    Simultaneous occurrence of follicular and papillary thyroid carcinomas in same thyroid lobe: A case series of six patients from Qatar2020In: International Journal of Surgery Case Reports, E-ISSN 2210-2612, Vol. 73, p. 65-70Article in journal (Refereed)
    Abstract [en]

    Background: Papillary thyroid carcinoma (PTC) and follicular thyroid carcinoma (FTC) are the first and second most common thyroid cancers comprising about 85% and 10% of all thyroid cancers. Simultaneous occurrence of medullary and papillary thyroid cancer has been reported with various presentations, but simultaneous occurrence of FTC in addition to PTC as differentiated cancers, is an unusual event that is rarely reported. Presentation of cases: We report our experience of six rare cases of synchronous coexistence of FTC and PTC with unique features. Case 1 is 31 old Egyptian female. Case 2 is a 61 year old Sudanese male. Case 3 is a 59 year old Sudanese male. Case 4 is a 56 years old Indian female. Case 5 is a 35 years old Filipina female. Case 6 is a 52 years old Qatari female. The six cases are special in their co-occurrence of two thyroid carcinoma, consisting of histologic features of follicular thyroid carcinomas, and classical papillary thyroid carcinoma, possibly the first case series of simultaneous occurrence of these two types of thyroid cancer in the Middle East and North Africa Region. Conclusions: We present rare cases of concurrent FTC and PTC. These six cases add more data highlighting the coincidental simultaneous coexistence of FTC and PTC. Endocrinologists and pathologists should be aware of and vigilant to this variety. © 2020 The Author(s)

    Is Revisional Gastric Bypass as Effective as Primary Gastric Bypass for Weight Loss and Improvement of Comorbidities?2020In: Obesity Surgery, ISSN 0960-8923, E-ISSN 1708-0428, Vol. 30, p. 1219-1229Article in journal (Refereed)
    Abstract [en]

    Background: Revisional gastric bypass (R-RYGB) surgery is utilized for the management of inadequate weight loss or weight regain observed after some cases of bariatric surgeries. Data on the mid-term effectiveness of primary gastric bypass (P-RYGB) compared to R-RYGB (e.g., post sleeve gastrectomy or gastric banding) are controversial. Methods: Retrospective chart review of all patients who received P-RYGB and R-RYGB (January 2011 - June 2015) at our center. One hundred and twenty patients who underwent P-RYGB and 34 R-RYGB who completed 18 months follow-up were included. We compared the effectiveness of P-RYGB with R-RYGB by assessing four anthropometric, two glycemic, and four lipid parameters, as well as the control of type 2 diabetes (T2DM), hypertension and dyslipidemia in terms of remission, improvement, persistence, relapse and de novo. The current study also assessed mortality and complications rates. Results: There were no significant differences in the baseline characteristics of patients who received P-RYGB with those who received R-RYGB in terms of age, gender and preoperative BMI. However, at 18 months: a) Patients who received P-RYGB had lower mean weight (P = 0.001) and BMI (P <0.001), reflected by a higher mean delta BMI (P = 0.02), TWL%(P <0.0001) and EWL%(P < 0.0001); b) No differences were observed between the two patients groups in terms of glycemic parameters, lipid profiles, and control of T2DM, hypertension, and dyslipidemia; and, c) No deaths were reported among both patients groups, and complication rates were comparable. Conclusion: Although R-RYGB effectively addressed inadequate weight loss, weight regain and recurrence of comorbidities after restrictive bariatric surgery, R-RYGB resulted in inferior weight loss compared to P-RYGB. There were no significant differences between the two procedures in terms of their clinical control of T2DM, hypertension and dyslipidemia. Both procedures exhibited comparable complication rates.

    Right ectopic paraesophageal parathyroid adenoma with refractory hypercalcemia in pregnancy: A case report and review of the literature2020In: International Journal of Surgery Case Reports, E-ISSN 2210-2612, Vol. 77, p. 229-234Article, review/survey (Refereed)
    Abstract [en]

    Introduction: Ectopic parathyroid adenoma is rare during pregnancy but poses multiple challenges in treatment. It presents as primary hyperparathyroidism which leads to symptoms and complications of hypercalcemia in both the mother and fetus. Presentation of case: A 38-year-old Sudanese female presented with diffuse bone pain and polyuria. Laboratory investigations revealed elevated serum calcium and parathyroid hormone. Ultrasound of the neck did not show any abnormal lesion, however 99mTc-sestamibi scan showed a right sided parathyroid adenoma, and an earlier CT scan showed the adenoma to be in an ectopic paraesophageal position. Focused surgical neck exploration was done, and the ectopic parathyroid adenoma was excised. Discussion: Preoperative localization of the ectopic parathyroid adenoma allows for a focused surgical procedure. Ultrasound is the safest during pregnancy, but 99mTc-sestamibi and CT scan may be necessary if ultrasound or initial bilateral neck exploration do not detect any adenoma. Mild elevations in maternal serum calcium can have detrimental effects on the fetus which suggests that a surgical approach may be necessary in the majority of cases. Conclusions: Ectopic parathyroid adenoma is rare during pregnancy and is detrimental to both the mother and fetus. Preoperative localization allows for a focused surgery which is a definitive treatment and can safely be performed during the 2nd trimester of pregnancy.

    First case of huge classic papillary thyroid cancer rupturing spontaneously leading to ischemic necrosis, perforation and inflammation of overlying skin: Case report and review of the literature2021In: International Journal of Surgery Case Reports, E-ISSN 2210-2612, Vol. 85, article id 106136Article in journal (Refereed)
    Abstract [en]

    Introduction: Papillary thyroid cancer (PTC) is the commonest form of well-differentiated endocrine carcinoma. It is categorized into indolent and aggressive, where the indolent subtypes (classic, follicular) rarely demonstrate aggressive behavior. We present a classic PTC presenting with a rapidly growing huge anterior neck mass that subsequently spontaneously ruptured subcutaneously resulting in ischemia, necrosis, and perforation of overlying skin leading to inflammation. Presentation of case: A 37-year-old female with no comorbidities presented to our emergency department with a neck swelling of 2 years duration that rapidly enlarged one week prior to presentation. Though the mass initially appeared of inflammatory nature, the tumor was a PTC, and she underwent total thyroidectomy with selective right side neck dissection and debridement of necrotic skin. The gross specimen revealed a fragmented non-intact right thyroid lobe mass causing pressure ischemia, necrosis and perforation of the skin. Histopathology showed a 9 × 9 × 5 cm classic PTC staged as pT3b N1b. Postoperative course was uneventful, she was discharged by the eighth postoperative day, and then she received a high dose of radioactive iodine ablation (RAI). Discussion: Classic PTC is usually of a smaller size and a relatively benign course compared to other PTC subtypes and thyroid cancers. It is indolent with favorable prognosis. Although it is associated with increased risk of lymph node metastases at the time of diagnosis, it is slow growing with high survival rates approaching 95%. Conclusion: Despite that classic PTC progresses slowly, it should still be suspected in neck swellings presenting with rapid and aggressive behavior. Prompt and systematic assessment is required with surgical intervention and radioactive iodine ablation therapy.

    First Case Report of Fulminant Hepatitis After Laparoscopic Sleeve Gastrectomy Associated with Concomitant Maximal Therapeutic Dose of Acetaminophen Use, Protein Calorie Malnutrition, and Vitamins A and D, Selenium, and Glutathione Deficiencies2021In: Obesity Surgery, ISSN 0960-8923, E-ISSN 1708-0428, Vol. 31, no 2, p. 899-903Article in journal (Refereed)
    Abstract [en]

    Nonalcoholic fatty liver disease (NAFLD) is increasingly being linked to obesity. Although laparoscopic sleeve gastrectomy (LSG) is effective for weight loss that can ultimately resolve NAFLD, an initial transient deterioration of liver functions could be observed during the first few months post-operatively, after which a subsequent improvement of the liver functions might occur. Rapid weight loss, nutritional deficiencies, and protein malnutrition can all contribute to hepatic dysfunction and can affect the metabolism of medications such as acetaminophen leading to more insult to a compromised liver. We report acute liver failure after LSG associated with protein calorie malnutrition, multiple nutritional deficiencies in addition to concomitant use of therapeutic doses of acetaminophen. Treatment with N-acetylcysteine, and replacement of deficient multivitamins and trace elements resulted in significant improvement in liver functions.

    Left iliac fossa mini-incision sigmoidectomy for treatment of sigmoid volvulus: Case series of six patients from Qatar2020In: International Journal of Surgery Case Reports, E-ISSN 2210-2612, Vol. 75, p. 534-538Article in journal (Refereed)
    Abstract [en]

    Background: Midline laparotomy is the definitive treatment for sigmoid volvulus after initial colonoscopic detorsion. We successfully adopted another technique at our center on 6 patients, treating sigmoid volvulus by left iliac fossa mini-incision. Presentation of cases: We report our experience of six non-consecutive cases of sigmoid volvulus treated by left iliac fossa mini-incision. The cases were a 33 year old Egyptian female, a 21 year old Bangladeshi male, a 58 year old Qatari male, a 30 year old Ethiopian male, a 36 year old Ugandan male, and a 58 year old Indian male. The six cases are unique in the surgical technique employed in their management. This is possibly the second case series of left iliac fossa mini-incision for sigmoid volvulus in the Middle East and North Africa Region. Discussion: All patients underwent initial colonoscopic detorsion followed by sigmoidectomy and anastomosis. The procedure was successful in treating the volvulus in five patients with no complication or recurrence over a mean follow up of 8 months (range: 1–36 months). One patient required further laparotomy and resection with anastomosis due to incompletely removed sigmoid colon. Conclusions: Left iliac fossa mini-incision for sigmoid volvulus is safe, feasible, cosmetically appealing and with low morbidity.

    Choroidal metastasis as initial presentation of aggressive medullary thyroid carcinoma with widespread mediastinal, brain, pituitary, bone, lung, and liver metastasis: Case report and literature review2021In: International Journal of Surgery Case Reports, E-ISSN 2210-2612, Vol. 87, no October 2021, article id 106419Article in journal (Refereed)
    Abstract [en]

    Introduction: Medullary thyroid carcinoma (MTC) is a neuroendocrine tumor that originates from the parafollicular C cells of the thyroid gland. MTC can be due to sporadic or hereditary causes due to gain of function germ line mutations in the RET proto-oncogene. MTC presenting as ocular symptoms due to choroidal mass is rare with bad prognosis. Presentation of case: A 38-year-old Sudanese male presented to Hamad General Hospital, complaining of sudden painless decrease of vision of the right eye of 3 weeks duration. After investigations using imaging methods, the patient was discovered to have metastatic MTC that presented as choroidal mass and metastasized to his lung, bone, brain, pituitary, liver and mediastinum. Discussion: In terms of investigations, serum levels of calcitonin have superior diagnostic accuracy. Our patient undertook diagnostic imaging including ultrasonography, fine needle aspiration and computerized tomography (CT) scan and/or MRI imaging. He undertook total thyroidectomy and left neck dissection followed by stereotactic radiosurgery for the right orbit and pituitary. He then received systemic anti-RET therapy (Selpercatinib). At 5 months follow up there was dramatic drop in CEA from 888 μg/L to 164 μg/L, and calcitonin from >585.2 pmol/L to 354 pmol/L. Conclusion: Choroidal metastasis as initial presentation of MTC is extremely rare and challenging to diagnose. Surgeons need a high index of suspicion when ocular symptoms accompany a neck mass or thyroid-related symptoms. MTC has a progressive course with involvement of blood vessels and neck lymph nodes. Choroidal metastasis of MTC is challenging to manage.

    What you see might not be what you get: Analysis of 15 prospective cases of non-invasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP)2022In: International Journal of Surgery Case Reports, E-ISSN 2210-2612, Vol. 91, article id 106751Article in journal (Refereed)
    Abstract [en]

    Introduction: Noninvasive follicular thyroid neoplasm with papillary-like nuclear (NIFTP) is a new entity. No previous study reported prospective cases, outlining using many quantitative and qualitative variables. Methods: Retrospective analysis of all (15) prospective NIFTP cases diagnosed between 2017 and 2021 at our institution. Statistical quantitative analysis outlined demographic, history, ultrasound, histopathology and treatment characteristics. Qualitative analysis examined the cases, with details provided on three cases to highlight the different possible presentations and configurations. Results: Mean age was 41.5 ± 9.91 years, 73.3% were females, and mean BMI was 29.49 ± 5.74 kg/m2. About 87% patients were symptomatic; 86.6% had neck swelling. Ultrasound (US) showed multiple nodules in 71.4% of cases. Fine-needle aspiration cytology (FNAC) showed that follicular lesion of undetermined significance (42.8%) was most common, followed by benign nodule (21.3%). Using the Bethesda System for Reporting Thyroid Cytopathology, 7 cases were category III, 3 category IV, 3 category II, and 1 category I. 60% of patients underwent total thyroidectomy. All cases were diagnosed postoperatively, 2 patients had additional papillary microcarcinoma. In 3 cases, the NIFTP site in the histopathology of resected specimen was different than the US-recommended site of the FNAC. Conclusion: We found discrepancies in the site and diagnosis of the preoperative US recommendation for the FNAC vs the postoperative histopathology of the specimen. These suggest that NIFTP might be incidentally and postoperatively diagnosed, irrespective of US or FNAC findings, hence its ‘true’ incidence might remain underestimated. As NIFTP cases higher BMI, Future research could predict preoperative diagnosis of NIFTP and explore associations with BMI.

    First bilateral non-invasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) co-occurring with bilateral papillary thyroid microcarcinoma: Case report and literature review2021In: International Journal of Surgery Case Reports, E-ISSN 2210-2612, Vol. 78, p. 411-416Article in journal (Refereed)
    Abstract [en]

    Introduction: Non-invasive follicular thyroid neoplasm with papillary-like features (NIFTP) is a recently characterized lesion with very low malignant potential. This has allowed for less aggressive management of this tumor subtype. Papillary thyroid carcinoma (PTC) has malignant potential and requires different considerations in management. Presentation of case: A 33-year-old woman presented to our Thyroid Surgery Clinic with a left neck swelling slowly enlarging over 4 years, and recent right-sided neck pain. Neck ultrasound and fine needle aspiration for cytology found bilateral thyroid nodules, labelled as ‘follicular lesion of undetermined significance’ (FLUS). Final pathology report after total thyroidectomy identified four distinct tumors: bilateral NIFTP lesions and bilateral papillary microcarcinomas. Discussion: Management of NIFTP comprises partial or total thyroidectomy without further intervention. Management of PTC is the same but with the possible addition of radioactive ablation due to the increased malignant potential. This is the first report of bilateral NIFTP lesions and bilateral papillary microcarcinomas co-occurring together in the same patient, so management was challenging. The decision was made to give the patient low dose radioactive iodine ablation and continue monitoring. Ultrasound of the neck follow up 6 months later showed no residual thyroid tissue or local recurrence. Conclusion: Although rare, NIFTP can co-occur with PTC. Bilateral NIFTP with bilateral PTC is extremely rare. Surgeons and pathologists need to be aware of this rare entity that can co-occur in both thyroid lobes. Total thyroidectomy is the definitive treatment. Post-surgery surveillance is important and follow up needs to be watchful for any recurrence or metastasis. © 2020 The Author(s)

    Largest case series of giant gallstones ever reported, and review of the literature2020In: International Journal of Surgery Case Reports, E-ISSN 2210-2612, Vol. 72, p. 454-459Article in journal (Refereed)
    Abstract [en]

    Introduction: Giant/large gallstones have high risk of complications, and technical difficulties during surgery. This case series is the largest ever reported. Presentation of cases: Case 1: Female (44 years), with one year intermittent right upper quadrant colicky pain. Ultrasound: large gallstone (normal gallbladder). Elective laparoscopic cholecystectomy (LC): 6 × 4 × 3.3 cm gallstone. Case 2: Female (41 years), presented to emergency room with 3 days right upper quadrant pain/tenderness, vomiting, and positive murphy's sign. Ultrasound: large gallstone, calculus cholecystitis. Emergency LC: 4.5 × 3.1 × 3.5 cm gallstone. Case 3: Male (38 years), with history of gallstones and acute cholecystitis presented with intermittent right upper quadrant pain (2 months) and vomiting. Normal abdominal examination. Ultrasound: large gallstone. Elective LC: 4.1 × 4 × 3.6 cm gallstone. Conclusions: Gallstones >5 cm are very rare, with higher risk of complications. Gallbladder should be removed even if asymptomatic. Gallstones >3 cm have increased risk for gallbladder cancer, biliary enteric fistula and ileus. LC has challenges that include grasping the gallbladder wall, exposure of Calot's triangle, and retrieval of gallbladder out of the abdomen. LC appears to be procedure of choice and should be performed by an experienced surgeon, considering the possibility of conversion to open cholecystectomy in case of inability to expose the anatomy or intraoperative difficulties. © 2020 The Author(s)

    Incidental appendiceal mucinous neoplasm mimicking a left adnexal mass: A case report2020In: International Journal of Surgery Case Reports, E-ISSN 2210-2612, Vol. 74, p. 132-135Article in journal (Refereed)
    Abstract [en]

    Introduction: Appendiceal mucinous neoplasm is a rare type of appendiceal tumors which can present in a variety of symptoms and is difficult to diagnose. Preoperative diagnosis depends mainly on diagnostic imaging such as ultrasonography and computerized tomography (CT) scan. This uncommon case report discusses an appendiceal mucinous neoplasm mimicking a left adnexal mass on presentation, physical examination and diagnostic imaging findings. Presentation of case: This is a 61-year-old female found to have a large left adnexal mass during follow up ultrasonography. The patient refused further imaging, and during laparotomy, she was found to have an appendicular mucocele with normal left and right ovaries. Discussion: Appendectomy was done and the final pathology came as appendiceal mucinous neoplasm. Her post-operative course and 3 years follow up were uneventful. Conclusions: The equivocal signs and symptoms along with the anatomical position of appendiceal mucocele makes it difficult to diagnose and can mimic other types of tumors. Therefore, it should be considered in the deferential diagnosis of lower abdominal and pelvic masses.

    Epidemiology, histopathology, clinical outcomes and survival of 50 cases of appendiceal mucinous neoplasms: Retrospective cross-sectional single academic tertiary care hospital experience2021In: Annals of Medicine and Surgery, E-ISSN 2049-0801, Vol. 64, article id 102199Article in journal (Refereed)
    Abstract [en]

    Background: Appendicular neoplasms are rare, most commonly as carcinoids followed by appendicular mucinous neoplasms (AMN). To date, there remains controversy regarding the best treatment of AMN and factors affecting its prognosis. Method: Retrospective chart review of patients operated for appendicular pathology (January 2011–December 2018, follow up to December 2020) at our institution. For all AMN patients, data included pre-operative clinical presentation, and operative/post-operative findings. Results: 12454 patients underwent appendectomy, of whom 50 (0.4%) had AMN histopathologically (mean age = 47.2). Most patients had laparoscopic appendectomy as primary surgery. Low grade AMN was the most common subtype (n = 41, 82%), and pseudomyxoma peritonei (PMP) was found in 8 (16%) patients. Based on histopathology and margin involvement, the 50 patients were categorized into 3 prognostic categories of recurrence risk (no risk, 24 patients; low risk, 8; high recurrence risk, 18 patients). Disease-free survival (DFS) was lowest for high recurrence risk group (P < 0.001). Eleven (22%) patients had AMN involving resection margin, of whom 3 had no completion surgery and had no recurrence. Higher tumor markers were associated with lower DFS, however it was not statistically significant. Conclusion: AMNs are rare but serious due to the risk of PMP. Laparoscopic approach for AMN may be feasible. Prognostic categories were significantly inversely correlated with recurrence risk; hence useful in predicting prognosis. Contrary to previous proposals, AMNs with acellular mucin at margin or local acellular mucin spillage may not require secondary surgery, especially if the patient is in low recurrence risk group. Tumor markers may predict risk of recurrence.

    Second ever reported case of central cause of unilateral foot drop due to cervical disc herniation: Case report and review of literature2021In: International Journal of Surgery Case Reports, E-ISSN 2210-2612, Vol. 83, article id 105928Article in journal (Refereed)
    Abstract [en]

    Background: Foot drop is defined as a weakness in the ankle and foot dorsiflexors. A disruption of the neural pathway starting from the motor prefrontal cortex and ending in the peroneal nerve can lead to foot drop. Foot drop due to lower motor neuron injury is well documented. However, foot drop due to a central cause of cervical disc prolapse is very rare. Case presentation: A 55-year-old male presenting with neck pain, right and left arms radicular pain and numbness, and unilateral right foot drop following cervical disc prolapse. The patient presented with upper motor neuron lesion signs. MRI showed cervical disc prolapse at two levels, confirming central cause of foot drop. The patient underwent anterior cervical decompression and fusion surgery. Discussion: Following decompression and fusion of involved cervical spine disc pathology, the patient had complete recovery of his right foot drop. Conclusions: Central causes, although rare, should be considered in the differential diagnosis of foot drop. Causes could be due to the compression effect of the cortico-spinal tract of the cervical spinal cord. Satisfactory results can be achieved upon correcting the causative lesion.

    Role of Newly Introduced Teledentistry Service in the Management of Dental Emergencies During COVID-19 Pandemic in Qatar: A Cross-Sectional Analysis2022In: Telemedicine journal and e-health, ISSN 1530-5627, E-ISSN 1556-3669, Vol. 28, no 11, p. 1623-1632Article in journal (Refereed)
    Abstract [en]

    Introduction: The lockdown imposed by the COVID-19 pandemic rendered teledentistry (TD) necessary to maintain the continuity of oral health services and avoid missing emergency dental conditions, while minimizing face-to-face visits. Our objective was to evaluate the ability of a newly introduced triage-based TD service to deliver its goals, by evaluating its processes and outcomes and assessing the demand for TD. Methods: This cross-sectional report assessed the triage processes and outcomes (triage category, referral to emergency/dental facility undertaken, remote medications prescribed, and procedures performed at the point of referral); and evaluated the demand for the newly introduced TD service during 5 months of the first wave of the pandemic. Results: Of 850 calls, about 70.6% of the samples were managed remotely; 29.4% were categorized as emergency/urgent and referred to the emergency/dental facility. Compared with other complaints, orofacial dental pain was the most common reason for the calls (41.6%, p < 0.0001). About 14.71% of callers received prescription for medications remotely. The most demanded disciplines were general dentistry, orthodontics, and oral surgery, respectively (p < 0.0001). Of those referred to a dental facility, 31.84% required no clinical intervention, 28.7% received orthodontic appliance repair, and 14.3% and 11.2% had urgent dental extractions or root canal treatments. Demand on the service fluctuated through various distinct stages of the lockdown. Conclusions: There has been continuous demand for the newly introduced TD service throughout the period of the current report despite the fluctuations, with most complaints managed remotely. TD was effective and suitable for triage, service delivery, and care during the pandemic.

    Is tele-diagnosis of dental conditions reliable during COVID-19 pandemic?: Agreement between tentative diagnosis via synchronous audioconferencing and definitive clinical diagnosis2022In: Journal of Dentistry, ISSN 0300-5712, E-ISSN 1879-176X, Vol. 122, article id 104144Article in journal (Refereed)
    Abstract [en]

    Objectives: To assess the reliability of synchronous audioconferencing teledentistry (TD) in making tentative diagnosis compared to definitive clinical face-to-face (CFTF) diagnosis; and whether agreement was influenced by dentist's experience, caller-patient relationship, and time of call. Methods: All patients calling the TD hotline during COVID-19 pandemic, triaged as emergency/ urgent and referred for CFTF care were included (N=191). Hotline dentists triaged the calls, made tentative audio-dentistry (AD) diagnosis, while dentists at point of referral made the definitive CFTF diagnosis. Cohen's weighted kappa (κ) assessed the extent of agreement between AD vs CFTF diagnosis. Results: There was significantly very good pair-wise agreement (κ = 0.853, P < 0.0001) between AD and CFTF diagnosis. AD diagnosis of pulpitis and periodontitis exhibited the most frequent disagreements. Tele-dentists with ≥ 20 years’ experience exhibited the highest level of agreement (κ =0.872, P < 0.0001). There was perfect agreement when mothers mediated the call (κ = 1, P < 0.0001), and very good agreement for calls received between 7 am-2 pm (κ = 0.880, P < 0.0001) compared to calls received between 2-10 pm (κ = 0.793, P < 0.0001). Conclusions: Remote tentative diagnosis using AD is safe and reliable. Reliability was generally very good but varied by dentist's experience, caller-patient relationship, and time of call. Clinical significance: The findings suggest that using AD in the home environment is safe and reliable, deploying providers with variable years of experience. The findings have generalizability potential to a variety of similar circumstances, healthcare settings and epi/pandemic situations.

    Presentation, diagnosis, management, and outcomes of prostatic abscess: comparison of three treatment modalities2020In: Therapeutic advances in urology, ISSN 1756-2872, Vol. 12, p. 1-8, article id 1756287220930627Article in journal (Refereed)
    Abstract [en]

    Purpose:

    The lack of available guidelines for the management of prostatic abscess (PA) results in inconsistencies in its management. The most commonly used management modalities were conservative treatment with parenteral antibiotics alone, transrectal ultrasound-guided (TRUS) needle aspiration, or transurethral deroofing (TUD).

    The current study is a retrospective study and examines prostatic abscess cases treated by either one or more of the different modalities. We assess and compare presentation, diagnosis, management, and outcomes of prostatic abscess and we compare the outcomes of the three management modalities.

    Methods:

    We retrieved the records of all patients (n = 23) admitted to the Urology department at Al Wakra hospital with the computed tomography (CT) diagnosis of prostatic abscess from January 2013 to March 2018. Data collected included demographic, clinical, laboratory, and imaging findings, as well as management modality, duration of hospital stay, duration of follow up, outcome, and recurrence.

    Results:

    A total of nine (39.1%) patients had conservative treatment only; eight (34.8%) had TUD, and six (26.1%) had TRUS needle aspiration. The mean age was 52.7 years. Lower urinary tract symptoms and fever were the most common presentations (95.7% and 82.6%, respectively). CT scan of the abdomen and pelvis with contrast was undertaken for all patients and it showed that multiple abscesses were observed in 14 (60.9%) cases.

    The overall mean hospital stay was 8.45 days (range 2–21 days). We observed no recurrences for patients treated conservatively or those who undertook TUD, but three patient (50%) recurrences were noted in TRUS aspiration patients. There was no mortality across the sample.

    Conclusion:

    Early diagnosis of prostatic abscess and prompt management may have decreased the morbidity and mortality. Conservative management can succeed in subcentimeter abscesses but TUD is the definite therapy for large and multiloculated abscess. TRUS aspiration does have a role in treatment, but it has higher recurrence and longer hospital stay.

    Grooved vs smooth ureteric stent before extracorporeal shockwave lithotripsy: Single-blind randomised clinical trial2022In: Arab Journal of Urology, ISSN 2090-598X, Vol. 20, no 1, p. 41-48Article in journal (Refereed)
    Abstract [en]

    Objective: No study compared the grooved stent to the widely used standard smooth (nongrooved) stent in humans. We compared stone clearance, complications, and patient tolerance of the grooved stent vs standard JJ stent. Patients and Methods: Single-blinded randomised trial among patients planned for pre-extracorporeal shockwave lithotripsy (ESWL) stenting. Adult patients with unilateral ureteric/ renal stones planned for ESWL were randomly assigned to receive (Percuflex) smooth ureteric stent or (Visiostar) grooved lithotripsy stent and blinded to the stent type. We collected and compared the baseline data and outcomes (stone-free rate, complications, and stent-related symptoms) of both patient groups. Results: A total of 96 adults were included (48 per arm). There were no significant differences between the groups at baseline in terms of demographics, body mass index, comorbidities, renal function, number of ESWL sessions, and stone characteristics, including pre-ESWL stone volume (mean [SD] smooth 310.2 [301.6] vs grooved 270.7 [278.6] mm3, P = 0.5). Stone clearance was statistically insignificant between the groups, although clinically relevant (smooth stent 70.8% vs grooved stent 81.2%, P = 0.2). Grooved-stent patients reported comparable urinary symptoms score (P = 0.05) and operative complications (P = 0.6), but significantly more urinary tract infections (UTIs) not requiring hospitalisation (P = 0.003). Conclusions: Although statistically insignificant, the grooved stent exhibited higher stone clearance compared to the smooth stent, with similar complication rates excpet that patients with grooved stents reported more UTIs. A re-visit to the size of the outer diameter of the grooved stent could enhance its stone clearance properties, and further development of its coating material could lead to better patient satisfaction.

    First ever case report of co-occurrence of hobnail variant of papillary thyroid carcinoma and intrathyroid parathyroid adenoma in the same thyroid lobe2020In: International Journal of Surgery Case Reports, E-ISSN 2210-2612, Vol. 70, p. 40-52Article in journal (Refereed)
    Abstract [en]

    Introduction: The hobnail variant of papillary thyroid cancer (PTC) is rare. Intrathyroid parathyroid adenoma (ITPA) is also rare. Co-ocurrence of PTC and ITPA in the same thyroid lobe is extremely rare. Likewise, primary hyperparathyroidism with such non-medullary thyroid carcinoma is rare. The specific molecular profile of hobnail PTC (HPTC) is different from the classic, poorly differentiated and anaplastic variants and may contribute to its aggressive behavior. HPTC's genetic profile remains unclear. Presentation of case: A 61-year-old woman presented to our endocrine clinic with generalized aches, bone pain, polyuria, and right neck swelling of a few months’ duration. Laboratory findings revealed hypercalcemia and hyperparathyroidism. Ultrasound of the neck showed 4.6 cm complex nodule within the right thyroid lobe. Sestamibi scan suggested parathyroid adenoma in the right thyroid lobe. Fine-needle aspiration (FNA) revealed atypical follicular lesion of undetermined significance. She underwent right lobectomy, which normalized the intraoperative intact parathyroid hormone levels. Final pathology with immunohistochemical stains demonstrated HPTC and IPTA (2 cm each). Next-generation sequencing investigated the mutation spectrum of HPTC and detected BRAFV600E mutation. Conclusions: A parathyroid adenoma should not exclude the diagnosis of thyroid carcinoma. Thyroid evaluation is needed for patients with primary hyperparathyroidism to prevent missing concurrent thyroid cancers. Cytomorphologic features to distinguish thyroid from parathyroid cells on FNA cytology must be considered. Immunohistochemical stains are important. BRAFV600E is the most common mutation in HPTC. This is possibly the first reported case of HPTC and ITPA co-occurring within the same thyroid lobe. Studies that define other molecular abnormalities may be useful as therapeutic targets. © 2020 The Author(s)

    Association of health status and health behaviors with weight satisfaction vs. Body image concern: Analysis of 5888 undergraduates in Egypt, Palestine, and Finland2019In: Nutrients, E-ISSN 2072-6643, Vol. 11, no 12, article id 2860Article in journal (Refereed)
    Abstract [en]

    Little is known about the relationships between weight satisfaction, body image concern, healthy nutrition, health awareness, and physical activity among college students across culturally different countries. We assessed country and sex-specific associations between health status (self-rated health, depression, BMI), healthy behavior (healthy nutrition, physical activity, health awareness), weight satisfaction, and body image concern via a cross-sectional survey (5888 undergraduates) in Egypt, Palestine, and Finland. This health and wellbeing survey employed identical self-administered paper questionnaires administered at several Universities in two Eastern Mediterranean countries (Egypt, Palestine—Gaza Strip), and an online-survey comprising the same questions in Finland. Regression analyses were employed. Health status variables exhibited the strongest associations; high BMI and more depressive symptoms were more often among students satisfied with their weight (except in Palestine), but they were positively associated with body image concern irrespective of country or gender. Self-rated health was not associated with body image concern or weight satisfaction. Healthy behaviors were not associated with body image concern or weight satisfaction. Depressive symptoms and BMI were the most prominent predictors for body image concern. There were country-specific consistent results when using the body image concern score. Further research is necessary to compare body image across different cultures and countries.

    Country and Gender-Specific Achievement of Healthy Nutrition and Physical Activity Guidelines: Latent Class Analysis of 6266 University Students in Egypt, Libya, and Palestine2017In: Nutrients, E-ISSN 2072-6643, Vol. 9, no 7, p. 1-12, article id 738Article in journal (Refereed)
    Abstract [en]

    Research on healthy behaviour such as physical activity and healthy nutrition and their combination is lacking among university students in Arab countries. The current survey assessed healthy nutrition, and moderate/vigorous physical activity (PA) of 6266 students in Egypt, Libya, and Palestine. We computed a nutrition guideline achievement index using WHO recommendation, as well as the achievement of PA recommendations using guidelines for adults of the American Heart Association guidelines. Latent class regression analysis identified homogenous groups of male and female students, based on their achievements of both guidelines. We examined associations between group membership and achievement of guidelines. A three-class solution model best fitted the data, generating three student Groups: "Healthy Eaters" (7.7% of females, 10.8% of males), "Physically Active" (21.7% of females, 25.8% of males), and "Low Healthy Behaviour" (70.6% of females, 63.4% of males). We did not observe a latent class that exhibited combined healthy behaviours (physically active and healthy eaters), and there were no major differences between countries. We observed a very low rate of healthy nutrition (approximate to 10% of students achieved greater than four of the eight nutrition guidelines), with little gender differences across the countries. About 18-47% of students achieved the PA guidelines, depending on country and gender, more often among males. Few females achieved the PA guidelines, particularly in Libya and Palestine. Culturally adapted multi-behavioural interventions need to encourage healthy lifestyles, nutrition and PA behaviours. National policies need to promote active living while addressing cultural, geographic, and other barriers to young adults' engagement in PA.

    Missing something? A scoping review of venous thromboembolic events and their associations with bariatric surgery: Refining the evidence base2020In: Annals of Medicine and Surgery, E-ISSN 2049-0801, Vol. 59, p. 264-273Article, review/survey (Refereed)
    Abstract [en]

    Background: Venous thromboembolic events (VTE) post-bariatric surgery (BS) lead to morbidity and mortality.

    Methods: This scoping review assessed whether reported VTE post-BS could be under/over-estimated; suggested a possible number of VTE post-BS; appraised whether VTE are likely to decrease/increase; examined BS as risk/protective factor for VTE; and mapped the gaps, proposing potential solutions.

    Results: VTE appears under-estimated due to: identification/coding of BS and VTE; reporting of exposure (BS); and reporting of outcomes (VTE). The review proposes a hypothetical calculation of VTE post-BS. VTE are unlikely to decrease soon. BS represents risk and protection for VTE. Better appreciation of VTE-BS relationships requires longer-term strategies.

    Conclusion: VTE are underestimated. Actions are required for understanding the VTE-BS relationships to in order to crease VTE by better-informed prevention strategy/ies.

    Missing Something? Comparisons of Effectiveness and Outcomes of Bariatric Surgery Procedures and Their Preferred Reporting: Refining the Evidence Base2020In: Obesity Surgery, ISSN 0960-8923, E-ISSN 1708-0428, Vol. 30, no 8, p. 3167-3177Article, review/survey (Refereed)
    Abstract [en]

    Comparisons of effectiveness of bariatric surgery (BS) procedures encompass weight loss, metabolic/clinical outcomes, and improvements or worsening of comorbidities. Post-operative physical activity (PA) and diet influence such outcomes but are frequently not included in comparisons of effectiveness. We assessed the value and necessity of including post-operative PA/diet data when comparing effectiveness of BS. Including post-operative PA/diet data has significant benefits for BS and patients. The paper proposes an explicit preferred reporting system (Preferred REporting of post-operative PHYsical activity and Diet data in comparisons of BS effectiveness: PRE-PHYD Bariatric). Including post-operative PA/diet data could result in more accurate appraisals of effectiveness of BS procedures. This could translate into better 'individualized' BS by achieving a better 'fit' between patient and procedure.

    Preoperative Prediction of Body Mass Index of Patients with Type 2 Diabetes at 1 Year After Laparoscopic Sleeve Gastrectomy: Cross-Sectional Study2022In: Metabolic Syndrome and Related Disorders, ISSN 1540-4196, E-ISSN 1557-8518, Vol. 20, no 6, p. 360-366Article in journal (Refereed)
    Abstract [en]

    Background: Very few models predict weight loss among type 2 diabetes mellitus (T2D) patients after laparoscopic sleeve gastrectomy (LSG). This retrospective study undertook such a task. Materials and Methods: We identified all patients >18 years old with T2D who underwent primary LSG at our institution and had complete data. The training set comprised 107 patients operated upon during the period April 2011 to June 2014; the validation set comprised 134 patients operated upon during the successive chronological period, July 2014 to December 2015. Sex, age, presurgery BMI, T2D duration, number of T2D medications, insulin use, hypertension, and dyslipidemia were utilized as independent predictors of 1-year BMI. We employed regression analysis, and assessed the goodness of fit and "Residuals versus Fits" plot. Paired sample t-tests compared the observed and predicted BMI at 1 year. Results: The model comprised preoperative BMI (β = 0.757, P = 0.026) + age (β = 0.142, P < 0.0001) with adjusted R2 of 0.581 (P < 0.0001), and goodness of fit showed an unbiased model with accurate prediction. The equation was: BMI value 1 year after LSG = 1.777 + 0.614 × presurgery BMI (kg/m2) +0.106 × age (years). For validation, the equation exhibited an adjusted R2 0.550 (P < 0.0001), and the goodness of fit indicated an unbiased model. The BMI predicted by the model fell within -3.78 BMI points to +2.42 points of the observed 1-year BMI. Pairwise difference between the mean 1-year observed and predicted BMI was not significant (-0.41 kg/m2, P = 0.225). Conclusions: This predictive model estimates the BMI 1 year after LSG. The model comprises preoperative BMI and age. It allows the forecast of patients' BMI after surgery, hence setting realistic expectations which are critical for patient satisfaction after bariatric surgery. An attainable target motivates the patient to achieve it.

    Weight Regain and Insufficient Weight Loss After Bariatric Surgery: Definitions, Prevalence, Mechanisms, Predictors, Prevention and Management Strategies, and Knowledge Gaps—a Scoping Review2021In: Obesity Surgery, ISSN 0960-8923, E-ISSN 1708-0428, Vol. 31, no 4, p. 1755-1766Article, review/survey (Refereed)
    Abstract [en]

    Some patients experience weight regain (WR) or insufficient weight loss (IWL) after bariatric surgery (BS). We undertook a scoping review of WR and IWL after BS. We searched electronic databases for studies addressing the definitions, prevalence, mechanisms, clinical significance, preoperative predictors, and preventive and treatment approaches including behavioral, pharmacological, and surgical management strategies of WR and IWL. Many definitions exist for WR, less so for IWL, resulting in inconsistencies in the reported prevalence of these two conditions. Mechanisms and preoperative predictors contributing to WR are complex and multifactorial. A range of the current knowledge gaps are identified and questions that need to be addressed are outlined. Therefore, there is an urgent need to address these knowledge gaps for a better evidence base that would guide patient counseling, selection, and lead to improved outcomes.

    Is routine preoperative esophagogastroduodenscopy prior to bariatric surgery mandatory?: Protocol for a systematic review and meta-analysis2020In: International Journal of Surgery Protocols, ISSN 2468-3574, Vol. 22, p. 1-5Article in journal (Refereed)
    Abstract [en]

    Introduction: Routine preoperative esophagogastroduodenscopy (p-EGD) prior to bariatric surgery (BS) is currently widely undertaken, and hence an important issue with many clinical and financial repercussions. Yet, the true extent of why p-EGD is routinely undertaken for all bariatric patients remains not well understood. Methods and analysis: To address this, we will undertake a systematic review and meta-analysis of routine p-EGD prior to BS from around the world. This protocol describes the methodological approach to be adopted and outlines the search strategies and eligibility criteria that will be employed to identify and select studies, and the way by which data from the selected studies will be extracted for analysis. PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), WHO International Clinical Trials Registry Platform, Cochrane Library, MEDLINE, Scopus, clinicaltrials.gov and Google scholar will be searched from 01 January 2000 to 30 April 2019 for original studies written in English that provided prevalence estimates of the outcomes of routine p-EGD prior to BS. STROBE criteria will assess the methodological quality of the selected studies. The use of fixed or random effects model will depend on the results of statistical tests for heterogeneity. Publication bias will be visually estimated by assessing funnel plots. Pooled estimates will be calculated. This protocol conforms to the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) guidelines and has been submitted for registration at the PROSPERO International Prospective Register of systematic reviews. No ethical clearance is required for this study. This review will be published in a peer- reviewed journal and will be presented at various national and international conferences. © 2020 The Author(s)

    Is Routine Preoperative Esophagogastroduodenoscopy Prior to Bariatric Surgery Mandatory?: Systematic Review and Meta-analysis of 10,685 Patients2020In: Obesity Surgery, ISSN 0960-8923, E-ISSN 1708-0428, Vol. 30, no 8, p. 3073-3083Article in journal (Refereed)
    Abstract [en]

    Background: This systematic review and meta-analysis searched, retrieved and synthesized the evidence as to whether preoperative esophagogastroduodenoscopy (p-EGD) should be routine before bariatric surgery (BS). Methods: Databases searched for retrospective, prospective, and randomized (RCT) or quasi-RCT studies (01 January 2000–30 April 2019) of outcomes of routine p-EGD before BS. STROBE checklist assessed the quality of the studies. P-EGD findings were categorized: Group 0 (no abnormal findings); Group 1 (abnormal findings that do not necessitate changing the surgical approach or postponing surgery); Group 2 (abnormal findings that change the surgical approach or postpone surgery); and Group 3 (findings that signify absolute contraindications to surgery). We assessed data heterogeneity and publication bias. Random effect model was used. Results: Twenty-five eligible studies were included (10,685 patients). Studies were heterogeneous, and there was publication bias. Group 0 comprised 5424 patients (56%, 95% CI: 45–67%); Group 1, 2064 patients (26%, 95% CI: 23–50%); Group 2, 1351 patients (16%, 95% CI: 11–21%); and Group 3 included 31 patients (0.4%, 95% CI: 0–1%). Conclusion: For 82% of patients, routine p-EGD did not change surgical plan/ postpone surgery. For 16% of patients, p-EGD findings necessitated changing the surgical approach/ postponing surgery, but the proportion of postponements due to medical treatment of H Pylori as opposed to “necessary” substantial change in surgical approach is unclear. For 0.4% patients, p-EGD findings signified absolute contraindication to surgery. These findings invite a revisit to whether p-EGD should be routine before BS, and whether it is judicious to expose many obese patients to an invasive procedure that has potential risk and insufficient evidence of effectiveness. Further justification is required.

    Behavioral risk factor clusters among university students at nine universities in Libya2018In: AIMS Public Health, ISSN 2327-8994, Vol. 5, no 3, p. 296-311Article in journal (Refereed)
    Abstract [en]

    Objectives: This study identifies and describes the clustering of 5 behavioral risk factors (BRFs) among university students. We also investigated whether cluster membership is associated with the students' self-rated academic performance and self-rated health. Material and methods: A sample of 1300 undergraduates at 6 universities and 3 colleges in Libya completed a self-administered questionnaire that assessed BRFs (nutrition, physical activity, alcohol consumption, smoking, illicit drug use, inadequate sleep). A two-step cluster analysis generated student clusters with similar lifestyles. Results: Two contrasting clusters of almost even size emerged (after exclusion of alcohol and illicit drug use due to very low prevalence). Cluster 1 comprised students with higher engagement in all forms of physical activity, higher levels of health consciousness, greater daily fruit/vegetable intake and better sleep patterns than students in cluster 2. Only as regards the consumption of sweets, cluster 1 students had less favorable practices than cluster 2 students. The prevalence of smoking was equally low in both clusters. Students in cluster 2, depicting a less healthy lifestyle, were characterized by a higher proportion of women, of students with less income and of higher years of study. Belonging to cluster 2 was associated with lower self-rated health (OR: 0.46, p < 0.001) and with lower self-rated academic performance (OR: 0.66, p < 0.001). Conclusion: Preventive programs should not address BRFs in isolation and should particularly target students with clustering of BRFs using specifically tailored approaches.

    Is achieving the guidelines of four forms of physical activity associated with less self-reported health complaints?: Cross-sectional study of undergraduates at the University of Turku, Finland2020In: International Journal of Environmental Research and Public Health, ISSN 1661-7827, E-ISSN 1660-4601, Vol. 17, no 15, p. 1-19, article id 5595Article in journal (Refereed)
    Abstract [en]

    Very little research has assessed the physical activity (PA) of university students in in Finland, and their associations with self-reported health complaints (HCs), whilst simultaneously accounting for a range of other potential confounders. Students at the University of Turku (1177) completed an online health and wellbeing questionnaire that assessed 22 physical and somatic HCs, and students’ achievement of the international guidelines of four forms of PA (moderate, vigorous, moderate-to-vigorous and muscle strengthening PA; MPA, VPA, MVPA, MSPA respectively). We also explored the associations between HCs and PA, controlling for sociodemographic and health confounders (age, sex, year of study, marital status, accommodation during semesters, health awareness). Factor analysis reduced the HCs into three factors (psychological, pains/aches, circulatory/breathing). Bivariate relationships (no controlling for confounders) between these 3 factors and four forms of PA guideline achievement showed significant effects of achieving the PA guidelines against various groups of HCs, where more strenuous PA was associated with significantly less HCs in a step-ladder pattern. Multiple regression analyses (controlling for confounders) showed that achievement of PA guidelines was significantly independently associated with self-reported HCs scores in most cases. Psychological HCs were negatively associated with achieving any type of PA; pains/aches were negatively associated with achieving two types of PA or with achieving MSPA guidelines; and circulatory/breathing HCs were negatively associated with achieving the VPA guidelines only. This is the first study in Finland to examine such relationships, and highlights the critical role of PA for the health of these young adults. Programs and policies to strengthen and improve the PA of university students would be beneficial, recognizing the benefits of instilling life-long PA habits among this group of young adults.

    Multi-substance use behaviors: Prevalence and correlates of alcohol, tobacco and other drug (ATOD) use among university students in Finland2021In: International Journal of Environmental Research and Public Health, ISSN 1661-7827, E-ISSN 1660-4601, Vol. 18, no 12, article id 6426Article in journal (Refereed)
    Abstract [en]

    Virtually no studies appraised the co-use of alcohol, tobacco, and other drug (ATOD) among Finn undergraduates. We assessed the associations between sociodemographic, health, academic, policy, and lifestyle characteristics (independent variables); and individual, multiple and increasing ATOD use (dependent variables) using regression analyses. Data were collected by online questionnaire at the University of Turku, Finland (1177 students). Roughly 22% of the sample smoked, 21% ever used illicit drug/s, 41% were high frequency drinkers, and 31.4%, 16.3%, and 6.7% reported 1, 2, or 3 ATOD behaviors respectively. Individual ATOD use was significantly positively associated with the use of the other two substances [adjusted odds ratio (Adj OR range 1.893–3.311)]. Multiple ATOD use was negatively associated with being single (p = 0.021) or agreeing with total smoking or alcohol ban policy on campus (p < 0.0001 for each); but positively associated with not living with parents (p = 0.004). Increasing ATOD behaviors were significantly less likely among those agreeing with total smoking or alcohol ban policy on campus (p range 0.024 to <0.0001). Demographics significant to either individual, multiple, or increasing ATOD use included males, being single, not living with their parents during semesters, and to some extent, religiosity. Age, depressive symptoms, perceived stress, self-rated health, health awareness, income sufficiency, and academic variables were not associated with individual, multiple, or increasing ATOD use. Education and prevention efforts need to reinforce abstinence from ATOD, highlight their harmful outcomes, and target risk groups highlighted above. University strategies should be part of the wider country-wide successful ATOD control policies. © 2021 by the authors. Licensee MDPI, Basel, Switzerland.

    Physical activity and mental health. Is achieving the physical activity guidelines associated with less depressive symptoms among undergraduates at the University of Turku, Finland?2021In: Central European Journal of Public Health, ISSN 1210-7778, E-ISSN 1803-1048, Vol. 29, no 3, p. 201-208Article in journal (Refereed)
    Abstract [en]

    OBJECTIVES: Virtually no previous research assessed physical activity (PA) of university students in Finland, and their associations with depressive symptoms, whilst simultaneously controlling for potential confounders. METHODS: Students at the University of Turku (1,177) completed an online health and wellbeing questionnaire that assessed depressive symptoms (22 items), as well as their achievement of the guidelines of four forms of low, moderate, vigorous, and muscle strengthening PA (LPA, MPA, VPA, MSPA, respectively). We explored the associations of depressive symptoms with these PA forms, accounting for socio-demographic and health confounders (age, gender, year of study, marital status, accommodation during semesters, self-rated health). RESULTS: Achievement of PA guidelines was generally low for these young adult Finnish undergraduates. Bivariate relationships (no controlling for confounders) between depressive symptoms and four forms of PA guidelines achievement showed that in males, good/very good/excellent self-rated health, and achievement of the MSPA guidelines were significantly negatively associated with depressive symptoms. Conversely, low PA was significantly positively associated with depressive symptoms. Multiple regression (controlling for confounders) showed that achievement of the MSPA guidelines was independently significantly negatively associated with depressive symptoms; and whilst achievement of the MPA and VPA guidelines was negatively associated with depressive symptoms, the relationships did not reach statistical significance. Likewise, low PA was positively associated with depressive symptoms, but the relationships were again not statistically significant. CONCLUSION: Universities would benefit from multipronged strategies and approaches employing effective interventions aimed at improving students' general awareness of their health and promoting more physically active lifestyles among students.

    Prevalence and predictors of smoking, quit attempts and total smoking ban at the University of Turku, Finland2021In: Central European Journal of Public Health, ISSN 1210-7778, E-ISSN 1803-1048, Vol. 29, no 1, p. 45-55Article in journal (Refereed)
    Abstract [en]

    OBJECTIVES: The current study employed socio-demographic, health and lifestyle, and academic variables to assess the prevalence and independent predictors of daily smoking, attempts to quit smoking, and agreement with total smoking ban at university. METHODS: Students at the University of Turku (1,177) completed an online questionnaire that assessed socio-demographic, health and lifestyle, and academic characteristics, and three smoking variables (smoking, attempts to quit, agreement with total smoking ban at university). Bivariate relationships and multiple logistic regression assessed relationships between student characteristics and the three smoking variables before and after controlling for all other variables. RESULTS: Slightly < 80% of students never smoked, 16% were occasional, and about 6% were daily smokers, and about 40% had attempted to quit. Nearly half the sample agreed to total smoking ban at university. Physical activity, consuming alcohol, illicit drug/s use and daily smoking were significant independent predictors across > 1 of the three smoking variables. Age, health awareness, importance of achieving good grades, academic performance compared to peers, study burden, and mother's educational level were significant independent predictors of one of the three variables examined. CONCLUSION: Universities need to assess smoking, with specific focus on the modifiable independent predictors that were associated with > 1 the variables examined, to encourage physical activity and pay attention to reduce alcohol consumption and illicit drug/s and daily smoking, whilst targeting at-risk students. University strategies should be part of the wider country-wide effective tobacco control policies.

    Is alcohol consumption associated with poor perceived academic performance?: Survey of undergraduates in Finland2020In: International Journal of Environmental Research and Public Health, ISSN 1661-7827, E-ISSN 1660-4601, Vol. 17, no 4, article id 1369Article in journal (Refereed)
    Abstract [en]

    The relationship between academic performance and alcohol consumption among students remains inconsistent. We assessed this relationship, controlling for sociodemographic characteristics across seven faculties at the University of Turku (1177 undergraduates). An online questionnaire assessed: seven sociodemographic characteristics (age, gender, year/discipline of study, accommodation type, being in intimate relationship, parental education, and income sufficiency); two perceived academic performance (students’ subjective importance of achieving good grades and students’ appraisal of their academic performance compared to peers); and six alcohol consumption behaviors (length of time, amount consumed, frequency, heavy episodic drinking, problem drinking, and possible alcohol dependence). Simple logistic regression assessed relationships between sociodemographic and academic variables with alcohol consumption behaviors; multiple logistic regression assessed the same relationships after controlling for all other variables. Students reported long duration and large amount of drinking (46% and 50%), high frequency of drinking (41%), heavy episodic drinking (66%), problem drinking (29%), and possible alcohol dependence (9%). After controlling, gender was associated with all alcohol consumption behaviors, followed by religiosity (associated with four alcohol behaviors), living situation, marital status, age (each associated with two alcohol behaviors), and parental education and year of study (each associated with one alcohol behavior). Study discipline, income sufficiency, importance of achieving good grades, and academic performance compared to peers were not associated with any alcohol behaviors. Universities need to assess problem drinking and alcohol use disorders among students. Prevention strategies are required to reduce risk. Health promotion efforts could focus on beliefs and expectations about alcohol and target student groups at risk for more efficient and successful efforts. © 2020 by the authors.

    Prevalence and socio-demographic, academic, health and lifestyle predictors of illicit drug/s use among university undergraduate students in Finland2020In: International Journal of Environmental Research and Public Health, ISSN 1661-7827, E-ISSN 1660-4601, Vol. 17, no 14, p. 1-20, article id 5094Article in journal (Refereed)
    Abstract [en]

    Illicit drug/s use (IDU) among university students is a public health concern. We assessed the associations between socio-demographic, academic, and health and lifestyle characteristics (independent variables) and regular, occasional or never IDU (dependent variables). Data were collected across seven faculties (1177 students) at the University of Turku (Finland) via an online questionnaire. About 1.5% of the sample had regular IDU, 19% occasional IDU, and 79% never IDU. Independent predictors of ever (lifetime) IDU included males [adjusted odds ratio (AOR) 1.82, P = 0.001], not living with parents (AOR 2.59, P < 0.001), singles (AOR 0.51, P < 0.001), lower religiosity (AOR 1.49, P = 0.022), better self-rated general health (AOR 0.41, P = 0.003), higher health awareness (AOR 1.93, P = 0.014), more depressive symptoms (AOR 1.82, P = 0.004), daily smokers (AOR 3.69, P < 0.001), heavy episodic drinking (AOR 2.38, P < 0.001) and possible alcohol dependency (AOR 2.55, P < 0.001). We observed no independent associations between ever IDU with age, study discipline, perceived stress or academic performance. The 20.5% ever IDU is concerning. The compelling independent predictors of ever IDU included not living with parents, lower religiosity, daily smokers, heavy episodic drinking and possible alcohol dependency (AOR range 2.38–3.69). Education and prevention need to emphasize the negative consequences to reinforce abstinence from IDU. Health promotion could focus on beliefs and expectations about IDU and target students at risk for successful efforts. © 2020 by the authors. Licensee MDPI, Basel, Switzerland.

    Adherence to Recommended Dietary Guidelines and the Relationships with the Importance of Eating Healthy in Egyptian University Students2018In: International Journal of Preventive Medicine, ISSN 2008-7802, E-ISSN 2008-8213, Vol. 9, no 1, article id 73Article in journal (Refereed)
    Abstract [en]

    Background: Little is known on the food consumption habits and adherence to dietary guidelines among young adults. We examined students' adherence to recommended guidelines, and the associations between importance of eating healthy and guidelines adherence. Methods: A total of 3271 undergraduates at 11 faculties, Assiut University, Egypt (2009-2010), completed a questionnaire reporting their consumption of 12 food groups; number of servings of fruits/vegetables/day; and how important it is for them to eat healthy. We employed the WHO guidelines for the Eastern Mediterranean region (WHO 2012) to compute students' adherence to dietary guidelines for the different food groups. Chi-square tested the differences for adherence to guidelines by gender, and the associations between the importance of healthy eating and guidelines adherence for the whole sample and by gender. Results: Except for cereal products, no food group had an adherence level >45%. Gender differences were observed (men had better adherence for sweets, cake/cookies, snacks, and raw vegetables but not for fast food/canned food or cooked vegetables, P < 0.001 for each). There was a significant positive trend between the increase of subjective importance of eating healthy and adherence to guidelines (P = 0.012-<0.001). However, this association was only for some food groups and gender dependent. Conclusions: Across the majority of food groups we examined, this sample exhibited low adherence levels to International Nutrition Guidelines. Healthier eating educational/intervention efforts should target foods exhibiting low adherence (most food groups, particularly salad/raw vegetables, fresh fruits, dairy/dairy products, meat/sausage products); consider gender differences (females reported lower adherence across most food groups); and note the relation between adherence and subjective importance of eating healthy by food groups and gender.

    Venous thromboembolic events after bariatric surgery: Protocol for a systematic review and meta-analysis2020In: International Journal of Surgery Protocols, ISSN 2468-3574, Vol. 22, p. 10-14Article in journal (Refereed)
    Abstract [en]

    Introduction: Considerably large numbers of bariatric surgery (BS) procedures are undertaken globally, and are projected to increase with the obesity epidemic. Venous thromboembolic events (VTE) comprise an important cause of postoperative morbidity and mortality after BS and an important issue with wide clinical and financial repercussions. Yet, a precise extent of the prevalence of VTE after BS for obesity and its mortality remains uncertain. Methods and analysis: In order to respond to this knowledge gap, we will conduct a systematic review and meta-analysis of the prevalence of and mortality associated with VTE after BS. This protocol outlines the methodology that will be used and the search strategies and eligibility criteria that will be utilized to identify and select studies, as well as the method by which data from the selected studies will be extracted for analysis. PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), WHO International Clinical Trials Registry Platform, Cochrane Library, MEDLINE, Scopus, clinicaltrials.gov and Google scholar will be searched from 01 January 1990 through 10th April 2020, for original studies written in English that provided prevalence estimates of VTE after BS. Articles will also be searched for mortality estimates of VTE after BS. STROCSS (Strengthening the Reporting of Cohort Studies in Surgery) criteria will evaluate the methodological quality of the selected studies. The use of fixed effect or random effects model will be subject to the findings of the statistical tests for heterogeneity. Publication bias will be visually estimated by inspecting the funnel plots. Pooled estimates will be computed. Th current protocol conforms to the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) guidelines and has been submitted to the PROSPERO International Prospective Register of systematic reviews. No ethical clearance is required for this study. This systematic review and meta-analysis will be published in a peer-reviewed journal and presented at national and international conferences. © 2020 The Author(s)

    Behavioral Health Risk Profiles of Undergraduate University Students in England, Wales, and Northern Ireland: A Cluster Analysis2018In: Frontiers In Public Health, ISSN 2296-2565, Vol. 6, article id 120Article in journal (Refereed)
    Abstract [en]

    Background: Limited research has explored clustering of lifestyle behavioral risk factors (BRFs) among university students. This study aimed to explore clustering of BRFs, composition of clusters, and the association of the clusters with self-rated health and perceived academic performance. Method: We assessed (BRFs), namely tobacco smoking, physical inactivity, alcohol consumption, illicit drug use, unhealthy nutrition, and inadequate sleep, using a self-administered general Student Health Survey among 3,706 undergraduates at seven UK universities. Results: A two-step cluster analysis generated: Cluster 1 (the high physically active and health conscious) with very high health awareness/consciousness, good nutrition, and physical activity (PA), and relatively low alcohol, tobacco, and other drug (ATOD) use. Cluster 2 (the abstinent) had very low ATOD use, high health awareness, good nutrition, and medium high PA. Cluster 3 (the moderately health conscious) included the highest regard for healthy eating, second highest fruit/vegetable consumption, and moderately high ATOD use. Cluster 4 (the risk taking) showed the highest ATOD use, were the least health conscious, least fruit consuming, and attached the least importance on eating healthy. Compared to the healthy cluster (Cluster 1), students in other clusters had lower self-rated health, and particularly, students in the risk taking cluster (Cluster 4) reported lower academic performance. These associations were stronger for men than for women. Of the four clusters, Cluster 4 had the youngest students. Conclusion: Our results suggested that prevention among university students should address multiple BRFs simultaneously, with particular focus on the younger students.

    Correlates of achieving the guidelines of four forms of physical activity, and the relationship between guidelines achievement and academic performance: Undergraduate students in Finland2017In: Central European Journal of Public Health, ISSN 1210-7778, E-ISSN 1803-1048, Vol. 25, no 2, p. 87-95Article in journal (Refereed)
    Abstract [en]

    Objectives: We surveyed and compared, by gender, the levels and correlates of achieving the international guidelines of four forms of physical activity (PA): moderate PA (MPA), vigorous PA (VPA), moderate or vigorous PA (MVPA), and muscle strengthening PA (MSPA). The study assessed the associations between achieving the guidelines of the four PA forms and a range of socio-demographic, health and academic performance variables. Methods: Data was collected across the seven faculties of the University of Turku (2013-2014 from a representative sample of 1,189 undergraduates). An English language online self-administered questionnaire assessed frequency and duration of PA/week for each form of PA. We employed cut-offs for the guidelines in accordance with the American Heart Association. Chi-square statistic tested the differences in PA, socio-demographic variables and academic performance between males and females. Binary logistic regression examined the factors associated with achieving the four PA guidelines and linear regression examined the association between the frequency of PA and academic performance. Results: Achievement of PA guidelines was relatively low across the sample. Female students were less likely to achieve the VPA or MSPA guidelines, but were more health conscious and in generally exhibited better academic performace than males. High health awareness and excellent/very good self-rated health were the strongest predictors of achieving all forms of PA. Parents' education level was positively related to likelihood of achieving the VPA, MVPA and MSPA guidelines. Achieving the MPA guidelines (but not VPA or MSPA) was positively associated with subjective perceptions of better academic performance. Conclusions: Achievement of PA guidelines was generally low for this sample of Finnish students, and was associated with positive health status and high health awareness. Universities need a holistic approach to improve awareness of health and promote PA in students' lifestyles.

    Are behavioural risk factors clusters associated with self-reported health complaints?: University students in Finland2023In: Central European Journal of Public Health, ISSN 1210-7778, E-ISSN 1803-1048, Vol. 31, no 4, p. 248-255Article in journal (Refereed)
    Abstract [en]

    OBJECTIVES: No previous research of university students in Finland assessed lifestyle behavioural risk factors (BRFs) and categorized students into clusters, explored the associations of the clusters with self-reported health complaints (HCs), whilst controlling for potential confounders. The current study undertook this task. METHODS: Students at the University of Turku (1,177) completed an online well-being questionnaire that assessed socio-demographic variables, 5 BRFs - problematic alcohol consumption, smoking, illicit drug use, food consumption habits, moderate-to-vigorous physical activity (MVPA), and 22 HCs. A food frequency questionnaire assessed students' consumption of a range of foods, and a dietary guideline adherence score was computed based on WHO dietary recommendations for Europe. Three separate regression models appraised the associations between the cluster membership and HCs factors, adjusting for sex, income sufficiency and self-rated health. RESULTS: Mean age was 23 ± 5.2 years, 77% had never smoked and 79% never used illicit drug/s. Factor analysis of HCs resulted in four-factors (psychological, circulatory/breathing, gastro-intestinal, pains/aches); cluster analysis of BRFs identified two distinctive student clusters. Cluster 1 represented more healthy students who never smoked/used illicit drugs, had no problematic drinking, and undertook MVPA on 4.42 ± 3.36 days/week. As for cluster 2 students, half the cluster smoked occasionally/daily, used illicit drug/s, and > 50% had problematic drinking and students undertook MVPA on 4.02 ± 3.12 days/week. More cluster 2 students adhered to healthy eating recommendations, but the difference was not significant between clusters. Regression analysis revealed that females, those with sufficient income, and with excellent/very good self-rated general health were significantly less likely to report all four HCs. Cluster 2 students were significantly more likely to report psychological complaints, circulatory/breathing and gastro-intestinal complaints. There was no significant association between BRFs clusters and pains/aches factor. CONCLUSIONS: Risk taking students with less healthy lifestyles and behaviour were consistently associated with poorer psychological and somatic health.

    First case of chronic cell leukemia discovered incidentally in extra-saccular inguinal lymph node during laparoscopic bilateral inguinal hernia repair: Case report and literature review2021In: International Journal of Surgery Case Reports, E-ISSN 2210-2612, Vol. 88, article id 106558Article in journal (Refereed)
    Abstract [en]

    Introduction: Chronic cell leukemia discovered incidentally in extra-saccular inguinal lymph node during laparoscopic bilateral inguinal hernia repair is extremely rare. Presentation of case: 62-year-old Romanian male presented at the outpatient general surgery clinic in April 2019 complaining of bilateral inguinal swelling that gradually increased in size mainly on right side and was diagnosed with bilateral inguinal hernia. During the laparoscopic repair of the hernia, a large lymph node in the left femoral canal was incidentally observed. Histopathologic, immunohistochemical, and flowcytometric evaluation of the excised specimen confirmed chronic lymphocytic leukemia/small lymphocytic lymphoma. Discussion: Whole body CT showed supra and infra-diaphragmatic lymphadenopathy, and few small subsolid pulmonary nodules, possibly metastatic. Splenomegaly and pancreatomegaly were also noted, suggesting lymphomatoid infiltration. Conclusion: There is need for cautious inspection and meticulous palpation of the inguinal area for any lymphadenopathy during routine inguinal hernia repair.

    Epidemiology and pathology of oral squamous cell carcinoma in a multi-ethnic population: Retrospective study of 154 cases over 7 years in Qatar2020In: Annals of Medicine and Surgery, E-ISSN 2049-0801, Vol. 60, p. 195-200Article in journal (Refereed)
    Abstract [en]

    Background: Oral cancer (OC) is a neoplastic process of the oral cavity that has high mortality and significant effects on patients’ aesthetics. The majority of OC is oral squamous cell carcinoma (OSCC) and resection remains the most frequent treatment. Recurrence is the main cause of tumor-related mortality. Material and methods: A retrospective review of patients’ charts at Hamad Medical Corporation examined 154 adults who were diagnosed as OSCC and referred to the national head and neck cancer multi-disciplinary team meetings between 2012 and 2018. The data extracted was demographic, pathologic and clinical. All patients with oral cavity tumors other than squamous cell carcinoma were excluded. Results: Males comprised the majority of the sample, mean age was 46.93 years. Tongue was the most common location. The majority of the patients were diagnosed at early stages, and a small subset of patients had histologically-proven local recurrence. Conclusion: The young male predominance of OSCC patients in Qatar is unprecedented worldwide. Most patients were non-Qataris, mainly from South Asia. Loss of follow-up was a challenge in assessing the long-term outcomes of OSCC. Our findings suggest the need for a more vigilant surveillance approach to oral lesions particularly in male South-Asian patients, as well as improving the follow-up strategies.

    Does varicocelectomy improve semen in men with azoospermia and clinically palpable varicocele?2020In: Andrologia, ISSN 0303-4569, E-ISSN 1439-0272, Vol. 52, no 2, article id e13486Article in journal (Refereed)
    Abstract [en]

    The effectiveness of varicocelectomy in nonobstructive azoospermia is controversial. The current study assessed the efficacy of microsurgical subinguinal varicocelectomy in nonobstructive azoospermic men with palpable varicocele and to evaluate predictive parameters of outcome. We reviewed the records of 723 patients who had microsurgical varicocelectomy and diagnostic testicular biopsy between 2012 and 2016 at a tertiary medical centre. Data pertaining to the physical, laboratory (semen analysis and hormonal profile) and histopathology features were examined, exploring the predictors of improvement in semen analysis post-varicocelectomy. In total, 42 patients with mean age 35.71 +/- 6.35 years were included. After a mean varicocelectomy follow-up of 6.7 months, motile spermatozoa in the ejaculate could be observed in 11 patients (26.2). Out of all the factors examined, only testicular histopathology significantly predicted post-varicocelectomy outcome, where 8/11 patients exhibited hypospermatogenesis, and 3/11 Sertoli cell-only regained spermatozoa in semen. Microsurgical varicocelectomy in nonobstructive azoospermic men with clinically palpable varicocele can result in sperm appearance in the ejaculate with the highest success expected in hypospermatogenesis.

    Geographical differences in semen characteristics of 13 892 infertile men2018In: Arab Journal of Urology, ISSN 2090-598X, Vol. 16, no 1, p. 3-9Article in journal (Refereed)
    Abstract [en]

    Objective: To assess the relationship between geographical differences and all semen parameters, across 13,892 infertile men of 84 diverse nationalities, recruited at a specialised tertiary hospital that represents the main healthcare provider in Qatar. Male infertility is an important and global public health problem. Despite this, there is a significant scarcity of epidemiological male infertility and semen analysis research in the Middle East and North Africa (MENA) region, as well as geographical comparisons with other parts of the world. Patients and methods: Retrospective study of semen findings of 13 892 infertile men assessed at the Male Infertility Unit at Hamad Medical Corporation, in Qatar between January 2012 and August 2015. Based on country of origin, patients were categorised into those from the MENA region (n = 8799) and non-MENA patients (n = 5093). The two groups were compared across demographic features and semen characteristics: age, sperm volume, sperm total motility, sperm progressive motility (PMot), abnormal sperm forms (ABF), and sperm DNA fragmentation (SDF). Results: The whole sample's mean (SD) age was 35.7 (0.7) years, sperm concentration was 32.3 (0.25) × 106 sperm/mL, total motility was 45.4 (0.2)%, sperm PMot was 25.1 (0.2)%, and ABF was 79.9 (0.2)%. Overall, 841 patients had azoospermia (6.05%), 3231 had oligospermia (23.3%), 4239 had asthenospermia (30.5%) and 6772 had teratospermia (48.7%). SDF (1050 patients) was abnormal in 333 patients (31.7%). MENA patients were significantly younger than their non-MENA counterparts and had a greater semen volume. Non-MENA patients had significantly higher sperm counts, total motility and PMot, and lower ABF. SDF showed no statistical difference between the two groups. MENA patients had significantly higher prevalence of oligospermia, asthenospermia, and teratospermia; and lower prevalence of normal sperm concentration, normal motility, and normal morphology. Throughout the 4 years of the study, MENA patients constantly had significantly lower sperm counts; generally lower sperm total motility percentage and generally lower quality sperm morphology. We compared patients by age (≤40 and &gt;40 years): in the patients aged ≤40 years, the same results as for the overall study were reproduced; in the &gt;40-years group, the same results were reproduced with the exception of morphology, which was not significantly different between the MENA and non-MENA patients. Conclusion: Semen quality is generally lower in male infertility patients from the MENA region compared to non-MENA regions. © 2018 Arab Association of Urology

    Factors associated with complete and partial remission, improvement, or unchanged diabetes status of obese adults 1 year after sleeve gastrectomy2020In: Surgery for Obesity and Related Diseases, ISSN 1550-7289, E-ISSN 1878-7533, Vol. 16, no 10, p. 1521-1530Article in journal (Refereed)
    Abstract [en]

    Background: Laparoscopic sleeve gastrectomy (SG) achieves type 2 diabetes (T2D) remission to various extents, and reasons for such variations are unknown. Objectives: We assessed patients’ characteristics associated with T2D remission 1 year post SG. Setting: University hospital. Methods: Retrospective study of 230 T2D patients (18–64 yr) who underwent SG at our institution. We examined pre- and postoperative demographic, anthropometric, biochemical, and clinical characteristics associated with T2D complete remission, partial remission, improvement, or unchanged status. Independent predictors of T2D complete remission were assessed by binary logistic regression and then included in 7 predictive models. Logistic regression assessed the pre- and postoperative predictors of T2D complete remission and their predictive performance was measured with the area under the curve of the receiver operating characteristic curve. Results: A total of 230 patients were included in the study, females comprised 69%, and mean age was 45.66 ± 8.84 years. Mean preoperative weight and body mass index were 115.69 ± 20.76 kg and 43.53 ± 6.98 kg/m2, respectively. Approximately two thirds (64.4%) of the sample had diabetes for &gt;5 years. Insulin therapy users comprised 36.9% of the sample and 29.6% of patients were on ≥2 oral hypoglycemic agents (OHA). At 1 year, mean body mass index was 32.77 ± 6.09 kg/m2, percent excess weight loss (%EWL) was 62.29 ± 23.60% and glycosylated hemoglobin (HbA1C) improved from 8.1% to 6.18%. Approximately 42.2% of the sample achieved T2D complete remission. Compared with those with no remission, patients with complete remission were significantly younger, had shorter duration of diabetes, were not on insulin therapy, took fewer OHA, had higher C-peptide, lower preoperative HbA1C, were less likely to have had hypertension or dyslipidemia, and more likely to have achieved higher %EWL. Seven proposed models for prediction of complete remission showed the most useful model comprised diabetes duration + pre-HbA1C + %EWL + insulin therapy + age + OHA (area under the curve = .81). Independent predictors of complete remission were preoperative HbA1C, %EWL, insulin therapy, age, and OHA (but not diabetes duration). Conclusion: SG results in significant weight reduction and various extents of T2D remission. HbA1C, %EWL, insulin therapy, age, and OHA were independent predictors of complete remission. Assessing these factors before bariatric surgery is important to identify any modifiable characteristics that can be altered to increase the likelihood of remission. © 2020 American Society for Bariatric Surgery

    Durability of Cardiometabolic Outcomes Among Adolescents After Sleeve Gastrectomy: First Study with 9-Year Follow-up2021In: Obesity Surgery, ISSN 0960-8923, E-ISSN 1708-0428, Vol. 31, no 7, p. 2869-2877Article in journal (Refereed)
    Abstract [en]

    Background: Long-term durability of weight loss and comorbidity resolution beyond 7 years after laparoscopic sleeve gastrectomy (LSG) among adolescents is completely lacking. Methods: Retrospective review of adolescents aged ≤ 18 years who underwent primary LSG at our institution between 2011 and 2015 (N = 146). We assessed anthropometric and cardiometabolic outcomes at 1, 3, 5, 7, and 9 years. Results: Follow-up rates were 57.53%, 82.87%, 85.24%, 83.92%, and 83.33% at the five time points. The preoperative mean body mass index (BMI) (45.60 ± 6.50 kg/m2) decreased at year 1 (30.04 ± 4.96 kg/m2, P=0.001) and was maintained up to 9 years (30.20 ± 3.92 kg/m2, P = 0.001). Remission rates were triglycerides, 100% (11/11) at 5 years, and 100% (1/1) at 9 years; high density lipoprotein, 89.4% (17/19) at 5 years, and 100% (3/3) at 7 years; low density lipoprotein, 71.4% (11/14) and 100% (3/3) at 5 and 7 years; total cholesterol, 70% (7/10) at 5 years, and 100% (2/2) at 9 years; uric acid, 100% (3/3) at 5 years. Remission of liver enzymes was 84.6–100% (22/26–2/2) at 5–9 years. Prediabetes remission was 87.5% (14/16 and 7/8) at 5 and 7 years and 100% (3/3) at year 9. Type 2 diabetes complete remission was 50% (3/6, 1/2) at years 5 and 7, with all cases resolved at 9 years. The only case of hypertension completely resolved. Conclusions: LSG achieved substantial weight loss and remission of cardiometabolic risk factors that were sustained on the long term. This is the first study among adolescents to assess such outcomes beyond 7 years. Graphical abstract: [Figure not available: see fulltext.].

    Effectiveness and Safety of Liraglutide in Managing Inadequate Weight Loss and Weight Regain after Primary and Revisional Bariatric Surgery: Anthropometric and Cardiometabolic Outcomes2022In: Obesity Surgery, ISSN 0960-8923, E-ISSN 1708-0428, Vol. 32, no 4, p. 1005-1015Article in journal (Refereed)
    Abstract [en]

    Background: No study appraised the effectiveness and safety of liraglutide in managing inadequate weight loss or weight regain (IWL/ WR) after primary versus revisional bariatric surgery (BS). Methods: Retrospective study of all eligible adults who completed liraglutide 3 mg therapy for IWL/WR after primary or revisional BS at our institution between May 2016 and June 2019 (N = 145; 119 primary, 82%; 26 revisional, 18%). Changes in anthropometric and cardiometabolic parameters were assessed before the start of liraglutide and at 6 and 12 months after treatment. Results: The mean age was 43.32 ± 10.49 years, and 83% were females. Patients received liraglutide at a mean of 54.10 ± 31.75 months after their BS, for WR (74.3%) or IWL (25.6%). Liraglutide significantly reduced weight and BMI among primary and revisional patients (P < 0.0001 for all) and was equally effective in these reductions for both groups. Primary patients achieved total weight loss percentage (TWL%) of 5.97% and 6.93% at 6 and 12 months. Additionally, 52.3% and 60% of the patients lost ≥ 5% of their total weight (TW) at 6 and 12 months after primary BS. Revisional patients achieved TWL% of 6.41% and 4.99% at 6 and 12 months, and 60% and 48% of patients lost ≥ 5% TW at the two time points. Liraglutide did not improve cardiometabolic outcome for primary patients; for revisional patients, only the systolic blood pressure decreased after treatment. Liraglutide was well tolerated, and the most common side effect was nausea. Conclusions: Liraglutide is useful as an adjunct weight loss medication for patients achieving unsatisfactory outcomes with BS. Graphical abstract: [Figure not available: see fulltext.]

    Multiple nutritional deficiencies among adolescents undergoing bariatric surgery: who is at risk?2022In: Surgery for Obesity and Related Diseases, ISSN 1550-7289, E-ISSN 1878-7533, Vol. 18, no 3, p. 413-424Article in journal (Refereed)
    Abstract [en]

    Background: Nutritional deficiencies among adolescents undergoing bariatric surgery (BS) have not been evaluated a in relation to patient's sex. Objectives: We compared the preoperative nutritional profile of adolescents characterized by sex and single versus multiple deficiencies. Setting: University hospital. Methods: Cross-sectional retrospective chart review of 415 eligible adolescents who underwent primary BS between 2011 and 2020. Data included preoperative demographic, anthropometric information as well as three sets of nutritional variables: anemia-related, calcium-related, and other nutritional variables. Results: The sample comprised 247 males (59.5%) with a mean age of 15.89 ± 1.03 years and a mean body mass index (BMI) of 47.80 ± 6.57 kg/m2. Most common deficiencies were vitamin D (92.3%), albumin (51.8%), anemia (15.9%), zinc (11.1%), and vitamin B12 (8%); 21.7% had hyperparathyroidism. Females exhibited a significantly higher prevalence of low hemoglobin, low hematocrit, and iron deficiency. Multiple deficiencies were present among 97.6%, 73.2%, 23.6%, 15%, and 12.6% of adolescents, who had vitamin D, albumin, hemoglobin, zinc, and vitamin B12 deficiencies, respectively. Univariate analysis revealed that adolescents with a BMI of ≥50 kg/m2 were 1.24 times more likely to have multiple deficiencies (P = .004). Using multivariate log-binomial regression, BMI of ≥50 kg/m2 was a significant predictor of multiple nutritional deficiencies (P = .005, adjusted risk ratio = 1.23, 95% CI 1.06–1.42). Age and sex were not independent predictors of multiple nutritional deficiencies. Conclusion: To our knowledge, this study is the first to appraise single and multiple nutritional deficiencies in adolescents undergoing BS by sex. Multiple deficiencies were common. Females are at higher risk of anemia-related deficiencies. A BMI of ≥50 kg/m2 independently and significantly predicted multiple nutritional deficiencies. Correction before and monitoring after surgery are important. © 2021 American Society for Bariatric Surgery

    Nutritional Deficiencies Among Adolescents Before and After Sleeve Gastrectomy: First Study with 9-Year Follow-up2022In: Obesity Surgery, ISSN 0960-8923, E-ISSN 1708-0428, Vol. 32, no 2, p. 284-294Article in journal (Refereed)
    Abstract [en]

    Background: Globally, only two studies appraised the long-term nutritional status of adolescents after laparoscopic sleeve gastrectomy (LSG). Methods: Retrospective chart review of all adolescents aged ≤ 18 years who underwent LSG with ≥ 5 years follow-up and had no subsequent revisional surgery (N = 146). We assessed 15 nutritional parameters preoperatively and at 1, 3, 5, 7, and 9 years post surgery. Results: Mean age was 16.51 ± 1.29 years, 51% were males. We identified three patterns:1) Significant worsening of preoperative deficiencies: 4.7% and 0.8% of the sample exhibited zinc and vitamin B12 deficiencies, worsening to 20.8% and 12.8% at 1 year, respectively. Likewise, 0.7% of the sample had low total protein, worsening to 8.3% at year 3. A total of 32.4% of females had preoperative low hemoglobin worsening to 57.9% at year 5.2) Significant improvement: the percentage of males with preoperative low hemoglobin (5.6%) was reduced to 4.1% and 5.1% at years 1 and 3, respectively.3) Persistent deficiency: all (100%) of adolescents had preoperative vitamin D deficiency that persisted through years 3 and 9 at 90.5% and 100%, respectively. The most common complications were food intolerance (51%), vomiting (47.5%), gastritis/ esophagitis (35.7%), and gastroesophageal reflux disease (20.3%). We observed one case of Wernicke’s encephalopathy. Across the 9 years, 15.4% of the adolescents underwent intra-abdominal surgeries where 12.6% had cholecystectomy and one patient had appendectomy. Conclusion: Adolescents had several preoperative nutritional deficiencies, most of which worsened or persisted on the long term. This is the first study among adolescents to assess such deficiencies beyond 5 years. Graphical Abstract: [Figure not available: see fulltext.].

    Evolution of 29 Anthropometric, Nutritional, and Cardiometabolic Parameters Among Morbidly Obese Adolescents 2 Years Post Sleeve Gastrectomy2018In: Obesity Surgery, ISSN 0960-8923, E-ISSN 1708-0428, Vol. 28, no 2, p. 474-482Article in journal (Refereed)
    Abstract [en]

    Background Laparoscopic sleeve gastrectomy (LSG) is a popular treatment for adolescent morbid obesity. Research on LSG outcomes among adolescents assessed a narrow range of anthropometric, nutritional, or cardiometabolic parameters, leading to an incomplete picture of these changes. We examined a wide variety of anthropometric, nutritional, and cardiometabolic parameters among adolescents before and after LSG. Methods We retrospectively reviewed medical charts of all obese adolescents who underwent LSG at Hamad Medical Corporation, Qatar, between January 2011 and June 2015 (N = 102). We assessed preoperative levels and postoperative changes in 4 anthropometric, 15 nutritional, and 10 cardiometabolic parameters. Results The study sample comprised 79 patients with complete information (36 males, mean age 15.99 +/- 1.1 years). At a mean of 24.2 months post-LSG, we observed (1) significantly reduced mean weight and body mass index by 51.82 +/- 28.1 kg and 17 +/- 6.24 kg/m(2), respectively; (2) the highest prevalence of post-LSG deficiencies pertained to vitamin D, albumin, and ferritin (89.3, 38, and 33.3%, respectively); (3) low hemoglobin levels (29.3%) only in females; (4) trace elements were not deficient; (4) significant reductions in percentage of adolescents with elevated low-density lipoprotein (from 66.1 to 38.9%), alanine aminotransferase (from 45.3 to 10.9%), and aspartate aminotransferase (from 24.1 to 8.6%) levels; (5) 100% remission of prediabetes cases; and (6) 80% remission of type 2 diabetes cases. Conclusions LSG achieved significant weight loss and improvement of cardiometabolic risk factors among adolescents. However, the slight worsening of preexisting nutritional deficiencies warrants careful preoperative surveillance and appropriate postoperative nutritional supplementation.

    Lorcaserin vs. Phentermine among non-surgical and surgical obese patients: Anthropometric, glycemic, lipid, safety and cost outcomes2019In: Annals of Medicine and Surgery, E-ISSN 2049-0801, Vol. 45, p. 75-81Article in journal (Refereed)
    Abstract [en]

    Background: To evaluate effectiveness, safety, and costs of Lorcaserin vs. phentermine among obese non–surgical and surgical patients (post bariatric surgery). Methods: This retrospective study retrieved charts of all patients (January 2013–June 2016) who received Lorcaserin or phentermine for 3 months. The study assessed anthropometric, glycemic, and lipid changes, as well as side effects and cost of medications among overweight and obese non-surgical (n = 83) and surgical patients (n = 46). These two patient groups were compared using Chi-square (χ2) and unpaired‘t’ test for qualitative and quantitative variables respectively. Results: At 3 months, among the non-surgical group, Phentermine patients had greater percentage of total weight loss (TWL%) (7.65 ± 8.26 vs. 2.99 ± 3.72%, P = 0.003), and greater BMI reduction (−3.16 ± 3.63 vs. −1.15 ± 1.53 kg/m2, P = 0.003) than Lorcaserin. Within the surgical group, Lorcaserin patients had significantly smaller TWL% (1.86 ± 5.06 vs. 7.62 ± 9.80%, P = 0.012), and smaller BMI reduction (−0.74 ± 1.80 vs. −3.06 ± 4.08 kg/m2, P = 0.012) than Phentermine. Lorcaserin exhibited significant total cholesterol and LDL improvements only among surgical patients with significant weight reduction (≥5% TW). Both medications were not associated with glycemic improvements among non-surgical and surgical groups. Phentermine had slightly more side effects but was less expensive. Conclusions: Among both patient groups, phentermine was more effective in achieving weight loss. Lorcaserin showed dyslipidemia improvements only among surgical patients who achieved significant weight reduction. Anti-obesity medications as part of weight management programs can result in weight loss among non-surgical and surgical patients, or halt weight regain among surgical patients. This is the first study to evaluate the effectiveness and safety of two anti-obesity medications (lorcaserin vs. phentermine) among two distinct obese patient groups, non-surgical and surgical patients.
