Optimizing the Placement of Automated External Defibrillators in Marin County, CA — A Location-Allocation Analysis

This study evaluated the spatial and temporal coverage of public automated external defibrillators (AEDs) in Marin County, California, from 2019 to 2024 to determine whether existing AEDs were optimally located to maximize Out-of-hospital cardiac arrest (OHCA) coverage and to identify additional placement opportunities. We defined coverage as the proportion of OHCAs occurring within 100 meters…


Factors Associated with Latent Tuberculosis Treatment Initiation for Primary Care Patients in a Large Health System

Background: One of the mainstays of eliminating tuberculosis as a public health threat is through the treatment of latent tuberculosis infections (LTBI). To determine ways to improve LTBI treatment rates, we assessed factors associated with LTBI treatment initiation in United States (US)-based primary care clinics. Methods: Using electronic health record data, we identified adult primary…


Pediatric Oncology and Bone Marrow Transplant ICU Patients in Children’s and General Hospitals

Pediatric oncology and hematopoietic stem cell (HCT) care in the US is increasingly provided at children’s hospitals (CH), but many children still receive care at general hospitals (GH). Little is known about the characteristics of pediatric oncology and HCT patients treated in intensive care units (ICUs) at these institutions, or how outcomes differ for patients…


Receipt of Glucagon-Like Peptide-1 Receptor Agonists Among rural Patients with Obstructive Sleep Apnea and Excess Weight

Successful weight loss is more difficult for those with OSA, and gaps in weight management care are more pronounced in rural areas. Glucagon-Like Peptide-1 Receptor Agonists (GLP-1RAs) are promising agents to improve the effectiveness of weight management care patients with OSA and excess weight living in rural areas. We sought to test the association of…

Transition of Care Readiness Among Adolescents with Chronic Pain Between 2021-2022 in a Nationally Representative Sample

Chronic pain impacts 11-33% of children and will continue into adulthood for over half of them. Transition of pain management to adult care is crucial given high risk of interruption of care which is associated with subsequent poor medical, social, and vocational outcomes. Yet the transition experience for these youth is poorly characterized. We aimed…


Mobility Patterns, Activity Spaces, and Tuberculosis in Nairobi, Kenya

Background: Tuberculosis (TB) remains one of the leading infectious causes of morbidity and mortality globally. Annually, over 3 million people develop TB but are not diagnosed and not initiated on treatment. This case-detection gap critically impedes global efforts to end the TB epidemic, as individuals with undiagnosed TB may be contributing to ongoing transmission. Active…


The Impact of the Choosing Wisely Campaign Recommendations on Supplemental Oxygen Management

Passive dissemination of information is commonly used to influence clinical practice. Our objective was to assess whether passive dissemination of the Choosing Wisely Campaign recommendations to reassess hypoxemia before renewing post-discharge supplemental oxygen impacted receipt of oxygen reassessment or oxygen appropriateness. We conducted a cohort study of all patients with inpatient COPD exacerbation at a…


The Diagnosis of Invasive Aspergillosis Using Screening Detection of Aspergillus Galactomannan After Hematopoietic stem cell transplant.

Early detection of invasive aspergillosis (IA) in hematopoietic stem cell transplant (HSCT) patients is crucial and requires early initiation of antifungal therapy. One method that has been suggested as a means for early detection of aspergillosis is serum Aspergillus galactomannan (GM) detection. However, there have been few formal evaluations of the performance of GM screening…
