Association of Neighborhood-Level Socioeconomic Status With Prolapse Management Decision.

IMPORTANCE: This study identifies how neighborhood-level socioeconomic status (SES) may affect patients' treatment decisions for pelvic organ prolapse (POP). OBJECTIVE: This study aimed to evaluate the association of neighborhood-level SES with the decision of surgical versus conservative POP management. STUDY DESIGN: This was a retrospective cohort study of patients newly diagnosed with POP at a tertiary medical center between 2015 and 2021. Patients lost to follow-up or poor surgical candidates were excluded. Patient characteristics, demographics, and treatment selection were abstracted from the electronic health record. Conservative management was defined as expectant, pessary, and/or pelvic floor physical therapy. Five-digit zip codes were linked to the Area Deprivation Index and used as a surrogate for neighborhood-level SES. Area Deprivation Indices were dichotomized at or below the sample median (less disadvantaged area) and above the sample median (more disadvantaged area). Logistic regression models estimated the odds of choosing surgical versus conservative management as a function of the Area Deprivation Index. RESULTS: A total of 459 patients met the eligibility criteria (non-Hispanic White, 88.2%). The median age was 63 years (interquartile range, 52-70 years), and the majority had stage 2 POP (65.7%). Of all patients, 59.3% had Medicare/Medicaid, 39.9% were privately insured, and 0.9% were uninsured. Furthermore, 74.7% selected surgical management, and 25.3% chose conservative management. Increasing age and higher Pelvic Organ Prolapse Quantification System stage were significantly associated with selecting surgery (P = 0.01). Women residing in a more disadvantaged area had a 67% increased odds of choosing surgical over conservative management (adjusted odds ratio, 1.67; 95% confidence interval, 1.06-2.64) after adjusting for age, race/ethnicity, body mass index, and Pelvic Organ Prolapse Quantification System stage. CONCLUSIONS: Residing in a more disadvantaged zip code was associated with 67% increased odds of choosing surgical versus conservative POP management.

Longer Duration of Downslope Treadmill Walking Induces Depression of H-Reflexes Measured during Standing and Walking.

OBJECTIVES: The Hoffman-reflex (H-reflex) is an electrophysiological technique used to evaluate the excitability of the monosynaptic spinal reflex arc. In individuals with upper motor neuron lesions who show elevated spinal excitability, a depression of spinal excitability may indicate adaptive spinal plasticity. Downslope walking (DSW), an exercise intervention comprising repetitive eccentric muscle activity, has been shown to induce depression of soleus H-reflex amplitudes while seated, however, the dose-response time-course of H-reflex modulation during DSW has not been characterized. The objectives of this study were twofold: (1) to evaluate DSW-induced soleus H-reflex depression in the standing posture and during walking, and (2) to investigate the effect of walking duration (20 minutes and 40 minutes) of DSW (-15% decline) on soleus H-reflexes, (with level walking (LW) as a control intervention). METHODS: Soleus H-reflexes were collected Pre, Post-20 minutes, and Post-40 minutes of walking in the standing position; and H-reflexes were also measured at 4 different time points during the terminal stance phase of walking. RESULTS: Our results showed that soleus H-reflexes evaluated in standing showed a greater % depression after DSW compared to LW, with a statistical trend for greater depression with longer durations (40-minutes). H-reflexes measured during walking showed greater depression after 40 minutes of walking compared to 20- or 30-minutes for both DSW and LW. CONCLUSIONS: Longer duration treadmill walking (40-minutes) may induce a greater acute depressive effect on soleus H-reflex excitability compared to shorter durations (20-minutes) of treadmill walking. Future work will investigate the potential for DSW as a gait training intervention in people with upper motor neuron lesions such as multiple sclerosis and stroke.
