Objective:To evaluate the role of N-terminal pro-brain-type natriuretic peptide (NT-proBNP) and a cardiovascular (CV) risk score named FRESCO for predicting anthracycline-induced cardiotoxicity (AIC) in diffuse large B-cell lymphoma (DLBCL). Methods:A total of 130 consecutive DLBCL patients treated in first-line with anthracycline-containing immunochemotherapy. Competitive risk between NT-proBNP, FRESCO, and time to AIC was considered.Results: Cumulative incidence of AIC was 12.2% and 17.5% at 1 and 5 years, respectively. Median time to development cardiotoxicity was 6.4 months, with half of the cases showing heart failure and the other half silent AIC. Both NT-proBNP levels and FRESCO score were independently associated with higher risk of AIC (P = 0.001 and P = 0.03, respectively). Patients with NT-proBNP ≥600 pg/mL or those with FRESCO ≥4.5% had 3.97 or 2.54 times higher risk of AIC than those with lower values (P = 0.001 and P = 0.048, respectively). According to the previous cutoffs, three groups of patients with a significantly different risk of AIC could be identified (P < 0.0001).Conclusions: Doxorubicin-containing chemotherapy is associated with increased risk of silent and overt AIC. Baseline NT-proBNP levels and FRESCO CV risk score are accurate predictors of AIC and can identify groups of patients at different risk, in which personalized cardiologic evaluation should be offered.

<div><b><i>Objective</i></b> To explore the meal response of circulating succinate in patients with obesity and type 2 diabetes undergoing bariatric surgery, and to examine the role of gastrointestinal glucose sensing in succinate dynamics in healthy subjects. <b><i><br></i></b></div><div><b><i>Research Design and</i></b> <b><i>Methods</i></b> Cohort I comprised 45 patients with morbid obesity and type 2 diabetes (BMI 39.4±1.9 kg/m²) undergoing metabolic surgery. Cohort II was a confirmatory cohort of 13 patients (BMI 39.3±1.4 kg/m²) undergoing gastric bypass surgery. Cohort III comprised 15 healthy subjects (BMI 26.4±0.5 kg/m²). Cohorts I and II completed a 2-hour meal tolerance test (MTT) before the intervention and at one-year of follow-up, and cohort II also completed a 3-hour lipid test (LT). Cohort III underwent a 3-hour oral glucose tolerance test (OGTT) and an isoglycemic variable glucose infusion (ISO) study. </div> <p><b><i>Results</i></b><i> </i>In cohort I, succinate response to MTT at follow-up was greater than before the intervention (p<0.0001). This response was confirmed in cohort II with a greater increase after one year of surgery (p=0.009). By contrast, LT did not elicit a succinate response. Changes in succinate response were associated with changes in the area under the curve of glucose (r=0.417, p<0.0001) and insulin (r=0.204, p=0.002). In cohort III, glycemia <i>per se</i> stimulated a plasma succinate response (p=0.0004), but its response was greater in the OGTT (p=0.02; OGTT <i>versus</i> ISO). </p> <p><b><i>Conclusions</i></b><b> </b>The<b> </b>meal-related response of circulating succinate in patients with obesity and type 2 diabetes is recovered after metabolic surgery.</p>

IntroductionA considerable proportion of patients with morbid obesity require treatment with antidepressants.ObjectivesThe aim of this study is to determine the incidence of patients who are in antidepressant treatment and identify risk factors for the need of this treatment in patients with morbid obesity.Materials and methodsRetrospective cohort study of 292 patients with morbid obesity who underwent bariatric surgery at Hospital del Mar from January 2010 to November 2015. The incidence of antidepressant treatment was analyzed, and also its possible relationship with the following variables: age, sex, BMI, tobacco smoking, alcohol consumption and age of onset of obesity. Chi2 test for categorical variables and Student t-test for quantitative variables were applied. Afterwards, a multivariate analysis was performed using logistic regression.ResultsThe mean age is 43.1 years. Most of the patients (76.4%) are women. Seventy-seven patients (26.4%) are receiving treatment with antidepressants. There is a statistically significant relationship between age and the need of treatment with antidepressants (P < 0.001). This relationship is still present when the variables are analyzed using logistic regression (P < 0.005, OR 1.049). We have not found any significant relationship with the rest of the variables.ConclusionsDespite the large number of patients in the study, there are limitations, such as being a retrospective study and not being adjusted for confounding factors. From all the variables that have been analyzed we have found that as the age of the patients increase, there is a higher number of patients that receive treatment with antidepressants.Disclosure of interestThe authors have not supplied their declaration of competing interest.
