Sterilisation is a critical and integral stage in the manufacture of a sterile device. It should, therefore, be recognised at the design stage of the device if the desired confidence in the end product and potential benefits of sterilisation options are to be achieved. This article highlights some of the issues to consider when selecting the most appropriate sterilisation method.
Controlling sterilization costs is a necessity if medical device manufacturers are to remain competitive. This article looks at ways the industry can reduce these costs and also considers the benefits to be gained by improving relationships with sterilization contractors.
The management of obesity is increasingly dominated by nonprofessional self-helping groups. Little information about the efficacy of these groups is available from independent sources. In a study of 108 women enrolled in a commercial weight reduction program, we found very high attrition rates; 50% of the members dropped out in six weeks and 70% in 12 weeks. Similar attrition rates have been reported in five other programs in three different countries. Very high attrition rates diminish the effectiveness of commercial weight reduction programs, and they suggest caution in the interpretation of data based on weight losses of persons who remain in these programs.
