Community-Based Responses To Negative Health Impacts Of Sexual Humanitarian Anti-Trafficking Policies And The Criminalization Of Sex Work And Migration In The Us, Heidi Hoefinger, Jennifer Musto, P.G. Macioti, Anne E. Fehrenbacher, Nicola Mai, Calum Bennachie, Calogero Giametta

Publications and Research

System-involvement resulting from anti-trafficking interventions and the criminalization of sex work and migration results in negative health impacts on sex workers, migrants, and people with trafficking experiences. Due to their stigmatized status, sex workers and people with trafficking experiences often struggle to access affordable, unbiased, and supportive health care. This paper will use thematic analysis of qualitative data from in-depth interviews and ethnographic fieldwork with 50 migrant sex workers and trafficked persons, as well as 20 key informants from legal and social services, in New York and Los Angeles. It will highlight the work of trans-specific and sex worker-led initiatives …

Part I: Comparative Analysis Between Natural And Ceramic Teeth, Aneeza Hussain, Ibeth Erazo

Publications and Research

Ceramics play a fundamental role in Dentistry and are used widely, due to their ability to mimic the optical characteristics of enamel and dentine, as well as for their biocompatibility and strength. Initially, dental ceramics were materials that formed part of systems, designed with the purpose of producing dental prosthetics that in turn were used to replace missing or damaged dental structures. However, due to the increased demand for esthetics, its development has gone beyond in such a way that it has led to the development of all ceramic restorations. So that, in the last few decades, there have been …

College Students And Snap: The New Face Of Food Insecurity In The United States, Nicholas Freudenberg, Sara Goldrick-Rab, Janet Poppendieck

Publications and Research

Over the last decade, multiple studies of food insecurity among college students have found rates from 20% to more than 50%, considerably higher than the 12% rate for the entire US population.

Reasons for higher rates of food insecurity among college students include a growing population of low-income college students, high college costs and insufficient financial aid, more financial hardship among many low- and moderate-income families, a weak labor market for part-time workers, declining per capita college resources, and Supplemental Nutritional Assistance Program (SNAP) policies that specifically exclude many college students from participation.

This essay reviews the causes and consequences …

Tamoxifen Activity Against Plasmodium In Vitro And In Mice, Ada Weinstock, Julio Gallego-Delgado, Cláudia Gomes, Julian Sherman, Cyrus Nikain, Sandra Gonzalez, Edward Fisher, Ana Rodriguez

Publications and Research

Background: Tamoxifen is an oestrogen receptor modulator that is widely used for the treatment of early stage breast cancer and reduction of recurrences. Tamoxifen is also used as a powerful research tool for controlling gene expression in the context of the Cre/loxP site-specific recombination system in conditional mutant mice.

Methods: To determine whether the administration of tamoxifen affects Plasmodium growth and/or disease outcome in malaria, in vitro studies assessing the effect of tamoxifen and its active metabolite 4-hydroxytamoxifen on Plasmodium falciparum blood stages were performed. Tamoxifen effects were also evaluated in vivo treating C57/B6 mice infected with Plasmodium berghei (ANKA …

Publications and Research

Background:

Men who have sex with men (MSM) continue to be the predominately impacted risk group in the United States HIV epidemic and are a priority group for risk reduction in national strategic goals for HIV prevention. Modeling studies have demonstrated that a comprehensive package of status-tailored HIV prevention and care interventions have the potential to substantially reduce new infections among MSM. However, uptake of basic prevention services, including HIV testing, sexually transmitted infection (STI) testing, condom distribution, condom-compatible lubricant distribution, and preexposure prophylaxis (PrEP), is suboptimal. Further, stronger public health strategies are needed to promote engagement in HIV care …

Suicide Among Persons Who Entered Same-Sex And Opposite-Sex Marriage In Denmark And Sweden, 1989–2016: A Binational, Register-Based Cohort Study, Annette Erlangsen, Sven Drefahl, Ann Haas, Charlotte Bjorkenstam, Merete Nordentoft, Gunnar Andersson

Publications and Research

Background

People belonging to sexual minority groups have higher levels of suicidality than heterosexuals. However, findings regarding suicide death are sparse. Using unique national data from two countries, we investigated whether individuals entering a same-sex marriage (SSM), a proxy group of sexual minority individuals, had higher suicide rates than those entering opposite-sex marriage (OSM).

Methods

A cohort study of all males and females who entered an SSM (n=28 649) or OSM (n=3 918 617) in Denmark and Sweden during 1989–2016 was conducted. Incidence rate ratios (IRRs) for suicide were calculated using adjusted Poisson regression models.

Results

In total, 97 suicides …

Public Health Research Priorities To Address Female Genital Mutilation Or Cutting In The United States, Holly G. Atkinson, Deborah Ottenheimer, Ranit Mishori

Publications and Research

Female genital mutilation or cut- ting (FGM/C), an age-old tradition that is still widely practiced around the world, is gaining recognition as an important public health issue in the United States. Increasingly, because of migration, women and girls affected by FGM/C have become members of host communities where the practice is not culturally acceptable.

According to recent conservative estimates, more than 513 000 immigrant women and girls living in the United States have undergone or are at risk for FGM/C, a significant increase from the 1990 estimate of 168 000. The arrests of physicians in Michigan in 2017 for performing …

The Concurrent Decline Of Soil Lead And Children’S Blood Lead In New Orleans, Howard W. Mielke, Christopher R. Gonzales, Eric T. Powell, Mark A. S. Laidlow, Kenneth J. Berry, Paul W. Mielke Jr., Sara Perl Egendorf

Publications and Research

Lead (Pb) is extremely toxic and a major cause of chronic diseases worldwide. Pb is associated with health disparities, particularly within low-income populations. In biological systems, Pb mimics calcium and, among other effects, interrupts cell signaling. Furthermore, Pb exposure results in epigenetic changes that affect multigenerational gene expression. Exposure to Pb has decreased through primary prevention, including removal of Pb solder from canned food, regulating lead-based paint, and especially eliminating Pb additives in gasoline. While researchers observe a continuous decline in children’s blood lead (BPb), reservoirs of exposure persist in topsoil, which stores the legacy dust from leaded gasoline and …

From The Human To The Planetary: Speculative Futures Of Care, Miriam Ticktin

Publications and Research

This is largely a theoretical, speculative essay that takes on the question of what ‘care’ looks like at a moment when climate change is increasingly taking center stage in public and political discussions. Starting with two new practices, namely, humanitarian care for nonhumans and One Health collaborations, I seek to determine what forms of political care can incorporate the well-being of future generations and future iterations of the earth. After an exploration of One Health as an approach to planetary care, I ask what its parts enable us to think, despite its limitations; I focus on the new human-nonhuman assemblages …

Evaluation Of Mitral Apparatus Blood Cyst: A Case Report And Review Of Literature, Dipesh Ludhwani, Belaal Sheikh, Yahya Sheikh

Publications and Research

Intracardiac blood cysts (ICBC) are cardiac pseudoneoplasm commonly seen in infants below two months of age. ICBC typically resolve spontaneously; however, they can sometimes persist in adults and can cause detrimental consequences. A 47-year-old female presented to our facility with complaints of chest pain and was found to have an incidental subvalvular chordal mitral apparatus echolucent mass on transthoracic echocardiogram (TTE). A stress echocardiography was performed, which revealed transient left ventricle outflow tract (LVOT) obstruction in the absence of anginal symptoms. A cardiac magnetic resonance imaging (MRI) showed no evidence of increased mass enhancement confirming the diagnosis of a benign …

Medical Dental Device: Biogeneric Implant Prototype, Ibeth Erazo, Aneeza Hussain, Renata Budny, Gaffar Gailani

Publications and Research

Teeth are lost due to tooth decay, injury, disease, or other causes. Today, dental implants extend the range of care to a variety of patients undergoing necessary prosthodontic rehabilitation. If the benefits of such treatments are to be maximized, then implants must be selected on logical basis and placed within the context of the full range of treatment modalities. However, modern dental implant systems are based on multiple components often leading to micro-movements which cause stress on the bone or bacterial infections, both of which compromise the success of osseointegration and consequently jeopardize the whole implant adaptation. Thus, a new …

The Huntingtin Inclusion Is A Dynamic Phase-Separated Compartment, Fahmida Aktar, Chakkapong Burudpakdee, Mercedes Polanco, Sen Pei, Theresa C. Swayne, Peter N. Lipke, Lesley Emtage

Publications and Research

Inclusions of disordered protein are a characteristic feature of most neurodegenerative diseases, including Huntington’s disease. Huntington’s disease is caused by expansion of a polyglutamine tract in the huntingtin protein; mutant huntingtin protein (mHtt) is unstable and accumulates in large intracellular inclusions both in affected individuals and when expressed in eukaryotic cells. Using mHtt-GFP expressed in Saccharomyces cerevisiae, we find that mHtt-GFP inclusions are dynamic, mobile, gel-like structures that concentrate mHtt together with the disaggregase Hsp104. Although inclusions may associate with the vacuolar membrane, the association is reversible and we find that inclusions of mHtt in S. cerevisiae are not taken …

Frontal Alpha Asymmetry And Inhibitory Control Among Individuals With Cannabis Use Disorders, Alina Shevorykin, Lesia M. Ruglass, Robert D. Melara

Publications and Research

To better understand the biopsychosocial mechanisms associated with development and maintenance of cannabis use disorder (CUD), we examined frontal alpha asymmetry (FAA) as a measure of approach bias and inhibitory control in cannabis users versus healthy nonusers. We investigated: (1) whether FAA could distinguish cannabis users from healthy controls; (2) whether there are cue-specific FAA effects in cannabis users versus controls; and (3) the time course of cue-specific approach motivation and inhibitory control processes. EEG data were analyzed from forty participants (CUD (n = 20) and controls (n = 20)) who completed a modified visual attention task. Results showed controls …

Activation Of Lxrβ Inhibits Tumor Respiration And Is Synthetically Lethal With Bcl-Xl Inhibition, Trang Thi Thu Nguyen, Chiaki Tsuge Ishida, Enyuan Shang, Chang Shu, Consuelo Torrini, Yiru Zhang, Elena Bianchetti, Maria J. Sanchez-Quintero, Giulio Kleiner, Catarina M. Quinzii, Mike-Andrew Westhoff, Georg Karpel-Massler, Peter Canoll, Markus D. Siegelin

Publications and Research

Liver-X-receptor (LXR) agonists are known to bear anti-tumor activity. However, their efficacy is limited and additional insights regarding the underlying mechanism are necessary. By performing transcriptome analysis coupled with global polar metabolite screening, we show that LXR agonists, LXR623 and GW3965, enhance synergistically the anti-proliferative effect of BH3 mimetics in solid tumor malignancies, which is predominantly mediated by cell death with features of apoptosis and is rescued by exogenous cholesterol. Extracellular flux analysis and carbon tracing experiments (U-¹³C-glucose and U-¹³C-glutamine) reveal that within 5 h, activation of LXRβ results in reprogramming of tumor cell metabolism, leading …

Modeling Interval Timing By Recurrent Neural Nets, Theodore Raphan, Eugene Dorokhin, Andrew R. Delamater

Publications and Research

The purpose of this study was to take a new approach in showing how the central nervous system might encode time at the supra-second level using recurrent neural nets (RNNs). This approach utilizes units with a delayed feedback, whose feedback weight determines the temporal properties of specific neurons in the network architecture. When these feedback neurons are coupled, they form a multilayered dynamical system that can be used to model temporal responses to steps of input in multidimensional systems. The timing network was implemented using separate recurrent “Go” and “NoGo” neural processing units to process an individual stimulus indicating the …

Endothelial Iqgap1 Regulates Leukocyte Transmigration By Directing The Lbrc To The Site Of Diapedesis, David P. Sullivan, Prarthana J. Dalal, Fanny Jaulin, David B. Sacks, Geri Kreitzer, William A. Muller

Publications and Research

Transendothelial migration (TEM) of leukocytes across the endothelium is critical for inflammation. In the endothelium, TEM requires the coordination of membrane movements and cytoskeletal interactions, including, prominently, recruitment of the lateral border recycling compartment (LBRC). The scaffold protein IQGAP1 was recently identified in a screen for LBRC-interacting proteins. Knockdown of endothelial IQGAP1 disrupted the directed movement of the LBRC and substantially reduced leukocyte TEM. Expression of truncated IQGAP1 constructs demonstrated that the calponin homology domain is required for IQGAP1 localization to endothelial borders and that the IQ domain, on the same IQGAP1 polypeptide, is required for its function in TEM. …

Choline: Exploring The Growing Science On Its Benefits For Moms And Babies, Hunter W. Korsmo, Xinyin Jiang, Marie A. Caudill

Publications and Research

The importance of ensuring adequate choline intakes during pregnancy is increasingly recognized. Choline is critical for a number of physiological processes during the prenatal period with roles in membrane biosynthesis and tissue expansion, neurotransmission and brain development, and methyl group donation and gene expression. Studies in animals and humans have shown that supplementing the maternal diet with additional choline improves several pregnancy outcomes and protects against certain neural and metabolic insults. Most pregnant women in the U.S. are not achieving choline intake recommendations of 450 mg/day and would likely benefit from boosting their choline intakes through dietary and/or supplemental approaches.

Intervention Principles In Pediatric Health Care: The Difference Between Physicians And The State., D. Robert Macdougall

Publications and Research

According to various accounts, intervention in pediatric decisions is justified either by the best interests standard or by the harm principle. While these principles have various nuances that distinguish them from each other, they are similar in the sense that both focus primarily on the features of parental decisions that justify intervention, rather than on the competency or authority of the parties that intervene. Accounts of these principles effectively suggest that intervention in pediatric decision making is warranted for both physicians and the state under precisely the same circumstances. This essay argues that there are substantial differences in the competencies …

Cc Chemokine Ccl1 Receptor Ccr8 Mediates Conversion Of Mesenchymal Stem Cells To Embryoid Bodies Expressing Foxp3+Ccr8+ Regulatory T Cells, Nasreen Haque, Tuteja Akaash, Niloufar Haque

Publications and Research

Embryoid bodies (EBs) are three dimensional aggregates of pluripotent stem cells primarily used to investigate morphogenesis and cell toxicity, are also attractive tools in regenerative medicine. While embryonic stem cells (ESCs) and induced pluripotent cells (IPSCs) have been shown to form EBs in mouse, primate and humans, EB formation have not been previously demonstrated in mesenchymal stem cells (MSCs). Here we show that rat MSCs form EBs; which express regulatory T cell (Treg) marker Foxp3 and CC chemokine CCL1 receptor CCR8. We show a novel method for formation of EBs from MSCs under stress and demonstrate that the induction of …

Developing Physician Educational Competencies For The Management Of Female Genital Cutting: A Call To Action, Holly G. Atkinson, Amaris Geisler

Publications and Research

Female genital cutting (FGC), also called female genital mutilation, is defined as “all procedures involving partial or total removal of the external female genitalia or other injury to the female genital organs whether for cultural, religious, or other nontherapeutic reasons.” FGC can have significant health consequences, including multiple physical and psychological complications, throughout the life course. Despite violating numerous human rights and existing legal prohibitions, the practice continues. In the United States, FGC is becoming increasingly prevalent, however, physicians are not routinely trained to care for these patients. Despite the evidence of the need, there is a woeful lack of …

Preparing Physicians To Contend With The Problem Of Dual Loyalty, Holly G. Atkinson

Publications and Research

Dual loyalty is defined as, particularly as it pertains to the field of medicine, a conflict or potential conflict between a healthcare professional’s simul- taneous obligations–expressed or implied–to a patient and to a third party. Dual loyalty situations often compromise physicians’ ethical behavior, lead- ing them to participate, either knowingly or unknowingly, in human rights violations perpetrated by a third party, often the state. Classic dual loyalty situations include the participation of physicians in state-sanctioned torture or the death penalty. However, there are a number of other dual loyalty scenarios that arise routinely in clinical practice in both closed institutions …
