Background: Dysbiotic gut bacteria engage in the development and progression of severe alcoholic hepatitis (SAH). We aimed to characterize bacterial communities associated with clinical events (CE), identify significant bacteria linked to CE, and define bacterial relationships associated with specific CE and outcomes at baseline and after treatment in SAH.

Methods: We performed 16-s rRNA sequencing on stool samples (n=38) collected at admission and the last follow-up within 90 days in SAH patients (n=26; 12 corticosteroids; 14 granulocyte colony-stimulating factor, [G-CSF]).

Background: Transjugular intrahepatic portosystemic shunt (TIPS) placement improves survival in patients with refractory/recurrent acute variceal bleeding (RAVB) and refractory ascites/hydrothorax. Recently, early TIPS was shown to reduce rebleeding and improve survival compared to the conventional TIPS. We aimed to study outcomes in patients with cirrhosis undergoing TIPS at first significant portal hypertensive (PHT) decompensation (termed anticipant TIPS) compared to those undergoing TIPS for recurrent or persistent PHT complications (conventional) and compared the former to matched controls on standard medical management (SMT).

Gastric varices are encountered less frequently than esophageal varices. Nonetheless, gastric variceal bleeding is more severe and associated with worse outcomes. Conventionally, gastric varices have been described based on the location and extent and endoscopic treatments offered based on these descriptions.

More than five decades after it was originally conceptualized as rescue therapy for patients with intractable variceal bleeding, the transjugular intrahepatic portosystemic shunt (TIPS) procedure continues to remain a focus of intense clinical and biomedical research. By the impressive reduction in portal pressure achieved by this intervention, coupled with its minimally invasive nature, TIPS has gained increasing acceptance in the treatment of complications of portal hypertension. The early years of TIPS were plagued by poor long-term patency of the stents and increased incidence of hepatic encephalopathy.

With growing antipathy toward conventional prescription drugs due to the fear of adverse events, the general and patient populations have been increasingly using complementary and alternative medications (CAMs) for managing acute and chronic diseases. The general misconception is that natural herbal-based preparations are devoid of toxicity, and hence short- and long-term use remain justified among people as well as the CAM practitioners who prescribe these medicines. In this regard, Ayurvedic herbal medications have become one of the most utilized in the East, specifically the Indian sub-continent, with increasing use in the West.

Since the appearance of the novel coronavirus (severe acute respiratory syndrome-coronavirus-2) and related coronavirus disease 2019 (COVID-19) in China in December 2019, a very high number of small and large patient series have been published in literature from around the world. Even though the classical presentation of COVID-19 is one with respiratory symptoms with or without pneumonia that can be self-limiting or evolve into severe respiratory distress syndrome with multiple organ failure, and secondary bacterial sepsis, a large body of evidence suggests a plethora of other types of clinical presentation. In this exhaustive review, we reviewed all of the published literature on COVID-19 to identify different types of clinical presentations affecting various organ systems, to provide an in-depth analysis that may prove useful for clinicians and health-workers on the frontline, battling the severe pandemic.

Sepsis and septic shock are catastrophic disease entities that portend high mortality in patients with cirrhosis. In cirrhosis, hemodynamic perturbations, immune dysregulation, and persistent systemic inflammation with altered gut microbiota in the background of portal hypertension enhance the risk of infections and resistance to antimicrobials. Patients with cirrhosis develop recurrent life-threatening infections that progress to multiple organ failure.

Background: Portosystemic shunts (PSS) are associated with recurrent or persistent hepatic encephalopathy (HE), severe portal hypertensive (PHT) complications, and poor survival in cirrhosis patients. Shunt embolization improves HE in patients with recurrent or persistent HE. The role of early shunt embolization (ESE) in comparison with no and late SE (LSE) in cirrhosis patients with PSS and associated clinical outcomes are not studied.

Background: Synthetic colloids, both starches and gelatins, are commonly used as intravascular fluid replacements on account of increased vascular persistence. The safety on renal outcomes during perioperative use is poorly understood.

Aims: We evaluated renal outcomes of hydroxyethyl starch 6% (HES) and gelatins 4% (G) in patients undergoing elective abdominal surgery.
