| Abstract | Cervical spondylotic myelopathy (CSM) and ossification of the posterior longitudinal ligament (OPLL) increase the likelihood of spinal cord injury without radiographic evidence of trauma (SCIWORET). Opinions regarding the optimal timing for surgery in such cases vary, however. We retrospectively investigated the demographics and outcomes of patients with SCIWORET who underwent surgery shortly after experiencing rapid neurological deterioration, and we matched patients who underwent standby surgery for CSM or OPLL. Although the optimal timing of surgery for SCIWORET remains unclear, our findings suggest that early stage surgery for SCIWORET may yield favorable neurological improvements. |

| Abstract | This study investigated the risk factors for bone fragility and perioperative periprosthetic femoral stem fractures in patients undergoing hip arthroplasty for femoral neck fractures. The records of 215 patients (42 male, 173 female; mean age, 84.4 years) were analyzed to assess correlations among periprosthetic fracture rates and sex, age, body mass index (BMI), Dorr classification, femoral stem fixation type (cemented/cementless), and bone mineral density (BMD) of the contralateral proximal femur. The overall prevalence of perioperative periprosthetic fractures was 4.7%. All patients with periprosthetic fractures were female, and all but one were ≥ 80 years of age. Fracture rates were higher in patients with lower BMI, although this difference was not significant. The fracture rates were 0%, 4.7%, and 7.9% for Dorr types A, B, and C, respectively, and 0% and 5.3% for patients who received cemented and cementless stems, respectively. The findings indicated that female patients, those of advanced age, those with lower BMI, and those with Dorr type C had lower BMDs. Although BMD was significantly lower in patients who received cemented stems compared to those who received cementless stems, no fractures were observed in the former group, suggesting that the use of cemented stems is safe for this high-risk population. |

| Abstract | We investigated the work productivity levels of employed cancer survivors and non-cancer-survivor workers by conducting a cross-sectional study in Japan between February and March 2019, using an online survey. A total of 561 employed individuals aged 20-64 years were analyzed. Work productivity was assessed using the Work Productivity and Activity Impairment-General Health questionnaire which evaluates absenteeism, presenteeism, and overall work productivity loss. The questionnaire responses demonstrated that the cancer survivors within 1 year of diagnosis had significantly higher absenteeism compared to the non-cancer workers (p=0.048). Although presenteeism and overall work productivity loss were also higher in the non-cancer-survivor group, the differences were not significant. Cancer survivors within 1 year of diagnosis exhibited higher absenteeism, but their work productivity appeared to recover to levels comparable to those of the non-cancer workers over time. These findings may contribute to workplace policies supporting cancer survivors’ return to work. |

| Abstract | Bloodstream infections (BSIs) are an important cause of morbidity and mortality in geriatric patients. We retrospectively analyzed the cases of geriatric patients who developed BSIs due to gram-negative bacteria in order to evaluate the epidemiology, antimicrobial resistance, and the factors affecting mortality. The cases of 110 patients aged ≥ 65 years admitted to our hospital between January 1, 2017, and December 31, 2022 were assessed; 70 (63.6%) of the BSIs were healthcare-associated BSIs. The urinary system was the most common detectable source of infection at 43.6%. The most frequently isolated bacteria were Escherichia coli, Pseudomonas aeruginosa, and Klebsiella pneumoniae, in that order. Carbapenem resistance was detected in 17 patients (15.5%), and extended-spectrum beta-lactamase (ESBL) production from Enterobacterales family members was detected in 37 (51.4%) patients. Multivariate analysis revealed that (i) the probability of mortality in the patients with total bilirubin was increased by approx. sixfold and (ii) the likelihood of mortality for those with a Pitt bacteremia score (PBS) ≥ 4 points was approx. 17 times higher. PBS and simplified qPitt scores can help predict mortality and manage geriatric patients. There is a significant increase in mortality among patients with procalcitonin (PCT) levels at ≥ 2 nm/ml. |

| Abstract | Extracorporeal cardiopulmonary resuscitation (ECPR) has evolved into a life-saving therapy for select cardiac arrest patients, yet a growing body of evidence suggests it also holds promise as a bridge to organ donation in non-survivors. This review explores the clinical outcomes, ethical complexities, and evolving policies surrounding organ donation after ECPR. We summarize recent international and Japanese data demonstrating favorable graft function from ECPR donors, with the exception of lung transplantation. The ethical challenges — particularly those involving brain death determination on extracorporeal membrane oxygenation and adherence to the dead donor rule — are discussed in the context of Japan’s recent regulatory reforms. Additionally, we highlight the importance of structured end-of-life communication through multidisciplinary team meetings in facilitating ethically sound transitions from rescue efforts to donation pathways. Moving forward, improvements in donor management, standardized legal frameworks, and public and professional education are essential to optimizing the life-saving and life-giving potential of ECPR. |

| Abstract | Renal cell carcinoma (RCC) can metastasize hematogenously and recur after a long dormancy. Chromophobe RCC metastasized to the cervical lymph nodes 10 years after the primary resection in a woman who underwent nephrectomy for RCC (T1aN0M0 stage I). Metastatic RCC diagnosis was confirmed by aspiration. The lymph node mass was resected, and the tumor cells matched chromophobe RCC metastasis. No adjuvant therapy was administered due to the lack of evidence regarding adjuvant therapy for chromophobe RCC. Long-term surveillance is crucial in RCC because of the possibility of late metastasis. We reviewed the clinical aspects and literature on metastatic cervical RCC. |

| Abstract | A 38-year-old man was brought to the hospital for emergency treatment of cyanosis. The patient exhibited generalized cyanosis and impaired consciousness despite adequate oxygen therapy. Arterial blood was black, and arterial blood gas analysis revealed an abnormally high methemoglobin level of 67.8%. We later interviewed his colleagues regarding his exposure to aniline while working at the factory and diagnosed him with methemoglobinemia due to aniline poisoning. The patient was administered methylene blue (MB) after being transferred to another hospital, where this treatment was available, resulting in an improvement in symptoms. Although rare, methemoglobinemia is serious. A good understanding of the circumstances at disease onset, characteristic findings, and abnormal values of methemoglobinemia is important. In addition, MB is an important therapeutic for the treatment of methemoglobinemia; if MB is not available at a particular hospital, transfer of the patient to a hospital that stocks MB should be considered. |

| Abstract | Perigraft seroma, a sterile fluid accumulation around the graft, is a potential complication after thoracic aortic surgery. The optimal treatment strategy for a perigraft seroma with vascular compression after thoracic aortic surgery has been unclear. We describe the case of a 62-year-old Japanese male in whom an asymptomatic perigraft seroma was observed after he had undergone aortic root replacement for annulo-aortic ectasia. The seroma was successfully treated with thoracoscopic drainage and conservative therapy. Less invasive therapy, including conservative therapy, may also be an option for asymptomatic perigraft seromas observed after thoracic aortic surgery. |

| Abstract | A 67-year-old woman with rheumatoid arthritis presented with an untriggered hematoma in the right shoulder joint. Radiographic findings showed humeral head collapse and destruction of the glenoid fossa with ectopic calcification. Calcium pyrophosphate deposition (CPPD) in the synovial fluid was observed using a polarizing microscope. Histopathological findings revealed chronic inflammatory cell infiltration and giant cells surrounded by CPPD. The patient was diagnosed with rapid destructive arthropathy (RDA). Endoscopic shoulder joint debridement was performed. Postoperatively, active flexion improved from 40 to 75 degrees. This case highlights that CPPD can cause RDA in the shoulder, detectable with detailed histopathology. |

| Abstract | We investigated the emotional changes that young patients with breast cancer need to undergo in order to foster relationship-building with their partners by conducting a qualitative descriptive study (March 1 to Nov. 26, 2021) and semi-structured interviews with eight postoperative patients (age 20-40 years) with breast cancer. The data were analyzed using the modified grounded theory approach (M-GTA), yielding five categories: (i) Awareness of being a breast cancer patient, (ii) Being at a loss, (iii) Support from significant others, (iv) The struggle to transition from being a patient with cancer to becoming “the person I want to be”, and (v) Reaching the “me” I want to be who can face building a relationship with a partner. These findings suggest that young breast cancer patients must feel that they can lead a normal life through activities such as work or acquiring qualifications before building relationships with their partners, and that getting closer to their desired selves is important. Nurses can provide information to young patients with breast cancer to assist them in building a solid relationship with their partners. We believe that this support may enhance the patients’ quality of life and help them achieve stronger relationships with their partners. |

| Abstract | 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. |

| Abstract | 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. |

| Abstract | 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. |

| Abstract | 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. |

| Abstract | 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. |

| Abstract | 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. |

| Abstract | 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. |

| Abstract | 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. |

| Abstract | 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. |
