Precast concrete products are load-tested to confirm compliance, but the workability of the concrete, being generally zero-slump concrete, is often not tested for quality control, as would be done with normal- or high-slump concrete. An industry practice in South Africa uses the percussive action of a rotary percussion drill to compact control cube samples. However, variability in specimen compaction leads to variations in the density and compressive strength results, making the procedure unreliable. This indicates a need for a simple, standardised quality control method for preparing zero-slump concrete cube samples with compaction equivalent to that achieved by precast machines. This technical note aims to (i) report on a practical and economical procedure (i.e. percussion-drill method) that has been formulated for quality control based on the concrete density achieved by precast machines, and (ii) apply this method to mix optimisation with the specific objective of partial replacement of the cement in a factory mix with a suitable fine filler to reduce cost and the carbon footprint of a precast facility. It was shown that the percussion-drill method was able to obtain reliable results (density, compressive strength) for quality control purposes and was successfully employed in the replacement of 17% to 32% of cement by volume with quartz flour in a factory mix. This resulted in a significant cost saving and a reduction in nett carbon emissions at the factory.

Abstract Different techniques have been described for fabricating obturators for patients with maxillary defects. The hollow bulb obturator has emerged as the treatment of choice in most patients due to its light weight, decreased stress on the underlying tissues, and decreased patient discomfort. This article presents a technique for fabricating a closed hollow bulb obturator using a laboratory scanner, computer- aided design software, and three-dimensional printing.

Resumo Várias técnicas foram descritas para a construção de obturadores para reabilitar os pacientes com defeitos maxilares. O obturador de bulbo oco é o tratamento de eleição na maioria dos pacientes devido ao seu baixo peso, reduzida carga nos tecidos subjacentes e menor desconforto para o paciente. Este artigo apresenta uma técnica para a obtenção de um obturador de bulbo oco fechado, usando um scanner de laboratório, um programa de desenho por computador e impressão 3D.

ABSTRACT Introduction: Diabetes mellitus is a public health issue affecting an increasing number of workers, representing a disease exacerbated by work with a high social, economic, and personal cost. The nature of the work performed, coupled with occupational risks in a hospital setting, significantly contribute to the disease's progression. This study aims to address the impact of this disease on work and the role of Occupational Health in the prevention of exposure to occupational risk factors in the hospital environment, which can contribute to the metabolic imbalance of type I diabetes mellitus. Methodology: The methodology included search in PubMed, Science Direct, and Google Scholar databases, using keywords such as "diabetes mellitus, occupational medicine, risk factors and occupational health”. Filters were applied, considering publications from 2010 to 2024, totaling 463 works. Exclusion criteria focused on non-diabetes-related diseases, exclusive focus on Type II, and non-occupational approaches. Articles on diabetes and occupational health and safety published in Revista Portuguesa de Saúde Ocupacional were also considered, in a total of five studies. Sources also included Direção Geral de Saúde Clinical Guidance, a national epidemiological study, and a technical manual on workplace diabetes, totaling 30 references in the discussion. Results: The authors report two cases of healthcare professionals from a hospital unit, both diagnosed with Type I Diabetes at the age of five. Case 1: A 35-year-old healthcare assistant with a history of depressive syndrome and recent diabetic retinopathy diagnosis. Case 2: A 57-year-old nurse with diabetic retinopathy, nephropathy, neuropathy, undergoing treatment for osteomyelitis of the right big toe, without cardiovascular changes. In both they work or have worked in shifts, including night shifts, engaging in physically demanding tasks. Discussion/Conclusion: Diabetes is a chronic disease requiring continuous medical care and patient education, alongside support in preventing acute complications and reducing the risk of chronic complications. The incidence of new Type I Dm cases is higher between 12-14 years. During the transition to adulthood and entry into the job market, patients face disease stigma, treatment management challenges, and psychosocial workplace-related issues. Implementing preventive measures and monitoring these workers should help reduce work absenteeism, productivity loss, and income loss for the worker.

RESUMO Introdução: A Diabetes mellitus é um problema de Saúde Pública que afeta um número crescente de trabalhadores. Pode ser considerada uma doença agravada pelo trabalho com um elevado custo social, económico e pessoal. O tipo de trabalho realizado e as exposições a riscos laborais em contexto hospitalar, podem contribuir para a sua progressão, segundo alguns autores. Este trabalho pretende abordar o impacto desta patologia no trabalho e o papel da Saúde Ocupacional na evicção da exposição a fatores de risco laborais, em ambiente hospitalar, que contribuem para o descontrolo metabólico da Diabetes Melitus tipo I. Pretende-se identificar as exposições laborais que podem constituir fatores de risco modificáveis, interferem com a aptidão para o trabalho, podem aumentar a frequência de acidentes laborais e acelerar a progressão crónica da doença. Metodologia: Na metodologia de pesquisa e seleção de estudos utilizou as bases de dados PubMed, Science Direct e Google Scholar, com as palavras-chave “diabetes mellitus, occupational medicine, risk factors, occupational health”. Aplicaram-se filtros de revisão e revisão sistemática, considerando publicações de 2010 a 2024, totalizando 463 trabalhos. Critérios de exclusão incidiram em doenças não relacionadas à diabetes, exclusividade na tipo II e abordagens não ocupacionais. Foram ainda considerados os artigos sobre diabetes e saúde e segurança no trabalho publicados na Revista Portuguesa de Saúde Ocupacional, num total de cinco estudos. Incluíram-se a Norma de Orientação Clínica da DGS, um estudo epidemiológico nacional e um caderno técnico sobre diabetes no local de trabalho, totalizando 30 fontes na discussão. Descrição dos casos: Os autores reportam dois casos de profissionais de saúde de uma unidade hospitalar, ambos com diagnóstico de Diabetes tipo I aos cinco anos de idade. Caso 1: Uma auxiliar de ação médica de 35 anos, com antecedentes pessoais de síndrome depressivo e diagnóstico recente de retinopatia diabética. Caso 2: Uma enfermeira de 57 anos com retinopatia e nefropatia diabética, neuropatia, em tratamento para uma osteomielite do 1º dedo do pé direito, sem alterações cardiovasculares. Ambas trabalham ou trabalharam por turnos, com trabalho noturno e com tarefas fisicamente exigentes. Discussão/Conclusão: A diabetes é uma doença crónica que requer cuidados médicos contínuos e educação do doente, juntamente com apoio na prevenção de complicações agudas e redução do risco de complicações crónicas. A incidência de novos casos de Dm tipo I é maior entre os 12-14 anos. Na transição para a idade adulta e entrada no mercado laboral, os doentes podem ser sujeitos ao estigma da doença, ter dificuldade na gestão do tratamento e/ou desafios psicossociais relacionados com o trabalho. A instituição de medidas preventivas e monitorização destes trabalhadores deverá ajudar a reduzir o absentismo laboral, a perda de produtividade e a perda de rendimento para o trabalhador.

Abstract Researchers from four countries conducted comparative research on the remote Education experience of Higher Education students during the Covid-19 pandemic and their return to face-to-face Education. Based on other research projects, we applied self-report questionnaires to convenience samples. This article focuses on the results for Portugal and Russia in relation to gender. Despite the differences between both countries, the findings point to the statistical predominance of women as well as their more positive attitudes toward remote Education. Factor analysis revealed that three factors converge to explain most of the variance: 1. Positive attitude in relation to remote Education, 2. Technical, psychological, and educational problems, 3. Positive attitude regarding the return to face-to-face Education. Although women have more access to Higher Education, they have lower occupational and income achievements than men.

ABSTRACT Brazil has the highest incidence of atmospheric discharges, on average of 77.8 million hitting the country yearly. Companies providing post-harvest services have a high monetary value concentrated in their predominantly metallic structures. Atmospheric discharge protection systems (ADPS) are used in this context to protect the facilities and people, composed of several elements that require visual inspection with a certain periodicity, an activity framed as working at height. This research aimed to establish a methodology for employing a Remotely Piloted Aircraft System (RPAS) in the visual analysis of the operational condition of external atmospheric discharge protection systems components located in grain storage structures to collect information during the preliminary risk analysis and planning of activities at height. A survey of the current literature related to the subject was carried out, in addition to the norms, inspection agencies, and operational prerequisites of this type of equipment in the national territory. Finally, a method was created and validated based on the inspection checklist with the main points for checking, which generates a score that represents the urgency level of intervention, applied in a unit located in western Paraná, Brazil, on 11/28/2022. This procedure eliminated the risk of workers falling during the planning and inspection stage of the structures, which helped the qualified professional to issue the technical inspection report more quickly. The disadvantage is related to the dependence on favorable weather conditions. discharges 778 77 8 77. yearly postharvest post harvest ADPS (ADPS people periodicity height RPAS (RPAS out norms agencies territory Finally checking intervention Paraná 11282022 11 28 2022 11/28/2022 quickly conditions 7 1128202 1 2 202 11/28/202 112820 20 11/28/20 11282 11/28/2 1128 11/28/ 112 11/28 11/2 11/

RESUMO O Brasil é o país com a maior incidência de descargas atmosféricas, em média 77,8 milhões atingem o país todos os anos. As empresas prestadoras de serviços pós-colheita possuem um elevado valor monetário concentrado em suas estruturas, que predominantemente são metálicas. Os sistemas de proteção contra descargas atmosféricas (SPDA) são utilizados neste contexto para realizar a proteção das instalações e pessoas, os quais são compostos por vários elementos que necessitam de inspeção visual com determinada periodicidade, atividade enquadrada como trabalho em altura. Esta pesquisa tem como objetivo estabelecer uma metodologia para o emprego de Remotely Piloted Aircraft System (RPAS) na análise visual das condições operacionais dos componentes de um sistema de proteção contra descargas atmosféricas externo, localizados em estruturas de armazenamento de grãos para coletar informações durante a análise preliminar de riscos e planejamento das atividades em altura. Realizou-se um levantamento da atual literatura relacionada ao assunto, além das normas, órgãos fiscalizadores e pré-requisitos operacionais deste tipo de equipamento em território nacional. Por fim, foi criado e validado um método com base no checklist de inspeção com os principais pontos para conferência, que gera uma pontuação que representa o nível de urgência de intervenção, aplicado em uma unidade localizada no oeste do Paraná, Brasil, em 28/11/2022. Este procedimento eliminou o risco de queda do trabalhador na etapa de planejamento e inspeção das estruturas, o que auxiliou o profissional habilitado a emitir o laudo técnico de vistoria com maior agilidade. A desvantagem relaciona-se à dependência das condições climáticas favoráveis. 778 77 8 77, anos póscolheita pós colheita metálicas SPDA (SPDA pessoas periodicidade altura RPAS (RPAS externo Realizouse Realizou se assunto normas prérequisitos pré requisitos nacional fim conferência intervenção Paraná 28112022 28 11 2022 28/11/2022 agilidade relacionase relaciona favoráveis 7 2811202 2 1 202 28/11/202 281120 20 28/11/20 28112 28/11/2 2811 28/11/ 281 28/11 28/1 28/

Resumo O impacto psicológico resultante da pandemia COVID-19 continua a ser investigado. Os profissionais de saúde (PS) enfrentam um risco acrescido de desenvolvimento de psicopatologia (p. ex. ansiedade, depressão, stress pós-traumático, e burnout) devido ao confronto com situações altamente desafiantes e potencialmente traumáticas. O presente estudo tem como objectivo avaliar os efeitos do GrowthCare (GWCA - um programa de intervenção em grupo), na promoção de crescimento pós-traumático (CPT). O GWCA conta com 7 sessões semanais de 60 minutos e visa diminuir o sofrimento psicológico e promover a saúde mental dos PS. O grupo psicoterapêutico (n=9) é misto (i.e., médicos, enfermeiros, assistentes técnicos) e foi avaliado em 2 momentos: inicial (T0) e final (T1), recorrendo aos instrumentos EADS-21, PCL-V, ICPT-21, MBI-HSS e 23-QVS. Os resultados sugerem que há diferenças estatisticamente significativas entre T0 e T1 no CPT (Z = 41; p = 0,028) e nos sintomas de depressão (Z = 2,5; p = 0,047), sendo que após a intervenção os participantes reportam mais CPT ([T0; M = 48,89; DP = 17,64]; [T1; M = 63,11; DP = 19,02]) e menos depressão ([T0; M = 3,56; DP = 4,10]; [T1; M = 2,44; DP = 3,71]). Conclui-se que o GWCA foi eficaz na promoção de CPT e na diminuição de sintomatologia depressiva.

Abstract The psychological impact resulting from the COVID-19 pandemic continues to be investigated. Healthcare professionals (HCWs) face an increased risk of developing psychopathology (e.g., anxiety, depression, post-traumatic stress, and burnout) due to being confronted with highly challenging and potentially traumatic situations. The present study aims to evaluate the effects of GrowthCare (GWCA - a group psychological intervention program), to facilitate posttraumatic growth (PTG). The GWCA has 7 weekly 60-minute sessions and aims to reduce psychological suffering and promote the mental health of HCWs. The psychotherapeutic group (n = 9) is mixed (i.e., doctors, nurses, technical assistants) and was evaluated in 2 moments: initial (T0) and final (T1), using the EADS-21, PCL-V, ICPT-21, MBI-HSS and 23-QVS instruments. The results suggest that there are statistically significant differences between T0 and T1 PTG (Z = 41, p = .028) and in depression symptoms (Z = 2.5, p = .047), and after intervention participants report more PTG ([T0; M = 48.89; SD = 17,64]; [T1; M = 63.11, SD = 19.02]) and less depression ([T0; M = 3.56, SD = 4.10]; [T1; M = 2.44, SD = 3.71]). In conclusion, the GWCA was effective facilitating PTG and reducing depressive symptoms.

ABSTRACT In patients with symptomatic severe aortic stenosis (SAS), who are at high surgical risk and who require transcatheter aortic valve implantation (TAVI), anatomic factors can determine if patients are suitable for this technique. A very large aortic annulus is a technical challenge given the limited options of adequate valve sizes, and, in most of them, using them in this type of patient is an off-label indication. We present the case of a 59-year-old man with symptomatic ASOS with surgical risk secondary to chronic liver damage referred for TAVI with an aortic annulus greater than 900 mm2. A Myval #32 valve was implanted with overexpansion without complications and early discharge.

RESUMEN Los pacientes con estenosis aórtica severa (EAoS) sintomática, de alto riesgo quirúrgico y que requieren un implante de válvula aórtica transcatéter (TAVI), el factor anatómico con un anillo valvular aórtico gigante es un desafío técnico dado que los tamaños de las válvulas percutáneas comercializadas son limitados para estas anatomías. Presentamos el caso de un hombre de 59 años, con EAoS sintomática con rechazo cardioquirúrgico secundario a daño hepático crónico. Es derivado para TAVI con un anillo aórtico mayor de 900 mm2. Se implantó una válvula Myval #32 con sobre expansión sin complicaciones y alta precoz.

Abstract In Mexico, it is not known which institutions use animals for scientific purposes. This work reports, based on data requested from the National Institute of Transparency, Access to Information and Protection of Personal Data (INAI by its acronym in Spanish), the types of institutions that use animals for research and how many of these have an ethics committee. Research centres, colleges, hospitals, national institutes, technical colleges, and public universities are the types of institutions that report using animals for experimentation. Only 54 % of institutions have ethics committees. Mexican institutions from 2015 to 2021 used a total of 2,112,786 animals. Mammals are the most widely used animal group. The scientific purposes for using animals depend on the type of institution that uses them. In Mexico, it is necessary to update the regulations in order to regulate the use, protection and the care of laboratory animals.

RESUMEN El Consorcio Europeo-Latinoamericano contra el Cáncer de Vesícula Biliar (CVB) EULAT Eradicate GBC está recopilando datos y muestras de alta calidad en cuatro países latinoamericanos con una alta incidencia de esta enfermedad: Argentina, Bolivia, Chile y Perú (www.SaludVesiculaBiliar.org). Los objetivos del consorcio incluyen la creación de un biorepositorio único integrado en una plataforma informática a medida, la identificación, validación y caracterización funcional de nuevos biomarcadores de riesgo del CVB, y el desarrollo de modelos predictivos que integren factores de riesgo tanto epidemiológicos como genético-moleculares. Para facilitar la recolección y la calidad de los datos sociodemográficos, clínicos, sobre las muestras, de estilo de vida y nutricionales de los 15.000 participantes latinoamericanos que están siendo reclutados, decidimos desarrollar la aplicación EULAT eCollect para reducir el tiempo invertido por los participantes en el estudio, limitar el uso de papel y tinta, minimizar los costes y errores asociados a la cumplimentación de formularios escritos y su posterior digitalización, automatizando además el monitoreo de las tasas de reclutamiento y de la calidad de los datos en cada centro participante. Este artículo describe el diseño e implementación de la aplicación EULAT eCollect, desde la especificación de los requisitos funcionales y no funcionales, hasta la implementación y validación de los cuatro módulos de la aplicación: I Entrevista sociodemográfica, II Información sobre las muestras, III Formulario de informe de casos y IV Cuestionario de hábitos alimenticios. Además de nuestra experiencia con el software Open Data Kit, presentamos resultados tanto generales como técnicos que pueden ser de interés para futuros proyectos de investigación, especialmente los estudios de prevención personalizada del cáncer llevados a cabo en regiones con niveles de ingreso bajos y medios.

ABSTRACT The European-Latin American Consortium towards Eradication of Preventable Gallbladder Cancer (GBC) - EULAT Eradicate CVB is collecting high-quality data and samples in four Latin American countries with a high incidence of GBC: Argentina, Bolivia, Chile and Peru. The goal is to build a unique biorepository integrated with a customized informatics platform, identify, validate, and functionally characterize novel GBC risk biomarkers, and develop GBC prediction models integrating epidemiological and genetic-molecular risk factors. We decided to develop the electronic data collection application EULAT eCollect to facilitate the retrieval of socio-demographic, clinical, lifestyle, nutritional, and sample information from the 15,000 Latin Americans we are enrolling. The EULAT eCollect app reduces the time spent by study participants, limits the use of paper and ink, minimizes the costs and errors associated with completing written forms and their subsequent digitization, and allows close monitoring of local recruitment rates and data quality. We describe in this article the design and implementation of EULAT eCollect, which started with the specification of functional and non-functional requirements and ended with the implementation and subsequent validation of the four application modules: I Socio-demographic interview, II Sample information, III Case report form, and IV Food frequency questionnaire. We present both general and technical results and our experience with the Open Data Kit software, which may be of interest for future research projects, especially those on personalized cancer prevention conducted in low- and middle-income regions.

Expanding uterine masses can be the cause of pregnancy loss and add technical difficulties to uterus evacuation due to the intense anatomical distortion of the endocervical canal and uterine cavity. The literature is scarce in the peculiarities of the management of missed abortions in uterus with important distorted anatomies. We report a case of a primigravida patient who presented a rapid and expressive increase of abdominal volume due to a giant uterine mass, evolving to miscarriage. Ultrasound can be a useful tool, allowing visualization of the endocervical path and uterine cavity, helping to perform uterine evacuation in the presence of anatomical distortion without compromising the reproductive future. To the best of our knowledge, no such case has been previously reported. cavity anatomies mass miscarriage tool future knowledge reported

Abstract Inspired by discussions in science and technology studies and ethnography in online contexts, I sought to describe how some sociotechnical associations occur in digital media. Based on the observation of content on an influencer’s profile on Instagram, I tried to create a field report that made visible not only the actions of the subjects, but also the different technical mediations that permeate these practices. I argue that these sociotechnical associations, with their human and machine agencies, constitute the work of content creators. The report is, above all, an experiment, an attempt to construct a less linear and anthropocentric narrative about what happens on social networks. I suggest that understanding these sociotechnical relationships tensions and can renew ethnographic practice. contexts media influencers influencer s Instagram subjects practices agencies creators is all experiment networks practice

Resumo Inspirada em discussões dos science and technology studies e sobre etnografia em contextos online, busquei descrever como se dão algumas associações sociotécnicas nas mídias digitais. A partir da observação de publicações no perfil de um influenciador no Instagram, procurei criar um relato de campo que visibilizasse não só a ação dos sujeitos, mas também as diferentes mediações técnicas que atravessam essas práticas. Argumento que essas associações sociotécnicas, com suas agências humanas e maquínicas, constituem o trabalho de criadores de conteúdo. O relato trata-se, sobretudo, de uma experimentação, uma tentativa na construção de uma narrativa menos linear e antropocêntrica sobre o que acontece nas redes sociais. Sugiro que compreender essas relações sociotécnicas tensiona e pode renovar a prática etnográfica. online digitais Instagram sujeitos práticas maquínicas conteúdo tratase, tratase trata se, trata-se sobretudo experimentação sociais etnográfica
