Abstract
Background
Mutations in the LMNA gene encoding Lamin A/C, a major component of the nuclear lamina, cause laminopathies including dilated cardiomyopathy (DCM). DCM patients with LMNA mutations have particularly severe clinical courses such as heart transplantation and death due to heart failure. However, underlying mechanisms of LMNA-induced DCM remains elusive.
Methods and results
We identified LMNA Q353R mutation in a DCM family with severe heart failure. We generated Q353R heterozygous knock-in mice, which showed sarcomere dysplasia and perinatal lethality. Integrative single-cell analyses of the fetal murine hearts and patient-specific induced pluripotent stem cell-derived cardiomyocytes (iPSCMs) revealed that transcriptional regulation of cardiomyocyte maturation/development genes governed by TEAD1 was impaired in LMNA mutant cardiomyocytes. Protein array and immunostaining uncovered increased binding of TEAD1 to mutant Lamin A/C protein and abnormal localization of TEAD1 at the nuclear periphery. Furthermore, TT-10, a Hippo pathway inhibitor, rescued the dysregulation of cardiac developmental genes in LMNA mutant cardiomyocytes. Single-cell RNA-seq of cardiac tissues from DCM patients with the LMNA Q353R mutation confirmed the dysregulated expression of TEAD1 and its target genes. These results demonstrated abnormal interaction between TEAD1 and mutant Lamin A/C impairs structural maturation of cardiomyocytes and suggests that LMNA Q353R-related DCM can be treated through intervention in the Hippo pathway.
Conclusion
TEAD1 trapped by mutant Lamin A/C protein at the nuclear membrane perturbs transcriptional maturation in LMNA Q353R-related DCM.

Abstract
Abstract
Background
Walking speed (WS) is one of the key components of physical frailty associated with a prognosis in patients with heart failure (HF). However, the prognostic impact of changes in WS after discharge in patients with HF remains to be examined.
Purpose
The purpose of this study was to examined the association between the change in WS during 6 months after discharge and subsequent prognosis in older patients with HF.
Methods
This study was performed as a sub-analysis of the multicenter cohort study in Japan (FLAGSHIP). We analyzed patients hospitalized for HF aged ≥65 years whose WS was measured at discharge and after 6 months of discharge. Based on the patterns of WS at the two points, patients were divided into four groups (A: WS ≥0.98 m/s both at discharge and 6-month; B: ≥0.98 m/s at discharge, <0.98 m/s at 6-month; C: <0.98 m/s at discharge, ≥0.98 m/s at 6-month; D: <0.98 m/s both at discharge and 6-month). WS <0.98 m/s has been identified as a cut-off value predicting the prognosis of HF in the main analysis of the FLAGSHIP. Kruskal - Wallis test was used to compare among groups. Furthermore, Cox proportional hazards model was performed to evaluate the association between the WS subgroups and HF rehospitalization after 6-month of discharge. Additionally, adjustments were made for age and sex in model 1, and for age, sex, cognitive function (Mini-mental state examination, MMSE ≤23), past HF hospitalization, rehospitalization within 6 months after discharge, and variables with a p value <0.05 both at discharge and 6 months in univariate analysis in model 2.
Results
A total of 890 patients were included in this study (Group A: n=386, B: n=51, C: n=143, D: n=310). There was a significant difference in HF rehospitalization after 6-month of discharge among the four groups (Log-rank test, p=0.01, Figure 1). In the crude model, hazard ratio (HR) of group B compared with A was 2.26 [95% confidence interval: 1.19–4.27, p=0.013], HR of C was 1.00 [0.56–1.77, p=0.988], and HR of D was 1.66 [1.11–2.47, p=0.013]. In model 1, HR of B was 2.12 [1.11–4.07, p=0.023], HR of C was 0.99 [0.56–1.75, p=0.964], and HR of D was 1.56 [1.01–2.42, p=0.047]. In model 2, HR of B was 0.95 [0.45–1.97, p=0.897], HR of C was 0.67 [0.35–1.26, p=0.212], and HR of D was [0.25–0.80, p=0.007].
Conclusion
Although slow WS is associated with poor prognosis, the prognosis might be improved if WS increases by 6 months after discharge.

Abstract
OBJECTIVE The present study aimed to investigate the effects of a 4-week repeated oral intake of a quercetin-containing supplement on allergen-induced reactions and relative subjective symptoms in Japanese adults who complained of discomfort in the eyes and nose. SUBJECTS AND METHODS A randomized, placebo-controlled, double-blind parallel-group study was conducted on 66 subjects (22-78 years old) with allergic symptoms of pollinosis. The subjects were given the test product (200 mg quercetin) or the control product (vehicle) daily for 4 weeks. The Japanese Rhino-conjunctivitis Quality of Life Questionnaire (JRQLQ) scores and other tests were examined in each subject before and after starting the product intake. A new food-grade bioavailable formulation of quercetin, Quercetin phytosome®, was used. RESULTS At 1:4 weeks after the start of the supplement intake, several scores of JRQLQ, including allergic symptoms, such as eye itching, sneezing, nasal discharge, and sleep disorder, were significantly improved in the quercetin-containing supplement group compared with the placebo group. Furthermore, the quality of life of these subjects significantly improved based on the original questionnaire and visual analog scale. Minor notable adverse effects were noted throughout the study. CONCLUSIONS The results indicated that oral intake of quercetin-containing supplements might effectively reduce some allergy symptoms derived from pollinosis.

Abstract
BackgroundKnee joint disorder is one of the factors causing frailty in the elderly, which is associated with a decrease in walking speed.ObjectivesWe measured the walking speed of patients scheduled to undergo primary total knee arthroplasty (TKA) and examined factors correlated with walking speed.MethodsThe patients with knee disorders scheduled to undergo knee arthroplasty at our hospital between July 2020 and May 2021 were included. They were assessed for basic attributes, clinical assessment including Kness Society Score (KSS), degree of pain on walking by visual analogue scale (VAS), range of motion (ROM), and also leg skeletal muscle mass index (SMI; whole-body mode DXA), quadriceps strength by dynamometer with written consent (UMIN ID: 000040940). And Japanese Cardiovascular Health Study criteria for frailty, and sarcopenia by Asian Working Group for Sarcopenia 2019 criteria were evaluated.ResultsDemographic data of 83 patients (65 women, mean age 74.9 years) included in this study was shown in Table 1. The distribution in frailty is 36.2% and that in sarcopenia is 7.3%. Most of the patients with frailty with knee disorder did not suffer from sarcopenia. A multivariate analysis was conducted with walking speed as the objective variable and the dependent variables as age, gender, pain VAS on walking, KSS, leg SMI, quadriceps strength, and ROM. The results showed that age and ROM in flexion were significantly and independently associated with walking speed (P=0.01, 0.03). Gender, pain VAS on walking, KSS, leg SMI, quadriceps strength, and ROM in extension were not significantly associated with walking speed (P=0.92, 0.11, 0.11, 0.52, 0.85, 0.52).ConclusionAmong the patients with knee disorders immediately before arthroplasty, frailty was not caused by sarcopenia. Age was found to be the most correlated factor with walking speed, and walking speed became slower with age. In addition, poor flexion angle was also the factor for delayed walking speed, but it did not correlate with lower limb skeletal muscle mass or quadriceps strength. In this study pain on walking was not significant factor for walking speed, because it was observed in most of all cases.FactorGroup disease (n)osteoarthritis78 (94%) rheumatoid arthritis5 (6.0%)body mass index (kg/m2) 25.54 (4.11)pain VAS on walking 37.08 (26.35)total Knee Society Score 77.66 (27.85)range of motion (degree)flexion119.46 (12.88) extension-9.58 (6.59)quadriceps power (N) 122.00 [53.00, 350.00]waling speed (m/sec) 0.95 (0.33)grip power (kg) 20.24 (6.97)skeletal muscle mass index (kg/m2)appendicular6.50 [4.92, 9.85] lower limb5.06 [3.76, 7.56]Frailty (n)none10 (12.5%)Pre-frail41 (51.2%) frail29 (36.2%)Sarcopenia (n)none76 (92.7%)sarcopenia4 (4.9%) severe sarcopenia2 (2.4%)mean (standard deviation); median [min max]Disclosure of InterestsNone declared

Abstract
BackgroundDifficult-to-treat rheumatoid arthritis (D2T RA) is defined as RA in which disease activity is uncontrolled despite the use of two or more biologics or Janus kinase inhibitors (JAKi) with different mechanisms of action (MOA).ObjectivesTo explore the optimal treatment strategy for D2T RA, we evaluated the drug retention, efficacy, and reasons for discontinuation of biologics or JAKi used for patients with D2T RA in a longitudinal multicenter cohort.MethodsRA patients with clinical disease activity index (CDAI) >10 despite the use of at least two biologics or JAKi with different MOA and further treated with biologics or JAKi were included. The drug retention rates of biologics (TNFi, IL-6Ri, and CTLA4-Ig) or JAKi were estimated at 12 months using the Kaplan-Meier method and adjusted for potential confounders (age, sex, disease duration, concomitant MTX and PSL use, and the number of switched biologics or JAKi) using Cox proportional hazards models.ResultsA total of 251 treatment courses (TCs) from 167 patients were included (TNFi: 97 TCs, IL-6Ri: 67 TCs, CTLA4-Ig: 27 TCs, JAKi: 60 TCs). Baseline characteristics showed no difference in age, sex, disease duration, ACPA positivity, CDAI, and concomitant MTX and PSL use between the four groups. Drug retention excluding non-toxic reasons and remission was significantly higher in patients treated with JAKi or IL-6Ri than in patients treated with TNFi or CTLA4-Ig (P=0.00172). Multivariate analysis using Cox proportional hazards models demonstrated that discontinuation of the drug was associated with the use of TNFi or CTLA4-Ig (HR: 3.29, 95%CI: 1.15-9.42, P=0.027) and concomitant PSL use (HR: 1.14, 95%CI: 1.04-1.26, P=0.0084). In terms of disease activity evaluated with CDAI, no difference was observed between the four groups at 3 months (P=0.90), at 6 months (P=0.77), and at 12 months (P=0.75).ConclusionIn patients with D2T RA, JAKi or IL-6Ri may have treatment advantages compared with TNFi or CTLA4-Ig.References[1] EULAR definition of difficult-to-treat rheumatoid arthritis.Nagy G, Roodenrijs NMT, Welsing PM, Kedves M, Hamar A, van der Goes MC, Kent A, Bakkers M, Blaas E, Senolt L, Szekanecz Z, Choy E, Dougados M, Jacobs JW, Geenen R, Bijlsma HW, Zink A, Aletaha D, Schoneveld L, van Riel P, Gutermann L, Prior Y, Nikiphorou E, Ferraccioli G, Schett G, Hyrich KL, Mueller-Ladner U, Buch MH, McInnes IB, van der Heijde D, van Laar JM.Ann Rheum Dis. 2021 Jan;80(1):31-35.[2] Prevalence and predictive factors of difficult-to-treat rheumatoid arthritis: the KURAMA cohort.Watanabe R, Hashimoto M, Murata K, Murakami K, Tanaka M, Ohmura K, Ito H, Matsuda S.Immunol Med. 2021 May 25:1-10.Disclosure of InterestsRyu Watanabe Speakers bureau: Eli Lilly, Mitsubishi Tanabe, Pfizer, Sanofi, AbbVie, Asahi Kasei, Eisai, Bristol-Myers Squibb, UCB Japan, Chugai, Janssen, Astellas, Nippon Shinyaku, Daiichi Sankyo, Gilead Sciences Japan, and Boehringer ingelheim., Tadashi Okano Speakers bureau: Asahi Kasei, Astellas, Abbvie, Amgen, Ayumi, Chugai, Daiichi-Sankyo, Eisai, Eli Lilly, Gilead Sciences, Janssen, Kyowa Kirin, Mitsubishi Tanabe, Novartis, Ono, Pfizer, Sanofi, Takeda, UCB, Grant/research support from: Asahi Kasei, Abbvie, Chugai, Eisai, Mitsubishi Tanabe, Shinsuke Yamada: None declared, Wataru Yamamoto: None declared, Koichi Murata Speakers bureau: Eisai Co., Ltd., Chugai Pharmaceutical Co., Ltd.; Asahi Kasei Pharma Corp.; and Mitsubishi Tanabe Pharma Co., and Daiichi Sankyo Co.

Abstract
We have measured the 3d→2p transition x rays of kaonic ^{3}He and ^{4}He atoms using superconducting transition-edge-sensor microcalorimeters with an energy resolution better than 6 eV (FWHM). We determined the energies to be 6224.5±0.4(stat)±0.2(syst) eV and 6463.7±0.3(stat)±0.1(syst) eV, and widths to be 2.5±1.0(stat)±0.4(syst) eV and 1.0±0.6(stat)±0.3(stat) eV, for kaonic ^{3}He and ^{4}He, respectively. These values are nearly 10 times more precise than in previous measurements. Our results exclude the large strong-interaction shifts and widths that are suggested by a coupled-channel approach and agree with calculations based on optical-potential models.

Abstract
Enforced enrichment of the active promoter marks trimethylation of histone H3 lysine 4 (H3K4me3) and acetylation of histone H3 lysine 27 (H3K27ac) by inhibiting histone demethylases and deacetylases is positively associated with hard tissue formation through the induction of osteo/odontogenic differentiation. However, the key endogenous epigenetic modulator of odontoblasts to regulate the expression of genes coding dentin extracellular matrix (ECM) proteins has not been identified. We focused on nuclear factor (NF)-κB inhibitor ζ (IκBζ), which was originally identified as the transcriptional regulator of NF-κB and recently regarded as the NF-κB-independent epigenetic modulator, and found that IκBζ null mice exhibit a thicker dentin width and narrower pulp chamber, with aged mice having more marked phenotypes. At 6 mo of age, dentin fluorescent labeling revealed significantly accelerated dentin synthesis in the incisors of IκBζ null mice. In the molars of IκBζ null mice, marked tertiary dentin formation adjacent to the pulp horn was observed. Mechanistically, the expression of COL1A2 and COL1A1 collagen genes increased more in the odontoblast-rich fraction of IκBζ null mice than in wild type in vivo, similar to human odontoblast-like cells transfected with small interfering RNA for IκBζ compared with cells transfected with control siRNA in vitro. Furthermore, the direct binding of IκBζ to the COL1A2 promoter suppressed COL1A2 expression and the local active chromatin status marked by H3K4me3. Based on whole-genome identification of H3K4me3 enrichment, ECM and ECM organization-related gene loci were selectively activated by the knockdown of IκBζ, which consistently resulted in the upregulation of these genes. Collectively, this study suggested that IκBζ is the key negative regulator of dentin formation in odontoblasts by inhibiting dentin ECM- and ECM organization-related gene expression through an altered local chromatin status marked by H3K4me3. Therefore, IκBζ is a potential target for epigenetically improving the clinical outcomes of dentin regeneration therapies such as pulp capping.

Abstract
We report a measurement of the D^{0} and D^{+} lifetimes using D^{0}→K^{-}π^{+} and D^{+}→K^{-}π^{+}π^{+} decays reconstructed in e^{+}e^{-}→cc[over ¯] data recorded by the Belle II experiment at the SuperKEKB asymmetric-energy e^{+}e^{-} collider. The data, collected at center-of-mass energies at or near the ϒ(4S) resonance, correspond to an integrated luminosity of 72 fb^{-1}. The results, τ(D^{0})=410.5±1.1(stat)±0.8(syst) fs and τ(D^{+})=1030.4±4.7(stat)±3.1(syst) fs, are the most precise to date and are consistent with previous determinations.

Abstract
A search for the flavor-changing neutral-current decay B^{+}→K^{+}νν[over ¯] is performed at the Belle II experiment at the SuperKEKB asymmetric energy electron-positron collider. The data sample corresponds to an integrated luminosity of 63 fb^{-1} collected at the ϒ(4S) resonance and a sample of 9 fb^{-1} collected at an energy 60 MeV below the resonance. Because the measurable decay signature involves only a single charged kaon, a novel measurement approach is used that exploits not only the properties of the B^{+}→K^{+}νν[over ¯] decay, but also the inclusive properties of the other B meson in the ϒ(4S)→BB[over ¯] event, to suppress the background from other B meson decays and light-quark pair production. This inclusive tagging approach offers a higher signal efficiency compared to previous searches. No significant signal is observed. An upper limit on the branching fraction of B^{+}→K^{+}νν[over ¯] of 4.1×10^{-5} is set at the 90% confidence level.

Abstract
Abstract
Background
Cardiac rehabilitation (CR) is a comprehensive disease management program highly recommended by heart failure (HF) guidelines. However, the prognostic effects of outpatient CR are inconsistent among recent meta-analyses which enrolled mainly younger HF with reduced ejection fraction (HFrEF). With an aging population, an increased importance of CR has been put on patients with HF with preserved ejection fraction (HFpEF).
Purpose
This study aimed to examine the prognostic effects of regularly undergoing CR for 6 months after discharge analysing nationwide cohort data including older population with HFrEF and HFpEF.
Methods
We analysed 2876 patients who hospitalised for acute HF or worsening chronic HF and capable of walking at discharge in the multicentre prospective cohort study. Frequency of outpatient CR participation of each patient was collected using medical records. We assessed CR frequency within 6 months of discharge since most collaborating hospitals conducted final follow-up examinations at 6 months. The CR group was defined as patients who underwent outpatient CR once or more per week for 6 months after discharge. The main study endpoint was a composite of all-cause mortality and HF rehospitalisation during a 2-year follow-up. We performed a propensity score-matched analysis to compare survival rates between the CR and non-CR groups. Propensity scores for each patient were produced by a logistic regression analysis with the CR group as the dependent variable and 33 potential confounders as independent variables. To evaluate events beyond 6 months, we also conducted landmark analyses at 6 months.
Results
Of the 2876 enrolled patients, 313 underwent CR for 6 months. After propensity score matching using confounding factors, 626 patients (313 pairs) were included in the survival analysis (median age: 74 years, men: 59.6%, median left ventricular ejection fraction [LVEF]: 42%). During 1006.1 person-years of follow-up, 137 patients were rehospitalised due to HF exacerbation, and 50 patients died in the matched cohort. In Cox proportional hazards model (Figure 1), CR was associated with a reduced risk of composite outcomes (hazard ratio [HR] 0.66; 95% confidence interval [CI] 0.48–0.91), all-cause mortality (HR 0.53; 95% CI 0.30–0.95), and HF rehospitalisation (HR 0.66; 95% CI 0.47–0.92). A subgroup analysis showed similar CR effects in patients with HFpEF (LVEF ≥50%) and HFrEF (LVEF <40%). However, in a landmark analysis, CR did not reduce the adverse outcomes beyond 6 months after discharge (Figure 2).
Conclusions
The findings of this study demonstrate the needs that CR should become a standard treatment for HF regardless of HF type and the necessity of periodical follow-up after completing CR program to maintain its prognostic effects.

Abstract
Abstract
Recent hemodynamic studies have demonstrated that progression of coronary atherosclerosis occurs at low wall share-stress site, whereas plaque rupture frequently occurs at high share stress site. It is well recognized that wall shear stress is relatively low along the outer walls of the bifurcation.
We investigated consecutive 140 patients (77 with acute coronary syndrome (ACS) and 63 with chronic coronary syndrome (CCS) performed PCI for LAD proximal lesions (AHA seg.6) from January 2016 to December 2019. In CCS group, entry criteria included stenosis of at least 90% in the LAD proximal lesion or at least 70% in the LAD proximal lesion and objective evidence of myocardial ischemia (inducible ischemia with either exercise or pharmacologic vasodilator stress or with pressure wire). Exclusion criteria were patients with maintenance dialysis, chronic total occlusion lesions, in-stent restenosis, and clinically diagnosed unstable angina without troponin I elevation. We measured the distance from LMT distal carina to the culprit site (Distance) and plaque location (Location) with intravascular ultrasound and angle between LMT and LAD with cardiovascular angiography analysis system (CAAS) (Angle).
The two groups were generally well balanced with regard to baseline clinical characteristics. The mean (±SD) age of the patients was 69.0±11.8 years, and 75% were men. Medication at baseline was also similar between two groups except higher prevalence of statin prescription in CCS group. The Distance was shorter and Angle was steeper in CCS group than in ACS group. The number of patients with Angle less than 150 degrees and with Location in the lateral wall side was much more in CCS group.
In this study, plaques in CCS were frequently observed at low shear stress site, whereas those in ACS at high shear stress site. Plaque progression in CCS may be associated with low wall shear stress, and high shear stress may play key role in plaque rupture in ACS. This anatomical difference can partly explain the different mechanisms of onset between of ACS and CCS.

Clin Neurol Neurosurg 2021; 209:106945.

Abstract
OBJECTIVE To investigate whether or not the fusion rate after posterior lumbar interbody fusion with cortical bone trajectory screw fixation (CBT-PLIF) is lower than after PLIF using traditional trajectory screw fixation (TT-PLIF) and whether or not the titanium-coated polyetheretherketone (PEEK) cage (TiP cage) improves fusion status compared to the same shape uncoated PEEK cage (P cage). METHODS The subjects were 37 patients undergoing TT-PLIF using P cages (P-TT group), 24 patients undergoing CBT-PLIF using P cages (P-CBT group), 32 patients undergoing TT-PLIF using TiP cages (TiP-TT group), and 20 patients undergoing CBT-PLIF using TiP cages (TiP-CBT group). All patients from the 4 groups underwent our unified PLIF procedure (total facetectomy, subtotal discectomy, and the same bone graft technique using the same shape cages) except for the screw trajectories and the surface materials of the cages. Clinical symptoms were assessed using the Japanese Orthopedic Association (JOA) score before surgery and at 2-year postoperatively. None of age at the time of surgery, gender, fused segment and preoperative JOA score showed significant differences among the 4 groups. On multiplanar reconstruction computed tomography (MPR-CT) at 6months after surgery, vertebral end plate cysts were evaluated and classified into local or diffuse cysts. Fusion status was assessed using both dynamic plain radiographs and MPR-CT at postoperative 2-year. RESULTS Neither the mean JOA score nor the mean recovery rate of the JOA score at 2-year after surgery showed significant differences among the 4 groups. The incidence of the diffuse cyst (a known predictor of non-union) was 27.0% in the P-TT group, 29.2% in the P-CBT group, 25.0% in the TiP-TT group and 25.0% in the TiP-CBT group (P > 0.05). The fusion rate was 89.2% in the P-TT group, 91.7% in the P-CBT group, 90.6% in the TiP-TT group and 90.0% in the TiP-CBT group (P > 0.05). CONCLUSIONS After our unified PLIF procedure except for the screw trajectories and the surface materials of the cages, CBT-PLIF resulted in the equivalent fusion rate to TT-PLIF and the TiP cage did not lead to the improved fusion rate compared to the same shape P cage.

Abstract
OBJECTIVE: To retrospectively evaluate the clinical outcomes of pre-operative endovascular coil embolisation (ECE) for chronic pulmonary aspergillosis (CPA).METHODS: We evaluated surgical patients with CPA between November 2016 and April 2020. Pre-operative ECE for CPA with severe adhesions was selectively performed to reduce intra-operative blood loss. ECE procedures, operative procedures, intra-operative blood loss and complications were evaluated.RESULTS: Twenty-eight patients (21 males and 7 females; median age: 55 years) were included in the study. Of the 28 patients, 8 (28.6%) underwent pre-operative ECE. Technical success rate in pre-operative ECE was 100%. The median time required for ECE procedures was 123 min. The median number of vessels embolised per procedure was 2.5. The median period between embolisation and surgery was 5 days. Major complications were observed in three patients (10.7%). There were no significant differences between patients with and without pre-operative ECE in operative time (284 vs. 365 min, respectively, P = 0.7602) and intra-operative blood loss (294 vs. 228 mL, respectively, P = 0.8987).CONCLUSIONS: Pre-operative ECE for CPA appears to be feasible and safe; however, its role in reducing intra-operative blood loss needs further investigation.

Abstract
We observed electronic K x rays emitted from muonic iron atoms using superconducting transition-edge sensor microcalorimeters. The energy resolution of 5.2 eV in FWHM allowed us to observe the asymmetric broad profile of the electronic characteristic Kα and Kβ x rays together with the hypersatellite K^{h}α x rays around 6 keV. This signature reflects the time-dependent screening of the nuclear charge by the negative muon and the L-shell electrons, accompanied by electron side feeding. Assisted by a simulation, these data clearly reveal the electronic K- and L-shell hole production and their temporal evolution on the 10-20 fs scale during the muon cascade process.

Abstract
OBJECTIVE The purpose of this study was to evaluate the effects of high tibial osteotomy (HTO) on the biological status of knee osteoarthritis (OA) using joint markers in synovial fluid (SF). METHODS Fifty patients with medial compartmental OA of the knee who underwent opening wedge HTO were enrolled. Paired SF samples from the affected knee and arthroscopic evaluation of articular cartilage were collected at the time of HTO surgery and the time of plate removal (postoperative 17 ± 4 months). The concentrations of the following SF biomarkers were measured: interleukin (IL)-1β, IL-6, IL-8, IL-10, tumour necrosis factor-α, matrix metalloproteinase (MMP)-2, MMP-3, MMP-9, MMP-13, vascular endothelial growth factor (VEGF), and cartilage oligomeric matrix protein (COMP). The Knee Society Score (KSS) and hip-knee-ankle (HKA) angle were assessed before and 2 years after HTO. RESULTS The KSS knee and function scores were significantly improved after HTO (mean changes of 36.4 and 23.7, respectively). The mean HKA angle was altered from mechanical varus (-8.6°) to valgus (5.2°). Concentrations of IL-6, IL-8, MMP-2, MMP-3, MMP-13, VEGF, and COMP in SF were significantly decreased after HTO (mean changes of -49.1%, -30.2%, -31.1%, -26.3%, -30.8%, -42.5%, and -13.7% from preoperative baseline, respectively). The cartilage status was improved in 19 cases (38%) after HTO. However, changes of all biomarkers were not significantly different between subjects with and without an improved cartilage status. CONCLUSIONS SF levels of biochemical markers for cartilage degradation and synovial inflammation were altered after HTO, suggesting an improvement in the OA disease state.

Abstract
AIM To explore changes in left ventricular (LV) function and the relationship of these changes with myocardial blood flow (MBF) evaluated by 13N-ammonia hybrid positron-emission tomography (PET)/magnetic resonance imaging (MRI) during vasodilator stress in patients with suspected coronary artery disease (CAD). MATERIALS AND METHODS Fifty-two consecutive patients with suspected CAD, who underwent 13N-ammonia PET/MRI, were enrolled. Vasodilator stress was induced by intravenous injection of adenosine. MBF and coronary flow reserve (CFR) were calculated from dynamic acquisition of 13N-ammonia PET. LV function was evaluated by MRI both at rest and during vasodilator stress. An abnormal perfusion on myocardial images was defined as a summed difference score of ≥4. RESULTS MRI showed that the LV end-diastolic volume, LV end-systolic volume, and LV ejection fraction (LVEF) remained unchanged during vasodilator stress in all patients (n=52) as well as in the patients with CFR of <2 (n=27), stress MBF of <1.3 ml/g/min (n=28), abnormal myocardial perfusion (n=30), and more than one diseased vessel (n=46). In only four patients, the LVEF measured by MRI decreased by >5% during vasodilator stress. In these four patients, CFR was lower (1.57 ± 0.12 versus 2.18 ± 0.86, p<0.01) and the number of diseased vessels was higher (2.75 ± 0.50 versus 1.48 ± 0.92, p<0.01) than in patients without post-stress LV dysfunction. CONCLUSION The LV volume and systolic function evaluated by cardiac MRI remained unchanged during vasodilator stress; however, LV dysfunction during vasodilator stress may occur in patients with severe CAD.

BACKGROUND AND PURPOSE Oscillatory shear stress could not be directly measured in consideration of direction, although cerebrospinal fluid has repetitive movements synchronized with heartbeat. Our aim was to evaluate the important of oscillatory shear stress in the cerebral aqueduct and foramen magnum in idiopathic normal pressure hydrocephalus by comparing it with wall shear stress and the oscillatory shear index in patients with idiopathic normal pressure hydrocephalus. MATERIALS AND METHODS By means of the 4D flow application, oscillatory shear stress, wall shear stress, and the oscillatory shear index were measured in 41 patients with idiopathic normal pressure hydrocephalus, 23 with co-occurrence of idiopathic normal pressure hydrocephalus and Alzheimer-type dementia, and 9 age-matched controls. These shear stress parameters at the cerebral aqueduct were compared with apertures and stroke volumes at the foramen of Magendie and cerebral aqueduct. RESULTS Two wall shear stress magnitude peaks during a heartbeat were changed to periodic oscillation by converting oscillatory shear stress. The mean oscillatory shear stress amplitude and time-averaged wall shear stress values at the dorsal and ventral regions of the cerebral aqueduct in the idiopathic normal pressure hydrocephalus groups were significantly higher than those in controls. Furthermore, those at the ventral region of the cerebral aqueduct in the idiopathic normal pressure hydrocephalus group were also significantly higher than those in the co-occurrence of idiopathic normal pressure hydrocephalus with Alzheimer-type dementia group. The oscillatory shear stress amplitude at the dorsal region of the cerebral aqueduct was significantly associated with foramen of Magendie diameters, whereas it was strongly associated with the stroke volume at the upper end of the cerebral aqueduct rather than that at the foramen of Magendie. CONCLUSIONS Oscillatory shear stress, which reflects wall shear stress vector changes better than the conventional wall shear stress magnitude and the oscillatory shear index, can be directly measured on 4D flow MR imaging. Oscillatory shear stress at the cerebral aqueduct was considerably higher in patients with idiopathic normal pressure hydrocephalus.
