Main Body: Cultural context is an important aspect to consider in this skill, as it tends to modulate the recognition of facial expressions.
Objective: To develop and validate a set of facial expressions of basic emotions of Brazilian individuals considering the population distribution of the country according to age group, sex, and race.
Background And Purpose: Resistance training exercise provides increases in muscle size and is used by coaches and health care professional as a tool to improve functional performance. The aim of the present study was to investigate the effect of 10 weeks of resistance training program performed on the bench press (BP) exercise on the hypertrophic responses of four different muscles (pectoralis major, anterior and medial deltoid, brachii, and pectoralis minor) involved in the task compared to controls.
Methods: Twenty-four healthy males were recruited, and thirteen performed a resistance training intervention while eleven were control.
Importance: Test accuracy studies often use small datasets to simultaneously select an optimal cutoff score that maximizes test accuracy and generate accuracy estimates.
Objective: To evaluate the degree to which using data-driven methods to simultaneously select an optimal Patient Health Questionnaire-9 (PHQ-9) cutoff score and estimate accuracy yields (1) optimal cutoff scores that differ from the population-level optimal cutoff score and (2) biased accuracy estimates.
Design, Setting, And Participants: This study used cross-sectional data from an existing individual participant data meta-analysis (IPDMA) database on PHQ-9 screening accuracy to represent a hypothetical population.
Article Synopsis
- - The study explores the effectiveness of remote tele-mentored ultrasound (RTMUS) in diagnosing pulmonary conditions in ICUs, comparing it to point-of-care ultrasound (POCUS), specifically for diagnosing pulmonary oedema, pneumonia, and COPD.
- - Conducted in three adult ICUs with 23 patients, the results showed RTMUS had good accuracy for COPD (89.96%) and reasonable levels for pulmonary oedema (71.43%), but performed less effectively for pneumonia (65.22%).
- - The findings suggest RTMUS could be a viable alternative to POCUS for certain conditions, but the authors caution that further studies with larger sample sizes are needed to confirm these results.
