Arsenic, Cadmium, and Lead Levels in School Meals and Their Risk Assessment in Municipalities in Bahia, Brazil.

BACKGROUND: School meals represent a significant supply of nutrients for children in Brazil, especially those in conditions of social vulnerability. OBJECTIVES: This study aimed to assess the levels of arsenic (As), cadmium (Cd), and lead (Pb) in meals served in public elementary schools in four municipalities in the state of Bahia, Brazil, and assess the risk posed to children's health. METHODS: Ninety-six samples were collected from 16 schools, freeze-dried, and subjected to microwave-assisted digestion. The As, Cd, and Pb levels were determined by graphite furnace atomic absorption spectrometry. The risk assessment was based on calculating each element's hazard quotient (HQ). RESULTS: None of the samples reached or exceeded the tolerable levels for the elements analyzed. Pb was the metal that obtained the most significant result, reaching maximum levels of 39-157 µg·kg-1. CONCLUSIONS: No element exceeded the PTWI proposed by JECFA; thus, the toxic metal content in school meals poses a negligible risk to children's health.

Role of TRPA1 in the pharmacological effect triggered by the topical application of trans-anethole in mice.

PURPOSE: This study investigated the pharmacological effects of topical trans-anethole, a natural compound found in anise, star anise, and fennel essential oils, and its relationship with the transient receptor potential of ankyrin 1 (TRPA1). METHODS: The effects of topical anethole were assessed by eye wiping, nociceptive behaviour, and ear oedema in mice. Histological evaluations were performed on the ears of the animals topically treated with anethole. RESULTS: Anethole caused less eye irritation than capsaicin (a TRPV1 agonist) and allyl isothiocyanate (a TRPA1 agonist). Anethole (250 and 500 nmol/20 µL/paw) promoted neurogenic nociception in the paw (20.89 ± 3.53 s and 47.56 ± 8.46 s, respectively) compared with the vehicle (0.88 ± 0.38 s). HC030031 (56.1 nmol/20 µL/paw), a TRPA1 antagonist, abolished this nociceptive response. Anethole (4, 10, and 20 µmol/20 µL/ear) induced ear oedema (30.25 ± 4.78 µm, 78.00 ± 3.74 µm, and 127.50 ± 27.19 µm, respectively) compared with the vehicle (5.00 ± 0.5 µm). HC030031 (56.1 nmol/20 µL/ear) inhibited the oedema induced by anethole (10 µmol/20 µL/ear). Ears pre-treated with anethole or allyl isothiocyanate on the first day and re-exposed to these compounds on the third day showed a reduction in oedema (68.16 ± 6.04% and 38.81 ± 8.98.9%, respectively). Cross-desensitisation between anethole and allyl isothiocyanate was observed. Histological analysis confirmed the beneficial effects of anethol. CONCLUSION: As repeated topical applications of anethole induce the desensitisation of TRPA1, we suggest its clinical application as a topical formulation for treating skin diseases or managing pain associated with this receptor. Anethole may also have advantages over capsaicin and allyl isothiocyanate because of its low pungency and pleasant aroma.

Antisense Oligonucleotide as a New Technology Application for CsLOB1 Gene Silencing Aiming at Citrus Canker Resistance.

Citrus canker disease, caused by Xanthomonas citri subsp. citri, poses a significant threat to global citrus production. The control of the disease in the field relies mainly on the use of conventional tools such as copper compounds, which are harmful to the environment and could lead to bacterial resistance. This scenario stresses the need for new and sustainable technologies to control phytopathogens, representing a key challenge in developing studies that translate basic into applied knowledge. During infection, X. citri subsp. citri secretes a transcriptional activator-like effector that enters the nucleus of plant cells, activating the expression of the canker susceptibility gene LATERAL ORGAN BOUNDARIES 1 (LOB1). In this study, we explored the use of antisense oligonucleotides (ASOs) with phosphorothioate modifications to transiently inhibit the gene expression of CsLOB1 in Citrus sinensis. We designed and validated three potential ASO sequences, which led to a significant reduction in disease symptoms compared with the control. The selected ASO3-CsLOB1 significantly decreased the expression level of CsLOB1 when delivered through two distinct delivery methods, and the reduction of the symptoms ranged from approximately 15 to 83%. Notably, plants treated with ASO3 did not exhibit an increase in symptom development over the evaluation period. This study highlights the efficacy of ASO technology, based on short oligonucleotide chemically modified sequences, as a promising tool for controlling phytopathogens without the need for genetic transformation or plant regeneration. Our results demonstrate the potential of ASOs as a biotechnological tool for the management of citrus canker disease.

The knowledge of primary health care professionals regarding mental health: diagnosis by mhGAP.

OBJECTIVE: To analyze knowledge about priority topics in mental health care of strategic actors who work in regions where the Health Care Planning (PAS) methodology is used. METHODS: This is a quantitative, descriptive, cross-sectional, and observational study carried out with professionals from six health regions, distributed in three Brazilian states (Goiás, Rondônia and Maranhão) and linked to the project "Saúde mental na APS" (Mental health in PHC) of the Programa de Apoio ao Desenvolvimento Institucional do Sistema Único de Saúde (Proadi-SUS - Institutional Development Support Program of the Brazilian Unified Health System). The sample was made up of professionals who participated in the intervention guide multiplier training stage for mental, neurological and alcohol and other drug use disorders in the primary health care network, from July to September 2022. Data collection was through a self-administered instrument, in electronic format, consisting of a block with socioeconomic items and a structured questionnaire to assess participants' knowledge about priority topics in mental health. Descriptive analyses and comparison of proportions were conducted to analyze the data. RESULTS: A total of 354 health professionals participated in the study. Regarding the percentage of correct answers in the questionnaire on priority topics in mental health, the highest medians were identified in the "Depression" module. On the other hand, the content referring to the modules "Essential care and practices" and "Other important complaints" presented the lowest values. Furthermore, some participant characteristics were found to be associated with the percentage of correct answers in the questionnaire modules. CONCLUSIONS: The findings reveal opportunities for improvement, mainly in knowledge related to communication skills and the approach to emotional and physical distress without diagnostic criteria for a specific disease, offering support for planning actions aimed at intensifying the consideration of these themes during the operational stages of PAS.

Structural and functional analysis of Cyanovirin-N homologs: Carbohydrate binding affinities and antiviral potential of cyanobacterial peptides.

Cyanobacteria, a group of photosynthetic prokaryotes, can sinthesize several substances due to their secondary metabolism, with notable properties, such as Cyanovirin-N(CVN), a carbohydrate-binding lectin, that exhibits antiviral activity against several pathogens, due to its ability to bind viral surface carbohydrates such as mannose, thus interfering with the viral entry on the cell. CVN has been described in several cyanobacterial strains and shows biotechnological potential for the development of drugs of pharmaceutical interest. This study focuses on the genomic exploration and characterization of Cyanovirin-N homologs to assess the conservation of carbohydrate-binding affinity within the group. The analysis of their antiviral properties was carried out using bioinformatics tools to study protein models through an in silico pipeline, following the steps of genomic prospection on public databases, homology modeling, docking, molecular dynamics and energetic analysis. Mannose served as the reference ligand, and the lectins' binding affinity with mannose was assessed across Cyanovirin-N homologs. Genomic mining identified 33 cyanobacterial lectin sequences, which underwent structural and functional characterization. The results obtained from this work indicate strong carbohydrate affinity on several homologs, pointing to the conservation of antiviral properties alongside the group. However, this affinity was not uniformly distributed among sequences, exhibiting significant heterogeneity in binding site residues, suggesting potential multi-ligand binding capabilities on the Cyanovirin-N homologs group. Studies focused on the properties involved in these molecules and the investigation of the genetic diversity of Cyanovirin-N homologs could provide valuable insights into the discovery of new drug candidates, harvesting the potential of bioinformatics for large-scale functional and structural analysis.

Sitting leg vasculopathy: potential adaptations beyond the endothelium.

Increased sitting time, the most common form of sedentary behavior, is an independent risk factor for all-cause and cardiovascular disease mortality; however, the mechanisms linking sitting to cardiovascular risk remain largely elusive. Studies over the last decade have led to the concept that excessive time spent in the sitting position and the ensuing reduction in leg blood flow-induced shear stress cause endothelial dysfunction. This conclusion has been mainly supported by studies using flow-mediated dilation in the lower extremities as the measured outcome. In this review, we summarize evidence from classic studies and more recent ones that collectively support the notion that prolonged sitting-induced leg vascular dysfunction is likely also attributable to changes occurring in vascular smooth muscle cells (VSMCs). Indeed, we provide evidence that prolonged constriction of resistance arteries can lead to modifications in the structural characteristics of the vascular wall, including polymerization of actin filaments in VSMCs and inward remodeling, and that these changes manifest in a time frame that is consistent with the vascular changes observed with prolonged sitting. We expect this review will stimulate future studies with a focus on VSMC cytoskeletal remodeling as a potential target to prevent the detrimental vascular ramifications of too much sitting.

Essential oils on the control of fungi causing postharvest diseases in mango.

The use of fungicides in the postharvest treatment of mangoes has been widespread due to the incidence of pathogens, but awareness of the health risks arising from their use has increased, driving the search for more sustainable treatments. This study aimed to evaluate the activity of antifungal treatment of seven essential oils (EO) against four fungi that cause postharvest diseases in mangoes and define the minimum inhibitory concentration (MIC) and chemical composition, analyzed by gas chromatography (GC-MS). The results showed that the EOs of oregano, rosemary pepper, cinnamon bark, and clove inhibited 100% of the mycelial growth of the studied pathogens, with MIC ranging from 250 to 2000 µL.L-1. The main compound found in oregano was carvacrol (69.1%); in rosemary and pepper oil, it was thymol (77.2%); cinnamaldehyde (85.1%) was the main constituent of cinnamon bark, and the eugenol (84.84%) in cloves. When evaluating the antifungal activity of these compounds, thymol and carvacrol showed greater inhibitory activity against fungi. Therefore, this study showed the great potential of oregano, clove, rosemary pepper, and cinnamon bark essential oil as alternative treatments to synthetic fungicides in controlling postharvest diseases in mangoes.

Neuraminidase-induced externalization of phosphatidylserine activates ADAM17 and impairs insulin signaling in endothelial cells.

Endothelial insulin resistance represents a causal factor in the pathogenesis of type 2 diabetes (T2D) and vascular disease, thus the need to identify molecular mechanisms underlying defects in endothelial insulin signaling. We previously have shown that a disintegrin and metalloproteinase-17 (ADAM17) is increased while insulin receptor α-subunit (IRα) is decreased in the vasculature of patients with T2D, leading to impaired insulin-induced vasodilation. We have also demonstrated that ADAM17 sheddase activity targets IRα; however, the mechanisms driving endothelial ADAM17 activity in T2D are largely unknown. Herein, we report that externalization of phosphatidylserine (PS) to the outer leaflet of the plasma membrane causes ADAM17-mediated shedding of IRα and blunting of insulin signaling in endothelial cells. Furthermore, we demonstrate that endothelial PS externalization is mediated by the phospholipid scramblase anoctamin-6 (ANO6) and that this process can be stimulated by neuraminidase, a soluble enzyme that cleaves sialic acid residues. Of note, we demonstrate that men and women with T2D display increased levels of neuraminidase activity in plasma, relative to age-matched healthy individuals, and this occurs in conjunction with increased ADAM17 activity and impaired leg blood flow responses to endogenous insulin. Collectively, this work reveals the neuraminidase-ANO6-ADAM17 axis as a novel potential target for restoring endothelial insulin sensitivity in T2D.NEW & NOTEWORTHY This work provides the first evidence that neuraminidase, an enzyme increased in the circulation of men and women with type 2 diabetes (T2D), promotes anoctamin-6 (ANO6)-dependent externalization of phosphatidylserine in endothelial cells, which in turn leads to activation of a disintegrin and metalloproteinase-17 (ADAM17) and consequent shedding of the insulin receptor-α from the cell surface. Hence, this work supports that consideration should be given to the neuraminidase-ANO6-ADAM17 axis as a novel potential target for restoring endothelial insulin sensitivity in T2D.

Mulheres com síndrome do ovário policísticos que desenvolveram diabetes melitus 2 antes dos 35 anos: ansiedade, má qualidade do sono e não controle glicêmico / Women with polycystic ovarian syndrome who developed diabetes mellitus 2 before the age of 35: anxiety, poor sleep quality and lack of glycemic control / Mujeres con síndrome de ovario poliquístico que desarrollaron diabetes melitus 2 antes de los 35 años: ansiedad, mala calidad del sueño y sin control glucémico

Introdução: A síndrome dos ovários policísticos (SOP) consiste em uma desordem de origem endocrinológica de grande prevalência nas mulheres em idade fértil, sendo acometidas por ela aproximadamente de 6 a 16% da população feminina - em consonância com diversos critérios diagnósticos 1-4. Essa síndrome é associada ao hiperandrogenismo e à resistência insulínica (RI), com manifestações clínicas relacionadas a alterações reprodutivas 4, desenvolvimento de diabetes mellitus (DM2) e obesidade. Esta pesquisa objetiva compreender o perfil das mulheres com DM 2 antes dos 35 anos e os fatores que podem levar a esta condição. Metodologia: Este estudo se deu por meio de inquérito on-line feito a mulheres diagnosticadas com SOP, e com menos de 35 anos de idade. Foi desenvolvido de maneira virtualizada via plataforma GoogleForms® em função da pandemia do COVID-19. Tratou-se de um levantamento sobre presença de fatores de risco para DM 2, como sobrepeso e alimentação, sedentarismo e qualidade do sono; em grupos de mulheres com SOP diabéticas e não diabéticas, para efeito de comparação. Resultados e discussão: Um total de 198 mulheres responderam ao questionário, sendo divididas em Diabéticas (DM) e não diabéticas (NDM). O grupo DM foi o que mais apresentou IMC elevado (acima de 30), e o que mais se declarou seguir orientações nutricionais. Atividade física não diferenciou entre os grupos. O grupo DM foi o que declarou dormir mais tarde (pós 23:00) quando comparado com o grupo NDM. O sobrepeso indica ser um fator importante para o advento da DM 2 neste grupo, sendo as orientações nutricionais não tão efetivas, devido muito a dificuldade de aderir às orientações. O hábito de dormir tarde implica em alterações que levam a aumento da RI via estresse oxidativo, contribuindo para obesidade e DM 2. Conclusões: A obesidade é um fator decisivo para a precocidade da DM 2 em mulheres com SOP, e sua condição é multifatorial, associada a seguimento de orientações nutricionais, atividade física e qualidade do sono. O evitar da precocidade da DM 2 neste grupo passa por esta compreensão.

Introduction: Polycystic ovary syndrome (PCOS) is an endocrinological disorder with high prevalence in women of childbearing age, affected by approximately 6 to 16% of the female population - in line with several diagnostic criteria 1-4. This syndrome is associated with hyperandrogenism and insulin resistance (IR), with clinical manifestations related to reproductive changes 4, development of diabetes mellitus (DM2) and obesity. This research aims to understand the profile of women with DM 2 before the age of 35 and the factors that can lead to this condition. Methodology: This study was carried out through an online survey made to women diagnosed with PCOS, and under 35 years of age. It was developed in a virtualized way via the GoogleForms® platform due to the COVID-19 pandemic. This was a survey on the presence of risk factors for DM 2, such as overweight and diet, sedentary lifestyle and sleep quality; in groups of women with diabetic and non-diabetic PCOS for comparison purposes. Results and discussion: A total of 198 women answered the questionnaire, divided into Diabetic (DM) and non-diabetic (NDM). The DM group was the one with the highest BMI (above 30), and the one that most declared to follow nutritional guidelines. Physical activity did not differ between groups. The DM group was the one who reported sleeping later (after 11 pm) when compared to the NDM group. Overweight is an important factor for the advent of DM 2 in this group, and nutritional guidelines are not so effective, due to the difficulty in adhering to the guidelines. The habit of sleeping late implies changes that lead to increased IR via oxidative stress, contributing to obesity and DM 2. Conclusions: Obesity is a decisive factor for the precocity of DM 2 in women with PCOS, and its condition is multifactorial, associated with following nutritional guidelines, physical activity and sleep quality. Avoiding the precocity of DM 2 in this group involves this understanding.

Cenas Musicais na Associação de Pais e Amigos dos Excepcionais de São João Del-Rei (MG): uma Leitura Fenomenológica das Aulas de Musicalização para Crianças com Diversidade Funcional Intelectual / Music Scenes at the Association of Parents and Friends of Exceptional Children From São João Del-Rei (MG): a Phenomenological Approach of the Music Lessons for Children with Intelectual Functional Diversity

RESUMO: Este ensaio é fruto da experiência da primeira autora como educadora musical e coordenadora do Programa de Extensão "Música na Apae" da Universidade Federal de São João del-Rei, Minas Gerais. Apresentamos, aqui, algumas reflexões que deram origem à sua pesquisa de Doutorado, pautadas na abordagem fenomenológica, principalmente do filósofo Maurice Merleau-Ponty. A concepção fenomenológica de educação e a atitude mais aberta para enxergar a criança com Diversidade Funcional Intelectual [DFI] na sua expressividade musical genuína guiaram nosso olhar e orientaram as descrições das cenas aqui apresentadas, representando um momento de reflexão e, também, de autocrítica do educador, que está sempre em busca de meios, os quais possam ampliar a aprendizagem das crianças com DFI e torná-la mais significativa. Utilizamos o material de registro das aulas, como os diários de campo e gravações, que foram feitos para a documentação do desenvolvimento do Programa. Os resultados desse primeiro momento exploratório, como a potencialização da musicalidade e o desenvolvimento rítmico e da expressividade musical, indicam que um olhar mais atento ao fenômeno e ao sujeito em situação pode proporcionar uma aprendizagem musical mais significativa e mais adequada à maneira diversa de ser dessas crianças.

ABSTRACT: This essay is the result of the first author's experience as a music educator and coordinator of the Extension Program "Música na APAE" from the Universidade Federal de São João del-Rei, Minas Gerais, Brazil. Here, we present some reflections that have originated from her Doctoral research, based on the phenomenological approach, primarily influenced by the philosopher Maurice Merleau-Ponty. The phenomenological conception of education and a more open attitude toward perceiving children with Intellectual Functional Diversity [IFD] in their genuine musical expressiveness have guided our perspective and the scene descriptions presented, representing a moment of reflection and self-criticism for the educator who is always seeking means to enhance the learning of children with IFD and make it more meaningful. We used class registration material, such as field diaries and recordings, which were produced to document the development of the Program. The results of this initial exploratory phase, such as the enhancement of musicality, rhythmic development and musical expressiveness, indicate that a more attentive approach to the phenomenon and the individual in the situation can foster a more meaningful and appropriate musical learning experience to the diverse way of being of these children.

De Columbine a Suzano: uma análise sócio-histórica de atentados escolares / From Columbine to Suzano: a socio-historical analysis of school shootings / De Columbine a Suzano: un análisis sociohistórico de los ataques a escuelas / De Columbine à Suzano: une analyse socio-historique des attentats scolaires

Apesar dos 11 atentados escolares registrados no Brasil, os debates acadêmicos sobre o assunto ainda são escassos. O objetivo deste ensaio foi identificar as categorias histórico-sociais que permeiam a formação da singularidade dos infratores. Consultamos os materiais publicados pela mídia sobre os atentados brasileiros e as categorias encontradas na literatura internacional sobre o tema. Nossa análise fundamentou-se na perspectiva marxista, destacando as condições sociais, históricas e materiais nas quais os atentados ocorreram. Apontamos a socialização masculina, a relação com grupos de extrema direita e a reprodução da violência estrutural como configurações histórico-sociais fundamentais. Identificamos, também, que a destruição dos postos de trabalho e a assimilação da noção de indivíduo neoliberal agravam a cisão entre as dimensões coletivas e particulares, produzindo sujeitos que reproduzem a competitividade do mercado como régua para outras relações. O processo de precarização da escola pública a torna um alvo dos atentados, devido à ruptura que estabelece entre sujeito, educação e trabalho

Despite the eleven school shootings registered in Brazil, academic debate on the subject is still scarce. This essay sought to identify the historical-social categories that inform the offenders' singularity. We consulted media materials about the Brazilian shootings and the categories found in the international literature. Based on a Marxist analysis, we highlight the social, historical and material conditions of the attacks. Male socialization, association with far-right groups and reproduced structural violence emerge as fundamental historical-social configurations. Moreover, job precarization and the assimilation of the neoliberal individual aggravate the split between collective and private dimensions, producing subjects that use market competitiveness as a measure for other relations. The precarization of public school makes it a target of attacks due to the break it establishes between the subject, education and work

Se han registrado 11 ataques a escuelas en Brasil, pero todavía los debates académicos son escasos. El objetivo de este ensayo fue identificar las categorías históricas y sociales que median la formación de la singularidad de los infractores. Consultamos los materiales publicados por los medios de comunicación sobre los ataques brasileños y las categorías encontradas en la literatura internacional sobre el tema. Nuestro análisis se basó en la perspectiva marxista, destacando las condiciones sociales, históricas y materiales en las cuales ocurrieron los ataques. Apuntamos a la socialización masculina, la relación con los grupos de extrema derecha y la reproducción de la violencia estructural como las configuraciones histórico-sociales fundamentales. Identificamos también que la destrucción de las posibilidades de trabajo y la asimilación de la noción del individuo neoliberal agravan la separación entre las dimensiones colectivas y particulares, produciendo sujetos que reproducen la competitividad del mercado como regla para otras relaciones. El proceso de precarización de la escuela pública la pone en mira de los ataques, debido a la ruptura que hay entre sujeto, educación y trabajo

Malgré les onze attentats scolaires enregistrés au Brésil, le débat académique sur le sujet est encore rare. Cet essai a cherché à identifier les catégories socio-historiques qui informent la singularité des contrevenants. Nous avons consulté des documents médiatiques sur les attentats brésiliens et les catégories trouvées dans la littérature internationale. Sur la base d'une analyse marxiste, nous mettons en évidence les conditions sociales, historiques et matérielles des attentats. La socialisation masculine, l'association avec des groupes d'extrême droite et la violence structurelle reproduite apparaissent comme des configurations socio-historiques fondamentales. De plus, la précarisation du travail et l'assimilation de l'individu néolibéral aggravent le clivage entre les dimensions collectives et privées, produisant des sujets qui utilisent la compétitivité du marché comme mesure pour d'autres relations. La précarisation de l'école publique en fait une cible pour les attentats dû à la rupture qu'elle établit entre le sujet, l'éducation et le travail

In vitro evaluation of the activity of Cinnamaldehyde as an inhibitor of the biological cycle of Ctenocephalides felis felis.

The objective of this work was to evaluate the in vitro activity of cinnamaldehyde as an inhibitor of the biological cycle of Ctenocephalides felis felis. Tests were carried out with six repetitions containing 10 eggs of C. felis felis together with 0.5g of diet and filter paper discs with area of 23.76 cm2 impregnated with different concentrations of cinnamaldehyde (6; 8; 10; 12; 14; 16; 18; 20; 24 and 28 µg.cm-2) in Petri dishes and incubated in a climate-controlled chamber at 27 ± 1 °C and RH 75 ± 10%, for 30 days. The tests included a placebo group containing the diluent (acetone) and a negative control group, without treatment. At the end of 30 days, the percentage of inhibition of adult emergence/mortality was calculated, as well as the LC50 and LC90. Inhibition of adult emergence greater than 50% was observed from a concentration of 10 µg.cm-2 and 100% inhibition from a concentration of 14 µg.cm-2, obtaining LC50 and LC90 results of 8.75 and 13.57 µg.cm-2, respectively. We concluded that the volatile compound cinnamaldehyde is effective in vitro as an inhibitor of the biological cycle of C. felis felis.

O objetivo deste trabalho foi avaliar a atividade in vitro do cinamaldeído como inibidor do ciclo biológico de Ctenocephalides felis felis. Para realização do teste, seis repetições contendo 10 ovos de C. felis felis juntamente 0,5g de dieta e papel filtro de área 23,76 cm2 impregnado com diferentes concentrações de cinamaldeído (6; 8; 10; 12; 14; 16; 18; 20; 24 e 28 µg/cm2) foram armazenados em placas de petri e incubados em câmara climatizada à 27 ± 1°C e UR 75 ± 10%, por 30 dias. Além disso, o teste contou com um grupo placebo contendo o diluente (acetona) e um grupo controle negativo, sem tratamento. Ao final dos 30 dias, com os dados coletados foram calculados o percentual de inibição de emergência de adultos/mortalidade, como também a CL50 e CL90. Com os resultados, foi observado uma inibição de emergência de adultos superior a 50% a partir da concentração de 10 µg.cm-2 e uma inibição de 100% a partir da concentração 14 µg.cm-2 obtendo como resultados de CL50 e CL90 de 8,75 e 13,57 µg.cm-2, respectivamente. Conclui-se que o composto volátil cinamaldeído tem eficácia in vitro como inibidor do ciclo biológico de C. felis felis.

Deficiencies in reporting inclusion/exclusion criteria and characteristics of patients in randomized controlled trials of therapeutic interventions in pressure injuries: a systematic methodological review.

Wound care is a complex procedure and the related research may include many variables. Deficiencies in the sample inclusion and exclusion criteria may limit the generalizability of randomized controlled trials (RCTs) for wound patients in the real world. This study aimed to evaluate deficiencies in reporting the inclusion and exclusion criteria and the characteristics of patients in RCTs of pressure injuries (PI) therapeutic interventions. We conducted a systematic methodological review in which 40 full text RCTs of PI treatment interventions published in English, from 2008 to 2020, were identified. Data on the general characteristics of the included RCTs and data about inclusion/exclusion criteria and characteristics of patients were collected. The inclusion/exclusion criteria were categorized into five domains (definition of disease, precision, safety, ethical/legal and administrative). Study duration (in weeks) was 8.0 (quartile 1: 2.0; quartile 3: 48.0); only 5.0% of the trials mentioned race, skin colour or ethnicity, and 37.5% reported the duration of the wound. Only 9 (22.5%) studies reported the drugs that the included patients were using and 10 (25.0%) RCTs reported adverse events. The presence of the five domains was observed only in 12.5% of RCTs and only 12 (30.0%) had the precision domain. Much more research is required in systematic assessments of the external validity of trials because there is substantial disparity between the information that is provided by RCTs and the information that is required by clinicians. We concluded that there are deficiencies in reporting of data related to inclusion/exclusion criteria and characteristics of patients of RCTs assessing PI therapeutic interventions.

Molecular insights on the historical dispersion of Piezodorus guildinii (Hemiptera: Pentatomidae) in Brazil.

Piezodorus guildinii (Westwood, 1837) (Hemiptera: Pentatomidae) is an important arthropod pest of soybean (Glycine max (L.) Merr.) throughout American continents. However, the historical events associated with its dispersion are poorly understood. In this study, we employed a phylogeographic approach to investigate the origin and demographic history of P. guildinii in Brazil. We analyzed the cytochrome c oxidase subunit I and Cytb gene sequences of P. guildinii individuals collected in Brazil's 5 soybean production macro-regions and cross-referenced this information with sequences available in public databases. Our findings support an older Caribbean basin establishment for the current genealogical strains of P. guildinii, with subsequent dispersion to Brazil around 0.97 Mya. No secondary dispersion of this species from the Caribbean region to soybean areas in Brazil was identified. The Brazilian populations of P. guildinii are genetically structured across the country's soybean macro-regions and show strong signals of continuous demographic and spatial expansion in Brazil, which may be accelerated by the soybean cropping landscape in the country. The populations from the northern region (MR5) are older than the Central and South populations. The signs of demographic expansion indicate that P. guildinii populations are increasing their effective size in soybean regions, which could reflect its importance as a soybean pest in the coming years.

Nutritional support in palliative cancer care: quality of life in oral versus tube feeding.

BACKGROUND: Nutritional support (NS) offered through oral nutritional supplements (ONS) or enteral nutrition (EN) and its impact on quality of life (QoL) is a controversial topic in patients with cancer receiving palliative care (PC). AIMS: To compare the QoL of patients without and with use of NS, including ONS or EN in patients with incurable cancer receiving PC. METHODS: Cross-sectional analysis with patients that were evaluated at PC Unit between June 2021 and February 2023. QoL was assessed using the Quality of Life Questionnaire Core 15. Patients were classified into three groups according to the NS: ONS (n=72; 33%), EN (n=61; 28%) and control group (CG) (n=87; 39%), the last one being formed by patients not using NS. Adjusted logistic regression models were used to verify the association of the domains of QoL with the type of NS. RESULTS: A total of 220 patients were included, with a median age of 64 (58-70) years, predominantly male (54.1%). The EN group had worse scores in physical function when compared with the ONS group (p=0.037) and appetite loss when compared with the CG (p=0.013). The ONS (OR: 2.70; 95% CI 1.32 to 5.49) and EN groups (OR: 2.61; 95% CI 1.24 to 5.49) were independently associated with a higher chance of presenting appetite loss in relation to the CG. CONCLUSION: In general, there was no difference in the QoL of patients using NS when compared with patients not using NS. However, patients using NS have more chance of having appetite loss.

Larvicidal activity in vitro of essential oils against Cochliomyia hominivorax.

Cochliomyia hominivorax, from the family Calliphoridae, is responsible for causing most myiases in domesticated animals in Brazil. As alternatives to conventional treatments, essential oils (EOs) could possibly be used as natural control of ectoparasites. The aim of this study was to evaluate the in vitro activity of EOs from Salvia sclarea L., Rosmarinus officinalis L., Lavandula hybrida Reverchon, Citrus bergamia Risso, Citrus paradisi L., Juniperus virginiana L., Copaifera reticulata Ducke, Illicium verum Hook f., Pelargonium roseum, Cymbopogon winterianus Jowitt, Cymbopogon flexuosus Steud, Eugenia caryophyllus Spreng, Cinnamomum cassia Presl, Thymus vulgaris L. and Origanum vulgare L. against third-instar larvae of C. hominivorax. To evaluate the mortality rate, filter paper tests were performed at different concentrations and verified after 24 h and 48 h. Essential oils of T. vulgaris, O. vulgare and I. verum induced 100% mortality in the screening test, and their main active components (thymol, carvacrol and anethol, respectively) were also tested alone. In this new test, lethal concentrations (LC50) after 24 h and 48 h, respectively, were 407.1 and 314.2 µg.cm-² for T. vulgaris, 540.9 and 253.8 µg.cm-² for O. vulgare, 314.2 µg.cm-² (after 48 h) for I. verum, 255.6 and 102.3 µg.cm-² for thymol, 970.5 and 931.1 µg.cm-2 for carvacrol and 559.4 µg.cm-2 (after 48 h) for anethol. These results showed the potential of these EOs and their main components for development of ectoparasiticides for veterinary use, especially T. vulgaris EO and thymol.

Evaluation of the Training Session in Elite Paralympic Powerlifting Athletes Based on Biomechanical and Thermal Indicators.

BACKGROUND: Paralympic powerlifting (PP) is performed on a bench press, aiming to lift as much weight as possible in a single repetition. PURPOSE: To evaluate thermal asymmetry and dynamic force parameters with 45 and 80% 1 Repetition Maximum (1 RM) in PP athletes. METHODS: Twelve elite PP male athletes were evaluated before and after a training session regarding skin temperature (thermography) and dynamic force indicators (Average Propulsive Velocity-MPV, Maximum Velocity-VMax, and Power). The training consisted of five series of five repetitions (5 × 5) with 80% 1 RM. The force indicators and dynamics before and after (45% 1 RM) were evaluated in series "1" and "5" with 80% 1 RM. RESULTS: The temperature did not present asymmetry, and there were differences between the moment before and after. In MPV, Vmax, and Power, with 45% 1 RM, there were differences both in asymmetry and in moments (p < 0.005). With 80% 1 RM, asymmetry was observed, but no differences between moments (p < 0.005). CONCLUSION: No thermal asymmetry was observed. There were reductions in MVP and VMax at 45 and 80% 1 RM but without significant differences between time points (before and after). However, there was asymmetry in the moments before and after within a safety standard, where Paralympic powerlifting was safe in terms of asymmetries.
