ABSTRACT

ABSTRACT Objective: To assess caregivers' perception about the changes in the daily habits of children and adolescents with type 1 diabetes during the COVID-19 pandemic. Subjects and methods: Primary caregivers of youth aged ≤18 with or without type 1 diabetes were selected for the diabetes and the control groups. Caregivers estimated the youth's time (hours) of physical activity and screen time before and during the pandemic, and rated the quality of eating habits and medication adherence from 0 to 10. The primary outcome was the change in physical activity time, screen time, and eating habits scores during isolation. Between-group analyses and within-group comparisons were conducted. A post hoc analysis was performed using logistic regression to correct for confounding factors. Results: In total, 764 participants were included (381 diabetes group vs. 383 control group). Before the pandemic, the diabetes group presented a reduced median of physical activity (P < 0.001) and screen time (P < 0.001). During the pandemic, the difference between both groups remained similar (P = 0.58). Scores of quality of eating habits were similar in both groups before the pandemic [8.0 (7.0-9.0) vs. 8.0 (7.0-9.0), P = 0.31] but decreased during the pandemic [7.0 (5.1-8.1) vs. 8.0 (6.0-9.0), P < 0.001]. The diabetes group had a significantly worse change in eating habits scores (P < 0.01). Conclusion: During the pandemic, eating habits were significantly worse in youth with diabetes than in those without diabetes.

ABSTRACT

Fundamento: A cirurgia de revascularização miocárdica (CRM) e a intervenção coronária percutânea (ICP) são estratégias amplamente utilizadas no manejo da doença arterial coronariana (DAC) estável. Objetivo: Avaliar o prognóstico de pacientes com DAC estável inicialmente tratada com terapia médica (TM), em comparação com os pacientes submetidos a procedimentos de revascularização. Métodos: Estudo prospectivo de coorte com 560 pacientes ambulatoriais de um hospital terciário com seguimento médio de 5 anos. Os pacientes foram classificados nos grupos TM (n = 288), ICP (n = 159) e CRM (n = 113) de acordo com sua estratégia inicial de tratamento. Os desfechos primários foram mortalidade global e eventos combinados de morte, síndrome coronária aguda e AVC. Resultados: Durante o seguimento, as taxas de mortalidade foram de 11,1% em TM, 11,9% em ICP e 15,9% em pacientes submetidos à CRM, sem diferença estatística (Hazard Ratio [HR] para ICP, 1,05; Intervalo de Confiança de 95% [IC95%], 0,59 a 1,84; e HR para CRM, 1,20; IC95%, 0,68 a 2,15). Os desfechos combinados ocorreram com maior frequência entre os pacientes inicialmente submetidos à ICP em relação à TM (HR 1,50, IC 95% 1,05 a 2,14) e não diferiram entre TM e CRM (HR 1,24, IC95% 0,84 a 1,83). Entre os pacientes com diabetes (n = 198), a ICP foi a única estratégia terapêutica preditiva de desfechos combinados (HR 2,14; IC 95%: 1,25 a 3,63). Conclusão: Neste estudo observacional de doença arterial coronariana estável, não houve diferença na mortalidade global entre as estratégias iniciais de terapia médico ou de cirurgia de revascularização. Os pacientes inicialmente tratados com ICP tiveram maior chance de desenvolver eventos cardiovasculares maiores combinados


Background: Coronary artery bypass grafting surgery (CABG) and percutaneous coronary intervention (PCI) are widely-used strategies in the management of stable coronary artery disease (CAD). Objective: To evaluate the prognosis of patients with stable CAD initially treated by medical therapy (MT), compared to the patients who were submitted to revascularization procedures. Methods: We conducted a prospective cohort study of 560 patients from an outpatient clinic in a tertiary hospital, with a mean follow-up of 5 years. Patients were classified into MT (n = 288), PCI (n = 159) and CABG (n=113) groups according to their initial treatment strategy. Primary endpoints were overall mortality and combined events of death, acute coronary syndrome, and stroke. Results: During follow-up, death rates were 11.1% in MT, 11.9% in PCI and 15.9% in CABG patients, with no statistical difference (hazard ratio [HR] for PCI, 1.05; 95% confidence interval [95%CI], 0.59 to 1.84; and HR for CABG, 1.20; 95% CI: 0.68 to 2.15). Combined outcomes occurred more often among patients initially submitted to PCI compared to MT (HR 1.50, 95% CI 1.05 to 2.14), and did not differ between MT and CABG patients (HR 1.24, 95% CI 0.84 to 1.83). Among patients with diabetes (n=198), PCI was the only therapeutic strategy predictive of combined outcomes (HR 2.14; 95% CI 1.25 to 3.63). Conclusion: In this observational study of stable coronary artery disease, there was no difference in overall mortality between initial medical therapy or revascularization surgery strategies. Patients initially treated with PCI had greater chance to develop combined major cardiovascular events

ABSTRACT

Fundamento: A equação de Friedewald (EF) é amplamente utilizada para estimar o LDL-c sem utilizar ultracentrifugação. Entretanto, a equação tem limitações em determinados cenários clínicos. Objetivo: O nosso objetivo era investigar a possível importância das diferenças entre a EF e a medição direta de LDL-c em pacientes com diabetes. Métodos: Realizamos um estudo transversal entre 466 pacientes com doença coronária estável. Colesterol total, triglicérides, HDL-c e LDL-c foram coletados, e a EF foi calculada. A acurácia foi calculada como percentagem de estimativas dentro de 30% (P30) do LDL medido. O viés foi calculado como a diferença média entre o LDL-c medido e o estimado. A concordância entre os métodos foi avaliada utilizando gráficos de Bland-Altman. Resultados: O viés foi de 3,7 (p=0,005) e 1,1 mg/dl (p=0,248), e a acurácia foi de 86% e 93% em pacientes diabéticos e não-diabéticos, respectivamente. Entre os pacientes com diabetes, o viés foi de 5 mg/dl (p=0,016) e 1,93 mg/dl (p=0,179), e a acurácia foi de 83% e 88% em indivíduos com hemoglobina A1c superior a 8 mg/dl versus abaixo do ponto de corte, respectivamente. O viés foi similar em pacientes sem diabetes comparados com pacientes com diabetes e HbA1C < 8 (1,1 e 1,93 mg/dl). Conclusão: A EF é imprecisa entre indivíduos gerais com diabetes. Porém, ao estratificar pacientes com diabetes em bom e mau controle da doença, o primeiro grupo se comporta como se não tivesse diabetes, com uma boa correlação entre o LDL-c calculado e o mensurado. É importante saber quando é razoável usar a EF, porque uma estimativa imprecisa dos níveis de LDL-c pode resultar no subtratamento da dislipidemia e predispor estes pacientes a eventos agudos


Background: Friedewald equation (FE) is widely used to estimate the LDL-c without the use of ultra-centrifugation. However, the equation has limitations in some clinical settings. Objective: Our goal was to investigate the potential importance of differences between FE and direct measurement of LDL-c in patients with diabetes. Methods: We conducted a cross-sectional study among 466 patients with stable coronary disease. Total cholesterol, triglycerides, HDL-c and LDL-c were collected, and FE was calculated. Accuracy was calculated as the percentage of estimates within 30% (P30) of measured LDL. Bias was calculated as the mean difference between measured and estimated LDL-c. Agreement between methods was evaluated using BlandAltman plots.Results: Bias was 3.7 (p=0.005) and 1.1 mg/dl (p=0.248), and accuracy was 86% and 93% in diabetic and non-diabetic patients, respectively. Among patients with diabetes, bias was 5 mg/dl (p=0.016) and 1.93 mg/dl (p=0.179), and accuracy was 83% and 88% in subjects with Hemoglobin A1C above 8 mg/dl versus below cutoff point, respectively. Bias was similar in patients without diabetes compared to patients with diabetes and HbA1C < 8 (1.1 and 1.93 mg/dl). Conclusion: FE is inaccurate among overall individuals with diabetes. However, when stratifying patients with diabetes into good and poor disease control, the first group behaves as if it does not have diabetes, with a good correlation between calculated and measured LDL-c.It is important to know when is it reasonable to use FE because an inaccurate estimation of LDL-c levels could result in undertreatment of dyslipidemia and predispose these patients to acute events

ABSTRACT

Linfoma não-Hodgkin sistêmico pode afetar o miocárdio, particularmente em pacientes imunocomprometidos. Quando presentes, sinais e sintomas são geralmente inespecíficos, tornando o diagnóstico de envolvimento cardíaco muito difícil antes da autópsia. Arritmias ventriculares também são pouco usuais nesse cenário. Descrevemos um caso de linfoma não-Hodgkin miocárdico secundário, que se apresentou com taquicardia ventricular monomórfica sustentada e espessamento do septo interventricular basal. Completa remissão das lesões miocárdicas foi observada após o término da quimioterapia de segunda linha, sem recorrências posteriores de arritmias em oito meses.


Systemic non-Hodgkin's lymphoma can affect the myocardium, particularly in immunocompromised patients. When present, symptoms and signs are usually nonspecific, making the diagnosis of cardiac involvement very difficult before an autopsy. Ventricular arrhythmias are also unusual in this setting. We describe a case of secondary myocardial non-Hodgkin's lymphoma presenting with sustained monomorphic ventricular tachycardia and thickening of the basal interventricular septum. Complete remission of myocardial lesions was observed after completion of second-line chemotherapy treatment, without further recurrences of arrhythmias in eight months.

ABSTRACT

A proteína ligadora de ácidos graxos (FABP) possui baixo peso molecular (15kDa) e localização citosólica, estando presente em grandes concentrações nas células miocárdicas. Em virtude dessa características, recentemente seu uso tem sido proposto para a detecção precoce do infarto agudo do miocárdio. Aumentos significativos em sua concentração plasmática podem ser observados dentro de três horas do início dos sintomas, com retorno aos valores normais em torno de 24 horas. Além disso, sua sensibilidade e especificidade têm-se mostrado bastante elevadas. Os autores realizam extensa revisão do tema, abordando os principais aspectos desse novo marcador.


The fatty acid-binding protein (FABP) is a low molecular weight cytosolic protein (15kDa), found in high concentrations in myocardial cells. Due to these characteristics, is has recently been proposed its use to detect acute myocardial infarction. Plasmatic concentration values of this protein signicantly increased can be observed within three hours of the beginning of the symptoms and the level returns to normal in about 24 hours. In addition, its sensivity and specificity as biochemical infarction marker are very high. The authors reviewed this theme emphasizing the main positive aspects of this marker.

ABSTRACT

A localizaçäo muscular dos cistos hidáticos é incomum (0,5 a 5,4 por cento) e geralmente secundária à doença hepática ou pulmonar. Reporta-se um caso de hidatidose intramuscular glútea, chamando-se a atençäo para essa localizaçäo atípica da doença, que deve ser considerada na prática cirúrgica. A inexistência de cistos concomitantes nas sedes mais comuns confere interesse ainda maior ao caso apresentado
