RESUMO
OBJECTIVE: Refeeding hypophosphatemia (RH) is a potentially fatal complication in patients with anorexia nervosa (AN), and its dietary preventive strategy is not well established. We aimed to examine the association between carbohydrate content in the diet and the occurrence of RH in inpatients with AN via retrospective medical chart review. METHOD: We performed a chart review to collect data of patients with AN hospitalized at the Department of Psychosomatic Medicine of the University of Tokyo Hospital between April 1, 2012, and February 29, 2020. Receiver operating characteristic (ROC) analysis was performed to determine the cutoff point of the percentage of carbohydrate content in the diet for the occurrence of RH. Multivariate logistic regression analysis was performed with occurrence of RH as the dependent variable and the carbohydrate content of more than the identified cutoff point as the independent variable adjusting for the risk factors for RH. RESULTS: The percentage of carbohydrate content that is higher than the cutoff point obtained from the ROC analysis (58.4%) was significantly associated with the occurrence of RH, even after adjusting for variables associated with RH in univariate logistic regression analysis (age and body mass index) as well as the average daily calorie intake (odds ratio, 5.37; 95% confidence interval, 1.60-18.1; p = .0066). DISCUSSION: We identified that diets with higher carbohydrate contents were associated with RH in inpatients with AN, even after adjusting for known risk factors. Our findings may promote the development of dietary preventive strategies against RH in inpatients with AN.

OBJECTIVE: Refeeding hypophosphatemia (RH) is a life-threatening complication in underweight patients with eating disorders (EDs). Although a lower body mass index (BMI) has been reported as a risk factor for RH, the exact BMI cut-off point is not known. Herein, we aimed to identify the optimal BMI cut-off point for RH in adults with EDs. METHOD: The medical charts of Japanese inpatients with EDs at our hospital between April 1, 2012 and March 31, 2017 were retrospectively reviewed. The optimal BMI cut-off point for RH was determined via receiver operating characteristic analysis. Logistic regression analysis was subsequently performed to assess the association between RH and the BMI cut-off point after adjusting for the propensity score, which was based on known risk factors for RH. RESULTS: The optimal BMI cut-off point was identified as 12.6 kg/m2 . A BMI lower than the cut-off point significantly correlated with the occurrence of RH after adjusting for the propensity score. DISCUSSION: The optimal BMI cut-off point for the occurrence of RH was 12.6 kg/m2 in adults with EDs. The findings of the present study may facilitate clinical decision making and early identification of patients who require prophylactic treatment for RH.

Previous studies have successfully predicted overweight status by applying deep learning to 12-lead electrocardiogram (ECG); however, models for predicting underweight status remain unexplored. Here, we assessed the feasibility of deep learning in predicting extremely low body weight using 12-lead ECGs, thereby investigating the prediction rationale for highlighting the parts of ECGs that are associated with extremely low body weight. Using records of inpatients predominantly with anorexia nervosa, we trained a convolutional neural network (CNN) that inputs a 12-lead ECG and outputs a binary prediction of whether body mass index is ≤ 12.6 kg/m2. This threshold was identified in a previous study as the optimal cutoff point for predicting the onset of refeeding syndrome. The CNN model achieved an area under the receiver operating characteristic curve of 0.807 (95% confidence interval, 0.745-0.869) on the test dataset. The gradient-weighted class activation map showed that the model focused on QRS waves. A negative correlation with the prediction scores was observed for QRS voltage. These results suggest that deep learning is feasible for predicting extremely low body weight using 12-lead ECGs, and several ECG features, such as lower QRS voltage, may be associated with extremely low body weight in patients with anorexia nervosa.

CONTEXT: The Quality of Life at the End of Life-Cancer Scale (QUAL-EC) is a self-reported instrument to assesses the quality of life of patients with cancer near the end of life. OBJECTIVE: To test the reliability and validity of the QUAL-EC-J, a Japanese translated version of the QUAL-EC. METHODS: A total of 179 Japanese patients with advanced cancer completed the QUAL-EC-J, Patient Health Questionnaire-9, Generalized Anxiety Disorder-7, Rosenberg Self-Esteem Scale, Multidimensional Scale of Perceived Social Support, Functional Assessment of Cancer Therapy-General Scale, and Functional Assessment of Chronic Illness Therapy-Spiritual questionnaires. We performed confirmatory factor analysis of the four structures of the QUAL-EC and exploratory factor analysis of the QUAL-EC-J. Internal consistency was assessed using Cronbach's α coefficient and validity was examined by calculating correlations with relevant scales. RESULTS: Confirmatory factor analysis showed an inadequate fit to the original QUAL-EC structure. Exploratory factor analysis revealed a three-factor structure of the QUAL-EC-J, with Cronbach's α values of 0.68-0.88. All subscales were negatively correlated with depression and anxiety. Each subscale was correlated with related measures: "symptom control" with "physical well-being"; "acceptance of disease and life" with "social and family well-being" and "meaning/peace"; and "preparation for end of life" with "emotional well-being" and "meaning/peace." CONCLUSIONS: The QUAL-EC-J has a three-factor structure with acceptable reliability and sufficient validity. Differences in the factor structure between the QUAL-EC-J and the QUAL-EC may be due to cultural factors. Study findings suggest that utilization of the QUAL-EC-J could help to improve research and clinical care in advanced cancer in Japan.

BACKGROUND: The superiority of Enhanced Cognitive Behavior Therapy (CBT-E) with regard to weight gain and improvement of psychopathology of eating disorders for patients with anorexia nervosa (AN) over other psychotherapies and treatment as usual (TAU) has not been demonstrated in randomized controlled trials (RCTs). However, a previous RCT showed that patients with AN whose baseline body mass index (BMI) was less than 17.5 kg/m2 gained more weight when treated with CBT-E than with other psychotherapies. The aim of the study is to compare the efficacy of CBT-E and TAU for patients with AN. It was hypothesized that CBT-E would be superior to TAU, at least in terms of weight gain, as most patients with AN are likely to have a BMI lower than 17.5 kg/m2. METHODS/DESIGN: A randomized parallel-group multicenter trial will be conducted in three teaching hospitals in Japan between January 2023 and March 2026. Patients with DSM-5 AN, aged 16 years and older, with a BMI equal to or above 14.0 and below 18.5 will be eligible to participate. 56 patients will be randomly and evenly assigned to two intervention groups (CBT-E and TAU). Those assigned to CBT-E will be offered 25-40 sessions in accordance with their initial BMI. Patients assigned to TAU will have at least one session every 2 weeks, with the number of sessions and treatment period not fixed in advance. The primary outcome is BMI at 40 weeks after treatment initiation. The secondary outcomes are the results from the Japanese version of the Eating Disorder Examination Questionnaire and Clinical Impairment Assessment questionnaire to measure eating disorder psychopathology and psychological impairment. The follow-up assessment will be performed 6 months after the 40-week assessment. DISCUSSION: This multi-center randomized controlled study will probably evaluate the efficacy of CBT-E compared with TAU for patients with more severe AN than in previous studies since Japanese patients are likely to have a lower BMI than those in Western countries. While it may be difficult to generalize the results of a study conducted in Japan, it would be valuable to clarify the efficacy of CBT-E as a treatment package.

RESUMO
INTRODUCTION: Managing Cancer and Living Meaningfully (CALM) is a novel, brief and manualised psychotherapeutic intervention intended to treat and prevent depression and end-of-life distress in patients with advanced cancer. This phase 2 trial aims to assess the feasibility and preliminary efficacy of CALM in Japanese patients with cancer. METHODS AND ANALYSIS: This study is a single-arm clinical trial. All patients involved in the study are ≥18 years of age, have been diagnosed with advanced or metastatic solid-tumour cancer, and their expected survival is at least 6 months. CALM comprises three to six individual therapy sessions, each lasting approximately 45-60 min, provided over 3- 6 months. The participants will be asked to complete questionnaires at baseline (t0), 3 months (t1) and 6 months (t2). The primary outcomes are rates of completion of the intervention and of the outcome measures and improvement of depressive symptoms measured using the Patient Health Questionnaire-9 between t0 and t2. The criteria for the successful rate of completion is that at least 70% participants who participate in at least three sessions will complete measures at t2. The secondary outcomes are the improvement in scores on: (1) the Quality of Life at the End of Life-Cancer Scale, (2) the Experiences in Close Relationships scale, (3) the Death and Dying Distress Scale and (4) the Clinical Evaluation Questionnaire. ETHICS AND DISSEMINATION: This study was approved by the Research Ethics Committee of The University of Tokyo, Cancer Institute Hospital of Japanese Foundation for Cancer Research and Yamaguchi University. We will conduct the study in accordance with the Declaration of Helsinki and the Ethical Guidelines for Medical and Health Research Involving Human Subjects. The results of this study will be submitted for peer-reviewed publication and presentation at local, national and international scientific meetings and conferences.

BACKGROUND: Superior mesenteric artery (SMA) syndrome is a well-known but relatively rare complication of anorexia nervosa. Although several reports have proposed surgery for SMA syndrome associated with anorexia nervosa, these have shown poor outcomes or did not reveal the long-term weight course. Thus, the long-term effectiveness of surgery for SMA syndrome in such cases remains unclear. This case report describes a patient with anorexia nervosa who underwent surgery for SMA syndrome. CASE PRESENTATION: An 18-year-old woman presented with anorexia nervosa when she was 16 years old. She also presented with SMA syndrome, which seemed to be caused by weight loss due to the eating disorder. Nutrition therapy initially improved her body weight, but she ceased treatment. She reported that symptoms related to SMA syndrome had led to her weight loss and desired to undergo surgery. Laparoscopic duodenojejunostomy was performed, but her body weight did not improve after the surgery. The patient eventually received conservative nutritional treatment along with psychological approaches, which led to an improvement in her body weight. CONCLUSIONS: The case implies that surgery for SMA syndrome in patients with anorexia nervosa is ineffective for long-term weight recovery and that conservative treatment can sufficiently improve body weight; this is consistent with the lack of evidence on the topic and reports on potential complications of surgery. Due to difficulties in assessing psychological status, consultation with specialists on eating disorders is necessary for treating patients with severely low body weight.
RESUMO
BACKGROUND: There is growing evidence of the treatment efficacy of cognitive behavioral therapy (CBT) for irritable bowel syndrome (IBS). CBT is recommended by several practice guidelines for patients with IBS if lifestyle advice or pharmacotherapy has been ineffective. Manual-based CBT using interoceptive exposure (IE), which focuses on the anxiety response to abdominal symptoms, has been reported to be more effective than other types of CBT. One flaw of CBT use in general practice is that it is time and effort consuming for therapists. Therefore, we developed a set of complementary video materials that include psycho-education and homework instructions for CBT patients, reducing time spent in face-to-face sessions while maintaining treatment effects. The purpose of this study is to examine the effects of CBT-IE with complementary video materials (CBT-IE-w/vid) in a multicenter randomized controlled trial (RCT). METHODS: This study will be a multicenter, parallel-design RCT. Participants diagnosed with IBS according to the Rome IV diagnostic criteria will be randomized to either the treatment as usual (TAU) group or the CBT-IE-w/vid + TAU group. CBT-IE-w/vid consists of 10 sessions (approximately 30 min face-to-face therapy + viewing a video prior to each session). Patients in the CBT-IE-w/vid group will be instructed to pre- view 3- to 13-min videos at home prior to each face-to-face therapy visit at a hospital. The primary outcome is the severity of IBS symptoms. All participants will be assessed at baseline, mid-treatment, post-treatment, and follow-up (3 months after post assessment). The sample will include 60 participants in each group. DISCUSSION: To our knowledge, this study will be the first RCT of manual-based CBT for IBS in Japan. By using psycho-educational video materials, the time and cost of therapy will be reduced. Manual based CBTs for IBS have not been widely adopted in Japan to date. If our CBT-IE-w/vid program is confirmed to be more effective than TAU, it will facilitate dissemination of cost-effective manual-based CBT in clinical settings. TRIAL REGISTRATION: The trial was registered to the University Hospital Medical Information Network Clinical Trial Registry: UMIN, No. UMIN000030620 (Date of registration: December 28, 2017).
