Nasopharyngeal SARS-CoV-2 load and perinatal outcomes after maternal infection diagnosed close to delivery.

BACKGROUND: The occurrence of COVID-19 during the pregnancy can cause several negative maternal and neonatal outcomes. Nasopharyngeal viral load is associated with inflammatory markers and might influence the disease severity in non-pregnant patients, but there are no data about the relationship between viral load and perinatal outcomes in pregnant patients. OBJECTIVE: To investigate the hypothesis that nasopharyngeal SARS-CoV-2 load (estimated with real-time polymerase chain reaction delta cycle (ΔCt), measured in hospital clinical laboratories) is associated with perinatal outcomes, when COVID-19 is diagnosed in the third trimester of pregnancy. STUDY DESIGN: International, retrospective, observational, multi-center, cohort study enrolling 390 women (393 neonates, three pairs of twins), analyzed with multivariate generalized linear models with skewed distributions (gamma) and identity link. The analyses were conducted for the whole population and then followed by a subgroup analysis according to the clinical severity of maternal COVID-19. RESULTS: The estimated viral load in maternal nasopharynx is not significantly associated with gestational age at birth (adjusted B: -0.008 (95%CI: -0.04; 0.02); p = 0.889), birth weight (adjusted B: 4.29 (95%CI: -25; 35); p = 0.889), weight Z-score (adjusted B: -0.01 (95%CI: -0.03; 1); p = 0.336), 5' Apgar scores (adjusted B: -0. -9.8e-4 (95%CI: -0.01; 0.01); p = 0.889), prematurity (adjusted OR: -0.97 (95%CI: 0.93; 1.03); p = 0.766) and the small for gestational age status (adjusted OR: 1.03 (95%CI: 0.99; 1.07); p = 0.351). Similar results were obtained in subgroup analyses according to COVID-19 clinical severity. CONCLUSIONS: The estimated maternal nasopharyngeal viral load in pregnant women affected by COVID-19 during the third trimester is not associated with main perinatal outcomes.

The experience of women who delivered during the first wave of COVID-19 pandemic in Belgium: a retrospective study.

BACKGROUND: The lockdown caused by the COVID-19 pandemic has imposed some restrictions on hospital activities, requiring medical staff to find efficient alternatives to ensure adequate medical care for patients. OBJECTIVE: This study aimed to investigate the experience of pregnant women who delivered during the first wave of COVID-19, and to evaluate the impact of COVID-19-related restrictions. STUDY DESIGN: This was a retrospective multicenter study. All pregnant women who delivered a live infant between March 20, 2020 and June 20, 2020 were evaluated using a 35-item survey at 1 year following delivery. Each patient was contacted via 3 modalities. Patients who reported that their prenatal follow-up was interrupted were compared with those who reported that their prenatal follow-up was unchanged. Among 1096 patients who delivered a live infant across the 3 participating centers during the study period, 389 responses were needed for an estimated margin of error of 4%. RESULTS: A total of 469 of 1096 (42.8%) patients answered the survey, of whom 151 (32.2%) reported that the follow-up of their pregnancy was interrupted (exposed group) and 318 (67.8%) reported that their follow-up was maintained as normal (unexposed group). The rate of presentation to the emergency department was higher in the exposed group than in the unexposed group (P=.001). The level of dissatisfaction was also higher in the exposed group, and patients in this group would have postponed their pregnancy if they had known about the pandemic in advance (P<.001 and P=.001, respectively). CONCLUSION: Interruption and modification of antenatal follow-up in pregnant women is associated with patient dissatisfaction and increased presentation to the emergency department.

Influence of bingo halls temporary closure due to Covid-19 on gamblers' reported perceptions and behaviours

Background: In 2020, the Covid forced the shutdown of Bingo halls for a few months in the province of Quebec, Canada. This communication describes some changes it had on the clientele of bingo players, comprised mainly of women who were retired. Method: A longitudinal design served to examine reported behaviours and perceptions of Bingo players on different variables including Canadian Problem Gambling Index (CPGI) scores, consequences on different life aspects, internet gambling activity and money spent on other forms of gambling than bingo. Graduate students conducted phone interviews on two occasions: (1) during the summer of 2019 and (2) during the summer of 2020, three months after the bingo halls closure (n = 211). Results: At follow-up, as compared to pre-closure, bingo players were less numerous in proportion to report moderate to high risks of problem gambling and more numerous to gamble on the Internet. At both measures, the majority of players did not report negative consequences on most aspects of their life. There was no difference between measures on weekly money spent on other gambling activities than bingo. Conclusion: Based on this longitudinal study, gambling characteristics reported by Quebec participants playing in bingo sites were different after bingo halls closure. A discussion will explore the important links between money spent in bingo halls and the CPGI categorisation of bingo player. The discussion will also identify study limitations.

PSYCHOLOGICAL EFFECT OF COVID-19 PANDEMIC AMONG WOMEN UNDERGOING INFERTILITY CARE, A FRENCH COHORT - PSYCOVART

OBJECTIVE: To assess psychological state of women who experienced postponement of ART care during the first COVID-19 wave in a French public ward of reproductive medicine. MATERIALS AND METHODS: An online anonymous survey was emailed between July and August 2020 to all women whose infertility care have been delayed at the beginning of the COVID-19 pandemic. Anxiety, depression, and stress were assessed using Hospital Anxiety and Depression Scale (HADS) and Perceived Stress Scale (PSS-10). Feelings about COVID- 19 outbreak, lockdown and suspension of fertility care were assessed by Multiple- Choice Questions and Visual Analog Scales. RESULTS: 435 women answered to the survey (response rate 34,6%). Mean levels of the HADS-A (anxiety), HADS-D (depression) and PSS10 were respectively 7,58(±3,85), 4,51(±3,48), and 27(±6,75). Prevalence of stress was 50,8% and almost half of women presented clear or suggestive anxiety symptoms (respectively 21,6% and 25,7%). Stress and anxiety rates were much higher than those expected in infertile population. Increased stress was observed in women above 35 years and those stopped 'in cycle' or during pre-treatment for in-vitro fertilization or frozen embryo transfer. Patient with history of depression or anxiety had a higher prevalence of perceived stress (p= 0,0006). Postponement was perceived as 'unbearable' for women experiencing stress (p=0,0032). After the first wave of pandemic, pregnancy desire remained the same and 84,3% of women wanted to resume fertility care as soon as possible. CONCLUSIONS: Stopping fertility care during the COVID-19 pandemic had a significant psychological impact on women with an increase of stress, and anxiety. Psychological counseling should always be offered especially during this difficult period. IMPACT STATEMENT: This is the first psychological study using systematic scale.

Effectiveness and acceptability of "at home" versus "at hospital" early medical abortion - A lesson from the COVID-19 pandemic: A retrospective cohort study.

BACKGROUND: Since the lockdown caused by the COVID-19 pandemic, restrictions on hospitals' activity forced healthcare practitioners to innovate in order to provide continuity of care to patients. The aim of this study was to evaluate the efficiency of a newly established protocol for medical abortion and to measure the level of satisfaction of the patients who experienced abortion at home. METHODS: This retrospective study compared all the patients who had an early medical abortion at up to 9 weeks of gestation during the two drastically different periods between December 2018 and March 2021 ("hospital" and "home" groups). We evaluated the expulsion of the gestational sac as a primary outcome. The rates of infection, hemorrhage, retained trophoblastic material and need for surgical management were also assessed. A survey was also used to measure the satisfaction and acceptability of the method. RESULTS: The rate of expulsion of pregnancy was not significantly different between the two groups: 92.9% in hospital versus 99% at home. Early retained trophoblastic material and surgical interventions were higher in the hospital group. No significant difference was observed for the remaining outcomes. Moreover, the level of acceptability was similar in both groups, though patients felt safer in the "hospital" group. CONCLUSION: Switching an early medical abortion protocol from expulsion of pregnancy in hospital to expulsion of pregnancy at home is effective and acceptable to women, and may be associated with decreased rate of retained trophoblastic material. Further larger studies are needed to test the long-term result of this protocol.

Severe Acute Respiratory Syndrome Coronavirus 2 and Pregnancy Outcomes According to Gestational Age at Time of Infection.

We conducted an international multicenter retrospective cohort study, PregOuTCOV, to examine the effect of gestational age at time of infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on obstetric and neonatal outcomes. We included all singleton pregnancies with a live fetus at 10 weeks' gestation in which pregnancy outcomes were known. The exposed group consisted of patients infected with SARS-CoV-2, whereas the unexposed group consisted of all remaining patients during the same period. Primary outcomes were defined as composite adverse obstetric outcomes and composite adverse neonatal outcomes. Of 10,925 pregnant women, 393 (3.60%) were infected with SARS-CoV-2 (exposed group). After matching for possible confounders, we identified statistically significant increases in the exposed group of composite adverse obstetric outcomes at >20 weeks' gestation and of composite adverse neonatal outcomes at >26 weeks' gestation (p<0.001). Vaccination programs should target women early in pregnancy or before conception, if possible.

Evaluation of High-Throughput SARS-CoV-2 Serological Assays in a Longitudinal Cohort of Patients with Mild COVID-19: Clinical Sensitivity, Specificity, and Association with Virus Neutralization Test

BACKGROUND: The association between SARS-CoV-2 commercial serological assays and virus neutralization test (VNT) has been poorly explored in mild patients with COVID-19. METHODS: 439 serum specimens were longitudinally collected from 76 healthcare workers with RT-PCR-confirmed COVID-19. The clinical sensitivity (determined weekly) of 9 commercial serological assays were evaluated. Clinical specificity was assessed using 69 pre-pandemic sera. Correlation, agreement, and concordance with the VNT were also assessed on a subset of 170 samples. Area under the ROC curve (AUC) was estimated at 2 neutralizing antibody titers. RESULTS: The Wantai Total Ab assay targeting the receptor binding domain (RBD) within the S protein presented the best sensitivity at different times during the course of disease. The clinical specificity was greater than 95% for all tests except for the Euroimmun IgA assay. The overall agreement with the presence of neutralizing antibodies ranged from 62.2% (95%CI;56.0-68.1) for bioMerieux IgM to 91.2% (87.0-94.2) for Siemens. The lowest negative percent agreement (NPA) was found with the Wantai Total Ab assay (NPA 33% (21.1-48.3)). The NPA for other total Ab or IgG assays targeting the S or the RBD was 80.7% (66.7-89.7), 90.3% (78.1-96.1), and 96.8% (86.8-99.3) for Siemens, bioMerieux IgG, and DiaSorin, respectively. None of the commercial assays have sufficient performance to detect a neutralizing titer of 80 (AUC < 0.76). CONCLUSIONS: Although some assays show a better agreement with VNT than others, the present findings emphasize that commercialized serological tests, including those targeting the RBD, cannot substitute a VNT for the assessment of functional antibody response.

Covid-19 and blood groups: ABO antibody levels may also matter.

BACKGROUND: Susceptibility to Covid-19 has been found to be associated with the ABO blood group, with O type individuals being at a lower risk. However, the underlying mechanism has not been elucidated. Here, we aimed to test the hypothesis that Covid-19 patients might have lower levels of ABO antibodies than non-infected individuals as they could offer some degree of protection. METHODS: After showing that the viral spike protein harbors the ABO glycan epitopes when produced by cells expressing the relevant glycosyltransferases, like upper respiratory tract epithelial cells, we enrolled 290 patients with Covid-19 and 276 asymptomatic controls to compare their levels of natural ABO blood group antibodies. RESULTS: We found significantly lower IgM anti-A + anti-B agglutination scores in blood group O patients (76.93 vs 88.29, P-value = 0.034) and lower levels of anti-B (24.93 vs 30.40, P-value = 0.028) and anti-A antibodies (28.56 vs 36.50, P-value = 0.048) in blood group A and blood group B patients, respectively, compared to controls. CONCLUSION: In this study, we showed that ABO antibody levels are significantly lower in Covid-19 patients compared to controls. These findings could indicate that patients with low levels of ABO antibodies are at higher risk of being infected.
