Intra- and extra-familial adverse childhood experiences and a history of childhood psychosomatic disorders among Japanese university students

BACKGROUND: Japan has been witnessing a considerable increase in the number of children with psychosomatic disorders. The purpose of this study is to examine the relationship between the risk of psychosomatic disorder in adolescents and intra- and extra-familial adverse childhood experiences (ACEs). METHODS: A retrospective cohort study of 1592 Japanese university students (52% male, mean age 19.9 years) who completed a survey about intra- and extra-familial ACEs and the incidence of childhood psychosomatic disorders. Intra-familial ACEs included domestic violence, physical violence, emotional abuse, illness in household, parental divorce, no parental affection, and dysfunctional family. Extra-familial ACEs included physical violence or negative recognition by teachers, being bullied in elementary or junior high school, or sexual violence. RESULTS: The frequency of psychosomatic disorders among the respondents was 14.8%. Among the 7 intra-familial ACEs, emotional abuse (relative risk, RR = 1.9) and illness in household (RR = 1.7) increased the risk of psychosomatic disorders. Estimates of the relative risk for the 5 extra-familial ACEs were statistically significant and ranged from 1.5 for being bullied in elementary school or physical violence from teachers to 2.4. Students who had 3 or more intra-familial ACEs and 2 or more extra-familial ACEs had a 3.0 relative risk for psychosomatic disorder. CONCLUSION: These results suggest that intra- and extra-familial ACEs are associated with the development of psychosomatic disorders. Therefore, sufficient evaluation of ACEs should be performed in adolescent patients with psychosomatic disorder

頚椎症性脊髄症症例における頚椎アライメント評価 : 坐位頚椎レントゲンと立位全脊椎レントゲンは等しく有用か?

Study Design: Retrospective review of medical charts and radiographic data. Objectives: We aimed to clarify the differences in cervical alignment findings between sitting cervical lateral radiographs and standing whole-spine lateral radiographs with clavicle positioning in cervical spondylotic myelopathy (CSM) patients. Methods: We retrospectively evaluated the radiographs of 50 consecutive patients who underwent cervical surgery for CSM in our hospital. Cervical sagittal alignment was evaluated based on the C0-2 angles and C2-7 Gore and Cobb angles. Head position was evaluated in terms of the center of gravity of the head to C7 (CGH-C7) angle and the McGregor angle (ie, the angle between the McGregor line and a horizontal line). The T1-slope was also evaluated. Results: The mean values of the CGH-C7 angle and T1-slope were significantly lower, while the mean value of the McGregor angle was significantly higher on whole-spine lateral radiographs with clavicle positioning than on sitting cervical lateral radiographs. The mean values of the C0-2 and C2-7 angles did not differ significantly between the 2 radiographic positioning approaches. Conclusions: Using whole-spine lateral radiographs with clavicle positioning may result in a significantly lower T1-slope and a posterior tilt of the head. In the absence of a compensatory change in cervical alignment, clavicle positioning may force patients to adopt an upward gazing position of the head. These compensatory mechanisms should be considered while evaluating cervical alignment on whole-spine lateral radiographs with clavicle positioning. Surgical planning should take into account the effect of posture on the radiographic appearance of cervical alignment.博士（医学）・甲第702号・平成31年3月15日© The Author(s) 2018.

The effects of repeated thermal therapy for two patients with chronic fatigue syndrome

Abstract Objective: This paper describes the successful treatment of two patients with chronic fatigue syndrome (CFS) using repeated thermal therapy. Methods: Two patients with CFS underwent treatment with prednisolone (PSL), with no satisfactory effect. They were subjected to thermal therapy that consisted of a far-infrared ray dry sauna at 60 8C and postsauna warming. The therapy was performed once a day, for a total of 35 sessions. After discharge, these subjects continued the therapy once or twice a week on an outpatient basis for 1 year. Results: Symptoms such as fatigue, pain, sleep disturbance, and low-grade fever were dramatically improved after 15 to 25 sessions of thermal therapy. Although PSL administration was discontinued, the subjects showed no relapse or exacerbation of symptoms during the first year after discharge. The patients became socially rehabilitated 6 months after discharge. Conclusions: These results suggest that repeated thermal therapy might be a promising method for the treatment of CFS.

骨髄間葉系細胞シートはラット脊髄離断損傷後にグリア瘢痕形成を抑制し、軸索再生と後肢運動機能改善を促進する。

OBJECTIVE Transplantation of bone marrow stromal cells (BMSCs) is a theoretical potential as a therapeutic strategy in the treatment of spinal cord injury (SCI). Although a scaffold is sometimes used for retaining transplanted cells in damaged tissue, it is also known to induce redundant immunoreactions during the degradation processes. In this study, the authors prepared cell sheets made of BMSCs, which are transplantable without a scaffold, and investigated their effects on axonal regeneration, glial scar formation, and functional recovery in a completely transected SCI model in rats. METHODS BMSC sheets were prepared from the bone marrow of female Fischer 344 rats using ascorbic acid and were cryopreserved until the day of transplantation. A gelatin sponge (GS), as a control, or BMSC sheet was transplanted into a 2-mm-sized defect of the spinal cord at the T-8 level. Axonal regeneration and glial scar formation were assessed 2 and 8 weeks after transplantation by immunohistochemical analyses using anti-Tuj1 and glial fibrillary acidic protein (GFAP) antibodies, respectively. Locomotor function was evaluated using the Basso, Beattie, and Bresnahan scale. RESULTS The BMSC sheets promoted axonal regeneration at 2 weeks after transplantation, but there was no significant difference in the number of Tuj1-positive axons between the sheet- and GS-transplanted groups. At 8 weeks after transplantation, Tuj1-positive axons elongated across the sheet, and their numbers were significantly greater in the sheet group than in the GS group. The areas of GFAP-positive glial scars in the sheet group were significantly reduced compared with those of the GS group at both time points. Finally, hindlimb locomotor function was ameliorated in the sheet group at 4 and 8 weeks after transplantation. CONCLUSIONS The results of the present study indicate that an ascorbic acid-induced BMSC sheet is effective in the treatment of SCI and enables autologous transplantation without requiring a scaffold.博士（医学）・甲第656号・平成28年11月24日© Copyright 2016 American Association of Neurological SurgeonsThe definitive version is available at " http://dx.doi.org/10.3171/2016.8.SPINE16250

An isoflavone catabolism gene cluster underlying interkingdom interactions in the soybean rhizosphere

ダイズ根圏細菌のイソフラボン代謝遺伝子クラスターを発見--根圏形成メカニズムの理解や有用物質生産に貢献--.京都大学プレスリリース. 2024-04-24.Plant roots secrete various metabolites, including plant specialized metabolites, into the rhizosphere, and shape the rhizosphere microbiome, which is crucial for the plant health and growth. Isoflavones are major plant specialized metabolites found in legume plants, and are involved in interactions with soil microorganisms as initiation signals in rhizobial symbiosis and as modulators of the legume root microbiota. However, it remains largely unknown the molecular basis underlying the isoflavone-mediated interkingdom interactions in the legume rhizosphere. Here, we isolated Variovorax sp. strain V35, a member of the Comamonadaceae that harbors isoflavone-degrading activity, from soybean roots and discovered a gene cluster responsible for isoflavone degradation named ifc. The characterization of ifc mutants and heterologously expressed Ifc enzymes revealed that isoflavones undergo oxidative catabolism, which is different from the reductive metabolic pathways observed in gut microbiota. We further demonstrated that the ifc genes are frequently found in bacterial strains isolated from legume plants, including mutualistic rhizobia, and contribute to the detoxification of the antibacterial activity of isoflavones. Taken together, our findings reveal an isoflavone catabolism gene cluster in the soybean root microbiota, providing molecular insights into isoflavone-mediated legume–microbiota interactions

Biceps-Related Physical Findings Are Useful to Prevent Misdiagnosis of Cervical Spondylotic Amyotrophy as a Rotator Cuff Tear

Study DesignCase–control study.PurposeThe aim of the present study was to identify physical findings useful for differentiating between cervical spondylotic amyotrophy (CSA) and rotator cuff tears to prevent the misdiagnosis of CSA as a rotator cuff tear.Overview of LiteratureCSA and rotator cuff tears are often confused among patients presenting with difficulty in shoulder elevation.MethodsTwenty-five patients with CSA and 27 with rotator cuff tears were enrolled. We included five physical findings specific to CSA that were observed in both CSA and rotator cuff tear patients. The findings were as follows: (1) weakness of the deltoid muscle, (2) weakness of the biceps muscle, (3) atrophy of the deltoid muscle, (4) atrophy of the biceps muscle, and (5) swallow-tail sign (assessment of the posterior fibers of the deltoid).ResultsAmong 25 CSA patients, 10 (40.0%) were misdiagnosed with a rotator cuff tear on initial diagnosis. The sensitivity and specificity of each physical finding were as follows: (1) deltoid weakness (sensitivity, 92.0%; specificity, 55.6%), (2) biceps weakness (sensitivity, 80.0%; specificity, 100%), (3) deltoid atrophy (sensitivity, 96.0%; specificity, 77.8%), (4) biceps atrophy (sensitivity, 88.8%; specificity, 92.6%), and (5) swallow-tail sign (sensitivity, 56.0%; specificity, 74.1%). There were statistically significant differences in each physical finding.ConclusionsCSA is likely to be misdiagnosed as a rotator cuff tear; however, weakness and atrophy of the biceps are useful findings for differentiating between CSA and rotator cuff tears to prevent misdiagnosis

Clinical Significance of Serum Soluble T Cell Regulatory Molecules in Clear Cell Renal Cell Carcinoma

To clarify the role of serum soluble T cell regulatory molecules in clear cell renal cell carcinoma (CCRCC), we measured the serum levels of soluble interleukin-2 receptor (sIL-2R), soluble B7-H3 (sB7-H3), and soluble cytotoxic T lymphocyte associated antigen-4 (sCTLA-4) in 70 CCRCC patients and 35 healthy controls. We investigated correlations between the serum levels of these soluble T cell regulatory molecules and the pathological grade, clinical stage, and prognosis of CCRCC. We also assessed the relations among each of these soluble molecules. As a result, the serum level of sIL-2R was significantly higher in CCRCC patients than in healthy controls ( < 0.05). In addition, elevation of serum sIL-2R was significantly correlated with the clinical stage ( < 0.001), and the survival of patients with high sIL-2R levels was shorter than that of patients with low sIL-2R levels ( < 0.05). Furthermore, the serum level of sB7-H3 was also significantly correlated with the clinical stage ( < 0.05), while the sIL-2R and sB7-H3 levels showed a positive correlation with each other ( = 0.550, < 0.0001). These results indicate that the serum level of sIL-2R reflects tumor progression in CCRCC patients. In addition, the possibility was suggested that the IL-2/IL-2R and B7-H3 pathways may be involved in the progression of CCRCC

A Case of Renal Angiomyolipoma with Minimal Fat Mimicking Renal Cell Carcinoma

We present a case of renal angiomyolipoma (AML) with minimal fat mimicking renal cell carcinoma(RCC). AML is composed of variable amount of fat, smooth muscle and abnormal blood vessels. In general,AML can be differentiated from RCC with great accuracy using modern radiological techniques due to thefat component of the renal mass. In the present case, the renal tumor did not demonstrate intratumoral faton radiological studies. Surgery was performed and the renal tumor was removed. Histologically, the renaltumor showed abundant muscle that occupied almost the entire lesion, which demonstrated HMB-45 antigen.The tumor was diagnosed as renal AML

術後4日目リンパ球数と7日目CRP値は信頼度の高い有用な手術部位感染の指標である : 脊椎後方インストゥルメンテーション手術における検討

STUDY DESIGN: A case-control study. OBJECTIVE: The objective of this study is to identify biochemical markers for surgical site infection (SSI) in posterior instrumented spinal fusion that are not affected by operative circumstances and to determine diagnostic cutoffs for these markers. SUMMARY OF BACKGROUND DATA: Numerous biochemical markers may be used for early detection of SSI; however, these markers may be affected by operative factors. METHODS: We reviewed data on C-reactive protein level and total white blood cell count and differential count before instrumented spinal fusion and at 1, 4, and 7 days postoperatively. The 141 patients in our sample were divided into an SSI group (patients who developed deep SSI) and a no-SSI group. We determined which markers differed significantly between groups and identified those not affected by operative circumstances (operating time, intraoperative blood loss, number of fusion segments) in the no-SSI group. Then, we determined diagnostic cutoffs for these unaffected markers by using receiver-operating characteristic curves. RESULTS: Three markers were selected: lymphocyte count at 4 days postoperatively (cutoff 1180/μL, sensitivity 90.9%, specificity 65.4%, area under the curve [AUC] 0.80), lymphocyte count of at 7 days postoperatively (cutoff 4.4 mg/dL, sensitivity 90.9%, specificity 89.2%, AUC 0.95). CONCLUSION: Lymphocyte count at 4 and 7 days postoperatively and C-reactive protein level at 7 days postoperatively are reliable markers for SSI following instrumented spinal fusion. Lymphocyte count at 4 days should be useful for screening because of its high sensitivity and because it can be measured early. C-reactive protein level at 7 days should be useful for definitive diagnosis given its high sensitivity and specificity and large AUC.博士（医学）・甲第654号・平成28年7月8日Copyright © 2016 Wolters Kluwer Health, Inc.
