抄録 The position attained in total hip arthroplasty (THA) is ideally in the center of the horizontal plane of the acetabulum. However, central placement is not always possible. We hypothesized that differences in approach result in individual differences in cup positioning; thus, we investigated the cup positions of 217 hips that underwent THA. The acetabulum’s anteroposterior diameter was measured, and the cups placed within 2 mm of the line perpendicular to the center as a central placement (central). Of the 217 hips, 68, 114, and 35 hips were anterior, central, and posterior, respectively. In 21 hips, anteroposterior deviation was noted. Among patients operated using the anterolateral approach, 48, 93, and 30 hips were anterior, central, and posterior, respectively. Among those operated using the posterolateral approach, 16, 20, and 4 hips were anterior, central, and posterior, respectively. The cup position shifted either anteriorly or posteriorly to the acetabulum in approximately half of all hips operated using both approaches and tended to shift anteriorly in the hips operated using the posterolateral approach. During THA surgery, it is important to operate with awareness of the center of the acetabulum.

抄録 This prospective observational study investigated the clinical status of patients with advanced non-small cell lung cancer (NSCLC) treated with cytotoxic chemotherapy+an immune checkpoint inhibitor (chemo + IO) as first-line treatment in a real-world setting. The cases of 98 patients treated with chemo + IO were prospectively collected and analyzed for effectiveness and safety. The response rate to chemo + IO was 46.9%, and the disease control rate was 76.5%. The median progression-free survival and overall survival (OS) in the total population were 5.2 and 22.3 months, respectively. The patients positive for PD-L1 (≥ 1%) showed significantly longer OS than the negative group (<1%) (median 26.7 vs. 18.7 months, p=0.04). Pre-existing interstitial lung disease (ILD) was associated with shorter OS than the absence of ILD (median 9.0 vs. 22.6 months, p<0.01). Immunerelated adverse events (irAEs) were observed in 28 patients (28.6%). The most frequent irAE was ILD (n=11); Grade 1 (n=1 patient), G2 (n=5), G3 (n=4), and only a single patient with a G5 irAE. In this CS-Lung-003 study, first-line chemo + IO in a real-world setting showed good effectiveness, comparable to that observed in international clinical trials. In real-world practice, chemo + IO is a promising and steadfast strategy.

抄録 Chondrocytes are responsible for the production of extracellular matrix (ECM) components such as collagen type II alpha-1 (COL2A1) and aggrecan, which are loosely distributed in articular cartilage. Chondrocyte dysfunction has been implicated in the pathogenesis of rheumatic diseases such as osteoarthritis (OA) and rheumatoid arthritis (RA). With age, advanced glycation end products (AGEs) accumulate in all tissues and body fluids, including cartilage and synovial fluid, causing and accelerating pathological changes associated with chronic diseases such as OA. Glycolaldehyde-derived AGE (AGE3), which is toxic to a variety of cell types, have a stronger effect on cartilage compared with other AGEs. To understand the long-term effects of AGE3 on cartilage, we stimulated a human chondrosarcoma cell line (OUMS-27), which exhibits a chondrocytic phenotype, with 10 μg/ml AGE3 for 4 weeks. As a result, the expressions of COL2A1 and aggrecan were significantly downregulated in the OUMS-27 cells without inducing cell death, but the expressions of proteases that play an important role in cartilage destruction were not affected. Inhibition of the receptor for advanced glycation end products (RAGE) suppressed the AGE3-induced reduction in cartilage component production, suggesting the involvement of RAGE in the action of AGE3.

抄録 Pathogens or their components can induce long-lasting changes in the behavior of innate immune cells, a process analogous to “training” for future threats or environmental adaptation. However, such training can sometimes have unintended consequences, such as the development of autoimmunity. Systemic lupus erythematosus (SLE) is a chronic and heterogeneous autoimmune disease characterized by the production of autoantibodies and progressive organ damage. Innate immunity plays a central role in its pathogenesis, contributing through impaired clearance of apoptotic cells, excessive type I interferon production, and dysregulated formation of neutrophil extracellular traps. Recent studies have revealed that metabolites and nucleic acids derived from mitochondria, a crucial energy production site, directly regulate type I interferon and anti-inflammatory cytokine production. These insights have fueled interest in targeting metabolic pathways as a novel therapeutic approach for SLE, offering promise for improving long-term patient outcomes.

抄録 In thoracic esophageal cancer, lymph node dissection around the recurrent laryngeal nerve is crucial but poses a risk of nerve palsy, affecting postoperative quality of life. In cases with an aberrant right subclavian artery (ARSA), the right recurrent laryngeal nerve is absent, and the non-recurrent inferior laryngeal nerve (NRILN) enters the larynx directly from the vagus nerve in the cervical region. Identifying the course of the NRILN is vital to avoid injury. A case of esophageal cancer with an ARSA, in which the course of the NRILN was preserved using the Nerve Integrity Monitoring (NIM) system during surgery, is described.

抄録 Cardiac calcified amorphous tumor (CAT) is a rare, benign non-neoplastic mass of the heart that is sometimes found due to embolic events. Most cases of CAT are treated with surgical removal to prevent future embolic events. However, the treatment strategy for CAT complicated by atrial fibrillation has remained to be determined. Here we report a case of left ventricular CAT complicated by paroxysmal atrial fibrillation (PAF) that was successfully treated with surgical removal and pulmonary vein isolation. Pulmonary vein isolation can be a simple and effective procedure for PAF, even during surgical removal of CAT.

抄録 A 66-year-old woman presented with significant anterior capsule contraction and intraocular lens dislocation in both eyes 4 months after cataract surgery. Postoperative examinations such as fluorescein angiography, Goldmann perimetry, and electroretinography revealed retinitis pigmentosa (RP). Patients with significant anterior capsule contraction after cataract surgery should be closely examined because RP may be a contributing factor.

抄録 A 78-year-old woman presented with sudden vision loss and central scotoma. Visual acuity in the right eye was 20/222, with submacular hemorrhage (SMH) and Henle fiber layer hemorrhage (HFLh) due to retinal arterial macroaneurysm (RAM) rupture. She underwent SMH displacement, including cataract surgery, vitrectomy, intravitreal injection of tissue-plasminogen activator, and air tamponade. Three months postoperatively the SMH and HFLh had disappeared and visual acuity had improved to 20/200. Six months postoperatively, a macular hole had developed. We performed an inverted internal limiting membrane flap and gas tamponade. Ten months later, the hole had closed and visual acuity had improved to 20/100.

抄録 Neural tube defects are common congenital anomalies, typically presenting early due to visible swelling and/or neurological deficits. Rarely, cystic swellings are neglected until adulthood, with only 14 cases of malignancy developing in an untreated meningomyelocele reported to date. We describe the case details of a 26-year-old Indian woman with this rare complication. Magnetic resonance imaging revealed a low-lying spinal cord with spinal dysraphism, cord herniation, and a cystic lesion. The biopsy confirmed a well-differentiated squamous cell carcinoma. Malignant transformation in an untreated myelomeningocele is rare, with chronic irritation and infection as proposed causes. Early biopsy and treatment are crucial for its management.

抄録 The status of postpartum depression was elucidated herein with the use of the Edinburgh Postnatal Depression Scale (EPDS) in women in Shikoku, Japan who became pregnant and gave birth after undergoing infertility treatment, including assisted reproductive technology (ART). 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.

抄録 To evaluate the effectiveness of postoperative irradiation (POI) for patients with cN0 early breast cancer, we retrospectively analyzed the cases of 650 consecutive breast cancer patients who underwent sentinel lymph node (SLN)-guided surgery (2005-2022) at our hospital. 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.

抄録 School teachers are subject to both physical and mental health problems. 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. Our findings indicate that low work engagement may contribute to physical and mental health issues among junior and senior high school teachers, thus providing insights for preventing health problems in this profession.

抄録 We retrospectively evaluated the oncologic outcomes of paclitaxel, cisplatin, and gemcitabine (PCG) with those of gemcitabine and cisplatin (GC) as neoadjuvant chemotherapy in muscle-invasive bladder cancer (MIBC) patients. The primary outcome was efficacy: pathological complete response (pCR), ypT0N0; and pathological objective response (pOR), ypT0N0, ≤ ypT1N0, or ypT0N1. Secondary outcomes included overall survival (OS), recurrence-free survival (RFS), predictive factors for pOR, OS, and RFS, and hematologic adverse events (AEs). Among 113 patients treated (PCG, n=28; GC, n=85), similar pOR and pCR rates were achieved by the groups (pOR: PCG, 57.1% vs. GC, 49. 4%; p=0.52; pCR: PCG, 39.3% vs. GC, 29.4%; p=0.36). No significant differences were observed in OS (p=1.0) or RFS (p=0.20). Multivariate logistic regression analysis showed that hydronephrosis (odds ratio [OR] 0.32, 95%CI: 0.11-0.92) and clinical node-positive status (cN+) (OR 0.22, 95%CI: 0.050-0.99) were significantly associated with a decreased probability of pOR. On multivariate Cox regression analyses, pOR achievement was associated with improved OS (hazard ratio [HR] 0.23, 95%CI: 0.10-0.56) and RFS (HR 0.30, 95%CI: 0.13-0.67). There were no significant between-group differences in the incidence of grade ≥ 3 hematologic AEs or dose-reduction required, but the PCG group had a higher incidence of grade 4 neutropenia.

抄録 Temporal bone computed tomography (CT) is frequently performed for pediatric patients with ear diseases. 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%.

抄録 Anamorelin (ANAM) is used to treat cancer-associated cachexia, a syndrome involving muscle loss and anorexia. 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.
