AI Article Synopsis
- The study aimed to create and validate the Raynaud Specific Quality of Life Questionnaire (RQLQ) to assess the health-related quality of life in patients with Raynaud's disease (RD).
- The RQLQ was developed through interviews with RD patients, leading to a refined 29-item questionnaire that showed strong correlations with overall well-being and health outcomes.
- The RQLQ is the first specialized tool of its kind for RD patients, proving to be valid and reliable for both clinical research and practice.
Article Abstract
Introduction/objectives: The aim of this study was to develop and validate the Raynaud Specific Quality of Life Questionnaire (RQLQ) for assessing health-related quality (HRQOL) of life in patients with Raynaud's disease (RD).
Method: The questionnaire was developed and validated in three stages. Initially, semi-structured interviews with 28 RD patients identified domains of everyday life affected by RD, leading to the creation of the initial RQLQ. In the first quantitative stage, 101 patients completed the RQLQ, and exploratory factor analysis assessed dimensionality and factor structure. After removing poorly performing items, the final RQLQ was tested with 102 patients. This stage also evaluated convergent, divergent, and discriminant validity, as well as internal reliability.
Results: From the interviews, 135 items were generated, with factor analysis refining the measure to 29 items across five subscales, showing good internal consistency. The RQLQ demonstrated significant correlations with self-rated quality of life and physical and mental health outcomes, confirming convergent and divergent validity. It also showed discriminant validity for different levels of disease activity.
Conclusions: The RQLQ is the first specific HRQOL measure for RD patients, proving to be a psychometrically sound, reliable, and valid tool for clinical research and practice. Key Points • The Raynaud Specific Quality of Life Questionnaire (RQLQ) is an important scale that evaluates the quality of life of patients with Raynaud's disease. • The questionnaire showed good validity and reliability a capturing disease-specific quality of life. • This tool may aid in clinical research and practice.

Objective: This study focuses on epidermal growth factor receptor-mutated lung adenocarcinoma, known for frequent brain metastasis. It aimed to compare the clinical outcomes and cost-effectiveness of combining Gamma Knife radiosurgery (GKRS) with tyrosine kinase inhibitors (TKIs) (GKRS+TKI group) versus TKIs alone (TKI group) for the treatment of patients with newly diagnosed brain metastasis in this condition.
Methods: Study characteristics of the two groups were matched using inverse probability of treatment weighting (IPTW).
The Paradigm Shift From Patient to Health Consumer: 20 Years of Value Assessment in Health.

Health care is undergoing a "revolution," where patients are becoming consumers and armed with apps, consumer review scores, and, in some countries, high out-of-pocket costs. Although economic analyses and health technology assessment (HTA) have come a long way in their evaluation of the clinical, economic, ethical, legal, and societal perspectives that may be impacted by new technologies and procedures, these approaches do not reflect underlying patient preferences that may be important in the assessment of "value" in the current value-based health care transition. The major challenges that come with the transformation to a value-based health care system lead to questions such as "How are economic analyses, often the basis for policy and reimbursement decisions, going to switch from a societal to an individual perspective?" and "How do we then assess (economic) value, considering individual preference heterogeneity, as well as varying heuristics and decision rules?" These challenges, related to including the individual perspective in cost-effectiveness analysis (CEA), have been widely debated.

Objective: The goal of this study was to compare the impact of using a lower thoracic (LT) versus upper lumbar (UL) level as the upper instrumented vertebra (UIV) on clinical and radiographic outcomes following minimally invasive surgery for adult spinal deformity.
Methods: A multicenter retrospective study design was used. Inclusion criteria were age ≥ 18 years, and one of the following: coronal Cobb angle > 20°, sagittal vertical axis > 50 mm, pelvic tilt > 20°, pelvic incidence-lumbar lordosis mismatch > 10°.
