RESUMO

Na esteira das lógicas da economia psíquica e da economia política desenvolvidas por Freud e Lacan, tomamos como cerne um tipo de defesa que aparece em muitos casos da clínica contemporânea - o desmentido da privação - para colocar em evidência sua relação com o discurso capitalista pensado por Lacan. O desmentido da privação é um modo de defesa subjetivo que aparece como um índice do fracasso do pai privador na passagem do segundo para o terceiro tempo do complexo de Édipo. Trata-se de uma forma de se defender da castração buscando satisfação pulsional sem mediação simbólica ­ busca essa que é fracassada e extrapola o princípio de prazer. Conclui-se que esse desmentido contemporâneo é um sintoma do próprio discurso capitalista. Se a for aclusão da castração no discurso capitalista é uma promessa igualmente fracassada, o desmentido da privação aparece na subjetividade tentando solucionar esse fracasso. Ele é um sinal de que o discurso capitalista não cumpre sua promessa - e isso por sua própria engrenagem lógica.


Dans le sillage des logiques d'économie psychique et d'économie politique développées par Freud et Lacan, nous nous concentrons sur un type de défense qui apparaît dans de nombreux cas de pratique clinique contemporaine - le déni de la privation - pour mettre en évidence sa relation avec le discours capitaliste d' accord avec ce qui fut pensé par Lacan. Le déni de la privation est une défense subjective qui apparaît comme un indice de l'échec du père qui prive dans le passage du deuxième au troisième stade du complexe d'Œdipe. C'est une manière de se défendre de la castration en recherchant une satisfaction pulsionnelle sans médiation symbolique ­ une recherche qui échoue et dépasse le principe du plaisir. Nous concluons que ce déni contemporain est un symptôme du discours capitaliste lui-même. Si la for clusion de la castration dans le discours capitaliste est une promesse également ratée, le déni de la privation apparaît dans la subjectivité qui tente de résoudre cet échec. C'est le signe que le discours capitalistene tient pas ses promesses - et cela par sa propre logique.


Following the logics of psychic economy and political economy developed by Freud and Lacan, we target a type of defense that appears in many cases of contemporary clinical practice - the denial of deprivation - to highlight its relationship with the capitalist discourse as thought by Lacan. The denial of deprivation is a subjective defense that appears as an index of the failure of the depriving father in the transition from the second to the third stage of the Oedipus complex. It is a way of defending oneself from castration by seeking instinctual satisfaction without symbolic mediation ­ a search that fails and goes beyond the pleasure principle. The conclusion is that this contemporary denial is a symptom of capitalist discourse itself. If the foreclosure of castration in capitalist discourse is an equally failed promise, the denial of deprivation appears in subjectivity trying to resolve this failure. It is a sign that capitalist discourse does not fulfill its promise - and this by its own logical perspective.

RESUMO

O objetivo do estudo foi avaliar a qualidade do sono e sonolência diurna de um grupo de idosos, verificar se há associação com prática de atividade física, presença de doença crônica, e Índice de Massa Corporal (IMC) e se há correlação com IMC, idade e qualidade de vida. Trata-se de um estudo transversal e descritivo. Para avaliação da qualidade do sono utilizou-se o Pittsburgh Sleep Quality Index (PSQI), para avaliação da sonolência diurna a Escala de Sonolência de Epworth (ESE) e para avaliação da qualidade de vida o WHOQOL-BREF. Foram avaliados 47 idosos com mediana (intervalo interquartil 25-75%) de 66 (62-70) anos de idade e IMC de 28,58 (26,21-30,44). 74,5% apresentaram sono ruim, 61,7% apresentaram Sonolência Diurna Normal e 97,8% classificados com boa qualidade de vida, com destaque para os domínios relações sociais (80%) e autoavaliação da qualidade de vida (80%). Apenas apresentou associação estatisticamente significativa a presença de qualidade de sono ruim com a prática de atividade física. Não houve associação entre presença de qualidade de sono ruim ou sonolência com IMC e presença de doença crônica. Houve uma correlação fraca, negativa e estatisticamente significativa apenas entre qualidade do sono com qualidade de vida (ρ=-0,466) e idade (ρ=-0,297). Conclui-se que os idosos apresentaram qualidade do sono ruim, sonolência diurna normal e qualidade de vida geral boa.


The objective of the study was to evaluate the quality of sleep and daytime sleepiness of a group of elderly people, checking whether there is an association with physical activity, presence of chronic disease, and Body Mass Index (BMI) and whether there is a correlation with BMI, age and quality of life. This is a cross-sectional and descriptive study. To assess sleep quality, the Pittsburgh Sleep Quality Index (PSQI) was used, the Epworth Sleepiness Scale (ESE) was used to assess daytime sleepiness, and the WHOQOL-BREF was used to assess quality of life. 47 elderly people were evaluated with a median (interquartile range 25-75%) of 66 (62-70) years of age and BMI of 28.58 (26.21-30.44). 74.5% had poor sleep, 61.7% had Normal Daytime Sleepiness and 97.8% classified as having a good quality of life, with emphasis on the domains of social relationships (80%) and self-assessment of quality of life (80%). There was only a statistically significant association between the presence of poor sleep quality and the practice of physical activity. There was no association between the presence of poor sleep quality or sleepiness with BMI and the presence of chronic disease. There was a weak, negative and statistically significant correlation only between sleep quality and quality of life (ρ=-0.466) and age (ρ=- 0.297). It is concluded that the elderly had poor sleep quality, normal daytime sleepiness and good general quality of life.

RESUMO

ABSTRACT Objective: To investigate the association between sleep duration, nocturnal awakenings, and sleep latency with body mass index (BMI) at six and 12 months of age. Methods: 179 children from a birth cohort were enrolled. At six and 12 months of age, anthropometric data were obtained using standardized techniques and infants' mothers answered the Brief Infant Sleep Questionnaire for sleep data. The association of BMI with the independent variables (sleep duration, latency, and nocturnal awakenings) was assessed by linear regression models. Analyses were adjusted for potential confounders and a p-value<0.05 was adopted to define statistical significance. Results: For each additional hour of sleep duration, BMI was reduced by 0.15 kg/m² (95% confidence interval [CI] -0.28; -0.01; p=0.03) and each additional minute of sleep latency increased BMI by 0.01 kg/m² (95%CI -0.00; 0.03; p=0.02). These associations were independent of gestational age, child sex, birth weight, duration of exclusive breastfeeding, smoking during pregnancy, and mother's BMI, education, and marital status. Nocturnal awakenings showed no association with the outcome. Conclusions: Our findings suggest that sleep duration and sleep latency time are associated with BMI in the first year of life. Insights into the influence of sleep early in life on weight status may be helpful to complement future nutritional recommendations and prevent and treat obesity.


RESUMO Objetivo: Investigar a associação entre duração do sono, despertares noturnos e latência do sono com o índice de massa corporal (IMC) aos seis e 12 meses de idade. Métodos: foram incluídas 179 crianças de uma coorte de nascimentos. Aos seis e 12 meses de idade, dados antropométricos foram obtidos por meio de técnicas padronizadas e as mães dos lactentes responderam ao Brief Infant Sleep Questionnaire para dados do sono. A associação do IMC com as variáveis independentes (duração do sono, latência e despertares noturnos) foi avaliada por modelos de regressão linear. As análises foram ajustadas para potenciais fatores de confusão e o p-valor<0,05 foi adotado para definir a significância estatística. Resultados: Para cada hora adicional de duração do sono, o IMC foi reduzido em 0,15 kg/m² (intervalo de confiança [IC]95% -0,28; -0,01; p=0,03) e cada minuto adicional no tempo de latência resultou em aumento de 0,01 kg/m² (IC95% -0,00; 0,03; p=0,02) no IMC. Essas associações foram independentes da idade gestacional, sexo da criança, peso ao nascer, duração do aleitamento materno exclusivo, tabagismo durante a gravidez e IMC, escolaridade e estado civil da mãe. Os despertares noturnos não apresentaram associação com o desfecho. Conclusões: Nossos achados sugerem que a duração e a latência do sono estão associadas ao IMC no primeiro ano de vida. Informações sobre a influência do sono no início da vida sobre o status do peso podem ser úteis para complementar futuras recomendações nutricionais e prevenir e tratar a obesidade.

RESUMO

ABSTRACT Objective This survey aims atreviewing the journalistic narratives of the newspaper Folha de São Paulo (digital edition) about hunger in Brazil during the 2020 pandemic period. It is known that journalism plays an important role in keeping the public informed and in helping to contribute to the shaping of society's opinion. Despite hunger being a structural phenomenon in this country, little is published in the mainstream media discussing the magnitude of the problem and the articulation of measures taken in the three government spheres (federal, state and municipal), to ensure access to food to the most vulnerable populations. Method News excerpts addressing hunger as the main topic were selected from Folha de São Paulo daily newspaper and were highlighted based on reading keys (n=11, published between March and December 2020). Results In all the selected articles, the newspaper addressed the cause of hunger from the perspective of the pandemic (passing event and manifestation). Issues linked to the economic and social crisis experienced in the country were not emphasized. This form of covering hunger in news articles can enhance the idea that the poor are the result of the currently spreading fatality. Conclusion Finally, from these first results we could infer that the newspaper, when addressing hunger in Brazil in the first months of the COVID-19 pandemic, sought to construct a biased reality that hunger was derived from the health crisis, at the same time that it presents the hungry people narratives as a discursive strategy to sensitize the reader to Folha de São Paulo intentions.


RESUMO Objetivo A nota tem como objetivo examinar as narrativas jornalísticas do jornal Folha de São Paulo (digital) sobre a fome no Brasil, no período pandêmico de 2020, uma vez que se compreende que as narrativas jornalísticas têm um papel importante na formação de opinião da sociedade. Apesar da fome ser um fenômeno estrutural no país, pouco se vê nos grandes meios de comunicação o debate sobre a magnitude dos problemas e articulação de medidas governamentais nas três esferas de gestão (federal, estadual e municipal), que possam assegurar o acesso à alimentação adequada e saudável dos mais vulneráveis. Método Foram selecionadas notícias na Folha de São Paulo que tratavam da fome como pauta principal, sendo analisadas com base em chaves de leitura (n=11, divulgadas entre março e dezembro de 2020). Resultados Em todas as matérias selecionadas o jornal abordou a causa da fome a partir da perspectiva da pandemia (acontecimento e manifestação passageira). As questões vinculadas à crise econômica e social vivenciada no país não foram enfatizadas. A forma de acionar os famintos nas matérias pode reforçar a ideia de que os pobres são fruto da fatalidade que se propaga. Conclusão Por fim, os resultados iniciais permitem inferir que o jornal ao editar a fome no Brasil, no primeiro ano da pandemia de COVID-19, procurou construir uma realidade enviesada de que a fome é derivada de uma crise sanitária ao mesmo tempo que apresenta as narrativas dos famintos como estratégia discursiva para sensibilizar o leitor em relação às suas intenções.

RESUMO

OBJECTIVE To determine the optimal therapeutic plan for metastatic hormone-sensitive prostate cancer (mHSPC), and to provide reference for clinical decision-making. METHODS Retrieved from Medline, Embase, BIOSIS preview, the Cochrane Library and ClinicalTrials. gov systematically, randomized controlled trials about mHSPC therapy, with overall survival (OS) and radiographic progression-free survival (rPFS) as efficacy outcomes and the incidence of serious adverse events (SAEs) as safety outcome, were collected during the inception-Mar. 2022. Two researchers independently screened the literature, extracted data, and evaluated the risk of bias for the included study before conducting a Bayesian network meta-analysis. RESULTS Eight studies with 9 437 patients were finally included. The effectiveness and safety of 7 therapy plans were compared [abiraterone acetate, apalutamide, darolutamide+docetaxel, docetaxel, enzalutamide, standard non-steroidal antiandrogen (SNA) in addition to ADT, and ADT alone]. In terms of efficacy index, the most beneficial regimen (except for ADT+SNA) for OS was ADT+darolutamide+docetaxel (HR=0.54, 95%CI of 0.44-0.66), followed by ADT+abiraterone acetate (HR=0.64,95%CI of 0.57- 0.71), apalutamide (HR=0.65, 95%CI of 0.53-0.79), enzalutamide (HR=0.66, 95%CI of 0.53-0.82); the least beneficial regimen for OS was ADT+docetaxel (HR=0.79, 95%CI of 0.71-0.88). The most beneficial regimen (except for ADT+SNA) for rPFS was ADT+enzalutamide (HR=0.39, 95%CI of 0.30-0.50), followed by ADT+apalutamide (HR=0.48, 95%CI of 0.39- 0.60), abiraterone acetate (HR=0.57, 95%CI of 0.51-0.64), docetaxel (HR=0.62, 95%CI of 0.56-0.69). The results of the tumor- loading subgroup analysis were the same. In terms of safety, ADT+darolutamide+docetaxel (OR=25.86, 95%CI of 14.08-51.33), and ADT+docetaxel (OR=23.35, 95%CI of 13.26-44.81) were associated with markedly increased SAEs; the incidence of SAEs caused by ADT+abiraterone acetate (OR=1.42,95%CI of 1.10-1.82) was slightly increased, and those of other therapy plans had no significant difference. CONCLUSIONS Compared with ADT alone, ADT+ darolutamide+docetaxel may provide the most significant OS benefit, but the incidence of SAEs is increased greatly; compared with ADT+docetaxel, ADT+abiraterone acetate, apalutamide or enzalutamide provide more OS benefits. ADT+enzalutamide provide optimal rPFS benefits with no increased SAEs.

RESUMO

ObjectiveTo investigate the effect and mechanism of salvianolic acid B combined with puerarin in protecting the SH-SY5Y cells from the damage by oxygen-glucose deprivation/reoxygenation (OGD/R) based on pyroptosis. MethodSH-SY5Y cells were used to establish the model of OGD/R, and cells were classified into the control, OGD/R, 10 μmol·L-1 salvianolic acid B, 100 μmol·L-1 puerarin, 10 μmol·L-1 salvianolic acid B + 100 μmol·L-1 puerarin, and 10 μmol·L-1 NOD-like receptor protein 3 (NLRP3) inhibitor MCC950 groups. Except the control group, other groups were rapidly reoxygenated for 12 h after 6 h OGD for modeling. The cell survival rate was determined by the methyl thiazolyl tetrazolium (MTT) assay. An optical microscope was used to observe the cell morphology. A spectrophotometer was used to determine the content of lactic dehydrogenase (LDH) in culture supernatant. Cell damage was measured by Hoechst/PI staining. The mRNA levels of NLRP3, cysteinyl aspartate specific proteinase-1 (Caspase-1), gasdermin D (GSDMD), apoptosis-associated speck-like protein (ASC), and interleukin-1β (IL-1β) were determined by real-time fluorescence quantitative polymerase chain reaction (Real-time PCR). The protein activation of Caspase-1 and NLRP3 was detected by immunofluorescence. Western blot was employed to determine the protein levels of IL-1β, ASC, NLRP3, Caspase-1, and cleaved Caspase-1. ResultCompared with the control group, the OGD/R group showed decreased cell survival rate (P<0.01), damaged cell morphology, increased leakage rate of LDH (P<0.01), up-regulated mRNA levels of NLRP3, Caspase-1, GSDMD, ASC, and IL-1β (P<0.01), and up-regulated protein levels of IL-1β, ASC, NLRP3, Caspase-1, and cleaved Caspase-1 (P<0.01). Compared with the OGD/R group, salvianolic acid B, puerarin, and salvianolic acid B combined with puerarin improved cell survival rate (P<0.01), and the combined treatment group outperformed salvianolic acid B and puerarin used alone (P<0.01). Salvianolic acid B combined with puerarin and MCC950 both improved cell morphology, reduced the leakage of LDH (P<0.01), alleviated cell damage, and down-regulated the mRNA levels of NLRP3, Caspase-1, GSDMD, ASC, and IL-1β (P<0.05, P<0.01) and also the protein levels of IL-1β, ASC, NLRP3, Caspase-1, and cleaved Caspase-1 (P<0.05, P<0.01). ConclusionThe results indicated that salvianolic acid B combined with puerarin can alleviate the OGD/R-induced damage of SH-SY5Y cells by inhibiting pyroptosis.

RESUMO

Background: Androgen deprivation therapy (ADT) is indispensable part of treatment for metastatic prostate cancer (MPC) patients. There is documented association between ADT and adverse cardiovascular (CV) events, with variability between the different modes. However, there is dearth of evidence on the background CV risk factors of these group of patients at diagnosis. Aims and Objectives: We envisaged this retrospective observational study in the department of oncology to document the background CV risk factors of MPC patients at diagnosis, to help us better select the available ADTs based on their CV risks. Materials and Methods: Over a period of 2 years, all patients registered for treatment with a diagnosis of MPC, indicated for ADT, and available detailed history and background cardiological evaluation at presentation, were included in the study. As indirect indicators of CV risks, history of smoking, presence and treatment of dyslipidemia, and type 2 diabetes mellitus (T2DM), were documented. As direct indicators of CV risks, presence and treatment of hypertension, ischemic heart disease (IHD), congestive cardiac failure (CCF), ECG, and echocardiography changes suggesting cardiac morbidity were documented and the data were analyzed using descriptive statistical methods. Results: Indirect indicators: dyslipidemia, habit of smoking, and T2DM were found in 74%, 29.3%, and 13.3% patients, respectively. Direct indicators: Presence of hypertension, IHD, CCF, abnormalities in ECG, and echocardiography were found in 38.7%, 10.6%, 4%, 28%, and 34.6% patients, respectively. ST-T changes on ECG, low EF, and IHD on echocardiography were seen in 28.5%, 23%, and 26.9%, respectively. Conclusions: MPC patients have a substantial pre-existing CV risk at diagnosis. Our findings warrant a meticulous screening of all MPC patients for CV risk factors, to help in judicious selection of their ADT.

RESUMO

Introduction: The COVID?19 pandemic took the entire world unawares and people were forced to stay indoors overnight. Due to this a drastic change ensued in lifestyle with many succumbing to various kinds of stresses and psychological problems. This study aims to study the changing sleep patterns and level of anxiety among the working population due to the COVID?19 Pandemic lockdown. Methodology: An online survey was conducted using a cloud?based website. The sleep patterns both prior to and during the lockdown period of the pandemic were assessed using a self?administered questionnaire. The level of anxiety during both these periods (before and during lockdown) amongst the working population was also assessed using the Generalized Anxiety Disorder Scores (GADS). Results: A total of 224 individuals participated in the study of which 52.7% were males and 47.3% were females. On analysis, the lifestyle and sleep deprivation scores showed that before the lockdown only 2.7% reported a low score out of total participants. However, this number was raised to 13.4% during the lockdown. The percentage of people reporting deteriorated sleep quality gradually increased with females reporting moderate to severe category of Generalized Anxiety Disorder scores as compared to Males. Conclusion: The study suggests that there has been a significant change in the sleep quality of the study participants due to Covid enforced lockdown which if unnoticed might lead to significant health problems. The effective use of programs like yoga, meditation, and deep breathing exercises, if followed timely could reduce psychological distress to some extent.

RESUMO

Abstract Objective: The aim of this study was to investigate the association between iron deficiency anemia and sleep duration in the first year of life. Methods: A total of 123 infants were investigated, with sleep being evaluated at 3, 6, and 12 months of age and anemia at birth and 6 months. The cutoff points for anemia and short sleep duration were hemoglobin <11 g/dL (at birth and/or 6 months) and <10 h (at 3, 6, and 12 months), respectively. The comparison of the average sleep time between infants with and without anemia was performed using the Student's t-test, and logistic regression models were also used to verify differences in the sleep duration (short/not short) between the groups. Linear regression analyses were conducted to determine the association between sleep duration and hemoglobin values. The analyses were adjusted for potential confounders. Results: Children with anemia were more likely to be short sleepers [odds ratio (95% confidence interval (CI)): 4.02 (1.02-15.76); p≤0.05], and for each unit increase in hemoglobin values, the sleep duration increased by 16.2 min [β (95%CI): 0.27 (0.00-0.55); p≤0.05), regardless of family income, maternal schooling, gender, and body mass index at birth. Conclusions: Our results suggest that iron deficiency anemia is associated with short sleep duration in the first year of life and indicate the need for longitudinal investigations, with longer follow-up, to verify the impact of anemia on sleep duration at subsequent ages.


RESUMO Objetivo: Investigar a associação entre a anemia por deficiência de ferro e a duração do sono no primeiro ano de vida. Métodos: Foram avaliadas 123 crianças, sendo o sono investigado aos três, seis e 12 meses de idade e a anemia ao nascimento e aos seis meses. Utilizaram-se como pontos de corte para anemia e curta duração de sono, respectivamente, hemoglobina<11 g/dL (nascimento e/ou seis meses) e tempo total <10 h (3, 6 e/ou 12 meses). A comparação do tempo médio de sono entre as crianças com e sem anemia foi realizada pelo teste t de Student e modelos de regressão logística foram usados para verificar diferenças na duração do sono (curta/não curta) entre os grupos. Análises de regressão linear foram conduzidas para determinar a associação entre a duração do sono e valores de hemoglobina. As análises foram ajustadas para potenciais confundidores. Resultados: As crianças com anemia tiveram maior chance de apresentar curta duração do sono [odds ratio — OR (intervalo de confiança — IC95%): 4,02 (1,02-15,76); p≤0,05]. Para cada unidade de aumento nos valores da hemoglobina, o tempo de sono aumentou em 16,2 min [β (IC95%): 0,27 (0,00-0,55); p≤0,05), independentemente de renda familiar, escolaridade materna, sexo e índice de massa corporal ao nascimento. Conclusões: Nossos resultados sugerem que a anemia ferropriva está associada à curta duração do sono no primeiro ano de vida e indicam a necessidade de investigações longitudinais, com maior tempo de seguimento, para verificar o impacto da anemia na duração do sono em idades subsequentes.

RESUMO

RESUMO Em seu capítulo sobre medidas socioeducativas, o Estatuto da Criança e do Adolescente (ECA) propõe a aplicação de medidas a adolescentes autores de atos infracionais, cujo caráter deve ser educativo e não punitivo. O objetivo desse trabalho foi mapear as dissertações indexadas na base Capes sobre a privação de liberdade de adolescentes defendidas entre 2007 e 2016 que respondiam ao problema de pesquisa: 'Quais as contribuições da privação de liberdade como medida socioeducativa para o desenvolvimento de jovens no Brasil?', tendo sido identificadas 1.133 dissertações. Para atender ao objetivo proposto, realizou-se uma pesquisa documental, na qual foram selecionadas 174 dissertações e foi possível perceber vários problemas na execução da medida socioeducativa e que estão em desacordo com as prescrições do Sinase. Em muitos casos, a concepção punitiva se sobrepõe ao aspecto pedagógico, levando a uma aproximação entre o sistema socioeducativo e o sistema prisional. Destaca-se a necessidade de os órgãos responsáveis fiscalizarem os centros socioeducativos para a garantia do cumprimento das normativas.


RESUMEN En su capítulo sobre medidas socioeducativas, el Estatuto de la Infancia y de la Adolescencia (ECA) propone la aplicación de medidas a los adolescentes que han cometido infracciones cuyo carácter debe ser educativo y no punitivo. El objetivo de este trabajo fue mapear las disertaciones indexadas en la base de datos CAPES sobre la privación de libertad de adolescentes defendidas entre 2007 y 2016 que respondió al problema de investigación: '¿Cuáles son las contribuciones de la privación de libertad como una medida socioeducativa para el desarrollo de los jóvenes en Brasil?', habiendo sido identificados 1133 disertaciones. Para cumplir con el objetivo propuesto, se realizó una investigación documental, en la que se seleccionaron 174 disertaciones y se pudo percibir varios problemas en la ejecución de la medida socioeducativa y que están en desacuerdo con las prescripciones del SINASE. En muchos casos, la concepción punitiva se superpone al aspecto pedagógico, lo que lleva a una aproximación entre el sistema socioeducativo y el sistema penitenciario. Se destaca la necesidad de que los organismos responsables inspeccionen los centros socioeducativos para garantizar el cumplimiento de la normativa.


ABSTRACT In its chapter on socio-educational measures, the Statute of Children and Adolescents (ECA) proposes the application of measures to adolescents who have committed infractions whose character must be educational and not punitive. The objective of this work was to map the dissertations indexed in the CAPES database on the deprivation of liberty of adolescents defended between 2007 and 2016 that answered the research problem: 'What are the contributions of the deprivation of liberty as a socio-educational measure for the development of young people in Brazil?', having identified 1133 dissertations defended in this period. In order to meet the proposed objective, a documentary research was carried out, in which 174 dissertations were selected and it was possible to perceive several problems in the execution of the socio-educational measure and which are in disagreement with the SINASE prescriptions. In many cases, the punitive conception overlaps the pedagogical aspect, leading to an approximation between the socio-educational system and the prison system. The need for the responsible bodies to inspect the socio-educational centers is highlighted in order to guarantee compliance with the regulations.

RESUMO

ABSTRACT BACKGROUND: The coronavirus disease (COVID-19) pandemic has adversely affected the health of the global population, with sleep quality being one of the affected parameters. OBJECTIVES: To evaluate sleep quality and its associated factors in adults during the COVID-19 pandemic in Brazil. DESIGN AND SETTING: A population-based cross-sectional serological survey of 1,762 adults in the Iron Quadrangle region of Brazil. METHODS: The Pittsburgh Sleep Quality Index was used to assess sleep quality. Sociodemographic variables, health conditions, health-related behaviors, anxiety, vitamin D levels, weight gain/loss, and pandemic characteristics were assessed using a structured questionnaire. Univariate and multivariate analyses using Poisson regression with robust variance were performed to identify factors associated with sleep quality. RESULTS: More than half of the participants reported poor sleep quality (52.5%). Multivariate analysis revealed that the factors associated with poor sleep quality included living alone (prevalence ratio [PR] = 1.34; 95% confidence interval [CI]: 1.04-1.73), anxiety disorder (PR = 1.32; 95% CI: 1.08-1.62), 5.0% weight loss (PR = 1.21; 95% CI: 1.02-1.44), 5.0% weight gain (PR = 1.27; 95% CI: 1.03-1.55), vitamin D deficiency (PR = 1.16; 95% CI: 1.01-1.35), and COVID-19 symptoms (PR = 1.29; 95% CI: 1.10-1.52). CONCLUSIONS: Our study revealed that more than half of the participants experienced poor sleep quality during the COVID-19 pandemic. Factors associated with poor sleep quality included vitamin D deficiency and weight changes related to the pandemic.

RESUMO

Introdução: A privação de sono participa de diversos processos neuropatoló- gicos, inclusive na fisiopatologia da Doença de Alzheimer, demência progressiva e mul- tifatorial com morbimortalidade crescente. Ademais, figura como um importante fator de risco modificável da mesma. Portanto, buscou-se analisar a produção científica relevante ao tema e averiguar essa correlação. Metodologia: Trata-se de uma revisão de literatura com artigos publicados entre os anos de 2017 e 2022 nas bases de dados PubMed e SCO- PUS.

Introduction: Sleep deprivation is involved in various neuropathological processes, including the pathophysiology of Alzheimer's disease, a progressive and multifactorial dementia with increasing morbidity and mortality. Moreover, it is an important modifiable risk factor for Alzheimer's disease. Therefore, we sought to analyze relevant scientific production on the subject and investigate this correlation. Methodology: This is a literature review of articles published between 2017 and 2022 in the databases PubMed and SCOPUS. Results: 13 articles analyzed, corresponding to 87% of the sample, found a correlation between sleep deprivation and some element of the pathophysiology of Alzheimer's disease, especially through the accumulation of extracellular ß-amyloid plaques and their poor clearance by the glymphatic system. Conclusion: Sleep deprivation plays a strong role in neurodegenerative processes, including Alzheimer's disease. Sleep promotion strategies with good duration and quality are necessary and open new perspectives for preventive measures and effective implementation of disease-modifying therapies, requiring studies with larger populations and duration for better understanding of this relationship.

RESUMO

ObjectiveTo explore the mechanism of Huanglian Ejiaotang in intervening in insomnia based on 5-hydroxytryptamine (5-HT) system and gut microbiota. MethodFifty-five SPF-grade SD rats were randomly divided into normal group, model group, low-, medium-, and high-dose Huanglian Ejiaotang groups (1.925, 3.85, and 7.7 g·kg-1), and Estazolam group (0.1 mg·kg-1). Except for those in the normal group, the rats in the other five groups were subjected to sleep deprivation on a narrow platform for 12 hours daily for 21 consecutive days. After 14 days of drug intervention, the sleep, exploratory behavior, and depressive-like behavior of the rats were assessed using the pentobarbital sodium sleep synergistic test, the open field test, and the sugar preference test, respectively. Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of 5-HT, 5-hydroxyindoleacetic acid (5-HIAA), tryptophan hydroxylase (TPH), and monoamine oxidase-A (MAO-A). Real-time polymerase chain reaction (Real-time PCR) was used to measure the mRNA expression of the 5-HT1A receptor (5-HT1AR) and 5-HT2A receptor (5-HT2AR). Differences in gut microbiota among the groups were assessed using 16S rRNA sequencing, and the correlation between the 5-HT system and microbiota was revealed using redundancy analysis. ResultCompared with the normal group, the model group showed a prolonged sleep latency (P<0.05), reduced sleep maintenance (P<0.01), decreased central area activity time in the open field (P<0.01), and reduced sugar preference rate (P<0.05). Moreover, the model group also showed decreased levels of 5-HT, 5-HIAA, TPH, and MAO-A (P<0.01), decreased 5-HIAA/5-HT ratio (P<0.01), downregulated mRNA expression of 5-HT1AR (P<0.01), and upregulated mRNA expression of 5-HT2AR (P<0.05). The proportion of Firmicutes decreased, while that of Bacteroidetes increased, leading to a decreased Firmicutes/Bacteroidetes (F/B) ratio (P<0.05). Compared with the model group, the high-dose Huanglian Ejiaotang group exhibited a shortened sleep latency (P<0.01), and increased sleep maintenance (P<0.01). The low-dose Huanglian Ejiaotang group showed increased central area activity time (P<0.01) and an increased sugar preference rate (P<0.05). The high-dose Huanglian Ejiaotang group exhibited increased levels of 5-HT, 5-HIAA, TPH, and MAO-A (P<0.01), increased 5-HIAA/5-HT ratio (P<0.05), upregulated mRNA expression of 5-HT1AR (P<0.01), and downregulated mRNA expression of 5-HT2AR (P<0.05). The low-dose Huanglian Ejiaotang group displayed an increased proportion of Firmicutes and a decreased proportion of Bacteroidetes, resulting in an increased F/B ratio. At the phylum level, 5-HT, 5-HIAA, and MAO-A were positively correlated with Firmicutes and negatively correlated with Bacteroidetes. At the genus level, 5-HT, 5-HIAA, TPH, and MAO-A were negatively correlated with Prevotella and Lactobacillus and positively correlated with Blautia and Bacteroides. ConclusionHuanglian Ejiaotang can improve sleep deprivation-induced insomnia and depressive-like behavior by regulating the activity of the 5-HT system and the composition of gut microbiota.

RESUMO

Disruption of the structure of regular sleep is a common cause of neurodegenerative diseases such as Alzheimer′s disease and Parkinson′s disease, and its pathogenesis may be related to the deposition of waste products in the central nervous system. The glymphatic pathway, which is essentially a periarterial cerebrospinal fluid inflow pathway and peripheral venous clearance pathway, is functionally dependent on interstitial bulk flow coupling supported by aquaporin-4 on the astrocyte end-foot, also known as the lymphoid glial system. The glymphatic pathway, which removes waste proteins from the brain, is active primarily during sleep, and sleep quality declines with age, while the glymphatic pathway system also deteriorates with age, suggesting a relationship between sleep disturbances and symptom progression in neurodegeneration, and glymphatic system as a link closely links the two. The interaction of sleep, aging, metabolic waste and glymphatic pathway reticulation provides new clues to the pathogenesis of central nervous system degenerative diseases, and the glymphatic pathway may constitute a new target on treatment. The recent research progress on the effects of sleep and sleep disorders on the circulation of the glymphatic system, and proposes the possibility of sleep intervention to slow down the impairment of the lymphoid system function or even restore the function of the lymphoid system and thus improve the disease development process were reviewed in this paper.

RESUMO

Stigmasterol is a plant sterol with anti-apoptotic, anti-oxidative and anti-inflammatory effect through multiple mechanisms. In this study, we further assessed whether it exerts protective effect on human brain microvessel endothelial cells (HBMECs) against ischemia-reperfusion injury and explored the underlying mechanisms. HBMECs were used to establish an in vitro oxygen and glucose deprivation/reperfusion (OGD/R) model, while a middle cerebral artery occlusion (MCAO) model of rats were constructed. The interaction between stigmasterol and EPHA2 was detected by surface plasmon resonance (SPR) and cellular thermal shift assay (CETSA). The results showed that 10 μmol·L-1 stigmasterol significantly protected cell viability, alleviated the loss of tight junction proteins and attenuated the blood-brain barrier (BBB) damage induced by OGD/R in thein vitro model. Subsequent molecular docking showed that stigmasterol might interact with EPHA2 at multiple sites, including T692, a critical gatekeep residue of this receptor. Exogenous ephrin-A1 (an EPHA2 ligand) exacerbated OGD/R-induced EPHA2 phosphorylation at S897, facilitated ZO-1/claudin-5 loss, and promoted BBB leakage in vitro, which were significantly attenuated after stigmasterol treatment. The rat MCAO model confirmed these protective effects in vivo. In summary, these findings suggest that stigmasterol protects HBMECs against ischemia-reperfusion injury by maintaining cell viability, reducing the loss of tight junction proteins, and attenuating the BBB damage. These protective effects are at least meditated by its interaction with EPHA2 and inhibitory effect on EPHA2 phosphorylation.

RESUMO

In order to investigate the effects of asiaticoside (Ass) on H9C2 cardiomyocytes, the present study examined the potential intervention of Ass on the proliferation and phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/Bcl-2 homology domain protein (Beclin-1) signaling pathway in H9C2 cardiomyocytes following oxygen and glucose deprivation/reperfusion (OGD/R) injury. H9C2 cardiomyocytes were selected as the research objects, and the activity of H9C2 was detected by cell counting kit-8 (CCK-8). H9C2 cells were divided into control group, OGD/R group, Ass low concentration group (10 μmol·L-1), Ass high concentration group (80 μmol·L-1) and Ass high concentration + chloroquine group (80 μmol·L-1 + 50 μmol·L-1). The control group was cultured under normal conditions, and the other groups were treated with oxygen and glucose deprivation for 4 h and reperfusion for 2 h. The activity and content of aspartic aminotransferase (AST), lactate dehydrogenase (LDH) and creatine kinase (CK) in the supernatant of H9C2 cardiomyocytes were detected by enzyme-linked immunosorbent assay. Autophagy staining assay kit with monodansylcadaverine (MDC) method to observe cellular autophagy; molecular docking technique to identify the molecular targets of Ass. Immunofluorescence was used to observe the effect of the drug on cell number. The expression levels of PI3K, Akt, selective autophagy adaptor protein (P62) and Beclin-1 were detected by Western blot. Compared with OGD/R group, Ass group had a protective effect from 10-80 μmol·L-1, and the activities and contents of AST, LDH and CK were decreased. The protein expression levels of PI3K, Akt, P62 and Beclin-1 were decreased. Compared with the administration group, the activities and contents of AST, LDH and CK in Ass high-concentration + chloroquine group were significantly decreased, and the protein expression levels of PI3K, Akt, Beclin-1 and P62 were significantly decreased. Immunofluorescence showed that the inhibitor group and each administration group had different degrees of protective effect compared with the model group. Asiaticoside can reduce the injury of H9C2 cardiomyocyte induced by OGD/R, reduce the content of AST, LDH and CK, reduce the expression level of P62 protein, and reduce autophagy, which may be closely related to the inhibition of PI3K/Akt/Beclin-1 signaling pathway activation.

RESUMO

Objective We aimed to investigate whether antagonism of the cannabinoid CB1 receptor (CB1R) could affect novel object recognition (NOR) memory in chronically rapid eye movement sleep-deprived (RSD) rats.Methods The animals were examined for recognition memory following a 7-day chronic partial RSD paradigm using the multiple platform technique. The CB1R antagonist rimonabant (1 or 3 mg/kg, i.p.) was administered either at one hour prior to the sample phase for acquisition, or immediately after the sample phase for consolidation, or at one hour before the test phase for retrieval of NOR memory. For the reconsolidation task, rimonabant was administered immediately after the second sample phase.Results The RSD episode impaired acquisition, consolidation, and retrieval, but it did not affect the reconsolidation of NOR memory. Rimonabant administration did not affect acquisition, consolidation, and reconsolidation; however, it attenuated impairment of the retrieval of NOR memory induced by chronic RSD.Conclusions These findings, along with our previous report, would seem to suggest that RSD may affect different phases of recognition memory based on its duration. Importantly, it seems that the CB1R may, at least in part, be involved in the adverse effects of chronic RSD on the retrieval, but not in the acquisition, consolidation, and reconsolidation, of NOR memory.

RESUMO

OBJECTIVE To study the protective mechanism of Bawei chenxiang powder containing serum on H9c2 cells injured by oxygen-glucose deprivation (OGD). METHODS H9c2 cells were divided into blank group, model group and Bawei chenxiang powder low-dose, medium-dose and high-dose groups (the dose of drug containing serum 2.5, 8, 12 g/kg). H9c2 cells were cultured in vitro to establish OGD model. After intervention with drug-containing serum, survival rate of cell was detected. The cell morphology was observed; the levels of lactate dehydrogenase (LDH), creatine kinase (CK), superoxide dismutase (SOD), catalase (CAT), respiratory chain complexⅠ (ComplexⅠ), glutathione peroxidase (GSH-Px) and malondialdehyde (MDA) were detected. The contents of reactive oxygen species (ROS), mitochondrial membrane potential and apoptosis were also detected. The expressions of oxidative stress-related proteins [Kelch ECH association protein 1 (Keap1), nuclear factor erythroid 2- related factor 2 (Nrf2), heme oxygenase 1 (HO-1), NADH oxidoreductase coenzyme 10 (Ndufa10), thioredoxin (Trx)] and apoptosis-related proteins [B-cell lymphoma 2 (Bcl-2), Bcl-2 associated X protein (Bax), Caspase-3 and cytochrome C (Cytc)] were detected. RESULTS Compared with blank group, the cell morphology of model group was damaged; the levels of LDH, CK and MDA were significantly increased (P<0.01), while the levels of CAT, ComplexⅠ, SOD and GSH-Px and mitochondrial membrane potential were significantly decreased (P<0.01). The content of intracellular ROS and apoptotic rate were significantly increased (P<0.01); the expressions of oxidative stress-related proteins (Keap1, Nrf2, HO-1, Ndufa10 and Trx) and pro- apoptosis proteins (Bax, Caspase-3 and Cytc) were significantly increased (P<0.05), while the expression of anti-apoptotic protein Bcl-2 was significantly decreased (P<0.05). After administration of Bawei chenxiang powder containing serum, the cell morphology improved, and most of the above indexes were significantly reversed (P<0.05 or P<0.01).CONCLUSIONS Bawei chenxiang powder containing serum E-mail:345783110@qq.com has a good protective effect on H9c2 cells damaged by OGD,the mechanism of which is related to the reduction of oxidative damage and inhibition of cell apoptosis.

RESUMO

OBJECTIVES@#Application of ultrashort wave (USW) to rats with cerebral ischemia and reperfusion injury could inhibit the decrease of expression of secretory pathway Ca2+-ATPase 1 (SPCA1), an important participant in Golgi stress, reduce the damage of Golgi apparatus and the apoptosis of neuronal cells, thereby alleviating cerebral ischemia-reperfusion injury. This study aims to investigate the effect of USW on oxygen-glucose deprivation/reperfusion (OGD/R) injury and the expression of SPCA1 at the cellular level.@*METHODS@#N2a cells were randomly divided into a control (Con) group, an OGD/R group, and an USW group. The cells in the Con group were cultured without exposure to OGD. The cells in the OGD/R group were treated with OGD/R. The cells in the USW group were treated with USW after OGD/R. Cell morphology was observed under the inverted phase-contrast optical microscope, cell activity was detected by cell counting kit-8 (CCK-8), apoptosis was detected by flow cytometry, and SPCA1 expression was detected by Western blotting.@*RESULTS@#Most of the cells in the Con group showed spindle shape with a clear outline and good adhesion. In the OGD/R group, cells were wrinkled, with blurred outline, poor adhesion, and lots of suspended dead cells appeared; compared with the OGD/R group, the cell morphology and adherence were improved, with clearer outlines and fewer dead cells in the USW group. Compared with the Con group, the OGD/R group showed decreased cell activity, increased apoptotic rate, and down-regulating SPCA1 expression with significant differences (all P<0.001); compared with the OGD/R group, the USW group showed increased cell activity, decreased apoptotic rate, and up-regulating SPCA1 expression with significant differences (P<0.01 or P<0.001).@*CONCLUSIONS@#USW alleviates the injury of cellular OGD/R, and its protective effect may be related to its up-regulation of SPCA1 expression.
