CAREGIVING FOR A FAMILY MEMBER WITH HEAD AND NECK CANCER

Objective: To know the perception of informal caregivers regarding the care for a family member with head and neck cancer. Methods: Qualitative study conducted between March and May 2014 in the radiotherapy outpatient center of the Centro de Alta Complexidade em Oncologia – CACON (Oncology High Complexity Center) of the Hospital Universitário de Brasília – HUB (University Hospital of Brasília) using semi-structured interviews with nine caregivers about the experience of caring for family members. Data underwent Content Analysis and four units of meaning were identified: “Representation of cancer in the Family���, “The care as debt, individual reward or reconstruction of family ties”, “Repercussions of cancer on the caregiver’s personal life” and “Social support and network used by caregivers”. Results: Feelings of sadness and surprise at the moment of diagnosis were attributed to cancer, as well as the idea of punishment. The care was seen as personal satisfaction, accomplishment and opportunity for family rapprochement. Work overload and change in routine were altered functions. Religiosity, exchange of experience in the waiting room and institutional support appeared as coping strategies. Conclusion: The experience of caring for family members with head and neck cancer directly interferes in the lives of caregivers. Pointing out the institutional embracement as a strategy within the social network reinforces the importance of integrating the caregivers as a significant part of the health care plan developed by the health team.

Cloning of the ω-secalin gene family in a wheat 1BL/1RS translocation line using BAC clone sequencing

Background: Wheat 1BL/1RS translocation lines are planted around the world for their disease resistance and high yield. Most of them are poor in bread making, which is partially caused by ω-secalins that are encoded by the ω-secalin gene family, which is located on the short arm of rye chromosome 1R (1RS). However, information on the structure and evolution of the ω-secalin gene family is still limited. Results: We first generated a physicalmap of the ω-secalin gene family covering 195 kb of the Sec-1 locus based on sequencing three bacterial artificial chromosome (BAC) clones of the 1BL/1RS translocation wheat cultivar Shimai 15. A BAC contig was constructed spanning 168 kb of the Sec-1 locus on 1RS. Twelve ω-secalin genes were arranged in a head-to-tail fashion, separated by 8.2–21.6 kb spacers on the contig, whereas six other ω-secalin genes were arranged head-to-tail, separated by 8.2–8.4 kb of spacers on clone BAC125. The 18 ω-secalin genes can be classified into six types among which eight ω-secalin genes were expressed during seed development. The ω-secalin genes with the 1074-bp open reading frame (ORF) represented the main population. Except for two pseudogenes, the N-terminal of the ω-secalin gene was conserved, whereas variations in the C-terminal led to a change in ORF length. The spacers can be sorted into two classes. Class-1 spacers contained conserved and non-conservative sequences. Conclusion: The ω-secalin gene family consisted of at least 18 members in the 1BL/1RS translocation line cv. Shimai 15. Eight ω-secalin genes were expressed during seed development. Eighteen members may originate from a progenitor with a 1,074-bp ORF. The spacers differed in length and sequence conservation.
