Background: Physiological assessments using fractional flow reserve (FFR) and resting full-cycle ratio (RFR) have been recommended for revascularization decision making. Previous studies have shown a 20% rate of discordance between FFR and RFR. In this context, the correlation between RFR and FFR in patients with renal dysfunction remains unclear. This study examined correlations between RFR and FFR according to renal function.Methods and Results: In all, 263 consecutive patients with 370 intermediate lesions were enrolled in the study. Patients were classified into 3 groups according to renal function: Group 1, estimated glomerular filtration rate (eGFR) ≥60 mL/min/1.73 m2; Group 2, 30 mL/min/1.73 m2≤eGFR<60 mL/min/1.73 m2; Group 3, eGFR <30 mL/min/1.73 m2. The discordance between FFR and RFR was assessed using known cut-off values for FFR (≤0.80) and RFR (≤0.89). Of the 370 lesions, functional significance with FFR was observed in 154 (41.6%). RFR was significantly correlated with FFR in all groups (Group 1, R2=0.62 [P<0.001]; Group 2, R2=0.67 [P<0.001]; Group 3, R2=0.46 [P<0.001]). The rate of discordance between RFR and FFR differed significantly among the 3 groups (Group 1, 18.8%; Group 2, 18.5%; Group 3, 42.9%; P=0.02).Conclusions: The diagnostic performance of RFR differed based on renal function. A better understanding of the clinical factors contributing to FFR/RFR discordance, such as renal function, may facilitate the use of these indices.

We examined the effect of oral intake of pure glucosylceramide derived from konjac extract on skin barrier function evaluated by transepidermal water loss (TEWL) in hairless mice with sodium dodecyl sulfate (SDS)-induced skin roughness. The difference of TEWL between SDS-treated site and untreated sites in the pure glucosylceramide-fed group was significantly lower than that in control group on day 14 of ingestion. We investigated interleukin-1α (IL-1α) production in the hairless mouse skin, and it was significantly lower in the glucosylceramide-fed group than that of control animals. This reduced IL-1α production should contribute to improvement of skin barrier function. To investigate the effect of oral intake of glucosylceramide in human, we conducted a randomized double-blind placebo-controlled study including 100 healthy subjects whose TEWL in cheek was relatively high. As a result, cheek TEWL was significantly lower in the test product group as compared with the control group in weeks 8 and 12 of ingestion (p=0.023 and p=0.002 respectively).

Background:Disease understanding in patients with congenital heart disease is important in transitional and lifelong care. This study aimed to develop the Japanese version of the Leuven Knowledge Questionnaire for Congenital Heart Disease (LKQCHD) and identify factors associated with disease-related knowledge.Methods and Results:After confirming the content and face validity of the scale, a questionnaire including the LKQCHD was distributed to 59 eligible patients aged >16 years attending a university hospital. For the 58 participants who responded (30 males, 28 females; median age 22 years), the mean (±SD) LKQCHD total score was 53.7±15.4, with mean (±SD) scores for each domain as follows: Disease and Treatment, 68.3±19.7; Preventing Complications, 45.8±19.0; Physical Activity, 74.1±34.1; Sex and Heredity, 37.9±35.4; and Contraception and Pregnancy, 40.2±29.1. Regarding known-groups validity, we found a positive correlation between the LKQCHD score and age (ρ=0.268, P=0.042), and a significantly low LKQCHD score in the moderate/severe disease group (η2=0.131, P=0.021). Regarding convergent validity, the LKQCHD score was positively correlated with the total and subscale scores of the Resilience Assessment Tool (r=0.213 [P=0.109] andr=0.405 [P=0.002], respectively).Conclusions:We confirmed the validity of the Japanese version of the LKQCHD, concluding that patient education regarding long-term complications, prevention methods, heredity, pregnancy, and childbirth is needed.
