Background and Objectives : The immunomodulatory drug thalidomide can inhibit angiogenesis and induce apoptosis in experimental models. It can also induce marked and durable response in newly diagnosed myeloma patients. Thalidomide has been used at doses ranging from 200 to 800 mg with significant toxicity. No data are available on the impact of low-dose thalidomide, cyclophosphamide and dexamethasone as initial therapy for myeloma patients. Design and Methods : To address this issue, newly diagnosed myeloma patients were treated with 50 mg/day thalidomide continuously and cyclophosphamide 150 mg/m², days 1-4 and dexamethasone 20 mg/m², days 1-5 and day 15-19, every month. Between October 2005 and October 2006, 14 patients (median age 54.5 years) were treated with low-dose thalidomide, cyclophosphamide and dexamethasone. Results : After a minimum of two cycles of treatment, 5 patients (55.5%) showed a partial remission. After four cycles of treatment, 10 patients (83.3%) showed a partial remission (n=6) and complete remission (n=4). After a median follow-up of 15.4 months, 1 year overall survival rate was 82.0%. Thalidomide was well tolerated without serious toxic effects. Conclusions : The combination of low-dose thalidomide, cyclophosphamide and dexamethasone demonstrates favorable response rate and 1 year overall survival rate in newly diagnosed myeloma. Severe toxicities were not seen with this combination.

Purpose : To observe and evaluate the effects of Simvastatin-induced osteogenesis on the wound healing of defective bone. Materials and Methods : 64 defective bones were created in the parietal bone of 32 New Zealand White rabbits. The defects were grafted with collagen matrix carriers mixed with Simvastatin solution in the experimental group of 16 rabbits and with collagen matrix carriers mixed with water in the controlled group. The rabbits were terminated at an interval of 3, 5, 7, and 9 days, 2, 4, 6, and 8 weeks after the formation of defective bone. The wound healing was evaluated by soft X-ray radiography. The tissues within defective bones were evaluated through the analysis of flow cytometry for the manifestation of Runx2 and Osteocalcin, and observed histopathologically by using H-E stain and Masson’s trichrome stain. Results : 1. In the experimental group, flow cytometry revealed more manifestation of Runx2 at 5, 7, and 9 days and Osteocalcin at 2 weeks than in the controlled groups, but there was few difference in comparison with the controlled group. 2. In the experimental group, flow cytometry revealed considerably more cells and erythrocytes at 5, 7, and 9 days in comparison with the controlled group. 3. In the experimental group, soft x-ray radiography revealed the extended formation of trabeculation at 2, 4, 6, and 8 weeks. 4. Histopathological features of the experimental group showed more fibroblasts and newly formed vessels at 5 and 7 days, and the formation of osteoid tissues at 9 days, and the newly formed trabeculations at 4 and 6 weeks. Conclusion : As the induced osteogenesis by Simvastatin, there was few contrast of the manifestation between Runx2 and Osteocalcin based on the differentiation of osteoblasts. But it was considered that the more formation of cells and erythrocytes depending on newly formed vessels in the experimental group obviously had an effect on the bone regeneration.

Purpose: For the dignity of patients nearing the end of their lives, it is essential to provide end-of-life (EoL) care in a separate, dedicated space. This study investigated the utilization of specialized rooms for dying patients within a hospice unit. Methods: This retrospective study examined patients who died in a single hospice unit between January 1, 2017, and December 31, 2021. Utilizing medical records, we analyzed the circumstances surrounding death, the employment of specialized rooms for terminally ill patients, and the characteristics of those who received EoL care in a shared room. Results: During the 1,825-day survey period, deaths occurred on 632 days, and 799 patients died. Of these patients, 496 (62.1%) received EoL care in a dedicated room. The average duration of using this dedicated space was 1.08 days. Meanwhile, 188 patients (23.5%) died in a shared room. Logistic regression analysis revealed that a longer stay in the hospice unit was associated with a lower risk of receiving EoL care in a shared room (odds ratio [OR]=0.98, 95% confidence interval [CI] 0.97~0.99; P=0.002). Furthermore, a higher number of deaths on the day a patient died was associated with a greater risk of receiving EoL care in a shared room (OR=1.66, 95% CI 1.33~2.08; P<0.001). Conclusion: To ensure that more patients receive EoL care for an adequate duration in a private setting, additional research is necessary to increase the number of dedicated rooms and incorporate them into the hospice unit at an early stage.

Background: Obstructive sleep apnea (OSA) is considered to be associated with neurocognitive dysfunction, depression, quality of life and cardiovascular diseases. OSA is likely to have a significant impact on the health of older adults. This study was to identify characteristics of older adults with high risk for OSA according to age and gender. Methods: This study was conducted on adults aged 65 years or older who participated in the 8th Korea National Health and Nutrition Examination Survey (KNHANES) 2020. Characteristics of the high-risk group for OSA were investigated using the STOP-Bang questionnaire of the KNHANES data and were compared according to gender and age. The health status, metabolic variables, concurrent disease of the high risk group were compared with the control group. Results: In older adults aged 65 or older, snoring rates significantly decreased as their ages increased in both sex. The high risk group had a higher rate for performing strength exercise than control group. Depression showed a higher rate in the high risk group, but there was no difference in stress and quality of life in the two groups. The waist circumference and the prevalence of hypertension, stroke, dyslipidemia, diabetes, and metabolic syndrome was higher in the high-risk OSA group. Conclusion: It is unclear whether OSA-related symptoms increase with age in older adults over 65 years of age. Waist circumference was higher in the OSA high risk group, and this study showed that the OSA high risk group may be more likely to have metabolic syndrome and cardiovascular disease.
