Background: The impact of depression and anxiety on heart rate variability (HRV) is not clear in adolescents. We hypothesised that HRV investigation in adolescents may early prevent the mental diseases occurrence.
Methods: Three hundred and thirty-three seventh grade students participated in this study programme. HRV instrumental analysis and spectral with scale of depression were measured respectively.
Results: It showed that among the participants, the depression score of female was higher than male. The population with lower depression score present with lower high frequency and higher low frequency/high frequency ratio but not statistically significant. Oppositely, participants with higher depression score were increased with heart rate and present with lower standard deviation of heart rate. However, it is also not statistically significant.
Conclusion: This study supported the positive relation between HRV and depression, especially in the female gender. Therefore, HRV in depression may be beneficial in the detection and prevention of mental disorder development, even suicide behaviour in teenagers.

Background: Intermediate-high risk pulmonary embolism (PE) carries a significant risk of hemodynamic deterioration or death. Treatment should balance efficacy in reducing clot burden with the risk of complications, particularly bleeding. Previous studies on high-dose, short-term thrombolysis with alteplase (rtPA) showed a reduced risk of hemodynamic deterioration but no change in mortality and increased bleeding complications.

Background/purpose: Transcatheter aortic valve replacement (TAVR) with ACURATE neo2 showed better hemodynamic outcomes by mitigating paravalvular leakage (PVL) compared with ACURATE neo, and revealed promising one-year outcomes in single-arm studies. However, studies comparing the hemodynamic and clinical outcomes of the two valves are still scarce. Therefore, this study aimed to compare the one-year hemodynamic and clinical outcomes between the neo2 and neo.

Background: Sedentary behaviour (SB) is detrimental to cardiometabolic disease (CMD) risk, which can begin in young adulthood. To devise effective SB-CMD interventions in young adults, it is important to understand which context-specific SB (CS-SB) are most detrimental for CMD risk, the lifestyle behaviours that cluster with CS-SBs and the socioecological predictors of CS-SB.
Methods And Analysis: This longitudinal observational study will recruit 500 college-aged (18-24 years) individuals.

Background: Cardiac troponin T (cTnT) and N-terminal B-type natriuretic propeptide (proBNP) are mainly used as biomarkers to diagnose specific conditions of the heart, but they also have predictive ability. Our aim was to study their associations with cardiovascular and all-cause mortality in an older population in non-acute conditions.
Methods: A population-based study with a ten-year follow-up.

Although angiotensin 1-7 (Ang 1-7) and its role as a part of the "protective" axis of the renin-angiotensin system are well described in the literature, the mechanisms of its angiotensin II-like pressor and tachycardic effects following its acute central administration are not fully understood. It was the aim of the present study to examine which receptors contribute to the aforementioned cardiovascular effects. Ang 1-7 and antagonists for glutamate, GABA, vasopressin, thromboxane A (TP), α-adrenergic, and P2X purinoceptors or modulators of oxidative stress were injected into the paraventricular nucleus of the hypothalamus (PVN) of urethane-anesthetized male Wistar rats.
