A novel genus of Pectobacterium bacteriophages display broad host range by targeting several species of Danish soft rot isolates.

The bacterial diseases black leg and soft rot in potatoes cause heavy losses of potatoes worldwide. Bacteria within the genus Pectobacteriaceae are the causative agents of black leg and soft rot. The use of antibiotics in agriculture is heavily regulated and no other effective treatment currently exists, but bacteriophages (phages) have shown promise as potential biocontrol agents. In this study we isolated soft rot bacteria from potato tubers and plant tissue displaying soft rot or black leg symptoms collected in Danish fields. We then used the isolated bacterial strains as hosts for phage isolation. Using organic waste, we isolated phages targeting different species within Pectobacterium. Here we focus on seven of these phages representing a new genus primarily targeting P. brasiliense; phage Ymer, Amona, Sabo, Abuela, Koroua, Taid and Pappous. TEM image of phage Ymer showed siphovirus morphotype, and the proposed Ymer genus belongs to the class Caudoviricetes, with double-stranded DNA genomes varying from 39 kb to 43 kb. In silico host range prediction using a CRISPR-Cas spacer database suggested both P. brasiliense, P. polaris and P. versatile as natural hosts for phages within the proposed Ymer genus. A following host range experiment, using 47 bacterial isolates from Danish tubers and plants symptomatic with soft rot or black leg disease verified the in silico host range prediction, as the genus as a group were able to infect all three Pectobacterium species. Phages did, however, primarily target P. brasiliense isolates and displayed differences in host range even within the species level. Two of the phages were able to infect two or more Pectobacterium species. Despite no nucleotide similarity with any phages in the NCBI database, the proposed Ymer genus did share some similarity at the protein level, as well as gene synteny, with currently known phages. None of the phages encoded integrases or other genes typically associated with lysogeny. Similarly, no virulence factors nor antimicrobial resistance genes were found, and combined with their ability to infect several soft rot-causing Pectobacterium species from Danish fields, demonstrates their potential as biocontrol agents against soft rot and black leg diseases in potatoes.

How best to support parents in the management of standing frame usage in home settings: A mixed methods study.

BACKGROUND: An improved understanding of the current practice of standing frame use may have implications for supporting parents in managing standing frames. We aimed to investigate how parents of children with cerebral palsy perceive and manage standing frame use in home settings. METHODS: We conducted a mixed methods study with an explanatory sequential design, first collecting and analysing quantitative questionnaire data and then using these results to inform a qualitative follow-up phase to explain them. The questionnaire was answered by 103 parents of children with cerebral palsy across five countries, Denmark, Norway, Great Britain, Canada and the United States, and 12 Danish families participated in the subsequent interviews. A descriptive analysis was conducted using the questionnaire data. The qualitative data were analysed using a directed content analysis, enabling integration of the quantitative and qualitative data. RESULTS: The quantitative analysis showed that 89% of the parents felt confident with their child's standing frame, and 82% felt they had sufficient knowledge about how their child's standing frame could/should be used. However, the qualitative analysis showed that even when feeling confident, the parents experienced insecurity regarding whether their child was positioned correctly, and being responsible for positioning was challenging. CONCLUSION: Our study implies a need for providing educational materials to assist the parents in ensuring optimal positioning of their child in the standing frame to decrease insecurity. Additionally, our study suggests a need to provide more thorough information about the benefits of using a standing frame and ensure alignment of expectations in relation to the child's prognosis of functional independence.

Covid-19 infection and vaccination during first trimester and risk of congenital anomalies: Nordic registry based study.

OBJECTIVES: To evaluate the risk of major congenital anomalies according to infection with or vaccination against covid-19 during the first trimester of pregnancy. DESIGN: Prospective Nordic registry based study. SETTING: Sweden, Denmark, and Norway. PARTICIPANTS: 343 066 liveborn singleton infants in Sweden, Denmark, and Norway, with an estimated start of pregnancy between 1 March 2020 and 14 February 2022, identified using national health registries. MAIN OUTCOME MEASURE: Major congenital anomalies were categorised using EUROCAT (European Surveillance of Congenital Anomalies) definitions. The risk after covid-19 infection or vaccination during the first trimester was assessed by logistic regression, adjusting for maternal age, parity, education, income, country of origin, smoking, body mass index, chronic conditions, and estimated date of start of pregnancy. RESULTS: 17 704 (5.2%) infants had a major congenital anomaly. When evaluating risk associated with covid-19 infection during the first trimester, the adjusted odds ratio ranged from 0.84 (95% confidence interval 0.51 to 1.40) for eye anomalies to 1.12 (0.68 to 1.84) for oro-facial clefts. Similarly, the risk associated with covid-19 vaccination during the first trimester ranged from 0.84 (0.31 to 2.31) for nervous system anomalies to 1.69 (0.76 to 3.78) for abdominal wall defects. Estimates for 10 of 11 subgroups of anomalies were less than 1.04, indicating no notable increased risk. CONCLUSIONS: Covid-19 infection and vaccination during the first trimester of pregnancy were not associated with risk of congenital anomalies.

Unraveling the metabolomic architecture of autism in a large Danish population-based cohort.

BACKGROUND: The prevalence of autism in Denmark has been increasing, reaching 1.65% among 10-year-old children, and similar trends are seen elsewhere. Although there are several factors associated with autism, including genetic, environmental, and prenatal factors, the molecular etiology of autism is largely unknown. Here, we use untargeted metabolomics to characterize the neonatal metabolome from dried blood spots collected shortly after birth. METHODS: We analyze the metabolomic profiles of a subset of a large Danish population-based cohort (iPSYCH2015) consisting of over 1400 newborns, who later are diagnosed with autism and matching controls and in two Swedish population-based cohorts comprising over 7000 adult participants. Mass spectrometry analysis was performed by a timsTOF Pro operated in QTOF mode, using data-dependent acquisition. By applying an untargeted metabolomics approach, we could reproducibly measure over 800 metabolite features. RESULTS: We detected underlying molecular perturbations across several metabolite classes that precede autism. In particular, the cyclic dipeptide cyclo-leucine-proline (FDR-adjusted p = 0.003) and the carnitine-related 5-aminovaleric acid betaine (5-AVAB) (FDR-adjusted p = 0.03), were associated with an increased probability for autism, independently of known prenatal and genetic risk factors. Analysis of genetic and dietary data in adults revealed that 5-AVAB was associated with increased habitual dietary intake of dairy (FDR-adjusted p < 0.05) and with variants near SLC22A4 and SLC22A5 (p < 5.0e - 8), coding for a transmembrane carnitine transporter protein involved in controlling intracellular carnitine levels. CONCLUSIONS: Cyclo-leucine-proline and 5-AVAB are associated with future diagnosis of autism in Danish neonates, both representing novel early biomarkers for autism. 5-AVAB is potentially modifiable and may influence carnitine homeostasis.

Pregnancy As Window of Opportunity? A Danish RCT on Physical Activity During Pregnancy.

Pregnancy is seen as a window of opportunity for health interventions, with the potential to produce long-term health changes for mother and child. The RCT FitMum investigates the effects of different regimes of physical activity during pregnancy. We suggest that rather than hitting a window of opportunity, the trial works in choreography with different timescapes through the processes of management of time. These timescapes are characterized by linear progression and futurity, alongside composite, complex time. We reconceptualize the intervention as a navigation of flows and passages in collective efforts, providing a situated and sustainable approach to interventions.

Making it Work: Everyday Life and Healthcare with Multiple Chronic Illnesses in Denmark.

A growing concern in clinical literature with the "treatment burden" of living with multimorbidity raises questions about how we can study and produce knowledge on the impact of health care. In this article, we draw on ethnographic material from fieldwork among people with multimorbidity in Denmark and recent theorization on "values" in health care, to show how an ongoing "trying out" and ways of "just getting on with it" are enacted in illness trajectories marked by multimorbidity. Our findings point to the importance of attending to the subject positions that particular healthcare relations and encounters make possible.

Midazolam Indications and Dosing in Palliative Medicine: Results from a Multinational Survey.

Despite sparse evidence and limited guidance on indications, use, and dosing, midazolam is widely used in palliative care. We aimed to describe and compare the use of midazolam in three different countries to improve clinical practice in palliative care. We performed an online survey among palliative care physicians in Norway, Denmark, and the United Kingdom (UK). The focus was indications, dosing, administration, and concomitant drugs. A web-based questionnaire was distributed to members of the respective national palliative medicine associations. The total response rate was 9.4%. Practices in the UK, Norway, and Denmark were overall similar regarding the indications of midazolam for anxiety, dyspnoea, and pain treatment in combination with opioids. However, physicians in the UK used a higher starting dose for anxiety, dyspnoea, and pain treatment compared to Norway and Denmark, as well as a higher maximum dose. Danish physicians preferred, to a higher degree, on-demand midazolam administration. Despite practice similarities in the UK, Norway, and Denmark, differences exist for midazolam dosing and administration in palliative medicine. We demonstrated a lack of consensus on how midazolam should be used in palliative care, setting the stage for future studies on the topic.

Body Fit With a Pouching System With Concave Contour for People With an Outward Peristomal Body Profile: Effects on Leakage, Wear Time, and Quality of Life: A Randomized Controlled Cross-Over Trial.

PURPOSE: The purpose of the study was to investigate the fit of a two-piece pouching system with a concave-shaped skin barrier on people with an outward peristomal body profile and its effect on leakage, wear time, and quality of life (QoL) related to using an ostomy product. DESIGN: Randomized, controlled, open-label, cross-over trial. SUBJECTS AND SETTINGS: The sample comprised 53 subjects with outward peristomal body profiles and problems with leakage of ostomy effluent from their pouching system. Participants were randomized to the concave two-piece pouching system or a comparator (two-piece pouching system with a flat skin barrier) for 3 weeks. Subjects were then crossed over to the opposite skin barrier for an additional 3 weeks. The study was conducted in Denmark, Norway, Germany, and the Netherlands; data were collected in multiple ambulatory clinics or during home visits. METHODS: The primary end point was the ability of the skin barrier to fit body contours; secondary outcomes were leakage of effluent from the pouching system, wear time, and QoL related to using an ostomy product via the validated Ostomy-Q questionnaire. Primary comparisons between concave and comparator pouching systems were evaluated using proportional odds models and mixed models taking test period into account. RESULTS: Analysis included randomized subjects who had been exposed to at least one product and with information on at least one end point (full-analysis-set, n = 52). The concave pouching system provided a better fit to body contours than the comparator (P< .001) and reduced the degree of leakage underneath the skin barrier (LS mean difference = -1.84, 95% CI -3.31 to -0.37; P = .016). Participants experienced fewer episodes of leakage outside the skin barrier when using concave versus comparator pouching system (13.0% vs. 26.7%, respectively). Participants reported significant improvements in QoL (LS mean difference = 14.3; 95% CI 9.4 to 19.2; P < .001). No significant difference in wear time between skin barrier shapes was reported. CONCLUSIONS: Study findings indicate that a pouching system with a concave skin barrier achieved a better body fit on people with an outward peristomal body profile and resulted in fewer leakage incidents and higher QoL compared to using a pouching system with a flat skin barrier.

Potential of the Danish Comorbidity Index for Acute Myocardial Infarction to discriminate mortality in patients with infective endocarditis.

INTRODUCTION: Current risk score models for predicting mortality in infective endocarditis (IE) include data often unavailable in registries, limiting their use for confounding adjustment in population-based research. METHODS: This study assessed the Danish Comorbidity Index for Acute Myocardial Infarction (DANCAMI) for its ability to predict 30-day, 1-year, and 5-year mortality in IE patients, compared to the Charlson Comorbidity Index (CCI) and Elixhauser Comorbidity Index (ECI). The study included all adult Danish patients with first-time IE from 1995 to 2021. The area under the receiver operating characteristic curve (AUC) was estimated using logistic regression to measure discriminatory performance for all-cause and cardiovascular mortality at the specified time intervals. A baseline model included age and sex, while extended models incorporated continuous comorbidity scores. RESULTS: We identified 8966 patients with IE. Mortality rates were 12% at 30 days, 26% at 1 year, and 36% at 5 years. For all-cause mortality, AUCs for the baseline versus DANCAMI models were 0.64 vs. 0.69 at 30 days, 0.66 vs. 0.73 at 1 year, and 0.72 vs. 0.79 at 5 years. For cardiovascular mortality, AUCs for baseline versus DANCAMI models were 0.67 vs. 0.69 at 30 days, 0.67 vs. 0.69 at 1 year, and 0.70 vs. 0.71 at 5 years. CCI and ECI demonstrated comparable AUCs to the DANCAMI model. CONCLUSION: DANCAMI improved discrimination of short- and long-term mortality in IE patients and may be used for confounder adjustment similarly to CCI and ECI.

Magnetic Resonance Imaging Signs of Idiopathic Intracranial Hypertension.

Importance: The magnetic resonance imaging (MRI) criteria currently used to diagnose idiopathic intracranial hypertension (IIH) are based on expert opinion and have limited accuracy. Additional neuroimaging signs have been proposed and used with contradictory results; thus, prospective evidence is needed to improve diagnostic accuracy. Objective: To provide evidence-based, accurate MRI signs for IIH diagnosis. Design, Setting, and Participants: This prospective cohort study was conducted from January 2018 to May 2021 with 3 validation cohorts at 2 Danish headache centers and with 3 independent international cohorts. Consecutive patients with suspected IIH were enrolled. Eligibility required the clinical suspicion of IIH, age 18 years or older, and written informed consent. The validation cohorts comprised patients with confirmed IIH from Austria and the US, and patients without IIH from the US. Data analysis was performed from December 2021 to August 2023. Exposure: Standardized diagnostic workup was performed to classify cases according to current criteria, and blinded evaluation of cerebral radiological diagnostics and papilledema was performed. Main Outcomes and Measures: The primary outcomes were MRI signs associated with IIH as assessed by univariate analyses. An MRI score estimating papilledema was calculated using machine learning. Internal validation of associations with lumbar puncture opening pressure and outcome and external validation of accuracy were performed in 3 cohorts. Results: Of 192 eligible patients (185 women [96.4%]; median [IQR] age, 28.0 [23.0-35.0] years), 110 were classified as having IIH, 4 as having probable IIH, and 1 as having suspected IIH without papilledema; 77 did not have IIH and served as controls, with corresponding age, sex, and weight. Papilledema at diagnosis was associated with perioptic subarachnoid space distension (56 patients [68.3%] vs 21 patients [41.2%]), posterior globe flattening (53 patients [66.3%] vs 10 patients [21.3%]), optic nerve disc protrusion (35 patients [30.4%] vs 2 patients [2.3%]), and transverse sinus venous stenosis (75 patients [79.8%] vs 29 patients [46.8%]). The papilledema-estimating MRI score showed optimal balance between sensitivity (49%) and specificity (87%) when 2 of the 3 latter signs were present and was associated with the lumbar puncture opening pressure and ophthalmological outcome. The score showed strong diagnostic accuracy in the external validation cohorts (587 patients; area under the receiver operating characteristic curve, 0.86) and outperformed the current (2013) diagnostic MRI criteria. Conclusions and Relevance: The findings of this cohort study of patients with IIH and controls suggest that an evidence-based MRI score including posterior globe flattening, optic nerve disc protrusion, and transverse sinus stenosis can estimate the presence of papilledema more accurately than the current diagnostic criteria.

Outbreak of equine herpesvirus 4 (EHV-4) in Denmark: tracing patient zero and viral characterization.

BACKGROUND: Equine herpesvirus 4 (EHV-4) causes respiratory disease in horses, and the virus is considered endemic in the global equine population. However, outbreaks can occur when several horses are gathered in relation to shows, competitions, breeding units and at hospitals. In the spring year 2022, an EHV-4 outbreak occurred at the Large Animal Teaching Hospital, University of Copenhagen, Denmark. Nine horses were tested EHV-4 positive during the outbreak, which lasted approx. seven weeks. In addition, a tenth horse "Eq10" tested EHV-4 positive almost three weeks after the last of the outbreak horses tested positive. Detailed clinical registrations were obtained from all ten horses as well as their location and movement during hospitalization. Nasal swabs were obtained throughout the outbreak and tested by qPCR for EHV-4. Additionally, pre- and post-infection sera were tested for the presence of EHV-4 antibodies. Selected samples were characterized by partial and full genome sequencing. RESULTS: The most common clinical signs of the EHV-4 infected horses during this outbreak were pyrexia, nasal discharge, mandibular lymphadenopathy and increased lung sounds upon auscultation. Based on the locations of the horses, EHV-4 detection and antibody responses the most likely "patient zero" was identified as being "Eq1". Partial genome sequencing revealed that Eq10 was infected by another wild type EHV-4 strain, suggesting that the hospital was able to eliminate the outbreak by testing and reinforcing biosecurity measures. The complete genome sequence of the outbreak strain was obtained and revealed a closer relation to Australian and Japanese EHV-4 strains rather than to other European EHV-4 strains, however, very limited sequence data are available from Europe. CONCLUSION: The study illustrated the transmission of EHV-4 within an equine facility/hospital and provided new insights into the viral shedding, antibody responses and clinical signs related to EHV-4 infections. Finally, sequencing proved a useful tool in understanding the transmission within the hospital, and in characterizing of the outbreak strain.

Literary tastes are as heritable as other human phenotypes: Evidence from twins' library borrowing.

Social science research argues that differences in individuals' literary and cultural tastes originate in social environments. Yet, it might be that these differences are partly associated with genetic differences between individuals. To address this possibility, we use nation-scale registry data on library borrowing among Danish twins (N = 67,900) to assess the heritability of literary tastes. We measure literary tastes via borrowing of books of different genres (e.g., crime and biographical novels) and formats (physical, digital, and audio) and decompose the total variance in literary tastes into components attributable to shared genes (heritability), shared environments (social environment shared by siblings), and unique environments (social environments not shared by siblings). We find that genetic differences account for 45-70 percent of the total variance in literary tastes, shared environments account for almost none of the variance, and unique environments account for a moderate share. These results suggest that literary tastes are approximately as heritable as other human phenotypes (e.g., physical traits, cognition, and health). Moreover, heritability is higher for socioeconomically disadvantaged groups than for advantaged groups. Overall, our results suggest that research should consider the role of genetic differences in accounting for individual differences in literary and broader cultural tastes.

Adjusting the 15-method to Danish general practice: identification of barriers, facilitators, and user needs.

BACKGROUND: The 15-method is an opportunistic screening and brief intervention tool for alcohol-related problems in primary healthcare. A Danish feasibility study of the 15-method indicated that adjustments were needed to improve its contextual fit to Danish general practice. This adjustment process was conducted in two parts. The first part focused on identifying barriers, facilitators, and user needs for addressing alcohol using the 15-method. The second part will address the identified barriers and user needs to finalize a Danish version of the method. This study reports on part one of the adjustment process. METHODS: Semi-structured individual interviews and focus group interviews with healthcare professionals (n = 8) and patients (n = 5) from general practice in Denmark. Data analysis was conducted using thematic content analysis. The results were condensed into two focus areas that will form the basis for user workshops in part two of the adjustment process. RESULTS: The main barriers for addressing alcohol using the 15-method were patients and healthcare professionals not having the same agenda, having difficulty opening a conversation on alcohol, and workflow in the practices. Main facilitators included high interpersonal skills, taking the patient's perspective, and good routines and interdisciplinary work. Suggested adjustments and additions to the method included digitalization, visual icebreakers, quotes and examples, and development of a quick guide. The identified focus areas for user workshops were Communication and Material, and Integration to Workflows. CONCLUSION: Healthcare professionals found the opportunistic screening approach exemplified by the 15-method to be beneficial in identifying and addressing alcohol-related problems. They appreciate the method's structured framework that assists in presenting treatment options. Identified adjustment areas to the 15-method will lay the groundwork for future efforts to develop a finalized Danish version of the 15-method.

Discontinuing the recommendation of hip precautions does not increase the risk of early dislocation after primary total hip arthroplasty using 36-mm heads: a population-based study from the Danish Hip Arthroplasty Register.

BACKGROUND AND PURPOSE: Dislocation is a severe complication following total hip arthroplasty (THA). Hip precautions have been recommended in the initial postoperative period but evidence supporting this practice is limited. We therefore conducted a population-based study to evaluate the association between discontinuing recommending postoperative hip precautions and the risk of early dislocation. METHODS: This is a cohort study with data from the Danish Hip Arthroplasty Register and the Danish National Patient Register. We included patients who underwent primary THA for osteoarthritis in 2004-2019 in public hospitals in the Capital Region of Denmark. The cohort was divided into the hip precautions group, comprising patients operated on between 2004 and 2009, and the no-precautions group operated on between 2014 and 2019. The primary outcome was the difference in the absolute risk of dislocation within 3 months post-surgery. The secondary outcome assessed the same risk within 2 years. We evaluated the difference in absolute risk using absolute risk regression (ARR). RESULTS: The cumulative incidence of dislocation within 3 months was 2.9% (confidence interval [CI] 2.5-3.3) in the hip precautions group and 3.5% (CI 3.1-3.9) in the no-precautions group. The risk of dislocation was higher in the no-precautions group but failed to reach statistical significance in the crude (ARR 1.2, CI 0.9-1.6) and multivariate model (ARR 1.4, CI 0.9-2.2). CONCLUSION: We found a higher but statistically insignificant increase in the risk of early dislocation in the no-precautions group. The lack of significance in the association may be explained by the increased use of 36-mm femoral heads after the guideline revision.

Colorectal cancer and association with anaerobic bacteraemia: A Danish nationwide population-based cohort study.

OBJECTIVES: We aimed to identify specific anaerobic bacteria causing bacteraemia and a subsequent diagnosis of colorectal cancer. METHODS: A nationwide population-based cohort study, which included all episodes of defined specific anaerobic bacteraemia from 2010 (5,534,738 inhabitants) through 2020 (5,822,763 inhabitants) and all cases of colorectal cancer diagnosed from 2010 through 2021 in Denmark. We calculated the incidence and risk of colorectal cancer after bacteraemia with specific anaerobic bacteria using Escherichia coli bacteraemia as reference. RESULTS: Nationwide data on colorectal cancer and specific anaerobic bacteraemia (100% complete, representing 11,124 episodes). The frequencies of colorectal cancer within one year following anaerobic bacteraemia were higher for species, which almost exclusively reside in the colon, such as Phocaeicola vulgatus/dorei (5.5%), Clostridium septicum (24.2%), and Ruminococcus gnavus (4.6%) compared to 0.6% in 50,650 E. coli bacteraemia episodes. Bacteroides spp. had a subhazard ratio for colorectal cancer of 3.9 (95% confidence interval [CI], 3.0 to 5.1) and for Clostridium spp. it was 8.9 (95% CI, 6.7 to 11.8, with C. septicum 50.0 [95% CI, 36.0 to 69.5]) compared to E. coli (reference). CONCLUSION: This nationwide study identified specific colorectal cancer-associated anaerobic bacteria, which almost exclusively reside in the colon. Bacteraemia with these bacteria could be an indicator of colorectal cancer.

Short-term and long-term stroke risk following SARS-CoV-2 infection in relation to disease severity: a Danish national cohort study.

OBJECTIVES: Studies have reported high incidences of stroke in patients hospitalised with SARS-CoV-2, but the impact of disease severity is unexplored. We aimed to estimate the risk of incident ischaemic stroke in SARS-CoV-2 test-positive individuals compared with test-negative individuals stratified by disease severity during acute infection and post infection. DESIGN: A register-based cohort study. SETTING: A Danish nationwide study. PARTICIPANTS: All Danish adults who had PCR tests for SARS-CoV-2 performed between 1 March 2020 and 30 November 2021. Test-positive individuals were included at their first positive test. For individuals tested prior to 30 November 2021, we randomly sampled an index date from the distribution of test dates among SARS-CoV-2 test-positive individuals. Test-positive individuals were followed during the acute phase of infection (days 0-14) and post infection (180 days after the acute phase). Test-negative individuals were followed in equivalent time periods. PRIMARY AND SECONDARY OUTCOME MEASURES: Incident ischaemic stroke risk in SARS-CoV-2 test-positive individuals compared with test-negative individuals during acute infection and post infection. We calculated subdistribution HRs (SHR) with death as a competing risk using propensity score weighting as confounder control. The risk was stratified according to disease severity: community managed, hospitalised, or admission to the intensive care unit. RESULTS: Among 3 910 219 SARS-CoV-2 PRC-tested individuals, 356 421 test-positive and 3 067 456 test-negative individuals were included. A positive SARS-CoV-2 test was associated with an SHR of 3.32 (95% CI 2.60 to 4.25) overall for stroke compared with test negative in the acute phase. In the postinfection period, the risk of stroke remained increased in individuals hospitalised during the acute phase (SHR 1.85, 95% CI 1.45 to 2.37). Individuals with community-managed SARS-CoV-2 had no increased long-term risk of stroke (SHR 1.01, 95% CI 0.88 to 1.16). CONCLUSION: SARS-CoV-2 infection is associated with increased stroke risk. Disease severity seems to be an important factor. Individuals with community-managed SARS-CoV-2 had no increased stroke risk.

A danish healthcare-focused economic evaluation of first-line cryoballoon ablation versus antiarrhythmic drug therapy for the treatment of paroxysmal atrial fibrillation.

INTRODUCTION: Three randomised controlled trials (RCTs) have demonstrated that first-line cryoballoon pulmonary vein isolation decreases atrial tachycardia in patients with symptomatic paroxysmal atrial fibrillation (PAF) compared with antiarrhythmic drugs (AADs). The aim of this study was to develop a cost-effectiveness model (CEM) for first-line cryoablation compared with first-line AADs for the treatment of PAF. The model used a Danish healthcare perspective. METHODS: Individual patient-level data from the Cryo-FIRST, STOP AF and EARLY-AF RCTs were used to parameterise the CEM. The model structure consisted of a hybrid decision tree (one-year time horizon) and a Markov model (40-year time horizon, with a three-month cycle length). Health-related quality of life was expressed in quality-adjusted life years (QALYs). Costs and benefits were discounted at 3% per year. Model outcomes were produced using probabilistic sensitivity analysis. RESULTS: First-line cryoablation is dominant, meaning it results in lower costs (-€2,663) and more QALYs (0.18) when compared to first-line AADs. First-line cryoablation also has a 99.96% probability of being cost-effective, at a cost-effectiveness threshold of €23,200 per QALY gained. Regardless of initial treatment, patients were expected to receive ∼ 1.2 ablation procedures over a lifetime horizon. CONCLUSION: First-line cryoablation is both more effective and less costly (i.e. dominant), when compared with AADs for patients with symptomatic PAF in a Danish healthcare system.

Impact of decentralized management on sickness absence in hospitals: a two-wave cohort study of frontline managers in Danish hospital wards.

BACKGROUND: This study explores the impact of decentralized management on the sickness absence among healthcare professionals. Sickness absence is a reliable indicator of employees' wellbeing and it is linked to management quality. However, the influence of decentralized management on sickness absence has not been adequately studied. METHODS: The research design combined a two-wave, web-survey of frontline managers in two Danish university hospitals with administrative data on sickness absence at the ward-level. The first and second wave included data from 163165 and 137 frontline managers linked to 121 wards and 108 wards. Data was analysed using an ordinal logistic regression model. RESULTS: Wards where frontline managers had the highest level of decentralised decision authority compared to none showed lower odds of ward-level sickness absence (ORcrude: 0.20, 95% CI: 0.05-0.87). A very high extent of cross-functional decision authority showed lower odds of sickness absence (ORcrude: 0.08, 95% CI: 0.01-0.49). Overall, the results showed a clear data trend, although not all results were statistically significant. CONCLUSION: Higher levels of decentralized management in wards were positively associated with lower risks of sickness absence in hospital wards. The study supports future research on how to empower decision autonomy at the frontline level of management.

Exploring the course of functional somatic symptoms (FSS) from pre- to late adolescence and associated internalizing psychopathology - an observational cohort-study.

BACKGROUND: Functional somatic symptoms (FSS), which commonly cannot be attributed to well-defined organic pathology, often co-occur with internalizing psychopathology and fluctuate throughout different life stages. We examined FSS courses throughout adolescence, and the association between preadolescent FSS, FSS severity and internalizing psychopathology at late adolescence. METHODS: Data from the Copenhagen Child Cohort (CCC2000) were utilized from assessments at ages 11-12 years (preadolescence; T0) and 16-17 years (late adolescence; T1). Self-report questionnaire and interview data on FSS, internalizing psychopathology, chronic medical conditions, and sociodemographic data from Danish national registers were available for 1285 youths. FSS courses were categorized into persistent (high FSS at T0 & T1), remission (high FSS only at T0), incident (high FSS only at T1) or no FSS (no FSS at T0 & T1). Multiple linear and multinomial logistic regressions were conducted to investigate the FSS/psychopathology association. RESULTS: 1.8% of adolescents fell into the persistent FSS course group throughout adolescence. Higher preadolescent FSS predicted FSS (b = 0.07, p < .001), anxiety (b = 0.05, p < .001) and depression (b = 0.06, p < .001) at age 16/17, even after controlling for sex, parental education, a chronic medical condition and internalizing psychopathology in preadolescence. Persistent, incident, and remittent FSS courses were associated with significantly higher mean levels of anxiety and depression compared to the reference group (no FSS). CONCLUSIONS: FSS during pre- and late adolescence might increase and co-occur with anxiety and depression throughout adolescence, potentially due to shared underlying risk factors and processes.
