RESUMEN
BACKGROUND: The classification of heart failure (HF) by phenotypes has a great relevance in clinical practice. OBJECTIVE: The study aimed to analyze the prevalence, clinical characteristics, and outcomes between HF phenotypes in the primary care setting. METHODS: This is an analysis of a cohort study including 560 individuals, aged ≥ 45 years, who were randomly selected in a primary care program. All participants underwent clinical evaluations, b-type natriuretic peptide (BNP) measurements, electrocardiogram, and echocardiography in a single day. HF with left ventricular ejection fraction (LVEF) < 40% was classified as HF with reduced ejection fraction (HFrEF), LVEF 40% to 49% as HF with mid-range ejection fraction (HFmrEF) and LVEF ≥ 50% as HF with preserved ejection fraction (HFpEF). After 5 years, the patients were reassessed as to the occurrence of the composite outcome of death from any cause or hospitalization for cardiovascular disease. RESULTS: Of the 560 patients included, 51 patients had HF (9.1%), 11 of whom had HFrEF (21.6%), 10 had HFmrEF (19.6%) and 30 had HFpEF (58.8%). HFmrEF was similar to HFpEF in BNP levels (p < 0.001), left ventricular mass index (p = 0.037), and left atrial volume index (p < 0.001). The HFmrEF phenotype was similar to HFrEF regarding coronary artery disease (p = 0.009). After 5 years, patients with HFmrEF had a better prognosis when compared to patients with HFpEF and HFrEF (p < 0.001). CONCLUSION: The prevalence of ICFEI was similar to that observed in previous studies. ICFEI presented characteristics similar to ICFEP in this study. Our data show that ICFEi had a better prognosis compared to the other two phenotypes.
FUNDAMENTO: A classificação da insuficiência cardíaca (IC) por fenótipos possui grande relevância na prática clínica. OBJETIVO: O estudo visou analisar a prevalência, as características clínicas e os desfechos entre os fenótipos de IC no contexto da atenção primária. MÉTODOS: Trata-se de uma análise de um estudo de coorte que incluiu 560 indivíduos, com idade ≥ 45 anos, que foram selecionados aleatoriamente em um programa de atenção primária. Todos os participantes foram submetidos a avaliações clínicas, dosagem do peptídeo natriurético tipo B (BNP), eletrocardiograma e ecocardiografia em um único dia. A IC com fração de ejeção do ventrículo esquerdo (FEVE) < 40% foi classificado como IC com fração de ejeção reduzida (ICFEr), FEVE de 40% a 49% como IC com fração de ejeção intermediária (ICFEi) e FEVE ≥ 50% como IC com fração de ejeção preservada (ICFEp). Após 5 anos, os pacientes foram reavaliados quanto à ocorrência do desfecho composto de óbito por qualquer causa ou internação por doença cardiovascular. RESULTADOS: Dos 560 pacientes incluídos, 51 pacientes tinham IC (9,1%), 11 dos quais tinham ICFEr (21,6%), 10 tinham ICFEi (19,6%) e 30 tinham ICFEp (58,8%). A ICFEi foi semelhante à ICFEp nos níveis de BNP (p < 0,001), índice de massa do ventrículo esquerdo (p = 0,037) e índice de volume do átrio esquerdo (p < 0,001). O fenótipo de ICFEi foi semelhante ao de ICFEr em relação à doença arterial coronariana (p = 0,009). Após 5 anos, os pacientes com ICFEi apresentaram melhor prognóstico quando comparados aos pacientes com ICFEp e ICFEr (p < 0,001). CONCLUSÃO: A prevalência de ICFEI foi semelhante ao observado em estudos anteriores. A ICFEI apresentou características semelhantes a ICFEP neste estudo. Nossos dados mostram que a ICFEi teve melhor prognóstico em comparação com os outros dois fenótipos.

Thyroid nodules (TN) are common in the general population, and the clinical importance of diagnosing thyroid nodules is based on excluding the possibility of thyroid cancer, which occurs in 7-15% of cases. The thyroid gland, owing to its superficial location, is easily accessible via thermography, a noninvasive method of recording body temperature that measures infrared radiation emitted by the body surface. Therefore, this study aimed to evaluate the temperature differences between benign and malignant TN by using thermography. We conducted a cross-sectional study where 147 TN were divided into two groups: the first group included 120 benign nodules and the other included 27 malignant nodules. All the nodules were subjected to ultrasound, fine needle aspiration biopsy, and thermography. On analyzing the thermography results, the benign nodules had a higher temperature at the beginning of the thermography evaluation, and the malignant nodules showed a higher temperature in the middle and at the end (Ft). Using the relationships, it was observed that the temperature delta (ΔT), ΔT nodule/ΔT healthy, ΔT nodule minus ΔT healthy, and nodule Ft minus Ft of the healthy region were higher in malignant nodules. The ROC curve analysis of ΔT demonstrated a cutoff point of 2.38°C, with a sensitivity of 0.963 and specificity of 0.992. Malignant nodules have higher temperatures than benign nodules on thermographic evaluation. This finding suggests that thermography can be a useful tool in the diagnosis of thyroid nodules.

Abstract: Introduction: The development of clinical reasoning to diagnose diseases and order ancillary tests, such as radiology imaging, is based on history-taking and physical examination skills, which are developed during the semiology course. Objective: We aimed to evaluate the results of the innovative integration of two courses in the medical curriculum at our institution: Medical Semiology and Clinical Radiology. Methods: The sample consisted of 184 fifth-semester medical students attending the two courses simultaneously. Extra-class semiology-radiology sessions based on theoretical and practical topics integrating radiological images and semiological signs were conducted, and the results were assessed by applying a semi-structured questionnaire to the participants, in which all 18 items were rated on a scale from 0 (worst) to 10 (best). The normality hypothesis in score distribution was verified by the Kolmogorov-Smirnov test and the Shapiro-Wilk test. The distribution of the 18 scores were summarized by descriptive statistics and compared by Friedman's test, with post-hoc test in pairwise comparisons adjusted by Bonferroni test. Correlations between the scores were determined by Spearman's Rank Correlation Coefficients. Results: The overall mean score for the semiology-radiology sessions was high (8.55). Students were satisfied with the selection of clinical cases (8.46) and found that the semiology-radiology sessions contributed to the development of their clinical reasoning (8.58). Conclusion: Medical schools are facing new challenges in medical education. The innovative concept of Radiology-Semiology integrated teaching modality affects the students' self-perception ability to interpret radiological images and might be an educational strategy trend.
Resumo: Introdução: O desenvolvimento do raciocínio clínico para diagnosticar doenças e solicitar exames complementares, como os radiológicos, baseia-se na história e no exame físico, desenvolvidos durante o curso de Semiologia. Objetivo: Nosso objetivo foi avaliar os resultados da integração inovadora de duas disciplinas no currículo médico em nossa instituição: Semiologia Médica e Radiologia Clínica. Métodos: A amostra foi composta por 184 estudantes de Medicina do quinto semestre que participaram das duas disciplinas simultaneamente. Realizaram-se sessões extraclasse de semiologia e radiologia, baseadas em tópicos teóricos e práticos, integrando imagens radiológicas com sinais semiológicos. Avaliaram-se os resultados por meio da aplicação de um questionário semiestruturado aos participantes, no qual todos os 18 itens foram classificados em uma escala de 0 (pior) a 10 (melhor). A hipótese de normalidade na distribuição dos escores foi verificada pelos testes de Kolmorov-Smirnov e Shapiro-Wilk. As 18 distribuições de pontuação foram resumidas por estatística descritiva e comparadas pelo teste de Friedman, com teste post hoc em comparações pareadas ajustadas por Bonferroni. As correlações entre as pontuações foram determinadas pelos coeficientes de correlação de classificação de Spearman. Resultados: O escore médio geral para as sessões de semiologia e radiologia foi alto (8,55). Os estudantes ficaram satisfeitos com a seleção de casos clínicos (8,46) e descobriram que as sessões de semiologia-radiologia contribuíram para o desenvolvimento de seu raciocínio clínico (8,58). Conclusão: As escolas médicas enfrentam novos desafios na educação médica. O conceito inovador da modalidade de ensino integrado de radiologia-semiologia afeta a capacidade de autopercepção dos alunos para interpretar imagens radiológicas e pode ser uma tendência de estratégia educacional.

Abstract Background: Primary care physicians have difficulty dealing with patients who have HF with preserved LVEF(HFpEF). The prognosis of HFpEF is poor, and difficult to predict on primary care. Objective: The aim of the study is to apply the H2FPEF score to primary care patients and verify its power to assess the risk of death or hospitalization due to cardiovascular disease. Methods: This longitudinal study included 402 individuals, with signs or symptoms of HF, aged≥45 years and, underwent an evaluation which included clinical examination, BNP and echocardiogram. The diagnosis of HFpEF was confirmed by the criteria of the European Society of Cardiology. After five years, the patients were reassessed as to the occurrence of the composite outcome, death from any cause or hospitalization for cardiovascular disease. H2FPEF used six variables: body mass index, medications for hypertension, age, pulmonary artery systolic pressure, atrial fibrillation and E/e' ratio ranged from 0 to 9 points. The level of statistical significance was p<0.05. Results: HFpEF was diagnosed in 58(14.4%). Among patients with H2FPEF≥4, 30% had HFpEF and in those with a score≤4, HFpEF was present in 12%. Patients with HFpEF and H2FPEF≥4 had 53% of outcomes, whereas patients with HFpEF and a score ≤4 had a 21% of outcomes. BNP values were higher in patients with HFpEF compared to those without HFpEF(p<0.0001). Conclusion: H2FPEF≥4 indicated a worse prognosis in patients with HFpEF assisted in primary care. H2FPEF may be a simple and useful tool for risk stratification in patients with HFpEF at the primary care.

BACKGROUND: Longevity, combined with a higher prevalence of obesity, particularly visceral obesity, has been associated with an increased risk of cardiovascular diseases. Insulin resistance (IR) is an important link between visceral obesity and cardiovascular diseases. An important association has been found between sagittal abdominal diameter, visceral obesity and IR. The objective of this study is to evaluate sagittal abdominal diameter as a marker of visceral obesity and correlate it with IR in older primary health care patients. METHODS: A cross-sectional study was performed with 389 patients over 60 years of age (70.6 ± 6.9), of whom 74% were female. Their clinical, anthropometric and metabolic profiles were assessed and their fasting serum insulin level was used to calculate the homeostasis model assessment insulin resistance (HOMA-IR). Sagittal abdominal diameter was measured in the supine position at the midpoint between the iliac crest and the last rib with abdominal calipers. RESULTS: Sagittal abdominal diameter was significantly correlated with anthropometric measures of general and visceral obesity and with HOMA-IR in both genders. There was no change in the association between sagittal abdominal diameter and HOMA-IR after adjusting for age, sex, diabetes and hypertension. CONCLUSION: It is feasible to use sagittal abdominal diameter in older primary care patients as a tool to evaluate visceral obesity, which is an indicator of cardiovascular risk.
RESUMEN
This study focused on the correlation between neck circumference and other anthropometric measurements and cardiovascular risk factors and insulin resistance in the elderly in Niterói, Rio de Janeiro State, Brazil. This was a cross-sectional study in 411 patients seen in primary care. Anthropometric measurements including neck circumference, body mass index (BMI), waist circumference (WC), and waist-hip ratio (WHR) were recorded. Bioelectrical impedance analysis (BIA) estimated the percentage of total body fat (%TBF). Insulin resistance was estimated by HOMA-IR (homeostasis model assessment IR index). The data were analyzed by the Mann-Whitney test and the correlation between numerical variables by Spearman's test. Receiver operating characteristic (ROC) was used to assess the anthropometric measurements' predictive capacity to diagnosis insulin resistance. Neck circumference was positively correlated with WC, BMI, WHR, %TBF, and HOMA-IR in both sexes. In women, neck circumference showed higher AUC (area under the curve) for insulin resistance. In men, WC showed higher AUC, followed by BMI and neck circumference. The current study in Southeast Brazil suggests that neck circumference can predict insulin resistance, an important marker of cardiovascular risk in the elderly population treated in primary care.

Resumo: O presente estudo investigou a correlação da circunferência do pescoço (CP) e outras medidas antropométricas com os fatores de risco cardiovasculares e resistência insulínica (RI) em idosos de Niterói, Rio de Janeiro, Brasil. Foi realizado estudo transversal com 411 pacientes na atenção primária de saúde. Medidas antropométricas como CP, índice de massa corporal (IMC), circunferência da cintura (CC) e razão cintura-quadril (RCQ) foram aferidas. A bioimpedância elétrica (BIA) estimou o percentual da gordura corporal total (%GC). A resistência à insulina foi estimada pelo HOMA-IR (homeostasis model assessment IR index). Os dados foram analisados utilizando o teste de Mann-Whitney e a correlação entre as variáveis numéricas pelo teste de Spearman. A curva ROC (receiver operating characteristic) foi utilizada para avaliar a capacidade preditiva das medidas antropométricas no diagnóstico de RI. A CP foi positivamente correlacionada com a CC, o IMC, RCQ, %TBF e com o HOMA-IR em ambos os sexos. Nas mulheres, a CP apresentou a maior AUC (área sob a curva) para RI. Nos homens, a CC apresentou a maior AUC, seguido pelo IMC e CP. O presente estudo realizado no Sudeste do Brasil sugere que a CP pode predizer a RI, importante marcador de risco cardiovascular, na população idosa atendida na atenção primária de saúde.
Resumen: El presente estudio investigó la correlación de la circunferencia del cuello (CP) y otras medidas antropométricas con los factores de riesgo cardiovasculares y resistencia a la insulina (RI) en ancianos de Niterói, Río de Janeiro, Brasil. Fue realizado estudio transversal con 411 pacientes en la atención primaria de salud. Medidas antropométricas como CP, índice de masa corporal (IMC), circunferencia de la cintura (CC) y razón cintura-cadera (RCC) fueron tomadas con precisión. La bioimpedancia eléctrica (BIA) estimó el porcentaje de la grasa corporal total (%GC). La resistencia a la insulina se estimó por el HOMA-IR (homeostasis model assessment IR index). Los datos se analizaron utilizando el test de Mann-Whitney y la correlación entre las variables numéricas por el test de Spearman. La curva ROC (receiver operating characteristic) fue utilizada para evaluar la capacidad predictiva de las medidas antropométricas en el diagnóstico de RI. La CP fue positivamente correlacionada con la CC, el IMC, RCC, %TBF y con el HOMA-IR en ambos sexos. En las mujeres, la CP presentó la mayor AUC (área bajo la curva) para RI. En los hombres, la CC presentó la mayor AUC, seguido por el IMC y CP. El presente estudio realizado en el sudeste de Brasil sugiere que la CP puede predecir la RI, importante marcador de riesgo cardiovascular, en la población anciana atendida en la atención primaria de salud.

BACKGROUND: Metabolic syndrome (MS) is an aggregation of risk factors that increase the incidence of cardiovascular events and diabetes mellitus (DM). Population aging is accompanied by higher prevalence of MS, which varies depending on the population studied and the diagnostic criteria used. OBJECTIVE: To determine prevalence of MS in the elderly using four diagnostic criteria and agreement between them. METHODS: Cross-sectional study on 243 patients older than 60 years (180 women) in Niterói, RJ. They were evaluated by clinical examination, fasting glucose, fasting insulin, lipid profile and anthropometric measurements - weight, height, waist circumference and waist/hip ratio. Prevalence of MS was estimated by World Health Organization (WHO) modified, National Cholesterol Education Program - Adult Treatment Panel III (NCEP-ATP III), International Diabetes Federation (IDF) and Joint Interim Statement (JIS) criteria. RESULTS: Prevalence was high with the four criteria WHO (51.9%), NCEP-ATPIII (45.2%), IDF (64.1%) and JIS (69.1%), and agreement between criteria by kappa was moderate in almost all comparisons WHO vs. IDF (k = 0.47;95% confidence interval (CI), 0.35 to 0.58); WHO vs. NCEP-ATPIII (k = 0.51; 95% CI, 0.40 to 0.61); WHO vs. JIS (k = 0.45; 95% CI, 0.33 to 0.56); IDF vs. NCEP-ATPIII (k = 0.55; 95% CI, 0.45 to 0.65) and NCEP-ATPIII vs. JIS (k = 0.53; 95% CI, 0.43-0.64), except between IDF vs. JIS (K = 0.89;95% CI, 0.83 to 0.95), which was considered good. CONCLUSION: Prevalence of MS was high with the four diagnostic criteria, mainly by JIS. There was good agreement between JIS and IDF criteria and moderate among the others.

Fundamento: A Síndrome Metabólica (SM) é uma agregação de fatores de risco que aumenta a incidência de eventos cardiovasculares e Diabete Melito (DM). O envelhecimento da população vem acompanhado de maior prevalência de SM, que varia dependendo da população estudada e do critério diagnóstico utilizado. Objetivo: Determinar a prevalência de SM em idosos por quatro critérios diagnósticos e a concordância entre esses. Métodos: Estudo transversal realizado em 243 indivíduos acima de 60 anos (180 mulheres) em Niterói (RJ). Foram avaliados através de exame clínico glicemia jejum, insulinemia jejum, perfil lipídico e medidas antropométricas - peso, estatura, circunferência abdominal e relação cintura/quadril. A prevalência de SM foi estimada utilizando critérios diagnósticos da Organização Mundial da Saúde (OMS) modificado, National Cholesterol Education Program - Adult Treatment Panel III (NCEP-ATPIII), International Diabetes Federation (IDF) e Joint Interim Statement (JIS). Resultados: A prevalência foi elevada pelos quatro critérios, OMS (51,9%), NCEP-ATPIII (45,2%), IDF (64,1%) e JIS (69,1%), e a concordância entre os critérios diagnósticos pelo índice kappa foi moderada em quase todas as comparações OMS vs. IDF (k = 0,47; intervalo de confiança (IC) 95%, 0,35 - 0,58); OMS vs. NCEP-ATPIII (k = 0,51; IC 95%, 0,40 - 0,61); OMS vs. JIS (k = 0,45; IC 95%, 0,33 - 0,56); IDF vs. NCEP-ATPIII (k = 0,55, IC 95%, 0,45 - 0,65) e NCEP-ATPIII vs. JIS (k = 0,53; IC 95%, 0,43 - 0,64), exceto entre IDF vs. JIS (K= 0,89; IC 95%, 0,83 - 0,95), considerada boa.
