Filter by:This study will explore lung function and respiratory health in school-aged children who were born prematurely at <32 weeks gestation. It will involve full lung function assessment, a questionnaire and discussion about respiratory health, and an exercise test using optoelectronic plethysmography (OEP) to measure breathing patterns.
Our main hypothesis is to consider that the detection of biomarkers on admission combined with the length of the cervix would improve the prediction of the latency period in case of preterm premature rupture of membranes (pPROM). The primary purpose of the protocol is to assess the performance of these tests to predict a latency period <48 hours in case of pPROM.
Through a multicenter case-control study on the risk factors of premature ejaculation in Shaanxi, to find out the related factors of the occurrence and development of premature ejaculation, to provide reference for personalized treatment, in order to improve the quality of sexual life of patients and partners.
Each year, between 50,000 and 60,000 children are born prematurely in France. Among them, 10% are born at 26 - 30 week's gestation and 5% are born before 26 week's gestation. Bronchopulmonary dysplasia (BPD) affects at least one-quarter of infants born with a birth weight less than 1500 grams. BPD is defined by the need for oxygen after 28 days of life in any children born prematurely. In addition, the severity of BPD can be categorized as mild (room air tolerated at 36 weeks), moderate (oxygen requirement between 22 and 29 %) and severe (oxygen requirement 30% or need for ventilation support). Bronchopulmonary dysplasia is responsible for significant respiratory morbidity and impaired neurological outcomes. Pulmonary imaging such as tomodensitometry, MRI or scintigraphy can be abnormal and therefore coud theorically be helpful for an early diagnosis. Unfortunatelly, theses examinations are irradiating, expensive or difficult to perform in an everyday practice. Therefore lung imaging for BPD diagnosis. Is not recommanded in current official guidelines. Pulmonary ultrasound has already been studied in premature newborns. A pilot study carried out on 21 patients showed that pulmonary ultrasonography at one and two weeks of life could predict the risk of bronchopulmonary dysplasia. The score used in this study was the LUS score previously validated by Brat et al. Advantages of this examination are to be non-invasive and easily performed at the patient's bedside. Nevertheless this study focused on a small population with a low number of moderate / severe dysplasia. In addition, Czernik et al. have highlighted that the index of myocardial performance of the right ventricle was increased at seven and ten days of life in children who subsequently developed BPD. The investigators propose in this study to evaluate a new prediction score for DBP, the modified LUS score, associating the LUS score with an echographic evaluation of the right heart (myocardial performance index).
Objective: Evaluate the effectiveness and safety of transcutaneous electrostimulation of the posterior tibial nerve alone and combined with standard pharmacological treatment, in men with primary premature ejaculation, compared to standard pharmacological treatment. Patients and methods: Randomized controlled clinical trial. Patients diagnosed with premature ejaculation attending Boston Medical Group clinics in Colombia and Spain will be included. Participants will be assigned by randomization to one of three treatment groups: - Group 1: Tens + placebo drug therapy - Group 2: Standard treatment (paroxetine 20 mg) + placebo therapy - Group 3: Tens therapy + standard treatment (paroxetine mg) The change in intravaginal latency time measured with the couple's sustained stopwatch, the change in the PEDT scale, the perception of the change in their initial condition after treatment (Global Clinical impression of change scale), and the change in different domains of the EP (PEP Scale - Profile Ejaculation Premature) at the end of treatment (week 12) and at three months of follow-up (week 24).
Eligible eyes are randomly assigned into two groups. Group A receive Fasudil eye drops (concentration 0.5 percent) twice daily. Group B, receive artificial tears drop with the same frequency. Retinal specialists who are expert in Retinopathy Of Prematurity field will perform fundus examination regularly. The examiners are blind. The progression of normal retinal vascularization and need to treatment will be documented and compared between the two study groups. The topical eye drops are used until the retinal vascularization are complete (45 week after LMP) or the patient needs to be treated.
Cranial USG is simple and easy method to assess preterm infant brain. Some studies showed that brain volumes of preterm infants could be calculated by measurement of 2D distances. Our aim in this study was to compare brain volume obtained by USG and MRI.
Rationale: Due to accelerated germ cell loss, infertility is a major problem in girls with Turner syndrome (TS). Therefore, cryopreservation of ovarian tissue or oocytes before exhaustion of the ovarian reserve may preserve fertility in patients with TS. However, in the majority of females with TS , the ovarian reserve is exhausted before the age of menarche. Early markers indicating and predicting the ovarian reserve are necessary. During mid-childhood the hypothalamic-pituitary-gonadal (HPG) axis is quiescent and gonadotropins are usually unmeasurable. Nonetheless, this axis is active during infancy. Therefore, gonadotropins are measurable with peak values at 3 months of age and with lower (but still measurable) values at 9 months of age, in a period called the minipuberty. The aim of this study is to find markers of ovarian capacity, during the minipuberty, in order to predict ovarian reserve in the future. Objective: The hormonal range of LH, FSH, AMH, inhibin B, testosterone and estradiol in girls with TS during the minipuberty and the relation of the hormone serum levels with the karyotype. Study design: A prospective, cohort study with a duration of 3 years. Study population: Girls with a pre- or perinatal diagnosis TS who are born in a medical centre in the Netherlands during the duration of the study Main study parameters/endpoints: Serum levels of FSH, LH, AMH, inhibin B, testosterone and estradiol at the age of 3 and 9 months.
The Environmental Factors and Embryonic Development Project was set up to investigate environmental exposures and behavioral factors responsible for embryonic dysplasia and gestational complications in pregnant women.
Ventricular repolarization, measured by corrected QT interval (QTc), is influenced by sex hormones. A QTc above 460msec predisposes to the risk of "torsades-de-pointes"(TdP). The investigators have recently shown that estradiol determines an increase in QTc elongation and progesterone shortens it. In addition, high gonadotropin levels (FSH or LH) are associated with QTc prolongation. Hypergonadotropic hypogonadisms (low progesterone and high gonadotropins) are therefore hormonal situations that promote QTc prolongation. Premature ovarian insufficiency (POI) is one of them. Its management is based on the prescription of hormone replacement therapy (HRT). Epidemiological studies have shown that these patients would be at increased risk of cardiovascular mortality. Our team is interested in the effect of this pathological hormonal situation and its HRT on ventricular repolarization in order to define whether this is a population at risk for long QTc.
