Clinical characteristics of heavy alcohol consumption in young and middle-aged acute cerebral infarction: A 12-month follow-up study.

Objective: To investigate the clinical characteristics and prognosis of heavy alcohol consumption among young and middle-aged patients with acute cerebral infarction (ACI). Methods: A total of 263 young and middle-aged ACI patients were included in the study from June 2018 to December 2020 and classified into heavy drinkers and non-heavy drinkers. Multivariate logistic regression analysis was conducted to assess the association between ACI and heavy alcohol consumption, considering clinical characteristics and one-year post-discharge prognosis. Results: Among the patients, 78 were heavy drinkers. Heavy drinkers were more likely to consume alcohol 24 h before ACI onset (OR 4.03, 95 % CI 2.26-7.20), especially in the form of liquor (OR 3.83, 95 % CI 1.59-9.20), and had a higher risk of diastolic blood pressure ≥90 mmHg upon admission (OR 2.02, 95 % CI 1.12-3.64). In the one-year post-discharge prognosis, heavy drinkers had a greater likelihood of poor prognosis at 3 months (OR 2.31, 95 % CI 1.01-5.25), were less likely to quit drinking after discharge (OR 0.36, 95 % CI 0.19-0.66), and had a higher risk of recurrent cerebral infarction (OR 2.79, 95 % CI 1.14-6.84). Conclusions: Over the 12-month follow-up, young and middle-aged ACI patients with heavy alcohol consumption exhibited worse short-term prognosis. Controlling alcohol consumption levels may improve the prognosis of these patients.

Assessment of bidirectional relationships between multiple sclerosis and epilepsy: A two-sample Mendelian randomization study.

BACKGROUND AND OBJECTIVE: Epidemiological studies indicate that multiple sclerosis (MS) is associated with epilepsy. However, the causality and directionality of this association remain under-elucidated. This study aimed to reveal the causality between MS and epilepsy. METHODS: A two-sample Mendelian randomization (MR) analysis was performed by using summarized statistics derived from large genome-wide association studies of MS and epilepsy. We used the inverse variance weighted method as the primary approach, and then four other MR methods to bidirectionally evaluate the causality of the association between MS and epilepsy. Additional sensitivity analyses were performed to measure the robustness of the findings. RESULTS: Genetically predicted MS was positively correlated with developing all epilepsy [odds ratio (OR) = 1.027 (1.003-1.051), P  =  0.028] and generalized epilepsy [OR = 1.050 (1.008-1.094), P = 0.019]. In the reverse MR analysis, all epilepsy [OR = 1.310 (1.112-1.543), P = 0.001], generalized epilepsy [OR = 1.173 (1.010-1.363), P = 0.037], and focal epilepsy [OR = 1.264 (1.069-1.494), P  =  0.006] elevated the risk of developing MS. The result remained robust and congruous across all sensitivity analyses conducted. CONCLUSIONS: MS is potentially associated with a higher risk of developing epilepsy. Furthermore, epilepsy may be a causal determinant of MS risk. These findings may further the understanding of the interaction of the two conditions.

Parkinson's disease patients with freezing of gait have more severe voice impairment than non-freezers during "ON state".

BACKGROUND: Speech disorders and freezing of gait (FOG) in Parkinson's disease (PD) may have some common pathological mechanisms. The purpose of this study was to compare the acoustic parameters of PD patients with dopamine-responsive FOG (PD-FOG) and without FOG (PD-nFOG) during "ON state" and explore the ability of "ON state" voice features in distinguishing PD-FOG from PD-nFOG. METHODS: A total of 120 subjects, including 40 PD patients with dopamine-responsive FOG, 40 PD-nFOG, and 40 healthy controls (HCs) were recruited. All subjects underwent neuropsychological tests. Speech samples were recorded through the sustained vowel pronunciation tasks during the "ON state" and then analyzed by the Praat software. A set of 27 voice features was extracted from each sample for comparison. Support vector machine (SVM) was used to build mathematical models to classify PD-FOG and PD-nFOG. RESULTS: Compared with PD-nFOG, the jitter, the standard deviation of fundamental frequency (F0SD), the standard deviation of pulse period (pulse period SD) and the noise-homophonic-ratio (NHR) were increased, and the maximum phonation time (MPT) was decreased in PD-FOG. The above voice features were correlated with the freezing of gait questionnaire (FOGQ). The average accuracy, specificity, and sensitivity of SVM models based on 27 voice features for classifying PD-FOG and PD-nFOG were 73.57%, 75.71%, and 71.43%, respectively. CONCLUSIONS: PD-FOG have more severe voice impairment than PD-nFOG during "ON state".

A novel scoring system to predict the outcomes of adult patients with hypoxic-ischemic encephalopathy.

BACKGROUND: Adult patients with hypoxic-ischemic encephalopathy (HIE) often incur large costs, but their outcomes are poor. Currently, there is lack of a comprehensive quantitative approach to predict patient prognoses. METHODS: A total of 73 adult patients with HIE participated in this prospective, observational study. Clinical assessments, laboratory tests, and electrophysiological examinations were conducted within 3 days after HIE occurred. Logistic regression model was used to identify independent factors associated with patient outcomes. RESULTS: After a 6-month follow-up, 44 (61.1%) patients survived, 28 (38.9%) patients died, and one patient was lost to follow-up. The level of blood calcium and lactate, the presence of electroencephalography reactivity, and Glasgow Coma Scale (GCS) score were significantly associated with the patient's outcome. Based on the regression coefficients from logistic regression analysis, we constructed a scoring system (CEGL; C: calcium, E: EEG reactivity, G: GCS, L: lactate) to predict the possibility of a patient's death. The area under the receiver operating characteristic curve was 0.91 (P < 0.001, 95% CI [0.87-0.95]) with a specificity of 97.7% and a positive predictive value of 97.4%. CONCLUSION: CEGL score can provide clinicians useful information for assessment of patient prognosis within 6 months after HIE.

Plasma levels of soluble receptor for advanced glycation end products in Alzheimer's disease.

BACKGROUND: A decreased plasma level of soluble form of the receptor for advanced glycation end products (sRAGE) in patients with Alzheimer's disease (AD) has been reported. However, no evidence has shown whether the sRAGE plasma level of AD patients may differentiate from other types of dementia. METHODS: Our study assessed sRAGE concentrations in the following 121 individuals in Chongqing area: 36 patients with AD, 12 with vascular dementia (VaD), 14 with mixed dementia (MD), 24 with other dementia (OD) including Parkinson's disease dementia, frontotemporal dementia, paralytic dementia and 35 cognitively normal controls. The total plasma level of sRAGE was determined using sandwich ELISA method. RESULTS: sRAGE concentration in AD is significantly decreased compared with healthy controls. However, the receiver operating characteristic curve analysis of sRAGE between the AD and the control shows a low diagnostic accuracy. CONCLUSIONS: Our results demonstrate that sRAGE may assist the diagnosis of AD from normal individuals, but cannot differentiate AD from VaD, MD or OD.

Systemic Family Therapy of Comorbidity of Anxiety and Depression with Epilepsy in Adolescents.

OBJECTIVE: The aim of this study was to find if systemic family therapy (SFT) does work in anxiety and depression with epilepsy in adolescents (ADAE). METHODS: 104 adolescents with epilepsy, aged 13-20 years old, were included from December 2009 to December 2010, the enrolled patients were with anxiety [Hamilton Anxiety Scale (HAMA) score ≥14 points] or depression [Hamilton Depression Scale (HAMD) score ≥20 points]. The patients were randomly divided into the control group (n=52) treated with antiepileptic drugs (AED) and the intervention group (n=52) undergone Systemic Family Therapy (SFT) as well as AED. The AED improvements, anxiety and depression scores, Social Support Rating Scale (SSRS), Family Assessment Device (FAD) and scale of systemic family dynamics (SSFD) were observed after 3-month treatment. RESULTS: The frequencies of epileptic seizures in intervention group was decreased much more significantly than the control group (4.22±3.54 times/month vs. 6.20±5.86 times/month, p=0.04); and the scores of anxiety (9.52±6.28 points vs. 13.48±8.47 points, p=0.01) and depression (13.86±9.17 points vs. 18.89±8.73 points, p=0.02) were significantly decreased than the control group; meanwhile, the family dynamics and family functions were significantly improved, and the social support was also increased (p<0.05). CONCLUSION: SFT combined with AEDs had better efficacies than AEDs alone, not only the frequency of epileptic seizures was decreased, but also the patients' anxiety and depression were improved, and the family dynamics, family functions and social support were improved.

Investigation of pulmonary infection pathogens in neurological intensive care unit.

PURPOSE: The purpose of this study is to investigate the distribution and antimicrobial susceptibility of pathogenic bacteria in inpatients with pulmonary infection in the neurological intensive care unit (NICU). METHODS: A total of 947 sputum specimens of 428 inpatients from May 2007 to May 2008 in the NICU were enrolled in the study, and bacterial identification and antibiotic susceptibility tests were analyzed using a VITEK 2 system. RESULTS: A total of 400 positive bacterial strains were separated from 947 sputum specimens, with Gram-negative bacteria accounting for 69.0% of the total strains collected. The most common strain of Gram-negative bacteria was Klebsiella pneumoniae (20.5%). Gram-positive bacteria accounted for 10.0% of the total strains, with the most common strain being Staphylococcus aureus (2.5%). Fungal species accounted for 21.0% of the total strains, and the most common strain collected was Candida albicans (12.25%). Imipenem was the most effective antibiotic against Gram-positive and Gram-negative bacteria. The drug resistance rate of Gram-positive bacteria to penicillin G was 100%, and the Gram-positive bacteria were 100% sensitive to teicoplanin, vancomycin, and linezolid. CONCLUSIONS: Gram-negative bacterial infections account for the majority of pulmonary infections in the NICU, with fungal infections being the second most common infection type observed. In addition, fungal infections seem to be related to mortality in the NICU.

Comparison of the retention rates between carbamazepine and valproate as an initial monotherapy in Chinese patients with partial seizures: A ten-year follow-up, observational study.

PURPOSE: To compare the long-term retention rates of the two most commonly prescribed antiepileptic drugs (AEDs), carbamazepine (CBZ) and valproate (VPA) as an initial monotherapy in Chinese patients with partial seizures. METHODS: This is a retrospective, observational study in a tertiary epilepsy centre. Overall, 584 patients were followed during a ten-year period. Kaplan-Meier survival analysis was used to estimate the cumulative probability of retention. Cox proportional hazard model was used to analyze the risk factors for retention rate. RESULTS: The calculated retention rates estimated by Kaplan-Meier survival analysis showed no difference between CBZ and VPA (p=0.074). During the time period from the first six months to two years, the lack of efficacy (LE) that led to drug discontinuation was 10.7% for CBZ compared to 4.5% for VPA (p=0.004). The adverse effects (AEs) that led to discontinuation was 2.4% for CBZ compared to 6.3% for VPA (p=0.025). Clinical control that led to discontinuation was 15.9% for CBZ compared to 7.5% for VPA (p=0.001). The five-year remission rate was higher in the CBZ group (33.3%) than in the VPA group (23.2%, p=0.006). Yet in the complex partial seizure subgroup, there was no significant difference between the two drugs (p=0.61). CONCLUSION: Compared with VPA, patients treated with CBZ were more likely to discontinue treatment for LE, and were less likely to discontinue for AEs; however, the two differences above only occurred in the time period between the first six months to two years of treatment. Long-term treatment with CBZ appeared to be more effective in terms of five-year remission and clinical control than VPA.
