Abstract
Japan has a high suicide mortality rate compared to other developed countries. To reduce suicide mortality in Japan, it is important to systematically analyze factors related to death of patients with suicide attempt. This study aimed to analyze the characteristics of patients with suicide attempt, and the factors related to their death using the Diagnosis Procedure Combination (DPC) data- a nationally representative inpatient database. We collected 81,407 cases of suicide attempt from 2016 to 2018 from DPC data and performed a multilevel logistic analysis of factors associated with death discharges. The analysis results showed that patients who received psychiatric liaison care had a lower mortality rate, but only 0.6% of surviving patients received psychiatric liaison care after admission. The odds ratio (OR) of death was high for hanging (28.86; p < 0.001) and jumping (16.28; p < 0.001), compared to wrist cutting. Patients without a psychiatric diagnosis were more likely to choose means such as hanging (14.1%) than those with a psychiatric disorder. The weekend cases had a higher OR of death than weekday (Wednesday as reference) cases (Friday 1.14, p = 0.011; Saturday 1.60, p < 0.001; Sunday 1.67, p < 0.001). Based on these findings, we suggest that improving the availability and quality of psychiatric care in acute care hospitals and primary care settings, as well as enhancing the emergency department system on weekends, could help reduce the mortality of suicide attempts.

Abstract
BACKGROUND No clear evidence exists regarding the effects of the different periods and magnitude of spread of the COVID-19 infection on cancer treatments. This study investigated the effects of the different periods and magnitude of COVID-19 infection spread on in-hospital cancer operations. METHODS Medical claims data from 17 hospitals where in-hospital operations for patients with malignant neoplasms were performed between 1 April 2017 and 31 March 2021 in Yamagata were extracted and analyzed. The critical time points as exposure used to evaluate the impact of different COVID-19 infection spread periods on cancer operations were (1) April 2020 (emergency declaration introduced by the government) and (2) December 2020 (the second wave). From April to November 2020 and December 2020 to March 21, the number of confirmed COVID-19 cases was 130 and 840, respectively. The 17 hospitals were classified into intervention or control groups based on whether in-hospital treatments for patients with COVID-19 were provided. RESULTS The interrupted time series analysis reported that the difference in the trend of pre-COVID-19 and postsecond wave (March 2020 to December 2020) periods was statistically significant between groups, with 50.67 fewer operations (95% confidence interval [CI] = 12.19-89.15) performed per month in the intervention group compared with the control group. Moreover, the immediate change in the number of operations in April 2020 (beginning of the first wave) was statistically significant between groups, with 80.14 operations (95% CI = 39.62-120.67) less immediately after the first wave in the intervention group compared with the control group. CONCLUSION Our findings suggest that a statement of emergency by the government and the COVID-19 infection spread are both associated with the number of cancer operations performed in the Yamagata prefecture during the COVID-19 pandemic.

Abstract
To diagnose chronic kidney disease (CKD) at an early stage, it is important to promote appropriate health guidance and consultation recommendations through regular medical examinations and implementation of continuous high-quality and appropriate treatment. From fiscal year (FY) 2018, Izumo City has initiated the “Izumo City CKD Exacerbation Countermeasures” program. In this study, we aimed to report on the methods undertaken and the effects of this program. Residents aged 40–74 years who underwent specific health checkups from the Izumo City National Health Insurance in FY2018 and FY2019 were included. The rates of CKD re-examination candidates, re-examinations implementation, nephrologist referrals, and health guidance referrals between FY2018 and FY2019 were compared. The rate of CKD re-examination candidates in both years remained unchanged at approximately 7%. The rate of re-examination implementation in FY2019 significantly increased relative to that in FY2018 (p < 0.001). Subsequent re-examination candidate trends showed that the rate of nephrologist referrals did not increase. However, the rate of city health guidance referrals significantly increased (p < 0.001). Increase in the re-examination and health guidance examination rates indicate improved awareness of CKD among the public and family doctors, and it is expected to prevent CKD exacerbation in the future.

Abstract
Objective Based on the findings of preferable outcomes from recanalization therapy in recent studies, regional partnerships for the endovascular treatment of acute ischemic stroke are being promoted. However, reports of inter-island cooperation between remote islands located far from high-volume centers on the mainland are rare. Case Presentation A 63-year-old man experienced an acute ischemic stroke on a small, isolated island in Okinawa, Japan. He was transferred by helicopter to the primary emergency hospital on Ishigaki Island, which was the nearest island on which he could be administered recombinant tissue plasminogen activator (rtPA). After this, he was carried again by helicopter and ambulance to the primary stroke center on Miyako Island using the drip and ship method. Mechanical thrombectomy with a stent retriever achieved recanalization of the occluded major vessels and improved the neurological disturbance. The patient became neurologically independent and could be discharged only 11 days after onset. Conclusion Building a local area network that includes hospitals providing mechanical thrombectomy is a meaningful approach to treating acute ischemic stroke occurring on isolated islands. It is necessary to recognize the specific restrictions imposed by helicopter transportation and to make efforts to shorten the time required for key processes to provide faster treatment.

Abstract
In recent years, with the increase in degenerative diseases and the aging population in advanced countries, demands for medical care of older or solitary people have increased continually in hospitals and healthcare institutions. Applying wireless sensor networks for the IoT-based telemedicine system enables doctors, caregivers or families to monitor patients' physiological conditions at anytime and anyplace according to the acquired information. However, transmitting physiological data through the Internet concerns the personal privacy of patients. Therefore, before users can access medical care services in IoT-based medical care system, they must be authenticated. Typically, user authentication and data encryption are most critical for securing network communications over a public channel between two or more participants. In 2016, Liu and Chung proposed a bilinear pairing-based password authentication scheme for wireless healthcare sensor networks. They claimed their authentication scheme cannot only secure sensor data transmission, but also resist various well-known security attacks. In this paper, we demonstrate that Liu-Chung's scheme has some security weaknesses, and we further present an improved secure authentication and data encryption scheme for the IoT-based medical care system, which can provide user anonymity and prevent the security threats of replay and password/sensed data disclosure attacks. Moreover, we modify the authentication process to reduce redundancy in protocol design, and the proposed scheme is more efficient in performance compared with previous related schemes. Finally, the proposed scheme is provably secure in the random oracle model under ECDHP.

Abstract
In this study, we have analyzed both administrative and clinical data from our hospital during 2002 to 2012 to evaluate the influence of government medical policies on reducing abandonment treatment in pediatric patients with acute lymphoblastic leukemia. Two policies funding for the catastrophic diseases and the new rural cooperative medical care system (NRCMS) were initiated in 2005 and 2011, respectively. About 1151 children diagnosed with acute lymphoblastic leukemia were enrolled in our study during this period and 316 cases abandoned treatment. Statistical differences in sex, age, number of children in the family, and family financial status were observed. Of most importance, the medical insurance coverage was critical for reducing abandonment treatment. However, 92 cases abandoning treatment after relapse did not show significant difference either in medical insurance coverage or in duration from first complete remission. In conclusion, financial crisis was the main reason for abandoning treatment. Government-funded health care expenditure programs reduced families' economic burden and thereby reduced the abandonment rate with resultant increased overall survival.

Abstract
OBJECTIVES The author conducted an ecological study to examine prefectural differences in ENMR and the related factors in Japan, using two new indicators; birth weight (BW) adjusted ENMR and expected ENMR by BW distribution. METHOD Correlate analysis of data from national vital statistics and some indicators of medical care services among 47 prefectures edited by the Ministry of Health and Welfare, Japan were conducted. BW-adjusted ENMR and expected ENMR by BW, as well as other indicators, were prepared for statistical analysis. RESULT Crude and BW-adjusted ENMRs were significantly correlated with ENMRs for low birth weight (LBW) and very low birth weight (VLBW) early neonates (p<0.01). The number of Obstetrics and Gynecology (OB/GYN) physicians was negatively correlated with BW adjusted ENMR. CONCLUSION Crude and BW-adjusted ENMRs were affected mainly by LBW and VLBW early neonate specific ENMR, but not by the rate of LBW. The variation of ENMR among prefectures in Japan is attributable to the number of OB/GYN physicians. The present findings suggest that emphasis should be laid upon enhancement of regional perinatal care systems.
