Kidney transplantation in human immunodeficiency virus-infected patients: a report of two cases and a review of the literatures.

Human immunodeficiency virus (HIV) infection was traditionally considered an absolute contraindication for transplantation because of concerns about HIV disease progression due to immunosuppression. Since potent antiretroviral therapies (ARTs) have become widely available, the prognosis of HIV-infected kidney transplant recipients has dramatically improved. Recent results of prospective multicenter trials on kidney transplantation (KT) in HIV-positive candidates have demonstrated the success and challenges of transplantation in this population.

Liver Fibrosis Assessment with Diffusion-Weighted Imaging: Value of Liver Apparent Diffusion Coefficient Normalization Using the Spleen as a Reference Organ.

Liver fibrosis staging is of great clinical importance because it is used to assess the severity of the underlying chronic liver disease. Among various imaging-based methods, apparent diffusion coefficient (ADC) measurement using diffusion-weighted imaging (DWI) has the potential to be used as an imaging biomarker for liver fibrosis assessment. In this study, we investigated the usefulness of liver ADC normalization using the spleen as a reference organ in liver fibrosis staging with 66 patients who underwent liver magnetic resonance imaging (MRI), transient elastography (TE), and surgical resection of a hepatic mass.

Adipose sirtuin 6 drives macrophage polarization toward M2 through IL-4 production and maintains systemic insulin sensitivity in mice and humans.

Adipose tissue inflammation is a reproducible feature of obesity and obesity-linked insulin resistance. Although sirtuin 6 (Sirt6) deficiency has previously been implicated in diet-induced obesity and systemic insulin resistance, the adipocyte-specific role of Sirt6 in the regulation of adipose tissue inflammation and systemic metabolic dysfunction in mice fed normal chow and in humans remains elusive. Here, using Adipoq-Cre-mediated adipocyte-specific Sirt6 knockout (aS6KO) mice, we explored whether adipocyte Sirt6 inhibits adipose tissue inflammation and its underlying mechanism.

En-Bloc Pediatric Kidney Transplant to Adult Recipient with Two Different Ureterovesical Anastomosis Techniques.

BACKGROUND En-bloc kidney transplantation from a small pediatric donor to an adult recipient has become more common owing to the shortage of deceased donor kidneys. In pediatric en-bloc kidney transplantation, ureterovesical anastomosis can be done either via ureteroneocystostomy or via partial bladder wall transplantation. We report 2 cases of en bloc kidney transplantation from a pediatric deceased donor to an adult recipient using different ureterovesical anastomosis methods and the long-term outcomes.
