Creative versus repetitive dance therapies to reduce the impact of fibromyalgia and pain: A systematic review and meta-analysis

Background and purposePhysical exercise is one of the most effective interventions to reduce fibromyalgia symptoms. Previous studies have reported benefits of dance-based intervention on the fibromyalgia impact, health-related quality of life and pain, regardless the interventions were based on creative- or repetitive dance. This study aimed to compare the effectiveness of creative and repetitive dance interventions.MethodsPRISMA guidelines were followed in this systematic review. The Cochrane Library, PubMed, Trip, Google Scholar, Web of Science (WOS), Embase and Scopus databases were selected to identify potential articles. Studies were included if they met the following inclusion criteria: to be a clinical trial or a randomized controlled trial, include people with fibromyalgia, have a comparison group and evaluate the impact of the disease, pain or quality of life. Fifteen articles fulfilled the inclusion criteria. The methodological quality of the studies was assessed using the Cochrane Collaboration's tool.ResultsDance-based interventions significantly reduced fibromyalgia impact (standardized mean difference = −0.69), pain (standardized mean difference = −0.70 and increased quality of life (standardized mean difference = 0.43) of people with fibromyalgia. The effectiveness of dance interventions is increased when a creative component is added, since it can lead to higher improvements in pain, impact of the disease and improving quality of life.ConclusionDance-based interventions are significantly effective in reducing the impact of fibromyalgia, pain as well as increasing health-related quality of life. Subgroup analyses suggest that creative dance-based interventions could be more effective than repetitive dance-based interventions to reduce pain and fibromyalgia impact. However, results must be taken with caution due to the large heterogeneity and the small number of articles.     

Involvement of the #12u lymph nodes around the upper lobe bronchi in patients with lung cancer of the right middle lobe, right lower lobe, or left lower lobe

Abtract In Japan, the lymph nodes around the upper lobe bronchi, known as the #12u nodes, are not included in the nodes recommended for dissection in patients with right middle lobe carcinoma, right lower lobe carcinoma, or left lower lobe carcinoma. However, histologic examination has revealed involvement of these nodes in pneumonectomy patients whose carcinoma originated in the right lower lobe. We histologically examined the lymph nodes from 152 patients with lung cancer to determine the incidence of involvement of the #12u lymph nodes. These nodes were found to be involved in 14 (9.2%) of the 152 patients. The rate of involvement was significantly higher in those with T2–T4 disease than in those with T1 disease, and was also significantly higher in patients with N2 disease than in those with N1 disease. There were two long-term survivors without recurrence, and one other patient who lived for more than 5 years before succumbing to the disease. In conclusion, to ensure removal of all the cancer tissue, it is recommended that the #12u lymph nodes be included in the nodes routinely dissected in patients with right lower lobe carcinoma, right middle lobe carcinoma, or left lower lobe carcinoma.     

谷氨酸转运体、谷氨酸/胱氨酸转运体与谷氨酸神经细胞毒作用

谷氨酸转运体与谷氨酸／胱氨酸转运体在脑缺血疾病中起重要作用，谷氨酸转运体的结构或功能改变可使细胞间隙的谷氨酸浓度急剧升高，激活NMDA受体产生一系列的表现，同时抑制谷氨酸／胱氨酸转运体对胱氨酸的摄取，介导谷胱苷肽耗竭、氧自由基升高、胞内钙升高、线粒体损伤、细胞色素c释放等神经细胞毒环节，激活半胱天冬酶诱导凋亡。可进一步加重谷氨酸的神经细胞毒作用。

A quality assessment tool to evaluate tocolytic studies

Over the past 15 years, the use of β-agonists has declined worldwide. Following the Royal College of Obstetricians and Gynaecologists guidelines in 2002, clinicians in the UK and beyond were faced with the dilemma of continuing to use β-agonists, desist from using tocolytic therapy completely or choosing to change to atosiban or calcium channel blockers (CCBs). While grade A level 1 evidence exists to show that atosiban is significantly more efficacious than placebo and significantly safer than β-agonists for the treatment of spontaneous preterm labour, the evidence for CCBs, such as nifedipine, is much less robust and no placebo-controlled trials have been performed. Published studies on nifedipine are largely investigator-led studies of small sample size, which lack sufficient power. As a result, most of the evidence has been based on meta-analyses of these studies, which look retrospectively at pooled data and are only as good as the quality of the studies included. In light of this, a tool was developed to produce a systematic review of studies on tocolytic effectiveness, which can and should be applied to all tocolytics and which considered both method- and topic-specific markers of quality. In the process of applying this tool to nifedipine, an extensive literature search identified 31 studies for a systematic review of the quality of nifedipine studies assessed by eight paired reviewers with wide experience in the subject of spontaneous preterm labour and preterm birth. Forty topic- and method-specific items of quality were assessed. The paucity of good quality studies of nifedipine used for the treatment of spontaneous preterm labour should be highlighted in meta-analyses or systematic reviews, which measure efficacy and should limit and influence the degree to which recommendations and guidelines are made on the basis of such studies.

How nurses cope with patient death: A systematic review and qualitative meta‐synthesis

Aims and objectives

To review literature on nurses’ coping strategies with patient death.

Background

Dealing with the loss of a patient was viewed as one of the most demanding and challenging encounters in clinical practice. Those nurses who are not competent in coping with patient death may be inadequate in supporting dying patients and their family members, and minimise the quality of end‐of‐life care. To get a broader understanding of how nurses cope with patient death and to develop meaningful and effective interventions, a systematic review which would help underpin the multidimensional approaches is needed.

Design

A systematic review.

Methods

Exhaustive searching in ten databases: CINAHL Plus, EMBASE, MEDLINE, AMED, PsycINFO, ProQuest Health & Medical Complete, ProQuest Dissertations & Theses Global, Google Scholar, EThOS and CareSearch. Meta‐aggregation was used to synthesise the findings of the included studies.

Results

This systematic review aggregated ten categories from the sixteen qualitative studies included, and then two synthesised findings were derived: intrinsic resources and extrinsic resources. The intrinsic resources consisted of setting boundaries, reflection, crying, death beliefs, life and work experience, and daily routines and activity. The extrinsic resources were comprised of talking and being heard, spiritual practices, education and programmes, and debriefing.

Conclusion

This systematic review synthesised the findings about what resources nurses use when coping with patient death and made recommendations on future directions. Areas which could be developed to improve deficiencies that nurses had when faced with the losses of their patients were identified. Nurses need more support resources, which better assist them in coping with patient death.

Relevance to clinical practice

The results of this systematic review could provide evidence for nurses’ coping strategies when dealing with patient death, and the recommendations could be employed by nurses to cope with the losses of patients.
