Focus group study: selection of appropriate parenting curricula for social service clients at the Helen Ross McNabb Children and Youth Center
No full textPlan BStudies have found positive results with parent education on adolescent risk taking behaviors, behavioral problems, and family relationships. There are a large number of parenting curricula available to educators and a very limited number of sources to assist educators in selecting an appropriate curriculum for their target audience. The purpose of this research was to complete qualitative evaluations of three parent education curricula for possible purchase by the Helen Ross McNabb Children and Youth Center in Knoxville, TN. The researcher and the center as appropriate for the study mutually agreed upon three parent education curricula. A focus group of program coordinators at the Center was conducted. These coordinators serve a parent population. The focus group was held for a forty-five minute period. During this meeting participants were asked structured questions designed to identify components that would be important to the group when making a purchase of parent educational curriculum. The meeting was audio taped and then used to compile a list of criteria important to the group. The list was returned to the participants and they were asked to rank the importance of each item on a five-point Likert scale. The weighted averages were then used as an instrument with which to evaluate the selected curricula. Because it was difficult to tell from web sites and catalogs exactly what the programs contained, the companies offering the curricula were contacted and asked which components their programs met. Two of the three programs contacted responded by answering each of the questions. These programs were evaluated using the designed instrument and recommendations where made. This instrument should be used with caution, as it may not generalize to needs of specific programs. The results of the research indicated a need for companies offering curricula to make more information available to educators and for educators to have better tools when making decisions between curricula programs

MRI for peripheral artery disease: Introductory physics for vascular physicians
No full text Magnetic resonance imaging (MRI) has advanced significantly in the past decade and provides a safe and non-invasive method of evaluating peripheral artery disease (PAD), with and without using exogenous contrast agents. MRI offers a promising alternative for imaging patients but the complexity of MRI can make it less accessible for physicians to understand or use. This article provides a brief introduction to the technical principles of MRI for physicians who manage PAD patients. We discuss the basic principles of how MRI works and tailor the discussion to how MRI can evaluate anatomic characteristics of peripheral arterial lesions. </jats:p
The current status of oncolytic viral therapy for head and neck cancer
No full textAbstractObjectiveCancer affects the head and neck region frequently and leads to significant morbidity and mortality. Oncolytic viral therapy has the potential to make a big impact in cancers that affect the head and neck. We intend to review the current state of oncolytic viruses in the treatment of cancers that affect the head and neck region.MethodData sources are from National clinical trials database, literature, and current research.ResultsThere are many past and active trials for oncolytic viruses that show promise for treating cancers of the head and neck. The first oncolytic virus was approved by the FDA October 2015 (T-VEC, Amgen) for the treatment of melanoma. Active translational research continues for this and many other oncolytic viruses.ConclusionThe evolving field of oncolytic viruses is impacting the treatment of head and neck cancer and further trials and agents are moving forward in the coming years
Magnetic resonance imaging characteristics of lesions relate to the difficulty of peripheral arterial endovascular procedures
No full textStudying technology use as social practice: the untapped potential of ethnography
No full textAbstract Information and communications technologies (ICTs) in healthcare are often introduced with expectations of higher-quality, more efficient, and safer care. Many fail to meet these expectations. We argue here that the well-documented failures of ICTs in healthcare are partly attributable to the philosophical foundations of much health informatics research. Positivistic assumptions underpinning the design, implementation and evaluation of ICTs (in particular the notion that technology X has an impact which can be measured and reproduced in new settings), and the deterministic experimental and quasi-experimental study designs which follow from these assumptions, have inherent limitations when ICTs are part of complex social practices involving multiple human actors. We suggest that while experimental and quasi-experimental studies have an important place in health informatics research overall, ethnography is the preferred methodological approach for studying ICTs introduced into complex social systems. But for ethnographic approaches to be accepted and used to their full potential, many in the health informatics community will need to revisit their philosophical assumptions about what counts as research rigor.</p
