Efficacy of high-intensity exercise training on left ventricular ejection fraction in men with coronary artery disease (the Training Level Comparison Study).

The purpose of this study was to compare high- versus low-intensity exercise training on the change in echocardiographic left ventricular ejection fraction (LVEF) from rest to peak exercise. Sedentary men with coronary artery disease, aged 30 to 70 years, were randomized to dynamic exercise training of either low intensity, 50% of maximal oxygen consumption, n = 89; or high intensity, 85% of maximal oxygen consumption, n = 111. No other interventions were imposed and patients were evaluated at 6 months and 1 year. Both exercise groups significantly increased exercise capacity without adverse events, but the increase was greater (p = 0.02) in the high-intensity exercise group. The mean exercise test rest-peak LVEF in the high-intensity group rose from 6.20% at baseline to 6.54% in 6 months and to 6.73% at 12 months, while the low-intensity group showed no improvement at 6 months and a decrease at 12 months. Multivariate analyses revealed that treatment group (high versus low intensity) significantly contributed to the change in rest-peak LVEF. When the exercise groups were subdivided by initial baseline LVEF < or = 50% versus > 50%, those with the higher LVEF in the high-intensity group showed a greater (p = 0.05) increase in the rest-peak LVEF from baseline to 1 year. Over a 1-year period, exercise capacity improved in both exercise-intensity groups, but more so in the high-intensity group, with no adverse events. The high-intensity group, compared with the low-intensity, showed more improvement in the rest-peak LVEF, especially in those with a higher LVEF at baseline.

Emergent literacy skills and training time uniquely predict variability in responses to phonemic awareness training in disadvantaged kindergartners.

The factors that predicted variability in responses to phonemic awareness training were investigated in kindergartners who live in poverty. Treatment children (n=42) received both analytic and synthetic phonemic awareness computer-assisted instruction, while controls (n=34) received no special training. Mean age of participants was approximately 5 years 7 months. Pretests included initial phonemic awareness, letter knowledge, word-level reading, invented spelling, vocabulary knowledge, and print concepts. Spelling skills emerged as the best consistent predictor of variability in phonemic awareness in response to instruction. We propose that relations between phonemic awareness and spelling skills are bidirectional: Spelling influenced growth in phonemic awareness and phonemic awareness contributed to growth in spelling skills. The amount of exposure that children had to the treatment intervention contributed uniquely to individual differences in posttest levels of phonemic awareness and spelling.

Influence of endovascular training on fellowship and general surgical training.

PURPOSE: As endovascular procedures develop, there is a risk of diminished training of residents and fellows in traditional open surgery. We evaluated the effect of our endovascular program, initiated in 1999 coincident with the Federal Drug Administration's approval of endoluminal vascular aortic grafts, on the number of endovascular procedures and open abdominal aortic aneurysm (AAA) repairs performed in comparison to national trends. METHODS: The experience of vascular fellows and chief residents at completion of training (1996-2002) was reviewed and compared with the national mean case numbers before and after initiation of our endovascular program. RESULTS: The development of an endovascular program increased the total number of aneurysms repaired at the Robert Wood Johnson (RWJ) Medical School from 49 +/- 15 to 92 +/- 8 per year (P < 0.01). The number of vascular operations performed by the RWJ fellow increased from 320 +/- 48 to 553 +/- 155 per year (P < 0.05). The number of operations performed nationally by vascular fellows also increased during the same period, but did not reach statistical significance. There was no change in the number of open AAA repairs performed by the RWJ fellow or nationally. There was also no change in the average number of vascular operations completed by RWJ chief residents or nationally (160 +/- 17 versus 157 +/- 1 and 192 +/- 4 versus 189 +/- 4, respectively; P > 0.05). However, the average number of open AAA repairs performed nationally by general surgical chief residents decreased from 10 +/- 0.3 to 9 +/- 0.4 (P < 0.05). CONCLUSION: An endovascular program can increase the total number of AAA repairs performed without influencing the total number of vascular operations performed by general surgical chief residents. There was a decrease in open AAA repairs performed nationally by general surgical chief residents. The advancement of endovascular therapies may decrease the number of open procedures available for trainees in both general and vascular surgery. Perhaps those that will specialize in the field of vascular surgery should have the benefit of those open procedures.

A novel approach to endourological training: training at the Surgical Skills Center.

PURPOSE: We investigated the effects of didactic teaching and supervised hands-on practice on endourological skills using high fidelity genitourinary bench models at a surgical skills laboratory. We also validated a global rating scale and checklist designed specifically for endourological tasks. MATERIALS AND METHODS: We assessed 17 urology residents for the ability to remove a mid ureteral stone using a high fidelity genitourinary model on 3 occasions, including a pre-test at the beginning of the study to assess baseline skills, after a didactic teaching session and after a supervised practice session on high fidelity models. Performance was graded according to a global rating scale, checklist, pass rating and time needed to complete task. RESULTS: Senior residents achieved significantly higher pre-test global rating scores than junior residents (p <0.01). One-way repeated measures analysis of variance revealed a significant effect of training on the endoscopic global rating score (p <0.001). Post-hoc tests demonstrated significant improvement in the global rating scores from the pre-test to the post-didactic session (p <0.05) and from the post-didactic to the post-practice session (p <0.01). Interrater reliability using the global rating scale was high (Pearson's r = 0.82, p <0.01). Significant but less powerful results were observed in the checklist score, pass rating and time. CONCLUSIONS: There was a positive effect of training at the surgical skills laboratory on endourological skills. The global rating scale showed good construct validity and reliability for assessing endourological tasks, more so than the checklist, pass rating or time.

[Continuous practice and advanced training in interventional cardiology. Recommendations for the assessment and maintenance of proficiency in interventional cardiology. A statement for physicians and advanced training units from the Section of Hemodynamics and Interventional Cardiology of the Spanish Society of Cardiology].

This report reflects the interest of the Section of Hemodynamics and Interventional Cardiology of the Spanish Society of Cardiology in increasing quality, safety and applicability of percutaneous procedures, by giving scientific keys aimed at improving related functions of teaching or planning in this field and enhancing competence and prestige of Spanish interventional cardiologists. The purpose of the document is to describe the importance of current interventional cardiology, to identify quality references and to establish minimum acceptable requirements for assessing and maintaining the competence of practicing or providing advanced training in this discipline. To achieve this goal, a search for a gold standard of the different techniques of general interventional practice was carried out, and predictors of postprocedural outcome were analyzed, as well as their relation with different kinds of circumstances. This analysis identified coronary angioplasty as the standard on which recommendations regarding competence in overall interventional cardiology standards of quality and assessment and maintenance of proficiency must be based. On the other hand, the strong influence of experience and knowledge of results has been documented, especially in high-risk or high-complexity settings. On this basis, the report establishes specific recommendations about proficiency for practice and advanced training. It also suggests that interventional cardiology should be considered as a subspecialty, of cardiology requiring specific credentials.

An automated voice advisory manikin system for training in basic life support without an instructor. A novel approach to CPR training.

Twenty-four paramedic students with previous basic life support training were randomised, performing cardiopulmonary resuscitation (CPR) on a manikin for 3 min without any feedback followed by 3 min of CPR with audio feedback from the manikin after a 2-min break, or vice versa. A computer recorded information on timing, ventilation flow rates and volumes and all movements of the sternum of the manikin. The software allowed acceptable limits to be set for all ventilation and compression/release variables giving appropriate on-line audio feedback according to these settings from among approximately 40 pre-recorded messages. Students who started without feedback significantly improved after feedback in terms of the median percentage of correct inflations (from 2 to 64%), with most inflations being rapid before feedback (94%), compressions of correct depth (from 32 to 92%), and the duration of compressions in the duty cycle (from 41 to 44%). There were no problems with the median compression rate, sternal release during decompressions, or the hand position, even before feedback. There were no significant differences in any variables with and without feedback for the students who started with feedback, or between the audio feedback periods of the two groups. It is concluded that this automated voice advisory manikin system, a novel approach to basic CPR training, caused an immediate improvement in the skills performance of paramedic students.

Recommendations for training in performance and interpretation of stress echocardiography. Committee on Physician Training and Education of the American Society of Echocardiography.

Stress echocardiography has emerged as a clinically useful procedure in the management of patients with ischemic heart disease and other conditions. However, the accuracy of this test relies on the ability of those who carry out the technical aspects of the test and depends critically on proper interpretation of the images. Appreciation of wall motion abnormalities is generally acknowledged as one of the most difficult skills to master in echocardiography. There is consensus that this is also one of the most difficult skills to teach. Appreciating stress-induced changes in wall motion, which sometimes are subtle, requires a significant commitment to initial training in this skill and its maintenance. This document provides recommendations for physician training in stress echocardiography.

T1-weighting of Hahn echo-trains in the stray-field for deuterium: prospects for imaging using long echo-train summation.

Hahn-echoes have been observed in stray-field gradients of 37.5 T/m and 74.5 T/m for deuterium in heavy water in a number of forms: liquid, ice, and coordinated in solid copper sulfate and silica gel. In the diamagnetic samples, the application of many pulses (> 1000 or more) in long pulse-trains produced many sustained echoes. This lengthening of T(echo) is caused by T1-weighting of the components of the Hahn echo (even in the absence of spin-locking). In contrast, for the paramagnetic complex, the shortening of T1 greatly reduces T(echo) and only few echoes are obtained. A new protocol for stray field imaging is suggested when T1 is long: long echo-train summation (LETS). The observed magnetisation is much greater for heavy ice than for heavy water because the line-width, and hence the thickness of the excited slice, is greater.

Cognitive problem-solving skills training and parent management training in the treatment of antisocial behavior in children.

This study evaluated the effects of problem-solving skills training (PSST) and parent management training (PMT) on children (N = 97, ages 7-13 years) referred for severe antisocial behavior. Children and families were assigned randomly to 1 of 3 conditions: PSST, PMT, or PSST and PMT combined. It was predicted that (a) each treatment would improve child functioning (reduce overall deviance and aggressive, antisocial, and delinquent behavior, and increase prosocial competence); and (b) PSST and PMT combined would lead to more marked, pervasive, and durable changes in child functioning and greater changes in parent functioning (parental stress, depression, and overall symptoms). Expectations were supported by results at posttreatment and 1-year follow-up. PSST and PMT combined led to more marked changes in child and parent functioning and placed a greater proportion of youth within the range of nonclinic (normative) levels of functioning.

Cue exposure with coping skills training and communication skills training for alcohol dependence: 6- and 12-month outcomes.

AIMS: Cue exposure treatment (CET) has shown promise in preliminary studies with alcoholics, and Communication Skills Training (CST) has been found beneficial, especially in intensive treatment programs. The aim of the present study was to investigate the effects of CET and CST in a larger controlled study when both were added to intensive treatment programs. DESIGN AND INTERVENTIONS: A 2 x 2 design investigated the effects of CET with urge coping skills training compared to a meditation-relaxation control, and CST compared to an education control when all were added to intensive treatment programs for alcoholics. SETTING: The sites were the inpatient or partial hospital substance abuse treatment programs at a private psychiatric hospital, a state-funded residential facility and a VA medical center. PARTICIPANTS: Patients diagnosed with alcohol dependence without active psychosis were eligible. MEASUREMENTS: Participants were assessed for quantity and frequency of drinking, alcohol cue-reactivity, responses to high risk simulations and urge specific coping skills. FINDINGS: Of 100 treated patients, 86% provided 6-month and 84% provided 12-month follow-up data. Patients who received either CET or CST had fewer heavy drinking days in the first 6 months than control patients. In the second 6 months, CET continued to result in fewer heavy drinking days among lapsers and interacted with CST to decrease quantity of alcohol consumed. CST resulted in fewer alcohol-related problems reported at 12 months. CET resulted in greater reductions in urge to drink in a measure of simulated high-risk situations. CET also resulted in greater reports of use of coping strategies during the follow-up, and many of the urge-specific strategies taught in CET were associated with reduced drinking. CONCLUSIONS: Both CET and CST continue to show promise as elements of comprehensive alcohol treatment programs. Limitations and directions for future research are discussed.

Task and training requirements analysis methodology (TTRAM): an analytic methodology for identifying potential training uses of simulator networks in teamwork-intensive task environments.

A methodology designed to identify potential application areas for use of networked simulations is presented. The technique, known as task and training requirements analysis methodology (TTRAM), has been independently applied to the analysis of numerous US military aircraft simulator networking requirements, and appears to effectively discriminate tasks that are prone to skill decay, that are critical to mission success, that require high levels of internal and external teamwork, and that require additional training support.

Fractioned reaction time in power-trained and endurance-trained athletes under conditions of fatiguing isometric exercise.

Fractionated knee extensor and plantar flexor reaction time (RT) components were assessed in a group of eight weightlifters and eight long distance runners. Following a 4-day period of baseline stabilization for each muscle group, a 50% maximal voluntary contraction (MVC) holding-time exercise was administered. Results showed that the runners had longer premotor times (PMT) than the weightlifters in the knee extensors, but had much faster PMTs than the lifters in the plantar flexor condition. Compared to previously reported investigations using non-athletes, the data for the present sample of athletes indicated faster total reaction times(TRT) in both the knee extensors and the plantar flexors. A resistance of 15% MVC applied during the RT task resulted in a lengthening of the motor time (MT) component in both groups prior to exercise. However, while knee extensor resisted motor time was lengthened by the exercise task, no such lengthening occurred in plantar flexor resisted RT. It is concluded that power-trained and endurance-trained athletes exhibit difference in response to a fractionated RT task, under both baseline and fatiguing exercise conditions.

Embracing the new paradigm of assessment in residency training: an assessment programme for first-year residency training in anaesthesiology.

Assessment of clinical competence is facing a paradigm shift in more than one sense. The shift relates to test content, which increasingly covers a broader spectrum of competences than mere medical expertise, and to test methods, with an increasing focus on testing performance in realistic settings. Also there is a shift in the concept of assessment in that instruction and assessment are no longer seen as being separate in time and purpose, but as integral parts of the learning process. The nature of the new paradigm for assessment is well described but the challenge to programme directors is to specify the evaluation situations and develop appropriate methods. This paper describes the intrinsic rational validation process in outlining an assessment programme for first-year anaesthesiology residency training according to the new paradigm. The applicability to other residency programmes and higher-level training in anaesthesiology is discussed.

Integrating geriatrics into clinical training, research training, board certification, and continuing education in infectious diseases: meeting review and commentary.

Although adults aged 65 years and older constitute the most rapidly growing segment of the U.S. population, geriatric issues have not typically been a focus of training in infectious diseases (ID). Underrecognition of the unique aspects of geriatric care, apathy toward this population, and the feeling that "we're all geriatricians" (and thus know geriatric medicine) all contribute to this problem. This article summarizes the recent meeting focused on integrating geriatric principles within ID training at all levels. The ID/geriatric interface as an attractive area for basic and clinical research is emphasized.

Nutrition training in graduate medical (residency) education: a survey of selected training programs.

Because limited information exists about nutrition training of residents, we studied the teaching practices of nationally recognized nutrition programs. Two hundred thirty-eight nutrition educators and 787 residency-program directors identified 160 institutions with strong nutrition training. The 23 highest-ranked programs were surveyed and 7 were visited. The results showed that 1) clinically active physician-nutritionist role models are the key elements in teaching residents clinical nutrition; 2) multidisciplinary nutrition support teams are valuable learning resources unless they function primarily as technical support services; 3) nutrition elective rotations, although highly effective, are taken by a minority of residents; 4) the nutrition curriculum should include practical learning materials and conferences; and 5) a research environment is important to attract qualified physician-nutritionist role models. A major deficit is teaching nutritionally based approaches to disease prevention in the ambulatory setting. Finally, a shortage of nutrition-oriented physician role models is probably the major constraint in teaching nutrition to residents.

Graylyn Conference Report. Recommendations for reform of clinical pathology residency training. Conjoint Task Force of Clinical Pathology Residency Training Writing Committee.

The Graylyn Conference Report of the conjoint ACLPS, ASCP, APC, and CAP task force is prompted by the growing realization that without reform of the clinical pathology residency curriculum the future of clinical pathology practice may be in jeopardy. The conclusions reached at the ASCP-sponsored Colorado Springs IV Conference on Clinical Pathology Residency Training laid the groundwork for this report on curriculum reform. The goal is the creation of scientifically oriented clinical pathology practitioners capable of serving as consultants to other physicians of managing laboratory resources, and of playing leadership roles in an increasingly complex health-care system. Recommendations are described under the headings of patient care roles, graduated responsibility, analytical and technical training, laboratory management and informatics, and basic and applied research. In terms of reforming the structure and content of the curriculum, it is recommended that basic laboratory rotations be preceded by either a single didactic general 4- to 6-week orientation, or a series of shorter orientations incorporated into each rotation. The introductory and rotation phase should be 9 to 12 months in duration. It is further recommended that the remaining 6 to 9 months of the 18-month core be an integrated experience in which the resident practices Clinical Pathology by assuming service responsibilities for several laboratory sections simultaneously.

Infectious disease manpower in the United States--1986. 2. Changes in practice patterns over time and training needs. Manpower and Training Committee, Infectious Diseases Society of America.

Infectious disease-trained internal medicine physicians responding to a questionnaire survey (n = 1802) reported minor differences in time spent in patient care versus laboratory-based research whether they subsequently became practitioners or academicians. Both practitioners and academicians ranked hospital epidemiology first, followed by knowledge of hospital antibiotic policies in order of importance for new trainees to be taught. Internists with greater than 12 months of training in infectious diseases were divided into private practice versus academically based groups, and their distribution of time spent in various professional activities was analyzed by 5-year intervals for each cohort. These studies confirmed an increasing proportion of time spent in infectious disease-related patient care for new practitioners. Over time, patient care activities decreased and administrative activities increased in all groups. These data are important for estimating future manpower needs.

Body weight-supported treadmill training versus conventional gait training for people with chronic traumatic brain injury.

OBJECTIVES: To compare body weight support treadmill training (BWSTT) to conventional overground gait training (COGT). DESIGN: Randomized controlled trial. SETTING: Residential rehabilitation center. PARTICIPANTS: Twenty subjects with chronic traumatic brain injury (TBI). INTERVENTION: The BWSTT or COGT for 15 minutes plus 30 minutes of exercise 2 days per week, for 3 months. MAIN OUTCOME MEASURES: Functional Ambulation Category (FAC), Functional Reach (FR), Timed Up and Go; gait velocity, step width (BOS) and step length differential using instrumented gait mat. RESULTS: Step width approached the norm without between-group differences. Step length differential improved significantly more for the COGT. CONCLUSIONS: Physical therapy can improve gait for patients more than 6 years post-TBI. The COGT is more effective than the BWSTT for improving gait symmetry during overground walking.
