title: Stages of changes for fruit and vegetable intake and their relation to the nutritional status of undergraduate students

description: Objective : To assess the nutritional and dietetic profile of freshman Nutrition undergraduate students, and its association with stages of changes (Transtheoretical Model) for fruit and vegetable intake. Methods : Demographic (age and gender), anthropometric (body mass index and waist circumference) and nutritional (pattern of fruit and vegetable intake) data were obtained. The Transtheoretical Model was used to identify the stages of change for fruit and vegetable intake. Food consumption was assessed with a questionnaire developed by the Ministry of Health. The significance level considered for all statistical tests was 0.05 (p&lt;0.05). Results : From 433 eligible students, anthropometric measurements were taken from 219 (50.6%), and 299 (69%) underwent food intake evaluation. The sample included undergraduate students with a low frequency of adequate fruit and vegetables intake (29.8%), being the majority (64.9%) of them classified as at the preparation stage to increase the intake of these food groups. Prevalence of adequate fruit and vegetables intake was higher among students at the action/maintenance stages (83.3%) compared to those at the precontemplation/contemplation (18.3%) and at the preparation stages (32.0%). Students at the preparation stage presented the highest medians for body mass index (p=0.004) and waist circumference (p=0.039) compared to those at the precontemplation/contemplation stages. There was no association between fruit and vegetables intake and the presence of overweight or abdominal obesity (p=0.373). Conclusion : This instrument is effective to predict the food intake and, even among aware individuals and ready to change their food behavior, the prevalence of nutritional risk is high.

title: Is there any relation between anthropometric indices and decrease in seminal parameters?

description: Objective : To investigate the influence of anthropometric indices on seminal parameters. Methods : Men who underwent treatment for conjugal infertility during the period of October, 2011, to March, 2012, were randomly selected. Patients with any prior diseases related to sperm alterations were excluded. Patients were submitted to an anthropometric evaluation to obtain body mass index, and the seminal analysis was made through a spermogram. Two anthropometric methods of classification were used: body mass index (normal and altered) and abdominal circumference (&lt;94cm and &gt;94cm). Data were analyzed by statistical tests. Results : The group with the altered body mass index presented lower volumes of ejaculated volume and a larger percentage of patients with abdominal circumference &lt;94cm presented with progressive forms of spermatozoa below reference values. However, in the statistical tests, there was no significant difference. Conclusion : No significant difference was found in the sperm quality relative to the body mass index or abdominal circumference.

title: Coaching leadership: leaders' and followers' perception assessment questionnaires in nursing

description: Objective : To describe the development, content analysis, and reliability of two questionnaires to assess the perception of nurse leaders, nurse technicians, and licensed practical nurses − coached in the practice of leadership and the relation with the dimensions of the coaching process. Methods : This was a methodological study with a quantitative and qualitative approach, which had the goal of instrumentation in reference to the construction and validation of measuring instruments. The instrument proposition design was based on the literature on leadership, coaching, and assessment of psychometric properties, subjected to content validation as to clarity, relevance, and applicability in order to validate the propositions through the consensus of judges, using the Delphi technique, in 2010. The final version of the questionnaires was administered to 279 nurses and 608 nurse technicians and licensed practical nurses, at two university hospitals and two private hospitals. Results : The Cronbach’s alpha value with all items of the self-perception instrument was very high (0.911). The team members’ instrument of perception showed that for all determinants and for each dimension of the coaching process, Cronbach’s overall alpha value (0.952) was considered quite high, pointing to a very strong consistency of the scale. Confirmatory analysis showed that the models were well adjusted. Conclusion : From the statistical validation we compared the possibility of reusing the questionnaires for other study samples, because there was evidence of reliability and applicability.

title: Analysis of smoke cessation rate and profile of former smokers living in Belo Horizonte and Metropolitan Region

description: Objective : To estimate the smoking cessation rate and to identify possible associated factors. Methods : Individuals from the Metropolitan Region of Belo Horizonte (MG) aged 15 years or more who responded to the smoking supplement of the National Household Sample Survey were selected (n=1,297). An estimate was made of the tobacco-use cessation rate relative to the 95% confidence interval. To verify factors associated with smoking cessation, Pearson’s χ2 test or Student’s t test were used. Results : The general smoking cessation rate was 56.7% (95% confidence interval: 52.3-61.1), with 57.7% among men and 55.5% among women. The associated factors were higher age and income. Among the 19 individuals who had stopped smoking for less than 12 months, 52.6% had been seen by a physician or healthcare professional in the previous 12 months, and 60% of them were oriented to stop smoking, but only 1 (16.7%) had been oriented at a unit of the public national Unified Healthcare System. Conclusion : Despite high rates of smoking cessation, the methods made available by the Unified Healthcare System did not show good results. It is necessary to enhance the healthcare programs that aim to reduce the proportion of smokers in the population. Such measures can have a positive long-term influence in droping mortality and morbidity rates associated with smoking and the costs for healthcare services.

title: Learning effect of computerized cognitive tests in older adults

description: Objective To evaluate the learning effect of computerized cognitive testing in the elderly.Methods Cross-sectional study with 20 elderly, 10 women and 10 men, with average age of 77.5 (±4.28) years. The volunteers performed two series of computerized cognitive tests in sequence and their results were compared. The applied tests were: Trail Making A and B, Spatial Recognition, Go/No Go, Memory Span, Pattern Recognition Memory and Reverse Span.Results Based on the comparison of the results, learning effects were observed only in the Trail Making A test (p=0.019). Other tests performed presented no significant performance improvements. There was no correlation between learning effect and age (p=0.337) and education (p=0.362), as well as differences between genders (p=0.465).Conclusion The computerized cognitive tests repeated immediately afterwards, for elderly, revealed no change in their performance, with the exception of the Trail Making test, demonstrating high clinical applicability, even in short intervals.

title: Clinical and epidemiological profile of patients with valvular heart disease admitted to the emergency department

description: Objective To evaluate the clinical and epidemiological profile of patients with valvular heart disease who arrived decompensated at the emergency department of a university hospital in Brazil.Methods A descriptive analysis of clinical and echocardiographic data of 174 patients with severe valvular disease, who were clinically decompensated and went to the emergency department of a tertiary cardiology hospital, in the State of São Paulo, in 2009.Results The mean age of participants was 56±17 years and 54% were female. The main cause of valve disease was rheumatic in 60%, followed by 15% of degenerative aortic disease and mitral valve prolapse in 13%. Mitral regurgitation (27.5%) was the most common isolated valve disease, followed by aortic stenosis (23%), aortic regurgitation (13%) and mitral stenosis (11%). In echocardiographic data, the mean left atrial diameter was 48±12mm, 38±12mm for the left ventricular systolic diameter, and 54±12mm for the diastolic diameter; the mean ejection fraction was 56±13%, and the mean pulmonary artery pressure was 53±16mmHg. Approximately half of patients (44%) presented atrial fibrillation, and over one third of them (37%) had already undergone another cardiac surgery. Conclusion: Despite increased comorbidities and age-dependent risk factors commonly described in patients with valvular heart disease, the clinical profile of patients arriving at the emergency department represented a cohort of rheumatic patients in more advanced stages of disease. These patients require priority care in high complexity specialized hospitals.

title: SeptiFast for diagnosis of sepsis in severely ill patients from a Brazilian hospital

description: Objective To test and validate a multiplex real-time polymerase chain reaction method for bloodstream infections, as well as to compare the results with conventional blood culture.Methods A total of 114 consecutive patients with clinical evidence of sepsis were submitted to blood culture and LightCycler™ SeptiFast tests.Results More positive specimens (23; 20.2%) were detected using the LightCycler™ SeptiFast than the blood culture (17; 14.9%), with an agreement of 86.8%. Discordant results were seen in four patients positive only to blood culture, ten positive only to LightCycler™ SeptiFast and one to different pathogens found by each test. Infections with microorganisms detected only using blood culture reassured the need to perform both tests. The mean time to results for blood culture was 5 days for negative and 3.5 days for positive results. LightCycler™ SeptiFast results were achieved in less than 8 hours.Conclusion LightCycler™ SeptiFast showed a high potential as a test to be carried out concomitantly with blood culture for sepsis diagnosis in severely ill patients. This test allowed a faster diagnosis of bacterial and fungal infections that helped to reduce hospital stay and to control the use of antibiotics. LightCycler™ SeptiFast can also eventually detect microorganism and infections that are hardly detected by blood culture, especiallyCandidanon-albicans infections.
