ABSTRACT

Objective@#To establish an ultra-sensitive, ultra-fast, visible detection method for Vibrio parahaemolyticus (VP) .@*Methods@#We established a new method for detecting the tdh and trh genes of VP using clustered regularly interspaced short palindromic repeats/CRISPR-associated protein 12a (CRISPR/Cas12a) combined with recombinase polymerase amplification and visual detection (CRISPR/Cas12a-VD).@*Results@#CRISPR/Cas12a-VD accurately detected target DNA at concentrations as low as 10 -18 M (single molecule detection) within 30 min without cross-reactivity against other bacteria. When detecting pure cultures of VP, the consistency of results reached 100% compared with real-time PCR. The method accurately analysed pure cultures and spiked shrimp samples at concentrations as low as 10 2 CFU/g.@*Conclusion@#The novel CRISPR/Cas12a-VD method for detecting VP performed better than traditional detection methods, such as real-time PCR, and has great potential for preventing the spread of pathogens.

ABSTRACT

Introducción: La transición al modelo biopsicosocial implica que las herramientas de evaluación se adapten a esta nueva visión de la salud. Las herramientas usadas en Chile para medir la funcionalidad en las actividades de la vida diaria instrumentales (AVDI) son las mismas desde los años 50, por lo que se requiere hacer una revisión de la literatura a fin de conocer nuevas metodologías de evaluación en la materia. Objetivo: Identificar las herramientas de evaluación en AVDI, qué ítems son considerados, metodología de puntuación (rangos, puntajes, categorización de resultados), tiempo y contexto de aplicación, creadores de las herramientas y propiedades psicométricas de los mismos. Diseño: Revisión sistemática. Fuentes de datos: PubMed, BIREME y Epistemonikos. Se realizaron tres búsquedas: dos el 2018 (marzo y septiembre) y una el 2020 (diciembre). Selección de estudios: Estudios observacionales (estudios de cohorte y estudios de corte transversal) y revisiones sistemáticas que contemplaron la valoración de AVDI en mayores de 18 años, en inglés o español, publicados desde 1998 y de libre acceso. Extracción de datos: Se realizó lectura de títulos y resúmenes como primer filtro, y posteriormente el texto completo. Una vez seleccionados los estudios que cumplen con los criterios de inclusión, se les aplicó la pauta "Strengthening The Reporting of Observational studies in Epidemiology (STROBE)" y la pauta "Critical Appraisal Skills Programme Spanish (CASPe)" para evaluar la calidad metodológica. Se estableció, a través de un consenso de las investigadoras, que cada estudio seleccionado debía cumplir con al menos 13 de los 22 ítems de la pauta STROBE. Resultados: De los 27.606 artículos encontrados, 15 cumplieron con los criterios de inclusión y el punto de corte establecido de la pauta. Sólo un artículo era en idioma español y 14 en inglés; y fueron publicados principalmente en EE.UU. y España. De los 20 instrumentos encontrados en los artículos seleccionados, el 60% corresponde a la "Escala Lawton y Brody", el 10% a la de "The Performance Assessment of Self-Care Skills (PASS)" y el porcentaje restante otras herramientas. Conclusiones: A nivel internacional se han creado nuevas herramientas de evaluación de AVDI en respuesta a necesidades locales, dificultando la posibilidad de ser generalizadas a otros contextos sin contar previamente con un proceso de validación transcultural y estadística que resguarde la confiabilidad de su aplicación y data. La "Escala de Lawton y Brody", pese a las limitaciones ni sesgos, sigue siendo un patrón de oro a nivel internacional.


Background: The transition to the biopsychosocial model implies that the assessment tools are adapted to this new vision of health. In Chile, the evaluations to measure functionality on Instrumental Activities of Daily Living (IADL), have been the same since the 1950s, so a review of the literature is required to know new evaluation tools in the matter. Aim: To identify the evaluation tools that exist to assess the functionality in AVDI, what items are considered, scoring methodology (rank, score, categorization of results), time and in which contexts they are applied, assessment creators and psychometric properties. Design: Systematic review. Data sources: PubMed, BIREME and Epistemonikos. Three searches were carried out: two in 2018 (March and September) and one in 2020 (December). Study selection: Observational studies (cohort studies and cross-sectional studies) and Systematic Reviews that contemplated the assessment of IADL in people over 18 years of age, in English or Spanish, published since 1998 and open access. Data extraction: Titles and abstracts were read as a first filter, followed by the full text. Once the studies that met the inclusion criteria had been selected, the "Strengthening The Reporting of Observational studies in Epidemiology (STROBE)" and "Critical Appraisal Skills Programme Spanish (CASPe)" guideline was applied to assess methodological quality. It was established, through a consensus of the researchers, that each selected study had to comply with at least 13 of the 22 items of STROBE guideline. Results: Of the 27.606 articles found, 15 met the inclusion criteria and the established cut-off point of the guideline. One article was written in Spanish and 14 in English, which were carried out mainly in the United States and Spain (3 out of 15 respectively). Of the 20 instruments found in the selected articles, 60% correspond to "Lawton & Brody Scale", 10% to "The Performance Assessment of Self-Care Skills (PASS)" and the remaining percentage other tools. Conclusions: At an international level, new IADL assessment tools have been created in response to local needs, making it difficult to generalize to other contexts without previously having a cross-cultural and statistical validation process that safeguards the reliability of its application and data. The "Lawton s Brody Scale", despite its limitations and biases, remains an international gold standard.

ABSTRACT

Este ensaio busca abordar as alterações causadas pela COVID-19 nas funções cardiorrespiratórias diárias das pessoas que contraíram a patologia e evidenciar a importância dos exercícios físicos antes e depois da contaminação pelo vírus. A infecção causada pelo novo coronavírus mostrou efeitos deletérios em funções cardiovasculares e pulmonares principalmente em pessoas que necessitaram de tratamento intensivo, podendo provocar déficits tanto na frequência cardíaca, quanto complicações no suprimento de oxigênio de outras estruturas, ao ser relacionada aos componentes moleculares do sistema cardiovascular. Ao afetar as funções de cunho cardiorrespiratório, percebe-se que a doença provoca alterações na funcionalidade das atividades diárias das pessoas acometidas com a COVID-19. A melhora da qualidade de vida através dos exercícios físicos já vem sendo evidenciada muito antes da pandemia, porém, neste momento notou-se uma necessidade de adaptação da maioria dos exercícios diante do isolamento social, para assim facilitar a manutenção do condicionamento físico


This essay seeks to address the changes caused by COVID-19 in the daily cardiorespiratory functions of people who contracted the pathology and to highlight the importance of physical exercises before and after contamination by the virus. The infection caused by the new coronavirus showed deleterious effects on cardiovascular and pulmonary functions, especially in people who needed intensive treatment, which can cause changes in both heart rate and complications in the oxygenation of other structures, when related to the molecular structures of the cardiovascular system. When affecting the cardiorespiratory functions, it is noticed that the disease causes a deficit in the functionality of the daily activities of people affected with COVID-19. The improvement in quality of life through physical exercises has already been evident long before the pandemic, however, at this moment there was a need to adapt most exercises in the face of social isolation, and thus facilitate the maintenance of physical conditioning

ABSTRACT

Abstract. Dementia is characterized by a decline in memory, language, problem-solving and in other cognitive domains that affect a person's ability to perform everyday activities and social functioning. It is consistently agreed that cognitive impairment is an important risk factor for developing functional disabilities in patients with dementia. Functional status can be conceptualized as the ability to perform self-care, self- maintenance and physical activity. A person with dementia usually requires help with more complex tasks, such as managing bills and finances, or simply maintaining a household. Good functional performance is fundamental for elderly people to maintain independency and avoid institutionalization. The purpose of this review is to describe functional changes in demented patients, evaluating the variability in subgroups of dementias.


Resumo. Demência é caracterizada por declínio na memória, linguagem, resolução de problemas e de outros domínios cognitivos que afetam a capacidade de realização de atividades cotidianas e atividades sociais. É consensual que o comprometimento cognitivo é um importante fator de risco para o desenvolvimento de incapacidades funcionais em pacientes com demência. O status funcional pode ser conceituado como a capacidade de realizar autocuidado, automanutenção e atividade física. Uma pessoa com demência geralmente requer ajuda para tarefas mais complexas, como gerenciar contas e finanças, ou simplesmente realizar atividades domésticas. Um bom desempenho funcional é fundamental para que os idosos mantenham a independência e evitem a institucionalização. O objetivo desta revisão é delinear alterações funcionais em pacientes com demência, valorizando os subgrupos variados de demências.

ABSTRACT

Abstract Introduction: Few activities of daily living (ADLs) in chronic obstructive pulmonary disease (COPD) are tolerated because they are associated with ventilatory and metabolic changes. Simply lifting the upper limb muscle requires changes, resulting in thoracic abdominal asynchrony, increased dyspnea, and can interfere with quality of life (QoL). Objective: to relate the muscle strength of the shoulder girdle, trunk and hand grip with the degree of dyspnea in ADLs and secondarily correlate them with QoL in individuals with chronic obstructive pulmonary disease. Materials and Methods: Nine male subjects with chronic obstructive pulmonary disease III and IV (COPDG) and nine healthy, sedentary male individuals - control group (CG) were evaluated. All patients underwent the following evaluations: Pulmonary function, muscle strength of shoulder girdle, trunk and hand grip, and questionnaires. Results: In the intergroup analysis found that the spirometric variables of the COPDG were significantly lower compared to the CG. Intragroup analysis for measures of muscle strength, found significant difference for shoulder girdle, trunk and hand grip between both groups (COPDG) with lower mean (CG). Only the shoulder girdle had a positive correlation with ADL's and QoL. Conclusion: COPDG individuals, in addition to having pulmonary compromise, showed a significant decrease in muscle strength of the shoulder girdle, trunk and hand grip when compared to the CG. Only the shoulder girdle strength was positively correlated with the level of dyspnea in ADL's in QoL. Thus, pulmonary rehabilitation is an important tool for strengthening these muscles, possibly providing a positive impact on the degree of dyspnea during ADLs and reflecting on QoL.


Resumo Introdução: As atividades da vida diária (AVD's) na doença pulmonar obstrutiva crônica(DPOC) são poucas toleradas pelo fato de estarem associadas a alterações ventilatórias e metabólicas. A simples elevação dos membros superiores altera o recrutamento muscular, resultando em assincronia toracoabdominal, aumento da dispneia, podendo interferir na sua qualidade de vida (QV). Objetivo: relacionar as forças musculares da cintura escapular(CE), tronco(T) e preensão palmar(PP) com os graus de dispneia nas AVD´s e secundariamente correlacioná-las com a QV em indivíduos com DPOC. Materiais e Métodos: Foram avaliados 09 indivíduos com DPOC (III e IV) do sexo masculino - grupo DPOC (GDPOC) e 09 indivíduos saudáveis sedentários - grupo controle (GC). Todos foram submetidos às seguintes avaliações: prova de função pulmonar, forças musculares da CE, T, PP e questionários. Resultados: Na análise intergrupos constatou que as variáveis espirométricas do GDPOC foram significativamente menores comparados aos do GC. Na análise intragrupo, para as medidas das forças musculares, observou-se diferença significativa para PP, T e CE entre ambos os grupos (GDPOC com média menor que GC). Somente na força da CE houve correlação positiva com as AVD´s e QQV. Conclusão: Concluímos que indivíduos do GDPOC possuem, além do comprometimento pulmonar, apresentam diminuição significativa da força muscular da CE, T e PP quando comparado ao GC. Somente na força da CE houve correlação positiva com os graus de dispneia nas AVD´s e na QV. Sendo assim, a reabilitação pulmonar é um importante instrumento para o fortalecimento dessa musculatura proporcionando possivelmente um impacto positivo nos graus de dispneia durante as AVD´s e refletindo na QV.

ABSTRACT

Propósito: Analizar propiedades funcionales y antropométricas de los PA, criterios de selección de diseño, procesos de confección y materiales de fabricación, para analizar las ventajas y/o desventajas que proporcionan y el impacto de esto sobre la CV, ya que los PA disponibles en el mercado no siempre se adaptan a requerimientos del individuo. Se demostrará a través de la presentación de un caso clínico con amputación transmetacarpiana izquierda, de 60 años sufrida el 24/11/2012. Metodología y Materiales: Mediciones antropométricas elementos termoplásticos y de descarte. Resultados: A partir del análisis de propiedades y características de los PA se podría establecer la forma en la cual éstos inciden en la CV de las personas en cuanto a confort, seguridad e independencia funcional, y a partir de ello conocer el grado de satisfacción del usuario respecto a su participación ocupacional en las AVD. Conclusiones: Respecto al desarrollo de PA, se están abriendo nuevas posibilidades para la mejora de la CV de la población en general. Si bien el avance tecnológico está orientado a potenciar la autonomía de los usuarios mediante nuevas y variadas estrategias se ha ido intensificando en campos como la rehabilitación y la antropometría, es necesario en más de una ocasión incorporar acciones que permitan al paciente mejorar su economía, funcionalidad, durabilidad y adecuación estética.


Purpose: Analyze SP functional and anthropometric properties, design selection criteria, preparation processes and manufacturing materials, to analyze the advantages and/or disadvantages that they have and their impact on the LQ, since the SP available in the market do not always adapt to the individual’s requirements. It will be demonstrated through the presentation of a clinical case with left transmetacarpal amputation, 60 years old, suffered on 11/24/2012. Methodology and Materials: anthropometric measures, thermoplastic and disposable items. Results: From the analysis of properties and characteristics of the SP it could be established the way in which they affect people’s LQ in terms of comfort, safety and functional independence, and considering this we can determine the degree of the user’s satisfaction regarding occupational participation in DLA. Conclusions: Regarding the SP development, new possibilities are appearing for the improvement of general population LQ. Even though the technological advance oriented to highlight the user’s autonomy through new and various strategies has been intensifying in some other fields like rehabilitation and anthropometry, it is necessary in more than one occasion to incorporate actions that allow the patient to enhance his functionality with economy criteria, functionality, durability and aesthetics as quality standards in design and construction.

ABSTRACT

CONTEXTUALIZAÇÃO: Pacientes com doença pulmonar obstrutiva crônica (DPOC) queixam-se de dispneia nas atividades de vida diária (AVD) com os membros superiores (MMSS). A hiperinsuflação dinâmica (HD) é um dos mecanismos ventilatórios que contribuem para a dispneia. Para minimizar a HD, propõe-se a utilização de sistemas de ventilação não-invasiva (VNI). OBJETIVOS: Verificar se existe HD e dispneia durante a realização de uma AVD com os MMSS com e sem o uso da VNI. MÉTODOS: Participaram 32 pacientes com DPOC de moderada a muito grave, com idades entre 54 a 87 anos (69,4±7,4). Os pacientes elevaram potes com pesos de 0,5 a 5 kg durante 5 minutos, iniciando a elevação a partir da cintura pélvica em direção a uma prateleira localizada acima da cabeça, com e sem o uso da VNI (BiPAP®; IPAP 10 cmH2O; EPAP 4 cmH2O). Foram avaliadas a capacidade inspiratória (CI) e a dispneia (Escala de Borg). A CI foi mensurada antes e após a simulação da AVD. Na análise dos dados foram utilizados o teste t de Student para amostras dependentes e o teste de Wilcoxon. RESULTADOS: Houve redução significativa da CI após a AVD com e sem VNI (p=0,01). A dispneia aumentou após a AVD com e sem a VNI, mas entre ambos os protocolos não houve diferença. CONCLUSÕES: A simulação da AVD com os MMSS resultou em aumento da HD e dispneia. A VNI ofertada com pressões preestabelecidas não foi suficiente para evitar a HD e a dispneia.


BACKGROUND: Patients with chronic obstructive pulmonary disease (COPD) complain of dyspnea on activities of daily living (ADLs) with the upper limbs. Dynamic hyperinflation (DH) is one of the ventilatory mechanisms that may contribute towards dyspnea. To minimize the DH it is indicated the use of noninvasive ventilation (NIV). OBJECTIVES: To verify whether there is DH and dyspnea during the performance of ADL with the upper limbs with and without the use of NIV. METHODS: 32 patients with moderate-to-severe COPD, aged 54 to 87 years (mean 69.4, SD 7.4) were evaluated. The subjects lift up containers weighing between 0.5 and 5.0 kg over a five-minute period, starting from the waist level and putting them onto a shelf located above head height, with and without the use of NIV (BiPAP®; IPAP 10cmH2O; EPAP 4 cmH2O). The inspiratory capacity (IC) and dyspnea (Borg scale) were evaluated on all the patients. The IC was measured before and after simulation of the ADL. In order to analyze the data, Student's t test for dependent samples and the Wilcoxon test were used. RESULTS: There were statistically significant reductions in IC after the ADL with and without NIV (p=0.01). The dyspnea increased after the ADL with and without the NIV, however between both interventional procedures protocols no between-group difference was observed. CONCLUSIONS: The simulation of an ADL with the upper limbs resulted in an increase in DH and dyspnea. The NIV supplied with pre-established pressure was not enough to prevent the DH and dyspnea.

ABSTRACT

O objetivo do presente trabalho foi determinar os graus de correlação entre a autonomia funcional para as atividades da vida diária (AVDs) ea qualidade de vida (QV) em idosos. As mulheres idosas 15 voluntários (idade = 67,39 ± 4,23 anos de idade; IMC = 28,91 ± 3,41 kg / m 2) foram incluídos no aquático programas de exercícios físicos para 4,87 ± 1,06 meses. Eles foram submetidos a um bateria de testes de autonomia funcional do protocolo GDLAM 5 e QV avaliação foi através de um questionário WHOQOL-Old. O nível de p <0,05 foi ajustado para significância estatística. Através da correlação de Pearson, verificou-se uma significativa eo coeficiente de correlação inversa (r) entre o teste de caminhada de 10 m (10 mW) e Facet2 (Fac2), índice de autonomia geral (AI) mais Fac2 (r = -0,581; p = 0,023), levantar de uma cadeira e movendo-se em torno da casa (RCMH), Fac4 (r = -0,543; p = 0,036), 10mW mais a qualidade de vida global (GQoL-Velho) (r = -0,532; p = 0,041), e RCMH e GQoL-velha (r = -0,597, p = 0,019). a correlação foi baixa em todos os demais testes e facetas. Estes resultados sugerem que o atividade física aquática pode aumentar os níveis de qualidade de vida, tanto quanto o desempenho em ADL das idosas.


The aim of the present research was to determine the degrees of correlation between functional autonomy for activities of daily living (ADL) and the quality of life (QoL) in elderly individuals. The 15 volunteer elderly women (age = 67.39 ± 4.23 years old; BMI = 28.91 ± 3.41 kg/m2) were enrolled in aquatic physical exercise programs for 4.87 ± 1.06 months. They were submitted to a battery of 5 GDLAM protocol functional autonomy tests and the QoL evaluation was by WHOQOL-Old questionnaire. A level of p < 0.05 was set for statistical significance. Using Pearson’s correlation, we found a significant and inverse correlation coefficient (r) between the 10 m walking test (10mW) and Facet2 (Fac2), general autonomy index (AI) plus Fac2 (r= -0.581; p=0.023), rising from a chair and moving around the house (RCMH) , Fac4 (r= -0.543; p=0.036), 10mW plus the global quality of life (GQoL-Old) (r= -0.532; p=0.041), and RCMH and GQoL-Old (r= -0.597; p=0.019). The correlation was low in every remaining tests and facets. These results suggest that the aquatic physical activity can increase the QoL levels as much as the performance on ADL of the elderly women.

ABSTRACT

BACKGROUND: The practice of physical activities has proved to be an efficient strategy in the improvement of independency and cognitive functions in the elderly with Alzheimer's disease (AD). OBJECTIVE: To evaluate the relation between the practice of physical activity, cognition and activities of daily living (ADL) of patients with AD. METHOD: The cognitive and physical aspects and ADL were evaluated of 37 elders (19 normal controls, 11 sedentary with AD and 7 active with AD). RESULTS: The variable that best predicts the cognitive state (MMSE) is the duration of disease for the AD sedentary group and Lawton's Scale for the AD active group. We observed a correlation between MMSE score and duration of disease in the sedentary group and between MMSE and ADL in the active group. CONCLUSION: Our study showed that physical and cognitive stimulation in patients with AD can contribute to decrease cognitive and functional decline.


FUNDAMENTO: A prática de atividade física tem se mostrado uma estratégia eficaz na melhora da independência e das funções cognitivas em idosos com doença de Alzheimer (DA). OBJETIVO: Avaliar a relação entre a prática de atividade física, a cognição e as atividades de vida diária (AVD) em pacientes com DA. MÉTODO: Foram avaliados os aspectos cognitivos, físicos e as AVD de 37 idosos (19 controles normais, 11 com DA sedentários e 7 com DA ativos). RESULTADOS: A variável que melhor prediz o estado cognitivo (MEEM) foi o tempo de doença para o grupo DA sedentários e a Escala de Lawton para o grupo DA ativo. Observou-se correlação entre MEEM e tempo de doença no grupo sedentário e MEEM e AVD no grupo ativo. CONCLUSÃO: O nosso estudo mostrou que a estimulação física e cognitiva em pacientes com DA pode contribuir na diminuição do declínio cognitivo e funcional.

ABSTRACT

OBJETIVOS: Comparar o desempenho de idosos com diferentes níveis de gravidade de demência em questionários de atividades básicas de vida diária (ABVDs) e atividades instrumentais de vida diária (AIVDs). Verificar se existe correlação entre os questionários de AIVDs aplicados. METODOLOGIA: Foram aleatorizados 90 idosos (75,46 ± 7,66 anos) atendidos no Centro de Referência do Idoso-MG, com diagnóstico clínico de demência (DSM-IV/APA) e classificados quanto ao nível de gravidade da demência (Clinical Dementia Rating). As ABVDs foram avaliadas pelo índice de Katz, e as AIVDs, pelo índice de Lawton-Brody e de Pfeffer. Os testes de Kruskal-Wallis e de Mann-Whitney foram utilizados para verificar o desempenho dos idosos nas ABVDs, e a correlação de Spearman, para investigar a relação entre os instrumentos de AIVDs (alfa< 0,05). RESULTADOS: Foram encontradas diferenças estatisticamente significativas entre o desempenho dos idosos com diferentes níveis de gravidade de demência avaliados pelos instrumentos de ABVDs e AIVDs (p< 0,001). Os questionários de AIVDs apresentaram correlação significativa na amostra total (p< 0,0001; r= -0,818), nos grupos com demência leve (p= 0,007; r= -0,530) e grave (p< 0,0001; r= -0,723). CONCLUSÃO: A gravidade do processo demencial interferiu no desempenho dos idosos nas atividades básicas e instrumentais de vida diária. As AIVDs foram mais comprometidas nos estágios iniciais das demências, e as ABVDs, nos estágios mais avançados. Os questionários de AIVDs utilizados, apesar de sua particularidade estrutural, parecem medir um construto comum. A variabilidade do quadro clínico nos indivíduos com demência moderada pode explicar a ausência de correlação dos questionários usados nesse grupo específico.


OBJECTIVE: To compare the performance of elderly people with different levels of severity of dementia using questionnaires on basic activities of daily living (BADLs) and instrumental activities of daily living (IADLs). Also, to verify whether there were any association between the IADL questionnaires applied. METHOD: Ninety elderly people, aged 75.46 ± 7.66 years with a clinical diagnosis of dementia (DSM-IV/APA) who were seen at the Minas Gerais Reference Center for the Elderly, were randomized selected and classified according to the level of severity of their dementia (Clinical Dementia Rating). Their BADLs were assessed using the Katz Index and their IADLs by the Lawton-Brody and Pfeffer indexes. The Kruskal-Wallis and Mann-Whitney tests were used in order to investigate the elderly people's performance regarding BADLs, while the Spearman correlation was used to investigate the relationships among the IADL (alpha< 0.05). RESULTS: Statistically significant differences in performance were found between the elderly people with different levels of severity of dementia, as assessed by the BADL and IADL questionnaires (p< 0.001). The IADL questionnaires presented significant correlation for the total sample (p< 0.0001; r = -0.818) as well as for the groups with mild dementia (p= 0.007; r = -0.530) and severe dementia (p< 0.0001; r = -0.723). CONCLUSION: The severity of the dementia process interfered with the elderly people's performance of the elderly in BADLs and IADLs. The IADLs were more affected in the early stages of dementia whereas the BADLs were more affected in the more advanced stages. Despite structural particularities, the IADL questionnaires utilized seemed to be measuring a common construct. The variability in the clinical condition of the individuals with moderate dementia may be an explanation for the lack of correlation between the questionnaires in this specific group.
