Analysis of Pretreatment Factors Associated with Stability in Early Class III Treatment
BACKGROUND: The purpose of this study was to identify pretreatment factors associated with the stability of early class III treatment, since most orthodontists start the treatment with their uncertain hypotheses and/or predictions. Subjects consisted of 75 patients with a class III skeletal relationship (ANB \u3c 2° and overjet \u3c 0 mm) who had been consecutively treated with rapid maxillary expansion and facemask and followed until their second phase treatment. The patients were divided into two groups according to whether they showed relapse in follow-up. The stable group maintained their positive overjet (n = 55), and the unstable group experienced relapse with a zero or negative overjet (n = 20). Two general, three dental, and 13 cephalometric pretreatment factors were investigated to determine which factors were associated with stability.
RESULTS: Sex, pretreatment age, and anteroposterior functional shift, which were hypothesized as associated factors, were not related to the stability of early class III treatment. Significant differences were detected between the two groups in the horizontal distance between the maxillary and mandibular molars in centric relation. Cephalometric variables, such as the mandibular length (Ar-Me), Wits appraisal, SN to ramus plane angle (SN-Rm), gonial angle, incisor mandibular plane angle (IMPA), and Frankfort plane to mandibular incisor angle (FMIA) showed significant differences between the groups. The horizontal distance was the most influential factor by logistic regression analysis.
CONCLUSIONS: Hypothesis (related to sex, age, functional shift) were rejected. Several cephalometric factors related to the mandible were associated with stability. The horizontal distance between the maxillary and mandibular molars in centric relation was the best predictor of early class III treatment relapse
Relationship of Physical Activity to Self-Care Agency and Physical Condition Among Older Adults in a Rural Area
[Background] Maintaining physical activity is important for older adults. “Self-care agency” is the ability to perform self-care, which is defined as people following their own will, managing themselves, and maintaining activities. We investigated the relationship among physical activity and self-care agency, demographic factors and physical condition in older adults. [Methods] Self-care agency was assessed by using the Self-Care Agency Questionnaire developed for Japanese patients with chronic diseases. Among 175 older adults aged 65 years or older living in a rural area, responses from 83 who performed physical activities were analyzed. Correspondence analysis was conducted to characterize demographic factors and self-care agency. [Results] A higher proportion of women than men were engaged in physical activity. Irrespective of age and sex, many of the participants performed stretching exercises, walking, radio exercises, TV exercises, and participated in community circles. Participants who engaged in physical activities had significantly higher self-care agency scores than inactive participants. Among the active participants, the self-care agency score was significantly higher for women than men (P = .04) and was also significantly higher for participants aged ≥ 75 years compared to those aged < 75 years. Individuals with a high self-care agency tended to participate in local programs and perform brief physical activities at home. [Conclusion] Physically active older adults demonstrated high self-care agency. Their activities were easily carried out in their daily lives, with activities varying by age and sex. Support from community health experts is needed to promote suitable physical activity among older adults tailored for age and sex, especially among older adults who have low self-care agency

ヒト大腸癌肝転移におけるHVEM発現の重要性について
Background: Herpesvirus entry mediator (HVEM) has been suggested to play various roles in cancer biology. The authors report that HVEM expression in tumor cells is associated with a reduction in the number of tumor-infiltrating lymphocytes and a poor prognosis after surgical resection in various human gastrointestinal cancers. This study aimed to clarify the clinical significance of HVEM expression in human colorectal liver metastasis (CRLM). Methods: This study examined the cases of 104 patients with CRLM who underwent curative liver resection at Nara Medical University between 2000 and 2014. The median follow-up period was 50.2 months. Immunohistochemical staining was performed using antibodies against HVEM, CD4, CD8, and CD45RO. Results: High HVEM expression was observed in 49 patients (47.1%) with CRLM. Expression of HVEM was not associated with age, gender, administration of preoperative chemotherapy, tumor size, number of tumors, or histologic differentiation. The high-HVEM group exhibited significantly worse overall survival (OS) than the low-HVEM group (P = 0.002). Multivariate analysis showed that high HVEM expression in CRLM, age of 70 years or older, and having five or more tumors are independent poor prognostic factors for OS (hazard ratio [HR], 3.35; 95% confidence interval [CI], 1.41-7.93; P = 0.006). The number of tumor-infiltrating CD8+ and CD45RO+ T cells was significantly lower in the high-HVEM group than in the low-HVEM group. High HVEM expression in primary colorectal cancer was significantly associated with synchronous CRLM, but not with metachronous CRLM. Conclusions: Tumor HVEM expression might play a critical role in CRLM.博士(医学)・乙第1447号・令和元年12月5日© Society of Surgical Oncology 2019This is a post-peer-review, pre-copyedit version of an article published in Annals of surgical oncology.
