Resumen
Se desarrolló una nueva herramienta de evaluación de cognición social para adultos mayores brasileños, que mostró buena comprensión pero requirió mejoras en la claridad. La herramienta mostró un mejor rendimiento en tareas cognitivas que en tareas de faux-pas.
Área de la Ciencia:
- Gerontology; Neuropsychology; Cognitive Science
Sus antecedentes:
- Social cognition involves interpreting social and emotional cues for appropriate responses.
- A significant gap exists in Brazil for social cognition assessment tools tailored to older adults.
- Existing tools often lack cultural and demographic relevance for the Brazilian elderly population.
Objetivo del estudio:
- To develop and adapt a social cognition assessment tool specifically for Brazilian older adults.
- To gather content validity evidence through expert review and quantitative measures (CVI).
- To conduct a pilot study to assess the instrument's feasibility and initial performance in the target population.
Principales métodos:
- Instrument development based on Theory of Mind (ToM) tasks: False Belief, Strange Stories, and Faux-Pas.
- Expert review by psychologists, neuropsychologists, and geriatricians to evaluate comprehensiveness, clarity, and relevance.
- Pilot testing with 10 older adults (mean age 67.9 years) to evaluate comprehension and identify necessary modifications.
Principales resultados:
- A preliminary 12-subtest tool assessing false beliefs, pragmatic inference, and faux-pas was created.
- High inter-rater agreement among experts (0.66-1.0), with most tasks exceeding 80% agreement.
- Pilot participants understood most tasks, but some items needed refinement; better performance on cognitive tasks (false belief, Strange Stories) than affective-cognitive tasks (faux-pas).
Conclusiones:
- The developed instrument is tailored for Brazilian older adults, though modifications enhanced clarity and comprehension.
- Further standardization and norming with a larger, diverse sample of older adults (with and without clinical syndromes) are planned.
- This tool holds potential for advancing social cognition research and clinical practice in Brazilian gerontology.

520
Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Heart failure (HF) manifests primarily as dyspnea, fatigue, and fluid retention, resulting in peripheral and pulmonary edema. Symptoms may vary depending on which ventricle is more affected, left or right.Left-Sided Heart FailureAlso known as left ventricular failure, this condition results from the left ventricle's inability to fill or eject sufficient blood into the systemic circulation. It leads to pulmonary congestion, which occurs when the left ventricle fails to eject blood effectively...

437
Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...
