Evidence of Validity and Reliability for the Spanish Version of the Self-Identified Stage of Recovery.

BACKGROUND: The Self-Identified Stage of Recovery (SISR) () is a scale used to assess both the stage of recovery (SISR-A) and the components of the process of personal recovery (SISR-B). This study aimed to develop the Spanish version of the SISR and obtain evidence of validity and reliability in a sample of 230 users of community mental health services. METHOD: The Spanish version of the SISR was developed following the translation-back translation procedure, with the support of a committee of experienced experts. The SISR was examined in terms of dimensional structure, internal consistency, relationships with other variables (i.e., the Maryland Recovery Assessment Scale [MARS-12] and the Dispositional Hope Scale [DHS]), and temporal stability (n = 66). Differential item functioning (DIF) by gender was analysed. RESULTS: The study confirmed the unidimensionality of the SISR-B and suitable internal consistency of its scores (ω = .83, α = .83). Scores from both SISR-A and SISR-B showed good temporal stability and the SISR-B displayed strong correlations with the MARS-12 (rs = .78) and the DHS (rs = .67). No DIF was found. CONCLUSIONS: This study supports the validity and reliability of the scores of the Spanish version of the SISR.

Student-Led Webinar to Support LGBTQ+ Students Applying to Medical School During the COVID-19 Pandemic.

Lesbian, gay, bisexual, transgender, queer, intersex, asexual, non-binary, two-spirit, and other (LGBTQ+) students are a diverse group with unique and frequently overlooked needs in medical training. The present study was designed to understand the concerns of LGBTQ+ applicants to medical school and examine the effectiveness of a webinar in alleviating concerns. Sixty participants joined webinars discussing the medical school application process with particular attention to concerns pertinent to the LGBTQ+ population. Pre and post surveys were administered to examine webinar effectiveness and participant concerns. Results were analyzed using quantitative and qualitative methods. Pre-medical students reported that the webinar format was helpful for their application process. Specifically, pre- and post-test analyses revealed that the webinar increased both students' preparedness as well as their confidence in disclosing their LGBTQ+ identity or being "out" when applying to medical school. Student-led, online webinars increase LGBTQ+ students' confidence and help address SGM students' concerns about applying to medical school.

[Patients with COPD hospitalized due to COVID-19 in Spain: a comparison between the first and second wave]. / Pacientes con EPOC hospitalizados por COVID-19 en España: comparación entre la primera y la segunda ola.

Objective: This work aimed to compare the characteristics, progress, and prognosis of patients with COPD hospitalized due to COVID-19 in Spain in the first wave with those of the second wave. Material and methods: This is an observational study of patients hospitalized in Spain with a diagnosis of COPD included in the SEMI-COVID-19 registry. The medical history, symptoms, analytical and radiological results, treatment, and progress of patients with COPD hospitalized in the first wave (from March to June 2020) versus those hospitalized in the second wave (from July to December 2020) were compared. Factors associated with poor prognosis, defined as all-cause mortality and a composite endpoint that included mortality, high-flow oxygen therapy, mechanical ventilation, and ICU admission, were analyzed. Results: Of the 21,642 patients in the SEMI-COVID-19 Registry, 6.9% were diagnosed with COPD: 1,128 (6.8%) in WAVE1 and 374 (7.7%) in WAVE2 (p = 0.04). WAVE2 patients presented less dry cough, fever and dyspnea, hypoxemia (43% vs 36%, p < 0.05), and radiological condensation (46% vs 31%, p < 0.05) than WAVE1 patients. Mortality was lower in WAVE2 (35% vs 28.6%, p = 0.01). In the total sample, mortality and the composite outcome of poor prognosis were lower among patients who received inhalation therapy. Conclusions: Patients with COPD admitted to the hospital due to COVID-19 in the second wave had less respiratory failure and less radiological involvement as well as a better prognosis. These patients should receive bronchodilator treatment if there is no contraindication for it.

Desert dust intrusions and their incidence on airborne biological content. Review and case study in the Iberian Peninsula.

Desert dust intrusions cause the transport of airborne particulate matter from natural sources, with important consequences for climate regulation, biodiversity, ecosystem functioning and dynamics, human health, and socio-economic activities. Some effects of desert intrusions are reinforced or aggravated by the bioaerosol content of the air during these episodes. The influence of desert intrusions on airborne bioaerosol content has been very little studied from a scientific point of view. In this study, a systematic review of scientific literature during 1970-2021 was carried out following the standard protocol Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA). After this literature review, only 6% of the articles on airborne transport from desert areas published in the last 50 years are in some way associated with airborne pollen, and of these, only a small proportion focus on the study of pollen-related parameters. The Iberian Peninsula is affected by Saharan intrusions due to its proximity to the African continent and is seeing an increasing trend the number of intrusion events. There is a close relationship among the conditions favouring the occurrence of intrusion episodes, the transport of particulate matter, and the transport of bioaerosols such as pollen grains, spores, or bacteria. The lack of linearity in this relationship and the different seasonal patterns in the occurrence of intrusion events and the pollen season of most plants hinders the study of the correspondence between both phenomena. It is therefore important to analyse the proportion of pollen that comes from regional sources and the proportion that travels over long distances, and the atmospheric conditions that cause greater pollen emission during dust episodes. Current advances in aerobiological techniques make it possible to identify bioaerosols such as pollen and spores that serve as indicators of long-distance transport from remote areas belonging to other bioclimatic and biogeographical units. A greater incidence of desert intrusion episodes may pose a challenge for both traditional systems and for the calibration and correct validation of automatic aerobiological monitoring methods.

Perceptions of change in the environment caused by the COVID-19 pandemic: Implications for environmental policy.

COVID-19 lockdown measures have impacted the environment with both positive and negative effects. However, how human populations have perceived such changes in the natural environment and how they may have changed their daily habits have not been yet thoroughly evaluated. The objectives of this work were to investigate (1) the social perception of the environmental changes produced by the COVID-19 pandemic lockdown and the derived change in habits in relation to i) waste management, energy saving, and sustainable consumption, ii) mobility, iii) social inequalities, iv) generation of noise, v) utilization of natural spaces, and, vi) human population perception towards the future, and (2) the associations of these potential new habits with various socio-demographic variables. First, a SWOT analysis identified strengths (S), weaknesses (W), opportunities (O), and threats (T) generated by the pandemic lockdown measures. Second, a survey based on the aspects of the SWOT was administered among 2370 adults from 37 countries during the period from February to September 2021. We found that the short-term positive impacts on the natural environment were generally well recognized. In contrast, longer-term negative effects arise, but they were often not reported by the survey participants, such as greater production of plastic waste derived from health safety measures, and the increase in e-commerce use, which can displace small storefront businesses. We were able to capture a mismatch between perceptions and the reported data related to visits to natural areas, and generation of waste. We found that age and country of residence were major contributors in shaping the survey participants ´answers, which highlights the importance of government management strategies to address current and future environmental problems. Enhanced positive perceptions of the environment and ecosystems, combined with the understanding that livelihood sustainability, needs to be prioritized and would reinforce environmental protection policies to create greener cities. Moreover, new sustainable jobs in combination with more sustainable human habits represent an opportunity to reinforce environmental policy.

Effectiveness of a recovery workshop implemented in community mental health services in Catalonia (Spain): study protocol for a non-randomized controlled trial.

BACKGROUND: Many countries today are undergoing a paradigm shift in mental health policies towards a recovery-oriented and rights-based approach. From this perspective, self-determination and self-management are fundamental factors for recovery. Despite this shift, there is still a lack of evidence on the effectiveness of training programmes aimed at promoting self-determination and self-management in recovery processes implemented in southern European or Spanish-speaking countries. The aim of this paper is to present a study protocol that evaluates the effectiveness of a 12-session recovery workshop implemented in community mental health services in Catalonia (Spain). METHODS/DESIGN: This is a 12-week follow-up multi-centre non-randomized controlled trial design. At least 160 users will be recruited from 13 Community Rehabilitation Services (CRS) in Catalonia. Eligible participants are adult (≥ 18 years old) users of a CRS, who sign a written consent to participate. The experimental group participates in a recovery workshop, in which people learn to develop and implement their own plan of personal recovery, which includes a Wellness Toolbox, a Maintenance Toolkit, a Personal Growth Plan, a Mirror of Relapses, a Crisis Plan, and a Learning Agenda. The control group participates in the usual activities of the CRS. Data is collected using a questionnaire of sociodemographic characteristics, personal recovery, empowerment, hope and perceived social support. The users' measurements are taken at the baseline and one week after the end of the workshop. The primary outcome measures include the Self-Identified Stage of Recovery and the Maryland Assessment of Recovery in Serious Mental Illness Scale (short version). The secondary outcome measures include the Netherlands Empowerment List, Dispositional Hope Scale, and Multidimensional Scale of Perceived Social Support. Descriptive statistics for characterizing the sample size will be performed. Multivariate analyses for repeated measures designs will be used to evaluate the primary and secondary outcomes. Between-group and within-subject comparisons will be conducted. DISCUSSION: The results of the study will provide information on the usefulness of recovery workshops in a Mediterranean cultural context. Additionally, if this workshop is effective, it will be proposed for inclusion within the portfolio of community mental health services in Catalonia. TRIAL REGISTRATION: ISRCTN11695542 (Registration date: 5 July 2022).

Mapping mad maps and recovery tools developed by mental health service users and survivors of psychiatry: a scoping review.

BACKGROUND: Since 1997, several tools based on the experiences of users and survivors of psychiatry have been developed with the goal of promoting self-determination in recovery, empowerment and well-being. OBJECTIVES: The aims of this study were to identify these tools and their distinctive features, and to know how they were created, implemented and evaluated. METHOD: This work was conducted in accordance with a published Scoping Review protocol, following the Arksey and O'Malley approach and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews. Five search strategies were used, including contact with user and survivor networks, academic database searching (Cochrane, Cumulative Index to Nursing and Allied Health Literature, PsycINFO, PsycARTICLES, SCOPUS, PubMed and Web of Science), grey literature searching, Google Scholar searching and reference harvesting. We focused on tools, elaborated by users and survivors, and studies reporting the main applications of them. The searches were performed between 21 July and 22 September 2022. Two approaches were used to display the data: descriptive analysis and thematic analysis. RESULTS: Six tools and 35 studies were identified, most of them originating in the USA and UK. Thematic analysis identified six goals of the tools: improving wellness, navigating crisis, promoting recovery, promoting empowerment, facilitating mutual support and coping with oppression. Of the 35 studies identified, 34 corresponded to applications of the Wellness Recovery Action Plan (WRAP). All of them, but one, evaluated group workshops implementations. The most common objective was to evaluate symptom improvement. Only eight studies included users and survivors as part of the research team. CONCLUSIONS: Only the WRAP has been widely disseminated and investigated. Despite the tools were designed to be implemented by peers, it seems they have been usually implemented without them as trainers. Even when these tools are not aimed to promote clinical recovery, in practice the most disseminated recovery tool is being used in this way.

Methods for interpolating missing data in aerobiological databases.

Missing data is a common problem in scientific research. The availability of extensive environmental time series is usually laborious and difficult, and sometimes unexpected failures are not detected until samples are processed. Consequently, environmental databases frequently have some gaps with missing data in it. Applying an interpolation method before starting the data analysis can be a good solution in order to complete this missing information. Nevertheless, there are several different approaches whose accuracy should be considered and compared. In this study, data from 6 aerobiological sampling stations were used as an example of environmental data series to assess the accuracy of different interpolation methods. For that, observed daily pollen/spore concentration data series were randomly removed, interpolated by using different methods and then, compared with the observed data to measure the errors produced. Different periods, gap sizes, interpolation methods and bioaerosols were considered in order to check their influence in the interpolation accuracy. The moving mean interpolation method obtained the highest success rate as average. By using this method, a success rate of the 70% was obtained when the risk classes used in the alert systems of the pollen information platforms were taken into account. In general, errors were mostly greater when there were high oscillations in the concentrations of biotic particles during consecutive days. That is the reason why the pre-peak and peak periods showed the highest interpolation errors. The errors were also higher when gaps longer than 5 days were considered. So, for completing long periods of missing data, it would be advisable to test other methodological approaches. A new Variation Index based on the behaviour of the pollen/spore season (measurement of the variability of the concentrations every 2 consecutive days) was elaborated, which allows to estimate the potential error before the interpolation is applied.

Effects of mesoporous SiO2-CaO nanospheres on the murine peritoneal macrophages/Candidaalbicans interface.

The use of nanoparticles for intracellular drug delivery could reduce the toxicity and side effects of the drug but, the uptake of these nanocarriers could induce adverse effects on cells and tissues after their incorporation. Macrophages play a central role in host defense and are responsible for in vivo nanoparticle trafficking. Assessment of their defense capacity against pathogenic micro-organisms after nanoparticle uptake, is necessary to prevent infections associated with nanoparticle therapies. In this study, the effects of hollow mesoporous SiO2-CaO nanospheres labeled with fluorescein isothiocyanate (FITC-NanoMBGs) on the function of peritoneal macrophages was assessed by measuring their ability to phagocytize Candidaalbicans expressing a red fluorescent protein. Two macrophage/fungus ratios (MOI1 and MOI5) were used and two experimental strategies were carried out: a) pretreatment of macrophages with FITC-NanoMBGs and subsequent fungal infection; b) competition assays after simultaneous addition of fungus and nanospheres. Macrophage pro-inflammatory phenotype markers (CD80 expression and interleukin 6 secretion) were also evaluated. Significant decreases of CD80+ macrophage percentage and interleukin 6 secretion were observed after 30 min, indicating that the simultaneous incorporation of NanoMBG and fungus favors the macrophage non-inflammatory phenotype. The present study evidences that the uptake of these nanospheres in all the studied conditions does not alter the macrophage function. Moreover, intracellular FITC-NanoMBGs induce a transitory increase of the fungal phagocytosis by macrophages at MOI 1 and after a short time of interaction. In the competition assays, as the intracellular fungus quantity increased, the intracellular FITC-NanoMBG content decreased in a MOI- and time-dependent manner. These results have confirmed that macrophages clearly distinguish between inert material and the live yeast in a dynamic intracellular incorporation. Furthermore, macrophage phagocytosis is a critical determinant to know their functional state and a valuable parameter to study the nanomaterial / macrophages / Candida albicans interface.

Predicting the Olea pollen concentration with a machine learning algorithm ensemble.

Air pollution in large cities produces numerous diseases and even millions of deaths annually according to the World Health Organization. Pollen exposure is related to allergic diseases, which makes its prediction a valuable tool to assess the risk level to aeroallergens. However, airborne pollen concentrations are difficult to predict due to the inherent complexity of the relationships among both biotic and environmental variables. In this work, a stochastic approach based on supervised machine learning algorithms was performed to forecast the daily Olea pollen concentrations in the Community of Madrid, central Spain, from 1993 to 2018. Firstly, individual Light Gradient Boosting Machine (LightGBM) and artificial neural network (ANN) models were applied to predict the day of the year (DOY) when the peak of the pollen season occurs, resulting the estimated average peak date 149.1 ± 9.3 and 150.1 ± 10.8 DOY for LightGBM and ANN, respectively, close to the observed value (148.8 ± 9.8). Secondly, the daily pollen concentrations during the entire pollen season have been calculated using an ensemble of two-step GAM followed by LightGBM and ANN. The results of the prediction of daily pollen concentrations showed a coefficient of determination (r2) above 0.75 (goodness of the model following cross-validation). The predictors included in the ensemble models were meteorological variables, phenological metrics, specific site-characteristics, and preceding pollen concentrations. The models are state-of-the-art in machine learning and their potential has been shown to be used and deployed to understand and to predict the pollen risk levels during the main olive pollen season.

Mapping mental health recovery tools developed by mental health service users and ex-users: protocol for a scoping review.

INTRODUCTION: Since the emergence in 1997 of the Wellness Recovery Action Plan, a number of other tools developed by users and/or ex-users of mental health services have been published and implemented. All these tools aim to promote self-determination in mental health recovery processes. A scoping review will be carried out in order to (1) identify existing tools, (2) describe their distinctive characteristics and (3) examine how they have been implemented and evaluated. METHODS AND ANALYSIS: The scoping review will be guided by the methodological framework proposed by Arksey and O'Malley and expanded by Levac et al. It will involve, primarily, a literature search of the following electronic databases: Cochrane database, Cumulative Index to Nursing and Allied Health Literature, PsycInfo, PsycArticles, Scopus, PubMed and Web of Science. In addition, the search process will consider grey literature databases. Users, ex-users and survivors organisations and networks will be contacted in order to identify any relevant material. The reference lists of the articles identified through the literature search will be inspected. Finally, hand searches of journals will be conducted in order to increase the confidence in the search. Two main approaches will be used to present the charted data: a descriptive analysis and a thematic analysis. The study will be performed between April and December 2020. The results will be reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. ETHICS AND DISSEMINATION: This study does not require ethical approval because the data used are from publicly available materials. The study results will be disseminated through an article submitted for publication to a scientific journal and presented at relevant conferences. The results will also be shared in future workshops and seminars as part of continuing education programmes for mental health professionals.

Clinical characteristics of patients hospitalized with COVID-19 in Spain: Results from the SEMI-COVID-19 Registry. / Características clínicas de los pacientes hospitalizados con COVID-19 en España: resultados del Registro SEMI-COVID-19.

BACKGROUND: Spain has been one of the countries most affected by the COVID-19 pandemic. OBJECTIVE: To create a registry of patients with COVID-19 hospitalized in Spain, in order to improve our knowledge of the clinical, diagnostic, therapeutic, and prognostic aspects of this disease. METHODS: A multicentre retrospective cohort study, including consecutive patients hospitalized with confirmed COVID-19 throughout Spain. Epidemiological and clinical data, additional tests at admission and at seven days, treatments administered, and progress at 30 days of hospitalization were collected from electronic medical records. RESULTS: Up to June 30th 2020, 15,111 patients from 150 hospitals were included. Their median age was 69.4 years (range: 18-102 years) and 57.2% were male. Prevalences of hypertension, dyslipidemia, and diabetes mellitus were 50.9%, 39.7%, and 19.4%, respectively. The most frequent symptoms were fever (84.2%) and cough (73.5%). High values of ferritin (73.5%), lactate dehydrogenase (73.9%), and D-dimer (63.8%), as well as lymphopenia (52.8%), were frequent. The most used antiviral drugs were hydroxychloroquine (85.6%) and lopinavir/ritonavir (61.4%); 33.1% developed respiratory distress. Overall mortality rate was 21.0%, with a marked increase with age (50-59 years: 4.7%, 60-69 years: 10.5%, 70-79 years: 26.9%, ≥80 years: 46.0%). CONCLUSIONS: The SEMI-COVID-19 Network provides data on the clinical characteristics of patients with COVID-19 hospitalized in Spain. Patients with COVID-19 hospitalized in Spain are mostly severe cases, as one in three patients developed respiratory distress and one in five patients died. These findings confirm a close relationship between advanced age and mortality.

Predicting the start, peak and end of the Betula pollen season in Bavaria, Germany.

Betula pollen is frequently found in the atmosphere of central and northern Europe. Betula pollen are health relevant as they cause severe allergic reactions in the population. We developed models of thermal requirements to predict start, peak and end dates of the Betula main pollen season for Bavaria (Germany). Betula pollen data of one season from 19 locations were used to train the models. Estimated dates were compared with observed dates, and the errors were spatially represented. External validation was carried out with time series datasets of 3 different locations (36years in total). RESULTS: The temperature requirements to detonate the main pollen season proved non-linear. For the start date model (error of 8,75days during external validation), daily mean temperatures above a threshold of 10°C from 28th of February onwards were the most relevant. The peak model (error of 3.58days) takes into account mean daily temperatures accumulated since the first date of the main pollen season in which the daily average temperature exceeded 11°C. The end model (error of 3.75days) takes into account all temperatures accumulated since the start of the main pollen season. CONCLUSION: These models perform predictions that enable the allergic population to better manage their disease. With the established relationship between temperatures and pollen season dates, changes in the phenological behaviour of Betula species due to climate change can be also estimated in future studies by taking into account the different climate scenarios proposed by previous climate change studies.

Prevalence of abdominal aortic aneurysm in patients with high cardiovascular risk. / Prevalencia de aneurisma de aorta abdominal en pacientes con alto riesgo cardiovascular.

BACKGROUND: To determine the prevalence of abdominal aortic aneurysm (AAA) (arterial diameter ≥30mm), in patients with high or very high cardiovascular risk (CVR) and to evaluate their clinical features. PATIENTS AND METHODS: Observational, cross-sectional and multicentric study conducted in Spanish Internal Medicine Services. We enrolled men with age >55years and women >65years who had a high or very high CVR. RESULTS: The study included 659 patients. The prevalence of AAA was 8% (53 patients). 76.9% were male with a mean age of 71±8.7years. The multivariate analysis showed an association between AAA and age (OR: 1.06; 95%CI: 1.02-1.1; P<.01), male sex (OR: 5.6; 95%CI: 1.6-18.8; P=.01), active smoking (OR: 3.22; 95%CI: 1.16-8.93; P=.024) and peripheral arterial disease (OR: 3.51; 95%CI: 1.73-7.09; P<.01). Diabetes mellitus was an independent protective factor (OR: 0.41; 95%CI: 0.22-0.78; P=.06). Those with subaneurysmal dilatation of the abdominal aorta (diameter 25-29.9mm) presented similar features as patients with AAA. CONCLUSIONS: The prevalence of AAA in patients with high CVR is high. Ultrasound screening can be performed by general practitioners. Men >65years with elevated CVR could benefit, particularly in the presence of active smoking or peripheral arterial disease.

Charged hadron fragmentation functions from collider data: NNPDF Collaboration.

We present NNFF1.1h, a new determination of unidentified charged-hadron fragmentation functions (FFs) and their uncertainties. Experimental measurements of transverse-momentum distributions for charged-hadron production in proton-(anti)proton collisions at the Tevatron and at the LHC are used to constrain a set of FFs originally determined from electron-positron annihilation data. Our analysis is performed at next-to-leading order in perturbative quantum chromodynamics. We find that the hadron-collider data is consistent with the electron-positron data and that it significantly constrains the gluon FF. We verify the reliability of our results upon our choice of the kinematic cut in the hadron transverse momentum applied to the hadron-collider data and their consistency with NNFF1.0, our previous determination of the FFs of charged pions, kaons, and protons/antiprotons.

Positioning document on incorporating point-of-care ultrasound in Internal Medicine departments. / Documento de posicionamiento sobre la incorporación de la ecografía clínica en los servicios de Medicina Interna.

This positioning document describes the most important aspects of clinical ultrasonography in the internal medicine setting, from its fundamental indications to the recommended training period. There is no question as to the considerable usefulness of this tool in the standard clinical practice of internists in numerous clinical scenarios and settings (emergencies, hospital ward, general and specific consultations and home care). Ultrasonography has a relevant impact on the practitioner's ability to resolve issues, increasing diagnostic reliability and safety and providing important information on the prognosis and progression. In recent years, ultrasonography has been incorporated as a tool in undergraduate teaching, with excellent results. The use of ultrasonography needs to be widespread. To accomplish this, we must encourage structured training and the acquisition of equipment. This document was developed by the Clinical Ultrasonography Workgroup and endorsed by the Spanish Society of Internal Medicine.

Differential effects of graphene oxide nanosheets on Candida albicans phagocytosis by murine peritoneal macrophages.

Macrophages, as effector cells involved in the innate and adaptive immunity, play a key role in the response to nanomaterials as graphene oxide (GO) and in their cellular uptake. The interactions at the interface of GO nanosheets, macrophages and microbial pathogens need to be assessed to determine the possible impairment of the immune system induced by biomedical treatments with this nanomaterial. Here, we have evaluated by flow cytometry and confocal microscopy the ability of murine peritoneal macrophages to phagocytose the fungal pathogen Candida albicans, alive or heat-killed, after treatment with poly(ethylene glycol-amine)-derivatized GO nanosheets (PEG-GO). After GO treatment, differences in fungal phagocytosis were observed between macrophages that had taken up GO nanosheets (GO+ population) and those that had not (GO- population). GO treatment increased the ingested alive yeasts in GO- macrophages, whereas phagocytosis diminished in the GO+ population. Ingestion of heat-killed yeasts was slightly higher in both GO- and GO+ populations when comparing with control macrophages. For the first time, we show that GO uptake by macrophages modulates its phagocytic capability, affecting differentially the subsequent ingestion of either alive or heat-killed yeasts. Enhanced ingestion of heat-killed yeast by GO-treated macrophages suggests a beneficial role of this nanomaterial for the clearance of dead microorganisms during infection.
