Background The congenital heart disease (CHD) population is growing and aging. We aim to examine the impact by describing the temporal trend and causes of lifetime hospitalization burden among the CHD population. Methods and Results From the Danish National Patient Registry, 23 141 patients with CHD and their hospitalizations from 1977 to 2018 were identified, excluding patients with extracardiac malformation. Patients with CHD were categorized into major CHD and minor CHD, and each patient was matched with 10 controls by sex and year of birth. The rate of all‐cause hospitalization increased over time from 28.3 to 36.4 hospitalizations per 100 person‐years (PY) with rate difference (RD) per decade of 2.5 (95% CI, 2.0–3.1) hospitalizations per 100 PY for the patients with CHD, compared with the increase from 10.8 to 17.0 per 100 PY (RD per decade, 2.0 [95% CI, 1.8–2.2] per 100 PY) for the control group (RD for CHD versus control, P=0.08). The all‐cause hospitalization rate remained constant for the major CHDs (RD per decade, −0.2 [95% CI, −1.2 to 0.9] per 100 PY) but increased for the minor CHDs (RD per decade, 5.2 [95% CI, 4.3–6.0] per 100 PY). For all patients with CHD, the cardiovascular hospitalization rate remained constant over time (RD per decade, 0.2 [95% CI, −0.3 to 0.6] per 100 PY) whereas the noncardiovascular hospitalization rate increased (RD per decade, 2.1 [95% CI, 1.6–2.7] per 100 PY). The length of all‐cause hospital stays for all patients with CHD decreased from 2.7 (95% CI, 2.6–2.8) days per PY in 1977 to 1987 to 1.6 (95% CI, 1.6–1.7) days per PY in 2008 to 2018. Conclusions Compared with previous decades, patients with CHD have an increasing hospitalization rate, similar to the general population, but a decreasing length of hospital stay. The increase in hospitalization rate was driven by noncardiovascular hospitalizations, with the patients with minor CHD being the key contributor to the increasing rate.

Introduction Multiple sclerosis (MS) causes a broad range of symptoms, with physical function being one of the most disabling consequences according to patients themselves. Exercise effectively improves lower extremity physical function. Nonetheless, it is unknown which exercise modality is most effective and it remains challenging to keep persons with MS adhering to exercise over a longer period. Therefore, the present study aims to investigate how exercise booster sessions (EBS) influence the sustainability of exercise-induced effects on physical function, and furthermore, to investigate which exercise modality (aerobic training or resistance training) is most effective in terms of improving physical function.Materials and methods This study is a multi-arm, parallel-group, open-label multicentre randomised controlled trial investigating the effects of EBS. Participants (n=150) are initially randomised to 12 weeks of either resistance training+usual care, aerobic training+usual care or usual care. After 12 weeks of intervention, participants in the exercise groups will again be randomised to either EBS+usual care or usual care during a 40-week follow-up period. The primary outcome is physical function (composite score based on 6-min walk test and five-time sit to stand), and the secondary outcomes are fatigue, cognition, physical activity, symptoms of depression and quality of life.Ethics and dissemination The study is approved by the Central Denmark Region Committees on Health Research Ethics (1-10-72-237-21) and is registered at the Danish Data Protection Agency (2016-051-000001) and at Clinicaltrials.gov (NCT04913012). All study findings will be published in scientific peer-reviewed journals and presented at scientific conferences.Trial registration number NCT04913012.

Summary: Background: Homelessness is associated with adverse health and social outcomes. People experiencing homelessness have been found to have a high risk of violent crime victimisation as well as high prevalence of psychiatric disorders. It is poorly understood whether experiencing homelessness is associated with additional risks of violent offending and whether psychiatric disorders contribute to these risks. We examined the association between homelessness, psychiatric disorders, and first violence offence leading to conviction. Methods: We did a nationwide, register-based cohort study of all Danish residents who were alive at least 1 day during the study period, born between Jan 1, 1980, and Dec 31, 2006, and aged 15 years or older retrieved from the Danish Civil Registration System, which was linked to registers with information on homelessness, health care, and criminality. The exposure was any experience of homelessness, which was defined as having at least one contact with a homeless shelter during the study period. The outcome was first violent offence leading to a conviction. We calculated incidence rates per 10 000 person-years, incidence rate ratios (IRRs) using Poisson regression analysis, and probability of conviction of a violent offence using an Aalen–Johansen estimator. Analyses were stratified by sex and adjusted for calendar year of the study period, age, other sociodemographic factors, and psychiatric disorders. Findings: The study cohort included 1 786 433 Danish residents aged 15–42 years living in Denmark at some point from Jan 1, 2001, to Dec 31, 2021, contributing to 21 336 322 person-years at risk, of whom 57 084 (3·2%) individuals had their first violent offence leading to conviction during follow-up. 10 years after their first contact with a homeless shelter, 22·9% (95% CI 21·6–24·2) of men and 7·7% (6·8–8·7) of women had committed at least one violent crime leading to conviction. The fully adjusted IRRs of a violent offence leading to conviction were 4·8 (4·5–5·1) in men and 6·3 (5·6–7·2) in women experiencing homelessness compared with individuals who had not experienced homelessness. The IRR for a violent offence leading to conviction was highest in individuals experiencing homelessness and having co-occurring psychiatric disorders compared with those not experiencing homelessness and without co-occurring psychiatric disorders, especially drug use disorders (IRR in those experiencing homelessness and having a drug use disorder: 15·3 [14·1–16·7] in men and 40·1 [33·9–47·5] in women compared with individuals not experiencing homelessness and having no drug use disorder). Interpretation: Individuals experiencing homelessness had higher risks of a violent offence leading to conviction than those who had not experienced homelessness. In addition to preventing homelessness, public health and policy should consider how to reduce the risk of adverse outcomes in people experiencing homelessness. Funding: Lundbeck Foundation.

Purpose The SmartSleep Study is established to comprehensively assess the impact of night-time smartphone use on sleep patterns and health. An innovative combination of large-scale repeated survey information, high-resolution sensor-driven smartphone data, in-depth clinical examination and registry linkage allows for detailed investigations into multisystem physiological dysregulation and long-term health consequences associated with night-time smartphone use and sleep impairment.Participants The SmartSleep Study consists of three interconnected data samples, which combined include 30 673 individuals with information on smartphone use, sleep and health. Subsamples of the study population also include high-resolution tracking data (n=5927) collected via a customised app and deep clinical phenotypical data (n=245). A total of 7208 participants are followed in nationwide health registries with full data coverage and long-term follow-up.Findings to date We highlight previous findings on the relation between smartphone use and sleep in the SmartSleep Study, and we evaluate the interventional potential of the citizen science approach used in one of the data samples. We also present new results from an analysis in which we use 803 000 data points from the high-resolution tracking data to identify clusters of temporal trajectories of night-time smartphone use that characterise distinct use patterns. Based on these objective tracking data, we characterise four clusters of night-time smartphone use.Future plans The unprecedented size and coverage of the SmartSleep Study allow for a comprehensive documentation of smartphone activity during the entire sleep span. The study has been expanded by linkage to nationwide registers, which allow for further investigations into the long-term health and social consequences of night-time smartphone use. We also plan new rounds of data collection in the coming years.

BackgroundThis study aims to compare valve durability between transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (SAVR).MethodsWe conducted a systematic review and meta-analysis using data from randomized controlled trials (RCTs). The primary outcome was structural valve deterioration (SVD). Secondary outcomes were bioprosthetic valve failure, reintervention, effective orifice area (EOA), mean pressure gradient, and moderate–severe aortic regurgitation (AR, transvalvular and/or paravalvular).ResultsTwenty-five publications from seven RCTs consisting of 7,970 patients were included in the analysis with follow-up ranges of 2–8 years. No significant difference was found between the two groups with regard to SVD [odds ratio (OR) 0.72; 95% CI: 0.25–2.12]. The TAVI group was reported to exhibit a statistically significant higher risk of reintervention (OR 2.03; 95% CI: 1.34–3.05) and a moderate–severe AR (OR 6.54; 95% CI: 3.92–10.91) compared with the SAVR group. A trend toward lower mean pressure gradient in the TAVI group [(mean difference (MD) −1.61; 95% CI: −3.5 to 0.28)] and significant higher EOA (MD 0.20; 95% CI: 0.08–0.31) was noted.ConclusionThe present data indicate that TAVI provides a comparable risk of SVD with favorable hemodynamic profile compared with SAVR. However, the higher risk of significant AR and reintervention was demonstrated.Systematic Review RegistrationPROSPERO (CRD42022363060).

Alemtuzumab is a monoclonal antibody targeting CD52 on the surface of immune cells, approved for the treatment of active relapsing-remitting multiple sclerosis (RRMS). The purpose of this study was to analyze the repopulation of peripheral lymphocytes following alemtuzumab-induced lymphocyte depletion and investigate associations with disease activity and development of secondary autoimmunity. For this, blood samples were collected two years after initiation of alemtuzumab treatment and lymphocytes were subjected to a comprehensive flow cytometry analysis. Included in the study were 40 patients treated with alemtuzumab and 40 treatment-naïve patients with RRMS. Disease activity and development of secondary autoimmune disease was evaluated after three years of treatment. Our study confirms that alemtuzumab treatment profoundly alters the circulating lymphocyte phenotype and describes a reconstituted immune system characterized by T cell activation/exhaustion, an increased regulatory control of IL-17 producing effector T cells and CD20+ T cells, and a reduced control of B cells. There were no obvious associations between immune cell subsets and disease activity or development of secondary autoimmune disease during treatment with alemtuzumab. Our results indicate that the reconstituted immune response is skewed towards a more effective regulatory control of MS-associated proinflammatory T cell responses. Also, the enlarged pool of naïve B cells together with the apparent decrease in control of B cell activity may explain why alemtuzumab-treated patients retain the ability to mount a humoral immune response towards new antigens.

Objective: To discuss how methods to estimate heterogenous causal effects can be applied in Family Science and to supply empirical examples using the case of fatherhood and earnings. Background: Many questions important to family scientists do not focus on one‐size‐fits‐all average effects but rather on whether and how effects differ across groups. Recent methodological advances can assist this latter focus, offering new insights for theory and policy. Method: Using Danish administrative data on all men who entered fatherhood 2005–2016 and on men of comparable age who did not, we focus on two types of heterogeneity in effects. First, effect heterogeneity across observed and unobserved covariates; second, treatment effect heterogeneity across the distribution of outcome variables. Results: The fatherhood premium on annual labor income is, in fact, a fatherhood penalty on average and across most margins of heterogeneity. Substantial heterogeneity exists across observed and unobserved characteristics and across the distribution of labor market earnings, with results indicating larger penalties for lower earners and those least likely to become fathers. Conclusions: Effect heterogeneity in Family Science holds great potential to inform policy and theory. However, causal interpretations always require assumptions, and researchers must be vigilant that the assumptions they make are warranted for each specific application. [ABSTRACT FROM AUTHOR]

Background and Aims Transcatheter aortic valve implantation (TAVI) has become the first choice to treat older patients with severe symptomatic aortic stenosis (AS). This study aimed to compare TAVI with surgery in low-risk patients ≤75 years of age, including both tricuspid and bicuspid AS. Methods The Nordic Aortic Valve Intervention (NOTION)-2 trial enrolled and 1:1 randomized low-risk patients aged ≤75 years with severe symptomatic AS to TAVI or surgery. The primary endpoint was a composite of all-cause mortality, stroke, or rehospitalization (related to the procedure, valve, or heart failure) at 12 months. Results A total of 370 patients were enrolled with a mean age of 71.1 years and a median Society of Thoracic Surgeons risk score of 1.1%. A total of 100 patients had bicuspid AS. The 1-year incidence of the primary endpoint was 10.2% in the TAVI group and 7.1% in the surgery group [absolute risk difference 3.1%; 95% confidence interval (CI), −2.7% to 8.8%; hazard ratio (HR) 1.4; 95% CI, 0.7–2.9; P =.3]. Patients with TAVI, when compared to surgery, had lower risk of major bleeding and new-onset atrial fibrillation and higher risk of non-disabling stroke, permanent pacemaker implantation, and moderate or greater paravalvular regurgitation. The risk of the primary composite endpoint was 8.7% and 8.3% in patients with tricuspid AS (HR 1.0; 95% CI, 0.5–2.3) and 14.3% and 3.9% in patients with bicuspid AS (HR 3.8; 95% CI, 0.8–18.5) treated with TAVI or surgery, respectively (P for interaction =.1). Conclusions Among low-risk patients aged ≤75 years with severe symptomatic AS, the rate of the composite of death, stroke, or rehospitalization at 1 year was similar between TAVI and surgery. Transcatheter aortic valve implantation outcomes in young bicuspid AS patients warrant caution and should be further investigated. (NOTION-2, ClinicalTrials.gov , NCT02825134).

Background: Cystic echinococcosis is non-endemic in Denmark and primarily diagnosed in migrants from endemic areas. Here, we report a case of pulmonary cystic echinococcosis in a Danish woman with no history of longer-term stays abroad, only holiday travelling to tourist destinations. This is the first case reported in international literature from Denmark where the causative parasite was identified to species and genotype level. Case: A 27-year-old pregnant Danish woman was admitted for examination because of haemoptysis for three months.Chest X-ray and computed tomography revealed a cystic structure in the left lung and a left-sided thoracotomy was performed to remove the cyst. Postoperative histopathological examination revealed a hyaline membrane and protoscoleces. Subsequently, infection with Echinococcus granulosus was confirmed by molecular methods. The causative agent was further characterised as E. granulosus sensu stricto G1, which is not known to have an established life cycle in Denmark. It was concluded that the infection was most likely acquired during a tourist travel to an endemic country. The patient was treated with albendazole for four weeks. Conclusion: This case of pulmonary cystic echinococcosis in a person who had lived in Denmark and had history of only short-term tourist travelling abroad highlights that the disease may be acquired during tourist travelling. Thus, a diagnosis of cystic echinococcosis should be considered not only in migrants from endemic countries but also in travellers upon incidental findings of a lung or liver cysts. The case also exemplifies the importance of reaching a diagnosis at species and genotype level.

Patients with multiple sclerosis (MS) and spinal cord injury (SCI) commonly sustain central neuropathic pain (NP) and spasticity. Despite a lack of consistent evidence, cannabis-based medicine (CBM) has been suggested as a supplement treatment. We aimed to investigate the effect of CBM on NP and spasticity in patients with MS or SCI. We performed a randomized, double-blinded, placebo-controlled trial in Denmark. Patients aged ≥18 years with NP (intensity >3, ≤9 on a numerical rating scale (NRS0-10) and/or spasticity (>3 on NRS0-10) were randomized to treatment consisting of either delta-9-tetrahydrocannabinol (THC), cannabidiol (CBD), a combination of THC&CBD in maximum doses of 22.5 mg, 45 mg and 22.5/45 mg per day, respectively, or placebo. A baseline registration was performed before randomization. Treatment duration was six weeks followed by a one-week phaseout. Primary endpoints were the intensity of patient-reported NP and/or spasticity. Between February 2019 and December 2021, 134 patients were randomized (MS n = 119, SCI n = 15), where 32 were assigned to THC, 31 to CBD, 31 to THC&CBD, and 40 to placebo. No significant difference was found for: mean pain intensity (THC 0.42 (−0.54–1.38), CBD 0.45 (−0.47–1.38) and THC&CBD 0.16 (−0.75–1.08)), mean spasticity intensity (THC 0.24 (−0.67–1.45), CBD 0.46 (−0.74–1.65), and THC&CBD 0.10 (−1.18–1.39), secondary outcomes (patient global impression of change and quality of life), or any tertiary outcomes. We aimed to include 448 patients in the trial; however, due to COVID-19 and recruitment challenges, fewer were included. Nevertheless, in this four-arm parallel trial, no effect was found between placebo and active treatment with THC or CBD alone or in combination on NP or spasticity in patients with either MS or SCI. The trial was registered with the EU Clinical Trials Register EudraCT (2018-002315-98).

Background Little is known about the cause of death (CoD) in patients with transposition of the great arteries palliated with a Mustard or Senning procedure. The aim was to describe the CoD for patients with the Mustard and Senning procedure during short‐ (20 years) follow‐up after the operation. Methods and Results This is a retrospective, descriptive multicenter cohort study including all Nordic patients (Denmark, Finland, Norway, and Sweden) who underwent a Mustard or Senning procedure between 1967 and 2003. Patients who died within 30 days after the index operation were excluded. Among 968 patients with Mustard/Senning palliated transposition of the great arteries, 814 patients were eligible for the study, with a mean follow‐up of 33.6 years. The estimated risk of all‐cause mortality reached 36.0% after 43 years of follow‐up, and the risk of death was highest among male patients as compared with female patients (P=0.004). The most common CoD was sudden cardiac death (SCD), followed by heart failure/heart transplantation accounting for 29% and 27%, respectively. During short‐, mid‐, and long‐term follow‐up, there was a change in CoD with SCD accounting for 23.7%, 46.6%, and 19.0% (P=0.002) and heart failure/heart transplantation 18.6%, 22.4%, and 46.6% (P=0.0005), respectively. Conclusions Among patients corrected with Mustard or Senning transposition of the great arteries, the most common CoD is SCD followed by heart failure/heart transplantation. The CoD changes as the patients age, with SCD as the most common cause in adolescence and heart failure as the dominant cause in adulthood. Furthermore, the risk of all‐cause mortality, SCD, and death attributable to heart failure or heart transplantation was increased in men >10 years after the Mustard/Senning operation.

Delays at court are an everlasting and potentially consequential reality of criminal justice systems, although most would agree that the timely adjudication of cases is needed from both administrative, judicial, and individual perspectives. This paper uses administrative data and a policy reform in Denmark in 2007 to measure the unconfounded association between court delays – or, more specifically, time to adjudication – and criminal recidivism within 5 years. Results show that although court delays do not push more people into recidivism, the delays matter for how many crimes recidivists end up being convicted of. Also, criminality tends to be muted during the period from charge to adjudication (even in a context with low use of pretrial detention and no bail system), whereby court delays also matter for the timing of new crimes – a finding with important theoretical implications.
