Introduction: The seasonality of human births has been studied globally for over two centuries, revealing diverse patterns across populations shaped by intricate interactions involving both biological and socio-cultural factors. This study offers a thorough examination of national birth data in Greece spanning from 1956 to 2022, aiming to elucidate long-term trends and changes in seasonal birth patterns.

Materials And Methods: Data on live births in Greece were categorized by month based on national registries, and the analysis of birth seasonality was conducted annually.

Decoding Apelin: Its Role in Metabolic Programming, Fetal Growth, and Gestational Complications.

Placental insufficiency and gestational diabetes, which are both serious pregnancy complications, are linked to altered fetal growth, whether restricted or excessive, and result in metabolic dysfunction, hypoxic/oxidative injury, and adverse perinatal outcomes. Although much research has been carried out in this field, the underlying pathogenetic mechanisms have not as yet been fully elucidated. Particularly because of the role it plays in cardiovascular performance, glucose metabolism, inflammation, and oxidative stress, the adipokine apelin was recently shown to be a potential regulator of fetal growth and metabolic programming.

Spontaneous Coronary Artery Dissection in the Late Third Trimester of Pregnancy.

Acute coronary syndrome due to a non-atherosclerotic, non-traumatic, or iatrogenic-induced spontaneous coronary artery dissection (SCAD) is a rare clinical condition that affects mostly young women of reproductive age. In this case, we present a 36-week-pregnant, 35-year-old G2P1 woman, with no previous medical history, who was admitted to our hospital with premature pre-labor contractions. During her hospitalization, she underwent a coronary artery percutaneous angiography revealing SCAD of the three coronary vessels, after an episode of acute-onset chest pain, tachypnea, EKG alterations, cardiac enzyme elevation, and bilateral pleural effusions.

Secular Trends in Preterm Birth Rates: Uncovering the Primary Challenge for Perinatal Medicine in Greece.

This study aims to comprehensively present the time trends of national preterm birth rates (PBRs) in Greece.

Methods: Official national data regarding live births in Greece were acquired from the Hellenic Statistical Authority, and the annual total PBR and rates for gestational age groups were computed per 100 total live births spanning from 1980 to 2022.

Infant, Neonatal, and Post-neonatal Mortality in Greece: A Nationwide Time-Trend Analysis.

Introduction: Infant mortality is a crucial perinatal measure and is also regarded as an important public health indicator. This study aimed to comprehensively present time trends in infant, neonatal, and post-neonatal mortality in Greece.

Methods: The annual infant mortality rate (IMR), the neonatal mortality rate (NMR), and the post-neonatal mortality rate (PNMR) were calculated based on official national data obtained from the Hellenic Statistical Authority, spanning 67 years from 1956 to 2022.

Ectopic pregnancy with full implantation of the gestational sac in the caesarean section scar managed successfully with laparotomy.

Caesarean scar pregnancy represents one of the rarest locations of ectopic pregnancies. It occurs when the blastocyst is implanted in a scar from a previous caesarean section. A dramatic increase of its prevalence has been observed for the last decades, reaching about 21% globally.

The Contribution of Multiple Pregnancies in Stillbirths in Greece: A Time-Trend Analysis.

Introduction Multiple pregnancy is an established risk factor for fetal death. This study aimed to examine the impact of multifetal pregnancies on stillbirth rates (SBRs) in the Greek population. Methods Data on live births and stillbirths by multiplicity were derived from the Hellenic Statistical Authority, covering a 65-year period from 1957 to 2021.

Second Trimester Amniotic Fluid Angiotensinogen Levels Linked to Increased Fetal Birth Weight and Shorter Gestational Age in Term Pregnancies.

Background: Despite the considerable progress made in recent years in fetal assessment, the etiology of fetal growth disturbances is not as yet well understood. In an effort to enhance our knowledge in this area, we investigated the associations of the amniotic fluid angiotensinogen of the renin-angiotensin system with fetal growth abnormalities.

Methods: We collected amniotic fluid samples from 70 pregnant women who underwent amniocentesis during their early second trimester.

Investigating the Association of Assisted Reproduction Techniques and Adverse Perinatal Outcomes.

Background: Infertility affects about 80 million individuals worldwide and 10-15% of couples at reproductive age will seek medical assistance. There is increasing evidence that pregnancies after Assisted Reproduction Techniques (ART) are associated with pre-term birth, low birthweight, congenital defects, and increased mortality rates. The aim of this review is to assess all the published literature and provide an updated review on the effect of assisted conception and perinatal and neonatal outcomes.

Temporal Trends in Stillbirth in Greece: A Longitudinal Population-Based Study.

Introduction: Stillbirths are a major public health issue and a key population health indicator. The aim of this study was to comprehensively investigate and present time trends in stillbirth in Greece.

Methods: Data on all live births and stillbirths were derived from the Hellenic Statistical Authority, covering a 65-year period from 1957 to 2021 and the annual stillbirth rate (SBR) was calculated, defined as the number of stillbirths per 1,000 live births and stillbirths (total births).

Temporal Trends in Multiple Births in Greece: The Evolution of an Epidemic.

Introduction Multiple births constitute the dominant adverse effect of fertility treatments and are associated with increased perinatal risks. The aim of this study was to comprehensively examine and present time trends in multiple births in Greece. Methods Data on live births by multiplicity were derived from the Hellenic Statistical Authority, covering a 65-year period from 1957 to 2021.

Tracing Time Trends of Births in Greece.

Introduction The aim of this study was to comprehensively investigate and present time trends in births in Greece over the last seven decades. Methods Data on live births were derived from the Hellenic Statistical Authority, covering a 72-year period from 1950 to 2021. Trends in the number of births were assessed using joinpoint regression analysis.

Karyotyping and Chromosomal Microarray Analysis in Women Requesting Amniocentesis for Isolated Sonographic Soft Markers or Advanced Maternal Age.

Background: Chromosomal microarray analysis (CMA) has gained acceptance in prenatal diagnosis, gradually replacing the traditional cytogenetic analysis following amniocentesis or chorionic villi sampling due to its higher resolution than traditional cytogenetics.
