Secondary bile acid derivatives are contributors to the fecal bile acid pool and associated with bile acid modulating nutrients.

Objective: Accumulation of hydrophobic bile acids is linked with cancer development. However, derivatives of deoxycholic acid (DCA) and lithocholic acid (LCA) produced via bacterial metabolism may mitigate the proinflammatory and cytotoxic effects of hydrophobic bile acids. The impact of diet on secondary bile acid (BA) derivative production has not been determined.

Predictive Modeling Is a Reliable Indicator in Determining Excessive Renal Mobility Single-Center Randomized Study.

Excessive kidney mobility is an underestimating challenge for surgeons during retrograde intrarenal surgery (RIRS) and extracorporeal shock wave lithotripsy (ESL). There is no technique approved as a gold standard procedure for reducing excessive kidney mobility. The study aimed to uncover predictive factors for determining excessive renal mobility by utilizing clinicodemographic characteristics and noncontrast computed tomography (NCCT) data.

Advances for Managing Pancreatic Cystic Lesions: Integrating Imaging and AI Innovations.

Pancreatic cystic lesions (PCLs) represent a spectrum of non-neoplasms and neoplasms with varying malignant potential, posing significant challenges in diagnosis and management. While some PCLs are precursors to pancreatic cancer, others remain benign, necessitating accurate differentiation for optimal patient care. Conventional approaches to PCL management rely heavily on radiographic imaging, and endoscopic ultrasound (EUS) guided fine-needle aspiration (FNA), coupled with clinical and biochemical data.

Can we predict postoperative fever and urinary tract ınfection after retrograde ıntrarenal surgery? Results of a case control matching multicentric RIRSearch study group.

Purpose: Postoperative fever (POF)/urinary tract infection (UTI) is one of the most unpleasant and undesirable conditions for surgeons after retrograde intrarenal surgery (RIRS). RIRS is not recommended for any patient with a positive urine culture to avoid POF and UTI, but some patients may develop postoperative UTI even if the urine culture is sterile. This study investigated the predictive factors of fever and UTIs after RIRS.

Large-scale multi-center CT and MRI segmentation of pancreas with deep learning.

Automated volumetric segmentation of the pancreas on cross-sectional imaging is needed for diagnosis and follow-up of pancreatic diseases. While CT-based pancreatic segmentation is more established, MRI-based segmentation methods are understudied, largely due to a lack of publicly available datasets, benchmarking research efforts, and domain-specific deep learning methods. In this retrospective study, we collected a large dataset (767 scans from 499 participants) of T1-weighted (T1 W) and T2-weighted (T2 W) abdominal MRI series from five centers between March 2004 and November 2022.

The impact of preoperative ureteral stent duration on retrograde intrarenal surgery results: a RIRSearch group study.

A JJ stent placed before retrograde intrarenal surgery (RIRS) may ease the procedure. However, it is important to note that a prolonged duration of double J stent (DJS) placement before RIRS may increase the risk of postoperative urinary tract infection (UTI). Various publications have established this association, although the duration of the DJS before surgery is scarce.

Alterations in microbiome associated with acute pancreatitis.

Purpose Of Review: This review evaluates the current knowledge of gut microbiome alterations in acute pancreatitis, including those that can increase acute pancreatitis risk or worsen disease severity, and the mechanisms of gut microbiome driven injury in acute pancreatitis.

Recent Findings: Recent observational studies in humans showed the association of gut microbiome changes (decreased gut microbiome diversity, alterations in relative abundances of certain species, and association of unique species with functional pathways) with acute pancreatitis risk and severity. Furthermore, in-vivo studies highlighted the role of gut microbiome in the development and severity of acute pancreatitis using FMT models.

Histological Remission of Eosinophilic Esophagitis Following Allogeneic Hematopoietic Stem Cell Transplantation for Acute Myelogenous Leukemia.

Eosinophilic esophagitis (EoE) is an immune/antigen-mediated disease with an increasing incidence over the last decade. Clinicopathological remission can be achieved through different treatment options but often requires chronic therapy. To our knowledge, this is the first report of EoE wherein the patient (a 54-year-old man) achieved histological remission after allogeneic hematopoietic stem cell transplantation (HSCT) for acute myelogenous leukemia.

Diagnosis and Management of Acute Pancreatitis.

Acute pancreatitis (AP) is increasing in incidence across the world, and in all age groups. Major changes in management have occurred in the last decade. Avoiding total parenteral nutrition and prophylactic antibiotics, avoiding overly aggressive fluid resuscitation, initiating early feeding, avoiding endoscopic retrograde cholangiopancreatography in the absence of concomitant cholangitis, same-admission cholecystectomy, and minimally invasive approaches to infected necrosis should now be standard of care.

The Effect of Reusable Flexible Ureteroscope Aging on the Efficacy and Safety of Retrograde Intrarenal Surgery.

Reusable flexible ureteroscopes may lose their mechanical functionality through overuse, which is known as "aging of the flexible ureteroscope." Although mechanical deterioration has been shown in several studies, the data about the effect of this situation on the efficacy and safety of retrograde intrarenal surgery (RIRS) are missing. The aim of our study was to evaluate the effect of the aging of flexible ureteroscopes on the efficacy and safety of RIRS.

The Systemic Immune-Inflammation Index Predicts In-Hospital Mortality in Patients Who Underwent On-Pump Cardiac Surgery.

Background: Systemic immune-inflammation index (SII), a new inflammatory index calculated using platelet, neutrophil, and lymphocyte counts, has been demonstrated to be an independent risk factor for the identification of high-risk coronary artery disease in patients undergoing percutaneous coronary intervention and cardiovascular surgery with cardiopulmonary bypass (CPB). The relationship between SII and CPB-related mortality rates remains unclear.

Objective: This research was designed to investigate the use of SII to predict in-hospital mortality in patients undergoing cardiac surgery with CPB.
