Inflammation and Metabolic Acidosis at Birth (AGAIN: AutophaGy AcIdosis Newborn)

Protection of brain development is a major aim in the Neonatal Intensive Care Unit. Neonatal encephalopathy (NE) occurs in 1.8 to 7.7 infants per 1000 births. Over the last six years, several randomized control trials have demonstrated that therapeutic hypothermia reduces the rate of death or disability at 18 months of age among infants who survived. However, the neurodevelopmental outcome in milder NE not treated with hypothermia remains unclear. A multicenter prospective observational study will be conducted to determine biological changes of mild neonatal encephalopathy who are not recruited for therapeutic hypothermia .

Health, Wellbeing and Performance in Law Enforcement Workers

This study aims to assess current health and fitness of law enforcement workers in various roles, and to evaluate the impact of an exercise intervention on markers on physical and mental wellbeing in this population. The intervention will consist of an exercise programme specifically targeted at improving, physical fitness and reducing musculoskeletal pain. Participants will be randomised to three groups: a face to face intervention group, an online intervention group an a control group. Self-reported physical health, musculoskeletal complaints, quality of sleep and occupational stress will be measured via questionnaires. Pre and post measures of fitness will be measured via functional strength testing and a cardiopulmonary exercise test. Pre and post cognitive function will be measured via computer-based cognitive tests and brain functional near-infrared spectroscopy (fNIRS). Systemic inflammation will be measured via hsCRP. Risk of typeII diabetes will be measured via HbA1c. Daily physical activity and quality of sleep will be measured via accelerometry and heart rate telemetry. It is hypothesised that, upon completion of the programme, there will be an improvement in cardiovascular fitness and physical strength, reduced musculoskeletal pain, improved cognitive readiness and improved overall mental health and wellbeing.

A Population-based Investigation of Asthma in the Telemark Region of Norway

Respiratory conditions impose an enormous burden on the individual and the society. According to the WHO World Health Report 2000, the top five respiratory diseases - including asthma and COPD - account for 17% of all deaths and 13% of all Disability-Adjusted Life Years (DALYs). Obstructive lung diseases are among the most common chronic diseases in working-aged populations affecting ~40 million individuals in Europe. The greatest economic burden of respiratory diseases on health services and lost production in the EU is due to COPD and asthma, at about €20 billion each for healthcare and €25 billion and €15 billion, respectively, for lost production. For Norway, there are no estimates of asthma prevalence for the country as a whole, but 80/1000 women and 55/1000 men used asthma medication in 2013 according to the national prescription register. Estimated annual deaths in Norway due to COPD were 4070 in 2015, which is 30% higher than for lung cancer. Unfortunately, a substantial proportion of patients are still difficult to treat. This underlines the need for better primary prevention and more knowledge regarding causes and exacerbating factors. Several risk factors for chronic respiratory diseases are identified, most important tobacco smoke, closely followed by air pollution and occupational exposure. However, according to recent reviews there is a lack of understanding regarding environmental risk factors and mechanisms of how these affect respiratory health, the importance of biological markers and comorbidity, and of socioeconomic risk factors. Moreover, there is a need for assessment of interactions between risk factors and between the individual and the environment. Telemark has a high proportion of craft- and industrial workers providing exposure contrasts. Furthermore, the use of medication against respiratory diseases and the rate of sick leave are higher in Telemark than elsewhere in Norway. Moreover, the county has a high rate of disability. There are previous studies from other parts of Norway, which have estimated the occurrence of respiratory diseases and provided valuable knowledge regarding some risk factors. However, these studies use crude measures of self-reported exposure and do not provide sufficient information on how to target intervention and implement effective prevention. In contrast to the Telemark study, these studies have not included register data or advanced modelling of environmental exposure.

Canadian Study of Arterial Inflammation in Patients With Diabetes and Vascular Events: EvaluatioN of Colchicine

Cardiovascular Disease (CVD) is a leading cause of death in the developed world. Atherosclerosis causes plaques in the blood vessels and is a common form of CVD. Inflammation is now recognized as a major cause of atherosclerosis. Therapies that target inflammation are being examined as a potential treatment option. Imaging to detect inflammation may be a solution to understand mechanisms and to optimize patient selection and outcomes for these drugs. Fluorodeoxyglucose (FDG) PET imaging can detect inflammation in the plaque and identify patients vulnerable to plaque rupture which cause events such as myocardial infarctions (MI) and strokes. The primary objective of this proposal(CADENCE) is to determine if the drug colchicine has an effect on plaque inflammation in patients at high risk for events (patients with diabetes or pre-diabetes and recent myocardial infarction, stroke or transient ischemic attacks (TIAs)). This mechanistic and proof-of-concept study will set the stage for future studies that will determine if inflammation imaging can be integrated into clinical practice to personalize decisions for anti-inflammation therapies.

Effects of Allopurinol on Inflammation and Ultrasonographic Changes in People With Elevated Uric Acid But no Symptoms

Hyperuricemia is a metabolic alteration defined as the presence of serum urate levels higher than 7 mg/dL. This has proven to be the maximum limit of solubility of urate in serum, any higher concentration leads to precipitation and eventually to the formation of monosodium urate (MSU) crystals. The accumulation of said crystals can manifest as gouty arthritis, uric acid nephropathy, urolithiasis or chronic tophaceous gout. A strong relation between hyperuricemia and other chronic degenerative diseases, including diabetes mellitus, systemic arterial hypertension, obesity and metabolic syndrome, has been consistently proven. Hypouricemic pharmacological agents have shown a decrease in cardiovascular complications and death in patients with gout. A series of studies conducted on individuals with asymptomatic hyperuricemia using musculoskeletal ultrasound (MSUS) have shown the presence of morphostructural changes suggestive of MSU crystal deposits, combined with an elevation in a series of inflammation markers to a degree similar to those found in patients with chronic gout. Even though, there is evidence of morphostructural damage in individuals with asymptomatic hyperuricemia, there are no clinical, laboratorial or imaging parameters that indicate when hypouricemic treatment should be started. This clinical trial is proposed as a proof of concept which is looking to evaluate if treatment with allopurinol induces changes in levels of inflammatory markers in individuals with asymptomatic hyperuricemia and morphostructural changes suggestive of MSU crystal deposits. this proof of concept is not looking to measure the efficiency, effectiveness or security of the treatment. Our Hypothesis is that Individuals with asymptomatic hyperuricemia and morphostructural changes evidenced by MSUS (double contour sing, tophi, aggregates) will show a decent in inflammatory markers and their morphostructural changes will diminish or revert after treatment with allopurinol.

PTP1B Implication in the Vascular Dysfunction Associated With Obstructive Sleep Apnea

Obstructive sleep apnea (OSA) syndrome is associated with increased vascular dysfunction and atherosclerosis. Especially, it has been shown that OSA associated intermittent hypoxia represents a pro inflammatory stimulus resulting in macrophage polarization. Protein tyrosine phosphatase 1B (PTP1B) is a negative regulator of insulin signaling pathways involved in atherosclerosis. It has been shown that myeloid PTP1B deficiency protects against atherosclerosis. As hypoxia has also been shown to increase PTP1B expression and activity, this study will evaluate the myeloid PTP1B expression and activity in patients with OSA as compared to controls and will investigate myeloid PTP1B involvement in the vascular pro inflammatory precess described in OSA.

Electrophysiological Phenotyping Of Patients at Risk of Ventricular Arrhythmia and Sudden Cardiac Death

Obesity, rheumatoid arthritis (RA) and gene-specific dilated cardiomyopathy (DCM) are common medical conditions. Small-scale studies have shown that these are associated with proarrhythmic changes on 12-lead electrocardiogram (ECG) and a higher risk of sudden cardiac death (SCD). However, these studies lack the deep electrophysiological phenotyping required to explain their observations. Electrocardiographic imaging (ECGi) is a non-invasive alternative to 12-lead ECG, by which epicardial potentials, electrograms and activation sequences can be recorded to study adverse electrophysiological modelling in greater depth and on a more focussed, subject-specific scale. Therefore, this study proposes to better define the risk of arrhythmia and understand the underlying adverse electrophysiological remodelling conferring this risk in three groups (obesity, RA and DCM). Firstly, data from two large, national repositories will be analysed to identify associations between routine clinical biomarkers and proarrhythmic 12-lead ECG parameters, to confirm adverse electrophysiological remodelling and a higher risk of arrhythmia. Secondly,ECGi will be performed before and after planned clinical intervention in obese and RA patients, and at baseline in titin-truncating variant (TTNtv)-positive and -negative DCM patients, to characterise the specific and potentially reversible conduction and repolarisation abnormalities that may underlie increased arrhythmic risk.
