Abstract BACKGROUND: The Hip Sports Activity Scale (HSAS) is a reliable and valid tool for determining the levels of sports activities among patients with femoroacetabular impingement (FAI). OBJECTIVE: To translate and cross-culturally adapt the HSAS to the Brazilian Portuguese language. DESIGN AND SETTING: This was a cross-sectional study conducted at the State University of Rio de Janeiro. METHODS: The Brazilian version of the HSAS was developed following a process that comprised six steps: translation, synthesis, back-translation, review by committee, pretesting and submission of documentation to the developers. The translation phase involved three independent bilingual translators whose mother language was Brazilian Portuguese. The back-translation phase involved three independent translators whose mother language was English. In order to verify comprehension of the questionnaire, 30 undergraduate students in physical education (65% men), with mean age 23.2 years (standard deviation = 6.8), participated in the pre-testing phase. RESULTS: During the translation step, some terms and expressions were changed to obtain cultural equivalence to the original HSAS. In the pre-testing phase, each item of the scale showed a comprehension level of 100%. CONCLUSION: The HSAS was translated from English to the Brazilian Portuguese language and adapted to Brazilian culture. The HSAS validation is ongoing.

Abstract BACKGROUND: Gastrointestinal (GI) symptoms are frequent complaints from individuals with nonalcoholic fatty liver disease (NAFLD). Dyspepsia is a universal clinical symptom and is among the most common GI complaints observed in the general population, but its prevalence in the population with NAFLD has not been previously investigated. OBJECTIVE: To compare the prevalence of functional dyspepsia (FD) between patients with NAFLD and controls without liver disease. DESIGN AND SETTING: Cross-sectional study at the Outpatient Liver Clinic, University Hospital, Belo Horizonte, Brazil. METHODS: We included 96 NAFLD patients and 105 controls without liver disease. All participants were assessed for GI symptoms in accordance with the Rome III criteria. Evaluation methods included a questionnaire for FD (validated in Brazil), laboratory tests and upper GI endoscopy. RESULTS: Mean age and sex were similar between the groups. The NAFLD group presented higher frequency of proton-pump inhibitor usage (31.3% vs 4.8%; P < 0.001) and prevalence of FD (25.0% versus 12.4%; P = 0.021). The symptom frequencies were as follows: postprandial distress, 22.9% versus 11.4% (P = 0.030); postprandial fullness, 18.8% versus 10.5% (P = 0.095); early satiation, 8.3% versus 5.7% (P = 0.466); and epigastric pain or burning, 18.8% versus 5.7% (P = 0.004), in NAFLD patients and controls, respectively. Multivariate analysis demonstrated that female sex (odds ratio, OR 6.97; 95% confidence interval, CI: 1.51-32.12; P = 0.013) and NAFLD diagnosis (OR 2.45; 95% CI: 1.14-5.27; P = 0.021) were independently associated with FD occurrence. CONCLUSION: FD occurs more frequently in individuals with NAFLD than in controls without hepatic disease.

RESUMO Antecedentes: As ataxias espinocerebelares (SCA) são um grupo de doenças neurodegenerativas caracterizadas pela deterioração do equilíbrio e da funcionalidade, que tende a acompanhar a progressão da doença. Não existe uma ligação estabelecida entre os marcadores clínicos formais de gravidade e escores funcionais e de equilíbrio que possam orientar as equipes de reabilitação. Objetivo: Avaliar a relação entre escalas funcionais e de gravidade da ataxia, buscando identificar pontos de corte para a perda funcional relacionados aos escores de gravidade e aos patamares de Risco de Quedas. Métodos: Uma amostra consecutiva de 89 pacientes com diagnóstico molecular de SCA (31-SCA2 e 58-SCA3) foram avaliados para funcionalidade MIF-AVDs (Medida de independência funcional-Atividades da vida diária) e Lawton-AIVDs (Atividades instrumentais da vida diária), equilíbrio (EEB-escala de Equilíbrio de Berg), e gravidade da ataxia (SARA-escala para avaliação e graduação de ataxia). Resultados: Os principais pontos de corte de deficiência foram: com 12 pontos no SARA começa a necessidade de supervisão para MIF-AVDs e com 14 pontos no SARA começa a necessidade de supervisão para Lawton-AIVDs. Os primeiros itens a necessitar de assistência foram “expressão” e “compras”, respectivamente. Com 20 pontos no SARA os pacientes eram dependentes em todos os itens MIF/LAWTON. O item com maior impacto na discriminação entre dependentes e independentes foi “meio de transporte” na Lawton e o domínio “locomoção” na MIF. O escore médio no SARA foi de 9,9 pontos para pacientes classificados com baixo risco na EEB, 17,4 para médio risco e 25,2 para alto risco. Conclusões: A análise da correlação entre a gravidade da ataxia e as escalas funcionais pode ser um importante guia no entendimento da progressão da dependência funcional em indivíduos com SCA.

ABSTRACT Background: Spinocerebellar ataxias (SCAs) are a group of neurodegenerative diseases characterized by deterioration of balance and functionality that tends to follow disease progression. There is no established link between formal clinical markers for severity and functional/balance scores that could guide rehabilitation teams. Objective: To evaluate the relationship between functional scales and ataxia severity in order to identify cutoff landmarks for functional loss and estimate the mean SARA (Scale for Assessment and Rating of Ataxia) score for the risk ratings for falls on the BBS (Berg Balance Scale). Methods: Consecutive patients with a molecular diagnosis of SCA (total 89: 31 with SCA2 and 58 with SCA3) were assessed for functionality FIM-ADL (Functional Independence Measure-activities of daily living and Lawton-IADL (instrumental activities of daily living), balance (BBS) and disease severity (SARA). Results: The main disability cutoff landmarks were that the need for supervision for FIM-ADL starts with 12 points on SARA and the need for supervision for Lawton-IADL starts with 14 points on SARA. The first items to require assistance were “expression” and “shopping”, respectively. At 20 points on SARA, patients were dependent on all FIM and Lawton items. The item with the greatest impact on distinguishing dependents from independents was “means of transport” in Lawton-IADL and the domain “locomotion” in FIM-ADL. The mean SARA score for patients classified as low risk in the BBS was 9.9 points, and it was 17.4 for medium risk and 25.2 for high risk. Conclusions: Analysis on the correlation between the severity of ataxia and functional scales can form an important guide for understanding the progression of functional dependence among individuals with SCAs.

ABSTRACT Objective: To assess the incidence of neuropsychomotor developmental delay at 6 and 12 months of corrected gestational age in children born at 32 gestational weeks or less. Methods: A descriptive and prospective study was carried out at two public maternity hospitals. Between April 2017 and January 2019, we assessed 133 children without any known risk factors for neuropsychomotor developmental delay. The Bayley III scale was used to evaluate cognitive and motor development. The p value of the numerical variables was calculated using the Mann-Whitney test, whereas proportions of categorical variables were compared using the Z-test. Results: The mean maternal age was 26±6.9 years,78.8% were from middle and lower economic classes, and 57.1% of the analyzed children were female. Children presented with a higher incidence of delay at 12 months than at 6 months (10.3 and 2.3% at 12 and 6 months, respectively, for the cognitive score; 22.7 and 12% at 12 and 6 months, respectively, for the composite motor score; and 24.7 and 8.4% at 12 and 6 months, respectively, for the fine motor score). Conclusions: Cognitive and motor developmental delays were significant, with the highest incidence at 12 months. The results of this study encourage further research on this topic, since the exclusion criteria were comprehensive and the delays in neuropsychomotor development were significant.

RESUMO Objetivo: Conhecer a incidência de atraso de desenvolvimento neuropsicomotor de crianças nascidas com idade gestacional menor ou igual a 32 semanas aos 6 e 12 meses de idade gestacional corrigida. Métodos: Estudo descritivo e prospectivo realizado em duas maternidades públicas. Foram incluídas 133 crianças no período de abril de 2017 a janeiro de 2019 sem fatores conhecidos para atraso no desenvolvimento neuropsicomotor. Para avaliação do desenvolvimento cognitivo e motor, utilizou-se a escala Bayley III. Para calcular o valor p das variáveis numéricas, foi usado o teste de Mann-Whitney, e para as categóricas, o teste Z de comparação de proporções. Resultados: A média da idade materna foi de 26±6,9 anos, a classificação econômica prevalente foi classe média e baixa, com percentual de 78,8%, e os recém-nascidos do sexo feminino representaram 57,1% das crianças. As crianças apresentaram maior incidência de atraso aos 12 meses, sendo 10,3% aos 12 meses e 2,3% aos 6 meses para o escore cognitivo, 22,7 e 12% aos 12 e 6 meses, respectivamente, no escore motor composto e 24,7% aos 12 meses e 8,4% aos 6 meses no escore motor fino. Conclusões: Atraso nos desenvolvimentos cognitivo e motor foi significativo, com maior incidência aos 12 meses. O escore motor composto apresentou a maior incidência de atraso de desenvolvimento. Os resultados do estudo são instigantes, uma vez que os critérios de exclusão foram abrangentes, e os atrasos no desenvolvimento neuropsicomotor, significativos.

This essay explores the tattoos and scars that convey narratives on experiencing and living with chronic, rare, and complex illnesses. We view such marks as public expressions, when individuals bear witness to lives traversed by disability and frailty, whether as their own personal experience or in the role of caregivers. The body as witness and performative support is explored here in its aesthetic and political dimensions, in the expression of symbolic contents that gain visibility in the affirmation of neglected identities and agendas by persons who claim the recognition and valorization of their lives.

Este ensaio explora as tatuagens e cicatrizes que se articulam às narrativas sobre viver e conviver com as condições de adoecimento crônico, raro e complexo. Entendemos essas marcas como expressões públicas de um testemunho daqueles afetados pela deficiência e fragilidade da vida, seja como experiência pessoal ou no papel de cuidadores. O corpo como testemunho e suporte performático é explorado na sua dimensão estética e política, na expressão de conteúdos simbólicos que ganham visibilidade na afirmação de identidades e pautas negligenciadas de um público que reivindica reconhecimento e valorização de suas vidas.

Abstract Objective To characterize the national and international scientific production on errors in health work from 2000 to 2020. Methods This is an integrative literature review of national and international studies, carried out in the MEDLINE, LILACS/BIREME, PubMed and SciELO databases. A total of 4164 studies were found, 148 of which were included and submitted to thematic content analysis. The searches were carried out from January to March 2020 and April 2021. The results were systematized into three thematic categories. Results In the category Characteristics of studies on errors, it was evidenced that the most frequent professional categories in error occurrence are nurses, physicians and pharmacists; regarding Characteristics of error in health work, the most reported types are medication, diagnosis and nursing care errors, including patient falls., phlebitis resulting from peripheral venous catheters, occurrence of pressure ulcers and extubation of drains, catheters and probes; and in Context for error occurrence, individual elements and work context were identified, highlighting the latter. Conclusion It was evident that error in health work occurs in a context of precarious work, with work processes marked by heterogeneity. From the understanding that health workers make mistakes and that the precariousness of work enhances error occurrence, it is necessary to reorganize health systems so that the opportunities for errors to occur are reduced and that learning is promoted when they occur.

Se realizaron entrevistas semiestructuradas con padres y otros parientes. Reflejamos en la investigación el significado de tener un bebé con marcas corporales inesperadas, sufrimiento moral, razón de la discapacidad social y carga de cuidado, así como la necesidad de redes de apoyo. Concluimos que las políticas públicas, especialmente las políticas sociales (salud, educación, y asistencia social), son cruciales produciendo mecanismos compensatorios, reconocimiento e inclusión social de estos niños y sus familias.

This article uses a socio-anthropological framework to explore the stigmas around interactions with children born with congenital Zika syndrome caused by the Zika virus epidemic in two Brazilian municipalities. Semi-structured interviews were conducted with parents and other relatives. We reflected on the search for meaning when having a baby with unexpected body marks, the moral suffering, the societal ableism, the burden of care, and the need for support networks. We concluded that public policies, especially social policies (health, education, and social assistance), are essential for compensatory mechanisms, recognition, and social inclusion of these children and their families.

Abstract: The osteolytic activity of odontogenic cysts and tumors is directly associated with their growth and aggressiveness. The influence of proteins expressed by epithelial and mesenchymal cells on this biological event differs between indolent cystic lesions, aggressive cystic lesions, and odontogenic tumors. The objective of this study was to compare the immunohistochemical expression of factors that stimulate (receptor activator of nuclear factor kappa-Β ligand – RANKL, cathepsin K – CatK and matrix metallopeptidase 8 – MMP-8) and inhibit (osteoprotegerin – OPG) osteoclastogenesis between dentigerous cyst (DC), glandular odontogenic cyst (GOC), odontogenic keratocyst (OKC), and ameloblastoma (AB). Paraffin-embedded sections of nine DCs, nine GOCs, 20 OKCs, 21 ABs, and four dental follicles (DFs) were subjected to immunohistochemistry. Immunoreactivity was analyzed semiquantitatively and quantitatively in epithelium and connective tissue, respectively. The proteins were immunoexpressed in epithelial and mesenchymal cells of all lesions studied. The expression of RANKL and CatK was higher in OKC, AB, and GOC (p<0.005). Higher expression of OPG was found in DF and DC compared to the other markers (p<0.005). MMP-8 expression was high in GOC and OKC. This study demonstrated the differential expression of factors that inhibit and stimulate bone resorption during the development of DC, GOC, OKC, and AB. Higher expression of RANKL and CatK was observed in more aggressive lesions. OPG appears to be one of the molecules responsible for the slower growth of DC.

BACKGROUND Leishmania parasites cause leishmaniasis that range from self-limiting cutaneous lesions to more serious forms of the disease. The search for potential drug targets focusing on biochemical and metabolic pathways revealed the sterol biosynthesis inhibitors (SBIs) as a promising approach. In this class of inhibitors is found ketoconazole, a classical inhibitor of 14α-methysterol 14-demethylase. OBJECTIVE The present study aimed to better understand the biological response of Leishmania (Leishmania) amazonensis promastigotes at the cellular level after ketoconazole treatment. METHODS Herein, techniques, such as fluorimetry, flow cytometry, fluorescence microscopy, electron and scanning microscopy were used to investigate the cellular structures and to identify organelles affected by ketoconazole treatment. FINDINGS The study demonstrated, for the first time, the effect of ketoconazole on mitochondrion functioning and its probable relationship to cell cycle and death on L. (L.) amazonensis promastigotes (IFLA/BR/67/PH8 strain). MAIN CONCLUSIONS Ketoconazole-induced mitochondrial damages led to hyperpolarisation of this single organelle and autophagic vacuoles formation, as a parasite survival strategy. These damages did not reflect directly on the parasite cell cycle, but drove the parasites to death, making them susceptible to ketoconazole treatment in in vitro models.

Abstract Tectonic rejuvenation has been widely described in ancient rifting areas of intraplate settings, despite extensive active tectonics being discontinued long ago. Various models have been invoked to justify such tectonic rejuvenation, suggesting that the long-term deformation in intraplate interiors may be more complex than once supposed. Inherited weakness zones, e.g., pre-existing faults are stress concentrators. However, not all weakness zones in plate interiors show tectonic rejuvenation and recognizing intraplate fault reactivation remains puzzling. Bedrock channels play an essential role in tectonically unstable landscapes and therefore they may unveil which pre-existing structures have been rejuvenated. Here we explore the Cinzas Catchment in order to investigate the interactions between tectonic rejuvenation, bedrock inheritance and geomorphic river signatures in an important Brazilian rifting feature, the Ponta Grossa Arch. We perform a geomorphic analysis combined with fieldwork, dating techniques and existing data to evaluate whether the geomorphic responses of the major rivers show perturbations related to the bedrock inheritance and post-rift rejuvenation. We also show that the interactions between river signatures and the bedrock fault zones are responses to post-rifting rejuvenation coupled with bedrock inheritance. This post-rifting rejuvenation is consistent with a mosaic of superimposed mechanisms which have been invoked by previous studies.
