Supporting prostate cancer focal therapy: a multidisciplinary International Consensus of Experts (“ICE”)

Abstract:

Prostate cancer is a common malignancy among men, and the current screening, imaging and sampling approaches aim to detect early-stage, organ-confined disease. In such scenario, focal prostate cancer therapy currently relies on the index lesion concept as the dominant lesion that drives the disease natural history. Focal therapy demands the essential imaging and sampling techniques to strategically locate and qualify the disease, but, despite advances in technology, prostate imaging and biopsy have several limitations that need to be overcome if focal therapy is to be developed further. The I Prostate Cancer Focal Treatment International Symposium was convened to foster discussion on this topic that sits at the crossroads of multiple disciplines (Urology, Pathology, Radiology, Radiation Oncology and Medical Oncology) all of which were represented for this comprehensive multidisciplinary review of the current literature.     

Is there nothing beyond postmodernism and ‘the theoretical Other’? The need for balancing universalism and diversity in social work

In his article, 'Against difference and diversity in social work: the case of human rights', Stephen Webb captures several important problems concerning the application of a postmodern human rights perspective in social work. Although accepting Webb's diagnosis, for example that the postmodern discourse neglects basic structural conditions essential for understanding social problems and thus leads to a policy of symbols and rhetoric, this article argues that Webb reifies the perspectives of diversity and universalism and misses the need for balancing these aspects in the practice of social work. Some general argumentative techniques in the postmodern discourse are identified, and it is argued that several of Webb's conclusions are reached via those argumentative techniques, particularly when it comes to his claim that the philosopher Alain Badiou could play a central role for social work. The possibility of implementing in social work general philosophical programmes such as Alain Badiou's is questioned.

A graph coloring approach for image segmentation

In this paper we develop a segmentation scheme for digital images based upon an iterative binary coloring technique that takes into account changing behavior of adjacent pixels. The output is a hierarchical structure of images which allows a better understanding of complex images. In particular, we propose two algorithms that should be considered as image preprocessing techniques.

Graphical Techniques for Selecting Explanatory Variables for Time Series Data

Bayesian model building techniques are developed for data with a strong time series structure and possibly exogenous explanatory variables that have strong explanatory and predictive power. The emphasis is on finding whether there are any explanatory variables that might be used for modelling if the data have a strong time series structure that should also be included. We use a time series model that is linear in past observations and that can capture both stochastic and deterministic trend, seasonality and serial correlation. We propose the plotting of absolute predictive error against predictive standard deviation. A series of such plots is utilized to determine which of several nested and non-nested models is optimal in terms of minimizing the dispersion of the predictive distribution and restricting predictive outliers. We apply the techniques to modelling monthly counts of fatal road crashes in Australia where economic, consumption and weather variables are available and we find that three such variables should be included in addition to the time series filter. The approach leads to graphical techniques to determine strengths of relationships between the dependent variable and covariates and to detect model inadequacy as well as determining useful numerical summaries.
