ABSTRACT Grain production is steadily increasing; however, the static storage capacity remains inadequate in Brazil. The lack of proper facilities and the precarious and inadequate storage conditions lead to post-harvest losses due to factors interacting with the grains, causing their deterioration. Chemical treatments are commonly used to reverse these effects; however, their replacement with natural substances has been sought due to environmental and human health concerns. The objective of this review was to discuss a sustainable strategy for treating stored grains, focusing on the use of natural compounds with bioactive properties, such as antifungal, antioxidant, and insecticidal activities, with potential for further studies. Natural compounds with useful properties for application in grain storage were outlined. Research on the use of natural compounds in grain treatment is still in its early stages, requiring progress in identifying new promising compounds, understanding the mechanisms of action, and developing and optimizing effective extraction, application, and formulation processes to make the use of these substances viable. increasing however Brazil postharvest post harvest grains deterioration effects concerns antifungal antioxidant activities studies outlined stages action extraction viable

Resumen Introducción. El agroecosistema de café presenta gran importancia ambiental, social y económica en regiones subtropicales de México, pero también es vulnerable a eventos inesperados como el cambio climático. En la historia reciente, se ha documentado que el agroecosistema de café presenta un proceso constante de autoorganización basada en la adaptación y el aprendizaje ante los diversos escenarios adversos. Objetivo. Determinar la capacidad de resiliencia del agroecosistema cafetalero en la región centro del estado de Veracruz. Materiales y métodos. La investigación se realizó de diciembre de 2017 a noviembre de 2018 en Tezonapa, Veracruz, México. Se realizaron 52 entrevistas a caficultores para medir el índice de resiliencia, integrado por treinta variables, correspondientes a siete factores (social, económico, tecnológico, infraestructura, comunicaciones, institucional y ambiental). Estos factores fueron normalizados por el método de escalamiento mínimo-máximo. La resiliencia se estimó en una escala de 0-1, donde valores cercanos a cero representan baja capacidad de resiliencia y cercanos a uno, alta resiliencia. Los datos fueron analizados mediante estadística descriptiva y pruebas de Kruskal-Wallis y chi-cuadrado. Resultados. Se encontraron diferencias estadísticamente significativas (p<0,5) para los indicadores de las dimensiones económica (0,06) y tecnológica (0,22), con la menor contribución a la resiliencia. Por el contrario, las dimensiones sociales (0,78) y ambiental (0,74) tuvieron mayor contribución a la capacidad de resiliencia, determinado por el gradiente altitudinal. Conclusiones. Los indicadores con el mayor aporte a la capacidad de resiliencia del agroecosistema de café fueron los de dimensiones social y ambiental, y con bajo aporte las dimensiones económica y tecnológica.

Abstract Introduction. The coffee agroecosystems holds significant environmental, social, and economic importance in the subtropical regions of Mexico, but it is vulnerable to unexpected events such as climate change. In recent history, it has been documented that the coffee agroecosystem undergoes a constant process of self-organization based on adaptation and learning in the face of various adverse scenarios. Objective. To determine the resilience capacity of the coffee agroecosystem in the central region of the Veracruz state. Materials and methods. The research was conducted from December 2017 to November 2018 in Tezonapa, Veracruz, Mexico. Fifty-two interviews were conducted with coffee growers to measure the resilience index, which is composed of thirty variables corresponding to seven factors (social, economic, technological, infrastructure, communications, institutional, and environmental). These factors were normalized using the mim-max scaling method. Resilience was estimated on a scale of 0-1, where values close to zero represent low resilience capacity and values close to one, represent high resilience. The data were analyzed using descriptive statistics, Kruskal-Wallis tests, and Chi-squared tests. Results. Statistically significant differences (p<0,05) were found for the economic (0,06) and technological (0,22) dimensions indicators, which had the lowest contribution to resilience. Conversely, the social (0,78) and environmental (0,74) dimensions had a the highest contribution to resilience capacity, determined by the altitudinal gradient. Conclusion. The indicators that contributed the most to the resilience capacity of the coffee agroecosystem were those in the social and environmental dimensions, while the economic and technological dimensions contributed the least.

Summary: Currently, agricultural activity is constantly threatened by the effects of climate change and radical expression of environmental factors as irregular rainfall distribution responsible for water availability and deficit. These factors generate water stress in productive systems, whose negative effect is reflected on morphological, physiological and biochemical aspects of vegetative growth. The use of biostimulants arises as a strategy to counteract this impact, improving crop efficiency in the use of resources and generating responses, as metabolite production, among other substances that mitigate the effects of oxidative stress. In this context, waxes, hydrogen peroxide (H2O2), salicylic acid (SA) and ALGAENZIMSMR were used on raspberry plants subjected to moderate water stress (-0. 8 MPa) to evaluate the fruit response in aspects of vegetative growth, physiological and biochemical quality. For the establishment, a completely randomized design was used with 5 treatments: Green Cover as 5 mL L-1, H2O2 10-4 M, salicylic acid 0.27 mM, ALGAENZIMSMR 7.5 mL L-1 and the control with 50% recovery of the transpired volume as well as water potential similar to the rest of plants and 4 replicates. The results showed that waxes, SA and algal extract increased the photosynthetic rate; the four treatments increased root length; waxes increased root height; and H2O2 increased root biomass. Compared to the control, higher levels of vitamin C and anthocyanins were produced in fruits - a very important aspect due to the functionality of these compounds in human health. Therefore, the use of these biostimulants are a very useful tool for crop management in environments with water restriction.

Resumen: En la actualidad la actividad agrícola se ve amenazada constantemente por los efectos del cambio climático y la expresión radical de los factores ambientales, como la irregularidad en la distribución pluvial responsable de la disponibilidad del agua y déficit, que genera estrés hídrico en los sistemas productivos, cuyo efecto negativo se refleja en aspectos de crecimiento vegetativo, morfológicos, fisiológicos y bioquímicos. El uso de bioestimulantes surge como estrategia para contrarrestar este impacto, mejorando la eficiencia de los cultivos en el uso de los recursos y generar respuestas, como la producción de metabolitos entre otras sustancias, que mitigan los efectos del estrés oxidativo. Bajo este contexto se planteó el uso de ceras, peróxido de hidrogeno (H2O2), ácido salicílico (AS) y algaenzims, sobre plantas de frambuesa sometidas a estrés hídrico moderado (-0.8 MPa) con el objetivo de evaluar la respuesta en aspectos de crecimiento vegetativo, fisiológicos y calidad bioquímica de frutos, para el establecimiento se empleó un diseño completamente al azar con 5 tratamientos: greencover as® 5 mL L-1, H2O2 10-4 M, ácido salicílico 0.27 mM, algaenzims® 7.5 mL L-1 y el control con recuperación del 50% del volumen transpirado y con potencial hídrico similar al resto de plantas y 4 repeticiones. Como resultados se obtuvo que las ceras, AS y el extracto de algas incrementaron la tasa fotosintética, los cuatro tratamientos aumentaron la longitud de raíces, las ceras la altura, y el H2O2 la biomasa de raíz. Por otro lado, en comparación con el control, se produjeron mayores niveles de vitamina C y antocianinas en frutos, un aspecto muy importante por la funcionalidad de estos compuestos en la salud humana. Por lo tanto, el uso de estos bioestimulantes se puede visualizar como una herramienta de gran utilidad para el manejo de cultivos en ambientes con restricción de agua.

Abstract The organic composition of 65 °% of urban solid waste of the Metropolitan District of Quito originates from food waste, which has negative environmental effects. The purpose of this study was to evaluate the factors related to food waste in homes in the capital and characterize urban solid waste management. The study is quantitative and exploratory. An association analysis was performed for the main categorical variables through calculation of statistical chi squared and an assessment of polychoric relation. A descriptive and multi-scale statistical analyses were performed for focus of the social metabolism to characterize waste management. A noteworthy element was the relation between expenses for purchase of food and non-alcoholic beverages in the last month-household income in the last month (p value < 5 %). Between 2012-2021, the most representative median for waste generation corresponded to the Eugenio Espejo administration, with 141470 t/ year, with a metabolic waste rate of 2.45E-05 (t/year). On the other hand, the Tumbaco administration obtained 30217 t/year and 1.22E-05 t/year, respectively.

Resumo Nas últimas décadas, uma epidemia de doença renal crônica (DRC) tem sido associada a fatores ambientais e ocupacionais (estresse térmico decorrente de cargas de trabalho elevadas em altas temperaturas e exposição a produtos químicos, como agrotóxicos e metais), denominada DRC de origem não tradicional (DRCnt). Esta revisão descritiva tem como objetivo apresentar evidências recentes sobre estresse térmico, agrotóxicos e metais como possíveis causas de DRCnt e fornecer uma visão geral das estratégias brasileiras de regulamentação, fiscalização e vigilância sanitária relacionadas. Os trabalhadores brasileiros são comumente expostos a condições extremas de calor e outros fatores de risco de DRCnt, incluindo o aumento da exposição a agrotóxicos e metais. Além disso, há uma falta de regulamentação e fiscalização, políticas públicas e estratégias adequadas para proteger a saúde renal dos trabalhadores em relação aos principais fatores de risco. É provável que a DRCnt seja uma causa significativa de DRC no Brasil, uma vez que a etiologia da doença é desconhecida em muitos pacientes e diversas condições para seu desenvolvimento estão presentes no país. Estudos epidemiológicos devem ser realizados para explorar associações causais e estimar o impacto do calor, dos agrotóxicos e dos metais na DRCnt no Brasil. Além disso, as políticas públicas devem priorizar a redução da exposição dos trabalhadores e a promoção de sua saúde e segurança. décadas (DRC químicos metais, , metais) DRCnt. .

Abstract In the past decades, an epidemic of chronic kidney disease (CKD) has been associated with environmental and occupational factors (heat stress from high workloads in hot temperatures and exposure to chemicals, such as pesticides and metals), which has been termed CKD of non-traditional origin (CKDnt). This descriptive review aims to present recent evidence about heat stress, pesticides, and metals as possible causes of CKDnt and provide an overview of the related Brazilian regulation, enforcement, and health surveillance strategies. Brazilian workers are commonly exposed to extreme heat conditions and other CKDnt risk factors, including increasing exposure to pesticides and metals. Furthermore, there is a lack of adequate regulation (and enforcement), public policies, and strategies to protect the kidney health of workers, considering the main risk factors. CKDnt is likely to be a significant cause of CKD in Brazil, since CKD’s etiology is unknown in many patients and several conditions for its development are present in the country. Further epidemiological studies may be conducted to explore causal associations and estimate the impact of heat, pesticides, and metals on CKDnt in Brazil. Moreover, public policies should prioritize reducing workers´ exposure and promoting their health and safety. decades (CKD chemicals metals, , metals) nontraditional non traditional CKDnt. .

Abstract In areas with arid and semi-arid climates, the availability and quality of water are critical factors for the development of agronomy. To face the challenge, an alternative for the use of this resource is the implementation of efficient and sustainable techniques such as the use of drip irrigation. The objective of the work was to analyze the agronomic behavior of rye under unfavorable water and temperature conditions to determine the effectiveness of phenotypic stability on La Costa de Hermosillo, Sonora, Mexico. Two rye genotypes were planted under a split plot experimental design (large plot: three water levels and small plot: two genotypes of seeds obtained in different cycles). The agronomic characteristics of the plant, the physicochemical characteristics of the grain were evaluated; and the significance between the different variables was determined with a correlation analysis. The analysis of variance revealed effects on plant height, number of spikes and grains, grain size, thousand grain weight, yield and protein content of rye due to the different water regimes used. Between 219-314 spikes per linear meter were obtained, with a commercially acceptable grain size (7.45-7.95 mm long x 2.18-2.40 mm wide). High yield values (1.72-3.11 t ha-1) were also observed, as well as excellent protein content (20.3-22.8%). These results demonstrate that rye is a versatile cereal that adapts to adverse environmental conditions such as a decrease in the amount of irrigation water and extremely high temperatures.

Resumen En zonas de clima árido y semiárido, la disponibilidad y la calidad del agua son factores críticos para el desarrollo de la agronomía. Para enfrentar el desafío, una alternativa para el aprovechamiento de este recurso es la implementación de técnicas eficientes y sostenibles como el uso de riego por goteo. El objetivo del trabajo fue analizar el comportamiento agronómico del centeno en condiciones desfavorables de agua y temperatura para determinar la efectividad de la estabilidad fenotípica en la Costa de Hermosillo, Sonora, México. Se sembraron dos genotipos de centeno bajo un diseño experimental de parcelas divididas (parcela grande: tres niveles de agua y parcela chica: dos genotipos de semillas obtenidas en ciclos diferentes). Se evaluaron las características agronómicas de la planta, las características fisicoquímicas del grano; y se determinó la significancia entre las distintas variables con un análisis de correlación. El análisis de varianza reveló efectos sobre la altura de la planta, el número de espigas y de granos, tamaño de grano, el peso de mil granos, rendimiento y contenido de proteína del centeno debido a los diferentes regímenes hídricos utilizados. Se obtuvieron entre 219-314 espigas por metro lineal, con tamaño de grano comercialmente aceptable (7.45-7.95 mm largo x 2.18-2.40 mm ancho). También se observaron valores de rendimiento altos (1.72-3.11 t ha-1), así como un excelente contenido de proteína (20.3-22.8%). Estos resultados demuestran que el centeno es un cereal versátil que se adapta a condiciones ambientales adversas como disminución en la cantidad de agua de riego y temperaturas extremadamente altas.

Abstract The city of Parras de la Fuente, Coahuila is characterized by having criollo avocado trees with different morphological properties. However, very little information is available on their fruit nutritional and sensory characteristics. The objective of this work was to perform the bromatological, mineral, phytochemical and sensory characterization of 7 avocado landraces. The proximal analysis was carried out using standardized tests by the AOAC (2019), while the phytochemical content was determined using HPLC/MS equipment. Subsequently, the samples were evaluated using a hedonic test. The bromatological analysis showed significant differences in the total of the samples for the different response variables, which indicates the great genetic diversity among the sampled trees. The mineral that were determined in the highest concentration were Potassium, Magnesium and Calcium. Thirty-eight different phytochemical compounds were identified in the fruits, with a greater presence of flavones. While the sensory analysis showed a significant difference among the avocado landraces for the evaluated attributes. The flavor and texture attributes were the most important for the consumer preference. Different environmental factors (soil, climate, altitude, latitude, maturity) modify the nutritional composition of the avocado and its organoleptic characteristics. The results of this work may help propagation, fruit diversification and development of companies focused on this fruit in Parras de la Fuente, Coahuila.

Resumen La ciudad de Parras de la Fuente, Coahuila, se caracteriza por tener árboles de aguacate criollo con diferentes propiedades morfológicas. Sin embargo, es muy poca la información que se tiene sobre las características nutrimentales y sensoriales de los frutos de estos árboles. El objetivo del presente trabajo fue caracterizar bromatológica, mineral, fitoquímica y sensorial 7 aguacates criollos, obtenidos de diferentes árboles. El análisis proximal se realizó mediante pruebas estandarizadas por la AOAC (2019), mientras que el contenido de fitoquímicos se determinó en un equipo HPLC/MS. Posteriormente, las muestras se evaluaron mediante una prueba hedónica. El análisis bromatológico arrojó diferencias significativas en el total de las muestras para las diferentes variables de respuesta, lo que indica la gran diversidad genética entre los árboles muestreados. Los minerales que se determinaron en mayor concentración fueron Potasio, Magnesio y Calcio. Se identificaron 38 compuestos fitoquímicos diferentes en los frutos, con mayor presencia de flavonas, mientras que el análisis sensorial arrojó una diferencia significativa entre los criollos en las variables evaluadas. Los atributos de sabor y textura resultaron los más importantes para la preferencia del consumidor. Diferentes factores ambientales (suelo, clima, altitud, latitud, madurez) modifican la composición nutrimental del aguacate y sus características organolépticas. Los resultados de este trabajo pudieran ayudar a la propagación, diversificación frutícola y desarrollo de empresas enfocadas en este fruto en Parras de la Fuente, Coahuila.

RESUMO Este artigo analisa a implementação da Lei Florestal na província de Formosa que, ao contrário de outras províncias, concedeu à maioria das suas florestas nativas a categoria de proteção mais baixa da lei. Utilizando uma metodologia qualitativa, este trabalho reconstrói o processo de desenho e sanção do ordenamento de florestas nativas na província de Formosa e busca identificar quais fatores explicam seu desenho. Existe uma literatura consolidada que nos permite compreender a diversidade das respostas provinciais à política nacional de proteção das florestas nativas. No artigo discutimos esta literatura e propomos uma hipótese que reformula o peso relativo das variáveis em jogo para o caso estudado e eventualmente para outros casos provinciais. O trabalho permite mostrar que o desenho do ordenamento de florestas nativas na província de Formosa é melhor explicado como resultado do confronto e negociação do governo provincial com as autoridades ambientais nacionais em torno da política nacional do que pela incidência de coalizões de atores sociais e estatais confrontando-se entre si. O resultado deste processo de ordenamento florestal permitiu ao governo provincial combinar uma política de desenvolvimento produtivista com as exigências da política ambiental nacional.

RESUMEN Este artículo analiza la implementación de la Ley de Bosques en la provincia de Formosa que, en contraste con otras provincias, otorgó a la mayoría de sus bosques nativos la categoría de protección más baja de la ley. Haciendo uso de una metodología cualitativa, el presente trabajo reconstruye el proceso de diseño y sanción del ordenamiento de bosques nativos en la provincia de Formosa y busca identificar qué factores explican su diseño. Existe una literatura consolidada que permite entender la diversidad de respuestas provinciales a la política nacional de protección de los bosques nativos. En el artículo discutimos esa literatura y planteamos una hipótesis que reformula el peso relativo de las variables en juego para el caso estudiado y eventualmente para otros casos provinciales. El trabajo permite mostrar que el diseño del ordenamiento de bosques nativos en la provincia de Formosa se explica mejor como resultado de la confrontación y negociación del gobierno provincial con las autoridades ambientales nacionales en torno a la política nacional que por la incidencia de coaliciones de actores sociales y estatales confrontadas entre sí. El resultado de este proceso de ordenamiento de bosques le permitió al gobierno provincial conjugar una política de desarrollo productivista con los requerimientos de la política ambiental nacional.

ABSTRACT This paper analyses the implementation of the Forest Law in the province of Formosa, which, in contrast with other provinces, granted most of its native forests the lowest category of protection under the law. Using a qualitative methodology, this paper reconstructs the design and sanctioning process of native forest regulation in the province of Formosa and seeks to identify the factors that explain its design. There is a consolidated literature that allows us to understand the diversity of provincial responses to the national policy for the protection of native forests. In this paper we discuss this literature and propose a hypothesis that reformulates the relative weight of the variables at stake for the case studied and eventually for other provincial cases. The paper shows that the design of native forest management in the province of Formosa can be better explained as a result of the confrontation and negotiation of the provincial government with the national environmental authorities around the national policy, than by the incidence of coalitions of social and state actors confronting each other. The result of this forest management process allowed the provincial government to combine a production-oriented development policy with the requirements of the national environmental policy.

Resumen Durante las últimas décadas en Puno, Perú, la problemática de la contaminación se fue agudizando por la acción combinada del crecimiento desordenado de la población urbana, gestión deficiente de residuos sólidos, descarga de aguas servidas sin tratamiento en la bahía del lago Titicaca y prácticas de sanidad e higiene inadecuadas; situaciones que afectan severamente el ambiente y la salud humana. El objetivo del estudio fue caracterizar las actitudes y comportamientos proambientales de la población de la ciudad de Puno en relación al saneamiento, la contaminación y la gestión ambiental. La investigación es no experimental, cuantitativa, trans¬versal, descriptiva, correlacional y nivel de análisis micro. El universo de estudio fue la población mayor de 18 años del área urbana, que comprende 97.264 habitantes; la muestra, deter¬minada al azar simple, fue de 382 personas. Se aplicó un cuestionario estructurado. El análisis descriptivo, inferencial y prueba de hipótesis se realizó con el software estadístico SPSS. Los resultados señalan que las actitudes ambientales de la mayoría de la población son positivas respecto a factores y fuentes de contaminación y efectos en la salud humana; contrariamente, las prácticas ambientales son inadecuadas en gestión ambiental en el hogar y condiciones de sanidad e higiene en la vivienda. Se concluye, que la mejora sostenible de actitudes y comportamientos proambientales, demanda de una nueva política pública de educación ambiental, cuya implementación incorpore la participación efectiva de la sociedad civil con base a un sistema de incentivos.

Abstract During the last decades in Puno, Peru, the problem of contamination has worsened due to the combined action of the disorderly growth of the urban population, poor management of solid waste, discharge of untreated sewage into the bay of Lake Titicaca and practices of inadequate sanitation and hygiene, severely affecting the environment and human health. The objective of the study was to characterize the pro-environmental attitudes and behaviors of the city’s population of Puno in relation to sanitation, pollution and environmental management. The research is nonexperimental, quantitative, cross-sectional, descriptive, correlational and micro level of analysis. The universe of study was the population over 18 years of age in the urban area, which comprises 97,264 inhabitants; the sample, determined at simple random, was 382 people. A structured questionnaire was applied. Descriptive and inferential analysis and hypothesis testing were performed with SPSS statistical software. The results indicate that the environmental attitudes of the majority of the population are positive regarding factors and sources of pollution and effects on human health. On the contrary, environmental practices are inadequate in environmental management in the home and health and hygiene conditions in the home. It is concluded that the sustainable improvement of pro-environmental attitudes and behaviors demands a new public policy of environmental education, whose implementation incorporates the effective participation of civil society based on an incentive system.

BACKGROUND: Despite inpatient rehabilitation many stroke survivors struggle with community reintegration on returning home. The environment to which the stroke survivor returns affects and may limit participation in home and community-based activities. AIM: To describe stroke survivors' lived experiences of the environmental barriers and facilitators to community reintegration in an under resourced urban metropolitan sub-district in the Western Cape, South Africa. METHODS: A descriptive, qualitative study design with a phenomenological emphasis used semi-structured interviews to collect the data from purposefully selected stroke survivors who had been discharged for more than one year following inpatient rehabilitation. Supporting data were collected from interviews with two occupational therapists providing rehabilitation services to the stroke survivors. Deductive priori coding of semi-structured interviews with 11 stroke survivors, based on the environment subsystems described in the Person-Environment-Occupation-Performance (PEOP) model explored the barriers and facilitators to their community reintegration. FINDINGS: Of the six environmental sub systems in the PEOP model the systems and policy, access to information and health education, social determinants of health in the form of poor rehabilitation planning and loss of income as well as the built and natural environment presented the greatest barriers to the stroke survivor participants' community reintegration. However, reintegration was facilitated by social support and social capital, social determinants of health in the form of support groups as well as assistive technologies. CONCLUSION: Community reintegration continues to be a challenge for stroke survivors in an under-resourced urban sub-district due to environmental barriers associated with factors such as poor social support, inadequate implementation of policies and systems, poor compliance with home programmes, low socioeconomic status, poor access within the built and natural environment and inappropriate assistive devices. Several facilitators that occupational therapists can focus on to enable community reintegration included ensuring effective social support, access to community-based organisations, the introduction of home visits and provision of appropriate assistive devices. IMPLICATIONS FOR PRACTICE All stroke survivors must receive a comprehensive discharge plan to facilitate adequate access to continued rehabilitation and support for successful community reintegration. • There must be a specific referral to primary health care rehabilitation services on discharge from hospital. • Occupational therapists at community level have the responsibility to: o advocate for, or assist stroke survivors to self-advocate, the removal of inter-sectoral environmental barriers that limit their community reintegration and community participation, o where possible provide services in the home and involve midlevel workers when conducting home visits to enable successful reintegration into the home and resumption of occupational roles where possible, o look to other resources in their community that can assist in facilitating the community reintegration of stroke survivors to enable access to health, education, productive activities, and social and leisure participation opportunities, o improve their collaboration with the communities that they service.

INTRODUCTION: South Africa has a high unemployment rate and few post-school employment opportunities for learners with disabilities. School-to-work transition programmes in special educational needs schools prepare learners with disabilities for work in the open labour market, optimizing post-school employment opportunities. Occupational therapists are the main key role players in facilitating school-to-work transition programme in many contexts of education. AIM: This study explores the perceptions of occupational therapists of a school-to-work transition programme at the school for learners with special needs. METHODS: This study was a descriptive qualitative study. The researchers conducted semi-structured interviews with six occupational therapists involved in delivering the programme at the school. To ensure ethical compliance, we obtained clearance from the UP-Research Ethics Committee. The collected data underwent reflective thematic analysis for interpretation. FINDINGS: Three prominent themes emerged from the data analysis: (1) The Significance of the Programme: Participants highlighted the importance and benefits of the program. (2) Facilitators affecting school-to-work transition programme: Various factors that positively influenced the smooth transition from school to the workforce were identified and discussed. (3) Barriers to school-to-work transition programme: Participants also pointed out obstacles and challenges that hindered the successful transition from school to the workforce. CONCLUSION: The school-to-work transition programme was influenced by personal, environmental, and occupational barriers and facilitators. The findings highlighted that the benefits of the programme should be viewed in a broader context, as learners mature and develop self-confidence. The value of the programme thus extends beyond employment opportunities. IMPLICATIONS FOR PRACTICE The research findings inform barriers that need to be focused on in order to have a successful and effective school-to-work transition programme. There are facilitators that show the perceived effectiveness of the school-to-work transition programme that could assist in motivating for more assistance from stakeholders of the school.

RESUMEN Introducción: Los brotes recurrentes de dengue subrayan la necesidad de abordajes más efectivos en la prevención y control de vectores. A menudo, las intervenciones se centran en un enfoque biomédico y de promoción de la salud desde un enfoque individual, sin integrar factores socioambientales ni ser evaluados científicamente Objetivo: Evaluar el impacto de la recolección de residuos domésticos de gran tamaño sobre potenciales criaderos de mosquitos transmisores del dengue en Asunción, Paraguay durante los años 2017 a 2021. Material y métodos: Estudio cuasiexperimental, longitudinal, donde se encuestaron 350 hogares, como línea de base durante el 2017 y una línea de cierre en 108 hogares en 2021. Se utilizó el método de Diferencia en Diferencia (DID) para comparar la presencia de criaderos antes y después de la intervención en 43 hogares intervenidos y 65 no intervenidos. Resultados: La recolección diferenciada fue utilizada principalmente por aquellos hogares que tenían una gran cantidad de residuos sólidos de gran tamaño, pero no para deshacerse de todos estos objetos, sino sólo de una parte (DID de -52% en el número total de criaderos y DID de 1% en número de hogares con criaderos). Encontramos una reducción significativa en el número de total de criaderos de gran tamaño, pero no observamos diferencias en el número total de hogares con criaderos. Factores subjetivos, como la creencia de que los objetos en desuso podrían llegar a ser útiles en el futuro explicaban en gran medida su presencia en los hogares, incluso con el servicio disponible. Conclusiones: El enfoque de la gestión municipal en los residuos voluminosos puede contribuir a la prevención del dengue por el hecho de que no constituyen residuos de generación rápida en los hogares, y su eliminación puede tener un impacto relativamente duradero. El factor subjetivo relacionado con la presencia de estos criaderos en los hogares debe ser objeto de mayores estudios.

ABSTRACT Introduction: Recurrent dengue outbreaks underscore the need for more effective approaches to vector prevention and control. Often, interventions focus on a biomedical and health promotion approach from an individual approach, without integrating socio-environmental factors or being scientifically evaluated. Objetive: To evaluate the impact of large household waste collection on potential breeding sites of dengue-transmitting mosquitoes in Asuncion, Paraguay during the years 2017 to 2021. Material and methods: Quasi-experimental, longitudinal study, where 350 households were surveyed, as a baseline during 2017 and a closing line in 108 households in 2021. The Difference-in-Difference (DID) method was used to compare the presence of breeding sites before and after the intervention in 43 intervened and 65 non-intervened households. Results: Differentiated collection was mainly used by those households that had a large amount of large solid waste, but not to dispose of all these objects, but only part of them (DID of -52% in the total number of breeding sites and DID of 1% in the number of households with breeding sites). We found a significant reduction in the total number of large breeding sites but did not observe differences in the total number of households with breeding sites. Subjective factors, such as the belief that disused objects could become useful in the future, were largely responsible for the reduction in the number of large breeding sites. Conclusions: The municipal management approach to bulky waste can contribute to dengue prevention because it does not constitute rapidly generated waste in households, and its disposal can have a relatively long-lasting impact. The subjective factors related to the presence of these breeding sites in households warrant further study.

ABSTRACT Introduction: Influenza is a global threat, with high epidemic potential and affects between 5 and 15% of the world's population annually. In the hospital environment, vaccination is crucial to protect healthcare professionals. However, despite international recommendations, vaccination uptake is low due to safety concerns and/or distrust. Studies show that vaccinated professionals have lower rates of absenteeism, and when infected with the virus, they present milder symptoms. In this work, a retrospective cross-sectional observational study is carried out on the vaccination rate against this disease in a population of hospital-based workers, from 2019 to 2023. To understand the importance of vaccination against Influenza in these workers and which behavioral determinants may justify considering this evolution, we carried out a review of the challenges of vaccination among health professionals and identified key points to develop strategies with the aim of promoting adherence to vaccination campaigns. Methodology: For the observational study, vaccination data from hospital health professionals by the Occupational Health Service was used, recorded on a specific form at the time of administration. Professional category was the only variable considered. Data analysis was performed using Microsoft® Excel®. For the review, the databases Medline, Science Direct and Google Scholar were used, with the keywords "Influenza vaccine”, “health professional” and “behaviour”, selecting studies from 2010 to 2024. From the result of 1277 works, the exclusion criteria, which included vaccination for other diseases and target populations that did not include health professionals, 22 bibliographic sources were selected. To reflect the national reality, articles on the topic published by the Revista Portuguesa de Saúde Ocupacional Online were included, as well as complementary studies and reference documents. Results: The study of adherence to flu vaccination in this hospital peripheral to Lisbon, between 2019 and 2023, showed a variation in vaccination adherence, with an average of 30%, a value below the ones reported in other countries. The categories most hesitant about this vaccine were Nursing Staff and Technical Assistants; at the opposite extreme, there was greater adherence from Medical Personnel and Technical Assistants. During the COVID-19 Pandemic, an increasing number of professionals were vaccinated annually, with this trend reversing after the end of the global emergency of this disease. From the review of the literature on vaccine hesitancy, 8 of the 14 behavioral domains stand out that represent theories of behavioral change that constitute modifiable factors that influence behavior in relation to the vaccine. We approach each of them from this perspective, namely: knowledge, the environmental context and resources, social influence, beliefs and knowledge about consequences, beliefs about individual capacity, identity and social/professional role, reinforcement and emotion. Discussion: Flu vaccine hesitancy among healthcare professionals can be a cause of morbidity and mortality for patients. Understanding the barriers and motivation for healthcare professionals to adhere to flu vaccination campaigns is crucial. Professionals who are asymptomatic carriers become sources of transmission. Annual vaccination, although safe and effective, faces variability due to antigenic concordance. In Portugal, educational and communication strategies are vital, highlighting the role of health professionals as models of preventive behavior. Easy access to medical consultations and Occupational Health recommendations is associated with greater adherence. In times of pandemic, the propensity for vaccination has increased, and it is important to promote this change. Strategies adapted to the cultural context are essential to boost adherence to Influenza vaccination among healthcare professionals. Conclusion: The approach to combating barriers and promoting vaccination among healthcare professionals must involve multiple areas and multiple levels, with communication targeted at specific groups, to increase its effectiveness. The message must be adapted to different population groups and different levels of health literacy. Knowing these behavioral determinants can help develop vaccination promotion campaigns from new perspectives and finding strategies to increase vaccination coverage is crucial for Occupational Health Services. Due to the ethical characteristics of the professions involved in providing direct care to patients, there is a need to reinforce the idea that vaccination among healthcare professionals is not only for their benefit, but above all for the protection of their patients.

RESUMO Introdução: A Gripe é uma ameaça global, com alto potencial epidémico e afeta anualmente entre 5 a 15% da população mundial. No ambiente hospitalar, a vacinação é crucial para proteger os Profissionais de Saúde. No entanto, apesar das recomendações internacionais, a adesão é baixa devido a preocupações de segurança e/ou desconfiança. Estudos mostram que os profissionais vacinados têm menores taxas de absentismo e, perante infeção pelo vírus, apresentam sintomatologia mais ligeira. Neste trabalho é realizado um estudo observacional transversal retrospetivo da taxa de vacinação contra esta doença numa população de trabalhadores de base hospitalar, no período de 2019 a 2023. Para compreender a importância da vacinação contra a Influenza nestes trabalhadores e quais os determinantes comportamentais que podem justificar esta evolução, realizou-se uma revisão dos desafios da vacinação entre Profissionais de Saúde, para identificar pontos chave e elaborar estratégias com o objetivo de promover a adesão às campanhas de vacinação. Metodologia: Para o estudo observacional da taxa de adesão à vacinação contra a Gripe num hospital periférico foram utilizados os dados de vacinação dos Profissionais de Saúde disponibilizados nos registos do Serviço de Saúde Ocupacional. A categoria profissional foi a única variável considerada. A análise dos dados foi realizada com o Microsoft® Excel®. Para a revisão recorreu-se às bases de dados Medline, Science Direct, Google Scholar; com as palavras-chave "Influenza vaccine”; “health professional” e “behaviour" e filtraram-se estudos de 2010 a 2024. Resultaram 1277 trabalhos e, após aplicar os critérios de exclusão, que incluíam vacinação para outras doenças e populações alvo que não os Profissionais de Saúde, foram selecionadas 22 fontes bibliográficas. Para espelhar a realidade nacional foram incluídos os artigos sobre o tema publicados pela Revista Portuguesa de Saúde Ocupacional Online, assim como estudos complementares e documentos de referência. Resultados: O estudo da adesão à vacinação contra a Gripe neste hospital periférico a Lisboa, entre 2019 e 2023, mostrou uma variação na adesão à vacinação, com uma média de 30%, valor abaixo dos valores reportados noutros países. As categorias com maior hesitação a esta vacina foram o Pessoal de Enfermagem e os Assistentes Técnicos. Na situação oposta estavam o Pessoal Médico e os Assistentes Técnicos. Durante a Pandemia COVID-19 existiu um número crescente de profissionais vacinados anualmente, tendo esta tendência invertido após o fim da emergência global desta doença. Da revisão da bibliografia sobre a hesitação vacinal destaca-se 8 dos 14 domínios comportamentais que representam as teorias de mudança comportamental que constituem fatores modificáveis que influenciam a atitude em relação à vacina. Abordou-se sobre esta perspetiva cada um deles, nomeadamente, o conhecimento; o contexto ambiental e recursos; influência social; crenças e conhecimento sobre consequências; bem como sobre a capacidade individual; identidade e papel social/profissional; reforço e emoção. Discussão: A hesitação vacinal contra a Gripe entre Profissionais de Saúde pode ser uma causa de morbilidade e mortalidade para os doentes. Compreender as barreiras e motivação para a adesão dos Profissionais de Saúde às campanhas de vacinação contra a Gripe é crucial. Profissionais portadores assintomáticos, tornam-se fontes de transmissão. A vacinação anual, embora segura e eficaz, enfrenta variabilidade devido à concordância antigénica. Em Portugal, estratégias educacionais e de comunicação são vitais, destacando o papel dos Profissionais de Saúde como modelos de comportamento preventivo. O acesso fácil a consultas médicas e tal ser recomendado pela Saúde Ocupacional é associado a maior adesão. Em tempos de pandemia, a propensão à vacinação aumentou, importando promover esta mudança. Estratégias adaptadas ao contexto cultural são essenciais para impulsionar a adesão à vacinação contra a Gripe entre Profissionais de Saúde. Conclusão: A abordagem para combater as barreiras e promover a vacinação nos Profissionais de Saúde deve envolver múltiplas áreas e vários níveis, com uma comunicação dirigida a grupos específicos, para aumentar a sua eficácia. Deve adaptar-se a mensagem aos diferentes grupos populacionais e aos diferentes níveis de literacia em saúde. Conhecer estes determinantes comportamentais pode ajudar a desenvolver campanhas de promoção da vacinação a partir de novas perspetivas e encontrar estratégias para aumentar a cobertura vacinal é crucial para os Serviços de Saúde Ocupacional. Pelas características éticas das profissões envolvidas na prestação de cuidados diretos aos doentes, existe a necessidade de reforçar a ideia de que a vacinação entre Profissionais de Saúde não é apenas para seu benefício mas, acima de tudo, para proteção dos seus doentes.

ABSTRACT Introduction/framework/objectives: Amyotrophic Lateral Sclerosis is a disease that can progress in a debilitating manner and affect some individuals of working age, so it will be important that professionals working in Occupational Health and Safety have a reasonable set of knowledge on the subject, to be able to adjust work tasks as best as possible, as well as any protective measures, enhancing well-being and performance/productivity. Furthermore, knowing the work factors that increase it, it will be possible to slightly reduce the incidence of the pathology. The aim of this review was to summarize in Portuguese the most current and relevant articles published on the topic in international and national literature. Methodology: This is a Bibliographic Review, initiated through a search carried out in April 2023 in the databases “CINALH plus with full text, Medline with full text, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Cochrane Methodology Register, Nursing and Allied Health Collection: comprehensive, MedicLatina and RCAAP”. Content: This pathology is a rapidly progressive neurodegenerative disease characterized by muscular atrophy/paralysis, generally beginning in adulthood with an average survival of two to three years. The first manifestations generally involve asthenia of the lower limbs, generally in the 5th or 6th decade of life. Focal paralysis intensifies and spreads, reaching the respiratory muscles and culminating in respiratory failure. However, the pathophysiology is not clearly understood. Some researchers consider that the only environmental fact that could have any influence could be smoking; others even claim that the influence of global environmental exposure itself is controversial. At this level, with greater or lesser consensus, pesticides, fertilizers, solvents, heavy metals, formaldehyde, diesel, physical exertion/hypoxia, trauma and contact with electricity stand out. Therefore, there are also some professional sectors that may present greater risk. Discussion and Conclusions: Even though the prevalence of this pathology is low, some of these individuals are part of the active population, at least at an initial stage. No concrete data was found regarding protective measures or other relevant attitudes for the Health and Safety team to guide in this context. Even so, the authors succinctly recorded some items in this sense, depending on their professional experience, especially for pathologies with some similarities and more prevalent. It would be interesting for professionals working in a hospital environment, in an institution where there is a support consultation for users with this pathology, to focus a little on the topic, portraying the national reality and publishing their research in a magazine in the area, to disseminate knowledge at national level, with international extrapolation, given the scarcity of bibliography.

RESUMO Introdução/enquadramento/objetivos: A Esclerose Lateral Amiotrófica é uma doença que poderá evoluir de forma debilitante e atingir alguns indivíduos em idade ativa, pelo que será relevante que os profissionais a exercer na Saúde e Segurança Ocupacionais tenham um conjunto razoável de conhecimentos sobre o tema, de forma a conseguirem ajustar o melhor possível as tarefas laborais, bem como eventuais medidas de proteção, potenciando o bem-estar e desempenho/produtividade. Para além disso, conhecendo os fatores laborais que a potenciam, poder-se-á diminuir um pouco a incidência da patologia. Pretendeu-se com esta revisão resumir em português o que de mais atual e relevante se publicou sobre o tema nas literaturas internacional e nacional. Metodologia: Trata-se de uma Revisão Bibliográfica, iniciada através de uma pesquisa realizada em abril de 2023 nas bases de dados “CINALH plus with full text, Medline with full text, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Cochrane Methodology Register, Nursing and Allied Health Collection: comprehensive, MedicLatina e RCAAP”. Conteúdo: Esta patologia é uma doença neurodegenerativa rapidamente progressiva e caraterizada por atrofia/paralisia muscular, geralmente iniciada na idade adulta com sobrevida média de dois a três anos. As primeiras manifestações geralmente incidem na astenia dos membros inferiores, geralmente na 5ª ou 6ª décadas de vida. A paralisia intensifica-se e alastra-se, podendo atingir os músculos respiratórios e culminar em insuficiência respiratória. Contudo, a fisiopatologia não está esclarecida com clareza. Alguns investigadores consideram que o único fator ambiental que poderá ter alguma influência poderá ser o tabagismo; outros até afirmam que a influência da exposição ambiental global em si é controversa. Neste contexto, com maior ou menor consenso, destacam-se os pesticidas, fertilizantes, solventes, metais pesados, formaldeído, diesel, esforço físico/hipoxia, trauma e contato com a eletricidade. Desta forma, existem também alguns setores profissionais que poderão apresentar maior risco. Discussão e Conclusões: Ainda que a prevalência desta doença seja baixa, parte destes indivíduos estão inseridos na população ativa, pelo menos numa fase inicial. Não se encontraram dados concretos relativos a medidas de proteção ou outras atitudes relevantes para a equipa de Saúde e Segurança orientar neste contexto; ainda assim, os autores registaram de forma sucinta alguns itens nesse sentido, em função da sua experiência profissional, sobretudo para patologias com algumas semelhanças e mais prevalentes. Seria aliciante que profissionais a exercer em ambiente hospitalar, em instituição que exista uma consulta de apoio a utentes com esta patologia, se debruçassem um pouco sobre o tema, retratando a realidade nacional e publicando a sua investigação em revista da área, para difusão de conhecimentos a nível nacional, com extrapolação internacional, dada a escassez de bibliografia.
