Does Economic Development Contribute To Sex Differences In Ischaemic Heart Disease Mortality? Hong Kong As A Natural Experiment Using A Case-Control Study, Mary Schooling, Tai Hing Lam, Sai Yin Ho, Kwok Hang Mak, Gabriel M. Leung

Publications and Research

Background
The male excess risk of premature ischemic heart disease (IHD) mortality may be partially due to an unknown macro-environmental influence associated with economic development. We examined whether excess male risk of IHD mortality was higher with birth in an economically developed environment.

Methods
We used multivariable logistic regression in a population-based case-control study of all adult deaths in Hong Kong Chinese in 1998 to compare sex differences in IHD mortality (1,189 deaths in men, 1,035 deaths in women and 20,842 controls) between Hong Kong residents born in economically developed Hong Kong or in contemporaneously undeveloped Guangdong province in China. …

Nitrated Alpha-Synuclein Immunity Accelerates Degeneration Of Nigral Dopaminergic Neurons., Eric J. Benner, Rebecca Banerjee, Ashley D. Reynolds, Simon Sherman, Vladimir M. Pisarev, Vladislav Tsiperson, Craig Nemachek, Pawel Ciborowski, Serge Przedborski, R. Lee Mosley, Howard Gendelman

Journal Articles: Eppley Institute

BACKGROUND: The neuropathology of Parkinson's disease (PD) includes loss of dopaminergic neurons in the substantia nigra, nitrated alpha-synuclein (N-alpha-Syn) enriched intraneuronal inclusions or Lewy bodies and neuroinflammation. While the contribution of innate microglial inflammatory activities to disease are known, evidence for how adaptive immune mechanisms may affect the course of PD remains obscure. We reasoned that PD-associated oxidative protein modifications create novel antigenic epitopes capable of peripheral adaptive T cell responses that could affect nigrostriatal degeneration.

METHODS AND FINDINGS: Nitrotyrosine (NT)-modified alpha-Syn was detected readily in cervical lymph nodes (CLN) from 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) intoxicated mice. Antigen-presenting cells within the CLN …

Evaluation Of The Efficacy Of Chloroplast-Derived Antigensagainst Malaria, Melissa Schreiber

Electronic Theses and Dissertations

Malaria is the most prevalent vector-borne parasitic disease worldwide and a major cause of death from infections. There is a great need to develop a low cost vaccine for malaria to control transmission of infection and impact of disease, due to the emergence of anti-malarial resistance. Two leading blood stage malarial vaccine candidates are the apical membrane antigen-1 (AMA-1) and the merozoite surface protein-1 (MSP-1). The aim of this project is to express malarial antigens in tobacco plants via plastid transformation and deliver them by subcutaneous or oral gavage of minimally processed transplastomic tissue to evaluate their efficacy to elicit …

Methods For Detection Of Matrix Metalloproteinases As Biomarkers In Cardiovascular Disease, Viorica Lopez-Avila, Juliet Spencer

Biology Faculty Publications

Matrix metalloproteinases (MMPs) are a family of zinc-dependent proteolytic enzymes that degrade extracellular matrix (ECM) components like collagen, fibronectin, and laminin. While this activity is important for normal development, morphogenesis, and wound healing, deregulation of MMP activity has been implicated in a number of cardiovascular diseases, including congenital heart defects, atherosclerosis, myocardial infarction, and congestive heart failure. MMPs are good potential diagnostic indicators of cardiovascular disease, but current detection methods are time consuming and quite laborious. This review will discuss MMP biology, current methods for detection of MMPs from patient samples, and potential new developments in multiplexed analysis of MMPs.

Results From A Multicenter Trial Of Academic Hospitalists, John A. Schneider, Qi Zhang, Andrew Auerbach, David Gonzales, Peter Kaboli, Jeffrey Schnipper, Tosha B. Wetterneck, David L. Pitrak, David O. Meltzer

Community & Environmental Health Faculty Publications

Background. Little is known about the effect of provider type and experience on outcomes, resource use, and processes of care of hospitalized patients with human immunodeficiency virus (HIV) infection. Hospitalists are caring for this population with increasing frequency.

Methods. Data from a natural experiment in which patients were assigned to physicians on the basis of call cycle was used to study the effects of provider type—that is, hospitalist versus non hospitalist—and HIV-specific inpatient experience on resource use, outcomes, and selected measures of processes of care at 6 academic institutions. Administrative data, inpatient interviews, 30-day follow-up interviews, and the National Death …

Association Of Epstein-Barr Virus With Nasopharyngeal Carcinoma And Current Status Of Development Of Cancer-Derived Cell Lines, Charles A. Gullo Phd, Wong Kein Low, Gerrard Teoh

Biochemistry and Microbiology

It is well known that the Epstein-Barr virus (EBV) contributes directly to tumourigenesis in nasopharyngeal carcinoma (NPC), primarily in the undifferentiated form of NPC (WHO type III; UNPC or UC), which is commonly found in South East Asia. Unfortunately, research in NPC has been severely hampered by the lack of authentic EBV-positive (EBV+) human NPC cell lines for study. Since 1975, there have been more than 20 reported NPC cell lines. However, many of these NPC-derived cell lines do not express EBV transcripts in long-term culture, and therefore that finding may dispute the fundamental theory of NPC carcinogenesis. In fact, …

Aboriginal Policy Research Consortium International (APRCi)

Objectives: Vulnerability to HIV and Hepatitis C virus (HCV) infection for indigenous populations worldwide must be contextualized in experiences of current and past trauma. Aboriginal women entrenched in poverty face further gender-specific harms which place them at increased risk for HIV infection.

Methods: This study was cross-sectional and based on a community-based sample of Aboriginal young people (Métis, Abo- riginal, First Nations, Inuit, and non-status Indians) between the ages of 14 and 30 years who used injection or non-injection non- cannabis illegal drugs (street drugs) in the previous month. Between October 2003 and July 2005, 543 participants living in either …

Ilario, Paulo Reis, Regina C.S. Salles, Suzanne Westman, Juan Diaz

HIV and AIDS

The Population Council, in collaboration with the Brazil Ministry of Health, the Municipal Program of STD/AIDS of Campinas, and the US Centers for Disease Control and Prevention/Global AIDS Program/Brazil, conducted a study to characterize the sociodemographic, behavioral, and environmental factors associated with subgroups of MSM who are most at risk for HIV infection. This research is the first Brazilian study to provide population-based estimates for HIV, syphilis, and HIV-related risk behaviors using an innovative sampling technique to reach members of the target population. Our data suggest the importance for HIV prevention programs to address not only sexual risk reduction, but …

Is It Feasible To Integrate Alcohol-Related Risk Reduction Counseling Into Vct Services? Findings From Kenya, Caroline Mackenzie, Karusa Kiragu, George Odingo, Rukia Yassin, Peter Shikuku, Patrick Angala, Nduku Kilonzo, William Sinkele, Melania Akinyi

HIV and AIDS

In Kenya, an estimated 30 percent of men report to be alcohol users which may be fueling the HIV pandemic, due to its association with high-risk sexual behavior and reduced inhibitions. The Population Council’s Horizons program collaborated on a study to improve screening of clients for alcohol use, provision of feedback of screening results, and referrals to care and support during voluntary testing and counseling (VCT) for HIV. Overall, the results indicate that it is feasible to integrate alcohol risk reduction counseling into VCT, and that it is generally accepted by providers and clients alike. This study therefore supports the …

Caring For Caregivers: An Hiv/Aids Workplace Intervention For Hospital Staff In Zambia—Evaluation Results, Karusa Kiragu, Mutinta Nyumbu, Thabale J. Ngulube, Panganani Njobvu, Chilufya Mwaba, Arthur Kalimbwe, Spike Bradford

HIV and AIDS

The Horizons Program collaborated on a Caring for Caregivers initiative in Zambia whose objective was to develop and test a risk-reduction workplace program for hospital staff. This was motivated by the recognition that hospital workers are often overlooked in HIV programming, and yet many are infected or affected by HIV. It was also motivated by the fact that hospital staff are heterogeneous, with both clinical and non-clinical staff having varying levels of understanding regarding HIV transmission. Caring for Caregivers was a peer education program targeted at hospital staff and implemented in two hospitals in Zambia, with a combined staff of …

This Horizons report from the Swaziland Ministry of Health and Social Welfare discusses findings from an intervention which aimed to reposition postnatal care within the context of a high HIV prevalence environment. The objectives were to determine if changes to the sexual and reproductive health guidelines on postnatal care would result in the timely and quality provision of key components of essential maternal and newborn care in the postnatal period, increase utilization of postnatal care services among all postpartum women, and improve the care and follow up of HIV-positive postpartum women and their infants. The study confirms that the introduction …

Improving Hospital-Based Quality Of Care In Vietnam By Reducing Hiv-Related Stigma And Discrimination, Khuat Thi Hai Oanh, Kim Ashburn, Julie Pulerwitz, Jessica Ogden, Laura Nyblade

HIV and AIDS

To address HIV-related stigma and discrimination, and improve the quality of care in the healthcare setting in Vietnam, the Institute for Social and Development Studies, the International Center for Research on Women, and the Horizons Program conducted intervention research in four hospitals. The study team conceptualized two fundamental causes of HIV-related stigma: 1) fear of casual transmission; and 2) negative values/social judgments and associations between HIV and certain behaviors and groups, such as sex workers and injecting drug users. Both intervention strategies successfully reduced stigma and discrimination toward HIV-positive patients in these healthcare settings. The findings show that addressing stigma …

The study was conducted in partnership with the Ministry of Education, the Kenya Institute of Education, the Teachers Service Commission, and UNICEF. Called Teachers Matter, the project’s main audience was primary and secondary school teachers. The purpose of the research was to assess whether such a program would improve teachers’ HIV-related knowledge, attitudes, and behaviors; increase the proportion of teachers seeking voluntary testing and counseling; and enhance their ability to cope with …

A Novel And Generalizable Organotypic Slice Platform To Evaluate Stem Cell Potential For Targeting Pediatric Brain Tumors., Shengwen Calvin Li, William Gunter Loudon

Department of Cancer Biology Faculty Papers

Brain tumors are now the leading cause of cancer-related deaths in children under age 15. Malignant gliomas are, for all practical purposes, incurable and new therapeutic approaches are desperately needed. One emerging strategy is to use the tumor tracking capacity inherent in many stem cell populations to deliver therapeutic agents to the brain cancer cells. Current limitations of the stem cell therapy strategy include that stem cells are treated as a single entity and lack of uniform technology is adopted for selection of clinically relevant sub-populations of stem cells. Specifically, therapeutic success relies on the selection of a clinically competent …

Fli-1 In B Cell Proliferation And Systemic Lupus Erythematosus, Sarah Gail Bradshaw

MUSC Theses and Dissertations

PBMC from patients with SLE and splenic lymphocytes from murine models of SLE demonstrate increased expression of the ETS transcription factor Fli-1. Transgenic overexpression of Fli-1 in normal mice leads to SLE-like disease. These findings suggest investigation of the role of Fli-1 in SLE may elucidate etiology of the disease and potential therapies. The MRL/lpr mouse is a model of SLE exhibiting increased lymphocytic expression of Fli-1. Reduction of Fli-1 expression by heterozygousity at the Fli-1 locus (Fli1+/-) results in decreased auto- and alloantibodies, proteinuria, and renal pathology; and drastically decreased mortality. Disruption of the C-terminal transactivation domain (Fli1ΔCTA/ΔCTA) reduces …

Moving Forward: Tackling Stigma In A Tanzanian Community, Laura Nyblade, Kerry Macquarrie, Gideon Kwesigabo, Aparna Jain, Lusajo Kajula, Fausta Philip, William Henerico Tibesigwa, Jessie K. Mbwambo

HIV and AIDS

The International Center for Research on Women, the Muhimbili University College of the Health Sciences, the Population Council, and Family Health International conducted an evaluation of a community-based effort to reduce stigma surrounding HIV infections in a peri-urban community in Tanzania. Results presented a mixed, but hopeful, picture for a way forward in tackling stigma at the community level. Tackling stigma requires that the individuals tasked with doing this undergo personal change. Programs can start by focusing stigma-reduction efforts on a smaller, more manageable geographical area and adding specific anti-stigma components to their portfolio of activities. Engaging community opinion leaders …

If You Build It, Will They Come? Kenya Healthy Start Pediatric Hiv Study: A Diagnostic Study Investigating Barriers To Hiv Treatment And Care Among Children, Karusa Kiragu, Katie D. Schenk, Julie Murugi, Avina Sarna

HIV and AIDS

In Kenya the proportion of eligible HIV-positive children receiving ART treatment is only 11 percent. This study explored and documented possible barriers in the community to accessing pediatric HIV testing and treatment, to guide the development of new interventions to encourage uptake. The study identified barriers such as cost, use of traditional healers, low knowledge of treatment options, attitudinal barriers, stigma, unique treatment issues, and dissatisfaction with available services. Additionally, healthcare workers missed opportunities to provide services and cited numerous service-side challenges. The study recommends prioritizing community awareness, mobile clinics, strengthening capacity of healthcare workers, supporting family-based HIV testing, and …

Evaluation Of A Simple Intervention To Increase Self- Efficacy For Independent Exercise In Cardiac Rehabilitation Participants, Sherry A. Barkley

Electronic Theses and Dissertations

Purpose: While benefits of exercise after a cardiac event are well documented, participation in and adherence to cardiac rehabilitation (CR) programs is often low. The purpose of this study was to test the effectiveness of a self- efficacy coaching intervention (SCI): a simple theory-based behavioral intervention to increase self-efficacy for independent exercise as well as independent exercise behavior in CR patients. It was hypothesized that persons receiving the SCI treatment (T) would have higher levels of self-efficacy for exercise and greater participation in independent exercise than participants in an attention control (C) group.
Methods: People referred to a hospitalbased CR …

Department of Microbiology and Immunology Faculty Papers

The enormous genetic variability reported in HIV-1 has posed problems in the treatment of infected individuals. This is evident in the form of HIV-1 resistant to antiviral agents, neutralizing antibodies and cytotoxic T lymphocytes (CTLs) involving multiple viral gene products. Based on this, it has been suggested that a comprehensive analysis of the polymorphisms in HIV proteins is of value for understanding the virus transmission and pathogenesis as well as for the efforts towards developing anti-viral therapeutics and vaccines. This study, for the first time, describes an in-depth analysis of genetic variation in Vpr using information from global HIV-1 isolates …

One-Year Treatment With Mometasone Furoate In Chronic Obstructive Pulmonary Disease, Peter M.A. Calverley, Stephen I. Rennard, Harold S. Nelson, Jill P. Karpel, Eduardo H. Abbate, Paul Stryszak, Heribert Staudinger

Journal Articles: Pulmonary & Critical Care Med

Many patients with chronic obstructive pulmonary disease (COPD) are treated with twice daily (BID) inhaled corticosteroids (ICS). This study evaluated whether daily PM mometasone furoate administered via a dry powder inhaler (MF-DPI) was equally effective compared to twice daily dosing.In a 52-week, randomized, double-blind, placebo-controlled study, 911 subjects with moderate-to-severe COPD managed without ICS received MF-DPI 800 microg QD PM, MF-DPI 400 microg BID, or placebo. The change from baseline in postbronchodilator forced expiratory volume in 1 second (FEV1), total COPD symptom scores, and health status as well as the percentage of subjects with a COPD exacerbation were assessed. Adverse …

Has The Hiv Epidemic Peaked?, John Bongaarts, Thomas Buettner, Gerhard Heilig, Francois Pelletier

Poverty, Gender, and Youth

This working paper reviews the highly diverse regional and country patterns of HIV epidemics and discusses possible causes of the geographic variation in epidemic sizes. The main finding of this analysis is that the HIV epidemic reached a major turning point over the past decade. The peak years of HIV incidence rates are past for all regions, and the peaks of prevalence rates are mostly in the past except in Eastern Europe, where it is expected to peak in 2008. But owing in part to the life-prolonging effect of antiretroviral therapy and to sustained population growth, the absolute number of …

Sexual Behavior And Sti/Hiv Status Among Adolescents In Rural Malawi: An Evaluation Of The Effect Of Interview Mode On Reporting, Barbara Mensch, Paul C. Hewett, Richard Gregory, Stephane Helleringer

Poverty, Gender, and Youth

This paper presents the results from an interview-mode experiment conducted by the Population Council with unmarried young women in rural southern Malawi. To collect data on sexual behavior and the dynamics of HIV transmission, respondents were randomly assigned to either an audio computer-assisted self-interview (ACASI) or a conventional face-to-face (FTF) interview. Clear evidence indicates that the mode of interviewing and probing concerning various sexual partnerships affects respondents’ reporting of their sexual activity, yet the results are not always in accordance with expectations. Reporting for “ever had sex” and “sex with a boyfriend” is higher in the FTF mode, whereas, when …

Autoimmune-Induced Preferential Depletion Of Myelin-Associated Glycoprotein (Mag) Is Genetically Regulated In Relapsing Eae (B6 × Sjl) F1 Mice, Dusanka S. Skundric, Rujuan Dai, Vaagn L. Zakarian, Weili Zhou

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Experimental autoimmune encephalomyelitis (EAE) is commonly used to investigate mechanisms of autoimmune-mediated damage to oligodendrocytes, myelin, and axons in multiple sclerosis (MS). Four distinct autoimmune mechanisms with subsequently distinct patterns of demyelination have been recognized in acute MS lesions. EAE correlates for those distinct patterns of MS lesions are unknown. An excessive loss of myelin-associated glycoprotein (MAG), as a result of distal oligodendrogliopathy, is found exclusively in the subtype III lesion. We sought to answer if types of demyelination in acute lesions during onset and relapse of EAE can replicate the specific patterns observed in MS acute lesions. …
