Abstract
BACKGROUND Concomitant resection of the sciatic nerve along with a malignant tumor is no longer a contraindication for limb-sparing surgery, as most of these patients remain ambulatory. However, sciatic nerve reconstruction after sarcoma resection is not commonly performed. Restoration of nerve function can improve patient quality of life. We describe our experience with four patients who underwent sciatic nerve reconstruction using an ipsilateral common peroneal nerve graft at the time of sarcoma resection. METHODS Because of the low chance of peroneal nerve recovery, the ipsilateral peroneal trunk was used as a graft to reconstruct the tibial trunk of the sciatic nerve. Two patients were men and two were women. Mean age was 45.3 years (range, 15-62). Mean sciatic nerve defect length was 9.4 cm (range, 8.5-12.0). Proximal thigh defects (three patients) were reconstructed with a double cable; the one patient with a distal thigh defect underwent single cable reconstruction. Mean operation time was 492 min (range, 428-682). RESULTS Mean length of the harvested peroneal trunks was 21 cm (range, 11-26). Mean graft length was 11.9 cm (range, 11-13). Postoperative course was uneventful in all four patients. One patient died of sarcoma lung metastasis and could not be evaluated. Three patients were followed for more than 2 years. Two patients achieved British Medical Research Council grade 4 plantar flexion; the remaining patient achieved grade 5 plantar flexion and grade 4 toe flexion. Semmes-Weinstein monofilament sensory testing showed loss of protective sensation on the plantar surface in all three. Musculoskeletal Tumor Society scores at last follow-up were 60.0%, 70.0%, and 43.3%, respectively. CONCLUSIONS Immediate sciatic nerve reconstruction using an ipsilateral common peroneal nerve graft avoids reconstruction delay and scar tissue formation, which is advantageous for nerve recovery. This technique may be considered when sciatic nerve resection is anticipated during sarcoma resection.

Abstract
Solution-state nuclear magnetic resonance spectroscopy (NMR) is a powerful method for the analysis of intermolecular interactions within a biomolecular system. However, low sensitivity is one of the major obstacles of NMR. We improved the sensitivity of solution-state 13C NMR for the observation of intermolecular interactions between protein and ligand using hyperpolarized solution samples at room temperature. Eutectic crystals composed of 13C-salicylic acid and benzoic acid doped with pentacene were hyperpolarized by dynamic nuclear polarization using photoexcited triplet electrons, and a 13C nuclear polarization of 0.72 ± 0.07% was achieved after dissolution. The binding of human serum albumin and 13C-salicylate was observed with several hundred times sensitivity enhancement under mild conditions. The established 13C NMR was applied for pharmaceutical NMR experiments by observation of the partial return of the 13C chemical shift of salicylate by competitive binding with other non-isotope-labeled drugs.

Abstract
This study investigated the long-term survival and incidence of secondary fractures after fragility hip fractures. The 5-year survival rate was 62%, and the mortality risk was seen in patients with GNRI < 92. The 5-year incidence of secondary fracture was 22%, which was significantly higher in patients with a BMI < 20. BACKGROUND Malnutrition negatively influences the postoperative survival of patients with fragility hip fractures (FHFs); however, little is known about their association over the long term. OBJECTIVE This study evaluated the ability of the geriatric nutritional risk index (GNRI) as a risk factor for long-term mortality after FHFs. METHODS This study included 623 Japanese patients with FHFs over the age of 60 years. We prospectively collected data on admission and during hospitalization and assessed the patients' conditions after discharge through a questionnaire. We examined the long-term mortality and the incidence of secondary FHFs and assessed the prognostic factors. RESULTS The mean observation period was 4.0 years (range 0-7 years). The average age at the time of admission was 82 years (range 60-101 years). The overall survival after FHFs (1 year, 91%; 5 years, 62%) and the incidence of secondary FHFs were high (1 year, 4%; 5 years, 22%). The multivariate Cox proportional hazard analysis revealed the risk factors for mortality as older age (hazard ratio [HR] 1.04), male sex (HR 1.96), lower GNRI score (HR 0.96), comorbidities (malignancy, HR 2.51; ischemic heart disease, HR 2.24; revised Hasegawa dementia scale ≤ 20, HR 1.64), no use of active vitamin D3 on admission (HR 0.46), and a lower Barthel index (BI) (on admission, HR 1.00; at discharge, HR 0.99). The GNRI scores were divided into four risk categories: major risk (GNRI, < 82), moderate risk (82-91), low risk (92-98), and no risk (> 98). Patients at major and moderate risks of GNRI had a significantly lower overall survival rate (p < 0.001). Lower body mass index (BMI) was also identified as a prognostic factor for secondary FHFs (HR 0.88 [p = 0.004]). CONCLUSIONS We showed that older age, male sex, a lower GNRI score, comorbidities, and a lower BI are risk factors for mortality following FHFs. GNRI is a novel and simple predictor of long-term survival after FHFs.

Abstract
OBJECTIVE Today, most individuals with cerebral palsy are adults who need a paediatric-to-adult health care transition. However, many remain in paediatric care for treatment of adult-onset health issues. Therefore, a systematic review based on the 'Triple Aim' framework was performed to determine the status of paediatric-to-adult health care transition for people with cerebral palsy. A comprehensive evaluation of transitional care was proposed for using this framework. It consists of 'experience of care', meaning satisfaction with the care, 'population health', meaning the well-being of patients, and 'cost', meaning cost-effectiveness. METHOD Electronic database (PubMed) searches were performed. The inclusion criteria were original articles published between 1990 and 2020. The search terms used in this study were ('cerebral palsy' AND 'transition to adult health care') OR ('cerebral palsy' AND 'transition'). The study type had to be epidemiological, case report, case-control, and cross-sectional, but not qualitative. The outcomes of the studies were categorised into 'care experience', 'population health', and 'cost', according to the Triple Aim framework. RESULTS Thirteen articles met the abovementioned inclusion criteria. Few studies have examined the effect of the intervention of transition for young adults with cerebral palsy. Participants in some studies had no intellectual disability. Young adults were dissatisfied with the 'care experience', 'population health', and 'cost' and had unmet health needs and inadequate social participation. INTERPRETATION Further transition intervention studies with a comprehensive assessment and proactive involvement of individuals are warranted. The presence of an intellectual disability should be considered.

Abstract
JLab E12-19-002 Experiment is planned to measure the Λ-binding energies of 3ΛH [Jπ = 1/2+ or 3/2+(T = 0)] and 4ΛH (1+) at JLab Hall C. The expected accuracy for the binding-energy measurement is |ΔBtotal Λ | ≃ 70 keV. The accurate spectroscopy for these light hypernuclei would shed light on the puzzle of the small binding energy and short lifetime of 3ΛH, and the chargesymmetry breaking in the ΛN interaction. We aim to perform the experiment in 2025.

Abstract
While it is known that the degenerated intervertebral disc (IVD) is one of the primary reasons for low-back pain and subsequent need for medical care, there are currently no established effective methods for direct treatment. Nuclear factor-κB (NF-κB) is a transcription factor that regulates various genes' expression, among which are inflammatory cytokines, in many tissues including the IVD. NF-κB decoy is an oligodeoxynucleotide containing the NF-κB binding site that entraps NF-κB subunits, resulting in suppression of NF-κB activity. In the present preclinical study, NF-κB decoy was injected into degenerated IVDs using the rabbit anular-puncture model. In terms of distribution, NF-κB decoy persisted in the IVDs up to at least 4 weeks after injection. The remaining amount of NF-κB decoy indicated that it fit a double-exponential-decay equation. Investigation of puncture-caused degeneration of IVDs showed that NF-κB decoy injection recovered, dose-dependently, the reduced disc height that was associated with reparative cell cloning and morphological changes, as assessed through histology. Gene expression, by quantitative real-time polymerase chain reaction (qRT-PCR), showed that NF-κB decoy attenuated inflammatory gene expression, such as that of interleukin-1 and tumor necrosis factor-α, in rabbit degenerated IVDs. NF-κB decoy also reduced the pain response as seen using the "pain sensor" nude rat xenograft-radiculopathy model. This is the first report demonstrating that NF-κB decoy suppresses the inflammatory response in degenerated IVDs and restores IVD disc height loss. Therefore, the intradiscal injection of NF-κB decoy may have the potential as an effective therapeutic strategy for discogenic pain associated with degenerated IVDs.

Abstract
Abstract
Background
Pulmonary hypertension (PH) is characterized by increased pulmonary vascular resistance and right heart failure with progressive narrowing or occlusion of the pulmonary artery. However, the assessment of vascular remodeling is mostly limited to averaged increases in wall thickening, and even the role of vascular endothelial growth factor (VEGF), remains incompletely understood; Although abundantly expressed VEGF is expected to elicit angio-obliteration and the knockout of hypoxia inducible factor (HIF) prevents PH in mice, VEGF inhibitor Sugen exacerbates hypoxia (Hx)-induced PH model, which is referred to as VEGF paradox.
Purpose
To analyze three-dimensional (3D) spatiotemporal changes of pulmonary microstructure and function, which reflect the disease activity and lead to resolve the paradox.
Methods and results
We developed a novel 3D visualization system of microstructural networks in whole mouse organ with single-cell resolution, using combined tissue clearing technique called CUBIC and multiphoton excitation microscope. The system enabled the simultaneous 3D evaluation of microvascular structure, invaded macrophages and fibrosis with effective penetration of several mm (whole organ). Three-dimensional observations of PH mice models including Hx, Sugen/Hx, and human-like Alk1+/− hereditary PH models, revealed that not only inward (negative) microvessel remodeling with stenosis, but also marked elongation of microvascular ECs, was evident except Sugen/Hx model at the early phase, which had not been detected by 2D histological sections. Comparable transcriptome analysis revealed that PGC1α, which regulates HIF-independent VEGF expression and angiogenesis, plays an important role in the characteristic response for mitochondrial and microvascular maintenance. PGC1α was up-regulated in the early phage in Hx and Alk1+/− PH models with microvascular angiogenetic change, whereas Sugen/Hx-model did not increase PGC1α expression and did not show microvascular remodeling. Furthermore pulmonary ECs-specific PGC1α-deficient mice exacerbated Hx-PH model with decreased VEGF expression and microvessel density, and administration of Baicalin, a flavonoid enhancing PGC1α expression, ameliorated Hx-PH model with increased VEGF expression.
Conclusions
The 3D visualization system disclosed an unexpected change of angiogenic microvascular structure in the early phage of PH, which is regulated by EC PGC1α. Microvascular angiogenesis which is induced by up-regulation in PGC1α -VEGF pathway is a crucial factor for compensation of PH in the early phase, which provides a potential novel therapeutic target for PH.

Abstract
Abstract
Background
In Japan, public health nurses provide home visitation with pregnant women who are at high risk for child maltreatment, but its effectiveness in preventing child maltreatment has not been evaluated because contents and quality of home visitation vary from municipality to municipality. This study aims to evaluate whether the tablet app developed to standardize and assist perinatal home visitation by public health nurses is effective in preventing child maltreatment.
Methods
An intervention study was conducted in 2018 in Adachi City, Tokyo, Japan. Public health nurses at two public health centers used the tablet app when they support high-risk pregnant women through home visitation and interviews, while public health nurses at the other three public health centers provided support as in the past. Because two public health centers were different in usage of the app, the treatment group was further divided into two groups: active and inactive. As fatal abuse among infants, frequency of shaking and smothering was assessed as an outcome through a self-reported questionnaire at the 4-month health check, and compared between the active treatment group, inactive treatment group, and control group, using multiple logistic regression (N = 5,651).
Results
Prevalence of infant abuse was 0.82% in the active treatment group, 1.34% in the inactive treatment group, and 1.50% in the control group. When adjusted for parental demographics and parenting situations, mothers in the active treatment group were less likely to shake or smother their baby than those in the control group (Odds ratio: 0.51, p = 0.093).
Conclusions
It possibly suggests that the tablet app developed to assist perinatal home visitation by public health nurses was effective in preventing infant abuse.
Key messages
An intervention study was conducted at public health centers in Adachi City, Tokyo, Japan, using the tablet app developed to standardize and assist perinatal home visitation by public health nurses. The finding suggested that the tablet app may be effective in preventing shaking and smothering among 4-month old infants.

Abstract
Abstract
Backgrounds
Dental caries is still a worldwide serious problem among children. Previous studies showed that higher consumption of vegetables prevents dental caries. Eating order habits, such as eating vegetables at the beginning of a meal, called “Vege-first”, may increase the amount of vegetable consumption, and in turn, prevent dental caries. We used cross-sectional data in our previous study to show the association between “Vege-first” and dental caries. However, the causal relationship of “Vege-first” on dental caries is not clear. The aim of this study to investigate the effect of “Vege-first” on dental caries, using cohort data of Japanese elementary students.
Methods
We used cohort data from 2015 to 2016 by the Adachi Child Health Impact of Living Difficulty (A-CHILD) study, a population-based study of all first- and Second- grade students in Adachi City, Tokyo, Japan. The number of DMFT (decayed, missed due to decay, and filled teeth) in 2016 was used as an outcome. Poisson regression analyses were applied to determine the independent association between keeping the “Vege-first” habit over one year and the number of DMFT in 2016 after controlling for the effects of a child's sex, parental marital status, socioeconomic status, and child's dental caries status in 2015.
Results
Of 3,164 valid participants, 45.0% had dental caries and 6.3% kept the “Vege-first” habit. Children who kept the “Vege-first” habit had fewer DMFTs in 2016 than children who did not (p < 0.001). After controlled for covariates, children with having a continuous “Vege-first” habit were still significantly and independently decreased the number of DMFT in 2016 (Incidence-rate ratios=0.87 (95% confidential interval [0.75-0.98])).
Conclusions
This study showed that having the continuous “Vege-first” habit was associated with preventive dental caries even after accounting for socioeconomic status. Health policy introducing the “Vege-first” habit may be effective to prevent pediatric dental caries.
Key messages
The practice of eating vegetables at the beginning of a meal, called “Vege-first” may increase vegetable consumption and reduce dental caries. The continuous habit of 'Vege-first' was effective in preventing a child’s dental caries even if after accounting for socioeconomic status.

Abstract
Abstract
Background
Perception of and reactive behaviors towards infant crying is one of the modifiable risk factors for postpartum depression. The aim of this study was to examine the impact of watching an educational video on infant crying within 1 week of age after delivery at maternity wards to reduce the prevalence of postpartum depressive symptoms at 1 month after giving birth.
Methods
Study design was a cluster randomized controlled trial (UMIN000015558). The intervention hospitals were randomly assigned, stratified by area and function of the hospital. Participants included 47 obstetrics hospitals or clinics out of 150 hospitals or clinics in Osaka Prefecture, Japan. In total, 44 hospitals or clinics completed the trial and 2,601 (intervention group=1,040, control group=1,561) caregivers responded to the questionnaire on postpartum depression. Mothers in the intervention group watched a 11-minute educational video, within 1 week of age, during hospitalization at maternity wards. Primary outcome in this study was postpartum depression assessed by the Edinburgh Postnatal Depression Scale as 9+, and assessed via questionnaire at a 1-month health checkup.
Results
In the intervention group, 142 (13.7%) mothers reported postpartum depression compared to 250 (16.0%) in the control group. Intention-to-treat analysis showed no significant difference in the prevalence of postpartum depression between the groups. However, among young mothers (<25 years old), the analysis showed a 67% reduction in postpartum depression (OR:0.33, 95%CI:0.15-0.72).
Conclusions
Watching an educational video on infant crying did not reduce postpartum depression at 1 month after giving birth, but it was effective for young mothers aged less than 25 years old. It may be easier to introduce our approach to any opportunity for meeting mothers during perinatal period because it does not require specialized manpower and a significant amount of time for the intervention.
Key messages
The educational video on infant crying, “Baby Doesn't Stop Crying,” had no effect in preventing postpartum depressive symptoms. Among young mothers aged <25 years, the educational video had a protective effect on postpartum depressive symptoms, which was not observed for mothers aged ≥25 years.

Abstract
Abstract
Background
Parenting by primary caregivers in early childhood is important for the psycho-social development of children. Previous studies reported that the effect of maternal childcare on child behavioral problems. However, the research about the paternal childcare was limited. This study aims to clarify the impact of paternal childcare during infant-period on behavioral problems in later childhood, in terms of 1) childcare hours and 2) type of involvement in childcare.
Methods
We used the data of the Longitudinal Survey of Newborns in the 21st Century (2001-2006), which was a population-based survey in Japan. We analyzed 35,082 samples, excluding single parents. Paternal childcare was assessed by the following; paternal childcare hours on weekdays or weekends at 18 months old, and frequency of each type of childcare (feeding, diaper change, bathing, putting the child to sleep, playing at home, and taking the child outside) at 6 and 18 months old. We evaluated child behavioral problems by the caregiver's answer at 5 years old. Multivariate logistic regression was conducted for analysis.
Results
Children with paternal childcare for ≥ 6 hours on weekends at 18 months old were had fewer behavioral problems at 5 years old than children with paternal childcare for < 4 hours (odds ratio (OR): 0.83, 95% confidence interval (CI): 0.77 to 0,89), while there was no clear association between paternal childcare hours on weekdays and child outcomes. Children with frequent paternal childcare at 6 and 18 months old also had fewer behavioral problems than children with less paternal childcare (OR: 0.83, 95% CI: 0.76 to 0.90). Some types of paternal childcare (feeding, playing at home, and taking the child outside) strongly reduced child behavioral problems at 5 years old, and dose-effect relations were observed (p for trend < 0.001).
Conclusions
Paternal childcare for a longer time on weekends in the infant-period could reduce the child behavioral problems at 5 years old.
Key messages
High paternal involvement in childcare during infant age, such as taking the child outside the home on weekends, could have protective effects on behavioral problems in later childhood. The promotion of paternal involvement in childcare in early childhood should be useful for adequate child development.

Abstract
Cancer vaccines induce cancer-specific T-cells capable of eradicating cancer cells. The impact of cancer peptide vaccines (CPV) on the tumor microenvironment (TME) remains unclear. S-588410 is a CPV comprising five human leukocyte antigen (HLA)-A*24:02-restricted peptides derived from five cancer testis antigens, DEPDC1, MPHOSPH1, URLC10, CDCA1 and KOC1, which are overexpressed in esophageal cancer. This exploratory study investigated the immunologic mechanism of action of subcutaneous S-588410 emulsified with MONTANIDE ISA51VG adjuvant (median: 5 doses) by analyzing the expression of immune-related molecules, cytotoxic T-lymphocyte (CTL) response and T-lymphocytes bearing peptide-specific T-cell receptor (TCR) sequencing in tumor tissue or blood samples from 15 participants with HLA-A*24:02-positive esophageal cancer. Densities of CD8+, CD8+ Granzyme B+, CD8+ programmed death-1-positive (PD-1+) and programmed death-ligand 1-positive (PD-L1+) cells were higher in post- versus pre-vaccination tumor tissue. CTL response was induced in all patients for at least one of five peptides. The same sequences of peptide-specific TCRs were identified in post-vaccination T-lymphocytes derived from both tumor tissue and blood, suggesting that functional peptide-specific CTLs infiltrate tumor tissue after vaccination. Twelve (80%) participants had treatment-related adverse events (AEs). Injection site reaction was the most frequently reported AE (grade 1, n = 1; grade 2, n = 11). In conclusion, S-588410 induces a tumor immune response in esophageal cancer. Induction of CD8+ PD-1+ tumor-infiltrating lymphocytes and PD-L1 expression in the TME by vaccination suggests S-588410 in combination with anti-PD-(L)1 antibodies may offer a clinically useful therapy.Trial registration UMIN-CTR registration identifier: UMIN000023324.

Abstract
AIMS Although distinct DNA methylation patterns have been reported, its localization and roles remain to be defined in heart failure. We investigated the cellular and subcellular localization of DNA methylation and its pathophysiological significance in human failing hearts. METHODS AND RESULTS Using left ventricular (LV) endomyocardial biopsy specimens from 75 patients with dilated cardiomyopathy (DCM; age: 58 ± 14 years old, %female: 32%) and 20 patients without heart failure (controls; age: 56 ± 17 years old, %female: 45%), we performed immunohistochemistry and immunoelectron microscopy for methylated DNA, 5-methylcytosine (5-mC). We next investigated possible relations of the incidence of 5-mC-positive (%5-mC+ ) cardiomyocytes with clinicopathological parameters. Immunopositivity for 5-mC was detected in the cardiomyocytes and other cell types. The %5-mC+ cardiomyocytes was significantly greater in DCM hearts than in controls (57 ± 13% in DCM vs. 25 ± 12% in controls, P < 0.0001). The localization of 5-mC immunopositivity in cardiomyocyte nuclei coincided well with that of heterochromatin, as confirmed by immunoelectron microscopy. Substantial DNA methylation was also observed in interstitial non-cardiomyocytes, but the incidences did not differ between control and DCM hearts (39 ± 7.9% in DCM vs. 41 ± 10% in controls, P = 0.4099). In DCM patients, the %5-mC+ cardiomyocytes showed a significant inverse correlation with LV functional parameters such as heart rate (r = 0.2391, P = 0.0388), end-diastolic pressure (r = 0.2397, P = 0.0397), and ejection fraction (r = -0.2917, P = 0.0111) and a positive correlation with LV dilatation (volume index at diastole; r = 0.2442, P = 0.0347; and volume index at systole; r = 0.3136, P = 0.0062) and LV hypertrophy (mass index; r = 0.2287, P = 0.0484)-that is, LV remodelling parameters. No significant correlations between DNA methylation and the histological parameters of the biopsies, including cardiomyocyte hypertrophy, fibrosis, and inflammatory cell infiltration, were noted. CONCLUSIONS The present study revealed increased nuclear DNA methylation in cardiomyocytes, but not other cell types, from DCM hearts, with predominant localization in the heterochromatin. Its significant relations with LV functional and remodelling parameters imply a pathophysiological significance of DNA methylation in heart failure.

Abstract
In this paper, we have presented a novel Drug Delivery Substrate (DDS) that that is responsive to external stimuli of high-frequency alternating magnetic fields. The DDS is constituted of chitosan crosslinked with PEGDMA (polyethylene glycol dimethacrylate), loaded with Fe3O4 magnetic nanoparticles and vancomycin. In another experiment, a 19-hour elution was observed where three magnetic stimuli of 25 mT, 109.9 kHz were given for 60 min to the test samples. The stimuli were separated by several hours. After excitation span, it was observed that the stimulated samples released a significantly higher amount of vancomycin by as much as 21% compared to non-stimulated samples. In another study, preliminary results showing the effect of different PEGDMA chain lengths have been discussed. These results show evidence of a smart, controllable DDS that allows modulation of its normal passive antibiotic elution by applying external stimuli per personalized needs.

Abstract
Abstract
Background
Childhood maltreatment can have a significant impact on health across the life course, but its impact on health care costs in later life is unknown in Japan. This study aims to assess additional medical costs of Japanese older people with childhood maltreatment history.
Methods
Data from the Japan Gerontological Evaluation Study (JAGES) 2013, a population-based cohort of independent people aged 65 years or older across Japan were used and linked uniquely with the database of health insurance claims for residents of a city with more than 1.5 million citizens, aged 75 years or younger (N = 978). Average annual medical costs for April 2012 and March 2013 and April 2013 and March 2014 were calculated and compared between those who experienced childhood maltreatment and those who did not, using generalized linear models.
Results
4.5% of our sample witnessed their father physically abusing their mother, 1.9% were physically abused, 10.6% were emotionally neglected, and 5.7% were emotionally abused in their childhood. Average medical costs of those with any childhood maltreatment (N = 176, 18.0% of the sample) were significantly higher than those without maltreatment (549,468JPY vs. 413,013JPY (1USD is equivalent to 110JPY); p = 0.007). When examining the effect of each type of maltreatment, average costs of those with emotional neglect were higher than the counterpart (573,481JPY vs. 412,082JPY; p = 0.008). Average costs of those who experienced physical abuse were also higher than those who did not (726,254JPY vs 431,106JPY; p = 0.035). The effect of any childhood maltreatment remained statistically significant after older adults’ age and gender were controlled (p = 0.03).
Conclusions
Our findings suggest that childhood maltreatment is strongly associated with additional medical costs among older Japanese. If it was truly causal, it can be estimated that additional medical costs associated with childhood maltreatment can be more than 333 billion JPY per year nationwide.
Key messages
Average annual medical costs of older adults with any childhood maltreatment history were significantly 116,098 JPY greater than those with no maltreatment history. As for each type of childhood maltreatment, emotional neglect tends to increase medical costs in late adulthood.

Abstract
Abstract
Background
Dental caries is still serious problem among Japanese children. Previous studies suggested that higher consumption of vegetables prevent dental caries. Eating order habit, such as eating vegetables at start of meal, called “Vege-first”, may increase the amount of vegetable consumption, and in turn, prevent dental caries. However, no published studies have examined the impact of “Vege-first” habit on dental caries. The aim of this study to investigate the association between “Vege-first” and dental caries among Japanese children.
Methods
We used the 2015 cross-sectional data from the Adachi Child Health Impact of Living Difficulty (A-CHILD) study, a population-based study of all first-grade students in Adachi City, Tokyo, Japan. The number of DMFT (decayed, missed due to decay, and filled teeth) was used as an outcome. Poisson regression analyses were applied to determine the independent association between “Vege-first” habit and the number of DMFT after controlling for the effects from child’s sex, parents’ marital status, socioeconomic status, and frequency of tooth brushing, drinking sweet beverages, and snacking.
Results
Of 3,689 valid Japanese children participants, 38.2% had DMFT and 11.6% were having the “Vege-first” habit. The number of DMFT decreased linearly with “Vege-first” habit (p < 0.001). After controlled for covariates, the number of DMFT was still significantly and independently decreased with “Vege-first” habit (prevalence ratio=0.89 (95% confidential interval [0.81-0.98])).
Conclusions
This study showed that having the “Vege-first” habit was associated with dental caries even accounting for socioeconomic status, dental health behavior, and dietary habits. Health policy introducing “Vege-first” habit may be effective to prevent pediatric dental caries.

Eating habit which vegetables at start of meal called “Vege-first” may increase the amount of vegetable consumption and possibly reduce dental caries. The habituation of Vege-first was likely to reduce child’s dental caries even accounting for socioeconomic status, dental health behavior and dietary habits.

Abstract
Abstract
Background
Suicide among postpartum women is a new and emerging issue in developed countries. However, little is known about the combined effect of risk factors on self-harm ideation, although various risk factors have been found. The aim of this study is to examine the combined effect of maternal adverse childhood experiences and maternal age on self-harm ideation among postpartum women.
Methods
The study comprised a cross-sectional study of 8,074 mothers participating in a 3-month health checkup between September 2013 and August 2014 in City A, Prefecture A, Japan. Main outcome was self-harm ideation assessed using the Edinburgh Postnatal Depression Scale (EPDS), item 10. Possible risk factors were maternal adverse childhood experiences (ACEs), maternal characteristics, relationship with husband/partner (e.g., feelings when pregnancy was confirmed), household characteristics, child characteristics (e.g., age, sex, birth weight), and postpartum characteristics, and postpartum depression status other than self-harm ideation.
Results
Postpartum women with 3 or more ACEs and younger age (<25 years old) were 10.3 times more likely than those with no ACEs and older age to have self-harm ideation (95%CI=5.3-20.2). This combined effect was also found in first-time mothers (OR = 7.6, 95%CI=3.2-17.9).
Conclusions
Postpartum women with 3 or more ACEs and who were younger than 25 years old were at a high risk for self-harm ideation. Providing prevention strategies aimed at mothers with multiple risk factors, especially younger age and ACEs, is warranted.
Key messages
Mothers with 3 or more ACEs and younger age had a high self-harm ideation risk. Providing prevention strategies for mothers with multiple risk factors is warranted.

Abstract
Abstract
Objective
Maternal mental disorders are known risk factors for child mistreatment. However, little is known about the involvement of maternal developmental disorder traits. The aim of this study was to examine maternal traits related to Pervasive Developmental Disorder (PDD) and Attention Deficit Hyperactivity Disorder (ADHD), and their possible association with child maltreatment.
Methods
Maternal PDD and ADHD were assessed through a self-administered questionnaire (N = 846) during mid-pregnancy using the Pervasive Developmental Disorders Autism Society Japan Rating Scale (PARS) and Adult ADHD Self-Report Scale (ASRS). The mothers completed another questionnaire on child mistreatment when the offspring was approximately 18 months of age. The associations between maternal PDD and ADHD traits and child maltreatment score were analyzed using linear regression models adjusted for covariates.
Results
Mothers who exhibited stronger PDD traits showed significantly higher child maltreatment score, even after adjustment for maternal characteristics at baseline and ADHD traits. At the same time, ADHD traits were significantly associated with child maltreatment after adjustment of covariates, although the association became non-significant after adjustment of PDD traits.
Conclusions
Mothers who showed PDD and ADHD traits during pregnancy were more likely to maltreat their children. It is essential to educate mothers with such traits with appropriate, easy-to-follow childcare instructions, preferably in simple language combined with pictorial aids.
Key messages
Maternal developmental disorder traits are risk factor of child maltreatment. Specific parenting training intervention for mothers with developmental disorders are needed.

Abstract
Background:
Decreased skeletal muscle mass index (SMI) is a major complication of severe chronic heart failure (HF), but no appropriate indices have been developed to predict decreased SMI. Methods and Results:
We enrolled patients with a structural heart disease or history of HF and collected body composition and blood sample data, including serum amino acid concentration. On multivariate logistic regression analysis and receiver operating characteristic curve analysis, serum branched-chain amino acid (BCAA) concentration was a significant predictor of decreased SMI at 1-year follow-up. Conclusions:
Serum BCAA concentration at baseline was significantly associated with decreased SMI at 1-year follow-up.

Abstract
Abstract
Background
Advanced glycation end-products, indicated by skin autofluorescence (SAF) levels, could be prognostic predictors of all-cause and cardiovascular mortality in patients with diabetes mellitus (DM) and renal disease. However, the clinical usefulness of SAF levels in patients with heart failure (HF) who underwent cardiac rehabilitation (CR) remains unclear.
Purpose
The purpose of this study was to investigate the prognostic value of SAF levels in patients with HF who underwent CR.
Methods
This study enrolled 204 consecutive patients with HF who had undergone CR at our university hospital between November 2015 and October 2017. Clinical characteristics and anthropometric data were collected at the beginning of CR. SAF levels were noninvasively measured with an autofluorescence reader. The major adverse cardiovascular event (MACE) was a composite of all-cause mortality and unplanned hospitalization for HF. Follow-up data concerning primary endpoints were collected until November 2018.
Results
Patients' mean age was 68.1 years, and 61% were males. Patients were divided into two groups according to the median SAF levels (high and low SAF groups). Patients in the high SAF group were significantly older, had a higher prevalence of chronic kidney disease, and histories of coronary artery bypass surgery; however, there were no significant between-group differences in sex, prevalence of DM, left ventricular ejection fraction, and physical function. During a median follow-up period of 623 days, 25 patients experienced all-cause mortality and 34 were hospitalized for HF. Kaplan–Meier analysis showed that patients in the high SAF group had a higher incidence of MACE (log-rank P<0.05), whereas when patients were divided into two groups according to the median hemoglobin A1c level, no significant between-group difference was observed for the incidence of MACE (Figure). After adjusting for confounding factors, Cox regression multivariate analysis revealed that SAF levels were independently associated with the incidence of MACE (hazard ratio: 1.74, 95% confidence interval: 1.12–2.65, P<0.05).
Figure 1
Conclusion
SAF levels were significantly associated with the incidence of MACE in patients with HF and may be useful for risk stratification in patients with HF who undergo CR.

Abstract
AIMS The aim of this study was to report the results of custom-made endoprostheses with extracortical plates plus or minus a short, intramedullary stem aimed at preserving the physis after resection of bone sarcomas in children. PATIENTS AND METHODS Between 2007 and 2017, 18 children aged less than 16 years old who underwent resection of bone sarcomas, leaving ≤ 5 cm of bone from the physis, and reconstruction with a custom-made endoprosthesis were reviewed. Median follow-up was 67 months (interquartile range 45 to 91). The tumours were located in the femur in 11 patients, proximal humerus in six, and proximal tibia in one. RESULTS The five-year overall survival rate was 78%. No patient developed local recurrence. The five-year implant survival rate was 79%. In all, 11 patients (61%) developed a complication. Seven patients (39%) required further surgery to treat the complications. Implant failures occurred in three patients (17%) including one patient with aseptic loosening and two patients with implant or periprosthetic fracture. The preserved physis continued to grow at mean 3.3 cm (0 to 14). The mean Musculoskeletal Society score was 88% (67% to 97%). CONCLUSION Custom-made endoprostheses that aim to preserve the physis are a safe and effective option for preserving physeal growth, limb length, and joint function with an acceptable rate of complications.

Abstract
Aims The aim of this study was to determine the risk of local recurrence and survival in patients with osteosarcoma based on the proximity of the tumour to the major vessels. Patients and Methods A total of 226 patients with high-grade non-metastatic osteosarcoma in the limbs were investigated. Median age at diagnosis was 15 years (4 to 67) with the ratio of male to female patients being 1.5:1. The most common site of the tumour was the femur (n = 103) followed by tibia (n = 66). The vascular proximity was categorized based on the preoperative MRI after neoadjuvant chemotherapy into four types: type 1 > 5 mm; type 2 ≤ 5 mm, > 0 mm; type 3 attached; type 4 surrounded. Results Limb salvage rate based on the proximity type was 92%, 88%, 51%, and 0% for types 1 to 4, respectively, and the overall survival at five years was 82%, 77%, 57%, and 67%, respectively (p < 0.001). Local recurrence rate in patients with limb-salvage surgery was 7%, 8%, and 22% for the types 1 to 3, respectively (p = 0.041), and local recurrence at the perivascular area was observed in 1% and 4% for type 2 and 3, respectively. The mean microscopic margin to the major vessels was 6.9 mm, 3.0 mm, and 1.4 mm for types 1 to 3, respectively. In type 3, local recurrence-free survival with limb salvage was significantly poorer compared with amputation (p = 0.025), while the latter offered no overall survival benefit. In this group of patients, factors such as good response to chemotherapy or limited vascular attachment to less than half circumference or longitudinal 10 mm reduced the risk of local recurrence. Conclusion The proximity of osteosarcoma to major blood vessels is a poor prognostic factor for local control and survival. Amputation offers better local control for tumours attached to the blood vessels but does not improve survival. Limb salvage surgery offers similar local control if the tumour attachment to blood vessels is limited. Cite this article: Bone Joint J 2019;101-B:1024–1031.

Abstract
AIMS The aim of this study was to evaluate the prosthesis characteristics and associated conditions that may modify the survival of total femoral endoprosthetic replacements (TFEPR). PATIENTS AND METHODS In all, 81 patients treated with TFEPR from 1976 to 2017 were retrospectively evaluated and failures were categorized according to the Henderson classification. There were 38 female patients (47%) and 43 male patients (53%) with a mean age at diagnosis of 43 years (12 to 86). The mean follow-up time was 10.3 years (0 to 31.7). A survival analysis was performed followed by univariate and multivariate Cox regression to identify independent implant survival factors. RESULTS The revision-free survival of the implant was 71% at five years and 63.3% at ten years. Three prostheses reached 15 years without revision. The mean Musculoskeletal Tumor Society score in the group was 26 (23 to 28). The mechanisms of failure were infection in 18%, structural failures in 6%, tumour progression in 5%, aseptic loosening in 2%, and soft-tissue failures in 1%. Prostheses used for primary reconstruction after oncological resections had lower infection rates than revision implants (8% vs 25%; p = 0.001). The rates of infection in silver-coated and non-silver-coated prosthesis were similar (17.4% vs 19.%; p = 0.869). The incidence of hip dislocation was 10%. Rotating hinge prosthesis had a lower failure rate than fixed hinge prosthesis (5.3% vs 11%). After Cox regression, the independent factors associated with failures were the history of previous operations (hazard ratio (HR) 3.7; p = 0.041), and the associated arthroplasty of the proximal tibia (HR 3.8; p = 0.034). At last follow-up, 11 patients (13%) required amputation. CONCLUSION TFEPR offers a reliable reconstruction option for massive bone loss of the femur, with a good survival when the prosthesis is used as a primary implant. The use of a rotating hinge at the knee and dual mobility bearing at the hip may be adequate to reduce the risk of mechanical and soft-tissue failures. Infection remains the main concern and there is insufficient evidence to support the routine use of silver-coated endoprosthesis. Cite this article: Bone Joint J 2019;101-B:522-528.

Abstract
AIMS The aim of this paper was to investigate the prognostic factors for local recurrence in patients with pathological fracture through giant cell tumours of bone (GCTB). PATIENTS AND METHODS A total of 107 patients presenting with fractures through GCTB treated at our institution (Royal Orthopaedic Hospital, Birmingham, United Kingdom) between 1995 and 2016 were retrospectively studied. Of these patients, 57 were female (53%) and 50 were male (47%).The mean age at diagnosis was 33 years (14 to 86). A univariate analysis was performed, followed by multivariate analysis to identify risk factors based on the treatment and clinical characteristics. RESULTS The initial surgical treatment was curettage with or without adjuvants in 55 patients (51%), en bloc resection with or without reconstruction in 45 patients (42%), and neoadjuvant denosumab, followed by resection (n = 3, 3%) or curettage (n = 4, 4%). The choice of treatment depended on tumour location, Campanacci tumour staging, intra-articular involvement, and fracture displacement. Neoadjuvant denosumab was used only in fractures through Campanacci stage 3 tumours. Local recurrence occurred in 28 patients (25%). Surgery more than six weeks after the fracture did not affect the risk of recurrence in any of the groups. In Campanacci stage 3 tumours not treated with denosumab, en bloc resection had lower local recurrences (13%), compared with curettage (39%). In tumours classified as Campanacci 2, intralesional curettage and en bloc resections had similar recurrence rates (21% and 24%, respectively). After univariate analysis, the type of surgical intervention, location, and the use of denosumab were independent factors predicting local recurrence. Further surgery was required 33% more often after intralesional curettage in comparison with resections (mean 1.59, 0 to 5 vs 1.06, 0 to 3 operations). All patients treated with denosumab followed by intralesional curettage developed local recurrence. CONCLUSION In patients with pathological fractures through GCTB not treated with denosumab, en bloc resection offers lower risks of local recurrence in tumours classified as Campanacci stage 3. Curettage or resections are both similar options in terms of the risk of local recurrence for tumours classified as Campanacci stage 2. The benefits of denosumab followed by intralesional curettage in these patients still remains unclear.

Abstract
Aims The aim of this study was to describe, analyze, and compare the survival, functional outcome, and complications of minimally invasive (MI) and non-invasive (NI) lengthening total femoral prostheses. Patients and Methods A total of 24 lengthening total femoral prostheses, 11 MI and 13 NI, were implanted between 1991 and 2016. The characteristics, complications, and functional results were recorded. There were ten female patients and ten male patients. Their mean age at the time of surgery was 11 years (2 to 41). The mean follow-up was 13.2 years (seven months to 29.25 years). A survival analysis was performed, and the failures were classified according to the Modified Henderson System. Results The overall implant survival was 79% at five, ten, and 20 years for MI prostheses, and 84% at five years and 70% at ten years for NI prostheses. At the final follow-up, 13 prostheses did not require further surgery. The overall complication rate was 46%. The mean revision-free implant survival for MI and NI prostheses was 59 months and 49 months, respectively. There were no statistically significant differences in the overall implant survival, revision-free survival, or the distribution of complications between the two types of prosthesis. Infection rates were also comparable in the groups (9% vs 7%; p = 0.902). The rate of leg-length discrepancy was 54% in MI prostheses and 23% in NI prostheses. In those with a MI prosthesis, there was a smaller mean range of movement of the knee (0° to 62° vs 0° to 83°; p = 0.047), the flexion contracture took a longer mean time to resolve after lengthening (3.3 months vs 1.07 months; p < 0.001) and there was a lower mean Musculoskeletal Tumor Society (MSTS) score (24.7 vs 27; p = 0.295). Conclusion The survival and complications of MI and NI lengthening total femoral prostheses are comparable. However, patients with NI prosthesis have more accurate correction of leg-length discrepancy, a better range of movement of the knee and an improved overall function.

In her endomyocardial biopsy specimen, we observed under electron microscopy six scenes in which degenerative cardiomyocytes were engulfed by neighbouring cardiomyocytes. The enclosed cardiomyocytes appeared more degenerative than the enclosing ones in every pair: the myofibrils were more severely damaged. At more degenerative stages, some desmosomes of the intercalated discs on the enclosed cardiomyocyte had disappeared. The membranes between the cardiomyocytes were occasionally disrupted, and there appeared to be sharing of cellular contents between the cells. One pair of such a phagocytosis‐like figure was observed in one case with 5‐fluorouracil cardiomyopathy (a 68‐year‐old man) among eight other chemotherapy‐induced cardiomyopathies but none among 30 non‐drug‐induced dilated cardiomyopathies. The findings suggest a mechanism for disposal of degenerative cardiomyocytes in human failing hearts: phagocytosis by a neighbour, although alternative interpretations remain (e.g. giant autophagic vacuoles or two cardiomyocytes with degenerative intercalated discs).

Abstract
When the Budd-Chiari syndrome (BCS) lesion extends to the inferior vena cava (IVC) or the orifices of the hepatic vein, the thickened IVC and/or hepatic vein wall must be removed and IVC reconstruction is required in living-donor liver transplantation (LDLT). In various reports about IVC resection in LDLT for BCS, there are none about left lobe liver transplantation with reconstruction of the retrohepatic IVC (rhIVC). To overcome removal and reconstruction of the rhIVC in LDLT for BCS, we introduced a composite IVC graft that is applicable to both right and left lobe partial liver grafts for LDLT for BCS. Pathogenic IVC was removed together with the native liver between the lower edge of the right atrium and 5 cm above the renal vein junction with the use of venovenous bypass. The e-polytetrafluoroethylene graft was anastomosed to the suprarenal intact IVC. Then the native part was detached at the level of just above the renal junction. The composite graft was inverted and a half rim of the native part of the graft was anastomosed to the posterior wall of the right atrium. Next, the common venous orifice of the left lobe graft was anastomosed to the wall defect which was composed of the anterior wall of the right atrium and the distal end of the native part of the composite graft. In conclusion, our inverted composite graft technique will overcome the weak points of LDLT for BCS, such as incomplete removal of the pathogenic caval wall and reconstruction of the rhIVC.
