Metabolic and bariatric surgeries (MBS), including Roux-en-Y Gastric Bypass (RYGB) and Sleeve Gastrectomy (SG), have proven effective in promoting long-term diabetes remission among patients with type-2 diabetes (T2D). In this multicentre retrospective cohort study, we investigated the effectiveness of RYGB and SG in achieving diabetes remission, specifically among patients with T2D and vascular complications, while accounting for similar baseline diabetes severity. Although various scores predict diabetes remission after bariatric surgery, they do not consider diabetes-related vascular complications, which can influence outcomes even in patients with similar baseline T2D severity.

Biliopancreatic diversion with duodenal switch (BPD-DS) and single anastomosis duodeno-ileostomy with sleeve (SADI-S) are associated with superior and sustained weight loss outcomes. Despite their growing popularity, long-term safety profiles, particularly the risk of internal hernia (IH), remain underexplored. This study aimed to evaluate the incidence and characteristics of IH following BPD-DS and SADI-S procedures, comparing their clinical presentation, diagnostic methods, and outcomes.

Article Synopsis
  • Surgical resection is a primary treatment for pancreas ductal adenocarcinoma (PDAC), but patient outcomes vary due to social determinants of health (SDH), particularly influenced by the area deprivation index (ADI).
  • A study analyzing 1,001 PDAC patients revealed that those from more marginalized backgrounds (higher ADI) were 1.57 times more likely to lose follow-up care after surgery compared to less marginalized individuals.
  • The findings highlight the need to address SDH to improve care continuity for marginalized patients, suggesting that future efforts should focus on reducing the barriers they face in accessing healthcare.

Article Synopsis
  • A study was conducted on 628 patients who underwent pancreatoduodenectomy (PD) for pancreatic cancer to analyze long-term reoperation rates and reasons for these surgeries.
  • Results showed that 30% of patients required any additional surgery within 5 years, and 21.2% had reoperations related to the initial PD, most commonly due to cancer recurrence and incisional hernias.
  • The findings indicate that while a significant number of patients experienced further surgeries, the specific rates for serious complications were relatively low.

Article Synopsis
  • Tranexamic acid is known to reduce bleeding and blood transfusions in various surgeries, but its effectiveness for patients undergoing liver resection due to cancer is uncertain.
  • A multicenter randomized clinical trial involving 1384 patients was conducted to see if tranexamic acid decreases the need for red blood cell transfusions within 7 days after liver surgery.
  • The results showed no significant difference in transfusion rates or blood loss between the tranexamic acid group and the placebo group, and those who received tranexamic acid experienced more complications.

Metabolic and Bariatric Surgery (MBS) is effective in improving metabolic outcomes and reducing weight in patients with obesity and diabetes, with less explored benefits in type 1 diabetes (T1D). This study aimed to evaluate the impact of MBS on weight loss and insulin requirements in T1D patients compared to insulin-treated type 2 diabetes (T2D) patients over a 5-year period. This retrospective analysis included patients who underwent primary sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) with a confirmed preoperative diagnosis of either T1D or insulin-treated T2D.

Article Synopsis
  • The study investigates the use of von Willebrand factor antigen (vWF-Ag) as a non-invasive biomarker to assess complications related to portal hypertension and predict patient outcomes in hepatocellular carcinoma (HCC) after liver resection.
  • The research found that vWF-Ag levels were strongly linked to time to recurrence and overall survival, with specific cutoff values indicating significant risk for posthepatectomy liver failure (PHLF) and clinically significant portal hypertension (CSPH).
  • Results suggest that measuring vWF-Ag could enhance preoperative risk assessment for patients with resectable HCC, potentially guiding treatment decisions based on identified risk levels.

The relationship between primary productivity and diversity has been demonstrated across taxa and spatial scales, but for organisms with biphasic life cycles, little research has examined whether productivity of larval and adult environments influence each life stage independently, or whether productivity of one life stage's environment outweighs the influence of the other. Experimental work demonstrates that tadpoles of stream-breeding anurans can exhibit a top-down influence on aquatic primary productivity (APP), but few studies have sought evidence of a bottom-up influence of primary productivity on anuran abundance, species richness and community composition, as seen in other organisms. We examined aquatic and terrestrial primary productivity in two forest types in Borneo, along with amphibian abundance, species richness, and community composition at larval and adult stages, to determine whether there is evidence for a bottom-up influence of APP on tadpole abundance and species richness across streams, and the relative importance of aquatic and terrestrial primary productivity on larval and adult phases of anurans.

Background: The absence of surgical complications has traditionally been used to define successful recovery after pancreas surgery. However, patient-reported outcome measures as metrics of a challenging recovery may be superior to objective morbidity. This study aims to evaluate the use of patient-reported outcomes in assessing recovery after pancreas surgery.

Background: The management of invasive intraductal papillary mucinous cystic neoplasm (I-IPMN) does not differ from de novo pancreatic ductal adenocarcinoma (PDAC); however, I-IPMNs are debated to have better prognosis. Despite being managed similarly to PDAC, no data are available on the response of I-IPMN to neoadjuvant chemotherapy.

Methods: All patients undergoing pancreatic resection for a pancreatic adenocarcinoma from 2011 to 2022 were included.
