Filter by:The main objective of the study is to evaluate the physiological-biochemical effects of physical training under artificially altered climatic conditions (using a hypoxic thermoclimatic chamber) in particular to determine the effect of such training on exercise capacity and physiological response, including the effect of training in high-performance athletes. The study will evaluate the effects of physical training and the simultaneous application of hypoxia and heat/cold on aerobic and anaerobic capacity and the physiological response of the human body. The aim of the study is to find the most favourable environmental conditions for physical training in order to maximise physical performance.
The aim of this randomized controlled study is to explore the hypoalgesic response of a 6 minutes of intermittent walking apneas training session at low lung volume in healthy subjects; also, as secondary objectives, to analyze the cardiovascular and respiratory response produced during the intervention.

The purpose of this clinical study is to validate the SpO2 accuracy of the Stryker Sustainability Solutions pulse oximetry sensors during motion conditions over the range of 70 -100% SaO2 as compared to arterial blood samples assessed by CO-Oximetry during conditions in which the subject is moving. The end goal is to provide supporting documentation for the SpO2 accuracy validation of the reprocessed sensors with motion indications.
Background: Sodium-glucose-cotransporter (SGLT) inhibition has been observed to reduce risk of cardiovascular events and kidney failure in persons with type 2 diabetes. People with type 1 diabetes also have increased risk of cardiovascular and kidney disease, and may benefit from SGLT-inhibition. The exact mechanism of how SGLT-inhibition benefits the kidneys are yet unknown. Change in renal hypoxia may be a factor. Objective: The primary aim of this study is to assess the effects of 12 weeks SGLT-1 and 2 inhibition on renal oxygenation in persons with type 1 diabetes and chronic kidney disease. Further aims are to study if renal oxygen consumption and response to SGLT-inhibition differs between people of African-Caribbean or Northern European decent. Additionally effects on left ventricular ejection fraction, kidney function and biomarkers in blood and urine will be explored. Method: 12 weeks treatment with oral sotagliflozin or matching placebo as intervention. Kidney oxygenation and perfusion parameters and left ventricular ejection fraction will be assessed by functional magnetic resonance imaging. Kidney function and biomarkers will be assessed according to local hospital laboratory guidelines. Design: Randomized, double-blinded, placebo-controlled, cross over intervention study. Study population: 69 persons with type 1 diabetes and diabetic kidney disease with albuminuria will be included, 39 at Steno Diabetes Center Copenhagen, 30 at King's College London. Endpoints: Primary end-point: Change from 0 to 12 weeks in dynamic R2*-weighted signal after treatment with sotagliflozin compared to placebo. Secondary endpoints: Change from 0 to 12 weeks with sotagliflozin compared with placebo on renal perfusion, renal artery flow, renal oxygen consumption, renal parenchymal triglyceride fraction, renal fibrosis, left ventricular ejection fraction, urinary albumin-creatinin ratio, ketone bodies, erythropoietin, pro brain natriuretic peptide, and plasma- and urine inflammation- and fibrosis biomarkers as well as difference after 12 weeks treatment in glomerular filtration rate. Timeframe: Inclusion of patients from february 2024. Last visit september 2025. Presentation spring 2026, publication fall 2026.

The aim of this project is to test the accuracy of pulse oximeters during mild, moderate and severe hypoxia. This is done by comparing the reading of the pulse oximeter during brief, steady state hypoxia with a gold-standard measurement of blood oxygen. This study will be done on healthy male or females between the age group of 18-50.
The study examines individuals admitted to the intensive care unit due to breathing difficulties resulting in not getting enough oxygen into their bodies. These patient will receive mechanical ventilation and this study aims to determine how the pressure inside the lungs changes when using two different modes of mechanical ventilation. The goal is to improve management and care of breathing difficulties by gaining insight into changes in lung pressure during mechanical ventilation, as well as comparing the effectiveness of the two ventilator modes.
