ReviewMortality and morbidity in patients with osteogenesis imperfecta in Denmark.
Ostegenesis imperfecta (OI) is a hereditary disease of the connective tissue caused by mutations to, mainly, the genes that are involved in the biosynthesis of collagen type 1. Patients are grouped according to clinical severity and mode of inheritance according to Sillence's classification (originally 1979, updated 2014). According to our data, the population prevalence of OI in Denmark was 10.3 per 100,000, with 575 patients registered with an OI diagnosis in the National Patient Register and alive at the end of 2012 out of a total population of 5,602,628 persons. ⋯ We corrected for this increased risk by using a competing risk regression model. We found that the OI population had increased relative risk of mitral valve regurgitation (sub hazard ratio (SHR) 6.3), aortic valve regurgitation (SHR 4.5), atrial fibrillation/flutters (SHR 1.7) and heart failure (SHR 2.3) compared to the reference population. There was no difference in the risk of arterial aneurisms or arterial dissections. Conclusion: Patients with OI have increased risk of valvulopathies, atrial arrhythmias and heart failure when compared to the reference population, even after adjusting for risk factors for these car-diovascular diseases - indicating that the quantitative or qualitative defects of collagen type 1 synthesis seen in OI influence the risk of these cardiovascular diseases in patients with OI.

ReviewSunscreen use at Danish beaches and how to improve coverage.
Exposure to ultraviolet radiation (UVR) from the sun is the main risk factor for development of skin cancer. The incidence of skin cancer in Denmark and worldwide is high and increasing. The overall aim was to achieve basic knowledge about sun protection with sunscreen among beachgoers in Denmark. ⋯ After a single application, either as at the beach or with the use of a handful of sunscreen, about one fifth of the total accessible skin was left without sunscreen. After double application only about a 9% of the accessible skin was left uncovered. As especially missed areas are at risk of getting sunburned double application seems to be the better of the two tested strategies to improve coverage.

Iron deficiency and anaemia in the puerperium are associated with several important clinical consequences, most prominently physical fatigue. Current treatment practice with oral iron supplementation is associated with gastrointestinal side-effects and subsequent poor compliance. Red blood cell transfusion is also widely used to treat severe postpartum anaemia, though accumulating evidence questions its risk-benefit ratio. ⋯ The difference in biochemical markers was larger than the patient-reported outcomes in the first week. A larger trial is needed to determine whether a high single-dose iron infusion is non-inferior to red blood cell transfusion in severe postpartum anaemia. The third study compared iron concentration in breast milk in a randomised sample of women receiving high single-dose iron infusion or oral iron. A high single-dose iron infusion lead to a transient increase in the iron concentration in breast milk, which remained within the normal range. In conclusion, iron isomaltoside seems to be associated with improved patient-reported outcomes compared to oral iron treatment, and in severe postpartum anaemia intravenous iron seems promising as an alternative to red blood cell transfusion.

ReviewDepression, stroke, and dementia in patients with myocardial infarction.
The connection between the heart and mind has been studied since Sir William Harvey observed more than 350 years ago that negative emotions adversely affect the heart. Today, we know that diseases of the mind can affect the heart and, conversely, that heart diseases can cause both physical and mental diseases of the brain. To explore this relation further, we examined how previous depression affects survival in patients with myocardial infarction (MI) (study II), and how the occurrence of MI affects the risk of ischemic and hemorrhagic stroke (study III) and dementia (study IV). ⋯ Compared with the general population cohort, MI patients were not at increased risk of all-cause dementia (adjusted hazard ratio = 1.01, 95% CI 0.98-1.03). In subgroups of dementia, we observed no substantial association with Alzheimer's disease (adjusted hazard ratio = 0.92, 95% CI 0.88-0.95) or other dementias (adjusted hazard ratio = 0.98, 95% CI 0.95-1.01). However, patients with MI had an increased risk of vascular dementia (adjusted hazard ratio = 1.35, 95% CI 1.28-1.43). In conclusion, we found that preceding depression was associated with moderately increased mortality after MI, and that was associated with an increased risk of stroke and vascular dementia, but not dementia from other causes.

ReviewPulmonary artery perfusion versus no pulmonary per-fusion during cardiopulmonary bypass.
During conventional cardiopulmonary bypass (CPB) there is no active perfusion of the pulmonary circulation and the mechanical ventilation is ceased leaving the lungs exposed to warm ischemia. Pulmonary dysfunction is seen in varying degrees after major surgery, but more severe in cardiac surgery patients probably due to the effects of CPB. The evidence for effect and safety are limited, but active pulmonary artery perfusion during CPB could be beneficial for the patients' postoperative oxygenation. Our aim was in a randomised clinical trial to assess primarily the effect of pulmonary artery perfusion during CPB on postoperative oxygenation in patients diagnosed with chronic obstructive pulmonary disease (COPD), secondarily to assess other possible benefits and harms. Furthermore, we wanted in a systematic review with meta-analyses of all randomised clinical trials to investigate the pooled effects of pulmonary artery perfusion during CPB. We planned and conducted a randomised, partly blinded, clinical trial assigning cardiac surgery patients diagnosed with COPD to receive pulmonary artery perfusion with oxygenated blood or histidine-tryptophan-ketoglutarate (HTK) solution compared to no pulmonary perfusion during CPB. ⋯ Pulmonary artery perfusion with HTK solution did not result in an improved oxygenation. In line with this, the systematic review including data from additional trials showed a possible association between pulmonary artery perfusion with blood and improved oxygenation, but no significant associations with mortality, serious adverse events or intubation time. However, all data are too sparse to be conclusive.
