Production of high quality precooked, frozen foods requires constant vigilance by the producer, handler, and user. The history of quality assurance is described. A program of total quality assurance for the food processor is detailed. Environmental sanitation and microbiological control is discussed.

Successful completion of any study is the timely preparation and distribution of an accurate, understandable, and useful report. The report should include all details of study procedures and results plus conclusions based on thoughtful consideration of the data. Overall, responsibility for a study report should belong to the study director. Contributing scientists and scientific writers should work closely with the study director in establishing timing and format. Review by one or more peers is an effective means of assuring that the report is scientifically valid and that conclusions drawn are sound and accurate. Review by the quality assurance unit (QAU) helps assure that the report accurately reflects the raw data and that all pertinent data are included in the report. However, although the foregoing are necessary, they are not sufficient. It is crucial that the study director and other report contributors have a clear understanding of the expectations and needs of the sponsor before the report is assembled. A total quality approach to planning and preparing the report will result in a high-quality document.

BS5750 is the British Standard on “Quality Systems”. Its equivalent in European Standards is EN29000 and in the International Standards Organisation ISO9000. This paper points out that these standards lay down formalised procedures and require documentation but do not ipso facto lead to quality assurance. The author points to the Japanese post-war industrial success as being an example of Total Quality Management within the framework provided by the philosophy of Dr. W. Edwards Deming (1988 and 1993). This philosophy on the management of “systems” to provide high quality products and services is briefly outlined. The author argues that improvement in prosthetic and orthotic services will not be reached through implementation of BS5750 but rather through radical rethinking and the adoption and application of the Deming philosophy.

The production of high-quality seed is the basis for a durable a profitable agriculture. After production, seed is processed, conditioned, stored, shipped and germinated. For quality assurance, seed quality has to be controlled at all steps of the production chain. Seed functioning is accompanied by programmed transitions from cell proliferation to quiescence upon maturation and from quiescence to reinitiation of cellular metabolism upon imbibition. Despite the obvious importance of these control mechanisms, very little information is available at the molecular level concerning those elements that regulate seed germination. In the present study, the induction of cell cycle activity and the regulation of ß-tubulin expression is related to the water content and other physical properties of the seed.

Abstract Background Ulcerative colitis (UC) has been associated with an increased risk of colorectal cancer (CRC). Although dye spray chromoendoscopy showed superiority to standard colonoscopy in surveillance studies, with the availability of higher-resolution colonoscopes, the utility of chromoendoscopy (CE) has been questioned. We aimed to evaluate the risk of intraepithelial neoplasia (IN) after a high-quality screening colonoscopy (making use of CE or random biopsies (RB) and removing all detected lesions) in a population with longstanding UC and to identify potential risk factors for dysplasia incidence. Methods In a previous study, 145 patients with clinically and endoscopic longstanding (≥8 yr) distal/extensive UC without primary sclerosing cholangitis and/or history of IN were prospectively randomised to undergo CE or RB. In this study, after a median follow-up of 5 additional years, we evaluated subsequent IN incidence in these patients, submitted to surveillance colonoscopy. Patients without high-quality surveillance colonoscopy (with good bowel preparation and cecum intubation) using high-definition were excluded. Results One hundred and twenty-one patients were included. Nine had removed adenomas with low-grade dysplasia in the index colonoscopy. Now, in surveillance colonoscopy, we detected 9 (7.4%) IN: low-grade dysplasia was found in 8 (6.6%) patients and a colorectal adenocarcinoma in 1 (0.008%) patient. After multivariate analysis, IN was significantly associated with older age (68 vs. 52 years, p < 0.05) and higher disease duration (26 vs. 20 years, p < 0.05). No association was found between IN and previous detection of IN in screening colonoscopy sex, the CE or RB use in index colonoscopy, extent of disease, The presence of pseudopolyps, smoking habits, familial history of CRC or maintenance therapy for UC. Conclusion In this study, older patients and higher disease duration were associated with a higher risk of IN in surveillance colonoscopy.
