The effects of weight management on heart failure: A systematic review and meta‐analysis of randomized controlled trials

Abstract

Background

Weight management is an important part of disease management in patients with heart failure. However, the effectiveness of reported weight management interventions is inconclusive.

Aims

The aim of this systematic review and meta-analysis was to assess the effects of weight management on functional status, heart failure-related hospitalizations, and all-cause mortality in patients with heart failure.

Methods

PubMed, Web of Science, Embase, and the Cochrane Library were searched on April 3, 2022. This study was registered with PROSPERO (CRD42021283817). Eligible studies assessed functional status, heart failure-related hospitalizations, and all-cause mortality in patients with heart failure. Two researchers independently screened the articles, extracted data, and evaluated the risk bias of each study. Dichotomous variables were presented as OR with a 95% confidence interval (CI). The data were analyzed using a fixed effect or random effect model, and heterogeneity was determined using I 2 statistics. All statistical analyses were conducted using RevMan 5.3.

Results

Among 4279 studies screened, seven randomized controlled trials were included in this study. The results showed that weight management significantly improved functional status (OR = 0.15, 95% CI [0.07, 0.35], I 2 = 52%) and reduced the risk of all-cause mortality (OR = 0.54, 95% CI [0.34, 0.85], I 2 = 0%), but had no significant effect on heart failure-related hospitalizations (OR = 0.72, 95% CI [0.20, 2.66]).

Linking Evidence to Action

Weight management has effects on improved functional status and reduced all-cause mortality in patients with heart failure. It is necessary to strengthen the weight management interventions of patients with heart failure to improve patients' functional status and reduce all-cause mortality.

Nurses' preparedness, opinions, barriers, and facilitators in responding to intimate partner violence: A mixed‐methods study

Abstract

Introduction

Intimate partner violence (IPV) is associated with multiple adverse health consequences. Nurses (including midwives) are well positioned to identify patients subjected to IPV, and provide care, support, and referrals. However, studies about nursing response to IPV are limited especially in low- and middle-income countries (LMICs). The study aimed to examine nurses' perceived preparedness and opinions toward IPV and to identify barriers and facilitators in responding to IPV.

Design

An explanatory sequential mixed-methods study was conducted by collecting quantitative data first and explaining the quantitative findings with qualitative data.

Methods

The study was conducted in two tertiary general hospitals in northeastern (Shenyang city) and southwestern (Chengdu city) China with 1500 and 1800 beds, respectively. A total of 1071 survey respondents (1039 female [97.0%]) and 43 interview participants (34 female [79.1%]) were included in the study. An online survey was administered from September 3 to 23, 2020, using two validated scales from the Physician Readiness to Manage Intimate Partner Violence Survey. In-depth, semistructured interviews were conducted from September 15 to December 23, 2020, guided by the Consolidated Framework for Implementation Research.

Results

The survey respondents largely agreed with feeling prepared to manage IPV, e.g., respond to discourses (544 [50.8%] of 1071) and report to police (704 [65.7%] of 1071). The findings of surveyed opinions (i.e., Response competencies; Routine practice; Actual activities; Professionals; Victims; Alcohol/drugs) were mixed and intertwined with social desirability bias. The quantitative and qualitative data were consistent, contradicted, and supplemented. Key qualitative findings were revealed that may explain the quantitative results, including lack of actual preparedness, absence of IPV-related education, training, or practice, and socially desirable responses (especially those pertaining to China's Anti-domestic Violence Law). Commonly reported barriers (e.g., patients' reluctance to disclose; time constraints) and facilitators (e.g., patients' strong need for help; female nurses' gender advantage), as well as previously unreported barriers (e.g., IPV may become a workplace taboo if there are healthcare professionals known as victims/perpetrators of IPV) and facilitators (e.g., nurses' responses can largely meet the first-line support requirements even without formal education or training on IPV) were identified.

Conclusions

Nurses may play a unique and important role in responding to IPV in LMICs where recognition is limited, education and training are absent, policies are lacking, and resources are scarce. Our findings support World Health Organization recommendations for selective screening.

Clinical Relevance

The study highlights the great potential of nurses for IPV prevention and intervention especially in LMICs. The identified barriers and facilitators are important evidence for developing multifaceted interventions to address IPV in the health sector.

Effect of local oxygen therapy combined with vacuum sealing drainage on the healing of stage IV sacrococcygeal pressure ulcers

Abstract

The present study aimed to investigate the effect of local oxygen therapy combined with vacuum sealing drainage (VSD) on the healing of stage IV pressure ulcers sacrococcygeal. In this prospective study, we included a total of 98 patients with stage IV sacrococcygeal pressure ulcers in our hospital between February 2021 and June 2022. The patients enrolled were randomly and equally divided into two groups: the study group (undergoing local oxygen therapy combined with VSD treatment) and the control group (receiving conventional treatment). The wound healing time and hospital stay were compared between the two groups. Additionally, the wound area, tissue type, wound exudation and pain intensity were assessed before treatment, 10, 20, 30 and 40 days after treatment. The incidence of complications was also calculated. The study group demonstrated significantly shorter wound healing time and hospital stays compared to the control group (p < 0.05). Before treatment, there were no significant differences in terms of wound area, tissue type and wound exudation between the two groups (p > 0.05); after 10, 20, 30 and 40 days of treatment, however, evidently smaller wound areas, improved tissue types and reduced wound exudation were observed in the study group compared to the control group (p < 0.05). Furthermore, the study group exhibited increased microvascular count compared to the control group (p < 0.05). Before treatment, there was no significant difference in pain intensity between the two groups (p > 0.05), whereas markedly lower pain intensity was seen in the study group than in the control group after 10, 20, 30 and 40 days of treatment (p < 0.05). The incidence of complications did not significantly differ between the two groups after 40 days of treatment (p > 0.05). Local oxygen therapy combined with VSD was found to effectively accelerate the healing process of stage IV sacrococcygeal pressure ulcers, leading to shorter hospital stays and improved patient prognosis. This combined therapy shows promise for widespread application in clinical practice.

Effect of thoracoscopic and thoracotomy on postoperative wound complications in patients with lung cancer: A meta‐analysis

Abstract

Because of the difficult surgical procedures, patients with lung cancer who have received thoracic surgery tend to have postoperative complications. It may lead to postoperative complications like wound infection, wound haematoma and pneumothorax. A lot of research has assessed the effect of various surgery methods on postoperative complications in pulmonary cancer. The purpose of this meta-analysis is to establish if thoracoscopic is superior to that of thoracotomy in the rate of post-operative complications. From the beginning to the end of June 2023, we performed an exhaustive search on four main databases for key words. The Hazard of Bias in Non-Randomized Interventional Studies (ROBINS-I) was evaluated in the literature. In the end, 13 trials that fulfilled the eligibility criteria underwent further statistical analyses. The results showed that thoracoscopic intervention decreased the risk of post operative wound infection (dominant ratio [OR], 3.00; 95% confidence margin [CI], 1.98, 4.55; p < 0.00001) and air-leakage after operation (OR, 1.30; 95% CI, 1.04, 1.63; p = 0.02). There was no statistically significant difference between the two groups in terms of the rate of haemorrhage after operation (OR, 0.10; 95% CI, 0.73, 1.66; p = 0.63). Our findings indicate that thoracoscopic is less likely to cause post operative infection and gas leakage than thoracotomy, and it does not decrease the risk of postoperative haemorrhage. As some of the chosen trials are too small to conduct meta-analyses, care must be taken when handling the data. In the future, a large number of randomized, controlled trials will be required to provide additional evidence for this research.

Abstract

To summarise research studies on scar laser therapy since the 21st century using bibliometric methods, and to speculate on the possible development in the future. The literature about scar laser therapy in Web of Science database was searched. CiteSpace and VOSviewer were used to analyse main countries, institutions, journals,subject hotspots and trends, etc. A total of 884 papers have been published since the 21st century. These publications were written by 653 authors from 515 institutions in 58 countries. The United States published 287 papers in this field and ranks first. Laser in Surgery and Medicine is the most widely published journal, with Shumaker as the core author. The main keyword clustering includes terms such as combination therapy, wound healing, fractional photothermolysis, experience, scar formation, etc. CiteSpace and VOSviewer were used to sort out and summarise the countries, institutions, authors, journals, research hotspots and frontier topics of related literature about scar laser therapy since the 21st century. The current situation of its application and basic scientific research in clinical treatments were summarised briefly. This provides a new idea for the development and research of scar laser therapy in the future.

Comparison of the incidence of wound complications with preoperative and postoperative radiotherapy in patients with extremity soft tissue sarcoma resection: A meta‐analysis

Abstract

We performed a meta-analysis to compare the effect of preoperative and postoperative radiotherapy on wound complications after resection of extremity soft tissue sarcoma (ESTS). A comprehensive computerised search of the PubMed, Cochrane Library, Web of Science, EMBASE, China National Knowledge Infrastructure (CNKI), VIP, and Wanfang databases was conducted from their inception to August 2023 to identify studies comparing the effect of preoperative and postoperative radiotherapy on wound complications after ESTS resection. Two investigators independently screened the literature, extracted the data, and assessed the quality of the articles. The meta-analysis was performed using RevMan 5.4 software. Nine studies with 1271 patients were included, with 631 and 640 patients in the preoperative and postoperative radiotherapy groups, respectively. The results showed that the incidence of postoperative wound complications after ESTS resection was significantly higher with preoperative radiotherapy than with postoperative radiotherapy (27.26% vs. 12.03%, odds ratio [OR]: 2.88, 95% confidence interval [CI]: 2.12–3.91, p < 0.001). However, the rate of local recurrence of ESTS was significantly lower with preoperative radiotherapy than with postoperative radiotherapy (8.75% vs. 14.81%, OR: 0.57, 95% CI: 0.36–0.91, p = 0.02), and the 3-year overall survival was significantly higher in the preoperative radiotherapy group than in the postoperative radiotherapy group (82.24% vs. 70.04%, OR: 1.97, 95% CI: 1.05–3.71, p = 0.03). This pooled analysis suggests that although preoperative radiotherapy increases the rate of wound complications in ESTS compared with postoperative radiotherapy, it significantly reduces the rate of local recurrence after ESTS resection and improves the overall survival of patients. Owing to the limitations in the number and quality of the included studies, additional prospective cohort studies or randomised controlled trials are required to confirm these findings.

Serial mediation roles of empowerment and self‐care activities connecting health literacy, quality of life, and glycemic control in people with type 2 diabetes

Abstract

Background

Health literacy, empowerment, and self-care activities are likely the crucial concepts affecting the quality of life and glycemic control in people with type 2 diabetes (T2D). However, evidence demonstrating the mechanisms underlying these concepts is scarce.

Aims

The aim of this study was to test the serial mediation roles of empowerment and self-care activities on the relationships between health literacy and quality of life and between health literacy and hemoglobin A1c (HbA1c) in people with T2D.

Methods

A cross-sectional study was conducted among 319 people with T2D in Guangzhou, China, from July 2019 to January 2020. Data were collected using the Health Literacy Scale, the Diabetes Empowerment Scale—Short Form, the Summary of Diabetes Self-Care Activities Measure, and the Adjusted Diabetes—Specific Quality of Life Scale. RStudio 4.2.1 was used for serial mediation analysis.

Results

The dimension of communicative health literacy accounted for the most total variance (β = 0.810, p < .001) in the construct of health literacy. The serial multiple mediation of empowerment and self-care activities in the associations between health literacy and quality of life (β = −.046, p = .019) and between health literacy and HbA1c (β = −.045, p = .005) were statistically significant.

Linking evidence to action

This study emphasized the vital role of communicative health literacy when improving health literacy in people with T2D. Diabetes care and education specialists could implement empowerment approaches and flexible self-care strategies to improve the quality of life and glycemic control in people with T2D. Enhancing health literacy was suggested as a favorable strategy for promoting empowerment and self-care activities in people with T2D.

Effects of laparoscopic splenectomy on surgical site wound infection in patients with spleen rupture: A meta‐analysis

Abstract

A meta-analysis was performed to compare the effects of laparoscopic splenectomy (LS) and open splenectomy (OS) for splenic rupture on postoperative surgical site wound infections and postoperative complications. A comprehensive computerised search was conducted for studies comparing LS with OS for the treatment of splenic rupture in the PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP, and Wanfang databases, with the search including studies published in any language between the creation of the databases and August 2023. Two researchers independently screened the literature and extracted the data. Literature quality was assessed using the Newcastle-Ottawa Scale, and the included data were collated and analysed using Stata 17.0 software for meta-analysis. Twenty-two studies involving 1545 patients were included. LS was superior to OS in the following aspects: reduced risk of postoperative surgical site wound infection (OR = 0.19, 95% CI: 0.11–0.34, p = 0.000), shortened hospital stay (standardised mean difference = −1.73, 95% CI: −2.05 to −1.40, p = 0.000), and reduced postoperative complication rate (OR = 0.22, 95% CI: 0.16–0.31, p = 0.000). Compared with OS, LS has a lower rate of postoperative wound infection, shorter hospital stay, and reduced rate of postoperative complications. LS is safe and effective for the treatment of splenic rupture and can be promoted clinically.

Identification of potential immunologic resilience in the healing process of diabetic foot ulcers

Abstract

Diabetic foot ulcers (DFUs) are one of the most common and challenging complications of diabetes, yet our understanding of their pathogenesis remains limited. We collected gene expression data of DFU patients from public databases. Bioinformatics tools were applied for systematic analysis, including the identification of differentially expressed genes (DEGs), weighted gene co-expression network analysis (WGCNA) and enrichment analysis. We further used single-cell RNA sequencing to identify the distribution of different cell populations in DFU. Finally, key results were validated using reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and flow cytometry. We identified 217 DEGs between ulcerated and healthy skin, and 37 DEGs between healing ulcers and ulcers. WGCNA revealed that the cyan module had the highest positive correlation with healthy skin and negative correlation with ulcers. The black module had the highest negative correlation with healthy skin and positive correlation with ulcers. Enrichment analysis showed that the genes in the cyan module were mainly associated with complement and coagulation cascades, while the genes in the black module were mainly associated with the IL-17 signalling pathway. In addition, CD8 T cells were significantly lower in ulcers than in healthy and healing ulcers. By comparing marker genes of CD8 T cells, we identified key genes in the cyan and black modules and validated their expression using RT-qPCR. The proportion of CD8 T cells was increased in healing ulcers. Flow cytometry detected increased levels of CD8 T, B and natural killer cells in healing ulcers. CD8 T cells and related key genes play an important role in the healing process of DFU. The results of this study provide a new perspective for understanding the pathogenesis and treatment of DFU.

Design and rationale of the ATTRACTIVE trial: a randomised trial of intrAThrombus Thrombolysis versus aspiRAtion thrombeCTomy during prImary percutaneous coronary interVEntion in ST-segment elevation myocardial infarction patients with high thrombus burde

Por: Zhang · Z. · Sheng · Z. · Che · W. · An · S. · Sun · D. · Zhai · Z. · Zhao · X. · Yang · Y. · Meng · Z. · Ye · Z. · Xie · E. · Li · P. · Yu · C. · Gao · Y. · Xiao · Z. · Wu · Y. · Dong · F. · Ren · J. · Zheng · J.
Introduction

ST-segment elevation myocardial infarction (STEMI) with high thrombus burden is associated with a poor prognosis. Manual aspiration thrombectomy reduces coronary vessel distal embolisation, improves microvascular perfusion and reduces cardiovascular deaths, but it promotes more strokes and transient ischaemic attacks in the subgroup with high thrombus burden. Intrathrombus thrombolysis (ie, the local delivery of thrombolytics into the coronary thrombus) is a recently proposed treatment approach that theoretically reduces thrombus volume and the risk of microvascular dysfunction. However, the safety and efficacy of intrathrombus thrombolysis lack sufficient clinical evidence.

Methods and analysis

The intrAThrombus Thrombolysis versus aspiRAtion thrombeCTomy during prImary percutaneous coronary interVEntion trial is a multicentre, prospective, open-label, randomised controlled trial with the blinded assessment of outcomes. A total of 2500 STEMI patients with high thrombus burden who undergo primary percutaneous coronary intervention will be randomised 1:1 to intrathrombus thrombolysis with a pierced balloon or upfront routine manual aspiration thrombectomy. The primary outcome will be the composite of cardiovascular death, recurrent myocardial infarction, cardiogenic shock, heart failure readmission, stent thrombosis and target-vessel revascularisation up to 180 days.

Ethics and dissemination

The trial was approved by Ethics Committees of China-Japan Friendship Hospital (2022-KY-013) and all other participating study centres. The results of this trial will be published in peer-reviewed journals.

Trial registration number

NCT05554588.

Determinants of practice for providing decision coaching to facilitate informed values-based decision-making: protocol for a mixed-methods systematic review

Por: Berger-Höger · B. · Lewis · K. B. · Cherry · K. · Finderup · J. · Gunderson · J. · Kaden · J. · Kienlin · S. · Rahn · A. C. · Sikora · L. · Stacey · D. · Steckelberg · A. · Zhao · J.
Introduction

Decision coaching is a non-directive approach to support patients to prepare for making health decisions. It is used to facilitate patients’ involvement in informed values-based decision-making and use of evidence-based health information. A recent systematic review revealed low certainty evidence for its effectiveness with and without evidence-based information. However, there may be opportunities to improve the study and use of decision coaching in clinical practice by systematically investigating its determinants of practice. We aim to conduct a systematic review to identify and synthesise the determinants of practice for providing decision coaching to facilitate patient involvement in decision-making from multiple perspectives that influence its use.

Methods and analysis

We will conduct a mixed-methods systematic review guided by the Cochrane’ Handbook of Systematic Reviews. We will include studies reporting determinants of practice influencing decision coaching with or without evidence-based patient information with adults making a health decision for themselves or a family member. Systematic literature searches will be conducted in Medline, EMBASE, Cochrane CENTRAL and PsycINFO via Ovid and CINAHL via EBSCO including quantitative, qualitative and mixed-methods study designs. Additionally, experts in the field will be contacted.

Two reviewers will independently screen and extract data. We will synthesise determinants using deductive and inductive qualitative content analysis and a coding frame developed specifically for this review based on a taxonomy of barriers and enablers of shared decision-making mapped onto the major domains of the Consolidated Framework for Implementation Research. We will assess the quality of included studies using the Mixed Methods Appraisal Tool.

Ethics and dissemination

Ethical approval is not required as this systematic review involves only previously published literature. The results will be published in a peer-reviewed journal, presented at scientific conferences and disseminated to relevant consumer groups.

Introduction

Despite significant advances in managing acute stroke and reducing stroke mortality, preventing complications like post-stroke epilepsy (PSE) has seen limited progress. PSE research has been scattered worldwide with varying methodologies and data reporting. To address this, we established the International Post-stroke Epilepsy Research Consortium (IPSERC) to integrate global PSE research efforts. This protocol outlines an individual patient data meta-analysis (IPD-MA) to determine outcomes in patients with post-stroke seizures (PSS) and develop/validate PSE prediction models, comparing them with existing models. This protocol informs about creating the International Post-stroke Epilepsy Research Repository (IPSERR) to support future collaborative research.

Methods and analysis

We utilised a comprehensive search strategy and searched MEDLINE, Embase, PsycInfo, Cochrane, and Web of Science databases until 30 January 2023. We extracted observational studies of stroke patients aged ≥18 years, presenting early or late PSS with data on patient outcome measures, and conducted the risk of bias assessment. We did not apply any restriction based on the date or language of publication. We will invite these study authors and the IPSERC collaborators to contribute IPD to IPSERR. We will review the IPD lodged within IPSERR to identify patients who developed epileptic seizures and those who did not. We will merge the IPD files of individual data and standardise the variables where possible for consistency. We will conduct an IPD-MA to estimate the prognostic value of clinical characteristics in predicting PSE.

Ethics and dissemination

Ethics approval is not required for this study. The results will be published in peer-reviewed journals. This study will contribute to IPSERR, which will be available to researchers for future PSE research projects. It will also serve as a platform to anchor future clinical trials.

Utilizing the visual analogue scale (VAS) to monitor and manage pain in post‐operative skin wounds after thoracic surgery

Abstract

Due to the global increase in thoracic interventions, there is greater emphasis on refining post-operative care. The purpose of this study was to validate the visual analogue scale (VAS) as the valid method for measuring post-operative pain in thoracic surgery patients. From January 2020 to June 2022, this cross-sectional study investigated 240 adult patients who underwent elective thoracic surgeries in Thoracic Surgery Department of Heilongjiang Provincial Hospital. The participants were instructed to rate their discomfort using VAS at predetermined intervals after surgery. The following demographic and clinical information was recorded: age, gender, type of thoracic surgery, and history of chronic pain. Results showed a progressive decline in post-operative VAS scores over 72 h: 8.2 immediately after surgery, 6.0 at 24 h, 5.4 at 48 h, and 3.6 by 72 h. There were notable correlations between VAS scores and chronic pain history, with moderately positive correlation of 0.40 being observed. Mean scores for males and females were 3.8 and 3.9, respectively. The analysis by age revealed comparable mean scores for age categories below and above 40. With the exception of thoracic wall resection, which resulted in an average VAS score of 4.1 ± 1.0 (p < 0.05), the type of surgery had the minimal effect on variability of pain scores. The VAS is a reliable method for evaluating post-thoracic surgery discomfort. Given the substantial impact of pain history on VAS scores, there is an urgent need for personalized pain management strategies to improve post-operative care.

Attentive immobility: Investigating the emotional-cognitive mechanism underlying conspiracy mentality and Covid-19 preventive behaviors

by Shuguang Zhao, Jue Zhou, Ting Wang

While conspiracy theories have received extensive attention in the realm of misinformation, there has been limited research exploring the impact of conspiracy mentality on individuals’ preventive behaviors during acute public health crises. This study investigates how conspiracy mentality may affect compliance with preventive health measures necessary to fight the COVID-19 pandemic, and the underlying emotional and cognitive mediators. Data was collected through a survey among 1878 Chinese respondents at the conclusion of the pandemic. The results indicate that individuals with higher levels of conspiracy mentality are significantly less engaged in preventive behaviors. Furthermore, this correlation is mediated by a sequence of mediating factors, starting from anger leading to institutional distrust and fear leading to perceived risk. Conspiracists’ response mode can be described as a state of "attentive immobility," in which the impact of heightened institutional distrust outweighs their perceptions of risk, ultimately reducing engagement in preventive behaviors during crises. These findings underscore the importance of debunking initiatives that aim to address and mitigate the negative consequences of conspiracy mentality by targeting the mediating psychological processes during future pandemic threats.

Emissions reduction strategy in a three-stage agrifood value chain: A dynamic differential game approach

by Huanhuan Wang, Xiaoli Fan, Qilan Zhao, Pengfei Cui

Agrifood systems account for 31% of global greenhouse gas emissions. Substantial emissions reduction in agrifood systems is critical to achieving the temperature goal set by the Paris Agreement. A key challenge in reducing GHG emissions in the agrifood value chain is the imbalanced allocation of benefits and costs associated with emissions reduction among agrifood value chain participants. However, only a few studies have examined agrifood emissions reduction from a value chain perspective, especially using dynamic methods to investigate participants’ long-term emissions reduction strategies. This paper helps fill this gap in the existing literature by examining the impact of collaborations among agrifood value chain participants on correcting those misallocations and reducing emissions in agrifood systems. We develop a dynamic differential game model to examine participants’ long-term emissions reduction strategies in a three-stage agrifood value chain. We use the Hamilton-Jacobi-Bellman equation to derive the Nash equilibrium emissions reduction strategies under non-cooperative, cost-sharing, and cooperative mechanisms. We then conduct numerical analysis and sensitivity analysis to validate our model. Our results show that collaboration among value chain participants leads to higher emissions reduction efforts and profits for the entire value chain. Specifically, based on our numerical results, the cooperative mechanism results in the greatest emissions reduction effort by the three participants, which leads to a total that is nearly three times higher than that of the non-cooperative mechanism and close to two times higher than the cost-sharing mechanism. The cooperative mechanism also recorded the highest profits for the entire value chain, surpassing the non-cooperative and cost-sharing mechanisms by around 37% and 16%, respectively. Our results provide valuable insights for policymakers and agrifood industry stakeholders to develop strategies and policies encouraging emissions reduction collaborations in the agrifood value chain and reduce emissions in the agrifood systems.

Data glove-based gesture recognition using CNN-BiLSTM model with attention mechanism

by Jiawei Wu, Peng Ren, Boming Song, Ran Zhang, Chen Zhao, Xiao Zhang

As a novel form of human machine interaction (HMI), hand gesture recognition (HGR) has garnered extensive attention and research. The majority of HGR studies are based on visual systems, inevitably encountering challenges such as depth and occlusion. On the contrary, data gloves can facilitate data collection with minimal interference in complex environments, thus becoming a research focus in fields such as medical simulation and virtual reality. To explore the application of data gloves in dynamic gesture recognition, this paper proposes a data glove-based dynamic gesture recognition model called the Attention-based CNN-BiLSTM Network (A-CBLN). In A-CBLN, the convolutional neural network (CNN) is employed to capture local features, while the bidirectional long short-term memory (BiLSTM) is used to extract contextual temporal features of gesture data. By utilizing attention mechanisms to allocate weights to gesture features, the model enhances its understanding of different gesture meanings, thereby improving recognition accuracy. We selected seven dynamic gestures as research targets and recruited 32 subjects for participation. Experimental results demonstrate that A-CBLN effectively addresses the challenge of dynamic gesture recognition, outperforming existing models and achieving optimal gesture recognition performance, with the accuracy of 95.05% and precision of 95.43% on the test dataset.

Postoperative stellate ganglion block to reduce myocardial injury after laparoscopic radical resection for colorectal cancer: protocol for a randomised trial

Por: Hu · Z. · Li · W. · Zhao · G. · Liang · C. · Li · K.
Introduction

Stellate ganglion block (SGB) is usually used in the department of algiatry. But preoperative SGB may reduce adverse cardiovascular events in high-risk patients, although evidence remains sparse. Therefore, we aim to determine whether a single-shot postoperative SGB can reduce the incidence of myocardial injury after non-cardiac surgery (MINS) and improve recovery in patients undergoing laparoscopic radical resection for colorectal cancer.

Methods and analysis

This is an investigator-initiated, single-centre, randomised, two-arm clinical trial enrolling patients aged over 45 years and scheduled for elective laparoscopic radical colorectal surgery with at least one risk factor for MINS. A total of 950 eligible patients will be randomised into a routine or block groups. The primary outcome is the incidence of MINS. The secondary outcomes include the Visual Analogue Scale of pain during rest and movement, the incidence of delirium, quality of recovery (QOR) assessed by QOR-15, and sleep quality assessed by Richards Campbell Sleep Questionnaire. Tertiary outcomes include time to first flatus, gastrointestinal complications such as anastomotic leak or ileus, length of hospital stay, collapse incidence of severe cardiovascular and cerebrovascular complications of myocardial infarction, cardiac arrest, ischaemic or haemorrhagic stroke, and all-cause mortality within 30 days after the operation.

Ethics and dissemination

The protocol was approved by Medical Ethics Committee of the China-Japan Union Hospital, Jilin University (Approval number: 2021081018) prior to recruitment. The study will be performed according to the guidelines of the Declaration of Helsinki. The findings of this study will be published and presented through various scientific forums.

Three rural areas of Yunnan, China.

Participants

We invited 8187 consenting participants in 2010–2011 and 7572 consenting participants in 2020–2021 to undergo interviews and health examinations.

Results

The standardised prevalence of hypertension significantly increased from 26.1% in 2011 to 40.4% in 2021 (p

Conclusions

The prevalence and economic burden of hypertension have visibly accelerated in rural Yunnan Province over the 10 years studied, and socioeconomic disparities have been found in the prevalence and economic burden of hypertension. These findings highlight that socioeconomic differentials should be tailored to address the timing of effective interventions for hypertension prevention and control and reduce the economic burden of hypertension in rural southwestern China.

Influencing factors and improvement paths of manufacturing innovation performance: Configuration analysis based on TOE framework

by Youcai Ma, Zhaobing Cui

Innovation is the first driving force to lead development, how to improve manufacturing innovation performance has become a hot topic. Based on 47 listed companies in the computer, communication and other electronic equipment manufacturing industry in the A-share market, this paper adopted the Fuzzy set qualitative comparative analysis (fsQCA) to explore the influencing factors of technology, organization and environment on the innovation performance of manufacturing industry and the improvement path. The findings are as follows: (1) A single condition is not a necessary condition for high innovation performance in manufacturing industry, but government support plays a key role in improving innovation performance in manufacturing industry. (2) There are two improvement paths for high innovation performance in manufacturing industry, which are specifically explained as “technology-environment dual improvement path” and “technology-organization-environment collaborative improvement path”. (3) The improvement of innovation performance in the manufacturing industry is the result of multiple factors, showing the characteristics of “all paths lead to the same destination”. Different manufacturing enterprises have different paths to improve innovation performance based on their actual conditions. Based on these findings, this study may provide some implications for the effective improvement of manufacturing innovation performance.
