Purpose: White matter hyperintensity (WMH) is suggested to cause stroke and dementia in older adults. Retinal structural thicknesses revealed by optical coherence tomography (OCT) are associated with structural changes in the brain. We aimed to explore the association between the peripapillary retinal nerve fiber layer (RNFL) and cerebral microstructural changes in participants with white matter hyperintensities (WMH).
Methods: Seventy-four participants (37 controls, healthy control (HC), and 37 older adults with WMH) underwent retinal and brain imaging using OCT and magnetic resonance imaging (MRI) respectively. Peripapillary RNFL thickness was assessed by the OCT. Gray matter volume (GMV) was assessed from a T1-weighted MRI. White matter integrity was assessed with diffusion tensor imaging (DTI) while WMH severity was assessed with the Fazekas scale. All participants underwent a neuropsychological examination (Mini-Mental State Examination, MMSE).
Results: Older adults with WMH showed thinner peripapillary RNFL ( = 0.004) thickness when compared with the control group after adjusting for age, hypertension and gender. In our older adults with WMH, RNFL thickness correlated with fractional anisotropy (FA) in the superior longitudinal fasciculus (SLF) (Rho = -0.331, < 0.001). In older adults with WMH, RNFL was significantly associated with MMSE scores (Rho = 0.422, < 0.001) and Fazekas scores (Rho = -0.381, = 0.022) respectively.
Conclusions: We suggest neurodegeneration of peripapillary RNFL in older adults with WMH was associated with cerebral microstructural volume, impaired cerebral axonal damage, and cognitive performances. OCT metrics may provide evidence of neurodegeneration that may underpin WMH and cerebral microstructural changes in the brain.

Aging is accompanied by a decline in neovascularization potential and increased susceptibility to ischemic injury. Here, we confirm the age-related impaired neovascularization following ischemic leg injury and impaired angiogenesis. The age-related deficits in angiogenesis arose primarily from diminished EC proliferation capacity, but not migration or VEGF sensitivity.

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) with onset in youth may be more consequential for adverse outcomes than that detected later in adulthood. Transaminitis in the general population is a marker of the prevalence of MASLD. There are no previous community-based studies in Indian youth assessing the prevalence of transaminitis.

Background: Little is known about the practices and resources employed by general practitioners (GPs) in Singapore to manage late-life depression. As the country is stepping up its efforts to promote collaborative care across community mental health and geriatric care, understanding GPs' current practices when managing late-life depression appears timely.
Methods: This qualitative descriptive study explored the perspectives on late-life depression of 28 private GPs practicing in Singapore through online semi-structured group and individual interviews.

Purpose: Oral corticosteroids (OCS) are recommended for the treatment of exacerbations in people with COPD; however, high cumulative lifetime doses (≥1000mg prednisolone-equivalent) are associated with adverse health effects. This issue is well defined in asthma but is less well understood in COPD. The aim of this study was to examine cumulative OCS dispensed to people with COPD over 12 months.

Purpose: The effect of the diurnal temperature range (DTR) on human health in diverse geographic areas and the potential confounding factors are not fully understood. Additionally, while a robust association has been reported between temperature and cardiomyopathy (CM), evidence of the impact of DTR is relatively limited. Here, we determined whether an association exists between DTR and CM hospitalisations in vulnerable populations.
