    Functional assessment of sensitivity is essential to analyzing the status, recovery, and effectiveness of the treatment program for patients who have suffered losses due to physical and/or sensory disability after peripheral nerve injuries. Such losses of sensation lead to a significant loss of hand function. Objective: The purpose of the present study was to establish a correlation between functional and sensory threshold tests after a peripheral nerve lesion in the hand. Method: Fourteen men aged 18 to 40 years, who had bruises and cut injuries at the volar region of the wrist resulting in median nerve lesion, were selected for study. All the subjects were at least 1-year post-surgery. An esthesiometer SORRI® and a modified Moberg pick-up test were used. The test was divided into two phases, one with eyes open and the other with eyes closed. Also, the same test was performed by two different examiners. It was a “blinded” test that was performed three times, being repeated by the examiners according to a random sequence kept during the entire evaluation. Mean age and standard deviation were obtained during analysis in which Pearson’s coefficient was calculated and the non-parametric Mann-Whitney test was applied at 5% significance. Results: The mean age was 27.14 years with a standard deviation of 6.43 years, with the lesions being more frequently seen in men aged 21 to 30 years. Also, 64% of the cases involved lesion of the dominant hand. Pearson’s coefficient (r) regarding the correlation between sensory threshold test and Moberg pick-up test ranged from 0.5 to 0.7, which was statistically significant. Confidence intervals and p-values obtained from the Mann-Whitney test showed no statistically significant differences. Conclusion: One can conclude, therefore, that despite lacking standardized measures, the Moberg pick-up test correlated with the functional test. However, further studies are needed to support validation and reliability of the two methods.A avaliação funcional da sensibilidade é essencial para analisar o estado, recuperação, e efetividade do programa de tratamento em pacientes que sofreram perdas decorrentes de deficiência motora e/ou sensitiva, após lesões nervosas periféricas. Estas lesões geram a interrupção das sensações ocasionando a perda da sensibilidade e uma significante perda funcional da mão. Objetivo: O objetivo deste estudo foi correlacionar o teste funcional Pick-Up de Moberg com o teste de limiar sensitivo Estesiômetro SORRI® na reconstrução do nervo mediano. Método: Foram analisados 14 homens com idade entre 18 e 40 anos que sofreram ferimento corto-contuso na região volar do punho e tratamento cirúrgico há pelo menos um ano de pós-operatório. Foram utilizados para a avaliação da sensibilidade cutânea o Estesiômetro SORRI® e o teste Pick-Up de Moberg modificado, no qual a avaliação foi dividida em duas fases, olhos abertos e fechados, ambas realizadas com a mão dominante e não dominante, e em duas etapas com diferentes avaliadores, sendo repetidas três vezes em cada mão. A sequência dos avaliadores foi sorteada e mantida durante toda a avaliação. Na análise dos dados foi utilizado o coeficiente de Pearson e aplicado o teste não-paramétrico de Mann-Whitney com o nível de significância α = 0,05. Resultados: A média da idade foi de 27,14 anos (± 6,43), com maior frequência entre 21 a 30 anos sendo que 64% apresentaram lesão na mão dominante. O coeficiente de Pearson (r) entre o Estesiômetro e o Pick-Up foi entre 0,5 e 0,7, com p-valor < 0,05. Os intervalos de confiança e p-valores dos testes de Mann-Whitney não indicaram diferenças estatisticamente significantes. Conclusão: Apesar do teste Pick-Up de Moberg não possuir medidas padronizadas, na amostra estudada pode-se concluir que existe correlação entre o teste funcional e o teste de limiar sensitivo. Novos estudos são necessários para a validação e confiabilidade de ambos os métodos

    Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050.

    Diretriz sobre Diagnóstico e Tratamento da Cardiomiopatia Hipertrófica – 2024

    Hypertrophic cardiomyopathy (HCM) is a form of genetically caused heart muscle disease, characterized by the thickening of the ventricular walls. Diagnosis requires detection through imaging methods (Echocardiogram or Cardiac Magnetic Resonance) showing any segment of the left ventricular wall with a thickness > 15 mm, without any other probable cause. Genetic analysis allows the identification of mutations in genes encoding different structures of the sarcomere responsible for the development of HCM in about 60% of cases, enabling screening of family members and genetic counseling, as an important part of patient and family management. Several concepts about HCM have recently been reviewed, including its prevalence of 1 in 250 individuals, hence not a rare but rather underdiagnosed disease. The vast majority of patients are asymptomatic. In symptomatic cases, obstruction of the left ventricular outflow tract (LVOT) is the primary disorder responsible for symptoms, and its presence should be investigated in all cases. In those where resting echocardiogram or Valsalva maneuver does not detect significant intraventricular gradient (> 30 mmHg), they should undergo stress echocardiography to detect LVOT obstruction. Patients with limiting symptoms and severe LVOT obstruction, refractory to beta-blockers and verapamil, should receive septal reduction therapies or use new drugs inhibiting cardiac myosin. Finally, appropriately identified patients at increased risk of sudden death may receive prophylactic measure with implantable cardioverter-defibrillator (ICD) implantation.La miocardiopatía hipertrófica (MCH) es una forma de enfermedad cardíaca de origen genético, caracterizada por el engrosamiento de las paredes ventriculares. El diagnóstico requiere la detección mediante métodos de imagen (Ecocardiograma o Resonancia Magnética Cardíaca) que muestren algún segmento de la pared ventricular izquierda con un grosor > 15 mm, sin otra causa probable. El análisis genético permite identificar mutaciones en genes que codifican diferentes estructuras del sarcómero responsables del desarrollo de la MCH en aproximadamente el 60% de los casos, lo que permite el tamizaje de familiares y el asesoramiento genético, como parte importante del manejo de pacientes y familiares. Varios conceptos sobre la MCH han sido revisados recientemente, incluida su prevalencia de 1 entre 250 individuos, por lo tanto, no es una enfermedad rara, sino subdiagnosticada. La gran mayoría de los pacientes son asintomáticos. En los casos sintomáticos, la obstrucción del tracto de salida ventricular izquierdo (TSVI) es el trastorno principal responsable de los síntomas, y su presencia debe investigarse en todos los casos. En aquellos en los que el ecocardiograma en reposo o la maniobra de Valsalva no detecta un gradiente intraventricular significativo (> 30 mmHg), deben someterse a ecocardiografía de esfuerzo para detectar la obstrucción del TSVI. Los pacientes con síntomas limitantes y obstrucción grave del TSVI, refractarios al uso de betabloqueantes y verapamilo, deben recibir terapias de reducción septal o usar nuevos medicamentos inhibidores de la miosina cardíaca. Finalmente, los pacientes adecuadamente identificados con un riesgo aumentado de muerte súbita pueden recibir medidas profilácticas con el implante de un cardioversor-desfibrilador implantable (CDI).A cardiomiopatia hipertrófica (CMH) é uma forma de doença do músculo cardíaco de causa genética, caracterizada pela hipertrofia das paredes ventriculares.

Naqueles sintomáticos, a obstrução do trato de saída do ventrículo esquerdo (OTSVE) é o principal distúrbio responsável pelos sintomas, devendo-se investigar a sua presença em todos os casos. Naqueles em que o ecocardiograma em repouso ou com Manobra de Valsalva não detecta gradiente intraventricular significativo (> 30 mmHg), devem ser submetidos à ecocardiografia com esforço físico para detecção da OTSVE.   Pacientes com sintomas limitantes e grave OTSVE, refratários ao uso de betabloqueadores e verapamil, devem receber terapias de redução septal ou uso de novas drogas inibidoras da miosina cardíaca. Por fim, os pacientes adequadamente identificados com risco aumentado de morta súbita podem receber medida profilática com implante de cardiodesfibrilador implantável (CDI)

    Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.

    Os aspectos epidemiológicos dos procedimentos cirúrgicos mostram as dimensões relativas ao comportamento e à evolução de problemas de saúde coletiva, com destaque para sua incidência, distribuição, e possível controle dos determinantes das próprias doenças e de seus fatores. Os aspectos epidemiológicos vêm buscando compreender melhor as doenças, suas características e seu comportamentos, no que se refere aos seus determinantes biológicos, sociais e ambientais. Dessa forma, a presente revisão sistemática teve como objetivo: mostrar os aspectos epidemiológicos dos procedimentos cirúrgicos. Foi realizada uma busca nas bases de dados Google acadêmico, Lilacs e Scientific Eletronic Online (Scielo), no qual os descritores foram: Saúde, Epidemiologia, Fatores de risco, 12 artigos foram utilizados neste estudo. Os resultados da revisão sistemática evidenciam que a frequente pressão da sociedade e da mídia em relação à aparência de seus corpos, faz com que cada vez mais indivíduos optem pelas cirurgias plásticas que algumas vezes não tem o resultado esperado, gerando mais impactos psicológicos aos pacientes
