Este artigo investiga as atitudes ambientais de 183 estudantes do ensino médio de três escolas situadas nas proximidades do Parque Nacional Montanhas do Tumucumaque (PNMT), no Brasil. A análise se concentra em atitudes sobre ambientalistas, práticas de caça e interação com ambientes tidos como naturais, observando variações por gênero, série e escola. Os resultados indicam que a proximidade ao PNMT não corresponde necessariamente a um maior conhecimento ou envolvimento com ambientalistas, com apenas cerca de metade da amostra mostrando interesse por questões ambientais. Adicionalmente, a maioria expressou satisfação ao interagir com ambientes tidos como naturais. Foram observadas diferenças estatísticas significativas em alguns itens do questionário aplicado, como o maior interesse por questões ambientais na 3ª série do ensino médio e um maior apoio à caça entre o gênero masculino. Com base nestes resultados, recomenda-se a implementação de práticas educacionais que estimulem a curiosidade e o diálogo com ambientalistas, e que promovam maior interação dos alunos com os ambientes tidos como naturais em atividades práticas, para melhor integrar a educação às realidades ambientais locais.

Training novice students in a scientific field requires teaching conditions that allow them to interact with parameters that regulate the pertinence of disciplinary practices. With the purpose of providing empirical evidence, the present study aimed to assess the effect of varying the reading material on writing skills of college students. A pretest-post test experimental design with a control group was employed, involving 30 biology students assigned to three different conditions involving the exposure to reading materials and task resolution, subsequently, they wrote a text and a hypothetical experimental proposal. The results indicate correspondence between writing performances and the condition they were exposed to. The possibilities of generating didactic strategies related to the science of biology are discussed.

Introduction: For the improvement of health in the elderly population, innovative technologies such as intersectorality are needed. Objective: To describe the need for the application of intersectorality as a technology in the treatment of older adults. Methods: A narrative review was conducted between December 2023 and August 2024, through the Scielo, Medline databases, and the Google Scholar search engine, using keywords in Spanish. Around 1320 documents were recovered, including books, theses, and scientific articles, from which X most relevant to the study were selected. The selected studies were published in open access journals and high-impact books or articles on the topic, in Spanish or English. Results: Intersectoriality as a technology is based on the application of scientific knowledge to the solution of practical problems through a culture that provides methods to interact with the physical-social environment and improve living conditions. Intersectoriality in the treatment of older adults is an essential way to improve oral health and the needs for dental services that older adults may have, as a tool for social and community health work. Conclusions: The impact of aging on society, health and dental services, and the growing demands for care of the population over 60 years of age due to the characteristics of their age, show the need to apply intersectoriality as a guarantee of greater health and well-being.

Introduction: Rasmussen's encephalitis is a rare progressive neurological disease of unknown etiology. It is characterized by frequent, difficult-to-control polymorphic epileptic seizures, neurocognitive impairment, and radiological evidence of cerebral hemiatrophy, with onset in childhood and poor prognosis. Objective: To document the clinical history of a patient with atypical onset and progression of Rasmussen's encephalitis. Clinical case: A 19-year-old female, whose initial manifestation was behavioral disorder. Three months later, she presented progressive left hemiparesis and focal disperceptive seizures with motor symptoms, some of which could evolve into bilateral tonic clonic. Progressive cerebral hemiatrophy was observed on cranial magnetic resonance imaging. A brain biopsy was performed, which showed severe gliosis with predominance of gemastocytic astrocytes, scarce presence of retracted neurons with pyknotic nuclei, evidence of severe chronic neuronal damage, abundant microglia and perivascular inflammation of T lymphocytes, diagnosing Rasmussen's encephalitis. Conclusions: Rasmussen's encephalitis is a rare but devastating disease. Early diagnosis and treatment are key in the evolution of patients with and increase the chances of reintegration into social life.

Introduction: In order to improve the quality of health services, governments develop a set of public policies, for which tools have been developed to classify patient flows. Objective: To propose an assistive technology for the correct selection of patient flow modeling approaches. Methods: The research paradigm is qualitative, based on a bibliographic review in the PubMed and SCOPUS databases, and the Google Scholar search engine; carried out during the period 2004-2024. The validation was carried out using expert criteria, with a pilot application in the General Surgery service of the Faustino Pérez Provincial Clinical Surgical Teaching Hospital. Presentation: A checklist was designed to support health managers according to the problems to be solved or analysis to be carried out in the service. For processing and interpretation, an instrument was designed to show the possible approaches to be used from the combination of variables. Conclusions: An assistive technology was designed for healthcare managers for the correct selection of patient flow modeling approaches and thus improve decision-making processes during the implementation process.

Introduction: Hypotalamic hamartomas are malformations originating in the tuber cibereum and inferior hypothalamus. They have a wide spectrum in their clinical and electroencephalographic presentation, so their diagnosis and treatment are a challenge. Objective: Describe the clinical evolution, the results of complementary examination and the response to treatment in a patient whit unusual evolution of hypothalamic hamartoma. Clinical Case: 43-year-old female patient who presented in early childhood with gelastic seizures, without neurodevelopmental or endocrinological problems. In adolescence, she begins with disconnection seizures and sporadic bilateral tonic-clonic seizures; temporal lobe epilepsy is diagnosed. Learning, behavior and social adaptation remained normal. She continued her university studies with excellent performance, at the age of 36 she was diagnosed with hypothalamic hamartoma. She is currently a successful professional, despite not being controlled with anti-seizure medication.  She received a gamma knife session without clinical or imaging changes. Conclusions: A case of hypothalamic hamartoma with unusual evolution is shown, she presents poor control of gelastic seizures that have evolved into status epilepticus, despite which it has a successful professional performance.

Introduction: The lack of blood pressure control motivates an adequate study of related epidemiological and psychosocial characteristics. Objective: To evaluate the influence of epidemiological and psychosocial characteristics on blood pressure control in hypertensive patients. Methods: Observational, analytical, cross-sectional study, developed in 2024, in a sample of 560 hypertensive patients. The review of medical records and the application of instruments allowed obtaining information that gave way to the variables studied. Descriptive and inferential statistics methods were applied, which made it possible to establish the association between the independent variables and blood pressure control. Medical ethics were respected. Results: 55% of patients had uncontrolled blood pressure, with a predominance of females (70.7%), and an average age of 53.7 ± 15.4 years. These variables, along with marital status, education, and cohabitation, were associated with blood pressure control (p< 0.05); 22.1% of patients had normal stress levels, while medium levels of trait and state anxiety predominated (52.1% in both cases), which were also associated with blood pressure control (p< 0.0001). Conclusions: The identified epidemiological and psychosocial characteristics were shown to be associated with the lack of blood pressure control. This will enable future studies to use these findings as a basis for crafting strategies aimed at reducing the prevalence of uncontrolled hypertensive patients.

Introduction: Hereditary spherocytosis is a prevalent congenital hemolytic erythrocyte membranopathy. Laboratory diagnosis is traditionally based on erythrocyte morphology, yet 20% of cases may lack visible spherocytes, leading to misdiagnosis. The Eosin-5'-maleimide binding assay has emerged as a reliable diagnostic method. Objective: Evaluate the effectiveness of Eosin-5'-maleimide binding assay in diagnosing hereditary spherocytosis in pediatrics with negative-direct-antiglobulin-test-hemolytic anemia. Methods: A cross-sectional study was conducted with 66 negative-direct-antiglobulin-test-hemolytic-anemic patients and 44 healthy controls. The percentage of spherocytes was scored from peripheral blood smear observation; the percentage of decreased mean fluorescent intensity from Eosin-5'-maleimide binding assay was used to determine red cell membrane protein deficiency, and hereditary spherocytosis was finally confirmed by gene sequencing as a gold standard. Results: Eosin-5'-maleimide binding assay demonstrated high sensitivity (93.33%), specificity (100%), and accuracy (97.3%) in detecting hereditary spherocytosis, with an optimal cut-off value of 47.83% decreased mean fluorescent intensity. Conclusion: The Eosin-5'-maleimide binding assay is a highly accurate diagnostic tool that outperforms traditional blood smear analysis. It is precious for detecting hereditary spherocytosis in patients with mild clinical manifestations or coexisting hemolytic disorders. This assay should be considered a frontline test for diagnosing hereditary spherocytosis in patients with hemolytic anemia.

Introduction: Peripheral arterial disease is caused by the presence of an obstruction in the arteries in the lower limbs. A series of factors that may influence the appearance and severity of this condition are described. Objective: To characterize patients over 50 years of age with a diagnosis of peripheral arterial disease of the lower limbs. Methods: A descriptive study was carried out in a series of 110 cases over 50 years of age with a diagnosis of peripheral arterial disease. The variables studied included the general characteristics of the subjects (age and sex), risk factors for the disease and its form of presentation; The data were obtained from the individual clinical histories of each patient. Results: Average age of 64.39 years, predominance of male patients (61.82%) and presence of between 2 and 3 risk factors for chronic peripheral arterial disease (60.91%). Male sex (61.82%), smoking (70.00%) and dyslipidemia (90.00%) were identified as predominant risk factors. In 65.45% of the patients, intermittent claudication was the clinical presentation of the disease. Conclusions: Being male, having several risk factors for the disease, and intermittent claudication as a presentation are frequently identified characteristics in patients treated with peripheral arterial disease of the lower limbs.
