Sedentary Behavior: A Key Component in the Interaction between an Integrated Lifestyle Approach and Cardiac Autonomic Function in Active Young Men.

This study aimed to verify the association between autonomic cardiac function (CAF) and the integration of caloric expenditure by physical activity (PA) intensity, sedentary behavior (SB), and sleep quality (PSQI) in active young men. Thirty-five subjects were included, and caloric expenditure in moderate-to-vigorous and light-intensity PA, SB, and PSQI were assessed using questionnaires. Heart rate variability (HRV) was recorded for short periods of time in the supine and orthostatic positions. Multiple linear regression was realized unadjusted and adjusted for covariables, such as age, body mass index, and fat mass. No adjusted analysis indicated that, in the supine position, there were negative associations between the SB and the TP, HF, and NorHF indices, and positive associations between SB and NorLF and LF/HF. In the orthostatic position, an interaction between SB and NorLF was found. Significance of proportion with the TP, HF, and LF/HF indices was confirmed. When adjusted, for the supine position, negative interactions were documented between SB and the TP as well as the HF indices, and between PSQI and the LF/HF index, with interference under the HF and LF/HF indices. Finally, our findings indicate that the proposed approach interacts with CAF, and SB is significantly related to CAF in young active men.

Antimicrobial properties of the mushroom Agaricus blazei – integrative review

ABSTRACT Infectious diseases associated with antimicrobial resistance are considered to represent an important public health problem. In this regard, the mushroom Agaricus blazei Murrill contains several bioactive substances that promote significant functional properties, among them, antimicrobial activity, which has attracted the interest of the scientific community. Thus, the aim of this study was to determine whether evidence of the antimicrobial action of A. blazei has been reported in the literature. In this integrative review, manuscripts held in research databases available online were examined with a view to answering the question “Does the mushroom A. blazei exert antimicrobial activity against Gram-negative and/or Gram-positive bacteria?” Only eight scientific articles that have addressed the antimicrobial properties of A. blazei, in vitro and in vivo, were found, all characterized as pre-clinical, i.e., with level VII evidence. Most authors have found that the A. blazei extract promotes an antimicrobial effect against peritonitis, as well as deadly oral infections, especially those caused by Gram-positive bacteria. However, the scientific data currently available are not sufficient to verify the antimicrobial aspect of the mushroom A. blazei and thus further investigation is required.
