ABSTRACT

OBJECTIVE: The relative effects of monoclonal antibody against calcitonin gene-related peptide (CGRP) or its receptor for adult migraine patients with prior treatment failure remains uncertain. Therefore, this study systematically assessed the comparative effectiveness of different CGRP binding monoclonal antibodies (mAbs) for these patients.

METHODS: Several online databases including Ovid MEDILNE, Ovid EMBASE, Cochrane Library, and ClinicalTrials.gov were systematically searched from inception to June 15, 2022. We included randomized clinical trials (RCT) of adult migraine patients with previous treatment failure that assessed any CGRP monoclonal antibody. The primary efficacy outcome was change in monthly migraine days (MMDs), and the primary safety outcome was treatment-emergent adverse events (TEAEs).

RESULTS: Overall, seven studies totaling 3, 052 patients were included. Three-node analysis showed that CGRP mAbs was superior to CGRP receptor mAbs in reducing MMDs (MD: -1.55, 95% CrI: - 2.43 to - 0.44) and improving at least 50% response rates (RR: 1.52, 95% CrI: 1.04 to 2.21). Nine-node analysis showed galcanezumab 240 mg ranked first in reducing MMDs (MD -4.40, 95% CrI - 7.60 to - 1.19) and improving 50% response rates (RR: 4.18, 95% CrI: 2.63 to 6.67). Moreover, treatment with fremanezumab or eptinezumab 300 mg provides a significant advantage over erenumab 140 mg regarding an improved response rate of at least 50%. The analysis did not show difference in incidences of TEAEs and serious adverse events in any of the comparisons.

CONCLUSIONS: It appears that CGRP mAbs, especially galcanezumab 240 mg, monthly fremanezumab, and eptinezumab 300 mg, seem to be the best choice for the treatment of migraine patients with previous treatment failures. This finding also calls for future research that examine the associations between these medications in migraine therapy among the same patient group to testify the present findings.

ABSTRACT

OBJECTIVE: Intracoronary injection of pro-urokinase (Pro-UK) during percutaneous coronary intervention (PCI) seems to be a promising treatment in improving myocardial perfusion. In this systematic review and meta-analysis, we aimed at investigating the efficacy and safety of intracoronary Pro-UK injection during PCI in ST elevation myocardial infarction (STEMI) patients.

MATERIALS AND METHODS: A comprehensive literature searched on PubMed, Embase, Cochrane, Ovid-MEDLINE, Ovid-Embase, Ovid-Cochrane Databases and ClinicalTrials.gov from inception until June 1, 2022, in English only. The primary outcome was myocardial perfusion, including thrombolysis in myocardial infarction (TIMI) grades, corrected TIMI frame count (CTFC), TIMI myocardial perfusion grades (TMPG). The secondary outcomes were ST-segment resolution (STR), major adverse cardiovascular events (MACE), myocardial marker, cardiac function and hemorrhagic complications.

RESULTS: We identified 5 studies (all RCTs) involving 761 participants. Under PCI procedure, compared with placebo, intracoronary Pro-UK injection may improve myocardial perfusion, including increasing the TIMI grades [odd ratio (OR) 0.46; 95% confidence interval (CI) 0.28-0.75; p = 0.002; I2 = 0%] , CTFC (OR -3.47; 95% CI [-5.60, -1.33]; p = 0.001; I2 = 0%) and TMPG (OR 0.17; 95% CI [0.06-0.44]; p = 0.0003; I2 = 0%), increase the rate of STR (OR 2.25; 95% CI [1.56-3.26]; p < 0.0001; I2 = 0%), reduce the incidence of MACE (OR 0.51; 95% CI [0.33-0.81]; p = 0.004; I2 = 0%) and reduce myocardial infarct size (CK, standardized mean difference [SMD] -0.45; 95% [CI] [-0.62, -0.28]; p < 0.00001; I2 = 10%. CK-MB, [SMD] -0.43; 95% CI [-0.68, -0.18]; p = 0.0007; I2 = 60%. cTnI, [SMD] -0.31; 95% CI [-0.46, -0.17]; p < 0.0001; I2 = 0%). Moreover, the treatment may improve the cardiac functions (LVFE, pooled mean difference [MD] 1.23; 95% CI [0.66-1.79]; p < 0.0001; I2 = 24%. LVEDd, pooled MD -0.13; 95% CI [-0.17, -0.09]; p < 0.00001; I2 = 0%). But there is no statistically significant difference between the Pro-UK group and placebo in the occurrence of hemorrhagic complications (OR 1.19; 95% CI [0.75-1.87]; p = 0.46; I2 = 0%).

CONCLUSIONS: Intracoronary Pro-UK injection during PCI in STEMI patients is an effective and safe treatment to perform. The treatment may improve myocardial perfusion and rate of STR, as well as decreasing the incidence of MACE and myocardial infarct size. Importantly, the treatment may improve the cardiac functions and life quality. In the future, more multi-centered and massive sample studies are required.

ABSTRACT

BACKGROUND: New-onset refractory status epilepticus (NORSE) has been reported in the scientific literature as a phenomenon associated with the COVID-19 infection. Given the resurgence of the newer variants of COVID-19 added with its multi-system manifestations, this project was conducted to study the clinical picture of NORSE secondary to COVID-19 infection.

METHODS: Three electronic databases were searched using an extensive search strategy from November 2019 to December 2021. Patients reporting NORSE secondary to COVID-19 were included in this review. The status epilepticus severity score (STESS) was calculated by the study authors for individual patients. Statistical analysis was performed using SPSS version 26 with a p-value <0.05 as statistically significant.

RESULTS: After screening, 12 patients were included in this study with a mean age of 61.6 ± 19.0-year olds. The most common type of status epilepticus reported in our study population was non-convulsive status epilepticus (NCSE) (7 out of 12 patients, 58.3%). The linear regression model revealed that STESS scores were significantly influenced by patients' age (p = 0.004) and intra-hospital occurrence (IHO) of status epilepticus (p = 0.026). Overall, 8 patients (66.7%) were discharged without complications.

CONCLUSION: Given the observed association of STESS with the aging population and IHO of status epilepticus, special attention is due to the caretakers of this population, while further studies are needed to further build upon this review.

ABSTRACT

BACKGROUND: Primary central nervous system lymphoma (PCNSL) and high-grade glioma (HGG) appear similar under imaging. However, since the two tumors vary in their treatment methods, their differential diagnosis is crucial. The use of 18F-fluorodeoxyglucose positron emission tomography computed tomography (18F-FDG-PET/CT) imaging to effectively distinguish between the two tumors is not clear; therefore, a meta-analysis was carried out to determine its effectiveness.

MATERIALS AND METHODS: The databases PubMed, EMBASE, Cochrane, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang, China Science, and Technology Journal Database (CQVIP) were exhaustively searched using stringent inclusion and exclusion criteria to select high-quality literature. The Quality Assessment Tool for Diagnostic Accuracy Studies (QUADAS-2) was used for the qualitative assessment of the included literature. The bivariate effect model was used to combine statistics such as sensitivity (SEN) and specificity (SPE), positive likelihood ratio (PLR), negative likelihood ratio (NLR), and diagnostic odds ratio (DOR) [95% confidence intervals (CI)], plot summary receiver operating characteristic (SROC) curve, and calculate the area under the curve (AUC) value. Sensitivity analysis was used to evaluate the stability of the results, and Deek's test was used to assess publication bias. Meta-regression and subgroup analysis was used to determine the sources of heterogeneity.

RESULTS: A total of nine studies were included in this study. For differential diagnosis of PCNSL and HGG, the combined SEN was 0.91 (95% CI: 0.80-0.96; I² = 46.73%), combined SPE was 0.88 (95% CI: 0.82-0.93; I² = 56.30%), the combined PLR was 7.83 (95% CI: 4.96-12.37; I² = 15.57%), combined NLR was 0.10 (95% CI: 0.05-0.23; I² = 31.99%), combined DOR was 77.36 (95% CI: 32.74-182.77; I² = 70.70%). The AUC of SROC was 0.95 (95% CI: 0.93-0.97). No publication bias was found and the sample size and different parameters were the primary reason for heterogeneity.

CONCLUSION: The 18F-FDG-PET/CT imaging technique has a high diagnostic accuracy in the differential diagnosis of PNCSL and HGG. Patients suspected to have the above two tumors are suggested to be examined by 18F-FDG-PET / CT to help in the clinical distinction and further treatment modalities.

ABSTRACT

There is an increasing number of trauma patients presenting on pre-injury antiplatelet (AP) agents attributable to an aging population and expanding cardio- or cerebrovascular indications for antithrombotic therapy. The effects of different AP regimens on outcomes after traumatic brain injury (TBI) have yet to be elucidated, despite the implications on patient/family counseling and the potential need for better reversal strategies. The goal of this systematic review and meta-analysis was to assess the impact of different pre-injury AP regimens on outcomes after TBI. In accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, the OVID Medline, Embase, BIOSIS, Scopus, and Cochrane databases were searched from inception to February 2022 using a combination of terms pertaining to TBI and use of AP agents. Baseline demographics and study characteristics as well as outcome data pertaining to intracerebral hematoma (ICH) progression, need for neurosurgical intervention, hospital length of stay, mortality, and functional outcome were extracted. Pooled odds ratios (ORs) and mean differences comparing groups were calculated using random-effects models. Thirteen observational studies, totaling 1244 patients receiving single AP therapy with acetylsalicylic acid or clopidogrel, 413 patients on dual AP therapy, and 3027 non-AP users were included. No randomized controlled trials were identified. There were significant associations between dual AP use and ICH progression (OR, 2.81; 95% confidence interval [CI], 1.19-6.61; I ², 85%; p = 0.02) and need for neurosurgical intervention post-TBI (OR, 1.61; 95% CI, 1.15-2.28; I ², 15%; p = 0.006) compared to non-users, but not between single AP therapy and non-users. There were no associations between AP use and hospital length of stay or mortality after trauma. Pre-injury dual AP use, but not single AP use, is associated with higher rates of ICH progression and neurosurgical intervention post-TBI. However, the overall quality of studies was low, and this association should be further investigated in larger studies.
