ABSTRACT
Reliable analytical methods are the basis for the elucidation of phenolic compounds in foods. This study aimed to optimize and validate a method for determining 42 phenolics using reverse-phase (RP) high-performance liquid chromatography (HPLC) coupled to diode-array-detector-DAD. The performance of two RP columns was evaluated. The 150x4.6 mm 3-µm column showed superior separation quality, whereas 35 of the 42 phenolics showed a separation resolution ≥1.5. The method's linearity, precision (coefficient variation< 3.09%), recovery (87.5-103.2%), specificity, limits of detection (0.04-0.25 mg/L), and quantification (0.06-0.25 mg/L) had acceptable ranges. Thirty phenolics were quantified in Citrus peels, mainly flavanones, flavanols, flavonols, and phenolic acids, highlighting the high values of hesperidin (535-35070 mg/kg) and naringin (26-36466 mg/kg). Lemon peels named 'Lisboa,' 'Thaiti,' 'Thaiti-2000', and 'Thaiti-2001' presented the main phenolics associated with antioxidant capacity. The presented method was robust for determining 42 phenolic compounds, offering a new approach for bioactive compound quantification in food matrices.

This study proposes a new efficient wireless biosensor based on magnetoelastic waves for antibody detection in human plasma, aiming at the serological diagnosis of COVID-19. The biosensor underwent functionalization with the N antigen - nucleocapsid phosphoprotein of the SARS-CoV-2 virus. Validation analyses by sodium dodecyl-sulfate polyacrylamide gel electrophoresis (SDS-PAGE), Western blotting (WB), atomic force microscopy (AFM), scanning electron microscopy (SEM), energy-dispersive X-ray (EDX) microanalysis and micro-Raman spectroscopy confirmed the selectivity and effective surface functionalization of the biosensor. The research successfully obtained, expressed and purified the recombinant antigen, while plasma samples from COVID-19 positive and negative patients were applied to test the performance of the biosensor. A performance comparison with the enzyme-linked immunosorbent assays (ELISA) method revealed equivalent diagnostic capacity. These results indicate the robustness of the biosensor in reliably differentiating between positive and negative samples, highlighting its potential as an efficient and low-cost tool for the serological diagnosis of COVID-19. In addition to being fast to execute and having the potential for automation in large-scale diagnostic studies, the biosensor fills a significant gap in existing SARS-CoV-2 detection approaches.

Abstract Objective: To revise the impact of telehealth on the quality of life, reduction in pulmonary exacerbations, number of days using antibiotics, adherence to treatment, pulmonary function, emergency visits, hospitalizations, and the nutritional status of individuals with asthma and cystic fibrosis. Data source: Four databases were used, MEDLINE, LILACS, Web of Science and Cochrane, as well as manual searches in English, Portuguese and Spanish. Randomized clinical trials, published between January 2010 and December 2020, with participants aged 0 to 20 years, were included. Data synthesis: Seventy-one records were identified after the removal of duplicates; however, twelve trials were eligible for synthesis. Included trials utilized: mobile phone applications (n=5), web platforms (n= 4), mobile telemedicine unit (n=1), software with an electronic record (n=1), remote spirometer (n=1), and active video games platform (n=1). Three trials used two tools, including telephone calls. Among the different types of interventions, improvement in adherence, quality of life, and physiologic variables were observed for mobile application interventions and game platforms compared to usual care. Visits to the emergency department, unscheduled medical appointments, and hospitalizations were not reduced. There was considerable heterogeneity among studies. Conclusions: The findings suggest that better control of symptoms, quality of life, and adherence to treatment can be attributed to the technological interventions used. Nevertheless, further research is needed to compare telehealth with face-to-face care and to indicate the most effective tools in the routine care of children with chronic lung diseases.

Três ensaios utilizaram duas ferramentas, incluindo chamadas telefônicas. Entre os diferentes tipos de intervenções, observou-se melhora na adesão, qualidade de vida e de variáveis fisiológicas para intervenções de aplicativos móveis e plataformas de jogos em comparação com os cuidados habituais. Visitas ao pronto-socorro, consultas médicas não agendadas e internações não foram reduzidas. Houve considerável heterogeneidade entre os estudos. Conclusões: Os achados sugerem que a melhora do controle dos sintomas, da qualidade de vida e da adesão ao tratamento podem ser atribuídos às intervenções tecnológicas utilizadas. No entanto, mais pesquisas são necessárias para comparar a telessaúde com o atendimento presencial e indicar as ferramentas mais efetivas na rotina de cuidados à população infantil com doenças crônicas pulmonares.
ABSTRACT
This systematic review aimed to assess the prevalence of temporomandibular disorders (TMD) in the Brazilian population, with studies that used the RDC/TMD or DC/TMD as diagnostic tools. A total of 6365 people from 11 studies were included. Sample mean age ranged from 12 to 69.5 years. The pooled prevalence of TMD was 33.6% (95% CI 31.5-35.8; I2 = 37.2). Prevalence of TMD was higher in females (37.0%) than in males (29.3%). Our results indicate that TMD is a prevalent condition across Brazil's territories. The results from this meta-analysis can help calculate more accurate sample sizes for future studies.
ABSTRACT
OBTECTIVES: Good communication is essential for resolving social conflicts, especially in closed communities such as prisons. When communication is interrupted by factors such as hearing loss or difficulties in coordination, voice, language, fluency, or disruption of any of the biological systems required to communicate, Human Communication Disorders can appear. This review aimed to identify the most prevalent communication disorders amongst prison inmates. MATERIAL AND METHOD: Systematic review through databases of studies that analyze individual inmates with communication disorders over the last 38 years. After reading the titles and abstracts and applying the eligibility criteria, 25 articles were selected and included in the final review. RESULTS: A sample of 2,188 individuals was evaluated, two studies were conducted with a female population only, while twelve studied exclusively males, and 11 articles had a mixed population. All the studies included evaluated language and communication disorders in general, with language impairment being more prevalent There are no English language studies evaluating language and communication disorders in incarcerated individuals from African countries, Latin America or Asia. DISCUSSION: Inmates have a high prevalence of language and communication disorders, and thus end up being more vulnerable within the prison system. Speech therapists are important members of the legal workforce and improve the health, well-being and participation of people in contact with or at risk of contact with the judicial system through the prevention, early detection, assessment and treatment of communication disorders.

Objetivos: La buena comunicación es fundamental para la resolución de los conflictos sociales, especialmente en una comunidad cerrada, como es el caso de las cárceles. Cuando la comunicación se interrumpe a causa de situaciones como pérdidas de audición o dificultades de coordinación, de voz, de lenguaje, de fluidez o la alteración de alguno de los diversos sistemas biológicos, la causa puede ser los denominados trastornos de la comunicación humana. Esta revisión tuvo como objetivo identificar los trastornos de comunicación más comunes entre personas privadas de libertad. Material y método: Revisión sistemática a través de bases de datos de aquellos estudios que analizan reclusos con trastornos de la comunicación en los últimos 38 años. Después de leer sus títulos y resúmenes y aplicar los criterios de elegibilidad, 25 artículos fueron seleccionados e incluidos en la revisión final. Resultados: Se evaluó una muestra de 2.188 individuos. Dos estudios se realizaron solo con poblaciones femeninas, mientras que 12 usaron muestras masculinas, y 11 artículos tuvieron una población mixta. Todos los estudios incluidos evaluaron los trastornos del lenguaje y la comunicación en general, siendo más frecuente las dificultades con el lenguaje. No hay estudios en inglés que evalúen los trastornos del lenguaje y la comunicación en personas encarceladas de países africanos, latinoamericanos o asiáticos. Discusión: Las personas privadas de libertad presentan una alta frecuencia de trastornos del lenguaje y la comunicación, por lo que terminan siendo más vulnerables dentro del sistema penitenciario. Los logopedas son miembros importantes del personal judicial, y mejoran la salud, el bienestar y la participación de las personas en contacto o en riesgo de contacto con el sistema judicial a través de la prevención, la detección temprana, la evaluación y el tratamiento de los trastornos de la comunicación.

ABSTRACT
BACKGROUND: The Japanese grape (Hovenia dulcis Thunberg) has potential as an antioxidant due to its high content of phenolic compounds in the early maturation stages. In this study, the antioxidant sodium erythorbate (CONTROL) was replaced by Japanese grape pseudofruits dehydrated by freeze-drying (FDP) and oven drying (OP), in Bologna sausages. The commercial natural antioxidant licresse (LS), based on licorice, has also been studied. RESULTS: No significant differences (P < 0.05) were observed for the proximate composition and the texture profile of the Bologna sausages. An increase in pH was observed during storage for all formulations. At 28 days, the treatments FDP and OP were darker (lower L* values) and less red (lower a* values), possibly due to the presence of tannins in these samples, which may have bound with the iron present in myoglobin and minimized the oxidation reactions. The use of different antioxidants affected the nitrite contents of the Bologna sausages during storage. Regarding the lipid oxidation, the Japanese grape powder was more effective in delaying the oxidation reactions in Bologna sausages after 14 and 21 days of storage when compared to LS and the CONTROL, respectively. CONCLUSION: The Japanese grape powders were effective in retarding the lipid oxidation of Bologna sausages, possibly due to the presence of bioactive compounds, such as phenolic compounds, tannins, and ascorbic acid, showing the potential of these pseudofruits as antioxidants for use in meat products. © 2022 Society of Chemical Industry.

PURPOSE: Investigate the effect of botulinum toxin type-A (BoNT-A) on spasticity and motor performance in children with Cerebral Palsy (CP) related to Congenital Zika Syndrome (CZS). METHODS: Prospective longitudinal observational study of 34 children with CP referred for BoNT-A treatment. Outcomes were evaluated with a muscle tone assessment scale (Modified Ashworth Scale - MAS) and the Patients' Global Impression of Improvement (PGI-I) scale. RESULTS: Mean age was 32.06 ± 3.07 months and 85% were classified as Gross Motor Function Classification System (GMFCS) V. Primitive reflexes were present in 56% of the sample. The majority of the parents (97.9%) reported improvement in range of motion or reduction in spasticity after treatment with botulinum toxin. No side effects were recorded. When compared to the baseline, median reduction in the MAS was 0.5 (IQR = 0). CONCLUSIONS: The findings of this study suggest that BoNT-A may effectively promote functional improvements and reduce muscle tone, improving the child's and family's quality of life.

INTRODUCTION AND OBJECTIVES: Studies assessing the effects of caffeine (CAF) on the cardiovascular system have demonstrated that CAF can delay cardiac recovery following exercise. This study intended to assess the impact of CAF intake before physical exercise on heart rate variability (HRV) and cardiovascular parameters. METHODS: This is a prospective, crossover, controlled clinical trial conducted at the University of Pernambuco, Petrolina, PE, Brazil. The experimental protocol was split into three stages with a minimum of 48 hours between them. Exercises intensity was standardized based on the one repetition maximum test (1RM), obtaining the load of each volunteer for the intensity of 75% of 1RM. In the second and third phases, the control protocols were applied and 300 mg caffeine was given 45 minutes before training. HRV indices were determined at the subsequent times: 0 to 5 minutes of rest (before) and during 30 minutes of recovery (Rec) (after exercise), divided into six intervals, each of 5 minutes. RESULTS: The final sample involved 30 volunteers. CAF delayed HRV recovery after resistance exercise. In general, CAF impaired recovery of HRV after resistance exercise. Significant changes were observed in the RMSSD, SDNN, TINN, SD1, low frequency and high frequency indices between the control and CAF group. CONCLUSION: CAF protocol delayed parasympathetic regulation of heart rhythm following exercise, slowing recovery of HR, blood pressure and HRV indices after exercise.

Introdução: Com a finalidade de evitar e reduzir lesões dos tecidos do canal do parto, a episiotomia pode ser realizada. Contudo, complicações cicatriciais podem ocorrer e resultar em desconfortos e dificuldades nas atividades diárias das parturientes. O uso de fotobiomodulação (FBM) em episiotomia é considerada uma alternativa de método não farmacológico para auxiliar no tratamento e cuidado destas puérperas. Objetivo: Revisar os estudos publicados nos últimos 20 anos sobre o efeito da FBM em episiotomia. Métodos: Revisão sistemática da literatura realizada através de busca digital em artigos publicados em revistas eletrônicas, ensaios clínicos e ensaios clínicos randomizados, entre os anos de 2000 e 2020, nas bases de dados eletrônicas PEDro, PubMed, Science Direct e Bireme. Resultados: Foram verificados estudos com aplicação da FBM para reparo tecidual e analgesia em episiotomia. A partir da análise de estudos metodologicamente mais robustos, a FBM não pareceu apresentar benefícios na aceleração do processo cicatricial, mas alguns resultados positivos para o controle da dor. Conclusão: De acordo com os achados, são necessários mais estudos com adequação de parâmetros e qualidade metodológica para elucidar quais os efeitos do uso da FBM no tratamento de episiotomia. (AU)
Introduction: To avoid and reduce lesions of tissues in the birth canal, an episiotomy can be performed. However, scar complications can occur and result in discomfort and difficulties in daily activities of parturient women. The use of photobiomodulation therapy (PBMT) in episiotomy is considered an alternative non-pharmacological method to assist in treatment and care of these puerperal women. Objective: To review the studies published in the last 20 years on the effect of PBMT on episiotomy. Methods: A systematic review was conducted through the search of articles published in electronic journals, clinical trials, and randomized clinical trials between 2000 and 2020, in the electronic databases PEDro, PubMed, Bireme, Science Direct. Results: Studies with the application of PBMT for tissue repair and analgesia in episiotomy were verified. From the analysis of methodologically robust studies, the PBMT did not represent benefits in accelerating the healing process, but some positive results for pain control. Conclusion: According to the findings, further studies are needed with adequate parameters and methodological quality to elucidate the effects of using PBMT in the treatment of episiotomy. (AU)

OBJECTIVE: The main aim of this study was to determine the impact of botulinum toxin A (BTX-A) on severity and frequency of drooling in children with Cerebral Palsy (CP) secondary to Congenital Zika Syndrome (CZS). METHODS: This is a prospective longitudinal observational study including 23 children who received bilateral injections of BTX in the parotid and submandibular glands. The Thomas-Stonell & Greenberg Drooling Severity and Frequency Scale was applied by a multidisciplinary team including Speech, Language and Hearing professionals. The Global Impression of Improvement (GII) Scale was also applied to assess parents' subjective perceptions of therapeutic response. Swallowing was assessed using Doppler ultrasonography. Univariate logistic regression was used to analyse differences between responders and non-responders. RESULTS: Participant age varied from 27 to 38 months (mean 31.78, SD = 2.61) all presented with Gross Motor Function Classification System (GMFCS) V. Drooling Severity and Frequency Scale scores ranged from 7 to 9 points (median = 9) prior to BTX administration and from 4 to 6 (median = 6) after. Pre- and post-treatment reduction in drooling severity occurred (Z = -3.746; p < 0.001). No cases of drooling worsening were reported. Only two subjects presented adverse effects attributed to BTX administration. Correlation was only confirmed with GII. DISCUSSION: This article presents the safe and positive impact of BTX-A administration guided by anatomical references described in the literature, even on children with microcephaly. Further studies are needed to facilitate the use of Doppler ultrasonography as a tool to characterize changes in sensory processing and motor response following intraoral input in children with CP.

OBJECTIVE: We assessed the acute effect of beetroot extract intake on cardiovascular and autonomic recovery subsequent to strength exercise. METHODS: This is a crossover, randomized, double-blind and placebo-controlled trial. We assessed 16 subjects but only 12 healthy male adults completed the two protocols in two randomized days: Beetroot extract (600 mg in capsule) and placebo (600 mg starch in capsule). Beetroot extract or placebo was ingested, the subjects endured 120 minutes seated at rest, followed by a 75% 1RM strength exercise and then remained seated for 60 minutes at rest. Cardiorespiratory parameters, heart rate (HR) variability (HRV) (SDNN, rMSSD, pNN50, SD1, SD2 HF [ms2]) were estimated before, during exercise and during recovery from exercise. RESULTS: ingestion of beetroot extract before exercise: accelerates the recovery of SBP following physical effort; improves HR recovery to baseline resting levels (beetroot protocol: change in â¼62% vs. placebo protocol: change in â¼80%), and intensifies the return of vagal HR control during recovery after exercise. CONCLUSIONS: Beetroot extract acutely improved cardiovascular and autonomic recovery after exercise.

BACKGROUND: Graded exercises tests are performed in adult populations; nonetheless, the use of this type of assessment is greatly understudied in overweight and obese adolescents. OBJECTIVE: To investigate heart rate autonomic responses to submaximal aerobic exercise in obese and overweight adolescents. METHODS: We recruited 40 adolescents divided into two groups: (1) overweight group comprising 10 boys and 10 girls between Z-score +1 and +2 and (2) obese group comprising 10 boys and 10 girls above Z-score >+2. Heart rate variability was analysed before (T1) and after exercise (T2-T4) on treadmill at a slope of 0%, with 70% of the maximal estimated heart rate (220 - age) for 20 minutes. RESULTS: Heart rate in the overweight group was: 93.2±10.52 bpm versus 120.8±13.49 bpm versus 94.6±11.65 bpm versus 93.0±9.23 bpm, and in the obese group was: 92.0±15.41 bpm versus 117.6±16.31 bpm versus 92.1±12.9 bpm versus 91.8±14.33 bpm. High frequency in the overweight group was: 640±633.1 ms2 versus 84±174.66 ms2 versus 603.5±655.31 ms2 versus 762.6±807.21 ms2, and in the obese group was: 628.4±779.81 ms2 versus 65.4±119.34 ms2 versus 506.2±482.70 ms2 versus 677.9±939.05 ms2; and root mean square of successive differences in the overweight group was: 37.9±18.81 ms versus 10.9±8.41 ms versus 32.8±24.07 ms versus 36.7±21.86 ms, and in the obese group was: 38.7±23.17 ms versus 11.5±8.62 ms versus 32.3±16.74 ms versus 37.3±24.21 ms. These values significantly changed during exercise compared with resting values in overweight and obese groups. Moreover, we also reported no significant difference of resting parasympathetic control of heart rate between obese and overweight adolescents. CONCLUSION: There was no significant difference of autonomic responses elicited by submaximal aerobic exercise between overweight and obese adolescents.

ABSTRACT Objective: The aim of this study was to evaluate the prevalence of Candida colonizationon oral cavity of pediatric individuals with acute lymphocytic leukemia (ALL) and its susceptibility/resistance to nystatin and amphotericin B. Methods: This was a cross sectional study with observational, descriptive and analytic approach. Saliva was collected from40 individuals diagnosed with ALL and from40 healthy subjects, as a comparative group, matched by age and gender with ALL group. The mean age for both groups were 8 years-old. The isolation and identification of the Candidaspecies were performed using the CHROMagarCandidaTM and confirmed by polymerase chain reaction. The samples were subjected to antifungal susceptibility by microdilution assay for nystatin and amphotericin B. Salivary alterations and chemotherapy-induced oralmucositis were evaluated using modifiedOral Assessment Guide. Results: The positivity to Candida was higher inALL individuals (32.5%,13/40)than in a comparative group(2.5%, 1/40) (p<0.001). Candida albicans was the most prevalent strain (86.6%). The mucositis was directly associated with positive Candidacolonization (p=0.017) in the ALL group but not related with salivary alterations (p= 0.479). Six strains of C. albicans (54.5%), on ALL group, were resistant to nystatin and all strains were not susceptible to amphotericin B. Conclusion: Candida colonization was associated with ALL condition and with oral mucositis in these individuals. C. albicans was the prevalent strain and most samples were resistant to antifungal agents tested, nystatin and amphotericin B.
RESUMO Objetivo: o objetivo deste estudo foi avaliar a prevalência e colonização de Candida na cavidade oral de indivíduos pediátricos com leucemia linfocítica aguda (LLA) e sua susceptibilidade/resistência à nistatina e à anfotericina B. Métodos: estudo transversal observacional com abordagem descritiva e analítica. A saliva foi coletada de 40 indivíduos diagnosticados com LLA e de 40 indivíduos saudáveis, como grupo comparativo, combinados por idade e sexo com o grupo LLA. A idade média para ambos os grupos foi de 8 anos de idade. O isolamento e a identificação das espécies de Candida foram realizados utilizando o CHROMagarCandidaTM e confirmados pela reação em cadeia da polimerase. As amostras foram submetidas a susceptibilidade antifúngica por meio de ensaio de microdiluição para nistatina e anfotericina B. As alterações salivares e a mucosite oral induzida por quimioterapia foram avaliadas utilizando o Guia de avaliação modificada. Resultados: A positividade para Candida foi superior aos indivíduos in situ (32,5%, 13/40) do que em um grupo comparativo (2,5%, 1/40) (p <0,001). Candida albicans foi a cepa mais prevalente (86,6%). A mucosite foi diretamente associada à colonização positive por Candida (p = 0,017) no grupo LLA, mas não relacionada com alterações salivares (p = 0,479). Seis estirpes de C. albicans (54,5%), no grupo LLA, eram resistentes à nistatina e todas as cepas não eram suscetíveis à anfotericina B. Conclusão: A colonização por Candida foi associada à condição LLA e à mucosite oral nesses indivíduos. C. albicans era a cepa predominante e a maioria das amostras eram resistentes aos agentes antifúngicos testados, nistatina e anfotericina B.
ABSTRACT
A ansiedade é caracterizada pelo sentimento de tensão, nervosismo, apreensão e preocupação que pode alterar a modulação do sistema nervoso autônomo sobre a condução elétrica ligada ao coração, determinando a intensidade nos batimentos cardíacos modificando a variabilidade da frequência cardíaca que é um importante indicador de condições normais e patológicas. Assim, o objetivo do estudo foi analisar a relação existente entre a ansiedade e o processo de regulação autonômica cardíaca. Este estudo trata-se de uma revisão integrativa desenvolvido por meio de buscas nas bases de dados da Lilacs, Medline e SciELO, com os descritores em ciências da saúde e operador booleano: ansiedade AND frequência cardíaca e, ansiedade AND sistema nervoso autônomo. A busca foi realizada durante o mês de setembro de 2017, sendo incluídos artigos disponíveis na íntegra; em português e inglês e; publicados nos últimos 06 anos. Excluiu-se artigos que não fossem originais, teses, dissertações e monografias. Obteve-se um total de 10 artigos, nos quais observou-se que a ansiedade altera a resposta autonômica, assim quando o corpo entra em tensão, aumenta-se a frequência cardíaca, o predomínio do sistema simpático e no relaxamento ocorre o domínio parassimpático. Assim indivíduos portadores de ansiedade apresentam menor variação na frequência cardíaca e possuem uma capacidade menor de interação social. Com isto, evidencia-se uma baixa adaptação do sistema nervoso autônomo em casos de ansiedade, sendo que a variabilidade da frequência cardíaca encontra-se reduzida; condição esta que pode ser classificada como patológica.
The anxiety is characterized by the sensation of tension, nervousness, apprehension and worry that can alter the modulation of autonomic nervous system on the electrical conduction linked to the heart, determining the intensity in the heart beats modifying the heart rate variability, which is an important indicator of conditions normal and pathological. Thus, the study objective is to analyze the relationship between anxiety and the process of autonomic cardiac regulation. This study is an integrative review developed through searches in the databases of Lilacs, Medline and SciELO, with the descriptors in health sciences and boolean operator: anxiety AND heart rate and anxiety AND autonomic nervous system. The search was performed during the month of September of 2017, being included articles available in full; in Portuguese and English and; published in the last 6 years. Was excluded articles that were not original, theses, dissertations and monographs. Was obtained a total of 10 articles, in which it was observed that anxiety alters the autonomic response, so when the body is in tension, increases your heart rate, the predominance of the sympathetic system and in the relaxation occurs the domain of the parasympathetic. Thus, individuals with anxiety present lower variation in heart rate and have a lower capacity for social interaction. With this, it is evident a low adaptation of the autonomic nervous system in cases of anxiety, being that the variability of the heart rate is reduced; condition that can be classified as pathological.
