From EBM to EBL: two steps forward or one step back?

The author employs his vantage point as a contributor to Evidence-based Medicine (EBM) and Evidence-based Librarianship (EBL) in the United Kingdom to anticipate obstacles to be overcome by the emerging EBL paradigm. After reviewing and synthesizing three proto-definitions of EBL, he discusses issues around the potential domains to be populated by research findings. He then briefly considers the contribution that critical appraisal skills can make to an evidence-based profession. In concluding that "evidence-based librarianship" is a self-limiting "label," he encourages health information professionals instead to promote the contribution of librarianship to evidence-based practice, a role for which they are uniquely qualified.     

A brief history of x-rays

The identity of x-rays was initially mysterious, their connotations including morbidity and the otherworldly. Gradually they became routine, finding a place in the high-energy end of the electromagnetic spectrum. Radiologists established a niche in hospitals, contributing to the industrialization of healthcare. Control of x-ray tube output was improved while an infrastructure enforcing radiation protection accompanied the continued growth of the field. X-ray diffraction proved a powerful tool with which to examine substances at the atomic scale. Since 1950, x-ray researchers have taken advantage of synchrotrons’ copious production of continuous x-ray spectra, and the marriage of x-rays with electronics has led to a cornucopia of cheap and highly efficient analytical tools.     

The type,amount, frequency and timing of dietary supplement use by elite players in the First Spanish Basketball League

The aims of this study were to determine the type, frequency and amount of dietary supplement consumption among a group of professional basketball players. The type, amount and specific timing of supplement use were recorded by 55 professional basketball players from seven different teams of the First Spanish Basketball League. Most participants (58%) consumed dietary supplements. Multivitamins and vitamins were the most frequently used supplements among the athletes (50.9%), followed by sport drinks (21.8%), miscellaneous supplements (21.8%), amino acids (14.5%), proteins (12.7%) and carbohydrates (12.7%). The average daily dietary supplement was one capsule of multivitamins, one capsule of antioxidant vitamins, 0.2-1.0 g vitamin C, 10.3 g protein, 1.9 g amino acids, 16.2 g carbohydrates and 377 ml of a commercial sport drink. Although the proportion of participants who consumed dietary supplements before, during and immediately after exercise was 25.4%, 16.3% and 7.3% respectively, only a few consumed a potentially ergogenic supplement at these times. It would appear unlikely that the type or amount of dietary supplements consumed had a beneficial effect on the physical performance of these professional basketball players, with the possible exception of antioxidant vitamins and the commercial sport drinks.
