Active clinical trials for "Premature Birth"

Pooling effort to collect previously reported data on QTc time in former preterm neonates, and compare these data to controls. At present and based on a recently conducted systematic search, there are conflicting data on the potential QT interval prolongation (all Bazett) in former extreme low birth weight (ELBW, <1000 g) infants or preterms. Consequently, if investigators truly want to assess the presence or absence of either a difference or a prolongation of QTc intervals in this specific population, pooling of published data is likely the most effective approach (potential number of cases = 24 + 49 + 93 = 166; potential number of controls in the same studies = 24 + 53 + 87 = 164), preferably based on individual data. Although the sample is to a large extent pragmatic (as available), the investigators hereby aim to target the 5 ms QTc prolongation applied by the authorities (FDA, EMA) in paired healthy adult volunteer studies as 'golden' standard as primary outcome variable [EMA guideline, FDA guidance].

Project Summary: The prevalence of preterm birth ranges from 5% to 18% across 184 countries, and an estimated 15 million infants are born preterm globally. These infants with an immature immune system and gastrointestinal tract are at risk of complications of premature birth, which is the leading cause of neonatal death. According to researcher hypothesis for this study, there is role of probiotics in promoting food tolerance and reducing the incidence and severity of Necrotizing Enterocolitis (NEC) and death related to NEC in pre-term VLBW infants. In the current study, we will examine the effects of probiotics in premature infants and figure out the optimal intervention through randomized controlled trial (RCT). A prospective, masked, randomized single blinded controlled trial will be conducted in the neonatal intensive care unit (NICU) of Services Hospital Lahore. In this trial the treatment group will receive the probiotics during their first month of life, and the control group will receive no treatment. Primary outcome will be the incidence of death or NEC (≥ stage 2). Death is included as a primary outcome because it is a competing variable of NEC. The x2 test will be used to analyze the categorical data, along with Fisher's exact test when applicable. The Student's t test will be used for continuous data. A logistic regression model will be used to analyze the treatment effects on the primary and secondary outcome variables (death, NEC, and sepsis). Values will be expressed for mean and standard deviation. Statistical significance is set at P-value of 0.05. The objective of this study is to confirm the evidence and to get the more reliable and authentic results regarding the more effective treatment of NEC in preterm neonates. In this way, the researcher shall be able to improve the outcome of premature births and to reduce the complications by increasing the cure rate. Similarly, it will help the researcher to improve knowledge for better management of NEC in neonates.

The aim of the study is to investigate levels of brain perfusion and elasticity in preterm neonates when they reach the estimated due date and to compare the data with magnetic resonance imaging at term. Contrast enhanced ultrasound (sulphur hexafluoride) and ultrasound-assisted elastography will be used to evaluate the state of brain perfusion with ultrasound. Different appropriate imaging sequences will be used regarding MRI, including asl-perfusion. Neonates recruited from the Neonatal Intensive Care Unit (NICU) of Turku University Hospital will be recruited.

To study the safety and efficacy of intranasal administration of exosomes derived from mesenchymal stromal cells on long-term neurodevelopmental outcome in extremely low birth weight infants born at gestational age 25/0-27/6 weeks.

Preterm birth (PTB) complicates 13% of all pregnancies worldwide and is the most important cause of neonatal morbidity and mortality. Women with a twin pregnancy are at increased risk of preterm delivery. In the Netherlands, approximately 50% of women with a multiple pregnancy deliver before 37 weeks of gestation (WoG), of whom 9% deliver before 32 weeks. Evidence based treatment guidelines concerning prevention of PTB are not available in Europe. Expectant management is usual care with interventions only in terms of a tertiary prevention of PTB according to guidelines for premature rupture of membranes, premature labour or other pregnancy complications. The studies done on this topic included women at different stages of the second trimester so the question of the onset of cervix shortening and its impact on PTB is not answered yet. The critical period for a maximum impact of the pessary treatment on PTB is still to be verified. Up to now only the ProTwinTrial addressed the long-term outcome of the newborns, so here data and evidence is clearly missing. The investigators want to assess the impact of a cervical pessary treatment in twin pregnancies with cervical shortening on children's survival without neurodevelopmental disability at the age of 3 years at 3 different stages of the second trimester (16-20 (early) vs. 20-24 (middle) vs. 24-28 (late) weeks of gestation).

There are few safe, effective, and affordable interventions to improve pregnancy outcomes in low resource settings where the highest rates of poor birth outcomes occur. L-citrulline is naturally found in many foods and is changed into another important amino acid, L-arginine, in the body. L-arginine is important for the growth of a healthy placenta and healthy baby. Adding L-citrulline to the diets of pregnant women may be an effective and affordable way to improve the health of their babies.The goal of the AGREE trial is to test whether a dietary supplement containing a common food component, an amino acid called L-citrulline, can help pregnant Kenyan women at risk of malaria have healthier pregnancies and healthier babies. 2,960 pregnant Kenyan women will be enrolled and randomly assigned to take either a twice daily dietary supplement containing L-citrulline or a placebo supplement without additional L-citrulline. Maternal participants will be seen every month until delivery and at weeks 1 and 6 after birth. Infants will also be followed up at ages 6, 12, 18, and 24 months. The primary outcome of the study is 'adverse pregnancy outcome', a composite of foetal loss (miscarriage or still birth), preterm birth, low birth weight, small for gestational age or neonatal mortality. The results of the AGREE trial could help to guide obstetric and public health policy and provide a sustainable solution that could be implemented at the community level.

Objective of the study: To examine cognition, motor function, executive functions, speech and language development, behaviour, psychosocial functioning,academic achievement, physical morbidities and growth of MLPTI at the age of 9 years and correlate this with BSID-III-NL scores,growth parameters and body composition at the age of 2 years. Study design: This study will be a prospective open, non-therapeutic exploratory cohort study and can be seen as a continuation on the study with protocol identification number NL50800.094.14, performed in the NWZ Alkmaar between 2014 and 2016. This was a study on growth and neurodevelopment of MLPTI in the first 2 years of life. Study population: The study population is a group of 200 moderate and late preterm children who were born in the NWZ Alkmaar between 2014 and 2016. 100 of these children participated in the aforementioned study on growth and neurodevelopment at the age of 2 years. The oldest children in this group will reach the age of 9 years in 2023. Brothers/sisters/friends of these children aged between 8 and 10 will be asked as control group (n=50). Primary study parameters/outcome of the study: The main study parameters are the IQ-scores of the WISC-V, the motoric scores of the Movement-ABC, the executive functions of the EMMA Toolbox, the presence of morbidities, the growth pattern and the mean blood pressure at 9 years of age. Secondary study parameters/outcome of the study: Secondary outcome parameters are the he behavioural and psychosocial outcomes of the CBCL and the SDQ scores, speech-and language-developmental scores of the CELF-5-NL and CCC-2-NL, MCH Feeding Scale and Teacher Report Form (TRF) scores. Other outcome parameters are the relation between the 9-year outcomes and the BSID-III scores at the age of 2, and the differences between the MLPTI and the control group. Furthermore, we aim to determine the relation between growth and body composition in the first two years of life and the waist circumference, growth parameters and blood pressure at the age of 9 years.

Preterm birth (PTB) is a major challenge to perinatal health. It accounts for 75% of perinatal deaths and more than 50% of long-term neurological disabilities. Neonates born preterm are also at risk of significant comorbidities, for example respiratory distress syndrome, chronic lung disease, retinopathy of prematurity, necrotizing enterocolitis, intraventricular haemorrhage and sepsis in the short term, as well as cerebral palsy, motor and sensory impairment, learning difficulties, and increased risk of chronic disease in long run. Twin pregnancy is associated with a higher risk of PTB when compared to singleton pregnancy. The National Vital Statistics reveals the PTB rate is 8.2% and 60.3% in singleton and twin pregnancy respectively in 2018. The mechanism of PTB in twin pregnancy is not completely understood and may be different from that of singleton pregnancy. At present, there are no good strategies to prevent PTB in twin pregnancy. In singleton pregnancy, metformin has been used for the treatment of gestational diabetes in pregnant women with obesity/ overweight or polycystic ovarian syndrome (PCOS). The rate of PTB of pregnant women with PCOS is significantly lower after using metformin. A decreasing trend of PTB is also noted after metformin use in obese pregnant women without PCOS. There is no study to investigate the effect of metformin in twin pregnancy. Premature uterine and amnion stretching in twin pregnancy can trigger preterm labour by increased prostaglandin synthesis and interleukin-1, activation of activator protein-1, expression of connexin-43 and stimulation of stretch dependent focal adhesion signaling. Inflammation is another risk factor for PTB. Metformin is an anti-inflammatory agent which can suppress inflammatory cytokines production and downregulate AMP-activated protein kinase medicated connexin-43 and nuclear factor κB activation. Anti-inflammatory actions of metformin can also reduce production of nitric oxide, prostaglandin E2 and pro-inflammatory cytokines through inhibition of NFκB activation in macrophages. Another possible mechanism to prevent PTB is the inhibition of mammalian target of rapamycin complex 1,which has a role in the timing of birth, by AMP-activated protein kinase. Therefore, metformin can be potentially used to prevent PTB in twin pregnancy. However, its effect in twin pregnancy has not been studied. The objective of the study is to determine if the use of metformin in twin pregnancy can prevent PTB.
