Vascular Effects of Hesperidin in Metabolic Syndrome
Endothelial DysfunctionMetabolic SyndromeIt has been suggested that cardiovascular risk factors either independently or in cluster (metabolic syndrome) increase the risk of both type 2 diabetes (DM2) and cardiovascular diseases (CVD). Consumption of citrus fruits is linked to reduced cardiovascular morbidity and mortality. Hesperidin is a flavanone abundant in citrus fruit with putative vasodilator actions in vitro. While molecular mechanisms of vascular actions of hesperidin begin to be explored, no data on in vivo vascular effect of this flavanone has been ever acquired.

Portable Monitoring Device for the Diagnosis of Sleep Apnea in Patients With Chronic Obstructive...
Chronic Obstructive Pulmonary DiseaseObstructive Sleep Apnea SyndromeIntroduction: The prevalence of overlap between Chronic Obstructive Pulmonary Disease (COPD) and Obstructive Sleep Apnea Syndrome (OSAS) is around 10%. This overlap syndrome is an important issue because is related to nocturnal desaturation and its complications. The use of portable monitoring devices (PM) for the diagnosis of OSAS was recently accepted as an alternative to full-night polysomnography (PSG). However, there are not studies evaluating the PM recording in COPD patients to detect or exclude OSAS. Objective: To evaluate if a PM (Stardust®, Respironics, Inc, USA) could accurately measure the apnea-hypopnea index (AHI) in COPD patients with a suspicion of OSAS.

PURPOSE: This clinical trial is studying T cells to see how well they help in predicting acute graft-versus-host disease in patients undergoing donor stem cell transplant.

The International Collaborative Exfoliation Syndrome Treatment Study
Exfoliation SyndromeGlaucoma1 morePurpose: To determine the efficacy of treatment with latanoprost in combination with pilocarpine versus timolol or timolol/dorzolamide fixed combination (Timoptic or Cosopt) in eyes with XFS and elevated intraocular pressure (IOP). Methods: This is a randomized, open-label study to test the hypothesis that improving both pressure-dependent and pressure-independent aqueous outflow and minimizing iridolenticular friction will interfere with the progression of XFS, allow improvement in trabecular function, and be more effective over time than simply reducing aqueous formation. Randomization was performed across the centers, per patient rather than per eye to avoid any crossover effect caused by aqueous suppressants. Group I was treated with latanoprost and pilocarpine, both in the evening, and Group II with Timolol or Cosopt b.i.d. Only one eye per patient was randomized. Patients were followed for 2 years with assessment of IOP, visual field progression, tonographic outflow coefficient and trabecular pigmentation at the 6:00 and 12:00 position.

The Effect of Human Albumin Infusion on VEGF Levels in Women at Risk for Ovarian Hyperstimulation...
Ovarian Hyperstimulation SyndromeThis research study was designed to look at the effect of human albumin transfusion on circulating levels of Vascular Endothelial Derived Growth Factor (VEGF), a protein that is believed to be responsible for the syndrome of ovarian hyperstimulation. Patients have been asked to participate because they are identified as at risk for the Ovarian Hyperstimulation Syndrome (OHSS), a potentially serious complication of in vitro fertilization. It has been established that the onset of OHSS may be preventable by the infusion of albumin at the time of egg retrieval; however, we do not know by what mechanism albumin works. As we know the pathogenesis of OHSS is related to VEGF released from the ovaries, we believe human albumin may serve to "bind up" this VEGF and prevent it from causing its harmful effects. The purpose of this study is to evaluate the effect of albumin infusion on blood and urine VEGF levels in these patients.

Comparison of Biofeedback vs. Botox Injection to Treat Levator Ani Syndrome
Levator Ani Syndrome With Pain and/or Constipation Symptoms.Purpose: To assess whether EMG directed biofeedback therapy or Botulinum toxin type A injection of the levator ani muscles has any effect on pain from the levator ani syndrome, and, in addition, to what extent either treatment is superior to the other in terms of anorectal physiologic measurements, and quality of life. Study Design: Randomized, prospective, unblinded double-armed study with crossover. Methodology: Female subjects, aged 18 and over, with painful levator ani muscle spasm for at least one month duration will be randomized to receive either biofeedback therapy or Botulinum toxin type A injection. After randomization they will all undergo visual analog pain scoring, anorectal manometry, colonoscopy (if clinically indicated), and self-reported SF-36 quality of life measurement. Each patient will also complete numerical pain scale scoring, an SF-36, and a satisfaction questionnaire at each treatment visit and follow-up visit. Patients will submit these by mail. Identification numbers will be assigned to each subject for use on the SF-36 and Satisfaction Questionnaires throughout the study. Subjects will again undergo anorectal manometry at the end of their treatment arms. In the biofeedback arm patients will be treated biweekly for up to eight treatments and be provided exercises to practice at home based on their muscle function noted during the biofeedback training session. Subjects will keep a treatment diary of the exercises they do at home to help ensure compliance with the protocol. In the Botulinum toxin injection arm patients will be treated with scheduled injections of the levator ani muscles every six weeks for up to three total injections of 100U each. These injections will be directed to the painful areas of the levator muscles as guided by physical exam and EMG measurements. Should any patient fail their initial randomized treatment assignment (failure defined as "very dissatisfied" or "dissatisfied" on the satisfaction questionnaire), they will then be allowed to cross over to the other study arm. In addition to numerical pain scale scoring, an SF-36 questionnaire and anorectal manometry will also be repeated at the time of crossover. We intend to include all randomized patients in the final data analysis (according to their originally assigned treatment arm), regardless of outcome or reason for dropout, thus making this an "intent-to-treat" analysis. Pivotal Study Definitions: The definition of adequate pain reduction, for the purposes of data analysis, will be a reduction in a subject's mean pain score of two on a numerical pain scale (0-10). Failure of either therapy will be defined as a response of "very dissatisfied" or "dissatisfied" on the satisfaction questionnaire at the end of either biofeedback (eight treatment visits) or Botulinum toxin (three injections) both before and after crossover. Outcomes: We will determine the following for biofeedback therapy and Botulinum toxin type A injection: mean pain reduction, any differences in anorectal physiologic measurements (such as mean resting anal sphincter pressure), any changes in self-reported quality of life, and overall patient satisfaction.

Carpal Tunnel Syndrome and Static Magnetic Field Therapy
Carpal Tunnel SyndromeThe purpose of this Phase II study is to assess the feasibility of conducting a large scale trial which will evaluate the effectiveness of static magnetic field therapy as a treatment for Carpal Tunnel Syndrome. This preliminary study will determine which of three strength magnets to use in the future. Participants will be recruited from three primary sources. 1) Patients with a possible diagnosis of Carpal Tunnel Syndrome who have been referred to the Orthopaedic and Rehabilitation Clinics of OHSU for Nerve conduction studies. If after conducting these studies a potential participant shows evidence of mild to moderate Carpal Tunnel Syndrome s/he will be informed about the study and invited to participate in additional screening. B) Patients seen at the National College of Natural Medicine (NCNM) Clinics who have a clinical diagnosis of Carpal Tunnel Syndrome will be informed about the study and invited to enter the screening process for further eligibility. C) Participants will also be recruited from the general public including staff and students at OHSU and NCNM). Eligibility will be determined through a stepwise process including telephone screening for general eligibility, Nerve Conduction screening for electrodiagnostic eligibility, and Boston Carpal Tunnel Questionnaire screening for symptom severity eligibility. Those potential participants who meet all eligibility requirements will be randomized to one of three magnetic field dosages. They will be provided with a ¾" diameter x 1/8" thick magnet which they will be required to apply for six weeks during the hours of sleep. Over the course of the study participants will have four visits to the General Clinical Research Center of OHSU and three visits to the Orthopaedic and Rehabilitation Clinics of OHSU for Nerve Conduction studies to be performed by either Dr. Nels Carlson or Dr. Hans Carlson. Questionnaires to be completed during the course of the study include a general health information and demographics questionnaire, the Boston Carpal Tunnel Questionnaire, which will be completed on six occasions, a general symptoms checklist and a Post Treatment Participant satisfaction questionnaire. Recruitment, retention, compliance and safety will be analyzed using descriptive statistics. Effectiveness of the three different strength magnets will be assessed by comparing participants' baseline scores on the Boston Carpal Tunnel Questionnaire with their scores after six weeks of magnet use.

Genetics and Clinical Characteristics of Bardet-Biedl Syndrome
Bardet-Biedl SyndromeThis study will evaluate patients with a rare inherited condition called Bardet-Biedl syndrome . The purpose of the study is to learn more about the genetics and clinical characteristics of this disorder. Patients may have the following problems: polydactyly (extra fingers and toes); retinal dystrophy (changes in the retina that may lead to vision problems, including blindness); obesity and diabetes (overweight and high blood sugar due to failure of body organs to respond to insulin); cognitive dysfunction (difficulties with learning and understanding); hypogenitalism (decreased functioning of the ovaries in women and the testes in men); kidney anomalies (changes in the structure or function of the kidneys); heart disease; and hepatic fibrosis (liver disease). Patients with Bardet-Biedl syndrome may be eligible for this study. First-degree relatives will also be enrolled for certain tests and procedures. Candidates are screened with a review of their medical records, laboratory tests, and x-rays. Patients in this study undergo the following tests and procedures: Medical and family history and physical examination, including body measurements. Blood tests to evaluation kidney, liver, heart, and hormonal function, and for genetic studies and other research purposes. Dual emission x-ray absorptiometry (DEXA) scan to measure the amount of total body fat. For this test, the subject lies on a table for scanning with low-dose X-rays. Computed tomography (in adults) of the abdomen to measure abdominal fat. CT uses a small amount of radiation to obtain images of internal body structures. Magnetic resonance imaging (in children) of the abdomen to measure abdominal fat. MRI uses a magnetic field and radio waves to obtain images of internal body structures. Oral glucose tolerance tests to measure blood glucose and insulin levels. For this test, the patient drinks a glucose (sugar) solution. Blood samples are drawn through an IV catheter before the test begins and at 1, 2, and 3 hours after drinking the solution. Complete eye examination to look for retinal changes and to assess vision, and, if medically needed, an examination of the ear, nose, and throat to check for hearing and breathing abnormalities. Tests of learning ability in patients over 5 years of age. For younger patients, a parent is asked about the child's development. Ultrasound study of the ovaries and uterus in females and of the testes in males. Photographs of the face, hands, feet, body, and genitalia, if the patient agrees. Meeting with investigators and a genetic counselor for review of test findings when the studies are completed. Relatives of patients have a complete medical and family history and physical examination. Blood is drawn for assessment of kidney, liver, heart, and hormonal function and for genetic study and other research purposes. Relatives over 5 years of age may have tests of learning ability and cognition. For younger patients, a parent is asked about the child's development. Relatives meet with investigators and a genetic counselor for review of test findings when the studies are completed.
