Age and total and free prostate-specific antigen levels for predicting prostate volume in patients with benign prostatic hyperplasia

Objectives: To investigate the predictive values of free prostate-specific antigen (fPSA), total PSA (tPSA) and age on the prostate volume.

Methods: The data of 2148 patients with lower urinary tract symptoms were analyzed retrospectively. The patients who had transrectal ultrasonography guided 10 core biopsies owing to the findings obtained on digital rectal examination and presence of high PSA levels (PSA?=?2.5–10?ng/dl), and proven to have BPH histopathologically were included in the study. Age, tPSA, fPSA and the prostate volumes (PV) of the patients were noted.

Results: One thousand patients that fulfilled the inclusion criteria were included in the study. The PV of the patients were significantly correlated with age, tPSA and fPSA (p?r?=?0.307, p?r?=?0.382, p?r?=?0.296, respectively). On linear regression model, fPSA was found as a stronger predictive for PV (AUC?=?0.75, p?p?p?=?0.013).

Conclusions: Although tPSA is an important prognostic factor for predicting PV, the predictive value of fPSA is higher. PV can easily be predicted by using age, and serum tPSA and fPSA levels.     

100 key research questions for the post‐2015 development agenda

The Sustainable Development Goals (SDGs) herald a new phase for international development. This article presents the results of a consultative exercise to collaboratively identify 100 research questions of critical importance for the post‐2015 international development agenda. The final shortlist is grouped into nine thematic areas and was selected by 21 representatives of international and non‐governmental organisations and consultancies, and 14 academics with diverse disciplinary expertise from an initial pool of 704 questions submitted by 110 organisations based in 34 countries. The shortlist includes questions addressing long‐standing problems, new challenges and broader issues related to development policies, practices and institutions. Collectively, these questions are relevant for future development‐related research priorities of governmental and non‐governmental organisations worldwide and could act as focal points for transdisciplinary research collaborations.     

Visualizing ‘community’: an experiment in participatory photography among Kurdish diasporic workers in London

Most accounts of research methods in academic journals give an impression that research progresses in an orderly, logical and linear manner. Yet, in reality it is often more ‘messy’ than we admit. This paper reports on an experiment on the use of visual photographic methods in a study of Kurdish migrant workers in London who have had problems at work. The aim was to understand the type of problems workers faced and how they attempted to solve or deal with the issues they encountered. We were interested in the extent to which workers looked to local communities for support and if or how their identity impacted on the actions they took. The use of participant‐generated photography developed while the research was in progress and was utilized in addition to individual and group interviews in order to explore if this was helpful (to us and to research participants) in explaining issues, such as identity and ‘community’, which can often be difficult to verbalize or articulate. As a first foray into incorporating visual methods we struggled at first with ways to explain to participants the type of data we wanted, before learning that it was important to ‘lose control’ and allow participants to ‘speak’ for themselves using the lens of their cameras. The paper explores theoretical justifications that influenced our approach in our first attempt at participatory photography. It will look at the use of images constructed by research participants and how these were used in focus group situations to explore how or whether individual meanings of work, identity, community and belonging have resonance in the wider Kurdish community.

Founder's background as a catalyst for social entrepreneurship

Social entrepreneurship has a long history of practice worldwide. However, the concept has become widely popular among researchers over the last two decades. Despite this popularity, less is known about the process, which leads to becoming a social entrepreneur. Barendsen and Gardner's study shows that many social entrepreneurs have traumatic experience in their early lives; however, there are no supporting studies investigating the impact of the background of founders on the founding decision of their entities. Because of that we utilized the models of theory of planned behavior as well as the concept of imprinting to explain the process that leads to entrepreneurial behavior. The purpose of our study is to investigate the life stories of some Turkish social entrepreneurs, and to explore which factors in these people's backgrounds may have contributed to their decisions to establish their foundations.
