Self-perceived physical fitness and occurrences of individual levels of autistic traits in adolescents: a cluster association study.

Background: The association between physical fitness and autistic traits in adolescents remains under explored, especially in adolescents. Understanding this relationship can provide strategies to improve the quality of life of these people.

Objective: To identify the association between cluster characteristics derived from levels of self-perceived physical fitness and the occurrences of individual levels of autistic traits in Brazilian adolescents.

Long-Term Efficacy and Safety of Danicopan as Add-On Therapy to Ravulizumab or Eculizumab in PNH With Significant EVH.

Complement C5 inhibitor treatment with ravulizumab or eculizumab for paroxysmal nocturnal hemoglobinuria (PNH) improves outcomes and survival. Some patients remain anemic due to clinically significant extravascular hemolysis (cs-EVH: hemoglobin [Hgb] ≤9.5 g/dL and absolute reticulocyte count [ARC] ≥120×109/L).

Impact of donor pool size on the variability of platelet lysate-derived extracellular vesicles for regenerative medicine.

The objective of the present study was to determine the variability of platelet lysate-derived extracellular vesicles (pEV), in terms of characteristics and functionality through wound healing assays, when isolated either from platelet concentrates (PC, obtained from 5 donors) or from multiple PC (MPC, that is 50 donors). pEV were isolated under GMP-like conditions in a clean room using Size Exclusion Chromatography (SEC). The differential characteristics between pEV obtained from PC (PC-EV) or MPC (MPC-EV) were evaluated by means of protein concentration, Nanoparticle Tracking Analysis (NTA), Transmission Electron Microscopy (TEM), and flow cytometry using the MACSPlex™ arrays for surface analysis profiling of EV.

Instruments for evaluating parental support for the practice of physical activity in children and adolescents: A scoping review.

Objective: The objective of this study was to map the instruments used to assess parental support for physical activity and their constructs and psychometric properties.

Data Source: A scoping review was conducted, with searches in seven electronic databases and reference lists, covering articles available until April 2022. Original and cross-sectional studies were sought that used questionnaires, inventories or questions to assess parental support for the practice of physical activity and sports by children and adolescents aged 6 to 17 years and that assessed the barriers reported by parents or guardians for not offering support.

Getting up for brain health: Association of sedentary behavior breaks with cognition and mental health in children.

Children spend most of their waking hours sedentary and reducing this behavior has been challenging. Interrupting prolonged episodes of sedentary behavior with active breaks can provide mental and cognitive health benefits. Considering the multifactorial nature of these health aspects, this study aimed to verify the role of body mass index (BMI), cardiorespiratory fitness (CRF), and moderate to vigorous physical activity (MVPA) in the relationship between the break in sedentary time with cognitive and mental health in children.
