The beneficial effects of Elabela on the cardiovascular system have been shown in studies.To compare serum Elabela levels of chronic total occlusion (CTO) patients with control patients with normal coronary arteries, and to investigate whether there is a correlation with collateral development.The study was planned cross-sectionally and prospectively. Fifty patients (28.0% female, mean age 61.6±7.3years) with CTO in at least one coronary vessel and 50 patients (38% female, mean age 60,7±6.38 years) with normal coronary arteries were included in the study. Patients in the CTO group were divided into two groups as Rentrop 0-1, those with weak collateral development, and Rentrop 2-3 with good collateral development. In addition to the age, sex, demographic characteristics and routine laboratory tests of the patients, Elabela levels were measured.Demographic characteristics and laboratory values were similar in both groups. While the mean NT-proBNP and troponin were higher in the CTO group, the Elabela mean was lower (p0.05 for all). In the multivariate regression analysis, NT-proBNP and Elabela levels were found to be independent predictors for CTO. Also, Elabela level was found to be statistically higher in Rentrop class 2-3 patients compared to Rentrop class 0-1 patients (p0.05).In our study, we showed that the average Elabela level was low in CTO patients compared to normal patients. In addition, we found the level of Elabela to be lower in patients with weak collateral development compared to patients with good collateral development. (Arq Bras Cardiol. 2021; [online].ahead print, PP.0-0).Os efeitos benéficos do elabela no sistema cardiovascular foram demonstrados em estudos.Comparar os níveis séricos de elabela de pacientes com oclusão total crônica (OTC) com pacientes controle com artérias coronárias normais e investigar se há correlação com o desenvolvimento colateral.Estudo transversal e prospectivo. O estudo incluiu cinquenta pacientes (28,0% mulheres, idade média 61,6±7,3 anos) com OTC em pelo menos um vaso coronário e 50 pacientes (38% mulheres, idade média 60,7±6,38 anos) com artérias coronárias normais. Os pacientes do grupo OTC foram divididos em dois grupos: Rentrop 0–1, composto por pacientes com fraco desenvolvimento colateral e Rentrop 2–3, composto por pacientes com bom desenvolvimento colateral. Além da idade, sexo, características demográficas e exames laboratoriais de rotina dos pacientes, foram medidos os níveis de elabela.As características demográficas e os valores laboratoriais mostraram-se semelhantes em ambos os grupos. Ao passo que o nível médio de NT-proBNP e troponina estava maior no grupo OTC, o nível médio de elabela estava menor (p0,05 para todos). Na análise de regressão multivariada, os níveis de NT-proBNP e elabela foram considerados preditores independentes para OTC. Além disso, o nível de elabela apresentou-se estatisticamente maior em pacientes do grupo Rentrop 2–3 em comparação com os pacientes do grupo Rentrop 0–1 (p0,05).Em nosso estudo, mostramos que o nível médio de elabela estava baixo em pacientes com OTC em comparação com pacientes normais. Além disso, constatamos que o nível de elabela é inferior em pacientes com desenvolvimento colateral fraco em comparação com pacientes com bom desenvolvimento colateral.

Resumo Fundamento De acordo com o pensamento diagnóstico tradicional, indivíduos muito idosos estão mais predispostos a desenvolver sintomas atípicos em síndromes coronarianas agudas. Objetivo Testar a hipótese de que indivíduos muito idosos estão mais predispostos a manifestações de dor torácica atípica devido à doença arterial coronariana obstrutiva (DAC). Métodos O Registro de dor torácica inclui pacientes internados com dor torácica aguda. Primeiramente, foi construído o índice de tipicidade dessa manifestação clínica: a soma de 12 características de sintomas (8 sintomas típicos e 4 sintomas atípicos). No subgrupo de pacientes com etiologia coronariana, o índice de tipicidade foi comparado entre octogenários e não octogenários. A significância estatística foi definida por p

Background Cangrelor, an intravenous, reversible P2Y12 antagonist, is approved for use in patients undergoing percutaneous coronary intervention (PCI). Objectives This study sought to evaluate the efficacy and safety of cangrelor compared with clopidogrel in subgroups that did and did not receive glycoprotein IIb/IIIa inhibitors (GPIs). Methods This pooled, patient-level analysis of the 3 CHAMPION (Cangrelor versus Standard Therapy to Achieve Optimal Management of Platelet Inhibition) trials analyzed all randomized patients who underwent PCI and received the study drug (n = 24,902). Only bailout/rescue GPI use was permitted, except in CHAMPION PCI, in which routine or bailout/rescue GPI use was at the site investigator’s discretion. The primary efficacy endpoint was the composite of all-cause mortality, myocardial infarction, ischemia-driven revascularization, or stent thrombosis at 48 h after randomization. Results Overall, 3,173 patients (12.7%) received a GPI, most commonly eptifibatide (69.4%). Despite variation in indications for GPIs, baseline characteristics were well balanced between the cangrelor and clopidogrel arms in subsets receiving and not receiving GPIs. Rates of the primary composite endpoint were lower with cangrelor compared with clopidogrel in patients who did (4.9% vs. 6.5%; odds ratio [OR]: 0.74; 95% confidence interval [CI]: 0.55 to 1.01) or did not receive a GPI (3.6% vs. 4.4%; OR: 0.82; 95% CI: 0.72 to 0.94; Pint = 0.55). Cangrelor did not increase the primary safety endpoint, GUSTO-defined severe/life-threatening bleeding, in patients who did (0.4% vs. 0.5%; OR: 0.71; 95% CI: 0.25 to 1.99) or did not receive GPIs (0.2% vs. 0.1%; OR: 1.56; 95% CI: 0.80 to 3.04; Pint = 0.21). GPI use was associated with increased risk of bleeding in both treatment arms. Conclusions Cangrelor’s efficacy in reducing ischemic complications in patients undergoing PCI was maintained irrespective of GPI administration. GPI use was associated with substantially higher bleeding rates, regardless of the randomization to cangrelor or clopidogrel.

The management of stage I seminoma has evolved over the past 20 years. Contemporary management options after orchiectomy include adjuvant radiation, adjuvant chemotherapy, and observation. This analysis defines the experience at Kaiser Permanente Southern California from 1990 to 2010. We examined outcomes for stage I seminoma patients and reviewed prognostic factors for recurrence in those managed with observation.This is a retrospective study of 502 stage I seminoma patients who underwent orchiectomy from 1990 to 2010. Outcomes examined were relapse-free survival (RFS), overall survival (OS), and cause-specific survival (CSS). Risk factors for recurrence evaluated were age, preoperative hCG elevation, preoperative LDH elevation, tumor size, lymphovascular invasion, rete testis invasion, epididymis invasion, and invasion through the tunica albuginea.Among radiation patients, 5-year RFS was 97.2%, OS was 98.0%, and CSS was 99.3%. Among chemotherapy patients, 2-year RFS was 98.3% and OS and CSS were 100%. Among observation patients, 5-year RFS was 89.2%, OS was 98.8%, and CSS was 100%. There was no difference in OS or CSS among the groups. RFS was significantly lower for observation patients. Among observation patients, univariate analysis identified tumor size, lymphovascular invasion, and rete testis invasion as risk factors for relapse. No factors were significant on multivariate analysis.Our data show that adjuvant radiation and chemotherapy yield similar outcomes in the management of stage I seminoma. Observation results in a lower RFS, but patients who relapse can be salvaged; OS and CSS are not affected.

Introduction: Cardiac allograft vasculopathy (CAV) is a major limitation for long-term survival of patients undergoing heart transplantation (HT). Some immunosuppressants can reduce the risk of CAV. Objectives: The primary objective was to evaluate the variation in the volumetric growth of the intimal layer measured by intracoronary ultrasound (IVUS) after 1 year in patients who received basiliximab compared with that in a control group. Methods: Thirteen patients treated at a single center between 2007 and 2009 were analyzed retrospectively. Evaluations were performed with IVUS, measuring the volume of a coronary segment within the first 30 days and 1 year after HT. Vasculopathy was characterized by the volume of the intima of the vessel. Results: Thirteen patients included (7 in the basiliximab group and 6 in the control group). On IVUS assessment, the control group was found to have greater vessel volume (120–185.43 mm3 vs. 127.77–131.32 mm3; p = 0.051). Intimal layer growth (i.e., CAV) was also higher in the control group (27.30–49.15 mm3 [∆80%] vs. 20.23–26.69 mm3 [∆33%]; p = 0.015). Univariate regression analysis revealed that plaque volume and prior atherosclerosis of the donor were not related to intima growth (r = 0.15, p = 0.96), whereas positive remodeling was directly proportional to the volumetric growth of the intima (r = 0.85, p < 0.001). Conclusion: Routine induction therapy with basiliximab was associated with reduced growth of the intima of the vessel during the first year after HT. Resumo Fundamento: A doença vascular do enxerto (DVE) constitui uma grande limitação de sobrevida a longo prazo de pacientes submetidos a transplante cardíaco (TxC). Alguns imunossupressores diminuem o aparecimento da DVE. Objetivos: O principal objetivo foi avaliar, através de ultrassonografia intracoronária (USIC), a variação do crescimento volumétrico da camada íntima e comparar, após um ano, o grupo que recebeu basiliximab com um grupo de controle. Métodos: Treze pacientes de um único centro foram analisados retrospectivamente de 2007 a 2009. As análises foram feitas através de USIC, medindo-se o volume de um segmento coronariano nos primeiros 30 dias e um ano após o TxC. A vasculopatia foi caracterizada pelo volume da camada íntima do vaso. Resultados: O estudo incluiu 13 pacientes (7 no grupo com o basiliximab e 6 no grupo de controle). A análise por USIC revelou que o grupo de controle apresentou maior crescimento volumétrico do vaso (131,32 a 127,77 mm3 x 120 a 185,43 mm3 p = 0,051). O crescimento da camada íntima (CCI) também foi maior no grupo de controle [Basiliximab: 20,23 a 26,69 mm3 (∆ 33%); Controle: 27,30 a 49,15 mm3 (∆ 80% p = 0,015)]. De acordo com a regressão univariada, o volume da placa aterosclerótica prévia do doador não teve relação com o crescimento da íntima (r = 0,15, p = 0,96), enquanto que o remodelamento positivo do vaso foi diretamente proporcional ao crescimento da íntima (r = 0,85, p < 0,001). Conclusão: A terapia de indução de rotina com basiliximab está associada à redução do crescimento da camada íntima do vaso no primeiro ano após o transplante cardíaco.

Background: The recommendations in guidelines are based on evidence; however, there is a gap between recommendations and clinical practice. Objective: To describe the practice of prescribing evidence-based treatments for patients with acute coronary syndrome in Brazil. Methods: This study carried out a subanalysis of the ACCEPT registry, assessing epidemiological data and the prescription rate of acetylsalicylic acid, p2y12 inhibitors, antithrombotic drugs, beta-blockers, angiotensin-converting enzyme inhibitors/angiotensin-receptor blockers (IAT1RB), and statins. In addition, the quality of myocardial reperfusion in ST-segment elevation myocardial infarction was evaluated. Results: This study assessed 2,453 patients. The prescription rates of acetylsalicylic acid, p2y12 inhibitors, antithrombotic drugs, beta-blockers, angiotensin-converting enzyme inhibitors/IAT1RB, and statins were as follows: in 24 hours - 97.6%, 89.5%, 89.1%, 80.2%, 67.9% and 90.6%; and at six months - 89.3%, 53.6%, 0%, 74.4%, 57.6% and 85.4%, respectively. Regarding ST-segment elevation myocardial infarction, only 35.9% and 25.3% of the patients underwent primary angioplasty and thrombolysis, respectively, within the recommended times. Conclusion: This registry showed high initial prescription rates of antiplatelet drugs, antithrombotic drugs, and statins, and lower prescription rates of beta-blockers and angiotensin-converting enzyme inhibitors/IAT1RB. Independently of the class, the use of all drugs decreased by six months. Most patients with ST-segment elevation myocardial infarction did not undergo myocardial reperfusion within the time recommended.

Cardiac transplantation continues to be the treatment of choice for heart failure refractory to optimized treatment. Two methods have high sensitivity for diagnosing allograft rejection episodes and cardiac allograft vasculopathy (CAV), important causes of mortality after transplantation.To assess the relationship between intravascular ultrasound (IVUS) results and endomyocardial biopsy (BX) reports in the follow-up of patients undergoing cardiac transplantation in a Brazilian reference service.A retrospective epidemiological observational study was carried out with patients undergoing orthotopic cardiac transplantation from 2000 to 2009. The study assessed the medical records of those patients and the results of the IVUS and BX routinely performed in the clinical post-transplant follow-up, as well as the therapy used.Of the 77 patients assessed, 63.63% were males, their ages ranging from 22 to 69 years. Regarding the IVUS results, 33.96% of the patients were classified as Stanford class I, and 32.08%, as Stanford class IV. Of the 143 BX reports, 51.08% were 1R, and 0.69%, 3R. The Quilty effect was described in 14.48% of the BX reports. All patients used antiproliferative agents, 80.51% used calcineurin inhibitors, and 19.48% used proliferation signal inhibitors.The assessment of cardiac transplant patients by use of IVUS provides detailed information for the early and sensitive diagnosis of CAV, which is complemented by histological data derived from BX, establishing a possible causal relationship between CAV and humoral rejection episodes.

Purpose To report our experience in treating T3 and T4 anal carcinoma with combined external beam (EBRT) and chemotherapy, followed by interstitial 192Ir implant boost. Methods and Materials From 1990 to 2000, 31 patients with T3 and T4 anal carcinoma were treated with: 30 Gy EBRT (2 Gy fractions, 5 days/week) + 5-fluorouracil + mitomycin-C. Median implant dose was 31.3 Gy at 0.5 cm, delivered at a mean rate of 0.52 Gy/h. Results Six patients had local persistence and 4 eventually developed local-regional recurrence. Eight underwent abdomino-perineal resection (APR). With the addition of APR in selected cases, the ultimate local-regional control after initial treatment was 84%. Distant metastases occurred in 10. Of the initial cohort, 55% is still alive and NED. Eight had radiation proctitis and 7 developed postimplant ulceration. Only 1 required surgical intervention. Conclusions Treatment of T3 and T4 anal cancer with combined chemotherapy and EBRT, followed by interstitial implant results in an ultimate local-regional control of 84%, after the inclusion of selected APR. It is well tolerated, with acceptable toxicity.

Purpose Management of squamous cell carcinoma of undetermined primary tumors in the head and neck region is controversial. Here we report the Southern California Kaiser Permanente experience with these patients. Methods and Materials From January 1969 through December 1994, 106 patients were eligible for this retrospective analysis. Distribution of nodal staging was as follows: 14 N1, 27 N2A, 39 N2B, 2 N2C, and 24 N3. Initial treatment included excisional biopsy alone in 12, radical neck dissection alone in 29, radiotherapy alone in 24, excisional biopsy followed by radiotherapy in 15, and radical neck dissection plus postoperative radiation in 26 patients. Results Except for two patients, all patients have had a minimum follow-up of 5 years. Overall, 57 patients (54%) have had recurrences. Only two patients (3%) who had received radiotherapy as part of their initial treatment had an appearance of a potential primary site inside the irradiated field vs 13 patients (32%) who had not received radiotherapy (p = .006). Combined modality therapy resulted in fewer neck relapses, particularly in patients with advanced neck disease. Including salvage, surgery alone as the initial treatment resulted in 81% ultimate tumor control above the clavicle for patients with N1 and N2a disease without extracapsular extension. The 5-year survival for the entire population was 53%. Radiotherapy alone resulted in poor survival in patients with advanced/unresectable neck disease. No significant difference in survival based on the initial treatment was found. The statistically significant adverse factors in determining survival included advanced nodal stage and the presence of extracapsular extension. Conclusions Radiotherapy is very effective in reducing the rate of appearance of a potential primary site. However, in the absence of advanced neck disease (N1 and N2A without extracapsular extension), radiotherapy can be reserved for salvage. Radiotherapy alone results in poor outcomes in patients with advanced/unresectable neck disease, and incorporation of concurrent chemotherapy and cytoprotective agents should be investigated. © 2002 Wiley Periodicals, Inc.
