Por: Li · J. · Ou · J. · Liu · Y. · Shen · C. · Chen · X. · Li · Y. · Zhao · J. · Xu · J. · Zhang · Y. · Wang · L. — Marzo 20th 2024 at 05:26
Introduction

Neck pain is a global health problem that can cause severe disability and a huge medical burden. Clinical practice guideline (CPG) is an important basis for clinical diagnosis and treatment. A high-quality CPG plays a significant role in clinical practice. However, the quality of the CPGs for neck pain lacks comprehensive assessment. This protocol aims to evaluate the methodological, recommendation, reporting quality of global CPGs for neck pain and identify key recommendations and gaps that limit evidence-based practice.

Method

CPGs from January 2013 to November 2023 will be identified through a systematic search on 13 scientific databases (PubMed, Cochrane Library, Embase, etc) and 7 online guideline repositories. Six reviewers will independently evaluate the quality of CPGs for neck pain by using the Appraisal of Guidelines for Research and Evaluation, the Appraisal of Guidelines Research and Evaluation-Recommendations Excellence and the Reporting Items for Practice Guidelines in Healthcare tools. Intraclass correlation coefficient will be used to test the consistency of the assessment. We will identify the distribution of evidence and recommendations in each evidence-based CPGs for neck pain and regrade the level of evidence and strength of recommendations by adopting the commonly used Grading of Recommendations, Assessment, Development and Evaluations system. The key recommendations based on high-quality evidence will be summarised. In addition, we will categorise CPGs by different characteristics and conduct a subgroup analysis of the results of assessment.

Ethics and dissemination

No subjects will be involved in this systematic review, so there is no need for ethical approval. The finding of this review will be summarised as a paper for publication in a peer-reviewed journal.

Association of thyroid autoantibodies and diabetic kidney disease in hospitalised patients with type 2 diabetes mellitus: a cross-sectional study from a Chinese university hospital

Por: Wang · Z. · Wang · F. · Liu · C. · Zhang · L. — Marzo 19th 2024 at 04:02
Objectives

To analyse and explore the association between thyroid autoantibodies and diabetic kidney disease (DKD) in patients with type 2 diabetes mellitus (T2DM).

Design

A cross-sectional study.

Setting

Patients were from the inpatient unit at The Second Endocrinology Department of Shengjing Hospital Affiliated to China Medical University (Shenyang, China) between January 2015 and September 2019.

Participants

A total of 150 Chinese adults with T2DM were included in the study, including 83 men and 67 women. Their age ranged between 25 and 92 years.

Methodology

They grouped by the presence of DKD, urine albumin-to-creatinine ratio (UACR), estimated glomerular filtration rate, and levels of thyroid peroxidase antibodies (TPOAb) and thyroglobulin antibodies (TgAb). Data on the patients’ general characteristics and laboratory measurements (levels of fasting plasma glucose, glycated haemoglobin, and albumin; renal function; and thyroid function) were collected. Binary logistic regression was performed to identify risk factors for DKD.

Results

The level of TPOAb, the positivity rates of TPOAb (p

Conclusions

TPOAb-positive status is in association with DKD in patients with T2DM. Large scale, prospective cohort studies are warranted to confirm our findings.

Por: Ma · X. · Wu · S. · Zhang · X. · Chen · N. · Yang · C. · Yang · C. · Cao · M. · Du · K. · Liu · Y. — Marzo 15th 2024 at 14:25
Objectives

This study aimed to investigate the impact of adjuvant chemotherapy (ACT) on survival outcomes in older women with hormone receptor-positive and human epidermal growth factor receptor 2-negative (HR+/HER2–) breast cancer (BC).

Design

A retrospective cohort study using data from the Surveillance, Epidemiology, and End Results database, which contains publicly available information from US cancer registries.

Setting and participants

The study included 45 762 older patients with BC aged over 65 years diagnosed between 2010 and 2015.

Methods

Patients were divided into two groups based on age: 65–79 years and ≥80 years. Propensity score matching (PSM) was employed to balance clinicopathological characteristics between patients who received ACT and those who did not. Data analysis used the 2 test and Kaplan-Meier method, with a subgroup analysis conducted to identify potential beneficiaries of ACT.

Outcome measures

Overall survival (OS) and cancer-specific survival (CSS).

Results

Due to clinicopathological characteristic imbalances between patients with BC aged 65–79 years and those aged ≥80 years, PSM was used to categorise the population into two groups for analysis: the 65–79 years age group (n=38 128) and the ≥80 years age group (n=7634). Among patients aged 65–79 years, Kaplan-Meier analysis post-PSM indicated that ACT was effective in improving OS (p

Conclusions

Patients with HR+/HER2– BC ≥80 years of age may be considered exempt from ACT because no benefits were found in terms of OS and CSS.

Human umbilical cord mesenchymal stem cell therapy for renal dysfunction in Alport syndrome: protocol for an open-label, single-arm trial in China

Por: Huang · L. · Zou · J. · Zhang · Y. · Gu · J. · Wu · J. · Zhang · C. — Marzo 15th 2024 at 14:25
Introduction

Alport syndrome (AS) is one of the most common fatal hereditary renal diseases in human, with a high risk of progressing to end-stage renal disease without effective treatments. Mesenchymal stem cells (MSCs) have recently emerged as a promising therapeutic strategy for chronic kidney disease. However, the safety and therapeutic potential of MSC transfusion for patients with AS are still need to be confirmed. Therefore, we have designed a clinical trial to evaluate the hypothesis that intravenous infusion of human umbilical cord-derived MSC (hUC-MSC) is safe, feasible, and well-tolerated in children with AS.

Methods and analysis

We report the protocol of the first prospective, open-label, single-arm clinical trial to evaluate the safety and preliminary efficacy of hUC-MSC transfusion in children with early-stage AS. Paediatric patients diagnosed with AS who have persistent albuminuria will be candidates for screening. Twelve eligible patients are planned to recruit and will receive hUC-MSC infusions under close safety monitoring, and complete the efficacy assessments at scheduled follow-up visits. The primary endpoints include the occurrence of adverse events to assess safety and the albuminuria level for efficacy evaluation. Secondary endpoint assessments are based on haematuria and glomerular filtration measurements. Each patient’s efficacy endpoints will be evaluated against their baseline levels. Additionally, the underlying mechanism of hUC-MSC therapy will be explored through transcriptomic and proteomic analysis of blood and urine samples.

Ethics and dissemination

The protocol (V.1.0, date 17 January 2015) was approved by the institutional review board of the Affiliated Taihe Hospital of Hubei University of Medicine (ethical approval 03 March 2015). Written informed consent will be obtained from the patient and/or guardians before study specific process. In addition to publication in a peer-reviewed scientific journal, a lay summary of study will be available for participants and the public on the Chinese Organization for Rare Disorders website (http://www.cord.org.cn/).

Inhaled Nitric Oxide ReDuce postoperatIve pulmoNAry complicaTions in patiEnts with recent COVID-19 infection (INORDINATE): protocol for a randomised controlled trial

Por: Zheng · Z. · Wang · L. · Wang · S. · Fan · Q. · Zhang · H. · Luo · G. · Gao · B. · Yang · X. · Zhao · B. · Wang · X. · Dong · H. · Nie · H. · Lei · C. — Marzo 15th 2024 at 02:35
Background

A history of SARS-CoV-2 infection has been reported to be associated with an increased risk of postoperative pulmonary complications (PPCs). Even mild PPCs can elevate the rates of early postoperative mortality, intensive care unit (ICU) admission and prolong the length of ICU and/or hospital stays. Consequently, it is crucial to develop perioperative management strategies that can mitigate these increased risks in surgical patients who have recently been infected with SARS-CoV-2. Accumulating evidence suggests that nitric oxide (NO) inhalation might be effective in treating COVID-19. NO functions in COVID-19 by promoting vasodilation, anticoagulation, anti-inflammatory and antiviral effects. Therefore, our study hypothesises that the perioperative use of NO can effectively reduce PPCs in patients with recent SARS-CoV-2 infection.

Method and analysis

A prospective, double-blind, single-centre, randomised controlled trial is proposed. The trial aims to include participants who are planning to undergo surgery with general anaesthesia and have been recently infected with SARS-CoV-2 (within 7 weeks). Stratified allocation of eligible patients will be performed at a 1:1 ratio based on the predicted risk of PPCs using the Assess Respiratory Risk in Surgical Patients in Catalonia risk index and the time interval between infection and surgery.

The primary outcome of the study will be the presence of PPCs within the first 7 days following surgery, including respiratory infection, respiratory failure, pleural effusion, atelectasis, pneumothorax, bronchospasm and aspiration pneumonitis. The primary outcome will be reported as counts (percentage) and will be compared using a two-proportion 2 test. The common effect across all primary components will be estimated using a multiple generalised linear model.

Ethics and dissemination

The trial is approved by the Institutional Review Board of Xijing Hospital (KY20232058-F1). The findings, including positive, negative and inconclusive results, will be published in scientific journals with peer-review processes.

Deep learning model to predict lupus nephritis renal flare based on dynamic multivariable time-series data

Por: Huang · S. · Chen · Y. · Song · Y. · Wu · K. · Chen · T. · Zhang · Y. · Jia · W. · Zhang · H.-T. · Liang · D.-D. · Yang · J. · Zeng · C.-H. · Li · X. · Liu · Z.-H. — Marzo 15th 2024 at 02:35
Objectives

To develop an interpretable deep learning model of lupus nephritis (LN) relapse prediction based on dynamic multivariable time-series data.

Design

A single-centre, retrospective cohort study in China.

Setting

A Chinese central tertiary hospital.

Participants

The cohort study consisted of 1694 LN patients who had been registered in the Nanjing Glomerulonephritis Registry at the National Clinical Research Center of Kidney Diseases, Jinling Hospital from January 1985 to December 2010.

Methods

We developed a deep learning algorithm to predict LN relapse that consists of 59 features, including demographic, clinical, immunological, pathological and therapeutic characteristics that were collected for baseline analysis. A total of 32 227 data points were collected by the sliding window method and randomly divided into training (80%), validation (10%) and testing sets (10%). We developed a deep learning algorithm-based interpretable multivariable long short-term memory model for LN relapse risk prediction considering censored time-series data based on a cohort of 1694 LN patients. A mixture attention mechanism was deployed to capture variable interactions at different time points for estimating the temporal importance of the variables. Model performance was assessed according to C-index (concordance index).

Results

The median follow-up time since remission was 4.1 (IQR, 1.7–6.7) years. The interpretable deep learning model based on dynamic multivariable time-series data achieved the best performance, with a C-index of 0.897, among models using only variables at the point of remission or time-variant variables. The importance of urinary protein, serum albumin and serum C3 showed time dependency in the model, that is, their contributions to the risk prediction increased over time.

Conclusions

Deep learning algorithms can effectively learn through time-series data to develop a predictive model for LN relapse. The model provides accurate predictions of LN relapse for different renal disease stages, which could be used in clinical practice to guide physicians on the management of LN patients.

Cost-effectiveness of the top 100 drugs by public spending in Canada, 2015-2021: a repeated cross-sectional study

Por: Gaudette · E. · Rizzardo · S. · Zhang · Y. · Pothier · K. R. · Tadrous · M. — Marzo 14th 2024 at 06:01
Objectives

To assess the distribution and spending by cost-effectiveness category among those drugs with the highest public spending levels in Canada.

Design

Repeated cross-sectional study.

Setting

The Canadian provinces of Manitoba, Ontario, New Brunswick, Nova Scotia, Prince Edward Island and Newfoundland.

Main outcomes and measures

Cost-effectiveness assessments by the Canadian Agency for Drugs and Technologies in Health (CADTH) for top-100 brand-name outpatient drugs by gross public plan spending in any year between 2015 and 2021 in Canada Institute for Health Information’s National Prescription Drug Utilization Information System data. Gross public plan spending by cost-effectiveness category.

Results

From 2015 to 2021, 152 brand-name drugs occupied a top-100 rank and were included in the analysis. Of those, 117 had been assessed by CADTH. During the 7-year period, there was an increase in both top-100 drugs with cost-effective (from 18 to 24) and cost-ineffective (from 29 to 41) assessments, while drugs not assessed or with an unclear assessment declined (from 31 to 19 and from 22 to 16, respectively). As a share of spending on top-100 drugs with an assessment, spending on cost-effective drugs was mostly stable at 40%–46% from 2015 to 2021, while spending on cost-ineffective drugs increased from 30% to 45%.

Conclusion

A large and growing share of public drug spending has been allocated to cost-ineffective drugs in Canada. Dedicating large budgets to such treatments prevents spending with greater health impact elsewhere in the healthcare system and could restrain the capacity to pay for groundbreaking pharmaceutical innovation in the future.

Exposure to early-life adversity and long-term trajectories of multimorbidity among older adults in China: analysis of longitudinal data from the China Health and Retirement Longitudinal Study

Por: Liu · H. · Zhang · M. · Zhang · X. · Zhao · X. — Marzo 14th 2024 at 06:01
Objectives

This study aimed to identify long-term distinct trajectories of multimorbidity with ageing from 50 to 85 years among Chinese older adults and examine the relationship between exposure to early-life adversity (ELA; including specific types of adversity and accumulation of different adversities) and these long-term multimorbidity trajectories.

Design

The group-based trajectory models identified long-term multimorbidity trajectories. Multinomial logistic regression models were used to examine the relationship between ELA and the identified multimorbidity trajectories.

Setting

This study used data from the China Health and Retirement Longitudinal Study (CHARLS, 2011–2018) and the 2014 Life History Survey.

Participants

We used data from 9112 respondents (aged 60 and above) of the 2018 wave of CHARLS.

Outcome measures

Each respondent’s history of chronic conditions and experiences of ELA were collected from the 2011–2018 waves of CHARLS and the 2014 Life History Survey.

Results

Four heterogeneous long-term trajectories of multimorbidity development were identified: ‘maintaining-low’ (19.1%), ‘low onset-rapidly increasing’ (23.3%), ‘middle onset-moderately increasing’ (41.5%) and ‘chronically-high’ (16.2%). Our findings indicated that the heterogeneity can be explained by ELA experiences. Across various types of different ELA experiences, exposure to food insufficiency (relative risk ratios from 1.372 (95% CI 1.190 to 1.582) to 1.780 (95% CI 1.472 to 2.152)) and parental quarrel/divorce (relative risk ratios from 1.181 (95% CI 1.000 to 1.394) to 1.262 (95% CI 1.038 to 1.536)) had the most prominent associations with health deterioration. The accumulation of more different ELA experiences was associated with a higher relative risk of developing more severe multimorbidity trajectories (relative risk ratio for five to seven ELAs and chronically high trajectory: 7.555, 95% CI 4.993 to 11.431).

Conclusions

There are heterogeneous long-term trajectories of multimorbidity in Chinese older adults, and the risk of multimorbidity associated with ELA accumulates over the lifespan. Our findings highlight the role of a supportive early-life family environment in promoting health development across the lifespan, advocating for the integration of life-course approaches to implementing health disparity interventions.

Por: Zhang · R. · Gao · M. · Li · W. · Liu · H. · Wang · S. · Wang · H. · Li · N. · Li · J. · Yu · Z. · Hu · G. · Leng · J. · Yang · X. — Marzo 13th 2024 at 05:20
Objectives

To explore associations between adverse birth outcomes and childhood overweight at 3–8 years of age.

Design

A prospective cohort study.

Setting

Six central urban districts of Tianjin, China.

Participants

1681 woman–child pairs.

Methods

1681 woman–child pairs were followed up for 8 years in Tianjin, China. Demographic and clinical information including birth outcomes was collected longitudinally, commencing from first antenatal care visit till postpartum period. Offspring height and weight were measured at 3–8 years of age. High and low weight/length ratios (WLR) at birth were, respectively, defined as ≥90th and ≤10th gestational week and sex-specific percentiles. Overweight for children at 3–5 and 6–8 years of age were, respectively, defined as body mass index (BMI)-for-age and -sex above the 2 z-score and 1 z-score curves of the WHO’s child growth standards. Binary logistic regression analysis was used to obtain ORs and 95% CI with a stepwise backward selection method to select independent predictors.

Primary outcomes measures

Childhood overweight.

Results

Of 1681 children, 10.7% (n=179) and 27.8% (n=468) developed overweight at 3–5 and 6–8 years of age, respectively. Large for gestational age (LGA) was associated with increased risk of overweight at 3–5 years of age (aOR: 1.86, 95% CI: 1.27 to 2.72) while high WLR at birth was associated with increased risk of overweight at 6–8 years of age (1.82, 1.41 to 2.34). Low WLR at birth was associated with decreased risk of overweight at 6–8 years of age (0.52, 0.30 to 0.90).

Conclusions

LGA and high WLR at birth predicted childhood overweight at 3–5 and 6–8 years of age, respectively. Low WLR at birth was associated with decreased risk of childhood overweight at 6–8 years of age.

Differences in inpatient performance of public general hospitals following implementation of a points-counting payment based on diagnosis-related group: a robust multiple interrupted time series study in Wenzhou, China

Por: Zhu · T. · Chen · C. · Zhang · X. · Yang · Q. · Hu · Y. · Liu · R. · Zhang · X. · Dong · Y. — Marzo 13th 2024 at 02:35
Objectives

This study measures the differences in inpatient performance after a points-counting payment policy based on diagnosis-related group (DRG) was implemented. The point value is dynamic; its change depends on the annual DRGs’ cost settlements and points of the current year, which are calculated at the beginning of the following year.

Design

A longitudinal study using a robust multiple interrupted time series model to evaluate service performance following policy implementation.

Setting

Twenty-two public general hospitals (8 tertiary institutions and 14 secondary institutions) in Wenzhou, China.

Intervention

The intervention was implemented in January 2020.

Outcome measures

The indicators were case mix index (CMI), cost per hospitalisation (CPH), average length of stay (ALOS), cost efficiency index (CEI) and time efficiency index (TEI). The study employed the means of these indicators.

Results

The impact of COVID-19, which reached Zhejiang Province at the end of January 2020, was temporary given rapid containment following strict control measures. After the intervention, except for the ALOS mean, the change-points for the other outcomes (p0.05), the uptrend of the CEI mean in tertiary institutions alleviated (p0.05).

Conclusions

This study showed a positive effect of the DRG policy in Wenzhou, even during COVID-19. The policy can motivate public general hospitals to improve their comprehensive capacity and mitigate discrepancies in treatment expenses efficiency for similar diseases. Policymakers are interested in whether the reform successfully motivates hospitals to strengthen their internal impetus and improve their performance, and this is supported by this study.

Willingness to purchase institutionalised elderly services and influencing factors among Chinese older adults: a nationwide cross-sectional study

Por: Zhu · R. · Hou · W. · Wang · L. · Zhang · C. · Guo · X. · Luo · D. · Wang · F. — Marzo 12th 2024 at 06:06
Objectives

In view of the serious ageing of China’s population and the low desire of elderly people to purchase institutionalised elderly care services, we explored the willingness of Chinese elderly people to purchase institutionalised elderly care services and its influencing factors.

Design

This was a cross-sectional study. Three multivariate logistic regression analysis models of the willingness of elderly people to purchase institutionalised elderly care services were established (model 1: ‘reluctance – willingness’; model 2: ‘reluctance – hesitation’; and model 3: ‘hesitation – willingness’) to explore the factors that influence elderly people’s willingness to purchase institutionalised elderly care services.

Setting

This study was based on the 2022 Psychology and Behaviour Investigation of Chinese Residents database.

Participants

Research data from 4123 older adults who met the requirements of this study were screened from the database.

Results

Of the 4123 respondents, roughly equal numbers had negative and positive attitudes towards purchasing institutionalised senior care services (1125, 27.3% vs 1079, 26.2%, respectively), and 1919 (46.5%) had hesitant attitudes. The analysis of model 1 showed that medical insurance participation, the number of children and siblings, chronic diseases and per capita monthly household income had an influential effect on the willingness of elderly people to purchase institutional care. In model 2, we found that factors such as per capita monthly household income and anxiety led to hesitancy among older adults to purchase institutionalised senior care services. In model 3, we further found that social support and health literacy led to a shift from hesitation to willingness to purchase institutionalised elderly care services.

Conclusion

The number of children, number of siblings, per capita monthly income of the family, medical insurance participation, health status, health literacy and social support were found to be the main factors influencing the purchase of institutionalised care by elderly individuals.

Appraising the quality standard of clinical practice guidelines related to central venous catheter-related thrombosis prevention: a systematic review of clinical practice guidelines

Por: Zhang · J. · Wu · Y. · Zhang · S. · Yao · W. · Bu · F. · Wang · A. · Hu · X. · Wang · G. — Marzo 12th 2024 at 06:06
Objective

To evaluate the quality and analyse the content of clinical practice guidelines regarding central venous catheter-related thrombosis (CRT) to provide evidence for formulating an evidence-based practice protocol and a risk assessment scale to prevent it.

Design

Scoring and analysis of the guidelines using the AGREE II and AGREE REX scales.

Data sources

Pubmed, Embase, Cochrane Library, Web of Science, CNKI, Wanfang, VIP, and the Chinese Biomedical Literature, and the relevant websites of the guideline, were searched from 1 January 2017 to 26 March 2022.

Eligibility criteria

Guidelines covering CRT treatment, prevention, or management were included from 1 January 2017 to 26 March 2022.

Data extraction and synthesis

Three independent reviewers systematically trained in using the AGREE II and AGREE REX scales were selected to evaluate these guidelines.

Results

Nine guidelines were included, and the quality grade results showed that three were at A-level and six were at B-level. The included guidelines mainly recommended the prevention measure of central venous CRT from three aspects: risk screening, prevention strategies, and knowledge training, with a total of 22 suggestions being recommended.

Conclusion

The overall quality of the guidelines is high, but there are few preventive measures for central venous CRT involved in the guidelines. All preventive measures have yet to be systematically integrated and evaluated, and no risk assessment scale dedicated to this field has been recommended. Therefore, developing an evidence-based practice protocol and a risk assessment scale to prevent it is urgent.

Effects of cluster nursing interventions on the prevention of pressure ulcers in intensive care units patients: A meta‐analysis

Por: Ai‐Guo Zhang · Ling Li · Yuan‐Li Li · Shun‐Xia Sun · Min Wang · Xiao‐Ling Tang — Marzo 18th 2024 at 06:14

Abstract

A meta-analysis was conducted to comprehensively evaluate the impact of cluster nursing interventions on the prevention of pressure ulcers (PUs) in intensive care unit (ICU) patients. Computer searches were performed in databases including Embase, Google Scholar, Cochrane Library, PubMed, Wanfang and China National Knowledge Infrastructure for randomized controlled trials (RCTs) implementing cluster nursing interventions for PUs prevention in ICU patients, with the search period covering the database inception to November 2023. Two researchers independently screened the literature, extracted data and conducted quality assessments. Stata 17.0 software was employed for data analysis. Overall, 17 RCTs involving 1463 ICU patients were included. The analysis showed that compared with conventional nursing, cluster nursing interventions significantly reduced the incidence of PUs (odds ratio: 0.24, 95% confidence intervals [CI]: 0.17–0.34, p < 0.001) and also significantly improved the levels of anxiety (standardized mean difference [SMD]: −1.39, 95% CI: −1.57 to 1.22, p < 0.001) and depression (SMD: −1.64, 95% CI: −2.02 to 1.26, p < 0.001) in ICU patients. This study indicates that the application of cluster nursing interventions in ICU patients can effectively reduce the incidence of PUs, as well as improve patients' anxiety and depression levels, thereby enhancing their quality of life, which is worth clinical promotion and application.

Por: Yihang Li · Xiaodong Hu · Ruhu Zhang · Nan Wu · Qingqing Xia · Peijie Gu — Marzo 15th 2024 at 00:30

Abstract

Neoadjuvant chemoimmunotherapy is becoming an increasingly important part of the management of lung cancer to facilitate surgical resection. This study aimed to summarize the treatment-related adverse events (TRAEs) and wound complications of neoadjuvant chemoimmunotherapy in non-small cell lung cancer (NSCLC). Eligible studies of neoadjuvant chemoimmunotherapy for NSCLC were identified from PubMed, Embase and Web of Science. The endpoints mainly included TRAEs and wound complications. Stata18 software was used for statistical analysis with p < 0.05 considered statistically significant. Twenty studies including a total of 1072 patients were eligible for this study. Among the patients who received neoadjuvant chemoimmunotherapy, the pooled prevalence of any grade TRAEs was 77% (95% confidence interval [CI] [0.64–0.86]), grade 1–2 TRAEs was 77% (95% CI [0.58–0.89]) and grade ≥3 TRAEs was 26% (95% CI [0.16–0.38]). Surgery-related complications rate was 22% (95% CI [0.14–0.33]). Among the wound complications, the pooled rate of air leakage was 10% (95% CI [0.04–0.23]), pulmonary/wound infection was 8% (95% CI [0.05–0.13]), bronchopleural fistula was 8% (95% CI [0.02–0.27]), bronchopulmonary haemorrhage was 3% (95% CI [0.01–0.05]), pneumonia was 5% (95% CI [0.02–0.10]), pulmonary embolism was 1% (95% CI [0.01–0.03]), pleural effusion was 7% (95% CI [0.03–0.14]) and chylothorax was 4% (95% CI [0.02–0.09]). Overall, neoadjuvant chemoimmunotherapy in NSCLC results a high incidence of grade 1–2 TRAEs but a low risk of increasing the incidence of ≥3 grade TRAEs and wound complications. These results need to be confirmed by more large-scale prospective randomized controlled trials and studies.

Effects of high tibial osteotomy compared with unicondylar knee arthroplasty on the surgical site wound infection and pain in patients with medial knee osteoarthritis

Por: Jingcheng Li · Yang Zhang · Yonghua Chen · Ying Li · Baifa Dai · Ping Liu — Marzo 13th 2024 at 14:38

Abstract

This study aims to comprehensively compare the effects of unicondylar knee arthroplasty (UKA) and high tibial osteotomy (HTO) on wound infection and pain in patients with medial knee osteoarthritis. A computerized search was conducted in Embase, PubMed, Google Scholar, China National Knowledge Infrastructure, Cochrane Library and Wanfang databases, from database inception to October 2023, for studies comparing UKA and HTO for medial knee osteoarthritis. Studies selection, data extraction and study quality evaluation were independently conducted by two researchers. Stata 17.0 software was employed for data analysis. Overall, 10 studies involving 870 patients with medial knee osteoarthritis were included. It was found that the UKA group had significantly lower wound visual analogue scale scores compared to the HTO group (SMD = -0.53, 95%CI: −0.87 to −0.20, p < 0.001). The incidence of wound infection in the UKA group was higher than in the HTO group (OR = 1.92, 95%CI: 0.65–5.69, p = 0.240), and the incidence of complications was lower (OR = 0.89, 95%CI: 0.52–1.54, p = 0.684), though these differences were not statistically significant. This study indicates that UKA is effective in alleviating postoperative wound pain in medial knee osteoarthritis. However, the rates of postoperative wound infection and complications are comparable to those of HTO. Clinicians should consider factors such as patient age and disease severity in making individualized treatment decisions.

Pharyngocutaneous fistula (PCF) is a major complication after total laryngectomy, with significant morbidity and mortality. Whether mechanical stapler closure of the pharynx reduces fistula rates compared to hand-sewn techniques remains unclear. We conducted an updated systematic review and meta-analysis to clarify this question. Five databases were systematically searched from inception through November 2023 for studies comparing stapler versus suture closure for fistula outcomes after laryngectomy. Odds ratios (OR) were pooled using random-effects models and fixed-effects models. Subgroup and sensitivity analyses were performed. Risk of bias was appraised using NHLBI tools. Nine studies with 803 patients were included. Mechanical closure significantly reduced fistula incidence versus suture closure (OR = 0.57, 95% CI 0.34–0.95, p = 0.03). Subgroup analysis found that stapling's protective effect varied by patient age, country/region, linear stapler size and female percentage. Stapling reduced fistula odds by 80% in the Turkey subgroup (OR = 0.20, 95% CI 0.09–0.50) but showed no benefit in other regions. Patients <60 years showed an 84% fistula reduction with stapling (OR = 0.17, 95% CI 0.06–0.45), whereas older subgroups did not. Linear stapler size of 60 mm significantly reduced fistula occurrence while 75 mm did not. There was no evidence that low female percentage mitigated stapling benefits. Mechanical stapler closure after total laryngectomy meaningfully reduces the likelihood of postoperative PCF formation compared to hand-sewn closure, especially for patients younger than 60 years old. The absolute risk reduction supports its utility to prevent this complication.

Abstract

Diabetic foot ulcers (DFUs) are a serious chronic complication of diabetes mellitus and a leading cause of disability and death in diabetic patients. However, current treatments remain unsatisfactory. Although macrophages are associated with DFU, their exact role in this disease remains uncertain. This study sought to detect macrophage-related genes in DFU and identify possible therapeutic targets. Single-cell datasets (GSE223964) and RNA-seq datasets (GSM68183, GSE80178, GSE134431 and GSE147890) associated with DFU were retrieved from the gene expression omnibus (GEO) database for this study. Analysis of the provided single-cell data revealed the distribution of macrophage subpopulations in the DFU. Four independent RNA-seq datasets were merged into a single DFU cohort and further analysed using bioinformatics. This included differential expression (DEG) analysis, multiple machine learning algorithms to identify biomarkers and enrichment analysis. Finally, key results were validated using reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and Western bolt. Finally, the findings were validated using RT-qPCR and western blot. We obtained 802 macrophage-related genes in single-cell analysis. Differential expression analysis yielded 743 DEGs. Thirty-seven macrophage-associated DEGs were identified by cross-analysis of marker genes with macrophage-associated DEGs. Thirty-seven intersections were screened and cross-analysed using four machine learning algorithms. Finally, HMOX1 was identified as a potentially valuable biomarker. HMOX1 was significantly associated with biological pathways such as the insulin signalling pathway. The results showed that HMOX1 was significantly overexpressed in DFU samples. In conclusion, the analytical results of this study identified HMOX1 as a potentially valuable biomarker associated with macrophages in DFU. The results of our analysis improve our understanding of the mechanism of macrophage action in this disease and may be useful in developing targeted therapies for DFU.

Abstract

Complex fractures present significant challenges in orthopaedic surgery, particularly in terms of postoperative wound healing. Nutritional status plays a crucial role in the recovery process, with early nutritional support potentially influencing wound healing outcomes. This meta-analysis aimed to assess the impact of early nutritional interventions on postoperative wound healing and scar formation in patients with complex fractures. From an initial pool of 1742 articles, 7 studies were selected for analysis. The results revealed that preoperative nutritional support significantly improved early wound healing, as indicated by lower REEDA scores (SMD = −14.06, 95% CI: [−16.79, −11.32], p < 0.01) 1 week post-surgery. Furthermore, there was a notable reduction in scar formation, as demonstrated by lower Manchester Scar Scale scores (SMD = −25.03, 95% CI: [−30.32, −19.74], p < 0.01) 3 months post-surgery. These findings highlight the importance of incorporating nutritional strategies into the management of complex fractures to optimize postoperative recovery.

Abstract

This study aims to investigate the role of anoikis-related genes in diabetic foot (DF) by utilizing bioinformatics analysis to identify key genes associated with anoikis in DF. We selected the GEO datasets GSE7014, GSE80178 and GSE68183 for the extraction and analysis of differentially expressed anoikis-related genes (DE-ARGs). GO analysis and KEGG analysis indicated that DE-ARGs in DF were primarily enriched in apoptosis, positive regulation of MAPK cascade, anoikis, focal adhesion and the PI3K-Akt signalling pathway. Based on the LASSO and SVM-RFE algorithms, we identified six characteristic genes. ROC curve analysis revealed that these six characteristic genes had an area under the curve (AUC) greater than 0.7, indicating good diagnostic efficacy. Expression analysis in the validation set revealed downregulation of CALR in DF, consistent with the training set results. GSEA results demonstrated that CALR was mainly enriched in blood vessel morphogenesis, endothelial cell migration, ECM-receptor interaction and focal adhesion. The HPA database revealed that CALR was moderately enriched in endothelial cells, and CALR was found to interact with 63 protein-coding genes. Functional analysis with DAVID suggested that CALR and associated genes were enriched in the phagosome component. CALR shows promise as a potential marker for the development and treatment of DF.

Shame in patients undergoing ureterostomy: A cross‐sectional survey

Por: Qin Li · Lin Zhuo · Ting Zhang — Marzo 8th 2024 at 01:54

Abstract

Shame has an important impact on the mental health and quality of life of patients. The shame in patients with ureterostomy after cystectomy remains unclear. This survey aimed to evaluate the status quo and influencing factors of shame in patients with ureterostomy after cystectomy, to provide support for the clinical care. Patients with ureterostomy after cystectomy treated in the wound stomy clinic of a third-class hospital from 1 June 2022 to 31 July 2023 were included. General data questionnaire and social impact scale (SIS) were used for data collection. Univariate and multiple linear regression analysis were performed to evaluate the influencing factors of shame in patients with ureterostomy after cystectomy. One hundred and sixty four patients with ureterostomy after cystectomy were included. The total score of shame in patients with ureterostomy was (60.75 ± 6.31), which was in the high level. Age (r = 0.442), home place (r = 0.427), per capita monthly household income (r = 0.605), self-care ability (r = 0.597) and complications of stoma (r = 0.542) were correlated with the SIS score in patients with ureterostomy after cystectomy (all p < 0.05). Multiple linear regression analyses indicated that age, home place, per capita monthly household income, self-care ability and complications of stoma were the influencing factors of SIS score in patients with ureterostomy after cystectomy (all p < 0.05). The five variables explained 64.5% of the patients' sense of shame variation. Patients with ureterostomy after cystectomy have a serious sense of shame in the early stage after operation and there are many influencing factors. Health care providers should take early nursing interventions targeted on those influencing factors to reduce the patients' sense of shame.
