A systematic review and meta-analysis of chronic obstructive pulmonary disease in asia: risk factors for readmission and readmission rate.

BACKGROUND: Patients with chronic obstructive pulmonary disease (COPD) often require hospital readmission because of exacerbation of their condition. These frequent exacerbations reduce quality of life, work performance, and emotional health. However, few studies have investigated the risk factors for readmission and readmission rates in Asian patients with COPD. We conducted a systematic review to identify and understand the major risk factors for readmission in patients with COPD in Asia and the readmission rate. METHOD: We searched PubMed, MEDLINE, Embase, China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, and China Biomedical Literature Database from database inception to September 2023 to identify studies on the readmission rate and risk factors for COPD in Asian patients. Chinese search terms included "COPD," "chronic obstructive pulmonary disease," "risk factors," "recurrence," "readmission," and "acute exacerbation." English search terms included "chronic obstructive pulmonary disease," "COPD," "lung emphysema," "hospital admission," "patient readmission," and "readmission." We extracted first author, publication year, research area, sample size, sex, risk factors, and readmission rates. The included studies' quality was evaluated using the Agency of Healthcare Research and Quality. Meta-synthesis was conducted on readmission rates and risk factors for readmission. Subgroups were formed by age, research area, sample size, and research type, and meta-regression analysis was conducted on the 30-day, 90-day, and 365-day readmission rates of patients to determine the source of heterogeneity. Finally, the results' robustness was evaluated using sensitivity analysis. Begg and Egger tests were used to evaluate publication bias. RESULTS: Meta-analysis of 44 studies, with 169,255 participants, indicated that risk factors for COPD readmission in Asia included: history of multiple hospital admissions, ≥ 3 comorbidities, male sex, ratio of eosinophils percentage ≥ 2%, body mass index < 18.5, smoking history, pulmonary heart disease comorbidity, COPD assessment test score > 20, nutritional disorder, Neutrophil-to-Lymphocyte ratio > 7, and FEV1 < 50. The 30-, 90-, and 365-day readmission rates of patients were 19%, 31%, and 42%, respectively. CONCLUSIONS: Patients with COPD in Asia generally have high readmission rates and different risk factors. To reduce healthcare, economic, and social burdens, interventions should address major risk factors, early prevention, and screening.

Identifying the factors affecting financial toxicity status in patients with middle and advanced colorectal cancer: a cross-sectional study.

Background: Colorectal cancer (CRC) ranks as the second most prevalent type of cancer in China. The financial implications of treatment are a significant factor to be taken into account for patients diagnosed with middle and advanced stages of colorectal cancer (III-IV CRC). The research aims to explore current financial toxicity (FT) conditions and analyze factors that may influence it in patients with middle and advanced CRC. Method: This is a cross-sectional survey. The participants of the study were individuals diagnosed with middle and advanced colorectal cancer who were admitted to the hospital between January and June 2023. The cross-sectional survey utilized a variety of instruments, including a general information questionnaire, a cancer patient report outcome economic toxicity scale, a medical coping style questionnaire, an Anderson symptom assessment scale, a disease shame scale, and a social support scale. Multiple linear regression analysis was employed to examine the factors influencing FT. Result: A cohort of 264 patients diagnosed with stage III-IV CRC were included in the study. The majority of patients with intermediate and advanced CRC (87.1%, n = 230) reported experiencing substantial financial strain. Multivariate analysis revealed that factors influencing FT included low family monthly income, out-of-pocket expenses, unemployment, undergoing surgical treatment, the level of stigma, and the severity of symptoms (P < 0.001). Conclusion: Patients with stage III-IV cancer (CRC) demonstrate increased levels of financial toxicity (FT), a common occurrence in individuals with moderate to severe CRC. In patients with stage III-IV CRC, the presence of FT is correlated with various factors including family monthly income, medical payment methods, work status, surgical treatment, stigma levels, and symptom severity. These characteristics may serve as influencing factors for subsequent treatment decisions.

Reduced Radial Artery Occlusion in Transradial Cerebral Angiography: Key Predictive Factors and Preventive Measures from a Single-Center Study of 543 Patients.

BACKGROUND The transradial approach (TRA) for cerebral angiography and neurointerventional treatment has gained popularity, but the narrow diameter and weak pulsation of the radial artery lower the initial puncture success rate compared to femoral artery puncture. This retrospective study from a single center evaluated the incidence of and factors associated with radial artery occlusion (RAO) in 543 patients who underwent transradial approach (TRA) for cerebral angiography. MATERIAL AND METHODS We included 543 patients who underwent TRA from July 2021 to February 2024. Ultrasound was used to determine whether the radial artery was occluded. Relevant clinical data were recorded to assess the incidence of and factors affecting RAO. RESULTS At 24 h after DSA, we performed ultrasound imaging. The patients were divided into an RAO group (n=32) and a non-RAO group (n=511). Results showed that RAO was significantly higher in patients who did not have add heparin to the antispasmodic agents, and they were more likely to have needed more than 3 radial artery puncture attempts, and tended to have received an 11-cm radial artery sheath with the Cordis puncture needles (all P<0.05). Multiple regression logistic analysis showed that adding heparin to the antispasmodic agents (OR=0.076, 95% CI: 0.018-0.321, P<0.001), having fewer than 3 radial artery puncture attempts (OR=0.245, 95% CI: 0.111-0.541, P<0.001), using a 16-cm radial artery sheath (OR=0.195, 95% CI: 0.067-0.564, P=0.003), and using Terumo puncture needles (OR=0.325, 95% CI: 0.148-0.717, P=0.005) can reduce the incidence of radial artery occlusion. CONCLUSIONS Our center found that adding heparin to the antispasmodic agents reduced the number of radial artery punctures attempts, and using a 16-cm radial artery sheath significantly lowered the incidence of early RAO after transradial cerebral angiography.

Psoralen attenuates cigarette smoke extract-induced inflammation by modulating CD8+ T lymphocyte recruitment and chemokines via the JAK2/STAT1 signaling pathway.

Chronic obstructive pulmonary disease (COPD) is a respiratory inflammatory disease. Psoralen (PSO) is the main pharmacological component identified from Bu-Shen-Fang-Chuan formula which has been traditionally used in treatment of COPD, yet its efficacy in COPD inflammation were unreported. In this study, we aimed to elucidate the anti-inflammatory potential of PSO in COPD and unravel the underlying mechanisms, focusing on T lymphocyte recruitment and the modulation of chemokines, namely monokine induced by interferon-gamma (CXCL9), interferon inducible protein 10 (CXCL10), and interferon inducible T-Cell alpha chemoattractant (CXCL11). In vitro, RAW264.7 was stimulated by interferon (IFN)-γ + cigarette smoke extract (CSE) and were treated with PSO (2.5, 5, 10 µM), then the levels of chemokines and the activation of Janus kinase (JAK)/Signal transducer and activator of transcription 1 (STAT1) pathway were analyzed by real time PCR and western blot. In vivo, a murine model was established by intraperitoneal injection of CSE on day 1, 8, 15, and 22, then treated with PSO (10 mg/kg). Our experiments in vitro illustrated that PSO reduced the levels of CXCL9, CXCL10, and CXCL11, and decreased the protein phosphorylation levels of JAK2 and STAT1. Additionally, PSO effectively improved inflammatory infiltration and decreased the proportion of CD8+ T cells in CSE-exposed mice. Furthermore, PSO reduced the levels of CXCL9, CXCL10, and CXCL11 in bronchoalveolar lavage fluid (BALF) and lung tissue, and decreased the protein phosphorylation levels of JAK2 and STAT1. In conclusion, our results revealed the therapeutic potential of PSO for COPD inflammation, possibly mediated through the regulation of CD8+ T cell recruitment and chemokines via the JAK2/STAT1 signaling pathway.

Mutual communication intervention for colorectal cancer patient-spousal caregiver dyads: A randomized controlled trial.

OBJECTIVE: Gender could impact the psychosocial outcomes and coping strategies of cancer patients and their spousal caregivers (SCs). This study aims to develop a gender-concerned program for colorectal cancer (CRC) couple-based mutual communication intervention (MCI) and to assess its effectiveness on the intra-couple relationship and the individual functions of the partners. DESIGN: A randomized clinical trial with two study groups was utilized. METHODS: A total of 144 CRC patients and their SCs were randomly assigned to either MCI or usual care (UC) groups, and all of them were required to complete the measurements at baseline and post-intervention. The primary outcome was for mutual communication, and the secondary outcomes included dyadic coping, relationship satisfaction, anxiety, depression, benefit finding and quality of life. The data were analysed by multi-level modelling. RESULTS: The MCI program was feasible and acceptable for Chinese CRC couples and was effective for the improvement of the intra-couple relationship and the individual functions of each partner. CRC patients showed more improvement in mutual communication and dyadic coping than their SCs in the MCI group. Also, this intervention effectiveness was found to be independent of gender. CONCLUSIONS: The MCI program is beneficial for Chinese CRC couple's adaptation outcomes. This suggests that clinical medical staff should consider the gender tendency during the implementation of interventions. More researches are needed to extend the application of the MCI program to different participants (e.g. patients with the diagnosis of other types of cancer and their SCs).

The Illness Perceptions and Coping Experiences of Patients with Colorectal Cancer and Their Spousal Caregivers: A Qualitative Study.

(1) Background: Illness perception (IP) is an important psychological construct for couples dealing with cancer, which impacts health outcomes and the psychological adjustment to cancer. More research is needed to explore the traits of IP and the efforts of couples coping with cancer. Thus, this study was designed to explore the coping experiences and features of the IPs of couples dealing with cancer. (2) Methods: A total of 24 patients with colorectal cancer (CRC) and 20 spousal caregivers (SCs) participated in semi-structured interviews. All interviews were recorded digitally, transcribed, and analyzed by using an inductive thematic analysis. (3) Results: Two themes (individualized and predominant IP; IP sharing and restructuring) were developed. A preliminary framework was formulated to illustrate the relations among subthemes and the relations between themes with an adjustment of a positive IP to CRC. In this framework, based on multiple sources and factors, the natural disparities formed the IPs of the partners of couples and determined the incongruence of IPs. The effects of IP incongruence on lives under the disease guided the three directions of coping approaches (i.e., information and available support, appropriate disclosure and reflection, and leaving the CRC diagnosis behind) which were adopted by couples dealing with CRC to share and restructure the IP with their spouses for effective dyadic coping. (4) Conclusions: This study provides insights to healthcare providers into the experiences of couples dealing with CRC and the development of couple-based IP intervention programs: (a) it initially provides adequate factual knowledge for enhancing beliefs in the ability to control illness, (b) encourages illness-centered conversations and disclosure regarding thoughts and emotions for promoting positive congruence of IP between the partners of couples dealing with a hard dilemma, and (c) guides couples to perceive positive changes and explore the illness's meaning. Understanding each theme of personalized IP and adopting effective IP coping approaches can help guide couples dealing with CRC to efficiently promote constructive IP and better health outcomes.

Factors Influencing Social Isolation among Cancer Patients: A Systematic Review.

(1) Background: Social isolation, which has numerous adverse effects on health status, is prevalent among cancer patients. This review proposes to identify the influencing factors of social isolation among cancer patients. (2) Methods: Articles published in English or Chinese from six electronic databases before December 2023 were identified via a systematic search. A manual search was also performed. (3) Results: Twenty-eight studies were identified in this systematic review. The factors associated with social isolation can be summarized into the following categories: demographic characteristics, having cancer, health status, coping, social support and social interaction. Despite the heterogeneity, 20 factors were significantly associated with social isolation, including age, gender, comorbidity burden, education level, residence, medical insurance, occupation status, personality, race, smoking status, having children, not living alone, household income level, marital status, the role of primary caregiver, physical health status, mental health status, social health status, coping styles, and the level of social support and social interaction. (4) Conclusions: The systematic review showed that cancer patients' social isolation was influenced by their demographic characteristics, cancer-related factors, physical condition, psychological status, social health status, coping styles, and level of social support and social interaction. In addition, future group intervention could be considered to improve social isolation.

Interventions strategies and their efficacy in illness perceptions in patients with cancer: A systematic review and meta-analysis.

PURPOSES: To identify intervention strategies for improving illness perception (IP) of cancer patients and/or family caregivers; and to examine the effects of IP interventions by meta-analysis. METHODS: A systematic search was performed to identify literature that focused on improving the IP of cancer patients and/or family caregivers from the establishment of eight databases to August 2023. Manual screening was also applied. The IP intervention strategies for cancer populations were synthesized basing the CSM. Meta-analysis was conducted to assess the effects of IP interventions on health outcomes. Multiple subgroup analyses of the same intervention conditions were conducted to explore the optimal IP-focused intervention. RESULTS: 18 studies were included. 11 studies were conducted in a meta-analysis. No studies on family caregivers' IP were identified. Compared to general care, subgroup analysis revealed that IP interventions had favorable effects on cancer patients' IP as well as quality of life and other outcomes. Six IP intervention strategies (information support, cognitive reframing, emotion adjustment, active coping, effective appraisal, and self-social identification) were generated. Meta-analysis showed that compared with theory-less studies (Z = 8.64, p < 0.01) and single delivery formats (Z = 3.66, p < 0.01), the theory-based interventions (Z = 10.86, p < 0.01) and mixed delivery formats (Z = 7.15, p < 0.01) had higher positive effects on IP outcomes. CONCLUSIONS: The positive outcomes of IP intervention focusing on cancer patients were highlighted. IP traits and patients' and their caregivers' needs in coping with specific cancer types should be explored before the intervention design. More IP interventions targeting cancer dyads are warranted to develop in the future.

A couple-based unmet supportive care needs intervention for colorectal cancer couples: A preliminary feasibility study.

PURPOSE: To support colorectal cancer couples cope with cancer, we developed a couple-based unmet supportive care needs intervention program guided by the Supportive Care Needs Framework and examined the feasibility, acceptability, and initial effects of the unmet supportive care needs program. METHODS: The design of a pre-and post-intervention study was conducted among Chinese colorectal cancer couples. The intervention was delivered in five sessions through in-person and telephone interventions combined. To measure program feasibility through recruitment and retention rates, and to test program acceptability through quantitative and qualitative post-intervention program assessments. The complete data (N = 20 pairs) were used to calculate effect sizes to assess the initial intervention effect. RESULTS: There was evidence of the feasibility of the intervention program in terms of recruitment (66.7%) and retention (83.3%) rates. Participants' satisfaction with the program also attested to its acceptability. The intervention (Cohen's = 0.15-0.56) had a small-moderate effect size in improving unmet supportive care needs and most cancer-adapted outcomes for colorectal cancer couples, validating the initial effect of the program. CONCLUSIONS: The unmet supportive care needs program is feasible, acceptable, and preliminarily effective in supporting Chinese colorectal cancer couples to improve unmet supportive care needs and cancer adaptability, as provided by this study.

A comprehensive study on machine learning models combining with oversampling for bronchopulmonary dysplasia-associated pulmonary hypertension in very preterm infants.

BACKGROUND: Bronchopulmonary dysplasia-associated pulmonary hypertension (BPD-PH) remains a devastating clinical complication seriously affecting the therapeutic outcome of preterm infants. Hence, early prevention and timely diagnosis prior to pathological change is the key to reducing morbidity and improving prognosis. Our primary objective is to utilize machine learning techniques to build predictive models that could accurately identify BPD infants at risk of developing PH. METHODS: The data utilized in this study were collected from neonatology departments of four tertiary-level hospitals in China. To address the issue of imbalanced data, oversampling algorithms synthetic minority over-sampling technique (SMOTE) was applied to improve the model. RESULTS: Seven hundred sixty one clinical records were collected in our study. Following data pre-processing and feature selection, 5 of the 46 features were used to build models, including duration of invasive respiratory support (day), the severity of BPD, ventilator-associated pneumonia, pulmonary hemorrhage, and early-onset PH. Four machine learning models were applied to predictive learning, and after comprehensive selection a model was ultimately selected. The model achieved 93.8% sensitivity, 85.0% accuracy, and 0.933 AUC. A score of the logistic regression formula greater than 0 was identified as a warning sign of BPD-PH. CONCLUSIONS: We comprehensively compared different machine learning models and ultimately obtained a good prognosis model which was sufficient to support pediatric clinicians to make early diagnosis and formulate a better treatment plan for pediatric patients with BPD-PH.

End-organ damage from neonatal invasive fungal infection: a 14-year retrospective study from a tertiary center in China.

BACKGROUND: Invasive fungal infection (IFI) has become an increasing problem in NICU neonates, and end-organ damage (EOD) from IFI is one of the leading causes of morbidity and mortality in neonates. This study was conducted to summarize clinical data on epidemiology, risk factors, causative pathogens, and clinical outcomes of IFI-associated EOD among neonates in a center in China for the sake of providing references for prevention and treatment of fungal infections in neonates in future. METHODS: The clinical data of IFI neonates who received treatment in a tertiary NICU of China from January 2009 to December 2022 were retrospectively analyzed, including causative pathogens and the incidence of EOD. The neonates were divided into EOD group and non-EOD (NEOD) group. The general characteristics, risk factors and clinical outcomes of the two groups were compared. RESULTS: Included in this study were 223 IFI neonates (137 male and 86 female) with a median gestational age (GA) of 30.71 (29,35) weeks and a median birth weight (BW) of 1470 (1120,2150) g. Of them, 79.4% were preterm infants and 50.2% were born at a GA of ≥ 28, <32 weeks, and 37.7% with BW of 1000-1499 g. Candida albicans (C. albicans) was the most common Candida spp. in these neonates, accounting for 41.3% of all cases, followed by C. parapsilosis (30.5%) and C. glabrata (7.2%). EOD occurred in 40 (17.9%) of the 223 cases. Fungal meningitis was the most common EOD, accounting for 13.5% of the 40 EOD cases. There was no significant difference in the premature birth rate, delivery mode, GA and BW between EOD and NEOD groups, but the proportion of male infants with EOD was higher than that without. There was no significant difference in antenatal corticosteroid use, endotracheal intubation, invasive procedures, use of antibiotics, total parenteral nutrition, blood transfusion, postnatal corticosteroid use, fungal prophylaxis and the incidence of necrotizing enterocolitis between the two groups, but the proportion of C. albicans infection cases in EOD group was higher than that in NEOD group (57.5% vs. 37.7%). Compared with NEOD group, the proportion of cured or improved infants in EOD group was significantly lower (P < 0.05), and the number of infants who died or withdrew from treatment was larger (P < 0.05). CONCLUSIONS: Our retrospective study showed that preterm infants were prone to fungal infection, especially very preterm infants. C. albicans was the most common Candida spp. for IFI, and was a high-risk factor for EOD. EOD can occur in both full-term and premature infants, so the possibility of EOD should be considered in all infants with IFI.

A Systematic Review of Cognitive Impairment in Individuals With Colorectal Cancer.

PROBLEM IDENTIFICATION: Patients with colorectal cancer (CRC) encounter varying degrees of objective and subjective cognitive impairment. The prevalence of objective and subjective cognitive impairment, factors affecting cognitive impairment, and interventions are presented in this review. LITERATURE SEARCH: The CINAHL Plus®, Cochrane Library, Embase®, PsycINFO®, PubMed®, and CNKI databases were systematically searched from the time of the database's establishment to May 2023. Manual searches for the relevant articles in the literature's references were also conducted. DATA EVALUATION: The results were independently assessed by two reviewers. SYNTHESIS: 25 studies were included. The prevalence of cognitive impairment in individuals with CRC was measured differently according to study designs. A model of factors contributing to cognitive impairment guided the integration of factors, including cancer treatments, psychosocial factors, and physical and emotional health conditions. Incorporated intervention programs could be integrated between objective and subjective aspects. Interventions relieved cognitive impairment in individuals with CRC. IMPLICATIONS FOR NURSING: The results of this review supported enhanced assessment and monitoring of cognitive impairment, particularly subjective cognitive impairment.

A couple-based dyadic coping intervention for colorectal cancer patient-spousal caregiver dyads: A randomized controlled study.

PURPOSE: To evaluate the clinical effects of a couple-focused dyadic coping intervention in colorectal cancer (CRC) couples. METHODS: The study was a single-blinded randomized controlled study which 226 CRC couples were recruited and randomized to either the intervention (N = 113) or the control (N = 113) group. All couples received usual care while the six-week dyadic coping intervention was provided to the intervened couples in psycho-education and skill training methods through face-to-face combined with telephone formats. Measurement data, including dyadic coping, marital satisfaction, quality of life and psychological well-being were collected at pre- and post-intervention periods. And multilevel model (MLM) was applied to analyze the effects of the intervention and the role tendency. RESULTS: A total of 173 couples completed the program and post-intervention evaluation. The retention rate was 76.5%. Results from MLM showed that the dyadic coping intervention is effective in promoting levels of dyadic coping (P < 0.001), marital satisfaction (P = 0.042), mental health (P = 0.006), and positive psychological well-being (P < 0.001), and alleviating depression (P = 0.015) in CRC couples. For role tendency, the intervention found to be more effective in CRC spousal caregivers' positive psychological well-being compared to the patients (P = 0.037). CONCLUSION: The couple-based dyadic coping intervention is effective in promoting dyadic coping and improving psychological adjustment in CRC couples. More studies were needed to further evaluate the program and its long-term efficacy in the future. In addition, given the positive effects of the intervention, clinical nursing stuffs may consider implementing such intervention in their routine work while caring for CRC couples.

Development of capability lists for neonatal critical care at three levels in China: a modified Delphi study.

BACKGROUND: The standardised management of neonatal critical care centres can help improve health outcomes of vulnerable newborns. Guidance is required to update evidence related to construction and management of neonatal critical care centres in China. OBJECTIVE: To establish expert consensus on the essential capability lists for neonatal critical care at three levels in China. DESIGN AND SETTING: According to China's administrative divisions, the Chinese guidelines stratifies neonatal critical care into three levels: county level (basic and special care), city level (intensive care) and province level (comprehensive care including neonatal surgery and more subspecialty interventions). A modified Delphi study was conducted. A group of 20 neonatologists from the Chinese Association of Neonatologists rated the importance of capability items on a 5-point Likert scale. RESULTS: At county level, the list consisted of 29 items related to basic and special care, and 3 items were unanimously rated very important by all experts: neonatal resuscitation, endotracheal intubation and continuous positive airway pressure ≥72 hours. At city level, group consensus defined 38 items as essential. Besides the essential items of county level, more items for intensive care were included in city level. At province level, 64 items reached consensus, including neonatal surgery and more advanced subspecialty interventions. The Kendall's W values showed good agreement among experts in both rounds, and an increase from round 1 to round 2. CONCLUSIONS: We developed the capability lists for neonatal critical care at three levels in China. Neonatal resuscitation should be provided by all levels. Interventions for preterm newborns are stratified according to gestational age and birth weight. Congenital abnormalities requiring surgical services need to be managed in high-level centres.

The effect of a couple-based posttraumatic growth intervention in supporting couples coping with colorectal cancer: A randomized controlled study.

OBJECTIVES: To promote posttraumatic growth (PTG) in colorectal cancer (CRC) couples, a couple-based PTG intervention was conducted, and the intervention had previously proved be feasible in CRC couples. The current study was conducted to validate the effects of intervention in CRC couples. METHOD: This is a randomized controlled study that included 174 CRC couples. All participants were randomized to either the intervention (usual care plus 5-week PTG intervention, n = 87) or the control group (usual care, n = 87). Data were collected from CRC couple dyads at baseline and immediately post-intervention periods. Primary outcome refers to positive changes, and secondary outcomes include marital satisfaction, quality of life (QOL), and anxiety and depression. Multilevel modeling was applied to analyze the intervention effects. RESULTS: Participants in the program showed increased PTG, marital satisfaction, and QOL both physically and mentally, and decreased levels of anxiety and depression over time. And spousal caregivers showed greater improvement in marital satisfaction and physical QOL compared with patients. In addition, significant intervention effects were shown in the participants' benefit finding, physical health and depressive symptoms. CONCLUSION: The study confirmed the effect of the PTG intervention on CRC couples' benefit finding, physical health and depressive symptoms. However, this study only measured outcome variables at two time-points. Future studies should add follow-up assessments to evaluate long-term effects of the intervention in CRC couples.

Valorization of recycled wastes in pavement preventive maintenance: A review on reclaimed asphalt pavement and recycled waste tire.

Pavement preventive maintenance (PPM) is critical to ensuring traffic efficiency, road user experience, and safety. However, it imposes significant costs in annual road infrastructure budgets because it requires high-quality and natural material resources. This study provides a systematic and comprehensive review on the use of recycled wastes as an alternative for the natural materials used in PPM mixes. Specifically, the use of recycled waste tires (RWT) and reclaimed asphalt pavement (RAP) in chip seals, microsurfacing, slurry seals, and thin asphalt overlays were discussed. The current state-of-practice in terms of material specification and mix design were comprehensively investigated for PPM mixes containing RAP (RAP-PPM) and PPM with RWT (RWT-PPM). Laboratory and field performances of waste-treated PPM mixes were elaborated and compared with conventional PPM treatments to determine the feasibility of the RAP-PPM and RWT-PPM technologies. Furthermore, current research gaps were identified, and prospects for future investigations were discussed. It is envisaged that this study can provide a sufficient theoretical basis for the widespread practical application and beneficial use of this valuable technology, towards promoting sustainability in pavement maintenance practice.

Veno-arterial extracorporeal membrane oxygenation for respiratory and cardiac support in neonates: a single center experience.

Objective: Extracorporeal membrane oxygenation (ECMO) is an advanced life support that has been utilized in the neonate for refractory respiratory and circulatory failure. Striving for the best outcomes and understanding optimal surgical techniques continue to be at the forefront of discussion and research. This study presents a single-center experience of cervically cannulated neonatal patients on V-A ECMO, a description of our cannulation/decannulation techniques and our patient outcomes. Methods: Single center retrospective review of neonates who received neck V-A ECMO support from January 2012 to December 2022. The data and outcomes of the patients were retrospectively analyzed. Results: A total of 78 neonates received V-A ECMO support. There were 66 patients that received ECMO for respiratory support, the other 12 patients that received ECMO for cardiac support. The median duration of ECMO support was 109 (32-293) hours for all patients. During ECMO support, 20 patients died and 5 patients discontinued treatment due to poor outcome or the cost. A total of 53 (68%) patients were successfully weaned from ECMO, but 3 of them died in the subsequent treatment. Overall 50 (64%) patients survived to hospital discharge. In this study, 48 patients were cannulated using the vessel sparing technique, the other 30 patients were cannulated using the ligation technique. We found no significant difference in the rates of normal cranial MRI at discharge between survivors with and without common carotid artery ligation. Conclusion: We achieved satisfactory outcomes of neonatal ECMO in 11-year experience. This study found no significant difference in early neuroimaging between survivors with and without common carotid artery ligation. The long-term neurological function of ECMO survivors warranted further follow-up and study.

Mesenchymal stem cells-based therapies for severe ARDS with ECMO: a review.

Acute respiratory distress syndrome (ARDS) is the primary cause of respiratory failure in critically ill patients. Despite remarkable therapeutic advances in recent years, ARDS remains a life-threatening clinical complication with high morbidity and mortality, especially during the global spread of the coronavirus disease 2019 (COVID-19) pandemic. Previous studies have demonstrated that mesenchymal stem cell (MSC)-based therapy is a potential alternative strategy for the treatment of refractory respiratory diseases including ARDS, while extracorporeal membrane oxygenation (ECMO) as the last resort treatment to sustain life can help improve the survival of ARDS patients. In recent years, several studies have explored the effects of ECMO combined with MSC-based therapies in the treatment of ARDS, and some of them have demonstrated that this combination can provide better therapeutic effects, while others have argued that some critical issues need to be solved before it can be applied to clinical practice. This review presents an overview of the current status, clinical challenges and future prospects of ECMO combined with MSCs in the treatment of ARDS.
