Summary: Intraoperative measurements of lower esophageal sphincter (LES) including cross-sectional area, distensibility index, pressure, and high-pressure zone length were correlated with post-sleeve gastroesophageal reflux disease (GERD) symptoms after robotic sleeve gastrectomy. Patients with new or worsening GERD symptoms had higher distensibility index and lower LES pressure after surgery. An increase in GEJ CSA, pressure, and distensibility index, and a decrease in GEJ length can be expected during robotic sleeve gastrectomy.

Summary: Patients who undergo vertical sleeve gastrectomy (VSG) are at risk of postoperative gastroesophageal reflux disease (GERD). Abnormal preoperative pH studies and esophageal motility disorders are associated with higher rates of postoperative reflux after VSG. A DeMeester score greater than 24.8 predicts the occurrence of postoperative reflux in patients with abnormal preoperative pH studies.

Summary: The study aimed to evaluate the effectiveness, safety, and results of LSG and LSGFD in obese patients with or without GERD. The results showed that LSG and LSGFD had similar effects on weight loss and GERD resolution in obese patients. LSGFD also had a preventive effect on the occurrence and development of GERD. This suggests that LSGFD has clinical value in obese patients.

Summary: The study showed that overall, laparoscopic sleeve gastrectomy (LSG) does not significantly affect gastroesophageal reflux disease (GERD) symptoms, but patients without GERD prior to surgery may be at risk for new or worsening symptoms postoperatively. Further studies involving endoscopic, pathological, or manometry evaluations are necessary for a comprehensive understanding of LSG's impact on esophageal health.

Summary: This study compared the postoperative symptoms and complications of patients undergoing gastropexy with those who did not undergo gastropexy during LSG. The results showed that patients who underwent gastropexy had significantly reduced nausea, vomiting, reflux symptoms, and antiemetic drug use. Therefore, gastropexy can effectively alleviate postoperative LSG-related gastrointestinal symptoms and complications.

Summary: The prevalence and severity of erosive esophagitis (EE) increase after laparoscopic sleeve gastrectomy (LSG). Male gender and post-operative hiatal hernia are independent factors for an increased severity of EE after LSG. The incidence of severe EE after LSG is low for patients without pre-operative EE or grade A EE at baseline.

Summary: This study proposes a method for identifying spatial outliers in a river network by taking into account the effect of river flow connectivity. The proposed method, which uses river distance instead of Euclidean distance, is shown to have superior performance using a simulated river dataset. Its application on water quality data from the Sg. Klang Basin in Malaysia provides better identification of stations with significantly different water quality from their neighboring stations.

Summary: In this paper, a new estimation method is proposed for estimating optimal dynamic treatment regimes. The quadratic inference functions in myopic regret-regression (QIF-MRr) are used to estimate the parameters of the mean response at each visit. Singularity issues may arise when estimating the parameters in ODTR using QIF-MRr due to multicollinearity. Hence, the ridge penalty was introduced in rQIF-MRr to tackle the issues. Simulation study and application to anticoagulation dataset show that estimations using rQIF-MRr are more efficient than the QIF-MRr.

Summary: This systematic review aimed to determine the prevalence of micronutrient deficiency in individuals receiving long-term enteral nutrition (EN) and evaluate the associated factors and the effectiveness of interventions. The study found that common micronutrient deficiencies in EN recipients included copper, zinc, selenium, beta-carotene, and vitamins A, D, and E. Only deficiencies in copper, zinc, and selenium were associated with physical and hematological manifestations. The study also identified factors contributing to deficiency, such as inadequate nutrient formulation in feed products and nutritional decline prior to EN initiation. However, the certainty of evidence was very low, with a moderate to high level of bias, indicating the need for further research.

Summary: The study compared the 5-year gastroesophageal reflux outcomes of Laparoscopic Vertical Sleeve Gastrectomy (LVSG) and Laparoscopic Roux-en-Y gastric bypass (LRYGB) based on high-quality randomized controlled trials (RCTs). The results showed that LVSG was associated with a higher risk of adverse GERD outcomes at 5 years postoperatively compared to LRYGB, including overall worsened GERD, reoperations to treat severe GERD, and non-surgical management for worsened GERD. Appropriate patient/surgical selection is crucial to minimize these postoperative risks.
