Respiratory function in pregnancy is of special importance since the life of fetus depends primarily upon its oxygen supply. Thus this study was designed to evaluate the Minute ventilation (MV), Maximum Voluntary Ventilation (MVV) & Dyspneic Index (DI) in different trimesters of pregnancy & compare the results with non- pregnant control group. A cross-sectional study was carried out in 200 healthy women in the age range of 19-35 years with 50 subjects each in 1st, 2nd, 3rd trimesters of pregnancy and non-pregnant control group. We recorded respiratory parameters in study and control groups. Statistical analysis was done by ANOVA and Tukey Krammer post Hoc tests. It was observed that there was a significant decrease in MVV and dyspneic index in all trimesters of pregnancy and an insignificant variation in MV when compared to the control group. The changes in pulmonary function are influenced by the mechanical pressure of enlarging gravid uterus, elevating the diaphragm and restricting the movements of lungs thus hampering forceful expiration. The decrease seen in MVV in 1st trimester might be due to bronchoconstriction effect of decreased alveolar Pco2 on the bronchial smooth muscles.

Inappropriate birth weight for gestational age (IBWGA) is linked with obstetric complications like birth asphyxia, hypothermia, and postpartum hemorrhage. This study was aimed at determining the prevalence of IBWGA with factors associated with newborns born at Dessie Referral Hospital, northeast of Ethiopia. We used a retrospective cohort study design and systematic random sampling method to select charts of women giving birth at the hospital from January 2013 to December 2017.

Eisenmenger syndrome (ES) is a rare congenital heart disease (CHD) that occurs in persons with large intracardiac anatomical defects which may go undetected for many years, consequently results in reduced life expectancies and high mortality in the third and fourth decade of life. Pregnancy in patients with CHD and pulmonary arterial hypertension (PAH) is presaged with challenges, and perioperative management of such cases remains a topic of debate. Our case had both, atypical presentation, not diagnosed until her third trimester of third pregnancy and a quick progression to a severe stage with PAH and CorPulmonale.

Introduction/purpose: It is well-documented in the literature that the placenta migrates during pregnancy; however, studies regarding placental cord insertion (PCI) migration are scarce. This longitudinal, prospective study aimed to determine whether PCI migration is a true phenomenon, to assess whether the PCI can change classification during pregnancy and to determine the validity of PCI site documentation including follow-up of abnormal PCI.
Methods: Eighty-three participants who had first, second and third trimester ultrasound examinations at a Western Australian private imaging practice over a 12-month period between November 2021 and November 2022 were recruited.
COVID-19 reinfection in pregnancy: assessment of Severity and pregnancy outcomes in England.

UK Health Security Agency, London, United Kingdom.
Background: Disease severity and pregnancy outcomes following SARS-CoV-2 reinfections in pregnancy are not well understood.
Methods: We linked women aged 18 to 50 years testing positive in the community for COVID-19 between April 2021 and March 2022 to hospital, vaccine and maternal services databases. We compared hospital and intensive care unit (ICU) admission rates following infection and reinfection in pregnant and non-pregnant women, and low birthweight, prematurity and stillbirth in women infected and reinfected during pregnancy.

Background: Antinuclear antibodies (ANA) are important biomarkers for the diagnosis of autoimmune diseases; however, the general population also tests positive at a low frequency, especially in women. Although the effects of various autoimmune diseases on pregnancy outcomes have been studied, the association of ANA with pregnancy outcomes in healthy individuals is unclear. Preterm birth (PTB), a major cause of neonatal death or long-term health problems, is a complex condition with a multifactorial etiology, and the underlying mechanism remains unclear.
