To review the evidence and determine the factors influencing the effect of mindfulness-based interventions (MBI) on diabetes distress. A systematic search of nine databases (PubMed, Cochrane Library, Web of Science, PsycINFO, Embase, China Knowledge Resource Integrated, VIP Data, SinoMed Data, and Wan Fang Data) was conducted. Randomized controlled trials of MBIs for adults with diabetes that evaluated the effect of the interventions on diabetes distress were retrieved. Meta-analysis was conducted by using Review Manager V.5.3, a Cochrane Collaboration tool. Subgroup analyses were conducted for exploring factors influencing the effect of MBIs on diabetes distress. A total of 10 articles, consisting of eight studies with 649 participants, were included. The results from subgroup analyses on the studies revealed five factors that influenced the effect of MBIs on diabetes distress compared with control group. Participants with elevated baseline diabetes distress showed a moderate effect size of 0.48 of decreasing diabetes distress when receiving MBIs (p=0.005); the MBIs based on mindfulness-based stress reduction therapy alleviated diabetes distress of the participants with a large effect size of 0.58 (p<0.0001); the MBIs delivered in group format decreased the diabetes distress with a moderate effect size of 0.36 (p=0.03); the MBIs with home practice assignment alleviated the diabetes distress with a moderate effect size of 0.42 (p=0.05). The long-term rather than short-term effect of MBIs on diabetes distress reduction has been identified with large effect size of 0.56 (p=0.04). MBIs improve outcomes in adults with diabetes who have elevated diabetes distress at baseline, using mindfulness-based stress reduction therapy, using a group format to deliver the intervention, and assigning home practice. MBIs improve diabetes distress significantly more at long-term follow-up compared with short-term follow-up. MBIs could be considered as an adjunct treatment in adults with diabetes to reduce diabetes distress.

Background: The primary aim of this study was to determine the efficacy of a psychological nursing intervention for improving sleep quality and alleviating anxiety and depression among hypopharyngeal carcinoma patients undergoing surgical resections.Methods: A total of 140 hypopharyngeal carcinoma patients undergoing surgical resections in our hospital from January 2017 to December 2020 were included and randomly assigned to a standard nursing group or psychological nursing group, with 70 cases per group. Sleep quality was assessed using the Pittsburgh sleep quality index (PSQI). The severity of anxiety symptoms and depressive disorders were evaluated using Zung's self-rating anxiety scale (SAS) and self-rating depression scale (SDS). The functional assessment of cancer therapy-general scale (FACT-G) tool was used to evaluate the quality of life. Fear of progression (FoP) was also scored.Results: Participants with hypopharyngeal carcinoma in the psychological nursing group demonstrated greater improvements in the primary outcome of global sleep quality (P=0.002) at postintervention compared to the participants in the standard nursing group. The psychological nursing group participants showed remarkably greater improvements in the subscale scores of global sleep quality characteristics (secondary outcomes) including daytime dysfunction (P<0.001), subjective sleep quality (P=0.029), and sleep latency (P=0.006) at postintervention compared to those receiving standard nursing. Psychological nursing group participants had lower SAS and SDS scores compared to those in the standard nursing group (P<0.001).The results revealed that participants who received psychological nursing intervention exhibited higher scores of all FACT-G subscales and lower scores of FoP compared to participants receiving standard nursing intervention (both P<0.001). The global sleep quality scores shared positive associations with scores of SAS, SDS, and FoP (r=0.518, r=0.572, and r=0.395, respectively, P<0.001).Conclusions: These data provide evidence that home-based psychological nursing intervention could improve sleep quality and alleviate anxiety and depression among hypopharyngeal carcinoma patients undergoing surgical resections.
