The impact of the board of directors and the audit committee on the transparency of financial information of companies listed in a frontier market.

This study aims to evaluate the impact of factors representing the Board of Directors (BOD) and Audit Committee (AC) on financial information transparency (FIT) in a frontier market. FIT is measured through three indicators that reflect financial non-transparency: earnings aggressiveness (EA), earnings smoothing (ES) and loss avoidance (LA). Research data was collected from 338 companies listed on the Vietnam Stock Exchange (HOSE and HNX) from 2012 to 2022.

Combination of Hotspot Mutations With Methylation and Fragmentomic Profiles to Enhance Multi-Cancer Early Detection.

Background: Multi-cancer early detection (MCED) through a single blood test significantly advances cancer diagnosis. However, most MCED tests rely on a single type of biomarkers, leading to limited sensitivity, particularly for early-stage cancers. We previously developed SPOT-MAS, a multimodal ctDNA-based assay analyzing methylation and fragmentomic profiles to detect five common cancers.

Endobronchial Ultrasound Guided Transbronchial Needle Aspiration of Solitary Lung Nodules and the Triple Diagnosis Technique: Does Triple Diagnosis Improve Diagnostic Accuracy?

Background: Endobronchial ultrasound guided Transbronchial Needle Aspiration (EBUS-TBNA) is the predominant method for investigation of centrally located solitary pulmonary nodules. The method is associated with good to excellent diagnostic sensitivity and specificity with the positive predictive value of the test reaching 100% and reported negative predictive values for FNA of pulmonary nodules ranging from 53% to 97%. The impact of correlating cytologic results with imaging and clinical findings for improvement of negative predictive value has been poorly studied.

Maximizing nutrient removal: unveiling the influence of biomass retention time in revolving algae biofilm reactor.

This study introduces a novel Revolving Algae Biofilm reactor for synthetic wastewater treatment, examining the influence of various biomass retention times (BRTs) on nutrient removal performance. The study reveals complex interactions between microalgae and bacteria, emphasizing their symbiotic functions in oxygen provision, nutrient absorption, and floc creation. This research contributes to the advancement of sustainable wastewater treatment methods, showing promise for large-scale nutrient removal in industrial settings.
