Estimating the birth prevalence and pregnancy outcomes of congenital malformations worldwide.

Congenital anomaly registries have two main surveillance aims: firstly to define baseline epidemiology of important congenital anomalies to facilitate programme, policy and resource planning, and secondly to identify clusters of cases and any other epidemiological changes that could give early warning of environmental or infectious hazards. However, setting up a sustainable registry and surveillance system is resource-intensive requiring national infrastructure for recording all cases and diagnostic facilities to identify those malformations that that are not externally visible. Consequently, not all countries have yet established robust surveillance systems. For these countries, methods are needed to generate estimates of prevalence of these disorders which can act as a starting point for assessing disease burden and service implications. Here, we describe how registry data from high-income settings can be used for generating reference rates that can be used as provisional estimates for countries with little or no observational data on non-syndromic congenital malformations.

Making stillbirths visible: a systematic review of globally reported causes of stillbirth.

BACKGROUND: Stillbirth is a global health problem. The World Health Organization (WHO) application of the International Classification of Diseases for perinatal mortality (ICD-PM) aims to improve data on stillbirth to enable prevention. OBJECTIVES: To identify globally reported causes of stillbirth, classification systems, and alignment with the ICD-PM. SEARCH STRATEGY: We searched CINAHL, EMBASE, Medline, Global Health, and Pubmed from 2009 to 2016. SELECTION CRITERIA: Reports of stillbirth causes in unselective cohorts. DATA COLLECTION AND ANALYSIS: Pooled estimates of causes were derived for country representative reports. Systems and causes were assessed for alignment with the ICD-PM. Data are presented by income setting (low, middle, and high income countries; LIC, MIC, HIC). MAIN RESULTS: Eighty-five reports from 50 countries (489 089 stillbirths) were included. The most frequent categories were Unexplained, Antepartum haemorrhage, and Other (all settings); Infection and Hypoxic peripartum (LIC), and Placental (MIC, HIC). Overall report quality was low. Only one classification system fully aligned with ICD-PM. All stillbirth causes mapped to ICD-PM. In a subset from HIC, mapping obscured major causes. CONCLUSIONS: There is a paucity of quality information on causes of stillbirth globally. Improving investigation of stillbirths and standardisation of audit and classification is urgently needed and should be achievable in all well-resourced settings. Implementation of the WHO Perinatal Mortality Audit and Review guide is needed, particularly across high burden settings. FUNDING: HR, SH, SHL, and AW were supported by an NHMRC-CRE grant (APP1116640). VF was funded by an NHMRC-CDF (APP1123611). TWEETABLE ABSTRACT: Urgent need to improve data on causes of stillbirths across all settings to meet global targets. PLAIN LANGUAGE SUMMARY: Background and methods Nearly three million babies are stillborn every year. These deaths have deep and long-lasting effects on parents, healthcare providers, and the society. One of the major challenges to preventing stillbirths is the lack of information about why they happen. In this study, we collected reports on the causes of stillbirth from high-, middle-, and low-income countries to: (1) Understand the causes of stillbirth, and (2) Understand how to improve reporting of stillbirths. Findings We found 85 reports from 50 different countries. The information available from the reports was inconsistent and often of poor quality, so it was hard to get a clear picture about what are the causes of stillbirth across the world. Many different definitions of stillbirth were used. There was also wide variation in what investigations of the mother and baby were undertaken to identify the cause of stillbirth. Stillbirths in all income settings (low-, middle-, and high-income countries) were most frequently reported as Unexplained, Other, and Haemorrhage (bleeding). Unexplained and Other are not helpful in understanding why a baby was stillborn. In low-income countries, stillbirths were often attributed to Infection and Complications during labour and birth. In middle- and high-income countries, stillbirths were often reported as Placental complications. Limitations We may have missed some reports as searches were carried out in English only. The available reports were of poor quality. Implications Many countries, particularly those where the majority of stillbirths occur, do not report any information about these deaths. Where there are reports, the quality is often poor. It is important to improve the investigation and reporting of stillbirth using a standardised system so that policy makers and healthcare workers can develop effective stillbirth prevention programs. All stillbirths should be investigated and reported in line with the World Health Organization standards.

The effect of coverings, including plastic bags and wraps, on mortality and morbidity in preterm and full-term neonates.

Neonatal hypothermia is an important risk factor for mortality and morbidity, and is common even in temperate climates. We conducted a systematic review to determine whether plastic coverings, used immediately following delivery, were effective in reducing the incidence of mortality, hypothermia and morbidity. A total of 26 studies (2271 preterm and 1003 term neonates) were included. Meta-analyses were conducted as appropriate. Plastic wraps were associated with a reduction in hypothermia in preterm (⩽29 weeks; risk ratio (RR)=0.57; 95% confidence interval (CI) 0.46 to 0.71) and term neonates (RR=0.76; 95% CI 0.60 to 0.96). No significant reduction in neonatal mortality or morbidity was found; however, the studies were underpowered for these outcomes. For neonates, especially preterm, plastic wraps combined with other environmental heat sources are effective in reducing hypothermia during stabilization and transfer within hospital. Further research is needed to quantify the effects on mortality or morbidity, and investigate the use of plastic coverings outside hospital settings or without additional heat sources.

Lack of evidence for the efficacy of enhanced surveillance compared to other specific interventions to control neonatal healthcare-associated infection outbreaks.

BACKGROUND: Despite current prevention efforts, outbreaks of healthcare-associated infections in neonatal units remain high globally, with a considerable burden of mortality and morbidity. METHODS: We searched Medline, Cochrane Library and Outbreak database to identify studies of neonatal healthcare-associated outbreaks between 2005 and 2015 that described interventions to control outbreaks. All studies were evaluated using the ORION guidance. RESULTS: Thirty studies were identified including 17 102 infants of whom 664 (3.9%) became infected. No single intervention was identified that reduced duration or mortality. Studies that introduced multiple interventions had significantly reduced case fatality ratio and outbreak duration compared to those that used basic surveillance only. Low and low-middle income countries reported the fewest interventions to control outbreaks and these studies were also associated with higher mortality than that found in middle and high income countries. CONCLUSIONS: Systematic reporting and formal evaluation of interventions used to reduce healthcare-associated neonatal infection outbreaks is key to identifying containment strategies worldwide.

Use of wind-up fetal Doppler versus Pinard for fetal heart rate intermittent monitoring in labour: a randomised clinical trial.

OBJECTIVES: In resource-poor settings, the standard of care to inform labour management is the partograph plus Pinard stethoscope for intermittent fetal heart rate (FHR) monitoring. We compared FHR monitoring in labour using a novel, robust wind-up handheld Doppler with the Pinard as a primary screening tool for abnormal FHR on perinatal outcomes. DESIGN: Prospective equally randomised clinical trial. SETTING: The labour and delivery unit of a teaching hospital in Kampala, Uganda. PARTICIPANTS: Of the 2042 eligible antenatal women, 1971 women in active term labour, following uncomplicated pregnancies, were randomised to either the standard of care or not. INTERVENTION: Intermittent FHR monitoring using Doppler. PRIMARY OUTCOME MEASURES: Incidence of FHR abnormality detection, intrapartum stillbirth and neonatal mortality prior to discharge. RESULTS: Age, parity, gestational age, mode of delivery and newborn weight were similar between study groups. In the Doppler group, there was a significantly higher rate of FHR abnormalities detected (incidence rate ratio (IRR)=1.61, 95% CI 1.13 to 2.30). However, in this group, there were also higher though not statistically significant rates of intrapartum stillbirths (IRR=3.94, 0.44 to 35.24) and neonatal deaths (IRR=1.38, 0.44 to 4.34). CONCLUSIONS: Routine monitoring with a handheld Doppler increased the identification of FHR abnormalities in labour; however, our trial did not find evidence that this leads to a decrease in the incidence of intrapartum stillbirth or neonatal death.

Where do pulse oximeter probes break?

Pulse oximetry, a non-invasive method for accurate assessment of blood oxygen saturation (SPO2), is an important monitoring tool in health care facilities. However, it is often not available in many low-resource settings, due to expense, overly sophisticated design, a lack of organised procurement systems and inadequate medical device management and maintenance structures. Furthermore medical devices are often fragile and not designed to withstand the conditions of low-resource settings. In order to design a probe, better suited to the needs of health care facilities in low-resource settings this study aimed to document the site and nature of pulse oximeter probe breakages in a range of different probe designs in a low to middle income country. A retrospective review of job cards relating to the assessment and repair of damaged or faulty pulse oximeter probes was conducted at a medical device repair company based in Cape Town, South Africa, specializing in pulse oximeter probe repairs. 1,840 job cards relating to the assessment and repair of pulse oximeter probes were reviewed. 60.2 % of probes sent for assessment were finger-clip probes. For all probes, excluding the neonatal wrap probes, the most common point of failure was the probe wiring (>50 %). The neonatal wrap most commonly failed at the strap (51.5 %). The total cost for quoting on the broken pulse oximeter probes and for the subsequent repair of devices, excluding replacement components, amounted to an estimated ZAR 738,810 (USD $98,508). Improving the probe wiring would increase the life span of pulse oximeter probes. Increasing the life span of probes will make pulse oximetry more affordable and accessible. This is of high priority in low-resource settings where frequent repair or replacement of probes is unaffordable or impossible.

Newborn survival in low resource settings--are we delivering?

The annual toll of losses resulting from poor pregnancy outcomes include half a million maternal deaths, more than three million stillbirths, of whom at least one million die during labour and 3.8 million neonatal deaths--up to half on the first day of life. Neonatal deaths account for an increasing proportion of child deaths (now 41%) and must be reduced to achieve Millennium Development Goal (MDG) 4 for child survival. Newborn survival is also related to MDG 5 for maternal health as the interventions are closely linked. This article reviews current progress for newborn health globally, with a focus on the countries where most deaths occur. Three major causes of neonatal deaths (infections, complications of preterm birth, intrapartum-related neonatal deaths) account for almost 90% of all neonatal deaths. The highest impact interventions to address these causes of neonatal death are summarised with estimates of potential for lives saved. Two priority opportunities to address newborn deaths through existing maternal health programmes are highlighted. First, antenatal steroids are high impact, feasible and yet under-used in low resource settings. Second, with increasing investment to scale up skilled attendance and emergency obstetric care, it is important to include skills and equipment for simple immediate newborn care and neonatal resuscitation. A major gap is care during the early postnatal period for mothers and babies. There are promising models that have been tested mainly in research studies in Asia that are now being adapted and evaluated at scale including through a network of African implementation research trials.

Unseen blindness, unheard deafness, and unrecorded death and disability: congenital rubella in Kumasi, Ghana.

OBJECTIVES: Although rubella serosusceptibility among women of reproductive age in West Africa ranges from 10% to 30%, congenital rubella syndrome has not been reported. In Ghana, rubella immunization and serologic testing are unavailable. Our objectives were to identify congenital rubella syndrome cases, ascertain rubella antibody seroprevalence during pregnancy, and recommend strategies for congenital rubella syndrome surveillance. METHODS: Congenital rubella syndrome cases were identified through prospective surveillance and retrospective surveys of hospital records. A rubella serosurvey of pregnant urban and rural women was performed. RESULTS: Eighteen infants born within a 5-month period met the congenital rubella syndrome case definitions, coinciding with a 9-fold increase in presentation of infantile congenital cataract. The congenital rubella syndrome rate for this otherwise unrecorded rubella epidemic was conservatively estimated to be 0.8 per 1000 live births. A postepidemic rubella immunity rate of 92.6% was documented among 405 pregnant women; susceptibility was significantly associated with younger age (P = .000) and ethnicity (northern tribes, P = .024). CONCLUSIONS: Congenital rubella syndrome occurs in Ghana but is not reported. Information about congenital rubella syndrome and rubella in sub-Saharan Africa is needed to evaluate inclusion of rubella vaccine in proposed measles control campaigns.

Food affordability in air stage communities.

In 1991 and 1992, changes were made to the rate structure and eligibility requirements of the Northern Air Stage Program. To determine the effect of these changes on the affordability of a nutritious diet, food price surveys were conducted in 20 isolated communities, staging points, and selected southern cities and used to cost a 46-item Northern Nutritious Food Basket (NFB), which meets the nutrient requirements of a reference family of four. Food affordability was calculated as the percentage of "after-shelter" social assistance income required to purchase the NFB. In the Northwest Territories (NWT), from 100% to 123% of income was required in Air Stage communities in 1990-1991 and from 86% to 125% in 1993. In the provinces, from 65% to 83% of income was needed in 1990-1991 and from 56% to 98% in 1993. In Kangiqsujuaq and Nain, the amount of "after-shelter" income needed increased by as much as 6% and 15%, respectively. Changes to the Northern Air Stage Program reduced the cost of perishable foods and improved the affordability of a nutritious diet in the NWT. Affordability is also affected by social assistance income. In most isolated communities, families would still find it difficult to afford a nutritious diet.

Food consumption patterns of Inuit women.

To evaluate nutrient intake and food consumption patterns of Inuit women of child-bearing age, a 24-hour diet recall and general health and food frequency questionnaire was administered to 688 Inuit women aged 15-44 in six isolated communities. Data were analyzed using the 1991 Canadian Nutrient File. Mean intakes of essential nutrients were expressed as percentages of Health Canada's 1990 Recommended Nutrient Intakes (RNI). Chi-square tests were used to determine relationships between categorical variables. Folacin intake ranged from 49% to 95% of the RNI in most communities (median = 76%) and was only 37% of the RNI for pregnant and 54% for lactating women. Mean calcium intake for pregnant and lactating women averaged 55% and 47% of the RNI, respectively. Average vitamin A intakes ranged from 26% to 87% of the RNI (median = 65%), with intake for pregnant Inuit women and lactating women 79% and 54% of the RNI, respectively. Country food was the major source of protein and iron, and store foods the major source of calories, calcium, folacin, and vitamin A. Low intakes of folacin, calcium, and vitamin A, especially among pregnant and lactating women, place Inuit women of childbearing age at risk. Women on social assistance are nutritionally vulnerable.

Nutrition education for Native treatment centres.

Based on a needs assessment of native treatment centres and a pilot training project, a 10-day nutrition workshop was offered to 49 counsellors and cooks from 30 native treatment centres from six provinces. Objectives were to: 1) improve the understanding of the effect of alcohol on health and nutrition; 2) to improve the understanding of the role of nutrition in rehabilitation; 3) to clarify their respective roles and 4) to improve skills in menu planning for recovery and special diets, food safety procedures and cooking techniques appropriate for recovery. Assessment, counselling and treatment were considered in relation to native cultural values, meeting basic human needs and counselling theory. Participants rated the following at four or five (on a scale of one to five): meeting their expectations (98%); improving their understanding of the role of nutrition in total well being and recovery (98%); the effect of alcohol on health and nutrition (98%); the recovery diet (96%), special diets and planning and adapting menus (94%) and food safety (96%); developing skills in nutritional assessment (92%) and counselling (89%). Ninety-two percent were interested in further training and 94% of participants would recommend this training to others in the addiction field.
