Fig. 4 in Systematics of the enigmatic South American Streblopus Van Lansberge, 1874 dung beetles and their transatlantic origin: a case study on the role of dispersal events in the biogeographical history of the Scarabaeinae (Coleoptera: Scarabaeidae)
Fig. 4. Distribution of Streblopus van Lansberge, 1874. Note how the two species are widely separated by the vast South American Dry Diagonal stretching between Amazonia and the Atlantic Forest. During several different times over the Neogene, forest corridors connected the two biomes and the populations of Streblopus could move from one to the other. When the forest retreated, the distribution of the genus became relict.

Data from: Adverse events related to intravenous antibiotic therapy: a prospective observational study in the treatment of infective endocarditis
Objective: The goal of this prospective observational present study was to identify adverse events (AEs) related to the use of intravenous access sites for infective endocarditis (IE) treatment in a tertiary care hospital that can occur during patient care that cannot be attributed to the underlying disease and may result in lengthening of hospital stay or death. Design: This is an observational, analytical and prospective study on AEs resulting from the use of intravenous access sites in patients under antimicrobial treatment for IE. Patients enrolled in the International Collaboration on Endocarditis (ICE) study had their peripheral, short term central catheters (CVC) and peripherally inserted central catheters (PICC) monitored for AEs. Setting: Tertiary care hospital for cardiac surgery in Rio de Janeiro, Brazil. Patients: Patients over 18 years of age, hospitalized in 2009 and 2010 with definite criteria for IE by the modified Duke criteria were included. Main outcome measures: Adverse events related to intravenous catheters: erythema and infiltration, fever, obstruction, externalization and blood stream infection. Results: Thirty-seven episodes of IE in 35 patients were studied. Mean age was 44.32 ± 15.2 years; 22 (63%) were male. 253 vascular catheters were studied, 148 peripheral, 85 CVC (21 of which for haemodialysis) and 20 PICC. The most frequent AEs were "erythema" and "infiltration" for peripheral catheters, "fever" for CVCs, and "obstruction" and "externalization" for PICCs. The number of catheter-days was 360 for peripheral catheters, 1.156 for CVC and 420 for PICC. Kaplan Meier curves for CVC and PICC showed statistical difference for obstruction (p<0.001) in PICCs. More bacteraemia occurred in CVC compared to PICC. Conclusion: The choice of intravenous access sites is critical in the treatment of IE. Close observation for adverse events and stricter implementation of infection control measures and better manipulation of catheters are suggested.
Fecal calprotectin as a predictor of gastrointestinal immune-related adverse events (CF-19): A prospective study - Excel data and supplementary tables
<p class="cuerpo"><b>Background: </b>Colitis is a frequent immune-related toxicity, without any biomarker that may predict its onset. It is endoscopically similar to intestinal inflammatory diseases, where fecal calprotectin (FC) is used as a biomarker to early-detect a relapse. We found contradictory evidence about FC and immunotherapy and no prospective study was already published. </p> <p class="cuerpo"><b>Methods:</b> We present an analytical, observational and prospective study of one year's duration. We analyzed FCbasal, and then prior to each cycle until the sixth, ending with quarterly follow-up. For evaluating the predictive value of FC we estimated the area under the ROC curve for basal absolute values and for each cycle, and calculated its relative percentage change with respect to basal. We also planned to estimate sensitivity, specificity and predictive values indexes for different cut-off points. Because of lack of recruitment we did a preliminary analysis at the end of the initially estimated period before suggesting its prolongation. </p> <p class="cuerpo"><b>Results:</b> 24 patients were included (19 male), diagnosed from lung cancer (n=15), head and neck, renal, bladder and colorectal cancer (n=2, each), melanoma (n=1). They were treated with Anti PD-1/PDL-1 mono therapy (n=18), combo with chemo (n=2), or combo with anti-CTLA4 (n=2). Three patients had G1 colitis and two, >=G2, all treated with anti-PD1 and before 6th cycle, as described on literature. ROC curve presents AUC 0,559 (CI95%:0,32-0,798) and RR for colitis taking FC value is 1,001 for each 10 units (p=0,493).</p> <p class="cuerpo"><b>Conclusion:</b> Even though we must take into account the limitations of the study we cannot conclude that FC could be used as a predictor for detecting immune-mediated colitis. </p>
Data from: Association of high-sensitivity cardiac troponin T with mortality and cardiovascular events in a community-based prospective study in Beijing
Objective: The prognostic value of cardiac troponins in apparently healthy populations is not well established. The aim of this study was to investigate the prognostic properties of high-sensitivity cardiac troponin T (hs-cTnT) for long-term adverse outcomes. Setting: A community-dwelling prospective survey of residents from two communities in Beijing. Participants: From September 2007 to January 2009, 1680 participants were initially enrolled. Of these, 1499 (870 females, mean age: 61.4 years) participants completed the survey and were followed up for a median of 4.8 years (interquartile range: 4.5–5.2). Outcome measures: The primary outcome was the occurrence of all-cause mortality and major cardiovascular events. Results: Overall, 820 individuals (54.7%) had detectable hs-cTnT levels. During the follow-up, 52 participants (3.5%) died, 154 (10.3%) had major cardiovascular events, and 99 (6.6%) experienced new-onset coronary events. Compared with those with undetectable hs-cTnT levels, participants with hs-cTnT levels in the highest category(≥14 ng/L) had a significantly increased risk for all-cause mortality (adjusted hazard ratio [aHR] : 2.07, 95% confidence interval [CI]: 1.05–3.01), major cardiovascular events (aHR: 3.27, 95% CI: 1.88–5.70), and coronary events (aHR: 4.50, 95% CI: 2.26–9.02) in covariate-adjusted analyses. No differences in stroke incidence were found (aHR: 1.27; 95% CI: 0.69–2.62). Also, significant associations were presented when hs-cTnT levels were modelled as a continuous variable and when analysing changes in hs-cTnT levels over time with adverse outcomes. The addition of troponin T levels to clinical variables led to significant increases in risk prediction with a marked improvement in the c-statistic (P=0.003 or lower). Conclusions: In this cohort of individuals from a community-based population, cardiac troponin T levels measured with a highly sensitive assay were associated with increases in the subsequent risk for all-cause mortality and major cardiovascular events. These results might support screening for at-risk individuals.
