[A study on simultaneous and successive Delboeuf illusions from the standpoint of the theory of set].

An attempt was made to examine whether or not the simultaneous Delboeuf illusion and the successive one were based on the same perceptual process. By the method of the fixed set, the subject's inner process (set) during the occurrence of the illusions was investigated in Experiment I. The results indicated that his set toward the Delboeuf illusion figure was not changed when only the inducing circle was presented first, but that his set was changed at the moment the inducing circle disappeared and the two circles of identical size were presented. Experiment II examined his perception when there was a time delay between the presentations of the inducing circle of the Delboeuf illusion figure and the other two circles. In that situation, the simultaneous Delboeuf illusion and the successive one should occur successively. The results of Experiment III suggested that the transitional change from the simultaneous Delboeuf illusion to the successive one, which had been observed in the previous study, was due to a change in the judgement of the subject who experienced these two different phenomena successively.

Physiological factors associated with the success in marathon running.

Marathon running is the most gruelling athletic event in international sport. Success of well trained athlete largely depends upon his perfect coordination of movements in relation to speed and optimum physiological adjustments. In order to identify the physiological factors which play crucial contributory role in successful marathon runners an evaluation study was conducted on 7 successful Indian athletes from among many competitors. Results of the study were compared between the 1st and the 7th rankers vis-a-vis the world champion in this event. Results indicated that the maximal aerobic power and economy in 'work' involved in marathon running were most important factors for the success in this event. In addition, a comparison of the blood lactic acid level of Indian with that of the world champion revealed that the latter could sustain at 85% of his maximal aerobic power for 2 hours compared to 78% and 62% of 1st and 7th ranker Indian athletes. There was not much of a difference between the world and Indian champion in this respect. Further, thermoregulatory efficiency was also found to play an important contributory role in determining success in this event. It is considered that a suitable index incorporating all the above factors is likely to be the most appropriate screening procedure in the evaluation programme of marathon runners for the reasons as discussed.

Community integration of mentally retarded adults: community placement and program success.

The extent of community and program success of 166 mentally retarded clients placed into a community-based program was evaluated over a 9-year period. Twenty predictor variables measuring institutional factors, client characteristics, training variables, and community characteristics were related to community or program success. Successful community placement was associated with sensorimotor and work skills, appropriate social-emotional behavior, gender, and family acceptance of community placement and involvement with the interdisciplinary team process. Program success was associated with language and psychomotor skills, education received prior to community placement, community and institution size, and family involvement. Sixteen percent of the clients were reinstitutionalized into either the state mental retardation facility or a mental health facility. Factors associated with successful placement and program progression were discussed as was a model for future deinstitutionalization research.

Negotiating a successful return to work program.

This article has examined selected reasons why companies resist implementation of return to work programs. The reasons include many fears that companies can readily justify. Nearly all the fears can be eliminated when the occupational health nurse applies both nursing and management principles. As a specialized line manager in the company, with a specialty in people and systems management, the occupational health nurse is the most likely person to plan and implement a successful program. To design, implement, and manage the plan to a successful end, the occupational health nurse must enhance skills in language, salesmanship, and quantifying results. Success must be measured in both people and dollar terms to have relevance to the company, its bottom line, and its employees. People results, the harder of the two to measure, have value in helping to establish positive attitudes of program participants toward the company. People results also help prevent the development of disability syndrome by ill or injured employees by keeping them connected to work and productivity. People results also can be measured by the change in culture the return to work program is likely to produce among managers and employees. The resulting culture will reflect a sense of caring by the company about employees, and expectation that manipulation of the company by opportunists will be reduced, as scarce company resources will be conserved. The early return to work program is managed within employee capabilities in a therapeutic environment during the recovery process. In the long term, financial success of the return to work program can be measured by reduced costs per claim annually. Using the nursing, management, financial, and marketing principles discussed in this article, the occupational health nurse can improve chances of negotiating implementation of a successful early return to work program.

Cumulative number and morphological score of embryos resulting in success: realistic expectations from in vitro fertilization-embryo transfer.

OBJECTIVE: To define statistical thresholds for the number and morphological score of embryos transferred that would be predictive of reproductive success in an IVF program. DESIGN: A retrospective review of patient records. SETTING: The Mount Sinai Medical Center Assisted Reproductive Technologies Program. PARTICIPANTS: One hundred women who underwent IVF-ET for a diagnosis of tubal occlusion and later delivered viable infants. RESULTS: The mean number of embryos transferred before achieving live birth was 10.7 +/- 7.9 (mean +/- SD), with one half of patients achieving success within the first seven embryos transferred, and 95% achieving success within 25 embryos. For high quality embryos, the numbers were 7.5 +/- 6.3, 5, and 17, respectively, and, for the cumulative embryo score, a measure of both embryo morphology and metabolic activity, were 114.2 +/- 86.0, 83, and 280, respectively. Greater than 50% of live births occurred within the first two ET attempts. CONCLUSIONS: Although more than half of patients achieved reproductive success within the first two ETs and the first five high quality embryos transferred, after this threshold, fecundity declined rapidly. The calculation of cumulative embryo scores offered additional prognostic information. While all prior attempts to define IVF-ET failure have done so by including patients who did not become pregnant, we have found an analysis of our successes to be a useful adjunct in counseling patients.

Influence of rapid weight gain after the weigh-in on success in collegiate wrestlers.

UNLABELLED: We investigated whether acute weight gain between the weigh-in and competition was associated with success in a collegiate wrestling tournament. Wrestlers at the NCAA championships were weighed at the official weigh-in and again just before the first round of the tournament (20 h later). Weight gain and the weight discrepancy between first-round opponents were calculated (N = 607 excluding heavyweights). Indices of success included season record (% wins in total matches), tournament seeding, the sum of the advancement and placement points scored during the tournament (team points), and final placement in the tournament. ANOVA showed no differences in weight variation between placewinners and non-placewinners, or across placewinners only. Correlation coefficients among weight variables and indices of success were also low (P > 0.05). Multiple logistic regression, used to determine whether weight gain or weight discrepancy between opponents contributed to success in the first round of the tournament, revealed that neither variables was predictive of first-round outcome even after attempting to account for differences in ability (e.g., forcing team points into the regression first). CONCLUSION: neither acute weight gain after the weight-in or the weight discrepancy between opponents in the first round influenced success in a collegiate wrestling tournament.

[Predictors of treatment success after microsurgical operation of lumbar intervertebral disk displacement].

As far as medical decision making is based on weighing up individual risks and chances of a certain patient receiving a certain treatment, some knowledge is required about signs and symptoms which are associated with a certain outcome: they are called risk factors, or predictive factors. In lumbar intervertebral disc surgery, the most frequent undesired effect of the treatment is unsuccessfulness. Reviewing the literature about risk factors for unsuccessfulness, one recognizes a lot of unconfirmed or even contradictory findings. This inconsistency can possibly be attributed to the common use of a very simplified, unidimensional definition of the target variable "success of treatment". That is why we performed a prospective observational trial on 109 patients in whom the success of lumbar intervertebral disc microsurgery was assessed after half a year using six different target variables. The rate of treatment success varied considerably, from 44% (when "return to previous occupation" served as the target variable) to 91% (with regard to "subjective contentedness"). Further target variables were intensity of sciatica, intensity of low back pain, activities of daily living, and postoperative paresis, giving intermediate success rates. We were able to identify some risk factors (for instance, duration of sick leave and of the recent pain episode, preoperative paresis, intensity of psychosomatic complaints), each of them being relevant to some of the target variables, but none of them associated with all of the target variables. We conclude that the multidimensional rating of treatment successes seems to promote risk research in multidimensional diseases.

Percutaneous transluminal coronary angioplasty. Its success rate and affecting factors.

From December 1987 to October 1983, percutaneous transluminal coronary angioplasty (PTCA) was performed in 302 patients with 392 diseased vessels and 440 lesions. The success rate was 93.71% in 302 patients, 94.90% in 392 diseased vessels and 95.00% in 440 lesions. The success rate was 98.92% in Type A lesion, 95.71% in Type B lesion, and 86.57% in Type C lesion (A vs B P = NS, A vs C P < 0.01). There were 55 lesions with total or subtotal occlusion, the success rate was 89.09% (93.10% in Type B lesion and 84.62% in Type C lesion). As to the diseased vessels, the success rate was 95.65% in LAD, 94.38% in LCX and 93.75% in RCA. The results showed no significant difference. In this series, acute ischemic complications were found in 6.59% (29/440). Of these 29 lesions, 23 were treated successfully, 5 developed Q wave myocardial infarction and 1 died.

[Identification of intracavitary electrograms predictive of success in ablation of anomalous pathways by radiofrequency].

PURPOSE: To analyze the characteristics of atrial (A) and ventricular (V) electrograms, AV and VA intervals relation to determine a precise radiofrequency ablation site. METHODS: A and V electrograms (EG) recorded at successful (group 1) and unsuccessful (group 2) sites in 22 patients submitted to RF catheter ablation were identified. Specific criteria as morphology, AV and VA intervals relation and the presence of an accessory pathway were analyzed. RESULTS: The shortest AV interval with a VEG that precedes the delta wave in the onset of the QRS recorded at the EKG leads was the best outcome predictor. The AV connection potential was only recorded in five out of 22 patients and did not interfere with the result when not present. The interval measured between the onset of the V electrogram and the onset (delta wave) of the QRS complex (V-d) varied from -4.9 to -11msec (m = 7.5 + 1.6) in G1 and from -6 to 15msec (m = 9.6 +/- 3) in G2 (p = 0.03). Unsuccessful sites had the VEG preceding the delta wave but the AV interval was not short. Success in the retrograde mapping of target site seems to be the presence of an atrial potential that occurs simultaneously with the nadir (S wave) of the QRS complex. CONCLUSION: Specific criteria such as morphology of the local VEG, a short AV or VA intervals and a VEG that precede the onset (delta wave) of the QRS identified a successful site for RF ablation. When present the accessory pathway potential indicates a high chance of a successful ablation; however when not present did not decrease the chance of success.

A comparison of the success rates of resident and attending strabismus surgery: discussion.

Residency training involves surgery by resident surgeons at various levels of experience and proficiency, supervised by an experienced attending physician. We reviewed the results of strabismus surgery performed at four institutions with two residency training programs. Five hundred twenty-two cases with follow up greater than 6 weeks were evaluated. These cases included 315 attending procedures and 207 resident procedures under direct attending supervision. Success was defined as a strabismic deviation of 8 prism diopters or less. Average postoperative follow up was 57 weeks and did not differ between groups. There was no statistical difference between the resident success rate of 58% (121/207) and the attending success rate of 69% (217/315) after adjusting for population differences. The average final deviation of the patients postoperatively was 7 delta for the attending group and 10 delta for the resident group. Amblyopia was significantly more frequent in the resident cases (P < .001). Adjustable sutures were used significantly more often in attending cases (P < .0001). This study supports the premise that resident strabismus surgery is as successful as attending surgery. (Abstract reproduced from Wisnicki HJ, Repka MX, Raab E, et al.

[Fertilization in vitro--success rates and registration].

There is great uncertainty and concern about the reliability of success rates in IVF. This is because of lack of agreement about what defines success and how this should be measured. Success should be reported on the basis of real birth rates measured against all stimulation cycles and all women accepted for treatment. This is because the purpose of IVF is to alleviate infertility, and couples (or women) who seek treatment will only consider live birth as a successful result. All clinics should be required to submit these results to a national registry in order to retain accreditation by the Ministry of Health. The purpose of the registry is to make information available to couples (or women) about their real chances of giving birth to a child. This will also make it possible to evaluate whether the economic resources are used efficiently, a requirement which may help to standardize the definition of success used in medical journals.

Evaluations of surgery resident performance correlate with success in board examinations.

BACKGROUND: American Board of Surgery (ABS) In-Training Examination (ABSITE) scores correlate with future examination scores, but faculty evaluations of resident skill have not been shown to predict future performance. METHODS: Objective and subjective evaluations during the past 15 years in our columnar university surgical residency were reviewed to assess their ability to predict success on the qualifying (written) and oral (certifying) examinations offered by the ABS. RESULTS: The ABSITE scores correlated with success on the qualifying examination (multiple R2 = 0.473). Subjective assessments of resident knowledge at any level did not correlate with ABSITE or qualifying scores, but above average scores did predict success on the certifying examination (chi 2, p < 0.005). Chief-year ABSITE total percentile score and score of first qualifying examination also predicted success on the certifying examination. The attrition rate in our nonpyramidal program was 23%, of which more than one half were voluntary. One of 11 residents leaving the program has subsequently attained ABS certification. CONCLUSIONS: This study shows that faculty's subjective evaluations predicted resident success on the ABS certifying examination and also endorses the ABS oral examination as an effective measure of the candidate's ability to communicate surgical knowledge.

On those wrecked by success: a clinical inquiry.

Freud's description of those wrecked by success outlines conflicted oedipal triumph as the central underlying dynamic in this character type. It does not distinguish those patients who avoid success from those driven to achieve and then wreck their success. We present a complex picture that we believe is prototypic of patients who destroy their success. A clinical case illustrates our point of view. We emphasize the developmental problems we believe typical of patients who dramatically wreck the success they achieve. We hope to extend rather than replace Freud's landmark contribution to our understanding of this type of character pathology.

Predicting pulpectomy success and its relationship to exfoliation and succedaneous dentition.

This study evaluated factors that affected pulpectomy (PE) success and its effect on the succedaneous tooth's eruption and enamel formation. Sixty-five of 250 patients with PEs met the selection criteria and yielded 81 zinc oxide-eugenol PEs (30 incisors, 51 molars) followed a mean time of 90.8 months. Overall PE success was 77.7% with no difference between molars and incisors (P = 0.53). Enamel defects were observed in 18.7% of succedaneous teeth and were related (P = 0.005) to the pre-existing infection causing excess root resorption (>1 mm preoperative root resorption = 44.4% defects) but were not related to overretention of ZOE filler (P = 1) or length of fill (P = 0.36). The PE procedure was not related to causing succedaneous tooth defects since teeth replacing PEs showed no significant increase in the incidence of defects compared with untreated contralateral controls (P = 0.99). There was a 20% incidence of succedaneous tooth anterior cross-bite or palatal eruption following incisor PEs and 21.6% ectopic eruption of premolars following primary molar PEs. Most PEs (95.9%) were lost at their normal exfoliation time or earlier, but 35.8% needed extraction due to overretention by soft tissue at the time of shedding. Pulpectomy success rates showed that the most important preoperative predictor was the amount of primary tooth root resorption. Greater than 1 mm of root resorption resulted in only a 23.1% success rate, which was significant (P = 0.001). Pulpectomies filled short or to the apex had a significantly greater success (P = 0.011) than long fills. Pulpectomies correctly done do not appear to contribute to adverse effects on succedaneous tooth formation but have a 20% chance of altering the path of permanent tooth eruption.

[Cushing's disease: successful surgery through improved preoperative tumor localization].

OBJECTIVE: To study the effect of improved preoperative tumour localisation on the outcome of transsphenoidal surgery for Cushing's disease. DESIGN: Retrospective. SETTING: University Hospital Rotterdam, the Netherlands. METHODS: The case records were studied of 61 patients, operated on for Cushing's disease due to a corticotrophin-secreting microadenoma (diameter < 10 mm), in the period January 1985-September 1995. From 1985, preoperative tumour localisation was performed with computed tomography (CT), from 1989 with Magnetic Resonance Imaging (MRI) and Bilateral Simultaneous Inferior Petrosal Sinus Sampling (BSIPSS). The definition of a successful operation was: morning serum cortisol < 500 nmol/l, and of cure: morning serum cortisol < 140 nmol/l or 24-hr cortisoluria < 250 nmol. RESULTS: In 1985-1988, a microadenoma was localised preoperatively in 8/22 patients (36%), the operation was successful in 12 (55%), of which 4 (18%) were cured. In 1989-1991, a microadenoma was localised in 12/15 patients (80%), the operation was successful in 11 (73%), of which 4 (27%) were cured. In 1992-1995 a microadenoma was localised preoperatively in 23/24 patients (96%), the operation was successful in 19 (79%), of which 17 (71%) were cured. In the cured group, there was a low incidence (< 10%) of postoperative hypopituitarism in all three periods. There were 1, 0 and 1 recurrences of Cushing's disease respectively after initial cure. CONCLUSION: In our institution, improved preoperative localisation of corticotrophin-secreting hypophyseal microadenomas was associated with an important increase of success and cure rate of transsphenoidal surgery, while there was no increase in postoperative hypopituitarism or recurrences of Cushing's disease.

Translating public health research into public health practice: outcomes and characteristics of successful collaborations.

For over five years we have been involved in a series of collaborations between academic public health and state and local public health organizations. This article briefly describes the outcomes produced and under development by these collaborations and delineates and discusses some characteristics we now hypothesize will predict successful academic/practice collaboration. These collaborative projects with public health organizations in Alabama, Indiana, and New Mexico have produced outcomes that influenced the organization of the agencies and the allocation of resources within the agencies. The collaborations also have contributed to the body of literature concerning management processes in public health agencies and influenced the teaching of strategic management to students of health services. Our experiences and interactions led to the identification of 10 characteristics we believe predict successful academic and practice collaborations, discussed in three groups as (1) characteristics of successful academic collaborators, (2) characteristics of successful collaborating public health organizations, and (3) characteristics of successful collaborative projects.

The true rate of success in argon laser eyelash thermoablation.

Argon laser thermoablation has a success rate of 50% typically, when success is defined as an absence of recurrence of any eyelash per lid treated. When success is redefined as an absence of recurrence per eyelash treated, the success rate increases to 76% to 93%. Laser thermoablation potentially offers selective eyelash ablation with minimal inflammation and adjacent tissue damage. Its true rate of success may be better than previously indicated.

Improved long-term survival after heart transplantation predicted by successful early withdrawal from maintenance corticosteroid therapy.

BACKGROUND: Short-term studies suggest that cardiac transplant immunosuppression without maintenance corticosteroids is feasible in selected patients. However, concern exists as to the long-term effects, specifically the possibility of increased morbidity and mortality because of late allograft rejection and allograft coronary artery disease. METHODS: We retrospectively reviewed the records from 441 consecutive heart transplantation procedures done in 416 patients with use of an immunosuppressive protocol that attempted corticosteroid withdrawal within 2 months of transplantation. forty-two patients died or underwent retransplantation during the first 3 months and were excluded from further analysis. Analysis focused on demographic and long-term outcome variables (including death, rejection, retransplantation, and infection). RESULTS: Thirty percent (111) of eligible patients (374) met the definition of successful early steroid withdrawal. Only male gender independently predicted successful withdrawal. Mortality, both short and long term, was significantly lower in patients in whom successful early withdrawal from corticosteroids was achieved than in patients in whom the early attempts failed (1.7% per year versus 4.7% per year; p < 0.0001). The prevalence of late acute allograft rejection (more than 1 year after transplantation) was lower in patients successfully withdrawn from steroid therapy early after transplantation (0.07 pt-yr of follow-up versus 0.15 pt-yr; p = 0.002). Multivariate analysis of the entire group identified incidence of infection (p = 0.001), older age (p = 0.001), failed early steroid withdrawal (p = 0.006), and female gender (p = 0.016) as independent predictors of mortality. CONCLUSIONS: Successful early corticosteroid withdrawal identifies a subgroup of "immunologically privileged" patients with a low risk for long-term mortality and is not associated with an increased prevalence of late rejection or clinically significant coronary artery disease.
