Antimicrobial resistance is a major threat to human health globally. Antrodia camphorata was grown in a malt/yeast extract broth liquid medium for 15 days. Then, 4-L fermentation broth was harvested, yielding 7.13 g of the ethyl acetate extract. By tracing the antimicrobial activity, 12.22 mg of the antimicrobial compound was isolated. The structure of 5-methyl-benzo [1,3]-dioxole-4,7-diol (MBBD) was elucidated using NMR and MS data analyses. The antibacterial activity of MBBD was detected through the microbroth dilution method. MBBD exhibited broad-spectrum antibacterial activity. The minimum inhibitory concentration (MIC) range of MBBD for drug-resistant pathogenic bacteria was 64–256 μg/mL, with the lowest MIC observed for Acinetobacter baumannii (64 μg/mL), followed by Pseudomonas aeruginosa (MIC = 128 μg/mL). Klebsiella pneumoniae, Staphylococcus aureus, Enterococcus faecalis, and Escherichia coli were also sensitive, with an MIC of 256 μg/mL. The MIC range of MBBD against 10 foodborne pathogens was 12.5–100 μg/mL. Based on the results of this study, MBBD exhibits broad-spectrum antibacterial activity, particularly demonstrating excellent inhibitory effects against A. baumannii. MBBD will be good candidates for new antimicrobial drugs.

Mytilus coruscus is an economically important marine bivalve mollusk found in the Yangtze River estuary, which experiences dramatic pH fluctuations due to seasonal freshwater input and suffer from shell fracture or injury in the natural environment. In this study, we used intact-shell and damaged-shell M. coruscus and performed metabolomic analysis, free amino acids analysis, calcium-positive staining, and intracellular calcium level tests in the mantle to investigate whether the mantle-specific metabolites can be induced by acute sea-water acidification and understand how the mantle responds to acute acidification during the shell repair process. We observed that both shell damage and acute acidification induced alterations in phospholipids, amino acids, nucleotides, organic acids, benzenoids, and their analogs and derivatives. Glycylproline, spicamycin, and 2-aminoheptanoic acid (2-AHA) are explicitly induced by shell damage. Betaine, aspartate, and oxidized glutathione are specifically induced by acute acidification. Our results show different metabolic patterns in the mussel mantle in response to different stressors, which can help elucidate the shell repair process under ocean acidification. furthermore, metabolic processes related to energy supply, cell function, signal transduction, and amino acid synthesis are disturbed by shell damage and/or acute acidification, indicating that both shell damage and acute acidification increased energy consumption, and disturb phospholipid synthesis, osmotic regulation, and redox balance. Free amino acid analysis and enzymatic activity assays partially confirmed our findings, highlighting the adaptation of M. coruscus to dramatic pH fluctuations in the Yangtze River estuary.

‘There is always good fortune in misfortune to encourage us in coping with difficulties’—The lived experiences of family caregivers of people with dementia during the COVID‐19 outbreak in China: A phenomenological study

Por: Qiongqiong Zhang · Bin Li · Jing Han · Sanmei Chen · Yongchao Lu · Shengnan Tang · Qingyan Wang — Octubre 5th 2023 at 07:41

Abstract

Aim

To describe the lived experiences of family caregivers of individuals with dementia during the coronavirus disease (COVID-19) outbreak in China.

Design

This study used a descriptive phenomenological research method.

Methods

Between May and September 2021, semi-structured interviews were conducted with 22 family caregivers of people with dementia. Colaizzi's method was used for manual analysis.

Results

Qualitative data revealed an overarching experience of finding ‘There is always good fortune in misfortune to encourage us in coping with difficulties’. Three themes emerged: family reactions to the COVID-19 outbreak, feeling supported by multiple resources performing respective functions and resilient adaptation to new situations.

Conclusion

During the COVID-19 outbreak, family caregivers of people living with dementia in China looked for positive aspects among difficulties and experienced corresponding reactions, social support resources and resilient adapted coping styles.

Implications for the Profession and/or Patient Care

Nurses in China and other countries facing similar pandemic characteristics, cultures or economic development levels, can guide family caregivers to look at family hardships from a positive perspective, develop interventions to rapidly respond to families' reactions after a disaster and help them identify social support resources and form adapted coping styles.

Impact

We identified the resilience and the positive experiences of Chinese family caregivers of individuals with dementia during the COVID-19 outbreak. The results can inform countries with similar cultures and economic levels, offering measures to support their adaptation to pandemics.

Reporting Method

This study followed the COREQ guidelines.

Patient or Public Contribution

Family caregivers of people with dementia who met the inclusion criteria and who were interested in sharing their understanding of their experiences, participated in the study.

Short‐term professional bereavement reactions and their links with the meaning of patient death: Evidence from network analyses

Por: Chuqian Chen · Robert Jiqi Zhang — Octubre 9th 2023 at 08:29

Abstract

Objectives

Taking a dimensional view, this study aims to understand, among professional caregivers after patient deaths, the symptom distribution and development of the short-term bereavement reaction (SBR) network and the node-level links between the meaning of patient death (MPD) and the SBR network.

Methods

A cross-sectional secondary analysis was conducted with existing data from 220 Chinese urban hospital nurses and physicians who experienced the most recent patient death within a month. MPD was measured by the 10 formative items of the meaning of patient death model, and SBR was measured by the Short-term Bereavement Reactions Subscale of the Professional Bereavement Scale. Both Gaussian graphical network analysis and Bayesian network analysis were applied to the SBR network, and Gaussian graphical network analysis was used to estimate the MPD-SBR network.

Results

Frustrated and guilty are central nodes in the regularized partial correlation SBR network. Meanwhile, a traumatic event and failure at work are important bridge nodes between the MPD network and the SBR network. In the Bayesian SBR network, moved by the family's understanding, moved by the family's gratitude and sad mainly drive other nodes.

Conclusion

After a patient death, nurses' and physicians' SBR networks feature professional-dimension symptoms at their core, while they follow ‘personal to professional’ and ‘concrete to abstract’ symptom development patterns. The personal meaning of a traumatic event and the professional meaning of a failure at work play key roles in bridging the MPD and SBR networks, and meanings of both the personal and the professional dimensions can link to professional-dimension reactions.

Reporting Method

The manuscript followed the STROBE checklist for reporting cross-sectional studies.

The cognitive appraisal path of stroke knowledge, coping traits, family functioning and stigma among stroke patients: A moderated parallel mediation model

Por: Heng‐Yu Liu · Qun‐Hong Liu · Zhuo‐Ran Li · Cheng‐Song Deng · Xiao‐Pei Zhang · Li‐Hong Wan — Octubre 13th 2023 at 08:05

Abstract

Aims

To establish a cognitive appraisal path model that examines the impact of stroke knowledge on stigma with the parallel mediating effects of negative and positive coping traits, as well as the moderating effects of family functioning.

Background

Stroke-related stigma, a ‘mixture’ of negative emotions involving internal criticism and external judgement, has been shown to impair patients' health outcomes. However, the specific factors underlying cognitive appraisals and their pathways remain unknown.

Design

A cross-sectional design.

Methods

The cross-sectional sample was from two stroke centres in China. Questionnaires were administered to collect sociodemographic data, stroke knowledge, coping traits, family functioning and stigma. Hierarchical regression models and the moderated parallel mediation model were constructed to analyse influencing pathways. The study adhered to the strengthening the reporting of observational studies in epidemiology guideline.

Results

All 144 samples reported stigma symptoms with a moderate-to-high standardising score. The best hierarchical regression model explains 55.5% of the variance in stigma. The parallel mediation model indicated that negative and positive coping traits co-mediating the association of stroke knowledge and stigma. After adding the family functioning as a moderator, the moderated parallel mediation model was confirmed with adequate fit indices.

Conclusion

Among the cognitive appraisal factors affecting stroke-related stigma, stroke knowledge reduces stigma by modifying coping traits, while poor family functioning may serve as an opposing moderator. Notably, when family support is insufficient, enhanced stroke knowledge might paradoxically exacerbate the stigma.

Relevance to Clinical Practice

This study contributes knowledge on transforming health education and emphasises the pivotal roles of clinical nursing practitioners. In similar global contexts, the study highlights integrating health education, psychological counselling and family support to advance systematic nursing practices.

Por: Yao Fu · Junbo Zhao · Wenjin Zhang · Hailiang Du · Zhiqin Cao · Xingfeng Chen — Octubre 26th 2023 at 08:15

Abstract

No Patient or Public Contribution, because the relevant data of this article comes from the literature database.

Purpose

The present study aimed to investigate the trends and research status of sexual healthcare.

Methods

We searched the Web of Science database for relevant articles concerning sexual healthcare, published between 2009 and 31 December 2022. Data collected include: the number of publications, authors, journals, countries, institutions, keywords. VOSviewer and CiteSpace were used to conduct the bibliometric study and visualise the analysis.

Results

A total of 1450 publications were included. The number of publications on sexual healthcare shows a fluctuating upward trend, and a stable core group of authors has been formed. The Journal of Clinical Nursing published the most articles on sexual healthcare (140 publications). The United States of America published the most articles (723, 49.86%). The research institution with the highest number of publications is the University of São Paulo. According to the keyword, timeline view and prominence mapping analysis, we believe that ‘Female sexual health’, ‘HIV’, ‘LGBT’ and ‘Sexual Healthcare Services’ may be new research hotspots in the field of sexual healthcare.

Conclusion

This study describes the research status of sexual healthcare research over the past 14 years. The findings of this study can provide helpful reference and guidance for the development trend and research direction of sexual healthcare.

A behavioural driving model of adherence to home‐based cardiac rehabilitation exercise among patients with chronic heart failure: A mixed‐methods study

Por: Zhen Yang · Honghong Jia · Fengpei Zhang · Hao Huang · Xinyi Hao · Aiping Wang — Octubre 26th 2023 at 08:30

Abstract

Aims and Objectives

To develop and validate a behavioural driving model for adherence to home-based cardiac rehabilitation exercise in patients with chronic heart failure, and to explain the potential driving mechanism of social support on exercise adherence.

Background

Despite the benefits of home-based cardiac rehabilitation exercise, adherence among patients with chronic heart failure remains suboptimal. Several factors contributing to adherence have been confirmed; however, the specific pathway mechanisms by which these factors impact exercise adherence have not been thoroughly explored.

Design

An exploratory sequential mixed-methods study was conducted in this study.

Methods

A total of 226 patients with chronic heart failure were recruited using convenience sampling. Quantitative data were collected using a series of self-report questionnaires. Hierarchical regression analysis was performed to verify multiple pathways. Subsequently, 12 patients with chronic heart failure were drawn from the quantitative stage. The interview data were thematically analysed. This study followed the Good Reporting of a Mixed Methods Study (GRAMMS) guidelines (Appendix S1).

Results

Perceived social support had a direct positive predictive effect on exercise adherence. Importantly, exercise self-efficacy and exercise fear played a chain-mediating role between perceived social support and exercise adherence. As a result of the qualitative phase, scale, tightness and homogeneity of social support networks emerged as potential drivers of the effectiveness of social support on exercise adherence.

Conclusions

This study reveals a potential pathway mechanism for social support to improve adherence to home-based cardiac rehabilitation exercises. Social support network plays a crucial role in the effect of social support on exercise adherence.

Relevance to Clinical Practice

To enhance exercise adherence in home-based cardiac rehabilitation for patients with chronic heart failure, establishing a social support network is recommended. This strategy has the potential to promote exercise self-efficacy and alleviate exercise fear.

Organ donation decision-making in ICU patients: from the perspectives of organ coordinators and physicians in China - a qualitative study

Por: Yang · X. · Chen · C. · Geng · K. · Jia · X. · Si · F. · Lu · X. · Zhang · W. · Du · S. · Zhang · X. · Guo · W. · Yin · Z. — Noviembre 1st 2023 at 16:42
Objectives

Intensive care unit (ICU) dying patients are the most important source of organ donation. This study explores the reasons affecting organ donation in the Chinese sociocultural context from the perspectives of coordinators and physicians, and further seeks countermeasures to alleviate the shortage of organs.

Design and setting

Semistructured interviews conducted in a large tertiary hospital in China.

Participants and method

15 respondents (including 8 organ coordinators and 7 ICU physicians) were interviewed. Participants were invited to describe the factors that influence organ donation and the underlying reasons behind it. Bronfenbrenner’s socioecological system model was used as theoretical support to construct a theoretical model of the factors influencing organ donation. Respondents participated in semistructured qualitative interviews that were audio-recorded and transcribed. The relevant data were analysed using thematic analysis.

Results

Four themes that influenced organ donation were identified including the influence of the deceased person’s attributes, immediate family members, surrounding people and the environment, and the social-level factors. In addition, we obtained four strategies from the interviews to improve the organ shortage to ameliorate the current supply–demand imbalance in organ donation. These include multilevel publicity, relevant policy support, increasing other forms of supply and reducing organ demand.

Conclusions

Factors affecting organ donation after the death of a Chinese citizen include the personal characteristics of the donor, the decisions of family members such as immediate family members and the indirect influence of surrounding people such as collateral family members, in addition to factors related to the humanistic environment, religious beliefs and social opinion.

Barriers and facilitators to dementia care in long-term care facilities: protocol for a qualitative systematic review and meta-synthesis

Por: Zhang · X. · Guan · C. · He · J. · Wang · J. — Noviembre 1st 2023 at 16:42
Introduction

Long-term care needs for people with dementia are predicted to increase due to increased life expectancy and dementia diagnoses. Most published meta- syntheses of dementia care focus on hospitals or home settings. When focusing on long-term care facilities, most reviews about dementia care only focus on a single outcome, such as feeding, behavioural symptoms management, palliative care and others, which is limited. The present study aims to synthesise qualitative data and examine barriers and facilitators to caring for people with dementia in long-term care facilities.

Methods and analysis

This is the protocol for our systematic review and meta-synthesis, which describes the design of this study, and we plan to complete the study from October 2023 to November 2024. The systematic review and meta-synthesis will follow the Joanna Briggs Institute (JBI) guidance for systematic reviews of qualitative evidence. Nine databases (five English and four Chinese) were searched, including Embase, Web of Science, Medline, CINAHL, PsycINFO and Wan Fang Data, China National Knowledge Infrastructure, VIP and Chinese Biomedical Medicine, from inception to August 2023. Qualitative and mixed-approach research about barriers and facilitators to caring for people with dementia in long-term care facilities, which are reported in English or Chinese, will be included. Covidence software will help with study selection, assessment and data extraction. The JBI Critical Appraisal Checklist for Qualitative Research (2020) will be used for included studies’ quality assessment. Data extraction will be based on the JBI Qualitative Assessment and Review Instrument Data Extraction Tool for Qualitative Research. The JBI aggregation approach will be used to synthesise data. We will use the JBI ConQual tool to assess the credibility and dependability of each synthesised finding to establish confidence in the synthesised findings. All review steps will be managed by two reviewers independently, and disparities will be discussed. If consensus cannot reach a resolution, a third reviewer will be consulted.

Ethics and dissemination

The present study is a secondary analysis of published qualitative data. So ethical approval is not required. The findings may be disseminated through peer-reviewed publications, conference papers or elsewhere.

PROSPERO registration number

The protocol was registered with the International Prospective Register of Systematic Reviews (PROSPERO) in May 2022, and the registration number is CRD42022326178.

Comparison of ultrasound-guided and traditional localisation in intraspinal anesthesia: a systematic review and network meta-analysis

Por: Zhang · Y. · Peng · M. · Wei · J. · Huang · J. · Ma · W. · Li · Y. — Noviembre 2nd 2023 at 17:14
Objectives

The optimal puncture technique for neuraxial anaesthesia in different populations is unclear. We sought to obtain data from randomised controlled trials comparing the impact of ultrasound-guided technology and traditional positioning technology on the success rate of neuraxial anaesthesia.

Design

Systematic review and network meta-analysis using study populations, interventions, intervention comparisons, outcome measures and study types.

Data sources

PubMed, Embase, Cochrane Library and Web of science were searched until 31 September 2022.

Eligibility criteria

We included randomised controlled trials comparing three types of neuraxial anaesthesia: ultrasound-assisted, ultrasound real-time guidance and conventional positioning to describe which neuraxial anaesthesia modality is best for patients and to recommend the appropriate one for different populations.

Data extraction and synthesis

Five independent reviewers retrieved, screened and edited included studies using standardised methods. Assess risk of bias using the Cochrane Collaboration and Evidence Project tools. Network meta-analysis was performed using STATA V.15 statistical software.

Results

Twenty-two studies containing three different interventions were included. The SUCRA values of first-pass success rates for the three neuraxial anaesthesia methods were real-time guidance (82.8%), ultrasound-assisted (67.1%) and traditional positioning (0.1%). Both ultrasound techniques improved first-pass success rates compared with traditional localization, but there was no significant difference between the two. Subgroup analysis showed that the use of real-time ultrasound guidance for neuraxial anaesthesia in pregnant and patients with obesity improved first-pass success rates. Ultrasound-assisted technology can improve first-attempt success rates in older patients with abnormal lumbar spine anatomy.

Conclusion

Compared with conventional positioning, ultrasound guidance technology can improve the first-pass success rate of neuraxial anaesthesia, but there is no significant difference between ultrasound-assisted and real-time guidance technology. The results of subgroup analysis tell us that the most suitable neuraxial anaesthesia method is different for different groups of people.

Barriers and facilitators of implementing the practice programme for upright positions in the second stage of labour: A mixed‐method study

Por: Jing Huang · Bei Wang · Kejuan Sun · Huixin Zhang · Fan Bai · Hangjie Lian · Chen Lei · Yifan Cheng · Ke Nie · Yu Zang — Noviembre 3rd 2023 at 11:18

Abstract

Objective

To explore the possible barriers and facilitators to implementing the Upright Positions in the Second Stage of Labour (UPSSL) programme in Chinese healthcare settings.

Design

A mixed-method convergent design with the guidance of Consolidated Framework for Implementation Research (CFIR).

Methods

An online survey study and semi-structured interviews were conducted between March and May 2023. Healthcare professionals were recruited from four hospitals in Shijiazhuang, China. One hundred and thirty-one participants completed the survey study, and 23 of them were interviewed individually. Descriptive statistics evaluated the possible barriers and facilitators of implementing the UPSSL programme within the CFIR framework quantitatively. Guided by the CFIR framework, qualitative data were analysed using directed content analysis to summarize healthcare professionals' perspectives on barriers and facilitators of the UPSSL programme.

Results

Multiple intersectional barriers and facilitators were identified from the survey and semi-interviews. Healthcare professionals believed that the UPSSL programme has a scientific evidence base, systematic contents, and possible benefits for women. However, various barriers existed at individual, system, and organizational levels. Major barriers included healthcare professionals and women's safety concerns towards the use of upright positions during childbirth, the healthcare professionals' unfamiliarity with assisting an upright position birth, poor adaptability of the programme protocol, inadequate facilities and staffing, and a lack of readiness to change in the clinical setting.

Conclusions

To facilitate the implementation of the UPSSL programme in China, tailored antenatal education on upright positions, especially addressing safety-related issues, should be provided to pregnant women, their families, or peers to enhance their understanding of and familiarity with such positions. Healthcare professionals should also be offered adequate training opportunities and necessary facilities. Furthermore, national-level policy changes might be required to address midwifery workforce shortages. Additionally, further research is warranted to select, adapt, and test effective implementation strategies for programme adoption.

Implications for the Profession and/or Patient Care

What problem did the study address? The adoption of upright positions during the second stage of labour could promote better maternal and neonatal outcomes and a positive childbirth experience. However, the adoption of upright positions during the second stage of labour is suboptimal in healthcare settings in China. Barriers and facilitators of implementing upright positions during childbirth are unclear. What were the main findings? A range of barriers and facilitators within the CFIR framework to promote upright positions during childbirth from healthcare professionals' perspectives were identified, and the major barriers included safety concerns towards and unfamiliarity with an upright position birth, inadequate facilities and staffing, and a lack of readiness to change in the clinical setting. Where and on whom will the research have an impact? This study will enable a better understanding of the barriers and facilitators to promoting upright positions in the second stage of labour in China. The smooth and effective implementation of the UPSSL programme could help to promote better maternal and neonatal outcomes and improve women's childbirth experiences.

Reporting Method

The reporting of this study followed the Consolidated Criteria for Reporting Qualitative Research (COREQ) and Good Reporting of A Mixed Methods Study (GRAMMS) guidelines.

Patient or Public Contribution

In this study, healthcare professionals were involved in refining the topic guides and survey questions. Additionally, findings from the interviews were returned to them for comments and corrections.

Predictive model for estimating the risk of high-altitude pulmonary edema: a single-centre retrospective outcome-reporting study

Por: Suona · Y. · Gesang · L. · Danzeng · Z. · Ci · B. · Zhaxi · Q. · Huang · J. · Zhang · R. — Noviembre 3rd 2023 at 15:24
Objective

To develop the first prediction model based on the common clinical symptoms of high-altitude pulmonary edema (HAPE), enabling early identification and an easy-to-execute self-risk prediction tool.

Methods

A total of 614 patients who consulted People’s Hospital of Tibet Autonomous Region between January 2014 and April 2022 were enrolled. Out of those, 508 patients (416 males and 92 females) were diagnosed with HAPE and 106 were patients without HAPE (33 females and 72 males). They were randomly distributed into training (n=431) and validation (n=182) groups. Univariate and multivariate analysis were used to screen predictors of HAPE selected from the 36 predictors; nomograms were established based on the results of multivariate analysis. The receiver operating characteristic curve (ROC) was developed to obtain the area under the ROC curve (AUC) of the predictive model, and its predictive power was further evaluated by calibrating the curve, while the Decision Curve Analysis (DCA) was developed to evaluate the clinical applicability of the model, which was visualised by nomogram.

Results

All six predictors were significantly associated with the incidence of HAPE, and two models were classified according to whether the value of SpO2 (percentage of oxygen in the blood) was available in the target population. Both could accurately predict the risk of HAPE. In the validation cohort, the AUC of model 1 was 0.934 with 95% CI (0.848 to 1.000), and model 2 had an AUC of 0.889, 95% CI (0.779 to 0.999). Calibration plots showed that the predicted and actual HAPE probabilities fitted well with internal validation, and the clinical decision curve shows intervention in the risk range of 0.01–0.98, resulting in a net benefit of nearly 99%.

Conclusion

The recommended prediction model (nomogram) could estimate the risk of HAPE with good precision, high discrimination and possible clinical applications for patients with HAPE. More importantly, it is an easy-to-execute scoring tool for individuals without medical professionals’ support.

Effect of different catheter pathways on wounds after minimally invasive radical prostatectomy: A meta‐analysis

Por: Tao Wang · Shiben Ji · Ci Zhang · Yang Xiang · Guohong Yin — Octubre 31st 2023 at 09:38

Abstract

Prostate cancer is one of the most common malignancies worldwide and the fifth leading cause of cancer deaths in men. With the rapidly increasing surgical rate of minimally invasive radical prostatectomy, there is still controversy about how to use a urinary catheter post-operatively. Thus, we attempted to compare the post-operative wound-related outcomes through a meta-analysis of urethral catheterisation (UC) versus suprapubic catheterisation (SPC) after minimally invasive radical prostatectomy. As of August 2023, the authors conducted systematic searches in databases such as PubMed, Embase, Web of Science and the Cochrane Library. The authors reviewed the relevant literature separately to determine comparisons between SPC and UC treatment after radical prostatectomy. A total of 395 subjects were enrolled in the five trials, met the eligibility criteria and were included in the meta-analysis. Data collection and analysis revealed significant differences in catheter bother to patients for surgical trauma (MD, 0.98; 95% CI, 0.48, 1.48 p = 0.0001), with SPC causing less catheter bother to patients post-operatively; post-operative catheter-related problems (OR, 3.3; 95% CI, 0.03, 326.1 p = 0.61), the POD1 of the post-operative period (MD, − 0.09; 95% CI, −0.75, 0.94 p = 0.83) and the POD3 of the post-operative period (MD, −0.49; 95% CI, −0.99, 0.01 p = 0.06); there was no statistically significant difference in wound pain. Compared with UC, SPC patients had less post-operative catheter distress. Thus, SPC is more beneficial in reducing post-operative wound discomfort in patients. The validity of the results remains to be tested in more and better studies.

The potential role of ferroptosis in the physiopathology of deep tissue injuries

Por: Lin Han · Juhong Pei · Hongxia Tao · Xiaojing Guo · Yuting Wei · Zhuang Yang · Hongyan Zhang — Octubre 31st 2023 at 11:23

Abstract

Deep tissue injuries (DTIs) are a serious type of pressure injuries that mainly occur at the bony prominences and can develop rapidly, making prevention and treatment more difficult. Although consistent research efforts have been made over the years, the cellular and molecular mechanisms contributing to the development of DTIs remain unclear. More recently, ferroptosis, a novel regulatory cell death (RCD) type, has been identified that is morphological, biochemical and genetic criteria distinct from apoptosis, autophagy and other known cell death pathways. Ferroptosis is characterized by iron overload, iron-dependent lipid peroxidation and shrunken mitochondria. We also note that some of the pathological features of DTI are known to be key features of the ferroptosis pathway. Numerous studies have confirmed that ferroptosis may be involved in chronic wounds, including DTIs. Here, we elaborate on the basic pathological features of ferroptosis. We also present the evidence that ferroptosis is involved in the pathology of DTIs and highlight a future perspective on this emerging field, desiring to provide more possibilities for the prevention and treatment of DTIs.

Risk factors for sternal wound infection after open‐heart operations: A systematic review and meta‐analysis

Por: Dongsheng Chen · Jianghe Zhang · Yuting Wang · Weiqian Jiang · Yujian Xu · Chenlu Xiong · Zekun Feng · Yan Han · Youbai Chen — Noviembre 1st 2023 at 10:48

Abstract

We aimed to quantitatively and systematically elucidate the rationality of the examined variables as independent risk factors for sternal wound infection. We searched databases to screen studies, ascertained the variables to be analysed, extracted the data and applied meta-analysis to each qualified variable. Odds ratios and mean differences were considered to be the effect sizes for binary and continuous variables, respectively. A random-effects model was used for these procedures. The source of heterogeneity was evaluated using a meta-regression. Publication bias was tested by funnel plot and Egger's test, the significant results of which were then calculated using trim and fill analysis. We used a sensitivity analysis and bubble chart to describe their robustness. After screening all variables in the eligible literature, we excluded 55 because only one or no research found them significant after multivariate analysis, leaving 33 variables for synthesis. Two binary variables (age over 65 years, NYHA class >2) and a continuous variable (preoperative stay) were not significant after the meta-analysis. The most robust independent risk factors in our study were diabetes mellitus, obesity, use of bilateral internal thoracic arteries, chronic obstructive pulmonary disease, prolonged surgery time, prolonged ventilation and critical preoperative state, followed by congestive heart failure, atrial fibrillation, renal insufficiency, stroke, peripheral vascular disease and use of an intra-aortic balloon pump. Relatively low-risk factors were emergent/urgent surgery, smoking, myocardial infarction, combined surgery and coronary artery bypass grafting. Sternal wound infection after open-heart surgery is a multifactorial disease. The detected risk factors significantly affected the wound healing process, but some were different in strength. Anything that affects wound healing and antibacterial ability, such as lack of oxygen, local haemodynamic disorders, malnutrition condition and compromised immune system will increase the risk, and this reminds us of comprehensive treatment during the perioperative period.

Effect of laparoscopic versus open surgery on postoperative wound complications in patients with low rectal cancer: A meta‐analysis

Por: Shu Yang · Yuting Lin · Wenjin Zhong · Wenji Xu · Zhongxin Huang · Suqin Cai · Wen Chen · Baogen Zhang — Noviembre 8th 2023 at 01:52

Abstract

This meta-analysis was conducted to evaluate the effect of microinvasive and open operations on postoperative wound complications in low rectal carcinoma patients. Research on limited English has been conducted systematically in PubMed, Embase, Cochrane Library and Web of Science. The date up to the search was in August 2023. Following review of the classification and exclusion criteria for this research and the evaluation of its quality in the literature, there were a total of 266 related papers, which were reviewed for inclusion in the period from 2004 to 2017. A total of 1774 cases of low rectal cancer were enrolled. Of these 913 cases, the laparoscopic operation was performed on 913 cases, while 861 cases were operated on low rectal carcinoma. The overall sample was between 10 and 482. Five trials described the efficacy of laparoscopy have lower risk than open on postoperative wound infection in patients with low rectal cancer (OR, 0.72;95 % CI, 0.48,1.09 p = 0.12). Three studies results showed that the anastomotic leak was not significantly different between open and laparoscopy (OR, 0.86; 95% CI, 0.58,1.26 p = 0.44). Six surgical trials in low rectal cancer patients reported haemorrhage, and five cases of surgical time were reported, with laparoscopy having fewer bleeding compared with open surgery (MD, −188.89; 95% CI, −341.27, −36.51 p = 0.02). Compared with laparoscopy, the operation time was shorter for the open operation (MD, 33.06; 95% CI, 30.56, 35.57 p < 0.0001). Overall, there is no significant difference between laparoscopy and open surgery in terms of incidence of infection and anastomosis leak. However, the rate of haemorrhage in laparoscopy is lower,and operation time in open surgery is lower.

Abstract

A meta-analysis was conducted to evaluate the effect of colostomy or ileostomy on post-operative wound complications. The research was tested using Embase, PubMed and Cochrane Library databases. Included were randomized, controlled clinical trials (RCTs). A sensitivity analysis and a meta-analysis were carried out. The results indicated that there were no statistically significant differences in the reduction of wound infection between LC and LI. Out of 268 related studies, 5 publications were chosen and examined for compliance. Literature quality was evaluated throughout the trial. Studies with poor literature were excluded. The data were analysed with RevMan 5.3, and a decision was taken to analyse the data with either a stochastic or a fixed-effects model. There were no significant differences in the incidence of post-operative infection in patients with LC (OR, 0.79; 95% CI, 0.34, 1.81; p = 0.57), and the incidence of post-operative anastomotic fistulae (OR, 0.98; 95% CI, 0.30, 3.15; p = 0.97) was not significantly different from that with LI. These meta-analyses indicate that no significant reduction in the incidence of post-operative infections or anastomotic fistulae was observed by either LC or LI.

Abstract

To explore the effect of rapid rehabilitation nursing model on surgical site wound infection and pain of patients with ovarian cancer. Computer searches were performed on randomised controlled trials (RCTs) of rapid rehabilitation nursing model applied to ovarian cancer patients in PubMed, Cochrane Library, Embase, China National Knowledge Infrastructure (CNKI), China Biomedical Literature Database (SinoMed), VIP and Wanfang Database from the time each database was constructed to May 2023. Two researchers independently screened the literature, extracted data and completed an assessment of the quality of the literature based on the inclusion and exclusion criteria. Meta-analysis was performed using RevMan 5.4 software. The database was searched to obtain 255 articles, and 22 articles were finally included, containing 966 patients in the experimental group and 954 patients in the control group, for a total of 1920 patients. The results of the meta-analysis showed that, compared with other nursing models, the use of the rapid rehabilitation nursing model significantly reduced surgical site wound infections in patients with ovarian cancer (OR = 0.30, 95% CI: 0.15–0.61, p < 0.001) and the rate of post-operative complications (OR = 0.27, 95% CI: 0.19–0.38, p < 0.001) also reduced the patients' post-operative wound pain (MD = −0.70, 95% CI: −0.85 to −0.55, p < 0.001). The rapid rehabilitation nursing model applied to patients with ovarian cancer surgery can effectively reduce the rate of post-operative complications and wound infections, and it can also reduce the post-operative wound pain.

Meta‐analysis on the efficacy of Traditional Chinese Medicine in enhancing surgical site wound healing post‐colorectal surgery

Por: Han‐song Liu · Haihua Qian · Jiali Liu · Dan Zhang — Noviembre 13th 2023 at 07:25

Abstract

This meta-analysis aimed to evaluate the efficacy of Traditional Chinese Medicine (TCM) in enhancing surgical site wound healing following colorectal surgery. We systematically reviewed and analysed randomized controlled trials (RCTs) that investigated the outcomes of TCM interventions in postoperative wound management, adhering to the PRISMA guidelines. The primary outcome was the assessment of wound healing through the REEDA (redness, oedema, ecchymosis, discharge and approximation) scale at two different time points: the 10th day and 1-month post-surgery. Seven RCTs involving 1884 patients were included. The meta-analysis revealed a statistically significant improvement in wound healing in the TCM-treated groups compared to the control groups at both time intervals. On the 10th day post-surgery, the TCM groups exhibited a significant reduction in REEDA scale scores (I2 = 98%; random: SMD: −2.25, 95% CI: −3.52 to −0.98, p < 0.01). A similar trend was observed 1-month post-surgery, with the TCM groups showing a substantial decrease in REEDA scale scores (I 2 = 98%; random: SMD: -3.39, 95% CI: −4.77 to −2.01, p < 0.01). Despite the promising results, the majority of the included studies were of suboptimal quality, indicating a need for further high-quality RCTs to substantiate the findings. The results suggest that TCM interventions can potentially enhance wound healing post-colorectal surgery, paving the way for further research in this area to validate the efficacy of TCM in postoperative management.

The home language environment is a critical point of investment in early language skills. However, few studies have quantitatively measured the home language environment of low-socioeconomic-status households in non-western settings. This mixed methods study describes the home language environment and early child language skills among households in a low-socioeconomic-status, peri-urban district of Chengdu, China, and identifies factors influencing parental investment in the home language environment. Audio recordings were collected from 81 peri-urban households with children ages 18–24 months and analysed using the Language Environment Analysis (LENATM) system. The Mandarin version of the MacArthur-Bates Communicative Development Inventory was administered to each child’s primary caregiver. The quantitative results revealed large variation in home language environments and child language skills among the sample, with relatively low average scores when compared to other Chinese samples. Qualitative interviews with a subset of 31 caregivers revealed that many caregivers face constraints on their knowledge of interactive parenting, compounded, in some households, by time constraints due to work or household responsibilities. The findings indicate a need for increased sources of credible parenting information for peri-urban caregivers of young children to promote investment in the home language environment.
