Organizational Factors and Office Workers’ Health After the World Trade Center Terrorist Attacks: Long-Term Physical Symptoms, Psychological Distress, and Work Productivity
No full textObjective: To assess if organizational factors are predictors of workers' health and productivity after the World Trade Center attacks.Methods: We conducted a survey of 750 workers and compared those who had direct exposures to the World Trade Center attacks (south of Canal Street workers; primary victims) with those less directly exposed (north of Canal Street workers; other victims and non-victims).Results: South of Canal Street workers reported headache more frequently than north of Canal Street workers did (P = 0.0202). Primary victims reported headache and cough more frequently than did other victims and non-victims (P = 0.0086 and 0.0043, respectively). Defensive organizational culture was an independent predictor of cough and job stress, and job stress was an independent predictor of on-the-job productivity losses.Conclusion: Organizational variables may modify health and productivity outcomes after a large-scale traumatic event in the workplace.This research was supported in part by the Centers for Disease Control and Prevention, National Institute for Occupational Safety and Health (NIOSH) Grant 5 R21 OH007713-02, and the NIEHS sponsored UMDNJ Center for Environmental Exposures and Disease, Grant NIEHS P30ES005022.This is a non-final version of an article published in final form in Journal of Occupational and Environmental Medicine (50(2):112-25, 2008 Feb) a publication of Lippincott, Williams & Wilkins.

Knowledge, Attitude, and Practice toward Clostridium Botulinum Outbreak in Home-Canned Bamboo Shoots at Pakaluang Subdistrict, Ban Luang District, Nan Province, Thailand
No full textThis study aims to assess the level of knowledge, attitude, and practice (KAP) toward Clostridium botulinum outbreak in home-canned bamboo shoots at Pakalung SubDistrict, Ban Luang District, Nan Province, Thailand. A cross-sectional approach was conducted to assess KAP using a structured questionnaire. A total of 280 people, randomly selected responded by face to face interview. The results indicated that the knowledge and attitude of the participants were moderate and neutral (57.9 % and 51.8 %, respectively). The prevalence of good practice level was 89.6 %. Furthermore, the knowledge was significantly associated with social-demographic characteristics (Chi-square, p<0.05) i.e. education level (p<0.001), occupation (p<0.029), monthly incomes (p<0.001). The attitude was associated with age group (p<0.001), education level (p<0.002), monthly incomes (p<0.001) and monthly incomes (p<0.001) are associated with practice level. The information gained would be utilized for health promotion and use of appropriate tools to increase more knowledge, and changing wrong beliefs concerning food habits and changing some people’s practices that might increase risk related to C. botulinum foodborne.Peer reviewed
Knowledge, Attitude, and Practice (KAP) of Using Personal Protective Equipment (PPE) for Chilli-Growing Farmers in Huarua Sub-district, Mueang District, Ubonrachathani Province, Thailand
No full textPesticide use in Thailand has increased significant, raising concerns about potentially adverse effects on human health and environment, in particular, as a number of pesticide products have been heavily used on chilli farms. The objectives of this study were: (1) to assess the knowledge, attitudes, and practices on using personal protective equipment (PPE) of chilli-growing farmers to protect themselves from pesticides, (2) to evaluate the knowledge, attitudes, and practices associated with pesticide use and exposure in the chilli-growing farmers, and (3) to provide recommendations and guidelines to reduce the exposure to pesticides among farmers in Huarua Sub-District, Mueang District, Ubonrachathani Province, Thailand. A standardized questionnaire was completed through face to face interviews with 330 chilli-growing farmers. The results showed that 53% of the participants were male and 39.6% and ages ranging between 31-40 years. 71.2 % had received primary school education and most of them applied pesticides by themselves. Almost 89.4% of respondents acknowledged that they ought to wear mask, boots, and cloth while spraying. Furthermore, 83.3% knew that pesticides can pass through their body in 3 ways; ingestion, dermal contact, and inhalation. In addition, 45.5% of respondents knew that spraying should be done in the windward direction and that they should use PPE. Many of the respondents checked their equipment before using them and wore clothing while spraying. Nevertheless, 77.2 % of chilli-growing farmers had low level of knowledge, 54.5 % of the farmers were not concerned about pesticide use or exposure, and 85.0 % of farmers demonstrated a fair level of actual usage. The associations between knowledge and attitude, knowledge and practice, and attitude and practice demonstrated statistical significance with low positive correlation (0.216, 0.285, and 0.305 respectively). The results suggested that government authorities and communities should be provided with the appropriate recommendations, strategies and guidelines to prevent adverse health effects regarding to pesticide exposure of farmers in this area.Peer reviewed
Assessing and Improving Bioterrorism Preparedness Among First Responders: A Pilot Study
No full textFollowing the September 11 terrorist attacks, the vulnerability of the United States became apparent. It also became evident that there was a need for respiratory protection. The purpose of this study was to determine the prior knowledge and perceptions of emergency medical technicians with respect to bioterrorism and to enhance their current knowledge to better prepare them for possible future events. The study was also designed to create a certified pool of trainers who would be capable of fit-testing all squad members with N-100 respirators. Representatives were recruited from each of the Hunterdon County, New Jersey, rescue squads. Participants attended a train-the-trainer session. Before the session and after, they were tested on knowledge and perceptions about relevant bioterrorism issues and were given an educational presentation on bioterrorism, threatening agents, respiratory health, and proper protection, along with being introduced to the fit-test steps for N-100 respirator masks. The response rate for the training was 94 percent. The authors measured and compared responses on the pre-test and the post-test with respect to knowledge, behaviors, and perceptions, and the results indicated a change following the training. The study thus provided evidence that the train-the-trainer program is an effective method of providing public health preparedness training to members of community organizations and agencies.Reprinted with permission from the Journal of Environmental Health, a publication of the National Environmental Health Association, www.neha.org.Supported by NIEHS Grants ES07148 and ES05022 and the Environmental and Occupational Health Sciences Institute.Peer reviewe

Residents' perspectives on forest health issues and management practices in Mount Robson Provincial Park.
No full textBritish Columbia and in particular the Central Interior region have a long history of infestation by mountain pine beetle (Dendroctonus ponderosae). However, current levels of mountain pine beetles have reached epidemic proportions in part due to the changing weather conditions and forest management practices. This current epidemic has resulted in changed forest conditions that make the forests more susceptible to fire and renewed beetle attacks. The epidemic is of particular concern for parks and protected areas due to the long history of fire suppression and inactive management. In the Robson Valley, community members find themselves immersed in issues regarding forest health and mountain pine beetle management and the corresponding effects on amenity, property, and ecological values without sufficient information from reliable and trusted sources. The rich amenity values of the Robson Valley manifest themselves in active and vocal community members thus recent strategies for active management within Mount Robson Provincial Park have met with some resistance. Limited communication between BC Ministry of Environment and local residents regarding active management strategies has only served to amplify this opposition. A survey was conducted with residents of Valemount and McBride to explore their perceptions of forest health and management practices in the Robson Valley. Results show that residents overwhelmingly want to be involved in the planning process for active management in Mount Robson Provincial Park. Resident's agree with active management strategies for a variety of management rationale, however they do not agree with all forms of active management. Improved communication strategies could help agencies such as BC Ministry of Environment gain support for more controversial management actions.The original print copy of this thesis may be available here: http://wizard.unbc.ca/record=b163702
Estratégias ambientais como alternativas para a prevenção de sintomas de ansiedade e depressão em um modelo experimental da doença de Parkinson em ratos
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências Biológicas, Programa de Pós-Graduação em Neurociências, Florianópolis, 2011A doença de Parkinson (DP) é uma doença multifatorial que se caracteriza pela degeneração progressiva de neurônios dopaminérgicas da substância negra parte compacta (SNpc). Apesar de ser reconhecido como um distúrbio do movimento, diversos sintomas psiquiátricos (como transtornos de ansiedade e depressão) são frequentemente observados em estágios iniciais da DP. Evidências da literatura indicam que toxinas e manipulações ambientais podem alterar o curso e a prevalência da DP. Este trabalho teve como objetivo avaliar o efeito de duas formas de manipulação da complexidade ambiental sobre comportamentos motores e emocionais em um modelo animal da DP induzido pela administração intranasal (i.n.) da toxina 1-metil-4-fenil- 1,2,3,6-tetrahidropiridina (MPTP). Foram utilizados ratos Wistar machos, que permaneceram continuamente em um ambiente enriquecido - experimento 1- ou foram expostos a sessões intermitentes em um ambiente complexo - experimento 2 - desde o desmame (21 dias de vida) até atingirem a idade adulta. Após atingirem a idade adulta (10 semanas), os animais receberam a infusão i.n. de MPTP (0,1 mg/narina), sendo em seguida avaliados até 7 dias nos testes do campo aberto, labirinto em cruz elevado (LCE) e nado forçado. Não foram observadas alterações locomotoras significativas em nenhum dos grupos avaliados no campo aberto. No experimento 1, os animais que receberam MPTP e/ou que permaneceram de maneira contínua no ambiente enriquecido apresentaram comportamentos do tipo ansiogênico e depressivo. Por outro lado, no experimento 2, as sessões intermitentes de enriquecimento preveniram a ocorrência de comportamentos do tipo ansiogênico e depressivo induzidos pela administração i.n. de MPTP . Em conjunto, os resultados do presente estudo demonstram que diferentes protocolos de manipulação ambiental podem influenciar de maneiras distintas os sintomas de ansiedade e depressão em ratos submetidos ao modelo da administração i.n. de MPTP. Assim, manipulações ambientais podem apresentar significativas implicações para a prevenção e o tratamento adjuvante da DP, o que representa um interessante campo de investigação.Parkinson1s disease (PD) is a multifactorial disorder characterized by the progressive degeneration of the dopaminergic neurons of the substantia nigra pars compacta (SNpc). Although PD is classically considered to be a motor function disease, diverse psychiatric symptoms (such as anxiety and depression) are frequently observed during the early pre-motor stages of PD. Moreover, there is increasing evidence suggesting that both environmental toxins and manipulations may interfere with the development of PD. Therefore, the aim of the current study was to investigate the effects of two distinct protocols of environmental manipulation in the motor and emotional behaviors of rats infused intranasally with 1-methyl-4-phenyl-1,2,3,6- tetrahydropyridine (MPTP), an experimental model of PD developed in our laboratory. Male Wistar rats were reared continuously in an enriched environment (EE) - experiment 1 - or were exposed to intermittent sessions in a complex environment - experiment 2 - from the post-natal day 21 until 10 weeks of age (adulthood) when they received a single bilateral intranasal (i.n.) infusion of MPTP (0.1 mg/nostril) and them were evaluated in the open field, elevated plus-maze (EPM) and forced swim test (FST) during a period of 7 days. The results showed no significant locomotor alterations in any group evaluated in the open field. In the experiment 1, the animals that received MPTP and/or were reared continuously in the EE displayed increased anxiety- and depressive-like behaviors. In the experiment 2, the exposure to intermittent EE sessions prevented the increase in the anxiety- and depressive-like behaviors induced by i.n. MPTP administration. Altogether, the findings of the present study indicate that differences in the enviromental manipulations may interfe in distinct ways the anxietyand depressive-like behaviors of rats submitted to the i.n. MPTP model of PD. Therefore, environmental manipulations may have significant implications for the prevention and adjunctive treatment of PD, which represents an interesting field for further studies
