VTE, the formation of blood clots in the veins, develops in up to 20 percent of cancer patients and is one of the leading causes of death among this patient population. Patients with hematologic malignancies (blood cancers), particularly those with lymphoma and multiple myeloma, have relatively high rates of VTE—results from this study found that 7.2 percent of lymphoma patients and 7.4 percent of the total study population developed VTE, compared to an estimated general population incidence rate of .001 percent.1
"Because the risk of VTE is not equal in all cancer patients and anticoagulation in cancer patients results in a higher risk of bleeding complications, categorizing cancer patients according to their VTE risk is important," said Ingrid Pabinger, MD, professor at the Medical University of Vienna and lead author of the study. Patients with high risk of VTE may benefit from routine thrombophrophylaxis, preventive treatment for blood clotting, while low-risk patients tend to have a higher bleeding risk and may not be the best candidates for routine anticoagulation treatments.
Although there is a current risk prediction model for VTE in cancer patients, which includes factors such as site of cancer, body mass index, platelet and leukocyte counts, and hemoglobin level—all known to increase the risk of cancer-associated VTE—the new model also incorporates two new biomarkers, soluble P-selectin (sP-selectin) and D-dimer, to further stratify patients into high- and low-risk groups. sP-selectin is a cell adhesion molecule that promotes blood clot formation and D-dimer is a protein found in the blood that is used to detect abnormal blood clot formation and breakdown. Both have been previously identified as predictive biomarkers for cancer-associated VTE and their addition into the risk prediction model improves the accuracy of the classification of the patients into different risk categories. According to this new risk scoring model, about one-third (35 percent) of cancer patients in the highest risk category developed VTE during the study, as opposed to only one percent of patients in the lowest risk category.
In this study, researchers examined 819 cancer patients enrolled in the Vienna Cancer and Thrombosis Study (CATS), an ongoing prospective observational study performed at the Medical University of Vienna, between October 2003 and December 2008. Cancer types included: brain, breast, lung, stomach, colorectal, pancreatic, kidney, prostate, and hematologic malignancies such as myeloma and lymphoma.
"Our expanded model demonstrates that cancer patients at a very high risk of VTE can be defined more precisely," said Cihan Ay, MD, hematology fellow at the Clinical Division of Hematology and Hemostaseology at the Medical University of Vienna and co-author of the study. "This new model can help clinicians tailor their anticoagulant therapy and improve blood clotting prevention, which will maximize the clinical benefit and cost-effectiveness of disease prevention and minimize the risk of bleeding complications."

The American Society of Hematology is the world's largest professional society concerned with the causes and treatment of blood disorders. Its mission is to further the understanding, diagnosis, treatment, and prevention of disorders affecting blood, bone marrow, and the immunologic, hemostatic, and vascular systems by promoting research, clinical care, education, training, and advocacy in hematology. ASH provides Blood: The Vital Connection, a credible online resource addressing bleeding and clotting disorders, anemia, and cancer. The official journal of ASH is Blood, the most cited peer-reviewed publication in the field, which is available weekly in print and online.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
