Abstract
Providing standardized, high-quality rehabilitation for critically ill patients is a crucial issue. In 2017, the Japanese Society of Intensive Care Medicine (JSICM) promulgated the "Evidence-Based Expert Consensus for Early Rehabilitation in the Intensive Care Unit" to advocate for the early initiation of rehabilitations in Japanese intensive care settings. Building upon this seminal work, JSICM has recently conducted a rigorous systematic review utilizing the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) methodology. This endeavor resulted in the formulation of Clinical Practice Guidelines (CPGs), designed to elucidate best practices in early ICU rehabilitation. The primary objective of this guideline is to augment clinical understanding and thereby facilitate evidence-based decision-making, ultimately contributing to the enhancement of patient outcomes in critical care settings. No previous CPGs in the world has focused specifically on rehabilitation of critically ill patients, using the GRADE approach. Multidisciplinary collaboration is extremely important in rehabilitation. Thus, the CPGs were developed by 73 members of a Guideline Development Group consisting of a working group, a systematic review group, and an academic guideline promotion group, with the Committee for the Clinical Practice Guidelines of Early Mobilization and Rehabilitation in Intensive Care of the JSICM at its core. Many members contributed to the development of the guideline, including physicians and healthcare professionals with multiple and diverse specialties, as well as a person who had been patients in ICU. Based on discussions among the group members, eight important clinical areas of focus for this CPG were identified. Fourteen important clinical questions (CQs) were then developed for each area. The public was invited to comment twice, and the answers to the CQs were presented in the form of 10 GRADE recommendations and commentary on the four background questions. In addition, information for each CQ has been created as a visual clinical flow to ensure that the positioning of each CQ can be easily understood. We hope that the CPGs will be a useful tool in the rehabilitation of critically ill patients for multiple professions.

Abstract
A variety of substrates and substances were coated with conductive polymers at low temperature under ambient pressure. The substrate coating with heteroaromatic polymers proceeded through spontaneous oxidation and polymerization of the monomers, such as pyrrole (Py) and thiophene (Tp) derivatives. The monomer liquid, the solid nitrate oxidant, and the substrate were put in a closed vessel. The vapor of the activated monomer was spontaneously generated on the surface of the solid nitrate oxidant through the diffusion of the monomer vapor. The monomer and its activated species were adsorbed and polymerized on the surface of any substrate in the reaction vessel. The thickness was controlled by the reaction time. The substituents of the monomers had an influence on the coating rate. The morphology of the coated polymers was changed by the substrates with different wettabilities. The thin coating of the heteroaromatic polymer was applied to the preparation of an electrode for charge storage based on the redox reaction. The thin coating on the current collector showed an enhanced high-rate charge-discharge performance. The present synthetic approach can be applied to the coating of polymer materials on a variety of substrates from the monomer vapor under mild conditions.

Abstract
OBJECTIVE A higher trans-epidermal water loss (TEWL) occurs in rough skin, in elder skin and also in atopic dermatitis. An impaired skin barrier function is considered to be caused by an incomplete construction of the intercellular lamellar structure due to the quantitative reduction of ceramides. Since these symptoms coexist with oxidative stress, we hypothesized that impairment of the skin barrier function is accelerated by oxidative stress. Thus, the purpose of this study was to clarify the effect of oxidative stress on ceramide synthesis and to characterize whether antioxidants can improve skin barrier function. 3-O-Laurylglyceryl ascorbate (VC-3LG), which is a newly amphipathic derivative of ascorbic acid, was evaluated as a candidate antioxidant. METHODS We characterized the mRNA expression levels of serine palmitoyltransferase (SPT) in normal human epidermal keratinocytes (NHEKs) treated with H2 O2 using real-time PCR analysis. In order to evaluate the effect of VC-3LG on skin barrier function, we used several assays with reconstructed human epidermis equivalents (RHEEs). RESULTS Ceramide synthesis was down-regulated in NHEKs by oxidative stress. Treatment with VC-3LG abrogated the down-regulation of SPT mRNA in NHEKs caused by oxidative stress, and stimulated SPT mRNA expression levels. In experiments characterizing the antioxidative properties of VC-3LG, VC-3LG reduced oxidative stress in NHEKs by up-regulating catalase mRNA expression. In addition, VC-3LG stimulated the skin barrier function in RHEEs, which had lower TEWL values compared with untreated RHEEs. Furthermore, VC-3LG increased the quantity of ceramide in RHEEs. CONCLUSION Taken together, we conclude that VC-3LG reinforces the skin barrier function due to its reduction of oxidative stress and its promotion of ceramide synthesis.

Abstract
BACKGROUND Many researchers have studied differences in conditions of ethnic skin using biophysical measurements. However, few studies to date have focused on the antioxidative capacity of the skin. METHODS We measured two parameters of oxidative stress in the stratum corneum, catalase activity and protein carbonylation of the stratum corneum (SCCP), in two ethnic groups, Japanese and French subjects, to characterize the susceptibility to oxidative stress. We also measured several physiological parameters at three different skin sites, two sun-exposed sites (cheek and dorsal aspect of the hand) and a sun-protected site (inner upper arm), in both ethnic groups. RESULTS Transepidermal water loss (TEWL), the size of corneocytes and skin color showed differences between sun-exposed and sun-protected sites regardless of ethnicity. Regarding ethnic differences, catalase activities and parameters of skin hydration and barrier function of Japanese subjects were higher than those of French subjects. However, SCCP values showed a trend contrary to catalase activity. The difference in the b* value indicated that the melanin content of Japanese skin was higher than that of French skin. Pearson's correlation analyses showed that catalase activity and SCCP values had weak relationships with water content, TEWL and skin color in both ethnic groups. CONCLUSION Differences in susceptibility to oxidative stress, namely melanin content and catalase activity in the skin, induce the better skin condition of Japanese compared with French subjects.

Abstract
In recent years, bottled mineral water has undergone inactivation by methods other than the traditional heat treatment during the production process; there are fewer reports of the effectiveness of these inactivation methods on yeasts and molds in mineral water than on bacteria and protozoan oocysts. In this study, we evaluated the effects of UV irradiation and ozone treatment compared with heat treatment at 85 degrees C on yeast cells and mold spores inoculated into mineral water. A 5-log reduction occurred at a UV radiation dose of 31,433 microJ/cm2 for Saccharomyces cerevisiae and at 588,285 microJ/cm2 for Penicillium pinophilum. The treatment time for 5-log reduction estimated for UV irradiation was about 0.6 min for S. cerevisiae and about 10.7 min for P. pinophilum; at an ozone concentration of 0.1 ppm, it was 1.75 min for S. cerevisiae and 2.70 min for P. pinophilum, and at a concentration of 0.6 ppm, it was 0.32 min for S. cerevisiae and 0.57 min for P. pinophilum. Comparison of the inactivation effects among the three methods showed that UV irradiation and ozone treatment were less effective than heat treatment at 85 degrees C. Thus, when UV irradiation and ozone treatment are used for inactivation of mineral water, it seems that they need to be combined with heat treatment to achieve a definite effect. Yeast cells are more sensitive to all three inactivation methods than are mold spores, and the sensitivity of yeast cells and mold spores to these inactivation methods may vary among genera.

Abstract
The purpose of this study was to clarify the incidence and characteristics of late-onset complications of the spine in children who underwent intra-operative radiation therapy (IORT) for common paediatric malignant tumours. 12 children with more than 4 years of follow-up after IORT were included and, in 11 of these, thoracic and/or lumbar spines were irradiated. To compare doses of irradiation to the spine with the resulting deformities, dose simulations of IORT were carried out on two selected cases using a radiation treatment planning system with a pencil-beam algorithm. The mean follow-up period was 135 months (range, 53-234 months). Radiographic reviews found spinal deformity in six patients. Only one patient was symptomatic and the spinal deformity was severe (Grade 3), whereas spinal deformity was mild in the remaining five patients without clinical symptoms (Grade 1). In all of the six patients, anterior wedge-shaped deformity was dominant, and scoliosis was found in only two patients. In one particular case with nephrectomy, irradiation had penetrated much deeper than usual at the site of nephrectomy, and dose distribution was asymmetric, causing clinically significant spinal deformity with scoliosis. In conclusion, specific deformities of the spine observed after IORT can be explained on the basis of dose distribution of the electron beam to the spine.

Abstract
OBJECTIVE To further analyse the significance and mutual relationship of thyroid function-linked alterations in cortisol metabolism that have been separately and variously reported. PATIENTS AND MEASUREMENTS Twenty-four-hour urine samples from 21 patients with hyperthyroidism (Graves' disease), 16 patients with hypothyroidism (Hashimoto's thyroiditis), 21 healthy age- and sex-matched controls for hyperthyroidism, and 16 healthy age- and sex-matched controls for hypothyroidism were evaluated for 6beta-hydroxycortisol (6beta-OHF), tetrahydrocortisol (THF), tetrahydrocortisone (THE), allo-tetrahydrocortisol (allo-THF), urinary free cortisol (UFF), urinary free cortisone (UFE) and 17-hydroxycorticosteroid (17-OHCS). RESULTS Urinary 17-OHCS, THE and allo-THF levels increased considerably in hyperthyroid patients compared to the controls, while UFF and THF showed no difference between the two groups. Urinary 6beta-OHF was significantly lower in the hyperthyroid patients than in the controls. Both the urinary allo-THF + THF/THE and the UFF/UFE ratios were significantly lower in the hyperthyroid patients than in the controls, whereas only the former was significantly higher in the hypothyroid patients than in the controls. The urinary allo-THF/THF ratio was significantly higher in the hyperthyroid patients and significantly lower in the hypothyroid patients than in the controls. In an analysis of pooled subjects including all groups (n = 64), free T4 levels correlated negatively (P < 0.0001) with the urinary allo-THF + THF/THE ratio but not with the UFF/UFE ratio. The serum levels of free T4 correlated positively (P < 0.0001) with the urinary allo-THF/THF ratio. CONCLUSION The thyroid hormones seem to affect the total 11beta-HSD activity (allo-THF + THF/THE) more strongly than the renal 11beta-HSD2 activity (UFF/UFE). 5alpha-reductase activity (allo-THF/THF) is also enhanced in hyperthyroidism, while the reduction of urinary 6beta-OHF in hyperthyroidism might be a secondary effect of the altered activity of the total 11beta-HSD and 5alpha-reductase.

Abstract
We describe the case of a 51-year-old man with hepatitis C virus (HCV) infection and a 3-month history of facial edema. Laboratory tests upon admission for renal biopsy showed normal renal function and normocomplementemia. Serum HCV antibody (Ab) and cryoglobulin were positive. Renal biopsy specimens showed features of membranous glomerulonephritis. The likely cause was immune complex-mediated glomerulonephritis associated with HCV infection. Reports of similar cases in the literature show the normocomplementemia and negative or slightly positive cryoglobulins observed in our case as well as seropositivity for circulating immune complexes containing HCV RNA. In our case, electron microscopic examination of the subepithelial glomerular lesions revealed massive virus-like particles within unusual multilayers of electron-dense deposits (EDDs), suggesting the existence of HCV in the glomeruli. In the addition to the unique histopathological feature the presence of La/SS-B antibody in his serum indicated an abnormal immune response associated with HCV. We advise him to undergo the therapy with new type of IFN such as pegIFN-alpha2a and/or anti-viral agent like ribavirin to achieve clinical and histopathological improvement.

Abstract
Five cases of surgically treated thymic carcinoma are reported. The patients (4 men and a woman) ranged in age from 46 to 76 years old with a mean of 64.6. Four patients were asymptomatic and an abnormal shadow on X-ray films was noted. One remaining patient suffered from hoarseness. One patient had stage II disease and the others had stage III. Surgical tumor resection was performed in all cases. Only 1 patient among the 5 underwent a successful complete resection. Histological examinations of the resected specimens revealed squamous cell carcinoma of thymus. Four specimens were poorly differentiated and 1 is moderately differentiated carcinoma. All patients received radiation therapy post operatively. Three patients are alive without any recurrence 6, 8 and 109 months after the surgery. Thymic carcinomas are frequently invasive or metastatic at the time of diagnosis. But poorly differentiated group, in squamous cell carcinoma, mucoepidermoid carcinoma and besaloid carcinoma, are characterized by a low incidence of local recurrence and distant metastasis. They also have a good sensitivity for the radiation. Therefore complete surgical resection combined with postoperative radiation therapy should be a choice in treating thymic carcinomas. We considered that complete resection and postoperative radiation therapy is a curative therapy for thymic carcinomas.
