Abstract

Genetic variants in the SLC6A1 gene can cause a broad phenotypic disease spectrum by altering the protein function. Thus, systematically curated clinically relevant genotype-phenotype associations are needed to understand the disease mechanism and improve therapeutic decision-making. We aggregated genetic and clinical data from 172 individuals with likely pathogenic/pathogenic (lp/p) SLC6A1 variants and functional data for 184 variants (14.1% lp/p). Clinical and functional data were available for a subset of 126 individuals. We explored the potential associations of variant positions on the GAT1 3D structure with variant pathogenicity, altered molecular function and phenotype severity using bioinformatic approaches. The GAT1 transmembrane domains 1, 6 and extracellular loop 4 (EL4) were enriched for patient over population variants. Across functionally tested missense variants (n = 156), the spatial proximity from the ligand was associated with loss-of-function in the GAT1 transporter activity. For variants with complete loss of in vitro GABA uptake, we found a 4.6-fold enrichment in patients having severe disease versus non-severe disease (P = 2.9 × 10-3, 95% confidence interval: 1.5-15.3). In summary, we delineated associations between the 3D structure and variant pathogenicity, variant function and phenotype in SLC6A1-related disorders. This knowledge supports biology-informed variant interpretation and research on GAT1 function. All our data can be interactively explored in the SLC6A1 portal (https://slc6a1-portal.broadinstitute.org/).

Abstract

Abstract We describe the geographical variation in tree species composition across Amazonian forests and show how environmental conditions are associated with species turnover. Our analyses are based on 2023 forest inventory plots (1 ha) that provide abundance data for a total of 5188 tree species. Within-plot species composition reflected both local environmental conditions (especially soil nutrients and hydrology) and geographical regions. A broader-scale view of species turnover was obtained by interpolating the relative tree species abundances over Amazonia into 47,441 0.1-degree grid cells. Two main dimensions of spatial change in tree species composition were identified. The first was a gradient between western Amazonia at the Andean forelands (with young geology and relatively nutrient-rich soils) and central–eastern Amazonia associated with the Guiana and Brazilian Shields (with more ancient geology and poor soils). The second gradient was between the wet forests of the northwest and the drier forests in southern Amazonia. Isolines linking cells of similar composition crossed major Amazonian rivers, suggesting that tree species distributions are not limited by rivers. Even though some areas of relatively sharp species turnover were identified, mostly the tree species composition changed gradually over large extents, which does not support delimiting clear discrete biogeographic regions within Amazonia.

Abstract

Abstract Background Cognitive impairment is prevalent across neuropsychiatric disorders but there is a lack of treatment strategies with robust, enduring effects. Emerging evidence indicates that altitude-like hypoxia cognition training may induce long-lasting neuroplasticity and improve cognition. We will investigate whether repeated cognition training under normobaric hypoxia can improve cognitive functions in healthy individuals and patients with affective disorders and the neurobiological underpinnings of such effects. Methods In sub-study 1, 120 healthy participants are randomized to one of four treatment arms in a double-blind manner, allowing for examination of separate and combined effects of three-week repeated moderate hypoxia and cognitive training, respectively. In sub-study 2, 60 remitted patients with major depressive disorder or bipolar disorder are randomized to hypoxia with cognition training or treatment as usual. Assessments of cognition, psychosocial functioning, and quality of life are performed at baseline, end-of-treatment, and at 1-month follow-up. Functional magnetic resonance imaging (fMRI) scans are conducted at baseline and 1-month follow-up, and [11C]UCB-J positron emission tomography (PET) scans are performed at end-of-treatment to quantify the synaptic vesicle glycoprotein 2A (SV2A). The primary outcome is a cognitive composite score of attention, verbal memory, and executive functions. Statistical power of ≥ 80% is reached to detect a clinically relevant between-group difference with minimum n = 26 per treatment arm. Behavioral data are analyzed with an intention-to-treat approach using mixed models. fMRI data is analyzed with the FMRIB Software Library, while PET data is quantified using the simplified reference tissue model (SRTM) with centrum semiovale as reference region. Discussion The results will provide novel insights into whether repeated hypoxia cognition training increases cognition and brain plasticity, which can aid future treatment development strategies.

6. Education, Collaboration and Pedagogical Phronesis: Essential Dimensions in Professional Learning and Development

Author

Bjørn Ribers, Gitte Miller Balslev, and Christine Revsbech Jensen

Abstract

This article aims to elaborate multiple dimensions of ethical perception in professionalism and introduces novel didactic viewpoints on educational routes through which professionals learn and develop the moral competencies essential to praxis. Results are discussed from recent innovative research projects on professional didactics, education and work practice. The article explores new research pathways through which to learn and develop professional ethics for teachers and social educators in collaboration between several agents in the field: students, teachers and educational leaders, as well as public institutions. Through lifelong learning trajectories, professionals are enabled to skilfully confront ethical challenges in reality, to develop concrete ethical perception and discernment based on practical wisdom, here defined as pedagogical phronesis. Based on a synthesis of empirical findings and theoretical perspectives, we argue that an interchanging dynamic between subjective experiences and dialogical learning constitutes several dimensions of tacit practical wisdom, which is accentuated in the perception of practice. These are: (1) the existential-phenomenological dimension, (2) the life-historical dimension, (3) the dimension of inter-relational competence, and (4) the social dimension of learning. Our findings have significance and applicability for policymaking, professional training, and educational development, as well as wider research projects on professional learning and development.

Abstract

Background: Increased gray matter volume (GMV) following electroconvulsive therapy (ECT) has been well-documented, with limited studies reporting a subsequent decrease in GMV afterwards. Objective: This study characterized the reversion pattern of GMV after ECT and its association with clinical depression outcome, using multi-site triple time-point data from the Global ECT-MRI Research Collaboration (GEMRIC). Methods: 86 subjects from the GEMRIC database were included, and GMV in 84 regions-of-interest (ROI) was obtained from automatic segmentation of T1 MRI images at three timepoints: pre-ECT (T0), within one-week post-ECT (T1), and one to six months post-ECT (T2). RM-ANOVAs were used to assess longitudinal changes and LMM analyses explored associations between GMV changes and demographical and clinical characteristics. Results: 63 of the 84 ROIs showed a significant increase-and-decrease pattern (RM-ANOVA, Bonferroni corrected p

Abstract

Introduction Noncommunicable diseases (NCDs) constitute a massive global burden and are the leading cause of death and disability worldwide. In Greenland, the prevalence of NCDs has historically been low. However, during the past approximately 70 years, life circumstances have changed dramatically resulting in increased life expectancy. Today, the proportion of inhabitants in Greenland ≥65 years has nearly tripled since the 1980s, and the prevalence of obesity and diabetes has increased rapidly within the past decades. The aim of this study was to describe the burden of selected NCDs in a primary care setting in Nuuk and compare it to a modern westernized suburban general practice in Denmark.Methods The study was performed as a cross sectional register-based study using data extracted from the electronic medical records (EMR) based on diagnosis codes from inhabitants living in Nuuk, Greenland, and a suburb in Denmark. Estimates of prevalence were age-standardized to the WHO world standard population.Results In both Nuuk and the Danish suburb, the highest prevalence was observed for hypertension (13.2% for both populations), followed by asthma (4.4 and 9.5%, respectively) and diabetes (4.3 and 2.9%, respectively). The age-standardized prevalences of diabetes, COPD, atrial fibrillation, and heart failure, were significantly higher in Nuuk, while seven NCDs including asthma, ischemic heart disease, arthritis urica, psoriasis, hyperthyreosis, hypothyreosis and osteoporosis were significantly higher in the Danish suburb.Conclusion In contrast to the disease pattern observed in Greenland in the last century, the prevalence of diagnosed NCDs in Nuuk is no longer rare. Thus, the overall prevalence of NCDs in the population of Nuuk is now comparable to or even higher than in the suburb in Denmark. This calls for increased focus on all NCDs in the primary healthcare system in Greenland and adaption of the primary healthcare services to a changed disease spectrum.

Abstract

As the globe gets more urbanised, the question about how natural biodiversity is structured in cities becomes increasingly pertinent. To contribute to an answer, we studied species richness and spatio-temporal structure of bees in a North European metropolitan area. A gradient of 13 sites in the city of Aarhus, Denmark, was censused from April to September 2016. Forty species, i.e. 29 solitary species (40 % of all individuals), ten Bombus species (28 %), and Apis mellifera (32 %), were sampled monthly in pan traps. (i) Information about species traits was extracted from the literature, and trait values were correlated and used to characterize the fauna. Most were soil-nesters, pollen generalists, and common. (ii) Habitat diversity within five concentric circles with trap at the centre and radii from 50 m to 1000 m was related to bee α diversity. The relationship was significant only within 1,000 m for all bees and for bumblebees. Solitary bee diversity was uncorrelated with habitat diversity at all spatial levels. (iii) Spatio-temporal structure was analysed as two networks, one for bees linked to sites, and one for bees linked to months. Link patterns were analysed for levels of nestedness, modularity, and spatio-temporal β diversity. The two networks were weakly and non-significantly nested, but strongly modular, being composed of five and four modules of co-occurring bees, respectively. (iv) Finally, we studied total β diversity, βTOTAL, being the sum of species turnover, βTURN, and species loss/gain or nestedness, βNEST. For both site and season, βTURN was higher than βNEST, and site βTOTAL was higher than season βTOTAL. One reason for this metacommunity structure may be a high spatio-temporal habitat patchiness, sustaining a rich biodiversity. Thus, a few large areas may not compensate for the loss of several small patches. Consequently, establishment of many green, even small habitats is recommended.

12. Improving Employability for Students through Co-Creation and External Collaboration: Experiences and Outcomes

Author

Andersson, Vibeke and Clausen, Helene Balslev

Abstract

This paper presents how a ninth semester teaching programme created employability skills among students. During the semester, students were expected to collaborate with a company or an organization to solve a task set by the external partner. The students used their academic and analytical skills and competences as a part of working with the 'product' (pitch and report), which they also delivered to the external partners. The students thus gradually became aware of the competences they used. The collaboration with companies and organizations formed part of and was integrated into the courses taught during the semester. The theories, concepts and themes presented in the instruction during the first part of the semester could be used by students in their collaboration with the external partner, both practically and theoretically. Students worked with external partners for six weeks during the second half of the semester.

Abstract

The severe impact of global warming, especially in the arctic region, have a multitude of consequences spanning from sea-level rises and freshening of the ocean, to significant changes to the animal life, biodiversity and species distribution. As the arctic regions are inherently remote and can be both hazardous and difficult to reach, research to improve our understanding of the climate change impact is often limited to short term field-campaigns. Here we present the Danish DISCO-2 student CubeSat mission, designed to meet the growing need for an Earth-observing platform. This mission leverages the rapid advancements in CubeSat technology over the past decades to overcome the limitations of traditional fieldwork campaigns. DISCO-2 will assist on-going arctic climate research with a payload of optical and thermal cameras in combination with novel in-orbit data analysis capabilities. It will further be capable of performing photogrammetric observations to determine ice volumes from deteriorating glaciers and provide surface temperatures, enabling studies of heat transfer between glaciers and arctic fjords. As a student satellite, the payload capabilities will also be offered to novel student research ideas throughout the mission life time. The modularity and wide range of of-the-shelf-components for CubeSats has facilitated an immense opportunity to tailor this earth observing CubeSat to accommodate specific scientific goals and further provided students at the participating universities with an unparalleled possibility to go from an initial research idea to a running CubeSat mission.

Abstract

Abstract Background About one third of patients with depression are in a condition that can be termed as “difficult-to-treat”. Some evidence suggests that difficult-to-treat depression is associated with a higher frequency of childhood trauma and comorbid personality disorders or accentuated features. However, the condition is understudied, and the effects of psychotherapy for difficult-to-treat depression are currently uncertain. The aim of this trial is to investigate the beneficial and harmful effects of 30 sessions of individual schema therapy versus treatment as usual for difficult-to-treat depression in the Danish secondary, public mental health sector. Methods In this randomized, multi-centre, parallel-group, superiority clinical trial, 129 outpatients with difficult-to-treat depression will be randomized (1:1) to 30 sessions of individual schema therapy or treatment as usual; in this context mainly group-based, short-term cognitive behaviour or psychodynamic therapy. The primary outcome is the change from baseline in depressive symptoms 12 months after randomization, measured on the observer-rated 6-item Hamilton Rating Scale for Depression. The secondary outcomes are health-related quality of life assessed with the European Quality of Life 5 Dimensions 5 Level Version, functional impairment assessed with the Work and Social Adjustment Scale, psychological wellbeing assessed with the WHO-5 Well-being Index, and negative effects of treatment assessed with the Negative Effects Questionnaire. Exploratory outcomes are improvement on patient self-defined outcomes, personal recovery, anxiety symptoms, anger reactions, metacognitive beliefs about anger, and perseverative negative thinking. Outcomes will be assessed at 6, 12, and 24 months after randomization; the 12-month time-point being the primary time-point of interest. Outcome assessors performing the depression-rating, data managers, statisticians, the data safety and monitoring committee, and conclusion makers for the outcome article will be blinded to treatment allocation and results. To assess cost-effectiveness of the intervention, a health economic analysis will be performed. Discussion This trial will provide evidence on the beneficial and harmful effects, as well as the cost-effectiveness of schema therapy versus treatment as usual for outpatients with difficult-to-treat depression. The results can potentially improve treatment for a large and understudied patient group. Trial registration ClinicalTrials.gov NCT05833087. Registered on 15th April 2023 (approved without prompts for revision on 27th April 2023).

Abstract

Summary: Here, we present a protocol for quantifying pyramidal neuron hyperexcitability in a mouse model of STXBP1 neurodevelopmental encephalopathy (Stxbp1hap). We describe steps for preparing brain slices, positioning electrodes, and performing an excitability test to investigate microcircuit failures. This protocol is based on recording layer 2/3 cortical pyramidal neurons in response to stimulation of two independent sets of excitatory axons that recruit feedforward inhibition microcircuits.For complete details on the use and execution of this protocol, please refer to Dos Santos et al.1 : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.

Abstract

Although physical activity and sedentary behavior are moderately heritable, little is known about the mechanisms that influence these traits. Combining data for up to 703,901 individuals from 51 studies in a multi-ancestry meta-analysis of genome-wide association studies yields 99 loci that associate with self-reported moderate-to-vigorous intensity physical activity during leisure time (MVPA), leisure screen time (LST) and/or sedentary behavior at work. Loci associated with LST are enriched for genes whose expression in skeletal muscle is altered by resistance training. A missense variant in ACTN3 makes the alpha-actinin-3 filaments more flexible, resulting in lower maximal force in isolated type IIA muscle fibers, and possibly protection from exercise-induced muscle damage. Finally, Mendelian randomization analyses show that beneficial effects of lower LST and higher MVPA on several risk factors and diseases are mediated or confounded by body mass index (BMI). Our results provide insights into physical activity mechanisms and its role in disease prevention.

Abstract

Abstract Background Morning reports are an essential component of physicians’ daily work. Attending morning reports is prioritized by junior doctors as it provides them with an opportunity to learn diagnostic reasoning through discussion of cases. While teaching formats during morning reports have previously been reported, an in-depth analysis of what learning opportunities exist, e.g., how teaching is enacted during morning reports, is lacking. This qualitative study explores learning opportunities during morning reports. Methods We used an explorative design based on video-recordings of 23 morning reports from two surgical departments, an internal medicine department and an emergency department. We used thematic analysis combined with and inspired by Eraut’s theoretical framework of workplace learning. Results Both formal and informal learning opportunities were identified. Formal learning opportunities had the character of planned teaching activities, and we identified four themes: (1) modes of teaching, (2) structure, (3) presenter role, and (4) participant involvement. Informal learning, on the other hand, was often implicit and reactive, while deliberate learning opportunities were rare. The data showed many missed opportunities for learning. Conclusion Both formal and informal learning opportunities are present during morning reports. However, a prevalent focus on medical topics exists, leaving other important aspects of the medical role under-discussed. Pedagogical methods could be employed more optimally, and harnessing the potential of missed opportunities should be encouraged.

Abstract

Abstract Using 2.046 botanically-inventoried tree plots across the largest tropical forest on Earth, we mapped tree species-diversity and tree species-richness at 0.1-degree resolution, and investigated drivers for diversity and richness. Using only location, stratified by forest type, as predictor, our spatial model, to the best of our knowledge, provides the most accurate map of tree diversity in Amazonia to date, explaining approximately 70% of the tree diversity and species-richness. Large soil-forest combinations determine a significant percentage of the variation in tree species-richness and tree alpha-diversity in Amazonian forest-plots. We suggest that the size and fragmentation of these systems drive their large-scale diversity patterns and hence local diversity. A model not using location but cumulative water deficit, tree density, and temperature seasonality explains 47% of the tree species-richness in the terra-firme forest in Amazonia. Over large areas across Amazonia, residuals of this relationship are small and poorly spatially structured, suggesting that much of the residual variation may be local. The Guyana Shield area has consistently negative residuals, showing that this area has lower tree species-richness than expected by our models. We provide extensive plot meta-data, including tree density, tree alpha-diversity and tree species-richness results and gridded maps at 0.1-degree resolution.

Abstract

Abstract Sexual dysfunction is prominent in Major Depressive Disorder (MDD) and affects women with depression more than men. Patients with MDD relative to healthy controls have lower brain levels of the serotonin 4 receptor (5-HT4R), which is expressed with high density in the striatum, i.e. a key hub of the reward system. Reduced sexual desire is putatively related to disturbed reward processing and may index anhedonia in MDD. Here, we aim to illuminate plausible underlying neurobiology of sexual dysfunction in unmedicated patients with MDD. We map associations between 5-HT4R binding, as imaged with [11C]SB207145 PET, in the striatum, and self-reported sexual function. We also evaluate if pre-treatment sexual desire score predicts 8-week treatment outcome in women. From the NeuroPharm study, we include 85 untreated MDD patients (71% women) who underwent eight weeks of antidepressant drug treatment. In the mixed sex group, we find no difference in 5-HT4R binding between patients with sexual dysfunction vs normal sexual function. However, in women we find lower 5-HT4R binding in the sexual dysfunctional group compared to women with normal sexual function (β = −0.36, 95%CI[−0.62:−0.09], p = 0.009) as well as a positive association between sexual desire and 5-HT4R binding (β = 0.07, 95%CI [0.02:0.13], p = 0.012). Sexual desire at baseline do not predict treatment outcome (ROC curve AUC = 52%[36%:67%]) in women. Taken together, we find evidence for a positive association between sexual desire and striatal 5-HT4R availability in women with depression. Interestingly, this raises the question if direct 5-HT4R agonism can target reduced sexual desire or anhedonia in MDD.

Abstract

SNAP25 is one of three neuronal SNAREs driving synaptic vesicle exocytosis. We studied three mutations in SNAP25 that cause epileptic encephalopathy: V48F, and D166Y in the synaptotagmin-1 (Syt1)-binding interface, and I67N, which destabilizes the SNARE complex. All three mutations reduced Syt1-dependent vesicle docking to SNARE-carrying liposomes and Ca2+-stimulated membrane fusion in vitro and when expressed in mouse hippocampal neurons. The V48F and D166Y mutants (with potency D166Y > V48F) led to reduced readily releasable pool (RRP) size, due to increased spontaneous (miniature Excitatory Postsynaptic Current, mEPSC) release and decreased priming rates. These mutations lowered the energy barrier for fusion and increased the release probability, which are gain-of-function features not found in Syt1 knockout (KO) neurons; normalized mEPSC release rates were higher (potency D166Y > V48F) than in the Syt1 KO. These mutations (potency D166Y > V48F) increased spontaneous association to partner SNAREs, resulting in unregulated membrane fusion. In contrast, the I67N mutant decreased mEPSC frequency and evoked EPSC amplitudes due to an increase in the height of the energy barrier for fusion, whereas the RRP size was unaffected. This could be partly compensated by positive charges lowering the energy barrier. Overall, pathogenic mutations in SNAP25 cause complex changes in the energy landscape for priming and fusion.

Abstract

ABSTRACTThe aim of this study was to estimate the prevalence of diagnosed diabetes in Greenland and evaluate quality of care according to sex, region and healthcare unit within regions. Data on all inhabitants registered with diabetes were extracted from the electronic medical record. We found a crude prevalence of diagnosed diabetes in the population aged ≥ 20 years to be 4.7%, and the prevalence of diabetes standardised to the WHO world population was 4.0%. Compared to males, a significantly higher proportion of females had mean glycated haemoglobin (HbA1c) level below 7% (68.9% vs. 57.5%) and blood pressure below 140/90 mmHg (83.4% vs. 73.5%). Regarding healthcare unit within regions, quality of care was higher in regional cities compared to smaller cities, concerning proportion of persons having blood pressure measured regularly (86.0% vs. 71.7%), urine tested for albuminuria (70.6% vs. 51.2%), receiving eye examination (86.9% vs. 79.5%) and foot examination (87.9% vs. 79.4%). In conclusion, the prevalence of diagnosed diabetes in Greenland is the highest reported yet. The overall quality of diabetes care was high and significantly improved compared to 2018. We observed geographical inequality in diabetes care and improvements in the quality of care in specific remote locations are necessary to minimise health care disparities.

Abstract

Arachnoid cysts are the most common incidental findings on brain scans and are considered benign congenital structures. However, recent research associates cysts with affective- and cognitive symptoms. Despite this, the prevailing approach is that only signs of mass effect or nerve compression are taken as indications for neurosurgical treatment. On a brain MRI of a 32-year-old woman with depression, collected as a part of the multi-modal deep-phenotyping research project, the BrainDrugs-Depression study, we found a 38 × 17 mm arachnoid cyst located on the frontoparietal convexity just above the right frontal lobe. As part of the project, the study participants also underwent high-density EEG as well as hot- and cold cognitive testing. The cyst did not cause structural or functional abnormalities in the brain as evaluated with MRI, EEG, and cognitive tests. It was concluded to be unrelated to her current depressive episode. Although we found no association between the cyst and the woman's depressive state, this case highlights the importance of excluding organic etiologies when seeing patients with depression.

Abstract

The sustainable management of wild useful palms is crucial for their long-term survival. To understand how populations respond to extraction, it is necessary to examine the impacts of extraction in relation to their life histories in their habitat. A suitable genus for studying extraction responses and understanding life histories is Geonoma, as it exhibits a variety of demographic strategies, has a high potential for use, and some species are considered as untapped sources. Two species, Geonoma orbignyana and G. undata, are used as ornamentals for domestic purposes and commercialized in small-scale markets. They differ in their habitats, with G. orbignyana found in the understory and G. undata in more open spaces, suggesting different life histories. Therefore, the main objective of this study was to simulate the impacts of extraction for ornamental purposes in G. orbignyana and G. undata and identify the relationship with their life histories. The research was conducted in the Andean Forest of Chicaque Natural Park, Colombia in 2019–2021. We determined the demography of the two species, using Integral Projection Models (IPMs), and simulated the extraction of juveniles, leaves, and fruits. We found that both species exhibited typical understory palm patterns in terms of survival and growth rates. However, G. orbignyana had lower maximum individual size and onset of fecundity, indicating understory strategies, while G. undata displayed mixed strategies. The population of G. undata declined during both census periods due to high elasticities on juveniles, and extracting of juveniles is unsustainable, contrary of extraction of fruits and leaves, that seems to be sustainable under certain scenarios. Similarly, the extraction of leaves and fruits in G. orbignyana is potentially sustainable if occurring on specific sizes and rates, but the extraction of juveniles depletes the population. These findings suggest that sustainable extraction practices can be implemented to untapped palm populations while ensuring their conservation. To achieve this, it is crucial to protect the sizes and processes related to the growth and survival of acaulescent juveniles. Only after ensuring their growth should any extraction activities be considered. By adopting these practices, we can promote the responsible use of palm resources and safeguard their long-term viability.

Abstract

ABSTRACTBackground: Chronic kidney disease (CKD) is a major health burden affecting more than 10% of the global population. It is a multifactorial disease with many risk factors attributed lifestyle diseases. The prevalence of CKD in Greenland is unknown; however, the prevalence of risk factors contributing to CKD is increasing.Objectives: To estimate the prevalence of CKD in Greenland.Methods: The study was a cross-sectional register-study including all Greenlandic residents aged ≥20 years with serum creatinine analysis within the last 2 years. We identified those with CKD based on eGFR and UACR and those registered with a CKD diagnosis code. Two limitations of the study are possible lack of data completeness and the reliance of a single time point to report CKD.Results: A total of 2,157 patients were identified with CKD with an age-standardised prevalence of 3.01%. Only 75 patients were registered with a diagnosis code for CKD. Approximately 80% of patients were classified with CKD stages 1–2.Conclusion: This is the first study reporting CKD in Greenland. We found a lower prevalence of CKD than reported by other studies, and a low number of patients correctly diagnosed with CKD. We call for increased awareness and diagnosis coding of CKD in Greenland.

Abstract

ABSTRACTThe aim of this study was to evaluate the activity within the primary health care (PHC) in Greenland by identifying the patterns of all registered contacts made by patients in 2021, and to compare the most frequently used types of contacts and diagnostic codes in Nuuk to the rest of Greenland. The study was designed as a cross-sectional register study using data from the national electronic medical records (EMR) and diagnostic codes from the ICPC-2-system. In 2021, 83.7% (46,522) of the Greenlandic population were in contact with the PHC, resulting in 335,494 registered contacts. The majority of the contacts with PHC was made by females (61.3%). On average, females were in contact with PHC 8.4 times per patient per year, while males were in contact with PHC 5.9 times per patient per year. The most frequently used diagnostic group was “General and unspecified”, followed by “Musculoskeletal” and “Skin”. The results are in line with studies from other northern countries and indicate an easily accessible PHC system, with a predominance of female contacts.

Abstract

ABSTRACTThe aim of this study was to estimate prevalence of patients with asthma in Greenland according to age, gender and residence and to investigate the associated quality of care. The study was performed as a cross-sectional study with data extracted from the Greenlandic electronical medical record. A total of 870 patients aged 12 years or above were diagnosed with asthma at the end of 2022, corresponding to a prevalence of 1.9%. In 2020, the total prevalence was 0.2%. The prevalence of patients aged 12 years or above with asthma was highest among patients in Nuuk (3.3%) compared with patients in the remaining parts of Greenland (1.1%). More women than men were diagnosed with asthma, and the prevalence increased with age from 20 to 59 years. The prevalence of current smokers was high among the asthma population. The quality of care was significantly higher among patients living in Nuuk for all process indicators compared with patients from the remaining parts of Greenland. The prevalence of asthma in Greenland is low compared to other comparable populations and might be underestimated. Initiatives supporting increased focus on diagnosing asthma are thus warranted.
