Perioperative statin therapy reduces mortality in normolipidemic patients undergoing cardiac surgery

ObjectiveStatins might have pleiotropic effects, independent of their ability to reduce lipid levels. Recent data have suggested that statins improve early survival and cardiovascular outcomes after coronary artery bypass graft surgery. The effectiveness of statin therapy in normolipidemic cardiac surgery patients is as yet unclear.MethodsWe evaluated 3056 consecutive patients who had undergone cardiac surgery between April 2004 and April 2009. Perioperative statin therapy was defined as continued treatment both before (≥ 6 months) and after the index surgery (included as a discharge medication). Hyperlipidemia (HL) was defined as a total cholesterol level greater than 200 mg/dL within 6 months before surgery. Four groups were analyzed: (1) statin-untreated normolipidemic (NL−, n = 1052); (2) statin-treated normolipidemic (NL+, n = 206); (3) statin-untreated hyperlipidemic (HL−, n = 638); and (4) statin-treated hyperlipidemic (HL+, n = 1160) patients. Adjusted hazard ratios accounted for the known preoperative cardiac risk factors. Mortality was ascertained by retrospective database review and the Social Security Death Index.ResultsThe mean follow-up was 2.2 years. The crude rate of 30-day mortality was 3.0% (32/1052), 0% (0/206), 8.0% (51/638), and 0.7% (8/1160) for the NL−, NL+, HL−, and HL+ groups, respectively. The overall all-cause crude mortality rate was 9.6% (101/1052), 3.9% (8/206), 17.2% (110/638), and 6.5% (75/1160) for the NL−, NL+, HL−, and HL+ groups, respectively. Statin therapy for NL patients undergoing cardiac surgery independently reduced the overall all-cause mortality (adjusted hazard ratio, 0.34; 95% confidence interval, 0.16–0.71; P = .004).ConclusionsPerioperative statin therapy was associated with reduced mid-term mortality for patients undergoing cardiac surgery, irrespective of their baseline lipid status. This clinical evidence suggests that the beneficial effects of statins might extend beyond their lipid-lowering ability

A study of Texas programs of curriculum improvement through in-service education in senior high schools

The study was concerned with practices and recommendations for in-service education programs in relation to curriculum development in the State of Texas. The purpose of the investigation was to provide guidelines for administrators responsible for organizing and administering in-service education programs. The related literature was reviewed, and two survey instruments were developed. The instruments were pre-tested and a pilot study was conducted. The Texas Association of School Administrators endorsed the study. The questionnaire pertaining to practices was distributed to two hundred and thirty directors of instruction and the questionnaire pertaining to recommendations was sent to two hundred and thirty high school principals. Findings. Significant practices as reported by the directors of instruction are contained in the following list. 1. The cooperative approach is used in organizing, administering, and developing the philosophy of in-service programs. 2. The assistant superintendent for instruction is responsible for the district level in-service program. 3. The principal is responsible for in-service activities at the building level.
