Presumed acute posterior multifocal placoid pigmentary epitheliopathy associated with Bartonella infection / Epiteliopatia pigmentar placoide multifocal posterior aguda presumível associada com infecção por Bartonella

ABSTRACT To report a unique case of acute posterior multifocal placoid pigment epitheliopathy (APMPPE) in a patient with positive serology for Bartonella, presenting with ocular signs and symptoms not attributable to other diseases. A 27-year-old woman presented with decreased visual acuity in both eyes. Multimodal fundus image analysis was performed. A color fundus photograph of both eyes revealed peripapillary and macular yellow-white placoid lesions. The fundus autofluorescence of both eyes demonstrated hypo- and hyperautofluorescence of the macular lesions. Fluorescein angiography showed early-stage hypofluorescence and late staining of placoid lesions in both eyes. Spectral domain optical coherence tomography (SD-OCT) of both eyes revealed irregular elevations in the retinal pigment epithelium with the disruption of the ellipsoid zone on the topography of macular lesions. At 3 months after the treatment initiation for Bartonella infection, the placoid lesions became atrophic and hyperpigmented, and SD-OCT revealed loss of both the outer retinal layers and retinal pigment epithelium on the topography of macular lesions in both eyes.

RESUMO Caso de epiteliopatia pigmentada placoide multifocal posterior aguda presumida em paciente com sorologia positiva para Bartonella. Paciente feminina de 27 anos apresentou diminuição da acuidade visual em ambos os olhos. Análise multimodal de imagem foi realizada. A retinografia mostrou revelou lesões placoides amarelo-esbranquiçadas nas áreas peripapilar e macular de ambos os olhos. A autofluorescência demonstrou hipo e hiperautofluorescência em ambos os olhos, na mesma topografia das lesões detectadas na retinografia. A angiofluoresceínografia mostrou hipofluorescência na fase inicial do exame e hiperfluorescência tardia das lesões placoides em ambos os olhos. A tomografia de coerência óptica de domínio espectral de ambos os olhos revelou elevações irregulares do epitélio pigmentado da retina com descontinuação da zona elipsoide na área macular. Três meses após o início do tratamento para infecção por Bartonella, as lesões placoides tornaram-se atróficas e hiperpigmentadas, e a tomografia de coerência óptica revelou perda das camadas externas da retina e do epitélio pigmentado da retina na topografia das lesões maculares em ambos os olhos.

Use of surgical videos available on social media among retina surgeons: results of a vitreoretinal specialist survey / Uso de vídeos cirúrgicos nas mídias sociais entre cirurgiões de retina: resultados de uma pesquisa com especialista em retina

ABSTRACT Purpose: This study aimed to assess and interpret how vitreoretinal surgeons use surgical videos available on social media as complementary learning tools to improve, review, or update their abilities, considering their different levels of expertise. Methods: In this cross-sectional survey, an online survey was sent to vitreoretinal specialists and fellows. Results: This survey included 258 participants, of whom 53.88% had been in practice for >10 years (senior surgeons), 29.07% between 4 and 10 years (young surgeons), and 17.05% for <3 years (surgeons in training). Retinal surgical videos available on social media were used by 98.84% of the participants (95% confidence interval, 97.52%-100%). YouTube (91%) was the most common source of videos, and surgeons in training watched more videos on YouTube than senior surgeons. Regarding the preferred method when preparing for a procedure, 49.80% of the participants watched surgical videos available on social media, 26.27% preferred to "consult colleagues", and 18.82% preferred to seek information in scientific articles. Participants valued the most the "image quality" (88%) and presence of "surgical tips and tricks" (85%). Conclusion: Surgical videos can provide benefits in acquiring strategic skills, such as decision-making, surgical planning, and situational awareness. Retina surgeons used them as teaching aids regardless of their level of expertise, despite being relatively more valuable to surgeons in training or young surgeons.

RESUMO Objetivo: Avaliar e interpretar como os cirurgiões vitreorretinianos utilizam os vídeos cirúrgicos disponíveis nas mídias sociais como ferramentas complementares de aprendizagem para melhorar, revisar ou atualizar suas habilidades, considerando seus diferentes níveis de especialização. Métodos: Nesta pesquisa transversal, um survey online foi enviado à especialistas e aprendizes na área vítreo-retiniana. Resultados: Esta pesquisa incluiu 258 participantes, dos quais 53,88% atuavam há mais de 10 anos (cirurgiões seniores), 29,07% entre 4 e 10 anos (cirurgiões jovens) e 17,05% há menos de 3 anos (cirurgiões em treinamento). Vídeos cirúrgicos de retina nas mídias sociais foram usados por 98,84% dos participantes (intervalo de confiança de 95%, 97,52%-100%). A fonte mais comum de acesso aos vídeos foi o YouTube (91%), e o grupo de cirurgiões com menos de 3 anos de experiência assistiu mais vídeos no YouTube em comparação aos cirurgiões seniores. Assistir a vídeos cirúrgicos nas redes sociais foi o método preferido na preparação para um procedimento para 49,80% dos participantes versus 26,27% que preferiram "consultar colegas" e 18,82% que preferiram buscar informações em artigos científicos. A "qualidade de imagem" (88%) e a presença de "dicas e truques cirúrgicos" (85%) foram as características dos vídeos mais valorizadas pelos participantes. Conclusão: O uso de vídeos cirúrgicos pode trazer benefícios na aquisição de habilidades estratégicas, como tomada de decisão, planejamento cirúrgico e consciência situacional. Sua aplicação como auxiliar de ensino foi utilizada por cirurgiões de retina independentemente de seu nível de especialização, apesar de ser relativamente mais valioso para cirurgiões em formação ou com menos de 10 anos de experiência.

Heart Rate Reactivity to Acute Mental Stress is Associated With Parasympathetic Withdrawal and Adiposity in Firefighters

Abstract Background Firefighters are regularly exposed to stress and have a high incidence of cardiovascular events. Investigating cardiovascular and autonomic reactivity to acute mental stress (AMS) and its association with adiposity may contribute to explaining the increased cardiovascular risk in these professionals. Objectives To evaluate cardiovascular and autonomic reactivity to AMS in firefighters while considering adiposity parameters. Methods This study recorded the blood pressure and heart rate (HR) of twenty-five firefighters (38±8 years) at rest, while performing the Stroop color-word test to induce AMS, and recovery. Cardiac autonomic modulation (HR variability), baroreflex sensitivity (BRS — sequential method), and adiposity (electrical bioimpedance) were assessed. One-way or two-way analysis of variance followed by Tukey's post hoc test and multiple linear regression were performed. The significance level was P<0.05. Results The AMS increased mean arterial pressure (MAP — Δ16±13 mmHg) and HR (Δ14±7 bpm) ( P <0.05). These responses were associated with parasympathetic modulation withdrawal (RMSSD: baseline: 29.8±18 vs. AMS: 21.5±14 ms; High-frequency: baseline: 5.2±1.4 vs. AMS: 4.5±1.3 Ln ms 2 ; P <0.05) and decreased in the Up gain of the baroreflex (baseline: 8.9±5.1 vs. AMS: 6.3±3.0 mmHg/ms; P <0.05). Groups divided by HR reactivity peak showed parasympathetic modulation withdrawal only in firefighters with lower adiposity (RMSSD: baseline: 27.8±17.6 vs. AMS: 14.4±9.2 ms; High-Frequency: baseline: 5.3±1.2 vs. AMS: 3.8±1.4 Ln ms 2 ; P <0.05). Fat percentage (β = -0.499), BRS (β = 0.486), and sympathetic/parasympathetic balance (β = -0.351) were predictors of HR reactivity ( P <0.05). Conclusion Our results demonstrated that HR reactivity to AMS modulated by cardiac vagal withdrawal seems to be influenced by body composition in this group of firefighters.

Remoção endoscópica de corpo estranho ventricular em gallus gallus domesticus da raça brahma: relato de caso / Endoscopic removal of a ventricular foreign body in a brahma gallus domesticus: case report / Extracción endoscópica de un cuerpo extraño ventricular en un brahma gallus domesticus: informe de un caso

Relatos de ingestão de corpos estranhos dos mais diferentes materiais são comuns em aves, especialmente nas mais jovens. Os corpos estranhos podem causar intoxicação (dependendo da composição do material) ou mesmo perfuração do canal alimentar ou obstrução gastrintestinal. Quando há suspeita de ingestão de corpos estranhos, exames de imagem como a radiologia, ultrassonografia e endoscopia são ferramentas valiosas para o diagnóstico. Objetivou-se relatar um caso de uma ave da espécie Gallus gallus domesticus, raça Brahma, sete meses de idade, macho, pesando 4,3 Kg com quadro de sensibilidade na cavidade corporal e histórico de regurgitação, hiporexia e prostração há cinco dias. As radiografias simples indicaram a presença de corpo estranho radiopaco (parafuso) alojado na região do ventrículo (moela). Após tratamento clínico com lavagens gástricas por cinco dias sem êxito, optou-se por realizar uma endoscopia digestiva alta sob anestesia geral com quetamina e isoflurano. O corpo estranho foi satisfatoriamente removido com pinça de alça de polipectomia e a ave apresentou rápida melhora clínica sem complicações. A endoscopia mostrou-se um procedimento pouco invasivo e eficaz para a resolução do presente caso. Os clínicos veterinários de aves devem considerar a possibilidade de usar a endoscopia como ferramenta para diagnóstico e resolução de corpos estranhos no canal alimentar das aves.(AU)

Reports of ingestion of foreign bodies from most different materials are common in birds, especially younger ones. Foreign bodies can cause intoxication (depending on the composition of the material) or even perforation of the alimentary canal and gastrointestinal obstruction. When foreign body ingestion is suspected, imaging tests such as radiology, ultrasound, and endoscopy are valuable diagnostic tools. The objective of this paper was to report a case of an avian of the species Gallus gallus domesticus, Brahma breed, seven months old, male, weighing 4.3 kg, with sensitivity in the body cavity, and a history of regurgitation, hyporexia, and prostration for five days. Plain radiographs indicated the presence of a radiopaque foreign body (screw) lodged in the ventricle region (gizzard). After clinical treatment with gastric lavages for five days without success, it was decided to perform an upper digestive endoscopy under general anesthesia with ketamine and isoflurane. The foreign body was satisfactorily removed with polypectomy loop forceps, and the bird showed rapid clinical improvement without complications. Endoscopy proved to be a minimally invasive and effective procedure for resolving the present case. Avian veterinary practitioners may consider using endoscopy to diagnose and resolve foreign bodies in the alimentary canal of birds.(AU)

Changes in lifestyle behaviors during the COVID-19 pandemic in children and adolescents with congenital heart disease / Mudanças nos comportamentos de estilo de vida durante a pandemia COVID-19 em crianças e adolescentes com cardiopatia congênita

Abstract Objective: To describe the changes in lifestyle behaviors during the COVID-19 pandemic in children and adolescents with congenital heart disease and to investigate the association of congenital heart disease complexity with lifestyle behavior changes. Methods: Cross-sectional study with 127 children and adolescents with congenital heart disease, who underwent cardiac procedure (mean postoperative time: 10.11±3.13 years), conducted between December 2020 and January 2021. Lifestyle behaviors, such as dietary intake, physical activity, sedentary behavior, and sleep, were assessed through telephone interview based on validated questionnaires. Dietary patterns were identified using principal component analysis. Frequency of general and specific combinations of healthy and unhealthy lifestyle behavior changes was evaluated. Multinomial logistic regressions were used to test the association between congenital heart disease complexity and changes in lifestyle behavior. Results: The main lifestyle behaviors acquired during pandemic were: 83.5% decreased physical activity; 37.0% increased sedentary behavior; 26.0% slept more than usual; and 23.6% adopted a less-healthy dietary pattern. Almost half of the participants (41.8%) had at least one unhealthy change in lifestyle behavior. Complex congenital heart diseases were associated with increased sedentary behavior (OR 3.49, 95%CI 1.23-9.90). Conclusions: Children and adolescents with congenital heart disease had unhealthy lifestyle behavior during the pandemic, mainly in the form of reduced physical activity and increased sedentary behavior.

Resumo Objetivo: Descrever as mudanças nos estilos de vida durante a pandemia em crianças e adolescentes com cardiopatia congênita e investigar a associação da complexidade da cardiopatia congênita com as mudanças de estilo de vida. Métodos: Estudo transversal com 127 crianças e adolescentes com cardiopatia congênita, que realizaram procedimento cardíaco (tempo médio de pós-operatório: 10,11 (3,13) anos), realizado entre dezembro de 2020 e janeiro de 2021. O estilo de vida (alimentação, atividade física, comportamento sedentário e sono) foi avaliado por entrevista telefônica, com base em questionários validados. Padrões alimentares foram identificados por meio da análise de componentes principais. Frequência de combinações gerais e específicas de mudanças de estilo de vida saudável e não saudável foram avaliadas. Regressões logísticas multinominais foram utilizadas para testar associações. Resultados: Os principais comportamentos de estilo de vida adquiridos durante a pandemia foram: 83,5% reduziram a atividade física, 37,0% aumentaram o comportamento sedentário, 26,0% dormiram mais e 23,6% mudaram para um padrão alimentar menos saudável. Quase metade (41,8%) dos participantes teve pelo menos uma mudança não saudável no estilo de vida. Cardiopatias congênitas complexas foram associadas ao aumento do comportamento sedentário durante a pandemia (odds ratio 3,49, IC95% 1,23-9,90). Conclusões: Crianças e adolescentes com cardiopatia congênita apresentaram estilo de vida não saudável durante a pandemia, principalmente na forma de redução da atividade física e aumento do comportamento sedentário.

Measurement of extracapsular extension in sentinel lymph node as a possible predictor of residual axillary disease in breast cancer

Abstract Background The presence of Extracapsular Extension (ECE) in the Sentinel Lymph Node Biopsy (SLNB) is still a doubt in the literature. Some studies suggest that the presence of ECE may be related to a greater number of positive axillary lymph nodes which could impact Disease Free Survival (DFS) and Overall Survival (OS). This study searches for the clinical significance of the ECE. Methods Retrospective cohort comparing the presence or absence of ECE in T1-2 invasive breast cancer with positive SLNB. All cases treated surgically at the Cancer Institute of the State of São Paulo (ICESP) between 2009 and 2013 were analyzed. All patients with axillary disease in SLNB underwent AD. Outcomes Identify the association between the presence and length of ECE and additional axillary positive lymph nodes, OS and DFS between both groups. Results 128 patients with positive SLNB were included, and 65 had ECE. The mean metastasis size of 0.62 (SD = 0.59) mm at SLNB was related to the presence of ECE (p < 0.008). The presence of ECE was related to a higher mean of positive sentinel lymph nodes, 3.9 (± 4.8) vs. 2.0 (± 2.1), p = 0.001. The median length of follow-up was 115 months. The OS and DFS rates had no differences between the groups. Conclusion The presence of ECE was associated with additional positive axillary lymph nodes in this study. Therefore, the OS and DFS were similar in both groups after 10 years of follow-up. It is necessary for additional studies to define the importance of AD when SLNB with ECE.

HDL-Cholesterol in Children and Adolescents with Congenital Heart Disease

Abstract Background Children and adolescents with congenital heart disease may be more likely to develop atherogenic cardiovascular diseases in adulthood. Therefore, the early identification of risk factors and intervention in childhood may be crucial for a good quality of life and longevity. Objectives To describe the distribution of high-density lipoprotein-cholesterol (HDL-c) levels and its association with socioeconomic, clinical and cardiovascular risk factors in children and adolescents with congenital heart disease. Methods Cross-sectional study with children and adolescents aged between 5 and 18 years, with congenital heart disease. Socioeconomic, clinical and cardiovascular risk factors were evaluated. HDL-c concentrations were evaluated by the direct method and categorized as desirable (>45 mg/dL), borderline (40-45 mg/dL) and low (<40 mg/dL). We also assessed the "undesirable" levels, consisting of the sum of "borderline" and "low" values for comparative purposes. The multivariate logistic regression analysis was used to evaluate the factor associated with undesirable HDL-c levels. A p<0.05 value was adopted as statistically significant. Results Mean HDL-c was 51.2 mg/dL (SD 12.6), with a prevalence of 33.2% of undesirable HDL-c. In the multivariate analysis, C-reactive protein levels ≥ 3mg/dL (OR 3.26; 95% CI 1.32-8.04), age ≥ 10 years old (OR: 2.11; 95% CI 1.12-3.99) and undesirable levels of triglycerides (OR 2.21; 95% CI 1.13-4.75) were associated with undesirable HDL-c. Conclusion In this sample of children and adolescents with congenital heart disease, almost one third presented low or borderline HDL-c levels. Age ≥10 years, C-reactive protein and triglycerides were associated with undesirable HDL-c levels. These factors should be considered in the prevention of cerebrovascular diseases in adulthood in this population.

Association between bone mineral density and content and physical growth parameters among children and adolescents diagnosed with HIV: a cross-sectional study

ABSTRACT BACKGROUND: During childhood and adolescence, there are significant increases in bone mineral content (BMC) and bone mineral density (BMD). OBJECTIVE: To investigate physical growth parameters associated with BMD and BMC among children and adolescents diagnosed with human immunodeficiency virus (HIV). DESIGN AND SETTING: Cross-sectional study conducted in Florianópolis, Brazil, among 63 children and adolescents (aged 8-15 years) diagnosed with HIV. METHOD: BMD, BMC and fat percentage z score were evaluated using dual X-ray absorptiometry. Age/height z score and body mass index (BMI)/age z score were obtained in accordance with international recommendations, and bone age was obtained through hand-wrist radiography. Sex, family income, information on HIV infection (T CD4+ lymphocyte count, viral load and type of antiretroviral therapy, moderate-vigorous physical activity and sedentary behavior) were used as adjustment variables in the analyses. Simple and multiple linear regression analyses were performed, with a significance level of P ≤ 0.05. RESULTS: Subtotal BMD (without the head region) was directly associated with bone age, BMI/age z score and fat percentage z score, even after adjusting for covariates. Subtotal BMC/height was directly associated with bone age, height/age z score, BMI/age z score and fat percentage z score, even after adjusting for covariates. CONCLUSION: Subtotal BMD and subtotal BMC/height were directly associated with physical growth indicators among children and adolescents diagnosed with HIV.

What anthropometric indicators are associated with insulin resistance? Cross-sectional study on children and adolescents with diagnosed human immunodeficiency virus

ABSTRACT BACKGROUND: Studies that test associations between anthropometric indicators and insulin resistance (IR) need to provide better evidence in the context of the pediatric population (children and adolescents) with human immunodeficiency virus (HIV), as anthropometric indicators present a better explanation of the distribution of body fat. OBJECTIVE: To test the associations between anthropometric indicators and insulin resistance (IR) among children and adolescents diagnosed with HIV. DESIGN AND SETTING: Cross-sectional study on 65 children and adolescents (8-15 years) infected with HIV through vertical transmission conducted at the Joana de Gusmão Children's Hospital, Florianópolis, Brazil. METHODS: The anthropometric indicators measured were the abdominal (ASF), triceps (TSF), subscapular (SSF) and calf (CSF) skinfolds. The relaxed arm (RAC), waist (WC) and neck (NC) circumferences were also measured. Body mass index (BMI) was calculated from the relationship between body mass and height. IR was calculated through the Homeostasis Model Assessment for Insulin Resistance (HOMA-IR). Simple and multiple linear regression analyses were used. RESULTS: After adjustment for covariates (sex, bone age, CD4+ T lymphocytes, CD8+ T lymphocytes, viral load, and physical activity), associations between IR and models with SSF and CSF remained. Each of these explained 20% of IR variability. For females, in the adjusted analyses, direct associations between IR and models with ASF (R² = 0.26) and TSF (R² = 0.31) were observed. CONCLUSIONS: SSF and CSF in males and ASF and TSF in females were associated with IR in HIV-infected children and adolescents.

Un enfoque digital para restaurar un diente anterior traumatizado durante la pandemia COVID-19: reporte del caso / A digital approach to restore a traumatized anterior tooth during the COVID-19 pandemic: A clinical report

Los profesionales de la salud oral tienen un mayor riesgo de infección con el nuevo coronavirus 2019 (COVID-19), debido a la comunicación cercana a la cavidad oral y la exposición a saliva, sangre y otros fluidos corporales. Los enfoques digitales pueden reducir el tiempo clínico y contribuir a limitar el riesgo de infección. El objetivo del presente trabajo es presentar un enfoque digital para restaurar un diente anterior traumatizado, durante la pandemia de COVID-19. Paciente sexo feminino de 28 años, con movilidad anormal de la pieza 1.1 y antecedente de traumatismo dental en la adolescencia. Se realizó una evaluación inicial para detectar signos y síntomas de una posible infección por COVID-19. Las imágenes de la tomografía computarizada mostraron fractura coronaria y presencia de reabsorción cervical externa en el incisivo central derecho. El plan de tratamiento consistió en la rehabilitación del diente fracturado a través de una restauración retenida con un poste de fibra de vidrio, usando un abordaje digital por medio de un escáner intraoral con diseño y fabricación asistido por computadora (CAD/CAM). Los enfoques digitales en odontología podrían contribuir a reducir el riesgo de infección por COVID-19 en pacientes y dentistas durante los tratamientos restauradores.

Dental professionals are at increased risk of infection with the new coronavirus 2019 (COVID-19) due to face-to-face communication and exposure to saliva, blood and other body fluids. Digital approaches can reduce clinical time and contribute to limiting the risk of infection. The objective of this work was to report a digital approach to restoring a traumatized anterior tooth during the COVID-19 pandemic. A 28-year-old female with abnormal mobility in the crown of an upper anterior tooth with history of dental trauma in the adolescence. An initial screening was performed to check for signs and symptoms of possible COVID-19 infection. Cone Beam Computed Tomography images showed a crown fracture and the presence of external cervical resorption in the right permanent central incisor. The treatment plan consisted of rehabilitation of the fractured tooth through a restoration retained with a fiberglass post with a digital approach using an intraoral scanner, and computer-aided design and fabrication - CAD/CAM. Digital approaches in dentistry including intraoral scanners and CAD/CAM could contribute to reducing the risk of COVID-19 infection in patients and dentists during restorative treatments.

Acute effects of different intensities resistance training on inflammatory markers of women with severe obesity / Efeitos agudos de treinamento de força com diferentes intensidades sobre marcadores inflamatórios de mulheres com obesidade severa

ABSTRACT This study objective to compare the acute effects between one resistance training bout with high versus moderate intensities on inflammatory markers in women with severe obesity. Experimental crossover study, performed with adult women with severe obesity (BMI ≥ 40.0 kg/m²; age ≥ 18 years old). Each participant performed a high and moderate intensity resistance training (HIRT and MIRT, respectively) with an interval of 7 days between bouts. Four exercises were performed in the both protocols, with total training volume equalized. MIRT consisted of 3 sets of 8 repetitions each, with an intensity of 75% of 1RM, while HIRT consisted of 2 sets of 6 repetitions, followed by a 20-second rest, with a new performance of 2 to 3 repetitions, with one more rest of 20s and finishing with 2 to 3 more repetitions, at an intensity of 85% of 1RM. Blood samples were collected before, 15 minutes after and 24 hours after both training protocols. The inflammatory markers analyzed were IL-2, IL-4, IL-6, IL-10, TNF-α and IFN-γ. Nine participants have completed the intervention (n=9; 35.2 ± 10.93 years old; BMI = 48.3 ± 5.06 kg/m²). The Mann-Whitney U test showed that there was no significant difference between the HIRT and MIRT in the concentration of markers. Friedman's test did not report significant differences between intragroup measures for the HIRT as well as MIRT. This research suggests that a single session of high or moderate intensity resistance training does not change the inflammatory status of women with severe obesity.

RESUMO Este estudo objetivou comparar os efeitos agudos entre uma sessão de treinamento de força de alta versus moderada intensidade sobre marcadores inflamatórios em mulheres com obesidade severa. Estudo experimental do tipo cross-over, realizado com mulheres adultas com obesidade severa (IMC ≥ 40,0 kg/m²; idade ≥ 18 anos). Cada participante realizou uma sessão de treinamento de força de alta e de moderada intensidade (HIRT e MIRT, respectivamente) com intervalo de 7 dias entre as sessões. Quatro exercícios foram realizados em ambos os protocolos, com volume total de treino equalizado. O MIRT consistiu em 3 séries de 8 repetições cada, com intensidade de 75% de 1RM, enquanto o HIRT consistiu em 2 séries de 6 repetições, seguidas de um descanso de 20 segundos, com nova execução de 2 a 3 repetições, com mais um descanso de 20s e finalização com mais 2 a 3 repetições, com intensidade de 85% de 1RM. Amostras de sangue foram coletadas antes, 15 minutos após e 24 horas após ambos os protocolos de treino. Os marcadores inflamatórios analisados foram IL-2, IL-4, IL-6, IL-10, TNF-α e IFN-γ. Nove participantes completaram a intervenção (n=9; 35,2 ± 10,93 anos; IMC = 48,3 ± 5,06 kg/m²). O teste U de Mann-Whitney mostrou que não houve diferença significativa entre HIRT e MIRT na concentração dos marcadores. O teste de Friedman não mostrou diferenças significativas entre as medidas intragrupo para HIRT e MIRT. Esta pesquisa sugere que uma única sessão de treinamento de força de alta ou moderada intensidade não altera o estado inflamatório de mulheres com obesidade severa.

Muscle endurance of Brazilian children and adolescents: a systematic review of the literature / Resistência muscular de crianças e adolescentes brasileiros: uma revisão sistemática da literatura

ABSTRACT Muscle endurance (ME) is considered to be an important indicator of health-related fitness in childhood and adolescence. The present study aimed to identify and summarize the evidence on the prevalence of adequate ME in Brazilian children and adolescents (6 to 18 years old). A systematic search of studies published from 2009 to 2019 was performed in six databases (LILACS; SciELO; SportDiscus; Medline/PubMed; Web of Science; Scopus). We found 16,168 articles, 20 of which met the eligibility criteria and were included in this review for data extraction and assessment of their risk of bias. Among the 23,805 children and adolescents participating in the studies, 43.5% of the total (43.7% of boys and 41.0% of girls) had adequate abdominal ME. Different test batteries were reported, the main ones being PROESP/BR®, FITNESSGRAM®, and AAHPERD®. Most studies were carried out in the South (50.0%) and Southeast (20.0%) regions of Brazil. Regarding the distribution of studies by geographic region and human development index (HDI), there were no disparities in ME between studies conducted in regions with a lower HDI (43.1% for the Northeast and 32.2% for the North) and those with a higher HDI (46.8% for the South and 33.1% for the Southeast). We conclude that less than half of Brazilian children and adolescents of both genders have an abdominal ME adequate for health, with ​​slightly lower values among females.

RESUMO A resistência muscular (RM) tem sido considerada um importante indicador da aptidão relacionada a saúde na infância e adolescência. O estudo teve como objetivo identificar e sumarizar as evidências sobre a prevalência de RM adequada em crianças e adolescentes (6 a 18 anos) no Brasil. Foi realizada uma busca sistemática em seis bases de dados (LILACS; Scielo; SportDiscus; Medline/Pubmed; Web of Science; Scopus), de estudos publicados no período de 2009 a 2019. Foram encontrados 16.168 artigos, sendo que 20 estudos preencheram os critérios de elegibilidade e foram incluídos na presente revisão para extração dos dados e avaliação quanto o seu risco de viés. Entre as 23.805 crianças e adolescentes participantes nos estudos, 43,5% do total (43,7% dos meninos e 41,0% das meninas) apresentaram RM abdominal adequada. Diferentes baterias de testes foram identificadas, sendo as principais PROESP/BR®, FITNESSGRAM® e AAHPERD®. A maioria dos estudos foram realizados de na região Sul (50,0%) e Sudeste (20,0%) do Brasil. Em relação as distribuições dos estudos pelas regiões geográficas e índices de desenvolvimento humano (IDH), não houveram disparidades na RM entre os estudos nas regiões com menores IDH (Nordeste 43,1% e Norte 32,2%) e as de maiores IDH (Sul 46,8% e Sudeste 33,1%). Conclui-se que menos da metade das crianças e adolescentes brasileiras de ambos os sexos possuem uma RM abdominal adequada para a saúde, com valores ligeiramente inferiores no sexo feminino.

Flexibility of Brazilian children and adolescents: a systematic review of the literature / Flexibilidade de crianças e adolescentes brasileiros: uma revisão sistemática da literatura

abstract Flexibility is related to specific tissue properties of the body, which aim to determine the maximum range of motion of the joints without injury. This study aimed to identify and summarize the evidence on prevalence of adequate levels of flexibility in Brazilian children and adolescents (6 to 19 years old). We performed a systematic search of studies published from 2009 to 2019 in six databases (MEDLINE/PubMed; Scopus; SportDiscus; LILACS; Web of Science; SCIELO). Fourteen studies that compiled data from 11,666 participants in seven different Brazilian states were included. All studies conducted sit and reach tests to assess flexibility. Among all the children and adolescents in the analyzed studies, 58.9% of the total (62.0% of boys and 50.9% of girls) had adequate flexibility. We conclude that more than half of Brazilian children and adolescents have adequate flexibility for health.

resumo A flexibilidade está relacionada com propriedades específicas teciduais que permitem a amplitude máxima de movimento articular sem a presença de lesão. O presente estudo teve como objetivo identificar e sintetizar as evidências sobre a prevalência de níveis adequados de flexibilidade em crianças e adolescentes brasileiros (6 a 19 anos). Foi realizada uma busca sistematizada de estudos publicados de 2009 a 2019 em seis bases de dados (MEDLINE/PubMed; Scopus; SportDiscus; LILACS; Web of Science; SCIELO). Foram incluídos 14 estudos que compilaram dados de 11.666 participantes em sete estados brasileiros diferentes. Todos os estudos realizaram teste de sentar e alcançar para avaliar a flexibilidade. Dentre todas as crianças e adolescentes dos estudos analisados, 58,9% do total (62,0% dos meninos e 50,9% das meninas) apresentaram flexibilidade adequada. Concluímos que mais da metade das crianças e adolescentes brasileiros possuem flexibilidade adequada para a saúde.

Epidemiology of corneal transplantation before achieving the Zero Queue / Epidemiologia do transplante de córnea antes de atingir a Fila Zero

ABSTRACT Objective: To outline the epidemiological profile of cornea donors and recipients before reaching queue zero. Methods: Epidemiological study, of quantitative approach, with transversal, analytical design, analyzing database records from the Health Secretary of the State of Ceará, from 2013 to 2015. Results: We obtained 1,558 cornea donors and 2,287 cornea recipients from 2013 to 2015. Most donors were male, capital residents, from 21 to 40 years old. Of donated eyeballs, 14.52% were disposed, due to poor condition, infiltration or positive serology. The recipients were predominantly women over 60 years old. The procedures were mostly elective, due to bullous keratopathy (28%). Regarding emergency transplants, ulcer (38.51%) and retransplant (35.14%) were most prevalent. Predominantly, transplants were funded by the Unified Health System. Conclusion: The majority of patients who were submitted to corneal transplantation are senile, especially females, therefore should be cautiously observed. On the other hand, donors are mainly male and young, reflecting the high number of tragic accidents. The surgery for bullous keratopathy is the most frequent among elective transplants, while the ulcer surgery is the main cause of emergency procedures. The fact that most surgeries were financed by the Unified Health System reflects the importance of this system.

RESUMO Objetivo: Traçar o perfil epidemiológico dos doadores e receptores de córnea antes de atingir a Fila Zero. Métodos: Estudo epidemiológico, de abordagem quantitativa, com delineamento transversal e analítico, analisando registros da base de dados da Secretaria de Saúde do Estado do Ceará, de 2013 a 2015. Resultados: Foram obtidos 1.558 doadores de córnea e 2.287 receptores de córnea, de 2013 a 2015. A maioria dos doadores era homem, procedente da capital, de 21 a 40 anos. Dentre os globos oculares doados, 14,52% foram descartados por má condição, infiltração ou sorologia positiva. Os receptores eram predominantemente mulheres acima de 60 anos de idade. Os procedimentos foram majoritariamente eletivos, devido à ceratopatia bolhosa (28%). Já para transplantes de emergência, a úlcera (38,51%) e o retransplante (35,14%) foram os mais prevalentes. Em geral, os transplantes foram custeados pelo Sistema Único de Saúde. Conclusão: A maioria dos pacientes submetidos a transplantes de córnea foram do grupo etário senil, principalmente do sexo feminino, devendo esse grupo ser observado com cautela. Em contrapartida, os doadores eram, principalmente, homens e jovens, refletindo o alto número de pessoas que morrem devido a acidentes trágicos. A cirurgia de ceratopatia bolhosa foi a mais frequente dentre os transplantes eletivos; já a de úlcera foi a principal causa dos procedimentos de emergência. O fato de a maioria das cirurgias ter sido financiada pelo Sistema Único de Saúde reflete a importância desse sistema.

Doege-Potter syndrome associated to metastatic solitary fibrous tumor

ABSTRACT Solitary fibrous tumor (SFT) is a rare fibroblastic mesenchymal neoplasm with an estimated annual incidence of 0.35 per 100,000 individuals. Doege-Potter syndrome is a paraneoplastic syndrome related to solitary fibrous tumor clinically characterized by hypoglycemia, occurring in less than 5% of cases. Herein, we report a case of metastatic SFT associated with recurrent severe hypoglycemia. A 43-year-old male with a noncontributory medical history presented with a painless and progressive growing mass in the right thigh. The histological evaluation rendered the diagnosis of SFT, and tumor resection was performed. One year after the operation, on the oncological follow-up, he was admitted to the emergency unit, manifesting an early-morning seizure associated with a severe hypoglycemia. The laboratory findings of non-islet cell tumor hypoglycemia (NICTH) in the background of a relapsed metastatic solitary fibrous tumor were consistent with the diagnosis of Doege-Potter syndrome. Hepatic embolization associated with oral glucocorticoid was an efficient palliative treatment to control the hypoglycemic crisis and allow hospital discharge.
