Effect of cognitive behavioral intervention on anxiety, depression, and quality of life in patients with epilepsy.

OBJECTIVE: This study aimed to investigate the effect of cognitive behavioral therapy (CBT) on quality of life, anxiety, and depression in patients with epilepsy. METHODS: Each study subject was randomly assigned to a CBT (n=46) or control (n=49) group (1:1 ratio), and the first group underwent an 8-week CBT treatment. Anxiety, depression, and quality of life (QOLIE-31) were assessed at both baseline and endpoint using the Self-Rating Anxiety Scale (SAS), Hamilton Depression Scale (HDMA) and quality of life in Epilepsy-31 (QOLIE-31) scales. The statistical analyses included between-and within-group comparisons of the effects of CBT on these measures and associations with demographic and clinical variables. RESULTS: No differences were found between variables at baseline (P>0.05). The repeated-measures analyses found that CBT group had greater improvement in depression score compared to the control group (P<0.05). The analysis of anxiety score showed that compared to the control group, CBT intervention had no statistical significance in the total anxiety population. However, the CBT intervention decreased anxiety in women and Combined-drug group (P<0.05). The CBT group had greater improvement in overall score, medication effect, and seizure worry score than the control group (P<0.05). Stratified analysis found total and medication effects score of CBT intervention group for the combined-drug group were higher than those of the single drug group (P<0.05). CONCLUSION: Increases in overall scores, seizure worry, cognitive functioning, and medication effect were better in the CBT group. CBT can improve anxiety, depression, and quality of life in patients with epilepsy. Women and combined-drug patients with epilepsy benefit most from CBT.

A tract-based spatial statistics study of white matter integrity in epilepsy.

OBJECTIVE: To explore the changes of cerebral white matter diffusion tensor in epilepsy. METHODS: This study was a retrospective study based on diffusion tensor imaging (DTI). Twenty-six epileptic patients and 42 normal controls matched for sex, age and handedness were enrolled in our research. Based on the method of tract-based spatial statistics (TBSS), we analyzed the changes of each relevant parameter index of DTI in white matter of the brain in all subjects, including fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD) and radial diffusivity (RD). RESULTS: In comparison with the control group, epileptic patients had decreased FA and elevated MD, AD, and RD in the anterior thalamic radiation, corticospinal tract, forceps major, forceps minor, cingulum, inferior fronto-occipital fasciculus, inferior longitudinal fasciculus, superior longitudinal fasciculus and uncinate fasciculus (P < 0.05). CONCLUSION: Widespread white matter integrity was observed in epileptic patients, which may be the structural basis for the development of affective disorders, impaired cognition, and motor abnormalities.

T-lymphocyte subsets as a predictive biomarker for stroke-associated pneumonia.

The aim of this study was to facilitate the clinical treatment and prognosis of stroke-associated pneumonia (SAP) by examining changes in T-lymphocyte subsets. Stroke patients admitted in Suzhou Hospital between 2014 and 2016 participated in the study. Patients were divided into a pneumonia group (50 patients) and a non-pneumonia group (254 patients) based on a diagnosis of pneumonia. Information regarding risk factors for ischemic stroke was collected from all patients using a questionnaire. Compared with non-SAP patients, SAP patients were older, dysphagic, smokers, had higher NIH stroke scale (NIHSS) scores and neutrophil: lymphocyte ratio, had higher leukocyte, neutrophil, and CD8 levels, had lower CD3, CD4, and lymphocyte levels, and had a lower CD4:CD8 ratio. Patients with a higher NIHSS score had higher CD8 levels, lower CD3 and CD4 levels, and a lower CD4:CD8 ratio. No significant differences in T-lymphocyte subsets were found between the left and right cerebral hemispheres. After adjusting for other variables, smoking, dysphagia, NIHSS score, and CD4:CD8 ratio were positively associated with SAP. The areas under the receiver operating characteristic curve for dysphagia, NIHSS score, CD4:CD8 ratio, CD4:CD8 ratio + NIHSS score, and Dysphagia+ CD4:CD8 ratio + NIHSS score were 0.583 (95% CI: 0.490-0.675), 0.791 (95% CI: 0.724-0.859), 0.676 (95% CI: 0.593-0.759), 0.846 (95% CI: 0.790-0.902), and 0.867 (95% CI: 0.815-0.918), respectively. A few T-lymphocyte subsets may increase susceptibility to pneumonia after acute ischemic stroke. Thus, the detection of T-lymphocyte subsets may predict the risk of SAP in such patients.

Influence of renal function on the association between homocysteine level and risk of ischemic stroke.

We examined whether the association between total homocysteine (tHCY) and risk of ischemic stroke (IS) varies depending on renal function to gain insight into why tHCY-lowering vitamins do not reduce the incidence of cardiovascular disease in clinical trials. We analyzed data from 542 IS patients with large artery atherosclerosis (LAA) or small artery occlusion (SAO) after stratification by estimated glomerular filtration rate (eGFR) to evaluate renal function. We found that tHCY level was positively associated with the occurrence of IS in both LAA (OR: 1.159, 95% CI: 1.074-1.252, P<0.001) and SAO (OR: 1.143, 95% CI: 1.064-1.228, P<0.001) patients and in LAA (OR: 1.135, 95% CI: 1.047-1.230, P=0.002) and SAO (OR: 1.159, 95% CI: 1.060-1.268, P=0.001) subgroups with normal renal function but not in LAA or SAO subgroups with renal insufficiency. eGFR level was positively associated with IS in LAA (OR: 1.022, 95% CI: 1.010-1.034, P<0.001) and SAO (OR: 1.024, 1.012-1.037, P<0.001) subgroups with normal renal function but was negatively associated with IS in LAA (OR: 0.875, 95% CI: 0.829-0.925, P<0.001) and SAO (OR: 0.890, 95% CI: 0.850-0.932, P<0.001) subgroups with renal insufficiency. Folic acid level was negatively associated with IS in LAA (OR: 0.734, 95% CI: 0.606-0.889, P=0.002) and SAO (OR: 0.861, 95% CI: 0.767-0.967, P=0.012) subgroups with renal insufficiency. Therefore, renal function as evaluated by eGFR exerts a significant influence on the association between tHCY and risk of IS.

The Neural Basis of Postural Instability Gait Disorder Subtype of Parkinson's Disease: A PET and fMRI Study.

AIMS: The aim of this study is to further uncover the neural basis of postural instability gait disorder (PIGD) subtype of Parkinson's disease. METHODS: With F-18 fluorodeoxyglucose PET (FDG-PET), brain glucose metabolism of patients with PIGD (n = 15) was compared with healthy controls (n = 17) and tremor-dominant (TD) patients (n = 15), and the correlation between metabolism and PIGD symptoms was also assessed. Within PIGD symptom-correlated hypometabolic areas, the relationship of functional connectivity (FC) with motor and cognitive symptoms was examined by using functional MRI. RESULTS: Compared with controls, patients with PIGD displayed a distributed pattern of brain hypometabolism including striatal, frontal, and parietal areas. Relative to the pattern of TD patients, the pattern of patients with PIGD had additional metabolic decreases in caudate and inferior parietal lobule (IPL, Brodmann area [BA] 40). In PIGD group, the metabolic reductions in IPL (BA 40), middle frontal gyrus (MFG, BA 9) and fusiform gyrus (FG, BA 20) were associated with severe PIGD symptoms. Regions showing such correlation were chosen for further seed-based FC analysis. Decreased FC within the prefrontal-parietal network (between the MFG and IPL) was associated with severe PIGD symptoms. CONCLUSION: The involvement of the caudate, FG, and prefrontal-parietal network may be associated with the prominent gait impairments of PIGD subtype. Our findings expand the pathophysiological knowledge of PIGD subtype and provide valuable information for potential neuromodulation therapies alleviating gait disorders.

The association between clinically relevant anxiety and other non-motor symptoms in Parkinson's disease.

Anxiety disorders in patients with Parkinson's disease (PD) are often missed due to an overlap with other non-motor symptoms. The relationships between anxiety and other non-motor symptoms in PD still remain unclear. We used the Hamilton anxiety rating scale and the Non-motor Symptoms Questionnaire to measure anxiety and the complex range of non-motor symptoms in 99 PD patients. The relationships between anxiety and other PD-related non-motor symptoms were examined through regression analyses. 25 % of PD patients were diagnosed with clinically relevant anxiety. Non-motor symptoms were more prominent in patients with anxiety. Depression, urinary disorders, and sleep disruption were the factors most likely to influence anxiety in PD. Our findings have revealed a strong interplay between anxiety and other non-motor symptoms of PD and have highlighted the need for a holistic approach towards the clinical treatment of this disabling condition.

[Risk factors of intrahepatic cholangiocarcinoma: a case-control study].

OBJECTIVE: To explore the potential risk factors of intrahepatic cholangiocarcinoma (ICC) in China. METHOD: A case-control study including 317 patients with pathologically confirmed ICC and 634 healthy individuals was conducted. The cases and controls were matched in age, sex and inhabitancy. Data were statistically analyzed by Chi-square test and conditional logistic regression. RESULTS: Univariate analysis showed significant difference in HBsAg seropositivity, liver cirrhosis, hepatolithiasis, choledocholithiasis and schistosomiasis between ICC patients and healthy controls (P < 0.05). Multivariate analysis confirmed that HBsAg seropositivity, liver cirrhosis, hepatolithiasis and hepatic schistosomiasis were associated with ICC, and their adjusted odds ratio (95% confidence interval) were 10.265 (6.676-15.783), 13.101 (5.265-32.604), 18.242 (3.580-92.958), 18.435 (1.930-176.082), 15.102 (4.607-49.499) and 11.820 (3.522-39.668), respectively. The incidence of hepatic cyst, cholecystolithiasis, hepatic hemangioma, fatty liver, diabetes mellitus, smoking and drinking were not significantly different between ICC patients and controls. CONCLUSIONS: The HBV infection, liver cirrhosis, hepatolithiasis and hepatic schistosomiasis may be the risk factors for ICC in China.
