Transcriptomic advances in studies of muscle stem cell aging: From bulk to single-cell and beyond
Advances in transcriptomic technologies have progressively transformed the questions we can ask and answer about muscle stem cells (MuSCs) during aging. Early microarray and bulk RNA sequencing studies established foundational population-level signatures of aged MuSCs, including attenuation of myogenic and metabolic programs as well as induction of inflammatory and stress-associated transcription. However, these averaged readouts obscured cell-to-cell variability and rare functional states. The...

Older Americans' Attitudes Toward Caregiving Cost Responsibility and Long-Term Care Access and Costs by Caregiver Status
CONCLUSIONS: Most older Americans are concerned about access to long-term care and costs, yet remain divided on who primarily should pay for caregiving costs. Caregivers are both more concerned about long-term care access and more likely to support the government's primary responsibility for caregiving costs than noncaregivers. Policymakers should consider more options for access to affordable, high-quality long-term care, and financial supports for caregivers.
Immunosenescence and its impact on ischemic stroke risk and outcomes in older adults: a systematic review
CONCLUSION: Immunosenescence plays a crucial role in IS pathogenesis and recovery, with chronic inflammation and immune dysfunction exacerbating stroke outcomes in older adults. Targeting immune markers, particularly IL-6 and the Th17/Treg imbalance, may offer new therapeutic approaches to improve stroke prognosis in aging populations. Further research is needed to develop interventions that address immunosenescence in IS.
Nightly variations in sleep quality and next-day cognitive performance: an in-home study in healthy older adults
INTRODUCTION: Sleep quality is often thought to be a key determinant of cognitive performance, particularly in older adults who experience age-related changes in sleep architecture. However, the extent to which nightly variations in sleep quality impact next-day cognitive performance remains unclear-in part because it has only recently become practical to measure sleep over multiple nights.
