Relato de um caso com rápida evolução e desfecho satisfatório em criança com provável Síndrome de Guillain- Barré

Introduction: Guillain-Barré Syndrome (GBS) is the most frequent cause of acute and sub-acute flaccid paralysis after polio eradication. Although rare, it is recognized as the leading cause of flaccid paralysis among the admissions to pediatric intensive care for acute neuromuscular diseases. Objective: To report the case of a 14-month-old male patient with a probable diagnosis of GBS with acute, myelinated motor sensitive neuropathy, with probable secondary axonal involvement, with rapid clinical recovery. Case Report: A male patient admitted in a reference hospital in the Federal District, Brazil, residing in the Integrated Development Region of the Federal District and Surroundings. The child was 14 months old and 8.6 kg, with an updated vaccination status and neuropsychomotor development appropriate for his age, with a condition of paresis in the lower limbs, without cognitive changes. After 14 hours of admission, due to the worsening of his clinical situation and the albumino-cytological dissociation identified by the analysis of cerebrospinal fluid, it was started immunotherapy with intravenous human immunoglobulin, 0.7g/kg/day for three days. Twenty four hours after start of treatment, the child showed a clinical improvement of his general condition. The patient was discharged after five days of hospitalization. After 76 days of discharge, there was a significant improvement in neuropsychomotor development, despite a slight delay in its development. Conclusion: Due to the rarity of Guillain-Barré Syndrome among young children, it is important that health professionals remain sensitive to capture and treat unusual cases in a timely manner. We also recommend that the identified cases be monitored carefully, in order to check if the Guillain-Barré Syndrome, and its variants, can explain developmental disorders a posteriori.Introdução: A Síndrome de Guillain-Barré (SGB) é a causa mais frequente de paralisia flácida aguda e subaguda desde a erradicação da poliomielite. Embora rara, é reconhecida como a principal causa de paralisia flácida entre pessoas internadas em terapia intensiva pediátrica por doenças neuromusculares agudas. Objetivo: Relatar um caso de paciente do sexo masculino, com 14 meses de idade, com diagnóstico provável de Síndrome de Guillain-Barré com neuropatia sensitivo motora, aguda, mielínica, com provável comprometimento axonal secundário, com rápida evolução e melhora.   Descrição do caso: Foi admitido em hospital público maternoinfantil de referência para o Distrito Federal um paciente masculino, residente na Região Integrada de Desenvolvimento do Distrito Federal e Entorno. A criança tinha 14 meses de idade e 8,6kg, situação vacinal atualizada e desenvolvimentoneurospicomotor adequado para a idade, com quadro de paresia em membros inferiores, sem alterações cognitivas. Após 14 horas da admissão, diante do agravamento do quadro clínico e da dissociação albomino-citológica identificada pela análise de líquido cefalo-raquidiano foi iniciada imunoterapia (imunoglobulina humana endovenosa, 0,7g/kg/dia por três dias). Após 24 horas do início do tratamento, a criança apresentou melhora em seu estado geral. O paciente teve alta hospitalar após cinco dias de internação. Após 76 dias da alta, foi constatada melhora significativa no desenvolvimento neuropsicomotor, apesar de leve atraso em seu desenvolvimento até o momento.   Conclusão: Diante da raridade de casos em crianças, é importante que os profissionais de saúde se mantenham sensíveis a captar e tratar os casos de maneira oportuna. Recomendamos ainda que os casos identificados sejam acompanhados cuidadosamente, afim de verificar se a SGB, esuas variantes, podem explicar transtornos de desenvolvimento à posteriori

Hemograma completo: ferramenta de diagnóstico na medicina veterinária / Complete hemogram: diagnostic tool in veterinary medicine

O hemograma completo é uma importante ferramenta para auxílio do profissional na clínica de cães e gatos. É o exame mais requerido nas consultas, sendo indispensável para diagnóstico e acompanhamento de doenças, emergências médicas ou cirúrgicas, entre outras situações. O hemograma completo traz informações sobre todas as células sanguíneas, e a principal função do sangue, é o carreamento de gases e substâncias para que todos os tecidos continuem em funcionamento adequado, e em segundo plano, protege e regula o corpo, para manutenção da homeostasia. Com o hemograma completo, pode-se reconhecer enfermidades em pacientes assintomáticos e ser tomadas decisões antes do seu agravamento, ou mesmo, estar ciente da homeostase do organismo do animal antes de um procedimento cirúrgico. Este trabalho avaliou o hemograma completo de 50 cães provenientes do atendimento clínico e do Projeto de Controle Populacional por meio de castração cirúrgica realizado no Hospital Veterinário da UFJ, discutindo as alterações encontradas e a importância do exame complementar na clínica de pequenos animais.

O uso de testes rápidos na rotina clínica veterinária / The use of quick tests in the veterinary clinical routine

O diagnóstico de doenças na clínica médica de pequenos animais pode se tornar um grande desafio ao médico veterinário devido à grande variedade de patógenos. A ocorrência de doenças sem sintomatologia clínica e muitas vezes devido à falta de procedimentos acessíveis que auxiliem no diagnóstico podem comprometer o sucesso do diagnóstico. Os exames conhecidos como testes rápidos podem ser uma excelente alternativa para auxiliar os profissionais nos diagnósticos de seus pacientes. O objetivo deste trabalho foi demonstrar a importância dos testes rápidos na rotina clínica de pequenos animais através de uma análise dos casos de solicitações dos exames no Hospital Veterinário da Universidade Federal de Jataí nos anos de 2018 e 2019 e seus resultados quanto a suspeita clínica foram testadas 52 amostras. Os testes comumente realizados no Hospital Veterinário da UFJ foram os Snap de Leishmania spp. ®, Snap para Giardia spp. ®, Snap Combo ® para detecção de FIV e FeLV e o Snap 4Dx ®, o qual faz a detecção de 4 diferentes antígenos, Dirofilaria immitis, Anaplasma phagocytophilum, Anaplasma platys, Borrelia burgdorferi e Ehrlichia canis

Coinfection with Different Trypanosoma cruzi Strains Interferes with the Host Immune Response to Infection

A century after the discovery of Trypanosoma cruzi in a child living in Lassance, Minas Gerais, Brazil in 1909, many uncertainties remain with respect to factors determining the pathogenesis of Chagas disease (CD). Herein, we simultaneously investigate the contribution of both host and parasite factors during acute phase of infection in BALB/c mice infected with the JG and/or CL Brener T. cruzi strains. JG single infected mice presented reduced parasitemia and heart parasitism, no mortality, levels of pro-inflammatory mediators (TNF-α, CCL2, IL-6 and IFN-γ) similar to those found among naïve animals and no clinical manifestations of disease. On the other hand, CL Brener single infected mice presented higher parasitemia and heart parasitism, as well as an increased systemic release of pro-inflammatory mediators and higher mortality probably due to a toxic shock-like systemic inflammatory response. Interestingly, coinfection with JG and CL Brener strains resulted in intermediate parasitemia, heart parasitism and mortality. This was accompanied by an increase in the systemic release of IL-10 with a parallel increase in the number of MAC-3+ and CD4+ T spleen cells expressing IL-10. Therefore, the endogenous production of IL-10 elicited by coinfection seems to be crucial to counterregulate the potentially lethal effects triggered by systemic release of pro-inflammatory mediators induced by CL Brener single infection. In conclusion, our results suggest that the composition of the infecting parasite population plays a role in the host response to T. cruzi in determining the severity of the disease in experimentally infected BALB/c mice. The combination of JG and CL Brener was able to trigger both protective inflammatory immunity and regulatory immune mechanisms that attenuate damage caused by inflammation and disease severity in BALB/c mice

Pervasive gaps in Amazonian ecological research

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. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

Worldwide trends in underweight and obesity from 1990 to 2022: a pooled analysis of 3663 population-representative studies with 222 million children, adolescents, and adults

Background Underweight and obesity are associated with adverse health outcomes throughout the life course. We estimated the individual and combined prevalence of underweight or thinness and obesity, and their changes, from 1990 to 2022 for adults and school-aged children and adolescents in 200 countries and territories. Methods We used data from 3663 population-based studies with 222 million participants that measured height and weight in representative samples of the general population. We used a Bayesian hierarchical model to estimate trends in the prevalence of different BMI categories, separately for adults (age ≥20 years) and school-aged children and adolescents (age 5–19 years), from 1990 to 2022 for 200 countries and territories. For adults, we report the individual and combined prevalence of underweight (BMI <18·5 kg/m2) and obesity (BMI ≥30 kg/m2). For schoolaged children and adolescents, we report thinness (BMI <2 SD below the median of the WHO growth reference) and obesity (BMI >2 SD above the median). Findings From 1990 to 2022, the combined prevalence of underweight and obesity in adults decreased in 11 countries (6%) for women and 17 (9%) for men with a posterior probability of at least 0·80 that the observed changes were true decreases. The combined prevalence increased in 162 countries (81%) for women and 140 countries (70%) for men with a posterior probability of at least 0·80. In 2022, the combined prevalence of underweight and obesity was highest in island nations in the Caribbean and Polynesia and Micronesia, and countries in the Middle East and north Africa. Obesity prevalence was higher than underweight with posterior probability of at least 0·80 in 177 countries (89%) for women and 145 (73%) for men in 2022, whereas the converse was true in 16 countries (8%) for women, and 39 (20%) for men. From 1990 to 2022, the combined prevalence of thinness and obesity decreased among girls in five countries (3%) and among boys in 15 countries (8%) with a posterior probability of at least 0·80, and increased among girls in 140 countries (70%) and boys in 137 countries (69%) with a posterior probability of at least 0·80. The countries with highest combined prevalence of thinness and obesity in school-aged children and adolescents in 2022 were in Polynesia and Micronesia and the Caribbean for both sexes, and Chile and Qatar for boys. Combined prevalence was also high in some countries in south Asia, such as India and Pakistan, where thinness remained prevalent despite having declined. In 2022, obesity in school-aged children and adolescents was more prevalent than thinness with a posterior probability of at least 0·80 among girls in 133 countries (67%) and boys in 125 countries (63%), whereas the converse was true in 35 countries (18%) and 42 countries (21%), respectively. In almost all countries for both adults and school-aged children and adolescents, the increases in double burden were driven by increases in obesity, and decreases in double burden by declining underweight or thinness. Interpretation The combined burden of underweight and obesity has increased in most countries, driven by an increase in obesity, while underweight and thinness remain prevalent in south Asia and parts of Africa. A healthy nutrition transition that enhances access to nutritious foods is needed to address the remaining burden of underweight while curbing and reversing the increase in obesit
