Abstract
BACKGROUND Adenoma detection rate (ADR) is an important indicator of colonoscopy quality and colorectal cancer incidence. Both linked-color imaging (LCI) with artificial intelligence (LCA) and LCI alone increase adenoma detection during colonoscopy, although it remains unclear whether one modality is superior. This study compared ADR between LCA and LCI alone, including according to endoscopists' experience (experts and trainees) and polyp size. METHODS Patients undergoing colonoscopy for positive fecal immunochemical tests, follow-up of colon polyps, and abdominal symptoms at a single institution were randomly assigned to the LCA or LCI group. ADR, adenoma per colonoscopy (APC), cecal intubation time, withdrawal time, number of adenomas per location, and adenoma size were compared. RESULTS The LCA (n=400) and LCI (n=400) groups showed comparable cecal intubation and withdrawal times. The LCA group showed a significantly higher ADR (58.8% vs. 43.5%; P<0.001) and mean (95%CI) APC (1.31 [1.15 to 1.47] vs. 0.94 [0.80 to 1.07]; P<0.001), particularly in the ascending colon (0.30 [0.24 to 0.36] vs. 0.20 [0.15 to 0.25]; P=0.02). Total number of nonpolypoid-type adenomas was also significantly higher in the LCA group (0.15 [0.09 to 0.20] vs. 0.08 [0.05 to 0.10]; P=0.02). Small polyps (≤5, 6-9mm) were detected significantly more frequently in the LCA group (0.75 [0.64 to 0.86] vs. 0.48 [0.40 to 0.57], P<0.001 and 0.34 [0.26 to 0.41] vs. 0.24 [0.18 to 0.29], P=0.04, respectively). In both groups, ADR was not significantly different between experts and trainees. CONCLUSIONS LCA was significantly superior to LCI alone in terms of ADR.

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
Revised idiopathic pulmonary fibrosis treatment guidelines were published in 2015, and nintedanib was conditionally recommended. Although diarrhea is reported to be a common major adverse event associated with nintedanib, there have been few reports on detailed endoscopic findings of nintedanib-associated enterocolitis. A 74-year-old woman was diagnosed with idiopathic pulmonary fibrosis 4 years ago in May. She was started on nintedanib (300 mg). Three months later, hepatic dysfunction was observed; therefore, the drug was temporarily discontinued and then resumed at a dose reduction of 200 mg. Five months later, the patient developed diarrhea, and the dose was reduced to 150 mg. However, no effect was noted; hence, colonoscopy was performed. Various inflammatory lesions, such as erythema and erosions, were observed continuously at the rectum, which resembled ulcerative colitis. No improvement was observed 2 months after follow-up colonoscopy, and nintedanib-related enterocolitis was suspected. The dose was further reduced to 100 mg. Since the endoscopic findings of nintedanib-associated enterocolitis are similar to those of ulcerative colitis, it is critical to consider patients with diarrhea who are taking nintedanib as having associated enterocolitis and attempt to reduce or discontinue the drug if diarrhea does not improve with antidiarrheal agents.

Abstract
Pneumatosis cystoides intestinalis is an uncommon disease that rarely causes intussusception. We report the case of a 16-year-old male patient with intermittent abdominal pain who was diagnosed with intussusception. The patient had no history of raw food ingestion, fever, diarrhea, or hematochezia. Computed tomography revealed intussusception characterized by a crab-finger appearance, and pneumatosis cystoides intestinalis was diagnosed by colonoscopy. Treatment with hyperbaric enema and low-flow oxygen therapy resulted in a prominent improvement of the lesion. No recurrence was observed for > 1 year. Intermittent abdominal pain without diarrhea or hematochezia in male adolescents may represent pneumatosis cystoid-related intussusception, and the addition of low-flow oxygen therapy may help avoid surgery.

Abstract
Background Return-to-sports (RTS) rates after anterior cruciate ligament (ACL) reconstruction (ACLR) differ according to the level at which patients return. It is unclear whether the level of RTS is affected by psychological readiness to return. Purpose To examine the association between psychological readiness to RTS and subjective RTS level 12 months after ACLR. Study Design Case-control study; Level of evidence, 3. Methods A total of 47 patients who underwent unilateral primary ACLR surgery were enrolled. Assessments at 6 and 12 months postoperatively consisted of knee strength testing (isokinetic quadriceps and hamstring strength), the International Knee Documentation Committee Subjective Knee Evaluation Form (IKDC-SKF), and the Anterior Cruciate Ligament-Return to Sport after Injury (ACL-RSI) scale to measure psychological readiness to RTS. Patients were assigned to 1 of 3 subgroups based on their subjective assessment of RTS level at 12 months postoperatively: RTS at or above preinjury level (RTS≥Pre; n = 19), RTS below preinjury level (RTS Results Significant differences were found among the RTS≥Pre, RTS Conclusion The ACL-RSI score was significantly different among the study groups, and the ACL-RSI score at 12 months postoperatively and younger age were associated with RTS at or above preinjury level.

Abstract
The scleractinian coral genus Cyphastrea is widely distributed in the Indo-Pacific region and is common from the subtropical to the warm-temperate regions in Japan. Three new species in this genus have recently been reported from south-eastern Australia or the Red Sea. However, taxonomic and species diversity have been little studied so far in Japan. In this study, we analyzed 112 specimens of Cyphastrea collected from the subtropical to the warm-temperate regions in Japan to clarify the species diversity in the country. This analysis was based on skeletal morphological and molecular analyses using three genetic markers of the nuclear 28S rDNA, histone H3 gene, and the mitochondrial noncoding intergenic region between COI and tRNAmet. The molecular phylogenetic trees showed that our specimens are separated mainly into four clades. Considering the morphological data with the molecular phylogenetic relationships, we confirmed a total of nine species, including two species, C. magna and C. salae, recorded for the first time in Japan. Although eight out of nine species were genetically included within Cyphastrea, one species, C. agassizi, was genetically distant from all other species and was closely related to the genus Leptastrea, suggesting the return of this species to the genus to which it was originally ascribed. Two newly recorded species were reciprocally monophyletic, while the other six species (excluding C. agassizi) clustered in two clades without forming species-specific lineages, including three polyphyletic species. Thus, the species boundary between species in Cyphastrea remains unclear in most species using these three sequenced loci.

Abstract
The pathologic diagnosis of duodenal tumors is a developing field; however, its overview remains unclear. We describe a rare case of a duodenal gastric-type neoplasm in a 50-year-old woman. She visited her primary care doctor with complaints of upper abdominal pain, tarry stools, and shortness of breath on exertion. She was admitted owing to a stalked polyp with erosion and hemorrhage in the descending part of the duodenum. Endoscopic mucosal resection (EMR) was performed on the polyp. Histologically, the resected polyp was a lipomatous lesion in the submucosal layer, composed of mature adipose tissues. Scattered irregular lobules of Brunner's gland-like structures with well-preserved construction but mildly enlarged nuclei and occasional conspicuous nucleoli of the constituent cells were observed. The resection margin was negative. EMR findings of the duodenal polyp showed a gastric epithelial tumor within a lipoma, a rare histological type that has not been reported previously. This tumor may be classified as a "neoplasm with uncertain malignant potential" in a lipoma, an intermediate category between adenoma and invasive adenocarcinoma. There is no consensus on treatment, and careful follow-up is recommended. This is the first report of a duodenal gastric-type neoplasm with uncertain malignant potential in a lipoma.

Abstract
BACKGROUND Isometric horizontal abduction loading has been applied to improve imbalanced scapular muscle activities during shoulder exercises; however, the effect on glenohumeral joint muscle activity remains unclear. The purpose of this study was to investigate the changes in electromyographic activity of shoulder muscles during forward flexion with isometric horizontal abduction loading in healthy participants. METHODS Thirteen healthy men were recruited for this study. Participants performed shoulder forward flexion with and without isometric horizontal abduction loading using an elastic band (Flex-band and Normal-flex conditions). Muscle activities were evaluated while maintaining shoulder flexion at 60°, 90°, 120° and 150° (static task) and during active shoulder flexion from 0° to maximum elevation (dynamic task). Surface electrodes were placed on the deltoid, pectoralis major, infraspinatus and teres minor muscles to measure the activities of the shoulder muscles during each task. The muscle activities during the static task were compared using a two-way analysis of variance with repeated measures of the two factors, loading condition and flexion position, and using a paired t-test between the two conditions during the dynamic task (P < 0.05). RESULTS For the static task, the Flex-band significantly increased the deltoid middle and posterior activities by 2-15 times, and infraspinatus and teres minor activities by 2-3 times compared to the Normal-flex at all positions. In contrast, the Flex-band significantly decreased (about half) the deltoid anterior (at 120° and 150°) and pectoralis major (at all positions) activities compared to the Normal-flex. For the dynamic task, the Flex-band significantly increased the deltoid middle, posterior, infraspinatus, and teres minor activities by 2-7 times and decreased the deltoid anterior activity by approximately two-thirds. CONCLUSIONS Applying isometric horizontal abduction loading during shoulder forward flexion may be useful in improving the imbalanced muscle activities of the glenohumeral joint, such as excessive activity of the deltoid anterior and pectoralis major and dysfunction of the deltoid middle, posterior and shoulder external rotator muscles. Shoulder forward flexion with horizontal abduction loading would be available for exercise in patients with massive rotator cuff tears or after rotator cuff repair and shoulder arthroplasty.

Abstract
The purpose of this study was to clarify the difference in onset timing and incidence of undiagnosed finger symptom (UDFS) between various shoulder surgical procedures. In this study, UDFS symptoms included the following four symptoms in the fingers;edema, limited range-of-motion, skin color changes, and abnormal sensations. UDFS cases were defined as those presenting with at least one UDFS. In result, the incidence rate of UDFS cases was 7.1% overall (58/816 shoulders), 7.4% (32/432) in arthroscopic rotator cuff repair (ARCR), 9.0% (11/122) in open rotator cuff repair (ORCR), 1.4% (2/145) in arthroscopic subacromial decompression (ASD), 13.2% (5/38) in open reduction and internal fixation (ORIF), 11.1% (3/27) in humeral head replacement, 4.8% (1/21) in anatomical total shoulder arthroplasty, and 12.9% (4/31) in reverse total shoulder arthroplasty cases. The Rate was significantly higher with ARCR compared to ASD (p<.01). About onset timing in weeks postoperatively, the ORIF group had a statistically earlier symptom onset than the Rotator cuff repair (ARCR + ORCR) group (2.4 weeks vs. 6.0 weeks, p<.01). When classifying the onset timing into before and after the removal of the abduction pillow, the ORIF group showed a statistically higher rate of onset before brace removal than the Rotator cuff repair groups (p<.01). Differences in UDFS among shoulder surgeries were demonstrated in this study. J. Med. Invest. 70 : 415-422, August, 2023.

Abstract
Several new treatments for ulcerative colitis have been developed recently. The depletion of leukocytes by granulocyte and monocyte adsorption apheresis (GMA) was developed and adapted for patients with ulcerative colitis with rare adverse events. We investigated whether treatment with GMA and prednisolone (GMA + PSL) is more effective than PSL alone for patients with moderate to severe ulcerative colitis. Forty-seven patients with moderate to severe ulcerative colitis were retrospectively analyzed. Among the 47 patients, 27 received PSL, while 20 received GMA + PSL. The clinical activity of ulcerative colitis was evaluated using the Lichtiger clinical activity index (CAI) and serum levels of C-reactive protein. Mayo endoscopic score (MES) was used to examine endoscopic activity. The clinical remission rate was significantly higher in the GMA + PSL group than in the PSL group (65% vs 29.6%, p = 0.0206). The mucosal healing rate was also significantly higher in the GMA + PSL group than in the PSL group (60% vs 26%, p = 0.0343). The combination of GMA and steroids may be more effective than steroids alone for inducing clinical remission and mucosal healing in patients with moderate to severe ulcerative colitis.

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
BACKGROUND Although some tests of shoulder internal rotator strength including subscapularis are commonly used in clinical practice, the differences in shoulder muscle activities other than subscapularis muscle among those tests are not well understood. The purpose of this study was to examine the activities of the superficial shoulder muscles in addition to internal rotation strength during two belly-press and three lift-off test positions. METHODS Thirteen healthy young adult men (age 29.5 ± 5.4 years) were recruited for the present study. They performed isometric shoulder internal rotation against manual resistance during the belly-press test positions with two different resistance locations and the lift-off test with three different arm positions. The surface electromyographic activities of the superficial shoulder muscles, including the deltoid (anterior, middle, posterior), pectoralis major, long head of triceps and latissimus dorsi muscle, were collected and compared between the two belly-press tests, and among the three lift-off test positions (P < 0.05). RESULTS The belly-press test position with resistance to elbow showed significantly greater activities of the anterior and middle deltoid muscle than the original belly-press test; but showed significantly smaller activities of pectoralis major, triceps and latissimus dorsi muscle than the original belly-press test. Among the three lift-off tests, all muscle activities, except for the pectoralis major, were greater in the lift-off at L4/5 than in the lift-off at buttock and thigh. Lift-off at thigh showed significantly smaller activity of pectoralis major than the lift-off at L4/5 and buttock. CONCLUSIONS The findings of the present study suggest that clinician should give attention to compensatory motions by excessive shoulder extensor and adductor muscle activities for the original belly press test, by excessive deltoid muscle activities for the modified belly-press, and by excessive shoulder extensor muscle activities for the lift off test in the inferior arm positions.

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
This study aims to compare the limb symmetry index (LSI) of the rate of torque development (RTD) of the quadriceps with that of the peak torque after anterior cruciate ligament reconstruction (ACLR) using semitendinosus and gracilis tendon (STG) autografts and to investigate the associations of the LSI of torque parameters with patient-reported knee function. The participants included 23 female athletes after ACLR with STG grafts. Isometric quadriceps tests were performed using an isokinetic dynamometer. The peak torque, RTD100 (0 to 100 ms) and RTD200 (100 to 200 ms) were determined using torque-time curves. Comparisons of the LSI of torque parameters was performed by ANOVA. Univariate regression analysis was used to examine the relationship between the LSI of torque parameters and the patient-reported knee function. The LSIs of the peak torque and RTD200 were significantly lower than that of the RTD100 (p = 0.049, p = 0.039, respectively). Regression analysis showed that the LSI of the peak torque was associated with the patient-reported knee function (R2 = 0.40, p = 0.001). It would be useful to evaluate the peak torque in young female athletes under the age of 18 and at 8-10 months after ACLR with STG grafts.

Abstract
OBJECTIVES To investigate the knee flexor torque-angle curve after hamstring strain injury using different muscle action types and angular velocities. DESIGN Cross-sectional. SETTING Controlled laboratory. PARTICIPANTS Thirteen collegiate athletes injured hamstring strain (21.0 ± 0.8 years; 173.9 ± 6.5 cm; 70.1 ± 10.5 kg). MAIN OUTCOME MEASURES Concentric and eccentric knee flexor torque was measured at 60 & 300°/sec. Peak torque and average torque every 10° were determined from torque-angle curve and injured side was compared with non-injured side. RESULTS No significant differences were found in the concentric muscle actions. However, the eccentric peak torque was significantly lower on the injured side at 60°/sec (p = 0.048) and at 300°/sec (p = 0.002). The average eccentric torque was significantly lower on the injured side at 60°/sec from 10° to 20° of knee flexion (p = 0.012-0.018) and at 300°/sec from 10° to 60° of knee flexion (p = 0.005-0.049). CONCLUSION The knee flexor torque-angle curve changes with eccentric muscle action after hamstring injury. Eccentric torque declines were close to full knee extension at 60°/sec and a wide range of knee flexion at 300°/sec. The assessment and rehabilitation of eccentric hamstring strength may be important to consider the effect of the angular velocity after hamstring strain injury.

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
This study investigated the relationship between quadriceps strength and knee kinematics during a drop vertical jump (DVJ) at 6, 9 and 12 months after anterior cruciate ligament reconstruction (ACLR) in 9 male and 22 female athletes (16.6 ± 2.1 years old). Isokinetic quadriceps strength was measured by a dynamometer (Biodex System 3). Knee flexion excursion was assessed using two-dimensional analysis. Knee flexion excursion at 6 months was significantly smaller in the involved limb than in the uninvolved limb independent of quadriceps strength (56.7° ± 9.3°, 63.4° ± 11.4°, P < 0.001). At 9 months, only the low quadriceps strength group demonstrated a similar interlimb difference (57.2°± 12.3°, 63.3° ± 10.5°, P < 0.001). At 12 months, there was no significant interlimb difference in knee flexion excursion regardless of quadriceps strength. These findings indicate that restoration in symmetrical knee flexion excursion during a DVJ requires rehabilitation as well as quadriceps strength.

Abstract
Aim Although decreased level of consciousness (DLOC) while driving may lead to serious accidents involving drivers and people around them, including passengers and pedestrians, few studies have assessed traffic injuries attributable to preceding DLOC. We aimed to identify factors suggestive of a DLOC preceding traffic injury during initial examination. Methods This study included 193 drivers who were brought to our facility during the 1‐year period from January to December 2018. The drivers were divided into those with and without DLOC for comparison and analysis. Data on age, sex, causes of DLOC, and medical history were retrospectively reviewed from medical records. Results Of these 193 drivers, 58 (30.1%) had experienced preceding DLOC. The following factors suggested possible episodes of preceding DLOC: a single‐vehicle accident (odds ratio [OR] 3.59; 95% confidence interval [CI] 1.76–7.34; P < 0.001) and histories of hypertension (OR 2.64; 95% CI 1.13–6.15; P = 0.0248) and psychiatric disorders (OR 3.49; 95% CI 1.08–11.3; P = 0.0370). The causes of DLOC were endogenous diseases in 20 drivers (34.3%), dozing off episodes in 19 (32.8%), and acute alcohol intoxication in 11 (19.0%). Conclusion Before traffic accidents, 30.1% of drivers experienced DLOC. Single‐vehicle accidents and histories of hypertension and psychiatric disorders were factors suggestive of preceding DLOC.

Abstract
Background Knee osteoarthritis (OA) negatively affects dynamic postural control, which is a basic function that individuals use to perform activities of daily living (ADL). The purpose of this study was to investigate the associations of center of pressure (COP) control during the transition from double-leg to single-leg standing with subjective assessments of ADL and quality of life (QOL) in patients with knee OA. Methods Thirty-six patients (29 females) with moderate-to-severe knee OA participated. Dynamic postural control was evaluated during the transition from double-leg to single-leg standing. Each patient stood on a force plate, lifted the less affected limb as fast as possible, and maintained single-leg standing with the more affected limb. The COP movements corresponding to anticipatory postural adjustment (APA) and transitional phases were assessed. The maximum displacement and peak velocity of the COP movements in the medial–lateral direction were calculated. The Knee Injury and Osteoarthritis Outcome Score (KOOS) was used for the subjective assessment of ADL and QOL. Pearson’s product correlation analysis was performed to investigate the associations of COP movements in the APA and transitional phases with KOOS-ADL and KOOS-QOL. Results In the APA phase, the maximum COP displacement was significantly correlated with KOOS-ADL (r = -0.353, P = 0.035) and KOOS-QOL (r = -0.379, P = 0.023). In the transitional phase, the maximum COP displacement and peak COP velocity were significantly correlated with KOOS-ADL (maximum displacement: r = 0.352, P = 0.035; peak velocity: r = 0.438, P = 0.008) and with KOOS-QOL (maximum displacement: r = 0.357, P = 0.032; peak velocity: r = 0.343, P = 0.040). Conclusions The present study showed that smaller COP movements in the APA phase and smaller and slower COP movements in the transitional phase correlated with poorer ADL and QOL conditions in patients with knee OA. These findings suggest that poor dynamic postural control is associated with poor ADL and QOL conditions in patients with moderate-to-severe medial knee OA. Conservative treatment for patients with knee OA may need to focus on dynamic postural control during the transition from double-leg to single-leg standing.

Abstract
A 38-year-old man was pressed on his trunk by a heavy object weighing about 100 kg. The patient was in shock status on arrival to the hospital. Circular collapse progressed rapidly during contrast computed tomography (CT) scanning. CT images revealed exacerbation of the right lateral deviation of the heart that was earlier seen on X-ray imaging. Considering cardiac herniation based on CT findings, we immediately performed resuscitative thoracotomy and clamshell thoracotomy at the emergency department. Intraoperative findings showed a pericardial defect, and the heart had deviated to the right thoracic cavity. Immediate repositioning revealed a marked improvement in circulation. Full-thickness cardiac injury was observed in the anterior wall of the left ventricle; no active bleeding was observed. We performed temporary thoracic wall closure after cardiorraphy for damage control. After admission to the intensive care unit, he presented with respiratory failure associated with pulmonary contusion. Therefore, veno-venous extracorporeal membrane oxygenation (V-V ECMO) was used from the 2nd to the 5th hospital day. After confirming no intra-thoracic events on the 6th hospital day, chest wall closure was performed. The patient subsequently developed heart failure and mitral regurgitation associated with papillary muscle rupture. On the 62nd hospital day, he underwent mitral annuloplasty at the cardiovascular surgery division; After rehabilitation till 152nd hospital day, he was discharged without any neurological abnormality. This was an extremely rare case with concomitant full-thickness myocardial injury, intracardiac injury, and cardiac herniation. Rapid resuscitative thoracotomy and damage control including V-V ECMO yielded good results. Retrospectively, cardiac herniation should have been suspected earlier basis this observation. Our report highlights that cardiac herniation should be considered in case of cardiac shadow aberrations in cases of blunt chest trauma, familiarity with condition and its characteristic imaging findings are critical for the doctor overseeing initial trauma treatment.

Abstract
BACKGROUND Ventilator weaning protocols are commonly implemented for patients receiving mechanical ventilation. However, the rate of extubation failure remains high despite the protocols. This study investigated the usefulness and accuracy of ventilator weaning through machine learning to predict successful extubation. METHODS We retrospectively evaluated the data of patients who underwent intubation for respiratory failure and received mechanical ventilation in the intensive care unit (ICU). Data on 57 factors including patient demographics, vital signs, laboratory data, and data from ventilator were extracted. Extubation failure was defined as re-intubation within 72 hours of extubation. For supervised learning, the data were labeled requirement of intubation or not. We used three learning algorithms (Random Forest, XGBoost, and LightGBM) to predict successful extubation. We also analyzed important features and evaluated the area under curve (AUC) and prediction metrics. RESULTS Overall, 13 of the 117 included patients required re-intubation. LightGBM had the highest AUC (0.950), followed by XGBoost (0.946) and Random Forest (0.930). The accuracy, precision, and recall performance were 0.897, 0.910, and 0.909, for Random Forest; 0.910, 0.912, and 0.931 for XGBoost; and 0.927, 0.915, and 0.960 for LightGBM, respectively. The most important feature was the duration of mechanical ventilation followed by the fraction of inspired oxygen, positive end-expiratory pressure, maximum and mean airway pressures, and Glasgow Coma Scale. CONCLUSIONS Machine learning could predict successful extubation among patients on mechanical ventilation in the ICU. LightGBM has the highest overall performance. The duration of mechanical ventilation was the most important feature in all models.

Abstract
BACKGROUND Children who survive traffic accidents, and their parents, may develop post-traumatic stress disorder (PTSD) or related symptoms (depression or anxiety), which can hinder the children's development and the parents' ability to provide effective care. In Japan, the PTSD incidence rate following traffic accidents and its related factors remain unclarified. METHOD Participants were 79 children and 104 parents. The children were aged 3-18 years when injured. From August-December 2015, participants completed a self-reported questionnaire survey that comprised the 15-item Post-traumatic Stress Symptoms for Children and the Japanese version of the Impact of Event Scale-Revised. The children's Injury Severity Score (ISS) was also obtained from their medical records. Correlations, analyses of variance, and multiple regression analyses were conducted. RESULTS Among the children and the parents, 10.2% and 22.1% were deemed to be at high risk of PTSD, respectively. Their stress scores were significantly positively correlated with each other and negatively correlated with children's age at the time of the accident. Parents who witnessed their children's accidents and those whose children were hospitalized were more stressed. Neither the children's nor the parents' risk for PTSD was associated with the ISS and the amount of time since the accident. CONCLUSIONS A system that simultaneously works with children and parents, to support both parties' psychological recovery is required. To ensure psychological care post-injury, it is necessary to evaluate PTSD risk, regardless of injury severity. Implementing preventive and early interventions can prove more valuable than awaiting natural recovery.

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
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 Initial management of severe traumatic brain injury is important and includes treatment decision-making and prediction of prognosis. We examined whether biomarkers at admission could be useful prognostic predictors. We focused on electrolytes and blood glucose, which can be measured easily at any facility and for which results can be obtained promptly, before those of other biomarkers, such as D-dimer. METHODS All trauma patients with head injuries treated at Chiba Hokusoh Hospital between 2014 and 2017 were investigated. Cases of multiple trauma accompanied by fatal trauma, hemorrhagic shock, or cardiopulmonary arrest, and pediatric cases, were excluded from this study. Blood gas data at the initial hospital visit were reviewed retrospectively. A poor outcome was defined as death during hospitalization or a vegetative state due to head injury. Factors related to poor outcomes were analyzed. RESULTS Of the 185 male and 79 female patients studied, 34 had poor outcomes. Poor outcome was significantly correlated with potassium (P = 0.003), glucose (P < 0.001), and glucose-to-potassium ratio (P < 0.001) at arrival. The odds ratio was 4.079 for a glucose-to-potassium ratio of ≥50. CONCLUSIONS We evaluated blood gas data at the initial hospital visit, as these results can be obtained more quickly than those of other biomarkers assessed previously. Serum glucose-to-potassium ratio at admission may be a potential predictor of prognosis for severe traumatic brain injury.

Abstract
INTRODUCTION To increase survival rates of patients with severe trauma from road traffic accidents, Japan launched the D-Call Net (DCN) system, which utilizes advanced automatic collision notification technology to dispatch doctors by helicopter. The DCN system began in November 2015 and, as of October 2019, has dispatched doctors 4 times. CASES Case 1-Canceled because trauma was mild. Case 2-Doctor made contact with 2 patients with moderate trauma 29 minutes earlier than would have occurred conventionally. This was the first case in the world to use automotive engineering data to dispatch a doctor to a patient. Case 3-An accident involving 3 severely injured patients activated DCN, enabling doctor-patient contact 20 minutes earlier than would have been possible conventionally. Case 4-DCN was ineffective. DISCUSSION According to 2008 data from Chiba Prefecture, in accidents where victims sustain severe trauma, the interval from accident occurrence to hospital arrival was 67 minutes, even when doctors were dispatched by air ambulance (Doctor-Heli [DH]). Use of accident information for faster doctor dispatch effectively improved survival rates. An algorithm was developed to use accident information to assess trauma severity (severity probability). DCN dispatches doctors by using data, including information on accident site and severity probability, which are sent to smartphones of doctors, thereby reducing the interval from accident to DH request by approximately 17 minutes. DCN is the first system in the world to use automotive engineering information for faster doctor dispatch to traffic accident sites. The system is crucial for improving survival rates and mitigating the aftereffects of traffic accidents.

Abstract
Background The ‘golden hour’ is a well-known concept, suggesting that shortening time from injury to definitive care is critically important for better outcome of trauma patients. However, there was no established evidence to support it. We aimed to validate the association between time to definitive care and mortality in hemodynamically unstable patients for the current trauma care settings. Methods The data were collected from the Japan Trauma Data Bank between 2006 and 2015. The inclusion criteria were patients with systolic blood pressure (SBP) <90 mm Hg and heart rate (HR) >110 beats/min or SBP <70 mm Hg who underwent definitive care within 4 hours from the onset of injury and survived for more than 4 hours. The outcome measure was in-hospital mortality. We evaluated the relationship between time to definitive care and mortality using the generalized additive model (GAM). Subgroup analysis was also conducted using GAM after dividing the patients into the severe (SBP <70 mm Hg) and moderate (SBP ≥70 mm Hg and <90 mm Hg, and HR >110 beats/min) shock group. Results 1169 patients were enrolled in this study. Of these, 386 (33.0%) died. Median time from injury to definitive care was 137 min. Only 61 patients (5.2%) received definitive care within 60 min. The GAM models demonstrated that mortality remained stable for the early phase, followed by a decrease over time. The severe shock group presented with a paradoxical decline of mortality with time, whereas the moderate shock group had a time-dependent increase in mortality. Discussion We did not observe the association of shorter time to definitive care with a decrease in mortality. However, this was likely an offset result of severe and moderate shock groups. The result indicated that early definitive care could have a positive impact on survival outcome of patients with moderate shock. Level of evidence Level Ⅳ, prognostic study,

Abstract
BACKGROUND Traumatic asphyxia is a major cause of death in fatal crowd disasters, but the relationships between compression site, load magnitude, load time, and medical outcomes are unclear. This study estimated thoracoabdominal compression conditions (load magnitude, load time) that could result in respiratory failure in adults. METHODS Eight load patterns-A (chest load: 0 kg, abdominal load: 10 kg), B (0, 20), C (10, 0), D (10, 10), E (10, 20), F (20, 0), G (20, 10), and H (20, 20)-were applied to 14 healthy women. Blood pressure, heart rate, respiratory rate, SpO2, tidal volume, vital capacity, respiratory phase, and modified Borg dyspnea score were measured over time. Breathing Intolerance Index (BITI) was also calculated. RESULTS Vital capacity decreased in patterns C, D, E, F, G, and H. BITI reached the critical range of ≥0.15 (at which respiratory failure occurs after about 45 min) after 14 min in pattern G and 2 min in pattern H. A vital capacity ≤1.85 L and a modified Borg scale score ≥8.3 corresponded to a BITI of ≥0.15 and were regarded as equivalent to reaching the critical range. Furthermore, change in chest load was positively correlated with BITI when abdominal load remained constant. CONCLUSIONS In women, respiratory failure can occur within 1 h from respiratory muscle fatigue, even when total thoracoabdominal load is only about 60% of body weight. A vital capacity ≤1.85 L and modified Borg scale score ≥8.3 can be regarded as indices for predicting respiratory failure.

Abstract
We previously hypothesized that depressive and manic states may be consecutive presentations of the same underlying neuronal plasticity, and that moderate impairments in neuronal plasticity cause depressive states while further impairment to neuronal plasticity causes manic states. Psychopathological or biological relationships between bipolar disorder and schizophrenia have also been revealed. Therefore, in addition to depressive and manic states, psychosis may also be considered a manifestation resulting from additional impairments to neuronal plasticity. In the present manuscript, we hypothesize that moderate and more severe impairments to neuronal plasticity cause depressive and manic states, respectively, and that more serious impairments to neuronal plasticity cause psychosis. Many studies have suggested that impairments in neuronal plasticity contribute to schizophrenia and other mental disorders with psychotic features, and that the impairment of neuronal plasticity in schizophrenia is more severe than that in bipolar disorder. Therefore, we hypothesize more specifically that impairments in neuronal plasticity may be more severe in the order of the cases featuring psychosis, mania, and depression. This progression notably overlaps with the arrangement of schizophrenia, bipolar disorder, and depressive disorder in the DSM-5. Psychotic symptoms are thought to appear further towards the base of the psychopathological hierarchy than are manic or depressive symptoms. If impairments to neuronal plasticity contribute to this psychopathological hierarchy, as we contest that they do, our hypothesis may serve as a bridge between clinical psychopathology, diagnosis, and biological psychiatry.

Several studies showed that first-line bevacizumab plus chemotherapy for HER2-negative metastatic breast cancer improves progression-free survival and tumor response rate but not overall survival. MERiDiAN trial evaluated plasma vascular endothelial growth factor-A (VEGF-A) prospectively as a predictive biomarker for bevacizumab efficacy in metastatic breast cancer. However, results of this trial do not support using baseline plasma VEGF-A to identify patients benefitting most from bevacizumab. We measured baseline serum VEGF-A level from stored blood samples of metastatic breast cancer patient with treated bevacizumab plus paclitaxel as fist-line and later line therapy, and evaluated a correlation between serum VEGF-A level and efficacy of bevacizumab and prognosis of breast cancer patients tread with bevacizumab, retrospectively.
Patients and methods
We examined blood samples from 57 metastatic breast cancer patients treated with bevacizumab and paclitaxel, after obtaining written informed consent. And, we evaluated a correlation between baseline serum VEGF-A level and time to treatment failure (TTF) and overall survival (OS). We also compared the serum VEGF-A level of response group (CR and PR) and that of non-response group (SD and PD).
Results
Baseline serum level of VEGF-A ranged from 80 to 2079 pg/ml. Cases of treatment line were as follows: first-line, 22 cases (38.6%); second line, 11 cases (19.3%) and third-line and the later line, 24 cases (42.1%). The cutoff identified by ROC curve analysis that was able to differentiate response group and non-response group in first-line setting was 360pg/ml for serum VEGF-A. And, we separated high serum VGEF-A group and low serum VEGF-A group of patients treated with bevacizumab plus paclitaxel.
In patients treated as first line therapy, median TTF was 4.0 months with high serum VGEF-A group versus 5.0 months with low serum VEGF-A group, and median OS was 12 months with high serum VGEF-A group versus 11months with low serum VEGF-A group. There were no significant differences in both TTF and OS in first line setting. In patients treated as second line and later line therapy, median TTF was 2.8 months with high serum VGEF-A group versus 7.1 months with low serum VEGF-A group, and median OS was 6.4 months with high serum VGEF-A group versus 12.7 months with low serum VEGF-A group. The prognosis of high serum VEGF-A group was significantly worse than that of low serum group in both TTF and OS.
The serum VEGF-A level of response group was tend to be higher than that of non-response group in first line setting, and was lower in second and later line setting. However, there were no significant differences.
Conclusion
In this study, serum VEGF-A cannot be a predictor for efficacy of bevacizumab plus paclitaxel as first line therapy for metastatic breast cancer patients. On the other hand, there was a possibility that high serum level of VEGF-A can be a poor prognostic factor in late line therapy setting of bevacizumab.

Abstract
In the solar flare observed on June 3, 2012, high energy gamma-rays and neutrons were observed. The event includes a remarkable feature of a high neutron/gamma-ratio in the secondary particles. We have examined whether this high n/γ-ratio can be explained by simulation. As a result of simulations using the GEANT4 program, the high n/γ-ratio may be reproduced for the case that helium and other heavy ions were dominantly accelerated in the flare.

Abstract
AIMS/INTRODUCTION To assess the associations of working conditions, eating habits and glycemic control among young Japanese workers with type 2 diabetes. MATERIALS AND METHODS This hospital- and clinic-based prospective study included 352 male and 126 female working patients with diabetes aged 20-40 years. Data were obtained from June to July 2012 and June to July 2013. Logistic regression analysis was used to estimate multivariable-adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for suboptimal glycemic control (glycosylated hemoglobin level of ≥7%) obtained from June to July 2013. RESULTS Multivariable logistic regression analysis showed that disease duration of ≥10 years (OR 2.43, 95% CI 1.02-5.80), glycosylated hemoglobin level of ≥7% in 2012 (OR 8.50, 95% CI 4.90-14.80), skipping breakfast and late evening meals (OR 2.50, 95% CI 1.25-5.00) and working ≥60 h/week (OR 2.92, 95% CI 1.16-7.40) were predictive of suboptimal glycemic control in male workers, whereas a glycosylated hemoglobin level of ≥7% in 2012 (OR 17.96, 95% CI 5.93-54.4), oral hyperglycemic agent therapy (OR 12.49, 95% CI 2.75-56.86) and insulin therapy (OR 11.60, 95% CI 2.35-57.63) were predictive of suboptimal glycemic control in female workers. CONCLUSIONS Working ≥60 h/week and habitual skipping breakfast concomitant with late evening meals might affect the ability of young male workers with type 2 diabetes to achieve and maintain glycemic control.
