AI Article Synopsis

  • The study aims to find factors affecting perinatal and infant mortality rates across different primary care trusts (PCTs) in England, identifying those with worse than expected outcomes.
  • The research used complex statistical models that accounted for influences like deprivation, ethnicity, and maternal age to analyze mortality rates, revealing that these factors significantly predicted outcomes.
  • Results showed that increased spending on maternal services didn't correlate with lower mortality rates, suggesting that addressing social determinants like socioeconomic status may be more critical.

Article Abstract

Objective: To identify predictors of perinatal and infant mortality variations between primary care trusts (PCTs) and identify outlier trusts where outcomes were worse than expected.

Design: Prognostic multivariable mixed models attempting to explain observed variability between PCTs in perinatal and infant mortality. We used these predictive models to identify PCTs with higher than expected rates of either outcome.

Setting: All primary care trusts in England. Population For each PCT, data on the number of infant and perinatal deaths, ethnicity, deprivation, maternal age, PCT spending on maternal services, and "Spearhead" status.

Main Outcome Measures: Rates of perinatal and infant mortality across PCTs.

Results: The final models for infant mortality and perinatal mortality included measures of deprivation, ethnicity, and maternal age. The final model for infant mortality explained 70% of the observed heterogeneity in outcome between PCTs. The final model for perinatal mortality explained 80.5% of the between-PCT heterogeneity. PCT spending on maternal services did not explain differences in observed events. Two PCTs had higher than expected rates of perinatal mortality.

Conclusions: Social deprivation, ethnicity, and maternal age are important predictors of infant and perinatal mortality. Spearhead PCTs are performing in line with expectations given their levels of deprivation, ethnicity, and maternal age. Higher spending on maternity services using the current configuration of services may not reduce rates of infant and perinatal mortality.

Perinatal mental health disorders are a significant contributor to morbidity and mortality in childbearing women. The World Health Organization recommends all women be screened for mental health disorders postnatally and have diagnostic and management services available. There are, however, currently no global indicators in use which measure the status and progress of perinatal mental health.

Sequestration of parasites in the placental vasculature causes increased morbidity and mortality in pregnant compared to non-pregnant patients in malaria- endemic regions. In this study, outbred pregnant CD1 mice with semi allogeneic fetuses were infected with transgenic or mock-inoculated by mosquito bite at either embryonic day (E) 6 (first trimester-equivalent) or 10 (second trimester- equivalent) and compared with non-pregnant females. -infected mosquitoes had greater biting avidity for E10 dams than uninfected mosquitoes, which was not apparent for E6 dams nor non-pregnant females.

Introduction The association of acute pancreatitis with adverse obstetric outcomes remains subject to great controversy. Outcomes are affected by the standard of care available, and hence, will be better in developed countries than in underdeveloped countries like Pakistan. Therefore, this study aimed to understand the clinical characteristics and treatment of acute pancreatitis in pregnancy (APIP) and its associated maternal and neonatal outcomes in a tertiary care hospital in Pakistan.

Following a perinatal death, parents can experience mental health difficulties and social stigma around the loss that can lead to increased feelings of isolation. This meta-synthesis aimed to explore partners' experiences of perinatal death following miscarriage, stillbirth and neonatal death. A search of six electronic databases resulted in the inclusion of 18 studies involving over 300 fathers.
