RESUMO
Health inequities for ethnically minoritised patients are well-documented. In this ethnographic study, we follow thirteen patients categorised as 'ethnic minorities' in Danish health care during hospitalisation in three orthopaedic wards across two hospitals. The categorisation of 'ethnic minority patient' has been problematised for its Eurocentric origin and practices within Westernised health care. We use ethnicised to emphasise the process of becoming minoritised based on markers of physical appearance, religious symbols, language or names. Access to health care also rely on perceived legitimacy as health-care recipients which requires work by patients. We demonstrate the workings patients categorised as 'ethnic minorities' engage in by (re)producing othering ideas about non-Danishness, including distancing from other patients perceived as problematic. These were then (counter)produced by positioning oneself as the opposite, as deserving health-care receivers by displaying welfare reciprocity, supporting egalitarian ideas by discounting discriminatory experiences, showing gratitude and identifying staff with good vibes. We propose these doings as creating overwork. This theoretical approach enables a sensitivity towards subtle and covert workings for patients placed in the margins of health care. In this study, overwork is closely related to notions of Danishness and takes on specific forms within a modernised and universalised Danish health-care system.
RESUMO
In this article, we discuss the practice of conducting research in one's own field, in this case, from a position as a researcher with a nursing background doing fieldwork in a hospital and in one's own organization, an orthopedic surgical department. We show how an "insider" researcher position paves the way for analytical insights about sleep as an institutional phenomenon in the orthopedic surgical infrastructure and how acute and elective patient trajectories differ but build on the same logic, creating the same dynamics of inclusion and exclusion. Through a situated and sociomaterial perspective, we analyze different clinical interactions in which we follow the hospital bed as an example of a central relational element that co-creates sleep as an institutional phenomenon. Inspired by Karen Barad, we demonstrate how to move diffractively when doing and analyzing fieldwork and argue how moving diffractively as a researcher doing fieldwork "at home" is productive and challenges the concept and demand of "distance" as the phenomenological exercise in fieldwork.

PD-1/PD-ligand-axis immunotherapy-mediated activation of T-cells for cancer cell elimination is a promising treatment of nonsmall cell lung cancer (NSCLC). However, the effect of immunotherapy on intracellular signaling pathways in cancer cells still needs further delineation. Repulsive Guidance Molecule b (RGMb), a regulator of Bone Morphogenetic Proteins (BMPs) signaling, interacts with the PD-ligand, PD-L2, at cancer cell membranes. Accordingly, a clarification of the functions of RGMb and its relation to PD-L2 might provide insight into NSCLC cell signaling responses to PD-1/PD-ligand-axis immunotherapy. In this study, the functions of RGMb and PD-L2 were examined using the two NSCLC cell lines HCC827 and A549. CRISPR/Cas9 was used to decrease the expression of RGMb and PD-L2, while lentiviral vectors were used to increase their expression. Downstream effects were examined by RT-qPCR and immunoassays. Ectopic expression of RGMb impacted BMP2-induced expression of ID1 and ID2 messenger RNA (mRNA) independently of PD-L2, while RGMb depletion by CRISPR/Cas9 did not affect the BMP2-mediated induction of ID1, ID2, and ID3 mRNA. However, depletion of RGMb resulted in a partial epithelial-mesenchymal transition (EMT) gene expression profile in HCC827 cells, which was not mimicked by PD-L2 depletion. The results show that RGMb is a coregulator of BMP signaling and hence, ID mRNA expression and that RGMb can control the EMT balance in NSCLC cells. However, RGMb appears to exert these functions independently of PD-L2, and accordingly, the PD-1/PD-ligand axis for immune surveillance in NSCLC cells.
RESUMO
General practitioners (GPs) in the Region of Southern Denmark were randomly allocated to a range of interventions to optimize their use of Vitamin D tests over one year. The aim of the current survey study was to investigate GPs assessment of the interventions. Using REDCap web-platform, we invited 638 GPs to participate in a survey about their experiences of guidelines, feedback reports, non-interruptive alerts, and interruptive alerts. The questions were customized for the different interventions. We received responses from only 131 GPs (21%), but no differences in gender, age, or type of GP clinic were observed between responders and invited GPs. Approximately half of the GPs found that guidelines were helpful, and a similar proportion of GPs read the feedback reports 'often' or 'always'. The pop-up alerts were accepted when used for maximum three months for often-used tests. In contrast, alerts were accepted for long periods for rarely-used tests. The groups that were exposed to the interruptive alert found it 'problematic' that it appeared every time vitamin D was requested. Guidelines and feedback reports on tests numbers were accepted, but it was previously found, that they had little effect on improving the use of biochemical tests. Pop-up alerts in the requesting IT system can produce alert fatigue. Future research should focus on developing feedback reports that - when possible - also include relevant clinical information, and pop-up alerts should for often used tests be displayed only for weeks or a few months, but can be repeated.

Venous thromboembolism is a common complication of cancer. The prevalence varies according to cancer type and increases proportionally with the stage of cancer. In the past 15-20 years, low molecular weight heparin has been recommended as the first-line treatment. New international guidelines now allow for use of direct factor Xa inhibitors both as prophylaxis and treatment for venous thromboembolism. Prophylaxis should as a general rule only be initiated in patients with moderate to high risk. Bleeding risk assessment is important before starting anticoagulation. Both thrombosis and bleeding risk can change and should therefore be assessed on an ongoing basis. In this clinical review, use of anticoagulation therapy in cancer patients is discussed with particular emphasis on the use of direct factor Xa inhibitors.

BACKGROUND & AIMS: Individual risk for developing alcohol-related liver disease (ALD) varies greatly. We hypothesized that metabolic risk factors and genetic polymorphisms predict severity of ALD. METHODS: Biopsy-controlled, cross-sectional study in patients with a history of excessive drinking. We measured the homeostatic model assessment of insulin resistance (HOMA-IR), plasma triglycerides, high- and low-density lipoproteins (HDL, LDL), and total cholesterol. Moreover, we genotyped four single nucleotide polymorphisms in PNPLA3 (rs738409C>G), TM6SF2 (rs58542926C>T), MBOAT7 (rs641738C>T), and HSD17B13 (rs72613567T>TA). We assessed predictors of higher fibrosis stage using multivariable ordered logistic regression. RESULTS: Of 325 included patients, 25% had severe fibrosis or cirrhosis and 59% had HOMA-IR ≥2.5. HOMA-IR increased for each fibrosis stage, while there was a similar decrease in LDL and total cholesterol. Individuals with risk variant PNPLA3 rs738409-G or TM6SF2 rs58542926-T had higher fibrosis stage. In multivariable regression, HOMA-IR ≥2.5 (OR = 3.04, 95% CI 1.90-4.87), LDL <2.60 mmol/L (OR = 2.05, 95% CI 1.33-3.16), TM6SF2 rs58542926-T (OR = 1.99, 95% CI 1.17-3.37), age above 50 years (OR = 1.66, 95% CI 1.03-2.70), and PNPLA3 rs738409-G (OR = 1.54, 95% CI 1.11-2.12) independently predicted higher fibrosis stage. Independent predictors of hepatic inflammatory activity were HOMA-IR, active drinking, age, and PNPLA3 risk variant. Active drinking, elevated triglycerides, and PNPLA3 risk variant predicted steatosis. CONCLUSIONS: Insulin resistance is the strongest predictor of liver fibrosis stage and hepatic inflammation in patients with alcohol-related liver disease. Genetic susceptibility further aggravates this risk. These data highlight the clinical value of detailed metabolic and genetic profiling of patients with excessive alcohol use.

OBJECTIVES: The use of laboratory tests increases worldwide, and to some extent their use is likely to be inappropriate. Although primary care is responsible for a substantial proportion of requests, this sector is less extensively investigated than hospitals. METHODS: We tested the effect of six combinations of four interventions applied to 313 primary care clinics, using vitamin D as model test (253,762 vitamin D results). We evaluated the changes in test numbers in the six intervention groups compared to the control group, and whether interventions resulted in more homogenous test use within groups or affected the distribution of test results. All interventions included information on vitamin D testing guidelines. Four groups were exposed to a non-interruptive alert in the ordering IT-system and in two groups this was supplemented by an interruptive alert. Half of the groups received monthly feedback reports. RESULTS: Application of alerts, irrespective of the combination with feedback reports, resulted in significantly reduced test numbers (maximum -46%). Guidelines either alone or combined with feedback reports did not cause significant difference from the control group. The within-group requesting pattern changed significantly for only two of the groups. The distribution of low and normal vitamin D results within groups showed no signs of more appropriate use of the test in any of the groups. CONCLUSIONS: Some of the interventions reduced the number of tests, but there were no indications of improved adherence to the guidelines. The interventions may have led to under-utilization of the test and thus should be used with care.

The Scandinavian welfare states are known for their universal access to healthcare; however, health inequalities affecting ethnic minority patients are prevalent. Ethnic minority patients' encounters with healthcare systems are often portrayed as part of a system that represents objectivity and neutrality. However, the Danish healthcare sector is a political apparatus that is affected by policies and conceptualisations. Health policies towards ethnic minorities are analysed using Bacchi's policy analysis, to show how implicit problem representations are translated from political and societal discourses into the Danish healthcare system. Our analysis shows that health policies are based on different ideas of who ethnic minority patients are and what kinds of challenges they entail. Two main issues are raised: First, ethnic minorities are positioned as bearers of 'culture' and 'ethnicity'. These concepts of 'othering' become both explanations for and the cause of inappropriate healthcare behaviour. Second, the Scandinavian welfare states are known for their solidarity, collectivism, equality and tolerance, also grounded in a postracial, colour-blind and noncolonial past ideology that forms the societal self-image. Combined with the ethical and legal responsibility of healthcare professionals to treat all patients equally, our findings indicate little leeway for addressing the discrimination experienced by ethnic minority patients.

Laboratory tests are important tools in primary care, but their use is sometimes inappropriate. The aim of this review is to give an overview of interventions applied in primary care to optimize the use of laboratory tests. A search for studies was made in the MEDLINE and EMBASE databases. We also extracted studies from two previous reviews published in 2015. Studies were included if they described application of an intervention aiming to optimize the use of laboratory tests. We also evaluated the overall risk of bias of the studies. We included 24 studies. The interventions were categorized as: education, feedback reports and computerized physician order entry (CPOE) strategies. Most of the studies were classified as medium or high risk of bias while only three studies were evaluated as low risk of bias. The majority of the studies aimed at reducing the number of tests, while four studies investigated interventions aiming to increase the use of specific tests. Despite the studies being heterogeneous, we made results comparable by transforming the results into weighted relative changes in number of tests when necessary. Education changed the number of tests consistently, and these results were supported by the low risk of bias of the papers. Feedback reports have mainly been applied in combination with education, while when used alone the effect was minimal. The use of CPOE strategies seem to produce a marked change in the number of test requests, however the studies were of medium or high risk of bias.

European Union (EU) Directive 2013/55/EC (The Recognition of Professional Qualifications) allows Member States to decide on a common set of minimum knowledge, skills and competences that are needed to pursue a given profession through a Common Training Framework. To be adopted the framework must combine the knowledge, skills and competences of at least one third of the Member States. Professionals who have gained their qualifications under a Common Training Framework will be able to have these recognised automatically within the Union. The backbone of the European Federation of Clinical Chemistry and Laboratory Medicine's (EFLM) proposed Common Training Framework for non-medical Specialists in Laboratory Medicine is outlined here. It is based on an Equivalence of Standards in education, training, qualifications, knowledge, skills, competences and the professional conduct associated with specialist practice. In proposing the recognition of specialist practice EFLM has identified 15 EU Member States able to meet Equivalence and in whom the profession and/or its training is regulated (an additional EU Commission requirement). The framework supports and contributes to the Directive's enabling goals for increasing professional mobility, safeguarding consumers and ensuring a more equitable distribution of skills and expertise across the Member States. It represents EFLM's position statement and provides a template for professional societies and/or competent authorities to engage with the EU Commission.

AIM: To explore how the media and socially established hero narrative, affected the nursing staff who worked in the frontline during the first round of the COVID19-pandemic. BACKGROUND: During the COVID19-pandemic, both media, politicians and the public have supported and cheered on the frontline healthcare workers around the world. We have found the hero narrative to be potentially problematic for both nurses and other healthcare workers. This paper presents an analysis and discussion of the consequences of being proclaimed a hero. DESIGN: Hospital ethnography including fieldwork and focus groups. METHOD: Empirical data was collected in a newly opened COVID19-ward in a university hospital in the urban site of Copenhagen, Denmark. Fieldwork was performed from April until the ward closed in the end of May 2020. Succeeding focus group interviews with nursing staff who worked in the COVID19-ward were conducted in June 2020. The data were abductively analysed. RESULTS: The nursing staff rejected the hero narrative in ways that show how the hero narrative leads to predefined characteristics, ideas of being invincible and self-sacrificing, knowingly and willingly working in risk, transcending duties and imbodying a boundless identity. Being proclaimed as a hero inhibits important discussions of rights and boundaries. CONCLUSION: The hero narrative strips the responsibility of the politicians and imposes it onto the hospitals and the individual heroic health care worker. IMPACT: It is our agenda to show how the hero narrative detaches the connection between the politicians, society and healthcare system despite being a political apparatus. When reassessing contingency plans, it is important to incorporate the experiences from the health care workers and include their rights and boundaries. Finally, we urge the media to cover a long-lasting pandemic without having the hero narrative as the reigning filter.

RATIONALE: Patients with radiation-induced enteropathy (RE) after cancer treatment show similar symptoms as patients with irritable bowel syndrome (IBS). The low fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAP) diet (LFD) is a widespread management strategy for IBS. We aimed to investigate if there may be a positive effect of LFD on symptoms and health-related quality of life (HRQOL) in patients with RE. METHODS: In an open non-controlled pilot study, 11 patients (all female) with RE-related IBS symptoms were recruited largely based on own initiative. All followed LFD for four weeks. IBS Severity Scoring System (IBS-SSS) and IBS Symptom Questionnaire (IBS-SQ) were used to assess symptoms. Short Form Nepean Dyspepsia Index (SF-NDI) and 12-item Short Form Health Survey (SF-12) evaluated HRQOL. A three day food record was used to estimate baseline intake of FODMAPs and to reveal dietary changes. RESULTS: FODMAP intake was successfully reduced, although LFD was found a burdensome intervention. IBS symptoms improved significantly based on mean total score of IBS-SSS and IBS-SQ, which changed from 310.2 ± 60.7 to 171.4 ± 107.2 (p = .001) and 27.4 ± 4.1 to 15.7 ± 10.1 (p = .002). HRQOL improved based on SF-NDI total score (30.5 ± 9.4 to 18.3 ± 8.2, p = .001) and based on mental (p = .047) and physical (p = .134) score of SF-12. Main additional dietary changes were reduced intake of energy, carbohydrates, and fiber. CONCLUSION: Our findings from this small-scaled pilot study indicate that the LFD may alleviate symptoms and improve HRQOL in patients with RE. Further controlled studies with larger sample size should be conducted to verify our results and hopefully enable implementation of LFD as a future part of the management strategy for RE.

BACKGROUND: Studies have found mercury to be associated with cardiovascular disease (CVD), however, primarily in populations with low exposure. The highest levels, and variations in the levels, of whole blood mercury (WBM) worldwide have been found in Greenland. We prospectively assessed the association between WBM and the risk of developing CVD in the Greenlandic population. METHODS: We assessed the effects of WBM levels on incident CVD among 3083 Greenlandic Inuit, participating in a population-based cohort study conducted from 2005 to 2010. WBM was measured at baseline. Participants were followed in the National Patient Registries for Denmark and Greenland and in the causes of death register for CVD events from inclusion in the study until CVD event, emigration, death or end of follow-up (30/9-2013). Using Cox regression analyses, we calculated the incidence rates and the hazard ratio of CVD events according to WBM levels. Potential interactions with sex were also investigated. RESULTS: The highest levels of WBM were found in men, who had a significantly higher median level (19⯵g/L (IQR:1-44)), compared with women (15⯵g/L (IQR: 1-32), (pâ¯<â¯0.001)). The crude hazard ratio (HR) for incident CVD was 1.00 (95% CI 1.00-1.00) for 5⯵g/l increase in WBM. After adjusting for several potential confounders, there was still no association between WBM and incident CVD (HR 0.99; 95%CI:0.99-1.00). We found no interactions with sex. CONCLUSIONS: In a population with high levels of WBM, we found no association between WBM and the risk of developing CVD in Greenland.

Cystatin C (CysC) is known to be related to cardiovascular disease (CVD), including the presence and severity of coronary artery disease (CAD) and future clinical events. In this study, the association between CysC levels and (1) coronary artery calcification (CAC) in asymptomatic individuals from the general population as well as (2) different subgroups of patients with suspected or definite acute myocardial infarction (MI) was investigated. CysC levels were measured in serum from asymptomatic individuals as part of a screening study for CAC using non-contrast cardiac CT scan (N = 1039) as well as in subgroups of hospitalized patients with a suspected MI (N = 769). CysC was not associated with CAC in asymptomatic individuals after adjusting for relevant risk factors. No difference in CysC levels was observed between patients with type 1 MI (1.07 mg/L) and patients with normal troponin (with or without prior CAD: 1.14 and 1.01 mg/L, respectively). However, patients with type 2 MI and patient subgroups with elevated troponin but without MI had significantly higher CysC levels (1.24, 1.23 and 1.31 mg/L), even after adjusting for other risk factors. CysC was not associated with CAC in middle-aged asymptomatic individuals from the general population. Furthermore, CysC levels were found to be significantly lower in patients with type 1 MI compared to patients with type 2 MI and patients with elevated troponins but without MI. Thus, in two independent and clinically different populations, no association between CysC and coronary atherosclerotic manifestations could be demonstrated.

Measurement of ionized calcium (CaI) has been reported to be dependent on albumin concentration. We examined the correlation between albumin and CaI measured on different ion selective electrode analyzers and in different groups of patients in a large dataset, extracted from the laboratory information system. In 17,281 outpatients and 16,194 inpatients, significantly positive correlations were found between CaI and albumin, with changes in CaI per 10 g/L change in albumin ranging from 0.007-0.043 mmol/L and 0.017-0.028 mmol/L, respectively. Correlations were found to be significantly different when using different analyzers. In order to examine whether the difference in correlations between the analyzers were really due to different patient populations investigated on the different analyzers, data analyzed on the same type of analyzer from inpatients from four different wards (intensive care unit, medical ward, surgical ward and orthopedic ward) were examined. There was no significant difference in correlations between patients from the four wards. Although, these results points towards technical causes behind the observed differences it cannot be entirely ruled out that clinical diseases or treatment might influence albumin interaction with CaI measurements. Combining all data from both out- and inpatients, a correction formula using a change in CaI of 0.03 mmol/L per 10 g/L change in albumin, was constructed. However, the albumin influence on CaI is only a minor part of the total CaI variation and, in most situations, the relatively small effect of changes in albumin on CaI-results is most likely of no clinical importance.

BACKGROUND: Incidence of and risk factors for bleeding in cancer patients with venous thromboembolism (VTE) treated with apixaban are poorly described. METHODS: We analyzed data from the prospective CAP study where 298 cancer patients with any type of VTE received 5 mg apixaban twice daily for 6 months, and then 2.5 mg apixaban twice daily for 30 months. For most analyses, major bleedings and clinically relevant nonmajor bleedings were merged to "clinically relevant bleedings." Risk factors were estimated by odds ratios (OR) and 95% confidence intervals (CIs). RESULTS: The incidence of clinically relevant bleedings was 38% per person-year during the first 6 months of treatment, 21% per person-year from 7 to 12 months, and between 4 and 8% per person-year from 13 to 36 months. Clinically relevant bleedings were associated with age above 74 years (OR: 2.0, 95% CI: 1.0-4.1), body mass index (BMI) below 21.7 (OR: 2.3, 95% CI: 1.1-4.8), and hemoglobin at baseline below 10.5 for females (OR: 2.8, 95% CI: 1.1-7.3) and 11.1 for males (OR: 3.3, 95% CI: 1.3-8.4) during the first 6 months. Gastrointestinal (GI) or urogenital cancer was not associated with clinically relevant bleedings compared with other cancers. Among patients with luminal GI cancer, nonresected cancer had increased risk of bleeding (OR: 3.4, 95% CI: 1.0-11.6) compared with resected GI cancer. CONCLUSION: There were very few bleedings while patients were on low-dose apixaban. Factors associated with bleeding in patients treated with full-dose apixaban were high age, low BMI, and low hemoglobin, and probably nonresected luminal GI cancer.

AIMS: Patients with inflammatory joint diseases (IJD), including rheumatoid arthritis (RA), psoriatic arthritis (PsA), and axial spondyloarthritis (axSpA) have increased rates of pulmonary embolism (PE). Non-steroidal anti-inflammatory drugs (NSAIDs) use is associated with PE in the general population. Our aim was to evaluate the association between NSAIDs use and PE in IJD patients. METHODS AND RESULTS: Using individual-level registry data from the whole Norwegian population, including data from the Norwegian Patient Registry and the Norwegian Prescription Database, we: (1) evaluated PE risk in IJD compared to non-IJD individuals, (2) applied the self-controlled case series method to evaluate if PE risks were associated with use of traditional NSAIDs (tNSAIDs) and selective cox-2 inhibitors (coxibs). After a one-year wash-out period, we followed 4 660 475 adults, including 74 001 with IJD (RA: 39 050, PsA: 20 803, and axSpA: 18 591) for a median of 9.0 years. Crude PE incidence rates per 1000 patient years were 2.02 in IJD and 1.01 in non-IJD individuals. Age and sex adjusted hazard ratios for PE events were 1.57 for IJD patients compared to non-IJD. Incidence rate ratios (IRR) [95% confidence interval (CI)] for PE during tNSAIDs use were 0.78 (0.64-0.94, P = 0.010) in IJD and 1.68 (1.61-1.76, P < 0.001) in non-IJD. IRR (95% CI) for PE during coxibs use was 1.75 (1.10-2.79, P = 0.018) in IJD and 2.80 (2.47-3.18, P < 0.001) for non-IJD. CONCLUSION: Pulmonary embolism rates appeared to be higher in IJD than among non-IJD subjects in our study. Traditional NSAIDs may protect against PE in IJD patients, while coxibs may associated with increased PE risk.

Background: Retina fundus images conducted in Greenland are telemedically assessed for diabetic retinopathy by ophthalmological nurses in Denmark. Applying an AI grading solution, in a Greenlandic setting, could potentially improve the efficiency and cost-effectiveness of DR screening.Method: We developed an AI model using retina fundus photos, performed on persons registered with diabetes in Greenland and Denmark, using Optos® ultra wide-field scanning laser ophthalmoscope, graded according to ICDR.Using the ResNet50 network we compared the model's ability to distinguish between different images of ICDR severity levels in a confusion matrix.Results: Comparing images with ICDR level 0 to images of ICDR level 4 resulted in an accuracy of 0.9655, AUC of 0.9905, sensitivity and specificity of 96.6%.Comparing ICDR levels 0,1,2 with ICDR levels 3,4, we achieved a performance with an accuracy of 0.8077, an AUC of 0.8728, a sensitivity of 84.6% and a specificity of 78.8%. For the other comparisons, we achieved a modest performance.Conclusion: We developed an AI model using Greenlandic data, to automatically detect DR on Optos retina fundus images. The sensitivity and specificity were too low for our model to be applied directly in a clinical setting, thus optimising the model should be prioritised.

In this article, we show how a particular biomarker comes into being in an emergency department in a hospital in Copenhagen, Denmark. We explore the contextual becoming of this biomarker, suPAR, through interviews with nurses and physicians and through relational ontology. We find that as a prognostic biomarker suPAR is challenged in it becoming as an object for clinical practice in the emergency department by the power of diagnostic practices and the desire for experience-based scripts that quickly enable the clinician to reach the right diagnosis. Although suPAR is enacted as a promising triage strategy suggesting a low or high risk of disease, the inability to rule out specific diagnoses and producing the notion of secure clinical actions make its non-specificity and prognostic character problematic in clinical practices. Specific diagnostic criteria versus prognostic interpretation and non-specificity risk profiling challenges the way healthcare workers in an emergency department understand the tasks they are set to solve and how to solve them. We discuss how the becoming of suPAR is strengthened through enactments of specificity and engagement in triage strategies and we reflect on it's becoming through new diagnostic practices with the need to accommodate diagnostic ambiguity.
