The mediating role of psychological needs on the relationship between perceived organizational support and work engagement.

AIM: To examine the mediating effect of basic psychological needs on the relationship between perceived organizational support and work engagement among nurses. BACKGROUND: The satisfaction of basic psychological needs is crucial for breeding and sustaining individuals' intrinsic motivation. Little is known about the underlying motivational mechanisms that explain the relationship among perceived organizational support, basic psychological needs, and work engagement in a nursing context. METHODS: This was a cross-sectional online survey. A sample of 858 nurses from 12 hospitals was surveyed on their perceived organizational support, basic psychological needs, and work engagement. Structural equation models and bootstrapping methods were used to examine the hypotheses. STROBE reporting guidelines were utilized. RESULTS: Perceived organizational support was positively associated with basic psychological needs and work engagement. Basic psychological needs were positively associated with work engagement. Basic psychological needs mediated the relationship between perceived organizational and work engagement. CONCLUSION: Perceived organizational support may enhance work engagement by fulfilling the basic psychological needs of nurses. IMPLICATIONS FOR NURSING AND NURSING POLICY: Basic psychological needs deserve more attention in nursing organizations. Managers should seek optimal strategies to fulfill nurses' needs for autonomy, competence, and relatedness to stimulate their intrinsic motivation to enhance work engagement.

Nurses' perceptions of career growth: A qualitative descriptive study.

AIMS: To explore nurses' experiences and perceptions of career growth and its influencing factors, as career growth is more closely associated with individual attitudes and behaviours in the new career era. DESIGN: A qualitative descriptive design was used. METHODS: Thirty-one nurses from 10 secondary and 8 tertiary hospitals in Sichuan Province of China were purposively selected to participate in this study. The data were collected using individual semi-structured face-to-face interviews. Two researchers independently reviewed the transcripts and emergent coding. The data were analysed using qualitative content analysis. FINDINGS: The nurses' perceptions of career growth fully described the nurses' experience and occurred in five dimensions: career promotion, career goal progress, professional ability and quality improvement, professional identity development and increase in personal prestige. The factors influencing career growth were identified at the organizational, individual and social levels. Career growth in nursing was complex, changed over time and showed several specific characteristics compared with other careers. The nurse-specific symbol of career growth was professional identity development, which reflected career progression characteristics. CONCLUSIONS: Career growth is a multi-dimensional concept with varying influencing factors. The meaning of career growth for nurses is distinct from that for employees in other careers. IMPACT: Nursing managers should guide nurses to comprehensively assess their career growth from multiple perspectives, and professional identity development deserves more attention. Both organizations and individuals should take responsibility for career management to pursue career growth.

[Clinical experience and academic thoughts of Professor LIU Feng-bin on case series of gastroesophageal reflux disease based on data mining].

To analyze and summarize Professor LIU Feng-bin's clinical experience and academic thoughts on gastroesophageal reflux disease (GERD), the study group adopted the retrospective study for case series and expert interview, extracted the retrospective data, including the herbs, diseases, syndrome type, medical expense and quantity of herbs of GERD patients attended the First Affiliated Hospital of Guangzhou University of Chinese Medicine. Statistical description and binary Logistic regression were used for the identification and modification of syndrome type and initial core herbs. After expert interviews were performed for the syndrome type and herbs, the final scheme were formed. A total of 112 GERD patients ages（48.97±13.13）y; male: 35 (31.3%), female: 77(68.7%) were enrolled. The numbers of patients with liver and stomach incoordination syndrome, heat stagnation of liver and stomach syndrome, syndrome of dual deficiency of Qi and Yin, syndrome of spleen deficiency and dampness-heat, spleen-stomach disharmony syndrome were 40, 26, 19, 17 and 10, respectively. The patients used totally 80 herbs, and 26 of them had significant differences among different syndrome groups. According to the logistic regression analysis on the 23 herbs used by 112 patients, the herbs scheme was modified for the second time. After the expert interviews and modification, the final consensus was reached. The main causes for GERD were dietary irregularities, moodiness, and weak constitution. The basic mechanism of GERD was spleen deficiency with Qi adverseness. The spleen-stomach disharmony syndrome was deleted by expert interviews. The 10 core herbs for GERD treatment were Taizishen(Pseudostellariae Radix), Fuling(Poria), Baizhu(Atractylodismacrocephalae Rhizoma), Gancao(Glycyrrhizae Radix Et Rhizoma), Zhebeimu(Fritillariae Thunbergii Bulbus), Haipiaoxiao(Sepiae Endoconcha), Zhiqiao(Aurantii Fructus), Chenxiang(Alosewood), Pugongying(Taraxaci Herba), Zhizitan(Cape Jasmine Fruit). The modification and psychological and diet interventions were also identified. This study summarized Professor LIU Feng-bin's clinical experience and academic thoughts of chronic atrophic gastritis based on data mining of case series and expert interviews. The quality of methodologies and report were both well. The results provide a foundation and ideas for further study on the complex intervention for GERD, and can be directly applied in clinical practice.

Studies on anti-angiogenesis of ginsenoside structure modification HRG in vitro.

This study investigates the anti-angiogenic effect of 3ß, 12ß, 20(S)-trihydroxy dammarane-3-O-ß-d-glucopyranosyl(1-2)-ß-d-glucopyranoside(HRG), a new chemical compound obtained by structure modification on Ginseng saponins Rg3, associated with the regulation of matrix metalloproteinases(MMPs) and its upstream signal-regulated molecule of vascular endothelial growth factor(VEGF) and basic fibroblast growth factor(b-FGF) in vitro, which plays an critical role in angiogenesis during the process of carcinoma. In our study, to investigate the anti-angiogenesis effect of HRG in HUVECs, we utilized cell proliferation assay, tube formation assay, wound-healing assay, Semi-quantitative reverse transcription PCR, and Western blot assay. Our results demonstrated that HRG plays a major role in the regulation of proliferation, migration and tube formation of HUVECs by suppressing the expression of VEGF and b-FGF in both transcriptional and post-transcriptional levels. In addition, the expression of MMP-2 and MMP-9, which were related to the ECM degradation, were down-regulated after administration of HRG as well. Overall, our results revealed that HRG strongly inhibited the process of angiogenesis and shows better effectiveness than Rg3.

[Effects of Nurse-Led Team Management on Type 2 Diabetes Patients in the Community].

BACKGROUND: Managing increasing numbers of diabetic patients is placing increasing pressure on healthcare providers, especially general practitioners, who usually serve in multiple roles. This situation has caused generally poor results in terms of diabetes management. However, community nurses in some countries have successfully and effectively controlled chronic diseases among their patients. Therefore, the effects of nurse-led management is worth further exploration in order to better understand and promote this mode of care. PURPOSE: To explore the effects of community-nurse-led team management on diabetes patients. METHODS: An experimental research design was adopted. Patients with type 2 diabetes were recruited from two community health centers (the first for the intervention group, the second for the control group) in Wuhou District, Chengdu City, China. The intervention group received nurse-led team management care for 2 years, while the control group received standard care. The evaluations were conducted before the intervention and at 6, 12, and 24 months into the intervention. Outcomes included glycosylated hemoglobin (HbA1c) level, body mass index, waist circumference, visual acuity, ankle brachial index, kidney function index, urinary protein level, and electrocardiogram. RESULTS: The 179 participants included 88 in the intervention group and 91 in the control group. After the intervention, HbA1c level, ankle brachial index, and waist circumference were all significantly better in the intervention group than in the control group (F = 28.894, p < .01; F = 4.065, p < .01; F = 5.540, p < .01). The other outcome variables remained statistically similar between both groups throughout the study period. CONCLUSIONS: Community nurse-led team management is an effective mode of care in terms of controlling blood glucose control and preventing diabetes-related complications.

[Determination of eight active components in Radix Hedysari by HPLC and its cluster analysis].

An HPLC method was established for the determination of adenosine, γ-aminobutyric acid (GABA) and six flavonoids (calycosin-7-glucoside, ononin, calycosin, isoliquiritigenin, formononetin and medicarpin） in Radix Hedysari. The samples were extracted with methanol by refluxing for 4 h. The HPLC-DAD was performed on a Diamonsil C(18) column (250 mm × 4.6 mm, 5 µm) with acetonitrile-water as the mobile phase. The column temperature was at 40 ℃ and the flow rate was 1.0 m L·min(-1), while the temperature of drift tube was 110.5 ℃ and the nebulizing gas flow was 3.1 L·min-1 for the ELSD system. The results showed all the eight components had good linear relationships (r(2) =0.992 8-1.000 0) in the range of the test concentration. The RSD of precision, stability and repeatability were less than 2%.The average recovery rates were 96.78%-103.45%, and RSD were 0.29%-1.61%.The index component contents of Radix Hedysari form 24 different origins were determined and used as variable factors in clustering analysis. The results were classified into 2 groups basically in accordance with the regional cluster. And the consequence was in consistent with the results of principal component analysis. This HPLC method is simple, shows good sensitive and accurate, and provides the experimental basis for multi-index control of Radix Hedysari. Clustering analysis for Radix Hedysari quality control has a certain reliability and objectivity.

Prophylactic effectiveness of budesonide inhalation in reducing postoperative throat complaints.

Postoperative sore throat (POST) is one of the main postoperative complaints. This study was to evaluate the efficacy of budesonide inhalation suspension (BIS) in reducing the incidence and severity of POST. One hundred and twenty patients scheduled for thyroid surgery with general anesthesia were enrolled and randomized into three groups. Group A received 200 mcg BIS 10 min prior to the tracheal intubation and received the same treatment 6 and 24 h after extubation. Group B received 200 mcg BIS 6 and 24 h after extubation. Control group received the same scheduled treatment as Group A, but the BIS was replaced with 2 ml normal saline. The patients were evaluated for sore throat and hoarseness 1, 24 and 48 h after extubation. The status of laryngopharynx was also recorded. There was no statistically significant difference in the incidence of sore throat among three groups. However, hoarseness occurred significantly less frequently in Group A (P < 0.05). One hour after extubation, Group A exhibited significantly less severe sore throat and hoarseness compared to the other two groups (P < 0.05), which disappeared 24 h later. The mucositis scores of laryngopharynx at 1, 24 and 48 h post-extubation were significantly lower in Group A (P < 0.05). BIS can reduce the incidence and severity of the POST prophylactically.

[Discussion on polysaccharide determination methods in new Chinese drug research].

According to existing problems in polysaccharide determination methods in new Chinese drug applications, the method suitability, chemical reference selection, components interference and method research were introduced. The author suggests that suitable determination method should be selected according to the structure and property of the polysaccharide, and validated. Some influent factors should be examined to assure the accuracy of the method, such as the stability and using amount of the visualizing reagent, visualizing time, maximum detection wavelength etc. Monosaccharide and other water soluble components should be removed from polysaccharide sample, and suitable reference substance and detection wavelength should be selected. It should pay attention to mutual interference of neutral and acidic saccharide, and use inhibitor to eliminate the interference. Because the slopes of the standard curves are different for different monosaccharide, it is proposed that the types and ratios of the monosaccharide in heteroglycan should be understood, and mixed reference substance solution in the ratio is prepared for determination.

Predictive value of diaphragm ultrasound for mechanical ventilation outcome in patients with acute exacerbation of chronic obstructive pulmonary disease.

BACKGROUND: Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is often combined with respiratory failure, which increases the patient's morbidity and mortality. Diaphragm ultrasound (DUS) has developed rapidly in the field of critical care in recent years. Studies with DUS monitoring diaphragm-related rapid shallow breathing index have demonstrated important results in guiding intensive care unit patients out of the ventilator. Early prediction of the indications for withdrawal of non-invasive ventilator and early evaluation of patients to avoid or reduce disease progression are very important. AIM: To explore the predictive value of DUS indexes for non-invasive ventilation outcome in patients with AECOPD. METHODS: Ninety-four patients with AECOPD who received mechanical ventilation in our hospital from January 2022 to December 2023 were retrospectively analyzed, and they were divided into a successful ventilation group (68 cases) and a failed ventilation group (26 cases) according to the outcome of ventilation. The clinical data of patients with successful and failed noninvasive ventilation were compared, and the independent predictors of noninvasive ventilation outcomes in AECOPD patients were identified by multivariate logistic regression analysis. RESULTS: There were no significant differences in gender, age, body mass index, complications, systolic pressure, heart rate, mean arterial pressure, respiratory rate, oxygen saturation, partial pressure of oxygen, oxygenation index, or time of inspiration between patients with successful and failed mechanical ventilation (P > 0.05). The patients with successful noninvasive ventilation had shorter hospital stays and lower partial pressure of carbon dioxide (PaCO2) than those with failed treatment, while potential of hydrogen (pH), diaphragm thickening fraction (DTF), diaphragm activity, and diaphragm movement time were significantly higher than those with failed treatment (P < 0.05). pH [odds ratio (OR) = 0.005, P < 0.05], PaCO2 (OR = 0.430, P < 0.05), and DTF (OR = 0.570, P < 0.05) were identified to be independent factors influencing the outcome of mechanical ventilation in AECOPD patients. CONCLUSION: The DUS index DTF can better predict the outcome of non-invasive ventilation in AECOPD patients.

Phytophthora infestans field isolates from Gansu province, China are genetically highly diverse and show a high frequency of self fertility.

The genetic diversity of 85 isolates of Phytophthora infestans collected in 2007 from Gansu province in China was determined and compared with 21 isolates collected before 2004. Among them, 70 belonged to the A1 mating type and 15 were self-fertile (SF). The mitochondrial DNA haplotypes revealed both Ia (25%) and IIa (75%) haplotypes. Metalaxyl resistance occurred with high frequency (54%) in Gansu. Simple sequence repeat (SSR) genotyping revealed 26 genotypes (13 from the Tianshui region) among the 85 isolates, and 18 genotypes among the 21 isolates collected before 2004, without overlap in genotypes detected in the two groups. Cluster analysis showed clear subdivisions within the different mating type isolates. Among Gansu's isolates, Nei's and Shannon's diversity indices were highest in isolates collected in Tianshui where both A1 and SF isolates were found. Analysis of molecular variance of isolates from Gansu indicated that 51% and 49% of the variance was explained by within-area and among-area variance, respectively. The results suggest that the occurrence of SF isolates increases the risk of sexual reproduction, the formation of oospore as initial inocula in the field, and affects the genotypic diversity in the population.

Quality of life of elderly Chinese rectal cancer patients after preventative anal surgery: a cohort study.

BACKGROUND/AIM: To assess the QOL in rectal cancer patients after preventative anal operation and to discuss the influence of age on perceived quality of life. METHODOLOGY: A prospective study of 342 patients with rectal cancer from May 2011 to January 2012 in the gastrointestinal surgery department was randomly selected and divided into the elderly group and the young group, and the differences in their QOL assessed by the questionnaire QLQ-C30, after preventative anal surgery (7 days) were compared. RESULTS: A total of 207 patients met the study criteria and were divided into the elderly group (≥60 years, 107 cases) and the young group (<60 years, 100 cases). The incidences of complication with pneumonia (p=0.030), wound infection (p=0.024) and ileus (p=0.036) were higher in the elderly group. In the QLQ-C30 assessment, the physical function in the elderly group was worse (p=0.004). Additionally, the fatigue of symptom, sleep disturbance and poor appetite (p<0.001), and global quality of life (p=0.002) were worse in the elderly group too. However, the role and emotional function were better in the elderly group (p<0.001). CONCLUSIONS: The QOL in elderly patients is generally worse than young patients, and a targeted approach should be used.

Development and Psychometric Evaluation of the Career Growth Scale for Nurses.

PURPOSE: The purpose of this study was to develop the career growth scale for nurses (CGSN) and evaluate its psychometric properties. METHODS: This study was conducted in four phases: (1) creating a pool of potential items through a qualitative design; (2) developing a preliminary scale using a modified two-round Delphi process; (3) refining the preliminary scale to finalize the scale using a cross-sectional survey; and (4) evaluating the psychometric properties of the final scale using another cross-sectional survey. A sample of 858 registered nurses from 12 general hospitals was recruited for this study. RESULTS: The final scale consisted of 17 items categorized into three factors: career goal progress, professional ability and attribute improvement, and career promotion and prestige increase. The three factors accounted for 75.4% of the observed variance in career growth. The overall Cronbach's α was .96, and the intraclass correlation coefficient was .92. The content validity index was .97. Confirmatory factor analysis showed acceptable model fitness. CONCLUSIONS: These results showed that the CGSN has good psychometric properties and can be used to evaluate specific career growth among nurses. This new instrument can further help nurse managers and clinical nurses themselves assess career growth and identify unsatisfactory aspects of growth, thereby designing tailored training programs and evaluating the effectiveness of such interventions.

Development of prediction model of low anterior resection syndrome for colorectal cancer patients after surgery based on machine-learning technique.

BACKGROUND: Low anterior resection syndrome (LARS) is a common postoperative complication in patients with colorectal cancer, which seriously affects their postoperative quality of life. At present, the aetiology of LARS is still unclear, but some risk factors have been studied. Accurate prediction and early management of medical intervention are keys to improving the quality of life of such high-risk patients. OBJECTIVES: Based on machine-learning methods, this study used the follow-up results of postoperative patients with colorectal cancer to develop prediction models for LARS and conducted a comparative analysis between the different models. METHODS: A total of 382 patients diagnosed with colorectal cancer and undergoing surgery at West China Hospital from April 2017 to December 2020 were retrospectively selected as the development cohort. Logistic regression, support vector machine, decision tree, random forest and artificial neural network algorithms were used to construct the prediction models of the obtained dataset. The models were internally validated using cross-validation. The area under the curve and Brier score measures were used to evaluate and compare the differentiation and calibration degrees of the models. The sensitivity, specificity, positive predictive value and negative predictive value of the different models were described for clinical use. RESULTS: A total of 342 patients were included, the incidence of LARS being 47.4% (162/342) during the six-month follow-up. After feature selection, the factors influencing the occurrence of LARS were found to be location, distance, diverting stoma, exsufflation and surgical type. The prediction models based on five machine-learning methods all showed acceptable performance. CONCLUSIONS: The five models developed based on the machine-learning methods showed good prediction performance. However, considering the simplicity of clinical use of the model results, the logistic regression model is most recommended. The clinical applicability of these models will also need to be evaluated with external cohort data.

Injectable hydrogel made from antler mesenchyme matrix for regenerative wound healing via creating a fetal-like niche.

BACKGROUND: Scar formation and loss of cutaneous appendages are the greatest challenges in cutaneous wound healing. Previous studies have indicated that antler reserve mesenchyme (RM) cells and their conditioned medium improved regenerative wound healing with partial recovery of cutaneous appendages. AIM: To develop hydrogels from the antler RM matrix (HARM) and evaluate the effect on wound healing. METHODS: We prepared the hydrogels from the HARM via enzymatic solubilization with pepsin. Then we investigated the therapeutic effects of HARM on a full-thickness cutaneous wound healing rat model using both local injections surrounding the wound and topical wound application. RESULTS: The results showed that HARM accelerated wound healing rate and reduced scar formation. Also, HARM stimulated the regeneration of cutaneous appendages and blood vessels, and reduced collagen fiber aggregation. Further study showed that these functions might be achieved via creating a fetal-like niche at the wound site. The levels of fetal wound healing-related genes, including Collagen III and TGFß3 treated with HARM were all increased, while the expression levels of Collagen I, TGFß1, and Engrailed 1 were decreased in the healing. Moreover, the number of stem cells was increased in the fetal-like niche created by HARM, which may contribute to the regeneration of cutaneous appendages. CONCLUSION: Overall, we successfully developed an injectable hydrogel made from antler RM matrix for the regenerative repair of full-thickness cutaneous wounds. We uncovered the molecular mechanism of the hydrogels in promoting regenerative wound healing, and thus pave the way for HARM to be developed for the clinic use.

[Application of peripherally inserted central catheter for parenteral nutrition in critically ill neonates].

OBJECTIVE: To apply peripherally inserted central catheter (PICC) in critically ill neonates who require long-term parenteral nutrition. METHODS: A retrospective review of 98 critically ill neonates who had a PICC inserted and received long-term parenteral nutrition from March to December 2011 was performed. RESULTS: The PICC insertion succeeded in 74.5% (73/98) of the cases at the first attempt. The catheter remained for an average of (19.7 +/- 2.0) days. Of the 98 cases, 92 underwent planned extubation after enteral nutrition was fully established; 10 developed complications within the follow-up period of 956 days. The PICC-associated complications occurred at a rate of 10. 5 per 1000 catheter-days, including infection (n=0), phlebitis (n=1), accidental dislodgement (n=3), catheter occlusion (n=3), and hemorrhage in puncture point (n=3). CONCLUSION: PICC can be used as a safe venous access for critically ill neonates for long-term parenteral nutrition. PICC-associated complications can be reduced through improving nursing skills, especially for catheter-related infection.

Gene Expression Profiling of Glioblastoma to Recognize Potential Biomarker Candidates.

Glioblastoma is an aggressive malignant tumor of the brain and spinal cord. Due to the blood-brain barrier, the accessibility of its treatments still remains significantly challenging. Unfortunately, the recurrence rates of glioblastoma upon surgery are very high too. Hence, understanding the molecular drivers of disease progression is valuable. In this study, we aimed to investigate the molecular drivers responsible for glioblastoma progression and identify valid biomarkers. Three microarray expression profiles GSE90604, GSE50601, and GSE134470 containing healthy and glioblastoma-affected samples revealed overlapping differentially expressed genes (DEGs). The interrelational pathway enrichment analysis elucidated the halt of cell cycle checkpoints and activation of signaling pathways and led to the identification of 6 predominant hub genes. Validation of hub genes in comparison with The Cancer Genome Atlas datasets identified the potential biomarkers of glioblastoma. The study evaluated two significantly upregulated genes, SPARC (secreted protein acidic and rich in cysteine) and VIM (vimentin) for glioblastoma. The genes CACNA1E (calcium voltage-gated channel subunit alpha1 e), SH3GL2 (SH3 domain-containing GRB2-like 2, endophilin A1), and DDN (dendrin) were identified as under-expressed genes as compared to the normal and pan-cancer tissues along with prominent putative prognostic biomarker potentials. The genes DDN and SH3GL2 were found to be upregulated in the proneural subtype, while CACNA1E in the mesenchymal subtype of glioblastoma exhibits good prognostic potential. The mutational analysis also revealed the benign, possibly, and probably damaging substitution mutations. The correlation between the DEG and survival in glioblastoma was evaluated using the Kaplan-Meier plots, and VIM had a greater life expectancy of 60.25 months. Overall, this study identified key candidate genes that might serve as predictive biomarkers for glioblastoma.

Protective effects of Radix Isatidis polysaccharide ameliorates obesity via promotion AMPK pathway in high-fat-diet-induced obese rats and 3T3-L1 adipocyte cells.

OBJECTIVES: The purpose of this paper is to ascertain the effect and mechanism of Radix Isatidis polysaccharide (RIP) on obesity. METHODS: High fat diet (HFD)-induced obese rats and the MDI-induced 3T3-L1 adipocyte cells were established to evaluate the ameliorated obesity effect and mechanism from RIP. KEY FINDINGS: Experiments in vivo show that oral administration of RIP has significant preventive effects on HFD-induced obesity and metabolic disorders in rats. With treatment of RIP (20, 40 and 80 mg/kg BW), the body weight, fat accumulation, adipocyte cell size, serum lipid levels and antioxidant enzyme activity were progressively improved. On the other hand, the treatment of 3T3-L1 cells with RIP (25, 50 and 100 mg/L) led to a decrease in lipid accumulation and glucose consumption. In addition, during adipogenesis in 3T3-L1 cells, RIP remarkably down-regulated mRNA levels of peroxisome proliferator-activated receptor-γ (PPARγ), CCAAT/enhancer binding protein-α (C/EBPα), sterol regulatory element-binding protein-1c (SREBP-1c), fatty acid synthase (FAS), acetyl-CoA carboxylase and glycerol-3-phosphate dehydrogenase. Furthermore, after RIP treatment, the protein expression of PPARγ, C/EBPα, FAS, HMG-CoA reductase and acetyl-CoA synthetase-1 (AceCS1) were significantly decreased and the expression of p-AMPK was increased. CONCLUSION: These results highlight the potential of RIP for obesity interventions and suggest that RIP inhibited adipocyte differentiation and lipid synthesis by activating adenosine 5'-monophosphate (AMP)-activated protein kinase (AMPK) signalling pathway and down-regulating the expression of major adipogenic transcription factors, PPARγ, C/EBPα, etc.

Effects of mindfulness-based intervention on glycemic control and psychological outcomes in people with diabetes: A systematic review and meta-analysis.

AIMS/INTRODUCTION: Psychological therapies have showed benefits for both glycemic control and psychological outcomes in people with diabetes. However, the effects of mindfulness-based intervention (MBI) on glycemic control and psychological outcomes are inconsistent across studies, and the evidence for MBI has not been summarized. We aimed to identify the effects of MBI on glycemic control and psychological outcomes in people with diabetes by carrying out a systematic review and meta-analysis. MATERIALS AND METHODS: Six databases (Pubmed, Embase, CINAHL, Cochrane, Web of science and PsycINFO) were searched from inception to October 2019. Randomized controlled trials of MBI for people with type 1 and type 2 diabetes were included. Two authors independently extracted relevant data and assessed the risk of bias, with a third reviewer as arbitrator. Subgroup analyses and sensitivity analyses were also carried out. RESULTS: Eight studies with 841 participants met the eligibility criteria. Meta-analysis showed that MBI can slightly improve glycosylated hemoglobin (HbA1c; -0.25%, 95% confidence interval [CI] -0.43 to -0.07) and diabetes-related distress (-5.81, 95% CI -10.10 to -1.52) contribute to a moderate effect size in reducing depression (standardized mean difference -0.56, 95% CI -0.82 to -0.30) and stress (standardized mean difference -0.53, CI -0.75 to -0.31). Subgroup analyses showed greater HbA1c reductions in subgroups with baseline HbA1c levels <8% and follow-up duration >6 months. Mixed effects were observed for anxiety. CONCLUSIONS: MBI appears to have benefits on HbA1c, depression, stress and diabetes-related distress in people with diabetes. More rigorous studies with longer follow-up duration are warranted to establish the full potential of MBI.

Strategies and criteria targeting the reform and development for the teaching resource of nursing undergraduate: A multi-center cross-sectional study.

ABSTRACT: Teaching resource of nursing students play an important role in improving clinical performance, while there is a little know and dearth of the access and development criteria or guidance of teaching resources for nursing undergraduates.To develop the admission and development criteria of education resources for nursing undergraduates, and to explore and determine its composition and connotation.A cross-sectional survey has been used.A total of 22 Chinese nursing schools and affiliated teaching bases (hospitals and community health centers).A total of 20 nursing experts were consulted to develop the questionnaire of admission and development criteria of teaching resource for nursing undergraduates in China, and then 285 valid experts from 22 Chinese nursing schools and affiliated teaching bases (hospitals and community health centers) conducted the questionnaire survey to evaluate experts' consensus rate and view on the composition and connotation of the developed criteria.There were 6 domains and 43 items included in the admission and development criteria of teaching resource for nursing undergraduates, which domains included educational budget and allocation of resources, infrastructure, clinical teaching bases, books and information services, educational experts, and educational exchanges. The experts' consensus rate was more than 90.2%.The standard is helpful to guide the future admission and development of teaching resource for nursing undergraduates, and favor the education quality improvement of nursing undergraduates.

Asymmetry of Subthalamic Neuronal Firing Rate and Oscillatory Characteristics in Parkinson's Disease.

PURPOSE: The aim of this study was to compare the neuronal firing rate and oscillatory activity of the subthalamic nucleus (STN) between the more affected (MA) and the less affected (LA) hemispheres in Parkinson's disease (PD). PATIENTS AND METHODS: We recorded and analyzed the intra-operative microelectrode recordings (MER) from the STN of 24 PD subjects. Lateralized Unified Parkinson's Disease Rating Scale (UPDRS) III sub-scores (item 20-26) were calculated. The STN corresponding to the MA side was designated as the MA STN while the other side as the LA STN. Single unit characteristics including interspike intervals were identified and spectral analyses were assessed. Further, the mean spontaneous firing rate (MSFR) of neurons was calculated. The correlations between clinical symptoms and neuronal activity were analyzed. RESULTS: The firing rate in the MA and LA sides were 43.18 ± 0.74 Hz and 36.94 ± 1.32 Hz, respectively, with an increase of 16.9% in the MA group. The number of neurons that oscillated in the Tremor-Frequency Band (TFB), ß-Frequency Band (ßFB), and the non-oscillatory cells in the MA group were 43, 115, and 62 versus 78, 68, and 54 in the LA group, respectively. The proportions of the three types of neurons were different between both groups. The firing rate of the STN neurons and the UPDRS III sub-scores were positively correlated. Additionally, we observed a positive correlation between the percentage of ßFB oscillatory neurons and bradykinesia score. CONCLUSION: The firing rate of the STN in the MA hemisphere is higher than in the LA side, following disease progression and there seems to be an increase in firing rate. The ßFB oscillatory neurons are at a larger proportion in the MA group while there were larger percentage of TFB oscillatory cells in the LA group. The proportion of ßFB oscillatory neurons is selectively correlated with the severity of bradykinesia.
