SUMMARY OBJECTIVE: The aim of this study was to assess the performance of the CALL Score tool in predicting the death outcome in COVID-19 patients. METHODS: A total of 897 patients were analyzed. Univariate and multivariate logistic regression analyses were conducted to determine the association between characteristics of the CALL Score and the occurrence of death. The relationship between CALL Score risk classification and the occurrence of death was also examined. Receiver operating characteristic curve analysis was performed to identify optimal cutoff points for the CALL Score and the outcome. RESULTS: The study revealed that age>60 years, DHL>500, and lymphocyte count ≤1000 emerged as independent predictors of death. Higher risk classifications of the CALL Score were associated with an increased likelihood of death. The optimal CALL Score cutoff point for predicting the death outcome was 9.5 (≥9.5), with a sensitivity of 70.4%, specificity of 80.3%, and accuracy of 80%. CONCLUSION: The CALL Score showed promising discriminatory ability for death outcomes in COVID-19 patients. Age, DHL level, and lymphocyte count were identified as independent predictors. Further validation and external evaluation are necessary to establish the robustness and generalizability of the CALL Score in diverse clinical settings.

Abstract Background Heart failure (HF) is worldwide known as a public health issue with high morbimortality. One of the issues related to the evolution of HF is the high rate of hospital readmission caused by decompensation of the clinical condition, with high costs and worsening of ventricular function. Objective To quantify the readmission rate and identify the predictors of rehospitalization in patients with acute decompensated heart failure. Methods Hospital-based historic cohort of patients admitted with acute decompensated HF in a private hospital from Recife/PE, from January 2008 to February 2016, followed-up for at least 30 days after discharge. Demographic and clinical data of admission, hospitalization, and clinical and late outcomes were analyzed. Logistic regression was used as a strategy to identify the predictors of independent risks. Results 312 followed-up patients, average age 73 (± 14), 61% males, 51% NYHA Class III, and 58% ischemic etiology. Thirty-day readmission rate was 23%. Multivariate analysis identified the independent predictors ejection fraction < 40% (OR = 2.1; p = 0.009), hyponatremia (OR = 2.9; p = 0.022) and acute coronary syndrome (ACS) as the cause of decompensation (OR = 1.1; p = 0,026). The final model using those three variables presented reasonable discriminatory power (C-Statistics = 0.655 – HF 95%: 0.582 – 0.728) and good calibration (Hosmer-Lemeshow p = 0.925). Conclusions Among hospitalized patients with acute decompensated heart failure, the rate of readmission was high. Hyponatremia, reduced ejection fraction and ACS as causes of decompensation were robust markers for the prediction of hospital readmission within 30 days of discharge.

Abstract Background: Recently, a new HF entity, with LVEF between 40-49%, was presented to comprehend and seek better therapy for HF with preserved LVEF (HFpEF) and borderline, in the means that HF with reduced LVEF (HFrEF) already has well-defined therapy in the literature. Objective: To compare the clinical-therapeutic profile of patients with HF with mid-range LVEF (HFmrEF) with HFpEF and HFrEF and to verify predictors of hospital mortality. Method: Historical cohort of patients admitted with decompensated HF at a supplementary hospital in Recife/PE between April/2007 - August/2017, stratified by LVEF (< 40%/40 - 49/≥ 50%), based on the guideline of the European Society of Cardiology (ESC) 2016. The groups were compared and Logistic Regression was used to identify predictors of independent risk for in-hospital death. Results: A sample of 493 patients, most with HFrEF (43%), HFpEF (30%) and HFmrEF (26%). Average age of 73 (± 14) years, 59% men. Hospital mortality 14%, readmission within 30 days 19%. In therapeutics, it presented statistical significance among the 3 groups, spironolactone, in HFrEF patients. Hospital death and readmission within 30 days did not make difference. In the HFmrEF group, factors independently associated with death were: valve disease (OR: 4.17, CI: 1.01-9.13), altered urea at admission (OR: 6.18, CI: 1.78-11.45) and beta-blocker hospitalization (OR: 0.29, CI: 0.08-0.97). In HFrEF, predictors were: prior renal disease (OR: 2.84, CI: 1.19-6.79), beta-blocker at admission (OR: 0.29, CI: 0.12-0.72) and ACEI/ ARB (OR: 0.21, CI: 0.09-0.49). In HFpEF, only valve disease (OR: 4.61, CI: 1.33-15.96) and kidney disease (OR: 5.18, CI: 1.68-11.98) were relevant. Conclusion: In general, HFmrEF presented intermediate characteristics between HFrEF and HFpEF. Independent predictors of mortality may support risk stratification and management of this group.

Abstract INTRODUCTION: Chagas disease (CD) is a neglected disease caused by the parasite Trypanosoma cruzi. One-third of infected patients will develop the cardiac form, which may progress to heart failure (HF). However, the factors that determine disease progression remain unclear. Increased angiotensin II activity is a key player in the pathophysiology of HF. A functional polymorphism of the angiotensin-converting enzyme (ACE) gene is associated with plasma enzyme activity. In CD, ACE inhibitors have beneficial effects supporting the use of this treatment in chagasic cardiomyopathy. METHODS: We evaluated the association of ACE I/D polymorphism with HF, performing a case-control study encompassing 343 patients with positive serology for CD staged as non-cardiomyopathy (stage A; 100), mild (stage B1; 144), and severe (stage C; 99) forms of Chagas heart disease. For ACE I/D genotyping by PCR, groups were compared using unconditional logistic regression analysis and adjusted for nongenetic covariates: age, sex, and trypanocidal treatment. RESULTS: A marginal, but not significant (p=0.06) higher prevalence of ACE I/D polymorphism was observed in patients in stage C compared with patients in stage A. Patients in stage C (CD with HF), were compared with patients in stages A and B1 combined into one group (CD without HF); DD genotype/D carriers were prevalent in the HF patients (OR = 2; CI = 1.013.96; p = 0.04). CONCLUSIONS: Our results of this cohort study, comprising a population from the Northeast region of Brazil, suggest that ACE I/D polymorphism is more prevalent in the cardiac form of Chagas disease with HF.

OBJETIVO: Avaliar o impacto das doenças oculares sobre a qualidade de vida de uma população idosa do sertão de Pernambuco, localizado na região nordeste do Brasil. MÉTODOS: Foram entrevistados 580 indivíduos acima de 59 anos, por meio do questionário de avaliação de qualidade de vida "Visual Functioning Questionnaire" (VFQ). Todos os indivíduos foram submetidos a exame oftalmológico completo. Os resultados das variáveis quantitativas foram expressos por suas médias e desvios- padrão. Os resultados das variáveis qualitativas foram expressos por suas frequências absolutas e relativas. RESULTADOS: A média de idade foi de 70 ± 8,1 anos. Cerca de 86,0% dos entrevistados declararam ser analfabetos ou ter o ensino fundamental incompleto. As principais queixas foram: baixa visual (71,1%) e ardor/prurido (69,0%). A acuidade visual não era normal em 37,4% dos idosos. Por volta de 75,0% dos entrevistados relataram ter saúde regular ou ruim, e 77,0% diziam ter uma visão regular ou ruim. A qualidade de vida foi considerada pior conforme a piora da condição visual do idoso. CONCLUSÃO: O déficit visual representou um impacto negativo sobre a qualidade de vida dos idosos do sertão Pernambucano.

PURPOSE: To evaluate the impact of visual impairment on the quality of life of the elderly population living in the western countryside of Pernambuco State, located in northeast of Brazil. METHODS: Five hundred and eighty subjects over 59 years of age were interviewed using the Visual Functioning Questionnaire (VFQ). All subjects underwent complete eye examination. The results of the quantitative parameters were expressed by mean ± SD. The results of categorical parameters were expressed by their frequencies. RESULTS: Mean age was of 70 ± 8.1 years. About 86% of the interviewed elderly were illiterate or had incomplete education. The mean complaints were low visual acuity (71.1%) and itching/burning (69.0%). The visual acuity was not normal in 37.4% of the elderly. About 75.0% of the subjects reported to have regular or bad health, and 77.0% reported to have regular or bad vision. The reported quality of life decreased according to the worsening of the visual acuity. CONCLUSION: Visual impairment had a negative impact on the quality of life of the elderly population from the western countryside of Pernambuco State.

OBJETIVOS: Identificar precocemente a prevalência de aterosclerose, por causa do espessamento do complexo médio-intimal das carótidas comuns e do índice tornozelo-braço. Essas medidas foram relacionadas com os fatores de risco clássicos de aterosclerose e os específicos dos infectados pelo HIV (tempo de doença, tempo de tratamento, tipo de tratamento, tipo de terapia antirretroviral utilizada, CD4 e carga viral). MÉTODOS: Setenta casos infectados com o HIV foram avaliados pela medida automática do complexo médio-intimal nas carótidas e do índice tornozelo-braço. Consideraram-se os fatores de risco clássicos de aterosclerose (idade, sexo, hipertensão arterial sistêmica, tabagismo, hipercolesterolemia, hipertrigliceridemia, obesidade e história familiar de evento cardiovascular), as medidas antropométricas e as variáveis relacionadas ao HIV. O nível de significância assumido foi de 5%. RESULTADOS: O tempo médio de diagnóstico do HIV foi de 104,9 meses e de tratamento foi de 97,9 meses. Quanto ao tipo de tratamento, 47 (67,1%) fizeram uso de inibidor de protease por mais de seis meses e 36 (51,4%) estão em uso atualmente. O índice tornozelo-braço estava aumentado em um único paciente (0,7%) e não se evidenciou espessamento do complexo médio-intimal em nenhum indivíduo. Não existiu associação significante da medida do complexo médio-intimal da carótida comum direita com nenhuma das variáveis analisadas. CONCLUSÕES: Indivíduos jovens, sob o uso de terapia antirretroviral por cinco anos ou mais, não apresentaram espessamento do complexo médio-intimal ou aumento do índice tornozelo-braço. Não houve diferença do espessamento do complexo médio-intimal associada ao tipo de esquema antirretroviral utilizado ou nível de carga viral.

OBJECTIVES: To precociously identify the prevalence of atherosclerosis caused by thickening of the intima-media complex of the common carotid arteries and of the ankle brachial index. These measurements were associated with the classical risk factors of atherosclerosis and the specific factors of those infected by HIV (duration of disease, length of treatment, kind of treatment, kind of antiretroviral therapy used, CD4 and viral load). METHODS: Seventy cases infected by HIV were assessed by automatic measurement of the intima-media complex in the carotids and of the ankle brachial index. The classical risk factors of atherosclerosis (age, gender, systemic arterial hypertension, smoking, hypercholesterolemia, hypertriglyceridemia, obesity, and family history of cardiovascular events), anthropometric measurements and the variables related to HIV were taken into consideration. The adopted level of significance was 5%. RESULTS: The mean time of HIV diagnosis was 104.9 months, mean duration of treatment was 97.9 months. As regard to the type of treatment, 47 (67.1%) used protease inhibitor for more than six months and 36 (51.4%) are using it recently. The ankle brachial index was increased in one patient (0.7%), and the intima-media complex was not thickened in any individual. There was no significant association of the measurement of the intima-media complex of the right common carotid with any of the variables analyzed. CONCLUSIONS: Young individuals under the use of antiretroviral therapy for five years or more did not show increase in thickness of the intima-media complex or increase in the ankle brachial index, and there was no difference in the intima-media complex thickness associated with the therapeutical scheme of antiretroviral used or the viral load level.

CONTEXTO: Tem sido descrita correlação entre os níveis séricos de globulinas e o grau de fibrose hepática nas hepatites crônicas, mas não se encontram relatos na esquistossomose mansônica. OBJETIVO: Avaliar os níveis séricos de globulinas e de IgG, e a intensidade da fibrose periportal mensurada pela ultrassonografia em pacientes com esquistossomose mansônica. MÉTODOS: Entre novembro de 2006 e fevereiro de 2007, foram estudados 41 pacientes que preencheram ficha clínica e realizaram dosagens de IgG por imunoturbidimetria e de globulinas indiretamente pelo método do biureto. A ultrassonografia foi realizada por um único pesquisador, seguindo os protocolos do Cairo e de Niamey. RESULTADOS: A média de idade foi 41 anos, sendo 25 pacientes (61%) do sexo feminino. Dez dos 41 pacientes (24%) apresentaram elevação dos níveis séricos de globulinas e 21 (51%) dos de IgG. Conforme a classificação do Cairo, 21 pacientes apresentaram grau I de fibrose, 18 grau II e 2 grau III, e pela classificação de Niamey 8 apresentavam padrão C, 20 D e 13 E. Aqueles com graus II ou III de fibrose tiveram maiores níveis de IgG do que os de grau I (P = 0,047), assim como aqueles que apresentaram padrões D e E em relação ao C (P = 0,011). Não houve associação entre os níveis de globulinas e o grau ou padrão de fibrose. CONCLUSÃO: Em pacientes com esquistossomose mansônica, observou-se elevação dos níveis séricos de IgG de acordo com a progressão do grau e do padrão de fibrose periportal, mas o mesmo não se observou com os níveis de globulinas.

BACKGROUND: A correlation between the levels of serum globulins and the hepatic fibrosis degree in chronic hepatitis was described, but reports in schistosomiasis mansoni have not been found. OBJECTIVE: To evaluate the serum globulins and IgG levels, and periportal fibrosis intensity measured by ultrasound in patients with schistosomiasis mansoni. METHODS: Between November, 2006 and February 2007, 41 patients which were eligible, filled them a questionnaire and had their levels of serum IgG measured by immunoturbidimetry and globulins indirectly measured by the Biuret method. The ultrasound was carried out by a single researcher, according to the Cairo and Niamey protocols. RESULTS: The average age was 41 years old and 25 female patients (61%). Ten patients (24%) from 41 showed serum globulins levels raised and 21 (51%) presented elevated IgG levels. According to the Cairo classification, 21 patients showed grade I of fibrosis, 18 grade II and 2 grade III; and by the Niamey classification 8 showed standard C, 20 D, and 13 E. Those with grade II or III of fibrosis had higher IgG levels than the ones with grade I (P = 0,047), as well as those who showed standards D and E as compared to C (P = 0,011). There was no association between the globulins levels and the intensity of fibrosis. CONCLUSION: In patients with schistosomiasis mansoni, an increase of the IgG serum levels was observed according to the progression from periportal fibrosis intensity, but the same was not founded with globulins levels.

OBJETIVO: Investigar se a hiper-homocisteinemia é fator de risco independente para doença aterosclerótica coronariana em idosos. MÉTODOS: Estudo caso-controle com 172 idosos, 88 pertencentes ao grupo controle e 84 ao grupo caso, que apresentavam cineangiocoronariografia solicitada por indicações clínicas. Angiografia coronariana quantitativa foi realizada em 91% dos pacientes. Homocisteinemia foi avaliada sob forma contínua e categorizada, por análise univariada e multivariada. RESULTADOS: Quando analisada sob forma contínua, verificou-se que, na análise univariada, os idosos do grupo caso apresentaram média de níveis de homocisteinemia significativamente mais elevada que a dos idosos do grupo controle (14,33±4,59 µmol/l versus 11,99± 4,59 µmol/l , p=0,015). Na análise multivariada, a homocisteinemia sob forma contínua associou-se a razão de risco para doença arterial coronariana de 1,07 a cada aumento de 1 µmol/l de nível de homocisteína. Aumento de 5 µmol/l correspondeu a razão de risco de 1,40. Quando analisada sob forma categorizada, definiu-se como hiper-homocisteinemia os valores encontrados acima do percentil 75 do grupo controle (14 µmol/l ). Hiper-homocisteinemia foi encontrada em 34% dos idosos, sendo 37,3% no grupo controle e 62,7% no grupo caso (p=0,009). Na análise multivariada, a hiperhomocisteinemia constituiu fator de risco independente para doença aterosclerótica coronariana em idosos, com razão de risco para doença arterial coronariana de 2,03, intervalo de confiança 95%, 1,02-4,03. CONCLUSÃO: Hiper-homocisteinemia foi fator de risco independente para doença arterial coronariana em idosos.

OBJECTIVE: To investigate whether hyperhomocysteinemia is an independent risk factor for atherosclerotic disease in elderly individuals METHODS: A case-control study with 172 elderly individuals, 88 belonging to control group and 84 to case group, who showed coronary angiography requested for clinical indications. Quantitative coronary angiography was performed in 91% of the patients. Homocysteinemia was assessed in a continuous and categorized way, through univariate and multivariate analysis. RESULTS: When analyzed continuously, in univariate analysis, it was verified that case group elderly individuals showed an average homocysteinemia levels significantly higher than the control group individuals' (14.33±4.59 µmol/l against 11.99±4.59 µmol/l, p=0.015). In multivariate analysis, continuous homocysteinemia was associated to the risk rate for coronary artery disease of 1.07 for each 1 µmol/l increase of homocysteine level. Na increase of 5 µmol/l corresponded to the risk rate of 1.40. When analyzed in categorized way, the values found over percentile 75 of control group (14 µmol/l) were defined as hyperhomocysteinemia. Hyperhomocysteinemia was found in 34% of elderly individuals, being 37.3% in control group and 62.7% in case group (p= 0.009). In multivariate analysis, hyperhomocysteinemia constituted an independent risk factor for coronary atherosclerotic disease for elderly individuals, with a risk rate for coronary artery disease of 2.03, confidence interval 95%, 1.02-4.03. CONCLUSION: Hyperhomocysteinemia was an independent risk factor for coronary artery disease in elderly individuals.

OBJETIVO: Verificar o efeito prognóstico das alterações de quatro marcadores de lesão miocárdica (CKMB atividade/massa e troponinas T e I) pós- stent em relação à ocorrência de morte, infarto e novos procedimentos de revascularização em um ano e determinar a incidência e as variáveis preditoras de suas elevações. MÉTODOS: Em 199 pacientes tratados por stents em artérias naturais foram mensurados os quatro marcadores em três períodos: pré-procedimento, 6-8h e 14-18h pós-stent. Curvas de sobrevivência e a regressão logística de Cox determinaram o impacto prognóstico das alterações na ocorrência de eventos cardíacos em um ano. RESULTADOS: A incidência das alterações dos 4 marcadores pós-stent é relativamente freqüente (6,1% a 32,8%), associa-se à maior complexidade das lesões tratadas (longas e angulações >45º) e ao desenvolvimento de intercorrências durante o procedimento (oclusão de ramos secundários, presença de angina e alterações eletrocardiográficas). A sobrevivência livre de infarto e nova revascularização foi significativamente menor somente nos pacientes com elevação da CKMB atividade pós-procedimento em comparação àqueles sem esta alteração (60% x 85,08%, p=0,025). Influenciaram a sobrevivência livre de eventos o diabetes mellitus (OR: 2,27, p=0,0256), pré-dilatação com balão (OR: 3,16, p=0,0082) e elevação da CKMB atividade pós-procedimento (OR: 3,64, p=0,0162). CONCLUSÃO: A recomendação da monitoração sistemática da CKMB atividade pós-stent coronário baseia-se na compreensão do seu comportamento clínico e laboratorial, nos resultados dos estudos que relacionam a elevação de seus níveis pós-procedimento à pior evolução tardia e ao baixo custo do exame.

OBJECTIVE: To assess the prognostic effect of the changes in the levels of 4 biochemical markers of myocardial damage (CK-MB activity/mass and troponins T and I) after stent implantation in regard to the occurrence of death, infarction, and new myocardial revascularization procedures in a one-year period. The study also aimed at determining the incidence of their elevations and the existence of predictive variables. METHODS: Those 4 markers were measured in 199 patients treated with stent implantation in native arteries in the following 3 periods: before the procedure, 6-8 hours after the procedure, and 14-18 hours after the procedure. Survival curves and Cox logistic regression were used to determine the prognostic impact of the changes on the occurrence of cardiac events in one year. RESULTS: Changes in the levels of the 4 markers after stent implantation are relatively frequent (6.1% to 32.8%), are associated with the degree of complexity of the lesions treated (long lesions and angulations > 45º) and with the development of problems during the procedure (occlusion of the secondary branches, presence of angina, and electrocardiographic changes). The infarction-free survival rate and the need for a new revascularization were significantly lower only in the patients with an elevation in the CK-MB activity after the procedure as compared with those in patients without that alteration (60% x 85.08%; P=0.025). The following variables influenced the event-free survival rate: diabetes mellitus (OR: 2.27; P=0.0256), balloon predilation (OR: 3.16; P=0.0082), and an elevation in the CK-MB activity after the procedure (OR: 3.64; P=0.0162). CONCLUSION: Systematic monitoring of CK-MB activity after coronary stenting is justified due to its clinical and laboratory behavior reported in studies relating its elevation after the procedure to a worse late outcome, and due to its low cost.
