Introduction: Educational interventions can raise awareness and understanding in population groups and may help to achieve changes in behavior.
Objective: To determine if the educational handwashing program applied to high-school students reduces the colonization of infectious bacteria on the hands.
Methods: A non-randomized quasi-experimental study was carried out using consecutive sampling of the students of the last year of high-school who were divided into an intervention group and a control group. Data were obtained before and after the implementation of the educational program. Samples were taken from the dominant hand for bacterial culture, and a questionnaire was applied that assessed knowledge of hand hygiene before and after the program. The program was aimed at improving the level of understanding and attitudes of students regarding hand hygiene.
Results: Of 208 samples obtained, the most frequent agents before and after the educational program were Staphylococcus epidermidis (39% versus 23%) and Staphylococcus aureus (21% versus 15%). The average number of colonies was 236 and 183 respectively (p = 0.35).
Conclusion: The educational program managed to improve the level of understanding about hand hygiene; however, it was not enough to reduce bacterial colonization, so other behaviors such as direct supervision should be considered.

Effects of population aging on quality of life and disease burden: a population-based study.

Background: As population aging intensifies, it becomes increasingly important to elucidate the casual relationship between aging and changes in population health. Therefore, our study proposed to develop a systematic attribution framework to comprehensively evaluate the health impacts of population aging.
Methods: We used health-adjusted life expectancy (HALE) to measure quality of life and disability-adjusted life years (DALY) to quantify the burden of disease for the population of Guangzhou.
Effects on impulsivity and delay discounting of intermittent theta burst stimulation add-on to dialectical behavioral therapy in borderline personality disorder: a randomized, sham-controlled pilot trial.

Background: Dialectical behavioral therapy (DBT) and repetitive transcranial magnetic stimulation (rTMS) are both effective in treating borderline personality disorder (BPD). Impulsivity and impaired decision-making are prominent features of BPD, and therapeutic interventions targeting these symptoms could lead to significant improvements.
Objective/hypothesis: We hypothesized that intermittent theta burst stimulation (iTBS), a modified rTMS protocol that targets the left dorsolateral prefrontal cortex, would enhance the therapeutic effects of DBT, leading to greater improvements in impulsivity and decision-making compared with sham stimulation.

Simulation-based education (SBE) has become an integral part of training in health professions education, offering a safe environment for learners to acquire and refine clinical skills. As a non-ionising imaging modality, ultrasound is a domain of health professions education that is particularly supported by SBE. Central to many simulation programs is the use of animal models, tissues, or body parts to replicate human anatomy and physiology.

Background: The one health (OH) approach, linking human, animal, and environmental health, relies on effective community engagement (CE), education, stewardship, and effective regional and global partnerships. For real impact, communities should be at the centre of research agenda setting and program implementation. This review aimed at synthesizing empirical evidence on how communities are involved in one health research.

Recent research has highlighted widespread dysregulation of alternative polyadenylation in amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration with TDP-43 pathology (FTLD-TDP). Here, we identify significant disruptions to 3` UTR polyadenylation in the ALS/FTLD-TDP mouse model rNLS8 that correlate with changes in gene expression and protein levels through the re-analysis of published RNA sequencing and proteomic data. A subset of these changes are shared with TDP-43 knock-down mice suggesting depletion of endogenous mouse TDP-43 is a contributor to polyadenylation dysfunction in rNLS8 mice.
