Degos' disease, known confusingly as malignant strophic papularis, is an uncommon condition of unknown cause characterized by distinctive infarctive lesions in the skin, gastrointestinal tract, and central nervous system; the lesions at the two latter sites often result in death. We deem Degos' disease to be analogous to lupus erythematosus in the sense that each is fundamentally a systemic pathologic process involving several organs, among them the skin, but, moreover, we regard Degos' disease, in most instances, to be an actual manifestation of lupus erythematosus. Histopathologically, the findings in sections of tissue of skin lesions of Degos' disease are indistinguishable from those of one expression of cutaneous lupus erythematosus; immunopathologically, some patients with morphologic findings stereotypical of Degos' disease display signs characteristic of lupus erythematosus. For these reasons, we consider Degos' disease to be a distinctive pattern of disease, rather than a specific disease per se, just as are erythema multiforme, erythema nodosum, leukocytoclastic vasculitis, Sweet's syndrome, and pyoderma gangrenosum, to name but five of scores of them. The singular pattern that is designated Degos' disease usually is an expression of lupus erythematosus, but, episodically, of conditions like dermatomyositis and rheumatoid arthritis.

Rosiglitazone therapy improves insulin sensitivity and glucose uptake in patients with uncomplicated type 2 diabetes. In coronary artery disease (CAD), glucose is an important source of energy and preserved myocardial glucose uptake is essential for the viability of jeopardized myocardium. The aim was to test whether rosiglitazone changes myocardial metabolism in type 2 diabetic patients with CAD. We studied 54 patients (38 men and 16 women) with type 2 diabetes (HbA 1c 7.2 ؉ 0.9%) and CAD. Myocardial glucose uptake was measured with [18 F]fluoro-2-deoxy-D-glucose positron emission tomography in ischemic (evaluated by single-photon emission tomography and coronary angiography) and nonischemic regions during euglycemic-hyperinsulinemic clamp before and after a 16-week intervention period with rosiglitazone (n ‫؍‬ 27) or placebo (n ‫؍‬ 27). Rosiglitazone significantly improved glycemic control (P < 0.0001) and whole-body insulin sensitivity (P < 0.0001). Rosiglitazone increased myocardial glucose uptake from 20.6 ؎ 11.8 to 25.5 ؎ 12.4 mol ⅐ 100 g ؊1 ⅐ min ؊1 (P ‫؍‬ 0.038 vs. baseline, P ‫؍‬ 0.023 vs. placebo) in ischemic regions and from 21.7 ؎ 12.1 to 28.0 ؎ 12.7 mol ⅐ 100 g ؊1 ⅐ min ؊1 (P ‫؍‬ 0.014 vs. baseline, P ‫؍‬ 0.003 vs. placebo) in nonischemic regions. The increase in myocardial glucose uptake was partly explained by the suppression of free fatty acid levels during clamp. Rosiglitazone therapy significantly increased insulin sensitivity and improved myocardial glucose uptake in type 2 diabetic patients with CAD. These results suggest that rosiglitazone therapy may facilitate myocardial glucose storage and utilization in these patients. Diabetes 54: 2787-2794, 2005

Since phosphorus (P) is an essential element for life, its usage and application across agricultural production systems requires great attention. Monogastric species such as pigs and poultry can significantly contribute to global food security but these animals remain highly dependent on the supply of mineral inorganic P in their feeds. Pig and poultry, which represent 70% of the global meat production, are also major P excretors and thus represent important sources of environmental P inputs. Balancing the P cycle within farming systems is crucial to achieve P sustainable and resilient livestock production. Therefore, the interconnection of animal feed, livestock farming, manure, and soil/aquatic ecosystems requires multidisciplinary approaches to improve P management. With regard to a sustainable agricultural P cycle, this study addresses aspects of feeding strategies and animal physiology (e.g., phase feeding, P conditioning, liquid feeding, phytase supplementation, genetics), soil agroecosystems (e.g., P cycling, P losses, P gains), reuse and recycling (e.g., manure, slaughter waste), measures of farmers' economic performance (e.g., bio-economic models), and P governance/policy instruments (e.g., P quota, P tax). To reconcile the economic and ecological sustainability of animal husbandry, the strategic objective of future research will be to provide solutions for a sufficient supply of high-quality animal products from resource-efficient and economically competitive agro-systems which are valued by society and preserve soil and aquatic ecosystems.
