Soluble Transferrin Receptor as Iron Deficiency Biomarker: Impact on Exercise Capacity in Heart Failure Patients

The soluble transferrin receptor (sTfR) is a marker of tissue iron status, which could indicate an increased iron demand at the tissue level. The impact of sTfR levels on functional capacity and quality of life (QoL) in non-anemic heart failure (HF) patients with otherwise normal systemic iron status has not been evaluated. We conducted an observational, prospective, cohort study of 1236 patients with chronic HF. We selected patients with normal hemoglobin levels and normal systemic iron status. Tissue iron deficiency (ID) was defined as levels of sTfR > 75th percentile (1.63 mg per L). The primary endpoints were the distance walked in the 6 min walking test (6MWT) and the overall summary score (OSS) of the Minnesota Living with Heart Failure Questionnaire (MLHFQ). The final study cohort consisted of 215 patients. Overall QoL was significantly worse (51 +/- 27 vs. 39 +/- 20, p-value = 0.006, respectively), and the 6 MWT distance was significantly worse in patients with tissue ID when compared to patients without tissue ID (206 +/- 179 m vs. 314 +/- 155, p-value < 0.0001, respectively). Higher sTfR levels, indicating increased iron demand, were associated with a shorter distance in the 6 MWT (standardized beta = -0.249, p < 0.001) and a higher MLHFQ OSS (standardized fi = 0.183, p-value = 0.008). In this study, we show that in patients with normal systemic iron parameters, higher levels of sTfR are strongly associated with an impaired submaximal exercise capacity and with worse QoL

Spanish version of the short European Health Literacy Survey Questionnaire HLS-Q12 : Transcultural adaptation and psychometric properties

Health literacy has a direct impact on the health of populations. It is related to education, capacity for self-care, and management of health resources. The Health Literacy Survey Questionnaire HLS-Q12 is one of the reference instruments but has not yet been adapted to Spanish. The aims of the study were to cross-culturally adapt and evaluate the psychometric properties of the Spanish version of the HLS-Q12. Data was collected from June 2020 to March 2022. The sample consisted of 60 patients who initiated cancer treatment for the first time within a clinical trial. Double direct translation, back-translation, cognitive debriefing with a 10-patient sample, and an expert committee were used for cross-cultural adaptation. For validation of the HLS-Q12, a psychometric analysis was performed to assess feasibility, reliability, sensitivity to change and construct validity with other measures such as health-related quality of life, empowerment, and health needs. The HLS-Q12 is equivalent at the semantic, conceptual, and content level to the original version and its psychometric properties demonstrated good internal consistency with a Cronbach's alpha of 0.88 and a McDonald's omega of 0.91, a high degree of fit for the confirmatory factor analysis, and a statistically significant sensitivity to change (p = 0.025). Based on robust psychometric values, the Spanish version of HLS-Q12 was found to be a good cross-culturally adapted tool for collecting correct information on health literacy in cancer patients regardless of tumour type or stage. Although more studies are needed, this version of HLS-Q12 could be used in research for collecting data on the health literacy needs of Spanish-speaking patients

Abstract: Purpose: To describe the process of translation and cultural adaptation of the Patient empowerment in long-term condition to the Spanish language. Design: Translation, cross-cultural adaptation, and pilot testing (cognitive debriefing) Location: Primary and Hospital care. Participants: Ten patients admitted to a cardiology department of a University Hospital Main measurements: 1) Direct translation, 2) conciliation and synthesis of the versions by expert panel, 3) back- translation, 4) agreement on the back-translated version with the author of the original version, 5) analysis of comprehensibility through cognitive interviews. Results: There were no differences between the direct-translated versions. The expert panel introduced changes in 23 out of the 47 items of the questionnaire. The author of the original version agreed with the version of the back-translation. In the cognitive interviews, patients reported high difficulty in one item and low difficulty in 4. Conclusions: The Spanish version of the Patient Empowerment in long-term conditions questionnaire is semantically and conceptually equivalent to the original tool. The assessment of the psychometric properties of the Spanish version of the questionnaire will be carried out at a later stage.
