Composite endpoints amalgamate multiple clinical outcomes into a single measure, offering efficiency gains in clinical trials through increased event rates and reduced sample sizes, thus accelerating clinical development and regulatory approval. However, employing composite endpoints introduces complexities into health technology assessments (HTAs), particularly in economic modeling, due to the varying clinical significance and cost implications of the components. In this paper, we explore best modeling practice for HTAs that are based on clinical trials that employ composite endpoints.

Epidemiology, pathophysiology, diagnosis and management of atrial functional mitral regurgitation: An expert opinion paper.

ESC Heart Fail

September 2025

Institute of Cardiology, ASST Spedali Civili, Department of Medical and Surgical Specialties, Radiological Sciences, and Public Health, University of Brescia, Brescia, Italy.

Atrial functional mitral regurgitation (AFMR) is an increasingly recognized subtype of mitral regurgitation, characterized by left atrial remodelling and mitral annular dilation in the absence of primary mitral valve disease or left ventricular dysfunction. Closely linked to chronic atrial fibrillation and heart failure with preserved ejection fraction, AFMR is associated with poor clinical outcomes and represents a growing therapeutic challenge. This expert opinion paper summarizes current evidence on the epidemiology, pathophysiology, diagnosis and management strategies, including medical therapy and emerging data supporting surgical and transcatheter interventions in selected patients.

Introduction: External continuous perturbations using a motion platform have been developed by employing either sum-of-sines (SoS) or a pseudorandom ternary sequence (PRTS) of numbers to quantify body sway evoked in the medial-lateral (ML) or anterior-posterior (AP) directions, which ultimately helps understand the human postural control system. These stimuli have been provided via pitch tilts of the motion platform for evaluations of AP balance responses or roll tilts for ML balance responses. However, little is known about whether a healthy postural control system responds to 2-dimensional (2D) perturbations similarly when the perturbation stimuli are provided in semicircular canal coordinates (i.

Although dynamical systems models are a powerful tool for analysing microbial ecosystems, challenges in learning these models from complex microbiome datasets and interpreting their outputs limit use. We introduce the Microbial Dynamical Systems Inference Engine 2 (MDSINE2), a Bayesian method that learns compact and interpretable ecosystems-scale dynamical systems models from microbiome timeseries data. Microbial dynamics are modelled as stochastic processes driven by interaction modules, or groups of microbes with similar interaction structure and responses to perturbations, and additionally, noise characteristics of data are modelled.

Mechanisms and treatment of cancer therapy-induced peripheral and central neurotoxicity.

Nat Rev Cancer

September 2025

Department of Neurology, Division of Neuro-Oncology, Massachusetts General Hospital Cancer Center, Harvard Medical School, Boston, MA, USA.

Neurotoxicity is a common and potentially severe adverse effect from conventional and novel cancer therapy. The mechanisms that underlie clinical symptoms of central and peripheral nervous system injury remain incompletely understood. For conventional cytotoxic chemotherapy or radiotherapy, direct toxicities to brain structures and neurovascular damage may result in myelin degradation and impaired neurogenesis, which eventually translates into delayed neurodegeneration accompanied by cognitive symptoms.
