School of Mathematical and Statistical Sciences Faculty Publications and Presentations

Background: Anticipating an initial shortage of vaccines for COVID-19, the Centers for Disease Control (CDC) in the United States developed priority vaccine allocations for specific demographic groups in the population. This study evaluates the performance of the CDC vaccine allocation strategy with respect to multiple potentially competing vaccination goals (minimizing mortality, cases, infections, and years of life lost (YLL)), under the same framework as the CDC allocation: four priority vaccination groups and population demographics stratified by age, comorbidities, occupation and living condition (congested or non-congested).

Methods and findings: We developed a compartmental disease model that incorporates key elements of the …

Reproductive Health Policy Saga: Restrictive Abortion Laws In Low- And Middle-Income Countries (Lmics), Unnecessary Cause Of Maternal Mortality, Ngo Valery Ngoa, Ngambouk Vitalis Pemuntaa, Basil N. Nduma, Fokunang Estella Tembe, Mbong Sidonnie Eyambe, Keziah Ezra, Henry Che Ngwa, Emmanuel Ombugadu Sabo

Health & Biomedical Sciences Faculty Publications and Presentations

Abortion is a common but controversial phenomenon globally. The discourse on the legality of abortion remains intricate, leaving a substantial number of women restricted from accessing safe abortion. There are evidence of an association between restrictive abortion laws, unsafe abortions, and maternal mortality in low-and middle-income countries (LMICs). We explore how restrictive abortion laws violate women’s right to health and bodily integrity. We used Carol Bacchi’s policy framework to analyze how restrictive abortion laws have been discursively framed (problematization); the assumptions that underpinned the representation; the consequences of the representation; what was left unproblematic; how the representation could be questioned, …

Mitigating The Externality Of Diseases Of Poverty Through Health Aid, Kamal Jnawali, Michael G. Tyshenko, Tamer Oraby

School of Mathematical and Statistical Sciences Faculty Publications and Presentations

Externality exists in healthcare when an individual benefits from others being healthy as it reduces the probability of getting sick from illness. Healthy workers are considered to be the more productive labourers leading to a country’s positive economic growth over time. Several research studies have modelled disease transmission and its economic impact on a single country in isolation. We developed a two-country diseaseeconomy model that explores disease transmission and crossborder infection of disease for its impacts. The model includes aspects of a worsening and rapid transmission of disease juxtaposed by positive impacts to the economy from tourism. We found that …

MEDI 9331 Scholarly Activities Clinical Years

Cancers of the oral cavity (OC) and oropharynx (OP) account for 3% of cancers diagnosed in the United States each year. A primary cause of death among the Hispanic population in the United States is cancer, accounting for 20% of annual mortality. The Rio Grande Valley (RGV) is a medically-underserved area of South Texas with a large Hispanic population facing health disparities. In this study, we examine the incidence and mortality of OC and OP cancer in the RGV. CDC population-level incidence and mortality rate per 100,000 of OC/OP cancer among patients in the RGV counties of Hidalgo and Cameron …

Implications Of Helminth Immunomodulation On Covid-19 Co-Infections, Nathalie Chacon, Leonor Chacin-Bonilla, Italo M. Cesar

School of Medicine Publications and Presentations

Coronavirus disease 2019 (COVID-19) and helminths infections can be in a synergistic epidemic in developing and suburban areas of industrialized countries. The coinfected hosts will derive a parasite-specific Th2 innate and adaptive immune response with CD4+ T cells, eosinophils, interleukin-4, interleukin-5, and interleukin-10. In the early stages of severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) infection, virus-specific Th1 cytotoxic CD8+ T cell, interleukin-6, interferon-γ, and interleukin-27 by lung are keys in controlling viral replication in the lung epithelial cells and limiting the pathology to other organs, like the intestine. CD4+ and CD8+ T cells are associated with protective immunity …

Inoculation Of Juvenile Monodelphis Domestica With Zika Virus Using Various Routes Of Infection, Juan Garcia Jr.

Theses and Dissertations

Monodelphis domestica is a small marsupial from South America that has been previously been used in human metabolism research. However, their suitability as models for Zika virus (ZIKV) research, is currently unknown. Preliminary studies have shown M. domestica susceptible to ZIKV through the intracerebral route. We utilized immunohistochemistry, and analyzation of serological responses to show that juvenile Monodelphis domestica can be infected with ZIKV by using various routes of infection that include subcutaneous, intraperitoneal, and intramuscular. ELISAs performed on sera confirmed that juveniles injected with ZIKV by all three routes generated anti-ZIKV antibodies. Additionally, ZIKV nonstructural protein 1 was detected …

Sars-Cov-2: Potencial Transmisión Feco-Oral E Implicaciones En La Propagación Y Gravedad Del Covid-19 En Venezuela. Mini-Revisión. [Sars-Cov-2: Potential Feco-Oral Transmission And Implications On The Spread And Severity Of Covid-19 In Venezuela. Mini-Review.], Leonor Chacin-Bonilla, Nathalie Chacon

School of Medicine Publications and Presentations

The recognized human-to-human transmission of SARS-CoV-2 is through respiratory droplets and contact with contaminated surfaces. However, the high transmissibility of the virus and the pattern of symptoms of COVID-19 suggest the likelihood of other forms of spread. Increasing evidence suggests that SARS‐CoV‐2 could be transmitted by the feco‐oral route. SARS-CoV-2 is known to infect gastrointestinal epithelial cells and a significant number of infected people have gastrointestinal symptoms. Viable viruses, viral RNA, and prolonged shedding of viral RNA have been detected in the feces of COVID-19 patients. The virus has been found in sewage and surface waters of several countries. The …

School of Mathematical and Statistical Sciences Faculty Publications and Presentations

The application, timing, and duration of lockdown strategies during a pandemic remain poorly quantified with regards to expected public health outcomes. Previous projection models have reached conflicting conclusions about the effect of complete lockdowns on COVID-19 outcomes. We developed a stochastic continuous-time Markov chain (CTMC) model with eight states including the environment (SEAMHQRD-V), and derived a formula for the basic reproduction number, R0, for that model. Applying the R 0 formula as a function in previously-published social contact matrices from 152 countries, we produced the distribution and four categories of possible R 0 for the 152 countries and chose one …

Cervical Cancer, Human Papillomavirus (Hpv), And Hpv Vaccination: Exploring Gendered Perspectives, Knowledge, Attitudes, And Cultural Taboos Among Mexican American Adults, Daisy Y. Morales-Campos, S. A. Snipes, Edna K. Villarreal, L. C. Crocker, A. Guerrero, M. E. Fernandez

Physician Assistant Studies Faculty Publications and Presentations

Background: Gendered perspectives may be particularly important in shaping norms and values around HPV and HPV vaccination, as previous research suggests that sexuality taboos (e.g. promiscuity) may contribute to low perceived risk among adolescent and young adult Hispanic females. However, research to date focuses primarily on Hispanic mothers, adolescent females, and women of HPV vaccine-eligible age. Hispanic father's perspectives are relatively unknown despite father's important role in shaping norms for their female children.

Objective: To close this gap, this study examines gendered perspectives in knowledge, beliefs, and attitudes about HPV and HPV vaccination from Hispanic parents (mothers and fathers), women …

Strategically Rational Risk Taking By Age In Covid-19, And The Heterogeneous Agent Behavioral Sir Model, Siamak Javadi, Elena Quercioli, Lones Smith

Economics and Finance Faculty Publications and Presentations

Given the dramatic age variation in COVID death rates, we create a heterogeneous agent version of the Behavioral SIR contagion model of Engle et al. (2020). The Bayes Nash equilibrium of our infection avoidance game yields a simple new log-linear relationship between the case fatality rate (CFR) and COVID incidence: Everyone knows that everyone optimizes vigilance both for the prevalence and their CFR. We explain 2020 CDC incidence data for the USA north-east in terms of the CFR to age-specific COVID death data for Massachusetts. Our model is statistically significant: A 10% higher CFR reduces incidence by about 1%.

Physics and Astronomy Faculty Publications and Presentations

The imposition and lifting of non-pharmaceutical interventions (NPIs) to avert the COVID19 pandemic have gained popularity worldwide and will continue to be enforced until herd immunity is achieved. We developed a linear regression model to ascertain the nexus between the time-varying reproduction number averaged over a time window of six days (Rts) and seven NPIs: contact tracing, quarantine efforts, social distancing and health checks, hand hygiene, wearing of facemasks, lockdown and isolation, and health-related supports. Our analysis suggests that the second wave that emerged in Sri Lanka in early October 2020 continued despite numerous NPIs. The model indicates that the …
