Objective:
The prognostic value and clinical usage of peritoneal cytology in endometrial cancer are uncertain. This study aimed to determine whether positive cytology is associated with the prognosis for endometrial cancer.
Methods:
A Japanese nationwide retrospective registry study was conducted between 2012 and 2019. Clinicopathological data were analyzed for patients who were registered in the Japan Society of Obstetrics and Gynecology (JSOG) gynecological tumor registry and underwent initial treatment for endometrial cancer.
Results:
In total, 83,027 patients who met the inclusion criteria were identified. Data on peritoneal cytology status and overall survival (OS) were available for 74,984 and 36,995 patients, respectively. Positive peritoneal cytology was found in 11,536 (15.4%) patients. A higher proportion of patients who had positive peritoneal cytology were related to advanced stages, high-grade histology, deep myometrial invasion, lymph node (LN) metastasis, and poor risk of recurrence. After controlling for age, stage, myometrial invasion, LN metastasis, distant metastasis, and risk of recurrence, positive peritoneal cytology was associated with poor prognosis (p<0.001). Multivariate Cox regression analysis revealed that clinicopathological factors (i.e., age, International Federation of Gynecology and Obstetrics stage, histological type, myometrial invasion, LN metastasis, distant metastasis, and peritoneal cytology), including positive peritoneal cytology, were also significant prognostic factors for OS.
Conclusion
Positive peritoneal cytology was a prognostic factor for endometrial cancer for the JSOG gynecological tumor registry.

Background:
Fertility preserving therapy using medroxyprogesterone acetate (MPA) is an important option for young patients with endometrial cancer or atypical endometrial hyperplasia (AEH). However, the effectiveness and feasibility of repeated MPA therapy for patients with intrauterine recurrence following initial MPA therapy is controversial. Only a few single-institution retrospective studies have been conducted on repeated MPA therapy, therefore, multicenter prospective studies for repeated MPA therapy are highly needed.The aim of this study is to assess whether repeated MPA therapy is effective and feasible for patients with intrauterine recurrence following initial MPA therapy.
Methods
This is a prospective, single-arm, a multicenter phase II trial on repeated MPA therapy for intrauterine recurrence following fertility-preserving therapy for AEH or stage IA (the International Federation of Gynecology and Obstetrics [FIGO] 2008) non-myoinvasive endometrioid carcinoma grade 1. Patients are treated with oral MPA (500–600 mg/day).Pathologically assessment via dilation and curettage will be performed every 2 months until complete response. The major inclusion criteria are 1) intrauterine recurrence of AEH or stage IA (FIGO 2008) endometrioid carcinoma grade 1 without myometrial invasion or extrauterine spread confirmed by imaging tests after complete remission with the previous MPA therapy. 2) The number of recurrences should be up to twice. 3) histologically diagnosed as AEH or endometrioid carcinoma grade 1, 4) 20–42 years of age, and 5) strong desire and consent for fertility-sparing treatment. The primary endpoint is 2-year recurrence-free survival rate. A total of 115 patients will be enrolled from multiple institutions in Japan and Korea within 4 years and followed up for 2 years.

People with high health knowledge tend to use information and communication technology (ICT) to obtain, maintain, and promote information necessary for health management. Therefore, experts hypothesize that improving health knowledge will increase the use of online medication guidance via ICT. In this study, we investigated the relationship between health knowledge and willingness to use online medication guidance among Iwaki Health Promotion Project health checkup subjects. The 736 examinees participating in this project in 2022 were surveyed on age, gender, number of people living with them, whether they exercise, drink alcohol, or smoke, whether they use smartphones, whether they use medication registers, their health knowledge score, and whether they take any medications. The presence/absence of desire for online medication guidance (1/0) was used as the objective variable to identify influencing factors. Univariate and multivariate analyses showed that independence was found for four factors: age (OR: 0.975, P<0.001), gender (male) (OR: 1.914, P<0.001), smartphone use (OR: 2.156, P=0.004) and health knowledge score (OR: 1.405, P<0.001). This study found that health knowledge plays a role in the intention to use online medication guidance. In order to improve health knowledge, it will be necessary to enhance skills to obtain and use high-quality health information and to improve the environment for using ICT-based communication devices.

Asian Spine Journal 2023;17(2):330-337
Methods:
A total of 79 patients with cervical myelopathy who underwent cervical laminoplasty at our facility between June 2010 and March 2013 were included in this study. Intraoperative control and final waveform were evaluated based on the trapezius muscle MEPs by measuring the latency and amplitude. A neck pain group comprised patients with higher neck pain Visual Analog Scale scores from preoperative value to 1 year postoperatively. The cross-sectional areas of the trapezius muscles and the MEP latencies and amplitudes were compared between patients with and without neck pain.
Results:
The latency and amplitude of the control waveforms were not significantly different between groups. The neck pain group had a significantly shorter final waveform latency (neck pain: 23.6±2.5, no neck pain: 25.8±4.5; p =0.019) and significantly larger amplitude (neck pain: 2,125±1,077, no neck pain: 1,630±966; p =0.041) than the no neck pain group.
Conclusions
Postoperative neck pain was associated with the final waveform latency and amplitude of the trapezius muscle MEPs during cervical laminoplasty. Intraoperative electrophysiological trapezius muscle abnormalities could cause postoperative neck pain.

Asian Spine Journal 2021;15(5):604-610
Methods:
The study included 100 patients with cervical myelopathy who underwent surgery at the National Center for Geriatrics and Gerontology in Obu, Japan from June 2010 to March 2013. Before the surgery, neck pain was evaluated using a Visual Analog Scale (a score ≥50 indicated neck pain and a score <50 indicated no neck pain). The preoperative cross-sectional areas of the trapezius muscles were measured with cervical magnetic resonance imaging sagittal T2-weighted images. Cranial stimulation under general anesthesia was used to derive the MEPs, enabling the measurement of latency and amplitude, using preoperative MEPs of the trapezius muscles.
Results:
The MEP of the trapezius muscle in patients with neck pain had significantly shorter latencies than those in patients who did not have neck pain. However, there was no significant difference in the amplitude between patients with and without neck pain. However, this tended to be greater in patients with neck pain as compared to that in those without neck pain. The cross-sectional area of the trapezius muscle in patients with neck pain was significantly smaller than that in those who did not have neck pain.
Conclusions
MEPs revealed electrophysiological abnormalities of the trapezius muscles in patients with neck pain, supporting a relationship of neck pain with the trapezius muscles.

OBJECTIVES: Sarcopenia and osteoporosis affects activities of daily living and quality of elderly people. However, little is known about its impact on elderly locomotor diseases, such as osteoporotic vertebral fracture (OVF). There is no report investigating the influence of both sarcopenia and osteoporosis on outcomes of OVF. This study aimed to evaluate the clinical outcomes of OVF in elderly patients from sarcopenic perspectives. METHODS: This prospective study was conducted with 396 patients, aged 65 years or more, hospitalized for the treatment of OVF (mean age, 81.9 ± 7.1 years; 111 males, 285 females). The primary outcome was the Japanese Orthopaedic Association (JOA) score for lumbar disease (at first visit, hospital discharge, and 1 year after treatment) and Barthel index (at the same time and before hospitalization). The second outcome was living place after discharge. Susceptibility to sarcopenia and osteoporosis were evaluated and clinical results of conservative treatment were compared. RESULTS: Sarcopenia significantly affected Barthel index at first visit and discharge. Sarcopenia patients had significantly higher rate for discharge to nursing home and living in nursing home after 1 year than patients without sarcopenia. Osteoporosis significantly affected the JOA score at the first visit and the Barthel index before hospitalization, at the first visit, discharge, and after 1 year. Osteoporosis did not affect the living place at discharge and after 1 year. CONCLUSIONS: Sarcopenia and osteoporosis affected outcomes of conservative treatment for OVF; moreover, sarcopenia affected the living place of OVF patients at discharge and after 1 year.
