Novel CO loaded nanoparticle ultrasound-activated contrast agent: A potential urinary catheter-free modality to detect vesicoureteral reflux.

Background: The current gold-standard for detecting vesicoureteral reflux (VUR) is the voiding cystourethrogram (VCUG). However, VCUGs require ionizing radiation and bladder catheterization that can be challenging to perform and traumatic for pediatric patients and their parents.

Objective: To investigate the feasibility of a novel urinary catheter-free modality for diagnosing VUR using in vitro and ex vivo models.

A cross-sectional study characterizing the prevalence of utility service outages across demographic characteristics and health correlates in New York City.

Background: Utility services for electricity, gas, heat, and hot water are necessities for everyday activities (e.g., lighting, cooking, and thermal safety).

Associations Between Social Determinants of Health and Opioid-Use Disorder Among Chronic Pain Patients From a Multi-Institutional Dataset.

Background: This study examined the association between opioid-use disorder (OUD)-related diagnoses (eg, opioid dependence) and social determinants of health (SDoH) among patients with chronic pain.

Methods: A cross-sectional study was performed using the All of Us dataset (including >70,000 patients) to measure associations between SDoH and OUD using population- and individual-level surveys. Mixed-effects multivariable regression models (random effect being zip code) were conducted for each of the key SDoH domains.

Vaping nicotine and cannabis on the same occasion is linked to increased vaping consumption among young adults: A smartphone-based daily diary study.

Significance: Vaping both nicotine and cannabis in the past 30 days (co-vaping) is common among young adults. It is unclear which co-vaping patterns may increase substance use and dependence. We examined day-level associations between vaping patterns with vaping quantity.

White matter hyperintensities and headache in United States military veterans with mild traumatic brain injury.

Objective: The objective of this study was to examine the association between white matter hyperintensities and migraine-like headache in United States military veterans with a history of mild traumatic brain injury.

Background: White matter hyperintensities on magnetic resonance imaging (MRI) may be associated with migraine; however, little is currently known about the relationship between white matter hyperintensities and headache following mild traumatic brain injury in military veterans.

Methods: This cross-sectional study consisted of a retrospective chart review of veterans from a Southeastern Department of Veterans Affairs polytrauma clinic who had a verified history of mild traumatic brain injury.
