| 抄録 | Emicizumab, a bispecific monoclonal antibody, benefits patients with severe hemophilia A. It alters laboratory assessments of coagulation activity, requiring anti-idiotype monoclonal antibodies for accurate monitoring. A 64-year-old man, receiving emicizumab regularly, was admitted for laminoplasty. We planned to use FVIII replacement during the perioperative period after confirming the disappearance of inhibitors, monitoring coagulation activity with anti-idiotype monoclonal antibodies. Activated partial thromboplastin time was prolonged on postoperative day 2, prompting an immediate switch to eptacog alfa. The patient recovered without bleeding. This case underscores the necessity of anti-idiotype monoclonal antibodies for accurate monitoring. |

| 抄録 | The effect of weekend admission on patient mortality has been investigated in several therapeutic areas, including acute myeloid leukemia (AML), but the investigations’ results are controversial. We evaluated the relationship between in-hospital mortality and weekend admission in adult patients with AML in Japan by conducting a retrospective observational study using administrative data from 144 acute care hospitals from which patients were discharged between April 2014 and March 2019. The primary endpoint was in-hospital mortality, compared between weekend and weekday admissions. Among the 1,340 eligible patients, 11% (150) were admitted during a weekend. The in-hospital mortality rates of the patients admitted during weekends and those admitted on a weekday were 28% (42/150) and 17% (204/1190), respectively. After an adjustment for covariates, weekend admission was associated with a significantly higher risk of in-hospital mortality than weekday admission (HR 1.70, 95%CI: 1.20-2.40; p=0.003). However, such an association was not observed in patients treated in a bio-clean room (HR 1.26, 95%CI: 0.65-2.42). Our results demonstrate that for patients with AML, weekend admission was independently associated with a higher risk of death during hospitalization. An appropriate system is necessary for these patients. |

| 抄録 | Radon (222Rn; Rn) and thoron (220Rn; Tn) inhalation have been reported to enhance antioxidant activity in various organs. However, the effects of Tn on the colon have not been investigated. This study aimed to clarify the effects of Tn inhalation, alone and in combination with cyclosporin A (CsA), on dextran sulfate sodium (DSS)-induced colitis, and the accompanying oxidative stress, in mice. Male BALB/c mice were subjected to continuous 8-day Tn inhalation (c-Tn, 533±128 Bq/m3) or alternate-day Tn inhalation over the same period (f-Tn, 577±63Bq/m3), followed by treatment with 3% DSS and either CsA or vehicle for 7 days. Although the disease activity index (DAI) decreased significantly by day 2 in the c-Tn group, scores remained significantly higher than those in the f-Tn group. In the c-Tn group, superoxide dismutase and catalase activity in the colon were significantly elevated compared with those in sham controls. Thus, DSS-induced damage was effectively inhibited in the earlier stages by the c-Tn mode of inhalation than by the f-Tn mode. These findings suggest that continuous Tn inhalation more effectively attenuated early colitis symptoms than alternate-day inhalation, potentially through upregulation of antioxidant defenses. Tn and CsA showed no combined effects. |

| 抄録 | Trigonal meningiomas are rare and pose surgical challenges due to their deep location and proximity to critical neuroanatomical structures. We present the case of a 67-year-old woman with a growing trigonal meningioma successfully resected with guidance by a preoperative 3D imaging analysis system. Integration of CT and MRI including diffusion tensor imaging (DTI) enabled precise mapping of the optic radiation, guiding a middle temporal gyrus approach. Preoperative embolization reduced tumor vascularity, facilitating gross total resection with minimal blood loss. This case highlights the effectiveness of preoperative 3D imaging systems in optimizing surgical planning and improving outcomes in complex neurosurgical cases. |

| 抄録 | We report the case of a 72-year-old Japanese man with an incidental portal vein mass that was surgically resected and diagnosed as immunoglobulin G4 (IgG4)-related disease. The mass was discovered during an atrial fibrillation examination. The patient had a history of gastric cancer and was also diagnosed with rectal cancer, raising concerns about metastasis. Due to technical challenges, a biopsy was not feasible. Imaging findings suggested portal vein tumor thrombosis, complicating the diagnosis. This case highlights a rare presentation of IgG4-related disease mimicking portal vein tumor thrombus. |

| 抄録 | We applied unsupervised machine learning to analyze blood pressure (BP) and resting heart rate (HR) patterns measured during a 1-year period to assess their cross-sectional relationships with subclinical cerebral and renal target damage. Dimension reduction via uniform manifold approximation and projection, followed by K-means++ clustering, was used to categorize 362 community-dwelling participants (mean age, 56.2 years; 54.9% women) into three groups: Low BP and Low HR (Lo-BP/Lo-HR), High BP and High HR (Hi-BP/Hi-HR), and Low BP and High HR (Lo-BP/Hi-HR). Cerebral vessel lesions were defined as the presence of at least one of the following magnetic resonance imaging findings: lacunar infarcts, white matter hyperintensities, cerebral microbleeds, or intracranial artery stenosis. A high urinary albumin-to-creatinine ratio (UACR) was defined as the top 10% (≥ 12 mg/g) of the mean value from ≥2 measurements. Poisson regression with robust error variance, adjusted for demographics, lifestyle, and medical history, showed that the Hi-BP/Hi-HR group had relative risks of 3.62 (95% confidence interval, 1.75-7.46) for cerebral vessel lesions and 3.58 (1.33-9.67) for high UACR, and the Lo-BP/Hi-HR group had a relative risk of 3.09 (1.12-8.57) for high UACR, compared with the Lo-BP/Lo-HR group. These findings demonstrate the utility of an unsupervised, data-driven approach for identifying physiological patterns associated with subclinical target organ damage. |

| 抄録 | Single-position surgery with lateral lumbar interbody fusion (LLIF) and percutaneous pedicle screws (PPSs) is gaining attention for its reduced invasiveness. We developed SPAPS, a technique allowing two surgeons to perform anterior LLIF and posterior PPS insertion simultaneously in a single lateral decubitus position. This retrospective study compared SPAPS (SPAPS-LLIF, Group SL) and minimally invasive posterior/transforaminal lumbar interbody fusion (MIS-PLIF/TLIF, Group PT) in patients treated between 2016 and 2019 with a two-year follow-up. Operative time, estimated blood loss (EBL), length of hospital stay (LOS), JOABPEQ and VAS scores, segmental lordotic angle, lumbar lordotic angle, segmental Cobb’s angle, PPS misplacement, PPS loosening, fusion status, and muscle cross-sectional areas were compared. Fifty-two patients were analyzed (Group SL: 25; Group PT: 27). SPAPS significantly reduced operative time (118.0 vs. 165.3 min, p <0.01) and estimated blood loss (8.6 vs. 164.1 mL, p<0.01). While clinical outcomes and hospital stay were comparable, Group SL had significantly lower PPS loosening (0% vs. 13%, p<0.01) and non-union rates (0% vs. 22.2%, p=0.02). Multifidus muscle atrophy was also less in Group SL (−14.3 vs. −121.5 mm2, p<0.01). SPAPS demonstrated advantages in reducing surgical invasiveness without compromising clinical efficacy, offering a promising alternative to conventional posterior fusion surgery. |

| 抄録 | Clostridium perfringens is a pathogenic anaerobe that causes gas gangrene and food poisoning. Although autolysin-mediated reorganization of the bacterial cell wall is crucial for cell division, excessive autolysin activity induced by stressors can lead to cell lysis. In C. perfringens, air exposure is a significant stressor that causes cell lysis, and Acp (N-acetylglucosaminidase) is known to be a major autolysin. To further facilitate C. perfringens research, a technology to prevent air-induced cell lysis must be developed. This study investigated the role of Acp in air-induced autolysis and explored potential inhibitors that would prevent cell lysis during experimental procedures. Morphological analyses confirmed that Acp functions as an autolysin in C. perfringens, as acpdeficient strains exhibited filamentous growth. The mutants exhibited negligible autolysis under air-exposure stress, confirming the involvement of Acp in the autolytic process. We also evaluated the effects of various divalent cations on Acp activity in vitro and identified Zn2+ as a potent inhibitor. Brief treatment with a Zn2+- containing buffer induced dose-dependent cell elongation and autolysis inhibition in C. perfringens. These findings demonstrate that simple Zn2+ treatment before experiments stabilizes C. perfringens cells, reducing autolysis under aerobic conditions and facilitating various biological studies, except morphological analyses. |

| 抄録 | Primary graft dysfunction (PGD) is one of the major risk factors affecting patients’ short- and long-term survival after lung transplantation. No particular management strategy has been established for PGD; supportive care is the mainstay of PGD treatment. When a supportive strategy fails, the patient may require the introduction of extracorporeal membrane oxygenation (ECMO) as the last-resort measure for severe PGD. A variety of study of ECMO as a PGD treatment was reported and the management of PGD patients developed so far. Early recognition of a patient’s need for ECMO and its prompt initiation are critical to improved outcomes. The use of venovenous-ECMO became the preferred procedure for PGD rather than venoarterial-ECMO. However, the current ECMO strategy has limitations, and using ECMO to manage patients with PGD is not sufficiently effective. Further studies are required to develop this promising technology. |

| 抄録 | Bile leak occurs in 2-25% of liver transplant, 3-27% of hepatic resection, and 0.1-4% of cholecystectomy cases. The clinical course of bile leak varies depending on the type of surgery that caused the fistula, as well as the type, severity, and timing of bile duct injury. Although infections resulting from bile leak can be life-threatening, the introduction of endoscopic treatment has enabled some patients to avoid reoperation and has reduced the negative impact on quality of life associated with external fistulas for percutaneous drainage. Endoscopic interventions, such as sphincterotomy and stent placement, reduce the pressure gradient between the bile duct and duodenum, facilitating bile drainage through the papilla and promoting the closure of the leak. We reviewed the literature from 2004 to 2024 regarding bile leak following cholecystectomy and liver surgery, examining recommended techniques, timing, and treatment outcomes. In cases of bile leak following cholecystectomy, clinical success was achieved in 72-96% of cases, while success rates for bile leak following liver surgery ranged from 50% to 100%. Although endoscopic treatment is effective, it is not universally applicable, and its limitations must be carefully considered. |

| 抄録 | A 55-year-old obese Japanese male with left pneumothorax presented to our hospital. Bilateral pulmonary emphysema was confirmed. Persistent air leakage was observed, and a thoracoscopic bullectomy was performed. Although the thoracoscopic bullectomy was completed uneventfully, pre-extubation chest X-ray imaging indicated hyper-lucency occupying the right upper part of the thoracic cavity, suggesting right-sided pneumothorax. CT imaging indicated a right-upper-lobe expanded bulla. Extubation was performed, and the hyperinflated bulla gradually deflated. Careful management of bulla expansion and respiratory status may be necessary for patients with obesity and large bullae, especially in one-lung ventilation cases. |

| 抄録 | Pulmonary cement embolism (PCE) is a rare but severe complication following percutaneous vertebroplasty (PVP). Calcium phosphate cement (CPC) has emerged as an alternative to traditional materials for vertebral augmentation. There appear to be no established guidelines for managing symptomatic PCE, and there is scarce literature on CPC embolisms. This is a first report of a case of pulmonary CPC embolism following PVP. The patient, a 63-year-old Chinese female, was administered anticoagulant treatment and achieved a satisfactory outcome. Her case highlights the severe potential morbidity associated with CPC leakage and emphasizes the efficacy of anticoagulant treatment for managing pulmonary CPC embolisms. |

| 抄録 | A 76-year-old man presented with right eyelid swelling and deteriorated vision. Examination revealed anterior uveitis with hypopyon and a visual acuity of 20/2,000 in the right eye, with no abnormalities in the left. Computed tomography revealed enlargement of the right maxillary sinus and internal fluid accumulation, suggesting a postoperative maxillary cyst (POMC). Nasal endoscopic surgery drained the pus by opening the lower wall of the maxillary cyst. Following the procedure, intraocular inflammation resolved, and visual acuity in the right eye improved to 24/20. This is the first reported case of uveitis secondary to POMC. |

| 抄録 | The global femoral offset (the sum of the acetabular and femoral offsets) influences outcomes after total hip arthroplasty (THA). The optimal offset using plain radiographs has been reported, but internal and external rotations of the hip affect the offset value, producing unclear results when the nonsurgical side is not intact. We investigated the relationship between a functional hip score, i.e., the Harris Hip Score (HHS) and its effect on the post-THA anteroposterior and lateral offsets, and we sought to identify the optimal offset value. The cases of 158 patients with hemilateral hip osteoarthritis who underwent THA at a single center were retrospectively analyzed in this cross-sectional study. Three-dimensional pelvic and femoral models generated from computed tomography were used to examine several parameters, and the results revealed a significant binomial correlation among the modified HHS and femoral and global femoral offsets, with maximum values of 21.3 mm and 40 mm/100 cm body height, respectively. Pelvic and femoral parameters were measured and evaluated via alignment with a specific coordinate system. Our findings indicate that preoperative planning using these parameters may improve postoperative hip function, even when the nonoperative side is unsuitable for use as a reference, as in bilateral hip osteoarthritis cases. |

| 抄録 | 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. |

| 抄録 | 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. |

| 抄録 | 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. |

| 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 | 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. |
