Study design In this study, we decided to change the activity of periaqueductal gray (PAG)'s metabotropic glutamate receptors subtype 8 (mGluR8) by means of its specific agonist, (S)-3,4-dicarboxyphenylglycine (DCPG), and by knock downing it with mGluR8 siRNA. We then evaluated the changes in animal pain threshold levels in the face of painful thermal stimuli (thermal hyperalgesia). GYY4137 purchase Purpose Although several mechanisms have been examined for central neuropathic pain, researchers have so far failed to find the precise mechanism for the development and progression of this type of pain. Hyperalgesia is one of the most important complications of central neuropathic pain and there is not a consensus among researchers about the exact cause of this complication. In this study, we investigated the effect of activation of the PAG region mGluR8 on the threshold of pain response to thermal noxious stimulus in rats and measured mGluR8 expression. Overview of literature Spinal cord injury (SCI) produces an decrease in mGluagonist did not significantly improve the tail-flick response. Conclusions The results revealed that activation of mGluR8 in PAG is not capable of improving the thermal hyperalgesia threshold. Based on the decreased expression of mGluR8 after SCI induced by clip compression injury and its significant increase after treatment of siRNA against mGluR8, this method might still hold promise as an effective treatment of neuropathic pain. It can be concluded that increased expression of mGluR8 is due to the fact that DCPG prevents the death of neurons that express these receptors.Study design This investigation was a retrospective observational study. Purpose The aim of this study was to evaluate whether having diffuse idiopathic skeletal hyperostosis (DISH) as a comorbidity affects the patient's ability to perform activities of daily living (ADL) after surgical treatment for osteoporotic vertebral fracture (OVF). Overview of literature A few studies have extensively evaluated elderly patients with comorbidities such as DISH and OVFinduced persistent back pain and their ability to perform ADL postoperatively. Methods In this study, 63 patients (21 men and 42 women) who underwent surgical treatment for OVF were enrolled. Of these patients, 26 had DISH (D+) and 37 did not have DISH (D-). Patient demographic characteristics and surgical, clinical, and radiological findings were compared between those with and without DISH. The change in their ability to perform ADL after surgery was also evaluated. Results Age, number of comorbidities, and 1-year mortality rate were significantly higher lderly patients.Study design Single-center retrospective study. Purpose We aimed to explore the postoperative prognostic factors for spinal intramedullary ependymoma. Overview of literature Ependymoma (World Health Organization grade II) is the most frequent intramedullary spinal tumor and is treated by total resection. However, postoperative deterioration of motor function occasionally occurs. Methods Eighty patients who underwent surgical resection at Keio University and Fujita Health University in Tokyo, Japan between 2003 and 2015 with more than 2 years of follow-up were enrolled. A good surgical result was defined as an improvement in the modified McCormick Scale score by one grade or more or having the same clinical grade as was observed preoperatively. Meanwhile, a poor result was defined as a reduction in the McCormick Scale score of one grade or more or remaining in grade IV or V at final follow-up. Univariate and multivariate logistic regression analyses of the following factors were performed in the two groups sexof surgery for spinal intramedullary ependymoma.Background The present study was designed to evaluate the effects of hypercarbia on arterial oxygenation during one-lung ventilation (OLV). Methods Fifty adult patients undergoing elective video-assisted thoracoscopic lobectomy or pneumonectomy were enrolled. Group 1 patients (n = 25) were first maintained in normocarbia (PaCO2 38 - 42 mmHg) for 30 min and then in hypercarbia (45 - 50 mmHg). In group 2 patients (n = 25), PaCO2 was maintained in the reverse order. Arterial oxygen partial pressure (PaO2), respiratory variables, hemodynamic variables, and hemoglobin concentration were compared during normocarbia and hypercarbia. Arterial O2 content and O2 delivery were calculated. Results PaO2 values during normocarbia and hypercarbia were 66.5 ± 10.6 mmHg and 79.7 ± 17.3 mmHg, respectively, (mean difference 13.2 mmHg, 95% CI for difference of means 17.0 to 9.3, P less then 0.001). SaO2 values during normocarbia and hypercarbia were 92.5 ± 4.8% and 94.3 ± 3.1% (P = 0.009), respectively. Static compliance of the lung (33.0 ± 5.4 vs. 30.4 ± 5.3 mL/cmH2O, P less then 0.001), arterial O2 content (15.4 ± 1.4 vs. 14.9 ± 1.5 mL/dL, P less then 0.001) and O2 delivery (69.9 ± 18.4 vs. 65.1 ± 18.1 mL/min, P less then 0.001) were significantly higher during hypercarbia than during normocarbia. Conclusions Hypercarbia increases PaO2 and O2 carrying capacity and improves pulmonary mechanics during OLV, suggesting that it may be helpful to manage oxygenation during OLV. Therefore, permissive hypercarbia may be a simple and valuable modality to manage arterial oxygenation during OLV.Background/aims Suboptimal responses to lamivudine or telbivudine plus adefovir (LAM/LdT+ADV) rescue therapy are common in patients with LAM-resistant hepatitis B virus (HBV) infections. We compared patients switched to entecavir plus tenofovir (ETV+TDF) to those maintained on LAM/LdT+ADV. Methods This prospective randomized controlled trial examined 91 patients whose serum HBV DNA levels were greater than 60 IU/mL after at least 24 weeks of treatment with LAM/LdT+ADV for LAM-resistant HBV. Patients were randomized to receive a new treatment (ETV+TDF, n=45) or maintained on the same treatment (LAM/LdT+ADV, n=46) for 48 weeks. Patients with baseline ADV resistance were excluded. Results Compared to LAM/LdT+ADV group, ETV+TDF group had more patients with a virologic response (42/45 [93.33%] vs. 3/46 [6.52%], P less then 0.001) and had a greater mean reduction in serum HBV DNA level from baseline (-4.16 vs. -0.37 log10 IU/mL, P less then 0.001). Multivariate analysis indicated that high baseline HBV DNA level (P=0.
