Soil colloids can significantly enhance spreading of polybromodiphenyl ethers in groundwater by serving as an effective carrier.

Polybromodiphenyl ethers (PBDEs), the widely used flame retardants, are common contaminants in surface soils at e-waste recycling sites. The association of PBDEs with soil colloids has been observed, indicating the potential risk to groundwater due to colloid-facilitated transport. However, the extent to which soil colloids may enhance the spreading of PBDEs in groundwater is largely unknown. Herein, we report the co-transport of decabromodiphenyl ester (BDE-209) and soil colloids in saturated porous media. The colloids released from a soil sample collected at an e-waste recycling site in Tianjin, China, contain high concentration of PBDEs, with BDE-209 being the most abundant conger (320 ± 30 mg/kg). The colloids exhibit relatively high mobility in saturated sand columns, under conditions commonly observed in groundwater environments. Notably, under all the tested conditions (i.e., varying flow velocity, pH, ionic species and ionic strength), the mass of eluted BDE-209 correlates linearly with that of eluted soil colloids, even though the mobility of the colloids varies markedly depending on the specific hydrodynamic and solution chemistry conditions involved. Additionally, the mass of BDE-209 retained in the columns also correlates strongly with the mass of retained colloids. Apparently, the PBDEs remain bound to soil colloids during transport in porous media. Findings in this study indicate that soil colloids may significantly promote the transport of PBDEs in groundwater by serving as an effective carrier. This might be the reason why the highly insoluble and adsorptive PBDEs are found in groundwater at some PBDE-contaminated sites.

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.

Invisibilização e preconceitos velados: barreiras para o acesso aos serviços de atenção básica pela população trans / Invisibilization and veiled prejudices: barriers to access to primary care services for the transgender population / Invisibilización y prejuicios velados: barreras para el acceso de la población trans a los servicios de atención primaria

Introdução: No processo de edificação da Política Nacional de Saúde Integral LGBT+, a Atenção Básica ganha importante destaque, pois deveria funcionar como o contato preferencial dos usuários transgênero (trans). Objetivo: Investigar quais as percepções dos profissionais da Atenção Básica quanto às situações de vulnerabilidade enfrentadas pelas pessoas trans, bem como pesquisar os impedimentos que eles consideram existir na busca dessa população por acesso a esses serviços. Métodos: Utilizou-se uma abordagem qualitativa por meio de entrevistas semiestruturadas com 38 profissionais de saúde atuantes das Estratégias Saúde da Família de dois municípios do interior do estado de São Paulo. O material obtido foi submetido à análise de conteúdo de Bardin. Resultados: Os resultados apontaram para o desconhecimento quanto aos reais empecilhos que dificultam o acesso e seguimento de pessoas trans nos serviços de saúde. Observou-se ainda a manutenção de preconceitos e ideias que reforçam estereótipos ligados ao tema e que se estendem ao exercício da profissão. Isso se relaciona diretamente com a falta da abordagem de assuntos relacionados à sexualidade humana na graduação desses profissionais, além da falta de atualização quanto ao tema, o que impacta a qualidade do serviço que é ofertado à população em estudo. Conclusões: As normativas e portarias já existentes precisam ser efetivamente postas em prática, fazendo-se imperativas a ampliação e difusão do conhecimento a respeito da temática trans no contexto dos serviços públicos de saúde, o que pode servir como base para subsidiar a formação dos profissionais que atuam nesse setor, bem como políticas públicas efetivas.

Introduction: In the process of creating the National LGBT+ Comprehensive Health Policy, primary care has important prominence as it must work as the preferential contact of transgender (trans) users. Objective: To investigate the perceptions of primary care professionals about the vulnerability situations faced by trans persons and also hindrances they consider existing in this population's search for access to these services. Methods: A qualitative approach was used through semi-structured interviews with 38 health care professionals working in the Family Health Strategy of two cities in the countryside of the state of São Paulo. The material obtained was submitted to analysis of Bardin content. Results: The results pointed to a lack of knowledge about real hindrances that obstruct the access to and follow-up by health services for trans persons. It was also observed the maintenance of prejudices and ideas that reinforce stereotypes connected to the matter and extend to the practice of professionals. It is directly related to the lack of approach of issues related to human sexuality in the education of those professionals, in addition to lack of update about it, which impacts the quality of service offered to the population under study. Conclusions: The standards and ordinances already existing need to be effectively practiced, being crucial the extension and spread of knowledge about trans matters in the context of public health services. It can be the basis for subsidizing the education of professionals who work in this field, as well as effective public policies.

El material obtenido fue sometido a análisis de contenido de Bardin. Resultados: Los resultados apuntaron al desconocimiento sobre los reales obstáculos que dificultan el acceso de personas trans a los servicios, además del segmento de los cuidados en las unidades. Se observó además que se mantienen los prejuicios e ideas que refuerzan estereotipos vinculados al tema y que se extienden al ejercicio de la profesión. Esto se relaciona directamente a la falta da abordaje de asuntos relacionados a la sexualidad humana en la graduación de estos profesionales, además de la falta de actualización sobre el tema, lo que impacta en la calidad del servicio que se ofrece a la población en estudio. Conclusiones: Las normas y ordenanzas ya existentes deben ser efectivamente puestas en práctica, por lo que es imperativo ampliar y difundir el conocimiento sobre la temática trans en el contexto de los servicios públicos de salud, que pueda servir de base para apoyar la formación de profesionales que actúan en este sector, así como políticas públicas efectivas.

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.

A importância dos cuidados paliativos exercidos por médicos de família e comunidade na Atenção Primária à Saúde: uma revisão narrativa / The importance of palliative care performed by family practice doctors in primary health care: a narrative review / La importancia de los cuidados paliativos realizados por médicos de familia y comunitario en la Atención Primaria de Salud: una revisión narrativa

Introdução: A terminalidade é uma situação cada vez mais vivenciada nos serviços de saúde em razão da progressão da expectativa de vida da população e, consequentemente, do incremento de pacientes com doenças crônicas graves. No Brasil, os serviços de cuidados paliativos ainda se encontram centralizados nos serviços de atenção terciária. Entretanto, em diversos países, a Atenção Primária à Saúde tem sido a grande prestadora e coordenadora de cuidados paliativos dos usuários, em prol da descentralização dessa assistência e da promoção do cuidado integral. Objetivo: Realizar uma revisão narrativa da literatura, a fim de identificar a relação dos médicos de família e comunidade na atuação de cuidados paliativos na Atenção Primária à Saúde. Métodos: Revisão bibliográfica por meio do acesso às bases de dados: Portal da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES), Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), Scientific Electronic Library Online (SciELO) e PubMed. Foram selecionados 16 artigos, os quais foram submetidos a análise temática e posterior discussão das principais características que colaboram para a maior atuação dos médicos de família e comunidade em cuidados paliativos. Resultados: Observou-se a importância da atuação dos médicos de família e comunidade em cuidados paliativos no âmbito da Atenção Primária à Saúde, bem como a interligação entre as duas especialidades, os desafios existentes nesse caminho e os benefícios dessa prática. Conclusões: A oferta de cuidados paliativos pelos médicos de família e comunidade na atenção primária favorece o acesso e acompanhamento dos pacientes. Entretanto, a atuação dos profissionais das Equipes de Saúde da Família nessa linha de cuidado ainda é insuficiente em razão da escassa capacitação na área.

Introduction: Terminality is a situation increasingly experienced in healthcare services due to the progression of the population's life expectancy and, consequently, the increase in patients with serious chronic diseases. In Brazil, Palliative Care services are still centralized in tertiary care services. However, in many countries, Primary Health Care has been the major provider and coordinator of Palliative Care for users, in favor of decentralizing this assistance and promoting comprehensive care. Objective: To carry out a narrative literature review to identify the relationship of Family Practice Doctors in the performance of Palliative Care in Primary Health Care. Methods: Bibliographic review through access to databases: CAPES, LILACS, SciELO, and PUBMED. Sixteen articles were selected, which were submitted to thematic analysis and subsequent discussion of the main characteristics that contribute to the greater performance of Family Practice Doctors in Palliative Care. Results: The importance of Family Practice Doctors in Palliative Care within the scope of Primary Health Care was observed, as well as the interconnection between the two specialties, the challenges along this path, and the benefits of this practice. Conclusions: The offer of Palliative Care by Family Practice Physicians in Primary Care favors the access and monitoring of patients. However, the performance of the professionals in Family Health Teams in this line of care is still insufficient due to the lack of training in the area.

Métodos: Revisión bibliográfica mediante acceso a bases de datos: Portal CAPES, LILACS, SciELO y PubMed. Fueron seleccionados dieciséis artículos, que fueron sometidos al análisis temático y posterior discusión de las principales características que contribuyen para una mayor actuación de los Médicos de Familia y Comunidad en Cuidados Paliativos. Resultados: Se constató la importancia del trabajo de los Médicos de Familia y Comunitarios en Cuidados Paliativos en el ámbito de la Atención Primaria de Salud, así como la interconexión entre las dos especialidades, los desafíos que existen en este camino y los beneficios de esta práctica. Conclusiones: La oferta de Cuidados Paliativos por Médicos de Familia y Comunitario en Atención Primaria favorece el acceso y seguimiento de los pacientes. Sin embargo, la actuación de los profesionales de los Equipos de Salud de la Familia en esta línea de atención aún es insuficiente debido a la falta de formación en el área.

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.

O (des)cuidado em saúde às pessoas LGBTQIAP+ dispensado por profissionais em unidades básicas de saúde / The (lack of)health care provided to LGBTQIAP+ people by professionals in primary care centers / El (des)cuidado en salud a las personas LGBTQIAP+ dispensado por profesionales en unidades básicas de salud

Objetivo: compreender o cuidado em saúde dispensado às pessoas LGBTQIAP+ por profissionais em Unidades Básicas de Saúde, a partir do referencial teórico da Política Nacional de Saúde LGBT (PNSILGBT) estabelecida pelo Sistema Único de Saúde (SUS). Método: estudo descritivo, com abordagem qualitativa, que entrevistou 12 profissionais de saúde da Atenção Básica. Os dados coletados passaram pela Análise Lexical utilizando-se do software IRAMUTEQ. Resultados: emergiram três categorias temáticas que possibilitaram compreender que os profissionais reconhecem as violências praticadas na assistência a essa população, as barreiras no acesso e as dificuldades enfrentadas por pessoas LGBTQIAP+. Considerações finais: o desconhecimento das políticas e a não percepção das consequências dessas ações para a saúde dessa população remete muito mais ao (des)cuidado do que efetivamente ao cuidado condizente as suas reais necessidades em saúde.

Objective: to understand the health care provided to LGBTQIAP+ people by professionals in Primary Care Centers, based on the theoretical framework of the National LGBT Health Policy (PNSILGBT) established by the Unified Health System (SUS). Method: a descriptive study with a qualitative approach, which interviewed 12 primary care health professionals. The data collected was subjected to Lexical Analysis using the IRAMUTEQ software. Results: Three thematic categories emerged which made it possible to understand that professionals recognize the violence practiced in assisting this population, the barriers to access and the difficulties faced by LGBTQIAP+ people. Final considerations: the lack of knowledge of the policies and the lack of perception of the consequences of these actions for the health of this population leads much more to (lack of)care than to care in line with their real health needs.

Objetivo: comprender el cuidado en salud brindado a las personas LGBTQIAP+ por profesionales en Unidades Básicas de Salud, partiendo del marco teórico de la Política Nacional de Salud LGBT (PNSILGBT) establecida por el Sistema Único de Salud (SUS). Método: estudio descriptivo, con enfoque cualitativo, que entrevistó a 12 profesionales de salud de la Atención Básica. Los datos recogidos fueron analizados mediante Análisis Léxico utilizando el software IRAMUTEQ. Resultados: surgieron tres categorías temáticas que permitieron comprender que los profesionales reconocen las violencias ejercidas en la asistencia a esta población, las barreras en el acceso y las dificultades enfrentadas por personas LGBTQIAP+. Consideraciones finales: el desconocimiento de las políticas y la no percepción de las consecuencias de estas acciones para la salud de esta población reflejan mucho más el (des)cuido que efectivamente el cuidado acorde a sus reales necesidades en salud.

Bone aluminum accumulation in the current era / Acúmulo de alumínio no tecido ósseo na era atual

In the last few years, evidence from the Brazilian Registry of Bone Biopsy (REBRABO) has pointed out a high incidence of aluminum (Al) accumulation in the bones of patients with CKD under dialysis. This surprising finding does not appear to be merely a passive metal accumulation, as prospective data from REBRABO suggest that the presence of Al in bone may be independently associated with major adverse cardiovascular events. This information contrasts with the perception of epidemiologic control of this condition around the world. In this opinion paper, we discussed why the diagnosis of Al accumulation in bone is not reported in other parts of the world. We also discuss a range of possibilities to understand why bone Al accumulation still occurs, not as a classical syndrome with systemic signs of intoxication, as occurred it has in the past.

Nos últimos anos, evidências do Registro Brasileiro de Biópsia óssea (REBRABO) apontaram uma alta incidência de intoxicação por alumínio (Al) no tecido ósseo de pacientes com DRC em diálise. Essa surpreendente informação parece representar não apenas um acúmulo passivo deste metal, visto que dados prospectivos do REBRABO sugerem que a presença de Al no tecido ósseo pode estar independentemente relacionada a eventos cardiovasculares adversos maiores. Essas informações contrastam com a percepção mundial do controle epidemiológico dessa condição. Neste artigo de opinião, discutimos por que o diagnóstico de acúmulo ósseo de Al não é relatado em outras partes do mundo, e também discutimos uma gama de possibilidades para entender por que nós acreditamos que o acúmulo de Al no tecido ósseo ainda ocorre, não como se apresentava no passado, ou seja, como uma síndrome com sinais e sintomas sistêmicos de intoxicação.

Analysis of neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios as inflammatory biomarkers in chronic kidney disease: impact of parathyroidectomy / Análise das relações neutrófilo/linfócito e plaqueta/linfócito como marcadores inflamatórios na doença renal crônica: impacto da paratireoidectomia

Abstract Introduction: Secondary hyperparathyroidism (SHPT) is one of the causes for inflammation in CKD. We assessed the impact of parathyroidectomy (PTX) on neutrophil-to-lymphocyte (N/L) and platelet-to-lymphocyte (P/L) ratios in SHPT patients. Methods: A total of 118 patients [hemodialysis (HD, n = 81), and transplant recipients (TX, n = 37)] undergoing PTX between 2015 and 2021 were analyzed. Results: There was a significant reduction in calcium and PTH levels in both groups, in addition to an increase in vitamin D. In the HD group, PTX did not alter N/L and P/L ratios. In the TX group, there was a reduction in N/L and P/L ratios followed by a significant increase in total lymphocyte count. Conclusion: N/L and P/L ratios are not reliable biomarkers of inflammation in SHPT patients undergoing PTX. Uremia, which induces a state of chronic inflammation in dialysis patients, and the use of immunosuppression in kidney transplant recipients are some of the confounding factors that prevent the use of this tool in clinical practice.

Resumo Introdução: O hiperparatireoidismo secundário (HPTS) é uma das causas de inflamação na DRC. Avaliamos o impacto da paratireoidectomia (PTX) nas relações neutrófilo/linfócito (N/L) e plaqueta/linfócito (P/L) em pacientes com HPTS. Métodos: Foram analisados 118 pacientes [hemodiálise (HD, n = 81) e transplantados (TX, n = 37)] submetidos à PTX entre 2015 e 2021. Resultados: Houve redução significativa de cálcio e PTH nos dois grupos, além de elevação de vitamina D. No grupo HD, a PTX não mudou as relações N/L e P/L. Já no grupo TX, houve redução nas relações N/L e P/L acompanhadas de elevação significativa do número de linfócitos totais. Conclusão: As relações N/L e P/L não são marcadores fidedignos de inflamação em pacientes com HPTS submetidos à PTX. A uremia, que induz um estado de inflamação crônica em pacientes dialíticos, e o uso de imunossupressão em pacientes transplantados renais são alguns dos fatores de confusão que impedem o uso dessa ferramenta na prática clínica.

Unraveling genetic, compositional, and organoleptic traits of elephant garlic of different geographical origins.

The ancient native variety of elephant garlic, known as "Aglione della Valdichiana" and cultivated in the Valdichiana area of Tuscany, Italy, has gained recent recognition in the National Catalog of Local Varieties. The renewed interest in traditional products has led to a focus on identifying local varieties of elephant garlic, driven by their distinctive organoleptic and nutritional characteristics. However, other types of elephant garlic nowadays available on the market appear similar, but challenges exist in discerning their origin and composition. This study focused on characterizing elephant garlic from Lazio, Italy, and the Val di Chiana region through genetic, chemical, and aromatic analyses to understand genetic and geographic influences. ISSR markers differentiated elephant garlic from common varieties and highlighted regional genetic diversity. Chemical analysis revealed higher polyphenol content and antioxidant activity in elephant garlic compared to common garlic.

The e-commerce landscape is evolving rapidly, and businesses seek novel ways to enhance their competitive edge. In this context, understanding consumers' purchase intentions becomes crucial. Drawing from the Stimulus-Organism-Response (SOR) theory, we propose a conceptual framework investigating the factors influencing purchase intention in e-commerce live-streaming marketing. The research adopts Structural Equation Modeling (SEM), Confirmatory Factor Analysis (CFA), and hypothesis testing to evaluate the relationships. The findings revealed that the attributes of live streaming, including the live streamer, the product, and the field, as well as trust and impulsiveness, positively influence purchase intention. This study provides a novel perspective on live streaming e-commerce with evidence on how e-commerce live streaming drives purchase intentions, enriches the content of live streaming e-commerce literature, and explores the practical implications for marketing managers who are looking for marketing by live streaming.

Luoshi Neiyi Prescription inhibits estradiol synthesis and inflammation in endometriosis through the HIF1A/EZH2/SF-1 pathway.

ETHNOPHARMACOLOGICAL RELEVANCE: Endometriosis (EMS) is a common gynecological disease that causes dysmenorrhea, chronic pelvic pain and infertility. Luoshi Neiyi Prescription (LSNYP), a traditional Chinese medicine (TCM) formula, is used to relieve EMS in the clinic. AIMS: This study aimed to examine the active components of LSNYP and the possible mechanism involved in its treatment of EMS. MATERIALS AND METHODS: Ultrahigh-performance liquid chromatography quadrupole time-of-flight mass spectrometry (UPLC-Q/TOF-MS) was used to identify the chemical components of LSNYP. Human primary ectopic endometrial stromal cells (ecESCs) and eutopic endometrial stromal cells (euESCs) were isolated, and the expression levels of hypoxia inducible factor 1A (HIF1A), enhancer of zeste homolog 2 (EZH2) and steroidogenic factor 1 (SF-1) were detected by immunofluorescence and qPCR. Cobalt chloride (CoCl2) was utilized to construct an in vitro hypoxic environment, and lentiviruses were engineered to downregulate HIF1A and EZH2 and upregulate EZH2. Subsequently, the expression levels of HIF1A, EZH2, and SF-1 were measured using qPCR or western blotting. The binding of EZH2 to the SF-1 locus in ESCs was examined via ChIP. Furthermore, the effects of LSNYP on the HIF1A/EZH2/SF-1 pathway were evaluated both in vitro and in vivo. RESULTS: A total of 185 components were identified in LSNYP. The protein and gene expression levels of HIF1A and SF-1 were increased, whereas those of EZH2 were decreased in ecESCs. After treating euESCs with 50 µmol·L-1 CoCl2 for 24 h, cell viability and estradiol (E2) production were enhanced. Hypoxia decreased EZH2 protein expression, while si-HIF1A increased it. SF-1 was increased when EZH2 was downregulated in normal and hypoxic environments, whereas the overexpression of EZH2 led to a decrease in SF-1 expression. ChIP revealed that hypoxia reduced EZH2 binding to the SF-1 locus in euESCs. In vitro, LSNYP-containing serum decreased E2 and prostaglandin E2 (PGE2) production, inhibited cell proliferation and invasion, and reduced the expression of HIF1A, SF-1, steroidogenic acute regulatory protein (StAR), and aromatase cytochrome P450 (P450arom). In vivo, LSNYP suppressed inflammation and adhesion and inhibited the HIF1A/EZH2/SF-1 pathway in endometriotic tissues. CONCLUSIONS: LSNYP may exert pharmacological effects on EMS by inhibiting E2 synthesis and inflammation through regulation of the HIF1A/EZH2/SF-1 pathway. These results suggest that LSNYP may be a promising candidate for the treatment of EMS.

SMEK1 promotes clear cell Renal Cell Carcinoma progression via EGFR tyrosine-kinase dependent pathway.

Studying the mechanisms underlying clear cell renal cell carcinoma (ccRCC), the most common subtype of kidney cancer, may address an unmet need in ccRCC-targeted drug research. Growing evidences indicate that protein phosphatase 4 (PP4) plays an important role in cancer biology. Here, we characterized the upregulation of PP4 core component SMEK1 in ccRCC using tissue microarrays and revealed that its high expression is closely associated with reduced patient survival. We then conducted cell function experiments and animal experiments to prove the tumor-promoting effect of SMEK1. Next, RNA-seq was performed to explore its underlying mechanism, and the results revealed that SMEK1-regulated genes were extensively involved in cell motility, and the canonical tyrosine kinase receptor EGFR was one of its targets. Moreover, we verified the regulatory effect of SMEK1 on EGFR and its downstream MAPK and AKT pathway through molecular experiments, in which erlotinib, a tyrosine kinase inhibitor, can partially block this regulation, demonstrating that SMEK1 mediates its effects dependent on the tyrosine kinase activity of EGFR. Mechanistically, SMEK1 bond to PRMT5 and facilitated PRMT5-mediated histone methylation to promote the transcription of EGFR. Furthermore, we studied the upstream regulators of SMEK1 and demonstrated that the transcription factor E2F1 could directly bind to the SMEK1 promoter by chromatin immunoprecipitation. Functionally, E2F1 could also induce ccRCC progression by manipulating the expression of SMEK1. Collectively, our findings demonstrate the overexpression of SMEK1 in ccRCC, and reveal a novel E2F1/SMEK1/PRMT5/EGFR-tyrosine-kinase-dependent pathway for ccRCC progression.

Is HLA-E with its receptors an immune checkpoint or an antigenic determinant in allo-HCT?

Hematopoietic cell transplantation (HCT) represents a potentially curative therapeutic approach for various hematologic and non-hematologic malignancies. Human leukocyte antigen (HLA) matching is still the central selection criterion for HCT donors. Nevertheless, post-transplant complications, in particular graft-versus-host disease (GvHD), relapse of disease and infectious complications, represent a major challenge and contribute significantly to morbidity and mortality. Recently, non-classical HLA class I molecules, especially HLA-E, have gained increasing attention in the context of allogeneic HCT. This review aims to summarize the latest findings on the immunomodulatory role of HLA-E, which serves as a ligand for receptors of the innate and adaptive immune system. In particular, we aim to elucidate how (i) polymorphisms within HLA-E, (ii) the NKG2A/C axis and (iii) the repertoire of peptides presented by HLA-E jointly influence the functionality of immune effector cells. Understanding this intricate network of interactions is crucial as it significantly affects NK and T cell responses and thus clinical outcomes after HCT.

NatB Protects Procaspase-8 from UBR4-Mediated Degradation and Is Required for Full Induction of the Extrinsic Apoptosis Pathway.

N-terminal acetyltransferase B (NatB) is a major contributor to the N-terminal acetylome and is implicated in several key cellular processes including apoptosis and proteostasis. However, the molecular mechanisms linking NatB-mediated N-terminal acetylation to apoptosis and its relationship with protein homeostasis remain elusive. In this study, we generated mouse embryonic fibroblasts (MEFs) with an inactivated catalytic subunit of NatB (Naa20-/-) to investigate the impact of NatB deficiency on apoptosis regulation. Through quantitative N-terminomics, label-free quantification, and targeted proteomics, we demonstrated that NatB does not influence the proteostasis of all its substrates. Instead, our focus on putative NatB-dependent apoptotic factors revealed that NatB serves as a protective shield against UBR4 and UBR1 Arg/N-recognin-mediated degradation. Notably, Naa20-/- MEFs exhibited reduced responsiveness to an extrinsic pro-apoptotic stimulus, a phenotype that was partially reversible upon UBR4 Arg/N-recognin silencing and consequent inhibition of procaspase-8 degradation. Collectively, our results shed light on how the interplay between NatB-mediated acetylation and the Arg/N-degron pathway appears to impact apoptosis regulation, providing new perspectives in the field including in therapeutic interventions.

[Research on bitter taste and efficacy of Ginkgo biloba extract based on UPLC-Q-TOF-MS~E integrated with molecular docking].

Based on high performance liquid chromatography-quadrupole time-of-flight tandem mass spectrometry(UPLC-Q-TOF-MS~E) and molecular docking technique, bitter compounds of Ginkgo biloba extract(GBE) were characterized, and their relationship with bitter efficacy was investigated. Firstly, UPLC-Q-TOF-MS~E was used for qualitative analysis of GBE components, and 60 chemical components were identified. These chemical components were molecular-docked with bitter receptors, and 26 bitter substances were selected, mainly flavonoids. Secondly, sensory and electronic tongue bitterness evaluation techniques were used to verify that total flavones of GBE were the main bitter substances, which was consistent with the molecular docking results. Finally, network pharmacology was used to predict and analyze bitter substances. The relationship between the target of bitter substance and bitter effect was explored. The key targets of bitter substances are CYP2B6, ALOX15, and PTGS2, etc., and bitter substances may exert a bitter efficacy by ac-ting on related disease targets, indicating that bitter substances of GBE are the material basis of the bitter effect. In summary, the study indicated that the molecular docking technique had a guiding effect on the screening of bitter substances in traditianal Chinese medicine(TCM), and bitter substances of GBE had a bitter efficacy. It provides ideas and references for the study of the "taste-efficacy relationship" of TCM in the future.

W/O/W Pickering emulsions stabilized by complex modified phycocyanin.

BACKGROUND: A water-in-oil-in-water (W/O/W) double emulsion can simultaneously load hydrophilic and hydrophobic substances due to its unique two-membrane, three-phase structure. However, thermodynamic instability greatly limits the application of double emulsions in food processing. Further development of Pickering emulsions based on proteins, etc., can improve the stability and loading capacity. It is of great significance to promote their practical application. RESULTS: Herein, we prepared ultrasound pretreatment complex glycation-modified phycocyanin (UMPC) to stabilize a W/O/W Pickering emulsion for the codelivery of vitamin B12 (VB12) and vitamin E (VE). First, an inner water phase and oil phase containing polyglycerin polyricinoleate were homogenized to prepare a W/O emulsion. Subsequently, the W/O emulsion was homogenized with an outer water phase containing UMPC to obtain a W/O/W Pickering emulsion. A gel-like inner phase emulsion with excellent storage and thermal stabilities was obtained under the condition that the W/O emulsion volume ratio was 80% and the UMPC was stabilized by 10 g kg-1. The double emulsion after loading VB12 and VE showed good encapsulation effect during the storage period, the encapsulation rate could reach more than 90%, it also showed excellent protection effect under long-time storage and UV irradiation and the retention rate increased by more than 65%. In addition, the bioavailability of VB12 and VE significantly increased during simulated gastrointestinal digestion and reached 46.02% and 52.43%, respectively. CONCLUSION: These results indicate that the UMPC-stabilized W/O/W Pickering emulsion is an effective carrier for the codelivery of hydrophilic and hydrophobic bioactive molecules and also provides a means for useful exploration of an efficient and stable emulsion system stabilized by biological macromolecules. © 2024 Society of Chemical Industry.

Oltipraz attenuated cerebral ischemia-reperfusion injury through inhibiting the oxidative stress and ferroptosis in mice.

Oltipraz (OPZ) is a synthetic dithiolethione and is considered a novel activator of nuclear factor E2-related factor 2 (Nrf2). Increasing evidence indicates that Nrf2 protects against cerebral ischemia/reperfusion (I/R) injury by antagonizing ferroptosis and lipid peroxidation. However, the protective effects of OPZ on cerebral I/R injury remain to be elucidated. We investigated the in vitro and in vivo neuroprotective effects of OPZ. Mice were subjected to middle cerebral artery occlusion/reperfusion (MCAO/R) to construct an in vivo model and PC12 cells were exposed to oxygen and glucose deprivation/reoxygenation (OGD/R) to establish an in vitro model. OPZ administration reduced the infarct volume and brain water content, and alleviated the neurological deficit of MCAO/R mice. Moreover, OPZ ameliorated MCAO/R-induced oxidative stress by decreasing the levels of 4-HNE and MDA and increasing the activities of SOD and GSH. We also found that OPZ ameliorated MCAO/R-induced ferroptosis by increasing SLC7A11 and GPX4 protein expression and downregulating ACSL4 protein expression. Similarly, the in vitro results revealed that OGD/R-induced oxidative stress and ferroptosis. Finally, mechanistic analysis revealed that OPZ significantly upregulated the Nrf2 expression and Nrf2 knockout (Nrf2 KO) abolished the OPZ-mediated protective effects. Taken together, these findings demonstrate that OPZ ameliorates cerebral I/R injury by suppressing the oxidative stress and ferroptosis.
