Prenatal care is of fundamental importance and must be carried out by a multidisciplinary healthcare team, including dental care, as several changes and complications affecting the oral cavity may occur during pregnancy. This was a cross-sectional study that aimed to analyze the hematological profile of pregnant women with and without periodontal disease (PD). Data were obtained by consulting medical and dental records, which were stratified into two subgroups: pregnant women with PD (n=107) and pregnant women without PD (n=42). Study variables were related to PD, sociodemographic, clinical, and laboratory characteristics. Data were collected from the complete blood count and the following indices were calculated: neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), derived NLR (dNLR), systemic inflammation response index (SIRI), aggregate index of systemic inflammation (AISI), and systemic immune-inflammation index (SII). The mean age in both subgroups was 27 years. Pregnant women with less education had more PD. Mean corpuscular volume was significantly higher in pregnant women with PD, probably a reflection of folate deficiency. White blood cell and lymphocyte counts were significantly higher in pregnant women with periodontitis, possibly reflecting an inflammatory process caused by bacterial invasion of the periodontium with systemic repercussions. This study reinforces the need for a multidisciplinary team, including a dentist, in prenatal care, to lower the risk of complications for the mother and child.

Pain management in pregnant and postpartum people with an opioid use disorder requires a balance among the risks associated with opioid tolerance, including withdrawal or return to opioid use, considerations around the social needs of the maternal-infant dyad, and the provision of adequate pain relief for the birth episode that is often characterized as the worst pain a person will experience in their lifetime. This multidisciplinary consensus statement from the Society for Obstetric Anesthesia and Perinatology, the Society for Maternal-Fetal Medicine, and the American Society of Regional Anesthesia and Pain Medicine provides a framework for pain management in obstetrical patients with opioid use disorder. The purpose of this consensus statement is to provide practical and evidence-based recommendations and is targeted to healthcare providers in obstetrics and anesthesiology.

Objectives: Iron deficiency anaemia and inadequate compliance with iron-folic acid (IFA) supplementation among pregnant and postpartum women pose substantial public health challenges in Nepal. Hence, this study aimed to determine IFA compliance and identify associated factors among postpartum mothers in Bharatpur Metropolitan City, Chitwan, Nepal.

Design: An analytical cross-sectional design was employed.

The advent of automated insulin delivery (AID) systems in 2020 marked a disruptive event in managing type 1 diabetes, benefiting children and adults alike. By 2024, advances in real-world data and research motivated an update to the French consensus on AID systems to expand accessibility, refine guidelines, and optimize patient follow-up. AID systems have consistently improved glycemic control by reducing HbA1c, increasing time-in-range (TIR), and minimizing hypoglycemia, with significant benefits even for specific populations such as individuals with poor glycemic control, brittle diabetes, children, very young children, pregnant women, those with insulin resistance or gastroparesis, or after bariatric surgery.

Objectives: The current study focuses on how abortion access affects people who are pregnant, have chronic kidney disease (CKD), and desire an abortion. From the perspective of the pregnant patient, we will examine the outcomes and costs associated with providing or refusing in-state access to abortion for this population.

Study Design: A decision-analytic model was built to compare the outcomes and costs associated with providing abortions in-state compared to those associated with a complete statewide abortion ban.

Long COVID-19 in pregnancy: increased risk but modest incidence following mild Omicron infection in a boosted obstetric cohort during endemicity.

Background: Significant heterogeneity has been reported in estimates of long-term sequelae following SARS-CoV-2 infection in pregnant women, and most studies were conducted pre-Omicron and pre-dated vaccination rollout. Less severe COVID-19 attributed to milder Omicron may potentially attenuate risk of post-COVID-19 sequelae.

Objective: We sought to examine long-term risk of new-incident multi-systemic sequelae following SARS-CoV-2 Delta/Omicron infection in a population-based cohort of pregnant women, contrasted against a)test-negatives; b)infected non-pregnant women of childbearing age.
