Demonstrating Agreement between Radio and Fluorescence Measurements of the Depth of Maximum of Extensive Air Showers at the Pierre Auger Observatory. PHYSICAL REVIEW LETTERS 2024; 132:021001. [PMID: 38277596 DOI: 10.1103/physrevlett.132.021001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/30/2023] [Revised: 10/16/2023] [Accepted: 10/24/2023] [Indexed: 01/28/2024]
Abstract
We show, for the first time, radio measurements of the depth of shower maximum (X_{max}) of air showers induced by cosmic rays that are compared to measurements of the established fluorescence method at the same location. Using measurements at the Pierre Auger Observatory we show full compatibility between our radio and the previously published fluorescence dataset, and between a subset of air showers observed simultaneously with both radio and fluorescence techniques, a measurement setup unique to the Pierre Auger Observatory. Furthermore, we show radio X_{max} resolution as a function of energy and demonstrate the ability to make competitive high-resolution X_{max} measurements with even a sparse radio array. With this, we show that the radio technique is capable of cosmic-ray mass composition studies, both at Auger and at other experiments.

Abstract
Erythritol (ERT) and L-ascorbyl-2-phosphate (APS) are bacteriostatic, but their effects on staphylococcal skin infections remain unknown. We aimed to determine whether ERT combined with APS inhibits the growth of staphylococci that are commonly isolated from pyoderma skin lesions in dogs. We investigated the individual and combined effects of ERT and APS on the growth of Staphylococcus pseudintermedius, S. schleiferi, and S. aureus using turbidity assays in vitro. Skin lesions from 10 dogs with superficial pyoderma were topically treated with 5% ERT and 0.1% APS for 28 days, and swabbed skin samples were then analyzed using 16S rRNA amplicon sequencing and quantitative real-time PCR (qPCR). Results showed that ERT inhibited S. pseudintermedius growth regardless of harboring the mecA gene, and APS increased the inhibitory effects of ERT against S. pseudintermedius, S. schleiferi, and S. aureus in vitro. Moreover, combined ERT and APS decreased the prevalence of staphylococci on canine skin lesions at the genus level. The combination slightly increased the α-diversity but did not affect the β-diversity of the microbiota. The qPCR results revealed that the combination significantly decreased S. pseudintermedius and S. schleiferi in skin lesions. Topical administration of EPS combined with APS can prevent staphylococcal colonization on the surface of mammalian skin. The results of this study may provide an alternative to systemic antibiotics for treating superficial pyoderma on mammalian skin surfaces.

Abstract
Cosmic rays are energetic charged particles from extraterrestrial sources, with the highest-energy events thought to come from extragalactic sources. Their arrival is infrequent, so detection requires instruments with large collecting areas. In this work, we report the detection of an extremely energetic particle recorded by the surface detector array of the Telescope Array experiment. We calculate the particle's energy as [Formula: see text] (~40 joules). Its arrival direction points back to a void in the large-scale structure of the Universe. Possible explanations include a large deflection by the foreground magnetic field, an unidentified source in the local extragalactic neighborhood, or an incomplete knowledge of particle physics.

Thermoelectric signature of quantum critical phase in a doped spin-liquid candidate. Nat Commun 2023; 14:3679. [PMID: 37344458 DOI: 10.1038/s41467-023-39217-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2022] [Accepted: 05/31/2023] [Indexed: 06/23/2023] Open
Abstract
Quantum spin liquid is a nontrivial magnetic state of longstanding interest, in which spins are strongly correlated and entangled but do not order; further intriguing is its doped version, which possibly hosts strange metal and unconventional superconductivity. A promising candidate of the doped spin liquid is a triangular-lattice organic conductor, κ-(BEDT-TTF)4Hg2.89Br8, recently found to hold metallicity, spin-liquid-like magnetism, and BEC-like superconductivity. The nature of the metallic state with the spin-liquid behaviour is awaiting to be further clarified. Here, we report the thermoelectric signature that mobile holes in the spin liquid background are in a quantum critical state and it pertains to the BEC-like superconductivity. The Seebeck coefficient divided by temperature, S/T, is enhanced on cooling with logarithmic divergence indicative of quantum criticality. Furthermore, the logarithmic enhancement is correlated with the superconducting transition temperature under pressure variation, and the temperature and magnetic field profile of S/T upon the superconducting transition change with pressure in a consistent way with the previously suggested BEC-BCS crossover. The present results reveal that the quantum criticality in a doped spin liquid emerges in a phase, not at a point, and is involved in the unconventional BEC-like nature.

Abstract
Probiotics and prebiotics are viable bacteria with beneficial effects on the host and components that selectively act on the beneficial commensal bacteria, respectively. The combined use of probiotics and prebiotics is termed synbiotics. Probiotic intake improves dysbiosis in the intestinal microbiota and can positively affect canine atopic dermatitis (CAD). However, clinical studies on improvements in CAD using synbiotics remain limited. In this study, 15 dogs with CAD who received prednisolone, a synthetic glucocorticoid (GC) used in the treatment of CAD, for more than 90 days were continuously treated with Lactobacillus paracasei M-1 from fermented food as a probiotic, and trisaccharide kestose as a prebiotic, for 90 days to determine their synbiotic effects on CAD. The CAD symptoms were evaluated using the canine atopic dermatitis lesion index (CADLI) and pruritus visual analog scores (PVAS) at 30, 60 and 90 days after synbiotic administration. The total prednisolone use for 90 days pre- and post-administration was also evaluated. Synbiotic administration significantly reduced the CADLI (pre: median, 28.0 [22.0-32.0]; 30 days: median, 20.0 [20.0-28.0]; 60 days: median, 20.0 [10.0-21.0]; 90 days: median, 12.0 [10.0-19.0]) and PVAS (pre: median, 6.0 [5.0-7.0]; 30 days: median, 3.0 [3.0-3.5]; 60 days: median, 3.0 [3.0-3.5]; 90 days: median, 2.0 [2.0-3.5]) scores, and reduced the total prednisone use over 90 days (pre: 112.0 [25-450] mg; post: 80.0 [18.-300.0] mg; p⟨0.001) in the 15 dogs. Thus, the synbiotic activity of L. paracasei M-1 and trisaccharide kestose can improve CAD.

Limits to Gauge Coupling in the Dark Sector Set by the Nonobservation of Instanton-Induced Decay of Super-Heavy Dark Matter in the Pierre Auger Observatory Data. PHYSICAL REVIEW LETTERS 2023; 130:061001.

Abstract
Instantons, which are nonperturbative solutions to Yang-Mills equations, provide a signal for the occurrence of quantum tunneling between distinct classes of vacua. They can give rise to decays of particles otherwise forbidden. Using data collected at the Pierre Auger Observatory, we search for signatures of such instanton-induced processes that would be suggestive of super-heavy particles decaying in the Galactic halo. These particles could have been produced during the post-inflationary epoch and match the relic abundance of dark matter inferred today. The nonobservation of the signatures searched for allows us to derive a bound on the reduced coupling constant of gauge interactions in the dark sector: α_{X}≲0.09, for 10^{9}≲M_{X}/GeV<10^{19}. Conversely, we obtain that, for instance, a reduced coupling constant α_{X}=0.09 excludes masses M_{X}≳3×10^{13} GeV. In the context of dark matter production from gravitational interactions alone, we illustrate how these bounds are complementary to those obtained on the Hubble rate at the end of inflation from the nonobservation of tensor modes in the cosmological microwave background.

Abstract
Abstract
Background
Patients with Fontan circulation are at an increased risk of developing thromboembolic events in the first 3–12 months after surgery [1,2]. Thromboembolic events can lead to significant mortality [3]. The current guidelines recommend the use of antithrombotic therapy, either aspirin or warfarin, as a primary thromboprophylaxis [4,5]. On the other hand, the main adverse effect of thromboprophylaxis is bleeding, which may increase the risk of death. However, there are limited data to assess the outcomes of the thromboembolic and bleeding complications of thromboprophylaxis. Therefore, this retrospective cohort study aimed to evaluate the safety and efficacy of thromboprophylaxis after Fontan surgery.
Methods
We identified 1903 patients who underwent Fontan surgery between June 2011 and September 2019 from the National Database of Health Insurance Claims and Specific Health Checkups of Japan. The patients were followed-up from 2 months to 1 year after Fontan surgery to assess the primary outcomes of thromboembolic and bleeding events. Moreover, we identified the factors associated with primary outcomes in this population using multivariate logistic regression analysis.
Results
A total of 1903 patients (56.1% male) underwent Fontan surgery at a median age of 3 years (1–22); 1815 patients (95.4%) had an extracardiac conduit. No thromboprophylaxis was prescribed to 65 patients (3.4%), whereas 228 patients (12.0%) received aspirin alone, 346 patients (18.2%) received warfarin alone, and 1264 patients (66.4%) received a combination therapy of aspirin and warfarin. In the first post-operative year, thromboembolic events occurred in 234 patients (12.3%) and bleeding events occurred in 202 patients (10.6%). Older age (odds ratio, 1.08; 95% confidence interval, 1.06–1.11) and aspirin use (odds ratio, 0.34; 95% confidence interval, 0.15–0.78) were independently associated with thromboembolic events. In particular, up to 5 months after surgery, the incidence rate of thromboembolism was significantly lower in patients who received aspirin alone (0.9%) than in those who received other thromboprophylaxis regimens (no thromboprophylaxis, 13.8%; warfarin, 7.5%; combination therapy, 7.4%; p<0.05). No significant difference in incidence of bleeding events was observed among the four thromboprophylaxis regimens. A history of postoperative hemorrhage (odds ratio, 1.49; 95% confidence interval, 1.01–2.21) and the use of a potassium channel blocker (odds ratio, 2.12; 95% confidence interval, 1.10–4.05) was associated with a higher risk of bleeding events.
Conclusions
In this study, patients who received aspirin alone showed a significantly lower incidence of thromboembolic events. Aspirin may be useful for preventing thromboembolism a year after Fontan surgery. After Fontan surgery, it is important to select a safe and effective thromboprophylaxis regimen and evaluate the risk factors for thromboembolic and bleeding events in a timely manner.

Abstract
Abstract
Introduction
There are many reports that patients with cardiovascular diseases including hypertension have already suffered from sleep disordered breathing (SDB). Furthermore, Continuous Positive Airway Pressure (CPAP) is effective for hypertension for improvement of sympathetic nervous activity reason. Previously, we reported that SDB is just as, if not more, important as common classical risk factors (hypertension, dyslipidemia, diabetes mellitus) for patients with cardiovascular diseases (Figure 1).
Purpose
Our aim in this study is to estimate the real-world data in the management of hypertension for patients with SDB after initiating CPAP treatment.
Methods
All patients were conducted full night polysomnography. One-hundred ninety-five patients showed obstructive SDB {apnea hypopnea index (AHI) >20/hour}, and CPAP treatment were initiated. According to Japanese society of hypertension guidelines for the managements of hypertension 2019 (JSH2019), we estimated the blood pressure and presence of blood pressure-lowering agents to assess effectiveness of CPAP treatment after six-month follow up.
Results
The study group consisted of 195 SDB patients (166 males, 29 females). The mean age was 59±7 years. Figure 2 showed the blood pressure and presence of blood pressure-lowering agents after initiating CPAP treatment. Group A which showed systolic blood pressure (SBP) <130 mmHg without intake of blood pressure-lowering agents was 20.9%. Group B which showed SBP <130 mmHg with intake of blood pressure-lowering agents was 9.6%. Group C showed SBP≥130 mmHg without intake of blood pressure-lowering agents was 30.5%. Group D showed SBP≥130 mmHg with intake of blood pressure-lowering agents was 39.0%.
Conclusion
We could estimate that there were high prevalence of hypertension for patients with SDB after initiating CPAP treatment. It is true that CPAP treatment have a beneficial effect on hypertension, but 70% patients (Group C and D) still remain inadequately treated. We need the strict blood pressure follow up for patient with SDB before and after initiating CPAP treatment.

Abstract
Artificial neural networks have revolutionized electronic computing. Similarly, molecular networks with neuromorphic architectures may enable molecular decision-making on a level comparable to gene regulatory networks1,2. Non-enzymatic networks could in principle support neuromorphic architectures, and seminal proofs-of-principle have been reported3,4. However, leakages (that is, the unwanted release of species), as well as issues with sensitivity, speed, preparation and the lack of strong nonlinear responses, make the composition of layers delicate, and molecular classifications equivalent to a multilayer neural network remain elusive (for example, the partitioning of a concentration space into regions that cannot be linearly separated). Here we introduce DNA-encoded enzymatic neurons with tuneable weights and biases, and which are assembled in multilayer architectures to classify nonlinearly separable regions. We first leverage the sharp decision margin of a neuron to compute various majority functions on 10 bits. We then compose neurons into a two-layer network and synthetize a parametric family of rectangular functions on a microRNA input. Finally, we connect neural and logical computations into a hybrid circuit that recursively partitions a concentration plane according to a decision tree in cell-sized droplets. This computational power and extreme miniaturization open avenues to query and manage molecular systems with complex contents, such as liquid biopsies or DNA databases.

Redox-labelled electrochemical aptasensors with nanosupported cancer cells. Biosens Bioelectron 2022; 216:114643.

Abstract
The transfer of redox-labelled bioelectrochemical sensors from proteins to cells is not straightforward because of the cell downward force issue on the surface of the sensors. In this paper, 20-nm-thick nanopillars are introduced to overcome this issue, in a well-controlled manner. We show on both molecular dynamics simulations and experiments that suspending cells a few nanometers above an electrode surface enables redox-labelled tethered DNA aptamer probes to move freely, while remaining at an interaction distance from a target membrane protein, i. e. epithelial cell adhesion molecule (EpCAM), which is typically overexpressed in cancer cells. By this nanopillar configuration, the interaction of aptamer with cancer cells is clearly observable, with 13 cells as the lower limit of detection. Nanoconfinement induced by the gap between the electrode surface and the cell membrane appears to improve the limit of detection and to lower the melting temperature of DNA aptamer hairpins, offering an additional degree of freedom to optimize molecular recognition mechanisms. This novel nanosupported electrochemical DNA cell sensor scheme including Brownian-fluctuating redox species opens new opportunities for the design of all-electrical sensors using redox-labelled probes.

The Role of the Ventromedial Prefrontal Cortex in Preferential Decisions for Own- and Other-Age Faces. Front Psychol 2022; 13:822234.

Abstract
Own-age bias is a well-known bias reflecting the effects of age, and its role has been demonstrated, particularly, in face recognition. However, it remains unclear whether an own-age bias exists in facial impression formation. In the present study, we used three datasets from two published and one unpublished functional magnetic resonance imaging (fMRI) study that employed the same pleasantness rating task with fMRI scanning and preferential choice task after the fMRI to investigate whether healthy young and older participants showed own-age effects in face preference. Specifically, we employed a drift-diffusion model to elaborate the existence of own-age bias in the processes of preferential choice. The behavioral results showed higher rating scores and higher drift rate for young faces than for older faces, regardless of the ages of participants. We identified a young-age effect, but not an own-age effect. Neuroimaging results from aggregation analysis of the three datasets suggest a possibility that the ventromedial prefrontal cortex (vmPFC) was associated with evidence accumulation of own-age faces; however, no clear evidence was provided. Importantly, we found no age-related decline in the responsiveness of the vmPFC to subjective pleasantness of faces, and both young and older participants showed a contribution of the vmPFC to the parametric representation of the subjective value of face and functional coupling between the vmPFC and ventral visual area, which reflects face preference. These results suggest that the preferential choice of face is less susceptible to the own-age bias across the lifespan of individuals.

Abstract
Erythritol helps both prevent and improve periodontal disease and is therefore widely used for dental care in humans. However, only a few studies have investigated the effects of erythritol on periodontal disease in animals. We hypothesized that erythritol could be used to prevent and improve periodontal disease also in canines and investigated the effects of erythritol on canine periodontal disease-related pathogenic bacteria using both in vitro and in vivo methods. The effect of erythritol on the proliferation of Porphyromonas gulae, which is reportedly associated with canine periodontal disease, was investigated in vitro. In addition, a 4-week intervention trial using an external gel preparation containing 5% erythritol was performed in canines with mild periodontal disease; changes in the microbiota around periodontal lesions were investigated using next-generation sequencing and bioinformatics analysis. The growth of P. gulae was significantly suppressed by erythritol in vitro. In the intervention study, the Shannon index, an indicator of the species distribution α-diversity, and the occupancy of several canine periodontal disease - related bacteria ( P. gulae, P. cangingivalis) were significantly decreased in periodontal lesions. Based on the results of in vitro and in vivo studies, we conclude that, as in humans, erythritol has bacteriostatic effects against periodontal disease - related bacteria in canines.

Abstract
Abstract
Background
Extra-cardiovascular incidental findings (IFs) on preoperative computed tomography (CT) are frequently observed in transcatheter aortic valve implantation (TAVI) candidates. However, the backgrounds of TAVI candidates and comorbidities differ based on the race and/or country, and data on IFs in a specific population are not always applicable to another.
Objective
To assess the prevalence, type, and clinical impact of IFs in Japanese TAVI candidates.
Methods
This was a retrospective, single-center, observational study. CT reports of 257 TAVI candidates were reviewed, and IFs were classified as (a) insignificant: findings that did not require further investigation, treatment, or follow-up; (b) intermediate: findings that needed to be followed up or were considered for further investigation but did not affect the planning of TAVI; and (c) significant: findings that required further investigation immediately or affected the planning of TAVI.
Results
At least one IF was found in 254 patients (98.8%). Insignificant, intermediate, and significant IFs were found in 253 (98.4%), 153 (59.5%), and 34 (13.2%) patients, respectively. Newly indicated significant IFs were found in 19 patients (7.4%). In 2 patients (0.8%), TAVI was canceled because of significant IFs. In patients who consequently underwent TAVI, the presence of significant IFs was not associated with the duration from CT performance to TAVI [28 (19–40) days vs. 27 (19–43) days, p=0.74] and all-cause mortality during the median follow-up period of 413 (223–805) days (p=0.44).
Conclusion
Almost all Japanese TAVI candidates had at least one IF, and the prevalence of significant IFs was not negligible. Although the presence of significant IFs was not associated with mid-term mortality, appropriate management of IFs was considered important.

Abstract
Abstract
Background
The changes in electrocardiographic left ventricular hypertrophy (ECG-LVH) after transcatheter aortic valve replacement (TAVR) are not fully elucidated.
Methods
This retrospective single-center study investigated 156 patients who underwent TAVR for severe aortic stenosis. Twelve-leads ECGs obtained before and at 2 days and 1, 6 and 12 months after TAVR were analyzed. Patients with an implanted pacemaker, with a bundle branch block before or after TAVR or whose electrocardiogram at any measuring point was not available were excluded. As an assessment of ECG-LVH, Sokolow-Lyon voltage, Cornell voltage, Cornell product and Peguero–Lo Presti voltage were evaluated.
Results
Finally, 64 patients were included. Sokolow-Lyon voltage, Cornell voltage, Cornell product and Peguero–Lo Presti voltage significantly decreased between 1 and 6 months after TAVR compared to baseline. The prevalence of ECG-LVH criteria for each parameter decreased as well. QRS duration significantly decreased at 6 months after TAVR and the number of patients with strain pattern decreased significantly at 1 month when compared to baseline. When the patients were divided into two groups, those with and without ECG-LVH at baseline, ECG-LVH parameter values decreased significantly, especially in patients with ECG-LVH at baseline.
Conclusion
Regression of ECG-LVH after TAVR was demonstrated as per various criteria of ECG-LVH. The voltages and prevalence of ECG-LVH decreased significantly between 1 and 6 months after TAVR.

Abstract
BACKGROUND Rice wine lees (RWL), a Japanese traditional fermented product, is a rich source of one-carbon metabolism-related nutrients, which may have beneficial effects on cognitive function. OBJECTIVES We aimed to examine the effect of the RWL on cognitive function in community-dwelling physically active older adults. DESIGN Double-blind, randomized, placebo-controlled study (clinical trial number: UMIN 000027158). SETTING Community-based intervention including assessments conducted at the University of Hyogo and a public liberal arts school in Himeji City, Japan. PARTICIPANTS A total of 35 community-dwelling older adults (68-80 years) who performed mild exercise before and during the trial were assigned to either the RWL (n=17) or the placebo group (n=18). INTERVENTION Daily consumption of 50 g RWL powder, which contained one-carbon metabolism-related nutrients, or the placebo powder (made from soy protein and dextrin) for 12 weeks. Both supplements included equivalent amounts of energy and protein. MEASUREMENTS Montreal Cognitive Assessment, computerized cognitive function test, and measurements of serum predictive biomarkers (transthyretin, apolipoprotein A1, and complement C3) were conducted at baseline and follow-up. RESULTS Visual selective attention and serum transthyretin significantly improved in the RWL group, whereas there was no significant change in the placebo group. No significant group difference was observed in the remaining cognitive performance tests. CONCLUSIONS RWL supplements seem to have a few effects on cognitive function in community-dwelling physically active older adults. However, the impact was limited; therefore, further studies with sufficient sample size are warranted to elucidate this issue.

Measurement of the Fluctuations in the Number of Muons in Extensive Air Showers with the Pierre Auger Observatory. PHYSICAL REVIEW LETTERS 2021; 126:152002.

Abstract
We present the first measurement of the fluctuations in the number of muons in extensive air showers produced by ultrahigh energy cosmic rays. We find that the measured fluctuations are in good agreement with predictions from air shower simulations. This observation provides new insights into the origin of the previously reported deficit of muons in air shower simulations and constrains models of hadronic interactions at ultrahigh energies. Our measurement is compatible with the muon deficit originating from small deviations in the predictions from hadronic interaction models of particle production that accumulate as the showers develop.

Ovarian reserve may influence the outcome of bone mineral density in patients with long-term use of dienogest. SAGE Open Med 2021; 9:20503121211005992. [PMID: 35154758 PMCID: PMC8826102 DOI: 10.1177/20503121211005992] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2021] [Accepted: 03/05/2021] [Indexed: 11/17/2022] Open
Abstract
Objective: Long-term administration of dienogest, which is known to have effect on bone mineral density, is frequently done in patients with endometriosis and adenomyosis, but a few studies focused on the bone mineral density changes after finishing the long-term therapy. This study aimed to reveal the factors that adversely affect lumbar bone mineral density. Method: Fifty-seven premenopausal women who visited our hospital were diagnosed as either endometriosis or adenomyosis, and they were treated by dienogest for more than 115 weeks (26.5 months). Based on a previous report, bone mineral density changes less than 2% was categorized as the osteopenic group ( n = 30), and the others were assigned to the unchanged group ( n = 27). Bone mineral density was measured at the lumbar spine using dual-energy X-ray absorptiometry. A representative ovarian reserve marker, endogenous estradiol levels, and follicle-stimulating hormone levels were measured over time and were compared between the osteopenic and unchanged groups. Result: Duration of dienogest intake was 59.5 months (osteopenic group) versus 57.5 months (unchanged group). These patients experienced ovarian surgeries in a similar frequency, but the ovarian reserve in osteopenic group was impaired as suggested by the decline of endogenous estradiol level during intake of dienogest compared to that of unchanged group ( p = 0.0146). Endogenous follicle-stimulating hormone level between osteopenic group and unchanged group did not reach statistically significant difference, although the osteopenic group showed relatively higher level. Conclusion: This study might suggest that decreased ovarian reserve as judged by endogenous estradiol level is a factor that negatively affect bone mineral density, and measurement of endogenous estradiol level during intake of dienogest could have a predictive meaning of future decreased bone mineral density level.

Abstract
We report a measurement of the energy spectrum of cosmic rays above 2.5×10^{18} eV based on 215 030 events. New results are presented: at about 1.3×10^{19} eV, the spectral index changes from 2.51±0.03(stat)±0.05(syst) to 3.05±0.05(stat)±0.10(syst), evolving to 5.1±0.3(stat)±0.1(syst) beyond 5×10^{19} eV, while no significant dependence of spectral features on the declination is seen in the accessible range. These features of the spectrum can be reproduced in models with energy-dependent mass composition. The energy density in cosmic rays above 5×10^{18} eV is [5.66±0.03(stat)±1.40(syst)]×10^{53} erg Mpc^{-3}.

Abstract
Background Dental professionals have so many opportunities to use injection needles and sharp instruments during dental treatment that they face an increased risk of needlestick injuries. This retrospective study reports the utilization and clinical outcomes of occupational post-exposure prophylaxis (PEP) with anti-retroviral agents after being potentially exposed to HIV at the dental departments of Hiroshima University Hospital. Objective This study reports the utilization and clinical outcomes of occupational post-exposure prophylaxis (PEP) with antiretroviral agents after being potentially exposed to HIV at dental departments of Hiroshima University Hospital. Methods Data on the clinical status of HIV-infected source patients and information on HIV-exposed dental professionals from 2007 to 2018 were collected. Results Five dentists with an average experience of 5.6 years (1-15 years) were exposed. The averaged CD4-positive cell number and HIV-RNA load were 1176 (768-1898) /μl and less than 20 copies/ml, respectively, in all the patients. Two of the five HIV exposed dentists received PEP. Three months after the exposures, all of their results were negative in HIV antibody/antigen tests. Conclusion These data might support the concept of “undetectable equals untransmittable”, although HIV exposure in this study was not through sexual transmission.

Abstract
BACKGROUND Intraperitoneal chemotherapy using paclitaxel is considered an experimental approach for treating peritoneal carcinomatosis. This study aimed to determine the recommended dose, and to evaluate the clinical efficacy and safety, of the combination of intravenous gemcitabine, intravenous nab-paclitaxel and intraperitoneal paclitaxel in patients with pancreatic cancer and peritoneal metastasis. METHODS The frequencies of dose-limiting toxicities were evaluated, and the recommended dose was determined in phase I. The primary endpoint of the phase II analysis was overall survival rate at 1 year. Secondary endpoints were antitumour effects, symptom-relieving effects, safety and overall survival. RESULTS The recommended doses of intravenous gemcitabine, intravenous nab-paclitaxel and intraperitoneal paclitaxel were 800, 75 and 20 mg/m2 respectively. Among 46 patients enrolled in phase II, the median time to treatment failure was 6·0 (range 0-22·6) months. The response and disease control rates were 21 of 43 and 41 of 43 respectively. Ascites disappeared in 12 of 30 patients, and cytology became negative in 18 of 46. The median survival time was 14·5 months, and the 1-year overall survival rate was 61 per cent. Conversion surgery was performed in eight of 46 patients, and those who underwent resection survived significantly longer than those who were not treated surgically (median survival not reached versus 12·4 months). Grade 3-4 haematological toxicities developed in 35 of 46 patients, whereas non-haematological adverse events occurred in seven patients. CONCLUSION Adding intraperitoneal paclitaxel had clinical efficacy with acceptable tolerability.

How Different is the Core of ^{25}F from ^{24}O_{g.s.} ? PHYSICAL REVIEW LETTERS 2020; 124:212502.

Abstract
The structure of a neutron-rich ^{25}F nucleus is investigated by a quasifree (p,2p) knockout reaction at 270A MeV in inverse kinematics. The sum of spectroscopic factors of π0d_{5/2} orbital is found to be 1.0±0.3. However, the spectroscopic factor with residual ^{24}O nucleus being in the ground state is found to be only 0.36±0.13, while those in the excited state is 0.65±0.25. The result shows that the ^{24}O core of ^{25}F nucleus significantly differs from a free ^{24}O nucleus, and the core consists of ∼35% ^{24}O_{g.s.}. and ∼65% excited ^{24}O. The result may infer that the addition of the 0d_{5/2} proton considerably changes neutron structure in ^{25}F from that in ^{24}O, which could be a possible mechanism responsible for the oxygen dripline anomaly.

Swelling of Doubly Magic ^{48}Ca Core in Ca Isotopes beyond N=28. PHYSICAL REVIEW LETTERS 2020; 124:102501.

Abstract
Interaction cross sections for ^{42-51}Ca on a carbon target at 280 MeV/nucleon have been measured for the first time. The neutron number dependence of derived root-mean-square matter radii shows a significant increase beyond the neutron magic number N=28. Furthermore, this enhancement of matter radii is much larger than that of the previously measured charge radii, indicating a novel growth in neutron skin thickness. A simple examination based on the Fermi-type distribution, and mean field calculations point out that this anomalous enhancement of the nuclear size beyond N=28 results from an enlargement of the core by a sudden increase in the surface diffuseness of the neutron density distribution, which implies the swelling of the bare ^{48}Ca core in Ca isotopes beyond N=28.

Background
Mitral valve repair is preferred to valve replacement in cases of degenerative mitral regurgitation (MR) due to the lower risk of valve-related complications and operative mortality. In mitral valve repair, annuloplasty is associated with better clinical outcomes. Sizing of the annuloplasty ring with a ring sizer, which should be performed in the end-systolic phase, is performed in diastole during hyperkalaemia cardioplegic arrest. Three-dimensional transoesophageal echocardiography (3D-TEE) allows measurement of the mitral valve while the heart is beating, which is beneficial since the mitral valve size changes throughout the cardiac cycle.
Purpose
To investigate whether 3D-TEE measurements of the mitral valve are effective for preventing recurrent mitral regurgitation (MR) in patients who undergo mitral valve repair for degenerative MR.
Methods
This study retrospectively reviewed 139 patients who underwent mitral annuloplasty for degenerative MR. After 47 patients were excluded, 92 patients were analysed. The inter-commissural (IC) distance and anterior leaflet height of the A2 segment of the mitral valve were measured by 3D-TEE at the end-systolic phase. The annuloplasty ring size and type were selected by surgeons using specific ring sizers. We investigated the association of the IC distance with the size of implanted annulus ring and differences between the size of implanted annulus ring and the IC distance. We also compared the IC distance, the A2 height, and the ratio of A2 height to IC distance between patients with and without recurrent mild-to-moderate MR for 36 months.
Results
There was a significant correlation between the size of the mitral annuloplasty ring and the IC distance (R²=0.7023, p < 0.001). The variety between implanted annulus ring size and IC distance measured by 3D-TEE was shown in Figure1. Eight cases had mild or greater recurrent MR. There was a significant difference in the ratio of A2 height to IC distance between patients with and without recurrent MR (p = 0.006). The A2 height was greater in patients with recurrent MR, but this difference was not significant (p = 0.059).
Conclusions
There was a significant correlation between the size of the mitral annuloplasty ring and the IC distance. Our results demonstrated a higher ratio of A2 height to IC distance in patients with recurrent MR.

Abstract
Background
Stroke and cardiovascular disease are one of the leading causes of death and disability in Japan. In order to investigate current burden, we conduct a population-based registry of cardiovascular disease in Shiga Prefecture, Japan since 2012. We will demonstrate challenges in conduct of the registry study.
Methods
In 2012, we established the Shiga Stroke Registry (SSR), a multicenter population-based registry study designed to build a complete information system for the management of stroke in Shiga Prefecture, Japan. The registry uses local monitoring, combined with remote data collection and quality control systems, to create an integrated surveillance system among a network of all acute care hospitals with neurology/neurosurgery facilities and smaller hospitals with rehabilitation facilities in the region. In 2019, study name has changed to Shiga Stroke and Heart Attack Registry (SSHR) and additional registration of coronary heart disease and aortic disease have started. Each case is reviewed and adjudicated by 2 or more specialists.
Results
In the financial year of 2018 (from April to March), a total of 4809 stroke cases were identified. From December 2018 to April 2019, a total of 515 coronary heart and aortic diseases were identified. A total 10 nurses work full-time for the registry and it takes average of 1 hour to collect information for each patient. Challenges in conduct of the cardiovascular registry involve regulatory and ethical approval, funding, associations with local hospitals, non-standardized hospital diagnosis, staff training for comprehensive data collection including pathophysiology, examination and treatment, and quality control of data collection.
Conclusions
SSHR is a population-based registry of wide range of stroke and cardiovascular disease in Shiga Prefecture, Japan. In order to keep quality of the data, we put a lot of efforts on staff training and quality control.

Abstract
Background The 21-gene recurrence score (RS) (Oncotype DX®; Genomic Health, Redwood City, CA) partitions hormone receptor positive, node negative breast cancers into three risk groups for recurrence. The Anne Arundel Medical Center (AAMC) model has previously been shown to accurately predict RS risk categories using standard pathology data. A pathologic-genomic (P-G) algorithm then is presented using the AAMC model and reserving the RS assay only for AAMC intermediate-risk patients. Patients and methods A survival analysis was done using a prospectively collected institutional database of newly diagnosed invasive breast cancers that underwent RS assay testing from February 2005 to May 2015. Patients were assigned to risk categories based on the AAMC model. Using Kaplan-Meier methods, 5-year distant recurrence rates (DRR) were evaluated within each risk group and compared between AAMC and RS-defined risk groups. Five-year DRR were calculated for the P-G algorithm and compared with DRR for RS risk groups and the AAMC model's risk groups. Results A total of 1268 cases were included. Five-year DRR were similar between the AAMC low-risk group (2.7%, n = 322) and the RS < 18 low-risk group (3.4%, n = 703), as well as between the AAMC high-risk group (22.8%, n = 230) and the RS > 30 high-risk group (23.0%, n = 141). Using the P-G algorithm, more patients were categorized as either low or high risk and the distant metastasis rate was 3.3% for the low-risk group (n = 739) and 24.2% for the high-risk group (n = 272). Using the P-G algorithm, 44% (552/1268) of patients would have avoided RS testing. Conclusions AAMC model is capable of predicting 5-year recurrences in high- and low-risk groups similar to RS. Further, using the P-G algorithm, reserving RS for AAMC intermediate cases, results in larger low- and high-risk groups with similar prognostic accuracy. Thus, the P-G algorithm reliably identifies a significant portion of patients unlikely to benefit from RS assay and with improved ability to categorize risk.

Abstract
The aim of the study was to evaluate the oral environment and the taste function of Japanese HIV-infected patients treated with antiretroviral therapy. Their median age of 73 patients taking anti-HIV drugs was 46 years. The median period of taking anti-HIV drugs was 30 months. The oral condition was evaluated by measurement of oral moisture, amount of saliva secretion, the number of oral bacteria, presence of oral candida, a taste test, and the number of missing teeth. The levels of oral moisture and secreted saliva were significantly lower in the HIV-infected group than in the healthy volunteer (control) group. The HIV-infected group showed a more robust decrease in taste sensation than the control group. The number of missing teeth was significantly higher in the HIV-infected group than in the control group. Furthermore, all of the evaluated oral conditions were worse in the HIV-infected patients whose CD4+ T lymphocyte counts were less than 500/mm3 than in the control group. It became clear that the patients taking anti-HIV drugs, especially the CD4+ count < 500/mm3 group, had a deteriorated oral environment and dysgeusia, suggesting that the management of oral hygiene is necessary to maintain oral health, which leads to systemic health.

Covering the celestial sphere at ultra-high energies: Full-sky cosmic-ray maps beyond the ankle and the flux suppression. EPJ WEB OF CONFERENCES 2019.

Abstract
Despite deflections by Galactic and extragalactic magnetic fields, the distribution of ultra-high energy cosmic rays (UHECRs) over the celestial sphere remains a most promising observable for the identification of their sources. Thanks to a large number of detected events over the past years, a large-scale anisotropy at energies above 8 EeV has been identified, and there are also indications from the Telescope Array and Pierre Auger Collaborations of deviations from isotropy at intermediate angular scales (about 20 degrees) at the highest energies. In this contribution, we map the flux of UHECRs over the full sky at energies beyond each of two major features in the UHECR spectrum – the ankle and the flux suppression -, and we derive limits for anisotropy on different angular scales in the two energy regimes. In particular, full-sky coverage enables constraints on low-order multipole moments without assumptions about the strength of higher-order multipoles. Following previous efforts from the two Collaborations, we build full-sky maps accounting for the relative exposure of the arrays and differences in the energy normalizations. The procedure relies on cross-calibrating the UHECR fluxes reconstructed in the declination band around the celestial equator covered by both observatories. We present full-sky maps at energies above ~ 10 EeV and ~ 50 EeV, using the largest datasets shared across UHECR collaborations to date. We report on anisotropy searches exploiting full-sky coverage and discuss possible constraints on the distribution of UHECR sources.

Abstract
Recently, the application of microwave heating to high-temperature processing has received increased attention. In this study, fly ash containing large amounts of unburnt carbon and sodium chloride was sintered by applying microwaves as part of an investigation of the application of microwave heating to high-temperature processes. Microwave fields were separated by cavities, and pure electrical fields were employed as a heat source. The heating rate and maximum temperature increased with the microwave power, while the fly ash exhibited anomalous heating behavior at 450 °C. In this case, unburnt carbon in the fly ash plays an important role in the microwave absorption properties. At 900-1200 °C, no change was observed in the hardness or composition even when the heating duration was increased. In addition, it was found that the amount of chlorine and carbon in the fly ash decreased as the temperature increased. The chlorine concentration in the sample decreased due to the addition of carbon.

Metabolic tumor volume of metastatic lymph nodes and survival after total laryngectomy in laryngeal and hypopharyngeal cancer. Oral Oncol 2019; 93:107-113. [PMID: 31109690 DOI: 10.1016/j.oraloncology.2019.04.011] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2018] [Revised: 04/10/2019] [Accepted: 04/19/2019] [Indexed: 11/19/2022]
Abstract
OBJECTIVES The prognostic value of metabolic tumor volume (MTV) in locally advanced laryngeal or hypopharyngeal cancer is established in the setting of chemoradiotherapy, while it remains unknown in the setting of upfront total laryngectomy. MATERIALS AND METHODS We retrospectively analyzed 88 patients receiving total laryngectomy and neck dissection, using Cox regression models. RESULTS AND CONCLUSION Variables related to metastatic lymph node were associated with overall survival, whereas those related to primary tumor were not. In multivariable models, MTV of metastatic lymph nodes (N-MTV) as a continuous variable (Akaike's information criterion (AIC), 277.5) was equivalent to pathological nodal status (AIC, 278.2; P = 0.40), and superior to pathological nodal classification as an ordinal variable (AIC, 281.4; P < 0.05) in ability of predicting death. The risk of death was increased by 1.2-fold (95% confidence interval (CI), 1.0-1.4; P = 0.03) every 10-ml increment of N-MTV, while patients with pN+ disease were at a higher risk of death by 2.9-fold (95% CI, 1.0-12.2; P < 0.05) compared with patients with pN0 disease. Using recursive partitioning analysis (RPA), we classified the patients as having a low, intermediate, or high risk of death on the basis of N-MTV and extranodal extension (ENE). This RPA classification system exhibited greater concordance with overall survival than the classification considering pathological nodal status and ENE (AIC, 275.8 versus 281.4; P = 0.02). In the setting of upfront total laryngectomy, N-MTV is a critical predictor of mortality. A staging system in which N-MTV is incorporated may better inform adjuvant treatment decisions.
