Abstract
PURPOSE Postoperative shoulder pain is a common problem after laparoscopic surgery. This study aimed to investigate the association between operative side and postoperative shoulder pain following urologic laparoscopic surgery performed in the lateral recumbent position. METHODS This was a retrospective cohort study conducted at a single tertiary care center. A total of 506 patients who underwent urologic laparoscopic surgery (including adrenalectomy, radical nephrectomy, partial nephrectomy, and pyeloplasty) between January 2010 and December 2019 were included. Patients who underwent total nephroureterectomy or resection of other organs were excluded. The primary outcome was the incidence of postoperative shoulder pain. A multivariable logistic regression analysis investigated the association between the operative side and postoperative shoulder pain. RESULTS Among the 506 included patients, there were an equal number of surgeries on the left and right sides. Eighty-eight patients had postoperative shoulder pain. The incidence of postoperative shoulder pain in the left-side group was significantly higher than that in the right-side group (21.3% [54/253] versus 13.4% [34/253], crude odds ratio = 1.75, 95% confidence interval [CI] 1.07-2.89). After adjustment for potential confounders (age, sex, body mass index, operation duration, operative technique, epidural block, peripheral nerve block, American Society of Anesthesiologists physical status classification, and intraoperative rocuronium dose), the left operative side was found to be associated with postoperative shoulder pain (adjusted odds ratio = 1.89, 95% CI 1.15-3.09). CONCLUSION The left operative side is associated with an increased incidence of postoperative shoulder pain after urologic laparoscopic surgery performed in the lateral recumbent position.

Abstract
OBJECTIVES The Future Proofing Study (FPS) was established to examine factors associated with the onset and course of mental health conditions during adolescence. This paper describes the design, methods, and baseline characteristics of the FPS cohort. METHODS The FPS is an Australian school-based prospective cohort study with an embedded cluster-randomized controlled trial examining the effects of digital prevention programs on mental health. Data sources include self-report questionnaires, cognitive functioning, linkage to health and education records, and smartphone sensor data. Participants are assessed annually for 5 years. RESULTS The baseline cohort (N = 6388, M = 13.9 years) is broadly representative of the Australian adolescent population. The clinical profile of participants is comparable to other population estimates. Overall, 15.1% of the cohort met the clinical threshold for depression, 18.6% for anxiety, 31.6% for psychological distress, and 4.9% for suicidal ideation. These rates were significantly higher in adolescents who identified as female, gender diverse, sexuality diverse, or Aboriginal and/or Torres Strait Islander (all ps < 0.05). CONCLUSIONS This paper provides current and comprehensive data about the status of adolescent mental health in Australia. The FPS cohort is expected to provide significant insights into the risk, protective, and mediating factors associated with development of mental health conditions during adolescence.

Abstract
BACKGROUND Depression is common during adolescence and is associated with adverse educational, employment, and health outcomes in later life. Digital programs are increasingly being implemented in schools to improve and protect adolescent mental health. Although digital depression prevention programs can be effective, there is limited knowledge about how contextual factors influence real-world delivery at scale in schools. OBJECTIVE The purpose of this study was to examine the contextual factors that influence the implementation of the Future Proofing Program (FPP) from the perspectives of school staff. The FPP is a 2-arm hybrid type 1 effectiveness-implementation trial evaluating whether depression can be prevented at scale in schools, using an evidence-based smartphone app delivered universally to year 8 students (13-14 years of age). METHODS Qualitative interviews were conducted with 23 staff from 20 schools in New South Wales, Australia, who assisted with the implementation of the FPP. The interviews were guided by our theory-driven logic model. Reflexive thematic analysis, using both deductive and inductive coding, was used to analyze responses. RESULTS Staff perceived the FPP as a novel ("innovative approach") and appropriate way to address an unmet need within schools ("right place at the right time"). Active leadership and counselor involvement were critical for planning and engaging; teamwork, communication, and staff capacity were critical for execution ("ways of working within schools"). Low student engagement and staffing availability were identified as barriers for future adoption and implementation by schools ("reflecting on past experiences"). CONCLUSIONS Four superordinate themes pertaining to the program, implementation processes, and implementation barriers were identified from qualitative responses by school staff. On the basis of our findings, we proposed a select set of recommendations for future implementation of digital prevention programs delivered at scale in schools. These recommendations were designed to facilitate an organizational change and help staff to implement digital mental health programs within their schools.

Abstract
BACKGROUND When COVID-19 spread to Australia in January 2020, many communities were already in a state of emergency from the Black Summer bushfires. Studies of adolescent mental health have typically focused on the effects of COVID-19 in isolation. Few studies have examined the impact of COVID-19 and other co-occurring disasters, such as the Black Summer bushfires in Australia, on adolescent mental health. METHODS We conducted a cross-sectional survey to examine the impact of COVID-19 and the Black Summer bushfires on the mental health of Australian adolescents. Participants (N = 5866; mean age 13.61 years) answered self-report questionnaires about COVID-19 diagnosis/quarantine (being diagnosed with and/or quarantined because of COVID-19) and personal exposure to bushfire harm (being physically injured, evacuated from home and/or having possessions destroyed). Validated standardised scales were used to assess depression, psychological distress, anxiety, insomnia, and suicidal ideation. Trauma related to COVID-19 and the bushfires was also assessed. The survey was completed in two large school-based cohorts between October 2020 and November 2021. RESULTS Exposure to COVID-19 diagnosis/quarantine was associated with increased probability of elevated trauma. Exposure to personal harm by the bushfires was associated with increased probability of elevated insomnia, suicidal ideation, and trauma. There were no interactive effects between disasters on adolescent mental health. Effects between personal risk factors and disasters were generally additive or sub-additive. CONCLUSIONS Adolescent mental health responses to community-level disasters are multi-faceted. Complex psychosocial factors associated with mental ill health may be relevant irrespective of disaster. Future research is needed to investigate synergistic effects of disasters on young mental health.

Abstract
Objective As direct jejunal feeding often causes great fluctuation in glucose levels, continuous or slow infusion is recommended for jejunal tube-fed patients. However, continuous feeding results in prolonged immobility and the loss of activities of daily living. We investigated whether or not intermittent feeding of a low-carbohydrate high-monounsaturated fatty acid (LC/HM) nutrient formula reduces glucose fluctuation in patients who have undergone jejunotomy. Methods Ten bed-ridden non-diabetic patients receiving enteral feeding via a jejunostomy tube were enrolled in this study. LC/HM formula and standard control formula were infused in cross-over order for each patient at a speed of 160 kcal/h. Blood glucose levels were monitored by a continuous glucose monitoring system during the investigation period. Results The mean and standard deviation of the glucose concentrations and mean amplitude of glucose excursion (MAGE) were markedly lower while receiving LC/HM formula than while receiving control standard formula (104 vs. 136 mg/dL, 18.1 vs. 58.1 mg/dL, 50.8 vs. 160 mg/dL, respectively). The post-infusion hyperglycemia [area under the curve (AUC) >140 mg/dL] and peak value of the glucose level were also significantly lower in patients fed LC/HM than the control (25.7 vs. 880 mg・h/dL and 153 vs. 272 mg/dL, respectively). Reactive hypoglycemia (AUC <70 mg/dL) was also significantly lower (0.63 vs. 16.7 mg・h/dL) and the minimum value of the glucose level higher (78.4 vs. 61.8 mg/dL) in patients fed LC/HM than the control. Conclusion The LC/HM formula is considered to markedly inhibit glycemic spikes and prevent rebound hypoglycemia in patients who receive enteral feeding after jejunostomy.

Abstract
Background Appropriate pain management is essential to improve the postoperative recovery after total hip arthroplasty (THA). Various case reports have indicated that anterior quadratus lumborum block (QLB) provides effective postoperative analgesia in lower limb surgeries. However, few randomized controlled trials have confirmed the efficacy of anterior QLB for lower limb surgeries. The aim of this single-center, double-blind, randomized controlled trial is to confirm the efficacy of anterior QLB for postoperative recovery after THA. Methods The participants will be randomly assigned to either the anterior QLB or placebo groups, using a set of random numbers for the allocation sequence. Only pharmacists will be aware of the allocations; other investigators will be blinded until study completion. After induction of general anesthesia, anterior QLB will be performed by using 0.25% levobupivacaine or normal saline. Fentanyl will be administered according to blood pressure change during the surgery. The primary outcome will be the quality of recovery 40 score (QoR-40). Secondary outcomes will include the visual analog scale score of pain intensity at rest and movement, intraoperative and postoperative doses of fentanyl, and incidence of postoperative nausea and vomiting. Statistical analysis will be performed by using the Student’s t test, Mann–Whitney U test, and Fisher’s exact test as appropriate. A P value of less than 0.05 will be considered statistically significant. Discussion The results of our study will reveal whether anterior QLB is effective for postoperative recovery after THA.

Abstract
Abstract
Introduction
The presence of atrial fibrillation (AF) in patients with reduced left ventricular ejection fraction (LVEF) is associated with increased risks of mortality and hospitalization for heart failure (HF). Although prior studies reported that catheter ablation (CA) for AF in low LVEF patients reduced risks of all-cause mortality and HF hospitalization, the predictors of worsening HF after ablation has not been adequately evaluated.
Purpose
The purpose of this study was to investigate the impact of improvement in LVEF after AF ablation on the incidence of subsequent HF hospitalization in patients with low LVEF.
Methods
The Kansai Plus Atrial Fibrillation (KPAF) Registry is a multicenter registry enrolling 5,013 consecutive patients undergoing first-time ablation for AF. The current study population consisted of 1,031 patients with reduced LVEF of <60%. We divided the study population into 3 groups according to LVEF at follow-up; 678 patients (65.8%) with improved LVEF (≥5 U change in LVEF), 288 patients (27.9%) with unchanged LVEF (−5 U ≤ change in LVEF <5 U) and 65 patients (6.3%) with worsened LVEF (<−5 U change in LVEF).
Results
During the median follow-up of 1067 [879–1226] days, patients improved LVEF had lower rate of HF hospitalization, compared with those with unchanged and worsened LVEF (2.1%, 8.0%, and 21.5%, respectively, P<0.0001). Recurrent atrial tachyarrhythmias were documented in 43.5%, 47.2% and 67.7%, respectively (P=0.0008).

Conclusion
Among patients with reduced LVEF undergoing AF ablation, patients with subsequently improved LVEF in association with maintained sinus rhythm had markedly lower risk of HF hospitalization during follow-up as compared with those with unchanged or worsened LVEF.

Abstract
Background: Music therapy (MT) may exert beneficial preventive effects in frail elderly individuals in psychophysiological health. Objectives: One hundred and fifteen frail elderly individuals (65–89 years old) participated. Methods: Subjects were randomly divided into 2 groups for a controlled crossover trial. The MT-first group participated in group sessions of 45–50 min conducted by a certified music therapist for 12 weeks, followed by a 12-week waiting period. The waiting-first group participated in the reverse order. Cognitive function was assessed by the Verbal Fluency Test (VFT) and Yamaguchi Kanji Symbol Substitution Test (YKSST). Physical function was assessed by the Timed Up and Go test (TUG). Psychophysical health was assessed by the Geriatric Depression Scale 15-item version (GDS-15), General Health Questionnaire 12-item version (GHQ-12), Instrumental Activity of Daily Living (IADL) scale, and Life Space Assessment (LSA) scale. We also evaluated the outcome of MT using the Clinical Global Impressions of Improvement (CGI-I) scale. Results: After 12 weeks of MT, significant improvements were observed in TUG, GDS-15, and GHQ-12 scores. However, no improvements were noted in other scores. CGI-I scores revealed the significant benefits of MT. Conclusions: MT may improve physical function, depressive mood, and quality of life in frail elderly individuals.

Abstract
Previous screening of a single-gene knockout library consisting of 3,908 disrupted-mutant strains allowed us to identify 51 thermotolerant genes that are essential for survival at a critical high temperature (CHT) in Escherichia coli [Murata M, Fujimoto H, Nishimura K, Charoensuk K, Nagamitsu H, Raina S, Kosaka T, Oshima T, Ogasawara N, Yamada M (2011) PLoS ONE 6: e20063]. In this study, we identified another 21 thermotolerant genes. E. coli thus has 72 thermotolerant genes in total. The genes are classified into 8 groups: genes for energy metabolism, outer membrane organization, DNA double-strand break repair, tRNA modification, protein quality control, translation control, cell division and transporters. This classification and physiological analysis indicate the existence of fundamental strategies for survival at a CHT, which seems to exclude most of the heat shock responses.

Abstract
Abstract
Background: Obesity and insulin resistance are associated with inferior levels of chemosensitivity and overall prognosis for breast cancer (BC) treatment. Recent studies suggest that the quality and quantity of visceral adipose tissue (VAT) play a significant role in adipocyte function, and are related to insulin resistance. We therefore tested the hypothesis that high amount and low quality of VAT worsen treatment outcomes via insulin resistance mechanisms.
Patients and Methods: We examined two independent studies: a cross-sectional study (cohort 1) and a retrospective study (cohort 2). Cohort 1 included 106 women with early-stage BC who were undergoing surgery. Patients with normal weight (17.5< body mass index [BMI, kg/m2] ≤25, n = 53) and overweight/obese patients (BMI >25, n = 53) were selected by a pair-matching method. Insulin resistance was evaluated by HOMA-R: fasting insulin (microU/L) × fasting glucose (nmol/L)/22.5. And insulin-like growth factor (IGF) family including IGF-1 and IGF-binding protein 3 (IGFBP3) were measured before beginning treatment. The amounts of visceral fat (aVAT) was measured by 3-dimensional volumetric software using the stocked computed tomography (CT) imaging data. The quality of VAT was assessed based on the mode value of CT Hounsfield Unit of VAT (VAT-HU) at navel level of CT axial view. The association between the former variables and the quality and quantity of VAT was analyzed. Cohort 2 included 271 patients who received chemotherapy in the neo-adjuvant (NAC) or adjuvant setting. Imaging analysis was performed in the same way, and the association between those values and survival outcome after chemotherapy was analyzed by retrospective chart review.
Results: In cohort 1, aVAT was significantly correlated with serum insulin and HOMA-R levels (Pearson's R 0.44 and 0.42, respectively; P<0.05). On comparing the two groups divided by BMI, the levels of IGF-1 and IGFBP3 were not significantly different between the normal weight and the overweight/obese groups (P = 0.31 and 0.77, respectively). However, the overweight/obese group demonstrated significantly higher HOMA-R (P<0.05). In cohort 2, aVAT was significantly correlated with BMI (P<0.05). In a multivariate analysis, pathological complete responses were not associated with aVAT (P = 0.60). After a median follow-up of 112 months, tertile stratification revealed that the third tertile of aVAT had a significantly shorter distant disease free survival (DDFS) in the NAC setting (p<0.05). When adjusted by covariates in the Cox proportional regression model, aVAT and VAT-HU demonstrated significant contribution to a worsened DDFS ([p<0.05, hazard ratio {HR} 1.39; 95% confidence interval {CI} 1.11 to 1.75] and [p<0.05, HR 1.20, 95% CI 1.01 to 1.43], respectively).
Conclusions: Our study found that high amounts and low quality of VAT worsen treatment outcomes. Furthermore, we found that insulin resistance was related to those two factors. Although further validation is needed, our present work suggests the importance of evaluating the quality and quantity of visceral fat for estimating insulin resistance and treatment outcomes after chemotherapy for patients with early-stage BC.

Abstract
UNLABELLED WHAT IS KNOWN ON THE SUBJECT?: There is a developing body of research on violence in healthcare workplaces. Although psychiatric visiting nurses (PVNs) are an important group of professionals who provide medical services for people with mental disorders live in the community, little is known about the experiences and characteristics of violence exposure among PVNs, or the characteristics and work situations of PVNs related to violence exposure. WHAT THIS STUDY ADDS TO EXISTING KNOWLEDGE?: Approximately 40% of participants were exposed to violence during the previous 12 months; approximately 50% had been exposed during their PVN careers in PVN settings. The most frequent violence was verbal abuse. Longer career length as a PVN and greater number of visits per month were both positively associated with verbal abuse during the previous 12 months. Twenty-eight of the 34 participants (83%) who completed the IES-R-J survey had some residual psychological distress, and two (6%) had a potentially high risk of posttraumatic stress disorder. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: In devising policies and strategies against violence, PVN organizations and administrators should consider the characteristics of the violence, especially verbal abuse, as well as the characteristics and work situations of PVNs that are related to verbal abuse. Furthermore, they might provide relevant information on violence in PVN settings within their violence-prevention manuals or education. It would be important to provide support and to construct a safe workplace environment for PVNs who are experiencing residual psychological distress. ABSTRACT Introduction Psychiatric visiting nurses (PVNs) play a crucial role by providing medical services for community-living individuals with mental disorders in Japan. However, little is known about violence towards PVNs. Aim This cross-sectional study investigated violence during visits and the resulting psychological effects for PVNs. Methods PVNs were assessed using a violence exposure questionnaire and the Impact of Event Scale-Revised (IES-R-J); a measure of posttraumatic distress. Result Thirty-eight (41%) of 94 participants had experienced violence during the previous 12 months and 49 (53%) over their entire career. The most frequent violence was verbal abuse. Career length as a PVN and number of visits per month were significantly positively associated with verbal abuse during the previous 12 months. The IES-R-J scores indicated 28 of the 34 participants who completed the questionnaire exhibited psychological distress for the most traumatic violence during their career and two had a potentially high risk of posttraumatic stress disorder. Discussion and Implications Policies and strategies aimed at reducing violence in PVN settings should be developed according to characteristics of the violence, as well as the characteristics and work situation of PVNs. Furthermore, the provision of support and a safe workplace environment would be important for PVNs with residual psychological distress.

Abstract
This study evaluated the accuracy and reproducibility of a human portable blood glucose meter (PBGM) for canine and feline whole blood. Reference plasma glucose values (RPGV) were concurrently measured using glucose oxidation methods. Fifteen healthy dogs and 6 healthy cats were used for blood sampling. Blood glucose concentrations and hematocrits were adjusted using pooled blood samples for our targeted values. A positive correlation between the PBGM and RPGV was found for both dogs (y = 0.877, x = -24.38, r = 0.9982, n = 73) and cats (y = 1.048, x = -27.06, r = 0.9984, n = 69). Acceptable results were obtained in error grid analysis between PBGM and RPGV in both dogs and cats; 100% of these results were within zones A and B. Following ISO recommendations, a PBGM is considered accurate if 95% of the measurements are within ± 15 mg/dl of the RPGV when the glucose concentration is <100 mg/dl and within ±15% when it is ≥100 mg/dl; however, small numbers of samples were observed inside the acceptable limits for both dogs (11%, 8 of 73 dogs) and cats (39%, 27 of 69 cats). Blood samples with high hematocrits induced lower whole blood glucose values measured by the PBGM than RPGV under hypoglycemic, normoglycemic, and hyperglycemic conditions in both dogs and cats. Therefore, this device is not clinically useful in dogs and cats. New PBGMs which automatically compensate for the hematocrit should be developed in veterinary practice.

Abstract
A 51-year-old man presented with a nonpulsatile anterior neck mass which suggested a thyroglossal duct cyst. At CT a small cystic mass was revealed. The mass contained a well-defined, crescent-shaped, low-density area with homogeneous contrast enhancement. On MR T2-weighted spin-echo and gradient-echo images the mass was as hyperintense as the neck vessels. Angiography and operation confirmed an aneurysm of the left superior thyroid artery with a mural thrombus.

Abstract
UNLABELLED Essentials Epithelial cell apoptosis is critical in the pathogenesis of idiopathic pulmonary fibrosis. Protein S, a circulating anticoagulant, inhibited apoptosis of lung epithelial cells. Overexpression of protein S in lung cells reduced bleomycin-induced pulmonary fibrosis. Intranasal therapy with exogenous protein S ameliorated bleomycin-induced pulmonary fibrosis. SUMMARY Background Pulmonary fibrosis is the terminal stage of interstitial lung diseases, some of them being incurable and of unknown etiology. Apoptosis plays a critical role in lung fibrogenesis. Protein S is a plasma anticoagulant with potent antiapoptotic activity. The role of protein S in pulmonary fibrosis is unknown. Objectives To evaluate the clinical relevance of protein S and its protective role in pulmonary fibrosis. Methods and Results The circulating level of protein S was measured in patients with pulmonary fibrosis and controls by the use of enzyme immunoassays. Pulmonary fibrosis was induced with bleomycin in transgenic mice overexpressing human protein S and wild-type mice, and exogenous protein S or vehicle was administered to wild-type mice; fibrosis was then compared in both models. Patients with pulmonary fibrosis had reduced circulating levels of protein S as compared with controls. Inflammatory changes, the levels of profibrotic cytokines, fibrosis score, hydroxyproline content in the lungs and oxygen desaturation were significantly reduced in protein S-transgenic mice as compared with wild-type mice. Wild-type mice treated with exogenous protein S showed significant decreases in the levels of inflammatory and profibrotic markers and fibrosis in the lungs as compared with untreated control mice. After bleomycin infusion, mice overexpressing human protein S showed significantly low caspase-3 activity, enhanced expression of antiapoptotic molecules and enhanced Akt and Axl kinase phosphorylation as compared with wild-type counterparts. Protein S also inhibited apoptosis of alveolar epithelial cells in vitro. Conclusions These observations suggest clinical relevance and a protective role of protein S in pulmonary fibrosis.

Regional anesthesia, especially epidural anesthesia, rarely causes involuntary movement Here we present a case of a patient who demonstrated myoclonus-like involuntary movement of the lower limbs during continuous infusion of ropivacaine, fentanyl, and droperidol through the thoracic epidural catheter. This movement disappeared when the epidural infusion was stopped, but reappeared when the epidural infusion was restarted. Naloxone did not eliminate the movement The patient was thereafter discharged uneventfully. This case and other reports in the literature suggest that involuntary movement associated with regional anesthesia is rare and self-limiting. However, careful consideration should be given to exclude other, potentially dangerous complications.

Abstract
Touch-sensitive screen terminals enabling intuitive operation are used as input interfaces in a wide range of fields. Tablet terminals are one of the most common devices with a touch-sensitive screen. They have a feature of good portability, enabling use under various conditions. On the other hand, they require a GUI designed to prevent decrease of usability under various conditions. For example, the angle of fingertip contact with the display changes according to finger posture during operation and how the case is held. When a human fingertip makes contact with an object, the contact area between the fingertip and contact object increases or decreases as the contact angle changes. A touch-sensitive screen detects positions using the change in capacitance of the area touched by the fingertip; hence, differences in contact area between the touch-sensitive screen and fingertip resulting from different forefinger angles during operation could possibly affect operability. However, this effect has never been studied. We therefore conducted an experiment to investigate the relationship between size/spacing and operability, while taking the effect of fingertip contact angle into account. As a result, we have been able to specify the button size and spacing conditions that enable accurate and fast operation regardless of the forefinger contact angle.

Abstract
BACKGROUND The objective of this study was to examine the clinical outcomes of immediate breast reconstruction using perforator flaps from different donor sites, and to characterize the trends among these flaps. METHODS We retrospectively reviewed 136 consecutive patients who underwent immediate breast reconstruction using free flaps after skin-sparing mastectomy (SSM) or nipple-sparing mastectomy (NSM). The whole breast was pathologically analyzed in 5-mm sections. Breast reconstruction was performed using the deep inferior epigastric perforator (DIEP) flap, gluteal artery perforator (GAP) flap, and posterior medial thigh perforator (PMTP) flap. Patient characteristics were compared among donor sites. RESULTS NSM was converted to SSM because of intraoperative subareolar tumor positivity in 7 of 107 patients. Eleven patients had positive margins in permanent sections. All but one patient had a positive horizontal margin in the peripheral direction. The 5-year recurrence-free survival rate was 91.9%. The locoregional recurrence rate was 5.1% with a mean follow-up observation period of 75 months. DEIP, GAP, and PMTP flaps were used in 64 (47.1%), 38 (27.9%), and 34 (25.0%) patients, retrospectively. DIEP flaps were used in older patients and those with a higher body mass index. GAP flaps were used in younger patients. DIEP and GAP flaps were used for larger breasts, and PMTP flaps for smaller breasts. CONCLUSION NSM or SSM with immediate perforator flap breast reconstruction is an oncologically acceptable surgical option. We believe that age, desire to have children, body mass index, and excised breast volume are valuable factors for selecting the optimal donor site.

Abstract
Candida glabrata was continuously isolated in cultured urine samples from a subject with thrombotic thrombocytopenic purpura. Yeast-like fungal phagocytosis found in gram staining led to agents being tested for antifungal susceptibility, revealing hyposensitivity to micafungin (MCFG) of MIC < 2 mg/mL. MCFG administered for 10 days failed to cure C. glabrata infection. To clarify why hyposensitivity occurred, we analyzed the FKS gene sequence using the PCR, finding a deficit of 3 bases coding phenylalanine at FKS2 gene amino acid 659. MCFG hyposensitivity may thus occur in long-term candin-class anti-fungal agent treatment. Candin-class agents have potent anti-fungal activity with fewer adverse effects and are widely used clinically. Hyposensitivity due to resistant C. glabrata species showed thus be considered in fungal infection treatment.

Abstract
Two α-1,3-glucanase isozymes, designated as α-1,3-glucanase 1 (Agl-FH1) and α-1,3-glucanase 2 (Agl-FH2), were purified from the culture medium of Paenibacillus glycanilyticus FH11. Agl-FH1 and Agl-FH2 exhibited similar characteristics such as optimal pH, pH stability, optimal temperature, thermostability, and molecular masses on SDS-PAGE. However, their hydrolysis products of α-1,3-glucan varied somewhat. Agl-FH1 hydrolyzed α-1,3-glucan into a mixture of maltotriose and maltotetraose, and maltotetraose was the major hydrolysis product of Agl-FH2. N-terminal amino acid sequence analysis and LC-MS/MS analysis of trypsin digested fragments revealed several differences between the amino acid sequences of Agl-FH1 and Agl-FH2. Genes of Agl-FH1 and Agl-FH2 were subcloned into an expression plasmid, and both enzymes were successfully expressed in Escherichia coli. The recombinant Agl-FH1 and Agl-FH2 exhibited the same enzymatic properties as those of each wild-type enzyme, and both of the recombinants showed the activity on the protoplast formation of Schizophyllum commune mycelia. A great diversity was detected in the C-terminal region of family 87 α-1,3-glucanases. Compared with Agl-FH2 which is highly sequence-related to the known α-1,3-glucanases, the C-terminal region of Agl-FH1 has only slight similarity to them (approximately 20% identity). Our analysis revealed that Agl-FH1 was the first member of a new subgroup of family 87 α-1,3-glucanases.

Abstract
BACKGROUND This study aimed to determine the clinical benefit of neoadjuvant methotrexate, doxorubicin, vinblastine, and cisplatin (MVAC) in patients with muscle-invasive bladder cancer (MIBC) treated with radical cystectomy. PATIENTS AND METHODS Patients with MIBC (T2-4aN0M0) were randomised to receive two cycles of neoadjuvant MVAC followed by radical cystectomy (NAC arm) or radical cystectomy alone (RC arm). The primary end point was overall survival (OS). Secondary end points were progression-free survival, surgery-related complications, adverse events during chemotherapy, proportion with no residual tumour in the cystectomy specimens, and quality of life. To detect an improvement in 5-year OS from 45% in the RC arm to 57% in the NAC arm with 80% power, 176 events were required per arm. RESULTS Patients (N = 130) were randomly assigned to the RC arm (N = 66) and the NAC arm (N = 64). The patient registration was terminated before reaching the initially planned number of patients because of slow accrual. At the second interim analysis just after the early stoppage of patient accrual, the Data and Safety Monitoring Committee recommended early publication of the results because the trial did not have enough power to draw a confirmatory conclusion. OS of the NAC arm was better than that of the RC arm, although the difference was not statistically significant [hazard ratio 0.65, multiplicity adjusted 99.99% confidence interval 0.19-2.18, one-sided P = 0.07]. In the NAC arm and the RC arm, 34% and 9% of the patients had pT0, respectively (P < 0.01). In subgroup analyses, OS in almost all subgroups was in favour of NAC. CONCLUSIONS This trial showed a significantly increased pT0 proportion and favourable OS of patients who received neoadjuvant MVAC. NAC with MVAC can still be considered promising as a standard treatment. UMIN CLINICAL TRIALS REGISTRY IDENTIFIER C000000093.

Abstract
BACKGROUND Apart from its role in the coagulation system, thrombin plays an important role in the inflammatory response through its protease-activated receptors (PARs). However, the role of thrombin in the immune response is not clear. OBJECTIVE To evaluate whether thrombin has a modulatory role in allergic bronchial asthma. METHODS Bronchial asthma was induced in mice by intraperitoneal sensitization and inhalation challenge with ovalbumin. Thrombin or its inhibitors were administered by inhalation before each allergen challenge. RESULTS Mice with low but sustained coagulation activation had reduced allergic inflammation, and allergic asthma was inhibited by low doses of thrombin but worsened by high doses. Allergic asthma was worsened by antithrombin, argatroban, hirudin, and anti-thrombomodulin antibody. Mice with a higher level of an inhibitor of both thrombin and activated protein C had worse disease. Heterozygous PAR-1 mice had less allergic inflammation, but PAR-1 agonist worsened it. Allergic bronchial inflammation was worsened in mice that received adoptive transfer of PAR-1 agonist-treated Th2 cells as compared with controls. Low levels of thrombin suppressed the maturation and secretion of cytokines in dendritic cells, but high levels enhanced this. CONCLUSIONS The effects of thrombin on allergic asthma are dose-dependent, with detrimental effects at high doses and protective effects at low doses. These data demonstrate that thrombin modulates the outcome in allergic bronchial asthma.

Abstract
Compared with the knowledge of maternal care, much less is known about the factors required for paternal parental care. Here we report that new sires of laboratory mice, though not spontaneously parental, can be induced to show maternal-like parental care (pup retrieval) using signals from dams separated from their pups. During this interaction, the maternal mates emit 38-kHz ultrasonic vocalizations to their male partners, which are equivalent to vocalizations that occur following pheromone stimulation. Without these signals or in the absence of maternal mates, the sires do not retrieve their pups within 5 min. These results show that, in mice, the maternal parent communicates to the paternal parent to encourage pup care. This new paradigm may be useful in the analysis of the parental brain during paternal care induced by interactive communication. Parental responsibilities in mice are usually carried out by the mother of the pups. In this study, the authors show that when mothers are separated from their mouse pups, they emit ultrasonic vocalizations to their male partners, who respond by administering paternal care to the pups.

Abstract
Like other fields of medicine, robotics and mechanization might be introduced into endovascular coil embolization of intracranial aneurysms for effective treatment. We have already reported that coil insertion force could be smaller and more stable when the coil delivery wire is driven mechanically at a constant speed. Another background is the difficulty in synchronizing operators' minds and hands when two operators control the microcatheter and the coil respectively. We have therefore developed a mechanical coil insertion system enabling a single operator to insert coils at a fixed speed while controlling the microcatheter. Using our new system, the operator manipulated the microcatheter with both hands and drove the coil using foot switches simultaneously. A delivery wire force sensor previously reported was used concurrently, allowing the operator to detect excessive stress on the wire. In vitro coil embolization was performed using three methods: simple mechanical advance of the coil; simple mechanical advance of the coil with microcatheter control; and driving (forward and backward) of the coil using foot switches in addition to microcatheter control. The system worked without any problems, and did not interfere with any procedures. In experimental coil embolization, delivery wire control using the foot switches as well as microcatheter manipulation helped to achieve successful insertion of coils. This system could offer the possibility of developing safer and more efficient coil embolization. Although we aim at total mechanization and automation of procedures in the future, microcatheter manipulation and synchronized delivery wire control are still indispensable using this system.

Abstract
H2AX is an important factor for chromatin remodeling to facilitate accumulation of DNA damage-related proteins at DNA double-strand break (DSB) sites. In order to further understand the role of H2AX in the DNA damage response (DDR), we attempted to identify H2AX-interacting proteins by proteomics analysis. As a result, we identified nucleolin as one of candidates. Here, we show a novel role of a major nucleolar protein, nucleolin, in DDR. Nucleolin interacted with γ-H2AX and accumulated to laser micro-irradiated DSB damage sites. Chromatin Immunoprecipitation assay also displayed the accumulation of nucleolin around DSB sites. Nucleolin-depleted cells exhibited repression of both ATM-dependent phosphorylation following exposure to γ-ray and subsequent cell cycle checkpoint activation. Furthermore, nucleolin-knockdown reduced HR and NHEJ activity and showed decrease in IR-induced chromatin accumulation of HR/NHEJ factors, agreeing with the delayed kinetics of γ-H2AX focus. Moreover, nucleolin-knockdown decreased MDC1-related events such as focus formation of 53 BP1, RNF168, phosphorylated ATM, and H2A ubiquitination. Nucleolin also showed FACT-like activity for DSB damage-induced histone eviction from chromatin. Taken together, nucleolin could promote both ATM-dependent cell cycle checkpoint and DSB repair by functioning in an MDC1-related pathway through its FACT-like function.

Abstract
Candida glabrata was continuously isolated in cultured urine samples from a subject with thrombotic thrombocytopenic purpura. Yeast-like fungal phagocytosis found in gram staining led to agents being tested for antifungal susceptibility, revealing hyposensitivity to micafungin (MCFG) of MIC <2 mg/mL. MCFG administered for 10 days failed to cure C. glabrata infection. To clarify why hyposensitivity occurred, we analyzed the FKS gene sequence using the PCR, finding a deficit of 3 bases coding phenylalanine at FKS2 gene amino acid 659. MCFG hyposensitivity may thus occur in long-term candin-class anti-fungal agent treatment. Candin-class agents have potent anti-fungal activity with fewer adverse effects and are widely used clinically. Hyposensitivity due to resistant C. glabrata species showed thus be considered in fungal infection treatment.

Abstract
AbstractMultilayered thin films were deposited on pure Al substrate test bars for in situ scanning electron microscope (SEM) microtensile deformation. The films consisted of a TiN layer covered by either SiO2 or W. Deformation of the samples showed that the TiN film dominated cracking events and caused cracking in the W to occur at lower critical stress values than previously reported. Crack deflections along the TiN-W interface were also seen. W film strain was measured by X-ray diffraction before and after testing to look at the effect of cracking and deformation on stress in this film.

Abstract
ABSTRACTThe strain energy release rates for the converging decohesion crack in a multilayered film on a substrate have been calculated using the finite element method. The results for the energy release rate as a function of the intrinsic stress, the thickness of the superlayer and the modulus ratio will be presented. A simple functional form for the results will be shown. The effects of plasticity of the thin metal layer on the energy release rate have been examined. The results show that the effect of plastic deformation is not significant for the converging decohesion crack. The effects of the line width have also been addressed. The results show that for two-layer films the energy release rate for steady-state decohesion cracks decreases dramatically as B/h decreases, in the range B/h<40, where B is the line width and h is the thickness of the superlayer. For narrow lines the plane strain solutions overestimate the energy release rate. The numerical results are consistent with the experimental observations on lines with different width.
