Preventing Mother-To-Child Transmission Of Human Immunodeficiency Virus-1 (Hiv-1): Effects Of Intrapartum And Neonatal Single-Dose Nevirapine Prophylaxis And Subsequent Hiv-1 Drug Resistance At Antiretroviral Treatment Initiation, Amanda L. Harmon

CMC Senior Theses

The prevention of mother-to-child transmission is one of the most powerful tools in human immunodeficiency virus type 1 (HIV-1) prevention and has huge potential to improve both maternal and child health. In the absence of any preventative measures, infants born to and breastfed by their HIV-positive mothers have roughly a one-in-three chance of acquiring the infection themselves. HIV can be passed on from mother-to-child during pregnancy, during labor and delivery, and even after during breastfeeding.

Intrapartum and neonatal single-dose nevirapine (sd-NVP) is the foundation of preventing mother-to-child transmission in lower resource settings where it has been used alone or as …

Hiv: Make The Diagnosis And Take The Next Step, Julie G. Stewart, Amy R. Weinberg

Nursing Faculty Publications

With the CDC urging screening for all willing patients, providers will be testing and managing a growing number of HIV-positive individuals.

The CDC estimates that with more than 40,000 new infections annually, more than 1.2 million people in the United States are living with HIV-and 24% to 27% may not be aware of their infection status.1 Studies have shown that HIV is often diagnosed late in the disease process, when the individual has already developed AIDS, which typically occurs 8 to 11 years after HIV infection.2 Research also points to missed opportunities to offer HIV testing and diagnose the infection …

Ccl2 Responses To Mycobacterium Tuberculosis Are Associated With Disease Severity In Tuberculosis, Zahra Hasan, Jacqueline M. Cliff, Hazel M. Dockrell, Bushra Jamil, Muhammad Irfan, Mussarat Ashraf, Rabia Hussain

Section of Pulmonary & Critical Care

Background

Leucocyte activating chemokines such as CCL2, CCL3, and CXCL8 together with proinflammatory IFNγ, TNFα and downmodulatory IL10 play a central role in the restriction of M. tuberculosis infections, but is unclear whether these markers are indicative of tuberculosis disease severity.

Methodology

We investigated live M. tuberculosis- and M. bovis BCG- induced peripheral blood mononuclear cell responses in patients with tuberculosis (TB) and healthy endemic controls (ECs, n = 36). TB patients comprised pulmonary (PTB, n = 34) and extrapulmonary groups, subdivided into those with less severe localized extrapulmonary TB (L-ETB, n = 16) or severe disseminated ETB (D-ETB, …

The Curse Of A Generation: Evaluating The Effects Of Gender Roles And Marriage On Hiv/Aids In Sub-Saharan Africa And Developing An Efficient Prevention Plan, Mark B. Krom

Senior Honors Theses

HIV/AIDS research in sub-Saharan Africa shows an important relationship between gender roles, marriage, and HIV prevalence. Research is collected and analyzed, and cultural issues are addressed in order to develop a prevention plan. The African church seems to be an efficient venue through which to reach sub-Saharan Africa, and the most efficient prevention plan to curb HIV/AIDS is abstinence.

The treatment of viral diseases remains an intractable problem facing the medical community. Conventional antivirals focus upon selective targeting of virus-encoded targets. However, the plasticity of viral nucleic acid mutation, coupled with the large number of progeny that can emerge from a single infected cells, often conspire to render conventional antivirals ineffective as resistant variants emerge. Compounding this, new viral pathogens are increasingly recognized and it is highly improbable that conventional approaches could address emerging pathogens in a timely manner. Our laboratories have adopted an orthogonal approach to combat viral disease: Target the host to deny the pathogen the ability …

“Riding Bareback”: Factors Involved In The Development Of A Bareback Identity, Scott Charles Musgrove

Antioch University Dissertations & Theses

Researchers in the area of HIV prevention have long been aware of the rising incidence of unprotected sex among men who have sex with men (MSM). In recent years researchers have witnessed the emergence of the behaviors, attitudes and practices that discriminate between those of the MSM community who strictly and consistently adhere to safer sex practices, those who inconsistently practice safer sex, and those who eschew protected sex altogether. Understanding the factors that motivate the development and adoption of a "barebacker identity" in spite of serious potential for HIV infection may well help support the efforts of public agencies …

Health Communication Theories: Implications For Hiv Reporting In Asia And The Pacific, Trevor Cullen

Research outputs pre 2011

This paper focuses on the expanding HIV (Human Immunodeficiency Virus) epidemic in parts of Asia and the Pacific region and recommends the adoption of insights from particular health communication theories. The author argues that these paradigms can assist in broadening the current scope and content of HIV reporting. One theory in particular - Social Change Communication (SCC) - challenges the media to extend the framing of HIV from primarily a health story to one that is linked to more macro socio-economic, cultural and political factors. Asian and Pacific countries that have an emerging or expanding HIV epidemic need to realise …

Do Hospitalists Or Physicians With Greater Inpatient Hiv Experience Improve Hiv Care In The Era Of Highly Active Antiretroviral Therapy? 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 …

Gender Differences In Hiv And Hepatitis C Related Vulnerabilities Among Aboriginal Young People Who Use Street Drugs In Two Canadian Cities, Azar Mehrabadi, Katharina Paterson, Margo Pearce, Sheetal Patel, Kevin J. Craib, Akm Moniruzzaman, Martin T. Schechter, Patricia M. Spittal

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 …

Retrocyclin Rc-101 Overcomes Cationic Mutations On The Heptad Repeat 2 Of Hiv-1 Gp41, Christopher Fuhrman

Electronic Theses and Dissertations

Retrocyclin RC-101, a θ-defensin with lectin-like properties, potently inhibits infection by many HIV-1 subtypes by binding to the heptad repeat (HR)-2 region of gp41 and preventing six-helix bundle formation. In the present study, we used in silico computational exploration to identify residues of HR2 that interacted with RC-101 and then analyzed the HIV-1 Sequence Database at LANL for residue variations in the HR1 and HR2 segments that could plausibly impart in vivo resistance. Docking RC-101 to gp41 peptides in silico confirmed its strong preference for HR2 over HR1, and implicated residues crucial for its ability to bind HR2. We mutagenized …

Aids-Associated Viral Oncogenesis: Overview, Charles Wood

Nebraska Center for Virology: Faculty Publications

It has been 25 years since the acquired immunodeficiency syndrome (AIDS) was first described and over 23 years since the human immunodeficiency virus (HIV) associated with the disease was first discovered. In spite of the tremendous progress that was made in understanding both the disease and the virus, there are still millions of people infected, died, or living with the disease. As for the year 2005 alone, the Joint United Nations Programme on HIV/AIDS (http://www.UNAIDS.org) estimates that there are about 40 million people living with HIV/AIDS globally, and approximately 3 million people died from AIDS in the year. Globally, it …

Hiv-Positive Inmates Released From Nevada’S Prisons In 2001: Results From Matching Health Division And Corrections’ Databases, Paul G. Devereux, Kristen Clements-Nolle, Sharon Clodfelter, Jessey Bargmann-Losche, Miguel Feroro, Wei Yang

Nevada Journal of Public Health

It is estimated that about one quarter of all HIV-infected individuals in the United States are released from a correctional facility each year. To better understand the needs of inmates with HIV exiting the prison system, a partnership with the Nevada State Health Division (NSHD), the Nevada Department of Corrections (DOC), and the University of Nevada, Reno School of Public Health was formed to examine this population using information contained in existing databases. An analysis of DOC data matched with the data from the HIV/AIDS Reporting System (HARS) maintained by the NSHD identified 2,802 HIV-negative inmates (2,451 males and 350 …

Unruly Corporeality: Aids, Immigration And The Imagined Australian Body, Zoë Anderson

Reconstruction: Studies in Contemporary Culture

Particular bodies within the Australian nation can be seen to threaten to disrupt and destabilize dominant notions of cultural citizenship. Understood through intricate intersections of ethnicity, gender and sexuality, 'Australianness' - and its correlation to the geographical nation - is constantly monitored. Crucial here is the manner in which boundaries of whiteness, and 'true Australianess', are reconstituted, fuelling avoidance of the ambiguities of national belonging and ensuring the enduring pathologisation of the 'un'Australian. In particular, discursive associations between HIV/AIDS and the 'foreign' as perceived contaminates to the nation operate to reinforce these understandings. Here, the threat of disease both informs, …

Optimal Therapy Regimens For Treatment-Resistant Mutations Of Hiv, Weiqing Gu, Helen Moore

All HMC Faculty Publications and Research

In this paper, we use control theory to determine optimal treatment regimens for HIV patients, taking into account treatment-resistant mutations of the virus. We perform optimal control analysis on a model developed previously for the dynamics of HIV with strains of various resistance to treatment (Moore and Gu, 2005). This model incorporates three types of resistance to treatments: strains that are not responsive to protease inhibitors, strains not responsive to reverse transcriptase inhibitors, and strains not responsive to either of these treatments. We solve for the optimal treatment regimens analytically and numerically. We find parameter regimes for which optimal dosing …

A Mathematical Model For Treatment-Resistant Mutations Of Hiv, Helen Moore, Weiqing Gu

All HMC Faculty Publications and Research

In this paper, we propose and analyze a mathematical model, in the form of a system of ordinary differential equations, governing mutated strains of human immunodeficiency virus (HIV) and their interactions with the immune system and treatments. Our model incorporates two types of resistant mutations: strains that are not responsive to protease inhibitors, and strains that are not responsive to reverse transcriptase inhibitors. It also includes strains that do not have either of these two types of resistance (wild-type virus) and strains that have both types. We perform our analysis by changing the system of ordinary differential equations (ODEs) to …

Aids: Prophecy And Present Reality, Victor De Gruttola, William Ira Bennett

New England Journal of Public Policy

Mathematical modeling of the AIDS epidemic can be useful for policymakers even though precise projections are not possible at this time. Models are useful in establishing ranges for current and future prevalence of HIV infection and incidence of AIDS, as well as in predicting the effect of a given intervention strategy. Most decision makers are using models implicitly when they use epidemiological information as a basis for policy; formulating a model explicitly permits examination of the underlying assumptions. By creating and testing a variety of models, an investigator can determine whether the models reflect more the underlying assumptions or the …
