Asia Pregnancy Outcomes Study
Neonatal DeathStillbirthPreterm birth is a major cause of child mortality and morbidity, most of which occurs in south-east Asia and sub-Saharan Africa. To date few neonatal cause of death studies, especially in low- and middle-income countries have determined the specific causes of preterm death, instead attributing all neonatal deaths of infants born at less than 37 weeks to prematurity. Infections are responsible for a large proportion of these deaths but because of complexity and costs associated with testing, little is known about the prevalence of infection-related deaths in preterm infants or the specific pathogens associated with mortality. The primary objective of this study is to determine the cause of deaths among preterm births and stillbirths. Secondary outcomes include determining the specific pathogens responsible for infection-related deaths, potential preventability of these deaths and interventions which may reduce mortality. One site in India and one in Pakistan will include a total sample size of 700 (350 stillbirths and 350 preterm neonatal deaths) for 1,400 cases to be included in the cause of death analyses. All women who deliver a preterm birth or a stillbirth at the study hospitals will be eligible for inclusion. Among those who consent, an obstetric history, clinical obstetric and (if applicable) neonatal care will be collected as well as research investigations including ultrasound, x-ray, microbiology and minimally invasive tissue sampling and autopsy will be collected. This study will align with other efforts to determine cause of death among infants and children and ultimately the results will inform future interventions to reduce neonatal mortality and stillbirth. The researchers emphasize that this study, with its focus on preterm neonatal mortality and stillbirth, will provide information not available elsewhere.
Ultrasound Monitoring of Fetuses With Vascular Intra-uterine Growth Restriction (IUGR) Using the...
IUGRFetuses with IUGR, there is a correlation between Doppler indices of cardiovascular function and perinatal mortality. An index of systolic flow velocities at the aortic isthmus (ISI) has previously been described in a population of normal fetuses. Fetuses with IUGR, the velocities recorded in the aortic isthmus could be affected and the normal development of the ISI should be changed, because of the increase in placental resistance on one hand, and the gradual deterioration ventricular functions on the other one. Investigators hypothesize that the ISI index in the context of placental insufficiency could provide additional arguments on the extraction timing, the prognosis and the fetal extraction mode to severe hypoxia. The primary outcome of the study is to evaluate in an exploratory manner the feasibility and the potential interest of longitudinal monitoring of fetuses with IUGR by Doppler systolic isthmus and the calculation of the ISI index.
Machine Learning From Fetal Flow Waveforms to Predict Adverse Perinatal Outcomes
Perinatal MortalityNeonatal MorbiditiesThe aim of this study is to get a proof of concept for using a computational model of fetal haemodynamics, combined with machine learning based on Doppler patterns of the fetal cardiovascular, cerebral and placental flows, to identify those at increased risk of adverse perinatal outcomes such as stillbirth, perinatal mortality and other neonatal morbidities. We will also compare the sensitivity and specificity of UmbiFlow device with the machine learning model in predicting adverse perinatal outcomes
Predictive Score for Neonatal Mortality for Women With Premature Rupture of Membranes Between 22...
Perinatal MortalityPremature Rupture of Fetal MembranesPretern premature rupture of the membranes (PPROM) remains the leading cause of preterm deliveries and neonatal mortality and morbidity. PPROM is defined as rupture of the fetal membranes prior to 37 weeks' gestation. PPROM complicates 2-4% of all pregnancies and accounts for approximately 30 % of preterm births. The etiology of PPROM remains elusive. PPROM is one of the main causes of prematurity and its complications, such as newborn respiratory distress syndrome, neonatal sepsis, necrotizing enterocolitis, intraventricular hemorrhage, perventricular leucomalacia, varying degrees of lung hypoplasia and bronchopulmonary dysplasia. All these factors contribute greatly to an increase in neonatal morbidity and mortality Management of PPROM followed actual guidelines. Conservative management to prolong a pregnancy is a classical approach to treat PPROM before 34 weeks' gestation in association with antibiotic therapy and corticosteroids. Maternal and neonatal data were collected from maternal and newborns medical records.
Evaluating the NeoTree in Malawi and Zimbabwe
PrematurityNeonatal Encephalopathy8 moreNeonatal mortality remains unacceptably high. Globally, the majority of mothers now deliver in health facilities in low resource settings where quality of newborn care is poor. Health systems strengthening through digitial quality improvement systems, such as the Neotree, are a potential solution. The overarching aim of this study is to complete the co-development of NeoTree-gamma with key functionalities configured, operationalised, tested and ready for large scale roll out across low resource settings. Specific study objectives are as follows: To further develop and test the NeoTree at tertiary facilities in Malawi and Zimbabwe To investigate HCPs and parent/carer view of the NeoTree, including how acceptable and usable HCWs find the app, and potential barriers and enablers to implementing/using it in practice. To collect outcome data for newborns from representative sites where NeoTree is not implemented. To test the clinical validity of key NeoTree diagnostic algorithms, e.g. neonatal sepsis and hypoxic ischaemic encephalopathy (HIE) against gold standard or best available standard diagnoses. To add dashboards and data linkage to the functionality of the NeoTree To develop and test proof of concept for communicating daily electronic medical records (EMR) using NeoTree To initiate a multi-country network of newborn health care workers, policy makers and academics. To estimate cost of implementing NeoTree at all sites and potential costs at scale
