People living with hemophilia A face challenges impacting their daily lives despite treatment innovations. Previous studies have explored perceptions and treatment experiences; however, there is a lack of an evidence-based, comprehensive model to identify concepts (clinical, physical, and psychological functioning) relevant for people with hemophilia A (PwHA). The aim of this qualitative study was to address the question: What is the humanistic and symptomatic experience of adolescents, adults, and children living with hemophilia A and what is the impact of hemophilia A on their quality of life? Participants, identified through patient associations in the UK, were male PwHA and caregivers of male PwHA receiving prophylactic treatment.

- This study explores the patient experience of non-metastatic cutaneous squamous cell carcinoma (CSCC), focusing on identifying common symptoms and impacts on quality of life.
- The researchers developed a conceptual model by reviewing literature, analyzing patient blogs, and conducting interviews with both patients and dermatologists.
- They found that existing patient-reported outcome (PRO) instruments, particularly the FACE-Q Skin Cancer, need enhancements to better address the physical, psychological, and behavioral aspects of CSCC treatment experiences.
Genotype-phenotype correlations add value to the management of families with hereditary hearing loss (HL), where age-related typical audiograms (ARTAs) are generated from cross-sectional regression equations and used to predict the audiogram phenotype across the lifespan. A seven-generation kindred with autosomal dominant sensorineural HL (ADSNHL) was recruited and a novel pathogenic variant in POU4F3 (c.37del) was identified by combining linkage analysis with whole exome sequencing (WES).

Therefore, this study aimed to develop a de novo instrument to comprehensively assess the patient experience of PDR.
Methods: This qualitative, mixed-methods study comprised item generation for the Diabetic Retinopathy-Patient Experience Questionnaire (DR-PEQ), content validation in patients with PDR, and preliminary Rasch measurement theory (RMT) analyses.
