The experience of nutritional care according to patients with head and neck cancer involved with a combined dietitian, specialist nurse and speech pathologist clinic in a regional Australia: a qualitative longitudinal study.

PURPOSE: Malnutrition is a co-morbidity of head and neck cancer (HNC) that has negative consequences for patients. Evidence-based guidelines (EBGs) provide recommendations to prevent and manage malnutrition. A clinic that combines the services of a dietitian, specialist oncology nurse and speech pathologist may promote the implementation of nutritional EBGs in regional Australia. This study aimed to explore the nutritional care experience that patients with HNC had in this setting. METHODS: A qualitative longitudinal study collected data via semi-structured interviews with HNC patients who were treated in one regional cancer care network in Australia. Interviews were conducted at key points in their HNC journey from diagnosis to 4 months post-radiotherapy. Data was analysed using a grounded theory approach. RESULTS: Ten participants completed a total of thirty-six interviews. The findings were grouped into four categories: "preparing for nutritional challenges", "multidisciplinary care directed by patient needs", "the battle to eat", and "incongruence between patient values and nutritional priorities". CONCLUSION: These findings highlight the nutritional burden associated with HNC and barriers to patients accepting nutritional support from healthcare professionals. Information provided by doctors and nurses prior to treatment may help patients prepare for the nutritional challenges ahead and accept support from dietitians. Furthermore, clinics that promote continuity through treatment and allow dietitians to lead aspects of nutritional care, in collaboration with nurses, speech pathologists and doctors, may also enhance the nutritional care experience. More qualitative research within HNC teams would provide further insight on enhancing the implementation of nutritional EBGs to improve outcomes for these patients.

Effects of 90Sr on Tree Swallow Nestlings Near Groundwater Contaminant Plumes.

Discharge of groundwater contaminant plumes has created elevated concentrations of Sr in some aquatic sediments at Chalk River Laboratories. Tree swallows (Tachycenita bicolor) feed and supply their nestlings almost exclusively with airborne insects that developed as larvae in aquatic sediments. To monitor the uptake and test for potential detriment due to Sr in a terrestrial animal, we measured the gross beta concentrations in the bone of 12-d-old tree swallow nestlings in areas having sediments with elevated levels of gross beta (Sr and Y) and in several control areas where sediment gross beta was primarily due to naturally occurring K. Nesting behavior and reproductive success of the tree swallows were similar regardless of the gross beta concentrations in sediments near their nest boxes. Radiation can damage DNA and cause micronuclei to form in cells, so we examined the frequency of micronuclei in erythrocytes of nestlings. The formation of micronuclei in the erythrocytes of the nestlings was also similar wherever nestlings were analyzed. The results revealed no significant increases even near sediments with the highest gross beta levels. At Perch Lake, where Chalk River Laboratories has a large area of Sr-contaminated sediments, the bones of 12-d-old nestlings contained gross beta concentrations as high as 29 Bq g. This would produce a skeletal dose rate of 9 µGy h, which is one-fourth of the threshold dose rate of 40 µGy h, above which detriment could occur. Failing to find any indication of detriment in the field study, we irradiated wild eggs in the lab and returned them to their nest for natural incubation, hatching, and feeding by the parents. There was an increase in formation of micronuclei following a dose of 3.2 Gy, and the other results were consistent with existing literature.
