Single cell analysis reveals that SPP1 macrophages enhance tumor progression by triggering fibroblast extracellular vesicles.

Patients with liver metastatic colorectal cancer (mCRC) have a poor prognosis and are the leading cause of death in colorectal cancer (CRC) patients, but the mechanisms associated with CRC metastasis have not been fully elucidated. In this study, we obtained data from the Gene Expression Omnibus database and characterized the single-cell profiles of CRC, mCRC and healthy samples at single-cell resolution, and explored the cells that influence CRC metastasis. We find that AQP1 CRC identified as highly malignant tumor cells exhibited proliferative and metastatic characteristics.

NSTEMI Risk Prediction with the Combination of the Biomarkers Epicardial Adipose Tissue and Soluble Suppression of Tumorigenicity 2.

BACKGROUND Epicardial adipose tissue (EAT) and soluble suppression of tumorigenicity 2 (sST2) are valuable markers of myocardial fibrosis, but the relationship between EAT and sST2 remains controversial. This study aimed to evaluate the role of combined EAT measurements and levels of sST2 and the risk of major adverse cardiovascular events (MACEs) in patients with diagnosis of non-ST-elevation myocardial infarction (NSTEMI). MATERIAL AND METHODS This was a single-center retrospective observational study.

Lymphocyte to c-reactive protein ratio predicts the risk of contrast-induced acute kidney injury in STEMI patients undergoing percutaneous coronary intervention.

Background: Contrast-induced acute kidney injury (CI-AKI) is a common complication of percutaneous coronary intervention (PCI) in ST-elevation myocardial infarction (STEMI) patients. Our aim was to assess the lymphocyte to C-reactive protein ratio (LCR) to predict CI-AKI in patients with acute STEMI.

Methods: A total of 777 patients with STEMI undergoing primary PCI were continuously included in this study.

Gut microbial-derived N-acetylmuramic acid alleviates colorectal cancer via the AKT1 pathway.

Methods: Through single-cell RNA sequencing, a unique ONECUT2TFPI GC cell subset was identified in the oxaliplatin-resistant TME.

Combination of Epicardial Adipose Tissue and Left Atrial Low-Voltage Areas Predicting Atrial Fibrillation Recurrence after Radiofrequency Ablation.

Introduction: Atrial fibrillation (AF) is a common arrhythmia, with radiofrequency catheter ablation (RFCA) being first-line therapy. However, the high rate of post-ablation recurrence necessitates the identification of predictors for recurrence risk. Left atrial low-voltage areas (LA-LVASs), reflecting atrial fibrosis, have been confirmed to be related to recurrence of AF.

Association of Patient-Reported Outcomes Measurement Information System Measures With Injection and Surgical Treatment Response in Patients With De Quervain Tenosynovitis.

Purpose: Treatment of de Quervain tenosynovitis is largely empiric. Patient-Reported Outcomes Management Information System (PROMIS) scores at the time of diagnosis might provide insights into the probability of success of nonsurgical management and predict the necessity for surgical treatment. We aimed to identify which, if any, of the PROMIS metrics may be used to identify patients who will opt for surgery or be managed with injection alone.

External Fixation Prior to Fasciectomy Leads to Substantial Improvement of Advanced Dupuytren's PIP Contractures at Mean Follow-up 15 Months.

Background: The Digit Widget is an external fixation device that can be used to reverse proximal interphalangeal joint (PIPJ) contractures in the hand. Our hypothesis is that usage of the Digit Widget prior to fasciectomy in patients with severe Dupuytren's proximal interphalangeal (PIP) contractures will result in short-term improvement and maintenance of the PIPJ contracture after fasciectomy.

Methods: Patients who underwent placement of the Digit Widget soft tissue distractor prior to fasciectomy for Dupuytren's disease were identified between January 2015 and December 2018.

The predictive value of left atrium epicardial adipose tissue on recurrence after catheter ablation in patients with different types of atrial fibrillation.

Background: A growing body of evidence supports that the left atrium epicardial adipose tissue (LA-EAT) is related to the occurrence and recurrence of atrial fibrillation (AF). The relationship between LA-EAT and the recurrence after radiofrequency catheter ablation (RFCA) in patients with different types of AF is still unclear. This study aims to evaluate the predictive value of LA-EAT on the recurrence of AF after RFCA in patients with different types of AF.

Predicting the Postmortem Interval Based on Gravesoil Microbiome Data and a Random Forest Model.

The estimation of a postmortem interval (PMI) is particularly important for forensic investigations. The aim of this study was to assess the succession of bacterial communities associated with the decomposition of mouse cadavers and determine the most important biomarker taxa for estimating PMIs. High-throughput sequencing was used to investigate the bacterial communities of gravesoil samples with different PMIs, and a random forest model was used to identify biomarker taxa.

Initial PROMIS Scores Correlate With Operative and Nonoperative Management of Lateral Epicondylitis.

Background: Lateral epicondylitis (LE) is a common source of elbow pain. Treatment options include physical therapy (PT), corticosteroid injection, or surgery, but the efficacy of each remains unclear. In this study, we compare Patient-Reported Outcomes Measurement Information System (PROMIS) scores between patients treated both operatively and nonoperatively for LE.

A Novel Module Promotes Horizontal Gene Transfer in ORS571.

ORS571 contains an 87.6 kb integrative and conjugative element (ICE) that conjugatively transfers symbiosis genes to other rhizobia. Many hypothetical redundant gene fragments (rgfs) are abundant in ICE, but their potential function in horizontal gene transfer (HGT) is unknown.

A low noise transimpedance amplifier for optical receiver.

In this paper, a regulated cascode (RGC) structure and a shunt-feedback transimpedance amplifier are cascaded. By analyzing the average input-referred noise current, this paper used the method of adjusting the metal-oxide-semiconductor size and increasing the transimpedance gain to optimize the circuit noise characteristics without introducing redundant structures and noise sources. The measured results demonstrated that when the photodetector capacitance is 300 pF and the supply voltage is 1.

Development of a Murine Model of Pyogenic Flexor Tenosynovitis.

Background: Pyogenic flexor tenosynovitis is a debilitating infection of the hand flexor tendon sheath with high morbidity despite standard treatments of empiric antibiotics with irrigation and debridement. In vivo studies in the available literature have used avian models, but these models are difficult to scale and maintain. The purpose of this study was to demonstrate the plausibility of a murine model of pyogenic flexor tenosynovitis utilizing bioluminescence imaging and tissue analysis at harvest.

Learning Latent Spiculated Features for Lung Nodule Characterization.

Computer-aided Diagnosis (CAD) systems have long aimed to be used in clinical practice to help doctors make decisions by providing a second opinion. However, most machine learning based CAD systems make predictions without explicitly showing how their predictions were generated. Since the cognitive process of the diagnostic imaging interpretation involves various visual characteristics of the region of interest, the explainability of the results should leverage those characteristics.

VCAM1 Promotes Tumor Cell Invasion and Metastasis by Inducing EMT and Transendothelial Migration in Colorectal Cancer.

Vascular cell adhesion molecular 1 (VCAM1), an important member of the immunoglobulin superfamily, is related to the development of malignant tumors, such as breast cancer, melanoma, and renal clear cell carcinoma. However, the molecular role and mechanism of VCAM1 in the regulation of the progression of colorectal cancer (CRC) has rarely been studied. The results of IHC and RT-PCR analyses proved that VCAM1 was upregulated in human CRC tissues compared with matched adjacent normal intestinal epithelial tissues.

Surgical management of aggressive hemangiomas of the spine.

Our objective is to describe the surgical management and outcomes following surgical intervention for aggressive spine hemangiomas. Patients from 2005 to 2018 with an aggressive hemangioma of the cervical, thoracic, lumbar spine and sacrum treated surgically at a tertiary referral academic medical center were included in this study. The hospital pathology department database was used to identify patients with a diagnosis of aggressive hemangioma.

An improved multi-swarm particle swarm optimizer for optimizing the electric field distribution of multichannel transcranial magnetic stimulation.

Multichannel transcranial magnetic stimulation (mTMS) is a therapeutic method to improve psychiatric diseases, which has a flexible working pattern used to different applications. In order to make the electric field distribution in the brain meet the treatment expectations, we have developed a novel multi-swam particle swarm optimizer (NMSPSO) to optimize the current configuration of double layer coil array. To balance the exploration and exploitation abilities, three novel improved strategies are used in NMSPSO based on multi-swarm particle swarm optimizer.

What Is the Association Between Hospital Volume and Complications After Revision Total Joint Arthroplasty: A Large-database Study.

Background: Studies of primary total joint arthroplasty (TJA) show a correlation between hospital volume and outcomes; however, the relationship of volume to outcomes in revision TJA is not well studied.

Questions/purposes: We therefore asked: (1) Are 90-day readmissions more likely at low-volume hospitals relative to high-volume hospitals after revision THA and TKA? (2) Are in-hospital and 90-day complications more likely at low-volume hospitals relative to high-volume hospitals after revision THA and TKA? (3) Are 30-day mortality rates higher at low-volume hospitals relative to high-volume hospitals after revision THA and TKA?

Methods: Using 29,948 inpatient stays undergoing revision TJA from 2008 to 2014 in the Statewide Planning and Research Cooperative System (SPARCS) database for New York State, we examined the relationship of hospital revision volume by quartile and outcomes. The top 5 percentile of hospitals was included as a separate cohort.
