Background: The increase in life expectancy is accompanied by a growing number of elderly subjects affected by chronic comorbidities, a health issue which also implies important socioeconomic consequences. Shifting from hospital or community dwelling care towards a home personalized healthcare paradigm would promote active aging with a better quality of life, along with a reduction in healthcare-related costs. Objective: The aim of the SMARTA project was to develop and test an innovative personal health system integrating standard sensors as well as innovative wearable and environmental sensors to allow home telemonitoring of vital parameters and detection of anomalies in daily activities, thus supporting active aging through remote healthcare. Methods: A first phase of the project consisted in the definition of the health and environmental parameters to be monitored (electrocardiography and actigraphy, blood pressure and oxygen saturation, weight, ear temperature, glycemia, home interaction monitoring - water tap, refrigerator, and dishwasher), the feedbacks for the clinicians, and the reminders for the patients. It was followed by a technical feasibility analysis leading to an iterative process of prototype development, sensor integration, and testing. Once the prototype had reached an advanced stage of development, a group of 32 volunteers - including 15 healthy adult subjects, 13 elderly people with cardiac diseases, and 4 clinical operators - was recruited to test the system in a real home setting, in order to evaluate both technical reliability and user perception of the system in terms of effectiveness, usability, acceptance, and attractiveness. Results: The testing in a real home setting showed a good perception of the SMARTA system and its functionalities both by the patients and by the clinicians, who appreciated the user interface and the clinical governance system. The moderate system reliability of 65-70% evidenced some technical issues, mainly related to sensor integration, while the patient's user interface showed excellent reliability (100%). Conclusions: Both elderly people and clinical operators considered the SMARTA system a promising and attractive tool for improving patients' healthcare while reducing related costs and preserving quality of life. However, the moderate reliability of the system should prompt further technical developments in terms of sensor integration and usability of the clinical operator's user interface.

Inflammation is associated with atrial fibrillation (AF), but little is known about the association of AF with the inflammatory serum cytokines after the acute postoperative phase. Thus, we aimed to explore how plasma cytokines concentrations modify during a 3-week cardiac rehabilitation after heart surgery, comparing patients who developed postoperative AF (POAF) and those with permanent AF with patients free from AF (NoAF group). We enrolled 100 consecutive patients and 40 healthy volunteers as a control group. At the beginning of cardiac rehabilitation, 11 days after surgery, serum levels of MPO, PTX3, ADAM17, sST2, IL-25, and IL-33 were dramatically higher, whereas TNFα and IL-37 levels were much lower in NoAF, POAF, and permanent AF patients than in the healthy volunteers. After rehabilitation, most of the cytokines changed tending towards normalization. POAF patients (35% of the total) had higher body mass index and abdominal adiposity than NoAF patients, but similar general characteristics and risk factors for POAF. However, ADAM-17 and IL-25 were always lower in POAF than in NoAF patients, suggesting a protective role of IL-25 and ADAM 17 against POAF occurrence. This finding could impact on therapeutic strategies focusing on the postoperative prophylactic antiarrhythmic interventions. Cardiac surgery is frequently complicated by postoperative atrial fibrillation (POAF), which is associated with increased morbidity and costs 1,2. POAF occurs in a third of patients undergoing cardiac bypass surgery 3 and up to 40% of patients undergoing valvular surgery 4 , usually within the first three days after the intervention. Post-operative atrial arrhythmias can also occur after non-cardiac surgery, especially after thoracic and large abdominal surgery, but with lower incidence 5. Previous studies have demonstrated that inflammation is closely related to the pathogenesis of atrial fibrillation (AF) 6 and there is strong evidence supporting an association between inflammation and AF. The inflammatory cardiac diseases, such as myocarditis, are known to be associated with an increased incidence of arrhythmia, including AF 7. Cardiac surgery is an acute stressful event generating a chain of inflammatory reactions, as a consequence of the aortic clamp, the organ reperfusion injury during cardiopulmonary bypass for extracorporeal circulation and the surgical injury itself. The underlying inflammatory pathway involves leukocyte activation 8. The inflammatory cascade after the surgery, represented by many circulating cytokines, may play a prominent role in initiating POAF. In fact, the cytokines, a network of intracellular proteins produced by lymphocytes, monocytes, and macrophages in response to inflammatory stimuli, have been assessed as potential mediators in the occurrence of AF 9. While a few studies evaluated the concentrations of biohumoral markers of inflammation perioperatively, very little is known about the serum levels of cytokines after the acute post-operative phase, i.e. some days after surgery when the pat...

Results suggest the more correct administration of pegfilgrastim as primary prophylaxis and timing start, compared to filgrastim/lenograstim. In secondary prophylaxis, the use of granulocyte colony-stimulating factors is extended beyond guideline recommendations to support patients at high risk of febrile neutropenia and to guarantee dose intensity. These outcomes suggest both the need of educational activities and the development of predictive tools to better define high risk patients and the use of granulocyte colony-stimulating factors.

Heart transplant (HTx) and left ventricular assist device (LVAD) implant are the best options for symptomatic end stage heart failure, but LVAD patients show lower rehabilitative outcome than HTx patients. To investigate the causes, we compared biomarkers levels and their association with rehabilitative outcome in 51 HTx and in 46 LVAD patients entering the same cardiac rehabilitation program. In both groups, routine biomarkers were measured at start (T1) and end (T2) of cardiac rehabilitation while homocysteine, leptine and IGF-1 were measured at T1 only. HTx patients had lower lymphocyte, platelets, glucose, total proteins and albumin at T1; differences with LVAD patients vanished during rehabilitation when new cases of diabetes were observed in HTx. By contrast, total cholesterol, LDL and HDL fractions, leptin and IGF-1 were higher in HTx patients. The increase from T1 to T2 in six-minute walking test distance, measure of functional rehabilitation outcome, was positively associated with homocysteine and IGF-1 levels in HTx patients. In conclusion, during rehabilitation care should be paid to the early occurrence of dyslipidemia and hyperglycemia in HTx patients, which also require a proper protein dietary support. IGF-1, dangerously low in LVAD patients, might contribute to their lower rehabilitative outcome.
