Abstract Background The intraventricular pressure differences (IVPD) IVPD using color M-mode is a specific marker in infants of mothers with gestational diabetes mellitus (GDM). (Circulation R 2019, 378–388). Purpose This study investigated the myocardial performance of fetuses in mothers with GDM under the new GDM definition. Method The study population comprised of 27 mothers with GDM and the fetus. Women with GDM were defined as those with a glucose metabolism abnormality that existed before or began during the current pregnancy and was diagnosed using OGTTs. The 5 mothers with type 1 or type 2 DM were receiving insulin before their pregnancy. Fetal echo measurements were performed about median gestational age 35 weeks. The primary outcomes were comparisons of the fetal myocardial performance of GDM with insulin administration and without administration using echocardiography with IVPD, and IVPG. The secondary outcome has investigated the relationships between echocardiography parameters, IVPD, and IVPG, and maternal factors. For all statistical analyses, P<0.05 was considered significant. Result In the insulin group was higher RV output (Fig. 2A). Maternal max HbA1c was observed to have a positive correlation with fetal RV output, significantly (Fig. 2B). Maternal max fasting blood glucose was observed to have a negative correlation with the Total, Basal and Mid to apical IVPD, significantly, respectively. Serial change of LV Total IVPD from fetal to after birth shown in Slide. In both groups, LV Total IVPD was increasing from fetal and after birth significantly. Conclusion The mechanism associated with the favorable systolic and diastolic performances in IGDMs is suggested to involve metabolic adaptations in the heart. In diabetic mice, these adaptations seem to prevent the heart from failing during conditions of pressure overload, suggesting a restoration of the balance between glucose and fatty acid utilization is beneficial for cardiac function. In fetal LV and RV-IVPD might be interacted the mother's blood sugar control. These indexes can predict the sensitive fetal and infant's cardiac dysfunction for GDM.

Backgrounds: Controlled heart rate (HR) and increased pulse pressure (PP) are related to better outcomes in stable heart failure. Hemodynamic response to stress evaluated by an acute hemodynamics index (AHI), the product of HR and PP, has been reported to be associated with poor outcomes in patients admitted for acute decompensated heart failure (ADHF). However, there is no information available on the long-term prognostic value of the serial change of AHI during hospitalization in patients admitted for ADHF. Methods and Results: We studied 259 patients admitted for ADHF and discharged with survival. We measured AHI (HR x PP/1000) at admission and discharge. AHI significantly decreased from admission to discharge (6.98±3.04 to 3.81±1.21 bpm·mmHg, p<0.0001). During a mean follow-up period of 5.0±3.2 yrs, 53 patients had cardiac death. The change [ad-dis] of AHI from admission to discharge (AHI[ad-dis]) was significantly less in patients with than without cardiac death (1.98±2.17 vs 3.47±2.87 bpm·mmHg, p=0.0005). Multivariate Cox regression analysis revealed that AHI[ad-dis], but not PP[ad-dis], was significantly associated with cardiac death, independently of prior heart failure hospitalization, body mass index, estimated glomerular filtration rate, hemoglobin level and left ventricular end-diastolic dimension. ROC analysis revealed that AUC in AHI[ad-dis](0.668[0.588-0.749]) was greater than that in PP[ad-dis](0.637[0.572-0.717]). Patients with less AHI[ad-dis] (≤1.79 bpm·mmHg by ROC analysis) had a significantly higher risk of cardiac death than those with greater AHI[ad-dis] (adjusted hazard ratio: 3.19[1.77 to 5.76], 30% vs 13%, p<0.0001). Conclusions: Cardiac death was frequently observed in ADHF patients who had less degree of the decrease in AHI during hospitalization. The change of AHI during hospitalization would be a simple and useful marker for risk stratification in patients admitted for ADHF.

BackgroundA randomised controlled trial in Japan showed that inhaled N-acetylcysteine monotherapy stabilised serial decline in forced vital capacity (FVC) in some patients with early idiopathic pulmonary fibrosis (IPF). However, the efficacy and tolerability of combination therapy with an antifibrotic agent and inhaled N-acetylcysteine are unknown.MethodsThis 48-week, randomised, open-label, multicentre phase 3 trial compared the efficacy and tolerability of combination therapy with pirfenidone plus inhaled N-acetylcysteine 352.4 mg twice daily with the results for pirfenidone alone in patients with IPF. The primary end-point was annual rate of decline in FVC. Exploratory efficacy measurements included serial change in diffusing capacity of the lung for carbon monoxide (DLCO) and 6-min walk distance (6MWD), progression-free survival (PFS), incidence of acute exacerbation, and tolerability.Results81 patients were randomly assigned in a 1:1 ratio to receive pirfenidone plus inhaled N-acetylcysteine (n=41) or pirfenidone (n=40). The 48-week rate of change in FVC was −300 mL and −123 mL, respectively (difference −178 mL, 95% CI −324–−31 mL; p=0.018). Serial change in DLCO, 6MWD, PFS and incidence of acute exacerbation did not significantly differ between the two groups. The incidence of adverse events (n=19 (55.9%) for pirfenidone plus N-acetylcysteine; n=18 (50%) for pirfenidone alone) was similar between groups.ConclusionsCombination treatment with inhaled N-acetylcysteine and pirfenidone is likely to result in worse outcomes for IPF.

Abstract Introduction It is well known that catheter ablation (CA) for patients with atrial fibrillation (AF) improves their renal function. However, the precise mechanism of improving a renal function, such as a transition of the uremic toxin is unclear. Purpose Indoxyl sulfate (IS), a protein-bound uremic toxin, induces chronic kidney disease (CKD) and AF. This study aimed to investigate the transition of serum IS level in the AF patients with and without CKD after CA. Methods A total of 138 consecutive AF patients who underwent CA and maintained sinus rhythm were prospectively enrolled (age 65.5 ± 10.7 years, paroxysmal AF 67.4%). Patients were divided into 4 groups (non-CKD/low-IS:68, non-CKD/high-IS:28, CKD/low-IS:13, CKD/high-IS:29). CKD was defined as CKD stage III (estimated glomerular filtration rate (eGFR) 30-60 ml/min/1.73m2), and high-IS was defined according to the mean of IS (IS≥1.1 μg/ml) before CA. Plasma IS levels and eGFR were determined before and at 1 year after CA. We evaluated the relationship between the IS and eGFR after CA among the 4 groups. Results CA significantly improved the eGFR in patients with CKD (from 50.2 ± 5.7 to 55.4 ± 10.8 ml/min/1.73m2, p &lt; 0.001). The serum IS level in the patients with non-CKD/high-IS was significantly decreased (from 1.7 ± 0.7 to 1.1 ± 0.6 μg/ml, p &lt; 0.001). However, the serum IS level in the patients with CKD/high-IS was not improved (from 1.9 ± 0.9 to 1.7 ± 0.7 μg/ml, p = 0.22) and significantly higher than that in the others (p &lt; 0.001), regardless of improving their eGFR (Figure). Furthermore, the multiple regression analysis revealed that the ΔIS, between before and after CA, was independent of eGFR. Conclusion The change of IS in the patients with CKD was significantly different from that in those without CKD. In the patients with CKD, CA improved their eGFR, however, the serum level of IS, a protein-bound uremic toxin, was not improved after CA. Abstract P11 Figure. Serial Change of eGFR and IS
