In this cohort, 53% (278/521) of the patients who underwent breast conservative surgery (BCS) and 96% (124/129) of those treated with mastectomy did not receive POI. The patients who underwent BCS were treated with POI using opposing tangential field irradiation. A false negative (FN) SLN was retrospectively defined as a negative metastasis in SLN plus positive recurrence in the axillary lymph nodes. Recurrence was detected in 83 patients. A logistic regression analysis revealed that the nuclear grade (odds ratio [OR] 1.69), POI (OR 0.41), and postoperative hormone therapy (OR 0.40) were each significantly related to recurrence. The 26.1% (12/46) FN rate of the non-POI patients decreased to 5.8% (1/17) compared to those treated with POI. The rate of axillary recurrence was significantly lower in the POI group (0.4%) versus the non-POI group (2.7%) (p=0.0355). The rate of locoregional recurrence was also significantly lower in the POI group (2.0%) versus the non-POI group (13.4%) (p<0.0001). No significant difference was observed in the rate of distant recurrence between the POI (4.0%) and non-POI (3.3%) (p=0.831) groups. These results indicated that the postoperative opposing tangential field irradiation of conserved breast tissue inhibited recurrence in the axillary lymph nodes.","PeriodicalId":7017,"journal":{"name":"Acta medica Okayama","volume":"79 2","pages":"101-107"},"PeriodicalIF":0.6,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143962415","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Advances in CT technology have improved diagnostic imaging quality, but reduction of radiation exposure remains a goal. We evaluated the potential for radiation dose reduction in temporal bone CT examinations using porcine ear ossicles and a photon-counting detector CT system. Three scans of the bilateral temporal bone were performed on each of three pig cadaver heads. In each of seven successive imaging sessions, the radiation dose was reduced by an additional one-seventh of the recommended dose (RD). Two board-certified radiologists independently scored the resulting images on a scale of 1 to 5 points, where 5 represented the image quality at the RD. Images scoring ≥4.5 points were considered acceptable. Noise was assessed in a 2-cm-diameter region near the ear ossicles, and standard deviation was measured for each of the seven decrements from the RD. As the radiation dose decreased, the noise progressively increased, and visual assessment scores progressively decreased. Acceptable image scores were obtained at six-sevenths (4.9), five-sevenths (4.8), four-sevenths (4.7), and three-sevenths (4.6) of the RD. Thus, acceptable porcine temporal bone CT images were obtained with a radiation dose reduction of approximately 50%.","PeriodicalId":7017,"journal":{"name":"Acta medica Okayama","volume":"79 2","pages":"75-80"},"PeriodicalIF":0.6,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143962416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The timing of the initiation of ANAM treatment is crucial to its efficacy. Although the body mass index (BMI) is a diagnostic criterion for cancer cachexia, no studies have explored its association with ANAM efficacy. We conducted a single-center, retrospective cohort study to investigate the association between the pre-treatment BMI and ANAM efficacy in patients with cancer-associated cachexia (n=47). The ANAM treatment was considered effective if the patient's appetite improved within 30 days of treatment initiation. We calculated a BMI cutoff value (19.5 kg/m2) and used it to divide the patients into high- and low-BMI groups. Their background, clinical laboratory values, cancer types, and treatment lines were investigated. Twenty (42.6%) had a high BMI (≥ 19.5 kg/m2) and 27 (57.4%) had a low BMI (< 19.5 kg/m2). High BMI was significantly associated with ANAM effectiveness (odds ratio 7.86, 95% confidence interval 1.99-31.00, p=0.003). Together these results indicate that it is beneficial to initiate ANAM treatment before a patient's BMI drops below 19.5 kg/m2. Our findings will help advance cancer cachexia treatment and serve as a reference for clinicians to predict ANAM's efficacy.","PeriodicalId":7017,"journal":{"name":"Acta medica Okayama","volume":"79 2","pages":"65-73"},"PeriodicalIF":0.6,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143960742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We examined cross-sectional relationships between work engagement and major health outcomes among junior and senior high school teachers in Japan via a nationwide survey in 2019-2020. A total of 3,160 respondents were included in the analyses (19.9% response rate). Work engagement was assessed with the Utrecht Work Engagement Scale-9 (UWES-9), and we thus divided the teachers into quartiles according to their UWES-9 scores. Based on validated questionnaires, we assessed insomnia, psychological distress, and neck pain as health outcomes. A binomial logistic regression adjusted for age, gender, school type, teacher's roles, involvement in club activities, division of duties, employment status, and whether they lived with family demonstrated that the teachers with lower UWES-9 scores had higher burdens of insomnia, psychological distress, and neck pain (odds ratios [95% confidence intervals] in 4th vs. 1st quartile, 2.92 (2.34-3.65), 3.70 (2.81-4.88), and 2.12 (1.68-2.68), respectively; all trend p<0.001). There were no significant differences in these associations between full-time and part-time teachers.

The assessment was performed during their children's 4-month health examination. The relationships between postpartum depression and the mothers' background factors and scores on the Big Five personality traits scale were also examined. Of the Big Five personality traits, the scores for neuroticism were significantly higher in the ART group (n=71) than in the general infertility treatment (n=118) and natural pregnancy (n=872) groups. No significant differences in EPDS scores were seen among these three groups. A logistic regression analysis showed that neuroticism was associated with an EPDS score ≧9 points, (which is suggestive of postpartum depression, ) in all groups. Moreover, although a long-standing marriage had an inhibitory effect on postpartum depression in the natural pregnancy group, no such trend was seen in the ART group, which included many women with long-standing marriages. Particularly for women who become pregnant by ART, an individualized response that pays close attention to the woman's personality traits is needed.","PeriodicalId":7017,"journal":{"name":"Acta medica Okayama","volume":"79 2","pages":"109-116"},"PeriodicalIF":0.6,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143963215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
