The Safety of Multiple-Dose Liquid Blend Containing Kava and Kratom in Healthy Adults.

This study investigates the safety of three different daily dosages of a liquid blend containing kava and kratom (Feel Free® Classic Tonic {FFCT}) in healthy adults over six consecutive days of supplementation. Both kava and kratom have been used traditionally for hundreds of years, but there is limited data on the combined safety of these ingredients. In this randomized, double-blind, placebo-controlled trial, the participants were assigned to receive one of three daily dosages of FFCT or placebo.

Surgical technique of minor revision of a transcutaneous osseointegration prosthetic system (TOPS) with implant retention.

Objective: Transcutaneous osseointegration prosthetic systems (TOPS) offer a stable skeletal attachment for artificial limbs post-extremity amputation, serving as an alternative to socket attachment. Press-fit osseointegration implants (OI) utilized in TOPS consistently enhance quality of life and mobility for amputees, particularly those experiencing socket-related issues. Despite notable benefits, late complications such as infection and implant loosening pose challenges unique to TOPS due to their percutaneous nature.

Succinate Regulates Endothelial Mitochondrial Function and Barrier Integrity.

Endothelial dysfunction is a hallmark of several pathological conditions, including cancer, cardiovascular disease and inflammatory disorders. In these conditions, perturbed TCA cycle and subsequent succinate accumulation have been reported. The role of succinate as a regulator of immunological responses and inflammation is increasingly being recognized.

Revision of Press-Fit Bone-Anchored Prosthesis After Implant Failure.

Background: The present video article describes the revision of a bone-anchored prosthesis in patients who received an osseointegration implant after transfemoral amputation. Clinical follow-up studies have shown that approximately 5% of all patients who receive press-fit cobalt-chromium alloy femoral implants experience failure of the intramedullary stem component as a result of septic loosening or stem breakage. For stem breakage, stem diameter and the occurrence of infectious events were identified as risk factors.

Describing Clinical Nurse Specialist Practice: A Mixed-Methods Study.

Purpose/aims: To describe clinical nurse specialist practice in Québec, Canada, and propose a dashboard to track role dimensions and outcomes.

Design: Sequential mixed-methods study across 6 sites in Québec (June 2021 to May 2022).

Methods: Phase 1: Focus groups (n = 8) and individual interviews (n = 3) were conducted to adapt a time and motion tool.
