    Comparing Rawlsian Justice and the Capabilities Approach to Justice from a Spiritually Sensitive Social Work Perspective

    鈥楾his is an electronic version of an article published in the March, 2012 special issue of the Journal of Religion and Spirituality and Social Work entitled Spirituality and Social Justice volume 31, (1-2), pp. 9-31. It is available online at http://dx.doi.org/10.1080/15426432.2012.647874This article examines two social justice theories, Rawlsian Justice and the Capabilities Approach of Sen and Nussbaum, in relation to congruence with four principles of spiritually sensitive social work. We find that although Rawlsian justice has valuable insights, it has some gaps for promoting spiritually sensitive practice. In contrast, the Capabilities Approach bears more promise for promoting spiritually sensitive social work as it meets all these ethical principles. Scholars could build on its insights to articulate a vision for spiritually sensitive social justice that can guide our profession鈥檚 approaches to macro practice and social polic

    Molecular identification of main cellular lineages as a tool for the classification of gastric cancer

    Gastric carcinomas (GC) are heterogeneous tumors comprising variable amounts of cells of different lineage phenotype, including gastric mucous cells (surface-SMC or gland-GMC) and intestinal cells (IC). The evaluation of tumor behavior has classically depended on strictly morphological classifications of tumors. Microsatellite instability (MSI) is frequently detected in GC, but whether MSI affects all gastric cellular lineages or exclusively occurs in unique cellular lineages in GC is not known. The aims of this study were to test a combination of anti-mucin antibodies to classify gastric cancer into predominant cell lineage phenotype and to determine whether MSI in GC is associated with particular cellular tumor phenotypes. Fifty-five GC were immunophenotyped with antibodies specific for SMC, GMC, or IC. DNA was extracted from tumor and non-neoplastic gastric tissues and amplified with 5 microsatellite markers. A mixed cellular pattern was the most frequent phenotype of GC (61%) and was seen in both glandular (63%) and diffuse (58%)-type tumors. No significant difference in the rate of MSI was found in tumors with predominant gastric, intestinal or mixed phenotype. However, tumors with null or low-level expression of cellular lineage differentiation markers displayed MSI more frequently than tumors with high- level expression (40% v 20%). In conclusion, different gastric carcinoma cell lineage patterns can be easily identified with the 3 immunohistochemical markers used in this study. The 3 main cellular lineage components of gastric cancer can be similarly affected by microsatellite instability, consistent with the notion that MSI is an early event in gastric carcinogenesis.

    Dolichoectasia鈥攁n evolving arterial disease

    No full text
    Dolichoectasia is an arterial disease that causes dilatation and/or tortuosity of the affected vessel. The prevalence of dolichoectasia increases with age, and this disease is also associated with other traditional cardiovascular risk factors. Multiple pathophysiological processes might lead to the development of dolichoectatic vessels, and activation of metalloproteinases and irregular turbulent blood flow seem to cause irreversible disruption of the internal elastic lamina. Intracranial dolichoectasia commonly presents with ischemic or hemorrhagic stroke, and/or cranial neuropathies. The posterior circulation is more frequently affected by the dolichoectatic process than the anterior circulation. A positive diagnosis of dolichoectasia requires visual assessment of vessel shape and, if the posterior circulation is affected, application of Smoker's criteria. Reproducible criteria that aid diagnosis of dolichoectasia in the anterior circulation are lacking. No specific treatment for dolichoectasia exists, and the surgical and medical therapies that have been used to treat this condition have not been systematically evaluated. More evidence is needed to better understand the underlying dilatatory artheriopathy that causes this disease, and to determine whether patients with dolichoectasia might benefit from early diagnosis. In this article, we provide a comprehensive review of current knowledge regarding dolichoectasia, and highlight gaps in our knowledge to aid future research
