We conducted an overseas mobile clinic in Lao PDR and examined the results of biochemical tests and blood examinations. For the biochemical tests, we used a method involving plasma skimming film and filter paper, called “plasma separation plate.” In this study, we report the usefulness of the plasma separation plate, which is a newly developed method for the screening of biochemical tests in Japan. We were able to apply this method in a mobile clinic in Lao PDR. The quantitative concentration of plasma from blood collected from pricked fingers was measured by this method. Using the plasma skimming film and filter paper, the non-cell components in the blood were separated, and a quantity of the plasma was adsorbed by filter paper. Neither elaborate equipment nor electricity was required. The results of our test data indicated that few inhabitants suffered from adult diseases for which we were screening. We concluded, therefore, that this method is suitable for use in mobile clinics in the rural areas of developing countries.

To evaluate the association of serum BDNF concentration with high-intensity interval training, 12 healthy male volunteers, aged 28-48 years, completed 16-week high-intensity interval training (HIIT) using ergometer. Training program consisted of >90% VO2 peak for 60 sec separated by 60 sec active rest period for 8-12 sets twice weekly for 16-week. Maximal exercise tolerance tests were performed before (0-week), 4-week, and 16-week after the intervention program. VO2 peak as well as peak watt was linearly increased after 4-week (9% for both VO2 peak and peak watt) and 16-week HIIT training (15% for VO2 peak and 18% for peak watt, p<0.01). However, there was no change in serum BDNF concentration by HIIT. On the other hand, there was a positive association of serum BDNF concentration at baseline with % increase in peak watt after the intervention (ρ=0.60, p<0.05). The association between BDNF and exercise training is still unclear, and more studies are needed to clarify the above positive association.

Recently, the problem of the high incidence of throwing injuries in young people has been gaining attention. Identifying high-risk players before the onset of the throwing injury is important for prevention. One of the most widely used screening tests for sports-related injuries is the Functional Movement Screen (FMS), which assesses the quality of movement; however, its correlation with throwing injuries has not been established. The purpose of this study was to investigate the correlation between the FMS score and throwing injuries. The FMS was used during the medical check for two hundred and thirty junior high school baseball players. We allotted those who had experienced throwing injuries multiple times to the injury group and those who had never experienced throwing injury to the control group. We then calculated the FMS cutoff value using the receiver operating characteristic curve. In addition, we investigated differences in the incidence of throwing injury between above and below the cutoff value using chi-square test. The FMS cutoff score was 17. Players who scored ≤17 had a significantly higher incidence of throwing injuries than those who scored ≥18. Conclusion: We believe that FMS score is correlated to throwing injuries. In addition, the results suggest that throwing injuries might be prevented in junior high school baseball players who scored ≤17 on the FMS if they undergo training in the correct movement patterns.

Computed tomography (CT) is widely used in postmortem investigations as an adjunct to the traditional autopsy in forensic medicine. To date, several studies have described postmortem CT findings as being caused by normal postmortem changes. However, on interpretation, postmortem CT findings that are seemingly due to normal postmortem changes initially, may not have been mere postmortem artifacts. In this pictorial essay, we describe the common postmortem CT findings in cases of atraumatic in-hospital death and describe the diagnostic pitfalls of normal postmortem changes that can mimic real pathologic lesions.

To date, there has been no comprehensive study on the relationship of stress response, coping and lifestyle (e.g., diet, exercise habits, and sleeping habits) with premenstrual syndrome (PMS) for female athletes. This study aimed to examine this relationship. We used a web questionnaire to acquire the required data from Japanese female university athletes. Based on structural equation modeling, we used the PMS score as an outcome and examined its relationship to stress response, emotion-focused coping, dietary intake, amount of exercise in club activities surveyed by club unit, and sleeping time. Our study included 257 subjects (average age, 20 years). The results showed that the stress response was a direct factor in the PMS score (standardized coefficient: .63). Emotion-focused coping and dietary intake were associated with PMS scores through stress response (-.26 and -.27, respectively). Emotion-focused coping was also associated with the dietary intake (.19). Factors associated with emotion-focused coping were amount of exercise (.22) and sleeping time (.27). The amount of exercise was associated with sleeping time (-.26). These results suggest that avoiding stressors, enhancing emotion-focused coping, reducing the stress response by maintaining a balanced and sufficient diet, performing an appropriate amount of exercise, and improving sleep habits may be effective in managing PMS.

Purpose:
To investigate the association between skin advanced glycation end-products (AGEs) levels, blood antioxidative vitamin and carotenoid concentrations, and severe erectile dysfunction (ED) in community-dwelling men.
Materials and Methods:
This cross-sectional study used the 5-Item International Index of Erectile Function to identify 335 community-dwelling men with ED. The accumulation of skin AGEs was assessed noninvasively by measuring skin autofluorescence. Background-adjusted multivariable logistic regression analyses using the inverse probability of treatment weighting method were performed to evaluate the effects of AGEs, vitamins, and carotenoids on severe ED. Moreover, multiple linear regression analyses were performed to assess the association between skin AGEs levels and serum carotenoid concentrations.
Results:
The median age of study participants was 57 years. Of the 335 men, 289 (86.3%) and 46 (13.7%) were classified into the mild/moderate and severe ED groups, respectively. Multivariable analyses revealed that skin AGEs levels, blood vitamins C and E, lutein, zeaxanthin, β-cryptoxanthin, α-carotene, β-carotene, total lycopene, and cis-lycopenes concentrations were significantly associated with severe ED, whereas all-trans lycopene concentrations were not. In the multiple linear regression analyses, serum zeaxanthin concentrations were negatively and significantly correlated with skin AGEs levels.
Conclusions
Higher skin AGEs levels and lower blood antioxidative vitamin and carotenoid concentrations were significantly associated with severe ED. Serum zeaxanthin levels were negatively and significantly correlated with skin AGEs levels, suggesting the possible effects of zeaxanthin on ED by decreasing tissue AGEs levels.
