BACKGROUND Methicillin-resistant Staphylococcus aureus (MRSA) poses an increasingly large disease and economic burden worldwide. The effectiveness of screening programs in the tropics is poorly understood. The aims of this study are: (i) to analyze the factors affecting MRSA colonization at admission and acquisition during hospitalization and (ii) to evaluate the cost-effectiveness of a screeni...

OBJECTIVES To review studies on the cost consequences of compliance and/or persistence in cardiovascular disease (CVD) and related conditions (hypertension, dyslipidaemia, diabetes and heart failure) published since 1995, and to evaluate the effects of noncompliance on healthcare expenditure and the cost-effectiveness of pharmaceutical interventions. METHODS English language papers published ...

To every matroid, we associate a class in the K-theory of the Grassmannian. We study this class using the method of equivariant localization. In particular, we provide a geometric interpretation of the Tutte polynomial. We also extend results of the second author concerning the behavior of such classes under direct sum, series and parallel connection and two-sum; these results were previously o...

Abstract Three-dimensional (3D) magnetic resonance imaging (MRI) of the knee is widely used in musculoskeletal (MSK) imaging. Currently, 3D sequences are most commonly for morphological Isotropic MRI provides higher out-of-plane resolution than standard two-dimensional (2D) MRI, leading to reduced partial volume averaging artifacts and allowing multiplanar reconstructions any plane with thickne...

abstract background and objective: according to the issue of dependence and tolerance in addicted patients, the inefficiency of existing treatments and the new recommendation for drug combination therapy for diseases in modern pharmacology, the present study examined the effect of methadone and valproate combination on morphine dependence and tolerance. materials and methods: ninety-eight male ...

minimizing production costs for a certain amount of product is one of the main concerns for managers of agricultural and animal husbandry units. much of the cost of a unit of livestock (almost 75%) is related to methods of nutrition and ration. accordingly, using some methods to reduce costs, including methods of mathematical programming, is required. the linear programming model was used as th...

Nitrogen (N) immobilisation by heterotrophic microorganisms is critical for reducing N losses from soils and ensuring a long-term supply of to plants in grassland ecosystems. The carbon (C) available soil microbes may stimulate the availability ammonium autotrophic nitrifiers and, hence, nitrification activity. main source C rhizodeposition, but its effects on activity remain unclear as rhizode...
