ABSTRACT Objective: Percutaneous ethanol injection (PEI) is an alternative to surgery for the treatment of thyroid nodules (TNs). However, size reductions of treated (TTNs) and untreated TN (UTNs) have not been compared. Volumetric reductions in TTNs with PEI were evaluated by comparing TTNs and UTNs in the same patient, and independent variables predicting good post-PEI outcomes were analyzed. Materials and methods: Overall, 282 patients with multinodular goiters were selected. Two nodules located in different lobes were compared for common disease behaviors. Overall, 150 nodules were selected from 75 patients (6 M: 69 F) with a mean age of 50.1 ± 17.4 years. This prospective nonrandomized intervention study prioritized treating TNs of greater volume or single hyperfunctioning TNs. A single observer experienced in PEI and an ultrasound specialist performed the interventions. Results and discussion: TTNs (mean volume: 14.8 ± 16.2 mL) were reduced by 72.6 ± 27.3% of their initial volume, while UTNs increased by a mean of 365.7 ± 1.403.8% (p < 0.00001). The patients underwent a mean of 4.0 ± 3.1 outpatient PEI sessions without relevant complications. Logistic regression analysis showed that the magnitude of the PEI induced reduction was associated with the number of treatment sessions (p = 0.03, CI [1.1-38.2]) and not with ultrasonographic characteristics of the nodules. Each PEI session increased the rate of TN reduction by a factor of 6.7. Conclusions: PEI is a well-tolerated outpatient procedure that effectively reduces the volume of TNs and is noticeably superior to conservative treatment for all ultrasonographic classifications.

Resumo Objetivo analisar as relações entre a esperança e o bem-estar psicológico de estudantes de enfermagem portugueses durante a crise pandêmica pela COVID-19. Método estudo descritivo-correlacional, com recurso a questionário online para coleta de dados. Participaram 705 estudantes de enfermagem com idade média de 21,74 anos (DP=4,44). Os instrumentos de coleta de dados utilizados foram a Escala de Esperança de Herth (HHI-PT) e a Escala de Medida de Manifestação de Bem-Estar Psicológico (EMMBEP). Foi utilizada a estatística descritiva e inferencial. Resultados na HHI-PT, o domínio afectivo-comportamental obteve a pontuação média mais alta, 3,30 (DP=0,45); no EMMBEP, foi o domínio sociabilidade, 3,64 (DP=0,77). Havia correlações moderadas a fortes (0,383 <r <0,917) entre o global e todos os domínios da esperança e bem-estar psicológico (≤0.001). Conclusão e implicações para a prática a esperança e o bem-estar psicológico dos estudantes de enfermagem durante a pandemia são variáveis correlacionados positivamente entre si. As medidas de promoção da saúde mental, a implementar pelas instituições de ensino, devem ter em consideração a associação entre essas duas variáveis.

Abstract Aim to analyze the relationship between hope and the psychological well-being of Portuguese nursing students during the COVID-19 pandemic crisis. Method this is a descriptive-correlational study using an online questionnaire for data collection. 705 nursing students participated, with a mean age of 21.74 years (SD=4.44). The data collection instruments used were the Herth Hope Index (HHI-PT) and the Well-Being Manifestations Measure Scale (WBMMS). Descriptive and inferential statistics were used. Results in the HHI-PT, the affective-behavioral domain had the highest mean score (3.30; SD=0.45), while in the WBMMS, it was the sociability domain, 3.64 (SD=0.77). There were moderate to strong correlations (0.383 <r <0.917) between the global and all domains of hope and psychological well-being (≤0.001). Conclusion and implications for practice nursing students’ hope and psychological well-being during the pandemic are variables that are positively correlated with each other. Strategies to promote mental health, to be implemented by educational institutions, must consider the association between these two variables.

Abstract Aim: To compare the masticatory performance associated with different rehabilitation strategies for patients with edentulous mandibles. Methods: one portion of the test food "Optocal" was provided to groups: Natural Dentition (n = 15), Mandibular Fixed Implant-Supported Prosthesis with Maxillary Fixed Prosthesis (n = 8), Mandibular Fixed Implant-Supported Prosthesis with Maxillary Removable Prosthesis (n = 14), Mandibular Implant-Retained Overdenture with Maxillary Removable Prosthesis (n = 16), and Complete Dentures (n = 16). The portion was collected after 40 chewing strokes, and then passed through a stack of eight sieves with decreasing apertures. Masticatory performance was determined by weighing the portion of food on each sieve. Results: the masticatory performance was: 71.00% for Natural Dentition, 41.57% for Mandibular Fixed Implant-Supported Prosthesis with Maxillary Fixed Prosthesis, 31.44% for Mandibular Fixed Implant-Supported Prosthesis with Maxillary Removable Prosthesis, 27.70% for Mandibular Implant-retained Overdenture, and 14.33% for Complete Dentures. The data were statistically compared using Student's t-test (p < 0.05). Natural Dentition and Complete Denture groups were statistically different from all other groups, with the Natural Dentition and Complete Denture groups exhibiting the highest and lowest masticatory performance values, respectively. Conclusions: Osseointegrated implants improved the masticatory performance of all implant-supported groups compared to the Complete Dentures group.

Este estudo focaliza as representações sociais de professores do ensino fundamental acerca da violência intrafamiliar. A amostra foi de 94 professores de escolas públicas e privadas (Distrito Federal e Goiás), graduandos em Pedagogia. Na coleta de dados, aplicou-se um questionário visando apreender as representações sobre violência intrafamiliar, nas dimensões informação, campo das representações sociais e atitudes dos sujeitos diante de casos comprovados ou suspeitos de alunos vitimados pela violência intrafamiliar. Os resultados apontam contradições e ambivalências entre os sentimentos e as atitudes dos professores em relação ao fenômeno. Indicam, ainda, que a representação social da violência intrafamiliar, para grande parte dos sujeitos, ainda passa pela consideração do poder da autoridade paterna/familiar, que dá direito aos pais de educar seus filhos como melhor lhes convier, indicando a necessidade da capacitação de professores, no âmbito da formação inicial e continuada, para lidar adequadamente com a problemática da violência intrafamiliar, no cotidiano escolar.

This study is focused on the social representations of elementary and middle school teachers about the inner-family violence. The used sample encompasses 94 teachers of public and private schools (Federal District and Goiás, Brazil), undergraduate students in Pedagogy. In the data collection process a questionnaire was applied in order to apprehend the representations about the inner-family violence in the dimensions of information, social representation field and attitudes, regarding proven and suspicious cases of students, victims of inner-family violence. The results point to contradictions and ambivalences between the teacher's feeling and attitudes in relation to the phenomenon. They also indicate that the social representation of inner-family violence for a great part of the individuals, still passes through the consideration of the authority power of parents and families, which gives them the right to educate their children as they deem most appropriate, indicating the necessity of training for teachers, in the initial and continuous education, to adequately deal with the inner-family violence problem in the school daily issues.
