Objectives: Chronic kidney disease (CKD) complicated by secondary hyperparathyroidism (SHPT) is associated with an increased risk of fragility fractures. Etelcalcetide (EC) is a treatment for SHPT that reduces serum parathyroid hormone (PTH) levels. However, the effects of combined treatment with osteoporosis drugs such as teriparatide (TPTD) remain unclear. This study investigates the combined effects of EC and TPTD on bone in CKD model rats. Methods: The CKD model was established in 8-week-old male Wistar rats by feeding them a 0.75% adenine diet for 4 weeks. At 20 weeks of age, the rats were divided into 4 groups (n = 9–10 in each group): CKD group (vehicle administration), TPTD group (30 μg/kg, 3 times/week), EC group (0.6 mg/kg, daily), and Comb group (TPTD and EC combined). EC was injected for 12 weeks starting at 20 weeks of age, and TPTD was injected for 8 weeks starting at 24 weeks of age. After treatment, the followings were evaluated: bone mineral density, bone strength, biochemical tests, bone and fat histomorphometry, and micro-computed tomography. Results: In CKD model rats, the combination of EC and TPTD was more effective in increasing cortical bone thickness and bone strength and inhibiting porosity. In addition, the combined treatment decreased bone marrow adiposity and fibrosis, and it increased bone mass and improved bone microstructure in trabecular bone. Conclusions With the observed benefits such as improved bone mass, bone strength, structural properties, and bone marrow adiposity, combination therapy may be a potential way to improve bone fragility in CKD.

Objectives: Spiritual pain is not formally defined. The aim of this study was to clarify the beliefs about spiritual pain among Japanese palliative care physicians and liaison psychiatrists and to compare their beliefs. Methods: A nationwide questionnaire survey was conducted by mail August, 2019 on certified palliative care physicians and liaison psychiatrists. We asked 9 questions about spiritual pain (i.e. current status, definition, and the delivery of care) using a 5-Likert scale. Result: 387 palliative care physicians (response rate, 53%) and 374 psychiatrists (45%) responded. 72% (76% of the palliative care physicians/69% of the psychiatrists) reported that spiritual pain was distinct from depression, but 69% (66/71) reported that it was not defined adequately; and 59% (59/60) perceived the risks of using the words ambiguously. Only 43% (40/47) recommended the universal definition of spiritual pain, and opinions about how spiritual pain should be defined (i.e, higher being, meaning/value, or specific terms) differed among physicians. Perception about spiritual pain of the physicians were significantly associated with their religion, while beliefs about spiritual pain were essentially similar between palliative care physicians and psychiatrists. Conclusion: Although physicians regarded the definition of spiritual pain as being inadequate, the opinions about preferable definition differed among physicians. Discussion about the value of developing a consensus of spiritual pain is needed.
