Making the Connection: Using Concept Mapping to Bring the Basic Sciences to the Diagnosis.

Although medical education has historically emphasized the role and importance of basic science in clinical reasoning, educators have struggled to teach basic science to optimize its use for students. Concept mapping helps students develop relationships between basic and clinical science, which can enhance understanding of the material. Educators at the University of New England College of Osteopathic Medicine developed a weekly concept-mapping activity connecting biomedical principles with clinical signs, symptoms, and laboratory values from a comprehensive clinical case. This activity elicits cross-disciplinary discussion, illustrates content integration by the students, and enhances faculty collaboration across disciplines.

Advancing Nutrition Education, Training, and Research for Medical Students, Residents, Fellows, Attending Physicians, and Other Clinicians: Building Competencies and Interdisciplinary Coordination.

Nutrition plays an important role in health promotion and disease prevention and treatment across the lifespan. Physicians and other healthcare professionals are expected to counsel patients about nutrition, but recent surveys report minimal to no improvements in medical nutrition education in US medical schools. A workshop sponsored by the National Heart, Lung, and Blood Institute addressed this gap in knowledge by convening experts in clinical and academic health professional schools. Representatives from the National Board of Medical Examiners, the Accreditation Council for Graduate Medical Education, the Liaison Committee on Medical Education, and the American Society for Nutrition provided relevant presentations. Reported is an overview of lessons learned from nutrition education efforts in medical schools and health professional schools including interprofessional domains and competency-based nutrition education. Proposed is a framework for coordinating activities of various entities using a public-private partnership platform. Recommendations for nutrition research and accreditation are provided.

Physicians' Religious Characteristics and Their Perceptions of the Psychological Impact of Patient Prayer and Beliefs at the End of Life: A National Survey.

BACKGROUND:: Physicians who are more religious or spiritual may report more positive perceptions regarding the link between religious beliefs/practices and patients' psychological well-being. METHODS:: We conducted a secondary data analysis of a 2010 national survey of US physicians from various specialties (n = 1156). Respondents answered whether the following patient behaviors had a positive or negative effect on the psychological well-being of patients at the end of life: (1) praying frequently, (2) believing in divine judgment, and (3) expecting a miraculous healing. We also asked respondents how comfortable they are talking with patients about death. RESULTS:: Eighty-five percent of physicians believed that patients' prayer has a positive psychological impact, 51% thought that patients' belief in divine judgment has a positive psychological impact, and only 17% of physicians thought the same with patients' expectation of a miraculous healing. Opinions varied based on physicians' religious and spiritual characteristics. Furthermore, 52% of US physicians appear to feel very comfortable discussing death with patients, although end-of-life specialists, Hindu physicians, and spiritual physicians were more likely to report feeling very comfortable discussing death (adjusted odds ratio range: 1.82-3.00). CONCLUSION:: US physicians hold divided perceptions of the psychological impact of patients' religious beliefs/practices at the end of life, although they more are likely to believe that frequent prayer has a positive psychological impact for patients. Formal training in spiritual care may significantly improve the number of religion/spirituality conversations with patients at the end of life and help doctors understand and engage patients' religious practices and beliefs.

Rapid automated materials synthesis instrument: exploring the composition and heat-treatment of nanoprecursors toward low temperature red phosphors.

We report on the commissioning experimental run of the rapid automated materials synthesis instrument (RAMSI), a combinatorial robot designed to manufacture, clean, and print libraries of nanocrystal precursor solid compositions. The first stage of RAMSI, parallel synthesis, uses a fully automated high throughput continuous hydrothermal (HiTCH) flow reactor for automatic metal salt precursor mixing, hydrothermal flow reaction, and sample slurry collection. The second stage of RAMSI provides integrated automated cleanup, and the third section is a ceramic printing function. Nanocrystal precursor solid ceramics were synthesized from precursor solutions and collected into 50 mL centrifuge tubes where they were cleaned by multiple centrifugation and redispersion cycles (monitored by intelligent scanning turbidimetry) and printed with an automated pipette. Eight unique compositions of a model phosphor library comprising pure nano-Y(OH)(3) and Eu(3+) doped-yttrium hydroxide, Y(OH)(3):Eu(3+) nanocrystal precursor solid were synthesized (with 2 centrifuge tubes' worth collected per composition), processed, and printed in duplicate as 75, 100, and 125 microL dots in a 21.6 ks (6 h) experiment (note: the actual time for synthesis of each sample tube was only 12 min so up to 60 compositions could easily be synthesized in 12 h if one centrifuge tube per composition was collected instead). The Y(OH)(3):Eu(3+) samples were manually placed in a furnace and heat-treated in air for 14.4 ks (4 h) in the temperature range 200-1200 at 100 degrees C intervals (giving a total of 84 samples plus one as-prepared pure Y(OH)(3) sample). The as-prepared and heat-treated ceramic samples were affixed to 4 mm wide hemispherical wells in a custom-made aluminum well-plate and analyzed using a fluorescence spectrometer. When the library was illuminated with a 254 nm light source (and digitally imaged and analyzed), the 3 mol % Eu(3+) sample heat-treated at 1200 degrees C gave the most intense fluorescence (major red peak at 612 nm); however, an identical nanocrystal precursor heat-treated at only 500 degrees C (identified as Y(2)O(3):Eu(3+) after heat treatment) was the brightest phosphor under illumination of the samples heat-treated at or below 1000 degrees C.
