ABSTRACT
Abstract Objective The present study aims to measure the incidence of overload injuries in training soldiers, who are subjected to intense physical exercise, and to compare it with a control group. Next, it intends to verify whether there is any relationship between overload injuries and some neuromuscular function parameters. Methods Analytical, prospective observational study. Both the observational and the control group consisted of soldiers from the Portuguese Army. Clinical evaluation was performed by medical interview in the week prior to the beginning of a military parachuting course and in the week immediately after its completion. The neuromuscular performance was assessed by isokinetic dynamometry during the medical interview. Results With 44 of the 57 military personnel in training complaining of pain, the observational group had significantly more injuries than the control group (p< 0.001). Five complaints had traumatic origin and 39 were overload injuries. Of the 39 military personnel with overload injuries, 21 reported limited sports performance. However, isokinetic dynamometry showed no statistically significant differences in neuromuscular performance (p = 0.223 and p = 0.229). Conclusion Military personnel in training are prone to overload injuries, with an incidence rate > 70%. The implementation of strategies for injury monitoring and prevention is critical to promote health and physical capacity.
Resumo Objetivo Os autores pretendem medir a incidência de lesões de sobrecarga em militares em formação, que são submetidos a exercício físico intenso, e compará-la com um grupo controle. Posteriormente, pretende-se verificar se existe alguma relação entre a ocorrência de lesões de sobrecarga e alguns parâmetros da função neuromuscular. Métodos Estudo observacional prospectivo analítico. Grupo de observação e grupo controle constituídos por militares do Exército Português. A avaliação clínica foi feita por entrevista médica na semana que antecede o início do curso de paraquedismo militar e na semana imediatamente após o final do curso. Em simultâneo com a entrevista médica, foi realizada a avaliação da performance neuromuscular através da dinamometria isocinética. Resultados Com 44 dos 57 militares em formação a referir queixas álgicas, o grupo de observação apresentou significativamente mais lesões que o grupo controle (p < 0.001). Cinco queixas foram de origem traumática e 39 foram lesões de sobrecarga. Dos 39 militares com lesões de sobrecarga, 21 referiram limitação do rendimento esportivo. No entanto, na avaliação por dinamometria isocinética, não se verificaram diferenças estatisticamente significativas na evolução da performance neuromuscular (p = 0.223 e p = 0.229). Conclusão Os militares em formação são indivíduos propensos a sofrerem lesões de sobrecarga, tendo-se obtido uma taxa de incidência de lesões de sobrecarga na ordem dos 70%. A implementação de estratégias de monitoração e prevenção das lesões são fundamentais na promoção da saúde e da capacidade física.

Introducción: la obesidad en infantes y adolescentes constituye un problema de salud pública en aumento. La resistencia a la insulina es una reducción de respuesta fisiológica de los tejidos diana a la acción de la insulina. Objetivo: determinar el valor de la hipertrigliceridemia e hiperglucemia como marcadores tempranos de resistencia a la insulina en niños y adolescentes obesos. Métodos: el estudio fue de enfoque cuantitativo, diseño no experimental, corte transversal, de tipo observacional y correlacional. La población la constituyeron niños y adolescentes con sobrepeso u obesidad, atendidos en la consulta externa del Hospital Dr. Francisco Icaza Bustamante. Resultados: se demostró la utilidad de parámetros bioquímicos como predictores precoces de insulinorresistencia. El 37,4 por ciento presentó hipertrigliceridemia, 19,8 por ciento hiperglucemia y el 51,6 por ciento insulinorresistencia. El promedio más elevado de triglicéridos fue encontrado en el grupo etario de 6 a 10 años, y en el sexo masculino. El análisis estadístico demostró asociación significativa entre hipertrigliceridemia e insulinorresistencia (p< 0,05). Conclusiones: la hipertrigliceridemia tiene valor predictivo de resistencia a la insulina en obesidad infanto-juvenil(AU)
Introduction: obesity in infants and adolescents is a growing public health problem. Insulin resistance is a reduction in the physiological response of target tissues to the action of insulin. Objective: to determine the value of hypertriglyceridemia and hyperglycemia as early markers of insulin resistance in obese children and adolescents. Methods: the study was of a quantitative approach, non-experimental design, cross sectional, observational and correlational type. The population was constituted by children and adolescents who were overweight or obese, and that were attended in the outpatient clinic of Dr. Francisco Icaza Bustamante Hospital. Results: the usefulness of biochemical parameters as early predictors of insulin resistance was demonstrated. 37.4 percent presented hypertriglyceridemia, 19.8 percent hyperglycemia and 51.6 percent insulin resistance. The highest average of triglycerides was found in the age group of 6 to 10 years, and in the male sex. Statistical analysis showed a significant association among hypertriglyceridemia and insulin resistance (p< 0.05). Conclusions: hypertriglyceridemia has a predictive value of insulin resistance in children-juvenile obesity(AU)

Aims@#Pigments have a large and growing market in the world. Drawbacks in their production such as raw materials availability and low productivity prompt the search for fermentation routes for industrial production. A carotenoid-producing yeast identified as Rhodotorula mucilaginosa was isolated in our laboratory. The aim of this study was to investigate the growth and carotenoid production capacity of the yeast.@*Methodology and results@#A cost-effective substrate of sago starch hydrolysate (SSH) derived from sago fiber waste was used for the fermentation. The fermentation was carried out for 96 h at 27 °C in batch mode. The biomass produced during 5 days of fermentation was 9.6 g/L, which contained a carotenoid concentration of 8.1 mg/L and a specific yield of 845.9 g/g.@*Conclusion, significance and impact of study@#The results demonstrated the capacity of R. mucilaginosa yeast to produce carotenoids and its potential for larger-scale production.
ABSTRACT
Aims@#Bacillus cereus is a Gram-positive, rod-shaped and spore-forming bacterium. It is a ubiquitous bacterium which is widely distributed in several environments such as soil and plants and is commonly isolated from food and its processing environment. This study was aimed to determine the genetic diversity and antibiotic resistance of B. cereus isolated from sago processing in Sarawak. @*Methodology and results@#Out of 120 samples, 42 B. cereus isolates were detected with the presence of hly gene of B. cereus by using specific polymerase chain reaction (PCR). Twenty B. cereus isolates were randomly selected and further characterized by pulsed-field gel electrophoresis (PFGE) of chromosomal DNA digested with NotI to examine the genetic diversity. The result of the PFGE analysis confirmed that the B. cereus strains in sago processing were genetically diverse. Based on the dendrogram generated, B. cereus strains were grouped into two major clusters and these clusters were grouped together based on sources of isolation. The investigation on the antibiotic resistance of B. cereus strains revealed that the B. cereus strains were uniformly highly resistant to penicillin and ampicillin and highly susceptible to imipenem and norfloxacin. @*Conclusion, significance and impact of study@#The results of this study suggest that the B. cereus isolated from sago processing derived from a mixture of sensitive and resistant strains with diverse genetic contents.
ABSTRACT
A impactação dentária é um distúrbio de erupção e, por conseqüência, um dos problemas ortodônticos observados na rotina clínica. O tratamento usualmente envolve o desafio de procedimentos cirúrgicos, ortodônticos e periodontais. Um bom diagnóstico do caso dependerá do diagnóstico precoce e da avaliação da posição e angulação dentária no alvéolo, dentre outros fatores. A apresentação deste caso clínico relata a importância do dente 21, devido a uma grave dilaceração de raiz, diagnosticada por meio de uma tomografia linear. O tratamento proposto combinou a expansão do arco superior, a técnica cirúrgica e de erupção fechada e a tração ortodôntica, além da aplicação de aparelhagem ortodôntica fixa, para o correto alinhamento do dente. Os procedimentos permitiram restabelecer com sucesso a estética e a oclusão do paciente
