Previous studies have shown that low birth weight (LBW) is a risk factor for renal impairment in adult life. The effects of LBW and renal function were studied by using twins, which allows distinguishing among fetoplacental, maternal, and genetic influences. Perinatal data were obtained at birth, and absolute creatinine clearance ...

Olfactory dysfunction has been proposed to be a sign that may precede the motor features of Parkinson's disease (PD). To determine whether smell identification deficits predict subsequent PD, we studied smell identification ability using the University of Pennsylvania Smell Identification Test (UPSIT) in 62 members of male twin pairs discordant ...

We assessed the outcome of thirteen neonates (five singletons and eight first twins) born after umbilical cord prolapse (UCP) following preterm premature rupture of membranes (PPROM) between 24 and 34 weeks of gestation. The median gestational age at PPROM was 29 weeks + 2 days. The median interval from the ...

Neisseria lactamica, a harmless human commensal found predominantly in the upper respiratory tracts of infants, is closely related to Neisseria meningitidis, a pathogen of global significance. Colonization with N. lactamica may be responsible for the increase in immunity to meningococcal disease that occurs during childhood, when rates of meningococcal carriage ...

The spiny mouse is relatively mature at birth. We hypothesized that like other organs, the kidney may be more developed in the spiny mouse at birth, than in other rodents. If nephrogenesis is complete before birth, the spiny mouse may provide an excellent model with which to study the effects ...

We hypothesized that cord blood erythropoietin (EPO), a marker of fetal hypoxia, relates to gestational factors and not solely those associated with delivery. We investigated the association between birth weight SD score (SDS) and cord blood EPO in 290 twins (145 pairs), assessing the influence of gestational versus perinatal factors ...

Despite the continuous breeding that has been conducted with asparagus (Asparagus officinalis L.) since the beginning of the last century, there is little information on parameters for predicting direct and indirect selection response. Yield traits for blanched asparagus production were studied along a two-year period in a half-sib family population ...

Several systematic reviews have been published recently on birth outcomes of infants conceived through assisted reproductive technologies (ART), compared with infants conceived spontaneously. These outcomes include perinatal mortality, preterm birth, low birthweight and birth defects. Methodological limitations of many of the individual studies (including small sample size, potential for bias ...

This paper introduces a method to simultaneously minimize the leaf travel distance and the tongue-and-groove effect for IMRT leaf sequences to be delivered in segmental mode. The basic idea is to add a large enough number of openings through cutting or splitting existing openings for those leaf pairs with openings ...

We analyze the association between the rates of multiple maternities. Correlation analysis is suitable if there are at least monotonic relationships between the variables. A decreasing tendency can be observed in the rates of multiple maternities in Sweden and in its 25 counties for the period 1751-1960 and the effect ...

Barrett J F R - - 2004
The ever-increasing incidence of twin pregnancies world wide, together with the increasing trend to caesarean delivery, has resulted in intense scrutiny of the most appropriate method of twin delivery. The term twin has an increased risk of twin mortality compared to term singletons and this might be a result of ...

The current epidemic of triplets, a result of the widespread use of assisted reproduction, started less than two decades ago. Its full impact has been appreciated only recently. Triplets are disadvantaged from every perinatal perspective compared to twins--preterm birth, low birth weight, morbidity and mortality--because the human uterus probably is ...

OBJECTIVE: Delaying delivery of the remaining fetus(es) in a multifetal pregnancy is feasible in some cases. However, the impact of this procedure on infant survival is unclear. STUDY DESIGN: We used the US 1995-1998 Matched Multiple Birth File. We identified 200 twin pregnancies in which the first twin was delivered ...
Simmons Rebecca - - 2004
The proportion of multiple births has increased markedly since 1980 in England and Wales. A major contribution to this trend is thought to be the widespread introduction of assisted reproductive technologies. Despite a continuing (but slower) upward trend in twin maternities, analysis of recent data shows that the rate of ...
