Abstract
INTRODUCTION The second COPD Biennial organized by the COPD working group of the French Society of Respiratory Diseases took place in Paris (Cochin) on 13th December 2023. STATE OF THE ART Major trends in 2023 were discussed; they encompassed concepts, definitions, biologics, care pathways, pulmonary rehabilitation and complex situations entailed by respiratory infections, cardiovascular comorbidities and pulmonary hypertension, and modalities of oxygen therapy and ventilation. PERSPECTIVES The different talks underlined major changes in COPD including the concepts of pre-COPD, etiotypes, health trajectories and new definitions of exacerbation. Recent results in biologics for COPD open the door to new pharmacological options. Assessment of current care pathways in France highlighted some causes for concern. For example, pulmonary rehabilitation is a key but insufficiently practiced element. Respiratory infections require careful assessment and treatments. Diagnosis and treatment of cardiovascular comorbidities and pulmonary hypertension are of paramount importance. As of late, oxygen therapy and ventilation modalities have evolved, and are beginning to afford more personalized options. CONCLUSIONS As regards COPD, a personalized approach is crucial, placing the patient at the center of the care pathway and facilitating coordination between healthcare providers.

Abstract
BACKGROUND The neurotoxic potential of gadolinium (Gd)-based contrast agents (GBCAs) retention in the brains of patients with type 2 diabetes mellitus (T2DM) is unclear. PURPOSE To determine the deposition and clearance of GBCAs in T2DM rats and the mechanism by which Gd enhances nucleotide-binding oligomerization domain-3 (NLRP3) inflammasome activation. STUDY TYPE Cross-sectional, prospective. ANIMAL MODEL 104 T2DM male Wistar rats. FIELD STRENGTH/SEQUENCE 9.4-T, T1-weighted fast spin echo sequence. ASSESSMENT T2DM (male Wistar rats, n = 52) and control group (healthy, male Wistar rats, n = 52) rats received saline, gadodiamide, Gd-diethylenetriaminepentaacetic acid, and gadoterate meglumine for four consecutive days per week for 7 weeks. The distribution and clearance of Gd in the certain brain were assessed by MRI (T1 signal intensity and relaxation rate R1, on the last day of each week), inductively coupled plasma mass-spectroscopy, ultraperformance liquid chromatography mass spectrometry, and transmission electron microscopy. Behavioral tests, histopathological features, and the effects of GBCAs on neuroinflammation were also analyzed. STATISTICAL TESTS One-way analysis of variance, bonferroni method, and unpaired t-test. A P-value <0.05 was considered statistically significant. RESULTS The movement distance and appearance time in the open field test of the T2DM rats in the gadodiamide group were significantly shorter than in the other groups. Furthermore, the expression of NLRP3, Pro-Caspase-1, interleukin-1β (IL-1β), and apoptosis-associated speck-like protein containing a CARD protein in neurons was significantly higher in the gadodiamide group than in the saline group, as shown by Western blot. Gadodiamide also induced differentiation of microglia into M1 type, decreased the neuronal mitochondrial membrane potential, and significantly increased neuronal apoptosis from flow cytometry. DATA CONCLUSION T2DM may affect both the deposition and clearance of GBCAs in the brain. Informed by the T2DM model, gadodiamide could mediate the neuroinflammatory response by NLRP3 inflammasome activation. LEVEL OF EVIDENCE 1 TECHNICAL EFFICACY: Stage 1.

Abstract
PURPOSE/OBJECTIVE(S) Radiation therapy (RT) is generally given in consecutive daily sessions over multiple weeks. This poses challenges for patients who face barriers such as limited access to public or private transportation, limited financial resources, lack of social support, and long distances to healthcare facilities. Delayed or incomplete RT increases risk for worse clinical outcomes. The potential of rideshare service, which uses a private vehicle for hire arranged through a phone-based application or website, to facilitate timely RT is understudied. MATERIALS/METHODS Retrospective data was collected on patients who received RT at a single institution from 2017-2022. Patient demographic and treatment characteristics were compared between those who did and did not utilize free hospital-provided rideshare service. RT completion rates were analyzed for a 1:1 matched non-rideshare cohort using optimal matching with the scaled Euclidean distance metric, to balance age, sex, race, performance status, number of fractions prescribed, Area Deprivation Index (ADI), distance to treatment center, year of diagnosis, treatment site, intent, and modality. ADI is a validated composite measure of community-level socioeconomic deprivation. RESULTS Of 2,906 patients who underwent RT, 58 utilized free hospital-provided rideshare service. Rideshare utilizers had a lower median age (60 vs 66, p = .02), and were more likely to identify as Black or African American (60 vs 22%, p<.0001) compared to non-rideshare utilizers. Rideshare utilizers also had higher ADI scores (median 9 vs 5, p<.0001), indicating higher socioeconomic disadvantage, and travelled shorter distances for treatment (median 5.0 vs 14.7 miles, p<.0001). More rideshare utilizers underwent RT for curative intent (79 vs 50%, p<.0001), concordant with a higher number of fractions prescribed (median 28 vs 5, p<.0001) as well as longer treatment course duration (median 39 vs 13 days, p<.0001). The most common treatment sites were head and neck (31%) and breast / chest wall (22%) for rideshare utilizers, and pelvis (27%) and brain (21%) for non-rideshare utilizers (p<.0001). Volumetric modulated arc therapy followed by 3D conformal were the most common treatment modalities in both groups. The matched cohort analysis revealed that RT completion rates were significantly higher for rideshare vs non-rideshare utilizers at 96 vs 81% (p = .01) overall, and 98 vs 78% (p = .01) for patients undergoing treatment with curative intent. CONCLUSION Even after adjustment for socioeconomic, clinical, and treatment characteristics, utilization of free hospital-provided rideshare service was associated with improved RT completion rates. These findings are notable as the majority of rideshare utilizers come from socioeconomically marginalized communities, and would otherwise be expected to face significant barriers to RT completion.

Abstract
A Gram-stain-negative, rod-shaped, polar flagellated or stalked and non-spore-forming bacterium, designated LB-2T, was isolated from activated sludge. Growth was observed at 20-30 °C (optimum 28 °C), pH 6.0-8.0 (optimum pH 7.0) and salinity of 0-0.5% (w/v; optimum 0.5%). Phylogenetic analysis based on the 16S rRNA gene indicated that strain LB-2T belongs to the genus Sphingomonas and showed the highest sequence similarity (96.7%) and less than 96.7% similarities to other type strains. The genome size of strain LB-2T was 4.10 Mb, with 66.8 mol% G + C content. The average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) values between strains LB-2T and S. canadensis FWC47T were 77.8% and 21%, respectively. The predominant cellular fatty acids were summed feature 8 (C18:1ω7c and/or C18 : 1ω6c) and C16:0. The major polar lipids were aminolipid, glycolipid, sphingoglycolipid, phosphatidylcholine, phosphatidylglycerol, four unidentified lipids, glycophospholipid, phosphatidylethanolamine and diphosphatidylglycerol. The predominant respiratory quinone was Q-10 and the major polyamine was sym-homospermidine. On the basis of phenotypic, genotypic and phylogenetic evidences, strain LB-2T represents a novel species in the genus Sphingomonas, for which the name Sphingomonas caeni sp. nov. is proposed. The type strain is LB-2T (GDMCC 1.3630T = NBRC 115,102T).

Abstract
Quinolinic acid (QA) is an essential nitrogen-containing aromatic heterocyclic compounds in organisms and it also acts as an important intermediate in chemical industry, which has strong neurotoxicity and cytotoxicity. The wide range of sources and applications caused the release and accumulation of QA in the environment which might poses a hazard to ecosystems and human health. However, few research on the degradation of QA by microorganisms and toxicity of QA and its metabolites were reported. Alcaligenes faecalis JQ191 could degrade QA but the genetic foundation of QA degradation has not been studied. In this study, the gene cluster quiA1A2A3A4 was identified from A. faecalis JQ191, which was responsible for the initial catabolism step of QA. The quiA1A2A3A4 gene cluster encodes a novel cytoplasmic four-component hydroxylase QuiA. The 1H nuclear magnetic resonance indicated that QuiA catalyzed QA to 6-hydroxyquinolinic acid (6HQA) and the H218O-labeling analysis confirmed that the hydroxyl group incorporating into 6HQA was derived from water. Toxicity tests showed that the QA could approximately inhibit 20%-80% growth of Chlorella ellipsoidea, and 6HQA could relieve at least 50% QA growth inhibition of Chlorella ellipsoidea, indicating that the 6-hydroxylation of QA by QuiA is a detoxification process. This research provides new insights into the metabolism of QA by microorganism and potential application in the bioremediation of toxic pyridine derivatives-contaminated environments.

Abstract
Abstract
Aim
The incidence of paraoesphageal hiatus hernia (PEH) has changed over the last several years. This study aims to ascertain the difference in the presentation of PEH requiring operative intervention at our unit because of the COVID-19 pandemic
Material & Methods
We conducted a retrospective review of procedures performed by a single surgeon for PEH in a district general hospital. We compared cases from 2016 to March 2020 and during the initial period of the COVID-19 pandemic in 2020.
Results
39 consecutive cases were identified undergoing PEH related procedures. The median age was 66 (IQR 26), with slight female predominance (M:F ratio of 5:6). 28 cases (71.8%) were performed as elective cases.
After the 2020 March lockdown, there were 10 cases of PEH repair performed with 78% performed as emergency procedures, compared to 30 cases in the preceding 5 years and 10% performed as emergency cases. Chi-square test to examine the association between COVID-19 pandemic and emergency procedure, X2(1, N=39)=14.199, p=0.000164.
Pre-COVID19 the types of procedures included 76.7% were fundoplication with suture crural closure, 10% were fundoplication with mesh repair, 3.3% biological mesh repair, 3.3% with suture closure of the crural and 6.7% had suture gastropexy. During the COVID-19 period, 44.4% were gastropexy, 33.3% were gastrostomy tube insertion and 22.2% fundoplication performed.
Conclusion
We have seen significantly more emergency PEH related procedures performed and using a variety of procedures. This leads to the consideration of whether current emergency general surgery training can equip trainees for future independent practice.

Abstract
Abstract
Introduction
Functional tricuspid regurgitation (TR) is a turning point in cardiac diseases. Symptoms typically appear late, and the optimal timing for proposing a valve repair remains a challenge. We sought to analyse the characteristics of right heart remodelling in patients with significant functional TR to identify the parameters that could be used in an easily achievable and fair prognostic model predicting clinical events.
Methods
We designed a prospective observational French multicentre study including 160 patients with significant functional TR (effective regurgitant orifice area >30mm2) and LVEF >40%. Clinical, echocardiographic, and ECG data were collected at baseline, and at the 1- and 2-year follow-up. The primary outcome was all-cause death or hospitalization for heart failure.
Results
At 2 years, 56 patients (35%) achieved the primary outcome. The subset with events showed more advanced right heart remodelling at baseline, but similar TR severity. Right atrial volume index (RAVI) and the TAPSE/sPAP ratio, reflecting right-ventricle-pulmonary artery coupling, were 73 mL/m2 and 0.40 versus 64.7 mL/m2 and 0.50 in the event vs event-free group, respectively (both p<0.05). None among all the clinical and imaging parameters tested had a significant group × time interaction. In multivariable analysis, the model including TAPSE/sPAP ratio >0.4 (OR=0.41, 95%CL 0.2 to 0.82) and RAVI >60 mL/m2 (OR=2.13, 95%CL 0.96 to 4.75) permitted the fairest and most parsimonious prognostic evaluation.
Conclusion
RAVI and TAPSE/sPAP are relevant for predicting the risk for event at 2-year follow-up in patient with an isolated functional TR.

Abstract
The treatment of complex cerebrovascular diseases (CCVDs) at the skull base, such as complex intracranial aneurysms, carotid-cavernous sinus fistulas, and intracranial artery traumatic injuries, is a difficult clinical problem despite advances in endovascular and surgical therapies. Covered stents or stent graft insertion is a new concept for endovascular treatment that focuses on arterial wall defect reconstruction, differing from endovascular lesion embolization or flow diverter therapies. In recent years, covered stents specifically designed for cerebrovascular treatment have been applied in the clinical setting, allowing thousands of patients with CCVDs to undergo intraluminal reconstruction treatment and achieving positive results, even in the era of flow diverters. Since there is no unified reference standard for the application of covered stents for treating CCVDs, it is necessary to further standardize and guide the clinical application of this technique. Thus, we organized authoritative experts in the field of neurointervention in China to write an expert consensus, which aims to summarize the results of covered stent insertion in the treatment of CCVDs and propose suitable standards for its application in the clinical setting. Based on the contents of this consensus, clinicians can use individualized intraluminal reconstruction treatment techniques for patients with CCVDs.

Abstract
Dicamba, an important hormone-type systemic herbicide, is widely used to control more than 200 kinds of broadleaf weeds in agriculture. Due to its broad-spectrum, high efficiency and effectively killing glyphosate-resistant weeds, dicamba is considered as an excellent target herbicide for the engineering of herbicide-resistant crops. In this study, an efficient dicamba-degrading microbial consortium was enriched from soil collected from the outfall of a pesticide factory. The enriched consortium could almost completely degrade 500 mg/L of dicamba within 12 h of incubation. A novel tetrahydrofolate (THF)-dependent dicamba demethylase gene, named dmt06, was cloned from the total DNA of the enriched consortium. Dmt06 shared the highest identity (72.3%) with dicamba demethylase Dmt50 from Rhizorhabdus dicambivorans Ndbn-20. Dmt06 was expressed in Escherichia coli BL21 and purified to homogeneity using Co2+-charged nitrilotriacetic acid affinity chromatography. The purified Dmt06 catalyzed the transfer of methyl from dicamba to THF, generating the herbicidally inactive metabolite 3,6-dichlorosalicylate (3,6-DCSA) and 5-methyl-THF. The optimum pH and temperature for Dmt06 were detected to be 7.4 and 35°C, respectively. Under the optimal condition, the specific activity of Dmt06 reached 165 nmol/min/mg toward dicamba, which was much higher than that of Dmt and Dmt50. In conclusion, this study cloned a novel gene, dmt06, encoding an efficient THF-dependent dicamba demethylase, which was a good candidate for dicamba-resistant transgenic engineering.

Abstract
BackgroundCommon approaches to valuing health technologies often fail to capture outcomes that matter to patients and families. The treatment goals of people living with rheumatoid arthritis (RA) include common trial endpoints but also include other facets of disease impact. Identifying a feasible and rigorous approach to inclusion of the patient perspective is needed as trialists increasingly seek to incorporate patient-important outcomes in trial design and as varied patient-centered value assessment frameworks emerge. No standard approach is available to systemically identify and quantify patient-important outcomes, nor to include those outcomes in deliberative decision-making. We developed the Patient-Engaged Healthcare Valuation strategy, using principles of goal attainment scaling to frame survey-based goal collection directly from adults.ObjectivesTo develop and test a goal-based method for collecting RA patient input for use in clinical trials and value assessment and evaluating the feasibility of this approach in people with RA.MethodsPatient goals and domains were identified from (1) a literature review (2010-2020) of patient outcomes, goals, and preferences in RA, and (2) discussions with patients and clinicians during two meetings with a steering committee (SC) consisting of clinicians, outcomes researchers, patients/advocates, and health economists. These goals informed the development of a draft survey. Adults with RA were recruited from online patient networks to rate goal importance and suggest additional goals. SC members reviewed the survey findings and assessed feasibility of scaling up goal collection for HTA.ResultsOf 135 articles identified, 17 were retained. An inductive and iterative approach was used to identify and thematically group the final set of 36 goals into 4 domains. The draft survey was cognitively debriefed with 4 adults with RA. The first survey was administered to 20 participants; results informed item revisions and additions for the second round of data collection (n=27).The 47 respondents were mostly White (87%), college-educated (72%) women (93%) living with RA for an average of 15 years; 75% rated their RA as moderate to severe. Free-text goals added in round 1 include: 1) finding specialists who listen to patient input on symptoms; 2) addressing loneliness or isolation; and 3) finding support from or helping others with RA. All Symptom and Life Impact goals were rated as Important or Very Important by ≥85% of participants; endorsement for Management and Treatment goals was somewhat more variable, with ≥85% endorsing these as Somewhat to Very Important. Results suggested that domains match key goals. Steering committee ratings supported the feasibility of this method.ConclusionGoals relevant for RA treatment evaluation can be efficiently identified and rated for importance by patients. Patient-important goals can be incorporated into deliberative healthcare valuation using this method to permit “crowd-sourced” input from people living with RA and to capture heterogeneous patient perspectives in healthcare valuation.Table 1.Top Goals based on rating as “Very Important” by >70% of subjects, from set of 36. “My goals for living with RA are to…”GoalsNot ImportantSomewhat ImportantImportantVery ImportantSymptom Managementimprove the quality of my life with RA0% (0)0% (0)23% (11)77% (36)manage my RA pain0% (0)2% (1)11% (5)87% (41)reduce how my RA pain interferes with my life0% (0)9% (4)17% (8)74% (35)Life Impactreduce the ways in which RA interferes with my life0% (0)2% (1)21% (10)77% (36)be independent in my daily functioning0% (0)4% (1)15% (4)81% (22)Managing my RAfeel like I can manage my RA0% (0)2% (1)26% (12)72% (34)Treatment Featuresunderstand my RA treatment options0% (0)4% (2)21% (10)74% (35)have the information I need to make treatment decisions0% (0)0% (0)19% (9)81% (38)know what to expect with my RA treatment0% (0)2% (1)23% (11)74% (35)find treatments that are effective0% (0)0% (0)6% (3)94% (44)AcknowledgementsI have no acknowledgements to declare.Disclosure of InterestsNone declared

Abstract
Alzheimer's disease (AD) is a progressive and irreversible neurodegenerative disease. To distinguish the stage of the disease, AD classification technology challenge has been proposed in Pattern Recognition and Computer Vision 2021 (PRCV 2021) which provides the gray volume and average cortical thickness data extracted in multiple atlases from magnetic resonance imaging (MRI). Traditional methods either train with convolutional neural network (CNN) by MRI data to adapt the spatial features of images or train with recurrent neural network (RNN) by temporal features to predict the next stage. However, the morphological features from the challenge have been extracted into discrete values. We present a multi-atlases multi-layer perceptron (MAMLP) approach to deal with the relationship between morphological features and the stage of the disease. The model consists of multiple multi-layer perceptron (MLP) modules, and morphological features extracted from different atlases will be classified by different MLP modules. The final vote of all classification results obtains the predicted disease stage. Firstly, to preserve the diversity of brain features, the most representative atlases are chosen from groups of similar atlases, and one atlas is selected in each group. Secondly, each atlas is fed into one MLP to fetch the score of the classification. Thirdly, to obtain more stable results, scores from different atlases are combined to vote the result of the classification. Based on this approach, we rank 10th among 373 teams in the challenge. The results of the experiment indicate as follows: (1) Group selection of atlas reduces the number of features required without reducing the accuracy of the model; (2) The MLP architecture achieves better performance than CNN and RNN networks in morphological features; and (3) Compared with other networks, the combination of multiple MLP networks has faster convergence of about 40% and makes the classification more stable.

Abstract
Computer-aided diagnosis (CAD) has undergone rapid development with the advent of advanced neuroimaging and machine learning methods. Nevertheless, how to extract discriminative features from the limited and high-dimensional data is not ideal, especially for amnesic mild cognitive impairment (aMCI) data based on resting-state functional magnetic resonance imaging (rs-fMRI). Furthermore, a robust and reliable system for aMCI detection is conducive to timely detecting and screening subjects at a high risk of Alzheimer's disease (AD). In this scenario, we first develop the mask generation strategy based on within-class and between-class criterion (MGS-WBC), which primarily aims at reducing data redundancy and excavating multiscale features of the brain. Concurrently, vector generation for brain networks based on Laplacian matrix (VGBN-LM) is presented to obtain the global features of the functional network. Finally, all multiscale features are fused to further improve the diagnostic performance of aMCI. Typical classifiers for small data learning, such as naive Bayesian (NB), linear discriminant analysis (LDA), logistic regression (LR), and support vector machines (SVMs), are adopted to evaluate the diagnostic performance of aMCI. This study helps to reveal discriminative neuroimaging features, and outperforms the state-of-the-art methods, providing new insights for the intelligent construction of CAD system of aMCI.

Abstract
BACKGROUND AND PURPOSE Pediatric supratentorial tumors such as embryonal tumors, high-grade gliomas, and ependymomas are difficult to distinguish by histopathology and imaging because of overlapping features. We applied machine learning to uncover MR imaging-based radiomics phenotypes that can differentiate these tumor types. MATERIALS AND METHODS Our retrospective cohort of 231 patients from 7 participating institutions had 50 embryonal tumors, 127 high-grade gliomas, and 54 ependymomas. For each tumor volume, we extracted 900 Image Biomarker Standardization Initiative-based PyRadiomics features from T2-weighted and gadolinium-enhanced T1-weighted images. A reduced feature set was obtained by sparse regression analysis and was used as input for 6 candidate classifier models. Training and test sets were randomly allocated from the total cohort in a 75:25 ratio. RESULTS The final classifier model for embryonal tumor-versus-high-grade gliomas identified 23 features with an area under the curve of 0.98; the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 0.85, 0.91, 0.79, 0.94, and 0.89, respectively. The classifier for embryonal tumor-versus-ependymomas identified 4 features with an area under the curve of 0.82; the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 0.93, 0.69, 0.76, 0.90, and 0.81, respectively. The classifier for high-grade gliomas-versus-ependymomas identified 35 features with an area under the curve of 0.96; the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 0.82, 0.94, 0.82, 0.94, and 0.91, respectively. CONCLUSIONS In this multi-institutional study, we identified distinct radiomic phenotypes that distinguish pediatric supratentorial tumors, high-grade gliomas, and ependymomas with high accuracy. Incorporation of this technique in diagnostic algorithms can improve diagnosis, risk stratification, and treatment planning.

Introduction. Secondary Tricuspid Regurgitation (TR) is a turning point in cardiac diseases. Symptoms occurred too late according to the right heart reverse remodelling capabilities. The ideal timing for proposing a valve repair remains a challenge. We sought to analyse characteristics of patients with significant secondary TR, seeking for changes in parameters over time that could be related to the risk of clinical event.
Material and method. We designed a prospective observational French multicentre study of 160 patients with significant secondary TR (effective regurgitant orifice area > 30 mm²) and LVEF > 40%; we collected clinical, echocardiographic, and EKG data at baseline, 1- and 2-year follow-up. All echocardiographies were centrally analyzed. The primary outcome was death or hospitalization for heart failure
Results. At 2-year 95 patients (59.3%) presented the primary outcome. They had significant morphological and functional alteration of the right heart parameters. Right Atrial Volume Index (RAVI) and right ventricular free wall Strain were respectively 73mL/m² and -19.8% versus 64.7mL/m² and 22.3% in the event-free group. None of them had significant group*time interaction. In the multivariable analysis, TAPSE/sPAP ratio > 0.4 (OR = 0.41 95%CL 0.2 to 0.82) associated to RAVI > 60mL/m² (OR = 2.13 95%CL 0.96 to 4.75) were the two independent parameters that enable the fairest and parsimonious evaluation.
Conclusion. We demonstrated that short analysis using RAVI and TAPSE/sPAP almost reached us to an easier patient assessment by limiting the number of involved parameters. These parameters are now to be for defining the best timing and response to interventions. Abstract Figure. LAVI and TAPSE/sPAP according to events

Abstract
Background: Donor-derived cell-free DNA (ddcfDNA) has been suggested as an indicator of allograft injury in adult and pediatric kidney transplantation (KTx). However, the dynamics of ddcfDNA in pediatric KTx have not been investigated. In addition, it has not been demonstrated whether donor-recipient (D/R) size mismatch affect ddcfDNA level. Methods: Pediatric KTx recipients with a single donor kidney were enrolled and followed up for 1 year. ddcfDNA, calculated as a fraction (%) in the recipient plasma, was examined longitudinally within 3 months post-transplant. D/R size mismatch degree was described as D/R height ratio. The 33rd percentile of D/R height ratio (0.70) was used as the cut-off to divide the patients into low donor-recipient height ratio group (<0.70) and high donor-recipient height ratio group (≥0.70). The dynamics of ddcfDNA were analyzed and the impact factors were explored. Stable ddcfDNA was defined as the first lowest ddcfDNA. ddcfDNA flare-up was defined as a remarkable elevation by a proportion of >30% from stable value with a peak value >1% during elevation. Results: Twenty-one clinically stable recipients were enrolled. The median D/R height ratio was 0.83 (0.62–0.88). It took a median of 8 days for ddcfDNA to drop from day 1 and reach a stable value of 0.67% (0.46–0.73%). Nevertheless, 61.5% patients presented ddcfDNA>1% at day 30. Besides, 81.0% (17/21) of patients experienced elevated ddcfDNA and 47.6% (10/21) met the standard of ddcfDNA flare-up. Donor-recipient height ratio was an independent risk factor for ddcfDNA flare-up (odds ratio = 0.469 per 0.1, 95% CI 0.237–0.925, p = 0.029) and low donor-recipient height ratio (<0.70) was found to increase the risk of flare-up occurrence (odds ratio = 15.00, 95% CI 1.342–167.638, p = 0.028). Conclusions: ddcfDNA rebounds in many stable pediatric KTx recipients without rejection. This may be induced by significant D/R size mismatch and may affect its diagnostic performance at the early phase after pediatric KTx in children.

Abstract
Increased expression of histone deacetylases (HDACs) affiliated to the epigenetic regulation is common aberration in prostate cancer (PCa). We have confirmed that hepatocyte cell adhesion molecule (hepaCAM), acting as a tumor suppressor gene, is rarely expressed in PCa previously, However, the mechanisms of which is still unknown. The level of histone acetylation reportedly may involve anti-oncogene transcription and expression. In this study, we investigated the effect of panobinostat, the broad-spectrum histone deacetylases inhibitor, on PCa LNCaP and DU145 cell growth, and observed re-expression of hepaCAM when treated with panobinostat. We demonstrated that intranuclear acetylation of lys9 of histone H3 (Ac-H3K9) were increased, while that of both mRNA and protein of HDAC1, HDAC3, and HDAC4 were decreased when the treating concentration of panobinostat increased. We confirmed the relationship between histone acetylation and the expression of hepaCAM and AR in prostate cancer tissues. We also confirmed that panobinostat could overcome the resistance for androgen deprivation therapy (ADT). Further, we combined panobinostat with Ad-hepaCAM, which resulted in significantly increased antitumor activity and significant attenuation of the proliferation-associated genes CCND1 and PCNA compared to each single treatment. In conclusion, panobinostat may enhance the acetylation of lys9 of histone 3 and reverse the hepaCAM expression through its inhibitory effect on HDACs activity in PCa LNCaP and DU145 cells; Ad-hepaCAM combined with panobinostat may synergistically inhibit the growth of LNCaP and DU145 cells, via a potential mechanism associated with the down-regulation of the expression of CCND1 and PCNA. These findings suggest that this therapeutic strategy should be further developed in clinical trials.

Abstract
Laryngeal cancer is a common type of head and neck malignancy. microRNA is implicated in the development and progression of various tumours. The present study aimed to explore the potential roles and mechanisms of miR-646 in laryngeal carcinoma cells. We detected the expression of miR-646 and observed that miR-646 was reduced in laryngeal cell lines. Subsequently, the proliferation, migration and invasion of TU212 and TU686 cells were evaluated using CCK-8 assays, cell proliferation ELISA BrdU and transwell assays after transfection with miR-646 mimic. Overexpression of miR-646 attenuated the proliferative and invasive abilities of TU212 and TU686 cells. Dual luciferase reporter assay confirmed that glutathione peroxidase 1 (GPX1) is a direct target of miR-646. Interestingly, restoration of GPX1 promoted cell proliferation and migration, and reversed the biological activities of miR-646 in cell proliferation and migration. It is worth noting that miR-646 overexpression blocked the activation of PI3K/AKT pathway, and this was partly abrogated by GPX1. 740Y-P, a PI3K agonist abolished the effects of miR-646 on cell proliferation and invasion. Taken together, miR-646 prohibited the proliferation and invasion of laryngeal carcinoma cells through the PI3K/AKT pathway via targeting GPX1.

Abstract
Complexly contaminated river sediment caused by reducible and oxidizable organic pollutants is a growing global concern due to the adverse influence on ecosystem safety and planetary health. How to strengthen indigenous microbial metabolic activity to enhance biodegradation and mineralization efficiency of refractory composite pollutants is critical but poorly understood in environmental biotechnology. Here, a synergetic biostimulation coupling electrode with zero-valent iron (ZVI) was investigated for the bioremediation of river sediments contaminated by 2,4,6-tribromophenol (TBP, reducible pollutant) and hydrocarbons (oxidizable pollutants). The bioremediation efficiency of ZVI based biostimulation coupling electrode against TBP debromination and hydrocarbons degradation were 1.1-3 times higher than the electrode used solely, which was attributed to the shape of distinctive microbial communities and the enrichment of potential dehalogenators (like Desulfovibrio, Desulfomicrobium etc.). The sediment microbial communities were significantly positively correlated with the enhanced degradation efficiencies of TBP and hydrocarbons (P < 0.05). Moreover, the coupled system predominately increased positive microbial interactions in the ecological networks. The possible mutual relationship between microbes i.e., Thiobacillus (iron-oxidizing bacteria) and Desulfovibrio (dehalogenator) as well as Pseudomonas (electroactive bacteria) and Clostridium (hydrocarbons degraders) were revealed. This study proposed a promising approach for efficient bioremediation of complexly contaminated river sediments.

Abstract
Sensing and imaging pH inside living cells are of paramount importance for better penetrating cellular functions and disease diagnostics. Herein, we engineered an original pH sensor by a simple one-step self-assembly of poly(ethylene glycol) (PEG)ylated phospholipid (DSPE-PEG) and a phenol red small molecule on the surface of upconversion nanoparticles (UCNPs) to form a phospholipid monolayer for sensing and imaging the change of intracellular pH. The sensor showed excellent reversibility and rapid response to the pH variations. Furthermore, this pH sensing system could measure spatial and temporal pH changes during endocytosis and interrogate the pH fluctuations inside cells under external stimuli. Our experimental results revealed that the pH sensor was able to map spatial and temporal pH fluctuations inside living cells, showing its potential application in diagnostics and pH-related study of cell biology.

Abstract
Brain metastases (BMs) are the most common intracranial malignancy with poor prognosis. Patients with intracranial tumors are at greater risk for thrombotic complications and intracranial hemorrhage. Rivaroxaban is a potent oral anticoagulant with the high selectivity of direct factor Xa inhibition. The incidence and severity of rivaroxaban-triggered intratumoral hemorrhage (ITH) in patients with BMs remain unknown. A 57-year-old woman was diagnosed with multiple lung, bone, and BMs from unknown primary cancer origin, and refused any invasive procedures to confirm tumor pathology. However, this patient had a relatively favorable outcome after treating with cabozantinib, an inhibitor of multiple tyrosine kinases. The patient survived over 2 years and developed deep vein thrombosis of right lower limb. Oral rivaroxaban was prescribed, and the multifocal catastrophic ITH was encountered after 1 week. The last head computed tomography imaging revealed a rare but typical image of diffuse hemorrhagic metastases. Hemorrhagic-prone BMs, therapeutic rivaroxaban, and cabozantinib treatment increase risks to develop ITH. In this case rivaroxaban was the trigger to this terminal event. This case is a miserable lesson and keeps reminding us to stay vigilant in clinical practice even when there is a potential benefit for anticoagulation in such population.

Abstract
Objective: Our group aimed to investigate the expression pattern of miRNA-873-5p in cervical cancer (CC) patients and its association with CC progression. Methods: Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) was applied for the examination of the expressions of miRNA-873-5p in both CC specimens and cell lines. The clinical significance of miRNA-873-5p was statistically analyzed. MTT, colony formation, Transwell and flow cytometry assays were used to detect cell proliferation, metastasis, and apoptosis changes of Hela and Siha cell line. Luciferase reporter assays and Western blots were utilized to identify the target genes of miRNA-873-5p. Western blot and RT-PCR were used to judge the dysregulation of Notch signaling. Results: Our results indicated that miRNA-873-5p expression was distinctly reduced in CC patients. Low miRNA-873-5p expressions were distinctly correlated with positively distant metastasis, The International Federation of Gynecology and Obstetrics (FIGO) stage and poor prognosis of CC patients. A functional assay using miRNA-873-5p mimics indicated that overexpression of miRNA-873-5p distinctly suppressed CC cells proliferation and metastasis, and promoted apoptosis. Bioinformatic assays revealed that miRNA-873-5p may target the 3’-UTR of ZEB1 and lead to the suppression of its translation, which was verified by the use of luciferase assays. Finally, overexpression of miRNA-873-5p suppressed the expressions of Jag1, Maml2 and Hey1. Conclusion: Taken together, we firstly provided evidence that miRNA-873-5p expression was a poor favorable factor for CC patients, and the use of miRNA-873-5p may represent a and potential biomarker and promising therapeutic approach for CC.

Abstract
Objectives The objective of this study was to evaluate whether the non-pharmaceutical interventions (NPIs) introduced to curb the spread of coronavirus disease 2019 (COVID-19) also interrupted the transmission of influenza. Study design This is a descriptive epidemiological study. Methods Data on changes in the number of reported influenza cases, number of influenza-like illness (ILI) visits, ILI percentage and influenza virus positivity were compared between the first 18 weeks of 2020 and the same period of 2019. Results The changes in the weekly average number of influenza cases were statistically significant between 2020 and 2019 (−4319 vs −525 per week; P < 0.05). The slopes of regression lines for the number of ILI visits were also statistically significant between 2020 and 2019 (−911 vs −98 per week; P < 0.05). Conclusions This study found that the prevalence of influenza was substantially decreased when NPIs were implemented for the containment of COVID-19. The prevalence of influenza was substantially decreased when non-pharmaceutical interventions were implemented for the containment of coronavirus disease 2019. Changes in the weekly average number of influenza cases were statistically significant between 2020 and 2019 (−4319 vs −525 per week; P < 0.05). Changes in the number of influenza-like illness visits were also statistically significant between 2020 and 2019 (−911 vs −98 per week; P < 0.05).

Abstract
Premature infants or neonates in need of advanced clinical care must be transported to specialized hospitals. Past studies have examined vibrations experienced by patients during transport; however, multiple confounding factors limit the utility of on-road data. Hence, the development of a standardized test environment is warranted. The overall purpose of this project is to characterize vibrations during neonatal patient transport and develop mitigation strategies to reduce exposure. This paper focusses on the development of a laboratory test environment and procedure that enables studying the equipment vibration in a comprehensive and repeatable manner. For the first time, a complete neonatal patient transport system, including a stretcher, has been mounted on an industrial shaker. Results largely validate the system's ability to simulate on-road vibrations with high repeatability.

Abstract
OBJECTIVE To evaluate the safety and efficacy of LVIS stent-assisted coil embolization in the acute phase of ruptured intracranial aneurysms. METHODS The clinical data of 55 patients with ruptured intracranial aneurysm treated with LVIS stent-assisted coil embolization admitted to Zhongshan Hospital of Xiamen University from January 2016 to December 2018 were analyzed retrospectively. The general data, the characteristics of aneurysms and the occurrence of perioperative complications of the patients were collected. The clinical prognosis of the patients at discharge and 6 months of follow-up was recorded. The Glasgow prognosis score (GOS) was graded as good (5), average (3-4), and poor (1-2), and the cerebral angiography results were recorded immediately after embolization and 6-month follow-up. The aneurysm occlusion was assessed by Raymond grade, Raymond I was complete obliteration, II was residual neck and III was residual aneurysm. RESULTS All 55 patients received LVIS stent-assisted coil embolization within 72 hours of ruptured intracranial aneurysms, and all stents were released successfully, including 16 males (29.1%) and 39 females (70.9%). The median age was 53 (24-80) years old. Anterior circulation aneurysms were found in 49 patients (89.1%) and posterior circulation aneurysms in 6 patients (10.9%). According to Hunt-Hess classification, there were 43 patients with grade I-II (78.2%), 7 patients with grade III (12.7%) and 5 patients with grade IV-V (9.1%). The first digital subtraction angiography (DSA) examination of 55 patients after embolization showed that 41 patients had complete obliteration of aneurysms and 14 had residual neck; and the smaller the aneurysm was, the higher the rate of complete obliteration after embolization was. The proportion of small aneurysms (maximum diameter ≤ 7 mm) in the complete obliteration group was significantly higher than that in the neck residual group (100.0% vs. 64.3%, P < 0.01). Among the 55 patients, there was 1 patient suffered from in-stent thrombosis during embolization, 1 patient suffered from distal vascular thrombosis induced by plaque shedding during embolization, 1 patient suffered from vasospasm during embolization, and 1 patient suffered from postoperative distal cerebral hemorrhage after embolization. In 2 dead patients, 1 died of cardiogenic disease and 1 died of respiratory failure caused by severe pneumonia. At discharge, the prognosis was good in 40 patients, average in 10 patients, and poor in 5 patients; and the higher the Hunt-Hess grade at admission, the worse the prognosis. The proportion of patients with Hunt-Hess grade I-II at admission in the good prognosis group was significantly higher than that in the general prognosis group and the poor prognosis group (90.0% vs. 50.0%, 40.0%, P < 0.01). Of the 55 patients, 39 completed clinical prognosis and cerebral angiography 6 months after embolization for follow-up. All patients had GOS no less than 3, including 32 patients with complete obliteration of aneurysm, 4 with residual neck and 3 with residual aneurysm. The smaller the aneurysm, the higher the rate of complete obliteration at 6-month follow-up was. The proportion of small aneurysm in the complete obliteration group was significantly higher than that in the residual neck group and the residual aneurysm group (100.0% vs. 75.0%, 33.3%, P < 0.01). There was no rebleeding or ischemic complication at 6-month follow-up. CONCLUSIONS LVIS stent assisted coil embolization is safe, effective and feasible in the acute stage of ruptured intracranial aneurysms. Standardizing antiplatelet therapy and dense packing of aneurysms during embolization are the key to reduce bleeding and ischemic complications.

Abstract
BACKGROUND Concerns associated with blended enteral feeds include the risk of blocked tubes and microbial contamination, although the available evidence is limited. The present laboratory-based investigation aimed to examine these risks in a blended feed providing a nutritionally adequate intake for a hypothetical patient. METHODS A one-blended feed recipe was made using three different methods (professional, jug and stick blenders) and three storage procedures. Feed samples were syringed via 10-, 12- and 14-French (Fr) enteral feeding tubes and both blockages and the time taken were recorded. Feed samples were diluted, plated on agars, incubated and bacterial colony-forming units (CFU) counted. After storage at -80 °C, identification was undertaken using 16S rRNA polymerase chain reaction sequencing. RESULTS Two blockages occurred during 27 administrations of feed made using a professional blender, although they were resolved with a water flush. No blockages occurred with the 14-Fr tube and administration was quicker with wider tubes (P < 0.00001). There was no significant difference between the total bacterial CFU of feeds prepared using different methods (P = 0.771) or stored differently. The genus of bacteria identified included Enterococcus, Bacillus, lactose-fermenting Enterobacteriaceae, Pseudomonas and Staphylococcus. Pathogens, such as Clostridium spp., Salmonella spp. and Vibrio spp., were not identified by phenotypic tests used. Sequencing identified Escherichia coli, Shigella spp., Streptococcus lutetiensis and Staphylococcus epidermidis. CONCLUSIONS The present study found no risk of tube blockages when one blended feed recipe made using three methods was delivered via a 14-Fr tube. There is concern about bacterial contamination, although this was not influenced by the methods of preparation or storage used in the present study.
