question:
The purpose of this study was to determine whether four types of professionalism deficiencies in medical students identified during a first-year course on doctor-patient relationships might predict poor performance in third-year clerkships.', 'Preceptors identified students who had deficiencies in interviewing patients: extreme shyness, poor process skills, paternalism, or a negative attitude toward interviewing. Deficient students were matched by academic ability to a control group. Performance on third-year clerkships was compared.', 'Students with paternalistic behavior or negative attitudes had significantly lower third-year grades.
answer:
Do professionalism deficiencies in a first-quarter doctor-patient relationship course predict poor clinical performance in medical school?


question:
Cognitive changes after ischemic stroke are often overlooked, particularly acutely and in patients with mild or transient deficits. We assessed patients with transient ischemic attack (TIA)/minor stroke with serial cognitive screening tests. We tested the hypothesis that mild acute deficits are transient and improve after TIA/minor stroke.', 'Patients with acute TIA/minor ischemic stroke, without a history of cognitive impairment, presenting with a National Institute of Health Stroke Scale score ≤3 were assessed <72 hours of onset. Patients were administered the Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA) at days 1, 7, 30, and 90. Cognitive impairment was defined as MoCA <26 and MMSE ≤26.', 'One hundred patients with a median (interquartile range) National Institute of Health Stroke Scale score of 1 (2) and median age of 68 (20) years were included. Baseline median MoCA score (26 [4]) was lower than the MMSE (29 [2]; P<0.0001). Cognitive impairment was detected in 54 of 100 patients (54%) with MoCA and 16 of 100 (16%; P=0.001) with MMSE. MoCA scores improved at day 7 (27 [5]), day 30 (28 [2]), and day 90 (28 [2]; P<0.0001). Resolution of cognitive deficits was because of resolution of recall deficits.
answer:
Do serial montreal cognitive assessments demonstrate reversible cognitive impairment in patients with acute transient ischemic attack and minor stroke?


question:
A transgenic mouse model has revealed parameters of the angiogenic switch during multistep tumorigenesis of pancreatic islets, and demonstrated efficacy of antiangiogenic therapies. Pericytes have been revealed as functionally important for tumor neovasculature, using kinase inhibitors targeting their platelet-derived growth factor receptors (PDGFRs). Additionally, vascular endothelial growth factor receptor (VEGFR) inhibitors and metronomic chemotherapy show modest benefit against early- but not late-stage disease.', 'Seeking to improve efficacy against otherwise intractable end-stage pancreatic islet tumors, two receptor tyrosine kinase inhibitors, imatinib and SU11248, were used to disrupt PDGFR-mediated pericyte support of tumor endothelial cells in concert with maximum-tolerated dose (MTD) or metronomic chemotherapy and/or VEGFR inhibition.', 'Imatinib, despite equivocal efficacy as monotherapy, reduced pericyte coverage of tumor vessels and enhanced efficacy in combination with metronomic chemotherapy or VEGFR inhibition. A regimen involving all three was even better. MTD using cyclophosphamide caused transitory regression, but then rapid regrowth, in contrast to metronomic cyclophosphamide plus imatinib, which produced stable disease. The MTD regimen elicited apoptosis of tumor cells but not endothelial cells, whereas the other regimens increased endothelial cell apoptosis concordant with efficacy. A "chemo-switch" protocol, involving sequential MTD and then metronomic chemotherapy, overlaid with multitargeted inhibition of PDGFR and VEGFR, gave complete responses and unprecedented survival advantage in this model.
answer:

Is a multitargeted , metronomic , and maximum-tolerated dose `` chemo-switch '' regimen antiangiogenic , producing objective responses and survival benefit in a mouse model of cancer?
