Diabetes During Pregnancy: Surveillance, Preconception Care, and Postpartum Care

Screening and management of major endocrinopathies during pregnancy: an update

Endocrinopathies during pregnancy constitute a challenging issue, being prevalent and requiring appropriate management to avoid maternal and fetal complications. This review aims to summarize and present major endocrine problems during pregnancy, the appropriate screening, maternal monitoring and management, fetal monitoring, and follow-up. Glucose metabolism, thyroid function, as well as calcium and vitamin D metabolism are the main endocrine domains that should be screened and monitored during pregnancy. Gestational diabetes mellitus (GDM) is the most prevalent endocrine disease during pregnancy, followed by thyroid disorders. Specific recommendations are provided for the optimal clinical care of pregnant women and their offspring for GDM, thyroid disorders, and calcium and vitamin D disorders.

Racial disparity in gestational diabetes mellitus and the association with sleep-disordered breathing and smoking cigarettes: a cross-sectional study

BACKGROUND

Gestational diabetes mellitus (GDM) prevalence has risen in the U.S. and worldwide over the past decade. Minority groups, especially Asian and Hispanic women, are often disproportionately affected by GDM. Identifying modifiable risk factors such as sleep-disordered breathing and smoking and their interaction with race/ethnicity could play a pivotal role in preventing GDM.

METHODS

Data from the 2017-2018 National Health and Nutrition Examination Surveys (NHANES) were used to run a survey-weighted multivariable logistic regression assessing the association between sleep-disordered breathing and smoking with GDM among women aged 15-60 (n = 1326). The interaction term of the two predictors and race/ethnicity was introduced to the model to assess the interaction effect. The analyses were adjusted for age, marital status, education level, and BMI.

RESULTS

Approximately 13% of the participants reported having GDM. The lowest prevalence was observed among Non-Hispanic Blacks (7.8%) and the highest was among Other (15.5%). Sleep-disordered breathing was significantly associated with GDM (OR = 1.69, 95% CI 1.05, 2.73). No statistically significant association was observed between smoking and GDM (OR = 1.03, 95% CI 0.47, 2.27), and neither was the association between race/ethnicity and GDM. Furthermore, none of the interaction effects were statistically significant.

CONCLUSION

Preventive strategies targeting GDM should focus on improving modifiable risk factors, such as sleep-disordered breathing. It is important to screen women with sleep-disordered breathing and monitor their blood sugar before becoming pregnant to prevent the development of GDM. Future studies are recommended to understand the lower prevalence of GDM among Black women and the higher prevalence among "Other" race group which mostly includes Asian women.

Mortality Rates Among U.S. Women of Reproductive Age, 1999-2019

INTRODUCTION

High and increasing levels of pregnancy-related mortality and morbidity in the U.S. indicate that the underlying health status of reproductive-aged women may be far from optimal, yet few studies have examined mortality trends and disparities exclusively among this population.

METHODS

All-cause and cause-specific mortality data for 1999-2019 were obtained from the Centers for Disease Control and Prevention WONDER Underlying Cause of Death database. Levels and trends in mortality between 1999 and 2019 for women aged 15-44 years stratified by age, race/ethnicity, and state were examined. Given the urgent need to address pregnancy-related health disparities, the correlation between all-cause and pregnancy-related mortality rates across states for the years 2015-2019 was also examined.

RESULTS

Age-adjusted, all-cause mortality rates among women aged 15-44 years improved between 2003 and 2011 but worsened between 2011 and 2019. The recent increase in mortality among this age group was not driven solely by increases in external causes of death. Patterns differed by age, race/ethnicity, and geography, with non-Hispanic American Indian and Alaskan Native women having 2.3 and non-Hispanic Black women having 1.4 times the risk of all-cause mortality in 2019 compared with that of non-Hispanic White women. Age-adjusted all-cause mortality rates and pregnancy-related mortality rates were strongly correlated at the state level (r=0.75).

CONCLUSIONS

Increasing mortality among reproductive-aged women has substantial implications for maternal, women's, and children's health. Given the high correlation between pregnancy-related mortality and all-cause mortality at the state level, addressing the structural factors that shape mortality risks may have the greatest likelihood of improving women's health outcomes across the life course.

Impact of Maternal-Fetal Environment on Mortality in Children With Single Ventricle Heart Disease

BACKGROUND

Children with single ventricle heart disease have significant morbidity and mortality. The maternal–fetal environment (MFE) may adversely impact outcomes after neonatal cardiac surgery. We hypothesized that impaired MFE would be associated with an increased risk of death after stage 1 Norwood reconstruction.

METHODS AND RESULTS

We performed a retrospective cohort study of children with hypoplastic left heart syndrome (and anatomic variants) who underwent stage 1 Norwood reconstruction between 2008 and 2018. Impaired MFE was defined as maternal gestational hypertension, preeclampsia, gestational diabetes, and/or smoking during pregnancy. Cox proportional hazards regression models were used to investigate the association between impaired MFE and death while adjusting for confounders. Hospital length of stay was assessed with the competing risk of in‐hospital death. In 273 children, the median age at stage 1 Norwood reconstruction was 4 days (interquartile range [IQR], 3–6 days). A total of 72 children (26%) were exposed to an impaired MFE; they had more preterm births (18% versus 7%) and a greater percentage with low birth weights <2.5 kg (18% versus 4%) than those without impaired MFE. Impaired MFE was associated with a higher risk of death (hazard ratio [HR], 6.05; 95% CI, 3.59–10.21; P<0.001) after adjusting for age at surgery, Hispanic ethnicity, genetic syndrome, cardiac diagnosis, surgeon, and birth era. Children with impaired MFE had almost double the risk of prolonged hospital stay (HR, 1.95; 95% CI, 1.41–2.70; P<0.001).

CONCLUSIONS

Children exposed to an impaired MFE had a higher risk of death following stage 1 Norwood reconstruction. Prenatal exposures are potentially modifiable factors that can be targeted to improve outcomes after pediatric cardiac surgery.

Delayed maturation of P2 flash visual evoked potential (VEP) latency in newborns of gestational diabetic mothers

BACKGROUND

The prevalence of gestational diabetes mellitus (GDM) has rapidly increased, yet few prior studies have investigated parameters of early brain development in infants born to gestational diabetic mothers. The present study assessed visual evoked potentials (VEPs) in healthy infants born to gestational diabetic mothers and matched controls.

METHODS

After exclusions, in this prospective study we examined VEPs in 73 neonates between 37 weeks and 41 weeks gestation at birth (n = 37 infants of gestational diabetic mothers). Stroboscopic flashes were presented through closed eyelids during passive electroencephalography (EEG) recording to derive VEP waveforms during natural sleep.

RESULTS

There was a statistically significant moderate correlation between gestational age at birth and P2 latency of the flash VEP where P2 latency significantly decreased with increasing gestational age (Pearson's R(73) = -0.32, p < .01). There was also a significant moderate correlation between postnatal age (hours of life) and P2 latency of the flash VEP where P2 latency significantly decreased with increasing postnatal age (Pearson's R(73) = -0.23, p < .05). When controlling for gestational age at birth, postnatal age, and sex, there was a significant effect of group (GDM-exposed vs. control) on P2 latency of the flash VEP (p < .05). Infants of gestational diabetic mothers had a significantly longer P2 latency (M: 215.29 ± SD: 2.58 ms) than controls (M: 206.41 ± SD: 2.62 ms).

CONCLUSION

Our findings suggest P2 flash VEP latency is a potential measure of cortical maturation and marker of immature development in infants of gestational diabetic mothers.

Racial and Ethnic Disparities in Health Care and Health Outcomes for Pregnant Women With Diabetes

This article summarizes the current literature on racial and ethnic differences among women with diabetes in pregnancy. The PubMed, Scopus, CINAHL, and Embase databases were searched for original qualitative or quantitative studies published in English from January 1, 2009, to May 31, 2020. Consensus statements were excluded. Results of this synthesis indicate that racial and ethnic differences exist among pregnant women with diabetes, including social determinants of health, disparities in maternity care and perinatal care, and maternal and neonatal health outcomes. Health care providers should implement tailored interventions that specifically target racial and ethnic disparities in maternal and neonatal health to promote health equity in pregnant women with diabetes and their offspring, including later in life.

Use of contraception before and after a diabetes diagnosis: An observational matched cohort study

AIMS

To determine how a diabetes diagnosis affects contraception use.

METHODS

This retrospective cohort study used private insurance data from non-pregnant women aged 15-49 years, 2000-2014. We identified women with a new diabetes diagnosis and a control group without diabetes, matched on important potential confounders. We compared rates of prescription or procedural contraception use in the two groups before and after an index date (diabetes diagnosis and outpatient visit, respectively), yielding difference-in-differences estimates of the effect of a diabetes diagnosis on contraception use.

RESULTS

We identified 75,355 women with a new diabetes diagnosis and 7.5 million women without a diabetes diagnosis. Overall rates of contraception use did not increase in the year after diagnosis (absolute difference-in-difference: 0.4% [99.9% CI, -2.1% to 2.9%]; p < 0.001). In method-specific analyses, there was a decline in estrogen-containing and injectable contraceptives in the year after diagnosis (absolute difference-in-difference: -2.2% [-4.0% to -0.4%] and -0.8% [-1.5% to -0.1%], respectively; p < 0.001); no corresponding increase was noted for intrauterine contraception or subdermal implants.

CONCLUSIONS

Women with diabetes are less likely to use contraception after their diabetes diagnosis. Efforts are needed to ensure that women with diabetes receive the counseling and clinical services needed to carefully plan their pregnancies.

Knowledge of preconception care and its association with family planning utilization among women in Ethiopia: meta-analysis

Preconception care (PCC) increases the chance of couple's being healthy and having a healthier baby. It is an important strategy to prevent maternal and perinatal complications. The level of knowledge on preconception care increases its uptake. It is also considered as an input for further intervention of reduction in maternal and neonatal mortality enabling progress towards sustainable development goals (SDGs). Therefore, this systematic review and meta-analysis aimed to estimate the pooled knowledge level of PCC and its association with family planning usage among women in Ethiopia. All observational studies regardless of publication status were retrieved. Important search terms were used to search articles in Google scholar, African Journals Online, CINHAL, HINARI, Science Direct, Cochrane Library, EMBASE, and PubMed/Medline. Independent critical appraisal of retrieved studies was done using the Newcastle-Ottawa assessment checklist. The meta-analysis was conducted using STATA version 14 software. The I² statistics were used to test heterogeneity, whereas publication bias was assessed by Begg's and Egger's tests. The results of the meta-analysis were explained in the Odds ratio (OR) with a 95% confidence interval (CI) and presented using forest plots. A total of seven articles were included in the current systematic review and meta-analysis. Based on the data retrieved from the articles, 35.7% of women in Ethiopia had good knowledge about preconception care. The subgroup analysis based on region revealed the lowest (22.34%) and highest (45.06%) percentage of good knowledge on preconception care among women who were living in Amhara and Oromia regions, respectively. Moreover, women who utilized family planning services were three and more times (OR 3.65 (95% CI 2.11, 6.31)) more likely to have a good level of knowledge about preconception care. One-third of Ethiopian women had good knowledge about preconception care. Family planning utilization had a positive impact on women's knowledge of preconception care.

Adverse Birth Outcomes Among Women of Advanced Maternal Age With and Without Health Conditions in Maryland

BACKGROUND

Advanced maternal age (AMA) has been linked to both higher risk of adverse birth outcomes and higher levels of comorbidities. It is unclear if adverse outcomes are higher for older healthy women. This study examined the association between AMA and adverse birth outcomes among women with and without preexisting and pregnancy-related health conditions.

METHODS

Analysis of data for 14,933 singleton births between 2004 and 2015 from the population-based Maryland Pregnancy Risk Assessment Monitoring System was conducted, comparing women aged 20-34 years and 35 years and older. Multivariable logistic regression estimated the difference in odds of preterm birth (PTB) and low birthweight (LBW) by age group among women with and without health conditions. The analysis of women without health conditions was stratified by parity.

RESULTS

Among women without health conditions, AMA was associated with higher odds of PTB regardless of birthweight, LBW regardless of term, LBW term births, and LBW PTBs; stratified analysis showed higher risk of these outcomes among both older primiparas and multiparas. Compared with younger women with hypertensive disorders, older women with similar health conditions had higher odds of PTB regardless of birthweight. Older women with asthma had higher odds of LBW term births.

CONCLUSIONS

AMA is associated with adverse birth outcomes among women with and without health conditions compared with younger women with similar health status. Improved screening and management of health conditions during pregnancy is needed for older women, regardless of parity.

A Novel Model for a Free Clinic for Prenatal and Infant Care in Detroit

PURPOSE

Detroit experiences the highest preterm birth rate and some of the worst birth outcomes in the country. Women and children have extremely high levels of poverty and face numerous barriers to care including lack of trust and racial disparities in care and concrete barriers such as limited transportation and childcare, work hour conflicts, and lack of insurance.

DESCRIPTION

We report on a unique model of patient care focused on providing patient-centered care and building trusting relationships. This model is encompassed in a new free, volunteer-run, faith-based clinic which offers prenatal, postpartum, and infant care.

ASSESSMENT

In the first 2 years of operation, demand for services rose rapidly and there were stellar clinical outcomes, despite the fact that Luke patients are among the medically and socially highest risk populations in the nation.

CONCLUSION

While marginalized populations have worse birth outcomes and far more infant deaths, making care accessible and responsive to patient needs while focusing on building patient relationships is an important strategy to improve outcomes.

Beyond Birth Control: Noncontraceptive Benefits of Hormonal Methods and Their Key Role in the General Medical Care of Women

Contraceptives that contain estrogen and/or progestins are used by millions of women around the world to prevent pregnancy. Owing to their unique physiological mechanism of action, many of these medications can also be used to prevent cancer and treat multiple general medical conditions that are common in women. We performed a comprehensive literature search. This article will describe the specific mechanisms of action and summarize the available data documenting how hormonal contraceptives can prevent ovarian and uterine cancer and be used to treat women with a variety of gynecological and nongynecological conditions such as endometriosis, uterine fibroids, heavy menstrual bleeding, polycystic ovary syndrome, acne, and migraines. Contraceptive methods containing estrogen and progestin can be used for a wide variety of medical issues in women.
