ABSTRACT
Objective@#Patients with late life depression sometimes refuse to receive electroconvulsive therapy (ECT) owing to its adverse reactions. To alleviate patient’s resistance, a novel ECT stimulation strategy named mixed-strategy ECT (msECT) was designed in which patients are administered conventional ECT during the first three sessions, followed by low energy stimulation during the subsequent sessions. However, whether low energy electrical stimulation in the subsequent stage of therapy affect its efficacy and reduce adverse reactions in patients with late life depression remains unknown. To explore differences between msECT and regular ECT(RECT) with respect to clinical efficacy and side effects @*Methods@#This randomized, controlled trial was conducted from 2019 to 2021 on 60 patients with late life depression who were randomly assigned to two groups: RECT or msECT. A generalized estimating equation (GEE) was used to compare the two stimulation strategies regarding their efficacy and side effects on cognition. Chi-squared test was used to compare side effects in the two strategies. @*Results@#In the intent-to-treat group, the GEE model suggested no differences between-group difference in Hamilton Depression Rating Scale-17 score over time (Wald χ2=7.275, p=0.064), whereas the comparison of side effects in the two strategies favored msECT (Wald χ2=8.463, p=0.015) as fewer patients had adverse events during the second phase of treatment with msECT (χ2 =13.467, p=0.004). @*Conclusion@#msECT presents its similar efficacy to RECT. msECT may have milder side effects on cognition.
ABSTRACT
AIM: To compare the visual quality in patients after implantation of extended-range-of-vision(Tecnis Symfony)intraocular lens(IOL)and zonal refractive(Lentis Comfort LS-313 MF15)IOL. METHODS: A prospective clinical study. Collecting 267 cataract patients(305 eyes)who underwent phacoemulsification combined with IOL implantation surgery in our hospital from January 2021 to December 2021,they were divided into the Symfony group(group A, 160 eyes)and MF15 group(group B, 145 eyes)according to the types of implanted IOL. Postoperative visual acuity were observed at 3mo and included uncorrected distance visual acuity(UDVA, 5m), uncorrected intermediate visual acuity(UIVA, 80 cm), uncorrected near visual acuity(UNVA, 40cm), defocus curve, modulation transfer function(MTF)and high-order aberrations(HOAs), including coma, spherical aberration and trefoil aberration, and conducted the Quality of Vision(QoV)questionnaire.RESULTS: There were no significant differences in the preoperative parameters in both groups(P>0.05). There was no significant difference between the UDVA and UNVA in groups A and B(P>0.05); The UIVA was higher in group A than in group B(P<0.05); The MTF value in group A was higher than group B at all spatial frequency, and the difference was statistical significant(P<0.05); The HOAs in group A was lower than that in group B(P<0.05); Defocus curves were plotted 3mo after the operation suggest that the visual acuity of the two groups was similar at 0D, and the visual acuity of the groups A was better than group B from -0.5D to -2.5D, and there was a statistically significant difference at -1.0D and -2.0D(P<0.05). The QoV score in group A was significantly higher than that in group B(P<0.05). The frequency of bad visual interference such as halo and starburst was higher in group A than in group B. CONCLUSION: Both the MF15 and Symfony can provide stable distance and near visual acuity. Compared with MF15, Symfony had better intermediate visual acuity, higher contrast sensitivity and lower HOAs. Compared with Symfony, MF15 IOL had less postoperative bad visual interference symptoms(halo, starburst, etc).

ABSTRACT
Background@#Necroptosis plays an important role in human atherosclerosis and atheroma development. Since receptor interacting protein kinase-3 (RIP3) acts as a key mediator of necroptosis, this study aimed to explore its relationship between plasma RIP3 levels and coronary artery disease (CAD) and discover a potential new biomarker for screening CAD subtypes and severity.@*Methods@#A total of 318 patients with CAD who had coronary angiography and 166 controls in Peking Union Medical College Hospital from September 2017 to January 2018 were enrolled in this study. Patients with CAD were divided into three subgroups: patients with stable coronary artery disease (SCAD), patients with unstable angina (UA), and patients with myocardial infarction (MI). The severity of atherosclerosis was determined by Gensini score (GSS). Logistic regression was used to determine the relationship between plasma RIP3 levels and CAD. The correlation between plasma RIP3 and GSS was calculated using multiple linear regression models.@*Results@#Overall, plasma RIP3 levels were significantly higher than serum RIP3 levels. Plasma RIP3 levels in patients with CAD were significantly higher than those in controls. Plasma RIP3 levels were strongly associated with CAD (odds ratio: 6.00, 95% confidence interval 3.04–11.81; P < 0.001). Plasma RIP3 levels increased linearly from controls to patients with SCAD, then patients with UA, and finally to patients with MI. We found a significantly positive correlation between proportion of cases of acute coronary syndrome in subjects and their plasma RIP3 level quartile. Plasma RIP3 levels were also associated with GSS (B 0.027; standard error 0.012; P < 0.05).@*Conclusions@#Plasma RIP3 levels were independently associated with CAD. Plasma RIP3 levels could potentially supplement clinical assessment to screen CAD and determine CAD severity.
ABSTRACT
Objective@#The purpose of this review is to stress the complicated interactions between the microbiota and the development of heart failure. Moreover, the feasibility of modulating intestinal microbes and metabolites as novel therapeutic strategies is discussed.@*Data sources@#This study was based on data obtained from PubMed up to March 31, 2019. Articles were selected using the following search terms: "gut microbiota," "heart failure," "trimethylamine N-oxide (TMAO)," "short-chain fatty acid (SCFA)," "bile acid," "uremic toxin," "treatment," "diet," "probiotic," "prebiotic," "antibiotic," and "fecal microbiota transplantation."@*Results@#Accumulated evidence has revealed that the composition of the gut microbiota varies obviously in people with heart failure compared to those with healthy status. Altered gut microbial communities contribute to heart failure through bacterial translocation or affecting multiple metabolic pathways, including the trimethylamine/TMAO, SCFA, bile acid, and uremic toxin pathways. Meanwhile, modulation of the gut microbiota through diet, pre/probiotics, fecal transplantation, and microbial enzyme inhibitors has become a potential therapeutic approach for many metabolic disorders. Specifically, a few studies have focused on the cardioprotective effects of probiotics on heart failure.@*Conclusions@#The composition of the gut microbiota in people with heart failure is different from those with healthy status. A reduction in SCFA-producing bacteria in patients with heart failure might be a notable characteristic for patients with heart failure. Moreover, an increase in the microbial potential to produce TMAO and lipopolysaccharides is prominent. More researches focused on the mechanisms of microbial metabolites and the clinical application of multiple therapeutic interventions is necessarily required.

<p><b>BACKGROUND</b>There has been no external validation of survival prediction models for severe adult respiratory distress syndrome (ARDS) with extracorporeal membrane oxygenation (ECMO) therapy in China. The aim of study was to compare the performance of multiple models recently developed for patients with ARDS undergoing ECMO based on Chinese single-center data.</p><p><b>METHODS</b>A retrospective case study was performed, including twenty-three severe ARDS patients who received ECMO from January 2009 to July 2015. The PRESERVE (Predicting death for severe ARDS on VV-ECMO), ECMOnet, Respiratory Extracorporeal Membrane Oxygenation Survival Prediction (RESP) score, a center-specific model developed for inter-hospital transfers receiving ECMO, and the classical risk-prediction scores of Acute Physiology and Chronic Health Evaluation (APACHE) II and Sequential Organ Failure Assessment (SOFA) were calculated. In-hospital and six-month mortality were regarded as the endpoints and model performance was evaluated by comparing the area under the receiver operating characteristic curve (AUC).</p><p><b>RESULTS</b>The RESP and APACHE II scores showed excellent discriminate performance in predicting survival with AUC of 0.835 (95% confidence interval [CI], 0.659-1.010, P = 0.007) and 0.762 (95% CI, 0.558-0.965, P = 0.035), respectively. The optimal cutoff values were risk class 3.5 for RESP and 35.5 for APACHE II score, and both showed 70.0% sensitivity and 84.6% specificity. The excellent performance of these models was also evident for the pneumonia etiological subgroup, for which the SOFA score was also shown to be predictive, with an AUC of 0.790 (95% CI, 0.571-1.009, P = 0.038). However, the ECMOnet and the score developed for externally retrieved ECMO patients failed to demonstrate significant discriminate power for the overall cohort. The PRESERVE model was unable to be evaluated fully since only one patient died six months postdischarge.</p><p><b>CONCLUSIONS</b>The RESP, APCHAE II, and SOFA scorings systems show good predictive value for intra-hospital survival of ARDS patients treated with ECMO in our single-center evaluation. Future validation should include a larger study with either more patients' data at single-center or by integration of domestic multi-center data. Development of a scoring system with national characteristics might be warranted.</p>
