The effects of short-term alpha-ketoisocaproic acid supplementation on exercise performance: a randomized controlled trial
Dietary Supplements and Sports Performance: Herbals
This is the fourth in a series of six articles to discuss the major classes of dietary supplements (vitamins; minerals; amino acids; herbs or botanicals; metabolites, constituents/extracts, or combinations). The major focus is on efficacy of such dietary supplements to enhance exercise or sport performance
The SARS-CoV-2 Alpha variant was associated with increased clinical severity of COVID-19 in Scotland: A genomics-based retrospective cohort analysis
Objectives
The SARS-CoV-2 Alpha variant was associated with increased transmission relative to other variants present at the time of its emergence and several studies have shown an association between Alpha variant infection and increased hospitalisation and 28-day mortality. However, none have addressed the impact on maximum severity of illness in the general population classified by the level of respiratory support required, or death. We aimed to do this.
Methods
In this retrospective multi-centre clinical cohort sub-study of the COG-UK consortium, 1475 samples from Scottish hospitalised and community cases collected between 1st November 2020 and 30th January 2021 were sequenced. We matched sequence data to clinical outcomes as the Alpha variant became dominant in Scotland and modelled the association between Alpha variant infection and severe disease using a 4-point scale of maximum severity by 28 days: 1. no respiratory support, 2. supplemental oxygen, 3. ventilation and 4. death.
Results
Our cumulative generalised linear mixed model analyses found evidence (cumulative odds ratio: 1.40, 95% CI: 1.02, 1.93) of a positive association between increased clinical severity and lineage (Alpha variant versus pre-Alpha variants).
Conclusions
The Alpha variant was associated with more severe clinical disease in the Scottish population than co-circulating lineages

Acute cardiovascular response to resistance training during cardiac rehabilitation: effect of repetition speed and rest periods.
Resistance training has been introduced into rehabilitation to improve the efficiency of the 1980s traditional training. Among the modalities, the choice of recovery period length or repetition speed is hardly explained in term of functional benefit but not in terms of cardiovascular (CV) response. To our knowledge, no investigation has been made on the acute CV effect of repetition speed and rest periods between sets of such training during rehabilitation.Journal ArticleRandomized Controlled TrialSCOPUS: ar.jinfo:eu-repo/semantics/publishe
