Faculty, Staff and Student Publications

Hypoxia-inducible factors (HIFs) promote lung protection and pathogen eradication during acute lung injury. We therefore tested the theory that pharmacologic stabilization of HIFs dampens lung injury during SARS-CoV-2 pneumonia. Initial studies in murine SARS-CoV-2 models showed improved outcomes after treatment with the FDA-approved HIF-stabilizer vadadustat. Subsequent studies in genetic models implicated alveolar-expressed Hif1a in mediating lung protection. Therefore, we performed a randomized, double-blinded, multicenter phase 2 trial in patients admitted for SARS-CoV-2 infection and concomitant hypoxia (SpO2 ≤ 94%). Patients (n=448) were randomized to oral vadadustat (900 mg/day) or placebo for up to 14 days. Safety events were similar between …

Beyond The Genome: The Racialized Exposome, Flourishing, And Stress Biology In African Americans, A Non-Exhaustive Review, Enye Washington

University Honors Theses

Racial health disparities remain an enduring challenge in the United States, disproportionately impacting African American communities through higher rates of chronic disease and premature mortality. This non-exhaustive literature explores how the racialized exposome - a term denoting the totality of social, environmental, and structural stressors rooted in systemic racism - biologically embeds itself via stress-responsive pathways. Specifically, it examines the interaction between racial stress, flourishing, and key biological markers, including allostatic load and telomere length, considering the gut-brain axis. The review highlights robust evidence that chronic exposure to racial discrimination and structural adversity contributes to multisystem dysregulation and accelerated cellular …

Articles

Abstract

The rapidly increasing prevalence of myopia and its association with vision-threatening complications in later life has intensified efforts to identify treatments that can prevent the onset and slow the progression of myopia in children. These efforts have led to the development of several optical, environmental, and pharmacological myopia control treatments. Investigations of additional treatment options are ongoing and have shown great promise for clinical translation. Although significant progress has been made in identifying potential pathways and modes of action of these treatments, a complete mechanistic understanding is still lacking. This critical review article explores the potential mechanisms underlying the …

Data on the burden and determinants of mental and substance use problems among women in urban and rural informal settlements in Kenya is sparse, thus limiting preventive and treatment efforts in these areas. To bridge the gap, we (a) determined the prevalence of depressive, anxiety and post-traumatic stress disorder (PTSD) symptoms and alcohol and drug use problems among women compared to their spouses and (b) examined the correlates of these outcomes. Data collection for this cross-sectional survey was conducted in 2022 in Mombasa, Kwale and Nairobi counties in Kenya. A total of 1528 adults (1048 women) took part. The 9-Item …

Mechanisms Of Interventions Targeting Modifiable Factors For Dementia Risk Reduction, Anna Matton, Ruth Stephen, Makrina Daniilidou, Mariagnese Barbera, Vilma Alanko, Marcel Ballin, Jamie Ford, Katri Hemiö, Jenni Lehtisalo, Chinedu Momoh

Brain and Mind Institute

The global prevalence of dementia is increasing. With no widely available and accessible treatments to halt or reverse the progression of dementia, exploring preventative strategies is critical. Lifestyle-based interventions show promise in preventing or delaying dementia onset. However, understanding the complex and multifactorial mechanisms underlying dementia, and how interventions target these pathways, is essential for developing personalized and effective strategies. In this review, we examined the current evidence of the mediating pathways in dementia risk reduction. We focused on mechanisms investigated in single-domain interventions on physical exercise, cognitive training, diet, metabolic/cardiovascular or psycho-social risk factors in line with those combined …
