A resistência do fluxo inspiratório modifica a intensidade de uma sessão de pilates? / Does inspiratory flow resistance modify the intensity of a pilates session?

INTRODUÇÃO: As evidências sobre a melhora da capacidade funcional utilizando o Método Pilates não são contundentes. Uma possibilidade de melhorar o efeito de uma sessão de Pilates sobre a capacidade cardiorrespiratória de seus praticantes é utilizar a resistência de fluxo inspiratório (RFI) de forma concomitante. Esse efeito pode ser visualizado através da determinação do limiar glicêmico (LG), técnica utilizada como marcador de intensidade do exercício. OBJETIVO: Testar a hipótese de que a utilização de RFI em uma sessão de pilates antecipa o LG. MÉTODOS: Estudo crossover de corte transversal. Foram avaliados 26 indivíduos de ambos os sexos, sendo 10 do sexo masculino, sadios e com idade entre 20 e 40 anos. Os voluntários foram randomizados para dois protocolos: Protocolo RFI ­ 11 movimentos do Método Pilates com RFI utilizando 20% da pressão inspiratória máxima; e Protocolo sem RFI (SRFI) ­ 11 movimentos do Método Pilates sem RFI. Os dois protocolos foram realizados no mesmo dia, sendo um pela manhã e outro à tarde, conforme randomização feita por sorteio aleatório simples. No repouso e ao final de cada movimento coletas de sangue capilar foram realizadas para dosagem da glicemia e construção da curva glicêmica. O LG foi determinado no menor ponto da curva. RESULTADOS: O LG foi antecipado no protocolo que utilizou RFI, ou seja, no protocolo com RFI o LG foi visualizado no sexto exercício, enquanto no protocolo SRFI o LG foi visualizado no nono exercício (p<0,05). CONCLUSÃO: A RFI antecipou o LG, o que sugere que a RFI aumenta a intensidade de uma sessão de pilates. Isso aventa a hipótese de que a RFI pode proporcionar a médio e longo prazo benefícios adicionais aos praticantes do Método Pilates.

INTRODUCTION: The evidence on the improvement of functional capacity using the Pilates Method is not conclusive. One possibility to improve the effect of a Pilates session on the cardiorespiratory capacity of its practitioners is to use the inspiratory flow resistance (IFR) concomitantly. This effect can be visualized by determining the glycemic threshold (GT), a technique used as an exercise intensity marker. OBJECTIVE: To test the hypothesis that the use of IFR in a Pilates session anticipates GT. METHODS: Cross-sectional crossover study. A total of 26 individuals of both genders were evaluated, 10 of whom were male, healthy, and aged between 20 and 40 years. The volunteers were randomized to two protocols: Protocol IFR - Eleven movements of the Pilates method with IFR using 20% of the maximum inspiratory pressure, and Protocol no IFR (NIFR) - Eleven movements of the Pilates method without IFR. The two protocols were performed on the same day, one in the morning and the other in the afternoon, according to randomization by simple random draw. At rest and at the end of each movement, capillary blood collections were performed to measure blood glucose and construct the glycemic curve. GT was determined at the smallest point on the curve. RESULTS: The GT was anticipated in the protocol that used IFR; that is, in the protocol with IFR, the GT was visualized in the sixth exercise, while in the NIFR protocol, the GT was visualized in the ninth exercise (p<0.05). CONCLUSION: IFR anticipated GT, which suggests that IFR increases the intensity of a Pilates session. This suggests the hypothesis that IFR can provide additional medium and long-term benefits to Pilates method practitioners.

Psychometric properties of the online Satisfaction with Life Scale in university students from a low-income region

Purpose: To test the feasibility, reliability, and validity of the Satisfaction with Life Scale (SWLS) in an online format in university students from a low-income region. Methods: This was a psychometric study, involving a study of reliability (n = 117) and validity (n = 195) in university students from a region with a Gini index of 0.56. The scale was applied at two time points with an interval of 2 weeks. This scale measures satisfaction with life based on five statements and responses ranging from 1 to 7 (strongly disagree to strongly agree). We conducted the reliability assessment using temporal stability and internal consistency and construct validity assessment by internal structure solution. Results: All SWLS items showed acceptable (rho > 0.30) and significant (p < 0.05) temporal stability and acceptable internal consistency (alpha > 0.70). In construct validity (internal structure), we identified a factor with an explained variance of 59.0% in the exploratory factor analysis. Additionally, in the confirmatory factor analysis, we identified a one-factor structure solution for SWLS with an acceptable model fitting (chi-square/degrees of freedom [X2/df] = 6.53; Tucker-Lewis Index [TLI] = 0.991; Comparative Fit Index [CFI] = 0.996; root mean square error of approximation [RMSEA] = 0.040; standardized root mean-squared residual [SRMR] = 0.026). Conclusion: The Satisfaction with Life Scale, in the online format, is a reliable and valid tool for university students in a low-income context.

Comparison of fish assemblages recorded by visual census and video census / Comparación de ensamblajes de peces registrados por censo visual y censo por video

Abstract Introduction: Underwater visual censuses are the basis of many studies on fish ecology, however, a series of limitations and errors influence the traditional visual estimation of fish richness and abundance. Video techniques have been proposed to mitigate such errors, but there are few studies that compare the effectiveness of both methods. Objective: To compare the estimates obtained through the traditional census and the video census of the fish community of two localities in the central Mexican Pacific. Methods: We studied the fish community of two bays of Huatulco, Oaxaca, Mexico. We established sampling points in each bay and applied a traditional census and a diver-operated video census. We used comparison tests and analysis of similarity tests to compare richness, abundance and diversity by locality; and permutation tests for the same parameters at each sampling point. Results: Both censuses provide similar estimates regarding the richness, abundance, and diversity by locality and by sampling points. There were no statistically significant differences between traditional census and a diver-operated video census in terms of richness, abundance, and diversity. Conclusions: Video census using the diver-operated video technique can be used as a complement or as an alternative to traditional census. Its use can provide a more complete assessment, increase data acquisition, and implement long-term monitoring programs in areas where there are economic limitations for its operation.

Resumen Introducción: Los censos visuales submarinos son la base de muchos estudios sobre ecología de peces, sin embargo, una serie de limitaciones y errores influyen en la estimación visual tradicional de la riqueza y abundancia de peces. Se han propuesto las técnicas de video para mitigar tales errores, pero existen pocos estudios que comparen la efectividad de ambos métodos. Objetivo: Comparar las estimaciones obtenidas mediante el censo tradicional y el video censo de la comunidad de peces de dos localidades del Pacífico central mexicano. Métodos: Se estudió la comunidad de peces de dos bahías de Huatulco, Oaxaca, México. Se establecieron puntos de muestreo en cada bahía y se aplicó el censo tradicional y video censo operado por buzo. Se emplearon pruebas de comparación y análisis de pruebas de similitud para comparar riqueza, abundancia y diversidad por localidad; y pruebas de permutación para los mismos parámetros en cada punto de muestreo. Resultados: Ambos censos proporcionan estimaciones similares en cuanto a la riqueza, abundancia y diversidad por localidad y por punto de muestreo. No existieron diferencias estadísticamente significativas entre el censo tradicional y video censo operado por buzo respecto a riqueza, abundancia y diversidad. Conclusiones: El video censo mediante la técnica de video operado por buzo puede utilizarse como complemento o como alternativa al censo tradicional. Su uso puede proporcionar una evaluación más completa, aumentar la adquisición de datos e implementar programas de monitoreo a largo plazo en áreas donde existen limitaciones económicas para su operación.

Anidación del chorlo nevado (Charadrius nivosus) en Atotonilco, Jalisco, México

El chorlo nevado (Charadrius nivosus) es una de las aves playeras menos abundantes. Es una especie amenazada cuyas poblaciones se encuentran en constante declive. México es importante para las poblaciones de esta especie, pero existe poca información sobre su reproducción y amenazas. Con el objetivo obtener datos sobre su anidación y potenciales amenazas existentes, realizamos un monitoreo de la población del chorlo nevado en la laguna de Atotonilco durante la temporada reproductiva (marzo-julio) del año 2020. Efectuamos conteos de individuos y nidos, tamaño de nidada, fecha aproximada de puesta de los huevos y observaciones sobre las amenazas presentes durante este periodo. Los machos representaron el 85% (n = 140) de la población total y el mes con la mayor cantidad de nidos fue mayo (n = 15). El tamaño promedio de la nidada fue de 2.5 huevos. La superficie de agua fue variable durante los meses de muestreo, pero no se comprobó estadísticamente que a mayor desecación el tamaño de la nidada disminuyera (p = 0.09). Las principales amenazas identificadas fueron los vehículos motorizados y la ganadería. La laguna de Atotonilco es un sitio clave para la reproducción del chorlo nevado y se deben implementar acciones de manejo que permitan ampliar la presencia de agua y regulen las actividades humanas.

The snowy plover (Charadrius nivosus) is one of the least abundant shorebirds. It is an endangered species whose populations are in steady decline. Mexico is important for the populations of this species, but there is little information on its reproduction and threats. To obtain data on nesting and potential threats, we monitored the snowy plover population at Atotonilco Lagoon during the breeding season (March-July) in 2020. We conducted counts of individuals and nests, clutch size, approximate egg-laying date, and observations on threats present during this period. Males represented 85% (n = 140) of the total population and the month with the highest number of nests was May (n = 15). The average nest size was 2.5 eggs. Water surface area was variable during the sampling months, but it was not statistically proven that the greater the desiccation, the smaller the nest size (p = 0.09). The main threats identified were motorized vehicles and livestock. The Atotonilco Lagoon is a key site for snowy plover reproduction and management actions should be implemented to increase the presence of water and regulate human activities.

COVID-19 in the perioperative period of cardiovascular surgery: the brazilian experience

Abstract Introduction: We investigated the clinical course and outcomes of patients submitted to cardiovascular surgery in Brazil and who had developed symptoms/signs of coronavirus disease 2019 (COVID-19) in the perioperative period. Methods: A retrospective multicenter study including 104 patients who were allocated in three groups according to time of positive real time reverse transcriptase-polymerase chain reaction (RT-PCR) for the SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2): group 1, patients who underwent cardiac surgery > 10 days after positive RT-PCR; group 2, patients with a positive RT-PCR within 10 days before or after surgery; group 3, patients who presented positive RT-PCR > 10 days after surgery. The primary outcome was mortality and secondary outcomes were postoperative complications, intensive care unit (ICU) length of stay, and postoperative days of hospitalization. Results: The three groups were similar with respect to age, the European System of Cardiac Operative Risk Evaluation score, and comorbidities, except hypertension. Postoperative complications and death were significantly higher in groups 2 and 3 than in group 1, and no significant difference between groups 2 and 3 was seen. Group 2 showed a high prevalence of surgery performed as an urgent procedure. Although no significant differences were observed in ICU length of stay, total postoperative hospitalization time was significantly higher in group 3 than in groups 1 and 2. Conclusion: COVID-19 affecting the postoperative period of patients who underwent cardiovascular surgery is associated with a higher rate of morbidity and mortality. Delaying procedures in RT-PCR-positive patients may help reduce risks of perioperative complications and death.

ABSTRACT Introduction: obstructive Sleep Apnea Syndrome (OSAS) is a serious confition that compromises the quality of life and survival of patients. Its main risk fator in adults is obesity and the gold standard test for diagnosis is polysomnography (PSG), mainly through the apneia-hypopnea index (AHI). Objective: to analyze the sleep pattern of obese patients with indication for bariatric surgery, determining the main polisomnographic parameters compromised by obesity. Methods: This work is a cross-sectional study with analysis of polysomnography perfomed in patients with obesity in the peroperative period of bariatric surgery at a clinic in Vitória da Conquista/BA during 2017. The Epi Info 7 platform was used for analysis of the data. Results: 58 polysomnographic reports were analyzed, with 56,9% morbdly obese and 43,1% non-morbid. The prevalence of OSAS was 70,68% and de AHI ranged from zero to 84,6 with a mean of 19,47±22,89 e/h. morbidly obese, compared to "non-morbid", had a longer saturation time below 80% and 90% (0,4±0,93 vs. 0,12±0,45 e 4,87±7,38 vs. 1,36±2,87 respectively; p-value=0,02 in both), worse index respiratory disorders ((29,24±25,36 vs. 16,88±16,21; p-value=0,02), higher AHI (24,71±25,68 vs. 12,56±16,67; p-value=0,02), higher hypopnea index values (16,41±17,10 vs. 6,99±8,52; p-value=0,006) and lower minimum saturation (78,24±9,80 vs. 85,24±6,33; p-value=0,004). Conclusions: the high prevalence of OSAS found confirms its indication in the preoperative period of bariatric surgery. The main respiratory event involved in most individuals with OSAS was the hypopnea index.

RESUMO Introdução: a Síndrome da Apnéia e Hipopnéia Obstrutiva do Sono (SAHOS) é uma grave patologia que compromete a qualidade de vida e sobrevida dos portadores. Seu principal fator de risco em adultos é a obesidade e o exame padrão ouro para diagnóstico é a polissonografia (PSG), sobretudo através do índice de apneiahipopneia (IAH). Objetivo: analisar o padrão de sono dos pacientes obesos com indicação à cirurgia bariátrica, determinando os principais parâmetros polissonográficos comprometidos pela obesidade. Métodos: Este trabalho se trata de um estudo transversal com análise das polissonografias feitas em pacientes com obesidade no préoperatório de cirurgia bariátrica em uma clínica em Vitória da Conquista/BA durante o ano de 2017. Foi utilizada a plataforma Epi Info 7 para análise dos dados. Resultados: analisados 58 laudos polissonográficos, sendo 56,9% obesos mórbidos e 43,1% não mórbidos. A prevalência de SAHOS foi 70,68% e o IAH variou de zero a 84,6 com média de 19,47±22,89 e/h. Os obesos mórbidos, comparados aos "não mórbidos", tiveram maior tempo de saturação abaixo de 80% e 90% (0,4±0,93 vs. 0,12±0,45 e 4,87±7,38 vs. 1,36±2,87 respectivamente; p=0,02 em ambos), pior índice de distúrbios respiratórios (29,24±25,36 vs. 16,88±16,21; p=0,02), maior IAH (24,71±25,68 vs. 12,56±16,67; p=0,02), valores de índices de hipopneia superiores (16,41±17,10 vs. 6,99±8,52; p=0,006) e menor saturação mínima (78,24±9,80 vs. 85,24±6,33; p=0,004). Conclusões: a alta prevalência de SAHOS encontrada ratifica sua indicação no pré-operatório de cirurgia bariátrica. O principal evento respiratório envolvido na maioria dos indivíduos com SAHOS foi o índice de hipopneia.

General principles and overview of vascular contrast-enhanced ultrasonography

Ultrasonography (US) is the first-line modality for the evaluation of vascular pathology. Although well-established for many diseases, US has inherent limitations that can occasionally hinder an accurate diagnosis. The value of US was improved by the introduction of microbubbles as ultrasonographic contrast agents (UCAs) and the emergence of contrast-enhanced ultrasonography (CEUS), following the introduction of second-generation UCAs and the emergence of modern contrast-specific techniques. CEUS offers valuable information about vascular disease, both on a macrovascular and a microvascular level, with well-established applications for carotid disease, post-interventional follow-up of abdominal aortic aneurysms, and the assessment of portal vein thrombosis. The purpose of this review is to discuss the principles of CEUS and to present an overview of its vascular applications.

Utilizando un recurso inusual: escarabajos del estiércol atraídos a milpiés (Diplopoda: Spirobolida) / Using an unusual resource: dung beetles attracted to millipedes (Diplopoda: Spirobolida)

Entre 2017 y 2018 se realizaron muestreos durante cuatro meses en un fragmento de bosque tropical perennifolio de un área natural protegida de Chiapas, México. Se instalaron trampas de caída ubicados a lo largo de un trayecto de aproximadamente 500 m. Las trampas fueron cebadas con individuos recién muertos de Messicobolus magnificus, un milpiés abundante en la reserva durante la temporada lluviosa. Se capturaron 108 individuos de cuatro especies de escarabajos: Canthon vazquezae (92), Deltochilum pseudoparile (13), Coprophanaeus corythus (2) y Ateuchus rodriguezi (1). Únicamente D. pseudoparile ha sido previamente recolectada con carroña de otras especies de milpiés. El uso de este tipo de recurso posiblemente sea una fuente alterna que permite reducir la competencia interespecífica por otros recursos efímeros entre los Scarabaeinae.

Between 2017 and 2018, samplings out for four months in a tropical evergreen forest fragment from a natural protected area of Chiapas, Mexico, were carried. Pitfall traps were installed along a path of about 500 m. The traps were baited with freshly killed individuals of Messicobolus magnificus, an abundant millipede during the rainy season in the reserve. 108 individuals of four beetles' species were captured: Canthon vazquezae (92), Deltochilum pseudoparile (13), Coprophanaeus corythus (2) and Ateuchus rodriguezi (1). Only D. pseudoparile has been previously collected with carcasses from other millipede species. The use of this resource type is possibly an alternative source that reduces interspecific competition among the Scarabaeinae for other ephemeral resources.

Este trabalho apresenta uma síntese de discussões realizadas em um grupo de estudos sobre relações étnico-raciais, composto por psicólogas brancas pós-graduandas, pelo período de três semestres. Os estudos foram motivados pela lacuna na formação em Psicologia no que diz respeito às relações étnico-raciais. São discutidos os efeitos da branquitude na formação subjetiva e profissional, a partir de três eixos: 1. Uma breve leitura histórica sobre a construção social da ideia de raças humanas e sua influência no pensamento psicológico brasileiro. 2. Histórico sobre como a Psicologia se dedicou ao estudo das relações étnico-raciais no Brasil.E 3. contribuições da Psicologia Crítica no estudo da branquitude. Esperamos que estas reflexões favoreçam a Construção de diálogos com profissionais, docentes e pesquisadores de Psicologia sobre a necessidade de formação a respeito das relações étnico-raciais e, principalmente, a necessidade de se desenvolver uma branquitude crítica para uma postura ética na atuação profissional.

Esperamos que estas reflexiones favorezcan la construcción de diálogos con profesionales, docentes e investigadores de Psicología sobre la necesidad de formación acerca de las relaciones étnico-raciales y, principalmente, la necesidad de desarrollar una branquitud crítica para una postura ética en la actuación profesional.

This work aims to share reflections carried out in a group of studies on ethnic-racial relations, carried out by white postgraduate psychologists for a period of three semesters. The studies were motivated by the gap we identified in Psychology training regarding ethnic and racial relations. The effects of whiteness on subjective and professional formation are discussed, from three parts: 1. A brief historical reading about the social construction of the idea of ​​human races and its influence on Brazilian psychological thinking. 2. History about how Psychology was dedicated to the study of ethnic-racial relations in Brazil.A 3. Contributions of Critical Psychology in the study of whiteness. We hope that these reflections favor the construction of dialogues with professionals, teachers and researchers of Psychology on the need for training on ethnic-racial relations and, especially, the need to develop a critical whiteness to an ethical stance in professional practice.

Escarabajos coprófagos (Coleoptera: Scarabaeidae: Scarabaeinae) en la reserva El Zapotal, Chiapas, México

El Centro Ecológico y Recreativo El Zapotal (CEREZ) se caracteriza por presentar uno de los últimos remanentes de selva mediana en la región central de Chiapas, México. Sin embargo, el conocimiento de algunos grupos taxonómicos de la reserva no es del todo adecuado. En este trabajo se analiza la composición y estructura, así como la distribución temporal de los escarabajos coprófagos que habitan en el CEREZ. Se realizaron muestreos mensuales entre febrero de 2013 y enero de 2014 utilizando trampas de caída cebadas con estiércol de seis especies de mamíferos que se mantienen en cautiverio al interior del Zoológico Miguel Álvarez del Toro (ZooMAT). Se presenta una lista anotada de 22 especies agrupadas en 12 géneros y seis tribus de Scarabaeinae. Onthophagus anthracinus, Canthon femoralis, Onthophagus landolti y Copris laeviceps aportan el 89.7% de la abundancia total. La curva de rarefacción muestra una tendencia asintótica, con un 92% de completitud. La fauna capturada muestra una marcada distribución temporal (p < 0.01), observando los valores más altos de riqueza y abundancia durante los meses de la temporada lluviosa. Los registros representan el 7.53% de la diversidad conocida en México y el 18.2% de las especies reportadas en el estado de Chiapas. A pesar de representar un pequeño remanente de selva tropical y de la constante presión antrópica generada por la zona urbana, El Zapotal conserva una fauna de escarabajos coprófagos representativa a nivel regional, resaltando la importancia de la reserva como refugio de especies.

El Zapotal Recreational Ecological Preserve (CEREZ) is characterized by presenting one of the last remnants of tropical forest in the central region of Chiapas, Mexico. However, the knowledge of some taxa of the reserve is not entirely adequate. In this work the composition and structure, as well as the temporal distribution of the dung beetles that reside in CEREZ, are analyzed. Monthly samplings were carried out between February 2013 and January 2014 using pitfall traps baited with dung of six mammal species that are kept in captivity inside the Miguel Álvarez del Toro Zoo (ZooMAT). An annotated checklist of 22 species grouped into 12 genera and six tribes of Scarabaeinae is presented. Onthophagus anthracinus, Canthon femoralis, Onthophagus landolti, and Copris laeviceps provide 89.7% of the total abundance. The rarefaction curve shows an asymptotic tendency, with 92% completeness. The captured fauna showed a marked temporal distribution (p < 0.01), observing the highest values of richness and abundance during the months of the rainy season. The records represent 7.53% of the species diversity known in Mexico and 18.2% of the reported in the Chiapas state. Despite representing a small remnant of tropical forest and the constant anthropic pressure generated by the urban area, El Zapotal conserves a representative fauna of dung beetles at the regional level, Highlighting the importance of the reserve as a refuge for species.

Benefits of fasting abbreviation with carbohydrates and omega-3 infusion during cabg: a double-blind controlled randomized trial

Abstract Objective: To assess postoperative clinical data considering the association of preoperative fasting with carbohydrate (CHO) loading and intraoperative infusion of omega-3 polyunsaturated fatty acids (ω-3 PUFA). Methods: 57 patients undergoing coronary artery bypass grafting (CABG) were randomly assigned to receive 12.5% maltodextrin (200 mL, 2 h before anesthesia), (CHO, n=14); water (200 mL, 2 h before anesthesia), (control, n=14); 12.5% maltodextrin (200 mL, 2 h before anesthesia) plus intraoperative infusion of ω-3 PUFA (0.2 g/kg), (CHO+W3, n=15); or water (200 mL, 2 h before anesthesia) plus intraoperative infusion of ω-3 PUFA (0.2 g/kg), (W3, n=14). The need for vasoactive drugs was analyzed, in addition to postoperative inflammation and metabolic control. Results: There were two deaths (3.5%). Patients in CHO groups presented a lower incidence of hospital infection (RR=0.29, 95% CI 0.09-0.94; P=0.023), needed fewer vasoactive drugs during surgery and ICU stay (P<0.05); and had better blood glucose levels in the first six hours of recovery (P=0.015), requiring less exogenous insulin (P=0.018). Incidence of postoperative atrial fibrillation (POAF) varied significantly among groups (P=0.009). Subjects who receive ω-3 PUFA groups had fewer occurrences of POAF (RR=4.83, 95% CI 1.56-15.02; P=0.001). Patients in the W3 group had lower ultrasensitive-CRP levels at 36 h postoperatively (P=0.008). Interleukin-10 levels varied among groups (P=0.013), with the highest levels observed in the postoperative of patients who received intraoperative infusion of ω-3 PUFA (P=0.049). Conclusion: Fasting abbreviation with carbohydrate loading and intraoperative infusion of ω-3 PUFA is safe and supports faster postoperative recovery in patients undergoing on-pump CABG.

Adolescentes com Diabetes Mellitus tipo 1: estresse, coping e adesão ao tratamento / Adolescents with Diabetes Mellitus 1: stress, coping and adhesion to treatment

Este estudo verificou as relações entre estressores do diabetes mellitus tipo 1 e seu enfrentamento e os comportamentos de autocuidados em 10 adolescentes, que responderam os seguintes instrumentos: Questionário Sociodemográfico, Summary of Diabetes Self-Care Activities Questionnaire, o Questionnaire on Stress in Patientes with Diabetes-Revised, Adolescent/Child's Self-Report Responses to Stress-Diabetes, todos com validação linguística, e a Escala de Coping do Diabetes para Adolescentes, baseada na Motivational Theory of Coping. Observou-se baixa adesão aos autocuidados. São principais estressores a hipoglicemia, o regime terapêutico e as queixas somáticas, os quais ameaçam a necessidade psicológica básica de Competência e geram raiva. Os adolescentes lidam com o regime terapêutico de forma mal adaptativa, diminuindo a adesão à atividade física. Estressores relacionados à ansiedade/depressão apresentaram maior número de correlações, especialmente com respostas de estresse involuntárias e de desengajamento. Essa análise das variáveis motivacionais do processo de adesão ao tratamento fornece dados prescritivos para intervenções com essa população

This study analyses the relationship between stress causes from diabetes mellitus I, coping and self-care behavior in 10 adolescents who answered the Sociodemographic Questionnaire, Summary of Diabetes Self-Care Activities Questionnaire, Questionnaire on Stress in Patients with Diabetes-Revised, Adolescent/Child's Self-Report Responses to Stress-Diabetes, with linguistic validation, and Coping Diabetes Scale for Adolescents, based on the Motivational Theory of Coping. Low self-caring adhesion was detected. Main stressors are hypoglycemia, therapy regime and body complaints, all of which threat the psychological basic need of competence and produced anger. Adolescents cope inadequately with the therapy regime and lessen adhesion to physical activities. Stress causes related to anxiety/depression had the greatest number of correlations, particularly involuntary responses to stress and disengagement. Current analysis of motivational variables of adhesion to treatment provides prescriptive data for interventions with the population concerned

Quality of life in the pre- and postoperative periods in spinal fusion and discectomy / Qualidade de vida pré e pós-operatória da artrodese de coluna e discectomia / Calidad de vida en los periodos pre y postoperatorio en artrodesis de columna y discectomía

ABSTRACT Objectives: Considering the epidemiological and functional importance of spinal pathologies and the large number of surgeries performed today, the study aimed to evaluate the impact of spinal arthrodesis and discectomy surgeries on patients' quality of life. Methods: This is a retrospective, descriptive, and longitudinal study developed in the neurology and neurosurgery department of a strategic tertiary hospital in an inland town in the state of São Paulo. Data were collected through a telephone interview, using the Oswestry questionnaire (ODI) to assess lumbar pain in patients submitted to surgery in 2014 and 2015. Results: There was an improvement in the ODI results in all the periods analyzed. When the evaluations were subdivided by surgical type, there was an absolute improvement in the median ODI results in all procedures, however, only the cervical spine arthrodesis procedure was not statistically significant, probably due to the low number of procedures analyzed (n = 12). Conclusion: It can be concluded that the current surgical technique can contribute to the improvement of patients' quality of life. Level of Evidence III; Comparative retrospective study.

Cambios en la comunidad de peces por efecto del desarrollo costero en el Parque Nacional Huatulco (México) / Changes in fish communities from the effect of coastal development in Huatulco National Park (Mexico)

Resumen El incremento del aporte de sedimentos desde tierra derivado del desarrollo costero y urbanización ha producido efectos adversos en la estructura y función de los arrecifes coralinos. El objetivo de este estudio fue conocer la magnitud de disturbios por aportes excesivos de sedimentos en la comunidad íctica de arrecifes coralinos de las bahías Maguey y Violín del Parque Nacional Huatulco (México). Los muestreos de peces se realizaron antes y después de disturbios ocasionados por aportes de sedimentos asociados a obras de desarrollo costero. Como indicadores de cambios en las comunidades de peces se utilizaron el número de especies, diversidad, equidad y dominancia antes y después de la perturbación. El análisis se realizó mediante pruebas de comparación de medias, análisis de similitud (ANOSIM) y análisis de porcentaje de similitud (SIMPER). En ambas localidades, se observó, que, excepto la dominancia, la diversidad, equidad, abundancia y número de especies fueron mayores previos a la perturbación. En Maguey se observaron diferencias significativas en la equidad y dominancia (U=28, p=0.0401; U=24, p=0.0472), así como en la composición de especies y la abundancia (ANOSIM=0.35, p=0.009). El análisis de porcentaje de similitud (SIMPER) indicó que posterior a la perturbación, el 46 % de especies presentaron una disminución en su abundancia, destacó la ausencia de Prionurus laticlavius, así como el decremento en la abundancia de: P. punctatus, Cirrhitichthys oxycephalus, Microspathodon dorsalis, Lutjanus novemfaciatus y Stegates acapulcoensis. La inadecuada planeación y ejecución de proyectos de desarrollo costero que propiciaron aporte excesivo de sedimentos al mar determinaron cambios negativos en las comunidades coralinas de Maguey y Violín, cuyo efecto fue observado en la composición de especies, abundancia, equidad y dominancia de la comunidad de peces de Maguey.(AU)

Abstract Coastal development and urbanization have increased the sediments that are washed from the land surface, producing adverse effects on the structure and functioning of coral reefs. The objective of this study was to identify the degree to which excessive sediments have disturbed the fish community in the coral reefs in the Maguey and Violin bays, located in the Huatulco National Park (Mexico). Fish samples were collected before and after disturbances produced by sediments associated with coastal development projects. Indicators of changes in the fish communities included the number and diversity of species as well as equity and dominance before and after the disturbances. The analysis was performed through means comparison tests, similarity analysis (ANOSIM) and similarity percentage analysis (SIMPER). In both locations, it was observed that the diversity, evenness, abundance and number of species were higher prior to the disturbance, but not for dominance, which shows an inverse pattern. In Maguey, significant differences in evenness and dominance were observed (U = 28, p = 0.0401; U = 24, p = 0.0472), as well as in species composition and abundance (ANOSIM = 0.35, p = 0.009). The similarity percentage analysis (SIMPER) indicated that after the disturbance, more than 46 % of the species showed decreases in average abundance, highlighting the absence of Prionurus laticlavius, as well as the decrease in abundance of: P. punctatus, Cirrhitichthys oxycephalus, Microspathodon dorsalis, Lutjanus novemfaciatus and Stegates acapulcoensis. Inadequate planning and implementation of coastal development projects that contribute to the discharge of excessive sediments into the sea were determinants of negative changes in the coral communities in Maguey and Violin, whose effects could be seen in the composition of the species and the abundance, equity, and dominance of the fish community in Maguey.(AU)

Extended-time of noninvasive positive pressure ventilation improves tissue perfusion after coronary artery bypass surgery: a randomized clinical trial

Abstract Objective: To compare the effects of extended- versus short-time noninvasive positive pressure ventilation on pulmonary function, tissue perfusion, and clinical outcomes in the early postoperative period following coronary artery bypass surgery in patients with preserved left ventricular function. Methods: Patients were randomized into two groups according to noninvasive positive pressure ventilation intensity: short-time noninvasive positive pressure ventilation n=20 (S-NPPV) and extended-time noninvasive positive pressure ventilation n=21 (E-NPPV). S-NPPV was applied for 60 minutes during immediate postoperative period and 10 minutes, twice daily, from postoperative days 1-5. E-NPPV was performed for at least six hours during immediate postoperative period and 60 minutes, twice daily, from postoperative days 1-5. As a primary outcome, tissue perfusion was determined by central venous oxygen saturation and blood lactate level measured after anesthetic induction, immediately after extubation and following noninvasive positive pressure ventilation protocols. As a secondary outcome, pulmonary function tests were performed preoperatively and in the postoperative days 1, 3, and 5; clinical outcomes were recorded. Results: Significant drop in blood lactate levels and an improvement in central venous oxygen saturation values in the E-NPPV group were observed when compared with S-NPPV group after study protocol (P<0.01). The E-NPPV group presented higher preservation of postoperative pulmonary function as well as lower incidence of respiratory events and shorter postoperative hospital stay (P<0.05). Conclusion: Prophylactic E-NPPV administered in the early postoperative period of coronary artery bypass surgery resulted in greater improvements in tissue perfusion, pulmonary function and clinical outcomes than S-NPPV, in patients with preserved left ventricular function.

Ecografía pulmonar como herramienta diagnóstica de neumonía adquirida en la comunidad en niños / Pulmonary echography as a diagnostic tool of pneumonia acquired in the community in children

Resumen La neumonía se define clínicamente como la presencia aguda de fiebre acompañada de síntomas y signos respiratorios que pueden estar o no acompañados de hallazgos radiográficos. Sin embargo, los signos y síntomas que acompañan la enfermedad en la edad pediátrica son inespecíficos. La radiografía de tórax continúa siendo la prueba de referencia para el diagnóstico de neumonía. Contrario a esto, la radiografía de tórax no se recomienda de forma rutinaria ante la sospecha de neumonía. La tomografía y la resonancia magnética ofrecen mejores herramientas diagnósticas, aunque todas conllevan a una exposición a radiación ionizante y a un mayor costo en los servicios de salud. Es conocido que la radiación ionizante es capaz de causar potencialmente daños a los tejidos y más aún en los niños. En los últimos años, diferentes estudios proponen la ecografía pulmonar como ayuda diagnóstica para la neumonía al ofrecer ventajas como no requerir uso de sedantes, no expone a radiación ionizante, fácil transporte y ofrece mejor resolución en lo referente al diagnóstico de septos. Muchos estudios han demostrado la efectividad de la ecografia pulmonar para el diagnóstico de la neumonía. Un metaanálisis reciente reportó una sensibilidad de 96 % (IC95 % 94-97 %) y una especificidad del 93 % (IC95 % 90-96 %) de la ecografía pulmonar para el diagnóstico para la neumonía. Deduciendo que la ecografía pulmonar se proyecta como una herramienta diagnóstica para la neumonía, llegando a ser igual o superior a la radiografía de tórax.

Abstract Pneumonia is defined clinically as the acute presence of fever accompanied by respiratory symptoms and signs that may or may not be accompanied by radiographic findings. However, the signs and symptoms that accompany the disease in the pediatric age are nonspecific. Chest radiography continues to be the gold standard for the diagnosis of pneumonia. Contrary to this, chest radiography is not routinely recommended in case of suspected pneumonia. The tomography and the magnetic resonance offer better diagnostic tools, nevertheless these, along with the x-ray, lead to an exposure to ionizing radiation and to a greater cost in the health services. It is known that ionizing radiation is capable of potentially causing damage to tissues and even more so in children. In recent years, different studies have proposed pulmonary ultrasound as a diagnostic aid for pneumonia, offering advantages such as not requiring the use of sedatives, exposure to ionizing radiation, easy transport and offering better resolution regarding the diagnosis of septa. Many studies have demonstrated the effectiveness of pulmonary ultrasound for the diagnosis of pneumonia. A recent meta-analysis reported a sensitivity of 96% (95% CI 94-97%) and a specificity of 93% (95% CI 90-96%) for pulmonary ultrasound for the diagnosis of pneumonia. Deducing that the pulmonary ultrasound is projected as a diagnostic tool for pneumonia, being equal or superior to chest radiography.
