Active clinical trials for "Birth Weight"

Human milk is the best source of enteral nutrition for the preterm infant. However during the infants first hours and days of life breastmilk from the own mother is usually not available. Until May 2012 the practice in the Neonatal Division of the Department of Pediatrics /Medical University Vienna was to start with formula feedings within the first 6 hours of life of a premature infant and switch over to breastmilk as soon it was available. In June 2012 the investigators changed this feeding regimen and started to use single donor milk of mothers of preterm infants for the first hours and days of the preterm infants life. In a prospective observational study the investigators evaluated the impact of single donor milk from preterm infants on time to full enteral feedings, gastrointestinal tolerance and NEC incidence in preterm infants with a birthweight below 1500 grams and a gestational below 32 weeks. Data will be compared with a historical control group starting with preterm formula as source of enteral nutrition. The investigators hypothesize that starting enteral nutrition with single donor milk of mothers from preterm infants with shorten time to full enteral feedings.

The major aim is the follow-up of the highest risk group (< 32 weeks gestation/ < 1500 birthweight) and their controls of the Bavarian Longitudinal Study (BLS) at the age of 24-27 years. The focus will be the identification of risk, protective and resiliency factors for cognitive and behavioural development and quality of life. MRIs of the central nervous system will be conducted to examine aberrant activation patterns during the "attention network task" in stratified subgroups. Data driven MRI methods will be evaluated in relation to clinical, behavioural and developmental parameters.

This study was an observational study to estimate the prevalence of Persistent pulmonary hypertension of the newborn (PPHN) among term or near-term infants with severe respiratory disease.

A study to compare growth, development of the intestinal bacterial environment, and other short term outcomes in groups of babies fed primarily their own mother's milk compared to those who receive primarily donor human milk. The investigators hypothesize that infants who receive primarily their own mother's milk will have better growth, a more diverse intestinal bacterial environment, and possibly some improved short term outcomes such as better feeding tolerance and lower rates of infection.

An observational study comparing outcomes of Extremely Low Birth Weight (ELBW) infants that were monitored with non-invasive Transcutaneous CO2 (TCCO2) monitor to infants that were not monitored by TCCO2 monitor.

This observational study evaluated the performance of new lab tests in detecting candida species fungal infections in extremely low birth weight (ELBW) infants quickly and accurately. 19 NICHD Neonatal Research Network sites enrolled 1,500 infants with birth weights ≤1,000g; 100 of these infants later tested positive for candidiasis. Blood, urine, and lumbar puncture samples were collected whenever other specimens were obtained from participants for cultures. These samples are being tested using the new methods and compared with standard culture results. Surviving study subjects completed a neurodevelopmental evaluation at 18-22 months corrected age.

The most persistent and intractable cause of infant and child mortality and morbidity in the US remains preterm and low birthweight deliveries. Pregnant women in the United States experience the highest incidence of these complications among developed countries. Even more disturbing is the observation that immigrant Hispanic women experience worsening birth outcomes the longer they live here, despite increasing access to prenatal care, improved socio-economic status and better education. The purpose of this study is to identify the potential acculturation-related risk factors for preterm and low birthweight (PTLBW) delivery among Hispanic women of varying lengths of US residency. It is hypothesized that changes in factors associated with acculturation, such as poor nutritional intake, job stress and occupational exposures to pesticides or other hazards, and certain types of genital infections, can best explain the worsening of pregnancy outcomes among Hispanic immigrant women.

Globally, 15% of all babies, amounting to 20 million infants each year, are born low birthweight (LBW), defined less than 2500 grams (5.5 lbs). Compared to normal weight infants, LBW infants are at higher risk of morbidity, mortality, and poor growth (Risnes et al 2011; Larroque et al 2001; WHO 2006). The main causes of LBW are preterm birth, intrauterine growth restriction (IUGR), or their combination. Unfortunately, there is a paucity of information around feeding practices and optimal feeding strategies for this population, particularly for LBW infants who struggle with breastfeeding or growth. This study hopes to address these gaps.

Extremely premature children benefit from specific follow-up that requires high nutritional intake and the use of specific therapies that expose them to the risk of nephrocalcinosis. Other identified risk factors are extreme prematurity and intrauterine growth restriction. The incidence of nephrocalcinosis in very premature infants is unclear, ranging from 7 to 64%. Most studies are observational and only few case-control studies can properly analyse the risk factors for nephrocalcinosis in significant populations that include only preterm infants. This nephrocalcinosis of prematurity regresses spontaneously in more than half of the cases, but has been associated with a risk of long-term complications: impaired renal function, high blood pressure, etc. This is an aggravating factor in the context of prematurity, which has been associated with an increased risk of renal impairment and hypertension in childhood and adulthood. For all these reasons, nutritional intakes and therapeutics are monitored very closely and a renal ultrasound is routinely performed at discharge at 35 weeks of corrected gestational age in all children who are born at a gestational age ≤ 32 weeks and/or birth weight ≤ 1500 g.

The aim of the project is to assess the association between exposure to per- and polyfluoroalkyl substances (PFAS) via drinking water in pregnancy and birth outcomes (i.e. growth retardation, premature birth, and congenital developmental defects) and maternal morbidity (gestational hypertension, diabetes and preeclampsia) in a prospective population-wide register study.
