Methods: Patients admitted for surgical treatment of CDD were recruited. The following patient-reported outcome measures were recorded on the day before the surgery: the Numerical Rating Scale (NRS) for neck pain intensity, Neck Disability Index (NDI), EuroQol 5-Dimensions (EQ-5D) survey, Central Sensitization Inventory (CSI), Pain Catastrophizing Scale, Tampa Scale for Kinesiophobia, and the Hospital Anxiety and Depression Scale were used. We performed three multiple regression analyses to investigate the effects of CSS and psychological factors on the clinical features. Results: Multiple regression analysis revealed that CSI had a significant effect on NRS (β, 0.50; 95% confidence interval [CI], 0.29 to 0.71), NDI (β, 0.64; 95% CI, 0.45 to 0.82), and EQ-5D (β, −0.55; 95% CI, −0.75 to −0.35). Multiple regression analysis revealed that psychological factors did not exert a significant effect on the clinical features. Conclusions Our results demonstrated that CSI was able to identify the clinical features in CDD patients, suggesting that CSS does affect the clinical features of such patients.

Objective: To determine the association between health-related quality of life (HRQOL) and neck pain, kinesiophobia, and modalities of physical activity in individuals with postoperative degenerative cervical myelopathy and radiculopathy (DCM/R) because postoperative pain after cervical spine surgery is likely to persist, causing kinesiophobia and avoidance of physical activity. Methods: A questionnaire was distributed to 280 individuals with DCM/R. The questionnaire comprised the following four items: HRQOL (EuroQol 5-dimensions 5-level), neck pain (numerical rating scale [NRS]), kinesiophobia (11-item Tampa Scale for Kinesiophobia [TSK-11]), and physical activity (paid work, light exercise, walking, strength training, and gardening). Hierarchical multiple regression analysis was performed using the NRS, TSK-11, and physical activity as independent variables. Results: In total, 126 individuals provided analyzable responses (45.0%). After including the NRS score as an independent variable to the multiple regression equation for participants’ background, the independent rate of the regression equation significantly improved by only 4.1% (R2=0.153). The addition of the TSK-11 score significantly improved this effect by 11.1% (R2=0.264). Finally, the addition of physical activity also significantly improved the explanatory rate by 9.9% (R2=0.363). Conclusion Neck pain, kinesiophobia, and physical activity (specifically paid work and walking) were independently associated with HRQOL in individuals with postoperative DCM/R.

PURPOSE: To analyze unusual events and focus discussion on pulmonary metastasis in particular after low-dose-rate brachytherapy (LDR-BT) for prostate cancer (PCa). MATERIALS AND METHODS: A total of 616 consecutive patients who had undergone LDR-BT for clinically localized PCa at Jikei University Hospital between October 2003 and April 2010 were enrolled in this study. Follow-up information was summarized, and patterns of biochemical recurrence and clinical outcome were investigated. RESULTS: Disease risk was stratified as low-risk in 231 patients, intermediate-risk in 365, and high-risk in 20, respectively. Of these patients, 269 (43.7%) had received hormonal therapy (HT) in combination with LDR-BT, and 80 (13.0%) had received external beam radiotherapy (EBRT). Average dosimetric parameter values with and without EBRT were 95.3% and 94.2% for V100, 132.8 Gy and 164.2 Gy for D90, and 180.6 Gy2 and 173.7 Gy2 for the biologically effective dose. Biochemical recurrence was noted in 14 patients (6.1%) in the low-risk group, 25 patients (6.8%) in the intermediate-risk group, and 6 patients (30.0%) in the high-risk group, respectively. In these cases of biochemical recurrence, 9 (64.3%), 13 (52.0%), and 4 patients (66.7%) in each respective risk group showed signs of clinical recurrence. Five patients (19.2%) with clinical recurrence developed pulmonary metastases, of which 4 were isolated lesions. All tumors responded favorably to subsequent HT. CONCLUSIONS: LDR-BT for biologically aggressive PCa may be linked to possible pulmonary metastasis owing to tumor dissemination during seed implantation. This information is important in planning adequate treatment for these patients.

The system of the Japanese Board of Cardiovascular Surgery is changing. Since the last time, we have deliberated on the medical specialty board for U-40 column articles about the problems faced by young cardiovascular surgeons. This time, we conducted the second survey to U-40 members about the realities of becoming a board-certified cardiovascular surgeon. The results showed the circumstances and details on how to acquire the board certification. Moreover, we discussed about the current problems and future perspectives for the young cardiovascular surgeons.

The first examination of the new board of the Japanese cardiovascular surgery took place in 2022. As it is a transitional period for the new system, many doctors are not familiar with the changes and details of the new system, and some have their concerns. Here, we held a round-table discussion with doctors who actually took the new board of the Japanese cardiovascular surgery under the new system, and we summarized their opinion.
