In-house molecular diagnosis of diffuse glioma updating the revised WHO classification by a platform of the advanced medical care system, Senshin-Iryo. Neuropathology 2024. [PMID: 38477051 DOI: 10.1111/neup.12970] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2023] [Revised: 02/13/2024] [Accepted: 02/15/2024] [Indexed: 03/14/2024]
Abstract
Since the World Health Organization (WHO) 2016 revision, the number of molecular markers required for diffuse gliomas has increased, placing a burden on clinical practice. We have established an in-house, molecular diagnostic platform using Senshin-Iryo, a feature of Japan's unique healthcare system, and partially modified the analysis method in accordance with the WHO 2021 revision. Herein, we review over a total 5 years of achievements using this platform. Analyses of IDH, BRAF, and H3 point mutations, loss of heterozygosity (LOH) on 1p/19q and chromosomes 10 and 17, and MGMT methylation were combined into a set that was submitted to Senshin-Iryo as "Drug resistance gene testing for anticancer chemotherapy" and was approved in August 2018. Subsequently, in October 2021, Sanger sequencing for the TERT promoter mutation was added to the set, and LOH analysis was replaced with multiplex ligation-dependent probe amplification (MLPA) to analyze 1p/19q codeletion and newly required genetic markers, such as EGFR, PTEN, and CDKN2A from WHO 2021. Among the over 200 cases included, 54 were analyzed after the WHO 2021 revision. The laboratory has maintained a diagnostic platform where molecular diagnoses are confirmed within 2 weeks. Initial expenditures exceeded the income from patient copayments; however, it has gradually been reduced to running costs alone and is approaching profitability. After the WHO 2021 revision, diagnoses were confirmed using molecular markers obtained from Senshin-Iryo in 38 of 54 cases (70.1%). Among the remaining 16 patients, only four (7.4%) were diagnosed with diffuse glioma, not elsewhere classified, which was excluded in 12 cases where glioblastoma was confirmed by histopathological diagnosis. Our Senshin-Iryo trial functioned as a salvage system to overcome the transition period between continued revisions of WHO classification that has caused a clinical dilemma in the Japanese healthcare system.

Abstract
PURPOSE Despite the growing recognition of the importance of hypertension in patients with cancer, little is known about whether high blood pressure (BP) among patients with cancer is associated with incident heart failure (HF) and other cardiovascular disease (CVD) events and what BP levels are linked to these events. We examined the association of BP classification on the basis of the 2017 American College of Cardiology/American Heart Association BP guideline with the risk of HF and CVD events in patients with cancer. METHODS We studied 33,991 patients with a history of breast, colorectal, or stomach cancer (median age, 53 years; 34.1% men). Patients receiving treatment with BP-lowering medications or having a history of CVD including HF were excluded. Using BP measurements at baseline, 33,991 participants were categorized as having normal BP (n = 17,444), elevated BP (n = 4,733), stage 1 hypertension (n = 7,502), or stage 2 hypertension (n = 4,312). The primary outcome was HF. RESULTS Over a mean follow-up of 2.6 ± 2.2 years, 779 HF events were recorded. After multivariable adjustment, the hazard ratios (HRs) for HF were 1.15 (95% CI, 0.93 to 1.44) for elevated BP, 1.24 (95% CI, 1.03 to 1.49) for stage 1 hypertension, and 1.99 (95% CI, 1.63 to 2.43) for stage 2 hypertension. A stepwise increase in risk with BP categories was also observed in other CVD events. This association was observed even in patients undergoing active cancer treatment. The relationship between hypertension and the risk of developing HF in patients with cancer was confirmed in the Korean National Health Insurance Service database. CONCLUSION Medication-naïve stage 1 and 2 hypertension was associated with a greater risk of HF and other CVD events in patients with cancer. Our results suggest the importance of multidisciplinary collaboration (eg, oncologists and cardiologists) to establish the optimal management strategy for hypertension in patients with cancer.

The association of BP with cardiovascular outcomes in patients with dipstick proteinuria and preserved kidney function. Hypertens Res 2023; 46:856-867. [PMID: 36658302 DOI: 10.1038/s41440-022-01146-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Revised: 10/12/2022] [Accepted: 10/28/2022] [Indexed: 01/20/2023]
Abstract
Little is known about the relationship between blood pressure (BP) and incident cardiovascular disease (CVD) in people with proteinuria and a preserved estimated glomerular filtration rate (eGFR). This study sought to investigate the association of BP with CVD risk in adults with proteinuria and preserved eGFR. We studied 188,837 individuals with proteinuria and preserved eGFR ≥60 mL/min/1.73 m2. We categorized individuals who were not taking BP-lowering medications into four groups based on the 2017 American College of Cardiology/American Heart Association BP guideline and categorized those who were taking BP-lowering medications using the same BP ranges. The primary outcome was a composite CVD endpoint that included myocardial infarction, angina pectoris, stroke, and heart failure. Over a mean follow-up of 1,050 days, 7,039 CVD events were identified. Compared with normal BP, stage 1 hypertension (hazard ratio [HR]: 1.30, 95% confidence interval [95% CI]: 1.21-1.40) and stage 2 hypertension (HR: 2.17, 95% CI: 2.01-2.34) were associated with an increased risk for CVD events among medication-naïve individuals. Only stage 2 hypertension range (HR: 1.19, 95% CI: 1.02-1.38) was associated with an increased CVD event risk among people taking BP-lowering medications. Restricted cubic spline analysis showed that the risk of CVD events increased monotonically with BP at an SBP/DBP > 120/80 mmHg among medication-naïve individuals, but risk increased only at an SBP/DBP > 140/90 mmHg among individuals taking BP-lowering medications. In conclusion, among people with proteinuria and preserved eGFR, stage 1 and stage 2 hypertension were associated with a greater risk of CVD among medication-naïve individuals, whereas only stage 2 hypertension was associated with an increased CVD risk among those taking BP-lowering medications.

Systematic Review of the Effectiveness of Community Intervention and Health Promotion Programs for the Prevention of Non-Communicable Diseases in Japan and Other East and Southeast Asian Countries. Circ Rep 2022; 4:149-157. [PMID: 35434409 PMCID: PMC8977194 DOI: 10.1253/circrep.cr-21-0165] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2022] [Revised: 02/27/2022] [Accepted: 03/10/2022] [Indexed: 11/09/2022] Open
Abstract
Background: Non-communicable diseases (NCDs) are the leading cause of death worldwide. However, current evidence regarding the efficacy and cost-effectiveness of community intervention and health promotion programs for NCDs, specifically hypertension, obesity, diabetes, and dyslipidemia, in East and Southeast Asia has not yet been systematically reviewed. We systematically reviewed the literature from East and Southeast Asian countries to answer 2 clinical questions: (1) do health promotion programs for hypertension, obesity, diabetes, and dyslipidemia reduce cardiovascular events and mortality; and (2) are these programs cost-effective? Methods and Results: Electronic literature searches were performed across Medline, Cochrane Library, and Ichushi using key words and relevant subject headings related to randomized controlled trials, comparative studies, quasi-experimental studies, or propensity score matching that met eligibility criteria that were defined for each question. In all, 3,389 records were identified, of which 12 full-text articles were reviewed. Three papers were from Japan, 7 were from China/Hong Kong Special Administrative Region, and 2 were from South Korea. None were from Southeast Asia. Four papers examined the effect of community intervention or health promotion on the incidence of cardiovascular events or mortality. Eight studies examined the cost-effectiveness of interventions. Conclusions: The literature review revealed that community intervention and health promotion programs for the control of NCDs are a cost-effective means of reducing cardiovascular events and mortality in East Asian countries.

Which Is More Important for Health: Sleep Quantity or Sleep Quality? CHILDREN-BASEL 2021; 8:children8070542.

Abstract
Sleep is one of the basic physiological processes for human survival. Both sleep quantity and sleep quality are fundamental components of sleep. This review looks at both sleep quantity and sleep quality, considering how to manage the complex but probably unavoidable physiological phenomenon of sleep. The need for sleep has marked variations between individuals, in addition to the effects of variable conditions. Studies on sleep quality started later than those on sleep quantity, beginning in 1989 when Ford and Kamerow revealed that insomnia increases the risk of psychiatric disorders. According to the nationwide research team on the quality of sleep (19FA0901), sleep quality is superior to sleep quantity as an index for assessing sleep, and that restfulness obtained through sleep is a useful index for assessing sleep quality. We should pay more attention to obtaining sleep of good quality (restfulness, no sleepiness, no need for more sleep, sufficient objective sleep depth, etc.), although there have not been enough studies on the associations between sleep quality and health or disorders in children and adolescents. Further studies using the deviation from an individual’s optimal sleep quantity may show us another aspect of the effects of sleep quantity on various life issues.

Impact of hospital volume on clinical outcomes of hospitalized heart failure patients: analysis of a nationwide database including 447,818 patients with heart failure. BMC Cardiovasc Disord 2021; 21:49. [PMID: 33494701 PMCID: PMC7836495 DOI: 10.1186/s12872-021-01863-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2020] [Accepted: 01/11/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Hospital volume is known to be associated with outcomes of patients requiring complicated medical care. However, the relationship between hospital volume and prognosis of hospitalized patients with heart failure (HF) remains not fully understood. We aimed to clarify the impact of hospital volume on clinical outcomes of hospitalized HF patients using a nationwide inpatient database. METHODS AND RESULTS We studied 447,818 hospitalized HF patients who were admitted from January 2010 and discharged until March 2018 included in the Japanese Diagnosis Procedure Combination database. According to the number of patients, patients were categorized into three groups; those treated in low-, medium-, and high-volume centers. The median age was 81 years and 238,192 patients (53%) were men. Patients who had New York Heart Association class IV symptom and requiring inotropic agent within two days were more common in high volume centers than in low volume centers. Respiratory support, hemodialysis, and intra-aortic balloon pumping were more frequently performed in high volume centers. As a result, length of hospital stay was shorter, and in-hospital mortality was lower in high volume centers. Lower in-hospital mortality was associated with higher hospital volume. Multivariable logistic regression analysis fitted with generalized estimating equation indicated that medium-volume group (Odds ratio 0.91, p = 0.035) and high-volume group (Odds ratio 0.86, p = 0.004) had lower in-hospital mortality compared to the low-volume group. Subgroup analysis showed that this association between hospital volume and in-hospital mortality among overall population was seen in all subgroups according to age, presence of chronic renal failure, and New York Heart Association class. CONCLUSION Hospital volume was independently associated with ameliorated clinical outcomes of hospitalized patients with HF.

Fasting plasma glucose and subsequent cardiovascular disease among young adults: Analysis of a nationwide epidemiological database. Atherosclerosis 2021; 319:35-41. [PMID: 33465660 DOI: 10.1016/j.atherosclerosis.2020.12.024] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/06/2020] [Revised: 12/17/2020] [Accepted: 12/17/2020] [Indexed: 12/13/2022]
Abstract
BACKGROUND AND AIMS Using a nationwide epidemiological database, we aimed to clarify the association of fasting plasma glucose (FPG) with subsequent cardiovascular disease (CVD) risk among young adults. METHODS AND RESULTS Medical records of 1,180,062 young adults (20-49 years old) without a prior history of CVD and who were not taking antidiabetic medications were extracted from the Japan Medical Data Center. We categorized the study population into four groups: normal, FPG level<100 mg/dL (1,007,747 individuals), normal-high, FPG level of 100-109 mg/dL (126,602 individuals), impaired fasting glucose (IFG), FPG level of 110-125 mg/dL (32,451 individuals), and diabetes mellitus (DM), FPG level ≥126 mg/dL (13,262 individuals). The mean age was 39.7 ± 6.9 years, and 57.0% of the study population were men. Mean follow-up period was 1201 ± 905 days on average. Multivariable Cox regression analysis showed that IFG (hazard ratio [HR]; 1.38) and DM (HR; 2.09) increased the risk of myocardial infarction. Normal-high (HR; 1.11), IFG (HR; 1.18), and DM (HR; 1.59) groups had an elevated angina pectoris risk. DM (HR; 1.31) increased the risk of stroke compared to normal FPG levels. Normal-high levels (HR; 1.10), IFG (HR; 1.22) and DM (HR; 1.58) elevated the risk of heart failure. DM (HR; 1.69) increased the risk of atrial fibrillation. CONCLUSIONS Our analysis of a nationwide epidemiological database demonstrated a close association of the FPG category with subsequent CVD risk. Our results exemplify the importance of optimal FPG maintenance for the primary prevention of CVD in young adults.

Abstract
Background: Nationwide data on transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (SAVR) in Japan are scarce. Methods and Results: Using a nationwide inpatient database, we analyzed patients undergoing TAVI (n=8,338) or SAVR (n=16,298) due to aortic stenosis between 2014 and 2017. The annual number of TAVI increased rapidly from 2014 to 2017, particularly in older patients. In-hospital deaths were lower and the length of hospital stay was shorter for patients undergoing TAVI than SAVR. Conclusions: TAVI has been penetrating in Japan as an alternative therapeutic option for aortic stenosis and is associated with acceptable clinical outcomes.

Restfulness from sleep and subsequent cardiovascular disease in the general population. Sci Rep 2020; 10:19674. [PMID: 33184438 PMCID: PMC7665021 DOI: 10.1038/s41598-020-76669-z] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2020] [Accepted: 11/02/2020] [Indexed: 01/25/2023] Open
Abstract
We aimed to clarify the association between restfulness from sleep and subsequent risk of cardiovascular disease (CVD). Medical records of 1,980,476 individuals with neither prior history of CVD nor sleep disorders were extracted from the Japan Medical Data Center. Restfulness from sleep was subjectively assessed using information from the questionnaires at initial health check-ups. The mean age was 45 ± 11 years and 1,184,937 individuals were men. Overall, 1,197,720 individuals (60.5%) reported having good restfulness from sleep. The mean follow-up period was 1122 ± 827 days. Myocardial infarction, angina pectoris, stroke, heart failure, and atrial fibrillation occurred in 3673 (0.2%), 30,241 (1.5%), 13,546 (0.7%), 28,296 (1.4%), and 8116 (0.4%) individuals, respectively. Multivariable Cox regression analyses including age, sex, and other CVD risk factors after multiple imputation for missing values showed that good restfulness from sleep was associated with lower incidence of myocardial infarction (hazard ratio [HR] 0.89, 95% confidence interval [CI] 0.83-0.95), angina pectoris (HR 0.85, 95% CI 0.83-0.87), stroke (HR 0.85, 95% CI 0.82-0.88), heart failure (HR 0.86, 95% CI 0.84-0.88), and atrial fibrillation (HR 0.93, 95% CI 0.89-0.97). The association of restfulness from sleep with CVD events was pronounced in subjects with younger age and female sex. In conclusion, good restfulness from sleep may be associated with the lower risk of myocardial infarction, angina pectoris, stroke, heart failure, and atrial fibrillation. Further studies are required to clarify the underlying mechanism and to develop a novel preventive approach for CVD from the perspective of sleep.

Abstract
Background:
Although the aged population is increasing in developed countries, clinical evidence on super-elderly heart failure (HF) patients is scarce. This study determined the characteristics and outcomes of Japanese hospitalized super-elderly HF patients (aged ≥90 years) using a nationwide inpatient database. Methods and Results:
A comprehensive analysis was performed of 447,818 HF patients in the Diagnosis Procedure Combination database who were hospitalized and discharged between January 2010 and March 2018. Among the study population, 243,028 patients (54.3%) were aged ≥80 years and 64,628 patients (14.4%) were aged ≥90 years. The percentage of elderly patients increased over time. Elderly patients were more likely to be female and had a higher New York Heart Association functional class at admission. Invasive and advanced procedures were rarely performed, whereas infectious complications were more common in patients with older age. Length of hospital stay and in-hospital mortality increased with age. Multivariable logistic regression analysis fitted with a generalized estimating equation showed higher in-hospital mortality in patients aged ≥80 and ≥90 years (odds ratios 1.99 and 3.23, respectively) compared with those aged <80 years. Conclusions:
The number of hospitalized super-elderly HF patients has increased, and these patients are associated with worse clinical outcomes. The results of this study may be useful in establishing an optimal management strategy for super-elderly HF patients in the era of HF pandemic.
