Abstract
PURPOSE Intraoperative cell salvage is central to Patient Blood Management including for lower segment caesarean section. Prior to April 2020, we initiated intraoperative cell salvage during caesarean section based on risk assessment for hemorrhage and patient factors. As the pandemic broadened, we mandated intraoperative cell salvage to prevent peri-partum anemia and potentially reduce blood product usage. We examined the association of routine intraoperative cell salvage on maternal outcomes. METHODS We conducted a single-center non-overlapping before-after study of obstetric patients undergoing lower segment caesarean section in the 2 months prior to a change in practice ('usual care = selective intraoperative cell salvage', n = 203) and the 2 months following ('mandated intraoperative cell salvage', n = 228). Recovered blood was processed when a minimal autologous reinfusion volume of 100 ml was expected. Post-operative iron infusion and length of stay were modelled using logistic or linear regression, using inverse probability weighting to account for confounding. RESULTS More emergency lower-segment caesarean sections occurred in the Usual Care group. Compared to the Usual Care group, post-operative hemoglobin was higher and anemia cases fewer in the Mandated intraoperative cell salvage group. Rates of post-partum iron infusion were significantly lower in the Mandated intraoperative cell salvage group (OR = 0.31, 95% CI = 0.12 to 0.80, P = 0.016). No difference was found for length of stay. CONCLUSION Routine cell salvage provision during lower segment caesarean section was associated with a significant reduction in post-partum iron infusions, increased post-operative hemoglobin and reduced anemia prevalence.

Abstract
BACKGROUND Severe maternal morbidity is a composite indicator of maternal health and obstetrical care. Little is known about the risk of recurrent severe maternal morbidity in a subsequent delivery. OBJECTIVE This study aimed to estimate the risk of recurrent severe maternal morbidity in the next delivery after a complicated first delivery. STUDY DESIGN We analyzed a population-based cohort study of women with at least 2 singleton hospital deliveries between 1989 and 2021 in Quebec, Canada. The exposure was severe maternal morbidity in the first hospital-recorded delivery. The study outcome was severe maternal morbidity at the second delivery. Log-binomial regression models adjusted for maternal and pregnancy characteristics were used to generate relative risks and 95% confidence intervals comparing women with and without severe maternal morbidity at first delivery. RESULTS Among 819,375 women, 43,501 (3.2%) experienced severe maternal morbidity in the first delivery. The rate of severe maternal morbidity recurrence at second delivery was 65.2 vs 20.3 per 1000 in women with and without previous severe maternal morbidity (adjusted relative risk, 3.11; 95% confidence interval, 2.96-3.27). The adjusted relative risk for recurrence of severe maternal morbidity was greatest among women who had ≥3 different types of severe maternal morbidity at their first delivery, relative to those with none (adjusted relative risk, 5.50; 95% confidence interval, 4.26-7.10). Women with cardiac complication at first delivery had the highest risk of severe maternal morbidity in the next delivery. CONCLUSION Women who experience severe maternal morbidity have a relatively high risk of recurrent morbidity in the subsequent pregnancy. In women with severe maternal morbidity, these study findings have implications for prepregnancy counseling and maternity care in the next pregnancy.

Abstract
Background After pregnancy, patients with preexisting heart disease are at high risk for cardiovascular complications. The primary objective was to compare the incidence of new hypertension after pregnancy in patients with and without heart disease. Methods and Results This was a retrospective matched-cohort study comparing the incidence of new hypertension after pregnancy in 832 patients who are pregnant with congenital or acquired heart disease to a comparison group of 1664 patients who are pregnant without heart disease; matching was by demographics and baseline risk for hypertension at the time of the index pregnancy. We also examined whether new hypertension was associated with subsequent death or cardiovascular events. The 20-year cumulative incidence of hypertension was 24% in patients with heart disease, compared with 14% in patients without heart disease (hazard ratio [HR], 1.81 [95% CI, 1.44-2.27]). The median follow-up time at hypertension diagnosis in the heart disease group was 8.1 years (interquartile range, 4.2-11.9 years). The elevated rate of new hypertension was observed not only in patients with ischemic heart disease, but also in those with left-sided valve disease, cardiomyopathy, and congenital heart disease. Pregnancy risk prediction methods can further stratify risk of new hypertension. New hypertension was associated with an increased rate of subsequent death or cardiovascular events (HR, 1.54 [95% CI, 1.05-2.25]). Conclusions Patients with heart disease are at higher risk for developing hypertension in the decades after pregnancy when compared with those without heart disease. New hypertension in this young cohort is associated with adverse cardiovascular events highlighting the importance of systematic and lifelong surveillance.

Abstract
OBJECTIVE We studied the association between gestational diabetes mellitus and early versus late childhood cancer. RESEARCH DESIGN AND METHODS We conducted a retrospective cohort study of 1 million children born between 2006 and 2019 in Quebec, Canada. We identified children who were exposed to gestational diabetes mellitus in utero and followed them from birth up to 14 years of age to identify new-onset cancers. We estimated hazard ratios (HRs) for the association between gestational diabetes mellitus and childhood cancer using Cox proportional regression models with adjustment for covariates through inverse propensity score weights. RESULTS A total of 83,626 children (8.2%) were exposed to gestational diabetes mellitus, and 1,702 developed cancer during 7.6 million person-years of follow-up. Children exposed to gestational diabetes mellitus had a higher risk of any cancer (HR 1.19, 95% CI 1.01-1.40), with signals present for blood cancer (HR 1.27, 95% CI 0.92-1.76) and solid tumors (HR 1.14, 95% CI 0.94-1.40). The association between gestational diabetes mellitus and cancer was strongest early in life and decreased with age. Gestational diabetes mellitus was associated with 1.47 times the risk of any cancer (95% CI 1.21-1.79), 1.44 times the risk of solid cancer (95% CI 1.12-1.87), and 1.61 times the risk of blood cancer (95% CI 1.09-2.36) in children age <2 years. Gestational diabetes mellitus was not significantly associated with blood or solid cancers after 2 years of age, and all associations disappeared after 6 years. CONCLUSIONS Hyperglycemia may be carcinogenic in utero and may be a novel risk factor for early childhood cancer.

Long-term effects of preeclampsia on metabolic and biochemical outcomes in offspring: What can be expected from a meta-analysis? Obes Rev 2022; 23:e13411. [PMID: 34907632 DOI: 10.1111/obr.13411] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/23/2021] [Revised: 11/29/2021] [Accepted: 11/30/2021] [Indexed: 11/29/2022]
Abstract
The objective of this study is to evaluate the long-term effects of preeclampsia (PE) on metabolic and biochemical outcomes in offspring. We searched PubMed-Medline, Web of Science, and EMBASE from inception to June 2021 for randomized clinical trials, cohort, and case-control studies. Two researchers independently extracted data according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines and assessed possible bias. Rate ratios (RRs) or weighted mean differences (WMDs) were estimated using fixed-effects model or random-effects model if the heterogeneity was high. PE increased offspring risk of obesity (RR 1.45, 95% confident interval [CI] 1.19-1.78) with a mean weighted age of 9.1 years, and a higher body mass index from 10 years of age (WMD 0.46, 95% CI 0.08-0.83). PE offspring were associated with a higher mean arterial pressure (WMD 1.33, 95% CI 0.42-2.24), systolic blood pressure (WMD 1.93, 95% CI 1.48-2.37), and diastolic blood pressure (WMD 1.13, 95% CI 0.80-1.47) in puberty. However, we uncovered no association between PE and offspring levels of total cholesterol, triglycerides, high-density lipoprotein, low-density lipoprotein, glucose, and insulin in blood with puberty, nor was there an increase in the risk of type 1 diabetes mellitus in PE offspring under 15 years of age (RR 1.07, 95% CI 0.88-1.32). However, PE might be associated with central obesity, hypertension, and type 2 diabetes mellitus of offspring in later life. Offspring of mothers with PE exhibited an increased risk of obesity in childhood and a higher body mass index and blood pressure in puberty, but there were no differences in blood lipids or glucose metabolism in puberty compared to non-PE offspring. PE might be associated with a higher risk for central obesity, hypertension, and type 2 diabetes mellitus of offspring in later life.

Abstract
BACKGROUND Severe maternal morbidity is rising, yet the association with cardiovascular disease is not clear. We examined the risk of cardiovascular hospitalization up to 3 decades after having a pregnancy complicated by severe maternal morbidity. METHODS We analyzed a longitudinal cohort of 1 336 846 women who were pregnant between 1989 and 2019 in Quebec, Canada. The main exposure measure was severe maternal morbidity in any pregnancy, including severe preeclampsia, acute renal failure, sepsis, and other life-threatening conditions. Using time-varying Cox regression models, we compared the adjusted risk of hospitalization for cardiovascular disease up to 3 decades after pregnancy for women with severe maternal morbidity relative to women without severe morbidity. RESULTS Five percent of women had severe maternal morbidity. Overall, there were 68 287 cardiovascular hospitalizations during 21 725 672 person-years of follow-up in the cohort. Compared with no morbidity, women with any severe morbidity had a greater risk of cardiovascular hospitalization (hazard ratio [HR], 1.77 [95% CI, 1.72-1.82]). The association was the greatest within the first year of delivery (HR, 4.42 [95% CI, 3.77-5.19]) but persisted beyond 15 years (HR, 1.44 [95% CI, 1.37-1.51]). Having a cardiac complication (HR, 5.37 [95% CI, 4.65-6.20]), cerebrovascular accident (HR, 3.82 [95% CI, 2.94-4.96]), or acute renal failure (HR, 2.60 [95% CI, 2.15-3.14]) during pregnancy was strongly associated with future cardiovascular hospitalization. CONCLUSIONS Women with severe maternal morbidity have a greater risk of cardiovascular disease after pregnancy, both in the short and long term. These women may benefit from active surveillance for cardiovascular disease.

Abstract
Placental abruption and cardiovascular disease (CVD) have common etiological underpinnings, and there is accumulating evidence that abruption may be associated with future CVD. We estimated associations between abruption and coronary heart disease (CHD) and stroke. The meta-analysis was based on the random-effects risk ratio (RR) and 95% confidence interval (CI) as the effect measure. We conducted a bias analysis to account for abruption misclassification, selection bias, and unmeasured confounding. We included 11 cohort studies comprising 6,325,152 pregnancies, 69,759 abruptions, and 49,265 CHD and stroke cases (1967-2016). Risks of combined CVD morbidity-mortality among abruption and nonabruption groups were 16.7 and 9.3 per 1,000 births, respectively (RR = 1.76, 95% CI: 1.24, 2.50; I2 = 94%; τ2 = 0.22). Women who suffered abruption were at 2.65-fold (95% CI: 1.55, 4.54; I2 = 85%; τ2 = 0.36) higher risk of death related to CHD/stroke than nonfatal CHD/stroke complications (RR = 1.32, 95% CI: 0.91, 1.92; I2 = 93%; τ2 = 0.15). Abruption was associated with higher mortality from CHD (RR = 2.64, 95% CI: 1.57, 4.44; I2 = 76%; τ2 = 0.31) than stroke (RR = 1.70, 95% CI: 1.19, 2.42; I2 = 40%; τ2 = 0.05). Corrections for the aforementioned biases increased these estimates. Women with pregnancies complicated by placental abruption may benefit from postpartum screening or therapeutic interventions to help mitigate CVD risks.

Abstract
OBJECTIVE To investigate the long-term risk of developing hypertension and cardiovascular disease (CVD) among those women who suffered a postpartum haemorrhage (PPH) compared with those women who did not. DESIGN Population-based longitudinal open cohort study. SETTING English primary care (The Health Improvement Network (THIN)) and secondary care (Hospital Episode Statistics (HES)) databases. POPULATION Women exposed to PPH during the study period matched for age and date of delivery, and unexposed. METHODS We conducted an open cohort study using linked primary care THIN and HES Databases, from 1 January 1997 to 31 January 2018. A total of 42 327 women were included: 14 109 of them exposed to PPH during the study period and 28 218 matched for age and date of delivery, and unexposed to PPH. HRs for cardiovascular outcomes among women who had and did not have PPH were estimated after controlling for covariates using multivariate Cox regression models. OUTCOME MEASURES Risk of hypertensive disease, ischaemic heart disease, heart failure, stroke or transient ischaemic attack. RESULTS During a median follow-up of over 4 years, there was no significant difference in the risk of hypertensive disease after adjustment for covariates (adjusted HR (aHR): 1.03 (95% CI: 0.87 to 1.22); p=0.71). We also did not observe a statistically significant difference in the risk of composite CVD (ischaemic heart disease, heart failure, stroke or transient ischaemic attack) between the exposed and the unexposed cohort (aHR: 0.86 (95% CI: 0.52 to 1.43; p=0.57). CONCLUSION Over a median follow-up of 4 years, we did not observe an association between PPH and hypertension or CVD.

Abstract
PURPOSE The association between placental detachment disorders and risk of chronic disease is unclear. We determined the association of placenta accreta and retained placenta with risk of future maternal cardiovascular disease and cancer. METHODS We tracked a longitudinal cohort of 541,051 pregnant women over a period of 13 years (2006-2019) in Quebec, Canada. The main exposure measures were placenta accreta and retained placenta in any pregnancy. Outcomes included future hospitalizations for cardiovascular disease and cancer. Using Cox regression models adjusted for maternal characteristics, we estimated hazard ratios (HR) and 95% confidence intervals (CI) for the association of accreta and retained placenta with cardiovascular disease and cancer at 13 years. RESULTS The incidence of cardiovascular hospitalization was 21.2 per 10,000 person-years for accreta and 23.4 per 10,000 for retained placenta with postpartum hemorrhage, compared with 20.3 per 10,000 for neither placental disorder. Cancer incidence followed a similar pattern, with rates highest for retained placenta with hemorrhage. Retained placenta with hemorrhage was associated with 1.19 times the risk of cardiovascular disease (95% CI 1.03-1.38) and 1.27 times the risk of cancer (95% CI 1.06-1.53). Retained placenta with hemorrhage was associated with heart failure (HR 1.84, 95% CI 1.04-3.27), cardiomyopathy (HR 1.88, 95% CI 1.03-3.43), and cervical cancer (HR 2.03, 95% CI 1.17-3.52). Accreta and retained placenta without hemorrhage were not associated with these outcomes. CONCLUSION Retained placenta with hemorrhage may be a risk marker for cardiovascular disease and certain cancers later in life.
