RESUMEN

AIMS: To measure the therapeutic effect of an anti-oxidant, edaravone (EDV), or neurotrophic treatment with nerve growth factor (NGF) as an add-on treatment for alcohol-related brain damage (ARBD). DESIGN: Multi-centre, randomised, single-blinded, comparative clinical trial. SETTING AND PARTICIPANTS: One hundred and twenty-two inpatients recruited from seven hospitals in different regions of China, all diagnosed with ARBD and aged 18 to 65 years old; among them, only two were female. INTERVENTION AND COMPARATOR: Patients were randomly assigned to receive one of three treatments for 2 weeks: 40 patients, treatment as usual (TAU: a combination of intramuscular injections of thiamine, intravenous infusions of other B vitamins with vitamin C and oral medication with vitamin E per day); 40, EDV add-on treatment to TAU (intravenous infusion with 30 mg of EDV twice per day); and 42, NGF add-on treatment to TAU (intramuscular injection of 20 µg of NGF per day). The patients underwent follow-up for 24 weeks. MEASUREMENTS: The primary outcome was the composite score of executive cognitive function in the 2nd week after treatment, which was measured as the mean of the Z scores of the assessments, including the digit symbol substitute test (DSST), digit span memory test-forward (DST-F), digit span memory test-reverse (DST-R) and space span memory test (SSMT). The secondary outcomes were the composite scores at later follow-ups, the score for each component of cognitive function, global cognitive function measured by the Montreal Cognitive Assessment (MoCA), craving for alcohol and the safety of the therapies. FINDINGS: EDV add-on treatment improved the composite score of executive cognitive function better than TAU in the 2nd week (adjusted mean difference: 0.24, 95% confidence interval 0.06 to 0.41; P = 0.008), but NGF add-on treatment did not (adjusted mean difference: 0.07, 95% confidence interval -0.09 to 0.24; P = 0.502). During the follow-up to 24 weeks, EDV add-on treatment improved the composite score of executive cognitive function and DST-R score better than TAU (both P < 0.01). Craving for alcohol was relieved in all three groups. No severe adverse events were observed. CONCLUSION: The short-term addition of edaravone to supplementary therapy treatment for alcohol-related brain damage (ARBD) improved executive cognitive function in patients with ARBD.

RESUMEN

To examine the dose-response effect of mindfulness-based cognitive therapy (MBCT) for college students with major depressive disorder (MDD), a randomized control trial with MBCT and a wait-list (WL) group was performed. All participants were invited to self-administer a set of questionnaires at baseline, mid-intervention (4th week), and post-intervention (8th week) by the 9-item Patient Health Questionnaire (PHQ-9), the 7-item Generalized Anxiety Disorder scale (GAD-7), the Pittsburgh Sleep Quality Index (PSQI), the Five Facet Mindfulness Questionnaire (FFMQ), the Self-Compassion Scale (SCS). The serum levels of IL-1ß, IL-6, IL-8, TNF-α, BDNF were detected at baseline and post-intervention. After intervention, the scores of PHQ-9, GAD-7, PSQI, and the levels of IL-1ß, IL-6, IL-8 and TNF-α in the MBCT were significantly lower than those in WL group, and total scores of FFMQ, SCS, and the level of BDNF were significantly higher than those in WL group. In MBCT group, daily practice time and session numbers positively related to reduction rates of PHQ-9, GAD-7 and PSQI at post-intervention. The reduction rate of PHQ-9, GAD-7 and PSQI at post-intervention in the completers were higher significantly than those in the partial attendees. These findings suggested MBCT is effective for MDD, and the intervention has a dose-response effect. TRIAL REGISTRATION: Registration number is [ChiCTR2100044309].

RESUMEN

Background: Sufficient attention to trunk rehabilitation after stroke is still lacking. Loss of trunk selective activity is considered to be the leading cause of trunk postural control disorder after stroke. "Taking the Waist as the Axis" Therapy (WAT) was developed as a combination of the concept of "Taking the Waist as the Axis" from Tai Chi and the rehabilitation of trunk dysfunction after stroke. The present clinical trial examined and assessed the effects of WAT on stroke patients. Methods: A total of 43 stroke hemiplegic patients with trunk postural control disorder, whose Trunk Impairment Scale (TIS) scoring between 8 and 18, participated in the present study and were allocated randomly to the experimental (n = 23) or control groups (n = 20). The experimental group received WAT plus conventional therapy, and the control group received "Trunk Selective Activity" Therapy (TSAT) plus conventional therapy. Both groups received treatment once daily and 5 times per week for 3 weeks. The Trunk Impairment Scale (TIS), Fugl-Meyer Assessment (FMA), Berg Balance Scale (BBS), change of Intra-abdominal Pressure (IAP), static balance ability assessment, rapid ventilation lung function test and the Modified Barthel Index (MBI) were evaluated before and after intervention for both groups. Results: The experimental group was superior to the control group in TIS [4 (2, 5) vs. 3 (1.25, 4), p = 0.030], change of IAP [-3 (-8, -1.33) vs. -0.02 (-3.08, 6), p = 0.011], FMA-upper extremity [10 (6, 18) vs. 1 (0, 3), p = 0.002], FMA-lower extremity [2 (1, 4) vs. 1 (0, 2), p = 0.009] and FMA [14 (7, 21) vs. 2 (0.25, 3.75), p = 0.001]. Within experimental group, forced vital capacity (FVC) [81.35 (63.30, 94.88) vs. 91.75 (79.40, 97.90), p = 0.02] was significantly improved. Conclusion: WAT was an effective trunk treatment after stroke, which significantly improved the patients' trunk posture control ability, motor function and forced vital capacity. However, the results still need to be interpreted with caution for the intervention only lasted for 3 weeks.

RESUMEN

RATIONALE: Intentional or unintentional exposure to asphyxiating gases is a significant public health concern worldwide. Argon poisoning is fatal, and its onset is primarily due to neurological damage. PATIENT CONCERNS: A 22-year-old man was admitted to the hospital for argon gas poisoning. While working in a plant containing argon gas, he suddenly lost consciousness, recovered consciousness slightly after on-site treatment, answered questions, and had impaired memory, sensory dullness, normal cognition, and symptoms of dizziness and headache. DIAGNOSIS: Asphyxiating gas poisoning (argon gas poisoning), metabolic encephalopathy, and hepatic insufficiency. INTERVENTIONS: Immediately after admission, the patient was treated with nasal cannula oxygen 3 L/min and hyperbaric oxygen therapy once a day. Mecobalamin tablets 500 µg were given orally 3 times a day. Oral Ginkgo biloba extract tablets 40 mg 3 times a day. OUTCOME: The patient was discharged after treatment with hyperbaric oxygen therapy and nerve-nourishing drugs, with no discomfort, clear consciousness, and good memory, and was followed up by telephone for 2 consecutive months, and the patient is now in good condition with no discomfort. LESSON: This case describes the pathogenesis, neurological damage, and rescue process of argon gas poisoning. Argon poisoning was found to damage bilateral cerebellar hemispheres and bilateral hippocampal regions, affecting the patient's consciousness and memory, and was found to cause abnormal liver function and heart rate disorders.

RESUMEN

Objective: To examine the efficacy and the role of engagement of an internet-based Mindfulness-based Stress Reduction (iMBSR) for survivors of breast cancer (BC) during the COVID-19 period from January to March in 2020 in China. Methods: 48 survivors of BC were divided into the absentees group and the iMBSR groups according to their attending to the standardized, group-based, 8-week iMBSR. Based on practice time, survivors of BC in the iMBSR were categorized into three subgroups: group 1 (<30 min/day), group 2 (30-60 min/day), and group 3 (>60 min/day). In addition, participants were classified as partial attendees (<4 sessions) and completers (more than 4 sessions) of the iMBSR groups. All participants were evaluated for symptoms of depression, anxiety and insomnia at baseline, mid-intervention, and post-intervention. Results: After an 8-week iMBSR practice, at mid-intervention and post-intervention, participants in iMBSR group had significant improvement in scores and reduction rates of depression, anxiety, and insomnia compared to absentees. Scores of depression and insomnia, reduction rates of depression at post-intervention, scores of anxiety, reduction rates of anxiety and insomnia at mid-intervention and post-intervention, had significant differences among subgroups of practice time. Daily practice time was positively related to reduction rates of depression, anxiety and insomnia at post-intervention in the iMBSR group. Conclusion: Internet-based MBSR showed efficacy in reducing psychological symptoms among survivors of BC. For survivors of BC, iMBSR practice has a potential dose-response efficacy, with a threshold of >30 min daily practice for most optimal symptoms reduction. Trial Registration: Registration number is [ChiCTR2100044309].

RESUMEN

OBJECTIVES: To compare the effects of Liuzijue Qigong and conventional respiratory training on trunk control ability and respiratory muscle functions in patients at an early recovery stage from stroke. DESIGN: A single-blind, randomized controlled trial. SETTING: A hospital. PARTICIPANTS: Patients (N=60) within 2 months poststroke. INTERVENTIONS: The experimental group (n=30) received conventional rehabilitation training combined with Liuzijue exercise, and the control group (n=30) received conventional rehabilitation training combined with conventional respiration training. The training in the 2 groups was conducted 5 times per week for 3 weeks. MAIN OUTCOME MEASURES: Trunk Impairment Scale (TIS), maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP), forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), peak expiratory flow (PEF), maximum expiratory mid-flow (MMEF), diaphragmatic movement, the change of intra-abdominal pressure (IAP), Berg Balance Scale (BBS), and Modified Barthel Index (MBI). All outcome measures were assessed twice (at baseline and 3 weeks). RESULTS: Both groups significantly improved in TIS, MIP, FVC, PEF, and the change of IAP, BBS, and MBI when pre- and postassessments (P<.05) were compared. Compared with the control group, there was a significant difference in the experimental group in the static sitting balance subscale (P=.014), dynamic balance subscale (P=.001), coordination subscale (P<.001), TIS total scores (P<.001; effect size [ES]=0.9), MIP (P=.012; 95% confidence interval [CI], 2.23-17.69; ES=0.67), MEP (P=.015; 95% CI, 1.85-16.57; ES=0.65), change of IAP (P=.001), and MBI (P=.016; 95% CI, 1.51-14.16; ES=0.64). No significant differences were found between the 2 groups in FEV1 (P=.24), FVC (P=.43), PEF (P=.202), MMEF (P=.277), the diaphragmatic movement of quiet breathing (P=.146), deep breathing (P=.102), and BBS (P=.124). CONCLUSIONS: Liuzijue exercise showed more changes than conventional respiratory training in improving trunk control ability, respiratory muscle functions, and activities of daily living ability in patients at an early recovery stage from stroke.

RESUMEN

OBJECTIVE: This meta-analysis aimed to assess the efficacy and safety of glucocorticoid versus traditional therapy for hepatitis B virus (HBV)-related acute-on-chronic liver failure (ACLF). METHODS: PubMed, Cochrane Central Register of Clinical Trials, and EMBASE were searched. All clinical studies, including randomized controlled studies and cohort studies, comparing glucocorticoids with traditional treatments (until November 1, 2018), were included. RESULTS: A total of 3 randomized controlled trials and 5 cohort studies (including 3 retrospective cohort studies), involving 538 patients, were subjected to the meta-analysis. The total bilirubin levels before treatment were not significantly different (odds ratio [OR]: -0.97; 95% confidence interval [CI]: -2.56 to 0.62; P = .23), and, however, they were significantly reduced after treatment in the corticosteroid group compared with the traditional treatment group (OR: -8.83; 95% CI: -14.99 to 2.67; P = .005). Moreover, prothrombin time was significantly long before treatment in either group, with no significant differences (OR: 0.28; 95% CI: -0.79 to 1.34; P = 0.61). However, after treatment, prothrombin time was significantly shortened in the traditional treatment group (OR: 31.71; 95% CI: 3.62-59.81; P = .03). Furthermore, inpatient mortality (OR: 0.23; 95% CI: 0.08-0.67; P = .007) and ascites events (OR: 0.35; 95% CI: 0.18-0.67; P = .90) were significantly lower in the corticosteroid treatment group. CONCLUSIONS: Glucocorticoid is more effective for reducing the T-bili level, significantly decreasing in-hospital mortality and ascites events in HBV-related ACLF patients. Moreover, bilirubin may play a pivotal role in the early stage of HBV-related ACLF progression to advanced liver failure.

RESUMEN

Causal illness attributions influence how individuals cope with somatic symptoms and illnesses. Dimensions of causal symptom attributions have been examined in Western cultures with the subscale 'causes' of the revised Illness Perception Questionnaire (IPQ-R). Some previous studies have identified a stronger somatic attribution style in Asian patients. In this study it was examined if the factorial structure of causal attributions identified in Western populations can be identified in a large Chinese sample of patients presenting with somatic symptoms. We recruited 665 patients aged at least 18 who were visiting the hospital for reasons of treatment from departments of traditional Chinese medicine (TCM), neurology (Biomedicine), and psychosomatic medicine in six hospitals across China. All subjects completed the Patient Health Questionnaire (PHQ) and the causes subscale of the IPQ-R. We split the data-set by chance in two parts. On the first subsample, we conducted a confirmatory factor analysis (CFA) to check the fit of the originally proposed 4-factor structure and an exploratory factor analysis (EFA). The factor structure indentified in the EFA was rechecked with a CFA in the second subsample. The originally proposed 4-factor-model of the IPQ-R subscale causes showed no adequate fit in the first subsample. The EFA revealed two factors, psychological attributions and risk factors. The CFA in the second sample showed mediocre fit indices (RMSEA = .098, CFI = .923). For the Chinese sample we propose a two-factor structure for IPQ-R causes scale. As in other studies, we identified the relatively stable factor psychological attributions, indicating no fundamental differences in illness attributions between Western and Chinese samples.

RESUMEN

Istradefylline (KW-6002), an adenosine A2A receptor antagonist, is used adjunct with optimal doses of L-3,4-dihydroxyphenylalanine (l-DOPA) to extend on-time in Parkinson's disease (PD) patients experiencing motor fluctuations. Clinical application of istradefylline for the management of other l-DOPA-induced complications, both motor and non-motor related (i.e. dyskinesia and cognitive impairments), remains to be determined. In this study, acute effects of istradefylline (60-100 mg/kg) alone, or with optimal and sub-optimal doses of l-DOPA, were evaluated in two monkey models of PD (i) the gold-standard 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-treated macaque model of parkinsonian and dyskinetic motor symptoms and (ii) the chronic low dose (CLD) MPTP-treated macaque model of cognitive (working memory and attentional) deficits. Behavioural analyses in l-DOPA-primed MPTP-treated macaques showed that istradefylline alone specifically alleviated postural deficits. When combined with an optimal l-DOPA treatment dose, istradefylline increased on-time, enhanced therapeutic effects on bradykinesia and locomotion, but exacerbated dyskinesia. Istradefylline treatment at specific doses with sub-optimal l-DOPA specifically alleviated bradykinesia. Cognitive assessments in CLD MPTP-treated macaques showed that the attentional and working memory deficits caused by l-DOPA were lowered after istradefylline administration. Taken together, these data support a broader clinical use of istradefylline as an adjunct treatment in PD, where specific treatment combinations can be utilised to manage various l-DOPA-induced complications, which importantly, maintain a desired anti-parkinsonian response.

RESUMEN

OBJECTIVE: In primary care populations in Western countries, high somatic symptom severity (SSS) and low quality of life (QoL) are associated with adverse psychobehavioural characteristics. This study assessed the relationship between SSS, QoL and psychobehavioural characteristics in Chinese general hospital outpatients. METHODS: This multicentre cross-sectional study enrolled 404 patients from 10 outpatient departments, including Neurology, Gastroenterology, Traditional Chinese Medicine [TCM] and Psychosomatic Medicine departments, in Beijing, Shanghai, Chengdu and Kunming. A structured interview was used to assess the cognitive, affective and behavioural features associated with somatic complaints, independent of their origin. Several standard instruments were used to assess SSS, emotional distress and health-related QoL. Patients who reported low SSS (PHQ-15<10, n=203, SOM-) were compared to patients who reported high SSS (PHQ-15≥10, n=201, SOM+). RESULTS: As compared to SOM- patients, SOM+ patients showed significantly more frequently adverse psychobehavioural characteristics in all questions of the interview. In hierarchical linear regression analyses adjusted for anxiety, depression, gender and medical conditions (SSS additionally for doctor visits), high SSS was significantly associated with "catastrophising" and "illness vulnerability"; low physical QoL was associated with "avoidance of physical activities" and "disuse of body parts"; low mental QoL was associated with "need for immediate medical help." CONCLUSION: In accordance with the results from Western countries, high SSS was associated with negative illness and self-perception, low physical QoL with avoidance behaviour, and low mental QoL with reassurance seeking in Chinese general hospital outpatients.

RESUMEN

In western countries, negative illness perceptions are associated with poor health status and affect health outcomes in primary care populations. The aim of this study is to examine the relationship between illness perception and mental and physical health status in general hospital outpatients in China. This multicentre, cross-sectional study analysed a total of 281 consecutive patients from four general hospital outpatient departments of internal medicine and traditional Chinese medicine in Beijing and Kunming. The patients answered questionnaires concerning illness perception (Brief-IPQ), somatic symptom severity (Patient Health Questionnaire-15), illness behaviour (Scale for the Assessment of Illness Behaviour), emotional distress (Hospital Anxiety and Depression Scale) and health-related quality of life (Twelve-Item Short Form Health Survey). Negative illness perception, especially negative emotional reactions, perceived illness consequences, encumbering illness concerns, and strong illness identity were significantly associated with high emotional distress, impairing illness consequences, and a low mental and physical quality of life. Using a multiple linear regression model, five strongest correlates of negative illness perception were high anxiety, seeking diagnosis verification, low mental and physical quality of life and high somatic symptom severity. The variance explained by this model was 35%. Chinese general hospital outpatients showed associations between negative illness perceptions and poor mental and physical health status that were similar to those of primary care patients in western countries. The main difference was that no association with perceived illness control was found in Chinese patients. Chinese physicians should be sensitised to their patients' negative illness perceptions and should focus on helping patients cope with uncertainty and anxiety by providing an understandable illness model and increasing control beliefs.

RESUMEN

OBJECTIVE: In high-income countries, the number and severity of somatic symptoms - irrespective of etiology--are associated with adverse psychobehavioral and functional characteristics. This study aimed to assess these key features among Chinese general hospital outpatients with high levels of somatic symptoms. METHODS: This multicenter, cross-sectional study evaluated four outpatient departments of internal medicine and Traditional Chinese Medicine in Beijing and Kunming and enrolled a total of 281 consecutive patients. The patients answered questionnaires concerning somatic symptom severity [Patient Health Questionnaire (PHQ-15)], illness perception (Brief Illness Perception Questionnaire), illness behavior (Scale for the Assessment of Illness Behavior), emotional distress (Hospital Anxiety and Depression Scale) and health-related quality of life (12-Item Short Form Health Survey). Subsamples reporting high scores of somatic symptom severity (PHQ-15 ≥10, SOM+) versus low scores (PHQ-15 <10, SOM-) were compared. RESULTS: Twenty-eight percent (79/281) of all outpatients showed high somatic symptom severity. The strongest correlations between high somatic symptom severity and psychobehavioral variables were found for high emotional distress, female gender, living alone, low physical quality of life and high dysfunctional illness behavior. The proportion of the explained variance was 36.1%. CONCLUSION: In Chinese outpatients, high somatic symptom severity is frequent and associated with psychobehavioral characteristics. With the PHQ-15 cutoff of 10, SOM+ patients could be differentiated from SOM- patients using these characteristics.

RESUMEN

It is indicated that there are important molecules interacting with brain nervous systems to regulate feeding and energy balance by influencing the signaling pathways of these systems, but relatively few of the critical players have been identified. In the present study, we provide the evidence for the role of Abelson helper integration site 1 (Ahi1) protein as a mediator of feeding behavior through interaction with serotonin receptor 2C (5-HT(2C)R), known for its critical role in feeding and appetite control. First, we demonstrated the co-localization and interaction between hypothalamic Ahi1 and 5-HT(2C)R. Ahi1 promoted the degradation of 5-HT(2C)R through the lysosomal pathway. Then, we investigated the effects of fasting on the expression of hypothalamic Ahi1 and 5-HT(2C)R. Fasting resulted in an increased Ahi1 expression and a concomitant decreased expression of 5-HT(2C)R. Knockdown of hypothalamic Ahi1 led to a concomitant increased expression of 5-HT(2C)R and a decrease of food intake and body weight. Last, we found that Ahi1 could regulate the expression of neuropeptide Y and proopiomelanocortin. Taken together, our results indicate that Ahi1 mediates feeding behavior by interacting with 5-HT(2C)R to modulate the serotonin signaling pathway.

RESUMEN

Several studies have reported associations between catechol-O-methyltransferase (COMT) gene Val158Met polymorphism and P300 event-related potentials in schizophrenic patients. But there has been no research to study the association between the P300 component and the Val158Met polymorphism in Chinese Han schizophrenia patients. Therefore, the present article was aimed at investigating the relationship of the Val158Met polymorphism with P300 in Chinese schizophrenic patients. The Val158Met polymorphism was detected by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in 287 schizophrenia patients and 84 healthy control subjects. P300 recordings were obtained in a subsample. A significant difference was not observed between the patients and control subjects in the genotype distributions and allele frequencies. P300 amplitude in schizophrenia patients was significantly lower than that of controls. The P300 latency in schizophrenia patients was also significantly longer than that of controls. The P300 latency of Met homozygotes was significantly shorter than that of Val/Met and of Val/Val carriers at Cz and Pz. The latency of Val/Met carriers was significantly shorter than that of Val/Val carriers at Pz. The results did not suggest an association between the polymorphism in the COMT gene and susceptibility to schizophrenia in the Chinese Han population.
