Self-esteem moderator or mediator between perceived stress and expectancy of success.

Relationships between perceived stress, self-esteem, and expectancy of success were examined, and the moderating and mediating effects of self-esteem between perceived stress and expectancy of success were explored. Participants (48 women, 27 men) completed self-rating scales measuring perceived stress, self-esteem, and expectancy of success. Negative relationships were obtained between perceived stress and self-esteem and between perceived stress and expectancy of success. Self-esteem and expectancy of success were positively associated. Moderated multiple regression analysis yielded no moderating effect of self-esteem between perceived stress and expectancy of success; however, a moderating effect of self-esteem was obtained using regression techniques.

Visual detection of technical success and effectiveness of teat cleaning in two automatic milking systems.

Technical success and effectiveness of teat cleaning and the management factors associated with them were evaluated in 9 automatic milking herds. In total, 616 teats cleaned with a cleaning cup and 716 teats cleaned with rotating brushes were included. Technical success and the effectiveness of teat cleaning, including the location and nature of the dirt, were evaluated visually. On average, 79.9% of teat cleanings with a cleaning cup, and 85.0% of those cleaned with brushes succeeded technically; that is, the teat was correctly positioned in the cleaning device throughout the whole cleaning process. The difference between use of teat cups and brushes was significant. However, because technical success of teat cleaning is strongly dependent on herd characteristics, these results should be interpreted with caution. Factors associated with the technical success of teat cleaning with a cleaning cup were herd, days in milk, behavior of the cow, teat color, and teat location. For rotating brushes, behavior of the cow, teat location, udder and teat structure, and days in milk were associated with technical success. Excessive udder hair and technical failure of the automatic milking machine also caused a few technically unsuccessful teat cleanings with a cleaning cup. Teats with technically successful teat cleanings were evaluated for the effectiveness of teat cleaning. From originally dirty teats, the cleaning cup had a significant advantage over the brushes in the percentage of teats that became clean or almost clean during the cleaning process (79.8 vs. 72.9%). Teat orifices were least effectively cleaned compared with the teat barrel and apex. Bedding material (peat, sawdust, or straw) on the teat was cleaned almost completely. Factors associated with the effectiveness of teat cleaning were teat cleanliness before cleaning, herd, teat cleaning method, and teat condition. The variation among herds indicates the likelihood that herd management factors can be adjusted to improve milking hygiene. There is also a need to improve the precision and effectiveness of the teat cleaning mechanisms of automatic milking systems.

Predictors of success of repeated injections of single-dose methotrexate regimen for tubal ectopic pregnancy.

The purpose of this study is to evaluate predictors of success of repeated injections of methotrexate in the single-dose regimen for the treatment of tubal ectopic pregnancy. All patients who had ectopic tubal pregnancy and were treated with a single dose regimen were retrospectively identified. 126 patients were treated with methotrexate. Among them, 39 patients were adequate for this study. 33 were treated with the 2nd dose and 27 were successfully cured. Additionally, 6 who were injected with the 3rd dose were all cured as well. Therefore, in our study, the success rate for the repeated injections of methotrexate was found to be 84.6% (33/39). The mean initial beta-hCG level was significantly lower in patients who were successfully treated than in patients who failed (3915.3+/-3281.3 vs. 8379.7+/-2604.4 IU/mL, p<0.05). The success rate is 96% when the beta-hCG level is less than 6,000 IU/mL and is 58% when beta-hCG is greater than 6,000 IU/mL (OR=18.57, 95% CI 1.86-185.89). The initial beta-hCG level is the only factor that has significant meaning as predictor of success of repeated injections of methotrexate in the single-dose regimen. Repeated injections of methotrexate may be particularly effective when the initial beta-hCG level is below 6,000 IU/mL.

The seven S's for successful management.

Becoming a successful manager in a health care agency is, for most new managers, an awesome goal. Successful management is more than knowledge of leadership roles and management functions that can be learned in school or educational workshops. Successful management involves effective use of both the manager's affective and cognitive domains. Mentoring and apprenticeship with a successful nurse leader is for many novice managers a highly valuable way to learn management skills since this allows for techniques with a successful nurse manager to be visualized and then modeled. "Seven S's" that provide a framework for managerial success are discussed.

Impact of implant interdependency when evaluating success rates: a statistical analysis of multicenter results.

PURPOSE: When evaluating the outcome of oral implant treatment, a statistically important aspect to consider is whether any dependency exists among implants placed within the same patient/jaw. If one implant fails, will the risk of subsequent failures increase, i.e., will any of the remaining implants also fail? In an attempt to study this question, the aims of the present study were to statistically determine if the suggested hypothesis was valid, i.e., whether dependency exists among implants in the same patient/jaw, and to determine how failure lifetable analysis should be calculated. MATERIALS AND METHODS: In the present study, multicenter trial material consisting of 1.738 oral implants in 487 patients from 4 separate studies was used. First, any dependency among implants within the same patient/jaw was determined; thereafter, cumulative success rates were calculated for one implant per patient (chosen randomly), and the range of variations in the randomized success rates was also calculated. This was then compared with the cumulative success rates based on the entire material. RESULTS: The statistical analysis showed that a dependency among the implants existed prior to their functional loading, i.e., the risk for an implant failure among the remaining implants in the same patient/jaw increased after the first failure had occurred. CONCLUSION: Both study design and statistical analysis are of importance when comparing success rates from various investigations, since dependency among implants in the same patient/jaw does exist and may influence the success rates. Consequently, it is suggested that only one randomly selected implant from each patient should be considered when calculating implant success rates.

Changing leaders: the board's role in CEO succession ... roundtable discussion.

The selection of a CEO is one of the most important- and risky-events in the life of any company. Yet the way CEOs are chosen remains little discussed and little understood. The succession process has traditionally unfolded behind closed doors--some observers have even likened it to the election of a pope. To shed light on what works and what doesn't in CEO succession, the authors lead a roundtable discussion with five distinguished corporate directors: Philip Caldwell, George D. Kennedy, G. G. Michelson, Henry Wendt, and Alfred M. Zeien. Collectively, the five directors have participated in dozens of successions, either as board members or as CEOs. In a lively and frank exchange of views and experiences, the roundtable participants explore a broad range of questions: What can a company do to ensure a successful succession? How should management-development and succession processes be managed? How should the board work with the sitting chief executive during the process? What makes for a strong CEO candidate? When should outside candidates be considered? How much competition should be encouraged among potential CEO candidates? What role should executive search firms play? What role should former CEOs play after they are succeeded? Their conversation illuminates a corporate challenge that is as difficult as it is important.

Predicting RGP daily wear success.

PURPOSE: While most clinicians agree that fitting of rigid gas permeable (RGP) lenses is the preferred treatment strategy for some types of patients, many patients have difficulty adapting to full-time daily wear of these lenses. The Contact Lens Extended Wear Study (CLEWS) is a randomized, controlled clinical trial in which subjects are first adapted to full-time RGP daily wear prior to randomization to either high or medium oxygen transmissibility (Dk/L) RGP lenses for 12 months of extended wear. The CLEWS pre-randomization data provide an opportunity to examine the reasons some patients fail to adapt to RGP daily wear and to determine whether a patient's demographic, historical, and ocular characteristics can be used to predict RGP daily wear success. METHODS: From 1,809 individuals who expressed interest in RGP lenses, 411 subjects passed the CLEWS screening criteria and were fit with high Dk lenses (mean Dk = 92 x 10(-11) [cm2/sec][mL 02/mL x mmHg]). The fitting strategy included minimum apical alignment, lid attachment, centration, and average lens diameters of 9.2 mm. Success was defined as a minimum of 14 hours per day without adverse ocular responses that would contraindicate either full-day daily wear or extended wear. RESULTS: Of the 411 subjects, 286 (69.6%) were successful with RGP extended wear. Among the 125 failures, 50 were based on clinician findings (e.g., cornea, vision, compliance), while 75 subjects chose to discontinue wear because of unacceptable comfort or poor vision. Multivariate linear logistic regression modeling shows that younger patients with greater corneal curvature (K) and less predicted residual astigmatism have a higher probability of RGP daily wear success. CONCLUSIONS: Our study showed that RGP lenses can be fit with a relatively high rate of success and that many of those patients who elect to discontinue RGP daily wear report unacceptable comfort as the primary reason. We propose a Bayesian statistical method that will assist clinicians in selecting those candidates for RGP daily wear who are most likely to adapt successfully.

Beyond IQ: broad-based measurement of individual success potential or "emotional intelligence".

Individual-difference correlates of life success were studied using 302 participants aged 17-46 years (107 men, 195 women) and 31 individual-difference measures. Factor 1 (Relaxed Temperament) included Trait Pleasure-Displeasure (+), Anxiety (-), Depression (-), Optimism (+), Self-Esteem (+), Covert Index of Employee Reliability (+), and Functional Flexibility (-). Positively loading scales on Factor 2 (Arousable Temperament) were Trait Arousability, Emotional Empathy, Emotional Thinking, and Affiliative Tendency. Factor 3 (Disciplined Goal Orientation) included Delay of Gratification (+), Impulsivity (-), Procrastination (-), Patience (+), Integrity (+), Adaptive Coping (+), and Intelligence (+). Positively loading scales on Factor 4 (Dominant Temperament) were Trait Dominance-Submissiveness, Social Competence, Achieving Tendency, and Self-Actualization. Factors 1, 3, 4, and intelligence exhibited positive relations with all peer-rated criterion measures of life success. Trait Arousability, representing Factor 2, correlated negatively with relationship, physical, work, and overall success. Physical attractiveness correlated positively with all success measures except emotional success. When success measures were regressed against intelligence and personality scales or factors, intelligence did not account for variance beyond that explained by personality.

Success rates of formocresol pulpotomy and indirect pulp therapy in the treatment of deep dentinal caries in primary teeth.

PURPOSE: This study was performed to retrospectively evaluate treatment of deep caries in primary molars with formocresol pulpotomy (FP) and indirect pulp therapy (IPT). METHODS: 133 primary molars with deep caries approaching the pulp were treated with FP (N = 78) or IPT (N = 55) and followed 2-7 years. All IPTs received immediate stainless steel crowns (SSCs); 61 FPs got an immediate SSC, 13 an intermediate restorative material (IRM), and 4 amalgam. Thirteen IPTs and 25 FPs had pre-operative pain compatible with a diagnosis of reversible pulpitis. Treatment notes and radiographs were independently assessed. RESULTS: Overall IPT success was 93% (51/55) versus 74% (58/78) for FP. Molars with pain compatible with a diagnosis of reversible pulpitis were successfully treated by IPT 85% (11/13) versus 76% (19/25) for FP. FP-treated molars exhibited earlier exfoliation 38% (30/78), while all IPT molars exhibited normal exfoliation. FPs receiving immediate SSCs had 50/61 (82%) succeed; FPs restored with an IRM temporary succeeded 5/13 (39%), amalgam 3/4 (75%). CONCLUSIONS: IPT success was significantly higher than FP (P = 0.01) in the treatment of deep caries. Both IPT and FP were successful in treating teeth with pain compatible with the diagnosis of reversible pulpitis. FP significantly hastened the exfoliation of pulpotomized primary molars (P = 0.001). IPT in primary teeth can be successfully used in a one step procedure. SSCs placed immediately after FP significantly increased FP success vs. FP followed by IRM temporary (P = 0.01).

[Predictive factors of successful treatment of lower caliceal calculi with Edap LT02 extracorporeal lithotripsy].

OBJECTIVE: To determine the predictive factors of success of extracorporeal shock-wave lithotripsy (ESWL) for lower caliceal stones. PATIENTS AND METHODS: The case files of 100 patients with a single stone in the lower pole of the kidney, ranging in size from 6 to 25 mm, treated by EDAP LTO2 extracorporeal lithotripsy between 1994 and 1997, were studied. Pretreatment intravenous urography was reviewed to assess the characteristics of the stone, to measure the pyelocaliceal angle and to study the anatomy of the lower pole of the kidney. RESULTS: The overall stone-free rate at 3 months was 57%. The success rate was 67.18% for stones smaller than 1 cm and 38.88% for stones larger than 1 cm. Stones denser than bone were successfully treated in 45.5% of cases, those less dense than bone were successfully treated in 71.11% of cases. The success rate was 86.04% when the pyelocaliceal angle was greater than 90 degrees and 35.08% when this angle was less than 90 degrees. The stone-free rate was 75% when the caliceal stalk was less than 3 cm and 37.5% when the stalk was greater than 3 cm. CONCLUSION: In this series, the size of the stone, its density, the pyelocaliceal angle and the length of the caliceal stalk were predictive elements of the success of ESWL for lower caliceal stones. The pyelocaliceal angle was the most significant factor. A very dense stone on the plain abdominal film with a diameter of 1 cm or more and presenting unfavourable anatomical factors should be treated by percutaneous nephrolithotomy as the first-line procedure.

Predictive factors for successful early prosthetic ambulation among lower-limb amputees.

OBJECTIVE: To predict successful prosthetic ambulation for patients immediately transferred to an inpatient rehabilitation facility after amputation surgery. METHODS: Seventy-five individuals with lower-limb amputation were studied at a tertiary acute care and rehabilitation facility. Successful prosthetic ambulation, defined as the ability to ambulate with a prosthesis at least 45 m, was measured in addition to other key demographic and medical factors. RESULTS: Sixty-eight percent were successful prosthetic ambulators at rehabilitation discharge. The absence of residual-limb contracture and a longer length of stay during rehabilitation showed a significant relationship to successful prosthetic ambulation with regression analysis. Younger age was modestly correlated to outcome. There were no significant differences when comparing success of the early rehabilitation program with surgical level or etiology of amputation. For successful prosthetic users, mean wear time at rehabilitation discharge was 5.7 hours with a mean distance walked of 67 m. Of those who failed this approach, 70% were related to a failure of wound healing. CONCLUSIONS: In this cohort, 68% of patients who were selected for a trial of early prosthetic rehabilitation ambulated using a prosthesis at rehabilitation discharge. This approach appears to be more effective for younger patients without contractures who are medically stable to participate in the rehabilitation process.

Telehealth success: evaluation framework development.

Implementing telehealth applications represents a substantial investment of resources, which is one reason why success is of great interest. Many research and evaluation studies have investigated measures of successful telehealth systems. However, the term "telehealth" represents a wide range of variables including clinical application, characteristics of the information being transmitted, temporal relationships of data transfer and the organizational context. These sources of variability pose many challenges for evaluation as well as for building a cumulative history of research. A conceptual framework is required that assists in categorizing results and drawing conclusions based on an accumulation of findings. One measure of "success" in health care is quality patient care and this reflects a primary reason for ICT investments. For this reason, Donabedian's work in evaluating quality provides the basis for the proposed framework. DeLone and McLean's definitions of IS success assist in conceptualizing Donabedian's structure-outcome-process variables in a telehealth context. Multiple evaluation approaches have been used to address different types of questions. Prior to the technologies being introduced to clinical care, there are usually many studies to demonstrate their effectiveness. Health Technology Assessment examines a broader context than the technology alone, including costs and comparing alternatives that would exist in the absence of telehealth. It considers performance measures; outcomes; summary measures, operational considerations, and other issues. Program Evaluation examines use of the technology to provide a service or deliver a program. Evaluation questions often address whether the program goals have been met and if it is operating as expected. Perhaps of greater concern than the evaluation approach taken is generalizability of findings. Recent studies have given inadequate attention to defining what is done (i.e. comparison of telehealth to most appropriate alternative), identifying the beneficiaries of telehealth (i.e. ensuring randomly selected participants take part) and what is measured (i.e. including benefits, drawbacks and side effects of telehealth). Evaluation efforts and frameworks have identified "success" factors such as technical acceptability of the system, cost/benefit/effectiveness, organizational support, satisfaction, recruitment and retention, client outcomes such as quality of life, acceptance by consumers and providers. Less is known about the relationship among these variables and whether the findings around one variable are generalizable to other settings or applications. For example, organizational support may be essential for successful provider-patient interactions via videoconference, which result in higher quality of life. A conceptual framework would assist in accumulating this type of evidence and supporting more advanced research efforts.

The in situ anterior vaginal wall sling: predictors of success.

PURPOSE: We assessed the outcome of the in situ anterior vaginal wall sling for stress urinary incontinence, identified any predictors of success and reviewed the current literature on this topic. MATERIALS AND METHODS: We identified all patients who underwent an isolated anterior vaginal wall sling procedure in a 16-month period. Charts were reviewed and telephone interviews were performed to assess the success rate of the procedure and identify parameters that may influence outcome. The pertinent literature was identified. RESULTS: Of the 42 patients identified 39 had evaluable data available. The overall success rate was 79.5% at an average 19-month followup. Abdominal Valsalva leak point pressure 50 cm. water or greater was identified as a significant predictor of success (p = 0.002). The success rate was 93% and 40% in patients with a Valsalva leak point pressure of 50 or greater and less than 50 cm. water, respectively. The pertinent literature was reviewed. CONCLUSIONS: The anterior vaginal wall sling is effective for stress urinary incontinence. In patients with a Valsalva leak point pressure of 50 cm. water or greater the success rate is 93%. We recommend the anterior vaginal wall sling procedure in these patients but different treatment in those with Valsalva leak point pressure less than 50 cm. water.

The success of emergency pulpotomies in primary molars.

PURPOSE: The purpose of this retrospective study was to assess the success of pulpotomies performed on an emergency basis and restored with a temporary zinc-oxide eugenol restorative material. METHODS: Records were collected from 216 pulpotomies in primary molars performed on an emergency basis by pediatric dental residents at the University of Florida pediatric dental clinic between July 1999 and June 2001. The selection criteria include teeth with a positive history of pain but with absence of clinical and radiographic signs of pulp degeneration. Formocresol was the medicament used and the teeth were restored temporarily with a reinforced zinc-oxide eugenol material. Treatment success or failure was determined, at the definitive restorative appointment, by the presence or absence of clinical and/or radiographic pathology. The time interval between emergency and definitive treatment appointments, tooth-type, arch, age, and gender were the variables analyzed in this study. Chi-square analysis was used to assess the effect of the different variables on the outcome of the treatment. RESULTS: Sixty-four teeth were available for assessment in the two-year period. A 53% success rate was observed, if the tooth was evaluated and restored with the definitive restoration, within the first 90 days post-emergency treatment. A 31% success rate was observed after 365 days. These results were statistically significant (P=0.016). Patients younger than six years old showed statistically significant higher chances for success than older children did (P=0.018). No significant differences were found for gender, type of tooth, or arch. CONCLUSIONS: The low success rate found during the first three months post emergency treatment may be attributed to undiagnosed, subclinical inflamed pulp, while long-term failure may be associated with microleakage of the temporary restorative material.

[Clinical role of flow velocity of left atrial auricle for prediction of short and long term success of cardioversion in patients with non-valvular atrial fibrillation].

INTRODUCTION: Echocardiographic parameters for predicting cardioversion (CV) outcome and long-term sinus rhythm (SR) maintenance in patients with nonvalvular atrial fibrillation (AF) are not accurately defined. AIMS: The authors aim was to evaluate the role of left atrial appendage (LAA) flow velocity detected by transesophageal echocardiography before CV for prediction of short and long-term (1 year) outcome of CV in patients with nonvalvular AF. METHODS: One hundred and nine patients (66 males, mean age: 57 +/- 13 years) with nonvalvular AF lasting more than 48 hours but less than 1-year duration underwent transthoracic and transesophageal echocardiography before either electrical or pharmacological CV attempt. RESULTS: Cardioversion was successful in restoring SR rhythm in 83 (76%) and unsuccessful in patients 26 (24%). Mean LAA peak emptying flow was higher in patients with successful than in those with unsuccessful CV (36.7 +/- 14.7 vs 26.3 +/- 9.2 cm/sec; p < 0.01). At multivariate analysis the left LAA emptying velocity > 32 cm/sec was the only independent predictor of CV success. Seventy-four out of the 83 patients with successful CV had a complete follow-up of 1 year. At the end of the 1-year follow-up, 40 of the 74 (54%) patients who underwent successful CV preserved the SR. Mean LAA peak emptying velocity was higher in patients remaining in SR for 1 year than in those with AF relapse (40.3 +/- 15.6 vs 32.2 +/- 12.2 cm/sec cm/sec; p < 0.001). On multivariate analysis, only the mean LAA peak emptying velocity > 39 cm/sec and the use of preventive antiarrhythmic drug treatment predicted the continuous preservation of SR during 1 year. CONCLUSION: In patients with nonvalvular AF, measurement of precardioversion LAA flow velocity profile by transesophageal echo cardiography provides valuable information for prediction of both short and long-term success of CV.

[Factors of the successful radiofrequency catheter ablation to the slow pathway in patients with uncommon atrioventricular nodal reentrant tachycardia].

We studied the clinical features and factors of successful catheter ablation for common and uncommon atrioventricular nodal reentrant tachycardia(AVNRT). The study population consisted of 41 consecutive patients, 33 with common type AVNRT (16 males mean age of 57.8 years), and 8 patients with uncommon type AVNRT (4 males, mean age of 57.1 years). In all patients with common type AVNRT, the earliest atrial activation during tachycardia was recorded at the His bundle region. The effective ablation sites were located in the medial septal area and all cases were successfully ablated without complication. In patients with uncommon type AVNRT, dual pathway was observed in 5 patients(63%) and triple pathway in 3 patients(38%). The earliest atrial activation during tachycardias was recorded at the ostium of the coronary sinus. Radiofrequency ablation therapy was performed during sinus rhythm in 5 patients, and during tachycardia in 3 others. The effective ablation sites were located at the posterior septal area around the coronary sinus ostium. All cases were successfully ablated without any major complication, but one case had second-grade atrioventricular block after ablation. There were no significant differences between the common and uncommon type AVNRT cases with regard to the therapeutic success rate, the mean application number or the total energy applied. However, the successful ablation sites were different between the two groups. We concluded that radiofrequency catheter ablation would be effective in patients with both common and uncommon types AVNRT. Selective ablation at the site of the retrograde slow pathway exit was the most important factor for successful catheter ablation for uncommon type AVNRT. However, it should be performed only after careful analysis, taking into account the complex mechanism of uncommon type AVNRT.

[Success rate of direct pulp capping with calcium hydroxide].

Aim of this retrospective study was to evaluate the success rate of direct pulp-capping treatment using calcium hydroxide-containing agents according to the age of the patient, the type of tooth and the person who performed the treatment. Over a period of seven years a total of 659 patients were treated. 763 direct pulp-cappings were recorded. From these 308 patients a total of 359 pulp-cappings (= 100%) were reexamined one to eight years after treatment. 45.1% of the reexamined teeth were in males and 54.9% in females. 61.7% of the treated teeth were in the upper and 38.8% in the lower jaw. Out of the 359 teeth (= 100%) the success rate was 61% (219 teeth); while 113 teeth (31.4%) had received a root canal treatment and 27 (7.6%) had been extracted. In this study the success rate depended on the group of teeth. It decreased continuously from the anterior teeth to the molars. The central incisors showed the highest (83.3%) and the wisdom teeth the lowest (38.9%) success rate. In addition, the success rate decreased with increasing age of the patients. The most successful treatments (76.4%) were registered in the group of patients, aged 10-19 years.
