NOTIFICAÇÕES DE ARTIGOS MÉDICOS DO ESTADO DO AMAZONAS NO ANO DE 2025: UM ESTUDO DESCRITIVO
OBJETIVO: Descrever as notificações de artigos médico-hospitalares registradas no estado do Amazonas em 2025 no Sistema Nacional de Notificações em Vigilância Sanitária (NOTIVISA), segundo município, tipo de notificante e nome técnico do produto. MÉTODO: Estudo observacional, descritivo e retrospectivo, quantitativo, com dados secundários do Portal de Dados Abertos da Anvisa (01/01/2025 a 31/12/2025). Análise por estatística descritiva no programa R (v. 4.4.0), com frequências absolutas e relativas. RESULTADOS: O Amazonas registrou 205 notificações em 2025: 178 (86,8%) de artigos médico-hospitalares, 23 (11,2%) de equipamentos médico-hospitalares e 4 (2,0%) de kits para diagnóstico in vitro. As notificações de artigos representaram 0,85% do total nacional (N=20.864), ao passo que o estado concentra 1,9% da população brasileira. Houve forte centralização espacial: 99,4% (n=177) dos registros procederam de Manaus. Predominaram hospitais e hospitais sentinela (74,7%). O nome técnico do produto não foi informado em 25,3% (n=45) das notificações de artigos. CONCLUSÃO: O volume relativo de notificações foi reduzido em relação ao total nacional, concentrado na capital, com incompletude do nome técnico em cerca de um quarto dos registros. Por se tratar de dados secundários, não é possível estimar a magnitude da subnotificação; é necessário investigar as barreiras ao registro.

FORMAÇÃO DE JOVENS EM CONTEXTOS PERIFÉRICOS: EDUCAÇÃO EMANCIPATÓRIA, ECONOMIA SOLIDÁRIA E DESENVOLVIMENTO TERRITORIAL
A juventude em territórios periféricos enfrenta desemprego, informalidade e desigualdades que limitam sua inserção produtiva e participação social. Objetivo: Analisar como processos formativos articulados à educação emancipatória, à liderança comunitária, ao empreendedorismo e à economia solidária podem contribuir para o protagonismo juvenil e o desenvolvimento territorial. Metodologia: Realizou-se uma revisão narrativa da literatura, apoiada em levantamento bibliográfico exploratório na base SciELO, abrangendo publicações de 2018 a 2026. Utilizaram-se os descritores “Educação Emancipatória”, “Juventude”, “Empreendedorismo” e “Economia Solidária”, isoladamente e em combinações, em diálogo com os referenciais discutidos no estudo. Resultados: a busca evidenciou limitada articulação entre os eixos investigados na produção localizada. A análise sugere que a formação técnica associada à educação crítica, à participação comunitária e às redes de cooperação pode favorecer a autonomia, a autogestão e a formação de lideranças juvenis. Em contraste, o empreendedorismo individual por necessidade, quando desvinculado de apoio institucional e organização coletiva, pode reproduzir a precariedade econômica. Propõe-se uma estrutura processual de formação que integra diagnóstico territorial, desenvolvimento de competências e projeto comunitário aplicado. Conclusão: a formação juvenil pode ampliar seu potencial transformador quando ultrapassa a preparação exclusiva para o mercado de trabalho e se articula a políticas públicas, redes comunitárias e iniciativas solidárias. São necessárias pesquisas empíricas e longitudinais para avaliar os efeitos dessas estratégias nos territórios.

Complement system and glial activation biomarkers in cerebrospinal fluid: correlation with cognitive decline in Alzheimer’s disease
Introduction: Traditionally viewed through a neurocentric lens, Alzheimer's Disease (AD) has been reinterpreted considering the neuroglial unit. Microglial activation and the conversion of astrocytes to the A1 neurotoxic phenotype result in ionic imbalance and neuronal electrical silencing, culminating in synaptic opsonization via the complement system (CS). Objective: To identify the correlation between the levels of complement system biomarkers (complement component 1q and complement component 3) and glial activation biomarkers in cerebrospinal fluid (glial fibrillary acidic protein, chitinase-3-like protein 1, and soluble triggering receptor expressed on myeloid cells 2) and cognitive performance in Alzheimer’s disease. Methodology: Integrative literature review with a mechanistic approach of articles published between 2016 and 2026, that related complement system and glial activation biomarkers in the cerebrospinal fluid (CSF) to cognitive decline in AD. Results: Complement protein levels were associated with impoverished cognitive performance and neurodegeneration markers, while soluble fragment released in triggering receptor expressed on myeloid cells 2 (sTREM2) correlated with tau pathology markers. Glial fibrillary acidic protein (GFAP) and chitinase 3–like protein (YKL-40) showed early elevation in Aβ-positive individuals and were associated with cognitive decline and changes in cortical thickness. Conclusion: Glial activation and complement system biomarkers may act as potential indicators of the pathophysiological dynamics of Alzheimer's disease across its clinical spectrum, reflecting early changes associated with amyloid deposition and the progression of neurodegeneration.

Visivel as an epistemological infrastructure for territorial social assistance: Humanized registration, georeferenced evidence, and responsible predictive governance
This article aims to examine Visivel as an epistemological infrastructure for territorial social assistance aimed at people experiencing homelessness. Rather than treating the platform only as administrative software, the study analyzes how it produces, protects, and organizes public knowledge about a population whose presence is often fragmented across streets, services, reports, and institutional records. The methodological corpus combines the public interface available at the Visivel web system, the implementation guide, and the technical resource report prepared for public managers. The analysis identifies four epistemic operations: humanized identification, georeferenced territorialization, intersectoral interpretation, and responsible predictive governance. The article argues that Visivel's central contribution lies in converting situated encounters and citizen reports into protected traces that can support planning, outreach routes, service referrals, monitoring, and accountability under SUAS, the National Policy for the Homeless Population and the LGPD. Its predictive layer is interpreted as a decision-support mechanism, not as an automated decision-maker, because institutional responsibility remains with human managers and social workers. The proposed model contributes to debates on data-driven social policy by showing that technical sophistication in vulnerable contexts depends on privacy, territorial accountability, and epistemic humility.

Physical Activity and Healthy Aging: Functional, Cognitive, and Sleep Predictors Associated with Fall Risk in Older Adults
Falls among older adults are a major public health concern due to their association with functional decline and increased healthcare utilization. This study investigated factors associated with fall occurrence by comparing older adults enrolled in a community-based physical activity program with sedentary older adults. This observational cross-sectional study included 67 older adults: 35 participants enrolled in the Niterói 60 Up program (G60UP; 68 ± 4 years) and 32 sedentary older adults in a sedentary comparison group (SCG; 70 ± 7 years). Assessments included anthropometric measurements, medication use, Timed Up and Go (TUG), Tinetti Performance-Oriented Mobility Assessment, Mini-Mental State Examination (MMSE), Pittsburgh Sleep Quality Index (PSQI), and orthostatic testing. Compared with the SCG, G60UP participants reported fewer falls during the previous year (0.26 ± 0.51 vs. 0.78 ± 0.83; p = 0.005), higher Tinetti scores (24.51 ± 2.54 vs. 18.28 ± 5.94; p < 0.001), shorter TUG times (8.66 ± 1.63 vs. 13.00 ± 4.31; p < 0.001), higher MMSE scores, better sleep quality (lower PSQI scores), and lower blood pressure and abdominal adiposity indicators. In the total sample, fall occurrence was associated with lower Tinetti scores (ρ = −0.416; p < 0.001), longer TUG times (ρ = 0.321; p = 0.008), older age (ρ = 0.328; p = 0.007), higher Conicity Index (ρ = 0.281; p = 0.021), and poorer sleep quality (ρ = 0.243; p = 0.047). No variable remained independently associated with falls in the exploratory multivariable logistic regression model. Participants enrolled in the 60 Up program presented more favorable functional, cognitive, sleep-related, and health-related profiles than those in the SCG. Due to the cross-sectional design, these findings should be interpreted as associations rather than causal relationships.

Development and evaluation of a deep learning model for dental image classification
Dental image analysis can be affected by factors such as lighting, framing, image quality, and visual similarity among different oral conditions. This study aims to present the development and evaluation of OdontoAI, a minimum viable product designed for the automatic classification of dental images into six categories: calculus, caries, gingivitis, hypodontia, mouth ulcer, and tooth discoloration. The project used the public dataset Oral Diseases (Kaggle), submitted to a rigorous curation process including duplicate removal by MD5 hash, grouping by perceptual hash (pHash), and controlled partitioning at a 70/15/15% ratio. The final dataset contained 3,507 images. Classification was performed using a ResNet-50 architecture adapted through two-phase transfer learning. On the test set (524 images), the model achieved an accuracy of 96.18% and a macro F1-score of 90.78%. The best results were observed for gingivitis and hypodontia; caries presented a recall of 64.29%, reflecting difficulties associated with class imbalance and visual similarity between categories. Qualitative Grad-CAM analysis indicated activations in relevant dental regions, treated as a complementary resource rather than a diagnostic tool. The study demonstrates that rigorous curation protocols directly affect reported metrics, making direct comparisons with studies that do not control for data leakage across partitions invalid.
