Segurança no trabalho de aplicação de agrotóxicos com o pulverizador de pistolas em citros

The purpose of this study envisaged the quantification of skin and respiratory exposures occasioned by work conditions during pesticide spraying of citrus fruits using hand gun sprayers; the evaluation of the efficiency of individual and group protection measures for the workers; the determination of workers' most exposed body regions; and the classification of work conditions, with and without the tested work-safety protection measures as recommended for the registered pesticides used to control the main pests and diseases that attack these types of trees and fruits. The AZR protection equipment proved to be the most efficient for the tractor driver, when spraying using pistol sprayers. The two sets of individual protection equipment that were checked also proved to be efficient. The most exposed regions of the tractor driver's body were the thighs, the front of the legs, the feet and hands. The most exposed regions of the individual sprayer working on foot were the hands and feet.

Segurança no trabalho com agrotóxicos em citros: aplicação com o turbopulverizador e preparo de calda em tanque de 2.000 L

The objectives of this study were: a) to quantify dermal and respiratory exposure resulting from work conditions in the application of pesticides on citrus crops using a air-assisted sprayer and by preparing the spray in a tank with a capacity of2.000 L; b) to evaluate the measures of individual protection for these workers; c) to determine the areas of the worker's body most exposed; and d) to classify the work conditions with and without the protective measures tested, with regard to the occupational safety of the recommendations for the pesticides used in controlling the main pests and diseases of this crop. It was shown that for the tractor driver and sprayer operator applyng pesticides on citrus trees, the most efficient protective measures were the AZR ensemble and the Real cabin. The AZR ensemble was effective in controlling exposure of the spray preparer, because it was sufficient to turn work conditions from unsafe to safe. The area of the body most exposed under the two work conditions studied was the hands of the workers.

Aplicação materna de glicocorticoide nos parâmetros vitais de cordeiros nascidos a termo e prematuros

The aim of the study was to evaluate the influence of glucocorticoids on vital parameters of full-term and preterm lambs from birth to 48 hours of life. Four experimental groups were formed: NDG (normal delivery group - lambs vaginally delivered, n=15, average of 146-day gestation); NDEXG (normal delivery with dexamethasone group - lambs vaginally delivered whose mothers received 16mg of dexamethasone at 141 days of gestation, n=8, average of 143-day gestation); PRE (premature lambs born by cesarean section at 138 days of gestation, n=10) and PREDEX (premature lambs born by cesarean section at 138 days gestation, whose mothers received 16mg of dexamethasone two days before, n=9). Heart and respiratory rates had variations during the observation period, with the highest mean values in the groups of normal deliveries (NDG and NDEXG). Rectal temperature decreased in all groups in the first 60 minutes of life, with the lowest mean values in premature lambs (PRE and PREDEX) and the Apgar score was higher in animals delivered at normal gestational time. Preterm lambs had lower vitality and chance of survival, however, lower mortality rate was observed in offspring of ewes that received dexamethasone two days before surgery.

Neurophysiological aspects of musical auditory stimulation on cardiovascular system

Introduction: The literature has shown that musical stimulation can influence the cardiovascular system, however, the neurophysiological aspects of this influence are not yet fully elucidated. Objective: This study describes the influence of music on the neurophysiological mechanisms in the human body, specifically the variable blood pressure, as well as the neural mechanisms of music processing. Methods: Searches were conducted in Medline, PEDro, Lilacs and SciELO using the intersection of the keyword “music” with the keyword descriptors “blood pressure” and “neurophysiology”. Results: There were selected 11 articles, which indicated that music interferes in some aspects of physiological variables. Conclusion: Studies have indicated that music interferes on the control of blood pressure, heart and respiratory rate, through possible involvement of limbic brain areas which modulate hypothalamic-pituitary functions. Further studies are needed in order to identify the mechanisms by which this influence occurs.

Influência do estímulo verbal no tempo do teste de escada

Introduction: The stair-climbing test (SCT) is considered a submaximal test of simple implementation and easy access, which assesses the individual’s functional capacity. Although widely used in surgical patients, there is no standardization regarding the height of the stair and verbal stimulus. Objectives: It was determine if verbal stimulus changes the stair-climbing time (SCt) in individuals over 50 years-old. We compared oxygenation, blood pressure, pulse, respiratory rate and Borg scale between SCT performed with and without stimulation. Methods: We evaluated individuals with ages greater than 50 years-old that performed two STC (with and without verbal stimulation), in the stair with 44 steps, achieving 7.04 m in height and recording the time to climb the stair. The systolic blood pressure (SBP) and the diastolic blood pressure (DBP), respiratory rate (RR), pulse, oxygen saturation (SpO2 ) and Borg scale were evaluated before and after the tests. The time in the SCT with and without stimulation were compared using the Student test-t and the other variables were compared using the ANOVA test (p<0.05). Results: The average age was 59.75±6,40 years old in the 21 evaluated individuals. The time in the SCT without stimulus was significantly higher than the one with stimulus. The SBP, pulse, RR and Borg scale were significantly increased when compared to the SCT with and without stimulus. Oxygenation and DBP didn´t have significant differences at any time of the study. Conclusions: The time in the SCT was lower when performed with verbal stimulus. The SBP, pulse, RR and Borg scale changed significantly after the SCT with and without stimulus, remarking that this change was greater in the SCT with stimulus.
