We hypothesized that serum cystatin C can be a more predictable marker of arterial stiffness than serum creatinine and creatinine-based glomerular filtration rate (GFR). The aim of this study is to evaluate whether serum cystatin C is related to arterial stiffness independently of serum creatinine in subjects for whom serum creatinine is normal. A total of 2,018 individuals (1,120 males, 898 females) were enrolled. Mean brachial-ankle pulse wave velocity (baPWV) was used as a marker of arterial stiffness and sex-specific analysis was performed. A positive relationship between baPWV and serum cystatin C (Y=1109.0548+329.9102X, r2=0.056, p<0.001) was found in males. Stepwise multivariate regression analysis in males showed that age, waist circumference, heart rate, cystatin C level, triglyceride level, and fasting glucose were independent contributors to baPWV. In females, a positive relationship between baPWV and serum cystatin C (Y=1035.7828+402.2970X, r2=0.090, p<0.001) was found. Stepwise multivariate regression analysis showed that age, heart rate, cystatin C level, fasting glucose and insulin level were independent contributors to baPWV. Age, heart rate, fasting glucose and serum cystatin C were the significant variables in both genders that contributed to baPWV. In conclusion, this study confirmed that serum cystatin C was related to pulse wave velocity even in subjects with normal serum creatinine. This finding suggested that cystatin C could be a more predictable marker of arterial stiffness than serum creatinine and creatinine-based GFR.

Ex Output:
Serum Cystatin C Is Related to Pulse Wave Velocity Even in Subjects with Normal Serum Creatinine

CONTEXT Certification by an American Board of Medical Specialties (ABMS) member board is emerging as a measure of physician quality.
OBJECTIVE To identify demographic and educational factors associated with ABMS member board certification of US medical school graduates.
DESIGN, SETTING, AND PARTICIPANTS Retrospective study of a national cohort of 1997-2000 US medical school graduates, grouped by specialty choice at graduation and followed up through March 2, 2009. In separate multivariable logistic regression models for each specialty category, factors associated with ABMS member board certification were identified.
MAIN OUTCOME MEASURE ABMS member board certification.
RESULTS Of 42,440 graduates in the study sample, 37,054 (87.3%) were board certified. Graduates in all specialty categories with first-attempt passing scores in the highest tertile (vs first-attempt failing scores) on US Medical Licensing Examination Step 2 Clinical Knowledge were more likely to be board certified; adjusted odds ratios (AORs) varied by specialty category, with the lowest odds for emergency medicine (87.4% vs 73.6%; AOR, 1.82; 95% CI, 1.03-3.20) and highest odds for radiology (98.1% vs 74.9%; AOR, 13.19; 95% CI, 5.55-31.32). In each specialty category except family medicine, graduates self-identified as underrepresented racial/ethnic minorities (vs white) were less likely to be board certified, ranging from 83.5% vs 95.6% in the pediatrics category (AOR, 0.44; 95% CI, 0.33-0.58) to 71.5% vs 83.7% in the other nongeneralist specialties category (AOR, 0.79; 95% CI, 0.64-0.96). With each $50,000 unit increase in debt (vs no debt), graduates choosing obstetrics/gynecology were less likely to be board certified (AOR, 0.89; 95% CI, 0.83-0.96), and graduates choosing family medicine were more likely to be board certified (AOR, 1.13; 95% CI, 1.01-1.26).
CONCLUSION Demographic and educational factors were associated with board certification among US medical school graduates in every specialty category examined; findings varied among specialty categories.

Ex Output:
Factors associated with American Board of Medical Specialties member board certification among US medical school graduates.

Ex Input:
INO80 is an evolutionarily conserved, ATP-dependent chromatin-remodeling enzyme that plays roles in transcription, DNA repair, and replication. Here, we show that yeast INO80 facilitates these diverse processes at least in part by controlling genome-wide distribution of the histone variant H2A.Z. In the absence of INO80, H2A.Z nucleosomes are mislocalized, and H2A.Z levels at promoters show reduced responsiveness to transcriptional changes, suggesting that INO80 controls H2A.Z dynamics. Additionally, we demonstrate that INO80 has a histone-exchange activity in which the enzyme can replace nucleosomal H2A.Z/H2B with free H2A/H2B dimers. Genetic interactions between ino80 and htz1 support a model in which INO80 catalyzes the removal of unacetylated H2A.Z from chromatin as a mechanism to promote genome stability.
