Objective:
Hospital treatment volume affects survival in patients with endometrial cancer;notably, initial treatment at high-volume centers improves survival outcomes. Our study assessed the effect of hospital treatment volume on cost-effectiveness and survival outcomes in patients with endometrial cancer in Japan.
Methods:
A decision-analytic model was evaluated using the following variables and their impact on cost-effectiveness: 1) hospital treatment volume (low-, intermediate-, and highvolume centers) and 2) postoperative recurrent risk factors based on pathological findings (high- and intermediate-risk or low-risk). Data were obtained from the Japan Society of Obstetrics and Gynecology database, systematic literature searches, and the Japanese Diagnosis Procedure Combination database. Quality-adjusted life years (QALY) was used as a measure of effectiveness. The model was built from a public healthcare perspective and the impact of uncertainty was assessed using sensitivity analyses.
Results:
A base-case analysis showed that the incremental cost-effectiveness ratio at high-volume centers was below a willingness-to-pay (WTP) threshold of ¥5,000,000with a maximum of ¥3,777,830/4.28 QALY for the high- and intermediate-risk group, and ¥2,316,695/4.57 QALY for the low-risk group. Treatment at the high-volume centers showed better efficiency and cost-effectiveness in both strategies compared to intermediate- or lowvolume centers. Sensitivity analyses showed that the model outcome was robust to changes in input values. With the WTP threshold, treatment at high-volume centers remained cost-effective in at least 73.6% and 78.2% of iterations for high- and intermediate-risk, and lowrisk groups, respectively.
Conclusion
Treatment at high-volume centers is the most cost-effective strategy for guiding treatment centralization in patients with endometrial cancer.

Objectives:
Locomotive syndrome stage 3 (LS3), which has been established recently, may imply a greater need for care than LS stage 0 (LS0), LS stage 1 (LS1), and LS stage 2 (LS2). The relationship between LS3 and long-term care in Japan is unclear. Therefore, this study aimed to examine this relationship.
Methods:
A total of 531 patients (314 women and 217 men; mean age, 75 years) who were not classified as requiring long-term care and underwent musculoskeletal examinations in 2012 were grouped according to their LS stage. Group L comprised patients with LS3 and Group N comprised those with LS0, LS1, and LS2. We compared these groups according to their epidemiology results and long-term care requirements from 2013 to 2018.
Results:
Fifty-nine patients (11.1%) were diagnosed with LS3. Group L comprised more patients (50.8%) who required long-term care than Group N (17.8%) (P < 0.001). Group L also comprised more patients with vertebral fractures and knee osteoarthritis than Group N (33.9% vs 19.5% [P = 0.011] and 78% vs 56.4% [P < 0.001], respectively). A Cox proportional hazards model and Kaplan–Meier analysis revealed a significant difference in the need for nursing care between Groups L and N (log-rank test, P < 0.001; hazard ratio, 2.236; 95% confidence interval, 1.451–3.447).
Conclusions
Between 2012 and 2018, 50% of patients with LS3 required nursing care. Therefore, LS3 is a highrisk condition that necessitates interventions. Approaches to vertebral fractures and osteoarthritis of the knee could be key.

Methods:
This prospective cohort study analyzed patients with osteoporotic vertebral fractures admitted to the hospital between March 2018 and October 2019. Logistic regression analysis was performed to explore the predictors of vertebral collapse at >4 weeks after admission. Model 1 used basic medical information and physical functions at admission; model 2 used basic medical information and physical function and activity at >4 weeks after admission.
Results:
In the model 1 results of logistic regression analysis, cardiovascular disease (odds ratio [OR], 12.27; 95% confidence interval [CI], 1.28–117.91) was extracted as a factor affecting vertebral collapse at ≥4 weeks after admission. In the model 2 results of logistic regression analysis, cardiovascular disease (OR, 34.57; 95% CI, 2.53–471.74), movement control during one leg standing at 4 weeks (OR, 7.25; 95% CI, 1.36–38.71), and Pain Catastrophizing Scale score at 4 weeks (OR, 1.11; 95% CI, 1.01–1.21) were extracted as factors affecting vertebral collapse at ≥4 weeks after admission.
Conclusions
Our results indicate that physical functions and comorbidity affect collapse at ≥4 weeks after admission in patients with osteoporotic vertebral fractures.

Context: Delirium in cancer is often difficult to control and refractory when haloperidol is invalid which is considered standard therapy. We need second and subsequent-line therapy to reduce hyperactivity and not to over-sedation for refractory delirium. Objectives: To investigate the efficacy and safety of continuous subcutaneous infusion chlorpromazine on delirium refractory to first-line antipsychiatric medications in advanced cancer palliative care setting. Method: The study population consisted of patients who received continuous subcutaneous infusion chlorpromazine for delirium at two certified PCU. Primary endpoint was the proportion of patients who showed improvements in delirium severity by Delirium Rating Scale Revised 98 score of less than 13 or decrease from baseline and maintained the ability to communicate coherently by Communication Capacity Scale Item-4 score of 2 or less. Secondary outcome were the Nursing Delirium Screening Scale subscale score, and injection site reactions evaluated according to the Common Terminology Criteria for Adverse Events. These outcome measures were assessed at baseline, 48 hours and 7 days after the start of the study. Result: Among eighty-four patients, sixty were positive responders (71.4%, 95% CI [61–80]). The mean CCS Item-4 scores significantly decreased from the baseline value of 1.48 (range 0–3) to 1.03 (range 0–3) at post-treatment (p<0.001). Grade 2 or higher injection site reactions were observed in 1 patient (1.2%, 95% CI [0–7]). Conclusion: Our study suggested that continuous subcutaneous infusion chlorpromazine could improve refractory delirium symptoms and patients’ communication capabilities. Although most of the skin disorders observed in association with chlorpromazine were mild, their incidence rates were relatively high, suggesting the need for careful monitoring.

Purpose: Blepharospasm is a condition characterized by abnormal contractions or twitching of the eyelid due to excessive contractions of the orbicular muscle. The purpose of the present study was to clarify the prevalence and severity of blepharospasm in end-term cancer patients and to clarify the correlation between agonal facies and angor animi or blepharospasm. Method: Diagnoses were made using the Wakakura method and the nictitating stress test, and the severity of the condition was evaluated on the basis of a palpebral dystonia grade classification system. In this positive observational study, all patients were hospitalized in our institution between October and December 2010. Result: Of the 51 evaluations, 19 (37.3%) were diagnosed with blepharospasm, and the severity of nine was ≥3 according to a five-point grading scale. Many cases were treated using antipsychotics or benzodiazepine, and an improvement was observed in all the seven cases that had medication adjustments. Diagnostically, there was no correlation between glabellar lines and pain. Agonal facies in end-term cancer patients included elements of blepharospasm in addition to angor animi. Conolusion: Blepharospasm frequently occurred in patients admitted in the palliative care unit, and it decreased their quality of life. It is important to evaluate this condition and to consider medication adjustments.

BACKGROUND: Free fat graft has been used for the treatment of congenital hand differences. However, there have been a few reports about the outcome of that treatment. In this study, the outcome of free fat grafts for congenital hand and foot differences was investigated. METHODS: Fourteen bones with longitudinal epiphyseal bracket, 3 wrists with Madelung deformity, and 5 cases of osseous syndactyly were treated with free fat graft with osteotomy, physiolysis, or separation of osseous syndactyly. Of the fourteen bones with longitudinal epiphyseal bracket, 9 were treated with open wedge osteotomy with free fat graft and 5 with physiolysis and free fat graft. The Madelung deformity was treated with physiolysis with free fat graft. For osseous syndactyly, syndactyly release with free fat graft was performed five times on four hands. RESULTS: In the fourteen cases with longitudinal epiphyseal bracket, lateral deviation improved in all except two cases after surgery. The average lateral deviation angle changed from 32.5 degrees before surgery to 15.2 degrees after surgery. The average improvement of the lateral deviation angle was 12.2 degrees in the osteotomy group and 20.6 degrees in the physiolysis group. The mean ratio of improvement of the lateral deviation angle to the lateral deviation angle before surgery was 39.4% in the osteotomy group and 51.2% in the physiolysis group. The Madelung deformity improved after surgery in two cases but there was no improvement in one case. For these conditions, the results were not good enough when surgery was done after age 13 or at age four for severely hypoplastic brachymesophalangy. Of the 5 cases of osseous syndactyly, reunion of the separated bones occurred in one case. The grafted free fat should be deep enough to cover the osteotomy site of the bones to prevent reunion of the separated bones. CONCLUSIONS: Physiolysis and free fat graft performed during the growth period can correct the deviation due to longitudinal epiphyseal bracket and Madelung deformity. Free fat graft is also useful to prevent reunion of the bones after separation of osseous syndcatyly, if the grafted fat is securely filled into the space between the separated bones.
