Abstract Background: Real-world, primary data on the treatment of psoriasis are scarce, especially concerning the role of soluble biomarkers as outcome predictors. Objective: The authors evaluated the utility of Th1/Th17 serum cytokines along with clinical characteristics as predictors of drug survival in the treatment of psoriasis. Methods: The authors consecutively included participants with moderate to severe psoriasis who were followed up for 6 years. Baseline interferon-α, tumor necrosis factor-α, and inter-leukin (IL)-2, IL-4, IL-6, IL-10, and IL-17A were measured using a cytometric bead array; clinical data were assessed. The authors calculated hazard ratios (HRs) for drug survival using a Cox proportional hazards model. Results: The authors included 262 patients, most of whom used systemic immunosuppressants or biologics. In the multivariate model, poor quality of life measured by the Dermatology Life Quality Index (HR = 1.04; 95% CI 1.01–1.07; p = 0.012) and elevated baseline IL-6 (HR = 1.99; 95% CI 1.29–3.08; p = 0.002) were associated with treatment interruption. Study limitations: The main limitation of any cohort study is the presence of confounders that could not be detected in clinical evaluation. Conclusions: Poor quality of life and elevated baseline serum IL-6 level predicted treatment interruption in patients with moderate to severe psoriasis. Although IL-6 is not the most important mediator of the inflammatory pathway in the skin environment, it is an interesting biomarker candidate for predicting psoriasis treatment response.

Abstract Objective We aim to describe an experimental model for studying femoral fractures in rats after exposure to ionizing radiation, demonstrating a way to apply a substance for analysis, the method for patterning fracture and irradiation, and how to evaluate its effectiveness based on radiographic studies. Methods We used 24 rats divided into 2 groups of 12 animals each. The STUDY group was exposed to ionizing radiation and treated with saline solution, and the CONTROL group was not exposed to radiation and was treated with saline solution. All animals were subjected to standardized fracture of the right femur that was fixed with intramedullary wire. The efficiency of the bone union was assessed by radiographic exam. Results Fracture healing was more efficient in bones not exposed to ionizing radiation (p = 0.012). All fractures met the criteria of being simple, diaphyseal, transverse or short oblique. Conclusion The experimental model presented is an efficient alternative for the study of fractures in irradiated bones in rats.

Resumo Objetivo Nosso objetivo é descrever um modelo experimental para estudo de fraturas de fêmur em ratos após exposição a radiação ionizante, demonstrando uma forma de aplicação de uma substância para análise, o método de padronização de fratura e irradiação e a forma de avaliação de sua eficácia com base em estudos radiográficos. Métodos Utilizamos 24 ratos divididos em dois grupos de 12 animais cada. O grupo ESTUDO foi exposto à radiação ionizante e tratado com soro fisiológico, enquanto o grupo CONTROLE não foi exposto à radiação e foi tratado com soro fisiológico. Todos os animais foram submetidos à fratura padronizada do fêmur direito e sua fixação com fio intramedular. A eficácia da consolidação óssea foi determinada por exame radiográfico. Resultados A cicatrização de fraturas foi mais eficiente em ossos não expostos à radiação ionizante (p = 0,012). Todas as fraturas atenderam aos critérios de serem simples, diafisárias, transversas ou oblíquas curtas. Conclusão O modelo experimental apresentado é uma boa alternativa para o estudo de fraturas em ossos irradiados em ratos.

Abstract Background Professional soccer athletes are exposed to repetitive head impacts and are at risk of developing chronic traumatic encephalopathy. Objective To evaluate regional brain glucose metabolism (rBGM) and gray matter (GM) volume in retired soccer players (RSPs). Methods Male RSPs and age and sex-matched controls prospectively enrolled between 2017 and 2019 underwent neurological and neuropsychological evaluations, brain MRI and [18F]FDG-PET in a 3.0-Tesla PET/MRI scanner. Visual analysis was performed by a blinded neuroradiologist and a blinded nuclear physician. Regional brain glucose metabolism and GM volume were assessed using SPM8 software. Groups were compared using appropriate statistical tests available at SPM8 and R. Results Nineteen RSPs (median [IQR]: 62 [50–64.5] years old) and 20 controls (60 [48–73] years old) were included. Retired soccer players performed worse on mini-mental state examination, digit span, clock drawing, phonemic and semantic verbal fluency tests, and had reduced rBGM in the left temporal pole (pFDR = 0.008) and the anterior left middle temporal gyrus (pFDR = 0.043). Semantic verbal fluency correlated with rBGM in the right hippocampus, left temporal pole, and posterior left middle temporal gyrus (p ≤ 0.042). Cray matter volume reduction was observed in similar anatomic regions but was less extensive and did not survive correction for multiple comparisons (pFDR ≥ 0.085). Individual [18F]FDG-PET visual analysis revealed seven RSPs with overt hypometabolism in the medial and lateral temporal lobes, frontal lobes, and temporoparietal regions. Retired soccer players had a higher prevalence of septum pellucidum abnormalities on MRI. Conclusion Retired soccer players had reduced rBCM and CM volume in the temporal lobes and septum pellucidum abnormalities, findings possibly related to repetitive head impacts.

Resumo Antecedentes Jogadores profissionais de futebol estão expostos a impactos cranianos repetitivos e ao risco de desenvolver encefalopatia traumática crônica. Objetivo Avaliar o metabolismo glicolítico cerebral regional (MCCr) e o volume de substância cinzenta (vSC) em jogadores de futebol aposentados (JFAs). Métodos Jogadores de futebol aposentados masculinos e controles pareados por idade e sexo foram incluídos prospectivamente entre 2017 e 2019. Foram realizadas avaliações neurológica e neuropsicológica, ressonância magnética (RM) e [18F]FDG-PET cerebrais (3.0-Tesla PET/RM). As imagens foram analisadas visualmente por um neurorradiologista e um médico nuclear cegos ao grupo de cada participante. O metabolismo glicolítico cerebral regional e o vSC foram avaliados através do programa SPM8. Os grupos foram comparados através de testes estatísticos apropriados disponíveis em SPM8 e R, de acordo com a distribuição e o tipo dos dados. Resultados Dezenove JFAs (mediana [IIQ]: 62 [50–64.5] anos) e 20 controles (60 [48–73] anos) foram incluídos. Os JFAs tiveram pior desempenho no mini-exame do estado mental e nos testes de dígitos, desenho do relógio, fluência verbal e fluência semântica e apresentaram MCCr significativamente reduzido no polo temporal e no giro temporal médio anterior esquerdos. Fluência semântica (animais) apresentou correlação positiva com MCCr no hipocampo direito, no polo temporal esquerdo e no aspecto posterior do giro temporal médio esquerdo. Menor vSC foi observado nas mesmas regiões, porém este achado não sobreviveu à correção para comparações múltiplas. Análise individual do [18F]FDG-PET cerebral revelou sete JFAs com claro hipometabolismo nas faces medial e lateral dos lobos temporais, nos lobos frontais e nas regiões temporoparietais. Os JFAs apresentaram ainda maior prevalência de anormalidades do septo pelúcido. Conclusão Os JFAs apresentam MCCr e vSC reduzidos nos lobos temporais, além de anormalidades do septo pelúcido, achados possivelmente relacionados a impactos cranianos repetitivos.

Abstract The present work intends to carry out a bibliometric analysis of the concept of burnout, taking into account the professions most related to health care. or this, a search was carried out on the Web Of Science (WoS) for the time period 01/01/2017 - 03/02/2022, delimiting it to professions related to health care services. An attempt was made to characterize burnout research in areas related to health, taking into account the authors, co-authorships, affiliations, nationalities, the area of knowledge of each professional, their scientific impact and the keywords used. The research was subsequently analyzed using two bibliometric instruments, VOSviewer by Van Eck and Waltman (2010; 2022) and HistCite by Garfield (2009). We highlight the emergence of studies signed by professionals themselves in journals related to their areas, which seems to point towards dimensions related to self-care being an integral part of professional practice. In terms of emerging themes, those related to COVID-19 emerge, as well as keywords related to mental health and resilience. Themes more centered on work performance have an older average time of publication. We also note that keywords related to new technologies are practically absent in our research, which could point to an area of investigation still to be explored.

Resumo O presente trabalho pretende fazer uma análise bibliométrica do conceito de burnout, levando em linha de conta as profissões mais relacionadas com os cuidados de saúde. Para isso, procedeu-se a uma pesquisa na Web Of Science (WoS) para o período temporal 01/01/2017 - 02/03/2022, delimitando-a a profissões relacionadas aos cuidados e serviços de saúde. Procurou-se caracterizar a investigação em burnout nas áreas relacionadas com a saúde considerando os autores, as coautorias, as afiliações, as nacionalidades, a área de conhecimento de cada profissional, o seu impacto científico e as palavras-chave utilizadas. A pesquisa foi posteriormente analisada através de dois instrumentos bibliométricos, o VOSviewer de Van Eck e Waltman (2010; 2022) e o HistCite de Garfield (2009). No que respeita a resultados, realçamos a emergência de estudos assinados pelos próprios profissionais em revistas ligadas às suas áreas, o que parece apontar no sentido das dimensões relacionadas com o autocuidado serem parte integrante do exercício profissional. Em termos de temáticas emergentes, as relacionadas com o COVID-19 surgem, assim como palavras-chave relacionadas com a saúde mental e a resiliência. Temas mais centrados em performance laboral têm tempo médio de publicação mais antigo. Registamos também que palavras-chave relacionadas com as novas tecnologias são praticamente ausentes na nossa pesquisa o que poderá indicar uma área de investigação ainda a explorar.

Resumo Objetivou-se avaliar os impactos da COVID-19 no rastreamento do câncer de mama no Brasil. Coletaram-se dados do Sistema de Informações Ambulatoriais referentes a “mamografia bilateral para rastreamento” de janeiro/2015 a dezembro/2021. As análises foram feitas por região e para o Brasil. Calculou-se a média de exames em cada mês do ano com base nos dados de 2015 a 2019, a qual foi comparada, mensalmente, com o quantitativo de exames em 2020 e 2021, obtendo-se a diferença bruta e percentual entre esses valores. A mesma análise foi realizada para o número total de exames em 2020 e 2021, individualmente, e para os dois anos em conjunto. Em 2020 houve quedas no número de exames que variaram de 25% (Norte) a 48% (Nordeste), culminando em 1,749 milhão de exames a menos no país (queda de 44%). Em 2021, a região Centro-Oeste apresentou quantitativo de exames 11% superior ao esperado, enquanto as demais regiões apresentaram quedas entre 17% (Norte) e 27% (Sudeste/Sul), culminando em negativo de 927 mil exames no país (redução de 23%). Na análise conjunta (2020/2021), encontraram-se reduções que variaram de 11% (Centro-Oeste) a 35% (Sudeste/Sul), culminando em negativo de 2,676 milhões de procedimentos no Brasil (queda de 33%).

Abstract The scope of this study was to evaluate the impacts of COVID-19 on breast cancer screening in Brazil. Data were collected from the Ambulatory Information System relating to “bilateral screening mammography” from January/2015 to December/2021. Analyses were performed by region and for Brazil. The average of exams in each month of the year was calculated based on 2015-2019 data, which was compared, monthly, with the number of exams in 2020 and 2021, obtaining the gross and percentage difference between these values. The same analysis was performed for the total number of exams in 2020 and 2021, individually, and for the two years combined. In 2020 there were reductions in the number of exams, which ranged from 25% (North) to 48% (Northeast), resulting in 1.749 million fewer exams than expected in the country (a drop of 44%). In 2021, the Midwest region presented a number of exams 11% higher than expected, while the other regions presented drops between 17% (North) and 27% (Southeast/South), resulting in 927 thousand exams fewer than expected in Brazil (reduction of 23%). In the joint analysis (2020/2021), reductions varied by region from 11% (Midwest) to 35% (Southeast/South), culminating in 2.676 million exams fewer than expected in Brazil (reduction of 33%).

ABSTRACT: Increasingly, fast-growing forest plantations are able to support the wood supply but may simultaneously reduce water availability. The trade-off between wood production and water supply is more evident in areas with low water availability, high seasonal variation, or high water demand from local communities. The management regime adopted in forest plantations can either increase or reduce this trade-off. Thus, we assess herein the water and wood supply under different fast-growing forest plantation management regimes to understand how forest management practices can balance the provision of these services. The study was conducted at two catchments with a predominance of fast-growing forest plantations, namely, the mosaic management catchment (MMC) and the intensive management catchment (IMC). Rainfall and streamflow were monitored for three water years. Hydrological indexes were calculated to assess the hydrological regime of both catchments, and make inventories of the forest to assess forest growth rates. MMC had streamflow coefficients, baseflow index and baseflow stability higher than those of IMC. Mean annual wood increment was 32.73 m3 ha-1 yr-1 in MMC, with a mean age of 15 years, and 44.40 m3 ha-1 yr-1 in IMC at coppice in the second year. MMC hydrological indexes remained stable over the period studied, while in IMC the hydrological indexes were affected by climatic variations, mainly in drier years. MMC showed potential for supplying both water and wood. However, in IMC there was a trade-off between wood supply at the expense of the water supply. Thus, the intensity of fast-growing management can be adjusted to achieve a balance between water and wood supply on a catchment scale.

Abstract Objective: To develop a rapid review on effective actions for the promotion of breastfeeding and healthy complementary feeding in primary health care and to summarize a list of actions and their elements for implementation. Data source: The review included systematic reviews on the effectiveness of interventions to promote breastfeeding and/or healthy complementary feeding for mothers and other caregivers, and/or professionals who work with this population, in comparison with any usual approach or none. Data synthesis: A total of 32 systematic reviews were included in the evidence synthesis. Ten types of interventions were evaluated in systematic reviews on promotion of breastfeeding and four types of interventions on promotion of healthy complementary feeding. The synthesis allowed six aspects to be discussed, and these must be considered to increase the chances of interventions’ impact: type of intervention, target audience, timing of intervention, actors that can implement it, strategies and methods of intervention, and intensity of intervention. Conclusions: It was possible to assemble a list of actions whose effectiveness has already been demonstrated, providing elements for local adaptations. Evidence is expected to support and strengthen the implementation of programs aimed at promoting breastfeeding and complementary feeding in primary health care.

Abstract Pitaya is a rich source of bioactive compounds, such as polyphenols and betalains. Moreover, these compounds has been associated with reduced risk of type 2 diabetes mellitus. The aim of this study is to evaluate the effect of this fruit on glycemia and oxidative stress in aloxan-induced diabetic mice. Thus, considering that In the in vivo assays, the mice were divided into 5 groups (n = 6): (a) healthy group treated with water; (b) diabetic mice treated with metformin at 200 mg/kg body weight diluted in water; (c) untreated diabetic mice; (d) diabetic mice treated with pitaya at 200 mg/kg and (e) diabetic mice treated with pitaya at 400 mg/kg of body weight diluted in water. The results shows that pitaya was able significantly to reduce blood glucose (p < 0.05) (200 mg/kg); significantly reduce cholesterol (200 and 400 mg/kg) and significantly increase HDL-c (400 mg/kg) levels. In the oxidative stress experiment, Malondialdehyde levels in the liver were significantly reduced (p < 0.05) in the groups treated with pitaya, when compared to the other groups, suggesting lower lipid peroxidation. The consumption of pitaya reduced the blood glucose and cholesterol and increase the HDL, in addition, the lipid peroxidation - which is common in diabetic patients, was reduced.

ABSTRACT To evaluate the effect of different iron dextran application programs on the performance, fecal score, and skin color of suckling piglets, as well as sow performance, 288 piglets from 24 sows were allocated to four treatments in six replications with 12 piglets per experimental unit, in a block design. The treatments were as follows: T200_000, T200_100, T200_200, and T100_100, whose respective values (in mg) corresponded to the applications of the first dose of iron dextran on the second day of life and of the second dose on the 10th day. Piglets on T200_000 and T200_200 showed the highest feed intake. In the period from 10 to 22 days, piglets receiving T100_100 exhibited the highest fecal score. On the 10th day of age, the lowest lightness (L*) value on the ear was obtained with T200_100, and the highest with T100_100. Treatments T200_000, T200_100, and T200_200 generated the highest red color (a*) intensity on the ear, whereas T100_100 provided the lowest hue and parameter b* values on the leg and snout. On the 22nd day of age, the highest b* and hue values of the ear and snout were found in the group fed T100_100. In conclusion, all evaluated programs were efficient in preventing iron deficiency anemia in newborn piglets. To reduce expenses, we recommend administering a single dose of 200 mg of iron dextran to piglets on the second day of life.

RESUMO Foram utilizados 288 leitões de 24 matrizes, distribuídos em delineamento em blocos com quatro tratamentos, seis repetições, com 12 leitões por unidade experimental com objetivo de avaliar diferentes programas de aplicação de ferro dextrano sobre desempenho, escore fecal e coloração de pele de leitões em aleitamento, assim como as repercussões sobre o desempenho das matrizes. Os tratamentos consistiram em: T200_000; T200_100; T200_200; e T100_100; nos quais os valores corresponderam, respectivamente (em mg), à aplicação da primeira dose de ferro dextrano no segundo dia de vida e à aplicação da segunda dose no 10º dia. Os leitões que foram submetidos a T200_000 e a T200_200 tiveram maior consumo de ração. No período de 10 a 22 dias, os leitões de T100_100 obtiveram maior escore fecal. Ao 10º dia de idade dos leitões, o menor valor de luminosidade (L*) da orelha foi em T200_100 e o maior valor em T100_100. A maior intensidade da cor vermelha (a*) na orelha foi obtida em T200_000, T200_100 e T200_200. Na tonalidade e no parâmetro b* do pernil e do focinho, T100_100 foi aquele que apresentou menor valor. No 22º dia de idade dos leitões, o maior valor de b* e da tonalidade da orelha e do focinho foi verificado em T100_100. Conclui-se que todos os programas avaliados foram eficientes na prevenção da anemia ferropriva em leitões neonatos. Visando a redução de gastos, recomenda-se a administração de uma única dose de 200 mg de ferro dextrano no segundo dia de vida dos leitões.

ABSTRACT Peanut cultivation in the northeast of Brazil has been badly affected by salts accumulating in the irrigation water; in this respect, the use of plant mulch is one way of mitigating salt stress. The aim of this study was to evaluate the effect of irrigation using brackish water under different mulching strategies on productivity and water use efficiency in the peanut. The experiment was carried out under field conditions in Redenção, in the state of Ceará, in a randomised block design of split-plots with five replications, in which the plots corresponded to two levels of electrical conductivity of the irrigation water (0.8 and 4.0 dS m-1), and the subplots to six mulching strategies based on the phenology of the crop (MS1: mulch throughout the cycle; MS2: flowering stage; MS3: appearance of the gynophore; MS4: pod formation; MS5: final flowering stage; MS6: no mulch). The following were determined at the end of the experimental cycle: commercial, non-commercial and total number of pods, number of grains per pod, pod length and diameter, productivity and water use efficiency. Irrigation with lower-salinity water, together with mulching during the phenological stages of the peanut, affords better productive performance and greater water use efficiency. Salt stress reduced the length and diameter of the pods and had a negative effect on productivity and water use efficiency, both with and without the use of plant mulch during the phenological stages.

ABSTRACT Objective To translate and cross-culturally adapt the Noise Exposure Questionnaire (NEQ) and 1-Minute Noise Screen (NEQ-S) instruments to Brazilian Portuguese. Methods Procedures widely known in health research were used in the translation and cross-cultural adaptation process, comprising the following steps: initial translation, synthesis of translations, back-translation, expert committee, pretest, and content and layout validation. Altogether, 60 workers participated in the pretest by answering the questionnaires and then evaluating them in terms of understandability, layout, clarity, and writing. Reliability was verified with Cohen's kappa test, and the internal consistency was analyzed with Cronbach’s alpha coefficient. Results The translated and adapted versions of NEQ and NEQ-S were similar in terms of general and referential meanings. However, some modifications and adaptations were made to adapt them to the Brazilian reality. The kappa test indicated moderate agreement and Cronbach’s alpha coefficient, substantial internal consistency. Conclusion The translation and cross-cultural adaptation were carried out according to the methodology recommended in the national and international literature, performing the necessary equivalences to maintain the face and content validity with the original instrument. The availability of NEQ and NEQ-S in Brazilian Portuguese opens new fields of research to quantify yearly noise exposure more in-depth.

RESUMO Objetivo Traduzir e realizar a adaptação transcultural dos instrumentos Noise Exposure Questionnaire (NEQ) e 1-Minute Noise Screen (NEQ-S) para a versão em português brasileiro. Método O processo de tradução e adaptação transcultural seguiu procedimentos amplamente utilizados em pesquisas da área da saúde, compostos pelas seguintes etapas: tradução inicial, síntese das traduções, retrotradução, comitê de especialistas, pré-teste, e validação do conteúdo e aparência. Na etapa de pré-teste, participaram 60 trabalhadores, que responderam aos questionários e, posteriormente, os avaliaram quanto ao: entendimento, aparência, clareza e escrita. Para a verificação da confiabilidade, foi utilizado o teste kappa de Cohen e para a análise da consistência interna foi aplicado o coeficiente alfa de Cronbach. Resultados As versões traduzidas e adaptadas dos questionários NEQ e NEQ-S mostraram-se semelhantes em relação ao significado geral e referencial. Entretanto, algumas modificações e adaptações foram realizadas, para adequação à realidade brasileira. O teste kappa indicou concordância moderada e o coeficiente alfa de Cronbach, consistência interna substancial. Conclusão A tradução e a adaptação transcultural foram realizadas de acordo com a metodologia preconizada na literatura nacional e internacional, incluindo-se as equivalências necessárias para a manutenção da validade de face e conteúdo com o instrumento original. A disponibilização dos questionários NEQ e NEQ-S na versão da língua portuguesa brasileira abre novos campos de pesquisa para aprofundamento da quantificação de exposição anual ao ruído.

BACKGROUND Trypanosoma cruzi, which causes Chagas disease (CD), is a versatile haemoparasite that uses several strategies to evade the host’s immune response, including adipose tissue (AT), used as a reservoir of infection. As it is an effective barrier to parasite evasion, the effectiveness of the drug recommended for treating CD, Benznidazole (BZ), may be questionable. OBJECTIVE To this end, we evaluated the parasite load and immunomodulation caused by BZ treatment in the culture of adipocytes differentiated from human adipose tissue-derived stem cells (ADSC) infected with T. cruzi. METHODS The ADSC were subjected to adipogenic differentiation. We then carried out four cultures in which we infected the differentiated AT with trypomastigote forms of the Y strain of T. cruzi and treated them with BZ. After the incubation, the infected AT was subjected to quantitative polymerase chain reaction (qPCR) to quantify the parasite load and transmission electron microscopy (TEM) to verify the infection. The supernatant was collected to measure cytokines, chemokines, and adipokines. FINDINGS We found elevated secretion of IL-6, CXCL-10/IP-10, CCL2/MCP-1, CCL5/RANTES, and leptin in infected fat cells. However, treatment with BZ promoted a decrease in IL-6. MAIN CONCLUSION Therefore, we believe that BZ has a beneficial role as it reduces inflammation in infected fat cells.
