BACKGROUND: It has been recently suggested that gamma-glutamyltransferase (GGT) is independently associated with cardiovascular mortality and atherosclerosis, so the present study evaluated whether GGT is an additional marker of arterial stiffness, independent of other risk factors, in screening cohorts. METHODS AND RESULTS: The 1,387 individuals (741 men, 646 women) who underwent brachial - ankle pulse wave velocity (baPWV) measurement had their serum levels of GGT, creatinine, uric acid, C-reactive protein, lipids, fasting glucose and insulin, and their hepatitis profiles checked. There were statistically significant increments of baPWV according to quartile of GGT, which was statistically significant in women, but not in men. In logistic regression analysis, age, diabetes mellitus, GGT, heart rate, history of hypertension, triglyceride, and systolic blood pressure were significant variables that influenced increased pulse wave velocity (PWV). After age-and blood pressure-adjustment, GGT, homeostatic model assessment-insulin resistance, heart rate, history of hypertension, and metabolic syndrome were significant variables in men, and in women metabolic syndrome and history of hypertension were significant contributors to increased PWV. CONCLUSION: The present study results suggest that serum GGT may be an additional marker of arterial stiffness, especially in men, though the relationship with arterial stiffness was very weak. Further studies are needed to elucidate the mechanism of GGT's contribution to arteriosclerosis and to confirm the current results. 相似文献

Heat shock protein 70 (HSP70) is a molecular chaperone which plays an important role in cellular protection against various stressful stimuli and in the regulation of cellular growth and apoptosis. This study was conducted in gastric carcinoma (GC) to assess correlations of HSP70 expression with clinicopathological parameters and overall survival (OS). Tissue microarray blocks were constructed from 172 GCs and immunohistochemically stained for HSP70. Low HSP70 expression was found in 122 GCs (71 %), whereas 50 (29 %) had high expression. HSP70 expression was higher in tumours in the cardia (p?=?0.008), with non-signet ring cell histology (p?<?0.001), of intestinal type (p?=?0.045) and of higher pathological T stage (p?=?0.026). When considering the cohort as a whole, HSP70 expression did not correlate with OS (p?=?0.092). In intestinal type carcinomas, however, high HSP70 expression significantly correlated with worse OS (p?=?0.034). These results suggest that HSP70 expression might be an unfavourable prognostic factor in patients with GC, especially of intestinal type. 相似文献

BackgroundThere is increasing interest in the quality of health care and considerable efforts are being made to improve it. Rheumatoid arthritis (RA) is a disease that can result in favorable outcomes when appropriate diagnosis and treatment are provided. However, several studies have shown that RA is often managed inappropriately. Therefore, the Korean College of Rheumatology aimed to develop quality indicators (QIs) to evaluate and improve the health care of patients with RA.MethodsPreliminary QIs were derived based on the existing guidelines and QIs for RA. The final QIs were determined through two separate consensus meetings of experts. The consensus was achieved through a panel of experts who voted using the modified Delphi method.ResultsFourteen final QIs were selected among 70 preliminary QIs. These included early referral to and regular follow-up with a rheumatologist, radiographs of the hands and feet, early initiation and maintenance of disease-modifying anti-rheumatic drug (DMARD) therapy, periodic assessment of disease activity, screening for drug safety and comorbidities, including viral hepatitis and tuberculosis before biologic DMARD therapy, periodic laboratory testing, supplementation with folic acid, assessment of the risk for cervical spine instability before general anesthesia, patient education, and specialized nurse.ConclusionThese QIs can be used to assess and improve the quality of health care for patients with RA. 相似文献

Objective The purpose of this study was to evaluate the effects of adding music therapy (MT) to cognitive-behavioral therapy (CBT) on symptoms of smartphone/internet addiction and psychiatric comorbidities. Methods Overall, 155 patients diagnosed with addiction were assigned to either the CBT-MT group or CBT group. Both groups received CBT for 8 weeks, while the CBT-MT group received additional MT. The intervention was completed by 67 and 71 participants in the CBT-MT and CBT groups, respectively. Results The total scores of Young Internet Addiction Scale (YIAT) and Smartphone Addiction Proneness Scale (SAPS) decreased significantly (p<0.001 for both) in both groups, while the total scores of State Anxiety Inventory for Children (SAIC) (p<0.001), Trait Anxiety Inventory for Children (TAIC) (p<0.001), Conners-Wells’ Adolescent Self-Report Scale-Short form (CASS(S)) (p=0.048), and Barratt Impulsiveness Scale-11 (BIS-11) (p<0.001) decreased only in the CBT-MT group. The decrements in YIAT (p=0.025), SAIC (p=0.043), TAIC (p=0.011), and BIS-11 (p=0.012) in the CBT-MT group were significantly greater than those in the CBT group. Conclusion Combined MT and CBT improved the symptoms of smartphone/internet addiction, anxiety, and impulsivity in adolescents. This combination could therefore be an effective treatment of smartphone or internet addiction along with behavioral disorders such as anxiety and impulsivity. 相似文献

Objective This study examined how state and trait anxiety of adolescents with autism spectrum disorders (ASD) are associated with their demographic characteristics, repetitive and restricted behaviors (RRBs), and internalizing and externalizing problem behaviors. Methods A total of 96 participants with ASD (mean age=14.30 years; 91 males) completed a battery of tests including the State/Trait Anxiety Inventory (STAI), the Autism Diagnostic Interview-Revised, the Social Responsiveness Scale (SRS), and a cognitive test measuring intelligence quotient (IQ). Participants’ parents completed the Child Behavior Checklist (CBCL). Pearson’s correlations among age, IQ, two subscales of the STAI (i.e., STAIS and STAIT, measuring self-reported state and trait anxiety, respectively), and the Anxiety subscale of CBCL (i.e., CBCL-Anxiety, measuring parent-reported trait anxiety) were computed. Subsequently, Pearson’s correlations were computed among the three anxiety measures, RRBs, and problem behaviors, while controlling for participants’ age and IQ. Results The STAIS and CBCL-Anxiety were both significantly correlated with higher age, sensory sensitivity, depressive symptoms, somatic complaints, and aggressive behaviors. All three anxiety variables were significantly and positively correlated with total SRS RRB scores. Additionally, the STAIS and STAIT were significantly associated with more severe Compulsion/Adherence behaviors, and the CBCL-Anxiety was also significantly associated with more severe Rule-breaking Behaviors. Conclusion Self-reported state anxiety showed association patterns similar to those of parent-reported trait anxiety. Future studies investigating the precise operationalization of different anxiety instruments are needed to accurately measure the anxiety of adolescents with ASD. 相似文献

ObjectiveThis study aimed to examine the validity of the Korean version of the Autism Diagnostic Interview-Revised (K-ADI-R) and determine its efficacy in identifying individuals with autism spectrum disorder (ASD). MethodsData were pooled from several past and ongoing studies as well as clinical records acquired at Seoul National University Bundang Hospital from 2008 to 2017. The K-ADI-R were administered and scored by trained research reliable examiners. Measurements to investigate the validity of the K-ADI-R was through sensitivity, specificity, positive predictive values (PPV), negative predictive values (NPV), and Cohen’s kappa. ResultsA total of 1,271 (age 88.9±62.42 months, male=927) participants were included. The K-ADI-R yielded strong psychometric properties with high sensitivity (86.06–99.27%), specificity (84.75–99.55%), PPV (92.33–99.72%), and NPV (79.43–98.64%). There were significant differences in item scores across the K-ADI-R diagnostic algorithm regardless of age and sex (p<0.001). Agreement between the K-ADI-R and other ASD related measurements ranged between levels of good to excellent. ConclusionDespite language or cultural boundaries, the K-ADI-R demonstrated high levels of sensitivity, specificity, PPV, and NPV within a wide range of participants; hence, suggesting promising usage as a valuable diagnostic instrument for individuals with ASD. 相似文献

Background and PurposeThis study aimed to determine the long-term effects of vagus nerve stimulation (VNS) treatment on suicidality, mood-related symptoms, and quality of life (QOL) in patients with drug-resistant epilepsy (DRE). We also investigated the relationships among these main effects, clinical characteristics, and VNS parameters.MethodsAmong 35 epilepsy patients who underwent VNS implantation consecutively in our epilepsy center, 25 patients were recruited to this study for assessing the effects of VNS on suicidality, mood-related symptoms, and QOL. The differences in these variables between before and after VNS treatment were analyzed statistically using paired t-tests. Multiple linear regression analyses were also performed to determine how the patients'' demographic and clinical characteristics influenced the variables that showed statistically significant changes after long-term VNS treatment.ResultsAfter VNS, our patients showed significant improvements not only in the mean seizure frequency but also in suicidality, depression, and QOL. The reduction in depression was associated with the improvement in QOL and more-severe depression at baseline. The reduction in suicidality was associated with higher suicidality at baseline, smaller changes in depression, and less-severe depression at baseline. Improved QOL was associated with lower suicidality at baseline.ConclusionsThis study found that VNS decreased the mean seizure frequency in patients with DRE, and also improved their depression, suicidality, and QOL. These results provide further evidence for therapeutic effect of VNS on psychological comorbidities of patients with DRE. 相似文献

Nowadays, infectious aortitis has become a rare disease thanks to antibiotics, but remains life-threatening. We present a case of a patient with acupuncture-induced infectious aortitis leading to aortic dissection. Chest computed-tomogram scan revealed Stanford type A dissection with pericardial effusion. Under the impression of an impending rupture, emergent surgery was performed. During surgery, infectious aortitis was identified incidentally, so she underwent resection of the infected aorta including surrounding tissues. Then the ascending aorta and hemi-arch were replaced with a prosthetic graft as an in situ fashion. The resected tissue and blood cultures revealed Staphylococcus aureus, so prolonged antibiotherapy was prescribed. 相似文献
