An electrophysiological substrate of COVID-19.

SARS-CoV-2 infection is associated with an increased risk of late cardiovascular (CV) outcomes. However, more data is needed to describe the electrophysiologic (EP) manifestation of post-acute CV sequelae of COVID-19. We compared two cohorts of adult patients with SARS-CoV-2 polymerase chain reaction (PCR) test and an electrocardiogram (ECG) performed between March 1, 2020, and September 13, 2020, in a retrospective double-cohort study, "Cardiovascular Risk Stratification in Covid-19" (CaVaR-Co19; NCT04555187). Patients with positive PCR comprised a COVID-19(+) cohort (n = 41; 61% women; 80% symptomatic), whereas patients with negative tests formed the COVID-19(-) cohort (n = 155; 56% women). In longitudinal analysis, comparing 3 ECGs recorded before, during, and on average 40 days after index COVID-19 episode, after adjustment for demographic and socioeconomic characteristics, baseline CV risk factors and comorbidities, use of prescription medications (including QT-prolonging drugs) before and during index COVID-19 episode, and the longitudinal changes in RR' intervals, heart rhythm, and ventricular conduction type, only in the COVID-19(+) cohort QTc increased by +30.2(95% confidence interval [CI] 0.1-60.3) ms and the spatial ventricular gradient (SVG) elevation increased by +13.5(95%CI 1.2-25.9)°. In contrast, much smaller, statistically nonsignificant changes were observed in the COVID-19(-) cohort. In conclusion, post-acute CV sequelae of SARS-CoV-2 infection manifested on ECG by QTc prolongation and rotation of the SVG vector upward.

Women's experience with group prenatal care in a rural community in northern Nigeria.

OBJECTIVE: To assess women's experience of group prenatal care in a rural Nigerian community. METHODS: In an observational study, consenting pregnant women were enrolled in a group prenatal care program based on the CenteringPregnancy model from July 1, 2010, to June 30, 2011, in Tsibiri, Nigeria. Women were interviewed before joining the group and postnatally. A predesigned pro forma was used to assess group behavior during sessions. Descriptive and inferential statistics were applied to data. RESULTS: In total, 161 women enrolled, and 54 of 72 scheduled prenatal sessions took place. The average number of visits was three per woman, with good group interaction and cohesion. Mothers who could mention at least five out of eight danger signs of pregnancy increased from 1.4% (2) to 13.3% (14) (P<0.001, 95% CI 4.28-19.52), while mean knowledge score for danger signs increased from 31% to 47.8% (P<0.001, 95% CI 0.86-2.16). Commitment to birth preparedness plans was impressive. The mothers enjoyed the group sessions and shared the lessons they learned with others. CONCLUSION: Group prenatal care was feasible and acceptable to women in the present study setting. Comparative trials would be helpful to demonstrate the benefits of the tested model in low-income settings.

A cross-sectional study of traditional practices affecting maternal and newborn health in rural Nigeria.

INTRODUCTION: Certain traditional practices which have negative effects on maternal and child health continue to be practiced in sub-Saharan African countries. A survey was carried out in a rural village in Nigeria to understand the scale and range of these practices. METHODS: This was a cross-sectional study in which trained interviewers administered pre-tested questionnaires on child-bearing women using questionnaires embedded on android devices. RESULTS: The median age of marriage and pregnancy were 15 and 16 years respectively. Home births were high (90.4%) while non-skilled birth attendant was 87.4%. The community had a son preference index ratio of 1:4.1. Up to 81.5% of mothers responded that one form of unhygienic traditional procedure or the other was performed on their children. Time to initiation of breast feeding was in hours in the majority (76.3%) of mothers, with a high rate of use of prelacteal feeds (85.2%). Being an adolescent mother (AOR 0.403, 95%CI 0.203, 0,797) and utilizing a skilled provider at birth (AOR 0.245, 95%CI 0.088, 0.683) were associated with less likelihood of having an unhygienic procedure performed on children. CONCLUSION: The findings of our study suggest that traditional practices which could have negative effects on maternal and child health are still ongoing in the study community. Child protection laws and safeguarding principles could help to reduce these practices and would need to be developed and implemented in these settings where these practices are still prevalent.
