Knowledge mapping of barriers and strategies for clinical practice guideline implementation: a bibliometric analysis.

OBJECTIVE: This study provides a comprehensive overview of the knowledge structure and research hotspots regarding barriers and strategies for the implementation of clinical practice guidelines. METHODS: Publications on barriers and strategies for guideline implementation were searched for on Web of Science Core Collection from database inception to October 24, 2022. R package bibliometrix, VOSviewer, and CiteSpace were used to conduct the analysis. RESULTS: The search yielded 21,768 records from 3,975 journals by 99,998 authors from 3,964 institutions in 186 countries between 1983 and 2022. The number of published papers had a roughly increasing trend annually. The United States, the United Kingdom, and Canada contributed the majority of records. The University of Toronto, the University of Washington, and the University of Sydney were the biggest node in their cluster on the collaboration network map. The three journals that published the greatest number of relevant studies were Implementation Science , BMJ Open , and BMC Health Services Research . Grimshaw JM was the author with the most published articles, and was the second most co-cited author. Research hotspots in this field focused on public health and education, evidence-based medicine and quality promotion, diagnosis and treatment, and knowledge translation and barriers. Challenges and barriers, as well as societal impacts and inequalities, are likely to be key directions for future research. CONCLUSIONS: This is the first bibliometric study to comprehensively summarize the research trends of research on barriers and strategies for clinical practice guideline implementation. A better understanding of collaboration patterns and research hotspots may be useful for researchers. SPANISH ABSTRACT: http://links.lww.com/IJEBH/A247.

Risk of kidney and liver diseases after COVID-19 infection: A systematic review and meta-analysis.

COVID-19 is not only associated with substantial acute liver and kidney injuries, but also with an elevated risk of post-acute sequelae involving the kidney and liver system. We aimed to investigate whether COVID-19 exposure increases the long-term risk of kidney and liver disease, and what are the magnitudes of these associations. We searched PubMed, Embase, Web of Science, ClinicalTrials.gov, and the Living Overview of the Evidence COVID-19 Repository for cohort studies estimating the association between COVID-19 and kidney and liver outcomes. Random-effects meta-analyses were performed to combine the results of the included studies. We assessed the certainty of the evidence using the Grading of Recommendations Assessment, Development and Evaluation approach. Fifteen cohort studies with more than 32 million participants were included in the systematic review COVID-19 was associated with a 35% greater risk of kidney diseases (10 more per 1000 persons; low certainty evidence) and 54% greater risk of liver disease (3 more per 1000 persons; low certainty evidence). The absolute increases due to COVID-19 for acute kidney injury, chronic kidney disease, and liver test abnormality were 3, 8, and 3 per 1000 persons, respectively. Subgroup analyses found no differences between different type of kidney and liver diseases. The findings provide further evidence for the association between COVID-19 and incident kidney and liver conditions. The absolute magnitude of the effect of COVID-19 on kidney and liver outcomes was, however, relatively small.

The effects of exercise on insomnia disorders: An umbrella review and network meta-analysis.

OBJECTIVE: To summarize the evidence of various exercise modalities on population with insomnia disorders. METHOD: PubMed, Embase, Cochrane Library, and Web of Science were searched for eligible studies published from inception to October 2022 and updated on September 2023. Systematic reviews with meta-analyses and randomized controlled trials designed to investigate the effect of various exercise modalities on population with insomnia were eligible. RESULTS: A total of 4 SRs with (very) low methodological quality and 1034 participants in 10 network meta-analyses explored the association between different types and intensity exercise modalities with insomnia disorders. Various exercise modalities could significantly improve total sleep time and sleep quality and alleviate insomnia severity. Compared to passive control, moderate aerobic exercise, moderate aerobic exercise combined with light intensity strength and mind-body exercise can improve sleep efficiency and reduce wake after sleep onset by objectively measured. Moderate intensity strength, light intensity strength and mind-body exercise can improve sleep efficiency subjectively measured; mind-body exercise can reduce sleep onset latency and wake time after sleep onset, and increase total sleep time; moderate aerobic exercise can reduce sleep onset latency. Moderate intensity strength, light intensity strength, mind body exercise and moderate aerobic exercise combined with light intensity strength can the severity of insomnia and improv sleep quality. CONCLUSION: Exercise had a positive effect on relief insomnia and improve sleep quality. Moderate aerobic exercise, mind-body exercise and moderate aerobic exercise combined with light intensity strength play an important role in improving the sleep quality in people with insomnia disorders.

Traditional Chinese medicine for insomnia: Recommendation mapping of the global clinical guidelines.

ETHNOPHARMACOLOGICAL RELEVANCE: Traditional Chinese Medicine (TCM) represents a rich repository of empirically-developed traditional medicines. The findings call for more rigorous study into the efficacy, safety, and mechanisms of action of TCM remedies to strengthen the evidence base. AIM OF THE STUDY: To systematically review the quality of insomnia clinical practice guidelines that involve TCM recommendations and to summarize the certainty of evidence supporting the recommendations, strength, and consistency of recommendations, providing valuable research references for the development of future insomnia guidelines. MATERIALS AND METHODS: We systematically searched PubMed, Web of Science, Embase, CNKI, Wanfang, Chinese Biomedical Literature Database, Chinese Medical Association, Chinese Sleep Research Society, Medsci, Medlive, British National Institute of Health and Clinical Excellence (NICE), and the International Guidelines Collaboration Network (GIN) for clinical practice guidelines on insomnia from inception to March 5, 2023. Four evaluators conducted independent assessments of the quality of the guidelines by employing the AGREE II tool. Subsequently, the guideline recommendations were consolidated and presented as evidence maps. RESULTS: Thirteen clinical practice guidelines addressing insomnia, encompassing 211 recommendations (consisting of 127 evidence-based and 84 expert consensus recommendations), were deemed eligible for inclusion in our analysis. The evaluation results revealed an overall suboptimal quality, with the "scope and purpose" domain achieving the highest score (58.1%), while the "applicability" domain garnered the lowest score (13.0%). Specifically, it was observed that 74.8% (n = 95) of the evidence-based recommendations were supported by evidence of either very low or low certainty, in contrast to the expert consensus recommendations, which accounted for 61.9% (n = 52). We subsequently synthesized 44 recommendations into four evidence maps, focusing on proprietary Chinese medicines, Chinese medicine prescriptions, acupuncture, and massage, respectively. Notably, Chinese herbal remedies and acupuncture exhibited robust support, substantiated by high-certainty evidence, exemplified by interventions such as Xuefu Zhuyu decoction, spleen decoction, body acupuncture, and ear acupuncture, resulting in solid recommendations. Conversely, proprietary Chinese medicines needed more high-certainty evidence, predominantly yielding weak recommendations. As for other therapies, the level of certainty was predominantly categorized as low or very low. Recommendations about magnetic therapy, bathing, and fumigation relied primarily on expert consensus, needing more substantive clinical research evidence, consequently forming weak recommendations. Hot ironing and acupoint injection recommendations were weakly endorsed, primarily based on observational studies. Furthermore, interventions like qigong, gua sha, and moxibustion displayed a relatively limited number of clinical studies, necessitating further exploration to ascertain their efficacy. CONCLUSIONS: Our analysis revealed a need for substantial improvement in the quality of all the included guidelines related to insomnia. Notably, recommendations for Traditional Chinese Medicine (TCM) treatments predominantly rely on low-certainty evidence. This study represents a pioneering effort in the utilization of recommendation mapping to both present and identify existing gaps in the evidence landscape within TCM therapies, thus setting the stage for future research initiatives. The evidence supporting TCM therapy recommendations must be fortified to achieve a more substantial level of recommendation and higher certainty. Consequently, there exists a critical and pressing demand for high-quality clinical investigations dedicated to TCM, with a specific focus on ascertaining its long-term efficacy, safety, and potential side effects in the context of insomnia treatment. These endeavors are poised to establish a robust scientific foundation to inform the development of TCM therapy recommendations within the insomnia guidelines.

Matrix remodeling associated 7 proteins promote cutaneous wound healing through vimentin in coordinating fibroblast functions.

Wound healing depends largely on the remodeling of the extracellular matrix around and reorganization of tissue-resident cells. Matrix remodeling associated 7 (MXRA7) is a member of the matrix remodeling-associated gene family and is involved in matrix remodeling-associated processes, such as inflammatory neovascularization, liver injury, and autoimmune skin disease. To investigate whether and how MXRA7 participate in cutaneous wound healing, an ear-punching model was utilized in wild-type (WT) and MXRA7-deficient mice, and the dermal fibroblasts from these mice were further studied in vitro. Results showed that the MXRA7 deficiency impaired the wound healing process in mice. Quantitative PCR indicated that lack of MXRA7 impaired the expression of several extracellular matrix genes (e.g., MMP-2) and inhibited signaling pathways (e.g., STAT3) in healing ear tissues. In in vitro culture system, migration, contraction, or proliferation of fibroblasts was impaired upon MXRA7 deficiency. Pull-down and mass spectrum assay revealed that vimentin was among the proteins that bound MXRA7 proteins in cells, and further investigations indicate MXRA7 was an autocrine factor in fibroblasts that involved vimentin in certain ways, such as JNK and STAT3/STAT5 signaling pathways in our study. In conclusion, MXRA7 proteins promote wound healing through vimentin in coordinating fibroblast functions.

Altered expression of matrix remodelling associated 7 (MXRA7) in psoriatic epidermis: Evidence for a protective role in the psoriasis imiquimod mouse model.

Preliminary data mining performed with Gene Expression Omnibus data sets implied that psoriasis may involve the matrix remodelling associated 7 (MXRA7), a gene with little function information yet. To test that hypothesis, studies were performed in human samples and murine models. Immunohistochemistry in normal human skin showed that MXRA7 proteins were present across the full epidermal layer, with highest expression level detected in the basal layer. In psoriatic samples, MXRA7 proteins were absent in the basal stem cells layer, while suprabasal keratinocytes were stained at a higher level than in normal tissues. In an imiquimod-induced psoriasis-like disease model in mice, diseased skins manifested similar MXRA7 expression pattern and change as in human samples, and MXRA7-deficient mice developed severer psoriasis-like diseases than wild-type mice did. While levels of propsoriatic genes (eg IL17, IL22, IL23) in imiquimod-stimulated MXRA7-deficient mice were higher than in wild-type mice, keratinocytes isolated from MXRA7-deficient mice showed increased proliferation upon differentiation induction in culture. These data demonstrated that MXRA7 gene might function as a negative modulator in psoriasis development when propsoriatic factors attack, presumably via expression alteration or redistribution of MXRA7 proteins in keratinocytes.

[Expression Changes of Matrix Reconstitution-related Genes in Bone Marrow during 5-Fluorouracil-Induced Hemopoietic Injury and Their Significance].

OBJECTIVE: To explore the expression change of the genes related with matrix reconstitution during the injury and reconstitution of murine bone marrow following treatment with 5-fluorouracil (5-FU). METHODS: C57BL/6 mice received intraperitoneal injection of 5-FU (200 mg/kg), and peripheral blood cell counts were monitored at 3, 6, 9, 15, 21, 27 days after treatment. Bone marrow cells were harvested at these times for total RNA extraction using TRIzol. Reverse transcriptions in combination with real-time PCR were performed for detecting expression of genes related with matrix reconstitution, including ECM-1, MMP-2, MMP-3, MMP-13 and TIMP-1. RESULTS: After injection of 5-FU, the numbers of three line cells in peripheral blood (i.e. RBC, WBC and platelets) decreased and then recovered with differential dynamics. Similarly, RT-qPCR revealed that all the 5 detected gene expressions were significantly up-regulated during the injury. The mRNA expression of MMP-2 reached to peak at day 3 while the other genes reached to peak at day 6. MMP-3 has a low expression when compared with others, but its expression increased significantly after injury. CONCLUSION: In 5-FU induced hematopoietic injury and reconstitution model, matrix reconstitution-related genes may play an important role in hematopoietic reconstitution, but different genes play different roles at various time, and cooperate with each other for hematopoietic reconstitution.
