Tiros na escola: algumas referências para a psicologia na assistência à comunidade escolar / School shotting: some references for psychology in school comunity support / Tíros em la escuela: algunas referencias para la psicología em la asistencia à comunidad escolar

A atuação em situações de emergências e desastres apresentam-se como um dos grandes desafios na atuação dos profissionais da Psicologia, demandando intervenções singulares, desde o primeiro contato com as vítimas e o com entorno afetado pelo ocorrido, passando pelo trabalho interdisciplinar e interinstitucional junto aos órgãos públicos de segurança, justiça, assistência e saúde. O presente artigo tem como objetivo apresentar, por meio da experiência na assistência às vítimas na Escola Estadual Raul Brasil, as particularidades e adversidades enfrentadas durante o primeiro semestre de intervenções emergenciais que antecederam a contratação de psicólogos por parte do poder público municipal para continuidade das ações. Por meio de relatos de experiência em intervenções psicológicas, obtidos em diferentes instituições para a assistência às vítimas, este trabalho também visa apresentar alternativas que possam servir de referências para a intervenção do psicólogo e da psicóloga em situações de emergências e desastres, especialmente ocorridas na comunidade escolar. Observou-se que a realização do trabalho interdisciplinar e interinstitucional somado à participação da direção da escola no planejamento das ações e a realização de plantões psicológicos e rodas de conversa junto à comunidade escolar foram fundamentais para a assistência às vítimas do ocorrido.(AU)

Timely response to emergency and disaster situations is a major challenge for Psychology professionals and require particular interventions, from initial contact with the victims and the affected environment to interdisciplinary and interinstitutional collaboration with public security, justice, assistance and health agencies. Based on the experience of providing assistance to the victims of the State School Raul Brasil, this paper presents the adversities and specificities faced during the first semester of emergency interventions implemented before psychologists were hired by municipal officials for the continuity of care. By analyzing experience reports on psychological interventions obtained from different institutions for victim assistance, this paper proposes alternatives to be used as reference for psychological intervention in emergency and disaster situations, especially those experienced by the school community. Interdisciplinary and interinstitutional collaboration with the school board for planning actions and offering psychological services and conversation circles for the school community was fundamental to assist the victims.(AU)

Carboxyhemoglobinemia as a laboratory finding in an outpatient

Resumen El monóxido de carbono (CO) es un gas producido principalmente por combustión incompleta de hidrocarburos. La intoxicación por exposición ambiental puede presentarse con síntomas inespecíficos y constituye la causa más importante de aumento de carboxihemoglobina (COHb). Su nivel en sangre depende de la duración de la exposición, la ventilación minuto y las concentraciones de CO y oxígeno en el ambiente. La elevada toxicidad radica en la hipoxia tisular que se genera. Se presenta el caso de un paciente masculino, 73 años, en seguimiento en el hospital por neumonía intersticial no específica como patología de base. En un control de laboratorio se encontró 11,9% de COHb, sin exposición a tabaco. No utilizaba calefacción a gas sino un panel cerámico eléctrico, recientemente pintado con esmalte sintético. La suspensión del uso del panel normalizó la COHb. El CO, producto de descomposición térmica del esmalte sintético, explica la causa de la intoxicación.

Abstract Carbon monoxide (CO) is a gas produced mainly by incomplete combustion of hydrocarbons. Poisoning from environmental exposure can present with nonspecific symptoms and is the most important cause of increased carboxyhemoglobin (COHb). Its blood level depends on the duration of exposure, minute ventilation, and the concentrations of CO and oxygen in the environment. The high toxicity lies in the tissue hypoxia that is generated. The case of a male patient, 73 years old, under follow-up in the hospital for non-specific interstitial pneumonia as the underlying pathology was presented. In a laboratory control, COHb 11,9% was found. There was no exposure to tobacco and there was no use of gas heating but of an electric ceramic panel, recently painted with synthetic enamel type paint. The suspension of the use of the panel normalised the COHb. The CO product of thermal decomposition of synthetic enamel explains the cause of poisoning.

Tamaulipan thornscrub after fire: an analysis of the composition of species / Espinho de Tamaulipan após incêndio: uma análise da composição das espécies

Abstract Forest fires are a natural element in many terrestrial ecosystems, in Mexico one of the main causes of loss of vegetation coverage is related to them. Nevertheless, no research has been carried out in the Tamaulipan thornscrub communities regarding post-fire regenerative strategies of plant species, therefore, is important to generate knowledge about the ecological role of fire in them. The aim of this study is to characterize the arboreal and shrub vegetation of a Tamaulipan thornscrub community in the Northeast of Mexico after a fire. To determine the composition, diversity and structure of the floral community consisting of trees and shrubs, 6 square-shaped sampling sites of 1,600 m2 were established 3 years after the fire. Margalef (DMg), Shannon-Weiner (H') and Pretzsch (A) indices were calculated to determine the richness, diversity and vertical stratification of species, respectively.23 species, 21 genera and 14 families of vascular plants were registered. The most species were Fabaceae (6) and Rhamnaceae (3) and Cordia boissieri was the specie with greater ecological weight (IVI = 20.3%). The indexes of richness and true diversity (DMg = 3.16; D = 16.44) showed high values, which suggests that the post-fire area has a good regeneration and a high species diversity. With these results we can conclude that the fire is an important agent of change in successional stages of Tamaulipan thornscrub with high values of regeneration after a surface fire.

Resumo Os incêndios florestais são um elemento natural em muitos ecossistemas terrestres, no México uma das principais causas de perda de cobertura vegetal está relacionada a eles, no entanto, nenhuma pesquisa foi realizada nas comunidades de espinheiros de Tamaulipan sobre as estratégias regenerativas pós-fogo de espécies de plantas, portanto, é importante gerar conhecimento sobre o papel ecológico do fogo neles. O objetivo deste estudo é caracterizar a vegetação arbórea e arbustiva de uma comunidade de plantas espinhosas no Tamaulipas, nordeste do México após um incêndio. Para determinar a composição, diversidade e estrutura da comunidade vegetal constituída por árvores e arbustos, seis locais de amostragem em forma de quadrado de 1.600 m2 cada um, foram estabelecidos três anos após o incêndio. Índices de Margalef (DMg), Shannon-Weiner (H') e Pretzsch (A) foram calculados para determinar a riqueza, diversidade e estratificação vertical das espécies, respectivamente. Foram registradas 23 espécies, 21 gêneros e 14 famílias de plantas vasculares. As mais ricas foram Fabaceae (6) e Rhamnaceae (3), Cordia boissieri foi a espécie com maior peso ecológico (IVI = 20,3%). Os índices de riqueza e diversidade verdadeira (DMg = 3,16; D = 16,44) apresentaram valores elevados, o que sugere que a área pós-fogo apresenta boa regeneração e alta diversidade Vegetal. Com estes resultados podemos concluir que o fogo é um importante agente de mudança nos estágios sucessionais do espinho de Tamaulipan com altos valores de regeneração após um incêndio na superfície.

Firearm-Related Fractures: Epidemiology and Infection Rate / Fraturas causadas por armas de fogo: Epidemiologia e taxa de infecção

Abstract Objective To investigate the incidence of infection in patients with gunshot-related fractures, and to correlate this finding with the occurrence of surgical debridement in the emergency room. Methods A retrospective, observational, descriptive study that included all cases of fractures caused by firearms between January 2010 and December 2014; 245 fractures in 223 patients were included. Results There was surgical-site infection in 8.5% of the fractures, and the mean number of debridements required to control the infectious process was of 1.273 ± 0.608. A correlation was identified between the surgical treatment chosen and the affected body segment (p< 0.001). The surgical treatment in the emergency room had a correlation with the occurrence of infection (p< 0.001; Chi-squared test). Conclusion Patients with gunshot injuries treated non-operatively presented less severe and stable lesions; thus, the incidence of complications in this group was found to be lower. On the other hand, those patients with complex lesions underwent debridement and external fixation. Therefore, a greater number of infectious complications in patients submitted to external fixation was found, as expected.

Resumo Objetivo Investigar a incidência de infecção em pacientes com fraturas por arma de fogo, e correlacionar esse achado com a ocorrência de desbridamento cirúrgico na sala de emergência. Métodos Estudo retrospectivo, observacional e descritivo, que incluiu todos os casos de fraturas causadas por armas de fogo entre janeiro de 2010 e dezembro de 2014; foram incluídas 245 fraturas em 223 pacientes. Resultados Houve infecção do local cirúrgico em 8,5% das fraturas, e a média de desbridamentos necessários para controlar o processo infeccioso foi de 1,273 ± 0,608. Foi identificada correlação entre o tratamento cirúrgico escolhido e o segmento corporal afetado (p< 0,001). O tratamento cirúrgico na sala de emergência teve correlação com a ocorrência de infecção (p< 0,001; teste do qui-quadrado). Conclusão Pacientes com ferimentos à bala tratados de forma não operatória apresentaram lesões menos graves e estáveis; portanto, a incidência de complicações nesse grupo foi menor. Por outro lado, os pacientes com lesões complexas foram aqueles submetidos a desbridamento e fixação externa. Portanto, como esperado, foi encontrado um maior número de complicações infecciosas em pacientes submetidos à fixação externa.

Fogo em campo cirúrgico - Medidas preventivas para cirurgia palpebral segura / Operating room fire prevention - preventive measures for safe eyelid surgery

Resumo Fogo em campo cirúrgico durante cirurgia palpebral é uma complicação intra-operatória que é dramática tanto para o paciente quanto para a equipe médica. Relatamos um caso de acidente cirúrgico durante cirurgia palpebral onde o paciente sofreu queimadura de supercílio. Houve interação entre o oxigênio usado para sedação (máscara aberta) e uma fonte de ignição representada pelo cautério monopolar. Embora o paciente tenha apresentado boa evolução clínica com recuperação total da lesão cutânea, este caso é um alerta para se evitar tais tipo de ocorrência. Ressaltamos neste trabalho quais as condições implicadas e o modo de prevenção.

Abstract Fire in the surgical field during eyelid surgery is an intra-operative complication that is dramatic for both the patient and the medical staff. It's being reported a case of surgical accident during eyelid surgery where the patient suffered a brow burn. There was interaction between the oxygen used for sedation (open mask) and a source of ignition represented by monopolar cautery. Although the patient presented good clinical evolution with complete recovery of the cutaneous lesion, this case is an alert to avoid such type of occurrence. This work highlights the conditions involved and the way of prevention.

Contra-Lateral Unintended Upper Arm Movement during Unimanual Tasks in Children with Cerebral Palsy

PURPOSE: To characterize associated reactions (ARs) in the contralateral arm across multiple muscles during unimanual tasks and to identify factors related to ARs in children with cerebral palsy (CP).MATERIALS AND METHODS: This was a prospective, cross-sectional study of 35 children with CP. The extent of ARs of the contra-lateral, non-task hand was assessed while performing three unimanual tasks (opening and clenching the fist, a finger opposition task, and tapping fingers). The occurrence of ARs in each trial was evaluated separately for each task using a four-point scale (total scores ranged from 0 to 12). Surface electromyography (SEMG) was used to measure the firing activity of the muscles of the opposite arm during the task. The Manual Ability Classification System and Melbourne Assessment 2 (MA-2) were used to evaluate upper limb function.RESULTS: AR scores were higher in the more-affected limb than in the less-affected limb. SEMG data on the non-task hand showed motor overflow up to the elbow muscles in the more-affected limb. Root mean square ratios of EMG signals were significantly higher in children with ARs than in children without ARs. Multiple regression analysis showed both age and MA-2 to be significant factors related to ARs in the more-affected limb.CONCLUSION: Children with visible ARs showed motor overflow in the non-task limb during unimanual hand tasks. Age and upper limb function were significantly related to the extent of ARs in the more-affected limb of children with CP.

The effects of repetitive firing processes on the optical, thermal, and phase formation changes of zirconia

PURPOSE: The aim of this study was to investigate the effect of different numbers of heat treatments applied to superstructure porcelain on optical, thermal, and phase formation properties of zirconia.MATERIALS AND METHODS: Forty zirconia specimens were prepared in the form of rectangular prism. Specimens were divided into four groups (n = 10) according to the number of firing at heating values of porcelain. Color differences and translucency parameter were measured, and X-ray diffraction (XRD) analysis and differential scanning calorimetry (DSC) were performed. Data were analyzed with analysis of variance (ANOVA).RESULTS: There were no statistically significant differences in ΔE, TP, L, a, and b value changes of the zirconia specimens as a result of repetitive firing processes (P>.05).CONCLUSION: Although additional firing processes up to 4 increase peak density in thermal analysis, additional firing processes up to 4 times can be applied safely as they do not result in a change in color and phase character of zircon frameworks.

Impacto da queima da cana-de-açúcar sobre internações hospitalares por doenças respiratórias / The impact of sugarcane burning on hospitalization due to respiratory diseases

Resumo O objetivo deste artigo é avaliar o impacto das emissões da queima da cana-de-açúcar sobre o número de internações hospitalares por doenças respiratórias em uma região canavieira. Registros de internações hospitalares por doenças respiratórias foram adquiridas a partir da base de dados referentes ao sistema de informações hospitalares do sistema único de saúde (SIH-SUS), no período de 28 de março de 2011 a 28 de dezembro de 2012. Níveis de MP10, NO2, O3, temperatura e umidade relativa foram registradas. Modelos de regressão logística foram construídos para analisar a associação entre o número total de internações, poluentes atmosféricos e variáveis meteorológicas. Foram registradas 1.179 internações, dentre elas a pneumonia mostrou aumento significativo no período de queima (p = 0,005). Neste mesmo período observou-se que o cluster MP10 e NO2 influenciou 67,9% (IC95%: 11,111-2,537), seguido do cluster MP10, NO2, O3 e temperatura que influenciou 91,1% (IC95%: 1,116; 3,271) no número total de internações. Durante o período de queima houve maior número de internações por doenças respiratórias, principalmente de pneumonia, quando foi observada a influência dos poluentes e temperatura no processo de adoecimento da população.

Abstract The scope of this article is to evaluate the impact of emissions from sugarcane burning on hospital admission numbers for respiratory diseases in a sugarcane region. Hospital admission records for respiratory diseases were acquired from the database of the Hospital Information System of the Unified Health System (SIH-SUS) in the period from March 28, 2011 to December 28, 2012. Levels of PM10, NO2, O3, Temperature and Relative Humidity were recorded. Logistic regression models were created to analyze the association between the total number of hospitalizations, atmospheric pollutants and meteorological variables. A total of 1,179 hospitalization admissions were recorded, with a significant increase in cases of pneumonia in the burning period (p = 0.005). Likewise, it was observed that the cluster of PM10 and NO2 was influenced 67.9% (95% CI: 11.111-2.537) followed by cluster PM10, NO2, O3 and Temperature that influenced 91.1% (95% CI: 1.116; 3.271) in the total number of hospitalization admissions. During the sugarcane burning period there were more hospitalization admissions due to respiratory tract diseases, mainly pneumonia, where the influence of air pollutants and temperature in the process of illness in the population was detected.

"Among dead and wounded": mapping, characterization and analysis of fires with victims in Recife's metropolitan zone / "Entre mortos e feridos": mapeamento, caracterização e análise dos incêndios com vítimas na região metropolitana do Recife / "Entre muertos y heridos": cartografía, caracterización y análisis de los incendios con víctimas en la zona metropolitana de Recife

This article presents the mapping and analysis of fires with dead and wounded people in the Metropolitan Region of Recife (MRR) served by the Firefighters Department from 2013 to 2016. There was an average rate of 1 death per million inhabitants, similar to countries such as Singapore and Vietnam. The weighted number of fires per wounded or dead person results in rates of 0.5 and 1.7 per 100 recorded fires, respectively. These numbers are concerning, especially when compared to rates from other regions in the world. The victims of fires in MRR were shown to generally not be a perceivable problem in terms of common sense, yet they are real and require accurate analysis and effective measures.

Este artigo apresenta o mapeamento e a análise de incêndios com mortes e feridos na Região Metropolitana do Recife ­ RMR, atendidos pelo Corpo de Bombeiros, no período de 2013 a 2016. Verificou-se uma taxa média de 1 morte por milhão de habitantes, semelhante a países como Singapura e Vietnam. Quando se pondera a quantidade de incêndios para que haja um ferido ou morto, as taxas se apresentam respectivamente em 0,5 e 1,7 por 100 incêndios registrados ­ sendo estes números preocupantes, principalmente quando comparados com taxas de outras regiões no mundo. Conclui-se que as vítimas de incêndios na Região (RMR) são um problema silente ao senso comum, mas real e que exige análise acurada e providências efetivas.

Este artículo presenta la cartografía y análisis de incendios con muertes y heridos en la Zona Metropolitana de Recife (ZMR), atendidos por el Cuerpo de Bomberos, en el período de 2013 a 2016. Se ha verificado un promedio de 1 muerte por millón de habitantes, semejante a países como Singapur y Vietnam. Cuando se examina la cantidad de incendios para que haya un herido o muerto, los promedios se presentan respectivamente de 0,5 y 1,7 por 100 incendios registrados, lo cual es preocupante, principalmente en comparación con los promedios de otras regiones del mundo. Se concluye que las víctimas de incendios en la ZMR son un problema silencioso y real, lo que exige un análisis cuidadoso y diligencias efectivas.

Social Disaster Adaptation Experiences of Railroad Workers: Focused on the Iri Station Explosion of 1977 / 산업간호학회지

PURPOSE: The Iri station explosion that occurred in 1977 was a major social disaster in Korea, caused by a fire in a train equipped with explosives. The purpose of this study was to investigate the social disaster adaptation experiences of railroad workers. METHODS: This study was based on qualitative research using phenomenological methodology. Participants were six railroad workers who experienced the Iri station explosion. Data were collected through in-depth interviews with individual workers from March to June, 2018. The data analysis method was based on Colaizzi's approach. RESULTS: Experiences of railroad workers were categorized into 12 themes and the following 6 theme clusters: (1) Anxiety due to the extreme vibration and crash, (2) Terror regarding the horrible situation that one cannot face, (3) Anger about the cause of the explosion and a sense of relief about survival, (4) Confusion regarding different rumors, (5) Various efforts to return to daily life, and (6) Trauma that continues to exist. CONCLUSION: The findings of this study recommend that railroad organizations and managers should pay attention to enhance disaster preparedness and develop organizational disaster coping guidelines for members. The results of this study can help us to better understand the various aspects of the Iri station explosion of 1977.

Factors associated with the Health-related Quality of Life of Firefighters / 정신간호학회지

PURPOSE: The purpose of this study was to identify the relationships among occupational identity, social support, posttraumatic growth, and health-related quality of life regarding firefighters.METHODS: The study was conducted with 149 firefighters working at two fire stations in South Gyeongsang Province. Data were collected between August and September 2018. There were four research instruments in the structured survey, including the occupational identity scale, social support scale, Korea Posttraumatic Growth Inventory and World Health Organization Quality of Life Assessment Instrument.RESULTS: As a result, the quality of life of firefighters was positively correlated with social support, occupational identity, and posttraumatic growth. The factors associated with the quality of life of firefighters were social support (β=.36, p < .001), and occupational identity (β=.31, p < .001).

New prehospital scoring system for traumatic brain injury to predict mortality and severe disability using motor Glasgow Coma Scale, hypotension, and hypoxia: a nationwide observational study

OBJECTIVE: Assessing the severity of injury and predicting outcomes are essential in traumatic brain injury (TBI). However, the respiratory rate and Glasgow Coma Scale (GCS) of the Revised Trauma Score (RTS) are difficult to use in the prehospital setting. This investigation aimed to develop a new prehospital trauma score for TBI (NTS-TBI) to predict mortality and disability.METHODS: We used a nationwide trauma database on severe trauma cases transported by fire departments across Korea in 2013 and 2015. NTS-TBI model 1 used systolic blood pressure < 90 mmHg, peripheral capillary oxygen saturation < 90% measured via pulse oximeter, and motor component of GCS. Model 2 comprised variables of model 1 and age >65 years. We assessed discriminative power via area under the curve (AUC) value for in-hospital mortality and disability defined according to the Glasgow Outcome Scale with scores of 2 or 3. We then compared AUC values of NTS-TBI with those of RTS.RESULTS: In total, 3,642 patients were enrolled. AUC values of NTS-TBI models 1 and 2 for mortality were 0.833 (95% confidence interval [CI], 0.815 to 0.852) and 0.852 (95% CI, 0.835 to 0.869), respectively, while AUC values for disability were 0.772 (95% CI, 0.749 to 0.796) and 0.784 (95% CI, 0.761 to 0.807), respectively. AUC values of NTS-TBI model 2 for mortality and disability were higher than those of RTS (0.819 and 0.761, respectively) (P < 0.01).CONCLUSION: Our NTS-TBI model using systolic blood pressure, motor component of GCS, oxygen saturation, and age was feasible for prehospital care and showed outstanding discriminative power for mortality.

Operation Room Fire: Caution for Using Electrocautery after Rinsing Operation Field at the End of the Surgery with Alcohol-Based Cleansing Solutions

A Computational Modeling Reveals That Strength of Inhibitory Input, E/I Balance, and Distance of Excitatory Input Modulate Thalamocortical Bursting Properties

The thalamus is a brain structure known to modulate sensory information before relaying to the cortex. The unique ability of a thalamocortical (TC) neuron to switch between the high frequency burst firing and single spike tonic firing has been implicated to have a key role in sensory modulation including pain. Of the two firing modes, burst firing, especially maintaining certain burst firing properties, was suggested to be critical in controlling nociceptive behaviors. Therefore, understanding the factors that influence burst firing properties would offer important insight into understanding sensory modulation. Using computational modeling, we investigated how the balance of excitatory and inhibitory inputs into a TC neuron influence TC bursting properties. We found that intensity of inhibitory inputs and the timing of excitatory input delivery control the dynamics of bursting properties. Then, to reflect a more realistic model, excitatory inputs delivered at different dendritic locations—proximal, intermediate, or distal—of a TC neuron were also investigated. Interestingly, excitatory input delivered into a distal dendrite, despite the furthest distance, had the strongest influence in shaping burst firing properties, suggesting that not all inputs equally contribute to modulating TC bursting properties. Overall, the results provide computational insights in understanding the detailed mechanism of the factors influencing temporal pattern of thalamic bursts.
