| Abstract | To examine the outcome of gestational blood pressure and birth weight in women with normal pre-pregnancy BMI (18.5-25 kg/m2) who are at the lower and upper limits of this range, i.e., slightly underweight or slightly overweight. Overall, 2,038 Japanese women with low -risk who had delivered during January 2014–December 2016 were classified according to their pre-pregnancy BMI: underweight (< 18.5 kg/m2), slightly underweight (18.5≤BMI<21 kg/m2), normal (21≤BMI<23 kg/m2), slightly overweight (23≤BMI<25 kg/m2) and overweight (≤ 25 kg/m2). Their blood pressure during each trimester and birth weight was evaluated. The slightly overweight group showed a significantly higher blood pressure than the underweight and slightly underweight groups. Birth weight was lower in the slightly underweight than in the slightly overweight group (p<0.01). The incidence rate of “heavy for dates” (HFD) infants was significantly higher in the slightly overweight and overweight groups than in the other groups (p<0.05 and p<0.01, respectively). Weight gain of < 7 kg significantly increased the rate of “light for dates” (LFD) infants, while a weight gain of ≥13 kg significantly increased the rate of HFD infants (p<0.05 and p<0.01, respectively). Blood pressure during pregnancy was ssociated with pre-pregnancy BMI. The birth weight of infants of low-risk pregnant women is affected by both pre-pregnancy BMI and gestational weight gain. |

| Abstract | Iterative reconstruction (IR) improves image quality compared with filtered back projection (FBP). This study investigated the usefulness of model-based IR (forward-projected model-based iterative reconstruction solution [FIRST]) in comparison with FBP and hybrid IR (adaptive iterative dose reduction three-dimensional processing [AIDR 3D]) in low-dose paranasal CT. Twenty-four patients with paranasal sinusitis who underwent standard-dose CT (120 kV) and low-dose CT (100 kV) scanning before and after medical treatment were enrolled. Standard-dose CT scans were reconstructed with FBP (FBP120), and low-dose CT scans with FBP (FBP100), AIDR 3D, and FIRST. The signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) in three anatomical structures and effective doses were compared using Mann–Whitney U test. Two radiologists independently evaluated the visibility of 16 anatomical structures, overall image quality, and artifacts. Effective doses in lowdose CT were significantly reduced compared with those in standard-dose CT (0.24 vs 0.43 mSv, p<0.001). FIRST achieved significantly higher SNR (p<0.01, respectively) and CNR (p<0.001, respectively) of evaluated structures and significant improvement in overall image quality (p<0.001), artifacts (p<0.001), and visibility related to muscles (p<0.05) compared to FBP120, FBP100, and AIDR 3D. FIRST allowed radiation-dose reduction, while maintaining objective and subjective image quality in low-dose paranasal CT. |

| Abstract | Eukaryotic genomes contain numerous copies of endogenous viral elements (EVEs), most of which are considered endogenous retrovirus (ERV) sequences. Over the past decade, non-retroviral endogenous viral elements (nrEVEs) derived from ancient RNA viruses have been discovered. Several functions have been proposed for these elements, including antiviral defense. This review summarizes the current understanding of nrEVEs derived from RNA viruses, particularly endogenous bornavirus-like elements (EBLs) and endogenous filovirus-like elements (EFLs). EBLs are one of the most extensively studied nrEVEs. The EBL derived from bornavirus nucleoprotein (EBLN) is thought to function as a non-coding RNA or protein that regulates host gene expression or inhibits virus propagation. Ebolavirus and marburgvirus, which are filoviruses, induce severe hemorrhagic fever in humans and nonhuman primates. Although the ecology of filoviruses remains unclear, bats are believed to be potential reservoirs. Based on the knowledge from EBLs, it is postulated that EFLs in the bat genome help to maintain the balance between filovirus infection and the bat’s defense system, which may partially explain why bats act as potential reservoirs. Further research into the functions of nrEVEs could reveal novel antiviral systems and inspire novel antiviral approaches. |

| Abstract | Glioblastoma (GBM) is a fatal primary malignant brain tumor in adults. Despite decades of research, the prognosis for GBM patients is still disappointing. One major reason for the intense therapeutic resistance of GBM is inter- and intra-tumor heterogeneity. GBM-intrinsic transcriptional profiling has suggested the presence of at least three subtypes of GBM: the proneural, classic, and mesenchymal subtypes. The mesenchymal subtype is the most aggressive, and patients with the mesenchymal subtype of primary and recurrent tumors tend to have a worse prognosis compared with patients with the other subtypes. Furthermore, GBM can shift from other subtypes to the mesenchymal subtype over the course of disease progression or recurrence. This phenotypic transition is driven by diverse tumor-intrinsic molecular mechanisms or microenvironmental factors. Thus, better understanding of the plastic nature of mesenchymal transition in GBM is pivotal to developing new therapeutic strategies. In this review, we provide a comprehensive overview of the current understanding of the elements involved in the mesenchymal transition of GBM and discuss future perspectives. |

| Abstract | Aspergillosis is an infection caused by Aspergillus species, and it manifests in various clinical presentations. We describe the case of a 73-year-old man with a small area of thickening on the thoracic wall detected by computed tomography. Surgical resection confirmed the diagnosis of an Aspergillus abscess. We report this case in view of the rarity of Aspergillus abscess localized to a parietal pleura without any signs of lung parenchymal involvement. After a thorough literature review, we consider this could be the first report of this manifestation. Accumulation of similar cases will be necessary to help spread recognition of this condition. |

| Abstract | A hereditary breast and ovarian cancer (HBOC) pedigree was detected via liquid biopsy, and cancer prevention was initiated for the patient’s daughter, after receiving a definitive result from BRCA genetic testing. A 48-yearold woman with ovarian cancer was administered precision medicine, which used cell-free DNA from plasma. The results revealed a pathogenic variant of BRCA1 as a presumed germline pathogenic mutation. We confirmed the germline pathological variant BRCA1 c.81-1G> A and suggested treatment with a PARP inhibitor. One of her three children had the variant, was diagnosed as an unaffected pathogenic variant carrier, and was advised to initiate surveillance. |

| Abstract | Glioneuronal tumor with neuropil-like islands (GNTNI) is a very rare subtype of glioneuronal tumor. We present a case of a 62-year-old man with GNTNI. Two adjacent lesions in the left parietal lobe were removed by left parietal craniotomy. The histological findings were glial cell proliferation and scattered rosettes consisting of synaptophysin-positive and NeuN-positive cells, leading to the diagnosis of GNTNI. Target sequencing revealed a genetic alteration similar to glioblastoma, IDH-wild type, which suggested adjuvant therapies. There are few previous reports on the treatment of this disease, and the patient should be followed carefully. |

| Abstract | We aimed to identify the role of first-line monotherapy with vascular endothelial growth factor receptor tyrosine kinase inhibitors (VEGFR-TKI) in patients with metastatic RCC. Eligible patients were categorized into three groups (favorable, intermediate, and poor risk) according to the International Metastatic RCC Database Consortium risk criteria. Overall survival (OS) was the primary endpoint. Survival was compared using the log-rank test. A total of 108 patients were retrospectively analyzed. The numbers of patients in the favorable-, intermediate-, and poor-risk groups were 32 (30%), 66 (61%), and 10 (9%), repestively. The median OS values in the entire cohort was 36 months (95% confidence interval [CI] 29-53). The median OS in the favorable, intermediate, and poor risk groups were 94 months (95% CI: 43-Not reached), 30 months (95% CI: 20-38), and 8 months (95% CI: 0-Not reached), respectively (p<0.05). Prior nephrectomy, clear cell histology, clinical T stage ≤2, no metastasis at the time of diagnosis, nivolumab beyond first-line therapy, and objective response to VEGFR-TKIs were factors significantly prolonging OS on univariate analysis. VEGFR-TKI monotherapy as first-line therapy was an effective treatment option for patients with metastatic clear cell RCC with favorable risk. |

| Abstract | To clarify the preventive effects of 0.01% atropine eye drops against myopia progression and axial elongation in children, a meta-analysis was carried out based on data obtained from PubMed and Web of Science as of August 1, 2021. Randomized controlled trials (RCTs) that enrolled myopic children who had received atropine for at least one year were included in this study, Key search terms included myopia, children, and 0.01% or low-dose atropine. Heterogeneity was quantified by I2 statistics, and meta-analyses were performed using the fixed-effect model. Five RCTs involving 809 unique children were analyzed. One trial was excluded because of a poor Jadad score and markedly rapid myopia progression in controls. The mean effect sizes for 12 months in myopia progression and axial elongation synthesized from the remaining 4 RCTs were 0.20 (95% CI: 0.13 to 0.27) D and −0.08 (−0.11 to −0.04) mm, respectively (p<0.0001). The corresponding inhibition ratios were 28% and 19%. I2 statistics were 6% or less. Sensitivity analysis and funnel plots demonstrated the robustness of the estimation. The 0.01% atropine-induced inhibition ratio for myopia progression in Asian children was roughly half of that originally reported and did not reach the minimum requirement for clinical treatment. |

| Abstract | The erythrocyte sedimentation rate (ESR) is a widely used marker of inflammation, but the detailed mechanisms underlying the ESR remain unclear. We retrospectively collected laboratory data from our hospital’s laboratory information system, and performed multiple linear regression analysis and correlation analysis to determine relationships between the ESR and other laboratory test parameters. The alpha-2, beta-2, and gamma fractions from serum protein electrophoresis, serum immunoglobulin (Ig) G, IgA, IgM, and complement C3 levels, plasma fibrinogen levels, and platelet count showed positive effects on the ESR; however, the serum albumin level showed negative effects. Since erythrocytes are negatively charged, an increase in positively charged proteins and a decrease in negatively charged albumin were suggested to increase the ESR. Notably, C-reactive protein (CRP) showed the third-strongest correlation with the ESR despite having no significant effect on the ESR. We also reviewed cases with discordant ESR and CRP levels to compare the disease profiles of high ESR/low CRP patients and low ESR/high CRP patients. The patients with high ESR/low CRP had a completely different disease profile from those with low ESR/high CRP. Since the ESR and CRP have different roles, they should be used as markers in a context-dependent manner. |

| Abstract | This study examined the relationship between cognitive/structural social capital and post-traumatic stress disorder (PTSD) among victims of heavy rain and flood. Participants were individuals aged≥18 years affected by the July 2018 heavy rainfall in the cities of Kurashiki and Soja, Japan, and living in temporary housing. We distributed five copies of a questionnaire to 1,991 households and received responses from 1,927 individuals (907 men, 1,008 women, 12 respondents of unspecified sex) in 1,029 households (51.7%). We estimated odds ratios (ORs) and 95% confidence intervals (CIs) for associations between high (vs. low) social capital and PTSD or other outcomes. After covariate adjustment, the odds of having PTSD were lower in participants with high cognitive social capital than those with low cognitive social capital (OR=0.346, 95%CI: 0.263-0.456). Elderly women with higher structural social capital tended to have lower PTSD odds than those with lower structural social capital (OR=0.671, 95%CI: 0.431-1.046). The opposite pattern was observed for elderly men (OR=1.315, 95%CI: 0.792-2.183). Cognitive social capital is a protective factor that may reduce PTSD or promote a favorable PTSD prognosis after heavy rainfall and flood events. The associations between structural social capital and PTSD differ by age and sex. |

| Abstract | Blood pressure (BP) often rises before surgery. This study investigated whether BP elevation immediately before surgery was associated with adverse outcomes. Medical records of 11,732 patients (average age: 61 years; male: 47.4%) who underwent non-cardiac elective inpatient surgery under general anesthesia at Kagawa University Hospital between January 2011 and June 2019 were reviewed. Differences between the first BP values measured on the day before surgery and the first BP values in the operating room were defined as Δ systolic BP (ΔSBP) and Δ diastolic BP (ΔDBP). The relationships between ΔSBP/ΔDBP and 30-day mortality, 30-day readmission, and over-the-standard length of hospital stay (OSLOS) were assessed. OSLOS was defined as a hospital stay longer than mean+2 standard deviations and was calculated using the Japanese Diagnosis Procedure Combination data. In univariate analysis, the differences in ΔSBP and ΔDBP between the OSLOS and standard LOS groups were both 2 mmHg. In multivariate logistic regression analysis, only ΔDBP was associated with OSLOS. The adjusted odds ratio (95% confidence interval) for the largest quartile was 1.31 (1.02-1.69) (p<0.05). ΔDBP was associated with OSLOS; however, there may be little need to worry about large ΔSBPs and ΔDBPs in clinical practice. |

| Abstract | We compared the effects of an exercise intervention with that of exercise combined with nutrition therapy in patients with possible malnutrition and sarcopenia admitted to a recovery rehabilitation ward, and we examined the differences in the patients’ physical function and activities of daily living (ADLs). There were 16 patients in the Exercise group with exercise therapy and ADL exercises, and 14 patients in the Combined intervention group with exercise therapy, ADL exercises, and nutrition therapy. The survey items were body weight, body mass index, grip strength, lower-leg circumference, gait speed, and ADLs, each of which was measured at the baseline and at 2 weeks, 4 weeks, and at discharge. Significant improvements in grip strength were observed in the Combined intervention group as follows: at 4 weeks>at 2 weeks (p<0.05), and at discharge>baseline and 2 weeks (p<0.05). There were no significant changes in the Exercise group, and an interaction was recognized in both groups. Comprehensive rehabilitation including nutrition therapy is necessary for patients with possible malnutrition and/or sarcopenia, as our results indicate that nutrition therapy in addition to exercise therapy has the effect of promoting improvements of physical function in such patients. |

| Abstract | Posterior capsule opacification (PCO) is a post-surgery complication of cataract surgery, and lens epithelial cells (LECs) are involved in its development. A suppressive effect on LECs is exerted by the non specific chloride channel inhibitor 5-nitro-2-(3-phenylpropylamino) benzoic acid (NPPB) exerts. Herein, the growth and migration inhibitory effects of NPPB on LECs were assessed, and the mechanism underlying the effects were investigated by focusing on Ca2+/CaMKII signaling. LECs were treated with different concentrations of NPPB, and the changes in cell viability, cell-cycle distribution, anchorage-dependent growth, migration, Ca2+ level, and CaMKII expression were evaluated. NPPB inhibited LECs’ proliferation and induced G1 cell-cycle arrest in the cells. Regarding LECs’ mobility, NPPB suppressed the cells’ anchorage-dependent growth ability and inhibited their migration. Changes in cell phenotypes were associated with an increased intracellular Ca2+ level and down-regulation of CaMKII. Together these results confirmed the inhibitory effect of NPPB on the proliferation and migration of LECs, and the effect was shown to be associated with the induced level of Ca2+ and the inhibition of CaMKII signaling transduction. |

| Abstract | We assessed risk factors for postoperative urinary retention (UR) in elderly males with femoral bone fractures: 169 Japanese males (mean age 81.95 ± 1.19 years) who had undergone hip surgery at a municipal hospital (Toyama, Japan). A multiple logistic regression analysis was used to test possible risk factors for UR: age, body mass index, serum albumin, cognitive impairment, activities of daily living (ADL), and history of diabetes mellitus (DM). UR occurred in 24 (14.2%) of the 169 patients. A multivariate logistic regression analysis with age adjustment showed that ADL (odds ratio [OR] 3.88; 95% confidence interval [CI]: 1.2-12.5, p=0.023) was significantly associated with the development of UR, and a history of DM showed marginal significance for UR occurrence (OR 0.36, 95%CI: 0.11-10, p=0.064). These results suggests that ADL is a risk factor for UR development in elderly males who have undergone surgery for femoral neck or trochanter fractures. |

| Abstract | According to a recent report, a low Ki67 level after short-term preoperative hormone therapy (post-Ki67) might suggest a more favorable prognosis compared with a high post-Ki67 level in patients with hormone receptorpositive/human epidermal growth factor 2-negative (HR+/HER2−) breast cancer with high levels of Ki67. This study aimed to evaluate the pre-treatment genetic differences between these two patient groups. Forty-five luminal B-like patients were stratified into two groups, namely, a group with high (H→H) and one with low (H→L) Ki67 levels after short-term preoperative aromatase inhibitor (AI) treatment. We compared pre-treatmentgene expression profiles between the two groups. In gene level analysis, there was no significant difference between the two groups by the class comparison test. In pathway analysis, five metabolism-related gene sets were significantly upregulated in the H→L group (p≤0.05). In the search for novel targets, five genes (PARP, BRCA2, FLT4, CDK6, and PDCD1LG2) showed significantly higher expression in the H→H group (p≤0.05). Several metabolism-related pathways were associated with sensitivity to AI. In the future, it will be necessary to seek out new therapeutic strategies for the poor prognostic group with high post-Ki67. |

| Abstract | Tanden breathing, an ancient health technique, involves expiratory abdominal pressure breathing is practiced in Japan. In this study we examined the ability of Tanden breathing to relieve constipation. The study was designed as a stratified-block randomized controlled trial enrolling 20 participants. Nineteen were female and one was male, none were elderly. During the 6-week intervention period, the participants performed video-guided Tanden breathing about 10 min once day. We evaluated constipation using the Constipation Assessment Scale (CAS). There were significant differences in the mean CAS score between time points (baseline, 3 weeks after baseline, 6 weeks after baseline), groups (intervention and control), and their interaction (time×group) using repeated-measures analysis of variance. The control group showed no change in the mean CAS score; the mean CAS scores of the intervention group changed from 7.2 at baseline to 3.9 at 3 weeks and 3.1 at 6 weeks after baseline. A regression analysis of the difference in the mean CAS between baseline and 6 weeks later showed that the CAS of the intervention group was 4.3 points lower than that of the control group (95% confidence interval, 2.5-6.1). The results suggested that Tanden breathing is effective in relieving constipation among young women. |

| Abstract | The relationship between perioperative clinical course variables and postoperative length of hospital stay (LOS) in patients undergoing primary intracranial meningioma resection has not been fully elucidated. We therefore aimed to identify the perioperative clinical course variables that predict postoperative LOS in such patients. We retrospectively collected data concerning demographics, tumor characteristics, and perioperative clinical course variables in 76 patients who underwent primary intracranial meningioma resection between January 2010 and December 2019, and tested for associations with postoperative LOS. Univariate analyses showed that younger age, fewer days to postoperative initiation of standing/walking, preoperative independence in activities of daily living (ADL), and ADL independence one week after surgery were associated with shorter postoperative LOS. Multiple regression analyses with these factors identified that days to stand/walk initiation and ADL independence one week after surgery were associated with postoperative LOS. Based on these results, we conclude that rehabilitation programs that promote early mobilization and the early acquisition of independence may reduce postoperative LOS in patients who undergo primary intracranial meningioma resection. |

| Abstract | Parkinson’s disease (PD) is a progressive neurodegenerative disease of both the central and peripheral / enteric nervous systems. Oxidative stress and neuroinflammation are associated with the pathogenesis of PD, suggesting that anti-oxidative and anti-inflammatory compounds could be neuroprotective agents for PD. Eucommia ulmoides (EU) is a traditional herbal medicine which exerts neuroprotective effects by anti-inflammatory and anti-oxidative properties. Our previous study showed that treatment with chlorogenic acid, a component of EU, protected against neurodegeneration in the central and enteric nervous systems in a PD model. In this study, we examined the effects of EU extract (EUE) administration on dopaminergic neurodegeneration, glial response and α-synuclein expression in the substantia nigra pars compacta (SNpc), and intestinal enteric neurodegeneration in low-dose rotenone-induced PD model mice. Daily oral administration of EUE ameliorated dopaminergic neurodegeneration and α-synuclein accumulation in the SNpc. EUE treatment inhibited rotenone- induced decreases in the number of total astrocytes and in those expressing the antioxidant molecule metallothionein. EUE also prevented rotenone-induced microglial activation. Furthermore, EUE treatment exerted protective effects against intestinal neuronal loss in the PD model. These results suggest that EU exerts neuroprotective effects in the central and enteric nervous systems of rotenone-induced parkinsonism mice, in part by glial modification. |

| Abstract | Systemic lupus erythematosus (SLE) is a potentially fatal systemic autoimmune disease, and its etiology involves both genetic and environmental factors such as sex hormone imbalance, genetic predisposition, epigenetic regulation, and immunological factors. Dysregulation of microRNA (miRNA) is suggested to be one of the epigenetic factors in SLE. miRNA is a 22-nucleotide single-stranded noncoding RNA that contributes to post-transcriptional modulation of gene expression. miRNA targeting therapy has been suggested to be useful for the treatment of cancers and other diseases. Gene knockout and miRNA targeting therapy have been demonstrated to improve SLE disease activity in mice. However, these approaches have not yet reached the level of clinical application. miRNA targeting therapy is limited by the fact that each miRNA has multiple targets. In addition, the expression of certain miRNAs may differ among cell tissues within a single SLE patient. This limitation can be overcome by targeted delivery and chemical modifications. In the future, further research into miRNA chemical modifications and delivery systems will help us develop novel therapeutic agents for SLE. |
