Submitted in fulfilment of the requirements of the Degree of Master of Technology: Biomedical Technology, Durban University of Technology, 2013. / The purpose of the study was to evaluate knowledge and effects of Haemolytic Disease of the Newborn (HDN) in postnatal women from the Umgungundlovu District. Although the prevalence of HDN has declined because of prophylaxis from 45 cases per 10,000 births to 10.2 cases per 10,000 births but it is still a cause of infant and neonatal morbidity and mortality. The effects of the disease range from jaundice, kernicterus and in severe cases death. Methodology : An interviewer-administered questionnaire was used to obtain information about the knowledge and effects of HDN amongst postnatal women. The incidence rate was calculated using the number of cases that were found divided by the total number of deliveries during the study period. A total of 300 women were interviewed. SPSS version 19.0 was used to analyse data. Findings : Fifteen (15) of the 300 women had babies with confirmed HDN and only four of the 15 (26%) women had knowledge of HDN. Two hundred and eighty five women had babies with jaundice but were not affected by HDN and, of these women, 12 (4.2%) of them knew what HDN was. Overall, only 16 (5.3%) knew what HDN was. All 15 women who had babies with HDN indicated financial and emotional effects because of HDN. The total incidence was 0.09% for the first 12 months of the study period. Conclusion : Postnatal women with jaundiced babies lack knowledge of HDN and HDN has financial and emotional effects on these women. Although the incidence rate of HDN was found to be even smaller than previously reported, it still exists and threatens the lives of infants and neonates.

The purpose of the research was to determine the underlying contributory factors in an obstetric unit at the district hospital in Mpumalanga province, South Africa, regarding neonatal deaths and to propose strategies for midwifery practice. Quantitative, nonexperimental, descriptive, exploratory and retrospective (ex-post facto) design was used to explore and describe the factors contributing to neonatal deaths. Data collection was done using an audit tool. The conclusions drawn from this study supported the assumptions that there are factors related to antenatal, intrapartum, postnatal and neonatal care that contribute to neonatal deaths, thus emphasizing the urgency of improving the care of pregnant mothers and their babies through effective implementation of programmes and protocols / Health Studies / M.A. (Health Studies)

Thesis (MPhil)--University of Stellenbosch, 2004. / ENGLISH ABSTRACT: This thesis discusses the value of medical futility as an action guide for neonatal endof- life decisions. The concept is contextualized within the narrative of medical progress, the uncertainty of medical prognostication and the difficulty of just resource allocation, within the unique African situation where children are worse off today than they were at the beginning of the last century. parties actively engage in an interactive deliberation for a plan of action. Both parties ought to accept moral responsibility. Such a model of deliberation has the added advantage of transcending the limitations of the participants to arrive at a higher-level solution, which is considered more than just a consensus. It has been argued that medical progress has obscured the basic need for human compassion for the dying and for their loved ones. The literature furthermore reports that the quality of end-of-life care is unsatisfactory for both patients and their families. It is within this context that the concept of medical futility is positioned as a useful action guide. As we do not have the luxury of withdrawing from the responsibility to engage in the deliberation of end-of-life decisions, such responsibility demands an increasing awareness of ethical dilemmas and a model of medical training where communication, conflict-resolution, inclusive history taking, with assessment of patient values and preferences, is focussed on. The capacity for empathetic care has to be emphasized as an integral part of such approach. Finally, in this thesis, the concept of medical futility is tested and applied to clinical case scenarios. It is argued that the traditional medical paradigm, with its justification of an 'all out war' against disease and death, in order to achieve utopia for all, is outdated. Death in the neonatal intensive care unit is increasingly attributed to end-of-life decisions. Futile treatment could be considered a waste of scarce resources, contradicting the principle of nonmaleficence and justice, particularly in an African context. The ongoing confidence in, and uncritical submission to the technological progress in medicine is understood as a defence and coping mechanism against the backdrop of the experience of life's fragility, suffering and the inevitability of death. Such uncritical acceptance of the technological imperative could lead to a harmful fallacy that cure is effected by prolonging life at all cost. What actually occurs, instead, is the prolongation of the dying process, increasing suffering for all parties involved. The historical development of the concept of medical futility is discussed, highlighting its applicability to the paradigmatic scenario of cardio-pulmonary resuscitation. Particular attention is given to ways in which the concept could endanger patient-autonomy by allowing physicians to make unilateral, paternalistic decisions. It is argued that the informative model of the patient-physician relationship, where the physician's role is to disclose information in order for the patient to indicate her preferences, ought to be replaced by a more adequate deliberative model, where both / AFRIKAANSE OPSOMMING: Hierdie tesis bespreek die waarde van mediese futiliteit as 'n maatstaf vir aksie in gevalle van neonatale 'einde-van-lewe' besluite. Die konsep word gekontekstualiseer binne die wêreldbeskouing van mediese vooruitgang, die onsekerheid van mediese prognostikering en die probleme wat geassosieer IS met regverdige hulpbrontoekenning; spesifiek binne die unieke Afrika-situasie. Dit word aangevoer dat die tradisionele mediese paradigma, met regverdiging vir voorkoming van siekte en dood ten alle koste, verouderd is. Sterftes in neonatale intensiewe sorgeenhede word toenemend toegeskryf aan 'einde-van-lewe' besluite Futiele behandeling sou dus beskou kon word as 'n vermorsing van skaars hulpbronne, wat teenstrydig sou wees met die beginsels nie-skadelikheid ('nonmaleficence') en regverdigheid. Die volgehoue vertroue in en onkritiese aanvaarding van aansprake op tegnologiese vooruitgang lil geneeskunde, kan beskou word as verdediging- en hanteringsmeganisme in die belewenis van lewenskwesbaarheid, lyding en die onafwendbaarheid van die dood. Sodanige onkritiese aanvaarding van die tegnologiese imperatief kan tot 'n onverantwoordbare denkfout, naamlik dat genesing plaasvind deur verlenging van lewe ten alle koste, lei. Wat hierteenoor eerder mag plaasvind, is 'n verlenging die sterwensproses en, gepaard daarmee, toenemende lyding van all betrokke partye. Die historiese ontwikkeling van die konsep van mediese futiliteit word bespreek met klem op die toepaslikheid daarvan op die paradigmatiese situasie van kardiopulmonêre resussitasie. Spesifieke aandag word gegee aan maniere waarop die konsep pasiënte se outonomie in gevaar stel, deur die betrokke medici die reg te gee tot eensydige, paternalistiese besluitneming. Die argument is dan dat die informatiewe model, waar die verhouding tussen die dokter en pasiënt gebasseer is op die beginsel dat die dokter inligting moet verskaf aan die pasiënt sodat die pasiënt 'n ingeligte besluit kan neem, vervang moet word met 'n meer toepaslike beraadslagende model, waar sowel die dokter as die pasiënt aktief deelneem aan interaktiewe beraadslaging oor 'n aksieplan. Albei partye word dan moreel verantwoordbaar. So 'n model van beraadslaging het die bykomende voordeel dat dit die beperkings van die deelnemers kan transendeer. Sodoende word 'n hoër-vlak oplossing - iets meer as 'n blote consensus - te weeg gebring. Die argument word ontwikkel dat mediese vooruitgang meelewing met die sterwendes en hul geliefdes mag verberg. Verder dui die literatuur daarop dat die kwaliteit van einde-van-lewe-sorg vir sowel die pasiënte as hul familie onaanvaarbaar is. Dit is binne hierdie konteks dat die konsep van mediese futiliteit kan dien as 'n maatstaf vir aksie. Medici kan nie verantwoordelikheid vir deelname aan beraadslaging rondom eindevan- lewe beluitneming vermy nie, en as sodanig vereis die situasie toenemende bewustheid van sowel die etiese dilemmas as 'n mediese opleidingsmodel waann kommunikasie, konflikhantering, omvattende geskiedenis-neming, met insluiting van die pasient se waardes en voorkeure, beklemtoon word. Die kapasiteit vir empatiese sorg moet weer eens beklemtoon word as 'n integrale deel van hierdie benadering. Ten slotte, hierdie tesis poog om die konsep van mediese futiliteit te toets en toe te pas op kliniese situasies.

D.Cur. / The purpose of this study was to formulate clinical guidelines for critical nursing actions in a neonatal intensive care unit (NICU). Currently each NICU has their own set of policies and standards for various procedures relevant to NICUs. There is thus no standardisation of nursing methods between the increasing numbers of NICUs. Uniform standards are of significant importance with regards to the nurses working in the units on a freelance basis through nursing agencies. The nurses often work in more than one unit and are thus subjected to various methods of performing one task ...

The Hispanic birthweight paradox, whereby Hispanic women exhibit a comparable or lower risk of bearing a low birthweight infant than their white counterparts despite relative socioeconomic disadvantage, has been observed across a number of research studies. However, the majority of evidence for the paradox has focused on Hispanics in aggregate form or on populations with primarily Mexican ancestry and has relied largely on outcome measures with important methodological shortcomings. Furthermore, studies have identified the variation of birthweight risk among Hispanics by nativity, maternal education and neighborhood composition, but the evidence has been scarce and inconsistent. The overall goal of this dissertation was to investigate the Hispanic health paradox with relation to measures of birthweight and infant size in births to women residing in New York City aged 20 years and older, using birth records for years 2003 through 2007 collected by the Office of Vital Statistics of the New York City Department of Health and Mental Hygiene (N=460,881). The main outcomes of interest in this study were mean birthweight, low birthweight (LBW, defined as < 2500 grams versus ≥ 2500 grams) and small for gestational age (SGA, calculated as the 10th percentile for birthweight at each week of gestational age and by sex). Multilevel logistic models with random effects were used to estimate odds ratios for the association between race/ethnicity and measures of birthweight and infant size, while controlling for individual-level and contextual factors and accounting for the correlation between observations within the same neighborhood. Analyses were conducted with Hispanics as an aggregate group as well as with race/ethnic-nativity subgroups. In addition, effect measure modification by maternal education and by neighborhood proportion of Hispanic population (NPHP) were examined. This research confirmed the Hispanic paradox in SGA analyses for Hispanics overall and for both U.S.-born and foreign-born Hispanics, but not in analyses with LBW or with mean birthweight. As compared to white women, black women exhibited 50% greater risk (OR:1.50;95%CI:1.45,1.55) and Hispanic women comparable risk (OR:1.03;95%CI:1.00,1.06) of having an SGA infant, in a fully adjusted model. With regard to LBW, the risk was more than double for black women (OR:2.25;95%CI:2.16,2.35) and close to 50% greater for Hispanic women (OR:1.46;95%CI:1.40,1.53) as compared to that of their white counterparts. In addition, the mean birthweight of infants born to Hispanic women was significantly lower compared to those born to white women. Furthermore, the relationship between race/ethnicity and all three measures of birthweight and infant size varied by maternal nativity status (p<0.0001), with infants of foreign-born women experiencing more favorable outcomes relative to their U.S.-born counterparts. The paradox with SGA was also apparent across most Hispanic race/ethnicity-nativity subgroups, The odds were greatest among black and Puerto Rican women overall (OR:1.52;95%CI:1.47,1.57 and OR:1.17;95%CI:1.13,1.22, respectively) and lowest among Mexican and South American women overall, (OR:0.91;95%CI:0.87,0.95 and OR:0.85;95%CI:0.80,0.89) as compared to white women in a fully adjusted model. The odds of SGA for infants born to Dominicans, Central Americans and Cubans in the fully adjusted model were similar to those born to whites. In addition, SGA varied by maternal nativity status (p<0.0001), with more favorable SGA odds observed among infants of most foreign-born women, as compared to whites. The exception was U.S.-born Puerto Ricans who consistently exhibited elevated risk of SGA relative to whites. The association of race/ethnicity-nativity with SGA varied by maternal educational attainment (p<0.0001), but the influence varied by subgroup. The observed advantage of foreign birth was stronger among less educated women of all Hispanic subgroups other than Puerto Ricans and Cubans. Similarly, the variation of SGA risk by neighborhood proportion of Hispanic population (NPHP) differed across subgroups (p<0.0001). NPHP did not appear to influence the association between race/ethnicity-nativity and SGA in a consistent pattern, but among black women and US-born Puerto Rican women greater NPHP was associated with a higher risk of SGA. Findings from this study underscore the importance of using SGA an accurate measure of infant size and of conducting analyses disaggregating race/ethnicity and nativity subgroups. Future research should focus on factors that contribute to the resilience of Hispanic subgroups in the face of adverse economic circumstances, such as the role of social support networks and acculturation. Greater understanding of the salubrious circumstances that lower the risk of adverse birth outcomes has major public health benefits, especially for a wide-ranging population of mothers, Hispanic and non-Hispanic, and their infants.

The purpose of this study was to investigate the determinants of high neonatal mortality rates in Migori County, Kenya. The neonatal mortality cases were utilised as the target population to the study. A quantitative, descriptive, cross-sectional, non-experimental research design was used. A systematic sampling technique was employed to draw a sample of 201 archived neonatal cases out of 420 neonatal mortality medical records, which constituted the study population. Data were collected by means of a developed questionnaire. The Statistical Package for Social Sciences (SPSS) Version 21 was used to analyse data. The main findings revealed the leading determinants of neonatal mortality were early neonatal period, prematurity, poor 1st Apgar score, low birth weight and neonates with intrapartum complications. Obstetrical haemorrhage and HIV were the main maternal complications associated to neonatal mortalities, while the leading direct causes of death in this study were birth asphyxia and sepsis. Other determinants were gender, rural residence, lowly educated and informally employed mothers. To reduce mortalities, a multifaceted approach is needed to establish quality improvement in neonatal intensive care, reduce preterm birth incidences, and empower mothers socio-economically. / Health Studies / M.A. (Nursing Science)

Feminist and social historians have long been interested in that particularly female ability to become pregnant and bear children. A significant body of historiography has challenged the notion that pregnancy and childbirth considered to be the acceptable and 'appropriate' roles for women for most of the twentieth century in Australia - have always been welcomed, rewarding and always fulfilling events in women's lives. Several historians have also begun the process of enlarging our knowledge of the changing cultural attitudes towards bereavement in Australia and the eschewing of the public expression of sorrow following the two World Wars; a significant contribution to scholarship which underscores the changing attitudes towards perinatal loss. It is estimated that one in four women lose a pregnancy to miscarriage, and two in one hundred late pregnancies result in stillbirth in contemporary Australia. Miscarriage, stillbirth and neonatal death are today considered by psychologists and social workers, amongst others, as potentially significant events in many women's lives, yet have received little or passing attention in historical scholarship concerned with pregnancy and motherhood. As such, this study focuses on pregnancy loss: the meaning it has been given by various groups at different times in Australia's past, and how some Australian women have made sense of their own experience of miscarriage, stillbirth or neonatal death within particular social and historical contexts. Pregnancy loss has been understood in a range of ways by different groups over the past 100 years. At the beginning of the twentieth century, when alarm was mounting over the declining birth rate, pregnancy loss was termed 'foetal wastage' by eugenicists and medical practitioners, and was seen in abstract terms as the loss of necessary future Australian citizens. By the 1970s, however, with the advent of support groups such as SANDS (Stillbirth and Neonatal Death Support) miscarriage and stillbirth were increasingly seen as the devastating loss of an individual baby, while the mother was seen as someone in need of emotional and other support. With the advent of new prenatal screening technologies in the late twentieth century, there has been a return of the idea of maternal responsibility for producing a 'successful' outcome. This project seeks to critically examines the wide range of socially constructed meanings of pregnancy loss and interrogate the arguments of those groups, such as the medical profession, religious and support groups, participating in these constructions. It will build on existing histories of motherhood, childbirth and pregnancy in Australia and, therefore, also the history of Australian women.

Gestational diabetes mellitus (GDM) and infant macrosomia are important obstetric health concerns for Aboriginal populations in Canada. Previous research in non-Aboriginal populations has established that GDM and macrosomia are associated with increased risk of fetal morbidity. Specifically, GDM is a risk factor for infant macrosomia, hypoglycemia, polycythemia, hypocalcemia, and hyperbilirubinemia. Furthermore, macrosomia is an independent risk factor for shoulder dystocia, clavicular fracture, brachial plexus injury, birth asphyxia and operative delivery. The main objectives of this study were to determine prevalence rates of GDM and macrosomia related neonatal complications for the James Bay Cree population of northern Quebec, and to identify risk factors for specific birth trauma injuries and metabolic complications in the population. The prevalence of macrosomia (≥4500 g) was 10.4%, and the estimated prevalence of GDM was 16.6% (95% CI 14.6-18.6) (n = 229/1379). Shoulder dystocia was the most common birth trauma event among the Cree, affecting 2.5% (n = 42/1650) of all Cree births, and 9.3% (n = 16/172) of macrosomic deliveries ≥4500 g. The prevalence of neonatal hypoglycemia was also high, affecting 8.8% (n = 144/1650) of all Cree newborns, and 18.1% (n = 34/192) of GDM deliveries. Macrosomia (BW ≥ 4500 g) was a significant risk factor for shoulder dystocia, clavicular fracture, hypoglycemia, and caesarean section delivery. After adjusting for maternal age, parity, and gestational age, GDM was identified as a significant risk factor for macrosomia (≥4500 g), hypoglycemia, polycythemia, and hypocalcemia. In summary, this study identified a high incidence of neonatal complications among the James Bay Cree compared with rates in the general North American population. These outcomes can be explained, in part, by high prevalence rates of gestational diabetes and infant macrosomia. Further studies to investigate the long-term consequences of GDM and

Antibiotics are among the most commonly prescribed drugs. Although the majority of these drugs were developed several decades ago, optimal dosage (dose, dosing interval and treatment duration) have still not been well defined. This thesis focuses on the development and evaluation of pharmacometric models that can be used as tools in the establishment of improved dosing strategies for novel and already clinically available antibacterial drugs. Infectious diseases are common causes of death in preterm and term newborn infants. A population pharmacokinetic (PK) model for gentamicin was developed based on data from a prospective study. Body-weight and age (gestational and post-natal age) were found to be major factors contributing to variability in gentamicin clearance and therefore important patient characteristics to consider for improved dosing regimens. A semi-mechanistic pharmacokinetic-pharmacodynamic (PKPD) model was also developed, to characterize in vitro bacterial growth and killing kinetics following exposure to six antibacterial drugs, representing a broad selection of mechanisms of action and PK as well as PD characteristics. The model performed well in describing a wide range of static and dynamic drug exposures and was easily applied to other bacterial strains and antibiotics. It is, therefore, likely to find application in early drug development programs. Dosing of antibiotics is usually based on summary endpoints such as the PK/PD indices. Predictions based on the PKPD model showed that the commonly used PK/PD indices were well identified for all investigated drugs, supporting that models based on in vitro data can be predictive of antibacterial effects observed in vivo. However, the PK/PD indices were sensitive to the study conditions and were not always consistent between patient populations. The PK/PD indices may therefore extrapolate poorly across sub-populations. A semi-mechanistic modeling approach, utilizing the type of models described here, may thus have higher predictive value in a dose optimization tailored to specific patient populations.
