Background: Twin low-birth-weight (LBW) neonates are exposed to the increased risk of mortality and morbidity due to poor prognosis. The present study aimed to evaluate the effectiveness of kangaroo mother care (KMC) in the management of twin LBW neonates. Methods: This prospective, observational study was conducted on 150 neonates with the birth weight of

A retrospective study was carried out on a sample consisting of 89,491 deliveries occurred from 1979 through 1998, in the city of São Paulo, SP, Brazil. These deliveries included 935 twin and 26 triplet births. The mean incidence per 1,000 deliveries was estimated at 10.45 for twins (5.34 for dizygotic and 5.11 for monozygotic twins) and 0.29 for triplets. The average maternal age increased sig...

the fecundity in sheep has been much interested for producers due to its economical importance. growth differentiation factor 9 (gdf9) is an autosomal gene with over dominance effect for twosingle nucleotide polymorphisms(snps), which resulted in sterility in homozygote mutant ewes and additive effect for three snps, without showing sterility event. in the present study, dna was extracted from ...

background : twin pregnancies are commonly associated with low birth weight (lbw) infants. most studies focus on growth of lbw compared with normal infants in singleton. however, there has not been any study on twins to com-pare lbw with normal birth weight (nbw) infants as a match control of the same twin. methods : this cohort study was conducted at healthcare centers of kashan, in 2013. twin...

Background: Comparison of obstetric and neonatal outcomes of twin pregnancies conceived by assisted reproduction technology (ART) with those of spontaneously conceived (SC). Materials and Methods: In this prospective cohort study, all dichorionic twin pregnancies following fresh IVF/ intra-cytoplasmic sperm injection (ICSI) or ICSI cycles (n=320) and (SC) (n=170) in nulliparous women in Royan I...

Fetus in fetu is an extremely rare condition embryologically arising in monozygotic diamniotic twins with an incidence of 1:500,000 births. To the best of our knowledge, number of reported cases should not be more than 100 with majority of cases presenting in post natal life with only 5 cases detected prenatally. We are presenting a case diagnosed at 24 weeks of gestation on ultrasound with pre...

OBJECTIVE To evaluate whether a history of preterm birth or small for gestational age (SGA) in a singleton pregnancy is associated with an increased risk of recurrence of the same condition in a subsequent twin pregnancy. METHODS Retrospective cohort study of twin pregnancies delivered in one maternal-fetal medicine practice from 2005 to 2014. Patients with a history of singleton preterm birt...

The quarter of birth of 536 schizophrenic, 1,991 neurotic and 12,085 psychiatrically normal twin pairs from the National Academy of Sciences-National Research Council Twin Registry was compared. When either all twin pairs, or only monozygotic or dizygotic twin pairs, were considered, no significant differences were found in the quarter of birth between the 3 groups. No difference in quarter of ...

In this study we examine the hypothesis that monozygotic (MZ) twins in historical databases are less discordant for birth weight due to negative selection of severely discordant MZ twins. Furthermore, we test the hypothesis that MZ twins are less discordant for birth weight when comparing a volunteer based twin registry with a population based twin registry, due to selective registration. Data ...
