| Abstract | The notion of weakly separable extensions was introduced by N. Hamaguchi and A. Nakajima as a generalization of separable extensions. The purpose of this article is to give a characterization of weakly separable polynomials in skew polynomial rings. Moreover, we shall show the relation between separability and weak separability in skew polynomial rings of derivation type. |

| Abstract | Let G be a finite group. In 1970s, T. Petrie defined the Smith equivalence of real G-modules. The Smith set of G is the subset of the real representation ring consisting of elements obtained as differences of Smith equivalent real G-modules. Various results of the topic have been obtained. The d-Smith set of G is the set of all elements [V ]−[W] in the Smith set of G such that the H-fixed point sets of V and W have the same dimension for all subgroups H of G. The results of the Smith sets of the alternating groups and the symmetric groups are obtained by E. Laitinen, K. Pawa lowski and R. Solomon. In this paper, we give the calculation results of the d-Smith sets of the alternating groups and the symmetric groups. In addition, we give the calculation results of the d-Smith sets of Cartesian products of the alternating groups and finite elementary abelian 2-groups. |

| Abstract | Among studies evaluating minimally invasive surgical (MIS) decompression of the L5 root, techniques involving transtubular endoscopic decompression under O-arm navigation are rare. We present the case of a 68-yearold woman with left leg pain, muscle weakness and gait disturbance of one month duration. The patient underwent transtubular endoscopic decompression under O-arm navigation. There is no radiation hazard to the operating room staff with this procedure. After surgery, the patient had significant pain relief and her left lower limb motor function had improved by follow-up at one year. C-arm-free endoscopic L5 root decompression is a safe and effective procedure. |

| Abstract | Anorexia nervosa (AN) is occasionally complicated with hypoglycemic coma, which may cause sudden death by unknown mechanisms. We present the case of a 36-year-old woman with recurrent comas and a nineteen-year history of AN. She was found in a coma with remarkable hypoglycemia (28 mg/dL). Her BMI was 11.1 kg/m2. Endocrine workup revealed extremely low serum levels of glucagon, IGF-I and insulin. Asymptomatic hypoglycemia occurred with liver injury in the refeeding process. An aberrant glucose metabolism due to liver damage might have been involved in her susceptibility to hypoglycemia. This case suggests a possible mechanism of hypoglycemic coma in AN. |

| Abstract | A 77-year-old Japanese woman who had been treated for follicular lymphoma for 8 years developed abdominal pain and intra-abdominal lymphadenopathies. Colonoscopy revealed an elevated lesion in the rectum, which presented as two humps with erosions. A diagnosis of histologic transformation of follicular lymphoma to diffuse large B-cell lymphoma was made by endoscopic biopsy. This case underscores the importance of endoscopy examinations and biopsy of newly emerged gastrointestinal lesions for the prompt diagnosis of histologic transformation, since salvage chemotherapy must be initiated quickly in such cases. |

| Abstract | Family members are critical mediators of the experiences of transgender people. We studied whether transgen-der subjects had disclosed their identity to their families and their families’ reactions after the disclosure. We also evaluated the subjects’ mental state and its association with disclosure status. Transgender people were recruited for this anonymous questionnaire survey in the Okayama University Hospital gender clinic. Subjects disclosed their identity to family members at the following rates: 68.7% to the father, 89.1% to the mother, 59.1% to a brother, 77.8% to a sister, and 47.6% to grandparents. Fathers had the lowest rate (26.7%) of posi-tive reactions, while over 50% of fathers showed an ambiguous response. Approximately 20% of parents showed a negative response. The majority of parents agreed to hormonal treatment and sex-reassignment sur-gery and that the transgender child should live with the gender they wanted to express. However, the rate of subjects with mood and anxiety disorders according to the Kessler 6 scale was significantly higher in those who experienced negative or ambiguous reactions from family members compared to those who experienced posi-tive reactions. Educational and mental health professionals should support the disclosure process of transgen-der people as well as their family members. |

| Abstract | Research suggests that the fundamental concepts of epidemiology cannot be sufficiently learned in traditional lectures, and interactive learning is necessary. However, few studies have investigated interactive epidemiology education in general, or peer instruction (PI) in particular. This study investigated the effect of PI. Study par-ticipants were fourth-year medical students. The attitude of participants in regard to PI learning was examined in a non-PI and a PI group. The Survey of Attitudes Toward Statistics (SATS) (containing six sub-categories) was conducted as a learning-attitudes index. The pre- and post-lecture scores were compared between the non-PI and PI groups using double robust (DR) estimation. The non-PI and PI groups consisted of 20 and 121 student participants, respectively. In DR estimation, affect exhibited the lowest SATS score changes, at −0.51 (95% confidence interval −0.78 to −0.24; p-value < 0.001), whereas effort exhibited the highest score changes of 0.01 (95% confidence interval −0.30 to 0.32; p-value = 0.952). The epidemiology lecture with PI did not increase the SATS scores. This might be due to issues related to the experimental design. Further research investigating the effects of interactive epidemiology education, it will be necessary to develop tools for assessing the learning of epidemiological concepts and to improve the research design. |

| Abstract | Multidisciplinary approaches such as fracture liaison services (FLS) have been introduced in some countries to reduce medical complications and secondary fractures in patients with fragility hip fracture. We aimed to investigate outcomes in patients with fragility hip fracture following the introduction of FLS. Patients > 50 years old who experienced fragility hip fractures between January 1, 2015 and December 31, 2017 were enrolled, and divided into a control group (without FLS; 94 patients) and FLS group (373 patients). We found that the time from injury to surgery decreased significantly from 2.42 to 1.83 days (p = 0.003), the proportion of patients who underwent surgery within 36 h of injury increased significantly (p = 0.014), and the number of cases with complications after admission decreased significantly (p = 0.004) in the FLS group. Patients with a Barthel index ≥ 80 were more common in the FLS than the control group at 6 , 12, and 24 months following injury (p = 0.046 , 0.018, and 0.048, respectively). Multiple logistic regression analysis revealed the factors associated with postoperative complications and death within 12 or 24 months after injury. Our results indicate that FLS contributed to earlier recovery, rehabilitation following surgery and rehabilitation of medical complications following admission; improved patient activity; and decreased secondary hip fractures. |

| Abstract | Many patients develop acute kidney injury (AKI) after vascular surgery. In this retrospective observational study, we investigated the risk factors for AKI defined using the Kidney Disease Improving Global Outcomes criteria after total arch replacement (TAR). Additionally, we investigated the influence of temperature manage-ment during cardiopulmonary bypass (CPB) on postoperative renal function by propensity score-matched anal-ysis. We retrospectively analyzed 161 consecutive patients who underwent TAR between 2016 and 2019. Postoperative AKI occurred in 48.7% of the patients. In the multivariate analysis, male sex (odds ratio [OR] 3.95, 95% confidence interval [95%CI] 1.56-8.27, p = 0.002), ACE inhibitors/ARB medication (OR 3.19, 95%CI 1.49-6.82, p = 0.003), preoperative chronic kidney disease (OR 2.47, 95%CI 1.17-5.23, p = 0.02), pro-longed CPB time (OR 2.36, 95%CI 1.05-5.34, p = 0.04), and lower body ischemic time during CPB (OR 2.20, 95%CI 1.05-4.46, p = 0.04) were identified as independent risk factors for AKI. Propensity score-matched anal-ysis showed no significant difference in the risk of AKI following TAR between mild hypothermia or normo-thermia and moderate hypothermia (37.2% vs. 41.9%, p = 0.83). In conclusion, modifiable risk factors for AKI included prolonged CPB time and lower body ischemic time. Temperature management during CPB had no clear effect on outcomes. |

| Abstract | HipCOMPASS, a mechanical intraoperative support device used in total hip arthroplasty (THA), improves the cup-alignment accuracy. However, the alignment accuracy achieved by HipCOMPASS has not been specifically examined in obese patients. In this study, we retrospectively evaluated the relation between alignment accuracy and several obesity-related parameters in 448 consecutive patients who underwent primary THA using HipCOMPASS. We used computed tomography (CT) to measure the preoperative soft-tissue thickness of the anterior-superior iliac spine (ASIS) and pubic symphysis and the differences between preoperative and postoperative cup angle based on the cup-alignment error. We found significant correlations between the absolute value of radiographic anteversion difference and body mass index (r = 0.205), ASIS thickness (r = 0.419), and pubic symphysis thickness (r = 0.434). The absolute value of radiographic inclination difference was significantly correlated with ASIS (r = 0.257) and pubic symphysis thickness (r = 0.202). The receiver operating characteristic curve showed a pubic symphysis thickness of 37.2 mm for a ≥ 5° implantation error in both radiographic inclination and anteversion simultaneously. The cup-alignment error for HipCOMPASS was large in patients whose pubic symphysis thickness was ≥ 37.2 mm on preoperative CT. Our results indicate that methods other than HipCOMPASS, including computed tomography-based navigation systems, might be preferable in obese patients. |

| Abstract | Influenza potentially has a high mortality rate when it affects the elderly. We aimed to examine the differences in clinical manifestations in patients with influenza according to their age. This multicenter prospective study was performed in six medical institutions in Okayama and Kagawa prefectures (Japan). Between December 1, 2019 and March 31, 2020, we collected data on adult patients diagnosed with influenza type A, who were strat-ified into younger (20-49 years), middle-aged (50-64 years), and older groups (≥ 65 years). We compared the presence or absence of fever, respiratory symptoms, and extrapulmonary symptoms according to age group. In total, 203 patients (113, younger; 51, middle-aged; and 39, older) were eligible for the analysis. The maxi-mum body temperature and temperature at first physician visit in the older group were significantly lower than those in the younger group. The incidence of respiratory symptoms was not different among the three groups. Chills, muscle pain, and arthralgia as systemic symptoms were noted significantly more frequently in the younger (80.9%) and middle-aged (75.5%) groups than in the older group (51.3%) (p = 0.002). Fever and sys-temic symptoms were less likely to appear in older patients, possibly resulting in the delaying of hospital visits among older adults. |

| Abstract | This study examined the relationship between skin physiological indices and pressure ulcers in elderly people. The subjects were 55 bedridden elderly Japanese patients with a median age of 85 years. The following parame-ters were measured using non-invasive devices: skin surface temperature, moisture content in the stratum corneum, moisture content in the dermis, transepidermal water loss as an index of skin barrier function, skin erythema and skin elasticity. The sacral and 2 heel areas were observed as sites predisposed to pressure ulcers. Within one month after measuring the skin physiological indices, we confirmed pressure ulcers of National Pressure Ulcer Advisory Panel classification Stage II or worse based on medical records. Among the 55 patients, 4 (7.3%) prospectively developed a total of 5 pressure ulcers within 16 days. Only the skin erythema score was significantly higher with than without pressure ulcers (p < 0.001). We performed a binary logistic regression analysis and confirmed a significant relationship between pressure-ulcer development and the level of erythema (odds ratio = 1.026; 95% confidence interval: 1.011-1.042). Skin erythema increased before the development of pressure ulcers. Taken together, our results show that the high skin erythema score can be a predictive indicator of pressure ulcers. |
