ABSTRACT Overcoming malnutrition in all its forms, which is also manifested in the obesity epidemic, is one of the priorities of the 2030 Agenda and the Sustainable Development Goals. This article presents reflections on food insecurity in Brazil, based on topics such as population growth, climate change, biodiversity and traditional and regenerative food systems; it also addresses the role of social initiatives to guarantee the Human Right to Adequate Food. The Nutrition and Poverty Research Group, Planetary Health - Brazil Group, and the Center for Artificial Intelligence (C4AI) - AgriBio Axis, assume that the organized and systemic resumption of the initiatives mentioned out in this position paper can contribute to the articulation between research, public policies and services, to combat all forms of malnutrition, as a complex and priority problem to ensure social welfare.

RESUMO O combate à má alimentação em todas as suas formas, que também se expressa na epidemia da obesidade, é uma das prioridades da Agenda 2030 e dos Objetivos de Desenvolvimento Sustentável. Este artigo traz elementos sobre insegurança alimentar no Brasil, a partir de temas relativos ao crescimento populacional, mudanças climáticas, biodiversidade e sistemas alimentares tradicionais e regenerativos; trata também do papel dos movimentos sociais para a garantia do Direito Humano à Alimentação Adequada. O Grupo de Pesquisa em Nutrição e Pobreza, o Saúde Planetária Brasil, e o Centro de Inteligência Artificial (C4AI) - Eixo AgriBio, entendem que a retomada organizada e sistêmica das frentes apontadas neste artigo de posicionamento, pode constituir um caminho para a articulação entre pesquisa, serviço e políticas públicas na direção do combate à fome e às demais manifestações da má alimentação, enquanto problema complexo prioritário para a garantia do bem-estar social.

Resumo Introdução: Ao acompanhar a pessoa com câncer durante a hospitalização, o familiar ou cuidador pode carregar consigo o sofrimento dela, assumindo responsabilidades frente às suas necessidades físicas e emocionais. Esta experiência pode gerar desgaste devido à sobrecarga gerada pelo estresse que envolve a situação de doença e internação. Objetivos: Compreender a percepção de familiares e cuidadores sobre sua saúde emocional ao acompanhar o paciente com câncer no hospital; delinear as estratégias utilizadas por eles para promover o autocuidado emocional. Método: Estudo descritivo-exploratório, qualitativo, realizado em um hospital privado extra porte na cidade de São Paulo, Brasil. A amostra constituiu-se por 15 familiares e três cuidadores de pacientes com câncer hospitalizados. A coleta de dados realizou-se por meio de entrevista semiestruturada, utilizando-se a Análise Temática de Conteúdo, de Bardin, para análise dos dados. Resultados: Os discursos evidenciam a vivência de quem assume o papel de acompanhar a pessoa com câncer, tendo que lidar com as dificuldades que se apresentam no hospital e ser, ao mesmo tempo, a fonte de força para essa pessoa, além da mudança em sua rotina de vida devido as internações frequentes. Todavia, com o passar do tempo, sentem-se mais tranquilos e confiantes em assumir o papel de acompanhante, buscando estratégias que promovam o próprio cuidado emocional, como apoio religioso, prática de esportes e hobbies, meditação, yoga, atendimento psicológico, assistir televisão, ler e ouvir música, estudar e trabalhar online, entre outras. Considerações finais: Para enfrentar a sobrecarga física e emocional ao acompanhar o paciente com câncer, familiares/cuidadores utilizam várias iniciativas que favorecem o autocuidado emocional. Instituições de saúde devem promover o suporte necessário para que estas estratégias sejam valorizadas e incorporadas no cotidiano dessas pessoas que assumem o papel de acompanhante.

Abstract Introduction: When accompanying the person with cancer during hospitalization, the family member or caregiver can carry their suffering with them, taking responsibility for their physical and emotional needs. This experience can generate exhaustion due to the overload generated by the stress that involves the illness and hospitalization situation. Objectives: To understand the perception of family members and caregivers about their emotional health when accompanying a cancer patient in the hospital; outline the strategies used by them to promote emotional self-care. Method: Descriptive-exploratory, qualitative study, carried out in an extra-sized private hospital in the city of São Paulo, Brazil. The sample consisted of 15 family members and three caregivers of hospitalized cancer patients. Data collection was carried out through semi-structured interviews, using Bardin's Thematic Content Analysis for data analysis. Results: The speeches show the experience of those who assume the role of caring for the person with cancer, having to deal with the difficulties that arise in the hospital and, at the same time, being the source of strength for that person, in addition to the change in their routine of life due to frequent hospitalizations. However, over time, they feel calmer and more confident in assuming the role of companion, seeking strategies that promote their own emotional care, such as religious support, practice of sports and hobbies, meditation, yoga, psychological care, watching television, read and listen to music, study and work online, among others. Final considerations: To face the physical and emotional overload when accompanying the cancer patient, family members/caregivers use several initiatives that favor emotional self-care. Health institutions must provide the necessary support so that these strategies are valued and incorporated into the daily lives of these people who assume the role of companions.

ABSTRACT Mangrove ecosystems are sensitive to oil, as spills can impair developmental processes of mangrove vegetation. Since the 2010s, the Brazilian equatorial margin, more specifically the Pará-Maranhão Basin and the mouth of the Amazonas River, has been affected by oil runoff from urban activities and the increased risk from exploratory deepwater drilling for oil extraction. Dispersal of mangrove propagules occurs during the tidal cycles, when the presence of tensors in the water can affect germination. We analyzed the effects of diesel oil on the germination of propagules of the two most common mangrove species in the region, Laguncularia racemosa and Avicennia germinans, in six treatments of diesel oil in the water (0.5%, 1%, 1.5%, 2%, 3% and 4%) and a diesel-free control. The response variables were germinability (G%), mean germination time, mean germination speed and the germination speed index (GSI). G% and GSI in L. racemosa propagules differed significantly between the control and all treatments (G% and GSI < 10% in the 3% treatment). Propagules of A. germinans were more resistant, and the physiological variables did not differ significantly among treatments and control (G% > 90% in all treatments). Our results indicate that, at the germination stage, L. racemosa was more susceptible than A. germinans to contamination by automotive diesel oil.

RESUMO Os ecossistemas de manguezais são sensíveis ao óleo, pois os derramamentos podem prejudicar os processos de desenvolvimento da vegetação de mangue. Desde a década de 2010, a margem equatorial brasileira, mais especificamente a Bacia do Pará-Maranhão e a foz do Rio Amazonas, vem sendo afetada pelo vazamento de petróleo proveniente de atividades urbanas e pelo aumento do risco de perfurações exploratórias em águas profundas para extração de petróleo. A dispersão dos propágulos do manguezal ocorre durante os ciclos das marés, quando a presença de tensores na água pode afetar a germinação. Analisamos os efeitos do óleo diesel na germinação de propágulos de duas espécies de mangue mais comuns na região, Laguncularia racemosa e Avicennia germinans, em seis tratamentos de óleo diesel na água (0,5%, 1%, 1,5%, 2%, 3% e 4%) e um controle sem óleo diesel. As variáveis resposta foram germinabilidade (G%), tempo médio de germinação, velocidade média de germinação e índice de velocidade de germinação (IVG). G% e IVG dos propágulos de L. racemosa diferiram significativamente entre o controle e todos os tratamentos (G% e GSI < 10% no tratamento 3%). Os propágulos de A. germinans foram mais resistentes e as variáveis fisiológicas não diferiram significativamente entre tratamentos e controle (G% > 90% em todos os tratamentos). Nossos resultados indicam que, no estágio de germinação, L. racemosa foi mais suscetivel que A. germinans à contaminação por óleo diesel automotivo.

ABSTRACT Tifton 85 bermudagrass has been widely used in tropical and subtropical regions. Owing to its high forage yield, the fertilizer requirement of Tifton 85 is also high. Inoculation with Azospirillum brasilense is an alternative to reduce the use of nitrogen fertilizers and decrease their environmental impact. However, the effects of inoculation in tropical grasses remain poorly understood. This study aimed to evaluate the productivity, pasture characteristics, and nutritive value of Tifton 85 bermudagrass inoculated with A. brasilense in association with nitrogen fertilization. The study evaluated four nitrogen levels (0, 100, 200, and 300 kg ha-1 ), inoculated and uninoculated, under cutting conditions. The experimental design was completely randomized, in a factorial arrangement, with two qualitative (inoculated with A. brasilense or uninoculated) and four quantitative levels (nitrogen doses) with three replications (24 plots). Botanical composition and morphological characteristics, leaf blade/stem+sheath ratio, nutritive value, and forage yield were evaluated. The inoculation increased the leaf blade/stem+sheath ratio and forage yield of Tifton 85, but did not affect crude protein concentration, neutral detergent fiber content, and total digestible nutrient content of the forage constituted by Tifton 85 leaf blades. The protein concentration and forage production corresponded linearly to the nitrogen dose increase.

Abstract This research aimed to produce and evaluate particleboard with pinus waste using two production methodologies. One applied to homogeneous panels (single layer) and another to heterogeneous panels (three layers). The panels were produced with an initial density of 0.550 g/cm³, with 10% polyurethane resin derived from castor oil (PUR) for the homogeneous panels and 12% for the heterogeneous ones. The pressing parameters were 5 MPa, with a temperature of 100 ºC and 10 min of pressing, with an interval of 30 s. The tests performed according to NBR 14810-2 (ABNT, 2018) standard. As a result, it was observed that the reorganization of the particles of the heterogeneous panels added to the increase of the adhesive were factors that improved the final properties of the panels, which are classified to be used as decoration objects and in the furniture industry, not obtaining classification of homogeneous panels.

Resumo Esta pesquisa teve como objetivo produzir e avaliar painéis aglomerados com resíduo de pinus medianteuma metodologia de produçãoaplicada para painéis homogêneos e outra para heterogêneos. Os painéis homogêneos e heterogêneos foram produzidos com densidade inicial de 0,550 g/cm³ e com 10% e 12% de resina de poliuretano derivado do óleo de mamona (PUR) respectivamente. Os parâmetros de prensagem foram de 5 MPa, com temperatura de 100 ºC e 10 min de prensagem, com um intervalo de 30 s. Os ensaios realizados seguiram a normativa NBR 14810-2 (ABNT, 2018). Observou-se que a reorganização das partículas dos painéis heterogêneos somada ao aumento do adesivo foram fatores que melhoraram as propriedades finais desses painéis, classificados para ser utilizados como objetos de decoração e na indústria moveleira, enquanto os painéis homogêneos não obtiveram classificação.

ABSTRACT Colorectal cancer (CRC) is among the most diagnosed malignancies worldwide, and it is also the second leading cause of cancer-related deaths. Despite recent progress in screening programs, noninvasive accurate biomarkers are still needed in the CRC field. In this study, we evaluated and compared the urinary proteomic profiles of patients with colorectal adenocarcinoma and patients without cancer, aiming to identify potential biomarker proteins. Urine samples were collected from 9 patients with CRC and 9 patients with normal colonoscopy results. Mass spectrometry (label-free LC—MS/MS) was used to characterize the proteomic profile of the groups. Ten proteins that were differentially regulated were identified between patients in the experimental group and in the control group, with statistical significance with a p value ≤ 0.05. The only protein that presented upregulation in the CRC group was beta-2-microglobulin (B2M). Subsequent studies are needed to evaluate patients through different analysis approaches to independently verify and validate these biomarker candidates in a larger cohort sample.

Abstract To assess the in vitro and in situ effect of experimental combined fluoride and calcium nanocomposite solutions on dental caries prevention. Nanocompound mesoporous silica (MS) with calcium (Ca) and sodium fluoride (NaF) - (MSCaNaF); MS with NaF (MSNaF), NaF solution (positive control), and deionized water (negative control - CG) were studied. The specimens (n=130) were submitted in vitro to a multispecies biofilm in the presence of 2% sucrose. After 24 h and 48 h, the culture medium pH, the percent of surface mineral loss (%SML), and lesion depth (ΔZ) were analyzed. In the in situ study, 10 volunteers participated in four phases of 7-days each. The products were applied on the specimens (n=240) before 20% sucrose solution drips. The polysaccharides (SEPS and IEPS), %SML and roughness (Sa) were evaluated. There was an in vitro decrease in pH values in 24h and 48h, compared to baseline. The MSCaNaF and MSNaF groups obtained lower values of %SML and ΔZ (p < 0.05) than CG and NaF after 24h and were similar to NaF after 48h (p<0.05). In situ results showed similar SEPS and IEPS among all groups after 48h. An after 7-days, the nanocomposites had similar values (p>0.05), while NaF was similar to CG (p>0.05). After 48h, the MSCaNaF and MSNaF reduced the %SML (p<0.05). After 7-days, both experimental nanocomposites were similar to NaF (p>0.05). Regarding Sa, MSCaNaF was better than NaF for both periods (p<0.05). The nanocomposites controlled the in vitro and in situ enamel demineralization, mainly in the initial periods.

This is a multicenter, cross-sectional study carried out with students regularly enrolled in undergraduate courses at eight Brazilian IFES. Data collection was conducted between October 2021 and February 2022 using an online self-completed questionnaire, which addressed sociodemographic and academic characteristics, lifestyle habits, and health conditions. Symptoms of anxiety and depression were assessed using the Depression, Anxiety, and Stress Scale-21 (DASS-21). Variables were analyzed descriptively using frequency distribution and Pearson’s chi-square test. To estimate the prevalence of symptoms of anxiety and depression, the proportion and 95% confidence interval (95%CI) were used. The level of adopted statistical significance was 5%.

RESUMO As Síndromes Hipertensivas da Gestação (SHG) são uma das principais causas de morbimortalidade materna. Evidências crescentes indicam a associação entre a exposição ao cádmio e a hipertensão arterial na população em geral, mas não as SHG. Afim de investigar esse tema, realizou-se uma revisão sistemática seguindo as diretrizes PRISMA, nas bases de dados BVS/Lilacs, PubMed/Medline e SciELO e no repositório da Universidade de São Paulo (USP) até agosto de 2021. A qualidade metodológica foi avaliada pelo checklist Downs and Black. Selecionaram-se dezenove artigos, sendo treze caso-controle, quatro coortes e dois seccionais. No total, 11.451 participantes foram avaliadas, sendo 1.445 (12,6%) com SHG e, destas, 1.071 (74,1%) com pré-eclâmpsia. Observou-se o ajuste inadequado para confundimento em onze estudos. Dos sete estudos considerados de boa qualidade metodológica, quatro relataram associação positiva e três não a observaram, enquanto somente um estudo observou diferença de média, que foi maior nas gestantes com SHG. Atribuiu-se a divergência dos resultados às diferenças metodológicas e ao ajuste inadequado para os fatores de confusão. Como o cádmio é um metal tóxico que pode levar ao aumento do estresse oxidativo, que desempenha papel importante na fisiopatologia das SHG, estudos adicionais são necessários para elucidar esta associação.

ABSTRACT Hypertensive Disorders of Pregnancy (HDP) are one of the main causes of maternal morbimortality. Strong evidence point to an association between cadmium and hypertension in the general population, but not HDP. A systematic review was carried out to investigate this potential relationship, following PRISMA guidelines, in the BVS/LILACS, PubMed/MEDLINE, and SciELO databases and a repository (University of São Paulo – USP) until August 2021. The methodological quality was assessed using the Downs and Black checklist. Nineteen articles were selected, thirteen of which were case-control, four were cohorts, and two were cross-sectional. A total of 11.451 participants were evaluated, 1.445 (12.6%) with HDP, and of these 1.071 (74.1%) with preeclampsia. The inadequate adjustment for confounding was observed in eleven studies. Out of the seven studies considered good methodological quality, four reported a positive association, and three did not observe it. In contrast, only one observed a mean difference, which was higher in HDP. The inconsistency of the results was attributed to the methodological differences and inadequate adjustment for confounding. As cadmium is a toxic metal that can induce an increase in oxidative stress, which plays an essential role in the pathophysiology of HDP, additional studies are needed to elucidate this association.

Resumo O objetivo deste artigo é sintetizar artigos que abordam fake news e hesitação vacinal contra a COVID-19 no contexto de saúde pública. Revisão integrativa que incluiu estudos originais indexados nas bases de dados Literatura Latino Americana e do Caribe em Ciências da Saúde; Medical Literature Analysis and Retrieval System Online; Scopus; Web of Science e Embase, publicados em qualquer idioma, entre 2019 e 2022. A análise crítica foi realizada na forma descritiva, consoante à pergunta de pesquisa e ao objetivo da revisão. Foram selecionados 11 artigos, com predomínio de estudos transversais. Relacionaram-se ao processo de adesão à vacinação: gênero, idade, estado civil, escolaridade, posicionamento político, religião, confiança em autoridades de saúde, percepção de efeitos colaterais e eficácia das vacinas, entre outros. Hesitação e desinformação são os principais entraves para se alcançar a cobertura vacinal em muitos países. Todos os estudos abordam a relação entre baixa intenção de imunização e uso de mídias sociais como fonte de informação sobre o SARS-CoV-2. É necessário aumentar a confiança na segurança e eficácia das vacinas. A melhor compreensão dos benefícios da vacinação para COVID-19 é imprescindível para combater a hesitação e ampliar a adesão vacinal.

Abstract This article aims to synthesize articles addressing fake news and COVID-19 vaccine hesitancy in the context of public health. We conducted an integrative review of articles published in any language between 2019 and 2022 in journals indexed in the following databases: Latin American and the Caribbean Literature on Health Sciences, Medical Literature Analysis and Retrieval System Online, Scopus, Web of Science, and Embase. A critical analysis was performed, guided by the research question and objective of the review. Eleven articles were selected, the overwhelming majority of which were cross-sectional studies. The main factors related to vaccine take-up highlighted by the studies were gender, age, education level, political leanings, religion, trust in health authorities, and perceptions of side-effects and vaccine efficacy. The main obstacles to attaining optimal vaccination coverage were vaccine hesitancy and disinformation. All studies addressed the relationship between low vaccination intention and the use of social media as a source of information about SARS-CoV-2. It is necessary to build public trust in vaccine safety and efficacy. Promoting a better understanding of the benefits of COVID-19 vaccination is essential to combat vaccine hesitancy and improve vaccine take-up.

Abstract The present study examines sex differences regarding children’s self-perceptions and motor competence (locomotor and object control subtests), parents’ perceptions about their boys’ and girls’ competence, and the associations among these variables. Parents and their children (N= 77; M= 8.70, SD= 2.13) participated in the study. The children’s motor competence was assessed using the Test of Gross Motor Development — Second Edition (TGMD-2). The children’s self-perceptions were assessed using the Pictorial Scale of Perceived Competence and Social Acceptance and the Self-Perception Profile for Children, depending on the child’s age. The parental perception of their children’s motor competence was assessed using an adapted version of the children’s perceptions of motor competence. Boys and girls were similar regarding the locomotor subtest; boys showed significantly higher scores for the object control subtest than girls. Parents’ perceptions of children’s motor competence were significantly related to the children´s motor competence and were the stronger predictor in the locomotor model and the second predictor in the object control subtest model; sex was the stronger predictor for the object control subtest. Our findings address new information regarding children’s motor and parents’ motor competence.

ABSTRACT BACKGROUND: Sarcopenia is defined as a slow, progressive, and apparently inevitable process of involuntary loss of muscle mass, strength, and quality, which occurs with advancing age. It is widely accepted that sarcopenia can directly affect quality of life. OBJECTIVE: Translate, adapt and validate the “Sarcopenia and Quality of Life” instrument (SarQoL) to the Brazilian context. DESIGN AND SETTINGS: Translation, cross-cultural adaptation, and validation study carried out at the Federal University of São Carlos, São Carlos, São Paulo, Brazil. METHODS: The population consisted of 221 older adult participants. The steps recommended by the guidelines from the authors of the original instrument were followed sequentially: initial translation, synthesis of translations, backward translation, evaluation by a panel of judges, pre-test, and analysis of psychometric properties. The translation and adaptation process was conducted as recommended. RESULTS: Two hundred and twenty-one participants took part in the step analysis of the psychometric properties of SarQoL, in which 55 presented sarcopenia. Cronbach's alpha coefficient of the total SarQoL questionnaire was 0.976, indicating excellent internal consistency. Excellent agreements between the test and retest with an Interclass Correlation Coefficient (ICC) of 0.983 (95% confidence interval: 0.901–0.996) were observed in the SarQoL domains. The domains of Short-Form 36 and EuroQoL 5-dimension showed significant correlation, from moderate to strong magnitude, with SarQoL total score, indicating convergent validity. CONCLUSION: The Brazilian version of SarQoL presented evidence of reliability and validity.
