OPHTHALMOLOGY

Researchers delve into the impact of ageing on the central nervous system, focusing on the retina, a key area affected by age-related changes. Neurons and synapses, crucial for circuit function, require maintenance throughout an individual's lifetime. Ageing is a significant risk factor for neural diseases, even without illness, causing declines in nervous system function. This article reviews the structural and molecular effects of ageing on inner and outer retina circuits while also exploring the role of non-neuronal cell types. Understanding retinal ageing is vital for preventing age-related neural decline and restoring neural function.

Reduced sleep spindle oscillations may provide a new marker linking sleep dysfunction with Alzheimer’s disease pathology.

Sleep Oscillations May Link Sleep Dysfunction to Alzheimer’s Disease

A study found that the peak amplitude of infraslow oscillations in sleep spindle activity was significantly reduced in people with Alzheimer’s disease, while frequency and bandwidth remained preserved. Changes in these oscillations were associated with Alzheimer’s-related and neurodegeneration biomarkers, suggesting a potential electrophysiological marker connecting sleep microarchitecture with disease pathology.

Better age-friendly environments were linked to a lower risk of motoric cognitive risk syndrome in older adults.

Age-Friendly Environments May Reduce Motoric Cognitive Risk

A prospective cohort study of 7,608 older adults found that better age-friendly environments were associated with a lower risk of developing motoric cognitive risk syndrome (MCR), a predementia condition. Over 4 years, participants with the highest AFE scores had a 38% lower MCR risk than those with the lowest scores, supporting age-friendly environments as a potential dementia-prevention strategy.

Miltefosine and liposomal amphotericin B showed promising cure rates for cutaneous leishmaniasis, but stronger evidence is needed.

Systemic Treatments for Cutaneous Leishmaniasis: Cure Rates

A systematic review and meta-analysis of 83 studies involving 4,603 patients found variable cure rates with systemic treatments for cutaneous leishmaniasis. Pooled cure rates were highest with liposomal amphotericin B (77%) and miltefosine (75%), compared with 59% for meglumine antimoniate. However, limited comparative evidence highlights the need for species-specific, high-quality randomized trials.

Non-contrast CT markers may identify patients at high risk of hematoma expansion after factor Xa inhibitor-associated ICH.

CT Markers Predict Hematoma Expansion in Factor Xa-Associated ICH

A post hoc analysis of the ANNEXa-I trial involving 434 patients with factor Xa inhibitor-associated intracerebral hemorrhage found that 72.1% had at least one non-contrast CT marker of hematoma expansion risk. Heterogeneous density, hypodensity, and the black hole sign were independently associated with hematoma expansion, supporting their use for early risk assessment.
