Effects of physical exercise on the quality-of-life of patients with haematological malignancies and thrombocytopenia:A systematic review and meta-analysis

BACKGROUND Annually,there are an estimated 1187000 new patients worldwide diagnosed with haematological malignancies.Effective strategies are needed to alleviate side effects and prevent the physical and psychosocial degeneration of patients in active treatment for haematological malignancies.AIM To explore the effects of physical exercise on quality of life(Qo L)of patients with haematological malignancies and thrombocytopenia.METHODS Cochrane Library,Pub Med and Embase were searched for all relevant articles reporting randomized controlled trials(RCTs)that were published up to 31 July 2021.Two authors independently selected articles in accordance with the inclusion criteria,evaluated their quality,and collected information.Any controversy was resolved through discussion with a third senior author.The PRISMA 2009 checklist was followed.RESULTS Seven RCTs were selected in the systematic review and three were included in the final meta-analysis.There were significant differences in Qo L between physical exercise groups[mean score difference=8.81;95%confidence interval(CI):1.81-15.81,P=0.01],especially in emotional functioning(mean score difference=12.34;95%CI:4.64-20.04,P=0.002)and pain(mean score difference=–12.77;95%CI:-3.91 to-21.63,P=0.005).CONCLUSION Physical exercise has clinical effects on Qo L and improves emotional function and pain indices of patients with haematological malignancies and thrombocytopenia.

Advancing the understanding and management of blastic plasmacytoid dendritic cell neoplasm:Insights from recent case studies

We specifically discuss the mechanisms of the pathogenesis,diagnosis,and management of blastic plasmacytoid dendritic cell neoplasm(BPDCN),a rare but aggressive haematologic malignancy characterized by frequent skin manifestations and systemic dissemination.The article enriches our understanding of BPDCN through detailed case reports showing the clinical,immunophenotypic,and histopathological features that are critical for diagnosing this disease.These cases highlight the essential role of pathologists in employing advanced immunophenotyping techniques to accurately identify the disease early in its course and guide treatment decisions.Furthermore,we explore the implications of these findings for management strategies,emphasizing the use of targeted therapies such as tagraxofusp and the potential of allogeneic haematopoietic stem cell transplantation in achieving remission.The editorial underscores the importance of interdisciplinary approaches in managing BPDCN,pointing towards a future where precision medicine could significantly improve patient outcomes.

Chinese Medicine Regulates DNA Methylation to Treat Haematological Malignancies:A New Paradigm of"State-Target Medicine"

Aberrant regulation of DNA methylation plays a crucial causative role in haematological malignancies(HMs).Targeted therapy,aiming for DNA methylation,is an effective mainstay of modem medicine;however,many issues remain to be addressed.The progress of epigenetic studies and the proposed theory of"state-target medicine"have provided conditions to form a new treatment paradigm that combines the"body state adjustment"of CM with targeted therapy.We discussed the correlation between Chinese medicine(CM)syndromes/states and DNA methylation in this paper.Additionally,the latest research findings on the intervention and regulation of DNA methylation in HMs,including the core targets,therapy status,CM compounds and active components of the Chinese materia medica were concisely summarized to establish a theoretical foundation of"state-target synchronous conditioning"pattern of integrative medicine for HMs,simultaneously leading a new perspective in clinical diagnosis and therapy.
