Analysis of influencing factors and structural changes in hospitalization expenses for heart failure patients under the DRG payment system reform
Objective This study aimed to explore the influencing factors and structural changes in hospitalization expenses for heart failure (HF) patients under the Diagnosis-Related Group (DRG) payment system reform, providing a scientific basis for hospitals to control the hospitalization costs of HF patients. Methods A total of 4,791 hospitalized HF patients from a secondary Grade-A hospital in Liuzhou City between January 1, 2015, and July 31, 2025, we…
Association of past 12-month sports injury history with hop limb symmetry index in physically active university students
Background Physically active university students are exposed to relatively high levels of sport and training, and unrecognized functional asymmetry may persist after sports injury. The hop limb symmetry index (hop LSI) is a feasible field-based assessment measure in university physical education and training settings and may help describe residual functional asymmetry at the group level and inform decisions about further functional monitoring. Ob…
Early mortality risk prediction in severe fever with thrombocytopenia syndrome using an interpretable machine learning model based on routine clinical parameters
Background: Severe Fever with Thrombocytopenia Syndrome (SFTS) is characterized by high mortality and rapid progression, necessitating accurate early prognosis to optimize supportive care. However, current predictive tools often lack interpretability, require sophisticated tests unavailable in resource-limited areas, or suffer from poor generalizability. This study aimed to develop an interpretable, parsimonious, and deployable machine learning m…
Progressive Reinforcement Learning for Point-Feature Label Placement in Map Annotation
In the era of information explosion, the effective configuration of labels on maps is crucial for the rapid comprehension of information. The point-feature label placement problem, particularly in large-scale and high-density scenarios with spatial mutual-exclusion constraints, is a classic NP-hard discrete optimization challenge. Existing metaheuristic algorithms (e.g., Simulated Annealing and Genetic Algorithm) often struggle to achieve high-qu…
Depression and biological aging
BACKGROUND: Depression has significantly associated with biological aging. Although lower social status is generally linked to increased vulnerability to aging, the biological impact of depression may differ according to social status, possibly due to variations in stress perception and structural position. However, it remains unclear how depression is related to biological age acceleration across different social risk profile (SRP). METHODS: We …
Association between blood heavy metal levels and COPD risk
Objective: Heavy metals such as cadmium (Cd), lead (Pb), mercury (Hg), selenium (Se), and manganese (Mn) are commonly found in the environment and could increase the risk of COPD, potentially through key biological mechanisms such as oxidative stress and inflammation. Nonetheless, evidence on the association between exposure to these metals and COPD remains limited and inconclusive. This study aims to evaluate the potential association between bl…
Factors Influencing Hospitalization Expenses Among Patients with Lung Cancer in China
Lung cancer poses a serious threat to human health. The direct medical expense and indirect social economic burden caused by high morbidity and poor prognosis rate of malignant tumor are higher than other diseases around the world, especially in some developing countries such as China. Guangxi is one of the less developed provinces in China and it is more essential to control the pressure on medical costs. We intend to explore influential factors…
Clinical characteristics and prognosis of pneumonia-related bloodstream infections in the intensive care unit
Background Bloodstream infections (BSI) are one of the most severe healthcare-associated infections in intensive care units (ICU). However, there are few studies on pneumonia-related BSI (PRBSI) in the ICU. This study aimed to investigate the clinical and prognostic characteristics of patients with PRBSI in the ICU and to provide a clinical basis for early clinical identification. Methods We retrospectively collected data from patients with bacte…
Fragile promise
People who consider themselves moral sometimes use self‐serving justifications to rationalize their selfish behaviours. Previous studies have tested the role of ambiguity in justifying wrongdoings, but it remains unclear whether ambiguity also plays a role in justifying promise‐breaking behaviour and whether heterogeneity exists. To investigate justification in promise‐breaking, we introduced a new experimental paradigm called the card‐guessing t…
Irrigation water pricing based on the Eles-WPTI model in the Yinda-Jihuang project of China
Water pricing is the key to maximizing the economic and social benefits of the water transfer project. In this study, we propose the extended linear expenditure system-water price tolerance index (ELES-WPTI) model that combines the ELES model and the WPTI method for water pricing. Firstly, the ELES model is used to estimate the price elasticity of water demand and the basic demand for farmers of different income levels. Secondly, the WPTI method …
Distribution of the compression and expansion of morbidity in 194 countries and territories, 1990-2016
Studies on detailed types of health changes and the associations between the types and income inequality are inadequate. This study analyses the global distribution of the compression and expansion of morbidity in 194 countries and territories between 1990 and 2016, and investigates the role of income inequality in the distribution. This study shows that all seven types of health changes coexist, despite being distributed unevenly. The relative e…
The path to healthy ageing in China
The impacts of long-term care insurance on health care utilization and expenditure
Long-term care insurance (LTCI) is one of the important institutional responses to the growing care needs of the ageing population. Although previous studies have evaluated the impacts of LTCI on health care utilization and expenditure in developed countries, whether such impacts exist in developing countries is unknown. The Chinese government has initiated policy experimentation on LTCI to cope with the growing and unmet need for aged care. Empl…
Public long‐term care insurance scheme and informal care use among community‐dwelling older adults in China
The public long-term care insurance (LTCI) scheme has been implemented in a few countries. Although the hypotheses of crowding-out, crowding-in and specialisation can facilitate our understanding of the relationship between LTCI and informal care use, existing studies may suffer from reverse causality. Employing a quasi-experimental design, this study examined the policy effect of LTCI on informal care use among community-dwelling older adults in…
Analysis on Influencing Factors of Hospitalization Cost for Patients With Kidney Stone Disease in Western China
To explore the influencing factors causing the change of hospitalization cost (HC) in patients with kidney stone disease (KSD), control the increase of HC and reduce the economic burden of patients. Data were derived from one provincial general public hospital in Guangxi, China. Model of Artificial Neural Networks and Multiple Linear Regression were used in analyze the external factors from 2012 to 2016. From 2012 to 2016, the total cost increase…
Service Delivery Reforms for Asian Ageing Societies
Doctor and hospital-based healthcare delivery system requires more drastic reform for an aged society. This fact implies that strengthening primary health care is not only useful for current health issues but also an investment for the aged society near future in low- and middle-income countries
Adapting global shared socio-economic pathways for national scenarios in Japan
Shared socio-economic pathways (SSPs) are alternative global development scenarios focused on the mitigation of and adaptation to climate change. However, global SSPs would need revised versions for regional or local assessment, which is the so-called extended version, because global narratives may lack region-specific important drivers, national policy perspectives, and unification of data for each nation. Thus, it is necessary to construct scen…
A multilevel analysis of social capital and self-rated health
The Contributions of Diseases to Disability Burden Among the Elderly Population in China
Along with the epidemiologic transition, chronic conditions have become the predominant contributor to disability burden among elderly persons in China. And, presbycusis, cataracts, cerebrovascular disease, osteoarthritis, and unclassified injuries should be the priorities in ameliorating disability
HIV/Aids knowledge, contraceptive knowledge, and condom use among unmarried youth in China
This study aims to describe HIV/AIDS knowledge, contraceptive knowledge, and their relationships to condom use among unmarried youth in China, especially the mediating effect of consciousness. The first nationally representative survey data on sexual and reproductive health of unmarried Chinese youth was used and analysis was carried out according to the AIDS Risk Reduction Model. Among the sexually active respondents, about 30% had not used a co…
The Canadian National Retirement Risk Index
This article measures a Canadian National Retirement Risk Index (NRRI). Originally developed by the Center for Retirement Research at Boston College, the NRRI is a forward-looking measure that evaluates the proportion of working-aged individuals who are at risk of not maintaining their standard of living in retirement. The Canadian retirement income system has been very effective in reducing elderly poverty, but our results suggest that it has be…
