The Lived Experiences of HIV+ Community Health Workers Serving HIV+ Clients

Jackson, Phronie Lynn 01 January 2016 (has links)
Numerous studies have focused on the effectiveness of community health worker (CHW) programs in producing positive health behaviors and health outcomes for the clients CHWs serve; however, there has been a gap in the literature regarding how the health of HIV + CHWs is impacted by their jobs. A phenomenological design was used to gain insight into the lived experiences of HIV+ CHWs (HIVCHW) who provided services to HIV positive clients. Fifteen HIVCHW were recruited using criteria and snowball techniques. Data were collected via audio recorded personal interviews regarding respondents' perceptions of their work and how it impacted their own health and wellbeing. The data were organized by hand creating charts with pen and paper. Lazarus's theory of stress and coping was used to understand the data and aided in the analysis. The key findings indicated that while the majority of participants had an overall positive perception of the experience of being HIVCHWs, they also indicated that being a CHW impacted their health and well-being. Stress and stressful situations were among the impacts most often referenced by the study participants. The study is socially significant because it may offer the workforce of HIVCHWs empowerment to self-advocate for tools such as stress and time management training and mentors to support healthy work-life balance. In addition, this study may help to prevent or reduce rates of adverse health outcomes such as pain and burnout that HIVCHWs reported experiencing.

Lipoatrophy in HIV-infected children on antiretroviral therapy

Innes, Steven Eugene Vere 03 1900 (has links)
Thesis (PhD)--Stellenbosch University, 2013. / Bibliography / ENGLISH ABSTRACT: Introduction: Lipoatrophy is a common adverse effect of stavudine and this effect is strongly dose-dependent. Stavudine remains the most commonly used paediatric antiretroviral drug in sub-Saharan Africa, yet when the current study began in 2009, the prevalence and severity of lipoatrophy in children on antiretroviral therapy in sub-Saharan Africa had never been studied. The development of lipoatrophy may have serious and far-reaching consequences for patients and their families. The off-label stavudine dosing method, prescribed to children whose caregivers do not have access to a refrigerator, in which the contents of an adult capsule is mixed into tap water, has potential for over-dosing or under-dosing. In addition, children on stavudine continue to be exposed to a disproportionately high dose out of line with the reduced adult dose. Aims: 1. a) To investigate the prevalence and risk factors for lipoatrophy in HIV-infected children in Southern Africa b) To identify a simple anthropometric screening tool to detect early lipoatrophy in children 2. To validate the off-label stavudine dosing method prescribed to children whose caregivers do not have access to a refrigerator, with a view to reducing the recommended dose and thereby the side-effects. Methods: 1. a) We recruited pre-pubertal children on antiretroviral therapy from a family HIV clinic in our facility. Lipoatrophy was identified by two experienced paediatric HIV clinicians using a standardized grading scale. A dietician performed dietary assessment and anthropometric measurements. Previous antiretroviral exposures were recorded. A subset of recruits received Dual-Energy X-ray Absorbtiometry scanning. b) Anthropometric measurements in children with and without lipoatrophy were compared using multivariate linear regression adjusting for age and gender. The most discerning anthropometric variables underwent Receiver Operating Characteristic curve analysis to identify the most appropriate diagnostic cut-off. 2. a) Accuracy of the standard off-label stavudine dosing method was investigated using high-performance liquid chromatography to recover active drug from solutions made up using the prescribed method. This was compared to the stated drug content of the capsules. b) Bioavailability was investigated by performing a randomized crossover pharmacokinetic study wherein healthy HIV-seronegative adult volunteers received one of two generic stavudine capsule formulations, either intact or mixed in water using the prescribed method. Plasma stavudine concentrations were assayed by liquid chromatography tandem mass spectrometry. Results: 1. a) Prevalence of lipoatrophy was 36%, and incidence was 12% per person-year. Adjusted odds ratio for developing lipoatrophy was 1.9 (CI: 1.3–2.9) for each additional year of accumulated exposure to standard-dose stavudine. b) Baseline biceps skin-fold thickness correlated well with maximum lipoatrophy grading score at any site, giving a partial correlation coefficient of 0.33 (p=0.0006), and a receiver operating characteristic area-under-curve value of 0.75 (CI: 0.64 – 0.84). Biceps skin-fold thickness <5mm at baseline had a sensitivity of 89% (CI: 67–100%) and a negative predictive value of 97% (CI: 91–100%) for predicting which children would go on to develop lipoatrophy by 15 month follow-up. Specificity was 60% (CI: 46–75%) and positive predictive value was 32% (CI: 14–50%). 2. a) Recovery of active drug from solution was 97.1%, 97.4% and 93.8% for the proprietary and two generic formulations respectively. b) Pharmacokinetic parameters of the off-label dosing method were well within the target range of intact capsule dosing for both generics. Conclusions: 1. a) The prevalence and incidence of lipoatrophy in pre-pubertal children on antiretroviral therapy in South Africa is high. Cumulative exposure to standard-dose stavudine was the greatest risk factor for lipoatrophy. b) Biceps skin-fold thickness provided reasonable sensitivity and specificity to detect and predict lipoatrophy in pre-pubertal children on antiretroviral therapy. 2. The off-label dosing method for stavudine prescribed to children whose caregivers do not have access to a refrigerator is reasonably accurate and is bioequivalent to intact capsule administration. / AFRIKAANSE OPSOMMING: Inleiding: Lipoatrofie is 'n algemene nadelige uitwerking van stavudien en hierdie effek is sterk dosis-afhanklike. Stavudien bly die mees algemeen gebruikte paediatriese antiretrovirale medikasie in sub-Sahara Afrika, maar toe ons studie begin het, was lipoatrofie in kinders op antiretrovirale terapie in sub-Sahara Afrika nog nooit voorheen bestudeer nie. Die ontwikkeling van lipoatrofie kan ernstige en verreikende gevolge vir die pasiënt en hul familie hê. Die af-etiket stavudien dosering metode voorgeskryf aan kinders wie se versorgers nie toegang tot 'n yskas het nie het 'n aansienlike potensiäal vir oor-dosering of onder-dosering. Daarbenewens, is kinders op stavudien blootgestel aan 'n disproporsionele hoë dosis uit-pas met die verminderde volwasse dosis. Doelwitte: 1. a) Om ondersoek in te stel na die voorkoms en risiko faktore vir lipoatrofie in MIV-geïnfekteerde kinders in Suid Afrika b) Om 'n eenvoudige antropometriese instrument te identifiseer om vroeë lipoatrofie op te spoor in kinders op antiretrovirale medikasie 2. Om die af-etiket stavudien dosering metode wat voorgeskryf is aan kinders wie se versorgers nie toegang tot 'n yskas het nie te valideer, met 'n oog op die vermindering van die aanbevole dosis Metodes: 1. a) Ons het 'n groep van onder-puberteitsjarige kinders op antiretrovirale terapie gewerf uit 'n familie MIV kliniek in ons fasiliteit. Lipoatrofie is geïdentifiseer deur twee ervare MIV pediaters deur gebruik van 'n gestandaardiseerde gradering skaal. 'n Diëetkundige het diëet assessering en antropometriese metings uitgevoer. Vorige antiretrovirale blootstellings is aangeteken. In 'n subset was Dual-energie X-straal Absorbtiometry (DXA) skandering uitgevoer. b) Antropometriese metings in kinders met en sonder lipoatrofie is vergelyk met behulp van meerveranderlike lineêre regressie aangepas vir ouderdom en geslag. Die mees kieskeurige antropometriese veranderlikes het Receiver Operating Curve analise ondergaan om die mees geskikte diagnostiese afgesnypunt te identifiseer. 2. a) Akkuraatheid is ondersoek deur gebruik te maak van hoë werkverrigting vloeistofchromatografie om aktiewe medikasie vanuit oplossings te herstel, wat gemeng is soos aangedui deur die voorgeskrewe af-etiket dosering metode. b) Biobeskikbaarheid is ondersoek deur die uitvoering van 'n ewekansige oorgesteekde farmakokinetiese studie waarin gesonde MIV- negatiewe volwasse vrywilligers een van twee generiese stavudien kapsule formulerings ontvang het, óf heel of in water gemeng soos aangedui deur die voorgeskrewe af-etiket dosering metode. Plasma stavudien konsentrasies is gemeet deur vloeistofchromatografie tandem massaspektrometrie. Uitslae: 1. a) Voorkoms van lipoatrofie was 36%, en insidensie was 12% per persoon-jaar. Aangepaste Odds ratio vir die ontwikkeling van lipoatrofie was 1,9 (CI: 1,3-2,9) vir elke addisionele jaar van opgehoopte blootstelling aan standaard dosis stavudien. b) Biceps vel-vou dikte <5mm het 'n sensitiwiteit van 89% (CI: 83-96%) en 'n negatiewe voorspellende waarde van 90% (CI: 84-96%) vir die opsporing en voorspelling van lipoatrofie. 2. a) Herwinning van aktiewe medikasie uit oplossings was 97,1%, 97,4% en 93,8% vir die oorspronklike en twee generiese formulerings onderskeidelik. b) Farmakokinetiese parameters van die af-etiket dosering metode was wel binne die teikenband van ongeskonde kapsule dosering vir beide generiese formulerings. Gevolgtrekkings: 1. a) Die voorkoms van lipoatrofie in onder-puberteitsjarige kinders op antiretrovirale terapie in Suid-Afrika is hoog. Die bedrag stavudien waaraan kinders blootgestel is moet hersien word. Die standaard stavudien dosis vir kinders moet herge-evalueer word. b) Biceps vel-vou dikte het redelike goeie sensitiwiteit en spesifisiteit om lipoatrofie op te spoor en te voorspel. 2. Die af-etiket dosering metode vir stavudien voorgeskryf aan kinders wie se versorgers nie toegang tot 'n yskas het nie is redelik akkuraat en is bio-ekwivalent aan ongeskonde kapsule administrasie.

Erythrocyte apoptosis (erythroptosis) and anaemia in chronic HIV-1 infection : relationship with immune activation and viraemia

Loots, Stanley 12 1900 (has links)
Thesis (MScMedSc)-- Stellenbosch University, 2013. / ENGLISH ABSTRACT: Chronic HIV-1 infection is characterized by extensive inflammation/immune activation and also by anaemia. Macrophages and neutrophils produce reactive oxygen species (ROS) which can cause damage to surrounding cells, including erythrocytes. Damaged erythrocytes may die by apoptosis (erythroptosis) or be tagged for clearance by monocytes/ macrophages. In this study we investigated HIV-1-associated anaemia and erythroptosis in asymptomatic, untreated HIV-1 infected individuals and how it relates to oxidative stress and immune activation. / AFRIKAANSE OPSOMMING: Chroniese MIV-1 infeksie word gekenmerk deur uitgebreide inflammasie/immuun aktivering en ook deur anemie. Makrofage en neutrofiele produseer reaktiewe suurstof spesies (ROS), wat kan skade aan omliggende selle, insluitend rooibloedselle veroorsaak. Beskadigde rooibloedselle kan sterf deur apoptose (erythroptosis) of gemerk vir klaring deur monosiete/makrofage. In hierdie studie het ons ondersoek MIV-1-verwante bloedarmoede en erythroptosis in asimptomatiese, onbehandelde MIV-1 besmette individue en hoe dit verband hou met oksidatiewe stres en immuun aktivering. / The Poliomyelitis Research Foundation (PRF

An exploration of the stigma experienced by women who are living with HIV/AIDS.

Roman, Gail Sandra. January 2006 (has links)
<p>The effects of the spread of HIV/AIDS place a great burden on women and children, who will probably suffer most in terms of social and economic deprivation. Since HIV/AIDS is linked to social taboos such as sexuality, drug use and death, there are enormous levels of ignorance, denial, fear and intolerance in most communities. These prejudices lead to the stigmatisation and discrimination of people who are living with HIV/AIDS. Moreover the illness, as it is sexually transmitted, has been conflated with sexual excess, lack of morals, and those already stigmatised such as sex workers with associated discourses of blame, shame and guilt. Generally, responses to HIV and those living with HIV have served to reflect, legitimise and reproduce broader social inequalities on the basis of sexual orientation, gender, race and class. Stigma is the reason why many people who are living with HIV/AIDS, choose not to disclose their status and seek apposite assistance. This study explored the stigma experienced by a group of women who are living with HIV/AIDS and to develop a deeper understanding of whether these experiences are complicated by social responses.</p>

Heart Rate Variability as an Indicator of Stress and Resilience in HIV+ Adults: An Analysis of a Stigma Related Stress Induction

Lewis, Kimberly 08 1900 (has links)
Learning of a positive diagnosis of HIV may be one of the most challenging and stressful events in life. The memory of this event is emotionally laden, and even years later evokes an emotional response. Similarly, many people living with HIV (PLH) have memories of the first time they were treated differently because of their diagnosis. While research frequently examines the subjective of stress, few studies have examined biological markers of stress in people living with HIV. Heart Rate Variability offers a non-invasive measure of stress. Beyond serving as a biological marker for stress, changes in HRV are also associated with emotional functioning. Research demonstrates decreased HRV levels in patients with Depression, Anxiety, and PTSD. We conducted a repeated measures MANOVA to examine effects of stress induction on HRV in individuals with high and low levels of HIV-related stigma. We found that the high stigma group was significantly different from the low stigma group in regard to changes in participants’ HRV, Wilks’ λ = .50, F (1, 51) = 11.63, p < .001. A hierarchical linear regression examined the relationship between HRV and other measures of stress (Heart Rate and Blood Pressure). We found that systolic blood pressure and heart rate in the stress condition were predictive of HRV (adjusted R2=.29, F (5,46) =4.07, p<.01). Results of our study support the use of HRV as a measure of stress in HIV-positive adults. Additionally, the results of our study demonstrate significant relationships between stigma, social support and stress in HIV-positive adults.

Care and support model for health care providers of HIV and AIDS patients in the public hospitals of Limpopo Province

Moshidi, Maria Lebeko January 2018 (has links)
Thesis (Ph.D. (Nursing Science)) -- University of Limpopo, 2018 / Introduction: Health care workers have a pivotal role in the management of Human Immune Deficiency Virus (HIV) and Acquired Immune Deficiency Syndrome (AIDS) and their well-being is consequently crucial as it could impact negatively on the quality of caregiving. With the development of a care and support model, the needs of health care workers can be identified and catered for, and quality patient care will be rendered through well-cared and supported health care workers. Purpose: The purpose of this study was to develop a care and support model for health care providers of patients diagnosed with HIV and AIDS in the public hospitals of the Limpopo Province. A key step in the development of a model for care and support is to explore and describe the experiences of professional nurses regarding care and support they receive while providing care to HIV and AIDS patients in the public hospitals of Limpopo Province Methods: A qualitative, descriptive, exploratory and contextual design was the method used which guided the development of the model. The population of the study were the professional nurses in five public hospitals from each district of the Limpopo Province. These hospitals were selected because they all shared similar characteristics of having clinics where HIV and AIDS patients receive care. The sample was purposively selected. The sample size was 20 professional nurses which was determined by data saturation, meaning that four professional nurses who worked for 24 months or more per public hospital were selected. Data were collected through face-to-face interviews and an audiotape was used to record all unstructured interview sessions conducted. Analysis of data were done through using an open-coding method in accordance with Tech’s qualitative data methodology to develop a model. Results: The research findings revealed emotional and physical strain due to shortage of staff and heavy workload which was exacerbated by staff turnover and high absenteeism. Exhaustion, fatigue, development of work-related vi illnesses and increased level of stress were also challenges experienced which led to increased customer complaints and decreased quality of service provided to patients. Many professional nurses were not trained in the management of patients with HIV and AIDS, but were expected to execute their activities competently. There was also lack of counselling, debriefing sessions, recognition and rewarding systems for the health professionals who were taking care of those patients. Recommendations: This Care and Support Model provides strategies to be used by the managers in public hospitals of Limpopo Province to enhance care and support to health care providers of HIV and AIDS patients. The model should be implemented at various public hospitals throughout Limpopo Province and feedback provided so that it could be further developed and refined. Conclusion: The results indicated that health care providers of HIV and AIDS patients were deprived of the necessary care and support during provision of care to HIV and AIDS patients. A model for care and support as a strategy to assist the managers to offer care and support to health care providers of HIV and AIDS has been developed. The model is a contribution to the nursing management, the government and it serves as a guideline for improving the quality of patient care through well-cared and supported health care workers.

Individual characteristics and vocational rehabilitation services as predictors of employment for state/federal vocational rehabilitation consumers with HIV/AIDS

Jung, Youngoh, 1975- 11 September 2012 (has links)
With greater advancement in medical treatments for individuals with Human Immunodeficiency Virus (HIV) and Acquired Immunodeficiency Syndrome (AIDS), a growing numbers of individuals living with HIV/AIDS are contemplating returning to the workplace. However, they have been faced with barriers to employment and have demonstrated a need for vocational rehabilitation (VR) services. The purpose of this study was to identify predictors of employment outcomes of individuals living with HIV/AIDS, who used the state/federal VR program services, using the Rehabilitation Services Administration (RSA-911) data file from Fiscal Year 2006. Data analyses were conducted using descriptive statistics, bivariate analyses (chi-square analyses, independent t-tests, and ANOVAs), and binary logistic regression using cross validation. Results of the study indicated that of socio-demographic, health, and VR service variables, service variables were only found to be significantly related to employment outcomes. Job search assistance, job placement assistance, and on the job support were found to be significant predictors of successful employment outcomes at closure. In addition, higher costs of purchased services increased the likelihood of being employed at closure. However, the longer the length of VR program participation was, the lower the likelihood of being employed at closure was. Among participants with successful employment outcomes at closure, differences were significant between participants earning less than $200.00 per week and participants earning equal to or higher than $500.00 per week. Participants with less than $200.00 of weekly earnings were more likely to be African Americans, to have lower education levels than an associate degree at closure, to have service occupations or clerical and sales occupations, and to receive SSI, SSDI, Medicaid, and Medicare. On the other hand, participants with equal to or more than $500.00 weekly earnings were more likely to be White, to have higher education levels than an associate degree, and to have professional and managerial occupations and were less likely to receive SSI, SSDI, Medicaid, and Medicare. In addition, they were more likely to receive assessment, VR counseling and guidance, college or university training, job search assistance, transportation, maintenance, and information and referral services compared to those with less than $200.00 weekly earnings. Implications for practice and suggestions for future research are discussed. / text

Transmission rates of HIV-1 and the mortality rate in high risk infants exposed to HIV, in the PMTCT programme, at the Neonatal Unit, of King Edward VIII Hospital , Durban, South Africa.

Nair, Nadia. January 2012 (has links)
Introduction. Previous studies have established that infants born to mothers with advanced HIV disease and co-infections are smaller, premature and have rapidly progressive HIV disease and an early death. King Edward VIIIth Hospital, in Durban, admits many sick mothers and manages a large proportion of low birth weight and ill newborns. On discharge and follow-up, the mortality and morbidity of these infants are known to be high and are related to the prematurity. How much is related to being HIV exposed is still uncertain. Aim. To determine the perinatal transmission rate of HIV-1 and mortality at 12 months in HIV exposed infants that were admitted to and discharged from the Neonatal Unit, in Durban, South Africa. Methods. In this observational study, data from the outpatient charts of HIV exposed infants that required specialised neonatal care and subsequent follow up, between the period November 2007 and December 2009, were collected. Perinatal transmission rates and mortality of these infants were compared with maternal and infant risk factors. Results. Data on 463 HIV exposed, predominantly low birth weight infants are presented. The median maternal CD4 count was 309cells/mm3 with 16.8% of mothers commenced on HAART. Maternal co-infection with TB was found in 19.2% of the cohort. Early HIV transmission occurred in 11.5% of infants and was influenced by the type of ARV exposure (None, 20%; single dose NVP, 14.3%; dual therapy, 10.6%; maternal HAART, 8.5%). The dual therapy regimen for 7 days was more protective than that for 28 days (p=0.045). HIV infection was associated with higher risk of neonatal sepsis (RR 1.6; 95% CI, 1.1-2.3; p=0.015). The mortality for the cohort at 12 months was 10%. Maternal HAART was associated with a lower mortality: 2.95% vs.10.2% (RR 3.0; 95% CI, 0.4-20.5). There was a higher mortality rate in those that were low birth weight (RR 4.2; 95% CI, 1.02-18.8; p=0.037); those that were HIV infected (RR 4.8; 95% CI, 1.9-11.6; p=0.002) and those that were breastfeeding compared to formula feeding (RR 2.7; 95% CI, 1.1-6.8; p=0.038). Discussion. Rates of HIV transmission within the PMTCT programme were similar to that reported by the Department of Health. Early maternal ARVs for PMTCT prophylaxis, prevents HIV transmission. The coverage of maternal HAART was sub-optimal. Breastfeeding was associated with a higher HIV transmission rate and was most likely associated with non-exclusive breastfeeding during neonatal admission. Recommendations. Maternal HAART or ARV prophylaxis should be commenced early in the pregnancy for the best benefits. Meticulous attention should be paid to the feeding practices of high risk HIV exposed infants admitted for specialised neonatal care. / Thesis (M.Med.)-University of KwaZulu-Natal, Durban, 2012.
