Severe acute respiratory syndrome coronavirus 2: a canary in the coal mine for public safety net hospitals.

Background: The coronavirus disease 2019 pandemic has exposed disproportionate health inequities among underserved populations, including refugees. Public safety net healthcare systems play a critical role in facilitating access to care for refugees and informing coordinated public health prevention and mitigation efforts during a pandemic.

Objective: This study aimed to evaluate the prevalence ratios of severe acute respiratory syndrome coronavirus 2 infection between refugee women and nonrefugee parturient patients admitted to the hospital for delivery.

Effect of obesity on preterm delivery prediction by transabdominal recording of uterine electromyography.

Objective: It has been shown that noninvasive uterine electromyography (EMG) can identify true preterm labor more accurately than methods available to clinicians today. The objective of this study was to evaluate the effect of body mass index (BMI) on the accuracy of uterine EMG in predicting preterm delivery.

Materials And Methods: Predictive values of uterine EMG for preterm delivery were compared in obese versus overweight/normal BMI patients.

Management of rhinosinusitis during pregnancy: systematic review and expert panel recommendations.

Background: Management of rhinosinusitis during pregnancy requires special considerations.

Objectives: 1. Conduct a systematic literature review for acute and chronic rhinosinusitis (CRS) management during pregnancy.

Paper gestational age wheels are generally inaccurate.

Objective: To compare the estimated date of confinement of paper gestational wheels to the estimated date of confinement of APPs wheels using a standard last menstrual period.

Methods: Obstetric providers were asked for their gestational wheels. The last menstrual period was set at Jan.

Costs of unnecessary admissions and treatments for "threatened preterm labor".

Objective: Cervical length (CL) of 3 cm or greater has been shown to have a 97-99% negative predictive value for preterm delivery in women with threatened preterm labor. Consequently, hospitalization and treatment are not indicated in these patients. We analyzed how often patients with a CL of 3 cm or greater are still being admitted and treated for preterm labor and how much this contributes to the economic burden of preterm labor hospitalizations.

Progestin treatment for the prevention of preterm birth.

Progestin supplementation appears to be a promising approach to both preventing initiation of preterm labor and treating it once it is already established, given the role of progesterone in maintaining pregnancy, as well as support from basic and clinical research. Progesterone and 17α-hydroxyprogesterone acetate slow the process of cervical ripening, and this is the rationale for prophylactic long-term progestin supplementation mostly studied so far. However, progesterone (but not 17α-hydroxyprogesterone acetate) also inhibits myometrial activity even after the cervix has already ripened.

Additive inhibitory effects of progesterone and sodium nitroprusside on uterine contractility during pregnancy.

Progesterone (P4) and nitric oxide (NO) suppress uterine contractility (CTX). This study compares the effects of P4 to sodium nitroprusside (SNP, an NO donor) and their combination on human CTX of term/preterm and labor/nonlabor tissues. Uterine tissues (n = 128) from women (n = 28) undergoing Cesarean were suspended in organ baths.

Use of uterine electromyography to diagnose term and preterm labor.

Current methodologies to assess the process of labor, such as tocodynamometry or intrauterine pressure catheters, fetal fibronectin, cervical length measurement and digital cervical examination, have several major drawbacks. They only measure the onset of labor indirectly and do not detect cellular changes characteristic of true labor. Consequently, their predictive values for term or preterm delivery are poor.

Noninvasive uterine electromyography for prediction of preterm delivery.

Objective: Power spectrum (PS) of uterine electromyography (EMG) can identify true labor. EMG propagation velocity (PV) to diagnose labor has not been reported. The objective was to compare uterine EMG against current methods to predict preterm delivery.

Intimate partner violence and its implication for pregnancy.

Intimate partner violence (IPV) is a common occurrence in pregnancy and results in an increased risk of adverse outcomes. Homicide may be the most common cause of maternal death. Women who are pregnant and the victims of IPV have high rates of stress, are more likely to smoke or use other drugs, deliver a preterm or low birth weight infant, have an increase in infectious complications, and are less likely to obtain prenatal care.

Cesarean delivery and respiratory distress syndrome: does labor make a difference?

Objective: The purpose of this study was to determine if cesarean delivery is a risk factor for respiratory distress syndrome (RDS) and if this risk is modified by labor before cesarean.

Study Design: This population-based case-control study compared 4778 cases of RDS to 5 times as many controls.

Results: Unadjusted, cesarean delivery was associated with RDS, odds ratio (OR) 3.
