School of Medicine Publications and Presentations
The pandemic of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) had overwhelmed the healthcare system worldwide with multiple ethical dilemmas. Several tools have been used to assess risk factors in these patients. One of them, the Clinical Frailty scale, has shown good correlation between the patient functional status and hospital stay with overall mortality. We present a case were the Clinical Frailty Scale was used to assess patient management and goals of care.

Hepatocellular carcinoma (HCC) is a primary malignant liver tumor that commonly occurs as a progression of chronic liver inflammation due to long-standing viral hepatitis infection, toxins, metabolic conditions, and congenital disorders. In 2018, HCC was the 4th leading cause of cancer-related deaths worldwide, accounting for approximately 780,000 deaths in total.
HCC’s prognosis is directly correlated with early detection. Unfortunately, HCC has an asymptomatic pattern of growth in the early stages of the disease which makes early detection challenging. When HCC progresses to advanced stages, it leaves clinicians with limited therapeutic and curative options, leading to high rates of morbidity and …

One of the biggest challenges during the coronavirus disease 2019 (COVID-19) pandemic continues to be the detection of asymptomatic and presymptomatic persons infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Persons infected with SARS-CoV-2 who do not have symptoms of COVID-19 may transmit the virus to others and may have subclinical lung abnormalities. Some hospitals use SARSCoV-2 antigen tests for pre-admission screening testing because they are relatively inexpensive, have a rapid turnaround time, and can be performed at the point of care; however, antigen tests are generally less sensitive than nucleic acid amplification tests with reverse transcription polymerase chain …

Aim
Acanthosis nigricans (AN) is a strong correlate of obesity and is considered a marker of insulin resistance (IR). AN is associated with various other cardiometabolic risk factors (CMRFs). However, the direct causal relationship of IR with AN in obesity has been debated. Therefore, we aimed to examine the complex causal relationships among the troika of AN, obesity, and IR in Mexican Americans (MAs).
Methods
We used data from 670 non-diabetic MA children, aged 6–17 years (49% girls). AN (prevalence 33%) severity scores (range 0–5) were used as a quasi-quantitative trait (AN-q) for analysis. We used the program SOLAR for …
Permutation Inference For Canonical Correlation Analysis, Anderson M. Winkler, Olivier Renaud, Stephen M. Smith, Thomas E. Nichols
Permutation Inference For Canonical Correlation Analysis, Anderson M. Winkler, Olivier Renaud, Stephen M. Smith, Thomas E. Nichols
School of Medicine Publications and Presentations
Canonical correlation analysis (CCA) has become a key tool for population neuroimaging, allowing investigation of associations between many imaging and non-imaging measurements. As age, sex and other variables are often a source of variability not of direct interest, previous work has used CCA on residuals from a model that removes these effects, then proceeded directly to permutation inference. We show that a simple permutation test, as typically used to identify significant modes of shared variation on such data adjusted for nuisance variables, produces inflated error rates. The reason is that residualisation introduces dependencies among the observations that violate the exchangeability …

Age is the dominant risk factor for most chronic human diseases, but the mechanisms through which ageing confers this risk are largely unknown1. The age-related acquisition of somatic mutations that lead to clonal expansion in regenerating haematopoietic stem cell populations has recently been associated with both haematological cancer2,3,4 and coronary heart disease5—this phenomenon is termed clonal haematopoiesis of indeterminate potential (CHIP)6. Simultaneous analyses of germline and somatic whole-genome sequences provide the opportunity to identify root causes of CHIP. Here we analyse high-coverage whole-genome sequences from 97,691 participants of diverse …

MEDI 9331 Scholarly Activities Clinical Years
Background
On March 17, 2020, the American Association of Medical Colleges issued a statement which “strongly supports medical schools pausing all student clinical rotations, effective immediately, until at least March 31.” The University of Texas Rio Grande Valley School of Medicine immediately withdrew third- and fourth-year students from clinical rotation sites, and developed alternative, online-based clerkship curricula to complete for the remainder of the academic year. The COVID-19 pandemic has brought about many challenges to Undergraduate Medical Education, and has deprived upper-level students of foundational, in-person, clinical experiences. The UTRGV School of Medicine Department of Neurology is among the first …

Variation and clade shifts in dengue virus (DENV) genotypes are responsible for numerous dengue fever outbreaks throughout Latin America in the past decade. Molecular analyses of dengue serotypes have revealed extensive genetic diversification and the emergence of new genotypes in Brazil (DENV-4 genotype I) and elsewhere in tropical and subtropical America. The goal of the present study is to assess the extent to which the adventitious introduction of DENV genotypes and their increasing genetic diversity affects dengue epidemiology in Mexico. A nuanced sequence inspection and phylogenetic analysis of the C-prM nucleotide region of DENV was performed for specimens collecting in …

Cancer cells exhibit distinct energy metabolic pathways due to multiple oncogenic events. In normoxia condition, the anaerobic glycolysis (Warburg effect) is highly observed in head and neck squamous cell carcinoma (HNSCC). HNSCC is associated with smoking, chewing tobacco, consumption of alcohol or Human Papillomavirus (HPV) infection primarily HPV16. In recent years, the correlation of HPV with HNSCC has significantly expanded. Despite the recent advancement in therapeutic approaches, the rate of HPV infected HNSCC has significantly increased in the last few years, specifically, in lower middle-income countries. The oncoproteins of High-risk Human Papillomavirus (HR-HPV), E6 and E7, alter the metabolic phenotype …

Human personality is 30–60% heritable according to twin and adoption studies. Hundreds of genetic variants are expected to influence its complex development, but few have been identified. We used a machine learning method for genome-wide association studies (GWAS) to uncover complex genotypic–phenotypic networks and environmental interactions. The Temperament and Character Inventory (TCI) measured the self-regulatory components of personality critical for health (i.e., the character traits of self-directedness, cooperativeness, and self-transcendence). In a discovery sample of 2149 healthy Finns, we identified sets of single-nucleotide polymorphisms (SNPs) that cluster within particular individuals (i.e., SNP sets) regardless of phenotype. Second, we identified five …

Purpose: Coronavirus disease 2019 (COVID-19) has affected millions of people all over the world with worse proven outcomes in those with certain comorbid conditions, such as diabetes, cardiovascular disease, and pulmonary complications. The Rio Grande Valley located in South Texas with a largely Hispanic population has been hit especially hard during this pandemic with over 3,200 virus-related deaths. This region’s high population of diabetic and obese patients is likely correlated with the especially high mortality rate. While it is understood the impact that obesity has on worsening health outcomes, further research is needed to better understand whether more adverse COVID-19 …
Progressive Lowering Of Transverse Mastectomy Scars Onto The Inframammary Fold: A Novel Technique To Simultaneously Improve Cosmesis While Performing Implant-Based Breast Reconstruction, Annalisa Lopez
MEDI 9331 Scholarly Activities Clinical Years
The post-reconstruction appearance of mastectomy scars is a contributing factor that affects how patients perceive themselves after breast reconstruction.1 Patients that undergo a skin-sparing mastectomy (SSM) may often have a periareolar incision which can leave an unappealing transverse scar. Regardless of whether reconstruction is performed in a delayed or immediate fashion, the transverse mastectomy scar itself commonly lies in the center of the breast near the reconstructed nipple-areolar complex, causing psychological trauma and continued patient dissatisfaction.2 This also may lead to post-reconstruction multiple mastectomy scar revisions. This research aims to describe a novel technique to reliably avoid the presence of …

School of Medicine Publications and Presentations
Objective:
A recent “bimodal-balance recovery” model suggests that contralesional influence varies based on the amount of ipsilesional reserve: inhibitory when there is a large reserve, but supportive when there is a low reserve. Here, we investigated the relationships between contralesional influence (inter-hemispheric inhibition, IHI) and ipsilesional reserve (corticospinal damage/impairment), and also defined a criterion separating subgroups based on the relationships.
Methods:
Twenty-four patients underwent assessment of IHI using Transcranial Magnetic Stimulation (ipsilateral silent period method), motor impairment using Upper Extremity Fugl-Meyer (UEFM), and corticospinal damage using Diffusion Tensor Imaging and active motor threshold. Assessments of UEFM and IHI were repeated …

Purpose: DNA damage is a continuous process occurring within the cells caused by intrinsic and extrinsic factors, but it gets repaired regularly. If the DNA repair process is faulty, the incidences of damages/mutations can accumulate in cells resulting in cell transformation. It is hypothesized that the negative variations in DNA repair pathways in even at one point viz. genetic, translational or posttranslational stage may fairly be crucial for the beginning and development of carcinogenesis. Therefore, we investigated the potential of tobacco specific nitrosamines (TSNs) related carcinogens to interact with the enzymes involved in DNA repair mechanisms in the current study. …

miRNA regulates the expression of protein coding genes and plays a regulatory role in human development and disease. The human iPSCs and their differentiated progenies provide a unique opportunity to identify these miRNA-mediated regulatory mechanisms. To identify miRNA–mRNA regulatory interactions in human nervous system development, well characterized NSCs were differentiated from six validated iPSC lines and analyzed for differentially expressed (DE) miRNome and transcriptome by RNA sequencing. Following the criteria, moderated t statistics, FDR-corrected p-value ≤ 0.05 and fold change—absolute (FC-abs) ≥2.0, 51 miRNAs and 4033 mRNAs were found to be significantly DE between iPSCs and NSCs. The miRNA target …

The increasing accuracy of algorithms to predict values and preferences raises the possibility that artificial intelligence technology will be able to serve as a surrogate decision-maker for incapacitated patients. Following Camillo Lamanna and Lauren Byrne, we call this technology the autonomy algorithm (AA). Such an algorithm would mine medical research, health records, and social media data to predict patient treatment preferences. The possibility of developing the AA raises the ethical question of whether the AA or a relative ought to serve as surrogate decision-maker in cases where the patient has not issued a medical power of attorney. We argue that …

Introduction: The novel coronavirus (CoV) disease 2019 (COVID-19) is a viral infection that causes Severe Acute Respiratory Syndrome. It is believed that early reports of COVID-19 cases were noticed in December 2019 and soon after became a global public health emergency. It is advised that COVID-19 transmits through human to human contact and in most cases it remains asymptomatic. Several approaches are being utilized to control the outbreak of this fatal viral disease. microRNAs (miRNAs) are known signature therapeutic tool for the viral diseases; they are small non-coding RNAs that target the mRNAs to inhibit their post-transcriptional expression, therefore, impeding …

Cortical folds help drive the parcellation of the human cortex into functionally specific regions. Variations in the length, depth, width, and surface area of these sulcal landmarks have been associated with disease, and may be genetically mediated. Before estimating the heritability of sulcal variation, the extent to which these metrics can be reliably extracted from in-vivo MRI must be established. Using four independent test-retest datasets, we found high reliability across the brain (intraclass correlation interquartile range: 0.65–0.85). Heritability estimates were derived for three family-based cohorts using variance components analysis and pooled (total N > 3000); the overall sulcal heritability pattern was …

Objective
To determine 2020 residency cycle application practices and to model potential consequences in the 2021 cycle if (1) applicants scheduled an uncapped number of interviews; (2) applicants were capped to schedule 12 interviews; (3) residency programs kept their number of interview offers unchanged; and (4) programs increased their interview offers by 20%.
Design and Setting
The authors sent an anonymous survey to all obstetrics and gynecology applicants registered through the Electronic Residency Application Service in February 2020 asking respondents to share demographics and number of interview offers received and completed. Based on prior estimates that 12 interviews are needed …
