Filter by:This will be a randomized single sequence open label study. This study is designed to determine if chronic dosing with efavirenz (EFZ) will have an effect on the pharmacokinetics (PK) of intravenously-administered retosiban in healthy volunteers. The study consists of screening (28 days), treatment (1 dosing session) and follow-up (7 to 14 days) period, and the total duration of study participation for each subject will be approximately 8 weeks. During the treatment period, subjects will be admitted to the clinical research unit the day before dosing (Day 1) and will remain until completion of the last assessment on Day 20. All subjects will receive on Day 1, a 6 milligrams (mg) bolus of retosiban for 5 minutes (min), followed by a 6 mg/hour (hr) infusion for 12 hrs. On Day 2, a washout day will occur. On Days 3-17, subjects will receive EFZ 600 mg once daily in the evening. On Day 18, subjects will receive a 6 mg bolus of retosiban for 5 mins, followed by a 6 mg/hr infusion for 12 hrs plus a 600 mg dose of EFZ.
The aim of this study is use of ACTH as a predictive marker in patients of threatened preterm labor .
Children born prematurely are of greater risk of developing chronic lung disease (Bronchopulmonary Dysplasia). With an increase in the amount of premature children, we expect an increasing number of children with BPD. Today we do not have many ways of predicting or treating this condition, and the children are usually in hospital for several months after birth. Many are dismissed with home oxygen. Children with BPD are typically often re-submitted to hospital with respiratory disease the first couple of years, and some of them have problems throughout childhood and into adulthood. Other scientists have found a correlation between BPD and Chronic Obstructive Pulmonary Disease (COPD). The condition as well as the treatment (steroids), are associated with great risk of adverse effects as Cerebral Palsy, blindness, deafness and mental retardation. The investigators wish to find a safe way to identify the children in greater risk of developing BPD, who could therefore benefit from a more intensive treatment.An early diagnosis would increase the possibility of predicting the prognosis. Other studies have proven a connection between both low vitamin A and D and high exhaled nitrogen oxide (NO) with lung disease. With this trial the investigators wish to make a reference material for NO and vitamins A and D in infants admitted to the neonatal department at two hospitals in Denmark, both with and without treatment with nasal Continuous Positive Airway Pressure. The investigators furthermore wish to describe an eventual connection between BPD and these factors by examining a large group of children on 7 specific occasions within the first two months of life and at a one year follow up.
This will be a randomized, placebo-controlled, single, oral dose, four-way Williams crossover study design in healthy male and female subjects. The study consists of screening (28 days), treatment (1 day/dosing session) and follow-up (7 to 14 days) period and the total duration of study participation for each subject will be approximately 9 weeks. Each subject will participate in 4 dosing sessions separated by a minimum 7-day washout period. All subjects will receive single doses of retosiban 100 mg, (treatment A) retosiban 800 mg (Treatment B), moxifloxacin 400 mg (Treatment C) and placebo (Treatment D) in one of the four treatment sequences (ABDC, BCAD, CDBA, DACB) following a Williams design Twelve-lead ECGs and continuous Holter monitoring, clinical laboratory safety tests, vital sign measurements, physical examinations, adverse event reports, and pharmacokinetic samples will be collected throughout the study. In each study period, cardiac conduction will be measured using a 24-hour continuous 12-lead Holter monitor from the morning of Day 1 (dosing) until the morning of Day 2.
This is a two part study. Part A of the study will evaluate the metabolites of GSK221149 following single and repeat oral dosing and will also assess the pharmacokinetics of GSK221149 when administered with a potent CYP3A4 inhibitor Ketoconazole. Part B of the study will look at the pharmacokinetics of GSK221149 following a high fat meal.
To demonstrate if indomethacin associated to conventional treatment for preterm labor is useful to delay delivery and to improve neonatal morbimortality in women with preterm labor with high risk of intraamniotic inflammation
The investigators study objective is to investigate the effectiveness of vaginal micronized progesterone in prolonging pregnancy after an episode of preterm labor which responded to tocolytic treatment. Furthermore, the investigators aim is to study the mechanisms of actions of progesterone supplementation by examining its effect on the two components of parturition: cervical ripening and myometrial contractility. The investigators will utilize transvaginal ultrasound to assess the changes in the cervical tissue, and non-invasive trans-abdominal uterine EMG to assess the uterine muscle activity. The investigators will also look at the effect of progesterone on contraction frequency by tocodynamometer (TOCO), though EMG is expected to provide much more information.
Use of modern diagnostic tools e.g. fetal fibronectin and ultrasound measurement of cervical length to diagnose preterm labor can result in improved outcomes compared to traditional diagnosis based on digital examination to measure cervical change.
The purpose of this study is to compare the tocolytic efficacy, effectiveness and safety of Atosiban in comparison with the combination of Atosiban and Nifedipine together.
Introduction: Preterm labor (PTL) is an important obstetric intercurrence that affects 5 to 10% of pregnancies. Among the known factors of PTL etiology are PTL occurrence in previous pregnancies, multiple pregnancies, polyhydramnios, vaginal bleeding during pregnancy, premature membrane rupture (PMR) and bacterial vaginosis. Despite the advancement achieved in Neonatology, morbidity and mortality resulting from high rates of preterm births have remained constant in the last few decades. Objective: This study aims at evaluating maternal and perinatal outcomes of pregnant women with a history of preterm labor in previous pregnancies and submitted to active search for vaginal infection. Material and Method: It is a prospective-cohort epidemiological study to be conducted in Botucatu/SP. Two study groups (G1 and G2) will be formed, and each of them will comprise 140 pregnant women with a history of preterm childbirth. G1 will be related to the active search and etiological diagnosis of lower genital tract infections, and G2 will be related to non-search for such infections, for which the routine care protocol of primary health units in the city of Botucatu will be maintained. Care propedeutics for the pregnant women (G1) will include the performance of direct examination of vaginal content stained by the Gram method, culture in Diamonds medium, polymerase chain reaction (PCR) of endocervical secretion collected in the primary health care services in the city at two moments: prior to the 20th gestational week (M1) and at the 36th week (M2). Moment M3 will take place after childbirth for evaluation of the perinatal outcome.
