The global aging population raises concerns about heart failure (HF), yet its association with accelerated biological age (BA) remains inadequately understood. We aimed to examine the longitudinal association between BA acceleration and incident HF risk, assess its modifying effect on genetic susceptibility, and how much BA acceleration mediates the impact of modifiable health behaviors on incident HF. We analyzed 274,608 UK Biobank participants without HF at baseline.

Article Synopsis
  • Mental stress-induced myocardial ischemia (MSIMI) significantly increases cardiovascular events, yet its precise mechanisms related to myocardial blood flow (MBF) are not fully understood.
  • A study using cardiac positron emission tomography (PET-CT) revealed that women with angina but no obstructive coronary artery disease (ANOCA) had a much higher prevalence of MSIMI compared to healthy controls.
  • Results showed that these participants had lower MBF and coronary flow reserves, indicating that impaired coronary microvascular function plays a crucial role in the development of MSIMI in individuals with ANOCA.

Background: While the association between screen time (ST) and psychosocial well-being has been extensively examined, limited studies have investigated the dynamic patterns of ST, and their impact on subsequent psychosocial well-being among adolescents. Therefore, this longitudinal study aimed to examine the association between ST trajectories and the subsequent psychosocial well-being among Chinese adolescents.

Methods: Data were drawn from the Longitudinal Study of Adolescents' Mental and Behavioral Well-being Research (Registration No.

Background: Few studies have integrated the impact of individual and cumulative childhood maltreatment on multiple psychiatric symptoms, with the mechanisms underlying these associations largely unknown. This study aims to comprehensively assess the associations between childhood maltreatment, multiple peripheral immune biomarkers, and various psychiatric symptoms in adulthood and to explore whether peripheral immune inflammation plays a mediator role in the associations between childhood maltreatment and psychiatric symptoms in adulthood.

Methods: Using data from the UK Biobank, we constructed a retrospective cohort study of 138,915 participants who provided self-reported childhood maltreatment and had peripheral immune biomarkers assessed.

Cystatin C (Cys C), a crucial renal disease marker for chronic kidney disease (CKD), plays a vital role in early diagnosis and treatment guidance. However, most current methods for detecting Cys C rely on a single signal and find it difficult to perform noninvasive and portable diagnosis. Here, we developed a ratiometric fluorescent carbon dot (CD) detection system for point-of-care testing (POCT) of Cys C through fluorescence resonance energy transfer (FRET).

Article Synopsis
  • Depression and high-sensitivity C-reactive protein (hs-CRP) are linked to worse outcomes in coronary heart disease (CHD) patients, but their combined effects had not been well-studied before this research.
  • The study assessed 414 CHD patients over two years using tools to measure depression and anxiety, finding that those with both elevated depression and high hs-CRP faced significantly higher risks of noncardiac readmissions and other adverse events.
  • While high hs-CRP alone was associated with increased risks, elevated anxiety did not significantly impact patient outcomes, and no interactions between depression or anxiety and hs-CRP were found.

Background: Previous research revealed an association between coffee consumption and depressive symptoms. However, the results differed between studies in adults and adolescents. Additionally, limited research on coffee and depressive symptoms has distinguished between black and sugar-sweetened coffee.

Benzophenone-3 (BP-3), commonly used in personal care products, is routinely detected in environmental and human matrices. Evidence delineates a correlation between gestational BP-3 exposure and emotional and social disorders in children and adolescents. However, sensitive target cells and the mode of action underlying the early responses to environmentally relevant level of BP-3 exposure remain unclear.

Objective: Limited understanding exists regarding the cumulative impact of childhood household dysfunction (CHD) on adolescent depressive symptoms in developing countries, as well as the role of lifestyles in this association. This study aims to explore the associations of individual and cumulative CHD indicators with depressive symptoms among Chinese adolescents. Additionally, we investigate potential interactions and joint associations of CHD and lifestyles on depressive symptoms.

Purpose: Traditional fasting causes considerable discomfort without added assurance of security, whereas oral carbohydrate beverage offers an alternative to improve medical experience. This study aims to explore the impact of different types and dosages of oral fluids loading before painless bidirectional endoscopy on the gastric emptying and wellbeing.

Methods: 180 patients arranged for bidirectional endoscopy with intravenous anesthesia were randomized: patients in the control group (Group C) obeyed standard fasting; the 200 mL carbohydrate group (Group P1), 400 mL carbohydrate group (Group P2), 200 mL water group (Group W1) and 400 mL water group (Group W2) respectively consumed 200 mL or 400 mL corresponding clear liquids 2 h before the procedure.

Article Synopsis
  • - This study examined how following the 24-hour movement behavior guidelines (which include physical activity, reduced screen time, and sufficient sleep) affects the quality of life (QOL) for adolescents with idiopathic scoliosis.
  • - Out of 1073 participants, only a small percentage adhered to all movement behavior guidelines, and those who did reported significantly higher QOL scores compared to those who did not follow any guidelines.
  • - The research found that the benefits of meeting these guidelines were most notable in adolescents who didn't experience back pain and who had a positive self-image, emphasizing the need for healthy lifestyle habits.

  • The study examined the link between how quickly smokers light their first cigarette after waking (TWFC) and various health outcomes, including all-cause mortality and cardiovascular disease (CVD) mortality.
  • Data from 32,519 smokers aged 40-70 from the UK Biobank was used, with TWFC assessed through a questionnaire.
  • Findings showed that shorter TWFC (especially less than 5 minutes) is associated with increased risks of overall mortality and CVD-related deaths, while no significant link was found with stroke mortality.

Background And Objectives: Accumulating evidence suggests that low grip strength (GS) is associated with a faster cognitive decline, but most previous studies have measured GS at a single time point, ignoring changes in GS. We aimed to explore the association of the GS loss rate with the sequent cognitive decline, as well as the moderating role of social isolation in older adults.

Research Design And Methods: Data were from the English Longitudinal Study of Ageing.

Non-small cell lung cancer (NSCLC) is a major disease with high incidence, low survival rate and prone to develop drug resistance to chemotherapy. The mechanism of secondary drug resistance in NSCLC chemotherapy is very complex, and studies have shown that the abnormal activation of STAT3 (Signal Transducer and Activator of Transcription 3) plays an important role in it. In this study, the pGPU6/GFP/Neo STAT3-shRNA recombinant plasmid was constructed with STAT3 as the precise target.

Background: Angina with no obstructive coronary disease (ANOCA) and ischemia with no obstructive coronary disease, prevalent yet underrecognized conditions, mostly affect women. Previous studies rarely distinguished between them. We aimed to compare the prevalence of objective ischemia through various examinations in women with ANOCA and assess the impact of objective and subjective ischemia on their mental health.

Background: Exercise capacity serves as a direct representation of cardiac function. The Duke Activity Status Index (DASI), a self-administered 12-item questionnaire, covers aspects of daily living, household tasks, sexual function, and physical activity. Although widely used to evaluate exercise capacity, its validation in Chinese cardiovascular disease (CVD) patients has not been thoroughly explored.
