Non-Pharmacological Interventions to Improve Physical Function in Patients with End-Stage Renal Disease: A Network Meta-Analysis.

INTRODUCTION: Chronic kidney disease is estimated to become the fifth leading cause of death globally by 2040. Due to the high incidence of fatigue in patients with end-stage renal disease without reliable pharmacological treatments, more and more studies on non-pharmacological interventions to improve physical function appear; which might be the best approach remains unknown. This study aimed to compare and rank the efficacy of all known non-pharmacological interventions on improving physical function from multiple outcomes for adults with end-stage renal disease. METHODS: This systematic review and network meta-analysis included searches of PubMed, Embase, CINAHL, and Cochrane Library from inception to September 1, 2022, for randomized controlled trials of non-pharmacological interventions to improve physical function in adults with end-stage renal disease. Literature screening, data extraction, and quality appraisal were performed systematically by two independent reviewers. The frequentist random-effect network meta-analysis was adopted to pool the evidence from five outcomes, namely, 6-min walk test, handgrip strength, knee extension strength, physical component summary, and mental component summary, respectively. RESULTS: A total of 1,921 citations were identified by this search, of which 44 eligible trials enrolled 2,250 participants, and 16 interventions were identified. All subsequent figures refer to comparisons with usual care. For increasing walking distance, the combined resistance and aerobic exercise with virtual reality or music were the most effective interventions, with a mean difference plus 95% confidence interval of 90.69 (8.92-172.46) and 92.59 (23.13-162.06), respectively. Resistance exercise with blood flow restriction (8.13, 0.09-16.17) was the best treatment to improve handgrip strength. Combined resistance and aerobic exercise (11.93, 3.63-20.29) and whole-body vibration (6.46, 1.71-11.20) were associated with improving knee extension strength. For life quality, all treatment effects did not show statistically significant differences. CONCLUSIONS: It was found via network meta-analysis that combined resistance and aerobic exercise is the most effective intervention. Besides, if virtual reality or music is added to the training, there will be better results. Resistance exercise with blood flow restriction and whole-body vibration might be good alternative treatments for improving muscle strength. None of the interventions improved quality of life, suggesting a need for alternative interventions in this regard. The results of this study contribute evidence-based data to decision-making.

Does aquatic physical therapy affect the rehabilitation of breast cancer in women? A systematic review and meta-analysis of randomized controlled trials.

To determine and evaluate the benefits of aquatic physical therapy as a rehabilitation strategy for women with breast cancer on health outcomes. Electronic databases including PubMed, Web of Science, Embase, Cochrane Library and China National Knowledge Infrastructure (CNKI), Weipu (VIP) and Wanfang database were systematically searched until June 2021. Randomized controlled trials were included if they evaluated the effects of aquatic physical therapy in breast cancer patients. The quality of the trials included was assessed by the two independent researchers according to the Cochrane Collaboration Handbook recommendations. Outcome measures were fatigue, waist circumference and quality of life (QoL). The study was registered under PROSPERO (CRD42021157323). Totally, five studies comprising 356 participants were included in the study. Meta-analyses showed that aquatic physical therapy interventions significantly reduced the fatigue score (MD = -2.14, 95%CI: -2.82, -1.45, p<0.01) compared with usual care; In addition, we also observed that, compared with land-based exercise, aquatic physical therapy greatly improved the QoL (MD = 2.85, 95%CI: 0.62, 5.09, p = 0.01). However, aquatic physical therapy cannot improve physical index (waist circumference) compared to usual care (MD = -3.49, 95%CI: -11.56,4.58, p = 0.4). Consequently, aquatic physical therapy had a positive effect on the fatigue and QoL. The results of this meta-analysis can provide a reliable evidence for evaluating the interventional effectiveness of aquatic physical therapy.

A cross-sectional exploration of emergency department nurses' moral distress, ethical climate and nursing practice environment.

INTRODUCTION: Moral distress is a common phenomenon among nurses that leads to physical and emotional problems and affects job retention, job satisfaction, and quality of care. AIM: To explore relationships between moral distress, ethical climate, and nursing practice environment among a sample of ED nurses and determined significant predictors of moral distress in organizational environments. METHODS: A cross-sectional descriptive and correlational survey was performed on 237 nurses in emergency departments (EDs) from five hospitals in Taiyuan, mainland China. RESULTS: Statistically significant negative and moderate correlations were found between the level of moral distress and ethical climate for the overall evaluation and 10 subscale scores and the overall evaluation of the nursing practice environment. The nurse-physician collaboration, ethical climate, and monthly income were statistically significant predictors of the level of moral distress (change in R2 = 17.9%, 5.5%, and 5.6%, respectively). CONCLUSIONS: Perceptions of a more positive ethical climate and healthier nursing practice environment resulted in lower moral distress levels experienced by ED nurses. Poor nurse-physician collaboration is a pivotal factor accounting for ED nurses' moral distress.

Preparedness of Our Emergency Department During the Coronavirus Disease Outbreak from the Nurses' Perspectives: A Qualitative Research Study.

INTRODUCTION: This study explores the preparedness of our emergency department during the COVID-19 outbreak from the nurses' perspectives, providing a reference and basis for our emergency department's response to public health emergencies. METHODS: Using qualitative research methods, semistructured interviews were conducted with 12 emergency nurses who met the inclusion criteria, and Colaizzi analysis was used for data analysis, summary, and induction. RESULTS: A cluster of 4 themes that involved preparedness of the emergency department during the COVID-19 outbreak was extracted: organizational preparedness, personal preparedness, patient and family preparedness, and deficiencies and challenges. DISCUSSION: Organizations, individuals, patients, and family members were actively prepared to respond to novel coronavirus pneumonia outbreak in the emergency department. The emergency nurses said that the trusted organization guaranteed personal preparedness, and the active cooperation from patients and families was a motivator for personal preparedness. In addition, our study showed that there were deficiencies in both multidisciplinary collaboration efforts and efforts to rapidly diagnose and treat patients with fever in critical condition.

Long noncoding RNA LINC01234 silencing exerts an anti-oncogenic effect in esophageal cancer cells through microRNA-193a-5p-mediated CCNE1 downregulation.

BACKGROUND: Long non-coding RNAs (lncRNAs) are transcribed pervasively in the genome and act to regulate chromatin remodeling and gene expression. Dysregulated lncRNA expression has been reported in many cancers, but the role of lncRNAs in esophageal cancer (EC) has so far remained poorly understood. In this study, we aimed to understand the effect of lncRNA LINC01234 on EC development through competitively binding to microRNA-193a-5p (miR-193a-5p). METHODS: The Gene Expression Omnibus (GEO) database was used for microarray-based EC expression profiling. Gain- and loss-of-function analyses were carried out in human EC-derived Eca-109 and EC9706 cells. Expression analyses of miR-193a-5p, LINC01234, CCNE1, caspase-3, p21, Bax, cyclinD1 and Bcl-2 were performed using RT-qPCR and Western blotting. Cell proliferation, colony formation and apoptosis analyses were carried out using MTT, Hoechst 33258 and flow cytometry assays. A xenograft EC model in nude mice was used to evaluate in vivo tumor growth and CCNE1 expression. RESULTS: Microarray-based analyses revealed that LINC01234 expression was increased in primary EC samples, whereas that of miR-193a-5p was decreased. We found that CCNE1 was a target of miR-193a-5p and that LINC01234, in turn, sponges miR-193a-5p. After treatment with si-LINC01234 or miR-193a-5p mimic, EC cells (Eca-109 and EC9706) exhibited cyclinD1 and Bcl-2 downregulation, and caspase-3, p21, Bax and cleaved caspase-3 upregulation. LINC01234 silencing or miR-193a-5p upregulation resulted in decreased proliferation and colony formation, and increased apoptosis of EC cells. In addition, LINC01234 silencing or miR-193a-5p upregulation resulted in reduced in vivo EC tumor growth and CCNE1 expression in nude mice. CONCLUSIONS: We found that silencing of LINC01234 suppresses EC development by inhibiting CCNE1 through competitively binding to miR-193a-5p, which suggests that LINC01234 may represent a novel target for EC therapy.
