Grass-clover and biogas fertilizers as a climate efficient nutrient supply.

There is a need to take care of the nutrients in the system. Anaerobic digestion is a valuable way to convert the nutrients and produce renewable energy. A model is presented that use grass-clover as feedstock for anaerobic digestion and separate the digestate in 3 fractions. Anaerobic digestion and separation have positive effect on N2O-emissions. But a very dilute solution of ammonia and sulfur generated high emissions when applied to the soil with 100 kg N per hectare

Grass-clover and biogas fertilizers as a climate efficient nutrient supply

• Clover grass as a co-substrate in biogas production is an important source of biogenic nitrogen contributing to carbon sequestration and biodiversity • Anaerobic digestion has a high potential for reduction of GHG emissions • High nitrogen efficiency of ammonia-rich fractions • Dried fiber fraction immobilizes nitrogen but is usable as phosphorus source for legume crop

The Nordic Arthroplasty Register Association: A unique collaboration between 3 national hip arthroplasty registries with 280,201 THRs

Background and purpose The possibility of comparing results and of pooling the data has been limited for the Nordic arthroplasty registries, because of different registration systems and questionnaires. We have established a common Nordic database, in order to compare demographics and the results of total hip replacement surgery between countries. In addition, we plan to study results in patient groups in which the numbers are too small to be studied in the individual countries

Pharmacological Undertreatment of Coronary Risk Factors in Patients with Psoriasis: Observational Study of the Danish Nationwide Registries

BACKGROUND: Patients with psoriasis have increased prevalence of coronary risk factors and limited recent results have suggested that these risk factors are undertreated in patients with psoriasis. This may contribute to the increased risk of cardiovascular diseases observed in patients with psoriasis. OBJECTIVE: To examine the pharmacological treatment of coronary risk factors in patients with severe psoriasis treated with biologic agents in a real-world setting. METHODS AND FINDINGS: Medical history of patients with severe psoriasis treated with biologic agents in the time period 2007-09 was retrieved from a Danish nationwide registry (DERMBIO). Individual-level linkage of nationwide administrative registries of hospitalizations, concomitant medications, and socioeconomic status was performed to gain insights into the use of pharmacological treatment. A total of 693 patients (mean age 46.1 ± 12.7 years, 65.7% male) with severe psoriasis treated with biologic agents were identified. Hypertension, hypercholesterolemia, and diabetes mellitus were identified in 16.6%, 9.2%, and 6.7% of cases, respectively. Patients with severe psoriasis were significantly less likely to receive cardiovascular pharmacotherapy compared to age, sex, and coronary risk factor matched controls. In psoriatic patients with hypertension 27.7% received no antihypertensive pharmacotherapy. Patients with dyslipidemia received cholesterol-lowering medications in 55.8% of cases and patients with diabetes mellitus received angiotensin converting enzyme inhibitors/angiotensin II receptor blockers and cholesterol-lowering medications in 42.1% and 23.7% of cases, respectively. Similar results were found for the subset of patients with >1 coronary risk factor and for high risk patients with established atherosclerotic disease. CONCLUSION: This nationwide study of patients with severe psoriasis demonstrated substantial undertreatment of coronary risk factors. Increased focus on identifying cardiovascular risk factors and initiation of preventive cardiovascular pharmacotherapy in patients with psoriasis is warranted
