2,3,7,8-Tetrachlorodibenzo-p-dioxin (dioxin; TCDD) is an environmental contaminant that elicits a variety of toxic effects, many of which are mediated through activation of the aryl hydrocarbon receptor (AhR). Interaction between AhR and the peroxisome proliferator-activated receptor-alpha (PPAR-α), which regulates fatty acid metabolism, has been suggested. Furthermore, with recognition of the prevalence of inflammatory conditions, there is current interest in the potential for inflammatory stress to modulate the response to environmental agents. The aim of this work was to assess the interaction of TCDD with hepatic inflammation modulated by fenofibrate, a PPAR-α agonist. Female, C57BL/6 mice were treated orally with vehicle or fenofibrate (250 mg/kg) for 13 days, and then were given vehicle or 30 μg/kg TCDD. Four days later, the animals received an i.p. injection of lipopolysaccharide-galactosamine (LPS-GalN) (0.05x107 EU/kg and 500 mg/kg, respectively) to incite inflammation, or saline as vehicle control. After 4 h, the mice were euthanized, and blood and liver samples were collected for analysis. Livers of animals treated with TCDD with or without LPS-GalN had increased lipid deposition, and this effect was blocked by fenofibrate. In TCDD/LPS-GalN-treated mice, fenofibrate caused an increase in plasma activity of alanine aminotransferase, a marker of hepatocellular injury. TCDD reduced LPS-GalN-induced apoptosis, an effect that was prevented by fenofibrate pretreatment. LPS-GalN induced an increase in the concentration of interleukin-6 in plasma and accumulation of neutrophils in liver. TCDD exposure enhanced the former response and inhibited the latter one. These results suggest that fenofibrate counteracts the changes in lipid metabolism induced by TCDD but increases inflammation and liver injury in this model of inflammation-TCDD interaction.
Evidence comparing the yield of chromosomal microarray analysis to noninvasive prenatal screening in pregnancies with congenital heart anomalies is currently limited.

This study aimed to examine the residual risk of clinically significant chromosomal microarray analysis results in fetuses with congenital heart defects by its various subtypes following a normal noninvasive prenatal screening.

Using a population-based, countrywide computerized database, we retrieved the reports of all pregnancies undergoing chromosomal microarray analysis because of congenital heart defects through the years 2013-2019. We examined the risk of clinically significant (pathogenic and likely pathogenic) chromosomal microarray analysis results and compared it with the results of a local cohort of low-risk pregnancies. Of 5541 fetuses, 78 (1.4%) showed abnormal results. The residual risk of abnormal chromosomal microarray analysis results was calculated using several options-trisomies 21, 18, and 13; sex chromosome aneuploidiess and genetic counselors when considering the option of diagnostic testing.
The residual risk of clinically significant chromosomal microarray analysis results in pregnancies with fetuses with congenital heart defects following normal noninvasive prenatal screening was higher than those in pregnancies with normal ultrasound in most isolated and nonisolated congenital heart defect subtypes. This information should be taken into account by obstetricians and genetic counselors when considering the option of diagnostic testing.
A recent large clinical trial demonstrated an approximately 50% decrease in the rate of postoperative infection in women who were laboring and/or had rupture of membranes for >4 hours and who received azithromycin in addition to standard preoperative antibiotic prophylaxis at the time of cesarean delivery. Given these results, our institution made a policy change in May 2017 to add azithromycin to standard preoperative prophylaxis for all cesarean deliveries.

This study aimed to evaluate the clinical effectiveness of adding azithromycin to preoperative antibiotic prophylaxis for cesarean delivery.

We conducted a before-and-after cohort study of women delivered via cesarean delivery at our institution. The preimplementation group included women who delivered from March 1, 2016, to February 28, 2017, (before an institutional practice change of adding azithromycin to standard preoperative prophylaxis), and the postimplementation group included women who delivered from September 1, 2017, to August 31, 20orioamnionitis (relative risk, 0.37 [95% confidence interval, 0.08-1.67]; data too sparse for adjusted analysis). In the subgroup of women who were not in labor, the after cohort had a statistically nonsignificant increased risk of the composite outcome in both unadjusted (relative risk, 1.53; 95% confidence interval, 0.86-2.72) and adjusted (adjusted relative risk, 1.48; 95% confidence interval, 0.83-2.65]) comparisons.

In clinical practice, the addition of azithromycin to standard preoperative antibiotic prophylaxis for cesarean delivery may have an effect size smaller than seen in the large clinical trial prompting this practice change. Extrapolation of this regimen to women not in labor may be ineffective.

Although simulation is now widely used to improve teamwork and communication, data demonstrating improvement in clinical outcomes are limited.

This study aimed to examine the clinical performance and outcomes associated with postpartum hemorrhage because of uterine atony following the implementation of a multidisciplinary simulation program.

This was a prospective observational study of response to postpartum hemorrhage because of uterine atony in an academic medical center before (epoch 1 July 2017-June 2018) and after (epoch 2 July 2019-June 2020) implementing a multidisciplinary simulation program. A total of 22 postpartum hemorrhage simulations were performed from July 2018 to June 2019 involving more than 300 nursing, obstetrical, and anesthesia providers. The simulation program focused on managing postpartum hemorrhage events and improving teamwork and communication of the multidisciplinary teams. To evaluate the clinical effectiveness of the simulation program, the primary outcome was response to postpartum hemorrhage defined as the time from the administration of uterotonic medications to transfusion of the first unit of blood in the first 12 hours following delivery, comparing epoch 2 to epoch 1 following the implementation of a simulation program.
