Exploratory study on quantitative assessment of skin hardness in patients with systemic sclerosis using SOFTGRAM
滋賀医科大学博士(医学)OBJECTIVES:
There is a lack of quantitative and objective methods for measuring skin hardness. This study aimed to verify whether SOFTGRAM, a device that can measure elastic modulus using the Hertz elastic contact theory, could be used to evaluate skin hardness in systemic sclerosis (SSc).
METHODS:
Skin score according to the modified Rodnan total skin thickness score and elastic modulus of the skin using SOFTGRAM were measured for 20 patients with SSc and 20 healthy controls on 8 parts of the body, both of the cheeks, forearms, fingers, and hands. Five observers shared to measure skin score 320 times (40 participants × 8 parts). Elastic modulus was measured 1600 times (40 participants × 8 parts × 5 times each). As an additional examination to compare differences between observers, the skin score of another healthy control was measured 40 times (5 observers × 8 parts). Elastic modulus was measured 200 times (5 observers × 8 parts × 5 times each).
RESULTS:
There was a significant correlation between elastic modulus and skin score (correlation coefficient=0.67, p<0.001) and a significant difference in elastic modulus (8 parts: healthy controls vs. limited cutaneous SSc vs. diffuse cutaneous SSc: 22.6±15.7 vs. 32.0±27.7 vs. 44.8±39.8, p<0.001). Intraobserver reliabilities were sufficient in 6 out of 7 observers; however, interobserver was less satisfactory.
CONCLUSIONS:
This study showed the practicality of SOFTGRAM as an accurate measurement method of skin hardness but also revealed points to be improved. More studies are needed to find an accurate measurement method of skin hardness.令和6年度doctoral thesi

日本の小児医療において,成人期を迎えた小児期発症の慢性疾患患者の成人診療科への移行期医療と成人移行支援が課題となっている.2017(平成29)年の厚生労働省からの要請により,全国で小児慢性特定疾病の患者に対する移行期医療支援体制の構築が進められている.滋賀県では2024(令和6)年4月に「移行期医療支援センター」を滋賀医科大学医学部附属病院に全国で11番目に設置した.本稿では,その準備にあたった「移行期医療連携チーム」の2022-2023(令和4-5)年度の2年間の活動を報告する.先行して取り組む自治体の方法を参考に,病院内の支援体制を整えるためロードマップを作成し,まずは多職種で構成するチームを形成した.メンバーは,小児科外来を担当する医師,成人診療科の外来を担当する医師,小児病棟や小児科外来の看護師,患者支援センター看護師,医療ソーシャルワーカーなどの専門職である.患者が小児科から成人科へ移行することと同時に,患児が自律および自立した成人患者へと成長する過程を辿れるような援助を目指した.小児科と成人診療科をつなぎ移行患者の情報を把握し集約する役割は,移行期支援外来として小児科外来看護師が担うことになった.「移行期医療連携フロー」図に沿って関連部署間で協働できる体制を組み立て,患者と家族に周知できるようポスターを病院内に掲示した.多職種間で情報を共有するための移行期医療連携チーム介入依頼シートやチェックリストなど書類を作成した.さらに,本課題が病院内の医療者やコメディカルスタッフと共有できるようセミナーを開催した.特に困難であったのは,専門職種間の連携のあり方や患者の特徴や背景に合わせた対応であった.日常業務に加え新たな活動を行うマンパワーの負担や移行期支援に対する診療加算がないことは,活動推進に影響したと思われる.今後も引き続き課題として取り組んでいきたい.departmental bulletin pape

Metabolic Analysis of Three-Dimensional Cultured Gastrointestinal Cancer Cells Suggests that l-Arginine Inhibits Tumor Growth by Affecting the Urea Cycle
滋賀医科大学博士(医学)Introduction: There is evidence for the anticancer effects of l-arginine (arginine); however, the direct effects on cancer cells and mechanism of action are unclear. Methods: Various upper gastrointestinal cancer cells (OE19, OE33, MKN1, MKN45, MKN74, and AGS) were divided into arginine-treated and -untreated groups and cultured using two-dimensional and three-dimensional culture systems. Proliferation was evaluated using the MTT assay to identify arginine-sensitive (OE33) and arginine-insensitive (OE19) strains. Furthermore, the effects of arginine were evaluated using a mitochondrial stress test, cell cycle assay, comprehensive metabolic analysis, and tracer study using (13C6) l-arginine. Results: In OE33 (but not in OE19), the maximal respiratory capacity of mitochondria was lower in the treated group than in the control group. In OE33, S phase cells (determined using BrdU) were significantly reduced. In a comprehensive metabolic analysis of OE33, citrulline/ornithine levels were significantly lower in arginine-treated than in untreated cells. Using OE33, carbamoyl aspartic acid (CAA) levels were significantly lower in arginine-treated than in untreated cells. A tracer study suggested that arginine promotes the urea cycle. Conclusion: Arginine affected urea cycle metabolism, thereby decreasing CAA, which is required for pyrimidine nucleotide synthesis. These findings provide insight into the mechanism underlying the anticancer effects of arginine.令和6年度doctoral thesi
