Enhancing beer authentication, quality, and control assessment using non-invasive spectroscopy through bottle and machine learning modeling.

Fraud in alcoholic beverages through counterfeiting and adulteration is rising, significantly impacting companies economically. This study aimed to develop a method using near-infrared (NIR) spectroscopy (1596-2396 nm) through the bottle, along with machine learning (ML) modeling for beer authentication, quality traits, and control assessment. For this study, 25 commercial beers from different brands, styles, and three types of fermentation were used.

Prospective Harmonization, Common Data Elements, and Sharing Strategies for Multicenter Pre-Clinical Traumatic Brain Injury Research in the Translational Outcomes Project in Neurotrauma Consortium.

Effective team science requires procedural harmonization for rigor and reproducibility. Multicenter studies across experimental modalities (domains) can help accelerate translation. The Translational Outcomes Project in NeuroTrauma (TOP-NT) is a pre-clinical traumatic brain injury (TBI) consortium charged with establishing and validating noninvasive TBI assessment tools through team science.

Association of Step Count with Cardiorespiratory Fitness: Results from the Virtual 2-Minute Step Test.

Objective: To test the hypothesis that step count based on a virtual 2-minute step test (2MST) predicts cardiorespiratory fitness (CRF).

Design: Cross-sectional study.

Setting: Veteran Affairs Medical Centers participating in a randomized trial of functional exercise training delivered by videoconferencing.

The gut-lung axis: Protozoa join the party.

The gut microbiota is a powerful influencer of systemic immunity, with its impact on distal organs like the lungs garnering increasing attention. In this issue of Cell, Burrows et al. report that a gut protozoan plays a key role in shaping the immunological steady state of the lung.

Reducing medical cannabis use risk among Veterans: A descriptive study.

Background: Canadian Veterans experiencing chronic pain report concerns about accessing accurate information on the risks associated with medical cannabis (MC) use. The Lower Risk Cannabis Use Guidelines (LRCUG) were developed to equip individuals who use cannabis recreationally with safer-use strategies. Many of the harm reduction recommendations for recreational cannabis use are relevant and important considerations for MC use.
