Abstract
Introduction In recent years, biotherapy in orthopedics has become widespread, and platelet-rich plasma (PRP) has been readily used to treat sports injuries and osteoarthritis. Production of freeze-dried PRP (PRP-FD) results in PRP that is in powder form, allowing it to be stored for long periods at room temperature. Using this technology, we have developed Valuable Platelet-Derived Factor Concentrate Freeze Dry (VFD). However, whether VFD contains sufficient levels of bioactive substances (BS) remains unknown and retains the same levels of BS during long-term storage. In this study, we examined whether VFD contains sufficient amounts of BS and whether they retain these BS levels during long-term storage. Methods Peripheral blood was collected from 10 healthy men (mean ± SD: 46.5 ± 15 years old) and various BS, including transforming growth factor β (TGF-β), basic fibroblast growth factor (bFGF), epidermal growth factor (EGF), tissue inhibitors of metalloproteinases-1 (TIMP-1), interleukin-1 receptor antagonist (IL-1ra), matrix metallopeptidase-9 (MMP-9), and interleukin-6 (IL-6), were compared between VFD and normal PRP samples, including both leukocyte-rich PRP (LR-PRP) and leukocyte-poor PRP (LP-PRP). VFD was prepared using two rounds of centrifugation. LP-PRP and LR-PRP were activated by freezing and thawing before measurement. To evaluate the effects of long-term storage, the BS of VFD purified from five professional football players was compared between baseline and 1 year after storage. Results In terms of the growth factors, the TGF-β and EGF levels were higher in LR-PRP than in VFD and LP-PRP (p < 0.05), while the bFGF levels were higher in VFD than in the LR-PRP and LP-PRP groups (p < 0.01). In terms of anti-inflammatory cytokines, the TIMP-1 level was lower in VFD than that in the other groups (p < 0.01), whereas the IL-1ra levels were higher in VFD than those in LP-PRP (p < 0.05) and lower than those in LR-PRP (p < 0.01). In terms of inflammatory enzymes and cytokines, the IL-1ra level was higher in VFD than that in LP-PRP (p < 0.05) and lower than that in LR-PRP (p < 0.01), whereas the IL-6 levels did not differ among the groups. Furthermore, the TGF-β, bFGF, TIMP-1, and IL-1ra levels were 5.61 → 3.38 (x103 pg/μL), 61.0 → 63.0 (pg/μL), 3.4 → 2.7 (x105 pg/μL), and 14.9 → 14.5 (x103 pg/μL) at baseline and 1 year later, respectively. No significant differences in the BS levels were observed between baseline and 1 year after storage. Conclusions The VFD samples prepared in this study exhibited higher levels of anti-inflammatory cytokines than LP-PRP and contained growth factor levels similar to LP-PRP and LR-PRP. In addition, the BS levels in VFD samples were maintained after one year of storage. These results suggest that VFD can be prepared and stored and may serve as a novel treatment strategy for sports injuries in high-risk groups, such as athletes.

Abstract
BACKGROUND Real-world data on clinical characteristics and outcomes related to the use of different direct oral anticoagulants (DOACs) for cancer-associated venous thromboembolism (VTE) is lacking. METHODS The COMMAND VTE Registry-2 is a multicenter registry enrolling 5,197 consecutive patients with acute symptomatic VTE from 31 centers in Japan from January 2015-August 2020. Our study population comprised 1,197 patients with active cancer who were divided into the edoxaban (N=643, 54%), rivaroxaban (N=297, 25%), and apixaban (N=257, 22%) groups. RESULTS The cumulative 5-year incidence of recurrent VTE (9.3%, 10.2%, and 8.5%, respectively, P=0.82) and all-cause death (67.5%, 66.8%, and 63.8%, respectively, P=0.22) did not differ among the groups. Despite adjusting for confounders, the risks of recurrent VTE and all-cause death did not differ significantly among the groups. The cumulative 5-year incidence of major and clinically relevant bleeding was significantly lower in the rivaroxaban group than those in the other groups (22.6%, 14.0%, and 22.8%, P=0.04; and 37.6%, 26.8%, and 38.3%, P=0.01, respectively). After adjusting for confounders, in the rivaroxaban group, the risk for major bleeding was numerically lower (HR: 0.65, 95% CI: 0.40-1.01) and that of clinically relevant all bleeding was significantly lower (HR: 0.67, 95% CI: 0.48-0.92) than those in the edoxaban group. CONCLUSIONS The risks of recurrent VTE and all-cause death did not differ significantly among the different DOACs ; however, the risk of bleeding events could differ, with a potentially lower risk of bleeding with rivaroxaban.

Abstract
BACKGROUND Patients with unprovoked venous thromboembolisms (VTEs) can be sub-classified based on the different phenotypes using a latent class analysis (LCA), which might be useful for selecting individual management strategies. METHODS In the COMMAND VTE Registry-2 database enrolling 5197 VTE patients, the current derivation cohort consisted of 1556 patients with unprovoked VTEs. We conducted clustering with an LCA, and the patients were classified into subgroups with the highest probability. We compared the clinical characteristics and outcomes among the developed subgroups. RESULTS This LCA model proposed 3 subgroups based on 8 clinically relevant variables, and classified 592, 813, and 151 patients as Class I, II, and III, respectively. Based on the clinical features, we named Class I the younger, Class II the older with a few comorbidities, and Class III the older with many comorbidities. The cumulative 3-year anticoagulation discontinuation rate was highest in the older with many comorbidities (Class III) (39.9 %, 36.1 %, and 48.4 %, P = 0.02). There was no significant difference in the cumulative 5-year incidence of recurrent VTEs among the 3 classes (12.8 %, 11.1 %, and 4.0 % P = 0.20), whereas the cumulative 5-year incidence of major bleeding was significantly higher in the older with many comorbidities (Class III) (7.8 %, 12.7 %, and 17.8 %, P = 0.04). CONCLUSION The current LCA revealed that patients with unprovoked VTEs could be sub-classified into further phenotypes depending on the patient characteristics. Each subclass phenotype could have different clinical outcomes risks especially a bleeding risk, which could have a potential benefit when considering the individual anticoagulation strategies.

Abstract
INTRODUCTION There is limited data on the safety of direct oral anticoagulants (DOACs) in fragile patients with venous thromboembolism (VTE). MATERIALS AND METHODS We used the COMMAND VTE Registry-2 enrolling patients with acute symptomatic VTE. The study population consisted of 3928 patients receiving DOACs, who were divided into fragile (2136 patients) and non-fragile groups (1792 patients). Fragility was defined as patients of age ≥ 75 years, creatinine clearance level ≤ 50 ml/min, and/or body weight ≤ 50 kg. RESULTS The fragile group significantly more often received reduced doses of DOACs compared to the non-fragile group (51 % and 19 %, P < 0.001). The cumulative 5-year incidence of major bleeding was numerically higher in the fragile group than the non-fragile group (15.0 % and 11.1 %, P = 0.052), even with no significant excess risk after adjusting for confounders (HR 1.03, 95%CI 0.81-1.31, P = 0.78). The cumulative 5-year incidence of clinically relevant bleeding was significantly higher in the fragile group than the non-fragile group (28.6 % and 19.6 %, P < 0.001), even after adjusting for confounders (HR 1.28, 95%CI 1.08-1.53, P = 0.005). There was no significant difference in cumulative 5-year incidence of recurrent VTE between the groups (9.6 % and 8.9 %, P = 0.68), which was consistent after adjusting for confounders (HR 1.13, 95%CI 0.84-1.51, P = 0.41). CONCLUSIONS Among VTE patients receiving DOACs, fragile patients were associated with a numerically higher rate of major bleeding and a significantly increased risk of clinically relevant bleeding, but not an increased risk of recurrent VTE.

Abstract
We demonstrate cascaded nonlinear pulse compression of a Yb-doped fiber laser. The system is based on two pulse compression stages with bare single-mode fiber (SMF) and ultra-high NA (UHNA) fibers combined with two pairs of chirped mirrors. The 10 nJ, 110 fs input pulses are compressed down to 9.1 fs at 90 MHz, revealing a broadband spectrum from 800 nm to 1350 nm. This technique provides a simple approach to sub-10-fs compact Yb-doped fiber lasers for a variety of applications.

Abstract
BACKGROUND There is a paucity of data on real-world management strategies and clinical outcomes of cancer-associated venous thromboembolism (VTE) in the direct oral anticoagulants (DOACs) era. OBJECTIVES To investigate the status of cancer-associated VTE in the DOAC era. METHODS This multicenter, retrospective cohort study among 31 centers in Japan between 2015 and 2020 enrolled 5197 consecutive patients with acute symptomatic VTE, who were divided into 1507 patients (29 %) with active cancer and 3690 patients (71 %) without. RESULTS The cumulative 3-year rate of anticoagulation discontinuation was significantly higher in patients with active cancer than in those without (62.7 % vs. 59.1 %, P < 0.001). The cumulative 5-year incidence of recurrent VTE was higher in patients with active cancer than in those without (10.1 % vs. 9.1 %, P = 0.01), however, after adjusting for the confounders and competing risk of mortality, the excess risk of the active cancer group relative to the no active cancer group was no longer significant (HR: 0.95, 95 % CI: 0.73-1.24). The cumulative 5-year incidence of major bleeding was much higher in the active cancer group (20.4 % vs. 11.6 %, P < 0.001). Even after adjusting for the confounders and competing risk of mortality, the risk of the active cancer group relative to the no active cancer group remained significant (HR: 1.36, 95 % CI: 1.11-1.66). CONCLUSIONS The current large real-world registry revealed that the risk of major bleeding was still higher in patients with active cancer than in those without, leading to the frequent anticoagulation discontinuation, which has been still a huge challenge to overcome in the DOAC era.

Abstract
BACKGROUND There have been still limited data on the transition of management strategies and clinical outcomes after introduction of direct oral anticoagulant (DOAC) for cancer-associated venous thromboembolism (VTE) in the real-world clinical practice. METHODS Using the 2 series of multicenter COMMAND VTE registries in Japan enrolling consecutive patients with acute symptomatic VTE, we compared 695 patients with cancer-associated VTE in the Registry-1 of the warfarin era and 1507 patients in the Registry-2 of the DOAC era. RESULTS Regarding oral anticoagulation therapy, 576 patients (82.9 %) in the Registry-1 received warfarin, whereas 1119 patients (79.6 %) in the Registry-2 received DOACs. The cumulative 3-year incidence of discontinuation of anticoagulation was not significantly different between the 2 registries (56.7 % vs. 62.7 %, P = 0.11). The cumulative 5-year incidence of recurrent VTE was significantly lower in the Registry-2 than in the Registry-1 (17.7 % vs. 10.1 %, P < 0.001). The cumulative 5-year incidence of major bleeding was significantly lower in the Registry-2 than in the Registry-1 (26.6 % vs. 20.4 %, P = 0.045). The proportion of gastrointestinal bleeding numerically increased from the Registry-1 to the Registry-2 (46.7 % and 49.5 %), whereas that of intracranial bleeding numerically decreased from the Registry-1 to the Registry-2 (17.1 % and 14.1 %). CONCLUSIONS In the current historical comparison of cancer-associated VTE between the 2 large real-world registries, there was a striking change in the treatment strategies with decreased risks of recurrent VTE and major bleeding in the DOAC era compared with those in the warfarin era, while there seemed to be unmet needs of DOAC-related gastrointestinal bleeding.

Abstract
Chirality of massless fermions emerging in condensed matter is a key to understand their characteristic behavior as well as to exploit their functionality. However, the chiral nature of massless fermions in Dirac semimetals has remained elusive, due to equivalent occupation of carriers with the opposite chirality in thermal equilibrium. Here, we show that the isospin degree of freedom, which labels the chirality of massless carriers from a crystallographic point of view, can be injected by circularly polarized light. Terahertz Faraday rotation spectroscopy successfully detects the anomalous Hall conductivity by a light-induced isospin polarization in a three-dimensional Dirac semimetal, Cd3As2. Spectral analysis of the Hall conductivity reveals a long scattering time and a long decay time, which are characteristic of the isospin. The long-lived, robust, and reversible character of the isospin promises a potential application of Dirac semimetals in future information technology.

Abstract
INTRODUCTION This study aimed to compare the vascular enhancement and radiation dose in preoperative transcatheter aortic valve implantation (TAVI) computed tomography (CT) with a reduced contrast medium (CM) using volume scans in 256-multidetector row CT (MDCT) with a standard CM using 64-MDCT. METHODS This study included 78 patients with preoperative TAVI CT with either 64- or 256-MDCT. The CM was injected at 1.5 mL/kg in the 64-MDCT group and 1.0 mL/kg in the 256-MDCT group. We compared vascular enhancement of the aortic root and access routes, image quality (IQ) scores, and radiation dose in both groups. RESULTS Despite the reduced CM (by 33 %) in the 256-MDCT group, the mean vascular enhancement of the right and left subclavian arteries was significantly higher than that in the 64-MDCT group [284 and 267 Hounsfield units (HU) vs. 376 and 359 HU; p < 0.05]; however, no significant differences in the mean vascular enhancement in the ascending aorta, abdominal aorta at the celiac level, and bilateral common femoral arteries were observed between the two groups (p > 0.05 for all). The median IQ scores at the aortic root were higher in the 256-MDCT group than in the 64-MDCT group (3 vs. 4; p < 0.05), and those at the femoral access routes were comparable (4 vs. 4; p = 0.33). The mean effective dose was significantly reduced by 30 % in the 256-MDCT group (23.6 vs. 16.3 mSv; p < 0.05). CONCLUSION In preoperative TAVI CT, volume scans using 256-MDCT provide comparable or better vascular enhancement and IQ with a 30 % reduction in CM and radiation dose than those using 64-MDCT. IMPLICATIONS FOR PRACTICE Volume scan using 256-MDCT for preoperative TAVI CT may reduce CM and radiation dose in TAVI patients with renal dysfunction.

Abstract
BACKGROUND/AIMS This study aimed to assess the efficacy and sterility of stored platelet-rich plasma (PRP) eye-drops for corneal epithelial wound healing compared with those of autologous serum (AS) eye-drops. METHODS At our single institution, PRP and AS eye-drops were prepared using peripheral blood obtained from six healthy volunteers and stored at 4°C. Platelet and leucocyte counts and transforming growth factor (TGF)-β1, epidermal growth factor (EGF), and fibronectin levels were assessed during storage for up to 4 weeks. Sterility was assessed by culturing 4-week poststorage samples. PRP, AS, and phosphate-buffered saline (PBS) eye-drop efficacies were compared using corneal epithelial wound healing assays in vitro and in vivo and monitoring wound areas under a microscope every 3 hours. RESULTS Higher platelet and lower leucocyte counts were seen in PRP than in whole blood on the day of preparation. After storage, TGF-β1, EGF, and fibronectin levels were significantly higher in PRP than in AS eye-drops. In vitro and in vivo, PRP eye-drops used on the day of preparation significantly promoted corneal epithelial wound healing compared with PBS. Moreover, PRP eye-drops stored for 4 weeks significantly promoted corneal wound healing compared with PBS and AS eye-drops. CONCLUSION PRP eye-drops stored at 4°C for 4 weeks promoted corneal epithelial wound healing with higher levels of growth factors than those observed in AS eye-drops, while maintaining sterility, suggesting that this preparation satisfies the unmet medical needs in the treatment of refractory keratoconjunctival epithelial disorders.

Abstract
BACKGROUND There has been limited data on anticoagulation strategies and long-term recurrence in patients with venous thromboembolism (VTE) in the era of direct oral anticoagulant (DOAC). METHODS The COMMAND VTE Registry-2 is a multicenter retrospective cohort study enrolling 5197 consecutive patients with acute symptomatic VTE between January 2015 and August 2020 among 31 centers in Japan. In this primary report, the entire cohort was divided into 5 groups; major transient risk factors (N = 475, 9.1%), minor transient risk factors (N = 788, 15%), unprovoked (N = 1913, 37%), non-malignant persistent risk factors (N = 514, 9.9%), and active cancer (N = 1507, 29%) groups. RESULTS DOACs were administered in 79% of patients who received oral anticoagulants. Discontinuation of anticoagulant at 1 year was most frequent in the major transient risk factors group (57.2%, 46.3%, 29.1%, 32.0%, and 45.6%). The cumulative 5-year incidence of recurrent VTE was lowest in the major transient risk factors group (2.6%, 6.4%, 11.0%, 12.1%, and 10.1%, P < 0.001). The cumulative 5-year incidence of major bleeding was highest in the active cancer group (9.8%, 11.4%, 11.0%, 15.5%, and 20.4%, P < 0.001). After discontinuation of anticoagulation therapy, the cumulative 5-year incidence of recurrent VTE was highest in the unprovoked group (3.3%, 11.0%, 24.9%, 17.5%, and 11.8%, P < 0.001). CONCLUSIONS In this large real-world VTE registry, anticoagulation strategies and long-term recurrence widely differed depending on the baseline characteristics. Detailed risk stratifications of recurrent VTE could be useful for decision-making of anticoagulation strategies, whereas the bleeding-risk assessment might be especially important in the era of DOAC.

Abstract
BACKGROUND The RIETE score could be specifically useful for identification of low-risk pulmonary embolism (PE) patients for home treatment. However, the external validation of the RIETE score has been limited. METHODS The COMMAND VTE Registry is a multicenter registry enrolling consecutive patients with acute symptomatic venous thromboembolism (VTE). The current study population consisted of 1479 patients with acute PE, who were divided into 2 groups; RIETE scores of 0 (N = 260) and ≥ 1 (N = 1219). RESULTS The cumulative 10-day and 30-day incidences of a composite endpoint of all-cause death, recurrent PE, or major bleeding were lower in patients with the RIETE score of 0 than in those with the RIETE score of ≥1 (10-day: 0.4 % vs. 6.7 %, P < 0.001, and 30-day: 0.4 % vs. 10.0 %, P < 0.001). The area under the receiver-operating characteristic curve (AUC) in the RIETE score for the 10-day composite endpoint showed numerically better predictive ability than that in the sPESI score (0.77 vs. 0.73, P = 0.07), and the AUC in the RIETE score for the 30-day composite endpoint showed significantly better predictive ability than that in the sPESI score (0.77 vs. 0.71, P = 0.003). CONCLUSIONS The RIETE score was well validated in the current large real-world registry. The RIETE score of 0 could identify patients with reasonably low risks of the 10-day and 30-day composite endpoint of all-cause death, recurrent PE, or major bleeding.

Abstract
Background Peripheral venous pressure (PVP) has been shown to be a reliable surrogate for right atrial pressure in assessing congestion in patients with heart failure (HF). Liver fibrosis markers and scores can be useful in assessing organ injury in patients with acute HF. This study aimed to investigate the association of liver fibrosis markers and scores with PVP in patients with acute HF. Methods and Results The 7S domain of the collagen type IV N-terminal propeptide (P4NP 7S), aspartate aminotransferase-to-platelet ratio index, fibrosis-4, and nonalcoholic fatty liver disease fibrosis score were determined along with PVP measurements before discharge in 229 patients with acute HF. The strongest correlation with PVP was found for P4NP 7S (Pearson r=0.40). Patients with high P4NP 7S levels (≥median [6.2 ng/mL]) had an increased risk of cardiovascular death or HF hospitalization (adjusted hazard ratio [HR], 1.80 [95% CI, 1.09-3.04], P=0.02). The concomitant high PVP (≥mean [8 mm Hg])/high P4NP 7S group, in contrast to the high PVP/low P4NP 7S or low PVP/high P4NP 7S group, had a significant risk relative to the low PVP/low P4NP 7S group for cardiovascular death or HF hospitalization (adjusted HR, 2.63 [95% CI, 1.43-5.05], P=0.002). A sustained elevation in PVP for 1 month postdischarge was associated with a persistent increase in P4NP 7S. Conclusions The study demonstrated the relationship between the liver fibrosis marker P4NP 7S and congestion. PVP and P4NP 7S could be useful for assessing congestion-related organ injury and predicting prognosis in patients with acute HF.

Abstract
We propose a quantitative method to determine the thermal dissipation dimensionality to laser ablation. We derived an analytical expression for the melting condition due to a single pulse for arbitrary spot diameters and pulse durations, which explicitly contains the dimensionality of the thermal diffusion process. As a demonstration, we compared the analytical expression with multi-shot ablation thresholds measured over pulse durations of more than six orders of magnitude for copper. The result shows that the thermal dissipation processes dominate for pulse durations longer than 5 ps, while nonthermal processes begin to dominate for shorter pulse durations.

Abstract
We experimentally elucidate the origin of the anomalous Hall conductivity in a three-dimensional Dirac semimetal, Cd_{3}As_{2}, driven by circularly polarized light. Using time-resolved terahertz Faraday rotation spectroscopy, we determine the transient Hall conductivity spectrum with special attention to its sign. Our results clearly show the dominance of direct photocurrent generation assisted by the terahertz electric field. The contribution from the Floquet-Weyl nodes is found to be minor when the driving light is in resonance with interband transitions. We develop a generally applicable classification of microscopic mechanisms of light-induced anomalous Hall conductivity.

Abstract
BACKGROUND Drug-coated balloons (DCBs) have significantly changed endovascular therapy (EVT) for femoropopliteal artery (FPA) disease, in terms of the expansion of indications for EVT for symptomatic lower extremity arterial disease (LEAD). However, whether there is a difference in the performance among individual DCBs has not yet been fully discussed. The present sub-analysis of real-world data from a prospective trial of first-generation DCBs compared the clinical outcomes between high- and low-dose DCBs using propensity score matching methods. The primary endpoint was the restenosis-free and revascularization-free rates at 1 year. RESULTS We compared 592 pairs matched for patient and lesion characteristics using propensity score matching among a total of 2,507 cases with first-generation DCBs (592 and 1,808 cases in the Lutonix low-dose and In.PACT Admiral high-dose DCB groups, respectively). There were no differences in patient/lesion characteristics, procedural success rates, or complications between the two groups. First-generation low-dose DCB had significantly lower patency (73.3% [95% confidence interval, 69.6%-77.3%] in the low-dose DCB group versus 86.2% [84.1%-88.3%] in the high-dose DCB group; P < 0.001) and revascularization-free (84.9% [81.9%-88.1%] versus 92.5% [90.8%-94.1%]; P < 0.001) rates. Chronic kidney disease on dialysis, cilostazol use, anticoagulant use, and severe calcification had a significant interaction effect in the association (all P < 0.05). CONCLUSIONS EVT to FPA with first-generation DCBs had inferior low-dose patency outcomes as compared with high-dose outcomes in the present cohort.

Abstract
We describe a setup of time-, spin-, and angle-resolved photoemission spectroscopy (tr-SARPES) employing a 10.7 eV (λ = 115.6 nm) pulse laser at a 1 MHz repetition rate as a probe photon source. This equipment effectively combines the technologies of a high-power Yb:fiber laser, ultraviolet-driven harmonic generation in Xe gas, and a SARPES apparatus equipped with very-low-energy-electron-diffraction spin detectors. A high repetition rate (1 MHz) of the probe laser allows experiments with the photoemission space-charge effects significantly reduced, despite a high flux of 1013 photons/s on the sample. The relatively high photon energy (10.7 eV) also brings the capability of observing a wide momentum range that covers the entire Brillouin zone of many materials while ensuring high momentum resolution. The experimental setup overcomes the low efficiency of spin-resolved measurements, which gets even more severe for the pump-probed unoccupied states, and affords the opportunity to investigate ultrafast electron and spin dynamics of modern quantum materials with energy and time resolutions of 25 meV and 360 fs, respectively.

Abstract
We demonstrate a jitter correction method for asynchronous optical sampling (ASOPS) terahertz (THz) time-domain spectroscopy using two free-running oscillators. This method simultaneously records the THz waveform and a harmonic of the laser repetition rate difference, Δ f r, to monitor the jitter information for software jitter correction. By suppressing the residual jitter below 0.1 ps, the accumulation of the THz waveform is achieved without losing the measurement bandwidth. Our measurement of water vapor successfully resolves the absorption linewidths below 1 GHz, demonstrating a robust ASOPS with a flexible, simple, and compact setup without any feedback control or additional continuous-wave THz source.

Abstract
Quantum correlation is a key concept characterizing the properties of quantum light sources and is important for developing quantum applications with superior performance. In particular, it enables photon pairs that are widely separated in the frequency domain, one in the visible region, the other in the infrared region, to be used for quantum infrared sensing without direct detection of infrared photons. Here, simultaneous multiwavelength and broadband phase matching in a nonlinear crystal could provide versatile photon-pairs source for broadband infrared quantum sensing. This paper describes direct generation and detection of two quantum-correlated photon pairs produced via simultaneous phase-matched processes in periodic crystals. These simultaneous photon pairs provide a correlated state with two frequency modes in a single pass. To confirm the correlation, we constructed an infrared-photon counting system with two repetition-synchronized fiber lasers. We performed coincidence measurements between two pairs, 980 nm and 3810 nm, and 1013 nm and 3390 nm, which yielded coincidence-to-accidental ratios of 6.2 and 6.5, respectively. We believe that our novel correlated light source with two separate pairs in the visible and infrared region complements a wide-range of multi-dimensional quantum infrared processing applications.

Abstract
BACKGROUND There is still a scarcity of data on the relation between age and long-term clinical outcomes of patients with venous thromboembolism (VTE). METHODS The COMMAND VTE Registry was a multicenter registry enrolling 3027 consecutive patients with acute symptomatic VTE in Japan between January 2010 and August 2014. We divided the entire cohort into 3 groups: patients aged <65 years (N = 1100, 36.7%), patients aged 65 ≤ and ≤ 80 years (N = 1314, 43.4%), and patients aged >80 years (N = 603, 19.9%). RESULTS Discontinuation of anticoagulation therapy during the follow-up period was most frequent in patients aged <65 years (44%, 38% and 33%, P < 0.001). The cumulative 5-year incidences were 12.7%, 9.8% and 7.4% for recurrent VTE, 10.8%, 12.2% and 14.9% for major bleeding, and 23.0%, 31.4%, and 38.6% for all-cause death. Adjusting for cofounders and taking into account the competing risk of all-cause death, the lower risk of patients aged >80 years, and those aged 65 ≤ and ≤ 80 years relative to those aged <65 years remained significant for recurrent VTE (65 ≤ age ≤ 80 years, HR: 0.71, 95%CI: 0.53-0.94, P = 0.02; age > 80 years, HR: 0.59, 95%CI: 0.39-0.89, P = 0.01), and the risk remained insignificant for major bleeding (65 ≤ age ≤ 80 years, HR: 1.00, 95%CI: 0.76-1.31, P = 0.98; age > 80 years, HR: 1.17, 95%CI: 0.83-1.65, P = 0.37). CONCLUSIONS In the current real-world VTE registry, there was no significant difference in the risk of major bleeding depending on different age groups, while younger patients showed an excess risk for recurrent VTE compared with older patients.

Abstract
[Purpose] Walking ability should be predicted as early as possible in acute stroke patients. The purpose is to construct a prediction model for independent walking from bedside assessments using classification and regression tree analysis. [Participants and Methods] We conducted a multicenter case-control study with 240 stroke patients. Survey items included age, gender, injured hemisphere, the National Institute of Health Stroke Scale, the Brunnstrom Recovery Stage for lower extremities, and "turn over from a supine position" from the Ability for Basic Movement Scale. The National Institute of Health Stroke Scale items, such as language, extinction, and inattention, were grouped under higher brain dysfunction. We used the Functional Ambulation Categories to classify patients into independent (four or more the Functional Ambulation Categories; n=120) and dependent (three or fewer the Functional Ambulation Categories; n=120) walking groups. A classification and regression tree analysis was used to create a model to predict independent walking. [Results] The Brunnstrom Recovery Stage for lower extremities, "turn over from a supine position" from the Ability for Basic Movement Scale, and higher brain dysfunction were the splitting criteria for classifying patients into four categories: Category 1 (0%), severe motor paresis; Category 2 (10.0%), mild motor paresis and could not turn over; Category 3 (52.5%), with mild motor paresis, could turn over, and had higher brain dysfunction; and Category 4 (82.5%), with mild motor paresis, could turn over, and no higher brain dysfunction. [Conclusion] We constructed a useful prediction model for independent walking based on the three criteria.

Abstract
Linelike features in TeV γ rays constitute a "smoking gun" for TeV-scale particle dark matter and new physics. Probing the Galactic Center region with ground-based Cherenkov telescopes enables the search for TeV spectral features in immediate association with a dense dark matter reservoir at a sensitivity out of reach for satellite γ-ray detectors, and direct detection and collider experiments. We report on 223 hours of observations of the Galactic Center region with the MAGIC stereoscopic telescope system reaching γ-ray energies up to 100 TeV. We improved the sensitivity to spectral lines at high energies using large-zenith-angle observations and a novel background modeling method within a maximum-likelihood analysis in the energy domain. No linelike spectral feature is found in our analysis. Therefore, we constrain the cross section for dark matter annihilation into two photons to ⟨σv⟩≲5×10^{-28} cm^{3} s^{-1} at 1 TeV and ⟨σv⟩≲1×10^{-25} cm^{3} s^{-1} at 100 TeV, achieving the best limits to date for a dark matter mass above 20 TeV and a cuspy dark matter profile at the Galactic Center. Finally, we use the derived limits for both cuspy and cored dark matter profiles to constrain supersymmetric wino models.

Abstract
Data on the impact of heart rate (HR) at diagnosis on clinical outcomes in patients with acute pulmonary embolism (PE) remain scarce. The present study population consisted of 1,532 patients with PE; the patients were divided into 4 groups, including (1) HR <80 beats/min (n = 451, 29%), (2) 80 ≤HR <100 beats/min (n = 620, 40%), (3) 100 ≤HR <110 beats/min (n = 215, 14%), and (4) HR ≥110 beats/min (n = 246, 16%). The cumulative 30-day incidences of all-cause death were significantly higher in the 100 ≤HR <110 and HR ≥110 beats/min groups than in the HR <80 beats/min group. Incidences were 2.7%, 3.6%, 6.6%, and 5.7% (p = 0.04) in the HR <80 beats/min, 80 ≤HR <100 beats/min, 100 ≤HR <110 beats/min, and HR ≥110 beats/min groups, respectively. With the HR <80 beats/min group as reference, the 100 ≤HR <110 and HR ≥110 groups, but not the 80 ≤HR <100 group, were significantly associated with an increased risk of 30-day all-cause death. Hazard ratio was 2.53 (95% confidence interval [CI] 1.17 to 5.56, p = 0.02) for the 80 ≤HR <100 beats/min group, 2.20 (95% CI 1.02 to 4.84, p = 0.046) for the 100 ≤HR <110 beats/min group, and 1.34 (95% CI 0.67 to 2.79, p = 0.41) for the HR ≥110 beats/min group. The cumulative 30-day incidences of all-cause death in patients with simplified Pulmonary Embolism Severity Index score = 0 were 0.6%, 0.3%, and 0.7% when based on cut-off values of HR ≥110 beats/min, HR ≥100 beats/min, and ≥80 beats/min, respectively. Patients with moderate tachycardia (100 ≤HR <110) seemed to be at comparable risk of 30-day all-cause death to those with HR ≥110 beats/min and at higher risk of 30-day all-cause death than those with HR <80 beats/min; this may suggest a potential benefit of the alternative cut-off value of HR ≥100 beats/min in the simplified Pulmonary Embolism Severity Index score for identification of low-risk patients.

Abstract
There is a paucity of data on management strategies and clinical outcomes after recurrent venous thromboembolism (VTE). In a multicenter registry enrolling 3027 patients with acute symptomatic VTE, the current study population was divided into the following 3 groups: (1) First recurrent VTE during anticoagulation therapy (N = 110); (2) First recurrent VTE after discontinuation of anticoagulation therapy (N = 116); and (3) No recurrent VTE (N = 2801). Patients with first recurrent VTE during anticoagulation therapy more often had active cancer (45, 25 and 22%, P < 0.001). Among 110 patients with first recurrent VTE during anticoagulation therapy, 84 patients (76%) received warfarin at recurrent VTE with the median prothrombin time-international normalized ratio (PT-INR) value at recurrent VTE of 1.6, although patients with active cancer had a significantly higher median PT-INR value at recurrent VTE compared with those without active cancer (2.0 versus 1.4, P < 0.001). Within 90 days after recurrent VTE, 23 patients (20.9%) during anticoagulation therapy and 24 patients (20.7%) after discontinuation of anticoagulation therapy died. Active cancer was a major cause of recurrent VTE during anticoagulation therapy as a patient-related factor, while sub-optimal intensity of anticoagulation therapy was a major cause of recurrent VTE during anticoagulation therapy as a treatment-related factor, particularly in patients without active cancer.

Abstract
A pulsed sextupole magnet was used for beam injection at the KEK-Photon Factory (KEK-PF). During the top-up injection, oscillation of the stored beam was observed. To investigate this issue, a compact pick-up probe has been developed for measuring peak fields around the zero-magnetic-field region where the stored beam passes. The probe has two coils: a main coil and a background coil. The width and length of the main coil are only 3.2 and 5.8 mm, respectively. The voltage signal from the background coil is subtracted from that of the main coil to obtain an effective voltage signal. The results show that the peak field of a pulsed magnet can be measured with a sufficient accuracy for magnetic field mapping. A magnetic field signal with an amplitude of 2.2 × 10-4 T was measured clearly. The longitudinal field structure that contains the magnetic field generated by the eddy-current effect was observed, which explains the oscillation of the stored beam at the KEK-PF.

Abstract
OBJECTIVE This study aimed to determine whether the intra-articular injection of human adipose-derived mesenchymal stem cells (ADSCs) protects against the progression of murine post-traumatic osteoarthritis. DESIGN ADSCs were isolated from human abdomen or buttock adipose tissues. In in vitro study, ADSCs conditioned medium was added to human chondrocytes pre-treated with interleukin-1β (IL-1β), and resultant gene expression of target inflammatory genes was measured by real-time quantitative polymerase chain reaction. A mouse model of knee osteoarthritis was generated by unilaterally transecting the medial meniscus in the right hind limb of 20 female C57BL/6 mice. Mice were randomly assigned to 2 treatment groups that received 6 µl intra-articular injections of either phosphate-buffered saline (control) or 2 × 104 cells/μl of ADSCs 14, 28, and 42 days post-surgery. Mice were euthanized 84 days post-surgery and histological and micro-computed tomography evaluation of knee joints were analyzed. Hind limb weight-bearing distribution was measured pre-surgery and 28 and 84 days post-surgery. RESULTS Conditioned medium from cultured human adipose-derived mesenchymal stem cells suppressed the expression of target inflammatory genes in chondrocytes pre-treated with IL-1β, suggesting anti-inflammatory properties (P < 0.01). Histological analyses indicated that the progression of destabilization of medial meniscus-induced knee osteoarthritis was suppressed by the administration of ADSCs compared with control group at medial femorotibial joint in vivo. This protective effect was related to a reduction in articular cartilage loss. CONCLUSION The intra-articular injection of ADSCs suppressed articular cartilage loss in a mouse model of knee osteoarthritis, possible through anti-inflammatory mechanisms.

Abstract
INTRODUCTION The elevated cytokine levels in patients suffering from anterior cruciate ligament (ACL) rupture may lead to acute post-traumatic arthritis (APTA) and post-traumatic osteoarthritis (PTOA). Due to its chondrogenerative and anti-inflammatory effect, platelet-rich plasma (PRP) therapy is expected to show a positive outcome in APTA and PTOA. The proposed trial aims to quantitatively measure the efficacy of PRP injection in arresting post-traumatic cartilage degeneration among patients after ACL reconstruction. METHODS AND ANALYSIS This will be a single-blind, randomised, prospective, controlled clinical trial designed following the Consolidated Standards of Reporting Trials guidelines. After ACL reconstruction, 80 patients will be randomised to receive either leucocyte-poor PRP injection after joint aspiration or a placebo control group receiving only joint aspiration. Participants (age 20-49 years) will be those who have undergone ACL reconstruction within the past 2 weeks with a body mass index<35 and Kellgren Lawrence osteoarthritis grade<2. The primary outcome will include MRI-T2 values of knee cartilage at 6 months. The secondary outcomes will include pain assessment by Visual Analogue Scale, Knee injury and Osteoarthritis Outcome Score, blood and urine test, physical findings, measurements for muscle strength and joint stability. ETHICS AND DISSEMINATION The study was approved by The Independent Ethics Committee for Clinical Trials of the Japanese Association for the Promotion of State-of-the-Art Medicine. Results of the trial and each of the outcomes will be shared via conferences and publication in a peer-reviewed journal. TRIAL REGISTRATION NUMBER jRCTb030200391.

Abstract
Using broadband (12-45 THz) multi-terahertz spectroscopy, we show that stimulated Rayleigh scattering dominates the transient optical conductivity of cadmium arsenide, a Dirac semimetal, under an optical driving field at 30 THz. The characteristic dispersive line shape with net optical gain is accounted for by optical transitions between light-induced Floquet subbands, strikingly enhanced by the longitudinal plasma mode. Stimulated Rayleigh scattering with an unprecedentedly large refractive index change may pave the way for slow light generation in conductive solids at room temperature.

Abstract
Abstract
Background
Patients with hypertrophic cardiomyopathy (HCM) are at high risk of lethal arrhythmias, and implantable cardioverter defibrillators (ICD) are widely used for prevention of sudden cardiac death (SCD). Apical HCM is a phenotype variant of HCM, with hypertrophy predominantly affecting apex, that was initially described 30 years ago. Apical HCM patients may have different clinical prognosis compared with other subsets of HCM. In previous studies, apical HCM patients seem to have a more benign prognosis than other types of HCM. However, little is known about the long-term outcomes of apical HCM patients and there are many unclear points. Moreover, there are few reports about the clinical prognosis in apical HCM patients with an ICD.
Objective
The aim of this study is to identify the difference between the prognosis of apical and the other types of HCM patients with an ICD.
Methods
We retrospectively analyzed the database of our ICD clinic. All subjects underwent ICD implantation between October 2006 and September 2018. We classified HCM patients into LV outflow tract obstruction (LVOTO) and midventricular obstruction (MVO), apical HCM and other non-obstructive types. We divided all the patients into apical and other types of HCM, and examined their background, incidence of appropriate ICD therapies, hospitalization for heart failure, electrical storm and death.
Results
A total of consecutive 64 Japanese HCM patients with an ICD (follow-up period, 86±24 months; age, 65±14 years; male sex, 83%; left ventricular ejection fraction, 56±14%; LV max wall-thickness, 19±7mm; LV apical aneurysm, 9.4%; 5-year risk of SCD, 4.4±2.1) were enrolled in this study. We classified them into 14 apical HCM and 50 other types of HCM patients. The clinical characteristics and major clinical events of these patients are shown in the Table 1. During the follow-up periods, there were no significant differences in the incidence of electrical storm, hospitalization for heart failure and death between the 2 groups (p=0.11; p=0.60; p=0.39). Appropriate ICD therapies occurred in 6 of 14 (43%) patients with apical HCM and 5 of 50 (10%) patients with other types of HCM (p=0.010). The risk factors of patients with apical HCM patients are shown in Table 2.
Conclusions
Appropriate ICD therapy was more prevalent in patients with apical HCM, compared to patients with other types of HCM. Aggressive intervention such as catheter ablation for ventricular tachycardia and ventricular fibrillation may be considered in patients with apical HCM and higher score of 5-year risk of SCD. Further studies are needed to clarify the manifestations and long-term outcome of apical HCM patients.

Abstract
Abstract
Background
For decades, ICD is a well-established therapy for improving prognosis of structural heart disease with severe cardiac dysfunction, and ICD for primary prophylaxis against sudden cardiac death were routinely provided. However, long-term prognosis and clinical course are different in each individual patient with an ICD, and it is moreover unclear what kind of factors might have influences on their clinical outcomes.
Purpose
The aim of this study is to clarify long-term prognosis and predictors of future major adverse cardiac events (MACEs) in HFrEF patients with an ICD as primary prophylaxis in Japanese population.
Methods
We retrospectively analyzed our ICD database. Patients underwent primary prophylactic ICD implantation from 2006 to 2020 at our institute and met the criteria of ICD recommendation of the latest Japanese guideline. Its requirements are receiving optimal medication therapy, symptomatic heart failure (New York Heart Association classification II or greater), and severe cardiac dysfunction (left ventricular ejection fraction (LVEF) is 35% or less). Additionally, prior NSVT is considered Class I ICD recommendation. In the case of ischemic cardiomyopathy (ICM), ICD implantation was done at least 40 days after myocardial infarction and at least 90 days after revascularization. MACEs were defined as composite outcome of cardiovascular death, heart failure hospitalization, and appropriate ICD therapies.
Results
A total of 148 consecutive patients were enrolled (male, 120 (81%); age, 62.1±11.8 years; LVEF, 23.0±5.86%; left ventricular end-diastolic diameter (LVDd), 67.6±9.26mm; paroxysmal or persistent atrial fibrillation (AF), 38 (26%); NSVT, 113 (76%); use of class III antiarrhythmic drugs, 48 (32%); ICM, 49 (33%); cardiac resynchronization therapy (CRT), 63 (43%)). One hundred twenty patients (81%) were programmed with a shock-only zone over 200 beats per minute. The median follow-up duration was 58.5 months. Among those 148 patients, MACEs were occurred to 60 patients (41%). As a result of dividing all patients into two groups by the occurrence of MACE, LVEF and LVDd were worse in MACE(+) group, whereas, MACE(−) had greater number of co morbidities. The results of cox-regression analysis showed LVDd (HR: 1.07, 95% CI: 1.03–1.12, p<0.001), AF (HR: 2.88, 95% CI: 1.56–5.31, p<0.001) and ICM (HR: 1.78, 95% CI: 1.00–3.16, p=0.049) were the independent predictors of MACEs (Table). However, initial ICD programming was not related to the occurrence of MACE.
Conclusions
The incidence of MACEs in patients with an ICD and severe HFrEF was substantially high in this Japanese population. Etiology of ICM, left ventricle size, and AF were the potential risk factors for future MACEs.

Abstract
Abstract
Background
Triglyceride (TG) deposit cardiomyovasculopathy (TGCV) is a novel cardiovascular disorder and was recently encoded as an orphan disease in Europe (ORPHA code: 565612). Defective intracellular lipolysis results in TG accumulation in the myocardium and coronary arteries in TGCV. The myocardial washout rate (WR) of iodine-123-β-methyl-p-iodophenylpentadecanoic acid (BMIPP) is an essential indicator to evaluate myocardial lipolysis in vivo, and decreased WR (<10%) of BMIPP is one of the essential items of diagnostic criteria for TGCV.
Purpose
To clarify clinical findings of TGCV including comorbid conditions and laboratory findings.
Methods
We enrolled 234 patients who underwent BMIPP scintigraphy between September 2015 and July 2019. The distributions of TGCV in each comorbidity, cardiac functions and laboratory findings were investigated.
Results
In total, 104 patients were diagnosed with definitive TGCV. The BMIPP WR of TGCV patients was −1.37±10.6%. TGCV patients had various comorbid conditions, including coronary artery disease (75%), diabetes mellitus (56%), and heart failure (21%). Left ventricular ejection fraction (LVEF) of TGCV patients was significantly lower than that of non-TGCV patients (38.1±18.0% vs. 43.6±18.9%, p-value=0.026). Moreover, among those who did not take lipid-lowering drugs, there was no difference in the serum TG level between TGCV and non-TGCV patients (TGCV: n=44, 127±84.6 mg/dL, non-TGCV: n=66, 133±70.7 mg/dL, p-value=0.73).
Conclusions
TGCV patients showed multiple coexistence of coronary artery disease, diabetes mellitus, or heart failure with lower LVEF. Serum TG level was not significantly different between TGCV and non-TGCV patients. Serum TG did not affect the intracellular TG accumulation in TGCV patients directly, and this result was consistent with the pathophysiological hypothesis that the TG accumulation in the myocardial cytoplasm is due to intracellular lipase dysfunction.

Abstract
Abstract
Background
Right heart failure following left ventricular assist device (LVAD) implantation is a major complication which significantly impairs functional capacity and quality of life (QoL). Right ventricular (RV) reserve function may limit exercise capacity and QoL in LVAD patients; however, most patients show normal RV haemodynamics at rest.
Purpose
The aim of this study was to investigate whether RV reserve assessed by the changes of RV function during exercise is correlated with exercise capacity and QoL in patients with LVAD.
Methods
We prospectively examined 20 consecutive LVAD patients who were admitted to our university hospital between June 2020 and November 2021 after excluding those who were unable to perform exercise (n=8). All patients underwent invasive exercise right heart catheterisation with simultaneous echocardiography in the supine position. RV stroke work index (RVSWI) was calculated as 0.0136 × stroke volume index × (mean pulmonary artery pressure [mPAP] − right atrial pressure [RAP]) at rest and during exercise. Exercise capacity and QoL were assessed by 6-minute walk distance (6MWD) and peak oxygen consumption (VO2) in cardiopulmonary exercise testing, and the EuroQol visual analogue scale (EQ-VAS), respectively. The patients were divided into two groups according to the median ΔRVSWI (RVSWI change from rest to peak exercise) of 1.45 (interquartile range [IQR] −0.31 to 8.25) g/m2.
Results
Patients were predominantly male (75%) and the median age was 47 (IQR 38–60) years. Patients with lower ΔRVSWI had significantly higher change on RAP (P=0.019), but significantly lower change on mPAP (P<0.001) compared to those with higher ΔRVSWI. There were no significant differences in age, gender, primary aetiology of heart failure, type of LVAD devices, or echocardiographic parameters including tricuspid annular plane systolic excursion, and RVSWI at rest between the groups. ΔRVSWI during exercise were positively correlated with 6MWD (R=0.69, P<0.01) and peak VO2 (R=0.66, P<0.01) (Figure A). In addition, ΔRVSWI during exercise were positively correlated with the EQ-VAS (R=0.48, P=0.031). On the other hand, there was no significant correlation between RVSWI at rest and 6MWD (R=−0.11, P=0.63) and peak VO2 (R=0.13, P=0.95), and the EQ-VAS (R=0.11, P=0.61). During a median follow-up period of 312 (IQR 176–369) days, adverse events occurred in 3 patients (15%), including 1 death and 2 hospitalisations for major bleeding and right heart failure. Kaplan-Meier analysis revealed that the adverse events more frequently occurred in patients with lower ΔRVSWI compared to those with higher ΔRVSWI (Figure B).
Conclusions
ΔRVSWI was positively correlated with 6MWD, peak VO2 and EQ-VAS irrespective of RV function at rest. Our findings suggest that the assessment of RV reserve function using ΔRVSWI would be useful for risk stratification in patients with LVAD.

Abstract
We developed a mid-infrared spectroscopy system with high spectral resolution and a high signal-to-noise ratio using an extremely high-order germanium immersion grating. The spectroscopic system covers wavelengths from 3 to 5 µm and has a spectral resolution of 1 GHz with a single-shot bandwidth of 2 THz. We proposed a method of improving the signal-to-noise ratio and achieved a ratio of over 3000 with a data acquisition rate of 125 Hz in the presence of fluctuations in the light source and environment. A signal-to-noise ratio of 10,000 was achieved with 0.1-s integration for 100-µW mid-infrared light.

Abstract
INTRODUCTION There is still a scarcity of data on causes of long-term mortality in patients with venous thromboembolism (VTE). MATERIALS AND METHODS The COMMAND VTE Registry is a physician-initiated, retrospective, multicenter cohort study in which consecutive 3027 patients with acute symptomatic VTE among 29 centers in Japan were included between January 2010 and August 2014. We investigated detailed causes and risk factors for long-term mortality. RESULTS During a median observation period of 1218 days, a total of 764 patients died, and the prevalence of active cancer was higher in patients who died than in patients alive (61 % versus 10 %, P < 0.001). The cumulative incidences of cardiac death, pulmonary embolism (PE)-related death, bleeding death, cancer death, and non-cardiovascular non-cancer death were 2.2 %, 2.9 %, 2.0 %, 16.1 %, and 6.7 % at 5 years, respectively. The incidence of cancer death increased gradually, which was the most common cause of long-term death. Among patients without active cancer, the incidence of PE-related death increased rapidly and became a plateau beyond the acute phase, whereas the incidence of non-cardiovascular non-cancer death kept increasing, which became most common in the long term. The separate multivariable analysis among patient with and without active cancer identified independent risk factors of all-cause death including a few patient characteristics among patients with active cancer and several patient characteristics among patients without active cancer. CONCLUSIONS Cancer was the most common cause of long-term mortality, while non-cardiovascular non-cancer death became most common among patients without active cancer.

Abstract
The interaction between ultrashort laser pulses and materials in the ultrafast time domain, especially regarding the effect of laser polarization, has attracted much attention. In this study, ultrafast time-resolved single-shot birefringence microscopy is performed to observe laser-induced anisotropy. The birefringences of the optical Kerr effect and laser-induced anisotropic nanostructures by femtosecond laser pulses in silica glass are measured, and their slow axis is confirmed to correspond to the linear polarization angle of the pump light. We discuss the time variations of these birefringences in the picosecond time domain.

Abstract
BACKGROUND Vitamin K antagonist (VKA) remains an essential option for venous thromboembolism (VTE), although direct oral anticoagulants have become available. However, there is a paucity of data on the optimal intensity and quality of control for VKA in Japanese. METHODS The COMMAND VTE Registry is a multicenter registry enrolling consecutive 3027 patients with acute symptomatic VTE among 29 centers in Japan. The current study population consisted of 1938 patients who received VKA with prothrombin time-international normalized ratio (PT-INR) measurement >5 times. The primary outcome measure was a composite of symptomatic VTE recurrence or major bleeding at 1 year. The presumed optimal quality of VKA therapy was defined as the combination of PT-INR range and time in therapeutic range (TTR) with the numerically lowest event rate. RESULTS The group with TTR ≥70 % based on PT-INR range ≥1.5 and <2.0 showed the lowest cumulative incidence rate. The cumulative 1-year incidence and the adjusted risk for the primary outcome measure were significantly lower in the optimal quality group than in the non-optimal quality group (5.2 % vs. 11.7 %, p = 0.001, and HR 0.49, 95%CI 0.28-0.81). Similarly, the cumulative 1-year incidences of a recurrent VTE, major bleeding, and all-cause death were significantly lower in the optimal quality group (recurrent VTE: 2.5 % vs. 6.0 %, p = 0.02; major bleeding: 2.8 % vs. 7.0 %, p = 0.008; and all-cause death: 2.8 % vs. 12.6 %, p < 0.0001). The lower risk of the optimal quality group relative to non-optimal quality group for the clinical outcomes was consistent regardless of the etiology of VTE (active cancer, transient risk factor, and unprovoked). CONCLUSIONS The current VTE registry showed the optimal intensity of VKA therapy was target PT-INR range ≥1.5 and <2.0, which could support the current Japanese guideline recommendation, and the good quality of control for VKA therapy of TTR ≥70 % was independently associated with better outcomes.
