Adherence to the 'Atrial Fibrillation Better Care' Pathway in Patients with Atrial Fibrillation: Impact on Clinical Outcomes-A Systematic Review and Meta-Analysis of 285,000 Patients

Giulio Francesco Romiti, Daniele Pastori, Jose Miguel Rivera-Caravaca, Wern Yew Ding, Ying Xuan Gue, Danilo Menichelli, Jakub Gumprecht, Monika Koziel, Pil-Sung Yang, Yutao Guo, Gregory Y. H. Lip, Marco Proietti

Summary: A systematic review and meta-analysis of studies on the use of the ABC pathway in patients with atrial fibrillation showed suboptimal adherence at 21%, but adherence was associated with a lower risk of all-cause death, cardiovascular death, stroke, and major bleeding. Comorbidities and longer follow-up were identified as factors affecting heterogeneity and effectiveness of the pathway.

Jian Liu, Minyang Fu, Manni Wang, Dandan Wan, Yuquan Wei, Xiawei Wei

Summary: Research on tumor immunotherapy has made significant progress, and cancer vaccines have emerged as a promising therapeutic strategy. Cancer vaccines stimulate anti-tumor immunity with tumor antigens, potentially overcoming immune suppression and inducing both humoral and cellular immunity. This review introduces the working mechanism of cancer vaccines, summarizes different development platforms, and highlights their clinical research progress, with a focus on clinical application and therapeutic efficacy.

Lipoprotein(a): A Genetically Determined, Causal, and Prevalent Risk Factor for Atherosclerotic Cardiovascular Disease: A Scientific Statement From the American Heart Association

Summary: High levels of Lp(a) are an independent and causal risk factor for atherosclerotic cardiovascular diseases. Genetic factors determine 70% to 90% of interindividual heterogeneity in Lp(a) levels. There is a lack of standardized assays, diagnostic guidelines, and targeted treatments for lowering Lp(a). Understanding the genetic and biological basis for variation in Lp(a) levels in different populations is crucial.

Summary: In response to the COVID-19 pandemic, vaccines for SARS-CoV-2 were rapidly developed and introduced, leading to a major impact on the evolution of the disease. However, reports of rare side-effects such as vaccine-induced immune thrombotic thrombocytopenia (VITT) have emerged, requiring prompt testing and treatment with intravenous immunoglobulin and non-heparin anticoagulants.

Summary: Poststroke cognitive impairment and dementia is a common problem among stroke patients, influenced by factors such as age, education level, preexisting cognitive decline, and history of prior stroke. Manifestations of cerebral small vessel disease also contribute to cognitive outcomes. Understanding the interaction between acute stroke events and preexisting brain pathology is crucial for personalized prediction, prevention, targeted interventions, and rehabilitation.

Summary: This review discusses the role of exosomes in cancer progression, therapy, and regulation of the tumor microenvironment. The study found that exosomes can influence cancer cell proliferation and migration rates by modulating components of the tumor microenvironment. Depending on their cargo, exosomes can promote or suppress tumor cell progression and enhance or reduce the response to radiotherapy and chemotherapy. Additionally, exosomes can trigger chronic inflammation and lead to immune evasion and tumor progression by transferring RNA and modulating molecular signaling pathways. Moreover, exosomes can serve as carriers of anti-tumor agents and genetic tools to control cancer progression. Finally, exosomes are valuable diagnostic and prognostic tools in the treatment of cancer patients.

Improvement of the anticancer efficacy of PD-1/PD-L1 blockade via combination therapy and PD-L1 regulation

Mengling Wu, Qianrui Huang, Yao Xie, Xuyi Wu, Hongbo Ma, Yiwen Zhang, Yong Xia

Summary: PD-1/PD-L1 immune checkpoints inhibit the anticancer effect of T cells in the tumor microenvironment, and downregulation or upregulation of PD-L1 expression can improve the efficacy of anti-PD-1/PD-L1 treatment. Overcoming the current limitations of this treatment can expand its anticancer applications and improve patient response rates and survival time.

Summary: APR 246 is a promising therapeutic agent for myelodysplastic syndromes and acute myeloid leukemia that targets p53 mutated proteins. It has been found to reactivate the transcriptional activity of p53 mutants and induce p53-independent cell death. The study also demonstrates the association between APR 246 and ferroptosis, a recently described cell death process. The detoxification capacity of AML cells to maintain glutathione biosynthesis may play a key role in determining sensitivity to APR 246.

Summary: Antithrombotic agents, particularly heparins, are recommended for patients with COVID-19 to reduce thromboembolism risk. The optimal dosing and timing of these treatments, as well as the benefits of other antithrombotic agents, are still unclear. A panel of experts developed 12 recommendations based on high- to moderate-quality evidence, including the use of prophylactic or therapeutic dose heparin for different patient groups. Additional weak recommendations were made for the use of sulodexide, adding antiplatelet agents, and prophylactic rivaroxaban in select patients. Future updates will incorporate new evidence and may modify these recommendations.
