Pressão arterial entre trabalhadores de curtume

INTRODUÇÃO: O grupo das doenças cardiovasculares tem sido apontado como a principal causa de óbito no Brasil desde os anos 70, sendo a hipertensão arterial sistêmica (HAS) o fator de risco mais importante para esse grupo. Entre os trabalhadores observa-se correlação negativa entre o status ocupacional e a pressão arterial. Tais fatos ressaltam a importância do conhecimento da distribuição da pressão arterial sistêmica entre os distintos grupos profissionais. Assim, foi realizado estudo para descrever o status pressórico de uma população homogênea e estável de trabalhadores do setor secundário da economia, pouco especializados e que ganham baixos salários, estabelecendo a prevalência da HAS nesse grupo específico, relacionando-a com algumas covariáveis biológicas e socioeconômicas, e comparando-a com a prevalência de HAS em outros grupos profissionais no Brasil. MÉTODO: Foram estudados 73 trabalhadores regularmente empregados em julho de 1993 em um curtume situado no Município de Botucatu, cidade de médio porte da região Centro-Oeste do Estado de São Paulo, os quais foram submetidos a exame antropométrico, aferição de pressão arterial, anamnese e exame clínico. Os resultados foram comparados com os obtidos em estudos semelhantes, controlando-se o confundimento da idade por intermédio de diferentes técnicas. RESULTADOS: A prevalência bruta da HAS encontrada foi de 56,1%, sendo 15,8% a prevalência de hipertensão sistólica isolada. Ambas se associaram ao etilismo e ao tabagismo na população estudada. DISCUSSÃO: A prevalência da hipertensão foi consideravelmente alta e significativamente maior do que a encontrada em outros grupos de trabalhadores estudados no Brasil. Tal achado ressalta a necessidade da continuidade da investigação, objetivando o isolamento dos fatores implicados na elevação pressórica do grupo estudado.

Incidence of high blood pressure in a group of tannery workers in Brazil

O objetivo deste estudo foi medir a incidência de hipertensão arterial sistêmica em um curtume de médio porte em Botucatu, São Paulo, Sudeste do Brasil, onde havia sido observada, em estudo prévio, uma correlação positiva entre tempo de trabalho e níveis pressóricos, bem como uma alta prevalência de hipertensão. Para tanto, uma coorte de trabalhadores desse curtume foi acompanhada durante sete anos. Ao final do seguimento, estimou-se a taxa de incidência de hipertensão arterial como 0,0964.ano-1, valor considerado elevado se comparado com o encontrado em outros grupos profissionais.

The CUPID (Cultural and Psychosocial Influences on Disability) Study: Methods of Data Collection and Characteristics of Study Sample

Background: The CUPID (Cultural and Psychosocial Influences on Disability) study was established to explore the hypothesis that common musculoskeletal disorders (MSDs) and associated disability are importantly influenced by culturally determined health beliefs and expectations. This paper describes the methods of data collection and various characteristics of the study sample. Methods/Principal Findings: A standardised questionnaire covering musculoskeletal symptoms, disability and potential risk factors, was used to collect information from 47 samples of nurses, office workers, and other (mostly manual) workers in 18 countries from six continents. In addition, local investigators provided data on economic aspects of employment for each occupational group. Participation exceeded 80% in 33 of the 47 occupational groups, and after pre-specified exclusions, analysis was based on 12,426 subjects (92 to 1018 per occupational group). As expected, there was high usage of computer keyboards by office workers, while nurses had the highest prevalence of heavy manual lifting in all but one country. There was substantial heterogeneity between occupational groups in economic and psychosocial aspects of work; three-to fivefold variation in awareness of someone outside work with musculoskeletal pain; and more than ten-fold variation in the prevalence of adverse health beliefs about back and arm pain, and in awareness of terms such as "repetitive strain injury" (RSI). Conclusions/Significance: The large differences in psychosocial risk factors (including knowledge and beliefs about MSDs) between occupational groups should allow the study hypothesis to be addressed effectively.

Chances and risks of publication of quality data - the perspectives of Swiss physicians and nurses

Background The release of quality data from acute care hospitals to the general public is based on the aim to inform the public, to provide transparency and to foster quality-based competition among providers. Due to the expected mechanisms of action and possibly the adverse consequences of public quality comparison, it is a controversial topic. The perspective of physicians and nurses is of particular importance in this context. They are mainly responsible for the collection of quality-control data, and are directly confronted with the results of public comparison. The research focus of this qualitative study was to discover what the views and opinions of the Swiss physicians and nurses were regarding these issues. It was investigated as to how the two professional groups appraised the opportunities as well as the risks of the release of quality data in Switzerland. Methods A qualitative approach was chosen to answer the research question. For data collection, four focus groups were conducted with physicians and nurses who were employed in Swiss acute care hospitals. Qualitative content analysis was applied to the data. Results The results revealed that both occupational groups had a very critical and negative attitude regarding the recent developments. The perceived risks were dominating their view. In summary, their main concerns were: the reduction of complexity, the one-sided focus on measurable quality variables, risk selection, the threat of data manipulation and the abuse of published information by the media. An additional concern was that the impression is given that the complex construct of quality can be reduced to a few key figures, and it that it is constructed from a false message which then influences society and politics. This critical attitude is associated with the different value system and the professional self-concept that both physicians and nurses have, in comparison to the underlying principles of a market-based economy and the economic orientation of health care business. Conclusions The critical and negative attitude of Swiss physicians and nurses must, under all conditions, be heeded to and investigated regarding its impact on work motivation and identification with the profession. At the same time, the two professional groups are obligated to reflect upon their critical attitude and take a proactive role in the development of appropriate quality indicators for the publication of quality data in Switzerland.

Mortality from neurodegenerative disease and exposure to extremely low-frequency magnetic fields: 31 years of observations on Swiss railway employees

AIMS: The objective of the present study was to investigate the relationship between extremely low-frequency magnetic field (ELF-MF) exposure and mortality from several neurodegenerative conditions in Swiss railway employees. METHODS: We studied a cohort of 20,141 Swiss railway employees with 464,129 person-years of follow-up between 1972 and 2002. For each individual, cumulative exposure was calculated from on-site measurements and modelling of past exposure. We compared cause-specific mortality in highly exposed train drivers (mean exposure: 21 microT) with less exposed occupational groups (for example station masters: 1 microT). RESULTS: The hazard ratio for train drivers compared to station masters was 1.96 [95% confidence interval (CI) = 0.98-3.92] for senile dementia and 3.15 (95% CI = 0.90-11.04) for Alzheimer's disease. For every 10 microT years of cumulative exposure senile dementia mortality increased by 5.7% (95% CI = 1.3-10.4), Alzheimer's disease by 9.4% (95% CI = 2.7-16.4) and amyotrophic lateral sclerosis by 2.1% (95% CI = -6.8 to 11.7). There was no evidence for an increase in mortality from Parkinson's disease and multiple sclerosis. CONCLUSIONS: This study suggests a link between exposure to ELF-MF and Alzheimer's disease and indicates that ELF-MF might act in later stages of the disease process.

Leukaemia, brain tumours and exposure to extremely low frequency magnetic fields: cohort study of Swiss railway employees

AIMS: To investigate the relationship between extremely low frequency magnetic field (ELF-MF) exposure and mortality from leukaemia and brain tumour in a cohort of Swiss railway workers. METHODS: 20,141 Swiss railway employees with 464,129 person-years of follow-up between 1972 and 2002 were studied. Mortality rates for leukaemia and brain tumour of highly exposed train drivers (21 muT average annual exposure) were compared with medium and low exposed occupational groups (i.e. station masters with an average exposure of 1 muT). In addition, individual cumulative exposure was calculated from on-site measurements and modelling of past exposures. RESULTS: The hazard ratio (HR) for leukaemia mortality of train drivers was 1.43 (95% CI 0.74 to 2.77) compared with station masters. For myeloid leukaemia the HR of train drivers was 4.74 (95% CI 1.04 to 21.60) and for Hodgkin's disease 3.29 (95% CI 0.69 to 15.63). Lymphoid leukaemia, non-Hodgkin's disease and brain tumour mortality were not associated with magnetic field exposure. Concordant results were obtained from analyses based on individual cumulative exposure. CONCLUSIONS: Some evidence of an exposure-response association was found for myeloid leukaemia and Hodgkin's disease, but not for other haematopoietic and lymphatic malignancies and brain tumours.

Traditionen, Utopien, Dekonstruktionen - die Sozialstaatskonzepte des 'Ostblocks' (1945-1990)

The welfare state concepts in Eastern Europe under state socialism (1945-1990) were based on the conviction that only the state was responsible for solving all social problems. The 'bourgeois' manners of individual care were substituted by general measures in the field of labour- and family politics, as well as urban development. The experience showed however that this way of substitution was an illusion, because certain target groups were still in need of help (for example ill or handicapped children and adults, elderly people etc). Nevertheless, most of the Eastern European countries - with the exception of Yugoslavia - decided to abolish the existing forms of professional social work and the training for social workers. Instead, they invented 'surrogate structures' to manage the care for the 'needy': Various institutions and occupational groups (schools, hospitals and ambulances, employees groups etc.) took over the tasks of social workers and were trained to fulfil this as a kind of 'social practice'. Therefore, it is wrong to claim that social work was completely abolished under state socialism, But: as social work 'as such' did not exist any longer, it is more reasonable to speak of welfare state concepts, including social policy on one hand, and non- or paraprofessional social practice on the other. To characterize the effect of these welfare state concepts three parameter of interpretation seem to be useful: 'traditions', 'visions', and 'deconstructions' - embedded in a system of repression as well as incentives. Traditions: The huge 'social laboratory' that was installed was not a totally new one - it still carried on the heritage of the bygone: some bourgeois traces as well as elements out of the fascist heritage and -last but not least - the traditions of their own socialist movement. Visions: The socialist traditions included visions of social justice, the creation of a 'new mankind', a classless society, the end of exploitation and a peaceful living together of all people. Although the 'real existing socialism' has destroyed most of these visions, the power of these utopian ideas has outshined a lot of the every day’s misfortune and injustice for quite a long time. Deconstructions: The term of 'deconstruction' has a threefold meaning: the deconstruction of professional welfare, the deconstruction - in the sense of reinterpretation - of the socialist ideals such as social justice and social security, making an instrument of inclusion and exclusion out of it. And the deconstruction that is necessary to free the history of social work under state socialism from the prejudices and distorting practices, from both sides, the east and the west. In the contribution these three parameter of interpretation are applied on the following issues: The gaps in the 'overall system' of social security; working morale and education for work; mass organisations as an instrument of egalitarianism and general prevention; de-professionalisation by 'surrogating' social work; the 'transparent client'; church as refuge or 'state organ'; women’s politics as bio-politics.

Safety climate and its association with office type and team involvement in primary care

OBJECTIVE To assess differences in safety climate perceptions between occupational groups and types of office organization in primary care. METHODS Primary care physicians and nurses working in outpatient offices were surveyed about safety climate. Explorative factor analysis was performed to determine the factorial structure. Differences in mean climate scores between staff groups and types of office were tested. Logistic regression analysis was conducted to determine predictors for a 'favorable' safety climate. RESULTS 630 individuals returned the survey (response rate, 50%). Differences between occupational groups were observed in the means of the 'team-based error prevention'-scale (physician 4.0 vs. nurse 3.8, P < 0.001). Medical centers scored higher compared with single-handed offices and joint practices on the 'team-based error prevention'-scale (4.3 vs. 3.8 vs. 3.9, P < 0.001) but less favorable on the 'rules and risks'-scale (3.5 vs. 3.9 vs. 3.7, P < 0.001). Characteristics on the individual and office level predicted favorable 'team-based error prevention'-scores. Physicians (OR = 0.4, P = 0.01) and less experienced staff (OR 0.52, P = 0.04) were less likely to provide favorable scores. Individuals working at medical centers were more likely to provide positive scores compared with single-handed offices (OR 3.33, P = 0.001). The largest positive effect was associated with at least monthly team meetings (OR 6.2, P < 0.001) and participation in quality circles (OR 4.49, P < 0.001). CONCLUSIONS Results indicate that frequent quality circle participation and team meetings involving all team members are effective ways to strengthen safety climate in terms of team-based strategies and activities in error prevention.

Patientensicherheit in der Hausarztpraxis

Einleitung Aus der Schweizer Grundversorgung lagen bisher noch keine systematischen Daten zu kritischen Ereignissen und zum Sicherheitsklima vor. Aus diesem Grund wurde eine Befragung von Ärzten und Medizinischen Praxisassistentinnen (MPA) in Deutschschweizer Hausarztpraxen sowie ein Folgeprojekt spezifisch zur Telefon-Triage durchgeführt. Methoden Mit Hilfe eines standardisierten Fragebogens wurden Fachpersonen in Hausarztpraxen zu Sicherheitsrisiken und zum Sicherheitsklima in ihren Praxen befragt. Der Fragebogen enthielt neben Fragen zum Sicherheitsklima Beschreibungen von 23 kritischen Ereignissen in Hausarztpraxen, die bezüglich Häufigkeit des Auftretens in der Praxis in den vergangenen zwölf Monaten sowie der Schadensfolge beurteilt wurden, als das Ereignis zum letzten Mal in der Praxis aufgetreten ist. Zudem beantworteten Ärzte und MPA eine offene Frage, nach den für sie besonders relevanten Risiken für die Patientensicherheit in ihren Praxen. Im Folgeprojekt wurden Interviews und Gruppendiskussionen mit MPA und Ärzten geführt, um eine Prozessanalyse der Telefon-Triage durchzuführen und ein Hilfsmittel für Hausarztpraxen zur Stärkung einer sicheren Telefon-Triage zu entwickeln. Ergebnisse 630 Ärzte und MPA (50,2% Ärzte, 49,8% MPA) haben an der Studie teilgenommen. 30% der Ärzte und 17% der MPA gaben an, mindestens einen der untersuchten Ereignisse täglich oder wöchentlich in ihrer Praxis zu beobachten. Fehler bei der Dokumentation wurden am häufigsten beobachtet. Ereignisse, die sich aufgrund der Schadensfolge als besonders relevant erwiesen, waren Fehleinschätzungen bei Kontaktaufnahmen der Patienten mit der Praxis, Diagnosefehler, mangelnde Überwachung von Patienten nach therapeutischen Massnahmen und Fehler in Zusammenhang mit der Medikation. Die Medikation (28% der Nennungen), medizinische Verrichtungen in der Praxis (11%) und die Telefon-Triage (7%) wurden am häufigsten als die Risiken genannt, die die Studienteilnehmer in ihren Praxen gerne eliminieren würden. In Bezug auf das Sicherheitsklima erwiesen sich insbesondere Teamsitzungen und regelmässige Qualitätszirkel-Teilnahme als relevante Prädiktoren für die Dimension „Teambasierte Aktivitäten und Strategien zur Fehlerprävention“. Berufsgruppenunterschiede zwischen Ärzten und MPA konnten sowohl hinsichtlich der berichteten Sicherheitsrisiken, als auch beim Sicherheitsklima beobachtet werden. Fazit Die Ergebnisse der Studie legen die Telefon-Triage als bislang wenig beachteten jedoch sehr relevanten Sicherheitsbereich in der Grundversorgung dar. Um die Sicherheit der Telefon-Triage zu stärken, wurde ein Anschlussprojekt durchgeführt, aus dem heraus ein Leitfaden für Hausarztpraxen entwickelt wurde. Dieser Leitfaden soll Ärzte und MPA in einer gemeinsamen und kritischen Auseinandersetzung von Strukturen und Prozessen rund um die Telefon-Triage sowie der Entwicklung von Verbesserungsschritten unterstützen. Die systematisch beobachteten Berufsgruppenunterschiede sind ein wichtiger Hinweis dafür, dass das gesamte Praxisteam in die Analyse von Sicherheitsrisiken und die Entwicklung von Massnahmen einbezogen werden sollte. Nur so können Risiken umfassend erfasst und für alle Fachpersonen relevante und getragene Verbesserungen initiiert werden. Dieser Ansatz der Team-Involvierung bildet die Basis für den Praxisleitfaden zur Telefon-Triage.

Das Repertorium Academicum Germanicum (RAG). Ein digitales Forschungsvorhaben zur Geschichte der Gelehrten des alten Reiches (1250-1550)

This article aims at presenting an already existing research project. The Repertorium Academicum Germanicum (RAG) is supposed to be a "Who’s who" of the graduated and noble scholars of the late medieval Empire. It is designed to record biographical and social data of graduated theologians, jurists, physicians and Masters of Art as well as data of nobles from universities between 1250 and 1550. Furthermore, the project focuses on their examinations, networks, fields of activity in ecclesiastical and secular offices as well as their achievements and legacies (books, treatises, tombs etc). Right now, over 49.000 prosopographic entries are stored in the RAG database, partly available online (www.rag-online.org) and combined with digital maps (infographics), which already provide a basis for research in academic mobility determined by the top scholars of the time. In a next step, it should be possible to draw conclusions not only about personnel and knowledge transfer from university to society, its effects on political systems, daily life, the emergence of new occupational groups and professions, but also about cultural exchange within Europe.

Assessing homogeneity in workplace exposure under stationary and non-stationary scenarios

In most epidemiological studies, historical monitoring data are scant and must be pooled to identify occupational groups with homogeneous exposures. Homogeneity of exposure is generally assessed in a group of workers who share a common job title or work in a common area. While published results suggest that the degree of homogeneity varies widely across job groups, less is known whether such variation differs across industrial sectors, classes of contaminants, or in the methods used to group workers. Relying upon a compilation of results presented in the literature, patterns of homogeneity among nearly 500 occupational groups of workers were evaluated on the basis of type of industry and agent. Additionally, effects of the characteristics of the sampling strategy on estimated indicators of homogeneity of exposure were assessed. ^ Exposure profiles for occupational groups of workers have typically been assessed under the assumption of stationarity, i.e., the mean exposure level and variance of the distribution that describes the underlying population of exposures are constant over time. Yet, the literature has shown that occupational exposures have declined in the last decades. This renders traditional methods for the description of exposure profiles inadequate. Thus, work was needed to develop appropriate methods to assess homogeneity for groups of workers whose exposures have changed over time. A study was carried out applying mixed effects models with a term for temporal trend to appropriately describe exposure profiles of groups of workers in the nickel-producing industry over a 20-year period. Using a sub-set of groups of nickel-exposed workers, another study was conducted to develop and apply a framework to evaluate the assumption of stationarity of the variances in the presence of systematic changes in exposure levels over time. ^

Psychosocial factors and musculoskeletal symptoms in a vulnerable working population in Nicaragua

This research is a secondary data analysis of the CUPID-INCA Nicaragua study, a cross-sectional study comparing psychosocial and physical factors on musculoskeletal symptoms among nurses, office workers and maquiladoras in Nicaragua. There were three objectives for this thesis. (1) To describe the study population according to their socio-demographic, psychosocial (i.e. work organization and health beliefs) and physical factors. (2) To estimate the prevalence of musculoskeletal disorders (MSDs) in the study population (nurses, office workers and maquilas). (3) To analyze and compare the trends of association between psychosocial factors and MSDs to that of physical factors and MSDs in the study population. Trends of association between MSDs and psychosocial factors were also compared between nurses, office workers and maquilas. ^ Majority of the total study population were females, middle aged, non smokers and had been on the job for more than five years. Prevalence rates of low back pain and upper extremity pain were 28% and 37% respectively in nurses, 17% and 34% in office workers and 18% and 31% in maquilas. Workers' health belief was significantly associated with MSDs in all three occupational groups. Psychosocial factors were not consistently associated more with MSDs than physical factors. Maquilas had more psychosocial factors statistically significantly associated with musculoskeletal symptoms than nurses and office workers. ^ The findings of this research suggest that both psychosocial and physical risk factors play a role on the prevalence of musculoskeletal symptoms in the three working populations in Nicaragua. Future research in this area should explore further, the risk of developing MSDs from workers' exposure to psychosocial factors as well as physical factors.^

LUNG CANCER AMONG TEXAS MALE OIL REFINERY WORKERS, 1976 - 1980 (CASE-CONTROL STUDY)

The apparent excess in the rate of lung cancer among the population of Texas coastal counties has prompted this study. The main objective was to assess the risk of lung cancer among employees of oil refining industries. Data collected by UTSPH and NCI were used for this research. A non significant overall low risk of lung cancer was observed among workers ever employed in oil refining (COR = 0.84). A lower but not significant risk of lung cancer was detected among the same workers when classified by their usual industry of employment (COR = 0.77). An overall non significant crosstime decline in the risk of lung cancer was observed among most of the occupational groups within the oil refining industry, with the exception of professional/technical and clerical/sales occupations where a non significant crosstime increase in the risk was observed. ^
