Abstract This article aims to analyse the relationship between physical activity (PA) environment at schools, sex, age, and obesity in children, using a network approach. This is a cross-sectional study, with 1,200 children (8.1±1.0 years old) from eight public schools in the same municipality. Weight and height measurements were assessed to calculate the Body Mass Index (BMI) and classified as healthier weight or overweight. To assess the PA environment at school, a interview with the school´s manager was conducted. The association between the PA environment at school and obesity was tested using a Network Analysis performed on the Jasp software. Positive associations between BMI and Physical Education classes (0.847), physical education teacher (0.349), break duration (0.564), and indoor sports court (0.662) were observed. Negative associations were seen with sex (-0.212) age (-0.387), extracurricular PA (-0.492), and playground (-0.557). Additionally, the centrality indicators highlighted extracurricular PA (1.789) as the variables with the highest betweenness values, and BMI with the highest closeness (2.239) and strength (1.230) values. Extracurricular PA and the presence of playgrounds in school´s environment are associated with healthier weight in low-income children.

Introduction Treatment of hemophilia A in Brazil is offered to all patients at no cost. However, several unmet medical needs exist. Method In this study, we applied the Delphi method to discuss with seven hemophilia A specialists the challenges that patients and the health system face regarding hemophilia A treatment and opportunities for improvement. Results A consensus was obtained regarding the number of weekly infusions and patient adherence to treatment. The bleeding profile, unfavourable pharmacokinetics (PKs), low adherence and high daily activity were patient profiles that would benefit from using the extended half-life (EHL) recombinant factor VIII (rFVIII). The advantages of treatment with the EHL rFVIII were the lower number of infusions per week, which could increase patient adherence and decrease the risk of bleeds, due to a more constant plasma level, a lower value. Additionally, the EHL rFVIII could improve quality of life, especially in patients with high daily activity, such as adolescents and young adults. The panelists mentioned that EHL rFVIII, if available, could be offered first to the priority group (adolescents between 12 and 19 years old), followed by adults (20 to 64 years old) and elderly people (over 65 years old). Conclusion In summary, the EHL rFVIII offers the optimal prophylaxis by decreasing the dose frequency, increasing the treatment adherence and improving the QoL, without compromising safety and efficacy. cost However exist study improvement profile PKs, PKs , (PKs) halflife half life (EHL rFVIII. .

ABSTRACT Background: To assess the efficacy of applying the endoscopic reference score for EoE (EREFS) in children with symptoms of esophageal dysfunction naïve to proton pump inhibitor (PPI) therapy. Methods: An observational cross-sectional study was conducted by reviewing reports and photographs of upper gastrointestinal endoscopies (UGE) and esophageal biopsies of patients with symptoms of esophageal dysfunction. Patients who were treated with PPI or had other conditions that may cause esophageal eosinophilia were excluded. Results: Of the 2,036 patients evaluated, endoscopic findings of EoE were identified in 248 (12.2%) and more than one abnormality was observed in 167 (8.2%). Among all patients, 154 (7.6%) presented esophageal eosinophilia (≥15 eosinophils per high power field) (P<0.01). In this group, 30 patients (19.5%) had normal endoscopy. In patients with EoE, edema (74% vs 6.5%, P<0.01) and furrows (66.2% vs 2.4%, P<0.01) were more prevalent than in the control group. Association of edema and furrows was more frequent in patients with EoE than in the control group (29.2% vs 1.6%, P<0.01, OR=24.7, CI=15.0-40.5). The presence of more than one endoscopic finding had sensitivity of 80.5%, specificity of 93.4%, positive predictive value (PPV) of 50%, negative predictive value (NPV) of 98.3%, and accuracy of 92.4%. Conclusion: In conclusion, this study showed that endoscopic features suggestive of EoE had high specificity and NPV for diagnosing EoE in children naïve to PPI therapy. These findings highlight the importance of the EREFS in contributing to early identification of inflammatory and fibrostenosing characteristics of EoE, making it possible to identify and to avoid progression of the disease.

RESUMO Contexto: Avaliar a eficácia da aplicação do escore de referência endoscópico para EoE (EREFS) em crianças com sintomas de disfunção esofágica sem tratamento prévio com inibidores da bomba de prótons (IBP). Métodos: Foi realizado um estudo transversal observacional por meio de revisão de laudos e fotos de endoscopia digestiva alta (EDA) e biópsias de esôfago de pacientes com sintomas de disfunção esofágica. Pacientes tratados com IBP ou com outras condições que podem causar eosinofilia esofágica foram excluídos. Resultados: Dos 2.036 pacientes avaliados, os achados endoscópicos de EoE foram identificados em 248 (12,2%) e mais de uma anormalidade foi observada em 167 (8,2%). Entre todos os pacientes, 154 (7,6%) apresentaram eosinofilia esofágica (≥15 eosinófilos por campo de grande aumento) (P<0,01). Nesse grupo, 30 pacientes (19,5%) apresentaram endoscopia normal. Em pacientes com EoE, edema (74% vs 6,5%, P<0,01) e linhas verticais (66,2% vs 2,4%, P<0,01) foram mais prevalentes quando comparados ao grupo controle. A associação de edema e linhas verticais foi mais frequente em pacientes com EoE do que no grupo controle (29,2% vs 1,6%, P<0,01, OR=24,7, IC=15,0-40,5). A presença de mais de um achado endoscópico teve sensibilidade de 80,5%, especificidade de 93,4%, valor preditivo positivo de 50%, valor preditivo negativo de 98,3% e acurácia de 92,4%. Conclusão: Em conclusão, esse estudo mostrou que as características endoscópicas sugestivas de EoE apresentam especificidade e VPN elevados para o diagnóstico da enfermidade em crianças sem tratamento prévio com IBP. Estes achados reforçam a importância do EREFS em contribuir para a identificação precoce de características inflamatórias e fibroestenosantes, possibilitando identificar e evitar a progressão da doença.

The aim of this work was to extract and characterize pectin from lyophilized noni pulp (Morinda citrifolia Linn.) at three different pHs using different extractor agents and to evaluate anti-viral activity. The extraction of high yield (acid extraction) was subjected to sulfation procedure. Fourier transform infrared spectroscopy and proton nuclear magneticresonance analysis were used to calculate the degree of methylation of pectin from acid extraction and its sulfated derivative. The data obtained for the degree of methylation of noni pectin and sulfated pectin were 30.3 and 30.7, respectively. Pectin was subjected to acute oral toxicity testing in mice. The results showed that pectin had a pro-inflammatory effect, and sulfated pectin had an anti-inflammatory effect. Both pectins were also evaluated for herpes simplex virus activity in vitro, and although they successfully inhibited virus replication, the sulfated pectins were cytotoxic. Morinda Linn.

ABSTRACT Objective: To examine the physical function and respiratory muscle strength of patients - who recovered from critical COVID-19 – after intensive care unit discharge to the ward on Days one (D1) and seven (D7), and to investigate variables associated with functional impairment. Methods: This was a prospective cohort study of adult patients with COVID-19 who needed invasive mechanical ventilation, non-invasive ventilation or high-flow nasal cannula and were discharged from the intensive care unit to the ward. Participants were submitted to Medical Research Council sum-score, handgrip strength, maximal inspiratory pressure, maximal expiratory pressure, and short physical performance battery tests. Participants were grouped into two groups according to their need for invasive ventilation: the Invasive Mechanical Ventilation Group (IMV Group) and the Non-Invasive Mechanical Ventilation Group (Non-IMV Group). Results: Patients in the IMV Group (n = 31) were younger and had higher Sequential Organ Failure Assessment scores than those in the Non-IMV Group (n = 33). The short physical performance battery scores (range 0 - 12) on D1 and D7 were 6.1 ± 4.3 and 7.3 ± 3.8, respectively for the Non-Invasive Mechanical Ventilation Group, and 1.3 ± 2.5 and 2.6 ± 3.7, respectively for the IMV Group. The prevalence of intensive care unit-acquired weakness on D7 was 13% for the Non-IMV Group and 72% for the IMV Group. The maximal inspiratory pressure, maximal expiratory pressure, and handgrip strength increased on D7 in both groups, but the maximal expiratory pressure and handgrip strength were still weak. Only maximal inspiratory pressure was recovered (i.e., > 80% of the predicted value) in the Non-IMV Group. Female sex, and the need and duration of invasive mechanical were independently and negatively associated with the short physical performance battery score and handgrip strength. Conclusion: Patients who recovered from critical COVID-19 and who received invasive mechanical ventilation presented greater disability than those who were not invasively ventilated.

RESUMO Objetivo: Examinar a função física e a força muscular respiratória de pacientes que se recuperaram da COVID-19 grave após a alta da unidade de terapia intensiva para a enfermaria nos Dias 1 e 7 e investigar as variáveis associadas ao comprometimento funcional. Métodos: Trata-se de estudo de coorte prospectivo de pacientes adultos com COVID-19 que necessitaram de ventilação mecânica invasiva, ventilação mecânica não invasiva ou cânula nasal de alto fluxo e tiveram alta da unidade de terapia intensiva para a enfermaria. Os participantes foram submetidos aos testes Medical Research Council sum-score, força de preensão manual, pressão inspiratória máxima, pressão expiratória máxima e short physical performance battery. Os participantes foram agrupados em dois grupos conforme a necessidade de ventilação mecânica invasiva: o Grupo Ventilação Mecânica Invasiva (Grupo VMI) e o Grupo Não Ventilação Mecânica Invasiva (Grupo Não VMI). Resultados: Os pacientes do Grupo VMI (n = 31) eram mais jovens e tinham pontuações do Sequential Organ Failure Assessment mais altas do que os do Grupo VMI (n = 33). As pontuações do short physical performance battery (intervalo de zero a 12) nos Dias 1 e 7 foram 6,1 ± 4,3 e 7,3 ± 3,8, respectivamente para o Grupo Não VMI, e 1,3 ± 2,5 e 2,6 ± 3,7, respectivamente para o Grupo VMI. A prevalência de fraqueza adquirida na unidade de terapia intensiva no Dia 7 foi de 13% para o Grupo Não VMI e de 72% para o Grupo VMI. A pressão inspiratória máxima, a pressão expiratória máxima e a força de preensão manual aumentaram no Dia 7 em ambos os grupos, porém a pressão expiratória máxima e a força de preensão manual ainda eram fracas. Apenas a pressão inspiratória máxima foi recuperada (ou seja, > 80% do valor previsto) no Grupo Não VMI. As variáveis sexo feminino, e necessidade e duração da ventilação mecânica invasiva foram associadas de forma independente e negativa à pontuação do short physical performance battery e à força de preensão manual. Conclusão: Os pacientes que se recuperaram da COVID-19 grave e receberam ventilação mecânica invasiva apresentaram maior incapacidade do que aqueles que não foram ventilados invasivamente. No entanto, os dois grupos de pacientes apresentaram melhora funcional marginal durante a fase inicial de recuperação, independentemente da necessidade de ventilação mecânica invasiva. Esse resultado pode evidenciar a gravidade da incapacidade causada pelo SARS-CoV-2. Objetivo COVID19 COVID 19 COVID-1 Métodos Tratase Trata sumscore, sumscore sum score, score sum-score .

Abstract Difficult airway management in pediatrics during anesthesia represents a major challenge, requiring a careful approach, advanced technical expertise, and accurate protocols. The task force of the Brazilian Society of Anesthesiology (SBA) presents a report containing updated recommendations for the management of difficult airways in children and neonates. These recommendations have been developed based on the consensus of a panel of experts, with the objective of offering strategies to overcome challenges during airway management in pediatric patients. Grounded in evidence published in international guidelines and expert opinions, the report highlights crucial steps for the appropriate management of difficult airways in pediatrics, encompassing assessment, preparation, positioning, pre-oxygenation, minimizing trauma, and, paramountly, the maintenance of arterial oxygenation. The report also delves into additional strategies involving the use of advanced tools, such as video laryngoscopy, flexible intubating bronchoscopy, and supraglottic devices. Emphasis is placed on the simplicity of implementing the outlined recommendations, with a focus on the significance of continuous education, training through realistic simulations, and familiarity with the latest available technologies. These practices are deemed essential to ensure procedural safety and contribute to the enhancement of anesthesia outcomes in pediatrics. challenge approach expertise protocols SBA (SBA neonates experts patients opinions assessment preparation positioning preoxygenation, preoxygenation pre oxygenation, oxygenation pre-oxygenation trauma paramountly tools laryngoscopy bronchoscopy devices education simulations technologies

Abstract Background: Testosterone deficiency (TD) is a prevalent condition in our midst and still very neglected. Arterial hypertension (AH) is one of the possible associated factors. Objectives: To determine the prevalence of TD in a hypertensive male population and the factors associated with its occurrence, such as age, time since hypertension diagnosis, number of antihypertensive classes, body mass index (BMI), diabetes, dyslipidemia, chronic kidney disease (CKD), positive symptoms of TD (positive ADAM questionnaire) and use of spironolactone. Methods: Cross-sectional study with administration of the ADAM questionnaire, assessment of biochemical, clinical, and anthropometric data. Patients were stratified into DT and normal testosterone groups. Categorical variables were compared using the chi-squared test and continuous variables using the Mann-Witney test; variables with significance (p<0,05) were analyzed by multivariable linear regression. Results: The prevalence of TD was 26.36%. There was an association between TD and body mass index (BMI) (p=0.0007) but there was no association with age (p=0.0520), time of hypertension diagnosis (p=0.1418), number of classes of antihypertensive drugs (p=0.732), diabetes (p=0.1112); dyslipidemia (p=0.3888); CKD (p=0.3321); use of spironolactone (p=0.3546) or positive ADAM questionnaire (p=0.2483). Conclusions: TD was highly prevalent and positively associated with BMI. Total testosterone (TT) declined by 8.44ng/dL with a one unit increase in BMI and dropped by 3.79ng/dL with a one-year increase in age.

Resumo Fundamento: A deficiência de testosterona (DT) é uma condição prevalente em nosso meio e ainda muito negligenciada. A hipertensão arterial (HA) é um de seus possíveis fatores associados. Objetivos: Determinar a prevalência de DT em uma população masculina hipertensa e os fatores associados à sua ocorrência, como idade, tempo de diagnóstico de HA, número de classes de anti-hipertensivos, índice de massa corporal (IMC), diabetes, dislipidemia, doença renal crônica (DRC), sintomas positivos de DT (questionário ADAM positivo) e uso de espironolactona. Métodos: Estudo transversal com aplicação do questionário ADAM, e avaliação de dados bioquímicos, clínicos e antropométricos. Os pacientes foram estratificados em grupos de DT e testosterona normal. As variáveis categóricas foram comparadas pelo teste do qui-quadrado e as variáveis contínuas pelo teste de Mann-Witney; as variáveis com significância (p<0,05) foram submetidas à regressão linear multivariada. Resultados: A prevalência de DT foi de 26,8%. Houve associação entre DT e IMC (p=0,0007), mas não houve com idade (p=0,0520), tempo de diagnóstico de HA (p=0,1418), número de classes de anti-hipertensivos (p=0,0732), diabetes (p=0,1112); dislipidemia (p=0,3888); presença de DRC (p=0,3321); uso de espironolactona (p=0,3546) e questionário ADAM positivo (p=0,2483). Conclusões: A prevalência de DT foi alta e houve associação positiva com IMC. A testosterona total (TT) declinou 8,44 ng/dL com o aumento de 1 kg/m2 no IMC e caiu 3,79 ng/dL com o avanço em um ano na idade.

SUMMARY OBJECTIVE: The aim of this study was to analyze possible alterations (morphological and inflammatory) in the ocular cells of fetuses from mothers with insulin resistance exposed to saturated fatty acids through the period of pregnancy. METHODS: Wistar female rats were induced to develop insulin resistance before pregnancy. Fetuses' skulls were collected on the 20th day of intrauterine life. The rats were separated on the first day of management into two groups according to the diet applied: control group (C): diet containing soybean oil as a source of fat; and saturated fatty acid group (S): diet containing butter as a source of fat. RESULTS: Histological and immunohistochemical analyses have been conducted. The immunohistochemical analyses of interleukin 6, suppressor of cytokine signaling, 3 and signal transducer and activator of transcription 3 did not demonstrate alterations in the expression of proteins in the fetuses of mothers fed with a saturated fatty diet. Moreover, no histopathological changes were noticed between groups. CONCLUSION: The saturated fatty diet does not induce tissue changes or activate the Janus kinase/signal transducer and activator of transcription signaling pathway during eye development in the fetuses of mothers with insulin resistance.

ABSTRACT BACKGROUND AND OBJECTIVES: The locus of control (LC) of pain is the perception of the individual about pain control. The investigation of the relationship between LC, dependence and depression in elderly patients is of great importance given the high prevalence of chronic diseases among this population. The objective of this study was to analyze the association between LC of pain in elderly patients and the level of dependence and prevalence of depression. METHODS: Ninety-one elderly individuals, aged over 60 years, were selected from the Association of Retirees, Pensioners, and Elderly of Lavras and Region (AAPIL) and all participants underwent a comprehensive anamnesis to effectively describe and characterize the sample. The Health Locus of Control Multidimensional Scale was used to assess perception of pain, the Yesavage Geriatric Depression Scale was used to determine the prevalence of depression, and Katz Index to evaluate functional capacity. Chi-square test was used to analyze nominal variables with a 95% level of significance. RESULTS: The majority of the elderly participants (83.5%) reported experiencing chronic pain, while 85.7% had no suspected depression. Internal control was the most prevalent type of LC among participants, and there was no significant relationship between LC of pain and depression. CONCLUSION: Findings suggest that the type of LC of pain reported by the elderly participants in this study does not significantly interfere with the likelihood of depression. These results contribute to the understanding of the relationship between LC, dependence, and depression among senior patients and may inform interventions to improve their quality of life.

RESUMO JUSTIFICATIVA E OBJETIVOS: O lócus de controle (LC) da dor é a percepção do indivíduo sobre o controle da dor. A investigação da relação entre LC, dependência e depressão em idosos é de grande importância dada a alta prevalência de doenças crônicas nessa população. O objetivo deste estudo foi analisar a associação entre LC de dor em idosos, o grau de dependência e a prevalência de depressão. MÉTODOS: Noventa e um indivíduos idosos com idade superior a 60 anos foram selecionados na Associação de Aposentados, Pensionistas e Idosos de Lavras e Região (AAPIL), e todos os participantes passaram por uma anamnese abrangente para descrever e caracterizar efetivamente a amostra. A Escala Multidimensional de Lócus de Controle da Saúde foi usada para avaliar a percepção de dor, a Escala de Depressão Geriátrica Yesavage para determinar a prevalência de depressão e o Índice de Katz para avaliar a capacidade funcional. O teste Qui-quadrado foi utilizado para analisar variáveis nominais com nível de significância de 95%. RESULTADOS: A maioria dos idosos participantes (83,5%) relatou sentir dor crônica, enquanto 85,7% não tinham suspeita de depressão. O controle interno foi o tipo de LC mais prevalente entre os participantes, não havendo relação significativa entre LC de dor e depressão. CONCLUSÃO: Os achados sugerem que o tipo de LC da dor relatado pelos idosos participantes deste estudo não interferiu significativamente a probabilidade de depressão. Esses resultados contribuem para a compreensão da relação entre LC, dependência e depressão entre pacientes idosos e podem auxiliar em intervenções para melhorar sua qualidade de vida.

Heterocycles of the isoxazolone class stand out in the pharmaceutical field because they have numerous biological properties, such as antioxidant, antifungal and antibacterial properties. Thus, isoxazole derivatives have attracted the attention of organic researchers, and several procedures have been developed to obtain these compounds. The present study aimed to synthesize 17 derivatives of isoxazol-5(4H)-ones using a multicomponent reaction catalyzed by an acidic ionic liquid, which allowed yields from 20-96% of the products. To evaluate the bioactivity of the compounds, the synthesized derivatives were analyzed at various concentrations against bacteria and fungi; the derivatives, in general, showed a moderate activity of 125 μg mL-1 against the fungus Candida tropicalis (ATCC 13803) and four derivatives showed an inhibition of < 15.62 μg mL-1 for Gram-positive Staphylococcus epidermidis (ATCC 12228). Furthermore, the antioxidant potential of the derivatives was evaluated by measuring their ability to scavenge 2,2-diphenyl-1-picryl-hydrazyl (DPPH) free radicals, resulting in a remarkable reduction percentage of up to 81.06%. To gain further insights into the structure-activity relationships, a principal component analysis was conducted to classify the compounds into active and inactive classes, providing a comprehensive understanding of their bioactivity profiles. properties Thus researchers 1 isoxazol54Hones isoxazolHones isoxazol 5 4H ones H liquid 2096% 2096 20 96% 96 20-96 products fungi general 12 mL1 mL mL- ATCC 13803 1562 15 62 15.6 Grampositive Gram positive 12228. 12228 . 12228) Furthermore 2,2diphenyl1picrylhydrazyl 22diphenyl1picrylhydrazyl diphenylpicrylhydrazyl 2,2 diphenyl picryl hydrazyl 2 DPPH (DPPH radicals 8106 81 06 81.06% structureactivity structure relationships classes profiles Hones 209 9 20-9 1380 156 6 15. 1222 2diphenyl1picrylhydrazyl picrylhydrazyl 22 2, 810 8 0 81.06 20- 138 122 81.0 13 81.

The potential of four commercial clones of unripe acerola fruit was investigated regarding a source of nutraceuticals and functional foods for industrial use. The chemical profiling of the BRS 235-Apodi, BRS 236-Cereja, BRS 237-Roxinha, and BRS 238-Frutacor clones was determined by the ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-QTOF/MS-MS) technique coupled to multivariate statistical analysis, which were then correlated to ABTS•+ radical capture (2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) and ferric reducing antioxidant power (FRAP) assays in order to measure the antioxidant capacity. A total of 24 bioactive compounds were identified, including high amounts of quercetin-O-hexoside, astilbin, and apigenin, which were correlated to three clones (BRS 235, BRS 237, and BRS 238). On the other hand, the BRS 236 clone presented high contents of ascorbic acid, iso-ascorbic acid, citric acid, procyanidin B trimer, rutin, phenolic compounds, and antioxidant activity. These compounds were additionally found to be strongly associated with the antioxidant capacity of unripe acerola fruits. Therefore, the present study revealed that BRS 236 is a promising clone as an antioxidant source to be used as a functional food or ingredient. use 235Apodi, 235Apodi Apodi 235 Apodi, 235-Apodi 236Cereja, 236Cereja Cereja Cereja, 236-Cereja 237Roxinha, 237Roxinha Roxinha 237 Roxinha, 237-Roxinha 238Frutacor Frutacor 238 ultrahigh ultra chromatographyquadrupole chromatography quadrupole timeofflight time flight UPLCQTOF/MSMS UPLCQTOFMSMS UPLC QTOF/MS MS QTOF (UPLC-QTOF/MS-MS analysis ABTS ABTS• 2,2azinobis3ethylbenzothiazoline6sulfonic 22azinobis3ethylbenzothiazoline6sulfonic azinobisethylbenzothiazolinesulfonic 2,2 azino bis 3 ethylbenzothiazoline 6 sulfonic 2 acid FRAP (FRAP identified quercetinOhexoside, quercetinOhexoside quercetin O hexoside, hexoside quercetin-O-hexoside astilbin apigenin 238. . 238) hand 23 isoascorbic iso trimer rutin activity fruits Therefore ingredient UPLCQTOF MSMS QTOFMS 2azinobis3ethylbenzothiazoline6sulfonic azinobis 22 2,
