Resumo Durante a pandemia do COVID-19, mudanças ocorreram em diversos campos, fazendo-se importante conhecer os contextos de risco social e psíquico que marcam condições de vulnerabilidade e vulneração, vividas por crianças e bebês, a despeito de crianças: refugiadas, residentes em favela e crianças vítimas de violência intrafamiliar. Objetivo: Conhecer possíveis riscos à saúde mental de crianças, em situação de vulnerabilidade, no período da pandemia de Covid-19, na realidade brasileira. Método: Estudo de mídia, com vistas à análise do contexto sociopolítico, favorecendo a visão crítica de leituras de mundo distintas, fundamental para compreensão do objeto pretendido. Resultado: A partir dos dados levantados, estruturou-se categorias específicas à cada grupo estudado, a saber: 1) crianças refugiadas: precariedade do abrigo; dimensão legal; perdas e lutos; e xenofobia. 2) crianças residentes periféricas: perdas e lutos; violência à criança; acesso à saúde; e fome. 3) violência intrafamiliar: direitos da criança em situação de violência; violência doméstica na pandemia e meios extradomiciliares que amparam a criança. Os resultados obtidos em cada um dos objetivos específicos, denunciam especificidades de cada um dos grupos: as crianças refugiadas, além de perderem direitos vivenciam perda da sua origem, dificultando o endereçamento do seu sofrimento a um “outro”. As crianças residentes em periferias, além de serem afetadas pela pandemia, sofreram efeitos da necropolitica, advinda da herança colonial. Crianças vítimas de violência intrafamiliar enfrentaram agravos decorrentes do isolamento social e adoecimnto psíquico dos cuidadores. Considera-se, por fim que sem a denúncia necessária, os riscos de esquecimento de tão grave problemática pode se fazer efetivar e os recursos necessários ao cuidado não se fazerem urgentes. A análise da mídia favoreceu lidar com uma lacuna no campo científico, possibilitando a criação de reflexões da condição de vulneração de populações invisibilizadas.

Abstract During the COVID-19 pandemic, changes occurred in several fields, making it important to know the contexts of social and psychic risk that mark conditions of vulnerability and vulnerability, experienced by children and babies, despite children: refugees, residents in favelas and children’s victims of domestic violence. Objective: To know possible risks to the mental health of children, in a situation of vulnerability, in the period of the Covid-19 pandemic, in the Brazilian reality. Method: Media study, with a view to analyzing the sociopolitical context, favoring a critical view of different world readings, fundamental for understanding the intended object. Result: From the collected data, specific categories were structured for each group studied, namely: 1) refugee children: precariousness of the shelter; legal dimension; losses and mourning; and xenophobia. 2) children living in peripheral areas: losses and bereavements; child violence; access to health; and hunger. 3) domestic violence: rights of children in situations of violence; domestic violence in the pandemic and extra-domiciliary means that support the child. The results obtained in each of the specific objectives, denounce specificities of each of the groups: refugee children, in addition to losing rights, experience the loss of their origin, making it difficult to address their suffering to an “other”. Children residing in peripheries, in addition to being affected by the pandemic, suffered the effects of necropolitics, arising from the colonial heritage. Children victims of intrafamily violence faced injuries resulting from social isolation and mental illness of caregivers. Finally, it is considered that without the necessary denouncement, the risks of forgetting such a serious problem can become effective and the resources necessary for care do not become urgent. Media analysis favored dealing with a gap in the scientific field, enabling the creation of reflections on the vulnerable condition of invisible populations.

Resumo Durante o presente estudo, o estresse oxidativo mediado pelo cobre (Cu) foi medido que induziu danos ao DNA por concentração nos tecidos de peixes, Catla catla (14,45 ± 1,24g; 84,68 ± 1,45mm) (Hamilton, 1822). Os alevinos foram retidos em 5 grupos por 14, 28, 42, 56, 70 e 84 dias do período de exposição. Eles foram tratados com 2/3, 1/3, 1/4 e 1/5 (T1-T4) de 96h de concentração letal de cobre. Os controles foram executados junto com todos os tratamentos para as mesmas durações. Uma significativa (p <0,05) concentração dependente do tempo e da dose de Cu foi observada nas brânquias, fígado, rim, músculos e cérebro de C. catla. Entre os órgãos, o fígado apresentou uma concentração significativamente maior de cobre, seguido por guelras, rins, cérebro e músculos. O acúmulo de cobre nesses órgãos causou uma variação significativa nas atividades das enzimas viz. superóxido dismutase (SOD), catalase (CAT) e peroxidase (POD). A atividade de SOD variou significativamente em resposta ao tempo de exposição de Cu como 56> 70> 42> 84> 28> 14 dias, enquanto a atividade de CAT exibiu uma relação inversa com o aumento na concentração de Cu. A atividade POD mostrou um aumento significativo com um aumento na duração da exposição ao Cu. O ensaio do cometa exibiu dano significativo ao DNA induzido por Cu nos eritrócitos periféricos de C. catla. Entre as quatro concentrações de exposição, 2/3 do LC50 (T1) causou danos significativamente maiores aos núcleos em comparação com o controle. O aumento da atividade de POD e SOD, bem como uma diminuição na atividade de CAT em resposta ao Cu, demonstra o envolvimento de um mecanismo protetor contra espécies reativas de oxigênio (ROS), enquanto o aumento de ROS resultou em maior dano ao DNA. Esses marcadores moleculares mencionados acima podem ser usados de forma eficiente para o biomonitoramento de ambientes aquáticos e conservação da ictiofauna comestível.

Abstract During present study, the copper (Cu) mediated oxidative stress was measured that induced DNA damage by concentrating in the tissues of fish, Catla catla (14.45±1.24g; 84.68±1.45mm) (Hamilton,1822). Fish fingerlings were retained in 5 groups for 14, 28, 42, 56, 70 and 84 days of the exposure period. They were treated with 2/3, 1/3, 1/4 and 1/5 (T1-T4) of 96h lethal concentration of copper. Controls were run along with all the treatments for the same durations. A significant (p < 0.05) dose and time dependent concentration of Cu was observed in the gills, liver, kidney, muscles, and brain of C. catla. Among organs, the liver showed a significantly higher concentration of Cu followed by gills, kidney, brain, and muscles. Copper accumulation in these organs caused a significant variation in the activities of enzymes viz. superoxide dismutase (SOD), catalase (CAT) and peroxidase (POD). The SOD activity varied significantly in response to the exposure time of Cu as 56 > 70 > 42 > 84 > 28 > 14 days while CAT activity exhibited an inverse relationship with the increase in Cu concentration. POD activity showed a significant rise with an increase in Cu exposure duration. Comet assay exhibited significant DNA damage in the peripheral erythrocytes of Cu exposed C. catla. Among four exposure concentrations, 2/3rd of LC50 (T1) caused significantly higher damage to the nuclei compared to control. Increased POD and SOD activity, as well as a decrease in CAT activity in response to Cu, demonstrates the involvement of a protective mechanism against reactive oxygen species (ROS), whereas increased ROS resulted in higher DNA damage. These above-mentioned molecular markers can be efficiently used for the biomonitoring of aquatic environments and conservation of edible fish fauna.

Abstract Violence is a serious public health issue and constitutes a historical social phenomenon with diverse causes and consequences, and multiple manifestations. The main victims continue to be populations left vulnerable and marginalised, where dimensions including gender, class, race and social belonging intersect. Although studies to explain the phenomenon of violence do address ethnic and racial issues, they tend not to consider violence as stemming also from institutional racism. This paper examines data from a qualitative and quantitative study drawing on focus groups and semi-structured interviews to evaluate symbolic and structural violence experienced by young black people from 15 to 29 years old residing in peripheral neighbourhoods of two Brazilian state capitals - Recife and Fortaleza. The focus is on their standpoints that situate the intersectionality, especially among race/skin colour, territorial belonging and class, in the very definition of identity. In both capitals, the young black people revealed a common reality: life projects constrained by economic limitations and by the concrete or symbolic demarcation of social spaces to which they are denied access.

Resumo A violência é um grave problema de saúde pública e constitui um fenômeno sócio-histórico, com causas e consequências diversas e múltiplas expressões. As principais vítimas seguem sendo as populações vulnerabilizadas e periféricas, nas quais se interseccionam dimensões como gênero, classe, raça e pertencimento social. Embora as questões étnico-raciais estejam presentes nos estudos que explicam o fenômeno da violência, estes tendem a não a considerar também fruto do racismo institucional. Este artigo pretende analisar dados de uma pesquisa quali-quanti que avaliou experiências de violência simbólica e estrutural vivenciadas por jovens negros/as de 15 a 29 anos de idade e moradores/as de bairros periféricos de duas capitais brasileiras - Recife e Fortaleza, a partir de grupos focais e entrevistas semiestruturadas. Foram enfatizados os lugares de fala que situavam a interseccionalidade, sobretudo de raça/cor da pele, pertencimento territorial e classe, na própria definição identitária. Em ambas as capitais a juventude negra trouxe à tona uma realidade comum: um horizonte limitado na definição de projetos de vida, tanto por questões econômicas quanto da demarcação concreta ou simbólica de lugares sociais para os quais seu acesso é interditado.

ABSTRACT Introduction: There is no consensus on the impact of coronary artery disease in patients undergoing transcatheter aortic valve implantation. Therefore, the objective of this study was, in a single-center setting, to evaluate the five-year outcome of transcatheter aortic valve implantation patients with or without coronary artery disease. Methods: All transcatheter aortic valve implantation patients between 2009 and 2019 were included and grouped according to the presence or absence of coronary artery disease. The primary endpoint, five-year all-cause mortality, was evaluated using Cox regression adjusted for age, sex, procedure years, and comorbidities. Comorbidities interacting with coronary artery disease were evaluated with interaction tests. In-hospital complications was the secondary endpoint. Results: In total, 176 patients had aortic stenosis and concomitant coronary artery disease, while 170 patients had aortic stenosis only. Mean follow-up was 2.2±1.6 years. There was no difference in the adjusted five-year all-cause mortality between transcatheter aortic valve implantation patients with and without coronary artery disease (hazard ratio 1.00, 95% confidence interval 0.59-1.70, P=0.99). In coronary artery disease patients, impaired renal function, peripheral arterial disease, or ejection fraction < 50% showed a significant interaction effect with higher five-year all-cause mortality. No significant differences in complications between the groups were found. Conclusion: Five-year mortality did not differ between transcatheter aortic valve implantation patients with or without coronary artery disease. However, in patients with coronary artery disease and impaired renal function, peripheral arterial disease, or ejection fraction < 50%, we found significantly higher five-year all-cause mortality.

ABSTRACT Objective: To compare and analyze pulmonary function and respiratory mechanics parameters between healthy children and children with cystic fibrosis. Methods: This cross-sectional analytical study included healthy children (HSG) and children with cystic fibrosis (CFG), aged 6–13 years, from teaching institutions and a reference center for cystic fibrosis in Florianópolis/SC, Brazil. The patients were paired by age and sex. Initially, an anthropometric evaluation was undertaken to pair the sample characteristics in both groups; the medical records of CFG were consulted for bacterial colonization, genotype, and disease severity (Schwachman-Doershuk Score — SDS) data. Spirometry and impulse oscillometry were used to assess pulmonary function. Results: In total, 110 children were included, 55 in each group. In the CFG group, 58.2% were classified as excellent by SDS, 49.1% showed the ΔF508 heterozygotic genotype, and 67.3% were colonized by some pathogens. Statistical analysis revealed significant differences between both groups (p<0.05) in most pulmonary function parameters and respiratory mechanics. Conclusions: Children with cystic fibrosis showed obstructive ventilatory disorders and compromised peripheral airways compared with healthy children. These findings reinforce the early changes in pulmonary function and mechanics associated with this disease.

RESUMO Objetivo: Comparar e analisar parâmetros de função pulmonar e de mecânica respiratória entre escolares saudáveis e com fibrose cística (FC). Métodos: Estudo transversal que incluiu escolares saudáveis (GES) e com FC (GFC), com idades entre seis e 13 anos, provenientes de instituições de ensino e de um centro de referência da FC em Florianópolis/SC, Brasil, pareados por idade e sexo, respectivamente. Inicialmente, conduziu-se avaliação antropométrica para pareamento e caracterização de ambos os grupos e, no GFC, consultou-se prontuário médico para registro dos dados de colonização bacteriana, genótipo e gravidade da doença (Escore de Schwachman-Doershuk — ESD). Para a avaliação da função pulmonar, realizou-se espirometria e a avaliação da mecânica respiratória foi conduzida por meio do sistema de oscilometria de impulso. Resultados: Participaram 110 escolares, 55 em cada grupo. No GFC, 58,2% foram classificados pelo ESD como excelentes, 49,1% apresentaram genótipo ∆F508 heterozigoto e 67,3% eram colonizados por alguma patógeno. Houve diferença significativa (p<0,05) na maioria dos parâmetros de função pulmonar e de mecânica respiratória entre os grupos. Conclusões: Escolares com FC apresentaram distúrbio ventilatório obstrutivo e com comprometimento de vias aéreas periféricas, em comparação aos escolares hígidos. Esse evento reforça o início precoce da alteração de função pulmonar e de mecânica respiratória nessa enfermidade, evidenciados pelos achados desta investigação.

ABSTRACT: The objective of the present study was to evaluate clinical, cardiorespiratory, and Doppler echocardiographic changes in rabbits sedated with midazolam and morphine combined with or without dexmedetomidine. This study was a blinded, randomized, controlled experiment that included 16 adult male New Zealand rabbits weighing 3.1 ± 0.3 kg. The animals were sedated using one of the following protocols: 1 mg/kg midazolam and 2 mg/kg morphine (MIDA, n = 8), or 25 mg/kg dexmedetomidine, 2 mg/kg morphine and 1 mg/kg midazolam (DEX, n = 8). Sedation latency, duration of the sedation and recovery period, sedation scores, heart rate (HR), respiratory rate (f), peripheral oxygen saturation (SpO2), systolic arterial pressure (SAP), diastolic arterial pressure (DAP), mean arterial pressure (MAP), and recta temperature were recorded, and Doppler echocardiography was performed. Latency periods were 7.3±1.6 min in the DEX group and 10.9 ± 5.0 min in the MIDA group (P = 0.112). Sedation duration was 122.4±14 min in the DEX group and 71.2 ± 32 min in the MIDA group (P = 0.005), whereas recovery time was 35.7±17.7 min in the DEX group and 32.5 ± 25.3 min in the MIDA group (P = 0.743). The sedation scores for the DEX group were significantly higher than those for the MIDA group throughout the monitoring period. Reductions in HR, SAP, MAP, and DAP values were observed in both groups relative to baseline values, and were significantly lower in the DEX group compared to the MIDA group. Minimal Doppler echocardiographic changes were observed. Dexmedetomidine used in combination with midazolam and morphine incremented the quality and duration of sedation in rabbits. Both protocols elicited cardiorespiratory changes that were well-tolerated, with minimal changes in myocardial function.

RESUMO: O objetivo do presente estudo foi avaliar alterações clínicas, cardiorrespiratórias e ecodopplercardiográficas, bem como o nível de sedação em coelhos sedados com midazolam e morfina combinadas, ou não, com dexmedetomidina. O design do estudo foi experimental controlado randomizado cego, com 16 coelhos adultos machos Nova Zelândia, pesando 3,1 ± 0,3 Kg. Os animais foram sedados aleatoriamente com um dos seguintes tratamentos: MIDA (n = 8): 1 mg/kg de midazolam e 2 mg/kg de morfina; DEX (n = 8) 25 mcg/kg de dexmedetomidina, 2 mg/kg de morfina e 1 mg/kg de midazolam; Latência, sedação e períodos de recuperação, escores de sedação, FC, f, SpO2, PAS, PAM, PAD, ToC, foram mensurados e ecoDopplercardiografia foi realizada. Os períodos de latência foram 7.3 ± 1.6 minutos no grupo DEX e 10.9 ± 5.0 minutos no grupo MIDA (P = 0,112). A duração da sedação foi de 122.4 ± 14 minutos no grupo DEX e 71.2 ± 32 minutos no grupo MIDA (P = 0,005). Os tempos totais de recuperação foram de 35.7 ± 17.7 minutos no grupo DEX e 32.5 ± 25.3 minutos no MIDA (P = 0,743). Os escores de sedação obtidos do grupo DEX foram estatisticamente superiores aos do grupo MIDA durante todas as observações (de 5 a 40 minutos). A redução dos valores de FC, PAS, PAM e PAD foi observada em ambos os grupos, em relação ao momento baseline, e foram significativamente menores no grupo DEX quando comparado ao MIDA. Alterações ecodopplercardiográficas mínimas foram observadas ambos os grupos. A adição de dexmedetomidina à associação midazolam/morfina aumentou o nível, a qualidade e a duração do protocolo sedativo. Ambos os protocolos causaram alterações cardiorrespiratórias bem toleradas em animais normais e com mínimas alterações na função miocárdica.

ABSTRACT Purpose: This study aimed to compare four depths of manual dissection for the preparation of Descemet stripping endothelial keratoplasty lamellae. Methods: Eye bank corneas were randomized into four groups according to dissection depths: Pachy-100 (incision depth = central corneal thickness-safety margin of 100 µm), Pachy-50 (safety margin of 50 µm), Pachy-0 (no safety margin), and Pachy+50 (incision depth = central corneal thickness + 50 µm). All endothelial lamellae were prepared using a standardized method of manual dissection (Pachy-DSEK). The central, paracentral (3.0-mm zone), and peripheral (6.0-mm zone) lamella thicknesses and incision depths were measured by optical coherence tomography. The 3.0-mm and 6.0-mm zone central-to-peripheral thickness ratios were calculated. Results: Endothelial perforation occurred only in the Pachy+50 group (n=3, 30%). Central lamella’s thickness in Pachy-100, Pachy-50, Pachy-0, and Pachy+50 groups measured 185 ± 42 µm, 122 ± 29 µm, 114 ± 29 µm, and 58 ± 31 µm, respectively (p<0.001). The overall 3.0- and 6.0-mm C/P ratios were 0.97 ± 0.06 and 0.92 ± 0.14, respectively. Preoperative donor characteristics were not correlated with most thickness outcomes. The planned incision depth correlated significantly with most lamella’s thickness parameters (p<0.001). The overall thickness of the lamella negatively correlated with the planned incision depth (p<0.001, r=-0.580). The best outcome was found in the Pachy-0 group, as 75% of the lamellae measured <130 µm and there was no endothelial perforation. Conclusions: By using a standardized method of dissection, most manually prepared lamellae presented a planar shape. Setting the incision depth to the central corneal thickness did not result in endothelial perforation and a high percentage of ultrathin lamellae was achieved.

RESUMO Objetivo: Comparar quatro profundidades de dissecção manual usadas no preparo de lamelas para transplante endotelial. Métodos: Córneas humanas de treinamento disponibilizadas foram randomizadas em quatro grupos: Pachy-100 (profundidade de incisão = espessura corneana central - margem de segurança de 100 µm), Pachy-50 (margem de segurança de 50 µm), Pachy-0 (sem margem de segurança) e Pachy+50 (profundidade de incisão = espessura corneana central + 50 µm). Todas as lamelas foram dissecadas através um método padronizado e já publicado (Pachy-DSEK). As espessuras das lamelas (centro, zona de 3,0mm e zona de 6,0mm) foram medidas com tomografia de coerência óptica. A razão de espessura centro-periferia foi calculada aos 3,0 e 6,0 mm de diâmetro. Resultados: Perfuração endotelial ocorreu apenas no grupo Pachy+50 (n=3, 30%). A espessura central da lamela nos grupos Pachy-100, Pachy-50, Pachy-0 e Pachy+50 foi de 185 ± 42 µm, 122 ± 29 µm, 114 ± 29 µm, e 58 ± 31 µm, respectivamente (p<0,001). As razões C/P aos 3,0 e 6,0 mm foram de 0,97 ± 0,06 e 0,92 ± 0,14, respectivamente. Os parâmetros de características do doador não se correlacionaram com os resultados de espessura de lamela. A profundidade planejada de incisão se correlacionou com a maioria dos parâmetros de espessura de lamela (p<0,001). A espessura de lamela se correlacionou negativamente com a profundidade planejada da incisão (p<0.001, r=-0,580). O melhor resultado foi observado no grupo Pachy-0, em que 75% das lamelas mediram abaixo de 130 µm e não houve perfuração endotelial. Conclusão: Através de um método padronizado de dissecção, a maioria das lamelas endoteliais apresentou uma configuração planar. O planejamento de profundidade de incisão igual à espessura corneana central resultou em alta porcentagem de lamelas ultrafinas sem ocorrência de perfuração.

Resumen Analizar el espacio escolar desde una perspectiva interseccional de género implica ir más allá de su enfoque como contexto de interacción entre niños y jóvenes, reconociendo que el espacio y las identidades sociales se constituyen mutuamente, es decir, el espacio es un reflejo de las relaciones de poder hegemónicas y, simultáneamente, de su concepción y la experiencia perpetúan diversas formas de desigualdades. De esta manera, este artículo pretende abordar la escuela desde una perspectiva interseccional de género, colocando la dimensión espacial en el centro de los análisis de la pluralidad de formas en que alumnos y alumnas ocupan y experimentan sus diferentes lugares. Con el fin de valorar las perspectivas de los estudiantes sobre sus propias experiencias en el espacio escolar, se presenta el mapeo participativo como una herramienta de investigación, habiendo sido aplicado en tres grupos escolares ubicados en la ciudad de Lisboa, en Portugal. Los resultados obtenidos a través de este instrumento permiten realizar un análisis respecto de la pluralidad de masculinidades y feminidades existentes en la escuela, cuyos marcadores de género y origen nacional son relevantes para comprender la forma en que se identifican los diferentes grupos de estudiantes. También se discute cómo se produce la interacción entre diferentes nacionalidades y su papel en la dinámica socio espacial en la escuela a partir de tres procesos: la laterización cultural, la guetización del espacio escolar y la ocupación periférica del patio de recreo por parte de las estudiantes. jóvenes mutuamente decir simultáneamente desigualdades manera lugares investigación Lisboa Portugal procesos cultural

Abstract Analyzing the school space from an intersectional gender perspective implies going beyond its approach as a context of interaction between children and young people, recognizing that space and social identities are mutually constituted. In other words, space reflects hegemonic power relations and, simultaneously, its conception and experience perpetuate various forms of inequality. This article approaches school, from an intersectional perspective, placing the spatial dimension at the center of analyzes of the plurality of ways in which students occupy and experience different places. The experiences of students and their experiences in the school space are captured and understood using participatory mapping as an analysis methodology, applied, to three school groups located in the city of Lisbon, in Portugal. The results reveal the advantages of the methodology in analyzing the plurality of masculinities and femininities at school, revealing how gender and national origin are relevant to understanding the way in which groups of students create a distinct identity and are identified. Participatory mapping also proves to be an appropriate methodology for analyzing interaction processes between students of different nationalities and the role of these processes in the formation of socio-spatial dynamics at school, through three mechanisms: cultural laterization, the ghettoization of the school space and the peripheral occupation of the sports court by the feminine students. people constituted words simultaneously inequality places applied Lisbon Portugal identified sociospatial socio mechanisms laterization

Resumo Analisar o espaço escolar sob uma perspetiva interseccional de gênero implica ir além da sua abordagem enquanto contexto de interação entre crianças e jovens, reconhecendo que o espaço e as identidades sociais se constituem mutuamente. Por outras palavras, o espaço é um reflexo das relações de poder hegemônicas e, simultaneamente, a sua conceção e vivência perpetuam diversas formas de desigualdade. Neste artigo aborda-se a escola a partir de uma perspetiva interseccional, colocando a dimensão espacial no centro das análises da pluralidade de modos com que alunos e alunas ocupam e experienciam diferentes lugares. As experiências de estudantes e as suas vivências no espaço escolar são captadas e compreendidas com recurso ao mapeamento participativo como metodologia de análise, aplicando-a em três agrupamentos escolares localizados na cidade de Lisboa, em Portugal. Os resultados demonstraram as vantagens da metodologia na análise da pluralidade de masculinidades e feminilidades na escola, revelando como o gênero e a origem nacional são relevantes para a compreensão da maneira como os grupos de estudantes criam uma identidade distinta e são identificados. O mapeamento participativo também se revela uma metodologia adequada para analisar os processos de interação entre estudantes de diferentes nacionalidades e o papel desses processos na formação de dinâmicas socioespaciais na escola, através de três mecanismos: laterização cultural, guetização do espaço escolar e ocupação periférica do campo de jogos pelas alunas. jovens mutuamente palavras simultaneamente desigualdade abordase aborda lugares aplicandoa aplicando Lisboa Portugal identificados mecanismos cultural

Resumen: En | Texto: En | PDF: En

Abstract Background: Pain management in hip fracture patients is of great importance for reducing postoperative morbidity and mortality. Multimodal techniques, including peripheral nerve blocks, are preferred for postoperative analgesia. Older-old hip fracture patients with high ASA scores are highly sensitive to the side effects of NSAIDs and opioids. Our aim was to investigate the effectiveness of the recently popularized Supra-Inguinal Fascia Iliaca Block (SIFIB) in this population. Methods: Forty-one ASA III-IV patients who underwent SIFIB + PCA (G-SIFIB) or PCA alone (Group Control: GC) after general anesthesia were evaluated retrospectively. In addition to 24-hour opioid consumption, Visual Analog Scale (VAS) scores, opioid-related side effects, block-related complications, and length of hospital stay were compared. Results: Twenty-two patients in G-SIFIB and 19 patients in GC were evaluated. The postoperative 24-hour opioid consumption was lower in G-SIFIB than in GC (p < 0.001). There was a statistically significant reduction in VAS scores at the postoperative 1st, 3rd, and 6th hours at rest (p < 0.001) and during movement (p < 0.001 for the 1st and 3rd hours, and p = 0.02 for the 6th hour) in G-SIFIB compared to GC. There was no difference in pain scores at the 12th and 24th hours postoperatively. While there was no difference between the groups in terms of other side effects, respiratory depression was significantly higher in GC than in G-SIFIB (p = 0.01). Conclusion: The SIFIB technique has a significant opioid-sparing effect and thus reduces opioid-related side effects in the first 24 hours after hip fracture surgery in older-old patients.

Resumen Introducción: el progreso en los tratamientos para el lupus eritematoso sistémico (LES) resultó en una disminución de la mortalidad; sin embargo, la enfermedad cardiovascular y las complicaciones infecciosas aún son las principales causas de muerte. La evidencia apoya la participación del sistema inmunológico en la generación de la placa aterosclerótica, así como su conexión con las enfermedades autoinmunes. Objetivos: describir la frecuencia de eventos cardiovasculares (ECV) en el Registro de Lupus Eritematoso Sistémico de la Sociedad Argentina de Reumatología (RELESSAR) transversal, así como sus principales factores de riesgo asociados. Materiales y métodos: estudio descriptivo y transversal para el cual se tomaron los pacientes ingresados en el registro RELESSAR transversal. Se describieron las variables sociodemográficas y clínicas, las comorbilidades, score de actividad y daño. ECV se definió como la presencia de al menos una de las siguientes patologías: enfermedad arterial periférica, cardiopatía isquémica o accidente cerebrovascular. El evento clasificado para el análisis fue aquel posterior al diagnóstico del LES. Se conformaron dos grupos macheados por edad y sexo 1:2. Resultados: 1515 pacientes mayores de 18 años participaron del registro. Se describieron 80 pacientes con ECV (5,3%). En este análisis se incluyeron 240 pacientes conformando dos grupos. La edad media fue de 47,8 (14,4) y 47,6 (14,2) en el grupo con y sin ECV respectivamente. Los pacientes con ECV tuvieron mayor duración del LES en meses, mayor índice de Charlson, mayor SLICC (Systemic Lupus International Collaborating Clinics/American College of Rheumatology), mayor frecuencia de manifestaciones neurológicas, síndrome antifosfolípido, hospitalizaciones y uso de ciclofosfamida. Las únicas variables asociadas en el análisis multivariado fueron el índice de Charlson (p=0,004) y el SLICC (p<0,001). Conclusiones: los ECV influyen significativamente en nuestros pacientes, y se asocian a mayor posibilidad de daño irreversible y comorbilidades.

Abstract Introduction: progress in treatments for systemic lupus erythematosus (SLE) has resulted in a decrease in mortality; however, cardiovascular and infectious diseases remain the leading causes of death. Evidence supports the involvement of the immune system in the generation of atherosclerotic plaque, as well as its connection to autoimmune diseases. Objectives: to describe the frequency of cardiovascular disease (CVD) in the cross-sectional RELESSAR registry, as well as its associated variables. Materials and methods: a descriptive and cross-sectional study was performed using patients admitted to the cross-sectional RELESSAR registry. Sociodemographic variables, clinical variables, comorbidities, activity and damage scores were described. CVD was defined as at least one of the following: peripheral arterial disease, ischemic heart disease, or cerebrovascular accident. All patients with at least one CVD were included in our analysis (heart attack, central nervous system vascular disease, and peripheral arteries atherosclerotic disease). The event classified for the analysis was that after the diagnosis of SLE. SLE diagnosis was previous to CVD. Two groups matched by age and sex, 1:2 were formed. Results: a total of 1515 patients older than 18 years participated in the registry. Eighty patients with CVD (5.3%) were described in the registry. Two-hundred and forty patients were included, according to two groups. The mean age was 47.8 (SD 14.4) and 47.6 (SD 14.2) in patients with and without CVD, respectively. Patients with CVD had a longer duration of SLE in months, a higher Charlson index, a higher SLICC, increased frequency of neurological manifestations, antiphospholipid syndrome, hospitalizations, and use of cyclophosphamide. The associated variables in the multivariate were the Charlson Index (p=0.004) and the SLICC (p<0.001). Conclusions: CVDs have a significant influence on our patients, being associated with a greater possibility of damage and comorbidities.

Abstract. Technological development for Gymnotus sp. farming is relevant because this species has a socio- economic impact in South American regions where sport fishing is an important activity. Although Gymnotus sp. breeds in captivity, fry survival in ponds can be unacceptable for culture systems. The objective of this work was to test the response to hormonal induction of Gymnotus sp. with carp pituitary extract (CPE) and gonadotrophin-releasing hormone (GnRH) in relation to different male and female reproductive parameters. CPE treatment specimens were stripped 12 and 20 hours after the triggering dosage, and GnRH treatment specimens were stripped 10 and 12 hours after hormonal application. We could obtain positive results using CPE with a short capture-induction interval (C-II) with broodstock in mature stages of gonadal development. Percentage of oocytes with peripheral germinal vesicle (%OPGV) and oocyte diameter showed significant differences between groups treated with CPE. Oocytes could be successfully extracted from two females treated with CPE and stripped 12 hours after the last dosage. Semen was only extracted from males treated with CPE. GnRH stimulation did not give positive results because gametes could not be extracted with different doses and C-II used. This work is the first description of semen quality parameters in Gymnotus sp. Future works should focus on combining hormonal induction strategies with CPE and the management of environmental variables.

Resumen El desarrollo tecnológico para el cultivo de Gymnotus sp. es relevante porque este género tiene un impacto socioeconómico en regiones sudamericanas donde la pesca deportiva es una actividad importante. Aunque Gymnotus sp. se reproduce en cautiverio, la supervivencia de los alevines en los estanques puede ser insuficiente para un sistema de cultivo. El objetivo de este trabajo fue evaluar la respuesta de diferentes parámetros reproductivos a la inducción hormonal en Gymnotus sp. con extracto bruto de hipófisis de carpa (EBH) y hormona liberadora de gonadotrofinas (GnRH). Las muestras de gametos del tratamiento con EBH se extrajeron 12 y 20 horas después de la dosis desencadenante, las muestras del tratamiento con GnRH se extrajeron 10 y 12 horas después de la aplicación hormonal. El porcentaje de ovocitos con vesícula germinal periférica (%OVGP) y el diámetro de los ovocitos mostraron diferencias significativas entre grupos tratados con EBH con un intervalo captura-inducción (IC-I) de corta duración, con reproductores en etapas avanzadas de desarrollo gonadal. Se pudieron extraer ovocitos con éxito a dos hembras inducidas con EBH, 12 horas después de la dosis desencadenante y, además, se extrajo semen sólo de los machos inducidos con EBH. La estimulación con GnRH no dio resultados positivos en las diferentes dosis e IC-I utilizados, dado que no se pudieron extraer gametos. Este trabajo es la primera descripción de los parámetros de calidad del semen en Gymnotus sp. Futuras líneas de trabajo deberán centrarse en el manejo de variables ambientales para establecer una estrategia de reproducción que se pueda utilizar a nivel productivo.

Resumen: En | Texto: En | PDF: En

Abstract Objective: To determine whether peripheral blood parameters have any predictive value for all-frequency Sudden Sensorineural Hearing Loss (SSNHL). Methods: We chose 78 individuals with all-frequency SSNHL who had been admitted to our department. They were divided into two groups: the effective group and the ineffective group. In patients with all-frequency SSNHL, the prognostic variables, including peripheral blood tests and clinical traits, were examined by a logistic regression analysis. In addition, the predictive value was carried out. Results: The effective rate of all-frequency SSNHL was 61.5%. Pre-treatment hearing level and the proportion of patients with diabetes were both significantly lower in the effective group than in the ineffective group (p = 0.024 and 0.000, respectively). The levels of fibrinogen and C-reactive protein were also significantly different between the two groups (p = 0.001 and 0.025, respectively). Pre-treatment hearing level and fibrinogen level both significantly impacted the prognosis of all-frequency SSNHL (p = 0.032 and 0.002, respectively), according to a logistic regression analysis. Furthermore, the prognosis was significantly predicted by both fibrinogen level and pre-treatment hearing level (p = 0.001 and 0.0002, respectively). The receiver operating characteristic curve showed that the fibrinogen level had a sensitivity of 85.4% and a specificity of 60.0% for predicting the prognosis of all-frequency SSNHL. Conclusion: For the prognosis of all-frequency SSNHL, the fibrinogen level can be regarded as a useful predictor. The level of C-reactive protein, however, does not have a significant prognostic effect on predicting all-frequency SSNHL. Therefore, more attention should be devoted to the level of fibrinogen in the acute period of all-frequency SSNHL. Level of Evidence: 4.

Resumen Objetivo: La enfermedad vascular periférica (EVP) afecta generalmente múltiples segmentos de los miembros. Existe información contradictoria con respecto al pronóstico de pacientes con enfermedad aortoilíaca, sin embargo, la diabetes y la enfermedad critica de miembros inferiores habitualmente afecta el territorio infrapatelar. Nuestro objetivo es determinar el impacto de la afectación infrapatelar en eventos cardiovasculares. Métodos: Estudio retrospectivo, observacional en un hospital universitario de Argentina. Se revisó la historia clínica electrónica de pacientes con EVP con requerimiento de revascularización. Se generó un modelo de regresión multivariado incluyendo variables clínicamente relevantes. El punto final primario fue un combinado de hospitalización por isquemia crítica y amputaciones mayores entre pacientes con afectación infrapatelar y suprapatelar. Amputaciones menores, muerte por todas las causas, infarto agudo de miocardio (IAM), accidente cerebrovascular (ACV) y un combinado de eventos cardiovasculares (MACE) fueron los puntos secundarios. Resultados: Se reclutó un total de 309 pacientes desde enero de 2014 hasta julio de 2020. 151 pacientes presentaron enfermedad suprapatelar y 158 infrapatelar. El punto final primario ocurrió en 35 pacientes (22.2%) en el grupo infrapatelar y en 18 pacientes (11.9%) en suprapatelares (HR 2.16; intervalo de confianza 95% [1.22-3.82]; p = 0.008). Ambos componentes ocurrieron con mayor frecuencia en pacientes con afectación infrapatelar. Los eventos de amputación menor fueron mas prevalentes en pacientes con afectación infrapatelar (HR 5.09; IC95% [1.47-17.6]; p = 0.010) La mortalidad por todas las causas, IAM, ACV y MACE no fueron diferentes entre los grupos (p > 0.05). Conclusión: La enfermedad infrapatelar fue un factor independiente para mayor riesgo de hospitalización por isquemia critica, amputación mayor y menor comparado con pacientes con afectación suprapatelar en EVP sintomática revascularizada.

Abstract Background: Peripheral artery disease (PAD) frequently affects multiple segments of the limbs. Contradictory data have reported worse prognosis in aortoiliac lesions, nevertheless, diabetes and chronic limb ischemia frequently affects the infrapatellar territory. Our aim was to assess the impact of infrapatellar disease in cardiovascular outcomes. Methods: We performed a retrospective, observational cohort study at a university hospital in Argentina. Electronic health records were retrospectively reviewed including symptomatic PAD patients requiring revascularization. A multivariable regression model was performed to account for confounders. The primary endpoint was a composite of hospitalizations due to chronic limb threatening ischemia (CLTI) and major amputation events between infrapatellar and suprapatellar patients. Minor amputation events, all-cause death, myocardial infarction (MI), stroke, and major cardiovascular events (MACE) were secondary endpoints. Results: From January 2014 through July 2020, a total of 309 patients were included in the analysis. 151 patients had suprapatellar disease, and 158 had infrapatellar disease. The primary composite endpoint occurred in 35 patients (22.2%) in the infrapatellar patients and 18 patients (11.9%) in the suprapatellar patients (HR = 2.16; 95% confidence interval [CI] = [1.22-3.82]; p = 0.008). Both components of the primary outcomes occurred more frequently in infrapatellar patients. Minor amputation events were more prevalent in infrapatellar patients (HR = 5.09; 95% CI = [1.47-17.6]; p = 0.010). Death, MI, stroke, and MACE events were not different among groups (all p > 0.05). Conclusion: Infrapatellar disease was an independent factor for increased hospitalization of CLTI, major and minor amputations events, compared to suprapatellar disease in symptomatic revascularized PAD patients.

ABSTRACT Introduction: Pulse wave velocity is used to diagnose central arterial stiffness (CAS) and quantify healthy vascular aging (HVA). Objective: To evaluate the CAS and HVA in elderly patients with systemic blood pressure levels classified as optimal/normal. Methods: A total of 102 patients without comorbidities and with systolic pressure (SP) < 120 mmHg and diastolic pressure (DP) < 80 mmHg were selected from the EVOPIU database (Pulse Wave Velocity of Elderly Individuals in an Urban area of Brazil). The carotid-femoral pulse wave velocity (c-fPWV) and the central and peripheral pressures were evaluated in all patients. The patients were divided into four groups: G1: (n = 19, with c-fPWV < 7.6 m/s, without medication), G2 (n = 26, c-fPWV ≥ 7.6 m/s; without medication), G3 (n = 25, c-fPWV < 7.6 m/s with antihypertensive medication), and G4 (n = 32, c-fPWV ≥ 7.6 m/s with antihypertensive medication). Results: In our sample, 56.7% of patients had c-fPWV ≥ 7.6 m/s. The central systolic pressure in G1 [99 (10) mmHg] was lower than that found in the other three groups [vs. 112 (14) mmHg, 111 (15), 112 (20) mmHg; P < 0.05)]. Conclusion: Older people with optimal arterial blood pressure do not necessarily have HVA and could have c-fPWV values close to the limits established for CAS diagnosis.

RESUMO Introdução: A velocidade da onda de pulso é usada para diagnosticar a rigidez arterial central (RAC) e quantificar o envelhecimento vascular saudável (EVS). Objetivo: Avaliar a RAC e o EVS em pacientes idosos com níveis pressóricos sistêmicos classificados como ideais/normais. Métodos: Um total de 102 pacientes sem comorbidades e com pressão sistólica (PS) < 120 mmHg e pressão diastólica (PD) < 80 mmHg foram selecionados do banco de dados EVOPIU (Estudo da Velocidade de Onda de Pulso em Idosos em área Urbana no Brasil). Foram avaliadas a velocidade da onda de pulso carotídeo-femoral (VOPcf) e as pressões central e periférica em todos os pacientes. Os pacientes foram divididos em quatro grupos: G1: (n = 19; com VOPcf < 7,6 m/s; sem medicação), G2 (n = 26; VOPcf ≥ 7,6 m/s; sem medicação), G3 (n = 25; VOPcf < 7,6 m/s com medicação anti-hipertensiva), e G4 (n = 32; VOPcf ≥ 7,6 m/s com medicação anti-hipertensiva). Resultados: Em nossa amostra, 56,7% dos pacientes apresentaram VOPcf ≥ 7,6 m/s. A pressão sistólica central no G1 [99 (10) mmHg] foi inferior à encontrada nos outros três grupos [vs. 112 (14) mmHg, 111 (15), 112 (20) mmHg; P < 0,05)]. Conclusão: Pessoas idosas com pressão arterial ideal não necessariamente têm EVS e podem apresentar valores de VOPcf próximos aos limites estabelecidos para o diagnóstico de RAC.

Resumen: En | Texto: En | PDF: En

ABSTRACT Introduction: Chronic graft-versus-host disease (cGvHD) not only remains the main cause of late mortality after allogeneic hematopoietic cell transplant, but also has the capacity of causing severe organ impairment in those who survive. The Notch, a highly conserved ligand-receptor pathway, is involved in many immunological processes, including inflammatory and regulatory responses. Recently, mouse models have shown that the blockage of canonical Notch signaling prevents GvHD. Objective and Method: Due to the lack of data on the Notch pathway in human chronic GvHD, we sought to study the expression of NOTCH components in primary samples of patients who received allo-HCT and presented active cGvHD or a long-term clinical tolerance to cGvHD. Results: Our results showed a significantly lower expression of NOTCH components in both groups that received allo-HCT, independently of their cGvHD status, when compared to healthy controls. Conclusion: Moreover, there were no differences in gene expression levels between the active cGvHD and clinically tolerant groups. To our knowledge, this is one of the first studies performed in human primary samples and our data indicate that much remains to be learned regarding NOTCH signaling as a new regulator of GvHD.
