Ethical climate, moral resilience, and ethical competence of head nurses.

BACKGROUND: The ethical competence of head nurses plays a pivotal role in nursing ethics. Ethical climate is a prerequisite for ethical competence, and moral resilience can positively influence an individual's ethical competence. However, few studies have focused on the relationship between ethical climate, moral resilience, and ethical competence among them. OBJECTIVES: To investigate the relationship between ethical climate, moral resilience, and ethical competence, and examine the mediating role of moral resilience between ethical climate and ethical competence among head nurses. DESIGN: A quantitative, cross-sectional study. METHODS: A total of 309 Chinese head nurses completed an online survey, including ethical climate questionnaire, Rushton moral resilience scale, and ethical competence questionnaire. Inferential statistical analysis includes Pearson's correlation and a structural equation model. ETHICAL CONSIDERATIONS: This study received ethical approval from the Institutional Review Board of Xiangya Nursing School of Central South University (No. E2023146). RESULTS: Head nurses' ethical climate score positively impacted ethical competence (r = 0.208, p < .001), and ethical climate could affect ethical competence through the mediating role of moral resilience. CONCLUSION: This study emphasized the value of ethical climate in moral resilience of head nurses, ultimately leading to an enhancement in their ethical competence.

Association of nurse managers' paternalistic leadership and nurses' perceived workplace bullying: The mediating effect of organizational climate.

AIMS: To explore the association between nurse managers' paternalistic leadership and nurses' perceived workplace bullying (WPB), as well as to examine the mediating role of organizational climate in this association. BACKGROUND: There is a lack of empirical evidence regarding the relationship between nurse managers' paternalistic leadership, organizational climate and nurses' perceived WPB. Clarifying this relationship is crucial to understand how paternalistic leadership influences WPB and for nursing managers to seek organizational-level solutions to prevent it. METHODS: A cross-sectional survey was performed from 4 January to 10 February 2022, in six tertiary hospitals in mainland China. Demographic information, Paternalistic Leadership Scale, Organizational Climate Scale and Negative Acts Questionnaire-Revised were used in the survey. Descriptive statistics, Spearman correlation analyses and a structural equation model were used for data analysis. RESULTS: A total of 5093 valid questionnaires were collected. Moral leadership and authoritarian leadership have both direct and indirect effects on WPB through the mediating effect of organizational climate. The former is negatively related to WPB and the latter is positively related to WPB. Benevolent leadership was only negatively associated with WPB via the mediating effect of organizational climate. CONCLUSION: The three components of paternalistic leadership have different effects on WPB through the mediating effect of organizational climate. Nurse managers are recommended to strengthen moral leadership, balance benevolent leadership, reduce authoritarian leadership and strive to create a positive organizational climate in their efforts to mitigate WPB among nurses. IMPACT: This study enhanced our comprehension of the relationship between different leadership styles and WPB. Greater emphasis should be placed on moral leadership in the promotion of nursing managers and nursing leadership training programs. Additionally, nursing managers should focus on establishing a positive organizational climate that helps to reduce WPB. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution. This study did not involve patients, service users, caregivers or members of the public.

Dose-response relationships of resistance training in Type 2 diabetes mellitus: a meta-analysis of randomized controlled trials.

Background: Globally, type 2 diabetes mellitus (T2DM) accounts for approximately 90% of diabetes cases. Resistance training (RT) is frequently employed to diminish Glycated Hemoglobin (HbA1c) and Fast Blood Glucose (FBG) levels in T2DM patients. Yet, the specific dose-response relationships between RT variables such as training duration, frequency, and intensity for T2DM remain under-researched. Objectives: This meta-analysis aimed to elucidate the overarching effects of RT on HbA1c and FBG metrics and to provide dose-response relationships of RT variables. This was achieved by examining randomized controlled trials (RCTs) that reported reductions in HbA1c and FBG among T2DM patients. Methods: Comprehensive literature searches were conducted up to 25th February 2023 across databases including EMBASE, Pubmed, Cochrane, CENTRAL, Web of Science, CNKI, Wanfang Data, VIP Database for Chinese Technical Periodicals, and the Chinese Biomedical Database. The Physical Therapy Evidence Database (PEDro) was leveraged to appraise the quality of selected studies based on predefined inclusion and exclusion criteria. The meta-analysis was conducted using Stata 16. Results: 26 studies that include 1336 participants met the criteria for inclusion. RT significantly reduced HbA1c and FBG levels in comparison to control groups (P<0.05). Meta-regression analyses revealed that the number of repetitions per set (p=0.034) was a significant predictor of RT's efficacy on HbA1c. Subgroup analyses indicated that the most pronounced reductions in HbA1c and FBG occurred with a training duration of 12-16 weeks, intensities of 70-80% of 1 RM, training frequencies of 2-3 times per week, 3 sets per session, 8-10 repetitions per set, and less than a 60-second rest interval. Conclusion: The beneficial impact of RT on HbA1c and FBG in T2DM patients is affirmed by this systematic review and meta-analysis. Moreover, the critical training parameters identified in this study are pivotal in enhancing HbA1c and FBG reductions, providing a reference for clinical staff to formulate RT exercise regiments for T2DM patients.

DESIGN: Using CiteSpace software, a visual analysis of 1288 included articles related to hypothermia in surgical patients was performed. METHODS: CiteSpace software is a Java application that supports knowledge research, data visualization and analysis of literature databases. The following data were retrieved: title, abstract, year, keywords, author, academic institution, journal and citations. The included literature was analysed using CiteSpace visualization software, knowledge mapping, collaborative network analysis, cluster analysis and highlighting keywords for visualization. RESULTS: A total of 1288 articles related to hypothermia in surgical patients were included, with the largest number of articles published in the United States (448), followed by in Germany (104) and China (102). The top three institutions, journals and authors were from the United States. The most common keywords were perioperative 'hypothermia', 'risk factors' and 'anesthesia'.

Risk Factors for Postoperative Puncture Site Bleeding after Interventional Treatment of Cerebrovascular Disease via Common Femoral Artery Puncture: A Retrospective Analysis of 710 Cases.

This study aimed to identify the risk factors associated with puncture site bleeding following percutaneous puncture of the common femoral artery during interventional treatment of cerebrovascular disease (CVD). A retrospective analysis was conducted on 710 patients who underwent interventional treatment for CVD via femoral artery puncture. Among them, 26 individuals (3.66%) experienced bleeding at the femoral artery puncture site. Binary logistic regression analysis was performed to identify risk factors for puncture site bleeding. The impact of salt bag compression on postoperative bleeding was evaluated in patients with intermediate to high bleeding risk scores. The bleeding group showed higher blood pressure, lower platelet counts, longer prothrombin time and activated partial thromboplastin time, as well as a higher prevalence of larger vascular sheath sizes and variations in the timing of anti-coagulant and anti-platelet therapy administration. The bleeding risk score was higher in the bleeding group, indicating its predictive value for bleeding risk. Higher bleeding risk score, unstable blood pressure, repeated puncture, and serious vascular conditions were significant risk factors for puncture site bleeding. Application of salt bag compression for a duration of 2 hours reduced postoperative puncture site bleeding in patients with intermediate to high bleeding risk scores. Our study identified several significant risk factors for puncture site bleeding after cerebral vascular intervention via femoral artery puncture, including the bleeding risk score, blood pressure, repeated puncture, and vascular conditions. Implementing salt bag compression as a preventive measure can help mitigate bleeding complications in these high-risk patients.

Experiences of healthcare workers following occupational exposure to COVID-19 at the early stages of the pandemic: A phenomenological qualitative study.

AIM: To explore the experiences of healthcare workers (HCWs) following occupational exposure to coronavirus disease 2019 (COVID-19) during the early stage of the pandemic. DESIGN: A Husserl descriptive phenomenological study design was employed. METHODS: Convenient and snowball sampling was used. In-depth semi-structured telephone interviews were conducted from February to March 2020 with the frontline HCWs who were exposed to COVID-19 during work. Data analysis was conducted following the 7-step analysis method developed by Colaizzi. RESULTS: Fifteen HCWs participated in the study. Four themes were identified, including (1) traumatic experiences since the occupational exposure; (2) getting through the hard time; (3) struggling to return to work; (4) reflections on occupational exposures. CONCLUSION: The HCWs had traumatic and painful experiences after the occupational exposure. But they returned to work with strong resilience, professional obligation and social support. Training and supervision, and adequate supply of personal protective equipment are suggested to prevent professional exposure. Social and organizational support should be provided for the exposed HCWs.

Evaluation of Comfort in Patients with Intestinal Fistula and Analysis of Influencing Factors.

Objective: To analyze the comfort and influencing factors in patients with enterocutaneous intestinal fistula (ECF) on hospital admission and propose targeted nursing intervention countermeasures. Methods: A total of 193 patients with EDF admitted to Hunan Provincial People's Hospital in China from May 2018 to February 2021 were selected for this study. Basic patient data were collected upon admission and the Kolcaba Comfort Scale was used to score comfort status. Univariate and multivariate analysis methods were used to analyze the influencing factors. Results: Patients with ECF have low comfort scores; the social, psychological, physiological and environmental dimensions were affected by 8, 7, 4 and 2 factors, respectively. The number of fistulas and skin condition in patients with ECF were the main physiological factors affecting patients. Conclusion: Paying attention to the fistula and surrounding skin care and strengthening psychological counseling can improve the comfort of patients with ECF.

Influences of Heider Balance on Knowledge, Attitude, Practice, and Quality of Life in Bladder Cancer Patients after Urinary Diversion.

Objective: To explore the influences of Heider balance on knowledge, attitude, practice (KAP), and quality of life in bladder cancer patients after urinary diversion. Methods: A set of bladder cancer patients after urinary diversion in our hospital from January 2016 to December 2020 were included in this study. Patients who received out-hospital intervention based on Heider balance were included in the observation group (85 cases). Meanwhile, patients who received routine out-hospital intervention were included in the control group (85 cases), and these patients matched with the observation group by gender, age, and education level. The scores of KAP, WHO quality of life-100 (WHOQOL-100) before discharge and at 6 months after discharge, and the rate of complications were compared in the two groups. Results: At 6 months after discharge, the score of these items of KAP including basic knowledge of disease, procedure of pouch replacement, dealing with pouch leakage, skin care of stoma, purchase and storage of pouch, dealing with stoma complications, optimistic mentality for disease, optimistic mentality for stoma, trust in medical staff, willingness to correct bad habits, confidence in maintaining health behavior, maintaining in health dietary habit, maintaining in health behavior, learning from relevant books, learning from relevant videos, experienced in pouch replacement, and experienced in care of stoma of the observation group were significantly higher than those of the control group (t = 6.144, 9.366, 3.129, 3.809, 4.173, 5.923, 2.788, 8.871, 3.291, 10.797, 7.067, 7.805, 3.828, 9.454, 2.827, 4.059, and 8.662, respectively, all P < 0.05). The scores of 16 items of WHOQOL-100 such as energy and fatigue, sleep and rest, positive feelings, thinking, learning, memory and concentration, self-esteem, body image and appearance, negative feelings, mobility, activities of daily living, dependence on medical support, personal relationships, social support, health and social care: availability and quality, opportunities to get new information/skills, opportunities for recreation and leisure, and quality of life from viewpoint in the observation group were significantly higher than those in the control group (t = 2.666, 2.571, 2.961, 3.453, 4.279, 2.781, 3.775, 4.807, 5.850, 4.194, 3.324, 3.873, 5.118, 3.244, 2.956, and 4.218, respectively, all P < 0.05). The rate of complications of the observation group was significantly lower than that of the control group (x 2 = 5.829, P < 0.05). Conclusion: The Heider balance can help to reduce the rate of complications, improve knowledge, attitude, practice, and quality of life in urinary diversion patients. These merits make it an attractive approach in guidance of out-hospital intervention.

Depicting the Implication of miR-378a in Cancers.

MicroRNA-378a (miR-378a), including miR-378a-3p and miR-378a-5p, are encoded in PPARGC1B gene. miR-378a is essential for tumorigenesis and is an independent prognostic biomarker for various malignant tumors. Aberrant expression of miR-378a affects several physiological and pathological processes, including proliferation, apoptosis, tumorigenesis, cancer invasion, metastasis, and therapeutic resistance. Interestingly, miR-378a has a dual functional role in either promoting or inhibiting tumorigenesis, independent of the cancer type. In this review, we comprehensively summarized the role and regulatory mechanisms of miR-378a in cancer development, hoping to provide a direction for its potential use in cancer therapy.

Correlation Analysis Between Required Surgical Indexes and Complications in Patients With Coronary Heart Disease.

A total of 215 patients with coronary heart disease (CHD) were analyzed with SPSS. Samples of different genders showed significance in the obtuse marginal branch of the left circumflex branch × 1, the diagonal branch D1 × 1, and the ms PV representation. Patients with left circumflex branch occlusion are more male and tend to be younger. Age displayed a positive correlation with left intima-media thickness (IMT) and right IMT. This indicated that as age increases, the values of left IMT and right IMT increase. Samples of different CHD types showed significance in the obtuse marginal branch of the left circumflex branch × 1, the middle part of RCA × 1, and the middle part of the left anterior descending branch × 1.5. For non-ST-segment elevation angina pectoris with acute total vascular occlusion, the left circumflex artery is the most common, followed by the right coronary artery and anterior descending branch. Ultrasound of carotid IMT in patients with CHD can predict changes in left ventricular function, but no specific correlation between left and right common carotid IMT was found. Samples with or without the medical history of ASCVD showed significance in the branch number of coronary vessel lesions. The value of the branch number of coronary vessel lesions in patients with atherosclerotic cardiovascular disease (ASCVD) was higher than in those without ASCVD. The occurrence of complication is significantly relative with the distance of left circumflex branch × 1, the middle segment of left anterior descending branch × 1.5, and the distance of left anterior descending branch × 1. For patients without complications, the values in the distal left circumflex branch × 1, the middle left anterior descending branch × 1.5, and the distal left anterior descending branch × 1 were higher than those for patients with complications. The VTE scores showed a positive correlation with the proximal part of RCA × 1, the branch number of coronary vessel lesions, the posterior descending branch of left circumflex branch × 1, the distal part of left circumflex branch × 1, and the middle part of left anterior descending branch × 1.5.

Clinical Significance of Pim-1 in Human Cancers: A Meta-analysis of Association with Prognosis and Clinicopathological Characteristics.

BACKGROUND: Pim-1 is overexpressed in cancer tissues and plays a vital role in carcinogenesis. However, its clinical significance in cancers is not fully verified by meta-analysis, especially in relation to prognosis and clinicopathological features. METHODS: Four databases, PubMed, Embase, Cochrane Library, and Web of Science, were searched. Literature screening and data extraction according to the inclusion and exclusion criteria. The quality of the included literatures was evaluated using the Newcastle-Ottawa scale and the data analysis was performed using STATA and Review Manager software. RESULTS: 15 articles were finally included for meta-analysis, involving 1651 patients. Effect-size pooling analysis showed that high Pim-1 was related to poor overall survival (OS) (HR 1.68 [95% CI 1.17-2.40], P = .004) and disease-free survival (DFS) (HR 2.15 [95 %CI 1.15-4.01], P = .000). Subgroup analysis indicated that the detection techniques of Pim-1 were the main sources of heterogeneity, and 2 literatures using quantitative polymerase chain reaction (qPCR) for Pim-1mRNA had high homogeneity (I2 = .0%, P = .321) in OS. Another 13 studies that applied immunohistochemistry (IHC) for Pim-1 protein had significant heterogeneity (I2=82.2%, P = .000; I2=92%, P = .000) in OS and DFS, respectively, and further analysis demonstrated that ethnicity, sample size, and histopathological origin were considered to be the main factors affecting their heterogeneity. In addition, high Pim-1 was associated with lymph node metastasis (OR 1.40 [95% CI 1.02-1.92], P = .04), distant metastasis (OR 2.69 [95%CI 1.67-4.35], P < .0001), and clinical stage III-IV (OR .7 [95% CI .50-.96, P = .03). Sensitivity analysis suggested that the pooled results of each effect-size were stable and reliable, and there was no significant publication bias (P = .138) in all included articles. CONCLUSION: High Pim-1 can not only predict poor OS and DFS of cancer, but also help to infer the malignant clinical characteristics of tumor metastasis. Pim-1 may be a potential and promising biomarker for early diagnosis, prognostic analysis and targeted therapy of tumors.

Analysis of Targeted Post-operative Nursing Outcome in 1246 Patients with Percutaneous Transhepatic Biliary Drainage.

Jaundice is a detection index in many disease conditions commonly characterized by yellowish staining of the skin and mucous membranes. This work studies the postoperative care outcome in 1,246 patients (669 males and 577 females) with obstructive jaundice who underwent percutaneous transhepatic biliary drainage (PTBD). These patients were admitted to the interventional vascular surgery department of our hospital from February 2017 to February 2022. From the results, frequent wound re-dressing and maintenance of the drainage tube had significant positive influence on wound healing and patient recovery. The data also showed strict adherence by patients to the doctor's recommendation advising them to visit the interventional specialist care clinic in time for wound dressing change and drainage tube maintenance. As a result, there was no significant difference in wound allergy, exudation, redness and loosening among patients. A cross-sectional analysis of the effect of age on recovery revealed variations in the healing pattern (wound loosening and the redness) between patients of different ages although the relationship is not very clear due to the limited sample size. Efficient drainage tube maintenance promoted recovery and prevented the occurrence of related complications such as PTBD tube blockage and biliary tract infection. The establishment of the interventional specialist care clinic used in this study additionally ensures patients' safety, and the incidence of complications have been reduced drastically. These achievements are attributable to the implementation of regular dressing change, drainage tube maintenance and health education for patients with PTBD tube. These practices have also improved on the level of specialty in nursing practice, increased the professional value of nurses and better recognition by the society.

Immediate enteral nutrition can accelerate recovery and be safe in mild acute pancreatitis: A meta-analysis of randomized controlled trials.

OBJECTIVES: The effect of early enteral nutrition (EN) in patients with acute pancreatitis (AP) has been confirmed. In recent years, some researchers provided new strategy that immediate EN was offered after admission. The effect and safety of immediate EN was unclear because of the different results among studies. The study aimed to implement the meta analysis of randomized controlled trials (RCT) to confirm the effect and safety between the immediate EN group and the early refeeding group. METHODS: Four electronic databases including PubMed, EMBASE, the Cochrane Library and China National Knowledge Internet (CNKI) were searched from inception to July 2021. Endnote X7.0 software was used to manage all the relevant citations. Then data extraction and evaluation of risk of bias for included studies were performed after initial selection and full-text selection. All statistical analyses were performed by Review Manager 5.3 version software. RESULTS: 5 randomized controlled trials (RCT) involving 372 patients were included in the present study. The meta analysis revealed that immediate EN after admission in patients with AP could significantly decrease the length of hospital stay (LOHS) (Mean difference [MD] = 2.57, 95% confidence interval [CI] = 0.41-4.72) and the intolerance of feeding (risk ratio [RR] = 0.78, 95%CI = 0.63-0.95), compared with early refeeding. But immediate EN couldn't significantly decrease the incidence of readmission after discharging (RR = 0.51, 95%CI = 0.12-2.27), the incidence of progression to severe pancreatitis (RR = 0.76, 95%CI = 0.15-3.76), the incidence of complications (RR = 1.12, 95%CI = 0.50-2.49) and the values of C-reactive protein (CRP) and leukocyte counts (MD = 1.05, 95%CI = 0.15-2.26 and MD = 0.11, 95%CI = 0.59-0.80), compared with early refeeding. CONCLUSIONS: Compared with early refeeding, immediate EN after admission could safely reduce LOHS and intolerance of feeding in patients with AP.

Intermittent Fasting in Weight Loss and Cardiometabolic Risk Reduction: A Randomized Controlled Trial.

BACKGROUND: Intermittent fasting is an effective approach to promote weight loss. The optimal model of intermittent fasting in achieving weight management and cardiometabolic risk reduction is an underexplored but important issue. PURPOSE: This study was designed to examine the effects of alternate-day fasting (ADF) and 16/8 time-restricted fasting (16/8 TRF) on weight loss, blood glucose, and lipid profile in overweight and obese adults with prediabetes. METHODS: A randomized controlled trial was conducted on a sample of 101 overweight and obese adults with prediabetes. The participants were randomized into the ADF group (n = 34), 16/8 TRF group (n = 33), and control group (n = 34). The intervention lasted for 3 weeks. Data on body weight, body mass index, waist circumference, blood glucose, and lipid profile were collected at baseline, at the end of the intervention, and at the 3-month follow-up. RESULTS: The reductions in body weight, body mass index, and waist circumference in the ADF and 16/8 TRF groups were more significant than those in the control group across the study period (all ps < .05). Moreover, significant reductions on blood glucose and triglycerides were observed in the two intervention groups as well. Furthermore, the reductions in body weight and body mass index in the ADF group were more significant than those in the 16/8 TRF group (all ps < .001). However, differences on the changes in blood glucose, waist circumference, and low-density lipoprotein cholesterol between the two intervention groups were not significant. CONCLUSIONS/IMPLICATIONS FOR PRACTICE: The benefits of ADF and 16/8 TRF in promoting weight loss in overweight/obese adults with prediabetes were shown in this study. ADF was shown to have more-significant reduction effects on body weight and body mass index than 16/8 TRF. These findings indicate the potential benefit of integrating intermittent fasting regimens into normal dietary patterns to reduce the risk of diabetes and cardiovascular disease in this population.

ABCDEF pulmonary rehabilitation program can improve the mid-term lung function of lung cancer patients after thoracoscopic surgery: A randomized controlled study.

Background Pulmonary rehabilitation is recommended for most patients with lung diseases. However, some previous studies have shown that pulmonary rehabilitation has no obvious effect on short-term lung function in patients with lung cancer. Objective The purpose of this study was to evaluate the effect of the ABCDEF pulmonary rehabilitation program on lung cancer patients who have undergone surgery. Design This was a randomized controlled trial with repeated measures. Settings The study was conducted in the Cardiothoracic Surgery Department of a 4000-bed comprising training and research hospital from 2019 to 2020. Participants A total of 90 patients who underwent thoracoscopic pneumonectomy were divided into two groups of 45, using a completely randomized model. Methods Patients in the experimental group participated in an ABCDEF program (Acapella positive vibration pressure training, breathing exercise, cycling training, dance in the square, education, and follow-up) after surgery. In contrast, the regular care provided to the control group focused on breathing and expectoration guidance. The study outcomes were the first second (FEV1), forced vital capacity (FVC), FEV1/FVC ratio, 6 min walking distance, Borg score, incidence of postoperative complications, length of indwelling chest tube, and length of postoperative stay. Generalized estimating equation models were used to compare the changes in the outcomes between the groups over time. Results The ABCDEF pulmonary rehabilitation program for patients who underwent thoracoscopic pneumonectomy was found to be more effective in increasing lung function at 3 months after discharge (p<0.05). However, there was no statistically significant difference on the day of discharge (p>0.05). Exercise tolerance was different at both time points (p<0.05). The incidence of postoperative complications in the experimental group was lower than that in the control group (p<0.05). The length of postoperative stay in the experimental group was also shorter (p<0.05), however, the length of the indwelling chest tube was not significantly different between the intervention and control groups (p>0.05). Conclusions This study showed that the ABCDEF pulmonary rehabilitation program could effectively improve mid-term lung function and exercise tolerance in patients after thoracoscopic pneumonectomy, and reduce the incidence of postoperative complications along with the length of postoperative hospital stay.

A systematic review and meta-analysis of the effect of resistance exercise therapy on the prognosis of patients after percutaneous coronary intervention.

BACKGROUND: Exercise rehabilitation therapy after percutaneous coronary intervention (PCI) can accelerate physical recovery, improve cardiovascular work efficiency, and reduce the incidence of arterial restenosis. This study aimed to investigate the effect of resistance exercise therapy after PCI by literature search and meta-analysis. METHODS: The databases of Embase, Cochrane library, PubMed, and Ovid were searched for all published English language articles related to resistance exercise after PCI from January 2000 to January 2021. After screening the literature according to the inclusion and exclusion criteria and assessing the risk of bias, RevMan 5.4 software was used to analyze and obtain a forest plot and funnel plot. RESULTS: A total of 7 articles were included in this study for quantitative analysis, involving 776 patients all together. Meta-analysis showed that compared with conventional intervention methods, resistance exercise could reduce the maximum exercise load after PCI [mean difference (MD) =-25.27, 95% confidence interval (CI): -31.97 to -18.57, Z=7.39, P<0.00001], reduce the peak oxygen consumption of exercise after PCI (MD =-2.36, 95% CI: -3.09 to -1.64, Z=6.42, P<0.00001), increase left ventricular ejection fraction (LVEF; MD =4.06, 95% CI: 0.72 to 7.40, Z=2.38, P=0.02), increase the 6-minute walk distance (6MWD; MD =18.23, 95% CI: 0.22 to 36.23, Z=1.98, P=0.05), and improve the quality of life of patients after surgery (MD =5.81, 95% CI: 1.49 to 10.14, Z=2.63, P=0.008). DISCUSSION: Resistance training can improve the physical activity, cardiac function, and quality of life of patients after PCI.

Anxiety and depression levels of the general population during the rapid progressing stage in the coronavirus disease 2019 outbreak: a cross-sectional online investigation in China.

OBJECTIVE: The outbreak of COVID-19 has major impacts on the psychological health of the public. This study aimed to investigate the anxiety and depression levels of the general population during the rapid progressing stage of COVID-19 pandemic in China and to explore the associated factors. DESIGN AND SETTING: A cross-sectional online survey. PARTICIPANTS: 2651 Chinese people. MEASURES: The Hospital Anxiety and Depression Scale was used to measure their psychological health. A structured questionnaire collected possible associated factors, including sociodemographic characteristics, health information, contact history-related information, experience and perceptions, knowledge and education and adopted precautions. Multiple linear regression was conducted to explore the factors associated with anxiety and depression. RESULTS: The mean score of anxiety and depression was 4.35 and 4.38, respectively. The rates of people with anxiety and depressive symptoms (with >7 score in the subscale) were 14.15% and 17.35%, respectively. Participants without political party membership, with contact history of COVID-19, going out or gathering, taking Chinese medicine herbs, being unsatisfied with current precautions, perceiving higher risks of infection, lower knowledge and poorer health presented higher anxiety and depression levels. Moreover, those who were females, married, lived alone and wore mask were more anxious; whereas people who were younger, experienced public health crisis, did not take precautions (regular work-rest, exercise) had higher depression level. CONCLUSIONS: During the rapid progressing stage of COVID-19 pandemic in China, one-seventh and one-sixth respondents presented anxiety and depression symptoms, respectively. The risk factors for anxiety and depression included the following: without political party membership, with contact history of COVID-19, going out or gathering, wearing masks, taking Chinese medicine herbs, being unsatisfied with current precautions, perceiving higher susceptibility, lower knowledge and poorer health status. Extensive information and psychological support should be provided to improve the mental health of the general population.

Eriodictyol inhibits the growth of CNE1 human nasopharyngeal cancer growth by targeting MEK/ERK signalling pathway, inducing cellular autophagy and inhibition of cell migration and invasion.

PURPOSE: Eriodictyol is an active flavonoid present in several vegetables and fruits. Eriodictyol-bearing plants have long been used in folk medicine used to treat different human disorders. It has been reported to exhibit the anticancer, antioxidative and antiinflammatory properties. The current research study was designed to explore the anticancer potential of eriodictyol against CNE1 nasopharyngeal cancer (NP) cells. Additionally, its effects of targeting MEK/ERK signalling pathway, autophagy, cell migration and invasion were also examined. METHODS: MTT assay was applied for viability measurements, and clonogenic potency measurements were made by clonogenic assay. Autophagy was monitored by transmission electron microscopy (TEM). Cell migration capability was examined by wound healing assay, and transwell chambers assay was used for estimation of cell invasion. Western blotting assay was performed to examine protein expression levels. RESULTS: The results indicated the proliferation rate of CNE1 cells was reduced in eriodictyol dose-dependently. Cell colonies were also observed to be minimised after eriodictyol exposure. The underlying mechanism of antiproliferative effects of eriodictyol in the current research was found to be autophagy-mediated as suggested by TEM and increased expressions of pro-autophagy proteins. Cell migration and invasion was significantly suppressed by eriodictyol in CNE1 cells. Finally, western blotting assay indicated that eriodictyol blocked MEK/ERK signalling pathway dose-dependently. In conclusion, the results of the currently performed investigation indicated that eriodictyol is a potential anticancer agent against CNE1 nasopharyngeal cancer. CONCLUSIONS: Therefore, this molecule may prove a leading agent in nasopharyngeal cancer treatment provided further in vitro and in vivo investigations are performed.

Effects of alternate-day fasting on body weight and dyslipidaemia in patients with non-alcoholic fatty liver disease: a randomised controlled trial.

BACKGROUND: Alternate-day fasting (ADF) is a novel diet therapy that may achieve reduction in body weight and improvement of dyslipidaemia, but the impact of this diet on patients with non-alcoholic fatty liver disease (NAFLD) remains unknown. The aim of this study was to evaluate the effects of ADF on the body weight and lipid profile of individuals with NAFLD. METHODS: NAFLD patients (n = 271) were randomised to the ADF group, time-restricted feeding (TRF) group, or the control group and subjected to the respective diet for 12 weeks. Anthropometric measurements (body weight, fat mass/fat-free mass) were performed, and plasma lipids were analysed enzymatically. RESULTS: Within 4 weeks, the body weight decreased significantly (P < 0.001) in the ADF group by 4.56 ± 0.41 kg (6.1 ± 0.5%) and the TRF group by 3.62 ± 0.65 kg (4.83 ± 0.9%) compared to the control group, and it decreased even more after 12 weeks in both groups (ADF: - 4.04 ± 0.54 kg, 5.4 ± 0.7%; TRF: - 3.25 ± 0.67 kg, 4.3 ± 0.9%). Fat mass was significantly reduced by ADF (- 3.49 ± 0.37 kg; 11 ± 1.2%) and TRF (- 2.91 ± 0.41 kg; 9.6 ± 1.3%), with ADF leading to a further reduction in fat mass after 12 weeks (- 3.48 ± 0.38 kg; 11 ± 1.2%). Total cholesterol was significantly decreased at both time points in the ADF group (- 0.91 ± 0.07 mmol/L; 18.5 ± 1.5%) compared to the control and TRF groups. Both ADF (- 0.64 ± 0.06 mmol/L; 25 ± 1.9%) and TRF (0.58 ± 0.07 mmol/L; 20 ± 1.7%) achieved a significant reduction in serum triglycerides (P < 0.001) after 12 weeks. Changes in fat free mass, HDL, LDL, fasting insulin, glucose, liver stiffness, and systolic or diastolic blood pressure did not differ between the groups. CONCLUSIONS: ADF appears to be an effective diet therapy for individuals with NAFLD that can achieve weight loss and improvement of dyslipidaemia within a relatively short period of time (4 to 12 weeks). Potential preventive effects of ADF on cardiovascular disease need to be confirmed by future investigations.

[Effect of bronchoalveolar lavage with fiberoptic bronchoscopy combined with vibration sputum drainage on mechanically ventilated patients with severe pneumonia: a prospective randomized controlled trial in 286 patients].

OBJECTIVE: To investigate the curative effect of bronchoalveolar lavage with fiberoptic bronchoscopy combined with vibration sputum drainage in the treatment of severe pneumonia patients undergoing mechanical ventilation (MV). METHODS: A prospective randomized controlled trial was conducted. 286 severe pneumonia patients undergoing MV admitted to intensive care unit (ICU) of Hunan People's Hospital from January 2014 to July 2016 were enrolled, and they were divided into control group and observation group according to random number table, with 143 patients in each group. Patients in both groups received sensitive antibiotics for anti-infection, etiological treatment, and calefacient and humidifying treatment. The patients in the control group received bronchoalveolar lavage with fiberoptic bronchoscopy, and those in the observation group received bronchoalveolar lavage combined with vibration sputum drainage. The parameters of respiratory function and inflammation before and after treatment, curative effect, and prognosis were compared between the two groups. RESULTS: (1) There were no significant differences in respiratory function parameters between the two groups before treatment, 2 hours after treatment, the parameters were improved in both groups. Moreover, oxygenation index (PaO2/FiO2) in observation group was significantly higher than that of control group [mmHg (1 mmHg = 0.133 kPa): 379.1±20.2 vs. 351.8±24.7], and arterial partial pressure of carbon dioxide (PaCO2) and airway resistance (Raw) were significantly lower than those of the control group [PaCO2 (mmHg): 36.5±5.8 vs. 45.3±6.9, Raw (cmH2O, 1 cmH2O = 0.098 kPa): 12.9±0.6 vs. 13.1±0.8, all P < 0.01]. (2) There were no significant differences in inflammation parameters between the two groups before treatment, 24 hours after intervention, which were significantly decreased in both groups. Moreover, white blood cell count (WBC), procalcitonin (PCT) and C-reactive protein (CRP) in the observation group were significantly lower than those of the control group [WBC (×109/L): 8.2±1.7 vs. 12.8±3.7, PCT (µg/L): 15.4±2.4 vs. 21.8±3.1, CRP (mg/L): 37.1±6.1 vs. 67.2±7.2, all P < 0.01]. (3) Compared with the control group, the treatment efficiency of observation group was improved [95.1% (136/143) vs. 87.4% (125/143)], the quantity of sputum excretion was increased (mL: 49.2±12.5 vs. 36.9±11.0), duration of MV and length of ICU stay were significantly shortened (days: 6.4±3.6 vs. 9.4±2.1, 8.6±5.7 vs. 12.4±4.6, both P < 0.01), however, there was no significantly statistical difference in 28-day mortality between control group and observation group [2.8% (4/143) vs. 2.1% (3/143), P > 0.05]. CONCLUSIONS: Compared with bronchoalveolar lavage with fiberoptic bronchoscopy alone, the treatment of bronchoalveolar lavage combined with vibration sputum drainage is more effective in sputum excretion for severe pneumonia patients undergoing MV, which could improve the respiratory function, reduce infection, shorten the duration of MV and the length of ICU stay, and improve the recovery.
