Frequent Exposure (frequent + exposure)
Selected AbstractsOccupational exposure of Brazilian neonatal intensive care workers to latex antigensALLERGY, Issue 1 2004R. A. M. Lopes Background:, Frequent exposure to latex causes various reactions such as respiratory symptoms and anaphylactic shock. In these cases, proteins found in natural latex are responsible for the serious systemic antilatex-mediated immediate hypersensitive reactions. Methods:, Cross-sectional descriptive survey focusing on 96 Brazilian health care workers (HCW) in the neonatal intensive care unit at CAISM, State University of Campinas UNICAMP, Brazil. All subjects were interviewed, donated blood samples for the latex-specific immunoglobulin E measurement and underwent the skin prick test (SPT) with an antigen extracted from latex gloves. Results:, The prevalence of latex positive SPT was 8%. There were eight SPT positive and only one serologic test was in agreement with the SPT. Overall, there was evidence of an association between the latex SPT and reported eczema (P = 0.01); food allergy (P = 0.009) with pineapple (P = 0.01). Conclusions:, These results suggest that the identification of reactions of immediate hypersensitivity mediated by antilatex antibodies in HCW should be encouraged to prevent occupational exposure to latex products. [source] Race/Ethnic Differences in Effects of Family Instability on Adolescents' Risk BehaviorJOURNAL OF MARRIAGE AND FAMILY, Issue 2 2010Paula Fomby We used data from the National Longitudinal Study of Adolescent Health (N = 7,686) to determine whether racial and ethnic differences in socioeconomic stress and social protection explained group differences in the association between family structure instability and three risk behaviors for White, Black, and Mexican American adolescents: delinquent behavior, age at first nonmarital sex, and age at first nonmarital birth. The positive association between mothers' union transitions and each outcome for White adolescents was attenuated by social protection. The association of instability with age at first sex and first nonmarital birth was weaker for Black adolescents but not for Mexican American adolescents. The weaker association was explained by Black adolescents' more frequent exposure to socioeconomic stress in the context of union instability. [source] Work stress and physical assault of nursing aides in rural nursing homes with and without dementia special care unitsJOURNAL OF PSYCHIATRIC & MENTAL HEALTH NURSING, Issue 3 2005D. G. MORGAN phd rn Purpose:, This study compared nursing aides (NAs) employed in rural nursing homes with and without dementia special care units (SCUs) on (1) exposure to and distress from disruptive behaviours exhibited by residents, (2) job strain and (3) physical assault. Design and methods:, The data were drawn from a larger study conducted in Saskatchewan, Canada, in which all rural nursing homes of ,,100 beds that had an SCU were matched to same-sized rural facilities with no SCU. Nursing aides (n = 355) completed a mailed survey questionnaire. Results:, Nursing aides employed in nursing homes with an SCU reported significantly less frequent exposure to disruptive behaviours (including aggressive and aversive behaviours) than NAs in non-SCU facilities, less distress when these behaviours were directed toward them, less exposure to aggressive behaviour during caregiving, lower job demands and lower job strain. There was a trend toward increased risk of being assaulted in the last year associated with being in a non-SCU facility. Having a permanent position, increased job strain, and feeling inadequately prepared for dementia care were significantly associated with higher risk of being assaulted. In the SCU facilities, NAs who worked more time on the SCU reported more assaults but less distress from disruptive behaviour, lower psychological job demands, lower job strain and greater work autonomy. Implications:, Providing more dementia care training and reducing job demands and job strain may help to reduce work-related stress and physical assault of nursing aides employed in nursing homes. [source] Safety of pyrethroid-treated mosquito netsMEDICAL AND VETERINARY ENTOMOLOGY, Issue 1 2000M. Zaim Summary The use of insecticide treated nets (ITNs) for personal protection against malaria vector Anopheles mosquitoes (Diptera: Culicidae) has become popular during the past decade. With the precautions outlined in this paper, field use of pyrethroids , at concentrations recommended for treatment of mosquito nets , poses little or no hazard to people treating the nets or to users of the treated nets. With frequent exposure to low concentrations of pyrethroids, the risk of toxicity of any kind is remote. Pyrethroids entering the systemic circulation are rapidly metabolized to much less toxic metabolites. Toxicologically, pyrethroids have a useful characteristic , the production of skin paraesthesia , which gives an early indication of exposure. This reversible symptom of exposure is due to transient stimulation of peripheral sensory nerves and not a toxic effect. In the retail market, for home use, the provision of proper packaging and labelling, with clear instructions on safe and effective use of the product are most important. Because many domestic users of pyrethroid ,home treatment kits' for ITNs may not be fully literate, it is essential that ,instructions for use' should be portrayed via pictograms with supporting text in appropriate local language(s). [source] IgE sensitization, respiratory allergy symptoms, and heritability independently increase the risk of otitis media with effusionALLERGY, Issue 3 2006F. M. Chantzi Background and aims:, Epidemiological evidence examining the role of atopy and/or allergy in the pathogenesis of otitis media with effusion (OME) is inconclusive. The aim of this study was to assess any increased risk for OME attributable to allergy-related factors, in a well-characterized population using a case-control design and multivariate analysis. Subjects and methods:, Eighty-eight 1,7-year-old children with OME, diagnosed by clinical and tympanometric evaluation and 80 matched controls were enrolled. A standardized questionnaire was completed, in order to assess factors related to OME and allergy-related symptoms and diagnoses using strict clinical definitions. Specific IgE was measured by skin-prick tests and/or CAP-FEIA. Results:, The patient and control groups were well matched. Factors conferring increased risk for OME in the univariate analysis included IgE sensitization, dyspnea, wheezing, asthma, paroxysmal sneezing, rhinitis, eczema, ,any allergic disease,' family history of otitis media, and family history of allergy. After multivariate analysis IgE sensitization, wheezing, nasal obstruction, family history of otitis, and child-care attendance remained as independent risk factors for development of OME. Conclusion:, IgE sensitization and respiratory allergy symptoms are independent risk factors for the development of OME, suggesting that both immunological and mechanical pathways may contribute to the development of the disease. Otitis heritability provides additional risk, as well as frequent exposure to viral upper respiratory tract infections in children attending daycare. Treatment and/or prevention of OME using anti-allergic medications should be further examined. [source] Rural-urban differences in generation of Chinese and Western exemplary persons: The case of ChinaASIAN JOURNAL OF SOCIAL PSYCHOLOGY, Issue 1 2010Xia Chen Chinese adolescents in urban cities (Beijing, Chengdu) and rural towns (Wei Shan Zhuang, Zheng Xing) generated Chinese and Western exemplary persons and rated the values these exemplary persons represent. The results showed that the tendency to differentiate Chinese culture from Western culture was greater among urban (vs rural) Chinese. Specifically, only urban Chinese consistently attributed Chinese moral values (more than other types of values) to self-generated Chinese exemplary persons and Western moral values (more than other types of values) to self-generated Western exemplary persons. Because urban Chinese have more frequent exposure to foreign cultures, our results suggest that frequent exposure to foreign cultures can lead to enhanced perceptions of cultural differences. [source] Self-reported water and drowning risk exposure at surf beachesAUSTRALIAN AND NEW ZEALAND JOURNAL OF PUBLIC HEALTH, Issue 2 2009Damian Morgan Abstract Objective: To document patterns of water exposure at surf beaches by gender and identify factors that predict bather confidence to return to shore if caught in a rip current. Method: Recreational surf beach bathers (N=406) provided self-completed data on water exposure patterns, surf activity behaviours and potential drowning risk and protective factors. Results: Relative to females, males visited surf beaches more frequently, expected to spend longer in the water and in deeper water, and more often bathed after using alcohol (p<0.05). Confidence to return to shore if caught in a rip current was predicted by confidence to identify a rip current, self-rated swimming ability, gender, times visited any beach, and age in a standard linear regression model (adjusted R2=0.68). Conclusion: The study supports explanations that high male drowning rates result from more frequent exposure to water than females at high situational risk levels. Implications: Controlled studies are required to determine the role in drowning of overconfidence, swimming ability, surf experience, floatation devices and response to sea conditions. [source] |
