Detection of influenza D virus in bovine respiratory disease samples, UK.

Influenza D is a newly described virus of cattle, pigs and small ruminants first detected in North America during 2011. Cattle have been shown to be the main viral reservoir and mounting evidence indicates that infection with influenza D may contribute to the development of bovine respiratory disease. The virus has been detected across the United States, Europe and Asia.

Cost-effectiveness of rivaroxaban in the prevention of venous thromboembolism: A Canadian analysis using the Ontario Ministry of Health Perspective.

Objectives: A cost-effectiveness model for rivaroxaban evaluated the cost-effectiveness of prophylaxis with rivaroxaban (a once-daily, orally administered Factor Xa inhibitor) vs enoxaparin in the prevention of venous thromboembolism (VTE) after total hip replacement (THR) and total knee replacement (TKR). This Canadian analysis was conducted using the Ontario Ministry of Health perspective over a 5-year time horizon. The model combined clinical data and builds upon existing economic models.

Cost effectiveness of rivaroxaban versus enoxaparin for prevention of post-surgical venous thromboembolism from a U.S. payer's perspective.

Background: Major orthopaedic surgery, such as total hip replacement (THR) and total knee replacement (TKR), is associated with an increased risk of venous thromboembolism (VTE).

Objective: Clinical trials have demonstrated the efficacy of rivaroxaban, a once-daily, orally administered Factor Xa inhibitor, for the prevention of VTE in patients undergoing THR or TKR. This analysis evaluated the cost effectiveness of rivaroxaban compared with enoxaparin, from a U.

Cost and outcomes associated with rivaroxaban vs enoxaparin for the prevention of postsurgical venous thromboembolism from a US payer's perspective.

Objective: The objective of this analysis was the evaluation of the outcomes and costs associated with rivaroxaban and enoxaparin for the prevention of postsurgical venous thromboembolism (VTE) in patients undergoing total hip replacement (THR) and total knee replacement (TKR) from the US payer perspective.

Methods: VTE event rates have been reported in three Phase III clinical trials that compared rivaroxaban and enoxaparin for VTE prevention after orthopedic surgery during the prophylaxis (≤35 days for THR patients and 10-14 days for TKR patients) and post-prophylaxis periods (≤90 days following surgery). These data were used in this decision-analytic model to estimate and compare health outcomes and costs associated with rivaroxaban and enoxaparin.

Cost-effectiveness of rivaroxaban versus heparins for prevention of venous thromboembolism after total hip or knee surgery in Sweden.

Aims: The objective of this study was to evaluate the cost-effectiveness of rivaroxaban versus the low-molecular-weight heparins (LMWH) enoxaparin and dalteparin for the prevention of venous thromboembolism (VTE) after total hip replacement and total knee replacement in Sweden.

Methods: The model included acute venous thromboembolic events and long-term complications over a 5-year time horizon represented by an acute and a chronic phase with 1-year cycles. Transition probabilities were derived from the Regulation of Coagulation in Orthopaedic Surgery to Prevent Deep Vein Thrombosis and Pulmonary Embolism (RECORD) clinical trials.

Genotyping of Toxoplasma gondii isolates in meningo-encephalitis affected striped dolphins (Stenella coeruleoalba) from Italy.

This study reports the occurrence of Toxoplasma gondii in the brain of three striped dolphins (Stenella ceoruleoalba) found stranded on the Ligurian Sea coast of Italy between 2007 and 2008. These animals showed a severe, subacute to chronic, non-purulent, multifocal meningo-encephalitis, with the cerebral parenchyma of two dolphins harbouring protozoan cysts and zoites immunohistochemically linked to T. gondii.

Quantifying the economic burden of productivity loss in rheumatoid arthritis.

Objective: In light of the large number of recent studies and systematic reviews investigating the cost of RA, this article examines the methods used to assess the impact of RA on employment and work productivity, and provides an overview of the issues surrounding work productivity loss in the RA population.

Methods: A review of the published literature was conducted in order to identify relevant articles. These articles were then reviewed and their methodologies compared.

Cost-effectiveness of rivaroxaban versus enoxaparin for the prevention of postsurgical venous thromboembolism in Canada.

This study aimed to evaluate the cost-effectiveness of prophylaxis with rivaroxaban vs. enoxaparin in the prevention of venous thromboembolism (VTE) after total hip replacement (THR) and total knee replacement (TKR) from the perspective of the Canadian healthcare system. A model was developed that included both acute VTE (represented as a decision tree) and long-term complications (represented as a Markov process with one-year cycles).

Modulation of immune responses to Mycobacterium bovis in cattle depleted of WC1(+) gamma delta T cells.

It is accepted that cell-mediated immune responses predominate in mycobacterial infections. Many studies have shown that CD4(+) T cells produce Th1 cytokines, such as gamma interferon (IFN-gamma), in response to mycobacterial antigens and that the cytolytic activity of CD8(+) cells toward infected macrophages is important. However, the extent and manner in which gamma delta T cells participate in this response remain unclear.
