Abstract
It is often assumed that future coastal cliff retreat rates will accelerate as global sea level rises, but few studies have investigated how SLR (sea level rise) might change cliff-front wave dynamics. Using a new simple numerical model, this study simulates the number and type (breaking, broken, or unbroken) of cliff-front waves under future SLR scenarios. Previous research shows breaking waves deliver more energy to cliffs than broken waves, and unbroken waves generate minimal impact. Here, we investigated six cliff-platform profiles from three regions (USA, New Zealand, and UK) with varied tidal ranges and wave climates. Model inputs included 2013-2100 hindcast/forecast incident wave height and tidal water level, and three future SLR scenarios. Results show the number of both cliff-front breaking and broken waves generally increase for a high-elevation (relative to tide) cliff-platform junction. In contrast, breaking/broken wave occurrence decrease by 38-92% for a near-horizontal shore platform with a low-elevation cliff-platform junction under a high SRL scenario, leading to high (96-97%) unbroken wave occurrence. Overall, results suggest the response of cliff-front waves to future SLR is complex and depends on shore platform geometries and SLR scenarios, indicating that future cliff retreat rates may not homogeneously accelerate under SLR.

Abstract
BACKGROUND The effect of physician-patient sex concordance in medicine has been reported in many studies. Whether physicians believe that the sex concordance between physician and athlete influences treatment has not been investigated. OBJECTIVE To determine whether physicians believe that the sex concordance between physician and athlete influences treatment. DESIGN Cross-sectional study. SETTING Online survey. PARTICIPANTS One thousand one hundred ninety-three sports medicine physicians in 51 countries. Participants were sports medicine physicians trained in orthopedics (n = 443 [37.1%]) and nonorthopedics (n = 750 [62.9%]). INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Participants were asked to decide whether sex of the physician made them better suited to care for athletes of concordant or different sexes along with their personal background. RESULTS Orthopedic sports medicine physicians agreed less than nonorthopedic sports medicine physicians regarding the statement "MALE sports medicine physicians are better suited than their female counterparts to care for MALE athletes" (odds ratio [OR] 0.56, 95% confidence interval [CI] 0.35-0.91, p = .02), and compared to sports medicine physicians based in Europe, those based in Asia agreed more to this statement (OR 7.91, 95% CI 4.60-13.60, p < .01). In addition, regarding the statement "FEMALE sports medicine physicians are better suited than their male counterparts to care for FEMALE athletes," compared to sports medicine physicians based in Europe, those based in Asia (OR 9.12, 95% CI 5.63-14.79, p < .01) and North America (OR 2.18, 95% CI 1.46-3.25, p < .01) agreed more and orthopedic sports medicine physicians agreed less than nonorthopedic sports medicine physicians (OR 0.61, 95% CI 0.39-0.93, p = .02) to this statement. CONCLUSIONS Sports medicine physicians trained in orthopedics felt sex concordance was less important than physicians trained in other specialties. Asian sports medicine physicians believed sex concordance was more important compared to physicians in other regions.

Abstract
OBJECTIVE To clarify whether perioperative immunonutrition is effective in adult patients with or without malnutrition undergoing elective surgery for head and neck (HAN) or gastrointestinal (GI) cancers. BACKGROUND It is important to avoid postoperative complications in patients with cancer as they can compromise clinical outcomes. There is no consensus on the efficacy of perioperative immunonutrition in patients with or without malnutrition undergoing HAN or GI cancer surgery. MATERIALS AND METHODS We searched MEDLINE (PubMed), MEDLINE (OVID), EMBASE, Cochrane Central Register of Controlled Trials, Web of Science Core Selection, and Emcare from 1981 to 2022 using search terms related to immunonutrition and HAN or GI cancer. We included randomized controlled trials. Intervention was defined as immunonutritional therapy including arginine, n-3 omega fatty acids, or glutamine during the perioperative period. The control was defined as standard nutritional therapy. The primary outcomes were total postoperative and infectious complications, defined as events with a Clavien-Dindo classification grade ≥ II that occurred within 30 days after surgery. RESULTS Of the 4825 patients from 48 included studies, 19 had upper GI cancer, 9 had lower, and 8 had mixed cancer, whereas 12 had HAN cancers. Immunonutrition reduced the total postoperative complications (relative risk ratio: 0.78; 95% CI, 0.66-0.93; certainty of evidence: high) and infectious complications (relative risk ratio: 0.71; 95% CI, 0.61-0.82; certainty of evidence: high) compared with standard nutritional therapy. CONCLUSIONS Nutritional intervention with perioperative immunonutrition in patients with HAN and GI cancers significantly reduced total postoperative complications and infectious complications.

Abstract
OBJECTIVES Supporting female sports medicine physicians to simultaneously be mothers and pursue professional careers is crucial to maintain gender diversity in sports medicine physicians. The purpose of this study is to understand the attitudes toward female sports medicine physicians during pregnancy and postpartum. METHODS An anonymous online survey was distributed to sports medicine physicians practicing in 51 different countries. They were asked how comfortable they felt with female sports medicine physicians working on the sidelines of sporting events during pregnancy, if the female sports medicine physicians were as productive as their male counterparts after giving birth, and how satisfied they were with the percentage of female sports medicine physicians in their country. Data were analyzed using the chi-square test, and multivariate logistic regression analysis was performed to identify independent variables. RESULTS In total, 1193 physicians (380 [31.9%] female) were included for analysis. Physicians in Asia were the least comfortable with pregnant sports medicine physicians working on the sidelines and those in North America were the most comfortable (odds ratio = 0.28 and 2.51, 95% confidence interval 0.18-0.44 and 1.55-4.06, respectively). More experienced sports medicine physicians (odds ratio = 1.01, 95% confidence interval 1.00-1.03; p < 0.05) and divorced physicians (odds ratio = 0.33, 95% confidence interval 0.12-0.91; p < 0.05) were less comfortable with pregnant female sports medicine physicians working on sidelines, and those trained in orthopedics were less likely to agree that female sports medicine physicians were equally as productive as male counterparts postpartum (odds ratio = 0.29, 95% confidence interval 0.10-0.88; p < 0.05). Female physicians were less satisfied with the percentage of female sports medicine physicians in their country (odds ratio = 0.41, 95% confidence interval 0.27-0.60; p < 0.01) than their male counterparts. CONCLUSIONS Female sports medicine physicians may experience bias in their practice during pregnancy and postpartum.

Abstract
BACKGROUND/AIM To ascertain whether preoperative neo-adjuvant nutritional therapy (NANT) using eicosapentaenoic acid (EPA) supplementation can provoke a rise in blood levels of EPA capable of restricting NF-B nuclear translocation in resected specimens. PATIENTS AND METHODS Patients were allocated to two groups depending on individual preference: Patients in the treatment group received 2 g of EPA daily for two weeks prior to surgery (NANT group, n=18). Patients in the control group had a normal diet (CONT group, n=26). NF-B translocation rate, in specimens collected, was investigated by histopathology. Five hundred malignant cells were counted, and tissues with 10% or higher NF-B nuclear translocation were determined to be positive. RESULTS The EPA blood concentration rose significantly in the NANT group (p<0.01). The positive rate of NF-B nuclear translocation in cancer cells was 11.1% in the NANT group compared with 50% in the CONT group. This difference was statistically significant (p<0.01). CONCLUSION Increased blood concentrations of EPA after preoperative supplementation was associated with suppression of NF-B nuclear translocation in malignant cells. These results suggest that intake of EPA-containing supplements before surgery can control NF-B activation and by extension, cancer aggressiveness.

Abstract
INTRODUCTION In women, the female athlete triad, marked by low energy availability, functional hypothalamic amenorrhea and osteoporosis, is a recognized risk for stress fractures. Stress injuries also occur in men, but by contrast risks and mechanisms underlying them are less characterized. MATERIALS AND METHODS 5 week-old wild-type male mice were fed ad libitum (ad) or subjected to 60% food restriction (FR) for five weeks. In both groups, some mice were allowed access to an exercise wheel in cages to allow voluntary wheel running (ex) and/or treated with active vitamin D analogues. Mice were sacrificed and analyzed at 10 weeks of age. RESULT Male FR mice exhibited significantly reduced testicle weight, serum testosterone levels and bone mass. Such bone losses in FR male mice were enhanced by exercise. Histological analysis revealed that both bone-resorbing and -forming activities were significantly reduced in FR or FR plus exercise (FR + ex) mice, mimicking a state of low bone turnover. Significantly reduced bone mass in FR or FR + ex male mice was significantly rescued by treatment with active vitamin D analogues, with significant restoration of osteoblastic activities. Serum levels of insulin-like growth factor I (IGF-I), which is critical for bone remodeling, were significantly lower in FR versus control male mice. CONCLUSIONS Low energy availability puts men at risk for stress injuries as well, and low energy availability is upstream of gonadal dysfunction and osteoporosis in males. Active vitamin D analogues could serve as therapeutic or preventive options for stress injuries in men.

Abstract
Diet is considered as a major driver of gut microbiota composition. However, little is known about the relationship between overall dietary balance and gut microbiota, especially in the elderly. Here, using the Quantitative Index for Dietary Diversity (QUANTIDD), we analysed the relationships between dietary diversity and gut microbiota diversity in 445 Japanese subjects aged 65-90 years. We also examined the effect of age by comparing the young-old group aged 65 to 74 years (<75 years group; n=246) and the old-old group aged 75 years and older (≥75 years group; n=199). QUANTIDD showed significant positive relationships with Pielou's evenness and Shannon indices, two α-diversity indices related to the uniformity of species distribution. This suggests that a more diverse diet is associated with a more uniform abundance of various bacterial groups, rather than a greater variety of gut bacteria. QUANTIDD also showed significant positive associations with the abundance of Anaerostipes, Eubacterium eligens group, and Eubacterium ventriosum group, which produce short-chain fatty acids (SCFAs) and are beneficial to health. Negative association was found with the abundance of Ruminococcus gnavus group, which produces inflammatory polysaccharides. Positive associations between QUANTIDD and α-diversity indices or the abundance of specific bacterial groups were identified among all subjects and in the <75 years group, but not in the ≥75 years group. Our results suggest that dietary diversity contributes to the diversity of the gut microbiota and increases the abundance of SCFAs-producing bacteria, but only up to a certain age. These findings help to understand the complex relationship between diet and gut microbiota, and provide hints for specific dietary interventions to promote beneficial gut microbiota in the elderly.

Abstract
Abstract
Background
Recent clinical study suggests newer-generation drug-eluting stents (DES) that combine ultrathin strut and nano-coating with biodegradable polymers sirolimus-eluting stent (BP-SES) could improve long-term clinical outcomes in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) over current generation DES. However, the details of vascular response in very early and chronic phase have not been systematically addressed.
Objective and method
We exploratory investigate early and chronic vascular response following BP-SES implantation in patients with STEMI to reveal mechanism of the favorable clinical outcomes in recent studies using frequency domain-optical coherence tomography (FD-OCT).
Consecutive twenty-four patients with STEMI who underwent FD-OCT after primary PCI and were eligible for follow-up FD-OCT at 2 weeks and 1 year after implantation were enrolled between June 2018 and August 2020.
OCT was performed immediately after PCI, at 2-weeks (2W) and 1-year (1Y) after the primary PCI. Struts were recorded as uncovered if any part was visibly exposed in the lumen or covered if a layer of tissue covered all reflecting surfaces. Struts of stents that are smaller than 3.0mm of diameter with more than 80μm between the center reflection and the adjacent vessel surface were recorded as malapposed. The reduction of atherothrombotic protrusion burden within the stent was also assessed.
Results
Twenty-four patients (age 64.9±11.4 years, male 83.3%) were enrolled.
The percentage of uncovered struts significantly decreased from post-PCI to 2W follow-up and from 2W follow-up to 1Y follow-up (62±20% post-PCI versus 27±11% at 2W follow up, p<0.0001 and 2W follow-up versus 3.3±3.3% at 1Y follow up, p<0.0001). Malapposed struts also decreased from post-PCI to 2W follow-up (4.1±3.6% post-PCI versus 1.5±2.2% at 2W follow-up, p<0.0001), but no significant difference was shown between 2W follow-up and 1Y follow-up (2W follow-up versus 1.0±2.3 at 1Y follow up, p=0.12). The average protrusion area of athero-thrombotic burden decreased (0.57±0.32 at post-PCI versus 0.42±0.22 mm2 at 2W follow up, p<0.0001) and its volume showed similar tendency (16.6±10.7 at post-PCI versus 12.9±8.23 mm3 at 2W follow up, p=0.0011). Thrombus was shown in all patients at post-PCI, but two patients (8.0%) showed it at 1Y follow-up.
Conclusion(s)
This study elucidated very early and chronic vascular responses following ultrathin strut BP-SES implantation in STEMI patients by FD-OCT. It showed resolution of athero-thrombotic materials in very early phase and favorable progression of strut coverage in very early and chronic phase.

Abstract
Abstract
Background
There are have been reports on the 12-lead ECG waveforms used to identify ventricular premature contractions (VPCs), but there are not enough algorithms. On the other hand, the synthesized 18-lead ECG adds the right-side chest leads (V3R, V4R, and V5R) and back leads (V7, V8, and V9) to the 12-lead ECG.
Purpose
This aim of this study was to evaluate whether the waveforms of the 18-lead ECG are useful in predicting the origin of VPCs.
Methods
We studied 86 consecutive patients (age :61.8±16.0 years, male: 54.5%) enrolled from multicenter who underwent radiofrequency catheter ablation for VPCs. We retrospectively investigated the association between origin of the VPCs and characteristics of the synthetic 18-leads ECG.
Results
The 18-lead ECG showed a specific pattern for the VPC originating near the His-bundle. In 17 cases, the QRS morphology in V5R exhibited a QS pattern, and 13 of 17 cases had VPCs originating near the His-bundle. In the other 69 cases, V5R did not exhibit a QS pattern. ROC curve analysis showed that the QS pattern in V5R predicted VPC originating near the His-bundle with high accuracy: sensitivity 100.0%, specificity 94.5%, and AUC 0.98. Furthermore, the positive predictive value was 76.5% and negative predictive value 100.0%.
Conclusion
The QS pattern shown in V5R of the 18-lead ECG was a useful parameter for identifying VPCs originating near the His-bundle, which might be a good reference indicator during radiofrequency catheter ablation for VPCs.

Abstract
Nocturnal enuresis (NE) is a syndrome associated with abnormal nocturnal urine production, urination mechanism, and sleep arousal. NE is strongly associated with attention-deficit/hyperactivity disorder (ADHD), and it has been reported that NE occurs in approximately 30% of children with ADHD. There have been several reports on the efficacy of atomoxetine as treatment for NE with ADHD, while the efficacy of guanfacine is still limited. We report our experience of treating an 10-year-old girl with NE with ADHD with a single dose of guanfacine. The patient first visited our hospital because of difficulty concentrating, restlessness at home and school, and nocturnal incontinence. She was diagnosed with NE with ADHD based on a review of her personal history from her mother. Her NE symptoms improved with guanfacine monotherapy (1 mg/day. The patient weighed 28 kg).

Abstract
Purpose Most studies have investigated the differences in postgastrectomy quality of life (QOL) based on the surgical procedure or reconstruction method adopted; only a few studies have compared QOL based on tumor location. This large-scale study aims to investigate the differences in QOL between patients with esophagogastric junction cancer (EGJC) and those with upper third gastric cancer (UGC) undergoing the same gastrectomy procedure to evaluate the impact of tumor location on postoperative QOL. Methods The Postgastrectomy Syndrome Assessment Scale-45 (PGSAS-45) questionnaire was distributed in 70 institutions to 2,364 patients who underwent gastrectomy for EGJC or UGC. A total of 1,909 patients were eligible for the study, and 1,744 patients who underwent total gastrectomy (TG) or proximal gastrectomy (PG) were selected for the final analysis. These patients were divided into EGJC and UGC groups; thereafter, the PGSAS-45 main outcome measures (MOMs) were compared between the two groups for each type of gastrectomy. Results Among the post-TG patients, only one MOM was significantly better in the UGC group than in the EGJC group. Conversely, among the post-PG patients, postoperative QOL was significantly better in 6 out of 19 MOMs in the UGC group than in the EGJC group. Conclusions Tumor location had a minimal effect on the postoperative QOL of post-TG patients, whereas among post-PG patients, there were definite differences in postoperative QOL between the two groups. It seems reasonable to conservatively estimate the benefits of PG in patients with EGJC compared to those in patients with UGC.

Abstract
OBJECTIVES To evaluate the difference between female and male sports medicine physicians regarding disrespectful attitudes and sexual harassment perceived from athletes, coaches, physicians, athletic trainers (ATs) and organisations/administrations. METHODS AND STUDY DESIGN anonymous survey was distributed to sports medicine physicians practicing in 51 countries. χ2 analysis was used to detect differences between female and male sports medicine physicians and logistic regression analysis was used to determine the independent variables that affect disrespectful attitudes and sexual harassment from sports participants. RESULTS 1193 sports medicine physicians (31.9% female) participated from 51 countries. The survey revealed that female physicians, compared with male physicians, perceive significantly more disrespect or have their judgement questioned more by the following categories: male and female athletes, male and female coaches, female physicians with more years of experience, male physicians (regardless of years of experience), male and female ATs and organisation/administrations (all p<0.05). The only category where the frequency of disrespect was perceived equally by male and female physicians was during their interactions with female physicians who have the same or lesser years of experience. Female sports medicine physicians noted more sexual harassment than male physicians during interactions with male athletes, coaches, ATs and physicians (all p<0.001). In the logistic regression, gender was a related factor for perceiving disrespect, especially from male coaches (OR=2.01) and physicians with more years of experience (OR=2.18). CONCLUSIONS Female sports medicine physicians around the world experience disrespectful attitudes, questioning of their judgement and are sexually harassed significantly more often than male counterparts.

Abstract
Objective: The goal of this study was to evaluate the efficacy and safety of duloxetine in children and adolescents (9-17 years of age) with major depressive disorder (MDD) in Japan. Methods: This study consists of two clinical trials. First, a 6-week, randomized double-blind placebo-controlled clinical trial (RCT) was conducted. The primary endpoint of RCT was the change in Children's Depression Rating Scale-Revised (CDRS-R) total scores from baseline. Following RCT, an open-label long-term extension trial (OLE) was conducted to investigate the longer-term safety of duloxetine for ∼1 year. Results: In RCT, CDRS-R total score changes from baseline to 6 weeks after the start of administration (primary endpoint) were -21.03 in the duloxetine group (n = 74) and -22.42 in the placebo group (n = 74). No significant difference was observed in the primary endpoint between the groups (p = 0.5587). In addition, no significant difference was observed in secondary endpoints such as CDRS-R response rates. The proportion of patients with ≥1 treatment-emergent adverse event (TEAE) in RCT was significantly higher in the duloxetine group (78.7%) than in the placebo group (62.2%), and most were mild or moderate in severity. Changes in CDRS-R total scores during OLE, in consecutive patients from the duloxetine group in RCT (n = 63), or placebo group (n = 59) in RCT, and newly enrolled patients (n = 28), were -12.1, -11.3, and -17.8, respectively. The proportion of patients with ≥1 TEAE in OLE was 90.5%, 88.1%, and 89.3% in the respective groups, and most of them were mild or moderate in severity. Conclusions: Duloxetine did not show superiority to placebo in efficacy in children and adolescents with MDD in Japan. Overall reported TEAEs were consistent with the currently available duloxetine safety profile and no new safety finding was observed in the two clinical trials.

Abstract
Aim S‐flurbiprofen plaster (SFPP) is a novel topical nonsteroidal anti‐inflammatory drug (NSAID) patch. This study aimed to assess the efficacy and safety of SFPP in knee osteoarthritis (OA) patients compared to diclofenac gel. Methods This study was a multicenter, randomized, active‐controlled, open‐label, non‐inferiority phase III trial. There were 311 enrolled patients treated by SFPP or diclofenac gel for 2 weeks. The primary efficacy outcome was the knee pain when rising from the specially arranged chair assessed by visual analog scale (rVAS). The other efficacy outcomes were clinical symptoms, pain on walking, global assessment by both investigator and patient, and use/non‐use of the rescue drugs during the treatment period. Adverse events (AEs) were evaluated as the safety outcome. Results The least‐squares mean (95% CI) of ΔrVAS at the end of the study was 41.52 (39.16‐43.88) mm in the SFPP group and 36.01 (33.69‐38.33) mm in the diclofenac gel group, with a between‐group difference of 5.51 (2.20‐8.82), indicating non‐inferiority. There were statistically significant differences between the groups in rVAS, clinical symptoms, pain on walking, and the global assessment by both investigator and patient. The incidence rate of AEs in the SFPP group was 5.8%, and there was no statistically significant difference from that in the diclofenac gel group (5.2%). Most of the AEs were mild, and no AE led to discontinuation. Conclusion Non‐inferiority of SFPP to diclofenac gel was demonstrated in the efficacy for pain on rising from a chair. SFPP was also well‐tolerated in knee OA patients.

Abstract
Background Patients with gastric cancer are aging in Japan. It is not clear which patients and which surgical procedures have survival benefits after gastrectomy. A multivariate analysis was performed. Methods The medical records of 166 patients aged ≥ 80 years who underwent gastrectomy without macroscopic residual tumors were retrospectively reviewed. Univariate and multivariate analyses using Cox proportional hazard models were performed to detect prognostic factors for overall survival. Results In univariate analyses, age (≥ 90 vs. ≥ 80, < 85), performance status (3 vs. 0), American Society of Anesthesiologists physical status (ASA-PS) (3, 4 vs. 1, 2), Onodera’s prognostic nutritional index (< 40 vs. ≥ 45), the physiological score of the Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity (POSSUM) (≥ 40 vs. ≥ 20, ≤ 29), surgical approach (laparoscopic vs. open), extent of gastrectomy (total, proximal vs. distal), extent of lymphadenectomy (D1 vs. ≥ D2), pathological stage (II–IV vs. I), and residual tumor (R1 vs. R0) were significantly correlated with worse overall survival. Multivariate analysis revealed that ASA-PS [3, 4 vs. 1, 2, hazard ratio (HR) 2.30, 95% confidence interval (CI) 1.24–4.24], extent of gastrectomy (total vs. distal, HR 2.17, 95% CI 1.10–4.31) (proximal vs. distal, HR 4.05, 95% CI 1.45–11.3), extent of lymphadenectomy (D0 vs. ≥ D2, HR 12.4, 95% CI 1.58–97.7), and pathological stage were independent risk factors for mortality. Conclusions ASA-PS was a useful predictor for postoperative mortality. Gastrectomy including cardia is best avoided.

Abstract
Changes in bone metabolism occur in mothers during pregnancy or lactation that may decrease bone mass and result in fragility fractures after partum. However, use of drugs during pregnancy or lactation to counteract these effects is often prohibited or strongly discouraged. Therefore, approaches to protect mothers from fragility fractures have not been established. Here we show that bone mineral density was significantly lower in female mice after partum than in age-matched female mice without partum. We also show that temporary administration of the bisphosphonate alendronate, either just before or just after pregnancy, to female mice was protective against bone loss due to pregnancy or lactation and had no adverse effects on offspring, such as growth retardation. Furthermore, we show that alendronate administration to female mice during lactation was effective in increasing bone mass in mothers without promoting bone abnormalities or growth retardation in offspring. Calcium levels in milk from female mice administered alendronate during lactation were equivalent to those in milk from mothers not treated with alendronate. Overall, we propose that alendronate administration to mothers could prevent bone loss and fragility fractures during pregnancy and lactation.

Abstract
INTRODUCTION Since the definition of secondary amenorrhea is cessation of regular menses for more than 3 months, it is likely that athletes with irregular menstrual cycles, including oligomenorrhea, do not consider the condition as serious. However, the consequences of untreated oligomenorrhea have not been investigated in elite track and field athletes. MATERIALS AND METHODS The cohort consisted of 91 elite-level track and field athletes. Body compositions, including bone parameters and bone turnover markers (BTMs), were measured. RESULTS Among the 91 participants, 52 were eumenorrheic and 33 were oligomenorrheic. The eumenorrheic athletes had significantly higher bone mineral density (BMD) and bone mineral content (BMC) of the lumbar spine, lower extremities, and whole body than had the oligomenorrheic athletes (p < 0.01). There were no significant differences in BTMs between the two groups, but oligomenorrheic athletes had significantly lower percent body fat. CONCLUSION More than 40% of the elite-level female track and field athletes in this study reported menstrual disorders with oligomenorrhea as the most common. However, none sought medical attention. As compared to the eumenorrheic athletes, the oligomenorrheic athletes had lower BMC and BMD. Hence, if an athlete is oligomenorrheic, bone parameter measurements are considerably important.

Abstract
Abstract
Background
Atherosclerotic plaque quantification from coronary computed tomography angiography (CTA) enables accurate assessment of coronary artery disease burden, progression, and prognosis. However, quantitative plaque analysis is time-consuming and requires high expertise. We sought to develop and externally validate an artificial intelligence (AI)-based deep learning (DL) approach for CTA-derived measures of plaque volume and stenosis severity. We compared the performance of DL to expert readers and the gold standard of intravascular ultrasound (IVUS).
Methods
This was a multicenter study of patients undergoing coronary CTA at 11 sites, with software-based quantitative plaque measurements performed at a per-lesion level by expert readers. AI-based plaque analysis was performed by a DL novel convolutional neural network which automatically segmented the coronary artery wall, lumen, and plaque for the computation of plaque volume and stenosis severity. Using expert measurements as ground truth, the DL algorithm was trained on 887 patients (4,686 lesions). Thereafter, the algorithm was applied to an independent test set of 221 patients (1,234 lesions), which included an external validation cohort of 171 patients from the SCOT-HEART (Scottish Computed Tomography of the Heart) trial as well as 50 patients who underwent IVUS within one month of CTA. We report the performance of AI-based plaque analysis in the independent test set.
Results
Within the external validation cohort, there was excellent agreement between DL and expert reader measurements of total plaque volume (intraclass correlation coefficient [ICC] 0.876), noncalcified plaque volume (ICC 0.869), and percent diameter stenosis (ICC 0.850; all p<0.001). When compared with IVUS, there was excellent agreement for DL total plaque volume (ICC 0.945), total plaque burden (ICC 0.853), minimal luminal area (ICC 0.864), and percent area stenosis (ICC 0.805; all p<0.001); with strong correlation between DL and IVUS for total plaque volume (r=0.915; p<0.001; Figure). The average DL plaque analysis time was 20 seconds per patient, compared with 25–30 minutes taken by experts.
Conclusions
AI-based plaque quantification from coronary CTA using an externally validated DL approach enables rapid measurements of plaque volume and stenosis severity in close agreement with expert readers and IVUS.

Abstract
OBJECTIVE Despite the high frequency of depression in the first year following stroke, few studies have predicted risk of depression after the acute and subacute stroke periods. The aim of this study was to identify, in the acute and subacute periods, measures that would predict major depression during the first year after stroke. METHODS Study subjects were inpatients with ischemic stroke aged 20-85 years within 6 weeks of onset. Patients were evaluated at baseline and at 3, 6, 9, and 12 months. Patients were diagnosed with major depression using the Structured Clinical Interview for DSM-IV. The severity of depressive symptoms was measured with the Patient Health Questionnaire-9 (PHQ-9) and the Montgomery-Åsberg Depression Rating Scale (MADRS). RESULTS Of the 152 potential patients who met inclusion criteria, 49 had follow-up evaluations; one patient with major depression in the acute and subacute periods was excluded from the analysis. Among the remaining 48 patients, the number of those with major depression during the first year of stroke onset was five (10.4%). Patients who developed major depression had significantly more depressive symptoms in the acute and subacute stroke phase as assessed by both the PHQ-9 and MADRS. Patients with PHQ-9 scores ≥9 in the acute and subacute stroke phases were significantly more likely to develop major depression in a chronic phase of stroke. CONCLUSIONS The self-administered PHQ-9 can identify patients in the acute and subacute stroke periods who are at increased risk for developing major depression during the first year after stroke.

Abstract
BACKGROUND Although some studies have described the association between serum ferritin levels and specific disorders in child and adolescent psychiatry, few have focused on mental health with low serum ferritin levels in children and adolescents. This study examined the effects of iron administration on psychological state of children and adolescents with reduced serum ferritin concentration. METHODS This prospective study evaluated 19 participants aged 6-15 years with serum ferritin levels <30 ng/mL who visited a mental health clinic and received oral iron administration for 12 weeks. The participants were assessed using the Clinical Global Impression Severity (CGI-S), Profile of Mood States 2nd Edition Youth-Short (POMS), Center for Epidemiologic Studies Depression Scale (CES-D), and Pittsburgh Sleep Quality Index (PSQI). In addition to serum ferritin, blood biochemical values such as hemoglobin (Hb) and mean corpuscular volume (MCV) were examined. School attendance was recorded. RESULTS The most prevalent physical symptoms were fatigability and insomnia. The CGI-S, PSQI, and CES-D scores decreased significantly following iron supplementation, whereas the scores of almost all POMS subscales improved significantly at week 12. No participant had hemoglobin levels <12 g/dL. Serum ferritin concentration increased significantly, whereas Hb and MCV remained unchanged. At baseline, 74% of the participants did not attend school regularly; this number improved to varying degrees by week 12. DISCUSSION Serum ferritin levels would be preferable to be measured in children and adolescents with insomnia and/or fatigability regardless of psychiatric diagnoses or gender. Iron supplementation can improve the hypoferritinemia-related psychological symptoms of children and adolescents, such as poor concentration, anxiety, depression, low energy and/or irritability.

Abstract
With intensive training, bone injuries are a major concern for athletes. To assess bone condition, we often measure bone turnover markers, bone mineral content and density; however, in junior athletes, it is not easy to distinguish changes caused by bone injuries from those caused by growth, because the metabolism is increased in both cases. Moreover, although some studies have examined female endurance athletes, knowledge regarding changes in static and dynamic bone conditions in late teen athletes is limited. In this study, we measured the bone mineral content and density, as well as bone turnover markers, in 40 elite female sprinters in their late teens. Whole body mode dual-energy X-ray absorptiometry was performed to measure bone mineral content and density. Blood samples were collected to determine bone resorption and formation markers at the end of track season in 2016 and during the same period of the following year. Body weight and bone mineral content significantly increased, and tartrate-resistant acid phosphatase type 5b, bone-type alkaline phosphatase, and osteocalcin significantly decreased after a year. Furthermore, the rate of change in bone mineral content was higher in younger athletes, indicating that bone growth approaches completion in the late teen years and that bone metabolism accordingly decreases.

Abstract
INTRODUCTION The current study sought to compare the treatment continuation rates of asenapine and brexpiprazole while specifically investigating the factors influencing this index and the clinical efficacy of brexpiprazole. METHODS Retrospective study on patients with schizophrenia who were prescribed either asenapine (n = 73) or brexpiprazole (n = 136), as part of their routine medical care. RESULTS The treatment continuation rates for asenapine and brexpiprazole were 19.0% and 38.6% at 52 weeks, with that of brexpiprazole found to be significantly higher than that of asenapine (p = .002). Moreover, age was found to be a significant factor affecting the treatment continuation rate for brexpiprazole (p = .03). Additionally, patients with a longer continuation duration had significantly lower Clinical Global Impression-Severity of Illness (CGI-S) scale scores compared to those who discontinued early (p = .04). The continuation rate was also significantly higher for those who began using the drug as outpatients compared to those first administered the drug as inpatients (p = .04). Furthermore, disease duration, CGI-S scale, and continuation duration significantly affected the clinical efficacy of brexipiprazole (p < .05 for all). CONCLUSIONS The continuation rate for brexpiprazole increases as the age of the patient increases, as disease severity decreases, and if the patient first uses the drug as an outpatient. Shorter disease duration and longer drug administration may lead to improved clinical efficacy. These results suggest that brexpiprazole is an effective treatment option for maintenance therapy of schizophrenia.

Abstract
BACKGROUND/AIM Eicosapentaenoic acid (EPA) is an unsaturated fatty acid with various bioactivities, including antitumor effects. We previously reported a synergistic antitumor effect of cisplatin (CDDP) and EPA. Here, we examined the underlying mechanism. MATERIALS AND METHODS The human oesophageal cancer cell line TE-1 was treated with the combination of EPA and CDDP. Nuclear translocation of NF-κB, a transcription factor involved in cytokine production, was detected by immunohistochemistry. IL-6 levels were measured by ELISA. Apoptosis and cell cycle distribution were evaluated by flow cytometry. RESULTS Nuclear translocation of NF-κB in TE-1 cells was synergistically decreased by CDDP and EPA. IL-6 production was increased following treatment with CDDP, but treatment with EPA decreased IL-6 levels. Apoptosis was synergistically induced by CDDP and EPA. A G2/M cell cycle arrest was observed with the combination of CDDP and 150 μM EPA, and S phase arrest with the combination of CDDP and 100 μM EPA. CONCLUSION The combination of CDDP and EPA synergistically suppresses NF-κB nuclear translocation and increases apoptosis by inducing cell cycle arrest at the S or G2/M phase.

Abstract
The effectiveness and safety of antipsychotics have not been fully established in children and adolescents. Many antipsychotics approved for use in adults are prescribed off-label to children and adolescents. We investigated the effectiveness and tolerability of antipsychotics for children and adolescents with schizophrenia and bipolar disorder. A literature review of the empirical evidence regarding the use of antipsychotics, particularly second-generation antipsychotics, in children and adolescents showed that these drugs were safe and effective for this population. Antipsychotics were similarly effective for treatment of schizophrenia and bipolar disorder in children and adolescents. When prescribing antipsychotics to this population, clinicians should consider adverse events and the discontinuation rate in treated patients. However, the current evidence shows a lack of consensus regarding the use of antipsychotics in children and adolescents.

Abstract
Estrogen deficiency can be caused by ovarian dysfunction in females. Mechanisms underlying osteoporosis in this condition have been characterized in animal models, such as ovariectomized mice and rats, although it remains unclear how hypothalamic dysfunction promotes osteoporosis. Here, we show that administration of a gonadotropin-releasing hormone antagonist (GnRHa) significantly decreases uterine weight, a manifestation of hypothalamic dysfunction, and promotes both cortical and trabecular bone loss in female mice in vivo. We also report that osteoclast number significantly increased in mice administered GnRHa, and that the transcription factor hypoxia inducible factor 1 alpha (HIF1α) accumulated in those osteoclasts. We previously reported that treatment of mice with the active vitamin D analogue ED71, also known as eldecalcitol, inhibited HIF1α accumulation in osteoclasts. We show here that in mice, co-administration of ED71 with GnRHa significantly rescued the reduced cortical and trabecular bone mass promoted by GnRHa administration alone. GnRHa-dependent HIF1α accumulation in osteoclasts was also blocked by co-administration of ED71. We conclude that hypothalamic dysfunction promotes HIF1α accumulation in osteoclasts and likely results in reduced bone mass. We conclude that treatment with ED71 could serve as a therapeutic option to counter osteoporotic conditions in humans.

Abstract
Low energy availability in female athletes often causes hypothalamic amenorrhea and osteoporosis, in turn promoting stress fractures. Mechanisms underlying these conditions remain unclear. Here we show that model mice subjected to food restriction (FR) or FR-plus-voluntary running exercise exhibit significantly reduced bone mineral density, cortical bone parameters and uterine weight than do control mice, and that these parameters worsen in the FR-plus-exercise group. Relative to controls, FR and FR-plus-exercise groups showed significantly lower mineral apposition rate and osteoclast number and significantly reduced serum insulin-like growth factor-1 (IGF1) levels. Outcomes were rescued by ED71 or 1.25(OH)2D3 treatment. Thus, we conclude that administration of active vitamin D analogues represents a possible treatment to prevent these conditions.

Abstract
Background Gastric inflammatory fibroid polyp (IFP) is a rare polypoid lesion of the stomach that is characterized pathologically by the presence of spindle cells, a prominent network of blood vessels, and inflammatory infiltration of eosinophils. IFP is mainly located in the gastric antrum and is usually semi-pedunculated and covered with normal mucosa. There have been several reports of large IFPs with ulceration on the surface, at the apex, but no report of the IFP with ulceration at the fornix of the stomach. We report a case of IFP with ulceration that was suggested to be gastric cancer and was resected for diagnostic treatment. Case presentation A 79-year-old woman presented to our hospital. During mass screening for cancer, stomach fluoroscopy revealed an abnormal shadow. Endoscopy showed an ulcerated tumor at the fornix of stomach; hence, gastric cancer was suggested because of the polypoid lesion with irregular ridges and ulceration. Pathological diagnosis of gastric biopsy specimens revealed an inflammation of the gastric mucosa, and specific findings for gastric cancer were not obtained. Because we could not exclude gastric malignancies such as cancer or gastrointestinal stromal tumor, we performed a partial resection of the stomach with a 2-cm margin using the laparoscopic-assisted method. Pathological examination of the resected specimen revealed that the tumor was present in the submucosal layer and consisted of collagen fiber containing inflammatory cell infiltration of mainly eosinophils. A prominent network of blood vessels was also found in the specimens. Immunohistochemical staining revealed mild positivity for CD34, and α-SMA and was negative for c-kit, DOG-1, s-100, desmin, ALK, and IgG4. The lesion was thus diagnosed as an IFP. The postoperative course was uneventful. The patient is currently asymptomatic and has shown no recurrence. Conclusion IFPs have variable locational, morphological, histological, pathological, and immunohistochemical features. We reported that the gastric IFP was located at the fornix of the stomach and was similar in morphology to gastric cancer. This case is clinically significant to avoid over-surgery.

Abstract
Abstract
Background/Introduction
Acute heart failure (AHF) is one of the major causes of mortality, and identifying the patients at high risk of mortality at the time of admission is crucial to improve clinical outcomes. Although some risk prediction models for patients with AHF have been proposed mainly from randomized clinical trials, the patients in such studies tend not to be similar to those in the real world. Recently, BIOSTAT risk score and AHEAD score derived from two large-scale registry dataset are proposed as useful risk stratification tools for patients with AHF. However, these scores have not been well externally validated and their prognostic prediction performance has not been directly compared.
Purpose
To validate and compare prognostication of BIOSTAT risk score and AHEAD score in AHF patients.
Methods
Patients who consecutively admitted to the cardiac intensive-care unit in our institution with a diagnosis of AHF from 2007 to 2011 were analyzed. Among them, patients with acute coronary syndrome, dialysis, malignancy were excluded. BIOSTAT risk score was calculated using 5 factors (age, blood urea nitrogen, BNP, hemoglobin, prescription of beta blockers), and AHEAD score was also calculated with 5 factors (atrial fibrillation, hemoglobin, age, creatinine, and diabetes mellitus). We also developed AHEAD + BNP model incorporating BNP into AHEAD score. Endpoint was 1-year all-cause death.
Results
Overall, 591 eligible patients were enrolled (mean age was 70±14 years old, 64.8% were male) and 96 patients (16.2%) died during the follow-up of 1-year. The median [interquartile range] of AHEAD score and BIOSTAT risk score were 2 [1–3] and 3 [2–4], respectively. The areas under the curves of receiver operating characteristic curve (AUC) were 0.66 for AHEAD, 0.68 for AHEAD + BNP, and 0.72 for BIOSTAT, respectively. The calibration plots for AHEAD, AHEAD + BNP, and BIOSTAT models showed good calibration (Hosmer-Lemeshow test: p=0.89, 0.74, and 0.74, respectively). The BIOSTAT model's AUC was significantly higher compared to AHEAD (p=0.018) and marginally statistically higher compared to AHEAD + BNP (p=0.054). However, BIOSTAT model showed statistically significant net reclassification improvement compared to both AHEAD (NRI: 0.43, p<0.001) and AHEAD + BNP (NRI: 0.43, p<0.001).
Conclusion
The BIOSTAT score comprised of five readily available clinical variables predict 1-year mortality of patients with AHF with good discrimination and calibration.

Abstract
Abstract
Background
Orsiro ultrathin-strut bioresorbable-polymer sirolimus-eluting stent (BP-SES) might facilitate early vascular healing responses that seems to be associated with improved long-term clinical outcomes. We compared the early vascular healing responses to BP-SES and Xience durable-polymer everolimus-eluting stent (DP-EES) in patients with chronic coronary syndrome (CCS) using optical coherence tomography (OCT).
Methods
A total of 40 patients with CCS receiving OCT-guided PCI were included. 20 patients were assigned to BP-SES, and 20 to DP-EES. OCT was performed immediately after stent placement (post-procedure) and at 1 month follow-up. Struts were recorded as uncovered if any part was visibly exposed in the lumen or covered if a layer of tissue covered all reflecting surfaces. The incidence of intrastent thrombus (IS-Th) and irregular protrusion (IRP) were also assessed.
Results
At 1 month, the percentage of uncovered struts was significantly lower in the BP-SES compared with the DP-EES (2.8±1.6% vs. 5.8±1.8%, respectively; p<0.001), and that of malapposed struts was similar between both groups (2.5±3.1% vs. 2.4±2.2%; p=0.76). There were no differences in the incidence of IS-Th (65.0% vs. 55.0% at post-procedure; p=0.54, 30.0% vs. 35.0% at 1 month; p=0.75) and IRP (30.0% vs. 25.0% at post-procedure; p=0.74). IRP had completely resolved at 1 month in both groups.
Conclusion
Early vascular healing response to Orsiro BP-SES implantation was revealed in CCS patients at 1 month compared with Xience DP-EES. Orsiro BP-SES may have a potential to shorten the dual antiplatelet therapy duration.

Abstract
Abstract
Background
Recent clinical study suggests newer-generation drug-eluting stents (DES) that combine ultrathin strut and nano-coating with biodegradable polymers sirolimus-eluting stent (BP-SES) could improve long-term clinical outcomes in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) over current generation DES. However, safety profiles in very early phase have not been systematically addressed.
Objective and method
We exploratory investigate early vascular response following BP-SES implantation in patients with STEMI to reveal mechanism of the favorable clinical outcomes in recent studies using frequency domain-optical coherence tomography (FD-OCT).
Consecutive twenty patients with STEMI who underwent FD-OCT immediately after primary PCI and were eligible for follow-up FD-OCT at 2 weeks after implantation were enrolled between June 2018 and November 2019.
Results
Twenty patients (age 62.7±11.3 years, male 85.0%) were enrolled with frequencies of hypertension (45.0%), diabetes mellitus (35.0%), dyslipidemia (55.0%) and smoking (80.0%). Aspiration catheter were used in all patients, and 1.13±0.34 stents were used. Only one patient (5.0%) received chronic antiplatelet therapy with aspirin prior to the onset of STEMI. All patients started to receive prasugrel as thienopyridine from this event and continued dual antiplatelet therapy for 2 weeks.
The percentage of uncovered struts significantly decreased from post-procedure to 2W follow-up (69±18% post-procedure versus 30±11% at 2W follow up, p<0.0001). Malapposed struts also decreased (5.6±5.7% post-procedure versus0.9±1.2% at 2W follow up, p<0.0001).The average protrusion area of athero-thrombotic burden numerically decreased (0.37±0.19 at post-procedure versus 0.34±0.14 mm2 at 2W follow up, p=0.19) and its volume showed similar tendency (10.60±6.40 at post-procedure versus 9.36±5.14 mm3 at 2W follow up, p=0.19).
Conclusion(s)
This study firstly elucidated very early vascular responses following ultrathin strut BP-SES implantation in STEMI patients, showing early progression of strut coverage and resolution of athero-thrombotic materials. This technology may have a potential to overcome the current generation DESs in this clinical setting.

Abstract
Autism Spectrum Disorder (ASD) has been linked with risk of suicide, and several cases of suicide attempts by adolescents with ASD have been reported. However, there is scant research on therapeutic approaches to prevent suicide re-attempts by children with ASD who have already attempted suicide. We report our experience of treating an 11-year-old girl with adjustment disorder comorbid with ASD who was transported to our hospital after sustaining injuries from the suicide leap. Initially, she was diagnosed with adjustment disorder brought on by poor interpersonal relationships at school, and, upon reviewing the patient's personal history, her underlying ASD characteristics became apparent. To prevent a re-attempt, it was crucial to reduce her risk factors and enhance her protective factors. To reduce her risk factors, we manipulated the environmental factor that triggered the patient's suicide attempt. In addition, to reinforce her protective factors, we intervened in the parent-child relationship and addressed her hesitation to ask for help, which we identified as a predisposing factor since early childhood. Over the course of her treatment, she did not exhibit suicidal ideation or re-attempt suicide.

Abstract
UNLABELLED We hypothesized that the baseline FRAX score and previous falls would predict the incidence of sarcopenia in community-dwelling older adults who received medical check-ups. The FRAX score (hazard ratio [HR] = 1.087, 95% CI 1.014-1.167) and previous falls (HR = 5.181, 95% CI 1.002-26.777) were determined to be independent risk factors for the incidence of sarcopenia. PURPOSE This prospective study was performed to elucidate the prevalence and incidence of sarcopenia in community-dwelling older adults who received medical check-ups, and to determine whether FRAX score and fall history predict the incidence of sarcopenia. METHODS Participants were recruited from a group of individuals who had registered for an annual town-sponsored medical check-up. Study inclusion criteria were aged older than 60 years, living independently, and ability to walk without assistance. Individuals who received nursing care were excluded from the study. A total of 426 residential participants were analyzed. Demographic information, fall history of the previous year, and FRAX score without bone mineral density were assessed. The assessment for sarcopenia was based on the recommendations of the Asian Working Group for Sarcopenia. RESULTS The final sample for the assessment of sarcopenia incidence comprised 258 participants. The mean follow-up time was 2.92 years. The rate of sarcopenia was 1.06 cases per 100 person-years at risk. The Cox multivariate logistic regression model in our analysis was adjusted for age, gender, muscle mass, and covariates and showed that the FRAX score (HR = 1.087, 95% CI 1.014-1.167) and recent history of falls (HR = 5.181, 95% CI 1.002-26.777) were independent risk factors for the incidence of sarcopenia. CONCLUSION FRAX and history of falling can be a simple screening tool to raise awareness of the prevention of osteoporosis and sarcopenia in clinical settings.

Abstract
BACKGROUND/AIM Eicosapentaenoic acid (EPA) inhibits NF-ĸB activation and IL-6 production in TE-1 esophageal cancer cells. NF-ĸB is related to cancer cell migration. The aim of this study is to evaluate whether EPA has a metastasis suppressing effect. Herein, we investigated EPA-treated TE-1 cell migration using TAXIScan. MATERIALS AND METHODS EZ-TAXIScan® was used to verify whether EPA inhibits cancer cell chemotaxis. RESULTS Using 50% fetal bovine serum (chemoattractant) without EPA (positive control), average velocity was 0.306±0.084 μm/min compared to 0.162±0.067 μm/min without chemoattraction (negative control). Directionalities of positive and negative controls were 1.039±0.152 and 0.488±0.251 radians, respectively, indicating a significant increase in migration of the positive control compared to that of the negative control. Average velocities were 0.306±0.084 (no EPA), 0.288±0.078 (100 μM EPA), and 0.240±0.054 200 μM (EPA) μm/min, indicating that EPA reduced velocity dose-dependently. Average directionalities were 1.039±0.152 (no EPA), 0.967±0.164 (100 μM EPA), and 0.901±0.146 (200 μM EPA) radians, indicating that EPA also inhibited directionality dose-dependently. CONCLUSION EPA suppresses directional migration of TE-1 cells.

Abstract
Many elite female athletes struggle to maintain performance while transitioning from high school to university-level (senior) sports. This study explores factors of body composition that influenced performance in elite junior female track and field athletes transitioning to the senior division. Forty-two elite female track and field athletes, ranked among the top 100 in Japan, were enrolled in this study. Whole-body mode dual-energy X-ray absorptiometry scans were performed during the post-season of 2016 and 2017. Athletes’ performances were assessed using the International Association of Athletics Federation scoring system. Relationships between changes in performance and those in body composition were investigated. There were significant negative correlations between changes in performance and fat mass (FM), and percentage FM (FM%). This was seen in total body and lower extremities, and not in the trunk and upper extremities. In addition, there was a positive correlation between changes in performance and percentage lean mass (LM%). However, there were no correlations between changes in performance and LM and total mass. Elite female track and field athletes transitioning to senior division should decrease their FM and FM% and increase LM%, to sustain or improve performance. It is also more important to monitor changes in body composition than body mass.

Abstract
The condition of periodic psychosis of adolescence based on the clinical features of recurrent depressive symptoms, sub-stupor, and psychotic symptoms whose features return to a normal state within 2 weeks with no residual symptoms has been often seen during adolescence. However, international recognition of periodic psychosis of adolescence is low and the condition is not recognized as an independent disease in ICD-10 or DSM-5. We presented a case report of a depressive episode central to periodic psychosis of adolescence in a 16-year old female. The symptoms presented in the case correspond to the DSM-5 classification of premenstrual dysphoric disorder. However, a diagnosis of periodic psychosis of adolescence was made due to the presence of clinical features of victim mentality, increased irritability, suicidal ideations, and changes in consciousness over short periods of time and sub-stupor. This report was focused on the medical treatment of the episode of periodic psychosis of adolescence with the aim of verifying its current significance.

Abstract
Background:
Few studies on gender-based diagnostic characteristics of adolescent
suicide attempters in emergency departments (EDs) have included individuals with
autism spectrum disorder (ASD).
Objective:
This study aimed to examine the clinical features of adolescent suicide attempts in
EDs, focusing on gender differences and considering individuals with ASD.
Method:
Ninety-four adolescent patients, aged less than 20 years, who had attempted suicide
and had been hospitalized in an emergency department, participated in this study. Psychiatric
diagnoses according to DSM-IV criteria and clinical features were compared between
male and female patients.
Results:
The number (%) of males was 15 (16.0), and that of females was 79 (84.0). The mean
age (SD) of males was 17.1 (1.5), and that of females was 16.9 (1.6). The attempt methods
were more serious, length of stay in the emergency room longer, and rate of outpatient treatment
lower in males. In addition, suicide attempters with ASD were significantly more frequent
in male. Adjusting for age and gender, adjustment disorder was significantly associated with
the presence of suicide attempters with ASD using a multivariable logistic regression.
Conclusion:
Males were less likely to visit psychiatric service previous to attempting suicides,
and may be likely to complete suicides. In addition, suicide attempters with ASD are
characteristic in male, and likely to have comorbid adjustment disorder. ED visits offer a
window of opportunity to provide suicide prevention interventions for adolescents, and
therefore, psychiatrists in EDs have a crucial role as gatekeepers of preventing suicide reattempts,
especially in adolescent males including individuals with ASD having adjustment
disorder.
