Filter by:This study will maximize identification of women with Lynch Syndrome using an enhanced screening strategy to identify those at risk. These women will be referred to genetic counselling for testing and those found to have Lynch Syndrome will be asked to invite first degree relatives to participate and undergo genetic testing for Lynch Syndrome. Screening guidelines and risk reducing surgery options for participants found to have Lynch Syndrome will be reinforced by the study and adherence to these guidelines will be assessed annually for ten years following Lynch Syndrome diagnosis to assess the impact and cost-effectiveness of this enhanced screening approach.
Obstructive sleep apnea (OSA) syndrome affects up to 5% of the general population. The prevalence is multiplied by 13 in coronary artery disease (CAD) patients. Many studies have shown that OSA syndrome was the main risk factor for cardiovascular morbidity and mortality (RR = 9.1 [95%, 2.6 to 31.2]). If the value of treatment with Continuous Positive Airway Pressure (CPAP) in symptomatic CAD patients (daytime sleepiness and/or 2 clinical symptoms with Apnea Hypopnea Index (AHI) ≥ 20) appears to be established, treatment with CPAP in asymptomatic CAD patients (with AHI> 30) may be too demanding. Alternative treatments are rare and results are highly variable. Therefore, it would be interesting to suggest other treatment modalities with moderate coronary and/or minimally symptomatic OSA syndrome.
Guillain-Barré syndrome (GBS) is an immune-mediated polyneuropathy that usually follows an antecedent infection and causes acute neuromuscular paralysis. GBS is currently classified into the two major subtypes: a classical demyelinating type and axonal variant type. Whereas in Europe and North America demyelinating GBS is the major subtype, in East Asia and Central and South America, axonal GBS is found in 30~65% of patients. Although the pathophysiology of GBS has not been fully understood, major advances have been made in understanding the pathophysiology particularly for the axonal form of GBS. It is now established that axonal GBS is caused by molecular mimicry of human gangliosides by the Campylobacter jejuni lipo-oligosaccharides. Autoantibodies bind to GM1 or GD1a at the nodes of Ranvier, activate complements, and disrupt sodium channel clusters and axo-glial junctions, resulting in the nerve conduction failure and muscle weakness. C. jejuni infection induces production of antibodies, which cross-react with gangliosides on the human nerve axolemma, and activate the complements, resulting in formation of membrane attack complex (MAC). The pathology leads to axonal degeneration. The standard treatments for GBS are plasma exchange and intravenous immunoglobulin and the disease progression reaches its nadir within 4 weeks. However, during the acute phase, 18-28 % of the patients require artificial ventilation and 4.1-6.3 % of the patients die of complications. Recovery takes several months or years, and 16.7-19.7 % of the patients still require aid to walk one year after onset. Because of such serious disability of GBS patients, an alternative novel therapy that can prevent death during acute phase or severe sequelae is needed. Eculizumab is a humanized monoclonal antibody of murine anti-human C5 antibody and specifically binds to the final activation complement component C5 and inhibits MAC formation by suppressing the cleavage reaction of C5 into C5a and C5b. The efficacy of eculizumab against GBS has been shown in a model of axonal GBS. At present, there are no animal models of demyelinating GBS. However, autopsy studies have shown that C3d and C5b-9 (MAC) are deposited on the Schwan cells, and therefore eculizumab can be effective also for demyelinating GBS. This clinical trial will be conducted to investigate the efficacy and safety of eculizumab for GBS to warrant future global clinical trials. Moreover, we also study the relationship between the efficacy and clinical subtypes of GBS, such as axonal or demyelinating form. Our trial will provide insights on whether the future global developmental plan should target the whole spectrum of GBS world-wide or focusing on Asia and South America.
This study in patients with IBS-C is a randomized, double-blind, placebo-controlled, parallel-group clinical trial with 12 weeks of study drug therapy.
A Single-Dose, Open-Label, Extension Study to Evaluate the Sustainability of the Effects of SYN-010 in Patients with Irritable Bowel Syndrome with Constipation
The purpose of this study is to evaluate the efficacy and safety of HE10 eye drop for the patients with moderate to severe dry eye syndrome.
The objectives of this randomized controlled trial are to compare insulin sensitivity following true acupuncture + placebo metformin (Group 1) vs sham acupuncture + placebo metformin (Group 2) vs sham acupuncture + metformin (Group 3) in women with PCOS and IR.
This is a study protocol for a multicenter, randomized, and controlled trial. In this protocol, we present a randomized controlled trial comparing acupuncture pretreatment followed by letrozole vs letrozole alone in polycystic ovary syndrome (PCOS) women with anovulatory infertility. The high prevalence of insulin resistance (IR) in women with PCOS women is considered to be one of the major pathophysiological changes of PCOS, leading to anovulatiory infertility. A study has shown that electro-acupuncture could significantly improve insulin sensitivity. The effect of acupuncture pretreatment on anovulatory PCOS women followed by ovulation induction has not been investigated before. A total of 384 patients enrolled in this study will be randomized into one of two groups. The treatment group: a 16 week acupuncture pretreatment followed by 4 cycles of letrozole and the control group: 4 cycles of letrozole alone. The primary outcome is the live birth rate. We postulate that acupuncture pretreatment followed by letrozole results in a higher live birth rate when compared with letrozole alone.
The acute respiratory distress syndrome(ARDS)has a high morbidity and mortality in patients admitted to intensive care units(ICUs). It represents a significant public health issue. No large nationwide, multicenters study of ARDS has been conducted in China. The purposes of this study are to analyse: 1)the incidence and outcomes of ARDS in ICU; 2) factors associated the mortality ; and 3) risk factors for development of ARDS .
Three hundred women with severe premenstrual syndrome will be divided into 3 groups using computer generated random numbers. Group 1 will receive COC containing drospirenone (drospirenone 3mg+Ethinylestradiol 0.03mg; Yasmin® ScheringAG, Egypt) daily for 21 days starting from the 3rd day of menstruation in addition to oral fluoxetine 20 mg daily. Group 2 will receive COC containing drospirenone daily for 21 days starting from the 3rd day of menstruation in addition to a daily oral placebo similar in size, color and structure to fluoxetine . Group 3 will receive oral placebo similar to COC daily for 21 days starting from the 3rd day of menstruation in addition to a daily oral placebo similar in size, color and structure to fluoxetine.
