RESUMO
Objective: Accumulating evidence indicates that inflammation abnormalities may contribute to aggression behaviors in psychotic patients, however, the possible sources of inflammation remain elusive. We aimed to evaluate the associations among aggression, inflammation, and bacterial translocation (BT) in aggression-affected schizophrenia (ScZ) inpatients with 2 weeks of antipsychotics discontinuation. Methods: Serum specimens collected from 112 aggression and 112 non-aggression individuals with ScZ and 56 healthy adults were used for quantifications of inflammation- or BT-related biomarkers. Aggression severity was assessed by Modified Overt Aggression Scale (MOAS). Results: Proinflammation phenotype dominated and leaky gut-induced BT occurred only in cases with ScZ with a history of aggression, and the MOAS score positively related to levels of C-reactive protein, interleukin (IL)-6, IL-1ß, and tumor necrosis factor-α. Furthermore, serum levels of BT-derived lipopolysaccharide (LPS), as well as LPS-responded soluble CD14, were not only positively correlated with levels of above proinflammation mediators but also the total MOAS score and subscore for aggression against objects or others. Conclusion: Our results collectively demonstrate the presence of leaky gut and further correlate BT-derived LPS and soluble CD14 to onset or severity of aggression possibly by driving proinflammation response in inpatients with ScZ, which indicates that BT may be a novel anti-inflammation therapeutic target for aggression prophylaxis.
RESUMO
AIMS: Over the past decade, catheter ablation (CA) has become an established therapy for symptomatic atrial fibrillation (AF). Atrial fibrillation is common in hypertrophic cardiomyopathy (HCM) patients, and restoring sinus rhythm is of great clinical benefit to them. Therefore, we conducted a systematic review and meta-analysis of the available data to evaluate the effectiveness and safety of CA for AF in patients with HCM. METHODS AND RESULTS: Six databases were searched to identify studies describing outcomes of CA of AF in HCM patients with a mean follow-up of ≥12 months after the index procedure. The following data were extracted: (i) single-procedure success, (ii) multiple-procedure success, and (iii) drug-free success. Fifteen studies involving 531 patients were included. Single-procedure freedom from atrial arrhythmia at the latest follow-up was 45.5% [95% confidence interval (CI): 34.8-56.2%]. With multiple procedures, the final success rate was 66.1% (95% CI: 55.3-76.9%) overall, 71.8% (95% CI: 61.6-82.0%) in paroxysmal AF, and 47.5% (95% CI: 36.0-59.0%) in non-paroxysmal AF. Without anti-arrhythmic drugs (AADs), single-procedure success rate at latest follow-up was 32.9% (95% CI: 21.7-41.1%); after multiple procedures, this raised to 50.4% (95% CI: 39.2-61.6%). The incidence of serious periprocedural complications was acceptable [5.1% (95% CI: 2.8-9.6%)]. Substantial heterogeneity (I(2)> 50%) was noted in the above groups. CONCLUSIONS: Catheter ablation of AF in patients with HCM is feasible, although more repeat procedures and AAD are needed to prevent AF recurrence.
