Abstract: Osteoporosis is a frequent complication of ankylosing spondylitis (AS), with a prevalence from 19% to 62% dependent upon general factors (age, gender, smoking status), biomechanical aspects, specific character-istics of the disease (such as, a longer disease duration, presence of syndesmophytes, severe extra-articular manifestations or involvement of peripheral joints), and finally, factors related to the pro-inflammatory process with an increased in resorption by osteoclasts associated with the stimuli induced by cytokines. Differences in osteoporosis frequencies are observed when it is evaluated exclusively in the axial skeleton or when it is included the forearm in the measurement of bone mineral density (BMD). Vertebral fractures are relevant complications of osteoporosis in AS, with a prevalence varying from 16 to 32%, although these fractures are frequently misdiagnosed in the clinical practice, observed as an unexpected finding in radiographic studies. More recent diagnostic methods to detect vertebral fractures include vertebral morphometry measured with dual photon X-ray absorption (DXA), with a prevalence of osteoporotic fractures in thoracic and lumbar spine of 19%, whereas, in our center vertebral fractures in have been identified in 32%. Interestingly, a high proportion of patients with osteoporotic vertebral fractures have a normal BMD measurement in their lumbar spine being related to the presence of syndesmophytes that act as an artifact for overestimating the BMD in the lumbar spine. Osteoporotic vertebral fractures are associated with a decrease in the global functional capacity and impairment in spine mobility. A multiplicity of cytokines and other molecules participate in the genesis of osteoporosis in AS and constitute potential targets for present and future therapeutic strategies. TNF-? and interleukin-6 (IL-6) are related to a decrease in BMD in early stages of AS whereas, a decrease in serum levels of sclerostin and Dikkoppf (DKK) have been associated with syndesmophytes and the inhibition of bone mass formation. Several adipokines, including leptin and adiponectin, have been related to abnormalities in BMD in other diseases but their contribution to osteoporosis associated with AS has not yet been evaluated. Bone remodeling markers, such as type I collagen N-terminal propeptide (PINP), have been related to disease duration or age, whereas, markers of bone resorption seem to be related to low BMD, although their predictive value for the development of vertebral fractures is still unclear. Treatment with anti-TNF inhibitors is associated with an increase in BMD and an improvement in serum levels of bone remodeling markers. Since there is not enough evidence to consider that the use of anti-TNF inhibitors constitutes a sufficient strategy to decrease the risk of vertebral fractures in AS patients with osteoporosis, the addition of other therapies are therefore required including vitamin D, calcium supple-ments, antiresorptive therapy with biphosphonates or teriparatide in AS with osteoporosis or with a high risk for osteoporotic fractures. Some biphosphonates such as pamidronate offer benefits in some clinical manifestations, improving axial symptoms and peripheral arthritis. In summary, osteoporosis and vertebral fractures in AS are an exciting research area for evaluation of new therapeutic strategies oriented towards prevention and treatment of this relevant complication in AS.

The Mexican Association of Medical Schools committed to defining a set of national outcomes and standards for all Mexican medical graduates. Methods: During the XLVIII ordinary national meeting of this association, 120 faculty members and deans of medical schools worked collaboratively and identified, by consensus, the preliminary version of the national outcomes and minimum essential requirements, as a means of defining the national outcome-based profile for Mexican medical graduates. Results: The nine outcomes are: (1) clinical skills; (2) communication skills; (3) public health and health systems; (4) scientific bases of medicine; (5) information management; (6) critical thinking and research; (7) teaching skills; (8) administrative and legal aspects of medical practice; and (9) values, attitudes, professionalism, and ethics. Conclusion: The deans and faculty members of the Mexican medical schools are well aware of the diversity in the quality of medical education offered by different schools. The preliminary version of a national set of outcomes has been defined, and a final version will be created during the next national meetings of the Association. The greatest challenge however, will be its implementation into a new educational model in each school.",,,,,,"10.1080/01421590701691411",,,"http://hdl.handle.net/20.500.12104/43439","http://www.scopus.com/inward/record.url?eid=2-s2.0-38849136646&partnerID=40&md5=5fcefbb078372a6f4033ca30a1552038",,,,,,"7",,"Medical Teacher",,"691

Storset, O.",,"2006",,"BACKGROUND: In the Valsartan Antihypertensive Long-term Use Evaluation (VALUE) trial the primary outcome (cardiac morbidity and mortality) did not differ between valsartan and amlodipine-based treatment groups, although systolic blood pressure (SBP) and diastolic blood pressure reductions were significantly more pronounced with amlodipine. Stroke incidence was non-significantly, and myocardial infarction was significantly lower in the amlodipine-based regimen, whereas cardiac failure was non-significantly lower on valsartan. OBJECTIVES: The study protocol specified additional analyses of the primary endpoint according to: sex; age; race; geographical region; smoking status; type 2 diabetes; total cholesterol; left ventricular hypertrophy; proteinuria; serum creatinine; a history of coronary heart disease; a history of stroke or transient ischemic attack; and a history of peripheral artery disease. Additional subgroups were isolated systolic hypertension and classes of antihypertensive agents used immediately before randomization. METHODS: The 15 245 hypertensive patients participating in VALUE were divided into subgroups according to baseline characteristics. Treatment by subgroup interaction analyses were carried out by a Cox proportional hazard model. Within each subgroup, treatment effects were assessed by hazard ratios and 95% confidence intervals. RESULTS: For cardiac mortality and morbidity, the only significant subgroup by treatment interaction was of sex (P = 0.016), with the hazard ratio indicating a relative excess of cardiac events with valsartan treatment in women but not in men, but SBP differences in favour of amlodipine were distinctly greater in women. No other subgroup showed a significant difference in the composite cardiac outcome between valsartan and amlodipine-based treatments. For secondary endpoints, a sex-related significant interaction was found for heart failure (P < 0.0001), with men but not women having a lower incidence of heart failure with valsartan. CONCLUSION: As in the whole VALUE cohort, in no subgroup of patients were there differences in the incidence of the composite cardiac endpoint with valsartan and amlodipine-based treatments, despite a greater blood pressure decrease in the amlodipine group. The only exception was sex, in which the amlodipine-based regimen was more effective than valsartan in women, but not in men, whereas the valsartan regimen was more effective in preventing cardiac failure in men than in women.
