NCT01619098
Hospital readmissions are common, costly, and potentially preventable. They are also potentially responsive to health system interventions. However, it is uncertain which components of care transition interventions are efficacious, for which populations, and at what cost. This randomized controlled study is part of a larger project that will evaluate a three-tiered quality improvement (QI) intervention intended to reduce hospital readmissions within 30 days post-discharge from an urban safety net hospital that serves a racially and linguistically diverse population (the randomized controlled study evaluates Tier 3). Few studies have evaluated care transition interventions to reduce readmissions among low-income, diverse patient populations, and the accumulated evidence on the effects of these multi-faceted interventions on readmission rates has been inconclusive. This project will take advantage of a unique sequence of three QI innovations to reduce hospital readmissions implemented beginning in 2007 in an integrated safety net health care system. The "discharge-transfer" tiers are as follows: 1) Tier 1 includes a comprehensive, individualized home care plan (HCP) reviewed by the medical service floor nurse with the patient prior to discharge; 2) Tier 2 adds the electronic transmission of the HCP to the patient's primary care medical home where, on the business day following discharge, a Registered Nurse makes an outreach telephone call to the discharged patient to confirm comprehension of the HCP and to address medical questions or needs; 3) Tier 3 further adds a community health worker, the Patient Navigator, to participate in bedside discussions to develop rapport and learn about patients' home situations, weekly outreach calls to assess patients' needs and to facilitate communication between the patient and the primary care team, and reminder calls to patients prior to all medical appointments to eliminate barriers to outpatient follow-up. The Aim of the study being registered is to evaluate the effects of an ongoing randomized natural experiment on readmissions, health care use, adherence to medication instructions, and preparedness for discharge. This natural experiment features random assignment to one of two QI interventions, Tier 2 or Tier 3, and exclusively targets patients at high risk for readmission, those with one or more of the following risk factors for readmission: discharge diagnosis of congestive heart failure or COPD; length of stay \> 3 days; age \> 60; or previous hospitalization within the past six months. The investigators hypothesize that the Patient Navigator intervention (Tier 3) compared to usual care (Tier 2) will increase the rates of 30-day post-discharge PCP visits; reduce 30-day hospital readmission rates; and reduce the total number of days in hospital in the 180 days following the index admission for high risk patients. The investigators further expect that the PN intervention will improve patient adherence to medication instructions in the HCP and reduce the probability of reported problems with post-discharge care.

NCT01963364
Some carbohydrates (complex sugars) which are found in grains, fruit and vegetables, cannot be digested by humans. When eaten they pass through the small bowel to the large bowel, or colon. Some bacteria that live in the colon are able to digest these carbohydrates, and use them as an energy source. This releases energy that humans can absorb, and may have other effects on health as well. The process also releases gases such as hydrogen and methane into the colon, which will eventually be released as flatulence. There is some evidence in animals, and humans, that changing the carbohydrate content of the diet may increase the numbers of bacteria in the colon that can use this energy source. Recent work has looked at how changes in colon bacteria and carbohydrate in the diet affect transit, the speed at which food and stool moves through the stomach and bowels. This undergraduate project will use techniques in Magnetic Resonance Imaging developed in Nottingham to investigate how a prolonged change in dietary carbohydrate might affect speed of transit through the bowel and gas production in the colon, and whether there is any evidence of a change in the level of signalling chemicals that may affect bowel function.

NCT01586533
This double-blind, randomized, comparator-controlled Phase II study is designed to establish the safety and efficacy of Zoenasa Rectal Gel compared to mesalamine enema in subjects with left-sided ulcerative colitis, as measured by the modified ulcerative colitis disease activity index (UCDAI), over 6 weeks of treatment. In this study, two cohorts of subjects will receive either Zoenasa-1:4 (1.0g NAC; 4.0g 5-ASA) investigational drug enema therapy or comparator mesalamine enema (4.0g 5-ASA). The study will enroll subjects randomized equally into the 2 cohorts. Each cohort will enroll approximately 60 subjects. The two arms of the trial will be enrolled concurrently in a randomized fashion.
NCT01645319
The primary objectives of the study are: 1. To compare the proportion of patients who achieve a successful response to treatment (reduction in Intraocular Pressure (IOP) of \>15%) between patients treated with laser surgery (including argon laser trabeculectomy, and selective laser trabeculoplasty) with patients receiving additional medications, at 1-year post-treatment initiation. 2. To compare the proportion of patients who achieve a successful response to treatment (reduction in IOP of \>15%) between patients treated with other procedures (including incisional surgery, drainage device procedures, and other glaucoma procedures) with patients receiving additional medications, at 1-year-post-treatment initiation. The study is a prospective, observational cohort study and will not provide or recommend any treatment. Patients who have failed initial medical therapy with two glaucoma medications will be identified and enrolled at the time of scheduling of a laser surgery procedure or other procedure such as incisional surgery or drainage device, or initiation of an additional course of therapy with medication as determined by their physician. This inception cohort of new initiators of laser surgical treatment, other procedures, or additional medical therapy will be followed for 12 months. All decisions regarding treatment are solely at the discretion of the physician in accordance with their usual practice. Enrollment is expected to begin in February 2011 and continue through 12 months of follow-up after enrollment targets have been reached.
NCT01693003
Exercise intolerance is a major complain of patients with chronic obstructive pulmonary disease (COPD). Dynamic hyperinflation has been recognized as an important limiting factor responsible for the appearance of intolerable dyspnea during exercise. Regular treatment with long-acting bronchodilators promotes a more sustained reduction of hyperinflation and consequent symptom relief and increase in the patient's ability to overcome physical demands of daily life. Tiotropium bromide (TIO) is a new generation, long-acting anticholinergic bronchodilator that significantly improves lung function, reduces symptoms and improves exercise tolerance in patients with advanced COPD. Indacaterol is a new ultra-long duration (\>24 h) β2-agonist, which promotes sustained dilation of the bronchi with a once-daily administration. Compared to tiotropium, indacaterol provides evidence that is as effective as tiotropium for bronchodilation, as well as other clinical outcomes such as dyspnea and state of health. However, comparative effects of indacaterol versus tiotropium with regard to outcomes in tolerance, dyspnea and dynamic lung hyperinflation during exercise is scarce. We hypothesized that indacaterol and TIO are not different in terms of exercise tolerance and its determinants (dynamic hyperinflation and dyspnea).
NCT01752361
The purpose of this study is to describe gastrointestinal (GI) motility in patients suffering from severe Ulcerative Colitis (UC) and to compare these results with similar results from a study on healthy subjects. Both studies are done with the use of Motilis 3D-Transit system which consists of a small electronic capsule ingested and detected by a receiver carried by the patient. Position and orientation of the capsule are interpreted by dedicated computer software and transit times, progression velocity and contraction frequencies can be revealed. The study is mainly descriptive and is designed to test and evaluate the usefulness of the Motilis 3D Transit system in UC patients and to tell us more about GI motility during severe inflammation. Motilis 3D-Transit system gives us a unique chance to study the gastrointestinal canal as a whole during severe illness. We expect to include 20 patients suffering from severe UC admitted to Hospital with the purpose of getting medical treatment. We do not expect any drop out, but in case of drop out a new patient will be included.

NCT02018432
Main adverse events of Roflumilast are weight loss, loss of appetite, insomnia, headache, diarrhea, vomiting, and nausea. Although the majority of these adverse reactions were mild or moderate. They occurred mainly at the beginning of therapy and mostly resolved with continued treatment around for two weeks according to experiences of clinicians. These adverse events occur more often in Roflumilast 500 μg than 250 μg, having negative impact on compliance of patients at the early stage of treatments. Thus, investigators aim to compare the drop-out rates between the usual dosage (Roflumilast 500 μg once daily) and the dose escalation (Roflumilast 250 μg once daily for 4 weeks and then escalating dose of 500 μg once daily).
NCT01797653
Randomized controlled trial (therapeutic vs. placebo CPAP) including 46 patients with obstructive sleep apnea (OSA) to define the physiological effects of continuous positive airway pressure (CPAP) therapy withdrawal on myocardial perfusion and dermal and renal microvascular function during a 2 week period.
NCT02016638
Hypothesis:Sleep Disorders are very common during pregnancy but the their exact role in causation of pregnancy related disorders is yet to be determined. OSA can complicate pregnancy given the risk factors of weight gain, upper displacement of the diaphragm, and hormonal-induced hyperaemia of the nasopharyngeal passages. SDB confers the risk of hypertensive disorders of pregnancy and is associated with adverse maternal and foetal outcomes. The study would involve pregnant females which would be prospectively followed in pregnancy and post partum to know the prevalence of sleep disorders in pregnancy. Diagnosis of sleep disorders would be confirmed by overnight polysomnography and ambulatory blood pressure monitoring. Pregnancy outcomes, both maternal and fetal would be recorded and its relation with sleep disorders in pregnancy would be analysed.
