Ansiedade, avaliação cognitiva e esgotamento na formação desportiva: estudo com jovens atletas

Este estudo analisa a importância dos processos de avaliação cognitiva na experiência de ansiedade e de burnout bem como a importância da avaliação cognitiva e da ansiedade na predição do burnout. Participaram nesta investigação 711 atletas (89 do sexo feminino e 622 do sexo masculino), com idades compreendidas entre os 12 e os 19 anos (M = 14.77; DP = 1.86). Os participantes responderam a um protocolo de avaliação composto por três instrumentos, além de um questionário demográfico: Escala de Ansiedade no Desporto-2; Escala de Avaliação Cognitiva e Questionário de Burnout para Atletas. Os resultados demonstraram que a avaliação cognitiva primária desempenha um papel fundamental na experiência de ansiedade e de burnout, dado que a perceção de ameaça correspondeu a maiores níveis de ansiedade e burnout e a perceção de desafio correspondeu a menores níveis nestas variáveis. Além disso, verificou-se que as dimensões da avaliação cognitiva primária, em conjunto com as dimensões da ansiedade, foram variáveis preditoras do burnout. Em suma, os resultados evidenciaram a importância da avaliação cognitiva no estudo dos estados emocionais dos atletas, sugerindo a continuação de investigações futuras neste domínio.

Assessment of cardiovascular risk factors in a rural community in the Brazilian state of Bahia

OBJECTIVE: To assess the frequency of cardiovascular risk factors in the rural community of Cavunge, in the Brazilian state of Bahia. METHODS: A cross-sectional study was carried out with 160 individuals (age > 19 years) randomly drawn from those listed in the population census of the Cavunge Project. The following parameters were studied: arterial hypertension, dyslipidemia, diabetes, obesity, smoking, waist-hip ratio (WHR), physical activity, and overall cardiovascular risk classified according to the Framingham score. The assessing parameters used were those established by the III Brazilian Consensus on Hypertension and the II Brazilian Consensus on Dyslipidemia. RESULTS: Of the randomly drawn individuals, 126 with a mean age of 46.6 + 19.7 years were included in the study, 43.7% of whom were males. The frequency of arterial hypertension was 36.5%; 20.4% of the individuals had cholesterol levels >240 mg/dL; 31.1% of the individuals had LDL-C levels > 130 mg/dL; 4% were diabetic; and 39.7% had a high-risk Framingham score. Abdominal obesity was observed in 41.3% of the population and in 57.7% of the females. High caloric-expenditure (HCE) physical activities were performed by 56.5% of the individuals. The HCE group had a greater frequency of normal triglyceride levels (63% vs 44%; P=0.05), no diabetes, and WHR tending towards normal (46% vs 27%, P=0.08) as compared with those in the low caloric-expenditure group. CONCLUSION: Cardiovascular risk factors, such as hypertension and hypercholesterolemia, are frequently found in rural communities. The greatest frequency of normal triglyceride levels and normal WHR in the HCE group reinforces the association between greater caloric expenditure and a better risk profile.

Electrophysiological Studies and Radiofrequency Ablations in Children and Adolescents with Arrhythmia

Background:Radiofrequency ablation is the standard non-pharmacological treatment for arrhythmias in pediatric patients. However, arrhythmias and their associated causes have particular features in this population.Objective:To analyze the epidemiological characteristics and findings of electrophysiological diagnostic studies and radiofrequency ablations in pediatric patients referred to the Electrophysiology Unit at Instituto de Cardiologia do Rio Grande do Sul, in order to characterize the particularities of this population.Methods:Cross-sectional study with 330 electrophysiological procedures performed in patients aged less than 20 years between June 1997 and August 2013.Results:In total, 330 procedures (9.6% of the overall procedures) were performed in patients aged less than 20 years (14.33 ± 3.25 years, age range 3 months to 19 years), 201 of which were males (60.9%). A total of 108 (32.7%) electrophysiological diagnostic studies were performed and of these, 48.1% showed abnormal findings. Overall, 219 radiofrequency ablations were performed (66.3%) with a success rate of 84.8%. The presence of an accessory pathway was the most prevalent finding, occurring in 158 cases (72.1%), followed by atrioventricular nodal reentrant tachycardia (16.8%), typical atrial flutter (3.1%) and extrasystoles originating from the right ventricular outflow tract (2.7%). Three patients developed complications during ablation (1.4%). Among congenital heart diseases, which occurred in 51 (15.4%) patients, atrial sept defect was the most frequent (27.4%), followed by ventricular sept defect (25.4%) and Ebstein's anomaly (17.6%).Conclusion:Electrophysiological study and radiofrequency ablation are effective tools for diagnosis and treatment of arrhythmias in the pediatric population.

Observações sobre papilomatose em bovinos

The A. A., in this paper, relate the observations on a bovine herd affected by papilloma or common warts; it was treated with the specific medicament "Figueirina", made in the "Laboratório de Biologia Veterinária", of Matias Barbosa, Minas Gerais, Brazil. In twenty-six affected animals, twenty showed complete cure after the treatment, three of them improved, and the other three didn't show any satisfactory results. Among the cured animals, twelve were young and eight were adult. The uncured animals were all adult. In most cases, the warts disappeared rapidly with two applications. In those animals that had resisted four applications, the warts didn't disappear, even with greater dosis. "Figueirina" showed more efficience in the treatment of young animals.

Avaliação de uma técnica in vivo para medir a infestação por ácaros do gênero Raillietia Trouessart (Acari) em bovinos

In vivo flushing of the ear canals with 50 to 100 ml collected all larvae in 100% of infested cattle. All adult mites were collected from 22 ou 27 parasitized ears (81.5%). Both stages adult and larva were collected from 18 out 22 parasitized ears (82%). The technique is adequate as a measure of prevalence, incidence, density/intensity of infestation as well as in vivo diagnosis. No damage to the host ear has been noticed.

Inequalities in Child Mortality in India: A District-Level Analysis

This paper measures the degree of inequality in child mortality rates across districts in India, using data from the 1981, 1991 and 2001 Indian population censuses. The results show that child mortality is more concentrated in less developed districts in all three census years. Further, between 1981 and 2001, the inequality in child mortality seems to have increased to the advantage of the more developed districts (i.e., there was an increasing concentration of child mortality in less developed districts). However, the inequality in female child mortality rates seems to have declined between 1991 and 2001, even as it increased – albeit at a slower rate than before – for male child mortality rates. In the decomposition analysis, it is found that while a more equitable distribution of medical facilities and safe drinking water across districts did contribute towards reducing inequality in child mortality between 1981 and 1991, different levels of structural change among districts were responsible for a very large part of the inequality in child mortality to the advantage of the more developed districts in all three census years. Other variables which played important roles in increasing inequality included a measure of infrastructure development, female literacy, and a social group status variable. The paper concludes with some brief comments on the policy implications of the findings.

Cognitive and Emotional Deficits Associated with Minor and Serious Delinquency in High-Risk Adolescents

This study aims at evaluating how minor and serious delinquency relates to cognitive and emotional functioning in high-risk adolescents, taking problematic substance use into account. In 80 high-risk adolescent males (13-19 years), the frequency of minor and serious offences committed over the last year was predicted, in multiple regression analyses, from problematic substance use, intellectual efficiency, trait impulsivity, alexithymia (inability to express feelings in words), and cognitive coping strategies. Both minor and serious delinquency were more frequent in adolescents with more problematic substance use and higher intellectual efficacy. Minor delinquency was further related to a tendency to act out when experiencing negative emotions, and difficulties in focusing energy on instrumental action when under stress; while serious delinquency was predominantly and strongly related to rigid and dichotomous thinking. The results underline the heterogeneous nature of delinquency, minor offences being primarily associated with emotional regulation deficits, while major offences are related with a lack of cognitive flexibility.

Late biliary complications in human alveolar echinococcosis are associated with high mortality.

AIM: To evaluate the incidence of late biliary complications in non-resectable alveolar echinococcosis (AE) under long-term chemotherapy with benzimidazoles. METHODS: Retrospective analysis of AE patients with biliary complications occurring more than three years after the diagnosis of AE. We compared characteristics of patients with and without biliary complications, analyzed potential risk factor for biliary complications and performed survival analyses. RESULTS: Ninety four of 148 patients with AE in Zurich had non-resectable AE requiring long-term benzimidazole chemotherapy, of which 26 (28%) patients developed late biliary complications. These patients had a median age of 55.5 (35.5-65) years at diagnosis of AE and developed biliary complications after 15 (8.25-19) years of chemotherapy. The most common biliary complications during long-term chemotherapy were late-onset cholangitis (n = 14), sclerosing cholangitis-like lesions (n = 8), hepatolithiasis (n = 5), affection of the common bile duct (n = 7) and secondary biliary cirrhosis (n = 7). Thirteen of the 26 patients had undergone surgery (including 12 resections) before chemotherapy. Previous surgery was a risk factor for late biliary complications in linear regression analysis (P = 0.012). CONCLUSION: Late biliary complications can be observed in nearly one third of patients with non-resectable AE, with previous surgery being a potential risk factor. After the occurrence of late biliary complications, the median survival is only 3 years, suggesting that late biliary complications indicate a poor prognostic outcome.

Active screening for pulmonary tuberculosis by chest x-ray among immigrants at the Swiss border

Summary : Aim: To assess the number of immigrants with pulmonary tuberculosis detected by chest x-ray screening at the Swiss border. Method: All adult immigrants entering Switzerland in 2004 were screened by chest x-ray (CXR). The number of radiological abnormalities suggestive of pulmonary tuberculosis, and the proportion requiring treatment for tuberculosis, were assessed retrospectively. The frequency of symptoms among immigrants with documented TB was compared with a sample of immigrants with a normal CXR. Results: Among 8995 immigrants, 8240 had a normal CXR, 630 had some abnormality not suggestive of active TB and 125 (1.4%) had a CXR suggestive of pulmonary TB. A final diagnosis of tuberculosis requiring treatment was made in SO (1 l with positive smear and culture, 16 with positive culture and 23 with negative culture), 57 had fibrotic lesions and 18 had another disease or a normal x-ray on control. The prevalence of symptoms did not differ between 27 immigrants with documented TB (smear+/culture+: 82%, smear-/ culture+: 75%), and 23 with smear-/culturetuberculosis (91%), but lower in 57 immigrants with fibrotic lesions (60%). Cough was more frequent among the 27 immigrants with documented TB (70%) than among 198 smokers without TB (37%) and among 229 non-smokers without TB (15%) Conclusions: Only 22% (27/125) of immigrants with CXR abnormalities suggestive of pulrnonary tuberculosis were documented by smear and/or culture and 40% (50/125) needed antituberculous treatment. 2/11 smear-positive immigrants would not have been detected by a questionnaire on symptoms. Rapport de synthèse : Le but de l'étude est d'évaluer le rendement du dépistage radiologique de la tuberculose pulmonaire chez les immigrés à l'entrée en Suisse. Méthode: parmi les immigrés adultes entrés en Suisse en 2004, qui ont tous passé un contrôle radiologique, le nombre de porteurs de clichés thoraciques suspects de tuberculose et la proportion de cas chez lesquels un traitement antituberculeux a été prescrit ont été évalués rétrospectivement. La fréquence des symptômes chez les immigrés atteints de tuberculose a été comparée à celle d'un groupe contrôle sans tuberculose. Résultats: parmi 8995 immigrés, 8240 avaient un cliché thoracique normal, 630 étaient porteurs d'une anomalie non suspecte de tuberculose active et 125 (1.4%) montraient des signes radiologiques suspects de tuberculose. Un diagnostic final de tuberculose nécessitant un traitement a été posé dans 50 cas (11 cas à frottis et culture positifs, 16 cas à culture positive, 23 cas à culture négative), 57 présentaient des lésions cicatricielles compatibles avec une ancienne tuberculose et 18 avaient une autre affection pulmonaire ou un cliché normal au contrôle. La prévalence des plaintes n'était pas différente entre les 27 immigrés porteurs d'une tuberculose documentée (frottis+ /culture+: 82%, frottis-/culture+ : 75%) et les 23 immigrés atteints d'une tuberculose non documentée (frottis-/culture-: 91%), mais elle était plus élevée que chez les 57 immigrés porteurs de lésions cicatricielles (59%). La toux était plus fréquente chez les 27 tuberculeux documentés (70%) que chez 198 fumeurs sans tuberculose (37%) et chez 229 non fumeurs sans tuberculose (15%). Conclusions: seuls 22% (27/125) des immigrés dont le cliché thoracique est suspect de tuberculose sont porteurs d'une tuberculose documentée par examen direct ou culture et 40% (50/125) nécessitent un traitement antituberculeux. Deux immigrants sur les 11 cas frottis positifs n'auraient pas été dépistés par un questionnaire.

Improving influenza vaccination rates in the elderly.

BACKGROUND: Vaccination coverage for influenza in the elderly remains low when the physician is the only person responsible for immunization. Integration of other health care workers may improve the coverage rate of at-risk groups. OBJECTIVES: To estimate vaccination coverage rate by using a strategy based on the systematic intervention of a health care professional proposing vaccination before the doctor's consultation, to evaluate the changes in coverage rates before and after introduction of this strategy, and to assess the feasibility of this intervention and the achieved coverage rate in family physician offices. STUDY DESIGN: Prospective study in a medical outpatient clinic and 5 family physician practices in Switzerland. POPULATION: Participants consisted of all patients 65 years or older attending a medical outpatient clinic during the vaccination period in 1999 (n = 401), patients 65 years or older regularly followed at a medical outpatient clinic in 1998 and 1999 (n = 195), and patients 65 years or older presenting to 5 family physician offices in 1999 (n = 598). OUTCOME MEASURED: Rates of vaccination coverage. RESULTS: Among all participants, vaccination coverage rates in 1999 were 85% at the medical outpatient clinic and 83% in family physician offices. Among participants regularly followed at the medical outpatient clinic, vaccination coverage increased from 48% in 1998 to 76% in 1999. Rates of refusal were 9% at the medical outpatient clinic and 14% in the family physician offices. CONCLUSIONS: The systematic intervention of a health care professional to suggest vaccination before the doctor's visit is an effective measure to achieve high coverage rate. Such a strategy also improves outpatient clinic or private practice efficiency by reducing pressures on physicians.

Factors related to transmission of and infection with Schistosoma mansoni in a village in the South-eastern Region of Brazil

In this transversal study, factors related to infection with and transmission of Schistosoma mansoni were explored. Based on stool examinations of two Kato-Katz smears of a single sample, the prevalences of schistosomiasis and geohelminths were established. In a multivariable analysis, sets of demographic, socio-economic and water contact pattern variables were tested for strength of relation with infection. Males presented a 3.39-times higher risk for infection than females. The age groups between 10-19 years and 20-30 years showed risks of infection 7.1- and 7.5-times higher, respectively, than the control age group between 0-10 years. Individuals practicing leisure activities had a 1.96-times higher risk than those without these activities. The malacological survey identified snails of the species Biomphalaria glabrata, Biomphalaria straminea and Biomphalaria tenagophila. Two exemplars of B. glabrata (0.53%) proved positive for S. mansoni. The socio-economic improvements observed in the locality suggest a protective and preventive effect towards infection with schistosomiasis, which requires further investigation with a longitudinal and more detailed study design. Considering our findings, a proposal for an integrated control program should be based on two pillars: one horizontal, which involves social empowerment and health education, and another more vertical, which delivers treatment and infrastructure improvements.

The impact of highly active antiretroviral therapy on the survival of vertically HIV-infected children and adolescents in Belo Horizonte, Brazil

The use of highly active antiretroviral therapy (HAART) for human immunodeficiency virus (HIV)-infected patients has reduced the number of acquired immune deficiency syndrome-related deaths worldwide. This study assessed the impact of HAART on the survival and death rates of vertically HIV-infected children and adolescents in Belo Horizonte, Brazil. Data were obtained from a historic cohort of vertically HIV-infected children and adolescents aged zero-19 years old who were admitted from March 1989-December 2004 and were followed until June 2006. Patients who used HAART were included if they were treated for at least 12 weeks. Of 359 patients, 320 patients met the inclusion criteria. The overall mortality rate was 9.7% [31/320; 95% confidence interval (CI): 6.0-13%]. The median survival for the non-HAART and HAART groups was 31.5 and 55.9 months, respectively (log rank = 22.11, p < 0.0001). In the multivariate analysis, the statistically significant variables were HAART and the weight-for-age Z score < -2, with HAART constituting a protective factor [relative risk (RR): 0.13; CI 95%: 0.05-0.33] and malnutrition constituting a risk factor (RR: 3.44; CI 95%: 1.60-7.40) for death. The incidence of death was 5.1/100 person-years in the non-HAART group and 0.8/100 person-years in the HAART group (p < 0.0001).
