Novel nanocomposites synthesized with pollen grain, as a precursor, were tested for CO2 adsorption performance. The pollen-derived carbons were obtained by direct calcination (PC), calcination followed by KOH-chemical activation (PCKOH), and MgO incorporation using high-energy ball-milling (PC-MgO and PCKOH-MgO). All the as-prepared materials were texturally, morphologically and structurally characterized by N2 physisorption, scanning electron microscopy (SEM-EDS) and X-ray diffraction (XRD); CO2 adsorption/desorption was measured by thermogravimetry. The four materials were able to adsorb CO2 at 30 ºC and 1 bar, but PCKOH-MgO, with the high surface area (12.4 m2 g-1), total pore volume of (0.13 cm3 g-1) and microporosity, was the best (2.06 mmol g-1 and percentage of adsorption (Qad) = 9.06%, at 1 bar). This result is due to the synergic effect of both synthesis methods. Neither temperature (from 30 to 100 ºC), nor pressure (from 1 to 15 bar), improved the adsorption process of PCKOH-MgO. CO2 desorption times at 300 ºC were 47 min for PCKOH-MgO and 30 min for the other adsorbents, showing the possibility of cycling. Based on the obtained results, the PCKOH-MgO activated carbon nanocomposite stands as a promising adsorbent to be potentially used for industrial CO2 capture applications and to contribute to long-term solutions to avoid dangerous climate-change and reduce CO2 emissions. grain precursor CO performance pollenderived derived PC, PC , (PC) KOHchemical KOH chemical PCKOH, PCKOH (PCKOH) highenergy energy ballmilling ball milling PCMgO PCKOHMgO.

The rapid advance of nanotechnology has led to the proliferation of a wide range of water-soluble nanomaterials and therefore, a profound impact on the environment, underscoring the need to devise effective methods for isolating and confining these nanomaterials. This study presents the development of a highly effective system capable of removing and storing gold nanoparticles in solution using modified resins with different linking groups, such as tris(2-aminoethyl) amine, 3-mercaptopropionic acid, 11-mercaptoundecanoic acid, and L-cysteine. The catalytic properties of the resins functionalized with the thiol group containing gold nanoparticles were evaluated, using the reduction of the nitro compounds (3,5-dinitrosalicylic acid, 4-nitroguaiacol and 4-nitroaniline) as model reaction. Solid-phase organic synthesis was employed to prepare the modified resins and their interaction with gold nanoparticles was characterized using infrared spectroscopy, thermogravimetric analysis, field emission scanning electron microscopy-energy dispersive spectroscopy, and X-ray photoelectron spectroscopy. The removal capacity of the resins was evaluated using ultraviolet-visible optical emission spectroscopy and inductively coupled plasma techniques. Ultraviolet-visible technique was suitable to assess the catalytic properties of the functionalized resins containing gold nanoparticles. It was determined that the functionalized resins showed remarkable capacity for complex gold nanoparticles, removing them from the solution. The most significant removal was with 11-mercaptoundecanoic acid. watersoluble water soluble therefore environment groups tris2aminoethyl trisaminoethyl tris 2 aminoethyl tris(2-aminoethyl amine 3mercaptopropionic mercaptopropionic 3 acid 11mercaptoundecanoic mercaptoundecanoic 11 Lcysteine.

Worldwide, millions of people suffer from neurological and psychiatric conditions, such as schizophrenia, depression, and neurodegenerative diseases. These conditions are often linked to hyperactivity of monoamine oxidase B (MAO-B) in the brain, and inhibiting this enzyme can reduce oxidative stress, stabilize neurotransmitter levels, and alleviate symptoms. In this context, a pharmacophoric model was created using PharmaGist with 31 hits extracted from BindingDB to enable a pharmacophoric-based search of potential MAO-B inhibitors in ZincPharmer’s chemical space, followed by the building of 10 conformers for each molecule in the software OMEGA, screening for structural and electrostatic similarity to safinamide using ROCS (Rapid overlay of chemical structures) and EON (Electrostatic similarity for lead-hopping), respectively. In addition, the molecular docking with Gold using the score function was performed to rank the ligands with the highest probabilities of affinity to MAO-B and then discriminate those with suitable physical chemical, pharmacokinetic, and toxicological features using the tools QikProp, SwissADME, and DEREK. Four potential ligands with selective MAO-B inhibitor properties were identified, which show promise as future therapeutic agents for MAO-B-related disorders.

ABSTRACT Purpose: To compare the refractive prediction error of Hill-radial basis function 3.0 with those of 3 conventional formulas and 11 combination methods in eyes with short axial lengths. Methods: The refractive prediction error was calculated using 4 formulas (Hoffer Q, SRK-T, Haigis, and Hill-RBF) and 11 combination methods (average of two or more methods). The absolute error was determined, and the proportion of eyes within 0.25-diopter (D) increments of absolute error was analyzed. Furthermore, the intraclass correlation coefficients of each method were computed to evaluate the agreement between target refractive error and postoperative spherical equivalent. Results: This study included 87 eyes. Based on the refractive prediction error findings, Hoffer Q formula exhibited the highest myopic errors, followed by SRK-T, Hill-RBF, and Haigis. Among all the methods, the Haigis and Hill-RBF combination yielded a mean refractive prediction error closest to zero. The SRK-T and Hill-RBF combination showed the lowest mean absolute error, whereas the Hoffer Q, SRK-T, and Haigis combination had the lowest median absolute error. Hill-radial basis function exhibited the highest intraclass correlation coefficient, whereas SRK-T showed the lowest. Haigis and Hill-RBF, as well as the combination of both, demonstrated the lowest proportion of refractive surprises (absolute error >1.00 D). Among the individual formulas, Hill-RBF had the highest success rate (absolute error ≤0.50 D). Moreover, among all the methods, the SRK-T and Hill-RBF combination exhibited the highest success rate. Conclusions: Hill-radial basis function showed accuracy comparable to or surpassing that of conventional formulas in eyes with short axial lengths. The use and integration of various formulas in cataract surgery for eyes with short axial lengths may help reduce the incidence of refractive surprises.

ABSTRACT Purpose: Although Brazil has a high prevalence of retinoblastoma, there is a lack of epidemiological data on the disease. Thus, in this study, we aimed to evaluate the epidemiological profile of patients diagnosed with retinoblastoma in the ophthalmology department of a pediatric tertiary referral hospital in Ceara, Brazil. Methods: A descriptive and cross-sectional study was conducted by retrospectively analyzing the clinical and socioeconomic data from the medical records of pediatric patients followed-up at the hospital between 2007 and 2021. Retinoblastoma was diagnosed on the basis of a fundoscopic or histopathologic examination. Results: The data of 105 patients were included in the study, and the mean patient age at the time of diagnosis was 1.7 years. Most of the patients were women (50.5%) and hailed from rural areas (57.4%), which was associated with a higher tumor stage. Of the 150 patients, 57.1% initially presented with leukocoria. Ocular hyperemia was associated with more advanced stages of retinoblastoma (p=0.004). Bilateral involvement was observed in 25.7% of the patients and at a significantly younger age (p=0.009). The presence of retinal detachment, vascularized lesions, and vitreous seeds significantly increased the likelihood of requiring enucleation. Discussion: This study presents an epidemiological description of retinoblastoma in Brazil, which highlights the significance of early detection. Delayed diagnosis is associated with a poorer visual prognosis and higher mortality rate, particularly in patients with unilateral disease. Risk factors for a more severe disease were retinal detachment, vascularized lesions, and vitreous seeds. The correlation between histopathological features and clinical outcomes was limited. Conclusion: Further studies are required to assess the influence of ocular hyperemia, fundoscopic assessment, and histopathologic findings on the prognosis of retinoblastoma. Moreover, it is critical to devise interventions to reduce the time-to-diagnosis in rural areas.

RESUMO Objetivo: Analisar a associação entre a participação em exercícios físicos relacionados ao fitness (EFRF) e a insatisfação com a imagem corporal (IIC) em adolescentes e avaliar a interação entre os exercícios físicos e o estado nutricional nesta associação. Métodos: Estudo transversal realizado em 2015 com 799 adolescentes (10 a 16 anos) de 14 escolas públicas de Curitiba (PR), Brasil. A IIC foi avaliada por meio do Body Shape Questionnaire e da Escala de Silhuetas. A participação em EFRF foi avaliada pelo Questionário de Atividade Física para Adolescentes e classificada em “não pratica”, “pratica ≤300 minutos/semana” e “pratica >300 minutos/semana”. As regressões de Poisson e logística multinomial, ajustadas por sexo, maturação sexual e estado nutricional, analisaram a associação entre EFRF e IIC. Resultados: A prevalência de IIC foi de 28,3%; 52,4% dos adolescentes queriam reduzir a silhueta e 48,7% não praticavam a EFRF. Adolescentes que praticavam EFRF >300 minutos/semana tiveram prevalência 28% maior para algum nível de IIC (razão de prevalência — RP 1,28; intervalo de confiança de 95% — IC95% 1,08–1,52) e chance 46% menor de querer reduzir silhuetas (OR 0,54; 95IC% 0,35–0,82), comparados aos não praticantes. Não houve interação entre os EFRF e o estado nutricional na associação com IIC. Conclusões: Os adolescentes que praticam EFRF >300 minutos/semana estão mais propensos a apresentar algum nível de IIC e têm menores chances de reportar o desejo de aumentar silhuetas, independentemente do estado nutricional.

ABSTRACT Objective: The aim of this study was to analyze the association between participation in fitness-related exercises (FRE) and body image dissatisfaction (BID) in adolescents and evaluate the interaction between physical exercise and nutritional status in this association. Methods: A cross-sectional study was conducted in 2015 involving 799 adolescents (10–16 years old) from 14 public schools in Curitiba (PR), Brazil. BID was assessed using the Body Shape Questionnaire and the Silhouette Scale. The FRE was classified as “does not practice,” “practices ≤300 min/week,” and “practices >300 min/week” by the Physical Activity Questionnaire for Adolescents. Poisson and multinomial logistic regressions, adjusted for sex, sexual maturation, and nutritional status analyzed the association of FRE and BID. Results: The BID prevalence was 28.3%; 52.4% of the adolescents wanted to reduce their silhouettes; and 48.7% did not practice FRE. Adolescents who practiced FRE >300 min/week had a 28% higher prevalence for some level of BID (PR 1.28; 95%CI 1.08–1.52) and a 46% lower chance of wanting to reduce silhouettes (OR 0.54; 95%CI 0.35–0.82), compared to nonpractitioners. There was no interaction between FRE and nutritional status in association with BID. Conclusions: The adolescents who practice FRE >300 min/week are likely to have some level of BID and are less likely to report the desire to increase their silhouettes, regardless of their nutritional status.

ABSTRACT Due to the important functions of calcium in plant physiology, supplementation of this nutrient may be a viable strategy to increase the tolerance of plants to salinity. Thus, the objective in this study was to evaluate the gas exchange and growth of broad-leaf arugula cultivars cultivated in coconut fiber subjected to salt stress. Four nutrient solutions [(S1 - standard nutrient solution (electrical conductivity of water - ECw of 0.5 dS m-1; S2 - nutrient solution using saline water with NaCl at 3.5 dS m-1; S3 - S2 enriched with Ca(NO3)2 at 50%; S4 - S2 enriched with Ca(NO3)2 at 100%, obtaining values of 2.3, 5.1, 5.5, and 5.9 dS m-1, for S1, S2, S3, and S4, respectively], and two cultivars of arugula (Donatella and Gigante Folha Larga), arranged in a 2 × 4 factorial scheme, with three replicates, were studied. Plants were harvested 40 days after sowing and evaluated for the following variables: plant height, number of leaves, leaf area, total fresh mass, total dry mass, specific leaf area, leaf succulence, relative chlorophyll index, stomatal conductance, CO2 assimilation rate, transpiration rate, internal CO2 concentration, instantaneous water use efficiency, and intrinsic carboxylation efficiency. The cultivar Gigante Folha Larga was more tolerant to salinity of nutrient solution. The use of salinized nutrient solution negatively affected arugula growth and physiology, but the extra addition of Ca(NO3)2 reduced the harmful effects of salinity. Extra addition of 50% of Ca(NO3)2 in the nutrient solution is recommended to reduce the effect of salt stress. physiology Thus broadleaf broad stress S1 S [(S electrical 05 0 5 0. m1 m 1 m-1 35 3 3.

RESUMO Devido às importantes funções do cálcio na fisiologia vegetal, a suplementação deste nutriente pode ser uma estratégia viável para aumentar a tolerância das plantas à salinidade. Assim, o objetivo deste estudo foi avaliar as trocas gasosas e o crescimento de cultivares de rúcula de folhas largas cultivadas em fibra de coco submetidas ao estresse salino. Quatro soluções nutritivas [(S1-solução nutritiva padrão (condutividade elétrica da água - CEa de 0,5 dS m-1; S2- solução nutritiva utilizando água salina com NaCl a 3,5 dS m-1; S3-S2 enriquecida com Ca(NO3)2 a 50%; S4-S2 enriquecido com Ca(NO3)2 a 100%, obtendo valores de 2,3, 5,1, 5,5 e 5,9 dS m-1, para S1, S2, S3 e S4, respectivamente], e duas cultivares de rúcula. (Donatella e Gigante Folha Larga), dispostas em esquema fatorial 2 × 4, com três repetições, foram estudadas. As plantas foram colhidas 40 dias após a semeadura e avaliadas quanto às seguintes variáveis: altura de planta, número de folhas, área foliar, massa fresca total, massa seca total, área foliar específica, suculência foliar, índice relativo de clorofila, condutância estomática, taxa de assimilação de CO2, taxa de transpiração, concentração interna de CO2 e eficiência instantânea do uso da água e eficiência intrínseca de carboxilação. A cultivar Gigante Folha Larga foi mais tolerante à salinidade da solução nutritiva. O uso de solução nutritiva salinizada afetou negativamente o crescimento e a fisiologia da rúcula, mas a adição extra de Ca(NO3)2 reduziu os efeitos nocivos da salinidade.

ABSTRACT Agribusiness workers are regularly exposed to high temperatures, even in covered environments such as packing houses. This study aimed to assess the effect of evaporative coolers on reducing occupational heat exposure for workers and consequently improving the thermal comfort of the selection and packaging areas in a table grape packing house. The evaluation was conducted as per the criteria of the Brazilian legislation, based on the Regulatory Norms (NR’s) 15 and 17 of the Department of Labor. The study was conducted during two climatic production periods, dry and rainy, with the evaporative coolers on and off. With the coolers on, the workers’ occupational exposure to heat was reduced without exceeding the wet bulb globe temperature index tolerance limit for the activities carried out according to the NR 15. However, it did not provide adequate thermal comfort indices according to NR 17. Under semiarid conditions, coolers rendered the environment thermally comfortable for local workers. To reduce the risks to workers’ health, it is suggested that they take breaks in case of discomfort from the heat and provide workers with water and mineral salts to replenish sweat loss. temperatures houses house legislation NRs s (NR’s 1 Labor periods rainy off However conditions health loss

RESUMO Os trabalhadores do agronegócio são expostos a condições de trabalho com altas temperaturas regularmente, mesmo em ambientes cobertos, como os packing houses. O objetivo deste estudo foi avaliar o efeito do uso de resfriadores evaporativos na redução da exposição ocupacional de trabalhadores ao calor e na melhoria do conforto térmico da área de seleção e embalagem de um packing house de uvas de mesa. A avaliação ocorreu de acordo com os critérios da legislação brasileira, aplicando-se as Normas Regulamentadoras (NR’s) 15 e 17, do Ministério do Trabalho. O estudo ocorreu durante dois períodos climáticos de produção: seco e chuvoso, com os resfriadores evaporativos ligados e desligados. Com os resfriadores evaporativos ligados, houve redução da exposição ocupacional dos trabalhadores ao calor, sem ultrapassar o limite de tolerância da temperatura de bulbo úmido para as atividades desenvolvidas, de acordo com a NR 15. Contudo, não apresentou índices adequados de conforto térmico, segundo a NR 17. Para as condições de semiárido, os resfriadores tornaram o ambiente termicamente confortável para os trabalhadores locais.

ABSTRACT Introduction: Burnout results from chronic exposure to work-related stress and it is characterized by a reduction in professional efficacy, feelings of lack of energy/exhaustion, and negativity related to work activities. It has a higher incidence in professions with significant interpersonal contact and among caregivers, making doctors a vulnerable population. The Maslach Burnout Inventory questionnaire is considered the gold standard for measuring this disease. In 2014, quinquennial prevention was described, aiming to prevent harm to patients through strategies that reduce Burnout in doctors. Clinical Case: The case describes a 29-year-old woman, a physician in her final year of Residency in General and Family Medicine, who sought an urgent consultation due to feelings of physical and mental exhaustion, hopelessness, irritability, initial and middle insomnia, for the last three months, and hyperphagia, two months ago. She has requested a sick leave from work because “I can't stand working anymore. I need to sleep for a week”. She identified excessive workload at the Clinic, stemming from the demands of her medical residency, as the main cause. She feels unsupported by her colleagues and Training Supervisor and feels pressured to manage the medical agenda without adequate preparation. She reports occasional errors in prescriptions, leading her to feel the need to repeatedly review records and decisions she has made. She denies any appointment with her designated Work physician ever since she started her internship. Upon physical examination, she appeared slaughtered, with a depressed mood, tearful, restless, and with fleeting eye contact. Applying the Maslach Burnout Inventory: Section A- 34 points- high level; Section B- 28 points- high level; Section C- 25 points- high level. A work leave from work was issued, laboratory studies were requested, and fluoxetine 20 mg and trazodone 50 mg were initiated, along with psychotherapy. So far, the patient has been re-evaluated in three consultations, with organic causes ruled out, and in the last re-evaluation, her scores were: Section A- 20 points- moderate level; Section B- 5 points- low level; Section C- 39 points- moderate level. She reports a decrease in medical errors. She maintained the prescribed medication and psychotherapy. She declined to join a Balint group. A new re-evaluation was scheduled in six months. Discussion/Conclusion: This is a case of a General and Family Medicine Resident Physician, diagnosed with Burnout, who has managed to substantially improve her quality of life and job satisfaction, as well as her personal life, following the implementation of both pharmacological and non-pharmacological measures, along with workplace adjustments and the setting of boundaries. She has successfully reduced her perception of making medical errors, thereby improving the quality of healthcare provided to the patients. The long journey of recovery from Burnout makes the monitoring of this illness imperative not only by the patients Family Doctor and Psychologist, but also by the Occupational physician, targeting the improvement of the quality of life of the healthcare professionals in their occupational activity. This clinical case’s purpose is to address and raise awareness among professionals to the prevention of Burnout, particularly in Residents, promoting quinquennial prevention. It is important to note that only professionals who are fulfilled in their biopsychosocial sphere can provide quality care and significantly reduce medical errors.

RESUMO Introdução: O Burnout resulta da exposição crónica ao stress laboral e caracteriza-se por redução da eficácia a nível profissional, sentimentos de falta de energia/exaustão e negatividade relacionados com a atividade laboral. Tem maior incidência em profissões de elevado contacto com pessoas e em prestadores de cuidados, tornando os médicos uma população vulnerável. O questionário Maslach Burnout Inventory é considerado gold standard para a medição desta patologia. Em 2014 foi descrita a prevenção quinquenária, que pretende evitar o dano para o paciente, atuando no médico através de estratégias que visem a diminuição do Burnout. Caso Clínico: Descreve-se uma mulher de 29 anos, médica, no último ano da especialização em Medicina Geral e Familiar, que recorreu a consulta aberta por sensação de exaustão física e mental, sentimentos de desesperança, irritabilidade, insónia inicial e intermédia, com três meses de evolução e hiperfagia há dois meses. Solicitou certificado de incapacidade temporária para o trabalho, porque “já não aguento mais trabalhar. Preciso de dormir uma semana”. Aponta como principal etiologia o trabalho excessivo no Centro de Saúde, decorrente da exigência do internato médico. Sente-se pouco apoiada pelos colegas de equipa e orientador de formação e considera-se pressionada a gerir a agenda médica sem ter preparação para tal. Relata erros pontuais na prescrição médica, pelo que sente necessidade de rever várias vezes os registos efetuados e as atitudes tomadas. Nega ter sido convocada para qualquer consulta de Medicina do Trabalho desde que ingressou na especialidade. Ao exame objetivo, apresentava-se cabisbaixa, com humor deprimido, chorosa, inquieta e com contacto ocular fugaz. Aplicando o questionário atrás mencionado: Secção A - 34 pontos - nível elevado; Secção B - 28 pontos - nível elevado; Secção C - 25 pontos - nível elevado. Foi emitido o certificado de incapacidade temporária para o trabalho, solicitado estudo analítico e iniciada fluoxetina 20mg e trazodona 50mg, bem como psicoterapia. Até à data, a doente foi reavaliada em três consultas, foi excluída patologia orgânica e na última reavaliação apresentava os seguintes valores: Secção A- 20 pontos- nível moderado; Secção B- 5 pontos- nível baixo; Secção C- 39 pontos- nível moderado. Refere diminuição dos erros médicos. Manteve a medicação instituída, bem como a psicoterapia. Recusou o grupo Balint. Foi programada nova reavaliação em seis meses. Discussão/Conclusão: Trata-se de uma doente, Médica Interna em Medicina Geral e Familiar com o diagnóstico de Burnout, que conseguiu melhorar substancialmente a sua qualidade de vida e satisfação no trabalho e vida pessoal, após a implementação de medidas farmacológicas e não farmacológicas e também após alterações a nível laboral e imposição de limites. Conseguiu diminuir a perceção de erro médico, melhorando assim os cuidados de saúde prestados aos utentes. O longo percurso de recuperação desta doença torna fulcral o acompanhamento destes utentes pela equipa de Medicina do Trabalho, e não só pelo Médico de Família e Psicólogo, visando melhorar a qualidade de vida e saúde dos profissionais no âmbito da sua atividade laboral. Com este caso clínico pretende-se abordar e sensibilizar os profissionais para a prevenção do Burnout, em particular nos médicos internos, fomentando a prevenção quinquenária. De ressalvar que apenas profissionais realizados na sua esfera biopsicossocial conseguem proporcionar cuidados de qualidade e reduzir de forma importante o erro médico.

ABSTRACT Agonoscena pistaciae (Hemiptera: Psyllidae) is a significant pest in pistachio (Pistacia vera L.) orchards in Türkiye. This study aimed to evaluate the effectiveness of yellow sticky traps as an alternative method for controlling A. pistaciae populations in pistachio orchards. Conducted in late September and early October of 2021 and 2022, during peak pest activity, the experiment was carried out in Siirt, with three replicates following a randomized block design. Five traps were hung on all sides of each tree for sampling. Repeated measures ANOVA (repeated measures; general linear model) was used to observe changes over time. The results indicated that yellow sticky traps were highly effective in mass trapping adults, capturing an average maximum of 12 332.67 adults per trap. A significant decrease in the number of nymphs and eggs on the leaves was observed in the yellow sticky trap-treated trees compared to the control plots by mid-October (P < 0.05). Specifically, the average number of nymphs per composite leaf dropped from 24.95 to 11.23 in 2021, and from 145.18 to 27.29 in 2022. Similarly, the average number of eggs per composite leaf decreased from 61.18 to 2.29 in 2021, and from 73.56 to 3.64 in 2022. These findings suggest that yellow sticky traps can significantly reduce psyllid populations in pistachio orchards over the long term and can be an effective control method when used early in the vegetative period for low- to medium-sized psyllid populations.

Resumen: Introducción: Las hospitalizaciones por Ambulatory Care Sensitive Conditions es un indicador que mide la utilización de los servicios hospitalarios por problemas de salud que podrían haber sido prevenidos en el primer nivel de atención. El concepto se refiere a los procesos en que la atención ambulatoria efectiva puede ayudar a disminuir los riesgos de hospitalización, en un segundo nivel de atención. El objetivo del estudio fue construir y validar una lista uruguaya de problemas de salud sensibles a cuidados ambulatorios (PSSCA) según CIE-10. Metodología: Para la construcción de la lista inicial de códigos de PSSCA se realizó una revisión de los listados existentes y se propuso un listado inicial que fue validado a través del Método Delphi. Se propone un listado de 99 códigos diagnósticos de PSSCA adaptado a nuestro entono sanitario. Los mismos permiten identificar y cuantificar problemas de salud que pueden producir hospitalizaciones potenciamente evitables mediante cuidados ambulatorios accesibes y oportunos en el primer nivel de atención. Resultados: Se conformó un panel de 12 expertos. A partir de los datos obtenidos, considerando los 99 diagnósticos clasificados por CIE-10, éstos se pueden subclasificar en función de si la patología es infecciosa o no, obteniendo un resultado general de 62 patologías en un total de 99 que pueden ser clasificadas como infecciosas, lo que se corresponde a un 62 %. Discusión: De la comparación de la lista uruguaya de PSSCA a la que hemos arribado y las listas validadas utilizadas para la construcción inicial del listado de patologías propuesto, podemos decir que la primera presenta un mayor porcentaje de coincidencia con la lista de patologías de Bello Horizonte. Podemos mencionar que la mayoría de los problemas de salud identificados con base en el listado de PSSCA, son sensibles de ser resueltos con la atención primaria oportuna y de calidad que podría evitar o disminuir de una manera significativa su hospitalización. Conclusiones: Este trabajo describe el proceso de construcción y validación de una lista de códigos de PSSCA adaptados al contexto uruguayo a través del método Delphi. Hemos arribado a un listado que comprende un total de 99 diagnósticos, agrupadas en un total de diecinueve categorías que considera la especificidad del contexto uruguayo del indicador.

Abstract: Introduction: Hospitalizations for Ambulatory Care Sensitive Conditions is an indicator that measures the use of hospital services for health problems that could have been prevented at the first level of care. The concept refers to the processes in which effective outpatient care can help reduce the risks of hospitalization, at a second level of care. The objective of the study was to build and validate a Uruguayan list of health problems sensitive to outpatient care (PSS-CA) according to ICD-10. Methodology: To construct the initial list of PSSCA codes, a review of the existing lists was carried out and an initial list was proposed that was validated through the Delphi Method. A list of 99 PSSCA diagnostic codes adapted to our healthcare environment is proposed. They make it possible to identify and quantify health problems that can lead to potentially avoidable hospitalizations through accessible and timely outpatient care at the first level of care. Results: A panel of 12 experts was formed. From the data obtained, considering the 99 diagnoses classified by ICD-10, these can be subclassified depending on whether the pathology is infectious or not, obtaining a general result of 62 pathologies in a total of 99 that can be classified as infectious, which corresponds to 62%. Discussion: From the comparison of the Uruguayan list of PSSCA that we have arrived at and the validated lists used for the initial construction of the proposed list of pathologies, we can say that the first presents a higher percentage of coincidence with the list of pathologies of Bello Horizonte . We can mention that most of the health problems identified based on the PSSCA list are sensitive to being resolved with timely and quality primary care that could prevent or significantly reduce hospitalization. Conclusions: This work describes the process of construction and validation of a list of PSSCA codes adapted to the Uruguayan context through the Delphi method. We have arrived at a list that includes a total of 99 diagnoses, grouped into a total of nineteen categories that consider the specificity of the Uruguayan context of the indicator.

Abstract The use of supplementary cementitious materials to replace Portland clinker is one of the most effective strategies adopted by cement companies to reduce CO 2 emission on large-scale. However, due to the limited availability of traditional materials, alternative options are being investigated. The main objective of this research is to evaluate the characteristics and effect of different replacement levels of cement by dregs and grits on compressive strength. The wastes were ground and particles smaller than 75 µm were used. Chemical and physical were performed to characterize the dregs and grits. For both wastes, replacement levels of 0, 5, 10, 20 and 30% of cement mass were evaluated in the mortar production. The water-cement ratio and superplasticizer admixture content were kept constant. In fresh state, the consistency index and incorporated air content were obtained. Mortars made with dregs had higher strength compared to grits due to the higher combined water content. The results showed that it is possible to replace up to 36% of cement with dregs to obtain a strength of 25 MPa; and 15% for 40 MPa. largescale. largescale large scale. scale large-scale However investigated 7 used 0 5 10 30 production watercement constant state obtained 36 MPa 15 4 1 3

Resumo Ouso de adições minerais em substituição ao clínquer Portland é uma das medidas mitigadoras de emissão de CO2, mais promissoras em larga escala, adotadas pelas cimenteiras. Dada a limitação de disponibilidade de algumas, materiais alternativos vêm sendo investigados. A presente pesquisa teve como objetivo caracterizar e avaliar o efeito de diferentes teores de dregs e grits em substituição parcial ao cimento na resistência à compressão. Os resíduos foram submetidos à moagem, utilizando-se partículas inferiores a 75 µm. Foram realizados ensaios para caracterização química e física dos dregs e grits. Para ambos os resíduos, foram analisados os teores de 0, 5, 10, 20 e 30% em substituição à massa de cimento na produção de argamassas. A relação água/finos e o teor de aditivo superplastificante foram mantidos constantes. No estado fresco, foram avaliados o índice de consistência e o teor de ar incorporado. As argamassas com dregs proporcionaram maior resistência em relação às com grits devido ao maior teor de água combinada. Os resultados mostraram que é possível substituir até 36% do cimento por esse resíduo para obtenção de resistência à compressão de 25 MPa e 15% para 40 MPa.
