Diagnostic strategies for symptomatic transthyretin (ATTR) cardiac amyloidosis showing typical morphological features such as increased ventricular wall thickness and myocardial injury such as an elevation in serum troponin T level have been established, but those for subclinical cardiac amyloidosis are limited. In the era when effective therapies to suppress/delay progression of ATTR cardiac amyloidosis are available, early detection of cardiac involvement plays a crucial role in appropriate decision-making for treatment in TTR mutation carriers who have a family history of heart failure and death due to ATTR amyloidosis. Findings of three cases with known pathogenic transthyretin (TTR) mutations (p.Ser70Arg, p.Phe53Val, and p.Val50Met) and family histories of death for amyloidosis were presented. Two cases were asymptomatic, and a case carrying p.Phe53Val had gastrointestinal symptoms and autonomic neuropathy. Levels of plasma N-terminal fragment of pro-B-type natriuretic peptide and troponin T were within normal ranges in all cases, but results of cardiac magnetic resonance (CMR) and bone scintigraphy clearly revealed the presence of cardiac involvement in all cases, even in a case without echocardiographic abnormalities including left ventricular hypertrophy and relative apical sparing of longitudinal strain shown by two-dimensional speckle-tracking echocardiography. Electrocardiography revealed modest abnormalities including reduced R wave amplitude in V2 and a trend toward left axis deviation in all cases. In conclusion, CMR, bone scintigraphy, and electrocardiography are useful for early detection of ATTR cardiac amyloidosis in TTR mutation carriers. The role of comprehensive cardiac assessment in the early detection of cardiac amyloidosis in TTR mutation carriers is discussed.

Previous studies suggested that taurine (2-aminoethanesulfonic acid) administration enhances glucose uptake, one of the rate-limiting factors for glycogen synthesis. In this study, we investigated the effects of post-exercise taurine administration on glycogen repletion in skeletal muscle in ICR mice. In experiment 1, we orally administered either taurine (0.5 mg/g body weight) solution or physiological saline immediately after treadmill running at 25 m/min for 90 min. The serum free fatty acid (FFA) concentration at 60 min after the exercise was significantly higher in the taurine-treated group compared with the control group (p < 0.05). At 120 min after the exercise, the tibialis anterior muscle glycogen concentration in the taurine-treated group was significantly higher than that in the control group (p < 0.05). In experiment 2, we orally administered either glucose (1 mg/g body weight) solution or glucose solution containing taurine immediately after and at 60 min after the exercise. The area under the curve (AUC) for blood glucose concentration from 0 to 60 min after the exercise was significantly smaller in the taurine-treated group compared with the control group (p < 0.01). Our results show that post-exercise taurine administration enhances glycogen repletion in skeletal muscle. Higher skeletal muscle glycogen concentration by taurine administration may be partly due to the acceleration of glucose uptake. In addition, as the elevation of blood FFA level leads to an increase in fat oxidation, it is possible that a higher serum FFA concentration by taurine treatment is related to the sparing of carbohydrate for glycogen repletion.

Background:Smoking cessation reduces the risk of cardiovascular disease (CVD) and improves clinical outcomes in public health. We studied the effect of smoking cessation on high-density lipoprotein (HDL) functionality.Methods and Results:We randomly treated 32 smokers with varenicline or a transdermal nicotine patch as part of a 12-week smoking cessation program (The VN-SEESAW Study). The plasma lipid profiles, plasma and HDL malondialdehyde (MDA) levels, HDL subfractions as analyzed by capillary isotachophoresis, cholesterol efflux capacity, and antiinflammatory activity of HDL were measured before and after the anti-smoking intervention. After smoking cessation, HDL-C, apoA-I levels and HDL subfractions were not significantly different from the respective baseline values. However, cholesterol efflux capacity and the HDL inflammatory index (HII) were significantly improved after smoking cessation. The changes in both parameters (%∆ cholesterol efflux capacity and ∆HII) were also significantly improved in the successful smoking cessation group compared with the unsuccessful group. The changes in cholesterol efflux capacity and HII also correlated with those in end-expiratory CO concentration and MDA in HDL, respectively.Conclusions:Our findings indicate that smoking cessation leads to improved HDL functionality, increased cholesterol efflux capacity and decreased HII, without changing HDL-C or apoA-I levels or HDL subfractions. This may be one of the mechanisms by which smoking cessation improves the risk of CVD.

Background: The PARALLEL-HF study assessed the efficacy and safety of sacubitril/valsartan vs. enalapril in Japanese patients with chronic heart failure with reduced ejection fraction (HFrEF). This open-label extension (OLE) assessed long-term safety with sacubitril/valsartan.Methods and Results: This study enrolled 150 patients who received sacubitril/valsartan 50 or 100 mg, b.i.d., in addition to optimal background heart failure (HF) therapy. A dose level of sacubitril/valsartan 200 mg, b.i.d., was targeted by Week 8. At OLE baseline, higher concentrations of B-type natriuretic peptide (BNP) and urine cGMP, and lower concentrations of N-terminal pro B-type natriuretic peptide (NT-proBNP), were observed in the sacubitril/valsartan core group (patients who received sacubitril/valsartan in both the core and extension study) than in the enalapril core group (patients who received enalapril in the core study and were then transitioned to sacubitril/valsartan). The mean exposure to study drug was 98.9%. There was no trend of worsening of HF at Month 12. No obvious changes in cardiac biomarkers were observed, whereas BNP and urine cGMP increased and NT-proBNP decreased in the enalapril core group, which was evident at Weeks 2–4 and sustained to Month 12.Conclusions: Long-term sacubitril/valsartan at doses up to 200 mg, b.i.d., has a positive risk-benefit profile; it was safe and well tolerated in Japanese patients with chronic HFrEF.

Background:In the Prospective Comparison of angiotensin receptor neprilysin inhibitor (ARNI) With ACEi to Determine Impact on Global Mortality and Morbidity in Heart Failure (PARADIGM-HF) study, treatment with sacubitril/valsartan reduced the primary outcome of cardiovascular (CV) death and heart failure (HF) hospitalization compared with enalapril in patients with chronic HF and reduced ejection fraction (HFrEF). A prospective randomized trial was conducted to assess the efficacy and safety of sacubitril/valsartan in Japanese HFrEF patients.Methods and Results:In the Prospective comparison of ARNI with ACEi to determine the noveL beneficiaL trEatment vaLue in Japanese Heart Failure patients (PARALLEL-HF) study, 225 Japanese HFrEF patients (New York Heart Association [NYHA] class II–IV, left ventricular ejection fraction [LVEF] ≤35%) were randomized (1 : 1) to receive sacubitril/valsartan 200 mg bid or enalapril 10 mg bid. Over a median follow up of 33.9 months, no significant between-group difference was observed for the primary composite outcome of CV death and HF hospitalization (HR 1.09; 95% CI 0.65–1.82; P=0.6260). Early and sustained reductions in N-terminal pro-brain natriuretic peptide (NT-proBNP) from baseline were observed with sacubitril/valsartan compared with enalapril (between-group difference: Week 2: 25.7%, P<0.01; Month 6: 18.9%, P=0.01, favoring sacubitril/valsartan). There was no significant difference in the changes in NYHA class and Kansas City Cardiomyopathy Questionnaire (KCCQ) clinical summary score at Week 8 and Month 6. Sacubitril/valsartan was well tolerated with fewer study drug discontinuations due to adverse events, although the sacubitril/valsartan group had a higher proportion of patients with hypotension.Conclusions:In Japanese patients with HFrEF, there was no difference in reduction in the risk of CV death or HF hospitalization between sacubitril/valsartan and enalapril, and sacubitril/valsartan was safe and well tolerated.

Recent studies have revealed that decline in cellular nicotinamide adenine dinucleotide (NAD+) levels causes aging-related disorders and therapeutic approaches increasing cellular NAD+ prevent these disorders in animal models. The administration of nicotinamide mononucleotide (NMN) has been shown to mitigate aging-related dysfunctions. However, the safety of NMN in humans have remained unclear. We, therefore, conducted a clinical trial to investigate the safety of single NMN administration in 10 healthy men. A single-arm non-randomized intervention was conducted by single oral administration of 100, 250, and 500 mg NMN. Clinical findings and parameters, and the pharmacokinetics of NMN metabolites were investigated for 5 h after each intervention. Ophthalmic examination and sleep quality assessment were also conducted before and after the intervention. The single oral administrations of NMN did not cause any significant clinical symptoms or changes in heart rate, blood pressure, oxygen saturation, and body temperature. Laboratory analysis results did not show significant changes, except for increases in serum bilirubin levels and decreases in serum creatinine, chloride, and blood glucose levels within the normal ranges, independent of the dose of NMN. Results of ophthalmic examination and sleep quality score showed no differences before and after the intervention. Plasma concentrations of N-methyl-2-pyridone-5-carboxamide and N-methyl-4-pyridone-5-carboxamide were significantly increased dose-dependently by NMN administration. The single oral administration of NMN was safe and effectively metabolized in healthy men without causing any significant deleterious effects. Thus, the oral administration of NMN was found to be feasible, implicating a potential therapeutic strategy to mitigate aging-related disorders in humans.

Background Associations between hyperuricemia, cardiovascular diseases and diabetes have been reported, but few of the studies have been conducted in the Korean population. The present study examined a Korean adult population with respect to the relationships between serum uric acid concentrations and hypertension, insulin resistance, and the risk factors of metabolic syndrome. Methods and Results A total of 53,477 subjects were divided into 4 groups according to serum uric acid quartiles. The incidence of hypertension in all subjects was higher in the first quartile than in the third plus fourth quartile (odds ratio (OR) 1.192, p<0.001). Homeostasis model assessment index was found to be associated with serum uric acid concentration in all subjects (OR 1.193, p<0.001), and the serum uric acid concentration was positively correlated with the risk factors of metabolic syndrome. In addition, the number of metabolic syndrome variables increased as serum uric acid concentration increased. Conclusions Serum uric acid concentration was found to be independently correlated with hypertension, insulin resistance and the risk factors of metabolic syndrome. In addition, even those with a serum uric acid concentration in the normal range showed an increased risk of metabolic syndrome as serum uric acid concentration increased.

Background: Impact of immeasurable time bias (IMTB) is yet to be examined in self-controlled designs.Methods: We conducted case-crossover, case-time-control, and case-case-time-control analyses using Korea’s healthcare database. Two empirical examples among elderly patients were used: 1) benzodiazepines-hip fracture; 2) benzodiazepines-mortality. For cases, the date of hip fracture diagnosis or death was defined as the index date, and the inherited date of their matched cases for controls or future cases. Exposure was assessed in the 1–30 day (hazard) and 61–90 day (control) windows preceding the index date. A non-missing exposure setting included in- and outpatient prescriptions and the pseudo-outpatient setting included only the outpatients. Conditional logistic regression was done to estimate odds ratios (ORs) with 95% confidence intervals (CIs), where the relative difference in OR among the two settings was calculated to quantify the IMTB.Results: The IMTB had negligible impacts in the hip fracture example in the case-crossover (non-missing exposure setting OR 1.27; 95% CI, 1.12–1.44; pseudo-outpatient setting OR 1.21; 95% CI, 1.06–1.39; magnitude 0.05), case-time-control (OR 1.18; 95% CI, 0.98–1.44; OR 1.13; 95% CI, 0.92–1.38; 0.04, respectively), and case-case-time-control analyses (OR 0.99; 95% CI, 0.80–1.23; OR 0.94; 95% CI, 0.75–1.18; 0.05, respectively). In the mortality example, IMTB had significant impacts in the case-crossover (non-missing exposure setting OR 1.44; 95% CI, 1.36–1.52; pseudo-outpatient setting OR 0.72; 95% CI, 0.67–0.78; magnitude 1.00), case-time-control (OR 1.38; 95% CI, 1.26–1.51; OR 0.68; 95% CI, 0.61–0.76; 1.03, respectively), and case-case-time-control analyses (OR 1.27; 95% CI, 1.15–1.40; OR 0.62; 95% CI, 0.55–0.69; 1.05, respectively).Conclusion: Although IMTB had negligible impacts on the drug’s effect on acute events, as these are unlikely to be accompanied with hospitalizations, it negatively biased the drug’s effect on mortality, an outcome with prodromal phases, in the three self-controlled designs.

Background: Lower systolic blood pressure (SBP) is known to be associated with poor prognosis in heart failure (HF). We evaluated the efficacy and safety of sacubitril/valsartan according to baseline SBP tertiles in Japanese patients from the PARALLEL-HF study.Methods and Results: In all, 223 patients were stratified into tertiles according to baseline SBP (≤114 mmHg: n=75; >114 and ≤130 mmHg: n=76; and >130 mmHg: n=72). Patients with lower SBP (≤114 mmHg) had the highest median N-terminal pro B-type natriuretic peptide (NT-proBNP) concentrations at baseline (P=0.0184). No significant difference was observed between sacubitril/valsartan and enalapril for the composite outcome of cardiovascular death and HF hospitalization across SBP tertiles (P-interaction=0.2682). Although the P-interaction value was not significant (0.2106), a greater reduction in NT-proBNP with sacubitril/valsartan compared with enalapril was observed in patients with SBP >130 mmHg (P=0.0076). The incidence of hypotension-related events and reduction or discontinuation of treatment due to hypotension-related events was higher in the lower SBP subgroup, and these events were more frequent in the sacubitril/valsartan than enalapril group.Conclusions: The efficacy of sacubitril/valsartan compared with enalapril was consistent across baseline SBP tertiles in Japanese patients from the PARALLEL-HF study. Hypotension-related events were more common in patients treated with sacubitril/valsartan with lower SBP.

Cognitive decline is a well-known chronic side effect of multidisciplinary treatment of pineal region tumors, whereas epilepsy is an under-reported chronic consequence caused by multiple potential factors including radiotherapy, surgery, or chemotherapy. Some long-term survivors have suffered drug-resistant epilepsy after treatment, which impaired the quality of life. We report five consecutive patients with drug-resistant epilepsy after combined treatment of pineal region tumor (5 men, aged 21–42 years) among 1201 epilepsy patients who underwent comprehensive evaluation in our tertiary epilepsy center from 2011 to 2018. The comprehensive epilepsy evaluation included medical interview, long-term video electroencephalography (EEG) monitoring (VEM), and magnetic resonance (MR) imaging. The patients started to have seizures at 2–22 years after initial treatment for the tumor. Four of the five patients had focal impaired awareness seizures, whereas one patient had only visual aura. All patients had EEG seizures during VEM, which confirmed the diagnosis of focal epilepsy, but three patients had no interictal epileptiform discharges (IEDs). Two patients had diagnoses of focal epilepsy arising from the left occipital region based on ictal EEG findings. Both patients had MR imaging lesion in the left occipital lobe, radiation-induced cavernoma, or surgical injury. The remaining three patients showed poor localization of epileptogenic foci based on VEM and MR imaging. Drug-resistant epilepsy after multidisciplinary treatment of pineal region tumor is characterized by focal impaired awareness seizures with poorly localized EEG onset or rare interictal spikes.

Objective: Basilar artery occlusion (BAO) secondary to traumatic vertebral artery (VA) dissection caused by vertebral fracture is a rare cause of acute ischemic stroke, and optimal management, such as antithrombotic agents, surgical fixation, and parent artery occlusion (PAO), has been controversial. We report a case in which mechanical thrombectomy and PAO were performed for a BAO due to right VA dissection caused by a transverse foramen fracture of the axis vertebra.Case Presentation: A patient in her 80s suffered from a backward fall, and a neck CT revealed a fracture and dislocation of the right lateral mass of the axis and a compressed transverse foramen. The patient was instructed to admit and to remain in bed rest; however, she suddenly lost consciousness the following day. The CTA revealed right VA occlusion and BAO; therefore, the patient underwent mechanical thrombectomy and the BAO was successfully reperfused but the VA stenotic dissection remained. PAO of the right VA was performed on the fifth day after the accident to prevent BAO recurrence.Conclusion: Mechanical thrombectomy is an effective treatment for BAO caused by VA dissection, and PAO may contribute to the prevention of stroke recurrence.

Management of nausea is an important dimension of palliative care. The first choice for treating nausea is antiemetics, but their efficacy is inadequate. Acupressure intervention for nausea in cancer patients has been studied as a non-pharmacological therapy, and appears to have had some effect. However, such a therapy has not been well reviewed in patients with terminal cancer. The purpose of this study was to clarify the feasibility of acupressure intervention and examine its safety and preliminary efficacy. We recruited cancer patients that fulfilled the eligibility criteria and were admitted to the palliative care unit, from August 2018 to February 2019, in Tohoku University Hospital, Japan. We conducted a longitudinal assessment of acupressure intervention in a single arm. We identified the patient’s research accomplishments and evaluated possible fainting due to the vagal reflex and symptom severity. Descriptive statistics were used to calculate the completion rate for the feasibility and Wilcoxon signed-rank tests to compare the average of continuous variables for the safety and efficacy. Twelve patients participated in this study and completed the procedure. Their average age was 70 years (SD = 9.3), and the most common primary cancer sites were the rectum and pancreas. The blood pressure and pulse rate did not drop sharply. Four patients exhibited decreased nausea but there was no statistically significant difference (P = 0.5). We suggested that acupressure has high feasibility and safety, as an intervention for patients with terminal cancer. However, no significant differences were observed regarding its effect on nausea.

The Great East Japan Earthquake, which occurred on March 11, 2011, and its subsequent Fukushima Daiichi Nuclear Power Plant accident, prompted implementation of the Thyroid Ultrasound Examination (TUE) program as a part of the Fukushima Health Management Survey. The purpose of this program is to support residents of Fukushima Prefecture, and to analyze the health effects of the released radionuclides. Regardless of relatively high participation rates and a well-planned diagnostic flow, it is conceivable that not all thyroid cancer cases can be detected by the TUE program. The aims of the present study were to identify and characterize these “outside” cases, targeting patients at Fukushima Medical University (FMU) Hospital. As of June 30, 2017, we have successfully identified 11 outside cases. These corresponded to 5.7% of the 194 subjects who were identified as having thyroid cancer or suspected thyroid cancer in the TUE program. Although the outside subjects of other institutes were not investigated, the present study may have identified the majority of outside subjects in Japan, considering that FMU Hospital treats a large number of thyroid cancer subjects. Furthermore, the characteristics of the 11 subjects were not different from those of the subjects identified in the TUE program. These findings confirm that the TUE program was able to identify subjects of thyroid cancer adequately and sufficiently.

Chemosynthetic microbial communities develop and form dense cell aggregates in slightly alkaline sulfidic hot springs in the temperature range of 70–86°C at Nakabusa, Japan. Nitrogenase activity has recently been detected in the microbial communities collected. To identify possible members capable of nitrogen fixation, we examined the diversities of 16S rRNA and nitrogenase reductase (NifH) gene sequences in four types of chemosynthetic communities with visually different colors and thicknesses. The results of a 16S rRNA gene analysis indicated that all four microbial communities had similar bacterial constituents; the phylum Aquificae was the dominant member, followed in abundance by Thermodesulfobacteria, Firmicutes, and Thermotogae. Most of the NifH sequences were related to sequences reported in hydrothermal vents and terrestrial hot springs. The results of a phylogenetic analysis of NifH sequences revealed diversity in this gene among the communities collected, distributed within 7 phylogenetic groups. NifH sequences affiliated with Aquificae (Hydrogenobacter/Thermocrinis) and Firmicutes (Caldicellulosiruptor) were abundant. At least two different energy metabolic pathways appeared to be related to nitrogen fixation in the communities analyzed; aerobic sulfur/hydrogen-oxidizing bacteria in Aquificae and fermentative bacteria in Firmicutes. The metabolic characteristics of these two dominant phyla differed from those previously inferred from nitrogenase activity assays on chemosynthetic communities, which were associated with hydrogen-dependent autotrophic sulfate reduction. These assays may correspond to the observed NifH sequences that are distantly related to the known species of Thermodesulfovibrio sp. (Nitrospirae) detected in the present study. The activities of nitrogen-fixing organisms in communities may depend on redox states as well as the availability of electron donors, acceptors, and carbon sources.
