RESUMO
OBJECTIVE: Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), ranges from asymptomatic to severe infection. We aimed to compare the prevalence of COVID-19 in asymptomatic pregnant versus nonpregnant women in order to establish recommendations for a COVID-19 screening strategy. METHODS: A prospective multicenter cohort study was conducted. Asymptomatic pregnant or nonpregnant women after March 2020 (the time when COVID-19 was first detected in north Israel) were tested for SARS-CoV-2 using nasopharyngeal reverse transcription polymerase chain reaction test, anti-nucleocapsid IgG, and anti-spike IgG. Diagnosis was made if at least one test result was positive. Pregnant women were tested between 34 and 42 weeks, mostly at birth. RESULTS: Among the 297 participating women, 152 were pregnant and 145 were nonpregnant. The prevalence of asymptomatic COVID-19 was similar between the groups (4 [2.6%] and 8 [5.5%], respectively; P = 0.2). All women with COVID-19 delivered healthy appropriate-for-gestational-age babies without malformations, at term. CONCLUSIONS: The rate of asymptomatic COVID-19 in pregnant women is low and comparable to the rate among nonpregnant women. Pregnancy outcomes are favorable. Future screening programs should consider that one of 25 screened asymptomatic women will be positive.

This study aimed to examine the effect of antibiotic prophylaxis (AP) given within 30 compared to 30-60 min before skin incision on the incidence of infectious morbidity after cesarean delivery (CD). A retrospective cohort study was conducted at a single institution on data between 2014 and 2018. Women who delivered by CD were divided into two groups according to AP timing before skin incision: group 1 within 30 min, and group 2 from 30 to 60 min. The primary outcome was the incidence of any infectious morbidity. Overall, 2989 women were eligible: 2791 in group 1 and 198 in group 2. The primary composite outcome occurred in 125 women (4.48%) in group 1 and 8 women (4.04%) in group 2 (OR, 1.11; 95% CI 0.54-2.31; P = 0.77). The rate of surgical site infection only, was 1.08% in group 1 and 0.51% in group 2 (OR, 2.13; 95% CI 0.29-15.70; P = 0.72). The incidence was comparable between the groups in a separate sub-analysis restricted to laboring CDs and obese women. The rate of infectious morbidity was similar among women who received AP within 30 min and from 30 to 60 min before skin incision.

INTRODUCTION: Hemoconcentration has been proposed as a surrogate for successful decongestion in acute heart failure (AHF). The aim of the present study was to evaluate the relationship between hemoconcentration and clinical measures of congestion. METHODS AND RESULTS: We studied 704 patients with AHF and volume overload. A composite congestion score was calculated at admission and discharge, with a score >1 denoting persistent congestion. Hemoconcentration was defined as any increase in hematocrit and hemoglobin levels between baseline and discharge. Of 276 patient with hemoconcentration, 66 (23.9%) had persistent congestion. Conversely, of 428 patients without hemoconcentration, 304 (71.0%) had no clinical evidence of congestion. Mean hematocrit changes were similar with and without persistent congestion (0.18 ± 3.4% and -0.19 ± 3.6%, respectively; P = .17). There was no correlation between the decline in congestion score and the change in hematocrit (P = .93). Hemoconcentration predicted lower mortality (hazard ratio 0.70, 95% confidence interval 0.54-0.90; P = .006). Persistent congestion was associated with increased mortality independent of hemoconcentration (Ptrend = .0003 for increasing levels of congestion score). CONCLUSIONS: Hemoconcentration is weakly related to congestion as assessed clinically. Persistent congestion at discharge is associated with increased mortality regardless of hemoconcentration. Hemoconcentration is associated with better outcome but cannot substitute for clinically derived estimates of congestion to determine whether decongestion has been achieved.

Worsening renal function (WRF) and congestion are inextricably related pathophysiologically, suggesting that WRF occurring in conjunction with persistent congestion would be associated with worse clinical outcome. We studied the interdependence between WRF and persistent congestion in 762 patients with acute decompensated heart failure (HF). WRF was defined as ≥0.3 mg/dl increase in serum creatinine above baseline at any time during hospitalization and persistent congestion as ≥1 sign of congestion at discharge. The primary end point was all-cause mortality with mean follow-up of 15 ± 9 months. Readmission for HF was a secondary end point. Persistent congestion was more common in patients with WRF than in patients with stable renal function (51.0% vs 26.6%, p <0.0001). Both persistent congestion and persistent WRF were significantly associated with mortality (both p <0.0001). There was a strong interaction (p = 0.003) between persistent WRF and congestion, such that the increased risk for mortality occurred predominantly with both WRF and persistent congestion. The adjusted hazard ratio for mortality in patients with persistent congestion as compared with those without was 4.16 (95% confidence interval [CI] 2.20 to 7.86) in patients with WRF and 1.50 (95% CI 1.16 to 1.93) in patients without WRF. In conclusion, persisted congestion is frequently associated with WRF. We have identified a substantial interaction between persistent congestion and WRF such that congestion portends increased mortality particularly when associated with WRF.
