OBJECTIVES To evaluate whether genetic factors contribute to the association between low birth weight and increased blood pressure among adolescents. DESIGN Historical cohort study of twin pairs. It was evaluated whether (1) a negative association between birth weight and systolic blood pressure was found in the overall twin sample and (2) whether the intrapair difference in birth weight corr...

BACKGROUND Our aim was to study attitudes towards twins and single embryo transfer (SET) among IVF/ICSI-twin mothers with 3 to 4-year old children. METHODS A national survey was conducted by questionnaire (n = 1769). The study population consisted of IVF/ICSI-twin mothers (n = 266), and the two control groups of IVF/ICSI-singleton mothers (n = 764) and non-IVF/ICSI-twin mothers (n = 739), all...

BACKGROUND Twin pregnancies in low- and middle-income countries (LMICs) pose a high risk to mothers and newborns due to inherent biological risks and scarcity of health resources. We conducted a secondary analysis of the WHO Global Survey dataset to analyze maternal and perinatal outcomes in twin pregnancies and factors associated with perinatal morbidity and mortality in twins. METHODS We ex...

A twin is described who was born with ileal atresia and hydranencephaly, the co-twin having died at about 24 weeks' gestation. If a macerated or autolysed twin is found at birth, the paediatrician should be alerted to the possibility of serious and not immediately obvious defects in the surviving infant.

AIM To assess the accurate establishment of chorionicity, perinatal complications, and outcome of monochorionic twin pregnancies managed in a tertiary referral center in Croatia and compare the findings with data published for other countries. METHODS The retrospective analysis included data on a total of 24 monochorionic twin pregnancies delivered at the Department between January 1998 and M...

Low birth weight (LBW) can have an impact on health outcomes in later life, especially in relation to pre-disposition to metabolic disease. Several studies suggest that LBW resulting from restricted intrauterine growth leaves a footprint on DNA methylation in utero, and this influence likely persists into adulthood. To investigate this further, we performed epigenome-wide association analyses o...

Performance records (birth weight and actual milk yield) on 206 Swedish Red cattle maintained at private organic diary cattle enterprise in Kelkit district of Gümüşhane province, in Turkey, were analyzed through regression tree method to determine the effects of some factors affecting birth weight and actual milk yield. The birth weight of calves averaged as 41.034±4.218 kg. Out of total calves...

STUDY QUESTION Do birthweight (BW) and co-twin sex influence the age at menarche in twins? SUMMARY ANSWER BW, but not co-twin sex, was associated with age at menarche in twins. However, BW was not associated with age at menarche after controlling for genetics and shared rearing environment. WHAT IS KNOWN ALREADY Nutritional deprivation during critical developmental periods can trigger long-...

OBJECTIVE To estimate the maternal puerperal morbidity in elective and emergent cesareans in twins. STUDY DESIGN We evaluated postpartum complications among patients who underwent elective cesarean birth for twin pregnancy. This group was compared to matched singletons and to emergent cesareans in twins. RESULTS During the period September 1994-March 2006 there were 299 (47.4%) elective and...

The rate of caesarean sections in multiple births has grown sharply worldwide. The reason for this may be the results of large retrospective cohort studies from the 1990s, which displayed an increased risk of mortality and morbidity, especially for the second twin, in the case of vaginal births. Multiple monocentric analyses have not been able to confirm this. As a prospective, multi-centre ran...
