Abstract
Treatment of edentulous and atrophic mandibular fractures is extremely difficult. Generally, mandibular fractures are repaired and fixed as internal fixation using a reconstruction plate or miniplates with intra- or extraoral approach. Few cases in which external fixation including a transmucosal fixation was performed have also been reported. We report a case of atrophic and edentulous mandibular fracture which was healed by the fixation using dental implants and implant-supported bridge.

Abstract
BACKGROUND Whether nerve block improves the quality of conscious sedation (CS) in patients undergoing transcatheter aortic valve implantation (TAVI) is unclear. This study investigated whether fascia iliaca block (FIB) reduced the remifentanil requirement and relieved pain in CS for TAVI.Methods and Results: This prospective study randomized 72 patients scheduled for elective TAVI under CS into 2 groups, with (FIB) and without (control) FIB (n=36 in each group). The sedation targeted a Bispectral Index <90 with a Richmond Agitation-Sedation Scale of -2 to -1. Dexmedetomidine (0.7 µg/kg, i.v.) combined with remifentanil (0.03 µg/kg/min, i.v.) and propofol (0.3 mg/kg/h, i.v.) was used to commence sedation. FIB using 30 mL of 0.185% ropivacaine was implemented 2 min before TAVI. Patient sedation was maintained with dexmedetomidine (0.4 µg/kg/h, i.v.) supplemented with remifentanil (0-0.02 µg/kg/min, i.v.). Remifentanil (20 µg, i.v.) was used as a rescue dose for intraprocedural pain. Compared with the control group, FIB reduced the both the total (median [interquartile range] 83.0 [65.0-98.0] vs. 34.5 [26.0/45.8)] µg; P<0.001) and continuous (25.3 [20.9/31.5] vs. 9.5 [6.8/12.5] ng/kg/min; P<0.001) doses of remifentanil administered. CONCLUSIONS FIB reduced the remifentanil requirement and relieved pain in patients undergoing TAVI with CS. Therefore, FIB improved the quality of CS in TAVI.

Abstract
Background Mechanistic insight into the high failure rate of TOF-Cuff® (RGB Medical Devices, Madrid, Spain) measurements on the lower leg is unclear. Aims We aimed to determine whether materials applied to pseudo-skin can reduce the impedance between a model arm and TOF-Cuff® electrodes and whether a material between TOF-Cuff® electrodes and the patient's skin surface decreases the skin-TOF-Cuff® electrode impedance within the appropriate range. Methods This was a combination of an in vitro study using non-living materials and a prospective observational clinical study. Eight patients aged > 70 years who had undergone elective surgery were eligible. One of the primary outcomes was whether water, electrocardiogram (ECG) cream, or ECG gel applied on the pseudo-skin could reduce the impedance between the model arm and the TOF-Cuff® electrodes in the in vitro study. Another was whether a material between the TOF-Cuff® electrodes and the patient's skin surface decreased the skin-TOF-Cuff® electrode impedance to an appropriate level of less than 5,000 Ω in the clinical study. Results The application of water, ECG cream, and ECG gel similarly reduced the impedance values within the electrical circuit in the in vitro study. ECG cream application between the patient's skin surface and the TOF-Cuff® electrodes decreased the skin-TOF-Cuff® electrode impedance (median (interquartile range (IQR)) Ω) from 8,600 (6,450 to 9,775) to 2,000 (1,600 to 2,600) (P = 0.012) in surgical patients. Conclusion ECG cream application between the patient's skin surface and the TOF-Cuff® electrodes decreased the skin-TOF-Cuff® electrode impedance appropriately, and thus, the application can facilitate precise TOF-Cuff® measurements in patients.

Abstract
OBJECTIVE Automated cuff blood pressure (BP) devices are widely used for ambulatory, home, and office BP measurement. However, an automated device, which is accurate in the general adult population may be inaccurate in some special populations. A 2018 Collaborative Statement by the US Association for the Advancement of Medical Instrumentation, the European Society of Hypertension, and the International Organization for Standardization (ISO) considered three special populations requiring separate validation (age <3 years, pregnancy, and atrial fibrillation). An ISO Task Group was appointed to identify evidence for additional special populations. METHOD Evidence on potential special populations was identified from the STRIDE BP database, which performs systematic PubMed searches for published validation studies of automated cuff BP monitors. Devices that passed in a general population, but failed in potential special populations were identified. RESULTS Of 338 publications (549 validations, 348 devices) in the STRIDE BP database, 29 publications (38 validations, 25 devices) involved 4 potential special populations: (i) age 12-18 years: 3 of 7 devices failed but passed in a general population; (ii) age more than 65 years: 1 of 11 devices failed but passed in a general population; (iii) diabetes type-2: 4 devices (all passed); (iv) chronic kidney disease: 2 of 7 devices failed but passed in a general population. CONCLUSION Some evidence suggest that the automated cuff BP devices may have different accuracy in adolescents and in patients with chronic kidney disease than in the general population. More research is needed to confirm these findings and investigate other potential special populations.

Abstract
A male patient was scheduled for urgent amputation of his right forearm. His right forearm was stuck inside the insertion slot of a meat grinder, resulting in severe pain to his injured arm. His upper body could not move to sit in a semi-upright position. An endotracheal tube was successfully placed after rapid sequence intubation using a video laryngoscope from behind the patient on the first attempt. This case report is the first documentation of successful anesthetic induction with subsequent endotracheal intubation using a video laryngoscope from behind an injured patient whose upper body was upright with limited positioning.

Abstract
PURPOSE Postoperative delirium is one of the most common complications after cardiovascular surgery in older adults. Benzodiazepines are a reported risk factor for delirium; however, there are no studies investigating remimazolam, a novel anesthetic agent. Therefore, we prospectively investigated the effect of remimazolam on postoperative delirium. METHODS We included elective cardiovascular surgery patients aged ≥ 65 years at Hamamatsu University Hospital between August 2020 and February 2022. Patients who received general anesthesia with remimazolam were compared with those who received other anesthetics (control group). The primary outcome was delirium within 5 days after surgery. Secondary outcomes were delirium during intensive care unit stay and hospitalization, total duration of delirium, subsyndromal delirium, and differences in the Mini-Mental State Examination scores from preoperative to postoperative days 2 and 5. To adjust for differences in the groups' baseline covariates, we used stabilized inverse probability weighting as the primary analysis and propensity score matching as the sensitivity analysis. RESULTS We enrolled 200 patients; 78 in the remimazolam group and 122 in the control group. After stabilized inverse probability weighting, 30.3% of the remimazolam group patients and 26.6% of the control group patients developed delirium within 5 days (risk difference, 3.8%; 95% confidence interval -11.5% to 19.1%; p = 0.63). The secondary outcomes did not differ significantly between the groups, and the sensitivity analysis results were similar to those for the primary analysis. CONCLUSION Remimazolam was not significantly associated with postoperative delirium when compared with other anesthetic agents.

Abstract
"Akahoya" is a volcanic soil classified as a special soil deposited in Kyushu, Japan. Many of its properties are not yet clearly understood. We found that Akahoya had the potential to adsorb bacteria in cattle feces, which prompted us to investigate its material properties and perform experiments to comprehensively evaluate its adsorption performance for various fine particles such as acidic and basic dyes, NOx/SOx gas, and phosphoric acid ions, in addition to bacteria. Akahoya had a very high specific surface area owing to the large number of nanometer-sized pores in its structure; it exhibited a high adsorption capacity for both NO2 and SO2. Regarding the zeta potential of Akahoya, the point of zero charge was approximately pH 7.0. The surface potential had a significant effect on the adsorption of acidic and basic dyes. Akahoya had a very high cation exchange capacity when the sample surface was negatively charged and a high anion exchange capacity when the sample surface was positively charged. Akahoya also exhibited a relatively high adsorption capacity for phosphoric acid because of its high level of Al2O3, and the immersion liquid had a very high Al ion concentration. Finally, filtration tests were performed on Escherichia coli suspension using a column filled with Akahoya or another volcanic soil sample. The results confirmed that the Escherichia coli adhered on the Akahoya sample. The results of the Escherichia coli release test, after the filtration test, suggested that this adhesion to Akahoya could be phosphorus-mediated.

Abstract
Blood pressure variability (BPV) is an important indicator in risk stratification for hypertension. Among the daily BPVs assessed using a 24-h ambulatory blood pressure (BP) monitor nocturnal systolic BPV has been suggested to predict cardiovascular risks. We hypothesized that very short-term BPV at rest would correlate with nocturnal BPV because of the shared autonomic BP regulatory system under no daily exertion. Thirty untreated normotensive and hypertensive adults underwent 30-min continuous beat-by-beat BP recordings in the supine position, followed by 24-h ambulatory blood pressure monitoring (ABPM). The relationship between very short-term BPV (standard deviation (SD), coefficient of variation (CV)) and daytime and nocturnal BPV (SD, CV, average real variability (ARV), and standardized ARV (CV-ARV)) was assessed with Pearson's correlation coefficients. Very short-term BPV correlated significantly with nocturnal BPV (ARV, r = 0.604, p < 0.001) but not with daytime BPV. These trends were more pronounced with the increasing data length of continuous beat-by-beat BP recording. Using a data segment from the last 10 min of a 30-min continuous beat-by-beat BP recording resulted in a stronger correlation between very short-term BPV and nocturnal BPV than using earlier segments. The findings of this study suggest that very short-term BPV in the supine position at rest may predict nocturnal BPV. Since the burden of ABPM for patients has hindered clinical dissemination, very short-term BPV has the potential to develop a novel index of BPV.

Abstract
Background The population affected by colorectal cancer is growing, and there is an increasing need for prevention of functional decline following treatment. We proposed that the Kihon Checklist published by the Japanese Ministry of Health, Labor, and Welfare would be an appropriate means of frailty assessment for prediction of postoperative complications in older patients with colorectal cancer. This prospective cohort study aims to identify the factors influencing postoperative frailty. Methods We prospectively enrolled consecutive patients with colorectal cancer and aged ≥ 65 year (N = 500) between May 2017 and December 2018. Eligible patients were assessed with the Kihon Checklist prior to surgery and 30 days after surgery. The main measures were variables related to postoperative change in view of frail status. Results According to the Kihon Checklist questionnaire, 164 patients were frail preoperatively and 172 patients were frail postoperatively, whereas 38 patients changed from "nonfrail" before surgery to postoperative "frail." Overall complications were counted in 97 patients (19.4%), and 5 patients died. Performance status ≥ 2, history of laparotomy, open surgery, complication, ostomy creation, and delirium were significantly associated with changing postoperative "frail" (P = .014, P = .023, P = .006, P < .001, P = .023, and P = .024, respectively). In multivariate analysis, independent related factors of changing postoperative "frail" were complication (odds ratio 2.69, 95% confidence interval 1.19–6.09, P = .018) and ostomy creation (odds ratio 2.32, 95% confidence interval 1.01–5.33, P = .047). Conclusion The Kihon Checklist questionnaire could identify the factors related to postoperative change of frailty status in older patients with colorectal cancer. This cohort concluded that whether postoperative complication occurred or not was closely associated with perioperative change of frailty status. Our prospective cohort study examined the factor influencing postoperative frailty in older patients with colorectal cancer by Kihon Checklist questionnaire. The importance of this study is that postoperative complication and ostomy creation were significantly associated with postoperative change of frailty status.

Abstract
Laparoscopic subtotal cholecystectomy, a bailout surgery for cholecystitis, can result in postoperative bile leakage, so surgical ingenuity is required. An 88-year-old woman had pain at the right hypochondrium. Abdominal computed tomography showed swelling of the gallbladder and thickness of the gallbladder wall, leading to diagnosis of mild acute cholecystitis. Percutaneous transhepatic gallbladder drainage was performed to alleviate cholecystitis because the patient was taking antiplatelet medicine. Laparoscopic cholecystectomy was then performed within 72 hours from the onset. The gallbladder was operatively found to be strongly fibrotic, so the procedure was switched to laparoscopic subtotal cystectomy, dissecting the gallbladder at the infundibulum-cystic duct level. The gallbladder stump was closed with barbed suture and omentopexy was added due to fragility. There was no significant postoperative bile leakage. Additional omentopexy to stump closure in laparoscopic subtotal cholecystectomy was thought to be useful in prevention of postoperative bile leakage.

Abstract
To reuse waste glass fiber-reinforced plastics (GFRPs), porous ceramics (i.e., GFRP/clay ceramics) were produced by mixing crushed GFRP with clay followed by firing the resulting mixture under different conditions. The possibility of using ceramics fired under a reducing atmosphere as adsorbent materials to remove NOx and SOx from combustion gases of fossil fuels was investigated because of the high porosity, specific surface area, and contents of glass fibers and plastic carbides of the ceramics. NO2 and SO2 adsorption tests were conducted on several types of GFRP/clay ceramic samples, and the gas concentration reduction rates were compared to those of a clay ceramic and a volcanic pumice with high NO2 adsorption. In addition, to clarify the primary factor affecting gas adsorption, adsorption tests were conducted on the glass fibers in the GFRP and GFRP carbides. The reductively fired GFRP/clay ceramics exhibited high adsorption performance for both NO2 and SO2. The primary factor affecting the NO2 adsorption of the ceramics was the plastic carbide content in the clay structure, while that affecting the SO2 adsorption of the ceramics was the glass fiber content.

Abstract
Multiple-system atrophy is an adult-onset progressive neurodegenerative disease affecting the central nervous system, including the spinal cord. There has been no perioperative guideline of the muscle relaxants used in multiple-system atrophy, although a recent article recommends anesthesiologists to use shorter-acting drugs at the lowest possible doses in the patients. Here, we document the first case with multiple-system atrophy undergoing surgery managed with a combination of rocuronium and sugammadex. The recovery time to the train-of-four count 2 after intravenous rocuronium 0.6 mg / kg, or the time from the start of sugammadex 2 mg / kg intravenously to the train-of-four ratio over 0.9 was prolonged in our case more than 20 and 2 minutes compared with those in healthy subjects, respectively. Neuromuscular monitoring, in addition to the careful vigilance in the perioperative period, seems mandatory in the patients. J. Med. Invest. 68 : 381-382, August, 2021.

Abstract
Serum albumin levels are inversely related with oxidative stress, but positively related with endothelial function, in pregnant women. However, it is unclear whether hypoalbuminemia in pregnant women with preeclampsia (PE) increases the production of oxygen-derived free radicals and impacts endothelial function. The present study aimed to assess the relationship between serum albumin, oxidative stress, and endothelial dysfunction in pregnant women with PE. A total of 75 women with control pregnancy (Control group, n = 30), PE (PE group, n = 24), or gestational hypertension (GH) (GH group, n = 21) were enrolled. We assessed serum albumin levels, diacron-reactive oxygen metabolites (d-ROMs) as an oxygen-derived free radical marker, and flow-mediated dilation (FMD) as a readout for vascular endothelial function during the gestational period and at one month after delivery. During the gestational period, FMD was lower, but d-ROM levels were higher, in the PE and GH groups compared with the Control group. Serum albumin levels were lower in the PE group compared with the Control and GH groups. d-ROM levels were inversely correlated with serum albumin levels (r = -0.54, p < 0.05) and FMD (r = -0.56, p < 0.05) in the PE group, and negatively correlated with FMD, but not serum albumin levels, in the GH group. Serum levels of d-ROMs and albumin, as well as FMD, were similar between groups after delivery. Our findings suggest that reduced serum albumin levels enhance the production of oxygen-derived free radicals, resulting in impaired maternal vascular endothelial function in parturients with PE.

Abstract
Background In adults, high-dose remifentanil during surgery has been reported to increase postoperative opioid consumption, but this has not been well documented in children. Multimodal analgesia is recommended in the perioperative period for adolescent idiopathic scoliosis (AIS), but no report has examined opioid consumption under epidural analgesia, which is one of the most common types of analgesia. Aims To investigate the association between intraoperative remifentanil dosage and postoperative opioid consumption in AIS in the setting of combined epidural analgesia for postoperative multimodal analgesia. Methods In this retrospective cohort study, patients aged 10-18 years who underwent surgery for scoliosis and epidural analgesia for postoperative pain between July 2012 and April 2019 were included. The primary endpoint was the association between intraoperative cumulative weight-adjusted remifentanil dosage and logarithmic transformation of cumulative weight-adjusted fentanyl consumption in the intensive care unit (ICU). Nonopioid analgesics were investigated as secondary endpoints. An epidural catheter was inserted by the surgeon intraoperatively, and a local anesthetic was administered at the end of the surgery. Multivariate linear regression analysis with adjustment for confounders was performed for all analyses. Results In total, 142 patients were included, and the median intraoperative remifentanil dosage for all patients was 0.27 (interquartile range, 0.24-0.34) µg/kg/min. No association was observed between cumulative weight-adjusted intraoperative dosage of remifentanil and fentanyl, even after adjusting for potential confounders (slope = -1.25; 95% confidence interval [CI], -4.35 to 1.85; P = 0.43). No association was observed between nonopioid analgesic use and intraoperative remifentanil dosage. Conclusion No association was noted between remifentanil dosage during surgery for AIS and postoperative opioid consumption with epidural analgesia. However, this study has limitations due to its retrospective design; thus, further prospective studies are warranted.

Abstract
Among reactive oxygen species, superoxide mediates the critical vascular redox signaling, resulting in the regulation of the human cardiovascular system. The reduced form of nicotinamide adenine dinucleotide phosphate oxidase (NADPH oxidase, NOX) is the source of superoxide and relates to the crucial intracellular pathology and physiology of vascular smooth muscle cells, including contraction, proliferation, apoptosis, and inflammatory response. Human vascular smooth muscle cells express NOX1, 2, 4, and 5 in physiological and pathological conditions, and those enzymes play roles in most cardiovascular disorders caused by hypertension, diabetes, inflammation, and arteriosclerosis. Various physiologically active substances, including angiotensin II, stimulate NOX via the cytosolic subunits’ translocation toward the vascular smooth muscle cell membrane. As we have shown, some pathological stimuli such as high glucose augment the enzymatic activity mediated by the phosphatidylinositol 3-kinase-Akt pathway, resulting in the membrane translocation of cytosolic subunits of NOXs. This review highlights and details the roles of human vascular smooth muscle NOXs in the pathophysiology and clinical aspects. The regulation of the enzyme expressed in the vascular smooth muscle cells may lead to the prevention and treatment of human cardiovascular diseases.

Abstract
PURPOSE Stable iodine prophylaxis helps prevent childhood thyroid cancer in nuclear emergencies; however, there is limited information on its effect on thyroid function. This study aimed to examine thyroid function and autoimmunity among children and adolescents that took stable iodine after the Fukushima Nuclear Disaster. METHODS For this observational study, data were obtained from children and adolescents that underwent thyroid cancer screening at Hirata Central Hospital from April 2012 to March 2018. Participant characteristics, including possible hypothyroidism and hyperthyroidism, were compared between the prophylaxis and no-prophylaxis groups. Multivariable logistic regression models were used to assess for possible hypothyroidism, autoantibodies positive, and hyperthyroidism. RESULTS A total of 1,225 participants with stable iodine prophylaxis and 3,946 without prophylaxis were enrolled. Of those participants, blood samples were available for 144 and 1,201 participants in the prophylaxis and no-prophylaxis groups, respectively. There were 17 (11.8%) and 146 cases (12.2%) of possible hypothyroidism or autoantibodies positive cases in the prophylaxis and no-prophylaxis groups, respectively, and there were no cases and 3 cases (0.2%) of possible hyperthyroidism in those two groups, respectively. Multivariable analysis for possible hypothyroidism revealed no association between stable iodine intake and possible hypothyroidism or autoantibodies positive [odds ratio 0.716 (95% confidence interval 0.399-1.284)] (p = 0.262). We did not perform multivariable analysis for hyperthyroidism due to the limited number of cases. CONCLUSION Significant adverse effects of stable iodine intake on thyroid function were not observed among children and adolescents 7 years after the Fukushima Nuclear Disaster.

Abstract
BACKGROUND The increase of blood pressure (BP) variability (BPV) is recognized as an important additional cardiovascular risk factor in both normotensive subjects and hypertensive patients. Aging-induced atherosclerosis and autonomic dysfunction impair the baroreflex and, in turn, augment 24-hour BPV. In small and large animal experiments, impaired baroreflex steepens the slope of the power spectrum density (PSD) of continuous BP in the frequency range of 0.01 to 0.1 Hz. Although the repeated oscillometric BP recording over 24 hours or longer is a prerequisite to quantify BPV in humans, how the very short-term continuous BP recording reflects BPV remains unknown. This study aimed to evaluate the impact of aging on the very short-term (30-min) BPV in healthy human subjects by frequency analysis. METHODS We recorded continuous BP tonometrically for 30 min in 56 healthy subjects aged between 28 and 85 years. Considering the frequency-dependence of the baroreflex dynamic function, we estimated the PSD of BP in the frequency range of 0.01 to 0.1 Hz, and compared the characteristics of PSD among four age groups (26-40, 41-55, 56-70 and 71-85 years). RESULTS Aging did not significantly alter mean and standard deviation (SD) of BP among four age groups. PSD was nearly flat around 0.01 Hz and decreased gradually as the frequency increased. The slope of PSD between 0.01 and 0.1 Hz was steeper in older subjects (71 years or older) than in younger subjects (55 years or younger) (p < 0.05). CONCLUSIONS Aging steepened the slope of PSD of BP between 0.01 and 0.1 Hz. This phenomenon may partly be related to the deterioration of the baroreflex in older subjects. Our proposed method to evaluate very short-term continuous BP recordings may contribute to the stratification of BPV.

Abstract
BACKGROUND Early postoperative small bowel obstruction (EPSBO) is one of the most common complications after colorectal cancer (CRC) surgery, and clarification of its causes is desired. Several reports have demonstrated the risks of EPSBO, but few have focused on laparoscopic surgery for CRC and intraoperative maneuvers. We therefore prospectively examined the risk factors for EPSBO after laparoscopic CRC resection. METHODS We prospectively enrolled 706 patients with CRC that underwent laparoscopic CRC resection in our hospital and affiliated hospitals. We analyzed several factors concerning EPSBO including intraoperative procedures. RESULTS EPSBO developed in 43 of the 706 cases (6.1%). Univariate analysis showed that risk factors for EPSBO were male sex, increased operative time, repositioning of the small intestine before wound closure and anastomotic leakage. Risk factors for EPSBO according to multivariate analysis were increased operative time (odds ratio (OR) 2.41; P = 0.032), repositioning of the small intestine before wound closure (OR 3.58; P = 0.005) and anastomotic leakage (OR 3.91; P = 0.006). CONCLUSION To reduce EPSBO after laparoscopic CRC surgery, the operation should be finished as soon as possible without performing optional maneuvers. To avoid development to EPSBO, particular care is required in cases where the risk of anastomotic leakage is predicted to be high.

Abstract
AIMS/INTRODUCTION The aim of the present study was to clarify the pathophysiologies of hyperglycemic crises in Japanese patients. MATERIALS AND METHODS This was a retrospective study of patients with hyperglycemic crises admitted to Kumamoto Medical Center, Kumamoto, Japan, between 2012 and 2019. Patients were classified as having diabetic ketoacidosis (DKA), hyperglycemic hyperosmotic syndrome (HHS) or a mixed state of the two conditions (MIX), and laboratory data and levels of consciousness at hospital admission, as well as the rates of mortality and coagulation disorders, were compared. RESULTS The diagnostic criteria for hyperglycemic crisis were met in 144 cases, comprising 87 (60.4%), 38 (26.4%) and 19 (13.2%) cases of DKA, HHS and MIX, respectively. Type 1 diabetes was noted in 46.0 and 26.3% of patients in the DKA and MIX groups, respectively. Fibrin degradation product and D-dimer levels were significantly higher in the HHS group than in the DKA group (DKA and HHS groups: fibrin degradation product 7.94 ± 8.43 and 35.54 ± 51.80 μg/mL, respectively, P < 0.01; D-dimer 2.830 ± 2.745 and 14.846 ± 21.430 μg/mL, respectively, P < 0.01). Mortality rates were 5.7, 13.2 and 5.3% in the DKA, HHS and MIX groups, respectively. Seven patients (4.9%), four of whom were in the MIX group, had acute arterial occlusive diseases. CONCLUSIONS The low frequency of type 1 diabetes in DKA and MIX might be responsible for reduced insulin secretion in Japanese populations. Patients with hyperglycemic crises have increased coagulability, and acute arterial occlusion needs to be considered, particularly in MIX.

Abstract
Abstract
Background
In the development of heart failure, pathological intracellular signaling reactivates fetal cardiac genes, which leads to maladaptive remodeling and cardiac dysfunction. We previously reported that a transcriptional repressor, neuron restrictive silencer factor (NRSF) represses fetal cardiac genes and maintains normal cardiac function under normal conditions, while hypertrophic stimuli de-repress this NRSF mediated repression via activation of CaMKII. Molecular mechanisms by which NRSF maintains cardiac systolic function remains to be determined, however.
Purpose
To elucidate how NRSF maintains normal cardiac homeostasis and identify the novel therapeutic targets for heart failure.
Methods and results
We generated cardiac-specific NRSF knockout mice (NRSF cKO), and found that these NRSF cKO showed cardiac dysfunction and premature deaths accompanied with lethal arrhythmias, as was observed in our previously reported cardiac-specific dominant-negative mutant of NRSF transgenic mice (dnNRSF-Tg).
By cDNA microarray analysis of dnNRSF-Tg and NRSF-cKO, we identified that expression of Gnao1 gene encoding Gαo, a member of inhibitory G proteins, was commonly increased in ventricles of both types of mice.
ChIP-seq analysis, reporter assay and electrophoretic mobility shift assay identified that NRSF transcriptionally regulates Gnao1 gene expression.
Genetic Knockdown of Gαo in dnNRSF-Tg and NRSF-cKO by crossing these mice with Gnao1 knockout mice ameliorated the reduced systolic function, increased arrhythmogenicity and reduced survival rates.
Transgenic mice expressing a human GNAO1 in their hearts (GNAO1-Tg) showed progressive cardiac dysfunction with cardiac dilation. Ventricles obtained from GNAO1-Tg have increased phosphorylation level of CaMKII and increased expression level of endogenous mouse Gnao1 gene. These data suggest that increased cardiac expression of Gαo is sufficient to induce pathological Ca2+-dependent signaling and cardiac dysfunction, and that Gαo forms a positive regulatory circuit with CaMKII and NRSF.
Electrophysiological analysis in ventricular myocytes of dnNRSF-Tg revealed that impaired Ca2+ handling via alterations in localized L-type calcium channel (LTCC) activities; decreased T-tubular and increased surface sarcolemmal LTCC activities, underlies Gαo-mediated cardiac dysfunction.
Furthermore, we also identified increased expression of Gαo in ventricles of two different heart failure mice models, mice with transverse aortic constriction and mice carrying a mutant cardiac troponin T, and confirmed that genetic reduction of Gαo prevented the progression of cardiac dysfunction in both types of mice.
Conclusions
Increased expression of Gαo, induced by attenuation of NRSF-mediated repression forms a pathological circuit via activation of CaMKII. This circuit exacerbates cardiac remodeling and progresses heart failure by impairing Ca2+ homeostasis. Gαo is a potential therapeutic target for heart failure.

Abstract
The role of cytoskeleton dynamics in the oxidative stress toward human vasculature has been unclear. The current study examined whether the cytoskeleton-disrupting agent cytochalasin B reduces oxidative stress caused by high glucose in the human arterial smooth muscle. All experiments in the human omental arteries without endothelium or the cultured human coronary artery smooth muscle cells were performed in d-glucose (5.5 mmol/L). The exposure toward d-glucose (20 mmol/L) for 60 min reduced the relaxation or hyperpolarization to an ATP sensitive K+ channel (KATP) opener levcromakalim (10-8 to 3 × 10-6 mol/L and 3 × 10-6 mol/L, respectively). Cytochalasin B and a superoxide inhibitor Tiron, restored them similarly. Cytochalasin B reduced the NADPH oxidase activity, leading to a decrease in superoxide levels of the arteries treated with high d-glucose. Also, cytochalasin B impaired the F-actin constitution and the membrane translocation of an NADPH oxidase subunit p47phox in artery smooth muscle cells treated with high d-glucose. A clinical concentration of cytochalasin B prevented human vascular smooth muscle malfunction via the oxidative stress caused by high glucose. Regulation of the cytoskeleton may be essential to keep the normal vascular function in patients with hyperglycemia.

Abstract
UNLABELLED There is still a lack of evidence that minodronate or denosumab prevents bone loss due to androgen deprivation therapy (ADT) in non-Western patients. This study showed that both drugs significantly improved lumbar spine and total hip bone mineral density in Asian men with prostate cancer who received ADT. INTRODUCTION To evaluate whether monthly oral minodronate or semiannual subcutaneous injection of denosumab improves bone mineral density (BMD) in Asian men with prostate cancer (PCa) receiving ADT. METHODS A multicenter, open-label, randomized, controlled study including patients with hormone-sensitive PCa without bone metastasis receiving ADT was performed. Patients were randomized (1:1:1) to minodronate, denosumab, or no agent control groups. The primary end point was the mean percentage change in BMD at the lumbar spine at 12 months. Secondary end points were the mean percentage change in BMD at the femoral neck and total hip and changes in bone turnover markers. Statistical comparison was performed using analysis of covariance. RESULTS Of the 147 subjects enrolled in this study, 102 were randomly assigned into the minodronate (n = 36), denosumab (n = 36), and control (n = 30) groups. The percentage change in BMD at the lumbar spine was significantly improved in the minodronate (2.5%, p < 0.05) and denosumab groups (4.0%, p < 0.01) compared with that in the control group (- 0.1%). Denosumab increased BMD at the femoral neck and total hip at 12 months, whereas minodronate only increased BMD at the total hip compared with controls (all p < 0.05). The percentage change in bone turnover markers at 12 months was significantly lower in the minodronate and denosumab groups compared with that in the control group (both p < 0.01). CONCLUSION Minodronate or denosumab can be used for preventing bone loss related to ADT in Asian patients with PCa.

Abstract
The present retrospective cohort study was designed to determine body mass index (BMI) at the delivery in women undergoing cesarean section in a Japanese urban area, and whether the nerve block height after spinal anesthesia upon the cesarean delivery relates to the lower maternal BMI, less gestational age, or underweight fetus at birth in the population.A total of 401 pregnant women undergoing cesarean delivery with spinal anesthesia were evaluated retrospectively. We examined background differences, including BMI at the delivery, gestational age, and fetal birth weight between the cases with and without the adequate initial nerve block height less than the sixth thoracic vertebral level (Th6) after the spinal dose administration.The data demonstrated advanced maternal age pregnancy (median 35.5 years) and normal BMI (median 24.7) at the delivery in the population. The patients with the inadequate initial nerve block height immediately after the spinal dose administration documented significantly lower block height compared with those with adequate block height (Th8 [n = 55] vs Th4 [n = 346], P < 0.001). There was a risk of the low initial block height caused by either preoperative BMI <23, gestational age <37 weeks, or fetal birth weight <2500 g in the population.In a Japanese urban area, parturient median BMI undergoing cesarean delivery is in the normal range. Such lower BMI, in addition to less gestational age or underweight fetus, seems one of the factors causing the low initial block height upon spinal anesthesia.

Abstract
Abstract
Background
We previously demonstrated that a transcriptional repressor, neuron restrictive silencer factor (NRSF), maintains normal cardiac function and electrical stability. Transgenic mice expressing a dominant-negative mutant of NRSF in their hearts (dnNRSF-Tg) exhibit systolic dysfunction with cardiac dilation and premature death due to lethal arrhythmias like human dilated cardiomyopathy (DCM). Underlining mechanisms remain to be elucidated, however.
Purpose
We studied underling mechanisms by which NRSF maintains normal cardiac function to identify novel therapeutic targets for heart failure.
Methods and results
We generated cardiac-specific NRSF knockout mice (NRSFcKO) and confirmed that cardiac phenotypes of NRSFcKO are similar to those of dnNRSF-Tg.
cDNA microarray analysis revealed that cardiac gene expression of GNAO1 that encodes Gαo, a member of inhibitory G protein Gαi family, is increased in both dnNRSF-Tg and NRSFcKO ventricles.
We confirmed that GNAO1 is a direct target of NRSF through ChIP-seq analysis, reporter assay and electrophoretic mobility shift assay.
In dnNRSF-Tg, pharmacological inhibition of Gαo with pertussis toxin improved systolic dysfunction and knockdown of Gαo by crossing with GNAO1 knockout mice improved not only systolic function but also frequency of ventricular arrhythmias and survival rates.
Electrophysiological and biochemical analysis in ventricular myocytes obtained from dnNRSF-Tg demonstrated that genetic reduction of Gαo ameliorated abnormalities in Ca2+ handling, which include increased current density in surface sarcolemmal L-type Ca2+ channel, reduced content of sarcoplasmic reticulum Ca2+ and lowered peak of Ca2+ transient. Furthermore, genetic reduction of Gαo attenuated increased phosphorylation levels of CAMKII in dnNRSF-Tg ventricles, which presumably underlies the improvement in Ca2+ handling. In addition, we identified increased Gαo expression in ventricles of heart failure model mice induced by transverse aortic constriction and cardiac troponin T mutant DCM model mice, in both of which, genetic reduction of Gαo ameliorated cardiac dysfunction.
Figure 1
Conclusions
We found that increased expression of Gαo, induced by attenuation of NRSF-mediated repression, plays a crucial role in the progression of cardiac dysfunction and lethal arrhythmias by evoking Ca2+ handling abnormality. These data demonstrate that Gαo is a potential therapeutic target for heart failure.

Abstract
Although daily variations of blood pressure (BP) predict cardiovascular event risk, their assessment requires ambulatory BP monitoring which hinders the clinical application of this approach. Since the baroreflex is a major determinant of BP variations, especially in the frequency range of 0.01-0.1 Hz (baro-frequency), we hypothesized that the power spectral density (PSD) of short-term BP recordings in the baro-frequency range may predict daily variations of BP. In nine-week-old Wister-Kyoto male rats (N =5) with or without baroreflex dysfunction, we telemetrically recorded continuous BP for 24 hours and estimated PSD using Welch's periodogram for the recordings during the 12-hour light period. We compared the reference PSD of 12-hour recording with the PSDs obtained from shorter data lengths ranging from 5 to 240 minutes. The 30-minute BP recordings reproduced PSD of 12-hour recordingswell, and PSD in the baro-frequency range paralleled the standard deviation of 12-hour BP. Thus, the PSD of 30-minute BP reflects the daily BP variability in rats. In human subjects, we estimated PSD from 30-minute noninvasive continuous BP recordings. The rat and human PSDs shared remarkably similar characteristics. Furthermore, comparison of PSD between elderly and young subjects suggested that the baro-frequency range in humans overlapped with that in rats. In conclusion, PSD derived from 30-minute BP recordings is capable of predicting daily BP variations. Our proposed method may serve as a simple, noninvasive and practical tool for predicting cardiovascular events in the clinical setting.

Abstract
BACKGROUND AND AIMS Local macrophage proliferation is linked to enhanced atherosclerosis progression. Our previous study found that troglitazone, a thiazolidinedione (TZD), suppressed oxidized low-density lipoprotein (Ox-LDL)-induced macrophage proliferation. However, its effects and mechanisms are unclear. Therefore, we investigated the effects of pioglitazone, another TZD, on macrophage proliferation. METHODS Normal chow (NC)- or high-fat diet (HFD)-fed apolipoprotein E-deficient (Apoe-/-) mice were treated orally with pioglitazone (10 mg/kg/day) or vehicle (water) as a control. Mouse peritoneal macrophages were used in in vitro assays. RESULTS Atherosclerosis progression was suppressed in aortic sinuses of pioglitazone-treated Apoe-/- mice, which showed fewer proliferating macrophages in plaques. Pioglitazone suppressed Ox-LDL-induced macrophage proliferation in a dose-dependent manner. However, treatment with peroxisome proliferator-activated receptor-γ (PPARγ) siRNA ameliorated pioglitazone-induced suppression of macrophage proliferation. Low concentrations (less than 100 μmol/L) of pioglitazone, which can suppress macrophage proliferation, activated PPARγ in macrophages, but did not induce macrophage apoptosis. Pioglitazone treatment did not induce TUNEL-positive cells in atherosclerotic plaques of aortic sinuses in Apoe-/- mice. CONCLUSIONS Pioglitazone suppressed macrophage proliferation through PPARγ without inducing macrophage apoptosis. These findings imply that pioglitazone could prevent macrovascular complications in diabetic individuals.

Abstract
UNLABELLED We compared the effectiveness of promoting bone healing between two teriparatide preparations for atypical femoral fracture (AFF). A total of 45 AFFs were included in this study, and we compared the duration of bone union. Teriparatide administered by daily injection enhanced bone union more than weekly administration in complete AFFs. INTRODUCTION The efficacy of teriparatide for atypical femoral fracture (AFF) has been recently reported. Although two different teriparatide preparations can be used to treat osteoporosis in Japan, daily or weekly injection, all previous reports on the effectiveness of teriparatide for AFF only examined daily injection formulations. Therefore, we compared the promotion of bone healing between the two teriparatide preparations for AFF. METHODS A total of 45 consecutive AFFs in 43 Japanese patients were included in this study. They received either a daily 20-μg teriparatide injection (daily group; n = 32) or a once-a-week 56.5-μg teriparatide injection (weekly group; n = 13). We compared the clinical background and duration of bone union between these two groups. RESULTS When all patents were included, the fracture healing time was not significantly different between the two groups. Only patients with complete AFFs had significantly fewer daily bisphosphonate or denosumab injections than the weekly group (P < 0.05). The fracture healing time in the daily group (6.1 ± 4.1 months) was significantly shorter than that in the weekly group (10.1 ± 4.2 months) (P < 0.05). Even if the influence of bisphosphonate or denosumab usage was excluded, a similar significant difference was observed in the fracture healing time (P < 0.05). There was no significant difference between the two groups among patients with incomplete AFFs. CONCLUSIONS Daily teriparatide injections enhance bone union more than weekly injections in complete AFF patients.
