Simulations can mimic the environment that refers to the surgery operation to improve the technical skills of the trainees. In this paper, we designed a new cardiac surgery simulative training system. The isolated pig heart was selected as the heart model. A mechanical device was designed to achieve the beating of heart model. At the same time, adjusting frequencies of mechanical movement could change the rating of heartbeat. In order to validate the rationality of the system, 12 non-medical specialty students and 12 medical specialty students were divided into two groups, which consecutively accepted seven-days of training for off-pump coronary artery bypass grafting using the cardiac surgery simulative training system. The time for completing bypass grafting before and after training were recorded. And the bridging outcomes of each trainee were assessed by 3 surgery cardiac surgeons using the object structured assessments of technical skill (OSATS) criteria. After training, each trainee could finish the bypass suturing in a shorter time than before training, and the scores of each trainee assessed by OSATS criteria were also improved. The results showed that the cardiac surgery simulative training system had better training effect in improving the surgical techniques, operation skills and proficiency of surgical instruments of trainees.

The effect of dynamic neuromuscular stabilization technique combined with Kinesio Taping on neuromuscular function and pain self-efficacy in individuals with chronic nonspecific low back pain: A randomized trial.
Medicine (Baltimore)
January 2025
Second Hospital of the Air Force Medical University, Xi 'an, China.
Background: This study investigates the therapeutic efficacy of dynamic neuromuscular stabilization (DNS) technology paired with Kinesio Taping in patients with persistent nonspecific low back pain, as well as the effect on neuromuscular function and pain self-efficacy.
Methods: A randomized controlled clinical study was conducted to collect clinical data on DNS combined with KT for the treatment of chronic nonspecific low back pain from November 2023 to April 2024. The inclusion criteria were patients with chronic nonspecific lower back pain, aged between 18 and 30 years old, and without serious underlying medical conditions, such as cardiac disease, hypertension, and diabetes.
Digital Mindfulness Training for Burnout Reduction in Physicians: Clinician-Driven Approach.
JMIR Form Res
January 2025
Brown University, Department of Behavioral and Social Sciences, Providence, RI, United States.
Background: Physician burnout is widespread in health care systems, with harmful consequences on physicians, patients, and health care organizations. Mindfulness training (MT) has proven effective in reducing burnout; however, its time-consuming requirements often pose challenges for physicians who are already struggling with their busy schedules.
Objective: This study aimed to design a short and pragmatic digital MT program with input from clinicians specifically to address burnout and to test its efficacy in physicians.
AI-Driven Innovations for Early Sepsis Detection by Combining Predictive Accuracy With Blood Count Analysis in an Emergency Setting: Retrospective Study.
J Med Internet Res
January 2025
Division of Clinical Pathology, Department of Pathology, Tri-Service General Hospital, National Defense Medical Center, Taipei, Taiwan.
Background: Sepsis, a critical global health challenge, accounted for approximately 20% of worldwide deaths in 2017. Although the Sequential Organ Failure Assessment (SOFA) score standardizes the diagnosis of organ dysfunction, early sepsis detection remains challenging due to its insidious symptoms. Current diagnostic methods, including clinical assessments and laboratory tests, frequently lack the speed and specificity needed for timely intervention, particularly in vulnerable populations such as older adults, intensive care unit (ICU) patients, and those with compromised immune systems.

Purpose: Older adults with cancer have unique needs, which likely influence surgical outcomes in the geriatric oncology population. We conducted a systematic review to describe the literature focused on perioperative supportive care interventions for older adults with cancer undergoing surgery.
Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we performed a comprehensive search using the Ovid MEDLINE, CINAHL, and Embase databases for literature published from January 2010 to October 2023.
Intra- and interobserver agreement of proposed objective transvaginal ultrasound image-quality scoring system for use in artificial intelligence algorithm development.

Robinson Research Institute, University of Adelaide, Adelaide, Australia.
Objectives: The development of valuable artificial intelligence (AI) tools to assist with ultrasound diagnosis depends on algorithms developed using high-quality data. This study aimed to test the intra- and interobserver agreement of a proposed image-quality scoring system to quantify the quality of gynecological transvaginal ultrasound (TVS) images, which could be used in clinical practice and AI tool development.
Methods: A proposed scoring system to quantify TVS image quality was created following a review of the literature.
