RESUMO

Breast cancer stands as the most prevalent type of tumor and a significant contributor to cancer-related deaths. Among its various subtypes, triple-negative breast cancer (TNBC) presents the worst prognosis due to its aggressive nature and the absence of effective treatments. Crotoxin, a protein found in the venom of Crotalus genus snakes, has demonstrated notable antitumor activity against aggressive solid tumors. However, its application has been hindered by substantial toxicity in humans. In efforts to address this challenge, Crotoxin B-derived peptides were synthesized and evaluated in vitro for their antitumor potential, leading to the discovery of 3-NAntC. Treatment with 3-NAntC at 1 µg/mL for 72 h notably reduced the viability of MDA-MB-231 cells to 49.0 ± 17.5% (p < 0.0001), while exhibiting minimal impact on the viability of HMEC cells (98.2 ± 13.8%) under the same conditions. Notably, 3-NAntC displayed superior antitumoral activity in vitro compared to cisplatin and exhibited a similar effect to doxorubicin. Further investigation revealed that 3-NAntC decreased the proliferation of MDA-MB-231 cells and induced G2/M phase arrest. It primarily prompted optimal cell death by apoptosis, with a lower incidence of the less desirable cell death by necrosis in comparison to doxorubicin. Additionally, 3-NAntC demonstrated low LDH release, and its cytotoxicity remained unaffected by the autophagy inhibitor 3-MA. In an in vivo zebrafish model, 3-NAntC exhibited excellent tolerability, showing no lethal effects and a low rate of malformations at high doses of up to 75 mg/mL. Overall, 3-NAntC emerges as a novel synthetic peptide with promising antitumor effects in vitro against TNBC cells and low toxicity in vivo.

RESUMO

OBJECTIVE: Evaluate the influence of the BsmI polymorphism of the vitamin D receptor gene on vitamin D levels, and inflammatory and oxidative stress markers in patients with Cystic Fibrosis supplemented with cholecalciferol megadose. METHODS: We performed a single-arm, non-randomized pre- and post-study of 17 patients aged 5 to 20 years with cystic fibrosis diagnosed with vitamin D insufficiency/deficiency 25-hydroxy vitamin< 30 ng/mL. Individuals were genotyped for the BsmI polymorphism of the vitamin D receptor gene and all received cholecalciferol supplementation of 4,000 IU daily for children aged 5 to 10 years and 10,000 IU for children over 10 years of age for 8 weeks. Interviews were conducted with personal data, sun exposure, anthropometric and blood samples of 25-hydroxy vitamin parathormone, serum calcium, ultrasensitive C-reactive protein, alpha 1 acid glycoprotein, total antioxidant capacity, malondialdehyde and kidney and liver function. Inter- and intra-group assessment was assessed by paired t-test Anova test or its non-parametric counterparts. RESULTS: The individuals were mostly male and reported no adverse effects from the use of supplementation, 64 % had 25-hydroxy vitamin levels >30 ng/mL. Patients with BB and Bb genotypes showed increased serum levels of 25-hydroxy vitamin. The group with BB genotype showed a reduction in alpha 1 acid glycoprotein. And individuals with the bb genotype had high levels of malondialdehyde compared to the pre-intervention time. CONCLUSION: It is concluded that variations of the BsmI polymorphism of the vitamin D receptor gene have different responses in vitamin D levels and markers of inflammation and oxidative stress.

RESUMO

Much is known about the role of aeroallergens in asthma, but little is described about the damage caused by inhaled pollutants and irritants to the respiratory epithelium. In this context, the most frequent pollutants and irritants inhaled in the home environment were identified, describing the possible repercussions that may occur in the respiratory tract of the pediatric population with asthma and highlighting the role of the caregiver in environmental control through a salutogenic perspective. Searches were carried out in the MEDLINE/PubMed, Web of Science, Lilacs and Scopus databases for articles considered relevant for the theoretical foundation of this integrative review, in which interactions between exposure to pollutants and inhaled irritants and lung involvement. Articles published in the last 10 years that used the following descriptors were considered: air pollution; tobacco; particulate matter; disinfectants; hydrocarbons, fluorinated; odorants; chloramines; pesticide; asthma; and beyond Antonovsky's sense of coherence. Exposure to smoke and some substances found in cleaning products, such as benzalkonium chloride, ethylenediaminetetraacetic acid and monoethanolamine, offer potential risks for sensitization and exacerbation of asthma. The vast majority of the seven main inhaled products investigated provoke irritative inflammatory reactions and oxidative imbalance in the respiratory epithelium. In turn, the caregiver's role is essential in health promotion and the clinical control of paediatric asthma. From a salutogenic point of view, pollutants and irritants inhaled at home should be carefully investigated in the clinical history so that strategies to remove or reduce exposures can be used by caregivers of children and adolescents with asthma.

RESUMO

INTRODUCTION: The third-generation of aromatase inhibitors (AIs)-Exemestane (Exe), Letrozole (Let), and Anastrozole (Ana)-is the main therapeutic approach applied for estrogen receptor-positive (ER+) breast cancer (BC), the most common neoplasm in women worldwide. Despite their success, the development of resistance limits their efficacy. Genistein (G), a phytoestrogen present in soybean, has promising anticancer properties in ER+ BC cells, even when combined with anticancer drugs. Thus, the potential beneficial effects of combining G with AIs were investigated in sensitive (MCF7-aro) and resistant (LTEDaro) BC cells. METHODS: The effects on cell proliferation and expression of aromatase, ERα/ERß, and AR receptors were evaluated. RESULTS: Unlike the combination of G with Ana or Let, which negatively affects the Ais' therapeutic efficacy, G enhanced the anticancer properties of the steroidal AI Exe, increasing the antiproliferative effect and apoptosis relative to Exe. The hormone targets studied were not affected by this combination when compared with Exe. CONCLUSIONS: This is the first in vitro study that highlights the potential benefit of G as an adjuvant therapy with Exe, emphasizing, however, that soy derivatives widely used in the diet or applied as auxiliary medicines may increase the risk of adverse interactions with nonsteroidal AIs used in therapy.

RESUMO

Extrapulmonary tuberculosis associated with immune thrombocytopenia (ITP) is extremely rare. A likely association between ITP and pulmonary and lymph node tuberculosis was reported in a 29-year-old male patient. His platelet count decreased to 4,000/µL. Chest tomography revealed mediastinal adenomegaly, lymph node clusters in the aorta, and consolidation in the left upper lung lobe. Immunoglobulin and methylprednisolone were administered intravenously. The histopathology of the left upper lung lobe confirmed tuberculosis. The rifampicin/isoniazid/pyrazinamide/ethambutol regimen was initiated, and the corticosteroids were tapered off. This case suggests an association of tuberculosis with ITP, since the platelet count effectively normalized after tuberculosis treatment.

RESUMO

Introduction: cystic fibrosis is a disease that causes inflammation, oxidative stress and metabolic changes that lead to nutrient deficiency, such as vitamin D deficiency. On the other hand, it is suggested that vitamin D has anti-inflammatory and antioxidant actions. Objective: to evaluate the prevalence of hypovitaminosis D and the association between serum 25 hydroxyvitamin D levels with markers of oxidative stress and inflammation in patients with cystic fibrosis. Method: a cross-sectional study was carried out with 48 patients with cystic fibrosis including children, adolescents and adults in the northeast region of Brazil. Blood collection was performed for analysis of 25-hydroxyvitamin D, calcium, parathyroid hormone, inflammatory process (C-reactive protein (CRP) and alpha-1-acid glycoprotein-A1 (A1GPA)) and oxidative stress (malondialdehyde (MDA) and total antioxidant capacity (CAOT)). The statistical analysis was performed using the “Statistical Package for the Social Sciences”, adopting a significance level of p < 0.05. Results: Vitamin D insufficiency/deficiency was found in 64.6 % of patients. After multiple linear regression analysis, MDA showed an inverse association with blood values of 25-Hydroxyvitamin D (p < 0.05) conditioned by the presence of inflammatory process markers. When only oxidative stress was evaluated, this association disappeared. Conclusion: in conclusion, there was a high prevalence of hypovitaminosis D, with 25(OH)D levels associated with greater oxidative stress when combined with inflammatory markers. Improved vitamin D levels may be an alternative to reduce the damage caused by excess oxidative stress and inflammation in CF patients. (AU)


Introducción: la fibrosis quística es una enfermedad que cursa con inflamación, estrés oxidativo y cambios metabólicos que conducen a deficiencia de nutrientes como la vitamina D. Por otro lado, se sugiere que la vitamina D tiene acción antiinflamatoria y antioxidante. Objetivo: evaluar la prevalencia de hipovitaminosis D y la asociación entre los niveles séricos de 25 hidroxivitamina D con los marcadores de estrés oxidativo e inflamación en pacientes con fibrosis quística. Método: estudio transversal realizado con 48 pacientes con fibrosis quística, niños, adolescentes y adultos, de la región nordeste de Brasil. Se realizó una extracción de sangre para el análisis de 25-hidroxivitamina D, calcio, hormona paratiroidea, proceso inflamatorio (proteína C-reactiva [PCR] y alfa-1-glucoproteína ácida-A1 [A1GPA]) y estrés oxidativo (malondialdehído [MDA] y capacidad antioxidante total [CAOT]). El análisisestadístico se realizó utilizando el “Paquete Estadístico para las Ciencias Sociales”, adoptando un nivel de significancia de p < 0,05. Resultados: se encontró insuficiencia/deficiencia de vitamina D en el 64,6 % de los pacientes. Después de un análisis de regresión lineal múltiple, la MDA mostró una asociación inversa con los valores sanguíneos de 25-hidroxivitamina D (p < 0,05) condicionado a la presencia de marcadores de proceso inflamatorio; cuando solo se evalúa el estrés oxidativo, esta asociación desaparece. Conclusión: en conclusión, hubo una alta prevalencia de hipovitaminosis D, con niveles de 25(OH)D asociados a mayor estrés oxidativo cuando se combina con marcadores inflamatorios. La mejora de los niveles de vitamina D puede ser una alternativa para reducir el daño causado por el exceso de estrés oxidativo y la inflamación en pacientes con FQ. (AU)

RESUMO

BACKGROUND: Physical exercise is prescribed in populations with chronic diseases, but data are scarce in the liver transplantation (LT) setting. OBJECTIVE: The aim of this study was to evaluate changes in forced expiratory volume in the first second, forced vital capacity, maximal inspiratory pressure, maximal expiratory pressure, 6-minute walking test (6MWT), 6-minute step test (6MST), Duke Activity Status Index, VO2 (mL/kg/min), and health-related quality of life (in patients submitted to a rehabilitation program, comprising physical exercise training, breathing techniques, and educational sessions after LT. METHODS: This cohort study enrolled patients to an 8-week period of thrice weekly comprehensive supervised rehabilitation program after 1 month of LT. A nonrandomized control cohort of LT patients were selected to match the rehabilitation group based on specific demographic data and severity of disease. RESULTS: The rehabilitation group, compared with the control group, showed a significant improvement in respiratory parameters (forced vital capacity [0.33L vs 0.13L,P < .01]); exercise capacity (6MWT and 6MST 71.1 vs 34.1 meters; and 30.5 vs 7.5 steps; respectively P < .01); Duke Activity Status Index scores and VO2 (21.3 vs 10.2 and 9 vs 4.3; respectively P < .01); respiratory muscle strength (maximal inspiratory pressure 21.1 vs 15.1 cmH2O and maximal expiratory pressure 21.2 vs 10.2 cmH2O; P < .01); and quality of life (SF-36 physical component summary 12.4 vs 2.9 P < .01). CONCLUSION: These data suggest that improvements in physical fitness, respiratory parameters, and quality of life are achieved with a comprehensive rehabilitation program initiated early after LT.

RESUMO

Resumo Elevada a um patamar de legitimidade juntamente com a ordem social global do capitalismo, a ciência moderna descreve e prescreve padrões sobre a ética do cuidado, a estética dos corpos e os desenhos das políticas de saúde. Este estudo objetiva analisar o campo da saúde à luz das teorias pós-coloniais e de políticas públicas, apresentando o desafio da interdisciplinaridade como contraponto ao establishment. Trata-se de uma revisão compreensiva de literatura sobre as políticas públicas e as teorias pós-coloniais, explorando produções da área com o intuito de desvelar dinâmicas e tendências atuais. Para as análises, adotou-se um referencial teórico decolonial visando explorar perspectivas da ética, estética e política no campo da saúde. A dimensão cuidadora do trabalho em saúde tem sido minimizada em detrimento de um profissionalismo permeado de distanciamento emocional e neutralidade, que está cada vez mais centrado em avanços tecnológicos. Na busca por "cuidado à saúde", os indivíduos carregam demandas social e cientificamente construídas, tendo seus saberes, muitas vezes, deslegitimados. Perante a agenda neoliberal em curso torna-se imperativo discernir os desafios que cercam o sistema saúde brasileiro e fortalecer os saberes culturais locais.


Abstract Raised to a level of legitimacy in synch with the global social order of capitalism, modern science describes and prescribes standards for the ethics of care, aesthetic consideration of bodies, and for the layouts of health policies. This study aims to analyze the health field in the light of postcolonial and public policy theories, presenting the challenge of interdisciplinarity as a counterpoint to the establishment. This is a comprehensive review of literature on public policies and postcolonial theories, exploring the main productions of the area in order to unveil current dynamics and trends. A decolonial theoretical framework was adopted to explore perspectives of ethics, aesthetics and politics in the health field. The caring practices dimension of health work has been minimized in detriment of a professionalism impregnated by emotional distancing and neutrality, which is increasingly focus on technological innovations. In search for "health care", the individuals carry socially and scientifically constructed demands, but their knowledge is often delegitimized. Given the current neoliberal agenda, it is imperative to discern the challenges surrounding the Brazilian health system and to strengthen local cultural knowledge.

RESUMO

Introduction: Studying highly vulnerable areas is challenging, but it can support intersectoral actions to tackle the social inequalities prevalent therein.Objective: This research explores the relationship between the central constituents of intersectoral collaborations and the positive results of intersectoral actions in areas of high social vulnerability in São Paulo, Brazil. It also analyzes the perception of professionals in basic health units (BHU) regarding the results related to those actions.Methods: This study employed methodological triangulation and the mixed method sequential explanatory strategy. First, we applied an online form validated by face and content for BHU managers. Then, we used the SPSS Statistics software to perform nonparametric tests. Statistical significance was set at p < 0.05, and 95% confidence intervals and phi coefficients were calculated. After identifying the units that carried out intersectoral actions with different partners, we conducted focus groups in four of them with 26 health professionals until saturation. Finally, we integrated quantitative and qualitative data.Results: The bivariate analysis showed that the creation of healthy habits and environmental improvements were associated with the central components of intersectoral partnerships. The content analysis presented steps to elaborate the actions and arrive at the results from the central elements. Integration of the results explained how the results related to the actions were elaborated, considering the central elements of the collaborative processes.Conclusions: Partners negotiate with patients or communities to adhere to the care provided through the collaborative process. However, they recognized that they needed to evaluate the proposed actions regularly.


Introdução: Estudar áreas de alta vulnerabilidade é desafiador, mas pode subsidiar ações intersetoriais para o enfrentamento das desigualdades sociais prevalentes nestas.Objetivo: Esta pesquisa explora a relação entre os constituintes centrais das colaborações intersetoriais e os resultados positivos das ações intersetoriais em áreas de alta vulnerabilidade social em São Paulo, Brasil. Também analisa a percepção dos profissionais das Unidades Básicas de Saúde sobre os resultados relacionados a essas ações.Método: Aplicamos uma triangulação de métodos. A estratégia explicativa sequencial de método misto foi utilizada seguindo os seguintes passos: Primeiramente, aplicamos um formulário online validado por face e conteúdo para gestores de UBS, e 60,7% dos gestores responderam. Utilizou-se o software SPSS Statistic para realizar o teste não paramétrico. Valores de p <= 0,05 foram considerados estatisticamente significantes. O intervalo de confiança de 95% e o coeficiente Phi também foram calculados. Após identificar as Unidades que realizavam ações intersetoriais com diferentes parceiros, realizamos grupos focais em quatro delas com a participação de 26 profissionais de saúde até a saturação. Por fim, integramos os dados quantitativos e qualitativos.Resultados: A análise bivariada mostrou que a criação de hábitos saudáveis e melhorias ambientais estiveram associadas aos elementos centrais que constituem as parcerias intersetoriais com significância estatística (p <= 5). A análise de conteúdo apresentou os passos para elaborar as ações e chegar aos resultados a partir dos elementos centrais. Ao integrar os resultados, respondemos como foram elaborados os resultados relacionados às ações, considerando os elementos centrais dos processos colaborativos.Conclusão: Os parceiros intersetoriais negociam com os pacientes ou comunidades a adesão aos cuidados sugeridos pelo processo colaborativo. No entanto, reconhecem que precisam avaliar regularmente as ações propostas.

RESUMO

Aglycone isoflavones are estrogen-like bioactive compounds found in low amounts in soybean, which are increased by biotransformation processes. This study investigated two biotransformation processes of soybean extracts with Aspergillus awamori fungus, evaluating aglycone content and capability of stimulation of collagen-I deposition. Isoflavones were quantified via HPLC; cytotoxicity of biotransformed extracts toward mouse and human fibroblasts was evaluated via NRU and apoptosis/necrosis assays; and collagen-I deposition was measured through Western blot, immunofluorescence, and immunoassay. BSE-2 was the biotransformed soybean extract with the highest aglycone content and did not decrease viability or demonstrated cytotoxicity to either L929 or HDFa cells. BSE-2, at the optimal concentration of 1.33 µg/mL, increased substantially collagen-I amount in HDFa intracellular matrix compared to non-biotransformed soybean extract (NBSE) and immunoassay demonstrated that the extracellular deposition was mostly inhibited by BSE-2 concentrations, except at 1.33 µg/mL. Hence, biotransformed soybean extract by the enzymatic filtrate of Aspergillus awamori fungus demonstrated a high nutricosmetic potential, showing safeness and effective collagen-I augmentation.

Resumo O artigo objetivou descrever a percepção de alunos com deficiência da Universidade Federal do Pará (UFPA) que apresentaram níveis distintos de estresse. Participaram do estudo 11 alunos dos 29 com estresse e 8 dos 21 sem estresse. Um questionário sociodemográfico, a Escala de Estresse Percebido e o roteiro de entrevista foram aplicados para identificar o que causa o estresse no contexto acadêmico. Os alunos com elevados níveis de estresse foram menos positivos do que os estudantes com baixos níveis de estresse. Concluiu-se que tanto os estudantes com níveis elevados de estresse quanto os com níveis baixos estão sujeitos a terem problemas emocionais e físicos quando o contexto universitário não apresenta uma acessibilidade adequada às suas necessidades especiais.


Abstract The article aimed to describe the perception of students with disabilities at the Federal University of Pará who presented different levels of stress. Eleven of the 29 students with stress and 8 of the 21 without stress participated in the study. A sociodemographic questionnaire, the Perceived Stress Scale and the interview script were applied to identify what causes stress in the academic context. Students with high levels of stress were less positive than the ones with low levels of stress. It was concluded that both students with high levels of stress and with low levels of stress have emotional and physical problems when the university context does not provide adequate accessibility to their special educational needs.

RESUMO

Exacerbação aguda de asma é uma condição frequente na criança e no adolescente e uma das causas mais comuns de procura aos pronto atendimentos e de internações. Pode ocorrer em pacientes que ainda não foram diagnosticados como asmáticos, e mesmo naqueles cujo controle da doença não se encontre adequado. Reconhecer a exacerbação e iniciar seu tratamento desde o domicílio até o adequado manejo inicial em ambiente hospitalar é fundamental para evitar sua evolução para complicações que coloquem o paciente em risco de vida. O tratamento compreende o reconhecimento e tratamento da hipoxemia, da obstrução e do processo inflamatório, além de fornecer orientações na alta hospitalar e encaminhamentos para continuidade do tratamento.


Acute exacerbation of asthma is a frequent condition in children and adolescents and one of the most common causes of seeking emergency care and hospitalization. It can occur in patients who have not yet been diagnosed with asthma, and even in those whose disease control is not adequate. Recognizing the exacerbation and starting its treatment from home until proper initial management in a hospital environment is essential to avoid its evolution to complications that put the patient at risk of life. Treatment comprises the recognition and treatment of hypoxemia, obstruction, and the inflammatory process, in addition to providing guidance at hospital discharge and referrals for continued treatment.

RESUMO

BACKGROUND & AIMS: Low bone mineral density (BMD) for age in people with Cystic Fibrosis (CF) is associated with worse nutritional status. The aim of this study is to assess body composition by anthropometry as a predictor of BMD in people with CF. METHODS: Multicenter cross-sectional study with 39 people aged 5 and 20 years with CF. BMD was assessed by dual energy x-ray emission (DXA) in the incidence of the total body less head (TBLH) and the TBLH Z-score (Z-TBLH) was calculated, adjusted by sex, age, height and ethnicity. Anthropometry was assessed by weight, height, mid-upper arm circumference (MUAC) and triceps skinfold (TSF). Arm muscle area (AMA) and Body Mass Index (BMI) were calculated. Lean mass (LM), fat mass (FM) and free-fat mass (FFM) were identified by DXA. The molecular analysis method by sequencing was used to identify and classify the participants regarding the presence of the F508del pathogenic variant of the CFTR gene. Statistical models of simple and multiple linear regression were created to establish the predictive power of Z-TBLH in the variables. RESULTS: Average age of the participants was 13.31 ± 3.86 years, 59% of whom were male. They showed more LM (30.97 Kg ± 11.29) than females (23 Kg ± 6.73). 20 of 30 participants (66.7%) had at least copy of F508del. Among the multiple models, adjusted by height, age and sex, it found BMI (R2 = 0.367), Weight (R2 = 0.220), AMA (R2 = 0.338) as significant predictors of Z-TBLH. The final model composed of AMA, TSF and Age (p = 0.001; R2 = 0.381) had AMA and Age as significant predictors. AMA was associated with an increase in the BMD Z-score in the participants studied. 66.7% of genetically tested participants had the F508del pathogenic variant. The presence of the F508del variant was associated with worse nutritional status. CONCLUSION: A statistical model composed of the values of AMA, TSF and Age can predict Z-TBLH, as well as anthropometric variables Weight, or BMI, or AMA associated with height, age and sex, in children and adolescents aged 5-20 years old, of both sexes. Anthropometric markers, as they are easy and relatively inexpensive to obtain, it is a promising alternative to the use of DXA in predicting BMD in these people with CF.

RESUMO

INTRODUCTION: Down syndrome individuals have different gait patterns, which include specific characteristics such as foot rotation asymmetryOBJECTIVE: The aim of this study was to analyze the relationship between this asymmetry and the hands-and-knees crawling pattern before gait acquisition in Down syndrome children, as well as the possible association of this gait to gender, ethnicity, comorbidities, physiotherapy, and occupational therapy interventionsMETHODS: In this cross-sectional study, 361 children with or without foot rotation asymmetry were selected. An online questionnaire was administered to the parents or guardians of those childrenRESULTS: Hands-and-knees crawling decreased the prevalence of foot rotation asymmetry in Down syndrome children. The longer it took for walking onset, the higher the prevalence of this asymmetry. Indeed, for each month of delay, there was a 7% increase in prevalence. There was a significant relationship between orthopedic alterations in knees or flat feet and foot rotation asymmetry. There was no significance related to gender, ethnicity, other comorbidities, physiotherapy, or occupational therapy interventionsCONCLUSION: The findings in this study revealed that foot rotation asymmetry might be related to the acquisition of motor skills, hands-and-knees crawling and the walking onset


INTRODUÇÃO: As pessoas com síndrome de Down (SD) apresentam diferentes padrões de marcha, incluindo algumas características específicas como a marcha de base alargadaOBJETIVO: O objetivo deste estudo foi analisar a relação entre a marcha de base alargada e a aquisição motora engatinhar em quatro apoios adquiridas antes da marcha em crianças com SD, bem como a provável associação desta marcha com gênero, etnia, comorbidades e tratamentos de fisioterapia e terapia ocupacionalMÉTODO: Neste estudo transversal, foram selecionados 361 indivíduos que apresentaram ou não marcha de base alargada. Um questionário on-line foi administrado para pais / responsáveis destas criançasRESULTADOS: O engatinhar em quatro apoios diminuiu a prevalência da marcha de base alargada em crianças com SD. Quanto maior o tempo em meses para os primeiros-passos, maior a prevalência de base alargada, sendo que, a cada mês de atraso, a prevalência aumenta em 7%. Foi observada significância entre as alterações ortopédicas em joelhos e pés planos e a marcha de base alargada. Não foi encontrada significância relacionada a gênero, etnia, outras comorbidades, fisioterapia ou terapia ocupacionalCONCLUSÃO: Os achados deste estudo mostraram que o aparecimento da base alargada pode estar relacionado às aquisições motoras, engatinhar em quatro apoios, e aos primeiros passos

RESUMO

OBJECTIVE: To measure peak inspiratory flow (PIF) and assess dynamic lung function in children and adolescents with asthma, as well as to determine the association of PIF with dynamic lung function and clinical variables. METHODS: This was a cross-sectional study of children and adolescents with asthma using dry powder inhalers (DPIs) regularly. The control group included sex-, age-, weight-, and height-matched individuals without lung disease. Socioeconomic and clinical variables were collected. PIF and dynamic lung function variables were obtained with a specific device. Between-group comparisons were made with the Student's t-test and ANOVA. Multiple linear regression analysis was performed, and Pearson's correlation coefficients were calculated to assess associations between PIF and the other variables. RESULTS: A total of 88 individuals (44 asthma patients and 44 controls) participated in the study. PIF and respiratory muscle strength (S-index) values were lower in the asthma patients than in the controls. PIF correlated positively with age, weight, height, and S-index in the asthma group. After controlling for height, we found an increase of 0.05 units in PIF associated with an increase of 1 unit in the S-index in the asthma group. CONCLUSIONS: PIF appears to be lower in children and adolescents with asthma than in those without asthma, correlating positively with age, height, weight, and respiratory muscle strength.

RESUMO

In this study, we analyzed the antioxidant activity and total phenolic content of the intertidal seaweed Palisada perforata collected from different reef microhabitats (sheltered site, tide pool, plateau, and exposed site) along the coast of Pernambuco (Brazil). Both parameters were compared with the same parameters of this species grown in the laboratory under two experiments simulating temperature, salinity, and desiccation conditions found in the reef. After both experiments (temperature x salinity and desiccation), the algal photosynthetic performance was measured through chlorophyll fluorescence parameters using a pulse-amplitude modulation fluorometer to test their stress response. Palisada perforata likely underwent stress by desiccation due to tidal fluctuations rather than to temperature or salinity changes. This conclusion agrees with our observations of the plateau site´s specimens, which were exposed to both air and UV radiation during low tides and exhibited higher antioxidant activity to avoid oxidative damage. However, despite the environmental stress, the antioxidant activity remained low, suggesting that photoinhibition is a crucial protection mechanism against oxidative damage.
