BACKGROUND The optimal radiation field of chemoradiation therapy (CRT) for stage I esophageal squamous cell carcinoma (ESCC) is unknown. This retrospective study compared efficacy and safety of two CRT modalities, involved field irradiation (IFI) and elective nodal irradiation (ENI), when treating patients with clinical stage I (T1bN0M0) ESCC. METHODS Patients had received 60 Gy CRT concurrently with 5-FU and cisplatin between January 2000 and December 2012. Cisplatinum The clinical target volume of IFI was limited to the primary tumor plus a 2-cm craniocaudal margin; that of ENI covered the primary tumor plus the field of regional lymph nodes. RESULTS One hundred and ninety-five patients were selected (IFI group, 78; ENI group, 117). The 5-year overall, cause-specific and progression-free survival rates were 90.5%, 91.6% and 77.6% in the IFI group, and 72.5%, 88.3%, 57.9% in the ENI group, respectively. Of recurrent patients (n = 16 in the IF and n = 33 in the ENI groups) after achieving complete remission, 12 (75%) in the IFI group received definitive salvage therapy, 11 (33%) patients did in the ENI group. More patients died of diseases other than esophageal cancer in the ENI group (n = 29, 25%) than in the IFI group (n = 3, 3.8%). Multivariate analysis identified ENI (HR 3.63 [1.78-7.38], p  less then  0.001), age ≥ 70 (HR 2.65 [1.53-4.58], p  less then  0.001) and PS = 1 (HR 2.36 [1.33-4.18], p = 0.003) as poor prognostic factors for OS. link2 CONCLUSIONS IF irradiation would be better than ENI for the patients with stage I ESCC who received definitive chemoradiotherapy.BACKGROUND The proportion of non-regularly employed persons has increased in Japan, but few studies have examined the relationship between employment status and lung cancer screening (LCS) participation. METHODS Authors analyzed data from the 2010 Comprehensive Survey of Living Conditions in Japan. The anonymous responses of 28,951 people aged 40-69 years old were analyzed. Authors defined nine employment status categories unemployed, regularly employed in a large-, middle-, and small-scale company, non-regularly employed in a large-, middle-, and small-scale company, self-employed, and other. LCS participation in the past year was surveyed through a self-reported questionnaire. Sex-specific prevalence ratios (PRs) and 95% confidence intervals (CIs) for LCS participation for all employment status categories, using the regularly employed in a middle-scale company category as the reference, were calculated using multivariable Poisson regression analysis, after adjusting for potentially confounding factors. RESULTS Multivariable-adjusted PRs (95% CI) for LCS participation for the regularly employed in a large-scale company were 1.33 (1.25-1.41) in men and 1.53 (1.38-1.71) in women. Multivariable-adjusted PRs (95% CI) for LCS participation for the non-regularly employed in a middle- and small-scale company compared with the regularly employed in a middle-scale company were 0.81 (0.72-0.92) and 0.62 (0.50-0.76) in men, and 0.89 (0.80-0.99) and 0.80 (0.71-0.91) in women, respectively. CONCLUSION Regularly employed in a large-scale company had significantly higher LCS participation, and non-regularly employed in a middle- or small-scale company showed significantly lower LCS participation than those who were regularly employed in a middle-scale company.Breast cancer (BC) is a common clinical disease and the second leading cause of cancer death in women. Long noncoding RNA (lncRNA) and microRNA (miRNA) are reported to be involved in the development of BC. The present study aimed to investigate whether LncRNA ZFAS1 could regulate the proliferation, invasion and migration of breast cancer cells by targeting miR-589 through PTEN/PI3K/AKT signal pathway. The expression of ZFAS1 and miR-589 in BC cells and transfection effects were determined by RT-qPCR analysis. The abilities of proliferation, colony formation, invasion and migration of breast cancer cells were analyzed by CCK-8 assay, colony formation assay, transwell assay and wound healing assay respectively. The expression of MMP2, MMP9, Bcl2, Bax, cleaved caspase3, PTEN, p-PI3K, p-AKT, PI3K and AKT was detected by Western blot. The flow cytometry analysis was used to detect cell apoptosis. As a result, ZFAS1 expression was increased and miR-589 expression was decreased in BC cells. And, miR-589 was demonstrated to be a target of ZFAS1. ZFAS1 overexpression could inhibit the proliferation, colony formation, invasion and migration of BC cells while miR-589 overexpression could reverse the changes. In addition, ZFAS1 overexpression suppressed the expression of PI3K/AKT signal pathway by activating the PTEN expression while miR-589 overexpression could reverse the changes. Moreover, PTEN is one of the gene targets of miR-589. In conclusion, this study indicated that ZFAS1 inhibited the proliferation, invasion and migration of breast cancer cells by targeting miR-589 through regulating the PTEN/PI3K/AKT signal pathway.INTRODUCTION The use of 2D NMR data sources (COSY in this paper) allows to reach general metabolomics results which are at least as good as the results obtained with 1D NMR data, and this with a less advanced and less complex level of pre-processing. But a major issue still exists and can largely slow down a generalized use of 2D data sources in metabolomics the experiment duration. OBJECTIVE The goal of this paper is to overcome the experiment duration issue in our recently published MIC strategy by considering faster 2D COSY acquisition techniques a conventional COSY with a reduced number of transients and the use of the Non-Uniform Sampling (NUS) method. These faster alternatives are all submitted to novel 2D pre-processing workflows and to Metabolomic Informative Content analyses. Eventually, results are compared to those obtained with conventional COSY spectra. METHODS To pre-process the 2D data sources, the Global Peak List (GPL) workflow and the Vectorization workflow are used. To compare this data sources and to detect the more informative one(s), MIC (Metabolomic Informative Content) indexes are used, based on clustering and inertia measures of quality. RESULTS Results are discussed according to a multi-factor experimental design (which is unsupervised and based on human urine samples). Descriptive PCA results and MIC indexes are shown, leading to the direct and objective comparison of the different data sets. CONCLUSION In conclusion, it is demonstrated that conventional COSY spectra recorded with only one transient per increment and COSY spectra recorded with 50% of non-uniform sampling provide very similar MIC results as the initial COSY recorded with four transients, but in a much shorter time. Consequently, using techniques like the reduction of the number of transients or NUS can really open the door to a potential high-throughput use of 2D COSY spectra in metabolomics.INTRODUCTION [18F]AmBF3-TATE is a somatostatin agonist that selectively binds to somatostatin receptor subtype 2 (SSTR2). link3 For clinical translation, pharmacokinetics, radiation dosimetry, and acute toxicity of [18F]AmBF3-TATE were assessed with good laboratory practice (GLP) standards. METHODS ICR mice were intravenously administered 0.8-2.0 MBq of [18F]AmBF3-TATE, with one group pre-injected with 100 μg of [19F]AmBF3-TATE 30 min before radiopharmaceutical administration to assess uptake specificity. The mice were euthanized at 0.5, 1, 2, or 4 h post-injection (p.i.). Blood and tissues were collected, weighed, and counted on a gamma counter to determine percentage injected dose per gram (%ID/g). Dosimetry was calculated based on biodistribution data using the mouse and human phantoms included in OLINDA. Acute toxicity was assessed in Sprague-Dawley rats at the dose of 0.742 mg/kg [19F]AmBF3-TATE, with a 14-day observation/recovery period. Blood chemistry parameters, gross, and histopathology were evaluated. Bo GBq, average molar activity of 435 ± 162 GBq/μmol, and radiochemical purity of 98.0 ± 1.73% with the automated synthesizer. CONCLUSION [18F]AmBF3-TATE binds specifically to SSTR2. At 1000× clinical dose, [19F]AmBF3-TATE was well tolerated with no treatment-related adverse effects.OBJECTIVES Our aim was to investigate the prevalence value of a high-avidity antinuclear antibody (ANA) of the IgG isotype (HA IgG ANA) compared with that of ANAs of other isotypes in patients with systemic lupus erythematosus (SLE) and to assess the associations of HA IgG ANA with the activity of SLE and lupus nephritis. METHODS We retrospectively analyzed clinical and laboratory data from subjects. Blood samples were acquired from 101 SLE patients, 67 patients with other autoimmune diseases, and 65 healthy donors. The levels of HA IgG ANA and other isotype ANAs were measured by indirect immunofluorescence (IIF). The prevalence and diagnosis value of HA IgG ANA and other antibodies in SLE patient were tested. The advantage of HA IgG ANA compared with HA anti-dsDNA antibodies IgG (HA dsDNA IgG) was verified by ELISA. We monitored the relative avidity indexes (RAIs) of HA IgG ANA and HA dsDNA IgG at 3 time points after the start of treatment in the same individuals with SLE. RESULTS The prevalence of HA IgG ANIgG ANA (HA IgG ANA)" that could distinguish between the early stage of SLE and SLE that had been active for some time.• The relative avidity indexes (RAIs) of HA IgG ANA and HA dsDNAIgG were presented and applied here to evaluate the avidities of antibodies involved in SLE.• In our study, we confirmed the value of HA IgG ANA in diagnosing SLE. In addition, HA IgG ANA was more appropriate for identifying the activity of SLE than was HA dsDNA IgG.• In conclusion, HA IgG ANA could be a potential biomarker for the assessment of the prognosis of SLE activity.INTRODUCTION Biologic disease-modifying antirheumatic drugs (bDMARDs) play a pivotal role in the treatment of psoriatic arthritis (PsA). Despite this, their discontinuation due to inefficacy or adverse events is often observed. The aims of this study are to describe retention rates and treatment trends of anti-TNFα, anti-IL17, and anti-IL12/23R agents in patients with PsA and to identify factors associated with bDMARDs discontinuation in a real-world clinical setting. METHODS A retrospective cohort study based on the analysis of the three Italian prescription cohorts of patients with PsA has been performed. Survival analysis was performed using Kaplan-Meier curves and Cox proportional-hazards model. RESULTS During the follow up, which lasted 25.5 (12-60) months, 68 patients discontinued a bDMARD 13 for primary failure, 12 for secondary failure, 15 for adverse events, 5 for remission, 12 because of lost at follow-up, and 11 for other causes. Cox proportional-hazards demonstrated that a shorter disease duration (HR 0.994991, 95% CI 0.9910336-0.9989647, p = 0.014) and first-line bDMARD (HR 0.5090986, 95% CI 0.3073519-0.8432722, p = 0.009) have a protective role on bDMARD retention rate, while the multivariable analysis failed in demonstrating an independent protective role of male sex on drug retention rate (p = 0.083). No significant differences in retention rate have been found regarding biologic drugs, combination therapy or monotherapy, and class of bDMARD (anti-TNFα or anti-pIL12/23R and anti-IL-17). CONCLUSIONS This study shows that a shorter disease duration and treatment with a first-line bDMARD are predictors of bDMARDs retention rate, further highlighting the importance of early diagnosis of PsA.Key Points• No significant difference in retention among patients treated with anti-IL17A, anti-IL12/23R, and anti-TNFα agents has been demonstrated.• A shorter disease duration and first-line bDMARD treatment are associated with persistence in biologic treatment.
