Abstract
Diabetes mellitus is a metabolic disorder with global economic implications that can lead to complications such as diabetic cardiomyopathy. The aim of this study was to compare the effects of chitosan versus dapagliflozin in mouse diabetic cardiomyopathy. We used 32 C57Bl/6 male mice aged between 8 and 10 weeks, which were randomly divided into Control-without diabetes mellitus (DM), type 1 DM (T1DM), T1DM + Chitosan, and T1DM + Dapapgliflozin groups. We induced diabetes with streptozotocin and treated the animals for 12 weeks. The analysis showed a reduction in intramyocardial fibrosis in the T1DM + Dapapgliflozin compared to T1DM animals. In T1DM + CHIT, a reduction in intramyocardial fibrosis was observed although, accordingly, there was also no significant decrease in blood glucose. The level of oxidative stress was reduced in the groups of treated animals compared to T1DM. All these observed changes in the structure and function of hearts were highlighted in the echocardiographic examination. In the treated groups, there was delayed appearance of left ventricular (LV) hypertrophy, a slight decrease in the ejection fraction of the LV, and an improved diastolic profile. The results demonstrate that chitosan has promising effects on diabetic cardiomyopathy that are comparable to the beneficial effects of dapagliflozin.

Abstract
(1) Background: Measures for the control of diabetes mellitus (DM) and, especially, for the control of its complications represent a main objective of the research carried out on this disease, since both mortality and morbidity relating to DM represent real problems for the health system worldwide. The aim of our study was to evaluate nervous tissue from the heart and kidneys of mice with diabetes induced by streptozotocin (STZ) in the presence or absence of dapagliflozin (DAPA) treatment. (2) Methods: For this purpose, we used 24 C 57Bl/6 male mice, aged between 8 and 10 weeks. The mice were divided into three groups: sham (DM-), control (DM+), and treated (DM+). Diabetes mellitus was induced by injecting a single intraperitoneal dose of STZ. The duration of diabetes in the mice included in our study was 12 weeks after STZ administration; then, the heart and kidneys were sampled, and nervous tissue (using the primary antibody PGP 9.5) from the whole heart, from the atrioventricular node, and from the kidneys was analyzed. (3) Results: The density of nerve tissue registered a significant decrease in animals from the control group (DM+), to a value of 0.0122 ± 0.005 mm2 nerve tissue/mm2 cardiac tissue, compared with the sham group (DM-), wherein the value was 0.022 ± 0.006 mm2 nervous tissue/mm2 cardiac tissue (p = 0.004). Treatment with dapagliflozin reduced the nerve tissue damage in the treated (DM+DAPA) group of animals, resulting in a nerve tissue density of 0.019 ± 0.004 mm2 nerve tissue/mm2 cardiac tissue; a statistically significant difference was noted between the control (DM+) and treated (DM+DAPA) groups (p = 0.046). The same trends of improvement in nerve fiber damage in DM after treatment with DAPA were observed both in the atrioventricular node and in the kidneys. (4) Conclusions. These data suggest that dapagliflozin, when used in streptozotocin-induced diabetes in mice, reduces the alteration of the nervous system in the kidneys and in the heart, thus highlighting better preservation of cardiac and renal homeostasis, independent of any reduction in the effects of hyperglycemia produced in this disease.

Abstract
Triple-chamber cardiac devices are utilized for cardiac resynchronization therapy (CRT) and is the standard-of-care therapy for heart failure (HF) patients in the current guidelines. In the setting of biventricular (BIV) pacing it involves a mandatory implantation of right ventricular (RV) lead that allows simultaneous BIV pacing with 0 ms VV (ventricular to ventricular) interval. Nevertheless, it seems that response to CRT is not related to RV lead position. RV pacing is known for deleterious effects on RV/Left Ventricle (LV) function and should not be used in persons with normal atrioventricular conduction (AV) and sinus rhythm. As it compensates for the additional asynchrony induced by unnecessary stimulation of RV pacing, only pacing the left ventricle (LV) may result in improved cardiac resynchronization therapy (CRT) outcomes and a decrease in the number of individuals who do not respond to the procedure. Furthermore, leadless LV fusion CRT pacing without RV lead could be a potential CRT therapy alternative to BIV pacing in nonischemic heart failure patients with preserved AV conduction. The aim of our study is to made an update in cardiac resynchronization therapy with LV only fusion pacing.

Abstract
The aim of our study is to provide an assessment of heart rate variability (HRV) as a predictor for the survival of patients with pancreatic cancer (PCa). We conducted a retrospective, descriptive study. 53 consecutive patients who were newly diagnosed with pancreatic cancer (PCa), were included. In the end, 41 patients were included in the analysis, out of which 14 patients survived at least until the 24-month follow-up, while 27 patients died within 24 months from the diagnosis. These patients were monitored with 24-hour Holter electrocardiogram (ECG) prior to the initiation of any therapy for determining heart rate variability. To establish the cut-off values of HRV, 24-hour Holter ECG recordings of 20 healthy subjects were analyzed. In addition to heart rate analysis, HRV indices were also analyzed: SDNN, rMSSD, ULF and VLF. Median survival in patients with low value of SDNN was 9 months, compared to patients with hight SDNN where median survival was 15 months (Hazard ratio 2.301, 95% CI of ratio 0.9080 to 5.833, p= 0.034). Although low values of the HRV indices in the frequency domain were associated with reduced survival, no statistically significant differences were recorded. The reduction of heart rate variability indices is a negative prognostic factor in patients newly diagnosed with pancreatic cancer.

Abstract
BACKGROUND Remote monitoring (RM) is becoming a standard of care for patients with cardiac resynchronization therapy (CRT). This technology combines the use of pacemakers or implantable cardioverter-defibrillators (ICD) and wireless communication to provide physicians with continuous, real-time information on the patient's cardiac activity. The purpose of the study was to evaluate if the remote monitoring technology in the follow-up CRT patients is feasible and safe. METHODS A total of nine patients were enrolled in the study, implanted with a CRT system with wireless transmission capabilities. Immediately after the procedure received the RM, were enrolled in the virtual clinic and instructed by the doctor how to use the device at home. Regular virtual transmissions were made automatically every 3 weeks, respecting optimal transmission conditions. The accumulation of fluid in the lungs, atrial or ventricular tachyarrhythmia together with system integrity automatically activate alerts. RESULTS One hundred and one transmissions were collected and analyzed from the virtual ward. Average follow-up was 7.7±4.8 months, longest follow-up was 18 months. None of the patients experienced complications during the study period, with three of them being follow-up solely through telemetric means by implanting physician. Treatment optimization was successfully conducted via phone consultations, when necessary, without any adverse events. CONCLUSIONS The results of our study suggest that RM could be integrated into routine CRT management protocols, enhancing patients care and resource utilization.
