Content Validation of the QOL-B-RD and PROMIS-F SF-7a to Measure Respiratory and Fatigue Symptoms of MAC Lung Disease.

Introduction: The Quality of Life-Bronchiectasis (QOL-B) questionnaire and Patient Reported Outcome Measurement Information System Short Form v1.0-Fatigue 7a (PROMIS-F SF-7a) have the potential to measure respiratory and fatigue symptoms, respectively, in patients with Mycobacterium avium complex (MAC) lung disease but have not yet been evaluated for content validity in this population.

Methods: Semi-structured qualitative interviews were conducted in United States patients with a current MAC lung disease diagnosis.

Cholic-Acid Derived, Guanidine-Functionalized Polymers as Broad-Spectrum Antimicrobial Agents.

In this study, we report the design of a new guanylated, cholic-acid-based monomer (GM) to combat antimicrobial resistance. The microbial activity stems from the interfacial amphiphilicity of cholic acid, while guanidine shows a strong association with phosphate, which promotes binding to membrane phospholipids. The monomer showed strong antimicrobial activity; however, surprisingly, homopolymers synthesized by photoiniferter reversible addition-fragmentation chain-transfer (RAFT) polymerization of GM completely lost their activity likely due to the conformation of the polymer.

Not too much, not too little-just the right amount: the story of YAP in the podocyte.

Chen et al. identify dysregulation of the transcriptional activator Yes-associated protein in the podocytes of diabetic mouse and human kidneys. Podocyte Yes-associated protein deficiency led to downregulation of the key transcription factor Wilms' tumor 1, and worsened podocyte injury in a mouse model of diabetic kidney injury.

Micropulse Transscleral Cyclophotocoagulation in Non-Incisional Eyes with Ocular Hypertension and Primary Open-Angle Glaucoma.

Purpose: To investigate the safety and effectiveness of micropulse transscleral cyclophotocoagulation (MPTSCPC) in non-incisional eyes with ocular hypertension (OHT) and early, moderate, and severe primary open-angle glaucoma (POAG).

Methods: Retrospective cohort study of eyes that underwent MPTSCPC from 2016 to 2019 at an outpatient clinic in Canada. Eyes were excluded if any incisional procedures, except cataract surgery, were performed prior to MPTSCPC treatment.
