Abstract
OBJECTIVE Trauma informed care (TIC) is an important approach for people who have experienced trauma. Although psychological first aid (PFA) may be effective training in TIC, no study reported an association between PFA training and TIC. This study aimed to investigate the association between PFA training and attitudes toward TIC among health care professionals in Japan. METHODS Japanese health care professionals were recruited for a survey conducted from May 21 to June 18, 2021. TIC was assessed by the Attitudes Related to Trauma Informed Care Scale 10-item short form (ARTIC-10). A question about PFA training participation was originally developed through discussion among researchers. Univariate and multiple linear regression analyses were used to examine the association between the PFA experience and ARTIC-10. RESULTS In total, 484 (3.6%) health care professionals completed all questions. Among them, 77 (15.9%) had experienced PFA training. Univariate and multiple linear regression analyses showed that PFA experience (B = 0.19, 95% CI: 0.02-0.36, P = 0.03; B = 0.17, 95% CI: 0.01-0.34, P = 0.04) was significantly associated with ARTIC-10. CONCLUSIONS This study was the first to show an association between PFA training and attitudes toward TIC among health care professionals, which was a significant result for future research on PFA training, TIC, and trauma care.

Abstract
OBJECTIVES Translation of the Professional Fulfillment Index (PFI) into Japanese would be more useful than the currently developed scales for appropriately measuring burnout and professional fulfillment in healthcare professionals. This study aimed to develop the Japanese version of the PFI and examine its internal consistency, structural validity, and convergent validity in healthcare professionals. METHODS Healthcare professionals in Japan were recruited online. The survey was conducted from October to November 2022. Internal consistency was tested using Cronbach's α. Structural validity was tested using confirmatory factor analysis (CFA) and exploratory factor analysis (EFA). Convergent validity was tested using Pearson's correlation coefficients, which were calculated between each score of the PFI scale and burnout (the Japanese Burnout Scale: JBS), depressive symptoms (the Patient Health Questionnaire-9), and QOL (the General Health Questionnaire-12). RESULTS The Cronbach's alpha was .91 in professional fulfillment, .80 in burnout: work exhaustion, .90 in burnout: interpersonal disengagement, and .89 in burnout: total score. Confirmatory factor analysis demonstrated a modest fit, and EFA yielded a three-factor structure the same as the original PFI. The all three subscales and total score of burnout were significantly correlated with the scores of all the scales (p < .001; e.g., burnout: work exhaustion correlated emotional exhaustion in JBS, r = .71). CONCLUSIONS The Japanese version of the PFI demonstrated acceptable high internal consistency, structural validity, and convergent validity of the scale with a three-factor structure the same as in the original PFI. The Japanese version of PFI proved to be reliable and valid for use in healthcare professionals.

Abstract
Coronavirus disease 2019 (COVID-19) infection prevention measures have led to a variety of mental health issues. Although several self-care methods have been recommended for those quarantined, evidence regarding how best to support quarantined people experiencing a mental health crisis is limited. In February 2020, the Diamond Princess cruise ship was quarantined in Yokohama port, Japan following a passenger testing positive for COVID-19. We were sent to address the mental health issues as the Disaster Psychiatric Assistance Team (DPAT). In the present study, we examined the acute mental health needs of the passengers and crew collected by the DPAT using the standard Emergency Medical Team daily reporting system. We assessed 206 cases (99 men and 107 women) with generic health issues and 127 cases (39 men and 88 women) with mental health issues. Mental health issues including disaster stress-related symptoms were as frequent as physical health events associated with COVID-19. The most significant mental health issue was anxiety, as an acute psychological reaction to the quarantine situation. Women and crews most frequently needed mental health support. Mental health improved in most clients after brief counseling. Although several passengers experienced suicidal ideation, there were no cases of actual suicide attempts during the quarantine period. This case has been regarded as a well-known public health event at the beginning of the COVID-19 era. In addition to physical health support, disaster mental health support was essential to save lives. Our findings may facilitate responses to future quarantines, accidents, and mental health crises.

Abstract
It is crucial to provide mental health care following a disaster because the victims tend to experience symptoms such as anxiety and insomnia during the acute phase. However, little research on mental health during the acute phase has been conducted, and reported only in terms of the temporal transition of the number of consultations and symptoms. Thus, the aim of the study was to examine how mental health care needs are accounted for in the overall picture of disaster relief and how they change over time. Using data from the Japanese version of Surveillance in Post-Extreme Emergencies and Disasters (J-SPEED), we assessed the mental health of injured and ill patients to whom Emergency Medical Teams (EMTs) were providing care during the acute period of a disaster. Approximately 10% of all medical consultations were for mental health issues, 83% of which took place within the first 2 weeks after the disaster. The findings showed that, from the start of the response period to the 19th response day, the daily proportion of mental health problems declined substantially, and then gradually increased. Such a V-shaped pattern might be helpful for identifying phase changes and supporting the development of EMT exit strategies.

Abstract
This study aimed to compare the longitudinal change in depressive symptoms among healthcare professionals in Japan who are willing to receive novel coronavirus disease (COVID-19) vaccination and those who are unwilling to receive COVID-19 vaccination. The baseline survey was conducted in October 2020 (Survey time 1: T1); respondents in T1 were invited to participate in May 2021 (Survey time 2: T2). Depressive symptoms were assessed by the Patient Health Questionnaire-9 (PHQ-9). Group comparisons of the estimated mean of PHQ-9 score at T1 and T2 were estimated by the analysis of covariance. In T1, 597 participants (response rate: 4.4%) completed all questions. In T2, 211 participants (follow up rate: 35.3%) completed all questions. The group and time interaction effect was significant (F(1, 207)=3.9, p=0.049); depressive symptoms were worse among healthcare professionals who were unwilling to receive vaccination than among those who were willing to receive vaccination. This study showed that depressive symptoms were worse among healthcare professionals who were unwilling to receive COVID-19 vaccination than those who are willing to receive COVID-19 vaccination. This suggests that it is important to take care of healthcare professionals who are unwilling to receive vaccination to prevent mental health deterioration.

Abstract
Colorectal cancer metastasis to the retroperitoneum, especially solitary metastasis allowing curative resection, is rare. We report a case of complete resection of retroperitoneal metachronous solitary metastasis from caecal cancer without distant metastasis. An 80-year-old woman with caecal cancer underwent laparoscopic ileocaecal resection with regional lymph node dissection. According to the eighth edition of the TNM classification, the pathological diagnosis was stage IIA (T3N0M0). Six months following the surgery, computed tomography revealed a solitary mass of 2cm diameter, dorsal to the right kidney. A second procedure for the removal of the tumour was performed. The lesion was pathologically diagnosed as a metachronous solitary retroperitoneal metastasis from caecal cancer. The patient is surviving and free from recurrence 17 months following the second procedure.

Abstract
BACKGROUND Around 20% of patients with acute coronary syndrome (ACS) develop depression. Furthermore, some observational studies revealed baseline polyunsaturated fatty acids (PUFAs) may affect the prognosis of depression after ACS. This prospective cohort study examined the association between psychiatric disorder and PUFAs after ACS. METHODS Subjects were ACS patients admitted to a Tokyo teaching hospital. Psychiatric morbidity as a primary endpoint was measured using structured interview 3 months after admission. At admission, serum n-3 and n-6 PUFAs were measured by gas chromatography and patients were interviewed to evaluate medical information. Multiple logistic regression analysis was performed to calculate odds ratios (ORs) and 95% confidence intervals to examine the association between PUFAs at baseline and psychiatric disorder after ACS. RESULTS Between March 2014 and August 2016, 100 patients completed the follow-up assessment. Eleven patients (11%) showed some form of new-onset psychiatric disorder at 3 months, mainly depressive episode (major, 5; minor, 1) and PTSD (full, 1; partial, 2). Psychiatric disorder was predicted by serum linoleic acid level (OR=3.96) and Hospital Anxiety and Depression Scale total score (OR=1.34) at baseline. No significant associations were seen with other PUFAs. LIMITATIONS The results were obtained from a single hospital and based on a small number of participants. There might be some patients with new-onset psychiatric disorder among the refused patients. CONCLUSIONS Psychiatric disorder incidence in ACS patients might be lower in Japan than in Western countries. Reduced intake of linoleic acid-containing foods might prevent depression or PTSD after ACS.

Abstract
BACKGROUND Total gastrectomy for gastric cancer is associated with excessive weight loss and decreased calorie intake. Nutritional support using eicosapentaenoic acid modulates immune function and limits catabolism in patients with advanced cancer, but its impact in the perioperative period is unclear. METHODS This was a randomized phase III clinical trial of addition of eicosapentaenoic acid-rich nutrition to a standard diet in patients having total gastrectomy for gastric cancer. Patients were randomized to either a standard diet or standard diet with oral supplementation of an eicosapentaenoic acid (ProSure®), comprising 600 kcal with 2·2 g eicosapentaenoic acid, for 7 days before and 21 days after surgery. The primary endpoint was percentage bodyweight loss at 1 and 3 months after surgery. RESULTS Of 127 eligible patients, 126 were randomized; 124 patients (61 standard diet, 63 supplemented diet) were analysed for safety and 123 (60 standard diet, 63 supplemented diet) for efficacy. Across both groups, all but three patients underwent total gastrectomy with Roux-en-Y reconstruction. Background factors were well balanced between the groups. Median compliance with the supplement in the immunonutrition group was 100 per cent before and 54 per cent after surgery. The surgical morbidity rate was 13 per cent in patients who received a standard diet and 14 per cent among those with a supplemented diet. Median bodyweight loss at 1 month after gastrectomy was 8·7 per cent without dietary supplementation and 8·5 per cent with eicosapentaenoic acid enrichment (P = 0·818, adjusted P = 1·000). Similarly, there was no difference between groups in percentage bodyweight loss at 3 months (P = 0·529, adjusted P = 1·000). CONCLUSION Immunonutrition based on an eicosapentaenoic acid-enriched oral diet did not reduce bodyweight loss after total gastrectomy for gastric cancer compared with a standard diet.

Abstract
OBJECTIVES Although attention has been paid to post-traumatic stress disorder (PTSD) among health care professionals after disasters, the impact of traumatic events on their work has not been elucidated. The aim of this study was to examine whether disaster-related distress, resilience, and post-traumatic growth (PTG) affect work engagement among health care professionals who had been deployed to the areas affected by the Great East Japan Earthquake that occurred on March 11, 2011. METHODS We recruited disaster medical assistance team members who were engaged in rescue activities after the earthquake. The short version of the Resilience Scale (RS-14) and Peritraumatic Distress Inventory (PDI) were administered one month after the earthquake, and the short form of Posttraumatic Growth Inventory (SF-PTGI) and Utrecht Work Engagement Scale (UWES) were administered four years after the earthquake. Work engagement is composed of vigor, dedication, and absorption. Regression analyses were used to examine the relationship of UWES with RS-14, PDI, and SF-PTGI. RESULTS We obtained baseline data of 254 participants in April 2011, and 191 (75.2%) completed the follow-up assessment between December 2014 and March 2015. The results showed that RS-14 predicted vigor, dedication, and absorption; in addition, SF-PTGI was positively related with these three parameters (p<0.01 for all). CONCLUSIONS Resilience at baseline and PTG after rescue activities may increase work engagement among health care professionals after disasters. These findings could be useful for establishing a support system after rescue activities during a large-scale disaster and for managing work-related stress among health care professionals.

Abstract
BACKGROUND AND PURPOSE Human papillomavirus-associated oropharyngeal squamous cell carcinoma is increasing in prevalence and typically occurs in younger patients than human papillomavirus-negative squamous cell carcinoma. While imaging features of human papillomavirus-positive versus human papillomavirus-negative squamous cell carcinoma nodal metastases have been described, characteristics distinguishing human papillomavirus-positive from human papillomavirus-negative primary squamous cell carcinomas have not been well established. The purpose of this project was to evaluate the use of texture features to distinguish human papillomavirus-positive and human papillomavirus-negative primary oropharyngeal squamous cell carcinoma. MATERIALS AND METHODS Following institutional review board approval, 40 patients with primary oropharyngeal squamous cell carcinoma and known human papillomavirus status who underwent contrast-enhanced CT between December 2009 and October 2013 were included in this study. Segmentation of the primary lesion was manually performed with a semiautomated graphical-user interface. Following segmentation, an in-house-developed texture analysis program extracted 42 texture features from each segmented volume. A t test was used to evaluate differences in texture parameters between human papillomavirus-positive and human papillomavirus-negative squamous cell carcinomas. RESULTS Of the 40 included patients, 29 had human papillomavirus-positive oropharyngeal squamous cell carcinoma and 11 had human papillomavirus-negative oropharyngeal squamous cell carcinoma. Significant differences were seen in the histogram parameters median (P = .006) and entropy (P = .016) and squamous cell carcinoma entropy (P = .043). CONCLUSIONS There are statistically significant differences in some texture features between human papillomavirus-positive and human papillomavirus-negative oropharyngeal tumors. Texture analysis may be considered an adjunct to the evaluation of human papillomavirus status and characterization of squamous cell carcinoma.

Abstract
BACKGROUND Antimicrobial photodynamic therapy (aPDT) is a new treatment method for the removal of infectious pathogens using a photosensitizer and light of a specific wavelength, e.g., toluidine blue with a wavelength of about 600 nm. We explored a new photosensitizer and focused on indocyanine green (ICG), which has high absorption at a wavelength of 800-805 nm. We investigated the bactericidal effect of PDT on Porphyromonas gingivalis using a new photosensitizer, ICG-loaded nanospheres with an 805 nm wavelength low-level diode laser irradiation. METHODS We designed ICG-loaded nanospheres coated with chitosan (ICG-Nano/c) as a photosensitizer. A solution containing Porphyromonas gingivalis (10(8) CFU/mL) with or without ICG-Nano/c (or ICG) was prepared and irradiated with a diode laser or without laser irradiation as a negative control. The irradiation settings were 0.5 W with a duty ratio of 10%, for 3-100 ms in repeated pulse (RPT) or continuous wave mode. CFU were counted after 7 d of anaerobic culture. RESULTS We observed that ICG-Nano/c could adhere to the surface of P. gingivalis. When ICG-Nano/c was used for aPDT, irradiation with RPT 100 ms mode gave the lowest increase in temperature. Laser irradiation with ICG-Nano/c significantly reduced the number of P. gingivalis (i.e., approximately 2-log10 bacterial killing). The greatest bactericidal effect was found in the RPT 100 ms group. However, laser irradiation (RPT 100 ms) with ICG, as well as without photosensitizer, had no effect on the number of bacteria. CONCLUSIONS Within the limits of this study, ICG-Nano/c with low-level diode laser (0.5 W; 805 nm) irradiation showed an aPDT-like effect, which might be useful for a potential photodynamic periodontal therapy.

Abstract
Abstract
The release behaviour of theophylline encapsulated in the inner aqueous phase of a water/oil/water emulsion was investigated by two methods. A cellulose tube containing a sample of the emulsion was placed in a rotary basket and was stirred in a dissolution medium (Method A), or the w/o/w emulsion was dispersed in a dissolution medium and the system was stirred by a paddle, allowing the drug to permeate into a cellulose tube placed in the dispersing medium (Method B).
In Method A, the drug release rate from the emulsion decreased with increase in the concentration of sodium chloride co-formulated with the drug in the inner aqueous phase. The drug release rate in the dissolution test medium No. 1 or No. 2 of the JP XII was greater than that in purified water and was increased with the ionic strength of the dissolution medium. The drug was released more rapidly in Method B than in Method A, because the emulsion was destroyed more easily using the former method. As this destruction of emulsion structure occurred immediately after dilution with dissolution medium, the influence of the dissolution medium on the release profile could not be detected using Method B.
The experimental data of drug release were satisfactorily explained by the destruction model of the oil membranes of the water/oil/water emulsions.

Abstract
BACKGROUND Locally advanced gastric cancer with extensive lymph node metastasis is usually considered unresectable and so treated by chemotherapy. This trial explored the safety and efficacy of preoperative chemotherapy followed by extended surgery in the management of locally advanced gastric adenocarcinoma. METHODS Patients with gastric cancer with extensive lymph node metastasis received two or three 28-day cycles of induction chemotherapy with irinotecan (70 mg/m(2) on days 1 and 15) and cisplatin (80 mg/m(2) on day 1), and then underwent gastrectomy with curative intent with D2 plus para-aortic lymphadenectomy. Primary endpoints were 3-year overall survival and incidence of treatment-related death. RESULTS The study was terminated because of three treatment-related deaths when 55 patients had been enrolled (mortality rate above 5 per cent). Two deaths were due to myelosuppression and one to postoperative complications. Clinical response and R0 resection rates were 55 and 65 per cent respectively. The pathological response rate was 15 per cent. Median overall survival was 14.6 months and the 3-year survival rate 27 per cent. CONCLUSION This multimodal treatment of locally advanced gastric cancer provides reasonable 3-year survival compared with historical data, but at a considerable cost in terms of morbidity and mortality.

Abstract
AIMS/HYPOTHESIS Although it is known that lipid metabolism plays a role in insulin resistance in type 2 diabetes and in obesity, the mechanism is still largely unknown. Apolipoprotein E (ApoE) regulates plasma lipid levels and also plays a role in the uptake of lipids into various tissues. To investigate whether the suppression of whole-particle lipoprotein uptake into tissues affects insulin responsiveness and the diabetic condition, we examined the effect of an ApoE (also known as Apoe) gene deletion in MKR mice, a mouse model of type 2 diabetes. METHODS ApoE ( -/- ), MKR, ApoE ( -/- )/MKR and control mice were placed on a high-fat, high-cholesterol diet for 16 weeks. Glucose tolerance, serum insulin, blood glucose, insulin tolerance, tissue triacylglycerol content and atherosclerotic lesions were assessed. RESULTS ApoE ( -/- )/MKR and ApoE ( -/- ) mice showed significantly improved blood glucose, glucose tolerance and insulin sensitivity. Reduced triacylglycerol content in liver and reduced fat accumulation in liver and adipose tissue were found in ApoE ( -/- )/MKR and ApoE ( -/- ) mice compared with control and MKR mice. ApoE ( -/- ) and ApoE ( -/- )/MKR mice demonstrated similarly large atherosclerotic lesions, whereas MKR and control mice had small atherosclerotic lesions. CONCLUSIONS/INTERPRETATION We demonstrated that ApoE deficiency abrogates insulin resistance in a mouse model of type 2 diabetes, suggesting that lipid accumulation in tissue is a major cause of insulin resistance in this mouse model.

Abstract
BACKGROUND In chronic aortic regurgitation, eccentric hypertrophy, with combined concentric hypertrophy of the left ventricle, is an important adaptive response to volume overload, which in itself is a compensatory mechanism for permitting the ventricle to normalize its afterload and to maintain normal ejection performance (physiologic hypertrophy). However, progressive dilatation of the left ventricle leads to depressed left ventricular (LV) contractility and myocardial structural changes, including cellular hypertrophy and interstitial fibrosis (pathological hypertrophy). HYPOTHESIS The study was undertaken to determine the relationship between left ventricular myocardial structure and contractile function in 14 patients with chronic aortic regurgitation by cardiac catheterization and endomyocardial biopsies. METHODS Myocardial cell diameter and percent interstitial fibrosis were obtained from biopsy samples. Contractile function was evaluated from the ratio of end-systolic wall stress to end-systolic volume index (ESS/ESVI) and the ejection fraction-end-systolic stress (EF-ESS) relationship, which was obtained from 30 normal control subjects. RESULTS Myocardial cell diameter correlated significantly with the ESVI (r = 0.72, p < 0.005), ejection fraction (r = -0.58, p < 0.05), and ESS/ESVI (r = -0.58, p < 0.05). The percent interstitial fibrosis also correlated inversely with ESS/ESVI (r = -0.71, p < 0.005). Compared with very few patients with an ESVI < 70 ml/m2, the majority of patients with ESVI > or = 70 ml/m2 had a cell diameter of > or = 30 microns and a percent interstitial fibrosis of > or = 10%. The nine patients who had depressed contractile function, as assessed from the EF-ESS relationship, had a higher percent interstitial fibrosis (p < 0.05) than five patients showing a normal EF-ESS relationship, despite the fact that there was no significant difference in myocardial cell diameter between them. Thus, advanced cellular hypertrophy and excessive interstitial fibrosis were significantly and independently associated with myocardial contractile dysfunction and appeared to be responsible for ventricular remodeling. CONCLUSION Our findings suggest that in many patients with aortic regurgitation, eccentric hypertrophy changes its nature from physiologic to nonphysiologic during the earlier stages in the course of the disease rather than during the stage described previously.

Abstract
The objectives of this study were to observe the penetrative and mucoadhesive behavior of polymer-coated liposomes into the intestinal mucosa of rats. Chitosan (CS) and negatively charged liposomes were chosen as model polymer-coated liposomes. In order to observe their behavior, chitosan was labeled with Fluorescence Isothiocyanate (FITC) via chemical reaction at the isothiocyanate group of FITC and the primary amino group of chitosan; the liposomes (Lips) were marked by incorporation of DiI into the liposomal formulation. FITC-labeled chitosan (FITC-CS), Non-Lips, and FITC-labeled CS-coated Liposomes (FITC-CS-Lips) were intragastrically administered into male Wistar rats, and the behavior of the molecules was subsequently visualized by CLSM (Confocal Laser Scanning Microscopy). The results demonstrated that the chitosan molecules themselves, as well as the liposomes, could penetrate across the intestinal mucosa. Moreover, the CLSM images demonstrated a lack of separation of the chitosan molecules from the surface of the liposomes after the administration of chitosan-coated liposomes.
