Emotional intelligence and selection to administrative chief residency.

OBJECTIVE: The authors sought to determine whether emotional intelligence, as measured by the BarOn emotional quotient inventory (EQ-i), is associated with selection to administrative chief resident. METHOD: Authors invited senior-year residents at the University of Texas Health Science Center at Houston to participate in an observational cross-sectional study using the BarOn EQ-i. In October 2009 they sent an invitation e-mail to 66 senior residents, with a reminder e-mail 1 month later. The study was designed to detect a 15-point difference in EQ-i scores with 80% power. RESULTS: Of the 66 invited residents, 69.6% participated in the study. Average total EQ-I score was 104.9. Among senior-year residents, there were no statistically significant differences in EQ-i scores between administrative chief residents (at 109) and non-administrative chief residents (at 103.2). CONCLUSION: Administrative chief residents do not demonstrate higher Emotional Intelligence, as measured by the EQ-i, than other senior-year residents.

Determination of cyclin D1 and CD20 mRNA levels by real-time quantitative RT-PCR from archival tissue sections of mantle cell lymphoma and other non-Hodgkin's lymphomas.

Cyclin D1 overexpression is a valuable marker for the diagnosis of mantle cell lymphoma (MCL). We used a real-time quantitative reverse transcription-polymerase chain reaction (qRT-PCR) method to quantify levels of cyclin D1, CD20, and cyclophilin A mRNA in manually microdissected, paraffin-embedded tissue sections using an ABI 7700 qRT-PCR system. The study group included 21 cases of MCL and 37 cases of other types of B-cell non-Hodgkin's lymphoma. Cyclin D1 mRNA copy number was normalized to CD20 and cyclophilin A mRNA and evaluated statistically by analysis of variance. The relative cyclin D1 levels were similar whether normalized to CD20 or cyclophilin A, indicating that CD20 levels are stable and can be used as a B-cell-specific normalizer. Statistically significant differences were found in the median levels of cyclin D1 mRNA (expressed as % CD20 mRNA) among cases of MCL (87.6), small lymphocytic lymphoma (9.9), follicular lymphoma (2.4), diffuse large B-cell lymphoma (5.9), marginal zone B-cell lymphoma (39.8), and Burkitt lymphoma (7.1) (P < 0.05). We conclude that qRT-PCR can be used to quantify cyclin D1 mRNA levels in archival tissue sections. Normalization of cyclin D1 to a B-cell-specific marker more accurately reflects overexpression by MCL than other methods that normalize using constitutively expressed mRNA species.
