The impact of pneumonia in human immunodeficiency virus (HIV-1) infected pregnant women on perinatal and early infant mortality.

January 2007 (has links)
Background: Although the prevalence of pneumonia in pregnancy is reported to be less than 1%, the pregnant state and risk factors associated with the development of pneumonia adversely influence the outcome of pregnancy. KwaZulu-Natal is at the epicenter of the dual epidemics of tuberculosis and HIV-1 and the impact of these diseases occurring concurrently in pregnant women at King Edward VIII hospital (KEH), South Africa have been described previously. The impact of antenatal pneumonia in HIV-1 infected and uninfected women however has not been described in the study population and was investigated. Methods: Pregnant women with clinical and radiological evidence of pneumonia were recruited from the antenatal clinic and labour ward at KEH. The study was conducted prospectively between January and December 2000. The clinical profile of these women and the causative organisms were determined. In addition the impact of HIV-1 infection, maternal immunosuppression and maternal pneumonia on obstetric and perinatal outcomes were evaluated. Mothers diagnosed with tuberculosis and multi drug resistant tuberculosis were hospitalised at King George V hospital until delivery. Results: Twenty nine women were diagnosed with antenatal pneumonia (study arm) with Mycobacterium tuberculosis the only causative organism isolated. A control arm of 112 pregnant women was also studied. Maternal and perinatal mortality was restricted to the study arm with a maternal mortality ratio of 99 per 100 000 live births and a perinatal mortality rate of 240 per 1000 births. Pneumonia was significantly associated with a negative overall obstetric outcome in the presence of HIV- l infection, antenatal care, anaemia and second trimester booking status. In addition, the presence of pneumonia was significantly associated with maternal mortality. There was a highly significant association between exposure to pneumonia and poor neonatal outcome. Maternal pneumonia, maternal HIV infection and the presence of medical and obstetric conditions were significantly associated with low birth weight and neonatal pneumonia. Further, maternal pneumonia (p <0.001) and concurrent HIV infection (p=0.002) was significantly associated with neonatal death. Conclusion: The presence of pneumonia in the antenatal period impacts negatively on maternal and neonatal morbidity and mortality. Health care providers must maintain a high degree of suspicion when managing a pregnant woman with unresolving upper respiratory tract symptoms and refer timeously for further investigation. Pneumonia and in particular pulmonary tuberculosis associated with HIV co- infection in pregnancy is a threat to mother and baby. Therefore in areas endemic for TB and HIV infection, it may be prudent to screen HIV positive pregnant women for symptoms suggestive of pneumonia and thereby identify women requiring further investigations such as sputummicroscopy and cultures, and a screening chest radiograph. / Thesis (M.Med.Sc.)-University of KwaZulu-Natal, Durban, 2007.

The perceptions of community members regarding reasons why HIV prevalence rate is high in Zambezi Region than in the other thirteen regions of Namibia

Mbuche, Joseph Kasu 12 1900 (has links)
Thesis (MPhil)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: Republic of Namibia situated at the South West of Africa near Atlantic Ocean is a country in Sub-Saharan Africa region. It was divided into fourteen political administrative regions during the delimitation committee of 2013. Namibia has a population of 3 million according to the census report of 2011 (Census report 2011). The prevalence rate of HIV in Zambezi Region is higher than in other thirteen regions of Namibia. Zambezi Region is geographically located between the four SADC countries such as Zambia, Angola, Botswana and Zimbabwe. Trans–Caprivi high way is believed to contribute to the high prevalence rate of 37.7 % according to the sentinel survey report of pregnant women of 2012.The traditional beliefs and customs are affecting HIV/AIDS programmes that are implemented in the region by stakeholders and the Ministry of Health and Social Services. Namibia as a country since 1992 to 2014 has conducted sentinel surveys among pregnant women and National testing days from 2008 to find out how to address HIV and AIDS epidemic in the country. Zambezi Region according to the sentinel survey reports has the highest HIV prevalence rate among pregnant women than the other thirteen regions. The reasons that are causing the high prevalence rate of HIV in this part of the country are not yet know to the citizens. The researcher in this research has used the qualitative approach method, to investigate the perceptions of community members regarding reasons of higher HIV prevalence rate in Zambezi Region. Sampling was conducted using purposive sampling in all six constituencies of the region in which 30 participants of 15 females and 15 males were interviewed. The semi - structured interview qualitative method was used to collect data from respondents. This study is the eye opener as the reasons that are contributing to the high HIV prevalence rate in Zambezi Region have been discovered. / AFRIKAANSE OPSOMMING: Nie beskikbaar

Reasons for post-conception human immunodeficiency virus (HIV) testing among pregnant women in Gaborone, Botswana

Motseotsile, Baitlhatswi Gaolatlhe 07 October 2014 (has links)
M.Cur. (Midwifery and Neonatal Nursing Care) / Free voluntary counselling and testing (VeT) for Human Immunodeficiency Virus (HIV) by the international community and many African states is the entry point into HIV and Acquired Immunodeficiency Syndrome (AIDS) prevention, care, treatment and support. It is therefore worrisome that despite the Botswana government' multiple HIV preventative strategies, of the 56% Batswana who tested for HIV in 2008, only 34% know their status (National AIDS Coordinating Agency, Central Statistics Office & Ministry of Health, 2009:4). Among those who were tested, women outnumbered men, but even these women only had their HIV-status tested when they were already pregnant or when one of their children was suspected to have contracted AIDS, an observation that Hamblin and Reid (1991:4) has made years ago. Ethical standards were followed to conduct a study, the purpose of which was to explore and describe the reasons why women in Gaborone only volunteered to go for vcr of HIV when they were already pregnant, instead ofdoing so before they conceived. An exploratory, descriptive, qualitative and contextual design was used. Participants who met the sampling criteria were interviewed and data was audio-taped before transcription and analysis. An independent coder was involved to confirm the themes and sub-themes before relevant literature was searched. Strategies of trustworthiness were adhered to in the study (Lincoln & Guba, 1985:289-331). Findings revealed that the most significant reason for participants not testing for HIV prior to pregnancy was fear of consequences of an HIV-positive result, such as stigma and discrimination against them by their partners, families and communities should they test HIV-positive, Another reason was the socio-cultural beliefs, norms and values expressed in different forms. However, once they fell pregnant, they had themselves tested because their fear of losing their babies to HIV overruled their fear ofbeing ostracised by anybody else. Based on the findings, guidelines were formulated to assist midwives and HIV and AIDS counsellors to facilitate uptake of vcr of HIV prior to pregnancy among childbearing women and men from as young as +-15 years. Conclusions were drawn and recommendations made concerning midwifery practice, education and possible further research on this topic on a larger scale.

HIV-positive women's experience of being pregnant: a phenomenological enquiry

Schroder, Hermiena Anna 04 May 2009 (has links)
M.A. / This study explores the experience of pregnancy from the perspective of HIV-positive women. To shed light on this phenomenon, the existing literature was examined and it was found that very few studies have investigated South African women’s experience in this context. Existing findings tend to focus on the day-to-day impact of HIV on a woman’s mothering role rather than on her experience of pregnancy in particular. Pregnancy can be viewed as a process of growth, during which the relationship between the mother and her baby is prepared. For most women, acceptance of pregnancy is associated with the development of an attachment to the foetus. However, the nature of emotional support received during pregnancy can affect the development of the mothers’ attachment to the baby. Moreover, a pregnancy experience is coloured by a complex of personal needs and expectations, health status, as well as emotional, psychosocial and physical circumstances. In this regard, an HIV-positive status may influence an expectant woman’s perception of her health. Generally, being HIV positive and physically healthy is experienced as a complex psychological state, where a chronic sense of uncertainty can precipitate various somatic and psychological symptoms of distress. HIV-positive individuals who experience the most distress tend to have difficulty with initiating contact with sources of support. The focal point of this study was to understand the psychological implications of pregnancy delineated by an HIV-infection, as well as the meanings that these mothers attribute to the experience. Accordingly, a phenomenological framework was adopted to investigate the lived world of the HIV-positive pregnant woman. Phenomenologically informed interviews were conducted with HIV-positive women in the last trimester of their pregnancies, with the aim of obtaining an in-depth account of their experience of pregnancy. These women all knew about their HIV status for at least three years before falling pregnant. The interviews of three of the four participants were transcribed, followed by analyses and descriptions that were guided by phenomenological principles. The findings offer a phenomenological description of themes that form part of the phenomenon of pregnancy in the face of an HIV-positive status for these women. Their experience of pregnancy was characterized by significant emotional distress fuelled by fear of disclosing their status to their children and health care staff, uncertainty about the future, as well as having significant worry about their own and the baby’s health. These mothers adopted a cautious, wait-and-see attitude toward the pregnancy and they coped by distancing themselves from negative affect. Because they did not want to burden their families, they carried much of their emotional distress on their own. HIV-positive pregnant mothers seem to be proactive in looking after their health, possibly as a result of antenatal care. However, they are vigilant about physical changes as well as markers of health, such as CD4 counts, and shifts can be anxiety provoking. Finally, pregnancy intendedness forms a significant part of the overall experience, where a pregnant mother may consider termination of an unexpected pregnancy on the grounds of her HIV-positive status. Negotiating the decision or ability to terminate, can also have an influence on the overall experience of the pregnancy. In conclusion, an overview of the findings leads to tentative recommendations that may alleviate the emotional difficulties experienced by HIV-positive pregnant women. These findings need to be viewed in conjunction with the evaluation of the strengths and limitations. Although this study has yielded some findings that can contribute toward a deeper understanding of HIV-positive women’s experience of their pregnancies, a number of additional issues have arisen as a result of these findings. There is thus a need for further research on the topic and to this end, some suggestions for future research are offered.

Prevention of mother to child transmission (PMTCT) of HIV/AIDS: a review of using PMTCT services in South Africa

Jumare, Fadila January 2012 (has links)
Despite good intentions and commitment from health providers, it is difficult for HIV positive pregnant women to access Prevention of Mother to Child Transmission of HIV (PMTCT) services (Skinner et al 2005:115). The aim of this research was to find out the extent to which socio-economic and cultural factors influence access to and utilization of PMTCT services. It appeared that despite having a legal plan and framework to ensure that PMTCT services are available and free, the realities confronting HIV positive women in South Africa as suggested by the literature contradicted this objective. Inevitably, these contradictions were identified as some of the main factors contributing to lack of access and inadequate utilization of PMTCT services. These factors were identified through a review of fifteen studies selected based on their relevance to the research aim. The findings were presented according to the following themes: Functioning of clinics, adherence to ART, uptake of VCT and infant feeding practices. According to research evidence, the major socio-cultural factors influencing access and utilization of PMTCT services include fear of stigma and discrimination which are related to cultural norms and practices. The socio-economic factors include transport costs, lack of food, medicines and formula milk which are all related to poverty and unemployment. The research also found that health system constraints such as long waiting times in clinics, stock-outs of formula milk, medicines and test kits influenced the utilization of PMTCT services by HIV positive women.

Postnatal women's experiences of the prevention of mother-to-child transmittion of HIV programme

Links, Nomvuyiseko January 2007 (has links)
This research study endeavoured to explore and describe the experiences of women who participated in the Prevention of Mother-To-Child Transmission (PMTCT) of HIV Programme. Data relating to evaluation of the PMTCT Programme in the piloted sites compiled by other researchers in the Department of Health focus on the process, progress and extent of service implementation. There appears to be a dearth of information available from women participants in the PMTCT Programme. The objectives of the study were to: · Explore and describe postnatal women’s experiences of the PMTCT Programme offered in the East London Hospital Complex. · Propose recommendations into the existing guidelines for midwives who implement the PMTCT Programme in the health services to ensure optimal implementation of this programme. The research population included postnatal women who participated in the PMTCT of HIV Programme at the East London Hospital Complex (Frere site). Permission to conduct the research was obtained from the Eastern Cape Department of Health Ethics Committee, Chief Executive Officer of the hospital complex and the Advanced Degrees Committee and Human Ethics Committee at the Nelson Mandela Metropolitan University. The research study was qualitative, exploratory, descriptive and contextual in design. Data collection was carried out by face-to-face semi-structured interviews with postnatal women at the East London Hospital Complex (Frere site). The tape-recorded interviews were transcribed verbatim with the aid of field notes. Data analysis was done according to Tesch’s method of data analysis (in De Vos et al, 2000:343). Themes were identified from the transcriptions and finalised after consensus discussions with an independent coder who was experienced in qualitative research. Literature control, guided by the themes identified in the interviews, was carried out to compare and verify the findings of the study. Three major themes with sub-themes were identified during data analysis. The major themes were identified as follows: · The participants expressed feelings of being devastated by the results that confirmed their HIV positive status. · The participants expressed a thirst for knowledge on how to live with the diagnosis and on how to continue with the PMTCT Programme. · The physical environment where counselling and testing were done, as well as the practical arrangements, were not conducive to the full implementation of the PMTCT Programme at the antenatal clinic. Conclusions were drawn and recommendations were made in the form of additional guidelines for midwives implementing the PMTCT Programme in the antenatal clinic health services. Guidelines for further midwifery-related research were formulated.

Evaluation of a quality improvement cycle intervention in the provision of PMTCT at a regional hospital

Van Niekerk, Elizabeth C 12 1900 (has links)
Thesis (MMed)-- Stellenbosch University, 2013. / ENGLISH ABSTRACT: The vast majority of new Human Immunodeficiency Virus (HIV) infections in infants and young children occur through mother-to-child-transmission (MTCT), either during pregnancy, labour or delivery or by breastfeeding. Without access to perinatal MTCT (PMTCT) programmes approximately 30% of all babies born annually will be infected with HIV. OBJECTIVES The aim was to implement and audit a quality improvement cycle at the Worcester Obstetric Unit, which comprises of Worcester Hospital, a regional hospital in the Western Cape Province and its level one midwife obstetric Unit (MOU), in order to improve the quality of the PMTCT programme. The intervention included the implementation of easy changes and tools in the Antenatal Clinic, Infectious Diseases Clinic and Labour ward. METHODS The files and antenatal records of all HIV positive patients and patients with an unknown HIV status, who delivered at the Worcester Obstetric Unit during January, February and March of 2010 and 2011, were reviewed. All HIV negative patients and patients that had stillbirths and miscarriages were excluded. The pre-interventional findings of 2010 were compared with the post-interventional findings of 2011. RESULTS At the Worcester Obstetric Unit, for the study time period, there were 907 deliveries in 2010, of which 102 (11.2%) patients were HIV positive and 4 (0.4%) had an unknown HIV status compared to 2011, with 865 deliveries of which 108(12.5%) patients were HIV positive and no patients had an unknown HIV status. Significantly more patients were diagnosed with HIV before they fell pregnant than during pregnancy in the 2011 group, when compared with the 2010 group. A CD4 count was done on 94% of patients who were newly diagnosed with HIV and those with an unknown CD4 count result in the 2010 group, compared to 92% in 2011. There was a significant improvement after the intervention in the time it took from when blood was drawn for a CD4 count until the result was followed up, the median time decreased from 34 to 8 days (p=0.000001). Significantly more patients qualified for highly active antiretroviral therapy (HAART) after the guidelines were changed and the CD4 cut off was increased to 350 cells/l (p=0.001). Prior the intervention 18 patients did not receive the correct management before delivery due to preventable reasons, compared to one at the MOU. After the intervention this decreased significantly to only one patient at Worcester Hospital and none at the MOU (p=0.000001). Before the intervention adherence to the PMTCT protocol at the MOU was significantly better than at the hospital (p=0.0005) and after the intervention there was no significant difference (p=1.0). CONCLUSION Although the audit and quality improvement cycle was performed at a single hospital, with specific changes geared towards their needs, the basic principles can be applied to any Unit in the country providing a PMTCT service. Educating staff, creating awareness and reminding staff of the basic principles of PMTCT, implementing small changes and streamlining processes and setting specific goals or timelines, can lead to significant improvements in care, which ultimately will lead to a decrease in PMTCT of HIV and HIV related maternal and infant morbidity and mortality. / AFRIKAANSE OPSOMMING: Die oorgrote meerderheid (>90%) van nuwe Menslike Immuniteitsgebreksvirus (MIV) infeksies in babas en jong kinders vind plaas deur middel van moeder-na-kind-oordrag, hetsy gedurende swangerskap, die kraamproses of borsvoeding. Sonder toegang tot perinatale voorkomingsprogramme (PMTCT) sal ongeveer 30% van alle babas jaarliks met MIV geïnfekteer word. DOELWITTE Die doel van die studie was om ‘n gehalteverbeteringsiklus by die Worcester Verloskunde Eenheid, wat bestaan uit Worcester Hospitaal, 'n streekshospitaal in die Wes-Kaapprovinsie en sy vlak een vroedvrou verlossingseenheid (VVE), te implementer en daarna te oudit, om sodoende die gehalte van die PMTCT-program te verbeter. Die intervensie het bestaan uit die implementering van eenvoudige veranderinge en prosesse in die voorgeboortekliniek, infeksiesiekte-kliniek en kraamsaal. METODES Die lêers en voorgeboorte rekords van alle MIV-positiewe pasiënte en pasiënte met 'n onbekende MIV-status, wat gedurende Januarie, Februarie en Maart van 2010 en 2011 verlos het by die Worcester Verloskunde Eenheid, is nagegaan. Alle MIV-negatiewe pasiënte en pasiënte met doodgebore babas en miskrame is uitgesluit. Die pre-intervensie bevindings van 2010 is vergelyk met die post-intervensie bevindings van 2011. RESULTATE By die Worcester Verloskunde Eenheid was daar 907 geboortes gedurende die studietydperk in 2010, waarvan 102 (11,2%) pasiënte MIV-positief was en 4 (0,4%) met ‘n onbekende MIV-status. In 2011 was daar 865 geboortes waarvan 108 (12,5%) pasiënte MIV-positief was en geen met 'n onbekende MIV-status. In die 2011-groep is beduidend meer pasiënte gediagnoseer met MIV voor as tydens swangerskap. In die 2010-groep is daar 'n CD4-telling gedoen vir 94% van nuut gediagnoseerde pasiënte en diegene met 'n onbekende CD4-telling, in vergelyking met 92% in 2011. Daar was 'n beduidende verbetering na die intervensie in die tyd wat dit geneem het vandat bloed getrek is vir 'n CD4-telling totdat die resultaat opgevolg is. Die mediane tyd het verminder vanaf 34 na 8 dae (p = 0.000001). Nadat die riglyne vir kwalifisering vir hoogs aktiewe antiretrovirale terapie (HAART) verander is na ‘n CD4 telling 350 selle/l het daar beduidend meer pasiënte gekwalifiseer vir HAART. By Worcester Hospitaal het 18 pasiënte voor die intervensie nie die korrekte behandeling intrapartum ontvang nie weens voorkombare redes, in vergelyking met slegs een pasiënt by die VVE. Na die intervensie was daar ‘n beduidende afname na slegs een pasiënt by Worcester Hospitaal en geen by die MOU (p = 0.000001). Voor die intervensie was die korrekte uitvoering van die PMTCT-protokol by die MOU beduidend beter as by die hospitaal (p = 0,0005) en na die intervensie was daar geen beduidende verskil (p = 1.0). GEVOLGTREKKING Alhoewel die oudit en gehalteverbeteringsiklus uitgevoer is by 'n enkele hospitaal, met spesifieke veranderinge gerig tot hul behoeftes, kan die basiese beginsels toegepas word in enige eenheid in die land wat ‘n PMTCT diens verskaf. Opvoeding van personeel en bewusmaking rakende die basiese beginsels van PMTCT, klein veranderinge en die vaartbelyning van prosesse by die voorgeboorte klinieke en die stel van spesifieke doelwitte of tydlyne, kan lei tot aansienlike verbeteringe in pasiënte sorg. Dit sal uiteindelik lei tot 'n afname in die MIV oordrag van moeder na kind, asook MIV-verwante morbiditeit en mortaliteit in moeders en kinders.

The use of probiotics in the management of necrotising enterocolitis in HIV exposed premature and very-low birth weight infants

Van Niekerk, Evette 12 1900 (has links)
Thesis (PhD)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: Introduction: An association between maternal human immunodeficiency virus (HIV) infection and Necrotizing Enterocolitis (NEC) in preterm infants has been reported. The impact of probiotics in an HIV-exposed very low birth weight (VLBW) infant on the occurrence of NEC is uncertain at present; however it is known that probiotics have protective effects against inflammation and prevent NEC. Postnatal growth restriction is a major issue in preterm, especially extremely-low-birth-weight (ELBW) infants and probiotics have been found to improve feeding tolerance in preterm infants. Human milk oligosaccharides (HMO) also known as the prebiotics of human milk, are known to have bifidogenic and anti-adhesive effects. Infants that receive human milk show a reduced incidence of NEC compared to those who receive infant formula. Very little is known about the composition of breast milk in the HIV-infected mother. Objective: The primary objective of the study was to assess the effect of probiotics on the incidence and severity of NEC in high-risk infants born to HIV-positive and HIV-negative women. The secondary objectives were to assess the effect of probiotic administration on feeding tolerance and growth outcomes of HIV-exposed but uninfected preterm infants, to describe the HMO composition of HIV-infected mothers breast milk and lastly to determine if HMO composition affects the incidence of NEC in HIV-exposed preterm very low birth weight infants. Patients and Methods: A randomized, double blind, placebo controlled trial was conducted for the period July 2011 to August 2012. HIV-exposed and HIV-unexposed premature (<34 weeks gestation) infants with a birth weight of ≥500g and ≤1250g were randomized to receive either a probiotic or a placebo. The probiotic consisted of 1x109 CFU, L. rhamnosus GG and B. infantis per day and was administered for 28 days. NEC was graded according to Bell’s criteria. Anthropometrical parameters and daily intakes were monitored. Breats milk samples were analysed for oligosaccharide content. Results: 74 HIV-exposed and 110 HIV-unexposed infants were enrolled and randomized (mean birth-weight, 987g; mean gestational 28.7 weeks). The incidence of death and NEC did not differ significantly between the HIV-exposed and unexposed groups but a significantly higher NEC incidence was found in the control group. There was no difference in the average daily weight gain for treatment groups or HIV exposure. The HIV-exposed group achieved significantly higher z-scores for length and head circumference at day 28 than the unexposed group (p<0.01 and p=0.03, respectively). There were no differences in the incidence of any signs of feeding intolerance and abdominal distension between the groups. Our results show significantly higher absolute concentrations of 2’-fucosyllactose, laco-N-tetraose and lacto-N-fucopentaose 1 and higher relative abundance of 3’-sialyllactose, difucosyl-lacto-N-tetraose and fucosyl-disialyllacto-N-hexaose in HIV-infected compared to -uninfected Secretor women. DSLNT concentrations were significantly lower in the breast milk of mothers whose infants developed NEC compared to infants without NEC. Conclusion: Probiotic supplementation reduced the incidence of NEC in the premature infants; however results failed to show a lower incidence of NEC in HIV-exposed premature infants. Probiotic supplementation did not affect growth outcomes or the incidence of any signs of feeding intolerance in HIV-exposure. The data confirms previous reports that HIV-infected mothers have higher 3’sialyllactose milk concentrations. Most intriguing though, the data also indicates that low levels of DSLNT in the mother’s milk increase the infant’s risk for NEC, which is in accordance with results from previously published animal studies and warrants further investigation. / AFRIKAANSE OPSOMMING: Inleiding: ʼn Verwantskap tussen moederlike menslike immuniteitsgebreksvirus (MIV) en nekrotiserende enterokolitis (NEK) in premature babas is aangemeld. Die impak van probiotika in ʼn MIV-blootgestelde baie lae geboortemassa (BLGM) baba op die voorkoms van NEK is tans nog onseker, maar dit is wel bekend dat probiotika ʼn beskermende effek het teen inflammasie en die voorkoms van NEK. Nageboortelike groei beperkings is ʼn groot probleem in premature, veral ekstreme lae geboortemassa (ELGM) babas. Daar is gevind dat probiotika voeding toleransie in premature babas kan verbeter. Menslike melk oligosakkariede (MMO), ook bekend as die prebiotika van menslike melk, is bekend om bifidogeniese en anti-kleef effekte te hê. Babas wat moedersmelk ontvang toon ʼn verlaagde voorkoms van NEK in vergelyking met diegene wat baba formule melk ontvang. Baie min inligting is bekend oor die samestelling van borsmelk in die MIV-positiewe moeder. Doel: Die primêre doel van die studie was om die effek van probiotika op die voorkoms en die graad van NEK in hoë risiko babas van MIV-positiewe en MIV-negatiewe vroue te bepaal. Die sekondêre doelwitte was om die effek van probiotika op voeding verdraagsaamheid en groei uitkomste van MIV-blootgestelde, maar nie- geinfekteerde premature babas te evalueer sowel as die MMO samestelling van MIV-positiewe moeders se borsmelk te beskryf en laastens om die invloed van die MMO samestelling op die voorkoms van NEK in baie lae geboortegewig MIV-blootgestelde premature babas te beskryf. Pasiënte en Metodes: ʼn Gerandomiseerde, dubbelblinde, plasebo-beheerde studie is vir die tydperk Julie 2011 tot Augustus 2012 onderneem. MIV-blootgestelde en nie-blootgestelde premature (<34 weke) babas met 'n geboorte gewig van ≥500g en ≤1250g was ewekansig verdeel om probiotika of plasebo te ontvang. Die probiotika het bestaan uit 1x109 kolonie vormende eenhede, L. rhamnosus GG en B. infantis per dag en is toegedien vir 28 dae. NEK is gegradeer volgens Bell se kriteria. Antropometriese parameters en daaglikse inname is gemonitor. Borsmelk monsters is geanaliseer vir oligosakkaried inhoud. Resultate: 74 MIV-blootgestelde en 110 MIV-nie-blootgestelde babas is ingesluit en ewekansig ingedeel (gemiddelde geboorte gewig, 987g, gemiddelde gestasie 28,7 weke). Die voorkoms van die sterftes en NEK het nie beduidend verskil tussen die MIV-blootgestelde en nie-blootgestelde groepe nie, maar 'n beduidende verskil is gevind vir NEK voorkoms tussen die studie en die kontrole groep. Daar was geen verskil in die gemiddelde daaglikse gewigstoename tussen die behandelings groepe of MIV-blootstelling nie. Die MIV-blootgestelde groep het beduidend hoër z-tellings vir lengte en kopomtrek op dag 28 getoon teenoor die nie-blootgestelde groep (p <0.01 en p = 0,03, onderskeidelik). Daar was geen verskille in die voorkoms van voeding onverdraagsaamheid en abdominale distensie tussen die twee groepe nie. Ons resultate dui op aansienlik hoër absolute konsentrasies van 2'-fucosyllactose, laco-N-tetraose en lakto-N-fucopentaose 1 en hoër relatiewe voorkoms van 3'-sialyllactose, difucosyl-lakto-N-tetraose en fucosyl-disialyllacto-N-hexaose in MIV-positiewe vroue in vergelyking met-negatiewe Sekretor vroue. DSLNT konsentrasies was aansienlik laer in die melk van moeders wie se babas NEK ontwikkel het in vergelyking met babas sonder NEK. Gevolgtrekking: Probiotika aanvullings verminder die voorkoms van NEK in premature babas, maar die resultate kon nie ʼn laer voorkoms van NEK in MIV-blootgestelde premature babas bewys nie. Probiotiese aanvulling het geen invloed op groei uitkomste of die voorkoms van voeding onverdraagsaamheid in MIV-blootstelling getoon nie. Die data bevestig vorige verslae wat aandui dat MIV-besmette moeders hoër 3'sialyllactose borsmelk konsentrasies het. ʼn Interessante aspek is dat lae vlakke van DSLNT in die moeder se melk beduidend is van ʼn verhoogde risiko vir NEK, wat in ooreenstemming is met die resultate uit voorheen gepubliseerde dier studies en regverdig verdere ondersoeke.

A retrospective clinical chart review study on the core PMTCT activities at a regional hospital in Durban, KwaZulu-Natal .

Ngidi, Wilbroda Hlolisile. January 2011 (has links)
Background: Despite years of implementation, the program for PMTCT is not reaching the HIV positive pregnant women. Poor documentation as well as poor monitoring and evaluation for the program has contributed to the poor performance. This has led to South Africa being one of the 12 countries in the world with an increasing child mortality rate which is related to HIV/AIDS. Multi-steps and the complexity of the program and poor documentation have resulted in gaps in the provision of care. Objective: The aim of the study was to assess the documentation of the core activities of Prevention of Mother-to-Child Transmission of HIV program provided to pregnant women from antenatal, maternity and post-natal care at a selected Regional hospital in Ethekwini District. Methods: A non-experimental retrospective descriptive exploratory design informs the study. Provides a description of whether the activities of PMTCT are perfomed through the use of documented activities on patient’s charts. A data extraction tool was used to extract information, with the demographic information as well as the key activities of PMTCT. One hundred and thirty charts of women who had delivered in the hospital of study were sampled. Results: The study revealed gaps in the documentation of some activities, with dual therapy initiated at antenatal clinic documented to be n=98(75%), whilst NVP to the baby was 105/130 (80%). The results are in contrast with Horwood’s (2010) study which reported 91% receiving the Nevirapine prophylaxis. Although there are children missed by the program, it is interesting to note that more babies are receiving prophylaxis compared to women receiving NVP. The cd4 count, n=78(60%) uptake, seems not to be doing well, with only n=45(35%) , which is supported by Horwood’s (2010) study that showed much improvement in the cd4 uptake (70%) compared to the study results of 60%, but less cd4 results documented were reported by Horwood (2010), showing 33% respectively. Conclusion: The National strategic Plan’s (SADOH, 2007- 2011/2013) for South Africa, as well as the global Millennium Development Goals can only be achieved if all the activities for the PMTCT are improved. Documentation of activities remains the key to improved care. / Thesis (M.N.)-University of KwaZulu-Natal, Durban, 2011.

An analysis of policy implementation on HIV and AIDS in pregnant women : a case study of Lukhanji sub-district Municipality in the Eastern Cape Province in South Africa

Sinyanya, Yoliswa January 2015 (has links)
This research was conducted with the aim to evaluate the policy interventions on HIV and AIDS in pregnant women in the Lukhanji sub district of Chris Hani District Municipality. The study would also propose policy improvement strategies towards curbing the spread of HIV and AIDS in pregnant women. In realizing these goals, the entire research process was guided by the research objectives and questions which sought to evaluate policies and strategies relevant to HIV prevalence in pregnant women. The secondary research objectives were accomplished through the review and analysis of the relevant literature and theories. Qualitative research approach was used in determining the findings and conclusions from the study. Data was collected using qualitative research methods and in this case a structured questionnaire was developed and distributed to the study participants. The Questionnaires were handed and discussed with each participant. Demographics, socioeconomic and cultural factors were considered in designing the data collection tool. These factors are known to have an impact on the prevalence of HIV. It has been shown through the study that demographic variables have an effect on HIV prevalence. Hence when considering policy interventions these should be taken into account. All the respondents were given enough time and they provided clear and comprehensive responses to the questionnaire and follow up discussions. The evaluation of the responses showed that various HIV prevention related policies are being implemented within the Lukhanji sub-district. Numerous programmes relating to HIV and AIDS, also specifically covering pregnant women are being rolled out across the sub-district. HIV prevalence in the study population is rated as average to low when comparing with the district, provincial and national statistics. Current data obtained from the study indicates that HIV prevalence stands at 17%. This finding demonstrates the heterogeneity of HIV prevalence when comparing this result with current provincial and national statistics. Evaluation of the different HIV and AIDS programmes that are aligned to provincial and national policy somehow explain the positive outcomes observed in the Lukhanji sub-district The study recommends that more work be done in reaching out to the communities using various communication channels and strategies. This could address the challenges associated with the lack of cooperation with local traditional leaders, because this has been found to have a negative impact on implementation of some programmes such as circumcision. One of the positive findings from the study is the accessibility of health care facilities to the local rural communities. Further research on the subject should be undertaken to ensure continuous evaluation as this topic is viewed as a continuous global issue.
