Importance The role and safety of transcranial electrical stimulation (tES) for treating depressive disorders remain under evaluation. Objective To evaluate tES treatment in patients with major depressive disorder (MDD) and comorbid depressive conditions. Data Sources A search of MEDLINE, Embase, Cochrane, APA PsycINFO, and Scopus databases was conducted from inception to September 17, 2024. Study Selection Randomized clinical trials (RCTs) of adults with MDD, depression with psychiatric comorbidities (DPC), or depression with medical comorbidities (DMC), treated with transcranial direct current stimulation (tDCS), transcranial alternating current stimulation (tACS), or transcranial random noise stimulation (tRNS), compared with sham or other treatments were included. Data Extraction and Synthesis Independent reviewers extracted data in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines, with random-effects meta-analysis used for pooling. Main Outcomes and Measures Primary outcomes were depression severity, response and remission rates, and adverse events. Standardized mean differences (SMDs) were reported for continuous outcomes, and odds ratios (ORs) were reported for categorical outcomes. Quality of evidence (QOE) was assessed using the Grading of Recommendations Assessment, Development, and Evaluation criteria. Results The meta-analysis included 5522 participants from 114 study groups from 88 RCTs (3198 female [58.9%]; mean [range] age, 43.1 [19.4-76.9] years). Most studies (104 study groups from 79 RCTs [91.2%]) evaluated tDCS, while 7 study groups from 6 RCTs (6.1%) evaluated tACS, and 3 study groups from 3 RCTs (2.7%) evaluated tRNS. tES was associated with reduced depressive symptoms (SMD = −0.59; 95% CI, −0.83 to −0.35; low QOE) and improvement in DMC (SMD = −1.05; 95% CI, −1.67 to −0.43; low QOE) and DPC (SMD = −0.78; 95% CI, −1.27 to −0.29; low QOE) compared with MDD (SMD = −0.22; 95% CI, −0.44 to 0.01; low QOE). tDCS was associated with reduced depression in DMC (SMD = −1.05; 95% CI, −1.70 to −0.40; very low QOE) and DPC (SMD = −0.88; 95% CI, −1.40 to −0.36; low QOE) but not MDD. tACS was associated with improved MDD symptoms (SMD = −0.58; 95% CI, −0.96 to −0.20; high QOE) and response rates (OR, 2.07; 95% CI, 1.34 to 3.19; high QOE). Combined tDCS and medication was associated with reduced symptoms (SMD = −0.51; 95% CI, −0.90 to −0.13; moderate QOE) and increased response (OR, 2.25; 95% CI, 1.08 to 4.65; high QOE) in MDD. tDCS combined with psychotherapy was not associated with improvement. Subgroup analysis showed that anodal left dorsolateral prefrontal cortex DCS was associated with improved outcomes. Mild to moderate adverse events were more frequent in tES groups. Conclusions and Relevance In this systematic review and meta-analysis, tDCS was associated with improvement in depression among patients with DMC and DPC (with smaller benefits in MDD), tACS was associated with improved MDD outcomes (while tRNS had insufficient evidence) in smaller samples, and combined tDCS and medication was associated with improvement in depression. These findings suggest that tES is well-tolerated overall, with only mild to moderate adverse events, and that future research should optimize stimulation parameters and individualize tES interventions.

Non-ST-segment elevation myocardial infarction (NSTEMI) can be managed by ischemia guide strategies or early invasive strategies. Here, we present the findings of an updated contemporary analysis regarding the use of intracoronary imaging (ICI)-guided PCI versus angiography-guided PCI and in-hospital mortality in patients with NSTEMI in the United States using the NIS database from 2016 to 2021. ICI use increased by nearly threefold between 2016 and 2021, without a significant difference in in-hospital mortality, though interestingly, mortality rates compared with angiography guidance were similar and relatively low. In this study, the use of ICI was associated with lower adjusted odds of in-hospital mortality, cardiogenic shock, and cardiac arrest, but with a longer length of stay and cost of hospitalization.

ABSTRACTBackgroundThe role of Intravascular ultrasound (IVUS) and optical coherence tomography (OCT) is still unclear in patients with STEMI undergoing PCI in the current second‐generation DES era.AimsThis study aimed to evaluate the trends and outcomes of IVUS‐guided PCI in patients with STEMI.MethodsWe used the National Inpatient Sample (NIS) database from 2016 to 2021. The primary endpoint of this study is all‐cause in‐hospital mortality. Secondary endpoints include trends of PCI hospitalizations, trends of mortality, length of stay, and cost of hospitalization.ResultsThere were data for 819,645 hospitalizations for STEMI, of which 91.2% (n = 74,7860) utilized angiography‐guided PCI, 8.4% (n = 68,985) utilized IVUS‐guided PCI and 0.3% (n = 2800) utilized OCT‐guided PCI. In‐hospital mortality for IVUS‐guided PCI was 4.6% (n = 3190) versus 6.0% (n = 44,935) for angiography‐guided PCI with an adjusted OR 0.75 (0.68–0.81, p < 0.001). In‐hospital mortality for OCT‐guided PCI was 3.4% (n = 95) versus 6.0% (n = 44,935) for angiography‐guided PCI with an adjusted OR 0.67 (0.43–1.06, p = 0.09).ConclusionsIVUS/OCT‐guidance was increasingly utilized over the years and was associated with a significantly reduced adjusted odds of in‐hospital mortality. Large‐scale, long‐term randomized data are needed to better ascertain where IVUS/OCT may be best utilized for optimization of PCI for STEMI.

Intravascular ultrasound (IVUS) and optical coherence tomography (OCT) have become increasingly utilized in patients undergoing percutaneous coronary intervention (PCI). Despite these purported advantages, prior reports regarding the use of IVUS and OCT have indicated that contemporary use of intravascular imaging remains low with significant regional variation. Here, we present the findings of an updated contemporary analysis regarding the use of IVUS/OCT-guided PCI versus angiography-guided PCI in the United States. We also evaluated in-hospital mortality and clinical outcomes between IVUS/OCT-guided PCI versus angiography-guided PCI-only over million patients in the United States. There has been a significant decrease in the number of PCIs performed, while there has been increasing in the trend of IVUS/OCT-guided PCI over this period. Most importantly, we found that IVUS/OCT-guided PCI was associated with better clinical outcomes in terms of in-hospital mortality, compared with angiography-guided PCI.
