Mapping the EQ-5D-5L from the Spanish national health survey functional disability scale through Bayesian networks.

PURPOSE: Preference-based measures are valuable tools for evaluating therapeutic interventions and for cost-effectiveness studies. Mapping procedures are useful when it is not possible to collect these kind of measures. The objective of this study was to evaluate which mapping method is the most appropriate to estimate the EQ-5D-5L index from the Spanish National Health Survey functional disability scale. METHODS: The sample, formed by 5708 older adults (aged 65 years or older), was drawn from the Spanish National Health Survey ("Encuesta Nacional de Salud en España," ENSE in Spanish 2011-2012). The predictions of EQ-5D-5L index were performed with response mapping using Bayesian network (BN), ordered logit (Ologit), and multinomial logistic (ML). The following direct methods were used: ordinary least squares (OLS) and Tobit regression. The intraclass correlation coefficient (ICC), absolute error (MAE), mean squared error (MSE), and root-mean squared error (RMSE) were calculated to compare all models. The predictions of response models were obtained through the expected value method. RESULTS: BN model showed the highest ICC (0.756, 95% confidence interval, CI 0.733-0.777) and lowest MAE (0.110, 95% CI 0.104-0.115). OLS was the model with worse accuracy results with lowest ICC (0.621, 95% CI 0.553-0.681) and highest MAE (0.159, 95%CI: 0.145-0.173). CONCLUSION: Indirect mapping methods (BN, Ologit, and ML) had a better accuracy than the direct methods. The response mapping approach provides a robust method to estimate EQ-5D-5L scores from the functional disability scale.

Factors associated with patient empowerment in Spanish adults with type 2 diabetes: A cross-sectional analysis.

OBJECTIVE: The aim of the present study is to identify factors associated with patient empowerment in people living with type 2 diabetes mellitus (T2DM) in the Canary Islands (Spain). METHODS: Secondary cross-sectional analysis was carried out of data obtained in the INDICA study: A 24-month cluster randomized-controlled trial evaluating the effectiveness of educational interventions supported by new technology decision tools for T2DM patients. Sociodemographic variables, clinical data (years since diagnosis, glycated haemoglobin level, creatine, triglycerides, waist hip index, body mass index and number of comorbidities), diabetes knowledge (DIATEK), affective outcomes (Beck Depression Inventory-II, the State subscale of the State-Trait Anxiety Inventory and The Diabetes Distress Scale) and diabetes-related quality of life (The Audit of Diabetes-Dependent Quality of life) were assessed as potential correlates of patient empowerment, assessed using the Diabetes Empowerment Scale-Short Form. Multilevel mixed linear regression models on patient empowerment were developed. RESULTS: The analysis included the baseline data of 2334 patients. Results showed that age (B = -0.14; p < .001), diabetes knowledge (B = 0.61; p < .001) and state-anxiety (B = -0.09; p < .001) are significantly associated with patient empowerment. Sex, education level, living alone, employment status, country of birth, time since diagnosis, number of comorbidities, glycated haemoglobin level, depression and distress were not independently associated with patient empowerment in the multivariate analyses. CONCLUSION: Younger age, lower state-anxiety and greater diabetes-specific knowledge are important correlates of patient empowerment. In line with the results of the INDICA study, interventions based on patient-centred care might be effective in improving patient empowerment in adults with T2DM. Understanding the factors associated with empowerment may help clinicians and policymakers to identify high-risk groups, prioritize resources and target evidence-based interventions to better support people with T2DM to be actively involved in their own care. PATIENT OR PUBLIC CONTRIBUTION: Patients with T2DM were actively involved in the design of the INDICA study. Two patient associations were included as part of the research team and actively participated in designing the interventions and selecting outcome measures.

Response Mapping Methods to Estimate the EQ-5D-5L From the Western Ontario McMaster Universities Osteoarthritis in Patients With Hip or Knee Osteoarthritis.

OBJECTIVES: The mapping technique can estimate generic preference-based measure scores through a specific measure that cannot be used in economic evaluations. This study compared 2 response mapping methods to estimate EQ-5D-5L scores using the Western Ontario McMaster Universities Osteoarthritis (WOMAC). METHODS: The sample consisted of 758 patients with the hip or knee osteoarthritis recruited in baseline. Bayesian networks (BN) and multinomial logistic regression (ML) were used as response mapping models. Predictions were obtained using the 6-month follow-up as a validation sample. The mean absolute error, mean squared error, deviation from the root mean squared error and intraclass correlation coefficient were calculated as precision measures. RESULTS: There was 5.5% of missing data, which was removed. The mean age was 69.6 years (standard deviation = 10.5), with 61.6% of women. The BN model presented lower mean absolute error, mean squared error, root mean squared error and higher intraclass correlation coefficient than the ML model. Only the WOMAC items pain and physical function items were related with the EQ-5D-5L dimensions. CONCLUSION: BN response mapping models are more robust methods, with better prediction results, than ML models. The BN model also provided a graphic representation of the dependency relationships between the EQ-5D-5L dimensions and the different WOMAC items that could be useful in the clinical investigation of patients with hip or knee osteoarthritis.

Postlaunch evidence-generation studies for medical devices in Spain: the RedETS approach to integrate real-world evidence into decision making.

The Monitoring Studies (MS) program, the approach developed by RedETS to generate postlaunch real-world evidence (RWE), is intended to complement and enhance the conventional health technology assessment process to support health policy decision making in Spain, besides informing other interested stakeholders, including clinicians and patients. The MS program is focused on specific uncertainties about the real effect, safety, costs, and routine use of new and insufficiently assessed relevant medical devices carefully selected to ensure the value of the additional research needed, by means of structured, controlled, participative, and transparent procedures. However, despite a clear political commitment and economic support from national and regional health authorities, several difficulties were identified along the development and implementation of the first wave of MS, delaying its execution and final reporting. Resolution of these difficulties at the regional and national levels and a greater collaborative impulse in the European Union, given the availability of an appropriate methodological framework already provided by EUnetHTA, might provide a faster and more efficient comparative RWE of improved quality and reliability at the national and international levels.

Mapping WOMAC Onto the EQ-5D-5L Utility Index in Patients With Hip or Knee Osteoarthritis.

OBJECTIVES: To map the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) onto the EQ-5D-5L in patients with hip or knee osteoarthritis (OA). METHODS: A prospective observational study was conducted on 758 patients with hip or knee OA who completed the EQ-5D-5L and WOMAC questionnaires, of whom 644 completed them both again 6 months later. Baseline data were used to derive mapping functions. Generalized additive models were used to identify to which powers the WOMAC subscales should be raised to achieve a linear relationship with the response. For the modeling, general linear models (GLM), Tobit models, and beta regression models were used. Age, sex, and affected joints were also considered. Preferred models were selected based on Akaike and Bayesian information criteria, adjusted R2, mean absolute error (MAE), and root mean squared error (RMSE). The functions were validated with the follow-up data using MAE, RMSE, and the intraclass correlation coefficient. RESULTS: The preferred models were a GLM with Pain2+Pain3+Function+Pain·Function as covariates and a beta model with Pain3+Function+Function2+Function3 as covariates. The adjusted R2 were similar (0.6190 and 0.6136, respectively). The predictive performance of these models in the validation sample was similar and both models showed an overprediction for health states worse than death. CONCLUSION: To our knowledge, these are the first functions mapping the WOMAC onto the EQ-5D-5L in patients with hip or knee OA. They showed an acceptable fit and precision and could be very useful for clinicians and researchers when cost-effectiveness studies are needed and generic preference-based health-related quality of life instruments to derive utilities are not available.

Suicide Coverage in the Digital Press Media: Adherence to World Health Organization Guidelines and Effectiveness of Different Interventions Aimed at Media Professionals.

This study evaluated the characteristics of suicide news articles in the digital press, their adherence to World Health Organization (WHO) recommendations, and the effectiveness of interventions. We assessed adherence, avoidability, frequency and typology of suicide news over a six-month period in the four main digital media outlets of the Canary Islands (Spain). A brief training and information package intervention to the Canary Islands media outlets was carried out. We compared the quality of media reporting at both the pre-intervention and post-intervention timepoints, and compared the quality of reporting at the post-intervention timepoint in Victoria (Australia), where media interventions have been well-resourced and running for several years. We evaluated 339 suicide news articles: 38 from the pre-intervention period, 64 from the post-intervention period, and 237 from Victoria. News articles showed a very low degree of adherence to WHO recommendations, especially to those recommendations thought to have a protective effect. Post-intervention news articles showed better adherence than pre-intervention ones, but lower than those of Victoria, where constant interventions have been developed for years. We conclude that adherence to WHO recommendations is low. Simple interventions aimed at media professionals can improve adherence. However, constant and complex interventions seem to be more effective.

Prospective study of variables associated with nonadherence to psychotherapy.

Background: The identification of factors associated with nonadherence to psychotherapy would allow a better prevention of this problem.Aim: To investigate factors associated with nonadherence in psychotherapy, its possible effect on outcomes, and reasons for therapy dropout.Method: Prospective analytic observational study of patients who initiated psychotherapy (N = 144). Sociodemographic, general clinical, treatment-related, subjective, psychological, psychopathologic, and outcome variables were evaluated at baseline and 1, 3, 6, and 12 months later. Objective nonadherence (dropout and irregularity), subjective nonadherence (poor patient engagement), and global nonadherence (combination of both) were analyzed.Results: Global nonadherence was 66%. Global nonadherence was associated with substance use or abuse (OR = 2.64) and younger age (OR = 0.97). Objective nonadherence was associated with active working status (OR = 4.11), younger age (OR = 1.04) and substance use or abuse (OR = 2.35). Subjective nonadherence was associated with worse insight in psychotherapy (OR = 0.95) and poor pharmacologic adherence (OR = 0.55). Contextual reasons (25.8%) were the most commonly reported cause of dropout. Time in psychotherapy was associated with outcome variables.Conclusions: Nonadherence to psychotherapy is frequent. To reduce nonadherence in psychotherapy, specific interventions for reducing substance use and abuse, measures aimed at facilitating access to Community Mental Health Units, and enhancing insight in psychotherapy should be implemented.

Subcutaneous implantable cardioverter-defibrillator in primary and secondary prevention of sudden cardiac death: A meta-analysis.

BACKGROUND: Subcutaneous implantable cardioverter-defibrillator (S-ICD) is gaining in popularity for primary and secondary prevention of sudden cardiac death. The objective was to evaluate the safety and clinical effectiveness of the S-ICD for prevention of sudden cardiac death compared to transvenous cardioverter-defibrillator (TV-ICD). METHODS: A systematic review with meta-analyses was performed. The electronic databases MEDLINE, EMBASE, SCI, and Cochrane Central Register of Controlled Trials were consulted in March 2018 with no restrictions on publication date. Predefined criteria were used to determine inclusion of studies and to assess their methodologic quality. RESULTS: Ten longitudinal-observational studies with comparison group presenting moderate methodologic flaws were included (N = 7820). The combination of results indicates that health-related quality of life is not significantly different between S-ICD and TV-ICD groups (Physical health: MD = 2.90; 95% CI = -3.88, 9.68/Mental health: MD = 0.13; 95% CI = -2.11, 2.37). Mortality occurred in 4.4% of S-ICD patients and 5.9% of TV-ICD patients died (OR = 0.79; 95% CI = 0.50, 1.24). The incidence of infections (OR = 1.79; 95% CI = 0.93, 3.43) and inappropriate shocks (OR = 1.28, 95% CI = 0.91, 1.78) is not significantly different between both groups. The S-ICD reduces complications related to electrodes/leads (OR = 0.13, 95% CI = 0.05, 0.29) and has lower electrodes/leads movement compared with TV-ICD (OR = 0.26; 95% CI 0.10, 0.67). In contrast, pneumothorax is more likely in TV-ICD than S-ICD (OR = 0.17; 95% CI = 0.03, 0.97). CONCLUSIONS: S-ICD reduces electrodes/leads movement, electrodes/leads related complications, and pneumothorax. Our study did not demonstrate a statistically significant difference in mortality, health-related quality of life, and infection rate between S-ICD and TV-ICD.

Effectiveness and cost-effectiveness of a multicomponent intervention to implement a clinical practice guideline for systemic lupus erythematosus: protocol for a cluster-randomized controlled trial.

BACKGROUND: Systemic lupus erythematosus (SLE) is a heterogeneous autoimmune disease with significant potential morbidity and mortality. Substantial gaps have been documented between the development and dissemination of clinical practice guidelines (CPG) and their implementation in practice. The aim of this study is to assess the effectiveness and cost-effectiveness of a multi-component knowledge transfer intervention to implement a CPG for the management of SLE (CPG-SLE). METHODS: The study is an open, multicentre, controlled trial with random allocation by clusters to intervention or control. Clusters are four public university hospitals of the Canary Islands Health Service where rheumatologists are invited to participate. Patients diagnosed with SLE at least one year prior to recruitment are selected. Rheumatologists in intervention group receive a short educational group programme to both update their knowledge about SLE management according to CPG-SLE recommendations and to acquire knowledge and training on use of the patient-centred approach, a decision support tool embedded in the electronic clinical record and a quarterly feedback report containing information on management of SLE patients. Primary endpoint is change in self-perceived disease activity. Secondary endpoints are adherence of professionals to CPG-SLE recommendations, health-related quality of life, patient perception of their participation in decision making, attitudes of professionals towards shared decision making, knowledge of professionals about SLE and use of healthcare resources. Calculated sample size is 412 patients. Data will be collected from questionnaires and clinical records. Length of follow-up will be 18 months. Multilevel mixed models with repeated time measurements will be used to analyze changes in outcomes over time. Cost-effectiveness, from both social and healthcare services perspectives, will be analyzed by measuring effectiveness in terms of quality-adjusted life years gained. Deterministic and probabilistic sensitivity analyses are planned. DISCUSSION: Impact of CPGs in clinical practice could be improved by applying proven value interventions to implement them. The results of this ongoing trial are expected to generate important scientifically valid and reproducible information not only on clinical effectiveness but also on cost-effectiveness of a multi-component intervention for implementation of a CPG based on communication technologies for chronic patients in the hospital setting.

Handling Data Quality Issues to Estimate the Spanish EQ-5D-5L Value Set Using a Hybrid Interval Regression Approach.

BACKGROUND: The Spanish five-level EuroQol five-dimensional questionnaire (EQ-5D-5L) valuation study was the first to use the EuroQol Valuation Technology protocol, including composite time trade-off (C-TTO) and discrete choice experiments (DCE). In this study, its investigators noticed that some interviewers did not fully explain the C-TTO task to respondents. Evidence from a follow-up study in 2014 confirmed that when interviewers followed the protocol, the distribution of C-TTO responses widened. OBJECTIVES: To handle the data quality issues in the C-TTO responses by estimating a hybrid interval regression model to produce a Spanish EQ-5D-5L value set. METHODS: Four different models were tested. Model 0 integrated C-TTO and DCE responses in a hybrid model and models 1 to 3 altered the interpretation of the C-TTO responses: model 1 allowed for censoring of the C-TTO responses, whereas model 2 incorporated interval responses and model 3 included the interviewer-specific protocol violations. For external validation, the predictions of the four models were compared with those of the follow-up study using the Lin's concordance correlation coefficient. RESULTS: This stepwise approach to modeling C-TTO and DCE responses improved the concordance between the valuation and follow-up studies (concordance correlation coefficient: 0.948 [model 0], 0.958 [model 1], 0.952 [model 2], and 0.989 [model 3]). We recommend the estimates from model 3, because its hybrid interval regression model addresses the data quality issues found in the valuation study. CONCLUSIONS: Protocol violations may occur in any valuation study; handling them in the analysis can improve external validity. The resulting EQ-5D-5L value set (model 3) can be applied to inform Spanish health technology assessments.

Validity of the EQ-5D-5L and reference norms for the Spanish population.

BACKGROUND AND OBJECTIVE: The EuroQol 5 dimensions 5 levels (EQ-5D-5L) is the new version of EQ-5D, developed to improve its discriminatory capacity. This study aims to evaluate the construct validity of the Spanish version and provide index and dimension population-based reference norms for the new EQ-5D-5L. METHODS: Data were obtained from the 2011/2012 Spanish National Health Survey, with a representative sample (n = 20,587) of non-institutionalized Spanish adults (≥ 18 years). The EQ-5D-5L index was calculated by using the Spanish value set. Construct validity was evaluated by comparing known groups with estimators obtained through regression models, adjusted by age and gender. Sampling weights were applied to restore the representativeness of the sample and to calculate the norms stratified by gender and age groups. We calculated the percentages and standard errors of dimensions, and the deciles, percentiles 5 and 95, means, and 95% confidence intervals of the health index. RESULTS: All the hypotheses established a priori for known groups were confirmed (P < 0.001). The EQ-5D-5L index indicated worse health in groups with lower education level (from 0.94 to 0.87), higher number of chronic conditions (0.96-0.79), probable psychiatric disorder (0.94 vs 0.80), strong limitations (0.96-0.46), higher number of days of restriction (0.93-0.64) or confinement to bed (0.92-0.49), and hospitalized in the previous 12 months (0.92 vs 0.81). CONCLUSIONS: The EQ-5D-5L is a valid instrument to measure perceived health in the Spanish-speaking population. The representative population-based norms provided here will help improve the interpretation of results obtained with the new EQ-5D-5L.

Clinical and cost-effectiveness analysis of early detection of patients at nutrition risk during their hospital stay through the new screening method CIPA: a study protocol.

BACKGROUND: Malnutrition is highly prevalent in hospitalized patients and results in a worsened clinical course as well as an increased length of stay, mortality, and costs. Therefore, simple nutrition screening systems, such as CIPA (control of food intake, protein, anthropometry), may be implemented to facilitate the patient's recovery process. The aim of this study is to evaluate the effectiveness and cost-effectiveness of implementing such screening tool in a tertiary hospital, consistent with the lack of similar, published studies on any hospital nutrition screening system. METHODS: The present study is carried out as an open, controlled, randomized study on patients that were admitted to the Internal Medicine and the General and Digestive Surgery ward; the patients were randomized to either a control or an intervention group (n = 824, thereof 412 patients in each of the two study arms). The control group underwent usual inpatient clinical care, while the intervention group was evaluated with the CIPA screening tool for early detection of malnutrition and treated accordingly. CIPA nutrition screening was performed upon hospital admission and classified positive when at least one of the following parameters was met: 72 h food intake control < 50%, serum albumin < 3 g/dL, body mass index < 18.5 kg/m2 (or mid-upper arm circumference ≤ 22.5 cm). In this case, the doctor decided on whether or not providing nutrition support. The following variables will be evaluated: hospital length of stay (primary endpoint), mortality, 3-month readmission, and in-hospital complications. Likewise, the quality of life questionnaires EQ-5D-5 L are being collected for all patients at hospital admission, discharge, and 3 months post-discharge. Analysis of cost-effectiveness will be performed by measuring effectiveness in terms of quality-adjusted life years (QALYs). The cost per patient will be established by identifying health care resource utilization; cost-effectiveness will be determined through the incremental cost-effectiveness ratio (ICER). We will calculate the incremental cost per QALY gained with respect to the intervention. DISCUSSION: This ongoing trial aims to evaluate the cost-effectiveness of implementing the malnutrition screening tool CIPA in a tertiary hospital.

Should full adherence be a necessary goal in schizophrenia? Full versus non-full adherence to antipsychotic treatment.

There is solid evidence of negative consequences of non-adherence in schizophrenia, and recently adherence has been defined as taking more than 80% of prescribed medication. However, the clinical relevance of different degrees of adherence in adherent patients has not been studied. We evaluated sociodemographic, clinical, treatment-related and psychopathological variables in 78 adherent outpatients with schizophrenia, who were classified into two groups: full-adherence (100% adherence) and non-full adherence (80-99.9%). Adherence was evaluated using electronic monitoring (MEMS®), and the injection record in case of injectable antipsychotics. Non-full adherence patients showed more extensive delusions and guilt feelings, as well as trends toward greater somatic concern, disorientation, general psychopathology, and lower number of prior psychiatric hospitalizations. These finding suggest that the 'fullness' of adherence to antipsychotic treatment is a relevant issue, impacting the psychopathological state of adherent patients with schizophrenia. We found that a large proportion of patients can achieve full adherence, and while 'adherence' is an appropriate objective to be pursued with non-adherent patients, 'full adherence' should be the goal among adherent patients.

The impact of alpha-1 antitrypsin deficiency alleles on lung cancer survival.

Different studies have shown that carrying an alpha-1 antitrypsin (AAT) deficiency allele is an independent risk factor for developing lung cancer (LC). However, to date, little is known regarding whether carrying a deficiency allele may be a prognostic factor in the evolution of LC. A prospective observational study was carried out which consecutively included patients diagnosed with LC in University Hospital "Nuestra Señora de Candelaria" between December 2017 and August 2020. A blood sample was taken from each of the patients in order to determine both AAT serum concentration and genotype. Based on AAT genotype, patients were divided into the deficiency (Pi*≠MM) or non-deficiency (Pi*=MM) group. One hundred and sixty-four patients were included. The average length of follow-up was 13±10 months. Patients were classified as stage I (4.2%), stage II (8.3%), stage III (31.2%) and stage IV (56.3%), according to tumour, node and metastasis (TNM) staging. Twenty-eight patients (17%) were carriers of a deficiency allele (6 Pi*MS, 1 Pi*MZ, 1 Pi*MMheerlen). No significant differences were found with respect to baseline characteristics between Pi*≠MM and Pi*=MM. Patients in the Pi*≠MM group had a higher risk of death in the first 6 months after the LC diagnosis compared to Pi*=MM subjects (HR =2.04; 95% CI: 1.04-4.0; P=0.038). The presence of an AAT deficiency genotype could be a potential prognostic marker in LC. However, larger studies that justify these findings are needed.

A study protocol of a comparative mixed study of the T-Control catheter.

Background: Foley catheters have been subject to limited development in the last few decades. They fulfil their basic function of draining urine from the bladder but cause other associated problems. T-Control is a new silicone Foley catheter with an integrated fluid control valve whose design aims to reduce the risks associated with bladder catheterization by a multifactorial approach. The general purpose of this study is to determine the effectiveness, comfort, and experience of the patient catheterized with T-Control® compared with patients with a conventional Foley catheter. Study Design: This trial is a mixed-method study comprising a two-arm, pilot comparative study with random allocation to T-Control catheter or traditional Foley catheter in patients with long-term catheterization and a study with qualitative methodology, through discussion groups. Endpoints: The comfort and acceptability of the T-Control® device (qualitative) and the quality of life related to self-perceived health (quantitative) will be analysed as primary endpoints. As secondary endpoints, the following will be analysed: magnitude and rate of infections (symptomatic and asymptomatic); days free of infection; indication of associated antibiotic treatments; determination of biofilm; number of catheter-related adverse events; use of each type of catheterization's healthcare resources; and level of satisfaction and workload of health professionals. Patients and Methods: Eligible patients are male and female adults aged ≥18 years, who require a change of long-term bladder catheter. The estimated sample size is 50 patients. Patient follow-up includes both the time of catheter insertion and its removal or change 4 weeks later, plus the time until the discussion groups take place.

Effectiveness of the T-Control catheter: A study protocol.

Background: Foley catheters have been subject to limited development in the last few decades. They fulfil their basic function of draining urine from the bladder but cause other associated problems. T-Control is a new silicone Foley catheter with an integrated fluid control valve whose design aims to reduce the risks associated with bladder catheterisation by a multifactorial approach. The general purpose of this study is to evaluate the effectiveness and cost-effectiveness of the T-Control catheter versus the Foley-type catheter in patients with Acute Urine Retention (AUR). Study design: This is a pragmatic, open, multicentre, controlled clinical trial with random allocation to the T-Control catheter or a conventional Foley-type catheter in patients with AUR. Endpoints: The magnitude of infections will be analysed as a primary endpoint. While as secondary endpoint, the following will be analysed: rate of symptomatic and asymptomatic infections; days free of infection; quality of life-related to self-perceived health; indication of associated antibiotic treatments; determination of biofilm; number of catheter-related adverse events; use of each type of catheterisation's healthcare resources; level of satisfaction and workload of health professionals and acceptability of the T-Control device as well as the patient experience. Patients and methods: Eligible patients are male adults aged ≥50 years, with AUR and with an indication of bladder catheterisation for at least 2 weeks. The estimated sample size is 50 patients. Patient follow-up includes both the time of catheter insertion and its removal or change 2 weeks later, plus 2 weeks after this time when the patient will be called for an in-depth interview.

A Scoping Review of the Prevalence of Eating Disorders in Spain.

INTRODUCTION: Eating disorders (EDs) are mental health illnesses with a multifactorial origin. At present, no review of indexed publications studying their prevalence in Spain is available. MATERIAL AND METHODS: A scoping review (PROSPERO -CRD42019140884-) was carried out through systematic searches (MEDLINE, EMBASE and PsycINFO) until January 2022. Papers published in Spanish/English analysing the prevalence of EDs in Spain (population < 65 years) were selected. RESULTS: A total of 766 articles were identified (186 eliminated as duplicates). A total of 580 articles were analysed on the basis of title and abstract, and 67 articles were selected for full-text analysis. A total of 37 studies analysed the prevalence of EDs in Spain. CONCLUSIONS: This is the first scoping review to analyse the prevalence of EDs in Spain. Puberty and adolescence are the most extensively studied stages. There is a high heterogeneity in the use of ED screening tools and a paucity of information on diagnostic tools.

Preliminary assessment of the degree of food addiction through the Spanish Yale Food Addiction Scale for Children (S-YFAS-C) in a pilot pediatric population.

INTRODUCTION: The Spanish Yale Food Addiction Scale for Children (S-YFAS-C) scale is the first tool adapted to Spanish to evaluate food addiction (FA) in the paediatric population. The aim of this study is to preliminarily evaluate the degree of FA in a non-clinical pilot paediatric population. MATERIAL AND METHODS: A transversal observational study was performed on a convenience sample comprised of boys and girls aged 9 to 12 (4th to 6th year primary school). The main outcome measures were evaluation of FA (S-YFAS-C scale), child feeding attitudes (ChEAT scale) and evaluation of body image (CDRS scale). Moreover, sociodemographic and anthropometric data were collected. A descriptive and bivariate analysis of the main characteristics of subjects and outcome measures was performed. RESULTS: A total of 21 boys and 24 girls were preliminarily evaluated and the minimum and maximum values obtained were for age (9.48-12.33), weight in kilograms (26.6-64.5), height in centimetres (131-163), BMI (14.2-27.9) and BMI Z-score (-1.36-2.66). The average number of FA symptoms measured with the S-YFAS-C scale is 1.67 ± 1.45 (range 0-7). A total of 20% of the sample shows three or more symptoms for FA, risk of developing a food disorder and distortion of the body image. Moreover, statistically significant differences were observed between desired body image in boys and girls (P = 0.001). CONCLUSIONS: The S-YFAS-C scale enables evaluating food addiction in Spanish-speaking boys and girls. The data obtained in regard to quantifying symptoms are similar compared to the original scale (S-YFAS-C: 1.67 ± 1.45 vs. YFAS-C: 2 ± 1.81). The option to score the counting of symptoms is the most sensitive measure to evaluate subclinical food behaviours.

Pilot Study on the Relationship between Malnutrition and Grip Strength with Prognosis in Diabetic Foot.

Sarcopenia and malnutrition have been associated in the elderly population with a poor prognosis in wound healing and with other adverse events, such as institutionalization or functional impairment. However, it is not known how these factors influence the prognosis of diabetic foot in the elderly. To answer this question, a prospective observational study of 45 patients over 65 years of age admitted with diagnoses of diabetic foot in a tertiary hospital has been conducted. All patients were assessed at admission and at 3 months after returning home to determine quality of life, pain, mobility and healing, overall hospital stay in relation to the presence of malnutrition (measured by BMI, CIPA scale and analytical parameters at admission of serum proteins and albumin), and sarcopenia measured by grip force, among other geriatric syndromes. The results found a relationship between altered sarcopenia and more pain and poorer quality of life, and altered BMI was related to a lower cure rate and worse mobility at follow-up. This study seems to indicate that, in the elderly population with diabetic foot, malnutrition and sarcopenia should be managed at the same time as the treatment of the diabetic foot itself.

[Scalp cooling for the prevention of chemotherapy-induced alopecia: systematic review and meta-analysis.] / Enfriamiento del cuero cabelludo para la prevención de la alopecia secundaria a quimioterapia: revisión sistemática y metanálisis.

OBJECTIVE: Alopecia is one of the most common adverse effects of chemotherapy, having a significant impact on the quality of life of patients who suffer from it. Among the interventions available for its prevention, scalp cooling (SC) is the most widely used. The aim of this study was to assess the efficacy and safety of the use of SC systems during chemotherapy sessions for the prevention or the reduction of the extent of chemotherapy-induced alopecia. METHODS: A systematic review of the literature published up to November 2021 was carried out. Randomized clinical trials were selected. The main outcome measure was alopecia (hair loss>50%) during and after chemotherapy treatment. When possible, a quantitative synthesis of the results was performed through meta-analysis using the Stata v.15.0 software. The risk ratio (RR) of the variable alopecia, was estimated using a random effects model following the Mantel-Haenszel method. Statistical heterogeneity of the results was evaluated graphically and through the test of heterogeneity χ2 and the Higgins I2 statistic. Sensitivity analyses and subgroup analyses were performed. RESULTS: 13 studies were included, with a total of 832 participants (97.7% women). In most studies, the main chemotherapy treatment applied was anthracyclines or the combination of anthracyclines and taxanes. The results obtained indicate that SC prevents alopecia (loss>50%) by 43% compared to the control group (RR=0.57; 95% CI=0.46 to 0.69; k=9; n=494; I2=63.8%). No statistically significant difference was found between the efficacy of automated and non-automated cooling systems (P=0.967). No serious short- or medium-term adverse events related to SC were recorded. CONCLUSIONS: The results suggest that scalp cooling contributes to the prevention of chemotherapy-induced alopecia.

OBJETIVO: La alopecia es uno de los efectos adversos más comunes de la quimioterapia, con un impacto importante sobre la calidad de vida de los/las pacientes que la padecen. Entre las intervenciones disponibles para su prevención, el enfriamiento del cuero cabelludo (ECC) es la que cuenta con un uso más extendido. El objetivo de este estudio fue evaluar la eficacia y la seguridad del uso de sistemas de ECC durante las sesiones de quimioterapia para la prevención o reducción de la extensión de la alopecia secundaria a la quimioterapia. METODOS: Se llevó a cabo una revisión sistemática de la literatura publicada hasta noviembre de 2021. Se seleccionaron ensayos clínicos aleatorizados. La medida de resultado principal fue la alopecia (pérdida de cabello superior al 50%) durante y posteriormente al tratamiento de quimioterapia. Cuando fue posible, se realizó síntesis cuantitativa de los resultados mediante metanálisis con el programa Stata v.15.0. Se estimó el riesgo relativo (RR) de la variable alopecia, utilizando un modelo de efectos aleatorios siguiendo el método de Mantel-Haenszel. La heterogeneidad estadística de los resultados se evaluó gráficamente y mediante el test de la χ2 y el estadístico I2 de Higgins. Se realizaron análisis de sensibilidad y análisis de subgrupos. RESULTADOS: Se incluyeron 13 estudios con un total de 832 participantes (97,7% de mujeres). En la mayoría de los estudios, los agentes quimioterapéuticos principales aplicados fueron las antraciclinas o la combinación de antraciclinas y taxanos. Los resultados obtenidos indican que el ECC reduce la aparición de la alopecia un 43% frente al grupo control (RR=0,57; IC95%=0,46 a 0,69; k=9; n=494; I2=63,8%). No se encontró una diferencia estadísticamente significativa entre la eficacia de sistemas de enfriamiento automatizados y no automatizados (P=0,967). No se registraron eventos adversos graves a corto o medio plazo relacionados con el ECC. CONCLUSIONES: Los resultados sugieren que el ECC contribuye a prevenir la alopecia secundaria a la quimioterapia.
