Infrared Thermography as a Predictor of Inflammatory Response in the Elderly with Arthritis

Research article of International Research Journal of Optics and Photonics Infrared Thermography as a Predictor of Inflammatory Response in the Elderly with Arthritis Madruga, M.L.L.H1; Melo, G.A2; Martins, M.L3; Aranha, R.E.L.B4; Marinho, J.S5; Alves, N.T6 1Estudante de Fisioterapia – UFPB; 2,3,4Mestranda em Neurociência Cognitiva e Comportamento – UFPB, 5Estudante de Engenharia de Produção – UFPB, 6Docente/Pesquisador do Departamento de Psicologia – UFPB. Among the physiological responses associated with osteoarthritis, the increase in muscle and epithelial temperature is an indicator of pro-inflammatory status. However, however, the association between epithelial temperature increase and osteoarthritis in elderly individuals was not yet measured. Therefore, the objective of the study was to investigate whether the thermographic pattern is able to predict the inflammatory in lower limbs in individuals with osteoarthritis. The sample consisted of 10 participants with arthritis separated by men (MW: 2; age: 75 ± 10.2 years; body mass: 78.5 ± 12.2 kg; height: 164.5 ± 8.6 cm) and women (FW: 8, age: 75 ± 10.2 years, body mass: 69.1 ± 9.5 kg, height: 153.6 ± 9.9 cm). Infrared thermography (FLIR® thermography) was performed in 6 regions of interest (IR) in the coronal (anterior and posterior) and sagittal (left and right portions) planes. To obtain predictive models, regression analyzes were performed for both sexes, p≤0.05. The results indicated that the presence of inflammation could be predicted by the following models for men: RI Posterior thigh (Exp (B) = 3.023 95% C.I. = 1.065 to 8.578, S.E = 0.532, Wald = 4.331, p = 0.038). While women showed two predictive IRs in the first model, calf thermography (Exp (B) = 3.8442 95% CI = 0.167 to 1.00, SE = 0.457, Wald = 3.84, p = 0.050) and, in the second model, the left anterior calf (Exp (B) = 6.211 95% CI = 1.447 to 21.976, SE ...

Eletroencephalographic study of individuals with chronic pain during fibromyalgia

Review article of International Research Journal of Optics and Photonics Eletroencephalographic study of individuals with chronic pain during fibromyalgia Madruga, M.L.L.H1; Melo, G.A2; Martins, M.L3; Aranha, R.E.L.B4; Marinho, J.S5; Alves, N.T6 1Estudante de Fisioterapia – UFPB; 2,3,4Mestranda em Neurociência Cognitiva e Comportamento – UFPB, 5Estudante de Engenharia de Produção – UFPB, 6Docente/Pesquisador do Departamento de Psicologia – UFPB. Introduction: Fibromyalgia is a syndrome that is mainly featured by the chronic pain presence and its phisiophatology is unknown. In the EEG records it is observed a hipersensibility from the envolved areas at the pain process, which can be a resource capable to clarify its phisiophatology. Objective: It was performed a search at Pubmed, Lilacs e Scielo databases with the keywords: Electroencephalogram, electroencephalography and fibromyalgia. The exclusion criterias were the electroencephalogram use for avaliation of other clinic condition beyond fibromyalgia and repeated articles at the databases. Results: After the aplication of the eligibility criterias were found 23 articles. Conclusion: The electrical cortical activity analysis using the electroencephalogram records is set like a promising method of avaliation and identification of a fibromyalgia biomarker.

Cerebrospinal fluid analysis of patients with als by x-ray microfluorescence

Research article of International Research Journal of Optics and Photonics Cerebrospinal fluid analysis of patients with als by x-ray microfluorescence Silva, J.P.R1; Mendonça, D.M.F2; Barbosa, R.F3; Jesus, E.F.O4; Chimelli, L5; Martinez, A.M.B6 1Physiotherapy Student, UFS, 2Professor, Researcher at the Biosciences Department, UFS; 3Professor, Researcher at the Physics Institute, USP; 4Professor, researcher at the Nuclear Engineering Department, UFRJ; 5Researcher at the Brain Institute of Rio de Janeiro; 6Professor, Researcher at Biomedical Sciences Institute, UFRJ. Introduction: Amyotrophic Lateral Sclerosis (ALS) is the most common motor neuron disease in adults but its etiology remains unknown. Clinically, the patient manifests progressive weakness, paralysis and, usually, evolves to death between 2 to 5 years. The analysis of biological samples provides a powerful strategy to investigate pathological processes and studies indicate an important role of trace elements in ALS. Objective: In this work we aimed to investigate the levels of trace elements in CSF samples from patients with ALS. Methodology: CSF samples from cases of ALS (10) and control cases (6) were treated for analysis of trace elements by X-ray Microfluorescence with Synchrotron Radiation. The measurements were performed on the XRF beam line at the National Synchrotron Light Laboratory (Campinas, Brazil). The intensity of the X-ray spectrum for each element was obtained with AXIL software (distributed by the International Atomic Energy Agency). The data obtained were statistically analyzed by General Linear Models, in a method based on multivariate analysis. Results and Discussion: In this study, the following elements were analyzed: aluminum, bromine, calcium, chlorine, copper, chromium, iron, potassium, phosphorus, nickel, rubidium, silicon, sulfur and zinc. In CSF samples from ALS cases a significant increase of calcium, chlorine and potassium concentration was observed when compared to samples from control cases. Conclusion: Excitotoxicity is one of the many factors implicated in the pathogenic process of ALS. The intracellular calcium ...
