Surgical glove perforation in caesarean section and its association with surgical site infections: a prospective cohort study.

Objective: Infectious complications at the surgical site complicates 1-4% of cesarean deliveries. Strict aseptic technique, hand hygiene and the use of sterile surgical gloves are essential to reduce the risk of surgical site contamination. Glove perforations are observed in almost 30% of all procedures and represent an underestimated potential risk factor for postoperative infections.

Perinatal outcomes and predictors of neonatal mortality in preterm premature rupture of membranes: a tertiary center experience.

Background: Preterm premature rupture of membranes (PPROM) is a serious obstetric condition associated with increased maternal, fetal, and neonatal morbidity and mortality. It accounts for approximately one-third of all spontaneous preterm births and is associated with complications such as respiratory distress syndrome (RDS), sepsis, pulmonary hypoplasia, and neonatal mortality. Despite significant advances in prenatal care, proper management, particularly in early gestational age, remains unclear.

Relationship Between Adverse Neonatal Outcomes and Diastolic Deceleration Area on Fetal MCA Doppler in Patients with Late Fetal Growth Restriction.

Objectives: This study aimed to assess the predictive value of the Diastolic Deceleration Area (DDA), a novel Doppler ultrasound parameter, in detecting adverse neonatal outcomes in fetuses with late-onset fetal growth restriction (FGR). While Doppler parameters such as cerebroplacental ratio (CPR), umbilicocerebral ratio (UCR), and cerebralplacentaluterine ratio (CPUR) are commonly used for fetal monitoring, their predictive power varies. Given the importance of cerebral blood flow redistribution in fetal adaptation to hypoxia, we investigated whether DDA could serve as a reliable indicator of fetal distress and adverse perinatal outcomes.

Objectives: This study evaluates the association of novel inflammatory markers and Doppler parameters in late-onset FGR (fetal growth restriction), utilizing a machine-learning approach to enhance predictive accuracy.

Materials And Methods: A retrospective case-control study was conducted at the Department of Perinatology, Ministry of Health Etlik City Hospital, Ankara, from 2023 to 2024.

Evaluation of Anterior and Middle Brain Structures With Cerebrovascular Flow in Fetuses With Fetal Growth Restriction: A Prospective Study.

Objective: To investigate the adaptation of the anterior cerebral artery (ACA) in fetuses with fetal growth restriction (FGR) and assess if forebrain and midbrain structures are affected by vascular adaptations.

A practical new approach to ultrasonographic detection of the fetal situs: Modified Cordes technique.

This study presents the modified Cordes method, a novel ultrasonographic technique that provides a precise and practical evaluation of fetal situs during pregnancy, particularly in the first and early second trimesters. This method entails precisely aligning the probe and hand to obtain a clear image of the fetal thorax in the axial plane. The fundamental procedures involve ascertaining the initial location of the fetal head, rotating the probe, aligning the thorax at the center, and positioning the left hand to clearly identify the fetal situs.
