The Effects Of Outdoor Air Pollutants On The Costs Of Stroke Hospitalizations In China, Siyu Zeng, Luo Li, Fang Chen

Transactions of the International Conference on Health Information Technology Advancement

Stroke, the most frequent cause of severe disability and the second cause of death among adults in the world, brings tremendous mental and economic burden to patients and their families. Emerging evidence indicates that the air pollution mixture contributes to strokes. Knowing the relationship between the air pollution and the hospital costs of stroke can help us predict the costs due to air pollution, provide grounds for the allocation of medical insurance funds, and provide better working arrangements for CDC. However, few studies have examined this connection. We used time series analysis with a generalized additive model to estimate the …

This paper will first go over some basic terms and concepts, then discuss what’s going on in the world around cannabis with a focus on the United States. I will then offer some policy options to consider if New York chooses to legalize recreational cannabis.

Is There Less Opioid Abuse In States Where Marijuana Has Been Decriminalized, Either For Medicinal Or Recreational Use? A Clin-Iq, Aaron M. Wendelboe, Richard Mathew, Tana Chongsuwat, Elizabeth Rainwater, Mark A. Wendelboe, Elizabeth Wickersham Md, Ann F. Chou

Journal of Patient-Centered Research and Reviews

Opioid use, abuse, and associated mortality have reached an epidemic level. In some states, cannabis is being used to treat chronic pain. To examine the hypothesis that medical marijuana legislation may reduce adverse opioid-related outcomes if patients substitute cannabis for opioids for pain management, we conducted a clinical inquiry (Clin-IQ). We searched Ovid MEDLINE, Ovid MEDLINE In-Process, and Embase for studies using the search terms marijuana, cannabis, legal, marijuana smoking, medical marijuana, opioid-related disorders, cannabis use, medical cannabis, legal aspect, and opiate addiction. We included population-based articles published from January 1, 2012, through December 5, 2018, that assessed the relationship …

Department of Urology Faculty Papers

OBJECTIVE: To provide the first comprehensive analysis of the Twitter-verse amongst academic urologists and programs in North America.

METHODS: Using national accreditation and individual program websites, all active urology residency programs (USA & Canada) and academic Urology faculty at these programs were identified. Demographic data for each program (AUA section, resident class size) and physician (title, fellowship training, Scopus H-index and citations) were documented. Twitter metrics (Twitter handle, date joined, # tweets, # followers, # following, likes) for programs and physicians were catalogued (data capture: March-April 2019). Descriptive analyses and temporal trends in Twitter utilization amongst programs and physician were …

Burdern Of Chronic Health Conditions And Healthcare Utilization Among Mobile Populations In Sub-Saharan Africa, Elizabeth M. Ortiz

Dissertations and Theses

Background: Much of public health research in sub-Saharan Africa on mobile occupations, such as truck drivers and sex workers, has focused on HIV risk. However, evidence is emerging to suggest that the HIV epidemic among these groups is coupled with a high prevalence of chronic health conditions (CHC), specifically hypertension, diabetes, and obesity. For people living with HIV, increased risk of CHC may also be linked to HIV-related chronic inflammatory cascade. In Africa, there has been little research on CHC risk factors or patterns of healthcare utilization among mobile populations. Therefore, the objectives of this study are to examine the …

The Upper East Side Vs Central Harlem: What Is Responsible For The Dermatology Disparities That Shaped These Communities?, Zakiya Cush, Jeffrey Weinberg

Annual SHSP Student Research and Scholarship Day

Very few studies have been done to understand why there is a paucity of dermatology practices in the Central Harlem (CH) community in Manhattan. This ecological and exploratory study will identify factors such as, geographical location, race, socioeconomic status, health care and medical education, as reasons why there is a disparity between the dermatology services in the CH community versus the Upper East Side (UES) of Manhattan. Thus, examining the differences in the neighborhoods as a mediator, it is hypothesized there is a need for increased dermatology practices to CH, as not catering to the clinical needs of a community …

Variations In 25-Hydroxyvitamin D In Countries From The Middle East And Europe: The Roles Of Uvb Exposure And Diet, William B. Grant, Hana M.A. Fakhoury, Spyridon N. Karras, Fatme Al Anouti, Harjit P. Bhattoa

All Works

© 2019 by the authors. Licensee MDPI, Basel, Switzerland. Serum 25-hydroxyvitamin D (25(OH)D) has been largely associated with latitude and sunshine exposure across several regions. According to previous results, 25(OH)D concentrations are, on average, relatively low in countries with abundant sunshine, including those of the Middle East and North Africa region, as well as lower-latitude Europe. The standard explanation for this phenomenon is that people wear concealing clothing because of cultural and religious practices and that high temperatures in summer limit direct sun exposure. However, the role of diet in the development of profound hypovitaminosis D has not been adequately …

Climate Change And Chagas Disease In The Americas: A Qualitative Systematic Review, Brittany N. Graves

Dissertations and Theses (Open Access)

While many studies have found associations between climate change and factors affecting Chagas disease transmission, the future impact of climate change on the global spread of Chagas disease remains debatable. A qualitative, systematic review was conducted to assess the impact of climate change on Chagas disease transmission in the Americas (Central America, South America, and North America). The literature search was performed in January 2019 using the keywords climate, Chagas, and “trypanosoma cruzi” and the electronic databases PubMed, Scopus, and Ovid. Searches retrieved records from 1982 through 2019. The initial electronic database search identified a total of 191 record documents …

Exploring Neighborhood Level Variation In Incidence And Secondary Transmission Of Seasonal Influenza, Melissa Freeland

Masters Theses

Influenza epidemics in the United States, are major causes of morbidity and mortality, and cause serious economic disruption on an annual basis. Evidence has begun to accumulate linking neighborhood-level socioeconomic disadvantage to higher rates of hospitalization and mortality related to influenza (Cordoba & Aiello, 2016; Jung, Lin, & Viswanath, 2013). Some studies suggest that this may be due to lower rates of vaccination, higher rates of comorbidities in socioeconomically disadvantaged communities (Cordoba & Aiello, 2016; Jung, Lin, & Viswanath, 2013; Ross & Mirowsky, 2001). However, few studies have evaluated the effects of neighborhood level socioeconomic disadvantage and structural features on …

Structural Racism And Odds For Infant Mortality Among Infants Born In The United States 2010, Roman Pabayo, Amy Ehntholt, Kara L. Davis, Sze Yan Liu, Peter Muening, Daniel Cook

Department of Public Health Scholarship and Creative Works

Abstract

OBJECTIVES:

While ecological studies indicate that high levels of structural racism within US states are associated with elevated infant mortality rates, studies using individual-level data are needed. To determine whether indicators of structural racism are associated with the individual odds for infant mortality among white and black infants in the US.

METHODS:

We used data on 2,163,096 white and 590,081 black infants from the 2010 US Cohort Linked Birth/Infant Death Data Files. Structural racism indicators were ratios of relative proportions of blacks to whites for these domains: electoral (registered to vote and voted; state legislature representation), employment (civilian labor …

Goats Distinguish Between Positive And Negative Emotion-Linked Vocalisations, Luigi Baciadonna, Elodie Briefer, Livio Favaro, A. G. Mcelligott

Bioacoustics Collection

Background: Evidence from humans suggests that the expression of emotions can regulate social interactions and promote coordination within a group. Despite its evolutionary importance, social communication of emotions in non-human animals is still not well understood. Here, we combine behavioural and physiological measures, to determine if animals can distinguish between vocalisations linked to different emotional valences (positive and negative). Using a playback paradigm, goats were habituated to listen to a conspecific call associated with positive or negative valence (habituation phase) and were subsequently exposed to a variant of the same call type (contact call) associated with the opposite valence (dishabituation …

Epilepsy Diagnosis And Management Of Children In Kenya: Review Of Current Literature, Pauline Samia, Jane Hassell, Jessica-Anne Hudson, Symon M. Kariuki, Charles R. Newton, Jo M. Wilmshurst

Paediatrics and Child Health, East Africa

Introduction: The growing impact of non-communicable diseases in low- to middle-income countries makes epilepsy a key research priority. We evaluated peer-reviewed published literature on childhood epilepsy specific to Kenya to identify knowledge gaps and inform future priorities.

Methodology: A literature search utilizing the terms “epilepsy” OR “seizure” as exploded subject headings AND “Kenya” was conducted. Relevant databases were searched, generating 908 articles. After initial screening to remove duplications, irrelevant articles, and publications older than 15 years, 154 papers remained for full-article review, which identified 35 publications containing relevant information. Data were extracted from these reports on epidemiology, etiology, clinical features, …

Evolutionary Dynamics Of Influenza Type B In The Presence Of Vaccination: An Ecological Study, Lindsey J. Fiedler

USF Tampa Graduate Theses and Dissertations

Understanding the evolutionary dynamics of influenza type B in human hosts is a public health concern as we strive to minimize the disease burden in seasonal epidemics. Vaccination is considered the best defense against contracting influenza, and everyone over the age of 6 months is advised to get vaccinated before each season. The effect that vaccine-acquired immunity has on the evolution of influenza B remains unclear. In the U.S., vaccine-uptake is irregular across the states, and the differing coverages present an opportunity to study how vaccination influences viral evolution. This thesis analyzes the evolutionary patterns of influenza B in the …

Nrxn1 Deletion And Exposure To Methylmercury Increase Astrocyte Differentiation By Different Notch-Dependent Transcriptional Mechanisms, Marilena Raciti, Salma Jahan, Stefan Spulber, Giulia Gaudenzi, Zahra Khalajzeyqami, Mirko Conti, Britt-Marie Anderlid, Anna Falk, Ola Hermans, Sandra Ceccatelli

Centre for Regenerative Medicine & Stem Cell Research

Controversial evidence points to a possible involvement of methylmercury (MeHg) in the etiopathogenesis of autism spectrum disorders (ASD). In the present study, we used human neuroepithelial stem cells from healthy donors and from an autistic patient bearing a bi-allelic deletion in the gene encoding for NRXN1 to evaluate whether MeHg would induce cellular changes comparable to those seen in cells derived from the ASD patient. In healthy cells, a subcytotoxic concentration of MeHg enhanced astroglial differentiation similarly to what observed in the diseased cells (N1), as shown by the number of GFAP positive cells and immunofluorescence signal intensity. In both …

Alcohol Sale Status And Homicide Victimization In Kentucky, 2005-2012: Is There A Spatial Association?, Hanan Abdulghafoor Khaleel, Sabrina Brown, Steven T. Fleming, W. Jay Christian

Epidemiology and Environmental Health Faculty Publications

To date, the association between the alcohol sale status of decedents’ residence and alcohol-related homicide victimization have not been studied as far as we know. The current study aims to: i) determine whether homicide victims who were residents of wet counties had higher odds of testing positive for alcohol than their counterparts in moist or dry counties after adjusting for confounders; ii) determine whether homicides and alcohol-related homicides tend to cluster spatially; iii) determine whether the aforementioned associations exist only in highly-populated counties. A multilevel logistic regression analysis was used to analyze the data on homicide victims in the Kentucky …

American And British Speech Differences In Low Socioeconomic Status Homes, Jennifer Markfeld

Senior Honors Projects, 2010-2019

Background: Infants living in low socioeconomic status (SES) homes display lower developmental functioning by 12 months than mid- and high-SES infants, and speak fewer words on average as they grow older. Maternal speech is especially important for language development and has been found to be the largest predictor of SES-related differences in children’s vocabulary. Although there are documented differences between British and American infant language development, for example American infant lexicons are typically larger than age matched British infants, there is little research looking at caregiver speech across these countries in low SES groups.

Method: This retrospective study compared 10 …

Community-Based Healthcare | Interlace Of Biophilic Design In Outpatient Facilities, Joshua Robinson

Bachelor of Architecture Theses - 5th Year

This thesis questions how architects can redesign typical healthcare typology in response to the medical and sociological needs of the community while integrating the measures of wellness and biophilic design. By redefining architectural programs within a wellness clinic, this can allow the facility to prioritize the communities needs through non-medical determinants. The research will look at both the social and medical needs of a community, along with the Seven Standards of Wellness as defined by the Well Building Standard and The Fourteen Patterns of Biophilic Design as defined by the Terrapin Bright Green, to develop a connection between the facility …

Spatial Distribution Of Tuberculosis And Its Association With Meteorological Factors In Mainland China, Yingjie Zhang, Mengyang Liu, Samuel S. Wu, Hui Jiang, Junjie Zhang, Songwang Wang, Wei Ma, Qihuan Li, Yuan Ma, Yue Liu, Wei Feng, Endawoke Amsalu, Xia Li, Wei Wang, Weimin Li, Xiuhua Guo

Research outputs 2014 to 2021

BACKGROUND: The incidence of tuberculosis (TB) remains high worldwide. Current strategies will not eradicate TB by 2035; instead, by 2182 is more likely. Therefore, it is urgent that new risk factors be identified.

METHODS: An ecological study was conducted in 340 prefectures in China from 2005 to 2015. The spatial distribution of TB incidence was shown by clustering and hotspot analysis. The relationship between the distribution patterns and six meteorological factors was evaluated by the geographically weighted regression (GWR) model.

RESULTS: During the 11 years of the study period, TB incidence was persistently low in the east and high in …

Intersex Wildlife As Sentinels For Human Health And Endocrine Disruption Near Superfund Sites: A Systematic Review, Olivia Anderson, Melissa Perry

GW Research Days 2016 - 2020

Fish and wildlife are often used as sentinels for human health. This systematic review examines one aspect of wildlife health, intersex (both ovarian and testicular tissue) animals and their prevalence or severity near Superfund sites (EPA designated toxic waste sites). The body of evidence demonstrates some evidence of this indicator and more research is needed, specifically a meta-analysis that is outside the scope of this study.

Direct Lung Sampling Indicates That Established Pathogens Dominate Early Infections In Children With Cystic Fibrosis., Peter Jorth, Zarmina Ehsan Md, Amir Rezayat, Ellen Caldwell, Christopher Pope, John J. Brewington, Christopher H. Goss, Dan Benscoter, John P. Clancy, Pradeep K. Singh

Manuscripts, Articles, Book Chapters and Other Papers

Culture and sequencing have produced divergent hypotheses about cystic fibrosis (CF) lung infections. Culturing suggests that CF lungs are uninfected before colonization by a limited group of CF pathogens. Sequencing suggests diverse communities of mostly oral bacteria inhabit lungs early on and diversity decreases as disease progresses. We studied the lung microbiota of CF children using bronchoscopy and sequencing, with measures to reduce contamination. We found no evidence for oral bacterial communities in lung lavages that lacked CF pathogens. Lavage microbial diversity varied widely, but decreases in diversity appeared to be driven by increased CF pathogen abundance, which reduced the …

Rediscovering The Axolotl As A Model For Thyroid Hormone Dependent Development, Anne Crowner, Shivam Khatri, Dana Blichmann, S. Randal Voss

Neuroscience Faculty Publications

The Mexican axolotl (Ambystoma mexicanum) is an important model organism in biomedical research. Much current attention is focused on the axolotl's amazing ability to regenerate tissues and whole organs after injury. However, not forgotten is the axolotl's equally amazing ability to thwart aspects of tissue maturation and retain juvenile morphology into the adult phase of life. Unlike close tiger salamander relatives that undergo a thyroid hormone regulated metamorphosis, the axolotl does not typically undergo a metamorphosis. Instead, the axolotl exhibits a paedomorphic mode of development that enables a completely aquatic life cycle. The evolution of paedomorphosis allowed axolotls …

Controlled Ecological Evaluation Of An Implemented Exercise-Training Programme To Prevent Lower Limb Injuries In Sport: Population-Level Trends In Hospital-Treated Injuries, Caroline F. Finch, Shannon E. Gray, Muhammad Akram, Alex Donaldson, David G. Lloyd, Jill L. Cook

Research outputs 2014 to 2021

OBJECTIVE: Exercise-training programmes have reduced lower limb injuries in trials, but their population-level effectiveness has not been reported in implementation trials. This study aimed to demonstrate that routinely collected hospital data can be used to evaluate population-level programme effectiveness.

METHOD: A controlled ecological design was used to evaluate the effect of FootyFirst, an exercise-training programme, on the number of hospital-treated lower limb injuries sustained by males aged 16-50 years while participating in community-level Australian Football. FootyFirst was implemented with 'support' (FootyFirst+S) or 'without support' (FootyFirst+NS) in different geographic regions of Victoria, Australia: 22 clubs in region 1: FootyFirst+S in 2012/2013; …

Respiratory Infections And Risk For Development Of Narcolepsy: Analysis Of The Truven Health Marketscan Database (2008 To 2010) With Additional Assessment Of Incidence And Prevalence, Darren Scheer

USF Tampa Graduate Theses and Dissertations

Background and Significance: Narcolepsy is a chronic neurological disorder. These patients experience various psychiatric and physical comorbid diseases and mortality at an increased rate compared to the general population. Additionally, patients with narcolepsy experience approximately a doubling of various annual healthcare related facility visits, transactions, and costs comparatively. Narcolepsy with cataplexy is generally believed to be more prevalent than narcolepsy without cataplexy. However, incidence and prevalence estimates of narcolepsy (with or without cataplexy) vary widely with few large epidemiological studies conducted worldwide and none in the U.S evaluating these proportions in both children and adults utilizing a large health care …

Persistent Appalachian Health Disparities: An Integrative Literature Review

Richard Trosper

Research Sponsor: Elizabeth P Anderson RN, PhD

Background: The area surrounding the Appalachian Mountains is referred to as Appalachia. There are 420 counties in 13 states which are considered to be part of the Appalachian region (Shapiro, 2001). Despite the progress made by the Kennedy and Johnson administrations, health in Appalachia still falls far behind that of other parts of America (Widner, 1990). This disparity has been termed and utilized in research in the realm of limited health care access, different diseases, and health related problems confused with the complexity …

Use Of Plumage And Gular Pouch Color To Evaluate Condition Of Oil Spill Rehabilitated California Brown Pelicans (Pelecanus Occidentalis Californicus) Post-Release, Deborah L. Jaques, Kyra L. Mills, Barton G. Selby, Richard R. Veit, Michael H. Ziccardi

Publications and Research

Sublethal effects of oil spills may dampen seabird rehabilitation success due to lingering negative impacts of contamination and stress on reproduction and long-term survival. These effects can be difficult to measure while birds are in care as well as once birds are released. Expression of sexually selected traits that are sensitive to condition can provide information on physiological status of birds. We evaluated plumage molt and gular pouch skin color of California brown pelicans (Pelecanus occidentalis californicus) following oil contamination and rehabilitation to test for differences between previously oiled and rehabilitated (post-spill) and presumably uncontaminated pelicans. Post-spill pelicans released with …

A State-Level Study Of Opioid Use Disorder Treatment Access And Neonatal Abstinence Syndrome, Elizabeth R. Wolf, Sebastian T. Tong, Roy T. Sabo, Steven H. Woolf, Kassie Abbinanti, James Pecsok, Alex H. Krist

Pediatrics Publications

Background Adult opioid use and neonatal abstinence syndrome (NAS) are growing public health problems in the United States (U.S.). Our objective was to determine how opioid use disorder treatment access impacts the relationship between adult opioid use and NAS.

Methods We conducted a cross-sectional state-level ecologic study using 36 states with available Healthcare Cost and Utilization Project State Inpatient Databases in 2014. Opioid use disorder treatment access was determined by the: 1) proportion of people needing but not receiving substance use treatment, 2) density of buprenorphine-waivered physicians, and 3) proportion of individuals in outpatient treatment programs (OTPs). The incidence of …

The Association Between Urinary Genistein Levels And Mortality Among Adults In The United States, Carolyn Marcelo, Melissa Warwick, Catherine Marcelo, Rehan Qayyum

Internal Medicine Publications

Background
Current research on the relationship between phytoestrogens and mortality has been inconclusive. We explored the relationship between genistein, a phytoestrogen, and mortality in a large cohort representative of the United States population.


Methods: Data were analyzed from the National Health and Nutrition Examination Survey (NHANES) from 1999–2010. Normalized urinary genistein (nUG) was analyzed as a log-transformed continuous variable and in quartiles. Mortality data were obtained from the National Death Index and matched to the NHANES participants. Survival analyses were conducted using the Kaplan-Meier analysis. Cox proportional hazard models were constructed for all-cause and cause-specific mortality without and with …

Increased Dementia Mortality In West Virginia Counties With Mountaintop Removal Mining?, A. K. Salm, Michael J. Benson

Faculty & Staff Scholarship

(MTM), a practice that has been ongoing in some counties of West Virginia (WV) USA since the 1970s. PM inhalation has been linked to central nervous system pathophysiology, including cognitive decline and dementia. Here we compared county dementia mortality statistics in MTM vs. non-MTM WV counties over a period spanning 2001–2015. We found significantly elevated age-adjusted vascular or unspecified dementia mortality/100,000 population in WV MTM counties where, after adjusting for socioeconomic variables, dementia mortality was 15.60 (±3.14 Standard Error of the Mean (S.E.M.)) times higher than that of non-MTM counties. Further analyses with satellite imaging data revealed a highly significant …
