Systemic inhibition of purine biosynthesis prevents weight gain and improves metabolic health by increasing thermogenesis and decreasing food intake.

Objective: Obesity is a major health concern, largely because it contributes to type 2 diabetes mellitus (T2DM), cardiovascular disease, and various malignancies. Increase in circulating amino acids and lipids, in part due to adipose dysfunction, have been shown to drive obesity-mediated diseases. Similarly, elevated purines and uric acid, a degradation product of purine metabolism, are found in the bloodstream and in adipose tissue.

Multidrug-resistant bacterial infections after liver transplantation: Prevalence, impact, and risk factors.

Background & Aims: Infections by multidrug-resistant bacteria (MDRB) are an increasing healthcare problem worldwide. This study analyzes the incidence, burden, and risk factors associated with MDRB infections after liver transplant(ation) (LT).

Methods: This retrospective, multicenter cohort study included adult patients who underwent LT between January 2017 and January 2020.

Utility of the modified 5-item frail index to predict complications and reoperations after hallux valgus percutaneous surgery.

Introduction: The modified 5-item frailty index (mFI-5) has been recently proposed as a useful tool for predicting postoperative complications in orthopedic surgery. We aimed to analyze the utility of this score in predicting complications and reoperations after hallux valgus (HV) deformity surgery.

Methods: 551 patients undergoing percutaneous HV corrective surgery were retrospectively reviewed.

Seasonal riverine inputs may affect diet and mercury bioaccumulation in Arctic coastal zooplankton.

Climate change driven increases in permafrost thaw and terrestrial runoff are expected to facilitate the mobilization and transport of mercury (Hg) from catchment soils to coastal areas in the Arctic, potentially increasing Hg exposure of marine food webs. The main aim of this study was to determine the impacts of seasonal riverine inputs on land-ocean Hg transport, zooplankton diet and Hg bioaccumulation in an Arctic estuary (Adventfjorden, Svalbard). The Adventelva River was a source of dissolved and particulate Hg to Adventfjorden, especially in June and July during the river's main discharge period.
