Development and validation of a prediction model for heart failure in patients with heart valvular regurgitation.

Aims: Patients with heart valvular regurgitation is increasing; early screening of potential patients developing heart failure (HF) is crucial.

Methods: From 1 November 2019 to 31 October 2023, a total of 509 patients with heart valvular regurgitation hospitalized in the Department of Cardiovascular Disease of the First Affiliated Hospital of Guangzhou University of Traditional Medicine were enrolled. Three hundred fifty-six cases were selected as the training set for modelling, and 153 cases were selected as the validation set for the internal validation of the model.

Incidence and characteristic of deep venous thrombosis in hospitalized chronic heart failure patients.

Background: This study was conducted to investigate the incidence of deep venous thrombosis (DVT), outcomes and its characteristics in patients with chronic heart failure (CHF) in a retrospective setting.

Outcomes: Patients died of cardiac shock or acute exacerbation of heart failure (HF), admitted to intensive care unit (ICU) due to acute exacerbation of HF, patients decided to withdraw treatment and return home due to acute exacerbation of HF.

Methods: From January 2015 to June 2022, we admitted 359 patients diagnosed with CHF, and lower limb ultrasonography was performed for the examination of DVT after admission.

Red meat consumption and risk for dyslipidaemia and inflammation: A systematic review and meta-analysis.

Aim: The study (PROSPERO: CRD42021240905) aims to reveal the relationships among red meat, serum lipids and inflammatory biomarkers.

Methods And Results: PubMed, EMBASE and the Cochrane databases were explored through December 2021 to identify 574 studies about red meat and serum lipids markers including total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), C-reactive protein (CRP) or hypersensitive-CRP (hs-CRP). Finally, 20 randomized controlled trials (RCTs) involving 1001 people were included, red meat and serum lipid markers and their relevant information was extracted.

[The effect of marrow mesenchymal stem cell transplantation on pulmonary fibrosis in rats].

Objective: To study the possible mechanisms of marrow mesenchymal stem cells (MSC) in therapy of bleomycin (BLM)-induced pulmonary fibrosis in rats.

Methods: Fifty-four female Wistar rats were randomly divided into a control group, a BLM group and a MSC group. The control group received intratracheal normal saline, the BLM group received intratracheal instillation of bleomycin, and the MSC group was injected with male rat MSC solution of 0.
