Publications and Research

Traumatic brain injury (TBI) is highly prevalent in adults. TBI-related functional brain alterations have been linked with common post-TBI neurobehavioral sequelae, with unknown neural substrates. This study examined the systems-level functional brain alterations in white matter (WM) and gray matter (GM) for visual sustained-attention processing, and their interactions and contributions to post-TBI attention deficits. Task-based functional MRI data were collected from 42 adults with TBI and 43 group-matched normal controls (NCs), and analyzed using the graph theoretic technique. Global and nodal topological properties were calculated and compared between the two groups. Correlation analyses were conducted between the neuroimaging measures that …

Cryptococcus Neoformans Melanization Incorporates Multiple Catecholamines To Produce Polytypic Melanin, Rosanna P. Baker, Christine Chrissian, Ruth E. Stark, Arturo Casadevall

Publications and Research

Melanin is a major virulence factor in pathogenic fungi that enhances the ability of fungal cells to resist immune clearance. Cryptococcus neoformans is an important human pathogenic fungus that synthesizes melanin from exogenous tissue catecholamine precursors during infection, but the type of melanin made in cryptococcal meningoencephalitis is unknown. We analyzed the efficacy of various catecholamines found in brain tissue in supporting melanization using animal brain tissue and synthetic catecholamine mixtures reflecting brain tissue proportions. Solid-state NMR spectra of the melanin pigment produced from such mixtures yielded more melanin than expected if only the preferred constituent dopamine had been incorporated, …

From Burnout To Occupational Depression: Recent Developments In Research On Job-Related Distress And Occupational Health, Irvin Sam Schonfeld, Renzo Bianchi

Publications and Research

Job-related distress has been a focal concern in occupational health science. Job-related distress has a well-documented health-damaging and life-threatening character, not to mention its economic cost. In this article, we review recent developments in research on job-related distress and examine ongoing changes in how job-related distress is conceptualized and assessed. By adopting an approach that is theoretically, empirically, and clinically informed, we demonstrate how the construct of burnout and its measures, long favored in research on job-related distress, have proved to be problematic. We underline a new recommendation for addressing job-related distress within the long-established framework of depression research. In …

Caregiver Decision-Making Concerning Involuntary Treatment In Dementia Care At Home, Vincent Ra Moermans, Angela Mhj Mengelers, Michel Hc Bleijlevens, Hilde Verbeek, Bernadette Dierckx De Casterle, Koen Milisen, Elizabeth Capezuti, Jan Ph Hamers

Exploration Of Dark Chemical Genomics Space Via Portal Learning: Applied To Targeting The Undruggable Genome And Covid-19 Anti-Infective Polypharmacology, Tian Cai, Li Xie, Muge Chen, Yang Liu, Di He, Shuo Zhang, Cameron Mura, Philip Boume, Lei Xie

Publications and Research

Advances in biomedicine are largely fueled by exploring uncharted territories of human biology. Machine learning can both enable and accelerate discovery, but faces a fundamental hurdle when applied to unseen data with distributions that differ from previously observed ones—a common dilemma in scientific inquiry. We have developed a new deep learning framework, called Portal Learning , to explore dark chemical and biological space. Three key, novel components of our approach include: (i) end-to-end, step-wise transfer learning, in recognition of biology’s sequence-structure-function paradigm, (ii) out-of-cluster meta-learning, and (iii) stress model selection. Portal Learning provides a practical solution to the out-of-distribution (OOD) …

Expanding The Conceptualization Of Support In Low-Wage Carework: The Case Of Home Care Aides And Client Death, Emma K. Tsui, Marita Lamonica, Maryam Hyder, Paul Landsbergis, Jennifer Zelnick, Sherry Baron

Publications and Research

Home care aides are a rapidly growing, non-standard workforce who face numerous health risks and stressors on the job. While research shows that aides receive limited support from their agency employers, few studies have explored the wider range of support that aides use when navigating work stress and considered the implications of these arrangements. To investigate this question, we conducted 47 in-depth interviews with 29 home care aides in New York City, focused specifically on aides’ use of support after client death. Theories of work stress, the social ecological framework, and feminist theories of care informed our research. Our analysis …

A Closer Look At The Aha's Antibiotic Prophylaxis Guidelines, Dora-Ann Oddo

Publications and Research

In May 2021, the American Heart Association (AHA) updated its antibiotic prophylaxis guidelines for the prevention of infective endocarditis (IE). As some dental and dental hygiene procedures may increase the risk of this potentially life-threatening infection in at-risk patients, oral health professionals must have a thorough understanding of this serious, albeit rare infection of the heart and understand appropriate precautions for treatment. This article focuses on the AHA's guidelines; however, oral health professionals should also consider the IE guidelines from the American Academy of Orthopedics Surgeons.

Publications and Research

Background. The current Coronavirus pandemic has been linked to a dramatic increase in anti-Asian American and Pacific Islander (AAPI) hate incidents in the United States. At the time of writing, there does not appear to be any published empirical research examining the mechanisms underlying Asiaphobia during the current pandemic. Based on the stereotype content model, we investigated the idea that ambivalent attitudes toward AAPIs, marked primarily with envy, may be contributing to anti-AAPI xenophobia. Methods. Study 1 (N = 140) explored, through a survey, the link between envious stereotypes toward AAPIs and Asiaphobia. Study 2 (N = 167), …

Stimulating The Facial Nerve To Treat Ischemic Stroke: A Systematic Review, Turner S. Baker, Justin Robeny, Danna Cruz, Alexis Bruhat, Alfred-Marc Iloreta, Anthony Costa, Thomas James Oxley

Publications and Research

Acute ischemic stroke (AIS) is a common devastating disease that has increased yearly in absolute number of cases since 1990. While mechanical thrombectomy and tissue plasminogen activator (tPA) have proven to be effective treatments, their window-of-efficacy time is very short, leaving many patients with no viable treatment option. Over recent years there has been a growing interest in stimulating the facial nerves or ganglions to treat AIS. Pre-clinical studies have consistently demonstrated an increase in collateral blood flow (CBF) following ganglion stimulation, with positive indications in infarct size and neurological scores. Extensive human trials have focused on trans-oral electrical stimulation …

Insights Into Using Plants In Management Of Viral Diseases., Vyacheslav Dushenkov, Anna Dushenkov

Publications and Research

Botanical therapeutics possess a unique potential in the treatment of viral diseases. The pharmacological base and clinical use of botanical therapeutics have been extensively reviewed. The mode of action(s) may be built either on the direct interference with the virus's ability to enter human cells, virus replication, or exerting immune-modulatory and anti-inflammatory effects. The adjuvant treatment with botanical therapeutics has the potential to result in advances in symptom resolution, decrease in disease burden and shortening its duration.

How Can I Get Covid?: Understanding Diferences In American Heterosexual And Sexual Minority Men’S Risk Perception, Devon M. Price, Amanda N. Gesselman, Rachel A. Fikslin, Alison J. Goldberg, Omaima Pervez, Mora A. Reinka, Elissia Franklin

Publications and Research

Men are more vulnerable to COVID-19 infections compared to women, but their risk perceptions around COVID-19 are persis - tently lower. Further, men often engage in less health promotion behavior because self-care in this capacity is seen as weak or less masculine. This combination has consequences for mortality; thus, a better understanding of men’s COVID-19 cognitions and individual diference factors is critical. In a web-based survey conducted during the beginning stages of the pandemic in the U.S., we collected risk perceptions of various sexual and non-sexual behaviors from heterosexual ( n = 137) and gay/bisexual men ( n = 108). …

Treatment Selection Using Prototyping In Latent-Space With Application To Depression Treatment, Akiva Kleinerman, Ariel Rosenfeld, David Benrimoh, Robert Fratila, Caitrin Armstrong, Joseph Mehltretter, Eliyahu Shneider, Amit Yaniv-Rosenfeld, Jordan Karp, Charles F. Reynolds, Gustavo Turecki, Adam Kapelner

Publications and Research

Machine-assisted treatment selection commonly follows one of two paradigms: a fully personalized paradigm which ignores any possible clustering of patients; or a sub-grouping paradigm which ignores personal differences within the identified groups. While both paradigms have shown promising results, each of them suffers from important limitations. In this article, we propose a novel deep learning-based treatment selection approach that is shown to strike a balance between the two paradigms using latent-space prototyping. Our approach is specifically tailored for domains in which effective prototypes and sub-groups of patients are assumed to exist, but groupings relevant to the training objective are not …

Publications and Research

The gram-negative bacterium Vibrio cholerae is the causative agent of the diarrhoeal disease cholera and is responsible for seven recorded pandemics. Several factors are postulated to have led to the decline of 6th pandemic classical strains and the rise of El Tor biotype V. cholerae, establishing the current 7th pandemic. We investigated the ability of classical V. cholerae of the 2nd and 6th pandemics to engage their type six secretion system (T6SS) in microbial competition against non-pandemic and 7th pandemic strains. We report that classical V. cholerae underwent sequential mutations in T6SS genetic determinants that initially exposed 2nd pandemic strains …

The Temperature-Dependent Conformational Ensemble Of Sars-Cov-2 Main Protease (Mpro), Ali Ebrahim, Blake T. Riley, Desigan Kumaran, Babak Andi, Martin R. Fuchs, Sean Mcsweeney, Daniel A. Keedy

Publications and Research

The COVID-19 pandemic, instigated by the SARS-CoV-2 coronavirus, continues to plague the globe. The SARS-CoV-2 main protease, or M^pro, is a promising target for development of novel antiviral therapeutics. Previous X-ray crystal structures of M^pro were obtained at cryogenic temperature or room temperature only. Here we report a series of high-resolution crystal structures of unliganded M^pro across multiple temperatures from cryogenic to physiological, and another at high humidity. We interrogate these datasets with parsimonious multiconformer models, multi-copy ensemble models, and isomorphous difference density maps. Our analysis reveals a temperature-dependent conformational landscape for M^pro, including …

We conducted a retrospective analysis of 2584 cases initiated by Physicians for Human Rights between 2008-2018 that included forensic medical evaluations, and found that 81.6% of applicants for various forms of immigration relief were granted relief, as compared to the national asylum grant rate of 42.4%. Among the study’s cohort, the majority (73.7%) of positive outcomes were grants of asylum. A multivariable regression analysis revealed …

Changes In Histone H3 Acetylation On Lysine 9 Accompany Aβ 1-40 Overexpression In An Alzheimer’S Disease Yeast Model, Muna M. Hugais, Samantha N. Cobos, Seth A. Bennett, Jailene Paredes, Genevieve Foran, Mariana P. Torrente

Publications and Research

Alzheimer’s Disease (AD), the most common type of dementia, is a neurodegenerative disease characterized by plaques of amyloid-beta (Aβ) peptides found in the cerebral cortex of the brain. The pathological mechanism by which Aβ aggregation leads to neurodegeneration remains unknown. Interestingly, genetic mutations do not explain most AD cases suggesting that other mechanisms are at play. Epigenetic mechanisms, such as histone post-translational modifications (PTMs), may provide insight into the development of AD. Here, we exploit a yeast Aβ overexpression model to map out the histone PTM landscape associated with AD. We find a modest decrease in the acetylation levels on …

Psychosocial Factors Associated With Mask-Wearing Behavior During The Covid-19 Pandemic, Cliff (Yung-Chi) Chen, Mengjia Lei

Publications and Research

Although increasing evidence has supported the efficacy of masks to prevent the spread of the coronavirus (COVID-19), inconsistent and noncompliant mask-wearing behavior has been observed among members of the society. Because mask-wearing is often considered a social contract, it is important to understand the psychosocial factors that influence people’s mask-wearing behavior in order to implement the necessary steps to respond to the pandemic. Based on the protection motivation theory (PMT), this study examined the cognitive factors (threat and coping appraisals) that contribute to mask-wearing behavior and the intention to engage in health protective behavior until the end of the pandemic. …

Addressing Structural Racism In The Health Workforce, Randl B. Dent, Anushree Vichare, Jaileessa Casimir

Publications and Research

One of the greatest challenges facing the United States are health inequities among racial/ethnic and other marginalized populations. The deep-rooted structural racism embedded in our social systems, including our health care system and health workforce, is a core cause of racial health inequities. 1 Among many definitions of institutionalized or structural racism, Dr Jones 2 best defines it as: “Differential access to goods, services and opportunities of society by race ... It is structural, having been codified in our institutions of custom, practice, and law, so there need not be an identifiable perpetrator.” Dr Jones further explains that to set …
