Global and risk-group stratified well-being and mental health during the COVID-19 pandemic in adults: Results from the international COH-FIT Study.

International studies measuring wellbeing/multidimensional mental health before/ during the COVID-19 pandemic, including representative samples for >2 years, identifying risk groups and coping strategies are lacking. COH-FIT is an online, international, anonymous survey measuring changes in well-being (WHO-5) and a composite psychopathology P-score, and their associations with COVID-19 deaths/restrictions, 12 a-priori defined risk individual/cumulative factors, and coping strategies during COVID-19 pandemic (26/04/2020-26/06/2022) in 30 languages (representative, weighted non-representative, adults). T-test, χ2, penalized cubic splines, linear regression, correlation analyses were conducted. Analyzing 121,066/142,364 initiated surveys, WHO-5/P-score worsened intra-pandemic by 11.1±21.1/13.2±17.9 points (effect size d=0.50/0.60) (comparable results in representative/weighted non-probability samples). Persons with WHO-5 scores indicative of depression screening (<50, 13% to 32%) and major depression (<29, 3% to 12%) significantly increased. WHO-5 worsened from those with mental disorders, female sex, COVID-19-related loss, low-income country location, physical disorders, healthcare worker occupations, large city location, COVID-19 infection, unemployment, first-generation immigration, to age=18-29 with a cumulative effect. Similar findings emerged for P-score. Changes were significantly but minimally related to COVID-19 deaths, returning to near-pre-pandemic values after >2 years. The most subjectively effective coping strategies were exercise and walking, internet use, social contacts. Identified risk groups, coping strategies and outcome trajectories can inform global public health strategies.

Alcohol habits and alcohol-related health conditions of self-defined lifetime abstainers and never binge drinkers.

BACKGROUND: Prior research has shown that using lifetime abstainers as the reference group to examine the association between alcohol use and health-related consequences has several disadvantages. The aim of the present study was to examine the consistency of self-reported lifetime abstention and never-binge drinking, respectively, using national, longitudinal data collected in 2019 and 2020. Additionally, the prevalence of alcohol-related morbidity among lifetime abstainers was examined by linking survey data to alcohol-related morbidity data in a national patient register. METHODS: Data come from the Danish Health and Wellbeing Survey in 2019 and from a follow-up survey of the same individuals in 2020. A random sample of 14,000 individuals aged 15 years or older was drawn in mid-August 2019. Data were collected between September and December 2019. All those who were invited to the survey in 2019 and who were still alive and living in Denmark were invited to participate in a follow-up survey in 2020. Data in both waves were collected by self-administered questionnaires. Both questionnaires included the standard questions on alcohol consumption from the European Health Interview Survey model questionnaire. Information on alcohol-related morbidity was obtained from the Danish National Patient Register. RESULTS: In all, 5000 individuals completed the questionnaire in both waves. Approximately half (44.4%) of the individuals who declared that they were lifetime abstainers in 2020 (n = 252) had reported in 2019 to have drunk at some point in their life. Moreover, 39.7% contradicted earlier reported binge drinking. Furthermore, 2.4% of the respondents who defined themselves as lifetime abstainers in 2020 had earlier been diagnosed with an alcohol-related health condition. CONCLUSION: The present research reaffirms previous studies which have found self-reported lifetime abstainers to be unreliable as a consistent reference group. Additionally, the results indicated that a non-negligible proportion of lifetime abstainers had been diagnosed with an alcohol-related health condition.

Childhood poverty trajectories and trajectories of healthcare contacts in adolescence and young adulthood.

BACKGROUND: In this longitudinal study on Danes born 1980-2000, the objectives were to identify and describe trajectories of childhood poverty and explore their association with trajectories of contacts with the healthcare system. METHODS: Children born in Denmark from 1980-2000 were linked to national registers. Parental disposable income information was obtained for each year of the child's life from 0-16 years. Group-based trajectory modeling was used to identify trajectories of childhood poverty. The outcome was trajectories of contacts with the healthcare system identified with group-based multi-trajectory modeling. The associations between childhood poverty trajectories and trajectories of contacts with the healthcare system were estimated using multinomial logistic regression. RESULTS: Four distinct groups of childhood poverty trajectories were identified. The largest group (87 %) had very low probability of childhood poverty, and the smallest group (2 %) had high probability of persistent poverty throughout childhood. Two groups experienced either early (5 %) or late (6 %) poverty in childhood. Early and late childhood poverty were associated with higher odds of being in the psychiatric use group in both sexes, and with higher odds of being in the low use and high use groups in women. Persistent poverty was associated with higher odds of being in the low use group and lower odds of being in the high use group and the psychiatric use group in both sexes. CONCLUSION: In conclusion, childhood poverty is associated with healthcare contacts in adolescence and early adulthood in Denmark.

The Impact of Implementation Fidelity of a School-Based Multi-Component Smoking Prevention Intervention on Vocational Students' Smoking Behavior: A Cluster-Randomized Controlled Trial.

Preventing young people's cigarette smoking is a major public health priority, and smoking is especially prevalent in vocational schools. Well-enforced comprehensive school tobacco policies accompanied by preventive efforts show potential to reduce smoking, but the implementation process is crucial to achieve the intended effect. We investigate whether and how implementation fidelity of a multi-component smoking prevention intervention impacted student smoking outcomes after 4-5 months among students in Danish vocational education and training (national age range 15-65 years, mean 25.6) and preparatory basic education (national age range 15-25 years, mean 17.6) institutions using questionnaire data from a cluster-RCT. The intervention included a smoke-free school hours policy, educational curriculum, and class competition. We calculated an overall implementation fidelity measure combining staff-reported school-level delivery (fidelity) and student-reported receipt (participation, responsiveness), and used multilevel regression models to analyze associations with smoking outcomes (smoking daily, regularly, and during school hours). We supplemented the analysis with restricted cubic spline regression. Additionally, we stratified the analyses by school types and analyzed associations between implementation fidelity of the separate intervention components and smoking outcomes. High implementation was associated with lower odds of regular smoking (OR: 0.37, 95% CI: 0.18-0.78) and smoking during school hours, but not daily smoking, and these associations varied between the school settings. When analyzed separately, implementation fidelity of the components did not affect the outcomes significantly. Our findings underline the need to support the implementation process of school tobacco policy interventions to ensure the intended effects of reducing students' smoking.

Potentially avoidable mortality among adults with intellectual disability.

Persons with intellectual disabilities (ID) face pronounced health disparities. The aim of this study was to describe premature mortality by causes of death and avoidable mortality among persons with ID compared to the general Danish population. This study is based on a Danish nationwide cohort of adults (aged 18-74 years) with ID (n = 57 663) and an age- and sex-matched reference cohort (n = 607 097) which was established by linkage between several registers. The cohorts were followed in the Register of Causes of Death between 2000 and 2020. Causes of death were categorized into preventable, treatable, or unavoidable deaths using the OECD/Eurostat classification and furthermore categorized into specific interventions. We compared the observed and expected number of deaths by calculating standardized mortality ratio (SMR). Among persons with ID the number of deaths was 9400 whereof 5437 (58%) were avoidable. SMR for preventable deaths, e.g. by reducing smoking and alcohol intake or by vaccination, was 2.62 (95% CI, 2.51-2.73), and SMR for treatable deaths, e.g. by earlier diagnosis and treatment, was 6.00 (5.72-6.29). Unavoidable mortality was also six-fold increased (SMR = 6.03; 5.84-6.22). Preventable deaths were higher for persons with mild ID compared to severe ID, while treatable and unavoidable mortality were highest for persons with severe ID. The study confirmed that persons with ID have an amplified risk of mortality across all categories. There is a need for competence development of social care and healthcare personnel and reasonable adjustment of health promotion programs and healthcare services for people with ID.

An occupational health literacy intervention in nursing homes improved organizational health literacy - a quasi-experimental stepped wedge cluster trial.

OBJECTIVE: This study examined the effectiveness of a workplace health literacy intervention on individual, interpersonal, and organizational health literacy. METHOD: Using a quasi-experimental stepped wedge cluster design, we evaluated an intervention for 509 nursing home employees with two elements: 1) Courses for employees and management on pain prevention, management, and communication; 2) Structured dialogues between employees and supervisors, emphasizing pain prevention. RESULTS: One organizational health literacy item improved, with supervisors helping with pain prevention increasing by 0.42 points (95% CI 0.11;0.73). Positive trends were observed in supervisor actions when informed about pain (0.39 points, 95% CI -0.09;0.86), ease of finding workplace pain solutions (0.12 points, 95% CI -0.03;0.79), and employees having pain management information (0.44 points, 95% CI -0.03;0.92). CONCLUSION: The intervention improved one organizational health literacy item, with positive trends in three other items.

Evaluating neurocognitive outcomes in out-of-hospital cardiac arrest survivors: A comparative study of performance-based and reported measures.

AIMS: To (1) describe the prevalence of cognitive dysfunctions using performance-based and reported measures, and (2) explore the correlations between selected performance-based, patient-reported, and observer-reported neurocognitive outcome measures three months after hospital discharge in a population of out-of-hospital cardiac arrest (OHCA) survivors. METHODS: Data from 193 OHCA survivors was derived from the Danish multicenter REVIVAL cohort study. At three months, four subtests of the performance-based Delis-Kaplan Executive Function System (D-KEFS) (Trail making, Color-word interference, Verbal fluency, and Figure design), the patient-reported Behavior Rating Inventory of Executive Function - Adult (BRIEF-A), and the observer-reported 16-item Short Form (SF) Informant Questionnaire on Cognitive Decline after Cardiac Arrest (SF-16 IQCODE-CA) were collected. Spearman's rank coefficient correlation analysis was performed to examine correlations between D-KEFS, BRIEF-A, and SF-16 IQCODE-CA. RESULTS: Overall, 21% of survivors exhibited impairment in executive functioning using the D-KEFS subtest Color-word interference, while only 9% self-reported executive impairment (BRIEF-A) and 7% of relatives reported cognitive decline (SF-16 IQCODE-CA) in survivors at three months post-arrest. All correlations between D-KEFS, BRIEF-A and SF-16 IQCODE-CA were negligible to low. CONCLUSION: The results of this REVIVAL substudy suggest that although the performance-based and reported measures did not correlate, dual neurocognitive screening tools containing both a self-reported and an informant-reported version may have the potential to detect executive discrepancies in the return to everyday life and guide targeted neurorehabilitation after OHCA.

Socioeconomic equality in initiation of biologic treatment in Danish patients with inflammatory bowel disease.

BACKGROUND: Low socioeconomic status is associated with disadvantages in health outcomes and delivery of medical care in patients with Inflammatory Bowel Disease (IBD). Inequality in the utilisation of biologic treatment is largely unexplored. AIM: To explore the potential association of socioeconomic status and time to first biologic treatment in a population-based IBD cohort. METHODS: All 37,380 IBD incidences between 2000 and 2017 from the Danish National Patient Register were identified and linked to socioeconomic information including educational level, income and occupational status at diagnosis. Hazard ratios for receiving biologic treatment among socioeconomic groups were estimated using Cox proportional hazard regression. RESULTS: No difference in time between diagnosis and biologic treatment initiation was found comparing patients with upper secondary, vocational, or academic education to those with lower secondary education in patients with IBD. Patients with Crohn's disease in the two highest income quartiles received biologic treatment earlier (HR 1.16; 95% CI: 1.04; 1.30 & HR 1.15; 95% CI: 1.03; 1.30). An elevated treatment rate was found for persons with "other" occupational status (unspecified source of income) compared to employed persons in patients with ulcerative colitis (HR 1.36; 95% CI: 1.11; 1.66), but not in patients with Crohn's disease. CONCLUSION: This study revealed equal initiation of biologic treatment among patients with IBD across different educational background, income and occupational status. However, results are limited to a setting with free universal healthcare coverage and treatment needs should be considered and addressed in future research.

A systematic review and meta-analysis of the child-level effects of family-based interventions for the prevention of type 2 diabetes mellitus.

AIMS: The purpose of this systematic review and meta-analysis was to investigate the effects of family-based health promotion interventions on child-level risk factors for type 2 diabetes in vulnerable families. METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist for systematic reviews formed the methodological framework. CINAHL, Embase, MEDLINE, PsycINFO, and Web of Science were searched on January 12, 2024. The NTP-OHAT Risk of Bias Assessment Tool was used to assess the risk of bias in the individual studies, and meta-analyses were performed. RESULTS: The 4723 studies were identified, and 55 studies met the inclusion criteria. Results showed significant effects on children's body mass index (mean difference [MD], -0.18, 95% CI [-0.33 to -0.03], p = 0.02), body fat percentage (MD, -2.00, 95% CI [-3.31 to -0.69], p = 0.003), daily activity (standardized mean difference [SMD], 0.23, 95% CI [0.01; 0.44], p = 0.04), physical activity self-efficacy (SMD, 0.73, 95% CI [0.36 to 1.10], p < 0.01), intake of snacks (MD, -0.10, 95% CI [-0.17 to -0.04], p = 0.002), and sugar-sweetened beverages (SMD, -0.21, 95% CI [-0.42 to -0.01], p = 0.04). Subgroup analyses suggested that interventions aiming to change child and parent behavior simultaneously have larger effect on fasting glucose and nutrition consumption, and that interventions longer than 26 weeks have larger effects on body composition and physical activity behavior than shorter interventions.

Validation of the de Morton mobility index (DEMMI) among acute stroke patients aged ≥65 years: a register study.

PURPOSE: To validate the de Morton Mobility Index (DEMMI) in older (≥65 years) patients with acute stroke in a hospital setting within the first week after stroke onset. MATERIALS AND METHODS: In the Danish National Database of Geriatrics, we identified 4,176 patients with acute stroke (≥65 years). Floor and ceiling effects of DEMMI were investigated. Furthermore, convergent validity was investigated by correlations between DEMMI and the Barthel Index using Spearman's rho. Known-groups validity was tested by comparing DEMMI scores for different groups (with/without dementia, depression, comorbidity, and walking aids), and unidimensionality of DEMMI was evaluated by Mokken scale analysis. RESULTS: A floor effect was identified with 22.1% of the patients scoring 0 on DEMMI on admission. Both convergent and known-groups validity were confirmed for DEMMI. Patients who were bedbound had a lower DEMMI score (median [IQR]: 0 [0;0]) than patients without any walking aid (median [IQR]: 62 [33;74]). Furthermore, Mokken scale analysis identified unidimensionality with overall fit to the model (Loevinger H 0.88 (p < 0.0001)). CONCLUSION: DEMMI is a valid instrument for use in patients with acute stroke (≥65 years) in a hospital setting within the first week after stroke onset.

The de Morton Mobility Index (DEMMI) is a unidimensional measurement instrument of mobility in older (≥65 years) individuals with acute stroke and can be used in acute clinical work to help assess mobility ability and in planning of rehabilitation for the patient groupThe DEMMI has a high convergent validity, with a high correlation with the Barthel Index.The DEMMI has known-groups validity, as DEMMI is significantly different in patients with depression and dementia compared with patients without these conditions, and different in patients using a walking aid on admission compared with non-users and in patients with co-morbidity compared with non-comorbid patients.

Loneliness and the risk of type 2 diabetes.

INTRODUCTION: The incidence of type 2 diabetes is increasing globally. Recent research suggests that loneliness could be a potential risk factor for the development of type 2 diabetes. We aimed to investigate the association between loneliness and type 2 diabetes and the modifying effect of mental disorders. RESEARCH DESIGN AND METHODS: We conducted a prospective study including 465 290 adults (aged ≥16 years) who participated in either the Danish Health and Morbidity Survey or the Danish National Health Survey between 2000 and 2017. Loneliness was based on self-report, while type 2 diabetes was measured using an algorithm combining several health registers including type 2 diabetes patients treated both within the hospital sector and general practice. Cox proportional hazards regressions were used to estimate hazard ratios (HRs) and 95% confidence intervals (95% CIs). RESULTS: During a mean follow-up time of 6.3 years, 13 771 individuals (3%) developed type 2 diabetes. Feeling lonely once in a while was associated with a 14% increased risk of type 2 diabetes (95% CI 1.09 to 1.20), while feeling lonely often was associated with a 24% increased risk (95% CI 1.14 to 1.34), independent of sociodemographic factors and body mass index. The association was stronger among individuals without a mental disorder (HR 1.21, 95% CI 1.10 to 1.34 among those feeling lonely often) compared with those with a mental disorder (HR 1.07, 95% CI 0.93 to 1.23). CONCLUSIONS: Loneliness independently increased the risk of type 2 diabetes. The effect was more pronounced in individuals without a mental disorder, as having a mental disorder itself likely increases the risk of type 2 diabetes. These findings emphasize the importance of addressing loneliness as a modifiable risk factor in preventing type 2 diabetes.

Sleep disorders and sleep disturbances in persons with multiple sclerosis: A population-based matched case-control study in Denmark.

Introduction Adverse sleep is common in multiple sclerosis (MS). Population-based studies including adequate control groups are lacking. We hypothesized that the prevalence of sleep disorders and other sleep disturbances would be higher in persons with MS than in controls. Methods We conducted a population-based study linking individual-level data from the Danish MS Registry (n=21,943 persons with MS) and the Danish Population Registry (n=109,715 matched controls) with information on sleep disorders from the Danish National Patient Registry and other sleep disturbances assessed by dispensed prescription drugs from the Danish National Prescription Registry. Results Prevalence of diagnosed sleep disorders in terms of central hypersomnia (0.15% vs. 0.06%), sleep disturbances (1.05% vs. 0.70%), and sleep movements (0.22% vs. 0.13%) and other sleep disturbances identified by dispensed central acting (10.73% vs. 1.10%) and hypnotic use (30.65% vs. 20.13%) medication was statistically significantly higher among persons with MS when compared to controls. We found no statistically significant difference in the prevalence of sleep apnea and parasomnia between groups. Stratified by sex and age at MS diagnosis, results for differences between persons with MS and controls were similar. Conclusion In this registry-based study, we found that the prevalence of several diagnosed sleep disorders was higher persons with MS than in controls, that is those reflecting insomnia and daytime symptoms including hypersomnia. Other sleep disturbances identified by dispensed prescription medication was markedly higher in persons with MS than controls.

Association between digital health literacy and physical activity levels among individuals with and without long-term health conditions: Data from a cross-sectional survey of 19,231 individuals.

Objectives: This study explored associations between digital health literacy and physical activity levels and assessed potential interactions of long-term health conditions. Methods: A cross-sectional survey was sent to 34,000 inhabitants in Region Zealand, Denmark. The survey included items on physical activity levels and three electronic Health Literacy Questionnaire (eHLQ) scales (1, 4, and 5). Associations were assessed by logistic regression and adjusted for confounders. Results: A total of 19,231 participated in the survey. Positive associations were found between higher digital health literacy and being active >30 min./week at moderate-to-vigorous intensity (eHLQ 1: OR 1.24, p < 0.001; eHLQ 4: OR 1.13, p = 0.012; eHLQ 5: OR 1.25, p < 0.001), compliance with the World Health Organization minimum recommendations for physical activity (eHLQ 1: OR 1.33 p < 0.001; eHLQ 4: OR 1.08 p = 0.025; eHLQ 5: OR 1.32, p < 0.001), and self-reported physical active (eHLQ 1: OR 1.50 p < 0.001; eHLQ 4: OR 1.24 p < 0.001; eHLQ 5: OR 1.54 p < 0.001), even when fully adjusted for covariates. No significant interaction was found for long-term health conditions. However, individuals with more long-term health conditions exhibited the lowest digital health literacy scores (9% to 19% scored <2.0). Conclusion: A higher digital health literacy is positively associated with higher physical activity levels. This highlights the importance of screening and promoting digital health literacy in managing digital health and digital physical activity interventions. Future research should explore strategies and targeted interventions to enhance digital health literacy and improve health outcomes.

Risk of cardiovascular disease in patients with multiple sclerosis treated with fingolimod compared to natalizumab: A nationwide cohort study of 2095 patients in Denmark.

BACKGROUND: Fingolimod may be associated with risk of developing cardiovascular disease (CVD). Studies including reference groups and long follow-up are scarce. OBJECTIVES: We hypothesized that patients treated with fingolimod would be at higher risk of developing CVD compared to patients treated with natalizumab. METHODS: A nationwide 12-year cohort study linking individual-level data from the Danish Multiple Sclerosis Registry with health registries on 2095 adult patients with multiple sclerosis (MS) without any health records of CVD at follow-up start. Exposure to fingolimod and natalizumab was defined by the first treatment of at least 3 months. Cohort entry was from 2011 to 2018. We defined CVD as a composite measure, including hypertension, ischemic heart disease, atrial fibrillation, heart failure, and stroke. We used multivariable adjusted Cox regression. RESULTS: There were 28.8 and 17.4 CVD events per 1000 person-years in fingolimod and natalizumab groups, respectively. Compared to natalizumab-treated patients, fingolimod-treated patients had a higher risk of CVD (hazard ratio (HR) = 1.57; 95% confidence interval (CI) = 1.18-2.08). Hypertension comprised 200 of 244 CVD events. CONCLUSION: We found an increased risk of CVD in patients with MS treated with fingolimod. This increased risk was mainly due to hypertension.

Educational outcomes and the role of comorbidity among adolescents with type 1-diabetes in Denmark.

AIMS: To examine educational outcomes among adolescents with type 1 diabetes and determine the role of comorbidity. METHODS: We conducted a nationwide register-based cohort study including 3370 individuals born between 1991 and 2003 and diagnosed with type 1 diabetes before the age of 16. They were all matched with up to four individuals without type 1 diabetes on age, gender, parents' educational level and immigration status. Information on comorbidity was based on hospital diagnoses. The individuals were followed in registers to determine whether they finished compulsory school (9th grade, usually at the age of 15-16 years), and were enrolled in secondary education by age 18 years. RESULTS: Individuals with type 1 diabetes were more likely not to complete compulsory school (OR 1.44, 95% CI 1.26-1.64), and not being enrolled in an upper secondary education by age 18 (OR 1.50, 95% CI 1.31-1.73) compared to their peers. A total of 1869 (56%) individuals with type 1 diabetes were registered with at least one somatic (n = 1709) or psychiatric comorbidity (n = 389). Those with type 1 diabetes and psychiatric comorbidity were more likely not to complete compulsory school (OR 2.47, 95% CI 1.54-3.96), and not being enrolled in an upper secondary education by age 18 (OR 3.66, 95% CI 2.27-5.91) compared to those with type 1 diabetes only. Further, there was a tendency towards an association between having somatic comorbidity and adverse educational outcomes (OR 1.25, 95% CI 0.97-1.63; OR 1.26, 95% CI 0.95-1.66) among adolescents with type 1 diabetes. The associations differed markedly between diagnostic comorbidity groups. CONCLUSION: Type 1 diabetes affects educational attainment and participation among adolescents. Psychiatric comorbidity contributes to adverse educational outcomes in this group, and there is a tendency that somatic comorbidity also plays a role.

Using instrumental variables to correct for bias in real-world cohort studies of the effects of disease-modifying treatment in MS.

BACKGROUND: Estimating the effect of disease-modifying treatment of MS in observational studies is impaired by bias from unmeasured confounders, in particular indication bias. OBJECTIVE: To show how instrumental variables (IVs) reduce bias. METHODS: All patients with relapsing onset of MS 1996-2010, identified by the nationwide Danish Multiple Sclerosis Registry, were followed from onset. Exposure was treatment index throughout the first 12 years from onset, defined as a cumulative function of months without and with medium- or high-efficacy treatment, and outcomes were hazard ratios (HRs) per unit treatment index for sustained Expanded Disability Scale Score (EDSS) 4 and 6 adjusted for age at onset and sex, without and with an IV. We used the onset cohort (1996-2000; 2001-2005; 2006-2010) as an IV because treatment index increased across the cohorts. RESULTS: We included 6014 patients. With conventional Cox regression, HRs for EDSS 4 and 6 were 1.15 [95% CI: 1.13-1.18] and 1.17 [1.13-1.20] per unit treatment index. Only with IVs, we confirmed a beneficial effect of treatment with HRs of 0.86 [0.81-0.91] and 0.82 [0.74-0.90]. CONCLUSION: The use of IVs eliminates indication bias and confirms that treatment is effective in delaying disability. IVs could, under some circumstances, be an alternative to marginal structural models.

Diabetic complications and risk of depression and anxiety among adults with type 2 diabetes.

AIMS: To investigate if diabetic complications increase the risk of depression and/or anxiety among adults with type 2 diabetes. METHODS: This register-based, prospective study included 265,799 adult individuals diagnosed with type 2 diabetes between 1997 and 2017 without a recent history of depression or anxiety. Diabetic complications included cardiovascular disease, amputation of lower extremities, neuropathy, nephropathy and retinopathy. Both diabetic complications and depression and anxiety were defined by hospital contacts and prescription-based medication. All individuals were followed from the date of type 2 diabetes diagnosis until the date of incident depression or anxiety, emigration, death or 31 December 2018, whichever occurred first. RESULTS: The total risk time was 1,915,390 person-years. The incidence rate of depression and/or anxiety was 3368 per 100,000 person-years among individuals with diabetic complications and 1929 per 100,000 person-years among those without. Having or developing any diabetic complication was associated with an increased risk of depression and/or anxiety (HR 1.77, 95% CI 1.73-1.80). The risk for depression and/or anxiety was increased for all types of diabetic complications. The strongest association was found for amputation of lower extremities (HR 2.16, 95% CI 2.01-2.31) and the weakest for retinopathy (HR 1.13, 95% CI 1.09-1.17). CONCLUSION: Individuals with type 2 diabetes and diabetic complications are at increased risk of depression and anxiety. This points towards the importance of an increased clinical focus on mental well-being among individuals with type 2 diabetes and complications.

The Impact of Vaccination against SARS-CoV-2 on Health Outcomes and Hospital Visits after Omicron Infection in Children and Adolescents Aged 5-18 Years: A Danish Nation-Wide Cohort Study.

This study investigates the impact of vaccination against SARS-CoV-2 on health outcomes and hospital contacts in children and adolescents aged 5-18 years infected with the SARS-CoV-2 Omicron variant, comparing previously vaccinated with unvaccinated. Using national register data, vaccinated and unvaccinated Danish children and adolescents with a positive SARS-CoV-2 test between 1 January and 31 March 2022 (Omicron dominance period) were included. The Prior Event Rate Ratio (PERR) was used to explore differences in hospital contacts (hospitalizations and emergency room (ER) visits), while Inverse Treatment Probability Weighted (IPW) risk ratios were used to explore the risk of severe health outcomes within six weeks following SARS-CoV-2 infection. Vaccinated 5-11-year-old girls had fewer visits to the ER compared to unvaccinated ones, PERR 0.92 (95% CI 0.84-1.00). Vaccinated 5-11-year-old boys had fewer hospitalizations (PERR 0.79 (0.64-0.99)) and more ER visits (PERR 1.13 (1.04-1.22)) compared to unvaccinated ones. An unadjusted and significant lower risk of febrile seizure among vaccinated 5-11-year-olds compared to unvaccinated ones was found (risk ratio 0.12 (0.04-0.39), p ≤ 0.01. No significant differences were found for severe conditions or for croup or pneumonia in either age group. The results indicate a modest protective effect of the vaccine in terms of hospital contacts, but no protective effect on health outcomes after SARS-CoV-2 Omicron infection in this population of Danish children and adolescents.

Prediction of disease recurrence or residual disease after primary endoscopic resection of pT1 colorectal cancer-results from a large nationwide Danish study.

PURPOSE: Risk assessment of disease recurrence in pT1 colorectal cancer is crucial in order to select the appropriate treatment strategy. The study aimed to develop a prediction model, based on histopathological data, for the probability of disease recurrence and residual disease in patients with pT1 colorectal cancer. METHODS: The model dataset consisted of 558 patients with pT1 CRC who had undergone endoscopic resection only (n = 339) or endoscopic resection followed by subsequent bowel resection (n = 219). Tissue blocks and slides were retrieved from Pathology Departments from all regions in Denmark. All original slides were evaluated by one experienced gastrointestinal pathologist (TPK). New sections were cut and stained for haematoxylin and eosin (HE) and immunohistochemical markers. Missing values were multiple imputed. A logistic regression model with backward elimination was used to construct the prediction model. RESULTS: The final prediction model for disease recurrence demonstrated good performance with AUC of 0.75 [95% CI 0.72-0.78], HL chi-squared test of 0.59 and scaled Brier score of 10%. The final prediction model for residual disease demonstrated medium performance with an AUC of 0.68 [0.63-0.72]. CONCLUSION: We developed a prediction model for the probability of disease recurrence in pT1 CRC with good performance and calibration based on histopathological data. Together with lymphatic and venous invasion, an involved resection margin (0 mm) as opposed to a margin of ≤ 1 mm was an independent risk factor for both disease recurrence and residual disease.
