Exposure to Infection in Pregnancy May Increase Risk of Autism, Depression

Autism spectrum disorder and depression were more common in Swedish children and adults born to mothers who had experienced infections during pregnancy while hospitalized, according to astudy published inJAMA Psychiatry. The study is one of the first to evaluate a generalized effect of infection and inflammation during pregnancy on a broad spectrum of psychiatric disorders, wrote the authors.“The developmental origins of mental illness are incompletely understood,” wrote Benjamin al-Haddad, M.D., M.Sc., Ph.D., of the Seattle Children’s Hospital and University of Washington, Seattle, and colleagues. “Maternal and fetal inflammatory responses to infection may alter fetal neurodeve lopment, as suggested in some children with autism.”The researchers used population-based registries to observe approximately one million children born between 1973 and 2014 in Sweden for up to 41 years. Infection and psychiatric diagnoses were derived using codes from hospitalizations. Hospitalization categories for pregnant women included any infection, severe infections, and urinary tract infections (UTIs) to further investigate whether the magnitude of risk to children differed by the type and severity of infection.The risks of autism and depression increased 79% and 24%, respectively, among children and adults exposed to any maternal infection during pregnancy. Similar results were obtained for exposure to severe infections and UTIs, suggesting that type and severity...

Conclusions: This review results revealed a low utilization of postnatal care service. Antenatal care service utilization has a positive effect on postnatal care service utilization. Policymakers and programmers better considered more antenatal care service use as one strategy of enhancing the utilization of postnatal care service. PMID: 33029402 [PubMed - in process]

Authors: Debelew GT Abstract Despite several efforts globally, the problem of perinatal mortality remained an unsolved agenda. As a result, it continued to be an essential part of the third sustainable development goals to end preventable child deaths by 2030. With a rate of 33 per 1000 births, Ethiopia has the highest level of perinatal mortality in the world. Thus, determining the magnitude and identifying the determinants are very crucial for evidence-based interventions. A community-based longitudinal study was conducted in Southwest Ethiopia among 3474 pregnant women to estimate the magnitude of perinatal mort...

This study was aimed at assessing the magnitude of induced abortion and associated factors among students in Hawassa University, southern region, Ethiopia, 2019. Methods: An institutional-based cross-sectional study was conducted among a total of 422 students selected on the bases of a probability simple random sampling method. A pretested structured questionnaire was used to collect data. Analysis was made with SPSS 20. Descriptive summary and inferential statistics (binary logistic regression) were used with a 95% CI and P value of less than 5% as a level of significance. Findings were presented in tables, figure, an...

Conclusions: (1) Data at our center suggests at least a regional implementation gap in GBS screening and IAP. (2) The decline in the resistance rate ofE. coli for all antimicrobial substances might indicate that the reduction of prenatal antibiotics use is beneficial and that neonatal antibiotic stewardship programs should include pregnant women as well.What is Known:• GBS screening and intrapartum antibiotic prophylaxis led to a 32%-reduction in GBS disease in Germany with a 0.75 (92:122) ratio of early-onset disease to late-onset disease in 2009–2010.• Prenatal antibiotic use might increase the risk of E....

In this study, we explored its health effects on the female offspring of mice that had been exposed during pregnancy. We found that exposure of pregnant mice to nitenpyram resulted in decreased levels of serum triglycerides, total cholesterol, and glucose in female offspring, and additional research uncovered gut microbiota disturbances, accompanied by abnormal fecal metabolic profiles. Based on Pearson correlation analysis, we found that decreased abundance of Lactobacillus may play the most critical role, and changes in gut bacterial purine metabolism, BCAAs metabolism, and the TCA cycle are all closely related to the ab...
