8Chagas heart disease:An overview of diagnosis,manifestations,treatment,and care显示文摘Chagas heart disease(CHD)affects approximately 30%of patients chronically infected with the protozoa Trypanosoma cruzi.CHD is classified into four stages of increasing severity according to electrocardiographic,echocardiographic,and clinical criteria.CHD presents with a myriad of clinical manifestations,but its main complications are sudden cardiac death,heart failure,and stroke.Importantly,CHD has a higher incidence of sudden cardiac death and stroke than most other cardiopathies,and patients with CHD complicated by heart failure have a higher mortality than patients with heart failure caused by other etiologies.Among patients with CHD,approximately 90%of deaths can be attributed to complications of Chagas disease.Sudden cardiac death is the most common cause of death(55%–60%),followed by heart failure(25%–30%)and stroke(10%–15%).The high morbimortality and the unique characteristics of CHD demand an individualized approach according to the stage of the disease and associated complications the patient presents with.Therefore,the management of CHD is challenging,and in this review,we present the most updated available data to help clinicians and cardiologists in the care of these patients.We describe the clinical manifestations,diagnosis and classification criteria,risk stratification,and approach to the different clinical aspects of CHD using diagnostic tools and pharmacological and non-pharmacological treatments.Roberto M Saraiva Mauro Felippe F Mediano Fernanda SNS Mendes Gilberto Marcelo Sperandio da Silva Henrique H Veloso Luiz Henrique C Sangenis Paula Simplício da Silva Flavia Mazzoli-Rocha Andréa S Sousa Marcelo T Holanda Alejandro M Hasslocher-Moreno 2021World Journal of Cardiology2021,13,12:1
9Improving wood volume predictions in dry tropical forest in the semi-arid Brazil显示文摘The volumetric variability of dry tropical forests in Brazil and the scarcity of studies on the subject show the need for the development of techniques that make it possible to obtain adequate and accurate wood volume estimates.In this study,we analyzed a database of thinning trees from a forest management plan in the Contendas de SincoráNational Forest,southwestern Bahia State,Brazil.The data set included a total of 300 trees with a trunk diameter ranging from 5 to 52 cm.Adjustments,validation and statistical selection of four volumetric models were performed.Due to the difference in height values for the same diameter and the low correlation between both variables,we do not suggest models which only use the diameter at breast height(DBH)variable as a predictor because they accommodate the largest estimation errors.In comparing the best single entry model(Hohenald-Krenn)with the Spurr model(best fit model),it is noted that the exclusion of height as a predictor causes the values of 136.44 and 0.93 for Akaike information criterion(AIC)and adjusted determination coefficient(R2 adj),which are poorer than the second best model(Schumacher-Hall).Regarding the minimum sample size,errors in estimation(root mean square error(RMSE)and bias)of the best model decrease as the sample size increases,especially when a larger number of trees with DBH≥15.0 cm are randomly sampled.Stratified sampling by diameter class produces smaller volume prediction errors than random sampling,especially when considering all trees.In summary,the Spurr and Schumacher-Hall models perform better.These models suggest that the total variance explained in the estimates is not less than 95%,producing reliable forecasts of the total volume with shell.Our estimates indicate that the bias around the average is not greater than 7%.Our results support the decision to use regression methods to build models and estimate their parameters,seeking stratification strategies in diameter classes for the sample trees.Volume estimates with valid confidence intervals can be obtained using the Spurr model for the studied dry forest.Stratified sampling of the data set for model adjustment and selection is necessary,since we find significant results with mean error square root values and bias of up to 70%of the total database.Robson B de LIMA Patrícia A B BARRETO-GARCIA Alessandro de PAULA Jhuly E S PEREIRA Flávia F de CARVALHO Silvio H M GOMES 2020Journal of Arid Land2020,12,6:0
