Abstract

Health science students, along with the health professionals they hope to become, are at increased risk for certain occupational injuries and illnesses. One of these risks is occupational exposure to blood-borne pathogens, such as human immunodeficiency virus (HIV) and hepatitis, which may result in severe illnesses or even death. Two case studies demonstrate postexposure care of exposed individuals at the University of Texas Medical Branch Student Health Services before and after policy changes and prevention strategies were strengthened in response to exposure incidents.  相似文献

Summary

With 7% of the population of India being elderly, two-thirds of whom live in villages and nearly a half of them in poor conditions, the care of the elderly is a difficult problem to be tackled. The dwindling of the joint family, the rise of dual-career families, a possible shift in filial piety values, the increasing life expectancy with greater chances of a prolonged old age characterized by poverty, degeneration, more empty-nest years, and dependency, have all added to the seriousness of the problem and made the elderly more susceptible than ever to abusive treatment. This paper examines these issues as well as the issue of elder abuse in light of available data and suggests some strategies to meet the problem. Also discussed are the problems, stresses, and strains of caregivers of the elderly. A greater role is envisaged for Non-Governmental Organizations (NGOs) than the state in the care of the elderly, particularly in providing support services to family caregivers.  相似文献

Job stress can lead to various system dysfunctions, but until now no reliable biomarkers for its assessment have been identified. Allostatic load (AL) is an index that enables the cumulative effect on the body of chronic stress to be assessed, and is derived from a set of relevant biological measures. In this study, a 13-parameter index (building on the original 10-item index) was used to examine the relationship between job strain and AL. Participants were 1219 healthy Chinese employees. Job strain was measured using the Job Content Questionnaire, and AL was assessed by various possible stress responses, including blood pressure, cholesterol, indicators of glucose metabolism, and hormone and inflammation markers. AL in the high job strain group differed sharply from that in the low job strain group. The AL score was positively associated with age and educational level. Several individual parameters also differed between the two groups. Men scored significantly higher on AL and cardiovascular and metabolic health outcomes, whereas for women the associations appeared in the biological indicators. Analyses indicated that decision latitude (DL) and job demands were significantly related to AL. Job demands correlated significantly with the primary biological indicators and DL with the secondary health outcomes. In conclusion, this study provides evidence of the value of measuring allostatic load in assessing the chronic effects of job stress.  相似文献

该研究通过对14所普通高中、15所职业中学704名教师的问卷调查,将普通高中、职业中学教师的教学效能感和工作压力对教师职业枯竭的预测作用进行了比较,结果表明:第一,工作压力对普通高中和职业中学教师的职业枯竭具有显著的预测作用,但是存在差异;第二,教学效能对普通高中和职业中学教师的职业枯竭都具有显著的预测作用,但是存在差异;第三,通过对工作压力和教学效能的联合考察,能够更好地预测普通高中和职业中学教师的职业枯竭。  相似文献

震后早期心理辅导探讨   总被引:4,自引:1,他引:3  
5·12汶川大地震后,心理援助的重要性受到前所未有的关注.震后人们会出现不同程度的心理应激反应,相当比例的人会出现心理应激障碍.针对这些问题应进行适当的早期心理辅导.早期心理辅导应以创伤后危机干预为思路,以缓解应激障碍相关症状、预防创伤后危机障碍的发生为主要目标,采取心理急救、严重事件应激晤谈、认知行为疗法等方法进行治疗.另外,从这些方法中可归纳出共同的、可用于早期心理辅导的原则:支持性原则、正常化原则、重视社会支持原则、个性化原则等.  相似文献

Suffering at work has become a major social phenomena. This situation has many causes: high performance enhancement, urgency seen as an obligation, pressure for results, but also fear, and the soaring of ‘the battle for places’ (la lutte des places). The psychopathological consequences of pressure at work are now well known: breakdowns, professional exhaustion, work addiction, burnout, harassment. Stress has become an ordinary tool for management. Employees cannot find a meaning to this context, nor can they identify the causes of their ill being or the reasons for the violence they endure. They confront an opaque and paradoxical power. Looking for solutions to the contradictions to which management has given rise without resolving, they become responsible for those difficulties and guilty of their own suffering. These are ‘innocent violences’ in so far as they are justified by an indisputable system of management.  相似文献
