NCT ID: NCT02961465 Completed - Surgery Clinical Trials

Effectiveness and Safety of Sacral Neuromodulation in Patients With Idiopathic Slow-transit Constipation

Start date: February 2, 2018
Phase:
Study type: Observational

Rationale: Previous reviews showed that the evidence regarding the effectiveness of sacral neuromodulation (SNM) in patients with therapy-resistant, idiopathic (slow-transit) constipation is of suboptimal quality. Furthermore, there is no estimate of costs and cost-effectiveness in this patient group. Study design: A prospective cohort study with one group. This study is conducted next to a randomized controlled clinical trial (RCT) on 'the effectiveness and cost-effectiveness of sacral neuromodulation in patients with idiopathic slow-transit constipation refractory to conservative treatments' (for more information ClinicalTrial.gov ID: NCT02961582). This RCT is part of a temporary reimbursement arrangement, called conditional reimbursement of health care (in Dutch: Voorwaardelijke Toelating) of the National Health Care Institute (Zorginstituut Nederland). As part of this arrangement, the Ministry of Health, Welfare and Sports requires that SNM remains available for eligible patients during the conditional reimbursement period, also when inclusion of the RCT has ended. Furthermore, the Ministry requires that patients who received personalized conservative treatment in the RCT (control group), are offered SNM after completion of their follow-up of 6 months. As a result, the National Health Care Institute requires that the patients who receive SNM outside the RCT are included in a prospective cohort study to be able to collect data on them. Aim: The aim of this prospective cohort study is to collect more (but uncontrolled) information regarding the safety and effectiveness of SNM. Study population: Adolescent (14-17 years) and adult (18-80 years) patients with idiopathic slow-transit constipation refractory to conservative treatment. Intervention: The intervention is SNM, a minimally invasive surgical procedure consisting of two phases. In the screening phase an electrode is inserted near the third sacral nerve and connected to an external stimulator. If the screening phase is successful (average defecation frequency (DF) ≥3 a week), the electrode is connected to a pacemaker that is implanted in the buttocks of the patient. If not successful, the pacemaker will be removed and patients receive conservative treatment. Main study parameters/endpoints: The primary outcome is treatment success at 6 months, defined as an average DF of ≥3 a week according to a 3-week defecation diary and safety. Secondary outcomes are straining, sense of incomplete evacuation, constipation severity and generic (health-related) quality of life ((HR)QOL).

NCT ID: NCT02960334 Completed - Atrial Fibrillation Clinical Trials

Screening for Actionable Atrial Fibrillation During Preoperative Consultation With the MyDiagnostick

Start date: November 2016
Phase: N/A
Study type: Observational

Atrial Fibrillation (AF) It is the most common arrhythmia in the world. It carries great public health significance because of its prevalence, additional morbidity and mortality. It provides a 4-5 times higher risk of developing a ischemic stroke or transient ischemic attack. In term, this risk can be 70% reduced by taking oral anticoagulants. Actionable AF is the overarching term for silent AF (asymptomatic AF) and undertreated AF (known AF, but not sufficiently protected against ischemic stroke). It is recommended that over the age of 65, patients should be screened with pulse palpation or rhythm strip for the presence of AF. The MyDiagnostick is a single-lead I, compact hand-held device that analyses heart rhythm during one minute. During preoperative consultation, this device will be used to value the yield of screening for actionable AF.

NCT ID: NCT02959814 Completed - Clinical trials for Coronary Artery Disease

Diagnostic Accuracy of On-line Quantitative Flow Ratio (QFR). FAVOR II Europe-Japan

FAVOR II EJ
Start date: February 22, 2017
Phase:
Study type: Observational

Quantitative Flow Ratio (QFR) is a novel method for evaluating the functional significance of coronary stenosis. QFR is assessed by calculation of the pressure in the vessel based on two angiographic projections. The purpose of the FAVOR II study is to evaluate the diagnostic accuracy of on-line QFR compared to 2D Quantitative Coronary Angiography (QCA) with FFR as gold standard.

NCT ID: NCT02959203 Completed - Clinical trials for Pneumothorax Iatrogenic Postprocedural

Comparison of Bedside Ultrasound With Chest X-ray for Confirmation of Central Venous Catheter Position

COMBUX
Start date: June 2016
Phase: N/A
Study type: Observational

Background: Insertion of a central venous catheter (CVC) could lead to a variety of complications. To detect those complications, Chest X-ray (CXR) is still the reference standard. However, there are major limitations in performing CXR's in the critical care setting. Aim/objectives: The objective of this study is to compare the use of bedside ultrasound (US) to conventional CXR in visualization of accuracy and safety of the CVC placement. The aim is to eventually replace X-ray with bedside ultrasound as gold standard for the confirmation of CVC-placement in critically ill patients, thereby reducing radiation exposure and unnecessary delay before CVC use. Methods: The bedside US will be performed by the student or attending physician, who is blinded for CXR findings. After US examination, the attending physician (or student) will fill in a structured form, based on an established protocol. CXR will be performed before or after US examination and assessed by a radiologist. The radiologist will be blinded for the findings of the bedside ultrasound to prevent any biases. Final diagnosis will be determined after examination of the complete medical chart.

NCT ID: NCT02959099 Completed - Atherosclerosis Clinical Trials

Incident COronary EveNts Identified by Computed Tomography

ICONIC
Start date: July 20, 2012
Phase:
Study type: Observational

The Incident COronary EveNts Identified by Coronary Tomography (ICONIC) trial is a nested, case-control study derived from the dynamic CONFIRM registry, and is based on propensity scoring methods to match subjects with (cases) or without (controls) acute coronary syndrome (ACS). Our primary objective is to determine CCTA-based atherosclerotic plaque characteristics that would help elucidate precursors of incident ACS, with the secondary objective being an analysis of gender-specific disparities.
