A Q-methodology study of patients' subjective experiences of TIA

Background. An expanding body of research has focused on a range of consequences of TIA. However, no work has been conducted on the patient’s subjective experience of TIA. Aim. To capture patients’ first-hand experiences of TIA. Method. Using Q-methodology which employs both qualitative and quantitative approaches, 39 statements relating to the clinical, physical, affective, and psychological impact of TIA were distilled from the literature and from patient narratives. Consistent with conventional Q-methodology, a purposive sample of twentythree post-TIA patients sorted these statements into a normally-distributed 39-cell grid, according to the extent to which each represented their experience of TIA. Results. Casewise factoranalysis was conducted on the sorted statements. Eight factors emerged which were labelled: lack of knowledge/awareness of TIA; life impact; anxiety; interpersonal impact; depression; physical consequences; cognitive avoidance/denial; constructive optimism. Conclusions. Five of the eight factors confirmed existing research on the impact of TIA, but three new issues emerged: deep-seated anxiety, denial and constructive optimism. The emerging perspectives highlight areas to target in the management of TIA and could inform health education messages, patient information, individualised caremanagement, and enhancement of coping strategies. With development, the findings could be used as a basis for psychometric risk assessment of TIA patients

Bad Catholics: anti-Popery in This is a Short Relation (Katherine Evans and Sarah Cheevers, 1662)

This article explores how two Quaker women who were imprisoned by the Italian Inquisition encoded their critique of Roman Catholicism into their prison narrative. Quaker writing is typically antinomian and antiauthoritarian when discussing the imprisonment of Friends for religious crimes, and these two women follow this bold approach. Katherine Evans and Sarah Cheevers employ words and signs to indicate the extent of their resistance to their warders’ desires to convert them to Catholicism. Yet their text, This is a Short Relation, is also unusual in its obliqueness. In this article, I argue that there is a complex relation between speech and act, between censorship and the Quaker women’s desire to critique the prison system, its interrogators, and the Catholic faith. The result is a text that shows the Quaker message is conveyed as much through non-verbal signification on the one hand, and highly encrypted language on the other, as it is through the self-evidently critical accounts of the Roman faith which are a part of the literal meaning of the text. The women reveal, as a result, how internalised is the understanding of sacrifice and, moreover, the degree to which censorship, isolation, and fear of repercussion, has affected them

Statin prophylaxis and inflammatory mediators following cardiopulmonary bypass: a systematic review

INTRODUCTION: Induction of an inflammatory response is thought to have a significant role in the complications that follow cardiopulmonary bypass (CPB). The statin drugs are increasingly being recognized as having potent anti-inflammatory effects and hence have potential to influence an important mechanism of injury in CPB, although there is no current confirmation that this is indeed the case. Our objective was to systematically review if pre-operative prophylactic statin therapy, compared with placebo or standard of care, can decrease the inflammatory response in people undergoing heart surgery with CPB. METHODS: We performed a systematic and comprehensive literature search for all randomized controlled trials (RCTs) of open heart surgery with CPB in adults or children who received prophylactic statin treatment prior to CPB, with reported outcomes which included markers of inflammation. Two authors independently identified eligible studies, extracted data, and assessed study quality using standardized instruments. Weighted mean difference (WMD) was the primary summary statistic with data pooled using a random effects model. Descriptive analysis was used when data could not be pooled. RESULTS: Eight RCTs were included in the review, with the number of trials for each inflammatory outcome being even more limited. Pooled data demonstrated benefit with the use of statin to attenuate the post-CPB increase in interleukins 6 and 8 (IL-6, IL-8), peak high sensitivity C-reactive protein (hsCRP), and tumor necrosis factor-alpha (TNF-alpha) post-CPB (WMD [95% confidence interval (CI)] -23.5 pg/ml [-36.6 to -10.5]; -23.4 pg/ml [-35.8 to -11.0]; -15.3 mg/L [CI -26.9 to -3.7]; -2.10 pg/ml [-3.83 to -0.37] respectively). Very limited RCT evidence suggests that prophylactic statin therapy may also decrease adhesion molecules following CPB including neutrophil CD11b and soluble P (sP)-selectin. CONCLUSIONS: Although the RCT evidence may suggest a reduction in post-CPB inflammation by statin therapy, the evidence is not definitive due to significant limitations. Several of the trials were not methodologically rigorous and statin intervention was highly variable in this small number of studies. This systematic review demonstrates that there is a significant gap that exists in the current literature in regards to the potential anti-inflammatory effect of statin therapy prior to CPB

Effects of cIAP-1, cIAP-2 and XIAP triple knockdown on prostate cancer cell susceptibility to apoptosis, cell survival and proliferation

<p>Abstract</p> <p>Background</p> <p>Manipulating apoptotic resistance represents an important strategy for the treatment of hormone refractory prostate cancer. We hypothesised that the Inhibitor of Apoptosis (IAP) Proteins may be mediating this resistance and knockdown of cIAP-1, cIAP-2 and XIAP would increase sensitivity to apoptosis.</p> <p>Methods</p> <p>cIAP-1, cIAP-2 and XIAP where knocked down either individually or in combination using siRNA in androgen independent prostate cancer PC-3 cells as confirmed by real-time PCR and western blotting. Cells were then treated with TRAIL, Etoposide, or Tunicamycin, and apoptosis assessed by PI DNA staining. Apoptosis was confirmed with Annexin V labelling and measurement of PARP cleavage, and was inhibited using the pan-caspase inhibitor, zVAD.fmk. Clonogenic assays and assessment of ID-1 expression by western blotting were used to measure recovery and proliferation.</p> <p>Results</p> <p>PC-3 are resistant to TRAIL induced apoptosis and have elevated expression of cIAP-1, cIAP-2 and XIAP. Combined knockdown sensitised PC-3 to TRAIL induced apoptosis, but not to Etoposide or Tunicmycin, with corresponding increases in caspase activity and PARP cleavage which was inhibited by ZVAD.fmk. Triple knock down decreased proliferation which was confirmed by decreased ID-1 expression.</p> <p>Conclusion</p> <p>Simultaneous knock down of the IAPs not only sensitised the PC-3 to TRAIL but also inhibited their proliferation rates and clonogenic survival. The inability to alter sensitivity to other triggers of apoptosis suggests that this effect is specific for death receptor pathways and knock down might facilitate immune-surveillance mechanisms to counter cancer progression and, in combination with therapeutic approaches using TRAIL, could represent an important treatment strategy.</p
