Abstract
A traumatic iliacus hematoma is rare and usually occurs in patients after a fall involving a lower back injury. Although the hematoma may compress the femoral nerve causing femoral nerve palsy, the gold standard treatment for this condition has not been established. Here we report transcatheter arterial embolisation as a useful treatment strategy for a traumatic iliacus hematoma.

Abstract
Progressive supranuclear palsy - Richardson syndrome (PSP-RS) was first described in 1964 by Steele et al. Tau pathology has not been reported in the hypoglossal nuclei of PSP-RS patients, whereas Steele et al. described gliosis with no remarkable neuronal losses in the hypoglossal nucleus. This study aimed to investigate the distribution and degree of tau pathology-associated neurodegeneration, with an emphasis on the hypoglossal nucleus, in patients with PSP-RS. Six clinicopathologically proven PSP-RS cases were included in this study. All patients were clinicopathologically and immunohistochemically re-evaluated. This study confirmed the following neuropathological characteristics of PSP-RS: (1) neurodegeneration usually affects the striatonigral system and cerebellar dentate nucleus; (2) the cerebellar afferent system in PSP-RS is affected by absent-to-mild neurodegeneration; and (3) the extent of tau distribution throughout the central nervous system is greater than the extent of neurodegeneration. Furthermore, we found that subthalamic neurodegeneration was more prominent in the ventromedial region than in the dorsolateral region. Nevertheless, the tau pathology showed no remarkable differences between these two sites. Interestingly, the tau pathology was frequently observed in the hypoglossal nuclei of PSP-RS patients. Gradient neurodegeneration of the subthalamus and tau pathology in the hypoglossal nucleus could be regarded as essential pathological features of PSP-RS.

Abstract
Searching for space-time variations of the constants of Nature is a promising way to search for new physics beyond general relativity and the standard model motivated by unification theories and models of dark matter and dark energy. We propose a new way to search for a variation of the fine-structure constant using measurements of late-type evolved giant stars from the S star cluster orbiting the supermassive black hole in our Galactic Center. A measurement of the difference between distinct absorption lines (with different sensitivity to the fine structure constant) from a star leads to a direct estimate of a variation of the fine structure constant between the star's location and Earth. Using spectroscopic measurements of five stars, we obtain a constraint on the relative variation of the fine structure constant below 10^{-5}. This is the first time a varying constant of nature is searched for around a black hole and in a high gravitational potential. This analysis shows new ways the monitoring of stars in the Galactic Center can be used to probe fundamental physics.

Abstract
OBJECTIVES To clarify the effectiveness of ward-assigned dental hygienists (DHs) on rehabilitation outcomes in rehabilitation wards. DESIGN Retrospective cohort study. SETTING The registry data from the Japanese Rehabilitation Nutrition Database. PARTICIPANTS 656 patients with hip fracture or stroke admitted to convalescent rehabilitation wards. MEASUREMENTS The main outcome measures were the Functional Independence Measure (FIM), the Food Intake Level Scale (FILS), and the home discharge rate. Patients were divided into two groups based on the ward setting: with an assigned DH (DH group) and without an assigned DH (NDH group). Clinical characteristics and outcomes were compered between the groups. Between-facility differences were adjusted by generalized estimating equation. We performed post-hoc power analysis to confirm that there were enough samples included in this study to detect a significant difference. RESULTS Of 656 patients (mean age, 77 years; 57.1% female; 65.5% stroke) from 10 facilities, 454 patients (69.2%) from 4 facilities were in the DH group. FIM score at discharge (107 vs 90, P<0.001), percentage improvement in FILS score from admission to discharge (44.5% vs 22.8%, P<0.001) and home discharge rate (72.5% vs 61.4%, P<0.001) were significantly higher in the DH group than in the NDH group. After multivariate analysis, the FIM score at discharge (P=0.007), FILS score at discharge (P=0.024), and home discharge rate (P=0.007) were significantly higher in the DH group than in the NDH group. CONCLUSIONS ADL and swallowing function were significantly improved at discharge and the home discharge rate was higher among patients in rehabilitation wards with DHs. Having a ward-assigned DH may lead to better rehabilitation outcomes in rehabilitation wards.

Abstract
High emissions of air pollutants from Northeast Asia are strongly influenced by air quality as well as by ecosystems. This study investigated the spatiotemporal variations in the sulfur isotopic ratio (δ34S) in atmospheric deposition at eleven monitoring stations in Japan from 2011 to 2016 and estimated the amount of transboundary transported anthropogenic sulfate (TRB) deposition using mass balance calculations. The δ34S of sulfate in precipitation ranged from -0.42 to +22.7‰. Sea salt (SS), TRB, and domestic anthropogenic sources (DOM) were the dominant sources of sulfate deposition in Japan. TRB sulfate deposition was largest on the Sea of Japan side, with an annual average value of 1.5 ± 0.3-6.9 ± 0.5 mg m-2 d-1 (36-44%), followed by Mt. Happo (4.5 ± 0.1 mg m-2 d-1; 88%), the Pacific Ocean side (1.5 ± 0.8, 4.3 ± 0.9 mg m-2 d-1; 24-50%), and the remote islands in the North Pacific Ocean (1.1 ± 0.2, 2.0 ± 0.8 mg m-2 d-1; 19-32%). TRB sulfate deposition on the Sea of Japan side was 2-12 times higher in winter and 1-2 times higher in summer than that of DOM. In contrast, TRB sulfate deposition on the Pacific Ocean side was 1.5-3 times higher in summer than in winter due to high precipitation levels. In Tokyo, the annual contribution from DOM sulfate deposition is approximately three times higher than that from TRB. Annual TRB sulfate deposition is lowest at Ogasawara at 1.1 ± 0.2 mg m-2 d-1, and the annual oceanic DMS contribution to sulfate deposition is high, accounting for 1.3 mg m-2 d-1 (20 ± 6%). The contribution of Asian dust was estimated to be 1-5.2 mg m-2 d-1(3-6%), which occurred in a single Asian dust event on the Sea of Japan side.

Abstract
Abstract
Background
Combined near-infrared spectroscopy (NIRS) and intravascular ultrasonography (NIRS-IVSU) is an imaging modality for precise detection of lipid core burden. Distal embolization has been reported to be a mechanism of microcirculatory dysfunction (MD) caused by percutaneous coronary intervention (PCI). High lipid core burden index at the 4-mm maximal segment (max-LCBI(4)) has been associated with the cardiovascular event. A max-LCBI(4) of >500 was related to perioperative myocardial infarction even in patients with stable angina pectoris. Unlike 12-lead electrocardiography, intracoronary electrocardiography can detect slight ischemia during PCI, maybe indicating distal embolization. However, whether PCI for culprit plaques with a low max-LCBI(4) can cause MD is unclear. Thus, this study aimed to investigate whether plaques with low max-LCBI(4) influence MD, using intracoronary electrocardiography.
Methods
Forty consecutive patients who underwent PCI for stable angina pectoris due to stenosis of the proximal segment of the left anterior descending artery were enrolled. NIRS-IVUS was performed in all the patients before predilatation to evaluate for the culprit lesion. Total LCBI and max-LCBI(4) within the culprit lesion were measured. On gray-scale IVUS, vessel area, lumen area, plaque volume, and percent (%) plaque volume were measured. Intracoronary electrography was performed at stent implantation to measure the time from the initiation of S-T segment elevation from the isoelectric baseline to the return of S-T segment to the isoelectric baseline after the deflation of the stent balloon, which was defined as the severity of the MD. The patients were divided into 2 groups according to median max-LCBI(4) (high [n=20] and low LCBI groups [n=20]).
Results
The mean age was 72±6 years. Of the patients, 80% were male. The mean overall max-LCBI(4) was 140±100. Max-LCBI(4) was significantly higher in the high-LCBI(4) group than in the low-LCBI(4) group. No significant differences in age, body mass index, American College of Cardiology and American Heart Association classification, and low-density lipoprotein level were found between the groups, as well as in the gray-scale IVUS parameters such as %plaque volume. The mean time from the initiation of the initiation of S-T segment elevation from the isoelectric baseline to the return of S-T segment to the isoelectric baseline was significantly longer in the high LCBI group than in the low LCBI group (33 vs 12 sec, P=0.01) despite no change in the S-T segment on 12-lead electrography. The S-T segment elevation occurred only during stent balloon inflation and returned to the isoelectric baseline immediately after stent balloon deflation at a max-LCBI(4) of 0. The no-reflow and slow flow phenomena were not observed.
Conclusion
Even low max-LCBI(4) on NIRS-IVUS was associated with MD during PCI in patients with stable angina pectoris.

Abstract
Background Mental disorders and suicide resulting from overwork or work-related stress have become major occupational health issues worldwide, particularly in Asian countries. However, no studies have reported incidence rates of mental disorders and suicide by sex, age group and industry, using a national database containing all cases involving compensation in Asian countries. Aims The present study examined incidence rates of occupational mental disorders and suicide by sex, age group and industry using a database containing all cases involving compensation for mental disorders and suicide in Japan over a 5-year period. Methods Cases involving compensation for mental disorders and suicide in Japan between January 2010 and March 2015 were analysed. Incidence rates over the 5-year study period were calculated by sex, age group and industry. Results In total, 1990 cases involving compensation for mental disorders and suicide (619 women and 1371 men) between January 2010 and March 2015 were analysed. The incidence rate involving compensation was higher in employees aged between 30 and 39 years. In men, incidence rates were higher in 'accommodation/eating/drinking services', 'information/communication' and 'scientific research, professional and technical services'. In these industries, incidence rates were particularly high for those aged 29 years or younger. Conclusions Our findings highlight the importance of promoting mental health support for younger employees and increasing awareness of their working conditions. Differences in incidence rates by sex, age and industry should be taken into consideration in the development of a national policy and industry- and age-specific preventive measures for overwork-related mental disorders and suicide.

Abstract
Background Treatment of periprosthetic joint infection (PJI) is challenging, generally requiring complete implant removal. However, recently reported treatments involve partial retention of implants because of the severe local and systemic burden on the patients and difficulties in functional preservation. Long-term results should be evaluated because of the risk of residual biofilm on the retained implant and late infection recurrence. We evaluated 6 to 13-year clinical outcomes of two-stage treatment of chronic PJI retaining well-fixed cementless stems. Methods Among 36 surgeries for deep infection following hip arthroplasty performed from 2004 to 2011, six hips had a well-fixed and well-functioning cementless stem. These six hips were all chronic PJI and were treated without stem removal. The first-stage surgery involved acetabular cup removal and reconstruction by filling the acetabular defect with antibiotic-loaded acrylic cement, creating a socket-like hemispherical dent, and reducing the retained femoral head to this dent. After confirming infection eradication the second-stage acetabular reconstruction was performed. One patient died of an unrelated noninfective cause 1 year after the operation. Clinical outcomes of the remaining five patients were followed for 6 to 13 years. Results Between the two surgeries (range; 2–5 months), patients underwent active range-of-motion and ambulation exercises. No dislocation was found during the interval. No recurrence of infection was found and good functional outcomes and radiographic findings were observed during the average follow-up of 109 months in all five patients. Conclusions Two-stage treatment with retention of a well-fixed stem may minimize local and systemic burden of the patient and enhance functional preservation while obtaining long-term infection control. Although further study could establish the effectiveness and indications for this treatment option, currently used indications should be carefully evaluated considering factors including local and systemic conditions of the patient, implant fixation status, and type of bacteria.

Abstract
X-chromosome inactivation pattern (XCIP) analysis can be used to assess the clonality of cell populations of various origin by distinguishing the methylated X chromosome from the unmethylated X chromosome. In this study, the utility of XCIP analysis was improved by incorporating the examination of AC dinucleotide repeats in SLIT and NTRK-like family member 4 (SLITRK4) gene into the previously reported CAG repeat examination of androgen receptor (AR) gene in dogs. The rate of heterozygosity when both genes were analysed (125/150, 83.3%) was higher than AR gene examination alone (86/150, 57.3%). Blood samples from heterozygous dogs in either AC-1 or AC-2 of SLITRK4 gene were examined for the corrected inactivation allele ratio (CIAR), resulting in the determination of a reference range of CIAR <3.8 in non-neoplastic cell/tissue samples. Using this analytical method, 49% (21/43) of neoplastic tissue samples from dogs showed a CIAR >3.8, indicating the presence of a clonal population. Through the present study, the availability of canine XCIP analysis was improved by incorporating the examination of the SLITRK4 gene, providing a highly useful laboratory examination system for the detection of the clonality of various cell/tissue samples in dogs.
