Article Abstract

Secondary mitral regurgitation (SMR) is common in patients with heart failure (HF). Although randomized clinical trials have been focused on the treatment of severe SMR, the prognostic role and potential for treatment of moderate SMR cannot be overlooked. The randomized RESHAPE-HF2 trial included patients with moderate and severe SMR with consistent findings in both groups, raising the hypothesis that transcatheter correction of moderate SMR could have beneficial effects, although this needs further investigation. The aim of this review is to describe the prevalence of moderate SMR in patients with HF, its prognostic impact, and discuss current evidence for pharmacologic and interventional management of patients with moderate SMR.

Secondary mitral regurgitation (SMR) remains a prevalent and challenging complication in patients with heart failure (HF), associated with poor prognosis despite optimal guideline-directed medical therapy (GDMT) and cardiac resynchronization therapy. Current American and European guidelines recommend GDMT as first-line therapy, with transcatheter edge-to-edge repair (TEER) reserved for severe symptomatic SMR patients who remain refractory. However, both guidelines preceded the reporting of pivotal randomized controlled trials (RESHAPE-HF2, MATTERHORN, and EFFORT) and emerging evidence in new clinical scenarios.

Effective communication among intensive care professionals is essential for patient safety and outcome optimization. Multiprofessional rounds supported by checklists have demonstrated the potential to improve the quality of care, particularly in high-income settings. However, evidence remains limited for low- and middle-income countries (LMICs).

Background: Providing personalized risk information to patients and their providers could improve colorectal cancer (CRC) screening.

Objective: To determine whether providing information on patient risk for advanced colorectal neoplasia (ACN; which includes CRC and advanced precancerous lesions) to patients and providers affects screening uptake, and to identify effect moderators.

Design: Randomized controlled trial (2 × 2 factorial design).

Introduction Acute pancreatitis (AP) is a potentially life-threatening inflammatory disorder of the pancreas with a wide spectrum of clinical manifestations. Early identification of disease severity is critical for guiding management and improving outcomes. Prognostic scoring systems such as the Bedside Index for Severity in Acute Pancreatitis (BISAP) and the CT severity index (CTSI) are commonly used to predict disease progression and complications.
