This study presents a solution to solid waste problems, focusing on spent lithium-ion batteries (LiBs) and iron ore tailings (IOT) from the Mariana environmental accident in Brazil. The approach involves the production CoFe2O4 from LiBs and IOT, which serves as a catalyst for solar photo-Fenton reactions for methylene blue (MB) decolorization and as an electrochemical sensor for ascorbic acid (AA) detection. Chemical analysis showed recycling potential, with 45.22 ± 0.22% m m−1 Co from LiBs and 14.9 ± 1.5% m m−1 Fe from IOT, determined by inductively coupled plasma atomic emission spectroscopy (ICP OES) and flame atomic absorption spectrometry (FAAS). The sol-gel synthesized CoFe2O4 exhibited a crystallite size of 51.9 ± 1.3 nm and agglomerated crystal clusters. Recycled-CoFe2O4 exhibited a 98.1% MB decolorization efficiency in 60 min under solar irradiation and remained above 92.3% in all 7 reuse cycles. The electrochemical sensor exhibited a coefficient of determination of 0.9987, a sensitivity of 3.352 ± 0.0428 μA mol L−1, and a limit of detection of 0.5511 µM in the concentration range of 1.96 to 23.08 mmol L−1 for AA detection. This study demonstrates the potential of recycled-CoFe2O4 in an environmentally friendly dye removal and as an electrochemical sensor, offering sustainable waste management and resource utilization with solar energy. problems lithiumion lithium ion (LiBs IOT (IOT Brazil CoFeO CoFe O CoFe2O photoFenton photo Fenton (MB (AA 4522 45 22 45.2 022 0 0.22 m1 1 m− 149 14 9 14. 15 5 1.5 ICP OES FAAS.

The training of Chemistry teachers in Brazil has been researched for a few decades and studies point out to training gaps that reverberate in teaching, especially in basic education. One of the contents covered in this step and which is part of the high school curriculum is radioactivity, which is related, among other things, to radiological and radioactive accidents that occur around the world. Thus, this research sought to investigate how the training provided to Chemistry undergraduates in the state of Goiás is in relation to the subject of radioactivity, since in 1987 a radiological accident occurred in Goiânia with a Cesium 137 source. This is a qualitative research, data were collected via questionnaire and the analytical technique used was discursive textual analysis (ATD). The results showed that due importance was not given to the radiological accident, since there is evidence of training gaps in relation to the topic of radioactivity in Chemistry degree courses in the state of Goiás, where the accident occurred, and the contents on radioactivity are either not addressed, or the approach is superficial. This fact directly impacts the teacher’s performance in basic education, when working on this content with their students. teaching education related things world Thus 198 13 source ATD. ATD .

ABSTRACT Introduction/framework/objectives Salt production, especially using artisanal methods, does not exist in all countries, given the climatic and logistical requirements. Portugal has some tradition in this sector, but even so, most professionals working in Occupational Health and Safety have no experience in the area. The aim of this review was to summarize the most relevant and recent publications, to improve their performance capacity and enhance the productivity, satisfaction and well-being of the workers involved. 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 Salt pans can be inland (far from the sea, using groundwater with a high salt content) or coastal. The former are scarcer in Portugal and only exist between Lisbon and Coimbra. Over time, in our country, evaporation was carried out by fire and sun. The latter is believed to have been developed by the Romans who created the first version of salt flats. At national level there is evidence of salt production since the end of the Neolithic, but here more frequently with the use of fire. Throughout Europe there has been a decline in artisanal versus industrial salt production, even in sea salt pans (especially on the northwest coast of France and, in Portugal, on the western coasts). Artisanal production in our country is more prevalent in the Figueira da Foz area. The product obtained via artisanal production has better quality, particularly in terms of flavor and nutritionally (via industrial production the taste is more metallic). Portugal is a large producer and consumer of traditional salt. The climatic characteristics suit production, due to summers with frequent high temperatures and strong, hot winds. National salt was and is consumed in other European countries; for presenting superior quality, even though it is more expensive. Production depends on the climate, namely insolation (number of hours in the sun), precipitation, temperature, cloudiness and winds (which affect evaporation). In other words, this is more intense and faster if the air temperature is higher, such as with more dry winds (which are generally more frequent in summer); low precipitation is also favorable. Salt production has been increasing, due to growing industrial needs. To be used in this last situation, it must be at 100% purity. Discussion and Conclusions No bibliography was found that referred the dimension of occupational health and safety in this professional sector. Based on the authors' theoretical and practical experience, the most relevant risk factors and risks in the sector are described: ultraviolet radiation and possible skin cancer, cataracts and other associated injuries; thermal discomfort and eventual higher accident rates associated with motor incoordination, worse cardiovascular adjustment, as well as disorientation and ability to make decisions; forced/maintained loads and/or postures and possible musculoskeletal injuries, emergence/worsening of hernia pathology and falling objects at the same level and possible bruises, skin lacerations and/or fractures. It would be interesting to learn more about the national panorama of this sector, through studies that hierarchically stratify the risk, also accurately describing occupational illnesses and associated accidents, as well as more effective measures to mitigate these issues.

RESUMO Introdução/enquadramento/objetivos A produção de sal, sobretudo com métodos artesanais, não existe em todos os países, dadas as exigências climáticas e logísticas. Portugal apresenta alguma tradição nesse setor mas, ainda assim, a maioria dos profissionais a exercer na Saúde e Segurança Ocupacionais não tem experiência na área. Pretendeu-se com esta revisão resumir o que mais relevante e recente se publicou, de forma a melhorar a capacidade de atuação destes e a potenciar a produtividade, satisfação e bem-estar dos trabalhadores afetos. 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 As salinas podem ser interiores (afastadas do mar, usando água subterrânea com elevado conteúdo em sal) ou litorais. As primeiras são mais escassas em Portugal e apenas existem entre Lisboa e Coimbra. Ao longo do tempo, no nosso país, a evaporação era realizada pelo fogo e sol. Esta última acredita-se que foi desenvolvida pelos romanos que, de certa forma, criaram a primeira versão das salinas. A nível nacional há evidência de produção de sal desde o final do Neolítico, mas aqui mais frequente com a utilização do fogo. Por toda a Europa tem existido um declínio da produção artesanal de sal, versus industrial, mesmo em salinas marítimas (sobretudo na costa noroeste de França e, em Portugal, na costa ocidental). A produção artesanal no nosso país é mais prevalente na zona da Figueira da Foz. O produto obtido via artesanal tem mais qualidade, nomeadamente a nível de sabor e nutricionalmente (via industrial o paladar é um pouco mais metálico). Portugal é um grande produtor e consumidor de sal tradicional. As caraterísticas climáticas adequam-se à produção, devido aos verões com temperaturas elevadas frequentes e ventos fortes e quentes. O sal nacional era e é consumido noutros países europeus, por apresentar qualidade superior, mesmo tendo um preço mais elevado. A produção depende do clima, nomeadamente a insolação (número de horas ao sol), precipitação, temperatura, nebulosidade e ventos (que condicionam a evaporação). Ou seja, esta é mais intensa e rápida se a temperatura do ar for mais elevada, tal como com mais ventos secos (que geralmente são mais frequentes no Verão); a baixa precipitação também é favorável. A produção de sal tem vindo a aumentar, até pelas crescentes necessidades industriais. Para ser usado nesta última situação, deverá estar no patamar de 100% de pureza. Discussão e Conclusões Não se encontrou bibliografia que fizesse referência à dimensão da saúde e segurança ocupacionais neste setor profissional. Em função de experiência teórica e prática dos autores, descrevem-se os fatores de riscos e riscos mais relevantes do setor: radiação ultravioleta e eventual cancro de pele, cataratas e outras lesões associadas; desconforto térmico e eventual maior sinistralidade associada a descoordenação motora, pior ajuste cardiovascular, bem como desorientação e capacidade de tomar decisões; cargas e/ou posturas forçadas/mantidas e eventuais lesões músculo-esqueléticas, surgimento/agravamento de patologia herniária e queda de objetos e ao mesmo nível e eventuais equimoses, lacerações cutâneas e/ou fraturas. Seria interessante conhecer melhor o panorama nacional deste setor, através de estudos que estratificassem hierarquicamente o risco, descrevendo ainda com rigor as doenças profissionais e acidentes associados, bem como medidas mais eficazes para atenuar essas questões.

ABSTRACT Introduction: a pressure ulcer is an injury that is located at the level of the skin and deeper tissues. The beginning of the appearance of pressure ulcers can constitute a major problem in the health of patients, causing physical discomfort, increasing hospitalization time and treatment costs. Objectives: describe the prevalence of hospitalized patients with pressure ulcers in the medical clinic service of the modular block of the National Hospital, 2022 - 2023.

ABSTRACT Introduction: Burns are devastating injuries associated with high morbidity and mortality. A disruption of the immune system is developed, affecting the function of neutrophils and lymphocytes, first defensing line against pathogens. In order to evaluate the association between the Neutrophil to Lymphocyte Ratio, and the prognosis of the burn injurie, the investigation was performed. Methods: . A descriptive, longitudinal, prospective investigation was developed at the Burn Unit of Calixto García Hospital, from January 2022nd to December 2022nd. All severely burned patients admitted, with ages between 19 and 60 years old, and less than 24 hours from the onset of the accident were included. Patients suffering from chronic conditions were excluded. To determinate the levels of Neutrophil to Lymphocyte Rates, blood samples were taken at the first 72 hours after injury and during the 6th day. A relationship between the levels of Neutrophil to Lymphocyte Ratio, and the prognosis of the trauma was established. Of a total of 134 patients admitted, 36th were included. Results: Male patients were the majority. Fire the main etiological agent, and accidents the first production mode. High levels of Neutrophil to Lymphocyte Ratio were detected since the first 72 hours after trauma, and stayed high during the 6th day of evolution. Patients with poorest life prognosis, showed higher levels of Neutrophil to Lymphocyte Ratio. Conclusion: A direct relationship was found between the levels of Neutrophil- to Lymphocyte Ratio and the severity of the burn injury, and the survival rate.

RESUMEN Introducción: Las quemaduras son lesiones devastantes que se asocian a alta morbilidad y mortalidad. Se produce desbalance inmunológico, afectando los leucocitos, primera línea de defensa ante cualquier noxa, fundamentalmente los neutrófilos y linfocitos.

Existió una asociación lineal entre los valores de Índice Neutrófilos/Linfocitos en lesionados egresados vivos y los que fallecieron, así como relación directamente proporcional con la gravedad de la lesión.

INTRODUCTION: The rising prevalence of stroke in sub-Saharan Africa necessitates the exploration of the role of occupational therapy in rehabilitation of stroke. In the southern African country of South Africa, occupational therapy aligns with healthcare policies and laws, and this article presents a review of synthesized evidence of occupational therapy intervention in stroke care and rehabilitation. METHOD: Rapid review methodology was used to develop a research question about cerebrovascular accident - intervention by occupational therapists., The Cochrane Library and MEDLINE databases were searched for relevant articles published between 2018 and 2023. Twenty four articles met the inclusion criteria and were analysed according to quantitative and qualitative parameters. RESULTS: Evidence of occupational therapy intervention with post-stroke upper limb impairment was found in 37,5% of articles. Occupational therapy for global improvement in function, cognitive rehabilitation, balance, social participation, work, and leisure comprised 45,8% of articles, and one article each reported evidence for occupational therapy addressing ADL and caregiver interventions. CONCLUSION: Evidence from the past five years reflect diverse occupational therapy interventions with clients with stroke. Gaps in recent evidence remain in relation to context-specific interventions, especially from low- and middle-income countries. IMPLICATIONS FOR PRACTICE Occupational therapists adopt a holistic approach to stroke rehabilitation, tailoring interventions to address the multifaceted needs and goals of individual stroke survivors. The effectiveness of individualised, occupation-based approaches across various domains are highlighted. • Therapists stay informed and up to date about emerging technologies and evidence-based practice to enhance their effectiveness in stroke rehabilitation. • This review provides evidence of the prevalence of upper limb impairments post-stroke, which will enable therapists to be well-versed in the diverse intervention approaches for upper limb rehabilitation as outlined in the literature reviewed, including technologies like Brain Computer Interface, Mental Practice, Mirror Therapy, and Action Observation Therapy. • Occupational therapy is vital in addressing cognitive impairments in stroke survivors, and practitioners can apply the evidence provided on interventions such as Virtual Reality and computer-assisted cognitive rehabilitation that have shown promise in improving cognition and ADL.

Resumen Introducción: Se presenta el caso clínico de un varón de 15 años con fracturas de huesos cortos del pie derecho como consecuencia de un accidente de tránsito. Tras 24 h de evolución, ingresa con disnea, desaturación, pico febril objetivo y posterior desarrollo de insuficiencia respiratoria. Ante la sospecha clínica de síndrome de embolia grasa, se solicita una angiotomografía pulmonar que confirma el diagnóstico. Se trata de una entidad inusual en pacientes con este tipo de fractura. El tratamiento inicial consistió en vigilancia estrecha en la unidad de cuidados intensivos, medidas de soporte con oxígeno suplementario, terapia respiratoria y manejo quirúrgico de las fracturas. La evolución clínica del paciente fue adecuada y el cuadro respiratorio se resolvió por completo. Conclusiones: El síndrome de embolia grasa secundario a fracturas de huesos cortos es un cuadro infrecuente; por lo tanto, es preciso tener un alto grado de sospecha diagnóstica, no solo en los escenarios más comunes, sino también en este tipo de contextos inusuales y retadores, que permita su identificación temprana y, de esta forma, implementar un manejo oportuno y generar un impacto favorable en los desenlaces clínicos y en la disminución del riesgo de secuelas a largo plazo.

Abstract Introduction: We present the clinical case of a 15-year-old male who sustained fractures to the short bones of his right foot as a result of a traffic accident. After 24 hours of evolution, he was admitted for dyspnea, desaturation, an objective febrile peak, and the development of respiratory failure. Given the clinical suspicion of fat embolism syndrome, pulmonary angiotomography was requested, which confirmed the diagnosis. This is a rare finding in patients with this type of fracture. The initial treatment included close monitoring in the intensive care unit, supportive measures such as supplemental oxygen, respiratory therapy, and surgical fracture management. The patient’s clinical progression was adequate, and the respiratory condition resolved completely. Conclusion: Fat embolism syndrome resulting from short bone fractures is a rare condition; therefore, it is necessary to have a high level of diagnostic suspicion, not only in the most common scenarios, but also in these unusual and challenging contexts, which allows for its early detection and, as a result, timely management, which has a positive impact on clinical outcomes and reduces the risk of long-term sequelae.

ABSTRACT Introduction: Overactive bladder is characterized by overactivity of the detrusor and causes urge urinary incontinence. Accidents at work have a negative impact on the health of workers and consequently on the productivity of companies and the global economy. The worker and his/her family members are entitled to compensation for damage resulting from it. The responsibility for the repair and other charges arising from accidents at work lies with the employer, who is obliged to transfer it to entities legally authorized for this purpose (insurance companies). Case Report: In this clinical case, an accident at work is described in a 57-year-old woman, an operational assistant at a public health institution. The victim suffered a fall on a wet floor, which resulted in a rupture of the adductor muscles of the thighs, with aggravation of a pre-existing pathology (surgically corrected stress urinary incontinence). A few years after the accident, the victim underwent a new urogynecological surgical intervention at the insurance company, with worsening of existing stress incontinence and emergence of urge urinary incontinence, having developed, in this context, overactive bladder. Discussion/Conclusion: In this case report, the insurance company recognized the causal link between the accident at work and the injuries that developed. The consequences of this accident go beyond the work sphere, with an impact on the quality of life, leisure and sexual dimension of the worker. The reparation of damage by work accidents in Portugal focuses essentially on the loss of earning capacity. Occupational health services play a key role both in the prevention of accidents at work and in the follow-up of victims after returning to work. Occupational physicians and insurance companies play a key role in professional reintegration, so their communication and bonding should be strengthened.

RESUMO Introdução: A bexiga hiperativa caracteriza-se por hiperatividade do detrusor e ocasiona incontinência urinária de urgência. Os acidentes de trabalho têm um impacto negativo na saúde dos trabalhadores e consequentemente na produtividade das empresas e economia global. O trabalhador e os seus familiares têm direito à reparação dos danos emergentes. A responsabilidade pela reparação e demais encargos decorrentes cabe ao empregador, que é obrigado a transferi-la para entidades legalmente autorizadas para o efeito (seguradoras). Caso Clínico: Neste caso clínico descreve-se um acidente laboral numa trabalhadora de 57 anos, assistente operacional de uma instituição pública de saúde. A sinistrada sofreu queda em piso molhado, que resultou em rotura dos músculos adutores das coxas, com agravamento de patologia pré-existente (incontinência urinária de esforço corrigida cirurgicamente). Alguns anos após o acidente, a sinistrada foi submetida a nova intervenção cirúrgica uro-ginecológica na seguradora, com agravamento da incontinência de esforço já existente e surgimento de incontinência urinária de urgência, tendo desenvolvido, nesse contexto, bexiga hiperativa. Discussão/Conclusão: No caso clínico em questão, foi reconhecido pela companhia de seguros o nexo de causalidade entre o sinistro ocorrido e as lesões desenvolvidas. As consequências ultrapassam a esfera laboral, com impacto na qualidade de vida, lazer e dimensão sexual da trabalhadora. A reparação por acidentes de trabalho em Portugal incide essencialmente na perda da capacidade de ganho. Os serviços de saúde ocupacional têm um papel fundamental tanto na prevenção dos acidentes, como no acompanhamento dos sinistrados após regresso ao trabalho. O médico do trabalho e as companhias de seguro têm um papel fundamental na reintegração profissional, pelo que a sua comunicação e vínculo devem ser reforçados.

ABSTRACT Introduction: Musculoskeletal injuries related to work are extremely common, often resulting from workplace accidents. The knowledge of occupational diseases and injuries by the Occupational Health Physician is crucial for Occupational Medicine. This clinical case describes a 37-year-old male patient who sought Emergency Services due to a fall from stairs with right knee trauma involving hyperflexion during work. The diagnosis confirmed a complete rupture of the patellar tendon. With this clinical case, it was made a review of the literature about occupational and personal risk factors for patellar tendon rupture; as to investigate whether the literature describes any sequelae of the injury that may result in work limitations. Methods: A non-systematic literature review was conducted using the PubMed database with the keywords "Patellar tendon; knee injury; outcome; patellar tendon repair." Two articles not included in this filter were added for their relevance to the topic. Out of 56 articles published as systematic reviews and classic reviews between 2002 and 2022, a total of 23 articles were selected through the reading of abstracts. Exclusion criteria included bilateral rupture of the patellar tendon, studies exclusively focused on patellar tendon rupture in a sports context, and approaches to new surgical techniques. After reading these bibliographic sources, seven were used in the discussion of this clinical case. Results: Patellar tendon rupture is an uncommon and disabling injury with a higher incidence in men under 40 years old. In cases of total tendon rupture, surgical intervention is necessary to restore the extensor mechanism's functionality. Various authors have described potential predisposing conditions for patellar tendon rupture, such as the use of corticosteroids and fluoroquinolones, diabetes, rheumatic disease, Lyme disease and microtrauma. Most described cases are sports-related injuries. The relationship with occupational risk factors is not clear, except for professional athletes. Repetitive microtrauma is one of the main causes of patellar tendinopathy, which can lead to patellar tendon rupture and is defined as "overuse pathology," present in professions such as floor installers. Conclusion: Occupational medicine plays a relevant role in reintegrating workers after a workplace accident. Understanding the epidemiology, identifying injury mechanisms, treatment and prognosis of this pathology is important not only for preventing future workplace accidents but also for adapting the worker's return to their job.

RESUMO Introdução: As lesões músculo-esqueléticas ligadas ao trabalho são extremamente frequentes e muitas decorrentes dos acidentes laborais. O conhecimento das doenças e lesões provadas em contexto ocupacional é importante para a Medicina do Trabalho. Na descrição deste caso clínico apresenta-se um trabalhador de 37 anos, sexo masculino, que recorre ao Serviço de Urgência por queda de escadas com traumatismo do joelho direito com mecanismo de hiperflexão durante o trabalho. Após confirmação de diagnóstico de rotura total do tendão rotuliano. Com este caso clínico pretende-se rever na literatura a existência de fatores de risco ocupacionais e pessoais para esta situação clínica; bem como sequelas que possam configurar limitações na capacidade de trabalho. Métodos: Foi realizada a revisão de literatura não sistemática recorrendo a base de dados de artigos PubMed com as palavras-chave “Patellar tendon; knee injury; outcome; patellar tendon repair”. Foram incluídos dois artigos extra, pela sua relevância para o tema. Dos 56 estudos publicados como revisão sistemática e revisão, publicados entre 2002 e 2022, foram selecionados por leitura do resumo 23 documentos. Os critérios de exclusão foram rutura bilateral do rotuliano, estudos que dirigidos exclusivamente a rutura do rotuliano em contexto desportivo e abordagens a novas técnicas cirúrgicas. Após leitura destas fontes bibliográficas foram usadas sete na discussão deste caso clínico. Resultados: A rotura do tendão rotuliano é uma lesão incomum e incapacitante com maior incidência em homens com idade inferior a 40 anos. Nos casos de rotura total do tendão, a intervenção cirúrgica é necessária para restaurar a funcionalidade do mecanismo extensor. Diferentes autores descreveram a possível predisposição a condições para rotura do tendão rotuliano como o uso de corticosteroides e fluoroquina, diabetes, doença reumática, doença de Lume e o microtrauma. A maioria dos casos descritos são lesões desportivas. A relação com fatores de risco ocupacionais não é clara, com exceção dos atletas profissionais. O microtrauma repetitivo é uma das principais causas de tendinopatia patelar, que pode levar a rotura do rotuliano e que é definida como “patologia de uso excessivo”, que pode estar presente em profissões como assentadores de pavimento. Conclusão: A medicina do trabalho tem um papel relevante na reintegração dos trabalhadores após em caso de acidente no local de trabalho. Conhecer a epidemiologia, identificar os mecanismos de lesão, tratamento e prognóstico desta patologia é importante, não só para atuar na prevenção de futuros acidentes de trabalho, mas também para adaptar o retorno do trabalhador ao seu posto de trabalho.

ABSTRACT Introduction/framework/objectives Most professionals working in Occupational Health and Safety have some notions regarding the distribution of Occupational Accidents versus gender, however, not all have had the opportunity to consult reasonably up-to-date data on this subject. The aim of this review was to clearly summarize not only some articles that addressed this subject, but also to have access to national and European statistical data. Methodology This is a Bibliographic Review, initiated through a search carried out in May 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”. The websites of Pordata and the National Institute of Statistics were also consulted. Content There are anatomical and physiological differences between genders, namely body size and shape, musculature and metabolism, which can modulate certain occupational issues, such as choosing and staying in certain jobs. Incidentally, in the same section of work, sometimes both genders take on different tasks and/or perform them in different ways. 98.8% of accidents in absolute numbers occur in males, as this is obviously much more prevalent in the industrial and construction sectors, areas where there is a higher accident rate. Discussion and Conclusions Accidents at work are more frequent and serious among men, not only due to the type of tasks that exist in positions predominantly assumed by this gender, but also due to the personality and influence of society and culture, which generally encourages more in this context to need to defy danger and/or be more acceptable not following the rules. Adherence to the proposed Safety measures varies with the Perception of Risk and the influence of the work team, management and society. As more of this global interference is taken into account, the greater the ability of the Occupational Health and Safety team to mitigate the incidence and severity of Occupational Accidents and thus obtain a safer workplace, and these measures must be different between the male and female sexes.

RESUMO Introdução/enquadramento/objetivos A generalidade dos profissionais a exercer na Saúde e Segurança Ocupacionais tem algumas noções relativas à distribuição dos Acidentes Laborais versus sexo, contudo, nem todos terão tido oportunidade de consultar dados razoavelmente atualizados sobre esse assunto.

Conteúdo Existem diferenças anátomo-fisiológicas entre os géneros, nomeadamente tamanho e formato corporal, musculatura e metabolização, que podem modular determinadas questões ocupacionais, como a escolha e permanência em alguns postos laborais. Aliás, na mesma secção de trabalho, por vezes os dois géneros assumem tarefas diferentes e/ou executam-nas de formas diversas. Em números absolutos, 98,8% dos acidentes ocorrem no sexo masculino, por este ser obviamente muito mais prevalente nos setores industrial e da construção, áreas essas onde existe uma maior sinistralidade. Discussão e Conclusões Os acidentes de trabalho são mais frequentes e graves no sexo masculino, não só devido ao tipo de tarefas que existem nos postos assumidos predominantemente por este género, mas também devido à personalidade e influência da sociedade e cultura que, geralmente, incentiva mais neste contexto a necessidade de desafiar o perigo e/ou ser mais aceitável não cumprir as regras. A adesão às medidas de Segurança propostas varia com a Perceção de Risco e a influência da equipa de trabalho, chefia e sociedade. Quanto mais esta globalidade de interferências for levada em conta, maior a capacidade da equipa de Saúde e Segurança Ocupacionais para atenuar a incidência e gravidade dos Acidentes Laborais e assim se obter um local de trabalho mais seguro, sendo que essas medidas deverão ser distintas entre os sexos masculino e feminino.

Abstract Objective: The aim of this study was to estimate whether the consumption of anticoagulants was associated with a difference in the frequency of thrombosis of any site, major bleeding and mortality, in adults with both diseases. Method: A retrospective cohort study was carried out in four high complexity centers. Patients older than 18 years with CKD on hemodialysis and non-valvular AF, with an indication for anticoagulation (CHA2DS2VASc ≥ 2), were included. The primary outcome was the occurrence of: major bleeding, thrombotic event (cerebrovascular accident, acute myocardial infarction or venous thromboembolic disease) or death. Adjustment for confounding variables was performed using logistic regression. Results: From 158 patients included, 61% (n = 97) received an anticoagulant. The main outcome was found in 84% of those who received anticoagulation and 70% of those who did not (OR: 2.12, 95%CI: 0.98-4.57; after the adjusted analysis OR: 2.13, 95%CI: 1.04-4.36). Separate outcomes were bleeding in 52% vs. 34% (OR: 2.03; 95%CI: 1.05-3.93), thrombosis in 35% vs. 34% (OR: 1.03; 95%CI: 0.52-2-01) and death in 46% vs. 41% (OR: 1.25; 95%CI: 0.65-2.38). Conclusions: The results of this study suggest an increased risk of bleeding in patients with AF and CKD on hemodialysis receiving anticoagulation, without a decrease in the risk of thrombotic events or all-cause mortality.

Resumen Objetivo: El objetivo de este estudio fue estimar si el uso de anticoagulantes se asociaba con una diferencia en la frecuencia de trombosis de cualquier sitio, hemorragia mayor y mortalidad en adultos con coexistencia de ambas patologías. Método: Se realizó un estudio de cohorte retrospectivo en cuatro centros de alta complejidad. Se incluyeron mayores de 18 años con ERC en hemodiálisis y FA no valvular, con indicación de anticoagulación (CHA2DS2VASc ≥ 2). El desenlace primario fue la ocurrencia de sangrado mayor, evento trombótico (accidente vascular cerebral, infarto agudo al miocardio o enfermedad tromboembólica venosa) o muerte. Se realizó ajuste por variables de confusión por regresión logística. Resultados: De los 158 pacientes incluidos, el 61% (n = 97) recibieron anticoagulante. El desenlace principal se encontró en el 84% de quienes recibieron anticoagulación y en el 70% de quienes no la recibieron (OR: 2.12, IC95%: 0.98-4.57; luego del ajuste OR: 2.13, IC95%: 1.04-4.36). De los desenlaces mayores se presentaron sangrado en el 52% vs. el 34% (OR: 2.03; IC95%: 1.05-3.93), trombosis en el 35% vs. el 34% (OR: 1.03; IC95%: 0.52-2.01) y muerte en el 46% vs. el 41% (OR: 1.25; IC95%: 0.65-2.38). Conclusiones: Los resultados de este estudio sugieren un incremento en el riesgo de sangrado en los pacientes con FA y ERC en hemodiálisis que reciben anticoagulación, sin disminución del riesgo de eventos trombóticos ni de muerte.

ABSTRACT After the X-rays discovery, there was a need to create radiopaque substances that would allow anatomical structures to be highlighted. Contrast media emerged to radiographically draw tubular or hollow structures such as the urinary excretory system. The purpose of this research is to describe the initial historical evolution of the contrast use in the urinary system as a tribute to the hundred years of its first feasible use in humans. For this, a historical research was carried out, theoretical and empirical methods were used that allowed the analysis of the historical trajectory of the development of iodinated contrast in urological studies. It was found that the initiators were Eduard Hascheck and Otto Lindenthal. Other scientists used contrast media in the urinary system with little value. In 1919, Carlos Heuser described its use in cystographies and ureterographies, but this was not taken into account. Berberich and Hirsch, in 1923, are leaders in performing intravenous pyelography without any accident. Several compounds were studied up to Uroselectan, a substance best adapted to urography. It is concluded that 1923 was taken as the beginning of contrasting studies on the urinary system; however, there were researches prior to it. It was not until 1930 that Uroselectan emerged, giving rise to the beginning of iodine for diagnostic purposes.

RESUMEN Luego del descubrimiento de los rayos X existió la necesidad de crear sustancias radiopacas que permitieran resaltar estructuras anatómicas. Surgieron los medios de contraste para dibujar radiográficamente estructuras tubulares o huecas como el sistema excretor urinario. El propósito de este trabajo es describir la evolución histórica inicial del uso de contraste en el sistema urinario como homenaje a los cien años de su primera utilización factible en humanos. Para ello se realizó una investigación de corte histórico, se emplearon métodos teóricos y empíricos que permitieron realizar el análisis de la trayectoria histórica del desarrollo del contraste yodado en estudios urológicos. Se constató que los iniciadores fueron Eduard Hascheck y Otto Lindenthal. Otros científicos utilizaron medios de contraste en el sistema urinario con escaso valor. En 1919, Carlos Heuser describió su uso en cistografías y ureterografías, pero esto no se tomó en cuenta. Berberich y Hirsch, en 1923, son referentes en realizar una pielografía intravenosa sin ningún accidente. Varios compuestos fueron estudiados hasta el Uroselectan, sustancia mejor adaptada a la urografía. Se concluye que el 1923 se tomó como el inicio de los estudios contrastados en el sistema urinario; sin embargo, existieron investigaciones anteriores a ella. No fue hasta 1930 que surge el Uroselectan, dando lugar al inicio del yodo con fines diagnósticos.
