Q: 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.

Q: Evidence regarding the mortality rate after administration of the pandemic influenza A (H1N1) 2009 vaccine on patients with underlying diseases is currently scarce. We conducted a case-control study in Japan to compare the mortality rates of patients with idiopathic interstitial pneumonia after the vaccines were administered and were not administered.', 'Between October 2009 and March 2010, we collected clinical records in Japan and conducted a 1:1 matched case-control study. Patients with idiopathic interstitial pneumonia who died during this period were considered case patients, and those who survived were considered control patients. We determined and compared the proportion of each group that received the pandemic influenza A (H1N1) 2009 vaccine and estimated the odds ratio. Finally, we conducted simulations that compensated for the shortcomings of the study associated with adjusted severity of idiopathic interstitial pneumonia.', 'The case and control groups each comprised of 75 patients with idiopathic interstitial pneumonia. The proportion of patients who received the pandemic influenza A (H1N1) 2009 vaccine was 30.7% and 38.7% for the case and control groups, respectively. During that winter, the crude conditional odds ratio of mortality was 0.63 (95% confidence interval, 0.25-1.47) and the adjusted conditional odds ratio was 1.18 (95% confidence interval, 0.33-4.49); neither was significant. The simulation study showed more accurate conditional odds ratios of 0.63-0.71.

Q: Sitosterolemia, a rare genetic disorder characterized by profoundly elevated plasma sitosterol concentrations, is associated with premature atherosclerosis in some individuals. This study was conducted to evaluate if the modest sitosterol elevations seen in the general population are also associated with the occurrence of coronary events.', 'A nested case-control study using stored samples from male participants in the Prospective Cardiovascular Münster (PROCAM) study was performed. Each of 159 men who suffered a myocardial infarction or sudden coronary death (major coronary event) within 10 years of follow-up in PROCAM was matched with 2 controls (N = 318) by age, smoking status, and date of investigation. Analysis was performed using conditional logistic regression. Plasma sitosterol concentrations were elevated in cases compared with controls (4.94 +/- 3.44 micromol/L versus 4.27 +/- 2.38 micromol/L; P = 0.028). The upper quartile of sitosterol (>5.25 micromol/L) was associated with a 1.8-fold increase in risk (P < 0.05) compared with the lower three quartiles. Among men with an absolute coronary risk > or = 20% in 10 years as calculated using the PROCAM algorithm, high sitosterol concentrations were associated with an additional 3-fold increase in the incidence of coronary events (P = 0.032); a similar, significant relationship was observed between a high sitosterol/cholesterol ratio and coronary risk (P = 0.030).
