What is the robustness of randomized controlled trials supporting rhinosinusitis guidelines?

Purpose: To determine the robustness of randomized controlled trials (RCTs) supporting the current rhinosinusitis guideline; International Consensus Statement on Allergy and Rhinology: rhinosinusitis (ICAR-RS).

Materials & Methods: RCTs referenced by ICAR-RS with primary dichotomous outcomes were analyzed. The Fragility Index (FI) was calculated for trials with statistically significant findings.

Recent Progress in the Synthesis of Benzoxazin-4-Ones, Applications in N-Directed Ortho-Functionalizations, and Biological Significance.

The development of efficient synthetic procedures to access fused N, O-heterocyclic skeletons has been a pivotal research topic in organic synthesis for several years. Owing to the applications of N, O-fused heterocycles in organic synthesis, material sciences, and medicinal chemistry, significant efforts have been dedicated to design novel methods for their construction. To this end, 1,3-benzoxazin-4-ones are privileged candidates for N, O-heterocyclic molecules often found in natural products, agrochemicals, and materials science applications.

Repurposing an epithelial sodium channel inhibitor as a therapy for murine and human skin inflammation.

Inflammatory skin disease is characterized by a pathologic interplay between skin cells and immunocytes and can result in disfiguring cutaneous lesions and systemic inflammation. Immunosuppression is commonly used to target the inflammatory component; however, these drugs are often expensive and associated with side effects. To identify previously unidentified targets, we carried out a nonbiased informatics screen to identify drug compounds with an inverse transcriptional signature to keratinocyte inflammatory signals.

Determinants of long-term paramagnetic rim lesion evolution in people with multiple sclerosis.

Objective: Baseline paramagnetic rim lesion (PRL) load predicts disease progression in people with multiple sclerosis (pwMS). Understanding how PRLs relate to other known MS-related factors, and the practical utility of PRLs in clinical trials, is crucial for informing clinical decision-making and guiding development of novel disease-modifying treatments (DMTs).

Methods: This study included 152 pwMS enrolled in a larger prospective, longitudinal cohort study who had 3T MRI scans and clinical assessments at baseline and 5- or 10-year follow-ups.
