Validating Artificial Intelligence before the Bedside: ChatGPT-4 vs Mini in Guideline-Based Hypertension Content

Cláudio Tinoco Mesquita et al. Fernanda Azevedo Silva Ana Beatriz Costa do Couto

The rapid integration of artificial intelligence (AI) into medical practice is a reality. From clinical decision support and study design to chatbot tools and the production of educational materials, large language models (LLMs) are increasingly used in daily practice. In this context, studies like the study of Ataídes et al., evaluating the performance of LLM-based materials, are crucial.

Hypertension is one of the leading causes of premature death; therefore, the World Health Organization (WHO) invests in prevention campaigns. It is a disease that affects multiple organs, causing a major impact on the entire body. The condition is defined by a systolic blood pressure (BP) of 140 mmHg or higher, or a diastolic BP of 90 mmHg, according to Brazilian Society of Cardiology guidelines. The number of individuals diagnosed with hypertension increases each year, and studies indicate that the population’s eating habits are characterized by high consumption of ultra-processed foods.

Validation of the Portuguese version of the Minnesota Living with Heart Failure Questionnaire

Vitor Oliveira Carvalho et al. Guilherme Veiga Guimarães Dirceu Carrara Fernando Bacal Edimar Alcides Bocchi

BACKGROUND: The Minnesota Living with Heart Failure Questionnaire (MLHFQ) is an important measurement instrument for assessing the quality of life of heart failure patients. Despite being largely used within our context, the questionnaire had not yet been translated and validated into the Portuguese language. OBJECTIVE: Of this study was to translate and validate the Portuguese version of the MLHFQ for use in heart failure patients. METHODS: Forty patients with heart failure (30 men, LVEF 30±6%, 55% ischemic etiology, classified as NYHA I to III), clinically stable and on optimized drug therapy underwent maximal cardiopulmonary stress testing to assess their physical capacity. Right after the test, the MLHFQ duly translated into Portuguese was administered by the same investigator. The NYHA functional classification was provided by the medical team. RESULTS: The Portuguese version of the MLHFQ had the same structure and metrics of the original version. There was no difficulty in the administration of the questionnaire or in the patient’s understanding of the questions. The Portuguese version of the MLHFQ was consistent with peak VO2, duration of the cardiopulmonary test, and NYHA functional classification. There was no difference in the score mean for the questionnaire between the group of patients with ischemic etiology and the group with non-ischemic etiology. CONCLUSION: The Portuguese version of the MLHFQ proposed in this study proved to be valid for heart failure patients, and constitutes a new and important instrument for assessing quality of life.

Assessment of the DIXTAL DX-2710 Automated Oscillometric Device for Blood Pressure Measurement with the Validation Protocols of the British Hypertension Society (BHS) and the Association for the Advancement of Medical Instrumentation (AAMI)

Gisele M. P. Mano et al. Viviane F. Souza Angela M. G. Pierin Josiane C. Lima … Edna C. Ignes Kátia C. Ortega Décio Mion Jr.

OBJECTIVE: To assess the Dixtal DX2710 automated oscillometric device used for blood pressure measurement according to the protocols of the BHS and the AAMI. METHODS: Three blood pressure measurements were taken in 94 patients (53 females 15 to 80 years). The measurements were taken randomly by 2 observers trained to measure blood pressure with a mercury column device connected with an automated device. The device was classified according to the protocols of the BHS and AAMI. RESULT: The mean of blood pressure levels obtained by the observers was 148±38/93±25 mmHg and that obtained with the device was 148±37/89±26 mmHg. Considering the differences between the measurements obtained by the observer and those obtained with the automated device according to the criteria of the BHS, the following classification was adopted: “A” for systolic pressure (69% of the differences < 5; 90% < 10; and 97% < 15 mmHg); and "B" for diastolic pressure (63% of the differences < 5; 83% < 10; and 93% < 15 mmHg). The mean and standard deviation of the differences were 0±6.27 mmHg for systolic pressure and 3.82±6.21 mmHg for diastolic pressure. CONCLUSION: The Dixtal DX2710 device was approved according to the international recommendations.
