Omega-3 polyunsaturated acids and cardiovascular disease: notable ethnic differences or unfulfilled promise?

Summary., The consumption of long chain omega-3 polyunsaturated acids (PUFA) is considered to protect against cardiovascular disease and promote longevity following a heart attack. Historically, research in this area was fuelled by compelling reports of the cardiovascular benefits of omega-3 PUFA in select populations and cultures. More recent studies, in wider populations, suggest discordant findings: differences that are difficult to reconcile as the mechanism of action of omega-3 PUFA are poorly understood. As such, the use of this ,natural treatment' for cardiovascular disease is increasingly controversial, and potentially one of unfulfilled promise. To what extent does ethnicity influence the impact that omega-3 PUFA have on cardiovascular disease and its associated complications? We were interested to review the benefits of omega-3 PUFA in the management of cardiovascular risk amongst diverse ethnic groups. Using a systematic review of literature relating to omega-3 PUFA and cardiovascular disease, we found ethnicity to be a factor that accounts for inconsistency between studies. Some of the effects of omega-3 PUFA are limited to cultures with a very high omega-3 intake, and in turn, ethnicity moderates the efficiency with which PUFA are derived from the diet. Moreover, omega-3 PUFA are an important health care intervention in the current climate of globalization, where supplementation is likely to give protection to cultural groups undergoing dietary transition. Future epidemiological research into the efficacy of omega-3 PUFA in cardiovascular disease should consider the influence of ethnicity. [source]

Review article: endoscopic antireflux procedures , an unfulfilled promise?

Summary Background, Most published reviews concerning the endoscopic treatment of gastro-oesophageal reflux disease date back to 2005. Aim, To provide an updated review that includes all papers published up to 2007. Methods, A Medline search from January 2005 to June 2007 was performed regarding endoscopic procedures aiming at treating gastro-oesophageal reflux disease. In addition, we retrieved the abstracts presented at Digestive Disease Week during the last 3 years. We included in the review both ,mechanistic' studies , that is, papers exploring the potential mechanism of action of the procedure/device , and studies trying to assess its clinical efficacy. Results, During the last 3 years, the number of published papers has declined, and some devices are not available any more. The alleged mechanism(s) of action of the various devices or procedures is (are) still not completely elucidated; however, some concerns have arisen as far as durability and potential detrimental effects. Moreover, all the aspects of endoscopic therapy, except for its safety, are either insufficiently explored or not investigated at all, or assessed only in particularly selected patient subgroups. Conclusions, None of the proposed antireflux therapies has fulfilled the criteria of efficacy, safety, cost, durability and, possibly, of reversibility. There is at present no definite indication for endoscopic therapy of gastro-oesophageal reflux disease. We suggest a list of recommendations to be followed when a new endoscopic therapeutic procedure is to be assessed for use in clinical practice. [source]

Promises Made, Promises Broken: An Exploration of Employee Attraction and Retention Practices in Small Business

Jill Kickul
Entrepreneurial organizations have undergone substantial workforce changes and transformations during the last two decades in order to compete successfully on a global scale. The ability to attract and retain reliable and competent employees has become a key component in developing an effective and sustainable competitive advantage. The purpose of this study is to investigate the role of the psychological contract and the types of promises made and communicated by small business organizations to attract and retain their employees. From a sample of 151 employees within small businesses, the results demonstrate that perceived unfulfilled promises can have a considerable impact on workplace attitudes, commitment, and intentions to leave the organization. Implications and recommendations for small businesses as well as directions for future research are discussed. [source]
