Official Positions for FRAX® clinical regarding biochemical markers from Joint Official Positions Development Conference of the International Society for Clinical Densitometry and International Osteoporosis Foundation on FRAX®.

The best indirect evidence that increased bone turnover contributes to fracture risk is the fact that most of the proven therapies for osteoporosis are inhibitors of bone turnover. The evidence base that we can use biochemical markers of bone turnover in the assessment of fracture risk is somewhat less convincing. This relates to natural variability in the markers, problems with the assays, disparity in the statistical analyses of relevant studies and the independence of their contribution to fracture risk. More research is clearly required to address these deficiencies before biochemical markers might contribute a useful independent risk factor for inclusion in FRAX(®).

Impact de la prophylaxie hormonale sur les fractures du fémur proximal des femmes postménopausiques: une étude de simulation. [Impact of hormonal prevention on fractures of the proximal femur in postmenopausal women: a simulation study].

A simulation model of the effects of hormone replacement therapy (HRT) on hip fractures and their consequences is based on a population of 100,000 post-menopausal women. This cohort is confronted with literature derived probabilities of cancers (endometrium or breast, which are contra-indications to HRT), hip fracture, disability requiring nursing home or home care, and death. Administration of HRT for life prevents 55,5% of hip fractures, 22,6% of years with home care and 4,4% of years in nursing homes. If HRT is administered for 15 years, these results are 15,5%, 10% and 2,2%, respectively. A slight gain in life expectancy is observed for both durations of HRT. The net financial loss in the simulated population is 222 million Swiss Francs (cost/benefit ratio 1.25) for lifelong administration of HRT, and 153 million Swiss Francs (cost/benefit ratio 1.42) if HRT is administered during 15 years.

Progênies superiores de soja resistentes ao tipo 3 do nematóide de cisto da soja

Os objetivos deste trabalho foram selecionar progênies superiores de soja e avaliá-las, em casa de vegetação, quanto à resistência ao nematóide tipo 3 de cisto da soja (Heterodera glycines). Foram avaliadas 222 progênies segregantes de soja, em ensaios conduzidos em campo, nos anos 1999/2000, 2000/2001 e 2001/2002, sob delineamento de blocos aumentados de Federer, e no ano 2002/2003 em blocos ao acaso, com duas repetições, tendo sido avaliados dez atributos agronômicos. No ano de 2003 foi conduzido em casa de vegetação um ensaio com 11 progênies superiores, para a avaliação de resistência ao nematóide de cisto, adotando-se delineamento inteiramente casualizado, com cinco repetições. Com relação aos atributos agronômicos, as progênies JAB 99-17-4-9-1 e JAB 99-40-12-1-2 destacaram-se das demais por possuir médias adequadas para a maioria dos atributos. Por sua vez, na avaliação de resistência em casa de vegetação, seis progênies revelaram-se resistentes ao nematóide de cisto da soja tipo 3.

Detection of hemorrhage source: the diagnostic value of post-mortem CT-angiography.

The aim of this study was to compare the diagnostic value of post-mortem computed tomography angiography (PMCTA) to conventional, ante-mortem computed tomography (CT)-scan, CT-angiography (CTA) and digital subtraction angiography (DSA) in the detection and localization of the source of bleeding in cases of acute hemorrhage with fatal outcomes. The medical records and imaging scans of nine individuals who underwent a conventional, ante-mortem CT-scan, CTA or DSA and later died in the hospital as a result of an acute hemorrhage were reviewed. Post-mortem computed tomography angiography, using multi-phase post-mortem CTA, as well as medico-legal autopsies were performed. Localization accuracy of the bleeding was assessed by comparing the diagnostic findings of the different techniques. The results revealed that data from ante-mortem and post-mortem radiological examinations were similar, though the PMCTA showed a higher sensitivity for detecting the hemorrhage source than did ante-mortem radiological investigations. By comparing the results of PMCTA and conventional autopsy, much higher sensitivity was noted in PMCTA in identifying the source of the bleeding. In fact, the vessels involved were identified in eight out of nine cases using PMCTA and only in three cases through conventional autopsy. Our study showed that PMCTA, similar to clinical radiological investigations, is able to precisely identify lesions of arterial and/or venous vessels and thus determine the source of bleeding in cases of acute hemorrhages with fatal outcomes.

Dinâmica da água nas palhadas de milho, milheto e soja utilizadas em plantio direto

O objetivo deste trabalho foi avaliar o efeito das palhadas de milho, milheto e soja na capacidade de interceptação e de armazenamento de água, velocidade de dessecamento, porcentagem de cobertura do solo, interceptação da radiação solar e escoamento superficial, assim como incorporar estes efeitos em um modelo de crescimento de plantas. As palhadas de milheto e de milho apresentaram capacidade maior de armazenar água do que a de soja: 3,26, 3,24 e 2,62 g de água por grama de palhada, respectivamente. A quantidade de água perdida pelos resíduos foi proporcional à evapotranspiração potencial. As taxas de cobertura foram equivalentes nos três tipos de material. Os três tipos de palhada foram similares na interceptação das radiações fotossinteticamente ativa e infravermelha. Os resíduos do milheto foram eficientes no controle do escoamento superficial: do total de 843,5 mm de água precipitada, apenas 45,5 mm foram perdidos pelo escoamento superficial no sistema de plantio direto enquanto no convencional as perdas de água foram de 222,5 mm. Os modelos linear e exponencial expressam de forma significativa a maior parte das relações estudadas.

Ultrasound evaluation of synovitis in RA: Correlation with clinical disease activity and sensitivity to change in an observational cohort study.

OBJECTIVE: To evaluate the correlation between clinical measures of disease activity and a ultrasound (US) scoring system for synovitis applied by many different ultrasonographers in a daily routine care setting within the Swiss registry for RA (SCQM) and further to determine the sensitivity to change of this US Score. METHODS: One hundred and eight Swiss rheumatologists were trained in performing the Swiss Sonography in Arthritis and Rheumatism (SONAR) score. US B-mode and Power Doppler (PwD) scores were correlated with DAS28 and compared between the clinical categories in a cross-sectional cohort of patients. In patients with a second US (longitudinal cohort), we investigated if change in US score correlated with change in DAS and evaluated the responsiveness of both methods. RESULTS: In the cross-sectional cohort with 536 patients, correlation between the B-mode score and DAS28 was significant but modest (Pearson coefficient r=0.41, P<0.0001). The same was true for the PwD score (r=0.41, P<0.0001). In the longitudinal cohort with 183 patients we also found a significant correlation between change in B-mode and in PwD score with change in DAS28 (r=0.54, P<0.0001 and r=0.46, P<0.0001, respectively). Both methods of evaluation (DAS and US) showed similar responsiveness according to standardized response mean (SRM). CONCLUSIONS: The SONAR Score is practicable and was applied by many rheumatologists in daily routine care after initial training. It demonstrates significant correlations with the degree of as well as change in disease activity as measured by DAS. On the level of the individual, the US score shows many discrepancies and overlapping results exist.
