This umbrella meta-analysis aims to investigate two surgical treatments for abdominal aortic aneurysm (AAA): endovascular aneurysm repair (EVAR) and open surgery repair (OSR). Our study aims to elucidate the 30-day mortality rate, reintervention rates, and aneurysm-related mortality in EVAR versus OSR for AAA.  We conducted a comprehensive assessment of meta-analyses ( = 34 articles) comparing EVAR and OSR for AAA.

Introduction: Extrapulmonary tuberculosis (EPTB) adds to India's significant economic burden, with pericardial effusion being a potentially fatal complication. This case report highlights the need for early diagnosis and the feasibility of shorter-duration treatment for EPTB in developing countries.

Presentation: This case report describes a 19-year-old male from Southeast Asia who had a history of bronchiectasis involving the left lower lobe and the right middle lobe, which was cystic in nature, as well as multiple episodes of non-tuberculous pneumonia.

Hepatocellular carcinoma (HCC) is a primary liver malignancy, ranking as the seventh most common cancer globally and the second leading cause of deaths due to cancer. This review examines the incidence of HCC, its associated risk factors, and constantly changing global trends. Incidence has been noted to be varying worldwide, particularly due to environmental and infectious risk factors.

Background/aims: In patients undergoing endoscopic retrograde cholangiopancreatography (ERCP), calcineurin activates zymogen, which results in pancreatitis. In this study, we aimed to determine the efficacy of tacrolimus, a calcineurin inhibitor, in preventing post-ERCP pancreatitis (PEP).

Methods: This was a prospective pilot study in which patients who underwent ERCP received tacrolimus (4 mg in two divided doses); this was the Tac group.

Background: Intra-abdominal lymphadenopathy due to tuberculosis (TB) poses a diagnostic challenge due to difficulty in tissue acquisition. Although endoscopic ultrasound guided fine needle aspiration/biopsy (EUS-FNA/B) has shown promise in the evaluation of mediastinal lymph nodes, its role in the evaluation of intra-abdominal lymphadenopathy is not clear.

Aim: To assess the role of EUS-FNA/B in the evaluation of intra-abdominal lymphadenopathy due to TB.

Introduction: Systemic inflammation triggered by bacterial products like lipopolysaccharides (LPS) in the circulation is an important factor leading to decompensation in patients with chronic liver disease (CLD). High-density lipoprotein cholesterol (HDL-C) has a significant role in innate immune response to LPS in the circulation and could therefore increase the risk for decompensation in patients with CLD. In this study, we have explored the role of HDL-C as a prognostic marker for decompensation.

Background: Biliary strictures following living donor liver transplantation (LDLT) are usually managed by endoscopic retrograde cholangiography (ERC) with stricture dilation and stent placement. While current endoscopic techniques are successful in most cases, high-grade biliary strictures (HGBS) pose a challenge using currently employed techniques which have a low rate of technical success.

Aims: In this study, we have explored the safety and efficacy of Soehendra stent retrievers (SSR) for the dilation of HGBS complicating LDLT.

Fungi in the genus are widespread and destructive pathogens of grasses worldwide, and are best known as the causal agents of dollar spot disease in turfgrass. Here, we report genome assemblies of seven isolates, including ex-types of the two most widespread species, and . These datasets provide a valuable resource for ongoing studies of the dollar spot pathogens that include population diversity, host-pathogen interactions, marker development, and disease control.

Aim: Validation of new metrics to identify functionally significant obstruction (FSO), to better define biliary strictures complicating living donor liver transplantation (LDLT).

Methods: All LDLT recipients who presented with cholestasis were studied. Novel metrics for FSO are as follows: (1) magnetic resonance cholangiopancreatography (MRCP) ductal ratio (MDR): The ratio between hepatic duct and recipient duct diameter on the MRCP taken at presentation; (2) endoscopic retrograde cholangiography (ERC) ductal ratio (EDR): The ratio between hepatic duct and recipient duct diameter on the first ERC done for suspected biliary strictures; (3) delayed contrast drainage (DCD): > 50% contrast retained above the anastomotic site, in more than three consecutive fluoroscopic images taken at least 15 min after contrast instillation.

Background: Relative adrenal insufficiency (RAI) is common in compensated and decompensated chronic liver disease in the presence of sepsis. This study was performed to find out the prevalence of RAI in decompensated cirrhotic patients presenting with hepatic encephalopathy and variceal bleeding without any evidence of infection.

Methods: The study prospectively included 75 cirrhotic patients with signs of decompensation.

Introduction: Chronic calcific pancreatitis (CCP) is a major risk factor for pancreatic ductal adenocarcinoma (PDAC) and is common in southern India. Endoscopic ultrasound fine-needle aspiration (EUS-FNA) is useful for tissue acquisition in patients with solid pancreatic lesions. Multiple factors may affect the diagnostic yield of FNA samples.

Pancreatic duct (PD) leak leading to pancreatic ascites is a serious complication of chronic pancreatitis. Endoscopic management with endoscopic retrograde cholangiopancreatography (ERCP) has been found to be successful; however, if selective cannulation of the PD is unsuccessful, an endoscopic ultrasound-guided rendezvous procedure can help in bridging PD leaks, provided the duct is dilated. We report a successful endoscopic ultrasound-guided rendezvous procedure in a patient with PD leak, pancreatic ascites, and a nondilated duct with failed ERCP who was a poor candidate for surgery.

To understand the role of hyperthermia (HT) in adaptive response, methyl methanesulfonate (MMS) adapted meiotic cells of Poecilocerus pictus were used. Poecilocerus pictus were treated with conditioning (L) or challenging (H) dose of MMS and 2-h time lag (TL) between these doses (L-2h-H) (combined) was employed. Different treatment schedules were used to analyse the influence of HT on MMS-induced adaptive response namely pre; inter; post-treatment and cross-adaptation.

Biliary stricture complicating living donor liver transplantation (LDLT) is a relatively common complication, occurring in most transplant centres across the world. Cases of biliary strictures are more common in LDLT than in deceased donor liver transplantation. Endoscopic management is the mainstay for biliary strictures complicating LDLT and includes endoscopic retrograde cholangiography, sphincterotomy and stent placement (with or without balloon dilatation).

Background: Percutaneous endoscopic gastrostomy (PEG) placement is the modality of choice for long-term enteral nutrition in view of technical ease and cost-effectiveness. Peristomal infection (PI) remains the most common complication following PEG tube placement. The aim of this study was to assess the incidence and risk factors for PI and outline a microbiological profile that can aid in prophylactic and therapeutic strategies.

The utility of green silver nanoparticles (AgNPs) in veterinary medicine is steadily increasing as they have many therapeutic applications against pathogens and arthropods of livestock. In this study, green AgNPs using neem (N-AgNPs), 2,3-dehydrosalanol (2,3-DHS-AgNPs) and quercetin dihydrate (QDH-AgNPs) were synthesised and characterised. Synthesised compounds were characterised by UV-Vis spectroscopy and the peak absorbance was recorded at 370 nm for neem extract.
