NCT ID: NCT03764644 Terminated - Clinical trials for Generalized Anxiety Disorder

Web-based Attention Bias Modification Treatment for Childhood Anxiety Disorders

Start date: October 2013
Phase: N/A
Study type: Interventional

Anxiety disorders are the most common childhood psychiatric disorders, with prevalence rates as high as 15% to 20%. Success rates of the first choice treatment strategy (i.e. Cognitive Behavioural Therapy; CBT) are around 50%. Non-response increases the risk for other psychiatric disorders, school dropout, social isolation, alcoholism, and suicide attempts. These negative consequences endorse the urgent need to develop more effective and accessible treatments that enhance effectiveness of current treatment options. A promising new treatment for childhood anxiety disorders is Attention Bias Modification Treatment (ABMT). ABMT is based on evidence that anxiety-disordered individuals selectively allocate their attention toward threatening information (i.e. attention bias). This bias in early and automatic attention processes starts a cascade of subsequent biases in information processing and memory, resulting in heightened anxiety. Attention bias is an underlying mechanism of anxiety. Thus ABMT, which implicitly trains individuals to attend away from threatening information should alleviate anxiety. In contrast to ABMT, CBT explicitly targets later stages of information processing that are under volitional control. Meta-analyses of studies in adults have shown that ABMT indeed results in increased recovery rates and clinically significant changes in anxiety, compared to so-called "sham" attention training (control condition). Imaging studies have shown that ABMT modifies lateral prefrontal cortex activity to emotional stimuli. Despite its promising results, fewer studies have examined ABMT in anxiety-disordered children. The aim of this trial is to enhance treatment effectiveness by combining web-based ABMT with CBT in a large sample of anxiety-disordered children. The primary aim is to compare ABMT-augmented CBT with CBT as monotherapy on recovery rates for anxiety disorders and changes in anxiety. The secondary aim is to compare ABMT with sham attention training on anxiety disorder recovery rates and changes in anxiety. We hypothesize that (1) ABMT-augmented CBT will result in a significantly better treatment success than CBT alone, and (2) ABMT will result in a significantly better treatment success than sham attention training. The design will be a randomized, double-blind, sham-controlled clinical trial.

NCT ID: NCT03658200 Terminated - Pulmonary Disease Clinical Trials

Fully Automated Scan Technique Optimisation of Scan Timing in Chest CT

Start date: April 5, 2018
Phase: N/A
Study type: Interventional

Computed Tomography Angiography (CTA) is a non-invasive imaging tool widely used for various indications. Contrast media (CM) is used to enhance the intravascular lumen and organ parenchyma, depending on the indication. Recent technical advances in CT scan techniques allow for a very fast scan acquisition with substantially increased image quality in terms of temporal and spatial resolution. However, with faster scan acquisition, challenges arise with regard to CM bolus timing. The risk of outrunning the CM bolus in these fast acquisitions is higher, resulting in a decreased intravascular attenuation and subsequent hypothetical increase in non-diagnostic image quality. Previous studies have investigated the reduction of CM volume. When reducing the CM volume, the total injection time decreases and the window of peak enhancement shortens and becomes more narrow. The latter increases when injecting small CM volumes with higher flow rates. Although the peak enhancement increases, the window of peak enhancement decreases more rapidly. Thus, when administered with the same flow rate, the peak of the enhancement curve will be lower, narrower and faster compared to larger CM volumes. This, in combination with the faster scan acquisition makes the timing of the start of the scan highly important, since scanning at the peak enhancement is necessary to achieve a diagnostic image quality. New bolus tracking auto-delay software (Fully Automated Scan Technique, FAST, Siemens Healthineers) automatically estimates the delay needed to scan at the peak of the enhancement curve. With help of this software, the optimal individual scan delay and enhancement can be achieved, and the risk of non-diagnostic scans should decrease. Therefore, this study aims to evaluate the performance of the Bolus Tracking Auto-Delay (FAST) software in patients receiving a standard chest CT with regard to the number of non-diagnostic scans (< 300 HU) and compare this with standard care (manual set pre-scan delay).

NCT ID: NCT03616639 Terminated - Pain Clinical Trials

Neurotoxic Adverse Effects of Morphine and Oxycodone for Pain in Terminal Patients With Diminished Renal Function

Start date: June 4, 2018
Phase: Phase 4
Study type: Interventional

Significant pain is a common condition in dying patients. Continuous subcutaneous infusion (CSCI) of opioids is the cornerstone in treatment of pain in this last phase of life. Although morphine is the most frequent used opioid in this respect, burdensome adverse effects, like delirium and allodynia/hyperalgesia, can occur in dying patients, due to accumulation of morphine metabolites in decreasing renal function. Oxycodone seems preferable in this situation, as central effects of circulating metabolites of oxycodone are negligible. However, studies of sufficient quality investigating the clinical effect of this hypothesis are lacking at the moment. This study investigates whether there is a difference in occurrence of delirium and allodynia/hyperalgesia between oxycodone and morphine. Residents of hospices and somatic or psychogeriatric (PG) wards of nursing homes in the Netherlands, who are eligible for start of CSCI of an opioid for the treatment of pain in the terminal phase of life, are randomly assigned to one of two groups. One group receives CSCI of oxycodone and the other group CSCI of morphine. 117 patients per group are needed. Occurrence of delirium and allodynia/hyperalgesia is assessed three times a week until death of the participant. Quality of dying, as perceived by the patient's relatives, is assessed in an interview with a relative after death.

NCT ID: NCT03489577 Terminated - Sepsis Clinical Trials

The Role of Post-traumatic Inhibition of the Innate and Adaptive Immune System in the Development of Infectious Complications in Severely Injured Patients

Start date: June 2014
Study type: Observational

Patients admitted to the Intensive Care Unit after severe injury are prone to suffer from infectious complications and even sepsis. Despite tremendous efforts the etiology of this increased susceptibility to infectious pathogens is incompletely understood. Clinical signs and symptoms as well as current diagnostic clinical tests (WBC, CRP, cytokines, interleukines) lack sensitivity or specificity for adequate prediction of the development of infectious complications or sepsis. Neutrophil granulocytes, cells of the innate immune system, play an important role in the defence against invading bacterial pathogens and are crucial in preventing fulminant infections. For successful eradication of a bacterium neutrophils need to exert specific functions: chemotaxis, migration, phagocytosis, degranulation and production of radical oxygen species. Much research has focused on the effect of trauma on neutrophil's individual capacities to kill bacteria with conflicting interpretations as a result. For adequate determination of the neutrophil's capacity to eradicate bacteria from tissue of trauma patients we developed novel in-vitro assays in which neutrophils are tested for all of these functions combined. This assay allows us to identify dysfunctional neutrophils adequately. The main focus of this study is the determination of the functionality of aberrant neutrophils circulating in the peripheral blood of severly injured following trauma.
