Abstract
BACKGROUND Tsukamurella spp. are obligate aerobic, gram-positive, non-motile, and slightly acid-fast bacilli belonging to the Actinomycetes family. They share many characteristics with Nocardia, Rhodococcus, Gordonia, and the rapidly growing Mycobacterium species. Therefore, standard testing may misidentify Tsukamurella spp. as another species. Accurate and rapid diagnosis is critical for proper infection management, but identification of this bacterium is difficult in the standard laboratory setting. CASE PRESENTATION A bloodstream infection caused by a gram-positive bacterium and related to a central venous catheter was identified in an immunocompromised 2-year-old girl. Tsukamurella tyrosinosolvens was identified by modified secA1 sequencing. Antibiotic treatment and removal of the central venous catheter resolved the infection. Inappropriate management of the catheter during an overnight stay outside of the hospital was considered as a possible source of infection. CONCLUSIONS SecA1 sequencing may be a useful diagnostic tool in the identification of T. tyrosinosolvens. Providing proper central venous catheter care instructions to patients, their families, and medical staff is important for infection prevention.

Treatment optimization by monitoring vancomycin concentration in the serum and cerebrospinal fluid in a child with cystoperitoneal shunt-related infection caused by methicillin-resistant Staphylococcus aureus: a case report and literature review. Childs Nerv Syst 2023; 39:3307-3310.

Abstract
BACKGROUND Cerebral ventricular shunt infections caused by methicillin-resistant Staphylococcus aureus (MRSA), especially strains with elevated minimum inhibitory concentration (MIC) values, have a poor prognosis. Monitoring serum vancomycin (VCM) levels with therapeutic drug monitoring and maintaining high VCM concentrations in the cerebrospinal fluid (CSF) are critical to treatment success. However, there have been a few reports about the CSF penetration and the pharmacokinetics of VCM in children. CASE PRESENTATION Here, we report the case of a pediatric patient with cysto-peritoneal shunt-related meningitis caused by MRSA with an MIC of 2 μg/mL. The adequate VCM concentration was maintained by monitoring the VCM concentration in the CSF via the external ventricular drain, and frequent blood taking was avoided. VCM showed a good CSF penetration in our patient, and she was discharged without complications. DISCUSSION Therapeutic drug monitoring of VCM concentration in the CSF may result in successful treatment even if MRSA shows a higher MIC. Therapeutic drug monitoring of VCM concentration in the CSF may also reduce the side effects.

Abstract
We present measurements of the cross section and double-helicity asymmetry A_{LL} of direct-photon production in p[over →]+p[over →] collisions at sqrt[s]=510 GeV. The measurements have been performed at midrapidity (|η|<0.25) with the PHENIX detector at the Relativistic Heavy Ion Collider. At relativistic energies, direct photons are dominantly produced from the initial quark-gluon hard scattering and do not interact via the strong force at leading order. Therefore, at sqrt[s]=510 GeV, where leading-order-effects dominate, these measurements provide clean and direct access to the gluon helicity in the polarized proton in the gluon-momentum-fraction range 0.02<x<0.08, with direct sensitivity to the sign of the gluon contribution.

Abstract
OBJECTIVES The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant emergence preceded a wave of pediatric coronavirus disease 2019 (COVID-19) cases, putting considerable strain on hospitals across Japan. Our study evaluated the pediatric disease burden of COVID-19 in pediatric hospitals. METHODS This retrospective study evaluated all pediatric patients (defined as aged < 21 years) hospitalized with SARS-CoV-2 infection, or as close contacts, at four children's hospitals, between January 1 and May 31, 2022. Clinical characteristics, reasons for admission, and outcome data were analyzed. RESULTS In total, 492 patients (median age 3.0 years; male 58.7%) were included over the study period. Of these, 232 (47.2%) patients had at least one underlying disease. Asymptomatic and mild diseases were common during the study period (n = 451, 91.7%). Social reasons for hospitalization (including a lack of family support at home) accounted for 36.8% (n = 181) of inpatients. The median length of stay was 4.0 days. Fever was the most common symptom (n = 273, 55.5%), followed by upper respiratory (n = 77, 15.7%) and neurological (n = 60, 12.2%) symptoms. Overall, 34 (6.9%) children required invasive mechanical ventilation, 51 (10.4%) were admitted to the pediatric intensive care unit, and two (0.4%) died. COVID-19 vaccination rate was low (n =14/200, 7.0%). CONCLUSIONS The disease burden during the Omicron-predominant period was attributable to asymptomatic and mild infections, and some patients were hospitalized for social reasons. To maintain a medical care system for critically ill patients, each medical facility must play a role according to its function.

Nosocomial meningitis caused by Staphylococcus haemolyticus in a child with neutropenia in the absence of intracranial devices: a case report. BMC Infect Dis 2023; 23:95.

Abstract
BACKGROUND Coagulase-negative staphylococci can cause hospital-acquired infections, especially in immunocompromised hosts. Bacterial meningitis is a potentially fatal infection of the central nervous system, causing high mortality and morbidity. In general, the causative agents of meningitis, coagulase-negative staphylococci, are associated with direct implantation of a foreign body and the presence of a cerebrospinal fluid (CSF) shunt. Here, we describe a case of nosocomial meningitis caused by Staphylococcus haemolyticus in a child with neutropenia who had no intracranial foreign devices. CASE PRESENTATION A 15-year-old boy with relapsed acute myeloid leukemia undergoing chemotherapy through a central venous catheter developed fever on Day 13 post-initiation of chemotherapy. There was no history of implantation of neurosurgical devices. Two blood cultures obtained on Day 14 were positive for Staphylococcus haemolyticus. Clinical improvement was noted, and treatment with vancomycin and removal of the central venous catheter resulted in negative repeat blood cultures on Day 18. However, the patient developed a tendency for somnolence and improper speech, along with persistent fever on Day 26. A lumber puncture was performed on Day 27, resulting in positive culture of Staphylococcus haemolyticus. He was diagnosed with meningitis and the dosage of vancomycin was increased. A repeat CSF culture was positive for Staphylococcus haemolyticus on Day 40, so oral rifampicin was added. CSF findings on Day 46 revealed a low concentration of vancomycin, and treatment was switched from vancomycin plus rifampicin to linezolid. After Day 46, four subsequent cerebrospinal fluid tests of the CSF showed no growth of Staphylococcus haemolyticus. The patient's symptoms were improved on Day 52. Brain and spinal magnetic resonance images was taken and it showed no abnormalities. Linezolid was continued until Day 72. The patient was discharged without any complications on Day 72. CONCLUSIONS To the best of our knowledge, this is the first reported case of Staphylococcus haemolyticus meningitis in a patient without a neurosurgical device. Typical symptoms or signs may be absent in a patient with meningitis who also has neutropenia. Repeated tests of the CSF, and prolonged duration of antibiotics should be considered if atypical pathogens are detected in immunocompromised hosts.

Abstract
Waterhouse-Friderichsen syndrome and central diabetes insipidus are uncommon but potentially fatal endocrine and metabolic diseases. Waterhouse-Friderichsen syndrome is defined as adrenal insufficiency caused by adrenal hemorrhage, which is typically bilateral and most frequently due to meningococcal infection. It is usually diagnosed by necropsy. Central diabetes insipidus in children is often caused by trauma, intracranial lesions, autoimmune diseases, and infections. In addition, it can be caused by mutations in the AVP-NPII gene, although this occurs typically later in childhood rather than in the neonatal period. This report describes a term infant who developed Escherichia coli meningitis, which resulted in septic shock and disseminated intravascular coagulation. Abdominal ultrasound led to an early diagnosis of bilateral adrenal hemorrhage and appropriate treatment with corticosteroids. Symptomatic central diabetes insipidus developed a few days after the onset of meningitis. Intravenous vasopressin was effective in resolving hemodynamic instability. In conclusion, sepsis and meningitis may have severely affected the endocrine system in this patient. Early diagnosis and appropriate treatment for both diseases may have resulted in better clinical outcomes for this patient.

Abstract
Background Schaaf‐Yang syndrome (SYS) is a rare hereditary disease caused by truncating point mutations of the paternal allele of melanoma antigen L2 (MAGEL2), one of five protein‐coding genes within the Prader‐Willi syndrome (PWS) critical domain. SYS shares many clinical and molecular characteristics with PWS but has some distinct features, such as joint contractures and autism. Patients with PWS show abnormal electroencephalography (EEG) patterns. However, there are very few reports on EEG findings in patients with SYS. Methods A SYS patient was included in this study. Detailed neurological examinations and EEG were performed from neonate to infant ages. Sanger sequencing was performed. Results Our patient presented abnormal EEG findings and had diffuse brain dysfunction symptoms including a reduced level of consciousness, diminished spontaneous movements, hypotonia, feeding difficulties, and hypoventilation from early after birth. As she grew older and her background activity of EEG normalized, her neurodevelopmental symptoms remained but improved. Sanger sequencing of this patient revealed a novel, heterozygous c.2005C > T, truncating mutation in the MEGAL2 gene. Conclusions We described an SYS‐associated, time‐dependent, EEG pattern in a patient with SYS. Our findings of longitudinal EEG changes in a patient with SYS revealed a specific pattern of how affected individuals develop brain function.

Abstract
BACKGROUND Pouchitis is one of the major postoperative complications of ulcerative colitis (UC), and it is still difficult to predict the development of pouchitis after ileal pouch-anal anastomosis (IPAA) in UC patients. In this study, we examined whether a deep learning (DL) model could predict the development of pouchitis. METHODS UC patients who underwent two-stage restorative proctocolectomy with IPAA at Keio University Hospital were included in this retrospective analysis. The modified pouchitis disease activity index (mPDAI) was evaluated by the clinical and endoscopic findings. Pouchitis was defined as an mPDAI ≥ 5.860; endoscopic pouch images before ileostomy closure were collected. A convolutional neural network was used as the DL model, and the prediction rates of pouchitis after ileostomy closure were evaluated by fivefold cross-validation. RESULTS A total of 43 patients were included (24 males and 19 females, mean age 39.2 ± 13.2 years). Pouchitis occurred in 14 (33%) patients after ileostomy closure. In less than half of the patients, mPDAI scores matched before and after ileostomy closure. Most of patients whose mPDAI scores did not match before and after ileostomy closure had worse mPDAI scores after than before. The prediction rate of pouchitis calculated by the area under the curve using the DL model was 84%. Conversely, the prediction rate of pouchitis using mPDAI before ileostomy closure was 62%. CONCLUSION The prediction rate of pouchitis using the DL model was more than 20% higher than that using mPDAI, suggesting the utility of the DL model as a prediction model for the development of pouchitis. It could also be used to determine early interventions for pouchitis.

Abstract
OBJECTIVES To examine the relationship between sarcopenia and fecal incontinence in patients with dysphagia. DESIGN Cross-sectional study using the Japanese sarcopenic dysphagia database. SETTING 19 hospitals including 9 acute care hospitals, 8 rehabilitation hospitals, 2 long-term care hospitals, and 1 home visit rehabilitation center. PARTICIPANTS 460 dysphagic patients, aged 20 years and older. MEASUREMENTS Sarcopenia was diagnosed by the 2019 criteria of the Asian Working Group for Sarcopenia. Fecal incontinence was assessed by health care professionals at baseline according to the definition of the Japanese Practice Guidelines for Fecal Incontinence. We examined whether there was a significant difference between the rate of fecal incontinence in patients with/without sarcopenia. Age, sex, type of dwelling, Barthel index, Charlson comorbidity index (CCI), calf circumference, handgrip strength, body mass index, malnourishment, C-reactive protein level, serum albumin level, and delivery of enteral nutrition by nasogastric and/or gastrostomy tube were measured. To examine the relationship between sarcopenia and fecal incontinence, logistic regression analysis was performed with adjustments for age, sex, sarcopenia, CCI, enteral nutrition, and dwelling. RESULTS The mean age of patients was 81 ± 10 years. Of the 460 study patients, 404 (88%) patients had sarcopenia and 104 had fecal incontinence (23%). The rate of fecal incontinence was higher in the sarcopenia group than the non-sarcopenia group (25% vs. 7%, P = 0.003). Logistic regression analysis showed that sarcopenia was independently associated with fecal incontinence (odds ratio: 3.114, 95% confidence interval: 1.045, 9.282). CONCLUSION The prevalence of fecal incontinence was 23% in patients with dysphagia. Sarcopenia was independently associated with fecal incontinence, which suggests the presence of anal sarcopenia. Defecation control should be assessed in patients with sarcopenia.

Abstract
Studying spin-momentum correlations in hadronic collisions offers a glimpse into a three-dimensional picture of proton structure. The transverse single-spin asymmetry for midrapidity isolated direct photons in p^{↑}+p collisions at sqrt[s]=200 GeV is measured with the PHENIX detector at the Relativistic Heavy Ion Collider (RHIC). Because direct photons in particular are produced from the hard scattering and do not interact via the strong force, this measurement is a clean probe of initial-state spin-momentum correlations inside the proton and is in particular sensitive to gluon interference effects within the proton. This is the first time direct photons have been used as a probe of spin-momentum correlations at RHIC. The uncertainties on the results are a 50-fold improvement with respect to those of the one prior measurement for the same observable, from the Fermilab E704 experiment. These results constrain gluon spin-momentum correlations in transversely polarized protons.

Abstract
Treatment strategies for progressive intervertebral-disc degeneration often alleviate pain and other symptoms. With the goal of developing strategies to promote the regeneration of the nucleus pulposus (NP), the present study tried to identify the biological effects of hydrostatic (HP) and osmotic pressures on NP cells. The study hypothesis was that a repetitive regimen of cyclic HP followed by constant HP in high-osmolality medium would increase anabolic molecules in NP cells. Bovine NP cells/clusters were enclosed within semi-permeable membrane pouches and incubated under a regimen of cyclic HP for 2 d followed by constant HP for 1 d, repeated 6 times over 18 d. NP cells showed a significantly increased expression of anabolic genes over time: aggrecan, chondroitin sulfate N-acetylgalactosaminyltransferase 1, hyaluronan synthase 2, collagen type 2 (p < 0.05). In addition, the expression of catabolic or degenerative genes (matrix metalloproteinase 13, collagen type 1) and cellular characteristic genes (proliferating cell nucleic antigen, E-cadherin) was suppressed. The amount of sulfated glycosaminoglycan increased significantly at day 18 compared to day 3 (p < 0.01). Immunostaining revealed deposition of extracellular-matrix molecules and localization of other specific molecules corresponding to their genetic expression. An improved understanding of how cells respond to physicochemical stresses will help to better treat the degenerating disc using either cell- or gene-based therapies as well as other potential matrix-enhancing therapies. Efforts to apply these tissue-engineering and regenerative-medicine strategies will need to consider these important physicochemical stresses that may have a major impact on the survivability of such treatments.

Abstract
Postpartum thyroiditis (PPT) is characterized by mild thyrotoxicosis occurring within one year of parturition commonly followed by transient hypothyroidism. Having genetic background of autoimmune thyroid disorders is a risk factor for it because the immune reactivation during postpartum period is a trigger for PPT. Pandemic of COVID-19: caused by SARS-CoV-2 infection is a global health problem, and occurrence of Graves' disease and Hashimoto's thyroiditis after the viral infection have been reported but occurrence of PPT with COVID-19 has never been reported. A 29-year-old woman developed general fatigue four and a half months after parturition, and was diagnosed as having PPT: one month before, she had COVID-19. Hereafter, we define the date of delivery as Day 0 to make timeline clear. SARS-CoV-2 infection was diagnosed by PCR on Day 103, its disappearance from the upper airway confirmed on Day 124, and the thyroiditis diagnosed on Day 136. She had been euthyroid on Day 0 and 95, but thyrotoxic on Day 136. Serum thyroglobulin (Tg) concentration was normal in the presence of anti-Tg antibody, other thyroid-related autoantibodies were negative, and by ultrasonography, the thyroid gland was normal in size and no evidence of increased vascularity. Thyroid function returned to normal by Day 172 without any specific drug therapy. In conclusion, although a clear causal relationship could not be found, we documented the world's first case of PPT developed following COVID-19.

Abstract
OBJECTIVES To describe the activity and evaluate the quality of the Japanese sarcopenic dysphagia database. DESIGN Cohort registry study. SETTING 19 hospitals including 9 acute care hospitals, 8 rehabilitation hospitals, 2 long-term care hospitals, and 1 home visit rehabilitation team. PARTICIPANTS 467 dysphagic patients, aged 20 years and older. MEASUREMENTS The following indices were assessed at baseline: age, sex, main disease, sarcopenic dysphagia, whole body sarcopenia, Food Intake Level Scale (FILS), malnutrition diagnosed by the Global Leadership Initiative on Malnutrition criteria, oral status assessed by the Revised Oral Assessment Guide or the Oral Health Assessment Tool, activities of daily living assessed by the Functional Independence Measure (FIM) or the Barthel Index (BI), Charlson comorbidity index, C-reactive protein and serum albumin levels, dysarthria, hoarseness, aphasia, pressure ulcers, bladder, bowel, and kidney function, respiratory status, polypharmacy, number of drugs, and involvement of health care professionals and rehabilitation nutrition team. FILS, FIM or BI, and outcome including discharge destination were assessed at follow-up. A simple comparison of cases and evaluation of the quality of data were performed. RESULTS The mean age was 80.4 ± 11.4 yr. The variable input error was 0. The number of patients with missing data was high for estimated glomerular filtration rate, C-reactive protein, serum albumin, skeletal mass index, and tongue pressure. The prevalence of either probable, possible, or no sarcopenic dysphagia was 105 (23%), 182 (39%), or 179 (38%), respectively. Doctors including physiatrists, nurses, physical therapists, and registered dietitians were involved with most patients, while the rehabilitation nutrition team was involved in only 16% of patients. CONCLUSIONS The quality of the database was relatively high. Sarcopenic dysphagia is common in patients with dysphagia.

Abstract
Pseudomonas aeruginosa is a relatively rare cause of neonatal meningitis, and most patients have serious underlying diseases, prematurity, immunodeficiency, or anatomical abnormalities. We report the case of a 7-day-old girl with meningitis caused by P. aeruginosa. She was born full-term and had no immunodeficiency or anatomical abnormalities as far as our investigation ascertained. Through the use of anti-Pseudomonas antibiotics, she recovered without any complications other than a slight hearing disability revealed by audiology testing. P. aeruginosa was also isolated from a domestic sponge brush used to clean her milk bottle. Physicians should consider P. aeruginosa as a possible pathogen of neonatal meningitis even in full-term infants with no immunodeficiency or anatomical abnormalities. Physicians should give advice concerning appropriate hygiene practices to be applied to the neonate's environment.

Abstract
We report a case series of 6 patients with confirmed COVID-19 in Wakayama prefecture, Japan. All 6 of the patients tested positive in pharyngeal swab PCR tests, and 2 of the 6 were still positive at 3 weeks after onset. All of the patients exhibited bilateral ground glass opacities (GGO) on computed tomography (CT). This paper also reports narrative information on the spectrum of symptoms collected directly from the patients. It would be difficult to triage patients with COVID-19 based on the typical symptoms of fever and/or cough, although PCR and CT are definitive in diagnosis.

Abstract
Methotrexate (MTX)-induced intestinal mucosal injury in animals has been studied to understand how MTX can cause gastrointestinal disorders, but the pathogenesis of gastrointestinal disorders is still uncertain. We have attempted to reveal how dietary factors influence intestinal toxicity due to MTX. Mice were fed normal chow (NC) or a high-fat high-sucrose diet (HFHSD) before oral administration of MTX. While MTX significantly decreased the survival rates of mice fed HFHSD, the intestinal epithelial injury was detected. MTX excretion in the feces of mice fed HFHSD was reduced. Change of diets between NC and HFHSD influences the survival. The survival rates of the mice fed a high-sucrose diet or control diet were higher than those fed HFHSD. Higher survival rates were observed in mice fed a high-fat high-sucrose diet modified (HFHSD-M) in which casein was replaced by soybean-derived proteins. The survival rates of mice treated with vancomycin were lower than those administered neomycin. Microbiome and metabolome analyses on feces suggest a similarity of the intestinal environments of mice fed NC and HFHSD-M. HFHSD may modify MTX-induced toxicity in intestinal epithelia on account of an altered MTX distribution as a result of change in the intestinal environment.

Abstract
Abstract
Background
In recent years it has been attempted to use a distal radial artery (DRA) as a puncture site for cardiac catheterization and intervention. A patency of radial artery is important in hemodialysis patients because the radial artery is source as an arteriovenous shunt. However, the incidence of radial artery occlusion (RAO) is not known after DRA puncture.
Purpose
To compare RAO rates after DRA puncture between dialysis and non-dialysis patients.
Method
This was retrospective, observational and single center study. All consecutive 1,533 patients undergoing DRA puncture were analyzed. The primary endpoint is RAO rates. The secondary endpoint is composite bleeding adverse event rates. These endpoints were evaluated by a vascular echocardiography several hours or the next day after the procedure.
Result
Among 1,533 patients, 26 were dialysis patients and 1,504 were non-dialysis patients. 1,386 people (90.5%) succeeded in puncture. Radial artery occlusion occurred in 7 patients (0.4%), all of whom were non-dialysis patients. There was no significant difference of RAO rate in dialysis patients and non-dialysis patients.
Conclusion
When performing DRA puncture, the probability of radial artery occlusion is not higher in dialysis patients than non-dialysis patients. The DRA puncture may be one of the option as puncture site even in dialysis patients.

Abstract
We report on the nuclear dependence of transverse single-spin asymmetries (TSSAs) in the production of positively charged hadrons in polarized p^{↑}+p, p^{↑}+Al, and p^{↑}+Au collisions at sqrt[s_{NN}]=200 GeV. The measurements have been performed at forward rapidity (1.4<η<2.4) over the range of transverse momentum (1.8<p_{T}<7.0 GeV/c) and Feynman x (0.1<x_{F}<0.2). We observed positive asymmetries for positively charged hadrons in p^{↑}+p collisions, and significantly reduced asymmetries in p^{↑}+A collisions. These results reveal a nuclear dependence of TSSAs for charged-hadron production in a regime where perturbative techniques are applicable. These results provide new opportunities to use p^{↑}+A collisions as a tool to investigate the rich phenomena behind TSSAs in hadronic collisions and to use TSSAs as a new handle in studying small-system collisions.

Abstract
Erysipelothrix rhusiopathiae is a major causative organism of swine erysipelas, but the infection has rarely occurred in humans. A soft-tissue infection with this organism is described as “erysipeloid.” Most reported cases in human are related to occupational exposure. Endocarditis is a common complication of E. rhusiopathiae bacteremia in human. We report the case of a previously healthy 52-year-old Japanese female who presented with fever and an inflamed hand after being bitten by a stray cat. Blood culture was positive for E. rhusiopathiae, but no sign of infective endocarditis was observed. It may be prudent to consider E. rhusiopathiae infection in patients with animal bites.

Abstract
Abstract
Background: While Preservation of NAC is concerned to increase the risk of local recurrences in the retroareolar glandular tissue, nipple sparing mastectomy (NSM) is increasing in patients with breast cancer and has been shown to result in better cosmetic outcome and the benefit for quality-of-life. It is necessary to predict accurately NAC involvement in order to select which patients may be candidates to NSM. The distance from the nipple to the tumor (DNT) is proposed as one of the best criteria to select the patient. The purpose of this study is to identify the predictors of NAC involvement retrospectively and to develop a clinical predictive model to select the patients who can be offered preservation of NAC.Methods: A total of 168 patients with primary operable breast cancer who received subcutaneous mastectomy for breast reconstruction at Saitama Medical Center during July 2013 to December 2017 were selected from the hospital's surgical database. NAC involvement was defined by the presence of invasive carcinoma and/or ductal carcinoma in situ at the subareolar margin.
Results: Of the 148 patients who were preserved NAC, 89.9% (133/148) were NAC involvement negative and 10.1% (15/148) were positive in permanent pathological specimens. Of the 20 patients who were resected NAC, NAC involvement positivity was only 50.0% (10/20). This revealed that NAC involvement with a sensitivity (SN) of 40.0%, a specificity (SP) of 93.0%, a positive predictive value (PPV) of 50.0% and a negative predictive value (NPV) of 89.9% (AUC=0.665, 95%CI: 0.5345-0.796). In 140 patients who were performed intraoperative sub-nipple frozen section biopsy, the findings was significantly associated with NAC involvement (P<0.001), and which predict the NAC involvement with a SN of 93.3%, a SP of 89.6%, a PPV of 51.9%, and a NPV of 99.1% (AUC=0.915, 95%CI: 0.835-0.994). In the concordance rate between frozen section findings and definitive pathologic results, DCIS was 53% (9/17), atypical cell was 50% (2/4) and invasive ductal carcinoma was 100% (3/3). Correlation between NAC involvement and clinicopathological factors, tumor size ≥4cm (P<0.001), DNT <1cm by MMG (P=0.002), DNT <1cm by MRI (P<0.001), nipple contrast findings by MRI (P<0.001), tumor in central portion (P<0.001), multicentirc/focal lesion (P<0.001), c(N) positive (P=0.014) were significant relation with NAC involvement. Each predictors were scored 0 or 1, and the total score of 0-3 points was defined as low risk, 4 points as intermediate risk, and 5-7 points as high risk. Depending on this categorized classification, the NAC involvement rate was 3.5% (5/142) in low risk, 68.7% (11/16) in intermediate risk, 90.0% (9/10) in high risk and there was a significant correlation between the risk group and NAC involvement (P <0.001). Notably, assuming that NAC is preserved for low risk patients and is resected for intermediate and high risk patients, NACPI contributes to improve the accuracy of selecting the surgical procedures (SN 80.0%, SP 95.8%, PPV 76.9%, NPV 96.5% (AUC=0.879, 95%CI: 0.784-0.974)).Conclusion: This study suggests that NACPI can help us indicating subcutaneous mastectomy for the breast cancer patients who request preserve NAC with more oncological safety.

Abstract
Asymmetric nuclear collisions of p+Al, p+Au, d+Au, and ^{3}He+Au at sqrt[s_{NN}]=200 GeV provide an excellent laboratory for understanding particle production, as well as exploring interactions among these particles after their initial creation in the collision. We present measurements of charged hadron production dN_{ch}/dη in all such collision systems over a broad pseudorapidity range and as a function of collision multiplicity. A simple wounded quark model is remarkably successful at describing the full data set. We also measure the elliptic flow v_{2} over a similarly broad pseudorapidity range. These measurements provide key constraints on models of particle emission and their translation into flow.

Abstract
Daikenchuto (DKT), a Japanese Kampo medicine, had been reported to increase small intestinal blood flow after liver resection. The aim of this study was to evaluate the effects of early enteral feeding of DKT on portal venous flow and early bowel movement after living donor liver transplantation (LDLT) in an attempt to clarify whether these effects on bowel motility can prevent bacterial and/or fungal translocation. MATERIALS AND METHODS Our prospective study included the consecutive 16 LDLT recipients at Mie University Hospital between June 2006 and September 2009. Sixteen patients were divided into the 2 groups according to enteral feeding starting postoperative day (POD) 1: 8 patients in DKT (15 g/d) administration (DKT group, for 1 week) and 8 patients in tepid water administration (non-DKT group, for 1 week). Portal venous flow, portal venous pressure, presence of fungal infection (serum level of β-D-glucan and fungal polymerase chain reaction assay), time to first food intake, and time to first defecation were serially examined. RESULTS Portal venous flow (mean [SD] velocity) was significantly increased in DKT group compared with non-DKT group: 47.5 (12.9) vs 31.8 (15.4) (P = .04) on POD 1, 46.8 (11.5) vs 28.8 (12.5) (P = .03) on POD 3, and 42.3 (17.2) vs 25.2 (9.0) (P = .05) on POD 5. However, mean (SD) portal venous pressures did not significantly change between the 2 groups. Between the 2 groups (DKT vs non-DKT), the day of first oral intake was not significantly different: 6.9 (2.5) vs 11.3 (8.7) (P = .061), but the mean (SD) day of first defecation was significantly shorter in the DKT group: 3.9 (1.1) vs 5.5 (2.6) (P = .02). Although fungal polymerase chain reaction assay was not significantly different between the 2 groups (4 vs 4 positive cases), the mean (SD) serum levels of β-D-glucan were significantly lower in the DKT group than in the non-DKT group: 9.0 (7.4) vs 18.4 (15.9) pg/mL (P = .04). CONCLUSION Early enteral feeding of DKT after LDLT increased portal vein blood flow without increasing portal vein pressure and stimulated early bowel movement, which in turn might prevent fungal translocation.

Isolated Biliary Fistula After Donor Right Hepatectomy and Its Novel Interventional Treatment: Isolated Liver-Punctured Drainage. Transplant Proc 2018; 50:2885-2888.

Abstract
Isolated biliary leakage is difficult to manage, and afflicted patients often develop refractory fistula. The present case was a 43-year-old male donor whose wife developed acute fulminant liver failure. Computed tomography (CT) volumetry showed that the estimated remnant liver volume was only 394 mL (31%) if his right lobe would be harvested. Since remnant liver volume was marginal, our proposed cut line for the right hepatectomy was set in order to preserve branches of the middle hepatic vein draining segments 4b+8 and 5. Right hepatectomy was performed, but on postoperative day 14, the donor developed fever and right back pain, and enhanced CT showed a 6 cm intra-abdominal abscess at the site of cutting, and we diagnosed it as an isolated biliary fistula since the isolated segment 5/8 was receiving arterial blood supply and exhibiting regrowth. A transabdominal abscess drainage was performed, after which the patient lost 30 to 50 mL of bile juice per day in drainage until 2 months after the drainage procedure. Ethanol injection, acetic acid injection, and transarterial or portal embolization for the isolated liver were proposed, but these all were impossible to carry out because there were no accessible routes. Thus, re-abscess drainage with a 7-French drainage catheter was performed through the isolated liver on postoperative day 53, and the isolated functional liver was punctured to induce liver atrophy. After this drainage, the isolated liver started to shrink and bile output had been stopped. In conclusion, our punctured-liver drainage could be effective for the treatment of isolated biliary fistula, allowing physicians to avoid an invasive additional liver resection or other invasive percutaneous approach using chemical reagents.

Abstract
We report measurements of the nuclear modification factor R_{CP} for charged hadrons as well as identified π^{+(-)}, K^{+(-)}, and p(p[over ¯]) for Au+Au collision energies of sqrt[s_{NN}]=7.7, 11.5, 14.5, 19.6, 27, 39, and 62.4 GeV. We observe a clear high-p_{T} net suppression in central collisions at 62.4 GeV for charged hadrons which evolves smoothly to a large net enhancement at lower energies. This trend is driven by the evolution of the pion spectra but is also very similar for the kaon spectra. While the magnitude of the proton R_{CP} at high p_{T} does depend on the collision energy, neither the proton nor the antiproton R_{CP} at high p_{T} exhibit net suppression at any energy. A study of how the binary collision-scaled high-p_{T} yield evolves with centrality reveals a nonmonotonic shape that is consistent with the idea that jet quenching is increasing faster than the combined phenomena that lead to enhancement.

Comparison of national strategies to reduce meticillin-resistant Staphylococcus aureus infections in Japan and England. J Hosp Infect 2018; 100:280-298. [PMID: 30369423 DOI: 10.1016/j.jhin.2018.06.026] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2018] [Accepted: 06/28/2018] [Indexed: 12/19/2022]
Abstract
BACKGROUND National responses to healthcare-associated infections vary between high-income countries, but, when analysed for contextual comparability, interventions can be assessed for transferability. AIM To identify learning from country-level approaches to addressing meticillin-resistant Staphylococcus aureus (MRSA) in Japan and England. METHODS A longitudinal analysis (2000-2017), comparing epidemiological trends and policy interventions. Data from 441 textual sources concerning infection prevention and control (IPC), surveillance, and antimicrobial stewardship interventions were systematically coded for: (a) type: mandatory requirements, recommendations, or national campaigns; (b) method: restrictive, persuasive, structural in nature; (c) level of implementation: macro (national), meso (organizational), micro (individual) levels. Healthcare organizational structures and role of media were also assessed. FINDINGS In England significant reduction has been achieved in number of reported MRSA bloodstream infections. In Japan, in spite of reductions, MRSA remains a predominant infection. Both countries face new threats in the emergence of drug-resistant Escherichia coli. England has focused on national mandatory and structural interventions, supported by a combination of outcomes-based incentives and punitive mechanisms, and multi-disciplinary IPC hospital teams. Japan has focused on (non-mandatory) recommendations and primarily persuasive interventions, supported by process-based incentives, with voluntary surveillance. Areas for development in Japan include resourcing of dedicated data management support and implementation of national campaigns for healthcare professionals and the public. CONCLUSION Policy interventions need to be relevant to local epidemiological trends, while acceptable within the health system, culture, and public expectations. Cross-national learning can help inform the right mix of interventions to create sustainable and resilient systems for future infection and economic challenges.

Abstract
Objective Involvement of the hypothalamus is rare in patients with systemic lupus erythematosus (SLE). In this study, we measured cerebrospinal fluid (CSF) orexin-A levels in SLE patients with hypothalamic lesions to investigate whether the orexin system plays a role in SLE patients with hypothalamic lesions who present with excessive daytime sleepiness (EDS). Methods Orexin-A levels were measured in CSF from four patients with SLE who presented with hypothalamic lesions detected by MRI. Three patients underwent repeated CSF testing. All patients met the updated American College of Rheumatology revised criteria for SLE. Results Tests for serum anti-aquaporin-4 antibodies, CSF myelin basic protein and CSF oligoclonal bands were negative in all patients. All patients presented with EDS. Low to intermediate CSF orexin-A levels (92-180 pg/ml) were observed in three patients in the acute stage, two of whom (patients 1 and 2) underwent repeated testing and showed increased CSF orexin-A levels, reduced abnormal hypothalamic lesion intensities detected by MRI and EDS dissipation at follow-up. In contrast, CSF orexin-A levels were normal in one patient (patient 4) while in the acute stage and at follow-up, despite improvements in EDS and MRI findings. Patient 4 showed markedly increased CSF interleukin-6 levels (1130 pg/ml) and a slightly involved hypothalamus than the other patients. Conclusions Our findings suggest that the orexinergic system has a role in EDS in SLE patients with hypothalamic lesions. Furthermore, cytokine-mediated tissue damage might cause EDS without orexinergic involvement.
