Vitamin D seems to protect against cardiovascular disease, but the reported effects of vitaminDon patient outcomes in CKD are controversial. We conducted a prospective, double blind, randomized, placebocontrolled trial to determine whether oral activated vitamin D reduces left ventricular (LV)mass in patients with stages 3-5 CKD with LV hypertrophy. Subjects with echocardiographic criteria of LV hypertrophy were randomly assigned to receive either oral paricalcitol (1 μg) one time daily (n=30) ormatching placebo (n=30) for 52 weeks. The primary end point was change in LV mass index over 52 weeks, which was measured by cardiac magnetic resonance imaging. Secondary end points included changes in LV volume, echocardiographic measures of systolic and diastolic function, biochemical parameters of mineral bone disease, and measures of renal function. Change in LV mass index did not differ significantly between groups (median [interquartile range], 22.59 [26.13 to 0.32] g/m2 with paricalcitol versus 24.85 [29.89 to 1.10] g/m2 with placebo). Changes in LV volume, ejection fraction, tissue Doppler-derived measures of early diastolic and systolicmitral annular velocities, and ratio of earlymitral inflowvelocity to early diastolic mitral annular velocity did not differ between the groups. However, paricalcitol treatment significantly reduced intact parathyroid hormone (P,0.001) and alkaline phosphatase (P=0.001) levels as well as the number of cardiovascular-related hospitalizations compared with placebo. In conclusion, 52 weeks of treatment with oral paricalcitol (1 mg one time daily) significantly improved secondary hyperparathyroidism but did not alter measures of LV structure and function in patients with severe CKD.

Activating mutations of the epidermal growth factor receptor (EGFR) gene in non-small cell lung cancer predict for a favorable clinical response to tyrosine kinase inhibitor therapy. Although Sanger sequencing is a conventional method to detect EGFR gene mutations, multiplex real-time allele-specific polymerase chain reaction (PCR) systems are increasingly used in the routine molecular diagnostic setting. We aim to evaluate 2 proprietary real-time PCR assays (cobas and therascreen) against Sanger sequencing in the detection of EGFR gene mutations. The overall concordance rate between cobas and therascreen assays with Sanger sequencing was 89% and 88%, respectively, and increased to 96% and 98%, respectively, if the mutations not covered were excluded. The cobas assay showed a superior coverage of exon 20 mutations, but L861Q was not targeted. The nature of specimen, DNA integrity, and tumor cell content are factors that affect the assay performance. DNA extracted from cell block and clot of pleural fluid gave rise to 1 invalid call and 1 false-negative result by the cobas assay and 1 missed T790M mutation and 1 false-negative result by the therascreen assay. Both assays are around 5 times more expensive compared with Sanger sequencing in terms of reagent cost. We conclude that both assays prove to be a rapid, simple, and validated method in detecting the most common and clinically significant EGFR gene mutations in non-small cell lung cancer. Although less convenient compared with real-time PCR assays, Sanger sequencing is cheaper in terms of reagent cost and allows the detection of rare or novel EGFR gene mutations.

Introduction: Screening mammogram can decrease the mortality of breast cancer. Studies show that women avoid mammogram because of fear of pain, diagnosis, and radiation. This study aimed to evaluate the effectiveness of a radiolucent pad (MammoPad; Hologic Inc, Bedford [MA], US) during screening mammogram to reduce pain in Chinese patients and the possibility of glandular dose reduction. Methods: This case series was conducted in a private hospital in Hong Kong. Between November 2011 and January 2012, a total of 100 Chinese patients were recruited to our study. Left mammogram was performed without MammoPad and served as a control. Right mammogram was performed with the radiolucent MammoPad. All patients were then requested to complete a simple questionnaire. The degree of pain and discomfort was rated on a 0-10 numeric analogue scale. Significant reduction in discomfort was defined as a decrease of 10% or more. Results: Of the 100 patients enrolled in this study, 66.3% of women reported at least a 10% reduction in the level of discomfort with the use of MammoPad. No statistical differences between age, breast size, and the level of discomfort were found. Conclusion: The use of MammoPad significantly reduced the level of discomfort experienced during mammography. Radiation dose was also reduced. © 2016, Hong Kong Academy of Medicine Press.

Nasopharyngeal carcinoma (NPC) is endemic in China and Southeast Asia where it is tightly associated with infections by Epstein-Barr virus (EBV). The role of tumor-associated viral antigens in NPC renders it an appealing candidate for cellular immunotherapy. In earlier preclinical studies, a novel adenoviral vector-based vaccine termed AdE1-LMPpoly has been generated that encodes EBV nuclear antigen-1 (EBNA1) fused to multiple CD8 + T-cell epitopes from the EBV latent membrane proteins, LMP1 and LMP2. Here, we report the findings of a formal clinical assessment of AdE1-LMPpoly as an immunotherapeutic tool for EBV-associated recurrent and metastatic NPC. From a total of 24 patients with NPC, EBV-specific T cells were successfully expanded from 16 patients with NPC (72.7%), whereas six patients with NPC (27.3%) showed minimal or no expansion of virus-specific T cells. Transient increase in the frequencies of LMP1&2- and EBNA1-specific T-cell responses was observed after adoptive transfer to be associated with grade I flu-like symptoms and malaise. The time to progression in these patients ranged from 38 to 420 days with a mean time to progression of 136 days. Compared with patients who did not receive T cells, the median overall survival increased from 220 to 523 days. Taken together, our findings show that adoptive immunotherapy with AdE1-LMPpoly vaccine is safe and well tolerated and may offer clinical benefit to patients with NPC. ©2012 AACR.

Background. The objective of this study was to examine the effects of low-dose pregabalin on the analgesic efficacy, side-effects, and recovery profile in patients undergoing laparoscopic cholecystectomy. Methods. One hundred and sixty-two patients aged 18-65 yr, of ASA physical status I-III, undergoing elective outpatient laparoscopic cholecystectomy were recruited and randomized in this prospective, placebo-controlled, double-blind study to receive one of the following study medications orally: pregabalin 50 mg, pregabalin 75 mg, or placebo, 1 h before surgery and then every 12 h after operation for a total of three doses. Postoperative numeric pain scores, analgesic consumption, recovery score (QoR-40), and side-effects (opioid-related symptom distress scale) were assessed in the early postoperative period (every 15 min during the first hour, at 90, 120 min, 6, and 12 h) and at days 1, 2, and 7. Data were analysed using an intention-to-treat method. Results. Compared with the placebo group, the pain scores were lower in the pregabalin 75 mg group in the first 90 min after surgery (P<0.05). Pregabalin 50 mg resulted in pain reduction at 30 and 45 min (P<0.05) relative to placebo. The analgesic consumption, side-effects, and recovery scores were similar among the three groups. Conclusions. Perioperative administration of pregabalin 75 mg provided limited analgesic benefit in the postoperative period. An updated meta-analysis confirms this finding (see Supplementary material). © The Author [2010]. Published by Oxford University Press on behalf of the British Journal of Anaesthesia.

The development of modern coronary stent platforms has transformed the landscape of interventional cardiology. Contemporary coronary stents are much more deliverable than older-generation stents. However, longitudinal deformation has emerged as a "new" complication in modern coronary stent platforms. Although most reported cases of longitudinal stent deformation involve mechanical or technical mishaps, it appears that it is more frequently associated with a particular stent design: the "offset peak-to-peak" stent design. This review summarizes the latest data around stent performance. Within this context, two clinical cases where longitudinal deformation was observed in the absence of any mechanical mishaps are also presented. Collectively, this evidence suggests that stent design may be a major determinant of stent performance.

ABSTRACT: A bedridden 90-year-old man with fever and elevated prostate-specific antigen (PSA) (49 ng/mL) was referred for differentiation between infection and tumor. F-FDG PET/CT was negative for infection, but Ga-PSMA PET/CT showed multiple lesions in prostate gland with infiltration to bladder wall and seminal vesicle, consistent with locally advanced prostate cancer. The lesion with the highest Ga-PSMA uptake was strongly avid for Ga-DOTATOC, suggesting neuroendocrine tumor differentiation. After hormonal therapy, PSA normalized, but chromogranin-A increased (from 251 to 398 ng/mL), inferring progression of neuroendocrine tumor differentiation. Advanced prostate cancer may require investigation for pathological neuroendocrine transformation, although PSA may suggest improvement. Copyright © 2016 Wolters Kluwer Health, Inc.

Tomotherapy delivers an intensity-modulated radiation therapy (IMRT) treatment by the synchronization of gantry rotation, multileaf collimator (MLC), and couch movement. This dynamic nature makes the quality assurance (QA) important and challenging. The purpose of this study is to develop some methodologies using an ArcCHECK for accurate QA measurements of the gantry angle and speed, MLC synchronization and leaf open time, couch translation per gantry rotation, couch speed and uniformity, and constancy of longitudinal beam profile for a Tomotherapy unit.Four test plans recommended by AAPM Task Group 148 (TG148) and the manufacturer were chosen for this study. Helical and static star shot tests are used for checking the leaves opened at the expected gantry angles. Another helical test is to verify the couch traveled the expected distance per gantry rotation. The final test is for checking the couch speed constancy with a static gantry. ArcCHECK can record the detector signal every 50 ms as a movie file, and has a virtual inclinometer for gantry angle measurement. These features made the measurement of gantry angle and speed, MLC synchronization and leaf open time, and longitudinal beam profile possible. A shaping parameter was defined for facilitating the location of the beam center during the plan delivery, which was thereafter used to calculate the couch translation per gantry rotation and couch speed. The full width at half maximum (FWHM) was calculated for each measured longitudinal beam profile and then used to evaluate the couch speed uniformity. Furthermore, a mean longitudinal profile was obtained for constancy check of field width. The machine trajectory log data were also collected for comparison. Inhouse programs were developed in MATLAB to process both the ArcCHECK and machine log data.The deviation of our measurement results from the log data for gantry angle was calculated to be less than 0.4. The percentage differences between measured and planned leaf open time were found to be within 0.5% in all the tests. Our results showed mean values of MLC synchronization of 0.982, 0.983, and 0.995 at static gantry angle 0, 45, and 135, respectively. The mean value of measured couch translation and couch speed by ArcCHECK had less than 0.1% deviation from the planned values. The variation in the value of FWHM suggested the couch speed uniformity was better than 1%. The mean of measured longitudinal profiles was suitable for constancy check of field width.Precise and efficient methods for measuring the gantry angle and speed, leaf open time, couch translation per gantry rotation, couch speed and uniformity, and constancy of longitudinal beam profile of Tomotherapy using ArcCHECK have been developed and proven to be accurate compared with machine log data. Estimation of the Tomotherapy binary MLC leaf open time is proven to be precise enough to verify the leaf open time as small as 277.8 ms. Our method also makes the observation and quantification of the synchronization of leaves possible.
