Association between obesity and thyroid cancer in women: a comparative study of malignant and benign nodules
Introduction: Obesity is a disease that induces various changes in the body, including oxidative stress, which can contribute to the development of cancer cells in the thyroid. Objective: Evaluate whether the presence of obesity and antioxidant defense is associated with the diagnosis of malignant thyroid nodules in adult women. Methods: The cross-sectional study consisted of 109 females diagnosed with nodular thyroid disease who underwent thyroidectomy surgery, with benignity or malignancy classification previously defined by Fine Needle Aspiration Biopsy (FNAB) and the Bethesda system. The participants had anthropometric and clinical markers assessed before the surgical process. The prevalence ratio of malignant nodules with obesity and antioxidant markers was determined using Poisson regression analysis. Results: After biopsy analysis, 70 women were diagnosed with a benign nodule and 39 with a malignant nodule. A significant association was found between body mass index and nodule type (p<0.015). All but one participant had glutathione peroxidase and superoxide dismutase enzyme activity above the reference values. The prevalence of malignant nodules was significantly higher in women diagnosed with obesity (PR=1.94; 95% CI: 1.01 - 3.17; p=0.046) compared to those without obesity. Antioxidant markers showed no association with nodule malignancy. Conclusion: The prevalence of malignant thyroid nodules in adult women is higher in those who are obese, and the presence of thyroid nodules, regardless of their type, can influence the increase in antioxidant enzyme activity.

CAPACITAÇÃO EM BOAS PRÁTICAS E VIGILÂNCIA SANITÁRIA
Relatar a experiência de profissionais da Vigilância Sanitária na capacitação prévia de boas práticas de manipulação de alimentos aos profissionais que trabalharam em uma festa cultural de um município da região do Cariri, Ceará. Estudo transversal de natureza qualitativa, descritivo no formato de relato de experiência. Todos os participantes receberam informações sobre boas práticas de manipulação de alimentos baseadas na legislação vigente, conforme as características do serviço de alimentação e de cada público-alvo no contexto de um evento de massa, de maneira simples, participativa e didática. As capacitações são mecanismos que podem ser utilizados nas ações educativas pactuadas pela VISA de maneira contínua, seja para o setor regulado, seja para a população, com a finalidade de promover e evitar agravos à saúde do indivíduo e da coletividade.

CONDIÇÕES HIGIÊNICO-SANITÁRIAS DE RESTAURANTES VIRTUAIS
Durante a pandemia de COVID-19 o Poder Executivo editou decretos com medidas preventivas a serem cumpridas por pessoas físicas e jurídicas no combate à COVID-19. Neste contexto, as academias tiveram prioridade de reabertura após o isolamento social rígido ao serem consideradas atividades essenciais. O objetivo deste trabalho foi avaliar o cumprimento das medidas de prevenção à COVID-19 relacionadas ao protocolo sanitário setorial nas academias de Fortaleza. Trata-se de um estudo descritivo, quantitativo e documental que avaliou demandas de fiscalização do sistema da Agência de Fiscalização de Fortaleza, executadas em academias, de 25/07/2020 a 14/01/2022. As academias (68,71%) que estavam adequadas ao protocolo setorial foram consideradas espaços seguros. As que apresentavam não conformidade foram verificadas em 16,67% das demandas. Como fator limitante do estudo destacam-se os despachos fiscais (14,62%) que não mencionaram a verificação do protocolo.

Selenium and thyroid cancer: a systematic review
The aim of the study was to investigate the association between blood and tissue levels of selenium and thyroid cancer through a systematic review. We searched for observational studies written in English, Spanish, and Portuguese indexed in PubMed, LILACS, and Scielo without date restriction, that evaluated the association between selenium levels in whole-blood, serum, or plasma and/or thyroid tissue and thyroid cancer, both in individuals with cancer of thyroid as in healthy individuals. Then data were extracted and analyzed. Of the 570 articles identified, five cross-sectional studies were included in the review. In one study, lower concentrations of selenium were found in whole-blood (0.543 μg/ml) and in the thyroid (0.88 μg/g) of thyroid cancer patients compared to controls. Another study showed a decrease in serum selenium concentrations in patients with follicular carcinoma and papillary types (0.077 ± 0.021 μg/ml and 0.080 ± 0.020 μg/ml, respectively). On the other hand, other studies showed no difference in plasma selenium content or glutathione peroxidase activity among patients and healthy volunteers. The available evidence on this issue is inconclusive. Additional studies are needed to elucidate the association between serum and/or tissue levels of selenium and the development of thyroid cancer.

Inadequação do consumo alimentar de nutrientes antioxidantes em nefropatas crônicos em hemodiálise
INTRODUÇÃO: o consumo de nutrientes antioxidantes por pacientes em hemodiálise é importante, pois a doença renal pode desencadear desequilíbrio oxidativo decorrente da intensa produção de espécies reativas, falhas nos sistemas antioxidantes e retenção do soluto oxidado. OBJETIVO: avaliar a adequação do consumo alimentar de nutrientes antioxidantes por pacientes renais crônicos em hemodiálise. MÉTODOS: o estudo foi desenvolvido com pacientes em tratamento de hemodiálise, afiliados a duas clínicas especializadas em Fortaleza, Ceará, Brasil. Os dados foram coletados por meio de três recordatórios de 24h e tabulados no programa Excel 2007®. Foram realizadas análises qualitativa e quantitativa da ingestão de selênio, zinco, vitamina A, vitamina C e vitamina E. O estudo incluiu 26 homens e 18 mulheres entre 19 e 83 anos de idade. RESULTADOS: encontraram-se médias de ingestão abaixo da EAR (Estimated Average Requeriment) de zinco, vitamina A, C e E e prevalências de risco de inadequação superior a 50% para todos os micronutrientes analisados, exceto o selênio. A ingestão de vitamina E foi inferior a EAR em 100% dos pacientes. CONCLUSÃO: os pacientes renais crônicos em hemodiálise se encontravam com ingestão inadequada de micronutrientes antioxidantes, contribuindo para o aumento do estresse oxidativo.

Effect of progesterone on the expression of GABAA receptor subunits in the prefrontal cortex of rats: implications of sex differences and brain hemisphere
Progesterone is a neuroactive hormone with non‐genomic effects on GABAA receptors (GABAAR). Changes in the expression of GABAAR subunits are related to depressive‐like behaviors in rats. Moreover, sex differences and depressive behaviors have been associated with prefrontal brain asymmetry in rodents and humans. Thus, our objective was to investigate the effect of progesterone on the GABAAR α1 and γ2 subunits mRNA expression in the right and left prefrontal cortex of diestrus female and male rats exposed to the forced swimming test (FST). Male and female rats (n = 8/group) were randomly selected to receive a daily dose of progesterone (0·4 mg·kg–1) or vehicle, during two complete female estrous cycles (8–10 days). On the experiment day, male rats or diestrus female rats were euthanized 30 min after the FST. Our results showed that progesterone significantly increased the α1 subunit mRNA in both hemispheres of male and female rats. Moreover, there was an inverse correlation between depressive‐like behaviors and GABAAR α1 subunit mRNA expression in the right hemisphere in female rats. Progesterone decreased the GABAAR γ2 mRNA expression only in the left hemisphere of male rats. Therefore, we conclude that the GABAA system displays an asymmetric distribution according to sex and that progesterone, at lower doses, presents an antidepressant effect after increasing the GABAAR α1 subunit expression in the right prefrontal cortex of female rats.
