Association of Food Deserts and COVID-19 Severity in Pregnancy as Reflected by Need for Hospitalization.

BACKGROUND: Socioeconomic disparities play an important role in disease epidemiology and outcomes in pregnancy. OBJECTIVE: The objective was to evaluate whether pregnant women with COVID-19 living in a food desert, are at increased risk of more severe disease reflected by symptoms at presentation and need for hospitalization. METHODS: In this retrospective observational study, the electronic medical records of all pregnant patients with documented SARS-CoV-2 infection were reviewed. Food deserts were defined by the USDA and the patient's residence was mapped on the Food Access Research Atlas to determine whether each patient lived within a food desert. Comparisons between those with documented symptomatic COVID-19 required hospitalization to those with documented COVID-19 without need for hospitalization were made using univariate analysis and multivariable logistic regression analysis. RESULTS: The cohort consisted of 129 pregnant patients with COVID-19, with 59.7% (n = 77) asymptomatic and 33.3% (n = 43) requiring admission due to disease severity. The majority were Hispanic (70.5%), and obese (median BMI 31.91 kg/m2), with 33.3% living in a food desert. Patients with disease severity necessitating admission were significantly more likely to reside in a food desert (46.5% vs. 27.9%, P 0.037, OR 2.246, 95% CI 1.048-4.814). No other significant differences were identified on univariate. Multivariable binary logistic regression modeling confirmed food desert residence to be the only independent predictor of more severe COVID-19. CONCLUSION FOR PRACTICE: There is a strong association between living in a food desert and the development of symptomatic COVID-19 requiring hospitalization in pregnancy.

MRSA screening: incidence and maternal postpartum outcomes in an obstetric population at a tertiary care center.

PURPOSE: To assess the incidence of MRSA positive patients in pregnancy, as well as the postpartum outcomes in MRSA positive patients. METHODS: This is a retrospective cohort study of women who underwent universal MRSA universal at a tertiary medical center. A MRSA swab was routinely collected as part of the patient's prenatal care at 35-37 weeks gestation or on admission to labor and delivery. Demographic information and decolonization antibiotics were collected by electronic medical record review, using ICD-9 codes. Outcome data were collected, including mode of delivery, hospital length of stay, endometritis, wound cellulitis, and wound infection. p < 0.05 was considered significant. A univariate logistic regression and a multivariable binary logistic regression model were used to analyze the strength of association between outcomes and MRSA status. Statistical analysis was performed with SAS, version 9.4. RESULTS: The incidence of MRSA during the 4 year study period was 1.9% (82 MRSA positive out of 4369 total patients). 90.2% (74/82) of MRSA positive patients received decolonization antibiotics. No difference was noted in mode of delivery. Logistic regression failed to identify any significant differences in other relevant outcomes for MRSA positive women including endometritis 1.1 (0.1-17.5) [positive 0, versus negative 0.6% (n = 24)], wound cellulitis 5.9 (0.4-82.1) positive 0, versus negative 0.1% (Gorwitz et al. in J Infect Dis 197:1226-1234, 2008) and wound infection 3.3 (0.6-16.9) [positive 1.2%, versus negative 0.5% ( in Am J Infect Control 32:470-85, 2004)] when compared to MRSA negative women. CONCLUSION: When universal MRSA screening was performed at an academic tertiary care center, the overall incidence of MRSA was low. MRSA positive and subsequently decolinzed patients did not have any identified increase in postpartum infectious morbidity, as compared to MRSA negative patients.

Preventing caesarean section wound complications: use of a silver-impregnated antimicrobial occlusive dressing.

OBJECTIVE: To investigate the role of an adherent soft silicone antimicrobial occlusive foam silver-impregnated dressing for reduction of surgical site infections (SSI) in primary low-transverse caesarean section (1°LTCS) delivery. METHOD: Women aged 18-45 years admitted to the labour and delivery or the antepartum unit undergoing a 1°LTCS were recruited. Exclusion criteria included repeat caesarean, vertical skin incision, intrapartum fever and closure with staples. Consented participants delivered by scheduled or unscheduled 1°LTCS received the silver-impregnated dressing. Those who declined to participate and were delivered by scheduled or unscheduled caesarean received a standard gauze with tape dressing (controls). Surgical preparation and preoperative antibiotics were administered as per hospital policy. RESULTS: A total of 362 participants were consented for use of the silver-impregnated dressing, with 190 participants undergoing 1°LTCS, of whom 185 were included in the final analysis. Of those who declined to participate, 190 ultimately underwent 1°LTCS during the same time period. Cases and controls were similar in demographics, body mass index, diabetes status, labour and procedure length, and tobacco use. The overall incidence of SSI was 3.7%. A 50% reduction in incidence of SSI was observed in the silver-impregnated dressing group compared with control group (2.7% versus 4.7%, respectively), but this was not statistically significant (p=0.08; odds ratio 0.55; 95% confidence interval: 0.18-1.67). CONCLUSION: Among women undergoing 1°LTCS with subcuticular closure of a transverse incision, use of a silver-impregnated dressing reduced the rate of SSI by >50% but was not statistically significant.

Placenta previa: an outcome-based cohort study in a contemporary obstetric population.

OBJECTIVE: The objective of the study is to characterize the maternal and neonatal morbidities of women with placenta previa. STUDY DESIGN: This retrospective group study used the Consortium on Safe Labor electronic database, including 12 clinical centers, and 19 hospitals. Patients with placenta previa noted at the time of delivery were included. Maternal and neonatal variables were compared to a control group of women undergoing cesarean delivery with no previa. Logistic regression and general linear regression were used for the analysis, with p < 0.05 significance. RESULTS: There were 19,069 patients in the study: 452 in the placenta previa group and 18,617 in the control group. Neonates born to mothers with placenta previa had lower gestational ages and birth weights. In univariate analysis only, these neonates were at increased risk of lower 5 min Apgar scores, neonatal intensive care unit admission, anemia, respiratory distress syndrome, mechanical ventilation, and intraventricular hemorrhage. There was no association of placenta previa with small for gestational age infants, congenital anomalies or death. As previously shown, women with placenta previa have significantly more maternal morbidities. CONCLUSION: Increased maternal morbidity was noted; however, only those neonatal morbidities associated with preterm delivery occurred in the placenta previa group.

Laparoscopic appendectomy in women without identifiable pathology undergoing laparoscopy for chronic pelvic pain.

OBJECTIVES: To assess the effectiveness of appendectomy in women undergoing laparoscopy for chronic pelvic pain without identifiable pathology. METHODS: This retrospective cohort study included women aged 15 to 50 years who underwent laparoscopic surgery for chronic pelvic pain without identifiable pathology. The cohort was divided into 2 groups: women who underwent appendectomy and women who had not undergone appendectomy at laparoscopic surgery. Postoperative pain was assessed at 6-week follow-up and by subsequent mailed questionnaire. RESULTS: Women who underwent appendectomy (n = 19) were significantly more likely to report improvement in pain at 6-week follow-up than women who did not undergo appendectomy (n = 76) (93% vs 16%; P < .001). Thirty-six patients (38%) responded to the questionnaire at a median of 4.2 years after surgery, when the median change (improvement) in reported pain was greater in the appendectomy group than in the nonappendectomy group. CONCLUSION: Appendectomy is effective therapy for patients with chronic pelvic pain of unknown etiology who are undergoing laparoscopy.

Eclampsia: Maternal and neonatal outcomes.

The objective of our study is to define the maternal and neonatal outcomes associated with eclampsia. This retrospective cohort study was performed using the Consortium on Safe Labor, database from 12 clinical centers, including 19 hospitals, from 2002-2008. All patients admitted with a diagnosis of eclampsia or seizure in labor and delivery or postpartum were included in the analysis. Patients with history of seizure disorder were excluded. Maternal and neonatal outcomes were compared to outcomes of women with preeclampsia and their neonates. Statistical analyses were performed using SAS. Chi square and t-test were used for categorical and continuous variables, respectively. Logistic regression and general linear regression were used to calculate odds ratios and 95% confidence intervals. p<0.05 was considered significant. The eclampsia prevalence was 0.08% (n=191) in our population; the preeclampsia cohort had 7012 women. There were significantly more eclamptic women (49%) delivered by cesarean section, as compared to preeclamptic women (36%), OR 1.7 (1.28-2.28). These women were more likely to have an ICU admission OR 12.9 (7.0-23.7). The mean gestational ages and birthweights were lower in the neonates of the eclampsia group. A multivariate analysis revealed that low cord arterial pH, low 5min Apgar score, respiratory distress syndrome OR 5.5, (1.11-27.66) and seizures OR 10.3 (3.12-33.68), p<0.05, were significantly elevated in the eclampsia cohort. The prevalence of eclampsia in our contemporary obstetrics population was 0.08%. Both mothers as well as neonates of eclamptics are at significant risk for complications due to their illness.

Resolution of complete placenta previa: does prior cesarean delivery matter?

OBJECTIVES: The purpose of this study was to prospectively assess the rate of resolution of complete placenta previa diagnosed at second-trimester sonography in patients with and without previous cesarean delivery. METHODS: This prospective study evaluated patients at 3 institutions with complete placenta previa diagnosed at second-trimester screening sonography. All patients were followed with sonography every 4 to 6 weeks until either resolution of the previa or delivery occurred. Patients with persistent/nonresolving complete placenta previa underwent cesarean delivery. RESULTS: A total of 67 patients were enrolled in the study; 18 patients had a prior cesarean delivery. Resolution of placenta previa occurred in 11 of 18 patients (61%) with a prior cesarean delivery, whereas 44 of 49 patients (90%) without a prior cesarean delivery had resolution of placenta previa (P = .012, Fisher exact test). Placental location per se (anterior or posterior) was not associated with resolution of placenta previa (P = .22). Complete placenta previa persisted to delivery in 5 of 9 patients (56%) with a prior cesarean delivery and an anterior placental location. CONCLUSIONS: This prospective study indicates that patients with a prior cesarean delivery and complete placenta previa diagnosed at second-trimester sonography are less likely to have subsequent resolution of the previa when compared to those without a history of cesarean delivery.
