Exenatide Pregnancy Registry - Type 2 Diabetes in Pregnancy
Birth DefectsType 2 Diabetes1 moreThis is an observational, prospective cohort study describing pregnancy outcomes in women with pre-existing (prior to pregnancy) type 2 diabetes who have been exposed to any formulation of exenatide during pregnancy. The pregnancy registry will compare the occurrence of the pregnancy outcomes of interest with those collected from a prospective group of women with pre-existing type 2 diabetes who have been exposed to one or more antidiabetic medications other than exenatide during pregnancy. Insulin exposures are acceptable in both groups but must be in addition to one or more other antidiabetic medications in the non-exenatide group. The primary study objective is to evaluate the percentage of major birth defects (i.e., those that caused significant functional or cosmetic impairment, required surgery, or were life-limiting) following use of exenatide during pregnancy for treatment of type 2 diabetes compared to the percentage of major birth defects following use of one or more antidiabetic medications other than exenatide during pregnancy for treatment of type 2 diabetes. The secondary objectives of the Exenatide Pregnancy Registry are to evaluate the percentage of other adverse pregnancy outcomes (e.g., spontaneous abortion, stillbirth, preterm birth) and any potential impact of exenatide use during breastfeeding among pregnancies or births in women who used exenatide for pre-existing type 2 diabetes: This study is being conducted in the United States (US). Enrollment in the Registry is voluntary. The Exenatide Pregnancy Registry is sponsored by AstraZeneca and is managed by INC Research, LLC. The scientific conduct and analysis of the Registry is overseen by a Registry Review Committee (RRC) consisting of experts in maternal and fetal medicine, teratology/genetics, epidemiology, type 2 diabetes in pregnancy and/or pediatrics.
Biomarkers, Neurodevelopment and Preterm Infants
PretermNeurodevelopmental Disorder1 moreApproximately 2% of neonates in the US are born very preterm. Preterm births are associated with impaired cognitive, language and motor function, and increased risk for autism spectrum disorders. Epidemiological studies indicate a dose-response relationship between gestational age at delivery and cognitive impairments, with the most immature of newborns being the most susceptible to developmental delays. Sensitive and reproducible biomarkers of long-term neurocognitive impairments are currently lacking. The investigators seek to identify epigenetic markers that mediate the relationship between adverse prematurity-related exposures and neurocognitive impairments. The overarching hypothesis of this proposal is that DNA methylation profiles of CD34+ hematopoetic progenitor and stem cells from very preterm infants can be used as a risk-stratifying biomarker for predicting neurocognitive impairment in childhood.
Vaginal Progesterone for the Prevention of Preterm Birth in Twins
Premature BirthTwin PregnancyThis trial is a randomised, multi-centre, 2 x 2 factorial designed pilot trial with two factors of 200mg vs. 400mg progesterone self-administered daily from 11-14 weeks' gestation vs. 20-24 weeks' gestation, to compare the median gestational age (in days) at delivery between the comparison groups.
Effect in the Short and Medium Term of Different Techniques of Tactile Stimulations on Neurological...
Very Preterm InfantPremature birth deprives infants of sensory stimulation. Tactile stimulation such as massage pressure with kinesthetic movement significantly increases the weight, bone density and shorten the duration of stay of premature babies who benefits. Studies using vegetable oils show an increase in the effect on weight gain by cutaneous absorption. The mechanism is probably vagal (stimulation of baroreceptors and skin mechanoreceptors) since it is found in children stimulated an increase in the vagal activity, acceleration of gastric emptying and an increase in the secretion of insulin and IGF1. Few studies have evaluated the effects of massage on the medium-term neurological development in preterm infants and the effect of the essential oils in the effectiveness of touching the short and medium term massage. The aim of the investigators study is to evaluate the neurological development in the short and medium term in premature newborns and biological effects of massage with essential use of vegetable oil. Methodology and possible collaborations This is a monocentric, randomized, controlled, in a neonatal intensive care unit. It concerns 60 children born between 26 and 30 weeks of amenorrhea. Each child receives massage randomized with or without oil ISIO 4. The treatment is administered 10 minutes twice a day for 10 consecutive days watching for signs of intolerance. The quality of the spontaneous motility between 12 and 20 weeks of age corrected is used as the first neurological assessment criterion. The questionnaire (ASQ) Bricker and Squires (translated into French by Martha Bonin et al.) is used to 6, 12, 24 months corrected age and completed by the parents as a second neurological endpoint. A lipid chromatography is performed at the beginning and at the end of the massage time and at the deliverance from NICU for comparing the profile of children's fatty acids. Expected results Show that there is an improvement in the neurological development in children who received massage with vegetable oil ISIO 4. Show that there is a skin absorption of essential fatty acids that can substitute for a known major deficiency in premature even in infants fed breast milk.

Oral Magnesium Supplementation in Athletes With Premature Ventricular Contractions or Premature...
Ventricular Premature ComplexesAtrial Premature ComplexesMagnesium is a mineral which is essential to many of the processes which happen in the body. This includes normal function of muscles; including the heart. Studies have shown that oral magnesium supplementation can help reduce the frequency of extra heart beats (premature ventricular contractions (PVC) and premature atrial contractions (PAC)) while also reducing the severity of their associated symptoms. Oral magnesium supplementation has yet to be investigated in athletes with lots of PVCs and/or PACs. Most of the magnesium in your body is stored in the bones. Your body may take magnesium from your bones to maintain magnesium levels in your blood. This makes it possible for people to have low levels of magnesium in their body but normal levels in their blood. Over time, this process can decrease the total amount in your body and impact other body functions. Magnesium is also lost in sweat making athletes more vulnerable to having low levels in their body. Magnesium is particularly important in the function of the myocardium (heart muscle fibers). It has been proposed that the PVCs and PACs experienced by some people are a result of low levels of total body magnesium. Current drug treatments to control PVCs and PACs include medications such as beta blockers. These treatments are not without their side effects. Generally, these medications are only effective if individuals do not have a structural heart disease. These drugs may also decrease your ability to exercise and are banned by some governing bodies in sport. The hypotheses of this study are: Oral magnesium supplementation reduces the frequency of PVCs and/or PACs. Oral magnesium supplementation reduces the symptoms associated with PVCs and PACs. To be eligible for the study, individuals will be required to have a certain number of PVCs and PACs in a day. This study will involve two groups of participants. A total of 25 participants will be recruited for each group resulting in 50 participants in the study. During the study, one group will take a daily magnesium capsule for 12 weeks before switching to a placebo for 12 weeks. The other group will have the placebo intervention before switching to magnesium. Participants will be randomized into one of the two groups and will remain blinded until their participation in the study ends. The research team will also be unaware of each participant's current intervention however, this information will be available in case of medical emergency. Participants will be asked to attend one screening visit and three study visits. During these visits, a blood sample will be taken and you will be asked to complete questionnaires about you physical fitness and quality of life. You will also be asked to wear a Holter monitor for 48 hours in order to count the number of PVCs and PACs you have daily. In addition to these assessments, you will also complete an exercise stress test during your screening visit.
Investigation of the Changes of Brain Structure and Function in Premature Ejaculation Patients and...
Premature EjaculationLifelong premature ejaculation (LPE) is a common male sexual dysfunction with a high prevalence in global. Up to now, the etiology of LPE remains unclear. In recent years, dapoxetine, a highly potent serotonin-transporter inhibitor, has been used for treating premature ejaculation. However, the underlying mechanism of dapoxetine was unknown. Recently, with widespread use of neuroimaging techniques, like positron emission tomography and magnetic resonance imaging (MRI) in basic science, researchers can acquire human data on cerebral base of human sexual behavior, not only in normal subjects but also in patients with sexual dysfunction. Therefore, in order to further understand the biological mechanism of LPE and the brain targets of dapoxetine, the present study would investigate the brain changes of LPE and the effect of dapoxetine on brain activation by using MRI technology.
