Indicators to evaluate quality of care in head and neck cancer in Spain.

PURPOSE: This study aimed to develop a set of criteria and indicators to evaluate the quality of care of patients with head and neck cancer (HNC). METHODS: A systematic literature review was conducted to identify valuable criteria/indicators for the assessment of the quality of care in HNC. With the aid of a technical group, a scientific committee of oncologists specialised in HNC used selected criteria to propose indicators that were evaluated with a two-round Delphi method. Indicators on which consensus was achieved were then prioritised by the scientific committee to develop a final set of indicators. RESULTS: We proposed a list of 50 indicators used in the literature or developed by us to be evaluated with a Delphi method. There was consensus on the appropriateness of 47 indicators in the first round; the remaining 3 achieved consensus in the second round. The 50 indicators were scored to prioritise them, leading to a final selection of 29 indicators related to structure (3), process (22), or outcome (4) and covering diagnosis, treatment, follow-up, and health outcomes in patients with HNC. Easy-to-use index cards were developed for each indicator, with their criterion, definition, formula for use in real-world clinical practice, rationale, and acceptable level of attainment. CONCLUSIONS: We have developed a set of 29 evidence-based and expert-supported indicators for evaluating the quality of care in HNC, covering diagnosis, treatment, follow-up, and health outcomes.

Intermediate molecular phenotypes to identify genetic markers of anthracycline-induced cardiotoxicity risk.

Cardiotoxicity due to anthracyclines (CDA) affects cancer patients, but we cannot predict who may suffer from this complication. CDA is a complex disease whose polygenic component is mainly unidentified. We propose that levels of intermediate molecular phenotypes in the myocardium associated with histopathological damage could explain CDA susceptibility; so that variants of genes encoding these intermediate molecular phenotypes could identify patients susceptible to this complication. A genetically heterogeneous cohort of mice generated by backcrossing (N = 165) was treated with doxorubicin and docetaxel. Cardiac histopathological damage was measured by fibrosis and cardiomyocyte size by an Ariol slide scanner. We determine intramyocardial levels of intermediate molecular phenotypes of CDA associated with histopathological damage and quantitative trait loci (ipQTLs) linked to them. These ipQTLs seem to contribute to the missing heritability of CDA because they improve the heritability explained by QTL directly linked to CDA (cda-QTLs) through genetic models. Genes encoding these molecular subphenotypes were evaluated as genetic markers of CDA in three cancer patient cohorts (N = 517) whose cardiac damage was quantified by echocardiography or Cardiac Magnetic Resonance. Many SNPs associated with CDA were found using genetic models. LASSO multivariate regression identified two risk score models, one for pediatric cancer patients and the other for women with breast cancer. Molecular intermediate phenotypes associated with heart damage can identify genetic markers of CDA risk, thereby allowing a more personalized patient management. A similar strategy could be applied to identify genetic markers of other complex trait diseases.

Epidemiological Study of Prostate Cancer in the Province of Salamanca (2006-2015).

OBJECTIVES: Knowing the incidence of prostate cancer in Salamanca and its evolution, as well as the age at diagnosis and its evolution. In addition, analyzing the mortality from prostate cancer in the province of Salamanca. METHODS: Descriptive and analytical, longitudinal and retrospective observational study. From the collection of data from the Pathological Anatomy service and the Clinical Documentation service of the Hospital Complex of Salamanca a database was developed for the calculation of incidence rates. The information collected on mortality was obtained through the National Institute of Statistics. For regression analysis, segmented "jointpoint" models were developed. RESULTS: 2676 males diagnosed with prostate cancer were recorded in the province of Salamanca (period 2006-2015). The risk of prostate cancer up to age 74 in 2006 was 6.23%, almost double in 2010. The evolution of mortality rates adjusted to the European population in the province of Salamanca during the period 2006-2015 showed a slight decrease. CONCLUSIONS: In general, Prostate cancer incidence rates increased progressively over the years studied, similar to Spain's overall rates. These rates increased as age progressed. In general, our incidence rates were lower than those reported by the provinces of northern Spain (except Vizcaya) and higher than those recorded by the provinces of southern Spain. In Europe, our rate was surpassed by countries in northern and western Europe and lower than countries in southern and eastern Europe, and part of central Europe. Countries like U.S.A had rates higher than ours, while Canada accounted for a similar rate. On the other hand, mortality rates remained stable during the middle of the study period, suffering from then on a non-statistically significant anual decrease.

Adaptation and validation of the Spanish version of the everyday cognition battery for assessing everyday cognition in older adults.

INTRODUCTION: Ageing entails a series of neuroanatomical and neurophysiological changes in some cognitive processes that directly affect the daily life and autonomy of a person. We believe it is necessary to have tools that assess the cognitive functions that are essential for carrying out daily activities in an independent manner. The aim of this study was to translate the Everyday Cognition Battery (ECB) into Spanish, adapt it to the sociocultural context of Spain, and validate it by testing the psychometric properties, i.e., the reliability and validity of the translated version. METHODS: The translation and adaptation of the ECB into Spanish was carried out following the method recommended by Beaton et al., the process concluding with a pilot test to ensure that subjects were able to understand the scale correctly. Between March and October 2019, the study population voluntarily completed the translated version of each of the four subscales that make up the battery of tests. The translated version was validated by analysing its psychometric properties, using reliability or internal consistency tests assessed with Cronbach's alpha coefficient and validity tests analysed using correlation tables and Spearman's correlation coefficient. The scale considered to represent the gold standard in the assessment of cognition was the Rapid Assessment of Cognitive Functions (RACF), and to assess Instrumental Activities of Daily Living (IADL) this was the Lawton and Brody Index. RESULTS: The total study population included 226 subjects, of which 52 participants were excluded, resulting in a study sample size of 174 older adults. The recognition, inductive reasoning and computation span tests showed good reliability (Cronbach's alpha coefficient of > 0.827, > 0.836, and > 0.823, respectively), while the knowledge test showed questionable reliability with a Cronbach's alpha coefficient of > 0.615. The validity analysis demonstrated that all the combinations of correlations of the different scales were significantly and positively related to one another. CONCLUSIONS: The Spanish version of the ECB tool is socially and culturally equivalent to the original version, and both its validity and reliability for assessing everyday cognition in older adults have been demonstrated.
