To ascertain the frequency of maternal and neonatal complications, as well as maternal disease severity, in pregnancies affected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) ...infection.
MEDLINE, Ovid, ClinicalTrials.gov, MedRxiv, and Scopus were searched from their inception until April 29, 2020. The analysis was limited to reports with at least 10 pregnant patients with SARS-CoV-2 infection that reported on maternal and neonatal outcomes.
Inclusion criteria were pregnant women with a confirmed diagnosis of SARS-CoV-2 infection. A systematic search of the selected databases was performed by implementing a strategy that included the MeSH terms, key words, and word variants for "coronavirus," "SARS-CoV-2," "COVID-19," and "pregnancy.r The primary outcomes were maternal admission to the intensive care unit (ICU), critical disease, and death. Secondary outcomes included rate of preterm birth, cesarean delivery, vertical transmission, and neonatal death. Categorical variables were expressed as percentages with number of cases and 95% CIs.
Of the 99 articles identified, 13 included 538 pregnancies complicated by SARS-CoV-2 infection, with reported outcomes on 435 (80.9%) deliveries. Maternal ICU admission occurred in 3.0% of cases (8/263, 95% CI 1.6-5.9) and maternal critical disease in 1.4% (3/209, 95% CI 0.5-4.1). No maternal deaths were reported (0/348, 95% CI 0.0-1.1). The preterm birth rate was 20.1% (57/284, 95% CI 15.8-25.1), the cesarean delivery rate was 84.7% (332/392, 95% CI 80.8-87.9), the vertical transmission rate was 0.0% (0/310, 95% CI 0.0-1.2), and the neonatal death rate was 0.3% (1/313, 95% CI 0.1-1.8).
With data from early in the pandemic, it is reassuring that there are low rates of maternal and neonatal mortality and vertical transmission with SARS-CoV-2. The preterm birth rate of 20% and the cesarean delivery rate exceeding 80% seems related to geographic practice patterns.

To compare the risk of intrauterine fetal death (20 weeks of gestation or later) and neonatal death among individuals who tested positive for severe acute respiratory syndrome coronavirus 2 ...(SARS-CoV-2) compared with those who tested negative for SARS-CoV-2 on admission for delivery.
MEDLINE, Ovid, EMBASE, Cumulative Index to Nursing and Allied Health, and Cochrane Library were searched from their inception until July 17, 2020. Hand search for additional articles continued through September 24, 2020. ClinicalTrials.gov was searched on October 21, 2020.
The inclusion criteria were publications that compared at least 20 cases of both pregnant patients who tested positive for SARS-CoV-2 on admission to labor and delivery and those who tested negative. Exclusion criteria were publications with fewer than 20 individuals in either category or those lacking data on primary outcomes. A systematic search of the selected databases was performed, with co-primary outcomes being rates of intrauterine fetal death and neonatal death. Secondary outcomes included rates of maternal and neonatal adverse outcomes.
Of the 941 articles and completed trials identified, six studies met criteria. Our analysis included 728 deliveries to patients who tested positive for SARS-CoV-2 and 3,836 contemporaneous deliveries to patients who tested negative. Intrauterine fetal death occurred in 8 of 728 (1.1%) patients who tested positive and 44 of 3,836 (1.1%) who tested negative (P=.60). Neonatal death occurred in 0 of 432 (0.0%) patients who tested positive and 5 of 2,400 (0.2%) who tested negative (P=.90). Preterm birth occurred in 95 of 714 (13.3%) patients who tested positive and 446 of 3,759 (11.9%) who tested negative (P=.31). Maternal death occurred in 3 of 559 (0.5%) patients who tested positive and 8 of 3,155 (0.3%) who tested negative (P=.23).
The incidences of intrauterine fetal death and neonatal death were similar among individuals who tested positive compared with negative for SARS-CoV-2 when admitted to labor and delivery. Other immediate outcomes of the newborns were also similar among those born to individuals who tested positive compared with negative for SARS-CoV-2.

A systematic review was performed to compare adverse maternal and neonatal outcomes among pregnant patients with gunshot wounds (GSW) to the abdominopelvic vs other region(s) at > 20 weeks gestation. ...A search of Medline Ovid, Elsevier Embase, EBSCO CINAHL, and Cochrane Library in July 2022 and reference searches resulted in 1742 studies, which were screened. The 41 included studies reported outcomes for 59 pregnant patients with GSW, of which 31 (52.5%) had an isolated abdominopelvic GSW and 28 (47.5%) had an extremity, thorax, head/neck, back/spine, poly-site, or other/unknown GSW. Stillbirth occurred in 26.7% of abdominopelvic GSW and 26% of non-abdominopelvic GSW. Maternal death occurred in 3.7% of abdominopelvic GSW and 10.7% of non-abdominopelvic GSW. Neonatal death occurred in 9.1% of abdominopelvic GSW and 5.3% of non-abdominopelvic GSW. Further research is needed to standardize the approach for the evaluation and management of patients with GSW in pregnancy.
Background
Better understanding of the factors associated with formula feeding during the hospital stay can help in identifying potential lactation problems and promote early intervention. Our aim ...was to ascertain factors associated with exclusive formula feeding in newborns of low‐risk pregnancies.
Methods
A population‐based, retrospective study using the United States vital statistics datasets (2014‐2018) evaluating low‐risk pregnancies with a nonanomalous singleton delivery from 37 to 41 weeks. People with hypertensive disorders, or diabetes, were excluded. Primary outcome was newborn feeding (breast vs exclusive formula feeding) during hospital stay. Adjusted relative risks (aRRs) with 95% confidence intervals (CI) were calculated.
Results
Of the 19 623 195 live births during the study period, 11 605 242 (59.1%) met inclusion criteria and among them, 1 929 526 (16.6%) were formula fed. Factors associated with formula feeding included: age < 20 years (aRR 1.31 95% CI 1.31‐1.32), non‐Hispanic Black (1.42, 1.41‐1.42), high school education (1.69, 1.69‐1.70) or less than high school education (1.94, 1.93, 1.95), Medicaid insurance (1.52, 1.51, 1.52), body mass index (BMI) < 18.5 (1.10, 1.09‐1.10), BMI 25‐29.9 (1.09, 1.09‐1.09), BMI 30‐34.9 (1.19, 1.19‐1.20), BMI 35‐39.9 (1.31, 1.30‐1.31), BMI ≥ 40 (1.43, 1.42‐1.44), multiparity (1.29, 1.29‐1.30), lack of prenatal care (1.49, 1.48‐1.50), smoking (1.75, 1.74‐1.75), and gestational age (ranged from 37 weeks 1.44, 1.43‐1.45 to 40 weeks 1.11, 1.11‐1.12).
Conclusions
Using a large cohort of low‐risk pregnancies, we identified several modifiable factors associated with newborn feeding (eg, prepregnancy BMI, access to prenatal care, and smoking cessation). Improving the breast feeding initiation rate should be a priority in our current practice to ensure equitable care for all neonates.
Standardization of procedures improves outcomes. Though systematic reviews have summarized the evidence-based steps (EBS) of cesarean delivery (CD), their bundled implementation has not been ...investigated.
In this pre- and post-implementation trial, we sought to ascertain if bundled EBS of CD, compared to surgeon’s preference, improves outcomes.
A StaRI (Standards for Reporting Implementation Studies) compliant, multi-center pre- and post-implementation trial at 4 teaching hospitals was conducted. The pre-implementation period consisted of CD done based on the physicians’ preferences for 3 months; educational intervention (e.g., didactics, badge cards, posters, video) occurred at the 4th month. CDs in post-implementation period employed the bundled EBS. A pre-planned 10% randomized audit of both groups assessed adherence and uptake of EBS. The primary outcome was a composite maternal morbidity (CMM), which included estimated blood loss > 1,000 mL, blood transfusion, endometritis, post-partum fever, wound complications, sepsis, thrombosis, ICU admission, hysterectomy, or death. The secondary outcome was a composite neonatal morbidity (CNM) and some of its components were 5-min Apgar score < 7, positive pressure oxygen use, hypoglycemia, or sepsis. A priori Bayesian sample size calculation indicated 700 CD in each group was needed to demonstrate 20% relative reduction (from 15% to 12%) of CMM with 75% certainty. Bayesian logistic regression with neutral priors was used to calculate likelihood of net-improvement in adjusted relative risk (aRR) with 95% credible intervals (CrI).
A total of 1,425 consecutive CD (721 in pre- and 704 in post-implementation group) were examined. Audited data indicated that the baseline EBS utilization rate during the pre-implementation period was 79%; after the implementation bundled EBS of CD the audited adherence was 89%—an uptake of 10.0% of the EBS. In four aspects, the maternal characteristics differed significantly in the pre- and post-implementation periods: race/ethnicity, hypertensive disorder, and the relative contribution of the 4 centers to the cohorts and the gestational age at delivery, but the indications for CD and whether its duration was < versus > 60 min did not. The rates of CMM in the pre- and post-implementation groups were 26% and 22%, respectively (aRR, 0.88; 95% CrI, 0.73-1.04), with a 94 % Bayesian probability of a reduction in CMM. The CNM occurred in 37% of the pre- and in 41% of the post-implementation group (aRR, 1.12; 95% CrI 0.98-1.39), with a 95% Bayesian probability of worsening in CNM. When CMM were segregated by preterm (<37 wks) and term (> 37 weeks) CD, the improvement in maternal outcomes persisted; when CNM were segregated by gestational age subgroupsthe potential for worsening neonatal outcomes persisted as well.
Standardization of the evidence-based bundled steps of cesarean delivery resulted in a modest reduction of the composite maternal outcome; however, a paradoxical increase in neonatal composite morbidity was noted. Although individual evidence-based steps may be of value, while awaiting additional intervention trials a formal bundling of such steps is currently not recommended.
Electronic fetal monitoring assesses fetal health during the prenatal and intrapartum process. Intermittent auscultation does not detect key elements of fetal risk, such as beat-to-beat variability. ...Family medicine obstetric fellowships have contributed new knowledge to this process by articulating a method of analysis that builds on evidence-based recommendations from the American College of Obstetrics and Gynecology as well as the National Institute of Child Health and Development. This article summarizes the development, interpretation, and management of electronic fetal heart rate patterns and tracings.
