Thunderstorm asthma: a review, risks for Aotearoa New Zealand, and health emergency management considerations.

AIM: To provide an up-to-date review of thunderstorm asthma (TA), identifying causative factors, and to discuss implications for management of TA in New Zealand. METHODS: A literature search was carried out to identify articles that investigate the characteristics and causative factors of TA. Nine electronic databases were searched, yielding 372 articles, reduced to 30 articles after screening for duplication and relevance. RESULTS: TA is globally rare, with 29 reported events since 1983, but is expected to increase in frequency as Earth warms. Triggers include both pollen (particularly ryegrass pollen) and fungal spores. Individual risk factors include outdoor exposure, sensitivity to triggering allergens and history of seasonal allergic rhinitis. History of asthma is not a strong risk factor but is associated with severity of outcome. Limited data on demographic characteristics suggests that individuals aged between 20 and 60 and (in Australasia) of Asian/Indian ethnicity are at higher risk. A single TA event has been reported in New Zealand to date, but much of New Zealand may be at risk of future events given that ryegrass pastures are widely distributed, and summer thunderstorms can occur anywhere. CONCLUSIONS: We recommend developing rapidly deployable public messaging to support the health emergency management response to future TA events, together with the instigation of routine aeroallergen monitoring.

Effect of certification in oncology nursing on nursing-sensitive outcomes.

The study compared certified nurses with noncertified nurses for symptom management of nausea, vomiting, and pain; patient satisfaction; and nurse satisfaction to determine the effect of certification in oncology nursing on those nursing-sensitive outcomes. A total of 93 nurses-35 (38%) of them certified in oncology nursing-and 270 patients completed surveys. Chart audits provided additional data on symptom management. Certified nurses scored higher than noncertified nurses on the Nurses' Knowledge and Attitudes Survey Regarding Pain as well as the Nausea Management: Nurses' Knowledge and Attitudes Survey. The chart audits showed that certified nurses followed National Comprehensive Cancer Network guidelines for chemotherapy-induced nausea and vomiting (CINV) management more often than noncertified nurses. The study demonstrated that job satisfaction is fairly high for oncology nurses and patient satisfaction is high. In general, cancer pain and CINV were managed well but improvements can be made. Nurses and physicians continuously should be educated on evidence-based guidelines for symptom management of cancer pain and CINV, and a CINV knowledge and attitude assessment tool should be developed.

Dietary soy intake and breast cancer risk.

PURPOSE/OBJECTIVES: To conduct a metasynthesis of the literature on human studies of the relationship between dietary soy intake and breast cancer risk. DATA SOURCES: Publications in English reporting human studies were searched with the terms soy and breast cancer, using Ovid, PubMed, and EBSCO databases. Only human studies investigating the relationship of soy intake to breast cancer development in women published from January 1997 through June 2008 were included in the review. DATA SYNTHESIS: A total of 364 publications were located; 18 of the studies met the inclusion criteria and 18 additional studies were located through other publications identified in the search. Because four articles reported on the same two studies, a total of 34 studies were included in the review. CONCLUSIONS: The naturally occurring dietary intake of soy food or its components appears safe for women without breast cancer; however, the safety of high supplements of soy or its components is less certain. IMPLICATIONS FOR NURSING: Nurses should become more knowledgeable about soy foods and supplements and include soy intake in dietary assessments. Nurses caring for women at high risk for or with a history of breast cancer should confer with dietitians on current practice recommendations. Women with health issues should avoid initiating high intake of soy dietary supplements until the possible effects are better understood.

The study compared certified nurses with noncertified nurses for symptom management of nausea, vomiting, and pain; patient satisfaction; and nurse satisfaction to determine the effect of certification in oncology nursing on those nursing-sensitive outcomes.

Certified nurses scored higher than noncertified nurses on the Nurses' Knowledge and Attitudes Survey Regarding Pain as well as the Nausea Management: Nurses' Knowledge and Attitudes Survey.
