NCT ID: NCT06322862 Recruiting - Clinical trials for Bowel; Ischemic, Acute

Intraoperative Intestinal Perfusion Assessment by Fluorescence Angiography in Emergency Surgery

Start date: March 5, 2024
Phase: N/A
Study type: Interventional

This is a prospective, multicentre, non-randomized cohort study using real-time intraoperative visualization of bowel perfusion by indocyanine green (ICG) in all-cause bowel ischemia. At intraoperative finding of bowel ischemia, the initial intraoperative plan is noted and resection margins marked with a steril pen. A fluorescence angiography will be performed and the surgeon will note whether the suspected ischemic bowel is perfused, whether there is a change in the resection margins in centimeters, and if the intraoperative plan has changed. If resection is indicated and the strategy of choice is an anastomosis, a renewed fluorescence angiography will be performed to assess anastomotic perfusion.

NCT ID: NCT06322134 Active, not recruiting - Drowning Clinical Trials

Drowning Incidents Treated by the Danish SAR Helicopters

DROWN_SAR
Start date: March 1, 2024
Phase:
Study type: Observational

Improving oxygenation and ventilation in drowning patients early in the field is critical and may be lifesaving. This may be achieved by helicopter emergency medical services (HEMS) such as the Danish Air Ambulance, or the Royal Danish Air Force's Search And Rescue (SAR) helicopters. The SAR operates in all weather conditions and is equipped with a hoist system, able to hoist patients from the sea or small ships without helipads. This study aimed to estimate the incidence of drowning missions attended by the Royal Danish Air Force's SAR helicopter and describe patient characteristics and prehospital interventions.

Intensive Weight Loss Intervention Versus Usual Care for Adults With Severe and Complex Obesity

LightWAY
Start date: April 29, 2024
Phase: N/A
Study type: Interventional

In this trial, the aim is to assess the clinical benefits and harms, as well as cost-effectiveness of an intensive weight loss (IWL) intervention that includes total dietary replacements, behavioural support and weight-loss medication compared with existing weight management programmes within primary care for people with severe and complex obesity.

NCT ID: NCT06321432 Not yet recruiting - Obesity Clinical Trials

Intensive Weight Loss Intervention Versus Usual Care for Adults With Obesity

LightCARE
Start date: June 2024
Phase: N/A
Study type: Interventional

In this trial, the aim is to assess the clinical benefits and harms, as well as cost-effectiveness of an intensive weight loss (IWL) intervention that includes total dietary replacements, behavioural support and weight-loss medication compared with existing weight management programmes within primary care for people with obesity class I or uncomplicated obesity class II or higher.

NCT ID: NCT06320197 Recruiting - Drowning Clinical Trials

In Situ Simulation Training in Lifeguard Organisations

DROWN_INSITU
Start date: January 1, 2018
Phase:
Study type: Observational

This retrospective study will analyse a dataset consisting of 919 in situ simulation assessments collected between 2018 and 2023 in a Danish nationwide surf lifeguard organisation. The primary objective is to estimate the pass/fail ratio of in situ simulation assessments. The secondary objective is to analyse risk factors associated with a failed assessment. These results may guide future efforts to improve the Danish surf lifeguard training program.

NCT ID: NCT06319781 Recruiting - Psoriasis Clinical Trials

A Pilot Cohort Study of Risk Factors and Novel Methods of Skin Lesion Assessments in Adults With Atopic Dermatitis, Alopecia Areata, Psoriasis or Vitiligo

Derma-001
Start date: December 15, 2023
Phase:
Study type: Observational

The objective of the study is to explore various clinical and biochemical parameters and their potential associations with disease severity, activity, and prognosis in atopic dermatitis, psoriasis, alopecia areata, and vitiligo. Further, the study aims at validating remote assessments of skin lesions, using smartphone-acquired photos. The study will also assess the feasibility and compliance with weekly remote-assessments and patient-reported data collection over the full study period of one year. The study will observe patients through a period of one year and will provide detailed information concerning the type and dose of medication used, as well as data to evaluate the disease activity with high resolution during this period. The study will involve collection of serum samples for exploratory biomarkers, and punch biopsies. A total of approximately 370 patients, divided into the four disease areas of atopic dermatitis, alopecia areata, psoriasis, and vitiligo, will be enrolled in the study. Using a combination of self-reported and on-site assessments and procedures, the intent is to observe the natural history of patients with select dermatological conditions, investigate tissue characteristics associated with disease activity and symptoms, and evaluate the validity of remote assessment of lesions, and feasibility of weekly self-acquired smart-phone images of skin lesions for remote assessment.

NCT ID: NCT06319274 Recruiting - Clinical trials for Endothelial Dysfunction

Infusion of Prostacyclin vs Placebo for 72-hours in Mechanically Ventilated Patients With Acute Respiratory Failure

COMBAT-ARF
Start date: April 15, 2024
Phase: Phase 2
Study type: Interventional

The purpose of this clinical trial is to investigate the efficacy and safety of continuous intravenous administration of low dose iloprost versus placebo for 72-hours, in 450 mechanically ventilated patients with infectious respiratory failure. The study hypothesis is that iloprost may be beneficial as an endothelial rescue treatment as it is anticipated to deactivate the endothelium and restore vascular integrity in patients suffering from respiratory failure caused by endothelial breakdown, ultimately improving survival.

NCT ID: NCT06318299 Not yet recruiting - Ketosis Clinical Trials

Effects of Exogenous Ketone Ester Supplementation on 3-hydroxybutyrate Concentrations in Human Cerebrospinal Fluid

KetoBrain
Start date: March 2024
Phase: N/A
Study type: Interventional

It is well established that the brain is capable of consuming ketone bodies, especially during low glucose availability, e.g. fasting. Cerebral metabolism of ketone bodies depends on passage of the blood brain barrier and especially the global blood concentration of ketone bodies. Ketone bodies can be administered exogenously, and the most commonly used in clinical trials is 3-hydroxybutyrate (3-OHB). 3-OHB is carried by simple diffusion and facilitated diffusion through several monocarboxylic acid transporters (MCTs) across the blood-brain barrier. To our knowledge, no studies in human adults exist that concurrently measure 3-OHB concentrations in blood and cerebrospinal fluid (CSF) after ingestion or infusion of exogenous ketone supplementation, necessitating further study. Aims: - The 3-OHB CSF/blood ratio after oral ingestion of 30 g ketone ester - primary endpoint - The window of effect: Ketone supplementation 1 h or 2 h before CSF sampling - If concentration measurements by point-of-care testing are non-inferior to mass spectrometry - If acute 3-OHB ingestion increases plasma brain-derived neurotrophic factor (BDNF) levels

NCT ID: NCT06318260 Recruiting - Clinical trials for ATTR Amyloidosis Wild Type

Haemodynamic Effects of Dobutamine in Patients With Wild-type Transthyretin Amyloid Cardiomyopathy (ATTRwt)

DobATTR
Start date: April 8, 2024
Phase: Phase 1/Phase 2
Study type: Interventional

The goal of this clinical trial is to test the effects of the inotropic drug named dobutamine, in patients with wild-type Transthyretin Amyoid Cardiomyopathy (ATTRwt). The main questions it aims to answer are: - What are the effects of increasing dosages of dobutamine infusion on cardiac output and filling pressures in patients with symptomatic ATTRwt. - Safety of dobutamine infusion in this patient population. Participants will be given increasing dosages of dobutamine infusion, and its effect on cardiac output and filling pressures will be assessed non-invasively by echocardiography, and invasively by right heart catheterization, simultaneously.

NCT ID: NCT06315790 Recruiting - Clinical trials for Trigeminal Neuralgia

Four visits are planned: 1) Introduction and baseline data collection, 2) Medical evaluation and treatment assignment, 3) Follow-up with biomarker analysis, and 4) Trial conclusion interview. 80 participants will be included and randomized 1:1.
