Abstract
308 Background: A multidisciplinary tumor board (MTB) provides an interdisciplinary approach for decision-making in cancer care. Efficient conduction of MTBs is importantfor optimal patient management. It is, however, often observed that prepared patient cases are not discussed during tumor boards due to limited time or incomplete information, which could cause delaytocaredecisions and/or the initiation of treatments. It remains unknown whether digital technologies canreduce the rate of failure to discuss during MTBs. Methods: A prospective cohort study was undertaken to evaluate the preparation & conduction of MTBs pre- & post-implementation of the NAVIFY Tumor Board (NTB) solution at Missouri University Health Care (MU), including the Ear, Nose & Throat (ENT) MTB. The NTB is a cloud-based workflow product, integrated with the hospital EMR, that aggregates and displays relevant clinical information. NTB was introduced to theMUENT MTB on Oct 10, 2018. Results: Pre-NTB implementation, data was collected from 42 ENT MTBs. A total of 551 patient cases were prepared for MTBs, but only 423 patient cases were discussed. This was an average “failure-to-discuss” rate of 19.4% per meeting (SD = 15.6%). After NTB implementation, data was collected from 7 MTBs where a total of 70 patient cases were prepared and discussed. There were no instances of failure to discuss, and as such, was significantlyreduced after the implementation of NTB (Mann-Whitney U test, p = 0.0004). The average number of patient cases discussed per meeting pre- and post-NTB implementation did not change (Mann-Whitney U test, p > 0.1) and meeting duration was the same. Conclusions: Introduction of the NTB did not change the weekly number of cases discussed, but did significantly reduce the failure to discuss rates for ENT MTB cases. Reducing failure to discuss rates could decrease the overall time to clinical decision and the initiation of treatment, which could potentially improve patient outcomes. Additional studies are needed to examine the impact of digital solutions on the quality of clinical care.

Abstract
Abstract
Background: The conventional way of patient treatment should be following guidelines. While in clinical practice, patients received treatments very often away from suggested guideline. In this report, we reviewed glioma patients received real world treatment at Sun Yat-sen University Cancer Center (SYSUCC) and results of this patient series.
Methods: Total of 1215 glioma patients received surgery at SYSUCC from 2000 to 2017 were enclosed for analysis. The pathologic diagnosis of patients has followed WHO classification (initially 2007 standard, than 2016 standard).
Results: A total of 1001 newly diagnosed brain glioma patients were analyzed, including 90 cases WHO grade I, 307 grade II, 239 grade III and 365 grade IV. The median age of onset was 14 (1–75), 35 (2–69), 41 (8–82) and 50 (2–86) years old, respectively, for grade I, II, III and IV glioma patients. Tumor total resection was achieved in 567 patients (57.5%). Among all patients, 331 high-grade gliomas (54.8%) and 159 low-grade glioma (40.1%) received radiotherapy, whereas 285 high-grade gliomas (47.1%) and 80 low-grade tumors (20.2%) received chemotherapy. Among high-grade gliomas, the median OS of glioblastoma, anaplastic astrocytoma and anaplastic oligodendroglial tumors were 17.7 months (15.7–19.7 months), 33.7 months (24.0–43.4 months) and 110.6 months (43.5–177.7 months), respectively, whereas the median OS of low-grade gliomas was not reach. The 5-year survival rate of grade I, II, III and IV gliomas was 94.7%, 73.7%, 45.1% and 18.6%, respectively. Multivariate analysis identified that onset age, Karnofsky performance status, tumor location, preoperative seizure, pathological subtype, resection extent and post-surgical treatment were independent predictors of OS for patients with high-grade gliomas. Patients received post-surgical radiotherapy and (or) chemotherapy had better survival than those without adjuvant treatment (grade III: 53.3 vs. 20.6 months, p =0.012; grade IV: 22.9 vs. 12.3 months, p < 0.001). For low-grade gliomas, patients’ age, Ki-67 index, tumor subtype and resection extent were associated with clinical outcomes.
Conclusions: Glioma patients received treatments do not always following guidelines in clinical practice. Although standard care for patients may beneficial for prognosis, personalized treatment may more acceptable for patients and even resulting better outcome which should keep in mind in routine clinical practice.

Abstract
Objective: To study the clinical characteristics of outpatients with hand, foot and mouth disease (HFMD) caused by different serotypes of enteroviruses. Methods: This was a prospective study. From February 2017 to March 2018, 563 outpatients with HFMD were enrolled by systematic sampling in the Department of Infectious Diseases, Henan Children's Hospital. Throat swabs were collected to determine the serotypes via PCR. Demographic, clinical, and laboratory data were collected by standard questionnaire. All cases were followed up twice at 2 and 9 weeks after the initial outpatient visit through telephone interview. A total of 563 cases were enrolled and 555 (98.6%) cases were positive for human enteroviruses, including 338 (60.9%) males. Analyses were stratified by enterovirus serotypes, Chi square test or Fisher's exact test, Rank sum test was used for comparison among different groups. Results: The age of 555 cases was 24.2 (16.4, 41.3) months. Among them 44.0% (224 cases) were identified as coxsackievirus (CV)-A6, while 189 cases, 35 cases, 14 cases and 73 cases were identified as CV-A16, enterovirus (EV)-A71, CV-A10 and other serotypes, respectively. Fever (≥37.5 ℃) was present in 51.4% (285/555) of laboratory confirmed cases. The proportions of fever in cases of CV-A6 (68.9%(168/244)) and CV-A10 (12/14) were significantly higher than those in cases of CV-A16 (31.7%(60/189),χ(2)=57.344,14.313,both P=0.000), other serotypes (43.8%(32/73),χ(2)=15.101 and 8.242, P=0.000 and 0.004) and EV-A71 (37.1%(13/35), χ(2)=13.506 and 9.441, P=0.000 and 0.002) respectively. There was no significant difference between CV-A6 and CV-A10 in presentation of fever (χ(2)=1.785, P=0.182). There were 359 cases (64.7%) with eruptions in mouth, hands, feet and buttocks. Cases infected with EV-A71 had the highest proportions (74.3%(26/35)) of rash emerging simultaneously in mouth, hands, feet, and buttocks. The proportion in cases of CV-A16, CV-A6, CVA10 and other serotype were 73.5% (139/189), 61.9% (151/244), 7/14 and 49.3% (36/73), respectively. The proportion of rash on other parts of body, such as face, limbs or torso in cases infected with CV-A6 (16.8% (41/244)) was the higherest and the proportion in cases of CV-A16, EV-A71, CV-A10 or other serotypes were 8.5% (16/189) , 5.7% (2/35) , 1/14, 6.8% (5/73) , respectively. None of these cases developed serious complications. Desquamation occurred in 45.5% (179/393) cases 7.5 (5.0, 9.0) days after disease onset and 13.5% (53/393) cases showed onychomadesis 31.0 (18.0, 33.5) days after disease onset. The proportion of desquamation and onychomadesis associated with CV-A6 (64.2% (95/148) and 31.8% (47/148)) was significantly higher than CV-A16 (31.8% (49/154) and 1.3% (2/154), χ(2)=33.601 and 52.482, both P=0.000) and other serotypes (38.0%(19/50) and 6.0%(3/50),χ(2)=10.236 and 12.988, P=0.001 and 0.000). Desquamation appeared more in cases of CV-A6 than in cases of CV-A10 (2/11,χ(2)=9.386, P=0.002), with the proportion of onychomadesis higher in CV-A6 than in EV-A71 (3.3% (1/30),χ(2)=11.088, P=0.001). Conclusion: Clinical manifestation such as fever, rash emerging parts, desquamation and onychomadesis are different among outpatient HFMD cases infected with CV-A16, CV-A6, EV-A71, CV-A10 and other enteroviruses.

Spatiotemporal predictions of obesity prevalence in Chinese children and adolescents: based on analyses of obesogenic environmental variability and Bayesian model. Int J Obes (Lond) 2019; 43:1380-1390. [PMID: 30568273 PMCID: PMC6584073 DOI: 10.1038/s41366-018-0301-0] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/08/2018] [Revised: 11/03/2018] [Accepted: 11/30/2018] [Indexed: 01/22/2023]
Abstract
OBJECTIVE To find variations in Chinese obesogenic environmental priorities from 2000 to 2011, predict spatiotemporal distribution of obesity prevalence aged 7-17 years in 31 provinces, and provide foundations for policy-makers to reduce obesity in children and adolescents. METHODS Based on data examination of provincial obesity prevalence aged 7-17 years from three rounds of China Health and Nutrition Surveys (in 9 [2000], 9 [2006], and 12 [2011] provinces) and corresponding years' environments in 31 provinces from China Statistical Yearbooks and other sources, 12 predictors were selected. We used 30 surveyed provinces in three rounds as training samples to fit three analytic models with partial least-square regressions and prioritized predictors by variable importance projection to find variations. And fitted a spatiotemporal prediction model with Bayesian analysis to infer in space-time. RESULTS Variations of obesogenic environmental priorities were found at different times. A Bayesian spatiotemporal prediction model with deviance information criterion of 155.60 and statistically significant (P < 0.05) parameter estimates of intercept (-717.0400, 95% confidence intervals [CI]: -1186.0300, -248.0480), year (0.3584, CI: 0.1245, 0.5924), square of food industry level (0.0003, CI: 0.0002, 0.0004), and log (healthcare) (5.3742, CI: 2.5138, 8.2347) was optimized. Totally inferred average obesity prevalence among children and adolescents were 2.23%, 5.11%, 10.77%, 12.20%, 13.99%, and 17.58% in 31 provinces in China in 2000, 2006, 2011, 2015, 2020, and 2030, respectively. Obesity in north and east of China clusters on predicted maps. CONCLUSIONS Obesity prevalence in children and adolescents in China is rapidly increasing, growing at 0.3584% annually from 2000 to 2011. From longitudinal observation, prevalence was significantly influenced by food industry ("Amplifier") and healthcare service ("Balancer"). Targeted interventions in north and east of China are pressing. Further researches on the mechanisms underlying the influence of food industry, healthcare service, and so on in children and adolescents are needed.

Abstract
One of the most ubiquitous techniques within attosecond science is the so-called reconstruction of attosecond beating by interference of two-photon transitions (RABBIT). Originally proposed for the characterization of attosecond pulses, it has been successfully applied to the accurate determination of time delays in photoemission. Here, we examine in detail, using numerical simulations, the effect of the spatial and temporal properties of the light fields and of the experimental procedure on the accuracy of the method. This allows us to identify the necessary conditions to achieve the best temporal precision in RABBIT measurements. This article is part of the theme issue 'Measurement of ultrafast electronic and structural dynamics with X-rays'.

Abstract
Objective: To investigate the short-term outcome of patients with acute myocardial infarction complicating cardiogenic shock due to left main disease. Methods: A total of 24 patients with acute myocardial infarction complicating cardiogenic shock due to left main artery disease hospitalized in Fuwai hospital from June 2012 to May 2018 were included. The clinical data were analyzed,and the patients were divided into survivor group (11 cases) and death group (13 cases) according to survival status at 28 days post the diagnosis of shock. The patients were further divided into thrombolysis in myocardial infarction(TIMI) flow grade 0-2 group (11 cases) and TIMI flow grade 3 group (13 cases) according to TIMI flow grade after the procedure. The patients were then divided into non-three-vessel lesions group (14 cases) and three-vessel lesions group (10 cases) according to coronary angiography results. Results: Compared with survivor group, patients in death group presented with lower worst systolic blood pressure within 24 hours after admission (50(48, 70) mmHg (1 mmHg=0.133 kPa) vs. 73(70, 80) mmHg, P<0.01), lower worst diastolic blood pressure with in 24 hours after admission ((33.5±12.4) mmHg vs. (48.9±9.4) mmHg, P<0.01), higher respiratory rates ((27.3±2.5) times/min vs. (21.5±4.0) times/min, P<0.01), less 24 hours urine output ((422±266) ml vs. (1 680±863) ml, P<0.01), lower platelet counts ((161.9±81.9)×10(9)/L vs. (241.6±94.0)×10(9)/L, P=0.03), higher serum creatinine ((250.0±36.8) μmol/L vs. (132.7±34.2) μmol/L, P<0.01), higher alanine aminotransferase (288(76,846) IU/ml vs. 81(42, 109) IU/ml, P=0.04), lower artery pH (7.11±0.17 vs. 7.39±0.09, P<0.01), higher lactic acid ((10.29±3.62) mmol/L vs. (4.21±2.85) mmol/L, P<0.01), higher incidence of invasive ventilation (7/13 vs. 2/11, P=0.02), higher scores of acute physiology and chronic health evaluation (APACHE) Ⅱ (35.4±6.8 vs. 18.7±1.7, P<0.01) and simplified acute physiology score (SAPS) Ⅱ (73.5±17.4 vs. 47.0±4.3, P<0.01), and higher incidence of target vessel TIMI flow grade 0-2 (10/13 vs. 1/11, P<0.01). Kaplan-Meier survival curve analysis showed that survival rate at 28 days post the diagnosis of shock in TIMI flow grade 3 group was higher than that in TIMI flow grade 0-2 group (76.9% vs. 9.1%, log-rank test, P<0.01), and mortality rate was similar at 28 days post the diagnosis of shock between non-three-vessel lesions group and three-vessel lesions group (35.7% vs. 60.0%, log-rank test, P=0.14). Multivariate logistic regression analysis showed that compared with TIMI flow grade 0-2 group, the OR value of death at 28 days post the diagnosis of shock in TIMI flow grade 3 patients with acute myocardial infarction complicating cardiogenic shock due to left main disease was 0.030(95%CI 0.003-0.340, P<0.01). Conclusion: Short-term outcomeof patients with acute myocardial infarction complicating cardiogenic shock due to left main disease remains poor, and final flow of TIMI grade 3 is confirmed as independent protective factor of death at 28 days post the diagnosis of shock in these patients.

Abstract
OBJECTIVES Internet-based venue sex-seeking is prevalent among money boys (MBs), as is a high degree of mobility, which is crucial for HIV transmission in key populations with high risks of HIV infection. However, correlation studies in MBs are scarce because of the secretive nature of this hard-to-reach subpopulation. We conducted this project to explore the characteristics of MBs. METHODS This survey was conducted from December 2014 to June 2015 in Tianjin; a total of 330 MBs were recruited by convenience sampling. Demographic and behavioural data were collected for analysis. RESULTS Among the investigated MBs, 38 (11.52%) were HIV positive, 147 (44.55%) reported using internet-based venues to seek sexual partners and 257 (77.88%) had travelled to two or more destinations in the past 6 months. Compared with non-internet-based venue-using MBs, internet-based venue-using MBs were more likely to have part-time employment as MBs, to have a longer duration of working in the sex trade, to engage in finger intercourse and to present a history of substance abuse and sexually transmitted infections. However, internet-based venue-using MBs were less likely to exhibit consistent condom usage and undergo HIV testing. Origin of residence data showed that most MBs were from northern China, with Tianjin, Beijing and Shanghai as the main travel destinations. Mobile MBs were characterized as a group who were fully engaged in the sex trade and frequently took part in sexual activities but had a weak sense of self-protection. CONCLUSIONS Internet-based venue sex-seeking and mobility are prevalent in MBs. Renewed efforts in internet-based health promotion and school-based primary health examination programmes may benefit more mobile and/or internet-based venue sex-seeking MBs.

Abstract
In this paper, we report a 3.7 kW all fiber narrow linewidth single mode fiber laser. The full width at half-maximum is about 0.30 nm, and the beam quality is Mx2=1.358, My2=1.202 at maximum output power. The laser is achieved by simultaneously suppressing nonlinear effects and mode instability (MI). Different seeds are injected into the main amplifier to study stimulated Raman scattering (SRS) effect. The results show that the phase modulated single frequency seed is benefit to suppress the SRS effect. For the phase modulated single frequency seed, inserting a filter in preamplifier will suppress amplified spontaneous emission (ASE) and decrease the backward power. By optimizing the coiling of active fiber, the MI effect is suppressed.

Abstract
Abstract
TP53 is a well-known tumor suppressor gene and mutations in TP53 are the most frequent genomic event in most cancers including breast cancer. Recent studies have shown that the frequency, spectrum, timing, and clinical implications of TP53 mutations varied in different molecular subtypes of breast cancer. For example, the frequency of TP53 mutations is the highest in basal-like subtype and lowest in luminal A tumors. However, the evaluation of TP53 protein expression, as a surrogate for TP53 mutations, in large studies in the context of tumor subtypes is limited. In addition, the etiologic relevance of TP53 expression is yet to be investigated. The goal of this study is to evaluate the association of clinical and breast cancer risk factors with TP53 expression, measured using immunohistochemistry (IHC), in breast cancer molecular subtypes. The analysis included 7,226 women with invasive breast cancer who were diagnosed and treated in a tertiary hospital in Beijing, China. Subtypes were defined as Luminal A: ER+ and PR+, HER2–, and low grade (grades 1 or 2); luminal B/HER2–: ER+ and/or PR+, HER2–, and high grade (grade 3); luminal B/HER2+: ER+ and/or PR+, HER2+ (regardless of grade); HER2-enriched: ER–, PR–, and HER2+; Triple-negative (TN): ER–, PR–, and HER2–. As expected, positive TP53 staining showed the lowest frequency in the luminal A (46%) and highest in the TN (61%) and HER2-enriched (63%) subtypes (P-value <0.001). Overall and particularly in luminal A patients, positive TP53 staining was associated with higher frequencies of aggressive tumor features such as higher grade, larger tumor size, higher proliferative index, and EGFR expression. Compared with TP53– patients, TP53+ patients were more likely to have younger ages at onset and increased parity, but these associations were largely driven by the luminal A subtype [OR (95% CI) vs nulliparity = 2.67 (1.59, 4.51); 2.63 (1.52, 4.55); 3.68 (2.01, 6.72) for 1, 2, and ≥3 children, respectively (P-trend = 0.006)]. Luminal A/TP53+ patients were also more likely to have breastfed [OR (95% CI) ever vs never = 1.38 (1.03, 1.85)] than luminal A/TP53– patients. These findings suggest that TP53 IHC staining might be used to further refine the classification of luminal A breast cancer into subgroups with distinct clinical and etiologic relevance.

Abstract
AIMS Bacterial microbiome on grape berry surface may play an important role in grape quality and health. This study aims to investigate the impact of grape varieties and clones on grape berry surface bacterial microbiome from the same vineyard. METHODS AND RESULTS High-throughput sequencing strategy was used to investigate the bacterial diversity and abundance on the grape surfaces of 12 clones belonging to six varieties grown in the same vineyard of Zhengzhou Fruit Research Institute in Henan Province. In total, 45 bacterial phyla and 933 genera were detected from all samples. Cyanobacteria, Proteobacteria and Firmicutes were the most abundant and prevalent phyla, while Bacteroidetes, Chloroflexi, Acidobacteria and Planctomycetes were grape clone specific phyla. The nonrank genus from phylum Cyanobacteria occupied 30-81% of grape clones from Italian Riesling (GRX), Cabernet Franc (PLZ), Pinot Blanc (BBN) and Riesling (LSL). Interestingly, Bacillus, Pseudomonas and Lactococcus were the only three prevalent genera found on all the clones. Furthermore, the predicted functional activities of grape surface bacterial communities varied according to the clones. CONCLUSIONS The present study revealed that in addition to the grape varieties, the variations in grape clone background may also affect the bacterial microbiome on grape surfaces which may ultimately determine their functional activities. SIGNIFICANCE AND IMPACT OF THE STUDY This research provides an important information for grape planting and wine fermentation that not only the grape varieties need to be paid attention but also grape clones from the specific variety need to be concerned.

Abstract
Nucleotide-binding, oligomerization domain (NOD)-like receptor family, pyrin domain containing 3 (NLRP3) gene polymorphism was reported to be associated with susceptibility, disease activity or anti-tumour necrosis factor (TNF) treatment response in rheumatoid arthritis (RA). However, the roles of NLRP3 inflammasome in the development of RA have not yet been elucidated fully. The present study aimed to study the role of NLRP3 inflammasome in RA. NLRP3 inflammasome activation in synovial tissues from RA and osteoarthritis (OA) patients were assessed by Western blot. Active caspase-1 in synovia was stained by a FAM-FLICA caspase-1 probe. Mice with collagen-induced arthritis (CIA) were treated with MCC950, a selective NLRP3 inhibitor, or vehicle for 2 weeks. The clinical score of arthritis, synovial inflammation and cartilage erosion were assessed. Proinflammatory cytokines were measured by enzyme-linked immunosorbent assay (ELISA). The results showed that NLRP3 inflammasome was highly activated in both synovia from RA patients and CIA mice. Activation of NLRP3 inflammasome occurred mainly in the infiltrating monocyte/macrophages in synovia, but not in fibroblast-like synoviocytes. Treatment with MCC950 resulted in significantly less severe joints inflammation and bone destruction. NLRP3 inflammasome activation in the synovia was inhibited significantly by MCC950 with reduced production of interleukin (IL)-1β. The inhibition of NLRP3 inflammasome activation by MCC950 was confirmed further in a human monocytic cell line, THP-1. In conclusion, NLRP3 inflammasome is involved in the pathogenesis of RA. Targeting NLRP3 inflammasome with a small molecule inhibitor might be a novel therapeutic strategy for RA.
