Objectives: To investigate the effect of the COVID-19 pandemic on surgical volume and outcomes in spine surgery., Design: A retrospective cohort study using prospectively collected data., Setting and Participants: A total of 9935 patients who underwent spine surgery between January 2019 and December 2021 at eight high-volume spine centres in the Greater Tokyo metropolitan area were included., Outcome Measures: The primary outcome measures were the number of surgical cases, perioperative complications and patient-reported outcomes, including numerical rating scales for each body part, Euro quality of life 5-dimension (EQ5D), Neck Disability Index and Oswestry Disability Index (ODI)., Results: The total number of surgeries in 2020 and 2021 remained lower than that of 2019, with respective percentages of 93.1% and 95.7% compared with the prepandemic period, with a marked reduction observed in May 2020 compared with the same period in 2019 (56.1% decrease). There were no significant differences between the prepandemic and postpandemic groups in the incidence of perioperative complications, although the frequency of reoperation tended to be higher in the postpandemic group (3.04% vs 3.76%, p=0.05). Subgroup analysis focusing on cervical spine surgery revealed significantly worse preoperative EQ5D scores in the postpandemic group (0.57 vs 0.54, p=0.004). Similarly, in lumbar spine surgery, the postpandemic group showed higher levels of leg pain (5.7 vs 6.1 to 0.002) and worse ODI scores (46.2 vs 47.7 to 0.02). However, postoperative outcomes were not different between pre and post-pandemic groups., Conclusions: The COVID-19 pandemic has significantly impacted spinal surgeries in Japan, leading to a decrease in surgical volumes and changes in patient characteristics and surgical procedures. However, surgical outcomes remained comparable between the pre and postpandemic periods, indicating the resilience and adaptability of healthcare systems., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Aim: The present study aimed to explore the need for information about permanent contraception in Japanese women with repeated cesarean sections (CS)., Methods: The present, cross-sectional survey used a self-administered questionnaire mailed to women with a second or later CS at Tokyo Metropolitan Tama Medical Center between March 2010 and December 2017. Those who were pregnant, had given birth less than 1 year before the survey or had an hysterectomy were excluded., Results: The present study analyzed 284 patients (60 with permanent contraception, 224 without permanent contraception). Forty-eight (80%) of women with permanent contraception, and 135 (60%) of women without permanent contraception believed that information on permanent contraception was needed before CS. Among women without permanent contraception, significantly fewer women obtained adequate information of permanent contraception from their healthcare workers before a CS compared with women with permanent contraception (8% vs. 71%, p < 0.001). A higher rate of unreliable contraceptive use (41%) and unintended pregnancies (4%) after the latest CS were found among the women without permanent contraception., Conclusions: A large portion of the study cohort wished they had received information on permanent contraception before CS; however, the patients without permanent contraception had limited access to this information. Adequate information about permanent contraception should be provided to women planning a CS to enable them to make an informed decision with respect to the treatment., (© 2020 Japan Society of Obstetrics and Gynecology.)

Background: Preventing and reducing frailty is an important challenge for Japan in the next decade, especially in metropolitan areas. We launched a community-wide intervention trial (the Ota Genki Senior Project) in 2016 to develop effective community-based strategies for frailty prevention in metropolitan areas. This report describes the study design and baseline survey., Methods: This study is a community-wide intervention trial that integrates participatory action research into a cluster non-randomized controlled trial for adults aged 65 years or older living in Ota City, Tokyo. We allocated 3 of 18 districts to an intervention group and the other 15 to a control group. Using a mailed self-administered questionnaire, we conducted a baseline survey of 15,500 residents (8,000 and 7,500 in the intervention and control groups, respectively) from July through August 2016. In addition to socioeconomic status and lifestyle variables, we assessed frailty status (primary outcome) and physical, nutritional, and psychosocial variables (secondary outcomes). Based on the baseline findings, an intervention to improve outcomes will be implemented as participatory action research. Follow-up surveys will be conducted in the same manner as the baseline survey., Results: A total of 11,925 questionnaires were returned (76.9% response rate; 6,105 [76.3%] and 5,820 [77.6%] in the intervention and control groups, respectively), and 11,701 were included in the analysis (mean age, 74.3 [standard deviation, 5.5] years; 48.5% were men)., Conclusions: This study is expected to contribute to development of a prototype of a community-wide frailty prevention strategy, especially in metropolitan areas in Japan., Trial Registration: UMIN Clinical Trials Registry (UMIN000026515).

Objectives　This study aimed to investigate the practice of eating alone, including its frequency, among urban older Japanese adults and to clarify its association with dietary variety.Methods　In June 2016, self-reported questionnaires were mailed to 15,500 men and women aged 65 years or older living in Ota City, Tokyo without nursing care certification. Of these, 11,925 questionnaires were returned (a 76.9% response rate), and responses from 8,812 subjects were analyzed (a 56.9% valid response rate). The frequency of eating alone, defined as the number of days per week eating alone for each meal, was reported as zero, one to three, four to six, or seven days. A Dietary Variety Score (DVS) was obtained based upon consumption frequencies per week of 10 food groups. Total points were calculated, and three or fewer points indicated low dietary variety. The association between eating alone and low dietary variety was analyzed by binomial logistic regression, with adjustments for potential confounding variables including age, body mass index (BMI), location, educational history, equivalent income, employment, living alone, medical history, and smoking and drinking habits.Results　The results indicated that 47.1% of men and 48.5% of women ate alone at least one day per week, and 14.9% of men and 16.9% of women ate alone every day. For men, after adjusting for potential confounders (ORs=1.51-2.00), the odds ratios (ORs) of low DVSs were significantly higher among those who ate alone one to three days, four to six days, or seven days per week compared to those who ate with others. For women, adjusted ORs were not significant among those who ate alone every day (OR=1.15, 95% CI=0.92-1.43). Men and women who ate alone had significantly lower ORs of eating green or yellow vegetables, fruits, and fats/oils almost every day compared to those who ate with others.Conclusion　Among urban Japanese older adults, about 50% of subjects reported eating alone. Eating alone was associated with lower dietary variety scores regardless of age, income, and family status. Therefore, the present findings might be useful for developing strategies for addressing undernutrition among urban older adults eating alone.

In Japan, admission to a psychiatric facility for people with schizophrenia is usually for life. We developed a rehabilitation program aimed at discharging these patients into the Tokyo community. This paper describes the results for the 224 patients. Using an inpatient ward at the Tokyo Musashino Hospital, patients were enrolled in the program and subsequently discharged into the community with an assigned worker. The results indicate for the majority (79%) re-integration into the community was successful. The success of this program in a metropolitan city like Tokyo argues for the efficacy of such programs.
