This retrospective study demonstrates the clinical outcomes of patients with nonmosaic Klinefelter's syndrome (KS) who underwent preimplantation genetic testing (PGT) with frozen-thawed testicular spermatozoa. Microdissection testicular sperm extraction (micro-TESE) was performed for sperm retrieval. Next-generation sequencing (NGS) was conducted for embryo analysis. A total of 18 couples aged ≤35 years were included, and 22 oocyte retrieval cycles were completed. Euploidy was detected in 29 of 45 (64.4%) embryos. Additionally, the numbers of aneuploid and mosaic embryos detected were 8 (17.8%) and 8 (17.8%), respectively, regardless of a lack of sex chromosome abnormalities. Finally, 13 couples with euploid embryos completed 14 frozen embryo transfer (FET) cycles. Ten couples had clinical pregnancies, and 6 of them had already delivered 5 healthy babies and 1 monozygotic twin. There were also 4 ongoing pregnancies and 2 biochemical pregnancies, but no early pregnancy loss was reported. Based on our results, we speculate that for KS patients, when sperm can be obtained by micro-TESE, the cryopreservation strategy makes the ovarian stimulation procedure more favorable for female partners. The paternal genetic risk of sex chromosome abnormalities in their offspring is extremely low in men with KS. In addition to PGT, the intracytoplasmic sperm injection (ICSI) procedure is comparably effective but more economical for young nonmosaic KS couples. ICSI should be offered as an option for such couples, but monitoring by prenatal genetic diagnosis is recommended.

To evaluate outcomes between extraperitoneal robotic single-port radical prostatectomy (epR-spRP) and extraperitoneal robotic multiport radical prostatectomy (epR-mpRP) performed with the da Vinci Si Surgical System, comparison was performed between 30 single-port (SP group) and 26 multiport (MP group) cases. Comparisons included operative time, estimated blood loss (EBL), hospital stay, peritoneal violation, pain scores, scar satisfaction, continence, and erectile function. The median operation time and EBL were not different between the two groups. In the SP group, the median operation time of the first 10 patients was obviously longer than that of the latter 20 patients (P < 0.001). The median postoperative hospital stay in the SP group was shorter than that in the MP group (P < 0.001). The rate of peritoneal damage in the SP group was less than that in the MP group (P = 0.017). The pain score and overall need for pain medications in the SP group were lower than those in the MP group (P < 0.001 and P = 0.015, respectively). Patients in the SP group were more satisfied with their scars than those in the MP group 3 months postoperatively (P = 0.007). At 3 months, the cancer control, recovery of erectile function, and urinary continence rates were similar between the two groups. It is safe and feasible to perform epR-spRP using the da Vinci Si surgical system. Therefore, epR-spRP can be a treatment option for localized prostate cancer. Although epR-spRP still has a learning curve, it has advantages for postoperative pain and self-assessed cosmesis. In the absence of the single-port robotic surgery platform, we can still provide minimally invasive surgery for patients.

INTRODUCTION:
Respiratory virus (RV) infections have been implicated in acute exacerbation cardiopulmunary conditions. This study aimed to determine the prevalence of RV infections in patients admitted to the cardiology unit with acute decompensated heart failure (ADHF) in a tertiary hospitals in Singapore.
MATERIALS AND METHODS:
This was a single-centre, prospective observational study. A total of 194 adults (aged >21) admitted to the Singapore General Hospital with ADHF were recruited. A nasopharyngeal swab was taken for multiplex polymerase chain reaction (PCR) detection of influenza virus, rhinovirus, parainfluenza virus (HPIV), human coronavirus (HcoV), adenoviurs, human bocavirus (HboV), human metapneumovirus (hMPV), and respiratory syncytial virus (RSV).
RESULTS:
Twenty-five (13%) had RVs detected by RV multiplex PCR. There comprised 9 rhinoviruses (36%), 4 influenza A viruses (16%), 3 HPIV (12%), 3 HCoV (12%), 2 adenoviruses (8%), 1 human HBoV (4%), 1 hMPV (4%), and 1 RSV (4%). Symptoms-wise, cough was significantly more common in the PCR-positive group (48% vs 24%, = 0.02). There were no statistically significant differences in laboratory investigations (haemoglobin, leukocytes, platelets, creatine kinase, creatine kinase-muscle/brain, troponin T), and radiology findings between RV PCR-positive and -negative groups. The PCR-positive group did not have increased mortality or length of hospital stay.
CONCLUSION
This study identified a considerable burden of RVs in our ADHF cohort, and highlights the need for prevention of RVs in this group of patients. We also recognised the difficulty with clinical diagnosis of RVs in ADHF patients.

INTRODUCTION:
Atrial fibrillation (AF) with rapid ventricular rate (RVR) is a common diagnosis in the Emergency Department (ED) requiring evaluation and treatment. We present the characteristics and outcomes of patients presenting with primary or secondary AF in a tertiary hospital ED.
MATERIALS AND METHODS:
This retrospective cohort study included consecutive patients ≥21 years old, with a primary or secondary diagnosis of AF with RVR in the ED over a 1-year period from 1 January 2016 to 31 December 2016. Primary AF is defined as AF with no precipitating cause and secondary AF as AF secondary to a precipitating cause.
RESULTS:
A total of 464 patients presented to the ED from 1 January to 31 December 2016 with primary and secondary diagnosis of AF with RVR; 44.8% had primary diagnosis of AF whereas 55.2% had secondary AF. Overall admission rate from ED was high at 91.8% (primary 84.6% vs secondary 97.7%). Patients with primary AF were younger (68 vs 74 years, <0.001), had lower rates of cardiovascular risk factors, and shorter length of stay (median 4 vs 5 days). Within 30 days of discharge, they had lower ED reattendance (16.3% vs 25.8%, <0.001) and lower readmission (16.3% vs 25.8%, <0.001). There was no mortality in the primary AF group (0% vs 9.8%, <0.001).
CONCLUSION
Currently, majority of patients with AF with RVR are admitted from the ED. Other study suggests patients with uncomplicated primary AF have lower adverse outcomes and some could potentially be treated as outpatients.

Objective: To evaluate the randomness and representativeness of respondent- driven sampling (RDS) tool in conducting the investigation in MSM population, in Beijing, 2017. Methods: RDS tool was used to recruit MSM population for a face-to-face interview with structured questionnaire and serological tests. Results: A total of 600 MSM people were sampled and interviewed. The median number of personal network of seeds was 10, which was higher than other MSM people recruited. The numbers of recruitments by wave presented a skewed positive distribution and the highest number was in the fourth wave. It was also dramatically varied from different seeds. Three seeds had the longest chains and had recruited 184, 113 and 92 MSM people, respectively. In contrast, five seeds recruited less than 10 MSM people. Two college students were the most non-generative seeds and each recruited only 1 MSM person. After five to nine waves of sampling, the major demographic characteristics reached equilibrium. Both convergence and bottleneck plots of major demographic characteristics reached convergence, although the plots on marriage and education did not. The homophiles of characteristics were all closed to 1, except for education. The HIV positive rate appeared as 7.9% (95%CI: 4.4%-11.4%) . Conclusions: Results from this study showed that RDS could be used as a feasible sampling method for the study on MSM population with major demographic characteristics reached equilibrium. The process of recruitment appeared controllable and reasonable, showing that this could represent the MSM population in Beijing, in some degree.

7.Experience and present situation of Western China Gastric Cancer Collaboration.
Chinese Journal of Gastrointestinal Surgery 2017;20(3):247-250
The Western China Gastric Cancer Collaboration (WCGCC) was founded in Chongqing, China in 2011. At the early stage of the collaboration, there were only about 20 centers. While now, there are 36 centers from western area of China, including Sichuan, Chongqing, Yunnan, Shanxi, Guizhou, Gansu, Qinghai, Xinjiang, Ningxia and Tibet. During the past few years, the WCGCC organized routinely gastric cancer standardized treatment tours, training courses of mini-invasive surgical treatment of gastric cancer and the clinical research methodology for members of the collaboration. Meanwhile, the WCGCC built a multicenter database of gastric cancer since 2011 and the entering and management refer to national gastric cancer registration entering system of Japan Gastric Cancer Association. During the entering and collection of data, 190 items of data have unified definition and entering standard from Japan Gastric Cancer Guidelines. Nowadays, this database included about 11 872 gastric cancer cases, and in this paper we will introduce the initial results of these cases. Next, the collaboration will conduct some retrospective studies based on this database to analyze the clinicopathological characteristics of patients in the western area of China. Besides, the WCGCC performed a prospective study, also. The first randomized clinical trial of the collaboration aims to compare the postoperative quality of life between different reconstruction methods for total gastrectomy(WCGCC-1202, ClinicalTrials.gov Identifier: NCT02110628), which began in 2015, and now this study is in the recruitment period. In the next steps, we will improve the quality of the database, optimize the management processes. Meanwhile, we will engage in more exchanges and cooperation with the Chinese Cochrane Center, reinforce the foundation of the clinical trials research methodology. In aspect of standardized surgical treatment of gastric cancer, we will further strengthen communication with other international centers in order to improve both the treatment and research levels of gastric cancer in Western China.

Clinical and Experimental Emergency Medicine 2017;4(3):138-145
OBJECTIVE: Migraine headache is a chronic and disabling condition in adults. Some studies have investigated the efficacy of sodium valproate in the treatment of acute migraine, but the effectiveness and tolerability of intravenous valproate as abortive therapy remains unclear. This study aimed to evaluate the effects of sodium valproate and dexamethasone in the treatment of acute migraine. METHODS: We conducted a double-blind randomized clinical trial including 90 patients aged 18 to 65 years with acute migraine headache but no aura. Patients were randomized to receive intravenous dexamethasone (8 mg) or sodium valproate (400 mg) diluted into 4 mL of normal saline. The primary outcome measure was pain relief after 0.5, 1, 3, or 6 hours after administration. The secondary outcome criteria were the associated symptom recovery, rate of headache recurrence after 24 hours, and medication side effects. Pearson’s chi square and the t-test were employed in the data analysis. RESULTS: Of the 90 patients, 80 were investigated. The percentage of headache improvement at 0.5 hours after treatment was 55% and 67.5% in the sodium valproate and dexamethasone groups, respectively. Before-treatment and 0.5 hour after treatment pain severity visual analog scale scores were 9.05±0.90 and 3.8±3.09 in the sodium valproate group and 8.92±0.79 and 3.10±2.73 in the dexamethasone group, respectively. There were no significant intergroup differences. CONCLUSION: This randomized clinical trial showed that the intravenous injection of sodium valproate 400 mg has similar effects to those of dexamethasone for improving acute migraine headache.

BACKGROUND: The goal of this study was to evaluate whether a modified fluoroscopic technique for positioning a hook plate affected the clinical results of treating Neer type II distal clavicle fractures and Rockwood type V acromioclavicular (AC) joint separations with this device. METHODS: The study was a retrospective consecutive case series with data analysis. Sixty-four patients with a Neer type II distal clavicle fracture or a Rockwood type V AC joint injury treated between March 2009 and June 2013 were divided into 2 groups: traditional fluoroscopic technique (traditional view, 31 patients) or modified fluoroscopic technique ('hook' view, 33 patients). A visual analogue scale (VAS) score, the modified University of California-Los Angeles (UCLA) shoulder scale score, and radiographic osteolysis were the main outcome measures. RESULTS: The traditional group included a significantly larger number of patients with acromial osteolysis than the hook view group: 23 patients (74.2%) vs. 11 patients (33.3%), respectively (p=0.01). Before plate removal, the hook group reported less pain and higher UCLA shoulder scale scores than the traditional group: average VAS score, 1.55 vs. 2.26, respectively; average UCLA score, 30.88 vs. 27.06, respectively. However, there was no significant difference after plate removal. CONCLUSIONS: The hook view allows more accurate bending of the hook plate around the contour of the acromion, resulting in decreased osteolysis, decreased pain, and better function with the plate in situ.

Safety and Health at Work 2016;7(2):124-129
BACKGROUND: Work-related fatigue has a strong impact on performance and safety but so far, no agreed upon method exists to detect and quantify it. It has been suggested that work-related fatigue cannot be quantified with just one test alone, possibly because fatigue is not a uniform construct. The purpose of this study is therefore to measure work-related fatigue with multiple tests and then to determine the underlying factorial structure. METHODS: Twenty-eight employees (mean: 36.11; standard deviation 13.17) participated in five common fatigue tests, namely, posturography, heart rate variability, distributed attention, simple reaction time, and subjective fatigue before and after work. To evaluate changes from morning to afternoon, t tests were conducted. For further data analysis, the differences between afternoon and morning scores for each outcome measure and participant (Δ scores) were submitted to factor analysis with varimax rotation and each factor with the highest-loading outcome measure was selected. The Δ scores from tests with single and multiple outcome measures were submitted for a further factor analysis with varimax rotation. RESULTS: The statistical analysis of the multiple tests determine a factorial structure with three factors: The first factor is best represented by center of pressure (COP) path length, COP confidence area, and simple reaction time. The second factor is associated with root mean square of successive difference and useful field of view (UFOV). The third factor is represented by the single Δ score of subjective fatigue. CONCLUSION: Work-related fatigue is a multidimensional phenomenon that should be assessed by multiple tests. Based on data structure and practicability, we recommend carrying out further studies to assess work-related fatigue with manual reaction time and UFOV Subtest 2.
