Abstract
OBJECTIVE In transcranial MR-guided focused ultrasound (TcMRgFUS), fiber tractography using diffusion tensor imaging (DTI) has been proposed as a direct method to identify the ventral intermediate nucleus (Vim), the ventral caudal nucleus (Vc), and the pyramidal tract (PT). However, the limitations of the DTI algorithm affect the accuracy of visualizing anatomical structures due to its low-quality fiber tractography, whereas the application of the generalized q-sampling imaging (GQI) algorithm enables the visualization of high-quality fiber tracts, offering detailed insights into the spatial distribution of motor cortex fibers. This retrospective study aimed to investigate the usefulness of high-precision fiber tractography using the GQI algorithm as a planning image in TcMRgFUS to achieve favorable clinical outcomes. METHODS This study included 20 patients who underwent TcMRgFUS. The Clinical Rating Scale for Tremor (CRST) scores and MR images were evaluated pretreatment and at 24 hours and 3-6 months after treatment. Cases were classified based on the presence and adversity of adverse events (AEs): no AEs, mild AEs without additional treatment, and severe AEs requiring prolonged hospitalization. Fiber tractography of the Vim, Vc, and PT was visualized using the DTI and GQI algorithm. The overlapping volume between Vim fibers and the lesion was measured, and correlation analysis was performed. The relationship between AEs and the overlapping volume of the Vc and PT fibers within the lesions was examined. The cutoff value to achieve a favorable clinical outcome and avoid AEs was determined using receiver operating characteristic curve analysis. RESULTS All patients showed improvement in tremors 24 hours after treatment, with 3 patients experiencing mild AEs and 1 patient experiencing severe AEs. At the 3- to 6-month follow-up, 5 patients experienced recurrence, and 2 patients had persistent mild AEs. Although fiber visualization in the motor cortex using the DTI algorithm was insufficient, the GQI algorithm enabled the visualization of significantly higher-quality fibers. A strong correlation was observed between the overlapping volume that intersects the lesion and Vim fibers and the degree of tremor improvement (r = 0.72). Higher overlapping volumes of Vc and PT within the lesion were associated with an increased likelihood of AEs (p < 0.05); the cutoff volume of Vim fibers within the lesion for a favorable clinical outcome was 401 mm3, while the volume of Vc and PT within the lesion to avoid AEs was 99 mm3. CONCLUSIONS This pilot study suggests that incorporating the high-precision GQI algorithm for fiber tractography as a planning imaging technique for TcMRgFUS has the potential to enhance targeting precision and achieve favorable clinical outcomes.

Abstract
Hematopoietic stem cell transplantation (HSCT) is only indicated for acute lymphoblastic leukemia (ALL) patients for whom other treatments are unlikely to be curative. However, outcomes of patients not in complete remission (CR) at HSCT remain very poor. To improve the outcomes of patients receiving HSCT, it is important to obtain detailed clinical information about patients with ALL receiving HSCT in CR and not in CR. Patients enrolled in the Japan Association of Childhood Leukemia Study ALL-02 who underwent HSCT and were not in CR (non-CR patients, n = 55) were examined. The 1-year overall survival (OS) rate of non-CR patients was 27.3%. Compared with CR patients, non-CR patients experienced very early and early relapse significantly more frequently and had poorer prognostic factors. Most interestingly, high hyperdiploid (HHD) patients showed an excellent 1-year OS of 80%. In addition, long-term survival among surviving HHD patients was longer than 5 years. All eight patients who survived after undergoing HSCT while not in CR were younger than 10 years at initial diagnosis and were negative for central nervous system involvement. While limited, these results suggest that a subset of patients may benefit from HSCT while not in CR.

Abstract
In Asia, a few countries have a long and established history of collaborative clinical trials successfully formed national children's cancer study groups, but many still do not have such groups. The process of forming national children's cancer groups is fraught with many hurdles, which varies among the countries. One of the basic requirements for running clinical trials is an affordable health care system in which most of the children with cancer can receive the proposed treatment. The health insurance coverage for children with cancer varies from <20% to as high as 100% among Asian countries, and the operation of clinical trials must also be adjusted accordingly. Shortage of research personnel is common, including medical, nursing, research coordinators, and data managers. The establishment of the Asian Pediatric Hematology and Oncology Group aims to provide a good platform for promotion of international clinical trials in the Asian countries.

Abstract
INTRODUCTION Transcranial magnetic resonance-guided focused ultrasound surgery (TcMRgFUS) has the advantage of allowing immediate evaluation of therapeutic effects after each sonication and intraoperative magnetic resonance imaging (MRI) to visualize the lesion. When the image shows that the lesion has missed the planned target and the therapeutic effects are insufficient, the target of the subsequent ablation can be finely adjusted based on the image. The precision of this adjustment is determined by the image quality. However, the current intraoperative image quality with a 3.0T MRI system is insufficient for precisely detecting the lesion. Thus, we developed and validated a method for improving intraoperative image quality. METHODS Because intraoperative image quality is affected by transmitter gain (TG), we acquired T2-weighted images (T2WIs) with two types of TG: the automatically adjusted TG (auto TG) and the manually adjusted TG (manual TG). To evaluate the character of images with 2 TGs, the actual flip angle (FA), the image uniformity, and the signal-to-noise ratio (SNR) were measured using a phantom. Then, to assess the quality of intraoperative images, T2WIs with both TGs were acquired during TcMRgFUS for 5 patients. The contrast-to-noise ratio (CNR) of the lesion was retrospectively estimated. RESULTS The images of the phantom with the auto TG showed substantial variations between the preset and actual FAs (p < 0.01), whereas on the images with the manual TG, there were no variations between the two FAs (p > 0.05). The total image uniformity was considerably lower with the manual TG than with the auto TG (p < 0.01), indicating that the image's signal values with the manual TG were more uniform. The manual TG produced significantly higher SNRs than the auto TG (p < 0.01). In the clinical study, the lesions were clearly detected in intraoperative images with the manual TG, but they were difficult to identify in images with the auto TG. The CNR of lesions in images with manual TG was considerably higher than in images with auto TG (p < 0.01). CONCLUSION Regarding intraoperative T2WIs using a 3.0T MRI system during TcMRgFUS, the manual TG method improved image quality and delineated the ablative lesion more clearly than the current method with auto TG.

Abstract
In Japan, clinical genetic services became available in the 1970s, and genomic medicine, including genetic counseling (GC), developed rapidly. However, research on the outcomes of GC in Japan is limited. Japan has a unique cultural context, and appropriate GC methods have not yet been optimized for this population. The current study aimed to evaluate the psychological status of Japanese patients and their companions undergoing GC and the outcomes of GC. We used the Quality of Care Through the Patients' Eyes-gene cancer (QUOTE-geneCA ), the Genetic Counseling Outcome Scale-24 (GCOS-24), and the State-Trait Anxiety Inventory (STAI) to evaluate patients and their companions' needs and preferences regarding GC, empowerment, and anxiety, respectively. We evaluated stress status during GC by measuring saliva cortisol levels. QUOTE-geneCA results for patients (n = 69) and a group of patients and their companions (n = 96) revealed that participants felt that it was important that skilled medical staff explained medical information and provided advice in an easily understandable manner. Japanese patients and their companions regarded the procedural aspects of counseling as most important and their autonomy in decision-making as less important. GCOS-24 results revealed a significant increase in empowerment scores in 38 patients (by 9.63 points) from pre- to post-GC (p < 0.001; Cohen's d = 0.79). STAI results revealed a significant decrease in state anxiety for patients (6.11 points; p < 0.001; Cohen's d = 0.66). Cortisol levels in patients significantly decreased after GC (p = 0.001). The improvement of empowerment scores from pre- to post-GC among patients and their companions were significantly negatively correlated with pre-GC empowerment scores (p < 0.001), trait anxiety scores (p = 0.001), and the number of people living together (p = 0.011). The change of cortisol levels during GC in patients and their companions was significantly positively correlated with trait anxiety score (p = 0.027). This study suggested that these characteristics of Japanese patients and their companions may predict GC outcomes.

Abstract
OBJECTIVES This study aimed to assess the perception of PBL among Japanese medical students. METHODS Learning effects and challenges of PBL from the students' viewpoint were assessed with an exploratory sequential mixed method. Focus group discussions followed by thematic analysis were conducted with 27 students and residents. Then a questionnaire survey was carried out. A total of 119 out of 258 students (46.1%) responded. The results from 24 questions were analyzed with a residual analysis. RESULTS Thematic analysis extracted 14 themes from four discussion topics. The participants in focus group discussion regarded the PBL program as a better learning method than lectures. But some key phrases on the challenge of social interaction, including reluctance to actively discuss and collaborate with unfamiliar peers, were found. The questionnaire survey revealed a significantly lower adjusted standardized residual (ASR) for the positive response in five of six questions in the category of social interaction; improvement of communication skills (ASR = -3.303, n = 118, p < .001), enhancement of responsibility at group discussions (ASR = -2.078, n = 119, p = .038), building social networking (ASR = -3.006, n = 119, p = .003), becoming to sympathize with patients (ASR = -2.449, n = 119, p = .014) and understanding social aspects of clinical practice (ASR = -5.790, n = 119, p < .001). Conclusion: The Japanese medical students perceived PBL as an effective learning strategy. However, they had a problem with social interactions.

Abstract
In recent years, gadolinium ethoxybenzyl diethylenetriamine pantaacetic acid (Gd-EOB-DTPA) has been commonly used in magnetic resonance imaging (MRI) for liver contrast studies. The purpose of this study was to investigate the effect of Hyper SENSE factor on contrast in the Gd-EOB-DTPA hepatocyte phase. The subjects were 21 patients [16 males and 5 females, aged 50-94 years (mean age 68±12years)] who underwent hepatic contrast-enhanced MRI with Gd-EOB-DTPA from March 2021 to December 2021. The contrast ratios (CRs) of liver/spleen and liver/tumor were measured when the Hyper SENSE factor was changed to 1.0, 1.4 and 1.8. As a result, there was no statistically significant difference in signal intensity and CR with the change in the Hyper SENSE factor. In this study, the acquisition time can be shortened without decreasing the CR; therefore, it was suggested to improve MR images to avoid motion artifact.

Abstract
Among western African countries, the Republic of Ghana has maintained an economic growth rate of 5% since the 1980s and is now categorized as a middle-income country. However, as with other developing countries, Ghana still has challenges in the effective implementation of surveillance for infectious diseases. Facing public health emergencies of international concern (PHEIC), it is crucial to establish a reliable sample transportation system to the referral laboratory. Previously, surveillance capacity in Ghana was limited based on Integrated Disease Surveillance and Response, and therefore the "Surveillance and Laboratory Support for Emerging Pathogens of Public Health Importance in Ghana (SLEP)" was introduced to strengthen diarrhea surveillance. The SLEP project started with a sentinel diarrhea survey supported by SATREPS/JICA in collaboration with National Public Health Reference Laboratory (NHPRL) and Noguchi Memorial Institute of Medicine (NMIMR). The base-line survey revealed the limited capacity to detect diarrhea pathogens and to transfer samples from health centers to NHPRL. The involvement of private clinic/hospital facilities into the surveillance network is also crucial to strengthen surveillance in Ghana. The strong and interactive relationship between the two top referral laboratories, NHPRL under the Ministry of Health NMIMR and under the Ministry of Education, enables Ghana Health Services and is critical for the rapid response against PHEIC. In future, we hope that the outcome of the SLEP surveillance project could contribute to building a surveillance network with more timely investigation and transfer of samples to referral labs.

Abstract
MOTIVATION Cell-cell communications regulate internal cellular states, e.g. gene expression and cell functions, and play pivotal roles in normal development and disease states. Furthermore, single-cell RNA sequencing methods have revealed cell-to-cell expression variability of highly variable genes (HVGs), which is also crucial. Nevertheless, the regulation of cell-to-cell expression variability of HVGs via cell-cell communications is still largely unexplored. The recent advent of spatial transcriptome methods has linked gene expression profiles to the spatial context of single cells, which has provided opportunities to reveal those regulations. The existing computational methods extract genes with expression levels influenced by neighboring cell types. However, limitations remain in the quantitativeness and interpretability: they neither focus on HVGs nor consider the effects of multiple neighboring cell types. RESULTS Here, we propose CCPLS (Cell-Cell communications analysis by Partial Least Square regression modeling), which is a statistical framework for identifying cell-cell communications as the effects of multiple neighboring cell types on cell-to-cell expression variability of HVGs, based on the spatial transcriptome data. For each cell type, CCPLS performs PLS regression modeling and reports coefficients as the quantitative index of the cell-cell communications. Evaluation using simulated data showed our method accurately estimated the effects of multiple neighboring cell types on HVGs. Furthermore, applications to the two real datasets demonstrate that CCPLS can extract biologically interpretable insights from the inferred cell-cell communications. AVAILABILITY AND IMPLEMENTATION The R package is available at https://github.com/bioinfo-tsukuba/CCPLS. The data are available at https://github.com/bioinfo-tsukuba/CCPLS_paper.

Abstract
A new pulse UV irradiation-induced chemiluminescence (CL) determination method was developed for l-tyrosine using the luminol derivative L-012. The proposed method depends on the formation of reactive oxygen species (ROS) upon pulse UV irradiation of l-tyrosine; then, these ROS react with L-012 producing strong CL. The proposed method showed excellent sensitivity and ultraselectivity toward l-tyrosine. The mechanism of the developed CL method was studied using ROS scavengers, HPLC, and mass spectrometry. The method was linear for l-tyrosine in the range of 0.03-50 μM. Minor changes in the l-tyrosine structure, including hydroxylation, dehydroxylation, phosphorylation, or decarboxylation, were found to lead to a strong decrease in CL. Using the excellent selectivity of the proposed method for l-tyrosine, we have developed a CL assay for measuring alkaline phosphatase activity in the range of 0.02-15 U/L with the limit of detection (LOD) of 4 mU/L using the nonchemiluminescent O-phospho-l-tyrosine as a substrate. Furthermore, the CL reaction was applied for tyrosinase activity assay as this enzyme can convert l-tyrosine to the nonchemiluminescent l-dopa. The decrease in CL is correlated with the tyrosinase activity in the range of 0.025-0.75 U/mL with an LOD of 1.5 mU/mL. Moreover, the tyrosinase activity assay was successfully applied for the determination of IC50 of the tyrosinase inhibitors kojic acid and benzoic acid. Therefore, our novel pulse UV irradiation CL method for the determination of l-tyrosine was not only suitable for the determination of this vital amino acid but also extended to the successful determination of its producing and metabolizing enzymes and their inhibitors.

Abstract
So far, no studies investigated the association between pharmacist intervention and rehabilitation outcomes. The aim of study was to establish whether the pharmacist-led deprescribing intervention affects rehabilitation outcomes. This retrospective, observational, single-center, cohort study included consecutive geriatric patients (n = 448) with pharmacist-led intervention between 2017 and 2019. Participants were divided based on pharmacist-led deprescribing and non deprescribing interventions during hospitalization. Demographic data, laboratory data, the Functional Independence Measure were (FIM) analyzed between the groups. Multiple linear regression analysis was performed to analyze the relationship between pharmacist-led deprescribing and FIM total gain. The primary outcome was FIM total gain. The rate of pharmacist intervention during the study period was 92.4%. A multiple linear regression analysis of FMI-T gain, adjusting for confounding factors, revealed that the pharmacist-led deprescribing intervention was independently correlated with FMI-T gain. Particularly, the use of dyslipidemia drugs, antipsychotic drugs, hypnotics, and nonsteroidal anti-inflammatory drugs significantly decreased during hospitalization. The pharmacist-led deprescribing intervention was independently and significantly associated with FIM-T gain. The pharmacist-led deprescribing intervention improved functional recovery in a rehabilitation setting.

Abstract
OBJECTIVE Sufficient thermal increase capable of generating thermocoagulation is indispensable for an effective clinical outcome in patients undergoing magnetic resonance-guided focused ultrasound (MRgFUS). The skull density ratio (SDR) is one of the most dominant predictors of thermal increase prior to treatment. However, users currently rely only on the average SDR value (SDRmean) as a screening criterion, although some patients with low SDRmean values can achieve sufficient thermal increase. The present study aimed to examine the numerical distribution of SDR values across 1024 elements to identify more precise predictors of thermal increase during MRgFUS. METHODS The authors retrospectively analyzed the correlations between the skull parameters and the maximum temperature achieved during unilateral ventral intermediate nucleus thalamotomy with MRgFUS in a cohort of 55 patients. In addition, the numerical distribution of SDR values was quantified across 1024 elements by using the skewness, kurtosis, entropy, and uniformity of the SDR histogram. Next, the authors evaluated the correlation between the aforementioned indices and a peak temperature > 55°C by using univariate and multivariate logistic regression analyses. Receiver operating characteristic curve analysis was performed to compare the predictive ability of the indices. The diagnostic performance of significant factors was also assessed. RESULTS The SDR skewness (SDRskewness) was identified as a significant predictor of thermal increase in the univariate and multivariate logistic regression analyses (p < 0.001, p = 0.013). Moreover, the receiver operating characteristic curve analysis indicated that the SDRskewness exhibited a better predictive ability than the SDRmean, with area under the curve values of 0.847 and 0.784, respectively. CONCLUSIONS The SDRskewness is a more accurate predictor of thermal increase than the conventional SDRmean. The authors suggest setting the SDRskewness cutoff value to 0.68. SDRskewness may allow for the inclusion of treatable patients with essential tremor who would have been screened out based on the SDRmean exclusion criterion.

Abstract
Acute lymphoblastic leukemia (ALL) is the most common childhood cancer. As overall cure rates of childhood ALL have improved, reduction of overall treatment intensity while still ensuring excellent outcomes is imperative for low-risk patients. We report the outcomes of patients treated following the standard-risk protocol from the prospective Japan Association of Childhood Leukemia Study (JACLS) ALL-02 study, which was conducted between 2002 and 2008 for patients with newly diagnosed ALL aged 1-18 years. Of 1138 patients with B-cell precursor ALL, 388 (34.1%) were allocated to this protocol. Excellent outcomes were achieved despite the overall treatment intensity being lower than that of most contemporary protocols: 4 years event-free survival (EFS) was 92.3% and 4 years overall survival 98.2%. Patients with high hyperdiploidy (HHD) involving triple trisomy (trisomy of chromosomes 4, 10, and 17) or ETV6-RUNX1 had even better outcomes (4 years EFS 97.6% and 100%, respectively). Unique characteristics of this protocol include a selection of low-risk patients with a low initial WBC count and good early treatment response and reduction of cumulative doses of chemotherapeutic agents while maintaining dose density. In Japan, we are currently investigating the feasibility of this protocol while incorporating minimal residual disease into the patient stratification strategy.

Abstract
A 77-year-old woman presented with systemic lymphadenopathy and bilateral pleural effusion. Angioimmunoblastic T-cell lymphoma (AITL) was diagnosed based on the results of a lymph node biopsy. AITL cells expressed the aberrant antigen of CD56. The bilateral pleural effusion was attributed to chylothorax, not the infiltration of lymphoma cells into the pleura, as determined by the pleural fluid analysis. We therefore diagnosed her with CD56-positive AITL complicated by chylothorax. She achieved complete remission by multidrug chemotherapy. AITL is commonly complicated by pleural effusion, but rarely by chylothorax. This is the first case of CD56-positive AITL complicated by chylothorax.

Abstract
BACKGROUND To develop the skills needed in health care teams, training communication and teamwork skills are important in medical education. Small group collaborative learning is one of the methods utilized in such trainings, and peer evaluation is suggested to be useful in reinforcing the effectiveness of group learning activities. In Mie University Faculty of Medicine, group work consisting of book review sessions of liberal arts education in the first grade and problem-based learning (PBL) sessions in preclinical years were conducted using the same peer evaluation system that included three domains: degree of prior learning, contribution to group discussion, and cooperative attitude. This study was conducted to determine the relationships among behaviors during group work and the academic achievement of medical students. METHODS With the data from a cohort of medical students in three consecutive academic years (n = 340), peer evaluation scores in groupworks of book review sessions, those in PBL sessions and paper test scores of preclinical years were analyzed. The correlations were analyzed with Spearman's correlation coefficient, and the respective scores were compared by using the Wilcoxon signed-ranked test. RESULTS Significant correlations were observed among the evaluation scores of respective domains in group work and paper test scores. The degree of prior learning had the strongest relationship among the three domains (rs = 0.355, p < 0.001 between book review sessions and PBL; rs = 0.338, p < 0.001 between book review sessions and paper test score; rs = 0.551, p < 0.001 between PBL and paper test score). Peer evaluation scores of respective domains were found to be significantly higher in PBL. CONCLUSION Medical students maintained their groupwork behaviors to some extent from early school to preclinical years. Those behaviors were positively related to their academic achievement in the later years of the medical education curriculum. Our study highlighted the importance of the early introduction of group work. The results will be useful to motivate medical students to put more effort into group work.

Abstract
BACKGROUND Social awareness of cancer can be changed with cancer education and proper distribution of cancer information. This study addressed the current situation and historical changes to children's perception of cancer. METHODS Questionnaire surveys were conducted among healthy school children aged 10-15 years in 2008 and 2018. Knowledge of cancer was surveyed and compared with that of asthma, tuberculosis, and measles. The children were asked about their health information resources. RESULTS The numbers of participants and collection rates were 438 and 63.9% in 2008, and 320 and 44.7% in 2018. Children's perception of cancer changed significantly in the last decade. The proportion of respondents answering "cancer affects children" changed from 78.3 to 89.5% (P = 0.0001), "cancer is preventable" from 42.0 to 49.7% (P = 0.0425), and "cancer is curable," from 52.4 to 66.0% (P = 0.0003). Significantly more junior high school students answered that cancer is preventable than elementary school children in 2018 (55.9 vs 42.7%, P = 0.0028). The major resources of information on health were television, parents, and books. The proportion of children choosing the Internet significantly increased from 15.3 to 47.8% (P < 0.0001). Significantly more junior high school students selected television and the Internet than elementary school children (94.5 vs 86.9%, P = 0.0202 for television; 57.1 vs 37.9%, P = 0.0007 for the Internet). CONCLUSIONS The proportion of children correctly perceiving cancer information had increased in the last decade. Junior high school students better understood the information. The Internet is of increasing importance as an information resource for school children.

Abstract
BACKGROUND The quality of end-of-life (Q-EOL) care is influenced by various factors such as resources for palliative care (PC). We introduced a multi-professional expert team (MET) in 2014, which provides home-based care for children and adolescents with incurable cancer. This study investigated the impacts of the outreach activities by the MET on Q-EOL care of pediatric oncology patients. METHODS This observational study retrospectively examined 112 patients receiving end-of-life care between 1989 and 2018 at a pediatric cancer center in Japan. Some of the indicators of Q-EOL care before and after the introduction of the outreach activities by the MET were compared. The subjects were 92 in pre-MET and 20 in post-MET periods. RESULTS The median number of days for which the patients stayed at home during the final seven or 30 days were significantly prolonged in the post-MET period (0.0 vs 1.5 days, P = 0.020, 3.0 vs 12.0 days, P = 0.042). The change was more significant in hematologic malignancies than solid and central nervous system tumors. Patients receiving longer PC before their deaths could stay at home longer during the last 7 days. The ratio of patients receiving PC for more than 2 months was significantly increased in post-MET period (60.9 vs 90.0%, P = 0.014). More patients also greeted their deaths at home in the post-MET period (3.3 vs 25.0%, P < 0.001). CONCLUSIONS The activities of the MET transformed the end-of-life care of children and adolescents with incurable cancer. Earlier transitions to PC from curative treatment were associated with longer home-based care and more deaths at home.

Abstract
BACKGROUND The practice of cancer diagnosis disclosure to children has been changed with the times. The regulations of clinical trials in the 2000s might change the practice in Japan. However, the perspective of this topic among children and adults has not been investigated in detail. METHODS We studied changes in the practice of information sharing with children with cancer at pediatric cancer centers and the perspective of cancer diagnosis disclosure to children among school children, their parents and pediatric oncologists in the last 20 years by comparing the results of questionnaire surveys conducted in 1998, 2008 and 2018. RESULTS This study revealed that the performing rate has increased with the times, but the institutions actively performing for children aged 7-9 years were 36.4% even in the 2018 survey. More than 70% of children wished diagnosis disclosure if they suffer from cancer in the series of surveys, while the ratio of parents who tell cancer diagnosis to their children hovered at 34.5 to 53.7% (p < 0.001 in all surveys). The ratio of pediatric oncologists having the policy to perform diagnosis disclosure proactively increased from 9.3 to 60.0%, while that of parents having the same policy stayed at 5.3% even in 2018. CONCLUSIONS The performing rate of information sharing with children with cancer was significantly changed in the last 20 years. The opinion gaps were observed between parents and children and between parents and pediatric oncologists.

Abstract
Acute gastroenteritis associated with diarrhea is considered a serious disease in Africa and South Asia. In this study, we examined the trends in the causative pathogens of diarrhea and the corresponding gut microbiota in Ghana using microbiome analysis performed on diarrheic stools via 16S rRNA sequencing. In total, 80 patients with diarrhea and 34 healthy adults as controls, from 2017 to 2018, were enrolled in the study. Among the patients with diarrhea, 39 were norovirus-positive and 18 were rotavirus-positive. The analysis of species richness (Chao1) was lower in patients with diarrhea than that in controls. Beta-diversity analysis revealed significant differences between the two groups. Several diarrhea-related pathogens (e.g., Escherichia-Shigella, Klebsiella and Campylobacter) were detected in patients with diarrhea. Furthermore, co-infection with these pathogens and enteroviruses (e.g., norovirus and rotavirus) was observed in several cases. Levels of both Erysipelotrichaceae and Staphylococcaceae family markedly differed between norovirus-positive and -negative diarrheic stools, and the 10 predicted metabolic pathways, including the carbohydrate metabolism pathway, showed significant differences between rotavirus-positive patients with diarrhea and controls. This comparative study of diarrheal pathogens in Ghana revealed specific trends in the gut microbiota signature associated with diarrhea and that pathogen-dependent dysbiosis occurred in viral gastroenteritis.

Abstract
Background The efficacy of magnetic resonance‐guided focused ultrasound (MRgFUS) thalamotomy for the treatment of focal hand dystonia (FHD) is not well known. Objective We aimed to prospectively investigate the efficacy of MRgFUS thalamotomy for the treatment of FHD. Methods We performed MRgFUS thalamotomy of the ventro‐oral (Vo) nucleus in 10 patients with FHD. We evaluated the scores of the Writer's Cramp Rating Scale (WCRS, 0–30; higher scores indicating greater severity), Tubiana Musician's Dystonia Scale (TMDS, 0–5; lower scores indicating greater severity), and Arm Dystonia Disability Scale (ADDS, 0%–100%; lower scores indicating greater disability) at baseline and 3 and 12 months post‐treatment. Results WCRS, TMDS, and ADDS scores significantly improved from 6.3 ± 2.7, 1.4 ± 0.5, and 58.7% ± 14.3% at baseline to 1.6 ± 3.1 (P = 0.011), 5.0 ± 0 (P = 0.0001), and 81.6% ± 22.9% (P = 0.0229) at 12 months, respectively. There was one prolonged case of dysarthria at 12 months. Conclusion We show that MRgFUS Vo‐thalamotomy significantly improved FHD. © 2021 The Authors.

Abstract
BACKGROUND Several feasibility studies and a randomized, controlled, multicenter trial have demonstrated the safety and efficacy of unilateral transcranial magnetic resonance-guided focused ultrasound (FUS) lesioning of the ventral intermediate thalamic nucleus in treating essential tremor. OBJECTIVE To evaluate the safety and efficacy of FUS thalamotomy in a Japanese patient cohort through a prospective, multicenter, single-arm confirmatory trial. METHODS A total of 35 patients with disabling refractory essential tremor underwent unilateral FUS thalamotomy and were followed up for 12 post-treatment months. Safety was measured as the incidence and severity of treatment-related adverse events. Efficacy was measured as the tremor severity and quality of life improvements using the Clinical Rating Scale for Tremor and Questionnaire for Essential Tremor. RESULTS The mean skull density ratio (SDR) was 0.47. There was a significant decrease in the mean postural tremor score of the treated hand from baseline to 12 mo by 56.4% (95% CI: 46.7%-66.1%; P < .001), which was maintained at last follow-up. Quality of life improved by 46.3% (mean overall Questionnaire for Essential Tremor score of 17.4 [95% CI: 12.1-22.7]) and there were no severe adverse events. The most frequent adverse event was gait disturbance and all events resolved. CONCLUSION Unilateral FUS thalamotomy allowed significant and sustained tremor relief and improved the quality of life with an outstanding safety profile. The observed safety and efficacy of FUS thalamotomy were comparable to those reported in a previous multicenter study with a low SDR, and inclusion of the low SDR group did not affect effectiveness.

Abstract
OBJECTIVE In transcranial magnetic resonance imaging-guided focused ultrasound (TcMRgFUS), a high skull density ratio (SDR) is advantageous to achieve a sufficiently high temperature at the target. However, it is not easy to estimate the temperature rise because the SDR shows different values depending on the reconstruction filter used. The resolution characteristic of a computed tomography (CT) image depends on a modulation transfer function (MTF) defined by the reconstruction filter. Differences in MTF induce unstable SDRs. The purpose of this study was both to standardize SDR by developing a method to correct the MTF and to enable effective patient screening prior to TcMRgFUS treatment and more accurate predictions of focal temperature. METHODS CT images of a skull phantom and five subjects were obtained using eight different reconstruction filters. A frequency filter (FF) was calculated using the MTF of each reconstruction filter, and the validity of SDR standardization was evaluated by comparing the variation in SDR before and after FF correction. Subsequently, FF processing was similarly performed using the CT images of 18 patients who had undergone TcMRgFUS, and statistical analyses were performed comparing the relationship between the SDRs before and after correction and the maximum temperature in the target during TcMRgFUS treatment. RESULTS The FF was calculated for each reconstruction filter based on one manufacturer's BONE filter. In the CT images of the skull phantom, the SDR before FF correction with five of the other seven reconstruction filters was significantly smaller than that with the BONE filter (p < 0.01). After FF correction, however, a significant difference was recognized under only one condition. In the CT images of the five subjects, variation of the SDR due to imaging conditions was significantly improved after the FF correction. In 18 cases treated with TcMRgFUS, there was no correlation between SDR before FF correction and maximum temperature (rs = 0.31, p > 0.05); however, a strong positive correlation was observed after FF correction (rs = 0.71, p < 0.01). CONCLUSIONS After FF correction, the difference in SDR due to the reconstruction filter used is smaller, and the correlation with temperature is stronger. Therefore, the SDR can be standardized by applying the FF, and the maximum temperature during treatment may be predicted more accurately.

Abstract
Purpose ImmunoCAP® (ImmunoCAP) and IMMULITE® 2000 3gAllergy™ (3gAllergy) systems are major quantitative allergen-specific immunoglobulin E (sIgE) assay methods. Due to the heterogeneous nature of allergenic extracts and differences in the assay format, quantitation of allergen-sIgEs is not expected to correlate well between different methods. However, we have recently reported good agreement between the methods in the diagnosis of egg allergy. This study aimed to determine and correlate the predictive values of sIgE by the two systems in the diagnosis of milk and wheat allergies. Methods Children who had undergone oral food challenge (OFC) for the diagnosis of milk and wheat allergies were enrolled. The OFCs were performed to diagnose either true allergy in the 1-year-old group (A) or tolerance in the 2- to 6-year-old group (B). Milk, casein and β-lactoglobulin, and wheat and ω-5 gliadin sIgE values were measured using the 2 systems. The predictive accuracy of each sIgE for the OFC outcome was assessed using receiver operating characteristic (ROC) curves. The probability of a positive OFC outcome was estimated by logistic regression analysis. Results A total of 395 patients were recruited from 7 primary care clinics and 19 hospitals in Japan. Milk and wheat OFCs were performed for 87 and 102 group A patients, and 124 and 82 group B patients, respectively. ROC analysis yielded similar areas under the curve for the 2 assays (0.7–0.9). The log-transformed sIgE data showed a strong linear correlation with the estimated probabilities (R > 0.9). Conclusions The 2 systems may be interchangeable for diagnosis of milk and wheat allergies in young children.

Abstract
We report the case of a patient with hypothalamic hamartoma (HH) who was successfully treated with magnetic resonance-guided focused ultrasound (MRgFUS) for ablation as a disconnection surgery. A 26-year-old man with gelastic epilepsy had been diagnosed with HH at 3 years of age, and antiepileptic drugs were administered due to worsening episodes. Magnetic resonance imaging showed a sessile parahypothalamic hamartoma and MRgFUS ablation was performed, creating an oval-shaped lesion at the boundary area of the HH. Dramatic improvements in seizure symptoms were noted, and he was seizure-free on decreased antiepileptic drugs without any adverse events over the 1-year follow-up period.

Abstract
Minimal residual disease of leukemia may reside in the bone marrow (BM) microenvironment and escape the effects of chemotherapeutic agents. This study investigated interactions between B cell precursor (BCP)-acute lymphoblastic leukemia (ALL) cells and BM mesenchymal stromal cells (BM-MSCs) in vitro. Five BCP-ALL cell lines established from pediatric patients and primary samples from a BCP-ALL patient were examined by flow cytometry and immunocytochemistry for expression of specific cell surface markers and cell adhesion proteins. The cell lines developed chemoresistance to commonly used anti-leukemic agents through adhesion to MSC-TERT cells in long-term culture. The change in chemosensitivity after adhering to BM-MSCs was associated with the expression of CD34, CD133, P-glycoprotein and BCRP/ABCG2, and downregulation of CD38. Similar phenotypic changes were observed in primary samples obtained by marrow aspiration or biopsy from a BCP-ALL patient. BM-MSC-adhering leukemia cells also showed deceleration of cell proliferation and expressed proteins in the Cadherin and Integrin pathways. These results suggest that BCP-ALL cells residing in the BM microenvironment may acquire chemoresistance by altering their phenotype to resemble that of cancer stem cells. Our results indicate that cell adhesion could be potentially targeted to improve the chemosensitivity of residual BCP-ALL cells in the BM microenvironment.

Abstract
BACKGROUND We report the first case of transcranial magnetic resonance-guided focused ultrasound (MRgFUS) for mesial temporal lobe epilepsy (MTLE). CASE PRESENTATION The target was located 20 mm lateral from the midline and 15 mm above the skull base (left hippocampus). Despite the application of maximal energy, the ablation temperature did not exceed 50 °C, probably because of the low number of effective transducer elements with incident angles below 25 degrees. The skull density ratio was 0.56. Post-operative magnetic resonance imaging did not reveal any lesion and the patient remained almost seizure-free for up to 12 months. CONCLUSIONS This preliminary case report suggests that MRgFUS may be effective for treating cases of MTLE. Therefore, the safety and feasibility of MRgFUS should be evaluated in future studies with larger numbers of participants and longer follow-up duration.

Abstract
OBJECTIVE This study evaluated changes of fractional anisotropy (FA) in the ventral intermediate nucleus (VIM) of the thalamus after transcranial MR-guided focused ultrasound (TcMRgFUS) thalamotomy and their associations with clinical outcome. METHODS Clinical and radiological data of 12 patients with medically refractory essential tremor (mean age 76.5 years) who underwent TcMRgFUS thalamotomy with VIM targeting were analyzed retrospectively. The Clinical Rating Scale for Tremor (CRST) score was calculated before and at 1 year after treatment. Measurements of the relative FA (rFA) values, defined as ratio of the FA value in the targeted VIM to the FA value in the contralateral VIM, were performed before thalamotomy, and 1 day and 1 year thereafter. RESULTS TcMRgFUS thalamotomy was well tolerated and no long-term complications were noted. At 1-year follow-up, 8 patients demonstrated relief of tremor (improvement group), whereas in 4 others persistent tremor was noted (recurrence group). In the entire cohort, mean rFA values in the targeted VIM before treatment, and at 1 day and 1 year after treatment, were 1.12 ± 0.15, 0.44 ± 0.13, and 0.82 ± 0.22, respectively (p < 0.001). rFA values were consistently higher in the recurrence group compared with the improvement group, and the difference reached statistical significance at 1 day (p < 0.05) and 1 year (p < 0.01) after treatment. There was a statistically significant (p < 0.01) positive correlation between rFA values in the targeted VIM at 1 day after thalamotomy and CRST score at 1 year after treatment. Receiver operating characteristic curve analysis revealed that the optimal cutoff value of rFA at 1 day after thalamotomy for prediction of symptomatic improvement at 1-year follow-up is 0.54. CONCLUSIONS TcMRgFUS thalamotomy results in significant decrease of rFA in the targeted VIM, at both 1 day and 1 year after treatment. Relative FA values at 1 day after treatment showed significant correlation with CRST score at 1-year follow-up. Therefore, FA may be considered a possible imaging biomarker for early prediction of clinical outcome after TcMRgFUS thalamotomy for essential tremor.

Abstract
AbstractPurposeSmoking rates in schizotypic individuals are shown to be elevated, as in patients with schizophrenia, although findings on the association of smoking with different symptomatology of schizotypy have been mixed. Moreover, possible moderating effects of schizotypy on the relationship between smoking and cognition have not been well documented.Subjects and methodsThe Schizotypal Personality Questionnaire (SPQ) and the full version of the Wechsler Memory Scale-Revised (WMS-R) were administered to 501 healthy adults. Subjects were divided into smokers (n = 85) and non-smokers (n = 416) based on the presence/absence of current smoking.ResultsThe analysis of covariance (ANCOVA) on the three factor scores as well as the total score of the SPQ, controlling for age and gender, revealed that cognitive-perceptual factor was significantly associated with an increased rate of smoking (P = 0.048). The ANCOVA on the WMS-R indices, with smoking group as a fixed factor and age, gender and total SPQ score as covariates, revealed that the schizotypy-by-smoking interaction was significant for attention/working memory (P = 0.029).Discussion and conclusionPositive schizotypy may be associated with more smoking. Schizotypy and smoking could interact with each other to negatively affect attention/working memory.

Abstract
This study was a second multicenter trial on childhood ALL by the Japan Childhood Leukemia Study Group (JACLS) to improve outcomes in non-T ALL. Between April 2002 and March 2008, 1138 children with non-T ALL were enrolled in the JACLS ALL-02 trial. Patients were stratified into three groups using age, white blood cell count, unfavorable genetic abnormalities, and treatment response: standard risk (SR), high risk (HR), and extremely high risk (ER). Prophylactic cranial radiation therapy (PCRT) was abolished except for CNS leukemia. Four-year event-free survival (4yr-EFS) and 4-year overall survival (4yr-OS) rates for all patients were 85.4% ± 1.1% and 91.2% ± 0.9%, respectively. Risk-adjusted therapy resulted in 4yr-EFS rates of 90.4% ± 1.4% for SR, 84.9% ± 1.6% for HR, and 66.5% ± 4.0% for ER. Based on NCI risk classification, 4yr-EFS rates were 88.2% in NCI-SR and 76.4% in NCI-HR patients, respectively. Compared to previous trial ALL-97, 4yr-EFS of NCI-SR patients was significantly improved (88.2% vs 81.2%, log rank p = 0.0004). The 4-year cumulative incidence of isolated (0.9%) and total (1.5%) CNS relapse were significantly lower than those reported previously. In conclusion, improved EFS in NCI-SR patients and abolish of PCRT was achieved in ALL-02.

Abstract
Musician's dystonia (MD) is a type of focal hand dystonia that develops only while playing musical instruments and interferes with skilled and fine movements. Lesioning of the ventro-oral (Vo) nucleus of the thalamus (Vo-thalamotomy) using radiofrequency can cause dramatic improvement in MD symptoms. Focused ultrasound (FUS) can make intracranial focal lesions without an incision. The authors used MRI-guided FUS (MRgFUS) to create a lesion on the Vo nucleus to treat a patient with MD. Tubiana's MD scale (TMDS) was used to evaluate the condition of musical play ranging from 1 to 5 (1: worst, 5: best). The patient was a 35-year-old right-handed man with involuntary flexion of the right second, third, and fourth fingers, which occurred while playing a classical guitar. Immediately after therapeutic sonications of FUS Vo-thalamotomy, there was dramatic improvement in the MD symptoms. The TMDS scores before; at 0 and 1 week after; and at 1, 3, 6, and 12 months after MRgFUS Vo-thalamotomy were 1, 4, 4, 5, 5, 5, and 5, respectively. No complications were observed. Focused ultrasound Vo-thalamotomy can be an effective treatment for MD.

Abstract
A preliminary interlaboratory study was conducted to evaluate the validity of the modified AOAC method for determination of total dietary fiber by Tada and Innami, in which the 3-step enzymatic digestion process in AOAC Method 991.43 is modified to a 2-step process without pH adjustment. Total dietary fiber contents in 8 representative foodstuffs were measured using both the original AOAC Method 991.43 and the modified method in 6 research facilities in Japan. Repeatability relative standard deviations, reproducibility relative standard deviations, and Horwitz ratio values from the modified method were equivalent to those from AOAC Method 991.43, except in the rice sample. However, this exceptional case shown in the modified method was entirely dissolved by the addition of α-amylase stabilizing agents. The modified method, which shortens the process of enzymatic digestion from 3 to 2 steps and in which only reaction temperature is adjusted under the same pH, was found not only to give accurate values comparable to the original method, but also to substantially reduce the labor required by the laboratory staff in the process of routine analysis. This study revealed that the validity of the modified method was further ensured by adding α-amylase stabilizing agents to the reaction system.

Abstract
Abstract
Purpose: Even though peritoneal metastasis (PM) in patients with gastric cancer (GC) has long been recognized to associate with poor survival, currently there is a lack of availability of biomarkers for its robust diagnosis. Availability of such biomarkers will facilitate more accurate identification of PM in GC patients, and could be clinically transformative as it will permit a timely intervention leading to reduced mortality associated with this malignancy. Recent advances in next generation sequencing technologies for an in-depth genomic and epigenomic profiling of various malignancies has paved the path for identification of previously unrecognized biomarkers. One such molecular substrates includes microRNAs (miRNAs), which are 18-25 nucleotides long, single-stranded noncoding RNAs, and act as post-transcriptional gene repressors. Although expression of specific miRNAs is frequently dysregulated in various human cancers including GC, their clinical significance as potential biomarkers for detecting PM has not been evaluated in large, adequately powered, independent patient cohorts. Accordingly, in this study, we undertook a comprehensive effort to identify and establish a novel miRNA-based signature for diagnosing presence of PM in GC patients.
Experimental design: We performed a genomewide, systematic biomarker discovery by analyzing miRNA expression profiles in primary tumors from GC patients with and without PM, followed by independent testing and validation in multiple patient cohorts of 354 patients, and establishment of a miRNA-signature for the diagnosis of PM in patients with advanced GC.
Results: Five miRNAs (miR-30a-5p, -134-5p, -337-3p, -659-3p, and -3917) were identified during the initial discovery phase; three of which (miR-30a-5p, -659-3p, and -3917) were significantly overexpressed in the primary tumors from PM-positive patients in the testing cohort (p=0.002, 0.04 and 0.007 respectively), and robustly distinguished patients with vs. without PM (AUC=0.82). Furthermore, high expression of these miRNAs was also associated with poor prognosis (HR=2.18, p=0.04). The efficacy of the combination miRNA-signature was successfully validated in an independent patient cohort (AUC=0.74). Finally, this miRNA signature in combination with the macroscopic Borrmann’s type score offered a significantly superior diagnostic accuracy in all three cohorts (AUC=0.87, 0.76, 0.79, respectively), and led to the establishment of a risk-prediction nomogram for the diagnosis of PM in GC patients.
Conclusions: Using a genomewide transcriptomic profiling biomarker discovery and validation approach, we have established a novel miRNA-signature that robustly identifies presence of peritoneal metastasis in gastric cancer patients, which might lead to improved survival outcomes in patients suffering from this malignancy.

Abstract
Background Secondary cancer is the most life-threatening late effect of childhood cancer. We investigated the clinical features of secondary bone/soft tissue sarcoma among childhood cancer survivors (CCSs). Methods We conducted a retrospective case-series study of 10 069 CCSs newly diagnosed with cancer between 1980 and 2009 across 15 Japanese hospitals. Twenty-one cases of pathologically diagnosed secondary bone/soft tissue sarcoma were selected, and the respective clinical courses were determined using additional questionnaires. Results The primary cancers included retinoblastoma (n = 7), acute lymphoblastic leukemia (n = 5), lymphoma (n = 5), osteosarcoma (n = 1), rhabdomyosarcoma (n = 1), brain tumor (n = 1) and Langerhans cell histiocytosis (n = 1). The median age at the primary cancer diagnosis was 2.9 years, and the male-to-female ratio was 16:5. The histological classifications of the secondary sarcoma included osteosarcoma (n = 10), malignant peripheral nerve sheath tumor (n = 4), rhabdomyosarcoma (n = 3), Ewing's sarcoma (n = 3) and primitive neuroectodermal tumor (n = 1). The median latency period to the secondary sarcoma was 10.2 years. Significant risk factors for secondary sarcoma in the multivariate Cox regression model included a history of retinoblastoma as the primary cancer (hazard ratio [HR], 20.9; 95% confidence interval [CI], 5.70-76.5) and autologous stem cell transplantation (SCT) (HR, 2.56; 95% CI, 1.08-6.03). Seventeen CCSs with secondary sarcoma underwent radiation, and nine, hematopoietic SCT. Twelve CCSs with secondary sarcoma achieved disease-free survival, while CCSs with hematological cancer or relapsed primary cancer who developed secondary sarcoma had the worst prognoses. Conclusion The prognoses of CCSs with secondary sarcoma may depend on the primary cancer or prior relapse of primary cancer.

Abstract
Mixed phenotype acute leukaemia (MPAL) is a high-risk subtype of leukaemia with myeloid and lymphoid features, limited genetic characterization, and a lack of consensus regarding appropriate therapy. Here we show that the two principal subtypes of MPAL, T/myeloid (T/M) and B/myeloid (B/M), are genetically distinct. Rearrangement of ZNF384 is common in B/M MPAL, and biallelic WT1 alterations are common in T/M MPAL, which shares genomic features with early T-cell precursor acute lymphoblastic leukaemia. We show that the intratumoral immunophenotypic heterogeneity characteristic of MPAL is independent of somatic genetic variation, that founding lesions arise in primitive haematopoietic progenitors, and that individual phenotypic subpopulations can reconstitute the immunophenotypic diversity in vivo. These findings indicate that the cell of origin and founding lesions, rather than an accumulation of distinct genomic alterations, prime tumour cells for lineage promiscuity. Moreover, these findings position MPAL in the spectrum of immature leukaemias and provide a genetically informed framework for future clinical trials of potential treatments for MPAL.

Abstract
Neuroblastoma (NB) is one of the most common solid tumors in children. High-risk NB remains lethal in about 50% of patients despite comprehensive and intensive treatments. Activation of PI3K/Akt/mTOR signaling pathway correlates with oncogenesis, poor prognosis and chemotherapy resistance in NB. Due to its central role in growth and metabolism, mTOR seems to be an important factor in NB, making it a possible target for NB. In this study, we investigated the effect of AZD8055, a potent dual mTORC1-mTORC2 inhibitor, in NB cell lines. Our data showed that mTOR signaling was extensively activated in NB cells. The activity of mTOR and downstream molecules were down-regulated in AZD8055-treated NB cells. Significantly, AZD8055 effectively inhibited cell growth and induced cell cycle arrest, autophagy and apoptosis in NB cells. Moreover, AZD8055 significantly reduced tumor growth in mice xenograft model without apparent toxicity. Taken together, our results highlight the potential of mTOR as a promising target for NB treatment. Therefore, AZD8055 may be further investigated for treatment in clinical trials for high risk NB.

Abstract
Purpose Osteonecrosis (ON) is a serious complication of the treatment of childhood acute lymphoblastic leukemia (ALL); however, data relating to ON in Asian pediatric patients with ALL are scarce. Therefore, we performed a retrospective analysis of cohorts of Japanese patients with ALL to clarify the incidence, clinical characteristics, and risk factors of ON. Patients and Methods The incidence and characteristics of ON were determined in patients with ALL (n = 1,662) enrolled in two studies from the Japan Association of Childhood Leukemia Study (JACLS) group (n = 635 and n = 1,027 patients treated with the ALL-97 and ALL-02 protocols, respectively). Results In total, 24 of 1,662 patients suffered from ON, of which 12 of 635 and 12 of 1,027 patients were treated with the ALL-97 and the ALL-02 protocol, respectively. Of the 24 patients, 23 were older than 10 years. In multivariate analysis, age (≥ 10 years) was the sole significant risk factor for ON ( P < .001). Separate evaluation of patients ≥ 10 years of age indicated a 5-year cumulative incidence of ON of 7.2% (95% CI, 4.0% to 12.6%) and 5.9% (95% CI, 3.3% to 10.4%) in the ALL-97 and the ALL-02 protocol, respectively, which was lower than reported previously, despite an administration of dexamethasone (DEX) similar to that in comparable studies; however, concomitant administration of DEX and l-asparaginase was reduced in the JACLS protocols. Conclusion We identified a low frequency of ON in the JACLS ALL-97 and ALL-02 studies. Although the sole risk factor for ON was age (≥ 10 years), even among high-risk patients, ON incidence was significantly lower than that reported in previous studies. These results suggest that, not only the total amount of DEX, but also how DEX and l-asparaginase are administered, which affects the clearance of DEX, may be associated with ON incidence in patients with ALL.

Abstract
Major depressive disorder (MDD) has been linked to differences in the volume of certain areas of the brain and to variants in the piccolo presynaptic cytomatrix protein (PCLO), but the relationship between PCLO and brain morphology has not been studied. A single-nucleotide polymorphism (SNP) in PCLO, rs2522833, is thought to affect protein stability and the activity of the hypothalamic-pituitary-adrenal axis. We investigated the relationship between cortical volume and this SNP in first-episode, drug-naive patients with MDD or healthy control subjects. Seventy-eight participants, including 30 patients with MDD and 48 healthy control subjects, were recruited via interview. PCLO rs2522833 genotyping and plasma cortisol assays were performed, and gray matter volume was estimated using structural magnetic resonance images. Among the individuals carrying the C-allele of PCLO rs2522833, the volume of the left temporal pole was significantly smaller in those with MDD than in healthy controls (family-wise error-corrected, P=0.003). No differences were detected in other brain regions. In addition, the C-carriers showed a larger volume reduction in the left temporal pole than those in the individuals with A/A genotype (P=0.0099). Plasma cortisol levels were significantly higher in MDD-affected C-carriers than in the healthy control C-carriers (12.76±6.10 vs 9.31±3.60 nm, P=0.045). We conclude that PCLO SNP rs2522833 is associated with a gray matter volume reduction in the left temporal pole in drug-naive, first-episode patients with MDD carrying the C-allele.

Abstract
BACKGROUND Quality of life (QOL) as a treatment outcome has not yet been evaluated among patients receiving a specific treatment regimen by treatment phase in a consistent manner. This exploratory cross-sectional study evaluated the QOL of children with acute lymphoblastic leukemia (ALL) receiving one of the most popular treatment regimens in Japan (Japan Association of Childhood Leukemia Study ALL-02 revised protocol). METHODS Children aged 5-18 years with newly diagnosed B-cell precursor ALL were included. The Pediatric Quality of Life Inventory™ 4.0 Generic Core Scales (PedsQL-J) were completed by children with ALL and their siblings, as well as by age- and sex-matched healthy controls. PedsQL Cancer Module (PedsQL-C) scores were also collected from children with ALL. RESULTS QOL in children with ALL of the consolidation phase group was significantly decreased compared with that of healthy controls, except in the area of emotional functioning. Regarding the maintenance phase group, QOL impairment was noted in the physical and school functioning, but no differences were noted in social functioning. The off-treatment group had a large effect size only for physical functioning, and the social functioning score was even better in children with ALL than in matched controls. QOL of children with ALL differed with treatment phase. Effect size varied with function and treatment phase. CONCLUSIONS QOL may change with the progression of treatment, and the timing of these changes varied according to function and problem.

Abstract
We have investigated antioxidant actions of acteoside (ACT) and another natural phenylpropanoid glycoside, cistanoside F (CIS-F) on lipid peroxidation in rat liver mitochondria (RLM) and rat liver mitochondrial lipid (RLML) liposomes induced by Fe(2+)/ADP. A synthetic ACT analogue, TX-1847, was also examined. Oxygen consumption, the formation of thiobarbituric acid reactive substances (TBARs) and glutathione concentration were determined simultaneously during lipid peroxidation. The radical scavenging activity of the compounds was evaluated by using 1,1-diphenyl-2-picrylhydrazyl. ACT and its analogs produced dose-dependent inhibitions of mitochondrial and liposomal lipid peroxidation (ACT ≈ CIS-F > TX-1847). Their radical scavenging activities were ranked as follows: TX-1847 > ACT > CIS-F. ACT, CIS-F, and TX-1847 spared reduced glutathione (GSH) during mitochondrial lipid peroxidation. The radical scavenging activities of the compounds did not parallel their anti-peroxidative activities. The data are consistent with the idea that the inhibitory activities of phenylpropanoids were primarily due to a radical chain-breaking mechanism. The sugar moieties in ACT and CIS-F, and/or the conformational structure of the compounds, also seem to play an important role in their inhibitory effects on lipid peroxidation.

Abstract
OBJECTIVE We previously reported that decrement of compound muscle action potential (CMAP) by repetitive nerve stimulation (RNS) was greater in the median nerves than in the ulnar nerves of patients with amyotrophic lateral sclerosis (ALS). The aim of this study was to evaluate whether CMAP decrement by RNS is a feasible marker for the differentiation of ALS from other diseases. MATERIALS & METHODS We performed RNS in the median and ulnar nerves of 51 patients with ALS and 40 patients with other diseases. RESULTS The CMAP decrement was significantly greater in the median nerves of patients with ALS, compared to the disease control patients. In the median nerves of patients with ALS, CMAP decrement was significantly greater in the cervical region-onset group than in the other region-onset group. CONCLUSIONS The finding of CMAP decrement in the median nerves can be useful for differentiating ALS patients with cervical region onset from other controls with active neuropathic diseases.
