Abstract

Objectives To assess survival of patients with muscle-invasive bladder cancer (MIBC) who underwent radical cystectomy (RC) with or without neo-adjuvant chemotherapy (NAC) according to the pathological response at RC. Methods 965 patients with MIBC (cT2-4aN0M0) who underwent RC with or without NAC were analyzed. Among the collected data were comorbidity, clinical and pathological tumor stage, tumor grade, nodal status (y)pN, and OS. Case–control matching of 412 patients was performed to compare oncological outcomes. Kaplan–Meier curves were created to estimate OS for patients who underwent RC with or without NAC, and for those with complete response (pCR), partial response (pPR), or residual or progressive disease (PD). Results Patients with a pCR or pPR at RC, with or without NAC, had better OS than patients who had PD (both p values p p = 0.023). Conclusions This study showed that patients with MIBC who underwent NAC with RC had a significant better OS than those who underwent RC only. The proportion of patients with a pCR was higher in those who received NAC and RC than in those who were treated by RC only. The favorable OS rate in the NAC and RC cohort was probably attributed to the higher observed pCR rate.

Abstract

Background: Radical cystectomy with pelvic lymph node dissection is the recommended treatment in non-metastatic muscle-invasive bladder cancer (MIBC). In randomised trials, robot-assisted radical cystectomy (RARC) showed non-inferior short-term oncological outcomes compared with open radical cystectomy (ORC). Data on intermediate and long-term oncological outcomes of RARC are limited. Objective: To assess the intermediate-term overall survival (OS) and recurrence-free survival (RFS) of patients with MIBC and high-risk non-MIBC (NMIBC) who underwent ORC versus RARC in clinical practice. Methods and materials: A nationwide retrospective study in 19 Dutch hospitals including patients with MIBC and high-risk NMIBC treated by ORC (n = 1086) or RARC (n = 386) between January 1, 2012 and December 31, 2015. Primary and secondary outcome measures were median OS and RFS, respectively. Survival outcomes were estimated using Kaplan-Meier curves. A multivariable Cox regression model was developed to adjust for possible confounders and to assess prognostic factors for survival including clinical variables, clinical and pathological disease stage, neoadjuvant therapy and surgical margin status. Results: The median follow-up was 5.1 years (95% confidence interval ([95%CI] 5.0–5.2). The median OS after ORC was 5.0 years (95%CI 4.3–5.6) versus 5.8 years after RARC (95%CI 5.1–6.5). The median RFS was 3.8 years (95%CI 3.1–4.5) after ORC versus 5.0 years after RARC (95%CI 3.9–6.0). After multivariable adjustment, the hazard ratio for OS was 1.00 (95%CI 0.84–1.20) and for RFS 1.08 (95%CI 0.91–1.27) of ORC versus RARC. Patients who underwent ORC were older, had higher preoperative serum creatinine levels and more advanced clinical and pathological disease stage. Conclusion: ORC and RARC resulted in similar intermediate-term OS and RFS in a cohort of almost 1500 MIBC and high-risk NMIBC.

Abstract

Background: Although guidelines exist for advanced and variant bladder cancer management, evidence is limited/conflicting in some areas and the optimal approach remains controversial. Objective: To bring together a large multidisciplinary group of experts to develop consensus statements on controversial topics in bladder cancer management. Design: A steering committee compiled proposed statements regarding advanced and variant bladder cancer management which were assessed by 113 experts in a Delphi survey. Statements not reaching consensus were reviewed; those prioritised were revised by a panel of 45 experts prior to voting during a consensus conference. Setting: Online Delphi survey and consensus conference. Participants: The European Association of Urology (EAU), the European Society for Medical Oncology (ESMO), experts in bladder cancer management. Outcome measurements and statistical analysis: Statements were ranked by experts according to their level of agreement: 1-3 (disagree), 4-6 (equivocal), and 7-9 (agree). A priori (level 1) consensus was defined as ≥70% agreement and ≤15% disagreement, or vice versa. In the Delphi survey, a second analysis was restricted to stakeholder group(s) considered to have adequate expertise relating to each statement (to achieve level 2 consensus). Results and limitations: Overall, 116 statements were included in the Delphi survey. Of these statements, 33 (28%) achieved level 1 consensus and 49 (42%) achieved level 1 or 2 consensus. At the consensus conference, 22 of 27 (81%) statements achieved consensus. These consensus statements provide further guidance across a broad range of topics, including the management of variant histologies, the role/limitations of prognostic biomarkers in clinical decision making, bladder preservation strategies, modern radiotherapy techniques, the management of oligometastatic disease, and the evolving role of checkpoint inhibitor therapy in metastatic disease. Conclusions: These consensus statements provide further guidance on controversial topics in advanced and variant bladder cancer management until a time when further evidence is available to guide our approach. Patient summary: This report summarises findings from an international, multistakeholder project organised by the EAU and ESMO. In this project, a steering committee identified areas of bladder cancer management where there is currently no good-quality evidence to guide treatment decisions. From this, they developed a series of proposed statements, 71 of which achieved consensus by a large group of experts in the field of bladder cancer. It is anticipated that these statements will provide further guidance to health care professionals and could help improve patient outcomes until a time when good-quality evidence is available.

Abstract

Alternative splicing (AS) of pre-mRNA is a critical component of transcriptional regulation that diversifies the cellular proteome. The Serine-Arginine Protein Kinases (SRPK) initiate early events in AS. Using conditional knockout mice (cKO), we demonstrated the importance of the X-linked gene Srpk3 in B lymphocyte development and in response to immunization in vivo. Significantly decreased numbers of immature and mature B cells were observed in Srpk3-cKO BM relative to wild-type (WT). Immunization of Srpk3-cKO mice with a T lymphocyte-independent type-2 antigen elicited greatly reduced amounts of specific IgG3. Srpk3 deletion resulted in hundreds of differentially spliced mRNAs in B cells, including mRNAs encoding proteins associated with signaling pathways and mitochondrial function. Several alternative splicing outcomes in Srpk3-cKO cells are due to altered splicing regulation of SR proteins. We conclude that Srpk3 is an immunomodulatory kinase that controls humoral immunity via its regulation of pre-mRNA splicing, antibody production, and metabolism in B cells.One Sentence SummarySRPK3 regulates alternative splicing of pre-mRNA that is crucial for B cell development, activation and antibody responses.

15. The frequency dependence of hygro-expansive scaling of oak

Abstract

Fluctuations in the ambient relative humidity are often cyclic of nature, composed of a wide variety of frequencies. Variations may be as fast as one minute or as slow as a complete season. A wooden object exposed to these fluctuations exchanges moisture with the air, resulting in a change in the local moisture content of the wood. Since moisture penetration is affected by the timescale of the changes in ambient conditions, so are processes caused by moisture content variations. Moisture content variations cause dimensional changes of a wooden object, which, if mechanically restrained, lead to a buildup of stresses and ultimately to damage. It is therefore important to predict the frequency behavior of moisture content and expansion in wood. In the presented study, experiments are conducted in which the moisture content and expansion of oak cubes with different sizes is measured during sinusoidal relative humidity fluctuations with different frequencies. The amplitude in moisture content and expansion is shown to be simply scalable based on sample size only. Derived diffusion coefficients are in agreement with literature values, although the experimental frequency behavior is shown to deviate qualitatively from diffusive frequency behavior.

Abstract

BACKGROUND: Although guidelines exist for advanced and variant bladder cancer management, evidence is limited/conflicting in some areas and the optimal approach remains controversial. OBJECTIVE: To bring together a large multidisciplinary group of experts to develop consensus statements on controversial topics in bladder cancer management. DESIGN: A steering committee compiled proposed statements regarding advanced and variant bladder cancer management which were assessed by 113 experts in a Delphi survey. Statements not reaching consensus were reviewed; those prioritised were revised by a panel of 45 experts prior to voting during a consensus conference. SETTING: Online Delphi survey and consensus conference. PARTICIPANTS: The European Association of Urology (EAU), the European Society for Medical Oncology (ESMO), experts in bladder cancer management. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Statements were ranked by experts according to their level of agreement: 1-3 (disagree), 4-6 (equivocal), and 7-9 (agree). A priori (level 1) consensus was defined as ≥70% agreement and ≤15% disagreement, or vice versa. In the Delphi survey, a second analysis was restricted to stakeholder group(s) considered to have adequate expertise relating to each statement (to achieve level 2 consensus). RESULTS AND LIMITATIONS: Overall, 116 statements were included in the Delphi survey. Of these statements, 33 (28%) achieved level 1 consensus and 49 (42%) achieved level 1 or 2 consensus. At the consensus conference, 22 of 27 (81%) statements achieved consensus. These consensus statements provide further guidance across a broad range of topics, including the management of variant histologies, the role/limitations of prognostic biomarkers in clinical decision making, bladder preservation strategies, modern radiotherapy techniques, the management of oligometastatic disease, and the evolving role of checkpoint inhibitor therapy in metastatic disease.

21. Dynamics of heterogeneous crosslinking in room temperature vulcanizing poly(dimethyl siloxane) and its dependence on moisture supply

Abstract

The influence of moisture supply on the crosslinking rate in room temperature vulcanizing poly(dimethyl siloxane) is investigated using spatially resolved 1H nuclear magnetic resonance relaxometry. Using this technique, we observe heterogeneous crosslinking manifested in a front moving into the material from the exposed surface, which separates the crosslinked and uncrosslinked parts of the material. The presence of a sharp boundary indicates that moisture transport towards the front is the limiting factor in the crosslinking process. As a result, the moisture supply controls the crosslinking front velocity, which we capture in a diffusion-reaction model. Reasonable agreement is found between the front diffusivity retrieved directly from nuclear magnetic resonance experiments and calculated values using independently measured properties of the crosslinked silicone rubber. This result demonstrates the direct relationship between exposure moisture content, moisture diffusion, and crosslink density on the crosslinking front dynamics in room temperature vulcanizing poly(dimethyl siloxane).

Abstract

BACKGROUND: Although guidelines exist for advanced and variant bladder cancer management, evidence is limited/conflicting in some areas and the optimal approach remains controversial. OBJECTIVE: To bring together a large multidisciplinary group of experts to develop consensus statements on controversial topics in bladder cancer management. DESIGN: A steering committee compiled proposed statements regarding advanced and variant bladder cancer management which were assessed by 113 experts in a Delphi survey. Statements not reaching consensus were reviewed; those prioritised were revised by a panel of 45 experts before voting during a consensus conference. SETTING: Online Delphi survey and consensus conference. PARTICIPANTS: The European Association of Urology (EAU), the European Society for Medical Oncology (ESMO), experts in bladder cancer management. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Statements were ranked by experts according to their level of agreement: 1-3 (disagree), 4-6 (equivocal), 7-9 (agree). A priori (level 1) consensus was defined as ≥70% agreement and ≤15% disagreement, or vice versa. In the Delphi survey, a second analysis was restricted to stakeholder group(s) considered to have adequate expertise relating to each statement (to achieve level 2 consensus). RESULTS AND LIMITATIONS: Overall, 116 statements were included in the Delphi survey. Of these, 33 (28%) statements achieved level 1 consensus and 49 (42%) statements achieved level 1 or 2 consensus. At the consensus conference, 22 of 27 (81%) statements achieved consensus. These consensus statements provide further guidance across a broad range of topics, including the management of variant histologies, the role/limitations of prognostic biomarkers in clinical decision making, bladder preservation strategies, modern radiotherapy techniques, the management of oligometastatic disease and the evolving role of checkpoint inhibitor therapy in metastatic disease. CONCLUSIONS: These consensus

26. Moisture transport in pine wood during one-sided heating studied by NMR

Abstract

The quantification of moisture transport in heated wood is relevant to several fields, e.g. for lumber drying and processing and for fire safety risk assessment. We present non-destructive and simultaneous measurements of the moisture content and temperature distributions in pine wood during unilateral exposure to a heat source. The moisture content is measured by a nuclear magnetic resonance setup specifically built for the evaluation of moisture transport in porous materials at elevated temperatures. Temperature profiles are obtained by thermocouples placed at different distances from the exposed surface. While the temperature rises, a peak in the moisture content is formed, which travels towards the unexposed surface. The velocity of the moisture content peak depends on the principal direction in which transport occurs, as confirmed by experiments. Numerical simulations of moisture transport are performed which can qualitatively reproduce the behavior observed in experiments. Moreover, several characteristics, such as the timescale and non-linearity of the moisture peak position, are well captured. The influence of several input parameters, such as the permeability and diffusion coefficient, on the moisture peak dynamics is elaborately explored.

27. Moisture penetration in oak during sinusoidal humidity fluctuations studied by NMR

Abstract

Most natural fluctuations in relative humidity are cyclic of nature, e.g. daily or seasonal. During these fluctuations, hygroscopic materials exchange moisture with the surrounding air. The penetration of moisture into the material depends on the frequency of the fluctuation, but also on the transport characteristics of the material. Here we present an experimental study on the penetration depth of moisture in oak during sinusoidal relative humidity fluctuations, covering a wide range of frequencies. Using nuclear magnetic resonance, we show that the amplitude in moisture content decreases exponentially from the exposed surface. The slope of the decay on a logarithmic scale provides the diffusion coefficient in the three principal directions of wood (longitudinal, radial, tangential), which are in good agreement with literature values. Furthermore, we show the influence of the moisture content range on the decay in amplitude by performing experiments in different relative humidity ranges. Numerical experiments are performed to assess the dependence of moisture penetration on different model parameters.

Abstract

The water sorption isotherm of materials is of great importance to predict their durability. Many different methods are used in the literature to measure this water sorption isotherm. Chloride present in concrete elements/structures e.g. in marine exposure, can change the water sorption of the material. In this paper, the water sorption isotherm of a standard mortar with and without chloride is measured with a hygroscopic method. The chloride penetration into the sample is obtained by the vacuum saturation method. Subsequently the sample is placed in a glass vessel and dried. By injecting a known amount of water into the vessel, the water evaporates and is partly adsorbed by the sample until an equilibrium state is reached. With the known amount of the injected water into the vessel, the humidity inside the vessel and the volume of the vessel, one point of the adsorption isotherm is determined. For measuring the next point, more water is injected into the vessel. More points are measured in the same manner until the sample is saturated and with this the adsorption isotherm is completed. Afterwards, the measurement of the desorption isotherm starts with blowing dry air with a known flow, humidity and duration into the vessel. After reaching equilibrium, the first point of the desorption curve is measured. The next point is measured by blowing more dry air into the vessel. This continues until the sample is completely dry and with it the desorption isotherm is also completed.

34. A model describing water and salt migration in concrete during wetting/drying cycles

Author

Arends, T., Taher, A., van der Zanden, A.J.J., Brouwers, H.J.H., Bilek, V., Kersner, Z., Built Environment, and Building Materials

Abstract

In order to predict the life span of concrete structures, models describing the migration of chloride are needed. In this paper, a start is made with a simple, theoretical model describing water and chloride transport in a concrete sample. First, transport of water in concrete is considered with Fick’s second law of diffusion, which describes the time-evolution of the water content. Chloride can be transported through concrete by advection with water and by diffusion due to a difference in the chloride concentration of the pore solution. Furthermore, chloride can be bound to the surface of the pore walls. This bound chloride is immobile, thus unavailable for transport. The result is a partial differential equation for the time-evolution of the chloride concentration, coupled to the partial differential equation for water transport. This partial differential equation is solved using the Crank-Nicolson implicit method for a situation in which chloride enters, and in a certain extent also leaves the sample. Because the goal is to describe the migration behavior in the sample during wetting and drying cycles, the sample gets wet during one half of a day and dries during the other half.

Abstract

Qualification testing of photovoltaic modules is a set of well-defined accelerated stress tests with strict pass/fail criteria based on functionality / performance, safety / insulation and visual requirements. This paper, third in series from the Photovoltaic Testing Laboratory of ASU / TUV Rheinland PTL, compares the overall failure rates obtained in three consecutive periods: 1997-2005, 2005- 2007 and 2007-2009. This paper also presents a distribution of failures, for the 2007-2009 period, among the four pass criteria defined in the standard: Visual failure (for example, extensive delamination), dry insulation failure (safety issue), wet resistance failure (safety issue) and performance failure (power drop). © 2010 IEEE.

Abstract

Met samenvatting in het Engels onder de titel Exhaled nitric oxide in comparison with histamine bronchoprovocation test.; Met literatuuropgave., Momenteel is in het Centraal Militair Hospitaal (CMH) de histamineprovocatietest de standaardtest om bronchiale hyperreactiviteit aan te tonen. Het is een invasieve meting. De histamineprovocatietest is net als metacholine een directe bronchiale provocatietest. Directe bronchiale provocatietests maken gebruik van stoffen die werken op effectorcellen, zoals onder andere bronchiale spiercellen. Op deze cellen liggen specifieke receptoren waar deze stoffen zich aan binden. Via een intracellulair mechanisme veroorzaken deze bindingen een verhoging van Ca2+ in de cel, die uiteindelijk verantwoordelijk is voor contractie van de bronchiale spiercellen, wat bronchusobstructie geeft.
