Hydroxychloroquine-induced cardiomyopathy: role of cardiac magnetic resonance for the diagnosis and follow-up of a very rare entity-a case report.

Background: Hydroxychloroquine (HCQ) is a disease-modifying antirheumatic used in rheumatological diseases such as systemic lupus erythematosus. Long-term exposure to HCQ results in drug accumulation and predisposes to adverse effects. Case summary: We present the case of a 45-year-old woman with long-term treatment with HCQ who presented to the Emergency Department with acute heart failure. Transthoracic echocardiogram, previously normal, showed severe biventricular hypertrophy and biventricular systolic dysfunction. Cardiac magnetic resonance (CMR) confirmed the previous findings and showed elevated native T1 and T2 values, elevated extracellular volume, and extensive mid-wall late gadolinium enhancement (LGE). Infiltrative cardiomyopathy was suspected, and endomyocardial biopsy performed. Light microscopy showed myocyte hypertrophy and vacuolar change and absence of lymphocytic inflammatory infiltrates. The diagnosis of HCQ-induced cardiomyopathy was established, and the drug was withdrawn. A CMR performed 1 year later showed normal systolic function of both ventricles and normalization of T2 values, reflecting resolution of myocardial oedema. However, severe hypertrophy, elevated native T1 values, and LGE persisted. Discussion: Our case shows that although discontinuation of the drug stops the progression of the disease, established myocardial structural damage persists. Early diagnosis of this entity is therefore essential to improve prognosis.

Management, development and methodology of the Clinical Practice Guidelines and Recommendations of the Spanish Society of Rheumatology.

The Spanish Society of Rheumatology (SER) brings together the majority of Spain's rheumatologists and, among the many services it offers its members, has a Research Unit (RU). This unit provides methodological support to SER members in clinical and epidemiological research, coordinates and carries out research projects, designs and maintains large patient databases, develops qualitative research projects and produces evidence-based medicine (EBM) documents. Through this last activity, the RU of the SER produces clinical practice guidelines and recommendation documents on topics relevant to rheumatology that meet the most demanding methodological standards. The aim of this article is to describe the management process and methodology followed by the UI of the SER to identify the topics of its EBM documents and how it executes and develops its guidelines and recommendations.

BRAF mutational status is associated with survival outcomes in locally advanced resectable and metastatic NSCLC.

BACKGROUND: Immunotherapy-based treatments have demonstrated high efficacy in patients with advanced and locally advanced non-small-cell lung cancer (NSCLC). BRAF mutations affect a small but significant fraction of NSCLC. The efficacy of these therapies in this subgroup of patients is unknown. MATERIALS AND METHODS: Plasma and tissue samples from 116 resectable stage IIIA/B NSCLC patients, included in NADIM and NADIM II clinical trials (NADIM cohort), and from a prospective academic cohort with 84 stage IV NSCLC patients (BLI-O cohort), were analyzed by next-generation sequencing. RESULTS: The p.G464E, p.G466R, p.G466V, p.G469V, p.L597Q, p.T599I, p.V600E (n = 2) BRAF mutations, were identified in four (3.45 %) samples from the NADIM cohort, all of which were cases treated with neoadjuvant chemoimmunotherapy (CH-IO), and four (4.76 %) samples from the BLI-O cohort, corresponding to cases treated with first-line immunotherapy (n = 2) or CH-IO (n = 2). All these patients were alive and had no evidence of disease at data cut-off. Conversely, patients with BRAF wild-type (wt) tumors in the BLI-O cohort had a median progression-free survival (PFS) of 5.49 months and a median overall survival (OS) of 12.00 months (P-LogRank = 0.013 and 0.046, respectively). Likewise, PFS and OS probabilities at 36 months were 60.5 % and 76.1 % for patients with BRAF-wt tumors in the NADIM cohort. The pathological complete response (pCR) rate after neoadjuvant CH-IO in patients with BRAF-positive tumors (n = 4) was 100 %, whereas the pCR rate in the BRAF-wt population was 44.3 % (RR: 2.26; 95 % CI: 1.78-2.85; P < 0.001). CONCLUSION: BRAF mutations may be a good prognostic factor for advanced and locally advanced NSCLC patients undergoing immunotherapy-based treatments.

External validation of three diabetes prediction scores in a Spanish cohort: does adding high risk for depression improve the validation of the FINDRISC score (FINDRISC-MOOD)?

OBJECTIVES: To evaluate the external validity of the FINDRISC, DESIR and ADA risk scores for the prediction of diabetes in a Spanish population aged >45 years and to test the possible improvement of FINDRISC by adding a new variable of high risk of depression when Patient Health Questionnaire-9 (PHQ-9) questionnaire score ≥10 (FINDRISC-MOOD). DESIGN: Prospective population-based cohort study. SETTING: 10 primary healthcare centres in the north of the city of Madrid (Spain). PARTICIPANTS: A total of 1242 participants without a history of diabetes and with 2-hour oral glucose tolerance test (OGTT) plasma glucose <200 mg/dL (<11.1 mmol/L) were followed up for 7.3 years (median) using their electronic health records (EHRs) and telephone contact. PRIMARY AND SECONDARY OUTCOME MEASURES: Diabetes risk scores (FINDRISC, DESIR, ADA), PHQ-9 questionnaire and 2-hour-OGTT were measured at baseline. Incident diabetes was defined as treatment for diabetes, fasting plasma glucose ≥126 mg/dL (≥7.0 mmol/L), new EHR diagnosis or self-reported diagnosis. External validation was performed according to optimal cut-off, sensitivity, specificity and Youden Index. Comparison between diabetes risk scores, including FINDRISC-MOOD (original FINDRISC score plus five points if PHQ-9 ≥10), was measured by area under the receiver operating characteristic curve (AUROC). RESULTS: During follow-up, 104 (8.4%; 95% CI, 6.8 to 9.9) participants developed diabetes and 185 had a PHQ-9 score ≥10. The AUROC values were 0.70 (95% CI, 0.67 to 0.72) for FINDRISC-MOOD and 0.68 (95% CI, 0.65 to 0.71) for the original FINDRISC. The AUROCs for DESIR and ADA were 0.66 (95% CI, 0.63 to 0.68) and 0.66 (95% CI, 0.63 to 0.69), respectively. There were no significant differences in AUROC between FINDRISC-MOOD and the other scores. CONCLUSIONS: The results of FINDRISC-MOOD were like those of the other risk scores and do not allow it to be recommended for clinical use.

Plasma-Based Scaffold Containing Bone-Marrow Mononuclear Cells Promotes Wound Healing in a Mouse Model of Pressure Injury.

Pressure injuries, or pressure ulcers, are a common problem that may lead to infections and major complications, besides being a social and economic burden due to the costs of treatment and hospitalization. While surgery is sometimes necessary, this also has complications such as recurrence or wound dehiscence. Among the newer methods of pressure injury treatment, advanced therapies are an interesting option. This study examines the healing properties of bone marrow mononuclear cells (BM-MNCs) embedded in a plasma-based scaffold in a mouse model. Pressure ulcers were created on the backs of mice (2 per mouse) using magnets and assigned to a group of ulcers that were left untreated (Control, n = 15), treated with plasma scaffold (Plasma, n = 15), or treated with plasma scaffold containing BM-MNC (Plasma + BM-MNC, n = 15). Each group was examined at three time points (3, 7, and 14 days) after the onset of treatment. At each time point, animals were subjected to biometric assessment, bioluminescence imaging, and tomography. Once treatment had finished, skin biopsies were processed for histological and wound healing reverse transcription polymerase chain reaction (RT-PCR) array studies. While wound closure percentages were higher in the Plasma and Plasma + BM-MNC groups, differences were not significant, and thus descriptive data are provided. In all individuals, the presence of donor cells was revealed by immunohistochemistry on posttreatment onset Days 3, 7, and 14. In the Plasma + BM-MNC group, less inflammation was observed by positron emission tomography-computed tomography (PET/CT) imaging of the mice at 7 days, and a complete morphometabolic response was produced at 14 days, in accordance with histological results. A much more pronounced inflammatory process was observed in controls than in the other two groups, and this persisted until Day 14 after treatment onset. RT-PCR array gene expression patterns were also found to vary significantly, with the greatest difference noted between both treatments at 14 days when 11 genes were differentially expressed.

A maternal dorsoventral prepattern revealed by an asymmetric distribution of ventralizing molecules before fertilization in Xenopus laevis.

The establishment of the embryonic dorsoventral axis in Xenopus occurs when the radial symmetry around the egg's animal-vegetal axis is broken to give rise to the typical symmetry of Bilaterians. We have previously shown that the Notch1 protein is ventrally enriched during early embryogenesis in Xenopus laevis and zebrafish and exerts ventralizing activity through ß-Catenin destabilization and the positive regulation of ventral center genes in X. laevis. These findings led us to further investigate when these asymmetries arise. In this work, we show that the asymmetrical distribution of Notch1 protein and mRNA precedes cortical rotation and even fertilization in X. laevis. Moreover, we found that in unfertilized eggs transcripts encoded by the ventralizing gene bmp4 are also asymmetrically distributed in the animal hemisphere and notch1 transcripts accumulate consistently on the same side of the eccentric maturation point. Strikingly, a Notch1 asymmetry orthogonal to the animal-vegetal axis appears during X. laevis oogenesis. Thus, we show for the first time a maternal bias in the distribution of molecules that are later involved in ventral patterning during embryonic axialization, strongly supporting the hypothesis of a dorsoventral prepattern or intrinsic bilaterality of Xenopus eggs before fertilization.

The PREDG study: A randomised controlled trial testing whether an educational intervention can prevent gestational weight gain in women with obesity.

OBJECTIVE: The PREDG trial was designed to study the influence of an educative program on gestational weight gain in women with pregestational obesity. METHODS: Randomized controlled clinical trial (https://www.isrctn.com/ISRCTN61793947) in 169 women with pregestational obesity (BMI ≥30 kg/m2). Women were randomized to participate in a group education program in nutrition and physical activity or conventional follow-up in a specialized Unit of Obesity and Pregnancy. The nutritional intervention was adjusted to prepregnancy BMI and to the physical activity intensity. Quality was based on the Mediterranean diet. Macronutrients were distributed as follows: 50% carbohydrates, 20% protein and 30% fat. Adequate gestational weight gain was defined between 5 and 9 kg (IOM 2009). Mean gestational weight gain was compared between groups by using the T Student test and frequencies of adequate gestational weight gain were compared by using ꓫ2. RESULTS: Gestational weight gain was lower in the intervention group: 8 (4-11) vs 9.2 (6-13) kg, p 0.026. Gestational weight gain was below 9 kg in 24 of 39 (61.5%) women of the intervention vs 10 of 41 (24.4%) of the control group (p 0.001). Regarding obstetric complications, there were 15 (8.3%) cases of gestational diabetes with no differences between the groups. There were 14 of 85 (18.2%) cases of gestational hypertension or preeclampsia in the intervention group compared with 26 of 84 (32.5%) in the control group (p 0.040). With reference to neonatal weight, there were 7 of 82 (8.5%) large for gestational age neonates in the intervention group compared with 15 of 79 (19.2%) in the control group (p 0.050). CONCLUSIONS: A group-based educative and structured intervention results in an adequate weight gain and lower rates of gestational hypertension, preeclampsia and large for gestational age neonates in pregnant women with obesity.

Revisión de medicamentos sin receta con aspartamo: Indicación Farmacéutica segura en fenilcetonuria / Review of non-prescription medicines with aspartame: safe pharmaceutical indication in phenylketonuria

Introducción: La fenilcetonuria es el trastorno hereditario más frecuente del metabolismo de los aminoácidos y su abordaje suele centrarse en die-tas restringidas en fenilalanina, un aminoácido presente en el edulcorante aspartamo habitualmente usado como excipiente en tecnología farmacéutica. Objetivo: El objetivo principal es la revisión de los medicamentos sin receta comercializados en España hasta marzo de 2023 y que contienen aspartamo en su composición. Método: Se realizó una revisión en la base de datos BOT plus de todos los medicamentos comercializados en España que contienen aspartamo. Se seleccionaron solo los MSR. Se consultaron las fichas técnicas en el Centro de información online de medicamentos de la AEMPS (CIMA), y los datos obtenidos se registraron en una tabla. Resultados: Se obtuvieron 570 medicamentos; 58 eran MSR. Cuando exista petición de MSR con aspartamo en pacientes con fenilcetonuria, en el SIF, tras su evaluación, en el 100% de los casos, el farmacéutico aplicando el Servicio de Indicación Farmacéutica podría indicar un MSR alternativo, con el mismo principio activo pero sin aspartamo como excipiente. Conclusiones: La actuación del farmacéutico comunitario para aplicar el SIF es muy importante en pacientes con fenilcetonuria. Existen medicamentos que no requieren prescripción y se pueden indicar en estos pacientes. El farmacéutico debe tener a su disposición las herramientas necesarias que le faciliten el SIF con este tipo de enfermos. (AU)

Introduction: Phenylketonuria is the most common inherited disorder of amino acid metabolism and its management usually focuses on diets restricted in phenylalanine, an amino acid present in the sweet-ener aspartame commonly used as an excipient in pharmaceutical technology. Objective: The main objective is the review of non-prescription medicines marketed in Spain until March 2023 and that contain aspartame in their composition.Methods: A review of all medicines marketed in Spain containing aspartame was carried out in the BOT plus database. Only MSRs were selected. The data sheets were consulted at the AEMPS online medicines information centre (CIMA), and the data obtained were recorded in a table.Results: 570 medicines were obtained; 58 were MSRs. When there is a request for MSRs with aspartame in patients with phenylketonuria, in the SIF, after evaluation, in 100% of the cases, the pharmacist applying the Pharmaceutical Indication Service could indicate an alternative MSR, with the same active ingredient but without aspartame as an excipient.Conclusions: The action of the community phar-macist to apply the SIF is very important in patients with phenylketonuria. There are medicines that do not require a prescription and can be prescribed for these patients. Pharmacists should have the necessary tools at their disposal to facilitate the SIF with this type of patient. (AU)

Many-Body Superradiance and Dynamical Mirror Symmetry Breaking in Waveguide QED.

The many-body decay of extended collections of two-level systems remains an open problem. Here, we investigate whether an array of emitters coupled to a one-dimensional bath undergoes Dicke superradiance. This is a process whereby a completely inverted system becomes correlated via dissipation, leading to the release of all the energy in the form of a rapid photon burst. We derive the minimal conditions for the burst to happen as a function of the number of emitters, the chirality of the waveguide, and the single-emitter optical depth, both for ordered and disordered ensembles. Many-body superradiance occurs because the initial fluctuation that triggers the emission is amplified throughout the decay process. In one-dimensional baths, this avalanchelike behavior leads to a spontaneous mirror symmetry breaking, with large shot-to-shot fluctuations in the number of photons emitted to the left and right. Superradiant bursts may thus be a smoking gun for the generation of correlated photon states of exotic quantum statistics.

Immune Checkpoint Inhibitor-Related Stress Cardiomyopathy: Differential Diagnosis and Key Role of Cardiac Imaging.

A 76-year-old man with stage IV urothelial carcinoma who was receiving atezolizumab presented with dyspnea, elevated cardiac biomarkers, new negative T waves, and left ventricular apical akinesia. Coronary angiography results were normal. Immune checkpoint inhibitor-related myocarditis was suspected, and high-dose corticosteroid treatment was started. Cardiac magnetic resonance showed apical edema, suggesting stress cardiomyopathy. (Level of Difficulty: Beginner.).

ESC Congress 2022 Imaging Highlights.

Cardiac imaging is an ever-evolving area, with imaging parameters and application in constant re-evaluation. This was reflected in many imaging debates and by the increased number of scientific contributions at the European Society of Cardiology Congress in 2022. While clinical trials tried to answer clinical questions related to the performance of different imaging modalities, many high-quality presentations focused on new imaging biomarkers in different scenarios, such as heart failure with preserved ejection fraction, valvular heart disease or long COVID. This highlights the need for the translation of cardiac imaging technology from research interests towards established measures of clinical practice.

Cardiac Imaging Biomarkers in Chronic Kidney Disease.

Uremic cardiomyopathy (UC), the peculiar cardiac remodeling secondary to the systemic effects of renal dysfunction, is characterized by left ventricular (LV) diffuse fibrosis with hypertrophy (LVH) and stiffness and the development of heart failure and increased rates of cardiovascular mortality. Several imaging modalities can be used to obtain a non-invasive assessment of UC by different imaging biomarkers, which is the focus of the present review. Echocardiography has been largely employed in recent decades, especially for the determination of LVH by 2-dimensional imaging and diastolic dysfunction by pulsed-wave and tissue Doppler, where it retains a robust prognostic value; more recent techniques include parametric assessment of cardiac deformation by speckle tracking echocardiography and the use of 3D-imaging. Cardiac magnetic resonance (CMR) imaging allows a more accurate assessment of cardiac dimensions, including the right heart, and deformation by feature-tracking imaging; however, the most evident added value of CMR remains tissue characterization. T1 mapping demonstrated diffuse fibrosis in CKD patients, increasing with the worsening of renal disease and evident even in early stages of the disease, with few, but emerging, prognostic data. Some studies using T2 mapping highlighted the presence of subtle, diffuse myocardial edema. Finally, computed tomography, though rarely used to specifically assess UC, might provide incidental findings carrying prognostic relevance, including information on cardiac and vascular calcification. In summary, non-invasive cardiovascular imaging provides a wealth of imaging biomarkers for the characterization and risk-stratification of UC; integrating results from different imaging techniques can aid a better understanding of the physiopathology of UC and improve the clinical management of patients with CKD.

Antimicrobial properties and biotransforming ability of fungal endophytes from Ficus carica L. (Moraceae).

The endophytic fungal community associated with leaves of Ficus carica L. (Moraceae) from Argentina was investigated. Fifteen fungal isolates were isolated and identified by molecular methods into the genera Alternaria, Cladosporium, Curvularia, Diaporthe, Epicoccum, Myrothecium, Neofusicoccum, Nigrospora, Preussia and Ustilago. Cladosporium cladosporioides and Curvularia lunata were the most frequently isolated species. The fungal metabolic profiles were obtained by automated TLC and NMR and analysed by PC Analysis. Antifungal and antibacterial activity was assessed by bioautographic assays. In addition, the biotransforming ability of the fungal isolates was tested on F. carica extracts. Five isolates (33.3%) exhibited inhibitory activity against at least one of the microorganisms tested. Most of the fungal endophytes were able to metabolise the flavonoid rutin 1, and the coumarin psoralen 3 present in F. carica extracts. Further investigations of the psoralen biotransforming ability performed by the selected endophyte Alternaria alternata F8 showed the accumulation of the 6,7-furan-hydrocoumaric acid derivative 4 as the main biotransformation product. Our results corroborate that F. carica can live symbiotically with rich and diverse endophytic communities adding insights about their ecological interactions.

Prediction of serious complications in patients with pulmonary thromboembolism and solid cancer: Validation of the EPIPHANY Index in a prospective cohort of patients from the PERSEO study.

INTRODUCTION: There is currently no validated score capable of classifying cancer-associated pulmonary embolism (PE) in its full spectrum of severity. This study has validated the EPIPHANY Index, a new tool to predict serious complications in cancer patients with suspected or unsuspected PE. METHOD: The PERSEO Study prospectively recruited individuals with PE and active cancer or receiving antineoplastic therapy from 22 Spanish hospitals. The estimation of the relative frequency θ of complications based on the EPIPHANY Index categories was made using the Bayesian alternative for the binomial test. RESULTS: A total of 900 patients, who were diagnosed with PE between October 2017 and January 2020, were enrolled. The rate of serious complications at 15 days was 11.8%, 95% highest density interval [HDI], 9.8-14.1%. Of the EPIPHANY low-risk patients, 2.4% (95% HDI, 0.8-4.6%) had serious complications, as did 5.5% (95% HDI, 2.9-8.7%) of the moderate-risk participants and 21.0% (95% HDI, 17.0-24.0%) of those with high-risk episodes. The EPIPHANY Index was associated with overall survival (OS) in patients with different risk levels: median OS was 16.5, 14.4, and 4.4 months for those at low, intermediate, and high risk, respectively. Both the EPIPHANY Index and the Hestia criteria exhibited greater negative predictive value and a lower negative likelihood ratio than the remaining models. The incidence of bleeding at 6 months was 6.2% (95% HDI, 2.9-9.5%) in low/moderate-risk vs 12.7% (95% HDI, 10.1-15.4%) in high-risk (p-value = 0.037) episodes. Of the outpatients, serious complications at 15 days were recorded in 2.1% (95% HDI, 0.7-4.0%) of the cases with EPIPHANY low/intermediate-risk vs 5.3% (95% HDI, 1.7-11.8%) in high-risk cases. CONCLUSION: We have validated the EPIPHANY Index in patients with incidental or symptomatic cancer-related PE. This model can contribute to standardize decision-making in a scenario lacking quality evidence.

Stem cell and tissue engineering approaches in pressure ulcer treatment.

CONTEXT: Pressure ulcers or injuries, arise from ischemic damage to soft tissues induced by unrelieved pressure over a bony prominence. They are usually difficult to treat with standard medical therapy and often they recur. In the search for better treatment options, promising alternative forms of treatment are today emerging. Within the field of regenerative medicine, ongoing research on advanced therapies seeks to develop medicinal products based on gene therapy, somatic cell therapy, tissue-engineering and combinations of these. OBJECTIVE: The main objective is to perform an overview of experimental and clinical developments in somatic cell therapy and tissue engineering targeting the treatment of pressure injuries. METHODS: Searching terms as "PRESSURE ULCER", "STEM CELL THERAPY", "TISSUE ENGINEERING" or "WOUND HEALING" were used in combination or alone, including publications refered to basic and clinical research and focusing on articles showing results obtained in a clinical context. A total of 80 references are cited, including 23 references published in the 3 last years. RESULTS: The results suggest that this form of treatment could be an interesting option in patients with difficult-to-treat ulcers as spinal cord injury patients. CONCLUSION: This field of regenerative medicine is very broad and further research is warranted.

Omnidirectional leaky opto-electrical fiber for optogenetic control of neurons in cell replacement therapy.

The pathophysiological progress of Parkinson's disease leads through degeneration of dopaminergic neurons in the substantia nigra to complete cell death and lack of dopamine in the striatum where it modulates motor functions. Transplantation of dopaminergic stem cell-derived neurons is a possible therapy to restore dopamine levels. We have previously presented multifunctional pyrolytic carbon coated leaky optoelectrical fibers (LOEFs) with laser ablated micro-optical windows (µOWs) as carriers for channelrhodopsin-2 modified optogenetically active neurons for light-induced on-demand dopamine release and amperometric real-time detection. To increase the dopamine release by stimulating a larger neuronal population with light, we present here a novel approach to generate µOWs through laser ablation around the entire circumference of optical fibers to obtain Omni-LOEFs. Cyclic voltammetric characterization of the pyrolytic carbon showed that despite the increased number of µOWs, the electrochemical properties were not deteriorated. Finally, we demonstrate that the current recorded during real-time detection of dopamine upon light-induced stimulation of neurons differentiated on Omni-LOEFs is significantly higher compared to recordings from the same number of cells seeded on LOEFs with µOWs only on one side. Moreover, by varying the cell seeding density, we show that the recorded current is proportional to the dimension of the cell population.

Integrative and Collaborative Approach in the Chronic Management of Obesity in Primary and Tertiary Care Setting: Vall Hebron-SAP Muntanya Healthcare Route.

INTRODUCTION: In the context of obesity pandemic, the health care providers involved in the primary care should have a significant role. Several guidelines for the management of obesity in primary care were proposed recently. In general lines, these guidelines include recommendation on the baseline assessment, therapy, and algorithm for referral to specialized obesity clinic and follow-up. Nevertheless, at present, there is no guideline or protocol that continuously and bidirectionally links the two settings: primary care and specialized obesity clinic. METHODS: We present a model of continuous, bilateral, and integrative interaction between primary care units and reference tertiary care setting in the chronic management of obesity that is already implemented in a public health system. RESULTS: The novelty of our algorithm is that incorporates the support and continuous communication with the specialized obesity clinic of the tertiary care setting from the beginning in the management of a patient with obesity, in a bidirectional manner. CONCLUSION: This kind of bidirectional and continuous collaboration will help engage health care providers in the management of obesity, optimize efforts, shorten the time until proper intervention, personalize the approach and, finally, save costs for the health system.

[Prospective observational study of the impact of problems accessing treatment such as risk factors for adherence and persistence. Pilot study]. / Estudio observacional prospectivo del impacto de los problemas de acceso al tratamiento como factores de riesgo de la adherencia y persistencia. Estudio piloto.

Introduction: Some preliminary studies that reveal the onset of risk factors not investigated previously in regard to the health system were performed. They can reduce adherence and/or persistence of pharmacological treatments. Knowledge about them can lead to possible solutions. Aim: To estimate the incidence of risk factors in regard to the health system that can reduce adherence/persistence with treatments associated with problems accessing these in the community pharmacy. Method: Transversal, randomized, prospective study in community pharmacies in Asturias and Aragón regions. The primary endpoint was the incidence of new risk factors that means that the prescription is inadequate for its dispensing. Different subgroups were analyzed according to type of risk factor, population and prescription. Results: The typical patient is a vulnerable person according to his age (65.4 years), multipathology and polypharmacy (6.8 drugs). After the evaluation of 138,697 cases of dispensing in 98 community pharmacies a total of 2009 patients were detected with 2221 cases of dispensing with risk factors in terms of adherence and/or persistence (1.6% of the total dispensing). The type of incidence most commonly observed was expiry of the prescription (54.7%; 95%CI=52.6-56.8), followed by no prescription record (18.7%; 95%CI: 17.1-20.3). For its part supply problems stood at 10.2% (95%CI= 10.6%-10.9%). The most compromised therapeutic groups were groups N Nervous System (27.6%), C Cardiovascular System (20.3%) and A Gastrointestinal System (15.3%). Conclusions: The results obtained suggest that the current incidence of risk factors in regard to the health system in terms of adherence and/or persistence may comprise a health problem with a clinical, quality of life and financial impact. As these risk factors are modifiable, a greater capacity for community pharmaceutical action by means of exceptional dispensing to authorize the treatment's continuity would be an acceptable solution.
