Understanding the factors that influence stroke survivors to begin or resume exercise: a qualitative exploration.

BACKGROUND: Exercise after stroke has the potential to increase survivors' physical function and decrease disability. However, despite health professional reporting they recommend exercise to stroke survivors, the majority are physically inactive. Stroke survivors have previously expressed a lack of adequate knowledge and skills to engage in exercise. OBJECTIVES: The aim of this study was to understand why active stroke survivors chose to (re)engage in exercise and how they went about doing so. A secondary aim was to understand if health professionals had a role in facilitating exercise engagement. METHODS: Semi-structured interviews were conducted with stroke survivors who regularly engaged with exercise. Seven people aged between 60 and 71 years participated in the study. Time since stroke varied from 1 to 13 years. A reflexive thematic analysis approach was used to analyze interviews. RESULTS: Exercise was spoken about in a positive light. For some, exercise had always been important, for others it became important after their stroke. The themes of Changing Support Over Time, Old and New Identity and Proactively Impacting the Future were developed. The participants felt that health professionals often facilitated engagement in exercise, although the type of support that was most valued differed at different points in the post-stroke journey. CONCLUSIONS: Authoritative support from health professionals and family members helped participants to engage in exercise in the early stages after stroke. Collaboration and being part of a team was appreciated for ongoing exercise engagement. Exercise provided hope as participants developed their identity after stroke.

Stories of Identity from High Performance Male Boxers in Their Training and Competition Environments.

The current submission was conceived to broaden the discussion around male athletic identities by exploring the stories told by four members of the Canadian National Boxing Team. The athletes' stories were elicited through an arts-based method followed by a conversational interview. Stories were then analyzed using an interpretive thematic analysis. Three salient themes were found-fluid masculinity, ethnicity brings an edge to boxing, and expressing identity through language. These themes present accounts that highlight how socially, culturally, and historically dominant narratives can allow athletes to feel comfortable in presenting the identities they might reveal or feel constrained from doing so due to factors outside of their control. The need to develop training and competition contexts that allow for the empowerment of athletes' individually distinct identities is highlighted as a method to ensuring the positive mental health of elite level athletes.

Feasibility of in situ hybridisation with chromosome specific DNA probes on paraffin wax embedded tissue.

The feasibility was studied of in situ hybridisation using chromosome specific DNA probes on paraffin wax embedded normal and malignant tissues from different organs. Both isolated nuclei and 5 microns sections were used in in situ hybridisation experiments with biotinylated repetitive DNA probes specific for the centromeric regions of chromosomes 1 and 17. The hybridisation results were visualised with peroxidase-diaminobenzidine. The optimal pretreatments with sodium thiocyanate and pepsin were experimentally defined for the different tissues. Although interphase cytogenetics on paraffin wax embedded tissue is possible, the results indicate that it has its limitations, compared with investigations on fresh tumour tissue.

Detection of chromosome aneuploidy in interphase nuclei from human primary breast tumors using chromosome-specific repetitive DNA probes.

We have used in situ hybridization with chromosome specific repetitive DNA sequences as a probe to reveal particular chromosomes as distinct spots or clusters of signal within interphase nuclei. Using karyotypically defined cells and cell lines, we show that the number of signals obtained per nucleus correlates with the number of particular chromosomes present in that nucleus. Further, admixtures of karyotypically different cell lines could be detected. In situ hybridization of nuclei and metaphase spreads derived from the breast cancer cell line MCF-7 shows that a deviant number of spots/nucleus indicates a numerical and/or structural chromosomal aberration. In seven primary breast tumors studied, we detected numerical aberrations of the target sites of chromosomes 1 and/or 18. Although all had a single peak in DNA flow measurements, six of the cases appeared to be heterogeneous with respect to their spots/nucleus content.
