Article Synopsis
  • Nocturnal lower urinary tract symptoms, like nocturia and nocturnal enuresis, could help screen for obstructive sleep apnea (OSA) in patients at urogynecology clinics.
  • The study assessed how effective these symptoms are in identifying OSA, using a retrospective analysis of patients screened through established questionnaires and OSA testing.
  • Results showed that nocturia (≥2 episodes per night) has good sensitivity (86.4%) and fair specificity (58.5%) for OSA screening, while nocturnal enuresis showed lower overall effectiveness, indicating that nocturia is more reliable for clinical decision-making regarding OSA referrals.

The COVID-19 pandemic disrupted all aspects of life globally and laid bare the pervasive inequities in access to education, employment, healthcare and economic security in both high-resource and low-resource settings. The global health field's brittle attempts of addressing global health inequities, through efforts that in some cases have evoked the colonialist forces implicated in shaping these disparities, have been further challenged by the pandemic. COVID-19 has forced global health leaders to reimagine their field through innovation such as shifting the application of global health to a local focus, collaborating with community organisations and exploring virtual education technologies.

Background: Surgical repair has a transformative impact on the lives of women affected by female genital fistula; however, various physical, social, and economic challenges may persist postrepair and prevent complete reengagement in relationships and communities. Nuanced investigation of these experiences is needed to inform programming that aligns with women's reintegration needs.

Aim: We investigated the sexual activity resumption, experiences, and concerns of women in Uganda during the year following genital fistula repair surgery.

Introduction And Hypothesis: Educational interventions have been effective in improving postpartum knowledge, performance of pelvic floor exercises, and bowel-specific quality-of-life. Our primary objective was to determine if a video-based educational intervention on pelvic floor disorders (PFDs) would increase Spanish-speaking women's knowledge of PFDs, and secondarily to assess if it would decrease pelvic floor symptoms. We hypothesized that Spanish-speaking women would improve their pelvic floor knowledge and symptoms post-intervention.
