Filter by:The International Cohort Study of Children Born to Women Infected with Zika Virus (ZIKV) During Pregnancy study is a prospective, observational, international cohort study of children previously enrolled in the ZIP study or other ZIP 2.0 Protocol Team approved ZIKV-cohort study that will continue the longitudinal follow-up of children born with documented confirmed or presumptive in-utero ZIKV exposure ("ZIKV-exposed" cohort) and children born without documented confirmed or presumptive in-utero ZIKV exposure, matched by site and birth sex ("ZIKV-unexposed" cohort). Follow-up evaluations and assessments will allow for the determination and comparison of long-term neurodevelopmental outcomes among in utero ZIKV-exposed and ZIKV-unexposed children. Each participant will be followed for about 2 years, beginning at approximately 18 months through 42 months of age.
A phase 1, open-label safety, tolerability and early efficacy study of a Renal Autologous Cell Therapy (REACT) in patients with Chronic Kidney Disease from Congenital Anomalies of the Kidney and Urinary Tract (CAKUT) (REGEN-004)
Hereditary hemorrhagic telangiectasia (HHT) is linked to a dysregulation of angiogenesis leading to the formation of arteriovenous malformations (AVM): cutaneo-mucous telangiectasia and visceral shunts. The diagnosis is clinical and based on Curaçao criteria: recurrent epistaxis, cutaneo-mucous telangiectasia, hereditary signs and presence of visceral AVM. Pulmonary AVMs (PAVM) expose patients to many potentially life-threatening complications, such as strokes or brain abscesses due to the right-left shunt created and the lack of filtration barrier of the pulmonary capillary within the AVM. These patients should therefore have regular monitoring throughout their life by a chest CT scanner every 5 to 10 years in the absence of PAVM at the initial scan or more often if PAVMs are present. The management of PAVMs is based on their early detection and embolization in interventional radiology during which is set up within the afferent artery of the PAVM an embolizing agent, the coil. However, the risk of cumulative irradiation exposure from thoracic scanners and repeated thoracic embolizations over time could be reduces by a decrease of X-rays dose. A new thoracic CT imaging protocol validated in the United States in the primary screening of lung cancer, the ultra-low dose protocol, is a CT scanner acquired at an irradiation dose equivalent to that of a frontal chest x-ray and in profile. The dose reduction is of 40 times the usual dose of a chest CT scanner. The lung parenchyma has a high natural contrast on thoracic CT images and there are few adjacent attenuating structures allowing a drastic reduction of dose. However, from this dose, the image quality is degraded with an increase of the image noise. The diagnostic performances have to be confirmed with qualitative and quantitative measurements. Thus, the objective of this study is to compare the sensitivity and the specificity of the current scanner and the ultra-low dose scanner to reduce the exposure to X-rays.
The study aims to know the overall prevalence of granular deficits and their breakdown by type (anomaly of number, content or secretion) in a population of patients with hemorrhagic symptomatology after exclusion of other known causes. This study consists also to evaluate the association between the presence of a deficit in dense granules and (1) the intensity of the hemorrhagic phenotype (hemorrhagic score) (2) the nature of hemorrhages (post-operative, spontaneous, atypical...) -Evaluate the association between the type of deficit in dense granules and (1) the intensity of the hemorrhagic phenotype (hemorrhagic score) (2) the nature of hemorrhages (post-operative, spontaneous, atypical...)
Twenty percent of US adults report chronic pain symptoms. Both psychological symptoms and sleep issues commonly co-occur with chronic pain. Chronic pain is a frequently reported symptoms of Chiari Malformation (CM); however, the cause of pain symptoms is not fully understood, and pain is not associated with the extent of neural abnormality in CM. ACT is not a set of techniques, but rather a way of thinking. ACT encourages acceptance, as opposed to avoidance of unwanted feelings, all in the context of mindfulness (i.e., being aware of one's present environment and in tune with internal thoughts and emotions). ACT has been found to be successful at reducing pain perceptions and targeting multiple symptoms at one time. However, ACT has not been examined in CM and it is unknown whether ACT will improve sleep as well as pain-related symptoms. The purpose of the current study is to assess the efficacy of an online ACT intervention at reducing pain interference and sleep dysfunction symptoms in a sample with CM. It is hypothesized that CM patients may benefit from Acceptance and Commitment Therapy (ACT). More specifically it is hypothesized that the treatment group will report significantly less pain interference and psychological flexibility compared to the control group. It is also hypothesize that ACT will mediate the relationship between sleep dysfunction and pain interference. Based on power analyses the sample size will be 56. The sample will be recruited online and randomized to the treatment or control group. The intervention will consist of eight modules that are administered weekly over eight weeks. Additionally, a 7-day sleep diary will be administered the week prior to the intervention and the week after the intervention. Follow up assessments will be administered upon completion of the 8-week intervention (at the beginning of week 9), 1-month after, and 3 months after the completion of the intervention.
The study compares torque and arch width changes between four different orthodontic bracket prescriptions and determine whether changes in dental torque are correlated to changes in arch width at the end of orthodontic treatment. From an initial sample of 250 patients who sought treatment at the Department of Orthodontics (University of Valencia, Spain), a subsample of 76 patients (31 men and 45 women) were selected to meet inclusion criteria. The sample was randomly allocated into four groups according to four different orthodontic bracket prescriptions: Prescription A (n=22): Mini-Taurus® (Rocky Mountain©); Prescription B (n=17): Smart Clip® SL3 High Torque (3M Unitek©); Prescription C (n=18): Tip-Edge Plus® (TP Orthodontics©); Prescription D (n=19): Victory® (3M Unitek©). Initial (T0) and final (T1) plaster and digital study models were available for all patients. Measurements were taken from frontal and occlusal images of the models by a single experienced operator.
The study is designed as a randomized, Double-Blind, Placebo-Controlled, Parallel-Group Proof of Concept Study (section A) with a conditional dose finding follow up (Section B) to Evaluate the Efficacy on Cervical ripening, Safety, Tolerability and dose response of Subcutaneously Administered Tafoxiparin in Term Pregnant, Nulliparous Women with an unripe cervix undergoing Labor Induction. If the efficacy and safety profiles of Section A are conclusive in favor of tafoxiparin, the study will continue by adding two additional tafoxiparin dose groups in Section B.
Therefore, the aim of this study is to examine the effects of the short foot exercises compared to placebo exercises in the foot posture index after a daily period of 4 weeks.
In China, birth defects can reach as high as 5.6%, about 900,000 new cases of birth defects are added each year, making it the second cause of death for infants, with a total death rate of 19.1%. At present, China implements the three-level prevention and control system for birth defects, which is performed before marriage, before birth, and during the neonatal period. Newborn screening is the last line of defense against birth defects. Early screening diagnosis and timely intervention are extremely important, especially for diseases which can be preventive and treatable. This study aims to evaluate the clinical application of high-throughput targeting sequencing in newborns, and investigate whether this new technology can significantly shorten the time of examination, improve the diagnosis rate, guide the intervention treatments and promote prognosis for these disease.
