Body Mass Index Is More Predictive of Progenitor Number in Bone Marrow Stromal Cell Population Than Age in Men: Expanding the Predictors of the Progenitor Compartment

Research has focused on in vitro expansion of bone marrow stromal cells with the aim of developing cell-based therapies or tissue-engineered constructs. There is debate over whether there is a reduction in stem cells/osteoprogenitors in the bone marrow compartment with increasing age. The aim of this study was to investigate patient factors that affect the progenitor pool in bone marrow samples. Six milliliters of marrow aspirate was obtained from the femoral canal of 38 primary hip replacement patients (aged 28-91). Outcome measures were total nucleated cell count, colony-forming efficiency, alkaline phosphatase expression, and expression of stem cell markers. There was a nonsignificant negative correlation between age and both colony-forming efficiency and stem cell marker expression. However, body mass index showed a positive, significant correlation with colony area and number in men-accounting for up to 75% of the variation. In conclusion, body mass index, not age, was highly predictive of the number of progenitors found in bone marrow, and this relationship was sex specific. These results may inform the clinician's treatment choice when considering bone marrow-based therapies. Further, it highlights the need to widen research into patient factors that affect the adult stem cell population beyond age and reinforces the need to consider sexes separately.

Resilience and Vulnerability in the Midst of Socio-Political Violence in Northern Ireland: One Family’s Experience of a Paramilitary Style Assault.

This article focuses on the experience of one particular family living amidst the socio-political violence in Northern Ireland to illustrate the impact of a particular traumatic event – a paramilitary assault due to mistaken identity. These attacks are often colloquially referred to as a ‘punishment shootings’ or ‘beatings’. The therapeutic process is described in narrative terms, providing a framework for; understanding the systemic effect on family relationships of the initial problematic ‘storying’ of the event, and the process of ‘re-storying’ a new more coherent narrative that integrates the trauma experience. Thus, temporary family vulnerability becomes transformed into increased family resilience. This process has general applicability in work with traumatized families.

Assessing the daily consistency of bladder filling using an ultrasonic Bladderscan device in men receiving radical conformal radiotherapy for prostate cancer

Consistency in target organ and organ at risk position from planning to treatment is an important basic principle of radiotherapy. This study evaluates the effectiveness of bladder-filling instructions in achieving a consistent and reproducible bladder volume at the time of planning CT and daily during the course of radical radiotherapy for prostate cancer. It also assessed the rate of bladder filling before and at the end of radiotherapy.

Quality of life in men receiving radiotherapy and neo-adjuvant androgen deprivation for prostate cancer:Results from a prospective longitudinal study

Aim. To report a study measuring the quality of life and side effects in men receiving radiotherapy and hormone ablation for prostate cancer up to 1year after treatment. Background. Prostate cancer incidence is increasing with the result that more men are living longer with the disease and the side effects of treatment. It is important to know the effects this has on their quality of life. Design. Survey. Method. Between September 2006-September 2007, all men who were about to undergo radical conformal radiotherapy ± neo-adjuvant androgen deprivation for localized prostate cancer were invited to participate in the study; 149 men were recruited. They completed the European Organization on Research and Treatment of Cancer quality of life questionnaire C-30 and Prostate Cancer module PR25 at four time-points. Results. At 4-6weeks after radiotherapy, participants experienced the biggest relative decline in global quality of life, social, physical, and role functioning and an increase in treatment side effects. At 6months postradiotherapy the majority of men experienced an improvement in their side effects. However, a minority of men were experiencing severe side effects of radiotherapy at 1year post-treatment. Single men and men who had a low quality of life prior to radiotherapy, reported a lower quality of life at 1year after treatment in comparison to married men. Conclusion. Men with prostate cancer suffer limitations due to the symptoms they experience and disruption to their quality of life. It is essential that nurses develop and deliver follow-up care which is flexible and appropriate to the individual needs of these men. © 2012 Blackwell Publishing Ltd.

Violence in the Lives of Children and Youth in “Post-Conflict” Northern Ireland

While Northern Ireland experiences relative peace and political stability, its violent past is normalized in murals and commemorations, the language and posturing of opposition politics, segregated communities and social life. In “post-conflict” Northern Ireland, children and youth disproportionately experience paramilitary-style attacks and routine sectarian violence. The violence of poverty and restricted opportunities within communities debilitated by three decades of conflict is masked by a discourse of social, economic and political progress. Drawing on qualitative research, this paper illustrates the continued legacy and impacts of violence on the lives of children and youth living in post-ceasefire Northern Ireland. It discusses the prominence of violence—sectarian, racist, political, “everyday,” domestic, “informal”—in young people's accounts and the impacts on their safety, sense of belonging, identity formation, use of space and emotional well-being. The paper concludes by challenging narrow and reductionist explanations of violence, arguing the need to contextualize these within local, historical, political, cultural and material contexts.
