This study was designed to investigate patterns and risk factors for substance use among obstetrical patients who gave birth during the early period of the pandemic, and their partners. Cross-sectional survey of obstetrical patients between March 17th and June 16th, 2020, at The Ottawa Hospital, Ottawa, Canada. Substance use was a composite measure of any alcohol, tobacco, or cannabis use since COVID-19 began. Four outcomes included: any participant substance use or increase in substance use, any partner substance use or increase in substance use. Adjusted risk ratios (ARR) and 95% confidence intervals (CI) are presented. Of 216 participants, 113 (52.3%) and 15 (6.9%) obstetrical patients reported substance use and increased use, respectively. Those born in Canada (ARR: 2.03; 95% CI: 1.27–3.23) and those with lower household income (ARR: 1.38; 95% CI: 1.04–1.85) had higher risk of substance use. Those with postpartum depression (ARR: 5.78; 95%CI: 2.22–15.05) had the highest risk of increased substance use. Families affected by school/daycare closure reported a higher risk of increased partner substance use (ARR: 2.46; 95% CI:1.38–4.39). This study found that risk factors for substance use included demographics (i.e., being born in Canada, income), mental health (postpartum depression), and school/childcare closures.

Low-dose aspirin is recommended for pregnant individuals at high-risk of developing preeclampsia, but less is known about those that develop preeclampsia even while using prophylactic aspirin for preeclampsia prevention as the best course of treatment. The objective of this study is to investigate the risk factors with the highest risk of developing preeclampsia among pregnant individuals already using aspirin from high-risk obstetrical centers across five countries. This is a secondary analysis of pregnant individuals from the Folic Acid Clinical Trial (FACT) who were using prophylactic aspirin before 16 weeks gestation. The FACT randomized control trial took place in 70 high risk obstetrical centers in Canada, United Kingdom, Australia, Jamaica, and Argentina between 2011–2015. Participants were included if they had any of the risk factors for preeclampsia: diabetes, chronic hypertension, twin pregnancy, history of preeclampsia, and/or obesity (Body Mass Index ≥35). The outcomes of interest were preeclampsia and preterm preeclampsia (<37 weeks). Log binomial regressions assessed factors significantly associated with any preeclampsia or preterm-preeclampsia (<37 weeks) using adjusted risk ratios (ARR) and 95% confidence intervals (CI). There were 2296 pregnant individuals with complete information on aspirin included in this study. At baseline, all patients were at high risk of preeclampsia and were eligible for aspirin prophylaxis, however, only 660 (28.7%) were taking aspirin. Among the 660 pregnant individuals taking aspirin, 132 (20%) developed preeclampsia and 60 (9.09%) preterm preeclampsia. Among pregnant individuals using aspirin, the risks of preeclampsia were highest for twins (ARR:2.62, 95% CI: 1.68–4.11), history of preeclampsia (ARR: 2.42, 95% CI: 1.74–3.38), and hypertension (ARR:1.92, 95% CI: 1.37–2.69). Similar trends were found for preterm-preeclampsia for twins (ARR:4.10, 95% CI:2.15–7.82), history of preeclampsia (ARR:2.75, 95% CI:1.62–4.67), and hypertension (ARR:2.18, 95% CI:1.28–3.72). No significant differences were found for obesity or diabetes. These findings suggest that individuals with twin pregnancies, a history of preeclampsia, or hypertension may not benefit from aspirin to the same extent as those with other complications such as obesity or diabetes. Careful clinical monitoring for these risks factors is recommended and future research into the effectiveness in these populations would increase our understanding of the current best practice of prophylactic aspirin use to prevent preeclampsia.

Background: Education is considered one of the most robust determinants of health. However, it is unclear whether maternal education and paternal education have differential impacts on perinatal health outcomes. We assess maternal and paternal education differences and their association with adverse birth outcomes in a large birth cohort from Ontario, Canada. Methods: The OaK Birth Cohort recruited patients from Ontario, Canada, between October 2002 and April 2009. We recruited mothers were recruited between 12 and 20 weeks’ gestation and collected both mother and infant data. The final sample size of the cohort was 8,085 participants. We use logistic regression to model the probability of preterm birth (less than 34 and 37 weeks’ gestation), small-for-gestational-age (SGA), or stillbirth as a function of maternal and paternal educational attainment. We adjust for household-level income, maternal and paternal race and ethnicity, and compare the strength of the association between maternal and paternal education on outcomes using Wald tests. Results: 7,928 mother-father-offspring triads were available for the current analysis. 75% of mothers and fathers had college or university level education, and 8.7% of mothers experienced preterm delivery. Compared to mothers with college or university education, mothers with a high school education had an odds ratio of 1.37 (95% CI: 1.01–1.87) for SGA. Paternal education was not associated with infant outcomes. Comparing the odds ratios for maternal education and paternal education showed a stronger association than paternal education at the high school level for SGA birth (difference in odds ratio: 1.95, 95% CI: 1.13–3.36, p = .016) among women at least 25 years old. Conclusion: Maternal education was associated with SGA, and this effect was more robust than paternal education, but both associations were weaker than previously reported. [ABSTRACT FROM AUTHOR]

To determine the efficacy of high-dose folic acid for the prevention of preeclampsia in twin pregnancies. Secondary analysis of a randomized controlled trial in 70 obstetrical sites in Argentina, Australia, Canada, Jamaica, and the UK between 2011 and 2015. Eligible women pregnant with twins who were aged 18 y or older and between 8 and 16 completed weeks' gestation were randomized between to receive daily high-dose folic acid (4.0–5.1 mg) or placebo. The primary outcome was preeclampsia, presenting as hypertension after 20 weeks' gestation with significant proteinuria. Secondary outcomes included severe preeclampsia, preterm birth, and adverse fetal and neonatal outcomes. Of 2464 participants randomized between 18 April 2011 and 14 December 2015, 462 (18.8%) had a confirmed twin pregnancy. Thirty-four of these participants withdrew consent or did not have primary outcome data available, and 428 women were analyzed. The rate of preeclampsia was significantly higher in the folic acid group compared to the placebo group in crude analyses (17.2 versus 9.9%; relative risk 1.75 [95% CI 1.06–2.88], p =.029). Multivariable analyses attenuated this effect, rendering it not statistically significant (RR 1.58 [95% CI 0.95–2.63], p =.079). High-dose folic acid supplementation was not significantly associated with preeclampsia in a subgroup of twin pregnancies. Although a suggested elevated risk cannot be confirmed, these results may help to gain novel insights in the etiology of preeclampsia, which continues to be poorly understood.

The tick-borne condition Lyme borreliosis, commonly known as Lyme Disease, is an emerging problem in the U.K. Thus media coverage highlighting clinical features and measures to prevent tick bites is welcome. How well does the news media provide this information? Here, reports from the British Public Service Broadcaster, the BBC, were examined. BBC coverage of Lyme Disease was classed depending on media type as 'television', 'radio' or 'web page'. Keywords related to symptoms and prevention techniques were recorded. Images of ticks or the characteristic EM rashes were also noted. More reports occurred in the spring and summer months than autumn and winter (Q2, 31.7%: Q3, 29.1%). Early diagnostic features such as a 'rash' (53.3%) and reference to tick bites (68.9%) were frequently mentioned. Other symptoms were well covered; including fever or 'flu-like' symptoms (43.6%), malaise (35.9%) and joint pain (43.6%). Less often mentioned were focal symptoms; including arthritis (8.7%) or facial palsy (6.7%). Prevention techniques were mentioned in 32% of all media reports, with tick removal (26.2%) and body checking (20.3%) being most often mentioned. Tick images were frequently provided (40.7%), but those of EM rashes less often (16.5%). Overall, coverage of early symptoms was high. However, symptoms indicative of later infection were less well covered. Increased use of EM images, and more appropriate tick images, could aid Lyme Disease identification amongst the general public.

Abstract Objective Results Conclusion Benign spinal intradural tumors are rare entities and there have been relatively few case series describing the epidemiology and characteristics of these tumors. Here, we evaluate the presentation, demographics, pathology and outcomes associated with the surgical management of spinal meningioma in our unit over a 6-year period.A total of 68 cases presented to the operating surgeon during a 6-year period. Of these, over 80% (n = 55) were in females. Seventy-nine percent of the meningiomas were observed in the thoracic region (n = 54). Weakness and gait disturbance were the most common presenting complaints. Surgery significantly improved both motor outcome (p < 0.001) and health related qualities of life (SF36, p < 0.01).Seventeen percent of spinal meningioma cases (n = 12) had a preceding cancer diagnosis. Of these 75% (n = 9/12) were attributable to breast cancer. Overall, breast cancer preceded a diagnosis of a spinal meningioma in 16.4% of female cases (9/55). This is higher than expected number of breast cancer based on UK population and those reported in literature for breast cancer and intracranial meningioma.Spinal meningioma is disproportionately over-represented in females. Patients present with neurological deficits and surgery improved both neurology and patient reported quality of life. Relative to the known UK prevalence of breast cancer, there is a significantly higher than expected association between spinal meningioma and a preceding history of breast cancer.
