Violence, Burnout and Minor Psychiatric Disorders in Hospital Work

OBJECTIVE Identifying the violence suffered by the health team workers and their association with Burnout and minor psychiatric disorders. METHODS Cross-sectional study with 269 health team professionals of a public hospital in southern Brazil. Data were collected through the use of the Survey Questionnaire: Workplace Violence in the Health Sector, Maslach Inventory Burnout and Self-Report Questionnaire. RESULTS Workplace violence struck 63.2% of workers, prevailing mostly in women (p = 0.001), among nursing auxiliaries/technicians (p=0.014) and was associated with minor psychiatric disorders (p<0.05), as exposure to different forms of violence increased the chances of these disorders by 60% (CI 95%: 1.2-2.1). The three Burnout dimensions were also associated to violence at work (p<0.05). CONCLUSION Health workers experience violence in the workplace and this exposure is associated with Burnout symptoms and minor psychiatric disorders.

The new culture of electronic publishing

Local conditions in the past often limited opportunities for scholarly exchange. But now these limits are gone and the global workplace has replaced them. It is important to react to these changes. Every academic department must now adopt new methods and rethink processes. Another is the intense national and international debate about open access to scholarly knowledge. The Open Access Initiative shows that a change is taking place in the communication process. This change is also important for service departments within research institutions. Libraries, computer centers and related units have to ask themselves how to react appropriately to the new conditions. What services must be changed or redeveloped, and in what quality and quantity should they be offered? This article focuses on changes in the scholarly publication process. It describes both technological changes and the changes needed in people's attitudes.

Amostragem passiva de poluentes atmosféricos: aplicação ao SO2

The passive sampling technique has been widely used for many years in the measurement of personal exposure to pollutantes in the workplace. In recent years the technique has been used too for measurements in ambient air. In the specific case of SO2 a variety of passive samplers have been described in the literature. The great number are diffusive samplers and some few are permeation samplers. They are basically of two types: badge and tube-type. However there are more than 10 variations in relation to the sampler dimensions, diffusion barriers and pollutant sorption medium. The technique trend to be very used in the near future with samplers able to reach very low detection limits, proposing a viable option for monitoring specific species at urban, regional and global scales.

Determinação de manganês em material particulado atmosférico de ambientes de trabalho utilizando eletrodo de diamante dopado com boro e voltametria de onda quadrada com redissolução catódica

A boron-doped diamond electrode is used for determination of Mn(II) in atmospheric particulate matter by square wave cathodic stripping voltammetry. The analytical curve was linear for Mn(II) concentrations between 5.0 and 37.5 µg L-1, with quantification limit of 3.6 µg L-1. The precision was evaluated by the relative standard deviation, with values between 5.1% and 9.3%. The electrode is free of adsorption, minimizing memory effects. Samples collected in the workplace atmosphere of a foundry had Mn(II) concentrations between 0.4 and 4 µg m-3. No significant differences were observed between the proposed method and inductively coupled plasma optical emission spectroscopy.

Construção de amostrador passivo de baixo custo para determinação de dióxido de nitrogênio

A new passive sampling system for monitoring NO2 in air has been developed to measure gas concentrations in indoor and outdoor air. The sampler is inexpensive, and easy to construct and operate. Nitrogen dioxide forms a derivative after reaction with a filter coated with triethanolamine and ethyleneglycol. The nitrogen dioxide derivative is extracted from the filter, and the concentration is determined by colorimetry. To test the sampler for measuring ambient level nitrogen dioxide, measurements were carried out inside homes and in a range of workplace environments.

ADAPTAÇÃO DA METODOLOGIA DE ANÁLISE DE METEMOGLOBINA COMO BIOMARCADOR DE EFEITO DA EXPOSIÇÃO AO AGROTÓXICO DIFLUBENZURON

This work aimed to adapt the analysis of methemoglobin recommended by Evelyn - Malloy (visible spectrophotometry), in order to facilitate its application in the field, or to analysis in clinical laboratory, of existing sites of diflubenzuron application. The parameters changed included: centrifuge rotation speed; time between the collection of biological sample and analysis, and storage temperature of the samples; and the volume of reagents. The comparison of the rotation speed (rpm) of the reference methodology with the rpm of a "clinical centrifuge" did not reveal a statistically significant difference in the levels of methemoglobin. The time between the collection of biological sample and analysis was extended for a period of up to 48 hours for both conservation by refrigeration and ambient temperature, producing no statistically significant difference when compared to the standard duration of 2 hours. Regarding the reagents, the reference methodology already uses the volume necessary to ensure complete reaction, whereas a wider range from the recommended volume to a 5-fold reduction in comparison to the reference methodology could be used. It was concluded that the proposed changes to the methodology for adapting the analysis are applicable to studies of field / workplace exposure and ensure the reliability of results. The adapted methodology was inter-laboratory validated and the parameters changed can be selected according to the requirements of the laboratory at which the methemoglobin is to be measured.
