Purpose: Evaluation and comparison of outcomes following gender-affirming mastectomy have been hindered by the lack of a validated population- and surgery-specific patient-reported outcome measure (PROM). The purpose of this study was to explore the lived experiences of transgender individuals assigned female at birth (AFAB) from before-to-after gender-affirming mastectomy to identify key qualitative themes that might inform the creation of a quantitative PROM in the future.

Methods: Identified candidates were transgender men AFAB, 18-65 years of age (mean±standard deviation: 30.

Article Synopsis
  • Spatial navigation is an essential skill affected by vestibular and hearing impairments, which are under-researched in this context.
  • The study analyzed data from 182 participants, using various tests to evaluate the impact of these impairments on navigation performance.
  • Results indicated that while vestibular dysfunction (measured by oVEMP) correlated with increased navigation errors, hearing impairment was specifically linked to shorter walking distances; however, there was no interaction effect between vestibular and hearing function on navigation ability.

Not all dizziness presents as vertigo, suggesting other perceptual symptoms for individuals with vestibular disease. These non-specific perceptual complaints of dizziness have led to a recent resurgence in literature examining vestibular perceptual testing with the aim to enhance clinical diagnostics and therapeutics. Recent evidence supports incorporating rehabilitation methods to retrain vestibular perception.

Background: Unilateral peripheral vestibular hypofunction can result in symptoms of dizziness, gaze and gait instability, and impaired navigation and spatial orientation. These impairments and activity limitations may negatively impact an individual's quality of life, ability to perform activities of daily living, drive, and work. There is strong evidence supporting vestibular physical therapy for reducing symptoms, improving gaze and postural stability, and improving function in individuals with vestibular hypofunction.

Wearing a facemask (FM) reduces the spread of COVID-19, but it also blocks a person's lower visual field. Many new public safety rules were created in response to COVID-19, including mandated FM wearing in some youth sports like youth ice hockey. We hypothesized that FM wearing in youth hockey players obstructs the lower field of view and may impact safety.

Background: Uncompensated vestibular hypofunction can result in symptoms of dizziness, imbalance, and/or oscillopsia, gaze and gait instability, and impaired navigation and spatial orientation; thus, may negatively impact an individual's quality of life, ability to perform activities of daily living, drive, and work. It is estimated that one-third of adults in the United States have vestibular dysfunction and the incidence increases with age. There is strong evidence supporting vestibular physical therapy for reducing symptoms, improving gaze and postural stability, and improving function in individuals with vestibular hypofunction.

Spatial cognition is the process by which individuals interact with their spatial environment. Spatial cognition encompasses the specific skills of spatial memory, spatial orientation, and spatial navigation. Prior studies have shown an association between psychometric tests of spatial ability and self-reported or virtual measures of spatial navigation.

Objectives: Given earlier effects found in randomized clinical trials of the Nurse-Family Partnership, we examined whether this program would improve 18-year-old first-born youths' cognition, academic achievement, and behavior and whether effects on cognitive-related outcomes would be greater for youth born to mothers with limited psychological resources (LPR) and on arrests and convictions among females.

Methods: We enrolled 742 pregnant, low-income women with no previous live births and randomly assigned them to receive either free transportation for prenatal care plus child development screening and referral (control; = 514) or prenatal and infant home nurse visit (NV) plus transportation and screening ( = 228). Assessments were completed on 629 18-year-old first-born offspring to evaluate these primary outcomes: (1) cognitive-related abilities (nonverbal intelligence, receptive language, and math achievement) and (2) behavioral health (internalizing behavioral problems, substance use and abuse, sexually transmitted infections, HIV risk, arrests, convictions, and gang membership).

Background: Prenatal and infancy home-visiting by nurses is promoted as a means of improving maternal life-course, but evidence of long-term effects is limited. We hypothesized that nurse-visitation would lead to long-term reductions in public-benefit costs, maternal substance abuse and depression, and that cost-savings would be greater for mothers with initially higher psychological resources.

Methods: We conducted an 18-year follow-up of 618 out of 742 low-income, primarily African-American mothers with no previous live births enrolled in an randomized clinical trial of prenatal and infancy home visiting by nurses.

Objective: The present study was designed to determine whether healthy older adults with age-related vestibular loss have deficits in spatial navigation.

Methods: 154 adults participating in the Baltimore Longitudinal Study of Aging were tested for semicircular canal, saccular, and utricular function and spatial navigation ability using the blindfolded Triangle Completion Test (TCT). Multiple linear regression was used to investigate the relationships between each measure of vestibular function and performance on the TCT (angular error, end point error, and distance walked) while controlling for age and sex.

Background: Oculomotor impairments, dizziness, and imbalance are common after sports-related concussion (SRC) in adolescents and suggest a relationship between SRC and vestibular system dysfunction. However, it is not clear whether the source of these problems is attributable to the peripheral or central vestibular system.

Hypothesis: The video Head Impulse Test (vHIT), which assesses peripheral vestibular function, will show differences in gain between adolescents with and without SRC.
