Endothelial stress products and coagulation markers in patients with multiple myeloma treated with lenalidomide plus dexamethasone: an observational study.

In this prospective study of patients with relapsed or relapsed and refractory multiple myeloma (MM) treated with lenalidomide and dexamethasone, relationships between markers of endothelial stress and drug administration and incidence of venous thromboembolism (VTE) were assessed. Of 33 enrolled patients, laboratory and treatment data were available for 32 patients. Of these, 23 received pulsed dexamethasone (40 mg/day on days 1-4, 9-12 and 17-21 of each 28-day cycle) and 9 received weekly dexamethasone (40 mg/day on days 1, 8, 15 and 21 of each cycle). The overall incidence of VTE was 9%. A decreasing trend in markers values was observed with intercellular adhesion molecule (P = 0·05), fibrinogen (P = 0·008), plasminogen activator inhibitor-1 (P < 0·001), homocysteine (P = 0·002) and P-selectin (P < 0·001) during therapy. Compared with weekly dexamethasone, pulsed dexamethasone was associated with significantly greater variation in mean adjusted relative values of fibrinogen, P-selectin and vascular endothelial growth factor (P < 0·001 for all comparisons), although there was no apparent association with VTE incidence. Lenalidomide plus dexamethasone affects endothelial stress marker levels in patients with advanced MM. The higher variation seen with pulsed dexamethasone suggests greater endothelial stress with this approach.

The ObGyn clerkship: are students denied the opportunity to provide patient care and what is the role of gender?

OBJECTIVE: We sought to study the frequency, and reasons that third-year medical students on an ObGyn clerkship are denied the opportunity to be involved in patient care. METHODS: Students from four hospitals affiliated with the University of Connecticut Medical School completed an anonymous postclerkship survey. RESULTS: Among the 157 students studied (66 males and 91 females), 51% (n = 80) were denied the opportunity to participate in a gynecologic examination and 47% (n = 73) were denied the opportunity for routine ObGyn care by patients. Among these students, 55% (n = 44) and 38% (n = 28) stated that being male was the reason they were excluded from gynecologic and routine care, respectively. Of the 80 students who were denied involvement in a gynecologic examination, 81% (n = 65) were denied involvement by clinic patients. Of the 44 males who stated they were denied the opportunity to be involved in a gynecologic examination due to their gender, 89% (n = 39) were refused by clinic patients. Compared with female students, male students are statistically more likely to be denied the opportunity to be involved in gynecologic examinations (RR = 1.69 [1.24-2.29]), especially by clinic patients (RR = 2.07 [1.41-3.03]). CONCLUSION: A significant number of students were denied the opportunity to be involved in ObGyn care experiences. More frequently male students were denied involvement in care, with a higher incidence among clinic patients. We hypothesize that being denied involvement provides a negative perception of the ObGyn specialty, especially to male students, possibly affecting their decision to choose ObGyn training. PRECIS: A significant number of medical students, particularly males, were denied involvement in patient care, primarily by clinic patients, during the ObGyn clerkships.
