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.

Gait and Balance in Thoracolumbar Spinal Deformity
Spinal CurvaturesSurgical intervention may provide pain relief and improvement in function but one area of significant clinical interest is the restoration/improvement in gait and functional balance. Based on the investigators knowledge, there is limited literature on biomechanics and neuromuscular control of the lower extremities and spine as assessed by objective gait analysis and balance strategies in adult degenerative scoliosis patients, pre and post surgical intervention. The purpose of this study is to determine the impact of spinal deformity on the biomechanics and neuromuscular control of the lower and upper extremities, and also investigate the impact of surgery on these functions as evaluated by gait and balance analyses using dynamic EMG, video motion capture and force plate analysis and also to compare these patients with healthy controls to better evaluate the extent of limitations before and after surgery.
Cardiopulmonary Exercise Testing to Evaluate Pulmonary AVMs With and Without Airflow Obstruction...
Pulmonary Arteriovenous MalformationsHereditary Hemorrhagic Telangiectasia2 morePulmonary arteriovenous malformations (PAVMs) are a rare vascular condition affecting the lungs. PAVMs lead to low blood oxygen levels, yet are very well tolerated by patients. This study will examine the exercise capacity of PAVM patients using formal cardiopulmonary exercise tests performed on a stationary bicycle, and whether this is affected by the presence of concurrent airflow obstruction, such as due to asthma.
Single Versus Dual Spine Attending Surgeons in Complex Adult Deformity Surgery:
ScoliosisUnspecifiedTwo recent studies showed that having two attending spine surgeons performing complex adult spine deformity surgery instead of one, decreased complications, unplanned surgeries within 30-days [Ames], 90-day readmissions, wound infection, pulmonary embolism/deep vein thrombosis and post-operative neurologic complications [Sethi]. However, both studies were retrospective and did not evaluate any cost-savings associated with having two spine surgeons instead of one performing complex spine deformity surgery. Most cost-effectiveness studies have used traditional accounting (TA) methods to determine costs. A few cost-effectiveness studies have used time-driven activity-based costing (TDABC) [Kaplan] in medicine [Au, Balakrishnan] and none in spine surgery. Objectives: The objectives of the study are (1) to determine if dual spine attendings reduce downstream costs compared to a single spine attending for complex spine surgeries using traditional accounting methods; and (2) to demonstrate an application of the TDABC method to evaluate the operating room phase during complex adult spinal deformity surgery and compare it to traditional accounting methods (TA).
Clonidine for Tourniquet-related Pain in Children
Polydactyly ToeThumb Hypoplasia30 moreThis study is designed as a randomized, placebo-controlled, double-blinded, clinical trial with two parallel groups. This study investigates the association between a single dose of the drug, Clonidine, and the total amount of opioid administered under and 24 hours after surgery in children undergoing orthopedic limb surgery with the use of tourniquet. The investigators hypothesize that administration of clonidine to children undergoing limb surgery with the use of inflatable tourniquets would reduce post-procedural pain. This study is a pilot to obtain an effect size. Based on this the investigators will calculate a sample size for the main trial enabling us to reach a power of 0.8 with a significans level of 0.05.
Effect of Oral Propranolol on mRNA Expresssion in Symptomatic Cavernous Malformation
Cerebral Cavernous MalformationsThis is a single center, randomized, trial that will enroll twenty (n=20) patients with a diagnosis of symptomatic cavernous malformations who are planned candidates for surgical resection by one of the investigators, and who meet all of the inclusion and exclusion criteria. Patients will be randomized into two groups: A Treatment group of ten (n=10) patients that will receive oral propranolol at a dose of 60mg per day (one 60mg ER capsule per day) for 7- to 10-days prior to surgery plus their usual medications, and a Control group of 10 (n=10) patients will receive only their routine medications. Currently, the only active treatment alternative for symptomatic cerebral cavernous malformations is surgery. A control group is required to allow for a semi-quantitative comparison with mRNA and miRNA levels in the treatment group.
