  AIM: The noninvasive tests (NITs) Agile 3+ and Agile 4 effectively identify patients with nonalcoholic fatty liver disease (NAFLD) complicated with advanced fibrosis (F3-4) and cirrhosis (F4), respectively. Little information is available on associations between Agile scores and intra-/extrahepatic events. The aim of this study was to determine the predictive performance of Agile scores for intra-/extrahepatic events in Asian patients with biopsy-proven NAFLD. METHODS: We undertook a retrospective multicenter cohort study to investigate associations between intra-/extrahepatic events and two Agile scores, Agile 3+ and Agile 4. The scores were obtained by combining clinical parameters and liver stiffness measurement using transient elastography. RESULTS: Among 403 enrolled patients, 11 had liver-related events (LREs), including seven with hepatocellular carcinoma (HCC). The incidence of LREs and HCC showed a stepwise increase in the advanced fibrosis group (F3-4), Agile 3+ rule-in (F3-4, highly suspected), and Agile 4 rule-in (F4, highly suspected) groups, compared to their counterparts. Hazard ratios for LREs in the advanced fibrosis group, Agile 3+ rule-in, and Agile 4 rule-in groups were 4.05 (p = 0.03), 23.5 (p = 0.003), and 45.5 (p < 0.001), respectively. The predictive performance results for Agile 3+ and Agile 4 were 0.780 and 0.866, respectively, which were higher than for fibrosis (0.595). Unlike for LREs, Agile scores failed to identify patients with extrahepatic events, including cardiovascular events and extrahepatic cancer. CONCLUSIONS: Agile 3+ and Agile 4 scores are excellent NITs for predicting LREs in patients with NAFLD, possibly without histological assessment.

  　View Summary

  Elevation of the ST segment after percutaneous coronary intervention (PCI) using rotational atherectomy (RA) for severely calcified lesions often persists after disappearance of the slow-flow phenomenon on angiography. We investigated clinical factors relevant to prolonged ST-segment elevation following RA among 152 patients with stable angina undergoing elective PCI. PCI procedures were divided into two strategies, RA without (primary RA strategy) or with (secondary RA strategy) balloon dilatation before RA. Incidence of prolonged ST-segment elevation after disappearance of slow-flow phenomenon was higher in the 56 patients with primary RA strategy (13%) than in the 96 patients with secondary RA strategy (3%, p = 0.039). Univariate logistic regression analysis showed levels of low-density lipoprotein cholesterol (LDL-C) (odds ratio [OR] 0.95, 95% confidence interval [CI] 0.93-0.99; p = 0.013), levels of triglycerides (OR 0.97, 95%CI 0.94-0.99; p = 0.040), and secondary RA strategy (OR 0.23, 95% CI 0.05-0.85; p = 0.028) were inversely associated with occurrence of prolonged ST-segment elevation following ablation. However, hemodialysis, diabetes mellitus, left-ventricular ejection fraction, lesion length ≥ 20 mm, and burr size did not show significant associations. Multivariate logistic regression analysis modeling revealed that secondary RA strategy was significantly associated with the occurrence of prolonged ST-segment elevation (Model 1: OR 0.24, 95% CI 0.05-0.95, p = 0.042; Model 2: OR 0.17, 95% CI 0.03-0.68, p = 0.018; Model 3: OR 0.21, 95% CI 0.03-0.87, p = 0.041) even after adjusting for levels of LDL-C and triglycerides. Secondary RA strategy may be useful to reduce the occurrence of prolonged ST-segment elevation following RA.

  　View Summary

  There are few reports on the long-term clinical outcome after percutaneous coronary intervention (PCI) in patients with stable coronary artery disease (CAD) complicated with frailty. This novel study investigated the association between pre-PCI frailty and long-term clinical outcomes in elderly patients aged 65 years or older with stable CAD who underwent elective PCI. We assessed 239 consecutive patients aged 65 years or older with stable CAD who underwent successful elective PCI at Kagoshima City Hospital between January 1st, 2017 and December 31st, 2020. Frailty was retrospectively assessed using the Canadian Study and Aging Clinical Frailty Scale (CFS). Based on the pre-PCI CFS, patients were divided into two groups: the non-frail (CFS < 5) and the frail (CFS ≥ 5) group. We investigated the association between pre-PCI CFS and major adverse cardiovascular events (MACEs) defined as the composite of all-cause death, non-fatal myocardial infarction, non-fatal stroke, and heart failure requiring hospitalization. Additionally, we assessed the association between pre-PCI CFS and major bleeding events defined as Bleeding Academic Research Consortium (BARC) type 3 or 5 bleeding. The mean age was 74.8 ± 7.0 years, and 73.6% were men. According to the pre-PCI frailty assessment, 38 (15.9%) and 201 (84.1%) were classified as frail and non-frail groups, respectively. During a median follow-up of 962 (607-1284) days, 46 patients developed MACEs and 10 patients developed major bleeding events. Kaplan-Meier curves showed a significantly higher incidence of MACE in the frail group compared to those in the non-frail group (Log-rank p < 0.001). Even in multivariate analysis, pre-PCI frailty (CFS ≥ 5) was independently associated with MACE (HR 4.27, 95% CI 1.86-9.80, p-value: < 0.001). Additionally, the cumulative incidence of major bleeding events was significantly higher in the frail group than in the non-frail group (Log-rank p = 0.001). Pre-PCI frailty was an independent risk factor for MACE and bleeding events in elderly patients with stable CAD who underwent elective PCI.

  BACKGROUND: Living alone as a proxy for social isolation has been considered to increase the risk of cardiovascular disease. We thus investigated the impact of living alone on mortality in acute myocardial infarction (AMI) patients. METHODS: Subjects comprised 277 AMI patients who underwent percutaneous coronary intervention (PCI). Associations between all-cause and cardiac deaths after PCI and baseline characteristics including living alone and Global Registry of Acute Coronary Events (GRACE) risk score were assessed. RESULTS: Eighty-three patients (30%) were living alone. Thirty patients died after PCI, including 20 cardiac deaths. Patients living alone showed higher incidences of both all-cause and cardiac deaths compared with patients not living alone (18% vs. 8%, P = 0.019 and 14% vs. 4%, P = 0.004). Multivariate Cox proportional hazards regression analysis models showed living alone [hazard ratio (HR), 2.60; 95% confidence interval (CI), 1.20-5.62; P = 0.016 and HR, 4.17; 95% CI, 1.60-10.84; P = 0.003] and GRACE risk score (HR, 1.02; 95% CI, 1.01-1.03; P = 0.003 and HR, 1.03; 95% CI, 1.01-1.04; P < 0.001) correlated significantly with all-cause and cardiac deaths. Cox proportional hazards modeling revealed that patients living alone with GRACE risk score ≥162 derived from the receiver-operating characteristic curve showed a significantly greater risk of all-cause death than patients not living alone with GRACE risk score <162 (HR 16.57; 95% CI 6.67-41.21; P < 0.001). CONCLUSION: Among AMI patients, living alone represents an independent risk factor for all-cause and cardiac deaths after PCI, separate from GRACE risk score. Furthermore, AMI patients living alone with high GRACE risk scores may experience an additively increased risk of mortality after PCI.

  OBJECTIVES: We performed our standard air leak, leak percentage, and cuff leak percentage tests in pediatric patients intubated with microcuff pediatric tracheal tubes (MPTTs) just before extubation. We examined the association between test findings and the subsequent occurrence of post-extubation laryngeal edema (PLE). DESIGN: Prospective, single-center, observational study. SETTING: PICU (June 1, 2020 to May 31, 2021). PATIENTS: Pediatric patients intubated and scheduled for extubation during the day shift in the PICU. INTERVENTIONS: Multiple pre-extubation leak tests were performed on each patient immediately before extubation. In our center, the standard leak test is positive if a leak is audible at 30 cm H 2 O applied pressure with the MPTT cuff deflated. Two other tests were calculated in the pressure control-assist control ventilator mode using the following formulas: leak percentage with deflated cuff = (inspiratory tidal volume [V t ]-expiratory V t ) × 100/inspiratory V t ; cuff leak percentage = (expiratory V t with inflated cuff-expiratory V t with deflated cuff) × 100/expiratory V t with inflated cuff. MEASUREMENTS AND MAIN RESULTS: The diagnostic criteria for PLE was made by at least two healthcare professionals and included upper airway stricture with stridor-requiring nebulized epinephrine. Eighty-five pediatric patients (< 15 yr) who had been intubated for at least 12 hours using the MPTT were included. Positive rates for the standard leak, leak percentage (cutoff 10%), and cuff leak percentage (cutoff 10%) tests were 0.27, 0.20, and 0.64, respectively. The standard leak, leak percentage, and cuff leak tests showed sensitivities of 0.36, 0.27, and 0.55, respectively; and specificities of 0.74, 0.81, and 0.35, respectively. PLE occurred in 11 of 85 patients (13%), and there were no instances of needing reintubation. CONCLUSIONS: The pre-extubation leak tests in current practice for intubated pediatric patients in the PICU all lack diagnostic accuracy for PLE.
