Background: Evidence linking working hours and the risk of type 2 diabetes mellitus (T2DM) is limited and inconsistent in Asian populations. No study has addressed the combined association of long working hours and sleep deprivation on T2DM risk. We investigated the association of baseline overtime work with T2DM risk and assessed whether sleep duration modified the effect among Japanese.Methods: Participants were Japanese employees (28,489 men and 4,561 women) aged 30–64 years who reported overtime hours and had no history of diabetes at baseline (mostly in 2008). They were followed up until March 2014. New-onset T2DM was identified using subsequent checkup data, including measurement of fasting/random plasma glucose, glycated hemoglobin, and self-report of medical treatment. Hazard ratios (HRs) of T2DM were estimated using Cox regression analysis. The combined association of sleep duration and working hours was examined in a subgroup of workers (n = 27,590).Results: During a mean follow-up period of 4.5 years, 1,975 adults developed T2DM. Overtime work was not materially associated with T2DM risk. In subgroup analysis, however, long working hours combined with insufficient sleep were associated with a significantly higher risk of T2DM (HR 1.42; 95% CI, 1.11–1.83), whereas long working hours with sufficient sleep were not (HR 0.99; 95% CI, 0.88–1.11) compared with the reference (<45 hours of overtime with sufficient sleep).Conclusions: Sleep duration modified the association of overtime work with the risk of developing T2DM. Further investigations to elucidate the long-term effect of long working hours on glucose metabolism are warranted.

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.

Background: There is a strong demand for remote monitoring systems to gather health data. This study investigated the safety, usefulness, and patient satisfaction in outpatient care using telehealth with real-time electrocardiogram (ECG) monitoring after catheter ablation.Methods and Results: In all, 38 patients who underwent catheter ablation were followed up using telehealth. At the 3- and 6-month follow-up, a self-fitted Duranta ECG monitoring device was sent to the patient’s home before the online consultation. Patients attached the devices themselves, and the doctors viewed the patients by video chat and performed real-time ECG monitoring. The frequency of hospital visits and the ECG monitoring duration were compared with conventional in-person follow-up data (n=102). The completion rate for telehealth follow-up was 32 of 38 patients (84%). The number of hospital visits during the 6 months was significantly lower with telehealth follow-up than with conventional follow-up (median [interquartile range] 1 [1–1] vs. 5 [3–5]; P<0.0001). However, the ECG monitoring duration was approximately 4-fold longer for the telehealth follow-up (median [interquartile range] 89 [64–117] vs. 24 [0.1–24] h; P<0.0001). No major adverse events were observed during the telehealth follow-up. Patient surveys showed high satisfaction with telehealth follow-up due to reduced hospital visits.Conclusions: A combination of telehealth follow-up with real-time ECG monitoring increased the ECG monitoring duration and patient satisfaction without any adverse events.

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.

Background: Carpal tunnel syndrome (CTS) is considered an early sign of cardiac amyloidosis (CA) because amyloid deposition is often confirmed in the tenosynovium removed during carpal tunnel release (CTR); however, the prevalence of concomitant CA is unclear.Methods and Results: We prospectively examined 700 patients who underwent CTR and evaluated amyloid deposition after tenosynovium removal. Amyloid deposition was observed in 261 (37%) patients, who were significantly older and predominantly male (P<0.05). Of them, 120 agreed to cardiac screening. We performed 99 mTc-labeled pyrophosphate (99 mTc-PYP) scintigraphy in 12 patients who met either of the following criteria: (1) interventricular septal diameter (IVSd) ≥14 mm or (2) 12 mm ≤ IVSd < 14 mm with above-normal limits in high-sensitivity cardiac troponin T (hs-cTnT). Six patients (50%) had positive findings on 99 mTc-PYP scintigraphy and were diagnosed with wild-type transthyretin CA. Concomitant CA was observed in 6/120 (5%) CTR patients with amyloid deposition and 50% (6/12) in patients with left ventricular hypertrophy (≥12 mm) with increased hs-cTnT levels.Conclusions: Amyloid deposition was frequently observed in the removed tenosynovium of elderly men with CTS. Cardiac screening may be useful for early diagnosis of CA in patients undergoing CTR with amyloid deposition.

別役実の短編小説「愛のサーカス」は、かつて中学校1 年生向け国語教科書に掲載されていた、ユニークな内容の教材である(『新しい国語1』、『新編新しい国語1』東京書籍、平成二年度~十二年度)。十年以上のブランクを経て、平成二十六年度より高等学校向けの国語教科書に掲載されることとなった(『探求現代文B』桐原書店、高校3 年生配当)。なぜこのように配当学年が大きく変わったのか。それは「細部の発見」によって、小説の解釈が大きく変化したためだというのが本稿の主張である。これまで見すごされてきた「細部」(根拠)に着目することで、中心人物の一人である少年の人物像の理解が深まると同時に、それと連動する形で変化したラストシーンの論理的な説明が複雑であるため、配当学年が大きく変化したのではないかと主張した。

Background:The purpose of this study was to clarify the implementation rate of multidisciplinary heart failure (HF) care and cardiac rehabilitation (CR) in Japan, as well as the relationship between implementation rates and characteristics of the facility.Methods and Results:Survey participants were cardiologists who are members of the Japan Heart Failure Society and belonged to 1 of 845 medical institutions that are members of the Japan Heart Failure Society, as of April 2016. A total of 288 institutions (34.1%) returned the questionnaire. The percentages of hospitals implementing multidisciplinary HF care were 78.5% for inpatients and 32.6% for outpatients with HF. Inpatient and outpatient CR for HF had implementation rates of 80.4% and 56.5%, respectively. In addition, very few HF patients (7.3%, 3,741/51,323 patients) received outpatient CR. Both the presence of nurses certified in chronic HF care and registered CR instructors on staff were consistently associated with implementation of multidisciplinary HF care, and Japanese Circulation Society training hospitals, lower number of hospital beds, and presence of registered CR instructors on staff were consistently associated with implementation of CR.Conclusions:This first nationwide survey demonstrated that the implementation rates of multidisciplinary care and CR for HF, especially for outpatients, are low in Japan. Skilled healthcare professionals are expected to play important roles in the widespread implementation of this type of HF care in Japan.

Safety assessments of cosmetics are carried out by identifying possible harmful effects of substances in cosmetic products and assessing the exposure to products containing these substances. The present study provided data on the amounts of cosmetic products consumed in Japan to enhance and complement the existing data from Europe and the United States, i.e., the West. The outcomes of this study increase the accuracy of exposure assessments and enable more sophisticated risk assessment as a part of the safety assessment of cosmetic products. Actual amounts of products applied were calculated by determining the difference in the weight of products before and after use by approximately 300 subjects. The results of the study of skincare products revealed that in comparison with the West, large amounts of lotions and emulsions were applied, whereas lower amounts of cream and essence were applied in Japan. In the study of sunscreen products, actual measured values during outdoor leisure use were obtained, and these were lower than the values from the West. The study of the use of facial mask packs yielded data on typical Japanese sheet-type impregnated masks and revealed that high amounts were applied. Furthermore, data were obtained on cleansing foams, makeup removers and makeup products. The data from the present study enhance and complement existing information and will facilitate more sophisticated risk assessments. The present results should be extremely useful in safety assessments of newly developed cosmetic products and to regulatory authorities in Japan and around the world.

Bradyrhizobium sp. S23321 is an oligotrophic bacterium isolated from paddy field soil. Although S23321 is phylogenetically close to Bradyrhizobium japonicum USDA110, a legume symbiont, it is unable to induce root nodules in siratro, a legume often used for testing Nod factor-dependent nodulation. The genome of S23321 is a single circular chromosome, 7,231,841 bp in length, with an average GC content of 64.3%. The genome contains 6,898 potential protein-encoding genes, one set of rRNA genes, and 45 tRNA genes. Comparison of the genome structure between S23321 and USDA110 showed strong colinearity; however, the symbiosis islands present in USDA110 were absent in S23321, whose genome lacked a chaperonin gene cluster (groELS3) for symbiosis regulation found in USDA110. A comparison of sequences around the tRNA-Val gene strongly suggested that S23321 contains an ancestral-type genome that precedes the acquisition of a symbiosis island by horizontal gene transfer. Although S23321 contains a nif (nitrogen fixation) gene cluster, the organization, homology, and phylogeny of the genes in this cluster were more similar to those of photosynthetic bradyrhizobia ORS278 and BTAi1 than to those on the symbiosis island of USDA110. In addition, we found genes encoding a complete photosynthetic system, many ABC transporters for amino acids and oligopeptides, two types (polar and lateral) of flagella, multiple respiratory chains, and a system for lignin monomer catabolism in the S23321 genome. These features suggest that S23321 is able to adapt to a wide range of environments, probably including low-nutrient conditions, with multiple survival strategies in soil and rhizosphere.

ObjectiveThis study aimed to estimate incidence rates of femoral shaft fracture in patients who were treated with antiresorptive drugs.DesignCohort studyMethodsWe used data from the National Database of Health Insurance Claims of Japan from April 2009 and October 2016. All patients with new use of an antiresorptive drug, prescription-free period of ≥3 months, and no prior femoral fractures were included. Femoral shaft fractures were identified using a validated definition based on ICD-10 codes. Incidence rate ratios were estimated using Poisson regression with adjustment for sex, age, and the Charlson Comorbidity Index.ResultsWe identified 7,958,655 patients (women, 88.4%; age ≥75 years, 51.2%). Femoral shaft fractures were identified in 22,604 patients. Incidence rates per 100,000 person-years was 74.8 for women, 30.1 for men, 30.1 for patients aged ≤64 years, 47.7 for patients aged 65–74 years, and 99.0 for patients aged ≥75 years. Adjusted incidence rate ratios in patients taking versus not taking each type of antiresorptive drug were 1.00 (95% confidence interval (CI), 0.98–1.03) for bisphosphonates, 0.46 (95% CI, 0.44–0.48) for selective estrogen receptor modulators, 0.24 (95% CI, 0.18–0.32) for estrogens, 0.75 (95% CI, 0.71–0.79) for calcitonins, and 0.93 (95% CI, 0.84–1.03) for denosumab. The adjusted incidence rate ratio for alendronate was 1.18 (95% CI, 1.14–1.22).ConclusionsThe incidence rates of femoral shaft fracture varied across patients treated with different antiresorptive drugs. Further research on a specific antiresorptive drug can increase understanding of the risk of femoral shaft fracture
