We examined the influence of dietary α-lipoic acid (LA; R enantiomer) supplementation in obese-complicated pregnancies on maternal postpartum body weight and metabolic health. Forty-eight female Sprague-Dawley rats were randomized into three dietary groups throughout pre-pregnancy, gestation, and lactation: (i) a low-calorie control diet (CON); (ii) a high calorie obesity-inducing diet (HC); or (iii) the HC diet with 0.25% LA (HC+LA). Following offspring weaning, all mothers were switched to the CON diet for a postpartum period of 140 days to assess maternal body weight and markers of metabolic health. HC-fed mothers showed excessive (p < 0.05) gestational weight gain (GWG), higher (p < 0.05) postpartum body weight, reduced (p < 0.05) glycemic control (lower glucose:insulin ratio) and higher (p = 0.06) hepatic cholesterol concentration versus CON mothers. In contrast, HC+LA mothers demonstrated lower (p < 0.05) body weight throughout the experimental period compared with HC mothers, primarily due to a marked reduction in GWG. Although LA did not protect (p > 0.05) against reduced glycemic control, it did alter several aspects of lipid metabolism including reduced serum HDL-C and a lower concentration of hepatic cholesterol which was mediated partly through a reduction in low-density lipoprotein receptor expression. We conclude that maternal obesity during pregnancy leads to a longer-term detrimental impact on weight gain and glycemic control, even after switching to a low-calorie postpartum diet. Maternal LA supplementation may be able to partially offset these effects, likely by protecting against excessive GWG during pregnancy. However, further work is required to determine the consequences of reduced serum HDL-C in LA-supplemented mothers.

Women have been entering pregnancy less healthy than previous generations, placing them at increased risk for pregnancy complications. One approach to ensuring effective monitoring and treatment of at-risk women is designing technology-based interventions that prevent maternal morbidities and treat perinatal conditions.

This scoping review evaluates what informatics interventions have been designed and tested to prevent and treat maternal morbidity.

MEDLINE, Embase, and Cochrane Library were searched to identify relevant studies. The inclusion criteria were studies that tested a medical or clinical informatics intervention; enrolled adult women; and addressed preeclampsia, gestational diabetes mellitus (GDM), preterm birth, Centers for Disease Control and Prevention-defined severe maternal morbidity, or perinatal mental health conditions. Demographic, population, and intervention data were extracted to characterize the technologies, conditions, and populations addressed.

A total of 80 studies were identified that met the inclusion criteria. Many of the studies tested for multiple conditions. Of these, 73% (60/82) of the technologies were tested for either GDM or perinatal mental health conditions, and 15% (12/82) were tested for preeclampsia. For technologies, 32% (28/87) of the technologies tested were smartphone or tablet applications, 26% (23/87) were telehealth interventions, and 14% (12/87) were remote monitoring technologies. Of the many outcomes measured by the studies, almost half (69/140, 49%) were patient physical or mental health outcomes.

Per this scoping review, most informatics interventions address three conditions: GDM, preeclampsia, and mental health. There may be opportunities to treat other potentially lethal conditions like postpartum hemorrhage using proven technologies such as mobile apps. Ample gaps in the literature exist concerning the use of informatics technologies aimed at maternal morbidity. There may be opportunities to use informatics for lesser-targeted conditions and populations.

Recurrent pregnancy loss (RPL) is characterized by the occurrence of three or more consecutive spontaneous pregnancy losses before 20-24 weeks of gestation. Despite significant progress in the investigation of the biological pathways associated with unexplained RPL, the precise molecular mechanisms remain elusive. Recent advances in multi-omics approaches have identified numerous biomarkers that offer potential avenues for understanding the underlying complexities of RPL. The aim of this comprehensive literature review was to investigate the functional roles of these candidate markers and explore the possible key mechanisms that may contribute to RPL. We also aimed to elucidate the functional networks predicted by omics analyses, which hold promise for providing invaluable insights into novel diagnostic and therapeutic strategies for women experiencing RPL. Furthermore, this review expands on clinical implications and possible applications, highlighting those currently moving towards clinical use and ongoing studies developing in this direction.

While the perinatal period is a vulnerable time for women and their infants, it is also a window to promote adjustment and support. Women with intellectual disability might be a uniquely vulnerable group owing to pre-existing health and care inequalities. The aim of this paper is to explore the pregnancy and postnatal outcomes of women with intellectual disability and the health and development of their infants.

Three electronic databases (MEDLINE, PsycINFO, EMBASE) were searched for peer-reviewed papers that reported maternal pregnancy variables and infant outcomes within the first 12 months of life. Two reviewers screened 103 full text articles, of which nine met eligibility criteria. Data reporting maternal health, pregnancy complications, labour variables, and birth and neonatal outcomes were extracted, and findings were summarised narratively.

Women with intellectual disability were at an overall higher risk of adverse obstetric and pregnancy outcomes, such as urinary tract infection, gestational hypertension, and postpartum haemorrhage. Similarly, infants of women with intellectual disability had higher rates of premature birth, perinatal mortality, and experienced longer hospital stays when compared to their counterparts born to women without intellectual disability.

The relative sparsity of literature in this field demonstrates the need for further focused study on the pregnancy and postnatal outcomes of women with intellectual disability and their infants. Nonetheless, findings indicate that maternity services need to be further developed to provide optimum care for women with intellectual disability and to support infant development.

Maternal morbidity is higher among the Veteran population in part because of high rates of chronic medical and mental health conditions. To improve care for pregnant Veterans, the Department of Veteran Affairs created the position of the Maternity Care Coordinator (MCC) to provide care coordination during a Veteran's pregnancy. Maternity Care Coordinators must work with primary care providers (PCPs); yet, little is known about their collaboration and interaction. The objective of this work is to better understand how MCCs interact with PCPs.

Between March and May of 2021, we conducted qualitative interviews with 30 MCCs using a semi-structured interview guide to learn about their role and interactions with PCPs.

We identified 3 main themes in interactions between MCCs and PCPs, which correlated to times during the Veteran's pregnancy: initial interactions, care coordination during the pregnancy, and end of pregnancy transitions of care. Most MCCs indicated a positive and collaborative relationship with PCPs. There was significant variability in how closely MCCs worked with PCPs. MCCs reported that PCPs were not always comfortable caring for pregnant Veterans.

Although MCCs generally indicated a positive and collaborative interaction with PCPs, our data suggest that there are opportunities to improve communication between PCPs and MCCs and to educate PCPs on knowledge of maternity benefits, the role of the MCC, and how to care for pregnant and postpartum Veterans. The Veteran Affairs MCC can also serve as a model for other health systems aiming to improve care coordinator among pregnant patients.

Non-communicable chronic disease is a major contributor to morbidity and mortality with potentially modifiable lifestyle factors. In women, the menopausal transition modifies women's risk of chronic disease, and pregnancy-related complications have been highlighted as female-specific risk factors. Later reproductive years, before onset of menopause, may represent a window of opportunity for promotion of lifestyle modifications. The aim of this scoping review is to investigate which interventions promoting lifestyle modifications in women of later reproductive years may influence cardiometabolic and bone disease.

A search of three electronic databases (PubMed, Embase, CINAHL) in the English language was performed in January 2024. Eligible studies included women aged 40-55 participating in interventions focusing on lifestyle modification. Studies reporting outcomes related to cardiometabolic disease, bone disease or body composition were eligible for inclusion.

Improvements in body composition occurred following interventions focusing on aerobic physical activity. Interventions focusing on health promotion and education, incorporating both dietary and physical activity modifications, prevented weight gain and improved cardiometabolic outcomes. Interventions incorporating elements of behavioural theories enhanced patient-motivated lifestyle modifications, with effects on body composition and cardiometabolic outcomes.

Lifestyle modifications in later reproductive years have the potential to influence cardiometabolic and bone disease. Our findings reinforce the benefits of regular aerobic physical activity, as well as health education, for improving body composition and lipid profile. This information could contribute to the development of clinical guidelines for the prevention of chronic disease.

Pregnancy leads to a number of structural and functional changes in the urinary system, which makes females susceptible to urological complications. This review aims to discuss the epidemiology, complications and prevention and management of urinary tract infections (UTIs), kidney stones and bladder dysfunction in pregnancy. UTIs are the most common urological problem presenting in 10% of pregnant women; Escherichia coli is the most common causative organism. If left untreated, UTIs lead to acute pyelonephritis which occurs in about 2% of pregnant women and which has serious consequences for both the mother and the baby. Kidney stones, although rare, are hazardous, occurring in 1 in 200 to 1 in 1500 pregnancies, and may cause obstructive uropathy, and aggravation of "labor-like" pain. Urological complications are frequent in pregnancy; bladder dysfunction alone has been documented to affect 50% of the pregnant women. Urological complications can have severe consequences when not properly managed including preterm labor and renal dysfunction. In order to have the best pharmacological care, safe use of antibiotics for UTIs is needed along with other measures for kidney stones. This review highlights the importance of a team approach to patient management to optimize outcome and touches briefly on some of the ethical dilemmas that may be encountered when drug therapy in pregnancy is being considered. Therefore, it is feasible to enhance the health of women and the fetus during this period through patient focused care and innovative interventions.

Pregnancy issues such as gestational hypertension, preeclampsia, and gestational diabetes mellitus (GDM) are significant contributors to long-term cardiovascular diseases (CVDs) in women. Recent research has proved the impact of exercise on improving cardiovascular outcomes, particularly in women with pregnancy-related disorders. This review explores the outcomes of various exercise interventions on cardiovascular health in pregnant women. Among these, aerobic exercise has been widely studied, with results from observational studies and randomized controlled trials (RCTs) showing its positive outcomes on cardiovascular health in pregnant women, especially with complications. It has been found that regular aerobic exercise has been associated with reduced hypertension and improved endothelial function, particularly in women with a history of preeclampsia. Evidently, aerobic exercise results in better blood pressure regulation and enhanced vascular health that directly attends to the risk of cardiovascular diseases associated with pregnancy complications. Another form of exercise is resistance training, which despite being studied less, has shown potential benefits as well. Some advantages of resistance exercise have been found to improve muscle strength and overall enhancement in metabolic control. This is important, especially in women with GDM whereby improvement in insulin sensitivity reduces the overall risk of type 2 diabetes and future CVDs. Combined exercise that incorporates both aerobic and resistance elements has been known to offer the most comprehensive benefits. Various studies suggest that a combinatory approach maximizes the positive cardiovascular effects. Practicing women have experienced better overall heart health, with improved blood pressure regulation, enhanced endothelial function, and reduced metabolic risks. However, despite these findings, there are challenges such as small sample sizes and limited follow-up durations that hinder the generalizability of current research. Importantly, previous studies targeting exercise interventions for women experiencing complications during pregnancy have been limited in evidence by small sample sizes, short follow-ups, and lack of diversity. Such broader, more diverse populations were needed to reflect the various health risks and responses to exercise. Future research must include multi-center RCTs, diverse exercise regimens, and digital health tools for monitoring exercise adherence. This warrants future large-scale, multicenter trials that are necessary to establish more definitive evidence. Additionally, clinicians should consider including tailored exercise programs in care plans for women with pregnancy complications to mitigate long-term cardiovascular risks.

Pregnancy and early childhood cohorts provide a framework for investigating the complex interplay between early-life exposures and health outcomes, thereby informing prevention strategies and interventions to improve maternal and child health. In this paper, we outline the objectives, methodologies and expected contributions of INSIGHT-2, a comprehensive cohort study dedicated to advancing our understanding of pregnancy and pregnancy complications towards improving the health and well-being of mothers and their offspring.

Over the course of 5 years, the study aims to establish a diverse cohort of 1700 pregnant women and to follow up their children up to 2 years of age. Recruitment targets participants with healthy pregnancies, preexisting conditions, and/or risk factors for pregnancy complications or later child health problems. Clinical and lifestyle data and a range of biological samples will be collected, providing a comprehensive resource for biomarker investigations and cross-sectional analyses. It is anticipated that the cohort will continue beyond this initial 5-year plan.

By gathering a wide range of biological samples and using diverse analytical techniques, this study supports broad participation, potential replication and collaboration across various sites. The extensive collection of longitudinal data and samples not only facilitates current investigations but also establishes a biobank for future research. The exploration of pre-pregnancy and pregnancy factors that may contribute to disease processes and impact fetal well-being and future health will provide a comprehensive picture of disease mechanisms in both mothers and children, facilitating the identification of biomarkers for the prediction, diagnosis, and management of pregnancy complications. Additionally, our diverse population allows for the capture of various pregnancy complications and outcomes, enhancing external validity and addressing health disparities. This comprehensive design ultimately aims to improve maternal and child health outcomes by providing a valuable longitudinal study of the relationships among the in utero environment, pregnancy management, and long-term maternal and child health, ensuring that findings are relevant and beneficial to a broader population.

Complying with 24 h movement behavior guidelines for pregnant women may prevent pregnancy complications. This single time point, cross-sectional investigation assessed compliance with the 24 h movement behavior guidelines in pregnant women in Saudi Arabia and examined the role of trimester and maternal characteristics.

Pregnant women (n = 935; age = 30 ± 5.6 years; first trimester = 24.1%, second trimester = 33.9%, third trimester = 42.0%) self-reported their characteristics (nationality, region, degree, occupation, smoking status, health status, having children, previous birth). The short-version International Physical Activity Questionnaire, Sedentary Behavior Questionnaire, and Pittsburgh Sleep Quality Index Questionnaire measured moderate physical activity (MPA), sedentary behavior (SB), and sleep duration, respectively. Compliance with the 24 h movement behavior guidelines was reported using frequencies and percentages. Prevalence ratios compared the prevalence of compliance by trimester and maternal characteristics.

Approximately half of the participants did not comply with MPA or sleep duration guidelines (n = 524, [56.0%] and n = 424, [45.5%], respectively). In contrast, about two-thirds of participants (n = 648, [69.3%]) adhered to the SB guideline. Only 154 (16.5%) participants complied with all 3 24 h movement behavior guidelines. Pregnant women in their second trimester, living in Al-Ahsa Governorate, and currently smoking with a bachelor's degree were the most likely to comply with the guidelines.

These findings underscore the need for tailored efforts to promote healthy 24 h movement behavior guidelines for pregnant women in Saudi Arabia, especially early in pregnancy, while accounting for important maternal characteristics.

A history of hypertensive disorders of pregnancy is associated with at least twice the risk of incident ischemic heart disease. Whether the long-term outcome following treatment with coronary artery stenting is associated to the history of hypertensive disorders of pregnancy is unknown.

We included 8364 women (age ≤65 years) undergoing first coronary artery stenting 2006 to 2022 following their first delivery in 1973 or later, linking nationwide data on percutaneous coronary intervention and delivery history. In total, 1122 women (13.4%) had a history of hypertensive disorders of pregnancy. The main outcome, a major adverse cardiovascular event, was defined as any incident myocardial infarction, ischemic heart disease, cardiac arrest, arrhythmias, angina pectoris, heart failure, cerebral infarction, or sudden death. During a median follow-up time of 5 years, 258 women with a history of hypertensive disorders of pregnancy had a major adverse cardiovascular event, compared with 1465 women without a history of hypertensive disorders of pregnancy (23% versus 20.2%, P=0.028 for log-rank test). Estimates adjusted for patient- and procedural characteristics in proportional hazards regression models suggested that the hazard rate increased only after 4-8 years of follow-up (hazard ratio [HR], 1.36 [95% CI, 1.05-1.78]) and was primarily driven by women with history of gestational hypertension (HR, 2.15 [95% CI, 1.49-3.11]).

Women with a history of hypertensive disorders of pregnancy have an increased risk of a major adverse cardiovascular event following coronary artery stenting compared with other parous women. A history of hypertensive disorders of pregnancy warrants further attention in the secondary prevention setting of coronary artery disease.

Adverse pregnancy outcomes (APO) have been related to increased cardiovascular (CV) risk and mortality in later life. Underlying pathomechanisms for the development of CV disease in these women are not yet fully understood. In this study, we aimed to investigate the relationship between APO and individual CV risk profiles in later life.

We used cross-sectional data from 10,000 participants enrolled in the Hamburg City Health Study (HCHS). We analysed self-reported APO, CV risk factors and health status, including biomarkers, electrocardiogram, echocardiography and vascular ultrasound. To examine associations, Wilcoxon rank sum test and Pearson's χ2-test were performed. Multivariable-adjusted regression models were calculated to determine associations.

N = 1970 women who reported pregnancies were included. Median age was 63 years, 8.7 % reported gestational hypertension (gHTN), 18 % excessive weight gain and 2.4 % gestational diabetes. Ten percent had delivered newborns with birth weight <2.5 kg, 14 % newborns with birth weight >4 kg. In multivariable-adjusted models, significant associations between APO, CV risk profiles and cardiac remodeling were identified. gHTN correlated with higher body mass index (BMI) (Beta 1.68, CI 95 % 0.86-2.50; p < 0.001), hypertension (OR 4.58, CI 95 % 2.79-7.86; p < 0.001), left ventricular remodeling (e.g. left ventricular mass index (Beta 4.46, CI 95 % 1.05-7.87; p = 0.010)) and myocardial infarction (OR 3.27, CI 95 % 0.94-10.07; p = 0.046).

In this population-based sample, APO were associated with CV risk profiles and cardiac remodeling in later life, suggesting early manifestations of future CV risk during pregnancy. Prospective data is needed for individual risk stratification in women with APO.

Pregnancy complications might lead to the development of autoimmune diseases in women. This review aims to summarise studies evaluating the association between pregnancy complications and the development of autoimmune diseases in women.

Medline, CINAHL, and Cochrane databases were searched up to January 2024. Nineteen pregnancy complications and 15 autoimmune conditions were included. Title, abstract, full-text screening, data extraction, and quality assessment were performed by two reviewers independently. Data were synthesised using narrative and quantitative methods. Results were presented using odds ratios (OR), relative risks (RR), incidence rate ratios (IRR), and 95% confidence intervals (CI).

Thirty studies were included. One study reported composite exposure to pregnancy complications had a risk of any autoimmune disease RR 3.20 (2.90-3.51) compared to women without pregnancy complications. Women with hyperemesis gravidarum had a higher risk of developing coeliac disease (n = 1) IRR 1.98 (1.27-2.94), Crohn's disease (n = 1) IRR 1.61 (1.25-2.04), psoriasis (n = 1) IRR 1.33 (1.01-1.71), and rheumatoid arthritis (n = 2) IRR 1.35 (1.09-1.64). Miscarriage associated with subsequent diagnosis of Sjogren syndrome (n = 2) IRR 1.33 (1.06-2.81) and rheumatoid arthritis (n = 4) OR 1.11 (1.04-1.20). Gestational hypertension/preeclampsia was linked with the development of systemic sclerosis (n = 2) IRR 2.60 (1.10-4.60) and T1DM (n = 2) IRR 2.37 (2.09-2.68). Stillbirth associated with composite autoimmune conditions (n = 2) RR 5.82 (95% CI 4.87-6.81) and aIRR 1.25 (1.12-1.40). Postpartum psychosis was associated with autoimmune thyroid disease (n = 1) aIRR2.26 (1.61-2.90).

Women with pregnancy complications subsequently had a higher risk of being diagnosed with autoimmune conditions. Whether this is due to pre-existing undiagnosed health conditions or being causally linked to pregnancy complications is not known.

Over 250 million children are not reaching their developmental potential globally. The impact of prenatal factors and their interplay with postnatal environmental factors on child neurodevelopment, is still unclear-particularly in low- and middle-income settings. This study aims to understand the impact of pregnancy complications as well as environmental, psychosocial, and biological predictors on neurodevelopmental trajectories.

This is an observational cohort study of female and male children (≈3,950) born to women (≈4,200) with and without pregnancy complications (pregnancy-induced hypertension, foetal growth restriction, and premature birth) previously recruited into PREgnancy Care Integrating Translational Science, Everywhere study with detailed biological data collected in intrapartum and post-partum periods. Children will be assessed at six weeks to 6 months, 11-13 months, 23-25 months and 35-37 months in rural and semi-urban Gambia (Farafenni, Illiasa, and Ngayen Sanjal) and Kenya (Mariakani and Rabai). We will assess children's neurodevelopment using Prechtls General Movement Assessment, the Malawi Development Assessment Tool (primary outcome), Observation of Maternal-Child Interaction, the Neurodevelopmental Disorder Screening Tool, and the Epilepsy Screening tool. Children screening positive will be assessed with Cardiff cards (vision), Modified Checklist for Autism in Toddlers Revised, and Pediatric Quality of Life Inventory Family Impact. We will use multivariate logistic regression analysis to investigate the impact of pregnancy complications on neurodevelopment and conduct structural equation modelling using latent class growth to study trajectories and relationships between biological, environmental, and psychosocial factors on child development.

We aim to provide information regarding the neurodevelopment of infants and children born to women with and without pregnancy complications at multiple time points during the first three years of life in two low-resource African communities. A detailed evaluation of developmental trajectories and their predictors will provide information on the most strategic points of intervention to prevent and reduce the incidence of neurodevelopmental impairments.

Placental health and foetal development are dependent upon element homeostasis. Analytical techniques such as mass spectroscopy can provide quantitative data on element concentrations in placental tissue but do not show spatial distribution or co-localisation of elements that may affect placental function. The present study used synchrotron-based X-ray fluorescence microscopy to elucidate element content and distribution in healthy and pathological placental tissue. The X-ray fluorescence microscopy (XFM) beamline at the Australian Synchrotron was used to image trace metal content of 19 placental sections from healthy term (n = 5, 37-39 weeks), foetal growth-restricted (n = 3, <32 weeks, birth weight <3rd centile), postdate (n = 7, >41 completed weeks), and stillbirth-complicated pregnancies (n = 4, 37-40 weeks). Samples were cryo-sectioned and freeze-dried. The concentration and distribution of fourteen elements were detected in all samples: arsenic, bromine, calcium, chlorine, copper, iron, molybdenum, phosphorous, potassium, rubidium, selenium, strontium, sulphur, and zinc. The elements zinc, calcium, phosphorous, and strontium were significantly increased in stillbirth placental tissue in comparison to healthy-term controls. Strontium, zinc, and calcium were found to co-localise in stillbirth tissue samples, and calcium and strontium concentrations were correlated in all placental groups. Molybdenum was significantly decreased in stillbirth, foetal growth-restricted, and postdate placental tissue in comparison to healthy-term samples (p < 0.0001). Synchrotron-based XFM reveals elemental distribution within biological samples such as the placenta, allowing for the co-localisation of metal deposits that may have a pathological role. Our pilot study further indicates low concentrations of placental molybdenum in pregnancies complicated by foetal growth restriction, postdate delivery, and stillbirth.

Maternal common mental disorders have broad implications for maternal and child mental and physical health that may have a long-lasting social and economic impact. This study aimed to assess the association between symptoms of antenatal common mental disorders and obstetric and perinatal outcomes in Eastern Ethiopia.

A community-based prospective cohort study was conducted and a total of 1011 randomly selected pregnant women were followed up from February 1, 2021, to January 30, 2022. The modified Poisson regression model with a robust variance was fitted to examine the effect of the symptoms of antenatal common mental disorders on obstetric and perinatal outcomes.

Antenatal common mental disorders (SRQ ≥ 6) were presented among 390 (38.58 %) pregnant women. In the final multivariate Poisson regression model, women with antenatal common mental disorders symptoms had an increased risk of some pregnancy complications (ARR = 1.65, 95 % CI: 1.59, 1.84). In the current study, symptoms of antenatal common mental disorders increased also the risk of preterm birth (ARR = 1.71; 95 % CI: 1.20, 2.42) and low birth weight (ARR = 1.93; 95 % CI: 1.36, 2.74).

The indirect effects of some potential mediators and moderators were not assessed in this study.

The study found a high rate of symptoms of antenatal common mental disorders and adverse obstetric and perinatal outcomes. Antenatal common mental disorders symptoms may have considerable effects on individual and combined pregnancy complications and adverse perinatal outcomes.

Women Veterans are at increased risk for poor pregnancy outcomes and are increasingly using Veteran Affairs (VA) for maternity benefits. VA Women's Health Primary Care Providers (WH-PCPs) are well positioned to improve maternal outcomes for women Veterans, yet little is understood about their experience and comfort with perinatal care. The objective of this study was to develop and validate a survey that could be utilized to assess WH-PCPs' experience, comfort, and attitudes towards perinatal care.

After a review of the literature, we adapted a previously published survey to address four content areas including clinical experience, comfort level, and attitudes towards perinatal care and knowledge of VA specific maternity services. This survey was piloted with five WH-PCPs before undergoing two rounds of content validation with content experts. Content validity indexes (CVI) were calculated based on the content experts' ratings. Qualitative feedback from the content experts were summarized and reviewed by the research team. The CVI and qualitative responses were utilized to guide the decision to revise, refine, or delete survey questions.

After the first round of content validation, we deleted three questions, revised three questions, and add three questions to the content areas of clinical experience and comfort. In the domain of attitudes towards perinatal care, we deleted one question and revised two questions and three questions were added to the knowledge of VA specific maternity services domain. After the second round of content validation, only one question was deleted from the attitudes domain.

We developed and validated the Ready to Care Survey for VA WH-PCP using two rounds of content validation. The final survey had face and content validity. This survey tool can be used to assess VA WH-PCP's knowledge and readiness in caring for Veterans of child-bearing age for operational and research needs.

Despite many systematic reviews and meta-analyses examining the associations of pregnancy complications with risk of type 2 diabetes mellitus (T2DM) and hypertension, previous umbrella reviews have only examined a single pregnancy complication. Here we have synthesised evidence from systematic reviews and meta-analyses on the associations of a wide range of pregnancy-related complications with risk of developing T2DM and hypertension.

Medline, Embase and Cochrane Database of Systematic Reviews were searched from inception until 26 September 2022 for systematic reviews and meta-analysis examining the association between pregnancy complications and risk of T2DM and hypertension. Screening of articles, data extraction and quality appraisal (AMSTAR2) were conducted independently by two reviewers using Covidence software. Data were extracted for studies that examined the risk of T2DM and hypertension in pregnant women with the pregnancy complication compared to pregnant women without the pregnancy complication. Summary estimates of each review were presented using tables, forest plots and narrative synthesis and reported following Preferred Reporting Items for Overviews of Reviews (PRIOR) guidelines.

Ten systematic reviews were included. Two pregnancy complications were identified. Gestational diabetes mellitus (GDM): One review showed GDM was associated with a 10-fold higher risk of T2DM at least 1 year after pregnancy (relative risk (RR) 9.51 (95% confidence interval (CI) 7.14 to 12.67) and although the association differed by ethnicity (white: RR 16.28 (95% CI 15.01 to 17.66), non-white: RR 10.38 (95% CI 4.61 to 23.39), mixed: RR 8.31 (95% CI 5.44 to 12.69)), the between subgroups difference were not statistically significant at 5% significance level. Another review showed GDM was associated with higher mean blood pressure at least 3 months postpartum (mean difference in systolic blood pressure: 2.57 (95% CI 1.74 to 3.40) mmHg and mean difference in diastolic blood pressure: 1.89 (95% CI 1.32 to 2.46) mmHg). Hypertensive disorders of pregnancy (HDP): Three reviews showed women with a history of HDP were 3 to 6 times more likely to develop hypertension at least 6 weeks after pregnancy compared to women without HDP (meta-analysis with largest number of studies: odds ratio (OR) 4.33 (3.51 to 5.33)) and one review reported a higher rate of T2DM after HDP (hazard ratio (HR) 2.24 (1.95 to 2.58)) at least a year after pregnancy. One of the three reviews and five other reviews reported women with a history of preeclampsia were 3 to 7 times more likely to develop hypertension at least 6 weeks postpartum (meta-analysis with the largest number of studies: OR 3.90 (3.16 to 4.82) with one of these reviews reporting the association was greatest in women from Asia (Asia: OR 7.54 (95% CI 2.49 to 22.81), Europe: OR 2.19 (95% CI 0.30 to 16.02), North and South America: OR 3.32 (95% CI 1.26 to 8.74)).

GDM and HDP are associated with a greater risk of developing T2DM and hypertension. Common confounders adjusted for across the included studies in the reviews were maternal age, body mass index (BMI), socioeconomic status, smoking status, pre-pregnancy and current BMI, parity, family history of T2DM or cardiovascular disease, ethnicity, and time of delivery. Further research is needed to evaluate the value of embedding these pregnancy complications as part of assessment for future risk of T2DM and chronic hypertension.

For many pathologies associated with aging, female patients present with higher morbidity and more frequent adverse events from treatments compared to male patients. While preclinical models are the foundation of our mechanistic understanding of age-related diseases, the most common models fail to recapitulate archetypical female aging trajectories. For example, while over 70% of the top age-related diseases are influenced by the systemic effects of reproductive senescence, we found that preclinical studies that include menopausal phenotypes modeling those seen in humans make up <1% of published aging biology research. The long-term impacts of pregnancy, birthing and breastfeeding are also typically omitted from preclinical work. In this Perspective, we summarize limitations in the most commonly used aging models, and we provide recommendations for better incorporating menopause, pregnancy and other considerations of sex in vivo and in vitro. Lastly, we outline action items for aging biology researchers, journals, funding agencies and animal providers to address this gap.

Traumatic birth experience is an unaddressed arena, especially in Asian women, with several societal stigmas lingering around.

A study was undertaken to simultaneously assess the post-partum mental and physical health follow-up of maternal near-miss (MNM) women and compare it with women of uneventful deliveries.

The prospective cohort study enrolled 88 MNM women (case cohort) and 80 women with an uneventful peri-partum period (control cohort) at the same time. The participants were followed up with Edinburgh Postnatal Depression Scale (EDPS), PTSD Checklist - Civilian Version (PLC-C), and a 36-item short-form-survey form over 6 months after the delivery.

The case group had higher mean EPDS and PLC-C scores, with poor quality of life (QOL) performance, compared to the control group at 6 weeks and 3 months, and 6 months follow-up (P < 0.05). At the sixth-week follow-up visit, the study observed that 28 (31.8%) women from the case group required a psychiatry consultation compared to the control group with only two (2.5%) participants (P < 0.001). At 3 months, an evident difference was noted on various QOL parameters, such as limitations due to physical health and emotional problems, energy fatigue, general health, and health change parameters between the two groups (P < 0.05). The difference persisted at 6-month follow-up as well for limitations due to physical health, energy fatigue, and general health parameters only (P < 0.05).

There is an urgent need for a multi-departmental collaborative approach at the hospital level and policy-making decisions at higher levels for the mental health of Asian women facing MNM events.

By definition, aging is a natural, gradual and continuous process. On the other hand, frailty reflects the increase in vulnerability to stressors and shortens the time without disease (health span) while longevity refers to the length of life (lifespan). The average life expectancy has significantly increased during the last few decades. A longer lifespan has been accompanied by an increase in frailty and decreased independence in older adults, with major differences existing between men and women. For example, women tend to live longer than men but also experience higher rates of frailty and disability. Sex differences prevent optimization of lifestyle interventions and therapies to effectively prevent frailty. Sex differences in frailty and aging are rooted in a complex interplay between uncontrollable (genetic, epigenetic, physiological), and controllable factors (psychosocial and lifestyle factors). Thus, understanding the underlying causes of sex differences in frailty and aging is essential for developing personalized interventions to promote healthy aging and improve quality of life in older men and women. In this review, we have discussed the key contributors and knowledge gaps related to sex differences in aging and frailty.

Existing studies have established an association between pregnancy, birth complications, and mental health in the first few weeks postpartum. However, there is no clear understanding of whether pregnancy and birth complications increase the risk of adverse maternal mental outcomes in the longer term. Research on maternal adverse mental health outcomes following pregnancy and birth complications beyond 12 months postpartum is scarce, and findings are inconsistent.

This systematic review and meta-analysis will examine the available evidence on the association between pregnancy and birth complications and long-term adverse maternal mental health outcomes.

We will include cohort, cross-sectional, and case-control studies in which a diagnosis of pregnancy and/or birth complication (preeclampsia, pregnancy loss, caesarean section, preterm birth, perineal laceration, neonatal intensive care unit admission, major obstetric haemorrhage, and birth injury/trauma) was reported and maternal mental disorders (depression, anxiety disorders, bipolar disorders, psychosis, and schizophrenia) after 12 months postpartum were the outcomes. A systematic search of PubMed, Embase, CINAHL, PsycINFO, and Web of Science will be conducted following a detailed search strategy until August 2022. Three authors will independently review titles and abstracts of all eligible studies, extract data using pre-defined standardised data extraction and assess the quality of each study using the Newcastle-Ottawa Scale. We will use random-effects meta-analysis for each exposure and outcome variable to calculate overall pooled estimates using the generic inverse variance method. This systematic review will follow the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines.

The proposed systematic review and meta-analysis is based on published data; ethics approval is not required. The results will be presented at scientific meetings and publish in a peer-reviewed journal.

In this study, we investigated the immunohistochemical staining of SRY-box transcription factor 9 (SOX9) and Hif-1α expression in placentas of pregnant woman with hemolysis, elevated liver enzymes and low platelets (HELLP) syndrome.

Placentas of 20 normotensive and 20 women with HELLP syndrome were processed for routine histological tissue processing. The biochemical and clinical parameters of patients were recorded. Placentas were stained with hematoxylin-eosin and SOX9 and Hif-1α immunostaining.

Normotensive placentas showed normal histology of placenta, however placentas of HELLP syndrome showed intense thrombosis, thinning of the villi membrane and vascular dilatation. In placentas of normotensive patients, SOX9 reaction was immunohistochemically negative, however placentas of HELLP group showed SOX9 expression in decidual cells, and syncytial regions of floating villi and inflammatory cells. In placentas of normotensive patients, Hif-1α reaction was mainly negative in vessels and connective tissue cells. Placentas of HELLP group showed increased Hif-1α expression in decidual cell and especially inflammatory cells in the maternal region.

Hif-1α and SOX9 proteins can be used as a marker to show severity of preeclampsia and regulation of cell proliferation and angiogenesis during placental development.

Advancements in medical technology and pharmacologic interventions have drastically improved survival of infants born preterm and low birth weight, but knowledge regarding the long-term health impacts of these individuals is limited and inconsistent.

To investigate whether an individual's birthweight or history of being born preterm increases the risk of an adverse reproductive outcome.

Nested case-control study within the Women's Health Initiative.

79,934 individuals who self-reported their personal birthweight category and/or preterm birth status.

Self-reported pregnancy outcomes: subfertility, miscarriage, stillbirth, preeclampsia, gestational diabetes, gestational hypertension, preterm birth, low birthweight infant, high birthweight infant. Logistic regression models were used to estimate unadjusted and adjusted odds ratios (OR).

After adjustments, individuals reporting their birthweight <6lbs. were 20 % more likely to have a stillbirth or 70 % more likely to have a low birthweight infant and were less likely to have a full-term birth or high birthweight infant during their pregnancy. Individuals reporting a birthweight ≥10 lbs. were more likely to have a high birthweight infant (OR 3.49, 95 % CI 2.73-4.39) and less likely to have a low birthweight infant (OR 0.64, 95 % CI 0.47-0.82). Individuals born preterm were at increased risk for infertility, miscarriage, preeclampsia, gestational diabetes, and delivering a preterm or low birthweight infant.

As more individuals born preterm and/or low birthweight survive to adulthood, the incidence and prevalence of poor reproductive outcomes may increase. Women born at extremes of birthweight and prematurity may need to be monitored more closely during their own pregnancies.

Serving as the interface between fetal and maternal circulation, the placenta plays a critical role in fetal growth and development. Placental exosomes are small membrane-bound extracellular vesicles released by the placenta during pregnancy. They contain a variety of biomolecules, including lipids, proteins, and nucleic acids, which can potentially be biomarkers of maternal diseases. An increasing number of studies have demonstrated the utility of placental exosomes for the diagnosis and monitoring of pathological conditions such as pre-eclampsia and gestational diabetes. This suggests that placental exosomes may serve as new biomarkers in liquid biopsy analysis. This review provides an overview of the current understanding of the biological function of placental exosomes and their potential as biomarkers of maternal diseases. Additionally, this review highlights current barriers and the way forward for standardization and validation of known techniques for exosome isolation, characterization, and detection. Finally, microfluidic devices for exosome research are discussed.

Renal function increases in pregnancy due to the significant hemodynamic demands of plasma volume expansion and the growing feto-placental unit. Therefore, compromised renal function increases the risk for adverse outcomes for pregnant women and their offspring. Acute kidney injury (AKI), or sudden loss of kidney function, is a significant event that requires aggressive clinical management. An AKI event in pregnancy, or in the postpartum period, significantly increases the risk of adverse pregnancy events and fetal and maternal mortality. At present, there are significant clinical challenges to the identification, diagnosis, and management of pregnancy-associated AKI due to changing hemodynamics in pregnancy that alter baseline values and to treatment limitations in pregnancy. Emerging data indicate that patients that are considered clinically recovered following AKI, which is currently assessed primarily by return of plasma creatinine levels to normal, maintain risk of long-term complications indicating that current recovery criteria mask the detection of subclinical renal damage. In association, recent large-scale clinical cohorts indicate that a history of AKI predisposes women to adverse pregnancy events even years after the patient is considered recovered from AKI. Mechanisms via which women develop AKI in pregnancy, or develop adverse pregnancy events post-AKI, are poorly understood and require significant study to better prevent and treat AKI in women. © 2023 American Physiological Society.

The infant mortality rate (IMR) is an important reflection of the well-being of infants and the overall health of the population. This study aims to examine the macroeconomic (ME), sociodemographic (SD), and health status and resources (HSR) effects on IMR, as well as how they may interact with each other.

A retrospective time-series study using yearly data for Oman from 1980 to 2022. Partial Least Squares-Structural Equation Modelling (PLS-SEM) was utilized to develop the exploratory model of the determinants of IMR.

The model indicates that HSR determinants directly, but negatively, affect IMR (β = -0.617, p < 0.001). SD directly and positively affects IMR (β = 0.447, p < 0.001). ME only indirectly affects IMR (β = -0.854, p < 0.001). ME determinants also exert some direct influences on both HSR (β = 0.722, p < 0.001) and SD (β = -0.916, p < 0.001) determinants.

This study has indicated that IMR is a multi-faceted issue. It also highlighted the interplay of numerous variables and their influence on IMR, particularly the role that social status, the health sector, and the wealth of the country and its population play in reducing IMR. These findings indicate that an integrated policy that addresses socioeconomic and health-related factors and the overall ME environment is necessary for the health and well-being of the children and the population overall in Oman.

Observational studies suggest that chronotype is associated with pregnancy and perinatal outcomes. Whether these associations are causal is unclear.

To explore associations of a lifetime genetic predisposition to an evening preference chronotype with pregnancy and perinatal outcomes, and explore differences in associations of insomnia and sleep duration with those outcomes between chronotype.

We conducted two-sample Mendelian randomization (MR) using 105 genetic variants reported in a genome-wide association study (N=248 100) to instrument for lifelong predisposition to evening-versus morning-preference chronotypes. We generated variant-outcome associations in European ancestry women from UK Biobank (UKB, N=176 897), Avon Longitudinal Study of Parents and Children (ALSPAC, N=6826), Born in Bradford (BiB, N=2940) and Norwegian Mother, Father and Child Cohort Study (MoBa, with linked data from the Medical Birth Registry of Norway (MBRN), N=57 430), and extracted equivalent associations from FinnGen (N=190 879). We used inverse variance weighted (IVW) as main analysis, with weighted median and MR-Egger as sensitivity analyses. We also conducted IVW analyses of insomnia and sleep duration on the outcomes stratified by genetically predicted chronotype.

Self-reported and genetically predicted chronotype, insomnia and sleep duration.

Stillbirth, miscarriage, preterm birth, gestational diabetes, hypertensive disorders of pregnancy, perinatal depression, low birthweight and macrosomia.

In IVW and sensitivity analyses we did not find robust evidence of effects of chronotype on the outcomes. Insomnia was associated with a higher risk of preterm birth among evening preference women (odds ratio 1.61, 95% confidence interval: 1.17, 2.21), but not among morning preference women (odds ratio 0.87, 95% confidence interval: 0.64, 1.18), with an interaction P-value=0.01. There was no evidence of interactions between insomnia and chronotype on other outcomes, or between sleep duration and chronotype on any outcomes.

This study raises the possibility of a higher risk of preterm birth among women with insomnia who also have an evening preference chronotype. Our findings warrant replications due to imprecision of the estimates.

Question: Does an evening preference chronotype adversely affect pregnancy and perinatal outcomes? Is there an interaction between chronotype and either insomnia or sleep duration in relation to those outcomes?Findings: There was no evidence that evening preference was associated with pregnancy or perinatal outcomes. Women with a genetically predicted insomnia had a higher risk of preterm birth, if they also had a genetically predicted preference for evening chronotype.Meaning: The suggestive interaction between insomnia and evening preference on preterm birth, if replicated, supports targeting insomnia prevention in women of reproductive age with an evening chronotype.

Early and minimally invasive methods are required to predict the risk of multiple adverse pregnancy outcomes. A potential technique with growing interest utilizes the gingival crevicular fluid (GCF), a physiological serum exudate found in the healthy gingival sulcus and in the periodontal pocket in inflammatory conditions. Analysis of biomarkers in the GCF is a minimally invasive method that can be feasible and cost-effective. The potential use of GCF biomarkers along with other clinical indicators in early pregnancy may provide reliable predictors of several adverse pregnancy outcomes, therefore, reducing both maternal and fetal morbidities. Various studies have reported that increased or decreased concentrations of different biomarkers in GCF are associated with a high risk of developing pregnancy complications. In particular, such associations have been commonly demonstrated with gestational diabetes, pre-eclampsia, and pre-term birth. However, limited evidence is available regarding other pregnancy complications such as preterm premature rupture of membranes, recurrent miscarriage, small for gestational age, and hyperemesis gravidarum. In this review, we discuss the reported association between individual GCF biomarkers and common pregnancy complications. Future research is required to provide more solid evidence of the predictive value of those biomarkers in estimating women's risk for each disorder.

The peak of the COVID-19 pandemic led to decreased maternal and child health care engagement, especially among marginalized populations. Existing disparities in prenatal care access and quality faced by pregnant immigrant people are likely to be amplified by the pandemic.

We conducted a study with direct service providers (DSPs) at community-based organizations (CBOs) serving pregnant immigrant families in the Philadelphia region. Semistructured interviews addressed barriers and facilitators to prenatal health care access and engagement among immigrant families both before and then after the onset of the pandemic in March 2020. Additional questions elicited context about the demographics of service populations, organizational connectedness to health care providers, and pandemic-related operational changes.

Between June and November 2021, 10 interviews were conducted in English and Spanish with DSPs at 5 CBOs. Primary themes included diminished access and quality of care received due to decreased language accessibility, increased restrictions around support persons, shifts to telemedicine, and changes to appointment scheduling. Additional themes included heightened hesitancy engaging with services due to documentation status, confusion around legal rights, financial strain, and health insurance status. Interviewees provided suggestions for improving service access during and postpandemic for immigrant pregnant people, including implementation of culturally responsive group prenatal care, institutional policies to improve understanding of legal rights, and increased financial supports.

Understanding emergent and exacerbated barriers to prenatal care access and quality during the COVID-19 pandemic provides context for how to improve health equity for immigrant pregnant people through public health and health care policies as the pandemic continues, and once it has subsided.

Background: Pregnancy, also known as the "gestation period" which lasts for 37-40 weeks, has been marked as the period of "physiological stress" in a woman's life. A wide range of symptoms, from nausea to ectopic pregnancy, are usually aligned with risk factors like abortion, miscarriage, stillbirth, etc. An estimated total of 15% of total pregnant women face serious complications requiring urgent attention for safe pregnancy survival. Over the past decades, several changes in the environment and nutrition habits have increased the possibility of unfavourable changes during the gestation phase. The diagnostic factors, management and nutritional interventions are targeted and more emphasis has been laid on modifying or managing the nutritional factors in this physiologically stressed phase. Aims: This review focuses on dietary modifications and nutritional interventions for the treatment of complications of pregnancy. Nutritional management has been identified to be one of the primary necessities in addition to drug therapy. It is important to set a healthy diet pattern throughout the gestation phase or even before by incorporating key nutrients into the maternal diet. Methods: The published literature from various databases including PubMed, Google Scholar and ScienceDirect were used to establish the fact of management and treatment of complications of pregnancy. Results: The recommendations of dietary supplements have underlined the concept behind the eradication of maternal deficiencies and improving metabolic profiles. Conclusion: Therefore, the present review summarises the dietary recommendations to combat pregnancy-related complications which are necessary in order to prevent and manage the same.

As reported, hypertension (HTN) plays a leading role in explaining mortality worldwide, but it still has many confounding factors. This study explored whether the number of parity and age matters for HTN among couples from the Tehran Lipid and Glucose Study (TLGS).

This study was conducted on 2851 couples from TLGS. All the variables were collected based on the standard protocol. The participants were categorized into four and five categories according to the number of parity (childless, one, two, three, or more parities) and age (18-30y, 30-40y, 40-50y, 50-60y, and 60-70y), respectively. Spline regression models via log link function for the binary outcome and linear link function for continuous outcomes were applied to evaluate the effect of interaction term age and parity categories on the desired outcome.

Among the total of 2851 pairs, 2.3% had no child, 9.5% had 1 child, 38.4% had 2 children, and 49.8% had ≥ 3 children. The adjusted risk (95% CI) of HTN in females aged 40-50y with 1 child, 2 and ≥ 3 children compared to no child were 1.14(1.04, 1.26), 1.05(1.01, 1.10), 1.12(1.07, 1.17), respectively (p < 0.05). Moreover, in those aged 50-60y with 2 and ≥ 3 children, the risk of HTN significantly increased by 4%. In females aged 60-70y with ≥ 3 children compared to those without children, the risk of HTN increased by 2%. For males aged 30-40y with 2 children compared to the no child group, the adjusted risk of HTN increased by 17%, while for those with ≥ 3 children in the same age group, this risk significantly decreased by 13%. Moreover, in males aged 30-40y with 2 children, risk ratio of HTN increased by 17%, but in males with ≥ 3 children, it decreased by 13% and in those in the same groups but aged 40-50y the risk increased by 6% and 11%, respectively.

Our findings suggest that gender, childlessness, having one child, and multi-parity had different impacts on HTN. Further research is needed to confirm our findings.

Women with one lifetime singleton pregnancy have increased risk of cardiovascular disease (CVD) mortality compared with women who continue reproduction particularly if the pregnancy had complications. Women with twins have higher risk of pregnancy complications, but CVD mortality risk in women with twin pregnancies has not been fully described.

We estimated risk of long-term CVD mortality in women with naturally conceived twins compared to women with singleton pregnancies, accounting for lifetime number of pregnancies and pregnancy complications.

Using linked data from the Medical Birth Registry of Norway and the Norwegian Cause of Death Registry, we identified 974,892 women with first pregnancy registered between 1967 and 2013, followed to 2020. Adjusted hazard ratios (aHR) with 95% confidence intervals (CI) for maternal CVD mortality were estimated by Cox regression for various reproductive history (exposure categories): (1) Only one twin pregnancy, (2) Only one singleton pregnancy, (3) Only two singleton pregnancies, (4) A first twin pregnancy and continued reproduction, (5) A first singleton pregnancy and twins in later reproduction and (6) Three singleton pregnancies (the referent group). Exposure categories were also stratified by pregnancy complications (pre-eclampsia, preterm delivery or perinatal loss).

Women with one lifetime pregnancy, twin or singleton, had increased risk of CVD mortality (adjusted hazard [HR] 1.72, 95% confidence interval [CI] 1.21, 2.43 and aHR 1.92, 95% CI 1.78, 2.07, respectively), compared with the referent of three singleton pregnancies. The hazard ratios for CVD mortality among women with one lifetime pregnancy with any complication were 2.36 (95% CI 1.49, 3.71) and 3.56 (95% CI 3.12, 4.06) for twins and singletons, respectively.

Women with only one pregnancy, twin or singleton, had increased long-term CVD mortality, however highest in women with singletons. In addition, twin mothers who continued reproduction had similar CVD mortality compared to women with three singleton pregnancies.

Gestational diabetes mellitus (GDM) is a metabolic complication that affects millions of pregnant women in the world. Placental tissue function is endangered by hyperglycemia during GDM, which is correlated to increased incidences of pregnancy complications. Recently we showed that due to a significant decrease in mitochondrial fusion, mitochondrial dynamics equilibrium is altered in placental tissues from GDM patients. Evidence for the role of reduced mitochondrial fusion in the disruption of mitochondrial function in placental cells is limited.

Here we show that chemical inhibition of mitochondrial fission in cultured placental trophoblast cells leads to an increase in mitochondrial fusion and improves the physiological state of these cells and hence, their capacity to cope in a hyperglycemic environment. Specifically, mitochondrial fission inhibition led to a reduction in reactive oxygen species (ROS) generation, mitochondrial unfolded protein marker expressions, and mitochondrial depolarization. It supported the increase in mitochondrial antioxidant enzyme expressions as well. Mitochondrial fission inhibition also increases the placental cell insulin sensitivity during hyperglycemia.

Our results suggest that mitochondrial fusion/fission equilibrium is critical for placental cell function and signify the therapeutic potential of small molecule inhibitors of fission during GDM.

With good medical care, most pregnancy complications like pre-eclampsia, gestational diabetes, etc resolve after childbirth. However, pregnancy complications are known to be associated with an increased risk of new long-term health conditions for women later in life, such as cardiovascular disease. These umbrella reviews aim to summarise systematic reviews evaluating the association between pregnancy complications and five groups of long-term health conditions: autoimmune conditions, cancers, functional disorders, mental health conditions and metabolic health conditions (diabetes and hypertension).

We will conduct searches in Medline, Embase and the Cochrane database of systematic reviews without any language restrictions. We will include systematic reviews with or without meta-analyses that studied the association between pregnancy complications and the future risk of the five groups of long-term health conditions in women. Pregnancy complications were identified from existing core outcome sets for pregnancy and after consultation with experts. Two reviewers will independently screen the articles. Data will be synthesised with both narrative and quantitative methods. Where a meta-analysis has been carried out, we will report the combined effect size from individual studies. For binary data, pooled ORs with 95% CIs will be presented. For continuous data, we will use the mean difference with 95% CIs. The findings will be presented in forest plots to assess heterogeneity. The methodological quality of the studies will be evaluated with the AMSTAR 2 tool or the Cochrane risk of bias tool. The corrected covered area method will be used to assess the impact of overlap in reviews. The findings will be used to inform the design of prediction models, which will predict the risk of women developing these five group of health conditions following a pregnancy complication.

No ethical approvals required. Findings will be disseminated through publications in peer-reviewed journals and conference presentations.

This study aimed to summarize evidence on the economic outcomes of prenatal and postpartum interventions for the management of gestational diabetes mellitus and hypertensive disorders of pregnancy (HDP), assess the quality of each study, and identify research gaps that may inform future research.

Electronic databases including PubMed/MEDLINE, Embase, the Cochrane Library, and Cochrane Central Register of Controlled Trials were searched from January 1, 2000, to October 1, 2021. Selected studies were included in narrative synthesis and extracted data were presented in narrative and tabular forms. The quality of each study was assessed using the Consolidated Health Economic Evaluation Reporting Standards and Consensus on Health Economic Criteria list.

Among the 22 studies identified through the systematic review, 19 reported favorable cost-effectiveness of the intervention. For prenatal management of HDP, home blood pressure monitoring was found to be cost-effective compared with in-person visits in improving maternal and neonatal outcomes. For postpartum care, regular screening for hypertension or metabolic syndrome followed by subsequent treatment was found to be cost-effective compared with no screening in women with a history of gestational diabetes mellitus or HDP.

Existing economic evaluation studies showed that prenatal home blood pressure monitoring and postpartum screening for hypertension or metabolic syndrome were cost-effective. Nevertheless, limitations in the approach of the current economic evaluations may dampen the quality of the evidence and warrant further investigation.

Complications endangering mother or fetus affect around one in seven pregnant women. Investigation of the genetic susceptibility to such diseases is of high importance for better understanding of the disease biology as well as for prediction of individual risk. In this study, we collected and analyzed GWAS summary statistics from the FinnGen cohort and UK Biobank for 24 pregnancy complications. In FinnGen, we identified 11 loci associated with pregnancy hypertension, excessive vomiting, and gestational diabetes. When UK Biobank and FinnGen data were combined, we discovered six loci reaching genome-wide significance in the meta-analysis. These include rs35954793 in FGF5 (p=6.1×10-9), rs10882398 in PLCE1 (p=8.9×10-9), and rs167479 in RGL3 (p=5.2×10-9) for pregnancy hypertension, rs10830963 in MTNR1B (p=4.5×10-41) and rs36090025 in TCF7L2 (p=3.4×10-15) for gestational diabetes, and rs2963457 in the EBF1 locus (p=6.5×10-9) for preterm birth. In addition to the identified genome-wide associations, we also replicated 14 out of 40 previously reported GWAS markers for pregnancy complications, including four more preeclampsia-related variants. Finally, annotation of the GWAS results identified a causal relationship between gene expression in the cervix and gestational hypertension, as well as both known and previously uncharacterized genetic correlations between pregnancy complications and other traits. These results suggest new prospects for research into the etiology and pathogenesis of pregnancy complications, as well as early risk prediction for these disorders.

Pregnancy complications affect over one quarter of Australian pregnancies, and this group of mothers is vulnerable and more likely to experience adverse cardiometabolic health outcomes in the postpartum period. Metabolic syndrome is common in this population and may be associated with postpartum mental health issues. However, this relationship remains poorly understood. To compare the differences in psychosocial parameters and mental health outcomes between women with metabolic syndrome and women without metabolic syndrome 6 months after a complicated pregnancy.

This study is prospective registry analysis of women attending a postpartum healthy lifestyle clinic 6 months following a complicated pregnancy. Mental health measures included 9-item Patient Health Questionnaire (PHQ-9), 7-item Generalised Anxiety Disorder questionnaire (GAD-7), self-reported diagnosed history of depression, anxiety and/or other psychiatric condition, and current psychotropic medication use.

Women with metabolic syndrome reported significantly more subjective mental health concerns, were more likely to have a history of depression and other psychiatric diagnoses and were more likely prescribed psychotropic medications. However, there were no significant differences in PHQ-9 and GAD-7 scores.

Amongst new mothers who experienced complications of pregnancy, those with metabolic syndrome represent a particularly vulnerable group with regards to psychosocial disadvantage and mental health outcomes. These vulnerabilities may not be apparent when using common standardised cross-sectional mental health screening tools such as PHQ-9 and GAD-7.

Complicated pregnancies by gestational diabetes mellitus (GDM) and hypertensive disorder of pregnancy (HDP) are relatively common worldwide. The evidence is still inconclusive regarding the role of GDM and HDP as spousal risk factor of diabetes (DM) and hypertension (HTN). This study aimed to determine the spousal risk of development of DM and/or HTN in the context of GDM and/or HDP.

This population-based cohort study involved couples who participated in Tehran Lipid and Glucose Study. A total of 3650 pairs of spouses were identified, and among them, 2820 met the inclusion criteria. Included participants, followed up 3-year intervals visits from 1999 to 2018. All pairs underwent standard data collection. GDM and HDP were the main exposure of interest in females, and DM and HTN were the main outcomes in both females and their spouses. Cox proportional hazard regression models were used for both females and their spouses, adjusting for age, consanguinity, waist-to-height ratio, physical activity, smoking, and parity.

Of 2820 females, 558 (19.79 %) had histories of GDM or HDP, and 72 (2.55 %) experienced both. Among females who experienced GDM and HDP, 24 (33 %) and 31 (33 %) developed DM and HTN during the follow-up. The corresponding numbers were 89 (16 %) and 191 (34 %) for those who experienced GDM or HPD, and 274 (13 %) and 623 (28 %) for the non-risk factors group. The incidences of DM were 9 (12 %), 100 (18 %), and 373 (17 %) for males whose spouses experienced both GDM and HDP, either one or none of them, respectively. Among males in these groups, 20 (28 %), 150 (27 %), and 630 (29 %) developed HTN, respectively. Females who never had history of GDM and HDP have 34 % (95 % CI: 21, 45) less hazard of being diabetic than their spouses if they have the same age and waist to hip ratio. In cases with histories of both GDM and HDP, the risk of females increases to 3.05 (95 % CI: 1.43, 6.52) times of their spouses. Also, females who had experienced GDM (HR: 3.51, 95 % CI: 2.23, 5.53), or HDP (HR: 2.80, 95 % CI: 1.72, 4.56) were at higher risk of developing DM compared with females who never had GDM or HDP. We found that females with neither GDM nor HDP were more likely than males to be hypertensive in the future by the hazard ratio of 1.21 (95 % CI: 1.06, 1.39).

Complicated pregnancies by GDM and/or HDP were associated with increased risk of development DM and HTN in later life of females and their spouses. Further studies are required to confirm these results. Preventive care programs should be considered pregnancy complications as couple-based risk factors for subsequent DM and HTN.
