Maintaining employees’ presenteeism is a major issue in the workplace. Simple and convenient methods to improve presenteeism are required. We investigated whether administering the lactic acid bacteria Lactococcus lactis strain Plasma (LC-Plasma) can improve the performance and physical condition of office workers. Subjects were randomly assigned to one of two groups: 1) an intake period (consumption of LC-Plasma-containing yogurt beverage) followed by a non-intake period, or 2) a non-intake period followed by an intake period. Each period lasted 4 weeks and there was a 4-week washout period between each. Assessment was conducted using the World Health Organization Health and Work Performance Questionnaire (HPQ), the Profile of Mood States (POMS) questionnaire and physical condition questionnaires. A total of 153 subjects were analyzed. Absolute presenteeism (as assessed by the HPQ) and vigor (as assessed by POMS) were significantly higher in the intake period than the non-intake period. The subject’s physical health (as assessed by typical common cold symptoms, physical condition, sneezing or runny noses, coughing or sore throats, and lassitude) was also superior during the LC-Plasma intake period. Our results suggest that intake of LC-Plasma for 4 weeks improves work performance through reducing the risk of infection.

In this study, I suggest a new vegetation index to express 3 dimensional structure of vegetation. I measured BRF every real vegetation type with the observation system which utilized a RC helicopter. I made clear a difference of BRF every vegetation type from this measurement result and suggested a new vegetation index (BSI). As a result, the suggestion index was able to show a difference of shape of canopy in vegetation type of the same vegetation cover rate.

Background/Aims: The presence of invasion is a diagnostic criterion of early gastric cancer (EGC) in Korea, whereas diagnosis in Japan is based on enlarged nuclei and prominent nucleoli. Moreover, the depth of invasion is the location of cancer cell infiltration in Korea, whereas it is the location of lymphovascular invasion (LVI) or cancer cell infiltration in Japan. We evaluated the characteristics of EGC with LVI to uncover the effects of different diagnostic criteria. Methods: Consecutive T1-stage EGC patients who underwent complete resection were included after endoscopic or surgical resection. The presence of LVI was evaluated. Results: LVI was present in 112 of 1,089 T1-stage EGC patients. LVI was associated with depth of invasion (p<0.001) and age (p=0.017). The prevalence of LVI in mucosal cancer was significantly higher in Korea (p<0.001), whereas that of submucosal cancer was higher in Japan (p=0.024). For mucosal EGC types, LVI was positively correlated with diagnostic criteria applied in Korea (p=0.017). For submucosal EGC types, LVI was positively correlated with Japanese criteria (p=0.001) and old age (p=0.045). Conclusions: The higher prevalence of LVI for mucosal EGC in Korea and for submucosal EGC in Japan indicates that different diagnostic criteria should be considered when reading publications from other countries.

[Purpose] Exercise is a key factor in preventing obesity and metabolic syndrome. Sumo wrestlers increase their body size from childhood for athletic advantage; however, the risk of metabolic syndrome in junior sumo wrestlers is undetermined. Preventive measures against pediatric obesity should be initiated during childhood to prevent obesity in adulthood, considering its high global incidence. We comparatively evaluated the risk factors for metabolic syndrome in junior sumo wrestlers and children with obesity. [Methods] We enrolled 70 male children (age 9-17 years [sumo group, n = 14] and 9-14 years [other sports and non-exercise groups, n = 28 each]) and evaluated their anthropometric parameters (height, weight, body mass index z-score, obesity rate, waist circumference, waist to height ratio) and hematological parameters (total, low-density, high-density, and non-high-density lipoprotein-cholesterol; triglycerides; plasma glucose, and glycated hemoglobin levels). [Results] The BMI z-score, obesity rate, waist circumference (p < 0.05, along with the non-exercise group), and systolic blood pressure were significantly higher and the high-density cholesterol level was lower in the sumo group than in the other sports group (p < 0.05). The waist to height ratio was significantly higher in the non-exercise group than in the other sports group (p < 0.05). No significant difference was found in other blood lipid, plasma glucose (significantly lower level than the reference range in the sumo group, p < 0.05), and glycated hemoglobin (within the reference range in all groups) levels among the three groups. [Conclusion] Junior sumo wrestlers had a larger body size and higher blood pressure than children with obesity who exercised regularly. This provides direction for future research into targeted preventive interventions against metabolic syndrome for junior sumo wrestlers with large body size.

Behçet’s disease (BD) is a multisystem inflammatory disease of unknown origin. Rarely, BD occurs together with myelodysplastic syndrome (MDS). Interestingly, it is speculated that these are not simple coexistence but that the etiology of intestinal BD is at least partly derived from MDS itself. Furthermore, there is a relationship between MDS in patients with intestinal BD and trisomy 8. Immunosuppressive agents alone are insufficient to control MDS-associated BD, and many of these patients die of infection or hemorrhage. Surgery is considered for intestinal BD patients who are unresponsive to medical treatment or those with bowel complications such as perforation or persistent bleeding. We report a case of intestinal BD associated with MDS and trisomy 8. The patient was unresponsive to oral steroids and immunosuppressive treatment; the patient improved by surgical repair of a bowel perforation. Five years after the surgery, the patient is free of recurrence and not on medication. Our experience suggests that surgery may provide an effective therapeutic option for the treatment of MDS-related BD. (Intest Res 2020;18:469-475)
