Article Synopsis
  • Muscular strength, particularly measured by handgrip strength (HGS), is an important indicator of health and a predictor of age-related diseases, but no international benchmarks exist for HGS across different ages and sexes.
  • The study systematically analyzed data from over 2.4 million adults across 69 countries to establish sex- and age-specific norms for HGS, identifying a peak in strength between ages 30 and 39 before a gradual decline.
  • Findings revealed that while absolute and body size-normalized HGS improves slightly in early adulthood, a more significant drop occurs from middle to late adulthood, with males generally experiencing a faster decline than females.

Background: Patient-reported experience measures (PREMs) are valuable tools to evaluate patient-centredness (PC) from the patients' perspective. Despite their utility, a comprehensive PREM addressing PC has been lacking. To bridge this gap, we developed the preliminary version of the Experienced Patient-Centeredness Questionnaire (EPAT), a disease-generic tool based on the integrative model of PC comprising 16 dimensions.

Article Synopsis
  • The study investigates how body mass index (BMI) during different life stages (childhood, adolescence, and young adulthood) affects the thickness of carotid arteries (cIMT) in adulthood.
  • Using data from two large studies, researchers found that higher BMI levels over a lifetime are linked to increased cIMT in adults.
  • The most significant impact on cIMT came from BMI during young adulthood for most participants, while for a specific group, childhood BMI was more influential, highlighting the importance of managing BMI at various life stages for cardiovascular health.

Article Synopsis
  • Congestion significantly impacts outcomes in acute heart failure, and assessing it can be complicated, making effective treatment difficult; residual congestion at discharge increases risks of re-hospitalization and mortality.
  • A study involving 233 patients with acute heart failure assessed the link between pro-adrenomedullin levels and congestion as well as clinical outcomes like in-hospital death and post-discharge mortality, revealing that higher pro-adrenomedullin levels are tied to worse outcomes.
  • Findings suggest that monitoring pro-adrenomedullin can serve as a useful marker for evaluating congestion and guiding therapies in acute heart failure patients, with elevated levels correlating with heightened risk of worsening heart failure and death post-discharge.

Background: Both adverse childhood experiences (ACEs) and lifestyle factors have been associated with risk of cardiovascular diseases (CVDs) in later life, but whether and to what extent adherence to a healthy lifestyle in adulthood can offset the increased cardiovascular risk associated with ACEs is unclear. We aimed to determine whether and to what extent adopting to a healthy lifestyle in adulthood can offset the risk of CVDs in individuals according to their ACEs.

Methods: A prospective cohort study included 143,869 participants aged 38-72 years, free of CVDs at baseline from the UK Biobank.

Importance: Recent evidence suggests that childhood levels of serum lipids, blood pressure, body mass index (BMI), and smoking contribute to adult risk of cardiovascular disease (CVD). Evidence is lacking on whether this is independent of adult risk levels.

Objective: To quantify direct and indirect effects of childhood risk factors on adult CVD via adulthood risk factors using mediation analysis, and to quantify their relative importance during different life-course stages using a life-course approach.

Background: Non-communicable diseases (NCDs) are responsible for many deaths. They are associated with several modifiable and metabolic risk factors and are therefore prone to significant regional variations on different scales. However, only few intra-urban studies examined spatial variation in NCDs and its association with social circumstances, especially in Germany.
