Experimental bilayer zirconia systems after aging: Mechanical, optical, and microstructural characterization.

Objectives: To characterize two experimental zirconia bilayer materials compared to their monolithic controls, before and after hydrothermal aging.

Methods: Commercial zirconia powders were utilized to fabricate two bilayer materials: 3Y-TZP+ 5Y-PSZ (3Y+5Y/BI) and 4Y-PSZ+ 5Y-PSZ (4Y+5Y/BI), alongside control groups 3Y-TZP (3Y/C), 4Y-PSZ (4Y/C), and 5Y-PSZ (5Y/C). Compacted specimens were sintered (1550 °C- 2 h, 3 °C/min), and half of them underwent hydrothermal aging (134 °C-20h, 2.

Identifying biomarker-driven subphenotypes of cardiogenic shock: analysis of prospective cohorts and randomized controlled trials.

Background: Cardiogenic shock (CS) is a heterogeneous clinical syndrome, making it challenging to predict patient trajectory and response to treatment. This study aims to identify biological/molecular CS subphenotypes, evaluate their association with outcome, and explore their impact on heterogeneity of treatment effect (ShockCO-OP, NCT06376318).

Methods: We used unsupervised clustering to integrate plasma biomarker data from two prospective cohorts of CS patients: CardShock (N = 205 [2010-2012, NCT01374867]) and the French and European Outcome reGistry in Intensive Care Units (FROG-ICU) (N = 228 [2011-2013, NCT01367093]) to determine the optimal number of classes.

Effects of a 12-Week Physical Activity Intervention on Psychological Symptoms in Adolescents.

Participation in regular physical activity (PA) is associated with numerous health benefits, including improvement in adolescents' mental health. The current study aimed to assess the effects of a 12-week physical activity intervention on psychological symptoms of adolescents. The sample of this controlled randomized study was composed by 150 adolescents aged 12 to 15 years old.

A Longitudinal Study of Vocal Symptomatology in Teachers During Distance, Hybrid, and In-Person Teaching.

Objective: To compare the vocal symptomatology of professors from a federal university who engaged in distance, hybrid, and face-to-face teaching during and after the Coronavirus Disease 2019 (COVID-19) pandemic period.

Method: The study included 40 university professors, 20 men and 20 women, whose symptomatology was monitored at three time points: during the distance teaching period due to social isolation caused by COVID-19, in hybrid teaching (partial return), and upon returning to face-to-face teaching, which required the use of face masks and posed contamination risks.

Results: The hybrid phase presented the highest absence of vocal complaints/discomfort, and most participants did not need to be reassigned due to vocal problems.

Association of Evening Eating with Sleep Quality and Insomnia among Adults in a Brazilian National Survey.

 To examine the association of evening eating clock time, its elapsed time to the midpoint of sleep (TEM), consumption of caffeine and sugary foods, and reporting dinner as the largest meal with sleep quality indicators and insomnia.  Participants (  = 2,050;18-65y) were part of population-based research, with virtual data collection. Logistic regression models were fitted to assess differences in the ORs(95%CI) of sleep duration < 7 hours, sleep latency > 30 minutes, poor sleep quality, and insomnia (outcomes) with the evening diet-related variables.
