Haematological and other manifestations in the presence of antiphospholipid antibodies in a multicentric paediatric cohort.

OBJECTIVES: To identify the variables associated with the development of haematological manifestations in the presence of antiphospholipid antibodies (aPLs) in a paediatric cohort. METHODS: We conducted a multicentric retrospective cohort study of children under the age of 18 years. RESULTS: One hundred and thirty-four children were included; 12.2% had at least one thrombotic event (TE) and 67% at least one non-criterion manifestation. Of them, 90% did not develop any TE. Haematological manifestations were the most frequent (42%), followed by neurological (19.8%), cutaneous (17.6%), cardiac (16.8%) and renal (1.5%) manifestations. In those children with haematological disorders, the aPLs positivity rate was: 67.3% LA, 65.6% aß2GPI, 60% aCL, 45.5% single, 23.6% double and 30.9% triple. A univariate analysis showed that children with IgM aCL+, IgM aß2GPI+, triple positivity and with a SLE diagnosis had a significantly higher frequency of haematological manifestations (p<0.05). Finally, a stepwise regression analysis identified IgG aß2GPI positivity [OR 2.91, 95% CI (1.26-6.74), p=0.013], SLE [OR 2.67, 95% CI (1.13-6.3), p=0.026] and LA positivity [OR 2.53, 95% CI (1.08-5.94), p=0.033] as independent risk factors for the development of haematological manifestations. CONCLUSIONS: Non-criteria manifestations and among them haematological disorders, are the most frequent events in the presence of aPLs and/or LA in our paediatric cohort. Children with SLE, LA and/or IgG aß2GPI positivity showed a higher risk of haematological manifestations.

Cell-penetrating peptide inhibits retromer-mediated human papillomavirus trafficking during virus entry.

Virus replication requires critical interactions between viral proteins and cellular proteins that mediate many aspects of infection, including the transport of viral genomes to the site of replication. In human papillomavirus (HPV) infection, the cellular protein complex known as retromer binds to the L2 capsid protein and sorts incoming virions into the retrograde transport pathway for trafficking to the nucleus. Here, we show that short synthetic peptides containing the HPV16 L2 retromer-binding site and a cell-penetrating sequence enter cells, sequester retromer from the incoming HPV pseudovirus, and inhibit HPV exit from the endosome, resulting in loss of viral components from cells and in a profound, dose-dependent block to infection. The peptide also inhibits cervicovaginal HPV16 pseudovirus infection in a mouse model. These results confirm the retromer-mediated model of retrograde HPV entry and validate intracellular virus trafficking as an antiviral target. More generally, inhibiting virus replication with agents that can enter cells and disrupt essential protein-protein interactions may be applicable in broad outline to many viruses.

Non-criteria manifestations in the presence of antiphospholipid antibodies in a paediatric cohort.

OBJECTIVE: To identify the variables associated with the development of non-criteria manifestations in the presence of antiphospholipid antibodies (aPLs) in a paediatric cohort. METHODS: Multicentric historical cohort study of children under the age of 18 years to determine thrombotic events (TEs) and non-criteria manifestations in the presence of aPL. RESULTS: Eighty-two children were included; 8.5% had at least one TE and 69.5% at least one non-criteria manifestation. Of them, 96.5% did not associate TEs. Haematological manifestations were the most frequent (43.65%), followed by cutaneous (22%), neurological (15.9%) and cardiac (4.9%) events. The most frequent aPLs were: 77.8% LA; 42.7% aCL and 41.5% aß2GP. The positivity rate was: 64.6% simple, 18.3% double and 17.1% triple. ANA positivity was 68.1%. A bivariate analysis revealed that children with IgM aCL+, IgM aß2GP+, ANA+, an SLE diagnosis or the absence of TEs had a significantly higher percentage of non-criteria manifestations (P <0.05). The logistic regression showed family history of autoimmune diseases [odds ratio (OR) 4.26, 95% CI: 0.8, 22.2, P =0.086] and the absence of TEs (OR 17.18, 95% CI: 1.2, 244.6, P =0.03) as independent risk factors of developing non-criteria manifestations. An SLE diagnosis, aPL profile and ANA+ were not identified. CONCLUSION: Non-criteria manifestations were more frequent than TEs. A positive family history of autoimmune diseases and the absence of TEs were associated with a higher risk of developing non-criteria manifestations. Therefore, their inclusion as APS classification criteria should be considered in order to get an improved prognosis in the paediatric population.

Use of chemostat cultures mimicking different phases of wine fermentations as a tool for quantitative physiological analysis.

BACKGROUND: Saccharomyces cerevisiae is the most relevant yeast species conducting the alcoholic fermentation that takes place during winemaking. Although the physiology of this model organism has been extensively studied, systematic quantitative physiology studies of this yeast under winemaking conditions are still scarce, thus limiting the understanding of fermentative metabolism of wine yeast strains and the systematic description, modelling and prediction of fermentation processes. In this study, we implemented and validated the use of chemostat cultures as a tool to simulate different stages of a standard wine fermentation, thereby allowing to implement metabolic flux analyses describing the sequence of metabolic states of S. cerevisae along the wine fermentation. RESULTS: Chemostat cultures mimicking the different stages of standard wine fermentations of S. cerevisiae EC1118 were performed using a synthetic must and strict anaerobic conditions. The simulated stages corresponded to the onset of the exponential growth phase, late exponential growth phase and cells just entering stationary phase, at dilution rates of 0.27, 0.04, 0.007 h-1, respectively. Notably, measured substrate uptake and product formation rates at each steady state condition were generally within the range of corresponding conversion rates estimated during the different batch fermentation stages.Moreover, chemostat data were further used for metabolic flux analysis, where biomass composition data for each condition was considered in the stoichiometric model. Metabolic flux distributions were coherent with previous analyses based on batch cultivations data and the pseudo-steady state assumption. CONCLUSIONS: Steady state conditions obtained in chemostat cultures reflect the environmental conditions and physiological states of S. cerevisiae corresponding to the different growth stages of a typical batch wine fermentation, thereby showing the potential of this experimental approach to systematically study the effect of environmental relevant factors such as temperature, sugar concentration, C/N ratio or (micro) oxygenation on the fermentative metabolism of wine yeast strains.

Large-scale transcriptional profiling and functional assays reveal important roles for Rho-GTPase signalling and SCL during haematopoietic differentiation of human embryonic stem cells.

Understanding the transcriptional cues that direct differentiation of human embryonic stem cells (hESCs) and human-induced pluripotent stem cells to defined and functional cell types is essential for future clinical applications. In this study, we have compared transcriptional profiles of haematopoietic progenitors derived from hESCs at various developmental stages of a feeder- and serum-free differentiation method and show that the largest transcriptional changes occur during the first 4 days of differentiation. Data mining on the basis of molecular function revealed Rho-GTPase signalling as a key regulator of differentiation. Inhibition of this pathway resulted in a significant reduction in the numbers of emerging haematopoietic progenitors throughout the differentiation window, thereby uncovering a previously unappreciated role for Rho-GTPase signalling during human haematopoietic development. Our analysis indicated that SCL was the 11th most upregulated transcript during the first 4 days of the hESC differentiation process. Overexpression of SCL in hESCs promoted differentiation to meso-endodermal lineages, the emergence of haematopoietic and erythro-megakaryocytic progenitors and accelerated erythroid differentiation. Importantly, intrasplenic transplantation of SCL-overexpressing hESC-derived haematopoietic cells enhanced recovery from induced acute anaemia without significant cell engraftment, suggesting a paracrine-mediated effect.

Successful port-a-cath salvage using linezolid in children with acute leukemia.

Central venous catheter (CVC) removal is indicated when persistent catheter-related bloodstream infection (CRBSI) occurs. This is a retrospective study to analyze the use of linezolid as a salvage therapy for CRBSIs due to coagulase-negative Staphylococci in children diagnosed with acute leukemia. Seven treatment courses of linezolid were administrated to six patients with port-type-CRBSI after non-effective intravenous vancomycin or teicoplanin treatment. Simultaneous lock and systemic therapy with linezolid avoided the removal of port-type-CVC in all cases. Treatment with linezolid was an alternative to catheter removal in these patients. Prospective studies are needed to confirm linezolid effectiveness as a salvage treatment in CRBSI.

Intravenous Administration of Umbilical Cord-Derived Mesenchymal Stem Cells (UC-MSC) for Acute Respiratory Distress Syndrome Due to COVID-19 Infection.

The COVID-19 pandemic has posed significant therapeutic challenges in addressing acute respiratory distress syndrome (ARDS). This serious illness has caused numerous fatalities worldwide and has had profound health and economic impacts. Previous studies have shown that mesenchymal stem cells (MSCs) can suppress ARDS. In this case series, we report on the treatment of nine patients with a single intravenous dose of 100 million hypoxic cultured umbilical cord-derived MSCs (UC-MSCs). Following the intravenous administration of UC-MSCs, obtained from the lining of the umbilical cord, longitudinal laboratory analysis revealed a sustained decrease in inflammatory markers and stabilized pulmonary function in eight out of nine patients. UC-MSCs possess immunomodulatory and anti-inflammatory properties, enabling them to attenuate the cytokine storm and potentially aid in lung repair. Importantly, no adverse events associated with the treatment were observed. These findings collectively suggest that a cell-based approach significantly enhances the survival rate of ARDS induced by SARS-CoV-2 and offers a promising treatment option in both preclinical and clinical settings.

VIDIIA Hunter diagnostic platform: a low-cost, smartphone connected, artificial intelligence-assisted COVID-19 rapid diagnostics approved for medical use in the UK.

Introduction: Accurate and rapid diagnostics paired with effective tracking and tracing systems are key to halting the spread of infectious diseases, limiting the emergence of new variants and to monitor vaccine efficacy. The current gold standard test (RT-qPCR) for COVID-19 is highly accurate and sensitive, but is time-consuming, and requires expensive specialised, lab-based equipment. Methods: Herein, we report on the development of a SARS-CoV-2 (COVID-19) rapid and inexpensive diagnostic platform that relies on a reverse-transcription loop-mediated isothermal amplification (RT-LAMP) assay and a portable smart diagnostic device. Automated image acquisition and an Artificial Intelligence (AI) deep learning model embedded in the Virus Hunter 6 (VH6) device allow to remove any subjectivity in the interpretation of results. The VH6 device is also linked to a smartphone companion application that registers patients for swab collection and manages the entire process, thus ensuring tests are traced and data securely stored. Results: Our designed AI-implemented diagnostic platform recognises the nucleocapsid protein gene of SARS-CoV-2 with high analytical sensitivity and specificity. A total of 752 NHS patient samples, 367 confirmed positives for coronavirus disease (COVID-19) and 385 negatives, were used for the development and validation of the test and the AI-assisted platform. The smart diagnostic platform was then used to test 150 positive clinical samples covering a dynamic range of clinically meaningful viral loads and 250 negative samples. When compared to RT-qPCR, our AI-assisted diagnostics platform was shown to be reliable, highly specific (100%) and sensitive (98-100% depending on viral load) with a limit of detection of 1.4 copies of RNA per µL in 30 min. Using this data, our CE-IVD and MHRA approved test and associated diagnostic platform has been approved for medical use in the United Kingdom under the UK Health Security Agency's Medical Devices (Coronavirus Test Device Approvals, CTDA) Regulations 2022. Laboratory and in-silico data presented here also indicates that the VIDIIA diagnostic platform is able to detect the main variants of concern in the United Kingdom (September 2023). Discussion: This system could provide an efficient, time and cost-effective platform to diagnose SARS-CoV-2 and other infectious diseases in resource-limited settings.

Biomass production and alcoholic fermentation performance of Saccharomyces cerevisiae as a function of nitrogen source.

Nitrogen limitation is one of the most common causes for stuck or sluggish fermentation. A broad range of values have been reported as the minimum nitrogen concentration necessary for the completion of alcoholic fermentation. We have analyzed the minimum nitrogen concentration required to yield the maximum biomass (nitrogen reference value) using a microwell plate reader to monitor fermentation with different nitrogen sources and sugar concentrations. The biomass yield was dependent on the amount of available nitrogen, the nature of nitrogen source, and the sugar concentration in the medium. Nevertheless, achieving the maximum biomass was not sufficient to ensure the completion of the alcoholic fermentation, because the fermentation of 280 g sugar L(-1) stuck, regardless of the nature and concentration of nitrogen source. However, a mixture of five amino acids (Leu, Ile, Val, Phe and Thr) as the nitrogen source allowed for maximum sugar consumption. Analysis of cell vitality by impedance showed a significant improvement in the vitality for cells fermenting using this amino acid combination.

MmuPV1-Induced Cutaneous Squamous Cell Carcinoma Arises Preferentially from Lgr5+ Epithelial Progenitor Cells.

Murine papillomavirus, MmuPV1, causes natural infections in laboratory mice that can progress to squamous cell carcinoma (SCC) making it a useful preclinical model to study the role of papillomaviruses in cancer. Papillomavirus can infect cells within hair follicles, which contain multiple epithelial progenitor cell populations, including Lgr5+ progenitors, and transgenic mice expressing human papillomavirus oncogenes develop tumors derived from Lgr5 progenitors. We therefore tested the hypothesis that Lgr5+ progenitors contribute to neoplastic lesions arising in skins infected with MmuPV1 by performing lineage tracing experiments. Ears of 6-8-week-old Lgr5-eGFP-IRES-CreERT2/Rosa26LSLtdTomato mice were treated topically with 4-OH Tamoxifen to label Lgr5+ progenitor cells and their progeny with tdTomato and, 72 h later, infected with MmuPV1. Four months post-infection, tissue at the infection site was harvested for histopathological analysis and immunofluorescence to determine the percentage of tdTomato+ cells within the epithelial lesions caused by MmuPV1. Squamous cell dysplasia showed a low percentage of tdTomato+ cells (7%), indicating that it arises primarily from non-Lgr5 progenitor cells. In contrast, cutaneous SCC (cSCC) was substantially more positive for tdTomato+ cells (42%), indicating that cSCCs preferentially arise from Lgr5+ progenitors. Biomarker analyses of dysplasia vs. cSCC revealed further differences consistent with cSCC arising from LGR5+ progenitor cells.

Human induced pluripotent stem cell lines show stress defense mechanisms and mitochondrial regulation similar to those of human embryonic stem cells.

The generation of induced pluripotent stem cells (iPSC) has enormous potential for the development of patient-specific regenerative medicine. Human embryonic stem cells (hESC) are able to defend their genomic integrity by maintaining low levels of reactive oxygen species (ROS) through a combination of enhanced removal capacity and limited production of these molecules. Such limited ROS production stems partly from the small number of mitochondria present in hESC; thus, it was important to determine that human iPSC (hiPSC) generation is able to eliminate the extra mitochondria present in the parental fibroblasts (reminiscent of "bottleneck" situation after fertilization) and to show that hiPSC have antioxidant defenses similar to hESC. We were able to generate seven hiPSC lines from adult human dermal fibroblasts and have fully characterized two of those clones. Both hiPSC clones express pluripotency markers and are able to differentiate in vitro into cells belonging to all three germ layers. One of these clones is able to produce fully differentiated teratoma, whereas the other hiPSC clone is unable to silence the viral expression of OCT4 and c-MYC, produce fully differentiated teratoma, and unable to downregulate the expression of some of the pluripotency genes during the differentiation process. In spite of these differences, both clones show ROS stress defense mechanisms and mitochondrial biogenesis similar to hESC. Together our data suggest that, during the reprogramming process, certain cellular mechanisms are in place to ensure that hiPSC are provided with the same defense mechanisms against accumulation of ROS as the hESC.

Expression of GFP under the control of the RNA helicase VASA permits fluorescence-activated cell sorting isolation of human primordial germ cells.

The isolation of significant numbers of human primordial germ cells at several developmental stages is important for investigations of the mechanisms by which they are able to undergo epigenetic reprogramming. Only small numbers of these cells can be obtained from embryos of appropriate developmental stages, so the differentiation of human embryonic stem cells is essential to obtain sufficient numbers of primordial germ cells to permit epigenetic examination. Despite progress in the enrichment of human primordial germ cells using fluorescence-activated cell sorting (FACS), there is still no definitive marker of the germ cell phenotype. Expression of the widely conserved RNA helicase VASA is restricted to germline cells, but in contrast to species such as Mus musculus in which reporter constructs expressing green fluorescent protein (GFP) under the control of a Vasa promoter have been developed, such reporter systems are lacking in human in vitro models. We report here the generation and characterization of human embryonic stem cell lines stably carrying a VASA-pEGFP-1 reporter construct that expresses GFP in a population of differentiating human embryonic stem cells that show expression of characteristic markers of primordial germ cells. This population shows a different pattern of chromatin modifications to those obtained by FACS enrichment of Stage Specific Antigen one expressing cells in our previous publication.

Hypoxia promotes efficient differentiation of human embryonic stem cells to functional endothelium.

Early development of mammalian embryos occurs in an environment of relative hypoxia. Nevertheless, human embryonic stem cells (hESC), which are derived from the inner cell mass of blastocyst, are routinely cultured under the same atmospheric conditions (21% O(2)) as somatic cells. We hypothesized that O(2) levels modulate gene expression and differentiation potential of hESC, and thus, we performed gene profiling of hESC maintained under normoxic or hypoxic (1% or 5% O(2)) conditions. Our analysis revealed that hypoxia downregulates expression of pluripotency markers in hESC but increases significantly the expression of genes associated with angio- and vasculogenesis including vascular endothelial growth factor and angiopoitein-like proteins. Consequently, we were able to efficiently differentiate hESC to functional endothelial cells (EC) by varying O(2) levels; after 24 hours at 5% O(2), more than 50% of cells were CD34+. Transplantation of resulting endothelial-like cells improved both systolic function and fractional shortening in a rodent model of myocardial infarction. Moreover, analysis of the infarcted zone revealed that transplanted EC reduced the area of fibrous scar tissue by 50%. Thus, use of hypoxic conditions to specify the endothelial lineage suggests a novel strategy for cellular therapies aimed at repair of damaged vasculature in pathologies such as cerebral ischemia and myocardial infarction.

Employee-Athletes: Exploring the Elite Spanish Athletes' Perceptions of Combining Sport and Work.

Researchers have studied the athletes' dual careers with the aim of helping them to combine the sport and the academic-vocational sphere. Most of this research has addressed the study-sport combination, but there is a lack of studies on the work-sport combination. The main objective of this research was to explore the subjective perceptions of Spanish elite athletes when attempting to combine their careers as professional athletes with a second profession or trade. Further, this study aims to identify the access to facilitating resources and the perception of obstacles and barriers to the development of a dual career. A qualitative approach was chosen to address these research questions. Interpretative phenomenological analysis was carried out on a sample of 18 elite athletes, and the data were collected using semi-structured interviews based on a set of superordinate and subordinate categories. The results showed that the athletes interviewed possessed valuable resources such as the transference of sports values to the work sphere. However, important barriers were highlighted such as the perception of sport institutions as absent entities in the work-sport combination. Thus, the study of this type of dual career seems to be one of the challenges facing the interested scientific community for the coming years.

A Cross-Sectional Survey on Professionals to Assess Health Needs of Newly Arrived Migrants in Spain.

Heightened conflicts and lack of safety due to reasons related to economic, social, ethnic, religious, sexual orientation, political, or nationality matters have increased migratory movements during the last, few decades. Unfortunately, when migrants arrive in new territories, they can face many barriers. For example, in Spain, some migrants have difficulties in accessing health services. The main objective of this study was to describe, from the perspective of social and healthcare professionals, health needs and barriers faced among migrants who recently arrived in Spain when accessing the health system. To accomplish this aim, we carried out a cross-sectional descriptive study using a newly created self-administered questionnaire. Statistical analysis was done using the SPSS 23.00® program. Survey collection was from April 2018 to October 2018, and the cohort comprised a total of 228 professionals. Most participants were females (76%), with an average age of 35 years [interquartile range (IQR) 29.8-43.0]. The most represented profession in the cohort was physician (48%), followed by social care professionals (32%), nursing (11%), and other (8%). Of these individuals, 61% stated having either little or limited knowledge of international migrant health rights, and 94% believed migrants must overcome barriers to receive health services. The four most reported barriers were as follows: language, cultural differences, administrative issues, and fear of being undocumented. Additionally, by order of importance, professionals viewed mental health disorders and infectious diseases as the most common contributors to disease burden in this group. The four most popular strategies implemented by professionals to improve healthcare access further for migrants included intercultural competency training for professionals; access to community health agents; access to translators; and development of health system navigation skills among those newly arrived. Study results suggest that governments should make greater efforts to provide social and healthcare professionals with more effective tools that overcome communication barriers and cultural competence training modules.

Advanced airway management: a descriptive analysis of complications and factors associated with first-attempt intubation failure in prehospital emergency care. / Análisis descriptivo de pacientes que requirieron manejo avanzado de vía aérea en emergencias prehospitalarias: complicaciones y factores asociados al fracaso en el primer intento de intubación.

OBJECTIVES: To analyze the characteristics of prehospital emergency airway management, including complications; to explore predictors of first-attempt failure of orotracheal intubation. MATERIAL AND METHODS: Observational retrospective cohort study of patients requiring orotracheal intubation by the prehospital emergency services of Castile-La Mancha between June 1, 2017, and January 1, 2021. We analyzed patient and procedure characteristics and complications using logistic regression analysis to detect factors that could predict firstattempt intubation failure. RESULTS: A total of 425 patients were included; 417 (98.1%) were intubated successfully, including 326 (76.7%) on the first attempt. Complications occurred in 183 intubations in 94 patients (22.1%). Predictors of first-attempt failure were age over 55 years (odds ratio [OR], 1.94; 95% CI, 1.10-4.23), body mass index over 30 (OR, 9.14; 95% CI, 4.40-19.00), oxygen saturation less than 90% (OR, 3.33; 95% CI, 1.06-10.58), a Glasgow Coma Score between 9 and 13 (OR, 1.58; 95% CI, 1.28-6.9), intubation in a public place (OR, 2.99; 95% CI, 1.42-6.29), intubation done in any other than standing position (OR, 2.09; 95% CI, 1.08-7.25), direct laryngoscopy (OR, 2.39; 95% CI, 1.20- 6.55), use of a stylet (OR, 1.80; 95% CI, 1.40-3.78), and a Cormack-Lehane classification of 2 or higher (OR, 6.50; 95% CI, 3.96-30.68). CONCLUSION: Orotracheal intubation is generally accomplished on the first attempt. Factors associated with first-attempt failure can facilitate tailored approaches to upper airway management.

CONCLUSIONES: El procedimiento de intubación se realizó de forma habitual en el primer intento. Existen factores asociados a FIPI que permiten individualizar el manejo de la VA.

The Influence of Basic Psychological Needs and Passion in Promoting Elite Young Football Players' Development.

Motivational variables and cognitive skills have been identified as important in an athlete's development. The aim of this study is to explore the influence of each basic psychological needs satisfaction on player's development regarding reflection and concentration disruption with the mediation of types of passion in Spanish young elite football players. A total of 487 elite U18 male football players (Mage = 17.43, SD = 0.71) completed measures of basic psychological needs satisfaction, passion for football, reflective thinking, and concentration disruption. Measurement models were defined using exploratory structural equation models. The results provide support for the model, where each psychological needs satisfaction prompted reflection and had a negative influence on concentration disruption with the mediation of harmonious passion. In addition, obsessive passion mediated the positive relationship between competence satisfaction and concentration disruption. Finally, competence and relatedness satisfaction influenced the development of reflection directly and positively and, exclusively, relatedness satisfaction had a negative influence in a direct way on concentration disruption. In sum, our results highlight that (a) the environment of young footballers through psychological needs satisfaction has a positive (i.e., reflection) or negative (i.e., concentration disruption) influence on the field, but only with the mediation of harmonious passion, (b) in a competitive environment, the perception of competence can have a positive influence on concentration disruption, but only with the development of obsessive passion as a mediator, and (c) relatedness satisfaction plays a key role in distinguishing between reflection and concentration disruption.

Analysis of the Athletic Career and Retirement Depending on the Type of Sport: A Comparison between Individual and Team Sports.

The type of sport practiced may shape the athletic career, considered as the period in which an athlete is dedicated to obtaining their maximum performance in one or more sports. The aim of this study was to compare athletic careers and retirement in individual and team sports. Four hundred and ten former elite athletes (38.5 ± 7.6 years) answered an ad hoc questionnaire; 61.5% were men and 38.5% women; 45.1% were from individual sports, while 54.9% were from team sports. It emerged that the age of maximum sports performance and the retirement age occurred significantly later in team sports than in individual sports (U = 15,042 and U = 12,624.5, respectively p < 0.001). Team sports athletes combined their athletic career with work to a greater extent than those from individual sports (χ2 (3, N = 408) = 14.2; p = 0.003; Cv = 0.187). Individual sports athletes trained more hours per week (30.0 ± 11.7 h) than those involved in team sports (19.2 ± 10.7 h; U = 9682; p < 0.001). These athletes (team sports) were in a better economic and working situation at retirement transition (χ2 (3, N = 406) = 23.9; p < 0.001; Cv = 0.242). Individual sports athletes perform physical activity more frequently than team sports athletes (U = 16,267.5; p = 0.045), while team sports athletes participate more actively in veteran competitions (χ2 (1, N = 390) = 3.9; p = 0.047; Cv = 0.104) and more frequently attend events as spectators (χ2 (1, N = 390) = 8.4; p = 0.004; Cv = 0.151). dual career support providers should be aware that team sports athletes enjoy a longer athletic career, and they are in a better position to face the retirement transition than individual sports athletes.

Mobile Intensive Care Unit versus Hospital walk-in patients, in the treatment of first episode ST- elevation myocardial infarction.

OBJECTIVE: To determine the impact of the attention given by emergency medical services teams working in mobile intensive care units (MICU) versus patients arriving at the hospital under their own means with ST-elevation myocardial infarction (STEMI) event in terms of time to reperfusion (TR), mortality at 30 days and six months. METHODS: We retrospectively studied 634 consecutive patients with STEMI who underwent primary a percutaneous coronary intervention from January 1st 2015 to December 31st 2018 in a single centre. Depending on the first medical contact patients were classified into two groups, MICU versus walk-in patients. We extracted data on patients' characteristics, symptoms, treatments, times to reperfusion and mortality. RESULTS: In our study 634 patients were included, of whom 59.0% were initially attended by the MICU. Differences were seen between the two groups in time delays to the first medical contact (120.0 vs 63.0 min; p < 0.001) and TR (208.0 Vs 150.0 min; p < 0.001). Patients attended by the MICUs presented a shorter ICU and hospital stay. The lowest 30-day mortality rate was observed in MICU group: 9.0% in contrast with 4.5%, p = 0.03; remaining after 6 months. The multivariable analysis showed that the initial attention given by MICU to STEMI patients was a protective agent against mortality [OR: 0.32 (0.11-0.90); p = 0.03]. CONCLUSION: Initial attention of the patients with STEMI by doctor-on-board-MICU and available 24 h a day 7 days a week as part of a regional network (CORECAM), was associated with a decrease in the ischemia time, hospital stay and mortality of these patients in our environment.
