Lombalgia ocupacional e a postura sentada: efeitos da cinesioterapia laboral

Abstract: JUSTIFICATIVA E OBJETIVOS: A lombalgia e apresentada como a mais frequente afeccao da coluna vertebral, provocando desde limitacao de movimento ate invalidez temporaria. Estudos revelam etiologia multifatorial, destacando-se as causas biomecânicas, as caracteristicas individuais e os fatores ocupacionais. O presente estudo teve como objetivo verificar os efeitos da cinesioterapia em pacientes portadores de lombalgia ocupacional. METODO: Trinta e oito funcionarios de uma instituicao de ensino superior da cidade de Recife portadores de lombalgia ocupacional, que trabalhavam sentados, foram avaliados por meio da Escala de Dor Autopercebida, dos questionarios funcionais de Oswestry e Roland-Morris e do teste de avaliacao fisica Screening antes e apos sessoes de cinesioterapia laboral. RESULTADOS: Houve melhora estatisticamente significante na intensidade da dor avaliada pela Escala de Dor Autopercebida (p < 0,001) e no teste de avaliacao fisica Screening (p = 0,001). Entretanto, nao houve melhora significativa pela analise dos questionarios de Oswestry e Roland-Morris. CONCLUSAO: Os resultados permitem inferir que a cinesioterapia laboral melhorou a dor lombar, diminuindo a sua intensidade, melhorando a capacidade funcional dos musculos estabilizadores do tronco e a amplitude de movimento articular.

Influence of helmet use in facial trauma and moderate traumatic brain injury victims of motorcycle accidents.

Abstract: OBJECTIVE: The objective of this research was to study the influence of the use of helmet in facial trauma victims of motorcycle accidents with moderate traumatic brain injury. METHODS: We retrospectively reviewed the incidence of facial injuries in helmeted and nonhelmeted victims with moderate traumatic brain injury at a referral trauma hospital. RESULTS: The sample consisted of 272 patients predominantly men (94.5%) and between 21 and 40 years old (62.9%). The majority of patients were using helmet (80.1%). The occurrence of facial fractures was most frequent for zygomatic bone (51.8%), followed by mandible (18.8%) and nasal bones (9.2%). CONCLUSIONS: Individuals in the most productive age group are most affected, which causes a great loss to financial and labor systems. It is important to take measures to alert the public regarding the severity of injuries likely to occur in motorcycle-related accidents and ways to prevent them. Language: en

Characterization of Software Aging Effects in Elastic Storage Mechanisms for Private Clouds

Abstract: Cloud computing systems fundamentally provide access to large pools of data and computational resources. Eucalyptus is a software framework used to implement private and hybrid-style Infrastructure as a Service clouds. It implements the Amazon Web Service (AWS) API, allowing interoperability with other AWS-based services. Elastic block storage (EBS) is a technology which provides flexible allocation of remote storage volumes to the virtual machines running in a cloud computing environment. Eucalyptus interacts with many software components to provide EBS features to the virtual machines: KVM hypervisor and Eucalyptus Node Controller (NC) are among those components. This work investigates the software aging effects in a Eucalyptus environment, considering workloads composed of intensive requests for attaching remote storage volumes to virtual machines. The results evidenced that memory leaks in Node Controller and the high CPU utilization by the KVM process are strongly correlated. The experimental analysis also show how much the aging effects are related to the performance degradation of a virtualized web server running on this infrastructure.

Hemodynamic Changes Comparing 2% Lidocaine and 4% Articaine With Epinephrine 1: 100,000 in Lower Third Molar Surgery

Abstract: BackgroundAn increase in blood pressure during dental treatment has been investigated with regard to potential medical risks since previous studies suggest that dental procedures may cause stress to the patient and, consequently, the cardiovascular system. The aim of the present study was to analyze

Antimicrobial activity of silver nanoparticle colloids of different sizes and shapes against Streptococcus mutans

Abstract: Silver nanoparticles stabilized with chitosan biopolymer are a new antibacterial agent for treatment of caries To determine whether the size and morphology of silver nanoparticles in colloidal solution altered their antimicrobial activity, four colored colloids were characterized by ultraviolet–visible (UV–Vis) spectroscopy and transmission electron microscopy (TEM), and their antimicrobial activity [minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC)] against reference stocks of Streptococcus mutans ATCC 25175 compared with chlorhexidine and silver diamine fluoride as controls TEM revealed that the seed solution (SS) contained only spherical nanoparticles with size of 87 ± 31 nm whereas the other colloids had predominantly spherical nanoparticle shape, although colloid 1 (S1) contained 25% triangular nanoparticles Colloid 2 (S2) had 159% triangular and 68% cylindrical nanoparticles, while 233% of the silver nanoparticles in colloid 3 (S3) were triangular and 15% were cylindrical All the silver nanoparticle colloids showed antimicrobial activity with no statistically significant differences (p > 005) in MIC or MBC The colloids showed antimicrobial activity higher than silver diamine fluoride (p 005) The size and shape of the nanoparticles did not affect the antimicrobial properties of the colored colloids Thus, the antimicrobial activity of the colloids containing silver nanoparticles against Streptococcus mutans was considered equivalent to that of chlorhexidine, the gold-standard antibiotic in dentistry
