MRI Predictive Model's Utility in a Recruit Training Environment for Tibia Stress Fractures.

Objective: The purpose of the study was to assess the utility of Fredricson Magnetic Resonance Imaging Grading model in predicting return to duty in Marine recruits who sustain tibia stress fractures at Marine Corps Recruit Depot San Diego (MCRDSD).

Materials And Methods: A retrospective review of 106 tibia stress fractures in 82 Marine recruits was performed. A baseline Fredricson grade was assigned, based on magnetic resonance imaging (MRI) evaluation.

Evaluating ventricular function with B-type natriuretic peptide in obstetric patients.

Objective: To determine if a rapid serum assay for B-type natriuretic peptide (BNP) provides information regarding ventricular function in obstetric patients with acute dyspnea.

Study Design: A review of 17 charts for 15 patients was undertaken. Seven patients had preeclampsia, 3 had preterm labor treated with aggressive tocolysis, and 5 had underlying cardiac and/or pulmonary disease.

Clinical utility of aortic pulses and pressures calculated from applanated radial-artery pulses.

Brachial artery cuff blood pressures are but approximations of central aortic pressures. The actual pressures against which the left ventricle must pump would be useful clinical information if obtained noninvasively. Our aim was to determine the clinical utility of aortic pulses and pressures calculated from noninvasively obtained radial-artery pulses.
