Living kidney donation from people at risk of nephrolithiasis, with a focus on the genetic forms.

Urolithiasis 2018 Nov 23. Epub 2018 Nov 23.

UOC Nefrologia, Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome, Italy.

Deciding whether to accept a donor with nephrolithiasis is a multifaceted task because of the challenge of finding enough suitable donors while at the same time ensuring the safety of both donors and recipients. Until not long ago, donors with a history of renal stones or with stones emerging during screening on imaging were not considered ideal, but recent guidelines have adopted less stringent criteria for potential donors at risk of stones. This review goes through the problems that need to be approached to arrive at a wise clinical decision, balancing the safety of donors and recipients with the need to expand the organ pool.

Cardiovascular and non-cardiovascular concerns with proton pump inhibitors: Are they safe?

Trends Cardiovasc Med 2018 Oct 21. Epub 2018 Oct 21.

Italian National Research Center on Aging (IRCCS INRCA), Ancona, Cosenza, Italy.

The introduction of proton pump inhibitors (PPIs) has been a cornerstone in the treatment of acid-related disorders, such as gastroesophageal reflux and peptic ulcer, and their use has increased rapidly during the last decades. Being highly lipophilic drugs, they may potentially affect several pathophysiological pathways involved in cardiovascular and kidney morbidity, immune response and infections, absorption of selected nutrients, bone metabolism and cognitive function. Clinical epidemiology evidence coming from well-designed analyses of observational data consistently reported that long-term use of PPIs may increase the risk of cardiovascular events among patients treated with thienopyridines, tubular-interstitial nephritis and chronic kidney disease, hypomagnesemia, and fractures.

U.O.C. Oncologia, "S. Giovanni di Dio" Hospital, ASLNA2NORD Frattamaggiore, Frattamaggiore, Italy.

Objectives: This study evaluates maintenance cetuximab administered every 2 weeks (q2w) after chemotherapy plus cetuximab as first-line treatment in a series of patients with head and neck squamous cell cancer and compares the results with those obtained in a historical control group of patients receiving weekly cetuximab.

Methods: After chemotherapy plus cetuximab as first-line treatment, in Group A, 36 patients enrolled from October 2016 to November 2017, received biweekly cetuximab, administered at 500 mg/m2. Group B was a control group of patients treated at our institution from August 2015 to September 2016 and received weekly infusion of cetuximab at 250 mg/m2. Read More

Renal Mg handling, FXYD2 and the central role of the Na,K-ATPase.

Physiol Rep 2018 Sep;6(17):e13843

Department of Biomolecular Sciences, Weizmann Institute of Science, Rehovoth, Israel.

This article examines the central role of Na,K-ATPase (α1β1FXYD2) in renal Mg handling, especially in distal convoluted tubule (DCT), the segment responsible for final regulation of Mg balance. By considering effects of Na,K-ATPase on intracellular Na and K concentrations, and driving forces for Mg transport, we propose a consistent rationale explaining basal Mg reabsorption in DCT and altered Mg reabsorption in some human diseases. FXYD2 (γ subunit) is a regulatory subunit that adapts functional properties of Na,K-ATPase to cellular requirements. Read More
