Abstract
PURPOSE This study aimed to compare fiducial markers used in CyberKnife treatment in terms of metal artifact intensity observed in CT images and fiducial recognition in the CyberKnife system affected by patient body thickness and type of marker. METHODS Five markers, ACCULOC 0.9 mm × 3 mm, Ball type Gold Anchor (GA) 0.28 mm × 10 mm, 0.28 mm × 20 mm, and novel size GA 0.4 mm × 10 mm, 0.4 mm × 20 mm were evaluated. To evaluate metal artifacts of CT images, two types of CT images of water-equivalent gels with each marker were acquired using Aquilion LB CT scanner, one applied SEMAR (SEMAR-on) and the other did not apply this technique (SEMAR-off). The evaluation metric of artifact intensity (MSD ) which represents a variation of CT values were compared for each marker. Next, 5, 15, and 20 cm thickness of Tough Water (TW) was placed on the gel under the condition of overlapping the vertebral phantom in the Target Locating System, and the live image of each marker was acquired to compare fiducial recognition. RESULTS The mean MSD of SEMAR-off was 78.80, 74.50, 97.25, 83.29, and 149.64 HU for ACCULOC, GA0.28 mm × 10 mm, 20 mm, and 0.40 mm × 10 mm, 20 mm, respectively. In the same manner, that of SEMAR-on was 23.52, 20.26, 26.76, 24.89, and 33.96 HU, respectively. Fiducial recognition decreased in the order of 5, 15, and 20 cm thickness, and GA 0.4 × 20 mm showed the best recognition at thickness of 20 cm TW. CONCLUSIONS We demonstrated the potential to reduce metal artifacts in the CT image to the same level for all the markers we evaluated by applying SEMAR. Additionally, the fiducial recognition of each marker may vary depending on the thickness of the patient's body. Particularly, we showed that GA 0.40 × 20 mm may have more optimal recognition for CyberKnife treatment in cases of high bodily thickness in comparison to the other markers.

Abstract
PURPOSE/OBJECTIVE(S) Towards hypofractionated proton therapy for prostate cancer for improving convenience for patients to receive treatment and improving therapeutic efficacy, image-guided technique with hydrogel spacer solved the late gastrointestinal toxicity, but it is unclear whether acute genitourinary (GU) toxicity is acceptable. The aim of this phase II study was to evaluate the safety and efficacy of hypofractionated image-guided proton therapy (IGPT) with 12 fractions for prostate cancer. MATERIALS/METHODS Eligibility criteria were as follows: (1) histologically confirmed primary prostate cancer; (2) T1-T3bN0M0 staged by (UICC TNM8th); (3) ECOG-PS ≤ 2; (4) age ≥ 20 years; (5) no serious underlying disease or other cancers; (6) technically capable of proton therapy, and (7) written informed consent. Primary endpoint was the ratio of grade 2 or more acute genitourinary toxicity. We used the modified CTCAE grading of grade 2 GU toxicities, in which prescribing two and more types of drugs for dysuria within 3 months of the start of radiation was considered to indicate grade 2 GU toxicity. A phase II trial was planned based on the minimax Simon's two-stage design with a significance level of 0.05 and a power of 90%. The acceptable incidence is considered to be less than 5%, and the unacceptable incidence is considered to be more than 15%. A total of 83 patients is required for completion of the trial (7 patients or fewer). After evaluating the primary endpoint in 83 patients, 217 additional patients were registered and a total of 300 patients were registered in order to further examine the safety and efficacy. The prescribed dose to the isocenter was 51.6 GyRBE in 12 fractions (4 days a week). RESULTS From January 2020 to March 2021, 30, 53, and 217 patients (total 300) were enrolled. The patient characteristics were as follows: median age, 70 (48-83) years; low/intermediate/high risk, 44/132/124. Forty-nine and 38 patients had benign prostatic hyperplasia and diabetes mellitus, respectively. Grade 2 acute GU toxicities were observed in 1, 5 and 13 patients, respectively (total 6.3%). No grade 3 or higher acute GU toxicities were observed. However, urinary retention during IGPT, which was not previously observed, was observed in 3 cases, and temporary urethral catheterization was performed (Grade 2). Most of the acute GU toxicity tended to improve at 1 month after IGPT, and almost improved at 3 months. Mean score deteriorations beyond the minimum clinically important difference threshold (1/2 SD) were observed only at 1 month in the following scales: summary (-6.0), bother (-7.0), and irritative/obstructive (-6.3). CONCLUSION Hypofractionated IGPT with 12 fractions for prostate cancer is well tolerated in acute GU toxicities. Longer follow-up is necessary to evaluate the efficacy and late toxicities. Further investigation of hypofractionated IGPT with 12 fractions for prostate cancer is warranted. Since April 2021, an additional 1000 cases of prospective registration study have been conducted.

Abstract
We aimed to evaluate the impact of systemic autoimmune diseases (SADs) on treatment outcomes and radiation toxicities following stereotactic body radiation therapy (SBRT) for stage I non-small cell lung cancer (NSCLC). We queried an institution-based database on patients with SADs treated with SBRT for lung cancer between 2001 and 2016 (SAD group). Each patient was matched to three controls without SADs. The primary outcomes of interest were the overall survival (OS) and local control rate (LCR). The secondary outcomes were radiation toxicities of grades ≥2 (≥G2). Twelve patients with SADs were matched to 36 controls. The median follow-up duration was 3.6 years. There was a significant intergroup difference in the OS (hazard ratio [HR]: 4.11, 95% confidence incidence [CI]: 1.82−9.27, p < 0.001) and LCR (HR: 15.97, 95% CI: 2.89−88.29, p < 0.001). However, there were no significant intergroup differences in the odds of acute (odds ratio [OR]: 0.38, 95% CI: 0.02−8.91, p = 0.550) and late (OR: 2.20, 95% CI: 0.32−15.10, p = 0.422) ≥G2 radiation pneumonitis. No other ≥G2 toxicities were identified. In conclusion, although radiation toxicities are not enhanced by SADs, SADs are risk factors of poor prognosis following SBRT for stage I NSCLC.

Abstract
Purpose: We aimed to investigate the effects of different multi-leaf
collimator (MLC) speed constraints in volumetric modulated radiotherapy (VMAT)
on the robustness of treatment plans for central lung cancer patients.
Method and Materials: Twenty patients with central lung tumor
who underwent stereotactic body radiotherapy (SBRT) with the VMAT technique at
our hospital were included in this retrospective study. The reference plans were
created with 3 different MLC speed constraints (Plan A: 0.1 cm/deg., Plan B:
0.3 cm/deg., and Plan C: 0.5 cm/deg.) with a 50-Gy/8Fr, planning target volume
(PTV) D95% prescription. In each of these plans, setup errors from 1
to 5 mm were intentionally added in the direction of the central organ at 1-mm
intervals (300 plans [20 cases × 3 MLC speeds × 5 error plans] were created in
total). Each plan was then calculated by the same beam conditions as each
reference plan. The actual average MLC speed and dose difference between the
reference plan and the error-added plan were then calculated and compared among
the 3 MLC speeds. Results: In the reference plans, the actual
average MLC speeds were 0.25 ± 0.04, 0.34 ± 0.07, and 0.39 ± 0.12 cm/deg. for
Plan A, Plan B, and Plan C, respectively (P < .05). For PTV
and OARs, many dose indices tended to improve as the MLC speed increased, while
no significant differences were observed among the 3 MLC speed constraints.
However, in assessments of robustness, no significant differences in dose
difference were observed among the 3 MLC speed constraints for most of the
indices. Conclusions: When necessary, increasing the MLC speed
constraint with a priority on improving the quality of the dose distribution is
an acceptable approach for central lung cancer patients.

Abstract
Background In the resting conditions, narrowing the window of coronary pressure measurements from the whole cardiac cycle to diastole improves diagnostic performance of coronary pressure–derived physiological index. However, whether this also applies to the hyperemic conditions has not yet been thoroughly evaluated. Objectives The purpose of this study was to assess whether diastolic fractional flow reserve (diastolic FFR) has better diagnostic performance in identifying ischemia-causing coronary lesions than conventional FFR in a prospective, multicenter, and independent core laboratory–based environment. Methods In this prospective multicenter registry at 29 Japanese centers, we compared the diagnostic performance of FFR, diastolic FFR, resting distal to aortic coronary pressure (Pd/Pa), and diastolic pressure ratio (dPR) using myocardial perfusion scintigraphy (MPS) as the reference standard in 378 patients with single-vessel coronary disease. Results Inducible myocardial ischemia was found on MPS in the relevant myocardial territory of the target vessel in 85 patients (22%). In the receiver-operating curve analyses, diastolic FFR had comparable area under the curve (AUC) compared with FFR (AUCdiastolic FFR: 0.66; 95% confidence interval [CI]: 0.58-0.73, vs AUCFFR: 0.66; 95% CI: 0.58-0.74, P = 0.624). FFR and diastolic FFR showed significantly larger AUCs than resting Pd/Pa (0.62; 95% CI: 0.54-0.70; P = 0.033 and P = 0.046) but did not show significantly larger AUCs than dPR (0.62; 95% CI: 0.55-0.70; P = 0.102 and P = 0.113). Conclusions Diastolic FFR showed a similar diagnostic performance to FFR as compared with MPS. This result reaffirms the use of FFR as the most accurate invasive physiological lesion assessment.

Abstract
We aimed to assess the predictive value of the modified Glasgow prognostic score (mGPS) in patients with non-small cell lung cancer (NSCLC) who underwent stereotactic body radiation therapy (SBRT). We retrospectively reviewed the records of 207 patients, with a median age of 79 years. The pretreatment mGPS was calculated and categorized as high (mGPS = 1-2) or low (mGPS = 0). The median follow-up duration was 40.7 months. The five-year overall survival (OS), progression-free survival (PFS) and time to progression (TTP) rates were 44.3%, 36% and 54.4%, respectively. Multivariate analysis revealed that mGPS was independently predictive of OS (hazard ratio [HR] 1.67; 95% confidence interval 1.14-2.44: P = 0.009), PFS (HR 1.58; 1.10-2.28: P = 0.014) and TTP (HR 1.66; 1.03-2.68: P = 0.039). Patients who had high mGPS showed significantly worse OS (33.3 vs 64.5 months, P = 0.003) and worse PFS (23.8 vs 39 months, P = 0.008) than those who had low mGPS. The data showed a trend that patients with high mGPS suffered earlier progression compared to those with low mGPS (54.3 vs 88.1 months, P = 0.149). We confirmed that mGPS is independently predictive of prognosis in NSCLC patients treated with SBRT.

Abstract
Background
The circulating concentrations of triglycerides, high density lipoprotein (HDL)-cholesterol, and low density lipoprotein (LDL)-cholesterol have a substantial genetic component. Although previous genome-wide association studies identified various genes and loci related to plasma lipid levels, those studies were conducted in a cross-sectional manner.
Purpose
The purpose of the study was to identify genetic variants that confer susceptibility to hypertriglyceridemia, hypo-HDL-cholesterolemia, and hyper-LDL-cholesterolemia in Japanese. We have now performed longitudinal exome-wide association studies (EWASs) to identify novel loci for dyslipidemia by examining temporal changes in serum lipid profiles.
Methods
Longitudinal EWASs (mean follow-up period, 5 years) for hypertriglyceridemia (2056 case, 3966 controls), hypo-HDL-cholesterolemia (698 cases, 5324 controls), and hyper-LDL-cholesterolemia (2769 cases, 3251 controls) were performed with Illumina Human Exome arrays. The relation of genotypes of 24,691 single nucleotide polymorphisms (SNPs) that passed quality control to dyslipidemia-related traits was examined with the generalized estimating equation (GEE). To compensate for multiple comparisons of genotypes with each of the three conditions, we applied Bonferroni's correction for statistical significance of association. Replication studies with cross-sectional data were performed for hypertriglyceridemia (2685 cases, 4703 controls), hypo-HDL-cholesterolemia (1947 cases, 6146 controls), and hyper-LDL-cholesterolemia (1719 cases, 5833 controls).
Results
Longitudinal EWASs revealed that 30 SNPs were significantly (P<2.03 × 10–6 by GEE) associated with hypertriglyceridemia, 46 SNPs with hypo-HDL-cholesterolemia, and 25 SNPs with hyper-LDL-cholesterolemia. After examination of the relation of identified SNPs to serum lipid profiles, linkage disequilibrium, and results of the previous genome-wide association studies, we newly identified rs74416240 of TCHP, rs925368 of GIT2, rs7969300 of ATXN2, and rs12231744 of NAA25 as a susceptibility loci for hypo-HDL-cholesterolemia; and rs34902660 of SLC17A3 and rs1042127 of CDSN for hyper-LDL-cholesterolemia. These SNPs were not in linkage disequilibrium with those previously reported to be associated with dyslipidemia, indicating independent effects of the SNPs identified in the present study on serum concentrations of HDL-cholesterol or LDL-cholesterol in Japanese. According to allele frequency data from the 1000 Genomes project database, five of the six identified SNPs were monomorphic or rare variants in European populations. In the replication study, all six SNPs were associated with dyslipidemia-related phenotypes.
Conclusion
We have thus identified six novel loci that confer susceptibility to hypo-HDL-cholesterolemia or hyper-LDL-cholesterolemia. Determination of genotypes for these SNPs at these loci may prove informative for assessment of the genetic risk for dyslipidemia in Japanese.

Abstract
Abstract
Background
Clinical congestion is the most dominant feature in patients with acute decompensated heart failure (HF). However, uncertainty exists due to the permutations and combinations of congestion status and decongestion strategies. We aimed to investigate the impact of congestion status and its improvement on 1-year mortality.
Methods
We prospectively included 453 consecutive patients hospitalized for acute decompensated HF between July 2015 and March 2017. Congestion was evaluated using the congestion score which consists of signs and symptoms including dyspnea, fatigue, orthopnea, jugular vein distension, rales, and edema. This score ranges from 0 to 3 for each value, and calculated by summing each score. We assessed this score at admission, day 3, and discharge.
Results
The median age was 81 (interquartile range 75–87) years, and 54.1% of the subjects were male. The 1-year mortality rate was 22.7%. The congestion scores at admission, day 3, and discharge were 10.7±3.9, 3.4±3.5, and 0.3±0.8, respectively. The rate of improvement during the first 3 days was 78% and 46.6% had residual congestion, defined as scores at day 3 ≥3. The score at day 3 and improvement rate during the first 3 days were related to 1-year all-cause mortality (P<0.001). We examined combined predictive values by calculating multivariable-adjusted hazard ratios for associations of residual congestion and improvement rate during the first 3 days (cut-off value 64%); and prognostic variables identified by univariate Cox regression model (age, body mass index, systolic blood pressure, potassium level, albumin level, the prevalence of anemia and hypertension, left ventricular ejection fraction, ischemic etiology, previous HF hospitalization). Residual congestion and lesser improvement (% improvement <64%) were associated with higher relative risk of 1-year all-cause mortality than residual congestion and higher improvement (% improvement ≥64%) [adjusted hazard ratio (aHR) 2.33, 95% CI 1.11–4.91, P=0.025], or resolved congestion (aHR 2.17, 95% CI 1.30–3.63, P=0.003). Similar analysis revealed significant relationship of the score at day 3 and the rate of improvement from admission to day 3 to cardiovascular mortality. Combined predictive values of residual congestion and lesser improvement with adjustment for prognostic variables identified by univariate Cox regression model (age, body mass index, systolic blood pressure, potassium level, albumin level, the prevalence of anemia, reduced eGFR, and hypertension, left ventricular ejection fraction, ischemic etiology, previous HF hospitalization) were higher than those with residual congestion and higher improvement (aHR 3.04, 95% CI 1.15–8.03, P=0.025), or resolved congestion (aHR 3.17, 95% CI 1.65–6.11, P<0.001).
Conclusions
This study suggested that rapid decongestion therapy after hospital admission could be prerequisite to improve 1-year mortality in acute decompensated HF.

Abstract
Abstract
Background
The heritability of Type 2 diabetes mellitus (T2DM) has been estimated to be 50% to 60%. Although genome-wide association studies identified >120 loci that confer susceptibility to T2DM, these studies were commonly conducted in a cross-sectional manner.
Purpose
The purpose of the study was to identify genetic variants that confer susceptibility to T2DM in Japanese. We have now performed longitudinal exome-wide association studies (EWASs) to identify novel loci for T2DM by examining temporal changes in fasting plasma glucose (FPG) level, blood hemoglobin A1c (HbA1c) content, and the prevalence of T2DM.
Methods
Longitudinal EWASs (mean follow-up period, 5 years) were performed with Illumina Human Exome-12 v1.2 DNA Analysis BeadChip or Infinium Exome-24 v1.0 BeadChip arrays and with 6,022 Japanese (755 subjects with T2DM, 5267 controls). The relation of genotypes of 24,579 SNPs that passed quality control to FPG level, blood HbA1c content, or the prevalence of T2DM was examined with the generalized estimating equation (GEE). To compensate for multiple comparisons of genotypes with each of the three parameters, we applied Bonferroni's correction for statistical significance of association.
Results
Longitudinal EWASs (GEE with adjustment for age, sex, body mass index, and smoking) revealed that rs6414624 of EVC (P<2.0×10–16 for T2DM, P=9.1×10–11 for FPG), rs78338345 of GGA3 (P<2.0×10–16 for T2DM, P=4.3×10–9 for FPG), rs10490775 of PTPRG (P<2.0×10–16 for T2DM, P=3.3×10–7 for FPG), and rs61739510 of GLT6D1 (P<2.0×10–16 for T2DM, P=5.8×10–7 for FPG) were significantly associated with the prevalence of T2DM and FPG levels; and rs11558471 in SLC30A8 with FPG level (P=1.8×10–8) and blood HbA1c content (P=1.2×10–7). After examination of the relation of identified SNPs to FPG level and blood HbA1c content, linkage disequilibrium of the SNPs, and results of the previous genome-wide association studies, we identified rs6414624 of EVC and rs78338345 of GGA3 as novel susceptibility loci for T2DM. In the identified SNPs (rs6414624 and rs7833834), FPG level, blood HbA1c content, and the prevalence of T2DM were significantly lower in homozygotes with the minor alleles than in homozygotes with the major alleles or heterozygotes. These results suggest that the minor alleles of rs6414624 and rs78338345 are protective against T2DM in Japanese. According to allele frequency data from the 1000 Genomes Project database, the minor G allele of rs78338345 of GGA3 is specifically distributed in East Asia. This suggests that the minor allele frequency may have increased in East Asian populations after the split of East Asian and non-East Asian populations.
Conclusion
We have newly identified EVC and GGA3 as susceptibility loci for T2DM in Japanese. Determination of genotypes for these SNPs at these loci may prove informative for assessment of the genetic risk for T2DM in Japanese.

Abstract
Abstract
Background
Early-onset cardiovascular and renal diseases have a strong genetic component.
Purpose
To identify genetic variants that confer susceptibility to early-onset myocardial infarction (MI), hypertension, or chronic kidney disease (CKD) in Japanese. We have performed exome-wide association studies (EWASs) in subjects with early-onset forms of these diseases.
Methods
A total of 8093 individuals aged ≤65 years was enrolled in the study. The EWASs for MI, hypertension, and CKD were conducted with 6926 subjects (1152 cases, 5774 controls), 8080 subjects (3444 cases, 4636 controls), and 2556 subjects (1051 cases, 1505 controls), respectively. Genotyping of single nucleotide polymorphisms (SNPs) was performed with Illumina Human Exome-12 DNA Analysis BeadChip or Infinium Exome-24 BeadChip arrays. The relation of allele frequencies for 31,245, 31,276, or 31,514 SNPs that passed quality control to MI, hypertension, and CKD, respectively, was examined with Fisher's exact test. Bonferroni's correction for statistical significance of association was applied to compensate for multiple comparisons of genotypes with MI, hypertension, or CKD.
Results
The EWASs of allele frequencies revealed that 25, 11, and 11 SNPs were significantly associated with MI (P<1.60 × 10–6), hypertension (P<1.60 × 10–6), or CKD (P<1.59 × 10–6), respectively. Multivariable logistic regression analysis with adjustment for covariates showed that all 25, 11, and 11 SNPs were significantly related to MI (P<0.0005), hypertension (P<0.0011), or CKD (P<0.0011), respectively. After examination of results from previous genome-wide association studies and linkage disequilibrium of the identified SNPs, we newly identified 11 loci (TMOD4, COL6A3, ADGRL3-CXCL8-MARCH1, OR52E4, TCHP-GIT2, CCDC63, 12q24.1, OAS3, PLCB2-VPS33B, GOSR2, ZNF77), six loci (MOB3C-TMOD4, COL6A3, COL6A5, CXCL8-MARCH1, NFKBIL1-6p21.3-NCR3, PLCB2-VPS33B), and seven loci (MOB3C-TMOD4, COL6A3, COL6A5, ADGRL3-CXCL8-MARCH1, MUC17, PLCB2-VPS33B, ZNF77) that were significantly associated with MI, hypertension, or CKD, respectively. Furthermore, six genes (TMOD4, COL6A3, CXCL8, MARCH1, PLCB2, VPS33B) were significantly associated with MI, hypertension, and CKD; two genes (ADGRL3, ZNF77) with MI and CKD; and two genes (COL6A5, MOB3C) with hypertension and CKD. Network analysis showed that the 13, 10, or 11 genes associated with MI, hypertension, or CKD, respectively, in the present study had direct or indirect interactions with the corresponding sets of 50 genes previously shown to be associated with MI, hypertension, or CKD.
Conclusion
We newly identified 13 loci (MOB3C-TMOD4, COL6A3, ADGRL3-CXCL8-MARCH1, OR52E4, TCHP-GIT2, CCDC63, 12q24.1, OAS3, PLCB2-VPS33B, ZNF77, COL6A5, NFKBIL1-NCR3, MUC17) that confer susceptibility to early-onset MI, hypertension, or CKD. Determination of genotypes for the SNPs at these loci may prove informative for assessment of the genetic risk for MI, hypertension, or CKD in Japanese.

Abstract
Abstract
Background
Along with an aging society, the global burden of heart failure (HF) is evident in Japan. Recent reports showed that malnutrition is one of the frequent comorbidity in patients with HF, and this grievous issue is related to worsening prognosis in such subjects. There are many screening tools of nutrition risks, however, feasible indexes or strategies for evaluating nutrition risk in patients with HF remain to be identified definitively.
Purpose
The purpose of the present study was to examine the effectiveness of various nutrition indexes on 3-year mortality in hospitalized acute HF patients.
Methods
The study population comprised a total of 817 individuals who were hospitalized for acute HF between November 2009 and December 2015, and was followed up for 3 years. All the previously established objective nutritional indexes [The controlling nutritional status (CONUT) score, geriatric nutritional risk index (GNRI), and subjective global assessment (SGA)] were evaluated at the time of hospital admission. Malnutrition status of each index was defined as CONUT score ≥5, GNRI <91, or SGA (B and C), respectively. We evaluated combined predictive values of these indexes for 3-year mortality by Cox regression model, and calculated the net reclassification improvement (NRI) and the integrated discrimination improvement (IDI).
Results
The median age was 79 (interquartile range 70–85) years, and 55.7% of the subjects were male. The frequency of malnutrition was 18.1% in CONUT score, 31.9% in GNRI, and 25.9% in SGA. The rate of 3-year mortality was 32.2%. All indexes were related to the occurrence of 3-year mortality by univariate analyses (P<0.001). We examined combined predictive values by calculating multivariable-adjusted hazard ratios (aHR) and 95% confidence intervals (CI) for associations of malnutrition by these 3 indexes and prognostic variables identified by multivariable Cox regression model (age, body mass index, systolic blood pressure, reduced eGFR, albumin, and prior HF hospitalization). Malnutrition of all 3 indexes (5.6% of the subjects) was associated with higher relative risk of 3-year mortality than well-nutrition (aHR 1.90; 95% CI 1.07–3.35, P=0.028), or malnutrition of any 1 index (aHR 1.95; 95% CI 1.18–3.21, P=0.009). Next, we individually included each value into a reference model (age, body mass index, reduced eGFR, albumin, prior HF hospitalization, and ischemic etiology by multivariable logistic regression analysis with P<0.05). SGA was superior according to comprehensive discrimination, calibration, and reclassification analysis (NRI 0.212, P=0.003; IDI 0.005, P=0.029). Similar analysis with other indexes (CONUT score or GNRI) revealed no improvement.
Conclusion
Our present results suggest that simultaneous addition of CONUT, GNRI, and SGA seems useful for predicting long-term mortality in acute HF. In addition, nutritional screening with SGA independently improves mortality risk stratification.

Abstract
Abstract
Background
Acidosis or lactate accumulation is frequently observed in patients with acute decompensated heart failure (ADHF). Although each value can be easily obtained and evaluated by arterial blood sampling, sampling to all patients is difficult in daily clinical practice. Therefore, the prognostic impact of acidosis or lactate accumulation on this condition remains to be identified definitively.
Purpose
The purpose of the study was to verify the effectiveness of selective arterial blood sampling at emergency department in patients with ADHF by evaluating an association with in-hospital mortality.
Methods
A total of 917 consecutive patients with ADHF from April 2012 to March 2017 were enrolled. We compared baseline characteristics and in-hospital mortality between patients with or without arterial blood sampling. Patients performed blood sampling were assigned to four groups according to the presence or absence of acidosis (PH <7.35) and lactate accumulation (>2.0 mmol/L), and predictive value of acidosis and/or lactate accumulation for in-hospital mortality was calculated by multivariable logistic regression analysis.
Results
Of all patients, 689 patients (75.1%) underwent blood sampling. Systolic blood pressure and heart rate at hospital arrival, use of emergency medical service, previous heart failure hospitalization, New York Heart Association classification grade IV, presence of jugular vein distention, and the prevalence of hypertension and dementia, were significantly different between the two groups (P<0.05). There was no difference in the occurrence of in-hospital mortality between patients with or without blood sampling (9.3% in patients with blood sampling versus 9.2% in those without blood sampling, respectively; P=0.972). In 689 patients who underwent blood sampling, we examined combined predictive value of acidosis and/or lactate accumulation for in-hospital mortality by multivariable logistic regression analysis with adjustments for covariates with P<0.05 (age, systolic blood pressure at hospital arrival, left ventricular ejection fraction, and cold profile), and showed that acidosis with lactate accumulation [adjusted odds ratio (OR) 3.30, 95% confidence interval (CI) 1.22–8.93, P=0.019], acidosis without lactate accumulation (adjusted OR 4.06, 95% CI 1.12–14.7, P=0.033), lactate accumulation without acidosis (adjusted OR 2.69, 95% CI 1.14–6.33, P=0.024) were significantly (P<0.05) associated with in-hospital mortality. Our results indicated that patients presenting acidosis without lactate accumulation revealed the highest in-hospital mortality among the four groups.
Conclusion
Arterial blood sampling at emergency department could be beneficial for stratifying high risk patients with ADHF. Furthermore, routine blood sampling could be allowed in patients with ADHF if we can secure safety.

Abstract
Abstract
Background
Given that substantial genetic components have been shown in ischemic stroke, intracerebral hemorrhage (ICH), and subarachnoid hemorrhage (SAH), a heritability may be higher in early-onset than late-onset individuals with these conditions. Although genome-wide association studies have identified various genes and loci significantly associated with ischemic stroke, ICH, or intracranial aneurysm mainly in European ancestry populations, genetic variants that contribute to susceptibility to these disorders in Japanese individuals remain to be identified definitively.
Purpose
The purpose of the study was to identify genetic variants that confer susceptibility to ischemic stroke, ICH, or SAH in Japanese. We have now performed exome-wide association studies (EWASs) in early-onset subjects with these conditions and corresponding controls.
Methods
A total of 6649 individuals aged ≤65 years were examined. For the EWAS of ischemic or hemorrhagic stroke, 6224 individuals (450 subjects with ischemic stroke, 5774 controls) or 6179 individuals (261 subjects with ICH, 176 subjects with SAH, 5742 controls), respectively, were examined. EWASs were performed with the use of Illumina Human Exome-12 v1.2 DNA Analysis BeadChip or Infinium Exome-24 v1.0 BeadChip. To compensate for multiple comparisons of allele frequencies with ischemic stroke, ICH, or SAH, we applied a false discovery rate (FDR) of <0.05 for statistical significance of association.
Results
The relation of allele frequencies of 31,245 single nucleotide polymorphisms (SNPs) that passed quality control to ischemic stroke was examined with Fisher's exact test, and 31 SNPs were significantly (FDR <0.05) associated with ischemic stroke. The relation of allele frequencies of 31,253 or 30,970 SNPs to ICH or SAH, respectively, was examined with Fisher's exact test, and six or two SNPs were significantly (FDR <0.05) associated with ICH or SAH, respectively. Multivariable logistic regression analysis with adjustment for age, sex, and the prevalence of hypertension and diabetes mellitus revealed that 12 SNPs were significantly [P <0.0004 (Bonferroni's correction, 0.05/124)] related to ischemic stroke. Similar analysis with adjustment for age, sex, and the prevalence of hypertension revealed that six or two SNPs were significantly [P <0.0016 (0.05/32)] related to ICH or SAH, respectively. After examination of linkage disequilibrium of identified SNPs and results of previous genome-wide association studies, we have newly identified HHIPL2, CTNNA3, LOC643770, UTP20, and TRIB3 as susceptibility loci for ischemic stroke, DNTTIP2 and FAM205A as susceptibility loci for ICH, and FAM160A1 and OR52E4 as such loci for SAH.
Conclusion
We have thus newly identified nine genes that confer susceptibility to early-onset ischemic stroke, ICH, or SAH. Determination of genotypes for the SNPs in these genes may prove informative for assessment of the genetic risk for ischemic stroke, ICH, or SAH in Japanese.

Abstract
Abstract
Background
The prevalence of heart failure (HF) in the elderly is steadily increasing, therefore, the prudent care and treatment according to individual's characteristics, comorbidities, or prognosis, should be prerequisite. Although cohabitations status in each elderly patient is different, an association of this condition with long-term prognosis remains to be identified definitively in Japan.
Purpose
The purpose of the present study was to examine the prognostic impact of cohabitation status on 3-year mortality among hospitalized acute HF patients.
Methods
The study population comprised a total of 817 individuals who were hospitalized for acute HF between November 2009 and December 2015, and was followed up for 3 years. We classified patients into three groups (cohabitation with spouse, cohabitation with another generation, and living alone). We evaluated relative predictive values between these three groups for 3-year mortality by Cox regression model.
Results
The median age was 79 (interquartile range 70–85) years, and 55.7% of the subjects were male. Median length of hospital stay was 16 (interquartile range 11–23) days. The distribution of three groups was cohabitation with spouse (50.9%), cohabitation with another generation (28.5%), and living alone (20.6%). The overall rate of 3-year mortality was 32.2% (n=263), 31.5% (n=131) in cohabitation with spouse, 38.2% (n=89) in cohabitation with another generation, and 25.6% (n=43) in living alone. Cohabitation with another generation was significantly related to the occurrence of 3-year mortality by univariate analysis (P<0.001). Age (84 years vs. 77 years), the frequency of female (69.1% vs. 33.4%), left ventricular ejection fraction (52.7% vs. 47.5%) were significantly greater, whereas body mass index (21.2 vs. 22.6), smoking status (27.0% vs. 53.4%), ischemic etiology (27.5% vs. 35.6%), and the prevalence of type 2 diabetes mellitus (32.2% vs. 41.4%) and atrial fibrillation (20.6% vs. 29.8%) were significantly (P<0.05) smaller in cohabitation with another generation than others. The ratio of home return and optimal medical therapy were similar between the 2 groups. Cohabitation with another generation was associated with higher relative risk of 3-year mortality than living alone [Hazard Ratio (HR) 1.65; 95% Confidence Interval (CI) 1.15–2.38, P=0.007], or cohabitation with spouse (HR 1.46; 95% CI 1.12–1.92, P=0.006). Multivariable Cox regression model, with adjustment for age, albumin, brain natriuretic peptide, and prior HF hospitalization, revealed that cohabitation with another generation was no longer significant.
Conclusion
Our present results suggest that cohabitation status affected on long-term prognosis in patients with HF, especially cohabitation with another generation posed as worst predictor. We should pay more attention to social factors including cohabitation status in the clinical practice.

Abstract
Abstract
Background
Several studies have proved that both poor nutrition (PN) and Frail are associated with poor prognosis among heart failure patients. However, it has not been fully revealed whether PN and frail could have impact on prognosis accumulatively.
Purpose
The purpose of the present study was to evaluate the impact of nutritional and Frailty status on 1-year mortality among hospitalized patients with acute decompensated heart failure (ADHF).
Methods
Study subjects comprised of 315 hospitalized patients with ADHF. To evaluate the nutritional and Frailty status, we calculated the controlling nutritional status (CONUT) score and the Study of Osteoporotic Fractures (SOF) index at hospital admission. PN and Frailty were defined as the CONUT score ≥5 and SOF index ≥2, respectively.
Results
z Sixty-nine subjects (21.9%) were died within 1-year. PN and Frailty were observed in 33.3% and 55.6% of study subjects, respectively. Both PN and Frailty were similarly related to the 1-year mortality by univariate cox regression analysis (Hazard Ratio (HR) 2.43, 95% confidence interval (CI) 1.51–3.91, p=0.0003: HR 3.13, 95% CI 1.83–5.66, p<0.0001, respectively).
Study subjects were classified into 4 groups according to the nutritional and frailty status: control (normal nutrition without Frailty, n=110), PN alone (PN without Frailty, n=30), Frailty alone (Frailty without PN, n=100), and PN + Frailty (PN with Frailty, n=75). The Kaplan-Meier event curves for 1-year all-cause mortality illustrated that subjects with PN + Frailty had a significantly higher mortality than in subjects with control, PN alone and Frailty alone (log rank p=0.0001, 0.0180, 0.0070, respectively).
As well as, cox regression analysis revealed that PN + Frailty showed significantly higher mortality than control, PN alone and Frailty alone. (HR 5.33, 95% CI 2.75–11.1, p<0.0001: HR 2.99, 95% CI 1.26–8.78, p=0.011: HR 2.07, 95% CI 1.21–3.61, p=0.008, respectively). Moreover, multivariate cox regression analysis also revealed that PN with Frailty was independently associated with 1-year mortality even after adjustment for age, body mass index, systolic blood pressure, and chronic kidney disease. (HR 3.40, 95% CI 1.69–7.32, adjusted p<0.001)
Kaplan-Meier curve for 1year mortality
Conclusions
The combination assessment consisted with nutrition and frailty could identify poor prognosis patients with ADHF.

Abstract
Abstract
Background
The circulating concentrations of triglycerides, high density lipoprotein (HDL)–cholesterol, and low density lipoprotein (LDL)–cholesterol have a substantial genetic component, and the heritability of early-onset dyslipidemia is expected to be higher than that of late-onset forms of this condition.
Purpose
To identify genetic variants that confer susceptibility to early-onset hypertriglyceridemia, hypo–HDL-cholesterolemia, and hyper–LDL-cholesterolemia in Japanese. We have now performed exome-wide association studies (EWASs) for early-onset forms of these conditions.
Methods
A total of 8073 individuals aged ≤65 years was enrolled in the study. The EWASs for hypertriglyceridemia (2664 cases, 5294 controls), hypo–HDL-cholesterolemia (974 cases, 7085 controls), and hyper–LDL-cholesterolemia (2911 cases, 5111 controls) were performed with Illumina Human Exome-12 v1.2 DNA Analysis BeadChip or Infinium Exome-24 v1.0 BeadChip arrays. The relation of allele frequencies for 31,198, 31,133, or 31,175 single nucleotide polymorphisms (SNPs) that passed quality control to hypertriglyceridemia, hypo–HDL-cholesterolemia, or hyper–LDL-cholesterolemia, respectively, was examined with Fisher's exact test. To compensate for multiple comparisons of genotypes with each of the three conditions, we applied Bonferroni's correction for statistical significance of association.
Results
The EWASs of allele frequencies revealed that 25, 28, or 65 SNPs were significantly associated with hypertriglyceridemia (P<1.60 × 10–6), hypo–HDL-cholesterolemia (P<1.61 × 10–6), or hyper–LDL-cholesterolemia (P<1.60 × 10–6), respectively. Multivariable logistic regression analysis with adjustment for age and sex showed that all 25, 28, or 65 of these SNPs were significantly related to hypertriglyceridemia (P<0.0005), hypo–HDL-cholesterolemia (P<0.0004), or hyper–LDL-cholesterolemia (P<0.0002), respectively. After examination of the relation of the identified SNPs to serum concentrations of triglycerides, HDL-cholesterol, or LDL-cholesterol, linkage disequilibrium of the SNPs, and results of previous genome-wide association studies, we newly identified chromosomal region 19p12 as a susceptibility locus for hypertriglyceridemia, eight loci (MOB3C-TMOD4, LPGAT1, EHD3, COL6A3, ZNF860-CACNA1D, COL6A5, DCLRE1C, ZNF77) for hypo–HDL-cholesterolemia, and three loci (KIAA0319-FAM65B, UBD, LOC105375015) for hyper–LDL-cholesterolemia. Network analysis showed that the 10 or three genes associated with hypo-HDL-cholesterolemia or hyper-LDL-cholesterolemia, respectively, had direct or indirect interactions with the 50 genes previously shown to be associated with dyslipidemia.
Conclusion
We have thus identified 12 novel loci that confer susceptibility to early-onset dyslipidemia. Determination of genotypes for the SNPs at these loci may prove informative for assessment of the genetic risk for hypertriglyceridemia, hypo–HDL-cholesterolemia, or hyper–LDL-cholesterolemia in Japanese.

Abstract
Abstract
Background
Given that early-onset type 2 diabetes mellitus (T2DM), metabolic syndrome, and hyperuricemia have been shown to have strong genetic components, statistical power of a genetic association study may be increased by focusing on early-onset subjects with these conditions. Although genome-wide association studies have identified various genes and loci significantly associated with T2DM, metabolic syndrome, and hyperuricemia, genetic variants that contribute to predisposition to these conditions in Japanese individuals remain to be identified definitively.
Purpose
The purpose of the study was to identify genetic variants that confer susceptibility to early-onset T2DM, metabolic syndrome, or hyperuricemia in Japanese. We have now performed exome-wide association studies (EWASs) for early-onset subjects with T2DM, metabolic syndrome, or hyperuricemia and corresponding controls.
Methods
A total of 8102 individuals aged ≤65 years was enrolled in the study. The EWAS for T2DM was performed with 7407 subjects (1696 cases, 5711 controls), that for metabolic syndrome with 4215 subjects (2296 cases, 1919 controls), and that for hyperuricemia with 7919 subjects (1365 cases, 6554 controls). Single nucleotide polymorphisms (SNPs) were genotyped with Illumina Human Exome-12 DNA Analysis BeadChip or Infinium Exome-24 BeadChip arrays. The relation of allele frequencies for 31,210, 31,521, or 31,142 SNPs that passed quality control to T2DM, metabolic syndrome, or hyperuricemia, respectively, was examined with Fisher's exact test. To compensate for multiple comparisons of genotypes with T2DM, metabolic syndrome, or hyperuricemia, we applied Bonferroni's correction for statistical significance of association.
Results
The EWAS of allele frequencies revealed that four, six, or nine SNPs were significantly associated with T2DM (P<1.60 × 10–6), metabolic syndrome (P<1.59 × 10–6), or hyperuricemia (P<1.61 × 10–6), respectively. Multivariable logistic regression analysis with adjustment for age and sex revealed that three, six, or nine SNPs were significantly related to T2DM (P<0.0031), metabolic syndrome (P<0.0021), or hyperuricemia (P<0.0014). After examination of the association of identified SNPs to T2DM-, metabolic syndrome-, or hyperuricemia-related traits, linkage disequilibrium of the SNPs, and results of previous genome-wide association studies, we have newly identified ZNF860 and OR4F6 as susceptibility loci for T2DM, OR52E4 and OR4F6 for metabolic syndrome, and HERPUD2 for hyperuricemia.
Conclusion
Given that OR4F6 was significantly associated with both T2DM and metabolic syndrome, we thus newly identified four genes (ZNF860, OR4F6, OR52E4, HERPUD2) that confer susceptibility to early-onset T2DM, metabolic syndrome, or hyperuricemia. Determination of genotypes for the SNPs in these genes may prove informative for assessment of the genetic risk for T2DM, metabolic syndrome, or hyperuricemia in Japanese.

Abstract
Abstract
Background
Early-onset coronary artery disease (CAD) has a strong genetic component. Although genome-wide association studies have identified various genes and loci significantly associated with CAD mainly in European ancestry populations, genetic variants that contribute to susceptibility to this condition in Japanese individuals remain to be identified definitively.
Purpose
The purpose of the study was to identify genetic variants that confer susceptibility to early-onset CAD in Japanese. We have now performed exome-wide association studies (EWASs) in subjects with early-onset CAD and controls.
Methods
A total of 7256 individuals aged ≤65 years was enrolled in the study. The EWAS was conducted with 1482 subjects with CAD and 5774 controls. Genotyping of single nucleotide polymorphisms (SNPs) was performed with Illumina Human Exome-12 DNA Analysis BeadChip or Infinium Exome-24 BeadChip arrays. The relation of allele frequencies for 31,465 SNPs that passed quality control to CAD was examined with Fisher's exact test. To compensate for multiple comparisons of allele frequencies with CAD, we applied a false discovery rate (FDR) of <0.05 for statistical significance of association.
Results
The relation of allele frequencies for 31,465 SNPs to CAD with the use of Fisher's exact test showed that 170 SNPs were significantly (FDR <0.05) associated with CAD. Multivariable logistic regression analysis with adjustment for age, sex, and the prevalence of hypertension, diabetes mellitus, and dyslipidemia revealed that 162 SNPs were significantly (P<0.05) related to CAD. A stepwise forward selection procedure was performed to examine the effects of genotypes for the 162 SNPs on CAD. The 54 SNPs were significant (P<0.05) and independent [coefficient of determination (R2), 0.0008 to 0.0297] determinants of CAD. These SNPs together accounted for 15.5% of the cause of CAD. After examination of results from previous genome-wide association studies and linkage disequilibrium of the identified SNPs, we newly identified 21 genes (RNF2, YEATS2, USP45, ITGB8, TNS3, FAM170B-AS1, PRKG1, BTRC, MKI67, STIM1, OR52E4, KIAA1551, MON2, PLUT, LINC00354, TRPM1, ADAT1, KRT27, LIPE, GFY, EIF3L) and five chromosomal regions (2p13, 4q31.2, 5q12, 13q34, 20q13.2) that were significantly associated with CAD. Gene ontology analysis showed that various biological functions were predicted in the 18 genes identified in the present study. The network analysis revealed that the 18 genes had potential direct or indirect interactions with the 30 genes previously shown to be associated with CAD or with the 228 genes identified in previous genome-wide association studies of CAD.
Conclusion
We have newly identified 26 loci that confer susceptibility to CAD. Determination of genotypes for the SNPs at these loci may prove informative for assessment of the genetic risk for CAD in Japanese.

Abstract
Rose hip is the fruit of the rose plant, which is widely used in food, cosmetics and as a traditional medicine. Therefore, rose hip is considered safe and has a sufficient history of consumption as food. However, few studies have reported on the safety of rose hip extracts in toxicological analyses. Thus, to evaluate the safety of rosehip polyphenol MJ (RHPMJ), an aqueous ethanol extract standardized with the trans-tiliroside content, we performed genotoxicity and 90-day repeated oral dose toxicity studies in compliance with the Organisation for Economic Co-operation and Development-Good Laboratory Practice. RHPMJ did not induce gene mutations in reverse mutation tests of Salmonella typhimurium TA98, TA100, TA1535, TA1537 and Escherichia coli WP2 uvrA strains and did not induce chromosomal aberrations in cultured Chinese hamster lung (CHL/IU) cells. Moreover, micronucleus tests using rat bone marrow showed RHPMJ had no micronucleus-inducing potential. Finally, 90-day repeated oral dose toxicity studies (100–1000 mg/kg) in male and female rats showed no treatment-related toxicity in rats. These data indicate that the RHPMJ had no genotoxicity and a no-observed-adverse-effect level greater than 1000 mg/kg in rats.

Abstract
Background Treatment of primary renal cell carcinoma using radiotherapy with curative intent is rare, because renal cell carcinoma is generally regarded as a radiation-resistant tumor. Recently, stereotactic body radiation therapy has been radically applied for cancers in various organs including renal cell carcinoma. However, there were few reports describing pathological changes of renal cell carcinoma post stereotactic body radiation therapy. This is the first report we are aware of documenting late histological effects of stereotactic body radiation therapy on renal cell carcinoma and surrounding normal tissue. Case presentation A right renal tumor was identified in a Japanese 70-year-old man on follow-up computed tomography for his chronic hepatitis. T1N0M0 renal cell carcinoma was clinically diagnosed as the tumor was 3 cm in diameter and well-enhanced with intravenously infused contrast material in the arterial phase on computed tomography. No metastases in regional lymph nodes or distant sites were evident. Stereotactic body radiation therapy was selected as an alternative therapy to surgery because of his poor liver function. A total dose of 60 Gy in 10 fractions over 12 days was delivered using a 10-megavolt X-ray. The renal tumor gradually decreased in size and partial response had been achieved at 2 years after completing stereotactic body radiation therapy. Hepatocellular carcinoma was identified during follow-up in the patient and he died of progression of hepatocellular carcinoma with hepatic failure 2.5 years after completing stereotactic body radiation therapy. Autopsy was done and it showed almost complete necrosis of tumor tissues with a small amount of viable renal carcinoma cells. These pathological findings suggested marked effects of stereotactic body radiation therapy on clear cell renal cell carcinoma. Conclusion Our case demonstrates a good pathological response with small foci of remnant viable cancer cells after stereotactic body radiation therapy of 60Gy in 10 fractions for small renal cell carcinoma. Although further experiences and longer follow-up are mandatory to conclude the optimal treatment schedule and efficacy of stereotactic body radiation therapy for renal cell carcinoma, stereotactic body radiation therapy may represent a novel less-invasive option for the treatment of primary renal cell carcinoma.

Abstract
PURPOSE To investigate prognostic and risk factors for recurrence after stereotactic body radiation therapy (SBRT) in patients with stage I non-small cell lung carcinoma (NSCLC), focusing on dual time point [18]F-fluorodeoxyglucose positron emission tomography (FDG PET). MATERIALS AND METHODS We prospectively evaluated 57 patients with stage I NSCLC (45 T1N0M0 and 12 T2N0M0) who had undergone pretreatment FDG-PET/CT and were subsequently treated with SBRT. All patients received a whole-body PET/CT scan at 60 min and a whole-lung at 120 min after the injection. The maximum standardized uptake value (SUV) and retention index (RI) of the lesions were calculated. Local recurrence, regional lymph node metastasis, distant metastasis, and the recurrence pattern were evaluated. Cox proportional hazard regression analyses were performed to evaluate prognostic factors or risk factors of recurrence. RESULTS During the median follow-up period of 27 months, local recurrence, regional lymph node metastasis, and distant metastasis were seen in 17 (30%), 12 (21%), and 17 (30%) of the 57 patients, respectively. The 3-year overall survival rate was 63.4%. SUVmax did not affect any recurrence, DFS, OS, or CSS. RI significantly predicted higher distant metastasis (HR 47.546, p=0.026). In contrast, RI tended to predict lower local recurrence (HR 0.175, p=0.246) and regional lymph node metastasis (HR 0.109, p=0.115). CONCLUSIONS SUVmax at staging FDG-PET does not predict any recurrence, DFS, OS or CSS. In contrast, higher RI predicts higher distant metastasis and tended to predict lower local or regional lymph node metastasis.

Abstract
AIMS We previously showed that the C→T polymorphism (rs6929846) of BTN2A1 was significantly associated with myocardial infarction in Japanese individuals by a genome-wide association study. Given that diabetes mellitus is an important risk factor for myocardial infarction, the association of rs6929846 of BTN2A1 with myocardial infarction might be attributable, at least in part, to its effect on susceptibility to diabetes. The purpose of this study was to examine the relation of rs6929846 of BTN2A1 to Type 2 diabetes mellitus. METHODS A total of 8650 Japanese individuals from two independent subject panels were examined: Panel A comprised 1141 individuals with Type 2 diabetes and 3161 control subjects and panel B comprised 1664 individuals with Type 2 diabetes and 2684 control subjects. RESULTS The chi-square test revealed that rs6929846 of BTN2A1 was significantly related to the prevalence of Type 2 diabetes in subject panel A (P = 0.0002) and subject panel B (P=0.006). Multivariable logistic regression analysis with adjustment for age, sex, body mass index and smoking status revealed that rs6929846 was significantly associated with Type 2 diabetes (P = 0.0006; odds ratio 1.25) in all individuals, with the T allele representing a risk factor for this condition. Multiple regression analysis with adjustment for age, sex and body mass index revealed that rs6929846 was significantly (P=0.04) related to blood glycosylated haemoglobin content in control subjects. CONCLUSIONS BTN2A1 may be a susceptibility gene for Type 2 diabetes in Japanese individuals.

Abstract
BACKGROUND We previously showed that the C→T polymorphism (rs6929846) in butyrophilin, subfamily 2, member A1 gene (BTN2A1) was associated with myocardial infarction in Japanese individuals. Given that hypertension is a major risk factor for myocardial infarction, the association of rs6929846 of BTN2A1 with myocardial infarction might be attributable, at least in part, to its effect on susceptibility to hypertension. We have thus examined the relation of rs6929846 of BTN2A1 to hypertension in Japanese individuals. METHODS A total of 8,567 Japanese individuals from two independent subject panels were examined: Subject panels A and B comprised 2,317 hypertensive individuals and 1,933 controls, and 2,911 hypertensive individuals and 1,406 controls, respectively. The genotype of rs6929846 was determined by a method that combines the PCR and sequence-specific oligonucleotide probes with suspension array technology. RESULTS Multivariable logistic regression analysis with adjustment for covariates revealed that rs6929846 of BTN2A1 was significantly associated with hypertension in subject panel A (P = 2.6 × 10(-6); odds ratio, 1.69) and in subject panel B (P = 0.0284; odds ratio, 1.24), with the T allele representing a risk factor for hypertension. The rs6929846 was associated with systolic blood pressure (BP) in subject panels A (P = 0.0063) and B (P = 0.0115) and with diastolic BP in subject panel B (P = 0.0323), with the T allele being related to high BP. CONCLUSIONS BTN2A1 may be a susceptibility gene for hypertension in Japanese individuals. Determination of genotype for this polymorphism may prove informative for assessment of the genetic risk for hypertension.
