Perineal wound complications after vertical rectus abdominis myocutaneous flap and mesh closure following abdominoperineal surgery and pelvic exenteration of anal and rectal cancers: A meta‐analysis

Abstract

A meta-analysis research was implemented to appraise the perineal wound complications (PWCs) after vertical rectus abdominis myocutaneous (VRAM) flap and mesh closure (MC) following abdominoperineal surgery (AS) and pelvic exenteration (PE) of anal and rectal cancers. Inclusive literature research till April 2023 was done and 2008 interconnected researches were revised. Of the 20 picked researches, enclosed 2972 AS and PE of anal and rectal cancers persons were in the utilized researchers' starting point, 1216 of them were utilizing VRAM flap, and 1756 were primary closure (PC). Odds ratio (OR) and 95% confidence intervals (CIs) were utilized to appraise the consequence of VRAM flap in treating AS and PE of anal and rectal cancers by the dichotomous approach and a fixed or random model. VRAM flap had significantly lower PWCs (OR, 0.64; 95% CI, 0.42–0.98, p < 0.001), and major PWCs (OR, 0.50; 95% CI, 0.32–0.80, p = 0.004) compared to PC in AS and PE of anal and rectal cancers persons. However, VRAM flap and PC had no significant difference in minor PWCs (OR, 1; 95% CI, 0.54–1.85, p = 1.00) in AS and PE of anal and rectal cancer persons. VRAM flap had significantly lower PWCs, and major PWCs, however, no significant difference was found in minor PWCs compared to PC in AS and PE of anal and rectal cancers persons. However, caution needs to be taken when interacting with its values since there was a low sample size of most of the chosen research found for the comparisons in the meta-analysis.

Factors associated with the core dimensions of spiritual health among older adults with chronic obstructive pulmonary disease: A cross‐sectional study

Abstract

Aims

To investigate the level of spiritual health in older patients with chronic obstructive pulmonary disease (COPD) from the core dimensions and to explore its associated factors.

Design

A cross-sectional study.

Methods

Participants were recruited from four hospitals between September 2020 and June 2021, using a convenience sampling. Older patients with COPD (n = 162) completed the demographic and disease-related information questionnaires, Function Assessment of Chronic Illness Therapy Spiritual Scale, 10-item Connor-Davidson Resilience Scale, General Self-efficacy Scale, Social Support Rating Scale, COPD Assessment Test, 15-item Geriatric Depression Scale and modified Medical Research Council Dyspnea Scale. Descriptive statistics, Pearson and Spearman correlation analyses, t-tests, one-way ANOVA and multiple linear regression models were used.

Results

Older patients with COPD have a moderate level of spiritual health. The multiple linear regression analysis showed that psychological resilience, general self-efficacy, social support, symptom burden and monthly income were associated with the core dimensions of spiritual health.

Conclusion

Chinese older patients with COPD have a moderate level of spiritual health. Psychological resilience, general self-efficacy, social support, monthly income and symptom burden were associated with the core dimensions of spiritual health.

Impact

This study is the first to investigate the level of spiritual health in older patients with COPD from the core dimensions and to explore its associated factors, providing a basis for developing spiritual intervention programs. Our findings can help us realize that intervention strategies of psychological resilience, general self-efficacy and social support can all be used to enhance spiritual health. Nurses should focus on the spiritual health of older COPD patients with high symptom burden and low monthly income.

Patient or Public Contribution

Although we did not directly involve patients and the public because of the COVID-19 pandemic, the results of the study will be disseminated to patients and the public through WeChat and seminars.

Effects of multicomponent exercise on quality of life, depression and anxiety among stroke survivors: A systematic review and meta‐analysis

Abstract

Background

Current guidelines stress the importance of exercise, especially multicomponent exercise to older adults with chronic conditions.

Aim

To critically synthesise evidence that evaluates the effects of multicomponent exercise on quality of life, depression and anxiety after stroke.

Design

Systematic review and meta-analysis followed the PRISMA 2020 statement.

Methods

A systematic search of PubMed, Embase, Web of Science, Cochrane Library, CINAHL and PsycINFO from inception to 12 June 2023 was performed. Risk of bias was assessed using the Revised Cochrane risk-of-bias tool for randomised trials (RoB 2). Meta-analyses were conducted using Review Manager 5.4 and narrative syntheses were adopted whenever meta-analysis was inappropriate. The overall certainty of the evidence was rated using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach.

Results

Of 15,351 records identified, nine were eligible and data were available for seven randomised controlled trials, three of which were identified as having a high risk of bias, one as low risk, and five as having some concerns. Subgroup pooled analyses indicated that multicomponent exercise engaged in longer exercise sessions (>60 min) was effective in improving quality of life immediately post-intervention and through 3–6 months post-intervention. However, multicomponent exercise did not significantly affect depression and anxiety.

Conclusions

Multicomponent exercise with longer duration of exercise sessions has promising effects on both short- to medium-term quality of life among stroke survivors.

Patient or Public Contribution

This does not apply to our work as it is a review paper.

Relevance to Clinical Practice

Healthcare providers could consider encouraging the patients to participate in multicomponent exercise sessions for more than 60 min. It is important to note that stroke survivors should be supervised by trained personnel at the beginning of the training.

Registration

The protocol was registered on PROSPERO.

The role of programmed cell death in diabetic foot ulcers

Abstract

Diabetic foot ulcer, is a chronic complication afflicting individuals with diabetes, continue to increase worldwide, immensely burdening society. Programmed cell death, which includes apoptosis, autophagy, ferroptosis, necroptosis and pyroptosis, has been increasingly implicated in the pathogenesis of diabetic foot ulcer. This review is based on an exhaustive examination of the literature on ‘programmed cell death’ and ‘diabetic foot ulcers’ via PubMed. The findings revealed that natural bioactive compounds, noncoding RNAs and certain proteins play crucial roles in the healing of diabetic foot ulcers through various forms of programmed cell death, including apoptosis, autophagy, ferroptosis and pyroptosis.

Effect of minimally invasive versus conventional aortic root replacement on transfusion and postoperative wound complications in patients: A meta‐analysis

Abstract

We examined whether small incision aortic root replacement could reduce the amount of blood transfusion during operation and the risk of postoperative complications. An extensive e-review of the 4 main databases (PubMed, Cochrane, Web of Science and EMBASE) was carried out to determine all the published trials by July 2023. The search terms used were associated with partial versus full sternotomy and aortic root. This analysis only included the study articles that compared partial and full sternotomy. After excluding articles based on titles or abstracts, selected full-text articles had reference lists searched for any potential further articles. We analysed a total of 2167 subjects from 10 comparable trials. The minimally invasive aortic root graft in breastbone decreased the duration of hospitalization (MD, −2.58; 95% CI, −3.15, −2.01, p < 0.0001) and intraoperative red blood cell transfusion (MD, −1.27; 95% CI, −2.34, −0.19, p = 0.02). However, there were no significant differences in wound infection (OR, 0.88; 95% CI, 0.16, 4.93, p = 0.88), re-exploration for bleeding (OR, 0.96; 95% CI, 0.60, 1.53, p = 0.86), intraoperative blood loss (MD, −259.19; 95% CI, −615.11, 96.73, p = 0.15) and operative time (MD, −7.39; 95% CI, −19.10, 4.32, p = 0.22); the results showed that the microsternotomy did not differ significantly from that of the routine approach. Small sternotomy may be an effective and safe substitute for the treatment of the aorta root. Nevertheless, the wide variety of data indicates that larger, well-designed studies are required to back up the current limited literature evidence showing a benefit in terms of complications like postoperative wound infections or the volume of intraoperative red blood cell transfusion.

Effects of negative pressure wound therapy on surgical site wound infections after cardiac surgery: A meta‐analysis

Abstract

We conducted a comprehensive analysis to evaluate the benefits of negative pressure wound therapy (NPWT) versus traditional dressings in preventing surgical site infections in patients undergoing cardiac surgery. We thoroughly examined several databases, including PubMed, EMBASE, Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP, Chinese Biomedical Literature Database (CBM) and Wanfang, from inception until July 2023. Two independent researchers were responsible for the literature screening, data extraction and quality assessment; analyses were performed using RevMan 5.4 software. Thirteen studies comprising 8495 patients were deemed relevant. A total of 2685 patients were treated with NPWT, whereas 5810 received conventional dressings. The findings revealed that NPWT was more effective in reducing surgical site infections after cardiac surgery than conventional dressings (4.88% vs. 5.87%, odds ratio [OR]: 0.50, 95% confidence intervals [CIs]: 0.40–0.63, p < 0.001). Additionally, NPWT was more effective in reducing deep wound infections (1.48% vs. 4.15%, OR: 0.36, 95% CI: 0.23–0.56, p < 0.001) and resulted in shorter hospital stays (SMD: -0.33, 95% CIs: −0.54 to −0.13, p = 0.001). However, the rate of superficial wound infections was not significantly affected by the method of wound care (3.72% vs. 5.51%, OR: 0.63, 95% CI: 0.32–1.23, p = 0.180). In conclusion, NPWT was shown to be advantageous in preventing postoperative infections and reducing hospital stay durations in patients undergoing cardiac surgery. Nonetheless, given the limitations in the number and quality of the included studies, further research is recommended to validate these findings.

Effect of dexmedetomidine combined with local infiltration analgesia on postoperative wound complications in patients with total knee arthroplasty: A meta‐analysis

Abstract

Dexmedetomidine has been demonstrated to be effective in the management of pain in total knee replacement (TKA). Nevertheless, a combination of a local anaesthetic and a dose of dexmedetomidine might be a better choice for post-operative pain management of TKA. The aim of this research is to determine if the combination of a local anaesthetic with dexmedetomidine during a knee replacement operation can decrease the post-operation pain. Furthermore, the effectiveness and security of dexmedetomidine combined with topical anaesthetic were evaluated for the management of post-operative TKA. Based on the research results, the author made a research on the basis of four big databases. The Cochrane Handbook on Intervention Systems Evaluation has also evaluated the quality of the literature. Seven randomized controlled trials have been established from this. It was found that the combination of local anaesthesia and dexmedetomidine had a greater effect on postoperative pain in 4 h (mean difference [MD], −0.9; 95% CI, −1.71, −0.09; p = 0.03), 8 h (MD, −0.52; 95% CI, −0.66, −0.38; p < 0.0001), 12 h (MD, −0.72; 95% CI, −1.04, −0.40; p < 0.0001), 24 h (MD, −0.49; 95% CI, −0.83, −0.14; p = 0.006), 48 h (MD, −0.51; 95% CI, −0.92, −0.11; p = 0.01). Nevertheless, because of the limited number of randomized controlled trials covered by this meta-analysis, caution should be exercised with regard to data treatment. More high quality research will be required to confirm the results.

Effect of intramedullary nail fixation and internal plate fixation in distal tibia fracture surgery on post‐operative wound infection in patients: A meta‐analysis

Abstract

Distal tibial fracture is the most commonly seen type of fracture of the lower extremities. Both intramedullary nail fixation (INF) and plate fixation (PF) have been used to treat distal tibial fractures, but the best way to treat them is still in dispute. The purpose of this meta-analysis is to compare INF versus PF fixation with respect to the incidence of injury. For studies that have been published between inception and June 2023, a systematic review has been carried out on PubMed, Embase, Cochrane Library and Web of Scientific databases. All of the trials that looked at INF and PF-related complications were enrolled. Data from the 13 primary results were analysed with RevMan 5.3. The meta-analyses comprised 13 randomized controlled trials (RCTs). INF indicates that there is a tendency for patients with distal tibia fractures to reduce the risk of operative site infection (odds ratio [OR], 2.09; 95% confidence interval [CI], 1.40, 3.13; p = 0.0003) after surgery compared with PF. INF resulted in a reduction in total wound complications (OR, 14.20; 95% CI, 1.81, 111.57; p = 0.01) but shortened operation time (mean difference, 13.03; 95% CI, 2.08, 23.99; p = 0.02). In view of these findings, INF seems to be a preferred method of surgery for the treatment of distal tibial fractures with respect to the reduction of post-operative wound complications.

Effect of two different laparoscopic techniques on post‐operative wound complications in patients with benign gynaecological diseases: A meta‐analysis

Abstract

Single-port laparoscopy (SPL) has existed for several years. This meta-analysis was conducted to evaluate the efficacy of SPL compared with conventional laparoscopy (CL) in the treatment of benign gynecologic adnexal lesions. The purpose of this meta-analysis is to evaluate the superiority of SPL versus CL in the treatment of post-operative wound pain. The study looked for English-language publications from PubMed, Embase, Cochrane Library and the Web of Science until June 2023. The main result was the visual analogue scale (VAS) after 2, 4, 6, 8, 12, 24 and 48 h after operation. The paper contains 10 related papers by means of e-search. Of these, 4 were randomized controlled trials (RCTs), while 6 were non-RCTs. The results indicated that SPL and CL were significantly different after 2, 24 and 48 h after operation. SPL had lower post-operative pain after 2 h compared with CL (MD, −0.6; 95% CI, −0.98, −0.21; p = 0.002). After the operation, SPL also had a lower incidence of post-operative pain after 24 h compared with CL (MD, −0.59; 95% CI, −1.12, −0.06; p = 0.03). And the difference in pain was at 48 h after the most significant (MD, −0.49; 95% CI, −0.75, −0.23; p = 0.0002). But after 6, 8 and 12 h after operation, there was no significant difference in the degree of pain. Thus, SPL operations may result in a lower degree of pain than CL in both the post-operative and far post-operative phase.

Prevalence and risk factors of subsyndromal delirium among postoperative patients: A systematic review and meta‐analysis

Abstract

Aim

The aim of this study is to determine the prevalence and risk factors for subsyndromal delirium in the postoperative patient.

Design

A systematic review and meta-analysis.

Methods

The Review Manager 5.3 statistics platform and the Newcastle-Ottawa Scale were used for quality evaluation.

Data Sources

The following databases were searched: PubMed, Web of Science, EMBASE, The Cochrane Library, Scopus and EBSCO from January 2000 to December 2021. Additional sources were found by looking at relevant articles' citations.

Results

A total of 1744 titles were originally identified, and five studies including 962 patients were included in the systematic review, with a pooled prevalence of postoperative subsyndromal delirium (PSSD) of 30% (95% CI: 0.28–0.32). Significant risk variables for PSSD were older age, low levels of education (≤9 years), cognitive impairment, higher comorbidity score, and the duration of operation.

Conclusion

PSSD is prevalent and is associated with a variety of risk factors as well as low academic performance.

Impact

Identification and clinical management of patients with PSSD should be improved. Future research on PSSD risk factors should look at a wider range of intraoperative and postoperative risk factors that can be changed.

Effectiveness of dyadic interventions among cancer dyads: An overview of systematic reviews and meta‐analyses

Abstract

Aims and Objective

To summarize evidence from systematic reviews (SRs)/meta-analyses (MAs) regarding the impact of dyadic interventions delivered to both members of a cancer dyad, including a cancer patient and caregiver (e.g. family caregiver, intimate partner).

Design

This overview of SRs was conducted in accordance with the preferred reporting items for overviews of reviews statement.

Methods

A comprehensive search of multiple databases, including PubMed, Cochrane Library, Embase, CINAHL, Web of Science, China National Knowledge Infrastructure and Wan Fang. The methodological and reporting quality of SRs and MAs was assessed using the Assessing the Methodological Quality of Systematic Reviews 2. The quality of the included SRs/MAs was evaluated using the Grades of Recommendations, Assessment, Development and Evaluation approach.

Results

Eighteen SRs/MAs undertook quantitative synthesis to assess the impact of dyadic interventions on cancer dyads. Both the credibility of the SRs/MAs and the evidence quality of the outcome measures were below satisfactory standards. Prior SRs/MAs revealed several limitations such as lack of pre-published protocols or research objectives, failure to report excluded studies and insufficient details on funding sources for individual studies.

Conclusions

Dyadic interventions may prove advantageous for the physical health and dyadic adjustment of cancer dyads. Nevertheless, the reported results of dyadic interventions on the psychological health of patient–caregiver dyads affected by cancer are inconsistent. Thus, rigorous and comprehensive studies are requisite to establish reliable evidence for conclusive determinations.

Relevance to Clinical Practice

The findings of this overview can guide healthcare practitioners when considering the use of dyadic interventions for cancer dyads. Moreover, these findings have the potential to enhance the integration of these approaches into clinical practice.

Patient or Public Contribution

Our paper presents an overview of systematic reviews, and therefore, such specific details may not be relevant to our study.

Latent profile analysis of nurses perceived professional benefits in China: a cross-sectional study

Por: Sun · C. · Jiang · H. · Yao · Q. · Wang · X. · Wen · X. · Liu · H.
Objective

To identify profiles of nurses’ perceived professional benefits as well as their predictors.

Design

Cross-sectional study.

Setting

The study was carried out online in China.

Methods

From 6 July to 27 July 2022, a total of 1309 registered nurses participated in the survey by convenient sampling. We collected the Nurses’ Perceived Professional Benefits Questionnaire and demographic data. Using latent profile analysis (LPA), subgroups of nurses’ perceived professional benefits were identified. Moreover, univariate and multinomial logistic regression analyses were conducted to find the factors that were linked with the profiles.

Results

The survey was validly completed by 1309 nurses, with a 92.9% effective return rate. The findings of the LPA demonstrated three unique profiles: low-perceived professional benefits (11.8%), moderate-perceived professional benefits (57.1%) and high-perceived professional benefits (31.1%). There was a correlation between marital status, the number of night shifts per month and leadership role.

Conclusions

According to our research, registered nurses have three unique professional benefit profiles. In order to sustain the nursing workforce, despite the fact that nurses get a high level of professional benefits, interventions are necessary to increase nurses’ perception of their professional value.

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

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.

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.

Effectiveness of lipid-lowering therapy on mortality and major adverse cardiovascular event outcomes in patients undergoing percutaneous coronary intervention: a network meta-analysis of randomised controlled trials

Por: Deng · C.-J. · Yan · J. · Zheng · Y.-Y. · Wu · T.-T. · Pan · Y. · Hou · X.-G. · Wang · S.-F. · Sirajidin · S. · Aimaitijiang · M. · Xie · X.
Background

Emergency percutaneous coronary intervention (PCI) can quickly restore myocardial perfusion after acute coronary syndrome. Whether and which lipid-lowering regimens are effective in reducing major adverse cardiovascular events (MACEs) and mortality risk after PCI remain unclear.

Objective

This study assessed the benefits of different lipid-lowering regimens on the risk of MACEs and mortality in the post-PCI population by network meta-analysis.

Methods

Public databases, including PubMed, Embase and the Cochrane Library, were searched from inception to August 2022. Randomised controlled trials (RCTs) on lipid-lowering regimens in post-PCI populations were included and analysed. The outcomes were the incidence of all-cause mortality and MACEs, whether reported as dichotomous variables or as HRs.

Results

Thirty-nine RCTs were included. For MACEs, alirocumab plus rosuvastatin (OR: 0.18; 95% CI: 0.07 to 0.44), evolocumab plus ezetimibe and statins (OR: 0.19; 95% CI: 0.06 to 0.59), eicosapentaenoic acid (EPA) plus pitavastatin (HR: 0.67; 95% CI: 0.49 to 0.96) and icosapent ethyl plus statins (HR: 0.73; 95% CI: 0.62 to 0.86) had significant advantages and relatively high rankings. For mortality, rosuvastatin (OR: 0.30; 95% CI: 0.11 to 0.84), ezetimibe plus statins (OR: 0.55; 95% CI: 0.43 to 0.89) and icosapent ethyl plus statins (OR: 0.66; 95% CI: 0.45 to 0.96) had significant advantages compared with the control.

Conclusion

EPA, especially icosapent ethyl, plus statins had a beneficial effect on reducing the risk of MACEs and mortality in post-PCI patients. Proprotein convertase subtilisin/kexin type-9 inhibitors plus statins were able to reduce the risk of MACEs, but the risk of mortality remained unclear.

A meta‐analysis of the effectiveness of antibacterial bone cement in the treatment of diabetic foot skin wound infections

Abstract

A meta-analysis research was implemented to appraise the effect of antibiotic bone cement (ABC) in treating infected diabetic foot wounds (IDFWs). Inclusive literature research till April 2023 was done and 1237 interconnected researches were revised. The 15 selected researches enclosed 895 IDFWs persons were in the utilized researchers' starting point, 449 of them were utilizing ABC, and 446 were in the control group. Odds ratio and 95% confidence intervals were utilized to appraise the consequence of ABC in treating IDFWs by the contentious approach and a fixed or random model. ABC had significantly lower wound healing time (MD, −9.83; 95% CI, −12.45–−7.20, p < 0.001), and time to bacterial conversion of the wound (MD, −7.30; 95% CI, −10.38–−4.32, p < 0.001) compared to control in IDFWs persons. However, caution needs to be taken when interacting with its values since there was a low sample size of most of the chosen research found for the comparisons in the meta-analysis.

Por: Li · F. · Wang · Z. · Li · S. · Liu · W. · Li · Y. · Jiang · C. · Tian · Y. · Cui · W. · Zhang · X. · Zhang · J. · Xu · Y.
Objective

To investigate the association of fat and lean mass in specific regions with all-cause and cardiovascular-related mortality.

Design

Population based cohort study.

Setting

US National Health and Nutrition Examination Survey (2003–2006 and 2011–2018).

Participants

22 652 US adults aged 20 years or older.

Exposures

Fat and lean mass in specific regions obtained from the whole-body dual-energy X-ray absorptiometry.

Main outcome measures

All-cause and cardiovascular-related mortality.

Results

During a median of 83 months of follow-up, 1432 deaths were identified. Associations between body composition metrics and mortality risks were evident above specific thresholds. For all-cause mortality, Android fat mass showed elevated HRs above 2.46 kg (HR: 1.17, 95% CI 1.02 to 1.34), while Android lean mass (ALM) had similar trends above 2.75 kg (HR: 1.17, 95% CI 1.03 to 1.33), and Android total mass above 5.75 kg (HR: 1.08, 95% CI 1.01 to 1.16). Conversely, lower HRs were observed below certain thresholds: Gynoid fat mass (GFM) below 3.71 kg (HR: 0.72, 95% CI 0.56 to 0.93), Gynoid lean mass below 6.44 kg (HR: 0.77, 95% CI 0.64 to 0.92), and Gynoid total mass below 11.78 kg (HR: 0.76, 95% CI 0.70 to 0.84). Notably, below 0.722 kg, the HR of visceral adipose tissue mass (VATM) was 1.25 (95% CI 1.04 to 1.48) for all-cause mortality, and above 3.18 kg, the HR of total abdominal fat mass was 2.41 (95% CI 1.15 to 5.05). Cardiovascular-related mortality exhibited associations as well, particularly for Android fat mass (AFM) above 1.78 kg (HR: 1.22, 95% CI 1.01 to 1.47) and below 7.16 kg (HR: 0.50, 95% CI 0.36 to 0.69). HRs varied for Gynoid total mass below and above 10.98 kg (HRs: 0.70, 95% CI 0.54 to 0.93, and 1.12, 95% CI 1.02 to 1.23). Android per cent fat, subcutaneous fat mass (SFM), AFM/GFM, and VATM/SFM were not statistically associated with all-cause mortality. Android per cent fat, Gynoid per cent fat, AFM/GFM, and VATM/SFM were not statistically associated with cardiovascular-related mortality. Conicity index showed that the ALM/GLM had the highest performance for all-cause and cardiovascular-related mortality with AUCs of 0.785, and 0.746, respectively.

Conclusions

The relationship between fat or lean mass and all-cause mortality varies by region. Fat mass was positively correlated with cardiovascular mortality, regardless of the region in which they located. ALM/GLM might be a better predictor of all-cause and cardiovascular-related mortality than other body components or body mass index.

Introduction

The strategy for initiating antithrombotic therapy to prevent bioprosthetic valve thrombosis (BPVT) after transcatheter aortic valve replacement (TAVR) remains uncertain. There is still lacking evidence on the efficacy and safety of early 6 months usage of single-antiplatelet therapy (SAPT) or oral anticoagulant (OAC) after TAVR in patients without anticoagulant indications.

Methods and analysis

This is a multicentre, randomised controlled, open-label trial, and 650 patients undergoing TAVR from 13 top TAVR centres in China will be recruited. Each eligible participant will be randomly assigned to two groups (1:1 ratio) as (1) SAPT (aspirin 75–100 mg for 6 months) group or (2) OAC group (warfarin, therapeutic international normalised ratio at 1.8–2.5 for 6 months), both followed by sequential aspirin 75–100 mg for 6 months. Participants in both groups will be invited for three follow-up visits of 1, 6 and 12 months after discharge. We will use both the net clinical benefit endpoint (composite of all-cause mortality, myocardial infarction, stroke/transient ischaemic attacks, peripheral artery thrombosis, intracardiac thrombosis and major bleeding and disabling or life-threatening bleeding) and the BPVT endpoint evaluated by four-dimensional CT as our primary endpoints.

Objectives

A well-functioning health system ensures timely routine measles vaccinations for age-appropriate children, minimising measles risk. However, there is limited knowledge about the impact of the performance of immunisation programmes in health systems on the timeliness of measles vaccination. This study aimed to identify health system barriers to timely routine measles vaccination in rural southwest China, integrating the perspectives of township vaccination professionals and village doctors.

Design, setting and participants

Qualitative study among township vaccination professionals and village doctors in rural Guangxi, southwest China.

Methods

20 focus group discussions (FGDs) at township level and 120 in-depth interviews (IDIs) at village level, based on a four-theme framework. We used convenience sampling to recruit 60 township vaccination professionals and 120 village doctors in 2015. Instruments used were a semistructured questionnaire and interview outlines. We collected township and village-level data focusing on themes of health resources allocation, pattern of vaccination services, management and supervision of vaccination services, and perceptions of vaccination policy. The FGDs and IDIs were audio-recorded and transcribed. Braun and Clarke’s thematic analysis approach was adopted to synthesise findings into meaningful subthemes, narrative text and illustrative quotations.

Results

The health system barriers to timely routine vaccinations were explored across four themes. Barriers in the health resources allocation theme comprised (1) inadequacy of vaccination-related human resources (eg, lack of township vaccination professionals and lack of young village doctors), and (2) incompatible and non-identical information system of vaccination services across regions. Barriers in the pattern of vaccination services theme included inflexible vaccination services models, for example, routine vaccination services being offered monthly on fixed vaccination days, limited numbers of vaccination days per month, vaccination days being set on non-local market days, vaccination days being clustered into a specific period and absence of formal vaccination appointments. Ineffective economic incentive mechanism was identified as a barrier in the management and supervision of vaccination services theme. Low-degree participation of village doctors in routine vaccination services was identified as a barrier in the perceptions of vaccination policy theme.

Conclusions

We encourage policymakers and stakeholders to apply these findings to improve the timeliness of routine vaccination. Barriers to timely routine vaccination include inadequate allocation of vaccination-related resources and inflexible vaccination service delivery models. Financial and non-financial incentives should be used to retain and recruit vaccination professionals and village doctors. Strengthening information systems with unified data standards enables cross-regional data exchange. Optimising immunisation services and rationalising vaccination days could eliminate health system barriers and improve vaccination timeliness in rural China.
