[Q]: Thromboembolic events represent a clinically significant cause of neurological morbidity during the endovascular management of cerebral aneurysms. We have implemented an anti-thromboembolic regimen consisting of pre- and postoperative dual antiplatelet therapy, as well as postoperative anticoagulation using heparin and dextran. The aims of our study were to examine the effect of this regimen on thromboembolic rates during elective aneurysm coiling, and to elucidate risk factors associated with the development of thromboembolic events in this setting.', 'We conducted a retrospective review of patients who underwent elective intracranial aneurysm coiling between January 2005 and February 2012. The primary outcome of interest was the occurrence of a clinically significant peri-procedural thromboembolic event. Secondary outcomes included the occurrence of a central nervous system (CNS) or systemic hemorrhage.', 'During the study period, 312 patients underwent elective aneurysm coiling and six (2%) thromboembolic events occurred; three (1%) occurred in the group that received the anti-thromboembolic regimen (261 patients) and three (6%) occurred in the group that did not receive the regimen (51 patients), resulting in a statistically significant difference (P=0.024). Both the presence of a hypercoagulable state (P=0.014) and the lack of the anti-thromboembolic regimen (P=0.043) were significantly associated with the occurrence of a thromboembolic event.

[Q]: It is often suggested that immigrants with long-term pain do not benefit from rehabilitation to the same extent as native Swedish patients. In this study, an 8-week rehabilitation programme was evaluated according to its adaptation for immigrants.', "To establish whether there is a difference between immigrants and native Swedes concerning: (i) return-to-work, the patients' own estimation and their actual ability; (ii) higher level of activity; (iii) reduction in pain and analgesic use.", 'A total of 67 patients with persistent non-malignant pain completed the rehabilitation programme. Thirty (45%) of the patients were immigrants.', 'A 1- and a 3-year follow-up were made to compare the outcome between the 2 groups.', "There was no significant difference in the return-to-work rate between immigrants and native Swedes. However, the patients' prediction of their ability to return to work was higher among the non-immigrants. The level of activity was lower and pain intensity and use of analgesics were higher among the immigrants than the non-immigrants.

[Q]: Prostate cancer is a common malignancy in men, and inevitably some patients experience biochemical recurrence after radical prostatectomy. To date, there are no reliable predictors for prostate cancer recurrence, and novel predictors are urgently needed. PCDH10 (protocadherin-10) is a novel tumor suppressor gene, which is down-regulated by promoter methylation in prostate cancer. The aim of this study was to evaluate the feasibility of using PCDH10 methylation to predict the biochemical recurrence (BCR) of prostate cancer after radical prostatectomy.', 'Fresh tissue samples were obtained from 151 patients with primary prostate cancer, and from 34 patients with benign prostatic hyperplasia (BPH) as control. The methylation status of PCDH10 in prostate cancer tissues and controls were examined using methylation-specific PCR (MSP), and then associated with clinicopathological features and BCR-free survival of patients with prostate cancer.', 'We found that PCDH10 methylation was detected in 79 (52.3%) patients with prostate cancer, but no methylation was found in controls (P<0.0001). Moreover, PCDH10 methylation was significantly associated with higher preoperative prostate-specific antigen (PSA) level (P <0.0001), higher Gleason Score (P<0.0001), advanced clinical stage (P=0.0002), lymph node metastasis (P=0.0389), angiolymphatic invasion (P=0.0303), and biochemical recurrence (P=0.0068). Moreover, PCDH10 methylation was associated with poor BCR-free survival (P<0.0001), and may be used as an independent predictor of BCR-free survival (P=0.0046).
