    Abstract This study aimed to investigate the toxic and transcriptomic effects of the ultraviolet filter benzophenone-3 (BP-3) on Acropora tenuis and its symbiotic dinoflagellates while using acetone as a solvent. Seven-day exposure to 50 and 500 μg/L, which is higher than most BP-3 records from coastal waters, did not affect coral colour or dinoflagellate photosynthesis. Differentially expressed genes (DEGs) between seawater and solvent controls were <20 in both corals and dinoflagellates. Eleven coral DEGs were detected after treatment with 50 μg/L BP-3. Fourteen coral DEGs, including several fluorescent protein genes, were detected after treatment with 500 μg/L BP-3. In contrast, no dinoflagellate DEGs were detected in the BP-3 treatment group. These results suggest that the effects of 50-500 μg/L BP-3 on adult A. tenuis and its dinoflagellates are limited. Our experimental methods with lower acetone toxicity provide a basis for establishing standard ecotoxicity tests for corals.

    Abstract Genetic diversity of plant populations on islands is likely to be influenced by characteristics such as island origin (oceanic or continental) and their age, size, and distance to continental landmasses. In Japan, Planchonella obovata sensu lato which is found on both continental and oceanic islands of varying age, size, and distance to East Asian continental areas-is an ideal system in which to investigate the factors influencing genetic diversity of island plant species. In this study, we examined the genetic diversity of P. obovata s.l. populations, in the context of the species population genetic structure, demography, and between island migration, from 668 individuals, 28 populations and 14 islands including both continental (the Yaeyama Islands) and oceanic islands (the Daito, Bonin, and Volcano Islands) using 11 microsatellite markers. The Yaeyama and Volcano Islands respectively had the highest and lowest genetic diversity, and island origin and age significantly affected genetic diversity. Clustering analysis revealed that populations were grouped into Bonin, Volcano, and Yaeyama + Daito groups. However, Bonin and Volcano groups were distinct despite the relatively short geographical distance between them. Approximate Bayesian Computation analysis suggested that the population size was stable in Bonin and Yaeyama + Daito groups, whereas population reduction occurred in Volcano group, and migration between groups were very limited. Younger oceanic islands showed lower genetic diversity, probably due to limited gene flow and a lack of time to accumulate unique alleles. Genetic structure was generally consistent with the geographic pattern of the islands, but in Volcano, a limited number of founders and limited gene flow among islands are likely to have caused the large genetic divergence observed.

    Abstract There is scarce evidence regarding the risk of weight loss and the effect of having registered dietitians (RDs) on staff in rehabilitation wards on weight loss. We aimed to examine the effects of RDs in Kaifukuki (convalescent) rehabilitation wards (KRWs) on the prevention of weight loss in adult patients. Data from 2-year nationwide annual surveys on KRWs in Japan were retrospectively analysed. Weight loss was defined as loss of ≥5% weight during the KRW stay. Risk of weight loss in class 1 KRWs (obligated to provide nutrition care) was compared with that in class 2-6 KRWs (not obligated). Risk of weight loss in class 2-6 KRWs with RDs was compared to those without. Overall, 17.7% of 39,417 patients lost weight. Class 1 KRWs showed a lower risk of weight loss than class 2-6 KRWs (17.3% vs. 18.5%,

    Abstract Purpose: Our objective was to report the outcome and prognostic factors for patients with locally recurrent rectal cancer (LRRC) treated with proton beam therapy (PBT) at our institution.
    Methods and materials: The study included PBT-treated patients with LRRC between December 2008 and December 2019. Treatment response was stratified using an initial imaging test after PBT. Overall survival (OS), progression-free survival (PFS), and local control (LC) were estimated using the Kaplan-Meier method. Each outcome's prognostic factors were verified using the Cox proportional hazards model.
    Results: Twenty-three patients were enrolled (median follow-up, 37.4 months). There were 11 patients with complete response (CR) or complete metabolic response (CMR), 8 with partial response or partial metabolic response, 2 with stable disease or stable metabolic response, and 2 with progressive disease or progressive metabolic disease. Three- and 5-year OS, PFS, and LC were 72.1% and 44.6%, 37.9% and 37.9%, and 55.0% and 47.2%, respectively, with 54.4 months' median survival time. The maximum standardized uptake value of fluorine-18-fluorodeoxyglucose-positron emission tomography-computed tomography (
    Conclusions: The results showed that PBT may have potential to be a good treatment option for LRRC.

    Abstract Although the role of aerobic glycolysis in activated T cells has been well characterized, whether and how fatty acids (FAs) contribute to donor T cell function in allogeneic hematopoietic stem cell transplantation is unclear. Using xenogeneic graft-versus-host disease (GVHD) models, this study demonstrated that exogenous FAs serve as a crucial source of mitochondrial respiration in donor T cells in humans. By comparing human T cells isolated from wild-type NOD/Shi-scid-IL2rγnull (NOG) mice with those from MHC class I/II-deficient NOG mice, we found that donor T cells increased extracellular FA uptake, the extent of which correlates with their proliferation, and continued to increase FA uptake during effector differentiation. Gene expression analysis showed the upregulation of a wide range of lipid metabolism-related genes, including lipid hydrolysis, mitochondrial FA transport, and FA oxidation. Extracellular flux analysis demonstrated that mitochondrial FA transport was required to fully achieve the mitochondrial maximal respiration rate and spare respiratory capacity, whereas the substantial disruption of glucose supply by either glucose deprivation or mitochondrial pyruvate transport blockade did not impair oxidative phosphorylation. Taken together, FA-driven mitochondrial respiration is a hallmark that differentiates TCR-dependent T cell activation from TCR-independent immune response after hematopoietic stem cell transplant.

    Abstract The aim of the present study was to report the feasibility of proton beam reirradiation for patients with locally recurrent rectal cancer (LRRC) with prior pelvic irradiation. The study population included patients who were treated with proton beam therapy (PBT) for LRRC between 2008 and December 2019 in our institution. Those who had a history of distant metastases of LRRC, with or without treatment, before reirradiation, were excluded. Overall survival (OS), progression-free survival (PFS) and local control (LC) were estimated using the Kaplan-Meier method. Ten patients were included in the present study. The median follow-up period was 28.7 months, and the median total dose of prior radiotherapy (RT) was 50 Gy (range, 30 Gy-74.8 Gy). The median time from prior RT to reirradiation was 31.5 months (range, 8.1-96.6 months), and the median reirradiation dose was 72 Gy (relative biological effectiveness) (range, 56-77 Gy). The 1-year/2-year OS, PFS and LC rates were 100%/60.0%, 20.0%/10.0% and 70.0%/58.3%, respectively, with a median survival time of 26.0 months. Seven patients developed a Grade 1 acute radiation dermatitis, and no Grade ≥ 2 acute toxicity was recorded. Grade ≥ 3 late toxicity was recorded in only one patient, who had developed a colostomy due to radiation-related intestinal bleeding. Reirradiation using PBT for LRRC patients who had previously undergone pelvic irradiation was feasible. However, the indications for PBT reirradiation for LRRC patients need to be considered carefully due to the risk of severe late GI toxicity.

    Abstract Background and objectives: Barley mixed rice, "Mugi gohan," is traditionally eaten with yam paste in Japan. Both ingredients contain dietary fiber and reportedly reduce postprandial hyperglycemia. However, evidence supporting the benefits of combining barley mixed rice with yam paste is limited. In this study, we evaluated whether ingesting a combination of barley mixed rice and yam paste affected postprandial blood glucose concentration and insulin secretion.
    Methods and study design: This study followed an open-label, randomized controlled crossover design, following the unified protocol of the Japanese Association for the Study of Glycemic Index. Fourteen healthy subjects each consumed four different test meals: white rice only, white rice with yam paste, barley mixed rice, and barley mixed rice with yam paste. We measured their postprandial blood glucose and insulin concentrations after every meal, and we calculated the area under curve for glucose and insulin.
    Results: Participants had significantly reduced area under curve for glucose and insulin after eating barley mixed rice with yam paste compared to when they ate white rice only. Participants had similar area under curve for glucose and insulin after eating barley mixed rice only, or eating white rice with yam paste. Participants had lower blood glucose concentrations 15 min after eating barley mixed rice only, whilst eating white rice with yam paste did not maintain lower blood glucose after 15 min.
    Conclusions: Eating barley mixed rice with yam paste decreases postprandial blood glucose concentrations and reduces insulin secretion.

    Abstract Background: In advanced non-small cell lung cancer (NSCLC) patients harboring epidermal growth factor receptor (EGFR) mutations, those with impaired performance status (PS) treated with EGFR-tyrosine kinase inhibitors (TKIs) have demonstrated comparable activities to good-PS patients. Due to the limited sample size and inclusion of older adult patients with good PS, these findings may not accurately depict the efficacy of EGFR-TKI in poor-PS patients. We investigated the benefit of EGFR-TKIs in this population and identified relevant prognostic factors.
    Patients and methods: This nationwide prospective registry study included 9872 patients with local or advanced NSCLC. Outcomes were compared between poor- and good-PS patients treated with EGFR-mutated lung cancer therapies.
    Results: Of 9872 NSCLC patients, 1965 (19.9%) had EGFR mutations, with 1846 (93.9%) presenting common EGFR mutations. Poor PS (PS score ≥ 3) was noted in 171 patients (8.7%) and identified as an independent prognostic factor; those with poor PS had a significantly lower 1-year survival rate. The median overall survival (OS) for EGFR-TKI-treated good-PS patients was 31.5 (95% confidence interval, 29.6-33.4) months. Among poor-PS patients with EGFR mutations, 135 (78.9%) of whom were treated with EGFR-TKI had an OS of 15.5 (12.7-18.3) months, while those receiving only supportive care had an OS of 2.5 (1.4-3.6) months (P < .001). Hypoalbuminemia (< 3.5 g/dL), liver metastasis, and uncommon EGFR mutations were associated with poor prognosis.
    Conclusion: Poor PS at diagnosis was rare and associated with limited EGFR-TKI efficacy and a dismal prognosis. Liver metastasis and hypoalbuminemia may reduce EGFR-TKI efficacy in these patients.
