RESUMEN
MYB (myoblast) protein comes in large quantities and a wide variety of types and plays a role in most eukaryotes in the form of transcription factors (TFs). One of its important functions is to regulate plant responses to various stresses. However, the role of MYB TFs in regulating stress tolerance in strawberries is not yet well understood. Therefore, in order to investigate the response of MYB family members to abiotic stress in strawberries, a new MYB TF gene was cloned from Fragaria vesca (a diploid strawberry) and named FvMYB108 based on its structural characteristics and evolutionary relationships. After a bioinformatics analysis, it was determined that the gene belongs to the R2R3-MYB subfamily, and its conserved domain, phylogenetic relationships, predicted protein structure and physicochemical properties, subcellular localization, etc. were analyzed. After qPCR analysis of the expression level of FvMYB108 in organs, such as the roots, stems, and leaves of strawberries, it was found that this gene is more easily expressed in young leaves and roots. After multiple stress treatments, it was found that the target gene in young leaves and roots is more sensitive to low temperatures and salt stimulation. After these two stress treatments, various physiological and biochemical indicators related to stress in transgenic Arabidopsis showed corresponding changes, indicating that FvMYB108 may be involved in regulating the plant's ability to cope with cold and high-salt stress. Further research has found that the overexpression of this gene can upregulate the expression of AtCBF1, AtCOR47, AtERD10, and AtDREB1A related to low-temperature stress, as well as AtCCA1, AtRD29a, AtP5CS1, and AtSnRK2.4 related to salt stress, enhancing the ability of overexpressed plants to cope with stress.

AIMS: To understand the clinical status of implementing individualized repositioning frequency-and its barriers and facilitators-among critical care nurses in China, in view of developing targeted intervention strategies and improving guideline implementation. DESIGN: A cross-sectional survey. METHODS: A self-report questionnaire was developed with reference to the Theoretical Domains Framework and administered to critical care nurses in 15 hospitals across eastern, southern, western, northern, and central geographical areas of China from 20 February 2023 to 16 March 2023. Data were collected for personal demographics, clinical practice status, and from Likert-type responses about barriers to and facilitators of implementing individualized repositioning frequency. RESULTS: In total, 574 effective questionnaires were collected. Only 3.8 % of respondents reported that their hospital/ward uses an individualized repositioning frequency rule. Six facilitator domains identified were: social/professional role and identity; beliefs about capabilities; optimism; beliefs about consequences; reinforcement; and intentions. Seven barrier domains were: knowledge; skills; goals; memory, attention and decision processes; environmental context and resources; social influences; and behavioral regulation. Inferential analysis showed that critical care nurses who had higher degrees, more years of work, more environmental support, and more nursing experience were prone to being more positive in response to the implementation of individualized repositioning frequency. CONCLUSION: The clinical practice status of implementing individualized repositioning frequency among critical care nurses in China is unsatisfactory. Implementation is essential but complex and is influenced by several factors. Theory-based suggestions for improving this situation are provided on the basis of identified barriers.

AIMS AND OBJECTIVES: (i) To estimate the national incidence of unplanned removal of peripherally inserted central catheters (PICCs) in China. (ii) To explore the associated risk factors to provide evidence for the prevention. DESIGN: A multi-centre prospective cohort study. METHODS: A representative sample of 3222 Chinese adult patients with successful PICC insertion was recruited for the PICC Safety Management Research (PATH) using a two-stage cluster sampling method from December 2020 to June 2022. Sixty hospitals from seven Chinese provinces representing all geographical regions were selected. Demographic information and PICC characteristics were collected using a standard online case report form. Risk factors for the unplanned removal of PICCs were assessed using a cause-specific hazard model and verified using a sub-distribution hazard model. STROBE guidelines were followed in reporting this study. RESULTS: Three thousand one hundred and sixty-six patients were included in the final analysis with a mean age of 59 years and a total of 344,247 catheter days. The incidence of unplanned removal was 10.04%. Female, with thrombosis history, PICC insertion due to infusion failure, valved catheter and double-lumen catheter were risk factors, whereas longer insertion and exposure length were protective factors in the cause-specific hazard model. Higher BMI became an independent risk factor in the sub-distribution hazard model. CONCLUSIONS: Unplanned removal of PICCs is a serious clinical challenge in China. Our findings call for prevention strategies targeting the identified risk factors. RELEVANCE TO CLINICAL PRACTICE: Our study characterised the epidemiology of unplanned removal of PICCs among Chinese adult inpatients, highlighting the need for prevention among this population and providing a basis for the formulation of relevant prevention strategies. PATIENT OR PUBLIC CONTRIBUTION: Patients contributed through sharing their information required for the case report form. Healthcare professionals who provide direct care to the patient at each medical centre contributed by completing the online case report form.

Hepatocellular carcinoma (HCC) initiated by hepatitis B virus (HBV) infection is a complicated process. MiR-155 can alter the immune microenvironment to affect the host's anti-infective ability. This study investigated the mechanism by which miR-155 affects tumour-associated macrophage (TAM) polarization at a molecular level, thus affecting the malignant progression of HBV+ HCC. MiR-155 and TAM-related cytokine expression were analysed by qRT-PCR. The distribution of TAMs was detected by immunohistochemistry. The effect of the aberrant miR-155 expression on macrophage polarization was examined by flow cytometry. The targeted relationship was verified by dual-luciferase assay, and the protein level of src homology 2 domain-containing inositol polyphosphate 5-phosphatase 1 (SHIP1) was detected by western blot. The proliferation of HCC cells was examined by CCK-8 and colony formation assays. Invasion and migration of HCC cells were detected by transwell assay. In HBV+ HCC tissues, miR-155 was significantly highly expressed and the number of CD206-positive TAM (CD206+ TAM) and CD68-positive TAM (CD68+ TAM) were higher than those in HBV- HCC tissues. In addition, miR-155 overexpression significantly promoted M2-type macrophage polarization, whilst miR-155 silencing expression significantly promoted M1-type macrophage polarization. Besides, the miR-155/SHIP1 axis accelerated HCC cell invasion, proliferation and migration by inducing M2-type macrophage polarization. MiR-155 accelerates HCC cell proliferation, migration and invasion by targeting SHIP1 expression and inducing macrophage M2 polarization. This finding provides new insights into the development of novel therapeutic strategies for combatting HBV+ HCC and a new reference for exploring anti-tumour immunotherapy.

OBJECTIVE: To report the overall prevalence of social frailty among older people and provide information for policymakers and authorities to use in developing policies and social care. DESIGN: A systematic review and meta-analysis. SETTING AND PARTICIPANTS: We searched 4 databases (PubMed, Embase, Web of Science, and Google Scholar) to find articles from inception to July 30, 2022. We included cross-sectional and cohort studies that provided the prevalence of social frailty among adults aged 60 years or older, in any setting. METHODS: Three researchers independently reviewed the literature and retrieved the data. A risk of bias tool was used to assess each study's quality. A random-effect meta-analysis was performed to pool the data, followed by subgroup analysis, sensitivity analysis, and meta-regression. RESULTS: From 761 records, we extracted 43 studies with 83,907 participants for meta-analysis. The pooled prevalence of social frailty in hospital settings was 47.3% (95% CI: 32.2%-62.4%); among studies in community settings, the pooled prevalence was 18.8% (95% CI: 14.9%-22.7%; P < .001). The prevalence of social frailty was higher when assessed using the Tilburg Frailty Indicator (32.3%; 95% CI: 23.1%-41.5%) than the Makizako Social Frailty Index (27.7%; 95% CI: 21.6%-33.8%) or Social Frailty Screening Index (13.4%; 95% CI: 8.4%-18.4%). Based on limited community studies in individual countries using various instruments, social frailty was lowest in China (4.9%; 95% CI: 4.2%-5.7%), followed by Spain (11.6%; 95% CI: 9.9%-13.3%), Japan (16.2%; 95% CI: 12.2%-20.3%), Korea (26.6%; 95% CI: 7.1%-46.1%), European urban centers (29.2%; 95% CI: 27.9%-30.5%), and the Netherlands (27.2%; 95% CI: 16.9%-37.5%). No other subgroup analyses showed any statistically significant prevalence difference between groups. CONCLUSION AND IMPLICATIONS: The prevalence of social frailty among older adults is high. Settings, country, and method for assessing social frailty affected the prevalence. More valid comparisons will await consensus on measurement tools and more research on geographically representative populations. Nevertheless, these results suggest that public health professionals and policymakers should seriously consider social frailty in research and program planning involving older adults.

Pressure injury is a serious and preventable problem in intensive care units. Translating guidelines into clinical practice can reduce the incidence of pressure injury. Identifying clinical status, barriers and facilitators contribute to guideline implementation. To identify the knowledge, attitudes, and practices of pressure injury prevention in Chinese critical care nurses. Secondary data were extracted from a multicentric clinical trial. Knowledge and attitudes toward pressure injury prevention were assessed by a fourteen-item questionnaire. The observed practices were recorded using a case report form. The report complies with the STROBE statement. A total of 950 critical care nurses in 15 hospitals from six provinces of China were investigated. A total of 53.1% of nurses received a median score of 6 points or less. Knowledge regarding the repositioning procedure, risk assessment, and heel pressure injury prevention was insufficient. Over 99% of nurses strongly or somewhat agreed that pressure injury prevention was very important and that they were willing to take measures to prevent pressure injury. A total of 27 781 patient days of pressure injury prevention practice were recorded. Repositioning was the most commonly used prevention measure, followed by support surfaces and prophylactic dressings. A combination of repositioning, support surface, and prophylactic dressing was lacking. Chinese critical nurses showed a low level of knowledge and a positive attitude toward pressure injury prevention. Practices of pressure injury prevention were unsatisfactory. There is a clear gap between the guidelines and clinical practices. The barrier (low-level knowledge) and facilitator (positive attitude) were identified in this study. According to these findings, strategies need to be developed to promote guideline implementation.

BACKGROUND: Intracavity electrocardiogram (IC-ECG) guidance is an effective technology for monitoring the tip locations of centrally inserted central catheters (CICCs) and peripherally inserted central catheters (PICCs). However, for patients with an indwelling CICC, there has been no study on whether the CICC affects PICC tip positioning with IC-ECG guidance. METHODS: Thirty people with a CICC requiring PICC insertion, matched with age to controls without a CICC. The stability of IC-ECG waveforms, the amplitude of P-waves, and the accuracy of PICC tip location were compared. RESULTS: There was no significant difference in the stability of the IC-ECG waveforms (χ2 = 0.22, p = 0.64). The amplitudes of baseline P-waves and ideal P-waves also showed no significant difference (t1 = 0.06, p1 = 0.96, t2 = 0.80, p2 = 0.43). Neither the accuracy of tip location (χ2 = 1.40, p = 0.50) nor the distance of PICC tip (t = -0.03, p = 0.98) were significantly different. CONCLUSION: For patients with an indwelling CICC, the position of PICC tip can be accurately determined by the dynamic changes in the P-wave amplitude.

Background: X-ray and pH testing, which clinical practice guidelines have proven to be effective in determining nasogastric tube (NGT) placement, were named the high-value methods. Implementation strategies can help to integrate high-value methods into particular contexts. The aim of this systematic review was to summarize the evidence of implementation strategies aimed at improving high-value verification methods of NGT placement. Methods: PubMed, ProQuest, and CINAHL were searched until June 2022. The Cochrane Effective Practice and Organization of Care (EPOC) taxonomy was used to categorize implementation strategies. Results: The initial search identified 1,623 records. Of these, 64 full-text studies were reviewed. Finally, 12 studies were included and used for qualitative synthesis. Eleven studies used an education component as an implementation strategy. Only one study based their implementation strategy on a barriers and facilitators assessment. None of the studies reported enough detail of the implementation strategy used in their studies. Seven studies were eligible for inclusion in the meta-analysis. Three of these seven studies revealed a significant improvement of the high-value method after strategy implementation. As heterogeneity was present in the high level, the pooled effect estimated was not calculated. Conclusion: Most studies used an implementation strategy with an educational component. Unfortunately, no conclusion can be drawn about which strategy is most effective for improving high-value verification methods of NGT placement due to a high level of heterogeneity and a lack of studies. We recommend that future studies fully connect their implementation strategies to influencing factors and better report the details of implementation strategies.

RESUMEN
BACKGROUND: Given that few studies have explored the association between oral health and frailty among older nursing home residents, the purpose of this study was to assess the association between oral health (i.e., the number of teeth and oral behaviors) and frailty in this population using the Chinese Longitudinal Healthy Longevity Survey (CLHLS). METHODS: This was a national cross-sectional study derived from the seventh wave of CLHLS in 2018, consisting of 365 older nursing home residents aged 65 years or older. The frailty index was constructed based on 32 variables consisting of self-rated health status, anxiety, depression, ADL and IADL. Oral health was measured through the number of natural teeth and tooth brushing behavior. Multiple logistic regression was used to identify this association between the number of teeth, oral health behaviors, and frailty. RESULTS: The mean age of this sample was 87.6 (SD = 9.5), with 154 (42.2%) males. The prevalence of frailty and edentulism was 71.2% and 33.4%, respectively. Multiple logistic regression analysis found that the likelihood of frailty decreased with an increased number of teeth, with an OR of 0.94 (95% CI: 0.91-0.98). Compared with participants with edentulism, older adults with 1 to 20 teeth had a lower likelihood of frailty (OR = 0.39, 95% CI: 0.17-0.88); these results were also found in older adults with more than 20 teeth (OR = 0.20, 0.07-0.57). Additionally, older adults who brush their teeth regularly have a lower likelihood of frailty than those who never brush their teeth (OR = 0.37, 95% CI: 0.13-0.99). CONCLUSION: Older nursing home residents who maintain their natural teeth can help lower the risk of frailty, and regular toothbrushing also contributes to decreasing the risk of frailty. Our study emphasizes the importance of oral health, and cohort studies with large-scale samples to address this important issue are warranted in the future.

Background: Pressure injury is a common problem in intensive care units. Critical care nurses play an important role in multidisciplinary teams performing pressure injury treatment. Identifying the clinical status of pressure injury treatment may contribute to improving care quality. Aim: To identify the knowledge, attitudes, and practices regarding pressure injury treatment in critical care nurses. Design: A cross-sectional survey. Methods: Secondary data were extracted from a multicenter clinical trial. Knowledge and attitudes toward pressure injury treatment were assessed through a self-administered eight-item questionnaire. The observed practices were recorded using a case report form. The report was in accordance with the STrengthening the Reporting of OBservational studies in Epidemiology (STROBE) statement. Results: A total of 950 critical care nurses in 15 hospitals from six provinces/municipalities of China were investigated. The mean knowledge score was 2.89 ± 1.16 (95% confidence interval: 2.82-2.97) out of a possible total of 5 points. The correct rates of selecting wound dressings and pain management were 34.4% and 45.6%, respectively. The mean attitude score was 9.07 ± 1.09 (95% confidence interval: 9.00-9.13) out of a possible total of 12 points. A total of 2092 patient days of pressure injury treatment practices were observed and recorded. Repositioning was the most commonly employed treatment measure (98.8%). Foam dressing was the common dressing for stage I (53.6%), stage II (47.5%), and more severe pressure injury (67.9%), including stage III, IV, unstageable, and suspected deep tissue injury. Conclusion: Critical care nurses exhibited a generally low level of knowledge and moderate attitudes regarding pressure injury treatment. Practices of pressure injury treatment were generally acceptable.
RESUMEN
Purpose: Although the association between cognitive impairment and mortality has been widely described among community-dwelling older adults, this association in hospitalized patients was limited. Objectives: This study's purpose was to explore the association between cognitive impairment and 30-day mortality after adjustment of factors among Chinese in-patients. Methods: This was a large-scale prospective study based on a cohort of patients aged 65 years and older, whose cognitive function was assessed using the Mini-Cog instrument, followed up at 30-days for mortality. Multivariate logistic regression models were used to assess the association between cognitive impairment and 30-day mortality. Results: There were 9,194 inpatients in our study, with an average age of 72.41 ± 5.72. The prevalence of cognitive impairment using the Mini-Cog instrument was 20.5%. Multivariable analyses showed that patients with cognitive impairment have an increased risk of 30-day mortality, compared to those with normal cognitive function (OR = 2.83,95%CI:1.89-4.24) in an unadjusted model. In the fully adjusted model, Patients with cognitive impairment had an increased risk of 30-day mortality compared to those with normal cognitive function in the completely adjusted model (OR = 1.76,95% CI: 1.14-2.73). Additionally, this association still existed and was robust after performing a stratified analysis of age, gender, frailty and depression, with no significant interaction (P > 0.05). Conclusions: Our study found that older Chinese in-patients with cognitive impairment have a 1.76-fold risk of 30-day mortality compared to patients with normal cognitive function, suggesting that clinicians and nurses need to early implement cognitive function screening and corresponding interventions to improve clinical outcomes for older in-patients.
RESUMEN
BACKGROUND: Some studies associate frailty and postoperative mortality in hip or knee replacement patients, and others have explored the relationship between the frailty index and changes in postoperative mortality in hip or knee replacement patients, but their findings are not consistent. This meta-analysis and systematic review aimed to pool the results of existing studies to explore whether frailty is an independent risk factor for postoperative mortality in patients with lower limb arthroplasty (including hip or knee arthroplasty). METHODS: On December 15, 2021, we searched the relevant articles from the PubMed, Embase, Medline (via Ovid), China National Knowledge Infrastructure (CNKI) and Wan Fang Med Online databases. We used the Newcastle-Ottawa Scale (NOS) to assess the quality of the articles that met the exclusion and inclusion criteria. R Studio was used to analyze the effect sizes (based on the random model integration) on the extracted data. Meanwhile, potential publication bias and sensibility analysis were performed. RESULTS: We included seven studies, which included a total of 460,594 patients, for quantitative analysis. Overall, frailty increased the risk of mortality in lower limb arthroplasty patients compared to those without frailty, as measured by a pooled risk ratio (RR) of 2.46 (95% confidence interval [CI]: 1.81-3.33). Additionally, subgroup analysis based on population revealed that the pooled RRs for total knee arthroplasty (TKA) patients in three studies and total hip arthroplasty (THA) patients in four studies were 2.61 (95% CI: 2.26-3.02) and 3.18 (95% CI: 1.92-5.28), respectively, for TKA patients in three studies and THA patients in four studies. Additionally, these statistically significant positive associations persisted in subgroup analyses by study design, geographic region, and follow-up period. CONCLUSION: Frailty is an independent risk factor for postoperative mortality in patients undergoing lower limb arthroplasty, according to our findings. This suggests that frailty may be a predictor of preoperative risk stratification for patients with such elective surgery and could alert doctors and nurses of early screening and medical care interventions in patients with such a need for surgery to reduce postoperative mortality in lower limb arthroplasty patients.

Aim: To systematically search ostomy clinical practice guidelines, critically assess their quality and clinical applicability of recommendations, and summarize the recommendations. Design: Systematic review. Data Sources: The PubMed, ProQuest and CINAHL databases, eight guideline databases, and three ostomy institution websites were searched on September 3, 2021. Review Methods: Appraisal of Guidelines for Research and Evaluation II (AGREE II) and AGREE Recommendation EXcellence (AGREE-REX) were used to assess the guideline. Results: The initial search identified 1475 documents. Of these, 27 full-text documents were reviewed. Finally, 10 guidelines were included. Among these, the 2019 Registered Nurses' Association of Ontario (RNAO) guidelines had the highest total scores using AGREE II and AGREE-REX. The 2019 National Institute for Health and Care Excellence (NICE) and 2018 European Hernia Society (EHS) were also ranked as high-quality and evaluated as "recommended." The median of the "applicability" domain was the lowest (45%) among the six AGREE II domains. The median of the "values and preferences" domain was the lowest (38%) among the three AGREE-REX domains. In total, 172 recommendations were summarized and parastomal hernia received the most attention among the recommendations. Conclusion: The quality of the 10 clinical practice guidelines varied widely. The three identified high-quality guidelines might be appropriate first choices in daily ostomy care and management practice and can be tailored to the local context. Ostomy guidelines require further improvement in the "applicability" and "values and preferences" domains. No Patient or Public Contribution: This review only searched and evaluated relevant documents, so such details do not apply to this review.
RESUMEN
Background: Identifying a high-risk group of older people before surgical procedures is very important. The study aimed to explore the association between the age-adjusted Charlson comorbidity index (ACCI) and all-cause mortality and readmission among older Chinese surgical patients (age ≥65 years). Methods: A large-scale cohort study was performed in 25 general public hospitals from six different geographic regions of China. Trained registered nurses gathered data on clinical and sociodemographic characteristics. All-cause mortality was recorded when patients died during hospitalization or during the 90-day follow-up period. Readmission was also tracked from hospital discharge to the 90-day follow-up. The ACCI, in assessing comorbidities, was categorized into two groups (≥5 vs. <5). A multiple regression model was used to examine the association between the ACCI and all-cause mortality and readmission. Results: There were 3,911 older surgical patients (mean = 72.46, SD = 6.22) in our study, with 1,934 (49.45%) males. The average ACCI score was 4.77 (SD = 1.99), and all-cause mortality was 2.51% (high ACCI = 5.06% vs. low ACCI = 0.66%, P < 0.001). After controlling for all potential confounders, the ACCI score was an independent risk factor for 90-day hospital readmission (OR = 1.18, 95% CI: 1.14, 1.23) and 90-day all-cause mortality (OR = 1.26, 95% CI: 1.16-1.36). Furthermore, older surgical patients with a high ACCI (≥5) had an increased risk of all-cause mortality (OR = 6.13, 95% CI: 3.17, 11.85) and readmission (OR = 2.13, 95% CI: 1.78, 2.56) compared to those with a low ACCI (<5). The discrimination performance of the ACCI was moderate for mortality (AUC:0.758, 95% CI: 0.715-0.80; specificity = 0.591, sensitivity = 0.846) but poor for readmission (AUC: 0.627, 95% CI: 0.605-0.648; specificity = 0.620; sensitivity = 0.590). Conclusions: The ACCI is an independent risk factor for all-cause mortality and hospital readmission among older Chinese surgical patients and could be a potential risk assessment tool to stratify high-risk older patients for surgical procedures.
RESUMEN
Stroke patients tend to suffer from immobility, which increases the possibility of post-stroke complications. Urinary tract infections (UTIs) are one of the complications as an independent predictor of poor prognosis of stroke patients. However, the incidence of new UTIs onsets during hospitalization was rare in most datasets with a prevalence of 4%. This imbalanced data distribution sets obstacles to establishing an accurate prediction model. Our study aimed to develop an effective prediction model to identify UTIs risk in immobile stroke patients, and (2) to compare its prediction performance with traditional machine learning models. We tackled this problem by building a Siamese Network leveraging commonly used clinical features to identifying patients with UTIs risk. Model derivation and validation were based on a nationwide dataset including 3982 Chinese patients. Results showed that the Siamese Network performed better than traditional machine learning models in imbalanced datasets (Sensitivity: 0.810; AUC: 0.828).

Objective: Frailty is a common geriatric syndrome defined as multiple deficits, impairing the capacity to figure out insult. Previous studies have reported a significant association between frailty and mortality in stroke patients. This study aimed to explore the association between frailty and mortality among older Chinese stroke patients. Methods: This study was a secondary analysis of a multicenter prospective cohort study conducted in older Chinese inpatients from October 2018 to February 2020, and patients with a primary diagnosis of stroke including hemorrhage and ischemia, were included in our study. Frailty of older inpatients with stroke from six hospitals was measured by the FRAIL scale, and a one-year follow-up was performed by well-trained nurses of these hospitals via telephone. Multivariable logistic regression was used to detect the association between frailty and one-year mortality. Results: A total of 530 stroke patients with an average age of 72.94 (SD = 5.79) years were included in the present study. There were 37 (7.0%) hemorrhagic strokes and 493 (93.0%) ischemic strokes, with 228 (43.0%) females in this population. The prevalence of frailty was 22.5%. In the logistic regression model with adjustment for age, sex, instrumental activities of daily living (IADL), basic activities of daily living (ADL), education, history of falls, BMI, smoking, alcohol consumption, low handgrip strength, type of stroke and polypharmacy, stroke patients with frailty had an increased risk of one-year mortality compared to those without frailty (OR = 3.38, 95% CI: 1.22-9.37, P = 0.019). Conclusion: Our study indicated that frailty was an independent risk factor for one-year all-cause mortality among older stroke patients in China. Frailty may be an essential factor for clinicians to consider before making a comprehensive treatment, and corresponding mixed interventions, including exercise training and nutritional programs, need to be conducted among older stroke patients.
