The diagnostic utility of cerebrospinal fluid creatine kinase activity in the horse.

We evaluated creatine kinase (CK) activity in the cerebrospinal fluid (CSF) of 128 horses with various neurological disorders. No association was found between CSF CK activity and CSF red blood cell count, CSF nucleated cell count, CSF total protein concentration, or serum CK activity. The sensitivity and specificity of CSF CK activity as a diagnostic test for protozoal myelitis in horses (61% and 56%, respectively) was higher than for cervical stenotic myelopathy, degenerative myelopathy, or motor neuron disease, but was considered to be inadequate to be of use diagnostically. Contamination of CSF with whole blood, hemolyzed red blood cells, or serum did not substantially contribute to increases in CSF CK activity. Addition of epidural fat or dura to CSF significantly increased CSF CK activity in all cases. We suggest that the use of CSF CK activity as a diagnostic indicator of neurological disease in the horse in unreliable, and that CSF CK activity may be falsely increased by contamination of CSF with epidural fat or dura during CSF collection.

Teaching assertive communication skills to adolescents with diabetes: evaluation of a camp curriculum.

Diabetes management requires consistently implementing adherence behaviors in a variety of settings. For some adolescents, consistency may be difficult due to problems in communication and assertiveness. The purpose of the present study was to evaluate the impact of a camp curriculum to teach assertive communication skills to adolescents with diabetes. The curriculum included didactic information, sharing of personal experiences, and role playing. Results showed a significant increase in adolescents' perceptions of their assertiveness from before to after the camp experience, an increase that was still apparent at a 3-month follow-up. No changes were reported in parental perceptions of their adolescents' degree of openness in communicating or in communication problems. In contrast, adolescents reported a significant decrease in their degree of openness in communicating with fathers, with a similar trend for mothers. These results suggest that the curriculum was successful in meeting the primary goal of enhancing the adolescents' assertive communication skills but had a questionable impact on their general communications with parents.

Facilitators and barriers to cervical cancer screening among Chinese Canadian women.

BACKGROUND: Chinese Canadian women have higher cervical cancer incidence, and lower Pap testing, rates than the general Canadian population. Predisposing, enabling and reinforcing factors associated with ever having a Pap test, and having a recent Pap test within the last 2 years, were assessed in Chinese women in British Columbia using the PRECEDE-PROCEED model. METHOD: Chinese women (n=512) between the ages of 20 and 79 years and residing in Greater Vancouver were interviewed about Pap testing, health care, traditional health beliefs, acculturation and sociodemographic characteristics. Two analyses were done, comparing women who had ever and never had a Pap test, and comparing women who had and had not received a recent Pap test. Focus groups and qualitative interviews ensured cultural sensitivity in the survey questionnaire. RESULTS: Seventy-six percent reported ever having a Pap test and 57% reported having a Pap test within the last 2 years. Traditional health beliefs were not associated with ever or recent Pap testing. However, belief that Pap testing prevented cancer and general knowledge about the Pap test were associated with screening. Concern about pain/discomfort with the test, availability of time, culturally sensitive health care services and recommendation for Pap testing by a physician were also associated with screening. Factors differed for ever, and recently, having a Pap test. INTERPRETATION: Pap testing is less common among Chinese Canadian women. Continuing education about Pap testing is recommended for physicians serving underscreened Chinese women. Culturally and linguistically appropriate educational materials are needed for the Chinese community.

Use of educational resources for cardiovascular risk reduction in the Stanford Five-City Project.

To investigate the extent to which individuals use health education resources for cardiovascular risk reduction, we conducted a cross-sectional survey of 2,234 adults 18-74 years of age in four northern California cities. The purposes of the study were to (1) assess the use of 10 cardiovascular disease (CVD) intervention materials and programs, (2) compare use rates between the treatment and control communities of the Stanford Five-City Project, and (3) examine variation in use by type of intervention, risk factor, and sociodemographic status. The community level analyses indicate that up to one-third of adults had used interventions to modify CVD risk factors during a one-year period, and that communities with comprehensive risk reduction programs had higher rates of use, particularly for printed education materials. The subgroup analyses indicate substantial variability in use depending on sociodemographic status, with those at highest risk (men, older adults, and low socioeconomic groups) reporting the lowest use of CVD intervention materials and programs.

Infectious bursal disease virus variant from commercial Leghorn pullets.

An infectious bursal disease virus (IBDV) was isolated from 39-to-43-day-old commercial leghorn pullets suspected of having infectious bursal disease (IBD). These chickens had been vaccinated with a commercial live IBDV vaccine at 28 and 35 days of age. An isolate designated IN was recovered using specific-pathogen-free (SPF) chickens and the BGM-70 established cell line. Experimental studies using SPF chickens vaccinated with either inactivated vaccines made from the vaccine strain used in the problem flock or a standard-type vaccine indicated no protection against the IN isolate. However, two variants and another standard-type vaccine induced protection against the IN isolate. Cross-neutralization tests indicated that the IN isolate differed antigenically from commercial vaccine strains and was related to the variant IBDV strains recently isolated from broilers. To our knowledge, this is the first report of a variant IBDV recovered from commercial layer chickens in the United States.

The experience and satisfaction of women attending breast cancer screening.

PURPOSE/OBJECTIVES: To determine women's satisfaction and experience with breast cancer screening and associated factors. DESIGN: Exploratory, descriptive design. SETTING: One center of the Ontario Breast Screening Program, a province-wide breast cancer screening program. SAMPLE: Nonprobability sample of 315 asymptomatic women, age 50 years or older, with no previous history of breast malignancy. METHODS: Data were collected from the entire sample of 315 women immediately postscreening using a self-report questionnaire and from a subgroup of 256 women by telephone interview at three weeks post-screening. MAIN RESEARCH VARIABLES: Satisfaction with and intentions and anxiety regarding breast cancer screening. FINDINGS: Overall, women reported a high level of satisfaction with their screening experience, including respect for privacy, encouragement to ask questions, and provision of information. Two areas of concern that participants identified were mammogram discomfort and fear about radiation risks. At the postscreening interview, women reported that breast screening had relatively little impact on social or physical aspects of their lives, but it did have a positive effect on certain emotional issues, such as their feelings of reassurance, well-being, and relaxation. CONCLUSION: Since the degree of satisfaction that participants in health services report has been shown to influence attendance patterns, assessing breast screening programs from the perspective of attendees is necessary. Such assessment can identify areas of satisfaction and concern and, thus, provide information for developing interventions aimed at promoting recruitment and retention. IMPLICATIONS FOR NURSING PRACTICE: As health educators, nurses play an important role in providing breast cancer screening information to women. As well as being knowledgeable about screening guidelines and the benefits of screening, nurses also must recognize women's concerns about radiation risks and pain or discomfort with the procedure and be prepared to provide teaching and support for these women.
