Contexto: Pesquisas sobre processos de aprendizagem humana em cursos de formação de professores têm sido discutidas. Esta pesquisa descreve o processo de formação da equipe do projeto "Coletivo de Aprendizagem em Geografia: estratégias autorregulatórias na formação de professores em Pelotas-RS". O projeto é focado em cinco ações: estratégias de aprendizagem dos estudantes de Licenciatura em Geografia, mapeamento das necessidades do curso e oficinas de intervenção. A metodologia inclui análise de documentos, observações, entrevistas e questionários aos estudantes. Oficinas serão planejadas e implementadas para promover a autorregulação da aprendizagem. Os resultados dessa pesquisa visam melhorar a formação de professores de Geografia e a prática educativa na área.

Orbital Compartment Syndrome (OCS) represents a critical medical emergency characterized by heightened orbital pressure, jeopardizing blood flow and posing a risk to the optic nerve. Often stemming from surgical procedures such as craniotomies for arachnoid cyst resection, OCS necessitates swift diagnosis and intervention. We report the case of a 77-year-old female in São Paulo, Brazil, who underwent left pterional craniotomy for arachnoid cyst resection. Postoperatively, she manifested reduced visual acuity in the left eye, restricted ocular movement, and peripalpebral hematoma indicative of orbital compression syndrome. Computed tomography scans confirmed pneumocephalus and pneumo-orbital complications, prompting an immediate diagnosis of OCS. Immediate interventions, including lateral canthotomy and cantholysis, were employed, resulting in successful decompression and substantial symptom improvement within a 10-day period. This case underscores the significance of preoperative imaging, prompt diagnostic measures, and collaborative postoperative care in managing orbital complications following neurosurgery.

Background: The relationship between superinfection by multidrug-resistant Gram-negative bacteria and mortality among SARS-CoV-2 hospitalized patients is still unclear. Carbapenem-resistant Acinetobacter baumannii and carbapenemase-producing Enterobacterales are among the most frequently isolated species when it comes to hospital-acquired superinfections among SARS-CoV-2 patients. Methods: Herein, a retrospective study was carried out using data from adult patients hospitalized for COVID-19. The interaction between in-hospital mortality and rectal carriage and superinfection by carbapenemase-producing Enterobacterales and/or carbapenem-resistant Acinetobacter baumannii was assessed. Results: The incidence of KPC-producing Klebsiella pneumoniae and/or carbapenem-resistant Acinetobacter baumannii rectal carriage was 30%. Bloodstream infection and/or pneumonia due to KPC-producing Klebsiella pneumoniae and/or carbapenem-resistant Acinetobacter baumannii occurred in 20% of patients. A higher Charlson comorbidity index (OR 1.41, 95% CI 1.24–1.59), being submitted to invasive mechanical ventilation/ECMO ≥ 96 h (OR 6.34, 95% CI 3.18–12.62), being treated with systemic corticosteroids (OR 4.67, 95% CI 2.43–9.05) and having lymphopenia at the time of admission (OR 0.54, 95% CI 0.40–0.72) were the features most strongly associated with in-hospital mortality. Conclusions: Although KPC-producing Klebsiella pneumoniae and/or carbapenem-resistant Acinetobacter baumannii rectal carriage, and/or bloodstream infection/pneumonia were diagnosed in a remarkable percentage of COVID-19 patients, their impact on in-hospital mortality was not significant. Further studies are needed to assess the burden of antimicrobial resistance as a legacy of COVID-19 in order to identify future prevention opportunities.

Background: Rheumatic heart disease (RHD) is the most serious manifestation of rheumatic fever, which may also affect the brain. The current study assessed the prevalence of neuropsychiatric manifestations in patients with RHD, including clinical features associated with basal ganglia motor dysfunction (BGMD). Methods: We conducted neurologic and psychiatric assessments in consecutive patients with RHD referred to a tertiary center for heart valve diseases. Echocardiography was performed to assess the pattern of valvular involvement and RHD severity. Validated questionnaires for the evaluation of cognition, depression, anxiety, and obsessive-compulsive symptoms (OCS) were applied. BGMD was clinically defined by the presence of hyperkinetic movement disorders. Results: Fifty patients with age of 43.2 ± 10.8 years, 84% female, were included. Mitral valve was affected in 47 patients (94%), and 21 of them (42%) also had aortic valve involvement. Chorea (22%), chronic tics (18%), OCS (48%), major depression (34%), generalized anxiety disorder (54%), cognitive complaints (66%), migraine (52%) and seizures (18%) were frequently reported. The factors associated with BGMD were age (p = 0.018), major depression (p = 0.013), and Yale-Brown Obsessive Compulsive (Y-BOCS) score (p = 0.011). The severity of heart disease was not associated with BGMD. Conclusions: Neuropsychiatric manifestations are frequent in RHD patients, which may persist up to three decades after acute rheumatic fever. Age, major depression and severity of OCS were independently associated with BGMD. These manifestations deserve a close attention of clinicians and researchers dealing with adult patients with RHD.

Orbital lymphomas are rare conditions, and most non-Hodgkin's lymphomas of the orbit are extranodal lymphomas of B cells of the marginal zone of the mucosa-associated lymphoid tissue type (MALT). In this report, we describe a case of MALT-type marginal zone B lymphoma in the orbital region. A female patient, 45 years old, searched for ophthalmological care, complaining, for 15 years, of low visual acuity (VA) associated with nonpulsatile bilateral proptosis, VA of 20/30 in the right eye and 20/40 in the left eye, without other changes. Magnetic resonance imaging of the brain and orbits showed solid expansive lesions in both orbital spaces, with biopsy and immunohistochemical study of the left orbit, showing lymphoproliferative syndrome, favoring B lymphoma of the MALT-type marginal zone. Thus, in view of the nonspecific initial presentation of MALT lymphoma, the use of imaging tests, as well as microsurgical biopsy, is essential for early diagnosis and surgical planning and constitutes the gold standard for adequate diagnostic elucidation.
