ABSTRACT

This meta-analysis was a systematic review of evidence on the effects of mindfulness-based stress reduction (MBSR) and mindfulness-based cognitive therapy (MBCT) on quality of life (QOL), pain, fatigue, anxiety, and depression in cancer patients. Until July 2020, PubMed, Cochrane Library, and Embase were searched for randomized controlled trials (RCTs). The study included 18 RCTs. The MBSR/MBCT intervention resulted in a significant effect on QOL (SMD 0.80, CI 0.28, 1.32, I2 = 94%). In subgroup analysis, MBSR/MBCT interventions had a significant effect in the early cancer stage on anxiety (SMD - 3.48, CI - 4.07, - 2.88), and QOL (SMD 4.30, CI 3.62, 4.99); in alleviating decreasing pain (SMD - 0.42, CI - 0.70, - 0.14) within 4 weeks after the end of intervention, and alleviating fatigue in younger participants (SMD - 0.64, CI - 1.09, - 0.19). MBSR/MBCT has short-term effects on cancer patients, especially in younger patients and early cancer stages.

ABSTRACT

The spindle checkpoint acts during cell division to prevent aneuploidy, a hallmark of cancer. During checkpoint activation, Mad1 recruits Mad2 to kinetochores to generate a signal that delays anaphase onset. Yet, whether additional factors contribute to Mad2's kinetochore localization remains unclear. Here, we report that the conserved AAA+ ATPase TRIP13(PCH-2) localizes to unattached kinetochores and is required for spindle checkpoint activation in Caenorhabditis elegans. pch-2 mutants effectively localized Mad1 to unattached kinetochores, but Mad2 recruitment was significantly reduced. Furthermore, we show that the C. elegans orthologue of the Mad2 inhibitor p31(comet)(CMT-1) interacts with TRIP13(PCH-2) and is required for its localization to unattached kinetochores. These factors also genetically interact, as loss of p31(comet)(CMT-1) partially suppressed the requirement for TRIP13(PCH-2) in Mad2 localization and spindle checkpoint signaling. These data support a model in which the ability of TRIP13(PCH-2) to disassemble a p31(comet)/Mad2 complex, which has been well characterized in the context of checkpoint silencing, is also critical for spindle checkpoint activation.
