A Qualitative Analysis of Coronary Heart Disease Patients’ Views of Dietary Adherence and of Web-Based and Mobile-Based Nutrition Tools

Purpose: Dietary adherence can be challenging for patients with coronary heart disease (CHD), as they may require multiple dietary changes. Choosing appropriate food items may be difficult or take extensive amounts of time without the aid of technology. The objective of this project was to (1) examine the dietary challenges faced by patients with CHD, (2) examine methods of coping with dietary challenges, (3) explore the feasibility of a web-based food decision support system, and (4) explore the feasibility of a mobile-based food decision support system. Methods: Food for the Heart (FFH), a website-based food decision support system, and Mobile Magic Lens (MML), a mobile-based system, were developed to aid in daily dietary choices. Three CHD patient focus groups were conducted and focused on CHD-associated dietary changes as well as the FFH and MML prototypes. A total of 20 CHD patients and 7 informal caregivers participated. Qualitative, content analysis was performed to find themes grounded in the responses. Results: Five predominant themes emerged: 1) decreasing carbohydrate intake and portion control are common dietary challenges, 2) clinician and social support makes dietary adherence easier, 3) FFH could make meal-planning and dietary adherence less complicated, 4) MML could save time and assist with healthy choices, and 5) additional features need to be added to make both tools more comprehensive. Conclusions: FFH and MML may be tools that CHD patients would value in making food choices and adhering to dietary recommendations, especially if additional features are added to assist patients with changes

GK-12: NSF Graduate Teaching Fellows in K-12 Education at the University of Maine

Eight districts in central Maine that comprise the Penobscot River Educational Partnership (PREP); four of them, including Maine Indian Education, partners in a current GK-12 project, have joined with the University of Maine to form Fellow-teacher teams to introduce K-12 students to experiments, field trips, and discussions in areas such as chemistry, climate change, marine sciences, molecular biology, geology, food sciences, and ecology. The program is: a) helping teachers and students reach the State of Maine\u27s legislatively-mandated standards for Science & Technology (the Maine Learning Results), b) strengthening Fellows\u27 communication and teaching skills, c) providing professional development for Teachers, d) enriching science for K-12 students, e) providing young male and female role models of SMET professionals to children in grades 3-11, and f) strengthening contacts between GK-12 science faculty and K-12 districts. The K-12 students are monitoring water chemistry and species diversity and abundance in cooperating federal wildlife refuges in areas near them. These shared monitoring activities link classes throughout the entire scope of the project. The spatially and temporally distributed data enables the teams to introduce interesting analyses and discussions across partner classes interacting through videoconferences. Each Fellow works intensively with two teachers in PREP and with a teacher from eastern Maine (Washington & Hancock Counties), western Maine (Madison), or southern Maine (Damariscotta, site of the University of Maine\u27s marine sciences laboratory). The power of Maine\u27s network of ATM classrooms, is being used to expand the Fellows\u27 role modeling and introduce Fellows to a variety of teaching styles. The broader impacts of the project include strengthened backgrounds in science and attendance at the Maine summer Science Camp for the cooperating teachers. The K-12 districts\u27 benefits include the enriched learning of their students and access to the equipment from microscopes to thermal cyclers that is necessary to meet the goals of the Learning Results, but which many districts lack. The University of Maine is benefiting from K-12 students who come to the University better prepared in science and is fulfilling its mission as a Land Grant/Sea Grant institution to serve both the state of Maine and the nation as a whole

The FIELDS Instrument Suite for Solar Probe Plus: Measuring the Coronal Plasma and Magnetic Field, Plasma Waves and Turbulence, and Radio Signatures of Solar Transients.

NASA's Solar Probe Plus (SPP) mission will make the first in situ measurements of the solar corona and the birthplace of the solar wind. The FIELDS instrument suite on SPP will make direct measurements of electric and magnetic fields, the properties of in situ plasma waves, electron density and temperature profiles, and interplanetary radio emissions, amongst other things. Here, we describe the scientific objectives targeted by the SPP/FIELDS instrument, the instrument design itself, and the instrument concept of operations and planned data products

Central effects of atropine upon aversive classical conditioning in rabbits

Rabbits were given classical discrimination conditioning with one of two tones followed by shock. In Experiment I, 40 rabbits were trained under saline, 10, 18 or 26 mg/kg atropine sulfate or 18 mg/kg methylatropine. Six rabbits in Experiment 2 were conditioned, then given further sessions with saline, and 18, 26 and 34 mg/kg atropine sulfate and methylatropine. In Experiment 3, 18 rabbits were conditioned and then given two extinction sessions under saline or 34 mg/kg atropine sulfate or methylatropine followed by extinction under saline. Chief findings were (a) atropine sulfate but not methylatropine disrupted acquisition and maintenance of conditioned eyeblinks, (b) neither drug affected unconditioned blinks, (c) fewer blinks occurred in extinction under atropine sulfate than under methylatropine or saline, (d) rabbits extinguished under atropine sulphate showed higher percentages of eyeblinks when tested without drug. Disruptions in performance of learned eyeblink responses appeared to be due to drug interference with central cholinergic transmission.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/46381/1/213_2004_Article_BF00406735.pd

Effects of shared medical appointments on quality of life and cost-effectiveness for patients with a chronic neuromuscular disease. Study protocol of a randomized controlled trial

Contains fulltext : 96862.pdf (publisher's version ) (Open Access)BACKGROUND: Shared medical appointments are a series of one-to-one doctor-patient contacts, in presence of a group of 6-10 fellow patients. This group visits substitute the annual control visits of patients with the neurologist. The same items attended to in a one-to-one appointment are addressed. The possible advantages of a shared medical appointment could be an added value to the present management of neuromuscular patients. The currently problem-focused one-to-one out-patient visits often leave little time for the patient's psychosocial needs, patient education, and patient empowerment. METHODS/DESIGN: A randomized, prospective controlled study (RCT) with a follow up of 6 months will be conducted to evaluate the clinical and cost-effectiveness of shared medical appointments compared to usual care for 300 neuromuscular patients and their partners at the Radboud University Nijmegen Medical Center. Every included patient will be randomly allocated to one of the two study arms. This study has been reviewed and approved by the medical ethics committee of the region Arnhem-Nijmegen, The Netherlands. The primary outcome measure is quality of life as measured by the EQ-5D, SF-36 and the Individualized neuromuscular Quality of Life Questionnaire. The primary analysis will be an intention-to-treat analysis on the area under the curve of the quality of life scores. A linear mixed model will be used with random factor group and fixed factors treatment, baseline score and type of neuromuscular disease. For the economic evaluation an incremental cost-effectiveness analysis will be conducted from a societal perspective, relating differences in costs to difference in health outcome. Results are expected in 2012. DISCUSSION: This study will be the first randomized controlled trial which evaluates the effect of shared medical appointments versus usual care for neuromuscular patients. This will enable to determine if there is additional value of shared medical appointments to the current therapeutical spectrum. When this study shows that group visits produce the alleged benefits, this may help to increase the acceptance of this innovative and creative way of using one of the most precious resources in health care more efficiently: time.

Computational Models of Classical Conditioning guest editors’ introduction

In the present special issue, the performance of current computational models of classical conditioning was evaluated under three requirements: (1) Models were to be tested against a list of previously agreed-upon phenomena; (2) the parameters were fixed across simulations; and (3) the simulations used to test the models had to be made available. These requirements resulted in three major products: (a) a list of fundamental classical-conditioning results for which there is a consensus about their reliability; (b) the necessary information to evaluate each of the models on the basis of its ordinal successes in accounting for the experimental data; and (c) a repository of computational models ready to generate simulations. We believe that the contents of this issue represent the 2012 state of the art in computational modeling of classical conditioning and provide a way to find promising avenues for future model development
