PEN eNews 3(4) December 2013
PEN eNews is a monthly e-newsletter shared with the global PEN Community and created to help dietitians position themselves as leaders in evidence-based nutrition practice. In addition, users of the PEN System will find articles on the new evidence, resources and features available and how to maximize one's use of PEN.

Evidence-based Practice and Pseudoscience
What “counts” as evidence-based practice? Does referencing an article count as evidence-based practice? Is there a difference between arguments where evidence has been hand-picked to support their perspective, versus when evidence has been systematically examined and potential biases and conflicts are acknowledged? Do you observe “professionals” exploiting science and scientific jargon for their personal gain? With excellent communication skills, just about anyone is able to position themself as an intelligent-sounding, “evidence-based” expert. This makes a regulated health care professional’s job challenging, not to mention frustrating.

Welcome to the Irish Nutrition and Dietetics Association!
We are pleased to welcome in the Irish Nutrition and Dietetic Association in joining the Practice-based Evidence in Nutrition® Nutrition Community! We look forward to working with Ireland’s dietitians to expand the PEN® system making it their “go to” resource to support evidence-based dietetic practice.
How do I...interpret the copyright and updated years on PEN® client handouts?
For example, in the Food Sources of Omega-3 Fats handout, the copyright statement listed in the bottom right hand corner says “© 2009 Dietitians of Canada. All rights reserved” followed by Updated: 2013-10-15.Social Media Corner: The Paradoxes of Pop Science
Dr. Caulfield's article was originally published in Policy Options, http://www.irpp.org/en/po/the-age-of-man/the-paradoxes-of-pop-science/ © September 2013. It is reprinted here with permission from Policy Options.
Not surprisingly, companies selling dubious anti-aging products also frequently exploit the profile of stem cell research, which is one of the most exciting fields of scientific inquiry, and is also one that continues to receive a large amount of coverage in the popular press. One Web site, Stem Cell Beauty Innovations, for example, encapsulates all the science-language incongruities that have become endemic in today’s media landscape. The Web site refers to the use of “pluripotent stem cells” and “transcription factors” that “revitalize” the skin and allow for “increased levels of collagen, glycoproteins, and elastic fibers in the skin’s extra cellular matrix” — all for the purpose of “de-aging” the skin.

Why did we choose the name Practice-based Evidence in Nutrition®?
We caught up with PEN’s Director and a PEN® Evidence Analyst and asked – “Why was the name PEN: Practice-based Evidence in Nutrition® chosen?” Here is what Dr. Jayne Thirsk and Heather Petrie had to say.
The choice of PEN: Practice-based Evidence in Nutrition® was a deliberate one. We wanted to integrate the principle of basing one's practice on best evidence while ensuring that the application of evidence was informed by consideration of patients’ values, clinical experience and the practice context or circumstances that the care is being delivered in. “Practice-based” is also related to the foundational principle that PEN is practitioner-centered. The questions addressed in the knowledge pathways come from dietitians working on the front lines. PEN aims to address real issues faced in actual practice. Evidence statements in PEN consist of a summary and critical appraisal of research evidence and guidelines. However, PEN doesn’t just ask research questions, we ask practice questions. Hence, while PEN provides evidence syntheses, it also assists with the practical translation of that evidence by providing key practice points, practice guidance summaries, toolkits, client handouts (many of which are culturally adapted and translated into various languages) and professional tools and resources that are consistent with the evidence. - Montgomery K. How doctors think: clinical judgment and the practice of medicine. Oxford: Oxford University Press; 2006.
Combining the PEN® approach and nutrition practice guidelines– Why compromise, when you can have the best of both?
Forty four Australian and New Zealand dietitians specializing in cystic fibrosis (CF) are combining the PEN® approach with the creation of nutrition practice guidelines. This makes the 2012-2015 ‘Australian and New Zealand Cystic Fibrosis Nutrition Guideline Revision Project’ unique. These dietitians have also enlisted the support of an interdisciplinary steering committee to secure the success of this ambitious project. The interdisciplinary committee is comprised of medical specialists, allied health professionals, nurses, librarians and consumers. Expected outcomes include:
- a set of online and paper based resources that provide interdisciplinary CF care teams with accessible evidence-based answers to everyday nutrition practice questions and
- corresponding consumer handouts.
- The PEN® approach
- Paper-based nutrition practice guidelines
The PEN® approach- Succinct topic focus and use of clinical questions.
- An easily updatable evidence-based practice format.
- International dissemination of evidence-based information with systems to incorporate feedback from the international dietetics community.
- The ability to share the workload of critiquing and synthesising evidence, writing evidence summaries and grading of evidence practice points with dietitians from around the world.
- PEN® knowledge pathways are not easily accessible by other members of the multidisciplinary CF care team.
- Writing a PEN® knowledge pathway is unchartered territory for Australian and New Zealand dietitians.
- Health care systems and climatic conditions are different across the world. These differences may impact the nutritional care that can be provided to the CF population. Concerns were raised that the international nature of the PEN® approach might dilute issues that are pertinent to Australian and New Zealand CF dietitians.
- Useful document for dietetic students and new staff as it provided background information on all topics
- Collaborative Australian and New Zealand authorship. Previous collaboration between these countries has provided opportunities for learning, sharing of expertise, mentoring and support.
- CF nutrition guidelines have been evaluated against current practice via surveys since 1998
- It is difficult to update all sections of a guideline simultaneously.
- Format is a barrier to publication, and actual authorship may be hidden due to the acknowledgement going to the collective working group
- Dietitians Association of Australia and Dietitians New Zealand are investing organisational resources into the development of PEN® knowledge pathways rather than publishing guidelines.

Dietitians New Zealand Members Have Embraced PEN!
The first month of my appointment as DAA’s PEN® Translational Research Leader commenced with a flying start across the Tasman Sea to the New Zealand (NZ) Dietitians 2013 conference in Auckland. In a plenary session, a broad overview of PEN was provided highlighting PEN as one of the key membership benefits of Dietitians NZ, increasing awareness of the relevance of PEN to dietetics practice in all settings and encouraging contribution to PEN by our New Zealand colleagues. A PEN writing workshop was conducted for both experienced and novice PEN users. Leading Auckland dietitian Lisa Guest provided fabulous workshop assistance and showcased the Australian and New Zealand cystic fibrosis dietitians project and planned contribution to PEN.
Dietitians NZ members have embraced PEN with Google Analytics recently showing a dramatic increase in PEN site visits since the conference. There is currently active involvement from members of Dietitians NZ in several PEN writing teams as well as reviewing roles. We look forward to further collaboration in 2014.

RCTs in an Aboriginal Context:
We've all heard about the underrepresentation of women, minorities and people of low income in many clinical trials and the impact this can have on the generalizability of the research findings. In a recent paper from the Canadian National Collaborating Centre for Aboriginal Health, they highlight the under-representation of Aboriginals in RCT investigations - referring to it as a "silent bias". The authors of this report state: "…that to remedy existing health care disparities, researchers need to develop participatory, socially relevant, and culturally safe methods for conducting RCTs within First Nations, Métis, and Inuit communities."
