Poly(amidoamine)-type dendrimers (PAMAM) were synthesized by divergent routes, and generations (G0.5, G1.0, G1.5, G2.0 and G2.5) along with hydroxylated half-generation polymers (G0.5-OH, G1.5-OH and G2.5-OH) were characterized by Fourier-transform infrared spectroscopy, thermogravimetric analysis and differential scanning calorimetry. Carbon dioxide (CO2) capture tests were performed using thermogravimetric analysis. Among the absorption temperatures tested, 60 °C was the most promising: 0.77, 1.08, and 1.14 mol CO2 L 1 for G0.5-OH, G1.5-OH and G2.5-OH, respectively, of CO2 and partial pressure of 45 kPa. This showed that dendrimers with larger molecular structures have more hydroxyl groups and consequently capture more CO2. However, at low partial pressures (< 2 kPa), CO2 solubility in PAMAM increased with temperature reduction, confirmed by Henry’s solubility constant (398.4 mol m3 kPa 1, in G2.5-OH at 40 °C). According to the thermodynamic properties of CO2 solubilization, the process was spontaneous (∆Gsol < 0) and exothermic (∆Hsol < 0).

Abstract The present paper evaluated the potential application of the functionally graded material (FGM) concept to develop more durable concrete to carbonation, one of the main degradation mechanisms of reinforced concrete structures. Accelerated carbonation tests with controlled temperature (27 ( 2°C), CO2 concentration (3 ( 0.5%) and humidity (65 ( 5%) were carried out in homogeneous concretes and with functional gradation in which the porosity of the material was varied across the slices. For the manufacture of graded concrete specimens, concretes with water/cement ratios equal to 0.35, 0.45, and 0.55 were produced, with lower porosity (w/c = 0.35) close to the surface of the specimen. The advance of the carbonation front was evaluated after 8, 9, 10, 14, and 24 weeks of accelerated exposure, using the chemical indicator phenolphthalein. The results show that the functionally graded concrete had a carbonation coefficient (K) slightly higher than that of the concrete with a w/c ratio equal to 0.35 (1.71 and 1.54 mm.week-0.5, respectively) and much lower than concrete with water-cement ratio equal to 0.45 (2.31 mm.week-0.5) and 0.55 (3.78 mm.week-0.5). This demonstrates that functional grading can be an efficient method to increase the durability of concrete elements subject to carbonation.

Resumo O presente artigo avalia o potencial de aplicação do conceito de material com gradação funcional (MGF) ao desenvolvimento de concretos mais duráveis frente à carbonatação, um dos principais mecanismos de degradação das estruturas de concreto armado. Ensaios acelerados de carbonatação com temperatura (27 ( 2 °C), concentração de CO 2 (3 ( 0,5%) e umidade (65 ( 5%) controladas foram realizados em concretos homogêneos e com gradação funcional em que a porosidade do material foi variada ao longo dos corpos de prova. Para a confecção dos corpos de prova de concreto com gradação funcional foram utilizados concretos com relações água/cimento iguais a 0,35, 0,45 e 0,55 de forma que tivéssemos uma redução de porosidade à medida que nos aproximássemos da superfície da peça. O avanço da frente de carbonatação foi avaliado após 8, 9, 10, 14 e 24 semanas de exposição acelerada, empregando-se o indicador químico fenolftaleína. A partir dos resultados obtidos observou-se que os concretos com gradação funcional apresentaram coeficiente de carbonatação (K) ligeiramente superior ao do concreto com relação a/c igual a 0,35 (1,71 e 1,54 mm.semana -0,5 , respectivamente) e bastante inferior aos concretos com relação água cimento iguais a 0,45 (2,31 mm.semana -0,5 ) e 0,55 (3,78 mm.semana -0,5 ), evidenciando que a gradação funcional pode ser um método eficiente para proporcionar o aumento da durabilidade de elementos de concreto sujeitos à carbonatação.

Resumo: Introdução: A hipertensão arterial (HA) é a principal causa de morte por doenças cardiovasculares. Apesar dos avanços, o percentual de hipertensos não diagnosticados e não tratados é de 58,4%. A avaliação do dano cognitivo na hipertensão concentra-se na prevenção do acidente vascular cerebral, enquanto o dano funcional é ignorado. Esse manejo inadequado pode ser multifatorial. É objetivo fue analisar a opinião dos médicos sobre a relação entre hipertensão arterial e danos cognitivos. Metodologia: Estudo observacional, descritivo, transversal desenvolvido no período entre agosto de 2020 e agosto de 2023. Análise de dados obtidos a partir de questionário autoaplicável, anônimo e voluntário. Revelar informações sobre o perfil profissional, conhecimento sobre a HA, sua ligação com o comprometimento cognitivo (DC), diagnóstico e tratamento. Resultados: Foram incluídos 222 profissionais, 215 (96,8%) concordam com a existência de ligação entre hipertensão e outros fatores de risco cardiovascular na DC e 218 (98,1%) reconhecem ajudar pacientes com risco de sofrer de D.C. A avaliação da DC é realizada em casos selecionados por 132 (59,4%) participantes e 59 (26,7%) a fazem sempre. Dos que realizam avaliação, 103 (54%) utilizam o Mini Exame do Estado Mental (MEEM), 10 (5,2%) utilizam a Avaliação Cognitiva de Montreal (MoCA) e 9 (4,7%) utilizam o Clock Drawing Test. Em relação à diminuição da pressão arterial em pacientes idosos e a ligação com o risco de DC: 54 (24,3%) não reconhecem risco e 65 (29,2%) reconhecem risco moderado-alto. Em referência à implicação do tratamento de doenças cardiovasculares e DC: 217 (97,7%) reconheceram o efeito benéfico. Discussão: Dado o reconhecimento da ligação entre hipertensão e DC, seria de esperar que a DC fosse investigada na grande maioria, no entanto apenas 26,7% sempre a avaliam. Não há consenso sobre o método, sendo o MEEM o mais utilizado, com baixa aplicação do teste MoCA e/ou Clock Drawing Test, sendo estes últimos os que avaliam a função executiva, majoritariamente alterada nos DC vinculados à HA. Embora o tratamento das doenças cardiovasculares seja reconhecido como benéfico em relação à DC, o controle da HA em idosos é considerado arriscado. É feito um diagnóstico de uma situação em que é evidente uma disparidade entre o que se reconhece como saber e o que se afirma fazer. Conclusões: O papel da doença vascular no dano cerebral funcional é reconhecido, considerando-se necessário conhecer o estado cognitivo dos pacientes, porém há baixa aplicação de testes de triagem que avaliam a função executiva. Nesse contexto, evidencia-se uma lacuna entre o conhecimento e a prática médica.

Abstract: Introduction: High blood pressure (HBP) is the leading cause of death from cardiovascular disease. Despite the advances, the percentage of undiagnosed and untreated hypertensive patients is 58.4%. The evaluation of cognitive damage in HBP focuses on preventing stroke, while functional damage is ignored. This inadequate management may be multifactorial. The objective was to analyze the opinions that doctors have about the relationship between high blood pressure and cognitive damage. Methodology: Observational, descriptive, cross-sectional study developed in the period between August 2020 and August 2023. Analysis of data obtained from a self-administered, anonymous and voluntary questionnaire. Revealing information on the professional profile, knowledge of HBP, its link with cognitive impairment (CD), diagnosis and treatment. Results: 222 professionals were included, 215 (96.8%) agree with the existence of a link between HBP and other cardiovascular risk factors in CD, and 218 (98.1%) acknowledge assisting patients at risk of suffering from CD. The CD evaluation is carried out in selected cases by 132 (59.4%) participants and 59 (26.7%) always do it. Of those who perform evaluation, 103 (54%) use the Mini Mental State Examination (MMSE), 10 (5.2%) use the Montreal Cognitive Assessment (MoCA) and 9 (4.7%) use the Clock Drawing Test. Regarding the decrease in blood pressure in elderly patients and the link with risk of CD: 54 (24.3%) do not recognize risk and 65 (29.2%) recognize a moderate-high risk. In reference to the implication of the treatment of cardiovascular disease and CD: 217 (97.7%) recognized a beneficial effect. Discussion: Given the recognition of the link between HBP and CD, it would be expected that CD would be investigated in the vast majority, however only 26.7% always evaluate it. There is no consensus on the method, the MMSE being the most used, with a low application of the MoCA test and/or Clock Drawing Test, the latter being the ones that evaluate executive function, mostly altered in CD linked to HBP. Although the treatment of cardiovascular disease is recognized as beneficial with respect to CD, the control of HBP in older adults is considered risky. A diagnosis is made of a situation where a disparity is evident between what one recognizes as knowing and what one claims to do. Conclusions: The role of vascular disease in functional brain damage is recognized, considering it necessary to know the cognitive status of patients, however there is a low application of screening tests that evaluate executive function. In this context, a gap between medical knowledge and practice is shown.

ABSTRACT Sports detraining is an essential process to guarantee a smooth transition for former athletes from a prolonged period of sports life to a post-sports life. In this sense, the objective of the research was to determine the current state of the detraining process of former athletes in situations of physical-motor disability, in the province of El Oro. For the study, through simple random sampling, eight former athletes in situations of physical-motor disability were selected. Former athletes have an average experience in the sports field of 8.38 (± 4.92) years. There was also interaction with coaches, Physical Education teachers, doctors, psychologists, family members and managers. Surveys were administered to all participants in the study, and anthropometric, medical, laboratory and functional tests were administered only to former athletes. Among the results obtained, it was possible to identify that there are limitations to face detraining as a training, pedagogical and social process, that retired athletes do not have sufficient information about this process and have a lack of significant projects, which is why it is revealed the need to design a detraining process, tailored to their specific needs.

RESUMEN El desentrenamiento deportivo es un proceso esencial, para garantizar una transición fluida a los exdeportistas, de un periodo prolongado de vida deportiva a una vida posdeportiva. En este sentido, la investigación tuvo como objetivo determinar el estado actual que presenta el proceso de desentrenamiento de exdeportistas en situaciones de discapacidad físico-motora, en la provincia El Oro. Para el estudio, se seleccionaron, a través de un muestreo aleatorio simple, a ocho exdeportistas en situaciones de discapacidad físico-motora. Los exdeportistas tienen una experiencia promedio en el ámbito deportivo de 8.38 (± 4.92) años. También se interactuó con entrenadores, profesores de Educación Física, médicos, psicológicos, familiares y directivos. Se aplicaron encuestas a todos los participantes en el estudio, y solo a los exdeportistas pruebas antropométricas, médicas, de laboratorios y funcionales. Entre los resultados obtenidos, se pudo identificar que existen limitaciones para afrontar el desentrenamiento como un proceso formativo, pedagógico y social, que los deportistas retirados no cuentan con información suficiente sobre este proceso y tienen carencia de proyectos significativos, por lo que se revela la necesidad de diseñar un proceso de desentrenamiento, ajustado a sus necesidades específicas.

RESUMO O destreinamento esportivo é um processo essencial para garantir uma transição tranquila para ex-atletas de um período prolongado de vida esportiva para uma vida pós-esportiva. Nesse sentido, a pesquisa teve como objetivo determinar o estado atual do processo de destreinamento de ex-atletas em situações de deficiência físico-motora na província de El Oro. Para o estudo, foram selecionados oito ex-atletas com deficiências físico-motoras por meio de amostragem aleatória simples. Os ex-atletas têm uma média de 8,38 (± 4,92) anos de experiência em esportes. Também interagimos com treinadores, professores de educação física, médicos, psicólogos, familiares e gerentes. Foram aplicados questionários a todos os participantes do estudo, e testes antropométricos, médicos, laboratoriais e funcionais foram aplicados somente aos ex-atletas. Entre os resultados obtidos, foi possível identificar que há limitações em lidar com o destreinamento como processo formativo, pedagógico e social, que os atletas aposentados não têm informações suficientes sobre esse processo e que carecem de projetos significativos, revelando, assim, a necessidade de se desenhar um processo de destreinamento ajustado às suas necessidades específicas.

ABSTRACT Hop tests are frequently used as a method of functional evaluation in athletes with lower limb injuries. In addition to traditional hop tests, there is a current proposal to include vertical jump tests. They can be evaluated through laboratory tests (force platform) or field tests (smartphone application or clinical evaluation). The objective of this study is to describe two simple, reliable, and low-cost field tests that can be used in clinical practice, along with other tests, to help physiotherapists design a rehabilitation program or treatment progression.

RESUMEN Las pruebas de salto (PS) son utilizadas con frecuencia como método de evaluación funcional en deportistas con lesiones de miembros inferiores. Actualmente, además de las PS convencionales, se propone incorporar las PS vertical. Estas pueden evaluarse mediante pruebas de laboratorio (plataforma de salto) o pruebas de campo (aplicación en smartphone o evaluación clínica). El objetivo de este paso a paso es describir dos pruebas de campo sencillas, confiables y de bajo costo que se pueden utilizar en la práctica clínica, en conjunto con otras pruebas, para ayudar a los/as kinesiólogos/as a diseñar un programa de rehabilitación o progresión del tratamiento.

ABSTRACT Introduction: Cerebral palsy (CP) is the most common cause of spasticity in childhood. An alternative treatment is selective dorsal rhizotomy (SDR). The selection of candidates for this surgery requires a thorough evaluation, and rehabilitation is essential to achieve the best results. The aim of this study is to describe the physical therapy evaluation and treatment of a girl with CP who underwent RDS. Case presentation: A seven-year-old girl with CP underwent RDS as part of the management of spasticity in her lower limbs. The patient was evaluated before RDS and at six months. The degree of spasticity, range of motion, muscle length tests, bone alignment, strength, functional performance, and gait were recorded. The treatment included a post-surgical inpatient stage and an outpatient stage. Conclusion: The physical therapy evaluation and treatment of a girl with CP who underwent RDS were described. We observed decrease in spasticity, absence of pathological reflex activity, improvement in selective motor control, increase in range of motion, greater distal strength, and improvement in the score on the video-based gait analysis scale and functional mobility scale. The girl achieved standing on the fifth post-surgical day and showed an increase in distances covered.

RESUMEN Introducción: La parálisis cerebral (PC) es la causa más frecuente de espasticidad en la infancia. Una alternativa de tratamiento es la rizotomía dorsal selectiva (RDS). La selección de los candidatos para esta cirugía requiere una evaluación exhaustiva, y la rehabilitación es fundamental para lograr los mejores resultados. El objetivo de este estudio es describir la evaluación y el tratamiento kinésico motor de una niña con PC que fue sometida a una RDS. Presentación del caso: Una niña de siete años con PC fue sometida a una RDS como parte del manejo de la espasticidad en los miembros inferiores. Se describió la evaluación antes de la RDS y seis meses después de esta. Se registraron el grado de espasticidad, el rango articular, las pruebas de longitud muscular, la alineación ósea, la fuerza, el desempeño funcional y la marcha. El tratamiento consistió en una etapa de internación postquirúrgica y una etapa ambulatoria. Conclusión: Se describieron la evaluación y el tratamiento kinésico motor de una niña con PC sometida a una RDS. Observamos disminución de la espasticidad, ausencia de actividad refleja patológica, mejor control motor selectivo, aumento del rango articular, mayor fuerza distal y mejora en el puntaje en la escala de videoanálisis de la marcha y en la escala de movilidad funcional. La niña logró la bipedestación al quinto día postquirúrgico y aumentó las distancias recorridas.

SUMMARY OBJECTIVE: Knee osteoarthritis is a common and disabling disease. We aimed to examine the effect of low-level laser therapy in addition to routine physical therapy modalities (transcutaneous electrical stimulation, superficial heating modality of infrared, ultrasound, and exercise) on the functional status and pain in knee osteoarthritis. METHODS: Patients with knee osteoarthritis (n=71) who underwent physical therapy (transcutaneous electrical stimulation, infrared, ultrasound, exercise therapy, and low-level laser therapy) were retrospectively screened. Patients who received low-level laser therapy on acupuncture points, transcutaneous electrical stimulation, infrared, ultrasound, and exercise were included in the low-level laser therapy (+) (n=35), and patients who received only transcutaneous electrical stimulation, ultrasound, infrared, and exercise were included in the low-level laser therapy (–) group (n=36). The Visual Analog Scale for activity pain, Lysholm Knee Scoring Scale, and walking and stair climbing tests were used before and after treatment obtained from patient files. RESULTS: The post-treatment Visual Analog Scale activity score and walking and stair climbing test results were statistically significantly lower in the low-level laser therapy (+) group than in the low-level laser therapy (–) group. There was no significant difference in post-treatment Lysholm Knee Scoring Scale scores between the two groups. In both groups, the Visual Analog Scale activity, Lysholm Knee Scoring Scale, and walking and stair climbing test scores statistically significantly decreased after treatment. CONCLUSION: Knee osteoarthritis increases with aging and creates significant functional limitations. low-level laser therapy with routine physiotherapy contributed to the improvement in the pain and functional status of the patients with knee osteoarthritis. Low-level laser therapy can be recommended in osteoarthritis treatment guidelines with the support of further studies, which is an easy-to-apply, effective, and reliable method.

RESUMEN Introducción: Las pérdidas cognitivas se encuentran entre los eventos más prevalentes en la población anciana y pueden causar déficits funcionales. Entre las alternativas de prevención y tratamiento no farmacológico disponibles, el aumento de los niveles de condición física funcional se presenta como una estrategia importante que sugiere mejoras en la función física y cognitiva de los ancianos, desencadenada por la práctica de ejercicios. Objetivo: Determinar el poder predictivo de los indicadores de aptitud funcional y establecer sus puntos de corte como discriminadores del deterioro cognitivo en adultos mayores. Métodos: La muestra estuvo compuesta por 310 ancianos que respondieron un cuestionario que comprendía información sociodemográfica, hábitos de vida, hospitalización en los últimos 12 meses, presencia de comorbilidad y el Mini-Examen del Estado Mental. La condición física funcional se evaluó utilizando la fuerza de agarre manual (FAM) y las pruebas de sentarse y levantarse de una silla. Para identificar predictores de deterioro cognitivo, se adoptó el análisis de curvas Receiver Operating Characteristic (ROC), con intervalo de confianza del 95% (IC95%). Posteriormente se identificaron los puntos de corte con sus respectivas sensibilidades y especificidades. Los análisis se realizaron respetando el nivel de significancia del 5%. Resultados: Se observó que algunos indicadores de aptitud funcional mostraron un Área Bajo la Curva (ABC) significativa, y la prueba de sentarse y pararse (ABC=0,72; 95%IC: 0,64-0,77) mostró los mejores resultados. Los mejores puntos de corte para el test FAM y el sit-and-stand test fueron 18,8 kgf y 8 repeticiones, respectivamente. Conclusión: Los resultados del presente estudio permiten concluir que el test sit-to-stand es moderadamente eficiente para discriminar la presencia de deterioro cognitivo en adultos mayores.

ABSTRACT Introduction: Cognitive losses are among the most prevalent events in the elderly population and can cause functional deficits. Among the available non-drug prevention and treatment alternatives, the increase in functional fitness levels is presented as an important strategy suggesting improvements in the physical and cognitive function of the elderly triggered by exercise. Objective: To determine the predictive power of functional fitness indicators and establish their cutoff points as discriminators of cognitive impairment in the elderly. Methods: The sample comprised 310 elderly people who answered a questionnaire comprising sociodemographic information, lifestyle habits, hospitalization in the last 12 months, presence of comorbidity, and the Mini-Mental State Examination. Functional fitness was assessed using the Hand Grip Strength (HGS) and sitting and rising from a chair tests. To identify predictors of cognitive impairment, analysis of Receiver Operating Characteristic (ROC) curves was adopted, with a confidence interval of 95% (95%CI). Subsequently, the cut-off points with their respective sensitivities and specificities were identified. The analyses were performed respecting the significance level of 5%. Results: It was observed that some functional fitness indicators showed significant Area Under the Curve (AUC), and the sit-and-stand test (AUC=0.72; 95%CI: 0.64-0.77) showed the best results. The best cut-off points for the HGS and sit-and-stand tests were 18,8 kgf and eight repetitions, respectively. Conclusion: The results of the present study allow us to conclude that the sit-to-stand test is moderately efficient in discriminating the presence of cognitive impairment in the elderly.

RESUMO Introdução: As perdas cognitivas estão entre os eventos mais prevalentes na população idosa, podendo causar déficits funcionais. Dentre as alternativas de prevenção e tratamento não medicamentosos disponíveis, o aumento dos níveis de aptidão funcional apresenta-se como uma estratégia importante sugerindo melhorias na função física e na função cognitiva de idosos, desencadeadas através da prática de exercícios. Objetivo: Determinar o poder preditivo dos indicadores de aptidão funcional e estabelecer seus pontos de corte como discriminadores do comprometimento cognitivo em idosos. Métodos: A amostra compreendeu 310 idosos que responderam a um questionário composto por informações sociodemográficas, hábitos de vida, hospitalização nos últimos 12 meses, presença de comorbidade e o Mini-Exame do Estado Mental. A aptidão funcional foi avaliada por meio dos testes de Força de Preensão Manual (FPM) e o de sentar e levantar da cadeira. Para identificação dos preditores do comprometimento cognitivo, foi adotada a análise das curvas Receiver Operating Characteristic (ROC), com intervalo de confiança de 95% (IC95%). Posteriormente, identificaram-se os pontos de corte com as respectivas sensibilidades e especificidades. As análises foram efetuadas respeitando-se o nível de significância de 5%. Resultados: Observou-se que alguns indicadores de aptidão funcional apresentaram Área Sob a Curva (ASC) significativas, sendo que o teste de sentar e levantar da cadeira (ASC=0,72; IC95%= 0,64-0,77) apresentou os melhores resultados. Os melhores pontos de corte para o teste de FPM e o teste de sentar e levantar da cadeira foram de 18,8 kgf e 8 repetições respectivamente. Conclusão: Os resultados do presente estudo permitem concluir que o teste de sentar e levantar da cadeira apresenta moderada eficiência para discriminar a presença de comprometimento cognitivo em idosos.

There's limited evidence of the potential benefits of cardiopulmonary and metabolic rehabilitation (CPMR) in patients with heart failure with preserved ejection fraction (HFpEF) or mildly reduced ejection fraction (HFmrEF) and coronary artery disease (CAD). The aim of this study was to investigate the impact of CPMR on the myocardial ischemia response (MIR), exercise-induced arrhythmias (EIA), New York Heart Association (NYHA) functional class, heart rate recovery (HRR), Borg CR10 perceived symptoms, and the SF-36 physical and mental health summary scores. A prospective cohort study was conducted with 106 patients undergoing 12 weeks of CPMR who completed two exercise tests pre- and post-CPMR: 1) maximum incremental test (CPX) and 2) submaximal constant load test (SUB). After CPMR, the effects on MIR, EIA, NYHA functional class, and HRR during both tests were analyzed. There was a significant change in NYHA functional classes after CPMR, with 96% of the patients in class I (vs 62% pre-CPMR, P<0.0001), 4% in class II (vs 32%), and none in class III (vs 6%). There was a significant reduction in the frequency of EIA (P<0.05) and MIR (P<0.001) and a significantly improved performance on both CPX and SUB tests (P<0.0001). Lastly, there was significant progress in the recovery metrics like HRR (P<0.0001), the Borg CR10 (P<0.0001), and the SF-36 summary scores (P<0.0001). The CPMR resulted in a significant decrease in EIA, delayed ischemia threshold in CPX and SUB tests, increased functional capacity, and improved quality of life.

Abstract Introduction Advanced Glycation End-Products (AGEs) are a diverse group of highly reactive molecules that play a vital role in the development of neurodegenerative disorders, such as Parkinson's Disease (PD), leading to a decline in functional and cognitive capacity. The objective of this study was to assess the intake and quantification of AGEs in individuals with PD and to correlate them with their functional and cognitive abilities. Methods This was a cross-sectional study involving 20 PD patients and 20 non-PD individuals as the Control group (C). The autofluorescence reader was used to evaluate skin AGEs, while food recall was used to quantify AGEs consumed for three different days. The Montreal Cognitive Assessment, Short Physical Performance Battery, and handgrip tests were used. PD patients demonstrated greater impairment in functional capacity compared to the control group. Results Dominant Handgrip (p = 0.02) and motor performance, in the sit and stand test (p = 0.01) and Short Physical Performance Battery (SPPB) (p = 0.01) were inferior in PD patients than the control group. Although PD patients tended to consume less AGEs than the control group, AGE intake was negatively correlated with handgrip strength in individuals with PD (r = -0.59; p < 0.05). Conclusion PD patients had lower strength and functional capacity, suggesting that the effects of AGEs might be exacerbated during chronic diseases like Parkinson's.

Abstract Background Recently, a new heart failure (HF) classification was made considering the left ventricular ejection fraction (LVEF) phenotype. Comprehensive assessments of the groups are required to guide patient management. Objective To determine the differences in sociodemographic, clinical, functional aerobic capacity, and health-related quality of life (HRQOL) variables in patients with HF classified with different LVEFs and to explore the correlations between the variables. Methods This work is a cross-sectional descriptive and correlational study. Three groups of patients with HF (LVEF≥50%, LVEF<40%, and LVEF40-49%) were compared. Sociodemographic, clinical variables and functional aerobic capacity with Sit to Stand (STS), 6-minute walk test (6MWT), Duke Activity Status Index (DASI), Minnesota Living with HF Questionnaire (MLFHQ), and Patient Health Questionnaire 9 (PHQ-9) were considered. The Chi-square test, one-way analysis of variance (ANOVA) test, and Spearman's correlation were used for statistical analysis. The statistical significance level was set at 5%. Results A total of 209 patients were admitted with a diagnosis of HF, with a more significant number of men. Marital status was a predominantly stable union in the HF with preserved ejection fraction (HFpEF) and HF with mid-range ejection fraction (HFmrEF) groups. A sedentary lifestyle was lower in the HF with reduced ejection fraction (HFrEF) group 59 (84.3%), p-value = 0.033, and the angina pectoris was higher in the HFpEF 30 (42.9%). Systolic blood pressure at the end of the 6MWT evidenced a higher score in HFpEF 132.0±17.25 concerning HFrEF 128.0±16.57, p-value=0.043. The fat percentage was higher in HFpEF 30.20±8.80 regarding the HFmrEF group 26.51±7.60, p-value = 0.028. Conclusion There were significant differences according to the LVEF classification in marital status, angina symptoms, fat percentage, and blood pressure at rest.

Abstract Objective This study aimed to analyze the longitudinal bond strength of a universal adhesive and chemically characterize the dentin substrate under different acid etching protocols. Methodology Dentin samples were etched with polyacrylic acid 25% (PAA) for 10 seconds (n=3) and phosphoric acid 32% (PA) for 15 seconds (n=3) and analyzed by Fourier transform infrared spectroscopy – attenuated total reflectance (FTIR-ATR) before and after treatment. For collagen degradation, samples (n=12) were divided into 3 groups: PAA, PA, and Deionized water (control), and analyzed by the quantity of solubilized type I collagen C-terminal cross-linked telopeptides and solubilized C-terminal peptide in relation to total protein concentration (ICTPtp and CTXtp) and by their ultimate tensile strength (UTS). For the adhesive interface analysis, dentin samples (n=72) were divided into 3 groups: PAA, PA, and Self-etch (SE), and subdivided into 2 groups: 24 h (baseline) and 1 year. The following tests were performed: microtensile bond strength (μTBS) (n=48), scanning electron microscopy (SEM) (n=12), and nanoleakage (n=12). Results The FTIR of PAA showed lower reduction of the peaks in the phosphate group when compared to PA. For ICTPtp, PA showed a significantly higher value. For CTXtp, PA and PAA groups failed to statically differ from each other. UTS was significantly lower for PA. For μTBS, storage time significantly affected bond strength. The results were unaffected by the etching protocol. For SEM, after 1 year, PA had little evidence of degradation in the upper third of the adhesive interface in comparison to the other groups. Nanoleakage showed no considerable silver impregnation after 1 year in the SE group. Conclusion The use of PAA prior to a universal adhesive (when compared to PA) represents a less aggressive type of etching to dentin. However, self-etching still seems to be the best option for universal adhesive systems that have functional monomers in their composition. protocols 25 (PAA n=3 n3 n (n=3 32 (PA FTIRATR ATR (FTIR-ATR treatment n=12 n12 12 (n=12 control, control , (control) Cterminal C terminal crosslinked cross linked ICTPtp CTXtp UTS. .
