NCT ID: NCT03797794 Recruiting - COPD Clinical Trials

Influence of PESF on Oxygen Saturation, Quality of Life and Exercise Capacity in COPD

Start date: January 2019
Phase: N/A
Study type: Interventional

The effect of PESF (Pulsating Electrostatic Field) on the oxygen saturation, quality of life and the exercise capacity will be studied in a randomized, dubbel blind, placebo-controlled parallel design with 32 COPD patients GOLD III and IV with a oxygen saturation below or equal to 90%. The patients will be treated with three 30-minute PESF- or placebo-sessions distributed over 5 days. Directly before the first session, oxygen saturation, quality of life (CCQuestionnaire), exercise capacity (6-MWT and grip strength) and phase angle (BIA) will be measured and compared to the results directly after the third session. Oxygen saturation is also monitored during 24 hours after each session.

NCT ID: NCT03795831 Recruiting - Clinical trials for Intraoperative Hypotension

Validation Study in Patients of a Non-invasive Blood Pressure Monitor for Perioperative Use

Start date: March 1, 2017
Study type: Observational [Patient Registry]

Collecting all available data (waveforms, beat to beat data, status data) generated by a non invasive blood pressure monitor on each hand and compare this to the actual data obtained by intra arterial (radial) monitoring. This to see if the non invasive bloodpressure monitor can be validated for intraoperative use.

NCT ID: NCT03793946 Not yet recruiting - Quality Improvement Clinical Trials

A Digital Antimicrobial Stewardship Smartphone Application to Combat AMR: the AB-assistant

Start date: September 2019
Phase: N/A
Study type: Interventional

Optimal prescribing of antimicrobials is becoming increasingly challenging because of the growing complexity of guidelines and constantly changing distribution of infectious pathogens. Prescribing antimicrobials appropriately according to local guidelines optimizes therapy for the individual patient and reduces the emergence of resistance. By adapting and evaluating a smartphone based app containing local guidelines we aim to study appropriate prescribing of antimicrobials by physicians in three hospitals (Netherlands, Sweden and Switzerland).

NCT ID: NCT03793790 Recruiting - Chronic Pain Clinical Trials

The Role of Learning in Nocebo Hyperalgesia

Start date: September 20, 2018
Phase: N/A
Study type: Interventional

Nocebo effects are adverse effects induced by patients' expectations. Nocebo effects on pain may underlie several clinical conditions, such as chronic pain. These effects can be learned via classical conditioning mechanisms. In the lab, nocebo effects are commonly studied via conditioning with continuous reinforcement (CRF) during which 100 percent of unconditioned pain stimuli are paired to conditioned stimuli (i.e., the activation of a mock medical device). Partial reinforcement (PRF) provides a more uncertain pairing during conditioning, where less than 100 percent of unconditioned pain stimuli are paired to conditioned stimuli. This method provides a potentially more clinically relevant learning platform to study how nocebo effects on pain are induced. In this study, the efficacy of conditioning with PRF, CRF, and sham-conditioning in inducing nocebo effects on pain will be compared. Furthermore, a counterconditioning method will be compared to an extinction method for the attenuation of nocebo effects on pain. Given the relevance of nocebo effects for patients, it is important to ascertain effective & clinically relevant methods to understand how nocebo effects may be formed and attenuated. This study is conducted by Leiden University.

NCT ID: NCT03793777 Not yet recruiting - Cognitive Function Clinical Trials

The Effect of Aronia With and Without Guarana Extract on Cognitive Function

Start date: January 14, 2019
Phase: N/A
Study type: Interventional

There is a great interest in improving cognitive performance, including memory and attention. Improved attention is desirable for a large group of people because it is linked to improved performance . Students and professionals can benefit from improved attention and thus performance in academic and other work environments. In addition, cognitive functioning also plays an important role in sports. Various cognitive skills, including attention, reaction time and motor function, have shown that they can influence sport performance. A completely natural supplement with aronia melanocarpa (and guarana) extract could be a promising way to naturally improve cognitive performance.

NCT ID: NCT03791320 Recruiting - Clinical trials for Coronary Artery Disease

Fast Assessment of STenosis Severity- FASTII Study

Start date: October 15, 2018
Study type: Observational

The Multicenter FAST (Fast Assessment of STenosis severity) study is a prospective observational multicenter study designed to evaluate the diagnostic accuracy of offline 3D-QCA based FFR, using CAAS Workstation (Pie Medical Imaging, Maastricht, the Netherlands) in identifying hemodynamically significant coronary artery disease with pressure wire-based FFR (≤0.80) as the reference standard.

NCT ID: NCT03791138 Recruiting - Breast Cancer Clinical Trials

The Impact of a Web-based Patient Decision Aid for Women Considering Breast Reconstruction

Start date: August 16, 2017
Phase: N/A
Study type: Interventional

This study evaluates the impact of an online patient decision aid on the process of decision making regarding breast reconstruction and the decision quality in women with breast cancer undergoing mastectomy and considering immediate breast reconstruction. Half of participants will receive care as usual and access to the online decision aid, while the other half will receive care as usual including a standard information leaflet.

NCT ID: NCT03789136 Recruiting - Cachexia; Cancer Clinical Trials

The Effect of Colon Cancer on Muscle Gene Expression, Body Composition, Muscle Function, and Muscle Metabolism

Start date: February 24, 2017
Study type: Observational

Rationale: Cancer cachexia is a complex metabolic syndrome characterized by clinically relevant loss of muscle mass with or without loss of fat mass. To determine how treatment methods can be most effective, full insight in changes in gene expression, body composition, muscle function and muscle metabolism are of great importance. Objective: Main aim of the study is to investigate the differences in gene expression, body composition, muscle function and muscle metabolism in colon cancer patients compared to controls. Study design: Observational study Study population: 40 colon cancer patients undergoing a tumor resection (30 primary tumor and 10 liver metastases) and 15 control patients undergoing an inguinal hernia repair (♂, 10) or an abdominal hysterectomy (♀, 5). Main study parameters/endpoints: Primary study parameter will be gene expression (transcriptomic and polymerase chain reaction analyses of muscle biopsies). Secondary parameters will be body composition (determined in available CT scans and bio impedance analysis and with DEXA), muscle function parameters (grip and knee flexion/extension strength and measured in a biopsy), metabolic markers (measured in fat and muscle biopsies), biochemical markers (measured in blood/serum) and gene expression of fat biopsies. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: The investigators expect no additional risk for the subjects due to the proposed measurements. Biopsies will be taken during the planned operation and therefore is not expected to cause a significant increase in burden for the patient. All other measurements are non-invasive, observational measurements with no risk of any harmful side effects.

NCT ID: NCT03787108 Recruiting - Clinical trials for Non-Alcoholic Fatty Liver Disease

Measuring Fatty Liver With Ultrasound and MRS in Children With Overweight or Obesity

Start date: December 24, 2018
Study type: Observational

Obesity is associated with a variety of comorbidities, amongst which non-alcoholic fatty liver disease (NAFLD). A recent meta-analysis has shown that the prevalence of NAFLD in obese pediatric populations is around 35%, compared to approximately 8% in general pediatric populations, making it a very important health threat in these populations. The golden standard for diagnosis of NAFLD is liver biopsy. However, since liver biopsy is associated with a certain risk of morbidity and mortality, this method is inappropriate for screening large populations at-risk for developing NAFLD. Magnetic resonance spectroscopy has demonstrated excellent correlation with liver biopsy and the is the most accuratete non-invasive method to measure liver fat content in children. However, MRS is expensive and not available in all centres. A novel ultrasonographic measurement to quantitatively assess liver steatosis is the hepatorenal index (HRI). Previous studies have shown high sensitivity and specificity of the HRI, as compared to MRS and liver biopsy. However, this measurement has never been validated in children. In this study, the HRI will be compared to MRS in children with obesity, to validate the HRI and to determine cut-off points.
