Electronic inspiratory muscle training in hospitalized patients: a systematic review
Introduction: Respiratory muscle weakness is common in hospitalized patients, particularly in intensive care units, and is associated with worse clinical outcomes, such as prolonged mechanical ventilation and length of hospital stay. Inspiratory muscle training is a rehabilitation strategy performed using mechanical or electronic devices, the latter offering greater capacity for monitoring and load adjustment. Objective: To critically analyze the evidence on the effectiveness of inspiratory muscle training using electronic devices compared with control conditions (sham training, T-piece/spontaneous breathing, or usual care/conventional physiotherapy) in hospitalized patients. Methods: We searched MEDLINE (via PubMed), Embase, LILACS, and PEDro from inception to June 2026, without date or language limits, for randomized controlled trials in hospitalized patients. Risk of bias was assessed with RoB 2 and certainty of evidence (CoE) with GRADE; random-effects meta-analyses (DerSimonian--Laird) were performed. Results: Eight randomized controlled trials (458 participants) were included. Maximal inspiratory pressure may increase after the intervention (MD 6.89 cmH₂O; 95%CI 0.11 to 13.67; low CoE). The evidence was very uncertain about shorter mechanical ventilation weaning time in the intervention group (MD −5.69 days; 95%CI −8.84 to −2.55; very low CoE). Weaning success did not differ between groups (RR 1.27; 95%CI 0.79 to 2.05; very low CoE). Conclusion: Electronic inspiratory muscle training may improve inspiratory muscle strength and reduce mechanical ventilation weaning time in hospitalized patients. The certainty of evidence ranged from low to very low; the findings should be interpreted with caution. PROSPERO CRD42024539420.

Mapeamento das Tecnologias de Saúde para o Tratamento de Doenças Negligenciadas em Crianças no SUS
Introdução (com objetivo): As Doenças Tropicais Negligenciadas (DTN) afetam principalmente populações vulneráveis, com alta prevalência em países em desenvolvimento, incluindo o Brasil, onde doenças como hanseníase, leishmanioses e doença de Chagas representam importante problema de saúde pública. Na população pediátrica, a exposição precoce a condições ambientais desfavoráveis aumenta a incidência de infecções como malária e doença de Chagas, elevando a morbidade e a demanda por serviços de saúde. Nesse cenário, a Avaliação de Tecnologias em Saúde (ATS) é essencial para orientar a adoção de intervenções eficazes e acessíveis no Sistema Único de Saúde (SUS), contribuindo para a redução da carga dessas doenças e a melhoria da qualidade de vida infantil. Mapear as recomendações de tecnologias sobre DTN para a população pediátrica disponíveis no Sistema Único de Saúde. Material e Método: Trata-se de uma análise documental, descritiva e retrospectiva dos relatórios de recomendação referentes a medicamentos, produtos e procedimentos de DTN em crianças e adolescentes, publicados no sítio eletrônico da Conitec entre 2015 e janeiro de 2026. A identificação e seleção dos relatórios foi realizada em abril por um pesquisador, sendo posteriormente revisada por um segundo pesquisador. Os dados foram extraídos dos relatórios de recomendação disponíveis em planilha de Excel.O protocolo foi publicado no Open Science Framework (doi: 10.17605/OSF.IO/2XPQ5). Resultados: Durante o período analisado foram identificadas 23 tecnologias, das quais 16 (69,57%) são medicamentos, 6 (26,09%) procedimentos e 1 (4,35%) equipamento. Destas, 17 tecnologias (73,91%) tiveram a decisão final de incorporação no SUS, enquanto 5 (21,73%) receberam a decisão de ampliação de uso. Apenas 1 tecnologia (4,35%) foi excluída após a análise. A maioria das tecnologias (95,6%) foi destinada à população pediátrica em conjunto com a população em geral, com exceção de uma tecnologia que é exclusiva para crianças menores de 10 anos. Quanto ao demandante dessas tecnologias, a grande parte (91,3%) foi originada de departamentos ou secretarias do Ministério da Saúde, enquanto 1 tecnologia (4,35%) teve origem na indústria farmacêutica e outra (4,35%) foi demandada por sociedade médica. As doenças mais tratadas pelas tecnologias avaliadas foram a hanseníase, a tuberculose e a malária, que são algumas das principais doenças tropicais negligenciadas que afetam a população brasileira. Em relação à síntese de evidências, apenas 12 relatórios (52,17%) relataram análise de risco de viés ou avaliação da certeza da evidência pela metodologia GRADE. No que se refere à avaliação econômica em saúde (AES), 14 relatórios (60,87%) realizaram algum tipo de análise econômica. Desses, sendo a Análise de Custo-Efetividade a mais prevalente (10 relatórios, 71,43%). Conclusões: A análise mostra um avanço na incorporação de tecnologias eficazes no SUS para o tratamento de doenças tropicais negligenciadas. A maioria das tecnologias foi demandada pelo Ministério da Saúde, destacando a prioridade governamental no acesso ao tratamento. Essas ações têm o potencial de melhorar a saúde infantil, especialmente em populações vulneráveis. Assim, busca-se reduzir a carga dessas doenças e promover um atendimento mais acessível.

Methodological Characteristics in Economic Evaluations of Health Technology Assessment Reports Submitted for Drug Reimbursement in Brazilian Public Health
Objectives: To characterize methodological aspects and the quality reporting of economic evaluation in HTA reports of drugs submitted to the Brazilian public health system. Methods: An electronic search for HTA reports focusing on drug incorporation into the public health system published between 2020 and June 2024 was conducted in the Conitec database. The study selection and data extraction were performed to obtain bibliographic data, base case characteristics, and methodological features. Furthermore, the quality reporting of economic evaluation was verified by the Consolidated Health Economic Evaluation Reporting Standards 2022 (CHEERS 2022). Descriptive statistics summarize the data extracted from the documents. Results: We included 188 economic evaluations of HTA reports about drug reimbursement; the great majority submitted to private companies or public institutions. Most economic evaluations adopted cost‐utility or cost‐effectiveness analysis using a comparator in the public system. Economic evaluation studies presented frequent inconsistent reports of cost and health outcomes and in the deterministic and probabilistic sensitivity analyses. Markov, decision tree, and partitioned survival model were the main mathematical models applied. Cost‐effectiveness analysis mainly adopted QALY or QALY plus life‐years gained as health outcomes, but there was a lack of clarity in the methods to incorporate health utilities in the cost‐utility analysis. Finally, we identified that the quality reporting of economic evaluation needs to be improved. Conclusion: The methods and reporting quality of economic evaluations submitted to Conitec exhibit heterogeneity characteristics. Strengthening and standardizing guidance for preparing health economic evaluations is needed to ensure greater consistency, transparency, and decision‐making reliability.

Influência da albumina e do ângulo de fase na sobrevida de pacientes com doença renal crônica em hemodiálise: um estudo prospectivo
Resumo Introdução: A hemodiálise (HD) prolonga a sobrevida de pacientes com doença renal crônica (DRC) em estágio V, mas a mortalidade permanece elevada devido à desnutrição e à inflamação. Este estudo teve como objetivo investigar se baixos níveis de albumina e um ângulo de fase (AF) reduzido predizem maior mortalidade em pacientes em HD. Métodos: Este estudo de coorte prospectivo acompanhou 82 pacientes em HD por 36 meses. Marcadores biológicos, incluindo albumina e indicadores de estresse oxidativo, foram mensurados antes e após uma única sessão de HD no momento da inclusão no estudo (tempo zero). O AF foi determinado por análise de bioimpedância (BIA). Curvas de sobrevida de Kaplan-Meier e análises de regressão de Cox foram realizadas para avaliar a associação entre albumina, AF e mortalidade. Resultados: Pacientes com AF < 4 apresentaram sobrevida média de 11,6 meses, em comparação a 27,0 meses entre aqueles com AF ≥ 4 (HR = 5,66; IC 95%: 2,44–13,12). De forma semelhante, pacientes com albumina < 3,9 g/dL apresentaram taxas de sobrevida significativamente mais baixas aos 6, 12 e 36 meses em comparação àqueles com albumina ≥ 3,9 g/dL (HR = 4,39; IC 95%: 1,81–10,63). Conclusão: Baixos níveis de albumina e AF reduzido são fortes preditores de mortalidade em pacientes em HD. O monitoramento de rotina e intervenções direcionadas para melhorar esses marcadores podem contribuir para melhores desfechos de sobrevida.

CD4+ differentiated T regulatory cells is modified by physical fitness and visceral adipose tissue in young adults—A cross‐sectional study
Central adiposity and poor cardiorespiratory fitness are modifiable risk factors for various diseases. This study investigated their impact on CD4+ differentiated T regulatory (Treg) cell responses. Thirty‐eight young adults were classified into high cardiorespiratory fitness/low visceral adipose tissue (High V̇O2–Low VAT, n = 20) and low cardiorespiratory fitness/high VAT (Low V̇O2–High VAT, n = 18). Body composition was assessed using DXA and ultrasound, while cardiorespiratory fitness and physical activity were measured via treadmill testing and accelerometry. CD4+ cells were cultured in Treg differentiation medium with 2 ng/mL TGF‐β, with or without 100 nM rapamycin or 50 nM Torin‐1, for 96 h. Differentiated Treg from Low V̇O2–High VAT participants exhibited no significant changes in IL‐10 or IL‐6 production with rapamycin or Torin‐1. Conversely, differentiated Treg from High V̇O2–Low VAT participants showed significantly lower IL‐10 production with rapamycin (p < 0.001, adjusted p < 0.001) and Torin‐1 (p < 0.001, adjusted p < 0.001). These findings indicate that low cardiorespiratory fitness and high VAT contribute to an altered inflammatory response, influencing peripheral blood mononuclear cell immunophenotypes and exhaustion markers. Furthermore, mTORC1 and mTORC2 inhibition modulate cytokine production, emphasizing the role of metabolic status in immune regulation.
