Introduction: We report a case of sudden loss of consciousness due to hypoglycemia in the terminal stage of cancer. Case: A 73-year-old man underwent craniotomy in 2016 and was diagnosed with solitary fibrous tumor. In 2022, his brain tumor recurred and he was admitted to our hospice. On the morning of the 120th day after transfer, the patient suddenly developed impaired consciousness. Blood tests showed hypoglycemia (33 mg/dL), and intravenous glucose injection improved his loss of consciousness, leading to a diagnosis of impaired consciousness due to hypoglycemia. After various examinations, hypoglycemia due to extrapancreatic tumor (non-islet cell tumor hypoglycemia: NICTH) was strongly suspected. Discussion: NICTH is considered to be caused by excessive secretion of an insulin-like substance (high molecular weight insulin-like growth factor (IGF-)II) from the tumor. In patients who are exposed to hypoglycemia for a long period of time, central nervous system symptoms such as impaired consciousness may suddenly develop without sympathetic symptoms. NICTH should be considered as a differential diagnosis in patients with delirium, impaired consciousness, or convulsive seizures and a large tumor, although it is not easy to prove the excessive secretion of high-molecular-weight IGF-II, especially in the terminal stage of cancer.

Objectives: We compared cancer patients who were discharged home from inpatients hospices (Home), and who died at hospices (PCU) as a comparison group regarding patients’ quality of life, to clarify the patients’ experience after discharge home. Methods: We send self-reported questionnaires to bereaved families of cancer patients who were discharged home from 12 Japanese nation-wide hospices and died without readmission to the hospicies during Janually 2010 and August 2014. We used bereaved families’ data of patients who died at the same hospices during the same period of J-HOPE3 study. Results: We sent 495 questionnaires (returned 47.3%) and analyzed data of 188 as Home. The data of 759 bereaved families of J-HOPE3 study were also analyzed as PCU. In Good Death Inventory, Home was associated with higher score on some items (staying at favorite place, having pleasure, staying with families and friends, being valued as a person), and PCU was associated with higher score on being free from pain or other physical distress. Conclusions: Patients who were discharged home from inpatient hospices had good environmental QOL, but hospices may be better in palliation of symptoms.

Thoracic endovascular aortic repair (TEVAR) is valuable in the treatment of type B aortic dissection. An isolated left vertebral artery (ILVA) is a common anomaly of the aortic arch. The ILVA is covered during TEVAR in specific cases; however, whether the ILVA should be reconstructed in all cases remains controversial. We report a case of TEVAR performed for chronic aortic dissection in a patient with an ILVA. A 57-year-old woman with an ILVA had a type B acute aortic dissection one year prior to presentation and underwent TEVAR owing to dilation of an ulcer-like projection. We performed ILVA-left common carotid artery (LCCA) anastomosis and LCCA-left axillary artery bypass prior to TEVAR using our usual procedure. The postoperative course was favorable without any major complication. ILVA reconstruction may reduce the incidence of postoperative stroke and spinal cord injury. Usually, an ILVA is easily accessible through the supraclavicular approach, and the anatomical position of the vessel facilitates ILVA-LCCA anastomosis. ILVA reconstruction requires additional features and further consideration.

This paper describes the concepts of assessment theory which are necessary to implement the most desirable assessments, with a particular focus on validity and utility. Validity, classically defined as a trinity of content, criterion-related, and construct, is now encompassed by construct validity. By distinguishing between validity and validation, the process of reinforcing validity through argument-based validation is proposed. Furthermore, we refer to the concept of utility, which takes into account practicality (acceptability and cost) and educational impact, in order to make the assessment practice sustainable. Finally, we will address how learner assessment relates to program evaluation.

Methods: Thirty patients with LSS scheduled for spine surgery participated in this study. Lower limb pain was assessed using the Visual Analog Scale (VAS), and the patients were divided into two groups based on the mean scores (patients with scores above and below the mean were classified as the high-VAS and low-VAS groups, respectively). The kinematics of the spine, pelvis, and hip joints during gait were then measured using a 3D motion analysis system. Student paired t -tests were used to compare the angles of the spine, pelvis, and hip during gait between the two groups. Results: Compared to those in the low-VAS group, the spine was significantly extended and bent toward the more painful lower limb side, and the pelvis was significantly anteriorly tilted among individuals in the high-VAS group. Conclusions Patients with LSS experiencing severe pain in their lower limb tend to keep the spine in a more extended position, bend laterally toward the painful side, and have an anteriorly tilted pelvic posture. The dynamic spinal and pelvic alignment was closely related to the intensity of the lower limb pain.

Methods: Thirty patients with ASD aged ≥50 years who were admitted to our hospital between July 2016 and September 2019 were included in this study. X-ray parameters (i.e., sagittal vertical axis, pelvic tilt, and pelvic incidence minus lumbar lordosis) were evaluated from the full-length standing radiographs of the subjects. Trunk and hip extensor strength was evaluated using a hand-held dynamometer. Dynamic postural changes (i.e., sagittal trunk shift during standing, sagittal trunk shift during gait, and delta sagittal trunk shift) were assessed using a three-dimensional motion analysis system. The relationships between dynamic postural change and various X-ray parameters, as well as trunk and hip extensor strength, were examined using multivariable analysis. Results: Multivariable analysis showed that hip extensor strength is the factor most strongly associated with dynamic postural change among the X-ray parameters and physical functions assessed in this study (β=−0.41, R2=0.12). Conclusions We demonstrated the association between dynamic postural change and hip extensor strength in patients with ASD. Our results may be useful to healthcare providers treating patients with ASD. Interventions for dynamic postural change in patients with ASD should focus on hip extensor strength.

Objective: To validate and recalibrate Charlson and Elixhauser comorbidity indices (CCI and ECI, respectively) in a Japanese hospital-based administrative database.Methods: In this retrospective, cohort study, derivation and validation cohorts were developed to include all hospitalizations for patients aged ≥ 18 years at admission and discharged in 2015 or 2016, respectively, from an administrative database based on 287 hospitals. Seventeen CCI and 30 ECI conditions were identified using the International Classification of Diseases (ICD) -10 codes at admission or during the stay. Predictability for hospital death was evaluated using C statistics from multivariable logistic regression models including age, sex, and individual CCI/ECI conditions or the CCI/ECI score in the derivation cohort. After stepwise selection, weighted risk scores were re-assigned to each condition based on the odds ratios (CCI) or beta-coefficient (ECI), and these modified models were evaluated in the validation cohort.Results: The original CCI/ECI had good predictive abilities for hospital death: C statistics (95% confidence interval) for individual comorbidities and score models were 0.764 (0.762-0.765) and 0.731 (0.729-0.733) for CCI, and 0.783 (0.781-0.784) and 0.750 (0.748-0.752) for ECI, respectively. Modified CCI and ECI had 13 and 27 conditions, respectively, but maintained comparable predictive abilities: C statistics for modified individual comorbidities and score models were 0.761 (0.759-0.763) and 0.759 (0.757-0.760) for CCI, and 0.784 (0.782-0.785) and 0.783 (0.781-0.785) for ECI, respectively.Conclusions: The original and modified CCI/ECI models, with reduced numbers of conditions, had sufficient and comparable predictive abilities for hospital death and can be used in future studies using this administrative database.

Objective: The Charlson and Elixhauser comorbidity indices (CCI and ECI, respectively) are widely used to study comorbid conditions but these indices have not been validated in Japanese datasets. In this study, our objective was to validate and recalibrate CCI and ECI in a Japanese insurance claims database.Methods: All hospitalizations for patients aged≥18 years discharged between January 2011 and December 2016 were randomly allocated to derivation and validation cohorts. Predictability for hospital death and re-admission was evaluated using C statistics from multivariable logistic regression models including age, sex, and individual CCI/ECI conditions at admission month or the derived score in the derivation cohort. After stepwise variable selection, weighted risk scores for each condition were re-assigned using odds ratios (CCI) or beta coefficients (ECI). The modified models were evaluated in the validation cohort.Results: The original CCI/ECI had good discriminatory power for hospital death: C statistics (95％ confidence interval) for individual comorbidities and score models were 0.845 (0.835-0.855) and 0.823 (0.813-0.834) for CCI, and 0.839 (0.828-0.850) and 0.801 (0.790-0.812) for ECI, respectively. Modified CCI and ECI had reduced numbers of comorbidities (17 to 10 and 30 to 21, respectively) but maintained comparable discriminatory abilities: C statistics for modified individual comorbidities and score models were 0.843 (0.833-0.854) and 0.838 (0.827-0.848) for CCI, and 0.840 (0.828-0.852) and 0.839 (0.827-0.851) for ECI, respectively.Conclusions: The original and modified models showed comparable discriminatory abilities and both can be used in future studies using insurance claims databases.

Introduction: We experienced a case of pneumatosis cystoides intestinalis with intra-abdominal free air following steroid therapy for an end-stage brain tumor. Case: The patient was a 67-year-old man. He had received surgery and chemotherapy for the brain tumor, but the disease progressed and his consciousness deteriorated. Eventually, he developed aspiration pneumonia and was hospitalized. His consciousness level remained poor even after the pneumonia improved. His survival prognosis was considered to be approximately 1 month, and he was transferred to a palliative care ward. After the transfer, administration of betamethasone 8 mg/day was started for the purpose of improving his level of consciousness. Temporary improvement was observed, and administration of this drug was continued with dose adjustments, as appropriate. Six weeks after the start of betamethasone administration, when his consciousness level again deteriorated, aspiration began to recur. Chest X-rays, obtained to assess pneumonia, showed intra-abdominal free air. Pneumatosis cystoides intestinalis was confirmed by computed tomography. He had few abdominal symptoms, and was managed conservatively. He died of respiratory failure. Conclusion: Pneumatosis cystoides intestinalis is mostly secondary, and steroid therapy is considered to be one of the causes. But follow-up observation is often conservative, and judgment of discontinuation of steroid needs to be made in consideration of its effect and prognosis is there.

Objectives: A survey was conducted to investigate the usability and safety of fentanyl sublingual tablets (FST) and to examine problems associated with their proper use.

Methods: Subjects were 18 cancer inpatients who received FST for breakthrough pain in their pharmacological cancer pain management. Changes in the pain score and the occurrence of adverse effects (nausea, vomiting and somnolence) were compared before and after FST administration.

Results: The pain score before FST administration was 6.4±2.4, and this was significantly improved to 3.4±2.8 at 30 min after administration (p<0.01). Somnolence occurred significantly more often 30 min and 2 h after FST administration than immediately before administration (p<0.05). There were no differences in the occurrence of nausea and vomiting before or after FST administration. Nine patients receiving FST therapy developed xerostomia, but there were no significant changes in the pain score or occurrence of adverse effects while they had xerostomia.

Conclusion: It is essential to observe the oral condition to judge whether FST therapy is indicated, and FST should be administered after providing sufficient oral care. The results indicate the possibility of increased occurrence of somnolence as an adverse effect.
