A Review of Continuous Quality Improvement Processes at Ten Medical Schools.

The Liaison Committee on Medical Education now expects all allopathic medical schools to develop and adhere to a documentable continuous quality improvement (CQI) process. Medical schools must consider how to establish a defensible process that monitors compliance with accreditation standards between site visits. The purpose of this descriptive study is to detail how ten schools in the Association of American Medical Colleges' (AAMC) Southern Group on Educational Affairs (SGEA) CQI Special Interest Group (SIG) are tackling practical issues of CQI development including establishing a CQI office, designating faculty and staff, charging a CQI committee, choosing software for data management, if schools are choosing formalized CQI models, and other considerations.

Epigenetic analysis of neurocognitive development at 1 year of age in a community-based pregnancy cohort.

Multiple studies show that molecular genetic changes and epigenetic modifications affect the risk of cognitive disability or impairment. However, the role of epigenetic variation in cognitive development of neurotypical young children remains largely unknown. Using data from a prospective, community-based study of mother-infant pairs, we investigated the association of DNA methylation patterns in neonatal umbilical cord blood with cognitive and language development at 1 year of age.

Comparison between southern blots and qPCR analysis of leukocyte telomere length in the health ABC study.

Only a few studies, primarily limited to small samples, have examined the relationship between leukocyte telomere length (LTL) data generated by Southern blots, expressed in kilobases, versus quantitative PCR data, expressed in the telomere product/a single gene product (T/S). In the present study, we compared LTL data generated by the two methods in 681 elderly participants (50% African Americans, 50% of European origin, 49.2% women, mean age 73.

Naturally occurring dominant resistance mutations to hepatitis C virus protease and polymerase inhibitors in treatment-naïve patients.

Unlabelled: Resistance mutations to hepatitis C virus (HCV) nonstructural protein 3 (NS3) protease inhibitors in <1% of the viral quasispecies may still allow >1000-fold viral load reductions upon treatment, consistent with their reported reduced replicative fitness in vitro. Recently, however, an R155K protease mutation was reported as the dominant quasispecies in a treatment-naïve individual, raising concerns about possible full drug resistance. To investigate the prevalence of dominant resistance mutations against specifically targeted antiviral therapy for HCV (STAT-C) in the population, we analyzed HCV genome sequences from 507 treatment-naïve patients infected with HCV genotype 1 from the United States, Germany, and Switzerland.

Preliminary findings: 25(OH)D levels and PTH are indicators of rapid bone accrual in pubertal children.

Objective: The objective of this study was to evaluate the role of serum levels of 25(OH)D and PTH on the accumulation of whole body bone mass in a cohort of children.

Methods: This was a longitudinal study (1.98 +/- 0.

Hepatitis C hypervariable region 1: association of reduced selection pressure in african americans with treatment failure.

In a prospective therapeutic trial, features of the hepatitis C quasispecies were investigated as possible markers of therapeutic response. Individuals chronically infected with hepatitis C genotype 1 received antiviral therapy consisting of alpha-interferon plus ribavirin. The study targeted the most rapidly evolving segment of the viral genome, hypervariable region 1 within the envelope-2 gene.
