Asthma in Greenland - development and evaluation of the asthma symptom score.

This study describes the development of the Asthma Symptom Score (ASS) and evaluates its accuracy and internal consistency in Greenlandic and Danish, using clinical interviews based on Global Initiative for Asthma guidelines as the gold standard. A cross-sectional study was conducted across all regions of Greenland, targeting citizens aged 12+, using data from the electronic medical record. The ASS ( = 94) was validated against clinical interviews using a receiver operating characteristic curve, yielding an area under the curve estimate of 0.

Surveillance of invasive beta-haemolytic streptococci in Denmark, 2012 to 2023: A nationwide study.

Objectives: To analyse trends in incidence, seasonality, and antimicrobial resistance of invasive beta-haemolytic streptococci (iBHS) in Denmark from 2012 to 2023.

Methods: Nationwide laboratory surveillance included submission of invasive isolates of Lancefield group A, B, C, and G streptococci from blood, cerebrospinal fluid, and other sterile sites to the National Reference Laboratory. Incidence rates (IRs) per 100,000 were calculated.

Measurement of renal cortex perfusion: A direct comparison of arterial spin labelling magnetic resonance imaging and [O]HO positron emission tomography.

Purpose: Reliable information about renal blood supply is important to understand kidney physiology and diseases. Arterial spin labeling MR (ASL-MR) imaging and [O]HO positron emission tomography (PET) can noninvasively measure tissue perfusion but have never been directly compared. Using a hybrid PET/MR scanner, we performed simultaneous cortex perfusion measurements to assess repeatability and reproducibility of both modalities and establish their mutual correlation.

Societal and biological approaches to diabetes prevention and care for Inuit populations: a narrative review.

The Inuit populations that inhabit the Arctic regions have adapted to survive in extreme conditions. However, recent societal changes and colonisation have led to rapid shifts in diet and physical activity, increasing the burden of chronic diseases, especially diabetes, in these regions. In addition, modern-day Inuit face significant challenges in accessing diabetes care and prevention and awareness programmes because of geographical isolation and fragmented healthcare services.

Mesenchymal stem cell therapy does not enhance fat graft retention: Cryopreserved and cultured syngeneic and allogeneic MSCs in a rat model.

Background: Fat grafting is a gentle technique used to correct soft tissue defects but is challenged by low graft survival rates. To enhance retention, mesenchymal stromal cells (MSCs), have been explored. Autologous MSC-therapy have shown promise but come with logistical and cost challenges.

Metabolic changes during cardiac regeneration in the axolotl.

Background: The axolotl is a prominent model organism of heart regeneration due to its ability to anatomically and functionally repair the heart after an injury that mimics human myocardial infarction. In humans, such an injury leads to permanent scarring. Cardiac regeneration has been linked to metabolism and the oxygenation state, but so far, these factors remain to be detailed in the axolotl model.

A Narrative Review on Manufacturing Methods Employed in the Production of Mesenchymal Stromal Cells for Knee Osteoarthritis Therapy.

Knee osteoarthritis (OA) is a chronic, progressive, inflammatory, and degenerative whole-joint disease. Early-stage OA treatments typically include physiotherapy, weight-loss, pain relief medications, and intra-articular knee injections, such as corticosteroids, hyaluronic acid, or platelet-rich plasma. These treatments primarily provide symptomatic relief rather than reversing or halting disease progression.

High Prevalence and Common Forms of Maturity-onset Diabetes of the Young in Greenland.

Objectives: Population studies have identified common genetic variants contributing substantially to the burden of diabetes in Greenland. However, the handling of suspected monogenic diabetes in diabetes clinics in Greenland has not been described. In this study we aimed to describe the referral rate, prevalence, and genetic causes of clinically identified monogenic diabetes in Greenland.

No associations between neuroborreliosis in children and psychiatric neurodevelopmental disorders: a nationwide, population-based, matched cohort study.

Background: It has been suggested that neuroborreliosis in children can manifest as psychiatric neurodevelopmental disorders or cause long-term neurodevelopmental sequelae. However, previous studies were limited by size and design.

Methods: We performed a nationwide, population-based, matched cohort study in Denmark between 1995 and 2021.

This review investigates that effective cancer treatment enhances the number of survivors in Denmark, but late complications like chemotherapy-induced peripheral neuropathy (CIPN) are a challenge. CIPN affects sensory nerves and can persist post-treatment. Diagnosis relies on symptoms and the medical history.

Prevalence of cardiovascular and other selected diseases among Greenlanders with and without type 2 diabetes.

This study aims to estimate the prevalence of cardiovascular disease, kidney disease, and other selected diseases including hypertension, atrial fibrillation, asthma, chronic obstructive lung disease, osteoarthritis, osteoporosis, psoriasis and depression among Greenlanders living in Nuuk with and without type 2 diabetes (T2D). The study was designed as a cross-sectional case-control study based on data from the electronic medical record (EMR) in Greenland. Persons with a registered T2D diagnosis in EMR and residence in Nuuk ( = 435) were included.

Skeletal muscle from TBC1D4 p.Arg684Ter variant carriers is severely insulin resistant but exhibits normal metabolic responses during exercise.

In the Greenlandic Inuit population, 4% are homozygous carriers of a genetic nonsense TBC1D4 p.Arg684Ter variant leading to loss of the muscle-specific isoform of TBC1D4 and an approximately tenfold increased risk of type 2 diabetes. Here we show the metabolic consequences of this variant in four female and four male homozygous carriers and matched controls.

Ex Vivo Simultaneous HO Positron Emission Tomography and Magnetic Resonance Imaging of Porcine Kidneys-A Feasibility Study.

Unlabelled: The aim was to establish combined HO PET/MRI during ex vivo normothermic machine perfusion (NMP) of isolated porcine kidneys. We examined whether changes in renal arterial blood flow (RABF) are accompanied by changes of a similar magnitude in renal blood perfusion (RBP) as well as the relation between RBP and renal parenchymal oxygenation (RPO).

Methods: Pig kidneys (n = 7) were connected to a NMP circuit.

Feasibility of a 12 weeks supervised exercise training intervention among people with Maturity Onset Diabetes of the Young (MODY) or type 2 diabetes in Greenland.

Preventing and managing Type 2 diabetes (T2D) involves adopting healthy lifestyle habits such as balanced nutrition and regular exercise. Maturity Onset Diabetes of The Young (MODY) shares diagnostic characteristics with T2D, but exercise responses in MODY remain unclear. In Greenland, MODY is 4-5 times more common than in other countries.

Risk of psychiatric neurodevelopmental disorders after meningitis in childhood: a nationwide, population-based cohort study.

Background: Few studies have investigated the risk of psychiatric neurodevelopmental disorders (PNDD) after childhood meningitis.

Methods: Nationwide population-based cohort study (Denmark, 1995-2021) of children with positive cerebrospinal fluid for bacteria or enterovirus, stratified on age as young infants (0 to <90 days,  = 637) or older children (≥90 days to <17 years,  = 1,218). We constructed a comparison cohort from the general population ( = 18,550), and cohorts of siblings of participants.

Inuit population have shorter gastric emptying, higher duodenal motility and altered pan-enteric micromilieu: a comparative study between Greenlandic and Danish populations with and without type 2 diabetes.

Gastrointestinal function plays a pivotal role in nutrient absorption and overall digestive health. Abnormal gastric emptying is closely linked to type 2 diabetes, impacting blood glucose regulation and causing gastrointestinal symptoms. This study aims to investigate and compare segmental transit times, motility indices, and micromilieu between Greenlandic Inuit and Danish individuals with and without type 2 diabetes.

High Prevalence of Atrial Fibrillation Found in the Capital of Greenland When Using Continuous Electrocardiogram Monitoring: A Cross-Sectional Study.

Background: Atrial fibrillation (AF) increases the risk of conditions such as ischemic stroke, dementia, and heart failure, and early detection is crucial. In Greenland, ischemic strokes are common, and the prevalences of AF risk factors are increasing. Studies based on 30-second electrocardiograms (ECGs) and diagnosis codes so far have indicated either a low prevalence of AF or a prevalence comparable to that in other Western countries, such as Denmark.

Healthcare-seeking behaviour preceding diagnosis of Lyme neuroborreliosis: population-based nationwide matched nested case-control study.

Objectives: To identify diagnostic opportunities, we investigated healthcare-seeking behaviour among patients with Lyme neuroborreliosis (LNB) within 28 weeks before diagnosis.

Methods: We conducted a population-based, nationwide matched nested case-control study (Denmark, 2009-2021). As cases, we included all Danish residents with LNB (positive Borrelia burgdorferi intrathecal antibody index test and cerebrospinal fluid pleocytosis).

Obtainment of prescribed analgesics among patients with Lyme neuroborreliosis; a nationwide, population-based matched cohort study.

Background: Radicular pain is the most predominant symptom among adults with Lyme neuroborreliosis (LNB) but the duration preceding and following diagnosis remains unknown. We aimed to investigate whether patients with LNB have increased obtainment of analgesics before and after diagnosis and for how long.

Methods: We performed a nationwide, population-based, matched cohort study (2009-2021).
