Arquivos Brasileiros de Cardiologia , 2004, DOI: 10.1590/S0066-782X2004001500003
Abstract: objective: to assess the echocardiographic findings in patients with suspected infective endocarditis. methods: two hundred sixty-two patients with suspected infective endocarditis underwent transthoracic and transesophageal echocardiographic investigation. images of vegetations, valvular abscesses, and acute periprosthetic insufficiency were analyzed, and the correlation with clinical and laboratory data, diagnostic category, and hospital evolution was assessed. results: the diagnosis of endocarditis was categorized as defined in 127 (47.8%) episodes, possible in 81 (30.4%), and rejected in 58 (21.8%). in patients with the defined diagnosis, the following images were identified: 135 vegetations, 37 abscesses, and 6 periprosthetic insufficiencies. vegetations were more frequent in patients with endocarditis due to streptococci of the viridans group and enterococci (p=0.02), and with symptom duration < 10 days (p=0.001). abscesses were more frequent in patients with symptom duration < 10 days (p=0.001). periprosthetic insufficiency was associated with a greater need for surgical treatment (p=0.001). in patients with the possible diagnosis of endocarditis, 8 echocardiographic images considered compatible with vegetations were identified. in patients whose diagnosis of endocarditis was rejected, no vegetations, valvular abscesses, or periprosthetic insufficiencies were demonstrated. conclusion: our echocardiographic findings varied according to the diagnostic category. the contribution to both the diagnosis and prognostic evaluation should consider the pretest probability of the diagnosis of infective endocarditis.

Abstract: the intensive cultivation of soil and the use of machines and equipment promote soil compaction. soil penetration resistance is a measure that detects this compaction, nevertheless soil moisture influences hardly on soil penetration resistance. the objective of this work was to evaluate the effect of soil moisture on the spatial variability of soil penetration resistance of an oxisol. an area cultivated for 40 years with sugarcane was sampled in the crossing points of a regular grid, with 10 m intervals, comprising 100 points. soil samples were collected at 0.00-0.15m, 0.15-0.30m and 0.30-0.45m depths, 24 and 72 hours after a 38mm precipitation. soil penetration resistance values indicated that compaction was high at the two sampling periods. soil moisture influenced the spatial variability of soil penetration resistance and a smaller spatial dependence was related to higher soil moistures. the grid used for the evaluation of soil penetration resistance variability must be closer than the one used for this study when the soil moisture is higher than the moisture observed 72 hours after the precipitation.

Abstract: objectives: to identify initial predictive factors of renal involvement in children and adolescents with henoch-sch?nlein purpura. methods: we reviewed the medical records of 142 patients admitted to our university hospital over a 21-year period with a diagnosis of henoch-sch?nlein purpura. the initial predictive factors assessed, observed during the first 3 months, included: demographic data, clinical manifestations (persistent palpable purpura, arthritis, abdominal pain, severe abdominal pain, gastrointestinal bleeding, orchitis, central nervous system involvement and pulmonary hemorrhage), laboratory tests (serum iga levels) and treatment given (corticosteroids, intravenous immunoglobulin and immunosuppressive drugs). patients were divided into two groups (presence or absence of nephritis) and assessed by univariate and multivariate analysis. results: evidence of nephritis was detected in 70 patients (49.3%). the univariate analysis revealed that severe abdominal pain (p = 0.0049; or = 1.6; 95%ci 1.18-2.21), gastrointestinal bleeding (p = 0.004; or = 1.6; 95%ci 1.10-2.26) and corticosteroid use (p = 0.0012; or = 1.7; 95%ci 1.28-2.40) were all associated with increased incidence of renal involvement. in the multivariate analysis, logistic regression demonstrated that the only independent variable that predicted nephritis was intense abdominal pain (p < 0.012; or = 2.593; 95%ci 1.234-5.452). conclusions: severe abdominal pain was a significant predictor of nephritis in henoch-sch?nlein purpura. consequently, pediatric patients exhibiting this clinical manifestation should be rigorously monitored, due to the increased risk of renal involvement.

Abstract: We have generated 13,249 expressed sequence tags (ESTs) from developing and germinating Jatropha seeds. This strategy allowed us to detect most known genes related to lipid synthesis and degradation. We have also identified ESTs coding for proteins that may be involved in the toxicity of Jatropha seeds. Another unexpected finding is the high number of ESTs containing transposable element-related sequences in the developing seed library (800) when contrasted with those found in the germinating seed library (80).The sequences generated in this work represent a considerable increase in the number of sequences deposited in public databases. These results can be used to produce genetically improved varieties of Jatropha with increased oil yields, different oil compositions and better agronomic characteristics.The need to reduce greenhouse gas emissions and provide fuel security has increased the demand for oil-rich plants as raw materials for biodiesel production. Although vegetable oils have long been used for food, the ideal crop source for biodiesel products should consider other ecological, environmental and ethical concerns. Ideally, the entire process, from cultivation to fuel burning in engines, should favour carbon sequestration, reduce water needs and promote energy efficiency. Moreover, the impact of oil crops for biodiesel production on the prices of food commodities is a matter of concern. Ideally, such crops should be non-edible and grown on non-agricultural lands so that they do not compete for soil with food crops and do not affect the price of food commodities.Jatropha curcas L. (family Euphorbiaceae) is a perennial, drought-resistant and non-food oilseed crop that has high oil content and fulfils many of the requirements for biodiesel production. Jatropha is currently one the most promoted oilseed crops and its seeds have an oil content of up to 50% [1]. Its major fatty acids are oleic acid (34.3-45.8%; 18:1), linoleic acid (29.0-44.2%; 18:2), palmitic a

Abstract: background: despite major advances in interventional cardiology in recent years, no-reflow is still observed during percutaneous coronary interventions (pci), and is associated to a worse prognosis. the objective of this study was to characterize the clinical, angiographic and procedural profile of patients with no-reflow as well as assessing its late clinical impact. methods: from january 2004 to february 2009, patients undergoing pci at the instituto do cora??o (incor), presenting no-reflow at any time during the intervention, were evaluated. patients were divided into two groups: reperfusion no-reflow (associated to primary pci) and interventional no-reflow (associated to elective pci). the probability of death was estimated by the kaplan-meier method and cox regression was used to identify its predictors. results: one hundred and thirty-two consecutive patients were evaluated, 81 in the reperfusion no-reflow group and 51 in the interventional no-reflow group. procedural success was observed in 83.5% of the overall population (80.2% vs. 90.2%, respectively; p = 0.149). the long-term probability of death was estimated at 38.6%, and was higher in the reperfusion no-reflow group (55.8% vs. 11.1%; p = 0.005). in the multivariate analysis, only female gender [hazard ratio (hr) 2.5, 95% confidence interval (95% ci) 1.225.14; p = 0.027) and chronic obstructive pulmonary disease (hr 9.35, ci 95% 1.45-60.14; p = 0.027) were independent predictors of mortality, whereas the prior use of statin was a protective factor (hr 0.15, 95% ci 0.05-0.48; p = 0.002). conclusions: the no-reflow phenomenon was associated with high procedural failure rates and long-term mortality, especially when associated to primary angioplasty.

Abstract: background: percutaneous coronary intervention (pci) in unprotected left main coronary artery (lmca) disease has proven to be an alternative to coronary artery bypass graft surgery (cabg). however, late clinical results of pci in these patients are scarce in the literature, especially in our country. method: data from a tertiary cardiology center registry, which included patients with contraindications to cabg undergoing lmca pci, from 2002 to 2009, were analyzed. our objective was to evaluate the 1-year mortality. results: a total of 77 subjects were included in this analysis, mean age was 65.4 ± 13.7 years, 59.2% were male, 25% were diabetic, and 3.9% had renal failure requiring dialysis. regarding the angiographic characteristics, 79.6% of lesions were type b2/c, with involvement of the ostium in 47.4% and distal bifurcation in 62.3%. in most cases pci was performed as an emergency procedure (85.5%) and drug eluting stents were used in 17.5% of the patients. hemodynamic support using an intraaortic balloon pump was used in 28.2% of the population. at the end of 1 year the probability of overall survival was 69.7% and almost all of the deaths occurred in the first month of follow-up. conclusion: in this highly selected population with unprotected lmca disease, including high-surgical-risk patients, in clinical emergency situations and with complex lesions, pci is feasible and has acceptable 1-year mortality rates.

Abstract: the objective of this work was to evaluate the performance of heifers fed sugarcane silages produced with and without additives. thirty-two holstein heifers were randomly assigned, in a block design, to evaluate rations (46% silage; 54% concentrate; 12% crude protein) containing silages treated with (fresh basis) urea (0.5%), sodium benzoate (0.1%) or lactobacillus buchneri (3.64x105 cfu g-1 ). inoculation with l. buchneri improved daily gain (1.24 vs. 0.94 kg day-1 ), and the addition of benzoate resulted in better feed conversion (7.6 vs. 9.4 kg of dry matter per kg of live weight), in relation to the untreated silage (control). treatments did not affect dry matter intake (mean of 2.19% of live weight). rations containing silages treated with benzoate or l. buchneri showed lower cost per kg of weight gain. treatment with urea did not improve animal performance, but the cost per kg of weight gain was lower than that of the control ration.

Abstract: unipolar pulse generators, either single or dual chamber, can be inhibited or reverted to the asynchronous mode, by skeletal muscle myopotentials. dual chamber pacemakers may even stimulate the ventricle at the upper rate limit because of myopotential sensing via the atrial channel. a unipolar anti-tachycardia generator may be triggered by myopotentials to provoke an arrhythmia. during bipolar implanted pacing, episodic ventricular tachycardia has been induced in three patients with chagasic cardiomyopathy and anodal stimulation has been shown to be the cause. both unipolar and bipolar stimulation modes present problems. a stimulation mode with the cathode intracardiac and the anode remote from the generator and the patient's heart, called "tele-anode" was developed to be implanted in the presternal area or in venous system and avoid pacemaker triggering and inhibition. the subcutaneous "tele-anode" may be a spiral or a cylinder while an intravascular "tele-anode" may be positioned in the superior or inferior vena cava. until march, 1986, 62 patients underwent "tele-anode" implantation, 57 at the sternum (51 spiral and 6 cylindrical) and 5 intramuscular. thirty five generators were single chamber ventricular inhibited, 23 were dual chamber, 3 were atrial inhibited and 1 ventricular anti-tachycardia. in all cases the stimulation thresholds and electrogram characteristics were similar between intracardiac cathode and "tele-anode" and cathode and the puise generator site. only electromyographic signals were consistently attenuated. one patient with an intravascular "tele-anode" died postoperatively of ventricular arrhythmias and one required ventricular lead repositioning. the 61 living patients, followed from one to twenty-one months, have shown no inhibition, triggering or noise mode reversion at nominal sensitivity setting. the authors conclude that pacemakers implanted with "tele-anode" show a clear evidence of decrease of associated complications, inherent to the

Abstract: the purpose of this paper was to evaluate the association between ideal number of children (inc) and female sterilization. a nested case-control study was performed through a secondary analysis of data from a cohort study on the reproductive health of women in campinas, s?o paulo, brazil. a total of 3,878 women were included, 1,012 being sterilized (cases). the relationship between inc and number of live births (lb) was divided in two categories (inc > lb and inc ? lb). the relative risks of performing tubal ligation were calculated (odds ratio) with their respective 95% confidence intervals for the relation inc/lb and all control variables. all predictor variables were included in a logistic regression model in order to identify the factors independently associated with female sterilization. the results showed that the risks of tubal ligation were higher among women with inc < lb, higher age, with partners, higher family income, more than two previous pregnancies, more deliveries, fewer abortions, and without paid work.
