Abstract
Simple Summary Cystic renal disease (CRD) is a group of diseases characterized by abnormal sacs, or cysts, in the kidneys. CRD can be detected using certain imaging modalities (i.e., ultrasound). Patients with CRD might be symptoms-free, while others can show symptoms long after cysts development. Although these cysts represent structural changes, we hypothesized that they have an underlying biochemical alteration. If so, this would open the floor for potential biomarker discovery, which would aid in CRD diagnosis and, possibly, treatment. On that basis, this study focuses on identifying biomarkers for CRD. To achieve that, we employed a metabolomics-based approach to identify intermediate molecules inside the cells that are byproducts of biochemical reactions. We used dry blood spots and serum samples of CRD patients and healthy controls to study the differences in their metabolomic profile. Our results suggest that certain metabolites, including uridine diphosphate, cystine-5-diphosphate, and morpholine, are potential biomarkers for CRD. The affected biochemical pathways in CRD include aminoacyl-tRNA biosynthesis, purine, pyrimidine, glutathione, TCA cycle, and some amino acid metabolism. These preliminary results could be the starting point for possible diagnostic and therapeutic approaches for CRD in the future. Abstract Cystic renal disease (CRD) comprises a heterogeneous group of genetic and acquired disorders. The cystic lesions are detected through imaging, either incidentally or after symptoms develop, due to an underlying disease process. In this study, we aim to study the metabolomic profiles of CRD patients for potential disease-specific biomarkers using unlabeled and labeled metabolomics using low and high-resolution mass spectrometry (MS), respectively. Dried-blood spot (DBS) and serum samples, collected from CRD patients and healthy controls, were analyzed using the unlabeled and labeled method. The metabolomics profiles for both sets of samples and groups were collected, and their data were processed using the lab’s standard protocol. The univariate analysis showed (FDR p < 0.05 and fold change 2) was significant to show a group of potential biomarkers for CRD discovery, including uridine diphosphate, cystine-5-diphosphate, and morpholine. Several pathways were involved in CRD patients based on the metabolic profile, including aminoacyl-tRNA biosynthesis, purine and pyrimidine, glutathione, TCA cycle, and some amino acid metabolism (alanine, aspartate and glutamate, arginine and tryptophan), which have the most impact. In conclusion, early CRD detection and treatment is possible using a metabolomics approach that targets alanine, aspartate, and glutamate pathway metabolites.

Abstract
BACKGROUND Obesity is one of the leading causes of preventable death worldwide. Due to its increasing incidence and the difficulty in reducing its morbidity and mortality using nonsurgical methods, the demand for bariatric surgery has risen in recent times. Sleeve gastrectomy is one of the most common types of bariatric surgery, and like any other surgery, it carries a series of risks. CASE REPORT Although complications such as gastrointestinal leaks are widely reported, there is limited literature available on cutaneous complications. Here, we report 4 cases of patients showing a peculiar skin rash 2-4 weeks following sleeve gastrectomy. We also discuss some of the mechanisms that may underlie this correlation. CONCLUSIONS There is a need for further epidemiological studies to determine the prevalence of this rash. Further studies are also needed to determine the exact etiology of this rash.

Abstract
Background and Aims: We hypothesized that the prevalence of electronic cigarette vaping among the medical student population is on the rise. Our aims were to assess the prevalence of electronic cigarette vaping among medical students in Saudi Arabia, to understand and analyze the reasons that led them to try it, and to investigate students’ perceptions towards electronic cigarette vaping. Methods: An anonymous, paper-based, cross-sectional questionnaire was distributed amongst 401 undergraduate medical students from years 1-5 at Alfaisal University in Riyadh, Saudi Arabia. Prevalence, intensity of e-cigarette use and reasons for it, relation of electronic cigarettes to cessation of tobacco smoking, and side effects were studied. Results: The prevalence of vaping was 49/401 (12.2%). There was a strong association between gender and vaping, with males being 3 times more likely to vape compared to females (χ2 (1) =13.62, P <.001). The three most common reasons for using electronic cigarettes were to enjoy the variability in flavours (61.4%, n = 30), to reduce or quit tobacco cigarettes (29.5%, n = 14), and to avert the public smoking ban (13.6%, n = 7). The three most common side effects experienced by users were coughing (26.7%, n = 13), dry mouth/throat (24.4%, n = 12), and dizziness (20%, n = 10). Conclusion: Use of the electronic cigarettes is not uncommon amongst medical students, mostly due to their appealing flavor variability. Further research is required to define long-term safety and side effect profiles, and to generate evidence-based guidelines concerning e-cigarette safety and efficacy for smoking cessation.

Abstract
BACKGROUND Pancreaticoduodenectomy (Whipple procedure) is an established surgical procedure for the treatment of carcinoma of the head of the pancreas. Modifications to this procedure include gastropancreaticoduodenectomy, which includes the removal of parts of the pancreas, duodenum, and stomach. Complications of surgery include fistula formation, failure of the anastomosis, and leak of pancreatic enzymes, which can be reduced by stenting the pancreatic duct. This report is of a rare complication of pancreaticoduodenectomy and describes a case of retrograde migration of a pancreatic duct stent into the biliary tract through the orifice of the hepaticojejunostomy. CASE REPORT A 50-year-old man with a history of gastric cancer, underwent gastropancreaticoduodenectomy. Surgery was complicated by displacement of the pancreatic stent to the biliary system, which resulted in postoperative obstructive jaundice and bile leakage from the hepaticojejunostomy between the hepatic duct and the jejunum. An endoscopy was performed and the stent was successfully retrieved. The patient recovered rapidly, the bile leakage resolved, the patient's jaundice resolved, and was discharged home with no further surgical complications. CONCLUSIONS A case is reported of a rare early complication of pancreaticoduodenectomy in a patient with gastric cancer. Endoscopy successfully retrieved the pancreatic duct stent that had migrated into the biliary tract through the orifice of the hepaticojejunostomy.
