Question: The long noncoding RNA HOTAIR has been reported to be a good biomarker for poor prognosis in a variety of human cancers. However, whether HOTAIR could serve as novel biomarker to predict prognosis in cervical cancer or not is unknown. The aim of the present study was to examine the expression of HOTAIR in cervical cancers and to investigate the relationship between this lncRNA expression levels and existing clinicopathological factors and patient survival.', 'We examined the expression of HOTAIR in 218 cervical cancer tissues and matched 218 adjacent normal tissues using quantitative real-time RT-PCR and analyzed its correlation with the clinical parameters.', 'The results showed that HOTAIR expression in cervical cancer tissues was significantly upregulated compared with the matched nontumorous tissues (P < 0.0001). Increased HOTAIR expression was significantly correlated with FIGO stage (P < 0.0001), lymph node metastasis (P < 0.0001), depth of cervical invasion (P < 0.0001), tumor size (P = 0.006) and age (P = 0.020), but not other clinical characteristics. Moreover, cervical cancer patients with HOTAIR higher expression have shown significantly poorer overall survival (P < 0.0001) and disease-free survival (P < 0.0001) than those with lower HOTAIR expression. Univariate (P < 0.0001, HR = 4.566, 95 % CI 2.122-9.825) and multivariate (P = 0.012, HR = 2.863, 95 % CI 1.263-76.490). Cox regression analyses showed that HOTAIR expression served as an independent predictor for overall survival.

Question: Interfacility ground critical care transport (CCT) of patients by ambulance may be stressful. This study evaluated whether playing music during CCT reduces patient anxiety and whether objective evidence is manifested by a change in vital signs.', 'Urban teaching hospital.', 'In this prospective cohort study, music was played for eligible adult patients during CCT while recording vital signs. A questionnaire was subsequently mailed to patients to rate whether the ambulance transport was stressful, the impact music had on transport, whether music changed their anxiety, whether music made them comfortable and relaxed, and whether they would prefer music to be played on future transports. Vital signs were compared between respondents who perceived transport as stressful and those who did not.', 'One hundred two patients were enrolled; 23 respondents (22.5%) constituted the study group. Four patients (17.4%) reported CCT as stressful (average response, 4.75). Nineteen (82.6%) rated CCT as not stressful (average response, 1.63). Subjectively, patients reported a positive impact of music on transport, with improved comfort and relaxation but only a minimal decrease in anxiety. No statistically significant change in vital signs was observed between cohorts; too few patients were enrolled to generate power to detect any difference.

Question: The generation of inflammatory mediators from monocytes activated by HLA Class II antibodies is thought to play important roles in the etiology of nonhemolytic transfusion reactions. Increased permeability of endothelial cells contributes to the pathogenesis of rash, urticaria, angioedema, and pulmonary edema, which are symptoms of transfusion reactions.', 'We investigated whether inflammatory mediators released from monocytes upon stimulation by HLA Class II antibodies could increase endothelial permeability. Human endothelial cell monolayers were incubated with cell-free supernatants of peripheral blood mononuclear cells (PBMNCs) stimulated with HLA Class II antibody-containing plasma (anti-HLA-DR plasma), which has been implicated in severe nonhemolytic transfusion reactions. The permeability of endothelial cells to dextran was measured.', 'The supernatants of PBMNCs stimulated with the anti-HLA-DR plasma in corresponding antigen-antibody combinations were able to increase endothelial permeability. At least 3 hours of exposure of PBMNCs to anti-HLA-DR plasma was required to produce a supernatant that could induce a significant increase in permeability. Simultaneous addition of tumor necrosis factor alpha (TNF-alpha) and interleukin 1 beta (IL-1 beta) neutralizing antibodies to the activated PBMNC supernatant significantly reduced the increase in permeability. Treatment of the endothelial cells with an inhibitor of nuclear factor kappaB (NF-kappaB), but not inhibitors of apoptosis, significantly prevented the increase in permeability.
