The aim of the current study was to investigate the effects of ingesting different dosages of caffeine (CAF) prior to plyometric jump training (PJT) on sport-related performance and physiological parameters in male basketball players. Twenty-four young athletes were randomly divided into 3 groups and performed 6 weeks of PJT while consuming 3 mg·kg of body mass caffeine (CAF3, n = 8), 6 mg·kg body mass caffeine (CAF6, n = 8) or placebo (PL; n = 8) one hour prior to each training session. Before and after the 6-week PJT, the players were evaluated for field-based basketball-specific performance measures (vertical jump, 20-m sprint, Illinois change of direction speed [CODS], and maximal strength) and lab-based physiological (aerobic capacity and anaerobic power) parameters. CAF3, CAF6, and PL groups demonstrated significant improvements in vertical jump (ES = 1.07, 1.45, and 1.1, respectively), 20-m sprint (ES = - 0.50, - 0.61, and - 0.36), change of direction performance (ES = - 1.22, - 1.26, and - 1.09), maximal strength (ES = 1.68, 2.29, and 1.17), maximum oxygen uptake (V̇O) (ES = 1.09, 1.59, and 0.92), and peak (ES = 1.82, 1.85, and 0.82) and average power output (ES = 1.39, 1.32, and 1.07) after 6 weeks of training. Comparative analysis of individual adaptive responses to training indicated that the CAF6 led to insignificantly greater effects in vertical jump (ES = 1.45), maximal strength (ES = 2.29), and V̇O (ES = 1.59) with lower residuals in individual changes and lower coefficient of variations (CV) in mean group changes. Regarding sprint and CODS performance, both experimental groups indicated similar changes, residuals in individual changes, and CVs in mean group changes. Overall, consuming 6 mg·kg body mass caffeine induces superior adaptations in aerobic fitness, anaerobic power, and sport-specific performance measures, with lower inter-individual variability in the adaptations and more homogenized changes over the training period.

Ultrasound evaluation of gastric emptying for two different quantities of milk in elementary school-aged children.

Department of Anesthesiology, Children's Hospital Affiliated to Shandong University & Jinan Children's Hospital, No. 23976, Jingshi Road, Jinan, 250012, China.
Unlabelled: Current guidelines recommend 6-h milk fasting in periprocedural settings; however, recent evidence suggests potential overconservativeness and supports more liberal pediatric fasting protocols. This study assessed the gastric emptying of two different milk quantities in elementary school-age children using gastric ultrasonography. This prospective crossover trial involved 30 healthy children who fasted overnight on two separate occasions within one month, consuming either 5 or 10 mL/kg of milk.

Objectives: Understanding the epidemiology of treatment for patients with co-occurring depression and obesity can inform care quality. The objective of the study was to identify how patients with obesity and newly diagnosed depression are treated and whether treatment is associated with body mass index change.
Methods: This cohort study included adults with obesity and newly diagnosed depression who had ≥2 primary care visits between 2015 and 2020 at a large integrated health system.
ICU-Broncho-Aspiration Protocols Monitoring at an Academic Health Network System.

Objectives: The objectives were to determine intensive care unit (ICU) incidence of broncho-aspiration (BA) and the effect of monitoring BA prevention protocols.
Methods: The Health Network Warehouse was interrogated for the diagnosis of BA in patients older than 18 years in the surgical ICU (SICU) from January 2010 to December 2020. A BA prevention bundle protocol was prospectively monitored during all consecutive SICU admissions from August 2021 to November 2021 until discharge/death (n = 159).
Alpelisib is a phosphatidylinositol 3-kinase inhibitor approved by the US Food and Drug Administration for the treatment of hormone receptor-positive metastatic breast cancer with (phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit α) mutation. In recent years a number of adverse effects have been observed to be associated with this therapy, the most notable of which is hyperglycemia. A literature search was conducted to include case studies, case series, systematic reviews, and meta-analyses within the last 10 years that evaluated patients with mutated hormone receptor-positive, human epidermal growth factor receptor 2 negative metastatic breast cancer.
