Abstract
Objective: To investigate the clinical manifestations, treatment characteristics and outcomes of myasthenia gravis (MG) dually positive for anti-acetylcholine receptor antibody (AChR-Ab) and anti-muscle-specific tyrosine kinase antibody (MuSK-Ab). Method: MG patients hospitalized in the First Affiliated Hospital of Sun Yat-sen University from August 2017 to November 2020 were retrospectively collected. Thirty-four MuSK-Ab positive MG (MuSK-MG) patients, 11 double-antibodies positive MG (DP-MG) patients, and 80 AChR-Ab positive MG (AChR-MG) patients were included and allocated to three different groups. The clinical data of patients in the three groups were collected, and the differences of demographic characteristics, clinical manifestations and treatment outcomes between DP-MG patients and AChR-MG and MuSK-MG patients were analyzed. Result: The proportion of female and male patients in DP-MG group was 7/11 and 4/11 respectively, and the onset age of DP-MG was (41±27) years.The difference in gender distribution between DP-MG and AChR-MG groups was statistically significant (P<0.05). The proportion of extraocular muscle involvement in the DP-MG and MuSK-MG groups (8/11 and 52.9%) was lower than that in the AChR-MG group (83.8%), and the difference was statistically significant (P<0.05). The incidence of myasthenia crisis in DP-MG and MuSK-MG groups (54.5% and 61.8%) were higher than that in AChR-MG group (20.0%), with astatistically significant difference(P<0.05). The positive rate of neostigmine test in DP-MG and MuSK-MG groups(8/11 and 74.2%) were lower than that of AChR-MG group (96.8%), and the positive rate of low frequency repetitive nerve stimulation (RNS) in DP-MG group (5/10) was lower than that in AChR-MG group (85.1%), with statistically significant differences (all P<0.05). MuSK-Ab titer was positively correlated with the course of disease (r=0.466, P<0.05), and antibody titer decreased after symptom improvement (P<0.05). The response of patients in DP-MG and MuSK-MG groups to cholinesterase inhibitors (2/11 and 9.1%) was worse than that in the AChR-MG group (66.3%), and the incidence of side effects in the two groups (5/11 and 39.4%) was higher than that in the AChR-MG group (15.0%), with statistically significant differences (all P<0.05). There were 4 DP-MG patients underwent thymectomy, and the pathological results detected two cases of thymoma and two cases of thymic hyperplasia. Subsequent follow-up showed that 5 (5/11) DP-MG patients achieved minimal manifestation status or better status. Conclusion: The gender distribution, age of onset, pharmacological characteristics and electrophysiological examination of DP-MG patients were similar to those of MuSK-MG patients, but the severity of DP-MG patients was between that of AChR-MG and MuSK-MG patients.

Abstract
Objective: To explore the different coagulation state in patients with adenomyosis and its clinical significance. Methods: Clinical data of the patients admitted to the First Affiliated Hospital of Nanjing Medical University from January 2017 to December 2021 were retrospectively analyzed. (1) Differential coagulation state between 25 healthy women and 25 patients with adenomyosis were compared during menstrual and non-menstrual periods. (2) The coagulation indexes of 145 patients with adenomyosis (observation group 1) and 129 patients with cervical intraepithelial neoplasia grade Ⅲ (control group 1) who underwent hysterectomy in non-menstrual period were compared. (3) The coagulation indexes of 154 patients with adenomyosis (observation group 2) and 147 women without myometrial lesions (control group 2) who underwent endometrial curettage during uterine bleeding period were compared. (4) Correlations of coagulation index with cancer antigen 125 (CA125), cancer antigen 19-9 (CA19-9) and uterine volume in patients with adenomyosis were analyzed. Results: (1) The coagulation state of each health women during the menstrual and non-menstrual period showed no significant differences (all P>0.05). For the 25 patients with adenomyosis, fibrinogen [FIB; 2.61 g/L(2.50-3.10 g/L)] and D-dimer [0.60 mg/L (0.40-1.00 mg/L)] in the menstrual period were significantly higher than those in the non-menstrual period [2.25 g/L (1.90-2.70 g/L) and 0.27 mg/L (0.20-0.40 mg/L), respectively; both P<0.01], while thrombin time [TT; 16.70 s (16.10-17.40 s)] in the menstrual period was significantly lower than that in the non-menstrual period [17.95 s (17.20-18.40 s); P<0.01]. (2) In the non-bleeding period, D-dimer [0.26 mg/L (0.20-0.40 mg/L)] and platelet count [257.0×109/L (212.0×109/L-308.5×109/L)] of observation group 1 were significantly higher than those of control group 1 (all P<0.01). Besides, FIB (r=0.237, P=0.004) and D-dimer (r=0.373, P<0.001) were positively correlated with CA125, while prothrombin time (PT; r=-0.208, P=0.012) and internationalized normalized ratio of plasma prothrombin time (PT-INR; r=-0.201, P=0.015) were negatively correlated with CA19-9. (3) In the bleeding period, PT [10.70 s (10.10-11.20 s)] and PT-INR [0.93 (0.90-1.00)] of observation group 2 were significantly lower than those of control group 2 (all P<0.01), while D-dimer [0.41 mg/L (0.20-0.80 mg/L)] was significantly higher than that in the control group 2 (P<0.001). Furthermore, FIB (r=0.252, P=0.038) and D-dimer (r=0.321, P=0.008) were positively correlated with uterine volume, while activated partial thromboplastin time (APTT; r=-0.190, P=0.018) and TT (r=-0.304, P=0.012) were negatively correlated with uterine volume. (4) During non-menstrual period and uterine bleeding period, APTT and TT in patients of observation group 1 and 2 combined with anemia were significantly lower than those of non-anemia patients (all P<0.05). Conclusion: Patients with adenomyosis have a tendency to hypercoagulability in both the uterine bleeding and non-bleeding periods, which may be related to enlarged uterine volume, increased serum CA125 and anemia.

Abstract
Nephrotic syndrome is the most common clinical presentation of glomerular disease in elderly patients, and renal biopsy is an important diagnostic resource. The aim of this study was to describe nephrotic syndrome among elderly patients in Brazil, focusing on tubulointerstitial and vascular involvement. This was a retrospective study of patients over 65 years of age with nephrotic syndrome who underwent renal biopsy between January 2012 and December 2019. Of the 123 renal biopsies that occurred during the study period, 44 (35.8%) were performed for the investigation of nephrotic syndrome. Among those 44 cases, the main etiologies were membranous nephropathy in 13 cases (29.5%), amyloidosis in ten (22.7%), non-collapsing focal segmental glomerulosclerosis (FSGS) in four (9.1%), and collapsing FSGS in four (9.1%). Patients with minimal change disease (MCD) had the lowest degree of interstitial fibrosis compared with the other glomerulopathies, and histological signs of acute tubular necrosis (ATN) were less common among those with amyloidosis than among those with membranous nephropathy, FSGS, or MCD (P=0.0077). Of the patients with ATN, the frequency of acute kidney injury (AKI) was highest in those with MCD (P<0.001). All patients had some degree of vascular involvement, regardless of the type of glomerulopathy. In conclusion, the second most common cause of nephrotic syndrome in this population was amyloidosis, and acute interstitial tubule involvement was more marked in MCD. Vascular involvement is something that cannot be dissociated from the age of the patient and is not only due to the underlying glomerulopathy.

Abstract
Emerging evidence suggests that small vessel disease (SVD) is a risk factor for clinical dementia and may contribute to AD neuropathological changes. Watershed brain regions are located at the most distal areas between arterial territories, making them vulnerable to SVD-related changes. We examined the association of pathologic markers of SVD, specifically arteriolosclerosis in watershed brain regions, with AD pathologic changes. Participants (N = 982; mean age-at-death = 90; 69% women) were enrolled as part of one of two cohort studies of aging and dementia. At autopsy, neuropathological evaluation included semi-quantitative grading of arteriolosclerosis pathology from 2 cortical watershed regions: the anterior watershed (AWS) and posterior watershed (PWS), densities for cortical β-amyloid and tau-tangle pathology, and other common age-related pathologies. Linear regression models examined the association of watershed arteriolosclerosis pathology with β-amyloid and tau-tangle burden. In follow-up analyses, available ex-vivo MRI and proteomics data in a subset of decedents were leveraged to examine the association of whole brain measure of WMH, as a presumed MRI marker of SVD, with β-amyloid and tau-tangle burden, as well as to examine the association of watershed arteriolosclerosis with proteomic tau. Watershed arteriolosclerosis was common, with 45% of older persons having moderate-to-severe arteriolosclerosis pathology in the AWS region, and 35% in the PWS. In fully adjusted models that controlled for demographics and common age-related pathologies, an increase in severity of PWS arteriolosclerosis was associated with a higher burden of tau-tangle burden, specifically neocortical tau burden, but not with β-amyloid. AWS arteriolosclerosis was not associated with β-amyloid or tau pathology. Ex-vivo WMH was associated with greater tau-tangle pathology burden but not β-amyloid. Furthermore, PWS arteriolosclerosis was associated with higher abundance of tau phosphopeptides, that promote formation of tau aggregates. These data provide compelling evidence that SVD, specifically posterior watershed arteriolosclerosis pathology, is linked with tau pathological changes in the aging brain.

Abstract
OBJECTIVE To investigate the role of miRNAs in amniotic fluid exosomes in growth and development of fetuses with Down syndrome (DS). METHODS Amniotic fluid were collected from 20 fetuses with DS and 20 normal fetuses (control) to extract amniotic exosome miRNA. MicroRNA sequencing technique was used to identify the differentially expressed miRNAs between the two groups, for which gene ontology (GO) and pathway analysis was performed. Three differentially expressed miRNAs with the strongest correlation with DS phenotype were selected for qPCR verification. Dual luciferase reporter assay was used to verify the activity of let-7d-5p for targeted regulation of BACH1. RESULTS We identified 15 differentially expressed miRNAs in DS as compared with the control group, among which 7 miRNAs were up-regulated and 8 were down-regulated. Target gene prediction results showed that the differentially expressed miRNAs targeted 17 DS-related genes. GO analysis revealed that the main functions of the target genes involved protein binding, protein transport, ATP binding, transferase activity and synapses. Pathway analysis revealed that the functional pathways were closely related with the development of the nervous system. qPCR results showed that the expression levels of miR-140-3p and let-7d-5p were significantly lower in DS group than in the control group (P < 0.05), as was consistent with miRNA sequencing results; the expression level of miR-4512 was significantly higher in DS group than in control group (P < 0.05), which was contrary to miRNA sequencing results. The results of double luciferase reporter gene assay confirmed that let-7d-5p was capable of targeted regulation of BACH1 expression. CONCLUSION Let-7d-5p in amniotic fluid exosomes may promote oxidative stress events in the brain of fetuses with DS by regulating BACH1 expression.

Abstract
Objective: To evaluate the perioperative period and long-term effects of minimally invasive gasless laparoscopic transhiatal esophagectomy (LTE) and minimally invasive combined thoracoscopic and laparoscopic esophagectomy (CTLE) for stageⅠ-Ⅲ cervical esophageal cancer. Methods: The clinical data of 158 consecutive patients with cervical esophageal cancer stageⅠto Ⅲ who underwent minimally invasive CTLE or LTE esophagectomy in the Department of Thoracic Surgery, Beijing Tongren Hospital from January 2008 to December 2019 were retrospectively analyzed. A total of 40 pairs of cases were matched (40 cases of CTLE and 40 cases of LTE surgery) after using the propensity score matching analysis which aimed to balance the influence of confounding factors between groups, including 43 males and 37 females, aged 51 to 81 (62.5±7.0) years old. The perioperative variables and long-term outcomes of the two groups were compared. Results: The operation time ((148.0±31.3) min vs (201.3±48.3) min), intraoperative blood loss ((192.6±77.9) ml vs (387.8±112.4) ml), ICU monitoring time (0 day vs 1 day), and the complication rates of postoperative pneumonia (0 vs 15%) and arrhythmia (2.5% vs 20%) were lower in the LTE group than that of in the CTLE group(all P<0.05). The number of lymph node dissections in the CTLE group was higher than that of in the LTE group (21.2±6.1 vs 12.9±4.3, P<0.001). The 3-and 5-year overall survival (OS) rate and disease-free survival (DFS) rate in the LTE group (OS: 53.53% and 34.27%, DFS: 43.62% and 24.89%, respectively) and the CTLE group (OS: 59.48% and 37.29%, DFS: 49.12% and 28.82%, respectively) had no statistical differences (all P>0.05). Conclusion: The LTE group has advantages in reducing operation time, intraoperative bleeding, ICU monitoring time, postoperative incidence of pneumonia and arrhythmia, and its long-term prognosis is comparable to that of the CTLE group.

Abstract
Objective: To compare the differences of water barrier function between keloids and its surrounding normal skin in patients with keloids, and to explore the primary mechanism. Methods: A cross-sectional observational study was conducted. From October 2020 to March 2021, 30 patients with keloids who met the inclusion criteria visited Shanghai Ninth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine, including 18 females and 12 males, aged 20-48 years. The transepidermal water loss (TEWL) of their keloids and the surrounding normal skin of the 30 patients were measured by multi probe adapter on the reception day. The keloid tissues and normal skin of 5 patients after keloid repair surgery were processed for hematoxylin-eosin staining to measure the thickness of epidermis. Immunohistochemistry was performed on samples from 3 of those 5 patients to detect the expressions of cytokeratin-10, involucrin, and filaggrin in keloids and normal skin. Data were statistically analyzed with paired sample t test and independent sample t test. Results: On the reception day, the TEWL of keloids of 30 patients was 9.0 (6.9, 13.4) g·m-2·h-1 and the TEWL of the normal skin was 8.1 (6.4, 18.1) g·m-2·h-1, between which the difference was not statistically significant (t=0.44, P>0.05). After keloid repair surgery, the thickness of epidermis in the keloids of 5 patients was (194±44) μm, which was significantly thicker than that of the normal skin (44±11) μm, (t=6.88, P<0.01). Furthermore, increased keratinocytes, lack of normal epidermal ridge structures, and thickened stratum corneum were observed in the keloid area. After keloid repair surgery, the expression level of cytokeratin-10 in keloids was significantly lower than that in normal skin of 3 patients (t=8.50, P<0.01), but there were no statistically significant differences in the expression levels of involucrin or filaggrin between keloids and normal skin (with t values of 0.07 and 0.96, respectively, P>0.05). Conclusions: Keloid tissue from patients with keloids displays increased number of keratinocytes and thickened epidermis. But the water barrier function in keloid area is similar to the surrounding normal skin, suggesting that TEWL may not be the main mechanism lead to the persistent development of keloids.

Abstract
Cold atmospheric plasma (CAP) is selective against many cancers with little side effect, yet its molecular mechanism remains unclear. Through whole transcriptome sequencing followed by assays in vitro, in vivo and using clinical samples, we propose CAP as a promising onco-therapy targeting cancer stemness via the AQP3/FOXO1 axis. CAP-generated reactive species penetrated cells via AQP3 and suppressed RPS6KA3, a shared kinase of AQP3 and FOXO1. Reduced AQP3-19Y phosphorylation suppressed SCAF11-mediated AQP3-5K K48-ubiquitination that led to sabotaged FOXO1 stability. Inhibited FOXO1 phosphorylation retarded its regulatory activities in maintaining cancer stemness including ALDH1 and IL6. Enhanced anti-cancer efficacy was observed through combining CAP with Atorvastatin in vitro and in vivo. We propose CAP as a 'selective' onco-therapeutic against cancer stemness, with the AQP3/FOXO1 axis being one molecular mechanism. We report SCAF11 as an E3 ubiquitin ligase of both AQP3 and FOXO1, identify AQP3-5K as an AQP3 K48-ubiquitination site, and emphasize the essential role of AQP3-19Y in this process. We reposition Atorvastatin into the onco-therapeutic portfolio by synergizing it with CAP towards enhanced efficacy. We anticipate the efficacy of CAP in targeting malignancies of high stemness alone or as an adjuvant therapy towards the hope of ultimate cancer cure.

Abstract
Mitochondrial DNA copy number (mtDNA-CN) measured from blood specimens is a minimally invasive marker of mitochondrial function that exhibits both inter-individual and intercellular variation. To identify genes involved in regulating mitochondrial function, we performed a genome-wide association study (GWAS) in 465,809 White individuals from the Cohorts for Heart and Aging Research in Genomic Epidemiology (CHARGE) consortium and the UK Biobank (UKB). We identified 133 SNPs with statistically significant, independent effects associated with mtDNA-CN across 100 loci. A combination of fine-mapping, variant annotation, and co-localization analyses was used to prioritize genes within each of the 133 independent sites. Putative causal genes were enriched for known mitochondrial DNA depletion syndromes (p = 3.09 × 10-15) and the gene ontology (GO) terms for mtDNA metabolism (p = 1.43 × 10-8) and mtDNA replication (p = 1.2 × 10-7). A clustering approach leveraged pleiotropy between mtDNA-CN associated SNPs and 41 mtDNA-CN associated phenotypes to identify functional domains, revealing three distinct groups, including platelet activation, megakaryocyte proliferation, and mtDNA metabolism. Finally, using mitochondrial SNPs, we establish causal relationships between mitochondrial function and a variety of blood cell-related traits, kidney function, liver function and overall (p = 0.044) and non-cancer mortality (p = 6.56 × 10-4).

Abstract
BACKGROUND Osteosarcoma is the most frequent malignant bone malignancy and the current treatments are ineffective. Ivermectin, an anti-protozoal drug, has been shown to have anti-cancer activity. This work investigated the potential of repurposing ivermectin to augment chemotherapy's efficacy in osteosarcoma. METHODS Proliferation, migration and apoptosis assays were performed in ivermectin-treated osteosarcoma cells. Combination studies were performed. Osteosarcoma xenograft mouse model was established to investigate the in vivo efficacy of ivermectin. Intracellular reactive oxygen species (ROS) and mitochondrial superoxide, membrane potential, ATP, 8-OHdG level, protein carbonylation and lipid peroxidation were determined after ivermectin treatment. RESULTS Ivermectin was effective and acted synergistically with doxorubicin in osteosarcoma cells regardless of cellular origin and genetic profiling. This was achieved through suppressing inhibiting growth and migration, and inducing caspase-dependent apoptosis. Ivermectin also significantly inhibited osteosarcoma growth in vivo and its combination with doxorubicin resulted in much greater efficacy than doxorubicin alone. Importantly, the effective dose of ivermectin was clinically feasible and did not cause significant toxicity in mice. Mechanistical analysis showed that ivermectin induced oxidative stress and damage, and mitochondrial dysfunction. CONCLUSIONS Our findings indicate that ivermectin has utility in treating patients with osteosarcoma, especially those resistant to chemotherapy.

Abstract
OBJECTIVE To screen compounds that can selectively inhibit uveal melanoma cells with splicing factor 3B subunit 1 (SF3B1) mutations in comparison with isogenic SF3B1 wild-type counterparts in a cell model of SF3B1 mutant allele knockout. METHODS Principal component analysis was used to analyze transcriptome alternative splicing in TCGA cohorts of uveal melanoma with wild-type SF3B1 and SF3B1 mutations, and abnormal alternative splicing events derived from SF3B1 mutations were identified. The SF3B1 mutant allele in Mel202 cells was knocked out using CRISPR-Cas9 technology, and Sanger sequencing was used to verify the edited sequence. MTT and colony formation assays were used to assess the proliferation of Mel202 and Mut-KO cells. RT-PCR agarose electrophoresis combined with Sanger sequencing was used to determine alternative splicing events in Mel202 and Mut-KO cells. MTT assay was performed to screen the compounds that showed selective inhibitory effect against Mel202 cells with SF3B1 mutation. RESULTS Specific knockout of SF3B1 mutant allele in Mel202 cells obviously promoted the cell proliferation and caused changes in alternative splicing of ZDHHC16 and DYNLL1 transcripts. The screening data showed that 13 compounds had selective inhibitory activity against Mel202 cells with SF3B1 mutation (Fold change≥2), and among them, tetrandrine and lapatinib showed good dose-effect curves. CONCLUSION This study provides a cell screening model for identification of potential individualized treatment drugs for patients with uveal melanoma with SF3B1 mutation.

Abstract
TatD DNases are conserved proteins in a variety of organisms and are considered potential virulence factors in Plasmodium falciparum and Streptococcus pneumoniae. However, the function of TatD DNases has not yet been determined in Trueperella pyogenes, which causes various infections in animals and leads to economic losses. In this study, we describe the roles of TatD DNases in T. pyogenes (TpTatDs). A bioinformatics analysis was performed to investigate the sequence characteristics of TpTatDs, and then the ability of recombinant TatD proteins to hydrolyze DNA was determined in the presence of divalent cations. Moreover, we constructed tatD-deficient mutants. The biofilms formed by the wild-type and mutant strains were observed under a microscope. The mortality and bacterial load in the spleen of mice infected with the wild-type strain and tatD-deficient mutants were determined to obtain insights into the role of TatDs in the virulence of T. pyogenes. Two TatD DNases were identified in T. pyogenes. They were Mg2+-dependent DNases and exhibited DNA endonuclease activity. Compared with those formed by the parental strain, biofilms formed by mutants showed a significantly reduced thickness and biomass. Moreover, mutants produced a lower bacterial load in the spleen of mice and compromised virulence. Our data indicated that TatD DNases in T. pyogenes are involved in biofilm formation and required for virulence during infections.

Abstract
This study was a prospective single arm trial conducted in Zhejiang Jinhua Guangfu hospital from February 2018 to June 2020. A total of 39 patients (32 males and 7 females) with esophageal cancer, aged from 44 to 82 (69±9) years were enrolled. Diffusion weighted magnetic resonance imaging(MR-DWI) was implemented to evaluate the changes of apparent diffusion coefficient(ADC) value before and after chemoradiotherapy. The results showed that the ADC value after chemoradiotherapy was higher than that before treatment[(2.03±0.42)×10⁻³ mm 2/s vs (1.60±0.28)×10⁻³ mm2/s], and there was a positive correlation between the increase of ADC value and the prognosis of patients.

Abstract
Abstract
Purpose
Atrial fibrillation (AF) and heart failure (HF) often coexist. The impact of rate-control regimens in AF and HF patients has not been well understood.
Methods
In this multicenter, prospective registry with one-year follow-up, 1359 persistent or permanent AF patients got enrolled. A 1:1 HF to non-HF propensity score matching was applied to adjust for confounding variables. The primary endpoint was all-cause mortality while the secondary endpoint was defined as cardiovascular death and stroke. Multivariate Cox analysis was performed to evaluate the association between different rate-control treatment and incidence of adverse events.
Results
Before matching, HF patients were much younger and more likely to be female. They had a much higher prevalence of previous myocardial infarction, chronic obstructive pulmonary disease and valvular heart disease. Among 1359 participants, we identified 1016 matched patients. The number of drugs did not affect the risk of all-cause mortality in both cohorts. For non-HF patients, using calcium channel blockers (CCBs) plus digoxin had a significant higher risk of all-cause death (HR=5.703, 95% CI 1.334–24.604, p=0.019) and cardiovascular death (HR=9.558, 95% CI 2.127–42.935, p=0.003) compared with patients not receiving rate-control treatment. The use of beta-blockers, CCBs, digoxin alone, other dual or triple combinations was not related to risk of adverse events in both groups.
Conclusions
The combined use of CCBs and digoxin was related to increase all-cause and cardiovascular mortality in AF patients without HF but not for those with HF. However, the ideal rate-control regimen for AF and HF patients has not been established and well-designed clinical trials are needed.

Abstract
Abstract
Background
Standard scoring system for bleeding risk assessment has not been developed in patients with atrial fibrillation (AF) and acute coronary syndrome (ACS) or undergoing percutaneous coronary intervention (PCI). The study aims to evaluate the predictive value of the HAS-BLED, ORBIT, ARTIA, PARIS, and PRECISE-DEAPT score in patients with AF and ACS/PCI who received both anticoagulant and antiplatelet therapy.
Methods
A total of 930 patients with AF and ACS/PCI receiving both anticoagulant and antiplatelet therapy were consecutively recruited and followed up for 1 year. The primary endpoint was defined according to the bleeding academic research consortium (BARC) criteria as major (BARC 3a, 3b, 3c, and 5) and any bleeding (BARC 2, 3a, 3b, 3c, and 5). The secondary endpoints included major or minor bleeding according to TIMI criteria. Univariate and multivariate logistic regression were performed to evaluate the association between bleeding risk scores and outcomes. Receiver operating characteristic (ROC) curves were constructed and c-statistics were calculated to evaluate the predictive performance of different bleeding risk scores.
Results
BARC class ≥2 bleedings occurred in 36 patients (3.9%), while BARC class ≥3 bleedings were seen in 134 patients (14.4%). The HAS-BLED, ORBIT, ARTIA, PARIS, and PRECISE-DEAPT score were significantly associated with incidences of BARC class ≥2 and ≥3 bleedings during 1-year follow-up (all p<0.05). The ROC analysis showed that the predictive performance of the five bleeding risk scores for BARC class ≥3 bleedings were low-to-moderate [c-statistic: HASBLED 0.584 (0.552–0.616), ATRIA 0.624 (0.592–0.655), ORBIT 0.623 (0.591–0.654), PARIS 0.633 (0.601–0.664), PRECISEDAPT 0.616 (0.584–0.647)]. Multivariable logistic regression indicated that previous bleeding history and hemoglobin were independent predictors of BARC class ≥3 bleedings. Compared to the HAS-BLED score, the model constructed by previous bleeding history and hemoglobin displays a significant improvement in bleeding risk prediction (0.704 vs. 0.584, p=0.013).
Conclusions
In patients with AF and ACS/PCI receiving both anticoagulant and antiplatelet therapy, the HAS-BLED, ORBIT, ARTIA, PARIS, and PRECISE-DEAPT score displayed low-to-moderate performance for predicting BARC class ≥3 bleedings during 1-year follow-up. More accurate scoring systems for bleeding risk evaluation should be developed for these patients in the future.

Abstract
Abstract
Background
This study aimed to evaluate the association between plasma big endothelin-1 (ET-1) level and the severity of coronary artery disease assessed by the SYNTAX score (SS) in patient with non-ST segment-elevated myocardial infarction (NSTEMI).
Methods
A total of 766 patients with NSTEMI undergoing coronary angiography were recruited. Patients were divided into divided into three groups: low SS (SS ≤22), intermediate SS (23–32) and high SS group (SS >32). Spearman correlation, smooth curve fitting, logistic regression and Receiver operating characteristic (ROC) curve analysis were performed to evaluated the association between plasma big ET-1 level and the SS.
Results
There was a significant correlation between the big ET-1 and the SS (r=0.378, p<0.001). Smoothing curve indicated a positive correlation between plasma big ET-1 level and the SS, after adjustment for potential confounders. The ROC curve analysis showed that the area under the curve was 0.695 (0.661–0.727) and the optimal cutoff of plasma big ET-1 level were 0.35pmol/l, with a sensitivity of 68.9% and a specificity of 62.9%. Logistic regression showed that elevated big ET-1 was an independent predictor of intermediate-high SS in patients with NSTEMI, no matter entered as a continuous variable [OR (95% CI): 1.110 (1.053–1.170), p<0.001] or as a categorical variable [OR (95% CI): 2.873 (2.016–4.094), p<0.001]. The association between big ET-1 and intermediate-high SS was consistent across subgroups without significant interactions.
Conclusion
In patients presenting with NSTEMI, plasma big ET-1 level was significantly correlated with the SS. Elevated plasma big ET-1 level was an independent predictor for intermediate-high SS.

Abstract
Abstract
Objective
The Global Registry of Acute Coronary Events (GRACE) score is recommended for risk stratification for patients with ST-segment elevation myocardial infarction (STEMI) by clinical guidelines. Data about comorbidities were not incorporated in the GRACE score. This study aimed to evaluate the incremental predictive value of adding the CHA2DS2-VASc score to the GRACE score for in-hospital mortality in patients with STEMI.
Methods
7476 patients with STEMI were recruited and divided into five groups according to the CHA2DS2-VASc score (1, 2, 3, 4 and ≥5 points) at admission. The primary outcome was defined as in-hospital mortality, while the secondary outcomes were recurrent MI, stroke and major adverse cardiovascular events (MACE) during hospitalization. Univariate and multivariate logistic regression were performed to evaluate the association between the CHA2DS2-VASc score and outcomes. Incremental predictive performance of adding the CHA2DS2-VASc score to the GRACE score were evaluated through analysis of the receiver operating characteristic (ROC) curves, net reclassification improvement (NRI) and integrated discrimination improvement (IDI).
Results
With the increase of CHA2DS2-VASc score, patients with STEMI tended to have more comorbidities, receive less evidence-based treatments and carry worse in-hospital outcomes. Multivariate logistic regressions demonstrated that the CHA2DS2-VASc score was an independent predictor for in-hospital mortality [OR (95% CI): 1.320 (1.238–1.407), p<0.001], recurrent myocardial infarction [OR (95% CI): 1.233 (1.086–1.401), p=0.001], stroke [OR (95% CI): 1.433 (1.207–1.702), p<0.001] and MACE [OR (95% CI): 1.146 (1.088–1.207), p<0.001]. The c statistic value of combining the GRACE score with the CHA2DS2-VASc score was significantly higher than that of the GRACE score alone in predicting in-hospital mortality (0.784, 95% CI: 0.774–0.793 vs. 0.769, 95% CI: 0.760–0.779, z=4.180, p<0.001). The addition of the CHA2DS2-VASc score to the GRACE score resulted in significantly improved predictive performance for in-hospital mortality, with a NRI of 0.356 (95% CI: 0.280–0.432, p<0.001) and a IDI of 0.013 (95% CI: 0.009–0.018, p<0.001).
Conclusion
The CHA2DS2-VASc score was an independent predictor of in-hospital outcomes in patients with STEMI. Compared to the GRACE score alone, the addition of the CHA2DS2-VASc score to the GRACE score improved the predictive performance for in-hospital mortality in patients STEMI.

Abstract
Purpose: Androgen receptor-independent prostate cancers do not respond to androgen blockage therapies and suffer from high recurrence rate. We aim to contribute to the establishment of novel therapeutic approaches against such malignancies. Materials and Methods: We examined whether and how cold atmospheric plasma delivers selectivity against AR-independent prostate cancers via cell viability, transwell assay, wound healing, cell apoptosis assay, flow cytometry, intracellular hydrogen peroxide determination assay, RONS scavenger assay and western blot using human normal epithelial prostatic cells PNT1A and AR-negative DU145 prostate cancer cells. Results: We show that cold atmospheric plasma could selectively halt cell proliferation and migration in androgen receptor-independent cells as a result of induced cell apoptosis and G0/G1 stage cell cycle arrest, and such outcomes were achieved through modulations on the MAPK and NF-kB pathways in response to physical plasma induced intracellular redox level. Conclusion: Our study reports cold atmospheric plasma induced reduction on the proliferation and migration of androgen receptor-independent prostate cancer cells that offers novel therapeutic insights on the treatment of such cancers, and provides the first evidence on physical plasma induced cell cycle G0/G1 stage arrest that warrants the exploration on the synergistic use of cold atmospheric plasma and drugs such as chemotherapies in eradicating such cancer cells.

Methods: The prospective controlled research method was used. From September 2016 to January 2020, 16 patients aged 18-69 years, with extensive deep burns, including 9 males and 7 females, who met the selection criteria were admitted to the Department of Burns and Plastic Surgery of the 909th Hospital of the Joint Logistic Support Force of PLA. The bilateral limbs with similar injury in 8 patients were divided into Meek skin grafting+PRP group and Meek skin grafting alone group according to the random number table; in the other 8 patients, the limbs with severer injury were included in Meek skin grafting+PRP group, and the limbs on the other side were included in Meek skin grafting alone group. The wounds of affected limbs in the two groups were treated correspondingly. On post surgery day (PSD) 10, the survival and fusion of Meek microskin grafts were observed and the survival rate and fusion rate were calculated; the histological morphology and the angiogenesis of the basal tissue of Meek microskin graft were observed by hematoxylin-eosin staining and immunohistochemical staining, respectively, with the microvessels being counted. Data were statistically analyzed with paired sample t test. Results: On PSD 10, the wounds of affected limbs in Meek skin grafting+PRP group were dry, and most of the transplanted skin grafts were closely adhered to the basal tissue; while a small amount of exudate could be found in the wounds of affected limbs in Meek skin grafting alone group, and a small part of the transplanted microskin grafts fell off or poorly attached to the basal tissue. On PSD 10, the survival rate and the fusion rate of Meek microskin grafts in the wounds of affected limbs in Meek skin grafting+PRP group were (94±3)% and (86±4)%, which were significantly higher than (89±4)% and (79±4)% of Meek skin grafting alone group, respectively (t=3.633, 4.229, P<0.01). On PSD 10, the basal epidermis was closely connected with dermis of Meek microskin grafts in the wounds of affected limbs in Meek skin grafting+PRP group, with more inflammatory cell infiltration and active microvascular hyperplasia, while the basal epidermis was less closely connected with dermis of Meek microskin grafts in the wounds of affected limbs in Meek skin grafting alone group, with obvious degeneration of collagen fibers under the dermis, less inflammatory cell infiltration, and slightly poor microvascular hyperplasia. On PSD 10, the distribution of microvessels in basal tissue of Meek microskin grafts in the wounds of affected limbs in Meek skin grafting+PRP group were densely clustered, while the distribution of microvessels in Meek skin grafting alone group were scattered, sparse, and dotted. On PSD 10, the number of microvessels in basal tissue of Meek microskin grafts in the wounds of affected limbs in Meek skin grafting+PRP group was 36±6 in each 400-fold visual field, which was significantly more than 29±7 of Meek skin grafting alone group (t=2.671, P<0.05). Conclusions: Autologous PRP can effectively promote the survival rate and fusion rate of Meek microskin grafts in the wounds of limbs after escharectomy in severely burned patients by promoting angiogenesis at the base of Meek microskin grafts.

Abstract
BACKGROUND: Gabapentin and baclofen are recommended for the treatment of chronic refractory cough (CRC). We investigated the efficacy of flupentixol/melitracen in patients unresponsive to these neuromodulators.METHODS: A total of 101 patients with CRC who failed to respond to gabapentin and baclofen were recruited, and treated with flupentixol/melitracen. The prevalence of cough resolution and changes in the Cough Symptom Score (CSS), cough thresholds to capsaicin, Hull Airway Reflux Questionnaire (HARQ), Leicester Cough Questionnaire (LCQ), Generalized Anxiety Disorder-7, Hamilton Anxiety Rating Scale, Patient Health Questionnaire-9, and Hamilton Depression Rating Scale-24 were evaluated after treatment.RESULTS: Ninety-eight patients (97.0%) completed the study. The overall successful cough resolution rate was 62.4% (63/101). Cough resolution was accompanied by an obvious decrease in the CSS and HARQ score and a remarkable increase in cough thresholds to capsaicin challenge and LCQ score, whereas anxiety and depression scores did not change significantly. The prevalence of adverse effects (e.g., insomnia and dizziness) was 21.8%. The prevalence of cough recurrence within 2 weeks after treatment cessation was 17.8%.CONCLUSION: Flupentixol/melitracen may be an efficacious option for CRC unresponsive to other neuromodulators.

Abstract
OBJECTIVE To investigate the changes of CaM-CaMK-CREB signaling pathway and related neuron factors in hippocampus of rats after sevoflurane and propofol administration. MATERIALS AND METHODS A total of 90 SD rats, half male and half female, were selected. They were randomized into anesthesia group (AG) and control group (CG), in which 30 rats under propofol anesthesia in the AG were included in group A, 30 rats under sevoflurane anesthesia were included in group B, and 30 rats under mixed ventilation of air and oxygen were included in the CG. Before (10 rats were killed in each group) and at the end of anesthesia (2 weeks of anesthesia and 7 days of Morris water maze test), rats were respectively killed and then an appropriate amount of hippocampus was separated. Human tumor necrosis factor-alpha (TNF-α), vascular endothelial growth factor (VEGF), calmodulin (CaM), calmodulin-dependent kinase Ⅱ a (CaMK II a), NMDA receptor 2B (NR2B), cysteine aspartate specific protease-3 mRNA (Caspase-3mRNA) and protein contents were detected. RESULTS The latency of rats in group A and group B, as well as their times of crossing the original platform on 1, 4, and 7d were markedly higher than those of the CG, and those in group B were markedly lower than those in group A (p<0.001). The total distance of rats in group A and group B on 1, 4, and 7d was significantly higher than that of the CG, and that in group B was dramatically lower than that in group A (p<0.001). The speed of rats in the three groups ranged from 1d to 7d, and there was no significant difference at different time points (p>0.05). At the end of anesthesia, the expression levels of CaM mRNA and protein in hippocampus of rats in group A and group B were remarkably higher than those of the CG, and those of CaMK II a mRNA and protein were remarkably lower than those of the CG; the CaM mRNA and protein expression levels in hippocampus of group A were significantly higher than those of group B, and those of CaMK IL a mRNA and protein were significantly lower than those of group B (p<0.001). Simultaneously, the expression levels of NR2BmRNA, Caspase-3mRNA and protein in hippocampus of group A and group B were substantially higher than those of the CG, and those in group B were substantially lower than those in group A (p<0.001). What's more, the TNF-a and VEGF expression levels in hippocampus of group A and B were markedly higher than those of the CG, and those in group B were dramatically lower than those of group A (p<0.001). CONCLUSIONS Sevoflurane anesthesia on the CaM-CaMK-CREB signaling pathway and learning and memory function of rats is less volatile, which does better in safeguarding stability.

Abstract
OBJECTIVE Postpartum hemorrhage (PPH) is a major cause of maternal mortality and morbidity worldwide. The purpose of this study was to evaluate if meconium-stained amniotic fluid (MSAF) is a risk factor for PPH after vaginal delivery. PATIENTS AND METHODS We retrospectively analyzed medical records of all patients who had a vaginal delivery at Fujian Provincial Maternity and Children's Hospital, between 1st January 2013 to 31st December 2018. Women with cesarean deliveries, multiple pregnancies, abnormal coagulation profile, and those with concomitant liver or kidney disorders were excluded. Patients were classified into MSAF (n=13686) and clear amniotic fluid (AF) (n=41511) groups. RESULTS The incidence of PPH was significantly higher at 2.7% (370/13686) in the MSAF group as compared to 2.18% (904/41511) in the clear AF group (p=0.0004). There was no difference in the incidence of severe PPH between the two groups. Statistically significant difference in the incidence of PPH between MSAF and clear AF was seen in the maternal age groups of 30-34 and 35-39 years, gestational age>40weeks and >3 gravidity (p<0.05). CONCLUSIONS Our study demonstrates that MSAF is a significant risk factor for minor and moderate PPH. Presence of meconium could therefore alert clinicians to expect PPH and make arrangements for further patient management. Further basic research is required to evaluate the mechanism by which meconium influences the incidence of PPH.

Abstract
OBJECTIVE To assess the effects of curcumol on the proliferation, apoptosis and collagen synthesis of keloid fibroblasts and explore the underlying mechanism. OBJECTIVE Keloid fibroblasts were treated with different concentrations of curcumol (10, 20, 40, 80 and 160 mg/L) or with 160 mg/L curcumol and 20 μmol/L ISO (an ERK signaling pathway activator). Western blotting was performed to detect the expression levels of proliferation-associated proteins (cyclin D1 and PCNA), fibrosis marker proteins (Col1A1, Col3A1 and α-SMA), apoptosis proteins (Bcl-2, Bax and cleaved caspase-3) and ERK signaling pathway proteins (p-ERK1/2, p-MEK and p-c-Raf) in the cells. MTT assay and flow cytometry were used to evaluate the proliferation and apoptosis rate of the treated cells, respectively. OBJECTIVE Curcumol at 10, 20, 40, 80 and 160 mg/L all reduced the protein expressions of cyclin D1, PCNA and Bcl-2, inhibited the expressions of fibrotic marker proteins Col1A1, Col3A1 and α-SMA, decreased the levels of ERK signaling pathway proteins p-ERK1/2, p-MEK and p-c-Raf, and increased the expressions of Bax and cleaved caspase-3 proteins (P < 0.05). Curcumol treatment at 160 mg/L obviously inhibited the proliferation and collagen synthesis, promoted cell apoptosis and inhibited the ERK signaling pathway in the keloid fibroblasts; treatment with ISO significantly reversed the effects of curcumol on the proliferation, apoptosis, collagen synthesis and ERK signal pathway of the cells. OBJECTIVE Curcumol regulates proliferation, apoptosis and collagen synthesis in keloid fibroblasts through the ERK signaling pathway.

Abstract
OBJECTIVES Organ failure (OF), a leading cause of death in HIV-positive individuals, is common in patients undergoing liver transplantation (LT). We examined the impact of HIV infection on pre- and post-LT mortalities in cirrhotic patients stratified by the number and type of OFs. METHODS We performed a cross-sectional study and a retrospective cohort study using the US National Inpatient Sample (NIS) and the United Network for Organ Sharing (UNOS) registry data, respectively. Patients who had not yet undergone LT from the NIS database (2010-2014) and patients undergoing LT from the UNOS database (2003-2016) were included in the study. RESULTS Analysis of patients (201 348) from the NIS database showed that one [adjusted odds ratio (aOR) 1.531; 95% confidence interval (CI) 1.160-2.023], two (aOR 1.624; 95% CI 1.266-2.083) or three or more OFs (aOR 1.349; 95% CI 1.165-1.562) were associated with higher pre-LT mortality in HIV-infected patients compared with HIV-negative patients with the corresponding number of OFs. In patients without OF, HIV infection was not associated with increased pre-LT mortality. UNOS data for patients undergoing LT (38 942) showed that the presence of two or more OFs was associated with increased post-LT 1-year mortality in HIV-infected patients compared with non-HIV-infected patients with the corresponding number of OFs (aOR 2.342; 95% CI 1.576-3.480). However, in patients with no OF or only one OF, HIV infection was not associated with increased post-LT 1-year mortality (aOR 1.372; 95% CI 0.911-2.068). CONCLUSIONS The results of this study emphasize the importance of preventing OF development, and justify LT for HIV-infected patients with no or only one OF.

Abstract
OBJECTIVE Long non-coding RNA LINC00173 (LINC00173) has been shown to facilitate the progression of a number of malignancies. In this study, we aimed to investigate the function of LINC00173 on prostate cancer (PCa) and discover the potential regulatory mechanism. PATIENTS AND METHODS RT-PCR was used to determine the levels of LINC00173, miR-338-3p and Rab25 in PCa patients and cell lines. The clinical significance of LINC00173 was statistically analyzed in 124 PCa patients. CCK-8, colony formation, transwell, scratch wound, Ethynyldeoxyuridine (EdU) assays and flow cytometry assays were used to detect the proliferation, apoptosis, invasion and migration of PCa cells. The mechanism of LINC00173 action was explored through bioinformatics, RNA pull-down assays and Luciferase reporter assays. RESULTS We observed that the expression of LINC00173 and Rab25 was distinctly upregulated in both PCa specimens and cell lines, while miR-338-3p expression was significantly down-regulated. High LINC00173 expression was associated with Gleason score, preoperative PSA level and reduced patient survivals. Functional assays revealed that knockdown of LINC00173 suppressed the proliferation, migration and invasion of PCa cells, and promoted apoptosis. Mechanistically, LINC00173 acted as a competitive endogenous RNA in PCa and increased Rab25 expressions via sponging miR-338-3p. Moreover, LINC00173 promoted PCa progression by interacting with miR-338-3p and Rab25. CONCLUSIONS Our findings, for the first time, identified a novel PCa-related lncRNA, LINC00173 which might serve as an oncogene in PCa. The discovery of the LINC00173/miR-338-3p/Rab25 pathways provided new thinking for the treatments of PCa.

Abstract
OBJECTIVE To identify laboratory markers among platelet indices, coagulation parameters, blood lipid parameters, and liver/kidney function variables that can be used to predict preeclampsia. PATIENTS AND METHODS We studied records of 568 women with preeclampsia, gestational hypertension (GH), or normal term pregnancies hospitalized in the Obstetrics Department of the Fujian Maternal and Child Health Hospital from September 2014 to September 2018. We divided the patients' records into three groups (216 with preeclampsia, 136 with gestational hypertension, and 216 with normal pregnancies). We conducted retrospective analyses to compare variable measurements between the groups and find correlations. We looked into maternal pre-onset platelet indices, coagulation parameters (thrombin time [TT], fibrinogen [FIB]), biochemical parameters (total cholesterol [TC], triglycerides [TG], high-density lipoproteins [HDL], alanine transaminase [ALT], serum creatinine [CRE], blood urea nitrogen [BUN], uric acid [UA]), maternal complications, and perinatal outcomes. In addition to our statistical analysis, we trained a back-propagation (BP) neural network to identify the strongest predictors of preeclampsia. RESULTS We found significant differences among the groups in terms of values for PLT, MPV, PDW, PLCR, TT, FIB, TG, LDH, BUN, and others. After adjusting for confounding factors in a multivariate ordered logistic regression model, we found that mean values for MPV, BUN, TG, and LDH can independently predict the risk of preeclampsia (the OR values were 1.858, 1.583, 1.104, and 1.020, respectively), the C-index (concordance statistic) was 0.73. Also, our BP neural network derived ALB, MPV, BUN, LDH and TG as the strongest predictors of preeclampsia. CONCLUSIONS MPV, TG, LDH, and BUN can help establish the risk for the development of preeclampsia to apply active measures and improve maternal and perinatal outcomes. The BP neural network can be used to study predictive models of preeclampsia.

Abstract
Background SNRPD1 is a spliceosome-associated protein and has previously been implicated with important roles in cancer development. Methods Through analyzing the differential expression patterns and clinical association of splicing associated genes among tumor and tumor adjacent samples across different tumors and among different breast cancer subtypes, we identify the tumor promotive role of SNRPD1 using multiple publicly available datasets. Through pathway, gene ontology enrichment analysis and network construction, we linked the onco-therapeutic role of SNRPD1 with cell cycle. Via a series of experimental studies including knockdown assay, qPCR, western blotting, cell cycle, drug response assay, we confirmed the higher expression of SNPRD1 at both gene and protein expression levels in triple negative breast cancer cells, as well as its roles in promoting cell cycle and chemotherapy response. Results Our study revealed that SNRPD1 over-expression was significantly associated with genes involved in cell cycle, cell mitosis and chromatin replication, and silencing SNRPD1 in breast cancer cells could lead to halted tumor cell growth and cell cycle arrest at the G0/G1 stage. We also found that triple negative breast cancer cells with reduced SNRPD1 expression lost certain sensitivity to doxorubicin whereas luminal cancer cells did not. Conclusions Our results suggested the prognostic value of SNRPD1 on breast cancer survival, its potential as the therapeutic target halting cell cycle progression for breast cancer control, and warranted special attention on the combined use of doxorubicin and drugs targeting SNRPD1.

Abstract
OBJECTIVE To investigate the mechanism of the antidepressant-like effects of Chaihu Guizhi decoction (CGD). OBJECTIVE Chaihu Guizhi decoction at the daily dose of 17 g/kg and solvent vehicle were administered by gavage in 12 and 14 male C57BL/6J mice for 7 consecutive days, respectively. Forced swimming test (FST), elevated plus maze (EPM) test, open field test (OFT) and novelty-suppressed feeding test (NSF) were performed to assess the depression- and anxiety-like behaviors and motor ability of the mice. We further used chronic social defeat stress (CSDS) and social interaction test to evaluate the antidepressant-like effects of CGD in comparison with the solvent vehicle. Western blotting and RT-qPCR were performed to detect the expressions of sirt1, p53, acetylated p53, and the neuron plasticity-related genes including synapsin I (Syn1), Rab4B, SNAP25 and tubulin beta4b in the hippocampus of the mice. OBJECTIVE In FST, the immobility time of CGDtreated mice was decreased significantly (P < 0.05); no significant differences were found in the performances in EPM, NSF and OFT tests between the two groups. In social interaction test, the mouse models of CSDS treated with CGD showed significantly increased time in the interaction zone (P < 0.05). Compared with those in the vehicle group, the CGD-treated mouse models exhibited significantly increased protein level of SIRT1 and decreased p53 acetylation (P < 0.05) with up-regulated synapsin I mRNA expression in the hippocampus (P < 0.05); no significant difference were found in Rab (P=0.813), SNAP (P=0.820), or Tubb mRNA expressions (P=0.864) between the two groups. OBJECTIVE CGD produces antidepressant-like effects in mice possibly through the sirt1-p53 signaling pathway and synaptic plasticity.

Abstract
BACKGROUND Oral and maxillofacial surgery currently relies on virtual surgery planning based on image data (CT, MRI). Three-dimensional (3D) visualizations are typically used to plan and predict the outcome of complex surgical procedures. To translate the virtual surgical plan to the operating room, it is either converted into physical 3D-printed guides or directly translated using real-time navigation systems. PURPOSE This study aims to improve the translation of the virtual surgery plan to a surgical procedure, such as oncologic or trauma surgery, in terms of accuracy and speed. Here we report an augmented reality visualization technique for image-guided surgery. It describes how surgeons can visualize and interact with the virtual surgery plan and navigation data while in the operating room. The user friendliness and usability is objectified by a formal user study that compared our augmented reality assisted technique to the gold standard setup of a perioperative navigation system (Brainlab). Moreover, accuracy of typical navigation tasks as reaching landmarks and following trajectories is compared. RESULTS Overall completion time of navigation tasks was 1.71 times faster using augmented reality (P = .034). Accuracy improved significantly using augmented reality (P < .001), for reaching physical landmarks a less strong correlation was found (P = .087). Although the participants were relatively unfamiliar with VR/AR (rated 2.25/5) and gesture-based interaction (rated 2/5), they reported that navigation tasks become easier to perform using augmented reality (difficulty Brainlab rated 3.25/5, HoloLens 2.4/5). CONCLUSION The proposed workflow can be used in a wide range of image-guided surgery procedures as an addition to existing verified image guidance systems. Results of this user study imply that our technique enables typical navigation tasks to be performed faster and more accurately compared to the current gold standard. In addition, qualitative feedback on our augmented reality assisted technique was more positive compared to the standard setup.?>.
