Participatory Ergonomics: A Model for the Prevention of Occupational Musculoskeletal Disorders
2009
La ergonomía participativa es una estrategia de intervención sobre los riesgos por carga física en los lugares de trabajo escasamente conocida en España, aunque en otros países se cuenta con numerosas experiencias y evidencias en este campo. Son varias las razones que justifican su interés. En primer lugar, aborda una de las categorías de riesgos laborales que mayor impacto tiene sobre la salud de los trabajadores en la mayoría de países, tanto en términos de incidencia, como de prevalencia o incapacidad. En segundo lugar, el principio básico de la ergonomía participativa es la capacitación de los trabajadores para que participen tanto en la identificación de los riesgos y daños a la salud …
Effects of different backpack loads in acceleration transmission during recreational distance walking
2013
It is well established nowadays the benefits that physical activity can have on the health of individuals. Walking is considered a fundamental method of movement and using a backpack is a common and economical manner of carrying load weight. Nevertheless, the shock wave produced by the impact forces when carrying a backpack can have detrimental effects on health status. Therefore, the aim of this study was to investigate differences in the accelerations placed on males and females whilst carrying different loads when walking. Twenty nine sports science students (16 males and 13 females) participated in the study under 3 different conditions: no weight, 10% and 20% body weight (BW) added in …
Diagnosis and Planning in Immediate Loading: Surgical Diagnosis
2019
For several decades, two-dimensional images were the only available for the surgical diagnosis prior to implant placement. The introduction of digital radiology and software applications for three-dimensional imaging has increased the prospects of success in implant diagnosis and surgical placement. The CBCT is definitely more precise and complete than panoramic radiography, but it is not always mandatory for every case. Success for fixed implant-supported rehabilitations, especially in immediate provisionalization techniques, depends on accurate pre-surgical evaluation of the following issues: (1) recognize feasible restoration procedures to rehabilitate patient edentulism; (2) list all th…
Phase III, Multicenter Open-Label Study to Investigate the Efficacy of Elbasvir and Grazoprevir Fixed-Dose Combination for Eight Weeks in Treatment-N…
2020
Background: Genotype 1b is the most common HCV genotype worldwide, accounting for the largest proportion of infections in Europe, Russia, Latin America and Asia. Reducing treatment duration can improve adherence, reduce drug exposure and cost. Accordingly, we evaluated the efficacy of eight weeks fixed dose combination of grazoprevir-elbasvir in treatment-naive patients, with non-severe fibrosis. Methods: HCV mono-infected and treatment naive patients with non-severe fibrosis (Fibroscan®<9·5kPa and Fibrotest®<0·59) were enrolled in a study which included 117 patients. Genotyping by sequencing identified five patients with non-1b genotype (two GT1a, one GT1h, one GT1e and one GT1l). Thus, we…
Radiation exposure to the hands and the thyroid of the surgeon during intramedullary nailing.
1998
Abstract During 41 procedures of intramedullary nailing of femoral and tibial fractures, the primary surgeon and the first assistant wore ring dosimeters on their dominant index fingers. While the average fluoroscopy time per procedure was 4.6 min, the average dose of radiation to the dominant hand of the primary surgeon was 1.27 mSv and 1.19 mSv to the first assistant. The dose limit for the extremities is 500 mSv per year, as recommended by the International Commission on Radiological Protection. Extrapolation of the mean dose of the primary surgeon and first assistent per procedure of 1.23 mSv leads to the result that the recommended dose limit of 500 mSv would only be exceeded if more t…
Self-selected running gait modifications reduce acute impact loading, awkwardness, and effort
2021
Impact loading has been associated with running-related injuries, and gait retraining has been suggested as a means of reducing impact loading and lowering the risk of injury. However, gait retraining can lead to increased perceived awkwardness and effort. The influence of specifically trained and self-selected running gait modifications on acute impact loading, perceived awkwardness and effort is currently unclear. Sixteen habitual rearfoot/midfoot runners performed forefoot strike pattern, increased step rate, anterior trunk lean and self-selected running gait modifications on an instrumented treadmill based on real-time biofeedback. Impact loading, perceived awkwardness and effort scores…
Overview of health care provision for adult congenital heart disease (ACHD) in Central and South-eastern European countries: current status, provisio…
2020
Abstract Background Most of North and Western European countries recognized long ago the importance of specialized ACHD programmes and have today well-established Centre of excellence for management of ACHD patients. In contrast, even though Central and South-eastern (CESE) European region geographically comprise almost half of the European continent, little is known about ACHD status in vast majority of its countries. Purpose We aim to provide for the first time contemporary comprehensive overview of ACHD situation in CESE Europe. Methods We obtained data regarding current national ACHD status from 19 CESE European countries. Over the country national cardiac society, the ESC Working Group…
Analgosedierung mit Fentanyl/Midazolam nach Korrektur angeborener Herzfehler
1995
Abstract There is no standard therapy in the management of postoperative pain control following corrective cardiac surgery of congenital heart disease. Assessment in the preverbal age is difficult. In a randomized study we compared a combined treatment of fentanyl and midazolam, given as continuous infusion versus single dose application. A pain assessment score was used to measure the effectiveness of analgosedation in addition to recording nurseries observations. Fentanyl and midazolam are an appropriate combination for postoperative pain treatment. Continuous application is considered to be more effective concerning basic anxiety, cumulative dosage and to avoid volume overload in infants…
Forefoot strikers exhibit lower running-induced knee loading than rearfoot strikers.
2013
AB Purpose: Knee pain and Achilles tendinopathies are the most common complaints among runners. The differences in the running mechanics may play an important role in the pathogenesis of lower limb overuse injuries. However, the effect of a runner's foot strike pattern on the ankle and especially on the knee loading is poorly understood. The purpose of this study was to examine whether runners using a forefoot strike pattern exhibit a different lower limb loading profile than runners who use rearfoot strike pattern. Methods: Nineteen female athletes with a natural forefoot strike (FFS) pattern and pair-matched women with rearfoot strike (RFS) pattern (n = 19) underwent 3-D running analysis …
Predicting sustained virological responses in chronic hepatitis C patients treated with peginterferon alfa-2a (40 KD)/ribavirin.
2005
Background/Aims: Prediction of sustained virological response (SVR) during treatment would allow clinicians to identify patients most likely to benefit from therapy. Methods: Retrospective analysis of data from 1121 adults with chronic hepatitis C treated for 48 weeks with peginterferon alfa-2a (40 KD) 180 mu g/week plus placebo or ribavirin (1000/1200 mg/day), or interferon alfa-2b 3 MIU three times/week plus ribavirin in a randomized, multinational, study. Results: 67% of patients treated with peginterferon alfa-2a (40 KD)/ribavirin with early virological responses (HCV RNA negative or >= 2 log(10) decrease) at week 12 had SVRs at week 72 (HCV RNA 80 % of the planned ribavirin dose.
