Background: Nonalcoholic fatty liver disease (NAFLD) is an emerging risk factor for incident heart failure (HF). It is currently unknown whether NAFLD predicts all-cause mortality in patients admitted for acute HF. We aimed to assess whether NAFLD and its severity (diagnosed by ultrasonography and non-invasive fibrosis biomarkers) were associated with increased all-cause mortality in this particularly high-risk patient population. Methods: We studied 264 elderly patients, who were consecutively admitted for acute HF to the hospital between years 2013 and 2015, after excluding those with acute myocardial infarction, severe valvular heart diseases, kidney failure, cancer, cirrhosis of any etiology or known chronic liver diseases. Follow-up of patients continued until November 1, 2017. Results: Over a mean follow-up of 23.2 months (range: 1 day-58 months), there were 140 (53%) total deaths. Of these, 24 deaths occurred during the first hospital admission (in-hospital death) and 116 deaths occurred after the hospital discharge during the follow-up period. Patients with NAFLD at hospital admission had significantly higher cumulative incidence rates of in-hospital and post-discharge all-cause mortality (singly or in combination) compared with those without NAFLD. This mortality risk was particularly high among patients with advanced NAFLD fibrosis. In Cox regression analysis, NAFLD was associated with an increased risk of all-cause mortality (adjusted-hazard ratio 1.82, 95% confidence intervals 1.22–2.81, p < 0.005) even after adjustment for established risk factors and potential confounding variables. Conclusions: NAFLD and its severity were independently associated with increased risk of in-hospital and post-discharge all-cause mortality in elderly patients admitted for acute HF.

Nonalcoholic fatty liver disease (NAFLD) is an emerging risk factor for heart failure (HF). Although some progress has been made in improving survival among patients admitted for HF, the rates of hospital readmissions and the related costs continue to rise dramatically. We sought to examine whether NAFLD and its severity (diagnosed at hospital admission) was independently associated with a higher risk of 1-year all-cause and cardiac re-hospitalization in patients admitted for acute HF. We studied 212 elderly patients who were consecutively admitted with acute HF to the Hospital of Negrar (Verona) over a 1-year period. Diagnosis of NAFLD was based on ultrasonography, whereas the severity of advanced NAFLD fibrosis was based on the fibrosis (FIB)-4 score and other non-invasive fibrosis scores. Patients with acute myocardial infarction, severe valvular heart diseases, endstage renal disease, cancer, known liver diseases or decompensated cirrhosis were excluded. Cox regression was used to estimate hazard ratios (HR) for the associations between NAFLD and the outcome(s) of interest. The cumulative rate of 1-year all-cause re-hospitalizations was 46.7% (n = 99, mainly due to cardiac causes). Patients with NAFLD (n = 109; 51.4%) had remarkably higher 1-year all-cause and cardiac re-hospitalization rates compared with their counterparts without NAFLD. Both event rates were particularly increased in those with advanced NAFLD fibrosis. NAFLD was associated with a 5-fold increased risk of 1-year all-cause re-hospitalization (adjusted-hazard ratio 5.05, 95% confidence intervals 2.78-9.10, p

In the last years, there has been a big development of European policies and regulations on energy saving topics. This is due to the will to reach the targets of 20-20-20. Buildings consume a lot of energy, so the legal framework related to the reduction of energy consumption in this sector has had a huge evolution. The "NZEB (nearly zero energy building)" concept was introduced in 2010, eight years after the release of the original EPBD (energy performance of buildings directive). By 2020, all new buildings and buildings that are subject to renovation should have very low energy consumption, covered for the major part by renewable sources. Designing and realizing this kind of building is a very ambitious task, which needs to be supported by appropriate tools and software. This paper presents a new tool for assessing building performance, named BENIMPACT Suite (building's environmental impact evaluator and optimizer), which is developed by EnginSoft (Italy). The suite is organized in different core modules that allow to verify how the building performance level is influenced by different design choices, such as envelope shape and materials, plant systems, renewable sources use, etc.. One of the test cases used to validate the BENIMPACT Suite energy performance is the evaluation of an interesting Italian ZEB, finished in 2010 and called CasaZeroEnergy. It is located in Felettano (Udine), a small town in northeastern Italy. This building is an experimental house designed and monitored by the Laboratory of Building Design of the University of Trento (Italy) and built by Polo Le Ville Plus Group (Cassacco-Italy). The energy performance of this building was modelled and evaluated using BENIMPACT Suite, and simulation results were compared with monitored data.

Repeat hospitalization due to acute heart failure (HF) is a global public health problem that markedly impacts on health resource use. Identifying novel predictors of rehospitalization would help physicians to determine the optimal postdischarge plan for preventing HF rehospitalization. Nonalcoholic fatty liver disease (NAFLD) is an emerging risk factor for many heart diseases, including HF. We assessed whether NAFLD at hospital admission predicts 1-year all-cause rehospitalization in patients with acute HF. We enrolled all patients consecutively admitted for acute HF to our General Medicine Division, from January 2013 to April 2014, after excluding patients with acute myocardial infarction, severe heart valve diseases, malignancy, known liver diseases, and those with volume overload related to extracardiac causes. NAFLD was diagnosed by ultrasonography and exclusion of competing etiologies. The primary outcome of the study was the 1-year all-cause rehospitalization rate. Among the 107 patients enrolled in the study, the cumulative rehospitalization rate was 12.1% at 1 month, 25.2% at 3 months, 29.9% at 6 months, and 38.3% at 1 year. Patients with NAFLD had markedly higher 1-year rehospitalization rates than those without NAFLD (58% vs 21% at 1 y; P
