Aromatase inhibitor use, co-morbidities, and cardiovascular disease risk in breast cancer survivors

Breast cancer survivors are a growing population with significant comorbidity burden. Approximately 80 percent of breast cancer cases are hormone receptor-positive and can be treated by endocrine therapy. Aromatase inhibitors (AIs) and tamoxifen are the two major types of endocrine therapies. Although AIs have more favorable breast cancer clinical outcomes than tamoxifen, AI-related cardiovascular disease…


Observational epidemiology for evaluating respiratory virus vaccine impact using population surveillance data

Observational studies of vaccine preventable diseases (VPDs) are needed to answer questions not addressed by clinical trials and inform policy decisions. In addition, data from community, rather than clinical, settings are essential as clinical surveillance largely does not capture individuals at low risk for severe disease and may not be representative of subclinical disease. Also,…


Morbidity, mortality, and gut virome ecology of Kenyan children exposed to versus not exposed to maternal HIV

Mother-to-child transmission of HIV has decreased rapidly with the expansion of optimized antiretroviral therapy (ART) regimens for all individuals living with HIV, resulting in a growing population of children who are HIV-exposed but uninfected (CHEU). Historically, CHEU have experienced greater morbidity and mortality than children who are HIV-unexposed uninfected (CHUU). The etiology of these differences…

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…


Inequities in access to mental health care at intersections of race/ethnicity, gender identity, and gender modality: An application of Multilevel Analysis of Individual Heterogeneity and Discriminatory Accuracy (MAIHDA)

Transgender populations, and particularly transgender women of color, are burdened by high rates of both mental illness and healthcare avoidance. Despite this, research examining the patterns of non-use of mental healthcare within this community is lacking, and has further suffered due to the difficulty of collecting large, population-based samples of transgender adults in general, and…
