An Impact Assessment Of The Effectiveness Of Utilizing Informal Health Communication Interventions To Spread Health Recommendations And Change Public Perception, Lina Mohamed Ezzat Ahmed Abdel Mawgoud

Theses and Dissertations

Brain health is an increasingly urgent but critically under-addressed public health priority in Egypt and the wider MENA region. Despite its centrality to aging, productivity, and overall quality of life, public understanding of brain health remains limited, and stigma continues to shape responses to dementia and cognitive decline. This study evaluates the effectiveness of informal, culturally adapted health communication as a tool to shift perception, increase awareness, and promote behavior change among non-medically trained adults in Egypt.

Grounded in global evidence on cognitive reserve, neuroplasticity, and the life-course approach to brain health, the intervention translated expert-informed brain health recommendations into …

More Than A Healthcare Issue: Understanding The Breadth Of Occupational Burnout In Our Patients, Aliza Anderson*, Julia Maniccia*, Marc Moss

Marshall Journal of Medicine

Burnout is an occupation-related condition resulting from chronic workplace stress and is associated with significant psychological and physical morbidity. This commentary recognizes burnout as a public health concern across both healthcare and non-healthcare professions, illuminates key occupational risk and protective factors, reviews the biopsychosocial impacts of burnout, and argues for the integration of occupational health screening into clinical practice. A synthesis of the literature highlighted that existing research has focused primarily on healthcare occupations; however, emerging evidence demonstrates an elevated burnout risk in numerous non-healthcare occupations. Characterized by high job demands, limited autonomy, inadequate social support, and physically demanding labor, …

Partial Versus Full Revision In Cementless Single-Stage Exchange For Hip Periprosthetic Joint Infection: A Multicenter Comparative Study With 10-Year Survivorship Analysis, Wenbo Mu, Atthakorn Jarusriwanna, Boyong Xu, Scot A. Brown, Xiaogang Zhang, Alexander Dawes, Javad Parvizi Md, Li Cao

Rothman Institute Papers

BACKGROUND: Periprosthetic joint infection (PJI) is one of the most challenging complications following total hip arthroplasty (THA). Traditional management typically involves full revision to ensure comprehensive infection eradication. However, for patients with well-fixed implants, partial revision in a single-stage cementless approach may provide a viable alternative, potentially preserving bone stock and reducing operative time. The relative efficacy of this approach compared with full revision remains to be fully explored. This multicenter study aims to determine whether partial revision in cementless single-stage exchange surgery offers comparable infection control outcomes to full revision for select patients with well-fixed implants.

METHODS: We conducted …

Background: Whole genome sequence (WGS) data in multi-ancestry samples supports discovery of low-frequency or population-specific genetic variants associated with chronic obstructive pulmonary disease (COPD) and lung function.

Results: We performed single variant, structural variant, and gene-based analysis of pulmonary function (FEV1, FVC and FEV1/FVC) and COPD case-control status in 44,287 multi-ancestry participants from the NHLBI Trans-Omics for Precision Medicine (TOPMed) Program. We validated findings using the UK Biobank and assessed implicated genes using lung single-cell RNA-seq (scRNA-seq) data sets. Applying a genome-wide significance threshold (P < 5 × 10-9), we replicated known loci and identified novel associations near LY86, MAGI1, GRK7, and LINC02668. Colocalization with gene expression quantitative trait loci (eQTL) from the Lung Tissue Research Consortium highlighted known candidate genes including ADAM19, THSD4, C4B, and PSMA4, which were not identified through other eQTL sources. Multi-ancestry analysis improved fine-mapping resolution (e.g., HTR4 and RIN3). Gene-based analysis identified and replicated HMCN1. In human lung scRNA-seq data sets, lung epithelial cells and immune cell types showed enriched expression, while fibroblasts showed higher expression for HMCN1. CRISPR targeting HMCN1 in IMR90 demonstrated reduced expression of collagen genes.

Conclusions: Large-scale multi-ancestry WGS analysis improves variant discovery and fine-mapping resolution for lung function and …

Faculty, Staff and Student Publications

Background: Abnormal levels of VWF (von Willebrand Factor) are a risk factor for venous thromboembolism (VTE) and bleeding. Genome-wide association studies for VWF have identified novel candidate genes that may regulate VWF levels in humans, including RAB5C (RAS-associated protein RAB5C). We hypothesized that RAB5C regulates VWF release from endothelial cells.

Methods: We studied the effect of RAB5C on vesicle trafficking in human endothelial cells. We performed CRISPR (clustered regularly interspaced short palindromic repeats) interference targeting 2 genetic variants linked to altered VWF levels and evaluated RAB5C expression by reverse transcription-quantitative polymerase chain reaction. We silenced RAB5C or overexpressed RAB5C wild-type, …

A263: Exploring Cadd-Based Binding Modes Of Androstenedione And Its Metabolites With Potential In Vivo Targets, Yuhong Ding, Wei Dong

International Journal of Physical Activity and Health

The abuse of androstenedione, an endogenous steroid hormone, among athletes to enhance performance is a significant concern in sports. Current anti-doping detection methods are limited by short detection windows and high false-positive rates, largely due to the transient nature of primary metabolites. To address these challenges, this study employs computer-aided drug design (CADD) to identify stable, long-acting metabolites of androstenedione that can extend the detection window and improve anti-doping efficacy. The integration of CADD with sports physiology principles allows for a more comprehensive understanding of how exercise-induced metabolic fluctuations can influence the detection of these metabolites. Method: Molecular docking simulations …

International Journal of Physical Activity and Health

Based on the FITT-VP principle, this study investigated the dose-response relationship between tennis participation and cardiorespiratory fitness (CRF) in college students. Addressing the current reliance on expert consensus for exercise prescription and the lack of dose-regulation mechanisms, this study focused on high-intensity interval training (HIIT) and sprint interval training (SIT). It aimed to analyze the dynamic relationship and biological mechanisms between exercise intensity (SIT: 80-100% HRmax vs. HIIT: 75-90% HRmax), duration (8 weeks, frequency 2-3 sessions/week), and key CRF indicators (VO2max, anaerobic threshold, and exercise efficiency). Forty healthy college students with similar tennis experience were randomly assigned to HIIT (n=10), …

A097: Intelligent Exercise Prescription Facilitates The Development Path Of Sports For Obese Populations, Qiqi Huang

International Journal of Physical Activity and Health

The global population of individuals is expanding rapidly. By 2024, the obesity rate among adults in China is expected to surge to 16.4%, while globally, over 4 billion people are facing issues of overweight or obesity. Traditional exercise prescriptions suffer from the limitations of "generalized guidance" and "static prescriptions." Studies have shown that due to the neglect of individual metabolic differences, only 20% of individuals can maintain clinically significant weight loss for more than 12 months, and merely 10-25% patients can sustain a weight loss of ≥10% in the long term. The intelligent technology-driven exercise intervention system is reshaping the …
