A trial of a job-specific workers' health surveillance program for construction workers: study protocol

<p>Abstract</p> <p>Background</p> <p>Dutch construction workers are offered periodic health examinations. This care can be improved by tailoring this workers health surveillance (WHS) to the demands of the job and adjust the preventive actions to the specific health risks of a worker in a particular job. To improve the quality of the WHS for construction workers and stimulate relevant job-specific preventive actions by the occupational physician, we have developed a job-specific WHS. The job-specific WHS consists of modules assessing both physical and psychological requirements. The selected measurement instruments chosen, are based on their appropriateness to measure the workers' capacity and health requirements. They include a questionnaire and biometrical tests, and physical performance tests that measure physical functional capabilities. Furthermore, our job-specific WHS provides occupational physicians with a protocol to increase the worker-behavioural effectiveness of their counselling and to stimulate job-specific preventive actions. The objective of this paper is to describe and clarify our study to evaluate the behavioural effects of this job-specific WHS on workers and occupational physicians.</p> <p>Methods/Design</p> <p>The ongoing study of bricklayers and supervisors is a nonrandomised trial to compare the outcome of an intervention (job-specific WHS) group (n = 206) with that of a control (WHS) group (n = 206). The study includes a three-month follow-up. The primary outcome measure is the proportion of participants who have undertaken one or more of the preventive actions advised by their occupational physician in the three months after attending the WHS. A process evaluation will be carried out to determine context, reach, dose delivered, dose received, fidelity, and satisfaction. The present study is in accordance with the TREND Statement.</p> <p>Discussion</p> <p>This study will allow an evaluation of the behaviour of both the workers and occupational physician regarding the preventive actions undertaken by them within the scope of a job-specific WHS.</p> <p>Trial registration</p> <p><a href="http://www.trialregister.nl/trialreg/admin/rctview.asp?TC=3012">NTR3012</a></p

Immunological Mechanisms Mediating Hantavirus Persistence in Rodent Reservoirs

Hantaviruses, similar to several emerging zoonotic viruses, persistently infect their natural reservoir hosts, without causing overt signs of disease. Spillover to incidental human hosts results in morbidity and mortality mediated by excessive proinflammatory and cellular immune responses. The mechanisms mediating the persistence of hantaviruses and the absence of clinical symptoms in rodent reservoirs are only starting to be uncovered. Recent studies indicate that during hantavirus infection, proinflammatory and antiviral responses are reduced and regulatory responses are elevated at sites of increased virus replication in rodents. The recent discovery of structural and non-structural proteins that suppress type I interferon responses in humans suggests that immune responses in rodent hosts could be mediated directly by the virus. Alternatively, several host factors, including sex steroids, glucocorticoids, and genetic factors, are reported to alter host susceptibility and may contribute to persistence of hantaviruses in rodents. Humans and reservoir hosts differ in infection outcomes and in immune responses to hantavirus infection; thus, understanding the mechanisms mediating viral persistence and the absence of disease in rodents may provide insight into the prevention and treatment of disease in humans. Consideration of the coevolutionary mechanisms mediating hantaviral persistence and rodent host survival is providing insight into the mechanisms by which zoonotic viruses have remained in the environment for millions of years and continue to be transmitted to humans

The role of stakeholder banks in the European banking systems

Socially oriented financial institutions have an equally long history than profit-oriented financial institutions in Europe. Stakeholder banks occupy a unique and important position in the European banking sector and they have been credited to stabilize the financial market. Changes in financial markets have also caused significant changes in the operations of stakeholder-oriented institutions, leading to significant convergence of the profit-maximizing sector and the stakeholder banks. At the same time, stakeholder banks have remained true to many of their original characteristics. The tensions between regulatory and competitive pressures on the one hand, and the need for a more diverse financial sector on the other hand will continue to characterize the European banking market for years to come.fi=vertaisarvioitu|en=peerReviewed

Prevalência e fatores associados a fogachos em mulheres climatéricas e pós-climatéricas Prevalence and factors associated with hot flashes in climacteric and post-climacteric women

Com o objetivo de determinar a prevalência de fogachos e fatores associados, em mulheres entre 40 e 69 anos de idade, provenientes de uma amostra representativa da população da cidade de Pelotas, Rio Grande do Sul, Brasil, realizou-se um estudo transversal. O processo de amostragem foi em múltiplos estágios, e a coleta de dados, realizada através de entrevista e questionário auto-aplicado. Foram incluídas 879 mulheres. A prevalência ponto e a prevalência de episódio de fogachos foram, respectivamente, de 30,1% e 53,2%. Os fatores estatisticamente associados a fogachos atuais foram a categoria menopausal de pré-menopausa (RP = 2,33) e pós-menopausa (RP = 2,66); idade de 45 a 49 anos (RP = 1,34) e de 50 a 54 anos (RP = 1,42); status sócio-econômico mais baixo (RP = 2,16); não uso de anticoncepção hormonal após os 40 anos (RP = 1,40); obesidade (RP = 1,39); sobrepeso (RP = 1,32) e viver sem companheiro (RP = 0,80). Dada a alta prevalência do sintoma, é necessário que os serviços de saúde se organizem para lidar com a mulher climatérica.<br>A cross-sectional study was conducted on the prevalence of hot flashes and associated factors among women from 40 to 69 years old, from a population-based sample in the city of Pelotas, southern Brazil. A multi-stage sampling process was used, and data were collected through an interview and a self-applied questionnaire. A total of 879 women were included. Point prevalence and lifetime prevalence were 30.1% and 53.2%, respectively. Factors associated with hot flashes were: pre-menopausal status (RP = 2.33) and post-menopausal status (RP = 2.66); age 45-49 years (RP = 1.34) and 50-54 years (RP = 1.42); lower social class (RP = 2.16); no use of a hormonal contraception method after 40 years of age (RP = 1.40); obesity (RP = 1.39) and overweight (RP = 1.32); and not having a partner (RP = 0.80). High prevalence of this symptom indicates that health facilities should be prepared to deal with problems encountered by climacteric women
