TL;DR: This compilation and analysis of promoters with known transcriptional start points for E. coli genes should be useful for studies of promoter structure and function and for programs which identify potential promoter sequences.
Abstract: We have compiled and analyzed 263 promoters with known transcriptional start points for E. coli genes. Promoter elements (-35 hexamer, -10 hexamer, and spacing between these regions) were aligned by a program which selects the arrangement consistent with the start point and statistically most homologous to a reference list of promoters. The initial reference list was that of Hawley and McClure (Nucl. Acids Res. 11, 2237-2255, 1983). Alignment of the complete list was used for reference until successive analyses did not alter the structure of the list. In the final compilation, all bases in the -35 (TTGACA) and -10 (TATAAT) hexamers were highly conserved, 92% of promoters had inter-region spacing of 17 +/- 1 bp, and 75% of the uniquely defined start points initiated 7 +/- 1 bases downstream of the -10 region. The consensus sequence of promoters with inter-region spacing of 16, 17 or 18 bp did not differ. This compilation and analysis should be useful for studies of promoter structure and function and for programs which identify potential promoter sequences.

TL;DR: Broadly defined CME interventions using practice-enabling or reinforcing strategies consistently improve physician performance and, in some instances, health care outcomes.
Abstract: Objective. —To assess the impact of diverse continuing medical education (CME) interventions on physician performance and health care outcomes. Data Sources. —Usingcontinuing medical educationand related phrases, we performed regular searches of the indexed literature (MEDLINE, Social Science Index, the National Technical Information Service, and Educational Research Information Clearinghouse) from 1975 through 1991. In addition, for these years, we used manual searches, key informants, and requests to authors to locate other indexed articles and the nonindexed literature of adult and continuing professional education. Study Selection. —From the resulting database we selected studies that met the following criteria: randomized controlled trials; educational programs, activities, or other interventions; studies that included 50% or more physicians; follow-up assessments of at least 75% of study subjects; and objective assessments of either physician performance or health care outcomes. Data Extraction. —Studies were reviewed for data related to physician specialty and setting. Continuing medical education interventions were classified by their mode(s) of activity as being predisposing, enabling, or facilitating. Using the statistical tests supplied by the original investigators, physician performance outcomes and patient outcomes were classified as positive, negative, or inconclusive. Data Synthesis. —We located 777 CME studies, of which 50 met all criteria. Thirty-two of these analyzed physician performance; seven evaluated patient outcomes; 11 examined both measures. The majority of the 43 studies of physician performance showed positive results in some important measures of resource utilization, counseling strategies, and preventive medicine. Of the 18 studies of health care outcomes, eight demonstrated positive changes in patients' health care outcomes. Conclusion. —Broadly defined CME interventions using practice-enabling or reinforcing strategies consistently improve physician performance and, in some instances, health care outcomes.

TL;DR: Even short durations of an intraoperative mean arterial pressure less than 55 mmHg are associated with AKI and myocardial injury, and Randomized trials are required to determine whether outcomes improve with interventions that maintain an intraoper MAP of at least 55mmHg.
Abstract: Background:Intraoperative hypotension may contribute to postoperative acute kidney injury (AKI) and myocardial injury, but what blood pressures are unsafe is unclear. The authors evaluated the association between the intraoperative mean arterial pressure (MAP) and the risk of AKI and myocardial inju

TL;DR: The rationale and development of the COPM, an outcome measure designed for use by occupational therapists to assess client outcomes in the areas of self-care, productivity and leisure, are described.
Abstract: The Canadian Association of Occupational Therapists, in collaboration with Health and Welfare Canada have developed and published a conceptual model for occupational therapy, the Occupational Performance model. This paper describes the development of an outcome measure, The Canadian Occupational Performance Measure (COPM), which is designed to be used with these guidelines for client-centred clinical practice. The COPM is an outcome measure designed for use by occupational therapists to assess client outcomes in the areas of self-care, productivity and leisure. Using a semi-structured interview, the COPM is a five step process which measures individual, client-identified problem areas in daily function. Two scores, for performance and satisfaction with performance are obtained. This paper describes the rationale and development of the COPM as wellas information about its use for therapists.
