Abstract
From the viewpoint of evaluating the instrumental performance of high-resolution electron microscopy (HREM), the Scherzer condition was investigated using information theory. As a result, the optimum defocus amount Δf can be expressed based on [Formula: see text] , and the formula [Formula: see text] is obtained. Furthermore, a procedure for measuring point resolution using the through-focus technique is developed, and a new method for determining the spherical aberration coefficient using the variance of Δf is introduced in the procedure.

Abstract
OBJECTIVES Accumulating evidence from cross-sectional studies suggests that the serum creatinine-to-cystatin C ratio (CCR) may be a useful biomarker for sarcopenia. This study aimed to assess the cross-sectional and longitudinal associations of CCR with sarcopenia and its parameters in community-dwelling older adults. DESIGN Cross-sectional and longitudinal study. SETTING AND PARTICIPANTS This 6-year prospective cohort study included the repeated measurement data from 1,253 Japanese residents (662 males and 591 females) aged ≥65 years who underwent medical checkups in Kusatsu and Hatoyama, Japan. A total of 4,421 observations were collected. MEASUREMENTS The CCR was grouped into quartiles by sex (Q1-Q4) using Q4 as the reference category. Sarcopenia was defined according to the Asian Working Group for Sarcopenia 2019 algorithm. Skeletal muscle mass index (SMI) measured using segmental multifrequency bioelectrical impedance analysis, handgrip strength (HGS), usual gait speed (UGS), and maximal gait speed (MGS) were measured repeatedly as sarcopenia parameters. The association of the CCR with changes in sarcopenia, SMI, HGS, UGS, and MGS during the 6-year period were analyzed using a generalized linear mixed-effects model. RESULTS The prevalence of sarcopenia at baseline was 13.1% (11.9% in males and 14.5% in females). In a cross-sectional analysis, the CCR quartile was inversely associated with sarcopenia and was positively associated with SMI, HGS, and MGS (P for trend < 0.001). In a longitudinal analysis during the 6 years, a significant increase in sarcopenia in Q2 (B = 1.1% point/year; P = 0.026 for group-by-time interaction) and significant declines in SMI (B = -0.01 kg/m2/year; P = 0.044 for group-by-time interaction) and MGS (B = -0.008 m/sec/year; P = 0.041 for group-by-time interaction) in Q1 were observed compared with Q4. However, the dose-response relationship was significant only for MGS (P = 0.033 for trend). No significant group-by-time interaction was observed for HGS. CCR was not significantly associated with UGS either cross-sectionally or longitudinally. CONCLUSIONS CCR is a useful biomarker regarding the status of sarcopenia. It may be used for sarcopenia screening even in older adults whose physical function is difficult to assess. However, further longitudinal studies are needed to determine whether CCR can be a predictor of future sarcopenia.

Abstract
Abstract
Background
Balloon pulmonary angioplasty (BPA) would be promising treatment option for non-operable chronic thromboembolic pulmonary hypertension (CTEPH). However, BPA for CTEPH with Chronic obstructive pulmonary disease (COPD) might exacerbate ventilation perfusion mismatch. The aim is to evaluate the efficacy and safety of BPA for CTEPH with moderate or severe COPD.
Method
Data from 149 CTEPH patients were collected retrospectively who underwent BPA from March 2011 to June 2021. Patients were divided according to the comorbidity of COPD: a COPD group (defined as forced expiratory volume in one second (FEV1.0) / forced vital capacity (FVC)<70% and FEV1.0<80% predicted [n=32]) or a non-COPD group [n=101]. Mild COPD patients (n=16) were excluded. Hemodynamics and respiratory parameters were compared.
Results
Hemodynamics improved similarly in both group (percent decrease of pulmonary vascular resistance; −61.1±12.3% in a COPD group, −65.8±11.1% in a non-COPD group, p=N.S). Patients in a COPD group showed improved respiratory function and oxygenation with FEV1.0% from 61.8±7.0% to 66.5±10.2% (p=0.02), and partial pressure of arterial oxygen from 60.9±10.6mmHg to 69.3±13.6mmHg (p<0.01). Higher vital capacity (r2=0.123, p=0.024), higher diffusing capacity for lung carbon monoxide (r2=0.308, p=0.028) at baseline were correlated with larger improvement of oxygenation after BPA in multivariate linear analyses. Lung injury per session was 1.6% in a COPD group.
Conclusion
The efficacy and safety of BPA for non-operable CTEPH with COPD were equivalent to those of patients without COPD. Oxygenation and FEV1.0% also improved in COPD patients. BPA might be considered even though patients comorbid COPD.

Abstract
BackgroundIn immunoglobulin G4-related kidney disease (IgG4-RKD), persistent renal insufficiency may be observed despite the good initial response to glucocorticoids[1, 2]. However, its long-term prognosis in relation to renal function as well as malignancy and mortality has not been well clarified.ObjectivesTo clarify the long-term renal prognosis, complications of malignancy, mortality, and factors related to those outcomes in IgG4-RKD.MethodsWe retrospectively reviewed the medical records of patients with IgG4-RKD diagnosed by the expert members of the IgG4-RKD working group in the Japanese Society of Nephrology. We investigated clinical, radiological, and histopathological features at baseline and course of renal function, complications of malignancy, and mortality during the long-term observation periods (median 71 months) in 75 patients. Using collected data, we calculated the crude incidence rates (IR) of chronic kidney disease (CKD) status, malignancy, and death. Cox regression analyses were performed to assess CKD-related factors. Additionally, we calculated the standardized incidence ratio (SIR) of malignancy and standardized mortality ratio (SMR) using national Japan statistics.ResultsFifty-nine patients were male, and 16 were female (median age 70 years). At diagnosis, their median eGFR was 45.1 mL/min/1.73m2 (interquartile range [IQR] 28.6-69.9). Seventy-two patients (96%) were treated with prednisolone at a median initial dose of 30 (IQR 30-39) mg/day, leading to a reasonable initial improvement of renal function. The IR of CKD was 30.2/100 person-years, and 66.7% (50/75) of the patients showed CKD at the last visit. Age- and sex-adjusted Cox regression analyses indicated that lower eGFR (per 10 mL/min/1.73m2, hazard ratio [HR] 0.70, 95% confidence interval [CI] 0.61-0.80), pre-existing hypertension (HR 2.39, 95% CI 1.32-4.34), and wider areas with inflammation (>50% vs. <10%, HR 2.55, 95% CI 1.07-6.08) or fibrosis (>50% vs. <5%, HR 2.84, 95% CI 1.18-6.85) in the biopsied renal specimens at treatment initiation had a significant impact on the time to CKD. Eight patients (10.7%) died during follow-up due to malignancy, severe infection, cerebral hemorrhage, or myocardial infarction. The crude mortality rate was 1.76/100 person-years, and a SMR calculated according to national Japan statistics was 0.97 (95% CI 0.42-1.90). On the other hand, 15 patients were diagnosed as having malignancies during follow-up. The IR of malignancy was 3.71/100 person-years, and the SIR of malignancy was 1.80 (95% CI 1.03-2.93).ConclusionThis study suggests that pre-treated renal insufficiency and extensive renal inflammatory and fibrotic lesions are related to CKD under glucocorticoid therapy in IgG4-RKD. Similarly with the whole IgG4-related disease, IgG4-RKD may have an increased incidence of malignancy but a mortality rate equivalent to the age- and sex-matched Japanese population.References[1]Saeki T et al.

Abstract
Background:Clinical characteristics of nonradiographic axial spondyloarthritis (nr-ax-SpA) are highly variable across patients, and may potentially vary across patient populations, particularly due to differing distributions of human leukocyte antigens (HLA) and other genetic factors. The majority of nr-ax-SpA studies have been conducted in Europe, the United States, and small studies are reported from Asia [1].Objectives:To delineate clinical characteristics of patients with nr-ax-SpA in Asian countries in comparison to other areas of the world.Methods:Utilizing the ASAS-COMOSPA data, an international cross-sectional observational study of SpA patients, we analyzed information on demographics, disease characteristics, comorbidities, and risk factors. Patients were classified by region: Asia (China, Japan, Singapore, South Korea, and Taiwan), and non-Asian countries (Europe, Americas, and Africa); patient characteristics, including diagnosis and treatment, were compared.Results:Among 3984 SpA patients included in the study, 1094 were from centers in Asian countries, and 2890 from other regions. 112/780 (14.4%) of axial SpA patients in Asian countries were nr-ax-SpA, substantially less than in other countries (486/1997, 24.3%). Nr-ax-SpA patients in Asian countries compared to nr-ax-SpA in other countries were more likely male (75.9 vs 47.1%), have onset (22.8 vs 27.8 years) and diagnosis (27.2 vs 34.5 years) at younger age, and experience less diagnostic delay (1.88 vs 2.92 years) (Table 1). Nr-ax-SpA patients in Asian countries have higher prevalence of positive HLA-B27 (90.6% vs 61.9%) and fewer peripheral signs such as arthritis, enthesitis, or dactylitis (53.6% vs 66.3%) but have similar rate of extra-articular manifestations (psoriasis, IBD, or uveitis) and co-morbidities. Disease activity, functional impairment, and inflammation on MRI were less in nr-ax-SpA patients in Asian countries. NSAIDs response was higher and use of methotrexate and b-DMARDs were lower among nr-ax-SpA in Asian countries.Conclusion:Among axial SpA patients, substantially lower frequency of nr-ax-SpA was observed in Asian countries compared to other regions of the world. Nr-ax-SpA patients in Asian countries were predominantly male, and had younger disease onset with higher HLA-B27 positivity rate and less peripheral signs, and better response to NSAIDs. These results offer an opportunity to improve both early diagnosis and treatment of nr-ax-SpA patients in Asian countries.Table 1.Characteristics of nonradiographic axial SpA in Asia versus non-Asian regionsVariablesAsianon-Asian regionsp valueN112486Age at disease diagnosis, yrs27.2 [21.1, 39.6]34.5 [27.7, 41.7]<0.001Diagnostic delay, yrs1.88 [0.27, 5.56]2.92 [0.59, 9.58]0.011Male (%)85 (75.9)229 (47.1)<0.001Sacroiliitis on MRI among tested (%)49 (67.1)341 (82.2)0.005HLA B27 positivity among measured (%)96 (90.6)273 (61.9)<0.001Inflammatory Back Pain (%)107 (95.5)478 (98.4)0.076Arthritis, enthesitis, or dactylitis (%)60 (53.6)322 (66.3)0.016Psoriasis (%)12 (10.7)82 (16.9)0.142Uveitis (%)20 (17.9)81 (16.7)0.870Inflammatory bowel disease (%)5 (4.5)27 (5.6)0.817Elevated CRP (%)37 (33.0)213 (43.8)0.048Physician global assessment (0-10)2.0 [1.0, 5.0]2.0 [1.0, 4.0]0.741Patient global assessment (0-10)3.0 [1.0, 6.0]4.0 [2.0, 6.0]0.012ASDAS-CRP1.40 [0.95, 2.08]1.97 [1.21, 2.78]<0.001BASFI0.8 [0.05, 2.65]2.9 [0.8, 5.6]<0.001Good response to NSAIDs (%)80 (71.4)272 (56.0)0.004Methotrexate use (%)18 (16.1)134 (27.6)0.016Biological DMARDs use (%)27 (24.1)191 (39.3)0.004References:[1]López-Medina C, Ramiro S, van der Heijde D, et al.

Abstract
OBJECTIVE To examine the association between the severity of oral frailty (OF), which is one of the comprehensive oral functions evaluated, and dietary variety in community-dwelling older persons. DESIGN Cross-sectional study. SETTING Community-based. PARTICIPANTS A total of 769 community-dwelling older persons aged 65 and over. INTERVENTIONS We examined basic demographic information, functional status, cognitive status, depressive symptoms, medical history, and oral functions of the participants. MEASUREMENTS OF was defined by 1-2 and 3 or more of 6 items of oral function evaluation in the pre-oral frailty and oral frailty groups, respectively. Dietary variety was assessed using the dietary variety score (DVS). The participants were categorized into 3 groups for evaluation: those with a low score (0-2), medium score (3-5), and high score (≥6). Ordinal logistic regression analysis was performed to examine the association between OF and DVS. RESULTS The rate of OF in the participants was 21.6%, and its severity was significantly associated with DVS after adjusting for potential confounders (Pre-OF; adjusted odds ratio [OR] = 1.687, 95% confidence interval [CI] = 1.219-2.335, OF; adjusted OR = 2.857, 95% CI = 1.489-5.484). CONCLUSION The severity of OF was significantly associated with DVS in community-dwelling older persons. This suggests that DVS may be useful in understanding the effects of OF on the nutritional status. Further longitudinal studies are needed to elucidate the association between OF and DVS.

Abstract
Background: There is limited evidence regarding associations between fruit and vegetable consumption and incident frailty risk among older people. Objectives: The objective of this study was to conduct a systematic review and meta-analysis regarding the association between fruit and vegetable consumption and incident frailty risk among older adults. Methods: A systematic search of the literature was conducted according to the PRISMA guidelines using PubMed in January 2021 for studies that prospectively examined risk of incident frailty in relation to fruit and vegetable consumption in older adults aged 60 and older. Methodological quality and heterogeneity were assessed. Odds ratios (OR) were pooled using random-effects or fixed-effects meta-analysis, depending on the presence of heterogeneity. Results: Among three studies included in this review, data of four cohorts were provided by two studies and used in meta-analysis. The highest fruit and vegetable consumption was significantly associated with lower risk of incident frailty compared with the lowest consumption (pooled OR=0.38, 95%CI=0.24-0.59, p=<0.001). Conclusions: This study provided the pooled evidence that high fruit and vegetable consumption may be beneficial for preventing the development of frailty in older adults. Increasing fruit and vegetable consumption can be a relevant strategy to prevent frailty.

Abstract
Abstract
Background
It has been reported that balloon pulmonary angioplasty (BPA) could dramatically improve hemodynamics in patients with chronic thromboembolic pulmonary hypertension (CTEPH). However, some patients have shown poor response in oxygenation and lung function even after BPA. The aim of our study was to evaluate the efficacy of BPA using clinical indicators and to investigate lung function and residual hypoxemia.
Method
Consecutive 103 patients who underwent BPA from September 2011 to August 2018 were enrolled. We evaluated hemodynamics with right heart catheterization, respiratory function test, arterial blood gas examination, and exercise capacity with 6 minute-walk-distance (6MWD).
Result
At the median 12-month follow-up after the final BPA session, following examination findings were significantly improved. Mean pulmonary artery pressure (39.0±8.2mmHg, 23.2±8.4mmHg, p<0.001), Pulmonary vascular resistance (782±378 dynes / sec / cm-5, 331±187 dynes / sec / cm-5, p<0.001), 6 MWD (310±94 m, 363±119 m, p<0.001), PaO2 (63.1±15.8 mmHg, 68.5±13.6 mmHg, p=0.044),%VC (88.5±17.1, 91±16.3, p=0.036). However, the following examination findings did not improve after BPA. Oxygen desaturation during 6MWD test (−11.9±6.3, 12±7.9, p=0.65), %DLCO (64.2 17.1, 61.3 16.8, p=0.147).
Conclusion
BPA could dramatically improve hemodynamics and exercise tolerance. However, arterial oxygenation was not normalized after BPA. Moreover, oxygen desaturation in exercise, and %DLCO were almost unchanged. These observations might suggest the remaining arteriopathy in capillary level of pulmonary artery, but further research is needed.

Abstract
Abstract
Background
This study evaluated whether caffeine abstention is required before fractional flow reserve (FFR) measurement by intravenous adenosine triphosphate (ATP) administration in Japanese patients.
Methods and results
This study was a subanalysis of a previously published study and a total of 208 intermediate lesions that underwent FFR measurements were enrolled for this analysis. Hyperemia was induced by continuous intravenous ATP infusion at 150μg/kg/min (IVATP150) and 210μg/kg/min (IVATP210), and by intracoronary administration of nicorandil 2mg (ICNIC2mg) as a reference standard. The degree of change in the FFR value both after IVATP150 and after IVATP210, as compared with the FFR value after ICNIC2mg was similar between the caffeine and non-caffeine groups (−0.04±0.05 vs. −0.04±0.07, and 0.00±0.02 vs. 0.01±0.02, respectively). In patients who consumed caffeine before the FFR measurement, the degree of FFR change was independent of the time interval (<12 hours, 12–24 hours, and 24–48 hours) between caffeine intake and catheterization both after IVATP150 and ICNIC2mg and after IVATP210 and ICNIC2mg.
Conclusion
When compared with the FFR value after ICNIC2mg, the degree of change in the FFR value both after IVATP150 and after IVATP210 remained similar regardless of caffeine intake. Strict caffeine abstention before intravenous ATP-induced FFR measurement may not be required in clinical practice.

Abstract
Abstract
Background
It has been previously reported that poor subpleural perfusion (PSP) in dual-energy computed tomography (DE-CT) might suggest the microvasculopathy in patients with chronic thromboembolic pulmonary hypertension (CTEPH). However, it remains unclear whether pathological findings of microvasculopathy in CTEPH and pulmonary arterial hypertension (PAH) are equivalent. The aim is to evaluate the microvasculopathy in CTEPH and PAH by using clinical parameters and DE-CT.
Methods
We retrospectively reviewed PSP (defined as subpleural spaces either not or minimally perfused in all segments) of consecutive treatment-naïve 89 CTEPH patients and 20 PAH patients who underwent DECT from Feb. 2015 to Dec. 2019.
We also evaluated hemodynamic parameters and DE-CT parameters including quantitative evaluation of pulmonary blood volume (PBV) which was calculated as the average of entire lung iodine density.
Results
PSP was observed in 49.4% of patients in CTEPH group versus 5.0% in PAH group (p<0.01).
There were no significant differences in hemodynamics and lung PBV between CTEPH group and PAH group (mean pulmonary arterial pressure; 36.4±10.4mmHg vs 38.3±8.5mmHg p=0.464, pulmonary vascular resistance; 700±388dyne*sec/cm5 vs 805±440 dyne*sec/cm5 p=0.288, lung PBV; 24.9±6.4 Hounsfield Unit vs 22.0±6.6 Hounsfield Unit p=0.06, respectively), however diffusing capacity for carbon monoxide (%DLCO/VA) was significantly lower (69.5±16.8% vs 45.7±23.7% p<0.01) in PAH group.
Conclusion
PSP in DE-CT, which was observed more frequently in patients with CTEPH, might suggest the different mechanism of microvasculopathy from PAH in patients with CTEPH. Microvasculopathy in CTEPH would be diffuse very distal thrombosis. DE-CT is effective modality to detect microvasculopathy of diffuse distal thrombosis in patients with CTEPH.

Abstract
Abstract
Background
Metabolic syndrome is a cluster of conditions including obesity, insulin resistance, hypertension, and abnormal cholesterol, which increases the cardiovascular risk. Metabolic syndrome or obesity has been reported to provide systemic inflammation and oxidative stress. Increased epicardial fat volume is a manifestation of obesity or metabolic syndrome. Those systemic and local conditions related to obesity or metabolic syndrome have been linking to the risk of atrial fibrillation (AF). The underlying mechanisms of obesity linking epicardial fat to AF progression have not been fully examined.
Purpose
To investigate the impact of obesity linked to epicardial fat on electrophysiologic and anatomical AF substrates.
Methods
Twenty dogs aged 3 years were divided into four groups (n=5 per each): normal diet for over 20 weeks (control group [median body weight: 12.0 kg]), rapid atrial pacing (RAP) for last 4–15 (median 8) weeks during a normal diet for the same period (RAP group [10.5 kg]), high-fat diet (HFD) maintained for over 20 weeks without RAP (MetS group [16.0 kg]), and RAP for last 4–12 (median 6) weeks during HFD maintained for 24 weeks (MetS-RAP group [17.0 kg]), respectively. Activation/voltage maps of the atria during sinus rhythm were created with Ensite NavX mapping system. The effective refractory period (ERP) at 5 left atrial (LA) and pulmonary vein (PV) sites (LA appendage [LAA], LA body, right and left superior PVs, and inferior PV), and AF inducibility by burst LAA pacing were determined. At study completion, hearts were excised for histopathological and gene expression analyses.
Results
The LA pressure was more significantly increased in MetS than the MetS-RAP, RAP, and control groups (22.5 [17–28.8] mmHg vs. 14.0 [10.5–16.3] mmHg, 10.5 [7.4–17.2] mmHg and 10.7 [9.6–13.5] mmHg, respectively, P<0.05). The LA/PV ERP at a basic cycle length of 400 ms was shorter in the MetS-RAP and RAP than MetS and control groups (118±39 ms and 122±44 ms vs. 136±18 ms and 155±39 ms, respectively, P<0.05). Short duration AF was more induced in the MetS and MetS-RAP than RAP and control groups (3 [0–5.5] sec and 2 [0.5–3.5] sec vs. 0 [0–4.5] sec and 0 [0–0] sec, P<0.05). Histological examinations showed the fatty infiltration extending from epicardial fat increased more in the Mets and Mets-RAP than RAP and control groups (Figure). The Fibronectin 1 and collagen I/III mRNA levels increased more in the MetS-RAP and AF than MetS and control groups.
Conclusions
AF vulnerability was associated with increased LA pressures and fibrofatty infiltration from epicardial fat in the MetS group, and with fibrofatty infiltration from epicardial fat with subtle fibrosis in the MetS-RAP group. This suggested that fibrofatty infiltration and epicardial fat plays an important role in AF pathogenesis in obese patients.

Abstract
Abstract
Background
The existence of microvasculopathy in chronic thromboembolic pulmonary hypertension (CTEPH) had been suggested. However, the impact of microvasculopathy for pathophysiology had been unknown. Recently dual-energy computed tomography (DECT) can produce a sensitive iodine distribution map in lung fields to quantify lung perfusion, which may indicate the existence of microvasculopathy according to poor subpleural perfusion.
This study aimed to examine the therapeutic efficacy of interventional treatment (pulmonary endarterectomy or/and balloon pulmonary angioplasty) in CTEPH with microvasculopathy.
Methods
We retrospectively reviewed poor subpleural perfusion (defined as subpleural spaces either not or minimally perfused in all segments) and hemodynamics of 70 consecutive CTEPH patients who underwent DECT before and after interventional therapy from January 2014 to January 2020.
Patients were divided according to poor subpleural perfusion in DECT images before treatment: a microvasculopathy group (MV group, n=37) or a non-microvasculopathy group (Non-MV group, n=33).
We evaluated clinical parameters as WHO functional class (WHO-Fc), 6-min walk distance, respiratory function test, cardiopulmonary exercise test, hemodynamic parameters, and DECT parameters at baseline and after the treatments. DECT parameters as quantitative evaluation of pulmonary blood volume (PBV) calculated as the average of entire lung iodine density.
Results
After interventional treatments, WHO-Fc improved in 33 patients in MV group, and 27 patients in Non-MV group (p=0.50).
In MV group, baseline mean pulmonary arterial pressure (mPAP), pulmonary vascular resistance (PVR) and VE/VCO2 slope were higher (38.3±9.3 vs. 33.2±10.8 mmHg p=0.04, 818±394 vs. 539±289 dyne*sec/cm5 p<0.01 and 43.7±11.3 vs. 35.2±6.9 p<0.01, respectively) and PBV were lower (43.7±11.3 vs. 35.2±6.9 Hounsfield Unit p<0.01) After the treatments, mPAP, PVR, VE/VCO2 slope and PBV showed almost equivalent between the groups (19.5±4.1 vs. 20.6±5.1 mmHg p=0.35, 272±111 vs 251±109 dyne*sec/cm5 p=0.42, 29.2±6.3 vs. 26.0±6.1 p=0.06 and 27.1±6.6 vs. 29.6±6.6 Hounsfield Unit p=0.13).
Diffusing capacity for carbon monoxide (%DLCO/VA) did not improve after treatment in both groups (MV group: 59.5±13.1 to 58.8±11.9% p=0.43. Non-MV group: 77.8±13.4% to 70.5±10.8% P<0.01).
Conclusion
Hemodynamics, pulmonary perfusion, exercise capacities significantly improved after the treatments in spite of the existence or absence of microvasculopathy. However, DLCO which might indicate the existence of microvasculopathy did not improve. Interventional treatments could not improve microvasculopathy because of their limit of accessibilities.

Abstract
Abstract
Background
The management of non-operable chronic thromboembolic pulmonary hypertension (CTEPH) has recently evolved with the availability of balloon pulmonary angioplasty (BPA) and pulmonary vasodilators. We launched BPA program since 2011. The aim was to analyze survival and treatment efficacy in the modern management era.
Method and result
We retrospectively reviewed data from 143 consecutive CTEPH patients diagnosed in our university from January 2011 (i.e. after the availability of BPA) to December 2019. Forty-one patients underwent PEA, in these 25 patients underwent additional BPA (Hybrid group) and other patients were treated with only PEA (PEA group). Ninety patients underwent BPA (BPA group), remaining 12 patients had not undergone any interventional treatments. The 1- and 5-year survival rates of operated patients (n=41) were 97.4% and 90.0%, compared to96.9% and 86.9% in not-operated patients (n=102), respectively (p=0.579) (Figure). There was no death in Hybrid group. Percent decrease of pulmonary vascular resistance in PEA group, Hybrid group, BPA group were −75.4±9.9%, −74.3±11.8%, −56.3±22.2%, respectively (p<0.01, one-way ANOVA). Absolute decrease of mean pulmonary artery pressure in each groups were −20.3±9.5mmHg, −24.5±8.8mmHg, −16.4±9.2mmHg, respectively (p<0.01, one-way ANOVA).
Conclusion
There was no longer significant difference of long-term survival between operated and not-operated CTEPH. Moreover, Hybrid approach might have the potential to lead notable improvement in the prognosis of CTEPH. BPA and PEA would be mutually complementary therapies in the modern management era.

Abstract
Abstract
Background
The 6th World Symposium on Pulmonary Hypertension suggested major revision about definition of pulmonary hypertension (PH) as mean pulmonary artery pressure (mPAP) >20 mmHg. The definitions of two subsets of PH due to left heart disease (PH-LHD) also revised. The aim of this study was to investigate clinical characteristics and outcomes of subsets of PH-LHD defined by new criteria.
Methods
We analyzed 701 patients admitted for symptomatic heart failure (NYHA ≥2) and underwent right heart catheterization at compensated stage between 2007 and 2016. These patients were divided into 4 groups as follows: (i) Isolated post-capillary PH (Ipc-PH); mPAP >20 mmHg and pulmonary artery wedge pressure (PAWP) >15 mmHg and pulmonary vascular resistance (PVR) <3 WU, (ii) Combined pre- and post-capillary PH (Cpc-PH); mPAP >20 mmHg and PAWP >15 mmHg and PVR ≥3 WU, (iii) pre-capillary PH; mPAP >20 mmHg and PAWP ≤15 mmHg, (iv) no PH; mPAP ≤20 mmHg. Kaplan-Meier curves were applied to investigate whether each groups predict heart failure (HF) death or HF readmission.
Results
The study patients were divided into Ipc-PH (n=268), Cpc-PH (n=54), Pre-capillary PH (n=112), and no PH (n=267). Cpc-PH was significantly associated with HF death or HF readmission as compared to other groups (Figure).
Conclusions
Cpc-PH defined by new criteria was significantly associated with poor long-term clinical outcomes, which suggests new criteria of two subsets of PH-LHD could be strict risk stratification for symptomatic heart failure.

Abstract
PURPOSE This study evaluated the efficacy and safety of nivolumab treatment beyond progressive disease (PD) in non-small cell lung cancer (NSCLC). PATIENTS/METHODS Medical records of consecutive patients with advanced NSCLC who received nivolumab between December 2015 and December 2018 were reviewed. Clinical outcomes of three groups of eligible patients who received nivolumab as a second-line treatment after PD were compared based on Response Evaluation Criteria in Solid Tumors v1.1. We conducted subgroup analyses in patients with and without new lesions at first PD. RESULTS Twenty-eight patients continued nivolumab treatment beyond PD (TBP). Post PD, 46 patients switched to other anti-cancer treatment (OAT), and 21 received no further anti-cancer treatment (NAT). There were no significant differences in overall survival (OS) or survival post progression (SPP) between TBP and OAT groups (OS: 15.6 vs. 13.4 months, P = .40, SPP: 12.2 vs. 9.3 months, P = .42). Subgroup analyses indicated that among patients without new lesions at first PD, SPP was longer in the TBP than in the OAT groups (12.6 vs. 9.3 months, P = .22, HR: 0.64; 95% CI 0.31‒1.31). The frequency of immune-related adverse events leading to discontinuation during nivolumab beyond PD was equivalent to that for pre-PD (10.7 vs. 12.6%). CONCLUSIONS No significant benefits were associated with continuation of nivolumab for advanced NSCLC patients. Continuation of nivolumab beyond PD could be a more useful option in patients without new lesions at first PD. Treatment-related toxicities require attention during nivolumab treatment not only before PD but also beyond PD.

Abstract
Objectives:To assess the clinical implications of ultrasonography (US) in monitoring disease activity and diagnosis of relapsing polychondritis (RP).Methods:Firstly, auricular (n=5) and nasal (n=1) chondritis of six patients with RP were assessed by US before and after treatments. The relationship between US findings and serum markers were evaluated. Moreover, the comparisons of US findings between the auricle of patients with RP (n=5), repeated trauma (n=5), cellulitis (n=2) and healthy subjects (n=5) were also assessed.Results:US finding before treatment showed low-echoic swollen auricular and nasal cartilage with increased power Doppler signals (PDS) in all cases of RP. US findings corresponded to biopsy findings. After treatment, the swollen ear and nose completely resolved. Then, US findings also showed dramatic reductions in swollen cartilage with the decrease in PDS. Although serum markers completely improved, US finding remained in 1 of 6 cases, and this case showed flare due to PSL tapering. Finally, RP could be differentiated from the damage of repeated trauma and cellulitis by the presence or absence of PDS and subperichondrial serous effusion.Conclusion:US of auricular and nasal cartilage in RP possibly facilitates evaluation of auricular lesions and monitoring of disease activity, especially when we consider the treatment response and the timing of drug tapering.Disclosure of Interests:None declared

Abstract
Background:Synovitis, acne, pustulosis, hyperostosis, osteitis (SAPHO) is a rare disease involving skin and skeleton, with a potentially complicated and severe course, optimal management of which seems to require a collaborative rheumatology and dermatology care. Diagnostic criteria for SAPHO remain preliminary and lack validation. There are no evidence-based treatment algorithms in SAPHO due to lack of clinical trials in this rare medical condition.Objectives:This study aimed to investigate the current practice in the diagnosis and treatment of SAPHO syndrome among the international rheumatology and dermatology communities.Methods:We conducted a survey among the members of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) combining international rheumatologists and dermatologists as well as members of the Japanese and Israeli Societies of Rheumatology.Results:A total of 78 physicians participated in the survey: rheumatologists (83%, n=65), dermatologists (11.5%, n=9), and orthopedics (3.8%, n=3). SAPHO was considered a subtype of spondylarthritis by 48.7% (n=38), a subtype of psoriatic arthritis by 19.2% (n=15), a separate entity by 25.6% (n=20), and a subtype of reactive arthritis by 6.4% (n=5). Palmoplantar pustulosis was the most prevalent cutaneous manifestation (n=44, 56.4%) and anterior chest pain - the most prevalent osteoarticular manifestation (n=66, 84.6%). The majority (84.6%, n=66) voted for the update of the present diagnostic criteria by Khan 1994. Magnetic resonance imaging was considered the preferred imaging modality for the diagnosis of SAPHO by 41% (n=32). Conduction of bone biopsy for diagnosis of non-infectious osteitis was supported only by 10.3% (n=8). Patient-reported outcomes were considered the most appropriate measure for the assessment of disease activity by 47.4% (n=37). The treatment approach was overall similar among the rheumatology and dermatology communities, including non-steroidal anti-inflammatory drugs, bisphosphonates, conventional disease-modifying anti-inflammatory drugs, and biologics (Table 1).Table 1.Preferences in the treatment choice of SAPHOTreatment% of respondersNSAIDs76.6%Glucocorticoids32.5%Conventional DMARDs57.1%Bisphosphonates48.1%Anti-TNF biologic therapy75.3%Other biologic therapy20.8%Antibiotic14.3%Tonsillectomy5.1%Isotretinoin5.2%Topical therapy10.4%Intra-articular steroid injection7.8%Legend: NSAIDs – non-steroidal anti-inflammatory drugs; DMARDs – disease modifying anti-rheumatic drugsConclusion:Our study underlines the controversy on diagnosis and treatment of SAPHO syndrome among specialists in rheumatology and dermatology and emphasizes an unmet need for update and validation of diagnostic criteria and treatment approach.Acknowledgments:GRAPPA, Japanese Society of Rheumatology, Israeli Society of RheumatologyDisclosure of Interests:Victoria Furer: None declared, Mitsumasa Kishimoto: None declared, Shigeyoshi Tsuji Grant/research support from: Eli Lilly, Speakers bureau: AbbVie, Asahi Kasei, Chugai, Daiichi Sankyo, Eli Lilly, Eisai, Mitsubishi Tanabe, Celgene, and Novartis Pharma K.K., Yoshinori Taniguchi: None declared, Yoko Ishihara: None declared, Tetsuya Tomita Consultant of: Eli Lilly and Company, Ori Elkayam Speakers bureau: AbbVie, BMS, Pfizer, Roche, Sanofi-Aventis, Novartis, Jansen

Abstract
Background:The 2019 ACR/EULAR classification criteria for IgG4-RD have recently been published1). In the criteria, patients with an inclusion criteria score of >20 without exclusion criteria are classified as having IgG4-RD.Objectives:To validate the 2019 ACR/EULAR classification criteria for IgG4-RD in a Japanese kidney disease cohort.Methods:The study involved Japanese patients diagnosed as having kidney disease between April 2012 and May 2019, for whom sufficient clinical information and data on serum IgG4 values and/or immunohistological staining for IgG4 in renal biopsy samples were known. These patients were classified as having IgG4-RKD or non-IgG4-RKD (mimickers) based on the 2019 ACR/EULAR classification criteria for IgG4-RD, and the results were evaluated by expert opinion.Results:Among 105 included patients, the expert panel diagnosed 55 as having true IgG4-RKD and 50 as mimickers. The final diagnoses among the mimickers were vasculitis (n=11), idiopathic tubulointerstitial nephritis (TIN) (n=5), drug-induced TIN (n=5), Sjögren’s syndrome (n=4) and others. Among the 55 true IgG4-RKD patients, 4 had exclusion criteria, and 50 of the remaining 51 had an inclusion criteria score of ≥20 points (sensitivity 90.9%). On the other hand, 49 of the 50 mimickers were classified as having non-IgG4-RKD (specificity 98.0%) (Table 1).Table 1.General characteristics and prevalence of individual items of true IgG4-RKD and non-IgG4-RKD (mimicker)IgG4-RKD(true IgG4-RKD)(n=55)Non-IgG4-RKD(mimicker)(n=50)PAge at diagnosis,mean ±SD (years)69.9 ± 9.456.7 ± 17.4<0.001Male (%)76.4440.001Elevated serum IgG454/55 (98.2%)18/50 (36.0%)<0.001Serum IgG4 (mg/dl), mean±SD1028 ± 796226 ± 261<0.001Dense IgG4+Plasma cells (>10/hpf) in the kidney biopsy48/51 (94.1%)13/40 (32.5%)<0.001Storiform fibrosis in the kidney biopsy28/51 (54.9%)3/50 (6%)<0.001Hypocomplementemia39/55 (70.1%)7/42 (16.7%)<0.001Renal pelvis thickening/soft tissue5/55 (9%)1/50 (2%)0.20Bilateral renal cortex low-density areas29/55 (52.7%)7/50 (14.0%)<0.001Exclusion criteria present4/55 (7.3%)22/50 (44%)<0.001Total inclusion criteria points >20 without exclusion criteria50/55 (90.9%)1/50 (2%)<0.001Conclusion:The 2019 ACR/EULAR classification criteria for IgG4-RD showed good agreement with expert classification in this Japanese kidney disease cohort.References:[1] Wallace ZS, et al.

Abstract
Background:Adult-onset Still’s disease (AOSD), a systemic inflammatory disorder, is characterized by high fever, evanescent rash, arthritis, and hyperferritinaemia. AOSD is also reported to be associated with other skin lesions, including persistent pruritic papules and plaques.Objectives:This study aimed to assess the significance of dyskeratotic skin lesions in Japanese AOSD patients.Methods:We retrospectively assessed the histology of persistent pruritic skin lesions and evanescent rashes and the relationship between dyskeratotic cells, serum markers, and outcomes in 20 Japanese AOSD patients, comparing AOSD histology with that of dermatomyositis (DM), drug eruptions, and graft-versus-host disease (GVHD).Results:Persistent pruritic lesions were characterized by scattered single keratinocytes with an apoptotic appearance confined to the upper layer of the epidermis and horny layer without inflammatory infiltrate. In contrast to AOSD, the histology of DM, drug eruption, and GVHD demonstrated dyskeratotic cells in all layers of the epidermis with inflammatory infiltrate. AOSD with evanescent rash showed no dyskeratotic cells. The dyskeratotic cells in pruritic AOSD lesions stained positive for ssDNA and terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling, indicating apoptosis. Serum IL-18 was significantly higher in AOSD patients with dyskeratotic cells than those without, and generally required higher doses of glucocorticoids, immunosuppressants, and biologic agents. Two of ten AOSD patients with dyskeratotic cells died from haemophagocytic lymphohistiocytosis.Conclusion:Persistent pruritic AOSD skin lesions are characterized by dyskeratotic cells with apoptotic features, involving the upper layers of the epidermis. There may be a link to elevated IL-18. This dyskeratosis may be a negative prognostic indicator.Disclosure of Interests:None declared

Abstract
UNLABELLED We compared the bone strength measured via quantitative computed tomography-based finite element method (QCT/FEM) between healthy adults with and without ossification of the posterior longitudinal ligament (OPLL). No statistically significant difference was observed in the bone strength between healthy adults with and without OPLL. Hyperostosis of the posterior longitudinal ligament in OPLL may not be associated with the systemic bone strength. INTRODUCTION Although patients with OPLL have been reportedly associated with increased level of bone mineral density (BMD) using dual-energy X-ray absorptiometry (DXA), little is known about the bone strength in OPLL subjects. The aim of this study is to investigate the bone strength measured via QCT/FEM in healthy subjects with OPLL using the medical check-up data, including whole-body CT scans. METHODS We examined 796 participants (529 men and 267 women) who underwent CT scans in a single health center between January 2008 and May 2009. We identified OPLL in whole spine and divided the subjects into two groups: non-OPLL and OPLL groups. We calculated the predicted bone strength (PBS) of the proximal femur using QCT/FEM and examined the bone mineral status of the calcaneus using quantitative ultrasound (QUS). We compared the PBS and the QUS parameters between the non-OPLL and OPLL groups. RESULTS Seventy-four subjects (9.3%; 57 men and 17 women) were diagnosed with OPLL in the whole spine. The OPLL group was significantly older than the non-OPLL group. No statistically significant difference was observed in the PBS and the QUS parameters between the non-OPLL and OPLL groups in both sexes. Furthermore, no statistically significant difference was noted in the PBS and the QUS parameters between two groups in age- and gender-matched analysis. CONCLUSIONS Our results suggest that hyperostosis of the posterior longitudinal ligament in OPLL may not be associated with bone strength and bone mineral status at the extremities.

Abstract
We examined the effect of isomaltodextrin (IMD), a soluble dietary fiber, on production of putrefactive products by intestinal bacteria using a tyrosine load test to measure phenol production in IMD-treated rats. We observed a significant increase in phenol and p-cresol concentrations in rats administered with only tyrosine, but not for rats co-administered tyrosine and IMD. To elucidate the mechanism of this effect, we analyzed the intestinal microbiota in each group and found that although IMD had no direct effect on the proportion of bacteria known to produce phenols, it did alter the balance of intestinal microbiota. The results suggested that changes in the intestinal microbiota composition reduced the metabolic capacity for tyrosine and in turn suppressed production of phenol or p-cresol, putrefactive products in the intestine.

Abstract
:The purpose of this study was to identify the anti-inflammatory activity and mechanism of isomaltodextrin (IMD) in a C57BL/6NCrl mouse model with lipopolysaccharide (LPS)-induced systemic low-grade chronic inflammation and the effect on inflammation-induced potential risk of metabolic disorders. Pre-treatment of IMD decreased the production of pro-inflammatory mediators, TNF-α and MCP-1, and stimulated the production of the anti-inflammatory mediator, adiponectin by increasing the protein expression of peroxisome proliferator-activated receptor gamma (PPAR-γ) in the white adipose tissues. IMD administration reduced plasma concentrations of endotoxin, decreased macrophage infiltration into adipocytes, and increased expression of mucin 2, mucin 4, and the tight junction protein claudin 4. These results suggest that IMD administration exerted an anti-inflammatory effect on mice with LPS-induced inflammation, potentially by decreasing circulating endotoxin, suppressing pro-inflammatory mediators and macrophage infiltration, or by improving mucus or tight junction integrity. IMD exerted protein expression of insulin receptor subset-1 (IRS-1). IMD alleviated the disturbance of gut microflora in LPS-treated mice, as the number of B. bifidum, L. casei, and B. fragilis increased, and E. coli and C. difficile decreased, when compared to LPS-treated mice. The analysis of short chain fatty acids (SCFAs) further supported that the concentrations of acetic and butyric acids were positively correlated with IMD, as well as the number of beneficial bacteria. This study provides evidence that IMD possesses anti-inflammatory properties and exerts beneficial functions to prevent systemic low-grade chronic inflammation and reduces the risk of developing insulin resistance and associated metabolic diseases.

Abstract
The aim of this study was to evaluate the potential effects of isomaltodextrin (IMD), a dietary saccharide polymer derived from enzymatically produced from starch, on the ability to alter immune response (IR) bias to hen egg ovalbumin (Ova) induced allergic inflammation in mice. Groups of Balb/c mice were pre-treated with various doses of IMD in drinking water (1.0, 2.5, and 5.0% w/v) for 6 weeks and subsequently sensitized to the Ova together with continuous administration of IMD. To evaluate changes in immune response bias, immunoglobulin isotype-associated antibody activity, concentrations of type 1 and 2 cytokines and the percentage of T-regulatory cells (T-regs) in blood were measured. Clinical signs of allergy were assessed after oral challenge with Ova. Treatment with IMD did not significantly alter the frequency of clinical signs, however there was a trend in the overall reduction of clinical signs. Effect on IR bias was observed in the treatment groups as reflected by reduction in a type 1-biased phenotype as evident by decrease in isotype-specific IgE, IgG and increase in IL-12 cytokine production and a high proportion of T-regs. This study revealed that IMD could be a useful prophylactic candidate for alteration of allergic IR bias in mice and an immune-stimulator for reducing egg induced allergic reactions.

Abstract
Abstract
Background
The existence of microvasculopathy in patients with chronic thromboembolic pulmonary hypertension (CTEPH) had been suggested. However, the impact of microvasculopathy for pathophysiology had been unknown. Recently dual-energy CT (DECT) can produce a sensitive iodine distribution map as blood perfusion in lung fields to quantify lung perfusion, also can suggest the existence of microvasculopathy according to poor subpleural perfusion which was published previously.
Methods
We retrospectively reviewed poor subpleural perfusion (defined as subpleural spaces either not or minimally perfused in all segments) and hemodynamics of 83 treatment-naïve CTEPH patients who underwent DECT from February 2014 to Jan 2019. Patients were divided according to poor subpleural perfusion: a microvasculopathy group (n=44) or a non-microvasculopathy group (n=39).
We assessed cardiopulmonary exercise test, right heart catheterization and DECT parameters as quantitative evaluation of pulmonary blood volume (PBV). PBV was calculated as the average of entire lung iodine density.
Results
PBV value in non-microvasculopathy group showed significant inverse correlation with pulmonary vascular resistance (PVR) (y = 14236 x-1.028 r=−0.530, p<0.01).
PBV, SvO2, and %DLCO/VA were significantly lower (22.0 vs. 26.4, p<0.01, 61.3 vs. 66.0, p<0.01, and 59.2 vs 75.9 p<0.01), and systolic pulmonary arterial pressure, PVR, VE/VCO2 slope, BNP were higher (69.3 vs 60.6 p=0.04, 834 vs 586 p<0.01, 45.5 vs. 37.8, p=0.02, and 440 vs 122 p=0.04) in microvasculopathy group, while the other parameters were similar between the two groups.
Multivariate analysis revealed that %DLCO/VA was the only predictor of microvasculopathy (OR,0.895 [95% CI, 0.835 - 0.960]; P<0.01).
Conclusion
Pulmonary blood flow of patients in non-micorvasculopathy group showed inverse correlation with PVR. DECT was effective to assess the microvasculopathy in CTEPH. In our experience, less than 60% of non-operable CTEPH patients have microvasculopathy.

Abstract
Abstract
Background
Chronic thromboembolic disease (CTED) is characterised by thromboembolic stenosis and obstruction of pulmonary arteries without pulmonary hypertension. The treatment approach for symptomatic patients with CTED is still controversial. It has been reported the efficacy of surgical endarterectomy for patients with CTED, however that of balloon pulmonary angioplasty (BPA) for non-operable CTED has not been well established.
Method
We started aggressive BPA protocol for non-operable CTED patients who suffered from symptom with NYHA class II, III, and IV or limitation of exercise in spite of mean pulmonary artery pressure (mPAP) <25 mmHg since February 2014. We evaluated subjective symptoms, hemodynamic parameters by right heart catheter, and exercise capacity by cardiopulmonary exercise test at baseline and after the last BPA session.
Results
Twenty-three patients with CTED (68.7±10.5 years-old, 7 male) had undergone BPA. In these, 7 patients had received pulmonary vasodilators previously. After 2.9±1.3 sessions of BPA, Further improvement was observed in hemodynamics such as mPAP (21.6±2.3 to 17.1±2.6 mmHg, p<0.01), pulmonary vascular resistance (278±80 to 198±63 dyne/s/cm–5, p<0.01), which were accompanied with improved peak VO2 (14.6±4.4 to 17.4±4.2 ml/min/kg, p<0.01), VE/VCO2 slope (39.6±14.6 to 30.2±6.0, p=0.01), and functional class (I/II/III/IV; 0/10/12/1 to 9/12/2/0, p<0.01) (Table). All patients were tolerable, and no severe complication regarding to BPA.
Table 1 Variables Baseline After BPA (3 month) P value NYHA class (I / II / III / IV) 0 / 10 / 12 / 1 9 / 12 / 2 / 0 <0.01 Mean PAP (mmHg) 21.6±2.3 17.1±2.6 <0.01 PVR (dyne/sec/cm–5) 278±80 198±63 <0.01 6 MWD (m) 354±93 382±96 0.09 Peak VO2 (ml/min/kg) 14.6±4.4 17.4±4.2 <0.01
Conclusion
BPA may have the potential to achieve further improvement of exercise capacity and symptoms in CTED patients with acceptable risk, therefore BPA should be considered as a treatment option for symptomatic patients with non-operable CTED.

Abstract
Abstract
Background
Acute myocardial infarction (AMI) in the very elderly is associated with high morbidity and mortality. Because the majority of study population in clinical researches focusing on the very elderly with AMI were octogenarians, clinical evidences regarding AMI in nonagenarians are sparse. The aim of the present study was to compare in-hospital clinical outcomes of AMI between octogenarians and nonagenarians.
Methods
We included consecutive 415 very elderly (≥80 years) patients with AMI, and divided into the nonagenarian group (n=38) and the octogenarian group (n=377). Clinical characteristics and in-hospital outcomes were compared between the 2 groups. Furthermore, we used propensity-score matching to find the matched octogenarian group (n=38).
Results
Percutaneous coronary interventions (PCI) to the culprit of AMI were similarly performed between the nonagenarian (86.8%) and octogenarian (87.0%) groups The incidence of in-hospital death in the nonagenarian group (13.2%) was similar to that in the octogenarian group (14.6%) (P=0.811). The length of hospital stay was significantly shorter in the nonagenarian group (7.4±4.2 days) than that in the octogenarian group (15.4±19.4 days) (P<0.001). After using the propensity-score matching, the incidence of in-hospital death was less in the nonagenarian group (13.2%) than in the matched octogenarian group (21.1%) without reaching statistical significance (P=0.361). The length of hospitalization was significantly shorter in the nonagenarian group (7.4±4.2 days) than in the matched octogenarian group (17.8±37.0 days) (P=0.01).
Clinical outcomes Nonagenarian group (n=38) Octogenarian group (n=377) P value In-hospital death, n (%) 5 (13.2) 55 (14.6) 0.811 Length of hospital stay (days) 7.4±4.2 15.4±19.4 <0.001 Length of CCU stay (days) 3.3±2.5 4.7±5.1 0.109 LVEF (%) 48.2±9.2 50.8±13.7 0.152 Peak CPK (U/L) 1424.8±1580.8 1640.1±2394.4 0.912 CCU indicates Coronary care unit; LVEF, Left ventricular ejection fraction; CPK, Creatine kinase.
Flow-chart
Conclusions
The in-hospital mortality of nonagenarians with AMI was comparable to that of octogenarians with AMI. In-hospital outcomes in nonagenarians with AMI may be acceptable as long as acute medical management including PCI to the culprit of AMI is performed.

Abstract
OBJECTIVES This study evaluated associations of score-based and nutrient-derived dietary patterns with depressive symptoms in community-dwelling older Japanese. DESIGN Cross-sectional study. SETTING Community-based. PARTICIPANTS 982 community-dwelling adults aged 65 years or older. MEASUREMENTS Score-based pattern was assessed by using dietary variety score (DVS), which covers 10 food group items in Japanese meals. Nutrient-derived dietary patterns were identified by using reduced rank regression (RRR), with folate, vitamin C, magnesium, calcium, iron, and zinc intakes as response variables. Depressive symptoms were assessed with the Geriatric Depression Scale. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated for these dietary patterns in multivariate logistic regression analyses with potential confounders. The lowest consumption category was used as the reference group. RESULTS The prevalence of depressive symptoms was 13.5%. Higher DVS was associated with fewer depressive symptoms (OR=0.52, 95% CI=0.27-1.03 for the highest vs the lowest DVS; P for trend=0.031). The first RRR dietary pattern score was characterized by high intakes of fish, soybean products, potatoes, most vegetables, mushrooms, seaweeds, fruits, and green tea and a low intake of rice and was inversely associated with the prevalence of depressive symptoms (OR=0.53, 95% CI=0.30-0.92; P for trend=0.030). CONCLUSION Greater dietary variety and a dietary pattern characterized by high intakes of fish, soybean products, potatoes, most vegetables, mushrooms, seaweeds, fruit, and green tea and a low intake of rice were consistently associated with lower prevalence of depressive symptoms in community-dwelling older Japanese. Therefore, both patterns identified the components of dietary habits essential to depression prevention.
