Nursing home and end-of-life care in Parkinson disease.

Objective: To examine long-term care facility (LTCF or nursing home) use and end-of-life care for individuals with Parkinson disease (PD).

Methods: In this nationwide retrospective cohort study, we compared LTCF and hospice utilization among Medicare beneficiaries diagnosed with PD by demographic, clinical, and physician characteristics. We also examined the impact of outpatient neurologist care for institutionalized patients with PD on end-of-life care.

This article is part of a Special Issue "Energy Balance". Natural populations display a variety of reproductive responses to environmental cues, but the underlying physiology that causes these responses is largely unknown. This study tested the hypothesis that heritable variation in reproductive traits can be described by heritable variation in concentrations of hormones critical to both energy balance and reproduction.
