Changes in use and outcomes after fibrinogen concentrate insurance coverage for critical obstetrical hemorrhage: a nationwide questionnaire survey in Japan. Sci Rep 2024; 14:6711. [PMID: 38509152 PMCID: PMC10954662 DOI: 10.1038/s41598-024-57244-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2023] [Accepted: 03/15/2024] [Indexed: 03/22/2024] Open
Abstract
Fibrinogen concentrate (FC) for acquired hypofibrinogenemia associated with critical obstetrical hemorrhage (COH) was covered by public medical insurance in September 2021 in Japan. We aimed to investigate changes in the policy of FC use and its effect on COH after insurance coverage. A primary survey covering September 2020 to August 2021 and a secondary survey covering September 2021 to August 2022 were conducted at 428 higher-level medical facilities. We investigated the policy of FC use in transfusion strategy and the maternal outcomes in COH. Among the hospitals that responded to both surveys, the number of facilities that use FC increased from 51.5 (101/196) to 78.6% (154/196) (P < 0.0001). The number of COH cases treated using FC increased from 14.3 to 24.3% (P < 0.0001) and that transfused with ≥ 10 units of red blood cells (RBCs) decreased from 36.8 to 29.8% (P = 0.001). The incidence of pulmonary edema reduced by 3.7-2.0% (P = 0.021), and transfusion-induced allergy by 1.9-0.7% (P = 0.008). No changes were observed in the incidence of thromboembolism, arterial embolization, or hysterectomy. The increased use of FC after insurance coverage led to changes in the transfusion strategy, which may be associated with decreases in transfusions of RBCs, pulmonary edema, and transfusion-induced allergies.

Abstract
Introduction The prognosis of oral squamous cell carcinoma (OSCC) is often poor despite standard treatments. Additionally, no useful prognostic markers are available. Therefore, we aimed to investigate the relationship between serum Interleukin-6 (IL-6) levels and prognosis and explore its local and systemic effects in patients with OSCC. Methods Ninety-five new cases of OSCC were included, and the prognosis was compared between high and low serum IL-6 groups. The localization of IL-6 in OSCC tissues was examined. Furthermore, a comprehensive gene expression analysis was performed in OSCC tissues and compared between the two groups. Results A significant difference in overall survival and disease-free survival was observed. Furthermore, a substantial expression of IL-6 was localized in the stroma. Comprehensive gene expression analysis of tumor localization showed increased expression of genes related to oxidoreductase and lipid metabolism in the primary tissues of the group with high serum IL-6 levels. Regarding the correlation between blood tests and serum IL-6 levels, a strong positive correlation was observed between inflammatory responses and nutritional factors. Conclusion These results suggest that serum IL-6 may be a prognostic factor for metabolic abnormalities in patients with OSCC and that aggressive nutritional interventions may contribute to prognosis.

Designing the stripe-ordered cuprate phase diagram through uniaxial-stress. Proc Natl Acad Sci U S A 2024; 121:e2303423120.

Abstract
The ability to efficiently control charge and spin in the cuprate high-temperature superconductors is crucial for fundamental research and underpins technological development. Here, we explore the tunability of magnetism, superconductivity, and crystal structure in the stripe phase of the cuprate La[Formula: see text]Ba[Formula: see text]CuO[Formula: see text], with [Formula: see text] = 0.115 and 0.135, by employing temperature-dependent (down to 400 mK) muon-spin rotation and AC susceptibility, as well as X-ray scattering experiments under compressive uniaxial stress in the CuO[Formula: see text] plane. A sixfold increase of the three-dimensional (3D) superconducting critical temperature [Formula: see text] and a full recovery of the 3D phase coherence is observed in both samples with the application of extremely low uniaxial stress of [Formula: see text]0.1 GPa. This finding demonstrates the removal of the well-known 1/8-anomaly of cuprates by uniaxial stress. On the other hand, the spin-stripe order temperature as well as the magnetic fraction at 400 mK show only a modest decrease under stress. Moreover, the onset temperatures of 3D superconductivity and spin-stripe order are very similar in the large stress regime. However, strain produces an inhomogeneous suppression of the spin-stripe order at elevated temperatures. Namely, a substantial decrease of the magnetic volume fraction and a full suppression of the low-temperature tetragonal structure is found under stress, which is a necessary condition for the development of the 3D superconducting phase with optimal [Formula: see text]. Our results evidence a remarkable cooperation between the long-range static spin-stripe order and the underlying crystalline order with the three-dimensional fully coherent superconductivity. Overall, these results suggest that the stripe- and the SC order may have a common physical mechanism.

KRT13 and UPK1B for differential diagnosis between metastatic lung carcinoma from oral squamous cell carcinoma and lung squamous cell carcinoma. Sci Rep 2023; 13:22626. [PMID: 38114532 PMCID: PMC10730515 DOI: 10.1038/s41598-023-49545-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2023] [Accepted: 12/09/2023] [Indexed: 12/21/2023] Open
Abstract
Oral squamous cell carcinomas unusually show distant metastasis to the lung after primary treatment, which can be difficult to differentiate from primary squamous cell carcinoma of the lung. While the location and number of tumor nodules is helpful in diagnosing cases, differential diagnosis may be difficult even with histopathological examination. Therefore, we attempted to identify molecules that can facilitate accurate differential diagnosis. First, we performed a comprehensive gene expression analysis using microarray data for OSCC-LM and LSCC, and searched for genes showing significantly different expression levels. We then identified KRT13, UPK1B, and nuclear receptor subfamily 0, group B, member 1 (NR0B1) as genes that were significantly upregulated in LSCC and quantified the expression levels of these genes by real-time quantitative RT-PCR. The expression of KRT13 and UPK1B proteins were then examined by immunohistochemical staining. While OSCC-LM showed no KRT13 and UPK1B expression, some tumor cells of LSCC showed KRT13 and UPK1B expression in 10 of 12 cases (83.3%). All LSCC cases were positive for at least one of these markers. Thus, KRT13 and UPK1B might contribute in differentiating OSCC-LM from LSCC.

In situ uniaxial pressure cell for x-ray and neutron scattering experiments. THE REVIEW OF SCIENTIFIC INSTRUMENTS 2023; 94:013906. [PMID: 36725613 DOI: 10.1063/5.0114892] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/26/2022] [Accepted: 12/24/2022] [Indexed: 06/18/2023]
Abstract
We present an in situ uniaxial pressure device optimized for small angle x-ray and neutron scattering experiments at low-temperatures and high magnetic fields. A stepper motor generates force, which is transmitted to the sample via a rod with an integrated transducer that continuously monitors the force. The device has been designed to generate forces up to 200 N in both compressive and tensile configurations, and a feedback control allows operating the system in a continuous-pressure mode as the temperature is changed. The uniaxial pressure device can be used for various instruments and multiple cryostats through simple and exchangeable adapters. It is compatible with multiple sample holders, which can be easily changed depending on the sample properties and the desired experiment and allow rapid sample changes.

Abstract
Abstract
Background
In heart failure with reduced ejection fraction (HFrEF), drugs including angiotensin-converting enzyme inhibitors (ACEi)/ angiotensin receptor blockers (ARB), beta-blockers, and mineralocorticoid receptor antagonists (MRA) have been shown to have robust survival benefits. However, these guideline-recommended therapies remain underutilized in clinical practice. Frailty is common in HFrEF and may lead to underprescription of life-saving therapy.
Purpose
We aimed to investigate the association between physical frailty and the use of evidence-based pharmacological therapy for HFrEF, and the impact of this on prognosis
Methods
The FLAGSHIP study included patients hospitalized for acute HF and data on physical frailty were collected prospectively. Of the total 3,272 patients registered in the FLAGSHIP study, 1,041 HFrEF patients (70 years; 73% male) with left ventricular ejection fraction ≤40% were analyzed and were divided into 4 groups by severity of frailty: category I (n=371) [least frail], II (n=275), III (n=224), and IV (n=171) [most frail].
Results
An ACEi/ARB was prescribed in 76% of category I and 53% of category IV patients; for a beta-blocker these proportions were 94% and 76%, respectively; for an MRA they were 55% and 46%, respectively. The proportion of patients using receiving all 3 drugs decreased as frailty increased, with approximately twice the rate of use of triple therapy in category I patients (40.2%) compared to category IV patients (23.4%) [p<0.001] (Figure 1). In adjusted analyses, the severity of frailty was an independent predictor for non-use of an ACEi/ARB (Odds ratio (OR): 1.23, 95% CI: 1.05–1.43, per 1 category increase) and a beta-blocker (OR: 1.32, 95% CI: 1.06–1.64), but not an MRA (OR: 0.97, 95% CI: 0.84–1.12). Risk of the composite outcome of all-cause death or HF rehospitalization increased with decreasing use of treatment across frailty categories: category I-II (Hazard ratio (HR): 1.80, 95% CI: 1.08–2.98, in 0–1 drug with 3 drugs as reference) and III–IV (HR: 1.53, 95% CI: 1.01–2.32). The relationship between the number of HF drugs prescribed and the composite outcome did not differ across frailty categories (p-interaction=0.86). The HRs for all 12 groups, reflecting frailty categories and a number of HF drugs is depicted in Figure 2. The HRs for composite outcome increased with increasing frailty category and with decreasing number of drugs, with an almost 4-fold difference in risk between the least frail patients receiving all three evidence-based therapies and the most frail receiving only 0–1 drug.
Conclusions
Prescription of guideline-recommended therapy decreased as the severity of frailty increased in patients with HFrEF. Sub-optimal medical therapy was associated with a worse outcome and underprescription of guideline-recommended therapy may contribute to the poor prognosis associated with frailty. An effective strategy is needed to improve the medical treatment of frail patients with HFrEF.

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.

Differences in the prevention and incidence of maternal venous thromboembolism according to the type of institution in Japan in 2018: A sub-analysis of national questionnaire surveillance. J Obstet Gynaecol Res 2021; 48:663-672. [PMID: 34957638 DOI: 10.1111/jog.15100] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2021] [Revised: 10/20/2021] [Accepted: 11/03/2021] [Indexed: 11/26/2022]
Abstract
AIM To clarify the relation between institutions capacity to manage venous thromboembolism (VTE) and its incidence in pregnant women throughout Japan. METHODS Among the 2299 institutions that received the surveillance questionnaire, 666 (29.0%) responded, after which data from 295 961 women who gave birth at those institutions in 2018 were analyzed. Incidences and characteristics of antepartum and postpartum VTE in perinatal medical centers (PMCs), general hospital with obstetric facilities (GHs), and maternal clinic with beds (MCs) were then determined. RESULTS The frequencies at which routine antepartum and postpartum thromboprophylaxis for high-risk women and routine transport to the more advanced medical institutions upon antepartum and postpartum pulmonary thromboembolism (PE) onset were performed differed significantly according to types of institution (PMCs: 92.4%, 96.2%, 23.8%, and 21.2%; GHs: 76.5%, 80.6%, 58.8%, and 54.1%; MCs: 29.2%, 41.7%, 96.5%, and 96.2%, respectively). Among the 295 961 women analyzed, 243 (0.082%) developed VTE. Incidences of antepartum VTE differed significantly according to institution types (PMCs: 106.4, GHs: 51.6, and MCs: 11.6 per 100 000 women). PMCs and GHs had significantly higher incidences of postpartum VTE compared to MCs (43.3 and 26.6 vs. 10.7 per 100 000 women, respectively), although PMCs and GHs had similar incidences. Among the four women (1.4%) who died due to VTE, three and one developed a PE in a PMC and MC, respectively. CONCLUSIONS PMCs had higher incidences of VTE despite their more frequent performance of thromboprophylaxis. Several pregnant women with higher risk of VTE transported to PMCs.

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.

Mechanisms of instantaneous inactivation of SARS-CoV-2 by silicon nitride bioceramic. Mater Today Bio 2021; 12:100144.

Abstract
The hydrolytic processes occurring at the surface of silicon nitride (Si3N4) bioceramic have been indicated as a powerful pathway to instantaneous inactivation of SARS-CoV-2 virus. However, the virus inactivation mechanisms promoted by Si3N4 remain yet to be elucidated. In this study, we provide evidence of the instantaneous damage incurred on the SARS-CoV-2 virus upon contact with Si3N4. We also emphasize the safety characteristics of Si3N4 for mammalian cells. Contact between the virions and micrometric Si3N4 particles immediately targeted a variety of viral molecules by inducing post-translational oxidative modifications of S-containing amino acids, nitration of the tyrosine residue in the spike receptor binding domain, and oxidation of RNA purines to form formamidopyrimidine. This structural damage in turn led to a reshuffling of the protein secondary structure. These clear fingerprints of viral structure modifications were linked to inhibition of viral functionality and infectivity. This study validates the notion that Si3N4 bioceramic is a safe and effective antiviral compound; and a primary antiviral candidate to replace the toxic and allergenic compounds presently used in contact with the human body and in long-term environmental sanitation.

Background
Cardiac rehabilitation (CR) remains underutilised, despite its established clinical benefit. Assessments of personality traits may serve for patient-medical staff communication to promote CR implementation as they are determinants of health-related behavior. However, few studies have explored the potential effects of the Big Five personality traits on CR participation.
Purpose
This study aimed to examine the association between the Big Five personality traits and CR participation in patients with cardiovascular disease.
Methods
This longitudinal analysis included patients aged <80 years hospitalised for cardiovascular disease. We excluded patients aged ≥ 80 years because of the increased prevalence of the need of assistance for outdoor walking, resulting in non-participation in CR. The Big Five personality traits (conscientiousness, neuroticism, openness, extraversion, agreeableness) of each patient were evaluated using the Japanese version of Ten-Item Personality Inventory at discharge (references: 1, 2). Each patient was also asked to answer a self-administered questionnaire related to outpatient CR. The questionnaire included the will to participate in outpatient CR after discharge (yes or no) and the reasons for non-participation in CR. We examined the frequency of CR attendance for each patient for three months after discharge from medical records. According to the participation frequency, patients were stratified into non-participation, participation, and dropout groups. The participation group was defined as at least one CR session a month within three months after discharge. Patients who did not continue CR for three months were considered dropouts. We examined the relationship of each personality trait with non-participation in CR and dropout within three months using logistic regression analysis.
Results
A total of 139 patients hospitalised for cardiovascular disease were analysed (the mean age: 67.2 ± 9.8 years, men: 71.9%). Of 49 patients who initiated the outpatient CR after discharge, 26 patients continued CR for three months, and 23 patients dropped out. The results of the logistic regression analysis are shown in Figure 1. After adjusted for age, gender, and heart failure, high conscientiousness was associated with non-participation in CR (odds ratio [OR] 1.35, per 1 point; 95% confidence interval (CI) 1.00-1.87). The primary reason for non-participation among patients with high conscientiousness was a lack of motivation. Conversely, low conscientiousness (OR 0.56; 95% CI 0.35-0.90) and high openness (OR 2.19; 95% CI 1.27-3.78) were predictors of dropout within three months after discharge.
Conclusion
The results of this study imply that the Big Five assessment serves for the health communication to improve CR participation. In particular, high conscientious was associated with non-participation in CR due to a lack of motivation, and patients with low conscientiousness and high openness tended to dropout.

Background
Cognitive decline is common among older patients with cardiovascular disease and can decrease their self-management abilities. Therefore, early detection of cognitive decline is clinically important, as it can help guide effective home-based care measures, including education of family members and deployment of healthcare resources. However, the standard instruments for identifying mild cognitive impairment (MCI) are not always feasible in clinical practice.
Purpose
This study evaluated whether MCI could be detected using the Japanese version of the Rapid Dementia Screening Test (RDST-J), which is a simple screening tool for identifying cognitive decline.
Methods
This cross-sectional study included patients who were ≥ 65 years old and hospitalised because of cardiovascular disease. Patients with a pre-hospitalisation diagnosis of dementia were excluded. Each patient’s cognitive function had been measured at discharge using the RDST-J and the Japanese version of the Montreal Cognitive Assessment (MoCA-J), which is a standard tool for MCI screening. The RDST-J includes a number transcoding task and a supermarket task, and can be completed in 3 min (range: 0–12 points). The MoCA-J assesses nine domains of cognition and requires 10–15 min to complete (range: 0–30 points). The correlation between the two scores was evaluated using Spearman’s rank correlation coefficient. Receiver operating characteristic (ROC) analysis was also conducted to evaluate whether the RDST-J could identify MCI, which was defined as a MoCA-J score of ≤ 25 points.
Results
The study included 78 patients (the mean age: 77.2 ± 8.9 years, men: 56.4%). Based on a MoCA-J score of ≤ 25 points, MCI was identified in 73.1% (n = 57) of the patients. The RDST-J and MoCA-J scores were strongly correlated (r = 0.835, p <0.001). The ROC analysis revealed that an RDST-J score of ≤ 9 points provided 75.4% sensitivity and 95.2% specificity for identifying MCI, with an area under the curve of 0.899 (95% confidence interval: 0.835–0.964, Figure 1). The same cut-off value was identified when excluding patients with a high probability of dementia (RDST-J score of ≤ 4 points).
Conclusions
The RDST-J is a simple instrument and its score was highly correlated with the standard test for identifying MCI in older patients with cardiovascular disease. Our results suggest that the RDST-J may be useful for routine cognitive assessments in clinical practice. Longitudinal studies are needed to evaluate whether the RDST-J scores respond to changes in cognitive status, as well as whether this tool can be used to predict adverse health outcomes after discharge.

Introduction
Long-term care insurance (LTCI) has a key role in the disease management of older patients in Japan. However, clinical benefit of coordinating LTCI service during hospitalization has not been examined in patients with heart failure (HF).
Purpose
We aimed to examine the association between the coordination of LTCI service and adverse outcome after discharge in Japanese older patients with HF.
Methods
The inclusion criteria of this retrospective cohort study were patients aged ≥ 65 years hospitalised for HF who used any LTCI services after discharge. In Japan, people aged ≥ 65 who satisfy the eligibility criteria are eligible to receive LTCI services. Questionnaires regarding daily life and activities are used to assess eligibility and create the 7 certification levels: support required 1 or 2, and care levels 1 (least disabled) to 5 (most disabled). In this study, patients were divided into 1) patients without any change in LTCI service during hospitalisation (Group N), 2) patients with coordination of LTCI services during hospitalization (Group C), 3) patients who newly initiated LTCI service after discharge (Group I). The primary outcome was a composite of HF rehospitalisation and all-cause mortality. Survival rate was compared using Kaplan-Meier curve analysis and log-rank test. Multivariate analysis was conducted using Cox proportional-hazards model adjusted for propensity score calculated based on age, gender, brain natriuretic peptide, β-blocker, angiotensin converting enzyme inhibitor /angiotensin II receptor blocker, need of any walking device or assistance at discharge, living alone, LTCI level.
Results
A total of 135 older patients were included (mean age 84 years, men 46%). During the median follow-up of 580 days, 43 events occurred. The number of patients for each group was as following: Group N, n = 91; Group C, n = 20; Group I, n = 24. The survival rates were significantly different among the three groups (log-rank test p = 0.039 , Figure 1). In Cox proportional-hazards model with Group N as a reference, Group C was associated with reduced risk of the study outcome (hazard ratio 0.22, 95% confidence interval 0.05-0.91, p = 0.036). Group I also showed lower event rate but not statistically significant (hazard ratio 0.81, 95% confidence interval 0.20-0.30, p = 0.756). All the patients in Group C used visiting nurse service, whereas the implementation rates were 12.1% and 37.5% in Group N and Group I, respectively. Implementation rate of visiting rehabilitation was higher in Group C (20.0%) compared to Group N (1.1%) and Group I (4.2).
Conclusions
Patients with coordination of LTCI service during HF hospitalization showed reduced risk of adverse outcome after discharge, implying the clinical benefits of utilization of LTCI service. Further large-scale studies are needed to examine the optimal utilization of tailor-made LTCI service according to the patient’s condition.

A retrospective cohort study using a national surveillance questionnaire to investigate the characteristics of maternal venous thromboembolism in Japan in 2018. BMC Pregnancy Childbirth 2021; 21:514. [PMID: 34273959 PMCID: PMC8286571 DOI: 10.1186/s12884-021-03993-1] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2020] [Accepted: 07/02/2021] [Indexed: 11/20/2022] Open
Abstract
BACKGROUND In Japan, the numbers of deliveries by women of older maternal age and women with overweight or obesity have recently increased. Since 2008, the guidelines and practices to prevent the maternal venous thromboembolism (VTE) have been recommended antepartum and postpartum thromboprophylaxis for each risk level of VTE. This study aimed to clarify the incidence and characteristics (type of VTE and thromboprophylaxis) of VTE in pregnant women in Japan to reduce the rate of mortality from VTE METHODS: Of 2299 institutions sent the surveillance questionnaire, 666 (29.0%) responded, and data from 295,961 women who gave birth in those institutions in 2018 were analyzed. We calculated the incidence and characteristics of VTE before and after the deliveries. RESULTS At the responding institutions, 243 women (0.082%) had VTE in 2018. In 2018, deep vein thrombosis was significantly more common (0.0053%) than pulmonary thromboembolism (0.0019%; p < 0.0001). The incidence of antepartum VTE (0.0055%) was significantly higher than that of postpartum VTE (0.0026%; p < 0.0001). The incidence of VTE after cesarean Sect. (0.0074%) was significantly higher than that after vaginal delivery (0.0012%; p < 0.0001). Of the women with VTE, 4 (1.6%) died. CONCLUSIONS Among the women thought to have a low risk of VTE during the antepartum period, and especially women who had a vaginal delivery, the actual incidence of VTE might have increased in Japan.

Capacity of Japanese institutions to manage obstetrical disseminated intravascular coagulation in 2018: A national surveillance questionnaire and retrospective cohort study. J Obstet Gynaecol Res 2021; 47:3159-3170. [PMID: 34254400 DOI: 10.1111/jog.14875] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2021] [Revised: 04/17/2021] [Accepted: 05/03/2021] [Indexed: 11/30/2022]
Abstract
AIM To investigate the management of obstetrical disseminated intravascular coagulation (DIC) in Japan. METHODS We sent a surveillance questionnaire to 2299 institutions to collect details about the deliveries they performed in 2018. We investigated differences in the management of obstetrical DIC among three types of institutions: perinatal medical centers (PMCs), general hospitals with obstetrical facilities (GHs), and maternal clinics with beds (MCs). RESULTS We received responses from 703 institutions (30.6% of the total mailed) with results of 306 799 women who gave birth in 2018. In Japan, the potential to treat postpartum hemorrhage and obstetrical DIC was high in the PMC group, moderate in the GH group, and low in the MC group. The incidence of obstetrical DIC in the PMC group (0.44%) was significantly higher than that in the GH (0.21%) and MC (0.06%) groups. The mortality of women with obstetrical DIC in PMCs (1.3%) was similar to that in GHs (0.6%) and MCs (0.0%). The percentages of PMCs that always or sometimes transfused fresh frozen plasma or fibrinogen concentrates (100% and 42.2%, respectively) were significantly higher than those in the GH (88.2% and 29.5%, respectively) and MC groups (29.4% and 5.3%, respectively). Furthermore, institutions whose internal protocols mandated that replacement therapy be always administered in women with obstetrical DIC scores of ≥8 had similar protocols to those for women with fibrinogen levels of ≤1.5 g/L. CONCLUSIONS The capacity to provide therapy for postpartum hemorrhage and obstetrical DIC varied widely among the three groups of institutions.

Abstract
OBJECTIVE To determine the risk factors associated with the preterm premature rupture of membranes (p-PROM). MATERIALS AND METHODS This retrospective cross-sectional study assessed 110 p-PROM cases from among 6642 deliveries at a Japanese perinatal medical center, from June 2016 to September 2018. The control group comprised 220 term PROM (t-PROM) cases. We excluded cases with artificial PROM or rupture of membranes after labor, those with multiple pregnancies, those with p-PROM at 36 weeks and those with t-PROM at 37 weeks. In order to compare p-PROM with t-PROM, univariate and multivariate analysis were performed using several clinical factors at the time of PROM onset. RESULTS The p-PROM group included 110 cases with 14-35 weeks PROM, and the t-PROM group included 220 cases with 38-41 weeks PROM. Eleven factors were identified as significant factors on the univariate analysis. A history of cervical conization (OR 37.5, 95% CI: 2.31-607.1), cervical length <25 mm at 28 weeks (OR 9.31, 95% CI: 1.76-49.3), negative Lactobacillus (OR 4.01, 95% CI: 1.18-13.7), and bleeding during the second trimester (OR 3.35, 95% CI: 1.18-9.53) were identified as significant factors by the multivariate analysis. Based on the risk factors identified during the multivariate analysis, we divided the 330 cases in the following three groups: 0 group (n = 244), 1 group (n = 60), and 2-4 group (n = 26). The ratio of p-PROM:t-PROM was calculated and compared for each group. The ratios were 21% (0 group), 57% (1 group), and 100% (2-4 group), indicating statistically significant differences between the groups (p < 0.001). CONCLUSION We found that the following four factors were associated with p-PROM: history of cervical conization, cervical length <25 mm at 28 weeks, negative Lactobacillus, and bleeding during the second trimester. Our results suggest that we can identify patients who are at increased risk for p-PROM, based on these factors. Further research is necessary to determine the optimal treatment approach for these patients to prevent p-PROM.

Clinical guidance for peripartum management of patients with hereditary thrombophilia. J Obstet Gynaecol Res 2021; 47:3008-3033. [PMID: 34169611 DOI: 10.1111/jog.14879] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2021] [Revised: 05/13/2021] [Accepted: 05/29/2021] [Indexed: 12/24/2022]
Abstract
Hereditary thrombophilia is a condition in which individuals are susceptible to the formation of thrombi due to a hereditary deficiency in anticoagulant factors, antithrombin (AT), protein C (PC), or protein S (PS). Many Japanese thrombophilia patients have PS deficiency, especially PS p.K196E (also called as PS Tokushima), which is exclusive to the Japanese population, and thrombosis sometimes occurs during pregnancy. At present, no management guidelines for pregnancy and delivery in thrombophilia patients have been developed. The Study Group for Hereditary Thrombophilia, one of the research groups of blood coagulation abnormalities in the Research Program on Rare and Intractable Diseases supported with the Research Grants of the Ministry of Health, Labour and Welfare Science, has therefore developed this clinical guidance to provide healthcare workers with necessary information on safe pregnancy, parturition and neonatal management, adopting a format of responses to seven clinical questions (CQ). At the end of each answer, the corresponding Recommendation Level (A, B, C) is indicated.

Abstract
INTRODUCTION Preeclampsia is a leading cause of maternal and perinatal morbidity and mortality. Several studies have demonstrated the beneficial effects of antithrombin replacement in patients with preeclampsia. Here, we describe the study protocol of KOUNO-TORI (KW-3357 randOmized, mUlti-center, double-bliNd, placebO-controlled phase 3 sTudy in patients with early Onset pReeclampsIa) to evaluate recombinant human antithrombin gamma (rhAT-gamma) for the treatment of early-onset severe de novo preeclampsia. MATERIAL AND METHODS Patients with early-onset severe de novo preeclampsia who are ≥24 to <32 weeks pregnant at the time of registration and have an antithrombin activity of ≤100% at screening are included. The target population is selected based on a reanalysis of the data of a previous plasma-derived antithrombin phase 3 study. Primary endpoint is the prolongation of pregnancy from the initiation of rhAT-gamma treatment to the pregnancy termination. Secondary endpoints include gestational age in terms of achievement of 32- and 34-weeks'gestation, and gestational age in terms of achievement of 28 weeks' gestation for patients enrolled at <28 weeks' gestation. Maternal, fetal, and neonatal outcomes will be assessed. DISCUSSION As we have selected a specifically defined target population based on reanalysis of data of a previous plasma-derived antithrombin phase 3 study, the results of our study are expected to provide efficacy and safety data concerning rhAT-gamma treatment in Japanese patients. This study could help identify an effective novel treatment for such patients with early-onset severe preeclampsia for whom appropriate treatment is unavailable.

Easy clinical predictor for low BCAA to tyrosine ratio in chronic liver disease patients with hepatocellular carcinoma: Usefulness of ALBI score as nutritional prognostic marker. Cancer Med 2021; 10:3584-3592.

Abstract
Background/Aim Low branched‐chain amino acid (BCAA) to tyrosine ratio (BTR) is known as an indicator of amino acid imbalance. We elucidated usefulness of newly developed albumin–bilirubin (ALBI) score as alternative methods of BTR in patients with naïve hepatocellular carcinoma (HCC) retrospectively. Materials/Methods In 842 patients with HCC and without BCAA supplementation (71 years, male 614, Child‐Pugh A:B:C = 689:116:37), relationships among BTR and clinical features were evaluated. Of those, 438 patients, with Milan criteria HCC, treated curatively were divided into the high‐BTR (>4.4) (n = 293) and low‐BTR (≤4.4) (n = 145) groups. The prognostic value of BTR was evaluated using inverse probability weighting (IPW) with propensity score. Results The low‐BTR group showed worse prognosis than the other (3‐, 5‐, 10‐year overall survival rates: 88.9% vs. 86.3%/70.5% vs. 78.1%/38.1% vs. 52.3%, respectively; p < 0.001). Multivariate Cox‐hazard analysis adjusted for IPW showed elderly (≥65 years) HR 2.314, p = 0.001), female gender (HR 0.422, p < 0.001), ECOG PS ≥2 (HR 3.032, p = 0.002), low platelet count (HR 1.757, p = 0.010), and low BTR (≤4.4) (HR 1.852, p = 0.005) to be significant prognostic factors. Both serum albumin level (r = 0.370, p < 0.001) and ALBI score (r = −0.389, p < 0.001) showed a significant relationship with BTR. Child‐Pugh class B, modified ALBI grade (mALBI) 2a, and mALBI 2b predictive values for BTR were 3.589, 4.509, and 4.155 (AUC range: 0.735–0.770), respectively, while the predictive value of ALBI score for low‐BTR (≤4.4) was −2.588 (AUC 0.790). Conclusion ALBI score −2.588 was a predictor for low‐BTR (≤4.4), which was prognostic factors for early HCC patients, and at least patients with mALBI 2b might have an amino acid imbalance.

Effect of hypofibrinogenemia on obstetrical disseminated intravascular coagulation in Japan in 2018: a multicenter retrospective cohort study. Int J Hematol 2021; 114:18-34.

Abstract
Japanese obstetrical hemorrhage recommendations state that not only pregnant women with an obstetrical disseminated intravascular coagulation (DIC) score ≥ 8 points but also those with fibrinogen levels ≤ 1.5 g/L have a high risk of maternal death and warrant blood transfusion. Our aim was to demonstrate the potential of fibrinogen levels ≤ 1.5 g/L as predictors of a Japanese obstetrical DIC score of ≥ 8. We included 595 participants with blood loss ≥ 1000 mL during vaginal delivery or ≥ 2000 mL during cesarean delivery. The frequency and volume of red blood cell (RBC), fresh-frozen plasma, platelet concentrate (PC), and fibrinogen administration in women with a DIC score of ≥ 8 and fibrinogen levels of ≤ 1.5 g/L were significantly higher than controls (P < 0.0001). Multivariate analysis demonstrated that a score of ≥ 3 was associated with RBC or fibrinogen administration and a score of ≥ 5 was associated with PC transfusion. Fibrinogen levels ≤ 1.89 g/L and ≤ 2.44 g/L were associated with PC transfusion and fibrinogen administration, respectively. Fibrinogen levels ≤ 1.5 g/L may have similar potential to a DIC score of ≥ 8 points for detecting obstetrical DIC in Japan.

Abstract
This study aimed to examine the incidence of hypertensive disorders of pregnancy (HDP) among Japanese women with oocyte donation pregnancy (ODP) aged 40 years or older and estimate whether the women with ODP were more likely to develop HDP than those with autologous oocyte pregnancy (AOP) and spontaneous pregnancy (SP). In our study (N = 1361), the proportions of women who developed HDP were 20.5%, 12.8%, and 7.6% for ODP, AOP, and SP, respectively. After adjustment of covariables, the women with ODP were more likely to develop HDP than those with AOP or SP.

Abstract
Patients with congenital protein S (PS) deficiency show a hereditary predisposition for thrombosis, and PS deficiency is prevalent among Japanese populations. Diagnosis is based on symptoms of thrombosis and reduced PS activity. Three reagents that use different measurement principles for determining PS activity are available in Japan. This study aimed to confirm the possibility of harmonization of these three reagents to establish a universal standard for PS activity in Japanese populations. Commercial normal plasma and plasma samples obtained from healthy individuals and healthy pregnant women were tested at three facilities using three reagents for measuring PS: STA-Staclot Protein S (STA-PS), HemosIL Protein S (Clotting) (IL-PS), and a total PS assay (SNT-PS). The within-run precision of each reagent was good, as each had a coefficient of variation of ≤ 3.8%. The dilution linearity for each reagent was also good. The correlation coefficient was 0.94 for STA-PS vs. IL-PS, 0.93 for SNT-PS vs. STA-PS, and 0.90 for SNT-PS vs. IL-PS, indicating a good correlation. Although the three reagents available in Japan for measuring PS activity use different measurement methods, each showed good performance, and large differences were not observed between the obtained values. Harmonization among them appears possible.

Abstract
Objective This study evaluated cases of pruritus, which is known to be associated with sleep disorder, in chronic liver disease (CLD) patients. Methods Questionnaires were given to 339 enrolled CLD outpatients in winter (November 2019 to March 2020) and again in summer (April to October 2020) (median interval: 104 days). Relative changes in symptoms shown by a visual analogue scale (VAS) and Kawashima's pruritus score between winter and summer were evaluated in Study 1 (n=199), while Study 2 examined the clinical features of patients with sleep disorder based on the results of the second questionnaire (n=235, median age 70 years old; 141 men, liver cirrhosis 37%). Results Study 1. There was a significant relationship in VAS between daytime and nighttime for each season, as well as between winter and summer for each time period (p<0.001). A comparison of Kawashima's pruritus scores for the daytime and nighttime showed no significant seasonal differences (p=0.436 and 0.828, respectively). When Kawashima's score increased, so did the average VAS for both daytime (0:1:2:3:4=0.4±0.2:1.4±0.9:3.0±1.8:5.9±2.1:6.2±2.3) and nighttime (0:1:2:3:4=0.3±0.1:1.4±1.5:3.5±2.3:6.7±2.6:6.9±1.8) (p<0.001 for both). Study 2. Twenty subjects (8.5%) complained of sleep disorder. An elevated FIB-4 index (≥3.07) showed a good predictive value for sleep disorder (p<0.01). The cut-off for the daytime and nighttime VAS values for existing sleep disorder were 1.6 [area under the curve (AUC) 0.901] and 3.4 (AUC 0.931). The respective sensitivity, specificity, and positive and negative predictive values for sleep disorder based on Kawashima's score (≥2) were 0.85, 0.28, 0.10, and 0.95 for the daytime and 1.00, 0.29, 0.12, and 1.00 for the nighttime. Conclusion Intervention against pruritus is recommended in CLD patients with a high Kawashima's score (≥2) in any season, especially with an elevated FIB-4 index.

Abstract
Abstract
Background
Weight loss (WL) has been considered as a prognostic factor in heart failure with reduced ejection fraction (HFrEF). However, the prognosis and associated factors of WL in heart failure with preserved ejection fraction (HFpEF) have remained unclear.
Purpose
This study aimed to examine the prevalence, prognosis, and clinical characteristics of worse prognosis based on the identified WL after discharge in HFpEF.
Methods
The study was conducted as a part of a multicenter cohort study (Flagship). The cohort study enrolled ambulatory HF who hospitalized due to acute HF or exacerbation of chronic HF. Patients with severe cognitive, psychological disorders or readmitted within 6-month after discharge were excluded in the study. WL was defined as ≥5% weight loss in 6-month after discharge and HFpEF was defined as left ventricular ejection fraction (LVEF) ≥50% at discharge. Age, gender, etiology, prior HF hospitalization, New York Heart Association (NYHA) class, brain natriuretic peptide (BNP) or N-terminal-proBNP (NT-proBNP), anemia (hemoglobin; male <13g/dL, female <12g/dL), serum albumin, Geriatric Depression Scale, hand grip strength and comorbidities were collected at discharge. Patients were stratified according to their body mass index (BMI) at discharge as non-obese (BMI <25) or obese (BMI ≥25). We analyzed the association between WL and HF rehospitalization from 6 month to 2 years after discharge using Kaplan-Meier curve analysis and Cox regression analysis adjusted for age and gender, and clinical characteristics associated to worse prognosis in WL using logistic regression analysis adjusted for potential confounders in HFpEF.
Results
A total of 619 patients with HFpEF were included in the analysis. The prevalence of WL was 12.9% in 482 non-obese and 15.3% in 137 obese patients. During 2 years, 72 patients were readmitted for HF (non-obese: 48, obese: 24). WL in non-obese independently associated with poor prognosis (hazard ratio: 2.2: 95% confidence interval: 1.13–4.25) after adjustment for age and sex, while WL in obese patients did not. Logistic regression analysis chose age (odds ratio 1.02 per 1 year; 1.00–1.05), anemia (2.14; 1.32–3.48), and BNP ≥200pg/mL or NT-proBNP ≥900pg/mL (1.83; 1.18–2.86) as independent associated factors for worse prognosis of WL in non-obese patients.
Conclusion
In HFpEF, WL in early after discharge in non-obese elderly patients may be a prognostic indicator for HF rehospitalization. HF management including WL prevention along with controlling anemia is likely to improve prognosis in this population.

Abstract
Background
Long-term prognosis after percutaneous coronary intervention (PCI), particularly non-target region stenosis, has not been well improved. Therefore, lifestyle modification should be considered along with medication to prevent the progression of coronary atherosclerosis. Particularly, the promotion of physical activity (PA) is recommended as a core intervention for secondary prevention because of its direct effects on coronary risk factors. However, the factors related to PA after PCI have not been fully investigated.
Purpose
To explore predictors of PA after discharge in patients underwent PCI.
Methods
We conducted a multicenter prospective cohort study. Participants were patients aged <75 years who underwent PCI. The main outcome was PA {step counts (SC) and a time of moderate-to-vigorous physical activity (MVPA)} measured for 7 consecutive days using an accelerometer at 3-month post discharge. We collected demographic data, comorbidities, medical history, laboratory data, and medications from medical record. In addition, severity of chest pain at the onset, physician's explanation regarding long-term prognosis, exercise environments, social support, work, lifestyle except exercise, self-efficacy for walking, difficulty in daily activities and depression were evaluated using questionnaires at discharge and 1-month post-discharge. The study participants were divided into two groups based on the median SC and MVPA at 3-month, and clinical characteristics were compared between the groups using χ2test or Mann Whitney U test. Then, multiple logistic regression analysis adjusted for age, gender, and diagnosis {stable angina or acute coronary syndrome (ACS)} was conducted with 3-month PA as dependent variable. Independent variables were those with a p<0.2 in the univariate analysis. In addition, the area under the curve (AUC) was calculated by receiver operating characteristic analysis to assess predictive accuracy of the regression model.
Results
We enrolled 313 patients [median age: 63 {inter-quartile range (IQR):56–67} years, women: 13.1%, ACS: 16.4%]. The median of SC and MVPA at 3-month were 6902 steps (IQR:5078–9095) and 16.2 min (IQR: 8.6–28.9), respectively. Predictors of SC at 3-month ≥the median were SC at 1-month (odds ratio 1.78, per 1000 steps/day; 95% confidence interval 1.51–2.09), hemoglobin (1.43, per 1g/dl; 1.10–1.86), body mass index (BMI) (0.87, per 1kg/m2; 0.82–0.99), use of β-blocker (0.49, 0.25–0.95), and self-efficacy for walking (1.06, per 1 point; 1.00–1.11). Predictors of MVPA ≥the median were MVPA at 1-month (5.66, per 10 minutes/day; 3.63–8.84), hemoglobin (1.57, per 1g/dl; 1.19–2.06), and BMI (0.85, per 1kg/m2; 0.76–0.94). The AUC of the regression model for SC and MVPA were 0.87 and 0.89, respectively.
Conclusion
PA after PCI could be predicted by modifiable factors with good predictive accuracy. The findings of this study suggest the possibility to develop tailored PA promotion program.

Abstract
Abstract
Introduction
Extracellular signal-regulated kinase (ERK) modulates differentiation and maturation of adipocyte and the hypertrophy and differentiation of adipocytes affected the vascular diseases in obese. Changes in characters of adipocytes could develope the oxidative stress and inflammations. Moreover, changes in perivascular adipose tissue (PVAT) could modulate vascular tonus in obesity. However, the role of adipose ERK2 in endothelial function and characters of PVAT in obese in vivo had not been clarified, yet.
Purpose
This study aims to elucidate the role of the adipose ERK2 in endothelial-dependent relaxation (EDR) in mice model of obesity. The role of PVAT in EDR was also assessed.
Methods and results
We created adipose-specific ERK2 knock out mice (AE2KO) by crossing fatty acid binding protein 4 Cre and ERK2 flox mice and fed them with normal diet (ND) or high fat/ high sucrose diet (HFHSD) for 24 weeks. AE2KO fed with HFHSD gained more weight and revealed the heterogeneity in sizes of adipocyte in subcutaneous fat (SF). Furthermore, the mRNA levels of lipoprotein lipase, hormone-sensitive lipase, and peroxisome proliferator-activated receptor γ, which was the master genes of adipocyte differentiation, were markedly down-regulated in SF. PVAT in AE2KO with HFHSD was markedly enlarged and the mRNA expression of inflammatory adipocytokines, such as IL-1β and leptin were up-regulated. Next, we assessed EDR by acetylcholine (ACh) -induced relaxation in aortic rings with or without PVAT. EDR without PVAT was modestly decreased in AE2KO with HFHSD compared with wild type mice (WT) with HFHSD. Aortic rings with PVAT increased EDR in WT with ND. PVAT modestly decreased EDR in WT with HFHSD and mostly eliminated EDR in AE2KO with HFHSD. To assess the contraction factors released from PVAT, the solutions incubated with PVAT (SIP) were transferred to the normal aortic rings. SIP from WT with HFHSD mildly increased vascular tone and SIP from AE2KO with HFHSD further increased it. Tempol, which was superoxide scavenger, restored endothelial dysfunction with PVAT and suppressed the contraction with SIP from AE2KO with HFHSD. Fluorescence intensity of dihydroethidium stain of aorta and PVAT, which indicated that aortic and adipose superoxide production were elevated in AE2KO with HFHSD, which were mostly eliminated with tempol.
Conclusions
Adipose ERK2 selectively modulated differentiation in SF, suppressed the aortic oxidative stress and protected from endothelial dysfunction in obese. Moreover, adipose ERK2 suppressed the hypertrophy, inflammation, and oxidative stress of PVAT in obese. The oxidative stress with the inflammation in PVAT released vasoconstriction factors, which contributed to endothelial dysfunction in obese mice.

Abstract
Aim The aim of this study was to examine regret over the timing of the childbearing decision and reasons for its delay. Design A cross-sectional study. Methods This cross-sectional study included 219 women and 169 men referred to fertility facilities in Japan from July-December 2018. Participants completed a questionnaire on the reasons for their delay in childbearing decision and the degree of regret regarding their decision. Multiple linear regression was used to analyse the association between degree of regret and the reasons for the delay. Results The top three reasons for the delay in childbearing decision in women were "Establishing the relationship," "Health problems," and "Financial security." The top three reasons in men were "Establishing the relationship," "Financial security," and "Lack of fertility knowledge." Multiple linear regression showed that lack of fertility knowledge was associated with regret over the timing of childbearing decisions in women and men.

Using Uniaxial Stress to Probe the Relationship between Competing Superconducting States in a Cuprate with Spin-stripe Order. PHYSICAL REVIEW LETTERS 2020; 125:097005.

Abstract
We report muon spin rotation and magnetic susceptibility experiments on in-plane stress effects on the static spin-stripe order and superconductivity in the cuprate system La_{2-x}Ba_{x}CuO_{4} with x=0.115. An extremely low uniaxial stress of ∼0.1 GPa induces a substantial decrease in the magnetic volume fraction and a dramatic rise in the onset of 3D superconductivity, from ∼10 to 32 K; however, the onset of at-least-2D superconductivity is much less sensitive to stress. These results show not only that large-volume-fraction spin-stripe order is anticorrelated with 3D superconducting coherence but also that these states are energetically very finely balanced. Moreover, the onset temperatures of 3D superconductivity and spin-stripe order are very similar in the large stress regime. These results strongly suggest a similar pairing mechanism for spin-stripe order and the spatially modulated 2D and uniform 3D superconducting orders, imposing an important constraint on theoretical models.

Regret over the delay in childbearing decision negatively associates with life satisfaction among Japanese women and men seeking fertility treatment: a cross-sectional study. BMC Public Health 2020; 20:886. [PMID: 32513145 PMCID: PMC7282077 DOI: 10.1186/s12889-020-09025-5] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2019] [Accepted: 06/01/2020] [Indexed: 01/07/2023] Open
Abstract
BACKGROUND Currently, in developed countries, increasing numbers of women and men are delaying childbearing but begin seeking fertility treatment later in life. Some women undergoing infertility treatment develop negative feelings such as depression associated with low life satisfaction and regret over the delay in childbearing. We therefore examine the association of life satisfaction with regret over the delay in childbearing decision and infertility-related factors among Japanese women and men seeking fertility treatment. METHODS This cross-sectional study included 253 women and 196 men referred to fertility facilities in Japan from July to December 2018. Participants completed a questionnaire on life satisfaction, regret over the delay in childbearing decision, infertility-related factors and sociodemographic characteristics. Life satisfaction was measured using the Satisfaction with Life Scale (SWLS), and the degree of regret over delay in childbearing decision was measured on a 7-point Likert scale. Multiple linear regressions, conducted separately by sex, were used to analyze the association of life satisfaction with regret over the delay in childbearing decision and infertility-related factors. RESULTS Of the 253 women and 196 men, 102 (40.3%) women and 43 (21.9%) men answered "strongly agree" regarding their regret over the delay in childbearing decision. Among women, life satisfaction was negatively associated with regret (β = - 0.155, 95% CI [- 0.938, - 0.093], p = 0.017), use of assisted reproduction technology (ART) (β = - 0.135, 95% CI [- 2.977, - 0.020], p = 0.047). In contrast, previous live birth was positively associated with life satisfaction (β = 0.134, 95% CI [0.122, 3.739], p = 0.037). In men, we found no significant association of life satisfaction with regret over the delay in childbearing decision and infertility-related factors. CONCLUSIONS Regret over the delay in childbearing decision is negatively associated with life satisfaction among Japanese women seeking fertility treatment. It may be important for women to make better informed decision regarding the timing of childbearing to not regret later in life. Health professionals should address regret over the delay in childbearing decision during fertility treatment and explore ways to spread information on fertility awareness.

Abstract
Abstract
Background
Cavotricuspid isthmus (CTI) ablation for atrial flutter (AFL) shows a high success rate and effective for patients. However, operators experience difficulties in CTI ablation in some cases and need additional ablation for repeated recurrence. We investigated whether the SOUNDSTAR® (Biosense. Webster, Diamond Barr, CA, USA) catheter would be effective to select a CTI line of high therapeutic effect.
Methods
We have investigated the anatomy of around CTI by SOUNDSTAR® catheter and decided the CTI line using the anatomical information in AFL ablation (Figure1). We assumed two CTI lines of medial and lateral line. Medial CTI (M-CTI) line was more common and shorter line. Lateral CTI (L-CTI) line was uncommon and slightly longer line. We use 3.5mm tip catheter with NxT steerable introducer. The target Ablation Index (AI) was 400, and the target VisTtag™ interval was 6 mm or less.
Results
A total 30 of AFL ablated cases were investigated retrospectively. We surveyed 15 cases in M-CTI group and 15 cases in L-CTI group. Comparing the length of CTI in all cases, the length of M-CTI line was shorter than L-CTI line (M-CTI 32.1 ± 6.6mm vs. L-CTI 38.4 ± 8.3mm, n = 30, p <0.01). The atrial wall thickness of midsection and tricuspid valve (TV) side were thicker in M-CTI line (Midsection: M-CTI 4.0 ± 1.2mm vs. L-CTI 3.3 ± 0.8mm, n = 30, p <0.05, TV side: M-CTI 5.4 ± 1.4mm vs. L-CTI 4.3 ± 1.1mm, n = 30, p <0.05,). There was no difference in the required number of points to complete initial line (M-CTI 8.4 ± 1.6 vs. L-CTI 8.1 ± 1.7, n = 15, ns). Eustachian ridge in IVC side was thicker and higher in the M-CTI group (3.4 ± 3.3mm vs. 0.9 ± 1.9mm, n =30, p <0.01) and ablation on the Eustachian ridge showed instability of catheter placement. A lot of RF delivery was required on Eustachian ridge in M-CTI (2.6 ± 0.6 vs. 2.1 ± 0.7, n =15, p <0.05) and AI had resulted lower in M-CTI (351 ± 42.8 vs. 381 ± 27.1, n =15, p <0.05). Recurrence is more common in M-CTI group (9/15, 60% vs. 3/15, 20%). Recurrence sites in M-CTI group were distributed ((IVC side 3/9 (33%), midsection 5/9 (56%), TV side 5/9 (56%)) and multiple recurrences occurred in 3/9 (33%). Recurrence sites in L-CTI were only midsection of CTI (3/3, 100%).
Conclusions
CTI ablation at the shorter distance M-CTI, which is commonly selected, resulted in more recurrences due to the unevenness including Eustachian ridge and the myocardium thickness. However, ablation at slightly longer L-CTI line showed lower recurrence and effective for CTI ablation.

739SERCA2 Cys674 modification lead to ventricular arrhythmia due to impaired sarcoplasmic reticulum Ca2+ handling. Europace 2020.

Abstract
Abstract
Background
Sarcoplasmic reticulum Ca2+-ATPase2 (SERCA2) plays an important role in intracellular Ca2+ handling. Under pathological conditions, oxidative stress leads to irreversible oxidation of Cys674 on SERCA2 which causes intracellular Ca2+ overload. Intracellular Ca2+ overload is known as the cause of ventricular arrhythmia, but the relation between SERCA2 function and ventricular arrhythmia remains unclear.
Purpose
To investigate the role of Cys674 on SERCA2 in the intracellular Ca2+ handling and the induction of ventricular arrhythmia.
Methods
We employed SERCA2 Cys674Ser heterozygote knock-in mice (SKI) which mimics oxidative modification of Cys674 on SERCA2. Continuous infusion of angiotensin (ANG) (3mg/kg/day) or distilled water were performed both in wild type mice (WT) and SKI for a week. After 1 week, electrophysiological study and intracellular Ca2+ transient measurement were performed.
Results
ANG elevated blood pressure and represented cardiac hypertrophy with fibrosis similarly both in WT and SKI. The mRNA expression of calcium/calmodulin-dependent protein kinase-II (CaMKII), ryanodine receptor (RyR) and sodium-calcium exchanger (NCX) was increased in SKI heart compared with WT. QTc interval was prolonged in SKI compared with WT, which was markedly prolonged with ANG infusion. Under programmed electrical stimulation, only SKI with ANG showed high incidence of pacing induced ventricular arrhythmia (0/11 in WT/SKI control, 0/14 in WT with ANG vs. 8/14 in SKI with ANG, P < 0.01). In Ca2+ transient measurement, the peak Ca2+ transient amplitude (F/F0) was decreased (WT: 1.81 vs. SKI: 1.46, P < 0.01) and the time to 50% of cytosolic Ca2+ extrusion (T50) was prolonged (WT: 152.6ms vs. SKI: 202.3ms, P < 0.05) in SKI with ANG, suggesting decreased sarcoplasmic reticulum Ca2+ content and impaired SERCA2 activity in SKI with ANG. Intraperitoneal administration of dantrolene sodium (DAN) which inhibit Ca2+ leakage from RyR receptor normalized decreased F/F0 and prolonged T50 in SKI with ANG (Fig. 1 A, B). DAN also prevented QTc prolongation and decreased the incidence of ventricular arrhythmia in SKI with ANG (8/14 in SKI with ANG vs. 2/13 in SKI with ANG + DAN, P < 0.05) (Fig. 2).
Conclusions
The loss of thiol on Cys674 under pathological condition resulted in impaired Ca2+ handling and high incidence of ventricular arrhythmia which were ameliorated by inhibition of Ca2+ leakage through RyR. Oxidative modification of Cys674 on SERCA2 might contribute to Ca2+ mishandling and arrhythmogenesis.

Abstract
We treated a 66-year-old Japanese male with unresectable hepatocellular carcinoma (u-HCC) for multiple (>5) liver tumors (maximum 2.6 cm in size, Child-Pugh B score 7) in September 2018. The patient had a history of psoriasis vulgaris and sorafenib (SOR) was introduced (800 mg/day) because of transcatheter arterial chemoembolization (TACE) refractoriness. However, psoriasis vulgaris exacerbation and a high fever were observed 2 weeks later, and the patient was admitted, after which improvement of psoriasis vulgaris was obtained with external medicine administration and SOR intake discontinuation. Few reports have noted exacerbation of psoriasis vulgaris caused by SOR treatment.

Abstract
Abstract
Introduction
Watch-PAT is a sleep evaluation device that measures the peripheral blood volume continuously with a probe attached to a fingertip and does not use an electroencephalogram or a nasal cannula. There has been no report on the usefulness of watch-PAT to determine the apnea diagnosis and continuous positive airway pressure (CPAP) use effects in split-night sleep study.
Methods
The consent of the study was obtained. Watch-PAT was simultaneously worn on a patient admitted for split-night polysomnography. The apnea-hypopnea index (AHI) obtained from PSG and the pAHI gained from the watch-PAT were measured when not using CPAP and when using CPAP respectively. And also we examined whether the reduction rates of AHI and pAHI could be correlated.
Results
38 subjects (32 men, age 55 ± 13 years old). BMI 28.3 ± 5.7 kg / m2. When CPAP was not used, AHI was 57.2 ± 23.3 / h and pAHI was 50.8 ± 20.3 / h (r = 0.93, p < 0.0001), when CPAP was used, AHI was 5.2 ± 4.5 /h and pAHI was 6.2 ± 4.5 h (r = 0.82, p < 0.0001), AHI reduction rate was 90.4 ± 8.0% and pAHI reduction rate was 85.4 ± 14.6% (r = 0.76, p < 0.0001).
Conclusion
It was suggested that Watch-PAT had a good correlation with AHI at split night-sleep study.

High-Temperature Charge-Stripe Correlations in La_{1.675}Eu_{0.2}Sr_{0.125}CuO_{4}. PHYSICAL REVIEW LETTERS 2020; 124:187002.

Abstract
We use resonant inelastic x-ray scattering to investigate charge-stripe correlations in La_{1.675}Eu_{0.2}Sr_{0.125}CuO_{4}. By differentiating elastic from inelastic scattering, it is demonstrated that charge-stripe correlations precede both the structural low-temperature tetragonal phase and the transport-defined pseudogap onset. The scattering peak amplitude from charge stripes decays approximately as T^{-2} towards our detection limit. The in-plane integrated intensity, however, remains roughly temperature independent. Therefore, although the incommensurability shows a remarkably large increase at high temperature, our results are interpreted via a single scattering constituent. In fact, direct comparison to other stripe-ordered compounds (La_{1.875}Ba_{0.125}CuO_{4}, La_{1.475}Nd_{0.4}Sr_{0.125}CuO_{4}, and La_{1.875}Sr_{0.125}CuO_{4}) suggests a roughly constant integrated scattering intensity across all these compounds. Our results therefore provide a unifying picture for the charge-stripe ordering in La-based cuprates. As charge correlations in La_{1.675}Eu_{0.2}Sr_{0.125}CuO_{4} extend beyond the low-temperature tetragonal and pseudogap phase, their emergence heralds a spontaneous symmetry breaking in this compound.

Abstract
AIM An easily performed method for examination of muscle abnormalities is anticipated. We aimed to elucidate the clinical usefulness of simple assessments for muscle abnormality including a simple five-item questionnaire (SARC-F) in chronic liver disease patients. METHODS From February to July 2019, 383 outpatients (median age 71 years, 259 men; chronic hepatitis (CH) : liver cirrhosis Child-Pugh A : liver cirrhosis Child-Pugh B : liver cirrhosis Child-Pugh C = 157:176:39:11) who underwent a computed tomography examination were enrolled. SARC-F, previously reported cut-off values for muscle strength decline (MSD; handgrip), pre-muscle volume loss (pre-MVL), calf circumference and finger-circle test results were used, and these results were analyzed retrospectively. RESULTS A high SARC-F score (≥4) was observed in 25 patients, and a low score (<4) in 358 patients. The frequency of high SARC-F increased significantly with progression of chronic liver disease (chronic hepatitis : liver cirrhosis Child-Pugh A : liver cirrhosis Child-Pugh B/C = 2.5%:8.0%:14.0%, P=0.010). MSD frequency was 22.4% in men and 41.1% in women. Muscle volume loss and pre-MVL were noted in 22% and 30.5%, respectively, of the male patients, and 9.7% and 32.3%, respectively, of the female patients. In cases with high SARC-F and MSD, calf circumference and finger-circle abnormalities were found in 56% and 40.0% of patients, respectively, whereas those values for patients with low SARC-F and MSD were 14.5% and 10.6%, respectively (P < 0.001, for each; positive/negative predictive values: 0.560/0.855 and 0.400/0.894, respectively). Each SARC-F item showed a good area under the curve for MSD, but not pre-MVL. CONCLUSION SARC-F score in combination with MSD and calf circumference or finger-circle test results may be an easy and simple method for surveillance of chronic liver disease patients with a high risk of sarcopenia and decline of quality of life.

Abstract
Bone structure and function are maintained by well-regulated bone metabolism and remodeling. Although the underlying molecular and cellular mechanisms are now being understood, physiological and pathological states of bone are still difficult to predict due to the complexity of intercellular signaling. We have now developed a novel in silico experimental platform, V-Bone, to integratively explore bone remodeling by linking complex microscopic molecular/cellular interactions to macroscopic tissue/organ adaptations. Mechano-biochemical couplings modeled in V-Bone relate bone adaptation to mechanical loading and reproduce metabolic bone diseases such as osteoporosis and osteopetrosis. V-Bone also enables in silico perturbation on a specific signaling molecule to observe bone metabolic dynamics over time. We also demonstrate that this platform provides a powerful way to predict in silico therapeutic effects of drugs against metabolic bone diseases. We anticipate that these in silico experiments will substantially accelerate research into bone metabolism and remodeling.

Abstract
AIM The relationship between congenital protein S (PS) deficiency and complications during pregnancy remains unclear, partly due to the difficulty of precisely evaluating the PS level with conventional assays and the physiological decrease of PS during pregnancy. A new PS assay was developed to measure the total PS antigen and activity quantitatively and calculate PS-specific activity. This study aimed to evaluate the plasma PS dynamics during pregnancy using the new PS assay and establish the reference interval for pregnant women. METHODS A total of 253 pregnant women without a personal or family history of thromboembolism were recruited. Blood samples were obtained in the first, second and third trimesters and at one month post-partum. The total PS antigen, activity, and PS-specific activity were studied. Results were analyzed by the repeated measures single-factor anovas followed by a post-hoc test using Excel Statistics. RESULTS The mean ± standard deviation (IU/mL) of the total PS antigen levels in the first, second and third trimesters and 1 month post-partum were 0.67 ± 0.12, 0.67 ± 0.09, 0.68 ± 0.11 and 0.92 ± 0.13, respectively. The total PS activity (IU/mL) in the first, second and third trimesters and 1 month post-partum were 0.69 ± 0.14, 0.59 ± 0.10, 0.58 ± 0.12 and 0.87 ± 0.15, respectively. The PS-specific activity was within the normal range of nonpregnant women in the first trimester (1.02 ± 0.10) but decreased in the second and third trimesters (0.88 ± 0.09 and 0.85 ± 0.09, respectively) before increasing in the post-partum period (0.94 ± 0.08). CONCLUSION The total PS antigen and activity decrease throughout pregnancy, while the PS-specific activity decreases in the second and third trimesters.

Zinc deficiency as an independent prognostic factor for patients with early hepatocellular carcinoma due to hepatitis virus. Hepatol Res 2020; 50:92-100. [PMID: 31729124 DOI: 10.1111/hepr.13430] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/17/2019] [Revised: 09/17/2019] [Accepted: 09/18/2019] [Indexed: 12/13/2022]
Abstract
AIM Although a reduced serum zinc level is often observed in patients with chronic liver disease due to hepatitis virus, its prognostic importance has not been adequately investigated. This study aimed to elucidate the association of zinc deficiency with prognosis, especially in early hepatocellular carcinoma (HCC) patients. METHODS From 2005 to 2018, 466 patients with naïve HCC due to hepatitis virus were enrolled (327 men, 139 women; median age 70 years; hepatitis C virus [HCV] n = 389, hepatitis B virus [HBV] n = 69, hepatitis C virus and hepatitis B virus n = 8; Child-Pugh A n = 367, Child-Pugh B n = 82; Child-Pugh C n = 17; TNM-LCSGJ stage I n = 150, stage II n = 181, stage III n = 91, stage IVa n = 26, state IVb n = 18). Of the 466 patients, 287 were within the Milan criteria (early HCC) and treated curatively. Zinc deficiency was defined as <60 μg/dL. Clinical records and prognostic factors were retrospectively evaluated. RESULTS The levels of serum zinc became lower with chronic liver disease progression (Child-Pugh A, B, C: 64.3 ± 14.3, 52.3 ± 15.7, 48.4 ± 13.5 μg/dL, respectively; P < 0.001). In early HCC patients treated curatively, overall survival and recurrence rates were better in patients treated curatively and without zinc deficiency as compared with patients with zinc deficiency (3-year overall survival 86.5% vs. 77.2%, 5-year overall survival 73.5% vs. 43.8%, P < 0.001; 3-year recurrence 44.8% vs. 58.3%, 5-year recurrence 56.8% vs. 77.5%, P = 0.002). Not only infection control of hepatitis virus (sustained virological response in HCV or nucleos(t)ide analogs in HBV; HR 0.078, P < 0.001), but also zinc deficiency (HR 1.773, P = 0.041) were significant prognostic factors for death. CONCLUSION Serum levels of zinc were reduced in association with chronic liver disease grade progression. In addition to infection control of hepatitis virus, zinc deficiency might be a significant prognostic factor for survival in patients with early HCC due to viral hepatitis treated curatively.

Abstract
Abstract
Introduction
Metabolic syndrome (MetS) is well known as the risk of cardiovascular diseases associated with endothelial dysfunction and induces steatohepatosis. Insulin resistance is a major character of MetS, which affects intracellular signaling pathways and endothelial function. Extracellular signal-regulated kinase (ERK) is a major component of insulin signal and many of vasoactive peptides, which were released in MetS, can activate it in endothelium. However, the role of endothelial ERK in nitric oxide (NO) bioactivity in MetS in in vivo has been unknown.
Purpose
The aim of this study is to clarify the role of endothelial ERK2 on NO bioactivity in mice model of MetS.
Methods and results
We created endothelial specific ERK2 knock out mice (EE2KO) crossing Tie2-Cre mice and ERK2 flox mice and fed them with normal or high-fat/high-sucrose diet (HFHSD) for 24 weeks. Serum glucose and insulin levels and HOMA-IR were lowered in EE2KO with HFHSD without changing body weight. In wild type mice (WT) with HFHSD, nonalcoholic fatty liver disease (NAFLD) activity score, fibrosis score and serum ALT level were increased, all of which were blunted in EE2KO. EE2KO with HFHSD lowered systolic blood pressure (WT: 123.7±5.83 mmHg, EE2KO: 101.4±3.66 mmHg, P<0.01, N=8) without changing heart rate, which was increased to the same levels with L-NAME, an endothelial NO synthase inhibitor, in both groups. Serum NO levels measured with serum nitrite/nitrate concentrations were increased in EE2KO with HFHSD (WT: 23.10±3.74 μmol/l, EE2KO: 41.71±6.73 μmol/l, P<0.05, N=12). Endothelial function was assessed with the isometric tension measurement of aortic rings with acetylcholine (ACh). ACh-induced relaxation was improved in EE2KO with HFHSD. Superoxide production of aorta from EE2KO was lowered than WT with HFHSD in dihydroethidium (DHE) staining. S18886, an antagonist of the thromboxane A2-prostanoid (TP) receptor, decreased superoxide production of aorta in DHE staining resulting in improving endothelial function in the isometric tension measurement of aortic rings. Oral administrations of S18886 decreased systolic blood pressure, serum fasting glucose and insulin levels, and surprisingly improved steatohepatosis by decreasing NAFLD activity score and fibrosis score.
Relaxation of aortic rings with ACh
Conclusions
Endothelial ERK2/TP receptor pathway increases superoxide production and decreased NO bioactivity, resulting in deteriorating endothelial function, insulin resistance and steatohepatosis, which were improved by antagonist of the TP receptor in mice model of MetS. The present study indicates that ERK2/TP pathway could be a therapeutic target for complications of MetS.

Abstract
This paper describes diagnosis, treatment, and control of acute venous thromboembolism (VTE) and antithrombotic prophylactic management during pregnancy and puerperium, especially in women with inherited thrombophilia. VTE is currently one of the three main causes of maternal morbidity in Japan. With approximately 0.05%-0.08% incidence rate per total number of births, it is becoming increasingly comparable with other developed countries. Pregnancy is characterized by high blood clotting potential due to increased coagulation factors, decreased anticoagulant activity, and fibrinolysis. Additionally, unique obstetric risk factors exist, such as cesarean section, prolonged bed rest, obesity, preeclampsia, and dehydration due to hyperemesis. Moreover, notable risk factors for VTE in pregnancy and puerperium for patients with inherited thrombophilia (e.g., deficiencies in antithrombin, protein C, and protein S) and acquired thrombophilia (e.g., antiphospholipid antibodies, history of VTE) have been reported; this study describes inherited thrombophilia in details.

P4601Reduced exercise capacity and clinical outcomes following acute myocardial infarction. Eur Heart J 2019.

Abstract
Abstract
Background
Reduced exercise capacity is known to be an important predictor of poor prognosis and disability in patients with cardiovascular diseases and chronic heart failure, and even members of the general population. However, data about exercise capacity assessed by cardiopulmonary exercise testing (CPX) in acute myocardial infarction (AMI) patients who underwent primary percutaneous coronary intervention (PCI) is scarce. The purpose of this study is to assess the associated factors and clinical influence of exercise capacity measured by CPX in AMI patients.
Methods
Among 594 consecutive AMI patients who underwent primary PCI, we examined 136 patients (85.3% men, 64.9±11.9 years) who underwent CPX during hospitalization for AMI. CPX was usually performed five days after the onset of AMI. Reduced exercise capacity was defined as peak oxygen consumption (peak VO2) ≤12. Clinical outcomes including all-cause death, myocardial infarction, and hospitalization due to heart failure were followed.
Results
Among 136 patients, reduced exercise capacity (peak VO2 ≤12) was seen in 38 patients (28%). Patients with reduced exercise capacity were older, more likely to have hypertension, and had lower renal function. In echocardiography, patients with reduced exercise capacity had higher E/e' and larger left atria. Median follow-up term was 12 months (interquartile range: 9–22). The occurrence of composite endpoints of all-cause death, myocardial infarction, and hospitalization due to heart failure was significantly higher in patients with peak VO2≤12 than those with peak VO2>12 (p<0.001). Multivariate logistic analysis showed that E/e' (Odds ratio, 1.19, 95%, confidence interval 1.09 to 1.31, p<0.001) was an independent predictor of reduced exercise capacity (peak VO2≤12).
Cumulative incidence of clinical events
Conclusion
Diastolic dysfunction is associated with reduced exercise capacity following successful primary PCI in AMI patients and may lead to poorer clinical outcomes.

Abstract
Abstract
Background
Severity of functional limitations (FLs) has been considered as a prognostic factor in patients with heart failure (HF). However, trajectory patterns of FLs after discharge and their associated factors have remained unclear.
Purpose
This study aimed to explore trajectories of FLs after discharge and to examine clinical characteristics based on the identified trajectories.
Methods
This study was performed as a part of a multicenter cohort study. The cohort study enrolled hospitalized patients due to acute HF or exacerbation of chronic HF and who were able to walk at discharge. Patients with severe cognitive or psychological disorders or less than 6-month life expectancy were excluded. FLs were assessed using Performance Measure for Activities of Daily Living-8 (PMADL-8; higher scores indicate worse FLs) at discharge and 1-, 6-, 10- and 14-month after discharge. To identify FLs trajectories getting worse after discharge, we excluded patients already having severe FLs at discharge (PMADL-8 ≥21, a cut off value for predicting poor prognosis). Group-based trajectory modeling (GBTM) was conducted to identify distinct PMADL-8 trajectories. Then, associated factors of trajectory group that showed increasing FLs after discharge were examined using logistic regression analysis adjusted for potential confounders.
Results
A total of 953 patients were included in the analysis (age: 70.6±11.8 years, men: 70.9%, left ventricular ejection fraction <40%: 41.3%). GBTM identified four PMADL-8 trajectories: two separate trajectories where PMADL-8 remained low (T1: 14.1%, T2: 31.3%), mildly increasing PMADL-8 trajectory (T3: 41.0%) and rapidly increasing PMADL-8 trajectory (T4: 13.6%) (Figure). Logistic regression analysis showed that age (odds ratio 1.05, per 1 year; 95% confidence interval 1.02–1.07), women (2.12; 1.31–3.45), brain natriuretic peptide ≥200 pg/mL (1.88; 1.10–3.21), estimated glomerular filtration rate <30 mL/min/1.73m2 (2.50; 1.41–4.41), depression (2.34; 1.44–3.80), and re-hospitalization due to HF during 1-year follow-up (2.85; 1.56–5.21) were independent associated factors of T4 group.
Figure 1. Trajectories of PMADL-8
Conclusions
The high-risk population for increasing FLs after discharge was identified by GBTM. The findings of this study suggest the importance of long-term HF management for preventing FLs after discharge especially among those with older age, female gender and depression.

296Clinical benefit of assessing cognitive function in frail patients with heart failure: a multicenter prospective cohort study. Eur Heart J 2019.

Abstract
Abstract
Background
Cognitive decline is highly prevalent in patients with heart failure (HF) and increases the risk of hospital readmission or mortality due to poor self-care ability. Although cognitive decline often coexists with physical frailty (PF) in HF, the clinical utility of combined assessment of both cognitive function and PF remains unclear.
Purpose
The aim of this study was to examine the prognostic value of assessing cognitive function and PF in patients with HF.
Methods
This prospective study was performed as a multicenter cohort study in Japan (FLAGSHIP). We enrolled 1611 patients admitted for acute HF or exacerbation of chronic HF and who were able to walk at discharge. Patients with severe dementia [Mini-Mental State Examination (MMSE) scores <18], severe psychological disorders or less than 6-month life expectancy were excluded. From data at discharge, we collected data on cognitive function, PF, age, gender, New York Heart Association class, left ventricular ejection fraction, brain natriuretic peptide, estimate glomerular filtration rate, hemoglobin, depression (5-item geriatric depression scale ≥2) and comorbidities, including atrial fibrillation, diabetes mellitus, stroke, and hyponatremia. PF was defined as ≥2 of the followings based on our previous publication: usual walking speed <0.8 m/s; grip strength <26 kg (men) or <17 kg (women); Performance Measure of Activity in Daily Living-8 ≥21; body mass index <20 kg/m2. Cognitive function was assessed by MMSE. We selected the optimal cutoff point of MMSE that predict a worse outcome by the receiver operating characteristic (ROC) curve analysis. Study outcome was a composite outcome of rehospitalization for worsening HF or all-cause mortality within 2 years after discharge. We used Cox proportional-hazard models to examine the association between the presence of cognitive decline and PF and 2-years prognosis, controlling for potential confound factors.
Results
A total of 507 events (31.5%) were observed (400 HF rehospitalization, 27 cardiac death, 80 non-cardiac death). The optimal cutoff point of MMSE was 28 (the area under the ROC curve: 0.58, p<0.01, sensitivity: 71.0%, specificity: 41.0%). There was a significant difference in event-free survival across the groups stratified by cognitive decline (MMSE <28) and PF (Figure). After adjusting for all variables, coexistence of both cognitive decline and PF was independently associated with 2-years prognosis (hazard ratio: 1.52, 95% confidence interval: 1.19–1.94).
Conclusion
Our data shows that even a slight decline in cognitive function leads to an increased risk of death or HF rehospitalization in frail patients with HF. Combined assessment both cognitive function and PF improves risk stratification for readmission and mortality in patients with HF.

Low antithrombin levels accompanied by high urine protein/creatinine ratios are predictive of acute kidney injury among CS patients with preeclampsia. J Matern Fetal Neonatal Med 2019; 34:1550-1556.

Abstract
OBJECTIVES Previous acute kidney injury (AKI) is reportedly a risk factor for future preeclampsia (PE), and PE in current pregnancies may trigger the onset of AKI. In this study, we identified risk factors for AKI among Cesarean section (CS) patients with PE. METHODS We performed a retrospective study at a single center. Among 4602 deliveries between January 2017 and July 2018, 944 women underwent CS. Of these, 90 women had hypertensive disorders during their pregnancies, with 53 diagnoses of PE and 37 diagnoses of gestational hypertension. Medical records of the 90 women were reviewed retrospectively. RESULTS The rate of AKI was significantly higher in the PE group than in the GH group (17 versus 3%, p < .05). Univariate analyses of the PE group identified low preoperative serum albumin levels, low antithrombin III (ATIII) activities, and urine protein/creatinine ratios (U-P/Cr) as significant predictors of AKI. Cutoff values for these factors were calculated using ROC analyses, and the combination of ATIII and U-P/Cr, which were poorly correlated, was predictive of AKI. Specifically, the proportion of AKI in patients with low ATIII-high U-P/Cr was 50% (7/14), higher than that among patients with high ATIII-low U-P/Cr (0%, 0/19, p < .05), low ATIII-low U-P/Cr (10%, 1/10, p < .05), and high ATIII-high U-P/Cr (10%, 1/10, p < .05). CONCLUSIONS These data demonstrate that lower preoperative serum albumin levels, ATIII activities, and heavy proteinuria among CS patients with PE are risk factors for AKI.

Abstract
OBJECTIVES To describe the health information preferences in middle-aged Japanese workers based on health literacy (HL) levels and presence of medications. STUDY DESIGN A cross-sectional study. METHODS We performed a web-based questionnaire survey with Japanese workers aged below 60 years. HL was assessed using the total score of communicative skills (five items) and critical skills (four items) from the 14-item Health Literacy Scale. Regarding their health information preferences, participants were asked about the health information they wanted (four items), could easily understand (six items), or easily use (two items) and answered on a 4-point scale (strongly agree/agree/disagree/strongly disagree). The percentages of the affirmative responses (strongly agree or agree) were compared among tertiles based on the HL score. RESULTS We obtained data from a total of 3387 volunteers, of whom 510 participants were on either antihypertensive, lipid-lowering, or antidiabetic drugs. Compared with the high HL and middle HL groups, low HL had fewer affirmative responses to most health information items. Health information items received 70% of affirmative responses even in the low HL level. They were visually shown by figures or pictures, highlighted by colors for important points, could be read in 1-2 min, and were accessed on the Internet, regardless of the presence of medications. Additionally, the explanation for mechanisms of medications or lifestyle to prevent or improve diseases showed high affinity in all HL levels, only for those on medications. CONCLUSIONS This result generates a hypothesis that low HL individuals have a low interest in health information. Our data showed several possible forms of health information with high affinity based on HL levels that would help plan future population approaches.

Abstract
PURPOSE A prospective assessment of the risk of spontaneous preterm delivery (sPTD) by evaluating temporal changes in cervical measurements. METHODS We analyzed clinical variables, focusing on cervical length (CL) and lower uterine segment (LUS) length (LUSL) as measured by transvaginal ultrasonography in 727 pregnant Japanese women. RESULTS In women undergoing term deliveries, CL increased from gestational week (GW) 8-25. In contrast, the combination of CL and LUSL (ComL for "combined length") gradually decreased and sole LUSL became almost 0 mm by GW 25. Univariate logistic regression analysis suggested that a history of PTD was a risk factor for sPTD. CL, LUSL, and ComL were not significant predictors of sPTD. CONCLUSION To assess the risk of sPTD in the second trimester, it is not necessary to distinguish the cervix from the LUS.

Abstract
Organogenesis is a self-organizing process of multiple cells in three-dimensional (3D) space, where macroscopic tissue deformations are robustly regulated by multicellular autonomy. It is clear that this robust regulation requires cells to sense and modulate 3D tissue formation across different scales, but its underlying mechanisms are still unclear. To address this question, we developed a versatile computational model of 3D multicellular dynamics at single-cell resolution and combined it with the 3D culture system of pluripotent stem cell-derived optic-cup organoid. The complementary approach enabled quantitative prediction of morphogenesis and its corresponding verification and elucidated that the macroscopic 3D tissue deformation is fed back to individual cellular force generations via mechanosensing. We hereby conclude that mechanical force plays a key role as a feedback regulator to establish the robustness of organogenesis.
