Seasonal variations in soil microbial community co-occurrence network complexity respond differently to field-simulated warming experiments in a northern subtropical forest.

Global warming may reshape seasonal changes in microbial community diversity and co-occurrence network patterns, with significant implications for terrestrial ecosystem function. We conducted a 2-year in situ field simulation of the effects of warming on the seasonal dynamics of soil microbial communities in a northern subtropical Quercus acutissima forest. Our study revealed that warming had no significant effect on the richness or diversity of soil bacteria or fungi in the growing season, whereas different warming gradients had different effects on their diversity in the nongrowing season. Warming also changed the microbial community structure, increasing the abundance of some thermophilic microbial species and decreasing the abundance of some symbiotrophic microorganisms. The co-occurrence network analysis of the microbial community showed that warming decreased the complexity of the intradomain network in the soil bacterial community in the growing and nongrowing seasons but increased it in the fungal community. Moreover, increasing warming temperatures increased the complexity of the interdomain network between bacteria and fungi in the growing season but decreased it in the nongrowing season, and the keystone species in the interdomain network changed with warming. Warming also reduced the proportion of positive microbial community interactions, indicating that warming reduced the mutualism, commensalism, and neutralism of microorganisms as they adapted to soil environmental stress. The factors affecting the fungal community varied considerably across warming gradients, with the bacterial community being significantly affected by soil temperature, MBC, NO3--N and NH4+-N, moreover, SOC and TN significantly affected fungal communities in the 4 °C warming treatment. These results suggest that warming increases seasonal differences in the diversity and complexity of soil microbial communities in the northern subtropical region, significantly influencing soil dynamic processes regulating forest ecosystems under global warming.

Structural basis of water-mediated cis Watson-Crick/Hoogsteen base-pair formation in non-CpG methylation.

Non-CpG methylation is associated with several cellular processes, especially neuronal development and cancer, while its effect on DNA structure remains unclear. We have determined the crystal structures of DNA duplexes containing -CGCCG- regions as CCG repeat motifs that comprise a non-CpG site with or without cytosine methylation. Crystal structure analyses have revealed that the mC:G base-pair can simultaneously form two alternative conformations arising from non-CpG methylation, including a unique water-mediated cis Watson-Crick/Hoogsteen, (w)cWH, and Watson-Crick (WC) geometries, with partial occupancies of 0.1 and 0.9, respectively. NMR studies showed that an alternative conformation of methylated mC:G base-pair at non-CpG step exhibits characteristics of cWH with a syn-guanosine conformation in solution. DNA duplexes complexed with the DNA binding drug echinomycin result in increased occupancy of the (w)cWH geometry in the methylated base-pair (from 0.1 to 0.3). Our structural results demonstrated that cytosine methylation at a non-CpG step leads to an anti→syntransition of its complementary guanosine residue toward the (w)cWH geometry as a partial population of WC, in both drug-bound and naked mC:G base pairs. This particular geometry is specific to non-CpG methylated dinucleotide sites in B-form DNA. Overall, the current study provides new insights into DNA conformation during epigenetic regulation.

Prospective observational study of Trichomonas tenax infection in patients with pneumonia.

Trichomonas tenax, an oral commensal parasite commonly found in the human mouth, is associated with periodontitis and poor oral hygiene. However, it has also been identified in the bronchoalveolar lavage fluid (BALF) of individuals with lung diseases. Notably, significant quantities of T. tenax have been isolated following bronchoscopy in cases of empyema and acute respiratory distress syndrome (ARDS). Furthermore, research has demonstrated its ability to induce inflammation in pulmonary epithelial cells. To comprehend the potential role of T. tenax in pneumonia, it is crucial to elucidate the relationship between the parasite and the disease. We investigated the clinical factors associated with T. tenax infection in patients with pneumonia. Employing nested polymerase chain reactions, we amplified nucleic acids from BALF and analyzed the relationships between T. tenax and various clinical factors. Our data revealed a significant association between T. tenax and bacterial infections, high pneumonia severity index (PSI) scores, nasogastric tube feeding, and pulmonary complications. Logistic regression analyses also showed strong associations between T. tenax and these clinical factors in pneumonia patients. These findings suggest that T. tenax infection in pneumonia is accompanied by bacterial infection and severe clinical manifestations.

Boundary sample-based class-weighted semi-supervised learning for malignant tumor classification of medical imaging.

Medical image classification plays a pivotal role within the field of medicine. Existing models predominantly rely on supervised learning methods, which necessitate large volumes of labeled data for effective training. However, acquiring and annotating medical image data is both an expensive and time-consuming endeavor. In contrast, semi-supervised learning methods offer a promising approach by harnessing limited labeled data alongside abundant unlabeled data to enhance the performance of medical image classification. Nonetheless, current methods often encounter confirmation bias due to noise inherent in self-generated pseudo-labels and the presence of boundary samples from different classes. To overcome these challenges, this study introduces a novel framework known as boundary sample-based class-weighted semi-supervised learning (BSCSSL) for medical image classification. Our method aims to alleviate the impact of intra- and inter-class boundary samples derived from unlabeled data. Specifically, we address reliable confidential data and inter-class boundary samples separately through the utilization of an inter-class boundary sample mining module. Additionally, we implement an intra-class boundary sample weighting mechanism to extract class-aware features specific to intra-class boundary samples. Rather than discarding such intra-class boundary samples outright, our approach acknowledges their intrinsic value despite the difficulty associated with accurate classification, as they contribute significantly to model prediction. Experimental results on widely recognized medical image datasets demonstrate the superiority of our proposed BSCSSL method over existing semi-supervised learning approaches. By enhancing the accuracy and robustness of medical image classification, our BSCSSL approach yields considerable implications for advancing medical diagnosis and future research endeavors.

Contribution of non-socioeconomic factors to healthy quality of life in socioeconomically deprived patients with advanced gastrointestinal cancer: Measuring attributable fraction.

BACKGROUND: The quality of life of patients with advanced gastrointestinal cancer is seriously impaired, and socioeconomic deprivation often has a serious impact on their quality of life. However, little is known about the relative contribution of non-socioeconomic factors to the quality of life of patients with advanced gastrointestinal cancer with socioeconomic deprivation. AIM: This study aims to investigate the situation and predictors of quality of life of patients with socioeconomic deprivation and evaluate the independent effects of some non-socioeconomic factors. DESIGN: A retrospective study based on cross-sectional design. METHODS: Data were obtained from 1075 patients with advanced gastrointestinal cancer who received family palliative treatment in the hospice ward of Zhongnan Hospital of Wuhan University from March 2010 to October 2020, including demographic and clinical questionnaires, Karnofsky Performance Status scale and Cancer Pain and Quality of Life Questionnaire of Chinese Cancer Patients. RESULTS: The quality of life of patients with advanced gastrointestinal cancer with socioeconomic deprivation is impaired and is affected by gait, self-care ability, abdominal distension, nutritional status, weight loss, constipation and posture. Improvement in six of these factors-gait, self-care ability, abdominal distension, nutritional status, weight loss and posture-has an independent positive impact on the development of a healthy quality of life for patients. CONCLUSIONS: Gait, self-care ability, abdominal distension, nutritional status, weight loss and posture are important determinants of healthy quality of life in patients with advanced gastrointestinal cancer with socioeconomic deprivation, and early identification and strength management of these non-socioeconomic factors may neutralize the negative impact of socioeconomic factors on the quality of life. IMPLICATIONS FOR PRACTICE: This study provides new ideas and intervention entry points for global nurses in practice innovations to improve the quality of life of socioeconomically deprived patients with advanced gastrointestinal cancer. It enables them to focus on the effectiveness of non-socioeconomic factors in the development and implementation of targeted care plans for patients with advanced gastrointestinal cancer experiencing socioeconomic deprivation globally. REPORTING METHOD: This study was reported in strict compliance with the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guideline. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

Analgesic effect of cocktail therapy combined with femoral nerve block in unicompartmental knee arthroplasty / 中国组织工程研究

BACKGROUND:With the further development of minimally invasive concepts,unicompartmental knee arthroplasty has become an important treatment for osteoarthritis of the knee;however,early postoperative pain adversely affects the recovery process,so effective analgesic measures are necessary.Femoral nerve block and cocktail therapy are common analgesic methods for unicompartmental knee arthroplasty,but there is a lack of studies confirming the analgesic effect and safety of their combined application. OBJECTIVE:To investigate the analgesic effect of cocktail therapy combined with femoral nerve block in unicompartmental knee arthroplasty. METHODS:One hundred patients who received unicompartmental knee arthroplasty from October 2021 to January 2023 were selected as the study subjects.They were divided into a control group(n=50)and a study group(n=50)using a random number table method.The femoral nerve block was used in the control group,while cocktail therapy combined with femoral nerve block was used in the study group during unicompartmental knee arthroplasty.Postoperative analgesia effect,analgesic frequency of dezocine injection within 2 days after surgery,motion range of affected knee joint,KSS function scores,and the occurrence of postoperative adverse reactions were compared between the two groups. RESULTS AND CONCLUSION:(1)Visual analog scale scores in the study group were lower than those in the control group at 12,24,and 48 hours after surgery(P<0.05).(2)The analgesic frequency of dezocine in the study group was less than that in the control group within 2 days after surgery(P<0.05).(3)The motion range in the study group was higher than that in the control group 1 and 3 days after surgery(P<0.05).On day 14 after surgery,there was no significant difference in motion range between the two groups(P>0.05).(4)The knee KSS score in the study group was higher than that in the control group at 2 weeks after surgery(P<0.05).There was no statistically significant difference in knee KSS scores between the two groups from 6 weeks to 6 months after surgery(P>0.05).(5)The difference in the occurrence of adverse reactions within 14 days after surgery was not significant between the two groups(P>0.05).(6)These results show that the use of cocktail therapy combined with femoral nerve block in unicompartmental knee arthroplasty can effectively reduce postoperative pain,improve the analgesic effect,reduce the frequency of analgesic drugs,and improve motion range of the early affected knee joint of patients.

Effectiveness of combined anteversion angle technique in total hip arthroplasty for treatment of ankylosing spondylitis affecting hip joint / 中国修复重建外科杂志

OBJECTIVE@#To explore the effectiveness of the combined anteversion angle technique in total hip arthroplasty (THA) for treating ankylosing spondylitis (AS) affecting the hip joint.@*METHODS@#A retrospective analysis was conducted on the clinical data of 73 patients with AS affecting the hip joint who underwent THA between August 2018 and August 2021. According to whether the combined anteversion angle technique was used in THA, the patients were divided into study group (37 cases, combined anteversion angle technique was used in THA) and control group (36 cases, traditional THA). There was no significant difference in baseline data such as gender, age, body mass index, disease duration, preoperative Harris score, range of motion (ROM), acetabular anteversion angle, acetabular abduction angle, femoral anteversion angle, and combined anteversion angle between the two groups ( P>0.05). The operation time, hospital stay, and complications of the two groups were recorded and compared. The Harris score and hip ROM were compared between the two groups before operation, at 1, 3, 6, 12 months after operation, and at last follow-up. The acetabular component anteversion angle, femoral component anteversion angle, acetabular component abduction angle, and component combined anteversion angle were measured postoperatively.@*RESULTS@#The operation time in the study group was significantly shorter than that in the control group ( P<0.05), and there was no significant difference in hospital stay between the two groups ( P>0.05). There was no intraoperative complication such as acetabular and proximal femoral fractures, neurovascular injuries in both groups, and the incisions healed by first intention. All patients were followed up 2-3 years, with an average of 2.4 years; there was no significant difference in the follow-up time between the two groups ( P>0.05). During the follow-up period, there was no complication such as hip dislocation, wound infection, delayed wound healing, deep venous thrombosis, and hip dislocation in both groups. The hip Harris score and ROM of the two groups gradually increased with time after operation, and the differences were significant when compared with those before operation ( P<0.05); the above two indicators of the study group were significantly better than those of the control group at each time point after operation ( P<0.05). Extensive bone ingrowth on the surface of the components could be observed in the anteroposterior X-ray films of the hip joint of the two groups at 12 months after operation, and the acetabular components was stable without femoral stem subsidence, osteolysis around the components, and heterotopic ossification. At last follow-up, the acetabular component anteversion angle, femoral component anteversion angle, and component combined anteversion angle in the study group were significantly superior to those in the control group ( P<0.05), except that there was no significant difference in the acetabular component abduction angle between the two groups ( P>0.05).@*CONCLUSION@#For patients with AS affecting the hip joint, the use of the combined anteversion angle technique during THA effectively promotes the recovery of hip joint function and enhances the postoperative quality of life of patients when compared to traditional THA.

Platelet-to-lymphocyte, neutrophil-to-lymphocyte and lymphocyte-to-monocyte ratios are related to cancer-related fatigue and quality of life in patients with cancer: a cross-sectional study.

OBJECTIVES: To explore the association of the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and lymphocyte-to-monocyte ratio (LMR) with cancer-related fatigue (CRF) and quality of life (QOL) in cancer patients. DESIGN: A cross-sectional study. SETTINGS: A grade A tertiary hospital in Wuhan, China. PARTICIPANTS: A total of 236 participants were recruited. Participants who were diagnosed with cancer received chemotherapy and/or radiotherapy, and aged ≥18 years were included in this study. PRIMARY AND SECONDARY OUTCOME MEASURES: The PLR, NLR and LMR were calculated based on the absolute lymphocyte count, neutrophil count, platelet count and monocyte count. The CRF and QOL of patients after the first chemotherapy/radiotherapy were evaluated. RESULTS: The median values (IQR) of PLR, NLR and LMR were 174.51 (126.14-261.02), 2.84 (1.64-5.24) and 2.56 (1.30-3.72), respectively. Univariate analysis indicated that high PLR (≥ 174.51), high NLR (≥ 2.84) and low LMR (< 2.56) at baseline significantly correlated with CRF and poor QOL after the first chemotherapy/radiotherapy (p<0.005). Multiple linear regression analysis indicated that elevated PLR might be an independent risk factor for CRF (p<0.001) and QOL (p=0.010) in cancer patients. CONCLUSION: PLR, NLR and LMR are associated with CRF and QOL in cancer patients. High PLR may predict severe CRF and poor QOL. Further studies are needed to validate these findings based on the expanded sample size.

Core clock gene BMAL1 and RNA-binding protein MEX3A collaboratively regulate Lgr5 expression in intestinal crypt cells.

The intestinal epithelium is highly regenerative. Rapidly proliferating LGR5+ crypt base columnar (CBC) cells are responsible for epithelial turnover needed to maintain intestinal homeostasis. Upon tissue damage, loss of LGR5+ CBCs can be compensated by activation of quiescent +4 intestinal stem cells (ISCs) or early progenitor cells to restore intestinal regeneration. LGR5+ CBC self-renewal and ISC conversion to LGR5+ cells are regulated by external signals originating from the ISC niche. In contrast, little is known about intrinsic regulatory mechanisms critical for maintenance of LGR5+ CBC homeostasis. We found that LGR5 expression in intestinal crypt cells is controlled by the circadian core clock gene BMAL1 and the BMAL1-regulated RNA-binding protein MEX3A. BMAL1 directly activated transcription of Mex3a. MEX3A in turn bound to and stabilized Lgr5 mRNA. Bmal1 depletion reduced Mex3a and Lgr5 expression and led to increased ferroptosis, which consequently decreased LGR5+ CBC numbers and increased the number of crypt cells expressing +4 ISC marker BMI1. Together, these findings reveal a BMAL1-centered intrinsic regulatory pathway that maintains LGR5 expression in the crypt cells and suggest a potential mechanism contributing to ISC homeostasis.

Meta-Analysis of Effects of Early Palliative Care on Health-Related Outcomes Among Advanced Cancer Patients.

BACKGROUND: Early palliative care (PC) has received more attention for improving health-related outcomes for advanced cancer patients in recent years, but the results of previous studies are inconsistent. OBJECTIVES: This study aimed to use meta-analysis and trial sequence analysis to evaluate the effect of early PC on health-related outcomes of advanced cancer patients. METHODS: All English publications were searched in PubMed, Web of Science, Embase, and the Cochrane Library from inception to March 2023, with a restriction that the study type was a randomized controlled trial. RESULTS: The results showed that early PC positively affected quality of life, satisfaction with care, and symptom burden reduction. However, early PC had no significant effect on anxiety or survival. Trial sequence analysis results showed that the effect of early PC on the quality of life was stable. DISCUSSION: This systematic review suggested that early PC could positively affect health-related outcomes for advanced cancer patients. Early PC can be used widely in clinical settings to improve health-related outcomes of advanced cancer. However, because of the trial sequence analysis results, further well-designed, clinical, randomized controlled trials with larger sample sizes are necessary to draw definitive conclusions.

Learning more from the inter-rater reliability of interstitial fibrosis assessment beyond just a statistic.

Interstitial fibrosis assessment by renal pathologists lacks good agreement, and we aimed to investigate its hidden properties and infer possible clinical impact. Fifty kidney biopsies were assessed by 9 renal pathologists and evaluated by intraclass correlation coefficients (ICCs) and kappa statistics. Probabilities of pathologists' assessments that would deviate far from true values were derived from quadratic regression and multilayer perceptron nonlinear regression. Likely causes of variation in interstitial fibrosis assessment were investigated. Possible misclassification rates were inferred on reported large cohorts. We found inter-rater reliabilities ranged from poor to good (ICCs 0.48 to 0.90), and pathologists' assessments had the worst agreements when the extent of interstitial fibrosis was moderate. 33.5% of pathologists' assessments were expected to deviate far from the true values. Variation in interstitial fibrosis assessment was found to be correlated with variation in interstitial inflammation assessment (r2 = 32.1%). Taking IgA nephropathy as an example, the Oxford T scores for interstitial fibrosis were expected to be misclassified in 21.9% of patients. This study demonstrated the complexity of the inter-rater reliability of interstitial fibrosis assessment, and our proposed approaches discovered previously unknown properties in pathologists' practice and inferred a possible clinical impact on patients.

Molecular characterization and expression of twenty interleukin-17 transcripts in the common Chinese cuttlefish (Sepiella japonica) in response to Vibrio harveyi infection.

The common Chinese cuttlefish (Sepiella japonica) is an essential species for stock enhancement by releasing juveniles in the East China Sea now. S. japonica is susceptible to bacterial diseases during parental breeding. In vertebrates, Interleukin-17 (IL-17) cytokine family plays critical roles in both acute and chronic inflammatory responses. In Cephalopoda, few studies have been reported on IL-17 genes so far. In this study, twenty IL-17 transcripts obtained from S. japonica were divided into eight groups (designated as Sj_IL-17-1 to Sj_IL-17-8). Multiple alignment analysis showed that IL-17s in S. japonica and human both contained four ß-folds (ß1-ß4), except for Sj_IL-17-6 with two ß-folds (ß1 and ß2), and the third and fourth ß-folds of Sj_IL-17-5 and Sj_IL-17-8 were longer than those of other Sj_IL-17. Protein structure and conserved motifs analysis demonstrated that Sj_IL-17-5 and Sj_IL-17-6 displayed different protein structure with respect to other six Sj_IL-17 proteins. The homology and phylogenetic analysis of amino acids showed that Sj_IL-17-5, Sj_IL-17-6 and Sj_IL-17-8 had low homology with the other five Sj_IL-17s. Eight Sj_IL-17 mRNAs were ubiquitously expressed in ten examined tissues, with dominant expression in the hemolymph. qRT-PCR data showed that the mRNA expression levels of Sj_IL-17-2, Sj_IL-17-3, Sj_IL-17-6, and Sj_IL-17-8 were significantly up-regulated in infected cuttlefishes, and Sj_IL-17-2, Sj_IL-17-6, Sj_IL-17-7, and Sj_IL-17-8 mRNAs Awere significantly up-regulated after bath infection of Vibrio harveyi, suggesting that certain Sj_IL-17s were involved in the immune response of S. japonica against V. harveyi infection. These results implied that Sj_IL-17s were likely to have distinct functional diversification. This study aims to understand the involvement of Sj_IL-17 genes in immune responses of cuttlefish against bacterial infections.

Unsatisfactory reproducibility of interstitial inflammation scoring in allograft kidney biopsy.

Interstitial inflammation scoring is incorporated into the Banff Classification of Renal Allograft Pathology and is essential for the diagnosis of T-cell mediated rejection. However, its reproducibility, including inter-rater and intra-rater reliabilities, has not been carefully investigated. In this study, eight renal pathologists from different hospitals independently scored 45 kidney allograft biopsies with varying extents of interstitial inflammation. Inter-rater reliabilities and intra-rater reliabilities were investigated by kappa statistics and conditional agreement probabilities. Individual pathologists' scoring patterns were examined by chi-squared tests and proportions tests. The mean pairwise kappa values for inter-rater reliability were 0.27, 0.30, and 0.26 for the Banff i score, ti score, and i-IFTA, respectively. No rater pair performed consistently better or worse than others on all three scorings. After dichotomizing the scores into two groups (none/mild and moderate/severe inflammation), the averaged conditional agreements ranged from 47.1% to 50.0%. The distributions of the scores differed, but some pathologists persistently scored higher or lower than others. Given the important role of interstitial inflammation scoring in the diagnosis of T-cell mediated rejection, transplant practitioners should be aware of the possible clinical implications of the far-from-optimal reproducibility.

Prediction of Survival Time in Advanced Lung Cancer: A Retrospective Study in Home-Based Palliative Care Unit.

Background: There is a large group of patients suffering from lung cancer and receiving home hospice care in China. However, little is known about the prediction of their survival time. The purpose of this study was to determine whether quality of life independently predicts survival among advanced lung cancer survivors who are receiving home-based palliative care. Methods: In this retrospective study, we analyzed data from 937 advanced lung cancer patients who had received home-based palliative care between March 2010 and March 2020. We used Kaplan-Meier survival curves to determine the factors associated with survival time and applied the Cox proportional hazards model to examine the effect of quality of life on survival. Results: The study included 928 patients with a mean age of 63 years; and 72.1% of them were men. Factors associated with shortened survival included age, sex, place of residence, weight loss, anorexia, nausea, edema, quality of life, and Karnofsky performance status. After adjusting for other variables in a multivariate Cox proportional hazards model, we found that quality of life was an independent positive predictor of survival. Conclusions: As an independent factor predicting the survival of advanced lung cancer patients, quality of life should be taken seriously. Medical staff and healthcare workers need to pay special attention to this predictive factor since it may serve as early risk identification indicator for professionals who provide home-based palliative care, helping them to create effective personalized care plans.

MEX3A Mediates p53 Degradation to Suppress Ferroptosis and Facilitate Ovarian Cancer Tumorigenesis.

Epithelial ovarian cancer is a highly heterogeneous and malignant female cancer with an overall low survival rate. Mutations in p53 are prevalent in the major ovarian cancer histotype, high-grade serous ovarian carcinoma (HGSOC), while p53 mutations are much less frequent in other ovarian cancer subtypes, particularly in ovarian clear cell carcinoma (OCCC). Advanced stage OCCC with wild-type (WT) p53 has a worse prognosis and increased drug resistance, metastasis, and recurrence than HGSOC. The mechanisms responsible for driving the aggressiveness of WT p53-expressing ovarian cancer remain poorly understood. Here, we found that upregulation of MEX3A, a dual-function protein containing a RING finger domain and an RNA-binding domain, was critical for tumorigenesis in WT p53-expressing ovarian cancer. MEX3A overexpression enhanced the growth and clonogenicity of OCCC cell lines. In contrast, depletion of MEX3A in OCCC cells, as well as ovarian teratocarcinoma cells, reduced cell survival and proliferative ability. MEX3A depletion also inhibited tumor growth and prolonged survival in orthotopic xenograft models. MEX3A depletion did not alter p53 mRNA level but did increase p53 protein stability. MEX3A-mediated p53 protein degradation was crucial to suppress ferroptosis and enhance tumorigenesis. Consistently, p53 knockdown reversed the effects of MEX3A depletion. Together, our observations identified MEX3A as an important oncogenic factor promoting tumorigenesis in ovarian cancer cells expressing WT p53. SIGNIFICANCE: Degradation of p53 mediated by MEX3A drives ovarian cancer growth by circumventing p53 tumor suppressive functions, suggesting targeting MEX3A as a potential strategy for treating of ovarian cancer expressing WT p53.

Objective:To systematically evaluate the influence of empathic nursing on anxiety,depression and hope level in patients with myocardial infarction.Methods:Randomized controlled trials involving the influence of em-pathic nursing on anxiety,depression and hope level in patients with myocardial infarction were searched in CNKI,VIP,Wanfang,CBM,PubMed,Cochrane Library and EMbase databases.After independent screening,data ex-traction and quality evaluation of the literatures by two researchers with evidence-based nursing experience,Rev-Man 5.3 software was used for meta-analysis.Results:A total of 11 randomized controlled trials were enrolled.Meta analysis indicated that after intervention,scores of self-rating anxiety scale(WMD=-7.67,95%CI(-11.31,-4.02),P＜0.001)and self-rating depression scale(WMD=-9.31,95%CI(-11.09,-7.53),P＜0.001)in empathic nursing group were significantly lower than those of control group,while Herth hope scale score(WMD=6.66,95%CI(4.83,8.50),P＜0.001)was significantly higher than that of control group.Conclusion:Current evidence indicate that empathic nursing can reduce anxiety and depression state,and improve the hope level in patients with myocardial infarction,but more high-quality studies are still needed to verify the results.

Effectiveness of Acceptance and Commitment Therapy for people with advanced cancer: A systematic review and meta-analysis of randomized controlled trials.

AIMS: To systematically review existing evidence and assess the effectiveness of Acceptance and Commitment Therapy for people with advanced cancer. DESIGN: Systematic review and meta-analysis of randomized controlled trials. DATA SOURCES: Nine databases, including PubMed, Web of Science, Cochrane Library, Embase, CINAHL, PsycINFO, Chinese National Knowledge Infrastructure, VIP Database and Wanfang, were searched. The search covered the period between the inception of the selected databases and August 2022. REVIEW METHODS: Two authors independently examined eligible studies and appraised the methodological quality of the included studies by applying the criteria suggested by the Cochrane Effective Practice and Organization of Care followed by data abstraction. The Template for Intervention Description and Replication (TIDieR) checklist was used to identify intervention characteristics. Meta-analysis was performed using RevMan 5.4 software, and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to evaluate the certainty of evidence. RESULTS: Eight studies, involving 488 people with advanced cancer, were included. The results showed significant effects of Acceptance and Commitment Therapy on the improvement of quality of life and the alleviation of anxiety, depression, psychological distress and fatigue in people with advanced cancer. However, its effects in relieving psychological flexibility and pain were not statistically significant. The certainty of the evidence was low to moderate. CONCLUSION: People with advanced cancer can benefit from Acceptance and Commitment Therapy, which is conducive to improving their health outcomes. IMPACT: This review provides evidence about the effectiveness of Acceptance and Commitment Therapy in people with advanced cancer. Further well-designed studies with larger sample sizes are required. This review may help nurses and researchers to design and implement Acceptance and Commitment Therapy in clinical practice, thereby improving health outcomes in this population. PROSPERO REGISTRATION NUMBER: CRD42021244568.

Effects of various treatments for preventing oral mucositis in cancer patients: A network meta-analysis.

BACKGROUND: Oral mucositis (OM) is a common side effect of chemotherapy and radiotherapy in patients with cancers. The prevention or treatment of OM in cancer patients is crucial in the treatment of cancer. METHODS: We searched PubMed, Embase, and Cochrane Library for the randomized control trials (RCTs) of interventions for preventing and treating OM. Network meta-analysis (NMA) was performed to estimate odds ratios (ORs) and 95% confidence intervals (CI) from both direct and indirect evidence. The prespecified primary efficacy outcome was the treatment effect of moderate to severe oral mucositis with 12 interventions. The outcome was moderate to a severe grade of OM. RESULTS: This study included 55 RCTs with 3,552 participants. The results showed that honey significantly lowered the risk of chemo/radiotherapy-induced moderate to severe oral mucositis than placebo (OR: 0.01, 95%CI 0.00 to 0.45), followed by lignocaine (OR: 0.07, 95%CI 0.00 to 0.95). The surface under cumulative ranking curve (SUCRA) values for honey were 0.95, followed by lignocaine (SUCRA, 0.81) and benzydamine (SUCRA, 0.78). CONCLUSIONS: The honey is effective for patients with cancer undergoing chemotherapy or radiotherapy-induced oral mucositis.

Factors associated with sleep quality among nurse managers during regular prevention and control of the COVID-19 in China: a cross-sectional study.

BACKGROUND: Nurse managers play a pivotal role in quality patient care and staff satisfaction and retention. An overwhelming amount of work tasks and responsibilities might result in their sleep problems which are expected to aggravate in the context of the COVID-19, thereby affecting their overall health and work quality. However, little attention has been paid to sleep quality among nurse managers. This study aimed to investigate the prevalence of sleep disorders among nurse managers and identify related factors of sleep quality during regular prevention and control of the COVID-19 pandemic in China. METHODS: This cross-sectional online survey was conducted in 14 hospitals on a sample of 327 nurse managers in China. Participants were invited to complete the general demographic questionnaire, Pittsburgh Sleep Quality Index (PSQI) and Simplified Coping Style Questionnaire (SCSQ). Multiple linear regression analysis was used to explore the influencing factors of sleep quality among nurse managers. RESULTS: In this study, 43.7% of nurse managers suffered from sleep disorders. Active coping style and frequent exercise were positive factors that could influence nurse managers' sleep quality, while passive coping style and age over 41 years old were negative predictors, collectively accounting for 52.0% of the variance of sleep quality. CONCLUSIONS: The issue of sleep disorders among nurse managers during regular epidemic prevention and control period is underscored. Coping style and demographic factors including age and frequency of exercise can significantly affect nurse managers' sleep quality. Healthcare administrators should pay more attention to nurse managers' sleep disorders and implement targeted strategies based on influencing factors to ensure their sleep quality.
