To assess the safety of long-term treatment with flecainide in patients with atrial fibrillation (AF), particularly with regard to sudden cardiac death (SCD) and proarrhythmic events. ⋯ We found an increased incidence of SCD or proarrhythmic events in this real-world study of flecainide used for the treatment of AF. The findings suggest that further investigation into the safety of flecainide for the treatment of patients with AF is warranted.

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. ⋯ 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.

Epidemiological evidence suggests that infections may contribute to atherogenesis. However, with the exception of Chlamydophila pneumoniae, cultivable bacteria have not been recovered from atherosclerotic lesions. Therefore, we aimed at developing an approach to recover uncultivable bacteria from atherectomy tissues. ⋯ These results indicate that viable previously uncultivable bacterial species are present within atheromas. Our results suggest revisiting the hypothesis that infections may have a causative role in atherosclerotic inflammation and have implications for research regarding novel diagnostics and treatments for cardiovascular disease.

At present, a rapid and widely available diagnostic test for stroke remains elusive. The aim of this study was to examine the predictive value of a panel of blood-borne biochemical markers for stroke diagnosis. ⋯ A combination of biomarkers including caspase-3 and d-dimer appears to be the most promising to achieve a rapid biochemical diagnosis of stroke. If replicated, this approach could be used as a tool for urgent referral of stroke patients to hospitals in which acute treatments are available.

Colorectal cancer (CRC) is the third most common cause of cancer death worldwide and a major health problem. In this review, the different approaches for CRC screening will be outlined with emphasis on evidence-based medicine. Evidence from randomized trials on the effectiveness of CRC screening is summarized. ⋯ Although colonoscopy screening is used in some countries, no randomized trials have been conducted to estimate its benefit, and therefore, it should not be recommended at the present time. Faecal occult blood test and flexible sigmoidoscopy are the two CRC screening tools that can be recommended as they have been proven to reduce CRC mortality. Colonoscopy has the potential to be superior to FOBT and flexible sigmoidoscopy, but needs to be evaluated in randomized trials before any recommendation can be provided.
