Sodium Channel–Dependent and –Independent Mechanisms Underlying Axonal Afterdepolarization at Mouse Hippocampal Mossy Fibers
Authors: Ohura Shunsuke , Kamiya Haruyuki
Published: August 2018

Action potentials propagating along axons are often followed by prolonged afterdepolarization (ADP) lasting for several tens of milliseconds. Axonal ADP is thought to be an important factor in modulating the fidelity of spike propagation during repetitive firings. However, the mechanism as well as the functional significance of axonal ADP remain unclear, partly due to inaccessibility to small structures of axon for direct electrophysiological recordings. Here, we examined the ionic and electrical mechanisms underlying axonal ADP using whole-bouton recording from mossy fiber terminals in mice hippocampal slices. ADP following axonal action potentials was strongly enhanced by focal application of veratridine, an inhibitor of Na+channel inactivation. In contrast, tetrodotoxin (TTX) partly suppressed ADP, suggesting that a Na+channel–dependent component is involved in axonal ADP. The remaining TTX-resistant Na+channel–independent component represents slow capacitive discharge reflecting the shape and electrical properties of the axonal membrane. We also addressed the functional impact of axonal ADP on presynaptic function. In paired-pulse stimuli, we found that axonal ADP minimally affected the peak height of subsequent action potentials, although the rising phase of action potentials was slightly slowed, possibly due to steady-state inactivation of Na+channels by prolonged depolarization. Voltage clamp analysis of Ca2+current elicited by action potential waveform commands revealed that axonal ADP assists short-term facilitation of Ca2+entry into the presynaptic terminals. Taken together, these data show that axonal ADP maintains reliable firing during repetitive stimuli and plays important roles in the fine-tuning of short-term plasticity of transmitter release by modulating Ca2+entry into presynaptic terminals.
Neurotransmitter- and Release-Mode-Specific Modulation of Inhibitory Transmission by Group I Metabotropic Glutamate Receptors in Central Auditory Neurons of the Mouse
Authors: Curry Rebecca J. , Peng Kang , Lu Yong
Published: August 2018

Neuromodulation mediated by metabotropic glutamate receptors (mGluRs) regulates many brain functions. However, the functions of mGluRs in the auditory system under normal and diseased states are not well understood. The medial nucleus of the trapezoid body (MNTB) is a critical nucleus in the auditory brainstem nuclei involved in sound localization. In addition to the classical calyx excitatory inputs, MNTB neurons also receive synaptic inhibition and it remains entirely unknown how this inhibition is regulated. Here, using whole-cell voltage clamp in brain slices, we investigated group I mGluR (mGluR I)-mediated modulation of the glycinergic and GABAergic inputs to MNTB neurons in both WT mice and a fragile X syndrome (FXS) mouse model (both sexes) in which the fragile X mental retardation gene 1 is knocked out (Fmr1KO), causing exaggerated activity of mGluR I and behavioral phenotypes. Activation of mGluR I by (RS)-3,5-dihydroxyphenylglycine (3,5-DHPG) increased the frequency and amplitude of glycinergic spontaneous IPSCs (sIPSCs) in both WT andFmr1KO neurons in a voltage-gated sodium channel-dependent fashion, but did not modulate glycinergic evoked IPSCs (eIPSCs). In contrast, 3,5-DHPG did not affect GABAergic sIPSCs, but did suppress eIPSCs in WT neurons via endocannabinoid signaling. In the KO, the effect of 3,5-DHPG on GABAergic eIPSCs was highly variable, which supports the notion of impaired GABAergic signaling in the FXS model. The differential modulation of sIPSC and eIPSC and differential modulation of glycinergic and GABAergic transmission suggest distinct mechanisms responsible for spontaneous and evoked release of inhibitory transmitters and their modulation through the mGluR I signaling pathway.

SIGNIFICANCE STATEMENTNeurons communicate with each other through the release of neurotransmitters, which assumes two basic modes, spontaneous and evoked release. These two release modes are believed to function using the same vesicle pool and machinery. Recent works have challenged this dogma, pointing to distinct vesicle release mechanisms underlying the two release modes. Here, we provide the first evidence in the central auditory system supporting this novel concept. We discovered neural-transmitter- and release-mode-specific neuromodulation of inhibitory transmission by metabotropic glutamate receptors and revealed part of the signaling pathways underlying this differential modulation. The results establish the foundation for a multitude of directions to study physiological significance of different release modes in auditory processing.

Published: August 2018

α-Synuclein (αsyn) is the key protein that forms neuronal aggregates in the neurodegenerative disorders Parkinson's disease (PD) and dementia with Lewy bodies. Recent evidence points to the prion-like spread of αsyn from one brain region to another. Propagation of αsyn is likely dependent on release, uptake, and misfolding. Under normal circumstances, this highly expressed brain protein functions normally without promoting pathology, yet the underlying endogenous mechanisms that prevent αsyn spread are not understood. 14-3-3 proteins are highly expressed brain proteins that have chaperone function and regulate protein trafficking. In this study, we investigated the potential role of the 14-3-3 proteins in the regulation of αsyn spread using two models of αsyn spread. In a paracrine αsyn model, 14-3-3θ promoted release of αsyn complexed with 14-3-3θ. Despite higher amounts of released αsyn, extracellular αsyn showed reduced oligomerization and seeding capability, reduced internalization, and reduced toxicity in primary mixed-gender mouse neurons. 14-3-3 inhibition reduced the amount of αsyn released, yet released αsyn was more toxic and demonstrated increased oligomerization, seeding capability, and internalization. In the preformed fibril model, 14-3-3 θ reduced αsyn aggregation and neuronal death, whereas 14-3-3 inhibition enhanced αsyn aggregation and neuronal death in primary mouse neurons. 14-3-3s blocked αsyn spread to distal chamber neurons not exposed directly to fibrils in multichamber, microfluidic devices. These findings point to 14-3-3s as a direct regulator of αsyn propagation, and suggest that dysfunction of 14-3-3 function may promote αsyn pathology in PD and related synucleinopathies.

SIGNIFICANCE STATEMENTTransfer of misfolded aggregates of α-synuclein from one brain region to another is implicated in the pathogenesis of Parkinson's disease and other synucleinopathies. This process is dependent on active release, internalization, and misfolding of α-synuclein. 14-3-3 proteins are highly expressed chaperone proteins that interact with α-synuclein and regulate protein trafficking. We used two different models in which toxicity is associated with cell-to-cell transfer of α-synuclein to test whether 14-3-3s impact α-synuclein toxicity. We demonstrate that 14-3-3θ reduces α-synuclein transfer and toxicity by inhibiting oligomerization, seeding capability, and internalization of α-synuclein, whereas 14-3-3 inhibition accelerates the transfer and toxicity of α-synuclein in these models. Dysfunction of 14-3-3 function may be a critical mechanism by which α-synuclein propagation occurs in disease.

Published: August 2018

In this work, steganography is implemented in photographs captured by an unmanned aerial vehicle (drone), with the purpose of adding an identifier that indicates which device they are taken from so it works for the recovery of the origin. In the system, a new technique that modifies the least significant bit (LSB) is applied, using a mathematical model to generate the chaotic orbits, one of the parts selects the RGB channel (Red, Green or Blue) where the LSB is changed and the other is implemented to calculate the random position of the sub pixel to be modified in the selected channel. In addition, a comparison between the bit to be hidden and the LSB of the pixel of the image is performed to verify if it is not necessary to modify it, which lessens the alterations in the container image. It is a tool to capture photos remotely with the Ar.Drone 2.0, with the features needed to perform an analysis that uses correlation diagrams and histograms to verify if the integrity of the message is guaranteed or if changes in the stego-image are visible to the naked eye. On the other hand, a test was done on the Baboon image to compare the robustness of the proposed system with other investigations, evaluating the correlation, contrast, energy, homogeneity, MSE, PSNR and quality index. The results generated were compared with the work of other authors concluding our system provides greater security, integrity, high sensitivity to the keys, it is not linked to a single chaotic system and can be applied to hide imperceptibly all kinds of information, in: radiographs, videos, files, official documents, and other types of containers.

Published: August 2018

One of the main challenges in Macroergonomics is to develop a universal model to measure macroergonomic compatibility. As a first step to develop such model, it is necessary to validate the construct of macroergonomic compatibility (MC). MC refers to the ability of the different work system components and elements to complement the capabilities and limitations of employees in order to achieve companies’ goals. In that regard, to achieve this step, this paper analyzes the effects of MC of physical and psychological characteristics of employees over the performance of manufacturing systems measured by the clients, production processes, and the organizational performance of companies. Data was obtained from 188 employees of manufacturing systems by means of the Macroergonomic Compatibility Questionnaire (MCQ) in Chihuahua, Mexico. Also, data is analyzed to propose and test a hypothetical causal model of the relationships among the variables by using a Structural Equation Modeling (SEM) approach. Employees’ physical characteristics (weight, height, strength) are considered as independent variable. The highest direct effects values (ß) were found from physical characteristics to psychological characteristics (0,49), from clients to organizational performance (0,45), and from psychological characteristics to motivation and needs. Also, the highest total effects were found from physical characteristics to motivation and needs (0,517) and psychological characteristics (0,488) and from clients to organizational performance (0,454). Results of this model offer relevant knowledge to develop macroergonomic strategies for manufacturing systems in order to increase their competitiveness and support the design and improvement of these systems.

Authors: Mendonça Fausto , Urgessa Girum , Rocco José
Published: August 2018

This paper presents results from blast tests conducted on four 50 MPa concrete slabs with reinforcement ratios of 0,175% and 0,37%. Two of the slabs were retrofitted with 50 mm thick foam in order to investigate the potential of using the foam as a strengthening option. The slabs were simply supported on two sides. Non-confined PBX (Plastic bonded explosive) was molded with the form of a cylinder measuring 20 cm in height and 10,5 cm in diameter. The explosive was detonated at 2 m stand-off distance. The equivalent TNT mass of the explosive ranges from 2,58 to 2,72 kg for the four tests. Accelerometers, displacement and pressure gages were used to measure blast wave parameters and global response of the slabs. A high-speed digital camera in conjunction with a rugged notebook recorded images. Qualitative and quantitative results are included. Slabs retrofitted with foam showed a different pressure pattern as recorded by the sensors and resulted in higher displacement, acceleration and linear momentum.

Published: August 2018

The effect of the pulse current, pulse on time and pulse off time on the surface roughness of AISI 304 stainless steel workpieces produced by electric discharge machining (EDM) using grade GSP-70 graphite electrodes was studied. A factorial design was performed, considering two levels for each of the three established parameters. From the statistical analysis, it was obtained that the pulse current and pulse on time are the most significant machining parameters on the obtained surface roughness values of the stainless steel AISI 304 workpieces machined by EDM. On the other hand, the regression analysis of a second order model was done to estimate the average roughness (Ra) in terms of the pulse current, pulse on time and pulse off time. Finally, the mean absolute percentage error (MAPE) of the roughness values estimated by the second order regression model and the roughness obtained experimentally is also presented.

Published: August 2018

The purpose of this research is to apply a new approach to make a fast determination of earthquake depth using seismic records of the “El Rosal” station, near to the city of Bogota – Colombia, by applying support vector machine regression (SVMR). The algorithm was trained with descriptors obtained from time signals of 863 seismic events acquired between January 1998 and October 2008; only earthquakes with magnitude ≥ 2 were contemplated, filtering its signals to remove diverse kind of noises not related to earth tremors. During training stages of SVMR several combinations of kernel function exponent and complexity factor were considered for time signals of 5, 10 and 15 seconds along with earthquake magnitudes of 2.0, 2.5, 3.0 and 3.5 (Ml). The best classification of SVMR was obtained using time signals of 15 seconds and earthquake magnitudes of 3.5 with kernel exponent of 10 and complexity factor of 2, showing accuracy of 0.6 ± 16.5 kilometers, which is good enough to be used in an early warning system for the city of Bogota. It is recommended to provide this model with a previous phase of deep-shallow classification.

Published: August 2018

This paper shows the development of a decision tree for the classification of loads in a non-intrusive load monitoring (NILM) system implemented in a simple board computer (Raspberry Pi 3). The decision tree uses the total energy value of the power signal of an equipment, which is generated using a discrete wavelet transform and Parseval’s theorem. The power consumption data of different types of equipment were obtained from a public access database for NILM applications. The best split point for the design of the decision tree was determined using the weighted average Gini index. The tree was validated using loads available in the same public access database.
Production of Antimicrobial Textiles by Using Copper Oxide Nanoparticles
Authors: Hasan Redwanul
Published: August 2018

The application of nanoscale materials and structures, usually ranging from 1 to 100 nanometers (nm), is an emerging area of nanoscience and nanotechnology. Synthesis of noble metal nanoparticles for applications such as catalysis, electronics, textiles, environmental protection, and biotechnology is an area of constant interest. Recently, an awareness of general sanitation, contact disease transmission, and personal protection has led to the development of antimicrobial textiles. The development of antimicrobial cotton fabrics using Copper oxide nanoparticles has been investigated in this present work. The Copper nanoparticles were prepared by wet chemical method and were directly applied on to the 100% cotton woven fabric using pad-dry-cure method. The antibacterial activity of the finished fabrics was assessed qualitatively by agar diffusion and parallel streak method, quantitatively by percentage reduction test. The topographical analysis of the treated fabric and untreated fabric were studied and compared. The results show that the finished fabric demonstrated significant antibacterial activity against S. aureus in both qualitative and quantitative tests. The SEM analysis revealed the embedding of Copper nanoparticles in treated fabrics. The wash durability study of the treated fabric was also carried out and found to withstand up to 25 wash cycles.

The decision making process during diagnosis and treatment of a peripheral nerve injury can be complex at times. The nature and cause of nerve injury, its location, and its severity require very distinct decisions with regards to timing and intervention chosen. For good decision-making, a good knowledge of the pathophysiological conditions of peripheral nerve and its response to injury is paramount.In this article, the decision-making process related to pre-operative, intra-operative, and post-operative periods are discussed.
Acute Traumatic Cervical Facet Fractures
Authors: Gopinat Shankar
Published: August 2018

Acute cervical facet fractures are increasingly being detected due to the use of cervical spine CT imaging in the initial assessment of trauma patients. For displaced cervical facet fractures with dislocations and subluxations, early surgery can decompress the spinal cord and stabilize the spine. For patients with non-displaced cervical facet fractures, the challenge in managing these patients is the determination of spinal stability. Although many of the patients with non-displaced cervical facet fractures can be managed with a cervical collar, the imaging needs to be analyzed carefully since certain fracture patterns may be better managed with early surgical stabilization.
PEID (Percutaneous Endoscopic Interlaminar Discectomy): Cautionary Points Based on the Evidence
Authors: Lee Jun Ho
Published: August 2018

Background: Percutaneous endoscopic lumbar discectomy (PELD) is one of the most sophisticated operative procedures for the treatment of lumbar disc herniation (LDH). Endoscopic techniques are now becoming standard in many areas due to expanded technical possibilities of full-endoscopic transforaminal or interlaminar resection of herniated lumbar discs as well as stenosis. However conventional percutaneous endoscopic interlaminar discectomy (PEID) disc operations may sometimes result in subsequent untoward complications due to unnoticed iatrogenic trauma to neural structures, which is mostly related to an anatomical limitation during endoscope insertion.Methods: An appropriate operative indication of the PEID without bone removal or laminectomy can be used to treat LDH cases with an enough interlaminar space (at least ≥ 20 mm by bi-facetal distance) from the reported evidences. Otherwise, there might be several indications for requirement of bone removal; a narrow interlaminar space, disappearance of the concave shape of the upper vertebral laminae, high-grade migration of LDH, recurrent LDH, obesity, or an immobile nerve root.Conclusion: The significance of PEID lies also in its minimal damage to surrounding structures such as muscle, bone, and ligaments. A discrete radiographic evaluation from the patient preoperatively is mandatory before choosing a proper endoscopic surgical modality for the sake of optimal clinical outcome after PEID.
Durability properties of structural concretes containing secondary cementitious materials
Authors: Li Kefei , Qin Minfeng , Gui Qiang
Published: August 2018

This study investigated the durability properties of structural concretes incorporating secondary cementitious materials of fly ash and ground granulated blast-furnace slag (GGBS). The compressive strength and porosity were taken as basic properties, and the transport properties measured included electrical conductivity, chloride diffusivity, capillary absorption and gas permeability. Correlation analysis was performed on the basic and transport properties, and the pore structure of structural concretes was characterized into different patterns in terms of the connectivity and the tortuosity. The results show that (a) the concrete pores are refined by mineral admixtures and Archie’s law can describe the pore connectivity and tortuosity for saturated specimens; (b) all the transport properties correlate well with water-to-binder (w/b) ratios and the concretes with GGBS show a pronounced effect of oven-drying and self-desiccation on pore structure; and (c) chloride diffusivity and surface sorptivity correlate better with compressive strength, while chloride diffusivity, sorptivity and gas permeability should be treated as independent properties.
Race, Ethnicity, and End-of-Life Care in Dialysis Patients in the United States
Authors: Foley Robert N. , Sexton Donal J. , Drawz Paul , Ishani Areef , Reule Scott
Published: August 2018

Background

End-of-life care is a prominent consideration in patients on maintenance dialysis, especially when death appears imminent and quality of life is poor. To date, examination of race- and ethnicity-associated disparities in end-of-life care for patients with ESRD has largely been restricted to comparisons of white and black patients.

Methods

We performed a retrospective national study using United States Renal Data System files to determine whether end-of-life care in United States patients on dialysis is subject to racial or ethnic disparity. The primary outcome was a composite of discontinuation of dialysis and death in a nonhospital or hospice setting.

Results

Among 1,098,384 patients on dialysis dying between 2000 and 2014, the primary outcome was less likely in patients from any minority group compared with the non-Hispanic white population (10.9% versus 22.6%, P<0.001, respectively). We also observed similar significant disparities between any minority group and non-Hispanic whites for dialysis discontinuation (16.7% versus 31.2%), as well as hospice (10.3% versus 18.1%) and nonhospital death (34.4% versus 46.4%). After extensive covariate adjustment, the primary outcome was less likely in the combined minority group than in the non-Hispanic white population (adjusted odds ratio, 0.55; 95% confidence interval, 0.55 to 0.56; P<0.001). Individual minority groups (non-Hispanic Asian, non-Hispanic black, non-Hispanic Native American, and Hispanic) were significantly less likely than non-Hispanic whites to experience the primary outcome. This disparity was especially pronounced for non-Hispanic Native American and Hispanic subgroups.

Conclusions

There appear to be substantial race- and ethnicity-based disparities in end-of-life care practices for United States patients receiving dialysis.
Robust Reading Instruction in the Early Grades: Conceptual and Practical Issues in the Integration and Evaluation of Tier 1 and tier 2 Instructional Supports
Authors: Baker Scott K. , Fien Hank , Baker Doris Luft
Published: August 2018

Schools implement Response to Intervention (Rtl) for two major purposes. The first is to provide a coordinated system of high-quality instruction and intervention for all students in the school (Burns & Vanderheyden, 2006; Haager, Klinger, & Vaughn, 2007; National Association of State Directors of Special Education, 2006). This system can be envisioned as a framework of effective instruction to prevent academic problems from occurring and effective interventions to address problems that do occur in a timely and appropriate manner. The system is integrated and coordinated to support all students to reach primary learning objectives (Fuchs, Fuchs, & Zumeta, 2008; Greenwood, Kratochwill, & Clements, 2008). The second purpose of Rtl is to diagnose specific learning disabilities (SLD) in students who do not respond adequately to instruction and intervention (O'Conner, 2007; Reynolds & Shaywitz, 2009; Torgesen, 1997, 2004). Strong empirical evidence supports the prevention and intervention purpose of Rtl (Baker et al., 2008; Gersten et al., 2009; Greenwood, Kratochwill, & Clements, 2008; Vaughn & Fuchs, 2006), but evidence for using Rtl for SLD determination is lacking (Fuchs, Mock, Morgan, & Young, 2003; Reynolds & Shaywitz, 2009).
Effective Instructional Design and Delivery for Teaching Task-Specific Learning Strategies to Students with Learning Disabilities
Authors: Hughes Charles A.
Published: August 2018

This article proposes that how learning strategies are taught to students with learning disabilities (LD) is as important as the strategies themselves. Moreover, the preponderance of existing research supports an explicit approach for designing and delivering lessons for teaching students with LD to learn and use task-specific learning strategies. To frame this discussion, the article presents a general description of task-specific learning strategies as well as an explanation as to why many students with LD need instruction in this area. Next, it offers the design and content features of task-specific strategies found in existing strategy curricula, followed by a brief summary of the research on effective elements of instruction for teaching skills and strategies to students with LD. The remainder of.the article focuses on how to teach task-specific learning strategies in ways that incorporate identified effective and explicit teaching methodologies that address a number of learning characteristics associated with learning disabilities.
It Is More Than Just the Message: Presentation Effects in Scoring Writing
Authors: Graham Steve , Harris Karen R. , Hebert Michael
Published: August 2018

People write for many reasons. Writing is used as a tool to record ideas and information, communicate with others, chronicle experiences, express one's feelings, persuade others, facilitate learning, create imagined worlds, and evaluate students' competence (Graham, 2006). In some instances, the only intended reader of a piece of writing is the author. Examples of such writing include diaries, to do lists, and lecture notes. In other instances, writing is meant to be both read and formally evaluated by others. This kind of writing can range from term papers to state and federal writing assessments to writing requirements included as part of college entrance applications.
Masculinidades, Trabalho e Reprodução de Preconceitos: Um Estudo com Trabalhadores Gays, Lésbicas e Bissexuais

O objetivo deste artigo é analisar a masculinidade para trabalhadores não heterossexuais e como ela afeta a dinâmica social e organizacional, o que foi feito mediante um estudo qualitativo baseado em histórias orais com gays, lésbicas e bissexuais de Juiz de Fora, Minas Gerais. Os dados foram tratados pela análise de conteúdo e os resultados sugerem uma hierarquia de masculinidades cujo mais alto nível está associado à masculinidade hegemônica, heterossexual e viril. Outras masculinidades não hegemônicas podem até ser socialmente toleradas, conforme, principalmente, seu nível de discrição. Os que expõem masculinidades não hegemônicas se sujeitam a violências legitimadas pela sociedade porque ela, assim, mantém a ordem, esvaziando a identidade homossexual ao culpá-los por serem diferentes. Esse quadro sugere enxergar além dos processos formais, para que se lide com aspectos não objetivos e que afetam as pessoas, suas práticas, e seu desempenho nas organizações.

The types of social interaction in general include: cooperative (co-operation), competition (competition) and conflict (contention). In everyday social life seems besides characterized by cooperation, constantly marred by various forms of competition and conflict. Even in social life has never been found all citizens of all time cooperative. The teachings of Islam (al-Qur’an) has been tested in the history of the Prophet in unifying the Aus and Kasraj, warring for hundreds of years. Conflict and human, these two are inseparable. Therefore, conflict is a part of a necessity in life (min lawazim al-hayat) human. It is not excessive if some experts say that human history is a history of conflict. But that does not mean that the conflict left without any attempt to manage and mute. So this paper attempts to explore the spirit to manageand reduce conflicts and solutions in the perspective of the Koran.

No atendimento à Parada Cardiopulmonar (PCR), os primeiros indícios de surgimento dasmanobras de ressuscitação cardiopulmonar (RCP) originaram-se na medicina na época dosHebreus.Com o tempo, essas manobras foram aprimoradas, o que possibilitou a elaboração denormas, diretrizes e padronização no atendimento, com consequente aumento da sobrevida dosindivíduos acometidos, bem como a redução de sequelas. Objetivo: descrever a evolução dasmanobras de ressuscitação cardiopulmonar frente à parada cardiorrespiratória. Método: Tratasede uma revisão integrativa da literatura, na modalidade de pesquisa eletrônica, realizada nosmeses de março e abril de 2018, a fim de responder à seguinte questão: qual a foi a evoluçãotécnico-cientifica dos métodos de cuidado no atendimento à Parada Cardiorrespiratória? Acoleta de dados foi realizada nas bases de dados ScientificElectronic Library Online(SCIELO),Literatura Latino-americana e do Caribe em Ciências da Saúde (LILACS) e asdiretrizes da American Heart Association (AHA). Utilizou-se os descritores: cuidados deenfermagem, parada cardíaca reanimação cardiopulmonar e educação em saúde. Foramincluídos artigos publicados na íntegra entre os anos de 2011 a 2016 nos idiomas português,inglês e espanhol. Foram selecionados 04 artigos. Resultados: dos artigos selecionados, doisforam realizados por enfermeiros e dois por médicos. Contatou-se também, que três pesquisasforamlocais e um estudo multicêntrico. Identificou-se que os primeiros atendimentos estavamrelacionados a respiração boca a boca, seguido da desfibrilação ventricular; em 1960 iniciousea RCP moderna com foco na compressão sobre o terço inferior do esterno, e atualmente asdiretrizes estão baseadas no suporte básico de vida: C- compressões, A- abertura de vias aérease B- respiração, com foco nas compressões torácicas. Conclusão: uma atendimento à PCR bemexecutado e de forma precoce, garante uma evolução na recuperação do quadro da vítima.Tendo visto isso, é de extrema importância a capacitação permanente dos profissionais,baseada nos avanços técnico-científicos constantes, visando a qualidade de vida da sociedade.Além de profissionais capacitados, estimular o treinamento de suporte básico para a populaçãoleiga é essencial para uma boa evolução do quadro.

Animais peçonhentos são aqueles que, por instinto de sobrevivência e por sua proteção, estãosuscetíveis a inocular em sua vítima um elemento nocivo proveniente de glândulas exclusivas,por onde é secretado o veneno, podendo ocasionar a morte. O diagnóstico dos acidentes porestes animais depende tanto do reconhecimento do animal quanto das manifestações clínicasapresentadas pelo paciente, sendo o profissional de enfermagem de suma importância para aresolução efetiva do caso. Trata-se de revisão integrativa que percorreu as fases de delimitaçãodo tema, desenvolvimento de questão norteadora, busca e seleção dos artigos, categorização eavaliação dos dados e síntese dos dados. Após delimitar o tema, chegou-se na seguinte questãonorteadora: Em pacientes vítimas de acidentes com animais peçonhentos, quais os cuidadosefetivos da Enfermagem? A busca dos artigos foi realizada entre os dias 10 e 19 de março de2018, na biblioteca virtual SciELO (ScientificElectronic Library Online), e nas bases de dadosLILACS e BVS, além do Google Acadêmico. Os critérios de seleção dos artigos foram: ano depublicação (a partir de 2014), país (Brasil), idioma (português), tema principal do estudo e textocompleto disponível. Os artigos que se repetiram na busca foram excluídos. Foram encontrados191 artigos relacionados ao tema, e após a seleção de acordo com os critérios de inclusãochegou-se em 6 artigos, que foram utilizados neste trabalho. Os estudos encontrados para estarevisão mostram que os cuidados efetivos da Enfermagem com pacientes vítimas de acidentescom animais peçonhentos basicamente se restringem à aplicação do soro específico, além deoutras atividades e/ou orientações relacionadas à esta prática. É de extrema relevância que todaa equipe de saúde, e principalmente o enfermeiro, sejam capacitados e conscientizados acercade sua atuação perante estes casos, o que culmina em um atendimento adequado dos pacientes,reduzindo assim a chance de complicações, sequelas e mortalidade proveniente de acidentescom animais peçonhentos.

O envelhecimento da população é uma realidade constatada em várias nações não sendo surpreendente que ele venha se colocando como um desafio também no Brasil. Neste contexto, nota-se que idosos institucionalizados apresentam um perfil diferenciado, grande nível de sedentarismo, carência afetiva, perda de autonomia causada por incapacidades físicas e mentais. Estes fatores contribuem para a grande prevalência de limitações físicas e co-morbidades refletindo na independência e autonomia. Diante deste cenário objetivou-se ofertar atividades de educação em saúde; desenvolver ações lúdicas em prol da melhoria da qualidade de vida de idosos residentes em uma instituição de longa permanência. O projeto encontra-se em desenvolvimento e até o momento, foi possível desenvolver dinâmicas, oficinas de pintura, desenho, culinária, jogos como bingo e atividades que estimulassem a desenvoltura corporal com música. Estas atividades são realizadas as segundas e terças-feiras com participação média de 7 á 10 idosos. Ressalta-se o número reduzido de participantes, diante de 111 idosos institucionalizados, o que pode estar atrelado ao comodismo e a falta de interesse. Além disso, nota-se algumas dificuldades como incapacidade de raciocínio, entendimento e manipulação de dois objetos ao mesmo tempo entre os participantes. Entretanto, as ações têm permitido com que os idosos interajam com o ambiente, dentro dos limites de suas potencialidades, o que poderá contribuir para eficácia pessoal e que se sintam envolvidos, condições que têm efeitos positivos sobre sua adaptação global.

A ascaridíase, causada pelo nematelminto Ascaris lumbricoides, é uma das helmintíases mais comuns, se não a mais, no Brasil, tendo alta prevalência, afetando principalmente pessoas residentes de áreas rurais, urbanas marginalizadas e carentes, e crianças de escolas públicas. Tendo isso em vista, o trabalho de extensão visa à prevenção primária da doença em crianças do 4º e do 5º do Ensino Fundamental da Escola Estadual Professor Jair Santos, em Passos, Minas Gerais. Na primeira visita à Escola, foi ministra uma pequena palestra lúdica, inteligível à faixa etária ouvinte, por meio de slides projetados. Foram ensinados às crianças os sintomas da ascaridíase, suas formas de infecção, e principalmente, as medidas preventivas, como sempre lavar as mãos e os alimentos antes de qualquer contato oral. Como a faixa etária encontra dificuldade em manter a atenção em assuntos fora do cotidiano, esses assuntos eram tratados por meio de personagens infantis nos slides, poucos textos escritos, e muita interação lúdica entre palestrantes e crianças, sempre visando à participação ativa dessas. Na segunda visita, foi feita uma pequena gincana com os alunos. Na quadra da Escola, foram divididas igualmente duas equipes, independente de sexo e de idade, e formadas duas fileiras. Ao som do apito, o primeiro integrante de cada fileira deveria correr até um monitor, posto a 30m de distância das fileiras, e bater na mão dele; quem batesse primeiro, deveria indicar dois membros de sua equipe para ir a uma bancada. Nessa bancada, outro monitor faria uma pergunta simples sobre a ascaridíase e, se respondida corretamente pelos alunos, a equipe que respondeu receberia um ponto, caso contrário, a equipe adversária o receberia. Venceria a equipe que tivesse mais pontos. Ao final, todos os alunos, independentemente de equipe, receberam jujubas em forma de minhoca. Com essa extensão, foi notado, por meio dos comentários, e mesmo pelas ações conscientes e inconscientes das crianças durante as atividades, que os alunos apreenderam a maioria das informações básicas necessárias à prevenção da

Introdução: O período de adolescer e adolescência é permeado por profundas alterações biopsicosocioculturais, podendo expor os adolescentes a ingerência relacionada à sua saúde e qualidade de vida. Objetivo: Descrever a realização de uma oficina educativa acerca da qualidade de vida junto a adolescentes em situação de vulnerabilidade social. Metodologia: Trata-se de um estudo descritivo, caracterizado como relato de experiência, utilizando a observação e a prática durante a realização de uma oficina desenvolvida junto à 17 atores pertencentes a uma organização social de apoio a adolescentes em situação de vulnerabilidade em uma cidade do Sul de Minas Gerais. Resultados: Dentro da oficina, foi possível abordar temáticas como alimentação, atividadefísica, autoestima, projeto de vida, espiritualidade e bem-estar. A partir da realização da oficina, evidenciou-se a necessidade da ampliação e fortalecimento da atenção ao público adolescente, visto o alto grau de vulnerabilidade demonstrado e as inúmeras dúvidas que pairam acerca da sua saúde equalidade de vida. Verificou-se que a oficina com a temáticas abordada possibilitou compartilhar experiências, dúvidas e saberes, além de propiciar o diálogo e a ação-reflexão-ação dos sujeitos, objetivando estabelecer o elo entre a reflexão e a ação consciente. Denota-se ainda que o empoderamento proporcionado pela experiência caracteriza-se como uma experiência exitosa. Recomenda-se a ampliação dessas iniciativas, visto os benefícios proporcionados pela mesma, tanto para os adolescentes quanto para a equipe. Considerações finais: Considera-se, portanto, que a experiência relatada permitiu o despertar para novos conhecimentos e reflexões, fator que contribui para um processo de crescimento mútuo. Além disso, foi possível concluir que a oficina educativacom o público adolescente se configura como um importante espaço de empoderamento, cidadania, emancipação e, prioritariamente, um espaço coletivo de promoção à saúde. Sugere-se a necessidade de estudos e reflexões sobre a temática, visto seus reflexos na saúde pública e os diversos atoresenvolvidos.
