Les communautés de pratique des infirmiers et infirmières sur internet : quelles contributions dans la construction de praxéologies professionnelles ?

Le secteur de la santé n'échappe pas à la généralisation de l'usage de l'informatique et à l'utilisation des TIC dans de nombreuses applications. Les infirmiers sont des acteurs du secteur confrontés à un usage toujours plus important. Nous interrogeons donc la place des TIC dans la construction professionnelle des infirmiers. Une enquête par questionnaire a été menée auprès d'infirmiers en activité, de cadres de santé formateurs et d'étudiants en soins infirmiers pour sonder leurs usages de l'internet dans leur pratique professionnelle et leur formation. Les résultats montrent que les réseaux sociaux ont bien une place dans les échanges, surtout entre étudiants et professionnels de santé

Merck Animal Health Uses Operations Research Methods to Transform Biomanufacturing Productivity for Lifesaving Medicines

Merck Animal Health offers veterinarians, farmers, pet owners, and governments a wide range of veterinary pharmaceuticals, vaccines, health management solutions and services, and an extensive suite of connected technology that includes identification, traceability, and monitoring products. Biomanufacturing uses living organisms (i.e., viruses and bacteria) to grow the active ingredients in vaccines, pharmaceuticals, and therapeutics. This high-tech manufacturing process generates unique challenges not found in many other industries. For example, biomanufacturing operations include high levels of uncertainty and batch-to-batch variability in production yield, lead times, and costs. Additionally, the high cost of equipment and labor-intensive nature of operations preclude the ability to flexibly add capacity. Facing these challenges, we decided that harnessing the power of operations research and advanced analytics to complement our rich life sciences and biomanufacturing expertise was critical. After four years of collaboration with the Eindhoven University of Technology, we developed a portfolio of optimization models and decision support applications that substantially improved our biomanufacturing effectiveness. The implementation of the developed models had a significant impact by generating $200 million of additional revenue without the need for additional raw materials, energy resources, or new equipment. The developed models are widely adopted across the firm, thus enhancing its core function

Scrotal metastases from colorectal carcinoma: a case report

A 72-year-old man presented with a two month history of rectal bleeding. Colonoscopy demonstrated synchronous lesions at 3 cm and 40 cm with histological analysis confirming synchronous adenocarcinomata. He developed bilobar hepatic metastases while undergoing neoadjuvant chemoradiotherapy. Treatment was complicated by Fournier's gangrene of the right hemiscrotum which required surgical debridement. Eight months later he re-presented with an ulcerating lesion on the right hemiscrotum. An en-bloc resection of the ulcerating scrotal lesion and underlying testis was performed. Immunohistological analysis revealed metastatic adenocarcinoma of large bowel origin. Colorectal metastasis to the urogenital tract is rare and here we report a case of rectal carcinoma metastasizing to scrotal skin

From Social Data Mining to Forecasting Socio-Economic Crisis

Socio-economic data mining has a great potential in terms of gaining a better understanding of problems that our economy and society are facing, such as financial instability, shortages of resources, or conflicts. Without large-scale data mining, progress in these areas seems hard or impossible. Therefore, a suitable, distributed data mining infrastructure and research centers should be built in Europe. It also appears appropriate to build a network of Crisis Observatories. They can be imagined as laboratories devoted to the gathering and processing of enormous volumes of data on both natural systems such as the Earth and its ecosystem, as well as on human techno-socio-economic systems, so as to gain early warnings of impending events. Reality mining provides the chance to adapt more quickly and more accurately to changing situations. Further opportunities arise by individually customized services, which however should be provided in a privacy-respecting way. This requires the development of novel ICT (such as a self- organizing Web), but most likely new legal regulations and suitable institutions as well. As long as such regulations are lacking on a world-wide scale, it is in the public interest that scientists explore what can be done with the huge data available. Big data do have the potential to change or even threaten democratic societies. The same applies to sudden and large-scale failures of ICT systems. Therefore, dealing with data must be done with a large degree of responsibility and care. Self-interests of individuals, companies or institutions have limits, where the public interest is affected, and public interest is not a sufficient justification to violate human rights of individuals. Privacy is a high good, as confidentiality is, and damaging it would have serious side effects for society.Comment: 65 pages, 1 figure, Visioneer White Paper, see http://www.visioneer.ethz.c
