RESUMEN

OBJECTIVES: We sought to determine the relationship between in-hospital mortality and the neutrophil-to-lymphocyte ratio (NLR) in patients with ST-elevation myocardial infarction (STEMI) undergoing with pharmaco-invasive strategy (PIS). BACKGROUND: Increased levels of white blood cells have been associated with adverse clinical outcomes in patients with (STEMI). NLR has recently emerged as a potent and more specific prognostic marker in predicting short- and long-term mortalityin patients undergoing primary percutaneous coronary intervention. This association has never been reported in patients managed with PIS. METHODS: Between March 2010 and October 2016, 1860 STEMI patients managed with PIS were consecutively included in a dedicated database. The study population was divided into tertiles based on the admission NLR values (lower: <4.0, intermediate: 4.0 to <7.3, and upper: ≥7.3). Co-primary endpoints were in-hospital mortality and MACE (death, non-fatal reinfarction or stent thrombosis). RESULTS: Patients in the upper NLR tertile had significantly higher in-hospital mortality (9.0% vs. 4.8% versus. 1.8%, p < 0.001) and MACE (11.6% vs. 8.0% versus 2.9%, p < 0.001) than patients with intermediate or low NLR. By multivariable logistic regression analysis, the upper NLR tertile was an independent predictor of MACE (odds radio [OR] 4.19, 95% confidence interval [95% CI] 2.23-7.88, p < 0.001) and in-hospital mortality [OR 3.32, 95% CI 1.19-9.28, p = 0.02]. CONCLUSION: High NLR values were independently associated with in-hospital MACE and death in STEMI patients submitted to a PIS. NLR might be a simple and useful risk stratification tool in this high-risk population.

RESUMEN

The aim was to evaluate the use of white sugar as carbon source for shrimp nursery reared in in a biofloc system. We used Eight tanks of 800 L stoked with 3000 shrimp m-3. Half of the tanks received white sugar as a carbon source and other tanks molasses (control). Water quality parameters remained within the recommended limits for marine shrimp. However, the total ammonia was higher in the treatment with white sugar compared to control. The alkalinity and phosphate were higher in control. The performance (final weight, survival, feed conversion and productivity) were not different between treatments. Nevertheless, the cost of white sugar in kilogram of shrimp produced was 62% lower compared to treatment with molasses. The study showed that white sugar can be used in shrimp nursery fertilization and aids to reduce production costs.

Objetivou-se avaliar o uso de açúcar refinado como fonte de carbono no berçário de camarões marinhos em sistema de bioflocos. Foram utilizados oito tanques de 800 L povoados com 3.000 camarões m-3, sendo que metade dos tanques recebeu açúcar refinado como fonte de carbono e o restante, melaço de cana-de-açúcar (controle). Os valores dos parâmetros de qualidade de água mantiveram-se dentro dos limites aceitáveis para o camarão marinho. Contudo, o teor de amônia total foi superior no tratamento com açúcar refinado em relação ao registrado no controle. A alcalinidade e fosfato foram superiores no controle. Os índices produtivos avaliados (peso final, sobrevivência, conversão alimentar e produtividade) não foram diferentes entre os tratamentos. Entretanto, o custo do açúcar refinado para produção de um quilograma do camarão foi 62% inferior ao do melaço (tratamento controle). O estudo mostra que o açúcar refinado pode ser usado na fertilização do berçário de camarão e auxiliar na redução dos custos de produção.

RESUMEN

A via radial é amplamente utilizada para a realização de cateterismo cardíaco e angioplastia, com vantagens como a diminuição do risco de sangramento e de complicações vasculares. O presente caso relata uma complicação rara durante o cateterismo cardíaco por via radial: a avulsão de tecido endotelial da artéria radial pelo cateter e sua embolização para a artéria descendente anterior, a qual foi resolvida pela aspiração manual do fragmento embolizado. Tal complicação pode ter relação com as características anatômicas específicas da artéria radial do paciente

The radial access is widely used for cardiac catheterization and angioplasty, with advantages such as decreased risk of bleeding and vascular complications. This case reports on a rare complication during cardiac catheterization by radial access: radial artery endothelial tissue avulsion through the catheter and its embolization to the left anterior descending artery, which was resolved by manual aspiration of the embolized fragment. This complication may be related to the specific anatomical characteristics of the patient's radial artery

RESUMEN

Apesar de a alta hospitalar no mesmo dia (AHMD) após intervenção coronária percutânea(ICP) eletiva não complicada ser adotada mundialmente, ela permanece pouco estudada em nosso meio.Objetivamos, assim, avaliar nossa experiência inicial com a AHMD após ICP eletiva, em relação à suas egurança e aos preditores de sucesso. Métodos: Foram incluídos 161 pacientes consecutivos para AHMD, de único centro, selecionados em ambulatório especializado. Para a identificação dos fatores associados ao sucesso da AHMD, foram ajustados modelos de regressão logística simples e múltipla. Resultados: A AHMD foi realizada com sucesso em 114 pacientes (70,8%), tendo os 47 pacientes restantes permanecido internados (45 com alta na manhã seguinte e 2 pacientes após 2 dias). Nenhum paciente com AHMD apresentou evento cardíaco adverso maior ou complicação vascular importante aos 30 dias e no seguimento mediano de 12 meses. No grupo internação, ocorreu apenas um caso de infarto agudo do miocárdio por oclusão de ramo lateral e dois hematomas > 5 cm relacionados ao sítio de punção. Os preditores de sucesso da AHMD foram: via de acesso radial (OR = 5,92; IC95% 1,73-20,21; p = 0,005), presença de lesões tipo A/B1 (OR = 14,09; IC95% 1,70-116,49; p = 0,01) e volume de contraste (OR = 0,76;IC95% 0,65-0,88; p < 0,001). Conclusões: A AHMD foi segura e pôde ser realizada com sucesso na maioria dos pacientes selecionados para ICP eletiva, sendo seus preditores de sucesso o acesso radial, as lesões menos complexas e um volume menor de contraste...

Background: Although same-day discharge (SDD) after elective uncomplicated percutaneous coronary intervention (PCI) be adopted worldwide, it remains poorly studied in our country. We aim to evaluate our initial experience with SDD after elective PCI, regarding its safety and predictors of success. Methods: A hundred and sixty-one single-center consecutive patients, selected in a specialized out patient clinic, were included for SDD. To identify the factors associated with SDD, single and multiple logistic regression models were adjusted. Results: SDD was successfully performed in 114 patients (70.8%) and the remaining 47 patients remained hospitalized (45 with discharge in the following morning and 2 patients after 2 days). No patient with SDD presented major adverse cardiac events or major vascular complications at 30 days or at a median follow-up of 12 months. In the inpatient group, there was only one case of acute myocardial infarction due to a lateral branch occlusion and two patients with > 5 cm hematoma related to the access site. The SDD predictors were radial access route (OR = 5.92; 95%CI 1.73-20.21; p = 0.005), presence of type A/B1 lesions(OR = 14.09; 95%CI 1.70-116.49%; p = 0.01) and contrast volume (OR = 0.76; 95%CI 0.65-0.88; p < 0.001). Conclusions: SDD was safe and could be successfully performed in most patients selected for elective PCI, and its predictors were the radial access, less complex coronary lesions and a and lower contrast volume...

RESUMEN

The patient, MSM, a 69-year-old man, sought medical care due to left dorsal and right lower limb pain. The chest x-ray showed mediastinal enlargement. He was undergoing examination when he lost consciousness and went into shock. Subcutaneous emphysema was observed in the left hemithorax, as well as abolition of breath sounds at auscultation. Tracheal intubation was performed with draining of blood-tinged fluid from the left hemithorax. Echocardiography showed left ventricle with 44/29 mm; septum, 12 mm; posterior wall, 13 mm; mild aortic root dilation, dissection of the lamina and periaortic hematoma. The valves and pericardium were normal. The patient was transferred to Instituto do Coraçao - InCor. Physical examination (21 Oct 2004: 10:45) showed that the patient was sedated with tracheal intubation, pale, heart rate at 90 bpm, blood pressure 130 x 80 mmHg, bloody drainage in the chest tube. Electrocardiogram - frequency 90 bpm, sinus rhythm, low voltage in the frontal plane and decreased voltage in left leads (Fig. 1). Computed tomography showed bilateral subcutaneous emphysema, thoracic aorta with inaccurate borders in its descending portion (from the subclavian artery to the middle portion), collapsed left lung and extensive collection of hematic characteristics in same hemithorax and middle and posterior mediastinum. Small right pneumothorax; small right pleural effusion with underlying parenchymal alterations. The analysis of the heart was impaired by the presence of hemothorax. While undergoing computed tomography, the patient showed no pulse, mydriasis, with asystole unresponsive to resuscitation and died (21 Oct 2011; 15:00 h).

RESUMEN

MSM, homem, 69 anos, procurou atendimento médico por dor em dorso esquerdo e membro inferior direito. A radiografia de tórax revelou alargamento do mediastino. Estava em observação quando apresentou rebaixamento da consciência e choque. Foi observado enfisema subcutâneo em hemitórax esquerdo e abolição do murmúrio vesicular em base do mesmo pulmão. Foi feita a intubação orotraqueal e realizada drenagem de hemitórax esquerdo, com saída de líquido serossanguinolento. O ecocardiograma revelou ventrículo esquerdo (D/S): 44/29 mm; septo 12 mm; parede posterior 13 mm; discreta dilatação em raiz da aorta, presença de lâmina de dissecção e hematoma periaórtico. As valvas e pericárdio eram normais. O paciente foi transferido para o InCor. O exame físico (21 out 2004: 10h45) revelou paciente sedado, com intubação orotraqueal, com palidez cutânea, frequência cardíaca 90 bpm, pressão arterial 130 x 80 mmHg, drenagem torácica sanguinolenta do dreno tórax. Eletrocardiograma - frequência 90 bpm, ritmo sinusal, baixa voltagem no plano frontal e diminuição de voltagem em derivações esquerdas (fig. 1). A tomografia revelou enfisema subcutâneo bilateral, aorta torácica com contornos imprecisos na sua porção descendente (da artéria subclávia até porção média), colapso do pulmão esquerdo e grande coleção de características hemáticas em mesmo hemitórax e no mediastino médio e posterior. Pequeno pneumotórax à direita; pequeno derrame pleural à direita com alterações do parênquima subjacente. A análise do coração foi prejudicada pela presença do hemotórax. Durante a realização de tomografia apresentou ausência de pulsos, midríase, com assistolia, sem resposta às manobras de ressuscitação e faleceu (21 out 2011; 15h).
