| Abstract | Several previous case reports have shown that patients with immunoglobulin D (IgD) multiple myeloma (MM) can be withdrawn from hemodialysis, however, the characteristics that can predict withdrawal in these patients have not yet been elucidated. A 57-year-old Japanese woman required hemodialysis because of renal dysfunction due to IgD-λ and Bence Jones protein-λ MM. Bortezomib-based chemotherapy nine days after admission led to her withdrawal from hemodialysis on Day 50. In our case-based review, younger age and early initiation of bortezomib-based chemotherapy emerged as possible predictors of successful hemodialysis withdrawal. |

| Abstract | Granulicatella species are rare, nutritionally variant streptococci that cause infective endocarditis. Their clinical and microbiological characteristics remain unknown. We reviewed five years of Granulicatella cases in our hospital database (Jan 2017-Jun 2022), finding 6 Granulicatella adiacens cases and 1 Granulicatella elegans case. Clinical backgrounds and bacteremia sources were diverse; 3 cases developed polymicrobial bacteremia. Antimicrobial testing showed non-susceptibility to penicillin G in 4 of 7 cases (57.1%), and high susceptibility to carbapenems and vancomycin in all cases. Determining optimal antibiotic therapy for Granulicatella infections is vital in this era of antimicrobial resistance. |

| Abstract | Rupture of the extensor pollicis longus (EPL) tendon is a known complication after undisplaced distal radius fracture (DRF). However, no report has revealed the relationship between EPL tendon rupture and the fracture pattern. Thus, this study aimed to investigate the characteristics of fractures at risk of EPL tendon rupture using fracture line mapping of undisplaced DRFs. This study used computed tomography imaging data of undisplaced DRFs with (n=18) and without EPL tendon rupture (n=52). Fracture lines obtained from 3D reconstruction data were drawn manually after matching with a 2D template wrist model. Fracture maps represented the fracture line distribution by superimposing the fracture lines of all 70 patients. Heat maps showed the relative frequency of the fracture lines as a gradual color change. Fracture lines of cases with EPL tendon rupture were concentrated in the proximal border of Lister’s tubercle. By contrast, fracture lines of cases without EPL tendon rupture were relatively dispersed. |

| Abstract | An intraoperative double-low condition is defined as concurrent low values for bispectral index (BIS) and mean arterial pressure (MAP), and may predict perioperative outcomes. We hypothesized that prolonged double-low times might be associated with an increased incidence of postoperative delirium. We conducted a single-center retrospective observational study on patients who had been admitted to our hospital’s intensive care unit (ICU) after surgery and whose BIS and MAP data had been recorded during general anesthesia. The primary outcome was the incidence of postoperative delirium. A double-low condition was defined as BIS < 45 and MAP <75 mmHg. The total double-low time was calculated in 1-min increments and used to divide the patients into quintiles. Multiple logistic regression analyses were conducted. Among the 334 patients included in the study, the incidence of postoperative delirium was 15.6% (n=52). Multiple logistic regression analysis revealed that a prolonged double-low time, defined as a total double-low time of > 42 min (i.e., third, fourth, and fifth quintiles), was significantly associated with an increased incidence of postoperative delirium (adjusted odds ratio: 2.61, 95% confidence interval: 1.27-5.37, p=0.009). Prolonged double-low time during general anesthesia was independently associated with an increased incidence of postoperative delirium in surgical ICU patients. |

| Abstract | The curriculum at the Department of Pathophysiology in the Periodontal Sciences program at Okayama University includes normative preclinical training (NPT) using phantoms. NPT is given to the whole class of 5 th year students divided in groups of 8 students/instructor. In 2019, an innovative personalized preclinical training (PPT) pilot study was implemented for this group of students whereby two students, each with their own dental unit, were coached by one instructor. The main topics covered were dental ergonomics and endodontics. We aimed to evaluate the effectiveness of PPT in dental ergonomics and endodontics toward increasing the knowledge and future clinical skills of students who had already undergone NPT. A test on endodontics was taken before and after PPT. A questionnaire was completed to assess their perception of improvement regarding the above-mentioned topics. Test scores and questionnaire results both showed that the students’ level of knowledge and awareness of future clinical skills was significantly higher after PPT. This pilot study demonstrated that PPT increased the students’ knowledge and future clinical skills. As preclinical training forms the foundation for clinical practice, investment in future research regarding this personalized approach is likely to enhance students’ understanding and clinical performance. |

| Abstract | We investigated the link between prolonged sedentary bouts and all-cause mortality in patients on chronic hemodialysis, using a prospective cohort. A total of 104 outpatients on chronic hemodialysis from 2013 to 2019, aged 71.4±11.4 years, were enrolled. Prolonged sedentary bouts (≥ 30 min and ≥60 min) (min and bouts) and relative prolonged sedentary bouts (≥ 30 min and ≥ 60 min) (%) on the patients’ non-hemodialysis days were measured by a tri-accelerometer, and we also analyzed the patients’ clinical parameters. The relationship between prolonged sedentary bouts and all-cause mortality was evaluated by a survival analysis and the Cox proportional hazard model. Thirty-five patients died during the follow-up period. A Kaplan-Meier analysis detected significant differences in the survival rate between two groups stratified by the median for all prolonged sedentary-bout parameters. After the adjustment for confounding factors, all of the prolonged sedentary-bout parameters were determinant factors for all-cause mortality. These results indicate that prolonged sedentary bouts on non-hemodialysis days were closely related to all-cause mortality in the patients on hemodialysis. |

| Abstract | Eating disorders (EDs) are associated with a high mortality rate. Patients with EDs often experience severe dehydration due to food restriction and/or vomiting. Severely underweight patients are often prescribed bed rest during inpatient care to reduce their energy consumption, and they may thus develop multiple risk factors for venous thromboembolism (VTE). We compared the clinical features of ED inpatients with VTE to those of ED inpatients without VTE. Seventy-one inpatients with ED were treated at Okayama University Hospital’s psychiatric ward in 2016-2020; five were experienced a VTE. Compared to the non-VTE group, the VTE group’s median age and disease duration were greater and the median body mass index (BMI) was lower. The VTE group’s D-dimer peak values were > 5 mg/L. Physical restraint and central venous catheter use were associated with VTE. Longer ED duration and lower BMI might be risk factors for VTE. To make inpatient treatment for ED safer, it is important to avoid the use of physical restraints and central venous catheters. Continuous D-dimer monitoring is necessary for the early detection of VTE in ED patients at high risk of VTE. |

| Abstract | Percutaneous cryoablation of renal tumors is widely used because of its high efficacy and safety. This high safety can be attributed, at least in part, to the visibility of the ablated area as an “ice ball”. This therapy has fewer complications (incidence, 0-7.2%) and is less invasive than surgery. Minor bleeding is inevitable in most kidney-related procedures, and indeed the most common complication of this therapy is bleeding (hematoma and hematuria). However, patients require treatment such as transfusion or transarterial embolization in only 0-4% of bleeding cases. Various other complications such as ureteral or collecting system injury, bowel injury, nerve injury, skin injury, infection, pneumothorax, and tract seeding also occur, but they are usually minor and asymptomatic. However, operators should know and avoid the various complications associated with this therapy. This study aimed to summarize the complications of percutaneous cryoablation for renal tumors and provide some techniques for achieving safe procedures. |

| Abstract | 本稿は，1970－2020年のベトナム経済における品質調整済み労働投入量（quality-adjusted labor input: QALI）の測定により，半世紀にわたる生産性の変化を分析することを目的としている。ベトナム経済の生産性統計の構築における最大の障壁は，同国SNA統計（VSNA）では雇用者報酬が推計されていないことである。本稿は，断片的な資料に基づきながらも，性，学歴，年齢，就業形態別のクロス分類によって定義された労働時間と賃金率の時系列データを構築し，QALIとともにミクロ的な基盤を持つ雇用者報酬と労働分配率の測定へと接近する。また2022年８月には2008 SNAに基づくVSNAが公表され，GDPは大幅な上方改定となった。新しい基準のVSNAに基づき1970年まで遡及した本稿での測定結果によれば，労働投入における質的改善のスピードは1970－2000年の年率0.6％から，2000－20年には（おもに学歴改善を通じて）年率2.0％へと加速し，それは同期間のQALI拡大の65％を牽引し，また労働生産性改善の14％を説明する要因となったと評価される。そしてベトナム経済で全要素生産性が改善を始めた時期は，旧基準に基づく分析結果よりも遅く，2010年代後半に顕著となったことが見出される。 |

| Title Alternative | Transnational Interregional Water Inducement Analysis between Japan and Mainland China and South Korea: The Analysis of Transnational Interregional Input-Output Table between Japan and Mainland China |
| FullText URL | oer_054_3_017_035.pdf |
| Author | Ishiro, Taku| |
| Abstract | When we analyze the international and interregional relation we need the Transnational Interregional Input-Output Table based on International Input-Output Table. At the moment Transnational Interregional Input-Output Table between Japan and China （TIIOT） made by IDE-JETRO provide the most useful information about these research. However, the regional classification of Japan in the table is not classified in detail such as Hokkaido, Tohoku, Kanto and so on. Therefore, the author divide Kanto area of TIIOT into 11 regions by information based on author's study （Ishiro （2011））. Furthermore, we divide the South Korea into 6 regions to expand our study and database. We analyze water footprint between Japan and mainland China and South Korea （Ishiro and Hasebe （2013））. Additionally, we expand our database to divide 7 region of mainland China into 30 regions by information of China multi-regional input-output table（ Ishiro and Yu（2016））. In this study we analyze the water inducement structures between Japan's Tokyo and Kanagawa and China's Beijing and Shanghai and South Koreaʼs Sudogwon by the database of Ishiro and Yu（2016） |

| Abstract | 本研究では中国の二酸化炭素（CO2）の排出量変化がどのような要因で生じたかについて，産業連関分析の手法である「比例成長からの乖離分析」（DPG分析）を用いて明らかにした。対象期間は，2007 ～ 2012年と2012 ～ 2017年の２期間である。 各産業の生産量変化の要因は，両期間を通じて消費と投資がプラス要因で輸出はマイナス要因であった。後半期には消費要因が急拡大し圧倒的なプラス要因になった。その一方で投資要因は縮小した。中国経済は輸出主導型から内需主導型に変化し，内需の中でも消費主導型に転換していることがわかった。CO2排出量変化の要因は，両期間を通じて技術変化と排出係数変化のよるCO2削減効果が大きかった。部門別には，電力・熱供給産業でのマイナスが大きく，その他の中国産業でも省電力が進展した。前半期と後半期とを比較すると，全産業のCO2排出DPGのマイナス幅は後半期で拡大しており，各産業それぞれで省エネが加速度的に進んだことがわかった。 |
