Recent advances in pathophysiology, diagnosis and management of hepatorenal syndrome: A review.

Hepatorenal syndrome with acute kidney injury (HRS-AKI) is a form of rapidly progressive kidney dysfunction in patients with decompensated cirrhosis and/or acute severe liver injury such as acute liver failure. Current data suggest that HRS-AKI occurs secondary to circulatory dysfunction characterized by marked splanchnic vasodilation, leading to reduction of effective arterial blood volume and glomerular filtration rate. Thus, volume expansion and splanchnic vasoconstriction constitute the mainstay of medical therapy.

Advances in the management of cholangiocarcinoma.

Cholangiocarcinoma (CCA) is a primary malignancy of the bile ducts with three anatomically and molecularly distinct entities: Intrahepatic CCA (iCCA), perihilar CCA (pCCA), and distal CCA. As a result of phenotypic and anatomic differences they differ significantly with respect to management. For each type of CCA there have been significant changes in management over the last several years which will be discussed in this review.

Adaptive staffing can mitigate essential worker disease and absenteeism in an emerging epidemic.

Essential worker absenteeism has been a pressing problem in the COVID-19 pandemic. Nearly 20% of US hospitals experienced staff shortages, exhausting replacement pools and at times requiring COVID-positive healthcare workers to remain at work. To our knowledge there are no data-informed models examining how different staffing strategies affect epidemic dynamics on a network in the context of rising worker absenteeism.

Standardized approach of albumin, midodrine and octreotide on hepatorenal syndrome treatment response rate.

Background: Hepatorenal syndrome (HRS) remains a serious complication of cirrhosis with a high mortality rate. There is little information on the effect of standardizing albumin, midodrine and octreotide combination on treatment response in patients with HRS.

Objective: The aim of the study was to determine the impact of a standardized HRS treatment regimen on renal function recovery.

Favorable Survival with Non-curative Treatments for Patients with Early-Stage Hepatocellular Carcinoma After Liver Transplant Denial.

Background: Many patients are not candidates for liver transplant for non-tumor-related reasons including medical comorbidities and non-adherence. The prognosis of patients with hepatocellular carcinoma (HCC) who are not liver transplant candidates in the era of locoregional therapy (LRT) including y90 is not well defined.

Aims: This study seeks to evaluate outcomes and the natural history of early-stage HCC in patients who were denied liver transplant listing due to non-tumor reasons and instead were treated with LRT.

Locoregional Therapy Protocols With and Without Radioembolization for Hepatocellular Carcinoma as Bridge to Liver Transplantation.

Objective: The objective of this study was to compare posttransplant outcomes in patients undergoing bridging locoregional therapy (LRT) with Y-90 transarterial radioembolization (TARE) based protocol compared with transarterial chemoembolization based protocol for hepatocellular carcinoma (HCC) prior liver transplantation (LT).

Materials And Methods: Patients listed for LT with HCC within the Milan criteria at our center who had bridging LRT were treated according to transarterial chemoembolization (TACE) based protocol from May 2012 to April 2014 and a TARE based protocol from October 2014 to December 2017. Early posttransplant survival and tumor recurrence were compared between the groups.

Malignant Peritoneal Mesothelioma Presenting as Mucinous Ascites.

We present a rare case of a 46-year-old man presenting with mucinous ascites secondary to malignant peritoneal mesothelioma (MPM) that was diagnosed via colonoscopy with biopsies. Both our findings and the clinical presentation were unique. While it is widely known that asbestos exposure is commonly associated with pleural mesothelioma, 6-10% of malignant mesotheliomas arise from the peritoneum.

Utility of clinical suspicion and endoscopic re-examination for detection of esophagogastric perforation after pneumatic dilation for achalasia.

Background And Study Aims: Esophagrams are often obtained routinely after pneumatic balloon dilation for achalasia, even in asymptomatic patients, as there is a risk of postprocedure esophagogastric perforation, which is a potentially life-threatening complication. The aim of this study was to determine whether the combination of a clinical suspicion of perforation and endoscopic re-examination after pneumatic dilation for achalasia can detect esophagogastric perforation, and thereby preclude the need for routine esophagrams in all patients.

Patients And Methods: All patients who underwent pneumatic dilation between January 2002 and June 2012 at our single tertiary referral center were identified retrospectively.

PKU is a reversible neurodegenerative process within the nigrostriatum that begins as early as 4 weeks of age in Pah(enu2) mice.

Phenylketonuria (PKU) is a common genetic disorder in humans that arises from deficient activity of phenylalanine hydroxylase (PAH), which catalyzes the conversion of phenylalanine to tyrosine. There is a resultant hyperphenylalanemia with subsequent impairment in cognitive abilities, executive functions and motor coordination. The neuropathogenesis of the disease has not been completely elucidated, however, oxidative stress is considered to be a key feature of the disease process.
