    Abstract The Physical Activity Guidelines for Americans, second edition recommends that older adults do multicomponent physical activity, which includes balance training in addition to aerobic and muscle-strengthening activities. The authors estimated the prevalence of U.S. older adults (age ≥65 years) who do balance activities and meet the aerobic and muscle-strengthening physical activity guidelines. The authors analyzed data on 1,012 respondents to the 2019 FallStyles survey, a nationwide web-based panel survey. Approximately four in 10 respondents (40.7%) reported doing balance activities on ≥1 day/week, 34.0% on ≥2 days/week, and 25.3% on ≥3 days/week. Prevalence differed by sex, education level, income level, census region, body mass index category, and meeting the aerobic and/or muscle-strengthening guidelines. The combined prevalence of participation in balance activities and meeting aerobic and muscle-strengthening guidelines ranged from 12.0% for ≥3 days/week to 15.8% for ≥1 day/week. Opportunities exist to introduce and increase participation in balance and multicomponent activities by older adults.

    Abstract Introduction: In 2019, the National Youth Sports Strategy was released and called for regular analysis, interpretation, and dissemination of U.S. youth sports surveillance data. The purpose of this study is to provide the recent national estimates of U.S. youth aged 6-17 years who participate in sports and examine the differences in participation by demographic characteristics, overall and across age groups.
    Methods: Nationally representative data on parent-reported youth sports participation from the 2017-2018 National Survey of Children's Health (n=36,779) were analyzed in 2019. The prevalence and 95% CIs of youth sports participation were estimated by demographic characteristics, overall and by age group. Investigators assessed the significant (p<0.05) differences and trends in participation using pairwise t-tests and orthogonal polynomial contrasts and effect modification by age group using logistic regression models.
    Results: Overall, 57.7% (95% CI=56.6, 58.9) of U.S. youth participated in sports. Participation was highest among youth who were aged 10-13 years, male, and white, non-Hispanic and increased with increasing parent/caregiver education and household income (all p<0.05). Differences in participation by demographic characteristics were more pronounced among younger youth. For example, prevalence by household income level ranged from 32.7% to 79.9% among children aged 6-9 years and from 41.6% to 67.2% among youth aged 14-17 years.
    Conclusions: Although nearly 6 in 10 U.S. youth participate in sports, substantial disparities exist, especially among younger children. Identifying and overcoming the barriers may help increase youth sports participation in the U.S.

    Abstract The present study designed a novel preoperative chemoradiotherapy (CRT) with sequential oxaliplatin and irinotecan with S-1 for locally advanced rectal cancer (LARC). This phase I study evaluated the maximum tolerated dose and recommended dose (RD) of oxaliplatin following irinotecan with S-1. Patients with clinical stage T3 or 4 or involvement of the regional nodes and no evidence of distant metastases were treated with fixed doses of S-1 (80 mg/m

    Abstract A new microbial metabolite, cytosporone S (1) was isolated from a fermentation broth of the fungus Trichoderma sp. FKI-6626. Its chemical structure was determined primarily by NMR spectroscopy and mass spectrometry. Compound 1 showed antimicrobial activity against several Gram-positive and Gram-negative bacteria and fungi.

    Abstract While most disease-modifying drugs (DMDs) regulate multiple sclerosis (MS) by suppressing inflammation, they can potentially suppress antiviral immunity, causing progressive multifocal leukoencephalopathy (PML). The DMD glatiramer acetate (GA) has been used for MS patients who are at high risk of PML. We investigated whether GA is safe for use in viral infections by using a model of MS induced by infection with Theiler’s murine encephalomyelitis virus (TMEV). Treatment of TMEV-infected mice with GA neither enhanced viral loads nor suppressed antiviral immune responses, while it resulted in an increase in the Foxp3/Il17a ratio and IL-4/IL-10 production. This is the first study to suggest that GA could be safe for MS patients with a proven viral infection.

    Abstract A 50-year-old female patient underwent distal gastrectomy and intraperitoneal CDDP administration for advanced gastric cancer accompanied by severe peritoneal dissemination. She valued her quality of life and chose an oral anticancer drug, S-1, as a postoperative chemotherapy agent. S-1 was administered at a dose of 100mg/body/day for 4 weeks, followed by a 2- week rest. There were no adverse events due to S-1 and no exacerbation of peritoneal dissemination in the 5 years following surgery. The S-1 administration schedule was then changed to alternate-day administration. Eight years after the surgery, the patient discontinued S-1 treatment and has since survived for 11 years with no obvious cancer recurrence.

    Abstract S-1 has been recommended as adjuvant chemotherapy in patients after curative surgery for gastric cancer. However, some patients suffer recurrence even after S-1 adjuvant chemotherapy. The present study was conducted to find a predictive marker of the efficacy of S-1 adjuvant chemotherapy. We examined the microRNA (miRNA) expression of 35 patients who underwent S-1 adjuvant chemotherapy after curative surgery (R0) for pathological stage II or III gastric cancer. miRNAs were extracted from formalin-fixed, paraffin-embedded specimens for analysis and miRNA expression was examined using miRNA oligo chips. Fifteen patients relapsed and 20 did not over 5 years. Five miRNAs (miR-92b, 422a, 4732-5p, 4758-3p and 221) were highly expressed according to the tumor/normal (T/N) ratio in the patients who relapsed but not in those who did not relapse (P-value <0.05) by microarray analysis. If tumors showed high expression of 4 miRNAs (miR-92b, 422a, 4732-5p and 4758-3p) their positive predictive value of relapse was 93.8% and negative predictive value was 92.3%. In this case, their disease-free survival rate and overall survival rate were very poor. Our findings indicate that miR-92b, miR‑422a, miR-4732-5p and miR-4758-3p are closely associated with relapse following S-1 adjuvant chemotherapy in gastric cancer.

    Abstract Purpose: We evaluated whether preoperative chemotherapy with S-1 and concurrent radiotherapy is feasible and efficacious in the treatment of advanced oral squamous cell carcinoma.
    Methods: Participants comprised 39 patients with oral carcinoma (stage III, n = 15; stage IVA, n = 24). All patients received a total radiation dose of 40 Gy, in once-daily 2-Gy fractions, and received S-1 at 65 mg/m(2)/day for 5 consecutive days, over 4 consecutive weeks with concurrent radiotherapy.
    Results: Hematological toxicity was mild and reversible. The most common non-hematological toxicity was grade 3 mucositis, but this was transient and tolerable. Radical surgery was performed for 37 patients, with the remaining 2 patients declining the surgery. Postoperatively, local failure developed in 1 patient, and neck failure in 2 patients. Distant metastases were identified in 4 patients. At a median follow-up of 38.0 months (range 23-88 months), locoregional control, disease-specific survival, and overall survival rates at 3 years were 91.5, 83.8, and 83.8 %, respectively.
    Conclusion: Concurrent administration of S-1 and radiotherapy combined with surgery offers a well-tolerated method of successfully treating advanced oral squamous cell carcinoma. The locoregional control rate remains high even at 3 years of follow-up, and no serious adverse effects have been encountered.

    Abstract Gramicidin S, a cationic cyclic decapeptide, exhibits the potent antibiotic activity through perturbation of lipid bilayers of the bacterial membrane. From the screening of natural antibiotics, we identified gramicidin S as a potent inhibitor for cytochrome bd-type quinol oxidase from Escherichia coli. We found that gramicidin S inhibited the oxidase with IC(50) of 3.5 microM by decreasing V(max) and the affinity for substrates but showed the stimulatory effect at low concentrations. Our findings would provide a new insight into the development of gramicidin S analogs, which do not share the target and mechanism with conventional antibiotics.
