Dear reader, here are the summaries of some of the latest papers from PubMed.

Bariatric Surgery:

• Source: The take-home message is that Roux-en-Y gastric bypass surgery significantly improves gastroesophageal reflux disease symptoms in obese patients, with only a low incidence of new-onset GORD.

• Source: Primary Roux-en-Y gastric bypass leads to sustained weight loss and remission of obesity-related diseases over 10 years in routine clinical care.

• Source: The take-home message is that laparoscopic reversal of Roux-en-Y gastric bypass can successfully resolve severe complications such as diarrhea, electrolyte imbalance, and weight loss, leading to full recovery.

• Source: The main finding of this paper is that bariatric surgery significantly improves eating disorders, depression, and anxiety in patients, as evidenced by a meta-analysis of observational studies. However, the results are heterogeneous due to varying assessment methods.

Liver Disease:

• Source: The take-home message of this paper is that Metabolic dysfunction-Associated Steatotic Liver Disease (MASLD) may carry a higher risk of sexual dysfunctions compared to other types of chronic liver diseases, with unknown impacts related to dietary patterns and quality of life.

• Source: The take-home message is that chronic liver diseases impair sex hormone metabolism and disrupt the hypothalamic-pituitary-gonadal axis, leading to sexual disorders including erectile dysfunction and infertility, yet these issues receive insufficient attention in clinical settings.

• Source: The take-home message is that the term “metabolic dysfunction-associated steatotic liver disease” (MASLD) has replaced “nonalcoholic fatty liver disease” (NAFLD) to better reflect the metabolic origins of the condition and improve patient understanding and acceptance.

• Source: The take-home message is that there is a critical need for developing reliable diagnostic biomarkers and effective treatments for Metabolic Associated Steatotic Liver Disease (MASLD) due to its prevalence and current management challenges.

• Source: The study shows that TRPA1 activation improves mitochondrial function and reduces liver steatosis in MASLD, suggesting TRPA1 as a potential therapeutic target for metabolic dysfunction-associated fatty liver disease.

• Source: The study suggests that maintaining ketogenesis in the liver may have a protective role against steatohepatitis progression, independent of total fat oxidation rates.

• Source: The study found that a 12-week walking intervention improved metabolic syndrome risk factors, liver function indicators, and liver ultrasound findings in older adults with both metabolic syndrome and MASLD.

• Source: The take-home message of this paper is that advancements in donor assessment and preservation techniques show promise for safely utilizing steatotic livers in transplantation, but further research is needed to standardize fat-content thresholds and improve risk stratification.

• Source: The study found that dietary naringin supplementation can reduce the risk and progression of metabolic dysfunction-associated fatty liver disease (MAFLD) by regulating gut microbiota, enhancing liver function, and influencing estrogen signaling.

• Source: The take-home message of this paper is that testosterone treatment can benefit older men with low testosterone levels, improving sexual function, anaemia, bone density, and diabetes risk, while being safe for the heart and prostate. However, further research is needed to determine its effects on lean mass loss due to weight loss medications and preventing disabilities in aging men.

• Source: The study identifies MEOX1 as a key transcription factor that promotes liver fibrosis in metabolic dysfunction-associated steatohepatitis (MASH) by activating hepatic stellate cells through SERPINE1, suggesting MEOX1 inhibition as a potential therapeutic target.

• Source: Ultrasound-derived fat fraction (UDFF) has significant diagnostic value for metabolic-associated fatty liver disease (MAFLD) in obese patients with polycystic ovary syndrome, correlating positively with the severity of MAFLD.

• Source: The take-home message of this paper is that patients with alcohol-related liver cirrhosis have a higher incidence of surgery for conditions like gallstones, gastrointestinal cancers, and hernias, despite surgeons’ reluctance due to complication risks.

Endoscopy:

• Source: The take-home message of this paper is that endoscopy is a critical and effective method for managing lower gastrointestinal anastomotic bleeding in IBD patients, though it requires careful technique, interdisciplinary collaboration, and consideration of potential complications.

• Source: Endoscopy is crucial for diagnosing, monitoring, and treating IBD, including assessing disease activity in post-operative patients with anatomical variations.

• Source: The take-home message is that early identification of high-risk patients with upper gastrointestinal bleeding through accurate, rapid, and non-invasive tools is crucial for improved clinical outcomes, especially with advances in endoscopic therapies.

• Source: The take-home message of this paper is that early surgical resection of nonviable bowel may offer a survival advantage in selected patients with hepatic portal venous gas and acute pancreatitis, despite high overall mortality rates.

• Source: GI transit abnormalities, including delays in gastric emptying, small bowel transit, and colonic transit, are relevant to the symptoms experienced by patients with IBS.
