ABSTRACT Purpose Oropharyngeal dysphagia (OD) is one of the possible outcomes in patients hospitalized with COVID-19 and also in the population hospitalized for the treatment of cardiovascular disease. Thus, knowing the predictive risk factors for OD may help with referral and early intervention. This study aimed to verify the association of different factors with OD in hospitalized individuals with cardiovascular disease and COVID-19. Methods Cross-sectional clinical study approved by the Research Ethics Committee (4,521,771). Clinical evaluation of swallowing was carried out in 72 adult patients with cardiovascular disease and COVID-19 hospitalized from April to September 2020. Individuals under 18 years of age and without previous cardiovascular disease were excluded. The presence of general clinical and/or neurological complications, pronation, stay in the intensive care unit (ICU), orotracheal intubation (OTI), tracheostomy tube, oxygen support and age were considered as predictive risk factors for oropharyngeal dysphagia. Fisher's exact test, Mann Whitney test and logistic regression model were used for analysis. Results General clinical complications (p=0.001), pronation (p=0.003), ICU stay (p=0.043), in addition to the need for oxygen supplementation (p=0.023) and age (p= 0 .037) were statistically significant factors associated. The pronation (0.013) and age (0.038) were independently associated with dysphagia. OTI (p=0.208), tracheostomy (p=0.707) and the presence of previous cerebrovascular accidents (p=0.493) were not statistically significant. Conclusion In this study, age and prone position were factors independently associated with oropharyngeal dysphagia, complications such as the need for oxygen supplementation, in addition to the need for ICU admission, were also associated factors in the population.

ABSTRACT Inactivated COVID-19 vaccines data in immunocompromised individuals are scarce. This trial assessed the immunogenicity of two CoronaVac doses and additional BNT162b2 mRNA vaccine doses in immunocompromised (IC) and immunocompetent (H) individuals. Adults with solid organ transplant (SOT), hematopoietic stem cell transplant, cancer, inborn immunity errors or rheumatic diseases were included in the IC group. Immunocompetent adults were used as control group for comparison. Participants received two CoronaVac doses within a 28-day interval. IC received two additional BNT162b2 doses and H received a third BNT162b2 dose (booster). Blood samples were collected at baseline, 28 days after each dose, pre-booster and at the trial end. We used three serological tests to detect antibodies to SARS-CoV-2 nucleocapsid (N), trimeric spike (S), and receptor binding domain (RBD). Outcomes included seroconversion rates (SCR), geometric mean titers (GMT) and GMT ratio (GMTR). A total of 241 IC and 100 H adults participated in the study. After two CoronaVac doses, IC had lower SCR than H: anti-N, 33.3% vs 79%; anti-S, 33.8% vs 86%, and anti-RBD, 48.5% vs 85%, respectively. IC also showed lower GMT than H: anti-N, 2.3 vs 15.1; anti-S, 58.8 vs 213.2 BAU/mL; and anti-RBD, 22.4 vs 168.0 U/mL, respectively. After the 3rd and 4th BNT162b2 doses, IC had significant anti-S and anti-RBD seroconversion, but still lower than H after the 3rd dose. After boosting, GMT increased in IC, but remained lower than in the H group. CoronaVac two-dose schedule immunogenicity was lower in IC than in H.

Abstract Background Atrial fibrillation (AF) is classified according to the amplitude of fibrillatory waves (f) into fine waves (fAF) and coarse waves (cAF). Objectives To correlate the amplitude of f waves with clinical, laboratory, electrocardiographic, and echocardiographic variables that indicate a high risk of thromboembolism and to assess their impact on the success of electrical cardioversion (ECV). Methods Retrospective, observational study that included 57 patients with persistent non-valvular AF who underwent ECV. The maximum amplitude of f waves was measured in lead V1. cAF was defined when f ≥ 1.0mm and fAF when f < 1.0mm. The findings were correlated with the indicated variables. Values of p < 0.05 were considered statistically significant. Results cAF (n = 35) was associated with greater success in ECV (94.3% vs. 72.7%, p = 0.036) even after adjusting for variables such as age and BMI (p = 0.026, OR = 11.8). Patients with fAF (n = 22) required more shocks and more energy to revert to sinus rhythm (p = 0.019 and p = 0.027, respectively). There was no significant association between f-wave amplitude and clinical, echocardiographic, and laboratory parameters. Conclusions The amplitude of f wave was not associated with echocardiographic, clinical and laboratory parameters that indicate a high risk of thromboembolism. cAF was associated with a higher chance of success reverting to sinus rhythm employing ECV. A greater number of shocks and energy were required for reversion to sinus rhythm in patients with fAF. (AF (f (fAF cAF. .

RESUMO Contexto: O carcinoma hepatocelular (CHC) é o tumor maligno hepático mais comum, e a cirrose é o principal fator de risco para o seu desenvolvimento. Objetivo: Avaliar o papel da medição da rigidez hepática por elastografia transitória (ET) como fator de risco para ocorrência de CHC em uma coorte prospectiva de pacientes brasileiros com cirrose por vírus da hepatite C (VHC). Métodos: Um total de 99 pacientes com VHC e medida de rigidez hepática ≥12 kilopascals (kPa) foram incluídos consecutivamente, entre 2011 e 2016. As variáveis do baseline foram avaliadas e a ocorrência de CHC foi documentada. Os testes de Kaplan-Meier e log-rank, além das análises uni e multivariadas de Cox avaliaram a associação entre as variáveis e os resultados clínicos. Resultados: A média de idade foi de 57,8±10,6 anos. Vinte (20,2%) pacientes desenvolveram CHC, num período médio de seguimento de 3,3 anos. Na análise de regressão logística univariada, as variáveis associadas à ocorrência de CHC foram: contagem de plaquetas mais baixa (P=0,0446), valores séricos mais elevados de alfa-fetoproteína (P=0,0041) e de bilirrubina (P=0,0008), maior pontuação do escore MELD (P=0,0068) e valores mais altos de rigidez hepática por ET (P=0,0354). A medição da rigidez hepática por ET foi independentemente associada ao desenvolvimento de CHC, e o melhor valor de corte para maior risco de CHC foi >21,1kPa (HR: 5,548; IC95%: 1,244-24,766; P=0,025). Conclusão: Um alto valor de rigidez hepática está relacionado substancialmente a um risco aumentado de ocorrência de CHC em pacientes brasileiros com cirrose por HCV.

ABSTRACT Background: Evaluate the role of liver stiffness measurement (LSM) by transient elastography (TE) as a risk factor for hepatocellular carcinoma (HCC) occurrence in a prospective cohort of Brazilian hepatitis C virus (HCV) patients with cirrhosis. Methods: A cohort of 99 consecutive HCV patients was included between 2011 and 2016 with baseline LSM ≥12 kilopascals (kPa). Baseline variables were evaluated and HCC occurrence was documented. Kaplan-Meier methods with a log-rank test and the use of cox univariate and multivariate analysis assessed the association between variables and clinical results. Results: The mean age was 57.8±10.6 years. In a follow-up over a mean of 3.3 years, 20 (20.2%) patients developed HCC. In univariate logistic regression analysis, variables associated with HCC occurrence were: lower platelet count (P=0.0446), higher serum alpha-fetoprotein (P=0.0041) and bilirubin (P=0.0008) values, higher Model for End-Stage Liver Disease (MELD) score (P=0.0068) and higher LSM (P=0.0354). LSM evaluated by TE was independently associated with HCC development, and the best cut-off value for higher HCC risk was >21.1 kPa (HR: 5.548; 95%CI: 1.244-24.766; P=0.025). Conclusion: A high value of liver stiffness relates substantially to an increased risk for HCC occurrence in Brazilian patients with cirrhosis due to HCV.

Resumo Fundamento O diagnóstico de síndrome coronária aguda (SCA) e a estratificação de risco contemporâneos são fundamentais para o manejo apropriado e redução da mortalidade e eventos isquêmicos recorrentes, tanto na fase aguda quanto após hospitalização. A Definição Universal de Infarto do Miocárdio recomenda a detecção de curva de troponina acima do limite superior do percentil 99. Objetivos Avaliar a ocorrência de óbito e infarto agudo do miocárdio (IAM) na fase precoce em pacientes sem elevação de troponina (<0,034 ng/mL), pacientes com mínima elevação [acima do percentil 99 (>0,034 ng/mL e <0,12 ng/mL)], e pacientes com maiores elevações [acima do ponto de corte para IAM pelo kit utilizado (≥0,12 ng/mL)]; e avaliar o impacto dos níveis de troponina na indicação de estratégia invasiva e revascularização miocárdica. Métodos Estudo de corte transversal de pacientes com SCA com avaliação do pico da troponina I, escores de risco, análise prospectiva de desfechos clínicos até 30 dias e testes bilaterais de significância, com nível de significância adotado sendo < 0,05. Resultados Foram avaliados 494 pacientes com SCA. Troponina > percentil 99 e abaixo do ponto de corte, assim como valores maiores (acima do ponto de corte), foram associados à maior incidência do desfecho composto (p<0,01) e de revascularização percutânea ou cirúrgica (p<0,01), sem diferença significante em mortalidade até 30 dias. Conclusões Valores de troponina elevados acima do percentil 99 pela Definição Universal de IAM apresentam papel prognóstico e agregam informação útil ao diagnóstico clínico e escores de risco na identificação de pacientes com maior probabilidade de benefício com estratificação invasiva e procedimentos de revascularização coronária.

Abstract Background Contemporary diagnosis of ACS and risk stratification are essential for appropriate management and reduction of mortality and recurrent ischemic events, in the acute phase of disease and after hospitalization. The Universal Definition of Myocardial Infarction recommends the detection of troponin levels above the 99th percentile. Objectives To evaluate the occurrence of early death and acute myocardial infarction (AMI) in patients without elevation of troponin (<0.034 ng/mL), patients with mild elevation (above the 99th percentile [>0.034 ng/mL and <0.12 ng/mL)], and patients with significant elevation of troponin (above the diagnostic cutoff for AMI defined by the troponin kit (≥0.12 ng/mL)]; and to analyze the impact of troponin on the indication for invasive strategy and myocardial revascularization. Methods Cross-sectional cohort study of patients with ACS with assessment of peak troponin I, risk score, prospective analysis of 30-day clinical outcomes and two-sided statistical tests, with statistical significance set at p<0.05. Results A total of 494 patients with ACS were evaluated. Troponin > 99th percentile and below the cutoff point, as well as values above the cutoff, were associated with higher incidence of composite endpoint (p<0.01) and higher rates of percutaneous or surgical revascularization procedures (p<0.01), without significative difference in 30-day mortality. Conclusions Troponin levels above the 99th percentile defined by the universal definition of AMI play a prognostic role and add useful information to the clinical diagnosis and risk scores by identifying those patients who would most benefit from invasive risk stratification and coronary revascularization procedures.

Abstract Some conditions consolidated as risk factors for oropharyngeal dysphagia have already been identified in other diseases, such as neurological. Studies on cardiovascular diseases concentrate in individuals in the postoperative period; thus, it is unknown if these same factors occur in individuals hospitalized for clinical or surgical treatment of these diseases. Objective to correlate predictive risk factors for oropharyngeal dysphagia in individuals with cardiovascular disease admitted at a reference cardiology hospital. Methodology This is a retrospective clinical study. Medical records of 175 individuals hospitalized for clinical and/or surgical treatment at a reference cardiology hospital from January to June 2017, attendants of the Speech-Language Pathology and Nutrition team, were analyzed. Of these, 100 records were included in the study: 41 females and 59 males (mean age 67.56 years). Deaths and individuals from 0 to 18 years were excluded. Stroke, malnutrition, age and prolonged orotracheal intubation were considered predictive risk factors for oropharyngeal dysphagia. Mann-Whitney test and Fisher's test were used for statistical analysis. Results Stroke (OR=2.93 p=0.02), malnutrition (OR=2.89 p=0.02) and prolonged orotracheal intubation (OR=3.94 p=0.02) were statistically significant predictors for oropharyngeal dysphagia within this population. Age below 80 years was not significant (p=0.06), but within octogenarians, significance was found (p=0.033). Conclusion Stroke, malnutrition, prolonged orotracheal intubation and age > 80 years are predictive risk factors for oropharyngeal dysphagia in adult population with cardiovascular diseases.

RESUMO FUNDAMENTAÇÃO: Não há fortes evidências sobre a associação entre o perfil inflamatório e o padrão de resposta ao tratamento medicamentoso em pacientes depressivos que podem resultar em ocorrência de doença coronariana. OBJETIVO: O objetivo deste estudo foi comparar os marcadores de aterosclerose subclínica, o perfil inflamatório e a produção de BDNF em pacientes com Depressão Resistente (DR) ou Transtorno Afetivo Bipolar (BAD) sob tratamento convencional. MÉTODOS: A população avaliada incluiu 34 RD, 43 BAD e 41 controles. Os marcadores de aterosclerose subclínica foram avaliados por ultrassonografia, tomografia e teste de esforço. As concentrações plasmáticas de TNFα, IL-1β, IL-6 e BDNF foram medidas utilizando Luminex100TM. A concentração de usCRP foi medida por imunoensaio turbidimétrico. A expressão de IL1B, IL6 e TNFA foi determinada usando TaqMan®. Para as análises estatísticas, foi estabelecido o nível de significância de p < 0,05. RESULTADOS: Quanto aos marcadores de aterosclerose subclínica, apenas o consumo de O2 foi reduzido no grupo BAD (p = 0,001). Embora não tenham sido encontradas diferenças na expressão gênica, a concentração plasmática de BDNF e IL-1β foi aumentada no grupo RD (p = 0,002 e p = 0,005, respectivamente) mesmo sob tratamento antidepressivo, o que sugere que esses medicamentos não têm efeito na secreção de IL-1β e que o inflamassomo pode desempenhar um papel na resposta terapêutica. CONCLUSÃO: Juntas, as concentrações BDNF e IL-1β poderiam ser usadas para a identificação precoce de pacientes com DR.

SUMMARY BACKGROUND: There is no strong evidence on the link between inflammatory profile and pattern of drug treatment response in depressive patients that could result in Coronary Artery Disease occurrence. OBJECTIVE: This study aimed to compare the subclinical atherosclerosis markers, inflammatory profile, and BDNF production in Resistant Depression (RD) or Bipolar Affective Disorder (BAD) patients under conventional treatment. METHODS: The population evaluated was comprised of 34 RD, 43 BAD, and 41 controls. Subclinical atherosclerosis markers were evaluated using ultrasonography, tomography, and exercise stress test. Plasma concentrations of TNFα, IL-1β, IL-6, and BDNF were measured using Luminex100™. The usCRP concentration was measured using turbidimetric immunoassay. IL1B, IL6, and TNFA expression were determined using TaqMan®. For the statistical analysis, the significance level was established at p<0.05. RESULTS: Concerning subclinical atherosclerosis markers, only O2 consumption was reduced in the BAD group (p = 0.001). Although no differences were found in gene expression, BDNF and IL-1β plasma concentration was increased in the RD group (p = 0.002 and p = 0.005, respectively) even with an antidepressant treatment, which suggests that these drugs have no effect in IL-1β secretion and that the inflammasome may play a role in therapy response. CONCLUSION: Taken together, both BDNF and IL-1β plasma concentrations could be used to the early identification of RD patients.

No GII 13,3% apresentaram disfagia leve, 33,3% moderada e 53,33% grave. Verificou-se associação linear significante entre o grau de disfagia e o tempo de IOT (p= 0,031), indicando que o número de indivíduos com disfagia moderada e grave foi maior no grupo com mais tempo de intubaçao.CONCLUSÕES:constatou-se que o tempo de intubação orotraqueal maior que 24 horas aumentou o grau da disfagia orofaríngea nesta população.

PURPOSE: to associate the degree of oropharyngeal dysphagia and orotracheal intubation time in post stroke individuals after cardiac surgery.METHODS: a cross-sectional retrospective descriptive clinical study carried out by means of protocols data collection and chart records during six months in a public hospital of reference in cardiology. We analyzed 25 protocols and medical records of individuals undergoing cardiac surgery who evolved with stroke and were assisted by a team of speech and language pathology. The subjects were divided into two groups. Group I (GI) consisted of 10 individuals with orotracheal intubation less than 24 hours and Group II (GII) of 15 individuals with orotracheal intubation more than 24 hours. After performing swallowing clinical evaluation and analyzing the association between the clinical classification of degree of commitment for dysphagia and orotracheal intubation time.RESULTS: it was found that 40% of the individuals in GI presented mild dysphagia, 30% moderate and 20% severe. In GII, 13.3 % presented mild dysphagia, 33.3% moderate and 53.33% severe. There was a significant linear association between the degree of dysphagia and the duration of intubation (p = 0.031), indicating that the number of individuals with moderate and severe dysphagia was higher in the group with a longer intubation.CONCLUSIONS: we could observe that time of orotracheal intubation more than 24 hours increases the degree of oropharyngeal dysphagia in this population.

FUNDAMENTO: O tecido adiposo representa não somente uma fonte de energia estocável, mas principalmente um órgão endócrino que secreta várias citoquinas. A adiponectina, uma nova proteína semelhante ao colágeno, foi descoberta como uma citoquina específica do adipócito e um promissor marcador de risco cardiovascular. OBJETIVO: Avaliar a associação entre os níveis séricos da adiponectina e o risco para a ocorrência de eventos cardiovasculares, em pacientes com síndromes coronarianas agudas (SCA), e as correlações entre adiponectina e os biomarcadores metabólicos, inflamatórios e miocárdicos. MÉTODOS: Foram recrutados 114 pacientes com SCA, com seguimento médio de 1,13 ano para avaliação de desfechos clínicos. Modelos de regressão de risco proporcional de Cox com penalização de Firth foram construídos para determinar a associação independente entre adiponectina e o risco subsequente dos desfechos primário (composto de óbito cardiovascular/IAM não fatal/AVE não fatal) e coprimário (composto de óbito cardiovascular/ IAM não fatal/AVE não fatal/re-hospitalização requerendo revascularização). RESULTADOS: Houve correlações diretas e significantes entre adiponectina e idade, HDL-colesterol e BNP, e inversas e significantes entre adiponectina e circunferência abdominal, peso corporal, índice de massa corporal, índice HOMA, triglicerídeos e insulina. A adiponectina foi associada a maior risco para os desfechos primário e coprimário (HR ajustado 1,08 e 1,07/incremento de 1.000, respectivamente, p = 0,01 e p = 0,02). CONCLUSÃO: Em pacientes com SCA, a adiponectina sérica foi preditor de risco independente para eventos cardiovasculares. De modo adicional às correlações antropométricas e metabólicas, a adiponectina mostrou correlação significante com BNP.

BACKGROUND: The adipose tissue is considered not only a storable energy source, but mainly an endocrine organ that secretes several cytokines. Adiponectin, a novel protein similar to collagen, has been found to be an adipocyte-specific cytokine and a promising cardiovascular risk marker. OBJECTIVES: To evaluate the association between serum adiponectin levels and the risk for cardiovascular events in patients with acute coronary syndromes (ACS), as well as the correlations between adiponectin and metabolic, inflammatory, and myocardial biomarkers. METHODS: We recruited 114 patients with ACS and a mean 1.13-year follow-up to measure clinical outcomes. Clinical characteristics and biomarkers were compared according to adiponectin quartiles. Cox proportional hazard regression models with Firth's penalization were applied to assess the independent association between adiponectin and the subsequent risk for both primary (composite of cardiovascular death/non-fatal acute myocardial infarction (AMI)/non-fatal stroke) and co-primary outcomes (composite of cardiovascular death/non-fatal AMI/non-fatal stroke/rehospitalization requiring revascularization). RESULTS: There were significant direct correlations between adiponectin and age, HDL-cholesterol, and B-type natriuretic peptide (BNP), and significant inverse correlations between adiponectin and waist circumference, body weight, body mass index, Homeostasis Model Assessment (HOMA) index, triglycerides, and insulin. Adiponectin was associated with higher risk for primary and co-primary outcomes (adjusted HR 1.08 and 1.07/increment of 1000; p = 0.01 and p = 0.02, respectively). CONCLUSION: In ACS patients, serum adiponectin was an independent predictor of cardiovascular events. In addition to the anthropometric and metabolic correlations, there was a significant direct correlation between adiponectin and BNP.

FUNDAMENTO: Cerca de 30% dos AVE perioperatórios da cirurgia de revascularização do miocárdio (CRM) são decorrentes de lesões carotídeas, sem redução de risco confirmada por intervenção perioperatória. OBJETIVOS: Avaliar o impacto da doença carotídea e a intervenção perioperatória nos pacientes submetidos à CRM. MÉTODOS: Estudo retrospectivo observacional, avaliando 1.169 pacientes com idade > 65 anos submetidos à CRM entre janeiro de 2006 e dezembro de 2010, acompanhados, em média, por 49 meses. Todos foram submetidos à ultrassonografia de carótidas prévia à CRM. Definiu-se doença carotídea quando lesão > 50%. O desfecho primário foi composto pela incidência de AVE, acidente isquêmico transitório (AIT) e óbito por AVE. RESULTADOS: A prevalência da doença carotídea foi de 19,9% dos pacientes. A incidência do desfecho primário entre portadores e não portadores foi de 6,5% e 3,7%, respectivamente (p = 0,0018). Nos primeiros 30 dias, ocorreram 18,2% dos eventos. Relacionaram-se a doença carotídea: disfunção renal (OR 2,03, IC95% 1,34-3,07; p < 0,01), doença arterial periférica (OR 1,80, IC95% 1,22-2,65; p < 0,01) e infarto do miocárdio prévio (OR 0,47, IC95% 0,35-0,65; p < 0,01). Quanto ao desfecho primário, foram associados AIT prévio (OR 5,66, IC95% 1,67-6,35; p < 0,01) e disfunção renal (OR 3,28, IC95% 1,67-6,45; p < 0,01). Nos pacientes com lesão > 70%, a intervenção carotídea perioperatória apresentou incidência de 17% no desfecho primário contra 4,3% na conduta conservadora (p = 0,056) sem diferença entre abordagens percutânea e cirúrgica (p = 0,516). CONCLUSÃO: A doença carotídea aumenta o risco para AVE, AIT ou morte por AVE na CRM. Entretanto, a intervenção carotídea não foi relacionada à redução do desfecho primário.

BACKGROUND: Approximately 30% of perioperative CVA of myocardial revascularization surgery (MRS) are a result of carotid injuries, without reduction of risk confirmed by perioperative intervention. OBJECTIVES: Evaluate the impact of carotid disease and perioperative intervention in patients subjected to MRS. METHODS: Observational, retrospective study, evaluating 1169 patients aged > 69 years undergoing MRS from January, 2006 and December, 2010, monitored, on average, for 49 months. All patients were subjected to ultrasonography of carotids before MRS. It was defined as carotid disease when lesion > 50%. The primary outcome was composed of CVA incidence, transitory ischemic accident (TIA) and death due CVA. RESULTS: Prevalence of carotid disease was of 19.9% of patients. The incidence of primary outcome between unhealthy and healthy patients was of 6.5% and 3.7%, respectively (p = 0.0018). In the first 30 days, there were 18.2% of events. Were related to carotid disease: renal dysfunction (OR 2.03, IC95% 1.34-3.07; p < 0.01), peripheral arterial disease (OR 1.80, IC95% 1.22-2.65; p < 0.01) and previous myocardial infarction (OR 0.47, IC95% 0.35-0.65; p < 0.01). Regarding the primary outcome, were associated the previous TIA (OR 5.66, IC95% 1.67-6.35; p < 0.01) and renal dysfunction (OR 3.28, IC95% 1.67-6.45; p < 0.01). In patients with lesion >70%, perioperative carotid intervention demonstrated an incidence of 16% in primary outcome compared to 4.3% in conservatory treatment (p = 0.056) with no difference between percutaneous and surgical approaches (p = 0.516). CONCLUSION: Carotid disease increases the risk of CVA, TIA or death due to CVA in MRS. However, the carotid intervention was not related to reduction of primary outcome.

OBJECTIVES: Progression of hepatic fibrosis is accelerated in patients co-infected with human immunodeficiency virus and hepatitis C virus compared to hepatitis C virus mono-infected patients. This study aimed to compare ultrasound features and selected clinical and biochemical variables between patients with human immunodeficiency virus/hepatitis C virus co-infection (n = 16) versus hepatitis C virus mono-infection (n = 16). METHODS: Each patient underwent abdominal ultrasound, and a specific evaluation was performed in order to detect findings consistent with chronic liver disease. Characterization of spleen size, liver structural pattern, diameter of the portal, spleen, and mesenteric veins was based on classical ultrasound parameters. Propensity score was used for control of selection bias and performed using binary logistic regression to generate a score for each patient. The Fisher and Mann-Whitney tests were used to evaluate categorical variables and continuous variables, respectively. RESULTS: On univariate analysis right hepatic lobe size was larger in human immunodeficiency virus/hepatitis C virus patients (157.06 ± 17.56 mm) compared to hepatitis C virus mono-infected patients (134.94 ± 16.95 mm) (p = 0.0011). The left hepatic lobe was also significantly larger in human immunodeficiency virus/hepatitis C virus patients Cirrhosis (115.88 ±22.69 mm) versus hepatitis C virus mono-infected patients (95.06 ±24.18 mm) (p= 0.0177). Also, there was a strong correlation between hepatomegaly and co-infection (p=0.005). CONCLUSION: Human immunodeficiency virus infection was the primary variable influencing liver enlargement in this population. Hepatomegaly on ultrasound was more common among cirrhotic human immunodeficiency virus/hepatitis C virus co-infected patients than among cirrhotic hepatitis C virus mono-infected patients. This aspect is very important in the management of human immunodeficiency virus/hepatitis C virus co-infected patients, because screening for hepatocellular carcinoma is necessary in this population.

OBJETIVOS: Determinar a importância das variáveis: Intensidade de Energia (I), Potência (P) e Tempo de Aplicação (T) nas alterações histológicas ocorridas em varizes de membros inferiores submetidas à eletrocauterização endovascular. MÉTODO: Estudo prospectivo experimental realizado em pacientes submetidos à eletrocauterização endovenosa de fragmento proximal da veia safena magna, de acordo com uma tabela de aleatorização - GI: I=0J, P=0W, T=15s; GII: I=300J, P=60W, T=5s; GIII: I=600J, P=60W, T=10s; GIV: I=900J, P=60W, T=15s; GV: I=450J, P=90W, T=5s; GVI: I=900J, P=90W, T=10s; GVII: I=1350J, P=90W, T=15s; GVIII: I=600J, P=120W, T=5s; GIX: I=1200J, P=120W, T=10s; GX: I=1800J, P=120W, T=15s. Os fragmentos foram submetidos a estudo anatomopatológico com o objetivo de analisar a profundidade das alterações tissulares, assim classificadas: Grupo A - endotélio e média, Grupo B - endotélio, média e adventícia. RESULTADOS: A intensidade das alterações histológicas - Grupo A e B - ocorridas nos fragmentos foram proporcionais à Intensidade de Energia de eletrocauterização (p=0,0001). Essa associação linear também pode ser verificada para as variáveis Potência (p=0,017) e Tempo de Aplicação (p=0,0001). O índice de correlação de Spearman foi maior para variável Tempo de Aplicação: 0,42269 (p=0,002) quando comparada com a variável Potência de Energia: 0,3542 (p=0,005). CONCLUSÃO: O Tempo de Aplicação de Energia é mais importante do que a Potência de Energia utilizada para uma mesma energia de eletrocauterização, na determinação da profundidade dos efeitos histológicos observados na parede das varizes de membros inferiores.

OBJECTIVE: To determine the importance of the variables: Energy Intensity (I), Power (P) and Time of Application (T) in the histological changes occurring in lower limb varicose vein submitted to endovascular electrocauterization. METHOD: Prospective experimental study conducted in patients undergoing great saphenous vein electrocauterization according to a randomization table - GI: I=0J, P=0W, T=15s; GII: I=300J, P=60W, T=5s; GIII: I=600, P=60W, T=10s; GIV: I=900J, P=60W, T=15s; GV: I=450J, P=90W, T=5s; GVI: I=900J, P=90W, T=10s; GVII: I=1350W, P=90W, T=15s; GVIII: I=600, P=120W, T=5s; GIX: I=1200J, P=120W, T=10s; GX: I=1800J, P=120W, T=15s. The fragments were submitted to histopathological examination in order to analyze the depth of tissue changes, classified as follows: Group A - endothelium and media; Group B - endothelium, media and adventitia. RESULTS: The intensity of histological changes - Groups A and B - that occur in the fragments were proportional to Energy Intensity of electrocauterization (p=0.0001), Power (p=0.017) and Time of Application (p=0.0001). The Spearman correlation coefficient was more powerful for the variable Time of Application: 0.42269 (p=0.002) when compared with the variable Power of Energy (P): 0.3542 (p=0.005). CONCLUSION: Time of Application of Energy is a stronger predictor than the Power of Energy in determining the depth of the histological effects observed in the wall of the varicose vein submitted to electrocauterization.
