Obsessive-compulsive disorder is an impairing psychiatric condition affecting 1-2% of adults and youth. Cognitive-behavioral therapy with exposure and response prevention (CBT) is an efficacious intervention but requires specialty training and access is often limited. While certain factors are associated with treatment access, one key barrier that has not been explored is the geographic availability of OCD treatment providers. Using integrated geographically-referenced data, we examined the geographic distribution of OCD CBT specialty providers across the state of Texas, with particular attention to the relationship to neighborhood socioeconomic disadvantage, insurance status, and rural versus urban status. We found that specialist providers are …

Analisis Survival: Hubungan Konversi Sputum Dengan Keberhasilan Pengobatan Pasien Tuberkulosis Resistan Obat Di Indonesia, Shena Masyita Deviernur, Nurhayati Adnan

Jurnal Epidemiologi Kesehatan Indonesia

Angka keberhasilan pengobatan Tuberkulosis Resistan Obat (TB RO) di Indonesia masih rendah. Konversi sputum dapat menjadi monitoring awal untuk memantau keberhasilan pengobatan. Penelitian ini bertujuan untuk melihat hubungan antara konversi sputum <3 bulan dengan keberhasilan pengobatan. Penelitian ini menggunakan desain studi kohort retrospektif dengan data yang bersumber dari sistem informasi tuberkulosis Kementerian Kesehatan RI. Populasi pada penelitian ini adalah pasien TB RO yang memulai pengobatan tahun 2020-2021 di Indonesia dengan jumlah sampel sebanyak 8.025 kasus dan participation rate sebesar 88,6%. Kurva Kaplan Meier dengan uji log-rank dibuat untuk analisis deskriptif, sedangkan analisis regresi Cox digunakan untuk melihat hubungan antara konversi sputum dengan keberhasilan pengobatan. Hasil analisis menunjukkan bahwa 45,9% pasien konversi sputum < 3 bulan pengobatan dengan 74,6% memiliki keberhasilan pengobatan. Secara keseluruhan median time untuk keberhasilan pengobatan berdasarkan konversi sputum < 3 bulan adalah bulan ke-18. Hasil analisis multivariat menunjukkan konversi sputum < 3 bulan 1,25 (95% CI 1,18-1,34) lebih tinggi peluangnya untuk mencapai keberhasilan pengobatan dibandingkan pasien yang tidak konversi < 3 bulan setelah dikontrol oleh status HIV dan paduan pengobatan. Berdasarkan hasil penelitian ini dapat disimpulkan bahwa monitoring konversi sputum dapat menjadi cara untuk melakukan monitoring keberhasilan pengobatan sedini mungkin. Konversi sputum merupakan standar yang dilakukan untuk pemantauan pengobatan pasien TB RO. Namun jumlah laboratorium yang dapat melakukan pemeriksaan untuk konversi pada pasien TB RO masih terbatas. Perlu adanya perluasan layanan dan peningkatan mutu layanan untuk melakukan pemeriksaan konversi sputum pada pasien TB RO.

(R2032) Modeling The Effect Of Sanitation Effort On The Spread Of Carrier-Dependent Infectious Diseases Due To Environmental Degradation, Ram Naresh, Sandhya Rani Verma, J. B. Shukla, Manju Agarwal

Applications and Applied Mathematics: An International Journal (AAM)

In this present study, an SIS model is proposed and analyzed to study the effect of sanitation effort in controlling the spread of carrier-dependent infectious disease in a human habitat due to environmental degradation. The dynamics of the model consist of six dependent variables, the susceptible population density, infective population density, carrier population density, cumulative density of environmental degradation and the density of sanitation effort applied on carrier population and degraded environment. In the modeling process, the carrier population density and sanitation effort are modeled logistically and the degradation of the environment is assumed to be directly proportional to the …

Through the experiences gained by accelerating new vaccines for both Ebola virus infection and COVID-19 in a public health emergency, vaccine development has benefited from a 'multiple shots on goal' approach to new vaccine targets. This approach embraces simultaneous development of candidates with differing technologies, including, when feasible, vesicular stomatitis virus or adenovirus vectors, messenger RNA (mRNA), whole inactivated virus, nanoparticle and recombinant protein technologies, which led to multiple effective COVID-19 vaccines. The challenge of COVID-19 vaccine inequity, as COVID-19 spread globally, created a situation where cutting-edge mRNA technologies were preferentially supplied by multinational pharmaceutical companies to high-income countries while …

The kidneys operate at the interface of plasma and urine by clearing molecular waste products while retaining valuable solutes. Genetic studies of paired plasma and urine metabolomes may identify underlying processes. We conducted genome-wide studies of 1,916 plasma and urine metabolites and detected 1,299 significant associations. Associations with 40% of implicated metabolites would have been missed by studying plasma alone. We detected urine-specific findings that provide information about metabolite reabsorption in the kidney, such as aquaporin (AQP)-7-mediated glycerol transport, and different metabolomic footprints of kidney-expressed proteins in plasma and urine that are consistent with their localization and function, including the …

Advantages Of Whole Genome Sequencing In Mitigating The Helicobacter Pylori Antimicrobial Resistance Problem, Kartika Afrida Fauzia, Ricky Indra Alfaray, Yoshio Yamaoka

Faculty, Staff and Students Publications

Helicobacter pylori antimicrobial resistance is a critical public health issue. Typically, antimicrobial resistance epidemiology reports include only the antimicrobial susceptibility test results for H. pylori. However, this phenotypic approach is less capable of answering queries related to resistance mechanisms and specific mutations found in particular global regions. Whole genome sequencing can help address these two questions while still offering quality control and is routinely validated against AST standards. A comprehensive understanding of the mechanisms of resistance should improve H. pylori eradication efforts and prevent gastric cancer.

Vaccines In The 20th Century, Samantha Valakos May 2023

Vaccines In The 20th Century, Samantha Valakos

Senior Honors Projects

In 1796 Edward Jenner marked a turning point in epidemiology after testing a theory and developing the first vaccination known to mankind: smallpox. Since his work, many scientists have discovered that virulent strains of a virus can be attenuated in humans, consequently aiding in the creation of many different vaccines. Nowadays, one of the most common vaccines for humans to receive is the influenza vaccine. The influenza vaccine is very effective in prevention of getting the virus, as well as reducing the risk of flu-like symptoms. However, each year many individuals continue to choose not to get the flu vaccine …

The University of Louisville Journal of Respiratory Infections

Background

Even though the proportional burden of COPD among never-smokers is significant in both developing and developed nations, accounting for around 30% of all COPD in the community, there is little awareness of the prevalence of COPD in this population. Understanding the molecular processes that underlie COPD in nonsmokers is essential.

Methods

Dataset (GSE146560) was acquired from the Gene Expression Omnibus (GEO). The limma and clusterProfiler software tools were used to identify differentially expressed genes (DEGs) and conduct a functional enrichment analysis respectively.

Results

In all, 10,583 DEGs were found, of which 1,065 were up-regulated and 9,518 were down-regulated. The …

Emerging Tick-Borne Diseases In Northeast Tennessee, Jacob Schultz

Electronic Theses and Dissertations

Tick populations have been immigrating into northeast Tennessee from east Tennessee, Kentucky, Virginia, and North Carolina. Counties in states bordering northeast Tennessee harbor tick species associated with human illness. Human diseases transmitted by ticks include ehrlichiosis, spotted fever rickettsial group diseases, tularemia, anaplasmosis, babesiosis, Lyme disease, alpha-gal syndrome, Heartland virus, Powassan virus, and southern tick-associated rash illness (STARI). These diseases cause morbidity and mortality in human populations and may pose a high risk to individuals, wildlife, and livestock. The Cherokee National Forest covering the east Tennessee border provides a permissible environment for ticks to immigrate and thrive. Residents of northeast …

Research outputs 2022 to 2026

The adsorption behaviour of micro-organisms during the initial attachment stage of biofilm formation affects subsequent stages. The available area for attachment and the chemophysical properties of a surface affect microbial attachment performance. This study focused on the initial attachment behaviour of Klebsiella aerogenes on monazite by measuring the ratio of planktonic against sessile subpopulations (P:S ratio), and the potential role of extracellular DNA (eDNA). eDNA production, effects of physicochemical properties of the surface, particle size, total available area for attachment, and the initial inoculation size on the attachment behaviour were tested. K. aerogenes attached to monazite immediately after exposure to …


Communicating Health: Misinformation And Mistrust In The Age Of Coronavirus, Chris Anstead Apr 2023

Communicating Health: Misinformation And Mistrust In The Age Of Coronavirus, Chris Anstead

Undergraduate Theses

With one of the most advanced medical systems in the world, the Untied States still experienced an exceedingly high COVID-19 death rate per capita. Because biomedical therapies for COVID-19 were available, the focus of this review is on the social aspects of the COVID-19 response. By observing how Americans reacted to vaccination, masking, and social distancing guidelines, as well as how those guidelines were communicated to the general population from the public and private sectors, this thesis argues that the social and political aspects of the COVID-19 pandemic played a significant role in the outcome of the pandemic response. Additionally, …

Cellular metabolic dysregulation is a consequence of SARS-CoV-2 infection that is a key determinant of disease severity. However, how metabolic perturbations influence immunological function during COVID-19 remains unclear. Here, using a combination of high-dimensional flow cytometry, cutting-edge single-cell metabolomics, and re-analysis of single-cell transcriptomic data, we demonstrate a global hypoxia-linked metabolic switch from fatty acid oxidation and mitochondrial respiration towards anaerobic, glucose-dependent metabolism in CD8+Tc, NKT, and epithelial cells. Consequently, we found that a strong dysregulation in immunometabolism was tied to increased cellular exhaustion, attenuated effector function, and impaired memory differentiation. Pharmacological inhibition of mitophagy with mdivi-1 reduced excess glucose …

A Cross-Sectional Analysis Of Infectious Causes Of Congenital Morbidity And Mortality In Central America: Torch, El Salvador, Mary Katherine Lynn

Theses and Dissertations

The primary goal of this dissertation was to understand the prevalence of the most regionally salient TORCH pathogens among a group of perinatal women from a highly vulnerable region of El Salvador at the time of parturition. TORCH pathogens, that cause TORCH congenital syndromes, are classically defined as Toxoplasma gondii, other infectious causes of concern (Zika virus, malaria, human immunodeficiency virus, etc), Rubella virus, Cytomegalovirus(CMV), and Herpes Simplex Viruses. These infections can be passed from mother to fetus through the placenta or other perinatal routes and cause severe maternal and neonatal morbidity and mortality. This dissertation sought to understand perinatal …


Prevalence Of Sars-Cov-2 Antibodies In Liberty University Student Population, Emily Bonus Apr 2023

Prevalence Of Sars-Cov-2 Antibodies In Liberty University Student Population, Emily Bonus

Senior Honors Theses

In 2020, the virus SARS-CoV-2 gained attention as it spread around the world. Its antibodies are poorly understood, and little research focuses on those with few COVID-19 complications yet large numbers of close contacts: university students. This longitudinal study recorded SARS-CoV-2 antibody presence in 107 undergraduate Liberty University students twice during early 2021. After extensive data cleaning and the application of various statistical tests and ANOVAs, the data seems to show that in the case of COVID-19 infections, SARS-CoV-2 IgM antibodies are immediately produced, and then IgG antibodies follow later. However, the COVID-19 vaccine causes the production of both IgM …

Disease Risk Of Reintroducing Primates Confiscated From The Illegal Wildlife Trade, Ana Patricia Mendoza Becerra Mar 2023

Disease Risk Of Reintroducing Primates Confiscated From The Illegal Wildlife Trade, Ana Patricia Mendoza Becerra

Dissertations

Zoonotic infections are easily shared between human and other primates, and thus primate trafficking poses a high risk of introducing zoonotic pathogens into urban environments as well as spreading human-associated diseases into natural environments when infected primates are released. The magnitude of these risks has not been thoroughly studied in the context of primate trafficking and rehabilitation of Neotropical primates. In this dissertation, I address some knowledge gaps in disease risk analysis of reintroducing trafficked primates. In chapter 1, I describe the dynamics, diversity, and composition of live wildlife trafficking in urban markets in Peru. I found these markets are …
