AI Article Synopsis

  • The study examines how nursing care impacts sleep and wake states in preterm infants, comparing results by gender.
  • At 34 weeks postmenstrual age, there were no significant differences in sleep and wake states between male and female infants, but male infants showed a much higher rate of state change.
  • By discharge, male infants experienced nearly twice as much caregiving and had a greater response in state change to that caregiving compared to females, indicating potential gender differences that warrant further investigation.

Article Abstract

Purpose: To describe the effect of nursing caregiving on infant sleep-wake states by gender in preterm infants.

Design: Descriptive measures at 34 weeks postmenstrual age and at discharge.

Sample: Twenty-two hospitalized preterm infants.

Main Outcome Variable: Infant state and caregiving episodes were coded in 15-second intervals from video recordings of approximately three hours duration. Time plots of state and caregiving were analyzed visually to summarize spontaneous state changes and state change associated with caregiving.

Results: Sleep and wake state distribution did not differ statistically by gender; however, the rate of state change in male infants was twice that of females (p=.012) at discharge. At discharge, male infants received approximately twice as many care episodes as females. At discharge, the rate of state change in response to caregiving in male infants was four times that of female infants (p=.026). Males exhibited a greater percentage of caregiving episodes related to state change than did females at discharge (p=.018). Findings suggest further exploration of possible gender differences in state regulation and state change in response to caregiving.

Neural effects of memory training to reduce false memories in older adults: Univariate and multivariate analyses.

Neurobiol Aging

January 2025

Department of Psychology, The Pennsylvania State University,  University Park, PA 16802, United States. Electronic address:

The growing population of older adults emphasizes the need to develop interventions that prevent or delay some of the cognitive decline that accompanies aging. In particular, as memory impairment is the foremost cognitive deficit affecting older adults, it is vital to develop interventions that improve memory function. This study addressed the problem of false memories in aging by training older adults to use details of past events during memory retrieval to distinguish targets from related lures.

Sclerosis is a highly morbid manifestation of chronic GVHD (cGVHD), associated with distressing symptoms and significant long-term disability. A patient-reported outcome measure (PRO) for cGVHD-associated sclerosis is essential to advance therapeutic trials. We aimed to develop a PRO for adults with cGVHD-associated sclerosis and evaluate and refine its content validity.

Acceptance, Safety, and Effect Sizes in Online Dialectical Behavior Therapy for Borderline Personality Disorder: Interventional Pilot Study.

JMIR Form Res

January 2025

Department of Psychosomatic Medicine and Psychotherapy, Central Institute of Mental Health, Medical Faculty Mannheim, Heidelberg University, Mannheim, Germany.

Background: The potential of telehealth psychotherapy (ie, the online delivery of treatment via a video web-based platform) is gaining increased attention. However, there is skepticism about its acceptance, safety, and efficacy for patients with high emotional and behavioral dysregulation.

Objective: This study aims to provide initial effect size estimates of symptom change from pre- to post treatment, and the acceptance and safety of telehealth dialectical behavior therapy (DBT) for individuals diagnosed with borderline personality disorder (BPD).
