NCT ID: NCT03647826 Completed - Clinical trials for Mental Health Wellness 1

Mind Power - A CBT Based Program for Adolescents

Start date: September 1, 2018
Phase: N/A
Study type: Interventional

The purpose of this study is to strengthen school achievement and positive mental health, and to prevent and reduce school dropout and mental distress among high school students. The researchers will scale up techniques that have already been proven highly effective in preventing common mental disorders (depression, anxiety) in high risk groups (indicated and selective prevention). The researchers will disseminate these techniques to entire first year classes of high school students irrespective of risk factors (universal prevention). The study will report whether universal delivery in school of "Mind Power" - a Cognitive Behaviour Therapy (CBT) based programme - will strengthen school grades, self-efficacy, self-esteem, self-regulation, mental perceptions and well-being, and prevent and reduce school dropout, and symptoms of anxiety and depression. In addition the researchers will analyse whether such universal delivery prevents more mental distress, and is more cost-effective than when it is delivered only to those at high risk for school failure, dropout, or mental distress.

NCT ID: NCT03099954 Completed - Hypertension Clinical Trials

Withings Pulse Wave Velocity and Blood Pressure Study

Start date: January 19, 2017
Phase: N/A
Study type: Observational

Measure pulse wave velocity stability in relation to time of day, day of the week, physical activity, sleep quality, stress levels and blood pressure.

NCT ID: NCT01645566 Completed - Mental Stress Clinical Trials

Task Focusing Strategy During a Simulated Cardiopulmonary Resuscitation

Start date: December 2007
Phase: N/A
Study type: Interventional

This is a prospective randomized controlled study. The aim of this study is to 1. describe the stress patterns experienced during a CPR situation; 2. investigate whether the perceived stress was associated with CPR performance in terms of hands-on time and time to start CPR; 3. to investigate whether this task focusing strategy reduces perceived stress levels, and 4. whether this translates into better CPR performance. Based on findings that clear, directive leadership can enhance performance in cardiac resuscitation, we further 5) investigate if stress was associated with fewer leadership statements.

NCT ID: NCT01396330 Completed - Diabetes Mellitus Clinical Trials

Effect of Mental Stress on Glucose Control in Patients With Diabetes Mellitus

EMSOD
Start date: September 2011
Phase: N/A
Study type: Interventional

Introduction Stress is part of the investigators daily life, and means to cope with it allow adaptation and survival. To this end, physiological pathways are activated, including neuroendocrine, cardiovascular and metabolic responses. In short term, the majority of consequences are beneficial, in the long run, however, chronic psychosocial stress may constitute an increased risk for coronary heart disease, type 2 diabetes, and disability. Acute mental stress induces an exaggerated release of stress hormones e.g. catecholamine and cortisol which are thought not only to increase heart rate (HR) and blood pressure (BP) but also to increase blood glucose levels. In clinical practice, patients and health care providers are often confronted with questions concerning psychological stress as a possible reason for glucose fluctuations. Whether stress itself or poor treatment adherence is responsible for the altered glucose control remains often controversial. Differences in the inter- and intraindividual response to stress have been suggested, but only a few small studies have addressed the effect of acute psychological stress on glucose control in patients with diabetes. Patients with type 2 diabetes may overestimate the effect of acute psychological stress on glucose control but further studies are clearly needed to definitely exclude or confirm a relevant effect of stress on the glucose control in diabetic patients. For example, effects of longer lasting or repetitive events of psychological stress on glucose concentrations still remain elusive. The aim of the present study was therefore to investigate the effect of prolonged psychological stress by means of repetitive safe driving training courses on glucose control in patients with diabetes. Patients and Methods Forty patients with type 1 or insulin-treated type 2 diabetes attending the outpatient-clinic of the Kantonsspital Frauenfeld or University Hospital of Zurich for regular visits are invited to participate. Included are patients on any oral glucose-lowering treatment and at least one daily injection of insulin, a valid driver license and written informed consent given. Exclusion criteria are diabetes duration <2 years, pregnancy, unstable coronary artery disease, limited visual acuity or unstable proliferative diabetic retinopathy, uncontrolled hypertension (BP >160/95mmHg) and pituitary or adrenal disease. The Ethics committee of the Kanton Thurgau approved the protocol and the study conform to the principles outlined in the Declaration of Helsinki. Study protocol Each patient completes a control and a stress testing day which takes place consecutively in a randomized order. Randomization is performed by an uninvolved third person. The study is carried out at the driving training area of the Touring Club Switzerland at Hinwil. Patients are advised to have lunch before 12:00 a.m. and to abstain from food thenceforth. Drinking mineral water remains allowed during the entire study days, and the patients have to take their basal insulin and other medication as usual. Patients are advised to arrive at the driving training area between 2:30 and 3:00 p.m. At arrival, a capillary glucose measurement is carried out, and glucose concentrations ≥10mmol/l are corrected with short-acting insulin analogues (glucose target 6 - 8mmol/l). Subsequently, no additional adjustment with insulin is allowed during the study. Glucose concentrations ≤4mmol/l are always corrected with administration of 10g carbohydrate (DextroEnergy® or orange juice). On both study days, patients ingest a standard meal at 4:45 p.m. (i.e. 15min before the driving training). Immediately after the meal, short-acting insulin is injected in knowledge of the carbohydrate content (same dose on both days) or oral antidiabetics are ingested as usual. Measurements of capillary and plasma glucose concentration, blood pressure, heart rate, stress perception and salivary cortisol concentration are carried out in regular intervals between 4 and 9 p.m. on both study days. On the control day, patients are placed in a quiet room and are permitted to read. They also have the possibility to leave the room and stay on a balcony. On the stress testing day, patients complete a driving training with their car between 5 and 7 p.m. The driving training consists of 3 consecutive exercises: first, a slalom track on dry and wet asphalt, secondly, a full braking exercise with water obstacles. Thirdly, the car is hurled around by a mechanical plate and the patients has to regain control over it.
