Obesity is related to maternal periodontitis severity in pregnancy: a cross-sectional study.

Objectives: To evaluate the relationship between obesity and periodontitis staging compared with periodontal healthy or gingivitis in pregnant women.

Materials And Methods: An analytical cross-sectional study was conducted on pregnant women between 11 and 14 weeks of pregnancy. Sociodemographic, clinical, obstetric, and periodontal variables were studied.

A reasoned approach towards administering COVID-19 vaccines to pregnant women.

There are over 50 SARS-CoV-2 candidate vaccines undergoing Phase II and III clinical trials. Several vaccines have been approved by regulatory authorities and rolled out for use in different countries. Due to concerns of potential teratogenicity or adverse effect on maternal physiology, pregnancy has been a specific exclusion criterion for most vaccine trials with only two trials not excluding pregnant women.

Placental biomarkers and angiogenic factors in oral fluids of patients with preeclampsia.

Objectives: The objectives of this study are to explore the feasibility of measuring endothelial and placental biomarkers in saliva and gingival crevicular fluid (GCF) and to determine if patients with preeclampsia (PE) have a different profile of these biomarkers in oral fluids.

Method: A case-control study was conducted, including patients with PE (n = 10) and a control group with normal pregnancies randomly selected (n = 20) admitted at the Sótero del Río Hospital in Santiago, Chile. A complete periodontal and obstetric history that involved the collection of oral fluids was performed at the same gestational age.
