Filter by:Almost all infants born <29 weeks gestational age develop apnea of prematurity and are treated with caffeine. Type of diet and disease states may be significant contributors of variability in caffeine metabolism and pharmacokinetics (PK) in this population. This prospective, observational, open-label, opportunistic PK study will compare the population PK of caffeine between infants fed formula and infants fed exclusively breast milk; compare the activities of caffeine metabolizing enzymes between infants fed formula and infants fed exclusively breast milk; and determine the effect of hypoxia, hypotension, and infection on caffeine PK and metabolism in premature infants.
Infection is the principal cause of preterm births. Most (90%) women with preterm deliveries have no abnormal history. It is widely agreed that preterm delivery is often associated with bacterial vaginosis. One of the major difficulties at this time is that the diagnosis of bacterial vaginosis is based on heterogeneous criteria. The technique currently used is the Nugent score, but it lacks the characteristics necessary for widespread use in the general population. It must be performed on a fresh swab, and any delay in transporting it can cause drying that makes the test difficult to perform. The investigators have developed a rapid diagnostic tool for bacterial vaginosis using molecular biology based on a point of care model and obtained a patent (European Patent Office N° 2087134). In comparison with the reference techniques, our tool's performance has been excellent, in terms of specificity, sensitivity, and positive and negative predictive values. In particular, our work showed that 57% of the flora samples rated as intermediate on the Nugent score were in reality true bacterial vaginosis. Molecular biology therefore identifies a homogeneous population of women with vaginal flora anomalies. The investigators recently showed that the carriage of Atopobium vaginae and/or Gardnerella vaginalis >105/mL shortens the time to delivery in a population at risk of preterm delivery (PHRC 2006). Vaginal flora anomalies are therefore an important target for preventing preterm delivery.
Research question: Population of study: women diagnosed as term pregnancy in labor (control) and the other group diagnosed as preterm labor (cases). Intervention: measuring uterine natural killer cells . Outcome: uterine natural killer cells has a role in initiation of preterm labor. Research hypothesis: • Are uterine Natural Killer cells involved in the initiation of preterm labor ? Medical Application: • Possibility of prediction of preterm labor by assessment of Natural killer cells as well as preventing preterm labor by suppressing their activity .
The investigators will measure fetal lung volume by VOCAL and pulmonary artery resistance index in preterm fetuses and correlating the results with postnatal respiratory distress of the preterm neonates.
Low-dose aspirin started in the first-trimester has been associated with a decrease of preeclampsia, fetal growth restriction and preterm birth in high-risk pregnancies. Multiple pregnancies are considered a risk factor for all those adverse outcomes. The main objective of the current trial is to evaluate whether a dose of 80 mg of aspirin is associated with an improvement of birthweight compared to placebo in twin pregnancies.
The purpose of this study is to assess if Single Photon Emission Computed Tomography (SPECT) demonstrating cardiac innervation can be integrated into current electrophysiology voltage mapping system and provide improved guidance for ablation of PVCs.
The main purpose of this study is to evaluate the relative efficacy of topical lidocaine on reducing pain associated with the application of nasal CPAP in preterm infants
The purpose of this study is to evaluate the effect of oral progesterone supplementation in preterm labor on the prevention of recurrent uterine contraction and prolonging pregnancy period, and its side effect.
The purpose of this study is to evaluate the incidence of necrotizing enterocolitis and its effect over the secreting immunoglobulin A in the feces with the use of probiotics of the strain Lactobacillus acidophilus boucardii vs. Multispecies in premature newborns weighting less than 1500 g.
The purpose of this study is to investigate the pharmacokinetics of sildenafil which is used as treatment of pulmonary hypertension in neonate and preterm infant.
