Importance: Diabetes mellitus is one of the most common complications in pregnancy with adverse maternal and neonatal risks proportional to the degree of suboptimal glycemic control, which is not well defined. Literature guiding providers in identifying and managing patients at highest risk of complications from diabetes is lacking.

Objective: This article reviews the definition, epidemiology, and pathophysiology of suboptimal control of diabetes in pregnancy, including "diabetic fetopathy"; explores proposed methods of risk stratification for patients with diabetes; outlines existing antepartum management and delivery timing guidelines; and guides direction for future research.

As many as 1 in 3 patients with gestational diabetes mellitus have impaired glucose metabolism when screened postpartum. These patients have a 40% to 70% lifetime risk of progression to type 2 diabetes mellitus, but progression can be delayed or prevented by lifestyle interventions or medication. The American College of Obstetricians and Gynecologists and the American Diabetes Association recommend a glucose tolerance test at 4 to 12 weeks postpartum for all patients with gestational diabetes mellitus.

The frequency of telemedicine encounters has increased dramatically in recent years. This review summarizes the literature regarding the safety and quality of telemedicine for pregnancy-related services, including prenatal care, postpartum care, diabetes mellitus management, medication abortion, lactation support, hypertension management, genetic counseling, ultrasound examination, contraception, and mental health services. For many of these, telemedicine has several potential or proven benefits, including expanded patient access, improved patient satisfaction, decreased disparities in care delivery, and health outcomes at least comparable to those of traditional in-person encounters.

Rising maternal morbidity and mortality rates, widening healthcare disparities, and increasing focus on cardiometabolic risk modification in at-risk patients have together catalyzed a shift in the postpartum care paradigm. What was once a single office visit in the 6 weeks after delivery is now being reimagined as a continuum of care that transitions patients from pregnancy to lifelong health optimization. However, this shift in postpartum care also comes with increased visit complexity and additional provider burden, particularly when patients have had significant pregnancy complications or have chronic diseases.

Hypertensive disorders of pregnancy are a leading cause of maternal morbidity and mortality. Because postpartum exacerbation of severe hypertension is common, the American College of Obstetricians and Gynecologists recommends that patients with severe hypertension during the childbirth hospitalization be seen within 72 hours after discharge. In this statement, the Society for Maternal-Fetal Medicine proposes a uniform metric reflecting the rate of timely postpartum follow-up of patients with severe hypertension.

Background: Given the significant morbidity and mortality of maternal sepsis, early identification is key to improve outcomes. This study aims to evaluate the performance characteristics of the systemic inflammatory response syndrome (SIRS), quick Sequential [Sepsis-related] Organ Failure Assessment (qSOFA), and maternal early warning (MEW) criteria for identifying cases of impending sepsis in parturients. The secondary objective of this study is to identify etiologies and risk factors for maternal sepsis and to assess timing of antibiotics in patients diagnosed with sepsis.

Grebe dysplasia is a rare skeletal dysplasia characterized by severe acromesomelic shortening of the long bones in a proximal to distal gradient of severity, with bones of the hands and feet more severely affected than those of the forearms and legs, which in turn are more severely affected than the humeri and femora. In addition, the bones of the lower extremities tend to be more severely affected than the bones of the upper extremities. Despite the severe skeletal deformities, the condition is not lethal and surviving individuals can have normal intelligence.

Objective: Our primary objective was to apply metabolomic pathway analysis of first trimester maternal serum to provide an insight into the pathogenesis of late-onset preeclampsia (late-PE) and thereby identify plausible therapeutic targets for PE.

Methods: NMR-based metabolomics analysis was performed on 29 cases of late-PE and 55 unaffected controls. In order to achieve sufficient statistical power to perform the pathway analysis, these cases were combined with a group of previously analyzed specimens, 30 late-PE cases and 60 unaffected controls.

Protein kinase C epsilon (PKCε), a Ca(2+)-independent phospholipid-dependent serine/threonine kinase, is among the six PKC isoforms (α, δ, ε, η, μ, ζ) expressed in both mouse and human skin. Epidermal PKCε level dictates the susceptibility of PKCε transgenic (TG) mice to the development of cutaneous squamous cell carcinomas (SCC) elicited either by repeated exposure to ultraviolet radiation (UVR) or by using the DMBA initiation-TPA (12-O-tetradecanoylphorbol-13-acetate) tumor promotion protocol (Wheeler,D.L.

Objective: We sought to perform validation studies of previously published and newly derived first-trimester metabolomic algorithms for prediction of early preeclampsia (PE).

Study Design: Nuclear magnetic resonance-based metabolomic analysis was performed on first-trimester serum in 50 women who subsequently developed early PE and in 108 first-trimester controls. Random stratification and allocation was used to divide cases into a discovery group (30 early PE and 65 controls) for generation of the biomarker model(s) and a validation group (20 early PE and 43 controls) to ensure an unbiased assessment of the predictive algorithms.

Aims: Fetuses with gastroschisis are at increased risk of intrauterine growth restriction (IUGR). However, there is a tendency for underestimation of fetal abdominal circumference and hence fetal weight, leading to overdiagnosis of IUGR. Our objective was to evaluate the accuracy of ultrasound for the prediction of being small for gestational age (SGA) at birth in these cases.
