Association between intrinsic capacity and falls among older adults / 预防医学

Objective @#To examine the association between intrinsic capacity and falls in older adults, so as to provide insights into the risk assessment of falls. @*Methods@#Older adults aged 60 years and above were selected from two districts and one county in Bengbu City, Anhui Province from September 2022 to June 2023 using convenience sampling method. Demographic information, health-related behaviors and incidence of falls among participants were collected through questionnaire surveys. The intrinsic capacity included five dimensions: sensory, motor, vitality, cognition and psychology, which were investigated by the sensory dimension screening scale recommended by the World Health Organization, the Simple Physical Functioning Battery (SPPB), the Micro Nutritional Assessment Scale (MNAS-SF), the Brief Intelligent Mental State Examination Scale (MMSE), and the Center for Evaluation of Streamlined Depression Levels 10-entry scale (CESD-10), respectively. A total score of 1 or more indicated a decrease in intrinsic capacity. The association between intrinsic capacity and falls in older adults was analyzed by a multivariable logistic regression model.@*Results@#A total of 1 950 questionnaires were allocated, and 1 917 were valid, with an effective rate of 98.30%. There were 934 men (48.72%) and 983 women (51.28%), with a mean age of (68.15±3.42) years. There were 1 352 rural residents (70.53%) and 1 431 illiterate and primary school-educated residents (74.65%). In the past year, 347 residents fell, accounting for 18.10%. The median comprehensive score for intrinsic capacity was 1.00 (interquartile range, 2.00) points, and 1 320 had a decrease in intrinsic capacity, accounting for 68.86%. Multivariable logistic regression analysis showed that decline in intrinsic ability was associated with the risk of falls after adjustment for age, gender, educational level, marital status, alcohol consumption and self-rated health status (OR=1.531, 95%CI: 1.408-1.721).@*Conclusion@#Decreased intrinsic capacity in older adults may contribute to an increased risk of falls.

Design and Research of Wearable Fall Protection Device for the Elderly / 中国医疗器械杂志

A protective device was designed that can be worn on the elderly, which consists of protective airbag, control box and protective mechanism. The combined acceleration, combined angular velocity and human posture angle are selected as the parameters to determine the fall, and the threshold algorithm and SVM algorithm are used to detect the fall. The protective mechanism is an inflatable device based on CO2 compressed air cylinder, and the equal-width cam structure is applied to its transmission part to improve the puncture efficiency of the compressed gas cylinder. A fall experiment was designed to obtain the combined acceleration and angular velocity eigenvalues of fall actions (forward fall, backward fall and lateral fall) and daily activities (sitting-standing, walking, jogging and walking up and down stairs), showing that the specificity and sensitivity of the protection module reached 92.1% and 84.4% respectively, which verified the feasibility of the fall protection device.

Relationship among spontaneous turning direction, balance and fall risk in stroke patients during walking / 中国康复理论与实践

ObjectiveTo investigate the relationship among spontaneous turning direction, balance ability and fall risk in patients with stroke during walking. MethodsFrom December, 2021 to November, 2022, 94 patients with stroke were recruited from Beijing Bo'ai Hospital. They were assessed with simple Timed 'Up and Go' Test (TUGT, TUGT1), TUGT with a cup in hand (TUGT2), and TUGT with calculation task (TUGT3). The spontaneous turning directions at the turn point were recorded, and the patients were divided into no-same group (n = 34) and same group, and the same group was further divided into affected group (n = 33) and unaffected group (n = 27), according to the spontaneous turning direction. After a spontaneous turning of each TUGT, the patients were asked to finish another TUGT turning to the opposite direction. And then, they were assessed with single leg standing test, Functional Reach Test (FRT), 360° turning test and the Morse Fall Scale (MFS). ResultsThere were the most patients with left hemiplegia in the affected group (χ2 = 7.995, P < 0.05). The time of TUGT1, TUGT2 and TUGT3 was the most in the affected group and the least in the unaffected group (F > 4.009, P < 0.05), and it was more in the affected group than in the unaffected group as post-hoc test (P < 0.05). The one leg standing time (H = 9.403, P = 0.009) and FRT distance (F = 4.300, P = 0.016) were the least in the affected group and the most in the unaffected group, and it was less in the affected group than in the unaffected group as post-hoc test (P < 0.05). The turning time (F = 4.134, P = 0.019) and turning steps (F = 5.611, P = 0.003) were the most in the affected group and the least in the unaffected group, and it was more in the affected group than in the unaffected group as post-hoc test (P < 0.05). The score of MFS was the most in the affected group and the least in the unaffected group (H = 8.192, P = 0.017), and it was more in the affected group than in the unaffected group as post-hoc test (P < 0.05). ConclusionThe stroke patients spontaneously turning to the affected side during walking usually are poorer in balance function, and in a risk of fall.

Multiple resistance to primary pests of grain sorghum hybrids: Spodoptera frugiperda (Lepidoptera: Noctuidae), Diatraea saccharalis (Lepidoptera: Crambidae), and Diceraeus melacanthus (Hemiptera: Pentatomidae)

ABSTRACT Plant resistance is an important tactic within the precepts of Integrated Pest Management, and the existence of grain sorghum hybrids with multiple insect resistance could benefit crop management and sustainability. This study evaluated the susceptibility of 30 grain-sorghum hybrids to three major pests, namely, fall armyworm (FAW) Spodoptera frugiperda, sugarcane borer (SCB) Diatraea saccharalis, and green-belly stink bug (GBS) Diceraeus melacanthus. The hybrids were cultivated and experiments with each insect species were conducted separately in a greenhouse. For FAW, visual injury assessments were performed on plants 7 and 14 days after infestation (DAI). For SCB, insect presence and injury were assessed 40 DAI. For GBS, the plants were evaluated using a damage rating scale 12, 19, and 26 DAI. Cluster analysis allowed separating the grain sorghum hybrids into groups regarding the levels of resistance to each pest. Hybrid BRS373 stood out as moderately resistant to FAW; AG1090, 80G20, BRAVO, BRS373, AG1615, and IG220 were the most promising for SCB; and for GBS, hybrids 50A40, A9735R, JADE, ENFORCER, BUSTER, 50A10, and IG244 were the most nominated. This information will significantly aid sorghum breeding programs focused on developing commercial hybrids that comprise both insect-resistance and high-yield characteristics. However, further research should evaluate potential chemical and morphological plant traits underlying the lower levels of susceptibility to FAW, SCB, and GBS found in the selected sorghum hybrids.

Solutions of crude methanol extract and hexane and methanol fractions of C. proceraleaves were added at 1.15% and 2.14% concentrations to the artificial diet of S. frugiperda. The mortality and duration of larval and pupal phases, weights of female and male pupae, deformations of pupae and adults, the reduction of adults able to reproduce, pre-oviposition and oviposition periods, the number of postures per female, and the fecundity and fertility of S. frugiperdafemales were also evaluated. The extracts harmed the survival, development, and reproduction of S. frugiperda. The ingestion of extracts and fractions by caterpillars affected adults by decreasing the oviposition period, the number of postures, fecundity, and fertility. The crude MeOH extract at a2.14% concentration harmed the evaluated parameters of the insect, except for pupal mortality, female pupae weight, and pre-oviposition period. The MeOH fraction at 2.14% caused a 50.0% mortality of caterpillars and 16.0% deformation in pupae and 33.0% inadults, reducing by 72.0% the population able to reproduce. The MeOH fraction at the 2.14% concentration caused 25.0% and 38.0% of pupal mortality and deformation, respectively. Calotropis procerahas promising insecticidal properties for a biological insecticide, a convenient and sustainable strategy for protecting plants against S. frugiperda.

Teoria do risco de quedas em pessoas idosas na comunidade / Theory of the risk of falls in elderly people in the community

As taxas de quedas entre pessoas idosas na comunidade têm se mantido elevadas, apesar dos esforços em desenvolvimento de pesquisas que buscam explicar o fenômeno, descrever suas causas e consequências e maneiras de preveni-las. Pessoas com 60 anos ou mais sofrem o maior número de quedas fatais. Contudo, presume-se que existam mecanismos específicos sobre o risco de queda na população idosa que podem ser mais bem explorados por estudos empíricos e teóricos. Sendo assim, considera-se a relevância de se construir uma teoria de enfermagem capaz de agrupar elementos do fenômeno risco de quedas em pessoas idosas na comunidade, bem como descrever e predizer este fenômeno complexo e multifatorial. A presente pesquisa teve por objetivo construir uma teoria de enfermagem sobre o risco de quedas em pessoas idosas na comunidade. Trata-se de uma pesquisa do tipo teórico, orientada predominantemente pelo raciocínio indutivo, seguindo uma estratégia pesquisa-teoria. Utilizou-se o método geral para elaboração de teorias em disciplinas aplicadas de Swanson e Chermack, com desenvolvimento das fases de conceitualização e operacionalização. Associaram-se ao desenvolvimento das fases as etapas do método de pesquisa conceitual proposto por Meredith (1993), a partir de técnicas de estatística multivariada do tipo análise fatorial e estatística descritiva. Na fase de conceitualização, utilizou-se a etapa de descrição conceitual para obtenção de um modelo conceitual e, na fase de operacionalização, desenvolveram-se as etapas de indução conceitual e dedução conceitual para obtenção de uma estrutura conceitual. O processo de teorização permitiu identificar construtos que descrevem o risco de quedas em pessoas idosas na comunidade e estabelecer relações preditivas entre elementos associados ao risco de quedas dessas pessoas e a recomendação utilizada pela Organização Mundial da Saúde para os fatores de risco de quedas em pessoas idosas; elaborou nove proposições teóricas, capazes de predizer o fenômeno; estabeleceu 11 afirmativas axiomáticas que explicam o fenômeno a partir de um processo dedutivo e um guia prático para implementação do cuidado de enfermagem com base na operacionalização da teoria. Esta pesquisa desenvolveu uma teoria de médio alcance, que descreve e explica por meio de predições o fenômeno do risco de quedas de pessoas idosas na comunidade. A investigação contribui para o estudo da temática ao associar fatores de risco de quedas em pessoas idosas na comunidade como elementos de um possível diagnóstico de enfermagem que pode impactar o processo de cuidar do enfermeiro e o caráter metodológico de estratégia inovadora para elaboração de teorias de enfermagem.

Rates of falls among elderly people in the community have remained high, despite efforts in the development of research that seek to explain the phenomenon, describe its causes and consequences, and ways to prevent them. People aged 60 and over suffer the most fatal falls. However, we presume that there are specific mechanisms on the risk of falling in the elderly population that can be better explored by empirical and theoretical studies. Therefore, it is considered relevant to build a nursing theory capable of grouping elements of the risk of falls among elderly people in the community, as well as describing and predicting this complex and multifactorial phenomenon. This research aimed to build a nursing theory about the risk of falls in elderly people in the community. This is a theoretical research, guided predominantly by inductive reasoning, following a research-theory strategy. Swanson and Chermack's general method for developing theories in applied disciplines was used, with the development of conceptualization and operationalization phases. It was associated with the development of phases, the steps of the conceptual research method proposed by Meredith (1993), based on multivariate statistical techniques such as factorial analysis and descriptive statistics. In the conceptualization phase, the conceptual description phase was used to obtain a conceptual model. In the operationalization phase, the stages of conceptual induction and conceptual deduction were developed to obtain a conceptual structure. The theorization process allowed identifying constructs that describe the risk of falls for elderly people in the community, establishing predictive relationships between elements associated with the risk of falls for elderly people in the community and the recommendation used by the World Health Organization for risk factors for falls in elderly people; elaborated nine theoretical propositions, capable of predicting the phenomenon; eleven axiomatic statements that explain the phenomenon from a deductive process; and a practical guide for the implementation of nursing care based on the operationalization of the theory. This research developed a medium-range theory, which describes and explains through predictions the phenomenon of the risk of falls among elderly people in the community. It contributes by associating risk factors for falls in elderly people in the community as elements of a possible nursing diagnosis that may have future impacts on the nursing care process and on the methodological character of an innovative strategy for the elaboration of nursing theories.

Las tasas de caídas entre los ancianos de la comunidad se han mantenido elevadas, a pesar de los esfuerzos en el desarrollo de investigaciones que buscan explicar el fenómeno, describir sus causas y consecuencias, y formas de prevenirlas. Las personas de 60 años o más sufren las caídas más fatales. Sin embargo, se presume que existen mecanismos específicos sobre el riesgo de caídas en la población anciana que pueden ser mejor explorados por estudios empíricos y teóricos. Por lo tanto, se considera relevante construir una teoría de enfermería capaz de agrupar elementos del riesgo de caídas entre ancianos de la comunidad, así como describir y predecir este fenómeno complejo y multifactorial. Esta investigación tuvo como objetivo construir una teoría de enfermería sobre el riesgo de caídas en ancianos de la comunidad. Se trata de una investigación teórica, guiada predominantemente por el razonamiento inductivo, siguiendo una estrategia de investigación-teoría. Se utilizó el método general de desarrollo de teorías en disciplinas aplicadas de Swanson y Chermack, con el desarrollo de fases de conceptualización y operacionalización. Los pasos del método de investigación conceptual propuesto por Meredith (1993) estuvieron asociados al desarrollo de las fases, a partir de técnicas estadísticas multivariadas como el análisis factorial y la estadística descriptiva. En la fase de conceptualización se utilizó la fase de descripción conceptual para obtener un modelo conceptual y en la fase de operacionalización se desarrollaron las fases de inducción conceptual y deducción conceptual para obtener una estructura conceptual. El proceso de teorización permitió identificar constructos que describen el riesgo de caídas en ancianos de la comunidad y establecer relaciones predictivas entre elementos asociados al riesgo de caídas en estas personas y la recomendación utilizada por la Organización Mundial de la Salud para factores de riesgo de caídas en ancianos ; elaboró nueve proposiciones teóricas, capaces de predecir el fenómeno; estableció 11 enunciados axiomáticos que explican el fenómeno a partir de un proceso deductivo y una guía práctica para la implementación del cuidado de enfermería a partir de la operacionalización de la teoría. Esta investigación desarrolló una teoría de alcance medio, que describe y explica a través de predicciones el fenómeno del riesgo de caídas entre los ancianos de la comunidad. La investigación contribuye al estudio del tema al asociar factores de riesgo para caídas en ancianos de la comunidad como elementos de un posible diagnóstico de enfermería que pueda impactar en el proceso de atención de enfermería y el carácter metodológico de una estrategia innovadora para la elaboración de teorías de enfermería.

Objetivo: aplicar intervenções de enfermagem sobre prevenção de quedas a pessoas idosas com transtornos mentais. Material e Método: Trata-se de uma pesquisa- cuidado, para subsidiar a aplicação das intervenções de enfermagem foi utilizado componentes do Modelo Teórico de Promoção da Saúde, desenvolvido por Nola J. Pender. A primeira etapa do estudo foi desenvolvida em um Centro de Atenção Psicossocial e a segunda etapa no domicilio dos idosos. A coleta de dados foi realizada entre os meses de agosto a novembro de 2022, com idosos de idade igual ou superior a 60 anos, que estivessem sendo acompanhados no serviço. A amostra foi composta por 15 idosos. Para a coleta de dados, foi utilizado um formulário estruturado com variáveis sociodemográficas, investigação de saúde e doença e características do domicílio e um instrumento utilizado para avaliar o risco de quedas em idosos. A análise descritiva dos dados, ocorreu por meio do cálculo de frequências absolutas e relativas. Os aspectos éticos da resolução 466/12 foram respeitados em todas as fases do estudo. Resultados: Predominaram mulheres (80,00%), casadas (53,33%), com uma média de idade de 70,52 anos, de cor branca (53,33%) e analfabetos (55,33%). No que se refere às condições de saúde e doença, foi possível observar que o tipo de transtorno mental que mais predominou foi a depressão (60,00%) e a ansiedade (33,33%). Grande parte dos participantes do estudo (73,33%) relataram que já caíram ao menos 6 vezes, em um tempo médio de 1 ano. Ressalta-se que (93,33%) dos idosos não receberam orientações sobre prevenção de quedas no domicilio. Todos os idosos apresentaram alto risco de quedas. As intervenções de enfermagem foram realizadas aos idosos com transtornos mentais com alto risco para quedas. Considerações Finais: A maioria dos idosos tiveram quedas dentro do domicilio, a ocorrência de quedas nesse espaço está relacionada a insegurança do ambiente. Diante disso, a realização da intervenção foi de grande importância para a prevenção a quedas com enfoque na saúde do idoso direcionados aos gestores, profissionais e comunidade.

Objective: To apply nursing interventions on prevention of falls to elderly people with mental disorders. Material and Method: It is a research-care, to subsidise the application of nursing interventions was used components of the Theoretical Model of Health Promotion, developed by Nola J. Pender. The first stage of the study was developed at a Psychosocial Care Centre and the second stage in the home of the elderly. Data collection has been conducted between August and November 2022, with elderly people aged 60 and over, who were being accompanied in the service. The sample consisted of 15 elderly people. For the data collection, a structured form was used with sociodemographic variables, health and disease research and characteristics of the household, and an instrument used to assess the risk of falls in the elderly. Descriptive analysis of the data, occurred by calculating absolute and relative frequencies. The ethical aspects of resolution 466/12 were respected at all stages of the study. Results: Women predominated (80.00%), married (53.33%), with an average age of 70.52 years, white (53.33%) and illiterate (55.33%). With regard to health and illness conditions, it was observed that the type of mental disorder that predominated most was depression (60.00%) and anxiety (33.33%). A large number of the study's participants (73.33%) reported that they have already fallen at least 6 times, in an average time of 1 year. It should be noted that (93.33%) of the elderly did not receive guidelines on the prevention of falls in the home. All older adults were at high risk of falls. Nursing interventions were performed for elderly with mental disorders at high risk for falls. Final Considerations: Most of the elderly have had falls within the home, the occurrence of falls in this space is related to environmental insecurity. In view of this, the implementation of the intervention was of great importance for the prevention of falls with a focus on the health of the elderly directed towards managers, professionals and community.

Influencing factors of fall injury risks in manufacturing enterprises based on Bayesian networks / 环境与职业医学

Background Falls are one of the most important types of occupational injuries. The incidence of falls is high in manufacturing workers. However, most of the studies on falls in China focus on primary and secondary school students and the elderly, and there are few studies on falls in the occupational population. Objective To evaluate efficiency of Bayesian network model in predicting fall injury risks in manufacturing enterprise staff, and impacts from work content, work environment, enterprise status, and health management on falls and their mutual relationships, and provide a scientific basis for enterprises to carry out fall-associated injury intervention. Methods Data from the European Survey of Enterprises on New and Emerging Risks (ESENER) were used. The survey provided data on work content, working environment, enterprise status, and health management of enterprises in European countries. The outcome indicator, was fall injury risks reported in enterprises. A total of 23 potential impact factors covering work content, working environment, enterprise status, and health management were screened by least absolute shrinkage and selection operator (LASSO) regression, followed by Bayesian network model for structure learning and parameter learning and area under the curve (AUC) for model fitness evaluation, using R and Netica 5.18. Diagnostic inference analysis was also conducted to identify key influencing factors and key influencing chains of fall injury risks based on the change rate of fall injury risks. Results In 5997 enterprises surveyed, 2573 (42.9%) enterprises reported fall injury risks. Ordered by their coefficient estimates from high to low, the 14 variables (mean-squared error=0.20) selected by LASSO regression were: manual handling, repetitive arm movement, poor posture, using desktop computers, and using robots in the category of work content; abnormal temperature and noise in the category of working environment; company size and employee quality in the category of enterprise status; mental health training, regular risk assessment, availability of psychologists, health and safety procedures, and provision of psychological counseling in the category of health management. The fitting result of Bayesian network model for fall injury risks was good (AUC=0.779). The Bayesian network diagnostic inference identified five key influencing factors, including abnormal temperature (change rate=35.9%), poor posture (change rate=27.3%), noise (change rate=23.4%), manual handling (change rate=18.2%), and repetitive arm movement (change rate=5.1%). The key influencing chain was "manual handling - poor posture - repetitive arm movement - fall injury risks" (combined change rate=16.9%). Conclusion The Bayesian network model has a good predictive performance in predicting the risk of falls in manufacturing enterprises. Manufacturing enterprises need to focus on jobs involving manual handling and repetitive arm movement, identify and improve workers' poor posture and mental health problems, and avoid workers working in harsh temperature or noise environment.

Turn intention perception and fall detection for smart walkers / 中国康复理论与实践

ObjectiveTo improve the anti-fall capacity and safety of the smart walkers. MethodsTwo pressure sensors were placed on the handles on both sides of the walker. The confusion matrix was obtained, the corresponding operational intent labels were manually labeled, using a support vector machine (SVM) classifier for model prediction to predict the travel intent of the users. The user wore a gyroscope and the walker was equipped with a laser sensor, to measure the angular velocity, angular acceleration and the distance data, respectively, to detect the user's fall. ResultsThe classifier model established by SVM successfully predicted three operating states of the walker, namely straight ahead, left turning and right turning. The user's fall was detected by the sudden change of the following data: the combined angular velocity was greater than 100°/s, the combined angular acceleration was greater than 1.3 G, the angular acceleration of Z-axis was greater than 0.7 G or less than 0.2 G, and the distance was greater than 600 mm or less than 300 mm. ConclusionThe improvement of the walker can predict the turn intention of the user, and detect the user's fall.
