The objective of the present work was the comparative study of the state of the acoustic analayzer in the full-term and premature infants born after multifetal (MP) or singleton (SP) pregnancies with the body weight at birth corresponding to the gestational age (normotrophics) and presenting with intrauterine growth retardation (IUGR). The method of distortion product otoacoustic emissions (DPOAEs) was employed in the study. It has demonstrated that the normotrophic babies born at the gestational age over 34 weeks after singleton pregnancy pass the DPOAEstest significantly more frequently than normotrophics of the same gestational age born after multifetal pregnancy. Moreover, the unilateral impairment of hearing in the full-term infants born after multifetal pregnancy occurs more frequently than in those born after singleton pregnancy.

Impact of Chorionicity in Neurodevelopmental Outcomes in Preterm Twins.

Neonatology Department, Maternidade Bissaya Barreto, Unidade Local de Saúde de Coimbra, Coimbra, PRT.
Introduction Multifetal pregnancies, which account for 2-4% of births worldwide, have increased in recent years. Twin pregnancies carry a higher risk of preterm birth and associated neonatal morbimortality, with monochorionic twins considered at greater risk. This study investigates the influence of chorionicity on neurodevelopmental outcomes in preterm twins.

Article Synopsis
- Vanishing Twin Syndrome (VTS) is when one fetus in a multiple pregnancy disappears, often discovered through ultrasounds, but its genetic causes are not well understood.
- A case study of a 39-year-old woman who conceived twins via IVF showed that one twin's heartbeat stopped at 11 weeks, confirming VTS while the other developed normally.
- Genetic testing revealed that both fetuses were identical twins with a normal genetic make-up, but the vanished twin exhibited a unique genetic pattern, demonstrating the potential for genetic investigation in cases of VTS.
Is Fetal Reduction Necessary in Triplet Pregnancy? Single Tertiary Center Experience.

December 2024
Department of Obstetrics and Gynecology, Necmettin Erbakan University Medical School of Meram, Konya, Turkey.
Objective: This study aims to evaluate the perinatal outcomes of triplet pregnancies reduced from triplets to twins with fetal reduction (FR), followed expectantly without FR, and reduced to triplets from higher-order multiple pregnancies (HOMP) with FR.
Materials And Methods: Multifetal pregnancies followed at the university hospital in the last 8 years were evaluated retrospectively. The study group was composed of three groups.
Placental correlates in categories of preterm births based on gestational age.

Department of Pathology, St. John's Medical College, Bangalore, India, 560076. Electronic address:
Unlabelled: Placental abnormalities can precipitate preterm birth (PTB), a principal contributor to neonatal morbidity and mortality. This study targets understanding placental variations among different gestational age-based categories of PTB.
Methods: A three-year retrospective study conducted a detailed clinicopathological analysis of PTB placentas categorized by gestational age: extremely preterm (EPTB,<28 weeks), very preterm (VPTB, 28 to 31 + 6 weeks), moderate preterm (MPTB, 32 to 33 + 6 weeks), and late preterm (LPTB, 34 to 36 + 6 weeks).
Birth outcomes in mothers with hypertensive disorders and polycystic ovary syndrome: a population-based cohort study.

Study Question: Is polycystic ovary syndrome (PCOS) associated with higher risks of extreme birth size and/or preterm birth in mothers with different hypertension types?
Summary Answer: PCOS was associated with additional risks of preterm birth in mothers with chronic hypertension and in singleton pregnancies of mothers with pre-eclampsia, and with higher risks of offspring born large for gestational age (LGA) in mothers with gestational hypertension.
What Is Known Already: Women with PCOS are more likely to develop gestational hypertension, pre-eclampsia, and chronic hypertension. Although adverse birth outcomes have been frequently reported in mothers with PCOS, such associations in the setting of a hypertensive disorder remain unknown.
