Healthcare Access Barriers in Aging: How Financial and Structural Constraints Drive Worse Outcomes
Cost-related medication nonadherence, missed appointments, and care fragmentation each independently increase hospitalization and mortality in older adults. This article reviews the evidence on access barriers and what interventions actually move outcomes.

Nocturnal Blood Pressure Non-Dipping: The Hidden Cardiovascular Risk You Can Measure
Blood pressure normally falls 10–20% during sleep. When this nocturnal dip is absent, cardiovascular and renal risk increase substantially — even if daytime readings appear normal. This article explains the mechanism and evidence-based management strategies.

Orthostatic Intolerance in Aging: Causes, Risks, and Evidence-Based Management
Orthostatic intolerance — dizziness or near-fainting upon standing — affects up to 20% of adults over 65 and substantially increases fall risk. This article reviews the mechanisms and evidence-based management strategies.

Sodium-Potassium Balance in Aging: The Dietary Lever for Blood Pressure and Vascular Health
The ratio of dietary sodium to potassium is a more powerful predictor of cardiovascular risk than sodium intake alone. This article reviews the evidence for the Na/K balance as a therapeutic target and practical approaches to correction.

VO2max and Cardiorespiratory Fitness: Why It Predicts Longevity and How to Improve It
VO2max is one of the strongest independent predictors of all-cause mortality. This review covers what VO2max measures, how it declines with age, and the training protocols with the best evidence for improving it.
