Studies of the fibrinolytic enzyme system in the plasma of mothers and the newborn infants are reported and the results compared. All mothers had elevated levels of fibrinogen in the plasma at the time of delivery. The levels of fibrinogen in the newborn infants fell into a low normal range. Premature infants tended to have slightly lower levels of fibrinogen than term infants, with certain exceptions which are discussed. A direct correlation of values for fibrinogen with the birth weight could not be established. No correlation was observed between fibrinogen levels in mothers and infants, indicating that significant placental transfer of fibrinogen does not occur under normal conditions and that fibrinogen is manufactured by the fetus itself. All mothers had higher levels of free and total profibrinolysin in the plasma than did the infants. The differences were found to be highly significant. The levels of free profibrinolysin in premature infants did not vary as much from those of the term babies, as was the case with total profibrinolysin. The levels of total profibrinolysin show a definite trend upward with increasing birth weight. Inhibitors of the fibrinolytic enzyme system were also significantly higher in mothers than in infants. Premature infants had significantly lower levels than term infants although considerable overlapping in the range was noted. Evidence was obtained that small amounts of an active proteolytic enzyme are present in the euglobulin fraction of the mother at delivery even after the course of a normal labor. No hemorrhagic manifestations were observed, presumably because of the high levels of inhibitor in maternal blood. In contrast, lysis of clots was observed more frequently in samples of cord blood, possibly due to lower levels of inhibitor. Placental transfer of various decomposition products of protein apparently exists as indicated by measurements of trichloracetic acid-soluble products in samples of plasma. A possible relation between the low proteolytic activity of the plasma of premature infants and the high incidence of fatality from hyaline membrane disease in these infants is proposed and discussed.

Unfortunately, premature birth occurs commonly in the United States. Improving the survival of very low-birth-weight (VLBW) infants depends in large part upon understanding the physiologic capabilities of their immature organ systems and providing appropriate support as they mature. Advances in the nutritional support of these infants have contributed to the better outcomes we have come to expect today, even for the smallest infants. In this review, we will discuss the limitations of gastrointestinal function and the unique nutritional requirements of very low-birth-weight infants and describe the current methods of enteral and parenteral nutrition support used to meet these requirements. Developmental Physiology By 24 to 26 weeks of gestation, the fetal gastrointestinal tract is morphologically similar to that of the full-term infant; however, functional development is far from complete. Maturation of gastrointestinal motility, digestion, and absorption continues through much of the first year of life, even in full-term infants, as a result of an interplay between the preprogrammed "biological clock" and environmental influences. The decision to feed the VLBW infant must take into account the developmental limitations as well as the potential for enhancing intestinal maturation at each stage of development (Table 1). Fetal swallowing is evident at the beginning of the second trimester.

ABSTRACT Objective: To compare somatic growth, lung function, and level of physical activity in schoolchildren who had been very-low-birth-weight preterm infants (VLBWPIs) or normal-birth-weight full-term infants. Methods: We recruited two groups of schoolchildren between 8 and 11 years of age residing in the study catchment area: those who had been VLBWPIs (birth weight < 1,500 g); and those who had been normal-birth-weight full-term infants (controls, birth weight ≥ 2,500 g). Anthropometric and spirometric data were collected from the schoolchildren, who also completed a questionnaire regarding their physical activity. In addition, data regarding the perinatal and neonatal period were collected from the medical records of the VLBWPIs. Results: Of the 93 schoolchildren screened, 48 and 45 were in the VLBWPI and control groups, respectively. No significant differences were found between the groups regarding anthropometric characteristics, nutritional status, or pulmonary function. No associations were found between perinatal/neonatal variables and lung function parameters in the VLBWPI group. Although the difference was not significant, the level of physical activity was slightly higher in the VLBWPI group than in the control group. Conclusions: Among the schoolchildren evaluated here, neither growth nor lung function appear to have been affected by prematurity birth weight, or level of physical activity.

Abstract Low birth weight (delivery of an infant with less than 2500 grams) is owed to two main causes, either IUGR or pre-term delivery. It makes the newborn susceptible to many health issues from birth and through the adulthood life. Whoever IUGR is the leading cause of LBW in developing countries, and hence it is more reliable here in Sudan to study the risk factors that lead to it which are whoever mostly modifiable. This is a hospital based unmatched case-control study. A total of 134 (67 cases and 67 controls) mothers and their full-term newborn infants were included in the study. The participants were interviewed with a questionnaire and anthropometric measurements were obtained at the end of the interview. The data was analyzed using SPSS and Odd ratios of the risk factors were calculated. The main risk factors that found to influence the birth weight of our study participants were lack of maternal education, rural place of residence, bleeding during pregnancy, high blood pressure during pregnancy, inadequate spacing, lack of ANC follow up, not having iron supplementation and exposure to passive smoking during pregnancy.
