Objectives. The magnitude of cardiovascular risk associated with psoriasis has been debated and the prognostic impact of psoriasis following myocardial infarction (MI) is unknown. Therefore, we investigated the risk of mortality and adverse cardiovascular events in patients with psoriasis following first-time MI.Design, setting and participants. Cohort study of the entire Danish population including all individuals who experienced first-time MI during the period [2002][2003][2004][2005][2006]. Multivariable Cox regression models were used to assess the post-MI prognostic impact of psoriasis.Main outcome measures. All-cause mortality and a composite cardiovascular end-point of recurrent MI, stroke and cardiovascular death.Results. A total of 462 patients with psoriasis and 48 935 controls (mean age 69.5 and 70.6 years, respectively) were identified with first-time MI during the study period. The mean follow-up was 19.5 months [standard deviation (SD) 16.5] for patients with psoriasis and 22 .0 months (SD 18.7) for those without psoriasis. Incidence rates (IRs) per 1000 patient-years for all-cause mortality were 119.4 [95% confidence interval (CI) 117.2-138.3] and 138.3 (95% CI 114.1-167.7) for patients without and with psoriasis, respectively, and the adjusted hazard ratio (HR) associated with psoriasis was 1.18 (95% CI 0.97-1.43). For the composite end-point, the IRs were 149.7 (95% CI 147.1-152.4) and 185.6 (95% CI 155.8-221.0) for patients without and with psoriasis, respectively, with an HR of 1.26 (95% CI 1.04-1.54) for patients with psoriasis.Conclusion. This first study of the impact of psoriasis on prognosis after first-time MI indicated a significantly impaired prognosis in patients with psoriasis. Further studies of this novel association are warranted.

Objectives This study aimed to explore return to work after COVID-19 and how disease severity affects this. Study design This is a Nationwide Danish registry–based cohort study using a retrospective follow-up design. Methods Patients with a first-time positive SARS-CoV-2 polymerase chain reaction test between 1 January 2020 and 30 May 2020, including 18–64 years old, 30-day survivors, and available to the workforce at the time of the first positive test were included. Admission types (i.e. no admission, admission to non–intensive care unit [ICU] department and admission to ICU) and return to work was investigated using Cox regression standardised to the age, sex, comorbidity and education-level distribution of all included subjects with estimates at 3 months from positive test displayed. Results Among the 7466 patients included in the study, 81.9% (6119/7466) and 98.4% (7344/7466) returned to work within 4 weeks and 6 months, respectively, with 1.5% (109/7466) not returning. Of the patients admitted, 72.1% (627/870) and 92.6% (805/870) returned 1 month and 6 months after admission to the hospital, with 6.6% (58/870) not returning within 6 months. Of patients admitted to the ICU, 36% (9/25) did not return within 6 months. Patients with an admission had a lower chance of return to work 3 months from positive test (relative risk [RR] 0.95, 95% confidence interval [CI] 0.94–0.96), with the lowest chance in patients admitted to an ICU department (RR 0.54, 95% CI 0.35–0.72). Female sex, older age, and comorbidity were associated with a lower chance of returning to work. Conclusion Hospitalised patients with COVID-19 infection have a lower chance of returning to work with potential implications for postinfection follow-up and rehabilitation.

Our results suggest that diabetic osteopenia does not have any clinical impact on fracture risk.
