Facilitators and barriers of life-space mobility in older adults with ischemic stroke
Introduction Older adults with ischemic stroke are particularly vulnerable to restricted life-space mobility, which is linked to adverse health outcomes. This study aimed to explore facilitators and barriers of life-space mobility among older adults with ischemic stroke using the COM-B model and to inform the development of targeted interventions. Methods A descriptive qualitative design was adopted. Semi-structured, face-to-face interviews were …
From symptom onset to care-seeking
Background Cerebral infarction (ischemic stroke) is a highly time-sensitive acute cerebrovascular event, yet prehospital delays in patients’ accessing medical care remain prevalent across various countries and healthcare systems. Previous studies have primarily attributed delays to inadequate symptom recognition or barriers in healthcare accessibility, with limited systematic exploration of their formation mechanisms from a decision-making proces…
Deployment, dispatch, and delivery
Objective: Out-of-hospital cardiac arrest (OHCA) constitutes a significant global public health burden, and early defibrillation is essential for patient survival. However, traditional emergency medical services frequently struggle to achieve the requisite response times. Drone-delivered automated external defibrillators (AEDs) have emerged as an innovative intervention strategy to address this challenge. This scoping review aimed to systematical…

Trends and lifestyle contributions to frailty in US adults aged 50 and older
Frailty is a critical geriatric syndrome associated with modifiable lifestyle factors, yet their population-level contributions remain unclear. This study aimed to quantify the proportion of frailty incidence attributable to modifiable lifestyle factors and assess temporal trends in the US. We analyzed data from 26,247 participants in the Health and Retirement Study (2004–2020) involving adults aged ≥ 50 years. Frailty was assessed using the Paul…
Comparative evaluation of the accuracy and reliability of ChatGPT versions in providing information on Helicobacter pylori infection
Objective: (Hp) infection, as well as to explore their potential applications within the healthcare domain. Methods: A panel of experts compiled and refined a set of 27 clinical questions related to Hp. These questions were presented to each ChatGPT version, generating three distinct sets of responses. The responses were evaluated and scored by three gastroenterology specialists utilizing a 5-point Likert scale, with an emphasis on accuracy and c…

Trends in the prevalence of vision impairment among the oldest-old Chinese population from 1998 to 2018
Background: Vision impairment has become a prominent public health issue worldwide. However, little is known about vision impairment prevalence trends among the oldest-old adults in China. This study aimed to examine 20-year trends in the prevalence of vision impairment among the oldest-old Chinese adults and explore the contributions of sociodemographic variables, health behaviours, and chronic conditions to the trends. Methods: This retrospecti…
Anthropometric characteristics of children living in food-insecure households in the USA
Objective: This study provides information on food insecurity and child malnutrition in a technologically advanced nation. Design: Population-based study using multistage probability cluster sampling design to collect survey data. Multivariable regression models were used to determine associations between food security status and various malnutrition indices. Setting: We used a national sample from the US National Health and Nutrition Examination…
Associations between Multimorbidity and Physical Performance in Older Chinese Adults
Background : Evidence on the association between physical performance and multimorbidity is scarce in Asia. This study aimed to identify multimorbidity patterns and their association with physical performance among older Chinese adults. Methods : Individuals aged ≥60 years from the China Health and Retirement Longitudinal Study 2011-2015 ( N = 10,112) were included. Physical performance was measured by maximum grip strength (kg) and average gait …
Multimorbidity among Two Million Adults in China
To explore the multimorbidity prevalence and patterns among middle-aged and older adults from China. Data on thirteen chronic diseases were collected from 2,097,150 participants aged over 45 years between January 1st 2011 and December 31st 2015 from Beijing Medical Claim Data for Employees. Association rule mining and hierarchical cluster analysis were applied to assess multimorbidity patterns. Multimorbidity prevalence was 51.6% and 81.3% in the…
Food insecurity is associated with higher-than-normal blood serum copper level
Objective: To determine associations between household food security status and risk of Cu toxicity. Design: A population-level cross-sectional study to determine adult household food security status and its relationship with serum total Cu concentration (serum Cu) using multivariable regression models. Setting: Adult participants in the US National Health and Nutrition Examination Survey (NHANES) 2011–2014. Participants: The NHANES phlebotomy da…
