Fisheries and reproductive biology of Octopus vulgaris (Mollusca: Cephalopoda) in the Gulf of Alicante (Northwestern Mediterranean)

The common octopus Octopus vulgarisCuvier, 1797 is the most fished cephalopod species along the Spanish coasts. Its catches are highly fluctuating due to the short life cycle of the species and to the annual variability of the recruitment pattern, strongly dependent on the environmental conditions affecting the eggs and paralarvae. This study examines the common octopus fishery, the catch composition, and the main features of the reproductive biology of this species in the Gulf of Alicante (Spanish Eastern coast, Western Mediterranean FAO division 37.1.1). The common octopus fishery was studied analysing the monthly landing and effort data by fishing gear from 1994 to 2005. Monthly samplings of the commercial O. vulgarislandings from trawlers and clay pots from January 2004 to December 2005 resulted in the measuring of 1833 specimens to enable analysis of the catch composition, and allowed the biological sampling of 1176 individuals to provide the reproductive parameters of the species in the study area. The length-weight relationship calculated for the species was BW = 0.51 * DML 2.87. The yearly sex ratios (males:females) were 1:1 (trawl, 2004), 1:0.74 (trawl, 2005), and 1:0.88 (clay pots, 2005). The size (dorsal mantle length, DML) at maturity of the species in the study area was 9.67 cm for males and 14.38 cm for females. The gonadosomatic index reached a peak between April and July for males and in July for females. The Fulton condition index was lower in both sexes between June and September, and for males in November-December, whereas for both sexes the values of the digestive gland index were at their maximum between June and December. The energy allocation between somatic and reproductive growth was investigated and the results suggested that the energy spent on reproduction mainly came from feeding, and not from energy stored in the mantle tissues or in the digestive glan

Cost-effectiveness analysis of anti–IL-5 therapies of severe eosinophilic asthma in Spain

Asma eosinofílica greu; Comparació indirecta del tractament; MepolizumabSevere eosinophilic asthma; Indirect treatment comparison; MepolizumabAsma eosinofílica severa; Comparación de tratamiento indirecto; MepolizumabAim To analyse the cost-effectiveness of MEP with standard of care (SoC) versus other anti-IL-5 therapies approved for the treatment of severe eosinophilic asthma (SEA) patients, within the Spanish National Health System (NHS) perspective. Methods A Markov model with a 4-week cycle length was used to compare MEP with BEN and RES as therapies added to SoC in the management of SEA, in terms of cost per QALY gained and incremental cost-effectiveness ratio (ICER). Costs (€2019) were obtained from public sources, while utilities and transition probabilities were retrieved from literature, e.g. network meta-analysis. Continuation criteria for biological treatment and reduction of oral corticosteroids (OCS) was set at 50% minimum reduction of exacerbation rate. Adverse events related to chronic OCS use included diabetes, osteoporosis, cataracts, acute myocardial infarct, and peptic ulcer. The analysis was performed over a 5-year time horizon from the National Healthcare System (NHCS) perspective, with a yearly discount rate of 3% applied to both costs and QALYs. Probabilistic sensitivity analysis and univariate deterministic sensitivity analysis were performed to address uncertainty around the cost-effectiveness results. Results On top of SoC, the model indicates that MEP is dominant (lower cost, higher benefit) compared to BEN and RES: For BEN and RES, respectively, treatment with MEP had a point estimate of 0.076 and 0.075 additional QALYs, and savings of €3,173.47 and €7,772.95 per patient. The findings were robust to variation as estimated using sensitivity analysis. Conclusions MEP is a cost-effective treatment in comparison with BEN and RES added to SoC for patients with SEA in the Spanish setting.This study was funded by GlaxoSmithKline [Study code: HO-19-19968]

Trends in adult asthma hospitalization: gender-age effect

BACKGROUND: Hospital admissions due to asthma are a reliable source of information on the morbidity of the disease which, after the increase observed in the last quarter of the last century, shows a declining trend in the last few years. The aim of this study was to look at hospital admission trends due to asthma in our community and analyze some of its associated factors. METHODS: Retrospective analysis of all hospital admissions involving adults aged 15 years and older with asthma as the primary or secondary diagnosis (if the first diagnosis was respiratory failure or respiratory infection) in Public Health Service hospitals in the Galician region of Spain between the years 1995-2009 (total 24,766 admissions). RESULTS: The majority of patients admitted were female (71%), over 60 years of age (64%), and admission occurred predominantly in the winter months. The hospitalization rate due to asthma tripled over the period studied, this being mainly accounted for by women aged over 60 years. Mean hospital stay was 9.2 days, longer in older patients or those admitted over the weekend. CONCLUSIONS: A significant increase in hospital admissions due to asthma over the last few years has been observed in our community, mainly involving older women. The mean stay seems long, increasing with patients' age and admission over the weekend

Influence of the environment on the characteristics of asthma

Environmental sciences; Health careCiències ambientals; Atenció sanitàriaCiencias Ambientales; Atención sanitariaFew studies have compared the prevalence of asthma in urban and rural settings or explored the issue of whether these two manifestations of the disease may represent different phenotypes. The aim of this study was: (a) to establish whether the prevalence of asthma differs between rural and urban settings, and b) to identify differences in the clinical presentation of asthma in these two environments. Descriptive epidemiological study involving individuals aged 18 or over from a rural (n = 516) and an urban population (n = 522). In the first phase, individuals were contacted by letter in order to organize the administration of a first validated questionnaire (Q1) designed to establish the possible prevalence of bronchial asthma. In the second phase, patients who had presented association patterns in the set of variables related to asthma in Q1 completed a second validated questionnaire (Q2), designed to identify the characteristics of asthma. According to Q1, the prevalence of asthma was 15% (n = 78) and 11% (n = 59) in rural and urban populations respectively. Sixty-five individuals with asthma from the rural population and all 59 individuals from the urban population were contacted and administered the Q2. Thirty-seven per cent of the individuals surveyed had previously been diagnosed with bronchial asthma (35% in the rural population and 40% in the urban setting). In the urban asthmatic population there was a predominance of women, a greater personal history of allergic rhinitis and a family history of allergic rhinitis and/or eczema. Asthma was diagnosed in adulthood in 74.8% of the patients, with no significant differences between the two populations. Regarding symptoms, cough (morning, daytime and night) and expectoration were more frequent in the urban population. The prevalence of asthma does not differ between urban and rural settings. The differences in exposure that characterize each environment may lead to different manifestations of the disease and may also affect its severity.MJC is supported by the Miguel Servet program of the Instituto de Salud Carlos III (MSII17/00025).

Young man with asthma and infertility

occur in the same patient. In some cases they could have patho-physiological changes common to both diseases. Our patient was seen as a result of having an irritating cough with wheezing, mainly at night, for more than a month. Asthma was diagnosed, and he responded favourably to the treatment given. Upon being informed that he had been examined for infertility for 5 years, alpha-1 antitrypsin (AAT) levels were requested. These confirmed that he had a phenotype SZ AAT deficiency. These findings, together with some evidence published recently, suggested that there is a need to rule out AAT deficiency in males with asthma and infertility

Trends in prevalence and the effects on hospital outcomes of dementia in patients hospitalized with acute COPD exacerbation

Aims: To assess changes in prevalence and the effects on hospital outcomes of dementia among patients hospitalized with an acute exacerbation of chronic obstructive pulmonary disease (AE-COPD); and to evaluate sexdifferences, as well as the impact of COVID-19 pandemic in this relationship. Methods: We used a nationwide discharge database to select patients admitted with AE-COPD in Spain from 2011 to 2020. We identified those with any type of dementia, vascular dementia (VaD) or Alzheimer’s disease (AD). Results: We identified 658,429 hospitalizations with AE-COPD (4.45% had any type of dementia, 0.79% VaD and 1.57% AD). The presence of any type of dementia remained stable from 2011 to 2015, and increased significantly between 2016 and 2020. For VaD, the time trend showed no change until 2020, when a significant increment was found. The probability of AD decreased significantly overtime. The in-hospital mortality (IHM) among patients with any type of dementia remained stable overtime until 2020, when it increased significantly. Older age, higher comorbidity, COVID-19, and use of mechanical ventilation were variables associated to IHM. Women had lower risk of dying in the hospital than men in all subgroups. Conclusions: After a previous period of stability, the prevalence of any type of dementia increased over the last 5 years of the study, although we identified different trends depending on the specific cause of dementia. The IHM remained stable overtime until 2020, when it increased, probably related to the COVID-19 pandemic. It is remarkable the protective effect of female sex for IHM.Depto. de Salud Pública y Materno - InfantilFac. de MedicinaTRUEResearch Aid 2022Sociedad Madrileña de Neumología y Cirugía de Tórax (NEUMOMADRID)Comunidad de MadridUniversidad Complutense de Madrid.

A Study of the Prevalence of Asthma in the General Population in Spain

Asma; Epidemiología; PrevalenciaAsthma; Epidemilogy; PrevalenceAsma; Epidemiologia; PrevalençaIntroducción El asma es una enfermedad con elevada prevalencia, que afecta a todos los grupos de edad y genera elevados costes sociosanitarios. Estudios realizados en diversas poblaciones muestran gran variabilidad en su prevalencia, incluso en poblaciones cercanas geográficamente, con datos que sugieren una influencia relevante de factores socioeconómicos. Actualmente en población adulta de España no disponemos de datos poblacionales fiables sobre la prevalencia de esta enfermedad. Los objetivos de este estudio son estimar la prevalencia de asma en población española de 18-79 años, describir la variabilidad entre comunidades autónomas, estimar la prevalencia de infra y sobrediagnóstico, prevalencia de asma no controlada, de asma córticodependiente, conocer el consumo de recursos sanitarios, identificar los fenotipos más frecuentes y establecer un punto de partida para evaluar la tendencia temporal con estudios posteriores. Material y métodos Se realizará un estudio transversal, bietápico, incluyendo pacientes de 50 áreas sanitarias. El estudio se desarrollará en tres fases: 1) cribado y confirmación en historia clínica, en la cual se identificarán los pacientes con diagnóstico previo correctamente establecido de asma; 2) diagnóstico de asma, evaluando a los pacientes en los cuales no está claro el diagnóstico de asma con los datos disponibles en la historia clínica; 3) caracterización del asma, analizando las características de estos pacientes e identificando los fenotipos más frecuentes. Discusión Parece necesario y factible realizar un estudio epidemiológico del asma en España que permita identificar la prevalencia de asma, optimizar la planificación sanitaria, caracterizar los fenotipos más frecuentes de la enfermedad y evaluar los diagnósticos erróneos.Introduction Asthma is a disease with high prevalence, which affects all age groups and generates high health and social care costs. Studies carried out in a number of populations show great variability in its prevalence, even in geographically close populations, with data suggesting a relevant influence of socio-economic factors. At present, we do not have reliable data on the prevalence of this disease in the adult population of Spain. The objectives of this study are to estimate the prevalence of asthma in the Spanish population for those aged 18-79, to describe the variability between autonomous communities, to estimate the prevalence of under and overdiagnosis, to analyse the prevalence of uncontrolled asthma and steroid-dependent asthma, to evaluate the health care cost, to identify the most frequent phenotypes and to establish a starting point to evaluate the temporal trend with subsequent studies. Methods A cross-sectional, two-stage study will be carried out, including patients from 50 catchment areas. The study will be carried out in 3 phases: 1) screening and confirmation in the clinical history, in which patients with a previously correctly established diagnosis of asthma will be identified; 2) diagnosis of asthma to evaluate patients without a confirmed or excluded diagnosis; 3) characterization of asthma, where the characteristics of the asthmatic patients will be analysed, identifying the most frequent phenotypes. Discussion It seems necessary and feasible to carry out an epidemiological study of asthma in Spain to identify the prevalence of asthma, to optimize healthcare planning, to characterize the most frequent phenotypes of the disease, and to evaluate inaccurate diagnoses.Este trabajo ha sido financiado por el Foro Autonómico de Asma-SEPAR

Time Trends in Clinical Characteristics and Hospital Outcomes of Hospitalizations for Lung Transplantation in COPD Patients in Spain from 2016 to 2020—Impact of the COVID-19 Pandemic

This study is part of the research funded by: Sociedad Española de Neumología y Cirugía de Tórax (SEPAR), Research Aid 2022, Project number 1309; and Sociedad Madrileña de Neumología y Cirugía de Tórax (NEUMOMADRID), XXII Awards Edition, 2022, and by: Convenio V-PRICIT de la Comunidad de Madrid y la Universidad Complutense de Madrid (“Programa de Excelencia para el Profesorado Universitario” INV.AY.20.2021.1E126), and by: Universidad Complutense de Madrid. Grupo de Investigación en Epidemiología de las Enfermedades Crónicas de Alta Prevalencia en España (970970).(1) Background: To examine the clinical characteristics and hospital outcomes of hospitalization for lung transplantation in COPD patients in Spain from 2016 to 2020; and to assess if the COVID-19 pandemic has affected the number or the outcomes of lung transplantations in these patients. (2) Methods: We used the Spanish National Hospital Discharge Database to select subjects who had a code for COPD (ICD-10: J44) and had undergone a lung transplantation (ICD-10 codes OBYxxxx). (3) Results: During the study period, 704 lung transplants were performed among COPD patients (single 31.68%, bilateral 68.32%). The absolute number of transplants increased with raising rates of 8%, 14% and 19% annually from 2016 to 2019. However, a marked decrease of −18% was observed from 2019 to year 2020. Overall, 47.44% of the patients suffered at least one complication, being the most frequent lung transplant rejection (24.15%), followed by lung transplant infection (13.35%). The median length of hospital stay (LOHS) was 33 days and the in-hospital-mortality (IHM) was 9.94%. Variables associated with increased risk of mortality were a Comorbidity Charlson Index ≥ 1 (OR 1.82; 95%CI 1.08–3.05) and suffering any complication of the lung transplantation (OR 2.14; 95%CI 1.27–3.6). COPD patients in 2020 had a CCI ≥ 1 in a lower proportion than 2019 patients (29.37 vs. 38.51%; p = 0.015) and less frequently suffered any complications after the lung transplantation (41.26 vs. 54.6%; p = 0.013), no changes in the LOHS or the IHM were detected from 2019 to 2020. (4) Conclusions: Our study showed a constant increase in the number of lung transplantations from 2016 to 2019 in COPD patients, with a drop from 2019 to 2020, probably related to the COVID-19 pandemic. However, no changes in LOHS or IHM were detected over time.Depto. de Salud Pública y Materno - InfantilFac. de MedicinaTRUESociedad Española de Neumología y Cirugía de Tórax (SEPAR)Sociedad Madrileña de Neumología y Cirugía de Tórax (NEUMOMADRID)Convenio V-PRICITUniversidad Complutense de MadridUniversidad Complutense de Madrid.

An Extensive Quality Control and Quality Assurance (QC/QA) Program Significantly Improves Inter-Laboratory Concordance Rates of Flow-Cytometric Minimal Residual Disease Assessment in Acute Lymphoblastic Leukemia : An I-BFM-FLOW-Network Report

Monitoring of minimal residual disease (MRD) by flow cytometry (FCM) is a powerful prognostic tool for predicting outcomes in acute lymphoblastic leukemia (ALL). To apply FCM-MRD in large, collaborative trials, dedicated laboratory staff must be educated to concordantly high levels of expertise and their performance quality should be continuously monitored. We sought to install a unique and comprehensive training and quality control (QC) program involving a large number of reference laboratories within the international Berlin-Frankfurt-Münster (I-BFM) consortium, in order to complement the standardization of the methodology with an educational component and persistent quality control measures. Our QC and quality assurance (QA) program is based on four major cornerstones: (i) a twinning maturation program, (ii) obligatory participation in external QA programs (spiked sample send around, United Kingdom National External Quality Assessment Service (UK NEQAS)), (iii) regular participation in list-mode-data (LMD) file ring trials (FCM data file send arounds), and (iv) surveys of independent data derived from trial results. We demonstrate that the training of laboratories using experienced twinning partners, along with continuous educational feedback significantly improves the performance of laboratories in detecting and quantifying MRD in pediatric ALL patients. Overall, our extensive education and quality control program improved inter-laboratory concordance rates of FCM-MRD assessments and ultimately led to a very high conformity of risk estimates in independent patient cohorts.publishersversionPeer reviewe
