Combined oral contraceptive pills (COCs) are the most commonly used hormonal form of birth control in the United States with at least 87% of women of reproductive age reporting oral contraceptive use at some point in their lives (9). Despite their frequent use, [more...] the six and twelve month discontinuation rates for oral contraceptive pills are 31 and 47 % respectively (17), with common reasons for discontinuation attributed to the side effects of abnormal bleeding, headache, and weight gain. Additionally, COCs are contraindicated in certain groups of women as outlined by The Centers for Disease Control Medical Eligibility Criteria (11). Given the high prevalence of oral contraceptive users who commonly discontinue use secondary to side effects or who are not eligible for use as a result of underlying health conditions, the development of novel oral non-hormonal methods that are equally effective at pregnancy prevention are warranted. This current study aims to evaluate the effect of an FDA approved drug, Cilostazol, on human oocyte maturation. Such a study has not been conducted to date. If Cilostazol demonstrates an ability in humans to affect resumption of meiosis, then this non-hormonal agent could be uses as a possible contraceptive agent in the future. This knowledge would have profound reproductive health implications. The investigators propose that women undergoing treatment with the FDA approved dose of 100mg PO every 12 hours of Cilostazol will demonstrate an impairment of egg maturation in comparison to paired historic controls following ovarian follicle stimulation.

1. ERCP is a commonly performed endoscopic procedure used to treat stones and blockages of the bile duct as well as to manage leaks which occurs following laparoscopic gallbladder removal. [more...] 2. Post ERCP pancreatitis (PEP) complicates 5-15% of biliary endoscopic procedures and results in considerable suffering and cost. 3. Patients with acute pancreatitis are treated with fluids. 4. Our aim is to assess whether prophylactic treatment with aggressive intravenous hydration prevents ERCP pancreatitis. 5. In a blinded fashion patients will be randomized to aggressive intravenous versus moderate hydration during and aftere ERCP for standard clinical indications. Our hypothesis is that prophylactic treatment with aggressive intravenous hydration protects against ERCP pancreatitis.

The purpose of this study is to learn if women taking the atazanavir and ritonavir have lower levels of a birth control medication called norethindrone. Norethindrone (also called the mini pill) is an FDA (Food and Drug Administration) approved progestin-only birth [more...] control pill used to prevent pregnancy. Norethindrone is the standard medication used in women who take the progestin only pill to prevent pregnancy. There are other birth control pills which contain different medications. The investigators want to learn if HIV medications (atazanavir and ritonavir) make the blood level of this birth control pill higher or lower. If the levels of norethindrone are too low it may not work to prevent pregnancy. The investigators also hope to learn about changes in the vaginal fluids and cervical fluids when women are taking this birth control pill.

Movement disorders such as dystonia, hypertonia, and spasticity interfere with or prevent voluntary movement. Studies have suggested that using biofeedback to increase awareness of muscle activation can improve motor function in patients with motor deficits. The investigators hypothesize that [more...] the daily use of a surface electromyographic (SEMG) biofeedback device for one month will improve motor function in children and young adults with dystonia, hypertonia, and/or spasticity. The SEMG biofeedback device is worn over the muscle(s) the subject has difficulty in controlling and provides vibratory feedback about muscle activation. Groups of children and young adults (ages 3-21), with dystonia, hypertonia, and/or spasticity will be asked to wear a small (approx 1 square inch) sensory feedback device on their affected muscle(s) for 5 hours a day for one month. The device will vibrate and emit a blue light when the muscle is activated. At the start of the experiment, subjects will be tested on the Goal Attainment Scale (GAS), the Pediatric/Adolescent Outcomes Data Collections Instruments (PODCI), and the Barry Albright Dystonia Scale (BAD). For one month, subjects will practice goals without device. After a month, subject will be assessed again and be given device to practice goals for a month. After one month, the subjects will be tested on the outcome measures again and return device.

This study is about rehabilitation of arm function after a stroke. The investigators are testing the dosage of therapy that is needed for meaningful recovery of arm and hand function. Dosage of therapy refers to the amount of time (in this case, the [more...] total number of hours) that a person participates in treatment. The investigators hope to learn how much therapy time is needed in order for change to occur in arm and hand function after a person has had a stroke. Eligible candidates must have had a stroke affecting the use of an arm or hand at least 6 months ago.

HIV positive pregnant women who receive potent combination antiretroviral therapy over at least the last trimester of pregnancy, and who have proper obstetric interventions and are able to avoid breast feeding, decrease the risk of having an infected infant to about 1%. [more...] Breast milk HIV-1 RNA (cell free) viral load is significantly associated with breast milk transmission, and a 2-fold increased risk of transmission associated with every 10-fold increase in breast milk viral load has been reported. In addition, cell associated virus (HIV DNA) was associated with a significant increase in risk of transmission independent of the level of cell-free viral RNA. However, multiple studies of HIV positive women giving birth have shown that exclusive breast-feeding carries a much lower risk of HIV transmission than mixed breast-feeding (defined as breast milk along with complementary food, other milk, and/or infant formula). The proposed study will measure the ARV drug etravirine concentrations in blood and breast milk in postpartum HIV positive women on HAART therapy. The short-term goal is to determine how much etravirine penetrates into breast milk, and whether it leads to undetectable HIV viral load in the breast milk and therefore has the potential to decrease the risk of transmission of HIV through breast milk. The long term goal is to see if breast milk HIV levels can be lowered sufficiently to prevent maternal to child transmission (MTCT) of HIV in infants receiving only breast feeding in resource poor areas.

This study is being done to test whether taking testosterone can prevent loss of muscle mass and strength due to anterior cruciate ligament (ACL) reconstructive surgery. Testosterone is the principal male sex hormone and an anabolic (muscle promoting) steroid. It is essential [more...] for the development of male reproductive tissues and promotes increased muscle, bone mass, and the growth of body hair. The investigators hope to learn whether testosterone given before and after ACL reconstructive surgery will increase muscle mass and strength and potentially improve recovery time following surgery.

Stroke is the second leading cause of death and the leading cause of adult disability worldwide. This investigation will address the safety and feasibility of directed, intra-arterial Magnesium measurement and therapy, through endovascular access, in acute stroke patients. The [more...] proposal represents the first study to directly quantify levels of a systemically administered neuroprotectant in the region of cerebral ischemia. It also establishes a novel endovascular platform for direct delivery of neuroprotective agents to ischemic cerebral tissue distal to an occlusive thrombus. This research seeks to improve patient care by establishing a novel delivery mechanism for the rescue of threatened brain parenchyma that can be administered rapidly following acute stroke. If successful, this selective distribution will allow delivery to "at risk" tissue in a rapid manner. Salvage of viable, but threatened, penumbral tissue could afford stroke patients an increased probability of favorable long term outcome. The investigators hypothesize that endovascular, intra-arterial, Magnesium administration will deliver high concentration of this neuroprotective agent to otherwise inaccessible cerebral territories, while limiting systemic concentrations. The proposed investigation will evaluate the safety and feasibility of this novel treatment technique

Patients with liver disease frequently present to the hospital with bleeding from dilated veins in their foodpipe (called esophageal varices). The current standard of care is to perform endoscopic variceal ligation (placing rubber bands around the varices through an [more...] endoscope)in patients presenting with bleeding varices. Patients generally receive ligation at the time they come in with bleeding and then return at regular intervals to have repeat ligation in order to eradicate the varices. However there have been no studies to determine the appropriate intervals for esophageal variceal ligation until eradication. We will conduct a randomized comparison of 1-week vs. 2-week intervals for esophageal ligation in patients that have presented with bleeding varices. Our hypothesis is that one-week ligation will achieve more rapid eradication than the two-week interval with a greater proportion of patients achieving variceal eradication at 4 weeks after the index bleeding episode.

The formation of intraperitoneal adhesion following abdominal surgery is accepted by clinicians as an inevitable consequence. More than 90% of patients undergoing a surgical procedure in the abdomen will develop intraperitoneal adesions. The incidence however, of small bowel obstruction [more...] (SBO) resulting form these adhesions is far lower. To date, it is unknown which risk factors predispose these patients to develop SBO. Several have been proposed, such as age, peritonitis, or surgery for small bowel injury resulting from gunshots. None of them however, has been widely accepted. During the last 20 years the significant lifetime risks associated with this phenomenon and its impact on the quality of life of patients has been well recognized. In addition, the burden on healthcare resources due to complications caused by adhesions is increasing and medicolegal consequences are rapidly evolving. Early SBO following laparotomy for trauma is a poorly described entity. A few retrospective, single institution studies with a low number of patients have tried to address this issue. However, these studies either included a subset of trauma patients, i.e. patients sustaining penetrating trauma, or patients undergoing a negative or non-therapeutic laparotomy, or examined only the incidence of SBO requiring surgical intervention. In addition, recent data regarding this issue is lacking, especially after the implementation of the damage control concept and the other advances in trauma surgery. The aim of this study is to define the incidence of early SBO following laparotomy for trauma and to examine possible risk factors associated with its development.

The proposed project takes an innovative approach to childhood obesity prevention, for which there currently no evidence-based programs, and for which results of current trials have produced mainly short-term or disappointing effects. The aim of this project is to adapt and [more...] revise parts of two nationally recognized programs for drug prevention for use with children in grades 4-6 with the express purpose of obesity prevention. The current study will attempt to promote emotion regulation, neuro-cognitive function, and social competence in order to prevent obesity. A total of 24 elementary schools from two of the largest districts in Orange County will be randomly assigned to either the obesity prevention program or control group (N=3460 4th grade students and their parents). A cohort of students will be followed from the 4th through 6th grades. Intervention students will be administered the Pathways obesity prevention program by trained teachers. The population is ethnically diverse (36% white, 57% Hispanic, 6%Asian; 48% on free/reduced lunch programs). Self-report measures, BMI, and waist circumference will be administered at the beginning of 4th grade, and at end of 4th , 5th , and 6th grade. Teacher, administrative, and parent surveys will be administered on the same schedule to measure school environment. Program implementation will be measured by teacher self-report and research staff observations. Data will be analyzed with statistical approaches that capture effects of school and classroom, test the theoretical model of change, and evaluate developmental trends in mediators and outcomes across the three grades. Findings should be generalizable to most elementary schools, and will be used to develop evidence-based program standards for childhood obesity prevention.

Endovascular repair of infrarenal abdominal aortic aneurysms (AAA) requires a contrast agent to identify the vascular anatomy and placement of the stent graft. Iodine contrast has traditionally been used, but has the potential to harm the kidneys. Another contrast agent [more...] is carbon dioxide gas. It has been proven safe to use, but the quality of the images it creates needs to be compared to iodine contrast. Patients in this study undergo the endovascular AAA repair as they normally, with the iodine contrast. At the end of surgery carbon dioxide gas contrast is given as an extra step. The images will be later evaluated.

A. HYPOTHESES: In older men low testosterone levels, abdominal obesity and elevated fasting insulin who are at risk for the cardiovascular complications such as heart attack and stroke. 1. Supplemental testosterone will decrease abdominal [more...] fat (visceral adominal adipose tissues (VAT), subcutaneous abdominal adipose tissue (SAT), and hepatic fat) and intramyocellular lipid in peripheral muscles(IMCL). 2. Supplemental testosterone will improve insulin sensitivity by: 1. Decreasing hepatic glucose output (HGO), a measure of central insulin resistance 2. Decreasing VAT 3. Decreasing SAT 4. Increasing adiponectin production 5. Improving peripheral glucose disposal (Rd) by reducing IMCL 6. Increasing appendicular skeletal muscle mass and basal metabolic rate B. OBJECTIVES: 1. Primary Objective: To determine the effects of supplemental testosterone to achieve testosterone levels in the upper normal physiologic range on central adipose tissue (abdominal VAT, SAT, and hepatic fat) and peripheral skeletal muscle fat (IMCL and intermyocellular fat). 2. Secondary Objectives: To determine the effects of supplemental testosterone to achieve testosterone levels in the upper normal physiologic range: 1. on hepatic glucose output (HGO) and peripheral glucose disposal (Rd) 2. on hepatic glucose synthesis from glycogen, glycerol and the Krebs cycle using [1,6-13C2C] glucose, D2O, and [U-13C3] palmitate isotope dilution studies 3. on adiponectin and apoprotein B levels 4. on basal metabolic rate (REE, R/Q) as related to changes in skeletal muscle mass Results of this study will provide greater understanding whether androgen therapy enhances insulin sensitivity by decreasing HGO, decreasing adiponectin production, improving peripheral Rd and if these desired effects are achieved, whether they are due to reductions in VAT, SAT, liver fat, IMCL or effects of augmenting muscle mass per se. Results will generate hypotheses to investigate cellular and molecular mechanisms of androgen effects in persons at risk for the Metabolic Syndrome.

Posterior tibial tendon dysfunction (PTTD) is the most common cause of painful and debilitating acquired flatfoot deformity in adults. The dysfunction is often progressive and may result in attenuation of the PTT and eventually collapse of the plantar arch or even [more...] rupture of the tendon. Current therapeutic management of PTTD is multipronged and includes management with foot orthoses, stretching, and strengthening exercises. Evidence drawn from research related to the management of painful chronic Achilles tendinosis suggests that eccentric strengthening of the posterior tibialis may lead to superior results compared to concentric. The purpose of this research is to determine the effectiveness of treatment interventions used in the management of PTTD.
