RESUMEN
Introduction: Endothelial cells have a crucial function in transporting and exchanging various nutrients. O-GlcNAcylation, mediated by O-GlcNAc transferase (OGT), involves the addition of N-acetylglucosamine to proteins and serves as an intracellular nutrient sensing mechanism. However, the role of O-GlcNAcylation in endothelial cells remains poorly understood. Objective: This study investigated the role of O-GlcNAcylation in endothelial cells. Methods: Endothelial-cell-specific Ogt -knockout mice (Ogt-ECKO) were generated by crossing Ogt-floxed mice (Ogt-flox) with VE-Cadherin Cre ERT2 mice. Ogt-ECKO mice and Ogt-flox control mice were subjected to a normal or high-fat diet, and their body weight, glucose metabolism, and lipid metabolism were examined. Results: Ogt-ECKO mice exhibited reduced body weight compared with Ogt-flox control mice under a high-fat diet. Lipid absorption was significantly impaired in Ogt-ECKO mice. Changes in the intercellular junctions of small intestinal lacteal endothelial cells from a button-like to a zipper-like configuration were observed. Furthermore, Ogt-ECKO mice showed decreased expression of VEGFR3. The administration of a nitric oxide donor restored lipid absorption and reversed the morphological alterations in Ogt-ECKO mice. Conclusions: These findings demonstrate the critical role of O-GlcNAcylation in endothelial cells in lipid absorption in the intestine through the modulation of lacteal junction morphology. These results provide novel insight into the metabolic regulatory mechanisms under physiological conditions and have implications for the development of new therapeutic strategies for obesity.
RESUMEN
BACKGROUND: There have been limited data on the changes in clinical outcomes after the introduction of direct oral anticoagulants (DOACs) for venous thromboembolism (VTE) in real clinical practice. We evaluated the changes in management strategies and long-term outcomes from the warfarin era to the DOAC era. METHODS AND RESULTS: We compared the 2 series of multicenter COMMAND VTE (Contemporary Management and Outcomes in Patients With Venous Thromboembolism) registries in Japan enrolling consecutive patients with acute symptomatic VTE: Registry 1: 3027 patients in the warfarin era (2010-2014) and Registry 2: 5197 patients in the DOAC era (2015-2020). The prevalence of DOAC use increased more in Registry 2 than in the Registry 1 (Registry 1: 2.6% versus Registry 2: 79%, P<0.001). The cumulative 5-year incidence of recurrent VTE was significantly lower in Registry 2 than in Registry 1 (10.5% versus 9.5%, P=0.02), and the risk reduction of recurrent VTE in Registry 2 remained significant even after adjusting the confounders (hazard ratio [HR], 0.78 [95% CI, 0.65-0.93]; P=0.005). The cumulative 5-year incidence of major bleeding was not significantly different between the 2 registries (12.1% versus 13.7%, P=0.26), and the risk of major bleeding between the 2 registries was not significantly different even after adjusting the confounders (HR, 1.04 [95% CI, 0.89-1.21]; P=0.63). CONCLUSIONS: Along with the shift from warfarin to DOACs, there was a lower risk of recurrent VTE in the DOAC era than in the warfarin era, whereas there was no apparent change in the risk of major bleeding, which might still be an unmet need even in the DOAC era.

BACKGROUND: Initial hemodynamic status in patients with acute pulmonary embolism (PE) concerns their acute clinical outcomes. Nevertheless, the characteristics of initial hemodynamic dysfunction and acute mortality in PE patients with active cancer is still controversial. METHODS: We analyzed the data of 1715 PE patients in the COMMAND VTE Registry to compare initial hemodynamic dysfunction, management strategies, and mortality outcomes at 30 days after PE diagnosis between patients with and without active cancer (N = 393 and N = 1322). RESULTS: The patients with active cancer showed lower prevalence of right ventricular dysfunction (35.4% vs. 49.5%, P < 0.001), shock (6.4% vs. 11.6%, P = 0.003), and cardiac arrest (1.8% vs. 5.5%, P = 0.002) at PE diagnosis, compared with those without. The patients with active cancer less frequently received systemic thrombolysis (4.1% vs. 12.6%, P < 0.001) than those without. There was no significant difference in the cumulative 30-day incidence of PE-related death between patients with and without active cancer (4.1% vs. 4.2%, P = 0.89). The cumulative 30-day incidence of all-cause death was significantly higher in patients with active cancer than in those without (11.5% vs. 4.9%, P < 0.001). CONCLUSIONS: PE patients with active cancer less frequently present with initial hemodynamic dysfunction at PE diagnosis, compared with those without. Nevertheless, PE patients with active cancer still show a similar risk of PE-related death and a higher risk of all-cause death at 30 days after PE diagnosis, suggesting the importance of prudent management for this patient population even if their initial hemodynamic status are not compromised.
RESUMEN
BACKGROUND: There is no established risk score for anticoagulant-related bleeding during the acute phase in patients with pulmonary embolism (PE). The PE-Syncope, Anemia, and Renal Dysfunction (PE-SARD) bleeding score was developed to predict early major bleeding but has not yet been fully externally validated. OBJECTIVES: To externally validate the PE-SARD bleeding score. METHODS: Using the COntemporary ManageMent AND outcomes in patients with Venous ThromboEmbolism (COMMAND VTE) Registry-2 database, which enrolled 5197 consecutive acute symptomatic venous thromboembolism patients among 31 centers in Japan between January 2015 and August 2020, we identified acute PE patients. We divided them into 3 groups by the score: high-risk (>2.5 points), intermediate-risk (1-2.5 points), and low-risk (0 points). The discriminating and calibration performances of the score for 30-day major bleeding were assessed. Subgroup analyses based on active cancer were also performed. RESULTS: Of 2781 eligible patients, the high-risk group accounted for 557 patients (20%), intermediate-risk group for 1412 (51%), and low-risk group for 812 (29%). Major bleeding occurred in 121 patients within 30 days. The cumulative 30-day incidence of major bleeding substantially increased in the higher risk categories by the score (high-risk group, 8.2% [95% CI, 5.9%-10.5%]; intermediate-risk group, 4.6% [95% CI, 3.5%-5.7%]; and low-risk group, 1.8% [95% CI, 0.8%-2.7%]). The discriminating power of the score was modest with a C statistic of 0.65 (95% CI, 0.61-0.70), with a good calibration performance with a score of <4 points, except for that in active cancer patients. CONCLUSION: The PE-SARD bleeding score had a modest discriminating performance with a limited calibration performance in acute PE patients without active cancer.
RESUMEN
Acetate is a short-chain fatty acid (SCFA) that is produced by microbiota in the intestinal tract. It is an important nutrient for the intestinal epithelium, but also has a high plasma concentration and is used in the various tissues. Acetate is involved in endurance exercise, but its role in resistance exercise remains unclear. To investigate this, mice were administered either multiple antibiotics with and without oral acetate supplementation or fed a low-fiber diet. Antibiotic treatment for 2 weeks significantly reduced grip strength and the cross-sectional area (CSA) of muscle fiber compared with the control group. Intestinal concentrations of SCFAs were reduced in the antibiotic-treated group. Oral administration of acetate with antibiotics prevented antibiotic-induced weakness of skeletal muscle and reduced CSA of muscle fiber. Similarly, a low-fiber diet for 1 year significantly reduced the CSA of muscle fiber and fecal and plasma acetate concentrations. To investigate the role of acetate as an energy source, acetyl-CoA synthase 2 knockout mice were used. These mice had a shorter lifespan, reduced skeletal muscle mass and smaller CSA of muscle fiber than their wild type littermates. In conclusion, acetate derived from the intestinal microbiome can contribute to maintaining skeletal muscle performance.

BACKGROUND: Data on concomitant mitral regurgitation (MR) in patients with severe aortic stenosis (AS) are scarce.MethodsâandâResults: We investigated the risk of concomitant MR in patients with severe AS in the CURRENT AS Registry-2 according to initial treatment strategy (transcatheter aortic valve implantation [TAVI], surgical aortic valve replacement [SAVR], or conservative). Among 3,365 patients with severe AS, 384 (11.4%) had moderate/severe MR (TAVI: n=126/1,148; SAVR: n=68/591; conservative: n=190/1,626). The cumulative 3-year incidence for death or heart failure (HF) hospitalization was significantly higher in the moderate/severe than no/mild MR group in the entire population (54.6% vs. 34.3%, respectively; P<0.001) and for each treatment strategy (TAVI: 45.0% vs. 31.8% [P=0.006]; SAVR: 31.9% vs. 18.7% [P<0.001]; conservative: 67.8% vs. 41.6% [P<0.001]). The higher adjusted risk of moderate/severe MR relative to no/mild MR for death or HF hospitalization was not significant in the entire population (hazard ratio [HR] 1.15; 95% confidence interval [CI] 0.95-1.39; P=0.15); however, the risk was significant in the SAVR (HR 1.92; 95% CI 1.04-3.56; P=0.04) and conservative (HR 1.30; 95% CI 1.02-1.67; P=0.04) groups, but not in the TAVI group (HR 1.03; 95% CI 0.70-1.52; P=0.86), despite no significant interaction (Pinteraction=0.37). CONCLUSIONS: Moderate/severe MR was associated with a higher risk for death or HF hospitalization in the initial SAVR and conservative strategies, while the association was less pronounced in the initial TAVI strategy.
RESUMEN
Statins were reported to have a potential effect of primary prevention of venous thromboembolism (VTE), although that of secondary prevention remains uncertain. To investigate the association between statins use and recurrent VTE in the current era. The COMMAND VTE Registry-2 is a multicenter registry enrolling 5,197 consecutive VTE patients among 31 centers in Japan between January 2015 and August 2020. We divided the entire cohort into 2 groups according to statins use at the time of discharge; the statins (N = 865) and no statins groups (N = 4332). The statins group was older (72.9 vs. 66.7 years, P < 0.001), and less often had active cancer (22.0% vs. 30.4%, P < 0.001). The cumulative incidence of discontinuation of anticoagulation was significantly lower in the statins group (60.3% vs. 52.6%, Log-rank P < 0.001). The cumulative 5-year incidence of recurrent VTE was significantly lower in the statins group (6.8% vs. 10.1%, Log-rank P = 0.01). Even after adjusting for the confounders, the lower risk of the statins group relative to the no statins group remained significant for recurrent VTE (HR 0.65, 95% CI 0.45-0.91, P = 0.01). The cumulative 5-year incidence of major bleeding was significantly lower in the statins group (12.2% vs. 14.1%, Log-rank P = 0.04), although, after adjusting for the confounders, the risk of the statins group relative to the no statins group turned to be insignificant (HR 0.77, 95% CI 0.59-1.00, P = 0.054). In this large real-world VTE registry, statins use was significantly associated with a lower risk for the recurrent VTE in the current era.

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.

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 to 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 (hazard ratio [HR]: 0.65, 95% confidence interval [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. CONCLUSION: 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.
RESUMEN
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.

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.

There were no data comparing the in-hospital outcomes after transcatheter aortic valve implantation (TAVI) with those after surgical aortic valve replacement (SAVR) in Japan. Among consecutive patients with severe AS between April 2018 and December 2020 in the CURRENT AS Registry-2, we identified 1714 patients who underwent aortic valve replacement (TAVI group: 1134 patients, and SAVR group: 580 patients). Patients in the TAVI group were much older (84.4 versus 73.6 years, P < 0.001) and more often had comorbidities than those in the SAVR group. In-hospital death rate was numerically lower in the TAVI group than in the SAVR group (0.6% versus 2.2%). After excluding patients with dialysis, in-hospital death rate was very low and comparable in the TAVI and SAVR groups (0.6% versus 0.8%). The rates of major bleeding and new-onset atrial fibrillation during index hospitalization were higher after SAVR than after TAVI (72% versus 20%, and 26% versus 4.6%, respectively), while the rate of pacemaker implantation was higher after TAVI than after SAVR (8.1% versus 2.4%). Regarding the echocardiographic data at discharge, the prevalence of patient-prosthesis mismatch was lower in the TAVI group than in the SAVR group (moderate: 9.0% versus 26%, and severe: 2.6% versus 4.8%). In this real-world data in Japan, TAVI compared with SAVR was chosen in much older patients with more comorbidities with severe AS. In-hospital death rate was numerically lower in the TAVI group than in the SAVR group.

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.

STUDY DESIGN: Multicenter prospective study. OBJECTIVE: Patients with central sensitization (CS) are reported to be at high risk of poor outcomes after spinal surgery. However, the influence of CS on surgical outcomes for lumbar disc herniation (LDH) remains unknown. This study aimed to examine the association between preoperative CS and surgical outcomes in LDH patients. METHODS: A total of 100 consecutive patients with LDH (mean age 51.2) who underwent lumbar surgery were included in this study. The extent of CS was evaluated using the central sensitization inventory (CSI), a screening tool for CS-related symptoms. The patients completed the following CSI and clinical outcome assessments (COAs) preoperatively and 12 months postoperatively: the Japanese Orthopaedic Association (JOA) score for back pain, JOA back pain evaluation questionnaire (JOABPEQ), and Oswestry Disability Index (ODI). The association between preoperative CSI scores, and preoperative and postoperative COAs was analyzed, and the postoperative changes were statistically evaluated. RESULTS: The preoperative CSI score significantly decreased 12 months postoperatively. Preoperative CSI scores showed a significant correlation with most COAs; however, a significant correlation was only identified in the social function and mental health domains of JOABPEC postoperatively. Higher preoperative CSI showed worse preoperative COAs; however, all COAs significantly improved regardless of CSI severity. There were no significant differences in any COAs among the CSI severity groups 12 months postoperatively. CONCLUSIONS: The results of this study showed that lumbar surgeries significantly improved the COAs regardless of preoperative severity of CS in patients with LDH.
RESUMEN
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.

PURPOSE: The impact of central sensitization (CS) on neurological symptoms and surgical outcomes in patients with lumbar spinal stenosis (LSS) remains unknown. This study aimed to investigate the influence of preoperative CS on the surgical outcomes of patients with LSS. METHODS: A total of 197 consecutive patients with LSS (mean age 69.3) who underwent posterior decompression surgery with or without fusion were included in this study. The participants completed the CS inventory (CSI) scores and the following clinical outcome assessments (COAs) preoperatively and 12 months postoperatively: the Japanese Orthopaedic Association (JOA) score for back pain, JOA back pain evaluation questionnaire, and Oswestry Disability Index (ODI). The association between preoperative CSI scores and preoperative and postoperative COAs was analyzed, and postoperative changes were statistically evaluated. RESULTS: The preoperative CSI score significantly decreased at 12 months postoperatively and was significantly correlated with all COAs preoperatively and 12 months postoperatively. Higher preoperative CSI showed worse postoperative COAs and inferior postoperative improvement rates in the JOA score, VAS score for neurological symptoms, and ODI. Multiple regression analysis demonstrated that preoperative CSI was significantly associated with postoperative low back pain (LBP), mental health, quality of life (QOL), and neurological symptoms at 12 months postoperatively. CONCLUSIONS: Preoperative CS evaluated by CSI had a significantly worse impact on surgical outcomes, including neurological symptoms, disability, and QOL, especially related to LBP and psychological factors. CSI can be used clinically as a patient-reported measure for predicting postoperative outcomes in patients with LSS.

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.

BACKGROUND: There has been no previous report evaluating the long impact of atrial fibrillation (AF) on the clinical outcomes stratified by the initial management [conservative or aortic valve replacement (AVR)] strategies of severe aortic stenosis (AS). METHODS: We analyzed 3815 patients with severe AS enrolled in the CURRENT AS registry. Patients with AF were defined as those having a history of AF when severe AS was found on the index echocardiography. The primary outcome measure was a composite of aortic valve-related death or hospitalization for heart failure. RESULTS: The cumulative 5-year incidence of the primary outcome measure was significantly higher in patients with AF than in those without AF (44.2â¯% versus 33.2â¯%, HR 1.54, 95â¯% CI 1.35-1.76). After adjusting for confounders, the risk of AF relative to no AF remained significant (HR 1.34, 95â¯% CI 1.16-1.56). The magnitude of excess adjusted risk of AF for the primary outcome measure was greater in the initial AVR stratum (Nâ¯=â¯1197, HR 1.95, 95â¯% CI 1.36-2.78) than in the conservative stratum (Nâ¯=â¯2618, HR 1.26, 95â¯% CI 1.08-1.47) with a significant interaction (pâ¯=â¯0.04). In patients with AF, there was a significant excess adjusted risk of paroxysmal AF (Nâ¯=â¯254) relative to chronic AF (Nâ¯=â¯528) for the primary outcome measure (HR 1.34, 95â¯% CI 1.01-1.78). CONCLUSIONS: In patients with severe AS, concomitant AF was independently associated with worse clinical outcomes regardless of the initial management strategies. In those patients with conservative strategy, paroxysmal AF is stronger risk factor than chronic AF.

STUDY DESIGN: This study is a retrospective review. OBJECTIVE: Central sensitization (CS) is a neurological phenomenon that involves hypersensitivity of the central nervous system. The central sensitization inventory (CSI) was developed as a screening tool to assess CS-related symptoms. The purpose of this study was to evaluate the association of preoperative CSI scores with patient-reported outcome measures (PROMs) including neurological symptoms for patients who underwent spine surgeries in a multicenter study. METHODS: A consecutive 673 patients who underwent spine surgery at 8 different institutions were included in this study. Preoperative CSI scores were assessed for all subjects. The participants completed the following PROMs: the Oswestry Disability Index (ODI), the Japanese Orthopaedic Association (JOA) back pain evaluation questionnaire (JOABPEQ) for lumbar spinal diseases, and the JOA cervical myelopathy evaluation questionnaire (JOACMEQ) for cervical spinal diseases. The association of CSI scores with PROMs was statistically evaluated. RESULTS: The average CSI score for the total subjects was 23.6 ± 13.5. The subjects with CS-related symptoms (CSI ≥ 40) were 13.2% (n = 89). The CSI score showed a significant and weak-to-moderate correlation with the PROMs including neurological symptoms that included all the domains of the JOACMEQ for cervical spinal diseases, and JOABPEQ and ODI for lumbar spinal diseases. Among these, psychological factors had the most influence on the correlation with CSI score. CONCLUSION: Central sensitization evaluated by the CSI is related to neurological symptoms and health-related quality of life in patients undergoing elective spine surgery.
