RESUMEN

In an era dominated by Internet of Things (IoT) devices, software-as-a-service (SaaS) platforms, and rapid advances in cloud and edge computing, the demand for efficient and lightweight models suitable for resource-constrained devices such as data processing units (DPUs) has surged. Traditional deep learning models, such as convolutional neural networks (CNNs), pose significant computational and memory challenges, limiting their use in resource-constrained environments. Echo State Networks (ESNs), based on reservoir computing principles, offer a promising alternative with reduced computational complexity and shorter training times. This study explores the applicability of ESN-based architectures in image classification and weather forecasting tasks, using benchmarks such as the MNIST, FashionMnist, and CloudCast datasets. Through comprehensive evaluations, the Multi-Reservoir ESN (MRESN) architecture emerges as a standout performer, demonstrating its potential for deployment on DPUs or home stations. In exploiting the dynamic adaptability of MRESN to changing input signals, such as weather forecasts, continuous on-device training becomes feasible, eliminating the need for static pre-trained models. Our results highlight the importance of lightweight models such as MRESN in cloud and edge computing applications where efficiency and sustainability are paramount. This study contributes to the advancement of efficient computing practices by providing novel insights into the performance and versatility of MRESN architectures. By facilitating the adoption of lightweight models in resource-constrained environments, our research provides a viable alternative for improved efficiency and scalability in modern computing paradigms.

RESUMEN

BACKGROUND: Several studies have described a potential anti-tumour effect of cannabinoids (CNB). CNB receptor 2 (CB2) is mostly present in hematopoietic stem cells (HSC). The present study evaluates the anti-leukaemic effect of CNB. METHODS: Cell lines and primary cells from acute myeloid leukaemia (AML) patients were used and the effect of the CNB derivative WIN-55 was evaluated in vitro, ex vivo and in vivo. RESULTS: We demonstrate a potent antileukemic effect of WIN-55 which is abolished with CB antagonists. WIN-treated mice, xenografted with AML cells, had better survival as compared to vehicle or cytarabine. DNA damage-related genes were affected upon exposure to WIN. Co-incubation with the PARP inhibitor Olaparib prevented WIN-induced cell death, suggesting PARP-mediated apoptosis which was further confirmed with the translocation of AIF to the nucleus observed in WIN-treated cells. Nicotinamide prevented WIN-related apoptosis, indicating NAD+ depletion. Finally, WIN altered glycolytic enzymes levels as well as the activity of G6PDH. These effects are reversed through PARP1 inhibition. CONCLUSIONS: WIN-55 exerts an antileukemic effect through Parthanatos, leading to translocation of AIF to the nucleus and depletion of NAD+, which are reversed through PARP1 inhibition. It also induces metabolic disruptions. These effects are not observed in normal HSC.

RESUMEN

INTRODUCTION: The relationship between the entorhinal cortex (EC) and the hippocampus has been studied by different authors, who have highlighted the importance of grid cells, place cells, and the trisynaptic circuit in the processes that they regulate: the persistence of spatial, explicit, and recent memory and their possible impairment with ageing. OBJECTIVE: We aimed to determine whether older age causes changes in the size and number of grid cells contained in layer III of the EC and in the granular layer of the dentate gyrus (DG) of the hippocampus. METHODS: We conducted post-mortem studies of the brains of 6 individuals aged 56-87 years. The brain sections containing the DG and the adjacent EC were stained according to the Klüver-Barrera method, then the ImageJ software was used to measure the individual neuronal area, the total neuronal area, and the number of neurons contained in rectangular areas in layer III of the EC and layer II of the DG. Statistical analysis was subsequently performed. RESULTS: We observed an age-related reduction in the cell population of the external pyramidal layer of the EC, and in the number of neurons in the granular layer of the DG. CONCLUSION: Our results indicate that ageing causes a decrease in the size and density of grid cells of the EC and place cells of the DG.

RESUMEN

Idiopathic Parkinson's disease (PD) is the second most common neurodegenerative disorder worldwide. It affects the nervous system, causing motor and non-motor symptomatology. However, its clinical diagnosis remains dependent on the expertise of clinicians, as perceptual clinical scales are often used. Gait stability is one of the most relevant motor signs in PD. Nonetheless, it is usually not reported or quantified, possibly due to its unclear meaning and the high variability of metrics used in the literature. This work aims to identify a reliable and objective indicator that clinicians can use to assess patients in realistic contexts. We focused on the Largest Lyapunov Exponent (LLE), being the most common metric used in previous research works to quantify gait stability. The short and long-term LLEs were calculated in a group of 34 healthy and 42 participants diagnosed with PD. The long-term LLE extracted from the chest, right arm and right foot sensors showed statistical differences between subjects with PD and healthy control (HC) subjects, showing that the HC subjects are more stable than PD patients, whereas the short-term LLE showed the opposite results. Further investigation is required to clarify the reliability of this metric to detect and rate gait stability in people affected with PD.Clinical Relevance- This study is the first step towards the identification of an objective methodology to assess gait stability in clinical settings. Achieving this goal will contribute to improve the understanding and support the diagnosis of gait disorders that cause gait stability problems.

RESUMEN

To analyse mortality associated to emergency admissions on weekends, differentiating whether the patients were admitted to the Internal Medicine department or to the hospital as a whole. Retrospective follow-up study of patients discharged between 2015 and 2019 in: (a) the Internal Medicine department (n = 7656) and (b) the hospital as a whole (n = 83,146). Logistic regression models were fitted to analyse the risk of death, adjusting for age, sex, severity, Charlson index, sepsis, pneumonia, heart failure and day of admission. Cox models were also adjusted for the time from admission until normal inpatient care. There was a significant increase in mortality for patients admitted in weekends with short stays in Internal Medicine (48, 72 and 96 h: OR = 2.50, 1.89 and 1.62, respectively), and hospital-wide (OR = 2.02, 1.41 and 1.13, respectively). The highest risk in weekends occurred on Fridays (stays ≤ 48 h: OR = 3.92 [95% CI 2.06-7.48]), being no significative on Sundays. The risk increased with the time elapsed from admission until the inpatient department took over care (OR = 5.51 [95% CI 1.42-21.40] when this time reached 4 days). In Cox models patients reached HR = 2.74 (1.00-7.54) when the delay was 4 days. Whether it was Internal Medicine or hospital-wide patients, the risk of death associated with emergency admission in WE increased with the time between admission and transfer of care to the inpatient department; consequently, Friday was the day with the highest risk while Sunday lacked a weekend effect. Healthcare systems should correct this serious problem.

RESUMEN

PURPOSE: Information and Communication Technologies have transformed our lives in different social areas, facilitating interpersonal relationships thanks to technological tools. In the specific case of people with disabilities, Assistive Technologies (ATs) break down barriers and increase opportunities to become active members of society with equal opportunities. MATERIALS AND METHODS: This paper presents a systematic mapping study that analyzes the current state-of-the-art of ATs proposed in the literature to support the empowering of people with disability. Specifically, this paper focuses on (1) describing a global vision of the scientific literature published in the last 20 years about ATs in the computer science field and (2) identifying research needs, gaps, and trends. RESULTS: For this purpose, an in-depth analysis of 389 primary studies is presented. The information obtained from the mapping process is also constrained. Concretely, 35 ATs versus 22 disabilities are compared, obtaining striking peaks for some disabilities described in the discussion. CONCLUSIONS: Finally, the findings show that several areas have been covered only lightly, revealing interesting future directions and challenges for junior researchers.


• ATs have the potential to break down barriers for people with disabilities, enabling them to participate more fully in society. This implies a need for rehabilitation programs to incorporate ATs into their strategies to enhance social inclusion.• Given the transformative role of ICT, rehabilitation programs should focus on helping people with disabilities develop the necessary technological skills to utilize ATs effectively.• This work highlights the diversity of ATs and disabilities, suggesting a need for personalized rehabilitation plans that match specific ATs to individual disabilities.• Rehabilitation professionals should be trained to assess and recommend appropriate ATs for each case. Rehabilitation programs should consider incorporating cutting-edge ATs and staying involved in research to contribute to future developments to cover gaps and challenges identified.

RESUMEN

OBJECTIVE: We aim to evaluate the adherence rate to an Antimicrobial Stewardship Program (ASP) in an Intensive Care Unit (ICU), and to assess its effect on the use of antibiotics, quality indicators and clinical outcomes. METHODS: Retrospective description of the interventions proposed by the ASP. We compared antimicrobial use, quality and safety indicators in an ASP versus a non-ASP period. The study was performed in a polyvalent ICU of a medium-size University Hospital (600 beds). We studied patients admitted to the ICU for any cause during the ASP period, provided that a microbiological sample aiming to diagnose a potential infection has been drawn, or antibiotics have been started. We elaborated and registered of non-mandatory recommendations to improve antimicrobial prescription (audit and feedback structure) and its registry during the ASP period (15 months, October 2018-December 2019). We compared indicators in a period with ASP (April-June 2019) and without ASP (April-June 2018). RESULTS: We issued 241 recommendations on 117 patients, 67% of them classified as de-escalation type. The rate of adherence to the recommendations was high (96.3%). In the ASP period, the mean number of antibiotics per patient (3.3±4.1 vs 2.4±1.7, p=0.04) and the days of treatment (155 DOT/100 PD vs 94 DOT/100 PD, p <0.01) were reduced. The implementation of the ASP did not compromise patient safety or produce changes in clinical outcomes. CONCLUSIONS: The implementation of an ASP is widely accepted in the ICU, reducing the consumption of antimicrobials, without compromising patient safety.

RESUMEN

OBJECTIVES: To analyze clinical features associated to mortality in oncological patients with unplanned admission to the Intensive Care Unit (ICU), and to determine whether such risk factors differ between patients with solid tumors and those with hematological malignancies. DESIGN: An observational study was carried out. SETTING: A total of 123 Intensive Care Units across Spain. PATIENTS: All cancer patients with unscheduled admission due to acute illness related to the background oncological disease. INTERVENTIONS: None. MAIN VARIABLES: Demographic parameters, severity scores and clinical condition were assessed, and mortality was analyzed. Multivariate binary logistic regression analysis was performed. RESULTS: A total of 482 patients were included: solid cancer (n=311) and hematological malignancy (n=171). Multivariate regression analysis showed the factors independently associated to ICU mortality to be the APACHE II score (OR 1.102; 95% CI 1.064-1.143), medical admission (OR 3.587; 95% CI 1.327-9.701), lung cancer (OR 2.98; 95% CI 1.48-5.99) and mechanical ventilation after the first 24h of ICU stay (OR 2.27; 95% CI 1.09-4.73), whereas no need for mechanical ventilation was identified as a protective factor (OR 0.15; 95% CI 0.09-0.28). In solid cancer patients, the APACHE II score, medical admission, antibiotics in the previous 48h and lung cancer were identified as independent mortality indicators, while no need for mechanical ventilation was identified as a protective factor. In the multivariate analysis, the APACHE II score and mechanical ventilation after 24h of ICU stay were independently associated to mortality in hematological cancer patients, while no need for mechanical ventilation was identified as a protective factor. Neutropenia was not identified as an independent mortality predictor in either the total cohort or in the two subgroups. CONCLUSIONS: The risk factors associated to mortality did not differ significantly between patients with solid cancers and those with hematological malignancies. Delayed intubation in patients requiring mechanical ventilation might be associated to ICU mortality.

RESUMEN

BACKGROUND AND OBJECTIVE: Knee arthroplasty is a major surgery with potential significant blood loss. Assess the efficacy and safety of topical administration of 3g of tranexamic acid (TXA) in terms of reducing blood loss in knee arthroplasty. MATERIAL AND METHOD: A randomized, phase III, double-blind, placebo-controlled clinical trial has been conducted. We included 150 patients in 2 parallel treatment groups (75 per arm). The solution was administered topically intra-articular after cementation and prior to capsular closure. Analytical determinations were made before and after surgery to quantify blood loss. RESULTS: Total blood loss for the placebo group was 831.5ml and 662.3ml for the TXA group. The difference between the 2 groups was 169.2ml; which means a save of 20.4%; this difference being statistically significant (p<.001). There were no differences in terms of the onset of ambulation, days of admission or visual analogue scale at one month of surgery. Ten patients were rejected for presurgical urinary tract infection, metal allergy, selection failure, patellar weakening, prosthetic instability, intrasurgical tibial fracture, change of indication to unicompartimental prosthesis and a loss of follow-up. There was only one complication unrelated to the investigational drug (bladder balloon). CONCLUSION: The administration of TXA topically after cementation of the prosthetic components in total knee arthroplasty in a single dose has demonstrated being safe and effective.

RESUMEN

BACKGROUND: While suicide rates in high- and middle-income countries appeared stable in the early stages of the pandemic, we know little about within-country variations. We sought to investigate the impact of COVID-19 on suicide in Mexico's 32 states and to identify factors that may have contributed to observed variations between states. METHODS: Interrupted time-series analysis to model the trend in monthly suicides before COVID-19 (from Jan 1, 2010, to March 31, 2020), comparing the expected number of suicides derived from the model with the observed number for the remainder of the year (April 1 to December 31, 2020) for each of Mexico's 32 states. Next, we modeled state-level trends using linear regression to study likely contributing factors at ecological level. RESULTS: Suicide increased slightly across Mexico during the first nine months of the pandemic (RR 1.03; 95%CI 1.01-1.05). Suicides remained stable in 19 states, increase in seven states (RR range: 1.12-2.04) and a decrease in six states (RR range: 0.46-0.88). Suicide RR at the state level was positively associated with population density in 2020 and state level suicide death rate in 2019. CONCLUSIONS: The COVID-19 pandemic had a differential effect on suicide death within the 32 states of Mexico. Higher population density and higher suicide rates in 2019 were associated with increased suicide. As the country struggles to cope with the ongoing pandemic, efforts to improve access to primary care and mental health care services (including suicide crisis intervention services) in these settings should be given priority.

RESUMEN

P-type and n-type metal oxide semiconductors are widely used in the manufacture of gas sensing materials, due to their excellent electronic, electrical and electrocatalytic properties. Hematite (α-Fe2O3) compound has been reported as a promising material for sensing broad types of gases, due to its affordability, good stability and semiconducting properties. In the present work, the efficient and easy-to-implement sol-gel method has been used to synthesizeα-Fe2O3nanoparticles (NPs). The TGA-DSC characterizations of the precursor gel provided information about the phase transformation temperature and the mass percentage of the hematite NPs. X-ray diffraction, transmission electron microscopy and x-ray photoelectron spectroscopy data analyses indicated the formation of two iron oxide phases (hematite and magnetite) when the NPs are subjected to thermal treatment at 400 °C. Meanwhile, only the hematite phase was determined for thermal annealing above 500 °C up to 800 °C. Besides, the crystallite size shows an increasing trend with the thermal annealing and no defined morphology. A clear reduction of surface defects, associated with oxygen vacancies was also evidenced when the annealing temperature was increased, resulting in changes on the electrical properties of hematite NPs. Resistive gas-sensing tests were carried out using hematite NPs + glycerin paste, to detect quaternary ammonium compounds. Room-temperature high sensitivity values (Sr âˆ¼ 4) have been obtained during the detection of ∼1 mM quaternary ammonium compounds vapor. The dependence of the sensitivity on the particle size, the mass ratio of NPs with respect to the organic ligand, changes in the dielectric properties, and the electrical conduction mechanism of gas sensing was discussed.

RESUMEN

Olmesartan is a potent angiotensin II receptor antagonist commonly used in the treatment of high blood pressure. During the last decade, several cases of sprue-like enteropathy have been described associated with the use of this drug - with severe clinical involvement that requires hospitalization - but fortunately with complete remission after its discontinuation. We present the case of a multi-pathological 82-year-old woman with a chronic diarrhoeal syndrome that resulted in a weight loss of 20kg over the last three months. She was prescribed dual therapy for her hypertension: olmesartan 40mg, torasemide 10mg, and lercanidipine 10mg/day. Based on the findings of the patient presented, we conducted a literature search of all the cases published in Spanish indexed journals (PubMed) and compared them, attempting to establish a suspicion profile that would result in the suspension of olmesartan and accelerate the complementary tests necessary to rule out other diagnoses.

RESUMEN

INTRODUCTION: the orthopedic shoe is usually prescribed during postoperative care after hallux valgus surgery to protect the osteotomy and provide functional comfort to the patient. In this regard, the superiority of rigid sole shoe (RSS) compared to the reverse camber shoe (RCS) remains controversial. The aim of this study is to compare the clinical, functional and radiological outcomes from using the rigid sole shoe (RSS) vs. the reverse camber shoe (RCS) after hallux valgus surgery. MATERIAL AND METHODS: fifty-seven hallux valgus surgery patients were included and analyzed retrospectively. The 1st group included 28 patients using the RSS and the 2nd group included 29 patients using the RCS. The orthopedic shoe was used for six weeks postoperatively. Clinical data (lumbar and lower limb pain, need of crutches and problems with going up and down stairs), radiological data (IMA, HVA) and postoperative complications (displacement of osteotomy, metatarsal fracture or non-union) were collected. RESULTS: the RSS showed less difficulty going up and down stairs (OR 3.8 (CI 95% 1.2-12.8), p 0.02), only going upstairs (OR 3.2 (CI 95% 1.1-10), p 0.03), as well as a decreased need for crutches (OR 1.7 (CI 95% 1.04-2.6), p < 0.03). Lumbar spine or lower limb pain did not show any statistical differences. No statistical differences in the epidemiological and radiological data were found between the groups. CONCLUSIONS: the RSS seems to provide more comfort to the patients without worsening the radiological results.


INTRODUCCIÓN: el calzado ortopédico suele prescribirse en el postoperatorio de cirugía de hallux valgus para proteger la osteotomía y mantener la funcionalidad al paciente. En este sentido, la superioridad del zapato de suela rígida en comparación con el zapato de suela invertida sigue siendo controvertido. El objetivo de este estudio es comparar los resultados clínicos, funcionales y radiológicos entre el uso del zapato de suela rígida (ZSR) y el zapato de suela invertida (ZSI) después de la cirugía de hallux valgus. MATERIAL Y MÉTODOS: un total de 57 pacientes intervenidos de hallux valgus fueron incluidos y analizados retrospectivamente. En un grupo se incluyeron 28 pacientes que usaron el ZSR, mientras que el segundo grupo incluyó a 29 pacientes que usaron el ZSI. El zapato ortopédico se usó durante seis semanas tras la cirugía. Se recogieron datos clínicos (dolor lumbar y articular de las extremidades inferiores, necesidad de muletas y problemas para subir y bajar escaleras), datos radiológicos (AIM, AHV), así como complicaciones postoperatorias (desplazamiento de osteotomía, fractura del primer metatarsiano o seudoartrosis). RESULTADOS: el zapato de suela rígida mostró menor dificultad para subir y bajar escaleras (OR 3.8 (IC 95% 1.2-12.8), p 0.02), sólo para subir (OR 3.2 (IC 95% 1.1-10), p 0.03), así como una disminución de la necesidad de muletas (OR 1.7 (IC 95% 1.04-2.6), p < 0.03). El dolor de columna lumbar o articular de extremidades inferiores no mostró diferencias estadísticas. No se encontraron diferencias estadísticas en los datos epidemiológicos y radiológicos entre los grupos. CONCLUSIONES: el zapato de suela parece aportar más comodidad a los pacientes sin aumentar las complicaciones radiológicas.

RESUMEN

BACKGROUND: The incidence of non-AIDS defining cancer (NADC) is higher in people living with HIV (PLWH) than in the general population, and it is already one of the leading causes of death in the HIV-infected population. It is estimated that the situation will be aggravated by the progressive aging of PLWH. Early diagnosis through intensive cancer screening may improve the ability for therapeutic interventions and could be critical in reducing mortality, but it might also increase expenditure and harms associated with adverse events. The aim of this study is to evaluate an enhanced screening program for early diagnosis of cancer in PLWH compared to standard practice. The specific objectives are (1) to compare the frequency of cancer diagnosed at an early stage, (2) to analyze safety of the enhanced program: adverse events and unnecessary interventions, (3) to analyze the cost-utility of the program, and (4) to estimate the overall and site-specific incidence of NADC in PLWH. METHODS: We will conduct a multicenter, non-blinded, randomized, controlled trial, comparing two parallel arms: conventional vs enhanced screening. Data will be recorded in an electronic data collection notebook. Conventional intervention group will follow the standard of care screening in the participating centers, according to the European AIDS Clinical Society recommendations, and the enhanced intervention group will follow an expanded screening aimed to early detection of lung, liver, anal, cervical, breast, prostate, colorectal, and skin cancer. The trial will be conducted within the framework of the Spanish AIDS Research Network Cohort (CoRIS). DISCUSSION: The trial will evaluate the efficacy, safety, and efficiency of an enhanced screening program for the early diagnosis of cancer in HIV patients compared to standard of care practice. The information provided will be relevant since there are currently no studies on expanded cancer screening strategies in patients with HIV, and available data estimating cost effectiveness or cost-utility of such as programs are scarce. An enhanced program for NADC screening in patients with HIV could lead to early diagnosis and improve the prognosis of these patients, with an acceptable rate of unnecessary interventions, but it is critical to demonstrate that the benefits clearly outweigh the harms, before the strategy could be implemented. TRIAL REGISTRATION: ClinicalTrials.gov NCT04735445. Registered on 25 June 2019.
