Epidemiology And Pathophysiology Of Common Skin Diseases In West Africa: An Immunodermatological Framework, Osazomon Imarenezor

All HCAS Student Capstones, Theses, and Dissertations

This capstone reviews the common skin diseases on a global scale. With these dermatoses being further funneled into Africa and then magnified into common West African dermatoses, the meta-analyses of literature available paints a clear picture of the epidemiological & pathological factors and their contribution to the skin disease. Each article analysed in this analysis was taken from a 20-year span of January 2000 to December 2019. The selection of articles was fine-tuned by identifying the distribution of skin disease, revealing the populations affected (age, gender, ethnicity, etc), the main causes, country of origin, the prognosis of disease, and the …

Availability and affordability of blood pressure lowering drugs, antiplatelets and statins were obtained from pharmacies. Participants were categorised: group 1-all three drug types …

A Hybrid Agent-Based And Equation Based Model For The Spread Of Infectious Diseases, Elizabeth Hunter, Brian Mac Namee, John D. Kelleher

Articles

Both agent-based models and equation-based models can be used to model the spread of an infectious disease. Equation-based models have been shown to capture the overall dynamics of a disease outbreak while agent-based models are able to capture heterogeneous characteristics of agents that drive the spread of an outbreak. However, agent-based models are computationally intensive. To capture the advantages of both the equation-based and agent-based models, we create a hybrid model where the disease component of the hybrid model switches between agent-based and equation-based. The switch is determined using the number of agents infected. We first test the model at …

Plasma Proteins That May Cause Parkinson’S Disease And Multiple Sclerosis: A Mendelian Randomization Study, Brigid A. Staley

Dissertations and Theses

Multiple sclerosis (MS) and Parkinson’s disease (PD) are progressively disabling neurologic disorders that profoundly affect quality of life and shorten life expectancy. There is no cure for either disease, and current treatments only alleviate symptoms and may cause serious side effects. The causes of MS and PD are not well understood. Previous epidemiologic studies have documented numerous environmental risk factors for both diseases. However, these studies are inherently prone to bias from confounding which may generate spurious results. The lack of unbiased evidence on environmental causes of MS and PD has been a critical barrier to fully understanding their pathophysiology. …

Epidemiological Profile And Transmission Dynamics Of Covid-19 In The Philippines, Nel Jason L. Haw, Jhanna Uy, Karla Therese L. Sy, M.R.M Abrigo

Health Sciences Faculty Publications

The Philippines confirmed local transmission of COVID-19 on 7 March 2020. We described the characteristics and epidemiological time-to-event distributions for laboratory-confirmed cases in the Philippines recorded up to 29 April 2020 and followed until 22 May 2020. The median age of 8212 cases was 46 years (IQR 32–61), with 46.2% being female and 68.8% living in the National Capital Region. Health care workers represented 24.7% of all detected infections. Mean length of hospitalisation for those who were discharged or died were 16.00 days (95% CI 15.48–16.54) and 7.27 days (95% CI 6.59–8.24). Mean duration of illness was 26.66 days (95% …

Optimism And Risk Of Incident Hypertension: A Target For Primordial Prevention, Laura D. Kubzansky, Julia K. Boehm, Andrew R. Allen, Loryana L. Vie, Tiffany E. Ho, Claudia Trudel-Fitzgerald, Hayami K. Koga, Lawrence M. Scheier, Martin E. P. Seligman

Psychology Faculty Articles and Research

Aims

Optimism is associated with reduced cardiovascular disease risk; however, few prospective studies have considered optimism in relation to hypertension risk specifically. We investigated whether optimism was associated with a lower risk of developing hypertension in U.S. service members, who are more likely to develop high blood pressure early in life. We also evaluated race/ethnicity, sex and age as potential effect modifiers of these associations.

Methods

Participants were 103 486 hypertension-free U.S. Army active-duty soldiers (mean age 28.96 years, 61.76% White, 20.04% Black, 11.01% Hispanic, 4.09% Asian, and 3.10% others). We assessed optimism, sociodemographic characteristics, health conditions, health behaviours and …

Understanding Covid-19: From Origin To Potential Therapeutics, Muhammad Moazzam, Muhammad Imran Sajid, Hamza Shahid, Jahanzaib Butt, Irfan Bashir, Muhammad Jamshaid, Amir Nasrolahi Shirazi, Rakesh Kumar Tiwari

Pharmacy Faculty Articles and Research

Currently, a global pandemic era of public health concerns is going on with the Coronavirus Disease 2019 (COVID-19), which is caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). The first case of COVID-19 was reported from Wuhan’s Huanan seafood market in China late December 2019. Bats, pangolins, and snakes have been nominated as salient carriers of the virus. Thanks to its high pathogenicity, it can cause severe respiratory infections. Fever, dry cough, sore throat, pneumonia, septic shock, and ground-glass opacities are the foremost clinical manifestations of COVID-19. Immunocompromised patients are at high risk for COVID-19 infection and may lead to …

Associations Of Sickness Absence For Pain In The Low Back, Neck And Shoulders With Wider Propensity To Pain, David Coggon, Georgia Ntani, Karen Walker-Bone, Vanda E. Felli, Raul Harari, Lope H. Barrero, Sarah A. Felknor, Marianela Rojas, Anna Cattrell, Muhammad Masood Kadir

Community Health Sciences

Objectives: To explore the association of sickness absence ascribed to pain at specific anatomical sites with wider propensity to musculoskeletal pain.
Methods: As part of the CUPID (Cultural and Psychosocial Influences on Disability) study, potential risk factors for sickness absence from musculoskeletal pain were determined for 11 922 participants from 45 occupational groups in 18 countries. After approximately 14 months, 9119 (78%) provided follow-up information about sickness in the past month because of musculoskeletal pain, including 8610 who were still in the same job. Associations with absence for pain at specific anatomical sites were assessed by logistic regression and summarised …

A Model For The Spread Of Infectious Diseases In A Region, Elizabeth Hunter, Brian Mac Namee, John D. Kelleher

Articles

In understanding the dynamics of the spread of an infectious disease, it is important to understand how a town’s place in a network of towns within a region will impact how the disease spreads to that town and from that town. In this article, we take a model for the spread of an infectious disease in a single town and scale it up to simulate a region containing multiple towns. The model is validated by looking at how adding additional towns and commuters influences the outbreak in a single town. We then look at how the centrality of a town …

Non-Tuberculous Mycobacterial Infections-A Neglected And Emerging Problem, Imran Ahmed, Simon Tiberi, Joveria Farooqi, Kauser Jabeen, Dorothy Yeboah-Manu, Giovanni Battista Migliori, Rumina Hasan

Department of Pathology and Laboratory Medicine

Non-tuberculous mycobacteria (NTM) are ubiquitous dwellers of environmental niches and are an established cause of natural and nosocomial infections. The incidence of NTM infections is rising owing to a growing population of immunocompromised and vulnerable individuals, complex medical and surgical procedures, as well as increased awareness and diagnostic capabilities. The prevalence of different NTM varies between continents, regions, and countries. The true global burden of pulmonary and extrapulmonary disease is unknown and estimates are subject to under and/or over-estimation. Diagnosis requires confirmation by isolation of NTM along with clinical and radiological criteria, which may be suboptimal at all levels. Susceptibility …

Prevalence Of The Hypervirulent Nap1/Bi/027 Strain Of C. Difficile In Southwestern Virginia And Risk Factors Associated With Infection, Andrew O. Hanna, Anthony Baffoe-Bonnie, Shikha Vasudeva

Graduate Medical Education (GME) Resident and Fellow Research Day Posters

C. difficile infection (CDI) incidence has increased over the last several decades. The BI/NAP1/027 ribotype was discovered in 2005 and has since been responsible for multiple outbreaks in the US and Canada. This subtype of C. Difficile is known to be more virulent in vivo and produce more severe disease. Limited regional data of the prevalence of this ribotype is available, which could help guide treatment. Using infection control data from a large regional hospital and a VA medical center, this study documented the prevalence of the 027 ribotype in Southwest Virginia. Patients were included if they were tested at …

Tick-Borne Infections In New Hampshire: An Evaluation Of The Diagnostic Process In A Local Patient Population, Katherine Anderson

Honors Theses and Capstones

Overall, approximately 95 percent of reported cases of vector-borne disease were associated with ticks, making these the most medically important group of arthropods in the United States.¹ Despite the prevalence of tick-borne infections, the process for the diagnosis of this condition is not well studied. This study aims to analyze data from a pool of 100 patients who underwent testing for tick-borne disease in the same institution in Dover, New Hampshire during the most recent peak tick season of 2019. Information utilized in this study included: patient age, sex, location of testing (inpatient versus outpatient), diagnostic testing methods used …

Exposure To Household Secondhand Smoke Among Adolescents In Kuwait: Results From Two School-Based Cross-Sectional Studies, Ali H. Ziyab, Mohammad Almari, Abdullah Al-Taiar

Community & Environmental Health Faculty Publications

INTRODUCTION: Detrimental effects of secondhand smoke (SHS) exposure are well established; however, data on SHS exposure among adolescents in Kuwait are lacking. Hence, this study sought to estimate the prevalence of household SHS exposure among two samples of adolescents in Kuwait and assess its variation by socioeconomic status and parental education level.

METHODS: Data from two large school-based cross-sectional studies were analyzed. Adolescents attending public middle (n=3864; aged 11-14 years) and high (n=1959; aged 14-19 years) schools throughout Kuwait were enrolled in 2016-2017, and parental self-reported household SHS exposure was ascertained. Associations were assessed using Poisson regression with robust variance …
