International Consensus on Guiding Recommendations for Management of Patients with Nonsteroidal Antiinflammatory Drugs Induced Gastropathy-ICON-G

Introduction: Nonsteroidal anti-inflammatory drugs (NSAIDs), one of the most commonly used medications worldwide, are frequently associated with gastrointestinal adverse events. Primary care physicians often face the challenge of achieving adequate pain relief with NSAIDs, while keeping their adverse events to a minimum. This is especially true when long-term use of NSAIDs is required such as in patients with osteoarthritis and rheumatoid arthritis. To help primary care physicians deal with such challenges more effectively, a panel of expert gastroenterologists came together with the aim of developing practice recommendations. Methods: A modified ‘Delphi’ process was used to reach consensus and develop practice recommendations. Twelve gastroenterologists from nine countries provided their expert inputs to formulate the recommendations. These recommendations were carefully developed taking into account existing literature, current practices, and expert opinion of the panelists. Results: The expert panel developed a total of fifteen practice recommendations. Following are the key recommendations: NSAIDs should be prescribed only when necessary; before prescribing NSAIDs, associated modifiable and non-modifiable risk factors should be considered; H. pylori infection should be considered and treated before initiating NSAIDs; patients should be properly educated regarding NSAIDs use; patients who need to be on long-term NSAIDs should be prescribed a gastroprotective agent, preferably a proton pump inhibitor and these patients should be closely monitored for any untoward adverse events. Conclusion/clinical significance: These practice recommendations will serve as an important tool for primary care physicians and will guide them in making appropriate therapeutic choices for their patients.

Beyond the brotherhood: Skoal Bandits’ role in the evolution of marketing moist smokeless tobacco pouches

Background Since 2006, “snus” smokeless tobacco has been sold in the U.S.. However, U.S. Smokeless Tobacco (USST) and Swedish Match developed and marketed pouched moist snuff tobacco (MST) since 1973. Material and Methods Analysis of previously secret tobacco documents, advertisements and trade press. Results USST partnered with Swedish Match, forming United Scandia International to develop pouch products as part of the “Lotus Project.” Pouched MST was not commonly used, either in Sweden or the U.S. prior to the Lotus Project’s innovation in 1973. The project aimed to transform smokeless tobacco from being perceived as an “unsightly habit of old men” into a relevant, socially acceptable urban activity, targeting 15–35 year-old men. While USST’s initial pouched product “Good Luck,” never gained mainstream traction, Skoal Bandits captured significant market share after its 1983 introduction. Internal market research found that smokers generally used Skoal Bandits in smokefree environments, yet continued to smoke cigarettes in other contexts. Over time, pouch products increasingly featured increased flavor, size, nicotine strength and user imagery variation. Conclusions Marlboro and Camel Snus advertising mirrors historical advertising for Skoal Bandits, designed to recruit new users and smokers subjected to smokefree places. Despite serious efforts, pouched MST marketing has been unable to dispel its association with traditional smokeless tobacco stereotypes as macho and rural. Public education efforts to discourage new users and dual use of MST and cigarettes should emphasize that “new” pouch products are simply repackaging “old” smokeless tobacco

Superconductivity in doped cubic silicon

International audienceAlthough the local resistivity of semiconducting silicon in its standard crystalline form can be changed by many orders of magnitude by doping with elements, superconductivity has so far never been achieved. Hybrid devices combining silicon's semiconducting properties and superconductivity have therefore remained largely underdeveloped. Here we report that superconductivity can be induced when boron is locally introduced into silicon at concentrations above its equilibrium solubility. For sufficiently high boron doping (typically 100 p.p.m.) silicon becomes metallic(1). We find that at a higher boron concentration of several per cent, achieved by gas immersion laser doping, silicon becomes superconducting. Electrical resistivity and magnetic susceptibility measurements show that boron-doped silicon (Si:B) made in this way is a superconductor below a transition temperature T-c approximate to 0.35 K, with a critical field of about 0.4 T. Ab initio calculations, corroborated by Raman measurements, strongly suggest that doping is substitutional. The calculated electron-phonon coupling strength is found to be consistent with a conventional phonon-mediated coupling mechanism(2). Our findings will facilitate the fabrication of new silicon-based superconducting nano-structures and mesoscopic devices with high-quality interfaces
