    Previous studies indicate a possible inverse relationship between prostate-specific antigen (PSA) and body mass index (BMI), and a positive relationship between PSA and age. We investigated the associations between age, BMI, PSA, and screen-detected prostate cancer to determine whether an age-BMI-adjusted PSA model would be clinically useful for detecting prostate cancer. Cross-sectional analysis nested within the UK ProtecT trial of treatments for localized cancer. Of 18,238 men aged 50-69 years, 9,457 men without screen-detected prostate cancer (controls) and 1,836 men with prostate cancer (cases) met inclusion criteria: no history of prostate cancer or diabetes; PSA BMI between 15 and 50 kg/m(2). Multivariable linear regression models were used to investigate the relationship between log-PSA, age, and BMI in all men, controlling for prostate cancer status. In the 11,293 included men, the median PSA was 1.2 ng/ml (IQR: 0.7-2.6); mean age 61.7 years (SD 4.9); and mean BMI 26.8 kg/m(2) (SD 3.7). There were a 5.1% decrease in PSA per 5 kg/m(2) increase in BMI (95% CI 3.4-6.8) and a 13.6% increase in PSA per 5-year increase in age (95% CI 12.0-15.1). Interaction tests showed no evidence for different associations between age, BMI, and PSA in men above and below 3.0 ng/ml (all p for interaction >0.2). The age-BMI-adjusted PSA model performed as well as an age-adjusted model based on National Institute for Health and Care Excellence (NICE) guidelines at detecting prostate cancer. Age and BMI were associated with small changes in PSA. An age-BMI-adjusted PSA model is no more clinically useful for detecting prostate cancer than current NICE guidelines. Future studies looking at the effect of different variables on PSA, independent of their effect on prostate cancer, may improve the discrimination of PSA for prostate cancer.

    Prostate cancer (PCa) is one of the most common malignancies and main causes of cancer death in Western countries. In the presence of metastatic disease, systemic treatment remains the main clinical option. However, since the introduction of highly sensitive imaging techniques, a new clinical 'entity' of metastatic patients with a limited number of lesions has been defined: oligometastatic patients. In this patient group, the use of stereotactic body radiotherapy (SBRT) or other local therapies against all active sites of disease revealed by 18F-choline positron emission tomography/computed tomography (PET/CT) could achieve sufficient prostate-specific antigen (PSA) control. However, a clear benefit of this procedure in terms of significant endpoints is yet to be demonstrated. This case report describes our experience with treating a castration-resistant PCa patient with 18F-choline PET/CT-guided SBRT. Because of the occurrence of 5 metachronous lesions over 4 years, the pattern of recurrence was defined by the local multidisciplinary team as oligometastatic disease, and the patient was treated with 5 courses of SBRT which yielded good PSA control. He started systemic therapy with abiraterone acetate almost 5 years after the diagnosis of recurrent PCa. © 2016 S. Karger GmbH, Freiburg.

    ESA has established a Planetary Science Archive User Group (PSA-UG), with the task of offering independent advice to ESA's Planetary Science Archive (e.g. Heather et al., 2013). The PSA-UG is an official and independent body that continuously evaluates services and tools provided by the PSA to the community of planetary data scientific users. The group has been tasked with the following top level objectives: a) Advise ESA on future development of the PSA. b) Act as a focus for the interests of the scientific community. c) Act as an advocate for the PSA. d) Monitor the PSA activities. Based on this, the PSA-UG will report through the official ESA channels. Disciplines and subjects represented by PSA-UG members include: Remote Sensing of both Atmosphere and Solid Surfaces, Magnetospheres, Plasmas, Radio Science and Auxilliary data. The composition of the group covers ESA missions populating the PSA both now and in the near future. The first members of the PSA-UG were selected in 2013 and will serve for 3 years, until 2016. The PSA-UG will address the community through workshops, conferences and the internet. Written recommendations will be made to the PSA coordinator, and an annual report on PSA and the PSA-UG activities will be sent to the Solar System Exploration Working Group (SSEWG). Any member of the community and planetary data user can get in touch with individual members of the PSA-UG or with the group as a whole via the contacts provided on the official PSA-UG web-page: http://archives.esac.esa.int/psa/psa-ug.

    Serum prostate-specific antigen (PSA) assays differ in calibration and response to different PSA forms. We examined intermethod differences in total PSA (tPSA) and free PSA (fPSA) measurements. We tested 157 samples with tPSA concentrations of 2 to 10 ng/mL (2-10 microg/L) using 6 PSA/fPSA method pairs and 1 tPSA method: ADVIA Centaur (complexed and total; Siemens Diagnostics, Tarrytown, NY), ARCHITECT i 2000(SR) (Abbott Diagnostics, Abbott Park, IL), AxSYM (Abbott Diagnostics), IMMULITE 2000 (Siemens Diagnostics), Modular E170 (Roche Diagnostics, Indianapolis, IN), UniCel DxI 800 (Beckman Coulter, Brea, CA), and VITROS ECi (tPSA only; Ortho-Clinical Diagnostics, Raritan, NJ). Regression analysis was performed for PSA, fPSA, and percentage of fPSA with the ARCHITECT i 2000(SR) comparison method. Differences between test and comparison methods were estimated at 2.5, 4.0, and 10.0 ng/mL (2.5, 4.0, and 10.0 microg/L) for tPSA and 15%, 20%, and 25% for percentage of fPSA. Relative differences were more than 10% at 4.0 ng/mL (4.0 microg/L) tPSA for the Centaur, IMMULITE, ECi, and DxI methods. At 20% fPSA, the relative difference was more than 10% for all methods except the AxSYM. Additional harmonization is needed for tPSA and fPSA methods.

    Full Text Available The EU decision-making system is a unique combination of the power of the states and supranational institutions. The relationship between the institutions and the states allows us to establish several competing theoretical explanations while trying to describe and explain this mutual relationship. One of the most influential theoretical explanations is the institutionalism of rational choice and the associated principal – agent model. This article is based on the analysis of the youngest EU advisory body, the Committee of the Regions (CoR. The article examines the evolution of the relationship between principal (Member states and agent (CoR and the trend that can be observed in this process.

    2006-02-01

    To analyze prostate-specific antigen (PSA) kinetics in patients treated with prostate brachytherapy (PI) with a minimum of 5 years of PSA follow-up. The records of 162 patients treated with PI for localized prostate cancer with a minimum of 5 years of PSA follow-up were reviewed. A variety of pretreatment and posttreatment variables were examined. Patients were coded as having a PSA bounce if their PSA achieved a nadir, elevated at least 0.2 ng/mL greater than that nadir, and decreased to, or below, the initial nadir. Two definitions of biochemical failure (bF) or biochemical relapse-free survival (bRFS) were used: the classic American Society for Therapeutic Radiology and Oncology consensus definition of three consecutive rises (bF3) and the nadir plus 2 ng/mL definition (bFn+2). Associations between a PSA bounce and the various pre- and posttreatment factors were assessed with logistic regression analysis, and the association between a PSA bounce and bF was examined with the log-rank test. The Mann-Whitney U test was applied to test for differences in the PSA doubling time (PSADT) and the time to a PSA rise between the PSA bounce patients and the bF patients. PSADT was calculated from the nadir to the time of the first PSA rise, because this point is known first in the clinical setting. The 5-year overall bRFS rate was 87% for the bF3 definition and 96% for the bFn+2 definition. A PSA bounce was experienced by 75 patients (46.3%). Patients who experienced a PSA bounce were less likely to have a bF, regardless of the bRFS definition used (bF3: p=0.0015; bFn+2: p=0.0040). Among the pre- and posttreatment factors, only younger age predicted for a PSA bounce on multivariate analysis (p=0.0018). The use of androgen deprivation had no effect on PSA bounce. No difference was found in the PSADT between patients who had a PSA bounce and those with bF. The median PSADT for those with a PSA bounce was 8.3 months vs. 10.3 months using the bF3 definition and 8.8 months using

    2018-02-17

    To provide a mathematical background for understanding the phenomenon of analyte hemodilution using a kinetic analysis. The first assumption for this analysis is that change in concentration of any analyte, such as prostate-specific antigen (PSA), is due to the flux of the analyte from an organ into the blood minus its flux from the blood. What results is a relatively simple differential equation that emphasizes the importance of plasma volume, organ mass, and two rate constants. The analyses demonstrate how serum PSA can be affected by plasma volume as well as body mass and how hemodilution due to obesity can be at least partly corrected for by expressing PSA in units of total mass or total mass density. At a time when obesity is prevalent, expressing analytes in units of total mass may make them relate more closely to disease status and prognosis.

    Now a days measurement of molecular forms of PSA has gained importance in clinical practice. Several studies have demonstrated the production of PSA in female tissues, such as breast. The present piece of work has been undertaken with an objective to estimate the relative proportion of the molecular forms of PSA in serum along with serum testosterone in benign and malignant breast tumor cases and to analyze their association with the severity of the disease process 34 malignant and 26 benign breast disease cases along with 33 healthy controls of same age group were enrolled in this study for evaluation. Serum testosterone was measured by ELISA, whereas serum total PSA (TPSA) and free PSA (FPSA) were estimated by electrochemiluminescence immunoassay. A significant rise of fasting plasma glucose along with prominent dyslipidemia was observed in breast tumor cases. Marked rise in serum testosterone as well as TPSA and FPSA was documented in both benign and malignant breast tumor cases. Serum testosterone revealed a significant positive association with both TPSA and FPSA pointing towards an etiological association between them. However, surgical removal of tumor mass resulted in a marked decline of presurgical value of both TPSA and FPSA with a non-significant fall in serum testosterone revealing tumor tissue as the source of FPSA and TPSA. Thus, estimation of PSA provides prognostic information that may assist in future treatment.

    Polycystic ovarian syndrome (PCOS) is a common cause of reproductive and metabolic dysfunction. We hypothesized that serum prostate-specific antigen (PSA) may constitute a new biomarker for hyperandrogenism in PCOS. We conducted a cross-sectional study of 45 women with PCOS and 40 controls. Serum from these women was analyzed for androgenic steroids and for complexed PSA (cPSA) and free PSA (fPSA) with a novel fifth- generation assay with a sensitivity of ~10 fg/mL for cPSA and 140 fg/mL for fPSA. cPSA and fPSA levels were about three times higher in PCOS compared to controls. However, in PCOS, cPSA and fPSA did not differ according to waist-to-hip ratio, Ferriman-Gallwey score, or degree of hyperandrogenemia or oligo-ovulation. In PCOS and control women, serum cPSA and fPSA levels were highly correlated with each other, and with free and total testosterone levels, but not with other hormones. Adjusting for age, body mass index (BMI) and race, cPSA was significantly associated with PCOS, with an odds ratio (OR) of 5.67 (95% confidence interval [CI]: 1.86, 22.0). The OR of PCOS for fPSA was 7.04 (95% CI: 1.65, 40.4). A multivariate model that included age, BMI, race and cPSA yielded an area-under-the-receiver-operating-characteristic curve of 0.89. Serum cPSA and fPSA are novel biomarkers for hyperandrogenism in PCOS and may have value for disease diagnosis.

    Over the last years numerous semiquantitative PSA tests have appeared, based on serum or plasma immunochromatography. We present our experience using the SD BIOLINE PSA test, which is performed with plasma or serum for fast qualitative determination of PSA; the cutpoint is 3 ng/ml. We analized 54 patients who were admitted in our hospital ward. Two blood samples were obtained from every patient, one for cuantitative PSA determination at the hospital laboratory and the other one for qualitative determination with the SD BIOLINE PSA test, and the results were compared.. Two urologists independently interpreted the test without knowing the PSA values from the lab. To calculate the effect of test reading time, readings were performed at 15, 20 and 25 minutes. Results were classified in a classic contingency table, which enabled us to calculate sensitivity and specificity of the test, as well as positive and negative predictive values. Mean age was 71. 1 years (range 43-96 yr). From 54 patients in the study 26 (48. 14%) had a PSA > 3 ng/ml (Mean 18.5 ng/ml, range 3.9-66.9 ng/ml) and 28 (51.86%) PSA < 3 ng/ml (mean 0.8 ng/mL, range 0-2.9 ng/mL), in the conventional test. Results for each interval and observer were: 15 min: Observer 1: Sensitivity (S) 76,92%, specificity (E) 100%, positive predictive value (PPV) 100%, negative predictive value (NPV) 82.35%; Observer 2: S 76.92%, E 100%, PPV 100%, NPV 82.35%. 20 minutes: Observer 1: S 100%, E 93.33%, PPV 92.30%, NPV 100%; Observer 2: S 100%, E 93.33%, PPV 92.30%, NPV 100%. 25 minutes: Observer 1: S 100%, E 85.71%, PPV 86.66%, NPV 100%; Observer 2: S 92.30%, E 92.85%, PPV 92.30%, NPV 92.85%. The SD Bioline PSA test complies with the characteristics required to be used as a test for prostate cancer detection, it is simple, fast, cheap, not much invasive, and has a good efficacy.

    To examine the effectiveness of serum free-to-total prostate specific antigen ratio (%fPSA) for the detection of prostate cancer (PCa) in men with different serum total PSA (tPSA) categories. From January 2010 to December 2013, a total of 225 patients with lower urinary tract symptoms (LUTS) underwent tPSA and %fPSA measurements. Histological examination with calculation of Gleason score and whole body bone scans were performed in identified cases of PCa. PCa was diagnosed in 44 (19.6%) patients and the remaining 181 patients had benign prostate disease. PCa was detected in 5 (23.8%), 13 (8.7%) and 26 (47.3%) cases with tPSA level ranges≤4 ng/ml, 4 to 10 ng/ml and >10 ng/ml, respectively. The average Gleason score was 7.2±0.2. Some 6 (13.6%) out of 44 PCa patients had bone metastases. The sensitivity was 80% and specificity was 81.3% at the cut-off %fPSA of 15% in PCa patients with a tPSA level below 4 ng/ mL. A lower %fPSA was associated with PCa patients with Gleason score≥7 than those with Gleason score≤6 (11.7±0.98 vs. 16.5±2.25%, P=0.029). No obvious relation of %fPSA to the incidence of bone metastasis was apparent in this study. The clinical application of %fPSA could help to discriminate PCa from benign prostate disease in men with a tPSA concentration below 4 ng/mL.

    Full Text Available Guided by the methodological perspective of analytical deconstruction, this work analyses photographic images from Maringa´s Prefecture press advisory. It seeks to answer to the following question: What strategies of senses do the photographic images build in the press advisement? In this attempt, it aims to: 1 To conceptualize the aspect of communicational intentionality; 2 To infer about its use on press advisory services; 3 To analyze if formats and genres of photographic image in journalism remain in the press advisory body. As a discourse, the photographic image in the press advisory body aims to build positive senses for the advised. In this case, with technical and photographic language domain, photojournalists intent to build elements, objects and characters to build up concepts, values and positive representation of the advised. For analysis of the photojournalists’ intentionality, they were used photographs taken from the site of the press advisory body of Maringá (PR Prefecture, referring to several articles.

    In general, Probabilistic Safety Agreement (PSA) is a very complicated work that uses and generates a lot of resources such as reports, procedures, drawings, assumptions, calculation sheets, PSA model, and so on. In many PSAs, however, the data, materials and knowledge considered and generated during performing PSA are scattered in many documents so that overall structure of PSA and information relationship between documents and models cannot easily be understood. To organize and manage all documents related to PSA, to capture knowledge of analysts, and finally to improve the quality of PSA, a PSA information management system (PIMS) was developed. The PIMS can manage all the documents of a PSA in a database and connect the causal relation between one information to another in the scattered documents via link. The PIMS can manage all the assumptions and technical basis used in PSA, and it can keep the record of the design changes the revision of PSA model. It can also control the review results of PSA models. The link of the PIMS can explicitly describe and reveal the expertise of the PSA analysts, and it enables the users to capture the knowledge and to understand the structure and contents of a PSA with ease. We are planning to apply the PIMS to the PSA of Shin Kori Units 1 and 2 as feasibility study and then to all the PSAs of the nuclear power plants in Korea. The PIMS is expected to contribute to enhancing the quality and confidence of PSA and reducing the efforts and costs of maintenance and update of PSA. (authors)

    The objective of the study was to investigate prostate-specific antigen (PSA) nadir (nPSA) and time to nPSA (TnPSA) as prognostic variables for outcomes after definitive high-dose (>75 Gy) external beam radiation therapy (RT) without androgen deprivation therapy while correcting for immortal-time bias. nPSA and TnPSA were available for 410 patients. nPSA and TnPSA's impact on freedom from biochemical failure, freedom from metastasis, and prostate cancer-specific survival was assessed on univariate and multivariate analysis using Kaplan-Meier and Cox proportional hazards regression. Outcomes were also evaluated relative to the time since achieving nPSA and not relative to the time of RT, given the intrinsic time bias in TnPSA. Median nPSA was 0.7 ng/mL (interquartile range: 0.4 to 1.1), with a median TnPSA of 25.0 months (IQR: 15.0 to 40.0). On univariate analysis both nPSA and TnPSA were predictive of all endpoints: freedom from biochemical failure, freedom from metastasis, and prostate cancer-specific survival, as categorical (all Pimmortal-time bias the benefit of long TnPSA was mostly lost. On Cox proportional hazards, a TnPSA12 months from the time of RT the TnPSA was no longer prognostic. For dose-escalated RT a lower nPSA is prognostic, but the benefit of a long TnPSA is largely an immortal-time bias and that a longer TnPSA is not in and of itself a significant favorable factor except as compared with those with the shortest TnPSA of <12 months.

  9. Review of UCN 5,6 Fire PSA Model based on ANS Fire PRA Standard

    Yang, Joon Eon; Lee, Yoon Hwan

    2006-12-15

    Recently, under the de-regulation environment, nuclear industry has attempted various approaches to improve the economics of Nuclear Power Plants (NPP). This approach uses the fire risk and performance information to manage the resources effectively and efficiently that are used in the operation of NPP. In fire risk informed/performance-based decision/operation, fire PSA quality is one of the most important things. The nuclear industry and regulatory body of U.S.A have developed a measure to evaluate the quality of fire PSA. ANS (American Nuclear Society) has developed a guidance called 'ANS Fire PRA Methodology Standard'. However, in Korea, there have been no attempts to evaluate the quality of fire PSA model itself. Therefore, we cannot be sure about the quality of fire PSA whether or not the present fire PSA model can be used for the risk-informed applications such as mentioned above. We can say that the evaluation of fire PSA model quality is the basis for the fire risk informed/performance-based decision/operation. In this report, we have evaluated the quality of fire PSA model for Ulchin 5 and 6 units based on the ANS Fire PRA Standard. We, also, have derived what items are to be improved to upgrade the quality of fire PSA model and how it can be improved. This report can be used as the base of the fire risk informed/performance-based decision/operation work in Korea.

    2001-11-01

    Along with the adoption of risk informed decision making principles, the need for formal probabilistic decision rule or criteria has been risen. However, there are many practical and theoretical problems in the application of probabilistic criteria. One has to think what is the proper way to apply probabilistic rules together with deterministic ones and how the criteria are weighted with respect to each other. In this report, we approach the above questions from the decision theoretic point of view. We give a short review of the most well known probabilistic criteria, and discuss examples of their use. We present a decision analytic framework for evaluating the criteria, and we analyse how the different criteria behave under incompleteness or uncertainty of the PSA model. As the conclusion of our analysis we give recommendations on the application of the criteria in different decision situations. (au)

    Full Text Available Prostate cancer remains significant public health concern amid growing controversies regarding prostate specific antigen (PSA based screening. The utility of PSA has been brought into question, and alternative measures are investigated to remedy the overdetection of indolent disease and safeguard patients from the potential harms resulting from an elevated PSA. Multiparametric MRI of the prostate has shown promise in identifying patients at risk for clinically significant disease but its role within the current diagnostic and treatment paradigm remains in question. The current review focuses on recent applications of MRI in this pathway.

    Purpose PSA and free PSA (fPSA) have limited specificity for detecting clinically significant, curable prostate cancer (PCa), leading to unnecessary biopsies and detection and treatment of some indolent tumors. [−2]proPSA (p2PSA) may improve specificity for detecting clinically significant PCa. Our objective was to evaluate p2PSA, fPSA, and PSA in a mathematical formula (prostate health index [phi] = [−2]proPSA / fPSA) × PSA1/2) to enhance specificity for detecting overall and high-grade PCa. Materials and Methods We enrolled 892 men in a prospective multi-institutional trial with no history of PCa, normal rectal examination, a PSA of 2–10 ng/mL, and ≥6- core prostate biopsy. We examined the relationship of serum PSA, %fPSA and phi with biopsy results. The primary endpoints were the specificity and AUC using phi to detect overall and Gleason ≥7 prostate cancer on biopsy compared with %fPSA. Results For the 2–10 ng/mL PSA range, at 80–95% sensitivity, the specificity and AUC (0.703) of phi exceeded those of PSA and %fPSA. Increasing phi was associated with a 4.7-fold increased risk of PCa and 1.61-fold increased risk of Gleason ≥7 disease on biopsy. The AUC for phi (0.724) exceeded that of %fPSA (0.670) in discriminating between PCa with Gleason ≥ 4+3 vs. lower grade disease or negative biopsies. Phi results were not associated with age and prostate volume. Conclusions Phi may be useful in PCa screening to reduce unnecessary biopsies in men age ≥50 years with PSA 2–10 ng/mL and negative DRE, with minimal loss in sensitivity. PMID:21419439

    To evaluate the roles of total prostate specific antigen (tPSA), PSA density (PSAD) and biopsy Gleason score in predicting the pathologic stage of prostate cancer. We retrospectively analyzed the clinical data of 124 cases of pathologically confirmed prostate adenocarcinoma, and divided them into Groups A (n=48) and B (n=76) based on the results of bone scanning, CT, MRI, tPSA, PSAD and postoperative biopsy Gleason score, the former with extraprostatic infiltration or distant metastasis, while the latter without. We compared the above parameters between the two groups, screened the main factors that influenced the pathologic staging of prostate cancer by multivariate logistic regression analysis, and appraised the value of each of the parameters in predicting the pathologic stage of prostate cancer with a relative operating characteristic (ROC) curve. The tPSA level and biopsy Gleason score were significantly higher in Group A than in B (P Gleason score had a better predicting value than other parameters (Gleason score + tPSA > tPSA > PSAD + tPSA + Gleason score). Total PSA remains a valuable predictor of the pathologic stage of prostate cancer, and its combination with Gleason score can further improve the predictive accuracy and contribute much to the treatment and prognosis of the disease.

    Prostate cancer (PC) is one of the most common malignancies in male, and has become the fastest growing malignancy in recent years. Prostate specific antigen (PSA) is widely used as a tumor marker to screen for PC. Many studies have been performed to define the reference intervals (RIs) for total circulating PSA (tPSA). The results were different among different nations and races, even in the same race. Few researches have been performed on the RIs of free PSA (fPSA) and the ratio of free to total PSA (%fPSA). In this study, we aimed to simultaneously determine the age-specific RIs for tPSA, fPSA, and %fPSA in the healthy Han ethnic male. A total of 1862 apparently healthy male aged from 21 to 94 years were included in our study. Nonparametric 95th percentile intervals were used to define the RIs. The reference limits in different age groups (21-50, 51-60, 61-70, 71-80, and ≥81 years) were 2.07, 3.59, 4.93, 6.83, and 7.73 ng/mL for tPSA, and 0.60, 0.76, 0.83, 1.30, and 2.41 ng/mL for fPSA. The RIs of %fPSA were ≥0.16 for 21-50 years and ≥0.13 for male over 50 years old. We established age-specific RIs for tPSA, fPSA and %fPSA. The newly established RIs should be more suitable for Chinese Han ethnic male. It will be valuable for physicians to make exact medical decision and appropriate medical intervention. © 2016 Wiley Periodicals, Inc.

    Cellular interactions with the extracellular environment are modulated by cell surface polysialic acid (PSA) carried by the neural cell adhesion molecule (NCAM). PSA-NCAM is involved in cellular processes such as differentiation, plasticity, and migration, and is elevated in Alzheimer's disease as well as in metastatic tumour cells. Our previous work demonstrated that insulin enhances the abundance of cell surface PSA by inhibiting PSA-NCAM endocytosis. In the present study we have identified a mechanism for insulin-dependent inhibition of PSA-NCAM turnover affecting cell migration. Insulin enhanced the phosphorylation of the focal adhesion kinase leading to dissociation of αv-integrin/PSA-NCAM clusters, and promoted cell migration. Our results show that αv-integrin plays a key role in the PSA-NCAM turnover process. αv-integrin knockdown stopped PSA-NCAM from being endocytosed, and αv-integrin/PSA-NCAM clusters co-labelled intracellularly with Rab5, altogether indicating a role for αv-integrin as a carrier for PSA-NCAM during internalisation. Furthermore, inhibition of p-FAK caused dissociation of αv-integrin/PSA-NCAM clusters and counteracted the insulin-induced accumulation of PSA at the cell surface and cell migration was impaired. Our data reveal a functional association between the insulin/p-FAK-dependent regulation of PSA-NCAM turnover and cell migration through the extracellular matrix. Most importantly, they identify a novel mechanism for insulin-stimulated cell migration. - Highlights: • Insulin modulates PSA-NCAM turnover through upregulation of p-FAK. • P-FAK modulates αv-integrin/PSA-NCAM clustering. • αv-integrin acts as a carrier for PSA-NCAM endocytosis. • Cell migration is promoted by cell surface PSA. • Insulin promotes PSA-dependent migration in vitro.

  19. Experience from the comparison of two PSA-studies

    Energy Technology Data Exchange (ETDEWEB)

    2001-03-01

    Two probabilistic safety assessments (PSA) made for nearly identical reactors units (Forsmark 3 and Oskarshamn 3) have been compared. Two different analysis teams made the PSAs, and the analyses became quite different. The goal of the study is to identify, clarify and explain differences between PSA-studies. The purpose is to understand limitations and uncertainties in PSA, to explain reasons for differences between PSA-studies, and to give recommendations for comparison of PSA-studies and for improving the PSA-methodology. The reviews have been made by reading PSA-documentation, using the computer model and interviewing persons involved in the projects. The method and findings have been discussed within the project group. Both the PSA-project and various parts in the PSA-model have been reviewed. A major finding was that the two projects had different purpose and thus had different resources, scope and even methods in their study. The study shows that comparison of PSA results from different plants is normally not meaningful. It takes a very deep knowledge of the PSA studies to make a comparison of the results and usually one has to ensure that the compared studies have the same scope and are based on the same analysis methods. Harmonisation of the PSA-methodology is recommended in the presentation of results, presentation of methods, scope main limitation and assumption, and definitions for end states, initiating events and common cause failures. This would facilitate the comparison of the studies. Methods for validation of PSA for different application areas should be developed. The developed PSA review standards can be applied for a general validation of a study. The most important way to evaluate the real feasibility of PSA can take place only with practical applications. The PSA-documentation and models can be developed to facilitate the communication between PSA-experts and users. In any application consultation with the PSA-expert is however needed. Many

    2016-01-01

    Background The use of biomarkers for prostate cancer screening, diagnosis and prognosis has the potential to improve the clinical management of the patients. Owing to inherent limitations of the biomarker prostate-specific antigen (PSA), intensive efforts are currently directed towards a search for alternative prostate cancer biomarkers, particularly those that can predict disease aggressiveness and drive better treatment decisions. Methods A literature search of Medline articles focused on recent and emerging advances in prostate cancer biomarkers was performed. The most promising biomarkers that have the potential to meet the unmet clinical needs in prostate cancer patient management and/or that are clinically implemented were selected. Conclusions With the advent of advanced genomic and proteomic technologies, we have in recent years seen an enormous spurt in prostate cancer biomarker research with several promising alternative biomarkers being discovered that show an improved sensitivity and specificity over PSA. The new generation of biomarkers can be tested via serum, urine, or tissue-based assays that have either received regulatory approval by the US Food and Drug Administration or are available as Clinical Laboratory Improvement Amendments-based laboratory developed tests. Additional emerging novel biomarkers for prostate cancer, including circulating tumor cells, microRNAs and exosomes, are still in their infancy. Together, these biomarkers provide actionable guidance for prostate cancer risk assessment, and are expected to lead to an era of personalized medicine. PMID:26790878

    Full Text Available Introduction. PSA parameters have been used in an attempt to improve the diagnostic yield of prostate screening tests; the detection of primary malignant circulating prostate cells (CPCs may improve the diagnostic yield of screening and therefore avoid unnecessary biopsies. Patients and Methods. Prospective study of all men undergoing initial prostate biopsy due to an elevated total serum PSA. Free percent PSA, PSA velocity, and PSA density were determined. Primary CPCs were detected using standard immunocytochemistry. A positive test for CPCs was defined as one cell PSA (+ P504S (+ in an 8 ml blood sample. Positive predictive and negative predictive values, specificity, and sensitivity were calculated for each test as well as the number of biopsies avoided and cancers missed. Results. 303 men participated in the study of whom 113/303 (37.3% men had prostate cancer. Of the three PSA based parameters, free percent PSA was superior, sensitivity 70.8%, and specificity 67.4%. Primary CPCs detection had a sensitivity of 88.5% and a specificity of 88.4% avoiding 181 (59.7% biopsies, detecting 93/95 (98% of clinically significant cancers, and missing 13 (11.5% low grade, small volume tumors. Conclusions. The use of primary CPCs as a sequential test could decrease the number of initial prostate biopsies missing those cancers which are treated by active observation.

    Full Text Available This work aims the study of the photographic image in the press advisory body. It puts the press advisory body into the field of organizational communication. It seeks to answer to the following question: What strategies of senses do the photographic images build in the press advisement? In this attempt, it aims to: 1 To conceptualize photojournalism and the aspect of intentionality inherent to the production of this type of image; 2 To infer about the photographer’s intention in the photographic image produced for the purpose of press advisory body, 3 To analyze if the formats and genres of photographic image in journalism remain in the press advisory body. This work is guided by the methodological perspective ofanalytical deconstruction of photographic images in Boni (2000, as it assumes that the photographic image has its own language, with meaning and a written form that can be read, and therefore it appears as discourse. As a discourse, the photographic image in the press advisory body aims to build positive senses for the advised. The photojournalist of the press advisory body in the photographic language intends to have elements, objects and characters in order to build up concepts, values and positive representations of the advised. For analysis of the photojournalists’ intentionality, they were used 24 photographs taken from the site of the press advisory body of the Prefecture2 of Maringá-PR, referring to several articles. The first material is about the deliver of a community vegetable garden to the population of Tuiuti area.

    Full Text Available A number of public health challenges have emerged at global and national level in the last two decades. The response to these challenges has rarely been swift and often “knee-jerk.” The national and state level program officials responsible for the activities often apportion the blame on weak health systems or fragmented health service delivery mechanisms, amongst other. In India, the viral illnesses (including those due to dengue and chikungunya are becoming the increasing realities. The Public health response of early identification, disease surveillance, reporting and the preventive and curative measures, remains suboptimal. The health challenges which require multidimensional interventions are usuallyattempted to be resolved through piece meal solutions. This article proposes “policy and system approach (PSA,” combining concepts of “Health in all policies” for intersectoral coordination and “health system approach” for intra-sectoral tackling of the emerging and existing health challenges.

    Up to 25% of men with prostate cancer who undergo radical prostatectomy will recur. In this setting, salvage radiotherapy may cure patients with local recurrence, but is unable to cure those with occult metastatic disease. The objective of this study is to examine how prostate-specific antigen (PSA) response to radiotherapy predicts subsequent disease progression and survival. Using a prospectively populated database of 3089 men who underwent open radical prostatectomy, 212 patients (7%) were identified who received early salvage radiotherapy for biochemical recurrence. The main outcome was time to disease progression after salvage radiotherapy. Patients were stratified by PSA response after radiotherapy: 1) PSA radiotherapy at a median PSA of 0.20 ng/mL (IQR 0.10-0.30 ng/mL). At a median follow up of 47.3 months, a total of 52 (25%) patients experienced disease progression. On multivariable analysis, both persistent PSA (HR 5.12; 95% CI 1.98-13.23) and rising PSA (HR 16.55; 95% CI 6.61-41.48) were associated with increased risk of disease progression compared to those with PSA radiotherapy PSA, Gleason score, margin status, stage, and time to radiotherapy. Only rising PSA was associated with an increased risk of cancer-specific and all-cause mortality. PSA response is associated with the risk of disease progression following salvage radiotherapy. This information can be used to counsel patients on the potential need for additional therapy and identify those at greatest risk for progression and cancer-related mortality.

    Studies of genetic variation in the prostate-specific antigen (PSA) gene have improved the diagnostic accuracy of PSA for diagnosing prostate diseases in Caucasians. However, the reference ranges and pharmacokinetics of PSA differ significantly according to race. Therefore, we evaluated the association between genetic variations in the PSA promoter area and benign prostatic hyperplasia (BPH) phenotypes in Korean BPH patients. One hundred twenty-one men were enrolled. The initial serum PSA level, prostate size, and PSA changes at 3 months after treatment with dutasteride were determined. We amplified the promoter region of the PSA gene (nucleotide positions -158 to -356 and -5217 to -5429) and sequenced the products. Three relatively well characterized single-nucleotide polymorphisms (SNPs; rs3760722, rs266867, and rs266868), six uncharacterized SNPs (rs17554958, rs266882, rs4802754, rs2739448, rs2569733, and rs17526278), and one novel SNP (nucleotide position -5402) were found. There were no statistically significant correlations between any of the SNPs of the PSA promoter area and age-adjusted prostate sizes, initial PSA levels, or PSA variations after 3 months of dutasteride treatment. SNPs in the PSA promoter area were not associated with BPH phenotypes. We could not predict serum PSA changes after dutasteride treatment on the basis of PSA promoter genotype in Korean patients with BPH.

    Full Text Available We report a case of penile metastases from recurrent prostatic adenocarcinoma that was the first sign of a widespread metastatic disease in the absence of any increase in prostate-specific antigen (PSA level. In April 2011, an 80-year-old man presented to our Radiotherapy Unit with multiple palpable hard nodules in the penis, dysuria, and moderate perineal pain, 7 years after he had received radiotherapy for prostate cancer. Nodules in the penis had appeared in February 2011. The ultrasound and magnetic resonance (MR imaging suggested the diagnosis of multiple penile metastases. A total body computed tomography scan revealed a systemic spread of the disease, with multiple metastases in the liver, bones, and lungs. PSA level was 0.126 ng/ml. A fine needle aspiration biopsy of the liver lesion was undertaken, and the histopathologic examination revealed the prostatic origin of the metastases, so androgen deprivation therapy was started. The diagnosis of metastases should be considered in a patient with prior history of prostate malignancies presenting with solid nodules in the penis, even if the PSA level is low.

    Brookhaven National Laboratory (BNL) assisted the Korea Institute of Nuclear Safety (KINS) in reviewing the Level 2 Probabilistic Safety Assessment (PSA) of the APR+ Advanced Pressurized Water Reactor (PWR) prepared by the Korea Hydro & Nuclear Power Co., Ltd (KHNP) and KEPCO Engineering & Construction Co., Inc. (KEPCO-E&C). The work described in this report involves a review of the APR+ Level 2 PSA submittal [Ref. 1]. The PSA and, therefore, the review is limited to consideration of accidents initiated by internal events. As part of the review process, the review team also developed three sets of Requests for Additional Information (RAIs). These RAIs were provided to KHNP and KEPCO-E&C for their evaluation and response. This final detailed report documents the review findings for each technical element of the PSA and includes consideration of all of the RAIs made by the reviewers as well as the associated responses. This final report was preceded by an interim report [Ref. 2] that focused on identifying important issues regarding the PSA. In addition, a final meeting on the project was held at BNL on November 21-22, 2011, where BNL and KINS reviewers discussed their preliminary review findings with KHNP and KEPCO-E&C staffs. Additional information obtained during this final meeting was also used to inform the review findings of this final report. The review focused not only on the robustness of the APR+ design to withstand severe accidents, but also on the capability and acceptability of the Level 2 PSA in terms of level of detail and completeness. The Korean nuclear regulatory authorities will decide whether the PSA is acceptable and the BNL review team is providing its comments for KINS consideration. Section 2.0 provides the basis for the BNL review. Section 3.0 presents the review of each technical element of the PSA. Conclusions and a summary are presented in Section 4.0.

    Full Text Available OBJECTIVE: The aim of this study was to determine the incidence of asymptomatic, histologically proven prostatitis in men with symptoms of benign prostate hyperplasia and to observe the correlation between asymptomatic prostatitis and prostate specific antigen (PSA density. INTRODUCTION: The incidence of type IV prostatitis is unknown. There is a tendency to correlate the presence of inflammatory prostatitis with an elevation of PSA. MATERIALS AND METHODS: From August 2000 to January 2006, 183 patients who underwent surgical treatment for benign prostate hyperplasia as a result of obstructive or irritative symptoms were prospectively studied. In accordance with the histology findings, these patients were divided into two groups: group I included patients with the presence of histological prostatitis and group II included patients with the absence of histological prostatitis. The mean PSA densities were compared. RESULTS: Histological evidence of prostatitis was observed in 145 patients. In this group, the mean PSA density was 0.136 ± 0.095. In 38 cases, there was no evidence of inflammation upon histological examination of the surgical samples. In these 38 cases, the mean PSA density was 0.126 ± 0.129. No statistically significant differences were detected between the two groups; the p-value is 0.124. CONCLUSION: Abnormal PSA density should not be attributed to the inflammatory prostatitis process.

    Requirements on PSA for risk informed applications are expressed in different international documents. The ASME PRA standard published in spring 2002 is one such document, PSA requirements are also expressed in the European Utility Requirements (EUR) for new reactors. The Swedish PSA requirements are provided in the Swedish regulators (SKI) statutes SKIFS 2004:1. SKI also has a review handbook for PSA activities (SKI report 2003:48). The review handbook is a support during review of the utilities PSA activities and the PSAs themselves. The review handbook expresses SKIs expectations by providing so called important aspects for both the PSA work and the PSAs, A comparison of SKIFS requirements and the important aspects in the Review handbook, on one side, and the requirements on PSA in EUR and ASME on the other side, is presented. The comparison shows a large difference in the level of detail in the different documents, where ASME is most detailed and specific. This is expected since the SKI review handbook not is a 'PSA guide' in the same way as the ASME PRA standard. A direct comparison of the ASME PRA standard requirements with the important aspects in the review handbook cannot answer the question which ASME capacity level that is achieved by a PSA meeting all important aspects. The conclusion is that it is not likely to achieve capacity level 2 and 3, since very few ASME level 3 attributes are explicitly expressed as important aspects, though many are expressed in general terms. The review handbook important aspects that are most similar to the ASME capacity level 1 attributes are initiating events, sequence analysis, and system analysis while less similarity is found for analysis of operator actions data analysis, quantification and containment analysis (level 2). Less similarity is found for capacity level 2 and 3. However, the number of additional ASME attributes on capacity level 2 and 3 are few. There are also important aspects in the review

    Fucosylation is an important oligosaccharide modification associated with cancer and inflammation. We investigated whether urinary fucosylated PSA (Fuc-PSA) levels could be used for the detection of high Gleason score prostate cancer. Urine samples were collected from men with abnormal digital rectal examination findings or elevated serum PSA levels, before prostate biopsy. Lectin-antibody ELISA was used to quantify the Lewis-type or core-type fucosylated PSA (PSA-AAL) and core-type fucosylated PSA (PSA-PhoSL) in the urine samples. Both types of urinary Fuc-PSA were significantly decreased in the men with prostate cancer compared with the men whose biopsies were negative for cancer (P = 0.026 and P Gleason scores of the biopsy specimens (P = 0.001 and P Gleason score prostate cancer. The area under the receiver-operator characteristic curve (AUC) value for the prediction of cancers of Gleason score ≥ 7 was 0.69 for urinary PSA-AAL and 0.72 for urinary PSA-PhoSL. In contrast, the AUC value was 0.59 for serum PSA, 0.63 for PSA density, and 0.58 for urinary PSA. In conclusion, a decreased urinary Fuc-PSA level is a potential marker for the detection of high Gleason score prostate cancer.

    Full Text Available Abstract Background Prostate cancer is the most common tumor in men. The most commonly used diagnostic and tumor recurrence marker is Prostate Specific Antigen (PSA. After surgical removal or radiation treatment, PSA levels drop (PSA nadir and subsequent elevated or increased PSA levels are indicative of recurrent disease (PSA recurrence. For clinical follow-up and local care PSA nadir and recurrence is often hand calculated for patients, which can result in the application of heterogeneous criteria. For large datasets of prostate cancer patients used in clinical studies PSA measurements are used as surrogate measures of disease progression. In these datasets a method to measure PSA recurrence is needed for the subsequent analysis of outcomes data and as such need to be applied in a uniform and reproducible manner. This method needs to be simple and reproducible, and based on known aspects of PSA biology. Methods We have created a simple Perl-based algorithm for the calculation of post-treatment PSA outcomes results based on the initial PSA and multiple PSA values obtained after treatment. The algorithm tracks the post-surgical PSA nadir and if present, subsequent PSA recurrence. Times to PSA recurrence or recurrence free intervals are supplied in months. Results Use of the algorithm is demonstrated with a sample dataset from prostate cancer patients. The results are compared with hand-annotated PSA recurrence analysis. The strengths and limitations are discussed. Conclusions The use of this simple PSA algorithm allows for the standardized analysis of PSA recurrence in large datasets of patients who have undergone treatment for prostate cancer. The script is freely available, and easily modifiable for desired user parameters and improvements.

    Opportunistic screening of healthy men by prostate-specific antigen (PSA) testing led to a steep increase of prostate cancer incidence in Austria. The objective of this study was to quantify how many additional men are diagnosed with prostate cancer by PSA testing, to save one man from prostate cancer death. Regression models for incidence and mortality for the time periods 1983-1991 and 1992-2003 by age groups 50-59 and 60-69 years were estimated. For 1992-2003, expected numbers of incidence and mortality were calculated. The first estimates for the years 1992-2003 were calculated using the regression model including the years 1983-1991. The second estimates were also calculated using the regression model, but including only the years 1992-2003. The difference between estimates was then summed up for 1992-2003. The corresponding sums of incidence and mortality were compared to provide estimates for the effect of the introduction of PSA screening on incidence/mortality ratio. According to our calculation for the time period 1992-2003, in age group 50-69 years, a total of 512 expected prostate cancer deaths were prevented because of opportunistic PSA screening, whereas PSA testing identified a total of 9648 additional men with asymptomatic prostate cancer. In conclusion, to save one man in the age group 50-69 years in the time period 1992-2003 from prostate cancer death by PSA testing, a total of 18.8 men with asymptomatic prostate cancer had to be identified. Although this study probably underestimates the benefit (reduced mortality) and overestimates excess incidence of prostate cancer, it is far from sure that in all of these additionally identified men prostate cancer would ever have surfaced as a clinical disease, if not screened for.

    This document, the Probabilistic Safety Assessment(PSA) procedures guide for system analysis, is intended to provide the guidelines to analyze the target of system consistently and technically in the performance of PSA for nuclear power plants(NPPs). The guide has been prepared in accordance with the procedures and techniques for fault tree analysis(FTA) used in system analysis. Normally the main objective of system analysis is to assess the reliability of system modeled by Event Tree Analysis(ETA). A variety of analytical techniques can be used for the system analysis, however, FTA method is used in this procedures guide. FTA is the method used for representing the failure logic of plant systems deductively using AND, OR or NOT gates. The fault tree should reflect all possible failure modes that may contribute to the system unavailability. This should include contributions due to the mechanical failures of the components, Common Cause Failures (CCFs), human errors and outages for testing and maintenance. After the construction of fault tree is completed, system unavailability is calculated with the CUT module of KIRAP, and the qualitative and quantitative analysis is performed through the process as above stated. As above mentioned, the procedures for system analysis is based on PSA procedures and methods which has been applied to the safety assessments of constructing NPPs in the country. Accordingly, the method of FTA stated in this procedures guide will be applicable to PSA for the NPPs to be constructed in the future. (author). 6 tabs., 11 figs., 7 refs.

    2017-07-01

    Full Text Available Prostate-specific antigen (PSA testing of men at normal risk of prostate cancer is one of the most contested issues in cancer screening. There is no formal screening program, but testing is common – arguably a practice that ran ahead of the evidence. Public and professional communication about PSA screening has been highly varied and potentially confusing for practitioners and patients alike. There has been much research and policy activity relating to PSA testing in recent years. Landmark randomised controlled trials have been reported; authorities – including the 2013 Prostate Cancer World Congress, the Prostate Cancer Foundation of Australia, Cancer Council Australia, and the National Health and Medical Research Council – have made or endorsed public statements and/or issued clinical practice guidelines; and the US Preventive Services Task Force is revising its recommendations. But disagreement continues. The contention is partly over what the new evidence means. It is also a result of different valuing and prioritisation of outcomes that are hard to compare: prostate cancer deaths prevented (a small and disputed number; prevention of metastatic disease (somewhat more common; and side-effects of treatment such as incontinence, impotence and bowel trouble (more common again. A sizeable proportion of men diagnosed through PSA testing (somewhere between 20% and 50% would never have had prostate cancer symptoms sufficient to prompt investigation; many of these men are older, with competing comorbidities. It is a complex picture. Below are four viewpoints from expert participants in the evolving debate, commissioned for this cancer screening themed issue of Public Health Research & Practice. We asked the authors to respond to the challenge of PSA testing of asymptomatic, normal-risk men. They raise important considerations: uncertainty, harms, the trustworthiness and interpretation of the evidence, cost (e.g. of using multiparametric

    Prostate cancer is one of the most common cancers in men. Traditional screening and diagnostic methods include digital rectal examinations (DREs), biopsies and serum prostate-specific antigen (PSA) tests, with the latter being the more popular. PSA is a biomarker for prostate cancer; however, it is highly sensitive to external factors as well as other prostate diseases. As such, the reliability of of the serum PSA level as a sole screening and diagnostic tool for prostate cancer is controversial. Recently, it has been shown that fasting extremes can affect concentrations of serum chemistry analytes, thus raising the question of whether or not fasting has an effect on the highly sensitive PSA biomarker. Patients testing for serum PSA levels are often concomitantly submitting to other tests that require fasting, subjecting certain patients to a fasting PSA level while others not. The objective of this study was to investigate whether this discrepancy in fasting state translates into an effect on serum PSA levels. Serum PSA levels and fasting time records for 157 276 men who underwent testing at Calgary Laboratory Services (CLS; Calgary, Alberta, Canada) between 01 January 2010 and 31 March 2013 were accessed. Linear regression models of mean PSA levels and fasting times revealed a statistically important relationship at certain fasting times. Applying a dynamic mathematical model to explore the clinical effect of fasting suggests minimal impact on serum PSA result interpretation. Thus, patients can be tested for serum PSA levels regardless of their fasting state. PMID:24994780

    Full Text Available Aim. To evaluate the toxicity of a hypofractionated schedule for primary radiotherapy (RT of prostate cancer as well as the value of the nadir PSA (nPSA and time to nadir PSA (tnPSA as surrogate efficacy of treatment. Material and Methods. Eighty patients underwent hypofractionated schedule by Helical Tomotherapy (HT. A dose of 70.2 Gy was administered in 27 daily fractions of 2.6 Gy. Acute and late toxicities were graded on the RTOG/EORTC scales. The nPSA and the tnPSA for patients treated with exclusive RT were compared to an equal cohort of 20 patients treated with conventional fractionation and standard conformal radiotherapy. Results. Most of patients (83% did not develop acute gastrointestinal (GI toxicity and 50% did not present genitourinary (GU toxicity. After a median follow-up of 36 months only grade 1 of GU and GI was reported in 6 and 3 patients as late toxicity. Average tnPSA was 30 months. The median value of nPSA after exclusive RT with HT was 0.28 ng/mL and was significantly lower than the median nPSA (0.67 ng/mL of the conventionally treated cohort (P=0.02. Conclusions. Hypofractionated RT schedule with HT for prostate cancer treatment reports very low toxicity and reaches a low level of nPSA that might correlate with good outcomes.

    The aim of the study was to evaluate the relationship between serum free and total PSA and histopathological findings in women with fibrocystic mastopathy. 176 women with fibrocystic breast disease, aged 18 to 45 years.--Group I: comprised 114 patients with cysts 10 mm in diameter. The control group consisted of 46 healthy women aged 18 - 45 years who had no breast pathology Total PSA (PSA-T) and free PSA (PSA-Free) were measured by an ultra-sensitive fluoroimmunometric DELFIA assay (Prostatus PSA Free/Total Wallac, Turku, Finland). The detection limit for PSA was 0.01 ng/ml. Endometrial samples have been obtained with Pipelle probe between 22 and 24 days of the menstrual cycle. In the control group secretory endometrium was more frequently detected than in the mastopathy group (chi2 = 11,15, p = 0.01). Proliferatory (chi2 = 8.27, p = 0.004) and presecretory endometrium (chi2 = 4.61, p = 0.03) were more frequently detected in the mastopathy group than in controls. We did not find statistically significant relationship between the mean PSA concentrations between the groups in relation to histopathological findings. No relationships between free and total PSA measured in the follicular phase of the menstrual cycle and endometrial findings were detected in our study. Further research is required to evaluate the relationship between PSA and endometrial findings.

    To investigate the potential relationship of steroid usage with prostate-specific antigen (PSA) flare as well as the prognostic impact of PSA flare, which is known to occur in 10-20% of patients with metastatic castration-resistant prostate cancer during docetaxel chemotherapy. This study included 71 patients with metastatic castration-resistant prostate cancer treated by docetaxel chemotherapy with co-introduction of a steroid. PSA flare was defined as a transient PSA increase followed by a PSA decrease. PSA flare was recognized in 7.0-23.9% of patients according to the definition used. Intriguingly, men with steroid intake before the initiation of docetaxel chemotherapy experienced significantly fewer PSA flares. The progression-free survival rate in men with PSA flare was equivalent to that of PSA responders, but significantly better than men with PSA failure. Our results suggest that de novo steroid co-introduction with docetaxel chemotherapy induces the PSA flare phenomenon. This novel finding may account for the mechanism of PSA flare as well as being valuable for distinguishing PSA elevation attributable to PSA flare from that attributable to PSA failure. © 2016 The Authors BJU International © 2016 BJU International Published by John Wiley & Sons Ltd.

    BACKGROUND: The prognostic value of prostate-specific antigen (PSA) kinetics in untreated prostate cancer (PCa) patients is debatable. We investigated the association between PSA doubling time (PSAdt), PSA velocity (PSAvel) and PSAvel risk count (PSAvRC) and PCa mortality in a cohort of patients...... were included of which 116, 76 and 71 had a PSA at consent ≤10, 10.1-25, and >25 ng/ml, respectively.

    The role of pneumococcal (Pnc) surface adhesin A (PsaA) in the adherence of Streptococcus pneumoniae (pneumococcus) to host cells is not well defined. We examined the effect of anti-PsaA antibodies in an inhibition of adherence assay using Detroit 562 nasopharyngeal human epithelial cells. Rabbit polyclonal (Pab) anti-recombinant PsaA (rPsaA) sera, a purified mouse monoclonal antibody (MAb) (MAb 6F62G8E12), and 22 healthy adult sera with known anti-PsaA IgG levels (obtained by enzyme-linked immunosorbent assay) were evaluated for their abilities to inhibit Pnc adherence to confluent monolayers (measured as percent reduction in CFU counts compared to those of uninhibited controls). Pnc adherence was dependent on capsular phenotype (no or low adherence for opaque strains). With an inoculum of 10(4) to 10(5) bacteria/well, the mean +/- standard deviation count in controls was 163 +/- 32 CFU/well for transparent strains. Low adherence was observed for a PsaA-minus mutant even at higher inoculum doses. Mean percent inhibitions of adherence with Pab and MAb were 54 and 50%, respectively. Adult sera showed inhibition in a dose-response fashion with a range of 98 to 8%, depending on the serum anti-PsaA antibody concentration. Absorption of Pab with rPsaA restored Pnc adherence to control levels. Absorption of sera with a PsaA-minus mutant did not result in a significant decrease (P >0.05) of inhibition of adherence activity. Additionally, nearly 100% of Pnc adherence was inhibited by lipidated rPsaA at 2.5 micro g/ml. Our data support the argument that PsaA is an adhesin that mediates Pnc adherence to human nasopharyngeal cells. This functional assay may be useful in evaluating antibodies elicited in response to PsaA vaccination.

    On the basis of 150 patients (16 controls with no disease of the prostate, 96 cases of benign prostatic hypertrophy (BPH) and 38 cases of carcinoma of the prostate (CP)), the authors intended to answer 3 questions: How can the borderline values of PSA in BPH be interpreted? Is there a correlation between the Gleason and PSA values in carcinomas? Should the simultaneous measurements of PSA and PAP be continued? All patients were examined with a rectal touch, transrectal echography (TRE) and PAS and PAP assays. All CP were examined with bone radionuclide scanning (BR). The correlation coefficient being 0.391 (p 0.001), the PSA value and prostatic weight can be regarded as linearly correlated in BPH (5 g BPH = 1 ng/ml PSA). This lower value of PSA is linked with the increase produced by TRE in the assessment of prostatic weight. On the other hand, the authors did no observe a correlation between the PSA and the Glisson grade in carcinomas with negative BR. Lastly, the sensitivity of PSA is noticeably higher than that of PAP (75% vs. 50%), and no false negative finding with PSA was corrected by PAP measurements.

    In this study, the changing process of an internal event PSA model to a fire event PSA model is analytically presented and discussed. Many fire PSA models have fire induced initiating event fault trees not shown in an internal event PSA model. Fire-induced initiating fault tree models are developed for addressing multiple initiating event issues. A single fire event within a fire compartment or fire scenario can cause multiple initiating events. As an example, a fire in a turbine building area can cause a loss of the main feed-water and loss of off-site power initiating events. Up to now, there has been no analytic study on the construction of a fire event PSA model using an internal event PSA model with fault trees of initiating events. In this paper, the changing process of an internal event PSA model to a fire event PSA model was analytically presented and discussed. This study results show that additional cutsets can be obtained if the fault trees of initiating events for a fire event PSA model are not exactly developed.

    US NRC/EPRI issued a new fire PSA method represented by NUREG/CR 6850, and have been training many operators and inspectors to widely spread the new method. However, there is a limitation in time and efficiency for many foreigners, who generally have communication problem, to participate in the EPRI/NRC training to learn the new method. Since it is about time to introduce the new fire PSA method as a regulatory requirement for the fire protection in Korea, a simple and easy-understandable base model for the fire PSA training is required, and KAERI-KINS is jointly preparing the base model for the new fire PSA training. This paper describes how the base model is developed. Using an imaginary simple NPP, a base model of fire PSA following the new fire PSA method was developed in two ways from the internal PSA model. Since we have the base model and know the process of making the fire PSA model, the training for the new fire PSA method can be in detail performed in Korea.

    2014-01-01

    Full Text Available Introduction: Prostate-specific antigen (PSA bounce after brachytherapy has been well-documented. This phenomenon has also been identified in patients undergoing stereotactic body radiation therapy (SBRT. While the parameters that predict PSA bounce have been extensively studied in prostate brachytherapy patients, this study is the first to analyze the clinical and pathologic predictors of PSA bounce in prostate SBRT patients. Materials and Methods: Our institution has maintained a prospective database of patients undergoing SBRT for prostate cancer since 2006. Our study population includes patients between May 2006 and November 2011 who have at least 18 months of follow-up. All patients were treated using the CyberKnife treatment system. The prescription dose was 3500-3625cGy in 5 fractions.Results: 120 patients were included in our study. Median PSA follow-up was 24 months (range 18-78 months. 34 (28% patients had a PSA bounce. The median time to PSA bounce was 9 months, and the median bounce size was 0.50ng/mL. On univariate analysis, only younger age (p = .011 was shown to be associated with an increased incidence of PSA bounce. Other patient factors, including race, prostate size, prior treatment by hormones, and family history of prostate cancer, did not predict PSA bounces. None of the tumor characteristics studied, including Gleason score, pre-treatment PSA, T-stage, or risk classification by NCCN guidelines, was associated with increased incidence of PSA bounces. Younger age was the only statistically significant predictor of PSA bounce on multivariate analysis (OR = 0.937, p = 0.009.Conclusion: PSA bounce, which has been reported after prostate brachytherapy, is also seen in a significant percentage of patients after CyberKnife SBRT. Close observation rather than biopsy can be considered for these patients. Younger age was the only factor that predicted PSA bounce.

At OMERACT 2016, research conducted to update the PsA Core Domain Set was presented and discussed in breakout groups. The updated PsA Core Domain Set was voted on and endorsed by OMERACT participants. We conducted a systematic literature review of domains measured in PsA RCT and LOS, and identified 24 domains. We conducted 24 focus groups with 130 patients from 7 countries representing 5 continents to identify patient domains. We achieved consensus through 2 rounds of separate surveys with 50 patients and 75 physicians, and a nominal group technique meeting with 12 patients and 12 physicians. We conducted a workshop and breakout groups at OMERACT 2016 in which findings were presented and discussed. The updated PsA Core Domain Set endorsed with 90% agreement by OMERACT 2016 participants included musculoskeletal disease activity, skin disease activity, fatigue, pain, patient's global assessment, physical function, health-related quality of life, and systemic inflammation, which were recommended for all RCT and LOS. These were important, but not required in all RCT and LOS: economic cost, emotional well-being, participation, and structural damage. Independence, sleep, stiffness, and treatment burden were on the research agenda. The updated PsA Core Domain Set was endorsed at OMERACT 2016. Next steps for the PsA working group include evaluation of PsA outcome measures and development of a PsA Core Outcome Measurement Set.

    The purpose of this study was to investigate the effect of total prostate-specific antigen (PSA) at the time of (11)C-choline PET/CT (trigger PSA), PSA velocity (PSAvel), and PSA doubling time (PSAdt) on (11)C-choline PET/CT detection rate in patients treated with radical prostatectomy for prostate cancer, who showed biochemical failure during follow-up. A total of 190 patients treated with radical prostatectomy for prostate cancer who showed an increase in PSA (mean, 4.2; median, 2.1; range, 0.2-25.4 ng/mL) were retrospectively enrolled. All patients were studied with (11)C-choline PET/CT. Patients were grouped according to trigger PSA (PSA 5 ng/mL). In 106 patients, data were available for calculation of PSAvel and PSAdt. Logistic regression analysis was used to determine whether there was a relationship between PSA levels and PSA kinetics and the rate of detection of relapse using PET. (11)C-choline PET/CT detected disease relapse in 74 of 190 patients (38.9%). The detection rate of (11)C-choline PET/CT was 19%, 25%, 41%, and 67% in the 4 subgroups-PSA 5 ng/mL (49 patients)-respectively. Trigger PSA values were statistically different between PET-positive patients (median PSA, 4.0 ng/mL) and PET-negative patients (median PSA, 1.4 ng/mL) (P = 0.0001). Receiver-operating-characteristic analysis showed an optimal cutoff point for trigger PSA of 2.43 ng/mL (area under the curve, 0.76). In 106 patients, PSAdt and PSAvel values were statistically different between patients with PET-positive and -negative scan findings (P = 0.04 and P = 0.03). The (11)C-choline PET/CT detection rate was 12%, 34%, 42%, and 70%, respectively, in patients with PSAvel 5 ng/mL/y (28 patients). The (11)C-choline PET/CT detection rate was 20%, 40%, 48%, and 60%, respectively, in patients with PSAdt > 6 mo (45 patients), 4 < PSAdt

    Since prostate cancer reaches the advanced and non curable stage in the absence of any specific symptom or sign, it seems reasonable to diagnose this cancer at an early and curable stage. Screening by prostate-specific antigen (PSA) has been the common technology used. The last follow-up of the first two prospective and randomized screening studies for prostate cancer, namely the Quebec and ERSPC (European Randomized Study of Screening for Prostate Cancer) clinical trials started in 1988 and 1991, respectively, have shown reductions of prostate cancer death of 62% (PProstate Lung Colorectal and Ovarian Cancer) screening trial reported no benefit. It has been estimated, however, that 85% of men in the planned 'non-screened' group of the US study have been screened. With such a serious flaw, the PLCO study does not have the statistical power to reach any valid conclusion. In the Quebec study, only 7.3% of men were screened in the control arm. The important benefit observed in the ERSPC study was achieved using a less than optimal 4-year PSA screening interval which misses a significant number of cancers while the Quebec study used the optimal 1-year interval. With proper information obtained from their physicians or otherwise using data collected only from the clinical trials having the required statistical power, men should be in a good position to decide about being or not being screened for prostate cancer.

    Full Text Available OBJECTIVE: Cancer detection has been reported in up to 27% of patients when lowering the PSA cutoff to 2.5 ng/mL. Although this practice could increase the number of biopsies performed, it also could lead to more frequent detection of significant prostate cancers at an organ-confined stage and/or a less aggressive state. This study describes the incidence of malignancy and tumor characteristics in extended prostate biopsies with PSA ≤ 4 ng/mL. MATERIALS AND METHODS: Prostate biopsies from 1081 patients where examined, 275 (25.4% patients had PSA level ≤ 4 ng/mL. RESULTS: Cancer was diagnosed in 32.0% and 35.7% of patients with PSA ≤ 4 ng/mL and > 4 ng/mL, respectively (p = 0.906. The median Gleason score was 7 independent of PSA > or ≤ 4 ng/mL (p = 0.078. The median number of cores positive for tumor was 4 and 3, respectively, for PSA > 4 ng/mL and PSA ≤ 4 ng/mL (p = 0.627. There was a difference in the total percent of tumors involving all cores, 11% and 7% for PSA > or ≤ 4 ng/mL (p = 0.042. Fifty-six patients underwent radical prostatectomy, 12 had PSA ≤ 4 ng/mL. In both groups, a diagnosis of cancer was accurate with no differences in Gleason score, tumor volume or staging for both groups. CONCLUSION: When PSA is below 4 ng/mL, cancer is detected in a proportion equal to the proportion diagnosed with a PSA > 4 ng/mL, and tumor characteristics are similar between the two groups. Only clinically significant tumors were diagnosed following radical prostatectomy.

    Permanent low-dose-rate brachytherapy (BT) with iodine 125 is an established curative treatment for localized prostate cancer. After treatment, prostate-specific antigen (PSA) kinetics may show a transient rise (PSA bounce). Our aim was to investigate the association of PSA bounce with biochemical control. Patients treated with BT in Switzerland were registered in a prospective database. Only patients with a follow-up of at least 2 years were included in our analysis. Clinical follow-up and PSA measurements were assessed after 1.5, 3, 6, and 12 months, and annually thereafter. If PSA increased, additional follow-up visits were scheduled. Cases of PSA bounce were defined as a rise of at least 0.2 ng/ml above the initial PSA nadir with a subsequent decline to or below the initial nadir without treatment. Biochemical failure was defined as a rise to nadir + 2 ng/ml. Between March 2001 and November 2010, 713 patients with prostate cancer undergoing BT with at least 2 years of follow-up were registered. Median follow-up time was 41 months. Biochemical failure occurred in 28 patients (3.9 %). PSA bounce occurred in 173 (24.3 %) patients; only three (1.7 %) patients with PSA bounce developed biochemical failure, in contrast to 25 (4.6 %) patients without previous bounce (p < 0.05). The median time to bounce was 12 months, the median time to biochemical failure was 30 months. The median bounce increase was 0.78 ng/ml. Twenty-eight patients with bounce (16.5 %) had a transient PSA rise of + 2 ng/ml above the nadir. In most cases, an early increase in PSA after BT indicates PSA bounce and is associated with a lower risk of biochemical failure. (orig.)

    To study 18F-Choline PET/CT in the diagnosis and biopsy guide of prostate cancer (pCa) in patients with persistently high prostate-specific antigen (PSA) and previous negative prostate biopsy. To compare the clinical risk factors and metabolic variables as predictors of malignancy. Patients with persistently elevated PSA in serum (total PSA >4ng/mL) and at least a previous negative or inconclusive biopsy were consecutively referred for a whole body 18F-Choline PET/CT. Patient age, PSA level, PSA doubling time (PSAdt) and PSA velocity (PSAvel) were obtained. PET images were visually (positive or negative) and semiquantitatively (SUVmax) reviewed. 18F-Choline uptake prostate patterns were defined as focal, multifocal, homogeneous or heterogeneous. Histology on biopsy using transrectal ultrasound-guided approach was the gold standard. Sensitivity (Se), specificity (Sp) and accuracy (Ac) of PET/CT for diagnosis of pCa were evaluated using per-patient and per-prostate lobe analysis. Receiver-operating-characteristic (ROC) curve analysis was used to assess the value of SUVmax to diagnose pCa. Correlation between PET/CT and biopsy results per-prostate lobe was assessed using the Chi-square test. Univariate and multivariate logistic regression analysis were applied to compare clinical risk factors and metabolic variables as predictors of malignancy. Thirty-six out of 43 patients with histologic confirmation were included. In 11 (30.5%) patients, pCa was diagnosed (Gleason score from 4 to 9). The mean values of patient age, PSA level, PSAdt and PSAvel were: 65.5 years, 15.6ng/ml, 28.1 months and 8.5ng/mL per year, respectively. Thirty-three patients had a positive PET/CT; 18 had a focal pattern, 7 multifocal, 4 homogeneous and 4 heterogeneous. Se, Sp and Ac of PET/CT were of 100%, 12% and 38% in the patient based analysis, and 87%, 29% and 14% in the prostate lobe based analysis, respectively. The ROC curve analysis of SUVmax showed an AUC of 0.568 (p=0.52). On a lobe

    Prostate-specific antigen (PSA) is a glycoprotein secreted by prostate epithelial cells. PSA is currently used as a marker of prostate carcinoma because high levels of PSA are indicative of a tumor situation. However, PSA tests still suffer from a lack of specificity to distinguish between benign prostate hyperplasia and prostate cancer. To determine whether PSA glycosylation could provide a means of differentiating between PSA from normal and tumor origins, N-glycan characterization of PSA from seminal fluid and prostate cancer cells (LNCaP cell line) by sequencing analysis and mass spectrometry was carried out. Glycans from normal PSA (that correspond to low and high pI PSA fractions) were sialylated biantennary complex structures, half of them being disialylated in the low pI PSA fraction and mostly monosialylated in the high pI PSA. PSA from LNCaP cells was purified to homogeneity, and its glycan analysis showed a significantly different pattern, especially in the outer ends of the biantennary complex structures. In contrast to normal PSA glycans, which were sialylated, LNCaP PSA oligosaccharides were all neutral and contained a higher fucose content. In 10-15% of the structures fucose was linked alpha1-2 to galactose, forming the H2 epitope absent in normal PSA. GalNAc was increased in LNCaP glycans to 65%, whereas in normal PSA it was only present in 25% of the structures. These carbohydrate differences allow a distinction to be made between PSA from normal and tumor origins and suggest a valuable biochemical tool for diagnosis and follow-up purposes.

    To explore the distribution characteristics of leukocytes in expressed prostatic secretions (EPS) in a large Chinese male population and the correlation with leukocytes and prostate-specific antigen (PSA) levels. From September to December 2009, EPS specimens were collected from 2504 men (age 20-69 years) who had undergone prostatic massage and were recruited from a large-scale community-based population survey in Southern China. The EPS specimens were divided into 5 categories according to the leukocyte count. The lifestyle and demographic characteristics were obtained by questionnaire. Asymptomatic and symptomatic men were defined according to the findings from the National Institutes of Health-Chronic Prostatitis Symptom Index questionnaire. EPS specimens were successfully collected from 1779 of the 2504 participants (71%). The degree of inflammation in the EPS specimens progressively increased with age, education, and body mass index (P EPS progressively increases with increasing age, body mass index, and education. Moreover, an increase of leukocytes in the EPS specimen correlated with increasing PSA levels. Prospective studies are needed to determine whether the minor elevations have clinical significance for prostatitis assessment. Copyright © 2013 Elsevier Inc. All rights reserved.

  10. Self-assembled particulate PsaA as vaccine against Streptococcus pneumoniae infection

    2017-04-01

    Full Text Available Streptococcus pneumoniae is a human pathogen responsible for the majority of childhood pneumonia and media otitis cases worldwide. The diversity of its capsular polysaccharides (CPS results in more than 91 serotypes of which at least 23 are virulent. Various CPS conjugated to immunogenic carrier proteins are currently licensed and provide protection against the infection caused by the respective serotypes but not against new and emerging virulent serotypes. In this study, we considered the conserved protein antigen PsaA, the pneumococcal surface adhesin A, in order to overcome the limitations of CPS antigens. The PsaA was translationally fused to a polyhydroxybutyrate (PHB synthase which mediated production of PsaA displayed on PHB inclusions in recombinant Escherichia coli. This suggested that the PsaA fusion to the PHB synthase did not interfere with PHB synthase activity and its ability to mediate formation of nano-sized inclusions composed of a PHB core surrounded by the PHB synthase fused to PsaA. Isolated PHB beads showed a negative surface charge. Transmission electron microscopy analysis suggested that the PsaA fusion to the PHB synthase reduced the size of PHB beads from about 500 nm to 100 nm. The integrity and antigenicity of the fusion protein attached to isolated PHB beads was confirmed by SDS-PAGE, tryptic peptide fingerprinting analysis using MALDI-TOF-MS/MS and immunoblotting using a monoclonal anti-PsaA antibody. Mice immunized with PsaA displaying PHB beads produced high and specific IgG levels dominated by IgG1 isotype. While IgG1 titer were similar between soluble and insoluble PsaA, the IgG2 titers were strongly increased upon vaccination with insoluble PsaA i.e. PsaA displayed on PHB beads. Particulate PsaA-PHB beads elicited IgG antibodies recognizing PsaA in whole cell lysates of seven different serotypes of S. pneumoniae. This study suggested that PHB beads are suitable carriers for PsaA in order to induce a significant

    We demonstrated multi-span transmission using a periodically poled LiNbO(3) (PPLN) based phase sensitive amplifier (PSA). An in-line PSA with a carrier recovery and phase locking system is implemented as a repeater amplifier in a recirculating loop. We achieved a PSA gain as high as + 18 dB and a high external gain of + 12 dB for the in-line PSA as a black box. The impairments caused by phase noise resulting from fiber nonlinearity and intensity noise caused by the amplified spontaneous emission (ASE) of an optical amplifier are largely suppressed using the phase and amplitude regeneration capabilities of the PSA. The ultra long-haul transmission of a 28-Gb/s binary phase shift keying (BPSK) signal over 5400 km was achieved with phase and amplitude regeneration.

    Customer requirements to probabilistic safety targets are usually stronger than existing Regulatory or IAEA ones. It appears that industry takes the lead over regulation in this case and forces the designer to find and implement appropriate means to enhance safety, which sometimes have no reference to practical experience. On the other hand, regulatory documents and the existing PSA methodology are mainly oriented to operating plants. This creates problems when developing a PSA as well as performing regulatory reviews. The scope of the PSA may be different depending on a design stage such as the development conceptual, basic or detailed design. In addition, the base case PSA is usually performed for NPP in design. However, a customer may require additional PSA applications to consider, for instance, risk monitoring. In this case the scope of the PSA should be extended to implement special attributes of the application needed that often requires specific information not available at the design stage. Lack of design information affecting PSA development may be associated with incompleteness of the design that is typical for interim design stages and communication problems caused by the involvement of many different companies in the deign activity. To deal with this issue bounding technologies and the iterative PSA development are used. However this sometimes contradicts to the ''best estimate'' approach recommended by regulatory guides. PSA development for advanced NPPs has raised some issues originated from unknown new components, processes and technologies incorporated into the design of an advanced plant. The paper addresses some issues resolved while carrying out PSAs for advanced NPPs. Some PSA results for new advanced VVER plants under construction and the first lessons learnt from the Fukushima accident are also discussed. (orig.)

    E9802 was a phase 2 multi-institution study conducted to evaluate the safety and effectiveness of vaccinia and fowlpox prostate-specific antigen (PSA) vaccine (step 1) followed by combination with androgen ablation therapy (step 2) in patients with PSA progression without visible metastasis. To test the hypothesis that vaccine therapy in this early disease setting will be safe and have a biochemical effect that would support future studies of immunotherapy in patients with minimal disease burden. Patients who had PSA progression following local therapy were treated with PROSTVAC-V (vaccinia)/TRICOM on cycle 1 followed by PROSTVAC-F (fowlpox)/TRICOM for subsequent cycles in combination with granulocyte-macrophage colony-stimulating factor (step 1). Androgen ablation was added on progression (step 2). Step 1 primary end points included progression at 6 mo and characterization of change in PSA velocity pretreatment to post-treatment. Step 2 end points included PSA response with combined vaccine and androgen ablation. In step 1, 25 of 40 eligible patients (63%) were progression free at 6 mo after registration (90% confidence interval [CI], 48-75). The median pretreatment PSA velocity was 0.13 log(PSA)/mo, in contrast to median postregistration velocity of 0.09 log(PSA)/mo (p=0.02), which is an increase in median PSA doubling time from 5.3 mo to 7.7 mo. No grade ≥4 treatment-related toxicity was observed. In the 27 patients eligible and treated for step 2, 20 patients achieved a complete response (CR) at 7 mo (CR rate: 74%; 90% CI, 57-87). Although supportive of larger studies in the cooperative group setting, this study is limited by the small number of patients and the absence of a control group as in a phase 3 study. A viral PSA vaccine can be administered safely in the multi-institutional cooperative group setting to patients with minimal disease volume alone and combined with androgen ablation, supporting the feasibility of future phase 3 studies in this

Objects of research. Objects of research consisted of 110 patients treated in urological clinic of Hospital n.a. S. R. Mirotvortsev (Saratov State Medical University during the period February, 2009 — March, 2012. Patients took 110 sessions of primary operative treatment of prostate cancer by HIFU therapy method. Technique and research methods. Concentration of PSA in blood changed in all patients every 1,5 month within 6 months after operation, irrespective of its kind (including after repeated HIFU, further — after every 3 month till one year, and later on after 6 months. We were guided by references of the International Consensus, which considers PSA level more than 0,5 ng/ml in blood after 3 months of treatment to be unsatisfactory result. We also headed for PSA level before treatment and oncological risk degree. Results. Median nadir formed 0,5 ng/ml PSA by 3 months after treatment. Patients demonstrated different indicators of PSA dynamics depending on oncological risk, stage and hormonal therapy management. Patients with low oncological risk had initially lower PSA concentration, further PSA concentration reached nadir level faster. At patients with widespread forms of prostate cancer accurate dependence of PSA concentration according to prevalence of process was traced. Time of PSA nadir amount did not differ and was marked as 12-14 weeks on average. At patients received hormonal therapy, lower value of PSA nadir was marked. The conclusion. Monitoring of PSA concentration (PSA nadir by 3 months, dynamics of PSA concentration change is of great importance in early revealing of relapse after prostate HIFU therapy. High level of PSA nadir and PSA growth according to time period are important prognostic factors.

    The conventional PSA techniques cannot adequately evaluate all events. The conventional PSA models usually focus on single internal events such as DBAs, the external hazards such as fire, seismic. However, the Fukushima accident of Japan in 2011 reveals that very rare event is necessary to be considered in the PSA model to prevent the radioactive release to environment caused by poor treatment based on lack of the information, and to improve the emergency operation procedure. Especially, the results from PSA can be used to decision making for regulators. Moreover, designers can consider the weakness of plant safety based on the quantified results and understand accident sequence based on human actions and system availability. This study is for PSA modeling of combined accidents including total loss of feedwater (TLOFW) accident. The TLOFW accident is a representative accident involving the failure of cooling through secondary side. If the amount of heat transfer is not enough due to the failure of secondary side, the heat will be accumulated to the primary side by continuous core decay heat. Transients with loss of feedwater include total loss of feedwater accident, loss of condenser vacuum accident, and closure of all MSIVs. When residual heat removal by the secondary side is terminated, the safety injection into the RCS with direct primary depressurization would provide alternative heat removal. This operation is called feed and bleed (F and B) operation. Combined accidents including TLOFW accident are very rare event and partially considered in conventional PSA model. Since the necessity of F and B operation is related to plant conditions, the PSA modeling for combined accidents including TLOFW accident is necessary to identify the design and operational vulnerabilities.The PSA is significant to assess the risk of NPPs, and to identify the design and operational vulnerabilities. Even though the combined accident is very rare event, the consequence of combined

    To examine accuracy of patient-reported prostate-specific antigen (PSA) levels among indigent, uninsured men in a state-funded prostate cancer treatment program that provides case management, care coordination, and health education. Program evaluation. About 114 men with matched self- and lab-reported PSA levels at program enrollment and another time point within 18 months. Abstraction of self- and lab-reported PSA levels to determine self-report as "accurate" or "inaccurate," and evaluate accuracy change over time, before and after nursing interventions. Chi-square tests compared patients with accurate versus inaccurate PSA values. Nonlinear multivariate analyses explored trends in self-reported accuracy over time. Program enrollees receive prostate cancer education from a Nurse Case Manager (NCM), including significance of PSA levels. Men self-report PSA results to their NCM following lab draws and appointments. The NCM provides ongoing education about PSA levels. Of the sample, 46% (n = 53) accurately reported PSA levels. Accuracy of PSA self-reports improved with increasing time since program enrollment. Compared with men at public facilities, those treated at private facilities showed increasing accuracy in self-reported PSA (p = .038). A targeted nursing intervention may increase specific knowledge of PSA levels. Additionally, the provider/treatment setting significantly impacts a patient's disease education and knowledge. © 2016 Wiley Periodicals, Inc.

    A potentiometric stripping analysis (PSA) method has been developed and checked for the fast and reliable determination of antimony in vegetation samples of Cistus ladanifer from a mining area in Badajoz, Southwest Spain. The method, modified from previous PSA methods for Sb in environmental samples, is based on dry ashing of the homogenized leaves, dissolution in hydrochloric acid, and PSA analysis on a mercury film plated on to a glassy carbon disk electrode. The influence of experimental variables such as the deposition potential, the deposition time, the signal stability and the calibration parameters, has been investigated. The method has been compared with an independent technique (instrumental neutron activation analysis) by analysis of standards and reference materials and comparison of the results. As a result of automation of the PSA equipment, the proposed method enables unattended analysis of 20 digested samples in a total time of 2 h, thus providing a useful tool for Sb monitoring of a large number of samples.

    Bryce, A H; Alumkal, J J; Armstrong, A

    2017-01-01

    BACKGROUND: Advanced prostate cancer is a phenotypically diverse disease that evolves through multiple clinical courses. PSA level is the most widely used parameter for disease monitoring, but it has well-recognized limitations. Unlike in clinical trials, in practice, clinicians may rely on PSA...... monitoring alone to determine disease status on therapy. This approach has not been adequately tested. METHODS: Chemotherapy-naive asymptomatic or mildly symptomatic men (n=872) with metastatic castration-resistant prostate cancer (mCRPC) who were treated with the androgen receptor inhibitor enzalutamide...... treated with enzalutamide. As restaging in advanced prostate cancer patients is often guided by increases in PSA levels, our results demonstrate that disease progression on enzalutamide can occur without rising PSA levels. Therefore, a disease monitoring strategy that includes imaging not entirely reliant...

    Safety inspections of nuclear power plants under the Atomic Energy Act are regulated, inter alia, in the Probabilistic Safety Analysis (PSA) guideline. These analyses are performed in addition to the safety assessments based, on deterministic principles. In this way, the influence of components, systems, and structures, as well as actions by personnel, on plant behavior in terms of technical safety can be described in a holistic approach and the safety level thus can be assessed quantitatively. Conducting a PSA requires plant-specific reliability data which are determined in the plant in question, but are also collected and stored centrally in the central reliability and event database (ZEDB).

    We evaluated the potential of (18)F-fluoromethyldimethyl-2-hydroxyethyl-ammonium (FCH) PET/CT in the detection of recurrent disease or distant metastases and correlated its diagnostic accuracy with prostate-specific antigen (PSA) levels in prostate cancer patients with biochemical evidence of recurrence. Furthermore, the influences of androgen deprivation therapy (ADT) and its duration on (18)F-FCH PET were assessed in this study. This prospective study included 250 prostate cancer patients with PSA relapse who underwent (18)F-FCH PET/CT. At the time of (18)F-FCH PET/CT imaging, the mean PSA level was 46.9 ± 314.7 ng/mL and 55.2% (138/250) of patients were receiving ADT. Overall, ADT was performed on 67.2% (168/250) of patients after initial treatment. Imaging was performed on an integrated PET/CT system. Acquisition started 1 min after intravenous injection of (18)F-FCH (4.07 MBq/kg of body weight) with dynamic PET images in the pelvic region during 8 min (1 min/frame) followed by a static semi-whole-body acquisition. The final diagnosis of positive PET lesions was based on histopathology or a consensus of clinical findings, additional imaging, or follow-up imaging modalities. (18)F-FCH PET/CT was able to correctly detect malignant lesions in 74% (185/250) of patients but was negative in 26% (65/250). In 28% of patients, only 1 lesion was detected (69/250); from these, 65.2% (45 patients) had a local recurrence, 18.8% (13 patients) a single lymph node, and 15.9% (11 patients) a solitary bone metastasis. The sensitivity of the (18)F-FCH PET was significantly higher (P = 0.001) in patients with ongoing ADT (85%; confidence interval, 80%-91%) than in patients without ADT (59.5%; confidence interval, 50%-69%). (18)F-FCH PET sensitivity was 77.5%, 80.7%, 85.2%, and 92.8% for the trigger PSA levels of more than 0.5, 1.0, 2.0, and 4.0 ng/mL, respectively. Scan sensitivity was 33% in patients with a trigger PSA level of less than 0.3 ng/mL and 77% in patients with a

    2017-05-01

    PSA testing is widespread throughout Europe for diagnostic purposes and follow up. We performed a prospective outpatient cohort study of 250 men (2013-2015) in two hospital sites. Included were those men being followed up by urology with PSA blood testing. First appointments and those men in whom non-PSA tests were ordered by urology were excluded. The median age was 67.2yrs (46-88). Eighty-one point two percent of samples had a combination of 21 different serology tests at an added cost of >€18,000. Abnormal serology resulted in 53 referrals. Twenty-six-six percentof correspondence referenced abnormal serology other than PSA. Follow up of non-PSA test results poses a challenge in an outpatient setting with failure to appropriately follow-up on abnormal results, increased costs, and medico-legal implications. There is currently no Irish legislature in place to safeguard hospital physicians. This study quantifies the levels of expenditure, resources and risk associated with ambulant PSA testing.

    To determine whether there is a correlation between high Gleason score and free/total (f/t) prostate specific antigen (PSA) in patients newly diagnosed with prostate carcinoma. The study included 272 prostate biopsy patients whose total PSA value ranged from 4-10 ng/ml. The patients were divided into 2 groups according to the f/t PSA ratio: Group 1 ≤ 15% and Group 2 > 15%. Furthermore, the groups were also compared to each other in terms of mild (≤ 6), moderate (= 7), and high (≥ 8) Gleason score. Group 1 consisted of 135 (49.6%) patients and Group 2 consisted of 137 (50.4%) patients. While 27 (20%) patients had a high Gleason score in Group 1, only 10 (7.3%) patients had a high Gleason score in Group 2 (p = 0.008). Using Spearman's correlation test, we found that the f/t PSA ratios were observed to decrease significantly in all patients with increased Gleason scores (p = 0.002, r = -0.185). According to our study, there is a relationship between higher Gleason score and decreased f/t PSA ratio. Therefore, f/t PSA can be an indicator for predicting the Gleason score.

    Among the various research areas of the level 3 PSA, the effect of terrain on the transport of radioactive material was investigated through wind tunnel experiment. These results will give a physical insight in the development of a new dispersion model. Because there are some discrepancies between the results from Gaussian plume model and those from field test, the effect of terrain on the atmospheric dispersion was investigated by using CTDMPLUS code. Through this study we find that the model which can treat terrain effect is essential in the atmospheric dispersion of radioactive materials and the CTDMPLUS model can be used as a useful tool. And it is suggested that modification of a model and experimental study should be made through the continuous effort. The health effect assessment near the Yonggwang site by using IPE (Individual plant examination) results and its site data was performed. The health effect assessment is an important part of consequence analysis of a nuclear power plant site. The MACCS was used in the assessment. Based on the calculation of CCDF for each risk measure, it is shown that CCDF has a slow slope and thus wide probability distribution in cases of early fatality, early injury, total early fatality risk, and total weighted early fatality risk. And in cases of cancer fatality and population dose within 48km and 80km, the CCDF curve have a steep slope and thus narrow probability distribution. The establishment of methodologies for necessary models for consequence analysis resulting form a server accident in the nuclear power plant was made and a program for consequence analysis was developed. The models include atmospheric transport and diffusion, calculation of exposure doses for various pathways, and assessment of health effects and associated risks. Finally, the economic impact resulting form an accident in a nuclear power plant was investigated. In this study, estimation models for each cost terms that considered in economic

    Full Text Available Purpose. We investigated whether NS-RP increased risk of PSA failure and whether PSA should be included as a selection criterion for NS. Methods. We evaluated 357 consecutive men with screen-detected PC who underwent open RP without adjuvant radiotherapy between 9/11/2001 and 12/30/2008. Criteria for NS included Gleason score ≤3 + 4, percentage of positive biopsies (PPB ≤50%, percentage of core involvement ≤50%, nonapical location, no perineural invasion, and no palpable disease on pre- or intraoperative exam but did not include a PSA threshold. Cox multivariable regression assessed whether increasing PSA or unilateral- or bilateral-NS versus non-NS-RP was associated with PSA failure adjusting for prognostic factors. Results. After a median follow-up of 3.96 years, 34 men sustained PSA failure (9.5%. Increasing PSA was significantly associated with increased risk of PSA failure in the interaction model (adjusted hazard ratio (AHR: 1.09 [95% CI: 1.03–1.16]; P=0.005, whereas unilateral (AHR: 1.24 [95% CI: 0.36–4.34]; P=0.73 or bilateral NS (AHR: 0.41 [95% CI: 0.06–2.59]; P=0.34 versus non-NS RP was not. Conclusion. NS-RP in a screened cohort did not increase risk of PSA failure using NS criteria not including PSA.

    This report presents guidance for evaluation of Technical Specification conditions with PSA. It covers quality in PSA, how to verify that the PSA model is sufficiently robust and sufficiently complete and general requirements on methods. Acceptance criteria for evaluation of changes in the TS conditions are presented. As the probabilistic safety assessment (PSA) has developed over the years, it has demonstrated to constitute a useful tool for evaluating many aspects of the TS from a risk point of view. and in that way making the PSAs as well as the decision tools better. This also means that it will be possible to take credit for safety system overcapacity as well as inherent safety features and strength of non-safety classed systems. However, PSA is only one of the tools that shall be used in an evaluation process of TS changes (strengthening/relaxation). PSA is an excellent tool to be used to verify the importance, and thereby possibly relaxation, of TS requirements. But, since PSA is only one tool in the evaluation, it is not sufficient in itself for defining which equipment that shall or shall not have TS requirements. The purpose of this guidance document is to provide general requirements, requirements on methods and acceptance criteria on risk-informed evaluation of TS changes based on PSA. The purpose is not to provide a single solution. As part of the review of the TS conditions this guidance specify requirements on: - Quality verification of the PSA model; - Verification that the PSA model is sufficiently robust with regard to SSCs for which requirements both are and are not defined by the TS; - Verification that the SSCs, for which TS demands are to be evaluated, are modelled in a sufficient manner; - Methods for performing the evaluation; - Which evaluation criteria that shall be used (and how that is verified to be correct); - Acceptance criteria: This guidance also briefly discusses the documentation of the analysis of the TS changes.

    This paper describes the first laboratorial PSA (Pressure Swing Adsorption) unit designed and built in Brazil for gas separation by adsorption process. It consists of a stainless steel column, which was filled with zeolite 5A molecular sieve. Six solenoid valves located at the feed., product, countercurrent and high-pressure air lines were used to regulate the flow directions of different streams. Pressure and flowrate transducers and thermocouples were used to record respectively the pressure, flowrate of both feed and product stream and temperature history of the process. These instruments and the solenoid valves were joined to a programmable logic controller. By the use of a computer the unit can be automatically operated to simulate all steps in the PSA cycle and data can be easily acquired and recorded. The unit will be used to study basic parameters of PSA processes and to separate several gas mixtures. As a first goal the unit will be operated to produce oxygen-enriched air using synthetic zeolites. This PSA laboratory unit is an important step in CDTN`s objective of consolidating a research group in gas separation by adsorption processes. (author) 7 refs., 8 figs., 2 tabs.

    The provision of fish consumption advice issued by the Wisconsin Department of Health Services (DHS) and Department of Natural Resources (DNR) has evolved over the past 40 years. In 2010, DHS received a US Environmental Protection Agency Great Lakes Restoration Initiative (GLRI) grant to evaluate existing advisory approaches, identify gaps, and adapt current communication approaches. Previous research conducted by DHS found that older, male anglers eat more sport fish and have higher body burdens of persistent contaminants found in fish than other groups. As part of the GLRI, Wisconsin DHS and DNR aimed to engage this subpopulation and improve communication by using an Internet-based survey to collect information about fishing habits, consumption, and advisory awareness. At the end of the survey, participants were provided with answers to advisory questions and links to relevant online information. From fall 2011 through spring 2012, 827 men aged 50 and older completed this survey. Nearly all fishermen were aware of the existence of consumption advisories. Although awareness was high, penetration of traditional outreach materials was low with fewer than 35% having seen any of the pamphlets featured in the survey. Knowledge of the advisories was significantly higher among residents of counties along Lakes Michigan and Superior and among more frequent sport fish consumers. Men who were aware of these advisories were significantly more likely to have modified their consumption behavior. Wisconsin's experience suggests general awareness among older male anglers. Participation in the online survey and responses to sources of advisory information supports the need to expand the current outreach program to reach and inform the fish-consuming public.

All reported complications in early toxicity were grade 1. PSA density at time of diagnosis (p = 0.009, PSA on date of first HDR-BT (p = 0.033, and PSA on date of first follow-up after one year (p = 0.025 have statistical significance on a higher risk to get a local recurrence during follow-up. HDR-BT in combination with additional EBRT in the presented design for high-risk PCa results in high biochemical control rates with minimal side-effects. PSA is a negative predictive biomarker for local recurrence during follow-up. A longer follow-up is needed to assess long-term outcome and toxicities.

PSA density at time of diagnosis (p = 0.009), PSA on date of first HDR-BT (p = 0.033), and PSA on date of first follow-up after one year (p = 0.025) have statistical significance on a higher risk to get a local recurrence during follow-up. HDR-BT in combination with additional EBRT in the presented design for high-risk PCa results in high biochemical control rates with minimal side-effects. PSA is a negative predictive biomarker for local recurrence during follow-up. A longer follow-up is needed to assess long-term outcome and toxicities.

    To analyze the effect of the oral antidiabetic drug metformin on PSA level, free-to-total PSA ratio (f/t-ratio), PCa incidence and grade as well as mortality in men participating in a population-based screening trial. Data from 4,314 men aged 55-70 years from a population-based PSA-screening trial (ERSPC Aarau) were analyzed. Information on metformin exposure was obtained by a self-administered questionnaire. Serum PSA threshold at ≥3 ng/ml triggered prostate biopsy. Data on PCa incidence and mortality were obtained through registry linkages. Median follow-up time was 7.6 years. Mean age at baseline was 65.5 years (±SD 4.4). In all, n = 150 (3.5 %) men used metformin [metf+]. Mean baseline PSA levels were comparable between both groups ([metf+] 1.6 ng/ml ± 2.4 vs. [metf-] 1.8ug/l ± 2.2, p = 0.4) while f/t-ratio was slightly higher in metformin users ([metf+] 30.7 % ± 10.9 vs. [metf-] 27.3 % ± 10.9, p = 0.01). Overall, n = 372 (8.6 %) PCa cases were detected. Neither cumulative PCa incidence (n = 11; 7.3 % [metf+] vs. n = 361 8.7 % [metf-]; p = 0.5) nor d`Amico risk groups were significantly different between both groups. One man in each group (metf+ 0.7 % and metf- 0.02 %) died from PCa (p incidence and grade were observed. The slightly higher f/t-ratio did not result in lower PCa detection rate. Metformin users were at significantly higher risk of all-cause mortality. The relatively small number of men on metformin is a main limitation of the study.

    Combining risk factors for prostate cancer into a predictive tool may improve the detection of prostate cancer while decreasing the number of benign biopsies. We compare one such tool, age multiplied by prostate volume divided by total serum PSA (PSA-AV) with PSA density and detection of primary malignant circulating prostate cells (CPCs) in a Chilean prostate cancer screening program. The objectives were not only to determine the predictive values of each, but to determine the number of clinically significant cancers that would have been detected or missed. A prospective study was conducted of all men undergoing 12 core ultrasound guided prostate biopsy for suspicion of cancer attending the Hospital DIPRECA and Hospital de Carabineros de Chile. Total serum PSA was registered, prostate volumecalculated at the moment of biopsy, and an 8 ml blood simple taken immediately before the biopsy procedure. Mononuclear cells were obtained from the blood simple using differential gel centrifugation and CPCs identified using immunocytchemistry with anti- PSA and anti-P504S. Biopsy results were classed as positive or negative for cancer and if positive the Gleason score, number of positive cores and percent infiltration recorded. A total of 664 men participated, of whom 234 (35.2%) had cancer detected. They were older, had higher mean PSA, PSA density and lower PSA-AV. Detection of CPCs had high predictive score, sensitivity, sensibility and positive and negative predictive values, PSA-AV was not significantly different from PSA density in this population. The use of CPC detection avoided more biopsies and missed fewer significant cancers. In this screening population the use of CPC detection predicted the presence of clinically significant prostate cancer better than the other parameters. The high negative predictive value would allow men CPC negative to avoid biopsy but remain in follow up. The formula PSA-AV did not add to the predictive performance using PSA density.

    Full Text Available INTRODUCTION: Many studies have shown the association between PSA levels and the subsequent detection of prostate cancer. In the present trial, we have studied the relationship between preoperative PSA levels and clinical outcome following radical prostatectomy in men with clinical stage T1c. MATERIALS AND METHODS: 257 individuals with clinical stage T1c undergoing retropubic radical prostatectomy were selected in the period from 1991 to 2000. Following surgery, biochemical recurrence-free survival curves were constructed according to PSA levels between 0-4; 4.1-10; 10.1-20 and > 20 ng/mL. RESULTS: Of the total of 257 selected patients, 206 (80% had Gleason scores from 2 to 6 and 51 (20%, presented Gleason scores 7 and 8, as defined by the pathological report from prostate biopsy. There was no biochemical recurrence of disease when the PSA was lower than 4, regardless of Gleason score. Biochemical recurrence-free survival according to PSA between 0-4; 4.1-10; 10.1-20 and > 20 was 100%, 87.6%, 79% and 68.8% for Gleason scores 2-6 and 100%; 79.4%; 40% and 100% for Gleason scores 7-8 respectively. When all individuals were grouped, regardless of their Gleason scores, the probability of biochemical recurrence-free survival was 100%, 65.1%, 53.4% and 72.2% according to PSA between 0-4; 4.1-10; 10.1-20 and > 20 ng/mL respectively. CONCLUSION: Non-palpable prostate cancer presents higher chances of cure when the PSA is inferior to 4 ng/mL.

    Full Text Available Background: Multifocality, multicentricity and extension beyond the prostate capsule are all characteristics of prostatic adenocarcinoma that may escape diagnosis by conventional CT scanning or MRI. This study was designed to assess the diagnostic value of magnetic resonance spectroscopy (MRS in prostatic carcinoma and its compatibility with prostatic specific antigen (PSA as the conventional method.Methods: In this cross-sectional study, we recruited 139 patients with previous radical prostatectomy referring to Radiology department of Hazrate-e-Rasul Hospital during the first half of 2011 for the evaluation of local recurrence. Traditionally, local recurrence is defined as serum PSA concentration >0.2 ng/dl. We used 1.5-tesla Siemens Avanto MRI unit with endorectal coil and measured creatine, choline and citrate levels before calculating choline-creatine/citrate ratio. Correlation between MRS findings with PSA concentration was evaluated in regards to the multiple levels of the previously mentioned ratio.Results: Local recurrence was found in 107 (77% patients based on PSA levels. The mean values for serum PSA levels and creatine-choline/citrate ratio were significantly different in patients with and without local recurrence. Creatine-choline/citrate ratios greater than 50, 100 and 150 (as different cut-off points of recurrence were respectively seen in 104, 102 and 97 patients and agreement ratio between MRS and PSA in these levels were 94.1%, 94.4% and 85.1%, respectively. Correlation coefficient between these two methods was 0.481.Conclusion: MRS is a valuable tool for evaluating recurrence inpatients with prostate cancer treated by radical prostatectomy and it is in good agreement with serum PSA levels.

    The aim of this study was to evaluate the predictive role of percentage of free prostate-specific antigen (%fPSA) cut-points in prostate cancer (PCa) detection in patients with total PSA (tPSA) levels between 2.5 ng/mL and 10.0 ng/mL. In total, 1321 consecutive initial transrectal ultrasound (TRUS)-guided 12-core biopsies performed between 2005 and 2011 were evaluated retrospectively. Benign pathologies, high-grade prostatic intraepithelial neoplasia, and atypical small acinary proliferations were categorized as noncancerous (benign), and prostate adenocarcinomas were categorized as cancerous (malignant). The patients were categorized according to: Catalona's published %fPSA categories ( 25%); digital rectal examination (DRE) results [benign (negative) or suspicious of malignancy (positive)]. There was a significant relationship between the %fPSA cut-points and detection of PCa in DRE-negative patients. The presence of a 10% cut-point increased the probability of PCa threefold. The %fPSA was significantly more related to PCa than the tPSA value in receiver operating characteristic (ROC) curve analyses (p = 0.001). Based on our findings, a lower %fPSA, especially <10%, is an important parameter when deciding whether to perform a biopsy on patients with a tPSA between 2.5 ng/mL and 10 ng/mL. Copyright © 2015.

    The Planetary Science Archive (PSA) is the European Space Agency's (ESA) repository of science data from all planetary science and exploration missions. The PSA provides access to scientific datasets through various interfaces at http://psa.esa.int. All datasets are scientifically peer-reviewed by independent scientists, and are compliant with the Planetary Data System (PDS) standards. The PSA is currently implementing a number of significant improvements, mostly driven by the evolution of the PDS standard, and the growing need for better interfaces and advanced applications to support science exploitation. As of the end of 2016, the PSA is hosting data from all of ESA's planetary missions. This includes ESA's first planetary mission Giotto that encountered comet 1P/Halley in 1986 with a flyby at 800km. Science data from Venus Express, Mars Express, Huygens and the SMART-1 mission are also all available at the PSA. The PSA also contains all science data from Rosetta, which explored comet 67P/Churyumov-Gerasimenko and asteroids Steins and Lutetia. The year 2016 has seen the arrival of the ExoMars 2016 data in the archive. In the upcoming years, at least three new projects are foreseen to be fully archived at the PSA. The BepiColombo mission is scheduled for launch in 2018. Following that, the ExoMars Rover Surface Platform (RSP) in 2020, and then the JUpiter ICy moon Explorer (JUICE). All of these will archive their data in the PSA. In addition, a few ground-based support programmes are also available, especially for the Venus Express and Rosetta missions. The newly designed PSA will enhance the user experience and will significantly reduce the complexity for users to find their data promoting one-click access to the scientific datasets with more customized views when needed. This includes a better integration with Planetary GIS analysis tools and Planetary interoperability services (search and retrieve data, supporting e.g. PDAP, EPN-TAP). It will also be up

    Full Text Available Abstract Background Despite the recent publication of results from two randomized clinical trials, prostate specific antigen (PSA screening for prostate cancer remains a controversial issue. There is lack of agreement across studies that PSA screening significantly reduces prostate cancer mortality. In spite of these facts, the widespread use of PSA testing in the United States leads to overdetection and overtreatment of clinically indolent prostate cancer, and its associated harms of incontinence and impotence. Discussion Given the inconclusive results from clinical trials and incongruent PSA screening guidelines, the decision to screen for prostate cancer with PSA testing is an uncertain one for patients and health care providers. Screening guidelines from some health organizations recommend an informed decision making (IDM or shared decision making (SDM approach for deciding on PSA screening. These approaches aim to empower patients to choose among the available options by making them active participants in the decision making process. By increasing involvement of patients in the clinical decision-making process, IDM/SDM places more of the responsibility for a complex decision on the patient. Research suggests, however, that patients are not well-informed of the harms and benefits associated with prostate cancer screening and are also subject to an assortment of biases, emotion, fears, and irrational thought that interferes with making an informed decision. In response, the IDM/SDM approaches can be augmented with strategies from the philosophy of libertarian paternalism (LP to improve decision making. LP uses the insights of behavioural economics to help people better make better choices. Some of the main strategies of LP applicable to PSA decision making are a default decision rule, framing of decision aids, and timing of the decision. In this paper, we propose that applying strategies from libertarian paternalism can help with PSA

    2015-01-01

    Objective: Multiparametric MRI (mp-MRI) of the prostate is increasingly being used for local staging and detection of recurrence of prostate cancer (PCA). In patients with elevated prostate-specific antigen (PSA), mp-MRI could provide information on the position of the cancer, allowing adjustments to be made to the needle depth and direction before repeat transrectal ultrasound (TRUS)-guided biopsy to ensure accurate sampling of lesions. The purpose of the prospective study was to evaluate mp-MRI of the prostate in patients with PSA elevation before initial TRUS-guided biopsy. Methods: mp-MRI was performed in 94 patients using a 1.5-T scanner (MAGNETOM Aera®; Siemens Healthcare, Erlangen, Germany) and 16-channel phased-array body coil (Siemens Healthcare). T2 weighted images (T2WI), diffusion-weighted imaging (DWI), dynamic contrast-enhanced (DCE) MRI and MR spectroscopy were obtained. TRUS-guided random biopsies and additional targeted biopsies of suspicious MRI areas were performed. Results: Additional targeted biopsies were obtained in 17 of 43 (40%) patients with PCA. 11 of 17 targeted biopsies contained PCA. 5 of 11 PCAs were diagnosed only by additional targeted biopsies. Sensitivity of mp-MRI in patients was 97.7% and specificity was 11.8%. mp-MRI was false negative in one patient. Sensitivity of mp-MRI in 207 lesions was 80.9% and specificity was 44.7%. In a logistic regression model, the apparent diffusion coefficient value was the only significant parameter to differentiate malignant and benign lesions. Conclusion: mp-MRI should be performed in patients with PSA elevation before initial TRUS-guided biopsy to allow additional targeted biopsies from suspicious areas of MRI. We recommend mp-MRI with T2WI, DWI, DCE MRI and MR spectroscopy. DWI as the most reliable technique should be used in every mp-MRI. Advances in knowledge: DWI is the most reliable technique in mp-MRI of the prostate. PMID:26268144

    We previously reported the use of mass spectrometry and western blotting to identify proteins from tumour regions of formalin-fixed paraffin-embedded biopsies from 16 men who presented with apparently localized prostate cancer, and found that annexin A2 (ANXA2) appeared to be a better predictor of subsequent biochemical failure than prostate-specific antigen (PSA). In this follow-up study, ANXA2 and PSA were measured using western blotting of proteins extracted from biopsies from 37 men from a subsequent prostate cancer trial. No significant differences in ANXA2 and PSA levels were observed between men with and without biochemical failure. The statistical effect sizes were small, d=0.116 for ANXA2, and 0.266 for PSA. ANXA2 and PSA proteins measured from biopsy tumour regions are unlikely to be good biomarkers for prediction of the clinical outcome of prostate cancer presenting with apparently localized disease.

  18. Factors prompting PSA-testing of asymptomatic men in a country with no guidelines: a national survey of general practitioners.

    LENUS (Irish Health Repository)

    Drummond, Frances J

    2009-01-01

    BACKGROUND: Increased use of prostate specific antigen (PSA) has been associated with increased prostate cancer incidence. Ireland is estimated to have one of the highest prostate cancer incidences in Europe and has no national guidelines for prostate cancer screening. GPs have a pivotal role in influencing PSA testing, therefore, our aim was to describe GP testing practices and to identify factors influencing these. METHODS: A postal survey, including questions on clinical practice and experience, knowledge and demographics was distributed to all GPs (n = 3,683). The main outcomes were (i) PSA testing asymptomatic men and (ii) "inappropriate" PSA testing, defined as testing asymptomatic men aged < 50 or > 75 years. Factors associated with these outcomes were identified using logistic regression. RESULTS: 1,625 GPs responded (response rate corrected for eligibility = 53%). Most respondents (79%) would PSA test asymptomatic men. Of these, 34% and 51% would test asymptomatic men < 50 and > 75 years, respectively. In multivariate analyses, GPs were more likely to test asymptomatic men if they were >or= 50 years, in practice >or= 10 years, female or less knowledgeable about PSA efficacy. Male GPs who would have a PSA test themselves were > 8-times more likely to PSA test asymptomatic men than GPs who would not have a test. GPs who had an asymptomatic patient diagnosed with prostate cancer following PSA testing, were > 3-times more likely to test asymptomatic men. Practice-related factors positively associated with testing included: running \\'well man\\' clinics, performing occupational health checks and performing other tests routinely with PSA. Factors positively associated with \\'inappropriate\\' testing included; being male and willing to have a PSA test, having worked\\/trained in the UK and supporting annual PSA testing. 91% of respondents supported the development of national PSA testing guidelines. CONCLUSION: Our findings suggest that widespread PSA testing

    Early changes in PSA have been evaluated in association to treatment outcome. The aim of this study was to assess PSA surge phenomenon in castration-resistant prostate cancer (CRPC) patients treated with abiraterone and to correlate those variations with long-term treatment outcome. We retrospectively evaluated 330 CRPC patients in 11 Italian hospitals, monitoring PSA levels at baseline and every 4 weeks. Other clinical, biochemical and molecular parameters were determined at baseline. We considered PSA surge as PSA increase within the first 8 weeks from starting abiraterone more than 1% from baseline followed by a PSA decline. The log-rank test was applied to compare survival between groups of patients according to PSA surge. The impact of PSA surge on survival was evaluated by Cox regression analyses. A total of 330 patients with CRPC, median age 74 years (range, 45-90), received abiraterone (281 chemotherapy-treated and 49 chemotherapy-naïve). PSA surge was observed in 20 (7%) post-chemotherapy and 2 (4%) chemotherapy-naïve patients. For overall patients presenting PSA surge, timing of PSA peak from baseline was 5 ± 1.8 weeks and PSA rise from baseline was 21 ± 18.4%. The overall median follow-up was 23 months (range 1-62). No significant differences in progression-free survival and overall survival were observed between patients with and without PSA surge (P = 0.16 and =0.86, respectively). In addition, uni- and multivariate analyses showed no baseline factors related to PSA surge. PSA surge occurs in both chemotherapy-treated and chemotherapy-naïve patients treated with abiraterone resulting, however, in no long-term impact on outcome. Physicians and patients should be aware of PSA surge challenge to prevent a premature discontinuation of potentially effective therapy with abiraterone. Further larger and prospective studies are warranted to investigate this not infrequent phenomenon. © 2017 Wiley Periodicals, Inc.

    Medical students face pressures ranging from the need to create a social network to learning vast amounts of scientific material. Students often feel isolated in this system and lack mentorship. In order to counteract feelings of bureaucratic anonymity and isolation, the University of California San Francisco has created an advisory college to foster the professional and personal growth and well being of students. UCSF has developed a formal structure to advise medical students. A selection committee, chaired by the associate dean of student affairs, appointed five faculty mentors to head advisory colleges. These five colleges serve as the advising and well-being infrastructure for the students. Mentors were chosen from a balanced range of clinical disciplines, both primary and specialty. The disciplines are obstetrics-gynecology, otolaryngology/head and neck surgery, medicine, pediatrics, and psychiatry. The mentors have demonstrated excellence in advising and counseling of students. Mentors meet individually at the beginning of the academic year with incoming first-year and second-year students. They then have bimonthly meetings with eight to ten students within each college throughout the academic year. Curricula for these group sessions include well-being discussions and coping techniques, sessions on the hidden and informal curriculum of professionalism, and discussions on career choices and strategies. For third-year students, advisory college meetings are scheduled during intersessions, which are weeklong courses that occur between the eight-week clerkship blocks. Mentors are available throughout the year to meet with students on an as-needed basis, and advisory colleges may hold group social activities. The dean's office supports each mentor with 20% salary and provides administrative support for the group college activities. Historically, UCSF students feel they receive an excellent education and appropriate job opportunities, but they do not feel they

    Full Text Available Objectives: To evaluate associations of preoperative total prostate specific antigen (PSA to free testosterone (FT, the PSA/FT index ratio, with features of pathology prostate cancer (PCA and to investigate its prognostic potential in clustering the PCA population. Patients and methods: After excluding criteria, the records of 220 patients who underwent radical prostatectomy (RP were retrospectively reviewed. Serum samples of PSA, total testosterone (TT and FT were collected at 8.00 A.M., one month after biopsies and before RP. The PSA/FT ratio was computed in the population of patients who were clustered in groups according to ranking intervals of the PSA/FT ratio which identified at least 4 clusters which were coded as A, B, C, and D. The independent associations of the PSA/FT index ratio were assessed by statistical methods and a two-sided P < 0.05 was considered to indicate statistical significance. Results: TT correlated to FT which was a significant predictor of PSA in the population of patients who were subsequently clustered, according to increasing interval values of the PSA/FT index ratio, in groups that showed a stronger linear association of FT with PSA. The PSA/FT index ratio significantly associated with pathology features of prostate cancer such as pathology Gleason score (pGS, invasion of the seminal vesicles (pT3b, proportion of positive cores (P+ and proportion of cancer involving the volume of the prostate.

    The reactor facility probabilistic safety analysis methodologies are considered which are used at U.S. LANL and RF NIKIET. The methodologies are compared in order to reveal their similarity and differences, determine possibilities of using the LANL technique for RBMK type reactor safety analysis. It is found that at the PSA-1 level the methodologies practically do not differ. At LANL the PHA, HAZOP hazards analysis methods are used for more complete specification of the accounted initial event list which can be also useful at performance of PSA for RBMK. Exchange of information regarding the methodology of detection of dependent faults and consideration of human factor impact on reactor safety is reasonable. It is accepted as useful to make a comparative study result analysis for test problems or PSA fragments using various computer programs employed at NIKIET and LANL.

    The study of genes involved in androgen pathway can contribute to a better knowledge of prostate cancer. Our aim was to examine if polymorphisms in prostate-specific antigen (PSA) and androgen receptor (AR) genes were involved in prostate cancer risk and aggressiveness. Genotypes were determined...... by PCR-RFLP (PSA) or using a 377 ABI DNA Sequencer (AR). PSA(G/G) genotype (OR = 1.78, 95% CI = 1.06–2.99) and AR short CAG repeats (OR = 1.89, 95% CI = 1.21–2.96) increased risk for prostate cancer and were related with tumor aggressiveness. About 38.3% of tumors showed microsatellite instability...

    Positive surgical margins (PSM) are an important determinant of biochemical recurrence after radical prostatectomy (RP). We use a population-based cancer registry to evaluate PSM by stage, Gleason and prostate-specific antigen (PSA). We identified men undergoing RP from the Surveillance, Epidemiology and End Results (SEER) database between 2004 and 2007. Differences between those with and without PSM were compared with chi-squared tests. The proportion of cases with PSM were stratified by PSA and Gleason sum for both pT2 and pT3a tumours. Factors associated with PSM were analyzed using chi square and multivariate logistic regression analysis. A composite variable was used in a second multivariate analysis to display the odds ratio (OR) for a PSM for each discrete combination of PSA, Gleason score and pT stage. In total, 28 461 RP patients were identified and a PSM was present in 19.5%. PSM were 42% in pT3a and 16% in pT2 cases. Higher PSAs (10) were associated with higher proportions of PSM (12%, 20% and 28%, p strata compared to those with pT2 tumours, reaching 63% for those with pT3a, Gleason 8-10, PSA >10 disease. On multivariate analysis, stage was the largest predictor for PSM (OR 3.05, 95% confidence interval 2.81-3.30), although Gleason score and PSA remained statistically significant. In this population-based study of PSM after RP, the proportion of PSM vary significantly within different PSA and Gleason strata for organ-confined and extracapsular disease. These data can be used as a reference for urologist self-assessment.

  7. Literature Survey on Technical Issues and Insights of Multi-Unit PSA

    The need consider the risk impact in case of multi-unit in a single site increased after the accident at Fukushima Daiichi in March 2011. This means that we have to consider the single-unit initiators impacting the other units and the simultaneous accidents of the multi-unit on the same site. Particularly, this kind of technical concern is serious in case of the Republic of Korea where multi-units had to be located in high-density population area due to geographical features. The Nuclear Safety and Security Commission (NSSC) in the Republic of Korea has been trying to identify the state of the art of international and domestic regulations and techniques on multi-unit risk assessment and planning the road map for the safety researches. However, we have to say that finding a common accepted methodology along with safety criteria for multi-unit PSA was not an easy task up to now. This paper summarizes and analyzes related international and domestic journals' papers, conferences' papers and reports about the multi-unit PSA classifying categories with themes to understand the technical tendency of multi-unit PSA. In addition, some insights that were obtained from this classification have been arranged too. This paper investigated the technical trend of the multi-unit PSA as collecting of the international and domestic journals' papers, conferences papers and reports, and analyzing them. Upon the literature survey, a few statistics, technical issues, and insights were summarized. Both of the fundamental and practical researches need to find a globally accepted methodology to calculate and determine quantitative objectives for a multi-unit PSA. We want to expect that this paper can be shared to understand the current status of multi-unit PSA.

  8. Metastatic Prostate Cancer Diagnosed by Bone Marrow Aspiration in an Elderly Man Not Undergoing PSA Screening

    Full Text Available Prostate cancer screening by PSA testing remains controversial, particularly in the elderly. Practice guidelines from most clinical societies suggest discontinuing PSA screening at age 70 while the USPSTF recommends against screening at any age. Recent reports have demonstrated an increased incidence of metastatic prostate cancer, with men aged 75 or older accounting for roughly half of those newly diagnosed at an incurable stage. We herein describe the case of an elderly gentleman with no history of prostate cancer screening who presented with anorexia and back pain of unclear etiology. Evaluation with bone marrow aspiration revealed a diagnosis of metastatic prostate cancer.

    Prospective analysis of results of combined neo-adjuvant hormonotherapy and external beam radiation therapy in A2-B2 prostate adenocarcinoma. Between 1986 and 1994, 36 patients with clinical stage A2 (five patients), B1 (12 patients) and B2 (19 patients) N0 adenocarcinoma of the prostate declined for radical surgery, underwent a brief neo-adjuvant hormonal therapy before external beam radiotherapy at our radiation therapy department. They all had a PSA determination before the combined treatment and no evidence of local extension or metastatic spread. They were followed clinically and with serial PSA levels for a median time of 58 months. Relapse was defined by a PSA level {>=}2.5 ng/mL. Median pre-treatment PSA level was 16.5 ng/mL; 16 patients had less than 15 ng/mL. Combined treatment was very well tolerated. After 3 months of neo-adjuvant hormonotherapy, digital rectal examination was normalized in 27 cases with a PSA value {<=} 1 ng/mL in 23. Only four tumors have relapsed (one local failure, two metastases and one PSA failure). The single factor that predicted biochemical relapse was pre-treatment PSA level: the 5-year actuarial rate of PSA failure when PSA level < 15 ng/ml was 0% and 27.5% if it was {>=} 15 ng/mL (p = 0.05). During follow- up only two patients suffered grade 2 rectitis and seven complained a total impotency. This limited study advocates hormonal neo-adjuvant therapy and radiotherapy association in intra-capsular prostatic carcinoma in patients declined for surgery or when pre-treatment PSA is above 15 ng/mL, with mild acute and late toxicity.

    In this study, the communication of PSA information in nuclear power plants (NPPs), namely, how the risk information obtained from the probabilistic safety assessment (PSA) should be presented and communicated to plant personnel, was examined assuming that the safety management system based on the risk information was introduced to NPPs. This is called PSA communication. First, when risk-informed safety management is to be introduced into NPPs, plant personnel should have sufficient related knowledge. In order to provide such knowledge to the personnel through training, risk information is classified into three types: basic information, detailed information and task information. A hierarchical risk information summary for reporting, coordinating and communicating tasks is proposed. In this summary, the concerns of those who have received the information are placed at the top and the related risk information positioned below. At the same time, and by way of a trial, the risk information relating to on-line maintenance (OLM) is prepared. In order to enhance the safety-consciousness and the safety of the entire plant, specific plans such as 'risk tags' which indicate the safety significance of equipment is proposed. Finally, a guideline providing examination procedures for developing detailed PSA communication plans is introduced. (author)

    Full Text Available Probabilistic Safety Assessment (PSA has been widely used to estimate the overall safety of nuclear power plants (NPP and it provides base information for risk informed application (RIA and risk informed regulation (RIR. For the effective and correct use of PSA in RIA/RIR related decision making, the risk estimated by a PSA model should be as realistic as possible. In this work, a best-estimate thermal-hydraulic analysis of loss-of-coolant accidents (LOCAs for the Hanul Nuclear Units 3&4 is first carried out in a systematic way. That is, the behaviors of peak cladding temperature (PCT were analyzed with various combinations of break sizes, the operating conditions of safety systems, and the operator's action time for aggressive secondary cooling. Thereafter, the results of the thermal-hydraulic analysis have been reflected in the improvement of the PSA model by changing both accident sequences and success criteria of the event trees for the LOCA scenarios.

    Given that screening for prostate cancer has the potential to reduce prostate cancer mortality at the expense of considerable overdiagnosis and overtreatment, the availability of core consumer information - correct, balanced and supportive of autonomous decision-making - is a must. We assessed the quality of consumer information available through the Internet per November 2009 and its possible contribution to informed decision-making by potential screenees. Consumer information on PSA-screening was sought through the Internet in November 2009. Materials had to be targeted at potential consumers, offered by not-for-profit organisations, released in 2005 or after, in English or Dutch. Per material 2 of the authors assessed independently from each other whether standardised pre-defined topics were addressed, whether the content was correct and which approach was taken towards the decision-making process about uptake. Twenty-three materials were included, of which 11 were released (shortly) after the results of 2 large randomized-controlled trials (RCTs) that evaluated the effectiveness of screening for prostate cancer had been published in March 2009. That a PSA-test result can be abnormal because of non-cancerous conditions (false positive) and that it may miss prostate cancer (false negative) was not addressed in 2/23 and 8/23 materials, respectively. The risk of overdiagnosis and overtreatment was not mentioned in 6 out of 23. PSA-screening was presented as a usual thing to do in some materials, whereas other materials emphasised the voluntary nature of PSA-screening ('it is your decision'). The content of 19/23 materials was considered sufficiently informative according to the pre-defined criteria, 12/23 materials were considered supportive of informed decision-making by men. Most materials of not-for-profit organizations supplied adequate information about PSA-screening, whilst the degree of persuasion towards uptake reflected variations in opinions on men

    members of an Amazon community, as well as its possible relationship to acculturation and overweight (body mass index. METHODS: Lifestyle and anthropometric information was collected from a group of 22 men, presumedly over age 50, members of an isolated community of 363 Amazonian Indians - self-denominated Parkatejê and Kykatêjê - from Pará state, in Northern Brazil. In addition to physical and hematological exams, total and free PSA dosages were performed. RESULTS: Total PSA serum levels ranged from 0.35 to 25.8 ng/ml. Three subjects had PSA levels greater than 4.0 ng/ml, and another two had levels between 2.5 and 4.o ng/ml. Prostate biopsies performed on two subjects indicated the presence of prostate adenocarcinoma in one of them and of intraepithelial neoplasia on the other. Overweight (BMI >25 Kg/m² and waist-to-hip ratio >0,9 were observed in 68.1% and 72% of subjects, respectively. CONCLUSIONS: Changes in nutritional habits caused by contact with civilization, such as the substitution of more caloric foods for the traditional game and vegetable fiber are increasing the prevalence of overweight among the community. In view of the association between prostate cancer incidence, high-fat diet, and less physical activity, it can be assumed that further cases of prostate neoplasia will occur in the future, since several community members already have high PSA serum levels.

    Prostate Specific Antigen (PSA) is widely used as a biomarker for prostate cancer. Recently, an electrochemical biosensor for PSA detection by means of molecularly imprinted polymers (MIPs) was developed. This work evaluated the performance and the effectiveness of that PSA biosensor in screening the biomarker PSA in biological media with complex composition, collected from different human prostate cell line cultures. For that, the prostate cancer LNCaP and PC3 cells, and the non-cancerous prostate cell line PNT2 were cultured for 2, 7 and 14 days in either α-MEM or RPMI in the presence of 10% or 30% fetal bovine serum. Human gingival fibroblasts were used as a non-cancerous non-prostatic control. The different culture conditions modulated cellular proliferation and the expression of several prostate markers, including PSA. The electrochemical biosensor was able to specifically detect PSA in the culture media and values obtained were similar to those achieved by a commercial Enzyme-Linked Immunosorbent Assay (ELISA) kit, the most commonly used method for PSA quantification in prostate cancer diagnosis. Thus, the tested biosensor may represent a useful alternative as a diagnostic tool for PSA determination in biological samples. - Highlights: • PSA quantification was performed in prostate cancer cell culture media. • Culture media composition and culture period significantly affect PSA production. • The PSA biosensor detected a wide range of PSA levels in complex media. • A high data correlation was observed between the biosensor and the ELISA analysis.

    To examine the relationship between the extent of disease determined by [{sup 68}Ga]PSMA-HBED-CC-PET/CT and the important clinical measures prostate-specific antigen (PSA), PSA doubling time (PSAdt) and Gleason score. We retrospectively studied the first 155 patients with recurrent prostate cancer (PCA) referred to our university hospital for [{sup 68}Ga]PSMA-HBED-CC PET/CT. PET/CT was positive in 44 %, 79 % and 89 % of patients with PSA levels of ≤1, 1 - 2 and ≥2 ng/ml, respectively. Patients with high PSA levels showed higher rates of local prostate tumours (p < 0.001), and extrapelvic lymph node (p = 0.037) and bone metastases (p = 0.013). A shorter PSAdt was significantly associated with pelvic lymph node (p = 0.026), extrapelvic lymph node (p = 0.001), bone (p < 0.001) and visceral (p = 0.041) metastases. A high Gleason score was associated with more frequent pelvic lymph node metastases (p = 0.039). In multivariate analysis, both PSA and PSAdt were independent determinants of scan positivity and of extrapelvic lymph node metastases. PSAdt was the only independent marker of bone metastases (p = 0.001). Of 20 patients with a PSAdt <6 months and a PSA ≥2 ng/ml, 19 (95 %) had a positive scan and 12 (60 %) had M1a disease. Of 14 patients with PSA <1 ng/ml and PSAdt >6 months, only 5 (36 %) had a positive scan and 1 (7 %) had M1a disease. [{sup 68}Ga]PSMA-HBED-CC PET/CT will identify PCA lesions even in patients with very low PSA levels. Higher PSA levels and shorter PSAdt are independently associated with scan positivity and extrapelvic metastases, and can be used for patient selection for [{sup 68}Ga]PSMA-HBED-CC PET/CT. (orig.)

    The antibody microarrays have become widespread, but their use for quantitative analyses in clinical samples has not yet been established. We investigated an immunoassay based on nanoporous silicon antibody microarrays for quantification of total prostate-specific-antigen (PSA) in 80 clinical plasma samples, and provide quantitative data from a duplex microarray assay that simultaneously quantifies free and total PSA in plasma. To further develop the assay the porous silicon chips was placed into a standard 96-well microtiter plate for higher throughput analysis. The samples analyzed by this quantitative microarray were 80 plasma samples obtained from men undergoing clinical PSA testing (dynamic range: 0.14-44 ng/ml, LOD: 0.14 ng/ml). The second dataset, measuring free PSA (dynamic range: 0.40-74.9 ng/ml, LOD: 0.47 ng/ml) and total PSA (dynamic range: 0.87-295 ng/ml, LOD: 0.76 ng/ml), was also obtained from the clinical routine. The reference for the quantification was a commercially available assay, the ProStatus PSA Free/Total DELFIA. In an analysis of 80 plasma samples the microarray platform performs well across the range of total PSA levels. This assay might have the potential to substitute for the large-scale microtiter plate format in diagnostic applications. The duplex assay paves the way for a future quantitative multiplex assay, which analyzes several prostate cancer biomarkers simultaneously. Copyright © 2012 Elsevier B.V. All rights reserved.

  1. Effects of cyclic adenosine-monophosphate on growth and PSA secretion of human prostate cancer cell line.

    Science.gov (United States)

    Macchia, V; Di Carlo, A; De Luca, C; Mariano, A

    2001-05-01

    Prolonged increase of cyclic adenosine-monophosphate (cAMP) level in the culture medium of a well differentiated human prostatic cancer cell (LNCaP) inhibits cellular growth and stimulates PSA secretion. The differentiation of the cells tested was documented by their responsiveness to androgens and the ability to synthesize cellular markers of differentiation (PSA). The raise in cAMP level was produced by dibutyryl cyclic AMP (DBcAMP) or by agents acting at distinct levels in the pathway of cAMP generation (forskolin) or degradation (IBMX). Each of these three agents in a range of concentrations between 10-4-10-6 M had an inhibitory effect on the growth which is dose and time-dependent. The inhibition was reversible as demonstrated by complete restoration of cell growth soon after the withdrawal of the substances from the culture medium. When cAMP levels in culture medium was raised, an increase in PSA content was observed. However, the effects of cAMP on PSA content was not due to increase in PSA synthesis, since simultaneous measurement of secreted and cellular PSA indicated that the principal effect of the cyclic nucleotide was to enhance the secretion of stored PSA. Furthermore the inhibition of cellular growth by cAMP suggests new approaches in prostatic carcinoma therapy.

    Prostate specific antigen (PSA) test is the most common, clinically validated test for the diagnosis of prostate cancer (PCa). While neoplastic lesions of the prostate may cause aberrant levels of PSA in the blood, the quantitation of free or complexed PSA poorly discriminates cancer patients from those developing benign lesions, often leading to invasive and unnecessary surgical procedures. Microenvironmental acidity increases exosome release by cancer cells. In this study we evaluated whether acidity, a critical phenotype of malignancy, could influence exosome release and increase the PSA expression in nanovesicles released by PCa cells. To this aim, we exploited Nanoparticle Tracking Analysis (NTA), an immunocapture-based ELISA, and nanoscale flow-cytometry. The results show that microenvironmental acidity induces an increased release of nanovesicles expressing both PSA and the exosome marker CD81. In order to verify whether the changes induced by the local selective pressure of extracellular acidity may correspond to a clinical pathway we used the same approach to evaluate the levels of PSA-expressing exosomes in the plasma of PCa patients and controls, including subjects with benign prostatic hypertrophy (BPH). The results show that only PCa patients have high levels of nanovesicles expressing both CD81 and PSA. This study shows that tumor acidity exerts a selective pressure leading to the release of extracellular vesicles that express both PSA and exosome markers. A comparable scenario was shown in the plasma of prostate cancer patients as compared to both BPH and healthy controls. These results suggest that microenvironmental acidity may represent a key factor which determines qualitatively and quantitatively the release of extracellular vesicles by malignant tumors, including prostate cancer. This condition leads to the spill-over of nanovesicles into the peripheral blood of prostate cancer patients, where the levels of tumor biomarkers expressed by

    By this first assay realized during two years, the authors wanted to assess the diagnostic performances of radioimmunoassay P.S.A., still unknown by Ivorian prescribers. It was about 78 patients who presented prostatic affections confirmed by histology. The dosages showed that, in prostate adenoma, a P.S.A. level was 9.5 ng/ml with P.S.A. density (P.S.A.D.) at 0.3. In prostate cancer, a P.S.A. level at 64.9 ng/ml with P.S.A.D. at 1.68. P.S.A. sensibility was good (91%) in spite of the value used, its specificity was about 94% for a level of 20 ng/ml. The predictive positive value was excellent with 20 ng/ml (95%). The risk to have prostate cancer with P.S.A. level of 10 ng/ml was 73.8% when rectal route (R.R.) was abnormal. The risk was low to 14.28% when the R.R. was normal. The radioimmunoassay of P.S.A. and P.S.A.D. rate improved significantly diagnostic indications in prostatic affections. Consequently, it must form part of first-line examination to the health assessment of old patients for a better prostatic lesions management. (authors)

  16. Predictive simulations and optimization of nanowire field-effect PSA sensors including screening

    KAUST Repository

    Baumgartner, Stefan

    2013-05-03

    We apply our self-consistent PDE model for the electrical response of field-effect sensors to the 3D simulation of nanowire PSA (prostate-specific antigen) sensors. The charge concentration in the biofunctionalized boundary layer at the semiconductor-electrolyte interface is calculated using the propka algorithm, and the screening of the biomolecules by the free ions in the liquid is modeled by a sensitivity factor. This comprehensive approach yields excellent agreement with experimental current-voltage characteristics without any fitting parameters. Having verified the numerical model in this manner, we study the sensitivity of nanowire PSA sensors by changing device parameters, making it possible to optimize the devices and revealing the attributes of the optimal field-effect sensor. © 2013 IOP Publishing Ltd.

    In response to public concern about the cleanup of the Three Mile Island, Unit 2 (TMI-2) facility after an accident on March 28, 1979 involving a loss of reactor coolant and subsequent damage to the reactor fuel, twelve citizens were asked to serve on an independent Advisory Panel to consult with the Nuclear Regulatory Commission (NRC) on the decontamination and cleanup of the facility. The panel met 78 times over a period of thirteen years, holding public meetings in the vicinity of TMI-2 and meeting regularly with NRC Commissioners in Washington, DC. This report describes the results of a project designed to identify and describe the lessons learned from the Advisory Panel and place those lessons in the context of what we generally know about citizen advisory groups. A summary of the empirical literature on citizen advisory panels is followed by a brief history of the TMI-2 Advisory Panel. The body of the report contains the analysis of the lessons learned, preliminary conclusions about the effectiveness of the Panel, and implications for the NRC in the use of advisory panels. Data for the report include meeting transcripts and interviews with past and present Panel participants.

    The OECD/NEA CSNI Working Group on Risk Assessment (WGRisk) has set up a task group called DIGREL to develop a taxonomy of failure modes of digital components for the purposes of probabilistic safety assessment (PSA). A parallel Nordic activity carried out a pre-study where a comparison of Nordic experiences and a literature review were performed. The study showed a wide range of approaches and solutions to the challenges given by digital I and C. In 2011, a proposal for the failure modes taxonomy was defined. This is based on a set of requirements agreed on the purpose of the taxonomy. The following levels of details can be distinguished from the hardware point of view: (1) the entire system, (2) a division, (3) processing units (and cabinets), (4) modules, i.e. subcomponents of processing units and (5) generic components, i.e. subcomponents of modules. Module level seems to be the most appropriate from the PSA modelling point of view. The software failure modes taxonomy is still an open issue. An existing simplified PSA model has been complemented with fault tree models for a four-redundant distributed protection system in order to study and demonstrate the effect of design features and modelling approaches. The example shows that even rather simple I and C design leads to rather complex model despite of the fact that many things have been simplified and only a few protection signals are considered. One lesson from the example is that the Alpha factor model should be used to model common cause failures instead of the Beta factor model. Two options were developed to the comparison of different fail-safe principles. The role of detectable and undetectable failure modes with respect to the failed versus spurious actuations can be clearly seen in the results, showing the importance to model these features in PSA.

  9. Galectin-3 Is a Substrate for Prostate Specific Antigen (PSA) in Human Seminal Plasma

    Background Galectin-3 is a multivalent carbohydrate-binding protein involved in cell adhesion, cell cycle control, immunomodulation, and cancer progression, including prostate cancer. Galectin-3 function is regulated by proteolytic cleavage that destroys galectin-3 multivalency while preserving carbohydrate-binding activity. In human semen, galectin-3 is present in seminal plasma and is also associated with prostasomes, exosome-like vesicles secreted by the prostate. In the current study, we characterized the proteolytic activity that cleaves galectin-3 in human seminal plasma. Methods An in vitro assay was developed to investigate galectin-3 cleavage in seminal plasma. The effect of protease inhibitors, divalent ion chelators, and Zn2+ on the cleavage activity was determined. Proteases enriched from seminal plasma were tested for their ability to cleave galectin-3. Affinity purification and microsequence analysis were used to identify the cleavage site in galectin-3. Results Galectin-3 was identified in human seminal plasma in an intact and truncated form. Gelatinases enriched from seminal plasma did not cleave galectin-3. Inhibitor studies indicated that the galectin-3 cleavage activity in seminal plasma is a Zn2+ sensitive, serine protease. Prostate specific antigen (PSA) was demonstrated to cleave galectin-3 between tyrosine107-glycine108 and produce a functionally-active, monovalent lectin. Conclusions PSA is a chymotrypsin-like serine protease secreted by the prostatic epithelium and normally functions in liquefaction of semen following ejaculation. Furthermore, PSA is implicated in the promotion of localized prostate tumors and bone metastases by its roles in immunomodulation, invasion, and apoptosis. Our results indicate that PSA regulates galectin-3 in human semen and may regulate galectin-3 function during prostate cancer progression. PMID:20672323

    The common tool for diagnosing prostate cancer is prostate-specific antigen (PSA), but the high sensitivity and low specificity of PSA testing are the problems in clinical practice. There are no proper guidelines to investigate the suspected prostate cancer in the Cayman Islands. We correlated PSA levels with the incidence of prostate cancers by tissue diagnosis and proposed logical protocol for prostate screening by using PSA test in this small population. A total of 165 Afro Caribbean individuals who had prostate biopsy done after the investigations for PSA levels from year 2005 to 2015 were studied retrospectively. The patients were divided into subgroups by baseline PSA levels as follows: 100 ng/mL and were correlated to the age and presence of cancer. Benign lesions had lower PSA levels compared to cancer which generally had higher values. Only three cases that had less than 4 ng/mg were turned out to be malignant. When PSA value was more than 100 ng/mL, all the cases were malignant. Between PSA values of 4-100 ng/mL, the probability of cancer diagnosis was 56.71% (76 cancers out of 134 in this range). Limitation of PSA testing has the risk of over diagnosis and the resultant negative biopsies owing to poor specificity. Whereas the cutoff limit for cancer diagnosis still remains 4 ng/mL from our study, most of the patients can be assured of benign lesion below this level and thus morbidity associated with the biopsy can be prevented. When the PSA value is greater than 100 ng, biopsy procedure was mandatory as there were 100% cancers above this level. On the background of vast literature linking PSA to prostate cancer and its difficulty in implementing in clinical practice, we studied literature of this conflicting and complex topic and tried to bring relevant protocols to the small population of Cayman Islands for the screening of prostate cancer. In this study, a total of 165 Afro Caribbean individuals who had prostate biopsy done after the

Wir haben es jetzt mit einem "bio-chemisch Kranken" zu tun, bei dem nicht selten kein lokales Rezidivgeschehen und schon gar nicht eine Fernmetastasierung nachgewiesen werden kann. Um zwischen der lokalen und systemischen Erkrankung unterscheiden zu können, hat man sich früher der "pathohistologischen Prädiktion" bedient. Hierauf beruht auch ein großer Teil der häufig eingesetzten Nomogramme. Mit der Bestimmung der PSA-DT ist eine Methode in das diagnostische Repertoire aufgenommen worden, die nach weiterer Evaluierung dazu dienen könnte, lokale Maßnahmen (RT nach RP oder Salvage-Prostatektomie, HIFU bzw. Kryotherapie oder eine Androgendeprivation vorzunehmen. Vieles deutet darauf hin, daß wir in Zukunft nicht nur mit einer Berechnung der PSA-DT die lokale von der systemischen Progression unterscheiden können, sondern auch das Übergangsstadium zur klinischen Metastasenerkrankung voraussagen und das Risiko, am Prostatakrebs zu sterben, einschätzen können.

    2011 Fukushima nuclear power plant severe accident was caused by both earthquake and tsunami, which results in large amount of radioactive nuclides release. That accident has caused the radioactive contamination on the surrounding environment. Although this accident probability is extremely small, once such an accident happens that is likely to release a lot of radioactive materials into the environment, and cause radiation contamination. Therefore, studying accidents consequences is important and essential to improve nuclear power plant design and management. Level 3 PSA methods of nuclear power plant can be used to analyze radiological consequences, and quantify risk to the public health effects around nuclear power plants. Based on multiple external hazards compound level 3 PSA methods studies of nuclear power plant, and the description of the multiple external hazards compound level 3 PSA technology roadmap and important technical elements, as well as taking a coastal nuclear power plant as the reference site, we analyzed the impact of off-site consequences of nuclear power plant severe accidents caused by multiple external hazards. At last we discussed the impact of off-site consequences probabilistic risk studies and its applications under multiple external hazards compound conditions, and explained feasibility and reasonableness of emergency plans implementation.

    Binary decision diagrams are a well-known alternative to the minimal cutsets approach to assess the reliability Boolean models. They have been applied successfully to improve the fault trees models assessment. However, its application to solve large models, and in particular the event trees coming from the PSA studies of the nuclear industry, remains to date out of reach of an exact evaluation. For many real PSA models it may be not possible to compute the BDD within reasonable amount of time and memory without considering the truncation or simplification of the model. This paper presents a new approach to estimate the exact probabilistic quantification results (probability/frequency) based on combining the calculation of the MCS and the truncation limits, with the BDD approach, in order to have a better control on the reduction of the model and to properly account for the success branches. The added value of this methodology is that it is possible to ensure a real confidence interval of the exact value and therefore an explicit knowledge of the error bound. Moreover, it can be used to measure the acceptability of the results obtained with traditional techniques. The new method was applied to a real life PSA study and the results obtained confirm the applicability of the methodology and open a new viewpoint for further developments.

    Full Text Available Abstract Background Informed decision making is the theoretical basis in the UK for men's decisions about Prostate Specific Antigen (PSA testing for prostate cancer testing. The aim of this study is to evaluate the effect of a web-based PSA decision-aid, Prosdex, on informed decision making in men. The objective is to assess the effect of Prosdex on six specific outcomes: (i knowledge of PSA and prostate cancer-related issues – the principal outcome of the study; (ii attitudes to testing; (iii decision conflict; (iv anxiety; (v intention to undergo PSA testing; (vi uptake of PSA testing. In addition, a mathematical simulation model of the effects of Prosdex will be developed. Methods A randomised controlled trial with four groups: two intervention groups, one viewing Prosdex and the other receiving a paper version of the site; two control groups, the second controlling for the potential Hawthorn effect of the questionnaire used with the first control group. Men between the ages of 50 and 75, who have not previously had a PSA test, will be recruited from General Practitioners (GPs in Wales, UK. The principal outcome, knowledge, and four other outcome measures – attitudes to testing, decision conflict, anxiety and intention to undergo testing – will be measured with an online questionnaire, used by men in three of the study groups. Six months later, PSA test uptake will be ascertained from GP records; the online questionnaire will then be repeated. These outcomes, and particularly PSA test uptake, will be used to develop a mathematical simulation model, specifically to consider the impact on health service resources.

    Full Text Available Preventive vaccination is a highly promising strategy for interrupting leishmaniasis transmission that can, additionally, contribute to elimination. A vaccine formulation based on naturally excreted secreted (ES antigens was prepared from L. infantum promastigote culture supernatant. This vaccine achieved successful results in Phase III trials and was licensed and marketed as CaniLeish. We recently showed that newly identified ES promastigote surface antigen (PSA, from both viable promastigotes and axenically-grown amastigotes, represented the major constituent and the highly immunogenic antigen of L. infantum and L. amazonensis ES products. We report here that three immunizations with either the recombinant ES LaPSA-38S (rPSA or its carboxy terminal part LaPSA-12S (Cter-rPSA, combined with QA-21 as adjuvant, confer high levels of protection in naive L. infantum-infected Beagle dogs, as checked by bone marrow parasite absence in respectively 78.8% and 80% of vaccinated dogs at 6 months post-challenge. The parasite burden in infected vaccinated dogs was significantly reduced compared to placebo group, as measured by q-PCR. Moreover, our results reveal humoral and cellular immune response clear-cut differences between vaccinated and control dogs. An early increase in specific IgG2 antibodies was observed in rPSA/QA-21- and Cter-rPSA/QA-21-immunized dogs only. They were found functionally active in vitro and were highly correlated with vaccine protection. In vaccinated protected dogs, IFN-γ and NO productions, as well as anti-leishmanial macrophage activity, were increased. These data strongly suggest that ES PSA or its carboxy-terminal part, in recombinant forms, induce protection in a canine model of zoonotic visceral leishmaniasis by inducing a Th1-dominant immune response and an appropriate specific antibody response. These data suggest that they could be considered as important active components in vaccine candidates.

    Main objective of the project 3612R01550 performed on behalf of the Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety (BMUB) is the development of an approach for systematic consideration of dependencies in case of internal and external hazards and their combinations in the probabilistic plant model for nuclear power plants. One of the major aspects of a site specific Level 1 PSA carried out for a nuclear power plant outlined in this report is taking comprehensively into account the entire risks resulting from internal and external hazards. In a first step, all the hazards which may occur at the site under investigation have to be identified. This requires a compilation of the potential hazards and their possible combinations: Based on this compilation of generic hazards a site specific list of hazards to be considered in the analysis can be derived based on a screening process taking into account regulatory requirements and insights from site and plant walk-downs. In a second step, the hazards to be considered for the specific site have to be classified with respect to the depth of the probabilistic analyses to be carried out. This classification covers three categories: hazards with a negligible contribution to the overall risk, hazards with such a low risk contribution that a rough quantitative assessment is sufficient, and hazards which need in-depth probabilistic analysis. Based on the available Level 1 PSA model for internal events, a systematic approach for in-depth probabilistic analyses of hazards and their combinations is proposed. In this context, lists of those structures, systems and components, which can be impaired in their required function resulting in a risk increase, are provided. One of these lists contains the equipment, the other one the dependencies to be considered for the corresponding hazard. In addition to the general approach for performing site specific PSA, a procedure for modelling dependencies in

  18. Changes in prostate-specific antigen (PSA) level correlate with growth inhibition of prostate cancer cells treated in vitro with a novel anticancer drug, irofulven.

    Science.gov (United States)

    Woynarowska BAHigdon, A L; Muñoz, R M; Bushong, P; Waters, S J

    2001-01-01

    Irofulven (hydroxymethylacylfulvene, HMAF, MGI 114) is a novel agent with alkylating activity and a potent inducer of apoptosis. It is currently undergoing Phase II clinical trials for several tumor types, including hormone-refractory prostate cancer. Reduction of serum prostate-specific antigen (PSA) levels has been proposed as a generally useful endpoint for evaluating the antitumor efficacy of treatments for prostate cancer. However, the utility of PSA as a marker of tumor cell burden could be compromised, if drugs directly affected PSA secretion and/or expression. In these studies, we evaluated the effects of irofulven on PSA protein and mRNA levels during the course of treatment of prostate tumor cells in vitro. The rate of PSA secretion (normalized per equal cell number) by control and drug treated cells was similar, as determined by a solid phase, two-site immunoradiometric assay. Consistent with the lack of effect of irofulven on PSA protein level, the drug does not appear to affect the expression of PSA mRNA (on a per cell basis) as assessed by RT-PCR. Thus, changes in PSA secretion and expression appear to reflect irofulven-induced cell growth inhibition rather than reflecting a direct effect of the drug on PSA. These results suggest that PSA should be a reasonable marker of tumor burden in irofulven-treated prostate cancer patients.

  1. PSA testing for prostate cancer: an online survey of the views and reported practice of General Practitioners in the UK

    Directory of Open Access Journals (Sweden)

    Elwyn Glyn

    2005-06-01

    Full Text Available Abstract Background The role of Prostate Specific Antigen (PSA testing in the early detection of prostate cancer is controversial. Current UK policy stipulates that any man who wishes to have a PSA test should have access to the test, provided he has been given full information about the benefits and limitations of testing. This study aimed to determine UK GPs' current reported practice regarding PSA testing, and their views towards informed decision-making and PSA testing. Method Online questionnaire survey, with a sample of 421 GPs randomly selected from a database of GPs across the UK. Results 95% (400/421 of GPs responded. 76% of GPs reported having performed a PSA test for an asymptomatic man at least once in the previous three months, with 13% reported having tested more than five men in this period. A majority of GPs reported they would do a PSA test for men presenting with a family history and requesting a test, for asymptomatic men requesting a test and also for men presenting with lower urinary tract symptoms. Reported testing rates were highest for men with a family history. Amongst men with lower urinary tract symptoms and men with no symptoms, reported testing rates were significantly higher for older than younger men. The majority of GPs expressed support for the current policy (67%, and favoured both the general practitioner and the man being involved in the decision making process (83%. 90% of GPs indicated that they would discuss the benefits and limitation of testing with the man, with most (61% preferring to ask the man to make a further appointment if he decides to be tested. Conclusion This study indicates that PSA testing in asymptomatic men is a regular occurrence in the UK, and that there is general support from GPs for the current policy of making PSA tests available to 'informed' men who are concerned about prostate cancer. While most GPs indicated they would discuss the benefits and limitations prior to PSA testing

    Purpose: Prostate-specific antigen (PSA) bounce is a temporary elevation of the PSA level above a prior nadir. The purpose of this study was to determine whether the frequency of a PSA bounce following high-dose-rate (HDR) interstitial brachytherapy for the treatment of prostate cancer is associated with individual treatment fraction size. Methods and Materials: Between 1999 and 2014, 554 patients underwent treatment of low- or intermediate-risk prostate cancer with definitive HDR brachytherapy as monotherapy and had ≥3 subsequent PSA measurements. Four different fraction sizes were used: 950 cGy × 4 fractions, 1200 cGy × 2 fractions, 1350 cGy × 2 fractions, 1900 cGy × 1 fraction. Four definitions of PSA bounce were applied: ≥0.2, ≥0.5, ≥1.0, and ≥2.0 ng/mL above the prior nadir with a subsequent return to the nadir. Results: The median follow-up period was 3.7 years. The actuarial 3-year rate of PSA bounce for the entire cohort was 41.3%, 28.4%, 17.4%, and 6.8% for nadir +0.2, +0.5, +1.0, and +2.0 ng/mL, respectively. The 3-year rate of PSA bounce >0.2 ng/mL was 42.2%, 32.1%, 41.0%, and 59.1% for the 950-, 1200-, 1350-, and 1900-cGy/fraction levels, respectively (P=.002). The hazard ratio for bounce >0.2 ng/mL for patients receiving a single fraction of 1900 cGy compared with those receiving treatment in multiple fractions was 1.786 (P=.024). For patients treated with a single 1900-cGy fraction, the 1-, 2-, and 3-year rates of PSA bounce exceeding the Phoenix biochemical failure definition (nadir +2 ng/mL) were 4.5%, 18.7%, and 18.7%, respectively, higher than the rates for all other administered dose levels (P=.025). Conclusions: The incidence of PSA bounce increases with single-fraction HDR treatment. Knowledge of posttreatment PSA kinetics may aid in decision making regarding management of potential biochemical failures.

    The performance of prostate health index (phi) in predicting prostate biopsy outcomes has been well established for patients with prostate-specific antigen (PSA) values between 2 and 10 ng/mL. However, the performance of phi remains unknown in patients with PSA >10 ng/mL, the vast majority in Chinese biopsy patients. We aimed to assess the ability of phi to predict prostate cancer (PCa) and high-grade disease (Gleason Score ≥7) on biopsy in a Chinese population. This is a prospective, observational, multi-center study of consecutive patients who underwent a transrectal ultrasound guided prostate biopsy at four hospitals in Shanghai, China from August 2013 to December 2014. In the cohort of 1538 patients, the detection rate of PCa was 40.2%. phi had a significantly better predictive performance for PCa than total PSA (tPSA). The areas under the receiver operating characteristic curve (AUC) were 0.90 and 0.79 for phi and tPSA, respectively, P 10 ng/mL (N = 838, 54.5%). The detection rates of PCa were 35.9% and 57.7% in patients with tPSA 10.1-20 and 20.1-50 ng/mL, respectively. The AUCs of phi (0.79 and 0.89, for these two groups, respectively) were also significantly higher than tPSA (0.57 and 0.63, respectively), both P 10 ng/mL). © 2017 Wiley Periodicals, Inc.

    Full Text Available OBJETIVO: Estudar o perfil dos pacientes submetidos a biópsia prostática, determinando possíveis padrões que, associados aos níveis de PSA entre 2,6 e 10,0 ng/ml, possam levar a uma diminuição de biópsias desnecessárias. MATERIAIS E MÉTODOS: De 2007 a 2009, foi realizado um estudo transversal com 1.282 indivíduos submetidos a biópsia prostática e que apresentavam níveis de PSA entre 2,6 e 10,0 ng/ml. RESULTADOS: A prevalência de câncer foi de 28,6%. Pacientes com câncer eram, em média, mais idosos, com valores de PSA e densidade de PSA mais altos e menor volume da próstata. Na análise da densidade de PSA, os pacientes com câncer tiveram média de 0,31 ng/ml/cc, enquanto nos pacientes com resultado negativo a média foi de 0,10 ng/ml/cc. Utilizando como critério de positividade para câncer o ponto de corte de densidade de PSA de 0,15 ng/ml/cc, obtivemos especificidade de 74% e sensibilidade de 70%. Para aumentar a sensibilidade é preciso reduzir o ponto de corte. Com o valor 0,09 ng/ml/cc, obtivemos sensibilidade de 84% (IC 95%: 80-87% e especificidade de 75% (IC 95%: 72-78%. CONCLUSÃO: O uso sistemático da densidade de PSA na indicação de prosseguimento da investigação do paciente com biópsia poderia reduzir a quantidade de procedimentos desnecessários.

    2012-04-01

    We evaluated the relationship between bone metastasis (BM) and clinical or pathological variables, including the serum prostate-specific antigen (PSA) concentration. This retrospective study included 579 consecutive patients with newly diagnosed prostate cancer (Pca) who underwent a bone scan study at our institution between 2002 and 2010. We used receiver operating characteristics curves to evaluate accuracy of bone metastasis between serum PSA 10 and 20 ng/mL. A positive bone scan result was found in 83 men (14.3%) with PCa. However, 27 men (4.6%) with serum PSA between 10 and 20 ng/mL, 29/579 men (5.0%) with GS ≤ 7, and 21/83 (25.3%) with serum PSA ≤ 20 ng/mL and Gleason score (GS) ≤ 7 had positive bone scans. In the logistic regression analyses, clinical T stage (odds ratio [OR] = 3.26; 95% CI, 2.29-4.33; P = 0.021), GS (OR = 3.41; 95% CI, 2.91-4.63; P = 0.019), and serum PSA (OR = 8.37; 95% CI, 3.91-19.21; P bone scans for the detection of BM was 0.640 (P = 0.020; 95% CI, 0.563-0.717). With serum PSA at 10 ng/mL and GS ≤ 7, the AUC values of bone scans were 0.828 (P Bone scans might be necessary in men with serum PSA between 10 and 20 ng/mL. New guidelines for eliminating bone scans in patients with newly diagnosed Pca are needed, especially in Asians.

    Purpose Saw palmetto extracts are used for treating lower urinary tract symptoms in men despite level I evidence concluding that saw palmetto was ineffective in reducing lower urinary symptoms. We sought to determine whether higher doses of saw palmetto as studied in CAMUS affect serum PSA levels. Materials and Methods The CAMUS trial was a randomized, placebo-controlled double blind multi-centered North American trial conducted between June 5, 2008 and October 10, 2012 in which 369 men >45 years of age with AUA symptom score ≥ 8 and ≤ 24 were randomly assigned to placebo or dose escalation saw palmetto, which consisted of 320mg for first 24 weeks to 640mg for next 24 weeks to 960mg for last 24 weeks of this 72 week trial. Serum PSA levels (Beckman-Coulter) were obtained at baseline and at weeks 24, 48 and 72 and were compared between treatment groups using the pooled t and Fisher's exact tests. Results Serum PSA levels were similar at baseline for the placebo (1.93 ± 1.59 ng/ml) and saw palmetto groups (2.20 ± 1.95, p = 0.16). Changes in PSA levels over the course of the study were similar: placebo group mean change 0.16 ± 1.08 ng/ml and saw palmetto group mean change 0.23 ± 0.83 ng/ml (p value 0.50). Additionally, no differential effect on serum PSA levels was observed between treatment arms when groups were stratified by baseline PSA values. Conclusions Saw palmetto extract does not affect serum PSA levels more than placebo even at relatively high doses. PMID:23253958

  20. Exploring functional beta-cell heterogeneity in vivo using PSA-NCAM as a specific marker.

    Directory of Open Access Journals (Sweden)

    Melis Karaca

    Full Text Available BACKGROUND: The mass of pancreatic beta-cells varies according to increases in insulin demand. It is hypothesized that functionally heterogeneous beta-cell subpopulations take part in this process. Here we characterized two functionally distinct groups of beta-cells and investigated their physiological relevance in increased insulin demand conditions in rats. METHODS: Two rat beta-cell populations were sorted by FACS according to their PSA-NCAM surface expression, i.e. beta(high and beta(low-cells. Insulin release, Ca(2+ movements, ATP and cAMP contents in response to various secretagogues were analyzed. Gene expression profiles and exocytosis machinery were also investigated. In a second part, beta(high and beta(low-cell distribution and functionality were investigated in animal models with decreased or increased beta-cell function: the Zucker Diabetic Fatty rat and the 48 h glucose-infused rat. RESULTS: We show that beta-cells are heterogeneous for PSA-NCAM in rat pancreas. Unlike beta(low-cells, beta(high-cells express functional beta-cell markers and are highly responsive to various insulin secretagogues. Whereas beta(low-cells represent the main population in diabetic pancreas, an increase in beta(high-cells is associated with gain of function that follows sustained glucose overload. CONCLUSION: Our data show that a functional heterogeneity of beta-cells, assessed by PSA-NCAM surface expression, exists in vivo. These findings pinpoint new target populations involved in endocrine pancreas plasticity and in beta-cell defects in type 2 diabetes.

  1. Study on LOOP and SBO Frequency for Multi-Unit PSA

    In conventional single unit PSA, it was assumed that all accidents or events are independent and the risk of only one unit has been evaluated. In other words, the possibility that simultaneous events occur on multiple units was excluded because it was assumed that the probability of concurrent events were extremely low. After Fukushima accidents, however, it was found that external hazards such as tsunami may impact on multiple units; that means, for the sake of proper mitigation the risk of accidents in shared SSCs should be reevaluated. New risk metrics to improve conventional CDF (Core Damage frequency) based on reactor-year is needed to perform MUPSA (Multi-Unit Probabilistic Safety Assessment). IAEA suggested SCDF (Site CDF) as a risk metrics for MUPSA. The frequency based on reactor-year was converted to the frequency based on site-year. In addition, shared SSCs were modeled in single unit PSA as if those units have independent shared SSCs. Therefore, the risk of shared SSCs should be reevaluated. In this paper, the frequency of LOOP (Loss of Offsite Power), which is typically a multi-unit event, was evaluated and the frequency of SBO (Station Blackout) depending on LOOP frequency and emergency power systems such as EDG (Emergency Diesel Generator) and AAC (Alternate AC), that can mitigate SBO events, was modeled. This paper describes how to calculate LOOP and SBO frequency from the simple example for two-unit site with shared AAC. The events impacting on multiple units, which were excluded in conventional PSA, should be considered for MUPSA.

    Digital protection and control systems appear as upgrades in older plants, and are commonplace in new nuclear power plants. To assess the risk of nuclear power plant operation and to determine the risk impact of digital systems, there is a need to quantitatively assess the reliability of the digital systems in a justifiable manner. In 2007, the OECD/NEA CSNI directed the Working Group on Risk Assessment (WGRisk) to set up a task group to coordinate an activity in this field. One of the recommendations was to develop a taxonomy of failure modes of digital components for the purposes of probabilistic safety assessment (PSA), resulting in a follow-up task group called DIGREL. The taxonomy will be the basis of future modelling and quantification efforts. It will also help define a structure for data collection and to review PSA studies. This an interim report of the project. A draft guidelines document on the failure modes taxonomy has been developed. The taxonomy is rather complete covering all levels from the system level down to module and basic component level failure modes, including hardware and software aspects. There are still open issues to be resolved by the task group, especially related to I and C unit and module level taxonomy. In a parallel Nordic activity, a comparison of Nordic experiences and a literature review on main international references has been performed. The study showed a wide range of approaches and solutions to the challenges given by digital I and C, and also indicated that no state-of-the-art currently exists. An existing simplified PSA model has been complemented with fault tree models for a four-redundant distributed protection system in order to study and demonstrate the effect of design features and modelling approaches. The model has been used to test the effect of CCF modelling, fail-safe principle and voting logic. A comparison has been made between unit-level and module-level modelling. (Author)

    The PSA's Solar Furnace capabilities can be greatly improved by replacing the present array mirrors with new ones. We will explain a rather cheap method (now under test) for the fabrication of the new mirrors, with a simple spherical figuring, and everyone identical to each other. Furthermore, we will describe the geometry the new array should have in order to avoid excessive aberrations due to the high obliquity of the rays with which most of the mirrors in the array have to deal with.

    We researched the usefulness of optimizing prostate cancer (PC) screening in our community using baseline PSA readings in men between 40-49 years of age. A retrospective study was performed that analyzed baseline PSA in the fifth decade of life and its ability to predict the development of PC in a population of Madrid (Spain). An ROC curve was created and a cutoff was proposed. We compared the evolution of PSA from baseline in patients with consecutive readings using the Friedman test. We established baseline PSA ranges with different risks of developing cancer and assessed the diagnostic utility of the annual PSA velocity (PSAV) in this population. Some 4,304 men aged 40-49 years underwent opportunistic screening over the course of 17 years, with at least one serum PSA reading (6,001 readings) and a mean follow-up of 57.1±36.8 months. Of these, 768 underwent biopsy of some organ, and 104 underwent prostate biopsy. Fourteen patients (.33%) were diagnosed with prostate cancer. The median baseline PSA was .74 (.01-58.5) ng/mL for patients without PC and 4.21 (.76-47.4) ng/mL for those with PC. The median time from the reading to diagnosis was 26.8 (1.5-143.8) months. The optimal cutoff for detecting PC was 1.9ng/mL (sensitivity, 92.86%; specificity, 92.54%; PPV, 3.9%; NPV, 99.97%), and the area under the curve was 92.8%. In terms of the repeated reading, the evolution of the PSA showed no statistically significant differences between the patients without cancer (p=.56) and those with cancer (P=.64). However, a PSAV value >.3ng/mL/year revealed high specificity for detecting cancer in this population. A baseline PSA level ≥1.9ng/mL in Spanish men aged 40-49 years predicted the development of PC. This value could therefore be of use for opportunistic screening at an early age. An appropriate follow-up adapted to the risk of this population needs to be defined, but an annual PSAV ≥.3ng/mL/year appears of use for reaching an early diagnosis. Copyright © 2015 AEU

    We examined the usefulness of prostate specific antigen density (PSAD) for selection of biopsy candidate with prostate specific antigen levels between 4.1 and 10.0 ng./ml. in prostate cancer screening retrospectively. The screening was conducted on male candidates in Natori city, aged 55 years or older, for 6 years from 1994 through 1999. We could analyze serum PSA levels and PSA density in 118 men with PSA levels between 4.1 and 10.0 ng./ml. All of 118 men underwent ultrasound guided systematic prostate biopsy regardless of findings of digital rectal examination and transrectal ultrasound. Prostate volume was estimated by transrectal ultrasound measurements using the prolate ellipse formula (pi/6 x length x width x height). PSAD was calculated by dividing serum PSA level by prostate volume. Serum PSA levels were determined by Tandem-R assay. In 118 men, twenty-five men had prostate cancer. There was no significant difference in mean PSA between those with prostate cancer and those without prostate cancer, but the difference was significant in the mean PSA density (mean 0.26 and 0.16, respectively, p PSA and PSAD demonstrated superior benefit for PSAD in 118 men. A sensitivity, a specificity, a positive predictive value and a negative predictive value of PSAD cut-off of 0.15 were 88%, 52.7%, 33.3% and 94.2%. PSAD cut-off of 0.18 showed the highest sum of sensitivity and specificity, which gave a sensitivity of 80%, a specificity of 72%, a positive predictive value of 43.5% and a negative predictive value of 93.1%. PSAD cut-off of 0.15 would seem to be preferable to cut-off of 0.18 because of less cancer missing. Although further studies are needed to determine optimal cut-off value to be used in clinical practice, PASD seems to be useful for the selection of biopsy candidates with PSA levels of 4.1 to 10.0 ng./ml. in the prostate cancer screening.

    Full Text Available Abstract Background To validate an artificial neural network (ANN based on the combination of PSA velocity (PSAV with a %free PSA-based ANN to enhance the discrimination between prostate cancer (PCa and benign prostate hyperplasia (BPH. Methods The study comprised 199 patients with PCa (n = 49 or BPH (n = 150 with at least three PSA estimations and a minimum of three months intervals between the measurements. Patients were classified into three categories according to PSAV and ANN velocity (ANNV calculated with the %free based ANN "ProstataClass". Group 1 includes the increasing PSA and ANN values, Group 2 the stable values, and Group 3 the decreasing values. Results 71% of PCa patients typically have an increasing PSAV. In comparison, the ANNV only shows this in 45% of all PCa patients. However, BPH patients benefit from ANNV since the stable values are significantly more (83% vs. 65% and increasing values are less frequently (11% vs. 21% if the ANNV is used instead of the PSAV. Conclusion PSAV has only limited usefulness for the detection of PCa with only 71% increasing PSA values, while 29% of all PCa do not have the typical PSAV. The ANNV cannot improve the PCa detection rate but may save 11–17% of unnecessary prostate biopsies in known BPH patients.

    Full Text Available Transrectal ultrasound (TRUS–guided prostate biopsy is known to carry a significant false-negative rate, leading some patients to have multiple biopsies. We investigated cancer detection rates in patients with a PSA >20 ng/ml and a negative initial biopsy. We reviewed our database of 2396 TRUS-guided biopsies done between 1997 and 2002 in order to give a follow-up of at least 6 years. PSA, PSA density (PSAD, PSA velocity (PSAV, prostate volume, and DRE findings were analysed in relation to cancer status. Of the patients, 388 (16% had a PSA >20 ng/ml, including 99 (26% with benign biopsies. Of those, 67 were rebiopsied, including 19 (28% with cancer on the first rebiopsy and four (6% on further biopsies. PSAD, DRE, and volume significantly differed between rebiopsied patients with and without cancer (p 20 ng/ml and have an initial negative biopsy have a high chance of malignancy being detected on a second biopsy. However, if a second biopsy is also negative, then the chances of subsequent biopsies showing signs of cancer are very low if the DRE is normal and particularly if the PSAD is >0.35 ng/ml/cm3.

    This paper describes the development process, the innovative techniques used and insights gained from the latest integrated, full scope, multistate Level 2 PSA analysis conducted at the Leibstadt Nuclear Power Plant (KKL), Switzerland. KKL is a modern single-unit General Electric Boiling Water Reactor (BWR/6) with Mark III Containment, and a power output of 3600MWth/1200MWe, the highest among the five operating reactors in Switzerland. A Level 2 Probabilistic Safety Assessment (PSA) analyses accident phenomena in nuclear power plants, identifies ways in which radioactive releases from plants can occur and estimates release pathways, magnitude and frequency. This paper attempts to give an overview of the advanced modeling techniques that have been developed and implemented for the recent KKL Level 2 PSA update, with the aim of systematizing the analysis and modeling processes, as well as complying with the relatively prescriptive Swiss requirements for PSA. The analysis provides significant insights into the absolute and relative importance of risk contributors and accident prevention and mitigation measures. Thanks to several newly developed techniques and an integrated approach, the KKL Level 2 PSA report exhibits a high degree of reviewability and maintainability, and transparently highlights the most important risk contributors to Large Early Release Frequency (LERF) with respect to initiating events, components, operator actions or seismic component failure probabilities (fragilities)

    Study about the efficacy of salvage radiotherapy (RT), in terms of biochemical disease free survival (bDFS), according to ASTRO and Phoenix (nadir+2) definitions, for persistent or rising PSA after radical prostatectomy. Retrospective analysis of 59 patients who underwent RT between 1990 and 2003 for PSA recurrence after radical prostatectomy. Patients received a median of 66Gy to the prostate bed with 3D or 2D RT. The main end point was bDFS according to ASTRO and Phoenix (nadir+2) definitions. Different criterion sets were analysed to calculate bDFS and pretreatment factors that might predict biochemical relapse were sought for each. After a 38-month median follow-up, the 3-year bDFS rates were: 60 and 72% for ASTRO and Phoenix (nadir+2 ng/ml) definitions respectively. According to univariate analysis, pre-RT PSA> or =1 ng/ml and seminal vesicle involvement were associated with biochemical relapse. Multivariate analysis retained only pre-RT PSA> or =1 ng/ml as an independent predictor of biochemical relapse for the two definitions. Salvage RT is an effective treatment after radical prostatectomy according to ASTRO or Phoenix definitions. Only pre-RT PSA> or =1 ng/ml predicted relapse.

    Full Text Available Einleitung: Die diagnostische Biopsie der Prostata führt bekanntermaßen zum Anstieg des Serum-PSA-Spiegels. Diese prospektive Untersuchung sollte die Frage klären, ob die Änderungen des Serum-PSA-Spiegels nach Stanzbiopsie Rückschlüsse auf das histologische Ergebnis zulassen und so als Entscheidungshilfe bei der Frage der Rebiopsie dienen können. Patienten und Methoden: Insgesamt 79 konsekutive Patienten mit klinischem Verdacht auf das Vorliegen eines Prostatakarzinoms (PCA und einem Gesamt-PSA 50 ng/ml wurden in die Studie eingeschlossen. Ausschlußkriterien waren klinische Hinweise für eine Prostatitis und Prostatabiopsie innerhalb der letzten 3 Monate. Die Serum-PSA-Werte wurden mit einem ultrasensitiven Enzymimmunoassay bestimmt. Die Bestimmung des Gesamt-PSA und des freien PSA im Serum erfolgte unmittelbar vor und 60 Minuten nach der Biopsie. Die Spiegel des Gesamt-PSA und freien PSA, sowie die f/t-PSA-Ratio vor und nach Biopsie wurden in Korrelation zum histologischen Ergebnis gesetzt. Ergebnisse: 86 Biopsieserien wurden bei 79 Patienten durchgeführt. 38 Biopsieserien diagnostizierten ein PCA, 48 eine benigne Prostatahyperplasie (BPH. Die abschließende Histologie nach wiederholter Biopsie war PCA und BPH in je 43 Fällen. Insgesamt fand sich ein Anstieg des durchschnittlichen Gesamt-PSA von 18,39 ng/ml auf 107,8 ng/ml, des durchschnittlichen freien PSA von 3,43 ng/ml auf 33,7 ng/ml und der durchschnittlichen f/t PSA-Ratio von 18,1 % auf 52,0 %. Es fand sich keine Korrelation zwischen dem Anstieg dieser Parameter und der Anzahl der Biopsiezylinder (4–51. Bezüglich des histologischen Befundes ergaben sich statistisch signifikante Unterschiede für das Gesamt-PSA vor und die f/t PSA-Ratio vor und nach Stanzbiopsie. Schlußfolgerung: Die Analyse der PSA-Parameter nach Stanzbiopsie bietet keine zusätzliche Information über die konventionellen PSA-Parameter vor der Biopsie hinaus.

    We sought to determine predictors for early and late biochemical recurrence following radical prostatectomy among localized prostate cancer patients. The study included localized prostate cancer patients treated with radical prostatectomy (RP) at the University of Southern California from 1988 to 2008. Competing risks regression models were used to determine risk factors associated with earlier or late biochemical recurrence, defined using the median time to biochemical recurrence in this population (2.9 years after radical prostatectomy). The cohort for this study included 2262 localized prostate cancer (pT2-3N0M0) patients who did not receive neoadjuvant or adjuvant therapies. Of these patients, 188 experienced biochemical recurrence and a subset continued to clinical recurrence, either within (n=19, 10%) or following (n=13, 7%) 2.9 years after RP. Multivariable stepwise competing risks analysis showed Gleason score ≥7, positive surgical margin status, and ≥pT3a stage to be associated with biochemical recurrence within 2.9 years following surgery. Predictors of biochemical recurrence after 2.9 years were Gleason score 7 (4+3), preoperative prostate-specific antigen (PSA) level, and ≥pT3a stage. Higher stage was associated with biochemical recurrence at any time following radical prostatectomy. Particular attention may need to be made to patients with stage ≥pT3a, higher preoperative PSA, and Gleason 7 prostate cancer with primary high-grade patterns when considering longer followup after RP.

    Many centres currently do not offer radical prostatectomy (RP) to men with high-risk localised prostate cancer due to concerns regarding poor outcome, despite evidence to the contrary. We identified 18 men undergoing RP with serum PSA >20 ng\\/ml (high-risk by National Comprehensive Cancer Network definition) and minimum follow-up of 12 years (mean 13.5). Mean preoperative PSA was 37.0 ng\\/ml (Range 21.1-94.0). Prostatectomy pathology reported extracapsular disease in 16 (88.9%), positive surgical margins in 15 (83%) and positive pelvic lymph nodes in 5 (27.8%). Overall and cancer-specific survival at 5 and 10-years was 83.3%, 88.2%, 72% and 76.5% respectively. With complete follow-up 11 (61.1%) are alive, and 5 (27.8%) avoided any adjuvant therapy. Complete continence (defined as no involuntary urine leakage and no use of pads) was achieved in 60%, with partial continence in the remainder. We conclude that surgery for this aggressive variant of localised prostate cancer can result in satisfactory outcome.

  2. MODIFICATION OF THE SPAR-H METHOD TO SUPPORT HRA FOR LEVEL 2 PSA

    Currently, available Human Reliability Analysis (HRA) methods were generally developed to support Level 1 Probabilistic Safety Analysis (PSA) models. There has been an increased emphasis placed on Level 2 PSA in recent years; however, the currently used HRA methods are not ideal for this application, including the SPAR-H method. Challenges that will likely be present during a severe accident such as degraded or hazardous operating conditions, shift in control from the main control room to the technical support center, unavailability of instrumentation, and others are not routinely considered for Level 1 HRA analysis. These factors combine to create a much more uncertain condition to be accounted for in the HRA analysis. While the SPAR-H shaping factors were established to support Level 1 HRA, previous studies have shown it may be used for Level 2 HRA analysis as well. The Canadian Nuclear Safety Commission (CNSC) and Idaho National Laboratory (INL) in a joint project are investigating modifications to the SPAR-H method to create more consistency in applying the performance shaping factors used in the method for Level 2 analysis.

These results will give a physical insight in the development of a new dispersion model. A wind tunnel experiment with bell shaped hill model was made in order to develop a new dispersion model. And an improved dispersion model was developed based on the concentration distribution data obtained from the wind tunnel experiment. This model will be added as an option to the atmospheric dispersion code. A stand-alone atmospheric code using MS Visual Basic programming language which runs at the Windows environment of a PC was developed. A user can easily select a necessary data file and type input data by clicking menus, and can select calculation options such building wake, plume rise etc., if necessary. And a user can easily understand the meaning of concentration distribution on the map around the plant site as well as output files. Also the methodologies for the estimation of radiation exposure and for the calculation of risks was established. These methodologies will be used for the development of modules for the radiation exposure and risks respectively. These modules will be developed independently and finally will be combined to the atmospheric dispersion code in order to develop a level 3 PSA code. 30 tabs., 56 figs., refs. (Author).

    The variety of accident sequences to be considered in the framework of a PSA derives from mutual dependencies between the physical process, the behaviour of the technical system, human actions and stochastic influences along the time axis. Because the conventional PSA approach is not able to adequately account for these interactions, so-called probabilistic dynamics methods have been developed. They generally achieve a more realistic modelling of accident scenarios and a more realistic safety assessment. At GRS, the method MCDET - a combination of Monte Carlo Simulation und the Discrete Dynamic Event Tree method - was developed. The implementation of MCDET was supplemented by a so called Crew-Module which allows - together with a deterministic dynamics code - to simulate human actions as a dynamic process evolving over time in interaction with the system and process dynamics. The Crew-Module accounts for communications between crew members and for performance shaping factors like stress, knowledge or ergonomics. This paper presents the Crew- Module and gives an overview of the results which may be obtained from its combination with MCDET and a deterministic dynamics code. The emergency operating procedure 'Secondary Side Bleed and Feed' in a German PWR is selected as an illustrative application. (authors)

    In the course of the research and development project RS1539 funded by the German Federal Ministry for Economics and Energy (BMWi) the methodology for the automated integration of hazards in Level 1 PSA models has been enhanced. Thereby, the analysis tool pyRiskRobot provides the methodological framework for mapping a generic spectrum of internal and external hazards onto complex PSA plant models. The reimplementation of the software tool via the programming language python extends the applicability and facilitates the handling of pyRiskRobot in comparison to the previous Ruby-based version RiskRobot. Moreover, the development of functions to perform the topological modelling of fault trees and the probabilistic specification of modified fault tree elements have been continued. Due to the reimplementation and further developments, the tool enables to systematically generate fault trees of varying complexity, to flexibly integrate fault trees in existing PSA models and to automatically duplicate interconnected topologies. Thus, pyRiskRobot allows the efficient and traceable realization of hazard specific, usually laborious modifications of PSA models. In addition, pyRiskRobot has been extended to serve as a functional interface between the data compilations comprising the potential influences of hazards on PSA relevant components and the data base of a PSA plant model. Based on this conceptual design, additional analyses of the data can be carried out prior to the integration within the PSA model topology. The reimplemented functionalities of pyRiskRobot have been validated with respect to reference applications, such as the modelling of an internal fire scenario, against the previous version RiskRobot. The existing method collection for the automated modification of fault tree topologies has been extended based on the requirements for further applications, among others the modelling of an external flooding scenario. The deduced hazard specific modelling approaches

    Full Text Available Alpha linolenic acid (ALA is the major omega-3 fatty acid in the diet. Evidence on health effects of ALA is not conclusive, but some observational studies found an increased risk of prostate cancer with higher intake of ALA. We examined the effect of ALA supplementation on serum concentrations of prostate-specific antigen (PSA, a biomarker for prostate cancer.The Alpha Omega Trial (ClinicalTrials.gov Identifier: NCT00127452 was a double-blind, placebo-controlled trial of ALA and the fish fatty acids eicosapentanoic acid (EPA and docosahexanoic acid (DHA on the recurrence of cardiovascular disease, using a 2×2 factorial design. Blood was collected at the start and the end of the intervention period. The present analysis included 1622 patients with a history of a myocardial infarction, aged 60-80 years with an initial PSA concentration 4 ng/mL.Mean serum PSA increased by 0.42 ng/mL on placebo (n = 815 and by 0.52 ng/mL on ALA (n = 807, a difference of 0.10 (95% confidence interval: -0.02 to 0.22 ng/mL (P = 0·12. The odds ratio for PSA rising above 4 ng/mL on ALA versus placebo was 1.15 (95% CI: 0.84-1.58.An additional amount of 2 g of ALA per day increased PSA by 0.10 ng/mL, but the confidence interval ranged from -0.02 to 0.22 ng/mL and included no effect. Therefore, more studies are needed to establish whether or not ALA intake has a clinically significant effect on PSA or prostate cancer.ClinicalTrials.gov; Identifier: NCT00127452.

  3. The contribution of the Patient Support Assistant to direct patient care: an exploration of nursing and PSA role perceptions.

    2007-04-01

    Health care systems have seen the introduction of the unregulated worker into patient care areas to assist Registered Nurses (RNs) in the provision of health care. A study was undertaken to identify the perceptions of both nurses and unregulated workers of the unregulated worker role in direct patient care in a regional hospital in New South Wales, Australia. The nomenclature used for a non regulated worker in the workplace in which this study occurred is Patient Support Assistant (PSA). Separate surveys were designed for PSA and nursing staff. Twenty seven per cent of PSAs (n=21) and 36% of nursing staff surveyed (n=120) responded. Results identified that both groups identified the main role of PSAs were attending to general cleaning and providing physical assistance to nurses, medical and physiotherapy staff, primarily for manual handling of heavy or difficult patients. Some activities of the role identified in the job description, such as pre-operative shaves on male patients and assisting with the application of traction, appeared no longer to be relevant for current practices. Both groups identified a positive team working relationship between nurses and PSAs. However, there was evidence to suggest that not all RNs had a clear understanding of the role of the PSA and the PSAs believed that they did not receive adequate feedback about their work. There was a mixed view as to whom the PSA should report. A high percentage of RNs felt they should be responsible for the supervision of the PSA. This was in contrast to a high percentage also believing that RNs should not be accountable either for PSA work or for delegating tasks to PSAs. Challenges voiced by PSAs included being expected to achieve both allocated cleaning tasks and provide patient support, being requested to assist with aggressive patients and working with other PSAs. A major recommendation of the study is that employment of Assistants in Nursing may provide enhanced scope and role clarity for

  4. Phytohormone and Putative Defense Gene Expression Differentiates the Response of ‘Hayward’ Kiwifruit to Psa and Pfm Infections

    2017-08-01

    Full Text Available Pseudomonas syringae pv. actinidiae (Psa and Pseudomonas syringae pv. actinidifoliorum (Pfm are closely related pathovars infecting kiwifruit, but Psa is considered one of the most important global pathogens, whereas Pfm is not. In this study of Actinidia deliciosa ‘Hayward’ responses to the two pathovars, the objective was to test whether differences in plant defense responses mounted against the two pathovars correlated with the contrasting severity of the symptoms caused by them. Results showed that Psa infections were always more severe than Pfm infections, and were associated with highly localized, differential expression of phytohormones and putative defense gene transcripts in stem tissue closest to the inoculation site. Phytohormone concentrations of jasmonic acid (JA, jasmonate isoleucine (JA-Ile, salicylic acid (SA and abscisic acid were always greater in stem tissue than in leaves, and leaf phytohormones were not affected by pathogen inoculation. Pfm inoculation induced a threefold increase in SA in stems relative to Psa inoculation, and a smaller 1.6-fold induction of JA. Transcript expression showed no effect of inoculation in leaves, but Pfm inoculation resulted in the greatest elevation of the SA marker genes, PR1 and glucan endo-1,3-beta-glucosidase (β-1,3-glucosidase (32- and 25-fold increases, respectively in stem tissue surrounding the inoculation site. Pfm inoculation also produced a stronger response than Psa inoculation in localized stem tissue for the SA marker gene PR6, jasmonoyl-isoleucine-12-hydrolase (JIH1, which acts as a negative marker of the JA pathway, and APETALA2/Ethylene response factor 2 transcription factor (AP2 ERF2, which is involved in JA/SA crosstalk. WRKY40 transcription factor (a SA marker was induced equally in stems by wounding (mock inoculation and pathovar inoculation. Taken together, these results suggest that the host appears to mount a stronger, localized, SA-based defense response to Pfm

  6. Permanent 125I-seed prostate brachytherapy: early prostate specific antigen value as a predictor of PSA bounce occurrence

    Directory of Open Access Journals (Sweden)

    Mazeron Renaud

    2012-03-01

    Full Text Available Abstract Purpose To evaluate predictive factors for PSA bounce after 125I permanent seed prostate brachytherapy and identify criteria that distinguish between benign bounces and biochemical relapses. Materials and methods Men treated with exclusive permanent 125I seed brachytherapy from November 1999, with at least a 36 months follow-up were included. Bounce was defined as an increase ≥ 0.2 ng/ml above the nadir, followed by a spontaneous return to the nadir. Biochemical failure (BF was defined using the criteria of the Phoenix conference: nadir +2 ng/ml. Results 198 men were included. After a median follow-up of 63.9 months, 21 patients experienced a BF, and 35.9% had at least one bounce which occurred after a median period of 17 months after implantation (4-50. Bounce amplitude was 0.6 ng/ml (0.2-5.1, and duration was 13.6 months (4.0-44.9. In 12.5%, bounce magnitude exceeded the threshold defining BF. Age at the time of treatment and high PSA level assessed at 6 weeks were significantly correlated with bounce but not with BF. Bounce patients had a higher BF free survival than the others (100% versus 92%, p = 0,007. In case of PSA increase, PSA doubling time and velocity were not significantly different between bounce and BF patients. Bounces occurred significantly earlier than relapses and than nadir + 0.2 ng/ml in BF patients (17 vs 27.8 months, p Conclusion High PSA value assessed 6 weeks after brachytherapy and young age were significantly associated to a higher risk of bounces but not to BF. Long delays between brachytherapy and PSA increase are more indicative of BF.

    Full Text Available Objectives: Stereotactic body radiation therapy (SBRT takes advantage of the prostate’s low α/β ratio to deliver a large radiation dose in few fractions. Initial studies on small groups of low-risk patients support SBRT’s potential for clinical efficacy while limiting treatment-related morbidity and maintained quality of life (QOL. This prospective study expands upon prior studies to further evaluate SBRT efficacy for a large patient population with organ confined, low- and intermediate-risk prostate cancer patients. Methods: 477 patients with prostate cancer received CyberKnife SBRT. The median age was 68.6 years and the median PSA was 5.3 ng/ml. 324 patients were low-risk (PSA 10, or Gleason 3+4 with PSA <10; n=106 had a significantly higher bDFS than patients with high intermediate-risk (Gleason 3+4 with PSA 10-20 or Gleason 4+3; n=47, with bDFS of 93.5% versus 79.3%, respectively. For the low and low intermediate-risk groups, there was no difference in median PSA nadir or biochemical disease control between doses of 35 and 36.25 Gy. Conclusions: CyberKnife SBRT produces excellent biochemical control rates. Median PSA levels compare f

    2015-01-01

    Full Text Available Objective. To evaluate the diagnostic impact of 11C–Choline PET / CT in the detection of recurrent prostate cancer (PCa in patients with biochemical relapse after radical prostatectomy and to assess the correlation between PSA levels and PET / CT detection rate of PCa relapse.Subjects and methods. 85 patients with biochemical relapse (mean PSA 3.51 ± 3.87 ng / ml after radical prostatectomy (n = 64 and radiotherapy (n = 21 underwent 11C–Choline PET / CT. According to PSA level, patients were divided into three groups:  2 ng / ml, 2 to 9 ng / ml and > 9 ng / ml.Results. Overall, 11C–Choline PET / CT detected PCa relapse in 33 of 85 patients (39 %. The mean PSA value in PET-positive patients was 5.78 ± 4.95 (0.22–17.80 ng / ml, while in PET-negative patients – 1.43 ± 1.08 (0.28–4.57 ng / ml. Positive PET / CT results were obtained in 9 of 40 patients (22 % with PSA of < 2 ng / ml, in 17 of 38 patients (45 % with PSA of 2 to 9 ng / ml, and in 7 of 7 patients (100 % with PSA of > 9 ng / ml. Local relapse was detected in 42 % (14 / 33 patients. Both local and distant metastases were diagnosed in 39 % (13 / 33 cases. Distant relapsewas identified in 19 % (6 / 33 cases. PET / CT allowed to assess the efficacy of treatment in 26 % (12 / 47 PET-negative patients under hormone therapy at the scan time. However, PET / CT wasn’t able to localize the site of PCa recurrence in these hormone-ensitive patients what might have affected the overall detection rate.Conclusion. 1 11C–Choline PET / CT was able to detect and correctly identify the site of PCa relapse in 39 % cases and therefore was useful in determining the further therapeutic approach. 2 Our data confirmed the strong correlation between PSA levels and 11C–Choline PET / CT detection rate of PCa relapse (r = 0.9; p < 0.001. 3 11C–Choline PET / CT has limited utility in localizing the site of PCa recurrence in some patients under hormone therapy.

  2. The California Earthquake Advisory Plan: A history

    Science.gov (United States)

    Roeloffs, Evelyn A.; Goltz, James D.

    2017-01-01

    Since 1985, the California Office of Emergency Services (Cal OES) has issued advisory statements to local jurisdictions and the public following seismic activity that scientists on the California Earthquake Prediction Evaluation Council view as indicating elevated probability of a larger earthquake in the same area during the next several days. These advisory statements are motivated by statistical studies showing that about 5% of moderate earthquakes in California are followed by larger events within a 10-km, five-day space-time window (Jones, 1985; Agnew and Jones, 1991; Reasenberg and Jones, 1994). Cal OES issued four earthquake advisories from 1985 to 1989. In October, 1990, the California Earthquake Advisory Plan formalized this practice, and six Cal OES Advisories have been issued since then. This article describes that protocol’s scientific basis and evolution.

    Conclusion: The %fPSA is an effective discriminating tool in determining the need for prostate biopsy in indigenous West African men with PSA 4–10 ng/ml. A cut off of 15% was associated with the highest performance.

  4. Advanced Reactor PSA Methodologies for System Reliability Analysis and Source Term Assessment

    Energy Technology Data Exchange (ETDEWEB)

    Grabaskas, D.; Brunett, A.; Passerini, S.; Grelle, A.; Bucknor, M.

    2017-06-26

    Beginning in 2015, a project was initiated to update and modernize the probabilistic safety assessment (PSA) of the GE-Hitachi PRISM sodium fast reactor. This project is a collaboration between GE-Hitachi and Argonne National Laboratory (Argonne), and funded in part by the U.S. Department of Energy. Specifically, the role of Argonne is to assess the reliability of passive safety systems, complete a mechanistic source term calculation, and provide component reliability estimates. The assessment of passive system reliability focused on the performance of the Reactor Vessel Auxiliary Cooling System (RVACS) and the inherent reactivity feedback mechanisms of the metal fuel core. The mechanistic source term assessment attempted to provide a sequence specific source term evaluation to quantify offsite consequences. Lastly, the reliability assessment focused on components specific to the sodium fast reactor, including electromagnetic pumps, intermediate heat exchangers, the steam generator, and sodium valves and piping.

  6. Guidelines for reliability analysis of digital systems in PSA context. Phase 1 status report

    Digital protection and control systems are appearing as upgrades in older nuclear power plants (NPPs) and are commonplace in new NPPs. To assess the risk of NPP operation and to determine the risk impact of digital system upgrades on NPPs, quantitative reliability models are needed for digital systems. Due to the many unique attributes of these systems, challenges exist in systems analysis, modeling and in data collection. Currently there is no consensus on reliability analysis approaches. Traditional methods have clearly limitations, but more dynamic approaches are still in trial stage and can be difficult to apply in full scale probabilistic safety assessments (PSA). The number of PSAs worldwide including reliability models of digital I and C systems are few. A comparison of Nordic experiences and a literature review on main international references have been performed in this pre-study project. The study shows a wide range of approaches, and also indicates that no state-of-the-art currently exists. The study shows areas where the different PSAs agree and gives the basis for development of a common taxonomy for reliability analysis of digital systems. It is still an open matter whether software reliability needs to be explicitly modelled in the PSA. The most important issue concerning software reliability is proper descriptions of the impact that software-based systems has on the dependence between the safety functions and the structure of accident sequences. In general the conventional fault tree approach seems to be sufficient for modelling reactor protection system kind of functions. The following focus areas have been identified for further activities: 1. Common taxonomy of hardware and software failure modes of digital components for common use 2. Guidelines regarding level of detail in system analysis and screening of components, failure modes and dependencies 3. Approach for modelling of CCF between components (including software). (Author)

    Prostate-specific antigen (PSA) is a widely used specific tumor marker for prostate cancer. We experienced a case of metastatic prostate cancer that was difficult to detect by repeat prostate biopsy despite a markedly elevated serum PSA level. A 64-year-old man was referred to our hospital with lumbar back pain and an elevated serum PSA level of 2036 ng/mL. Computed tomography, bone scintigraphy, and magnetic resonance imaging showed systemic lymph node and osteoblastic bone metastases. Digital rectal examination revealed a small, soft prostate without nodules. Ten-core transrectal prostate biopsy yielded negative results. Androgen deprivation therapy (ADT) was started because of the patient's severe symptoms. Twelve-core repeat transrectal prostate biopsy performed 2 months later, and transurethral resection biopsy performed 5 months later, both yielded negative results. The patient refused further cancer screening because ADT effectively relieved his symptoms. His PSA level initially decreased to 4.8 ng/mL, but he developed castration-resistant prostate cancer 7 months after starting ADT. He died 21 months after the initial prostate biopsy from disseminated intravascular coagulation. CUP remains a considerable challenge in clinical oncology. Biopsies of metastatic lesions and multimodal approaches were helpful in this case.

  10. A Human Reliability Analysis of Post- Accident Human Errors in the Low Power and Shutdown PSA of KSNP

    Korea Atomic Energy Research Institute, using the ANS low power and shutdown (LPSD) probabilistic risk assessment (PRA) Standard, evaluated the LPSD PSA model of the KSNP, Yonggwang Units 5 and 6, and identified the items to be improved. The evaluation results of human reliability analysis (HRA) of the post-accident human errors in the LPSD PSA model for the KSNP showed that 10 items among 19 items of supporting requirements for those in the ANS PRA Standard were identified as them to be improved. Thus, we newly carried out a HRA for post-accident human errors in the LPSD PSA model for the KSNP. Following tasks are the improvements in the HRA of post-accident human errors of the LPSD PSA model for the KSNP compared with the previous one: Interviews with operators in the interpretation of the procedure, modeling of operator actions, and the quantification results of human errors, site visit. Applications of limiting value to the combined post-accident human errors. Documentation of information of all the input and bases for the detailed quantifications and the dependency analysis using the quantification sheets The assessment results for the new HRA results of post-accident human errors using the ANS LPSD PRA Standard show that above 80% items of its supporting requirements for post-accident human errors were graded as its Category II. The number of the re-estimated human errors using the LPSD Korea Standard HRA method is 385. Among them, the number of individual post-accident human errors is 253. The number of dependent post-accident human errors is 135. The quantification results of the LPSD PSA model for the KSNP with new HEPs show that core damage frequency (CDF) is increased by 5.1% compared with the previous baseline CDF It is expected that this study results will be greatly helpful to improve the PSA quality for the domestic nuclear power plants because they have sufficient PSA quality to meet the Category II of Supporting Requirements for the post

    Korea Atomic Energy Research Institute, using the ANS Low Power /Shutdown (LPSD)PRA Standard, evaluated the LPSD PSA model of the KSNP, Younggwang (YGN) Units 5 and 6, and identified the items to be improved. The evaluation results of human reliability analysis (HRA) of the pre-accident human errors in the LPSD PSA model of the KSNP showed that 13 items among 15 items of supporting requirements for those in the ANS PRA Standard were identified as them to be improved. Thus, we newly carried out a HRA for pre-accident human errors in the LPSD PSA model for the KSNP to improve its quality. We considered potential pre-accident human errors for all manual valves and control/instrumentation equipment of the systems modeled in the KSNP LPSD PSA model except reactor protection system/ engineering safety features actuation system. We reviewed 160 manual valves and 56 control/instrumentation equipment. The number of newly identified pre-accident human errors is 101. Among them, the number of those related to testing/maintenance tasks is 56. The number of those related to calibration tasks is 45. The number of those related to only shutdown operation is 10. It was shown that the pre-accident human errors related to only shutdown operation contributions to the core damage frequency of LPSD PSA model for the KSNP was negligible.The self-assessment results for the new HRA results of pre-accident human errors using the ANS LPSD PRA Standard show that above 80% items of its supporting requirements for post-accident human errors were graded as its Category II or III. It is expected that the HRA results for the pre-accident human errors presented in this study will be greatly helpful to improve the PSA quality for the domestic nuclear power plants because they have sufficient PSA quality to meet the Category II of supporting requirements for the postaccident human errors in the ANS LPSD PRA Standard.

  12. Permanent 125I-seed prostate brachytherapy: early prostate specific antigen value as a predictor of PSA bounce occurrence

    Science.gov (United States)

    2012-01-01

    Purpose To evaluate predictive factors for PSA bounce after 125I permanent seed prostate brachytherapy and identify criteria that distinguish between benign bounces and biochemical relapses. Materials and methods Men treated with exclusive permanent 125I seed brachytherapy from November 1999, with at least a 36 months follow-up were included. Bounce was defined as an increase ≥ 0.2 ng/ml above the nadir, followed by a spontaneous return to the nadir. Biochemical failure (BF) was defined using the criteria of the Phoenix conference: nadir +2 ng/ml. Results 198 men were included. After a median follow-up of 63.9 months, 21 patients experienced a BF, and 35.9% had at least one bounce which occurred after a median period of 17 months after implantation (4-50). Bounce amplitude was 0.6 ng/ml (0.2-5.1), and duration was 13.6 months (4.0-44.9). In 12.5%, bounce magnitude exceeded the threshold defining BF. Age at the time of treatment and high PSA level assessed at 6 weeks were significantly correlated with bounce but not with BF. Bounce patients had a higher BF free survival than the others (100% versus 92%, p = 0,007). In case of PSA increase, PSA doubling time and velocity were not significantly different between bounce and BF patients. Bounces occurred significantly earlier than relapses and than nadir + 0.2 ng/ml in BF patients (17 vs 27.8 months, p brachytherapy and young age were significantly associated to a higher risk of bounces but not to BF. Long delays between brachytherapy and PSA increase are more indicative of BF. PMID:22449081

    Purpose To evaluate prostate-cancer specific mortality (PCSM) in a cohort of high-risk patients treated with a permanent prostate brachytherapy approach, stratified by pre-treatment PSA. Material and methods 448 high-risk patients (NCCN criteria) underwent permanent prostate brachytherapy. High risk patients were stratified by pre-treatment PSA (≤ 10.0, 10.1-20, and > 20 ng/ml). Biochemical failure (BF), prostate cancer-specific mortality (PCSM), distant failure (DM), and overall mortality (OM) were assessed as a function of prognostic group. Multiple clinical, treatment, and dosimetric parameters were evaluated for impact on outcome. Results The 10-year OM, BF, and PCSM for the entire cohort were 28.5%, 13.3%, and 4.9%, respectively. At 10 years, PCSM was 2.5%, 10.7%, and 4.5% in the PSA ≤ 10, 10.1-20, and > 20 ng/ml groups, respectively. No statistically significant differences in BF or overall survival (OS) were noted when stratified by pre-treatment PSA. DF was the most common in the 10.1-20 ng/ml cohort (8.6% at 10 years). In multivariate analysis, PCSM was most closely related to percent positive biopsies (p = 0.001) and tobacco (p = 0.042). Conclusions High-risk prostate cancer treated with permanent prostate brachytherapy and supplemental external beam radiotherapy resulted in excellent long-term biochemical control and PCSM. Overall, PCSM was low in all cohorts but highest in the intermediate PSA group (10.1-20 ng/ml). PMID:28951747

    Full Text Available Purpose To evaluate the clinical outcome of a cohort of localized prostate cancer patients treate with 125-I permanent brachytherapy at the São José Hospital – CHLC, Lisbon. Materials and Methods A retrospective analysis was carried out on 429 patients with low and intermediate-risk of prostate adenocarcinoma, according to the recommendations of the EORTC, who underwent 125I brachytherapies in intraoperative dosimetry “real-time” system between September 2003 and September 2013. Results The mean follow-up was 71.98 months. Biochemical relapse of disease by rising PSA (Phoenix criterion was observed in 18 patients (4.2%. Through the application of Kaplan-Meier survival curves in this sample, the rate of survival at 6 years without biochemical relapse was higher than 95%. By Iog rank test comparing biochemical relapse with initial PSA (15-10 and <10 and Gleason values (7 and <7, there was no statistical difference (P=0.830 of the initial PSA in the probability of developing biochemical relapse. In relation to Gleason score, it was noted a statistical difference (P<0.05, demonstrating that patients with Gleason 7 are more likely to develop biochemical relapse. Conclusions Brachytherapy as monotherapy is at present an effective choice in the treatment of localized prostate adenocarcinoma. Biochemical relapses are minimal. The initial PSA showed no statistically difference in the rate of relapses, unlike the value Gleason, where it was demonstrated that patients with Gleason 7 have a higher probability of biochemical relapse. Cases with PSA bounce should be controlled before starting a salvage treatment.

  15. Disparity between state fish consumption advisory systems for Methylmercury and US Environmental Protection Agency recommendations: a case study of the South Central United States

    2015-01-01

    Fish consumption advisories are used to inform citizens in the United States about noncommercial game fish with hazardous levels of methylmercury (MeHg). The US Environmental Protection Agency (USEPA) suggests issuing a fish consumption advisory when concentrations of MeHg in fish exceed a human health screening value of 300 ng/g. However, states have authority to develop their own systems for issuing fish consumption advisories for MeHg. Five states in the south central United States (Arkansas, Louisiana, Mississippi, Oklahoma, and Texas) issue advisories for the general human population when concentrations of MeHg exceed 700 ng/g to 1000 ng/g. The objective of the present study was to estimate the increase in fish consumption advisories that would occur if these states followed USEPA recommendations. The authors used the National Descriptive Model of Mercury in Fish to estimate the mercury concentrations in 5 size categories of largemouth bass–equivalent fish at 766 lentic and lotic sites within the 5 states. The authors found that states in this region have not issued site-specific fish consumption advisories for most of the water bodies that would have such advisories if USEPA recommendations were followed. One outcome of the present study may be to stimulate discussion between scientists and policy makers at the federal and state levels about appropriate screening values to protect the public from the health hazards of consuming MeHg-contaminated game fish.

    2010-03-01

    Full Text Available Abstract Background Glioblastoma multiforme (GBM is the most aggressive and frequent brain tumor, albeit without cure. Although patient survival is limited to one year on average, significant variability in outcome is observed. The assessment of biomarkers is needed to gain better knowledge of this type of tumor, help prognosis, design and evaluate therapies. The neurodevelopmental polysialic acid neural cell adhesion molecule (PSA-NCAM protein is overexpressed in various cancers. Here, we studied its expression in GBM and evaluated its prognosis value for overall survival (OS and disease free survival (DFS. Methods We set up a specific and sensitive enzyme linked immunosorbent assay (ELISA test for PSA-NCAM quantification, which correlated well with PSA-NCAM semi quantitative analysis by immunohistochemistry, and thus provides an accurate quantitative measurement of PSA-NCAM content for the 56 GBM biopsies analyzed. For statistics, the Spearman correlation coefficient was used to evaluate the consistency between the immunohistochemistry and ELISA data. Patients' survival was estimated by using the Kaplan-Meier method, and curves were compared using the log-rank test. On multivariate analysis, the effect of potential risk factors on the DFS and OS were evaluated using the cox regression proportional hazard models. The threshold for statistical significance was p = 0.05. Results We showed that PSA-NCAM was expressed by approximately two thirds of the GBM at variable levels. On univariate analysis, PSA-NCAM content was an adverse prognosis factor for both OS (p = 0.04 and DFS (p = 0.0017. On multivariate analysis, PSA-NCAM expression was an independent negative predictor of OS (p = 0.046 and DFS (p = 0.007. Furthermore, in glioma cell lines, PSA-NCAM level expression was correlated to the one of olig2, a transcription factor required for gliomagenesis. Conclusion PSA-NCAM represents a valuable biomarker for the prognosis of GBM patients.

  5. Comparison between Use of PSA Kinetics and Bone Marrow Micrometastasis to Define Local or Systemic Relapse in Men with Biochemical Failure after Radical Prostatectomy for Prostate Cancer.

    Treatment of biochemical failure after radical prostatectomy for prostate cancer is largely empirically based. The use of PSA kinetics has been used as a guide to determine local or systemic treatment of biochemical failure. We here compared PSA kinetics with detection of bone marrow micrometastasis as methods to determine local or systemic relapse. A transversal study was conducted of men with biochemical failure, defined as a serum PSA >0.2ng/ml after radical prostatectomy. Consecutive patients having undergone radical prostatectomy and with biochemical failure were enrolled and clinical and pathological details were recorded. Bone marrow biopsies were obtained from the iliac crest and touch prints made, micrometastasis (mM) being detected using anti-PSA. The clinical parameters of total serum PSA, PSA velocity, PSA doubling time and time to biochemical failure, age, Gleason score and pathological stage were registered. A total of 147 men, mean age 71.6 ± 8.2 years, with a median time to biochemical failure of 5.5 years (IQR 1.0-6.3 years) participated in the study. Bone marrow samples were positive for micrometastasis in 98/147 (67%) of patients at the time of biochemical failure. The results of bone marrow micrometastasis detected by immunocytochemistry were not concordant with local relapse as defined by PSA velocity, time to biochemical failure or Gleason score. In men with a PSA doubling time of 2,5ng/ml at the time of biochemical failure the detection of bone marrow micrometastasis was significantly higher. The detection of bone marrow micrometastasis could be useful in defining systemic relapse, this minimally invasive procedure warranting further studies with a larger group of patients.

    As the main systems for managing totally about the operation, control, monitoring, measurement, and safety function in an emergency, instrumentation and control systems (I and C) in nuclear power plants have been digitalized gradually for the precise operation and its convenience. The digitalization of infrastructure makes systems vulnerable to cyber threats and hybrid attacks. According to ICS-CERT report, as time goes by, the number of vulnerabilities in ICS industries increases rapidly. Recently, due to the digitalization of I and C, it has begun to rise the need of cyber security in the digitalized I and C in NPPs. However, there are too many critical digital assets (CDAs) in NPPs. More than 60% of the total critical systems are digital system. Addressing more than 100 security controls for each CDA needs too much effort for both licensee and inspector. It is necessary to focus on more significant CDAs for effective regulation. Probabilistic Safety Analysis (PSA) results are analyzed in order to identify more significant CDAs which could evoke an accident of NPPs by digital malfunction or cyber-attacks. By eliciting minimal cut sets using fault tree analyses, accident-related CDAs are drawn. Also the CDAs that must be secured from outsiders are elicited in case of some accident scenario. It is expected that effective cyber security regulation based on the graded approach can be implemented. Furthermore, defense-in-depth of digital assets for NPPs safety can be built up. Digital technologies such as computers, control systems, and data networks currently play essential roles in modern NPPs. Further, the introduction of new digitalized technologies is also being considered. These digital technologies make the operation of NPPs more convenient and economical; however, they are inherently susceptible to problems such as digital malfunction of components or cyber-attacks. Recently, needs for cyber security on digitalized nuclear Instrumentation and Control (I and C
