The use of arts in Japanese health professions education has received increasing attention. This paper provides an overview of arts-integrated learning and related concepts, including medical humanities. It also discusses the benefits of using arts as a new teaching method. The benefits include facilitating the understanding of the human condition-such as involvement in medicine and disease-with emotion, including empathy, through case studies and cultivating perspective-taking and critical perspectives. Further, the use of arts helps to encourage learning in diverse contexts for transfer (application) to clinical practice, fostering values regarding medicine, nurturing a research mindset, facilitating an integrative understanding using creative methods, and enabling students to experience the usefulness of arts in medicine.

Objectives: Behavioral restrictions and staying at home during the COVID-19 pandemic have affected lifestyles. It was hypothesized that patients with rheumatoid arthritis (RA) decreased their activities of daily living (ADL) and exercise during the pandemic. The aim of this study is to investigate the changes in lifestyle and body composition. Methods: Data were obtained from an observational study (CHIKARA study). Of 100 RA patients, 70 (57 women, 13 men) were followed-up with measurements of grip strength, as well as muscle mass, fat mass, and basal metabolic rate by a body composition analyzer. Changes in ADL and exercise were evaluated using a visual analog scale. The relationships between changes in ADL or exercise and body composition were investigated. Results: Muscle mass and grip strength were significantly lower after behavioral restrictions compared to the periods before restrictions (34.0 vs 34.7 kg, P < 0.001; 16.2 vs 17.2 kg, P = 0.013, respectively). Fat mass was significantly greater after behavioral restrictions compared to the periods before restrictions (16.2 vs 15.5 kg, P = 0.014). The mean decrease in ADL was 44%, whereas that of exercise was 20%.The change in muscle mass (β = −0.335, P = 0.007) was the only independent factor for the change in exercise on multivariate analysis. Conclusions Muscle mass and grip strength decreased and fat mass increased in RA patients with the behavioral restrictions of the COVID-19 pandemic. Muscle mass decreased in patients without exercise. Maintenance of muscle mass may be important during the COVID-19 pandemic.

Background: To evaluate the clinical outcomes and second-look arthroscopic findings after intra-articular adipose-derived regenerative cell (ADRC) injection as treatment for knee osteoarthritis (OA). Methods: ADRCs were administered to 11 patients (19 knees; mean age, 61.7 years) with knee OA. Subcutaneous adipose tissue was harvested by liposuction from both thighs, and arthroscopic lavage was performed, followed by ADRC injection (mean dose, 1.40 × 10 7 cells) into the synovial fluid. Outcome measures included the Knee Injury and Osteoarthritis Outcome Score, Lysholm score, and visual analog scale score. Arthroscopic examinations were performed to assess the International Cartilage Repair Society cartilage injury grade preoperatively and overall repair postoperatively. Noninvasive assessments were performed at baseline and at 1-, 3-, and 6-month follow-ups; arthroscopic assessments were performed at baseline and at 6 months. Results: All outcome measures significantly improved after treatment. This improvement was evident 1 month after treatment and was sustained until the 6-month follow-up. Data from second-look arthroscopy showed better repair in low-grade cartilage lesions than in lesions with a greater degree of damage. No patients demonstrated worsening of Kellgren-Lawrence grade, and none underwent total knee arthroplasty during this period. Conclusions Clinical outcomes were improved in patients with knee OA after ADRC administration. Cartilage regeneration was more effective in smaller damaged lesions than in bigger lesions.

Purpose: Most studies have investigated the differences in postgastrectomy quality of life (QOL) based on the surgical procedure or reconstruction method adopted; only a few studies have compared QOL based on tumor location. This large-scale study aims to investigate the differences in QOL between patients with esophagogastric junction cancer (EGJC) and those with upper third gastric cancer (UGC) undergoing the same gastrectomy procedure to evaluate the impact of tumor location on postoperative QOL. Methods: The Postgastrectomy Syndrome Assessment Scale-45 (PGSAS-45) questionnaire was distributed in 70 institutions to 2,364 patients who underwent gastrectomy for EGJC or UGC.A total of 1,909 patients were eligible for the study, and 1,744 patients who underwent total gastrectomy (TG) or proximal gastrectomy (PG) were selected for the final analysis. These patients were divided into EGJC and UGC groups; thereafter, the PGSAS-45 main outcome measures (MOMs) were compared between the two groups for each type of gastrectomy. Results: Among the post-TG patients, only one MOM was significantly better in the UGC group than in the EGJC group. Conversely, among the post-PG patients, postoperative QOL was significantly better in 6 out of 19 MOMs in the UGC group than in the EGJC group. Conclusions Tumor location had a minimal effect on the postoperative QOL of post-TG patients, whereas among post-PG patients, there were definite differences in postoperative QOL between the two groups. It seems reasonable to conservatively estimate the benefits of PG in patients with EGJC compared to those in patients with UGC.

Background and objectives: The number of workers taking temporary leave due to clinical depression is increasing, and the probability that these workers will take such leave again after returning to work is high. In response to this dilemma, institutions involved in psychiatric care across Japan now implement “rework programmes,” aiming to help employees resume work without relapsing to depression. Methods: This programme has several forms. Between May 2017 and June 2019, 32 patients on temporary leave due to a depressed mood participated in group psychotherapy at our clinic. Of these patients, 21 patients who were able to return to work without a recurrence of symptoms, evaluated upon reinstatement, and followed up for 1 year were analysed in this study. The participants were divided into two groups: a continued employment group (n=16) consisting of patients who were still working one year after reinstatement and a repeat leave group (n=5) consisting of those who took temporary leave again within the first year. Differences in psychiatric symptoms, social function, cognitive function, readiness to return to work, and other factors were compared between the two groups. Results: The continued employment group was likely to have better social function, cognitive flexibility, and executive function when returning to work. Conclusion These preliminary results indicate that social functions and cognitive functions might be associated with continued employment.

Methods: Study participants comprised five healthy volunteers (mean age, 27.2 years) and 27 patients with LSS (mean age, 58.4 years) who were individually assessed using 3.0 Tesla magnetic resonance imaging. Intraspinal ADC and FA values of 10 intervertebral discs from healthy volunteers and 52 intervertebral discs from LSS patients were measured. Also, intraspinal canal area, Schizas classification (A: normal, B: mild stenosis, C: severe stenosis) and correlations with symptoms were investigated. Clinical symptoms were checked for the presence of low back pain (LBP), intermittent claudication (IMC), and bladder and bowel dysfunction (BBD). Results: Compared to healthy individuals, LSS patients had significantly lower ADC (p<0.05) and significantly higher FA values (p<0.01). In Schizas classification, stenosis worsened from A to C. ADC values decreased significantly while FA values increased significantly in that order (p<0.05). A positive correlation was found between intraspinal canal area and ADC values (r=0.63, p<0.01) and a negative correlation between intraspinal canal area and FA values (p=−0.61, p<0.01). No correlations were noted between LBP and ADC or FA values. On the other hand, ADC values were significantly lower (p<0.05) and FA values were significantly higher (p<0.05) in patients with IMC or BBD. Conclusions Intraspinal DTI parameters such as ADC and FA values were associated with the Schizas classification, intraspinal canal area, and clinical symptoms, suggesting that ADC and FA may be useful for quantitative assessment of LSS.

Objectives: Osteosarcopenia is defined as osteoporosis with sarcopenia. The impacts of osteosarcopenia on falls and fractures in rheumatoid arthritis (RA) patients were investigated using 4 years of data from a longitudinal study (CHIKARA study). Methods: The patients were divided into 4 groups by their baseline status: no sarcopenia and no osteoporosis (SP-OP-); only sarcopenia (SP + OP-); only osteoporosis (SP-OP+); and both sarcopenia and osteoporosis (SP + OP+). Survival rates and Cox hazard ratios were analyzed using falls and fractures as endpoints, adjusted by age, sex, and body mass index. Results: A total of 100 RA patients (SP-OP-: 44%, SP + OP-: 17%, SP-OP+: 28%, and SP + OP+: 11%) were enrolled; 37 patients had falls, and 19 patients had fractures. The fall-free and fracture-free survival rates were significantly lower in SP + OP+ (36.4%, 54.5%) than in SP-OP- (75.0%, 86.4%). The hazard ratio of falls was significantly increased in SP + OP+, by 3.32-fold (95%CI: 1.01–10.9), whereas in SP + OP- and SP-OP+, there were no differences compared to SP-OP-. Conclusions The survival rates with the endpoints of falls and fractures in RA patients with osteosarcopenia were lower during 4-year follow-up. The risk of falls increased with the synergistic effect of osteoporosis and sarcopenia.

Palmoplantar pustulosis is a chronic inflammatory skin disease involving the palms and soles where mild accumulation of helper T cells and neutrophils in the dermis histologically are observed. Leukoencephalopathy is a brain disease affecting white matter but is rarely accompanied by skin lesion. Here we report a unique case of leukoencephalopathy accompanied by palmoplantar pustulosis with identical pathological feature of helper T cell accumulation in both the brain and skin, suggesting a possible link in the pathogenesis.

Methods: We performed 3T MRI in 10 healthy volunteers and 13 patients with LSS. The ADC values in the spinal canal were evaluated at 46 vertebrae (L4/5 and L5/S1 for each participant), and the reduced and conventional fields of view were compared. Results: The ADC values were 2.72±0.12 at L4/5 in healthy volunteers, 2.76±0.19 at L5/S1 in healthy volunteers, 1.77±0.58 at L4/5 in patients with LSS, and 2.35±0.29 at L5/S1 in patients with LSS. The ADC value at L4/5 in patients with LSS was significantly lower than that at L5/S1 in patients with LSS and that at L4/5 and L5/S1 in healthy volunteers (p <0.05). With an ADC cutoff value of 2.46 to identify LSS, this approach provided an area under the curve of 0.81, sensitivity of 0.92, and specificity of 0.76 (p <0.05). Conclusions Preoperative examination using ADC maps permits visualization and quantification of spinal canal lesions, thus proving the utility of ADC maps in the selection of decompression surgery for LSS.
