Adherence to the ambulatory peritoneal dialysis procedure and limitations of care of older adults or their caregivers.

Background: Continuous Ambulatory Peritoneal Dialysis is an appropriate technique for older adults and its success is mainly based on the correct exchange technique. However, individuals may present barriers to compliance, due to deterioration of physical and cognitive function, depression, and prevalence of visual impairments.

Objective And Methodology: A descriptive correlational study was conducted to determine the relationship between adherence to the continuous ambulatory peritoneal dialysis procedure and the limitations of care for older adults with chronic renal failure or their caregivers.

Depressive Symptoms are Associated with low Serotonin Levels in Plasma but are not 5-HTTLPR Genotype Dependent in Older Adults.

Depressive symptoms are diagnosed by physicians using scales but their pathophysiology is unclear. Low serotonin (5-HT) levels play an important role in depression, and the 5-HT transporter (5-HTT) is an important regulator of plasma serotonin levels and reuptake. Additionally, the 5-HTT gene-linked polymorphic region (5-HTTLPR) is associated with depression.

Factors Contributing to Active Aging in Older Adults, from the Framework of Roy's Adaptation Model.

Objectives: To determine the variables contributing to the explanation of active aging according to Roy's adaptation model.

Methods: Descriptive correlational study, with convenience and snowball sampling. Two hundred older adults with chronic disease, were included.

A physical-cognitive intervention to enhance gait speed in older Mexican adults.

Purpose: To test the effects of a physical-cognitive exercise intervention on gait parameters under dual-task conditions in community-dwelling older adults.

Design: A repeated-measures quasi-experimental design, with control and exercise groups, was used.

Setting: Study participants consist of a convenience sample recruited from senior citizens' centers in Monterrey, Mexico.
