An Exploratory Study Of Police Officers: Low Compassion Satisfaction And Compassion Fatigue, Heath Blair Grant, Cathryn F. Lavery, John Decarlo

Publications and Research

Background: Compassion fatigue, or the physical, mental, and emotional state experienced by professionals that assist others in distress, has been well documented in several caring professions such as nurses, firefighters, and emergency medical technicians. Until the current study, it has only rarely been examined in police samples despite their high rates of stress and suicide which is a likely result of a depletion of compassion satisfaction, or the pleasure an officer gets from relating to and helping others.

Aim: This study documents findings from an ongoing study of compassion fatigue amongst a sample of US urban police officers which suggests …

Effects Of Am80 Compared To Ac261066 In A High Fat Diet Mouse Model Of Liver Disease, Marta Melis, Xiao-Han Tang, Steven E. Trasino, Viral M. Patel, Daniel J. Stummer, Jose Jessurun, Lorraine J. Gudas

Publications and Research

The roles of retinoids in nonalcoholic fatty liver disease (NAFLD) remain unclear and a better understanding may lead to therapies that prevent or limit NAFLD progression. We examined the actions of retinoic acid receptor (RAR) agonists- AM80 for RARαand AC261066 for RARβ2- in a murine model of NAFLD. We fed wild type C57Bl/6 mice a chow or a 45% high fat diet (HFD) for 12 weeks, followed by 4 additional weeks with the HFD+AM80; HFD +AC261066; or HFD. The HFD+AM80 group showed greater hyperglycemia and glucose intolerance compared to other groups. Histopathological evaluation of the livers showed the highest degree …

Biotransformed Metabolites Of The Hop Prenylflavanone Isoxanthohumol, Hyun Jung Kim, Soon-Ho Yim, Fubo Han, Bok Yun Kang, Hyun Jin Choi, Da-Woon Jung, Darren R. Williams, Kirk R. Gustafson, Edward J. Kennelly, Ik-Soo Lee

Publications and Research

A metabolic conversion study on microbes is known as one of the most useful tools to predict the xenobiotic metabolism of organic compounds in mammalian systems. The microbial biotransformation of isoxanthohumol (1), a major hop prenylflavanone in beer, has resulted in the production of three diastereomeric pairs of oxygenated metabolites (2–7). The microbial metabolites of 1 were formed by epoxidation or hydroxylation of the prenyl group, and HPLC, NMR, and CD analyses revealed that all of the products were diastereomeric pairs composed of (2S)- and (2R)- isomers. The structures of these metabolic compounds were elucidated to be (2S,200S)- and (2R,200S)-40 …

Microrna-4719 And Microrna-6756-5p Correlate With Castration-Resistant Prostate Cancer Progression Through Interleukin-24 Regulation, Dibash K. Das, Leah Persaud, Moira Sauane

Publications and Research

Prostate cancer (PCa) is the second leading cause of cancer death in the United States. The five-year survival rate for men diagnosed with localized PCa is nearly 100%, yet for those diagnosed with aggressive PCa, it is less than 30%. The pleiotropic cytokine Interleukin-24 (IL-24) has been shown to specifically kill PCa cells compared to normal cells when overexpressed in both in vitro and in vivo studies. Despite this, the mechanisms regulating IL-24 in PCa are not well understood. Since specific microRNAs (miRNAs) are dysregulated in PCa, we used miRNA target prediction algorithm tools to identify miR-4719 and miR-6556-5p as …

A Writing Assignment To Address Gaps In The Nursing Curriculum Regarding Health Issues Of Lgbt+ Populations., Bridget Maley, Randy Gross

Publications and Research

Background: LGBT+ populations account for 4% of the US population, yet health disparities persist, which are considered a priority in health care systems. In nursing education programs, the allotment in time to cover LGBT+ health content is not mandated thus ranges from zero to several hours total in nursing curricula. Therefore, nursing students’ education regarding LGBT+ health issues remains minimal and inconsistent throughout the nation’s nursing programs.

Aim: To provide associate degree nursing students with exposure to the health disparities in LGBT+ populations through a reflective writing assignment.

Methods: The essays were culled from both sections of an established core …

Adolescent Trials Network For Hiv-Aids Scale It Up Program: Protocol For A Rational And Overview, Sylvie Naar, Jeffrey T. Parsons, Bonita F. Stanton

Publications and Research

Background: The past 30 years have witnessed such significant progress in the prevention and treatment of HIV/AIDS that an AIDS-free generation and the end to the global AIDS epidemic are ambitious, but achievable, national and global goals. Despite growing optimism, globally, youth living with HIV are markedly less likely to receive antiretroviral therapy than adults (23% vs 38%). Furthermore, marked health disparities exist regarding HIV infection risk, with young men of color who have sex with men disproportionately affected. A large body of research has identified highly impactful facilitators of and barriers to behavior change. Several efficacious interventions have been …

Publications and Research

Purpose: The purpose of this study was to evaluate muscular adaptations between low-, moderate-, and high-volume resistance training protocols in resistance-trained men.

Methods: Thirty-four healthy resistance-trained men were randomly assigned to one of three experimental groups: a low-volume group performing one set per exercise per training session (n = 11), a moderate-volume group performing three sets per exercise per training session (n = 12), or a high-volume group performing five sets per exercise per training session (n = 11). Training for all routines consisted of three weekly sessions performed on nonconsecutive days for 8 wk. Muscular strength was evaluated with …

Large Pelvic Tubercle In Orangutans Relates To The Adductor Longus Muscle, Brian M. Shearer, Magdalena Muchlinski, Ashley S. Hammond

Publications and Research

Orangutan pelves commonly exhibit a large, projecting tubercle in the iliopubic region, historically assumed to homologous to the pubic tubercle in humans. However, it is not clear whether this tubercle is a unique feature of Pongo, or if it is anatomically homologous with the human pubic tubercle when considered as a soft tissue attachment point. To clarify this issue, we dissected orangutan and other ape cadaveric specimens to evaluate the pelvic brim soft tissues and how they may relate to the tubercle (when present). We additionally conducted a broad osteological survey of pelvic brim morphology across 28 primate genera …

An Ensemble Of Flexible Conformations Underlies Mechanotransduction By The Cadherin–Catenin Adhesion Complex, Martin Bush, Bashir M. Alhanshali, Shuo Qian, Christopher B. Stanley, William T. Heller, Tsutomu Matsui, Thomas M. Weiss, Iain D. Nicholl, Thomas Walz, David J. E. Callaway, Zimei Bu

Publications and Research

The cadherin–catenin adhesion complex is the central component of the cell–cell adhesion adherens junctions that transmit mechanical stress from cell to cell. We have determined the nanoscale structure of the adherens junction complex formed by the α-catenin•β-catenin•epithelial cadherin cytoplasmic domain (ABE) using negative stain electron microscopy, small-angle X-ray scattering, and selective deuteration/small-angle neutron scattering. The ABE complex is highly pliable and displays a wide spectrum of flexible structures that are facilitated by protein-domain motions in α- and β-catenin. Moreover, the 107-residue intrinsically disordered N-terminal segment of β-catenin forms a flexible “tongue” that is inserted into α-catenin and participates in the …

The Trouble With Burnout: An Update On Burnout-Depression Overlap, Renzo Bianchi, Irvin Sam Schonfeld, Eric Laurent

Publications and Research

Reducing depression to its clinical stage—to a nosological category—is unwarranted when examining the burnout-depression distinction. Recent factor analytic studies of burnout and depression measures indicate that the discriminant validity of the burnout construct is not satisfactory. Exhaustion—the core and only consensual characteristic of burnout—has been repeatedly found to correlate more strongly with depression (including anhedonia and depressed mood) than with the two other components of burnout (cynicism and professional inefficacy).

An Exploratory Structural Equation Modeling Bi-Factor Analytic Approach To Uncovering What Burnout, Depression, And Anxiety Scales Measure, Irvin Sam Schonfeld, Jay Verkuilen, Renzo Bianchi

Publications and Research

In this study, we addressed the ongoing debate about what burnout and depression scales measure by conducting an exploratory structural equation modeling (ESEM) bifactor analysis. A sample of 734 U.S. teachers completed a survey that included the Center for Epidemiologic Studies Depression scale (CES-D-10), the depression module of the Patient Health Questionnaire (PHQ-9), the Generalized Anxiety Disorder scale (GAD-7), and the Maslach Burnout Inventory (MBI), which contains emotional exhaustion (EE), depersonalization (DP), and (diminished) personal accomplishment (PA) subscales. Job adversity and workplace support were additionally measured for the purpose of a nomological network analysis. EE, burnout’s core, was more highly …

BACKGROUND: The United States Centers for Disease Control and Prevention estimates that approximately 60,000 US youth are living with HIV. US youth living with HIV (YLWH) have poorer outcomes compared with adults, including lower rates of diagnosis, engagement, retention, and virologic suppression. With Adolescent Medicine Trials Network for HIV/AIDS Interventions (ATN) support, new trials of youth-centered interventions to improve retention in care and medication adherence among YLWH are underway.

OBJECTIVE: This study aimed to use a computer simulation model, the Cost-Effectiveness of Preventing AIDS Complications (CEPAC)-Adolescent Model, to evaluate selected ongoing and forthcoming ATN interventions to improve viral load suppression …

Associations Of Hemoglobin A1c With Cognition Reduced For Long Diabetes Duration, Jeremy M. Silverman, James Schmeidler, Pearl G. Lee, Neil B. Alexander, Michal Schnaider Beeri, Elizabeth Guerrero-Berroa, Rebecca K. West, Mary Sano, Martina Nabozny, Carolina Rodriguez Alvarez

Publications and Research

Introduction: Associations of some risk factors with poor cognition, identified prior to age 75, are reduced or reversed in very old age. The Protected Survivor Model predicts this interaction due to enhanced survival of those with extended risk factor duration. In a younger sample, this study examines the association of cognition with the mean hemoglobin A1c risk factor over the time at risk, according to its duration.

Methods: The interaction of mean hemoglobin A1c (average = 9.8%), evaluated over duration (average = 116.8 months), was examined for overall cognition and three cognitive domains in a sample of 150 “young-old” veterans …

Publications and Research

The purpose of this study was to determine the effects of different amounts of energy intake in combination with progressive resistance training on muscle mass and body fat in bodybuilders. Eleven male bodybuilders (26.8 ± 2.3 years, 90.1 ± 9.7 kg, and 176.9 ± 7.1 cm) were randomly assigned into one of two groups: a group that ingested higher amounts of energy (G1, 67.5 ± 1.7 kcal/kg/d, n = 6), and a group that ingested moderate amounts of energy (G2, 50.1 ± 0.51 kcal/kg/d, n = 5). Both groups performed resistance training 6 days per week over a 4-week study …

Response To "From A Polemic Paradox To A Proper Perspective Of Job Burnout And Job Satisfaction, Eric Laurent, Irvin Sam Schonfeld, Renzo Bianchi

Publications and Research

Juárez García and colleagues considered that “part of the conceptual and empirical problem of burnout is that many researchers force it into a biomedical disease model despite its being a psychosocial one.” Problematically, these authors’ scholastic argument a priori excludes biological or bodily factors from psychological conceptualizations. Scientists usually face considerable difficulties when trying to describe complex processes. If the understanding of biological processes sheds light on the complex processes that bear on burnout, then there is no reason to exclude research on those processes.

Examining Motivational Interviewing's Effect On Confidence And Commitment Using Daily Data, Alexis Kuerbis, Kevin Lynch, Sijing Shao, Jon Morgenstern

Publications and Research

Mechanisms of behavior change (MOBC) within Motivational Interviewing (MI) are thought to operate via both relational and technical elements. These elements are hypothesized to increase client motivation and self-efficacy for change and subsequently decrease drinking. Only partial support for this causal chain exists, particularly when using within-session change talk as the primary intervening variable. This study explored whether commitment to moderate or abstain from drinking and confidence to moderate drinking in the next day measured via ecological momentary assessment (EMA) provided alternative support for the theory. Data were from a pilot randomized controlled trial testing active ingredients of MI. Problem …

Clinic-Based Delivery Of The Young Men’S Health Project (Ymhp) Targeting Hiv Risk Reduction And Substance Use Among Young Men Who Have Sex With Men: Protocol For A Type 2, Hybrid Implementation-Effectiveness Trial, Jeffrey T.

Spinal Matrix Metalloproteinase 8 Regulates Pain After Peripheral Trauma, Maral Tajerian, J. David Clark

Publications and Research

It is well documented that pain chronification requires a host of plastic mechanisms at the spinal cord (SC) level, including alterations in neuronal and glial structure and function. Such cellular plasticity necessitates the existence of a plastic extracellular matrix(ECM). Here, we describe a key role for ECM remodeling in the regulation of chronic pain following peripheral injury. Three weeks following tibia fracture in mice, we show increased levels of MMP8 in the SC. Furthermore, we show that the pharmacological or genetic downregulation of MMP8 ameliorates the pain phenotype observed after injury. These results delineate an extracellular mechanism for pain chronification, …

Does Widowhood Affect Cognitive Function Among Chinese Older Adults?, Zhenmei Zhang, Lydia W. Li, Hongwei Xu, Jinyu Liu

Publications and Research

There is growing evidence from Western countries that widowhood may affect cognitive health in later life. However, little is known about whether widowhood isassociated with cognitive health in Eastern Asian countries such as China and what factors may explain the association between widowhood and cognitive health. Weadd to this line of research by investigating the effect of widowhood on 2-year change in cognitive function among Chinese adults ages 55 and older from 2011 to2013, using data from the China Health and Retirement Longitudinal Study. Cognitive function was measured by episodic memory and mental intactness (i.e.,attention and time orientation). Our results …

Inquiry Into The Correlation Between Burnout And Depression, Irvin Sam Schonfeld, Jay Verkuilen, Renzo Bianchi

Publications and Research

The extent to which burnout refers to anything other than a depressive condition remains an object of controversy among occupational health specialists. In three studies conducted in two different countries and two different languages, we investigated the discriminant validity of burnout scales by evaluating the magnitude of the correlation between (latent) burnout and (latent) depression. In Study 1 (N = 911), burnout was assessed with the Maslach Burnout Inventory–General Survey’s Exhaustion subscale and depression with the depression module of the Patient Health Questionnaire (PHQ). In Study 2 (N = 1,386), the Shirom–Melamed Burnout Measure was used to assess burnout and …

Sonic Hedgehog Is Expressed By Hilar Mossy Cells And Regulates Cellular Survival And Neurogenesis In The Adult Hippocampus, Luis E. Gonzalez-Reyes, Chia-Chu Chiang, Mingming Zhang, Joshua Johnson, Manuel Arrillaga-Tamez, Nicholas H. Couturier, Neha Reddy, Lev Starikov, Jeffrey R. Capadona, Andreas H. Kottmann, Dominique M. Durand

Publications and Research

Sonic hedgehog (Shh) is a multifunctional signaling protein governing pattern formation, proliferation and cell survival during embryogenesis. In the adult brain, Shh has neurotrophic function and is implicated in hippocampal neurogenesis but the cellular source of Shh in the hippocampus remains ill defined. Here, we utilize a gene expression tracer allele of Shh (Shh-nlacZ) which allowed the identification of a subpopulation of hilar neurons known as mossy cells (MCs) as a prominent and dynamic source of Shh within the dentate gyrus. AAV-Cre mediated ablation of Shh in the adult dentate gyrus led to a marked degeneration …

Burnout: Moving Beyond The Status Quo, Renzo Bianchi, Irvin Sam Schonfeld, Éric Laurent

Publications and Research

Burnout has been defined as a job-induced syndrome combining emotional exhaustion, depersonalization/cynicism, and a sense of reduced personal accomplishment. In this article, we expand on past analyses of burnout by reviewing key, yet overlooked, problems affecting the construct. We concomitantly examine the implications of these problems for the overall validity of burnout research. Our work shows that burnout research is undermined by 4 main problems. First, what constitutes a case of burnout is unclear. Second, the basic conceptualization and operationalization of burnout are ill aligned. Third, burnout is unlikely to be the specifically job-induced syndrome it has been posited to …

Using Physical Contact Heterogeneity And Frequency To Characterize Dynamics Of Human Exposure To Nonhuman Primate Bodily Fluids In Central Africa, Victor Narat, Mamdou Kampo, Thibut Heyer, Stephanie Rupp, Philippe Ambata, Richard Njouom, Tamara Giles-Vernick

Publications and Research

Emerging infectious diseases of zoonotic origin constitute a recurrent threat to global health. Nonhuman primates (NHPs) occupy an important place in zoonotic spillovers (pathogenic transmissions from animals to humans), serving as reservoirs or amplifiers of multiple neglected tropical diseases, including viral hemorrhagic fevers and arboviruses, parasites and bacteria, as well as retroviruses (simian foamy virus, PTLV) that are pathogenic in human beings. Hunting and butchering studies in Africa characterize at-risk human social groups, but overlook critical factors of contact heterogeneity and frequency, NHP species differences, and meat processing practices. In southeastern Cameroon, a region with a history of zoonotic emergence …
