A imunização materna com a vacina acelular para pertussis (dTpa) é uma intervenção adicional que visa fornecer proteção aos recém-nascidos (RN). No entanto, tem sido relatado que altos níveis de anticorpos adquiridos por transferência placentária podem afetar adversamente a resposta imune desses RN após a imunização ativa, devido ao mascaramento antigênico. Neste estudo, avaliamos a aquisição passiva neonatal de anticorpos específicos para pertussis e sua influência na resposta imune celular dos neonatos. A casuística foi composta por gestantes vacinadas com a vacina dTpa (grupo caso, n=66) ou por gestantes que não receberam a vacina (grupo controle, n=101). As concentrações de anticorpos IgG séricos específicos para Bordetella pertussis total (Bp), toxina pertussis (PT), hemaglutinina filamentosa (FHA) e pertactina (PRN) foram quantificadas em soro materno e de cordão umbilical de seu respectivo RN, e as concentrações de anticorpos IgA específicos para Bp e PT foram dosadas nas amostras de colostro por meio de ensaio imunoenzimático. A responsividade dos linfócitos do sangue neonatal foi avaliada após estimulação ex vivo com Bp inativada por citometria de fluxo com o intuito de detectar a proliferação, produção de citocinas e fenótipo de ativação dos linfócitos T em um contexto de altas concentrações de IgG específicas adquiridas após a vacinação materna. As concentrações de anticorpos IgG anti-Bp, PT, FHA e PRN foram maiores nas amostras de soro materno e de cordão umbilical do grupo caso quando comparadas ao grupo controle (p < 0,0001), com índices de correlação positivos em ambos os grupos para todos os antígenos estudados (p < 0,0001). As vacinações realizadas entre 26 e 31 semanas de gestação foram associadas com as melhores taxas de transferência placentária, embora índices significativamente menores foram detectados no grupo caso (p < 0,01). As concentrações de anticorpos IgA anti-Bp e anti-PT no colostro não foram afetadas pelo estado vacinal da parturiente. Os ensaios de cultura celular revelaram que os RN responderam ao estímulo com Bp, com maior expressão de CD40L, CD69 e proliferação de células T CD4, em comparação com células não estimuladas. Também foi observada uma menor resposta Th1, enquanto a resposta Th2 foi preservada, em comparação com os adultos, mas sem diferenças entre os grupos de neonatos em nenhum dos parâmetros estudados. Nossos resultados indicam que níveis mais altos de anticorpos IgG específicos para B. pertussis no soro dos RN após a vacinação materna não afetam a resposta imune neonatal mediada por células / Maternal immunization with pertussis acellular vaccine (Tdap) is an additional intervention that provides protection to newborns. However, it has been reported that high antibody levels acquired via placental transfer may adversely affect the immune response of newborns after active immunization due to epitope masking. In this study, we evaluated neonatal passive acquisition of pertussis-specific antibodies and their influence on the neonatal cell-mediated immune response. The sample consisted of pregnant women vaccinated with the Tdap vaccine (case group, n=66) or pregnant women who received no vaccine (control group n=101). Whole-cell Bordetella pertussis (Bp), pertussis toxin (PT), filamentous hemagglutinin (FHA) and pertactin (PRN)-specific serum IgG concentrations were quantified in paired maternal-cord sera, and Bp- and PT-specific IgA concentrations were evaluated in colostrum samples by immunoenzymatic assay. Ex vivo neonatal blood lymphocyte responsiveness after inactivated Bp stimulation was assessed using flow cytometry to detect the proliferation, cytokine production and activation phenotype of T lymphocytes in the context of high specific IgG concentrations acquired after maternal vaccination. Anti-Bp, PT, FHA and PRN IgG antibody concentrations in maternal and cord serum samples from case group were higher than those in control group (p < 0.0001), with positive correlation indexes in both groups for all pertussis antigens (p < 0.0001). Vaccinations performed between 26 and 31 gestation weeks were associated with the best placental transfer ratios, although significantly lower ratios were detected in case group (p < 0.01). Anti-Bp and anti-PT IgA concentrations in colostrum were not affected by vaccine status. Cell culture assays revealed that newborns responded to Bp stimulation with higher expression of CD40L CD69 and CD4+ T cell proliferation compared to unstimulated cells. It was also observed a lower Th1 response, while a preserved Th2 response compared to adults, but there were no differences between neonatal groups for any of the studied parameters. Our results indicate that higher pertussis-specific IgG levels in newborn sera after maternal vaccination do not affect the neonatal cell-mediated immune response

In Uganda, there are an estimated 200,000 women suffering from obstetric fistula, with 1,900 new cases expected annually. These figures, combined with a persistently high maternal mortality rate, have led to an international discourse that claims the solution to improving maternal health outcomes is facility-based delivery with a skilled birth attendant. In accord with this discourse, the Ugandan government criminalized traditional birth attendants in 2010. In this study, I examine the lived experience of traditional birth attendants and women who have suffered from an obstetric fistula in eastern Uganda. Using data collected from open-ended, semi-structured interviews, focus groups, and participant-observation, I describe the biocultural determinants of obstetric fistula. Based on findings, I argue that although emergency obstetric care is critical to prevent obstetric fistula in cases of obstructed labor, the criminalization of the locally constructed system of care, TBAs, serves as yet another layer of structural violence in the lives of rural, poor women. Results demonstrate how political-economic and cultural determinants of obstetric fistula are minimized in favor of a Western prescribed, bio-medical solution, which is heavily resource dependent. This solution is promoted through a political economy of hope fueled by the obstetric imaginary, or the enthusiastic belief in Western-style biomedical obstetric care’s ability to deliver positive health outcomes for women and infants regardless of local context and constraints. Recommendations include increased obstetric fistula treatment facilities with improved communication from medical staff, decriminalization of traditional birth attendants and renewed training programs, and engaging local populations in maternal health discourse to ensure culturally competent programs. / Graduation date: 2013

Fetal Alcohol Syndrome (FAS) is a preventable cause of mental retardation and is the severest category within Fetal Alcohol Spectrum Disorder (FASD). As gestational alcohol exposure affects fetal cognitive functioning, children with FAS present with intellectual deficits. Unfortunately FASD prevalence rates are increasing amongst infants and school-going children. The main goal of this study was to compare the neurodevelopmental subscales of infants diagnosed with FAS, Partial FAS and non- FAS. Seventy-four infants with confirmed FAS, Partial FAS or Non- FAS diagnoses were assessed using the Griffiths Mental Developmental Scale. Development assessed at 7-12 and 17-29 months of age showed that, regardless of a FAS, PFAS or Non-FAS diagnosis, all infants performed weaker at their assessment at 17-29 months. The Subscales significantly affected included Personal-Social, Eye- Hand Coordination and Performance. The infants with FAS and PFAS displayed the most marked developmental delays. From this study it can be concluded that there are definite neurodevelopmental profiles for infant's diagnosed with FAS, PFAS and/or Non-FAS, highlighting the significant impact of prenatal alcohol exposure on various aspects of infant development. / Social work / M.Diac.

The aim of the study was to determine factors contributing to late booking amongst pregnant women at Ekurhuleni health district in order to offer recommendations for enhancing early booking. Interpretative phenomenological analysis design was used. Data were collected using semi-structured individual face-to-face interviews from 20 purposively selected pregnant women. Each interview was audio recorded and lasted between 45-60 minutes. Fields notes were taken to triangulate data collection method. Audio recorded interviews were transcribed verbatim. Data were thematically analysed using Interpretative Phenomenological Analysis framework for data analysis. Results indicate that healthcare service related factors such as human resources, infrastructure and the type of service rendered at the clinic contribute to late bookings. Client related factors such as socioeconomic status, cultural beliefs and knowledge deficit also contribute to late bookings. Recommendations are made addressing both healthcare service and client related factors in order to enhance early booking among pregnant woman at Ekurhuleni district. / Health Studies / M.A. (Nursing science)

The purpose of the study is to determine the barriers to utilisation of antenatal care services among pregnant women in Omaheke Region - Namibia. A quantitative, cross-sectional descriptive research was followed, and a structured questionnaire was used to obtain information from study participants. One hundred and ten (110) women of child-bearing age between 18 to 49 years who visited Gobabis District Hospital in Omaheke Region for deliveries (full-term) or kept for postnatal care purposes were selected. A questionnaire with open-ended and closed-ended questions was designed using a Likert scale to gather information. SPSS software was used to generate descriptive statistics. Results indicated that the majority of respondents (39%) who attended antenatal care services, fell within the age range of 18-21 years. Participants demonstrated higher knowledge of the recommended number of antenatal care visits and of the importance of antenatal care services. Transport money and cost, long distances to health facilities, desirability, unplanned or unwanted pregnancy, and limited transportation options are the barriers that contribute to low utilisation of antenatal care services among pregnant women in Omaheke Region. Recommendations for deployment of more qualified midwives at rural antenatal clinics, building more antenatal care clinics in the region and creation of community awareness campaigns on the importance of antenatal care may increase the utilisation of antenatal care services in the Region. It is anticipated that this research will contribute to the promotion and utilisation of antenatal care services among pregnant women in Omaheke Region. / Health Studies / M. P. H.

The registered midwives are engaged in continuous health education lessons In antenatal visits, discouraging antenatal clients from using hannful traditional and cultural practices in an attempt to preserve pregnancy to tenn. Despite the registered midwives' efforts, the clients continue to use hannful cultural methods, which are life-threatening to both the mother and the foetus In utero. The prenatal clients perceive the registered midwives as not being sensitive to their culture. The results of this study revealed that health education in antenatal clinics should be collaborative: that is, the people who have influence over the clients' pregnancy, like me mother-in-law, the traditional practitioners, cUents and their family members, should be involved by the midwives during the preparation of pregnancy lessons and health education lessons on how to preserve pregnancy to term according to· scientifically proven methods. / Health Studies / M.A. (Health Studies)

The academic challenges faced by pregnant and nursing students in Zimbabwe do not seem to attract the attention of scholars. This study focused on the educational challenges faced by pregnant and nursing adult learners at Morgenster Teachers‟ College, a tertiary education institution. Participants‟ perceptions of the academic challenges they faced were established through the use of a qualitative methodology in which the semi-structured interview was the dominant data collection method. Non-participant observation and document analysis were employed to complement the dominant method. The findings indicated that the academic challenges faced by mothering adult learners are related to physical problems, social relationships, inadequate financial resources and administrative problems. The study revealed that such students develop strategies to alleviate some of the educational challenges they face. In view of the findings, recommendations are made to improve the learning environment of mothering students and for further research to address the problem. / M. Ed.

This study investigated the factors influencing the utilisation of PMTCT of HIV services and proposed measures to promote service utilisation by HIV positive pregnant women in the FCT, Abuja, Nigeria. Effective interventions exist that can reduce the transmission of HIV infection to the baby. The study is a quantitative descriptive one, with 190 HIV positive pregnant women from 20 health Centres in three area councils in Abuja, who were interviewed using structured questionnaire to get their opinion. The findings revealed that the majority (90.4%) of the respondents were aware of PMTCT and how HIV can be transmitted from mother-to-child. The respondents (95.9%) were of the opinion that all pregnant women should be tested. Notably, PMTCT services will be hindered by the following: permission from spouse before being tested, couple counselling not done, group post test counselling, non-incorporation of family planning and low support group enrolment. Recommendations made include emphasis on couple counselling, confidentiality and friendly environment / Health Studies / M.A. (Public Health)

In its efforts to reduce maternal mortality and prevent Mother-to-Child Transmission of HIV, the government of Swaziland developed and implemented several programmes including a special antenatal care package for HIV-positive pregnant women in line with the WHO (2009) guidelines. Since the implementation of this latest special ANC package for HIV-positive women, little is known about how these services are experienced by the intended recipients. The purpose of this study was to explore and describe the actual experiences of HIV-positive women with the antenatal care services provided at a regional referral hospital in Swaziland, with the view of providing more insight into the quality of ANC services from the users' perspectives. A qualitative descriptive, exploratory design was used to address the above purpose. The researcher used purposive sampling to select the participants who met the inclusion criteria for the study. Semi-structured individual interviews were used and saturation was reached after 18 individual face-to-face interviews. Thematic content analysis was used to analyse the collected data. Forteen themes related to the participants experiences with the ANC services and seven related to measures for improvement emerged from data. In general HIV positive pregnant women expressed positive views towards ANC services they received at the target institution. The results give an indication on the quality of the focussed ANC package provided at the hospital and specific recommendations for improvement are outlined. / Health Studies / M. A. (Nursing Science)
