8 Clinical Trials for Various Conditions
Cannabis is the most commonly used drug by women during pregnancy with an estimated prevalence of use in Colorado of 5.7%. THC and its metabolites freely cross the placenta and blood-brain barrier to bind with cannabinoid receptors, disrupting the endogenous cannabinoid signaling system during a critical period of development of cortical circuitry structure and function. The density of cannabinoid receptors in the developing brain is high, especially in the limbic areas and prefrontal lobes. Research in animal models suggests synaptic plasticity in the prefrontal lobes as well the amygdala and hippocampus are impacted by the prenatal cannabis exposure; regions associated with both cognitive and emotional control, thus influencing long-term deficiencies in attention and impulsivity. This pilot study will collect preliminary data on the structural impact of in utero cannabis exposure on region-specific morphology and structural connectivity of white matter tracts that connect to the prefrontal lobes and the limbic regions shortly after birth, before confounding by the postnatal environment becomes a major influence.
The purpose of this study is to help scientists understand why some people who were exposed to alcohol in the womb have special facial features but other people do not. This study will test if genetics (or DNA) explains these differences. We hope this will help improve treatments and interventions for people with fetal alcohol spectrum disorders (FASD). Participants in this study (or their parents or legal guardians) will be asked to: * Answer some questions about themselves. These questions ask about their demographic background (such as gender, race, ethnicity, income, and education), their health history, and their mother's health during her pregnancy with them (if that information is known). * Speak with study staff briefly by phone or video chat to confirm enrollment in the study and ask any questions they have. * Take photographs of their face. * Provide a saliva sample for genetic research. Participants can complete the study at home from anywhere in the world. The questions can be answered online, over the phone, or on paper. Adopted families are welcome to enroll. The study pays for all shipping costs.
This is a multi-country, prospective safety study of pregnant women exposed to efgartigimod or efgartigimod PH20 SC any time within 25 days prior to conception or any time during pregnancy. Women exposed to efgartigimod or efgartigimod PH20 SC only during breastfeeding will also be eligible to enroll. Background rates of major congenital malformations (MCMs) will be obtained from populations within the same countries/regions as the countries/regions in which the efgartigimod or efgartigimod PH20 SC exposed pregnancies were reported.
The main objective of the study is to compare the maternal, fetal, and infant outcomes of pregnant women who are exposed to vonoprazan during pregnancy with outcomes of an internal comparison cohort of pregnant women who are unexposed to vonoprazan during pregnancy but who may be exposed to other products for the treatment of conditions for which vonoprazan may be prescribed.
This is a Phase 4 observational study designed to assess the impact of Palynziq ® (pegvaliase) treatment in pregnant women with PKU and on their offspring who were exposed to pegvaliase at any time during pregnancy and breastfeeding.
The hypothesis of this study is that maternal and fetal biologic variation in the balance between pro-inflammatory and anti-inflammatory mediators can be measured by currently available techniques. In addition, the investigators hypothesize that a pro-inflammatory maternal phenotype increases the risk of fetal exposure to intrauterine hyperthemia and inflammatory cytokines; and that intrapartum events, especially known risk factors for fever at term such as epidural analgesia and prolonged rupture of membranes, may interact with underlying maternal factors to increase fetal exposure to inflammatory cytokines. This experiment aims to establish the first large-scale cohort to evaluate biomarkers for maternal and fetal inflammation in term pregnancy and to elucidate the relative antepartum and intrapartum contributions to fetal inflammation.
The purpose of the study is to evaluate fetal, maternal, and infant outcomes through 12 months of age.
The purpose of this study is to determine whether choline supplementation can improve cognitive functioning of children with prenatal alcohol exposure.
