The adapted Caprini score as a proxy forpostoperative venous thromboembolismprophylaxis: a tertiary hospital experience.
S Afr J Surg
December 2024
Department of Biostatistics, Faculty of Health Sciences, University of the Free State, South Africa.
Background: Postoperative patients' risk for developing venous thromboembolism (VTE) can be predicted using the adapted Caprini risk assessment model which informs administration of postoperative VTE prophylaxis. The study aimed to assess the appropriateness of postoperative VTE prophylaxis of patients according to the adapted Caprini scores and investigate whether a patient's HIV status influenced postoperative VTE prophylaxis administration.
Methods: This cohort study included patients who had elective or urgent surgery at a tertiary hospital, Bloemfontein.
Quantitative Prediction of Protein-Polyelectrolyte Binding Thermodynamics: Adsorption of Heparin-Analog Polysulfates to the SARS-CoV-2 Spike Protein RBD.

Interactions of polyelectrolytes (PEs) with proteins play a crucial role in numerous biological processes, such as the internalization of virus particles into host cells. Although docking, machine learning methods, and molecular dynamics (MD) simulations are utilized to estimate binding poses and binding free energies of small-molecule drugs to proteins, quantitative prediction of the binding thermodynamics of PE-based drugs presents a significant obstacle in computer-aided drug design. This is due to the sluggish dynamics of PEs caused by their size and strong charge-charge correlations.

The hemostatic system prevents and stops bleeding, maintaining circulatory integrity after injury. It directly interacts with the complement system, which is key to innate immunity. In coronavirus disease 2019 (COVID-19), dysregulation of the hemostatic and complement systems has been associated with several complications.

We investigated the safety and efficacy of rivaroxaban as routine thromboprophylaxis after endovenous thermal ablation (EVTA). Adhering to the PRISMA 2020 guidelines, we conducted a systematic review for studies published up to April 2024. Primary endpoints included endovenous heat-induced thrombosis (EHIT) class ≥ II, deep vein thrombosis (DVT), major and minor bleeding and the composite endpoint of major thromboembolic complications including any incidents of EHIT ≥ III, DVT or pulmonary embolism (PE).

The CRISPR-based detection methods have been widely applied, yet they remain limited by the non-universal nature of one-pot diagnostic approaches. Here, we report a universal one-pot fluorescent method for the detection of epidemic pathogens, delivering results within 15-20 min. This method uses heparin sodium to precisely tunes the cis-cleavage capability of Cas12 via interference with the Cas12a-crRNA binding process, thereby generating significant fluorescence due to the accumulation of isothermal amplification products.
