Background: Smoking during pregnancy is associated with higher blood pressure in neonates.
Objective: To analyze whether smoking during pregnancy has an influence on peripheral tissue oxygenation in healthy term neonates within the first days after delivery.
Methods: In a prospective cohort study, 15 healthy term neonates of mothers who had smoked during pregnancy (smoking group) were matched for gestational age, actual weight and postnatal age to 15 healthy term neonates of mothers who had not smoked during pregnancy (non-smoking group). Peripheral oxygenation was measured by near-infrared spectroscopy in combination with the venous occlusion method on the left forearm. Measurements were performed within the first 2 days after delivery. Tissue oxygenation index (TOI), fractional oxygen extraction (FOE), oxygen delivery (DO(2)) and oxygen consumption (VO(2)) were analyzed.
Results: In neonates measured within the first day after delivery, TOI was significantly lower and FOE was significantly higher (63.5 +/- 5.5; 0.37 +/- 0.04) in the smoking group compared to the non-smoking group (69.2 +/- 2.9; 0.30 +/- 0.04). DO(2) tended to be lower and VO(2) tended to be higher in the smoking group. In neonates measured on the second day after delivery, no significant differences were observed between the groups.
Conclusions: Smoking during pregnancy reduced TOI and increased FOE in otherwise healthy neonates on the first day of life with normalization on the second day of life.

Objective: To determine whether chronodisruption is associated with achieving pregnancy.
Design: Pilot prospective cohort study.
Subjects: One hundred eighty-three women desiring pregnancy were recruited from the local community of an academic medical center located in the Midwest and provided sleep information between February 1, 2015, and November 30, 2017.

Smoking has adverse effects on both maternal and fetal health and its incidence varies among different countries. The aim of this study was to identify the prevalence of smoking during pregnancy and to identify factors associated with smoking. This was a retrospective study conducted at the Third Department of Obstetrics and Gynecology, School of Medicine, Faculty of Health Sciences, Aristotle University of Thessaloniki, Greece, during an 11-year period (2013-2023).

Limited evidence links maternal macronutrient intake to gestational diabetes mellitus (GDM) risk. Therefore, we evaluated these intakes both before and during pregnancy, comparing macronutrient data against the European Food and Safety Authorities' (EFSA) Dietary Reference Values (DRVs). Data were prospectively collected from the Greek BORN2020 epidemiologic pregnant cohort, which included 797 pregnant women, of whom 14.

Background/objectives: Inadequate cardiovascular adaptation during pregnancy impairs endothelial function and vascular resistance, contributing to complications such as pre-eclampsia (PE) and gestational hypertension (GH). Neprilysin (NEP), a protease involved in vascular regulation, has been linked to PE, but its role in endothelial function and vascular adaptation remains unclear. This pilot study investigates the associations between soluble neprilysin (sNEP) and markers of vascular and renal function in high-risk pregnancies without PE.

This research investigates the impact of exogenous and endogenous factors on fetal health in pregnant women under the age of 18, with a special focus on the influence of educational level, adherence to vices (smoking and alcohol), comorbidities (diabetes and hypertension), and poor sanitary conditions. The study uses retrospective data collected from a medical institution in the Southeast region of Romania, including a sample of 3639 births during the post-pandemic period (2022-2023). This period was considered to be a reference period for the study because, as a result of measures to combat the spread of COVID-19 disease in the pandemic, there was an increase in the birth rate among patients under 18 years of age.
