Braid stability after flow diverter treatment of intracranial aneurysms: a systematic review and meta-analysis

Review

作者: Saatci, Isil ; Hanel, Ricardo A ; Lylyk, Ivan ; Mendes Pereira, Vitor ; Lamin, Saleh ; Gounis, Matthew J ; Vivanco-Suarez, Juan ; Rice, Hal ; Rodriguez-Calienes, Aaron ; Lylyk, Pedro ; Fiehler, Jens ; Baltacioglu, Feyyaz ; Dibas, Mahmoud ; Cekirge, H Saruhan ; Fiorella, David ; Ortega-Gutierrez, Santiago

Background:

The aim of this study was to evaluate the overall rates of braid changes associated with flow diverter (FD) treatment for intracranial aneurysms (IAs). Additionally, we sought to provide an overview of the currently reported definitions related to these complications.

Methods:

A systematic search was conducted from the inception of relevant literature up to April 2023, encompassing six databases. The included studies focused on patients with IAs treated with FDs. We considered four main outcome measures as FD braid changes: (1) fish-mouthing, (2) device braid narrowing, (3) device braid collapsing, and (4) device braid deformation. The data from these studies were pooled using a random-effects model.

Results:

A total of 48 studies involving 3572 patients were included in the analysis. Among them, 14 studies (39%) provided definitions for fish-mouthing. However, none of the included studies offered specific definitions for device braid narrowing, collapsing, or deformation, despite reporting rates for these complications in six, five, and three studies, respectively. The pooled rates for braid changes were as follows: 3% (95% CI 2% to 4%, I2=27%) for fish-mouthing, 7% (95% CI 2% to 20%, I2=85%) for narrowing, 1% (95% CI 0% to 3%, I2=0%) for collapsing, and 1% (95% CI 1% to 4%, I2=0%) for deformation.

Conclusion:

The findings of this study suggest that FD treatment for IAs generally exhibits low rates of fish-mouthing, device braid narrowing, collapsing, and deformation. However, the lack of standardized definitions hinders the ability to compare device outcomes objectively, emphasizing the need for uniform definitions for FD braid changes in future prospective studies on FD.

Guanylate Kinase 1 Deficiency: A Novel and Potentially Treatable Mitochondrial DNA Depletion/Deletions Disease

Article

Objective:

Mitochondrial DNA (mtDNA) depletion/deletions syndrome (MDDS) comprises a group of diseases caused by primary autosomal defects of mtDNA maintenance. Our objective was to study the etiology of MDDS in 4 patients who lack pathogenic variants in known genetic causes.

Methods:

Whole exome sequencing of the probands was performed to identify pathogenic variants. We validated the mitochondrial defect by analyzing mtDNA, mitochondrial dNTP pools, respiratory chain activities, and GUK1 activity. To confirm pathogenicity of GUK1 deficiency, we expressed 2 GUK1 isoforms in patient cells.

Results:

We identified biallelic GUK1 pathogenic variants in all 4 probands who presented with ptosis, ophthalmoparesis, and myopathic proximal limb weakness, as well as variable hepatopathy and altered T‐lymphocyte profiles. Muscle biopsies from all probands showed mtDNA depletion, deletions, or both, as well as reduced activities of mitochondrial respiratory chain enzymes. GUK1 encodes guanylate kinase, originally identified as a cytosolic enzyme. Long and short isoforms of GUK1 exist. We observed that the long isoform is intramitochondrial and the short is cytosolic. In probands’ fibroblasts, we noted decreased GUK1 activity causing unbalanced mitochondrial dNTP pools and mtDNA depletion in both replicating and quiescent fibroblasts indicating that GUK1 deficiency impairs de novo and salvage nucleotide pathways. Proband fibroblasts treated with deoxyguanosine and/or forodesine, a purine phosphatase inhibitor, ameliorated mtDNA depletion, indicating potential pharmacological therapies.

Interpretation:

Primary GUK1 deficiency is a new and potentially treatable cause of MDDS. The cytosolic isoform of GUK1 may contribute to the T‐lymphocyte abnormality, which has not been observed in other MDDS disorders. ANN NEUROL 2024;96:1209–1224

Two year follow-up of distal unruptured intracranial aneurysms treated with a surface modified flow diverter under prasugrel monotherapy

Article

作者: Freitas, Rafael Kiyuze ; Machado, João Paulo ; Abud, Daniel Giansante ; Nakiri, Guilherme Seizem ; Monsignore, Lucas Moretti ; Abud, Thiago Giansante ; Colli, Benedicto Oscar ; de Oliveira, Ricardo Santos ; de Castro-Afonso, Luis Henrique

Background:

A new generation of modified surface flow diverters (FDs) and monotherapy using new antiplatelets may reduce both ischemic and hemorrhagic complications during the treatment of intracranial aneurysms. Previous preliminary safety analysis of distal unruptured intracranial aneurysms treated with the FD p48 MW HPC (phenox-Wallaby, Bochum, Germany) under antiplatelet monotherapy with prasugrel showed promising results. However, the long term outcomes of distal intracranial aneurysms treated with FDs under antiplatelet monotherapy are not known.

Methods:

This was a single center, prospective, pivotal, open single arm study. The primary (safety) endpoint was absence of any new neurological deficits after treatment until the 24 month follow-up. The primary (efficacy) endpoint was the incidence of complete aneurysm occlusion 24 months after treatment. The secondary (efficacy) endpoints were any incidence of aneurysm dome reduction 24 months after treatment.

Results:

21 patients harboring 27 distal aneurysms of the anterior circulation were included. No patient had neurologic deficits in the time from treatment to the 24 month follow-up. Complete aneurysm occlusion occurred in 20 (74%) of 27 aneurysms at the 24 month follow-up. Four aneurysms (14.8%) had dome reduction, and three aneurysms (11.1%) remained unchanged.

Conclusions:

In this pilot trial, treatment of distal unruptured intracranial aneurysms with an FD under monotherapy with prasugrel, followed by monotherapy with aspirin, appeared to be safe and effective. Randomized studies with long term follow-up are needed to confirm these results.

BJP：急性T淋巴细胞白血病的发病机制及靶向药物的研究进展

急性淋巴细胞性白血病(ALL)是一种恶性增殖的淋巴样细胞，早期分化受阻。淋巴细胞的异常增殖会在骨髓中积聚，并抑制正常的造血功能。成人ALL在确诊时往往有更高的风险因素，并有更多的共病。急性淋巴细胞性白血病(ALL)是一种恶性增殖的淋巴样细胞，早期分化受阻。淋巴细胞的异常增殖会在骨髓中积聚，并抑制正常的造血功能。成人ALL在确诊时往往有更高的风险因素，并有更多的共病。在T-ALL发病期间，淋巴细胞的异常增殖会破坏正常的免疫反应，扰乱免疫系统的功能。患者可能会出现药物不良反应(ADR)，如发热、体重意外减轻、盗汗、感染、出血和中枢神经系统(CNS)受累。在癌症治疗过程中，这些严重的并发症甚至可能危及患者的生命。图片来源：https://pubmed-ncbi-nlm-nih-gov.libproxy1.nus.edu.sg/36623836/ 近日，来自安徽医科大学的研究者们在Br J Pharmacol杂志上发表了题为“The pathogenesis and development of targeted drugs in acute T lymphoblastic leukemia”的综述性文章，在这篇综述中，研究者旨在介绍T-ALL病因学中最新和最经典的信号通路，并阐明T-ALL治疗的潜在靶向药物。急性淋巴细胞白血病(ALL)按其淋巴细胞来源主要分为急性T淋巴细胞白血病(T-ALL)和急性B淋巴细胞白血病(B-ALL)。其中，成人T-ALL的发病率约占成人ALL的25%，但恶性程度高，治愈率和预后差。现阶段针对T-ALL的靶向药物很少，常用的广谱化疗药物疗效差、不良反应多。了解T-ALL的发病机制，寻找介入治疗的发病机制，对于进一步开发新的T-ALL靶向药物和改进现有药物具有重要意义。信号通路异常是T的主要致病因素，在促进肿瘤的发生、发展、药物设计和治疗反应等方面起着至关重要的作用。这主要是因为信号通路在许多细胞生物学过程中是不可或缺的，包括肿瘤的生长、迁移、侵袭、转移等。因此，针对信号通路主要蛋白的小分子抑制剂受到了广泛的关注，并在临床前模型和临床试验中得到了开发和评估。已经上市的药物也正在作为联合疗法开发，以进一步提高疗效和克服肿瘤细胞耐药性。传统抗癌药物与靶向抗癌药物利弊比较图片来源：https://pubmed-ncbi-nlm-nih-gov.libproxy1.nus.edu.sg/36623836/ 本文综述了目前的研究现状，阐明信号通路异常是T-ALL发病机制中的关键因素，也是T-ALL治疗的关键。Forodesine、Nelarabine、ruxolitinib、cerulatinib、everolimus和temsirolimus等药物是公认的治疗白血病的抗癌药物，用于治疗ALL、AML和复发/难治性套细胞淋巴瘤。唯一已被批准上市并明确指明用于治疗T-ALL的药物是奈拉滨。总而言之，靶向治疗是个性化癌症医学的核心，并促进了诊断。靶向药物在T-ALL治疗中的应用仍然是一个困难的挑战，需要更多的关注。（生物谷 Bioon.com）参考文献 Zhaoying Chen et al.
