Doppler-controlled microsurgical subinguinal varicocelectomy: a single centre experience

Вестник урологии
Introduction. Injury to the testicular artery during microsurgical subinguinal varicocelectomy (MSV) results in testicular atrophy in 20 – 40% of cases. The use of techniques that improve visualization of the testicular artery could increase the efficacy

Recanting Twins: Addressing Intermediate Confounding in Mediation Analysis

Statistics in Medicine, Volume 45, Issue 3-5, February 2026.
ABSTRACT The presence of intermediate confounders, also called recanting witnesses, is a fundamental challenge to the investigation of causal mechanisms in mediation analysis, preventing the identification of natural path‐specific effects. Common alternatives (such as randomizational interventional effects) are problematic because they can take non ...

Novel Hybrid Sparse and Low-Rank Representation With Auto-Weight Minimax Lγ Concave Penalty for Image Denoising

IEEE Access
Image denoising techniques often rely on convex relaxations, which can introduce bias into estimations. To address this, non-convex regularizers like weighted nuclear norm minimization and weighted Schatten p-norm minimization have been proposed. However,

Proton stereotactic body radiotherapy for early‐stage non‐small cell lung cancer: Influence of case‐specific characteristics on dosimetric robustness

Journal of Applied Clinical Medical Physics, Volume 27, Issue 1, January 2026.
Abstract Background and purpose Proton stereotactic body radiotherapy (SBRT) offers superior dose conformity. However, its clinical application remains limited due to uncertainties from setup errors and respiratory motion. This study quantified the dosimetric robustness of proton SBRT for early‐stage non‐small cell lung cancer under combined setup and ...

Feasibility of Simon Two‐Stage Futility Trials in People with Early, Symptomatically Treated Parkinson's Disease

Movement Disorders, Volume 41, Issue 1, Page 190-199, January 2026.
Abstract Background Disease‐modifying treatments are a critical unmet need in Parkinson's disease (PD). Phase 2 futility trials using the Simon two‐stage design offer an efficient strategy to evaluate candidate treatments in an early PD population. Objective The aim was to assess the feasibility of Simon two‐stage futility trials in early, levodopa ...
