Grupo Conexões: acolhimento psicológico através de grupos virtuais durante a pandemia da Covid-19

O objetivo deste artigo é descrever a prática de acolhimento psicológico a universitários através de grupos virtuais durante a pandemia do Covid-19. A ação foi implementada por cinco psicólogos da Universidade Federal de Campina Grande (UFCG) ao longo de cinco meses e culminou com a realização de nove encontros com periodicidade quinzenal. As principais demandas que emergiram no grupo estão relacionadas às experiências socioemocionais decorrentes do isolamento social imposto pela pandemia e ao novo modelo de ensino e aprendizagem adotado pela universidade em substituição às atividades acadêmicas presenciais. A realização do grupo em meio virtual possibilitou a continuidade do cuidado em saúde mental mesmo diante da suspensão das atividades presenciais na instituição e permitiu que os participantes compreendessem e manejassem as emoções e situações-problema vivenciadas ao longo do isolamento social. Ao apresentar a experiência de grupos virtuais de acolhimento psicológico, o artigo contribui com a teoria e a prática psicológica no âmbito universitário em tempos de pandemia

Atuação de psicólogos da Universidade Federal de Campina Grande durante a pandemia do Covid-19

This work aims to report the experience of a group of psychologists who work in Student Assistance at the Federal University of Campina Grande (UFCG) in the context of social isolation due to the Covid-19 pandemic. The reported experiences were developed between March and August 2020 by UFCG psychologists in the cities of Patos, Pombal, Sousa and Sumé. The actions are divided into three lines of work: research and evaluation with the university community during the period of social isolation, offering remote psychological assistance through Digital Information and Communication Technologies (TDICs) and developing and implementing psychosocial actions. The reported experiences contribute to psychological theory and practice in the educational context, reinforcing that the school psychologist can act in crisis situations rescuing the complexity on which life and university education are built.Este trabajo tiene como objetivo relatar la experiencia de un grupo de psicólogos que laboran en Assistencia Estudiantil en la Universidad Federal de Campina Grande (UFCG) en el contexto de aislamiento social por la pandemia Covid-19.

Finding Software Vulnerabilities in Open-Source C Projects via Bounded Model Checking

Computer-based systems have solved several domain problems, including industrial, military, education, and wearable. Nevertheless, such arrangements need high-quality software to guarantee security and safety as both are mandatory for modern software products. We advocate that bounded model-checking techniques can efficiently detect vulnerabilities in general software systems. However, such an approach struggles to scale up and verify extensive code bases. Consequently, we have developed and evaluated a methodology to verify large software systems using a state-of-the-art bounded model checker. In particular, we pre-process input source-code files and guide the respective model checker to explore them systematically. Moreover, the proposed scheme includes a function-wise prioritization strategy, which readily provides results for code entities according to a scale of importance. Experimental results using a real implementation of the proposed methodology show that it can efficiently verify large software systems. Besides, it presented low peak memory allocation when executed. We have evaluated our approach by verifying twelve popular open-source C projects, where we have found real software vulnerabilities that their developers confirmed.Comment: 27 pages, submitted to STTT journa

Desempenho de indivíduos adultos saudáveis no teste de AVD-Glittre

O teste de AVD-Glittre (TGlittre), validado para avaliar a capacidade funcional de indivíduos com doença pulmonar obstrutiva crônica, possui como desfecho o menor tempo despendido para completá-lo. Até o presente momento, pouco se sabe acerca desse tempo no desempenho de indivíduos saudáveis. O objetivo do estudo foi avaliar o tempo total de realização do TGlittre em uma amostra de indivíduos adultos saudáveis, o tempo mínimo de execução do teste, assim como a reprodutibilidade do teste nessa população. Os sujeitos foram submetidos à espirometria pré e pós-broncodilatador, avaliação antropométrica, Questionário Internacional de Atividade Física e dois TGlittre. Foram avaliados 35 indivíduos (15 homens) de 29±6 anos, com capacidade vital forçada (CVF) de 96±10,6%, volume expiratório forçado no primeiro segundo (VEF1) de 97,6±9,26%, em % do previsto, e VEF1/CVF de 0,86±0,05; altura de 1,72±0,11m; peso de 72,3±12,8kg e índice de massa corpórea de 24,5±3,62kg/ m2, sendo que 74,3% e 25,7% tinham níveis baixo e moderado de atividade física, respectivamente. A média de tempo despendido no teste com melhor desempenho foi de 2,62±0,34min. Não se encontrou diferença na execução entre as faixas etárias (p>;0,05). Houve redução, em média, de 6,3±5,8% no tempo entre o TGlittre1 e TGlittre2, porém essa diferença não foi estatisticamente significante (p>;0,05).

Qualidade de vida de pacientes submetidos à cirurgia bariátrica: estudo transversal

Purpose: Analyze factors that influenced the quality of life (QoL) of patients after bariatric surgery. Methods: A cross-sectional study was carried out, involving 307 adult bariatric surgery patients between 2012 and 2014. Data was obtained from the electronic patient records and telephone interviews. To assess the QoL, the World Health Organization Quality of Life-Bref (WHOQOL-bref) was used. A simple linear regression model was constructed, adjusted by sociodemographic variables, with p<0.05. Results: The domains with the worst scores were the physical (mean=58.45; SD±10.42) and environmental (mean=65.19; SD±11.36). The best domains were the social (mean=76.51; SD±15.71) and psychological (mean=68.70; SD±15.71). In the linear regression model, it was observed that time since the surgery was inversely associated with the physical health domain. For each month post-bariatric surgery, the patient’s average score dropped by 2.66 points, adjusted by sex and age. Conclusions: Time since the surgery could be an important determinant of the physical domain score of quality of life. Identifying the quality of life after bariatric surgery and influential factors is fundamental to prepare these patients for the changes deriving from the weight loss.Objetivo: Analizar los factores que influyeron en la calidad de vida (CV) de los pacientes después de la cirugía bariátrica. Métodos: Se llevó a cabo un estudio transversal en el que participaron 307 pacientes adultos con cirugía bariátrica entre 2012 y 2014. Se han obtenido los datos de los registros electrónicos de los pacientes y de sus entrevistas telefónicas. Después se construyó un modelo de regresión lineal simple, ajustado por variables sociodemográficas, con p <0.05. Para evaluar la CV, se utilizó la Calidad de Vida Breve de la Organización Mundial de la Salud (WHOQOL-bref). Resultados: Los dominios con las peores puntuaciones fueron el físico (media = 58,45; SD ± 10,42) y ambiental (media = 65,19; SD ± 11,36). Los mejores dominios fueron el social (media = 76.51; SD ± 15.71) y psicológico (media = 68.70; SD ± 15.71). En el modelo de regresión lineal, se observó que el tiempo desde la cirugía se asoció inversamente con el dominio de la salud física. Por cada mes posterior a la cirugía bariátrica, el puntaje promedio del paciente se redujo en 2.66 puntos, ajustado por sexo y edad. Conclusión: El tiempo transcurrido desde la cirugía puede ser un determinante importante de la puntuación del dominio físico de la calidad de vida. Identificar la calidad de vida después de la cirugía bariátrica y los factores influyentes es fundamental para preparar a estos pacientes para los cambios derivados de la pérdida de peso.Objetivo: Analisar os fatores que influenciaram a qualidade de vida (QV) dos pacientes após a cirurgia bariátrica. Método: Realizado um estudo transversal envolvendo 307 pacientes adultos submetidos à cirurgia bariátrica, no período de 2012 a 2014. Os dados foram obtidos por meio de prontuário eletrônico e entrevistas telefônicas. Para avaliar a QV, foi utilizada a World Health Organization Quality of Life-bref (WHOQOL-bref). Um modelo de regressão linear simples foi construído, ajustado por variáveis sociodemográficas, com p <0,05.Resultados: Os domínios com os piores escores foram físico (média = 58,45; DP ± 10,42) e ambiental (média = 65,19; DP ± 11,36). Os melhores domínios foram o social (média = 76,51; DP ± 15,71) e o psicológico (média = 68,70; DP ± 15,71). No modelo de regressão linear, observou-se que o tempo desde a cirurgia foi inversamente associado ao domínio saúde física. Para cada mês pós-cirurgia bariátrica, a pontuação média do paciente caiu em 2,66 pontos, ajustada por sexo e idade. Conclusão: O tempo desde a cirurgia pode ser um importante determinante do escore do domínio físico de QV. Identificar a QV após a cirurgia bariátrica e fatores que a influenciam é fundamental para preparar esses pacientes para as mudanças decorrentes da perda de peso

Testicular Morphological and Ultrasonographic Characterization of Male Gray Brocket Deers (Mazama gouazoubira) in Different Reproductive Status

Background: Gray brocket deer (Mazama gouazoubira) populations have been declining due to human intervention. Yet, only a few studies have assessed ultrasonographic testicular characteristics in cervids. Considering the relevance of monitoring testicular size, blood flow, and parenchyma, the present study aims to establish baseline information on scrotal circumference, testicular volume, and spectral Doppler parameters, to describe differences among adult male gray brocket deer in different reproductive status, and to correlate ultrasound parameters with testes size measurements.Materials, Methods & Results: Six adult male gray brocket deers were used in the study. Scrotal circumference and testicular volume were measured. B mode ultrasound images of testes (longitudinal and cross-sectional views) and epididymes were subjected to computer-assisted analysis, obtaining the numerical pixel values (NPV) and pixel standard deviation (PSD). Using spectral Doppler, supratesticular artery blood flow velocities (peak systolic velocity - PSV, end diastolic velocity - EDV, time-average maximum velocity - TAMAX, resistivity - RI and pulsatility indices - PI) were obtained. Semen was analyzed through total motility, vigor, and concentration tests. Three animals were normospermic (F+ group) and three were oligo/azoospermic (F- group). Groups were compared using were compared using a one-way ANOVA or Kruskal-Wallis followed by Student-Newman-Keuls (SNK) test. Ultrasound parameters were correlated to testes size parameters using Pearson’s correlation for parametric variables and Spearman’s correlation for non-parametric variables. F+ group presented significantly higher scrotal circumference (14.57 ± 1.19 cm), testicular volume (26.18 ± 4.94 cm3), and testes cross-sectional NPV (69.88 ± 24.00) and PSD (10.78 ± 3.42) than group F- (NPV: 28.26 ± 13.75, PSD: 6.70 ± 1.84). No significant differences were observed between the groups regarding the spectral Doppler ultrasound parameters. Significant correlations were observed between scrotal circumference and longitudinal (r = 0.76) and cross-sectional testes NPV (r = 0.89), and testicular volume was correlated with longitudinal (r = 0.78) and cross-sectional testes NPV (r = 0.91) and with cross-sectional testes PSD (ρ = 0.82).Discussion: Increased testicular echogenicity (higher NPV) has been positively associated with improved testicular growth, cell population expansion, inner and outer seminiferous tubules diameter, spermatids percentages and testis weight. In addition, more heterogenous testes (higher PSD) were associated with higher sperm output. It was suggested that the animals in group F- had compromised testicular development and spermatogenesis. The correlation observed between testes NPV and scrotal circumference was proposed to be associated with seminiferous tubules impairment. The F- group showed lower testicular volume, NPVs and PSDs in cross-sectional testicular images, suggesting higher protein levels and lower lipid contents were present in their parenchyma, influencing in testicular echogenicity and echotexture. No differences in spectral Doppler parameters were observed between the two groups. Also observed in stallions. However, PSV, EDV, TAMAX could be potential infertility indicators in other mammalians. These different results may be due to different locations of the evaluated vessel, species and techniques, age, ambient temperature, pathological conditions, and anaesthesia. Thus, it is suggested that scrotal circumference, testicular volume, and testes NPV are good indicators of male reproductive health in gray brocket deer and may help with better male selection in the species

Long-term thermal sensitivity of Earth’s tropical forests

The sensitivity of tropical forest carbon to climate is a key uncertainty in predicting global climate change. Although short-term drying and warming are known to affect forests, it is unknown if such effects translate into long-term responses. Here, we analyze 590 permanent plots measured across the tropics to derive the equilibrium climate controls on forest carbon. Maximum temperature is the most important predictor of aboveground biomass (−9.1 megagrams of carbon per hectare per degree Celsius), primarily by reducing woody productivity, and has a greater impact per °C in the hottest forests (>32.2°C). Our results nevertheless reveal greater thermal resilience than observations of short-term variation imply. To realize the long-term climate adaptation potential of tropical forests requires both protecting them and stabilizing Earth’s climate

Consistent patterns of common species across tropical tree communities

Trees structure the Earth’s most biodiverse ecosystem, tropical forests. The vast number of tree species presents a formidable challenge to understanding these forests, including their response to environmental change, as very little is known about most tropical tree species. A focus on the common species may circumvent this challenge. Here we investigate abundance patterns of common tree species using inventory data on 1,003,805 trees with trunk diameters of at least 10 cm across 1,568 locations1,2,3,4,5,6 in closed-canopy, structurally intact old-growth tropical forests in Africa, Amazonia and Southeast Asia. We estimate that 2.2%, 2.2% and 2.3% of species comprise 50% of the tropical trees in these regions, respectively. Extrapolating across all closed-canopy tropical forests, we estimate that just 1,053 species comprise half of Earth’s 800 billion tropical trees with trunk diameters of at least 10 cm. Despite differing biogeographic, climatic and anthropogenic histories7, we find notably consistent patterns of common species and species abundance distributions across the continents. This suggests that fundamental mechanisms of tree community assembly may apply to all tropical forests. Resampling analyses show that the most common species are likely to belong to a manageable list of known species, enabling targeted efforts to understand their ecology. Although they do not detract from the importance of rare species, our results open new opportunities to understand the world’s most diverse forests, including modelling their response to environmental change, by focusing on the common species that constitute the majority of their trees.Publisher PDFPeer reviewe
