- ? A pilot study of catheterized women was designed to investigate their perceptions of pain and discomfort during the procedure.
- ? The study aimed to test the feasibility of conducting a larger randomized controlled trial.
- ? Problems were encountered during the execution of the study, due to the need to conform to established principles in clinical research.
- ? Restrictions on access to patients impinged upon the opportunity to ‘cast the net wide’ in order to generate meaningful data.

Summary
- ? The objective of this study was to describe the variation in provision of health checks and health-promotion clinics operating under the regulations of the 1990 Contract for general practice in the UK.
- ? Eighteen group practices in three Family Health Service Authority (FHSA) areas of England (two in the South West Thames region and one in the Yorkshire region) were selected for the study. The nurses, largely responsible for the implementation of the health checks at these practices, were interviewed using semi-structured interview schedules. They were asked about age-groups targeted, means of recruiting patients for clinics, duration of clinic appointments, and procedures carried out in clinics.
- ? All practices offered health checks, and 55% had started doing so before introduction of the 1990 Contract. Recruitment for health checks took place in a number of ways: self-referral (83% of practices); opportunistically in those with coronary heart disease risk factors (78%); opportunistically during attendance for cervical smears (62%); screening in at least one patient group (78%). Blood pressure, height, weight, urinalysis and life-style advice were included by all practices. Stress management and quit smoking strategies were offered only by a minority of practices. Duration of first health-check appointment ranged between 15 and 30 minutes.
- ? The basic content of health checks, and life-style advice given appeared consistent between the widely varying practices. However, the resources available for intervention and follow up showed more variation.

Context
In keeping with the Patient Protection and Affordable Care Act, Congress revised the law related to workplace wellness programs. In June 2013, the Departments of Treasury, Labor, and Health and Human Services passed the final regulations, updating their 2006 regulatory framework. Participatory programs that reward the completion of a health risk assessment are now the most common type of wellness program in the United States. However, legal and ethical concerns emerge when employers utilize incentives that raise questions about the voluntariness of such programs. At issue is that under the Americans with Disabilities Act (ADA) of 1990, employers cannot require health-related inquiries and exams.Methods
To analyze the current interpretation of the ADA, I conducted research on both LexisNexis and federal agency websites. The resulting article evaluates the differences in the language of Congress''s enabling legislation and the federal departments’ regulations and how they may conflict with the ADA. It also reviews the federal government''s authority to address both the legal conflict and ethical concerns related to nonvoluntary participatory programs.Findings
Employers’ practices and the federal departments’ regulations conflict with the current interpretation of the ADA by permitting employers to penalize employees who do not complete a health risk assessment. The departments’ regulations may be interpreted as conflicting with Congress''s legislation, which mentions penalties only for health-contingent wellness programs. Furthermore, the regulatory protections for employees applicable to health-contingent wellness programs do not apply to participatory programs.Conclusions
Either Congress or the federal agencies should address the conflict among employers’ practices, the wellness regulations, and the ADA and also consider additional protections for employees. Employers can avoid ethical and legal complications by offering voluntary programs with positive incentives. 相似文献16.
In this article we investigate fathers influence on the dieting behavior of their adolescent daughters. Fifty father-daughter dyads (N = 100) participated. The girls completed a questionnaire concerning their beliefs and behaviors with respect to dieting, their body satisfaction, and their perception of the advantages of being thinner. Fathers were surveyed in order to ascertain their perceptions of the advantages of slimness for adolescent girls and their beliefs regarding the importance of physical appearance and weight control in females of all ages. Associations were found between fathers attitudes to physical attractiveness in females, their perceptions of the impact of being slimmer for adolescent girls, and their daughters dieting behavior. Fathers who believed strongly in the importance of attractiveness and careful control of food intake by females were significantly more likely to have daughters who induced vomiting to lose weight. Fathers play an influential role in determining the dieting behavior of their adolescent daughters. 相似文献

Abstract: Cutaneous alternariosis is a rare infection typically observed only in immunocompromised adults, but we report here that the infection can occur in apparently healthy adolescents. We saw a clinically healthy adolescent boy who presented with cutaneous alternariosis 6 weeks after suffering a laceration to his right ankle. Treatment with itraconazole resulted in significant improvement after 1 month. 相似文献
