Purpose: This study examined the factors that facilitated and obstructed the dissemination of a physical education lesson study (PELS) project in Peru, conducted in collaboration with Japan. Design/methodology/approach: Adopting a qualitative approach, five Peruvian stakeholders in the field of physical education (PE) were interviewed. All the interviews were transcribed. The data were analysed using the Steps for Coding and Theorization (SCAT). Findings: The factors that obstructed the dissemination of PELS were lack of mutual observation of lessons among teachers and the resistance of teachers to the project due to the term "study" in "lesson study". Conversely, online dissemination of PELS may significantly improve its position in Peru. Disseminating PELS through small group practice and deploying it in the field of education through stakeholder collaboration comprised facilitating factors. Originality/value: This study could facilitate an understanding of Peruvian educational and PE culture and have ripple effects on the practice and dissemination of LS in other countries and subject areas.

Introduction: Robotic‐assisted surgery has become increasingly popular because of its potential benefits. Anatomical liver resection (ALR) is a valuable strategy in hepatocellular carcinoma (HCC) management. ALR with indocyanine green (ICG) fluorescence navigation was reported as an effective solution for segment identification. We reported a simple and convenient "preoperative positive staining technique" for laparoscopic ALR to overcome some limitations. To our knowledge, this is the first report of robotic‐assisted surgery in which ALR was performed using this technique. Materials and Surgical Technique: A 69‐year‐old man presented with a 12‐mm HCC in segment 8. Preoperative three‐dimensional simulation images showed that the fourth‐order branch of the portal vein was a tumor‐bearing portal pedicle. After anesthesia induction, 1 mL of 0.025 mg/mL ICG was injected percutaneously into this branch under B‐mode ultrasound guidance before pneumoperitoneum. A robotic laparoscope was inserted. The preoperative positive staining area was clearly stained on the liver surface with the Firefly mode on the da Vinci Xi system. Based on the demarcation line, the liver parenchymal resection was started. The ICG fluorescence staining area was checked frequently on the resected side of the liver transection plane. Subsequently, the fourth‐order portal branch was identified with the ICG fluorescence technique and ligated. Finally, the specimen was resected. The operation took 352 min, with 10 mL of blood loss, and was completed without any operative problems. Discussion: Although many cases are required, the proposed preoperative positive staining technique appears useful for accurate and precise surgery given the increasing application of robotic‐assisted hepatectomy.

Hikikomori (a severe form of social withdrawal) is a serious mental health issue. A family approach is the initial step to support hikikomori; thus effective family intervention programs are warranted. We recently developed a 5‐day family intervention program (120 min weekly) based on Mental Health First Aid (MHFA) and Community Reinforcement and Family Training (CRAFT). In the present study, we modified the 5‐day program to a 3‐day program (180 min fortnightly), and examined the effectiveness of the 3‐day program using a single‐arm procedure. Data of 23 parents (four fathers and 19 mothers; age = 62.0 ± 9.1 years) were analyzed. Mental health conditions among participants themselves improved at the 4‐month follow‐up, but the confidence in hikikomori support declined and stigma toward mental health problems did not change. However, short‐term improvements in perceived skills in approaching hikikomori sufferers were detected. Hikikomori sufferers' actual behavioral changes, such as social participation or utilization of support, were also observed (six out of 20 hikikomori sufferers). Preliminary effectiveness was confirmed for the 3‐day program. Further revision of the program and a validation study with controls are required. [ABSTRACT FROM AUTHOR]

Abstract Background Several lines of evidence implicate orbitofrontal cortex dysfunction in the pathophysiology of obsessive-compulsive disorder (OCD). The purpose of this study was to investigate neuropsychological dysfunction of the orbitofrontal cortex in children with OCD. Methods The Iowa Gambling Task (IGT), which reflects orbitofrontal cortex function, and the Wisconsin Card Sorting Test (WCST), which is associated with functioning of the dorsolateral prefrontal cortex, were administered to 22 children with OCD and 22 healthy controls matched for gender, age, and intelligence. Results OCD patients displayed poor performance on the IGT. In contrast, performance on the WCST was not impaired in OCD patients compared to controls. Conclusions These findings are in line with previous studies demonstrating that OCD in childhood is associated with a dysfunction of orbitofrontal-striatal-thalamic circuitry.

Abstract Background The aims of this prospective study are to clarify the outcomes of child psychiatric inpatient treatment and to identify factors associated with patient improvement. Methods The attending psychiatrist used the Children's Global Assessment Scale (CGAS) to assess youths at admission to and discharge from a child and adolescent psychiatric unit in Japan(N = 126, mean age = 12.8, SD = 1.9). Hospital records gathered sociodemographic and clinical variables. In addition, youths and their primary caregivers assessed themselves using the Youth Self Report (YSR) and the Child Behavior Checklist (CBCL), respectively. Longitudinal analyses compared each scales' baseline and discharge scores. We also examined factors associated with changes in functioning (CGAS). Results Longitudinal comparisons revealed that CGAS, CBCL and YSR scores showed improvement over time (CGAS: t = -14.40, p = 0.00; CBCL: t = 3.80, p = 0.00; YSR: t = 2.40, p = 0.02). Linear regressions determined that the factors associated with improvement in CGAS included age, lower CGAS scores at admission, frequency of group therapy and psychiatric diagnosis. Conclusions This evaluation of children and adolescents in an inpatient unit demonstrated clinical improvement over time and identified factors associated with said improvement.

Purpose: Bile duct injury is one of the most serious complications of laparoscopic cholecystectomy. Intraoperative indocyanine green (ICG) cholangiography is a safe and useful navigation modality for confirming the biliary anatomy. ICG cholangiography is expected to be a routine method for helping avoid bile duct injuries. Patients and Methods: We examined 25 patients who underwent intraoperative cholangiography using ICG fluorescence. Two methods of ICG injection are used: intrabiliary injection (percutaneous transhepatic gallbladder drainage [PTGBD], gallbladder [GB] puncture and endoscopic nasobiliary drainage [ENBD]) at a dosage of 0.025 mg during the operation or intravenous injection with 2.5 mg ICG preoperatively. Results: There were 24 patients who underwent laparoscopic cholecystectomy and 1 patient who underwent hepatectomy. For laparoscopic cholecystectomy, the average operation time was 127 (50– 197) minutes, and estimated blood loss was 43.2 (0– 400) g. The ICG administration route was intravenous injections in 12 cases and intrabiliary injection in 12 cases (GB injection: 3 cases, PTGBD: 8 cases, ENBD:1 case). The course of the biliary tree was able to be confirmed in all cases that received direct injection into the biliary tract, whereas bile structures were recognizable in only 10 cases (83.3%) with intravenous injection. The postoperative hospital stay was 4.6 (3– 9) days, and no postoperative complications (Clavien–Dindo ≧IIIa) were observed. For hepatectomy, a tumor located near the left Glissonian pedicle was resected using a fluorescence image guide. Biliary structures were fluorescent without injury after resecting the tumor. No adverse events due to ICG administration were observed, and the procedure was able to be performed safely. Conclusion: ICG fluorescence imaging allows surgeons to visualize the course of the biliary tree in real time during cholecystectomy and hepatectomy. This is considered essential for hepatobiliary surgery to prevent biliary tree injury and ensure safe surgery. [ABSTRACT FROM AUTHOR]

Aims: As an extension of a phase 2/3 study evaluating the efficacy and safety of lisdexamfetamine dimesylate (LDX) 30, 50, or 70 mg/d for 4 weeks in Japanese patients aged 6‐17 years with attention‐deficit/hyperactivity disorder (ADHD), this study evaluated its long‐term safety and efficacy. Methods: This was a multicenter, open‐label study of LDX for 53 weeks. Safety was assessed by regular medical examination for treatment‐emergent adverse events (TEAEs); regular recording of body weight, vital signs, and laboratory test values; and completion of dependence questionnaires. Efficacy was assessed using Japanese versions of the ADHD‐Rating Scale‐IV (ADHD‐RS‐IV) and Conners' 3rd edition Parent Rating Scale (Conners 3); plus Clinical Global Impression‐Improvement (CGI‐I), Clinical Global Impression‐Severity, and Parent Global Assessment (PGA) scales. Results: Of 132 enrolled patients, 104 completed the trial. Most frequent treatment‐related TEAEs were decreased appetite (73.5%), initial insomnia (39.4%), and weight decrease (22.0%). Most TEAEs were mild (82.6% of patients). There were no serious or severe TEAEs or deaths. No treatment‐related TEAEs were associated with blood pressure or pulse rate, and no patient had a QTcF interval >500 ms. Statistically significant improvement from baseline to week 53 was observed in the mean ADHD‐Rating Scale‐IV total score and mean Conners 3 subscale scores. Most patients showed improvement on the CGI‐I (78%) and PGA (76.5%) scales. Conclusions: No significant safety issues were observed with LDX 30, 50, or 70 mg/d administered for 1 year in Japanese children and adolescents with ADHD. LDX was associated with long‐term reductions in ADHD symptoms and severity. [ABSTRACT FROM AUTHOR]

Intrathoracic hernias after total gastrectomy are rare. We report the case of a 78-year-old man who underwent total gastrectomy with antecolic Roux-Y reconstruction for residual gastric cancer. He had alcoholic liver cirrhosis and received radical laparoscopic proximal gastrectomy for gastric cancer 3 years ago. Early gastric cancer in the remnant stomach was found by routine upper gastrointestinal endoscopy. We initially performed endoscopic submucosal dissection, but the vertical margin was positive in a pathological result. We performed total gastrectomy with antecolic Roux-Y reconstruction by laparotomy. For adhesion of the esophageal hiatus, the left chest was connected with the abdominal cavity. A pleural defect was not repaired. Two days after the operation, the patient was suspected of having intrathoracic hernia by chest X-rays. Computed tomography showed that the transverse colon and Roux limb were incarcerated in the left thoracic cavity. He was diagnosed with intrathoracic hernia, and emergency reduction and repair were performed. Operative findings showed that the Roux limb and transverse colon were incarcerated in the thoracic cavity. After reduction, the orifice of the hernia was closed by suturing the crus of the diaphragm with the ligament of the jejunum and omentum. After the second operation, he experienced anastomotic leakage and left pyothorax. Anastomotic leakage was improved with conservative therapy and he was discharged 76 days after the second operation.

Background/Aim: The Questionnaire: Children with Difficulties (QCD) is a parent-assessed questionnaire designed to evaluate child’s difficulties in functioning during specific periods of the day. This study aimed to evaluate difficulties in daily functioning of children and adolescents with pervasive developmental disorder (PDD) using the QCD. Results were compared with those for a community sample. Methods: A case–control design was used. The cases comprised elementary school students (182 males, 51 females) and junior high school students (100 males, 39 females) with PDD, whereas a community sample of elementary school students (568 males, 579 females) and junior high school students (180 males, 183 females) was enrolled as controls. Their behavior was assessed using the QCD, the Tokyo Autistic Behavior Scale (TABS), the ADHD-rating scale (ADHD-RS), and the Oppositional Defiant Behavior Inventory (ODBI) for elementary and junior high school students, respectively. Effects of gender and diagnosis on the QCD scores were analyzed. Correlation coefficients between QCD and TABS, ADHD-RS, and ODBI scores were analyzed. Results: The QCD scores for the children with PDD were significantly lower compared with those from the community sample (P < 0.001). Significantly strong correlations were observed in more areas of the ADHD-RS and ODBI scores compared with the TABS scores. Conclusions: Children with PDD experienced greater difficulties in completing basic daily activities; moreover, their QCD scores revealed stronger associations with their ADHD-RS and ODBI scores in comparison with their TABS scores. The difficulties of PDD, ADHD and OBDI symptoms combined in children makes it necessary to assess all diagnoses before any therapy for PDD is initiated in order to be able to evaluate its results properly.

Background: The 2011 Japan massive tsunami traumatized many children. The aim of this study was to assess changes in strengths and difficulties experienced in home and school by among surviving children after the 2011 tsunami, in comparison with published normal Japanese data. Methods: In November 2012 (20 months after the disaster) and September 2013 (30 months after the disaster), the Strengths and Difficulties Questionnaire (SDQ), a questionnaire on children's strengths and difficulties in home and school activities, were distributed to 12,193 and 11,819 children, respectively. An effective response of children 20 months and 30 month after the disaster was obtained in 10,597 children (86.9%), and 10,812 children (91.4%), respectively. The SDQ scores evaluated by parents and teachers were compared with published normal Japanese SDQ scores. Results: The SDQ scores (emotional problems, conduct problems, hyperactivity/inattention, peer relationship problems, and total difficulty score) evaluated by parents of children in the 4th to 9th grade who were evaluated after 30 and 20 months were significantly high compared with the published normal data of children without traumatic experiences (all P<0.001). The SDQ scores (prosocial behavior) evaluated by teachers of children in the 4th to 9th grade who were evaluated after 30 and 20 months were significantly low compared with the published normal data of children without traumatic experiences (all P<0.001). Conclusions: This study showed that the experience of the disaster affected those children with prosocial behaviors towards teachers and friends at school. However, no significant changes (in their prosocial attitude) had been seen at home, where they continued to keep their respect and caring feelings for parents. These results indicate that for accurate diagnosis, clinicians should not only evaluate these children's daily activities at home but also try to objectively assess their daily activities at school.

Background: On March 11, 2011, Japan was struck by a massive earthquake and tsunami. The tsunami caused tremendous damage and traumatized several people, including children. The aim of this study was to assess changes in traumatic symptoms 8, 20, and 30 months of the 2011 tsunami. Methods: The study comprised three groups. Copies of the Post-Traumatic Stress Symptoms for Children 15 items (PTSSC-15), a self-rating questionnaire on traumatic symptoms, were distributed to 12,524 children (8-month period), 12,193 children (20-month period), and 11,819 children (30-month period). An effective response of children 8 months, 20 months, and 30 month after the disaster was obtained in 11,639 (92.9%), 10,597 (86.9%), and 10,812 children (91.4%), respectively. We calculated the total score, PTSD subscale, and Depression subscale of PTSSC-15. We calculated the total score, PTSD subscale, and Depression subscale of PTSSC-15. Results: The PTSSC-15 total score and PTSD subscale of children belonging to 1st–9th grade groups who were tested 30 and 20 months after the tsunami significantly decreased compared with those of children tested 8 months after the tsunami. The PTSSC-15 total score and PTSD subscale of children in 1st–9th grade groups tested after 30 months did not decrease significantly compared with those of children tested after 20 months. The PTSSC-15 Depression subscale and PTSD subscale of children in 1st–9th grade groups tested after 30 months significantly decreased compared with those of children tested 8 months after the tsunami. The PTSSC-15 Depression subscale of children in 1st–9th grade groups evaluated after 30 months significantly decreased compared with those of children evaluated after 20 months. Conclusions: This study demonstrates that the traumatic symptoms of children who survived the massive tsunami improved with time. Nonetheless, the traumatic symptoms, which in some cases did not improve with time. [ABSTRACT FROM AUTHOR]

Background: On March 11, 2011, Japan was struck by a massive earthquake and tsunami. The tsunami caused tremendous damage and traumatized a number of people, including children. This study aimed to compare traumatic symptoms and daily life activity among children 20 months after the 2011 Great East Japan Earthquake and Tsunami with those observed after 8 months. Methods: The study comprised two groups. The first comprised 12,524 kindergarten, elementary school, and junior high school children in Ishinomaki City, Miyagi Prefecture, Japan, who were evaluated 8 months after the disaster. The second comprised 10,597 children from the same place who were evaluated 20 months after the disaster. The Post Traumatic Stress Symptoms for Children 15 items (PTSSC-15), a self-completion questionnaire on traumatic symptoms, and a questionnaire on children's daily life were distributed to the children. An effective response was obtained from 11,639 (92.9%, 8 months after) and 10,597 (86.9%, 20 months after) children. Results: The PTSSC-15 score was significantly higher in junior high school girls than in boys. The PTSSC-15 score was significantly higher in 4th–6th grade girls than in boys after 8 months. Elementary and junior high school children evaluated after 20 months had a significantly lower PTSSC-15 score than those evaluated after 8 months. The number of children having breakfast was significantly higher after 8 months than that after 20 months. In both the groups, children of all grades who had breakfast had a significantly lower PTSSC-15 score than those who did not have breakfast. Conclusions: We conclude that traumatic symptoms and daily life activity of children who survived the earthquake and tsunami improved over time. [ABSTRACT FROM AUTHOR]

AIM: The aim of this study was to evaluate the frontopolar hemodynamic response and depressive mood in children with mild or moderate major depressive disorder during six weeks treatment without medication. METHODS: The subjects were 10 patients with mild or moderate depression. They were depressive drug-naive children and adolescents. The scores of Depression Self Rating Scale (DSRS), the results of the Verbal Fluency Test (VFT), and the concentrations of oxy-hemoglobin (Oxy-Hb) of frontal pole brain assessed by two-channel near infrared spectroscopy (NIRS) after six weeks of treatment was compared with those of initial treatment. RESULTS: The score of DSRS was significantly reduced after six weeks of initial treatment (p<0.001, t-test). The word number of VFT was not significantly changed after six weeks of treatment. The oxy-Hb concentration significantly increased after six weeks of treatment (p<0.001, t-test). CONCLUSIONS: This study demonstrated that the concentration of oxy-Hb of frontopolar cortex in children with mild and moderate depression improved along with their depressive mood. These results suggested that concentration of oxy-Hb using NIRS may be used as the state maker for change in depressive mood of children having depression, similar to that in adults.

Background: The aim of this study was to evaluate the reliability and validity of the Questionnaire-Children with Difficulties (QCD), which was developed for the evaluation of children's daily life behaviors during specified periods of the day. Methods: The subjects were 1,514 Japanese public elementary and junior high school students. For the examination of reliability, Cronbach's alpha was calculated to assess the internal consistency of the questionnaire. With regard to validity, correlation coefficients were calculated to examine whether QCD scores correlated with those of the ADHD-Rating Scale (ADHD-RS) and the Oppositional Defiant Behavior Inventory (ODBI). Results: Cronbach's alpha coefficient for the total score of the QCD was .876. The correlation coefficients of the QCD score with ADHD-RS and ODBI scores were -.514 and -.577, respectively. Conclusions: The internal consistency and validity of the QCD were demonstrated. The QCD is a reliable and valid instrument for evaluating daily life problems for children during different time periods of the day. [ABSTRACT FROM AUTHOR]

Background: To elucidate relationships between disaster damage conditions and sleep duration among children who survived the 2011 Japan earthquake and tsunami. Methods: The subjects comprised 12,524 children in kindergartens, elementary schools, and junior high schools in Ishinomaki City, Miyagi Prefecture, Japan. The Post Traumatic Stress Symptoms for Children 15 items (PTSSC-15), a self-completion questionnaire on traumatic symptoms, and a sleep questionnaire were distributed to them. A questionnaire regarding disaster damage conditions of the children’s homes was distributed to their teachers. Of 12,524, an effective response was obtained from 11,692 (93.3%). Results: Relationships between sleep duration and traumatic symptoms were displayed low correlations. Children with house damage and/or evacuation experiences slept for a significantly shorter time than children without these experiences. Conclusion: It is critical not only to examine traumatic symptoms in children but also to collect sleep duration and disaster damage conditions following natural disasters. [ABSTRACT FROM AUTHOR]

Background: To evaluate relationships between traumatic symptoms and environmental damage conditions among children who survived the 2011 Great East Japan Earthquake and Tsunami. Methods: The subjects were 12,524 children in kindergartens, elementary schools, and junior high schools in Ishinomaki City, Miyagi Prefecture, Japan. The Post Traumatic Stress Symptoms for Children 15 items (PTSSC-15), a self-completion questionnaire on traumatic symptoms, was distributed to the children and a questionnaire regarding environmental damage conditions affecting the children was distributed to their teachers. Of 12,524 questionnaires distributed, an effective response was obtained from 11,692 (93.3%). Results: The PTSSC-15 score was significantly higher in females than in males among 4th to 6th grade students in elementary schools and among junior high school students. In terms of traumatic symptoms and environmental damage conditions, with the exception of kindergartners, children who had their houses damaged or experienced separation from family members had a significantly higher PTSSC-15 score than children who did not experience environmental damage. Except for kindergartners and 4th- to 6th-grade elementary school students, children who experienced evacuation had a significantly higher PTSSC-15 score. Conclusions: This study demonstrated relationships between traumatic symptoms and environmental damage conditions in children who had suffered from the disaster. Factors examined in studying the relationship between environmental damage conditions and traumatic symptoms were gender, age, house damage, evacuation experience, and bereavement experience. It was critical not only to examine the traumatic symptoms of the children but also to collect accurate information about environmental damage conditions. [ABSTRACT FROM AUTHOR]

Five species of Clusiidae (Diptera), Craspedochaeta biseta (Hendel), hendeli a plumosa (Sasakawa), Heteromeringia sexramifera Sueyoshi, Phylloclusia yambarensis sp. n., and Sobarocephala uncinata Sueyoshi, were collected from log emergence traps installed in a subtropical forest of Japan from February 2006 to February 2008. Craspedochaeta biseta (Hendel) was newly recorded in Japan. Wood debris was gathered from 1–22 year old secondary stands managed by the improvement cutting of natural forest (ICNF) and unmanaged stands, and categorized by stage of decay and size, and then enveloped in fine net bags (emergence trap). In total, 84 clusiid adults were obtained. Most were reared from wood debris in an advanced stage of decay and from 2 year old or older managed and unmanaged forest stands, although P. yambarensis was reared from wood debris in an early stage of decay and from 1 year old forests after cuttings. Log emergence traps effectively sample clusiids, taking both sexes in approximately equal numbers. Specimens collected by this trap may resolve the difficulty in identifying male and female specimens of several clusiid species that show sexual dimorphism. [ABSTRACT FROM AUTHOR]
