RESUMEN
BACKGROUND: In the present study, we aimed to investigate whether early cardiac biomarker alterations and echocardiographic parameters, including left atrial (LA) strain, can predict anthracycline-induced cardiotoxicity (AIC) and thus develop a predictive risk score. METHODSâANDâRESULTS: The AIC registry is a prospective, observational cohort study designed to gather serial echocardiographic and biomarker data before and after anthracycline chemotherapy. Cardiotoxicity was defined as a reduction in left ventricular ejection fraction (LVEF) ≥10 percentage points from baseline and <55%. In total, 383 patients (93% women; median age, 57 [46-66] years) completed the 2-year follow-up; 42 (11.0%) patients developed cardiotoxicity (median time to onset, 292 [175-440] days). Increases in cardiac troponin T (TnT) and B-type natriuretic peptide (BNP) and relative reductions in the left ventricular global longitudinal strain (LV GLS) and LA reservoir strain [LASr] at 3 months after anthracycline administration were independently associated with subsequent cardiotoxicity. A risk score containing 2 clinical variables (smoking and prior cardiovascular disease), 2 cardiac biomarkers at 3 months (TnT ≥0.019 ng/mL and BNP ≥31.1 pg/mL), 2 echocardiographic variables at 3 months (relative declines in LV GLS [≥6.5%], and LASr [≥7.5%]) was generated. CONCLUSIONS: Early decline in LASr was independently associated with subsequent cardiotoxicity. The AIC risk score may provide useful prognostication in patients receiving anthracyclines.

Associations of exertional heat exhaustion (EHE)-related symptoms with lifestyle habits and health factors specific to female athletes, ranked by relative risks from high to low, remain elusive. Addressing this issue would benefit athletes and coaches, ensuring safer practices during summer sports activities. To address this issue, we distributed paper-based questionnaires to seven universities in Japan, and 983 respondents completed our survey. The questionnaires covered various personal characteristics, lifestyle habits, perceived health factors, perceived athletic activity, and EHE-related symptoms. In this retrospective case-control study, we analyzed the relationships of EHE-related symptoms (objective variables) with lifestyle habits, health factors, and athletic activity conditions (explanatory variables) using the partial proportional odds model. The questionnaire responses revealed that perceived dehydration, sickness, loss of appetite, perceived accumulated fatigue, perceived mental stress, lack of ambient wind, and insufficient rest breaks were positively associated with EHE-related symptoms, with relative risks ranging from high to low. Using an air conditioner during sleep and having a sleep duration of ≥ 6 h were associated with a reduced risk of EHE-related symptoms. The study results suggest that female athletes should be allowed to postpone exercise or reduce its intensity and volume based on their perceptions of dehydration, sickness, loss of appetite, accumulated fatigue, and mental stress in summer to prevent heat-related illnesses.

Introduction: This study examined the effects on upper limb function, activities of daily living, and stress responses when wearing a wrist orthosis made of padded fiberglass or thermoplastic and provided essential information for selecting an orthosis. Methods: Thirty-one healthy adults performed two tests while not wearing a wrist orthosis, wearing a padded fiberglass wrist orthosis, and wearing a thermoplastic wrist orthosis. The Purdue Pegboard Test examined upper limb control. In the second test, the actions indicated by the Hand20 questionnaire were performed while wearing a wrist orthosis. An electrocardiogram was obtained before and after each test to identify any changes in sympathetic nervous system activity. Results: The Purdue Pegboard Test scores were significantly higher when not wearing a wrist orthosis than when wearing wrist orthosis, and the Hand20 scores for all question were significantly lower. Thermoplastic wrist orthoses had fewer restrictions for upper limb function compared to padded fiberglass wrist orthoses, however activities of daily living were more limited. The low frequency/high frequency ratio and high frequency measures showed no significant differences. Conclusions: Pegboard test scores and the Hand 20 scores suggest that a wrist orthosis causes restriction of upper limb function.
RESUMEN
Patient engagement for patient safety is emphasized in recent years. Therefore, the Committee on Quality and Patient Safety of the Japan Primary Care Association developed a Japanese Patient Engagement Promotion Training (J-PEPT) course. J-PEPT promotes to facilitate the implementation of PE strategies and contributes to nationwide dissemination for patient safety.
