[Risk assessment comparison of biomechanical overloading of the musculoskeletal system: 10 years' applied experience]

Unlabelled: Risk assessment for upper extremity work related muscoloskeletal disorders by applying six methods of ergonomic: a ten years experience. The objective of this research was to verify and validate the multiple step method suggested by SIMLII guidelines and to compare results obtained by use of these methods: Washington State Standard, OCRA, HAL, RULA, OREGE and STRAIN INDEX. Methods: 598 workstations for a total of 1800 analysis by different methods were considered, by adopting the ...

Does treatment assignment influence the prognosis of patients with symptomatic severe aortic stenosis?

Objective: Aortic valve replacement (AVR) is the standard therapy in patients with symptomatic aortic stenosis (AS). In high surgical risk patients, alternative therapeutic options to medical treatment (MT) such as trans-catheter aortic valve implantation (TAVI) or balloon aortic valvuloplasty (BAV) have been proposed. In this study we evaluated whether treatment assignment influences per se the prognosis of these subjects. Patients and methods: Criteria for treatment assignment were based on...

[Considerations on the use of meta-analyses in the orientation of knowledge and decisions in Occupational Medicine]

: In recent years, due to the need to elaborate the amount of information available from the scientific literature, the meta-analyses and systematic reviews have become very numerous. The meta-analyses are carried out to evaluate the association between two events when single researches haven't provided comprehensive data. On the other hand, a good meta-analysis must satisfy certain criteria, from the selection of the studies until the evaluation of the outcomes; to this purpose, the applicat...
