Systolic time intervals (STI) were measured at rest before and after an exercise training programme in 37 patients with ischemic heart disease; 17 patients were treated with a beta-blocking drug (BB-group) and 20 were not (nBB-group). After the training period peak oxygen uptake had increased by 37% in the BB-patients and by 41% in the nBB-group. During the training period electromechanical systole (QS2) and pre-ejection period (PEP), when corrected for heart rate, shortened significantly in all 37 patients. Left ventricular ejection time (LVET) increased but when corrected for heart rate no significant changes occurred. The ratio of PEP/LVET decreased significantly. The changes in STI were similar in the patients treated with beta-blocking drugs than in those without such treatment. The changes in STI in both groups suggest that left ventricular function improves during the training period and that beta-adrenergic blockade does not alter this outcome.

The psychological impact of pediatric burn injuries is profound, often resulting in elevated levels of anxiety for both children and their mothers. This quasi-experimental study was conducted to explore the effectiveness of a resilience training program aimed at reducing anxiety among mothers and their hospitalized children with burn injuries at a burn hospital in Shiraz, Iran. Fifty-six eligible mothers were initially selected through purposive sampling and assigned to either the experimental or control group in a 1:1 ratio through random assignment.

Background: Resilience refers to the ability to adapt or recover from stress. There is increasing appreciation that it plays an important role in wholistic patient-centered care and may affect patient outcomes, including those of orthopaedic surgery. Despite being a focus of the current orthopaedic evidence, there is no strong understanding yet of whether resilience is a stable patient quality or a dynamic one that may be modified perioperatively to improve patient-reported outcome scores.

Background: Early childhood is a critical period for shaping lifelong health behaviors, making early childhood education and care (ECEC) environments ideal for implementing nutrition and physical activity interventions. eHealth tools are increasingly utilized in ECEC settings due to their accessibility, scalability, and cost-effectiveness, demonstrating promise in enhancing educators' practices. Despite the potential effectiveness of these eHealth approaches, a comprehensive collection of available evidence on eHealth tools designed to assess or support best practices for nutrition or physical activity in ECECs is currently lacking.

Metal-organic frameworks (MOFs) hold great potential in gas separation and storage. Graph neural networks (GNNs) have proven effective in exploring structure-property relationships and discovering new MOF structures. Unlike molecular graphs, crystal graphs must consider the periodicity and patterns.

This article shows the most recent data on the evolution of the number of resident physicians and vacancies from R1 to R5, as well as the number of programs and institutions accredited by the National Commission for Medical Residency (CNRM). It also discusses the types and modalities of evaluation of medical residency, with a focus on the assessment of competencies throughout in-service training, which were incorporated into the most recent CNRM resolution, at the end of 2023, which amended and updated the 2006 directives. Finally, it shows the experience of six Medical Societies that conduct periodic evaluation of resident physicians, presented at a Brazilian Medical Association event.
