Establishing prostate cancer patient derived xenografts: Lessons learned from older studies

Background Understanding the progression of prostate cancer to androgen-independence/castrate resistance and development of preclinical testing models are important for developing new prostate cancer therapies. This report describes studies performed 30 years ago, which demonstrate utility and shortfalls of xenografting to preclinical modeling. Methods We subcutaneously implanted male nude mice with small prostate cancer fragments from transurethral resection of the prostate (TURP) from 29 patients. Successful xenografts were passaged into new host mice. They were characterized using histology, immunohistochemistry for marker expression, flow cytometry for ploidy status, and in some cases by electron microscopy and response to testosterone. Two xenografts were karyotyped by G-banding. Results Tissues from 3/29 donors (10%) gave rise to xenografts that were successfully serially passaged in vivo. Two, (UCRU-PR-1, which subsequently was replaced by a mouse fibrosarcoma, and UCRU-PR-2, which combined epithelial and neuroendocrine features) have been described. UCRU-PR-4 line was a poorly differentiated prostatic adenocarcinoma derived from a patient who had undergone estrogen therapy and bilateral castration after his cancer relapsed. Histologically, this comprised diffusely infiltrating small acinar cell carcinoma with more solid aggregates of poorly differentiated adenocarcinoma. The xenografted line showed histology consistent with a poorly differentiated adenocarcinoma and stained positively for prostatic acid phosphatase (PAcP), epithelial membrane antigen (EMA) and the cytokeratin cocktail, CAM5.2, with weak staining for prostate specific antigen (PSA). The line failed to grow in female nude mice. Castration of three male nude mice after xenograft establishment resulted in cessation of growth in one, growth regression in another and transient growth in another, suggesting that some cells had retained androgen sensitivity. The karyotype (from passage 1) was 43–46, XY, dic(1;12)(p11;p11), der(3)t(3:?5)(q13;q13), -5, inv(7)(p15q35) x2, +add(7)(p13), add(8)(p22), add(11)(p14), add(13)(p11), add(20)(p12), -22, +r4[cp8]. Conclusions Xenografts provide a clinically relevant model of prostate cancer, although establishing serially transplantable prostate cancer patient derived xenografts is challenging and requires rigorous characterization and high quality starting material. Xenografting from advanced prostate cancer is more likely to succeed, as xenografting from well differentiated, localized disease has not been achieved in our experience. Strong translational correlations can be demonstrated between the clinical disease state and the xenograft model

Learnings, case studies and guidelines for establishing shared and collaborative service delivery in the non-government sector: Evaluation of the Multi-Tenant Service Centre (MTSC) Pilots Project

This report presents learnings, case studies, guidelines and resources for non-government organisations that are planning to implement shared or collaborative arrangements with other agencies. It summarises results from an evaluation of the implementation phase of the Multi-Tenant Service Centre (MTSC) Pilots Project, which was completed in June 2008. This evaluation shows that developing and implementing shared and collaborative arrangements is a complex process that presents many risks, challenges and barriers to success, but can have many potential benefits for non government organisations. As this report makes clear, there is no ‘one size fits all’ approach to this process. The MTSC Pilots Project was conducted by the Department of Communities (DoC), Queensland Government, as part of its Strengthening Non-Government Organisations strategy. The objective of the MTSC Pilots initiative was to co-locate separate service providers in an appropriately located centre, operating with effective and transparent management, which enabled service providers to improve client services. Three MTSC consortiums in Mackay, Caboolture and Toowoomba were selected as the pilots over a four year period from 2006 – 2010.

Energy Efficiency Graduate Attributes Project: Final Report

The Energy Efficiency (EE) Graduate Attributes Project focuses on engineering as a priority profession that has a significant role to play in addressing energy demand and supply issues in Australia. Specifically, this project aims to support embedding EE knowledge and skills throughout the engineering undergraduate curriculum, to help build capacity within the Australian workforce across major sectors of the economy, from mining, manufacturing and industrial applications to design, construction, maintenance and retrofitting built environments. The resultant report is intended to assist in future consultation with key groups such as Engineers Australia (EA), the Australian Council of Engineering Deans (ACED) and the eight EA colleges, to support systemic curriculum renewal and promote the design and development of high quality EE engineering education resources. The project is based on a whole-of-program outcomes-based approach to curriculum renewal, creating a transparent framework for integrating EE. This comprises collaborative consideration by academics and professional engineers who have experience in teaching and practising EE, to identify what students should learn to be equipped with relevant competencies by the time they graduate.

Patient satisfaction from two studies of collaborative doctor : pharmacist prescribing in Australia

Background Pharmacist prescribing has been introduced in several countries and is a possible future role for pharmacy in Australia. Objective To assess whether patient satisfaction with the pharmacist as a prescriber, and patient experiences in two settings of collaborative doctor-pharmacist prescribing may be barriers to implementation of pharmacist prescribing. Design Surveys containing closed questions, and Likert scale responses, were completed in both settings to investigate patient satisfaction after each consultation. A further survey investigating attitudes towards pharmacist prescribing, after multiple consultations, was completed in the sexual health clinic. Setting and Participants A surgical pre-admission clinic (PAC) in a tertiary hospital and an outpatient sexual health clinic at a university hospital. Two hundred patients scheduled for elective surgery, and 17 patients diagnosed with HIV infection, respectively, recruited to the pharmacist prescribing arm of two collaborative doctor-pharmacist prescribing studies. Results Consultation satisfaction response rates in PAC and the sexual health clinic were 182/200 (91%) and 29/34 (85%), respectively. In the sexual health clinic, the attitudes towards pharmacist prescribing survey response rate were 14/17 (82%). Consultation satisfaction was high in both studies, most patients (98% and 97%, respectively) agreed they were satisfied with the consultation. In the sexual health clinic, all patients (14/14) agreed that they trusted the pharmacist’s ability to prescribe, care was as good as usual care, and they would recommend seeing a pharmacist prescriber to friends. Discussion and Conclusion Most of the patients had a high satisfaction with pharmacist prescriber consultations, and a positive outlook on the collaborative model of care in the sexual health clinic.

On the topic of competency and excellence of our graduate engineers

Problem solving is an essential element of civil engineering education. It has been I observed that students are best able to understand civil engineering theory when there is a ' practical application of it. Teaching theory alone has led to lower levels of comprehension and motivation and a correspondingly higher rate of failure and "drop-out". This paper analyses the effectiveness of introducing practical design projects at an early stage within a civil engineering undergraduate program at Queensland University of Technology. In two of the essential basic subjects, Engineering Mechanics and Steel Structures, model projects which simulate realistic engineering exercises were introduced. Students were required to work in small groups to analyse, design and build the lightest I most efficient model bridges made of specific materials such as spaghetti, drinking straw, paddle pop sticks and balsa wood and steel columns for a given design loading/target capacity. The paper traces the success of the teaching strategy at each stage from its introduction through to the final student and staff evaluation.

Strategies for teaching evidence-based practice to undergraduate health students: A systematic review protocol

Review question/objective The objective of this review is to find, critically appraise and synthesize the available quantitative evidence on the effectiveness of interventions that promote successful teaching of the evidence-based practice process in undergraduate health students, in preparation for them to become professional evidence-based practitioners. More specifically, the question that this review seeks to answer is: What is the effectiveness of teaching strategies for evidence-based practice for undergraduate health students? Inclusion criteria Types of participants This review will consider studies that include undergraduate health students from any undergraduate health discipline, including but not limited to medicine, nursing and allied health. Post graduate and post-registration students will not be included. Types of interventions This review will consider studies that evaluate strategies or interventions aimed at teaching any or all of the five steps of evidence-based practice, namely asking a structured clinical question; collecting the best evidence available; critically appraising the evidence to ensure validity, relevance and applicability; applying or integrating the results into clinical practice, and evaluating outcomes. The strategy may take place solely within a tertiary education environment or may be combined with a clinical setting. Types of outcomes This review will consider studies that include the following outcome measures: evidence-based practice behavior, knowledge, skills, attitudes, self-efficacy (or self-confidence), beliefs, values, intention to use evidence-based practice (future use) and confidence levels. Tools used to measure these outcomes will be assessed for reported validity, reliability and generalizability. Outcomes will be measured during the student’s education period up to graduation. If studies are conducted across different year levels this will be taken into account during analysis and reported accordingly.

Are Australian homes liveable and adaptable for Muslim families? - Six case studies in Brisbane

This paper investigates how Muslims living in Brisbane live within their current Australian homes and the liveability and adaptability of these homes from the perspective of home dwellers with respect to their Islamic faiths, cultural traditions and lifestyle. A qualitative case study approach was used to gather information about Muslims’ use of domestic spaces through their lived experiences, within an Australian context. Six participants were interviewed, including: a) three Muslim families residing in one suburb of Brisbane, and; b) three international Muslim students living in three different Brisbane suburbs. These cases indicate that apart from minor difficulties, case study participants were able to perform their daily activities within their current homes through various adaptations made to ensure their respective domestic domains provided their families with privacy and a sense of security and safety. Insight gained from these cases suggest the need for more research into the homes of Muslims homes within an Australian context and the development of culturally adaptable housing as a means of meeting the diverse needs of modern Australian multicultural society.

ICT in teacher education in the age of AITSL

This paper is drawn from a 2012-2013 OLT National Teaching Fellowship investigating the agencies impacting on whole-of course curriculum design in initial teacher education. The chief of these is AITSL (Australian Institute for Teaching and School Leadership) through the Australian Professional Standards for Teachers at Graduate level and the Program Accreditation Standards. This paper will begin with a discussion of the requirements on both beginning teachers and initial teacher education programs in regard to ICT (both content and pedagogy). It will then present case studies from four universities whose degree programs have been approved for implementation in 2014. It will focus on how each institution has responded to the APST as well as accreditation requirements. This will be based on responses to surveys to selected institutions and with one on one interviews to capture rich data. From this, it will draw a contemporary profile of how institutions are rising to the real requirements of ICT pedagogy within the regulatory constraints now in place. The methodology employed is qualitative and is based on document analysis enriched by interview data. It is important to know, as a profession, how future teachers are being introduced to and immersed in digital learning environments.
