Filter by:Mental disorders have been shown to be associated with a number of general medical conditions (also referred to as somatic or physical conditions). The investigators aim to undertake a comprehensive study of comorbidity among those with treated mental disorders, by using high-quality Danish registers to provide age- and sex-specific pairwise estimates between the ten groups of mental disorders and nine groups of general medical conditions. The investigators will examine the association between all 90 possible pairs of prior mental disorders and later GMC categories using the Danish national registers. Depending on whether individuals are diagnosed with a specific mental disorder, the investigators will estimate the risk of receiving a later diagnosis within a specific GMC category, between the start of follow-up (January 1, 2000) or at the earliest age at which a person might develop the mental disorder, whichever comes later. Follow-up will be terminated at onset of the GMC, death, emigration from Denmark, or December 31, 2016, whichever came first. Additionally for dyslipidemia, follow-up will be ended if a diagnosis of ischemic heart disease was received. A "wash-out" period will be employed in the five years before follow-up started (1995-1999), to identify and exclude prevalent cases from the analysis. Individuals with the GMC of interest before the observation period will be considered prevalent cases and excluded from the analyses (i.e. prevalent cases were "washed-out"). When estimating the risk of a specific GMC, the investigators will consider all individuals to be exposed or unexposed to the each mental disorder depending on whether a diagnosis is received before the end of follow-up. Persons will be considered unexposed to a mental disorder until the date of the first diagnosis, and exposed thereafter.
This study deploys a novel digital pill with Emtricitabine/Tenofovir (TDF/FTC) among MSM with substance use to monitor PrEP adherence. The investigators will enroll N=15 HIV uninfected MSM with self reported substance use who are on PrEP or initiating PrEP to use digital pills over encapsulating TDF/FTC for 3 months. The investigators will assess the feasibility of using digital pills in this study population as well as understand the acceptability of digital pills for adherence measurement using semi-structured individual interviews. Additionally, the investigators will measure adherence over time, as well as episodes of suboptimal PrEP adherence.
This study will develop and test a program to deliver PrEP care in underserved communities in Mississippi (MS) through telemedicine, distance-based, clinical care delivered in local community based organizations (CBOs). The intervention will be developed in collaboration with medical specialists at the University of Mississippi Medical Center (UMMC) and local CBO stakeholders (providers, administrators and patients). Approximately 75 individuals will be recruited from CBOs in MS. Participants will be able to receive PrEP counseling in the CBO and PrEP care via telemedicine from a PrEP specialist at UMMC. Participants will complete three assessments in the six months after enrolling. Our study will provide a wealth of information about PrEP-related outcomes and HIV testing among MS residents living in underserved communities. If successful, this program will be able to be disseminated to other CBOs in the South.
HIV-infected patients are 30- to 100-fold more susceptible to invasive pneumococcal diseases. Pneumococcal vaccination is the best way to decrease the large pneumococcal disease burden, but the optimal timing of vaccination is still unclear. HIV-infected subjects aged ≥ 18 years were recruited and divided into two age-matched groups: group 1 (subjects with CD4 T-cell counts ≥350 cells/µL) and group 2 (subjects with CD4 T-cell counts <350 cells/µL). Multiplex opsonophagocytic killing assay was used to compare immunogenicity after the immunization of 13-valent pneumococcal conjugate vaccine (PCV13).
Population mobility is common in South Africa, but important research gaps exist describing this mobility and its impact on engagement in HIV care, particularly among pregnant and postpartum women. Through this study, the investigators propose to test a smartphone application - CareConekta - to conduct essential formative work on mobility and evaluate this app as an intervention to facilitate engagement in HIV care during times of mobility. This work is critical to adapting CareConekta for widespread use, providing critical information about mobility during the peripartum period and the impact on engagement in HIV care, and piloting this intervention to improve engagement.
The long-term goal of this project is to improve HIV and substance use outcomes and reduce recidivism for HIV+ substance users released from jail. The overall objective of the proposed R34 project is to develop and pilot test a multi-sector community-clinic collaborative intervention that can subsequently be implemented on a larger scale (as part of a future R01) to achieve this goal. Our central hypothesis is that HIV+ substance users released from jail can successfully overcome obstacles to re-entry and continuity of HIV care with individualized, culturally competent assistance in navigating both social and medical services. Aim 1: Develop and refine a collaborative CHW and re-entry program intervention that targets HIV outcomes, substance use and recidivism in HIV+ jail releasees. Aim 2: Conduct a pilot randomized controlled trial comparing the collaborative intervention (n=40) compared to treatment as usual (n=40) in HIV+ substance users released from jail.
High and sustained adherence is critical for achieving the individual and public health benefits of HIV antiretroviral therapy (ART). Electronic adherence monitors provide a detailed understanding of adherence and enable real-time interventions. Research has shown the benefit of these monitors and low-cost models have recently become available; however, their use to date has largely been confined to the research context. This study is an implementation science-driven assessment of strategies to improve uptake of electronic adherence monitoring and associated interventions for routine, clinical delivery of ART in Uganda. The study consists of two aims. In Aim 1, the investigators will conduct multi-level formative interviews to design a preliminary implementation strategy. In Aim 2, the investigators will use an iterative approach to optimize the implementation strategy. All work will be guided by the Consolidated Framework for Research Implementation.
The aim of this study is to compare the clinical response and mortality rate by an opportunistic disease in HIV-infected individuals who start immediate versus conventional antiretroviral therapy. Immediate ART (iART) is defined as starting antiretroviral therapy in the first 48 hours after the hospitalization. Conventional ART (cART) is defined as starting antiretroviral therapy once the opportunistic infection is under control at the discretion of infectious disease specialist.
This mixed methods study will utilize a randomized step-wedge design to assess the impact of point-of-care (POC) versus conventional early infant diagnosis (EID) on key outcomes including timely return of results to caregivers and time to initiation on treatment for HIV-infected infants. Data will be collected through longitudinal clinical follow-up and medical chart extraction of routine records and lab forms. Feasibility and acceptability data will be collected through interviews with mothers/caregivers of HIV-exposed infants, and community focus groups.
Many men living with HIV (MLWH) want to have children. HIV-RNA suppression can minimize sexual HIV transmission risks while allowing for conception. The study will evaluate a safer conception intervention that leverages men's motivations to have healthy babies in order to promote serostatus disclosure and early ART initiation. The intervention is based on the investigators' Safer Conception Conceptual Framework, which considers individual, dyadic, and structural factors that affect periconception risk behavior.
