The purpose of this study was to investigate relationships between low back pain (LBP) and psychological conditions in university wrestlers.
We examined psychological conditions of seventy male university wrestlers using the Psycholo gical Condition Inventory (PCI) test and evaluated whether psychological conditions have some relationships with LBP. Evaluations of LBP were based on a questionnaire test and the diagnosis of orthopedic surgeons. Based on the LBP evaluation, we assigned all wrestlers into two groups as the LBP group and the non-LBP group.
We obtained the following results. There were twenty-eight university wrestlers (40%) in the LBP group and forty-two wrestlers (60%) in the non-LBP group. Wrestlers in the LBP group showed significantly high values in all factors relating to fatigue in comparison to the non-LBP group.
We conclud that the university wrestlers with LBP feel fatigue in their minds and bodies.

Objective : To provide efficient medical care to patients taking warfarin by developing a system for sharing prothrombin time-international normalized ratio (PT-INR) monitoring data between clinic and pharmacy ; and to verify the functionality of this system.
Methods : Before a clinic appointment, patients visited a pharmacy to self-monitor PT-INR levels with the rapid measuring device Coagucheck. Pharmacists noted the following on a form shared between the clinic and the pharmacy : 1) compliance, 2) side effects, 3) diet, and 4) PT-INR. On the basis of this information, they noted their opinions on the appropriate warfarin dose. Each patient submitted the form to the clinic doctor, who then prescribed warfarin on the basis of the information recorded. After the consultation, the patient took this prescription to the pharmacy to obtain the required medication, and received from the pharmacist the dosage information based on the doctor's instructions. Thus, the sequence of the patient's visits was pharmacy-clinic-pharmacy.
Results : From one pharmacist's report, it was apparent that one patient whose PT-INR level was outside the target range was occasionally skipping a warfarin dose because of a misunderstanding about the treatment. The pharmacist recorded the patient's information on the form to inform the doctor. After consultation with the doctor, the pharmacist gave a detailed explanation on the purpose of taking warfarin. As a result, patient compliance improved and the PT-INR reached the target level after one month.
Discussion : Development of this system revealed that patients can receive appropriate warfarin treatment when information on PT-INR becomes available during clinical consultation and compliance is achieved. The system for sharing the patient's self-monitored PT-INR data between clinic and pharmacy is considered beneficial for the patient.

Background: Laparoscopy-assisted gastrectomy requires a lot of disposable products. So we compared the cost between laparoscopy-assisted gastrectomy and open surgery.Patients and methods: For comparison we used five cases each of open distal gastrectomy (ODG), laparoscopy-assisted distal gastrectomy (LADG), open total gastrectomy (OTG) and laparoscopy assisted total gastrectomy (LATG). In this study, we defined the profit of gastrectomy as below and we used the list price for all products. Profit of gastrectomy=Fee for gastrectomy-(Costs of all single use products-Demandable fee for single-use products)Results: Mean profits of ODG and LADG were 278,756.2 yen and 190,292.8 yen. The difference was 88,463.4 yen. Mean profits of OTG and LATG were 395,922.6 yen and 330,653.6 yen. The difference was 65,269 yen. Mean hospital charges, mean length of hospital stay, mean hospital charges per day of ODG, LADG, OTG and LATG were 1,390,464 yen, 21.4 days, 65,140.0 yen and 1,484,254.0 yen, 18.8 days, 80,805.4 yen and 1,956,664.0 yen, 24.4 days, 82,397.1 yen and 1,686,936.0 yen, 18.4 days, 91,894.8 yen, respectively.Conclusion: The turnover of laparoscopic gastrectomy was higher than open gastrectomy, but, the profit was lower because of high costs of disposable products. Hospital charges were not higher but the charge per day was higher because of a shorter hospital stay.

A 76-year-old woman with Stanford type A acute aortic dissection underwent replacement of the ascending aorta with the use of gelatin-resorcin-formalin glue. The patient suffered sudden cardiogenic shock at home 15 months after surgery and was admitted to the Emergency Center of our hospital. A series of examinations revealed an aortic-root pseudoaneurysm associated with anastomotic disruption. Cardiogenic shock caused by obstruction of the ascending aortic graft due to anastomotic disruption was diagnosed. An intraaortic balloon pump (IABP) was inserted, and the patient's circulatory status improved. On the following day, reanastomosis of the aortic root graft was performed. On day 32 after surgery, the patient was discharged from the hospital in good condition. IABP can stabilize circulatory status and improve cardiogenic shock in the short term in patients with an aortic-root pseudoaneurysm caused by narrowing of the graft lumen, as in the present patient. IABP may thus be a useful ancillary measure before radical operation.

Introduction: We report a case of intractable nausea of a terminal malignant lymphoma patient with diabetes, which improved by sublingual administration of asenapine. Case: A 78-year-old man suffering from diffuse large B-cell lymphoma with diabetes presented intractable nausea and vomiting. Those symptoms were thought to be due to masses and nodules in the right frontal lobe and the cerebellum, and/or due to edema in the peripheral brain parenchyma. Because it was difficult to take medicines orally, we selected injections to control those symptoms. However, the combination of metoclopramide, haloperidol, and hydroxyzine injections failed to relieve nausea. Olanzapine is effective against nausea but is contraindicated for diabetic patients, so asenapine, one of the multi-acting receptor-targeted antipsychotics the same as olanzapine, was expected alternatively. The patient was administrated asenapine sublingually 5mg once a day before bedtime. This administration of asenapine remarkably improved his nausea. Discussion: Sublingual asenapine dose may be an effective therapeutic option for intractable nausea.

Because the corona disaster made group medical training difficult, we conducted resuscitation training for new students and basic medical skills training for fourth-year students without face-to-face instruction using video learning, assessment, and ICT. In the resuscitation training, the students were allowed to take a mannequin home and film themselves performing the resuscitation while learning by video. Later, group and peer assessment were conducted via Zoom, and a significant increase in self-assessment was observed. In the basic medical skills training, the students filmed their own implementation at their own pace while learning by video, and the teachers later conducted video assessment and feedback. The lack of face-to-face instruction made it possible to implement the limb spine training, which had not been possible in previous years. It is necessary to adjust the timing of the video registration by the students and the video assessment by the teachers, and to make further improvements to the system.

To screen for additional treatment targets against tongue cancer, we evaluated the contributions of extracellular signal-related kinase (ERK), AKT and ezrin in cancer development. Immunohistochemical staining showed that ERK and ezrin expressions were significantly higher in invasive squamous cell carcinoma than in carcinoma in situ. To investigate the roles of ERK and ezrin in cancer development, we used the non-woven silica fibre sheet Cellbed with a structure resembling the loose connective tissue morphology in a novel 3D culture system. We confirmed that the 3D system using Cellbed accurately mimicked cancer cell morphology in vivo. Furthermore, cell projections were much more apparent in 3D-cultured tongue cancer cell lines than in 2D cultures. Typically, under conventional 2D culture conditions, F-actin and cortactin are colocalized in the form of puncta within cells. However, in the 3D-cultured cells, colocalization was mainly observed at the cell margins, including the projections. Projections containing F-actin and cortactin colocalization were predicted to be invadopodia. Although suppressing ezrin expression with small interfering RNA transfection caused no marked changes in morphology, cell projection formation was decreased, and the tumour thickness in vertical sections after 3D culture was markedly decreased after suppressing ERK activity because both the invasion ability and proliferation were inhibited. An association between cortactin activation as well as ERK activity and invadopodia formation was detected. Our novel 3D culture systems using Cellbed™ are simple and useful for in vitro studies before conducting animal experiments. ERK contributes to tongue cancer development by increasing both cancer cell proliferation and migration via cortactin activation.
