Background: There are few studies comparing health status trends among middle-aged and older adults in countries currently experiencing a rapid demographic and economic transition in the Asia-Pacific, relative to their high-income regional counterparts. This study investigates trends in functional limitations among individuals aged 45 years and above in six major Asia-Pacific countries, ranging from middle- to high-income, from 2001 to 2019 and examines disparities across socioeconomic and demographic sub-groups.
Methods: Data on 778,507 individuals from seven surveys in three high-income countries (Australia, Japan, South Korea) and three middle-income countries (China, Indonesia, and India) were used. Activities of daily living (ADL), instrumental activities of daily living (IADL), and mobility measures served as indicators of functional limitations. Age-standardized prevalence was used to assess prevalence trends in functional limitations and their distribution across sex and age. Multivariate linear probability models were used to examine whether the patterns still hold when controlling for birth cohorts and socioeconomic and demographic factors.
Findings: People aged 45 years and above in Australia, Japan, and South Korea experienced declines in functional limitations, whereas increases were observed in India and Indonesia. The findings for China were unclear and varied depending on the indicator. Changes in prevalence of functional limitations over time were more pronounced among people aged over 60 years. Higher prevalence of functional limitations was observed for respondents with lower education and among those are not currently married across countries.
Interpretation: Study findings highlight the potential for cross-national learning to address functional limitations among older populations in low- and middle-income countries.
Funding: Not applicable.

Chronic pulmonary diseases pose a prominent health threat globally owing to their intricate pathogenesis and lack of effective reversal therapies. Nowadays, lung transplantation stands out as a feasible treatment option for patients with end-stage lung disease. Unfortunately, the use of this this option is limited by donor organ shortage and severe immunological rejection reactions.

Background: Oxygen therapy is critical and vital treatment for hypoxemia and respiratory distress, however, access to reliable oxygen systems remains limited in SSA. Despite WHO initiatives that distributed over 30,000 OC oxygen concentrators worldwide, SSA faces significant challenges related to their maintenance and use, due to harsh environmental conditions, technical skill shortages and inadequate infrastructure. This review aims to systematically identify and assess the literature on OC design adaptations, maintenance challenges, and knowledge gaps in SSA, providing actionable recommendations to inform innovative and context-sensitive solutions to improve healthcare delivery in the region.

Background: The retinal degenerative diseases retinitis pigmentosa (RP) and atrophic age- related macular degeneration (AMD) are characterized by vision loss from photoreceptor (PR) degeneration. Unfortunately, current treatments for these diseases are limited at best. Genetic and other preclinical evidence suggest a relationship between retinal degeneration and inflammation.

Background: The metabolic score for visceral fat (METS-VF) is a recently identified index for evaluating visceral fat, also referred to as abdominal obesity. The skeletal muscle mass index (SMI) serves as a critical measure for assessing muscle mass and sarcopenia. Both obesity and the reduction of muscle mass can significantly affect human health.
