SARS-CoV-2 breakthrough infections enhance T cell response magnitude, breadth, and epitope repertoire.

Little is known about the effect of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2 or SARS2) vaccine breakthrough infections (BTIs) on the magnitude and breadth of the T cell repertoire after exposure to different variants. We studied samples from individuals who experienced symptomatic BTIs during Delta or Omicron waves. In the pre-BTI samples, 30% of the donors exhibited substantial immune memory against non-S (spike) SARS2 antigens, consistent with previous undiagnosed asymptomatic SARS2 infections. Following symptomatic BTI, we observed (1) enhanced S-specific CD4 and CD8 T cell responses in donors without previous asymptomatic infection, (2) expansion of CD4 and CD8 T cell responses to non-S targets (M, N, and nsps) independent of SARS2 variant, and (3) generation of novel epitopes recognizing variant-specific mutations. These variant-specific T cell responses accounted for 9%-15% of the total epitope repertoire. Overall, BTIs boost vaccine-induced immune responses by increasing the magnitude and by broadening the repertoire of T cell antigens and epitopes recognized.

Cytogenotoxicity evaluation of heavy metals detected in extracts and infusion of Baccharis trimera, potential bioaccumulator plant.

Heavy metals (HMs) are natural components of the Earth's crust that might originate from natural and anthropogenic sources. In excess quantities, the presence of these metals is harmful for both environment and human health. Taking this into account, various investigators examined bioaccumulator species in order to reduce environmental toxicity, among these Baccharis trimera. Therefore, the present study aimed to determine the capacity of B. trimera to bioaccumulate HMs and assess consequent cytogenotoxicity following exposure. B. trimera vegetative parts were collected from two groups (1) control, in which plants were cultivated in soil exposed to distilled water, and (2) exposed, in which plants were cultivated in soil exposed to HMs including manganese (Mn), iron (Fe), lead (Pb), copper (Cu), cobalt (Co), zinc (Zn), and chromium (Cr). HMs were quantified in cultivation soil and extracts (aqueous and ethanolic) as well as infusion of B. trimera vegetative parts. Root lengths and cytogenotoxic effects were determined using Allium cepa test. Results demonstrated that all HMs studied were absorbed and bioaccumulated by B. trimera. Root lengths were decreased when exposed to ethanolic extract of B. trimera cultivated in soil exposed to HMs solution, which was the extract that exhibited the highest cytogenotoxicity values. Thus, data demonstrated that B. trimera might serve as a bioaccumulator for the reduction of environmental toxicity associated with the presence of certain HMs.

Beliefs and concerns about pain were associated with craniofacial pain experienced within 24 hours: cross-sectional study / Crenças e preocupações sobre a dor têm associação à dor craniofacial experimentada nas últimas 24 horas: estudo transversal

ABSTRACT BACKGROUND AND OBJECTIVES: Although craniofacial pain has been associated with negative psychological aspects, how the patient's perception of their own illness could influence craniofacial pain is not elucidated yet. Therefore, this study aims to identify the main factors and beliefs about the illness that could influence pain intensity and pain duration in people who experienced craniofacial pain in the last 24 hours. METHODS: This cross-sectional study comprised undergraduate students, aged between 18 and 40 years old, who experienced self-reported craniofacial pain in the last 24 hours. Participants answered questions regarding body functions, activities and participation, and personal factors based on the International Classification of Functioning (ICF); In addition, questions from the Brief Illness Perceptual Questionnaire (Brief IPQ) were applied. The analysis was carried out with a single and multiple regression model. RESULTS: The sample comprised 87 volunteers. Pain intensity and duration experienced in the last 24 hours were associate by concerns about the presence of an illness and the need for treatment. Pain intensity was specifically associated with the importance of treatment and the extent to which the patient is concerned about their pain (R2=0.108). Pain duration was associated with how much the individual is worried about their illness (R2=0.1459). CONCLUSION: Both pain intensity and duration experienced in the last 24 hours are associated with concerns regarding the presence of an illness and beliefs related to such illness treatment, which reinforces the influence of psychosocial aspects on pain perception.

RESUMO JUSTIFICATIVA E OBJETIVOS: Embora a dor craniofacial seja associada a aspectos psicológicos negativos, ainda não está totalmente elucidado como a percepção do paciente sobre sua própria doença pode influenciá-la. Portanto, este estudo teve como objetivo identificar os principais fatores e as crenças sobre a doença que podem influenciar a intensidade e a duração da dor em pessoas que sentiram dor craniofacial nas últimas 24 horas. MÉTODOS: Estudo transversal composto por universitários, com idade entre 18 e 40 anos, que relataram dor craniofacial nas últimas 24 horas. Os voluntários responderam a perguntas sobre funções corporais, atividades e participação e fatores pessoais com base na classificação da Classificação Internacional de Funcionalidades (CIF). Além disso, foram aplicadas questões do Questionário de Percepção de Doenças Versão Breve (Brief IPQ). A análise foi realizada com um modelo de regressão simples e múltiplo. RESULTADOS: A amostra foi composta por 87 voluntários. A intensidade e a duração da dor sentida nas últimas 24 horas foram influenciadas pela preocupação com a presença de doença e com a necessidade de tratamento. A intensidade da dor foi associada à importância do tratamento e à preocupação do paciente com sua dor (R2=0,108). A duração da dor associou-se à preocupação do indivíduo com sua doença (R2=0,1459). CONCLUSÃO: Tanto a intensidade quanto a duração da dor vivenciadas nas últimas 24 horas são influenciadas pela preocupação com a presença de doença e crenças relacionadas ao seu tratamento, o que reforça a influência dos aspectos psicossociais na percepção da dor.

Prior SARS-CoV-2 Infection Enhances Initial mRNA Vaccine Response with a Lower Impact on Long-Term Immunity.

Spike-encoding mRNA vaccines in early 2021 effectively reduced SARS-CoV-2-associated morbidity and mortality. New booster regimens were introduced due to successive waves of distinct viral variants. Therefore, people now have a diverse immune memory resulting from multiple SARS-CoV-2 Ag exposures, from infection to following vaccination. This level of community-wide immunity can induce immunological protection from SARS-CoV-2; however, questions about the trajectory of the adaptive immune responses and long-term immunity with respect to priming and repeated Ag exposure remain poorly explored. In this study, we examined the trajectory of adaptive immune responses following three doses of monovalent Pfizer BNT162b2 mRNA vaccination in immunologically naive and SARS-CoV-2 preimmune individuals without the occurrence of breakthrough infection. The IgG, B cell, and T cell Spike-specific responses were assessed in human blood samples collected at six time points between a moment before vaccination and up to 6 mo after the third immunization. Overall, the impact of repeated Spike exposures had a lower improvement on T cell frequency and longevity compared with IgG responses. Natural infection shaped the responses following the initial vaccination by significantly increasing neutralizing Abs and specific CD4+ T cell subsets (circulating T follicular helper, effector memory, and Th1-producing cells), but it had a small benefit at long-term immunity. At the end of the three-dose vaccination regimen, both SARS-CoV-2-naive and preimmune individuals had similar immune memory quality and quantity. This study provides insights into the durability of mRNA vaccine-induced immunological memory and the effects of preimmunity on long-term responses.

Banda ortodôntica como alternativa de tratamento conservador provisório para primeiros molares permanentes com hipomineralização molar incisivo (HMI): relato de caso / Orthodontic banding as an alternative provisional conservative treatment for permanent first molars with incisor molar hypomineralization (IMH): case report

Introdução: a Hipomineralização Molar Incisivo (HMI) é um defeito qualitativo de desenvolvimento de esmalte que pode ocasionar fraturas pós-eruptivas (FPE), lesões de cárie e sensibilidade. Objetivo: relatar o tratamento de HMI severa através da cimentação de bandas ortodônticas para preservação da estrutura dentária em primeiros molares permanentes inferiores com FPE. Relato do caso: criança do sexo feminino, 10 anos de idade, apresentou-se com queixa de hipersensibilidade e fratura dentária associada à restauração prévia. Clinicamente, observou-se presença de HMI severa, com FPE associada à lesão de cárie em dentina nas superfícies oclusal e vestibular do dente 36 e restauração insatisfatória com cimento de ionômero de vidro (CIV) na superfície vestibular do dente 46 que apresentava opacidades demarcadas branco-creme. Radiograficamente, observou-se ausência de comprometimento pulpar. Após manejo por meio de abordagens não-invasivas (controle de biofilme e dieta e aplicação de verniz fluoretado), o tratamento proposto foi a cimentação de banda ortodôntica com CIV modificado por resina (Riva Light Cure®, SDI) nos dentes 36 e 46 para maior longevidade das restaurações. O tratamento restaurador atraumático (TRA) foi realizado no dente 36 previamente à cimentação da banda ortodôntica. Resultados: após o tratamento, a criança não relatou dor ou desconforto e as restaurações mantiveram-se intactas. A mãe da criança foi orientada quanto à importância de acompanhamento periódico a cada 4 meses. Conclusão: a cimentação das bandas ortodônticas com CIV possibilitou o manejo conservador de molares permanentes com HMI severa, com manutenção de sua funcionalidade oclusal, saúde pulpar e gengival, proporcionando melhor qualidade de vida à paciente.

Introduction: molar Incisor Hypomineralization (MIH) is a qualitative developmental enamel defect that can cause posteruptive enamel breakdown (PEB), caries lesions, and sensitivity. Objective: to report the treatment of a child with severe MIH through the cementation of orthodontic bands in lower first permanent molars with PEB to preserve tooth structure. Case report: female child, 10 years old, presenting hypersensitivity complaints and tooth fracture associated with previous restoration. Severe MIH was observed, with PEB associated with dentin caries on the occlusal and buccal surfaces of tooth #36 and unsatisfactory glass ionomer cement (GIC) restoration on the buccal surface of tooth #46 which had creamy-white marked opacities. There was no pulp involvement radiographically. After management through non-invasive approaches (biofilm and diet control and application of fluoride varnish), the proposed treatment was the cementation of an orthodontic band with resin-modified GIC (Riva Light Cure®, SDI) on teeth #36 and #46 to long-term lifespan restorations. Atraumatic restorative treatment (ART) was performed on tooth #36 prior to the cementation of the orthodontic band. Results: after treatment, the child did not report pain or discomfort and the restorations remained intact. The child's mother was instructed about the importance of periodic follow-up visits every 4 months. Conclusion: the cementation of orthodontic bands with GIC allowed the conservative management of permanent molars with severe MIH, maintaining their functional occlusion, pulpal and gingival health, providing a better quality of life to the patient.

Heavy metal accumulation efficiency and subsequent of cytogenotoxicity evaluation in the medicinal plant Equisetum hyemale.

Heavy metals in soils represent a threat to the environment, food safety, as well as human and animal health. The bioaccumulation of these elements in plants might enhance medium- and long-term adverse health risk promoting genetic alterations that lead to dermal, gastrointestinal, circulatory, renal, and brain disorders. The present study aimed to determine the bioaccumulation potential and cytogenotoxic effect of Equisetum hyemale extracts. E. hyemale seedlings were divided into two groups: exposed group (plants cultivated in soil with heavy metals solution) and control (plants cultivated in soil with distilled water). Heavy metals were quantified in the cultivation soils (control and exposed) and extracts (ethanolic and infusion) of vegetative parts from E. hyemale cultivated in both soils. Root length and cytogenotoxic effect were determined utilizing Allium cepa bioassay. Data demonstrated that Equisetum hyemale present the ability to absorb and bioaccumulate different heavy metals including lead, copper, cobalt manganese, zinc, iron and chromium. Given this property E. hyemale may be considered a reliable bioindicator to assess cytogenotoxicity of certain substances that exert adverse risks to environment and human and animal health.

The Effect of Waning on Antibody Levels and Memory B Cell Recall following SARS-CoV-2 Infection or Vaccination.

In order to longitudinally track SARS-CoV-2 antibody levels after vaccination or infection, we assessed anti-RBD antibody levels in over 1000 people and found no significant decrease in antibody levels during the first 14 months after infection in unvaccinated participants, however, a significant waning of antibody levels was observed following vaccination. Participants who were pre-immune to SARS-CoV-2 prior to vaccination seroconverted to higher antibody levels, which were maintained at higher levels than in previously infected, unvaccinated participants. Older participants exhibited lower level of antibodies after vaccination, but a higher level after infection than younger people. The rate of antibody waning was not affected by pre-immunity or age. Participants who received a third dose of an mRNA vaccine not only increased their antibody levels ~14-fold, but also had ~3 times more antibodies compared to when they received their primary vaccine series. PBMC-derived memory B cells from 13 participants who lost all circulating antibodies were differentiated into antibody secreting cells (ASCs). There was a significant recall of memory B cell ASCs in the absence of serum antibodies in 5-8 of the 10 vaccinated participants, but not in any of the 3 infected participants, suggesting a strong connection between antibody levels and the effectiveness of memory B cell recall.

The effect of waning on antibody levels and memory B cell recall following SARS-CoV-2 infection or vaccination.

As of March 2022, there have been over 450 million reported SARS-CoV-2 cases worldwide, and more than 4 billion people have received their primary series of a COVID-19 vaccine. In order to longitudinally track SARS-CoV-2 antibody levels in people after vaccination or infection, a large-scale COVID-19 sero-surveillance progam entitled SPARTA (SeroPrevalence and Respiratory Tract Assessment) was established early in the pandemic. Anti-RBD antibody levels were tracked in more than 1,000 people. There was no significant decrease in antibody levels during the first 14 months after infection in unvaccinated participants, however, significant waning of antibody levels was observed following vaccination, regardless of previous infection status. Moreover, participants who were pre-immune to SARS-CoV-2 prior to vaccination seroconverted to significantly higher antibody levels, and antibodies were maintained at significantly higher levels than in previously infected, unvaccinated participants. This pattern was entirely due to differences in the magnitude of the initial seroconversion event, and the rate of antibody waning was not significantly different based on the pre-immune status. Participants who received a third (booster) dose of an mRNA vaccine not only increased their anti-RBD antibody levels ∼14-fold, but they also had ∼3 times more anti-RBD antibodies compared to the peak of their antibody levels after receiving their primary vaccine series. In order to ascertain whether the presence of serum antibodies is important for long-term seroprotection, PBMCs from 13 participants who lost all detectable circulating antibodies after vaccination or infection were differentiated into memory cells in vitro . There was a significant recall of memory B cells in the absence of serum antibodies in 70% of the vaccinated participants, but not in any of the infected participants. Therefore, there is a strong connection between anti-RBD antibody levels and the effectiveness of memory B cell recall.

Medicinal plant use in primary health care: an integrative review. / O uso de plantas medicinais na atenção primária à saúde: revisão integrativa.

Medicinal plant (MP) use supports comprehensiveness of care in Primary Health Care (PHC), enabling appreciation of popular knowledge and self-care. This integrative literature review aims to analyze researches that approach the insertion of using MP in PHC. PICO strategy was used as a guideline in search of evidence, reuniting 18 articles published between January 2015 and August 2020, in the Virtual Health Library and PubMed databases. The variables of analysis were knowledge of PHC healthcare professionals about MP and associated policies, MP use by its users, highlighting their profile, the reasons that lead to the use and lack of security in MP use. The results show insufficient knowledge of healthcare professionals about Integrative and Complementary Practices policies and the medicinal uses of plants. The main users are women, elderly, with low income and education, either in Brazil or other countries. Regarding safety in MP use, frequently there is no correct identification of species, its origin, its preparation and the appropriate dose for each case. Finally, failure to approach these contents during training of healthcare professionals generates less knowledge, less research and more prejudice due to lack of information, impairing incentive and dissemination to the community.

O uso de plantas medicinais (PM) favorece a integralidade do cuidado na atenção primária à saúde (APS), valorizando o saber popular e o autocuidado. Esta revisão integrativa de literatura objetiva analisar estudos sobre a inserção do uso de PM na APS. A estratégia PICO norteou a busca de evidências, reunindo 18 artigos publicados de janeiro de 2015 a agosto de 2020 nos bancos de dados Biblioteca Virtual de Saúde e PubMed. As variáveis de análise foram o conhecimento dos profissionais da saúde da APS sobre PM e políticas associadas, o uso de PM pelos usuários, destacando seu perfil, fatores que favorecem o uso e a falta de segurança no uso de PM. A literatura aponta insuficiência de conhecimento dos profissionais de saúde sobre as políticas de práticas integrativas e complementares e o uso de plantas para fins medicinais. Os principais usuários são mulheres, idosas, com baixa renda e escolaridade, tanto no Brasil quanto em outros países. Sobre a segurança no uso de PM, frequentemente não há correta identificação de espécie, origem, preparo e dose adequada para cada caso. Por fim, a não abordagem desses conteúdos durante a formação de profissionais da saúde gera menos conhecimento, menos pesquisas e mais preconceito por falta de informação, prejudicando o incentivo e divulgação à comunidade.

Refractory feline sporotrichosis: a comparative analysis on the clinical, histopathological, and cytopathological aspects / Esporotricose felina refratária: uma análise comparativa sobre os aspectos clínico, histopatológico e citopatológico

Sporotrichosis is a chronic fungal infection caused by Sporothrix species. The occurrence of cases that are resistant to long-term treatment, especially in the nasal planum of cats, emphasizes the importance of studying its pathogenesis. The purpose of this study was to analyze and compare the inflammatory process of cutaneous lesions of feline refractory sporotrichosis to clinical aspects through cytopathological and histopathological examination. Moreover, the study included 13 cats with cutaneous lesions that had been resistant to itraconazole treatment for more than a year. Cutaneous lesions samples were collected for cytopathological, histopathological, and fungal culture analyses. Tissue fragments were processed and stained with hematoxylin-eosin (HE) and Grocott methenamine silver (GMS). Further, two clinical presentations had the highest occurrence: the localized cutaneous form in animals with good general condition and stable disease (n=9, 69.2%) and the disseminated cutaneous form in cats with poor general condition (n=4, 30.8%). In cats with refractory sporotrichosis, the nasal planum (84.6%) was the most common location of lesions. In the cytopathological study, cats with fewer than two lesions and in good general condition (n=9, 69.2%) showed absence or mild yeast intensity (up to 5 yeasts per field), lower intensity of macrophages and neutrophils, and higher intensity of epithelioid cells, lymphocytes, plasma cells, and eosinophils. On the other hand, (n=4, 30.8%) of the cats with disseminated sporotrichosis and a poor general condition had a marked intensity of yeasts, which were mostly phagocytosed by an increased number of macrophages and neutrophils. Of those animals with good general condition, the majority (n=6, 66.7%) had higher eosinophil intensity. In histopathology, malformed suppurative granuloma was the predominant type (n=9, 69.2%) in feline sporotrichosis lesions, followed by well-formed granulomas (n=4, 30.8%). Malformed granulomas showed mild to moderate fungal intensity (55.6%) in animals with good general condition and localized lesions while marked fungal intensity (44.4%) in cats with the disseminated form of the disease and poor general condition. Well-formed granulomas (n=4, 30.7%) had mild to moderate intensity of fungal load, and 75% of the animals with this type of granuloma had only one lesion and were in good general condition. Long-term itraconazole treatment in these cats with refractory sporotrichosis can keep the infection under control and localized lesions stable; however, fungus reactivation can occur, resulting in an exuberant and inefficient immune response.

A esporotricose é uma infecção fúngica crônica causada por espécies do gênero Sporothrix. A ocorrência de casos refratários ao tratamento de longo prazo, especialmente na região nasal de gatos, alerta para a importância do estudo de sua patogênese. Este estudo teve como objetivo analisar o processo inflamatório das lesões cutâneas de esporotricose felina refratária ao tratamento, por meio de exames citopatológico e histopalógico, e comparar com aspectos clínicos. Treze gatos com lesões cutâneas refratárias ao tratamento com Itraconazol por mais de um ano foram incluídos no estudo. Amostras de lesões cutâneas foram coletadas para análises citopatológicas, histopatológicas e cultura fúngica. Fragmentos de tecidos foram processados e corados pela hematoxilina-eosina (HE) e Prata Metenamina de Grocott (GMS). Duas apresentações clínicas tiveram maior ocorrência: a forma localizada cutânea em animais com bom estado geral e doença estável (n=9, 69,2%); e a forma disseminada cutânea em gatos com estado geral ruim (n=4, 30,8%). A região nasal (84,6%) foi a localização mais frequente das lesões nos gatos com esporotricose refratária ao tratamento. No estudo citopatológico, felinos com menos de duas lesões, e em bom estado geral, (n=9, 69,2%) revelaram ausência ou leve intensidade de leveduras (até 5 leveduras por campo), menor intensidade de macrófagos e neutrófilos, e maior intensidade de células epitelióides, linfócitos, plasmócitos e eosinófilos. Enquanto, (n=4, 30,8%) dos felinos que apresentavam a forma disseminada da esporotricose associada a um estado geral ruim, revelaram acentuada intensidade de leveduras em sua maioria fagocitadas por acentuado número de macrófagos e neutrófilos. Dos animais com bom estado geral, a maioria (n=6, 66,7%) apresentava maior intensidade de eosinófilos. Na histopatologia, o granuloma supurativo mal formado foi o tipo predominante (n=9, 69,2%) nas lesões de esporotricose felina, e (n=4, 30,8%) foram de granulomas bem formados. Granulomas mal formados apresentaram leve a moderada intensidade fúngica (55,6%) nos animais com bom estado geral e lesões localizadas, e acentuada intensidade fúngica (44,4%) nos gatos com a forma disseminada da doença e estado geral ruim. Granulomas bem formados (n=4, 30,7%) apresentaram leve a moderada intensidade de carga fúngica, sendo 75% dos animais com esse tipo de granuloma com apenas uma lesão e bom estadogeral. O tratamento de longo prazo com itraconazol, nesses gatos com esporotricose refratária, pode manter a infecção controlada e lesões localizadas estáveis de forma temporária, contudo a reativação do fungo pode ocorrer levando a uma resposta imunológica exuberante e ineficiente.

Cutaneous lesions samples were collected for cytopathological, histopathological, and fungal culture analyses. Tissue fragments were processed and stained with hematoxylin-eosin (HE) and Grocott methenamine silver (GMS). Further, two clinical presentations had the highest occurrence: the localized cutaneous form in animals with good general condition and stable disease (n=9, 69.2%) and the disseminated cutaneous form in cats with poor general condition (n=4, 30.8%). In cats with refractory sporotrichosis, the nasal planum (84.6%) was the most common location of lesions. In the cytopathological study, cats with fewer than two lesions and in good general condition (n=9, 69.2%) showed absence or mild yeast intensity (up to 5 yeasts per field), lower intensity of macrophages and neutrophils, and higher intensity of epithelioid cells, lymphocytes, plasma cells, and eosinophils. On the other hand, (n=4, 30.8%) of the cats with disseminated sporotrichosis and a poor general condition had a marked intensity of yeasts, which were mostly phagocytosed by an increased number of macrophages and neutrophils. Of those animals with good general condition, the majority (n=6, 66.7%) had higher eosinophil intensity. In histopathology, malformed suppurative granuloma was the predominant type (n=9, 69.2%) in feline sporotrichosis lesions, followed by well-formed granulomas (n=4, 30.8%). Malformed granulomas showed mild to moderate fungal intensity (55.6%) in animals with good general condition and localized lesions while marked fungal intensity (44.4%) in cats with the disseminated form of the disease and poor general condition. Well-formed granulomas (n=4, 30.7%) had mild to moderate intensity of fungal load, and 75% of the animals with this type of granuloma had only one lesion and were in good general condition. Long-term itraconazole treatment in these cats with refractory sporotrichosis can keep the infection under control and localized lesions stable; however, fungus reactivation can occur, resulting in an exuberant and inefficient immune response.(AU)

A esporotricose é uma infecção fúngica crônica causada por espécies do gênero Sporothrix. A ocorrência de casos refratários ao tratamento de longo prazo, especialmente na região nasal de gatos, alerta para a importância do estudo de sua patogênese. Este estudo teve como objetivo analisar o processo inflamatório das lesões cutâneas de esporotricose felina refratária ao tratamento, por meio de exames citopatológico e histopalógico, e comparar com aspectos clínicos. Treze gatos com lesões cutâneas refratárias ao tratamento com Itraconazol por mais de um ano foram incluídos no estudo. Amostras de lesões cutâneas foram coletadas para análises citopatológicas, histopatológicas e cultura fúngica. Fragmentos de tecidos foram processados e corados pela hematoxilina-eosina (HE) e Prata Metenamina de Grocott (GMS). Duas apresentações clínicas tiveram maior ocorrência: a forma localizada cutânea em animais com bom estado geral e doença estável (n=9, 69,2%); e a forma disseminada cutânea em gatos com estado geral ruim (n=4, 30,8%). A região nasal (84,6%) foi a localização mais frequente das lesões nos gatos com esporotricose refratária ao tratamento. No estudo citopatológico, felinos com menos de duas lesões, e em bom estado geral, (n=9, 69,2%) revelaram ausência ou leve intensidade de leveduras (até 5 leveduras por campo), menor intensidade de macrófagos e neutrófilos, e maior intensidade de células epitelióides, linfócitos, plasmócitos e eosinófilos. Enquanto, (n=4, 30,8%) dos felinos que apresentavam a forma disseminada da esporotricose associada a um estado geral ruim, revelaram acentuada intensidade de leveduras em sua maioria fagocitadas por acentuado número de macrófagos e neutrófilos. Dos animais com bom estado geral, a maioria (n=6, 66,7%) apresentava maior intensidade de eosinófilos. Na histopatologia, o granuloma supurativo mal formado foi o tipo predominante (n=9, 69,2%) nas lesões de esporotricose felina, e (n=4, 30,8%) foram de granulomas bem formados. Granulomas mal formados apresentaram leve a moderada intensidade fúngica (55,6%) nos animais com bom estado geral e lesões localizadas, e acentuada intensidade fúngica (44,4%) nos gatos com a forma disseminada da doença e estado geral ruim. Granulomas bem formados (n=4, 30,7%) apresentaram leve a moderada intensidade de carga fúngica, sendo 75% dos animais com esse tipo de granuloma com apenas uma lesão e bom estadogeral. O tratamento de longo prazo com itraconazol, nesses gatos com esporotricose refratária, pode manter a infecção controlada e lesões localizadas estáveis de forma temporária, contudo a reativação do fungo pode ocorrer levando a uma resposta imunológica exuberante e ineficiente.(AU)

O uso de plantas medicinais na atenção primária à saúde: revisão integrativa / Medicinal plant use in primary health care: an integrative review

Resumo O uso de plantas medicinais (PM) favorece a integralidade do cuidado na atenção primária à saúde (APS), valorizando o saber popular e o autocuidado. Esta revisão integrativa de literatura objetiva analisar estudos sobre a inserção do uso de PM na APS. A estratégia PICO norteou a busca de evidências, reunindo 18 artigos publicados de janeiro de 2015 a agosto de 2020 nos bancos de dados Biblioteca Virtual de Saúde e PubMed. As variáveis de análise foram o conhecimento dos profissionais da saúde da APS sobre PM e políticas associadas, o uso de PM pelos usuários, destacando seu perfil, fatores que favorecem o uso e a falta de segurança no uso de PM. A literatura aponta insuficiência de conhecimento dos profissionais de saúde sobre as políticas de práticas integrativas e complementares e o uso de plantas para fins medicinais. Os principais usuários são mulheres, idosas, com baixa renda e escolaridade, tanto no Brasil quanto em outros países. Sobre a segurança no uso de PM, frequentemente não há correta identificação de espécie, origem, preparo e dose adequada para cada caso. Por fim, a não abordagem desses conteúdos durante a formação de profissionais da saúde gera menos conhecimento, menos pesquisas e mais preconceito por falta de informação, prejudicando o incentivo e divulgação à comunidade.

Abstract Medicinal plant (MP) use supports comprehensiveness of care in Primary Health Care (PHC), enabling appreciation of popular knowledge and self-care. This integrative literature review aims to analyze researches that approach the insertion of using MP in PHC. PICO strategy was used as a guideline in search of evidence, reuniting 18 articles published between January 2015 and August 2020, in the Virtual Health Library and PubMed databases. The variables of analysis were knowledge of PHC healthcare professionals about MP and associated policies, MP use by its users, highlighting their profile, the reasons that lead to the use and lack of security in MP use. The results show insufficient knowledge of healthcare professionals about Integrative and Complementary Practices policies and the medicinal uses of plants. The main users are women, elderly, with low income and education, either in Brazil or other countries. Regarding safety in MP use, frequently there is no correct identification of species, its origin, its preparation and the appropriate dose for each case. Finally, failure to approach these contents during training of healthcare professionals generates less knowledge, less research and more prejudice due to lack of information, impairing incentive and dissemination to the community.

Associação entre o consumo alimentar e o estado nutricional de crianças pré-escolares do município de Venâncio Aires ­ RS, Brasil

Introdução: Devido às alterações no padrão nutricional da população, o excesso de peso já acomete uma em cada três crianças pré-escolares no Brasil. Objetivo: Avaliar a associação entre o estado nutricional e o consumo alimentar dos pré-escolares das escolas municipais e particulares do município de Venâncio Aires, Vale do Rio Pardo, Rio Grande do Sul, Brasil. Métodos: Estudo de corte transversal, descritivo e quantitativo da avaliação antropométrica de peso e altura, bem como, do consumo alimentar utilizando o formulário de marcadores de consumo alimentar do sistema de vigilância alimentar e nutricional de 508 crianças, dois a seis anos incompletos; aplicado entre novembro e dezembro de 2018. Resultados: A maioria das crianças apresentou Eutrofia (67,9%; n = 345), seguida de risco de sobrepeso (16,3%; n = 83), conforme o Índice de Massa Corporal para a Idade (IMC/I) e elevado consumo de alimentos ultra processados, tais como, bebidas adoçadas (59,8%; n = 304), macarrão instantâneo, salgadinhos de pacote ou biscoitos salgados (47,2%; n = 240) e biscoitos recheados, doces ou guloseimas (57,7%; n = 293). Nestas crianças, constatou-se que não tomar café da manhã foi associado de forma significativa ao hábito de fazer refeições em frente à televisão, computadores e celulares (p = 0,014). O consumo de hambúrguer e/ou embutidos (p < 0,001), macarrão instantâneo, salgadinhos de pacote e biscoitos salgados (p = 0,036), bem como, de biscoito recheado, doces ou guloseimas (p = 0,030) apresentou associação significativa ao ato de realizar as refeições em frente à televisão, computadores e celulares. Entretanto, o estado nutricional das crianças não foi associado de forma significativa ao consumo de alimentos ultraprocessados (p ≥ 0,05). Conclusão: No município de Venâncio Aires, não houve associação significativa entre o consumo de alimentos ultra processados e o estado nutricional entre as crianças pré-escolares. Entretanto, o consumo de alimentos industrializados, como hambúrguer e/ou embutidos, macarrão instantâneo, salgadinhos de pacote e biscoitos salgados e recheados, bem como, doces ou guloseimas, foi associado significativamente ao hábito de ingerir refeições em frente à televisão, computadores e celulares.

A Comparison of Two Structurally Related Human Milk Oligosaccharide Conjugates in a Model of Diet-Induced Obesity.

Obesity is the largest risk factor for the development of chronic diseases in industrialized countries. Excessive fat accumulation triggers a state of chronic low-grade inflammation to the detriment of numerous organs. To address this problem, our lab has been examining the anti-inflammatory mechanisms of two human milk oligosaccharides (HMOs), lacto-N-fucopentaose III (LNFPIII) and lacto-N-neotetraose (LNnT). LNFPIII and LNnT are HMOs that differ in structure via presence/absence of an α1,3-linked fucose. We utilize LNFPIII and LNnT in conjugate form, where 10-12 molecules of LNFPIII or LNnT are conjugated to a 40 kDa dextran carrier (P3DEX/NTDEX). Previous studies from our lab have shown that LNFPIII conjugates are anti-inflammatory, act on multiple cell types, and are therapeutic in a wide range of murine inflammatory disease models. The α1,3-linked fucose residue on LNFPIII makes it difficult and more expensive to synthesize. Therefore, we asked if LNnT conjugates induced similar therapeutic effects to LNFPIII. Herein, we compare the therapeutic effects of P3DEX and NTDEX in a model of diet-induced obesity (DIO). Male C57BL/6 mice were placed on a high-fat diet for six weeks and then injected twice per week for eight weeks with 25µg of 40 kDa dextran (DEX; vehicle control), P3DEX, or NTDEX. We found that treatment with P3DEX, but not NTDEX, led to reductions in body weight, adipose tissue (AT) weights, and fasting blood glucose levels. Mice treated with P3DEX also demonstrated improvements in glucose homeostasis and insulin tolerance. Treatment with P3DEX or NTDEX also induced different profiles of serum chemokines, cytokines, adipokines, and incretin hormones, with P3DEX notably reducing circulating levels of leptin and resistin. P3DEX also reduced WAT inflammation and hepatic lipid accumulation, whereas NTDEX seemed to worsen these parameters. These results suggest that the small structural difference between P3DEX and NTDEX has significant effects on the conjugates' therapeutic abilities. Future work will focus on identifying the receptors for these conjugates and delineating the mechanisms by which P3DEX and NTDEX exert their effects.

Esporotricose felina: um relato de caso de disseminação cutânea e sistêmica em gato negativo para FIV e FeLV / Feline sporotrichosis: a case report of cutaneous and systemic dissemination in cat negative for FIV and FeLV

A esporotricose é uma zoonose causada por fungos do gênero Sporothrix. Os gatos doentes têm importante potencial zoonótico e frequentemente revelam uma apresentação disseminada da doença. O objetivo deste relato de caso é descrever as características clínicas e anatomopatológicas de um caso de esporotricose felina refratária ao tratamento com apresentação clínica cutânea disseminada e sistêmica. Um felino macho de 3 anos de idade foi tratado para esporotricose com itraconazol e obteve resolução completa das lesões cutâneas. Porém, um ano após alta clínica, o animal apresentou aumento e ulceração da região nasal. Após cultura fúngica positiva para Sporothrix spp foi instituído tratamento com itraconazol 100mg associado ao iodeto de potássio 20mg por via oral diariamente e transcorrido 3 meses de tratamento, foi observada piora progressiva do sinais clínicos com disseminação de lesões para outras regiões do corpo. O animal foi submetido à eutanásia e encaminhado para necrópsia no Serviço de Anatomia Patológica da Faculdade de Veterinária da Universidade Federal Fluminense. Amostras da língua, pulmão, fígado, baço, rim, cérebro, linfonodo e pele foram coletadas para evidência de disseminação do agente fúngico e avaliação de alterações microscópicas. A coloração de metenamina de prata de Grocott foi utilizada para facilitar a visualização de leveduras sugestivas de Sporothrix spp

Sporotrichosis is a zoonosis caused by fungi of the genus Sporothrix. Sick cats have an significant zoonotic potential and often show a widespread presentation of the disease. The purpose of this case report is to describe the clinical and anatomopathological characteristics of a case of feline sporotrichosis refractory to treatment with disseminated and systemic cutaneous clinical presentation. A 3-year-old male feline was treated for sporotrichosis with itraconazole and achieved complete resolution of the skin lesions. However, one year after clinical discharge, the animal presented an increase and ulceration of the nasal region. After a positive fungal culture for Sporothrix spp, treatment with itraconazole 100mg associated with potassium iodide 20mg was instituted orally daily and after 3 months of treatment, a progressive worsening of the symptoms was observed with the spread of lesions to other regions of the body. The animal was euthanized and sent for necropsy at the Pathological Anatomy Service of the Veterinary Faculty of Universidade Federal Fluminense. Samples of the tongue, lung, liver, spleen, kidney, brain, lymph node, and skin were collected for evidence of spread of the fungal agent and evaluation of microscopic changes. Grocott silver methenamine staining was used to facilitate the visualization of yeasts suggestive of Sporothrix spp in histological sections. Yeasts were visualized in samples of skin, tongue, lymph node, kidney, liver, spleen, and brain. In the present report, the spread of Sporothrix spp to different organs signals the need for a thorough investigation of severe cases of feline sporotrichosis for the proper treatment.
