Abstract [en]

Background: /aim: Scores commonly employed to risk stratify perforated peptic ulcer patients include ASA (American Society of Anesthesiologists), Boey and peptic ulcer perforation score (PULP). However, few studies assessed and compared the accuracy indices of these three scores in predicting post PPU repair 30-day morbidity. We assessed accuracy indices of PULP, and compared them to Boey and ASA in predicting post perforated duodenal (PDU) ulcer repair 30-day morbidity. Methods: Retrospective chart review of all PDU patients (perforated duodenal ulcers only) at the largest two hospitals in Qatar (N = 152). Data included demographic, clinical, laboratory, operative, and post repair 30-day morbidity. Area under the Curve (AUC), sensitivity and specificity were computed for each of the 3 scores. Multivariate logistic regression assessed the accuracy indices of each score. Results: All patients were males (M age 37.41 years). Post PDU repair 30-day morbidity was 10.5% (16 morbidities). Older age, higher ASA (≥3), Boey (≥1) or PULP (≥8) scores, shock on admission and preoperative comorbidities; and conversely, lower hemoglobin and albumin were all positively significantly associated with higher post PDU 30-day morbidity. PULP displayed the largest AUC (72%), and was the only score to significantly predict 30-day morbidity. The current study is the first to report the sensitivity and specificity of these three scores for post PDU repair 30-day morbidity; and first to assess accuracy indices for PULP in predicting post PDU repair 30-day morbidity. Conclusion: PULP score had the largest AUC and was the only score to significantly predict post PDU repair 30-day morbidity. © 2019 The Author(s)

Abstract [en]

Background Obesity is a risk for many different cancers. Laparoscopic sleeve gastrectomy (LSG) is common, and benign or pre-malignant histopathology types are reported in the removed gastric specimens. We assessed whether higher BMI was associated with certain benign or pre-malignant histopathological changes. Method Retrospective chart review of all primary LSG patients (N = 1555). Demographic, clinical, and LSG histopathology data were retrieved. BMI of patients with specific benign or pre-malignant conditions in their gastric specimens was compared with the BMI of the rest of the patients with abnormal histopathology specimens and also compared with the BMI of patients with normal control specimens. Results Females comprised 70% of the patients. Mean BMI were 46.3 (females) and 48 (males). Normal LSG specimens comprised 52%. Most common abnormal histopathologies were chronic inactive gastritis (33%), chronic active gastritis (6.8%), follicular gastritis (2.7%), lymphoid aggregates (2.2%), intestinal metaplasia (1.4%) and GIST (0.7%). After controlling for confounders (age, gender, H. pylori, diabetes mellitus type 2, hypertension), no significant association was observed between the BMI of patients with specific benign or pre-malignant histopathology compared with the BMI of the rest of the patients with abnormal histopathologies and compared to the BMI of patients with normal histopathologies. Conclusion When confounders were taken into account, there appeared no significant associations between the BMI of patients with specific benign or pre-malignant histopathology compared with the BMI of the rest of the patients with abnormal histopathologies and compared to the BMI of patients with normal histopathologies of their gastric specimens. There was a very weak correlation between BMI and other covariates.

Abstract [en]

Introduction: Amyand's hernia (AH) is rare, schistosomiasis of the appendix is very uncommon, and both conditions coexisting together is an extremely rare event. Pre-operative diagnosis of each of the two conditions is usually difficult. To the best of our knowledge, the current paper is first to report both these two conditions in coexistence. Presentation of case: A 31-year old man who had no comorbidities was admitted electively as a day case of non-complicated right indirect inguinal hernia. Further history and physical examination were unremarkable. Intraoperatively the patient was found to have right sliding AH with appendicular schistosomiasis (AS). The patient underwent Lichtenstein repair of the hernia with appendectomy. On follow up he was referred to infectious disease clinic, and the post-operative course was uneventful. Conclusions: Intraoperative identification of non-typical hernia sac before its opening should alert the surgeon to the possibility of sliding hernia and the presence of an organ as a part of the sac. Rare causes of appendicular masses like schistosomiasis granuloma should be considered in endemic areas or immigrants from these areas, despite the difficulty of preoperative diagnosis. Management should follow general guidelines of appendectomy, hernia repair and dealing with the associated pathology if present.

Abstract [en]

Background: Gallbladder cancer (GC) is a relatively rare disease. To date, there are no studies describing the epidemiology of this disease in Qatar. Objective: To study the epidemiology of Gallbladder Cancer in Qatar. Methods: A retrospective analysis of the cases of GC in Hamad General Hospital in Qatar from 2009 to 2016. Results: Thirty-five patients presented with GC during the study period, 10 females (28.6%) and 25 males (71.4%). Fourteen patients (40%) were diagnosed incidentally after laparoscopic cholecystectomy, 16 (48.6%) were diagnosed pathologically, and 4 (11.4%) were diagnosed radiologically. The median age at diagnosis was 54 years (31–78). 74.3% of the disease occurred in patients less than 60 years old. Metastatic disease was discovered in 25 patients (71.4%) versus no metastasis in 10 patients (28.6%). The most common sites for metastasis were the liver (42.9%), peritoneum (25.7%), and lymph nodes (25.7%). Curative central hepatic resection was done in 8 patients (22.9%). Pathology showed adenocarcinoma in 27 patients (77.1%), neuroendocrine tumor in 3 patients (8.6%) and high-grade dysplasia in 1 patient (2.9%). No histopathology was available for 4 patients (11.4%). Twenty-eight patients (80.0%) had regular follow up, with 22 (62.9%) still alive. Six patients (17.1%) died during follow up with survival after diagnosis ranging from 42 days to 6.8 years. Conclusions: In Qatar, due to the unique demographics, GC is more common in males and younger age groups. Most of the patients present late with metastasis, but curative resection is associated with long-term survival.

Abstract [en]

Background and study aims: Hepatocellular carcinoma (HCC) with extrahepatic metastasis has been studied, however, data from the Middle East remain scarce. In this study, we assess epidemiology of HCC in Qatar, and identify predictors of the metastatic behaviour. Patients and methods: All newly-diagnosed HCC patients on top of liver cirrhosis between 2011 and 2015 were included in the study. Results: A total of 180 patients met our inclusion criteria. The mean age was 58.8 ± 10.5 years with a mean follow-up of 1.0 ± 1.1 years. There were 150 male patients and HCV was the most common cause of liver cirrhosis 108 (60%), and 22 (12.2%) patients were classified as Child-Pugh class C. The overall survival of 51.1%, and 47 (26%) had at least one extrahepatic metastasis at the time of diagnosis. Single site metastasis was diagnosed in 10 patients, whereas 37 patients had multiple sites metastases. We compared patients who had metastases with patients who did not have metastasis at the time of diagnosis of HCC regarding several variables, and analysis revealed that tumour diameter larger than 5 cm (OR = 6.10, 95% CI = 1.85–20.12) (p = 0.003), and bilobar liver involvement (OR = 5.49, 95% CI = 1.10–27.30) (p = 0.037) were independent predictors of metastatic behaviour of HCC. Conclusion: The incidence of HCC is rising in our population, extrahepatic metastasis is no longer rare and tumours larger than 5 cm and bilobar involvement are determinants of the extrahepatic metastasis. © 2019 Pan-Arab Association of Gastroenterology

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.

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.

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.

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.

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.
