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.

Introduction: Injuries are a major global public health problem. There are very few community-based studies on childhood injury from India in this study, we identified the distribution and risk factors for fall-related child injuries in the Chengalpattu district, Tamil Nādu community. Methodology: A descriptive analysis was done among 710 children of age up to 14 years residing in the Kat-tankulathur region in Tamil Nādu. The appropriate number of samples were recruited using the cluster sam-pling method by dividing the subjects into separate clusters and from each cluster 40 samples were obtained. The information on fall-related injury was collected according to mechanism of ‘injury’ Results: The annual incidence of fall-related injuries was 9.1 %. About 72.3% of children had injuries at home and 36% of the persons had fractures in the upper limb. 42% of children had disability in their hands. The age, gender, education and type of family was significant to injury. Conclusion:Our study reported a higher incidence of Fall injuries in Tamil Nādu when compared other stud-ies done in India. Male children are the most common victims of injury and also identified homes, roads/streets as the most common places for the occurrences of fall injury in children.

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.

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.

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.

Objective To investigate the current situation and risk factors of falls in the rural community elderly aged 65 years and above in Chongqing City, and to provide references for developing preventive measures. Methods The multistage cluster random sampling method was used to select several rural communities in Chongqing City from September to December, 2019, and then the elderly aged 65 years and above who lived in the communities for one year were chosen to serve as the surveyed subjects. A self designed questionnaire (sociodemographic factors, exercise status, illness and medication status and fall to related information) was used to collect the data regarding falls occurring in the last year. The chi-square test and multi factor multi-variant logistic regression analysis were utilized to analyze the data, the used software was SPSS 25.0. Results A total of 801 rural community elderly people in Chongqing City were surveyed.The average age was (71.64±5.85) years old. 7.12% of elderly need cane or walker. 6.87% of them self-reported their health was poor. 42.57% of elderly seldom have the habit of exercise. The prevalence of heart disease, diabetes, osteoporosis, arthritis, cataract, deafness self-reported was 8.99%、8.11%、17.48%、25.97%、13.73% and 6.24% respectively. Totally 104 elderly people experienced 128 falls in the past 12 months, and the incidence rates of falls and falling times were 12.84% and 15.98% respectively.The multi-variant logistic regression analysis showed that poor heath status self-reported(OR=4.04,95% , CI:1.71-9.52), diabetes (OR=2.68,95% CI: 1.41-5.12), osteoporosis (OR=1.91 , 95% CI:1.16-3.15), arthritis (OR=2.60 , 95% CI:1.65-4.11) and non self-care(OR=2.44,95% CI:1.16-5.16) were the risk factors for falls in the rural community elderly. Conclusions The incidence rate of falls in the rural community elderly aged 65 years and above in Chongqing City was low.It is necessary to formulate comprehensive intervention measures for the risk factors of fall so as to reduce the incidence rate of falls in the elderly.

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.

This study evaluated the toxic effects of organic extracts of Calotropis proceraleaves on the survival, development, and reproduction of Spodoptera frugiperda. 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.

ObjectiveTo analyze the characteristics of hospitalized unintentional injuries and to provide evidence for formulating injury prevention and control strategies. MethodsDescriptive analysis was conducted on injury information of unintentional injury cases reported from 22 monitoring hospitals during 2017 to 2020 by injury surveillance system. The composition ratio index was used to analyze and explore the distribution(population, time and place)of injuries related to different causes. The disease burden was described by the length of hospital stay and hospitalization cost. ResultsA total of 32 716 hospitalized unintentional injury cases were reported from 22 monitoring hospitals. The male to female ratio was 1.18∶1. The majority of males were aged 15‒64 years and the majority of females were aged over 45 years. The top three causes of injuries were falls, traffic-related and blunt injury. Injuries occurred more frequently in July and August. 42.81% of the cases occurred at home. Fracture cases accounted for 75.79%. The median length of hospital stay was 10 days and the median cost was 15 431.50 yuan. The share of both falls and non-motor vehicle accidents increased year by year. ConclusionFalls among elderly people and road traffic injuries are the main causes of hospitalized unintentional injuries, and sharp or blunt instrument injuries are more severe in the male workforce. Considering high direct and indirect economic losses from injuries, steps should to be taken to improve injury surveillance system and to implement injury prevention and control strategies targeted on key groups and key injuries.

Objective@#To systematically evaluate the incidence of falls among empty nesters in China, so as to provide the evidence for preventing falls among empty nesters.@*Methods@#Publications pertaining to cross-sectional studies of falls among empty nesters in China were retrieved from international and national databases, including CNKI, Wanfang Data, VIP, Cochrane Library, Web of Science and PubMed from inception to August, 2022. Meta-analysis was performed using the software Stata 15.1, and the combined incidence and 95%CI of falls among empty nesters in China was analyzed. Sensitivity analysis was performed using the leave-one-out method to evaluate the stability of outcome indicators. In addition, the publication bias was evaluated using Funnel plot. @*Results@#Initially, 795 articles were screened in the literature, and 17 articles were finally included, covering 5 468 participants. Meta-analysis revealed that the incidence of falls among empty nesters in China was 23.0% (95%CI: 16.6%-29.5%). Subgroup analysis showed that the incidence of falls among empty nesters published from 2016 to 2022 was higher than that from 2008 to 2015 (20.4% vs. 17.3%; P<0.05). The incidence of falls among empty nesters in western regions was higher than that in eastern and central regions (27.4% vs. 15.9% and 15.0%; P<0.05). The incidence of falls among empty nesters in urban areas was higher than that in rural areas (20.8% vs. 9.9%; P<0.05). Sensitivity analysis showed that the study results were stable, and the funnel plot identified some publication bias. @*Conclusion@#The incidence of falls among empty nesters in China was 16.6% to 29.5%, and it is recommended to strengthen the assessment and prevention of risk factors of falls among empty nesters.

Objective To analyze the correlation between the prevalence of chronic non-communicable diseases (NCDs) and fall incidence among the elderly in urban and rural areas in Chongqing, and to provide evidence for targeted intervention. Methods In 2019, a questionnaire survey was conducted among the elderly aged 65 and over in four districts and counties using multistage stratified cluster random sampling. The difference of NCDs prevalence and fall incidence was compared by Chi-square test. The correlation between NCDs and fall incidence was analyzed by multivariate logistic regression. Results A total of 806 and 801 elderly people aged 65 and above in urban and rural areas,respectively, were investigated The fall incidence among the elderly in rural areas (12.98%) was higher than that in urban areas (7.94%) (χ2=10.916, P=0.001). The multivariable logistic regression analysis showed that the prevalence of heart disease (OR=2.988, 95%CI:1.544-5.785), osteoporosis (OR=2.696, 95%CI:1.527-4.760) and vestibular dysfunction or deafness (OR=3.180, 95%CI:1.142-8.861) was associated with fall incidence among urban elderly people. Factors including need for care (OR=2.315,95%CI:1.130-4.744), diabetes (OR=3.067,95%CI:1.634-5.756), osteoporosis (OR=1.972, 95%CI:1.210-3.214), and arthritis (OR=2.975, 95%CI:1.901-4.657) were associated with fall incidence among rural elderly people. Conclusion The fall incidence among the elderly in rural areas is higher than that in urban areas in Chongqing. The prevalence of NCD is high among the elderly. Timely treatment of NCDs should be provided to reduce fall incidence among the elderly.

Objective @#To investigate the characteristics of mortality of falls among the elderly in Haishu District, Ningbo City, Zhejiang Province, so as to provide insights into the improvement of fall control strategy. @*Methods@#Data pertaining to surveillance of falls in Haishu District from 2017 to 2022 were collected from the Ningbo Municipal Digital Disease Prevention and Control Platform. The trends in mortality of falls in Haishu District from 2017 to 2022 were evaluated using annual percent change (APC). The distribution of demographic characteristics, locations of falls, injury sites, interval from fall occurrence to death and type of falls specified by age were descriptively analyzed.@*Results@#A total of 1 206 deaths occurred due to falls among the elderly at ages of 60 years and older in Haishu District from 2017 to 2022, including 414 men and 612 women, with a male to female ratio of 0.67∶1. The average age was (85.20±8.42) years. The average annual crude mortality and standardized mortality of were 101.10/105 and 85.40/105 from 2017 to 2022, respectively, with no obvious changing trends (APC=5.797% and 5.337%, all P>0.05). The standardized death rate of falls in females was higher than that of males (102.60/105 vs. 69.55/105, P<0.05). The average annual mortality of falls appeared a tendency towards a rise with age among the elderly at ages of 60 years and older, with the highest mortality of 147.18/105 seen in the elderly at ages of 85 years and older. Falls predominantly occurred at home (836 cases, 81.48%) and on the same level (881 cases, 85.87%). The injury sites were mainly lower limbs (388 cases, 37.82%) and head (308 cases, 30.02%). In addition, the interval from fall occurrence to death mainly ranged from 24 hours to 6 months (757 cases, 73.79%). @*Conclusion@#The mortality of falls appeared a tendency towards a rise with age among the elderly at ages of 60 years and older in Haishu District from 2017 to 2022, which was higher in women than in men. The location of falls was predominantly at home and the type of falls predominantly at the same level. High attention to residential environments, and reinforcement of gender- and age-specific interventions are recommended.

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.

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.

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.

Resumo Objetivo investigar a associação dos biomarcadores inflamatórios na tarefa de ultrapassagem de obstáculos com diferentes níveis de complexidade manipulados pela característica do obstáculo (sólido e frágil) em idosos. Método 17 idosos (≥60 anos) foram avaliados em dois momentos: 1) Análise do padrão locomotor durante a ultrapassagem de obstáculo em duas condições (sólido e frágil). As variáveis estudadas, para membros de abordagem e suporte foram: velocidade, comprimento, largura e duração da passada, distância horizontal pé-obstáculo, distância horizontal obstáculo-pé, distância vertical pé-obstáculo e Máxima elevação do pé. 2) A análise dos biomarcadores interleucina 6 (IL-6) e proteína C Reativa (PCR) foi realizada por meio de coleta de sanguínea. A análise de regressão linear múltipla foi realizada para verificar associação entre o padrão locomotor e os biomarcadores inflamatórios (IL-6 e PCR) com nível de significância de p≤0,05. Resultados A análise de regressão mostrou que a Interleucina 6 apresentou associação com as seguintes variáveis: 1) largura da passada na condição obstáculo sólido, 2) máxima elevação do pé (membro de suporte) para ultrapassagem do obstáculo frágil, 3) distância horizontal pé-obstáculo (membro de abordagem) na condição de obstáculo sólido, 4) máxima elevação do pé (membro de abordagem) para ultrapassagem do obstáculo frágil, 5) máxima elevação do pé (membro de abordagem) para ultrapassagem do obstáculo sólido. A PCR apresentou associação com a variável Distância Horizontal Pé-Obstáculo (membro de abordagem) apenas para a condição de obstáculo frágil. Conclusão Os biomarcadores inflamatórios apresentam uma associação com o comportamento locomotor em idosos, independente da condição de fragilidade do obstáculo.

Abstract Objective to investigate the association of inflammatory biomarkers on the locomotor pattern during obstacle avoidance with different levels of complexity manipulated by the characteristic of the obstacle (solid and fragile) in older adults. Method 17 older adults (≥60 years old) were evaluated in two moments: 1) Analysis of the locomotor pattern during obstacle crossing in two conditions (solid and fragile). The variables studied for trailing and leading limbs were: speed, length, width and duration of the stride, horizontal foot-obstacle distance, horizontal obstacle-foot distance, vertical foot-obstacle distance and Maximum foot elevation. 2) Blood collection, for analysis of the inflammatory biomarkers Interleukin 6 (IL6) and C-Reactive Protein (CRP). Multiple linear regression analysis was performed to verify association between locomotor pattern and inflammatory biomarkers (IL6 and CRP) with a significance level of p≤0.05. Results The regression analysis showed that Interleukin 6 was associated with the following variables: 1) stride width in the solid obstacle condition, 2) maximum foot elevation (leading limb) to avoidance the fragile obstacle, 3) horizontal foot-obstacle distance (trailing limb) in solid obstacle condition, 4) maximum foot elevation (trailing limb) to avoidance the fragile obstacle, 5) maximum foot elevation (trailing limb) to avoidance the solid obstacle. C-Reactive Protein was associated with the horizontal foot-obstacle distance (trailing limb) only for the fragile obstacle condition. Conclusion Inflammatory biomarkers are associated with the locomotor pattern in older adults, regardless of the fragility of the obstacle.
