Patient Education Using the Cognitive Apprenticeship Model: A Study for Rehabilitation Specialists

Quality patient education has long been a concern for both patients and health care providers. While many clinicians support the importance of patient education, it is not known which theoretical education model supports best practice. The purpose of this study is to determine the effectiveness of the Cognitive Apprenticeship Model (CA) when compared to traditional patient education. There were 34 individuals receiving therapy who volunteered to be in a treatment group that received patient education using the CA model. There were 24 individuals who were assigned to a control group who received traditional patient education. While not all of the outcomes measured in this study showed significance as anticipated, several key outcomes showed statistical significances between the treatment group and the control group. Thus, supporting the hypotheses that the use of CA in patient education would improve patient outcomes, specifically in 1) Patient Specific function analysis outcomes questionnaire. 2) Pre-test vs post-test scores on patient’s knowledge about their condition and how to manage it. 3) Patient continued use of a home exercise program post discharge. This is important in that the use of CA as a theoretical educational model for patient education resulted in better patient compliance with home exercises four weeks after discharge from skilled therapy. Greater differences in pre-test vs post-test knowledge scores, indicating patient empowerment and greater understanding of the importance of their continued follow-up to care for themselves. This supports the concept that the teaching methods used in how patients are taught is relevant and equally important to what they are taught. As healthcare providers learn to become better teachers of their patients, engaging in the use of theoretically grounded teaching methods, patient outcomes are likely to improve. This results in best practice methods for the delivery of healthcare and improvements in patient outcomes

Tissue Cytokine Responses in Canine Visceral Leishmaniasis

To elucidate the local tissue cytokine response of dogs infected with Leishmania chagasi, cytokine mRNA levels were measured in bone marrow aspirates from 27 naturally infected dogs from Brazil and were compared with those from 5 uninfected control animals. Interferon-γ mRNA accumulation was enhanced in infected dogs and was positively correlated with humoral (IgG1) but not with lymphoproliferative responses to Leishmania antigen in infected dogs. Increased accumulation of mRNA for interleukin (IL)4, IL-10, and IL-18 was not observed in infected dogs, and mRNA for these cytokines did not correlate with antibody or proliferative responses. However, infected dogs with detectable IL-4 mRNA had significantly more severe symptoms. IL-13 mRNA was not detectable in either control or infected dogs. These data suggest that clinical symptoms are not due to a deficiency in interferon-γ production. However, in contrast to its role in human visceral leishmaniasis, IL-10 may not play a key immunosuppressive role in dogs

Gravitational lens magnification by Abell 1689: Distortion of the background galaxy luminosity function

Gravitational lensing magnifies the luminosity of galaxies behind the lens. We use this effect to constrain the total mass in the cluster Abell 1689 by comparing the lensed luminosities of background galaxies with the luminosity function of an undistorted field. Since galaxies are assumed to be a random sampling of luminosity space, this method is not limited by clustering noise. We use photometric redshift information to estimate galaxy distance and intrinsic luminosity. Knowing the redshift distribution of the background population allows us to lift the mass/background degeneracy common to lensing analysis. In this paper we use 9 filters observed over 12 hours with the Calar Alto 3.5m telescope to determine the redshifts of 1000 galaxies in the field of Abell 1689. Using a complete sample of 151 background galaxies we measure the cluster mass profile. We find that the total projected mass interior to 0.25h^(-1)Mpc is (0.48 +/- 0.16) * 10^(15)h^(-1) solar masses, where our error budget includes uncertainties from the photometric redshift determination, the uncertainty in the off-set calibration and finite sampling. This result is in good agreement with that found by number count and shear-based methods and provides a new and independent method to determine cluster masses.Comment: 13 pages, 10 figures.

Orbit equivalence rigidity for ergodic actions of the mapping class group

We establish orbit equivalence rigidity for any ergodic, essentially free and measure-preserving action on a standard Borel space with a finite positive measure of the mapping class group for a compact orientable surface with higher complexity. We prove similar rigidity results for a finite direct product of mapping class groups as well.Comment: 11 pages, title changed, a part of contents remove

Promoting REU participation from students in underrepresented groups

Research experiences for undergraduates (REUs) are an important component of undergraduate education. However, at the 2012 Trends in Undergraduate Research in the Mathematical Sciences conference, questions were raised about why many REU programs see few applications from students that are members of underrepresented groups. We examine the benefits of REUs and factors preventing or promoting participation in REUs
