Hiv Diagnosis Disclosure To Infected Children And Adolescents; Challenges Of Family Caregivers In The Central Region Of Ghana, Anna Hayfron-Benjamin, Dorcas Obiri-Yeboah, Stephen Ayisi-Addo, Peter Mate Siakwa, Sylvia Mupepi

Peer Reviewed Articles

Background

Disclosure of Human Immunodeficiency Virus (HIV) to infected older children and adolescents is essential for both personal health maintenance and HIV prevention within the larger population. Non-disclosure of HIV status has been identified as one of the potential barriers to optimum adherence especially in children and adolescents. Like many other countries in the SSA region, Ghana has significant number of children and adolescents infected by HIV, who have increased survival times, due to increased access to ART. However, both family caregivers and healthcare workers face an array of challenges with the disclosure process, including the timing, what information about …

Introduction The period of transition from pediatric to adult care has been associated with poor health outcomes among 10–19 year old adolescents living with HIV (ALHIV). This has prompted a focus on the quality of transition services, especially in high ALHIV-burden countries. Due to lack of guidelines, there are no healthcare transition standards for Nigeria’s estimated 240,000 ALHIV. We conducted a nationwide survey to characterize routine transition procedures for Nigerian ALHIV. Materials and methods This cross-sectional survey was conducted at public healthcare facilities supported by five local HIV service implementing partners. Comprehensive HIV treatment facilities with ≥1 year of HIV …

Background: The suboptimal rate of viral suppression among persons aged 13 years and older and residing in 37 states and the District of Columbia leaves considerable opportunities for onward transmission and contributes to poor health outcomes. Men who have sex with men (MSM) represent one of the most at-risk groups in the United States. There is a clear and continued need for innovative adherence support programs to optimize viral suppression. To address this gap, we designed and are implementing a randomized controlled trial (RCT) to test the efficacy of the Thrive with Me intervention for MSM living with HIV. Critical …


Global Stability For A 2n + 1 Dimensional Hiv/Aids Epidemic Model With Treatments, Olusegun Michael Otunuga May 2018

Global Stability For A 2n + 1 Dimensional Hiv/Aids Epidemic Model With Treatments, Olusegun Michael Otunuga

Mathematics Faculty Research

In this work, we derive and analyze a 2n + 1-dimensional deterministic differential equation modeling the transmission and treatment of HIV (Human Immunodeficiency Virus) disease. The model is extended to a stochastic differential equation by introducing noise in the transmission rate of the disease. A theoretical treatment strategy of regular HIV testing and immediate treatment with Antiretroviral Therapy (ART) is investigated in the presence and absence of noise. By defining R0, n, Rt, n and Rt,n as the deterministic basic reproduction number in the absence of ART treatments, deterministic basic reproduction number in the presence of …

Department of Sociology: Faculty Publications

Understanding the short- and long-term transmission dynamics of blood-borne illnesses in network contexts represents an important public health priority for people who inject drugs and the general population that surrounds them. The purpose of this article is to compare the risk networks of urban and rural people who inject drugs in Puerto Rico. In the current study, network characteristics are drawn from the sampling “trees” used to recruit participants to the study. We found that injection frequency is the only factor significantly related to clustering behavior among both urban and rural people who inject drugs.

“We Hide…”: Perceptions Of Hiv Risk Among Black And Latino Msm In New York City, Ashley Murray, Zaneta Gaul, Madeline Y. Sutton, Jose Nanin

Publications and Research

Black and Latino men who have sex with men (BLMSM) are disproportionately infected with HIV; they comprised 66% of HIV diagnoses among men who have sex with men (MSM) in the United States in 2015. Risk factors for HIV infection among BLMSM include a high community prevalence of diagnosed and undiagnosed HIV/STDs, and dense sex partner networks. Perceptions of HIV risk among BLMSM were explored to inform HIV prevention efforts. During 2011–2012, semistructured interviews were conducted with BLMSM in New York City. Using computer-assisted thematic analyses (NVivo), transcribed interview responses to questions regarding HIV risk for main themes were examined. …
