PURPOSE

The demand for faculty development is ongoing, and many medical schools will need to expand their pool of faculty developers to include physicians and scientists whose primary expertise is not education. Insight into what motivates occasional faculty developers can guide recruitment and retention strategies. This study was designed to understand the motivations of faculty developers who occasionally (one to three times each year) lead faculty development workshops.

METHOD

Qualitative data were collected in March and April 2012 from interviews with faculty developers who occasionally taught workshops from 2007 to 2012 in the University of California, San Francisco, School of Medicine's faculty development program. The interviews were audiotaped and transcribed. The authors thematically analyzed the transcripts using a general inductive approach and developed codes sensitized by motivation theories.

RESULTS

The authors interviewed 29/30 (97%) occasional faculty developers and identified five themes: mastery (desire to learn and develop professionally), relatedness (enjoyment of working with and learning from others), duty (sense of obligation to give back and be a good academic citizen), purpose (commitment to improving local teaching and ultimately patient care), and satisfaction (fun and enjoyment).

CONCLUSIONS

Four of the themes the authors found are well addressed in motivation theory literature: mastery, relatedness, duty, and purpose. Whereas these four are motivators for occasional faculty developers, it is the fifth theme-satisfaction-that the authors feel is foundational and links the others together. Armed with this understanding, individuals leading faculty development programs can develop strategies to recruit and retain occasional faculty developers.

Evidence-based medicine (EBM) skills, although taught in medical schools around the world, are not optimally practiced in clinical environments because of multiple barriers, including learners' difficulty transferring EBM skills learned in the classroom to clinical practice. This lack of skill transfer may be partially due to the design of EBM training. To facilitate the transfer of EBM skills from the classroom to clinical practice, the authors explore one instructional approach, called the Four Component Instructional Design (4C/ID) model, to guide the design of EBM training. On the basis of current cognitive psychology, including cognitive load theory, the premise of the 4C/ID model is that complex skills training, such as EBM training, should include four components: learning tasks, supportive information, procedural information, and part-task practice. The combination of these four components can inform the creation of complex skills training that is designed to avoid overloading learners' cognitive abilities; to facilitate the integration of the knowledge, skills, and attitudes needed to execute a complex task; and to increase the transfer of knowledge to new situations. The authors begin by introducing the 4C/ID model and describing the benefits of its four components to guide the design of EBM training. They include illustrative examples of educational practices that are consistent with each component and that can be applied to teaching EBM. They conclude by suggesting that medical educators consider adopting the 4C/ID model to design, modify, and/or implement EBM training in classroom and clinical settings.

Head and neck lymphatic malformations can create airway management challenges requiring tracheotomy. Sirolimus, an inhibitor of mammalian target of rapamycin (mTOR), may inhibit growth of lymphatic malformations. We describe two patients born with large lymphatic malformations with improved airway symptoms following sirolimus therapy. Patient #1 underwent tracheotomy and multi-modal therapy including sirolimus with reduction in airway involvement but regrowth after discontinuation of sirolimus. Patient #2 also experienced a significant response to sirolimus allowing for extubation and discharge without tracheotomy. Early initiation of sirolimus therapy should be considered as a means to avoid tracheotomy in complex head and neck lymphatic malformations.

Neuropathic pain is a chronic debilitating disease that results from nerve damage, persists long after the injury has subsided, and is characterized by spontaneous pain and mechanical hypersensitivity. Although loss of inhibitory tone in the dorsal horn of the spinal cord is a major contributor to neuropathic pain, the molecular and cellular mechanisms underlying this disinhibition are unclear. Here, we combined pharmacogenetic activation and selective ablation approaches in mice to define the contribution of spinal cord parvalbumin (PV)-expressing inhibitory interneurons in naive and neuropathic pain conditions. Ablating PV neurons in naive mice produce neuropathic pain-like mechanical allodynia via disinhibition of PKCγ excitatory interneurons. Conversely, activating PV neurons in nerve-injured mice alleviates mechanical hypersensitivity. These findings indicate that PV interneurons are modality-specific filters that gate mechanical but not thermal inputs to the dorsal horn and that increasing PV interneuron activity can ameliorate the mechanical hypersensitivity that develops following nerve injury.

CONTEXT

A single measurement of 25-hydroxyvitamin D (25 [OH] D) may not accurately reflect long-term vitamin D status. Little is known about change in 25(OH)D levels over time, particularly among blacks.

OBJECTIVE

The objective of the study was to determine the longitudinal changes in 25(OH)D levels among Atherosclerosis Risk in Communities (ARIC) study participants.

DESIGN

This was a longitudinal study.

SETTING

The study was conducted in the general community.

PARTICIPANTS

A total of 9890 white and 3222 black participants at visit 2 (1990-1992), 888 whites and 876 blacks at visit 3 (1993-1994), and 472 blacks at the brain visit (2004-2006) participated in the study.

MAIN OUTCOME MEASURE

The 25(OH)D levels were measured, and regression models were used to assess the associations between clinical factors and longitudinal changes in 25(OH)D.

RESULTS

Vitamin D deficiency (50 nmol/L [20 ng/mL]) was seen in 23% and 25% of whites at visits 2 and 3, and in 61%, 70%, and 47% of blacks at visits 2, 3, and the brain visit, respectively. The 25(OH)D levels were correlated between visits 2 and 3 (3 y interval) among whites (r = 0.73) and blacks (r = 0.66). Among blacks, the correlation between visit 2 and the brain visit (14 y interval) was 0.33. Overall, increases in 25(OH)D levels over time was associated with male gender, use of vitamin D supplements, greater physical activity, and higher high-density lipoprotein-cholesterol (P .001). Decreases in 25(OH)D levels over time were associated with current smoking, higher body mass index, higher education, diabetes, and hypertension (all P .05).

CONCLUSIONS

Among US blacks and whites, 25(OH)D levels remained relatively stable over time. Certain modifiable lifestyle factors were associated with change in 25(OH)D levels over time.
