<title>Abstract</title> <bold>Introduction:</bold> Unilateral pontine stroke can impair upper limb motor function due to damage in brainstem motor pathways. An emerging intervention approach proposes the combination of neuroplasticity-inducing techniques such as transcranial direct current stimulation (tDCS) with task-specific training exercises like robot-assisted therapy. <bold>Objective:</bold> To examine the effects of primary motor cortex dual-tDCS (excitatory ipsilesional and inhibitory contralesional) combined with collaborative robot-assisted therapy on hand/upper limb motor function and fatigue of a patient with unilateral chronic pontine stroke. <bold>Methodology:</bold> A 10-session protocol combining dual-tDCS with a collaborative robot-assisted upper limb exercises was employed. Outcome measures (assessed pre-intervention, mid-intervention, post-intervention, and 1-month follow-up) included hand/upper limb motor function (manual dexterity, hand grip strength, motor reaction time, shoulder flexion range of motion) and perceived physical and mental fatigue. A structured interview was conducted to capture the participant’s subjective perception of improvement. <bold>Results:</bold> The patient showed significant post-intervention improvements in manual dexterity, shoulder flexion range of motion, and hand grip strength, while also displaying reduction in physical fatigue. These results were largely retained after the 1-month follow-up period. The structured interview indicated that the patient reported greater participation in daily activities, with less perceived fatigue. <bold>Conclusion:</bold> The combination of dual-tDCS with robot-assisted therapy in a patient with unilateral chronic pontine stroke demonstrated positive effects on hand/upper limb motor function as well as on physical fatigue. This intervention protocol may be a useful and engaging complementary rehabilitation approach for several stroke subtypes.

As cirurgias de terceiros molares são procedimentos odontológicos invasivos que frequentemente demandam controle rigoroso da dor, estresse e ansiedade. Pacientes com disfunção temporomandibular (DTM) podem apresentar exacerbação de sintomas dolorosos durante e após o ato cirúrgico devido ao esforço isométrico e ao aumento da tensão emocional. Este estudo teve como objetivo relatar o uso do medicamento homeopático Hypericum perforatum 30CH no manejo da dor, estresse e ansiedade em paciente com DTM ativa submetida à exodontia prolongada dos elementos 28 e 38. Trata-se de relato de caso clínico aprovado por Comitê de Ética em Pesquisa, no qual a paciente, portadora de bruxismo noturno e alto nível de estresse, recebeu Hypericum perforatum 30CH dois dias antes e no pós-operatório imediato. Foram avaliados dor e ansiedade por meio da escala visual analógica (EVA) e observada a evolução clínica. A paciente apresentou controle satisfatório da ansiedade pré-operatória, dor leve intra e pós-operatória, ausência de agravamento dos sintomas de DTM e melhora da qualidade do sono. Conclui-se que o Hypericum perforatum 30CH pode ser uma alternativa terapêutica complementar segura e potencialmente eficaz para pacientes com DTM e ansiedade submetidos a cirurgias de terceiros molares, sendo recomendada a realização de estudos com maior amostra para validação desses achados.

Organizational process documentation is often fragmented, inconsistent, and frequently updated, creating challenges for effective information retrieval. In fast-paced environments like Android development, project leaders need quick access to accurate and clear process-related information. We propose a Retrieval-Augmented Generation (RAG)-based AI agent to improve the assertiveness and clarity of answers retrieved from evolving internal documentation. A case study was conducted at a global technology institute, integrating dense retrieval with a LLaMA-based model and embedding-based chunk retrieval from internal wikis. Using a set of 226 real-world queries, the agent achieved a Recall of 0.71, Precision of 0.18, and F1-Score of 0.28. Manual validation by 30 project leaders revealed a perceived accuracy of 82.4%, indicating effective support for clarity and relevance. The RAG agent improved information access and user satisfaction while reducing manual search effort. However, retrieval precision remains a limitation, suggesting future enhancements via hybrid retrieval strategies and feedback loops.

A peri-implantite é um dos maiores desafios da implantodontia contemporânea, caracterizada por inflamação associada à perda óssea marginal progressiva. O tratamento convencional, centrado no desbridamento mecânico, enfrenta limitações impostas pela morfologia das superfícies implantárias e pela resiliência do biofilme. Nesse cenário, terapias adjuvantes como lasers, terapia fotodinâmica antimicrobiana (aPDT) e concentrados plaquetários autólogos (PRP, PRF, CGF) têm sido investigadas para potencializar a descontaminação e favorecer a regeneração tecidual. Esta revisão integra evidências recentes sobre mecanismos de ação, resultados clínicos e inovações, discutindo vantagens, limitações e perspectivas de uso. Conclui-se que a combinação criteriosa de abordagens tecnológicas e biológicas, aliada ao rigor no controle do biofilme, pode aprimorar o manejo da peri-implantite e otimizar a regeneração óssea em implantodontia.

Este estudo analisa os condicionantes naturais na definição dos percursos coloniais rumo às regiões mineradoras do centro-sul do Brasil, com especial atenção aos Caminhos Velho e Novo, entre o litoral do Rio de Janeiro e as Minas Gerais. A pesquisa parte da hipótese de que fatores ambientais, em particular os rios e o regime de chuvas, exerceram influência significativa sobre as decisões logísticas e os traçados viários durante o período de consolidação da empresa aurífera. Para isso, foram mobilizadas fontes históricas diversas, como relatos de viajantes, cronistas e registros administrativos, em articulação com dados pluviométricos recentes (1976–2006), tratados como indicadores aproximados de padrões climáticos seculares. A análise dessas informações foi realizada com o apoio de ferramentas de geoprocessamento, que permitiram a espacialização dos dados e a comparação sistemática dos percursos. A fundamentação teórica inspira-se na noção de longa duração, proposta por Fernand Braudel, que reconhece a estabilidade relativa dos ritmos naturais na conformação histórica do território.

Objectives: This review explores the current evidence on how different massage modalities, either manual (MM) or using foam rolling (FR), with or without strength training, influence cardiovascular and autonomic function in healthy individuals. Methods: A search was performed in CINAHL, Cochrane Library, PubMed®, and SciELO databases on 14 April 2025. Results: Among the 5125 studies retrieved in the database search, 7 were selected for the present review. The included studies pointed to an improvement in hemodynamic and autonomic responses, characterized by reduced arterial stiffness and blood pressure and an increase in nitric oxide concentration and blood flow. These findings suggest that physical exercise prescribers should consider the hemodynamic and autonomic effects promoted by massage (MM or FR). Conclusions: A change in arterial compliance, followed by a hypotensive effect on systolic blood pressure, reinforces the role of physical activity as a non-pharmacological agent and highlights the need for inclusion in the different groups that need adjuvant help for blood pressure control.

Background: Warm-up strategies are essential for optimizing strength-training performance. Traditional warm-ups improve neuromuscular readiness, whereas post-activation potentiation (PAP) has been proposed to acutely enhance muscular output. This randomized crossover study compared the acute effects of traditional and PAP-based warm-ups on local muscular endurance (LME) during free weight back squats in resistance-trained men. Methods: Twelve trained males (age: 41.3 ± 5.7 years; one repetition maximum squat: 129.3 ± 14.3 kg) completed three randomized squat sessions: mobility with LME (M + LME), traditional warm-up with LME (T + LME), and PAP with LME (PAP + LME). The sessions were spaced 48 h apart. Outcomes included the number of repetitions, blood lactate concentration, time under tension (TUT), perceived exertion through OMNI Resistance Exercise Scale (OMNI-RES), and pain perception through visual analogue scale (VAS). One-way ANOVA and partial eta-squared (η2p) were used for statistical analyses. Results: PAP + LME significantly increased the number of repetitions (15.63 ± 3.66) compared to both M + LME (12.38 ± 3.89) and T + LME (13.63 ± 3.82; p < 0.0001). Blood lactate levels were significantly higher in PAP + LME (8.98 ± 3.87 mmol/L) compared to M + LME (5.08 ± 0.97 mmol/L; p = 0.01). TUT was significantly shorter in both the PAP + LME and T + LME groups than in the M + LME group (p < 0.05). VAS scores were higher after PAP + LME (8.50 ± 0.45) than after M + LME (6.50 ± 1.20; p = 0.02), while OMNI-RES scores did not differ significantly between the protocols. Conclusions: Both traditional and PAP-based warm-ups improved squat LME compared with mobility alone. PAP elicited greater repetition performance and metabolic stress but also increased discomfort. Warm-up selection should align with training goals, balancing performance benefits and perceived fatigue.

The study aimed to map the national scientific production about the role and practices of the school psychologist. To this end, an integrative review of the literature that addressed the topic before and after the enactment of Law No. 13,935/19 was carried out. The study followed the PRISMA protocol, a survey was carried out in 4 databases: BVS (Virtual Health Library), PubMed, SciELO and Lilacs. Sixteen published articles were identified, most of them with a qualitative approach. No articles were found that addressed the role and practices of the school psychologist after the publication of the law. The content analysis found 4 categories: 1- The different nomenclatures attributed to the psychologist who works in schools; 2- The lack of definition of the Role and practices of the school psychologist; 3- Training in Psychology courses and its emphases and Category 4- Clinical Psychology practiced in the educational context. The results indicate the need to conduct studies that address the law and the practices of the psychologist in educational institutions. It is necessary to demarcate and clarify the role and practices of the school psychologist, so that the professional can perform actions that are consistent with the demands of the school context. It is believed that the study can assist in the construction and implementation of public policies and in the production of knowledge and reflections on the role and practices of the school psychologist. It is urgent to train a Psychology professional with a critical stance, meaningful performance and awareness of their attributions, to expand and define School Psychology.
