Filter by:Preterm and very preterm infants are at risk of developing encephalopathy of prematurity and long-term neurodevelopmental delay. Magnetic resonance imaging (MRI) allows the characterization of specific features of encephalopathy of prematurity, including structural changes of brain white matter and gray matter. This study wants to investigate important evidence that early repeated high-dose rhEPO(5250 IU/kg) treatment improves long-term neurological outcomes in very preterm infants and without obvious adverse effects.
Positive end-expiratory pressure (PEEP) is used in premature infants receiving mechanical ventilation to maintain lungs open and facilitate gas exchange. When ventilation/perfusion mismatch is present, areas of the lung that are open for gas exchange do not match up with areas of the lung that are receiving blood for gas exchange. This study measures the feasibility of enrolling and completing study maneuvers in premature infants for a prospective study measuring the responsiveness of V/Q mismatch to changes in the amount (or level) of PEEP.
Pretern premature rupture of the membranes (PPROM) remains the leading cause of preterm deliveries and neonatal mortality and morbidity. PPROM is defined as rupture of the fetal membranes prior to 37 weeks' gestation. PPROM complicates 2-4% of all pregnancies and accounts for approximately 30 % of preterm births. The etiology of PPROM remains elusive. PPROM is one of the main causes of prematurity and its complications, such as newborn respiratory distress syndrome, neonatal sepsis, necrotizing enterocolitis, intraventricular hemorrhage, perventricular leucomalacia, varying degrees of lung hypoplasia and bronchopulmonary dysplasia. All these factors contribute greatly to an increase in neonatal morbidity and mortality Management of PPROM followed actual guidelines. Conservative management to prolong a pregnancy is a classical approach to treat PPROM before 34 weeks' gestation in association with antibiotic therapy and corticosteroids. Maternal and neonatal data were collected from maternal and newborns medical records.
Two groups will be recruited. The first group are pregnant ladies that have unequivocal rupture of fetal membranes that is diagnosed by seeing the amniotic fluid leakage in the vagina. The second group are normal pregnant ladies without rupture of membranes. both groups will be tested by taking vaginal washing fluid. Quantitative and qualitative pregnancy tests will be measured in this fluid.
From November 2014 to October 2015, a multi-centers retrospective study was conducted to collect compliance, and 8 three-level hospitals from China were included. The infants survived to a postmenstrual age of 36 week with birth weight less than 1500g and without congenital disease. The birth weight, gestational age, morbidities and poor outcomes( death, cerebral palsy, cognitive, et al) were recorded. Data were analyzed with Chi-square test to observe the relationship between morbidities and poor outcomes. And the predictive effect on the number of the top three morbidities were analyzed by Logistic regression analysis.
Preterm birth (PTB) occurs before 37 weeks of gestation and is a major cause of neonatal mortality and morbidity. PTB results from heterogeneous influences. One of them is the inherited predisposition of spontaneous PTB, and another is the change in the placental microbial composition as this can cause infections, which lead to inflammation, a common cause of preterm birth. Interestingly, maternal periodontal disease is an independent risk factor for PTB, low birth weight and fetal growth restriction. Immune responses to infectious events or inflammation as well as genetic predisposition to inherited conditions have successfully been studied by using assessing genetic expression profiling. The molecular signature is sets of genes, proteins, genetic variants or other variables that can be used as markers for a particular phenotype. Child morbidity from malnutrition resulting in poor growth and stunting remains a major public health issue that affects the local population just like PTB. While risk factors for malnutrition are multifaceted, there is also a hypothesized causal link between early gut microbiome disruption that leads to chronic malnutrition in otherwise healthy infants. Molecular signatures including the intestinal microbiome development of preterm infants will be evaluated and compared to the term (≥37 weeks' gestation) counterparts. Moreover, a comprehensive examination of possible factors associated with poor growth and poor motor- and neurodevelopment will be assessed. In this extension study: The primary goal for the child is to evaluate the perturbation in the development of the genomic profile including intestinal microbial habitat from children in a rural and limited-resource setting from birth to two years of life.
The aim of this study is to investigate the changes of amino acid metabolic profiles in different nutritional stages of preterm infants and determine the effects of nutritional intervention on the amino acid metabolic status of preterm infants.
The investigators compared advantages and disadvantages of two forms of noninvasive respiratory support -noninvasive high-frequency oscillatory ventilation (nHFOV) or nasal continuous positive airway pressure (nCPAP) -as a primary mode of ventilation in premature infants with RDS．
Our current reflexion is that sensory dys-stimulations, including vestibule-proprioceptive disorders and unbalanced between brain and brainstem maturation of the neonatal period involve an early deviant development for immature infants that will be cascaded through the brain scaffolding and later development. The primary purpose is to determine whether the Early Psychomotor Therapy Intervention Program improves development and behavior in very preterm infants (VPI) at 24-month corrected age (CA).
Several reports have shown the utility of PVC ablation with cryo catheters. The aim of this study is to compare the outcomes and safety of Cryo vs. RF for PVCs.
