Treatment of spinal cord injury with biomaterials and stem cell therapy in non-human primates and humans.

Spinal cord injury results in the loss of sensory, motor, and autonomic functions, which almost always produces permanent physical disability. Thus, in the search for more effective treatments than those already applied for years, which are not entirely efficient, researches have been able to demonstrate the potential of biological strategies using biomaterials to tissue manufacturing through bioengineering and stem cell therapy as a neuroregenerative approach, seeking to promote neuronal recovery after spinal cord injury. Each of these strategies has been developed and meticulously evaluated in several animal models with the aim of analyzing the potential of interventions for neuronal repair and, consequently, boosting functional recovery. Although the majority of experimental research has been conducted in rodents, there is increasing recognition of the importance, and need, of evaluating the safety and efficacy of these interventions in non-human primates before moving to clinical trials involving therapies potentially promising in humans. This article is a literature review from databases (PubMed, Science Direct, Elsevier, Scielo, Redalyc, Cochrane, and NCBI) from 10 years ago to date, using keywords (spinal cord injury, cell therapy, non-human primates, humans, and bioengineering in spinal cord injury). From 110 retrieved articles, after two selection rounds based on inclusion and exclusion criteria, 21 articles were analyzed. Thus, this review arises from the need to recognize the experimental therapeutic advances applied in non-human primates and even humans, aimed at deepening these strategies and identifying the advantages and influence of the results on extrapolation for clinical applicability in humans.

Perfil epidemiológico dos acidentes por material biológico em médicos da atenção primária em Minas Gerais, de 2012 a 2021 / Epidemiological profile of accidents involving biological material among primary health care physicians in Minas Gerais, from 2012 to 2021 / Perfil epidemiológico de accidentes por material biológico en médicos de atención primaria en Minas Gerais, de 2012 a 2021

Introdução: Os acidentes ocupacionais com material biológico representam um problema de saúde pública. A exposição ocupacional dos profissionais da saúde configura-se como um risco de transmissão de diversos patógenos. Na literatura, há carência de estudos que analisem o perfil dos acidentes com material biológico nos médicos da atenção primária. Objetivo: Buscou-se compreender o perfil epidemiológico dos acidentes com material biológico em médicos da atenção primária em Minas Gerais. Métodos: Estudo epidemiológico descritivo com análise do perfil dos acidentes com material biológico em médicos da atenção primária em Minas Gerais, utilizando dados secundários. Resultados: No período analisado, foram registrados 111 acidentes com material biológico, dos quais 54% ocorreram somente em 2020 e 2021. A maioria dos casos deu-se em mulheres (59%), e os tipos mais frequentes de exposição foram mucosa (38%) e percutânea (33%). Dos médicos, 23% não possuíam esquema vacinal contra a hepatite B completo. Em média, em 36% dos acidentes os testes sorológicos foram negativos e em 61% não foram realizados ou o campo foi ignorado/deixado em branco. Em apenas 7,2% dos casos a quimioprofilaxia foi indicada, mas ressaltam-se os registros ignorados ou em branco. Mais da metade dos acidentados não emitiu a Comunicação de Acidente de Trabalho (CAT). Conclusões: Os acidentes com material biológico predominam em médicas e nas formas de exposição mucosa e percutânea. Investimentos em medidas de biossegurança e educação permanente são necessários para prevenir casos e estimular sua notificação.

Introduction: Occupational accidents with biological material represent a public health problem. The occupational exposure of health professionals represents a risk of transmission of various pathogens. In the literature, there is a lack of studies that analyze the profile of accidents with biological material among primary health care physicians. Objective: We aimed to understand the epidemiological profile of accidents involving biological material among primary health care physicians in Minas Gerais, Brazil. Methods: Descriptive epidemiological study that analyzed the profile of accidents with biological material among primary health care doctors in Minas Gerais, using secondary data. Results: In the period analyzed, 111 accidents with biological material were recorded, of which 54% occurred only in 2020 and 2021. Most cases occurred in women (59%) and the most frequent types of exposure were mucosal (38%) and percutaneous (33%). About a quarter (23%) of physicians did not have a complete immunization record for hepatitis B. On average, in 36% of accidents serological tests were negative and in 61% they were not performed or the field was ignored/left blank. In only 7.2% of cases, chemoprophylaxis was indicated, but ignored or blank records stood out. More than half of the victims did not fill out a work accident report. Conclusions: Accidents with biological material predominate in female doctors and in forms of mucosal and percutaneous exposure. Investments in biosafety measures and permanent education are necessary to prevent cases and encourage their notification.

Empatia (parte I): contribuições para a abordagem centrada na pessoa / Empathy (part I): contributions to a person-centered approach / Empatía (parte I): contribuciones a un enfoque centrado en la persona

Introdução: Este artigo explora o tema da empatia na relação médico-paciente. Objetivo: Contribuir para o aperfeiçoamento das habilidades de comunicação clínica ao revisar o entendimento e a aplicação da empatia na prática clínica. Métodos: Trata-se de uma revisão não sistemática dos principais livros utilizados na comunicação clínica sobre o tema da empatia. O recorte metodológico compreendeu as seguintes etapas: (1) amostra intencional da literatura; (2) coleta e leitura de dados ­ i.e., extração de fragmentos dos textos; (3) análise do conteúdo, com o foco na definição, importância e instrumentalização para a aplicação prática; (4) seleção e síntese, para facilitar a compreensão e a contextualização sobre o tema; e (5) comparação e ponderação do conteúdo selecionado. Resultados: A abrangência com que a empatia foi trabalhada na literatura selecionada resultou em três níveis de densidade empática: baixa, moderada e alta. Assim, a baixa densidade empática limitou-se mais à definição e importância do tema; a densidade moderada incorporou algum exemplo de como aplicar a empatia, porém de forma fragmentada; e a alta densidade empática abordou o tema de modo mais completo, facilitando a instrumentalização na prática clínica. Há concordância na literatura analisada de que a prática da empatia reflete-se na melhoria do cuidado médico, entretanto seu exercício permanece no campo racional. Ao exemplificar a aplicação prática da empatia, os autores sugerem que o médico adote uma postura isenta de julgamentos, ao mesmo tempo que propõem um exercício imaginativo, de adivinhação dos sentimentos/emoções do paciente. Apesar de os autores de alta densidade empática compreenderem a importância das emoções e nomeá-las no processo, percebe-se a necessidade de um desdobramento e aprofundamento a partir desse ponto. Conclusões: Por se tratar de um assunto complexo, com vários matizes, a empatia é abordada de diferentes formas na literatura selecionada. Isso evidencia sua riqueza e originalidade, ao mesmo tempo que apresenta lacunas para sua aplicação na prática clínica.

Introduction: This article explores the theme of empathy in the doctor-patient relationship. Objective: To contribute to the improvement of clinical communication skills by reviewing the understanding and application of empathy in clinical practice. Methods: A non-systematic review of the main books used in clinical communication on the topic of empathy. The methodological approach consisted in the following steps: (1) An intentional sample of the literature; (2) Data collection and reading, i.e., extracting fragments from texts; (3) Content analysis, focusing on definition, importance and instrumentalization for practical application; (4) Selection and synthesis to facilitate understanding and contextualization on the topic; and (5) Comparison and ponderance of the selected content. Results: The scope within which empathy was worked on in the selected literature resulted in three levels of empathic density: low, moderate, and high. Thus, low empathic density was limited to definition and importance; moderate density incorporated some examples of how to apply empathy in a fragmented way; high empathic density addressed the topic more fully, facilitating instrumentation in clinical practice. There is agreement in the literature analyzed that the practice of empathy reflects on the improvement of medical care. However, its exercise remains in the rational field. By exemplifying the practical application of empathy, the authors suggest that the physician adopt a non-judgmental posture, while proposing an imaginative exercise of guessing the patient's feelings/emotions. Although high-density empathy authors understand the importance of emotions and name them in the process, there is a need for an unfolding and deepening from this point on. Conclusions: Empathy is a complex subject with several nuances and is approached in different ways in the selected literature. This evidences its richness and originality, at the same time that it presents gaps for the application of empathy in clinical practice.

Resultados: el alcance con el que se trabajó la empatía en la literatura seleccionada tuvo como resultado tres niveles de densidad empática: baja, moderada y alta. Así, la baja densidad empática se limitaba más a la definición y la importancia; densidad moderada, incorporó algún ejemplo de cómo aplicar la empatía, pero de manera fragmentada; alta densidad empática se acercó del tema de manera más completa, facilitando la instrumentación en la práctica clínica. Existe acuerdo en la literatura analizada en que la práctica de la empatía se refleja en la mejora de la atención médica. Sin embargo, su ejercicio queda en el campo racional. Al ejemplificar la aplicación práctica de la empatía, los autores sugieren que el médico adopte una postura no crítica, al tiempo que propone un ejercicio imaginativo de adivinar los sentimientos/emociones del paciente. Si bien los autores de alta densidad empática entienden la importancia de las emociones y las nombran en el proceso, existe la necesidad de un desdoblamiento y profundización a partir de este punto. Conclusiones: Por tratarse de un tema complejo y con varios matices, la empatía es abordada de diferentes maneras en la literatura seleccionada. Esto evidencia su riqueza y originalidad, al mismo tiempo que presenta vacíos para la aplicación de la empatía en la práctica clínica.

Crise global da atenção primária à saúde / Global crisis in primary health care / Crisis global de la atención primaria

Enquanto no Norte Global se discute uma crise na Atenção Primária à Saúde, a maioria dos países nunca chegou a constituir sistemas de saúde baseados propriamente numa atenção primária robusta. Nesse cenário, o Brasil apresenta uma tendência mais favorável, com conquistas importantes para a atenção primária e a medicina de família e comunidade nos últimos dez anos. Restam desafios a serem superados para que o Sistema Único de Saúde alcance níveis satisfatórios de acesso a seus serviços, com profissionais adequadamente formados e valorizados pela população.

While the Global North is discussing a crisis in primary health care, the majority of countries have never managed to establish health systems based on robust primary care. Brazil presents a more favorable trend, with important achievements for primary care and family practice over the last ten years. There are still challenges to be overcome so that the Unified Health System achieves satisfactory levels of access to its services, with professionals who are properly trained and valued by the public.

Mientras que en el Norte Global se habla de una crisis de la atención primaria, la mayoría de los países nunca han creado realmente sistemas sanitarios basados en una atención primaria robusta. Brasil, muestra una tendencia más favorable, con importantes logros para la atención primaria y la medicina familiar y comunitaria en los últimos diez años. Aún quedan retos por superar para que el Sistema Único de Salud alcance niveles satisfactorios de acceso a sus servicios, con profesionales debidamente formados y valorados por la población.

Acidente crotálico seguido por primeiro episódio psicótico: um folclore clínico / Rattlesnake bite accident followed by first psychotic episode: a clinical folklore / Accidente crotálico seguido de primer episodio psicótico: un folclore clínico

Introdução: Acidentes ofídicos são doenças negligenciadas e constituem uma parcela importante da morbidade de pessoas em idade produtiva que vivem em zonas rurais. A maior parte dos seus efeitos a curto prazo é amplamente conhecida, especialmente aqueles de natureza clínica; no entanto, ainda se observa lacuna importante do conhecimento das consequências a longo prazo de tais agravos, notadamente as de ordem psíquica. Este artigo relata um caso de adoecimento mental subsequente a um acidente crotálico e gera reflexões de âmbito cultural e fisiopatológico a respeito das sequelas de tais eventos. Apresentação do caso: Trata-se de adolescente residente no interior baiano que foi vítima de mordedura por cascavel e teve necessidade de hospitalização em unidade de terapia intensiva. Observou-se que, mesmo após melhora clínica, iniciou com sintomas psicóticos prodrômicos e progrediu para piora mental grave, que culminou em internação psiquiátrica e diagnóstico de esquizofrenia no decorrer dos meses seguintes. Conclusões: Nota-se, neste caso, correlação direta entre esses dois eventos; mas, em razão da escassez de trabalhos científicos que abordem tais questões, depreende-se que é preciso investigar e estudar com maior profundidade possíveis associações entre acidentes crotálicos e psicoses.

Introduction: Snakebites are neglected diseases and constitute an important part of the morbidity of working-age people who live in rural areas. Most of their short-term effects are widely known, especially those of a clinical nature; however, there is still an important gap in the knowledge of the long-term consequences of such injuries, notably those of a psychotic nature. This article aims to report a case of mental illness subsequent to a rattlesnake bite accident and generate cultural and pathophysiological reflections regarding the consequences of such events. Case presentation: An adolescent residing in the interior of the state of Bahia was bitten by a rattlesnake and required hospitalization in an intensive care unit. It was observed that even after clinical improvement, the case started with prodromal psychotic symptoms and progressed to severe mental deterioration that culminated in psychiatric hospitalization and diagnosis of schizophrenia over the following months. Conclusions: In this case, there was a direct correlation between these two events, but because of the scarcity of scientific works that address such issues, it is necessary to investigate and study in greater depth possible associations between snakebite accidents and psychoses.

Introducción: Las mordeduras de serpientes son enfermedades desatendidas y constituyen una parte importante de la morbilidad de las personas en edad laboral que viven en zonas rurales. La mayoría de sus efectos a corto plazo son ampliamente conocidos, especialmente los de carácter clínico; sin embargo, todavía existe un importante vacío en el conocimiento de las consecuencias a largo plazo de este tipo de lesiones, en particular las de carácter psíquico. Este artículo tiene como objetivo informar un caso de enfermedad mental posterior a un accidente crotálico y generar reflexiones culturales y fisiopatológicas sobre las consecuencias de tales eventos. Presentación del caso: Se trata de un adolescente residente en el interior de Bahía que fue mordido por una serpiente cascabel y requirió hospitalización en unidad de cuidados intensivos. Se observó que, aún después de la mejoría clínica, comenzó con síntomas psicóticos prodrómicos y progresó a un deterioro mental severo que culminó con hospitalización psiquiátrica y diagnóstico de esquizofrenia en los meses siguientes. Conclusiones: En este caso, existe una correlación directa entre estos dos eventos pero, debido a la escasez de trabajos científicos que aborden tales cuestiones, parece necesario investigar y estudiar con mayor profundidad posibles asociaciones entre accidentes crotálicos y psicosis.

Resumo Enquadramento: A generatividade tem sido associada à resiliência e à satisfação com a vida na velhice, incluindo entre a população lésbica, gay, bissexual e transgénero (LGBT+) mais velha. Objetivo: Analisar as propriedades psicométricas da Loyola Generativity Scale (LGS) e da Generative Behavior Checklist (GBC) para idosos espanhóis LGBT + (com mais de 50 anos). Metodologia: Foi realizado um estudo psicométrico com 141 idosos espanhóis LGBT+ com o objetivo de examinar a validade de construto (análise fatorial exploratória), a validade convergente e a fiabilidade (consistência interna) da LGS e da GBC. Resultados: Os métodos de análise paralela e a análise fatorial exploratória sugeriram um modelo de dois fatores para ambos os instrumentos com boa adequação da amostra. A LGS explicou 45,1% da variância e apresentou uma consistência interna de 0,78. O GBC explicou 41,76% da variância e apresentou uma consistência interna de 0,879. Foi encontrada uma correlação positiva e estatisticamente significativa entre a satisfação com a vida e as escalas generativas. Foi também observada uma correlação positiva e significativa (rs = 0,310) entre os dois instrumentos. Conclusão: Ambos os instrumentos demonstraram ser válidos e fiáveis para medir a generatividade em idosos espanhóis LGBT+.

Abstract Background: Generativity has been associated with resilience and life satisfaction in older age, including among lesbian, gay, bisexual, and transgender (LGBT+) older adults. Objective: To examine the psychometric properties of the Loyola Generativity Scale (LGS) and Generative Behavior Checklist (GBC) for Spanish LGBT+ older adults (over the age of 50). Methodology: A psychometric study was conducted with 141 Spanish LGBT+ older adults to examine the construct validity (exploratory factor analysis), convergent validity, and reliability (internal consistency) of the LGS and the GBC. Results: Parallel and exploratory factor analyses suggested a two-factor model with good sample adequacy for both scales. The LGS explained 45.1% of the variance and had an internal consistency of 0.78. The GBC explained 41.76 % of the variance and had an internal consistency of 0.879. A positive and statistically significant correlation was found between life satisfaction and the generative scales. A positive and significant correlation (rs = 0.310) was also observed between both instruments. Conclusion: Both instruments proved valid and reliable for measuring generativity in Spanish LGBT+ older adults.

Resumen Marco contextual: La generatividad se asocia con la resiliencia y la satisfacción con la vida en la vejez, incluidas las de las personas adultas lesbianas, gays, bisexuales y transexuales (LGBT+). Objetivo: Examinar las propiedades psicométricas de la Loyola Generativity Scale (LGS) y la Generative Behavior Checklist (GBC) en adultos mayores LGBT+ españoles (mayores de 50 años). Metodología: Estudio psicométrico con 141 adultos mayores LGBT+. Se analizó la validez de constructo (análisis factorial exploratorio), la validez convergente y la consistencia interna de cada escala. Resultado: Los análisis factoriales paralelos y exploratorios sugieren un modelo bifactorial para ambas escalas con una buena adecuación a la muestra. La LGS explica el 45,1% de la varianza y tiene una consistencia interna de 0,78. La GBC explica el 41,76% de la varianza y tiene una consistencia interna de 0,879. Se encontró una correlación positiva estadísticamente significativa entre la satisfacción con la vida y las escalas de generatividad. Las dos escalas mostraron una correlación positiva y significativa (rs = 0,310). Conclusión: Ambas escalas han demostrado ser válidas y fiables para medir la generatividad en adultos mayores LGBT+ españoles.

Tratamento integrado para correção do sorriso gengival: relato de caso / Integrated treatment for correction of gingival smile: case report

O sorriso gengival possui inúmeras causas, podendo acontecer por motivos esqueléticos, musculares ou por alteração no desenvolvimento dos tecidos de suporte. No entanto, na atualidade, a estética vermelha e a branca têm se apresentado completamente passíveis de transformações e com uma gama de procedimentos cirúrgicos ou não cirúrgicos para sanar as queixas dos pacientes. O objetivo geral deste trabalho é mostrar o poder que a odontologia tem frente às questões estéticas, como, por exemplo, a vergonha de sorrir por não se sentir confortável com os dentes curtos e com uma grande faixa de gengiva sendo exposta. O método utilizado foi um relato de caso. Que descreve todos os passos clínicos do tratamento de um paciente de 40 anos, que estava insatisfeita com o seu sorriso por apresentar erupção passiva alterada juntamente com hiperatividade do lábio superior. O plano de tratamento escolhido foi de realizar a cirurgia de aumento de coroa clínica estético, seguido de clareamento dentário e posteriormente um reposicionamento labial, com ajuda da toxina botulínica. Finalizando, para ajudar na cicatrização, o uso de laserterapia. O resultado de todo o processo cirúrgico envolvido neste trabalho, é satisfação do paciente, materializando o sonho deste, devolvendo segurança e espontaneidade ao sorrir. Pôde-se observar que através da combinação de técnicas cirúrgicas periodontais para tratar o sorriso gengival, obtém-se êxito tanto no sentido científico quanto no biológico, alcançando um sorriso esteticamente mais atrativo(AU)

Gummy smile has numerous causes, which can occur for skeletal or muscular reasons or due to changes in the development of supporting tissues. However, nowadays, the red and white aesthetics have been completely capable of transformation and with a range of surgical or non-surgical procedures to resolve patients' complaints. The general objective of this work is to show the power that dentistry has in the face of aesthetic issues, such as, for example, the shame of smiling due to not feeling comfortable with short teeth and a large strip of gum being exposed. The method used was a case report. Which describes all the clinical steps of the treatment of a 40-year-old patient, who was dissatisfied with her smile due to an altered passive eruption together with hyperactivity of the upper lip. The chosen treatment plan was to perform aesthetic clinical crown augmentation surgery, followed by tooth whitening and later lip repositioning, with the help of botulinum toxin. Finally, to help with healing, the use of laser therapy. The result of the entire surgical process involved in this work is patient satisfaction, materializing the patient's dream, restoring security and spontaneity when smiling. It was observed that through the combination of periodontal surgical techniques to treat gummy smile, success is achieved both in the scientific and biological sense, achieving a more aesthetically attractive smile(AU)

Acquisition of foods that make up the new basic food basket by low-income brazilian families in 2017-2018: socioeconomic and demographic distribution / Aquisição de alimentos que compõem a nova cesta básica pelas famílias brasileiras de baixa renda em 2017-18: distribuição socioeconômica e demográfica

In 2024, the Brazilian government promulgated a decree with new guidelines for the basic food basket, based on the Brazilian Dietary Guidelines. This study describes the acquisition of foods that make up the new basic basket by low-income families in Brazil, using data from the latest edition of the Household Budget Survey, conducted in 2017-18. The household food acquisitions of families with a per capita income of up to half a minimum wage were analyzed, both for the country as a whole and according to housing situation, region of the country, and race/skin color of the head of the family (n=13,706 households). The foods that make up the basket, identified according to Ordinance 966 of the Ministry of Social Development, represented 84.1% of the total calories acquired by low-income households. The food groups with the highest contributions to total calories were cereals (33.4%), sugars and oils/fats (21.3%), and meats and eggs (11.5%). Rice, corn and other grains, and beans represented 19.6% and 4.6% of total calories, respectively. Poultry and beef were the most consumed meats, representing 4.9% and 4.0% of the calories. Fruits contributed to 1.9%, and vegetables and greens to 0.7%. The caloric share of foods that make up the new basic basket was higher in rural areas (88.0%) and in the North (88.2%) and Northeast (85.9%) regions. There were no significant differences between race/skin color categories. Our data show that, in 2017-18, the foods that make up the new basic basket were the foundation of the diet of the poorest population, reinforcing the cultural feasibility of its implementation and the need for policies that ensure continuous access to these foods.

Em 2024, o governo brasileiro promulgou um decreto com novas diretrizes para a cesta básica de alimentos, baseadas no Guia Alimentar para a População Brasileira. Este estudo descreve a aquisição dos alimentos que compõem a nova cesta básica por famílias de baixa renda no Brasil, utilizando dados da última edição da Pesquisa de Orçamentos Familiares, realizada em 2017-8. Foram analisadas as aquisições domiciliares de alimentos das famílias com renda per capita de até meio salário-mínimo, no país como um todo e segundo situação de moradia, região do País e raça/cor da pele do chefe da família (n=13.706 domicílios). Os alimentos que compõem a cesta, identificados conforme a Portaria 966 do Ministério do Desenvolvimento Social, representaram 84,1% do total de calorias adquiridas pelos domicílios de baixa renda.

Clinical profile of Oropouche Fever in Bahia, Brazil: unexpected fatal cases / Perfil clínico de la fiebre de Oropouche en Bahía, Brasil: casos fatales inesperados

Oropouche virus (OROV) is an arbovirus transmitted to humans by mosquitoes, with the Culicoides paraensis mosquito species as its primary vector, causing Oropouche fever. Records of an outbreak in Brazil have so far been restricted to Central-North region of the country. However, an increase in the occurrence of cases of this disease has been observed in the state of Bahia, where the rapid spread of the OROV virus is configured as an outbreak in the South and East macro-regions of great concern for public health. This is a case-based study of acute OROV infection that led to the death of two young women without comorbidities amid an outbreak of the disease. The patient's biological samples were subjected to routine real-time PCR assays for the diagnosis of Oropouche fever and other pathologies. In addition, serological tests and metagenomics were performed during the laboratory investigation. This study shows the need for an active and efficient surveillance system to control the spread of this virus, as well as the importance of carrying out prospective studies to better clarify the natural history of this disease.

El virus Oropouche (OROV) es un arbovirus transmitido al ser humano por mosquitos, siendo el mosquito de la especie Culicoides paraensis su vector principal, causante de la fiebre de Oropouche. Los registros de un brote en Brasil hasta ahora se han restringido a la región Centro-Norte del país. Sin embargo, se ha observado un aumento en la ocurrencia de casos de esta enfermedad en el estado de Bahía, donde la rápida propagación del virus OROV se configura como un brote en las macrorregiones Sur y Este de gran preocupación para la salud pública. Se trata de un estudio de caso de infección aguda por OROV que provocó la muerte de dos mujeres jóvenes sin comorbilidades en medio de un brote de la enfermedad. Las muestras biológicas de la paciente fueron sometidas a ensayos rutinarios de PCR en tiempo real para el diagnóstico de la fiebre de Oropouche y otras patologías. Además, se realizaron pruebas serológicas y metagenómicas durante la investigación de laboratorio. Este estudio muestra la necesidad de un sistema de vigilancia activo y eficiente para controlar la propagación de este virus, así como la importancia de realizar estudios prospectivos para esclarecer mejor la historia natural de esta enfermedad.

Behavioral and physiological responses of Girardia tigrina exposed to polyethylene microplastics.

Microplastic particles appear in great abundance and variety in freshwater ecosystems across the globe, spanning lakes and rivers, with increasingly frequent exposure of aquatic organisms. Studies on the mechanisms of any effects of plastic particles are still scarce, particularly in relation to the regenerative capacity of biota, for which there is no established model organism; however, planaria have shown sensitivity for assessing these risks to the aquatic environment. Thus, the present study aimed to investigate the behavioral and regeneration responses of the freshwater planaria Girardia tigrina exposed to polyethylene (PE) microplastics (MPs) incorporated into their food source. The greatest effect was observed on planarian regeneration, which was manifested at 10 µg/mg liver. Planaria reproduction and fertility were affected at 50 µg/mg liver; however, planaria locomotion was not affected at the concentrations evaluated. Mid-infrared absorption spectroscopy (FT-IR) was used to identify the constituent polymers, and ingestion of the polyethylene microplastic by the planaria was confirmed by infrared spectroscopy. The results highlight the potential adverse effects of exposure to polyethylene microplastic and show that the reproductive behavior and regeneration of a freshwater organism can be indicators of toxicity resulting from environmental pollution.

Digested galactoglucomannan mitigates oxidative stress in human cells, restores gut bacterial diversity, and provides chemopreventive protection against colon cancer in rats.

Galactoglucomannan (GGM) is the predominant hemicellulose in coniferous trees, such as Norway spruce, and has been used as a multipurpose emulsifier in the food industry. In vitro digestion with a cellular antioxidant activity assay was performed to determine the bioaccessibility and antioxidant activity of phenolic compounds, and the behaviour of GGM on in vivo experimental assay against induced colon cancer. The results showed that digestion decreased the bioaccessibility and antioxidant capacity of phenolic compounds. Cellular analysis did not support these findings once an antioxidant effect was observed in human cell lines. GGM attenuated the initiation and progression of colon cancer, by reducing the foci of aberrant crypts in rats, and modified the intestinal bacterial microbiota (disrupting the balance between Firmicutes and Bacteroidetes phyla). Thus, GGM provided chemopreventive protection against the development of colon cancer and acted as an intracellular antioxidant agent.

A safe, effective and adaptable live-attenuated SARS-CoV-2 vaccine to reduce disease and transmission using one-to-stop genome modifications.

Approved vaccines are effective against severe COVID-19, but broader immunity is needed against new variants and transmission. Therefore, we developed genome-modified live-attenuated vaccines (LAV) by recoding the SARS-CoV-2 genome, including 'one-to-stop' (OTS) codons, disabling Nsp1 translational repression and removing ORF6, 7ab and 8 to boost host immune responses, as well as the spike polybasic cleavage site to optimize the safety profile. The resulting OTS-modified SARS-CoV-2 LAVs, designated as OTS-206 and OTS-228, are genetically stable and can be intranasally administered, while being adjustable and sustainable regarding the level of attenuation. OTS-228 exhibits an optimal safety profile in preclinical animal models, with no side effects or detectable transmission. A single-dose vaccination induces a sterilizing immunity in vivo against homologous WT SARS-CoV-2 challenge infection and a broad protection against Omicron BA.2, BA.5 and XBB.1.5, with reduced transmission. Finally, this promising LAV approach could be applicable to other emerging viruses.

Pre-harvest application of sodium nitroprusside enhances storage root quality in red beet cultivated under normal and drought conditions.

BACKGROUND: The role of nitric oxide (NO) in plant stress tolerance, as well as in increasing post-harvest quality, has been extensively demonstrated in several fruits and vegetable crops; however, the effects of its pre-harvest application on post-harvest quality are still poorly documented. Therefore, the pre-harvest application of NO in red beet (Beta vulgaris subsp. vulgaris) plants cultivated under well-watered and drought conditions was evaluated to assess whether it improves the post-harvest quality of their storage roots. Red beet plants cultivated under well-watered (80% of water holding capacity) or drought condition (15% of water holding capacity) were sprayed weekly with water (control) or 100 µmol L-1 sodium nitroprusside (SNP), an NO donor. Sixty-six days after sowing, red beet roots were harvested, and root yield, total sugar yield, reducing sugars, non-reducing sugars, proteins, lipids, root ashes, root moisture, soluble solids, titratable acidity, pH, vitamin C, total phenolics, total betalains, betacyanins, betaxanthins and antioxidant capacity were determined. RESULTS: While drought led to a reduction in root yield, sugars, lipids and titratable acidity, it increased phenolic compounds, betalains and the antioxidant capacity of beets. SNP reversed the negative effects of drought on sugar, lipid and organic acid contents and increased antioxidant capacity independent of stress. CONCLUSION: Pre-harvest SNP treatment reversed drought-induced yield reductions in beets, while boosting bioactive compounds and antioxidant capacity. It also enhanced vitamin C content independently, indicating its dual role in stress mitigation and beet quality improvement. Future research should explore other crops and stress conditions. © 2024 Society of Chemical Industry.

Addressing human factors in the recognition and management of local anaesthetic systemic toxicity.

In the perioperative environment, local anaesthetics are commonly administered to patients to provide analgesia and anaesthesia for a large range of surgical procedures. Although rare, their use can result in systemic toxicity, which is a life-threatening complication, underscoring the importance of early recognition and prompt management to mitigate patient risks. This article evaluates the impact of human factors and other aspects such as insufficient monitoring, errors in drug administration and poor adherence to safety protocols on the development and management of local anaesthetic systemic toxicity and provides practical considerations to minimise its occurrence.

Effects of vitamin D supplementation on metabolic syndrome parameters in patients with obesity or diabetes in Brazil, Europe, and the United States: A systematic review and meta-analysis.

Plasma 25-dihydroxyvitamin D levels appear reduced in patients with obesity or type 2 diabetes, as reported in several observational studies. However, the association between these reduced hormone levels and metabolic parameters is unclear. In any case, vitamin D supplementation in patients with Metabolic Syndrome is standard. Still, the impacts of this supplementation on conditions such as glycemia, blood pressure, and lipidemia are debatable. Based on this question, we carried out a systematic review and meta-analysis of randomized clinical trials in Brazil, Europe, and the United States that analyzed the effects of vitamin D supplementation on Metabolic Syndrome parameters in patients with obesity or type 2 diabetes. Our search yielded 519 articles and included 12 randomized controlled trials in the meta-analysis. Vitamin D supplementation had no effect on any of the outcomes analyzed (fasting blood glucose and insulinemia, glycated hemoglobin, HOMA index, systolic and diastolic blood pressure, weight, waist circumference, total cholesterol, LDL and HDL, and triglycerides). However, subgroup analyses indicated that using vitamin D up to 2000 IU daily reduced participants' fasting blood glucose and glycated hemoglobin. Furthermore, the intervention reduced diastolic blood pressure only in participants with vitamin D deficiency. At least two studies showed a high risk of bias using the Rob2 protocol. According to the GRADE protocol, the evidence quality varied from moderate to very low. These results indicate that vitamin D supplementation does not improve patients' metabolic parameters and that the association between plasma 25-dihydroxyvitamin D levels and Metabolic Syndrome may not be causal but caused by other confounding characteristics. However, in any case, the quality of evidence is still low, and more randomized clinical trials are essential to clarify these relationships.

Predicting immune checkpoint therapy response in three independent metastatic melanoma cohorts.

Introduction: While Immune checkpoint inhibition (ICI) therapy shows significant efficacy in metastatic melanoma, only about 50% respond, lacking reliable predictive methods. We introduce a panel of six proteins aimed at predicting response to ICI therapy. Methods: Evaluating previously reported proteins in two untreated melanoma cohorts, we used a published predictive model (EaSIeR score) to identify potential proteins distinguishing responders and non-responders. Results: Six proteins initially identified in the ICI cohort correlated with predicted response in the untreated cohort. Additionally, three proteins correlated with patient survival, both at the protein, and at the transcript levels, in an independent immunotherapy treated cohort. Discussion: Our study identifies predictive biomarkers across three melanoma cohorts, suggesting their use in therapeutic decision-making.

Age of obesity onset affects subcutaneous adipose tissue cellularity differently in the abdominal and femoral region.

OBJECTIVE: We aimed to examine the effect of age of obesity onset, sex, and their interaction on abdominal and femoral subcutaneous adipose tissue (SAT) morphology (degree of adipocyte hyperplasia or hypertrophy). METHODS: In this cross-sectional study, we isolated adipocytes via collagenase digestion from abdominal and femoral SAT biopsies taken from male and female adults with childhood-onset obesity (CO; n = 8 males, n = 16 females) or adult-onset obesity (AO; n = 8 males, n = 13 females). Regional body composition was measured with dual-energy x-ray absorptiometry and a single-slice abdominal computed tomography scan. Mean adipocyte size was measured in abdominal and femoral SAT and was used to quantify morphology in android and gynoid subcutaneous fat, respectively. RESULTS: Abdominal SAT morphology was more hyperplastic in females with CO than females with AO (p = 0.004) but did not differ between males with CO and males with AO (p = 0.996). Conversely, femoral SAT morphology was more hypertrophic in males and females with CO than those with AO. CONCLUSIONS: Age of obesity onset appears to affect SAT morphology differently in the abdominal and femoral regions of male and female adults. Our findings challenge the notion that SAT is uniformly hyperplastic in CO and hypertrophic in AO.
