Comportamento da síndrome coronariana aguda: resultados de um registro brasileiro

FUNDAMENTO: O Brasil carece de registros multicêntricos publicados de síndrome coronariana aguda. OBJETIVO: O Registro Brasileiro de Síndrome Coronariana Aguda é um estudo multicêntrico nacional com objetivo de apresentar dados representativos das características clínicas, e manejo e evolução hospitalares dessa síndrome. MÉTODOS: Participaram 23 hospitais de 14 cidades. Foram elegíveis pacientes que se apresentaram com suspeita de síndrome coronariana aguda nas primeiras 24 horas, com quadro clínico sugestivo, associado a alterações eletrocardiográficas compatíveis e/ou marcadores de necrose. O seguimento foi realizado até o óbito ou a alta hospitalar. RESULTADOS: Entre os anos de 2003 e 2008, foram incluídos 2.693 pacientes com diagnóstico de síndrome coronariana aguda, sendo 864 (32,1%) mulheres. O diagnóstico final foi de angina instável para 1.141 (42,4%) pacientes, com mortalidade de 3,06% deles; de infarto agudo do miocárdio sem supradesnível de ST para 529 (19,6%) pacientes, com mortalidade de 6,8% deles; e de infarto agudo do miocárdio com supradesnível de ST para 950 (35,3%) pacientes, com mortalidade de 8,1% deles; tiveram diagnóstico não confirmado 73 (2,7%) pacientes, com mortalidade de 1,36% deles. A mortalidade global foi de 5,53%. O modelo de regressão logística múltipla identificou o gênero feminino (OR=1,45), o diabetes melito (OR=1,59), o índice de massa corporal (OR=1,27) e a intervenção coronariana percutânea (OR=0,70) como fatores de risco de óbito, para demografia e intervenções. Um modelo para óbito por complicações maiores identificou choque cardiogênico/Edema Agudo de Pulmão (OR=4,57), reinfarto (OR=3,48), acidente vascular cerebral (OR=21,56), sangramento grave (OR=3,33), parada cardiorrespiratória (OR=40,27) e classe funcional de Killip (OR=3,37). CONCLUSÃO: Os dados do Registro Brasileiro de Síndrome Coronariana Aguda não diferem de outros coletados fora do país. Seus achados poderão ajudar a promover um melhor planejamento e manejo do atendimento da síndrome coronariana aguda a nível público e privado.

Assessing Strategies for Heart Failure with Preserved Ejection Fraction at the Outpatient Clinic

Background: Heart failure with preserved ejection fraction (HFPEF) is the most common form of heart failure (HF), its diagnosis being a challenge to the outpatient clinic practice. Objective: To describe and compare two strategies derived from algorithms of the European Society of Cardiology Diastology Guidelines for the diagnosis of HFPEF. Methods: Cross-sectional study with 166 consecutive ambulatory patients (67.9±11.7 years; 72% of women). The strategies to confirm HFPEF were established according to the European Society of Cardiology Diastology Guidelines criteria. In strategy 1 (S1), tissue Doppler echocardiography (TDE) and electrocardiography (ECG) were used; in strategy 2 (S2), B-type natriuretic peptide (BNP) measurement was included. Results: In S1, patients were divided into groups based on the E/E'ratio as follows: GI, E/E'> 15 (n = 16; 9%); GII, E/E'8 to 15 (n = 79; 48%); and GIII, E/E'< 8 (n = 71; 43%). HFPEF was confirmed in GI and excluded in GIII. In GII, TDE [left atrial volume index (LAVI) ≥ 40 mL/m2; left ventricular mass index LVMI) > 122 for women and > 149 g/m2 for men] and ECG (atrial fibrillation) parameters were assessed, confirming HFPEF in 33 more patients, adding up to 49 (29%). In S2, patients were divided into three groups based on BNP levels. GI (BNP > 200 pg/mL) consisted of 12 patients, HFPEF being confirmed in all of them. GII (BNP ranging from 100 to 200 pg/mL) consisted of 20 patients with LAVI > 29 mL/m2, or LVMI ≥ 96 g/m2 for women or ≥ 116 g/m2 for men, or E/E'≥ 8 or atrial fibrillation on ECG, and the diagnosis of HFPEF was confirmed in 15. GIII (BNP < 100 pg/mL) consisted of 134 patients, 26 of whom had the diagnosis of HFPEF confirmed when GII parameters were used. Measuring BNP levels in S2 identified 4 more patients (8%) with HFPEF as compared with those identified in S1. Conclusion: The association of BNP measurement and TDE data is better than the isolated use of those parameters. BNP can be useful in identifying patients whose diagnosis of HF had been previously excluded based only on TDE findings.

Post-Hospital Syndrome: A New Challenge in Cardiovascular Practice

AbstractThe image of the hospital representing the modern medicine and its diagnostic and therapeutic advances becomes more evident in the face of an aging population and patients with multiple comorbidities requiring highly complex care. However, recent studies have shown a growing number of hospital readmissions within 30 days after discharge. The post-hospital syndrome is a new clinical entity associated with multiple vulnerabilities that contribute to hospital readmissions. During hospitalization, the patient is exposed to different stressors of physical, environmental, and psychosocial natures that trigger pathophysiological and multisystemic responses and increase the risk of complications after hospital discharge. Patients with a cardiac disease have high rates of readmission within 30 days. Therefore, it is important for cardiologists to recognize the post-hospital syndrome since it may impact their daily practice. This review aims at discussing the current scientific evidence regarding predictors and stressors involved in the post-hospital syndrome and the measures that are currently being taken to minimize their effects.

Derris (Lonchocarpus) urucu (Leguminosae) Extract Modifies the Peritrophic Matrix Structure of Aedes aegypti (Diptera:Culicidae)

Aqueous suspension of ethanol extracts of Derris (Lonchocarpus) urucu (Leguminosae), collected in the state of Amazonas, Brazil, were tested for larvicidal activity against the mosquito Aedes aegypti (Diptera:Culicidae). The aim of this study was to observe the alterations of peritrophic matrix in Ae. aegypti larvae treated with an aqueous suspension of D. urucu extract. Different concentrations of D. urucu root extract were tested against fourth instar larvae. One hundred percent mortality was observed at 150 µg/ml (LC50 17.6 µg/ml) 24 h following treatment. In response to D. urucu feeding, larvae excreted a large amount of amorphous feces, while control larvae did not produce feces during the assay period. Ultrastructural studies showed that larvae fed with 150 µg/ml of D. urucu extract for 4 h have an imperfect peritrophic matrix and extensive damage of the midgut epithelium. Data indicate a protective role for the peritrophic matrix. The structural modification of the peritrophic matrix is intrinsically associated with larval mortality.

First isolation of microorganisms from the gut diverticulum of Aedes aegypti (Diptera: Culicidae): new perspectives for an insect-bacteria association

We show for the first time that the ventral diverticulum of the mosquito gut (impermeable sugar storage organ) harbors microorganisms. The gut diverticulum from newly emerged and non-fed Aedes aegypti was dissected under aseptic conditions, homogenized and plated on BHI medium. Microbial isolates were identified by sequencing of 16S rDNA for bacteria and 28S rDNA for yeast. A direct DNA extraction from Ae. aegypti gut diverticulum was also performed. The bacterial isolates were: Bacillus sp., Bacillus subtilis and Serratia sp. The latter was the predominant bacteria found in our isolations. The yeast species identified was Pichia caribbica.

Effectiveness of glatiramer acetate compared to other multiple sclerosis therapies.

OBJECTIVE To assess the effectiveness of glatiramer acetate (GA) compared to other multiple sclerosis (MS) therapies in routine clinical practice. MATERIALS AND METHODS Observational cohort study carried out in MS patients treated with GA (GA cohort) or other MS therapies -switched from GA- (non-GA cohort). Study data were obtained through review of our MS patient database. The primary endpoint was the Expanded Disability Status Scale (EDSS) scores reached at the end of treatment/last check-up. RESULTS A total of 180 patients were included: GA cohort n = 120, non-GA cohort n = 60. Patients in the GA cohort showed better EDSS scores at the end of treatment/last check-up (mean ± SD, 2.8 ± 1.8 vs. 3.9 ± 2.2; P = 0.001) and were 1.65 times more likely to show better EDSS scores compared to the non-GA cohort (odds ratio, 0.606; 95%CI, 0.436-0.843; P = 0.003). Patients in the GA cohort showed longer mean time to reach EDSS scores of 6 (209.1 [95%CI, 187.6-230.6] vs. 164.3 [95% CI, 137.0-191.6] months; P = 0.004) and slower disability progression (hazard ratio, 0.415 [95%CI, 0.286-0.603]; P < 0.001). The annualized relapse rate was lower in the GA cohort (mean ± SD, 0.5 ± 0.5 vs. 0.8 ± 0.5; P = 0.001) and patients' quality of life was improved in this study cohort compared to the non-GA cohort (mean ± SD, 0.7 ± 0.1 vs. 0.6 ± 0.2; P = 0.01). CONCLUSIONS GA may slow down the progression of EDSS scores to a greater extent than other MS therapies, as well as achieving a greater reduction in relapses and a greater improvement in patients' quality of life. Switching from GA to other MS therapies has not proved to entail a better response to treatment.

A enfermeira diplomada e a luta contra tuberculose no Brasil: 1961-1966

O objeto desse estudo é a reconfiguração do Serviço de Enfermagem do Hospital Estadual Santa Maria, frente a uma nova política contra a tuberculose no Brasil. Objetivos: descrever as circunstâncias que ensejaram a implantação do novo Programa de Ação na Luta contra a Tuberculose no Brasil, e discutir as estratégias utilizadas pelas enfermeiras diplomadas do Hospital Estadual Santa Maria, no Estado da Guanabara, para adequar a assistência de enfermagem ao novo programa de combate à tuberculose. Estudo histórico-social. Para sua elaboração, foi realizada pesquisa documental, entrevistas e depoimentos de enfermeiras da época. A análise do corpus documental, apoiada pelos conceitos de habitus, campo e poder simbólico de Pierre Bourdieu, se fez com base em documentos escritos, orais e fontes secundárias. Resultados: a reconfiguração do serviço de enfermagem se deu sob a liderança de uma enfermeira cujo capital simbólico lhe conferia poder e prestígio para implementar as mudanças necessárias. Pode-se concluir que a atuação dessa enfermeira possibilitou a implantação do novo programa, e contribuiu para demarcar o espaço e a importância da enfermeira diplomada na assistência aos acometidos de tuberculose, tanto nos aspectos de prevenção quanto nos de cura.
