| Abstract | We provide the first report of successful salvage surgery for a post-C1 laminectomy symptomatic recurrence of a retro-odontoid pseudotumor (ROP) that caused myelopathy. The 72-year-old Japanese woman presented with an ROP causing symptomatic cervical myelopathy. With ultrasonography support, we performed the enucleation of the ROP via a transdural approach and fusion surgery for the recurrence of the mass. At the final observation 2-year post-surgery, MRI demonstrated the mass’s regression and spinal cord decompression, and the patient’s symptoms had improved. Our strategy is an effective option for a symptomatic recurrence of ROP. |

| Abstract | We describe a floating technique via a posterolateral approach with intraoperative O-arm navigation to facilitate decompression of the spinal cord in thoracic myelopathy due to severe ossification of the posterior longitudinal ligament (OPLL). A 62-year-old man with myelopathy due to thoracic OPLL had left-leg muscle weakness, urinary disturbance, and spastic gait. Bilateral leg pain and gait disturbance had persisted for 2 years. He was successfully treated by the posterolateral OPLL floating procedure and posterior pedicle fixation under O-arm navigation. At a 2-year follow-up, manual muscle testing results and sensory function of the left leg had recovered fully. His cervical Japanese Orthopedic Association score had improved from 5/12 to 11/12. The novel intraoperative O-arm navigation-guided posterolateral floating procedure for thoracic OPLL is effective for achieving precise decompression and strong fixation with a posterior approach only and can provide an excellent result for severe thoracic OPLL without the risk of adverse events from intraoperative radiation. |

| Abstract | The diagnostic value of microRNA-377 (miR-377) in patients with acute coronary syndrome (ACS) and explored miR-377’s potential mechanisms. We performed an qRT-PCR to assess serum miR-377 levels in ACS patients and coronary artery ligation rat models. The diagnostic value of miR-377 was evaluated by determining the ROC curve. An ELISA assay was conducted to detect the model rat endothelial damage markers von Willebrand factor (vWF) and heart-type fatty acid binding protein (H-FABP), and proinflammatory cytokines TNF-α, IL-6, and IL-1β. The serum miR-377 level was elevated in the ACS patients and significantly increased in the ACS rats. MiR-377 has a high diagnostic value in ACS patients, with a 0.844 ROC, 76.47% specificity, and 87.10% sensitivity. MiR-377 was positively correlated with the expressions of vWF, H-FABP, cTnI, TNF-α, IL-6, and IL-1β. In ACS rats, reducing the expression of miR-377 significantly inhibited the increases in vWF, H-FABP, TNF-α, IL-6, and IL-1β. An elevated miR-377 level can be used as a diagnostic marker in patients with ACS. A reduction of miR-377 may alleviate ACS by improving myocardial damage such as endothelial injury and the inflammatory response. |

| Abstract | The failure of endodontic treatment is directly associated with microbial infection in the root canal or periapical areas. An endodontic sealer that is both bactericidal and biocompatible is essential for the success of root canal treatments. This is one of the vital issues yet to be solved in clinical dental practice. This in vitro study assessed the effectiveness of graphene oxide (GO) composites GO-CaF2 and GO-Ag-CaF2 as endodontic sealer materials. Dentin slices were coated with either the GO-based composites or commonly used root canal sealers (non-eugenol zinc oxide sealer). The coated slices were treated in 0.9% NaCl, phosphate-buffered saline (PBS), and simulated body fluid (SBF) at 37˚C for 24 hours to compare their sealing effect on the dentin surface. In addition, the radiopacity of these composites was examined to assess whether they complied with the requirements of a sealer for good radiographic visualization. Scanning electron microscopy showed the significant sealing capability of the composites as coating materials. Radiographic images confirmed their radiopacity. Mineral deposition indicated their bioactivity, especially of GO-Ag-CaF2, and thus it is potential for regenerative application. They were both previously shown to be bactericidal to oral microbes and cytocompatible with host cells. With such a unique assemblage of critical properties, these GO-based composites show promise as endodontic sealers for protection against reinfection in root canal treatment and enhanced success in endodontic treatment overall. |

| Abstract | The sodium glucose transporter 2 (SGLT2) inhibitor tofogliflozin is a glucose-lowering drug that causes the excretion of surplus glucose by inhibiting SGLT2. Because of tofogliflozin’s osmotic diuresis mechanism, patients’ serum electrolytes, body fluid levels, and cardiac function must be monitored. We retrospectively analyzed the cases of 64 elderly Japanese patients with type 2 diabetes mellitus (T2DM) who received tofogliflozin for 3 months. Their HbA1c, serum electrolytes (sodium, potassium, chloride), hematocrit, brain natriuretic peptide (cardiac volume load marker) and renin and aldosterone (RAA; an index of regulatory hormones involved in body fluid retention) were continuously monitored during the investigation period. Renal function and cardiac function (by echocardiography) were assessed throughout the period. HbA1c significantly decreased (β1=−0.341, p<0.0001, linear regression analysis [LRA]). Most of the hormonal, electrolyte, and physiological parameters were maintained throughout the study period. In these circumstances, E/e’ tended to decrease (β1=−0.382, p=0.13, LRA). Compared to the baseline, E/e’ was significantly decreased at 1 and 3 months (p<0.01, p<0.05). In the higher E/e’ group (E/e’≥10, n=34), E/e’ decreased significantly (β1=−0.63, p<0.05, LRA). ΔE/e’ was correlated with body-weight change during treatment (r=0.64, p<0.01). The 3-month tofogliflozin treatment improved glycemic control and diastolic function represented by E/e’ in T2DM patients, without affecting serum electrolytes, renal function, or RAA. No negative impacts on the patients were observed. Three-month tofogliflozin treatment lowered glucose and improved cardiac diastolic function. |

| Abstract | This study sought to identify factors that are predictive of a therapeutic response to hepatic arterial infusion chemotherapy (HAIC) by focusing on the number of prior transcatheter arterial chemoembolization (TACE) sessions. To determine the parameters predicting a good response to HAIC, we retrospectively analyzed 170 patients with hepatocellular carcinoma (HCC) who received HAIC regimens comprising low-dose cisplatin combined with 5-fluorouracil (LFP) or cisplatin (CDDP) for the first time. In both the LFP and CDDP regimens, the response rates were significantly lower in patients with three or more prior TACE sessions than in those with two or fewer prior TACE sessions (LFP 57% versus 28%; p=0.01, CDDP 27% versus 6%; p=0.01). Multivariable logistic regression analysis revealed that the number of prior TACE sessions (≥ 3) was significantly associated with non-responder status (odds ratio 4.17, 95% Confidence Interval (CI) 1.76-9.86) in addition to the HAIC regimen. Multivariable analysis using the Cox proportional hazards model revealed that a larger number of prior TACE sessions (≥ 3) was a significant risk factor for survival (hazard ratio 1.60, 95% CI 1.12-2.29) in addition to Child-Pugh class, serum alpha-fetoprotein concentration, and maximum diameter of HCC. HCC patients who receive fewer prior TACE sessions (≤ 2) were found to be better responders to HAIC. |

| Abstract | Taxanes are key drugs for patients with breast cancer. A major adverse effect of taxanes is peripheral neuropathy (PN). To investigate the ability of compression therapy using sleeves and stockings to prevent PN due to the taxane docetaxel, we conducted a single-center historical control trial. Patients receiving docetaxel at 75 mg/m2 every 3 weeks for 4 cycles as first-line chemotherapy for breast cancer were eligible. PN was evaluated using the common terminology criteria for adverse events version 4.0. The primary endpoint was the incidence of allgrade PN until 3 weeks after the fourth docetaxel administration. We evaluated 26 patients in the intervention group and compared their data to those collected retrospectively from 52 patients treated with docetaxel without compression. Neither the incidence of all-grade PN until 3 weeks after the fourth docetaxel administration (63.5% in the control group vs. 76.9% in the intervention group, p=0.31) nor that of PN grade ≥ 2 (13.5% vs. 15.4%, p=0.99) differed between the groups. In this study, the efficacy of compression therapy using sleeves and stockings to prevent PN induced by docetaxel was not demonstrated. Further clinical studies including medications or intervention are needed to reduce the incidence and severity of PN induced by chemotherapy. |

| Abstract | Chemotherapy is insufficient to treat macroscopic vascular invasion (MVI) of hepatocellular carcinoma (HCC). We retrospectively investigated the treatment outcomes of patients who underwent three-dimensional conformal radiotherapy (3D-CRT) for HCC MVI and analyzed prognostic factors by multivariate analysis using a Cox proportional hazard model. Sixty-five patients were studied. MVI sites were the portal vein (n=48 patients), portal and hepatic veins (n=8), and hepatic vein (n=9). The median irradiation dose was 50 Gy. The median survival time (MST) was 7.5 months. Performance status 2 or 3, modified albumin-bilirubin grade 2b or 3, and massive/diffuse type were poor prognostic factors. Nineteen patients (29%) with a treatment effect of 3 or 4 (≥ 50% of tumor necrosis or regression) at the irradiation sites according to the Response Evaluation Criteria in Cancer of the Liver showed longer survival than those with an effect of 1 or 2 (MST 18.7 vs. 5.9 months, p<0.001). No treatment-related death occurred. The hepatic function reserve was preserved in more than 70% of patients. 3D-CRT controlled HCC MVI safely and was suggested to be a good treatment option. |

| Abstract | Patients found to have presumed germline pathogenic variants (PGPVs) during comprehensive genomic profiling (CGP) require genetic counseling (GC) referrals. We retrospectively investigated the outcomes of patients with PGPVs. Among 159 patients who underwent CGP, we recommended GC for the 16 patients with PGPVs (3 with [FG group] and 13 without [G Group] a family/personal history of hereditary cancer) as well as for the 8 patients with no PGPVs, but a history (F group); 2 (67%), 5 (38%), and 3 (38%) patients received GC in the FG, G, and F groups, respectively. Germline testing results were positive in 1 and 2 patients of the FG and G groups, respectively. Among the patients recommended for GC, 58% did not receive GC due to lack of interest, poor performance status, or death. CGP contributes to the identification of germline variants in patients without a history of hereditary cancer. However, the proportion of patients who undergo GC should be improved. |

| Abstract | Maintaining perioperative normothermia decreases the post-surgery surgical site infection (SSI) rate. We investigated whether SSI is associated with intraoperative hypothermia in total hip (THA) and total knee (TKA) arthroplasties by retrospectively analyzing 297 THA and TKA cases. The patients’ intraoperative core body temperature (BT) was measured by bladder catheter or forehead sensor. We evaluated the associations between SSI and intraoperative BT and other variables and patient characteristics. Fifty-six patients (18.8%) had hypothermia (BT <36°C); 43 developed SSI (14.5%); only five had hypothermia (11.6%). Intraoperative hypothermia and SSI were not significantly associated. The SSI group had more men (34.9% vs. 18.1%) and THA patients (77.4%), a longer mean surgical duration (174.3 vs. 143.5 mins), and a higher average BT (36.4°C vs. 36.2°C) than the no-SSI group. The SSI patients had a higher intraoperative BT. A multivariable analysis revealed that SSI was associated with male sex (OR 2.3, 95%CI: 1.031-4.921, p=0.042), longer surgery (OR, 1.01, 95%CI: 1.003-1.017, p=0.004), THA (OR 3.6, 95%CI: 1.258-10.085, p=0.017), and intraoperative BT >36.0°C (OR 3.6, 95%CI: 1.367-9.475, p=0.009). Intraoperative hypothermia was not associated with SSI in adults who underwent THA or TKA. These results suggest that hypothermia might not be the problem for SSI. |

| Abstract | We used biomathematics to describe and compare cerebellar growth in normally developing and trisomy 18 Japanese fetuses. This retrospective study included 407 singleton pregnancies with fetuses at 14-39 weeks of gestation and 33 fetuses with trisomy 18 at 17-35 weeks. We used ultrasonography to measure fetal transverse cerebellar diameter (TCD) and anteroposterior cerebellar diameter (APCD). We hypothesized that cerebellar growth is proportional to cerebellar length at any given time point. We determined the formula L(t) ≒Keat+r, where e is Napier’s number, t is time, L is cerebellar length, and a, K, and r are constants. We then obtained regression functions for each TCD and APCD in all fetuses. The regression equations for TCD and APCD values in normal fetuses, expressed as exponential functions, were TCD(t)=27.85e0.02788t−28.62 (mm) (adjusted R2=0.997), and APCD(t)=324.29e0.00286t−322.62 (mm) (adjusted R2=0.995). These functions indicated that TCD and APCD grew at constant rates of 2.788%/week and 0.286%/week, respectively, throughout gestation. TCD (0.0153%/week) and APCD (0.000430%/week) grew more slowly in trisomy 18 fetuses. This study demonstrates the potential of biomathematics in clinical research and may aid in biological understanding of fetal cerebellar growth. |

The relative miR-338-3p expression in serum was detected by quantitative real-time RT-PCR. Interleukin-1beta (IL-1β), IL-6, and tumor necrosis factor-alpha (TNF-α) levels were detected by ELISAs. A receiver operating characteristic (ROC) curve analysis of serum miR-338-3p evaluated the diagnosis of miR-338-3p in neonatal ARDS. Pearson’s correlation analysis evaluated the correlation between serum miR-338-3p and neonatal ARDS clinical factors. Flow cytometry evaluated apoptosis, and a CCK-8 assay assessed cell viability. A luciferase assay evaluated the miR-338-3p/AKT3 relationship. The miR- 338-3p expression was decreased in neonatal ARDS patients and in lipopolysaccharide (LPS)-treated cells. The ROC curve showed the accuracy of miR-338-3p for evaluating neonatal ARDS patients. The correlation analysis demonstrated that miR-338-3p was related to PRISM-III, PaO2/FiO2, oxygenation index, IL-1β, IL-6, and TNF-α in neonatal ARDS patients. MiR-338-3p overexpression inhibited the secretion of inflammatory components, stifled cell apoptosis, and LPS-induced advanced cell viability. The double-luciferase reporter gene experiment confirmed that miR-338-3p negatively regulates AKT3 mRNA expression. Serum miR-338-3p levels were related to the diagnosis and severity of neonatal ARDS, which may be attributed to its regulatory effect on inflammatory response in ARDS. |

| Abstract | This investigation aimed to uncover the impact of a long noncoding RNA, SET-binding factor 2 antisense RNA1 (SBF2-AS1) on the malignant progression of gastric cancer (GC) and to further explore its underlying mechanism. SBF2-AS1 expression was quantified by qRT-PCR in GC cell lines and GC tissues. In vitro loss-of-function studies of SBF2-AS1, accompanied by flow cytometry, CCK-8, and cell invasion tests, were applied to elucidate the impact of SBF2-AS1 on the tumor progression of GC cells. Finally, Western blotting and a luciferase assay were used to detect WNT/LRP5 signaling pathway activation. SBF2-AS1 was aberrantly expressed in GC cell lines (p<0.05) and GC tissues (p<0.05). Cell invasive and proliferative capabilities were inhibited via SBF2-AS1 knockdown, resulting in apoptosis of NCI-N87 and MKN74 cells. Additionally, online database analysis uncovered a positive correlation between SBF2-AS1 and the Wnt/LRP5 signaling pathway (p<0.05). SBF2-AS1 knockdown blocked the Wnt/LRP5 signaling pathway, whereas the effects of SBF2-AS1 knockdown on the malignant genotype of MKN74 as well as NCI-N87 cells were partially restored by triggering the Wnt/ LRP5 signaling pathway. High expression of SBF2-AS1 was found in GC, the malignant progression of which was repressed via SBF2-AS1 knockdown by inhibiting the Wnt/LRP5 signaling pathway. |

| Abstract | We developed an artificial intelligence (AI) technique to identify epileptic discharges (spikes) in pediatric scalp electroencephalograms (EEGs). We built a convolutional neural network (CNN) model to automatically classify steep potential images into spikes and background activity. For the CNN model’ training and validation, we examined 100 children with spikes in EEGs and another 100 without spikes. A different group of 20 children with spikes and 20 without spikes were the actual test subjects. All subjects were ≥ 3 to < 18 years old. The accuracy, sensitivity, and specificity of the analysis were >0.97 when referential and combination EEG montages were used, and < 0.97 with a bipolar montage. The correct classification of background activity in individual patients was significantly better with a referential montage than with a bipolar montage (p=0.0107). Receiver operating characteristic curves yielded an area under the curve > 0.99, indicating high performance of the classification method. EEG patterns that interfered with correct classification included vertex sharp transients, sleep spindles, alpha rhythm, and low-amplitude ill-formed spikes in a run. Our results demonstrate that AI is a promising tool for automatically interpreting pediatric EEGs. Some avenues for improving the technique were also indicated by our findings. |

| Abstract | Gender affirming surgery (GAS) has important impacts for people with gender incongruence (GI), both physically and socially. As the societal acceptance of gender diversity spreads, the number of individuals with GI who wish to be identified as the gender of their choice is increasing. Indeed, many elderly people who have lived a long time with GI now wish to undergo GAS, but face greater surgical risks due to greater burdens of underlying medical conditions. Generally, vaginoplasty is performed for transwomen; however, this surgery is time-consuming and involves heavy bleeding, and thus, should be avoided in elderly people. A less invasive technique is needed. In this article, we describe a new, less invasive genital feminizing surgical technique for transwomen with reports from two clinical cases. We present this novel technique as a safe, aesthetic, and cost-effective option for gender-affirming surgery for transwomen. |

| Abstract | Pulmonary metastatic resection is a standard therapy for renal cell carcinoma (RCC). Although patients with pulmonary metastases who do not undergo any treatment have poor prognoses, it has been reported that resection for pulmonary metastases yields good clinical outcomes. We investigated the prognoses of the 10 Japanese patients (eight males, two females) who underwent a surgical resection of pulmonary metastasectomy from RCC at our institution between April 1, 2012 and March 31, 2020 and analyzed the prognostic factors. We determined the prognoses and calculated the 5-year overall survival (OS) and disease-free survival (DFS) rates. To identify prognostic factors, we compared the median DFS duration for each factor. Elderly patients (median age, 75.5 years) were more predominant compared to previous studies, and all 10 patients underwent a complete resection. The 5-year DFS rate was 30.5% (95%CI: 0.045-0.63) and the 5-year OS rate was 80% (95%CI: 0.20-0.97). The following factors were associated with better prognosis: female, disease-free interval≥36 months, and metastases size<12 mm. These results indicate that complete resection for pulmonary metastases from RCC resulted in good clinical outcomes, particularly for patients with better prognostic factors. |

| Abstract | The prevalence of preoperative deep vein thrombosis (DVT) has been reported to be relatively high in patients undergoing total hip arthroplasty. We investigated the prevalence of DVT, the association between hip function and preoperative DVT, and the effect of a history of surgery in patients who underwent primary total hip arthroplasty. We retrospectively analyzed the cases of the patients who underwent primary total hip arthroplasty between April 2013 and February 2020 at our institution. We evaluated the prevalence of preoperative DVT based on the results of the patients’ ultrasound screening. We performed univariate and multivariate analyses to investigate the association between the incidence of DVT and patient factors including age, sex, hip function, medical histories, and American Society of Anesthesiologists Physical Status classification. We analyzed 451 patients (494 hips). The prevalence of DVT was 14.2% (64 patients). The multivariate analysis demonstrated that increased age was an independent significant risk factor for DVT. The prevalence of preoperative DVT was relatively high among patients who underwent primary total hip arthroplasty. Preoperative DVT tended to be more prevalent in older patients. Hip function was not associated with the incidence of DVT. |
