Observational Study
Cardiorespiratory function and VO2 kinetics after sleeve gastrectomy: a follow-up analysis.
Although poor cardiorespiratory function is a powerful predictor of mortality in patients with obesity, functional evaluation has been given little attention after laparoscopic sleeve gastrectomy (LSG). The aim of this study was thus to investigate the impact of LSG on functional capacity analysing a shorter and longer post-surgical follow-up. In this observational study, 24 patients with severe obesity (BMI 44.04 ± 5.84 kg/m2, age 47.0 ± 9.0 years) performed cardiopulmonary exercise testing 7 months pre-, 6 and 16 months post-LSG. ⋯ Although patients showed an improved peak work capacity after LSG, parameters of maximal absolute aerobic capacity demonstrated a significant decrease, which was confirmed also in the follow-up analysis. Furthermore, the time constant Tau (τ) of the fundamental component of VO2 kinetics was altered by LSG, however, within the 16 months of follow-up it returned towards baseline values. It can thus be concluded that LSG improved peak work capacity along with a lower maximal absolute aerobic capacity, which might be due to a loss of muscle mass and potentially impaired peripheral oxidative muscle metabolism. However, VO2 kinetics might suggest an initial restoration of peripheral oxidative muscle capacity after a longer follow-up.

For some years now, direct-acting oral anticoagulants (DOACs) have entered the clinical practice for stroke prevention in non-valvular atrial fibrillation (NVAF) or for prevention and treatment of venous thromboembolism (VTE). However, there is uncertainty on DOACs' use in some clinical scenarios that are not fully explored by clinical trials, but commonly encountered in the real world. We report a Delphi Consensus on DOAC use in VTE patients. ⋯ Votes 1-2 were considered as disagreement, while votes 3-5 as agreement. For each statement an agreement of ≥ 66% among the respondents was considered consensus. A brief discussion about the results for each topic is also reported.

Comparative Study
Characteristics of current heart failure patients admitted to internal medicine vs. cardiology hospital units: the VASCO study.
The majority of patients hospitalized for heart failure (HF) are admitted to internal medicine (IM) rather than to cardiology (CA) units, but to date few studies have analyzed the characteristics of these two populations. In this snapshot survey, we compared consecutive patients admitted for HF in six IM units vs. one non-intensive CA unit. During the 6-month survey period, 467 patients were enrolled (127 in CA, 27.2% vs. 340 in IM, 72.8%). ⋯ Medical treatments also significantly differed, according to patients' clinical and instrumental characteristics in each unit. This study demonstrates important differences between HF patients hospitalized in CA vs. IM, and the need for a greater interaction between these two medical specialties for a better care of HF patients.
