Quercetin ameliorates lipid deposition in primary hepatocytes of the chicken embryo.

1. The accumulation of excessive fat plays a role in the development of non-alcoholic fatty liver disease (NAFLD) and phytogenic feed additives have the potential to ameliorate this. This study involved the isolation and culture of primary hepatocytes from chicken embryos to establish a model of hepatic steatosis induced by oleic acid/dexamethasone (OA/DEX). Lipid accumulation and cell viability were assessed using Nile Red staining, Oil Red O staining and cell count Kit -8 (CCK8) following treatment with varying concentrations of quercetin (Que). The potential mechanism by which Que exerts its effects was preliminarily investigated.2. The results indicated that OA effectively treated lipid accumulation in hepatocytes. There was no notable variance in cell proliferation between the normal and OA/DEX groups when subjected to Que treatment at concentrations of 1000 ng/ml and 10 000 ng/ml. Triglycerides and cholesterol (low and high density) decreased with Que treatment, with the most substantial reduction observed at 10 000 ng/ml.3. Gene expression levels decreased to levels similar to those in the control groups. Western blot data demonstrated that sterol regulatory element-binding protein 1 (SREBP-1) protein expression correlated with its mRNA expression level. Que mitigated lipid accumulation through the alpha serine/threonine protein kinase (AKT) and extracellular signal-regulated kinase (ERK) pathways. Expression levels of lipid-related genes (APOB, PPARα, CYP3A5 and SREBP-1) decreased to levels similar to the control groups. Western blot data demonstrated that the SREBP-1 protein expression correlated with its mRNA expression level.4. Supplementation with Que ameliorated lipid accumulation through AKT and ERK signalling pathway in OA/DEX-induced high-fat hepatocytes.

Effect of quercetin on granulosa cells development from hierarchical follicles in chicken.

1. The bioflavonoid quercetin is a biologically active component, but its functional regulation of granulosa cells (GCs) during chicken follicular development is little studied. To investigate the effect of quercetin on follicular development in laying hens, an in vitro study was conducted on granulosa cells from hierarchical follicles treated with quercetin.2. The effect of quercetin on cell activity, proliferation and apoptosis of granulosa cells was detected by CCK-8, EdU and apoptosis assays. The effect on progesterone secretion from granulosa cells was investigated by enzyme-linked immunosorbent assay (ELISA). Expression of proliferating cell nuclear antigen (PCNA) mRNA and oestrogen receptors (ERs), as well as the expression of steroid acute regulatory protein (StAR), cytochrome P450 cholesterol side chain cleavage enzyme (P450scc) and 3ß-hydroxysteroid dehydrogenase (3ß-HSD) mRNA during progesterone synthesis, were measured by real-time quantitative polymerase chain reaction (RT-qPCR). PCNA, StAR and CYP11A1 protein expression levels were detected using Western blotting (WB).3. The results showed that treatment with quercetin in granulosa cells significantly enhanced cell vitality and proliferation, reduced apoptosis and promoted the expression of gene and protein levels of PCNA. The levels of progesterone secretion increased significantly following quercetin treatment, as did the expression levels of StAR and CYP11A1 using the Western Blot (WB) method.4. The mRNA expression levels of ERα were significantly upregulated in the 100 ng/ml and 1000 ng/ml quercetin-treated groups, while there was no significant difference in expression levels of ERß mRNA.

Fármacos modificadores de la enfermedad en la esclerosis múltiple durante la lactancia: revisión de la evidencia actual / Disease-modifying drugs in multiple sclerosis during breastfeeding: a review of current evidence

Introducción: La esclerosis múltiple afecta principalmente a mujeres en edad fértil, y el período de gestación y posparto es de especial interés por las peculiaridades que comporta en cuanto a evolución de la enfermedad y por las consecuencias terapéuticas que se derivan. En el período de lactancia materna (LM), la elección de la estrategia de tratamiento debe poner en una balanza, por un lado, los beneficios bien establecidos de la LM para el recién nacido y su madre y, por el otro, el perfil de seguridad y potenciales efectos adversos en el lactante derivados de la exposición a los fármacos modificadores de la enfermedad, por transferencia a través de leche materna. Desarrollo: Se realiza una revisión de la evidencia actual acerca de la seguridad de los fármacos modificadores de la enfermedad disponibles para el tratamiento de la esclerosis múltiple durante el período de LM, y se recogen datos de transferencia de los diferentes fármacos a la leche materna, así como los potenciales efectos adversos descritos en el lactante. Los fármacos considerados de primera elección durante este período son el interferón beta y el acetato de glatiramer. El resto de los fármacos modificadores de la enfermedad no están aceptados para su utilización en el período de LM por ficha técnica. Sin embargo, en los últimos años, se han publicado datos de estudios de práctica clínica y series de casos que indican que algunos de estos fármacos podrían utilizarse con seguridad durante este período. Conclusiones: Teniendo en cuenta los beneficios reconocidos de la LM para la salud tanto de la madre como del lactante, se debe recomendar la LM exclusiva a las pacientes con esclerosis múltiple siempre que sea posible. Es fundamental realizar una evaluación individualizada previa al embarazo y valorar las diferentes opciones de tratamiento en función de cada paciente.(AU)

Introduction: Multiple sclerosis mainly affects women of childbearing age, and the pregnancy and postpartum period is of special interest because of the peculiarities of the disease course and the therapeutic consequences that derive from it. During the period of breastfeeding (BF), the choice of treatment strategy must weigh up the well-established benefits of BF for both the newborn and the mother against the safety profile and potential adverse effects on the infant resulting from exposure to disease-modifying drugs transferred through breast milk. Development: The study reviews the current evidence on the safety of disease-modifying drugs available for the treatment of multiple sclerosis during the BF period, and gathers data on the transfer of the different drugs into breast milk, as well as the potential adverse effects described in the infant. The drugs of first choice during this period are interferon beta and glatiramer acetate. The rest of the disease modifying drugs are not accepted for use in the BF period according to their summary of product characteristics. However, in recent years, data from studies of clinical practice and case series have been published suggesting that some of these drugs could be used safely during this period. Conclusions: Given the recognised health benefits of BF for both mother and infant, exclusive breastfeeding is recommended whenever possible. It is essential to carry out an individualised assessment prior to pregnancy and to evaluate the different treatment options depending on each patient.(AU)

Characterizing the features and course of psychiatric symptoms in children and adolescents with autoimmune encephalitis.

Autoimmune encephalitis (AE) can present like a psychiatric disorder. We aimed to illustrate the psychiatric manifestations, course and management of AE in a paediatric cohort. Neuropsychiatric symptoms, investigations and treatment were retrospectively retrieved in 16 patients (mean age 11.31, SD 2.98) with an AE diagnosis at the liaison psychiatry services in two UK tertiary paediatric centres. Psychiatric presentation was characterised by an acute polysymptomatic (predominantly agitation, anger outbursts/aggressiveness, hallucinations, and emotional lability) onset. Antipsychotics produced side effects and significant worsening of symptoms in four cases, and benzodiazepines were commonly used. This psychiatric phenotype should make clinicians suspect the diagnosis of AE and carefully consider use of treatments.

Worldwide use of HPV self-sampling for cervical cancer screening.

An increasing body of evidence supports the validity of self-sampling as an alternative to clinician collection for primary Human Papillomavirus (HPV) screening. Self-sampling effectively reaches underscreened women and can be a powerful strategy in low- and high-resource settings for all target ages. This work aims to summarize the current use of HPV self-sampling worldwide. It is part of a larger project that describes cervical cancer screening programmes and produces standardized coverage estimates worldwide. A systematic review of the literature and official documents supplemented with a formal World Health Organisation country consultation was conducted. Findings show that the global use of HPV self-sampling is still limited. Only 17 (12%) of countries with identified screening programs recommend its use, nine as the primary collection method, and eight to reach underscreened populations. We identified 10 pilots evaluating the switch to self-sampling in well-established screening programs. The global use of self-sampling is likely to increase in the coming years. COVID-19's pandemic has prompted efforts to accelerate HPV self-sampling introduction globally, and it is now considered a key element in scaling up screening coverage. The information generated by the early experiences can be beneficial for decision-making in both new and existing programs.

Subjective voice analysis in patients with muscular tension dysphonia: comparison between clinician and patient evaluation.

BACKGROUND: This study evaluated the correlation between patient and clinician subjective voice analysis in a group of patients suffering from muscular tension dysphonia. This disease does not usually present with organic lesions, and voice analysis is crucial to evaluate it. METHODS: A retrospective study with 75 patients was performed. Correlation between grade, roughness, breathiness, asthenia and strain scale and voice handicap index-10 was analysed. Any possible influence of the type of muscular tension dysphonia on these two scales was studied. RESULTS: There are only a few studies that correlate voice handicap index-10 and the grade, roughness, breathiness, asthenia and strain scale; however, none of them are specific for patients suffering from muscular tension dysphonia. A moderate correlation (r = 0.56) was found. No influence of muscular tension dysphonia type on voice handicap index-10 score was found, but muscular tension dysphonia type 4 had worse grade, roughness, breathiness, asthenia and strain scale scores than other muscular tension dysphonia types. This could be explained if muscular tension dysphonia type 4 is considered to be the most severe form of this disease. CONCLUSION: The use of assessment scales based on the opinion of both the clinician and patient must be considered as complementary clinical tools in order to perform a complete assessment of dysphonia.

OBJETIVOS: Desde el inicio de la pandemia por el virus SARS-CoV2 la Sociedad Española de Neurología (SEN) creó un registro de afectación neurológica para informar al neurólogo clínico. Las encefalopatías y encefalitis fueron una de las complicaciones más descritas. Analizamos las características de las mismas. PACIENTES Y MÉTODOS: Estudio descriptivo retrospectivo, observacional multicéntrico, de pacientes con sintomatología compatible con encefalitis o encefalopatía, introducidos en el Registro SEN COVID-19 desde el 17 de marzo hasta el 6 de junio de 2020. RESULTADOS: Se han registrado 232 casos con síntomas neurológicos, 51 casos de encefalopatía/encefalitis (21,9%). Ningún paciente era trabajador sanitario. Los síndromes más frecuentes fueron: cuadro confusional leve-moderado (33%) y encefalopatía grave o coma (9,8%). El tiempo medio entre el inicio de la infección y la clínica neurológica fue de 8,02 días. Punción lumbar en el 60,8% de pacientes; solo hubo un caso con PCR positiva. Resonancia craneal en el 47% de los pacientes (alterada en el 7,8% de ellos). Se realizó electroencefalograma en el 41,3% de los casos (alterado en el 61,9% de los mismos). CONCLUSIONES: Las encefalopatías y encefalitis son dos de las complicaciones más frecuentes descritas en el SEN COVID-19. Más de un tercio de los pacientes presentó un cuadro de síndrome confusional leve o moderado. El tiempo medio de aparición de la sintomatología neurológica desde el inicio de la infección fue de 8 días (hasta 24 h antes en mujeres que en hombres). El electroencefalograma fue la prueba más sensible en estos pacientes, encontrando muy pocos casos con alteraciones en las pruebas de neuroimagen. Todos los pacientes que recibieron tratamiento con bolos de corticoides o inmunoglobulinas tuvieron una evolución favorable

OBJECTIVES: Since the beginning of the COVID-19 pandemic, the Spanish Society of Neurology has run a registry of patients with neurological involvement for the purpose of informing clinical neurologists. Encephalopathy and encephalitis were among the most frequently reported complications. In this study, we analyse the characteristics of these complications. PATIENTS AND METHODS: We conducted a retrospective, descriptive, observational, multicentre study of patients with symptoms compatible with encephalitis or encephalopathy, entered in the Spanish Society of Neurology's COVID-19 Registry from 17 March to 6 June 2020. RESULTS: A total of 232 patients with neurological symptoms were registered, including 51 cases of encephalopathy or encephalitis (21.9%). None of these patients were healthcare professionals. The most frequent syndromes were mild or moderate confusion (33%) and severe encephalopathy or coma (9.8%). The mean time between onset of infection and onset of neurological symptoms was 8.02 days. Lumbar puncture was performed in 60.8% of patients, with positive PCR results for SARS-CoV-2 in only one case. Brain MRI studies were performed in 47% of patients, with alterations detected in 7.8% of these. EEG studies were performed in 41.3% of cases, detecting alterations in 61.9%. CONCLUSIONS: Encephalopathy and encephalitis are among the complications most frequently reported in the registry. More than one-third of patients presented mild or moderate confusional syndrome. The mean time from onset of infection to onset of neurological symptoms was 8 days (up to 24 hours earlier in women than in men). EEG was the most sensitive test in these patients, with very few cases presenting alterations in neuroimaging studies. All patients treated with boluses of corticosteroids or immunoglobulins progressed favourably

Fontan-associated liver disease. / Enfermedad hepática crónica asociada a la cirugía de Fontan.

OBJECTIVE: To review the pathophysiology of Fontan-associated liver disease, its histologic changes, and its radiologic manifestations. CONCLUSIONS: Fontan-associated liver disease is the result of a set of structural and functional changes in the liver that occur secondary to hemodynamic changes brought about by Fontan surgery. The radiologic manifestations of Fontan-associated liver disease consist of changes in the size and shape of the liver, alterations in the signal intensity or pattern of enhancement, abnormalities in the vascular structures, and focal lesions, which include benign nodules with intense uptake in the arterial phase and hepatocellular carcinoma. Radiologists need to be familiar with this disease and its complications, because the number of patients who undergo Fontan surgery continues to increase, and these patients undergo an increasing number of imaging tests.

Diagnostic accuracy of first-trimester combined screening for early-onset and preterm pre-eclampsia at 8-10 compared with 11-13 weeks' gestation.

OBJECTIVES: To compare the ability of first-trimester combined screening for pre-eclampsia (PE) to predict early-onset and preterm PE when pregnancy-associated plasma protein-A (PAPP-A) and placental growth factor (PlGF) were assessed before vs after 11 weeks' gestation. METHODS: This was a secondary analysis of a prospective cohort study of singleton pregnancies undergoing routine first-trimester screening conducted at Vall d'Hebron University Hospital, Barcelona, Spain, between October 2015 and September 2017. Demographic characteristics, obstetric history, maternal history and biophysical markers (mean uterine artery pulsatility index and mean arterial blood pressure (MAP)) were recorded at the first-trimester scan (at 11 + 0 to 13 + 6 weeks' gestation). Maternal serum concentrations of PAPP-A and PlGF were assessed from the routine first-trimester blood test (at 8 + 0 to 13 + 6 weeks). Women were classified into two groups depending on whether serum biomarkers were assessed at 8 + 0 to 10 + 6 weeks or at 11 + 0 to 13 + 6 weeks. Probability scores for early-onset and preterm PE were calculated by using two different algorithms: the multivariate Gaussian-distribution model and The Fetal Medicine Foundation (FMF) competing-risks model. Receiver-operating-characteristics (ROC) curves were produced and detection rates at fixed 5% and 10% false-positive rates were computed to compare the performance of these algorithms when PAPP-A and PlGF were assessed before vs after 11 weeks. RESULTS: Of the 2641 women included, serum biomarkers were assessed before 11 weeks in 1675 (63.4%) and at or after 11 weeks in 966 (36.6%). Of these, 90 (3.4%) women developed PE, including 11 (0.4%) cases of early-onset PE and 30 (1.1%) of preterm PE. Five (45.5%) cases of early-onset and 16 (53.3%) of preterm PE were identified in the group in which serum biomarkers were assessed at 8 + 0 to 10 + 6 weeks and six (54.5%) cases of early-onset and 14 (46.7%) of preterm PE in the group in which serum biomarkers were assessed at 11 + 0 to 13 + 6 weeks. In the prediction of early-onset and preterm PE using the Gaussian algorithm, no differences were observed between the areas under the ROC curves (AUCs) when PAPP-A and PlGF were measured before or after 11 weeks. In the prediction of early-onset and preterm PE using the FMF algorithm, no differences were observed between AUCs for any of the combinations used for risk calculation when the serum biomarkers were obtained before vs after 11 weeks, except for the combination of PAPP-A and MAP, which showed a greater AUC for the prediction of early-onset PE when PAPP-A was measured at or after 11 weeks. CONCLUSIONS: The prediction of early-onset and preterm PE is similar when serum biomarkers are measured before or after 11 weeks. This allows the use of a two-step approach for PE risk assessment that permits immediate risk calculation at the time of the first-trimester scan. © 2020 The Authors.

Smell and Taste Dysfunction in COVID-19 Is Associated With Younger Age in Ambulatory Settings: A Multicenter Cross-Sectional Study.

BACKGROUND AND OBJECTIVE: Since the initial anecdotal reports of coronavirus disease 2019 (COVID-19) from China, a growing number of studies have reported on smell and/or taste dysfunction (STD). Objective: The aim of our study was to investigate the frequency and severity of STD in COVID-19 patients and to evaluate the association with demographic characteristics, hospital admission, symptoms, comorbidities, and blood biomarkers. METHODS: We performed a multicenter cross-sectional study on patients who were positive for SARS-CoV-2 (n=846) and controls (n=143) from 15 Spanish hospitals. Data on STD were collected prospectively using an in-person survey. The severity of STD was categorized using a visual analog scale. We analyzed time to onset, recovery rate, time to recovery, hospital admission, pneumonia, comorbidities, smoking, and symptoms. RESULTS: STD was at least 2-fold more common in COVID-19-positive patients than in controls. COVID-19-positive hospitalized patients were older, with a lower frequency of STD, and recovered earlier than outpatients. Analysis stratified by severity of STD showed that more than half of COVID-19 patients presented severe loss of smell (53.7%) or taste (52.2%); both senses were impaired in >90%. In the multivariate analysis, older age (>60 years), being hospitalized, and increased C-reactive protein were associated with a better sense of smell and/or taste. COVID-19-positive patients reported improvement in smell (45.6%) and taste (46.1%) at the time of the survey; in 90.6% this was within 2 weeks of infection. CONCLUSION: STD is a common symptom in COVID-19 and presents mainly in young and nonhospitalized patients. More studies are needed to evaluate follow-up of chemosensory impairment.

Pre-eclampsia-like syndrome induced by severe COVID-19: a prospective observational study.

OBJECTIVES: To investigate the incidence of clinical, ultrasonographic and biochemical findings related to pre-eclampsia (PE) in pregnancies with COVID-19, and to assess their accuracy to differentiate between PE and the PE-like features associated with COVID-19. DESIGN: A prospective, observational study. SETTING: Tertiary referral hospital. PARTICIPANTS: Singleton pregnancies with COVID-19 at >20+0  weeks. METHODS: Forty-two consecutive pregnancies were recruited and classified into two groups: severe and non-severe COVID-19, according to the occurrence of severe pneumonia. Uterine artery pulsatility index (UtAPI) and angiogenic factors (soluble fms-like tyrosine kinase-1/placental growth factor [sFlt-1/PlGF]) were assessed in women with suspected PE. MAIN OUTCOME MEASURES: Incidence of signs and symptoms related to PE, such as hypertension, proteinuria, thrombocytopenia, elevated liver enzymes, abnormal UtAPI and increased sFlt-1/PlGF. RESULTS: Thirty-four cases were classified as non-severe and 8 as severe COVID-19. Five (11.9%) women presented signs and symptoms of PE, all five being among the severe COVID-19 cases (62.5%). However, abnormal sFlt-1/PlGF and UtAPI could only be demonstrated in one case. One case remained pregnant after recovery from severe pneumonia and had a spontaneous resolution of the PE-like syndrome. CONCLUSIONS: Pregnant women with severe COVID-19 can develop a PE-like syndrome that might be distinguished from actual PE by sFlt-1/PlGF, LDH and UtAPI assessment. Healthcare providers should be aware of its existence and monitor pregnancies with suspected pre-eclampsia with caution. TWEETABLE ABSTRACT: This study shows that a pre-eclampsia-like syndrome could be present in some pregnancies with severe COVID-19.

Neoplasia papilar intraductal de la vía biliar: radiología en una nueva entidad / Intraductal papillary neoplasm of the bile duct: Radiologic findings in a new disease

La neoplasia papilar intraductal de la vía biliar (NPI-VB) es una entidad poco conocida en nuestro medio por su baja prevalencia. Hasta su nueva definición en la cuarta edición de la clasificación de la Organización Mundial de la Salud de los tumores del aparato digestivo publicada en 2010, la enfermedad se agrupaba bajo una terminología heterogénea y poco precisa. Además, en los últimos años se ha avanzado en el conocimiento de su etiopatogenia, su historia natural y sus hallazgos en imagen. El propósito de este artículo es repasar estos datos subrayando los hallazgos radiológicos de la enfermedad y su diagnóstico diferencial

INTRODUCCIÓN: Desde los informes anecdóticos iniciales de China sobre la enfermedad por coronavirus 2019 (COVID-19), ha habido un número creciente de estudios que describen disfunción del olfato y/o del gusto (DOG). OBJETIVO: El objetivo fue investigar la frecuencia y la gravedad de la DOG en pacientes con COVID-19 y evaluar su asociación con características demográficas, ingreso hospitalario, síntomas, comorbilidades y biomarcadores sanguíneos. MÉTODOS: Estudio transversal multicéntrico en pacientes con SARS-CoV-2 positivo (n=846) y controles (n=143) de 15 hospitales españoles. Los datos de DOG fueron recopilados de manera prospectiva con una encuesta realizada en persona. La gravedad de la DOG se clasificó por escala visual analógica. Se analizaron el tiempo de aparición de DOG, tasa de recuperación, tiempo de recuperación, ingreso hospitalario, diagnóstico de neumonía, comorbilidades, tabaquismo y síntomas. RESULTADOS: La DOG fue al menos 2 veces más común en pacientes COVID-19 en comparación con los controles. Los pacientes hospitalizados con COVID-19 eran mayores, presentaban una menor frecuencia de DOG y se recuperaron antes que los pacientes ambulatorios. El análisis estratificado por gravedad de la DOG mostró que más de la mitad de los sujetos con COVID-19 presentaron pérdida severa del olfato (53,7%) o del gusto (52,2%), en> 90% este deterioro fue de ambos sentidos. En el análisis multivariante, una edad mayor (>60 años), ser hospitalizado y un mayor nivel de proteína C reactiva fueron factores asociados con un mejor sentido del olfato y/o sabor. Los pacientes positivos para COVID-19 informaron una mejoría del olfato (45,6%) y del gusto (46,1%) en el momento de la encuesta, de ellos, un 90,6% en menos de dos semanas después de la infección. CONCLUSIÓN: DOG es un síntoma común en COVID-19, y principalmente presente en pacientes jóvenes y no hospitalizados. Se necesitan más estudios para evaluar el seguimiento de la discapacidad quimio-sensorial

Diagnóstico por imagen de anomalías en el número y localización del bazo / Diagnostic imaging of abnormalities in the number and location of the spleen

En las exploraciones radiológicas abdominales, algunas anomalías del desarrollo, como el bazo accesorio periesplénico, son fácilmente reconocibles debido a su elevada incidencia. Sin embargo, otras menos frecuentes, como el bazo accesorio intrapancreático, la fusión esplenopancreática o esplenogonadal, la heterotaxia y el bazo errante, así como anomalías adquiridas como la esplenosis, pueden plantear dificultades diagnósticas. El propósito de nuestra revisión es mostrar los hallazgos radiológicos y el diagnóstico diferencial de dichas anomalías esplénicas poco habituales

In imaging studies, some developmental anomalies such as perisplenic accessory spleen are easily recognizable due to their high incidence. However, other, less common anomalies such as intrapancreatic accessory spleen, splenopancreatic fusion, splenogonadal fusion, heterotaxy, and wandering spleen, as well as acquired conditions such as splenosis, can pose diagnostic difficulties. This aim of this review is to show the imaging diagnosis and differential diagnoses of these uncommon splenic anomalies

However, other, less common anomalies such as intrapancreatic accessory spleen, splenopancreatic fusion, splenogonadal fusion, heterotaxy, and wandering spleen, as well as acquired conditions such as splenosis, can pose diagnostic difficulties. This aim of this review is to show the imaging diagnosis and differential diagnoses of these uncommon splenic anomalies.

[Perception of surgeons on the use of antimicrobial stewardships programs]. / Percepción de los cirujanos acerca de los programas PROA.

INTRODUCTION: The misuse and overuse of antimicrobials can contribute to an increase in antimicrobial resistance, increasing the risk of infections caused by drug-resistant bacteria. Most common surgical pathologies are infectious (either primary or as a complication), often being over-treated. Exploring the perception of surgeons on the use of implementing Antimicrobial stewardship programs (ASPs) is relevant in order to adapt the program to local context. OBJECTIVE: To determine the perception of surgeons on the management of infections and antibiotic (AB) prescription in a General Surgery Department (GSD). METHODS: A cross-sectional and descriptive study was conducted using an anonymous questionnaire that was distributed to assess the aspects related to AB management. RESULTS: A total of 42 questionnaires were completed, with a 65% response rate. The large majority (75%) considered that antimicrobial resistance was an important problem. The main situations considered with medium/high margin of improvement were: time from taking the specimen to receiving the results (70%), use of a wide spectrum AB, and excessive duration (88% and 89%), dose adjustment according to renal function (81%), unnecessary prolongation of intravenous AB treatment (87%) and excessive duration of it (89%), preference for intravenous AB administration until discharge of the patient (73%). There were also difficulties in ASP implementation, as well as established and solid AB patterns (84%) and the heterogeneity of the GSD (84%). CONCLUSIONS: Organisational aspects of the GSD constitute one of the problems to implement the ASPs. A specific multidisciplinary team has been constituted to address different training aspects. This will also serve as a forum of discussion of certain complex patients with difficulties in antibiotic management.
