Abstract Objectives.—The aims of this study were to determine and compare fetal hemoglobin (HbF) fractions at birth in newborns exposed and not exposed to selected factors that have been reported to increase the risk of sudden infant death syndrome (SIDS). Previous studies have implicated HbF in the etiology of SIDS by finding higher fractions in infants dying from SIDS compared to age-matched control infants. Design.—We performed a cross-sectional study using high-performance liquid chromatography to measure HbF fractions in newborn cord blood samples. Exposure to selected risk factors for SIDS was assessed through review of medical records. Participants.—Six hundred thirty-three infants born at Via Christi Regional Medical Center–St Francis Campus, Wichita, Kan, from February 28 through August 5, 1997. Main Outcome Measure.—Hemoglobin F fractions at birth were compared in newborns exposed and not exposed to selected risk factors associated with increased incidence of SIDS. Results.—Mean HbF fractions were significantly higher in preterm newborns of mothers who smoked and in term newborns with intrauterine growth restriction, pregnancy weight gain less than or equal to 9 kg, and pregnancy complications associated with reduced placental blood flow. An elevated newborn HbF fraction, defined as 77% or greater, was significantly associated with maternal smoking, maternal anemia, intrauterine growth restriction, and pregnancy complications associated with reduced placental blood flow. Conclusion.—This study suggests a possible mechanism (HbF) by which previously identified factors may increase the risk of SIDS.

This study of cultural beliefs and practices related to childrearing and child health among the Hmong in Melbourne, Australia, used in-depth interviews and participant observation of 27 Hmong mothers and some Hmong traditional healers between 1993 and 1998. Traditional Hmong beliefs and practices include: taking notice of the birth date and time, placing a silver necklace on the newborn, not praising the newborn, not taking the infant out during the first 30 days, breastfeeding, the infant's sharing a bed with the parents, and a soul-calling ceremony on the third day after birth. All Hmong mothers follow cultural beliefs and practices to prevent the ill-health or death of their newborn infants, but some aspects of these practices have had to be modified to suit the new living environment in Australia. Health care professionals need to acknowledge the different ways of caring for a young child among the Hmong so as to avoid misunderstandings and to provide sensitive care. Hmong beliefs and practices also have implications for health promotion campaigns and can be a valuable source of ideas in the efforts to promote infant health and reduce infant deaths in Australia and elsewhere.

In 1953, Virginia Apgar, M.D. published her proposal for a new method of evaluation of the newborn infant. The avowed purpose of this paper was to establish a simple and clear classification of newborn infants which can be used to compare the results of obstetric practices, types of maternal pain relief and the results of resuscitation. Having considered several objective signs pertaining to the condition of the infant at birth she selected five that could be evaluated and taught to the delivery room personnel without difficulty. These signs were heart rate, respiratory effort, reflex irritability, muscle tone and color. Sixty seconds after the complete birth of the baby a rating of zero, one or two was given to each sign, depending on whether it was absent or present. Virginia Apgar reviewed anesthesia records of 1025 infants born alive at Columbia Presbyterian Medical Center during the period of this report. All had been rated by her method. Infants in poor condition scored 0-2, infants in fair condition scored 3-7, while scores 8-10 were achieved by infants in good condition. The most favorable score 1 min after birth was obtained by infants delivered vaginally with the occiput the presenting part (average 8.4). Newborns delivered by version and breech extraction had the lowest score (average 6.3). Infants delivered by cesarean section were more vigorous (average score 8.0) when spinal was the method of anesthesia versus an average score of 5.0 when general anesthesia was used. Correlating the 60 s score with neonatal mortality, Virginia found that mature infants receiving 0, 1 or 2 scores had a neonatal death rate of 14%; those scoring 3, 4, 5, 6 or 7 had a death rate of 1.1%; and those in the 8-10 score group had a death rate of 0.13%. She concluded that the prognosis of an infant is excellent if he receives one of the upper three scores, and poor if one of the lowest three scores.

Objective Current guidelines for neonatal resuscitation suggest it may be reasonable to stop resuscitation after 10 minutes in infants born with no detectable heartbeat. This study describes the length of resuscitation provided in a cohort of profoundly compromised newborn infants. Study Design Chart review of a regional hospital system database of newborn infants from 2010 to 2017 with a documented 10-minute Apgar score of 0 or 1. Results From a total birth population of 49,876 infants, 172 newborns were identified. Of these, 133 infants did not receive resuscitation and died while receiving comfort care. In the 39 resuscitated infants, 15 (38%) achieved return of spontaneous circulation (ROSC) at an average of 20 minutes; 32 of these 39 newborns (82%) died within 24 hours. Average time to ROSC for survivors was 17.8 minutes. Death or severe neurologic disability at 15 to 24 months of age was present in 92% (36/39) of resuscitated infants. Conclusion Prolonged resuscitation of newborns is rare. In this cohort, 92% died or had severe neurodevelopmental disability. Infants with ROSC received 20 minutes of resuscitation. Infants with ROSC typically did not survive beyond 24 hours unless they survived to discharge. To increase the number of infants with ROSC, continuing resuscitation beyond 10 minutes may be reasonable.

Background. Newborn infants who have undergone severe birth asphyxia have a high risk of neurological disorders and death. The most effective method for the treatment of hypoxic ischemic encephalopathy caused by intrapartum asphyxia is therapeutic hypothermia, or targeted temperature management. Currently, there are no large studies comparing its different methods, therefore the aim of our study was to compare the effectiveness of device-induced and uncontrolled therapeutic hypothermia in newborn infants who underwent intrapartum asphyxia.Materials and methods. Study design: we conducted a retrospective, longitudinal, cohort study in 39 newborn infants born in severe asphyxia and receiving uncontrolled therapeutic hypothermia (group 1), and in 48 newborn infants born in severe asphyxia and receiving device-induced therapeutic hypothermia (group 2). Statistical data processing was carried out using standard techniques.Results. The body temperature in newborn infants of both groups was reduced to 33.5 °C within the first hour, but when using uncontrolled therapeutic hypothermia, the body temperature fluctuated from 32 to 35 °C. Device-induced therapeutic hypothermia has a more effective neuroprotective effect as compared to uncontrolled hypothermia (p< 0.05) and more rapidly stabilizes metabolism in newborns due to a decrease in lactate levels (p < 0.05). In newborns device-induced therapeutic hypothermia stabilizes hemodynamics more quickly compared to uncontrolled therapeutic hypothermia (p < 0.05). Device-induced therapeutic hypothermia reduces the period of hospitalization in the neonatal intensive care unit (p < 0.05), the risk of cerebral edema (p < 0.05) and of the repeated episodes of seizures (p < 0.05). Conclusion. Using uncontrolled therapeutic hypothermia causes a high risk of unintentional fluctuations in rectal temperature towards both hypothermia and rewarming, which can aggravate the severe condition of newborn infants. Device-induced therapeutic hypothermia has a more effective neuroprotective effect.

Background The prevalence and the mortality of low birthweight infants are still high. Low birth weight (LBW) births areresponsible for newborn death. LBW infants are easier to sufferserious health problems and death. Lower infant body weightand younger gestational age are determinants of greater risk ofmortality.Objective To determine the characteristics of LBW infants andtheir outcomes in Sanglah Hospital, Denpasar.Methods This prospective study was conducted on all LBWinfants in the nursery from their time of admission until dischargefor the year of 20 11..Results There were 120 LBW infants admitted to SanglahHospital fromJanuary 2011 to December 2011. The prevalenceofLBW was 8.9%. The birth weight group of 1500􀁰2499 gramshad the highest number of infants (79.2%). The gestational agegroup of 33􀁰36 weeks had 53.3% of the infants, while 68.3% ofthe LBW infants were of the appropriate gestational age. Themost common method of delivery was normal spontaneousdelivery (70%). Moderate asphyxia was observed in 25% of thesubjects, while severe asphyxia was observed in 22.5% of subjects.The mortality rate was 24.2%.Conclusions The prevalence of LBW of all newborns in ourhospital was 8.9%. Severe asphyxia was observed in 22.5% ofsubjects. The mortality rate of the LBW infants was 24.2%. OurLBW infants were most cormnonly in the categories of birth weightof 1500􀁰2499 grams, gestational age was between 33􀁰36 weeks,appropriate for gestational age, as well as delivered spontaneously.[Paediatr lndanes. 2012,52:30003].

The phenomenon of ‘unknown’ infant deaths addressed in this article was first explored in the course of research on fatalities arising from political violence during the Irish revolution of 1916–1921. Our data are derived from the General Register of Death Indices (G.R.D.I.), held in the General Register Office, Dublin, which are organised alphabetically, and which form an official record of deaths registered either by relatives of the deceased or by medical personnel. When infant ‘unknown’ fatalities were extracted to form a discrete database they showed a curious gender disparity. There were 100 male infant fatalities recorded for every seventy-eight females in the thirty-two counties over the five-year period. On extending the study to 1932, the same ratio was prevalent in the overall dataset of 895 ‘unknown infants’ drawn from the G.R.D.I. (a dataset which excludes the six counties of Northern Ireland for the period from1922). Initial research into the gender imbalance opened out wider questions concerning social mores regarding illegitimacy, and the extent of medical and lay knowledge of how newborn infants might be brought to death.

OBJECTIVE: To build a linguistic model using the properties of fuzzy logic to estimate the risk of death of neonates admitted to a Neonatal Intensive Care Unit.METHODS: Computational model using fuzzy logic. The input variables of the model were birth weight, gestational age, 5th-minute Apgar score and inspired fraction of oxygen in newborn infants admitted to a Neonatal Intensive Care Unit of Taubaté, Southeast Brazil. The output variable was the risk of death, estimated as a percentage. Three membership functions related to birth weight, gestational age and 5th-minute Apgar score were built, as well as two functions related to the inspired fraction of oxygen; the risk presented five membership functions. The model was developed using the Mandani inference by means of Matlab(r) software. The model values were compared with those provided by experts and their performance was estimated by ROC curve.RESULTS: 100 newborns were included, and eight of them died. The model estimated an average possibility of death of 49.7±29.3%, and the possibility of hospital discharge was 24±17.5%. These values are different when compared by Student's t-test (p<0.001). The correlation test revealed r=0.80 and the performance of the model was 81.9%.CONCLUSIONS: This predictive, non-invasive and low cost model showed a good accuracy and can be applied in neonatal care, given the easiness of its use.

Abstract Background: Deaths from inherited metabolic disorders may remain undiagnosed after postmortem examination and may be classified as sudden infant death syndrome. Tandem mass spectrometry (MS/MS) may reveal disorders of fatty acid oxidation in deaths of previously unknown cause. Methods: We obtained filter-paper blood from 7058 infants from United States and Canadian Medical Examiners. Acylcarnitine and amino acid profiles were obtained by MS/MS. Specialized interpretation was used to evaluate profiles for disorders of fatty acid, organic acid, and amino acid metabolism. The analyses of postmortem blood specimens were compared with the analyses of bile specimens, newborn blood specimens, and specimens obtained from older infants at risk for metabolic disorders. Results: Results on 66 specimens suggested diagnoses of metabolic disorders. The most frequently detected disorders were medium-chain and very-long-chain acyl-CoA dehydrogenase deficiencies (23 and 9 cases, respectively), glutaric acidemia type I and II deficiencies (3 and 8 cases, respectively), carnitine palmitoyl transferase type II/translocase deficiencies (6 cases), severe carnitine deficiency (4 cases), isovaleric acidemia/2-methylbutyryl-CoA dehydrogenase deficiencies (4 cases), and long-chain hydroxyacyl-CoA dehydrogenase/trifunctional protein deficiencies (4 cases). Conclusions: Postmortem metabolic screening can explain deaths in infants and children and provide estimates of the number of infant deaths attributable to inborn errors of metabolism. MS/MS is cost-effective for analysis of postmortem specimens and should be considered for routine use by Medical Examiners and pathologists in unexpected/unknown infant and child death.

This study was designed to discover parents' experience following a stillbirth or early infant death. The conceptualization of the research problem was based on Kleinman's (1978) cultural system model which directed the researcher to elicit directly from clients their explanatory models, or their way of viewing the experience. The specific research questions were (1) How do couples perceive and interpret their experience following stillbirth or early infant death? and (2) How do couples view the social support they have received at the time of their infant's death? Six couples, who were recruited primarily from bereavement support groups, participated in the study. Each couple had experienced a stillbirth or early infant death between four months and four years prior to the study. Data were collected from the subjects with the use of unstructured interviews, allowing the experiences to unfold as they were perceived by the participants. Four main themes that evolved from the data were (1) anticipation of parenthood and the shattering of hopes with the death or knowledge of impending death of the infant; (2) a multidimensional personal grief experience; (3) an interpersonal grief exerience influenced by the social support of health care professionals, of friends and family and of the spouse; and (4) reflection and search for meaning in the experience. The discovery of couples' perceptions of their bereavement experience and their view of the support received will assist in enhancing the ability to provide more effective nursing care to bereaved families. Implications for nursing practice, research and education are delineated.<br>Applied Science, Faculty of<br>Nursing, School of<br>Graduate

Thirteen nurses were interviewed over an eight week period to explore their adaptive responses to neonatal death. A process of adaptation was identified that included several phases through which these nurses proceeded before they finalized the death experience for themselves. These phases included responses to the resuscitation of the infant; the measures taken to console the bereaved parents; feelings associated with difficult moments during the dying process; the behaviors utilized to strengthen themselves before and after the death; reactions to the silence in the unit that occurred afterwards; the values they discovered when reflecting on how the death was handled; and the development of a philosophical meaning from their experiences. Data were collected and analyzed using grounded theory methodology.

Aim. The aim of the present research was to investigate the relationship of personality guilt- and shame-proneness to grief and psychological dysphoria following bereavement due to stillbirth or death in the newborn period. Methods. Participating parents completed self-report questionnaire measures of proneness to situational guilt and shame (Test of Self-Conscious Affect-2), chronic guilt and shame (Personal Feelings Questionnaire-2) and interpersonal guilt (Interpersonal Guilt Questionnaire-67), grief (Perinatal Grief Scale-33) and psychological dysphoria (General Health Questionnaire-28) one month (�early�, N = 158) and 13 months (�late�, N = 149) after a perinatal death. Results. Women compared with men self-reported more intense grief, anxiety and depression one month after the death, but there were no significant sex differences in grief or psychological dysphoria one year later. Hierarchical multiple regression analyses showed that composite shame (situational and chronic) explained a small but statistically significant proportion of the variance in early total grief (adjusted R 2 = .09) and anxiety (adjusted R 2 = .07) in women, and early total grief (adjusted R 2 = .19), anxiety (adjusted R 2 = .13) and depression (adjusted R 2 = .10) in men. Composite guilt (situational, chronic and interpersonal) controlled for shame did not make a significant further contribution to the variance in early total grief, anxiety or depression in either sex. Composite shame explained not only significant but meaningful proportions of the variance in late grief (adjusted R2=.27), anxiety (adjusted R2=.21) and depression (adjusted R2=.27) in women, and late grief (adjusted R2= .56),anxiety (adjusted R 2= .30) and depression (adjusted R2= .51) in men. Composite guilt controlled for shame made significant further contributions to the variancein late grief (∆R 2 = .21), anxiety (∆R 2 = .16) and depression (∆R 2 = .25) in women, and late grief (∆R 2 = .11) in men. Shame and guilt together explained a substantial proportion of the variance in late grief (adjusted R2= .45), anxiety (adjusted R2= .33) and depression (adjusted R2= .49) in women, and late grief (adjusted R2= .64), anxiety (adjusted R2= .35) and depression (adjusted R2= .56) in men. Situational shame, chronic guilt and survivor guilt made positive unique contributions to the variance in late grief in women. Chronic shame and survivor guilt made unique contributions to the variance in late grief in men. Situational guilt made a significant unique negatively valenced contribution to the variance in late grief in women. Early composite shame, but not guilt, predicted late grief, anxiety and depression in men. Early composite shame and/or guilt did not predict late grief, anxiety or depression in women. Conclusion. Personality proneness to shame was more relevant to late grief, anxiety and depression in men than in women, but survivor guilt was equally important to late grief in both sexes. Chronic guilt and functional situational guilt were pertinent to late grief, anxiety and depression in women, but not in men. Personality shame- and guilt-proneness have important relationships with parental grief after perinatal death that have not hitherto been recognised.

The issue of child mortality is currently under international spotlight, as the rates of neonatal and under five mortality are sobering. „About 29,000 children under the age of five [approximately] 21 each minute die every day, mainly from preventable causes‟. Although there has been a decline in global child mortality rates since 1990, sub-Saharan Africa still has the highest rates, where one child in eight dies before age five. As contained in the Millennium Development Goals (MDGs) 2010 report, in 2008, sub-Saharan Africa bore half of the 8.8 million deaths in children under five.<br>Thesis (LLM (Human Rights and Democratisation in Africa))--University of Pretoria, 2012.<br>http://www.chr.up.ac.za/<br>nf2012<br>Centre for Human Rights<br>LLM

Thesis (MScMedSc)--Stellenbosch University, 2014.<br>ENGLISH ABSTRACT: Background: Sudden infant death syndrome (SIDS) is considered the second most frequent cause of infant mortality worldwide. Research specifically pertaining to SIDS is limited in the South African setting. Identifiable causes for sudden infant death remain challenging despite full medico-legal investigations inclusive of autopsy, scene visit and ancillary studies. Viral infections could contribute to some sudden unexpected death in infancy (SUDI) cases, especially since a multitude of respiratory viruses have been detected from autopsy specimens. The specific contribution of viruses in the events preceding death, including the subsequent involvement of the immature immune response in infants, still warrants deciphering. Infancy is characterised by marked vulnerability to infections due to immaturities of their immune systems that may only resolve as infants grow older when these sudden deaths rarely still occur. In South Africa there is a lack of a standard protocol for investigations into the causes of SIDS, including the lack of standard guidelines as to which specimens should be taken, which viruses should be investigated and which laboratory assays should be utilised. Objectives: In this prospective descriptive study we aimed to investigate the prevalence of viruses in SUDI and SIDS cases at Tygerberg Forensic Pathology Service (FPS) Mortuary over a one year period. The primary aim was to explore possible respiratory viral infections in SUDI and SIDS cases and to determine the usefulness of molecular techniques to detect viruses from SUDI cases. To determine the significance of viruses, we assessed signs of infection from lung histology. The secondary objectives included collecting demographic data to investigate possible risk factors for SUDI and to look for possible similarities between viruses confirmed in living hospitalised infants at Tygerberg, during the study period compared to viruses detected from SUDI cases. Methods: Between May 2012 and May 2013 samples were collected from 148 SUDI cases presenting at Tygerberg FPS Mortuary. As part of the mandatory routine investigations into SUDI, shell vial culture (SVC) results were collected from lung and liver tissue specimens and bacterial culture results were collected from left and right lung and heart swabs at autopsy. To investigate the possibility of viruses implicated in some of the infant deaths we used the Seeplex® RV15 Ace detection multiplex polymerase chain reaction (PCR) assay to establish the frequency of 13 ribonucleic acid (RNA) respiratory viruses (influenza A and B, human parainfluenza 1-4, human coronavirus [OC43, 229E/NL63], human rhinovirus A, B and C, respiratory syncytial virus A and B, human enterovirus and human metapneumovirus) from RNA extracted from tracheal and lower left and right lung lobe swabs. Tissue from the lower left and right lung lobes were also assessed for histology signs of infection. Results: During our study we confirmed multiple known demographic risk factors for SIDS, such as the age peak around 1-3 months, the male predominance, bed-sharing, sleeping in the prone position, heavy wrapping in warm blankets, prenatal smoke exposure, and socio-economic factors. With the Seeplex® RV15 Ace detection assay between one and three viruses were detected in 59.5% (88/148) of cases. Of the 88 cases that had viruses detected, 75% (66/88) had one virus and 25% (22/88) had co-detections of two to three viruses. The most common viruses detected were HRV in 77% (68/88) of cases, RSV in 18% (16/88) of cases and HCoV in 14% (12/88) of cases. Many of the viruses we detected from our cases are included in the SVC test that forms part of the medico-legal laboratory investigation for all SUDI cases at Tygerberg FPS Mortuary. SVCs were positive in 9.5% (14/148) of all cases only. We showed that the SVC method is potentially missing most of the 13 respiratory viruses we investigated that could contribute to death in some of the SUDI cases. Conclusion: In some cases that had a Cause of Death Classification - SIDS, the PCR viruses detected cannot be ignored, especially when it is supported by histological evidence of infection. We thus propose that the use of PCR could alter a Cause of Death Classification from SIDS to Infection in some of these cases. Further research is needed to determine the significance of detecting viruses from SUDI cases wherein no significant histological evidence of infection was observed. This questions whether PCR may be too sensitive and is detecting past and latent viral infections that do not play any role in the cause of death. The histological picture also requires further characterisation to determine if it accurately predicts infections or lethal events and can truly support virology findings, especially in young infants whose immune systems are still maturing. Without determining the true prevalence of viruses in SUDI cases and the viral-specific immune response, the contribution of virus-specific infections to this syndrome will remain largely undetermined.<br>AFRIKAANSE OPSOMMING: Agtergrond: Wiegiedood (“SIDS/SUDI”) word beskou as die tweede mees algemene oorsaak van sterftes in kinders jonger as een jaar wêreldwyd. Toegewyde SIDS-spesifieke navorsing in die Suid-Afrikaanse samelewing is beperk. Dit bly steeds „n uitdaging om oorsake te probeer identifiseer vir hierdie onverwagte sterftes in kinders (SUDI) ten spyte van volledige medies-geregtelike ondersoeke, insluitende die lykskouing, ondersoek van die doodstoneel en aanvullende ondersoeke. Virusinfeksies kan aansienlik bydra tot sommige onverwagte sterftes in kinders, aangesien verskeie respiratoriese virusse alreeds aangetoon is in monsters verkry tydens outopsies. Die spesifieke rol wat virusse speel in die prosesse wat die dood voorafgaan, asook die bydraende rol van „n onder-ontwikkelde immuunrespons in babas, regverdig verdere ondersoek. Die eerste jaar van lewe word gekenmerk deur verhoogde vatbaarheid vir infeksies weens die ontwikkelende immuunstelsels soos wat babas ouer word, en die voorkoms van SUDI neem stelselmatig af met „n toename in ouderdom. In Suid-Afrika bestaan daar tans geen standaard protokol vir die ondersoek van wiegiedood nie en daar is ook nie standaard riglyne oor die tipe monsters wat geneem moet word, watter virusse ondersoek moet word en watter laboratorium toetse uitgevoer moet word nie. Doelstellings: In hierdie prospektiewe beskrywende studie is gepoog om die virusse wat in gevalle van wiegiedood of SUDI voorkom te ondersoek. Die studie is uitgevoer by die Tygerberg Geregtelike Patologie Dienste lykshuis oor 'n tydperk van een jaar. Molekulêre tegnieke om virusse aan te toon in hierdie gevalle is gebruik om spesifieke virusinfeksies te ondersoek. Die resultate is met histologiese tekens van infeksie in longweefsel gekorreleer. Demografiese data is verder versamel om moontlike risikofaktore vir wiegiedood te ondersoek. Dit is verder vergelyk met virusse wat met dieselfde diagnostiese tegnieke in babas geïdentifiseer is wat tydens die studieperiode in Tygerberg Hospitaal opgeneem was met lugweginfeksies. Metodes: Monsters van 148 SUDI gevalle wat by die Tygerberg lykshuis opgeneem is, is versamel tussen Mei 2012 en Mei 2013. As deel van die roetine ondersoeke in SUDI gevalle, was selkultuur resultate verkry van long en lewer weefsel, asook bakteriële kulture van deppers wat van beide longe en hart geneem was tydens die lykskouings. „n Seeplex® RV15 Ace polimerase kettingreaksie (PKR) toets is gebruik om die teenwoordigheid van virusse te ondersoek wat moontlik by die babasterftes betrokke kon wees. Trageale- en longdeppers wat tydens die lykskouings versamel was, was getoets vir 13 ribonukleïensure (RNS) respiratoriese virusse (influenza A and B, human parainfluenza 1-4, human coronavirus [OC43, 229E/NL63], human rhinovirus A, B and C, respiratory syncytial virus A and B, human enterovirus and human metapneumovirus). Resultate: Ons studie het verskeie bekende demografiese risikofaktore vir SUDI bevestig, byvoorbeeld „n ouderdomspiek tussen een en drie maande ouderdom, manlike predominansie, deel van „n bed met ander persone, slaap posisie op die maag, styf toedraai in warm komberse, blootstelling aan sigaretrook voor geboorte en sosio-ekonomiese faktore. Die Seeplex® RV15 Ace toets het tussen een en drie virusse geïdentifiseer in 59.5% (88/148) van die gevalle. Uit die 88 gevalle waarin virusse opgespoor was, was selgs een virus in 75% (66/88) van gevalle gevind en twee en drie virusse in 25% (22/88). Die mees algemene virusse was HRV in 77% (68/88) van gevalle, RSV in 18% (16/88) van gevalle en HCoV in 14% (12/88) van gevalle. Baie van die virusse wat tydens hierdie studie ondersoek was, was ingesluit in die roetine selkultuur toets wat deel vorm van die standaard medies-geregtelike laboratoriumondersoeke in alle SUDI gevalle by die Tygerberg lykshuis, alhoewel die selkulture positief was in slegs 9.5% (14/148) van gevalle. Ons het gevind dat baie respiratoriese virusse potensieel gemisdiagnoseer word wat „n rol kon speel in of bydra tot die dood van sommige SUDI gevalle. Gevolgtrekking: In sommige gevalle waarin SIDS geklassifiseer is as die oorsaak van dood, kan die virusse wat met PKR toetse opgespoor is nie geïgnoreer word nie, veral waar die bevinding ondersteun word deur histologiese bewyse van infeksie. Ons stel dus voor dat die gebruik van PKR toetse die oorsaak van dood klassifikasie kan verander van SIDS na Infeksie in sommige van hierdie gevalle. Verdere navorsing is nodig om die waarde van gelyktydige opsporing van virusse in SUDI gevalle te bepaal wanneer daar geen noemenswaardige histologiese bewyse van infeksie gevind word nie. Dit bevraagteken of die PKR toets dalk te sensitief is en gevolglik vorige en latente virusinfeksies identifiseer wat nie noodwendig 'n rol in die oorsaak van dood speel nie. Die diagnostiese en kliniese waarde van die histologiese beeld in terme van die rol van virusinfeksies as bydraende oorsaak van dood moet verder ondersoek word, veral in jong kinders wie se immuunstelsels nog nie volledig ontwikkel is nie. Indien die werklike voorkoms van virusse in SUDI gevalle en die virus-spesifieke immuunrespons nie bepaal word nie, sal die rol van virus-spesifieke infeksies in hierdie sindroom grootliks onbekend bly.<br>Harry Crossley Foundation<br>Poliomyelitis Research Foundation (PRF)<br>National Health Laboratory Services Research Trust

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.

Thesis (MPhil)--University of Stellenbosch, 2004.<br>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<br>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.

United Nations has lately stated ambitious health targets for 2030 in the Sustainable Development Goal agenda, following the already achieved progress between 1990 and 2015 when the number of children dying before the age of five was reduced by more than half. However, the mortality reduction in the first month of life after birth has not kept the same pace. Furthermore, a large number of stillbirths have previously not been accounted for. The aim of this thesis was to evaluate the impact of clinical training in neonatal resuscitation, and to identify strategies for an effective implementation at a maternal health facility in Nepal. Focus group discussions were used to explore the perceptions of teamwork among staff working closest to the infant at the facility. A prospective cohort study with nested referents was applied to determine effect on birth outcomes after an intervention with Helping Babies Breathe, a simplified protocol for neonatal resuscitation. Sustainability of the acquired skills after training was addressed by employing a quality improvement cycle. Video recordings of health workers performance were collected to analyse adherence to protocol. Midwives described the need for universal protocols in neonatal resuscitation and management involvement in clinical audit and feedback. There was a reduction of intrapartum stillbirth (aOR 0.46, 95% CI 0.32–0.66) and neonatal mortality within 24 hours of life (aOR 0.51, 95% CI 0.31–0.83) after the intervention. Ventilation of infants increased (OR 2.56, 95% CI 1.67–3.93) and potentially harmful suctioning was reduced (OR 0.13, 95% CI 0.09–0.17). Neonatal death from intrapartum-related complications was reduced and preterm infants survived additional days in the neonatal period after the intervention. Low birth weight was not found to be a predictor of deferred resuscitation in the studied context. This study confirmed the robustness of Helping Babies Breathe as an educational tool for training in neonatal resuscitation. Accompanied with a quality improvement cycle it reduced intrapartum stillbirth and mortality on the day of delivery in a low-income facility setting. Improved postnatal care is needed to maintain the gains in survival through the neonatal period. Increased management involvement in audit and quality of care could improve clinical performance among health workers.

Since antiquity, cot death was explained as accidental suffocation, overlaying, or smothering. Parents were blamed for neglect or drunkenness, and a cage called arcuccio was invented around 1570 to protect the sleeping infant. Up to the 19th century, accidents were registered as natural causes of death. From 1830, accidental suffocation became unacceptable for physicians and legislators, and ‘natural’ explanations for the catastrophe were sought, with parents being consoled rather than blamed. Prone sleeping originated in the 1930s and from 1944 was associated with cot death. However, from the 1960s many authors recommended prone sleeping for infants, and many countries adopted the advice. A worldwide epidemic followed, peaking at 2% in England and Wales and 5% in New Zealand in the 1980s. Although epidemiological evidence was available by 1970, the first intervention was initiated in the Netherlands in 1989. Cot death disappeared almost entirely wherever prone sleeping was avoided. This strongly supports the assumption that prone sleeping has the greatest influence on the disorder, and that the epidemic resulted from wrong advice.

The frequency of breech presentation at term is 3% among singletons. Greek physicians dreaded those births, as they frequently led to the death of mother, infant, or both. In Rome, surviving infants were named Agrippa (born with difficulty), and the goddess Postverta was revered for presiding over breech deliveries. To the antique procedures of embryotomy and hook for the dead infant, the Middle Ages added manoeuvres to turn and extract a living, albeit often traumatized infant. These manoeuvres were associated with asphyxia from cord prolapse or compression, fracture of legs, arms, or clavicles, cerebral haemorrhage, trauma to the cerebellum, tentorium, or pituitary stalk, and with torticollis and arm plexus palsy. The prototype of difficult birth, infants born feet-first were considered dangerous, and were neglected or killed in many cultures. Even after Caesarean section had lost most of its risk, conservative obstetricians still propagated vaginal delivery from breech presentation. Finally, at the beginning of the 21st century, large randomized trials and population-based studies proved that Caesarean delivery was safe for the mother and highly beneficial for the child, making vaginal delivery from breech presentation obsolete.

In Germany, paediatrics evolved at the end of the 19th century in an atmosphere of social Darwinism and nationalism which paved the way towards elimination of handicapped infants. Killing handicapped children was organized in Hitler’s Chancellery from 1939, targeting infants with idiocy and mongolism, micro- or hydrocephaly, malformed limbs, head, or spine, and palsies. A system of reporting and rating such infants was established, leading to their admission to one of 30 ‘Special Children’s Departments’. There, sedatives were applied in a dose depressing respiration which led to a slow death disguised as natural. A hundred physicians were directly involved in killing, and many more including eminent paediatricians in reporting infants. After the war, court trials were initiated, but usually discontinued. Physicians involved in murdering children continued to teach and to conduct research on the victims’ brains. Their textbooks conveyed little compassion for the weak, malformed, and handicapped. There was widespread unwillingness to keep preterm infants alive. When from 1960 artificial ventilation of neonates became possible, opposition against it persisted. Despising the weak was an enduring legacy of Nazism that may have delayed the introduction of modern neonatology in Europe.

Nearly 2% of all pregnancies nowadays are complicated by maternal pregestational or gestational diabetes. Long before diabetic fetopathy was acknowledged, macrosomia was dreaded by obstetricians because of the trauma risk and the need for mutilating operations. Diabetic fetopathy was described and maternal glucosuria quantified by Henrich Bennewitz in 1824. However, most authors ignored his findings and well into the 20th century, series of ‘giant babies’ were published without even mentioning diabetes mellitus. When insulin became available in 1923, maternal but not fetal mortality decreased. In 1952, Priscilla White classified six forms of maternal diabetes during pregnancy and reported an overall intrauterine, intrapartum, and neonatal death rate of 45%. But not all those infants died from macrosomia-associated traumatism and birth asphyxia: the main finding in the deceased infants was pulmonary hyaline membranes, demonstrated by Louis Gluck in 1973 to result from retarded surfactant maturation in diabetic fetuses.

This chapter describes the development of the infant in the third month of life. After being warned by her pediatrician that her son has a flat head from sleeping on his back, the author discusses the common newborn issues of plagiocephaly and torticollis, how these diagnoses became popular, sudden infant death syndrome (SIDS), and how back sleeping might slow the development of motor milestones. She goes on to describe the development of infants’ motor skills like sitting, crawling, and walking, and the factors (including back sleeping) that might affect the timing of motor milestones. She concludes with a discussion of potential intervention strategies for babies with plagiocephaly.

In many religions, body secretions have been regarded as impure or dangerous. Meconium, the pitch-like substance filling the gut at birth, was considered the embodiment of impurity and actively driven out from the newborn’s body. The custom was advantageous by breaking the taboo on colostrum consumption. Passing the meconium before birth was considered a bad omen. The claim that it indicated fetal death led to intense debates between the Parisian surgeons Viardel and Mauriceau. In 1798, Scheel described meconium aspiration into the airways, a severe disease still causing 1000 deaths annually in the US in 2008. Meconium ileus resulted from a hardened substance within the gut, linked to cystic fibrosis of the pancreas by Landsteiner in 1905. Meconium peritonitis, described by Morgagni in 1751, resulted when the dilated gut perforated during fetal life. A series of meconium occlusion and peritonitis were described in 1877 among infants admitted to the St. Petersburg Foundling Hospital. For centuries, ‘expelling’ the meconium was a postnatal routine with similarities to exorcism, freeing the child from evil.

This chapter covers infections in neonates and young children. In this chapter the term ‘young children’ indicates children under two years of age. For information on congenital infections interested readers are referred to Chapter 37. Early neonatal infection is variably defined as infection presenting up to a week after birth, but most infections present in the first seventy-two hours. Microbial invasion of the chorio-amniotic membranes or uterine cavity occur in a significant proportion of pregnancies before rupture of membranes (&gt; 50% with preterm birth before thirty weeks gestation, 10% with term delivery), and in the majority of those with prolonged rupture of membranes (&gt; 24 hours). It is likely that the majority of cases of early sepsis arise through ascending infection of the uterus (through the cervical canal). Ascending infection may be important in the pathogenesis of preterm birth and is more common in infants born preterm. Group B Streptococci (GBS) (Streptococcus agalactiae) and Escherichia coli are the most common agents of early neonatal infection. Infection with Listeria monocytogenes probably arises following ingestion of contaminated food by the mother, blood stream infection, and transplacental spread. Early infection with GBS usually presents with respiratory distress and can be difficult to differentiate from respiratory distress associated with other causes, particularly prematurity. The incidence of GBS blood stream infection in England and Wales has been 0.3–0.45/ 1000 live births over the last five years. Maternal genital herpes simplex infection can spread to the newborn infant and cause a wide range of serious clinical presentations, with skin, systemic, and central nervous system involvement. Maternal infection with Neisseria gonorrhoea or Chlamydia trachomatis can also infect the infant. Either can cause conjunctivitis which can sometimes be of sufficient severity to cause substantial damage to the eyes. Gonococcal conjunctivitis usually presents in the first few days of life. Infection with Chlamydia trachomatis (conjunctivitis or pneumonitis) tends to present later. Traditionally, penicillin and an aminoglycoside have been used to treat infants with suspected early sepsis (to cover GBS and Escherichia coli). Newborn infants are often empirically treated because it can be difficult to differentiate early bacterial sepsis from respiratory distress associated with prematurity, and death may ensue rapidly if the infection is not treated.

This chapter describes the development of the fetus in the fifth month of pregnancy. After discovering that her fetus was inconveniently sleeping through an important ultrasound, the author discusses the science of infant sleep, why fetuses and newborns sleep so much, and the potential importance of rapid eye movement (REM) sleep for a fetus’s developing visual system. She then discusses at length various sleep-related issues relevant to infancy, including the controversial issues of co-sleeping (whether parents should do it and why), and an in-depth description of the research on sleep training and its potential short term and long terms effects on infants.

Approximately 904,000 newborns die of breathing complications, or birth asphyxia, each year[1]. It is estimated that 30% of these deaths could be prevented[2]; however, healthcare workers in developing nations often lack the training, skills, or equipment necessary to properly resuscitate these infants. For this reason, child mortality is disproportionally clustered in low-resource locations in which the current standard of care is ineffective. The bag-valve mask resuscitator (or BVM) is the recommended treatment for a newborn who is not breathing properly.

In Kenya, although 45 percent of maternal deaths occur within the first 24 hours after childbirth and 65 percent of maternal deaths occur during the first week postpartum, health-care providers continue to advise on a first check-up six weeks after childbirth. The early postpartum period is also critical to newborn survival, with 50–70 percent of life-threatening newborn illnesses occurring in the first week. Yet most strategies to reduce maternal and perinatal morbidity and mortality have focused on pregnancy and birth. In addition to the heavy workload of providers who do not assess the mother post-delivery when she may bring her infant for immunization, lack of knowledge, poverty, cultural beliefs and practices perpetuate the problem. The only register that exists for mothers post-delivery is for family planning, thus perpetuating the lack of emphasis on the early postpartum period with no standardized register to record care given. To address this gap in service delivery, the Population Council defined the minimal services a mother and baby should receive from a skilled attendant after birth. As stated in this brief, the development of a standardized postpartum register is one step toward advocating for providing early postpartum care among health-service providers.
