RESUMEN
OBJECTIVE: To compare the incidence of type 1 diabetes (T1D) before and during the coronavirus disease 2019 (COVID-19) pandemic and determine whether severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is associated with T1D development. RESEARCH DESIGN AND METHODS: All Danish residents aged <30 years free of diabetes from 2015 to 2021 were included. Individuals were followed from 1 January 2015 or birth until the development of T1D, the age of 30, the end of the study (31 December 2021), emigration, development of type 2 diabetes, onset of any cancer, initiation of immunomodulating therapy, or development of any autoimmune disease. We compared the incidence rate ratio (IRR) of T1D using Poisson regression models. We matched each person with a SARS-CoV-2 infection with three control individuals and used a cause-specific Cox regression model to estimate the hazard ratio (HR). RESULTS: Among 2,381,348 individuals, 3,579 cases of T1D occurred. The adjusted IRRs for T1D in each quarter of 2020 and 2021 compared with 2015-2019 were as follows: January-March 2020, 1.03 (95% CI 0.86; 1.23); January-March 2021, 1.01 (0.84; 1.22), April-June 2020, 0.98 (0.80; 1.20); April-June 2021, 1.34 (1.12; 1.61); July-September 2020, 1.13 (0.94; 1.35); July-September 2021, 1.21 (1.01; 1.45); October-December 2020, 1.09 (0.91; 1.31); and October-December 2021, 1.18 (0.99; 1.41). We identified 338,670 individuals with a positive SARS-CoV-2 test result and matched them with 1,004,688 control individuals. A SARS-2-CoV infection was not significantly associated with the risk of T1D development (HR 0.90 [95% CI 0.60; 1.35]). CONCLUSIONS: There was an increase in T1D incidence during April-June 2021 compared with April-June 2015-2019, but this could not be attributed to SARS-CoV-2 infection.

OBJECTIVE: To study the association between behavioural factors and incidence rates of SARS-CoV-2 infection. DESIGN: Case-control web-based questionnaire study. SETTING: Questionnaire data were collected in the Capital Region of Denmark in December 2020 when limited restrictions were in place, while the number of daily SARS-CoV-2 cases increased rapidly. PARTICIPANTS: 8913 cases of laboratory-confirmed SARS-CoV-2 infection were compared with two groups of controls: (1) 34 063 individuals with a negative SARS-CoV-2 test from the same date (negative controls, NCs) and 2) 25 989 individuals who had never been tested for a SARS-CoV-2 infection (untested controls, UC). Controls were matched on sex, age, test date and municipality. EXPOSURE: Activities during the 14 days prior to being tested positive for SARS-CoV-2 or during the same period for matched controls and precautions taken during the entire pandemic. MAIN OUTCOMES AND MEASURES: SARS-CoV-2 infection incidence rate ratios (IRR). RESULTS: Response rate was 41.4% (n=93 121). Using public transportation, grocery shopping (IRR: NC: 0.52; UC: 0.63) and outdoor sports activities (NC: 0.75; UC: 0.96) were not associated with increased rate of SARS-CoV-2 infection. Most precautions, for example, using hand sanitizer (NC: 0.79; UC: 0.98), physical distancing (NC: 0.79; UC: 0.82) and avoiding handshakes (NC: 0.74; UC: 0.77), were associated with a lower rate of infection. Activities associated with many close contacts, especially indoors, increased rate of infection. Except for working from home, all types of occupation were linked to increased rate of infection. CONCLUSIONS: In a community setting with moderate restrictions, activities such as using public transportation and grocery shopping with the relevant precautions were not associated with an increased rate of SARS-CoV-2 infection. Exposures and activities where safety measures are difficult to maintain might be important risk factors for infection. These findings may help public health authorities tailor their strategies for limiting the spread of SARS-CoV-2.

INTRODUCTION: Knowledge of the seroprevalence and duration of antibodies against SARS-CoV-2 was needed in the early phases of the COVID-19 pandemic and is still necessary for policy makers and healthcare professionals. This information allows us to better understand the risk of reinfection in previously infected individuals. METHODS: We investigated the prevalence and duration of detectable antibodies against SARS-CoV-2 in sequentially collected samples from 379 healthcare professionals. RESULTS: SARS-CoV-2 seroprevalence at inclusion was 5.3% (95% confidence interval (CI): 3.3-8.0%) and 25% of seropositive participants reverted during follow-up. At the end of follow-up, the calculated probability of having detectable antibodies among former seropositive participants was 72.2% (95% CI: 54.2-96.2%). CONCLUSION: Antibodies against SARS-CoV-2 were detectable in a subset of infected individuals for a minimum of 39 weeks. FUNDING: The assays performed at Rigshospitalet were developed with financial support from the Carlsberg Foundation (CF20-0045) and the Novo Nordisk Foundation (NFF205A0063505 and NNF20SA0064201). TRIAL REGISTRATION: The study was registered with the Danish National Committee on Health Research Ethics (H-20022312).

INTRODUCTION: We aimed to evaluate post-COVID-19 fatigue, change in functional capacity and health-related quality of life (HRQoL) eight months after discharge from hospital due to COVID-19. METHODS: A total of 83 patients (35 women) admitted to the Copenhagen University Hospital - North Zealand Hospital, Denmark, for COVID-19 during the period from March to June 2020 were evaluated eight months after discharge using validated questionnaires quantifying fatigue, HRQoL and post-COVID-19 functional status. Follow-up data were correlated with measures of pre-COVID-19 status (anthropometrics, comorbidities) and measures of severity of the acute infection. RESULTS: A total of 22 (65%) women and 12 (26%) men reported excessive fatigue. In all, 20 women (67%) and 17 men (37%) reported decreased physical function. Female sex was associated with fatigue. Loss of physical function was associated with pre-COVID-19 presence of heart disease and absence of lung disease. Severity of the acute COVID-19 infection was not associated with fatigue or change in functional status. Fatigue and functional status were correlated with both generic HRQoL and lung disease-specific HRQoL. CONCLUSIONS: Female sex was associated with a higher risk of fatigue eight months after hospitalisation with COVID-19 infection. Regarding loss of functional capacity after COVID-19, we found an apparently protective effect of pre-COVID-19 lung disease. Our findings underscore the urgent need for further research and the importance of evaluating those recovering from COVID-19 for symptoms of excessive fatigue and change in functional capacity irrespective of the severity of the initial infection. FUNDING: none. TRIAL REGISTRATION: not relevant.

BACKGROUND: Addition of docetaxel to androgen deprivation therapy (ADT) for the treatment of metastatic hormone-sensitive prostate cancer (mHSPC) has been proved to be effective with an overall survival (OS) benefit in phase III clinical trials. The effectiveness of docetaxel with ADT in the general patient population remains unknown. OBJECTIVE: The purpose of this study is to report the clinical experience in mHSPC patients treated with 3rd-weekly docetaxel plus ADT in routine practice at two Danish institutions. DESIGN SETTING AND PARTICIPANTS: A two-center retrospective study including consecutive mHSPC patients treated with 3rd-weekly docetaxel plus ADT was conducted. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Outcomes of interest were OS, and biochemical and clinical progression-free survival. RESULTS AND LIMITATIONS: A total of 173 consecutive patients with mHSPC who received docetaxel every 3rd week plus ADT between June 2015 and February 2018 were included. Most patients had high-volume disease (85%). All six planned docetaxel cycles were delivered in 149 cases (86%). Of the patients, 106 (61%) were alive at the last follow-up. At a median follow-up of 42 (37.8-58.6) mo, the median OS was 51.6 (41.5-56.3) mo. Castration-resistant prostate cancer (CRPC) developed in 46% within 1 yr, with a median time to CRPC of 15.6 (13.0-18.1) mo. Prostate-specific antigen nadir ≤0.2 ng/l was achieved in 15% of patients after 6 mo of ADT and in 19% after 12 mo. CONCLUSIONS: The effect of docetaxel for mHSPC patients treated in routine practice appears comparable with the overall efficacy reported in the literature. Selection of patients will influence the results in clinical practice and clinical studies. PATIENT SUMMARY: In this report, we looked at the clinical effectiveness of docetaxel combined with androgen deprivation therapy in men with metastatic hormone-sensitive prostate cancer (mHSPC) in a Danish population. We found the effect of docetaxel treatment for mHSPC in the general population to be comparable with the overall efficacy reported in published studies.
RESUMEN
INTRODUCTION: Coronavirus disease 2019 (COVID-19) is an ongoing pandemic associated with significant morbidity and mortality worldwide. Limited data are available describing the clinical presentation and outcomes of hospitalised COVID-19 patients in Europe. METHODS: This was a single-centre retrospective chart review of all patients with COVID-19 admitted to the North Zealand Hospital in Denmark between 1 March and 4 May 2020. Main outcomes include major therapeutic interventions during hospitalisation, such as invasive mechanical ventilation, as well as death. RESULTS: A total of 115 patients were included, including four infants. The median age of adults was 68 years and 40% were female. At admission, 55 (50%) patients had a fever, 29 (26%) had a respiratory rate exceeding 24 breaths/minute, and 78 (70%) received supplemental oxygen. The prevalence of co-infection was 13%. Twenty patients (18%) (median age: 64 years; 15% female) were treated in the intensive care unit. Twelve (10.4%) received invasive mechanical ventilation and three (2.6%) renal replacement therapy. Nine patients (8%) developed pulmonary embolism. Sixteen patients (14%) died. Among patients requiring mechanical ventilation (n = 12), seven (6.1%) were discharged alive, four (3.4%) died and one (0.9%) was still hospitalised. CONCLUSION: In this cohort of hospitalised COVID-19 patients, mortality was lower than in other Danish and European case series. FUNDING: none. TRIAL REGISTRATION: not relevant.

OBJECTIVE: The aim of the present study was to emphasize the critical importance of the clinician's awareness of signet-ring cell carcinoma (SRCC) of the urinary bladder, a rare and aggressive disease entity. MATERIALS AND METHODS: A review of the current literature was conducted and a classic case of advanced SRCC of the urinary bladder is reported, clearly demonstrating the severity of this disease and the imperative need for standardized recommendations for the diagnostic work-up and management of urinary bladder SRCC. RESULTS: The prognosis for patients with SRCC of the urinary bladder is poor, attributed to presentation at advanced stages following asymptomatic progression, inefficacy of multimodality therapy and possibly an aggressive underlying biological phenotype. Treatment options are limited and not well studied. CONCLUSION: Given the rarity of SRCC, multi-institutional clinical trials and international cooperation are mandatory to improve survival for patients with primary SRCC of the bladder.
