OBJETIVOS: identificar os determinantes associados ao perfil da automedicação na população de idosos de 60 anos e mais, no município de Salgueiro/Pernambuco/Brasil. MÉTODO: Estudo de corte transversal realizado na zona urbana no município de Salgueiro - PE. Entre 01/05 a 10/06/2004, foram aplicados questionários em uma amostra de 355 indivíduos da população de 60 anos e mais. Os dados foram processados e analisados no EPIINFO 6.04 após digitação em dupla entrada e validação. RESULTADOS: 44,9% dos entrevistados encontravam-se na faixa etária de 60-70 anos, 247 (69,8%) eram do sexo feminino, 188 (53,1%) eram analfabetos e 145 (40,7%) tinham o primeiro grau incompleto, sendo 276 (77,7%) aposentados. Entre os que faziam uso de medicamentos sem receita médica houve predomínio de analgésicos (30%) e antipiréticos (29%). Entre os motivos mais freqüentes apresentados, e que levavam os indivíduos a tomar remédios por conta própria, a dor tem o maior índice (38,3%), seguida de febre (24,4%), diarréia (8,0%), pressão alta (8,0%) e tosse (5,2%). Houve associação entre a ausência de atividade física e automedicação (x² =14,44, p=0,001). CONCLUSÃO: existe grande prevalência da automedicação neste grupo, sendo os analgésicos e os antipiréticos os mais utilizados; a dor é o sintoma que mais leva à automedicação; os idosos sedentários se automedicam mais que os praticantes de atividade física.

Perioperative inflammation is proposed to be involved in the pathogenesis of POAF. Therefore, perioperative assessment of CRP, IL-6, IL-8, and IL-10 can help clinicians in terms of predicting and monitoring for POAF.

BackgroundAtrial fibrillation (AF) is one of the most critical and frequent arrhythmias precipitating morbidities and mortalities. The complete blood count (CBC) test is an important blood test in clinical practice and is routinely used in the workup of cardiovascular diseases. This systematic review with meta-analysis aimed to determine the strength of evidence for evaluating the association of hematological parameters in the CBC test with new-onset and recurrent AF.Material/MethodsWe conducted a meta-analysis of observational studies evaluating hematologic parameters in patients with new-onset AF and recurrent AF. A comprehensive subgroup analysis was performed to explore potential sources of heterogeneity.ResultsThe literature search of all major databases retrieved 2150 studies. After screening, 70 studies were analyzed in the meta-analysis on new-onset AF and 23 studies on recurrent AF. Pooled analysis on new-onset AF showed platelet count (PC) (weighted mean difference (WMD)=WMD of −26.39×109/L and p<0.001), mean platelet volume (MPV) (WMD=0.42 FL and p<0.001), white blood cell (WBC) (WMD=−0.005×109/L and p=0.83), neutrophil to lymphocyte ratio (NLR) (WMD=0.89 and p<0.001), and red blood cell distribution width (RDW) (WMD=0.61% and p<0.001) as associated factors. Pooled analysis on recurrent AF revealed PC (WMD=−2.71×109/L and p=0.59), WBC (WMD=0.20×109/L (95% CI: 0.08 to 0.32; p=0.002), NLR (WMD=0.37 and p<0.001), and RDW (WMD=0.28% and p<0.001).ConclusionsHematological parameters have significant ability to predict occurrence and recurrence of AF. Therefore, emphasizing the potential predictive role of hematological parameters for new-onset and recurrent AF, we recommend adding the CBC test to the diagnostic modalities of AF in clinical practice.

Fatores de risco para síndrome de baixo débito cardíaco após cirurgia de revascularização miocárdicaRisk factors for low cardiac output syndrome after coronary artery bypass grafting surgery Abstract Objectives: Low cardiac output syndrome (LCOS) is a serious complication after cardiac surgery and is associated with significant morbidity and mortality. The aim of this study is to identify risk factors for LCOS in patients undergoing coronary artery bypass grafting (CABG) in the Division of Cardiovascular Surgery of Pronto Socorro Cardiológico de Pernambuco -PROCAPE (Recife, PE, Brazil).Methods: A historical prospective study comprising 605 consecutive patients operated between May 2007 and December 2010. We evaluated 12 preoperative and 7 intraoperative variables. We applied univariate and multivariate logistic regression analysis.Results: The incidence of LCOS was 14.7% (n = 89), with a lethality rate of 52.8% (n = 47). In multivariate analysis by logistic regression, four variables remained as independent risk factors: age ≥ 60 years (OR 2.00, 95% CI 1.20 to 6.14, P = 0.009), on-pump CABG (OR 2.16, 95% CI 1.40 to 7.08, P = 0.006), emergency surgery (OR 4.71, 95% CI 1.34 to 26.55, P = 0.028), incomplete revascularization (OR 2.62, 95% CI 1.32 to 5.86, P = 0.003), and ejection fraction <50%.Conclusions: This study identified the following independent risk factors for LCOS after CABG: age ≥ 60 years of off-pump CABG, emergency surgery, incomplete CABG and ejection fraction <50%.

Haematological indices may predict the risk of POAF before surgery. These easily-performed tests should defi¬nitely be taken into account in patients undergoing isolated CABG, valvular surgery, or combined procedures.

ObjectiveTo determine whether stratification of complexity models in congenital heart surgery (RACHS-1, Aristotle basic score and STS-EACTS mortality score) fit to our center and determine the best method of discriminating hospital mortality.MethodsSurgical procedures in congenital heart diseases in patients under 18 years of age were allocated to the categories proposed by the stratification of complexity methods currently available. The outcome hospital mortality was calculated for each category from the three models. Statistical analysis was performed to verify whether the categories presented different mortalities. The discriminatory ability of the models was determined by calculating the area under the ROC curve and a comparison between the curves of the three models was performed.Results360 patients were allocated according to the three methods. There was a statistically significant difference between the mortality categories: RACHS-1 (1) - 1.3%, (2) - 11.4%, (3)-27.3%, (4) - 50 %, (P<0.001); Aristotle basic score (1) - 1.1%, (2) - 12.2%, (3) - 34%, (4) - 64.7%, (P<0.001); and STS-EACTS mortality score (1) - 5.5 %, (2) - 13.6%, (3) - 18.7%, (4) - 35.8%, (P<0.001). The three models had similar accuracy by calculating the area under the ROC curve: RACHS-1- 0.738; STS-EACTS-0.739; Aristotle- 0.766.ConclusionThe three models of stratification of complexity currently available in the literature are useful with different mortalities between the proposed categories with similar discriminatory capacity for hospital mortality.
