Background

Venous Thrombo-embolism (VTE – Deep venous thrombosis (DVT) and/or pulmonary embolism (PE) – in traumatized patients causes significant morbidity and mortality. The current study evaluates the effectiveness of DVT surveillance in reducing PE, and performs a cost-effectiveness analysis.

Methods

All traumatized patients admitted to the adult ICU underwent twice weekly DVT surveillance by bilateral lower extremity venous Duplex examination (48-month surveillance period – SP). The rates of DVT and PE were recorded and compared to the rates observed in the 36-month pre-surveillance period (PSP). All patients in both periods received mechanical and pharmacologic prophylaxis unless contraindicated. Total costs – …

Job Attributes, Job Satisfaction And The Return To Health After Breast Cancer Diagnosis And Treatment, Andrew J. Barnes, Nicholas Robert, Cathy J. Bradley

Health Behavior and Policy Publications

Background: As detection and treatment of cancer has advanced, the number of working age women with breast cancer has increased. This study provides new information on the intersection of breast cancer treatment and job tasks and how, together, they impact employed and newly diagnosed women.

Methods: The sample comprised 493 employed women within two months of initiating treatment. Job satisfaction and demands were assessed by pre-diagnosis recall along with measures of mental and physical health and assessed again nine months after initiating treatment. Using seemingly unrelated regression, we tested the effect of job tasks and satisfaction on mental and …

Health Behavior and Policy Publications

Objective

To investigate the determinants and quality of coverage decisions among uninsured choosing plans in a hypothetical health insurance marketplace.

Study Setting

Two samples of uninsured individuals: one from an Internet-based sample comprised largely of young, healthy, tech-savvy individuals (n = 276), and the other from low-income, rural Virginians (n = 161).

Study Design

We assessed whether health insurance comprehension, numeracy, choice consistency, and the number of plan choices were associated with participants' ability to choose a cost-minimizing plan, given their expected health care needs (defined as choosing a plan costing no more than $500 in excess of the total …

Childhood Sexual Abuse And The Development Of Recurrent Major Depression In Chinese Women, Jing Chen, Yiyun Cai, Enzhao Cong, Ying Liu, Jingfang Gao, Youhui Li, Ming Tao, Kerang Zhang, Xumei Wang, Chengge Gao, Lijun Yang, Kan Li, Jianguo Shi, Gang Wang, Lanfen Liu, Jinbei Zhang, Bo Du, Guoqing Jiang, Jianhua Shen, Zhen Zhang, Wei Liang, Jing Sun, Jian Hu, Tiebang Liu, Xueyi Wang, Guodong Miao, Huaqing Meng, Yi Li, Guoping Huang, Gongying Li, Baowei Ha, Hong Deng, Qiyi Mei, Hui Zhong, Shugui Gao, Hong Sang, Yutang Zhang, Xiang Fang, Fengyu Yu, Donglin Yang, Tieqiao Liu, Yunchun Chen, Xiaohong Hong, Danhua Gu, Xiaoping Wang, Xiaojuan Liu, Qiwen Zhang, Yihan Li, Yiping Chen, Kenneth S. Kendler, Shenxun Shi, Jonathan Flint

Psychiatry Publications

Background

Our prior study in Han Chinese women has shown that women with a history of childhood sexual abuse (CSA) are at increased risk for developing major depression (MD). Would this relationship be found in our whole data set?

Method

Three levels of CSA (non-genital, genital, and intercourse) were assessed by self-report in two groups of Han Chinese women: 6017 clinically ascertained with recurrent MD and 5983 matched controls. Diagnostic and other risk factor information was assessed at personal interview. Odds ratios (ORs) were calculated by logistic regression.

Results

We confirmed earlier results by replicating prior analyses in 3,950 new …

Genome-Wide And Gene-Based Association Studies Of Anxiety Disorders In European And African American Samples, Takeshi Otowa, Brion S. Maher, Steven H. Aggen, Joseph L. Mcclay, Edwin J. Van Den Oord, John M. Hettema

Psychiatry Publications

Anxiety disorders (ADs) are common mental disorders caused by a combination of genetic and environmental factors. Since ADs are highly comorbid with each other, partially due to shared genetic basis, studying AD phenotypes in a coordinated manner may be a powerful strategy for identifying potential genetic loci for ADs. To detect these loci, we performed genome-wide association studies (GWAS) of ADs. In addition, as a complementary approach to single-locus analysis, we also conducted gene- and pathway-based analyses. GWAS data were derived from the control sample of the Molecular Genetics of Schizophrenia (MGS) project (2,540 European American and 849 African American …

The Omega-3 Fatty Acid Eicosapentaenoic Acid Is Required For Normal Alcohol Response Behaviors In C. Elegans, Richard C. Raabe, Laura D. Mathies, Andrew G. Davies, Jill C. Bettinger

Pharmacology and Toxicology Publications

Alcohol addiction is a widespread societal problem, for which there are few treatments. There are significant genetic and environmental influences on abuse liability, and understanding these factors will be important for the identification of susceptible individuals and the development of effective pharmacotherapies. In humans, the level of response to alcohol is strongly predictive of subsequent alcohol abuse. Level of response is a combination of counteracting responses to alcohol, the level of sensitivity to the drug and the degree to which tolerance develops during the drug exposure, called acute functional tolerance. We use the simple and well-characterized nervous system of Caenorhabditis …

Specific Localization Of Β-Arrestin2 In Myenteric Plexus Of Mouse Gastrointestinal Tract, Hercules T. Maguma, Dipanjana D. De, Sukhada Bhave, William L. Dewey, Hamid I. Akbarali

Pharmacology and Toxicology Publications

Abstract

β-arrestin2 is a key molecule involved in signaling and internalization of activated G protein-coupled receptors including µ-opioid receptors (MOR). Previously we have shown that decreased expression of β-arrestin2 upon chronic morphine is associated with the development of opioid tolerance in the gastrointestinal tract. However, the localization of β-arrestin2 within the gastrointestinal wall is not known. In this study we found that β-arrestin2 is localized in the soma of a select group of neurons in the myenteric ganglia but not in smooth muscle. The density of β-arestin2 was significantly higher in the ileum than the colon. We identified four variants …

Activation Of Nlrp3 Inflammasomes Enhances Macrophage Lipid-Deposition And Migration: Implication Of A Novel Role Of Inflammasome In Atherogenesis, Xiang Li, Yang Zhang, Min Xia, Erich Gulbins, Krishna M. Boini, Pin-Lan Li

Pharmacology and Toxicology Publications

Although Nlrp3 inflammasome activation in macrophages has been shown to be critical for the development of atherosclerosis upon atherogenic stimuli, it remains unknown whether activated Nlrp3 inflammasomes by other non-atherogenic stimuli induce alterations in macrophages that may contribute in the concert with other factors to atherogenesis. Thus, the present study tested the hypothesis that activation of Nlrp3 inflammasomes by ATP, which is a classical non-lipid danger stimulus, enhances the migration of macrophage and increases lipids deposition in macrophages accelerating foam cell formation. We first demonstrated that extracellular ATP (2.5 mM) markedly increased the formation and activation of Nlrp3 inflammasomes in …

Toward A Robust Computational Screening Strategy For Identifying Glycosaminoglycan Sequences That Display High Specificity For Target Proteins, Nehru Viji Sankaranarayanan, Umesh R. Desai

Medicinal Chemistry Publications

Glycosaminoglycans (GAGs) interact with many proteins to regulate processes such as hemostasis, cell adhesion, growth and differentiation and viral infection. Yet, majority of these interactions remain poorly understood at a molecular level. A major reason for this state is the phenomenal structural diversity of GAGs, which has precluded analysis of specificity of their interactions. We had earlier presented a computational protocol for predicting “high-specificity” GAG sequences based on combinatorial virtual library screening (CVLS) technology. In this work, we expand the robustness of this technology through rigorous studies of parameters affecting GAG recognition of proteins, especially antithrombin and thrombin. The CVLS …

Test Of Ideational Praxis (Tip): Preliminary Findings And Interrater And Test–Retest Reliability With Preschoolers, Shelly J. Lane, Carol K. Ivey, Teresa A. May-Benson

Occupational Therapy Publications

Praxis is the ability of the brain to develop an idea for action and plan, organize, and execute unfamiliar motor actions. It enables purposeful interaction with people and things in the environment. Ideation is central to praxis but has been little researched. This study investigated the reliability of the Test of Ideational Praxis (TIP) and examined ideational praxis in typical preschoolers. TIP performance for 78 preschoolers ages 3, 4, and 5 yr was videotaped and scored by two trained raters. The TIP has strong interrater reliability, supporting earlier findings. Further, we documented test–retest stability over 2 wk. As a group, …

Kendler, Xumei Wang, Youhui Li, Jonathan Flint

Psychiatry Publications

Objective

To investigate the risk factors that contribute to smoking in female patients with major depressive disorder (MDD) and the clinical features in depressed smokers.

Methods

We examined the smoking status and clinical features in 6120 Han Chinese women with MDD (DSM-IV) between 30 and 60 years of age across China. Logistic regression was used to determine the association between clinical features of MDD and smoking status and between risk factors for MDD and smoking status.

Results

Among the recurrent MDD patients there were 216(3.6%) current smokers, 117 (2.0%) former smokers and 333(5.6%) lifetime smokers. Lifetime smokers had a slightly …

Associations Of Educational Attainment, Occupation, Social Class And Major Depressive Disorder Among Han Chinese Women, Jianguo Shi, Yan Zhang, Feihu Liu, Yajuan Li, Junhui Wang, Jonathan Flint, Jingfang Gao, Youhui Li, Ming Tao, Kerang Zhang, Xumei Wang, Chengge Gao, Lijun Yang, Kan Li, Shenxun Shi, Gang Wang, Lanfen Liu, Jinbei Zhang, Bo Du, Guoqing Jiang, Jianhua Shen, Zhen Zhang, Wei Liang, Jing Sun, Jian Hu, Tiebang Liu, Xueyi Wang, Guodong Miao, Huaqing Meng, Yi Li, Chunmei Hu, Yi Li, Guoping Huang, Gongying Li, Baowei Ha, Hong Deng, Qiyi Mei, Hui Zhong, Shugui Gao, Hong Sang, Yutang Zhang, Xiang Fang, Fengyu Yu, Donglin Yang, Tieqiao Liu, Yunchun Chen, Xiaohong Hong, Wenyuan Wu, Guibing Chen, Min Cai, Yan Song, Jiyang Pan, Jicheng Dong, Runde Pan, Wei Zhang, Zhenming Shen, Zhengrong Liu, Danhua Gu, Xiaoping Wang, Xiaojuan Liu, Qiwen Zhang, Yihan Li, Yiping Chen, Kenneth S. Kendler

Psychiatry Publications

Background

The prevalence of major depressive disorder (MDD) is higher in those with low levels of educational attainment, the unemployed and those with low social status. However the extent to which these factors cause MDD is unclear. Most of the available data comes from studies in developed countries, and these findings may not extrapolate to developing countries. Examining the relationship between MDD and socio economic status in China is likely to add to the debate because of the radical economic and social changes occurring in China over the last 30 years.

Principal findings

We report results from 3,639 Chinese women …

Headaches And Hemiparesis In An Immunocompetent Inmate, Andrea Gilbert Jelinek, Christine Fuller, Ahmet Baykal, Kimberly Stogner-Underwood, Hope Richard, Knarik Arkun

Pathology Publications

This is a case of a 22 year-old African American male inmate with no significant past medical history who regularly cleaned moldy bathrooms and showers during his incarceration. The patient presented with progressive development of left-sided weakness, dizziness, headaches, and vomiting over a two month period. In summary, we report this case to boost awareness of the potential for CNS phaeohyphomycosis infection to present as a clinical and radioimaging mimic of high grade glioma. Our patient, a previously healthy adult, is one of less than a dozen cases of cerebral phaeohyphomycosis due to Bipolaris documented in the literature, and is …

The Status Of The Scholarship Of Teaching And Learning In Dental Education, Sharon K. Lanning, Michelle Mcgregor, Geralyn Crain, Christopher J. Van Ness, Nancy T. Keselyak, John W. Killip

Periodontics Publications

The purpose of this study was to determine the current status of the Scholarship of Teaching and Learning (SoTL) within academic dentistry. A twenty-two-item survey was distributed to faculty members of American Dental Education Association (ADEA) member schools asking about their awareness of SoTL practices, perceived barriers to SoTL application, and ways to enhance SoTL activity. Four hundred thirty surveys with equal distribution of assistant, associate, and full professors were received (this may be considered a response rate of 5.4 percent out of roughly 8,000 ADEA faculty members). Almost 70 percent of the respondents indicated that they highly valued SoTL; …

Development Of Status Epilepticus, Sustained Calcium Elevations And Neuronal Injury In A Rat Survival Model Of Lethal Paraoxon Intoxication, Laxmikant Sudhir Deshpande, Dawn S. Carter, Kristin Phillips, Robert E. Blair, Robert J. Delorenzo

Neurology Publications

Paraoxon (POX) is an active metabolite of organophosphate (OP) pesticide parathion that has been weaponized and used against civilian populations. Exposure to POX produces high mortality. OP poisoning is often associated with chronic neurological disorders. In this study, we optimize a rat survival model of lethal POX exposures in order to mimic both acute and long-term effects of POX intoxication. Male Sprague–Dawley rats injected with POX (4 mg/kg, ice-cold PBS, s.c.) produced a rapid cholinergic crisis that evolved into status epilepticus (SE) and death within 6–8 min. The EEG profile for POX induced SE was characterized and showed clinical and …

Chronic Behavioral And Cognitive Deficits In A Rat Survival Model Of Paraoxon Toxicity, Laxmikant Sudhir Deshpande, Kristin Phillips, Beverly Huang, Robert J. Delorenzo

Neurology Publications

Organophosphate (OP) compounds, including paraoxon (POX), are similar to nerve agents such as sarin. There is a growing concern that OP agents could be weaponized to cause mass civilian causalities. We have developed a rodent survival model of POX toxicity that is being used to evaluate chronic morbidity and to screen for medical countermeasures against severe OP exposure. It is well known that the survivors of nerve gas and chronic OP exposure exhibit neurobehavioral deficits such as mood changes, depression, and memory impairments. In this study we investigated whether animals surviving severe POX exposure exhibited long-term neurological impairments. POX exposure …

Virtual Villages For Aging In Place, Edward F. Ansello

Director's Editorials from Age in Action

The Village concept, first implemented by Beacon Hill Village in Boston, has gained much attention as a model for aging in place. Villages are community-based, self-governing, not for profit organizations whose members pay an annual fee, from several hundred dollars to a thousand or more, to obtain access to an array of services that may assist them to maintain their physical health, keep up their property, manage their resources, continue to grow intellectually and engage socially while remaining part of the community in their homes. At a dozen years in, the Village concept has demonstrated its worth. It seems to …

Morphine Enhances Hiv-1sf162-Mediated Neuron Death And Delays Recovery Of Injured Neurites, Ruturaj R. Masvekar, Nazira El-Hage, Kurt F. Hauser, Pamela E. Knapp

Anatomy and Neurobiology Publications

HIV-1 enters the CNS soon after initial systemic infection; within the CNS parenchyma infected and/or activated perivascular macrophages, microglia and astrocytes release viral and cellular toxins that drive secondary toxicity in neurons and other cell types. Our previous work has largely modeled HIV-neuropathology using the individual viral proteins Tat or gp120, with murine striatal neurons as targets. To model disease processes more closely, the current study uses supernatant from HIV-1-infected cells. Supernatant from HIV-1SF162-infected differentiated-U937 cells (HIV+sup) was collected and p24 level was measured by ELISA to assess the infection. Injection drug abuse is a significant risk factor for HIV-infection, …

Memo Has A Novel Role In S1p Signaling And Crucial For Vascular Development, Shunya Kondo, Alessia Bottos, Jeremy Allegood, Regis Masson, Francisca G. Maurer, Christel Genoud, Patrick Kaeser, Andrea Huwiler, Masato Murakami, Sarah Spiegel, Nancy E. Hynes

Biochemistry and Molecular Biology Publications

Memo is a conserved protein that was identified as an essential mediator of tumor cell motility induced by receptor tyrosine kinase activation. Here we show that Memo null mouse embryonic fibroblasts (MEFs) are impaired in PDGF-induced migration and this is due to a defect in sphingosine-1-phosphate (S1P) signaling. S1P is a bioactive phospholipid produced in response to multiple stimuli, which regulates many cellular processes. S1P is secreted to the extracellular milieu where it exerts its function by binding a family of G-protein coupled receptors (S1PRs), causing their activation in an autocrine or paracrine manner. The process, termed cell-autonomous S1PR signaling, …

Otitis Media In Sperm-Associated Antigen 6 (Spag6)-Deficient Mice, Xiaofei Li, Lei Xu, Jianfeng Li, Boqin Li, Xiaohui Bai, Jerome F. Strauss Iii, Zhibing Zhang, Haibo Wang

Biochemistry and Molecular Biology Publications

Mammalian SPAG6 protein is localized to the axoneme central apparatus, and it is required for normal flagella and cilia motility. Recent studies demonstrated that the protein also regulates ciliogenesis and cilia polarity in the epithelial cells of brain ventricles and trachea. Motile cilia are also present in the epithelial cells of the middle ear and Eustachian tubes, where the ciliary system participates in the movement of serous fluid and mucus in the middle ear. Cilia defects are associated with otitis media (OM), presumably due to an inability to efficiently transport fluid, mucus and particles including microorganisms. We investigated the potential …

Is The Consistency More Important Than The Ingredients For Treatment? Case Report For Eosinophilic Esophagitis, Dan W. Parrish, Shashank Sharma, Santhosh Kumar

Surgery Publications

Eosinophilic Esophagitis seems to be an ever-changing disease, from patient-to-patient and from year-to-year in the same patient. Improvements in these patients’ lives have been made with the realization that elimination of dietary antigens helped with symptom relief and treatment with topical steroids assisted in eradication of esophageal eosinophils.

This case study has two very important aspects that should be emphasized. The first is the realization that it may be consistency of the steroid mixture rather than the ingredients that infer the effectiveness of the EoE treatment, and the second aspect is the willingness of the medical team to listen to …

Metabolic Effects Of Acute Thiamine Depletion Are Reversed By Rapamycin In Breast And Leukemia Cells, Shuqian Liu, Sumitra Miriyala, Mignon A. Keaton, Craig T. Jordan, Christina Wiedl, Daret K. St. Clair, Jeffrey A. Moscow

Pediatrics Publications

Thiamine-dependent enzymes (TDEs) control metabolic pathways that are frequently altered in cancer and therefore present cancer-relevant targets. We have previously shown that the recombinant enzyme thiaminase cleaves and depletes intracellular thiamine, has growth inhibitory activity against leukemia and breast cancer cell lines, and that its growth inhibitory effects were reversed in leukemia cell lines by rapamycin. Now, we first show further evidence of thiaminase therapeutic potential by demonstrating its activity against breast and leukemia xenografts, and against a primary leukemia xenograft. We therefore further explored the metabolic effects of thiaminase in combination with rapamycin in leukemia and breast cell lines. …

Comprehensive Analysis Of Human Cytomegalovirus Microrna Expression During Lytic And Quiescent Infection, Zhang-Zhou Shen, Xing Pan, Ling-Feng Miao, Han-Qing Ye, Stéphane Chavanas, Christian Davrinche, Michael Mcvoy, Min-Hua Luo

Pediatrics Publications

Background

Human cytomegalovirus (HCMV) encodes microRNAs (miRNAs) that function as post-transcriptional regulators of gene expression during lytic infection in permissive cells. Some miRNAs have been shown to suppress virus replication, which could help HCMV to establish or maintain latent infection. However, HCMV miRNA expression has not been comprehensively examined and compared using cell culture systems representing permissive (lytic) and semi-permissive vs. non-permissive (latent-like) infection.

Methods

Viral miRNAs levels and expression kinetics during HCMV infection were determined by miRNA-specific stem-loop RT-PCR. HCMV infected THP-1 (non-permissive), differentiated THP-1 (d-THP-1, semi-permissive) and human embryo lung fibroblasts (HELs, fully-permissive) were examined. The impact of …

Clinical Features And Genetic Analysis Of 20 Chinese Patients With X-Linked Hyper-Igm Syndrome, Lin-Lin Wang, Wei Zhou, Wei Zhao, Zhi-Qing Tian, Wei-Fan Wang, Xiao-Fang Wang, Tong-Xin Chen

Pediatrics Publications

X-linked hyper-IgM syndrome (XHIGM) is one type of primary immunodeficiency diseases, resulting from defects in the CD40 ligand/CD40 signaling pathways. We retrospectively analyzed the clinical and molecular features of 20 Chinese patients diagnosed and followed up in hospitals affiliated to Shanghai Jiao Tong University School of Medicine from 1999 to 2013. The median onset age of these patients was 8.5 months (range: 20 days–21 months). Half of them had positive family histories, with a shorter diagnosis lag. The most common symptoms were recurrent sinopulmonary infections (18 patients, 90%), neutropenia (14 patients, 70%), oral ulcer (13 patients, 65%), and protracted diarrhea …

Contrasting Influences Of Drosophila White/Mini-White On Ethanol Sensitivity In Two Different Behavioral Assays, Robin F. Chan, Carol Atkinson Lewellyn, Jacqueline M. Deloyht, Kristyn Sennett, Scarlett Coffman, Matthew Hewitt, Jill C. Bettinger, John M. Warrick, Mike Grotewiel

Human and Molecular Genetics Publications

Background

The fruit fly Drosophila melanogaster has been used extensively to investigate genetic mechanisms of ethanol-related behaviors. Many past studies in flies, including studies from our laboratory, have manipulated gene expression using transposons carrying the genetic-phenotypic marker mini-white, a derivative of the endogenous gene white. Whether the mini-white transgenic marker or the endogenous white gene influence behavioral responses to acute ethanol exposure in flies has not been systematically investigated.

Methods

We manipulated mini-white and white expression via (i) transposons marked with mini-white, (ii) RNAi against mini-white and white and (iii) a null allele of white. We assessed ethanol sensitivity and …

Barriers And Disparities In Emergency Medical Services 911 Calls For Stroke Symptoms In The United States Adult Population: 2009 Brfss Survey, Munseok Seo, Charles Begley, James R. Langabeer, Jami L. Dellifraine

Health Administration Publications

Introduction: This study examines barriers and disparities in the intentions of American citizens, when dealing with stroke symptoms, to call 911. This study hypothesizes that low socioeconomic populations are less likely to call 911 in response to stroke recognition. Methods: The study is a cross-sectional design analyzing data from the Centers for Disease Control’s 2009 Behavioral Risk Factor Surveillance Survey, collected through a telephone-based survey from 18 states and the District of Columbia. The study identified the 5 most evident stroke-warning symptoms based on those given by the American Stroke Association. We conducted appropriate weighting procedures to account for the …

Regional Medical Campuses: A New Classification System, Cheifetz E. Craig, Mcowen S. Katherine, Gagne Pierre, Wong L. Jennifer

Inova Campus Publications

There is burgeoning belief that regional medical campuses (RMCs) are a significant part of the narrative about medical education and the health care workforce in the United States and Canada. Although RMCs are not new, in the recent years of medical education enrollment expansion, they have seen their numbers increase. Class expansion explains the rapid growth of RMCs in the past 10 years, but it does not adequately describe their function. Often, RMCs have missions that differ from their main campus, especially in the areas of rural and community medicine. The absence of an easy-to-use classification system has led to …

Delayed Repair Of Myelomeningoceles, Joseph C. Watson, Gary Tye, John D. Ward

Neurosurgery Publications

Objective: Myelomeningocele is a defect that is typically surgically repaired within the first few days of life in developed countries to minimize the risk of meningitis. If left unrepaired, these children may survive to have their meningocele sac epithelialize. The surgical reduction and closure of an epithelialized myelomeningocele represents a unique challenge for the neurosurgeon, as it requires a modification of the typical closure technique.

Methods: 10 years experience in 97 patients with the delayed (>6 months) repair of myelomeningoceles was the basis of this report. Results: Repair technique in a child with a myelomeningocele that was not repaired …

Obstetrics and Gynecology Publications

Currently very little is known about the differential expression and function of the transcription factor SOX5 during B cell maturation. We identified two new splice variants of SOX5 in human B cells, encoding the known L-SOX5B isoform and a new shorter isoform L-SOX5F. The SOX5transcripts are highly expressed during late stages of B-cell differentiation, including atypical memory B cells, activated CD21low B cells and germinal center B cells of tonsils. In tonsillar sections SOX5 expression was predominantly polarized to centrocytes within the light zone. After in vitro stimulation, SOX5 expression was down-regulated during proliferation while high expression levels were …
