    Justificativa e Objetivos: no Brasil, infecções de sítio cirúrgico (ISC) compreendem aproximadamente 15% das infecções relacionadas à assistência à saúde (IRAS). Este estudo avaliou a dinâmica das infecções por meio da metodologia tracer, alinhada à análise por redes complexas, utilizando o rastreamento de um paciente (caso) que foi submetido à cirurgia (cenário). Métodos: estudo de caso, de natureza observacional, abordagem descritiva, com avaliação transversal e retrospectiva, pelo rastreamento e análise do prontuário de um paciente submetido a procedimentos cirúrgicos, utilizando a metodologia tracer, sob a ótica das redes complexas, no Hospital das Clínicas, Universidade Federal de Pernambuco. Resultados: mulher, 65 anos, submetida à descompressão, artrodese e retirada de enxerto (doador) em ilíaco esquerdo. Readmitida com osteomielite do ilíaco esquerdo, evoluindo com piora do estado geral, seguido de óbito. O fator de prioridade (PFP) relacionado ao caso foi o procedimento cirúrgico para retirada do enxerto no ilíaco esquerdo pela clínica ortopédica. De acordo com o Manual Brasileiro de Acreditação Hospitalar, os padrões obrigatórios e aplicáveis, segundo o perfil do hospital, apresentam os seguintes percentuais de conformidade para o nível 1 (78,7%), nível 2(82,4%) e no nível 3 (51,7%). Utilizando as redes complexas e considerando que os profissionais são potenciais carreadores da disseminação das infecções aos suscetíveis e são preditores da propagação da ISC (cenário 2/hipótese 2), somado à falta de estrutura para higienização das mãos (cenário 3/hipótese 3), observou-se que há maior chance de ISC ter ocorrido nos setores da enfermaria e UTI. Conclusões: a provável propagação das IRAS está relacionada aos profissionais e à estrutura físico-funcional necessária para prestação da assistência segura

    The process of storing liquor in wooden barrels is a practice that aims to improve the sensory characteristics, such as color, aroma and flavor, of the beverage. The quality of the liquor stored in these barrels depends on wood characteristics such as density, permeability, chemical composition, anatomy, besides the wood heat treatment used to fabricate the barrels. Brazil has a great diversity of forests, mainly in the north, in the Amazon. This region is home to thousands of tree species, but is limited to the use of only a few native species to store liquors. The objective of this study was to determine some of the physical and chemical characteristics for four Amazon wood species. The results obtained in this study will be compared with others from woods that are traditionally used for liquor storage. The species studied were angelim-pedra (Hymenolobium petraeum Ducke) cumarurana (Dipteryx polyphylla (Huber) Ducke), jatobá (Hymenaea courbaril L.) and louro-vermelho (Nectandra rubra (Mez) CK Allen). The trees were collected from Precious Woods Amazon Company forest management area, in Silves, Amazonas. Analyzes such as: concentration of extractives, lignin amount, percentage of minerals (ash) and tannin content, density, elemental analysis (CHNS-O) and thermal analysis were done. It was observed that the chemical composition (lignin, holocellulose) and elemental analysis (percentage of C, H, N and O) of the woods have significant differences. The jatobá wood presented higher tannin content, and in the thermal analysis, was that which had the lowest mass loss. © 2015, Federal University of Lavras. All rights Reserved

    BACKGROUND: It is increasingly recognized that treating pain is crucial for effective care within neurological rehabilitation in the setting of the neurological rehabilitation. The Italian Consensus Conference on Pain in Neurorehabilitation was constituted with the purpose identifying best practices for us in this context. Along with drug therapies and physical interventions, psychological treatments have been proven to be some of the most valuable tools that can be used within a multidisciplinary approach for fostering a reduction in pain intensity. However, there is a need to elucidate what forms of psychotherapy could be effectively matched with the specific pathologies that are typically addressed by neurorehabilitation teams. OBJECTIVES: To extensively assess the available evidence which supports the use of psychological therapies for pain reduction in neurological diseases. METHODS: A systematic review of the studies evaluating the effect of psychotherapies on pain intensity in neurological disorders was performed through an electronic search using PUBMED, EMBASE, and the Cochrane Database of Systematic Reviews. Based on the level of evidence of the included studies, recommendations were outlined separately for the different conditions. RESULTS: The literature search yielded 2352 results and the final database included 400 articles. The overall strength of the recommendations was medium/low. The different forms of psychological interventions, including Cognitive-Behavioral Therapy, cognitive or behavioral techniques, Mindfulness, hypnosis, Acceptance and Commitment Therapy (ACT), Brief Interpersonal Therapy, virtual reality interventions, various forms of biofeedback and mirror therapy were found to be effective for pain reduction in pathologies such as musculoskeletal pain, fibromyalgia, Complex Regional Pain Syndrome, Central Post-Stroke pain, Phantom Limb Pain, pain secondary to Spinal Cord Injury, multiple sclerosis and other debilitating syndromes, diabetic neuropathy, Medically Unexplained Symptoms, migraine and headache. CONCLUSIONS: Psychological interventions and psychotherapies are safe and effective treatments that can be used within an integrated approach for patients undergoing neurological rehabilitation for pain. The different interventions can be specifically selected depending on the disease being treated. A table of evidence and recommendations from the Italian Consensus Conference on Pain in Neurorehabilitation is also provided in the final part of the pape

    FOOT: a new experiment to measure nuclear fragmentation at intermediate energies

    Summary: Charged particle therapy exploits proton or 12C beams to treat deep-seated solid tumors. Due to the advantageous characteristics of charged particles energy deposition in matter, the maximum of the dose is released to the tumor at the end of the beam range, in the Bragg peak region. However, the beam nuclear interactions with the patient tissues induces fragmentation both of projectile and target nuclei and needs to be carefully taken into account. In proton treatments, target fragmentation produces low energy, short range fragments along all the beam range, which deposit a non negligible dose in the entry channel. In 12C treatments the main concern is represented by long range fragments due to beam fragmentation that release their dose in the healthy tissues beyond the tumor. The FOOT experiment (FragmentatiOn Of Target) of INFN is designed to study these processes, in order to improve the nuclear fragmentation description in next generation Treatment Planning Systems and the treatment plans quality. Target (16O and 12C nuclei) fragmentation induced by –proton beams at therapeutic energies will be studied via an inverse kinematic approach, where 16O and 12C therapeutic beams impinge on graphite and hydrocarbon targets to provide the nuclear fragmentation cross section on hydrogen. Projectile fragmentation of 16O and 12C beams will be explored as well. The FOOT detector includes a magnetic spectrometer for the fragments momentum measurement, a plastic scintillator for ΔE and time of flight measurements and a crystal calorimeter to measure the fragments kinetic energy. These measurements will be combined in order to make an accurate fragment charge and isotopic identification. Keywords: Hadrontherapy, Nuclear fragmentation cross sections, Tracking detectors, Scintillating detector

    What is the role of the placebo effect for pain relief in neurorehabilitation? Clinical implications from the Italian consensus conference on pain in neurorehabilitation

    Background: It is increasingly acknowledged that the outcomes of medical treatments are influenced by the context of the clinical encounter through the mechanisms of the placebo effect. The phenomenon of placebo analgesia might be exploited to maximize the efficacy of neurorehabilitation treatments. Since its intensity varies across neurological disorders, the Italian Consensus Conference on Pain in Neurorehabilitation (ICCP) summarized the studies on this field to provide guidance on its use. Methods: A review of the existing reviews and meta-analyses was performed to assess the magnitude of the placebo effect in disorders that may undergo neurorehabilitation treatment. The search was performed on Pubmed using placebo, pain, and the names of neurological disorders as keywords. Methodological quality was assessed using a pre-existing checklist. Data about the magnitude of the placebo effect were extracted from the included reviews and were commented in a narrative form. Results: 11 articles were included in this review. Placebo treatments showed weak effects in central neuropathic pain (pain reduction from 0.44 to 0.66 on a 0-10 scale) and moderate effects in postherpetic neuralgia (1.16), in diabetic peripheral neuropathy (1.45), and in pain associated to HIV (1.82). Moderate effects were also found on pain due to fibromyalgia and migraine; only weak short-term effects were found in complex regional pain syndrome. Confounding variables might have influenced these results. Clinical implications: These estimates should be interpreted with caution, but underscore that the placebo effect can be exploited in neurorehabilitation programs. It is not necessary to conceal its use from the patient. Knowledge of placebo mechanisms can be used to shape the doctor-patient relationship, to reduce the use of analgesic drugs and to train the patient to become an active agent of the therapy

    Measuring the cosmic ray flux over timescales comparable to the age of the solar system, 4.5\sim 4.5\,Gyr, could provide a new window on the history of the Earth, the solar system, and even our galaxy. We present a technique to indirectly measure the rate of cosmic rays as a function of time using the imprints of atmospheric neutrinos in paleo-detectors, natural minerals which record damage tracks from nuclear recoils. Minerals commonly found on Earth are 1\lesssim 1\,Gyr old, providing the ability to look back across cosmic ray history on timescales of the same order as the age of the solar system. Given a collection of differently aged samples dated with reasonable accuracy, this technique is particularly well-suited to measuring historical changes in the cosmic ray flux at Earth and is broadly applicable in astrophysics and geophysics.Measuring the cosmic ray flux over timescales comparable to the age of the Solar System, ∼4.5  Gyr, could provide a new window on the history of the Earth, the Solar System, and even our Galaxy.

    The use of exergame for balance competencies was recently explored in women affected by balance ability reduction with non-conclusive results. The aim of the study was to evaluate the efficacy of a supervised exergame performed with the Wii Fit® compared to conventional exercises on balance function, quality of life, fear of fall and well-being in women with bone loss. Thirty-eight female participants aged over 65 years, with a bone loss condition, were enrolled and random allocated in the Wii group or control group. Subject enrolled in Wii group performed a balance training with a Wii Fit supervised by a physiotherapist (1 h, 2 days per week, during 8 weeks) while in control subjects performed the same amount of conventional balance exercises. Subject enrolled in experimental group showed significantly higher scores in terms of Berg Balance Scale (p = 0.027). In SF-36 scores, a significant difference was reported for physical activity score after treatment (p = 0.031). Fear of falling and the psychological scales were not significantly different between the two groups. In women with bone loss condition, a supervised Wii Fit training has shown better efficacy in improving balance performance with respect to conventional balance exercises
