At visit 4 and visit 6, following Folch extraction of the lipid moiety from plasma enrichment of 13C palmitate in NEFA and TAG pool will be measured by GCMS. The isotopic data for [13C] palmitate will be used to calculate the tracer concentration of [13C] palmitate in NEFA and TAG pool. • TAG concentration will be measured as AUC (0-240 minutes), AUC (0-360 minutes), AUC (0-480) and mean of last three points 420, 450 and 480 minutes. • The tracer concentration of [13C] palmitate in NEFA and TAG pool, will be measured as (AUC 0-240) minutes and AUC (0-480 minutes) and mean of last three points 420, 450 and 480 minutes.

At visit 4 and visit 6, perchloric acid treated plasma from the studies will be used to extract BOHB and the enrichment of 13C BOHB will be measured by GCMS. The isotopic data for 3-hydroxybutyrate will be used to calculate the relative partitioning of systemic plasma NEFA into [13C] 3-hydroxybutyrate as the ratio of [13C] 3-hydroxybutyrate to [13C] palmitate (in NEFA and TAG pool) in the plasma, where [13C] is expressed in micromol/L. The ratio of [13C] 3-hydroxybutyrate to [13C] palmitate (in TAG pool) in the plasma will be calculated, where [13C] is expressed in micromol/l measured as AUC (0-240 minutes), AUC (0-360 minutes), AUC (0-480 minutes) and mean of last three points 420, 450 and 480 minutes.

At visit 4 and visit 6, the concentration of Glucagon, insulin and cortisol will be measured by RIA. Ratio of glucagon to insulin concentration will be measured as AUC (0-240 minutes), AUC (0-360 minutes), AUC (0-480) and mean of last three points 420, 450 and 480 minutes. The data will be compared following 4-weeks dapagliflozin versus placebo treatment.

At visit 4 and visit 6, the cardiac output responses investigated using Echocardiogram will be compared following 4-weeks dapagliflozin versus placebo treatment.

At visit 4 and visit 6, aortic pulse wave velocity (m/s) will be measured by Vicorder between a cuff placed on the leg and around the neck. The data will be compared following 4-weeks dapagliflozin versus placebo treatment.

At visit 4 and visit 6, targeted metabolomics will be used to measure 188 species from the metabolome including 40 species of acyl carnitines at 480 minutes. The data will be compared following 4-weeks dapagliflozin versus placebo treatment.

To conduct the exercise to the inspiratory muscles was used for IMT Threshold ® device (Threshold Inspiratory Muscle Trainer, HealthScan Products Inc., Cedar Grove, New Jersey) is one of the most used for training of inspiratory muscles in patients with several pathologies such as ICC.Threshold ® has been engaged in the patient's mouth by a mouthpiece, with the nose occluded by a nose clip. The exercise time was 3 minutes. During this period, participants were encouraged to only breathe through the mouth and maintain a respiratory rate between 12 and 16ipm. The exercise would be stopped if HR increased more than 20% and / or SpO2 < 88%.

The POE (BTS Bioengineering, Italy) measures the volume changes of thoracoabdominal system through placement of 89 markers formed by hemiesferas covered with retro-reflective paper, taking the place of each of these hemiesferas determined by anatomical landmarks in anterior and posterior thorax and abdomen.

To assess the functional capacity test was used for 6-minute walk (6MWT) according to the protocol established by the American Thoracic Society (ATS). Before the test parameters were assessed resting blood pressure (BP), Heart Rate (HR), Oxygen Saturation (SpO2 - pulse oximetry portable Onix 9500), Respiratory Frequency (RF) and dyspnea scale (scale Borg).

Region of Enrollment

Number of normally fertilized oocytes (2PNs) divided by the total number of oocytes collected (i.e., not just the number of inseminated MII oocytes). This accounted for the possibility of both an enhanced oocyte maturation and improved fertilization of the mature oocytes. This also permitted inclusion of both IVF and intracytoplasmic sperm injection (ICSI) cycles in a way that allowed for evaluation of collective fertilization rates (i.e., typically, the denominator in IVF in calculating fertilization rate is all eggs collected, but in ICSI it is calculated using only the number of MII oocytes injected).
