Abstract
The rare fungus Candida saopaulonensis has never been reported to be associated with human infection. We report the draft genome sequence of the first clinical isolate of C. saopaulonensis, which was isolated from a very premature infant with sepsis. This is the first genome assembly reaching the near-complete chromosomal level with structural annotation for this species, opening up avenues for exploring evolutionary patterns and genetic mechanisms of pathogenesis.

Abstract
PURPOSE To evaluate the accuracy and feasibility of robot-assisted cervical screw placement and factors that may affect the accuracy. METHODS A comprehensive search was made on PubMed, Embase, Cochrane Library, Web of Science, CNKI, and Wanfang Med for the selection of potential eligible literature. The outcomes were evaluated in terms of the relative risk (RR) or standardized mean difference (MD) and corresponding 95% confidence interval (CI). Subgroup analyses of the accuracy of screw placement at different cervical segments and with different screw placement approaches were performed. A comparison was made between robotic navigation and conventional freehand cervical screw placement. RESULTS Six comparative cohort studies and five case series studies with 337 patients and 1342 cervical screws were included in this study. The perfect accuracy was 86% (95% CI, 82-89%) and the clinically acceptable rate was 98% (95% CI, 95-99%) in robot-assisted cervical screw placement. The perfect accuracy of robot-assisted C1 lateral mass screw placement was the highest (96%), followed by C6-7 pedicle screw placement (93%) and C2 pedicle screw placement (86%), and the lowest was C3-5 pedicle screw placement (75%). The open approach had a higher perfect accuracy than the percutaneous/intermuscular approach (91% vs 83%). Compared with conventional freehand cervical screw placement, robot-assisted cervical screw placement had a higher accuracy, a lower incidence of perioperative complications, and less intraoperative blood loss. CONCLUSION With good collaboration between the operator and the robot, robot-assisted cervical screw placement is accurate and feasible. Robot-assisted cervical screw placement has a promising prospect.

Abstract
PURPOSE We investigated both the clinical utilities and the prognostic impacts of the clonotypic peptide mass spectrometry (MS)-EasyM, a blood-based minimal residual disease (MRD) monitoring protocol in multiple myeloma. EXPERIMENTAL DESIGN A total of 447 sequential serum samples from 56 patients with multiple myeloma were analyzed using EasyM. Patient-specific M-protein peptides were sequenced from diagnostic samples; sequential samples were quantified by EasyM to monitor the M-protein. The performance of EasyM was compared with serum immunofixation electrophoresis (IFE), bone marrow multiparameter flow cytometry (MFC), and next-generation flow cytometry (NGF) detection. The optimal balance of EasyM sensitivity/specificity versus NGF (10-5 sensitivity) was determined and the prognostic impact of MS-MRD status was investigated. RESULTS Of the 447 serum samples detected and measured by EasyM, 397, 126, and 92 had time-matching results for comparison with serum IFE, MFC-MRD, and NGF-MRD, respectively. Using a dotp >0.9 as the MS-MRD positive, sensitivity was 99.6% versus IFE and 100.0% versus MFC and NGF. Using an MS negative cutoff informed by ROC analysis (<1.86% of that at diagnosis), EasyM sensitivity remained high versus IFE (88.3%), MFC (85.1%), and NGF (93.2%), whereas specificity increased to 90.4%, 55.8%, and 93.2%, respectively. In the multivariate analysis, older diagnostic age was an independent predictor for progression-free survival [PFS; high risk (HR), 3.15; 1.26-7.86], the best MS-MRD status (MS-MRD negative) was independent predictor for both PFS (HR, 0.25; 0.12-0.52) and overall survival (HR, 0.16; 0.06-0.40). CONCLUSIONS EasyM is a highly sensitive and minimal invasive method of MRD monitoring in multiple myeloma; MS-MRD had significant predictive ability for survival outcomes.

Abstract
OBJECTIVES To develop a nomogram using pretreatment ultrasound (US) and contrast-enhanced ultrasound (CEUS) to predict the clinical response of neoadjuvant chemotherapy (NAC) in patients with borderline resectable pancreatic cancer (BRPC) or locally advanced pancreatic cancer (LAPC). METHODS A total of 111 patients with pancreatic ductal adenocarcinoma (PDAC) treated with NAC between October 2017 and February 2022 were retrospectively enrolled. The patients were randomly divided (7:3) into training and validation cohorts. The pretreatment US and CEUS features were reviewed. Univariate and multivariate logistic regression analyses were used to determine the independent predictors of clinical response in the training cohort. Then a prediction nomogram model based on the independent predictors was constructed. The area under the curve (AUC), calibration plot, C-index and decision curve analysis (DCA) were used to assess the nomogram's performance, calibration, discrimination and clinical benefit. RESULTS The multivariate logistic regression analysis showed that the taller-than-wide shape in the longitudinal plane (odds ratio [OR]:0.20, p = 0.01), time from injection of contrast agent to peak enhancement (OR:3.64; p = 0.05) and Peaktumor/ Peaknormal (OR:1.51; p = 0.03) were independent predictors of clinical response to NAC. The predictive nomogram developed based on the above imaging features showed AUCs were 0.852 and 0.854 in the primary and validation cohorts, respectively. Good calibration was achieved in the training datasets, with C-index of 0.852. DCA verified the clinical usefulness of the nomogram. CONCLUSIONS The nomogram based on pretreatment US and CEUS can effectively predict the clinical response of NAC in patients with BRPC and LAPC; it may help guide personalized treatment.

Abstract
SUMMARY Ear framework handcrafting simulation using costal cartilage models is crucially important for ear reconstruction surgery education. Fabrication of proper models that are mechanically and structurally comparable to their native counterparts is an unmet challenge. The authors developed structure and mechanical performance biomimetic costal cartilage models for practicing and simulating handcrafting of ear frameworks. High-tensile silicone and three-dimensional techniques were used to fabricate biomimetic models. The models well-replicated the three-dimensional structure of human costal cartilage. Comprehensive mechanical tests showed that high-tensile silicone models had stiffness, hardness, and suture retention ability similar to those of their native counterparts, and they were distinctly superior to commonly used materials for costal cartilage simulation. This model satisfied surgeons and contributed to creation of outstanding ear frameworks. The recreated models were used in ear framework handcrafting workshops. Novices' surgical simulation performance with different models was compared and analyzed. People who used high-tensile silicone models have greater progress and confidence after training. Using high-tensile silicone costal cartilage models is an excellent choice for practicing and simulating the fabrication of ear frameworks manually. The models benefit practitioners and students in practicing handcrafting ear frameworks and surgical skills.

Abstract
PURPOSE This study investigated the clinical and antimicrobial characteristics of Acinetobacter spp. bloodstream infection (BSI) in hematological patients. Risk factors for 30-day mortality and carbapenem-resistant Acinetobacter spp. (CRA) BSI acquisition were also identified. METHODS We reviewed forty hematological patients with Acinetobacter spp. BSI in a large Chinese blood disease hospital between 2013 and 2022. The remaining CRA isolates were subjected to whole-genome sequencing. RESULTS The 30-day mortality rate was high at 35%. Hematological patients with Acinetobacter spp. BSI often presented with severe conditions and co-infections at multiple sites. All strains were colistin-susceptible and 40.0% were CR. Multivariate analysis identified several risk factors associated with CRA BSI acquisition, including previous exposure to carbapenems within 30 days and CRA colonization. Very severe aplastic anaemia, tetracycline-resistant Acinetobacter spp. BSI, and unresolved neutropenia after infection were closely associated with 30-day mortality. Non-survivors often presented with higher median PCT and CRP levels and severe complications, such as intracranial infection, cardiac dysfunction, respiratory failure, and severe sepsis or septic shock. Our study also identified inappropriate empirical antibiotic therapy as an independent predictor of 30-day mortality (OR: 11.234, 95% CI: 1.261-20.086, P = 0.030). This study was the first to report A. oleivorans as a human pathogen, and to identify its unique oxacillinase, OXA-325. CONCLUSION An environment-originated non-pathogenic species can become pathogenic when the body's immunity is compromised. Our results also highlighted the importance of improving neutropenia after infection, treating severe organ dysfunction, and administering appropriate empirical antibiotic therapy to reduce mortality in this patient population.

Abstract
Purpose With an estimated prevalence of 38%, enteral feeding intolerance (EFI) is common in critically ill patients receiving enteral nutrition (EN), and is associated with higher mortality and longer duration of mechanical ventilation. Various methods have been reported to decrease the incidence of EFI during EN, such as post-pyloric feeding, continuous EN delivery, abdominal massage, and probiotic supplementation. However, several studies reported conflicting results. Inappropriate interventions may cause gastrointestinal (GI) injury. This study aims to design a protocol based on Mukbang videos, which are widely watched online, to detect their effects on the incidence of EFI, nutritional status, incidence of infectious complications, and activities of daily living. Patients and Methods We will conduct a three-arm, parallel-design, randomized controlled trial that will be implemented in 273 patients from intensive care units. Participants will be randomized into one of the three intervention arms (1:1:1), which will be performed by a research assistant. Participants were allocated to three groups: (a) watching mukbang video, (b) watching a cooking show, and (c) watching a non-food content video. Prior to EN initiation, each participant will watch a ten-minute mukbang video, cookery show, or non-food content video. Conclusion Mukbang videos show food, expressions of mukbangers and eating sounds. If it effectively reduces the incidence of EFI, leads to greater nutritional status, lower incidence of infectious complications, and a higher level of independence among patients compared with watching cooking videos or non-food content videos, it has broad dissemination potential as a non-invasive, easily assessing, and using method.

Abstract
Background The presence of mild deficit is the most common reason for nonuse of intravenous alteplase in ischemic stroke. We analyzed within a national prospective cohort on whether patients with minor stroke can benefit from intravenous alteplase. Methods This observational study included patients with acute ischemic stroke with a National Institutes of Health Stroke Scale (NIHSS) score 0 to 5 at admission. The short-term outcomes at discharge and 3-month were analyzed including the modified Rankin Scale score, gait speed, Montreal Cognitive Assessment, Patient Health Questionnaire-9, General Anxiety Disorder-7 and Stroke Impact Scale-16. Multivariate regression models were performed to evaluate the association between intravenous thrombolysis and clinical outcomes. Results A total of 1876 consecutive patients were included in the current analyses with 102 patients (5.4%) received alteplase and 1774 patients (94.5%) were in non-alteplase group. We found that 10.9% patients presented unfavorable functional outcome with a mRS ≥ 2 at 3-month. Patients with alteplase treatment had a more favorable outcome in SIS-16 at discharge (OR, 5.45; 95% CI, 2.22-8.68) and 3-month after stroke (OR, 2.34; 95% CI, 0.17-4.50). There was an association of alteplase with better gait speed in the restricted sample of age >60 (OR,0.14; 95% CI, 0.02-0.25), while an unfavorable effect was found in anxiety (OR, 2.23; 95% CI, 2.23, 0.91-3.55) and depression (OR, 1.54; 95% CI, 0.17-2.91) in female. Conclusion Alteplase showed a suggestive benefit in function and motor outcomes in patients with low NIHSS score of 0-5. Meanwhile, female seemed more inclined to post-stroke emotional problems after alteplase treatment, which should be further explored in the future.

Abstract
PURPOSE Bloodstream infection (BSI) caused by Carbapenem-Resistant Enterobacteriaceae (CRE) are associated with poor outcomes in hematological patients. The aim of this study was to identify risk factors for mortality and evaluate the value of epidemiological feature of carbapenemases in guiding antimicrobial treatment options. METHODS Hematological patients with monomicrobial CRE BSI between January 2012 and April 2021 were included. The primary outcome was all-cause mortality 30 days after BSI onset. RESULTS A total of 94 patients were documented in the study period. Escherichia coli was the most common Enterobacteriaceae, followed by Klebsiella pneumoniae. 66 CRE strains were tested for carbapenemase genes, and 81.8% (54/66) were positive, including NDM (36/54), KPC (16/54), IMP (1/54). Besides, one E. coli isolate was found to express both NDM and OXA-48-like genes. Overall, 28 patients received an antimicrobial treatment containing ceftazidime-avibactam (CAZ-AVI), of which 21 cases were combined with aztreonam. The remaining 66 patients were treated with other active antibiotics (OAAs). The 30-day mortality rate was 28.7% (27/94) for all patients, and was only 7.1% ((2/28) for patients treated with CAZ-AVI. In multivariate analysis, the presence of septic shock at BSI onset (OR 10.526, 95% CI 1.376-76.923) and pulmonary infection (OR 6.289, 95% CI 1.351-29.412) were independently risk factors for 30-day mortality. Comparing different antimicrobial regimens, CAZ-AVI showed a significant survive benefit than OAAs (OR 0.068, 95% CI 0.007-0.651). CONCLUSION CAZ-AVI-containing regimen is superior to OAAs for CRE BSI. As the predominance of blaNDM in our center, we recommend the combination with aztreonam when choose CAZ-AVI.

Abstract
BACKGROUND In most areas of China, mothers typically do not participate in early care of preterm infants in NICU. This study aims to examine the early experience of mothers of preterm infants participating in skin-to-skin contact combined with non-nutritive comfort sucking in China. METHODS This qualitative research study used one-on-one, face-to-face, semi-structured in-depth interviews. Eighteen mothers who participated in early skin-to-skin contact combined with non-nutritive comfort sucking were interviewed in the NICU of a tertiary children's hospital in Shanghai between July and December 2020. Their experiences were analyzed using the inductive topic analysis method. RESULTS Five themes about skin-to-skin contact combined with non-nutritive comfort sucking were identified, including alleviation of maternal anxiety and fear during mother infant separation, reshaping the maternal role, promotion of active breast pumping, enhances the mother's willingness to actively breast feed and building the maternal confidence in baby care. CONCLUSION Skin-to-skin contact combined with non-nutritive comfort sucking in the NICU can not only enhance the identity and responsibility of the mother's role, but also provide non-nutritive sucking experience for promoting the establishment of oral feeding in preterm infants.

Abstract
Gynostemma is an important medicinal and food plant of the Cucurbitaceae family. The phylogenetic position of the genus Gynostemma in the Cucurbitaceae family has been determined by morphology and phylogenetics, but the evolutionary relationships within the genus Gynostemma remain to be explored. The chloroplast genomes of seven species of the genus Gynostemma were sequenced and annotated, of which the genomes of Gynostemma simplicifolium, Gynostemma guangxiense and Gynostemma laxum were sequenced and annotated for the first time. The chloroplast genomes ranged from 157,419 bp (Gynostemma compressum) to 157,840 bp (G. simplicifolium) in length, including 133 identical genes: 87 protein-coding genes, 37 tRNA genes, eight rRNA genes and one pseudogene. Phylogenetic analysis showed that the genus Gynostemma is divided into three primary taxonomic clusters, which differs from the traditional morphological classification of the genus Gynostemma into the subgenus Gynostemma and Trirostellum. The highly variable regions of atpH-atpL, rpl32-trnL, and ccsA-ndhD, the repeat unilts of AAG/CTT and ATC/ATG in simple sequence repeats (SSRs) and the length of overlapping regions between rps19 and inverted repeats(IRb) and between ycf1 and small single-copy (SSC) were found to be consistent with the phylogeny. Observations of fruit morphology of the genus Gynostemma revealed that transitional state species have independent morphological characteristics, such as oblate fruit and inferior ovaries. In conclusion, both molecular and morphological results showed consistency with those of phylogenetic analysis.

Abstract
Purpose To investigate the effectiveness of dysphagia screening and subsequent swallowing rehabilitation in elderly stroke patients with malnutrition risk. Patients and Methods Based on the Chinese Stroke Center Alliance (CSCA) from August 1, 2015 to July 21, 2019, we compared the in-hospital adverse outcomes among stroke patients (including ischemic stroke, intracranial hemorrhage, and subarachnoid hemorrhage) over 70 years old with and without dysphagia screening. The primary outcome was in-hospital all-cause mortality. Secondary outcomes were the composite endpoint of discharge against medical advice (DAMA) or in-hospital death. Results Among 365,530 stroke patients ≥ 70 years old with malnutrition risk in the CSCA, documented dysphagia screening was performed for 288,764 (79.0%) participants. Of these, 41,482 (14.37%) patients had dysphagia, and 33,548 (80.87%) patients received swallowing rehabilitation. A total of 1,694 (0.46%) patients experienced in-hospital death. After adjustment for traditional risk factors, dysphagia screening was associated with a low risk of all-cause mortality in stroke patients [adjusted odds ratio (aOR): 0.75, 95% confidence interval (CI):0.65–0.87]. Compared to patients with dysphagia who did not receive swallowing rehabilitation, patients reveiving swallowing rehabilitation had a reduced risk of in-hospital death (aOR:0.39, 95% CI: 0.33–0.46). Additionally, dysphagia screening had a lower risk for the composite endpoint of DAMA or in-hospital death (aOR:0.83,95% CI: 0.80–0.87), as did subsequent swallowing rehabilitation (aOR:0.43,95% CI: 0.40–0.47). Similar results were observed in the sensitivity analysis through inverse probability of treatment weighting, propensity score matching, and excluding patients without National Institutes of Health Stroke Scale scores. A similar association was observed between dysphagia management and adverse clinical outcomes in ischemic stroke and intracranial hemorrhage patients. Conclusion Dysphagia screening and swallowing rehabilitation were associated with a reduced risk of in-hospital death and composite outcome of DAMA or in-hospital death for stroke patients with malnutrition risk. Future research should concentrate on improving the quality of medical care for dysphagia management to improve patients’ outcomes.

Abstract
BACKGROUND Bladder cancer (BCA) is the most common urinary tumor, but its pathogenesis is unclear, and the associated treatment strategy has rarely been updated. In recent years, a deeper understanding of tumor epigenetics has been gained, providing new opportunities for cancer detection and treatment. METHODS We identified prognostic methylation sites based on DNA methylation profiles of BCA in the TCGA database and constructed a specific prognostic subgroup. RESULTS Based on the consistent clustering of 402 CpGs, we identified seven subgroups that had a significant association with survival. The difference in DNA methylation levels was related to T stage, N stage, M stage, grade, sex, age, stage and prognosis. Finally, the prediction model was constructed using a Cox regression model and verified using the test dataset; the prognosis was consistent with that of the training set. CONCLUSIONS The classification based on DNA methylation is closely related to the clinicopathological characteristics of BCA and determines the prognostic value of each epigenetic subtype. Therefore, our findings provide a basis for the development of DNA methylation subtype-specific therapeutic strategies for human bladder cancer.
