Hemophagocytic Lymphohistiocytosis Associated With T-cell Lymphoma in Pregnancy: Diagnostic Conundrum Unveiled.

Hemophagocytic lymphohistiocytosis (HLH) during pregnancy is a rare and often misdiagnosed disease. The clinical manifestations are non-specific, contributing to a high maternal mortality rate. This case report details the presentation of a 31-year-old pregnant woman with high-grade fever initially treated as an infection-related condition. The diagnostic challenge arose from the rarity of HLH, its variable clinical presentation, and the lack of specificity in clinical and laboratory findings. Despite numerous tests and escalation of therapies, the patient, unfortunately, succumbed to HLH associated with T-cell lymphoma. This case report aims to raise awareness of HLH, emphasizing its challenging definition. Malignancy-associated HLH is not uncommon, and early identification and treatment are paramount to prevent progressive tissue damage, organ failure, and mortality. The atypical presentation of HLH as a clinical manifestation of T-cell lymphoma underscores the need for vigilance in diagnosing this potentially fatal syndrome.

Pregnancy Outcomes Among Women With Sickle Cell Disease in Bahrain: A Case-Control Study.

Objectives The study sought to evaluate and compare the maternal and fetal outcomes of pregnancy in women with sickle cell disease (SCD) versus healthy pregnant women in Bahrain. The objective was to update the available data in order to come up with a strategy to implement a multidisciplinary management program, which will enhance pregnancy outcomes for the SCD patient population. Materials and methods This retrospective case-control study was conducted in the Obstetrics and Gynecology Department at Salmaniya Medical Complex (SMC) in Bahrain. The study group consisted of all pregnant women with homozygous SCD (HbSS) who delivered at SMC between January 1, 2019, and December 31, 2021. The control group comprised pregnant women who delivered at SMC during the same period but did not have SCD or trait. Data for the study were collected from the healthcare system records at SMC, specifically the I-Seha electronic medical record system and the labor room registry book. A thorough review and analysis of the data were conducted, encompassing 217 cases of SCD and 200 controls. The variables examined included nationality, age, gravidity, parity, gestational age, reason for admission, antenatal/postnatal complications (such as urinary tract infection, pneumonia, acute chest syndrome, thromboembolism, premature rupture of membranes, hypertension, pre-eclampsia, and intrauterine growth restriction), type of delivery, birth weight, newborn outcome, and postnatal complications. Results Pregnant women with SCD experienced significantly higher rates of antenatal hospitalization compared to controls - 69.6% were admitted at least twice versus only 16.5%. Vaso-occlusive crises were the primary reason for admission in over half of SCD patients, with 22.6% having one episode, 11.1% having two, and 20.3% having more than two during pregnancy. Low hemoglobin levels also necessitated admission in 11.1% of SCD women, while no controls required hospitalization for this. The burden of maternal morbidity was substantially greater in the SCD group, with only 20.3% free of complications versus 94% in controls. SCD women had elevated rates of blood transfusions, acute chest syndrome, and urinary tract infections. Adverse pregnancy outcomes were also more common, including higher risks of preterm birth, low birth weight, and intrauterine growth restriction. Despite these increased maternal and fetal risks, there was no significant difference in the incidence of hypertensive disorders between groups. Interestingly, our data showed a significantly lower incidence of gestational diabetes in the SCD group compared to controls (8.3% vs. 18%). Tragically, one maternal death occurred in the SCD group, although the overall maternal mortality did not differ significantly. Conclusion SCD poses substantial risks for mother and fetus. Careful monitoring with a multidisciplinary team and patient education are crucial. Early detection can reduce morbidity and mortality. Further research is needed on interventions to improve outcomes.

Cardiac implantable electronic devices in pregnancy: A position statement.

The aim of this document is to provide guidance for the management of women and birthing people with a permanent pacemaker (PPM) or implantable cardioverter defibrillator (ICD). Cardiac devices are becoming more common in obstetric practice and a reference document for contemporary evidence-based practice is required. Where evidence is limited, expert consensus has established recommendations. The purpose is to improve safety and reduce the risk of adverse events relating to implanted cardiac devices during pregnancy, birth and the postnatal period.

Clinical Analysis of Postpartum Preeclampsia After an Uncomplicated Pregnancy.

Preeclampsia is a rare complication of pregnancy and can cause maternal death. This case report serves to increase awareness of the range and severity of symptoms in postpartum preeclampsia and highlights a stepwise approach to provide prompt management. The cause of preeclampsia is not fully understood but is correlated with many placental and maternal factors. Preeclampsia typically resolves with delivery, and it is uncommon to have symptoms in the postpartum period. Due to the rarity of the disease, it is not typically at the top of a differential list for postpartum women. A 35-year-old first-time mother presents with shortness of breath, tightness in her chest, and mild pulmonary edema. A series of chest X-rays, computed tomographic angiogram of the chest, and serial labs reveal she has postpartum preeclampsia. Many pre-eclamptic symptoms are common to a variety of conditions leading to an extensive list of differential diagnoses. Used in a stepwise fashion, clinical analysis allows physicians to accurately diagnose postpartum preeclampsia and provide lifesaving treatment for these mothers. This study highlights the need for vigilance in symptom analysis and diagnostic testing.

Determination of the Contributing Factors and HbA1c Cutoff Leading to Glucose Tolerance Abnormalities Following Gestational Diabetes.

The prevalence of gestational diabetes mellitus (GDM) has been steadily increasing over the past years. It is a major risk factor for glucose intolerance and type 2 DM (T2DM). The American Diabetes Association recommends that women whose pregnancy was complicated by GDM be screened for persistent glucose abnormalities at six to 12 weeks postpartum with either a fasting plasma glucose test alone or with a fasting 75-g, two-hour oral glucose tolerance test. This study aimed to identify the main predictive factors of glucose tolerance disorders in early postpartum women with a recent history of GDM. In this retrospective descriptive study, we identified 400 women who met the eligibility criteria for the study. The mean age was 34.54 ± 5.51 years. A total of 70% had a family history of DM, 16% had a personal history of GDM, and 23% had fetal macrosomia in previous pregnancies. The overall incidence of postpartum carbohydrate tolerance disorders was 36.4%, including 12% prediabetes and 24.4% DM. The prevalence of prediabetes and T2DM after delivery was higher with older maternal age, multigravidity, a higher BMI, a history of GDM, and fetal macrosomia in previous pregnancies. Furthermore, the persistence of this impaired glucose tolerance in postpartum was associated with a higher term of diagnosis, a higher glycated hemoglobin (HbA1c) percentage (the discriminant cutoff value with the best sensitivity/specificity ratio was 5.25%), the use of insulin therapy, cesarean section delivery, and fetal macrosomia. After adjusting for confounders, only prior GDM, a higher HbA1c level, macrosomia, and gestational term were found to significantly affect postpartum glucose tolerance. Although postpartum screening for T2DM is recommended for all women with GDM, a significant number of patients fail it. A better knowledge of predictive factors for this outcome is therefore needed for a more effective and targeted medical intervention.

Use of opioids among pregnant women 1997-2016: A Danish drug utilization study.

OBJECTIVE: Use of opioids in pregnancy is of concern yet little is known on opioid prescription patterns in Denmark. The aim of this drug utilization study was to describe prescription patterns for opioids during pregnancy in Denmark from 1997 to 2016. STUDY DESIGN: Using the nationwide health care registers, we obtained information on all women with a registered pregnancy in the period 1 January 1997 to 31 December 2016. Opioids were grouped in four: opioids (N02A except codeines), opioid dependency medications (N07BC), cough medications (R05DA except codeines), and codeines (N02AJ06, N02AJ07, N02BA75, and R05DA04). We used logistic regression analyses to identify factors associated with opioid use in pregnancy and cumulative oral morphine equivalent (OMEQ) to estimate volume of use in pregnancy. RESULTS: Prescription patterns were similar for women with live births, non-live births, and terminations. Total use of opioids among women with live born deliveries remained stable at 19.8 per 1000 pregnancies from 1997 to 2016. Codeine use declined from 2008 onwards, while use of other opioids increased from 2007 onwards. This was dominated by a threefold increase in tramadol use (2.0-7.6 per 1000 pregnancies with live births). Codeine was the most used opioid, followed by tramadol and codeine combined with paracetamol. The number of women, who used opioids before pregnancy and continued into their pregnancy, was reduced as the pregnancy progressed. The cumulative oral morphine equivalent during pregnancy was stable until 2007, after which, use prior to pregnancy and during the first two trimesters increased. The odds ratios for opioid use were higher in pregnancies of women of lower socioeconomic status or older age. For live births, odds ratios for opioid use in pregnancy were higher among women with obesity or smoking. CONCLUSIONS: Overall use of opioids was stable from 2007 to 2016. This covers a decline in the use of codeine, but a 3-fold increase in tramadol. The number of pregnant women who continued use throughout pregnancy decreased, while OMEQ among persistent users increased. The real-world data suggest an unmet need of specific focus in local Danish Outpatient Clinics and Multidisciplinary Pain Centers both pre-conceptionally and during pregnancy.

Skin Manifestations of Neuromyelitis Optica Spectrum Disorder With Secondary Systemic Lupus Erythematosus During Pregnancy: A Three-Year Follow-Up.

Neuromyelitis optica spectrum disorder (NMOSD) is a disease of the central nervous system and the optic nerves that disproportionately affects women and occasionally coexists with other autoimmune diseases. NMOSD manifesting as skin lesions is a rare phenomenon. Furthermore, these skin lesions in the setting of NMOSD during pregnancy have not been described. We report the case of a 31-year-old woman from sub-Saharan Africa who presented with initial recurrent skin lesions followed by paraparesis during her second trimester of pregnancy. Her next pregnancy was associated with sudden vision loss. She had positive serology for aquaporin-4 antibodies and subsequently developed a positive dsDNA antibody two years after the initial NMOSD diagnosis. Her skin lesions and symptoms improved following the administration of azathioprine. This case highlights the impact of pregnancy on NMOSD and the significance of a heightened level of suspicion for NMOSD in patients who exhibit recurring skin lesions preceding paraparesis events.

Early HELLP Syndrome or Catastrophic Antiphospholipid Syndrome? A Diagnostic Dilemma.

Hypertensive disorders of pregnancy typically occur in the third trimester, with earlier presentations associated with underlying disorders such as antiphospholipid syndrome (APLS). We describe a case of a young primigravida presenting at 15 weeks 6 days gestation with epigastric pain, vomiting, new-onset severe-range hypertension, and subsequent development of anemia, thrombocytopenia, and transaminitis. Antiphospholipid antibodies (aPL) were triple-positive and imaging was negative for thrombosis. She was treated with aspirin, therapeutic anticoagulation, and ultimately dilatation and evacuation with initial postoperative improvement. Her symptoms returned postoperative day 3 and resolved following re-initiation of therapeutic anticoagulation. The differential diagnosis for hypertensive disorders of pregnancy is wide, particularly in second-trimester gestation, and includes catastrophic antiphospholipid syndrome (CAPS), lupus flare, microangiopathic anemias, and acute fatty liver of pregnancy. This case was an atypical presentation not clearly explained by any of the above diagnoses and required a multidisciplinary approach. Obstetric patients with high-risk aPL must be meticulously investigated with a broad differential to guide diagnosis and treatment.

Trends in Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection and vaccine antibody prevalence in a multi-ethnic inner-city antenatal population: A cross-sectional surveillance study.

OBJECTIVE: To determine severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) seroprevalence in pregnancy in an inner-city setting and assess associations with demographic factors and vaccination timing. DESIGN: Repeated cross-sectional surveillance study. SETTING: London maternity centre. SAMPLE: A total of 906 pregnant women attending nuchal scans, July 2020-January 2022. METHODS: Blood samples were tested for IgG antibodies against SARS-CoV-2 nucleocapsid (N) and spike (S) proteins. Self-reported vaccination status and coronavirus disease 2019 (COVID-19) infection were recorded. Multivariable regression models determined demographic factors associated with seroprevalence and antibody titres. MAIN OUTCOME MEASURES: Immunoglobulin G N- and S-protein antibody titres. RESULTS: Of the 960 women, 196 (20.4%) were SARS-CoV-2 seropositive from previous infection. Of these, 70 (35.7%) self-reported previous infection. Among unvaccinated women, women of black ethnic backgrounds were most likely to be SARS-CoV-2 seropositive (versus white adjusted risk ratio [aRR] 1.88, 95% CI 1.35-2.61, p < 0.001). Women from black and mixed ethnic backgrounds were least likely to have a history of vaccination with seropositivity to S-protein (versus white aRR 0.58, 95% CI 0.40-0.84, p = 0.004; aRR 0.56, 95% CI 0.34-0.92, p = 0.021, respectively). Double vaccinated, previously infected women had higher IgG S-protein antibody titres than unvaccinated, previously infected women (mean difference 4.76 fold-change, 95% CI 2.65-6.86, p < 0.001). Vaccination timing before versus during pregnancy did not affect IgG S-antibody titres (mean difference -0.28 fold-change, 95% CI -2.61 to 2.04, p = 0.785). CONCLUSIONS: This cross-sectional study demonstrates high rates of asymptomatic SARS-CoV-2 infection with women of black ethnic backgrounds having higher infection risk and lower vaccine uptake. SARS-CoV-2 antibody titres were highest among double-vaccinated, infected women.

Effectiveness of brief alcohol interventions for pregnant women: a systematic literature review and meta-analysis.

BACKGROUND: Prenatal alcohol exposure (PAE) can result in a range of adverse neonatal outcomes, including Fetal Alcohol Spectrum Disorder (FASD). This systematic review and meta-analysis sought to investigate the effectiveness of brief interventions (BIs) in eliminating or reducing 1) alcohol consumption during pregnancy; and 2) PAE-related adverse neonatal outcomes; and 3) cost-effectiveness of BIs. METHOD: We conducted a systematic literature search for original controlled studies (randomized control trials (RCTs); quasi-experimental) in any setting, published from 1987 to 2021. The comparison group was no/minimal intervention, where a measure of alcohol consumption was reported. Studies were critically appraised using the Centre for Evidence-based Medicine Oxford critical appraisal tool for RCTs (1). The certainty in the evidence for each outcome was assessed using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) (2). Meta-analysis of continuous and binary estimates of effect-size for similar outcome measures for BIs versus control groups were pooled and reported as mean difference (MD) Hedges' g and odds ratios (ORs), respectively. RESULTS: In total, 26 studies, all from high income countries, met inclusion criteria. Alcohol abstinence outcome available in 12 studies (n = 2620) found modest effects in favor of BIs conditions by increasing the odds of abstinence by 56% (OR = 1.56, 95% confidence interval (CI) = 1.15-2.13, I2 = 46.75%; p = 0.04). BIs effects for reduction in mean drinks/week (Cohen's d = - 0.21, 95%CI = - 0.78 to 0.36; p = 0.08) and AUDIT scores (g = 0.10, 95%CI = - 0.06 to 0.26; p = 0.17) were not statistically significant. Among seven studies (n = 740) reporting neonatal outcomes, BI receipt was associated with a modest and significant reduction in preterm birth (OR = 0.67, 95% CI = 0.46-0.98, I2 = 0.00%; p = 0.58). No statistically significant differences were observed for mean birthweight or lower likelihood of low birth weight (LBW). Certainty in the evidence was rated as 'low'. No eligible studies were found on cost-effectiveness of BIs. CONCLUSION: BIs are moderately effective in increasing abstinence during pregnancy and preventing preterm birth. More studies on the effectiveness of BIs are needed from low- and middle-income countries, as well as with younger mothers and with a broader range of ethnic groups.

Risk for adverse maternal outcomes among women with chronic hypertension.

OBJECTIVE: To determine whether longitudinal health data accounts for end-organ injury or death in the setting of chronic hypertension. DESIGN: Cohort of 64 799 deliveries to 61 854 women. SETTING: US claims data for the preiod 2008-2019. POPULATION: Women with a delivery hospitalisation and chronic hypertension. METHODS: Risk for a composite of acute end-organ injury or death during the delivery hospitalisation and 30 days postpartum was analysed. Adjusted logistic regression models were derived with discrimination for each model estimated by the C-statistic. Poisson regression was used to estimate adjusted risk ratios. Starting with models using data from pregnancy, further adjustment was performed accounting for healthcare use in the year prior to pregnancy, including hospitalisations, emergency department encounters, prescription medications and pre-pregnancy diagnoses. MAIN OUTCOME MEASURES: Acute end-organ injury or death. RESULTS: The composite outcome occurred among 5.7% of 64 799 deliveries. For patients with commercial insurance, filling non-hypertensive medications from ≥11 different classes, compared with none (adjusted risk ratio, aRR 4.07, 95% CI 2.86-5.79), three or more hospitalisations before pregnancy, compared with none (aRR 4.75, 95% CI 3.46-6.52), and chronic kidney disease diagnosed in the year before pregnancy (aRR 2.35, 95% CI 1.88, 2.94) were associated with increased risk. For pregnancies covered by commercial insurance, the C-statistic increased from 0.615 (95% CI 0.599-0.630) in the model with pregnancy data only to 0.796 (95% CI 0.783-0.808) for the model additionally including healthcare use in the year before pregnancy. Findings with Medicaid were similar. CONCLUSIONS: Prepregnancy care use predicted adverse maternal outcomes. These data may be important in risk stratification.

Testing equivalence of two doses of intravenous iron to treat iron deficiency in pregnancy: A randomised controlled trial.

OBJECTIVE: To test the equivalence of two doses of intravenous iron (ferric carboxymaltose) in pregnancy. DESIGN: Parallel, two-arm equivalence randomised controlled trial with an equivalence margin of 5%. SETTING: Single centre in Australia. POPULATION: 278 pregnant women with iron deficiency. METHODS: Participants received either 500 mg (n = 152) or 1000 mg (n = 126) of intravenous ferric carboxymaltose in the second or third trimester. MAIN OUTCOME MEASURES: The proportion of participants requiring additional intravenous iron (500 mg) to achieve and maintain ferritin >30 microg/L (diagnostic threshold for iron deficiency) at 4 weeks post-infusion, and at 6 weeks, and 3-, 6- and 12-months postpartum. Secondary endpoints included repeat infusion rate, iron status, birth and safety outcomes. RESULTS: The two doses were not equivalent within a 5% margin at any time point. At 4 weeks post infusion, 26/73 (36%) participants required a repeat infusion in the 500-mg group compared with 5/67 (8%) in the 1000-mg group: difference in proportions, 0.283 (95% confidence interval [CI] 0.177-0.389). Overall, participants in the 500-mg arm received twice the repeat infusion rate (0.81 [SD = 0.824] versus 0.40 [SD = 0.69], rate ratio 2.05, 95% CI 1.45-2.91). CONCLUSIONS: Administration of 1000 mg ferric carboxymaltose in pregnancy maintains iron stores and reduces the need for repeat infusions. A 500- mg dose requires ongoing monitoring to ensure adequate iron stores are reached and sustained.

Eclampsia in Italy: A prospective population-based study (2017-2020).

OBJECTIVE: To estimate the incidence, and to investigate risk factors, management, and perinatal outcomes of eclampsia in Italy. STUDY DESIGN: This is a prospective population-based cohort study enrolling all women admitted for eclampsia between November 2017 and March 2020. Incident cases were reported using electronic and anonymous data collection forms. MAIN OUTCOME MEASURES: Incidence, risk factors, maternal and perinatal morbidity, and mortality. RESULTS: 109 cases were included for an estimated incidence rate of 1.5 (95 % CI 1.2-1.8) per 10.000 births. Risk of developing eclampsia was associated with multiple pregnancies (RR = 4.51; p < 0.001) and with pregnancies achieved with assisted reproductive technologies (RR = 3.03; p < 0.001). Magnesium sulfate was used as prophylaxis in almost 30 % of women with preeclampsia, and to treat an eclamptic fit in 89 % of women. The time interval between the first fit and delivery was 62 min for antepartum and 10 min for intrapartum cases. Around one third of women developed at least one other major complication and one mother died. Severe morbidity affected 13.3 % of the newborns. Two fetal and one neonatal death were reported. CONCLUSIONS: Our data revealed low incidence of eclampsia in Italy and prompt administration of antihypertensive drugs and magnesium sulfate to prevent eclampsia and to treat the recurrence of seizures. However, the rate of severe maternal complications is still high: increasing the time interval between fit and delivery seems to be crucial to achieve an effective stabilization of maternal conditions and reduce maternal major complications.

Fetal and maternal outcomes after maternal biologic use during conception and pregnancy: A systematic review and meta-analysis.

BACKGROUND: Biologic medications, specifically tumour necrosis factor-α (TNF-α) inhibitors, have become increasingly prevalent in the treatment of chronic inflammatory disease (CID) in pregnancy. OBJECTIVE: To determine pregnancy outcomes in women with CID exposed to biologics during pregnancy. SEARCH STRATEGY: PubMed and EMBASE databases were searched through January 1998-July 2021. SELECTION CRITERIA: Peer-reviewed, English-language cohort, case-control, cross-sectional studies, and case series that contained original data. DATA COLLECTION AND ANALYSIS: Two authors independently conducted data extraction. A meta-analysis of proportions using a random-effects model was used to pool outcomes. Linear regression analysis was used to compare the mean of proportions of outcomes across exposure groups using the 'treated' group as the reference category. All studies were evaluated using an appropriate quality assessment tool. The GRADE approach was used to assess the overall certainty of evidence. MAIN RESULTS: Thirty-five studies, describing 11 172 pregnancies, were eligible for inclusion. Analysis showed pooled proportions for congenital malformations as follows: treated 0.04 (95% CI 0.03-0.04; I2  = 77) versus disease-matched 0.04 (95% CI 0.03-0.05. I2  = 86; p = 0.238); preterm delivery treated 0.04 (95% CI 0.10-0.14; I2  = 88) versus disease-matched 0.10 (95% CI 0.09-0.12; I2  = 87; p = 0.250); severe neonatal infection: treated 0.05 (95% CI 0.03-0.07; I2  = 88) versus disease-matched 0.05 (95% CI 0.02-0.07; I2  = 94; p = 0.970); low birthweight: treated 0.10 (95% CI 0.07-0.12; I2  = 93) versus disease-matched 0.08 (95% CI 0.07-0.09; I2  = 0; p = 0.241); pooled miscarriage: treated 0.13 (95% CI 0.10-0.15; I2  = 77) versus disease-matched 0.08 (95% CI 0.04-0.11; I2  = 5; p = 0.078); pre-eclampsia; treated 0.01 (95% CI 0.01-0.02; I2  = 0) versus disease-matched 0.01 (95% CI 0.00-0.01; I2  = 0; p = 0.193). No statistical differences in proportions were observed. GRADE certainty of findings was low to very low. CONCLUSION: We demonstrated comparable pregnancy outcomes in pregnancies exposed to biologics, disease-matched controls and CID-free pregnancies using the GRADE approach.

A 21st Century Epidemy-Obesity: And Its Impact on Pregnancy Loss.

The prevalence of obesity among women of reproductive age is growing significantly over the last years. Being obese or having a high body mass index (BMI) contributes to many diseases and pregnancy complications. This is concerning as an obese woman is at increased risk for developing several complications during pregnancy and is at increased risk for pregnancy loss, stillbirth, and metabolic disorders of a live-born child in his future. The pregnant woman's body mass index has to be monitored well during the whole pregnancy, and their diet should also be monitored to avoid future complications. Better results can be achieved if every woman would watch their weight before being pregnant for better outcomes in their future pregnancies. This review article aimed to determine the relationship between being obese or having a high BMI and pregnancy loss. Additionally, we tried to find the mechanism that is involved in pregnancy loss in obese women.

Maternal alcohol use, adverse neonatal outcomes and pregnancy complications in British Columbia, Canada: a population-based study.

BACKGROUND: The current study aimed to estimate the prevalence of alcohol use identified as a risk factor during pregnancies by the antenatal care providers, resulting in live births in British Columbia (BC) and to examine associations between alcohol use, adverse neonatal outcomes, and pregnancy complications. METHODS: This population-based cross-sectional study utilized linked obstetrical and neonatal records within the BC Perinatal Data Registry (BCPDR), for deliveries that were discharged between January 1, 2015 and March 31, 2018. The main outcome measures were alcohol use identified as a risk factor during pregnancy, associated maternal characteristics, pregnancy complications, and adverse neonatal outcomes. Estimates for the period and fiscal year prevalence were calculated. Chi-square tests were used to compare adverse neonatal outcomes and pregnancy complications by alcohol use during pregnancy identified as a risk factor. Logistic regression was used to examine the association between alcohol use identified as a risk factor during pregnancy and adverse neonatal outcomes and pregnancy complications, after adjusting for identified risk factors. RESULTS: A total of 144,779 linked records within the BCPDR were examined. The period prevalence of alcohol use during pregnancy identified as a risk factor was estimated to be 1.1% and yearly prevalence was 1.1, 1.1, 1.3 and 0.9% from the 2014/2015 to 2017/2018 fiscal years, respectively. Alcohol use identified as a risk factor was associated with younger maternal age, fewer antenatal visits, being primiparous, a history of mental illness, substance use and smoking. Neonates with alcohol use during pregnancy identified as a risk factor had greater odds of being diagnosed with: "low birth weight (1000-2499g)" (ICD-10: P07.1; aOR = 1.25; 95% CI: 1.01, 1.53), "other respiration distress of newborn" (ICD-10: P22.8; aOR = 2.57; 95% CI: 1.52, 4.07), "neonatal difficulty in breastfeeding" (ICD-10: P92.5; aOR = 1.97; 95% CI: 1.27, 2.92) and "feeding problems, unspecified" (ICD-10: P92.9; aOR = 2.06; 95% CI: 1.31, 3.09). CONCLUSIONS: The prevalence of alcohol use during pregnancy identified as a risk factor was comparable to previous estimates within the BCPDR. Identified prenatal alcohol exposure was associated with notable differences in maternal and neonatal characteristics and adverse neonatal outcomes. More consistent, thorough screening and prevention efforts targeting alcohol use in pregnancy are urgently needed in Canada.

Maternal risk of hypertension 7-15 years after pregnancy: clues from the placenta.

OBJECTIVE: To assess whether pre-eclampsia (PE)-related placental/extraplacental membrane findings are linked to moderately elevated blood pressure (BP) in pregnancy and later-life hypertension. DESIGN: Prospective cohort. SETTING: 52 prenatal clinics, 5 Michigan communities. SAMPLE: The POUCH Study recruited women at 16-27 weeks' gestation (1998-2004) and studied a sub-cohort in depth. This sample (n = 490) includes sub-cohort women with detailed placental assessments and cardiovascular health evaluations 7-15 years later in the POUCHmoms follow-up study. METHODS: PE-related placental/extraplacental membrane findings (i.e. mural hyperplasia, unaltered/abnormal vessels or atherosis in decidua; infarcts) were evaluated in relation to pregnancy BP and odds of Stage 2 hypertension at follow up using weighted polytomous regression. Follow-up hypertension odds also were compared in three pregnancy BP groups: normotensives (referent) and moderately elevated BP with or without PE-related placental/extraplacental membrane findings. MAIN OUTCOME MEASURES: Stage 2 hypertension (SBP ≥140 mmHg and/or DBP ≥90 mmHg, or using antihypertensive medications) at follow up. RESULTS: After excluding women with pregnancy hypertension (i.e. chronic, PE, gestational), mural hyperplasia and unaltered/abnormal decidual vessels were each associated with Stage 2 hypertension at follow up: adjusted odds ratio (aOR) = 2.7, 95% CI 1.1-6.6, and aOR = 1.7 (95% CI 0.8-3.4), respectively. Women with moderately elevated BP in pregnancy and evidence of mural hyperplasia or unaltered/abnormal decidual vessels had greater odds of Stage 2 hypertension at follow up: aOR = 4.5 (95% CI 1.6-12.5 and aOR = 2.6, 95% CI 1.1-5.9, respectively. CONCLUSIONS: PE-related placental/extraplacental membrane findings help risk-stratify women with moderately elevated BP in pregnancy for later development of hypertension. TWEETABLE ABSTRACT: Placental findings associated with mother's risk of later-life hypertension.

Universal screening for SARS-CoV-2 in pregnant women at term admitted to an East London maternity unit.

OBJECTIVE: To explore the prevalence of asymptomatic SARS-CoV-2 in the maternity population. STUDY DESIGN: Newham University Hospital based in East London serving a population with the highest death rate secondary to SARS-CoV-2 in the UK, commenced universal screening of all admissions to the Maternity Unit from 22nd April to 5th May, 2020. A proforma was created to capture key patient demographics, indication for admission and presence of SARS-CoV-2 related symptoms at the point of presentation. RESULTS: A total of 180 women with a mean age of 29.9 (SD 7.4) years, at a median gestation of 39 (IQR 37 + 1-40 + 3) weeks underwent universal screening with nasopharyngeal PCR swabs during the two-week period of the study. BAME identity or parity was not associated with the likelihood of a positive result. Seven women (3.9 %, 1.6-7.8) were tested positive for SARS-CoV-2, of whom 6 (3.3 %, 1.2-7.1) were asymptomatic; 85.7 % (42.1-99.6) of the SARS-CoV-2 positive women were asymptomatic. The sensitivity of symptom-driven testing was 14.3 % (0.36-57.87) and specificity was 91.86 % (86.72-95.48) with a positive predictive value of 6.67 % (1.08-31.95) and a negative predictive value of 96.34 % (95.10-97.28). CONCLUSION: The prevalence of SARS-CoV-2 in the maternity population served by Newham University Hospital was 3.9 %, four weeks after lockdown. Of the women who were found to be SARS-CoV-2 positive, a high proportion (87.9 %) were asymptomatic. These findings support the need for universal testing to enable targeted isolation and robust infectious control measures to mitigate outbreaks of SARS-CoV-2 in maternity units.
