Stress and success in dentistry. Some personality characteristics of successful dentists.

This article describes a study of relationships between a selected set of personality characteristics, as measured by the 16PF, and the success outcomes of a group of 109 dentists. Results indicate that Factor C (high ego strength), Factor F (liveliness and enthusiasm), Factor H (venturesomeness), Factor Q1 (experimenting), Factor Q3 (high self-concept integration), Factor Q4 (tenseness), Factor QII (anxiety) are significantly related to one or more index of success (satisfaction, size of practice, income and professional advancement). Findings are compared to results of earlier research concerning relationships between personality and stress related illness. Implications of findings are discussed in terms of the influence of personality on individuals' capacity to cope with occupational stress.

[Success and apparent success resulting from early cancer diagnosis (author's transl)].

Cancer screening techniques are of great value in improving the results of treatment of various tumours. Unfortunately screening and early diagnosis of cancers does not improve the prognosis in every case. Early diagnosis may lead to an apparent success without affecting the final outcome of treatment. Early diagnosis may even be harmful to the patient if the diagnostic and therapeutic methods lead to dissemination of the tumour, as has been shown by a number of authors. Consequently cancer screening and early diagnosis should be confined to those selected tumours which are not affected adversely by diagnostic methods.

Weathering the storm: Most maternal and environmental drivers of individual reproductive success do not scale up to population recruitment in a large herbivore.

Population growth depends upon individual survival and reproduction, but do drivers of individual reproductive success scale up to population recruitment? Factors affecting individuals may have little effect on population dynamics if individuals within a population experience different conditions. When seasonal resource availability is unpredictable and breeding season long, average conditions over a breeding cycle may poorly reflect the environment experienced by many individuals. We compared the drivers of individual reproductive success and population recruitment in an asynchronously breeding large herbivore, the eastern grey kangaroo (Macropus giganteus). We analysed 18 years of individual-based data using multivariate hierarchical Bayesian models to first identify the causal mechanisms relating population density, environmental conditions and maternal traits to individual success. We then assessed whether the drivers of individual reproductive success scaled up to determine population recruitment. Most maternal and environmental covariates strongly influenced individual reproductive success, with distinct effects on juvenile survival before and after pouch exit. Maternal traits had a greater influence in the pouch, whereas environmental conditions became increasingly important once young exited the pouch. Most drivers of individual reproductive success did not affect population recruitment. Recruitment increased with population density and mean body condition of adult females. Weather harshness had a weak positive effect on recruitment, which appeared independent of female age structure, previous recruitment or forage. Most drivers of individual reproductive success did not scale up to population recruitment. Birth asynchrony could buffer population recruitment against environmental variation such that variables affecting individual reproduction have little impact at the population level. Large herbivores that reproduce asynchronously may therefore be more resilient to environmental variability than synchronous breeders.

Factors influencing the success of ventricular defibrillation in man.

To define the factors influencing the success of emergency ventricular defibrillation, we identified 52 patients defibrillated at the University of Iowa Hospital during 1974--1976. Thirty-eight patients were successfully defibrillated at least once; 14 could not be defibrillated, despite multiple attempts. Comparisons between these groups revealed no significant differences in body weight, heart weight, energy per kilogram of body weight and energy per gram of heart weight. Factors that militated against successful defibrillation included a prolonged delay before the first defibrillatory shock (successful 7 +/- 7 minutes (SD); unsuccessful 17 +/- 13 minutes, p less than 0.001), acidosis (successful pH 7.36 +/- 0.22; unsuccessful pH 7.23 +/- 0.12, p = 0.05) and hypoxia (successful PO2 100 + 98 torr; unsuccessful PO2 40 +/- 67 torr; p = 0.06). These three conditions tended to occur together in individual patients. Metabolic factors are important in determining defibrillation success; however, the role of high-energy doses is uncertain.

Success in ambylopia therapy as a function of age: a literature survey.

It is frequently stated that amblyopia is not correctable after the age of 6 years. Many practitioners report marked success for older patients. To evaluate these conflicting reports, we analyzed the results from 23 published amblyopia studies. Our analysis indicates that substantial numbers of patients over age 6 were successfully treated. Success rates under age 6 were not significantly better than those in older patients when the criterion for success was achievement of 20/30 acuity or better. When a criterion of 4 lines improvement was used, success rates at all ages under 16 were quite similar; in patients 16 and over, success by this criterion was significantly less frequent, but even in this group success was achieved by 42% of the patients.

Drug choice as a self-handicapping strategy in response to noncontingent success.

In two closely related experiments, college student subjects were instructed to choose between a drug that allegedly interfered with performance and a drug that allegedly enhanced performance. This choice was the main dependent measure of the experiment. The drug choice intervened between work on soluble or insoluble problems and a promised retest on similar problems. In Experiment 1, all subjects received success feedback after their initial problem-solving attempts, thus creating one condition in which the success appeared to be accidental (noncontingent on performance) and one in which the success appeared to be contingent on appropriate knowledge. Males in the noncontingent-success condition were alone in preferring the performance-inhibiting drug, presumably because they wished to externalize probable failure on the retest. The predicted effect, however, did not hold for female subjects. Experiment 2 replicated the unique preference shown by males after noncontingent success and showed the critical importance of success feedback.

Impact of Integrated Continuous Team Midwifery Care on Breastfeeding Success within the Iranian Health System: A Randomized Controlled Trial.

INTRODUCTION: Supporting women during the perinatal period helps build confidence, strengthens early bonding between mother and baby, and encourages successful breastfeeding. Continuous midwifery care models are one of the ways that support women in this periods. OBJECTIVE: This study aimed to evaluate the effect of integrated continuous team midwifery care (ICTMC) in enhancing breastfeeding success in the Iranian health system. METHODS: In this randomized controlled trial, 200 low-risk primiparous women with a gestational age of less than 12 weeks were recruited from public health centers. Participants were randomly assigned to either the intervention group, which received continuous midwifery care throughout pregnancy, childbirth, and postnatal follow-up, or the control group, which received routine care. The primary outcomes were early skin-to-skin contact and breastfeeding success at the time of discharge and at 4-6 weeks postpartum. Data were analyzed using Stata, employing descriptive statistics, Chi-square, independent t-test, Phi/Cramer's V, and Cohen's d. The p < 0.05 is significant. Data were analyzed with SPSS 26. RESULTS: ICTMC groups were significantly more likely to initiate skin-to-skin contactearly skin-to-skin contact immediately after birth (92% vs. 74%, p < 0.001) and achieve successful breastfeeding at the discharge time (88% vs. 70%, p = 0.002) compared to the control group. At 6 weeks postpartum, breastfeeding success remained higher in the intervention group (82% vs. 65%, p = 0.004). CONCLUSION: Women with ICTMC, effectively support skin-to-skin contactearly mother-infant bonding and enhance breastfeeding success among low-risk primiparous women. Integrating this model into routine maternal care may improve perinatal outcomes.

Behavioral and fantasy measures of fear of success in children.

Fear of success was assessed for 61 fifth-, seventh-, and ninth-grade children using Horner's and Baruch's "fantasy" measures and a behavioral measure developed by the authors. Males and females did not differ significantly on fear of success as measured by the fantasy technique. Developmentally, male fear of success remained unchanged in the three grades tested, while female fear of success decreased from grade 5 to grade 7. The behavioral measure of fear of success tapped a drop in achievement striving in grade 7 for the female subjects. Results are discussed in light of a "situational" versus personality theory of the development of fear of success.

Incidence of circulatory arrest in patients with acute myocardial infarction in coronary unit. Mechanism of their genesis and factors conditioning successful resuscitation.

The incidence, circumstances, and mechanism of development of cardiac arrest in 786 patients with myocardial infarction treated at a coronary care unit within a five-year period were studied and clinical factors are analysed with respect to success of resuscitation. One or more episodes of cardiac arrest occurred in a total of 156 patients (19.8%). Of these, 25 (16.0%) were successfully resuscitated and 131 (84.0%) died. At the clinical ward where the patients had been transferred after the acute stage, cardiac arrest occurred in additional 22 patients, of whom two were successfully resuscitated. Thus, the total number of successfully resuscitated patients throughout the five-year period was twenty-seven. The results of resuscitation were poorer in elderly patients, in those with anterior infarction, and above all in patients with severe symptoms of mechanical heart failure. Anamnestic factors (chronic angina pectoris, previous myocardial infarction, hypertension, diabetes mellitus, ischaemic disease of the lower limbs) were not significantly associated with the results of resuscitation. Primary ventricular fibrillation was the principal mechanism of cardiac arrest in 24 of the 27 patients successfully resuscitated, and its total incidence in the investigated group was 3%. The prognosis of resuscitation in patients with primary ventricular fibrillation was very good, and in all of them the resuscitation was successful and permanent.

Fear of success-fact or artifact?

Each of 240 high school juniors and seniors wrote stories in response to one of four variations of the story cues used by Matina Horner to measure what has been called "fear of success." These cues described either Ann or John achieving success in medical school in a situation in which either all of the protagonist's classmates were men or there were equal numbers of men and women. Six different consequences of the success were assessed. Results indicated that male and female students perceived the depicted success in similar ways and that when the "deviance" aspect of Ann being alone in a class of men was removed, negative outcomes of success were lessened. The common interpretation of these stories as the writers' projections of their own personalities is challenged.

Attribution for success and failure as a function of perceived age.

Based on an attributional model of achievement-related behavior, it was predicted that success on the part of a young person and failure on the part of an old person, being expected outcomes, would be attributed to stable causes, whereas success on the part of an old person and failure on the part of a young person, being unexpected outcomes, would be attributed to unstable causes. Using a between-subjects experimental design, subjects were asked to estimate the probability that a young vs an old stimulus person would succeed in college and to judge the causes for his success or failure. Although there occurred no differences as a function of age in expectancy of success or attributions for success, failure on the part of the old stimulus person was attributed more to the stable causes of lack of ability and task difficulty, while failure on the part of the young stimulus person was attributed more to the unstable cause of lack of effort. The results were discussed in terms of those conditions under which negative stereotypes concerning the competency of the elderly will be considered appropriate and thereby exert an influence on evaluations.

Apical bearing and success with the Bausch and Lomb Soflens (polymacon) contact lens.

Thirty-three patients (63 eyes) were fitted with Bausch and Lomb soflens (polymacon) contact lenses. The initial lenses were selected with the mean posterior apical radius 0.45 mm flatter than the flat keratometer reading of the cornea (S.D. = +/-0.31 MM). Forty-eight eyes (76%) were successfully fitted and 15 eyes (25%) were unsuccessfully fitted. Among the successfully fitted eyes, 31 were fitted with the initial lens, 12 required steeper lenses, and 5 required flatter lenses. The final successfully fitted lenses were on the average 0.40 mm flatter (S.D. = +/-0.32 mm) than the flat keratometer reading of the cornea. The unsuccessfully fitted lenses were not significantly different than the successfully fitted lenses, being 0.47 mm flatter (S.D. = +/-O.32 mm) than the flat keratometer reading of the cornea. Although the central lens-cornea relationship is helpful in fitting the Soflens, the number of successful results are increased significantly by changing to a lens with different parameters when lens performance and patient response are not optimal.

Sex differences in 'fear of success' among British students.

Using a measure derived from Horner's studies of 'fear of success', the attitudes of three groups of British undergraduates towards success and failure were investigated. The results indicate ambivalence towards success and failure among both sexes, but neither the numerical analysis nor the kinds of responses indicated much of the overt sex-stereotype-based 'fear of success' found in the earlier American studies. Both sexes indicated some disillusionment with the 'success ethic'. Males showed somewhat greater anxiety about failure.

[Success and failure of the ventriculoperitoneal shunt in the treatment of hydrocephalus].

In ventriculoperitoneal shunting, the intraperitoneal location of the drainage site can be an additional cause of failure. In our series of 70 ventriculoperitoneal shunts, performed in infants and adults for treatment of hydrocephalus from various cause and of various type, failures of this kind manifested themselves usually early in the postoperative period either as a reflux of liquid, not attributable to the operative technique, into the subcutaneous pericatheter tract, or as a reappearance of the intracranial hypertension, without faulty functioning of the ventricular drain. The total success rate was 61% (43/70) but the age of the patient made a clear difference. In patients aged less than 5 months, we observed 11 successes in 33 cases (33%), in those aged less than 1 year, 14 successes in 36 (39%); patients with myelomeninogocele, wherein the shunting was usually done during the first month of life, fared badly; the role of age seems herein predominant. In patients aged more than 1 year, 29 successes in 34 cases (85%) were obtained; results were notably good in nearly all hydrocephalus of tumoral origin. We think the possible role of the "tightness" of the hydrocephalus has to be invoked as also the possibility of spontaneous remission. Ventriculoperitoneal shunting, devoid of the serious complications of ventriculocardiac shunting, is a simple and effective procedure in many cases of hydrocephalus. Means for more accurate prediction of the chances of success in the individual case are needed.
