Magnetic resonance imaging-based radiomics model for preoperative assessment of risk stratification in endometrial cancer.

Background: Preoperative risk stratification is significant for the management of endometrial cancer (EC) patients. Radiomics based on magnetic resonance imaging (MRI) in combination with clinical features may be useful to predict the risk grade of EC.

Aim: To construct machine learning models to predict preoperative risk stratification of patients with EC based on radiomics features extracted from MRI.

The impacts of percutaneous coronary intervention to treat chronic total occlusion of right coronary artery on the 5-year prognosis: A single-centered retrospective study.

Background: Chronic total occlusions (CTO) occur in about 20% of patients referred for coronary angiography, and right coronary artery (RCA) CTO has been reported in 38-50% of the entire CTO population. Limited data on angiographic and procedural characteristics of RCA-CTO and the risk of adverse cardiac events asks for a detailed study.

Methods: From 2010 to 2013, patients with attempted revascularization of at least one CTO lesion were included and followed up to 5 years after PCI.

Targeted Delivery of Mesenchymal Stem Cell-Derived Bioinspired Exosome-Mimetic Nanovesicles with Platelet Membrane Fusion for Atherosclerotic Treatment.

Purpose: Accumulating evidence indicates that mesenchymal stem cells (MSCs)-derived exosomes hold significant potential for the treatment of atherosclerosis. However, large-scale production and organ-specific targeting of exosomes are still challenges for further clinical applications. This study aims to explore the targeted efficiency and therapeutic potential of biomimetic platelet membrane-coated exosome-mimetic nanovesicles (P-ENVs) in atherosclerosis.

Platelet-inspired targeting delivery for coronary heart disease.

Platelets play a pivotal role in many physiological and pathological processes, with their special targeting/adhering properties towards infarcted myocardium, injured or dysfunctional endothelium, and growing thrombus. Leveraging the site-targeting/adhering property, a variety of platelet-inspired targeting delivery（PITD）designs have been developed, the majority of which are reached by hitchhiking live platelets, cloaking nanoparticles with platelet membranes and mimicking platelet functions. With PITD, drugs or regenerative cells can directly reach targeted sites with minimized systematical distribution thus being of great clinical benefits.

OBIA: An Open Biomedical Imaging Archive.

With the development of artificial intelligence (AI) technologies, biomedical imaging data play an important role in scientific research and clinical application, but the available resources are limited. Here we present Open Biomedical Imaging Archive (OBIA), a repository for archiving biomedical imaging and related clinical data. OBIA adopts five data objects (Collection, Individual, Study, Series, and Image) for data organization, and accepts the submission of biomedical images of multiple modalities, organs, and diseases.

Assessing the clinical utility of multi-omics data for predicting serous ovarian cancer prognosis.

Ovarian cancer (OC) is characterised by heterogeneity that complicates the prediction of patient survival and treatment outcomes. Here, we conducted analyses to predict the prognosis of patients from the Genomic Data Commons database and validated the predictions by fivefold cross-validation and by using an independent dataset in the International Cancer Genome Consortium database. We analysed the somatic DNA mutation, mRNA expression, DNA methylation, and microRNA expression data of 1203 samples from 599 serous ovarian cancer (SOC) patients.

Impact of Marital Status on Management and Outcomes of Patients With Acute Myocardial Infarction: Insights From the China Acute Myocardial Infarction Registry.

Background Acute myocardial infarction (AMI) is one of the leading causes of mortality worldwide, whereas social support is a known predictor of the prognosis after AMI. As a common factor influencing social support, the impact of marital status on care quality, in-hospital mortality, and long-term prognosis of patients with AMI remains largely unknown. Methods and Results The present study analyzed data from the CAMI (China Acute Myocardial Infarction) registry involving 19 912 patients with AMI admitted at 108 hospitals in China between January 2013 and September 2014 and aimed to evaluate marital status-based differences in acute management, medical therapies, and short-term and long-term outcomes.

Direct mechanisms of SARS-CoV-2-induced cardiomyocyte damage: an update.

Myocardial injury induced by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is reportedly related to disease severity and mortality, attracting attention to exploring relevant pathogenic mechanisms. Limited by insufficient evidence, myocardial injury caused by direct viral invasion of cardiomyocytes (CMs) is not fully understood. Based on recent studies, endosomal dependence can compensate for S protein priming to mediate SARS-CoV-2 infection of CMs, damage the contractile function of CMs, trigger electrical dysfunction, and tip the balance of the renin-angiotensin-aldosterone system to exert a myocardial injury effect.

Pre-existing Health Conditions and Epicardial Adipose Tissue Volume: Potential Risk Factors for Myocardial Injury in COVID-19 Patients.

Myocardial injury is a life-threatening complication of coronavirus disease 2019 (COVID-19). Pre-existing health conditions and early morphological alterations may precipitate cardiac injury and dysfunction after contracting the virus. The current study aimed at assessing potential risk factors for COVID-19 cardiac complications in patients with pre-existing conditions and imaging predictors.

The influence of pre-existing hypertension on coronavirus disease 2019 patients.

Hypertension represents one of the most common pre-existing conditions and comorbidities in Coronavirus disease 2019 (COVID-19) patients. To explore whether hypertension serves as a risk factor for disease severity, a multi-centre, retrospective study was conducted in COVID-19 patients. A total of 498 consecutively hospitalised patients with lab-confirmed COVID-19 in China were enrolled in this cohort.

Pathogenesis and management of myocardial injury in coronavirus disease 2019.

The outbreak of coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, has become a major health crisis and a worldwide pandemic. COVID-19 is characterized by high infectivity, long incubation period, diverse clinical presentations, and strong transmission intensity. COVID-19 can cause myocardial injury as well as other cardiovascular complications, particularly in senior patients with pre-existing medical conditions.

Investigational pharmacotherapy and immunotherapy of pulmonary arterial hypertension: An update.

Pulmonary arterial hypertension (PAH) is a progressive disease with limited effective therapies that can be lethal in the terminal stage. Since the universal use of traditional PAH-specific drugs affecting the nitric oxide pathway, endothelin pathway and prostacyclin pathway, major advances to treat this devastating condition have been made. For example, it has been recently demonstrated that PAH is associated with various dysfunctional genes and molecular signaling pathways, abnormal metabolism and endocrine systems, inflammation and immune dysfunction.

Efficacy and safety of laparoscopy versus local injection with absolute ethanol in the management of tubal ectopic pregnancy.

Objective: To compare the efficacy and safety between laparoscopy and local injection with absolute ethanol (AE) for treating tubal ectopic pregnancy (EP).

Study Design: Retrospective cohort study of ectopic pregnancies in the fallopian tube from two tertiary hospitals between January 2015 and December 2017. Clinical information such as presenting symptoms, reproductive history, possible risk factors, initial diagnosis, serum beta-human chor-ionic gonadotropin (β-HCG) level, transvaginal ultrasonography findings, methods of treatment and outcomes were reviewed and analyzed.

G-CSF-mobilized peripheral blood mononuclear cells combined with platelet-rich plasma accelerate restoration of ovarian function in cyclophosphamide-induced POI rats†.

Peripheral blood mononuclear cells (PBMCs) are rich in hematopoietic cells and mesenchymal stem cells. Platelet-rich plasma (PRP) is rich in various growth factors. PBMCs and PRP have been suggested, individually, to restore ovarian function by improving the local microenvironment.
