Abstract
INTRODUCTION Unintended teenage pregnancies have become a global public health challenge, particularly in sub-Saharan Africa. There is a notably high prevalence of unintended pregnancies among unmarried teenagers in Uganda. This study will develop an intervention programme using mobile money shops (vendors) as a platform to deliver sexual and reproductive health and rights (SRHR) services to teenagers and assess its effectiveness and scalability in Uganda. METHODS AND ANALYSES This hybrid study comprises two integral components: an intervention study to assess the effectiveness of vendor-mediated intervention and implementation research to evaluate the implementation process. 30 vendors will be recruited for both intervention and control arms in 2 municipalities in Eastern Uganda, which have a high unintended pregnancy prevalence rate among unmarried teens aged 15-19 years. A preintervention and postintervention repeated survey involving 600 participants for each arm will be conducted over 4 months. The primary outcome is the rate of condom users among teenage vendor users. The secondary outcomes include the rate of preference for receiving SRHR services at vendors and knowledge regarding SRHR. A difference-in-differences analysis will be used to determine the effectiveness of the intervention. The Bowen model will be employed to evaluate the implementation design. ETHICS AND DISSEMINATION Ethical approval was obtained from the Ethics Review Committee of Uganda Christen University and JICA Ogata Sadako Research Institute for Peace and Development in Japan. The findings will be widely disseminated. This study was registered with the University Hospital Medical Information Network in Japan (UMIN000053332) on 12 January 2024. TRIAL REGISTRATION NUMBER UMIN000053332.

Abstract
INTRODUCTION In the context of collective efforts taken in Japan to control the spread of COVID-19, the state of emergency and social distancing have caused a negative impact on the mental health of all residents, including foreign communities in Japan. This study aimed to evaluate the level of anxiety and its associated factors among non-Japanese residents residing in Japan during the COVID-19 pandemic. METHODS A web-based survey in 13 languages was conducted among non-Japanese residents living in Japan during the COVID-19 situation. The State-Trait Anxiety Inventory assessed the level of anxiety-State (STAI-S) scores prorated from its six-item version. The multivariable logistic regression using the Akaike Information Criterion (AIC) method was performed to identify the associated factors of anxiety among participants. RESULTS From January to March 2021, we collected 392 responses. A total of 357 valid responses were analyzed. 54.6% of participants suffered from clinically significant anxiety (CSA). In multivariable logistic model analysis, the CSA status or the high level of anxiety was associated with three factors, including having troubles/difficulties in learning or working, decreased sleep duration, and decreased overall physical health (p<0.05). CONCLUSION Our study suggests several possible risk factors of anxiety among non-Japanese residents living in Japan undergoing the COVID-19 pandemic, including the troubles or difficulties in learning or working, the decrease in sleep duration, and the decrease in overall physical health.

Abstract
Alveolar echinococcosis is a zoonotic disease caused by a larval-stage Echinococcus multilocularis infection. Geographical haplotyping targeting the parasite's mitochondrial cytochrome b (cob) gene has been reported for isolates from definitive and intermediate hosts (wild canids and rodents); however, there are limited reports on strain typing for the dead-end host, the horse, which could act as a sentinel for E. multilocularis. Accordingly, we investigated the diversity of E. multilocularis in isolates obtained from slaughtered Japanese and Canadian horses originating from the Iburi and Hidaka regions in Hokkaido and from Alberta, respectively, with PCR and haplogroup analyses targeting cob gene sequences obtained. Seventy horses were diagnosed with alveolar echinococcosis based on histopathology and cob-gene PCR testing. The E. multilocularis detected in these horses was classified as either an Asian (for Hokkaido-raised horses) or a European (for Alberta-raised horses) haplogroup, based on the obtained cob-gene sequence analysis. In addition, haplotype network analysis revealed that E. multilocularis isolated from Hokkaido-raised horses is highly homologous to Kazakhstan isolates, and E. multilocularis isolated from Alberta-raised horses is highly homologous to Austrian isolates. The results of this study suggest that cob-gene-targeted PCR analysis could be useful for the geographical genetic characterization of E. multilocularis isolated from horses.

Abstract
Video-assisted thoracic surgery esophagectomy (VATS-E) may increase the risk of postoperative nausea and vomiting (PONV) because it uses a high dosage of anesthesia through a long operative duration. However, no study has examined the risk factors for PONV after VATS-E. Therefore, we investigated the risk factors for PONV to support the appropriate risk management of PONV after VATS-E. This prospective cohort study included 155 patients who underwent VATS-E at the Showa University Hospital between April 1st, 2020 and November 30th, 2022. The primary outcome was the incidence of PONV within 24 h after surgery. Significant independent risk factors associated with the incidence of PONV were selected using multivariate analysis. The association between the number of risk factors for PONV and incidence of PONV was analyzed. One-hundred fifty-three patients were included in the analysis. The patients' median age was 67 years (range, 44-88), and 79.1% were male. PONV occurred in 35 (22.9%) patients. In the multivariate analysis, remifentanil dosage > 89.0 ng/kg/ min, albumin ≤ 3.5 g/dL, and eGFR < 60 mL/min/1.73 m 2 were independent significant risk factors for PONV. A significant association was observed between the incidence of and the number of risk factors for PONV (0 factor, 5.8%; 1 factor, 27.3%; ≥ 2 factors, 40.0%; p = 0.001). These three risk factors are useful indicators for selecting patients at high risk of developing PONV after VATS-E. In these patients, avoiding the development of PONV will be possible by performing appropriate risk management.

Abstract
Laparoscopic cystectomy for mature teratomas is associated with a high incidence of intraperitoneal spillage and tumor spread; however, extragonadal recurrence of this benign tumor is rare. We hereby present an additional case of extragonadal mature teratoma that recurred in the pouch of Douglas after ovarian cystectomy. A 43-year-old Japanese woman presented with atypical genital bleeding. A 7 cm mature teratoma was detected using transvaginal ultrasonography and magnetic resonance imaging. At 26 years old, she underwent bilateral cystectomy for bilateral mature teratoma of the ovary. During laparoscopic surgery, a cystic tumor appeared in the pouch of Douglas and was firmly adhered to the surrounding tissues. Both ovaries were normal. The resected tumor was diagnosed as extragonadal, benign, mature teratoma. To avoid the extragonadal recurrence of mature teratoma, removal of tumor contents from intraperitoneal spillage by lavage should be performed at the end of surgery.

Abstract
PURPOSE To evaluate changes in intraocular pressure (IOP) at different gaze positions before and after superior rectus muscle-lateral rectus muscle (SR-LR) loop myopexy in highly myopic strabismus (HMS). STUDY DESIGN Nonrandomized clinical, prospective, interventional trial. METHODS Fourteen patients with HMS (18 eyes) who underwent SR-LR loop myopexy were divided into 3 groups: < 100 prism diopters (PD) (mild esotropia [ET] group), > 100 PD (large ET group), and > 100 PD, and simultaneous recession of the medial rectus (MR) muscle was performed (large ET + MR group). Intraocular pressure was measured preoperatively and postoperatively at the primary, abduction, and adduction positions in each group. RESULTS Intraocular pressure did not change after surgery in the mild ET group. Intraocular pressure significantly decreased in the abduction position (from 20.0 ± 2.1 to 16.0 ± 1.9 mmHg, P = 0.043) in the large ET group and in the abduction (from 22.2 ± 5.9 to 15.6 ± 4.3 mmHg, P = 0.048) and primary positions (from 15.8 ± 5.0 to 10.2 ± 2.8 mmHg, P = 0.043) in the large ET + MR group. The preoperative significant differences in IOP between the abduction and adduction positions in the large ET group (7.4 ± 3.4 mmHg) and the large ET + MR group (10.0 ± 5.5 mmHg) disappeared postoperatively (3.2 ± 2.8 mmHg and 3.6 ± 1.7 mmHg, respectively). The differences in IOP between abduction and adduction were similar in all the groups. CONCLUSION SR-LR loop myopexy decreased IOP in patients with HMS in the abduction and primary positions.

Abstract
Purpose To report stereopsis after bilateral Yokoyama procedure in patients with highly myopic strabismus and good visual acuity. Observations Five patients aged between 34 and 81 years with best-corrected visual acuity of 20/25 or better were operated on. The preoperative strabismus angle ranged from esotropia of 35-113 prism diopters (PD) at distance and esotropia of 40-113 PD at near. One patient had left hypotropia of 4 PD and excyclotorsion of 15°, and the other had left hypotropia of 10 PD. Their axial lengths were 27.65-33.07 mm, and the posterior globe dislocation angles were between 123 and 148° on coronal magnetic resonance imaging (MRI). Limitations of abduction were between -1 and -2. All patients complained of diplopia, and none of them showed stereopsis. The Yokoyama procedure was performed on both eyes. Postoperative alternate cover testing showed from esotropia of 2 PD to exophoria of 8 PD at distance and from exotropia of 12 PD to esophoria of 10 PD at near.Three patients recovered stereopsis of 100, 50, and 140 sec, respectively. Two cases required unilateral inferior rectus muscle recessions, and their postoperative stereopsis was 25 and 50 sec. Conclusions and Importance The Yokoyama procedure is effective not only in cases of heavy eye syndrome but also in cases of myopic esotropia associated with a globe dislocation angle of 120° or with little abduction restriction. If visual acuity is good, stereopsis may be restored with improvement in eye deviation.

Abstract
BACKGROUND Size at birth, an indicator of intrauterine growth, has been studied extensively in relation to subsequent health, growth and developmental outcomes. Our umbrella review synthesises evidence from systematic reviews and meta-analyses on the effects of size at birth on subsequent health, growth and development in children and adolescents up to age 18, and identifies gaps. METHODS We searched five databases from inception to mid-July 2021 to identify eligible systematic reviews and meta-analyses. For each meta-analysis, we extracted data on the exposures and outcomes measured and the strength of the association. FINDINGS We screened 16 641 articles and identified 302 systematic reviews. The literature operationalised size at birth (birth weight and/or gestation) in 12 ways. There were 1041 meta-analyses of associations between size at birth and 67 outcomes. Thirteen outcomes had no meta-analysis.Small size at birth was examined for 50 outcomes and was associated with over half of these (32 of 50); continuous/post-term/large size at birth was examined for 35 outcomes and was consistently associated with 11 of the 35 outcomes. Seventy-three meta-analyses (in 11 reviews) compared risks by size for gestational age (GA), stratified by preterm and term. Prematurity mechanisms were the key aetiologies linked to mortality and cognitive development, while intrauterine growth restriction (IUGR), manifesting as small for GA, was primarily linked to underweight and stunting. INTERPRETATION Future reviews should use methodologically sound comparators to further understand aetiological mechanisms linking IUGR and prematurity to subsequent outcomes. Future research should focus on understudied exposures (large size at birth and size at birth stratified by gestation), gaps in outcomes (specifically those without reviews or meta-analysis and stratified by age group of children) and neglected populations. PROSPERO REGISTRATION NUMBER CRD42021268843.

Abstract
Introduction Osteoarthritis (OA) is the most common form of arthritis. OA results from the breakdown of cartilage, which leads to deterioration of the entire joint and the connective tissue that holds the joint together, and gradually and irreversibly worsens over time. Adipose-derived stem/stromal cells (ADSCs) have been used in the treatment of knee OA. However, the safety and efficacy of ADSC treatment of OA remain unclear. In this study, we investigated the pathophysiology of severe knee arthritis that occurred after ADSC treatment by screening for autoantibodies in synovial fluid from patients who received ADSC treatment. Methods Adult Japanese patients with OA who received ADSC treatment at Saitama Cooperative Hospital between June 2018 and October 2021 were enrolled. Antibodies (Abs) were screened using immunoprecipitation (IPP) with [35S]-methionine-labeled HeLa cell extracts. The detected protein was identified by liquid chromatography coupled with time-of-flight mass spectrometry (MS) and ion trap MS, and the corresponding proteins were confirmed as autoantigens using immunoblotting. Ab titers were measured using an enzyme-linked immunosorbent assay. Results A total of 113 patients received ADSC treatment, and 75% (85/113) received ADSC injection at least twice with a 6-month interval between. No obvious abnormalities were observed in any patient after their first treatment; by contrast, 53% (45/85) of patients who received their second or third ADSC injection showed severe knee arthritis. IPP detected a common anti-15 kDa Ab in synovial fluid of 62% (8/13) of the samples analyzed from patients who showed severe arthritis. This Ab was not detected in synovial fluid obtained from the same joints before treatment. The corresponding autoantigen was identified as histone H2B. All available synovial samples from patients who tested positive for anti-histone H2B Ab were newly positive after the treatment; that is, none had been positive for anti-histone H2B Ab before treatment. Conclusions Multiple ADSC injections for OA induced severe arthritis in a high percentage of patients, particularly after the second injection. Synovial fluid from some patients with knee arthritis contained Ab to histone H2B that appeared only after ADSC treatment. These findings provide new insights into the pathogenesis of ADSC treatment-induced severe arthritis.

Abstract
PURPOSE To describe clinical presentations of acquired comitant esotropia and digital device use in children, adolescents, and young adults without neurological problems. STUDY DESIGN Multicenter prospective observational study. METHODS Patients with acquired comitant esotropia, without intracranial diseases aged 5-35 years at the time of visit, who were seen at pre-registered facilities within 1 year of onset were enrolled. The duration from the onset of symptoms and the time of digital device usage approximately 1 month before onset and their lifestyles were surveyed. Visual acuity, cycloplegic refraction, and strabismus angles were measured. Data were analyzed in three age groups (Child: 5-12 years, Adolescent: 13-18 years, and Young adult: 19-35 years). RESULTS Between November 2019 and December 2021, 218 patients were enrolled from 55 facilities, and 194 patients (including 62 children, 69 adolescents, and 63 young adults) were analyzed. The child group spent the least amount of time using digital devices (children: 159; adolescents: 210; young adults: 267 min/work day, p < 0.05; (mean time in the same order below) 229, 338, 314 min/holiday, p < 0.05) and had the largest strabismus angle (mean strabismus angle at near: 30, 22, 18 PD, p < 0.01; at far: 28, 26, 21 PD, p<0.05). CONCLUSION The clinical features of acquired comitant esotropia and hand-held digital device usage differed between children aged ≤ 12 years and older patients. This report gives the current clinical characteristics of young patients with acquired esotropia and digital device usage.

Abstract
Introduction By linking datasets, electronic records can be used to build large birth-cohorts, enabling researchers to cost-effectively answer questions relevant to populations over the life-course. Currently, around 5.8 million Palestinian refugees live in five settings: Jordan, Lebanon, Syria, West Bank, and Gaza Strip. The United Nations Relief and Works Agency for Palestine Refugees in the Near East (UNRWA) provides them with free primary health and elementary-school services. It maintains electronic records to do so.We aimed to establish a birth cohort of Palestinian refugees born between 1st January 2010 and 31st December 2020 living in five settings by linking mother obstetric records with child health and education records and to describe some of the cohort characteristics. In future, we plan to assess effects of size-at-birth on growth, health and educational attainment, among other questions. Methods We extracted all available data from 140 health centres and 702 schools across five settings, i.e. all UNRWA service users. Creating the cohort involved examining IDs and other data, preparing data, de-duplicating records, and identifying live-births, linking the mothers' and children's data using different deterministic linking algorithms, and understanding reasons for non-linkage. Results We established a birth cohort of Palestinian refugees using electronic records of 972,743 live births. We found high levels of linkage to health records overall (83%), which improved over time (from 73% to 86%), and variations in linkage rates by setting: these averaged 93% in Gaza, 89% in Lebanon, 75% in Jordan, 73% in West Bank and 68% in Syria. Of the 423,580 children age-eligible to go to school, 47% went to UNRWA schools and comprised of 197,479 children with both health and education records, and 2,447 children with only education records. In addition to year and setting, other factors associated with non-linkage included mortality and having a non-refugee mother. Misclassification errors were minimal. Conclusion This linked open birth-cohort is unique for refugees and the Arab region and forms the basis for many future studies, including to elucidate pathways for improved health and education in this vulnerable, understudied population. Our characterization of the cohort leads us to recommend using different sub-sets of the cohort depending on the research question and analytic purposes.

Abstract
Snakebite envenoming is a potentially life-threatening global public health issue with Bangladesh having one of the highest rates of snakebite cases. The Bede, a nomadic ethnic group in Bangladesh, traditionally engages in snake-related business such as snake charming. The Bede relies on their own ethnomedicinal practitioners for snakebite treatment while there is a lack of concrete evidence on the effectiveness of such ethnomedicinal treatment. To identify the barriers to the utilization of biomedical treatment for snakebite we conducted interviews with 38 Bede snake charmers, who have experienced snakebite, and six family members of those who died of snakebite. Our results show that four critical barriers, Accessibility, Affordability, Availability, and Acceptability (4As), prevented some of the Bede from seeking biomedical treatment. Moreover, we found that a few Bede died of a snakebite every year. There are survivors of snakebite who were able to receive biomedical treatment by overcoming all of the 4As. Our results provide insights into the current state of snakebite treatment in Bangladesh and can inform the development of more effective and accessible treatment options for those affected. Partnership between the public sector and the Bede community has the potential to make a significant impact in reducing snakebite morbidity and mortality in Bangladesh.

Abstract
BACKGROUND Axial spondylometaphyseal dysplasia(axial SMD) is associated with early-onset retinal dystrophy and various skeletal dysplasias of varying severity. NEK1 is the causative gene for short rib polydactyly syndrome and axial SMD. Here, we report a case of siblings with juvenile retinitis pigmentosa (RP) and NEK1 variants not associated with systemic disorders. MATERIALS AND METHODS The patients were a 7-year-old-girl and a 9-year-old boy with RP, who were followed for 9 years. Whole exome sequencing (WES) was performed on the siblings and their parents, who were not consanguineous. RESULTS The corrected visual acuity of the girl and the boy at first visit was binocular 20/63 and 20/100 OD and 20/63 OS, respectively. The siblings had narrowing of retinal blood vessels and retinal pigment epithelium atrophy in the fundus and showed an extinguished pattern in electroretinogram. On optical coherence tomography, there was a mottled ellipsoid band with progressive loss in the outer macular, the edges of which corresponded to the ring of hyperautofluorescence on fundus autofluorescence imaging. The siblings showed progressive visual field constriction. Radiological examination did not reveal any skeletal abnormalities. We identified two rare heterozygous NEK1 variants in the patients: c.240 G>A; p.(M80I) and c.634_639dup;p.(V212_L213dup). Heterozygous variants were recognized in the father and mother, respectively. According to the guidelines of the American College of Medical Genetics and Genomics, both variants were classified as likely pathogenic. CONCLUSION This is the first report of RP patients with NEK1 variants not associated with skeletal abnormalities.

Abstract
OBJECTIVES Lifestyle behaviours associated with the incidence of type 2 diabetes mellitus (T2DM) need further clarification using health insurance data. STUDY DESIGN This is a cohort study. METHODS In 2015, 193,246 participants aged 40-74 years attended the specific health checkups and were observed up to 2020 in Fukushima, Japan. Using the principal component analysis, we identified two patterns from ten lifestyle behaviour questions, namely, the "diet-smoking" pattern (including smoking, alcohol drinking, skipping breakfast, eating fast, late dinner, and snacking) and the "physical activity-sleep" pattern (including physical exercise, walking equivalent activity, walking fast, and sufficient sleep). Then, individual pattern scores were calculated; the higher the scores, the healthier the behaviours. RESULTS The accumulative incidence rate of T2DM was 630.5 in men and 391.9 in women per 100,000 person-years in an average of 4 years of follow-up. Adjusted for the demographic and cardiometabolic factors at the baseline, the hazard ratio (95% confidence interval) of the highest versus lowest quartile scores of the "diet-smoking" pattern for T2DM risk was 0.82 (0.72, 0.92; P for trend = 0.002) in men and 0.87 (0.76, 1·00; P for trend = 0.034) in women; that of the "physical activity-sleep" pattern was 0.92 (0.82, 1·04; P for trend = 0.0996) in men and 0.92 (0.80, 1·06; P for trend = 0.372) in women. The "physical activity-sleep" pattern showed a significant inverse association in non-overweight men. CONCLUSIONS Lifestyle behaviour associated with a healthy diet and lack of smoking may significantly lower the risk of T2DM in middle-aged Japanese adults.

Abstract
Leber congenital amaurosis (LCA) is the most severe form of inherited retinal dystrophy. RPGRIP1-related LCA accounts for 5-6% of LCA. We performed whole-exome sequencing and whole-genome sequencing (WGS) on 29 patients with clinically suspected LCA and examined ophthalmic findings in patients with biallelic pathogenic variants of RPGRIP1. In addition to five previously reported cases, we identified five cases from four families with compound heterozygous RPGRIP1 variants using WGS. Five patients had null variants comprising frameshift variants, an Alu insertion, and microdeletions. A previously reported 1339 bp deletion involving exon 18 was found in four cases, and the deletion was relatively prevalent in the Japanese population (allele frequency: 0.002). Microdeletions involving exon 1 were detected in four cases. In patients with RPGRIP1 variants, visual acuity remained low, ranging from light perception to 0.2, and showed no correlation with age. In optical coherence tomography images, the ellipsoid zone (EZ) length decreased with age in all but one case of unimpaired EZ. The retinal structure was relatively preserved in all cases; however, there were cases with great differences in visual function compared to their siblings and a 56-year-old patient who still had a faint EZ line. Structural abnormalities may be important genetic causes of RPGRIP1-related retinal dystrophy in Japanese patients, and WGS was useful for detecting them.

Abstract
BACKGROUND Fertility declines with age, but it remains important to protect women from unplanned pregnancies throughout their reproductive lives. The objective of this study was to describe factors that influence modern contraceptive use among women aged 35 to 49 years and their male partners in Gomoa West District of Ghana. METHODS In-depth interviews were conducted remotely for 22 women, 15 male partners of the women interviewed and seven family planning (FP) providers. In all, a total of 44 participants took part in the study. Seven refusals were recorded, four females and three males. Four focus group discussions were organized for 21 participants who took part in the in-depth interviews. Data collected were transcribed and coded after exporting to Nvivo12 qualitative analysis software. Thematic analysis was undertaken using an abductive approach. RESULTS Factors that influenced the use of modern contraceptives included: achieved desired family size, providing for the family, counselling by health professionals, influence of the male partner, and health reasons. Barriers cited included: religious or socio-cultural reasons, experience or fear of side effects, rumors or misconceptions, declining fertility, and the belief that contraceptive use is a matter for women. Within the study group, roughly half of women used modern contraceptives, while the majority of male partners were non-users. CONCLUSION Contraception among women aged 35 to 49 years and their male partners is influenced by several factors such as achieved desired family size, influence of the male partner, rumors or misconceptions, and declining fertility. Strengthening male involvement in family planning activities and health educational activities could alleviate fear and reduce misconceptions about using modern contraceptives.

Abstract
Mobile intrinsic localized modes (ILMs) in balanced nonlinear capacitive-inductive cyclic transmission lines are studied by experiment, using a spatiotemporal driver under damped steady-state conditions. Without nonlinear balance, the experimentally observed resonance between the traveling ILM and normal modes of the nonlinear transmission line generates lattice drag via the production of a lattice backwave. In our experimental study of a balanced running ILM in a steady state, it is observed that the fundamental resonance can be removed over extended, well-defined driving frequency intervals and strongly suppressed over the complete ILM driving frequency range. Because both of these nonlinear capacitive and inductive elements display hysteresis our observation demonstrates that the experimental system, which is only partially self-dual, is surprisingly tolerant, regarding the precision necessary to eliminate the ILM backwave. It appears that simply balancing the cell dual nonlinearities makes the ILM envelope shape essentially the same at the two locations in the cell, so that the effective lattice discreteness seen by the ILM nearly vanishes.

Abstract
PURPOSE To report the characteristics of the steroid-induced ocular hypertensive response in pediatric patients with acute lymphoblastic leukemia (ALL) treated with prednisolone (PSL) during induction therapy and with dexamethasone (DEX) during reinduction therapy. STUDY DESIGN Retrospective. PATIENTS AND METHODS This study included pediatric patients diagnosed with B-cell precursor ALL and treated with systemic corticosteroids sometime during the period from 2016 to 2018 at Shizuoka Children's Hospital. Data were extracted from the hematology/oncology records related to the type, dose, and duration of systemic corticosteroids as well as to the ophthalmologic examination findings, intraocular pressure (IOP) data, symptoms of high IOP, and antiglaucoma medications obtained during corticosteroid administration. The maximal IOPs of the PSL and DEX groups were compared. RESULTS Twenty-eight patients (18 boys and 10 girls; mean age 5.5 years) were treated with systemic corticosteroids. Twelve of the 22 courses of PSL and 33 of the 44 courses of DEX were found to be associated with high IOP. The maximal IOP was higher with the use of DEX than with the use of PSL, including in those who received prophylactic therapy (PSL 25.2 mmHg, DEX 33.6 mmHg; P = 0.02). Antiglaucoma medication was given to 21 patients; 6 patients had symptoms of ocular hypertension. The maximal IOPs were 52.8 mmHg and 70.8 mmHg in the PSL and DEX groups, respectively. Both groups of patients reported severe headache. CONCLUSION Increased IOP was frequently observed during systemic corticosteroid therapy in pediatric patients with ALL. Although most patients were asymptomatic, they occasionally presented with severe systemic symptoms. Regular ophthalmologic examinations should be included in the treatment guidelines for ALL.

Abstract
Alveolar echinococcosis in slaughtered horses remains a public health issue. This study aimed to develop a Recombinase polymerase amplification (RPA) assay targeting the mitochondrial NADH dehydrogenase subunit 5 (Nad5) gene of Echinococcus multilocularis for the rapid detection of equine alveolar echinococcosis. Thirty-six hepatic solid nodules obtained from each horse (n = 36) were evaluated based on histopathological examination and Nad5-targeted PCR and then submitted to the RPA assay. The results of the developed RPA assay were 94.4% consistent with those of Nad5 PCR and Cohen's kappa coefficient value was 0.89 statistically, indicating high agreement. In addition, the RPA assay using the plasmid samples was one hundredfold more sensitive than PCR testing. Consequently, these results suggest that the performance of the RPA assay developed in this study is equal to that of conventional PCR testing.

Abstract
Safer and more effective cow milk (CM)-oral immunotherapy that does not induce allergic reactions has not yet been standardised. We sought to explore the efficacy and feasibility of a combination of heat-killed Lactiplantibacillus plantarum YIT 0132 (LP0132) and oral immunotherapy for treating IgE-mediated cow milk allergy (CMA). We conducted a 24-week, double-blind, randomised (1:1), two-arm, parallel-group, placebo-controlled, phase 2 trial of LP0132 intervention for treating IgE-mediated CMA in children aged 1-18 years (n=60) from January 29, 2018 to July 12, 2019 in Tokyo, Japan. Participants were randomly assigned to the LP0132 group receiving citrus juice fermented with LP0132 or to the control group receiving citrus juice without. Both groups received low-dose slow oral immunotherapy with CM. The primary outcome was improved tolerance to CM, proven by the CM challenge test at 24 weeks. Secondary outcomes were changes in serum biomarkers of serum-specific β-lactoglobulin-IgE (sIgE) and β-lactoglobulin-IgG4 (sIgG4). Exploratory outcomes included changes in serum cytokine levels and gut microbiota composition. A total of 61 participants were included. Finally, 31 children were assigned to the LP0132 group and 30 to the control group, respectively. After the intervention, 41.4 and 37.9% of the participants in the LP0132 and control groups, respectively, showed improved tolerance to CM. In serum biomarkers after the intervention, the sIgG4 level was significantly higher, and interleukin (IL)-5 and IL-9 were significantly lower, in the LP0132 group than in the control group. In the gut microbiome, the α-diversity and Lachnospiraceae increased significantly in the LP0132 group, and Lachnospiraceae after the intervention was significantly higher in the LP0132 group than in the control group. In conclusion, low-dose oral immunotherapy with modulating gut microbiota might be a safer and more effective approach for treating cow's milk allergy.

Abstract
BACKGROUND Survival is a key metric of the effectiveness of a health system in managing cancer. We set out to provide a comprehensive examination of worldwide variation and trends in survival from brain tumors in adults, by histology. METHODS We analyzed individual data for adults (15-99 years) diagnosed with a brain tumor (ICD-O-3 topography code C71) during 2000-2014, regardless of tumor behavior. Data underwent a 3-phase quality control as part of CONCORD-3. We estimated net survival for 11 histology groups, using the unbiased nonparametric Pohar Perme estimator. RESULTS The study included 556,237 adults. In 2010-2014, the global range in age-standardized 5-year net survival for the most common sub-types was broad: in the range 20%-38% for diffuse and anaplastic astrocytoma, from 4% to 17% for glioblastoma, and between 32% and 69% for oligodendroglioma. For patients with glioblastoma, the largest gains in survival occurred between 2000-2004 and 2005-2009. These improvements were more noticeable among adults diagnosed aged 40-70 years than among younger adults. CONCLUSIONS To the best of our knowledge, this study provides the largest account to date of global trends in population-based survival for brain tumors by histology in adults. We have highlighted remarkable gains in 5-year survival from glioblastoma since 2005, providing large-scale empirical evidence on the uptake of chemoradiation at population level. Worldwide, survival improvements have been extensive, but some countries still lag behind. Our findings may help clinicians involved in national and international tumor pathway boards to promote initiatives aimed at more extensive implementation of clinical guidelines.

Abstract
A well-known feature of a propagating localized excitation in a discrete lattice is the generation of a backwave in the extended normal mode spectrum. To quantify the parameter-dependent amplitude of such a backwave, the properties of a running intrinsic localized mode (ILM) in electric, cyclic, dissipative, nonlinear 1D transmission lines, containing balanced nonlinear capacitive and inductive terms, are studied via simulations. Both balanced and unbalanced damping and driving conditions are treated. The introduction of a unit cell duplex driver, with a voltage source driving the nonlinear capacitor and a synchronized current source, the nonlinear inductor, provides an opportunity to design a cyclic, dissipative self-dual nonlinear transmission line. When the self-dual conditions are satisfied, the dynamical voltage and current equations of motion within a cell become the same, the strength of the fundamental, resonant coupling between the ILM and the lattice modes collapses, and the associated fundamental backwave is no longer observed.

Abstract
Samples of the carbonaceous asteroid Ryugu were brought to Earth by the Hayabusa2 spacecraft. We analyzed 17 Ryugu samples measuring 1 to 8 millimeters. Carbon dioxide-bearing water inclusions are present within a pyrrhotite crystal, indicating that Ryugu's parent asteroid formed in the outer Solar System. The samples contain low abundances of materials that formed at high temperatures, such as chondrules and calcium- and aluminum-rich inclusions. The samples are rich in phyllosilicates and carbonates, which formed through aqueous alteration reactions at low temperature, high pH, and water/rock ratios of <1 (by mass). Less altered fragments contain olivine, pyroxene, amorphous silicates, calcite, and phosphide. Numerical simulations, based on the mineralogical and physical properties of the samples, indicate that Ryugu's parent body formed ~2 million years after the beginning of Solar System formation.

Abstract
Nonsense-mediated messenger RNA (mRNA) decay (NMD) has been intensively studied as a surveillance pathway that degrades erroneous transcripts arising from mutations or RNA processing errors. While additional roles in physiological control of mRNA stability have emerged, possible functions in mammalian physiology in vivo remain unclear. Here, we created a conditional mouse allele that allows converting the NMD effector nuclease SMG6 from wild-type to nuclease domain-mutant protein. We find that NMD down-regulation affects the function of the circadian clock, a system known to require rapid mRNA turnover. Specifically, we uncover strong lengthening of free-running circadian periods for liver and fibroblast clocks and direct NMD regulation of Cry2 mRNA, encoding a key transcriptional repressor within the rhythm-generating feedback loop. Transcriptome-wide changes in daily mRNA accumulation patterns in the entrained liver, as well as an altered response to food entrainment, expand the known scope of NMD regulation in mammalian gene expression and physiology.

Abstract
BACKGROUND The prevalence of myopia keeps increasing during the COVID-19 pandemic. We aimed to map the worldwide treatment preferences of ophthalmologists managing myopia control during the first wave of the pandemic. METHODS An online questionnaire inquiring about pharmacological and optical treatment patterns during the first half of 2020 was sent to pediatric ophthalmology as well as general ophthalmology memberships worldwide. The results among pediatric ophthalmologists were compared to a previous study we performed before the pandemic. RESULTS A total of 2269 respondents from 94 countries were included. Most respondents were pediatric ophthalmologists (64.6%), followed by ophthalmologists from other subspecialties (32.3%). The preferred modality for all geographical regions was a combination therapy of pharmacological and optical treatments. When evaluated independently, the pharmacological treatment was more popular than the optical treatment in most regions other than East Asia (P < 0.001). Compared to a pre-pandemic questionnaire, the participation of pediatric ophthalmologists affiliated with non-university hospitals increased. Additionally, the prevalence of respondents utilizing either any type of pharmacological treatment and those that using only evidence-based treatments increased globally. Although a decline in the use of optical treatment was evident worldwide, the use of evidence-based optical treatments increased. CONCLUSION Ophthalmologists around the world preferred a combination therapy of pharmacological and optical treatments. More pediatric ophthalmologists treated myopia progression and preferred a better evidence-based approach to control myopia. These trends reflect a positive response and more awareness of the rising prevalence of myopia due to the increased burden of myopia imposed by the COVID-19 pandemic.

Abstract
BACKGROUND The Fundamental Use of Surgical Energy (FUSE) program was established to educate surgeons and trainees to promote awareness and behaviors for the safe use of surgical energy devices. Despite its implementation, the impact of FUSE certification on surgeons' behavior and safety awareness regarding practice of energy devices remains unclear. This study aimed to identify the perceived impact of FUSE certification on surgeons' behavior and awareness regarding the safe use of surgical energy devices. METHODS We performed a descriptive cross-sectional survey study, using non probabilistic purposive sampling, and distributed 22-item web-based questionnaires among all 59 FUSE-certified surgeons in Japan, excluding operating room nurses and medical students. The questionnaire items covered demographics, surgical techniques using various energy devices, changes in behavior and safety awareness, communication with colleagues about surgical energy devices, and educational activities related to energy devices. RESULTS Fifty-seven participants completed the questionnaire (response rate 96.6%). Most surgeons (91.3%) could apply material learned from the FUSE program in practice, especially material related to monopolar electrosurgery. Fifty-six surgeons (98.3%) reported increased awareness of surgical safety, and 35 (61.5%) reported increased communication with operating room personnel about the safe use of energy devices. Moreover, 56 participants (98.3%) indicated a need for systematic education in surgical energy, with participants recommending fellows (94.7% of participants specified that fellows should participate in further education), residents (75.4%), and attending surgeons (63.2%) as the target recipients of this training. Conclusions After FUSE certification, not only did surgeons' knowledge increase, but their energy-related surgical techniques in practice also improved. Furthermore, FUSE-certified surgeons felt that they were more aware of surgical-energy safety and were dedicated to its promotion.

Abstract
INTRODUCTION The Non-Invasive Prenatal Testing (NIPT) guideline was issued and applied in 2013 by the Japanese Medical Association. Since being issued, the NIPT practice in Japan still has some problems related to indication, access, cost coverage and uniformity. Therefore, our study aimed to identify the Japanese challenges of adopting NIPT into prenatal diagnosis by comparing the system and process with other countries. METHOD The United Kingdom, Germany, Italy, Sweden, and Taiwan were purposefully selected for comparison. All the countries, including Japan, introduced NIPT. The literature and information searches were conducted using PubMed, SCOPUS, Google Scholar, CiNii and Google searching engine. RESULTS The process of NIPT in Japan was very different from the other countries. Japan is the only country that indicated NIPT for only pregnant women over 35 years old in certificated facilities and did not have a policy regarding providing information on prenatal screening and NIPT to all women. Japan also did not have a policy regarding abortion due to fetal abnormalities. The practice of NIPT guidelines is different between non-certified and certified facilities. NIPT fee was the highest in Japan and was not covered by insurance. CONCLUSION Pregnant women in Japan suffered from disparities in information access, economic burden, geographic location, and practice of NIPT guidelines between the certified and the non-certified facilities. Pregnant women-centered prenatal diagnosis policy, including NIPT, should be established in Japan by learning cases from other countries.

Abstract
Deep angiomyxoma is a rare, infiltrative, hormone-dependent, benign-mesenchymal neoplasm that occurs in the deep soft tissues of the perineal regions. In total, 33% females with newly diagnosed deep angiomyxoma will typically relapse within 5 years after the standard treatment of radical resection. Postoperative hormone therapy is frequently administered to prevent recurrence, but the role of prophylactic oophorectomy in premenopausal women remain to be fully elucidated. In the present report, a 42-year-old Japanese woman was referred for a refractory Bartholin's cyst that is 14 cm in diameter. Based on the results of imaging (unenhanced CT and MRI) and histopathology, deep angiomyxoma was suspected, but no definitive diagnosis was possible. Tumor resection and bilateral salpingo-oophorectomy were performed before the postoperative diagnosis was confirmed to be deep angiomyxoma. The patient received an aromatase inhibitor (2.5 mg letrozole daily) as adjuvant hormonal therapy. There was no evidence of recurrence at the 1-year postoperative follow-up. In conclusion, prophylactic oophorectomy and postoperative adjuvant therapy with aromatase inhibitors may be a promising treatment option for deep angiomyxoma to optimize the outcome of surgical treatment. Long-term follow-up is required to monitor for the late and/or local recurrence of deep angiomyxoma and possible adverse effects of adjuvant hormonal therapy.

Abstract
AIM Work performance of nurses is a critical aspect that concerns the safety of both nurses and patients, but also secondarily influences nurses' turnover due to serious fatigue and burnout. Monitoring nursing performance as well as fatigue is important for appropriate safety management of patients and nurses, and the development of a monitoring tool is essential. The Nursing Performance Instrument (NPI) can provide comprehensive and brief monitoring of nursing performance. This study aimed to verify the validity and reliability of a Japanese version of the NPI (NPI-J). METHODS A cross-sectional study was conducted on nurses who work in inpatient care across five Japanese hospitals. We considered appropriate factor numbers with parallel analysis and the Velicer's minimum average partial test. The construct validity was evaluated using exploratory factor analysis, confirmatory factor analysis (CFA), and Pearson's correlation analysis. Cronbach's alpha was calculated for the internal consistency. RESULTS A three-factor model eventually showed acceptable fit indices in the CFA. Moreover, the correlation results among the three factors indicated discriminant validity comparable to the original NPI. The correlation results with acute fatigue, chronic fatigue, and burnout verified convergent validity. Internal consistency was insufficient. CONCLUSION The NPI-J demonstrated acceptable construct validity. This instrument can assess nurses' perceptions of their performance by measuring each item. Future work on the reliability of the sub-concepts will require additional items or reliability testing based on generalizability theory and item response theory.

Abstract
PURPOSE To evaluate intraocular pressure (IOP) at different gaze positions in patients with highly myopic strabismus (HMS). STUDY DESIGN Nonrandomized, prospective, observational study. METHODS This study included 18 eyes of 14 patients with HMS and 51 eyes of 51 age-matched controls without strabismus; these were further divided into two groups based on refractive errors: > -6.00 diopter (D) (n = 22 eyes) and ≤ -6.00 D (n = 29 eyes). IOP was measured in primary and side gazes and compared within and among groups. The relationships between IOPs and axial length, angle of globe dislocation measured on magnetic resonance imaging, strabismus angle, and degree of abduction deficit were studied. RESULTS The HMS group showed higher IOP in abduction (19.3 ± 4.9 mmHg) than in the primary (12.5 ± 4.3 mmHg) and adducting positions (13.0 ± 3.3 mmHg), (p < 0.001). The IOP in the adducting position in the HMS group (13.0 ± 3.3 mmHg) was lower than in the control groups both with (17.6 ± 3.5 mmHg) and without (16.9 ± 4.1 mmHg) high myopia, ; (p < 0.001 and = 0.003). The difference in IOP between abduction and adduction was significantly larger in the HMS group (6.4 ± 4.6 mmHg) compared to others (p < 0.001) and positively correlated with the strabismus angle and the angle of globe dislocation and negatively with abduction deficit. CONCLUSION The IOP of patients with HMS changes dramatically on side gazes, therefore, care should be taken while measuring IOP.

Abstract
The cyanobacterium Anabaena sp. strain PCC 7120 exhibits dehydration tolerance. The regulation of gene expression in response to dehydration is crucial for the acquisition of dehydration tolerance, but the molecular mechanisms underlying dehydration responses remain unknown. In this study, the functions of the response regulator OrrA in the regulation of salt and dehydration responses were investigated. Disruption of orrA abolished or diminished the induction of hundreds of genes in response to salt stress and dehydration. Thus, OrrA is a principal regulator of both stress responses. In particular, OrrA plays a crucial role in dehydration tolerance because an orrA disruptant completely lost the ability to regrow after dehydration. Moreover, in the OrrA regulon, avaKa encoding a protein of unknown function was revealed to be indispensable for dehydration tolerance. OrrA and AvaK are conserved among the terrestrial cyanobacteria, suggesting their conserved functions in dehydration tolerance in cyanobacteria.

Abstract
BACKGROUND Physical inactivity is one of the major risk factors for non-communicable diseases. Few studies about physical activity have been conducted among refugees from neighbouring countries. Given changes in the situation of Syrians, assessment of physical activity among Syrian refugees is required to understand their situation. This study aimed to evaluate the degree of self-reported physical activity and to identify perceived facilitators of and barriers to physical activity among Syrian refugees living in Amman, Jordan, in 2017. METHODS This community-based cross-sectional study was conducted using a structured questionnaire and the short form of the International Physical Activity Questionnaire. Participants were eligible for the study if they were Syrian refugees aged 18-64 years, living in Amman city, and were either registered with the United Nations High Commissioner for Refugees, waiting for their registration, or had a service card issued by the Jordanian Ministry of Interior. The relationship between physical activity level and sex was assessed using the chi-square test and Cochran-Armitage tests. The Mann-Whitney U test was performed to assess the relationship between the median metabolic equivalent scores of physical activity and gender. Backward stepwise logistic regression analysis was used to analyse the association between predictors of physical inactivity and physical activity level. RESULTS Among the 173 participants, the majority (91.9%) reported moderate to a high level of physical activity, and 8.1% were physically inactive. The metabolic equivalent scores for the walking activity of males (median: 1039.5, IQR: 0, 2772) was significantly higher than that of females (median: 396, IQR: 0, 1188) (p < 0.01). "Perceived change in the amount of physical activity" was a significant predictor of physical inactivity (adjusted OR = 3.00; 95%CI: 1.27-7.26). Common facilitators of physical activity were "psychological wellbeing"(49.7%) and "prevent diseases"(46.8%). The greatest barriers to physical activity were "time limitation"(43.4%) and "high cost"(57.8%). CONCLUSION This study revealed the physical activity level among Syrian refugees in Amman. The perceived facilitators and barriers to physical activity identified among Syrian refugees were similar to those in previous studies conducted among non-refugees. These results provide a valuable baseline for future examinations of physical activity level and to verify its possible facilitators and barriers.

Abstract
Deficiency of a soluble form of the advanced glycation end products receptor (sRAGE) is implicated in obesity-induced complications. Serum sRAGE is inclined to be modified by changes in body weight. We analysed serum sRAGE concentrations in patients with obesity undergoing moderate calorie restriction, which mimics the real-life situation and is not harmful to obese humans. Serum sRAGE was measured by immunoassay in 50 patients with obesity who underwent calorie restriction by 300-500 kcal/day for 8 weeks. In effect calorie restriction resulted in an expected decrease in body weight (by 2.1 kg for an 8-week intervention, p<0.0001), as well as reduced systolic blood pressure, modified dyslipidemia (cholesterol, triglycerides), reduced obesity-related inflammation (tumor necrosis factor-alfa, interleukin-6, C-reactive protein), improved insulin sensitivity. However, it was not accompanied by any significant change in sRAGE concentration. There was a strong negative correlation between BMI and the sRAGE level. Accordingly, the levels of sRAGE were the highest in lean control. In conclusion: a modest weight reduction is unlikely to improve decreased sRAGE levels.

Abstract
PURPOSE To compare conjunctival-scleral thickness measured with anterior segment optical coherence tomography before and after medial rectus muscle resection and plication for exotropia. METHODS In this prospective observational study, patients with exotropia aged 5 years and older who underwent medial rectus muscle resection or plication through limbal incision of the conjunctiva between April 2016 and June 2018 were enrolled. Conjunctivalscleral thickness was measured with anterior segment optical coherence tomography before and 3 and 6 months after surgery at 1.5 mm (limbus), 4 mm (insertion), and 5.5 mm (tendon) posterior to the scleral spur. One examiner made measurements twice blinded for the initial data. Conjunctival-scleral thickness was compared between groups using the Mann-Whitney U test. RESULTS Twenty participants were divided into two groups: resection (n = 11) and plication (n = 9). The respective conjunctival-scleral thicknesses before and 3 and 6 months after surgery in the resection group were as follows: 0.76, 0.90, and 0.86 mm at the limbus; 0.86, 1.18, and 1.12 mm at the insertion; and 1.04, 1.41, and 1.33 mm at the tendon. Corresponding values in the plication group were as follows: 0.74, 0.87, and 0.81 mm at the limbus; 0.84, 1.16, and 1.08 mm at the insertion; and 1.00, 1.39, and 1.27 mm at the tendon. No between-group differences were observed at any location or time. CONCLUSIONS No differences in conjunctival-scleral thickness were observed between the resection and plication groups before surgery or at 3 months and 6 months postoperatively.

Abstract
Under the International Atomic Energy Agency (IAEA) Modelling and Data for Radiological Impact Assessments (MODARIA II) Programme, Working Group 4 activities included collating radionuclide transfer data from Japan following the Fukushima Daiichi Nuclear Power Plant accident and separately collating concentration ratio (CR) data for root uptake of radionuclides by crops grown in tropical and arid climates. In this paper, the newly compiled radiocaesium CR data for fruit from Japan, tropical and arid climates have been combined with the data originally compiled for the IAEA Technical Reports Series No. 472 (TRS 472) and additional data identified from the literature to produce an enhanced MODARIA II dataset of fruit radiocaesium CR values. Statistical analysis of the MODARIA II dataset by climate class (based on the Köppen-Geiger climate classification) indicated that the CR values for tropical climates were significantly higher (p< 0.05) than those for arid, temperate and cold climates. Statistical analysis of the MODARIA II dataset by soil group (based on soil texture) indicated that the CR values for coral sand soil (tropical climates only) and organic soil (temperate climates only) were significantly higher (p< 0.05) than those for the clay, loam and sand soil groups. Statistical analysis of the MODARIA II dataset by plant group (based on plant morphology) indicated that the CR values for non-woody trees (tropical climate bias) were significantly higher (p< 0.05) than those for herbaceous plants, shrubs and woody trees. Comparison of the MODARIA II dataset with original TRS 472 values showed only small changes in the fruit radiocaesium CR values for herbaceous plants and shrubs in temperate climates. There was a decrease in the CR values for woody trees in temperate climate across all soil groups. There was also a decrease in the CR values for tropical climates for all comparable soil groups.

Abstract
Objectives Shift‐work nurses are at a higher risk of inadequate recovery from fatigue and developing maladaptive fatigue with significant health consequences. Therefore, it is necessary to monitor fatigue and recovery levels with a reliable scale. We investigated psychometric properties of the Japanese version of the Occupational Fatigue Exhaustion Recovery scale (OFER‐J) for shift‐work nurses. Methods Japanese shift‐work nurses responded to self‐administered questionnaires at baseline (n = 942) and one month later (n = 334). The confirmatory factor analysis (CFA) and exploratory factor analysis (EFA) were conducted to verify the structural validity and the correlation analysis and one‐way analysis of variance were conducted to test the construct and discriminative validity. Cronbach's alpha coefficient, intra‐class correlation coefficient (ICC), and smallest detectable change (SDC) were calculated to assess reliability. Results The CFA showed high correlations between the factors and whilst the goodness‐of‐fit of the three‐factor model was suboptimal, it was in an acceptable range. Most modifications included the error covariance of the Acute Fatigue (AF) and Intershift Recovery (IR) items. The EFA showed that Chronic Fatigue (CF) and AF were not clearly separated, indicating that the two AF items dropped out. Construct and discriminative validity were also well indicated. Cronbach's alpha coefficients were 0.75–0.85. Only CF showed sufficient reproductivity (ICC = 0.74). The SDC for CF, AF, and IR was 14.0, 17.1, and 18.7, respectively. Conclusions The validity and reliability of the OFER‐J were verified as acceptable for shift‐work nurses. The OFER‐J could contribute to a data‐based approach to fatigue management in nursing management practice.

Abstract
PURPOSE Chronic progressive external ophthalmoplegia (CPEO) is a mitochondrial disease characterized by slowly progressive ptosis and limitations in ocular motility. Although exophthalmos is not considered to be a common feature of CPEO, this study focused on the incidence of exophthalmos in patients with CPEO. STUDY DESIGN Retrospective observational case series METHODS: We reviewed the clinical charts of patients who received a diagnosis of CPEO sometime during the period between January 2010 and December 2018. CPEO was diagnosed on the basis of detection of a deletion of mitochondrial DNA (mtDNA) from saliva, buccal mucosa, or extraocular muscle specimens obtained during strabismus surgery. Horizontal MRI/CT images or Hertel ophthalmometry was used in determining exophthalmos. RESULTS Seven patients (4 males) were identified. The mean age at diagnosis was 32.6 years (range 13-53 years). mtDNA deletion mutations were detected in the buccal mucous membrane DNA in 5 patients and in the saliva and extraocular muscle DNA in 2 patients. MRI/CT was recorded in 6 patients, four of whom showed exophthalmos (cases 1-4), and case 5 was determined as exophthalmos on the basis of a Hertel ophthalmometer reading. Exophthalmos was bilateral in 4 of the patients (cases 1, 2, 4, and 5) and unilateral in 1 patient (case 3). Exophthalmos was the chief concern of 2 of the patients; however, it was not clinically significant in the other patients. CONCLUSIONS Although exophthalmos may not be recognized by either the patient or the clinician, it may be one of the common features of CPEO. A large multiethnic study should be performed.

Abstract
Mistimed exposure to light has been demonstrated to negatively affect multiple aspects of physiology and behavior. Here we analyzed the effects of chronic exposure to abnormal lighting conditions in mice. We exposed mice for 1 year to either: a standard light/dark cycle, a “light-pollution” condition in which low levels of light were present in the dark phase of the circadian cycle (dim light at night, DLAN), or altered light cycles in which the length of the weekday and weekend light phase differed by 6 h (“social jetlag”). Mice exhibited several circadian activity phenotypes, as well as changes in motor function, associated particularly with the DLAN condition. Our data suggest that these phenotypes might be due to changes outside the core clock. Dendritic spine changes in other brain regions raise the possibility that these phenotypes are mediated by changes in neuronal coordination outside of the clock. Given the prevalence of artificial light exposure in the modern world, further work is required to establish whether these negative effects are observed in humans as well.

Abstract
OBJECTIVE The maximum phonation time (MPT) is used to assess simple respiratory functions and can be performed anywhere without special instruments. We investigated the association between MPT and respiration, considering the future utilization of simple respiratory assessments during home-based physical therapy. METHOD This cross-sectional study included 140 older adults enrolled in Japanese long-term care insurance (77 men, 63 women; mean age, 77.9±8.0 years). The participants performed the MPT, followed by spirometry. We analyzed the MPT of the three age groups, relative reliability of the MPT values, and the association between MPT and respiratory function. RESULTS We found that the MPT of older men requiring long-term care or support was related to age. The intraclass correlation coefficient of MPT was >0.8 for all groups. Only forced vital capacity was associated with MPT in the partial correlation and multiple regression analyses. CONCLUSION MPT could be an alternative assessment of respiratory function in home-based physical therapy for older adults requiring long-term care or support.

Abstract
Kyphomelic dysplasia is a heterogeneous group of skeletal dysplasias characterized by severe bowing of the limbs associated with other variable findings, such as narrow thorax and abnormal facies. We searched for the genetic etiology of this disorder. Four individuals diagnosed with kyphomelic dysplasia were enrolled. We performed whole-exome sequencing and evaluated the pathogenicity of the identified variants. All individuals had de novo heterozygous variants in KIF5B encoding kinesin-1 heavy chain: two with c.272A>G:p.(Lys91Arg), one with c.584C>A:p.(Thr195Lys), and the other with c.701G>T:p.(Gly234Val). All variants involved conserved amino acids in or close to the ATPase activity-related motifs in the catalytic motor domain of the KIF5B protein. All individuals had sharp angulation of the femora and humeri, distinctive facial features, and neonatal respiratory distress. Short stature was observed in three individuals. Three developed postnatal osteoporosis with subsequent fractures, two showed brachycephaly, and two were diagnosed with optic atrophy. Our findings suggest that heterozygous KIF5B deleterious variants cause a specific form of kyphomelic dysplasia. Furthermore, alterations in kinesins cause various symptoms known as kinesinopathies, and our findings also extend the phenotypic spectrum of kinesinopathies. This article is protected by copyright.

Abstract
We have measured the 3d→2p transition x rays of kaonic ^{3}He and ^{4}He atoms using superconducting transition-edge-sensor microcalorimeters with an energy resolution better than 6 eV (FWHM). We determined the energies to be 6224.5±0.4(stat)±0.2(syst) eV and 6463.7±0.3(stat)±0.1(syst) eV, and widths to be 2.5±1.0(stat)±0.4(syst) eV and 1.0±0.6(stat)±0.3(stat) eV, for kaonic ^{3}He and ^{4}He, respectively. These values are nearly 10 times more precise than in previous measurements. Our results exclude the large strong-interaction shifts and widths that are suggested by a coupled-channel approach and agree with calculations based on optical-potential models.

Abstract
In this experimental study of the nonlinear loss mechanism between traveling localized excitation and the underlying extended normal mode spectrum for a 1D lattice, three types of cyclic, electric, nonlinear transmission lines (NLTLs) are used. They are nonlinear capacitive, inductive, and capacitive+inductive NLTLs. To maintain a robust, steady-state traveling intrinsic localized mode (ILM), a traveling wave driver is used. The ILM loses energy because of a resonance between it and the extended NLTL modes. A wake field excitation is detected directly from ILM velocity experiments by the decrease in ILM speed and by the observation of the wake. Its properties are quantified via a two-dimensional Fourier map in the frequency-wavenumber domain, determined from the measured spatial-time voltage pattern. Simulations support and extend these experimental findings. We find for the capacitive+inductive NLTL configuration, when the two nonlinear terms are theoretically balanced, the wake excitation is calculated to become very small, giving rise to supertransmission over an extended driving frequency range.

Abstract
Purpose: Uniparental disomy (UPD) is a rare chromosomal abnormality. We performed whole-exosome sequencing (WES) in cases of early-onset retinal dystrophy and identified two cases likely caused by UPD. Herein, we report these two cases and attempt to clarify the clinical picture of retinal dystrophies caused by UPD. Methods: WES analysis was performed for two patients and their parents, who were not consanguineous. Functional analysis was performed in cases suspected of congenital disorders of glycosylation (CDG). We obtained clinical case data and reviewed the literature. Results: In case 1, a novel c.57G>C, p.(Trp19Cys) variant in SRD5A3 was detected homozygously. Genetic analysis suggested a maternal UPD on chromosome 4, and functional analysis confirmed CDG. Clinical findings showed early-onset retinal dystrophy, intellectual disability, and epilepsy. In case 2, an Alu insertion (c.4052_4053ins328, p.[Tyr1352Alafs]) in RP1 was detected homozygously. Maternal UPD on chromosome 8 was suspected. The clinical picture was consistent with RP1-related retinitis pigmentosa. Although the clinical features of retinal dystrophy by UPD may vary, most cases present with childhood onset. Conclusions: There have been limited reports of retinal dystrophy caused by UPD, suggesting that it is rare. Genetic counseling may be encouraged in pediatric cases of retinal dystrophy.

Abstract
Accurate assessment of renal function is essential for determining serum vancomycin (VCM) concentration. Creatinine clearance (Ccr)-calculated using the Cockcroft and Gault (CG) equation-can be used to evaluate renal function for determining VCM dosage. However, Ccr-based evaluation may not be an accurate representation of the renal function in the elderly. Herein, we examine the effectiveness of estimated glomerular filtration rate (eGFR) calculated using the Berlin Initiative Study-1 (BIS1) equation, for predicting the serum VCM concentration. Herein, we retrospectively analyzed patients (aged ≥ 75 years) who had received VCM. Serum VCM concentration was predicted based on Ccr and eGFR. eGFR was calculated using the Japanese equation for eGFR (eGFRJAP), Modification of Diet in Renal Disease (MDRD) equation (eGFRMDRD), chronic kidney disease epidemiology collaboration (CKD-EPI) equation (eGFRCKD-EPI), and BIS1 equation (eGFRBIS1). The predicted serum VCM concentration was compared with the measured values. Prediction bias, accuracy, and precision were evaluated by calculating the mean prediction error (ME), mean absolute prediction error (MAE), and root mean squared prediction error (RMSE). Our results showed that the ME between the measured and the predicted values calculated using Ccr and each eGFR was the largest and smallest when calculated based on Ccr and eGFRMDRD, respectively. MAE and RMSE were the largest and smallest when calculated based on Ccr and eGFRBIS1, respectively. A significant difference was observed in the MAE associated with eGFRJAP, eGFRMDRD, and eGFRCKD-EPI compared to that associated with eGFRBIS1. In conclusion, our results suggest that the BIS1 equation might be useful for determining the VCM dosage in the elderly.

Abstract
OBJECTIVES The study aimed to assess the determinants of modern contraceptive method use among young women in Benin. DESIGN A mixed-methods design. SETTING AND PARTICIPANTS We used the Benin 2017-2018 Demographic and Health Survey datasets for quantitative analysis. Data collection was conducted using multiple-cluster sampling method and through household survey. Qualitative part was conducted in the city of Allada, one of the Fon cultural capitals in Benin. The participants were purposively selected. OUTCOMES Contraceptive prevalence rate, unmet need for modern method and percentage of demand satisfied by a modern method for currently married and sexually active unmarried women were measured in the quantitative part. Access barriers and utilisation of modern methods were assessed in the qualitative part. RESULTS Overall, 8.5% (95% CI 7.7% to 9.5%) among young women ages 15-24 were using modern contraceptives and 13% (12.1% to 14.0%) among women ages 25 or more. Women 15-24 had a higher unmet need, and a lower demand satisfied by modern contraceptive methods compared with women ages 25 or more. 60.8% (56.9% to 64.7%) of all unmarried young women had unmet need for modern contraceptives. Young women were more likely to use male condoms which they obtain mainly from for-profit outlets, pharmacies and relatives. The factors associated with demand satisfied by a modern method were literacy, being unmarried, knowing a greater number of modern contraceptive methods and experiencing barriers in access to health services. On the other hand, the qualitative study found that barriers to using modern methods include community norms about pre-marital sexual intercourse, perceptions about young women's fertility, spousal consent and the use of non-modern contraceptives. CONCLUSION Contraceptive use is low among young women in Benin. The use of modern contraceptives is influenced by sociodemographic factors and social norms. Appropriate interventions might promote comprehensive sexuality education, increase community engagement, provide youth-friendly services and address gender inequalities.
