NCT01335087
OSA may be a modifiable risk factor for cardiovascular disease due to its association with hypertension, stroke, heart attack and sudden death. The standard therapy for symptomatic OSA is continuous positive airway pressure (CPAP). CPAP has been shown to effectively reduce snoring, obstructive episodes and daytime sleepiness and to modestly reduce blood pressure and other risk factors for cardiovascular disease. The overall aim of ISAACC is to determine if CPAP can reduce the risk of heart attack, stroke or heart failure for people with OSA admitted in a hospital for an acute coronary syndrome. Overall objective: To assess the impact of obstructive sleep apnea (OSA) and its treatment on the clinical evolution of patients with acute coronary syndrome (ACS). Primary objectives: 1\. To determine if continuous positive airway pressure (CPAP) treatment will reduce the rate of cardiovascular events (cardiovascular (CV) death, non-fatal events (acute myocardial infarction (AMI), non-fatal stroke, hospital admission for heart failure, and new hospitalizations) for unstable angina or transient ischaemic attack (TIA)) in patients with ACS and co-occurring sleep apnea. Secondary objectives: 1. Determine the prevalence of OSA in patients who have suffered an episode of ACS. 2. Other secondary objectives will include the effects of CPAP on: * To evaluate a composite of CV death, myocardial infarction (MI) and ischaemic stroke. * Components of primary composite endpoints * Re-vascularization procedures * To evaluate all-cause death * To evaluate new onset, ECG-confirmed atrial fibrillation or other arrhythmias * To evaluate newly diagnosed diabetes mellitus, according to standard definitions * To evaluate OSA symptoms (Epworth Sleepiness Scale (ESS)) * To evaluate quality of life in patients with ACS (Test EuroQol (EQ-5D). 3. To establish the relationship between the severity and phenotype of patients with OSA and clinical outcomes of ACS. 4. To establish the relationship between CPAP compliance and CV events incidence. 5. To identify biological risk markers that allow us to establish the most important mechanisms involved in cardiovascular complications in these patients. 6. To conduct a cost-effectiveness analysis of the diagnosis and CPAP treatment of patients with ACS who have obstructive sleep apnea.

NCT02050529
Severe Hypertension in pregnancy demands urgent treatment because of high mortality \& morbidity in obstetric patients. Hydralazine, the most commonly used agent, causes sudden hypo tension and tachycardia. Labetalol because of combined α and β blocking effects lacks these side effects. Most recent Cochrane systematic review on use of anti hypertensive drugs in pregnancy related hypertension, could include only four trials of comparison of Hydralazine with Labetalol. Three out of total 4, had sample size ranging from 20-60 obstetric, with total sample size ranging from 19-30. Only 2 trials reported severe persistent hypertension.This review could not conclude about comparative effects due to insufficient data and suggested that further trials should compare Hydralazine with Nifedipine or labetalol, and to report severe persistent hypertension and adverse feto-maternal effects. OBJECTIVES:1) To compare efficacy and severe persistent hypertension after intravenous Labetalol versus Hydralazine, within maximum 5 drug boluses, in obstetric severe hypertensive patients at Civil Hospital Karachi. 2\) To compare immediate adverse maternal and fetal effects in the study group. 3) Furthermore, to assess response to treatment, in terms of patient and disease characteristics. STUDY DESIGN: Randomized controlled trial. SETTING \& DURATION OF STUDY: Gynaecology Unit I, Civil hospital Karachi, from Oct 2012 to Sep 2014 METHODS: Total one hundred eighty-four patients with, severe hypertension (systolic blood pressure(S.B.P)≥160 and/or diastolic blood pressure(D.B.P) ≥110 mm Hg) at greater than 28 weeks of pregnancy or upto 72 hours after delivery, were enrolled and randomly allocated to drug A or B. At enrollment, 94 patients were allocated to Labetalol to 96 to Hydralazine through simple randomization. Since six cases were excluded due to insufficient information( 2 from group A and 4 from group B) so finally data of 92 patients in each group was analyzed. Primary outcome measures were lowering of S.B.P to \<160 mm Hg and D.B.P \<110 mm Hg (efficacy)and severe persistent hypertension. In addition maternal hypo tension, tachycardia, bradycardia, adverse effect on fetal heart, still birth and neonatal bradycardia were measured. EXPECTED OUTCOME: Efficacy, severe persistent hypertension and side effects of Labetalol versus Hydralazine, in our population were determined. Assessment of response to Drug A and B, will help in choosing a drug for different patient and disease characteristics.
NCT03722056
Gastric GISTs are rare neoplasms that require excision for cure. Although the feasibility of laparoscopic resection of gastric GIST less than 2cms has been established, the feasibility, safety and long-term efficacy of these techniques for larger lesions are unclear. Investigators hypothesized that laparoscopic resection of gastric GISTs even for larger lesions is feasible \& results in low perioperative morbidity and an effective long-term control of the disease.
NCT02241434

NCT02468869
The goal of the proposed study is to assess the potential of information structuring for improving discharge communication. Specifically, the investigators aim to examine the advantages of an information-structuring skills training for physicians (compared to an empathy skills training) on discharge communication and associated patient outcomes, such as patients' information recall and adherence to physician recommendations. The investigators hypothesize that patients receiving structured discharge information from their trained physicians will be able to recall more information and show higher adherence to recommendations relative to controls (i.e., patients receiving discharge information from doctors trained in empathy skills).
NCT01504646
The primary aim of this study will be to evaluate the effects of Lyprinol® supplementation on airway inflammation and the bronchoconstrictor response to dry air hyperpnea in individuals with asthma. The investigators hypothesize that Lyprinol® supplementation, compared to placebo, will significantly attenuate airway inflammation and hyperpnea-induced bronchoconstriction in asthmatic individuals.

NCT01602679
The rapidity with which progesterone slows LH (and by inference GnRH) pulse frequency in women is unclear. The investigators hypothesize that progesterone slows LH pulse frequency within 10 hours. The investigators propose to assess this further with a randomized, cross-over, placebo-controlled study. Regularly cycling women without hyperandrogenism will be admitted to the Clinical Research Unit on cycle day 5-9 (mid-follicular phase) for a 10 hour frequent sampling study to observe LH, FSH, estradiol, progesterone, and testosterone. Either oral micronized progesterone suspension or placebo will be administered at 0900 h. During a subsequent menstrual cycle, subjects will undergo another study identical to the first except that oral progesterone will be exchanged for placebo or vice versa in accordance with a crossover design.
NCT02675517

A secondary objective is to evaluate the patient¿s general condition (physician¿s evaluation) at visit 1 (baseline visit at the start of the study) and at visit 2 (final visit at the end of the study, approx. 6 weeks after visit 1), as well as patient satisfaction with Spiolto® Respimat® at visit 2.
NCT02786927
This is a Phase IV multi-center, randomized, open-label, cross-over, placebo study in subjects with Chronic Obstructive Pulmonary Disease (COPD) to compare inhaler-specific preference attributes of two inhalers - ELLIPTA dry powder inhaler (DPI) and the HANDIHALER DPI. The primary objective of this study is to evaluate whether more subjects with COPD prefer the ELLIPTA inhaler to the HANDIHALER DPI based on the number of steps needed to take medication. All subjects will use the ELLIPTA inhaler and the HANDIHALER inhaler in the corresponding treatment periods based on the randomisation scheme, and at the end of 2 periods, complete the inhaler preference questionnaire. Subjects will self-administer the inhalation once daily for 5-9 days in each treatment period. This study will be placebo-only, and neither inhaler will contain active treatment. Subjects will continue their current COPD medication(s) as prescribed, and will follow up with their regular physician for their COPD healthcare during the study. Approximately 211 subjects will be enrolled in the study. ELLIPTA is a trademark of the GlaxoSmithKline group of companies. HANDIHALER is a trademark of Boehringer Ingelheim International GmbH.

NCT01985750
Dyspnoea is the uncomfortable shortness of breath that debilitates millions of patients with lung disease, heart failure and cancer. It is often very difficult to treat. The sensations of dyspnoea are processed in the brain, and we believe that psychological factors modify and amplify these sensations, frequently exacerbating symptoms. This study aims to identify the importance of learning in the brain mechanisms of dyspnoea by investigating a cohort of patients with chronic breathlessness undergoing pulmonary rehabilitation . Pulmonary rehabilitation is a six-week course of exercise, education and group therapy that improves dyspnoea but does not improve lung function. This leads us to hypothesise that some of the beneficial effects of PR maybe due to changes in brain processing, potentially relating to a learning effect. Therefore to probe whether learning is important in the beneficial effects of pulmonary rehabilitation, we intend to modify learning with the drug d-cycloserine. D-cycloserine is an antibiotic that enhances learning due to its effects at N-methyl D-aspartate (NMDA) receptors in the hippocampus. Our previous study in a similar group of patients demonstrated the importance of the hippocampus in breathlessness perception, and we now wish to investigate this in more depth. The study involves collecting physiological, psychological and clinical measures on in conjunction with brain scanning, before, during and once after pulmonary rehabilitation. Subjects will either receive d-cyloserine or placebo before the first four pulmonary rehabilitation sessions.
