Abstract

Background

Diabetic cutaneous ulcers often pose considerable challenges in the healing process. These challenges stem from factors including inadequate perfusion of the ulcer's surrounding environment, persistent inflammation, tissue damage and microbial proliferation. The existing standard treatment modalities prove insufficient in fully addressing the complex pathogenesis of these ulcers. As a novel approach, researchers are exploring cellular therapies employing mesenchymal stem cells (MSCs) for the treatment of diabetic skin ulcers. MSCs are readily found in various tissues, including bone marrow, adipose tissue, placenta, amniotic membrane, amniotic fluid and umbilical cord. However, the optimal source of MSCs for effectively treating diabetic skin ulcers remains a topic of ongoing discussion.

Methods

We conducted a comprehensive search of Embase, PubMed and Web of Science databases, spanning from their inception to November 2022. Subsequently, we rigorously screened the literature following predetermined inclusion and exclusion criteria and evaluated the quality of the selected studies using the SYRCLE scale. Finally, the included literature underwent analysis, employing the Bayesian school of thought-based R language. To ensure transparency and accountability, we registered this study with PROSPERO's International Systematic Review Prospective Registry, with the Registration ID: CRD42023387421.

Results

We included a total of 11 articles in our analysis, all of which were randomized controlled studies involving 218 animal models. Among these studies, two utilized adipose-derived MSCs, six employed bone marrow-derived MSCs, one utilized amniotic membrane-derived MSCs and three utilized umbilical cord-derived MSCs. Our network meta-analysis results revealed that there were no statistically significant differences in the healing rates of diabetic skin ulcers among MSCs derived from amniotic membrane, adipose tissue, umbilical cord and bone marrow on days 7–8, 10–12 and 12–14. Notably, according to the probability ranking table, the most effective treatment for diabetic wounds was found to be amniotic membrane-derived MSCs.

Conclusion

There was no statistically significant difference in the efficacy of MSCs derived from amniotic membrane, adipose, umbilical cord and bone marrow in the treatment of diabetic skin ulcers during the short-term observation period, and the probability ranking graphs indicate that amniotic membrane-derived MSCs may be the best choice for the treatment of diabetic skin ulcers.

Association between asymptomatic hyperuricemia and risk of arthritis, findings from a US National Survey 2007-2018

Por: Liang · Z. · WU · D. · Zhang · H. · Gu · J. — Febrero 13th 2024 at 01:46
Background

Arthritis is thought to be closely related to serum uric acid. The study aims to assess the association between asymptomatic hyperuricemia (AH) and arthritis.

Methods

A multistage, stratified cluster was used to conduct a cross-sectional study of adult US civilians aged≥20 years from the 2007–2018 National Health and Nutrition Examination Survey. Participants with hyperuricemia and without hyperuricemia prior to gout were included. A questionnaire was used to determine whether participants had arthritis and the type of arthritis. Logistic regression was used to investigate the association between hyperuricemia and arthritis.

Result

During the past 12 years, the percentage of participants with arthritis changed from 25.95% (22.53%–29.36%) to 25.53% (21.62%–29.44%). The prevalence of osteoarthritis (OA) increased from 8.70% (95% CI: 6.56% to 10.85%) to 12.44% (95% CI: 9.32% to 15.55%), the prevalence of AH changed from 16.35% (95% CI: 14.01% to 18.40%) to 16.39% (95% CI: 13.47% to 19.30%). Participants with AH were associated with onset of arthritis (OR=1.34, 95% CI: 1.07 to 1.69), but the association was muted after adjusting demographic and socioeconomic factors. For participants aged 40–49 years, AH is associated with incident arthritis (OR=1.96, 95% CI: 1.23 to 2.99) and the relationship remained after adjusting for education level, income to poverty ratio, body mass index, diabetes, hypertension and smoking (OR=2.00, 95% CI: 1.94 to 3.36). Compared with male, female participants with AH are more likely to develop arthritis, especially in OA (OR=1.35, 95% CI: 1.14 to 1.60).

Conclusion

Our data identified AH as the risk factor for incident arthritis, especially for OA, which might be exaggerated in aged population and female population.

Role of HDL cholesterol in anthracycline-induced subclinical cardiotoxicity: a prospective observational study in patients with diffuse large B-cell lymphoma treated with R-CHOP

Por: Ou · W. · Jiang · T. · Zhang · N. · Lu · K. · Weng · Y. · Zhou · X. · Wang · D. · Dong · Q. · Tang · X. — Febrero 10th 2024 at 11:42
Objectives

Anthracycline-induced cardiotoxicity is a debilitating cardiac dysfunction for which there are no effective treatments, making early prevention of anthracycline-induced subclinical cardiotoxicity (AISC) crucial. High-density lipoprotein cholesterol (HDL-C) plays a role in cardioprotection, but its impact on AISC remains unclear. Our study aims to elucidate the protective capacity of HDL-C in AISC in patients with diffuse large B-cell lymphoma (DLBCL) treated with R-CHOP (cyclophosphamide, vincristine, doxorubicin, prednisone and rituximab).

Design

Prospective observational study.

Setting

Conducted in China from September 2020 to September 2022.

Participants

70 chemotherapy-naïve patients newly diagnosed with DLBCL who were scheduled to receive the standard dose of R-CHOP; 60 participants included in a case–control study (DOI: 10.1186/s12885-022-10085-6).

Primary outcome measures

Serum biomarkers, 2D speckle tracking echocardiography and conventional echocardiography were measured at baseline, at the end of the third and sixth cycles of R-CHOP and 6 and 12 months after chemotherapy.

Results

24 patients experienced AISC, while 10 did not. 36 patients were lost to follow-up and death. Cox regression analysis showed that higher levels of HDL-C were associated with a significantly lower risk of AISC (unadjusted HR=0.24, 95% CI 0.09 to 0.67, p=0.006; adjusted HR=0.27, 95% CI 0.09 to 0.79, p=0.017). Patients without AISC had a more stable and higher HDL-C level during the follow-up period. HDL-C levels significantly decreased from the end of the third cycle of chemotherapy to the end of the sixth cycle of chemotherapy in all patients (p=0.034), and particularly in the AISC group (p=0.003). The highest level of HDL-C was significantly higher in patients without AISC than in those with AISC (1.52±0.49 vs 1.22±0.29, p=0.034).

Conclusions

Our study suggests that higher HDL-C levels may associate with lower AISC risk in patients with DLBCL treated with R-CHOP. HDL-C could be a cardioprotective target, but further research is needed to confirm its benefits and limitations.

Por: Gong · Z. · Gao · Y. · Liu · W. · Liu · X. · Chen · Q. · Zhang · S. · Liu · L. · Li · J. · Li · W. — Febrero 9th 2024 at 02:19
Introduction

Neck pain is a common problem that severely affects physical and mental health. While musculoskeletal manipulations are recommended as the first-line treatment for adults with neck pain, the comparative effectiveness of different musculoskeletal manipulations remains unclear. This systematic review and network meta-analysis of randomised controlled trials (RCTs) will compare the effectiveness of different types of musculoskeletal manipulations, with the overarching aim of guiding clinical practice.

Methods and analysis

Two independent reviewers will search four English electronic databases (Web of Science, Cochrane Library, EMBASE, PubMed) and three Chinese electronic databases (China National Knowledge Infrastructure, China Science and Technology Journal Database, Wanfang) for relevant RCTs published from 1 January 2013 to 30 April 2023. The Clinical Trials Registry (ClinicalTrials.gov) will be searched for completed but unpublished RCTs. English and Chinese will be used to search English databases and Chinese databases, respectively. RCTs of musculoskeletal manipulations for adults (aged ≥18 years) with neck pain will be considered eligible for inclusion. A pairwise meta-analysis and network meta-analysis will be performed, and pooled risk ratios, standardised mean differences and 95% CIs will be determined.

Ethics and dissemination

Ethics approval is not required as this study is a literature review. The results of this review will be published in peer-reviewed journals or disseminated at conferences.

Por: Chen · X. · Yuan · J. · Zhao · W. · Qin · W. · Gao · J. · Zhang · Y. — Febrero 8th 2024 at 03:36
Objective

This study aimed to examine the differential magnitude of associations between specific dimensions of patient experience and overall patient satisfaction.

Design

A descriptive, cross-sectional design was used to collect patient experience and overall satisfaction data.

Setting

Participants were recruited at one tertiary general hospital, one tertiary specialised hospital, and one secondary hospital in Shanghai, China. These three institutes represent the main kinds of hospitals in the Chinese healthcare system.

Participants

1532 inpatients were recruited, and 1469 were included. The inclusion criteria were as follows: (1) having received inpatient service for at least 2 days; (2) able to understand the questions in the questionnaires; and (3) aged>18 years old. Patients who had impaired cognitive function and completed the questionnaires with missing information were excluded.

Primary and secondary outcome measure

Patient experience was measured using the Inpatient Experience with Nursing Care Scale, which is widely used in the China. The overall patient satisfaction was measured with 10-point response option.

Results

The LASSO (least absolute shrinkage and selection operator) regression results showed that as the penalty factor () = 0.0162, age, marriage status, financial status, length of hospital stay and numbers of previous of hospitalisation and six dimensions of nursing care remained in the model. As increases to 0.1862, only four patient experience variables, potentially the most influential on patient satisfaction, remained in the model. Patient experience with emotional support was the most significant dimension explaining patient satisfaction (β=0.1564), the second most significant dimension was admission and discharge management (β=0.1562), and the third was monitoring and coping with the progress of diseases (β=0.0613).

Conclusion

Patient experience with emotional support, admission and discharge management, monitoring and coping with the progress of diseases, and information and education are the most significant dimensions explaining patient satisfaction.

Sexual orientation and gender identity measures and viral suppression for people living with HIV: a protocol for a population-based cohort study

Por: Yang · X. · Olatosi · B. · Weissman · S. · Li · X. · Zhang · J. — Febrero 8th 2024 at 03:36
Introduction

The measure of sexual orientation and gender identity (SOGI) data in electronic health records (EHR) has been critical for addressing health disparities and inequalities, especially for HIV care. Given that gender and sexual minorities (eg, transgender, men who have sex with men and intersex) are key groups in people living with HIV (PLWH), SOGI data can facilitate a more accurate understanding about the HIV outcomes (eg, viral suppression) among this key group and then lead to tailored therapeutic services. The two-step SOGI collection method as an emerging gender measurement can be used to measure SOGI status in medical settings. Using the statewide cohort of PLWH in South Carolina (SC), this project aims to: (1) integrate statewide PLWH cohort data with their birth certificate data to evaluate SOGI measurements from multiple EHR sources; and (2) examine differences in viral suppression based on SOGI measurements.

Methods and analysis

Our EHR database includes several HIV data sources with patients’ gender information, such as SC Department of Health and Environmental Control Centre (DHEC), Health Sciences South Carolina (HSSC) and Prisma as well as birth certificate data to retrieve the sex at birth. The SC Enhanced HIV/AIDS Reporting System (e-HARS) from DHEC will provide longitudinal viral load information to define a variety of viral suppression status. Datasources like the SC office of Revenue and Fiscal Affairs (RFA) will extract longitudinal EHR clinical data of all PLWH in SC from multiple health systems; obtain data from other state agencies and link the patient-level data with county-level data from multiple publicly available data sources.

Ethics and dissemination

The study was approved by the Institutional Review Board at the University of South Carolina (Pro00129906) as a Non-Human Subject study. The study’s findings will be published in peer-reviewed journals and disseminated at national and international conferences and through social media.

Association between perioperative glucose profiles assessed by the continuous glucose monitoring (CGM) system and prognosis in patients with ST-segment elevation myocardial infarction (STEMI): protocol for a cohort study

Por: Shi · J. · Wang · X. · Zhang · H. · Ding · Y. · Wu · J. · Luo · S. · Hu · H. · Zheng · X. — Febrero 6th 2024 at 02:59
Introduction

ST-segment elevation myocardial infarction (STEMI) presents a serious cardiovascular condition requiring prompt intervention. Dysglycaemia has been identified as a significant risk factor impacting STEMI prognosis. However, limited research has focused on comprehensively examining the association between glucose dynamics during the perioperative period and patient outcomes. This study aims to address this gap by leveraging continuous glucose monitoring (CGM) technology to gain real-time insights into glucose fluctuations and their potential impact on STEMI prognosis.

Methods and analysis

This is a multicentre, prospective, 3-year follow-up cohort study. Between May 2023 and May 2024, 550 eligible STEM patients who underwent percutaneous coronary intervention are expected to be recruited. Using the CGM system, continuous glucose levels will be collected throughout the perioperative phase. Key clinical parameters, including cardiac biomarkers, angiographic findings and major adverse cardiovascular events, will be assessed in relation to glucose profile.

Ethics and dissemination

The study was approved by the Medical Research Ethics Committee of The First Affiliated Hospital of University of Science and Technology of China and will be conducted in accordance with the moral, ethical and scientific principles of the Declaration of Helsinki. Written informed consent will be obtained from all participants before any study-related procedures are implemented. Study results will be disseminated through conferences and peer-reviewed scientific journals.

Association of Long COVID with mental health disorders: a retrospective cohort study using real-world data from the USA

Por: Zhang · Y. · Chinchilli · V. M. · Ssentongo · P. · Ba · D. M. — Febrero 3rd 2024 at 14:48
Objectives

Mental health disorders (MHD) rank third for US adult hospitalisations. Given the substantial prevalence of ‘Long COVID’ in SARS-CoV-2 survivors, this study aims to assess its association with increased MHD risk using extensive real-world data.

Design

A retrospective cohort study with propensity score matching was conducted. We used the International Classification of Diseases, 10th Revision codes to identify individuals with Long COVID status and COVID-19 histories. Multivariable stratified Cox proportional hazards regression analysis was conducted to determine the association of Long COVID status with MHD.

Setting

Data were sourced from the TriNetX database, spanning records from 1 October 2021 to 16 April 2023.

Participants

Two distinct cohorts were established: one comprising individuals diagnosed with Long COVID and another comprising individuals with no history of Long COVID or COVID-19. At the start of the study, none of the participants had a recorded MHD.

Primary and secondary outcome measures

The main outcome of interest was a composite diagnosis of MHD. Secondary outcomes were individual mental health conditions.

Results

The study included 43 060 control participants without Long COVID and 4306 Long COVID participants, demonstrating well-balanced distribution across all covariates. After adjusting for 4 demographic factors and 10 comorbidities, Long COVID was associated with MHD (adjusted HR, aHR 2.60; 95% CI 2.37 to 2.85). In subgroup analysis, Long COVID was associated with major depression disorder (aHR 3.36; 95% CI 2.82 to 4.00) and generalised anxiety disorder (aHR 3.44; 95% CI 2.99 to 3.96).

Conclusions

In this retrospective large real-world cohort study, Long COVID was associated with an increased risk of incident MHD. The MHD impact is significant considering the vast number of patients with Long COVID. Enhanced MHD screening among COVID-19 survivors should be a priority.

Priming transcranial direct current stimulation for improving hemiparetic upper limb in patients with subacute stroke: study protocol for a randomised controlled trial

Por: Zhu · F. · Xu · X. · Jin · M. · Chen · J. · Feng · X. · Wang · J. · Yu · D. · Wang · R. · Lian · Y. · Huai · B. · Lou · X. · Shi · X. · He · T. · Lu · J. · Zhang · J. J. · Bai · Z. — Febrero 3rd 2024 at 05:51
Introduction

Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique that modulates brain states by applying a weak electrical current to the brain cortex. Several studies have shown that anodal stimulation of the ipsilesional primary motor cortex (M1) may promote motor recovery of the affected upper limb in patients with stroke; however, a high-level clinical recommendation cannot be drawn in view of inconsistent findings. A priming brain stimulation protocol has been proposed to induce stable modulatory effects, in which an inhibitory stimulation is applied prior to excitatory stimulation to a brain area. Our recent work showed that priming theta burst magnetic stimulation demonstrated superior effects in improving upper limb motor function and neurophysiological outcomes. However, it remains unknown whether pairing a session of cathodal tDCS with a session of anodal tDCS will also capitalise on its therapeutic effects.

Methods and analysis

This will be a two-arm double-blind randomised controlled trial involving 134 patients 1–6 months after stroke onset. Eligible participants will be randomly allocated to receive 10 sessions of priming tDCS+robotic training, or 10 sessions of non-priming tDCS+robotic training for 2 weeks. The primary outcome is the Fugl-Meyer Assessment-upper extremity, and the secondary outcomes are the Wolf Motor Function Test and Modified Barthel Index. The motor-evoked potentials, regional oxyhaemoglobin level and resting-state functional connectivity between the bilateral M1 will be acquired and analysed to investigate the effects of priming tDCS on neuroplasticity.

Ethics and dissemination

The study has been approved by the Research Ethics Committee of the Shanghai Yangzhi Rehabilitation Center (reference number: Yangzhi2023-022) and will be conducted in accordance with the Declaration of Helsinki of 1964, as revised in 2013.

Study protocol of short-course radiotherapy combined with CAPOX and PD-1 inhibitor for locally advanced colon cancer: a randomised, prospective, multicentre, phase II trial (TORCH-C)

Por: Zhang · H. · Li · Y. · Xia · F. · Sun · Y. · Shen · L. · Wan · J. · Chen · Y. · Wang · Y. · Zhou · M. · Wu · R. · Zhou · S. · Wang · Y. · Liu · F. · Cai · S. · Zhang · Z. — Febrero 3rd 2024 at 05:51
Introduction

The preliminary result of the TORCH trial has shown a promising complete response (CR) for managing locally advanced rectal cancer with neoadjuvant short-course radiotherapy (SCRT) combined with chemotherapy and PD-1 inhibitor. For locally advanced colon cancer (LACC) with bulky nodal disease and/or clinically T4, neoadjuvant chemotherapy followed by colectomy with en bloc removal of regional lymph nodes is the suggested treatment. However, the CR rate is less than 5%. TORCH-C will aim to investigate neoadjuvant SCRT combined with chemotherapy and PD-1 inhibitor in LACC.

Methods and analysis

TORCH-C is a randomised, prospective, multicentre, double-arm, open, phase II trial of SCRT combined with chemotherapy and immunotherapy in LACC with microsatellite stable (MSS) patients and cT4 or bulky nodes. Eligible patients will be identified by the multidisciplinary team. 120 patients will be randomised 1:1 to the intervention or control arm. The patients in the control arm will receive four cycles of capecitabine plus oxaliplatin (CAPOX). The patients in the intervention arm will receive SCRT, followed by four cycles of CAPOX and PD-1 inhibitor (serplulimab). Both arms will receive curative surgery, followed by four cycles of CAPOX. The primary endpoint is pathological complete regression.

TORCH-C (TORCH-colon) trial aims to investigate whether the combination of immunotherapy and chemoradiotherapy improves the treatment effect in LACC with MSS. TORCH-C will establish the TORCH platform, a key part of our long-term strategy to develop neoadjuvant treatment for colorectal cancer.

Best practices for managing malodorous and infected wounds in advanced cervical cancer

Abstract

This cross-sectional study was conducted to examine the most effective strategies for managing malodorous and infected wounds in patients who have been diagnosed with advanced cervical cancer. The research was conducted in Liupanshui, China. The study specifically examined demographic profiles, wound characteristics and effectiveness of wound management approaches. The study incorporated the heterogeneous sample of 289 participants who fulfilled the inclusion criteria. Data collection was conducted via structured questionnaires and medical record evaluations. Descriptive statistics and statistical analyses, such as regression analysis, were utilized to evaluate demographic attributes, wound profiles and effects of different approaches to wound management. The findings unveiled the heterogeneous demographic composition of patients, encompassing differences in socioeconomic standing, educational attainment and age. A wide range of wound characteristics were observed, as 65.7% of lesions during the acute phase with diameter between 2 and 5 centimetres, while 41.5% of lesions had this range. The most prevalent types of infections were those caused by fungi (48.4%), followed by bacterial infections lacking resistance (38.1%). A moderate degree of odour intensity was prevalent, affecting 45.0% of the cases. With maximal odour reduction of 80%, a mean healing time of 25 days and patient satisfaction rating of 4.5 out of 5, Negative Pressure Wound Therapy demonstrated itself to be the most efficacious treatment method. Additional approaches, such as photodynamic therapy and topical antibiotic therapy, demonstrated significant effectiveness, as evidenced by odour reductions of 70% and 75%, respectively, and patient satisfaction ratings of 4.3 and 4.2. Thus, the study determined challenges associated with management of malodorous and infected lesions among patients with advanced cervical cancer. The results underscored the significance of individualized care approaches, drew attention to efficacious wound management techniques and identified critical determinants that impacted patient recuperation. The findings of this study hold potential for advancing palliative care for individuals diagnosed with advanced cervical cancer.

Incidence and Management of Skin Lesions and Minor Wounds in Chronic Obstructive Pulmonary Disease Patients undergoing Advanced Bronchodilator Therapy

Por: Caiwen Shi · Ming Zhang — Febrero 2nd 2024 at 01:04

Abstract

While triple inhalation therapy is commonly employed in the treatment of chronic obstructive pulmonary disease (COPD), limited knowledge exists regarding its impact on the healing of minor wounds and integrity of the epidermis. This study investigated the impact of combining triple inhalation therapy with double bronchodilators on the aforementioned parameters in patients with stable COPD. A cross-sectional study was conducted in Changzhou, China, from March 2022 to October 2023, involving 540 patients who had received the diagnosis of stable COPD. Combined therapy participation requirements stipulated a minimum of 6 months of uninterrupted treatment. Dermatological examinations, demographic data and clinical records were utilized to collect information regarding the elasticity, moisture content and duration of wound healing. The research revealed that there were no statistically significant differences in demographic and clinical characteristics between the groups that received triple inhalation alone and triple inhalation in combination with double bronchodilators (p > 0.05). Nevertheless, the combined therapy group demonstrated shorter duration since receiving a diagnosis of COPD (p < 0.05). It is noteworthy to remark that the combined therapy group exhibited significantly higher skin moisture content and shorter interval for wound recovery when compared with the group that only received triple inhalation (p < 0.05). Lung function measurements in combined therapy group indicated enhanced Forced expiratory volume in the first second (FEV1) and FEV1/forced vital capacity ratio, as well as a reduction in COPD exacerbations. Nevertheless, no statistically significant distinction in skin elasticity was observed among the groups (p > 0.05). The supplementary application of triple inhalation therapy and double bronchodilators in stable COPD patients not only improved respiratory outcomes but also positively impacted skin health, specifically by promoting wound healing and augmenting moisture levels. These results highlighted the possible benefits of implementing a holistic treatment approach in COPD, suggesting that incorporating these therapies could offer additional advantages to the epidermis.

Effect of transconjunctival sutureless vitrectomy versus 20‐G vitrectomy on surgical wound closure in patients: A meta‐analysis

Por: Yan Huang · Jun Sun · Jimin Wang · Xuedong Zhang · Zhongpei Chen — Febrero 2nd 2024 at 00:44

Abstract

A meta-analysis was conducted to evaluate the impact of transconjunctival sutureless vitrectomy (TSV) over 20 G vitrectomy on wound healing, as well as the requirements for closing the wound in order to treat vitreoretinal diseases. Among the 500 cases who had been treated with vitrectomy to September 2023, 250 were treated by transconjunctiva without vitrectomy and 250 were treated with 20 G vitrectomy. The odds ratio (OR) and mean difference (MD) of 95% confidence interval (CI) were computed to evaluate the influence of wound opening and closing on vitrectomy diseases. The evaluation of vitreoretinal diseases was performed with either a random-or fixed-effect model, which involved TSV compared to 20 G vitrectomy. Compared to 20 G vitrectomy, the opening time of the wound in TSV was less (MD, −2.03; 95% CI, −2.87, −1.19; p < 0.0001); Compared to 20 G vitrectomy, the closing time of the wound was less (MD, −4.84; 95% CI, −6.38, −3.03; p < 0.0001); Nevertheless, there were no statistically significant differences in the incidence of vitreous haemorrhage after TSV surgery compared with 20 G vitrectomy (OR, 0.74; 95% CI, 0.25, 2.18; p = 0.59). TSV vitrectomy can shorten the duration of the operation and speed up the healing of the wound. It is suggested that additional studies be carried out with a larger sample size in order to verify this conclusion.

Impact of evidence‐based nursing on surgical site wound infection after caesarean: A meta‐analysis

Por: Li‐Hua Zhang · Jian‐Li Wu · Qin Zhang · Nai‐Mei Li · Wen‐Ying Li — Febrero 1st 2024 at 12:24

Abstract

We conducted this study to investigate the effect of evidence-based care on surgical site wound infection after caesarean section. A computerised search of PubMed, Embase, Google Scholar, Cochrane Library, China National Knowledge Infrastructure and Wanfang databases for randomised controlled trials (RCTs) on the use of evidence-based care in caesarean section delivery was applied from the database inception to November 2023. Two researchers independently screened the literature, extracted data and performed quality assessment based on inclusion and exclusion criteria. Stata 17.0 software was applied for data analysis. Twenty-one RCTs involving 3269 caesarean sections were finally included. The analysis revealed the implementation of evidence-based nursing interventions was effective in reducing the incidence of post-caesarean section wound infections (OR = 0.29, 95% CI: 0.21–0.39, p < 0.001) and complications (OR = 0.29, 95% CI: 0.23–0.38, p < 0.001) compared with conventional care. This study shows that the application of evidence-based nursing in postoperative caesarean section care can effectively reduce the incidence of postoperative wound infection and complications and improve the quality of life, which is worthy of clinical nursing application and promotion.

Introduction

Previous studies suggested that electrical impedance tomography (EIT) has the potential to guide positive end-expiratory pressure (PEEP) titration via quantifying the alveolar collapse and overdistension. The aim of this trial is to compare the effect of EIT-guided PEEP and acute respiratory distress syndrome (ARDS) network low PEEP/fraction of inspired oxygen (FiO2) table strategy on mortality and other clinical outcomes in patients with ARDS.

Methods

This is a parallel, two-arm, multicentre, randomised, controlled trial, conducted in China. All patients with ARDS under mechanical ventilation admitted to the intensive care unit will be screened for eligibility. The enrolled patients are stratified by the aetiology (pulmonary/extrapulmonary) and partial pressure of arterial oxygen/FiO2 (≥150 mm Hg or 2 table proposed by the ARDS Network. The primary outcome is 28-day survival.

Analysis

Qualitative data will be analysed using the 2 test or Fisher’s exact test, quantitative data will be analysed using independent samples t-test or Mann-Whitney U test. Kaplan-Meier analysis with log-rank test will be used to evaluate the 28-day survival rate between two groups. All outcomes will be analysed based on the intention-to-treat principle.

Ethics and dissemination

The trial is approved by the Institutional Research and Ethics Committee of the Peking Union Medical College Hospital. Data will be published in peer-reviewed journals.

Trial registration number

NCT05307913.

Effects of different dressings in the prevention of facial skin pressure injury related to non‐invasive ventilation: Systematic review and network meta‐analysis

Por: Guoli Zhang · Fanghong Yan · Ruiyi Sun · Guotian Peng · Juhong Pei · Hongyan Zhang · Yuxia Ma · Lin Han — Febrero 1st 2024 at 07:13

Abstract

To investigate the preventive effect of different dressings on pressure injuries related to non-invasive ventilation equipment and to screen the efficacy of dressings. Systematic review and network meta-analysis. PubMed, the Cochrane Library, Web of Science, EMBASE, Cumulative Index to Nursing & Allied Health Literature (CINAHL), China Knowledge Resource Integrated Database (CNKI), Wanfang Database, Chinese Biomedical Database (CBM) and Weipu Database (VIP) were used for the search from the date of inception of each database to 15 October 2023. The quality of the data was assessed using the Cochrane Risk of Bias tool. Stata 16.0 Software was used to analysis and ranking of different types of dressings. A total of 23 randomized controlled trials on 7 interventions were included in the final analysis. The effectiveness of these in preventing the overall incidence of pressure injuries is ranked from best to worst as follows: hydrogel dressing > foam dressing > petroleum jelly gauze dressing > hydrocolloid dressing > film dressing > clean gauze dressing > sterile gauze. Sixteen studies reported the incidence of Stage I pressure injuries, the effectiveness in preventing the incidence of Stage I pressure injuries was ranked from best to least effective: foam dressing > hydrogel dressing > petroleum jelly gauze dressing > hydrocolloid dressing > film dressing > clean gauze dressing > sterile gauze dressing. Fourteen studies reported the incidence of Stages I/II pressure injuries, the effective in preventing the incidence of Stages I and II pressure injuries was ranked from best to least effective: foam dressing > hydrogel dressing > petroleum jelly gauze dressing > hydrocolloid dressing > clean gauze dressing > sterile gauze dressing. Considering the advantages and disadvantages of different dressings, both hydrogel and foam dressings are effective in preventing pressure injuries related to non-invasive ventilation equipment.

Abstract

In this study, we explored the use of thermal imaging technology combined with computer vision techniques for assessing surgical incision healing. We processed 1189 thermal images, annotated by experts to define incision boundaries and healing statuses. Using these images, we developed a machine learning model based on YOLOV8, which automates the recognition of incision areas, lesion segmentation and healing classification. The dataset was divided into training, testing and validation sets in a 7:2:1 ratio. Our results show high accuracy rates in incision location recognition, lesion segmentation and healing classification, indicating the model's effectiveness as a precise and automated diagnostic tool for surgical incision healing assessment. Conclusively, our thermal image-based machine learning model demonstrates excellent performance in wound assessment, paving the way for its clinical application in intelligent and standardized wound management.
