Background: Laparoscopic surgery has advanced significantly; however, effective communication within the surgical team remains challenging, particularly in training scenarios where misinterpretation of instructions can lead to errors. Virtual pointers, indicating the instructor's gaze through eye-tracking devices and overlaying it onto the screen using augmented reality (AR), can enhance understanding and reduce errors., Methods: In a study involving 10 participants divided into experts and novices in laparoscopic surgery, various pointers (differing in shape, size and colour) were analysed in an AR environment using the HoloLens2 device. The aim was to assess the acceptance of these pointers by both groups, understand how their characteristics affect perception, and evaluate the AR device's usefulness., Results: Initial results showed an 80% acceptance rate. After analysing the pointers, this decreased to 60%, as some experts changed their opinion from positive to neutral. The study revealed that the characteristics of the pointers significantly affect their perception, with large, thick-rimmed pointers being preferred. Orange was the best-performing colour. The device used also influenced perception, as experts who changed their perception criticised certain aspects of the head-mounted display., Conclusions: The study highlights the potential of virtual pointers to improve communication in laparoscopic training, particularly when their size, shape, and colour are optimised. Further research with a larger sample size is needed to confirm these results and explore the HoloLens2's influence on users' perceptions. These insights could guide the development of more effective training tools for minimally invasive surgery., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: Javier Jiménez-Ruescas, Fco.

Background: The differences in clinical bioethics between the Mediterranean and Latin American cultures have not been analyzed. The objective of the study is to compare the ethical conflicts that internists in Spain, Mexico and Argentina have., Methods: Cross-sectional observational study through a survey directed at internists from Spain, Argentina and Mexico. The survey was administered to affiliated members of the National Societies of Internal Medicine across three countries via an online platform., Results: 762 internists participated, 261 from Spain, 154 from Argentina and 347 from Mexico. The main ethical conflicts that internists in Spain, Argentina and Mexico have are related (in order) to the end of life, to the clinical relationship and to the patient's autonomy. Withholding and withdrawing life-sustaining treatment is the most frequent conflict in Spain and Argentina and the second in Mexico., Conclusions: Internists from Spain and Argentina identify very similar ethical conflicts. Furthermore, they consider them more frequent and difficult than in Mexico. In Argentina they are less satisfied with the way they are resolved. To explain these differences, socio-cultural factors are postulated, among others: paternalism, individualism, masculinity, organization of the health system, formal training in bioethics and assessment of death., (© 2024.

Aim: To investigate if tachypneic response to hypoxia is decreased in older patients., Methods: We included all patients ≥65 years of age attending 52 Spanish emergency departments (EDs) for whom peripheral arterial oxygen saturation (SatO 2 ) measured by pulsioxymetry and respiratory rate (RR) were registered at ED arrival. We assessed the relationship between SatO2 and RR in different models, and with the best-fitting model, we independently analyzed this relationship in four subgroups according to patient age (65-69, 70-79, 80-89, and ≥90 years). Five sensitivity analyses using different subsets of patients were carried out to check for the consistency of the results., Results: We included 7126 patients, with medians for SatO 2 and RR of 97% (interquartile range [IQR]: 94-98) and 15 bpm (IQR: 15-16), respectively. We found significant associations (P < 0.001) between SatO 2 and RR in every model tested (P < 0.001 for all), with the quadratic model obtaining the best fit (R 2 : 0.098) over those obtained with linear (R 2 : 0.096) and logarithmic (R 2 : 0.092) models. The same was observed in sensitivity analyses, with R 2 for quadratic models ranging from 0.069 in patients with low comorbidity and 0.102 in patients breathing room air. The mean RR for 100% SatO 2 was 15 bpm and increased as SatO 2 decreased, although with a progressive slowing of the slope, with a mean RR of 27 at 50% SatO 2 . We detected a decreased RR response to increasing hypoxemia according to age and, while the RR curve was higher and with a progressively steepening slope in the 972 patients aged 65-69 (mean RR of 42 bpm with 50% SatO 2 ), a progressive slowing of slope was observed in the 2693 patients aged 70-79 (mean RR of 28 with 50% SatO2), the 2582 aged 80-89 (mean RR of 25) and the 879 aged ≥90 (mean RR of 23). Sensitivity analyses provided very similar results., Conclusion: Tachypneic response to hypoxemia in older patients decreases as age advances, regardless of the reason leading to hypoxemia.

Introduction and Objectives: This article presents the 2023 activity report of the Interventional Cardiology Association of the Spanish Society of Cardiology (ACI-SEC)., Methods: All interventional cardiology laboratories in Spain were invited to participate in an online survey. Data analysis was carried out by an external company and subsequently reviewed and presented by the members of the ACI-SEC board., Results: A total of 119 hospitals participated. The number of diagnostic studies decreased by 1.8%, while the number of percutaneous coronary interventions (PCI) showed a slight increase. There was a reduction in the number of stents used and an increase in the use of drug-coated balloons. The use of intracoronary diagnostic techniques remained stable. For the first time, data on PCI guided by intracoronary imaging was reported, showing a 10% usage rate in Spain. Techniques for plaque modification continued to grow. Primary PCI increased, becoming the predominant treatment for myocardial infarction (97%). Noncoronary structural procedures continued their upward trend. Notably, the number of left atrial appendage closures, patent foramen ovale closures, and tricuspid valve interventions grew in 2023. There was also a significant increase in interventions for acute pulmonary embolism., Conclusions: The 2023 Spanish cardiac catheterization and coronary intervention registry indicates a stabilization in coronary interventions, together with an increase in complexity. There was consistent growth in procedures for both valvular and nonvalvular structural heart diseases., (Copyright © 2024 Sociedad Española de Cardiología. Published by Elsevier España, S.L.U.

Introduction: Optical Coherence Tomography Angiography Ratio Analysis (OCTARA) is capable of visualizing inner and outer retinal vascular plexuses, choriocapillaris, and larger choroidal vasculature in vivo without contrast injection. The aim of this study was to assess the intrasession repeatability of automated vessel density measurements using Triton Swept-Source Optical Coherence Tomography Angiography (OCTA) innovative algorithm OCTARA in retinal and choroidal vasculature., Methods: To study population between 65-90 years old with no eye diseases. For each subject measurements were performed four times. The intraclass correlation coefficient and the coefficient of variation were calculated to analyze repeatability of the OCTARA automatically generated vessel density measurements., Results: A total of 35 eyes were included in the study. The intraclass correlation coefficient of the global vessel density in the superficial capillary plexus and the deep capillary plexus were 0.963 and 0.975, respectively, and the coefficient of variation were 5.4% and 4.4%, respectively. The intraclass correlation coefficient of the rest of the global measurements was indicative of good reliability with the exception of the deep choroid layer with an intraclass correlation coefficient of 0.6 indicative of moderate reliability., Conclusions: Our results proved excellent repeatability of automated vessel density measurements in the superficial and deep capillary plexus layers in our cohort using a OCTARA algorithm indicating that it may be a reliable diagnostic tool. It also showed good reliability in choriocapillary and mid choroid layer. These findings may be of value in assessing the significance of differences in capillary density measurements over time and across different settings., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Objective: To analyze the prognostic accuracy of the scores NEWS, qSOFA, GYM used in hospital emergency department (ED) in the assessment of elderly patients who consult for an infectious disease., Methods: Data from the EDEN (Emergency Department and Elderly Need) cohort were used. This retrospective cohort included all patients aged ≥65 years seen in 52 Spanish EDs during two weeks (from 1-4-2019 to 7-4-2019 and 30/3/2020 to 5/4/2020) with an infectious disease diagnosis in the emergency department. Demographic variables, demographic variables, comorbidities, Charlson and Barthel index and needed scores parameters were recorded. The predictive capacity for 30-day mortality of each scale was estimated by calculating the area under the receiver operating characteristic (ROC) curve, and sensitivity and specificity were calculated for different cut-off points. The primary outcome variable was 30-day mortality., Results: 6054 patients were analyzed. Median age was 80 years (IQR 73-87) and 45.3% women. 993 (16,4%) patients died. NEWS score had better AUC than qSOFA (0.765, 95CI: 0.725-0.806, versus 0.700, 95%CI: 0.653-0.746; P < .001) and GYM (0.716, 95%CI: 0.675-0.758; P = .024), and there was no difference between qSOFA and GYM (P = .345). The highest sensitivity scores for 30-day mortality were GYM ≥ 1 point (85.4%) while the qSOFA score ≥2 points showed high specificity. In the case of the NEWS scale, the cut-off point ≥4 showed high sensitivity, while the cut-off point NEWS ≥ 8 showed high specificity., Conclusion: NEWS score showed the highest predictive capacity for 30-day mortality. GYM score ≥1 showed a great sensitivity, while qSOFA ≥2 scores provide the highest specificity but lower sensitivity., (Copyright © 2024. Published by Elsevier España, S.L.U.)

Introduction: Diagnosing moderate haemophilia A (MHA) solely based on deficient FVIII protein levels limits its optimal management and delays the initiation of prophylaxis. Updating protocols and incorporating new variables into its diagnosis could prevent underestimating disease severity, avoiding early arthropathies and impairing patients' quality of life., Aim: To propose recommendations to improve the comprehensive management of people with MHA., Methods: Recommendations from a Spanish panel of eight experts from public comprehensive care centres (CCCs) for people with haemophilia and over 140 people with MHA in follow-up. In a previous analysis, the panel identified the unmet needs of people with MHA and the necessity to develop new specific recommendations for their management., Results: The panel proposed recommendations in four areas: diagnosis, treatment, follow-up and referrals. They detailed the necessary steps and procedures for the diagnosis, adding other variables to the FVIII levels like bleeding phenotype, genetic profile and joint status to specify the severity and risk classification of people with MHA. Experts proposed an algorithm with unique independent criteria to facilitate the decision to initiate prophylaxis, where the recommended FVIII levels and variables coexist for treatment decision-making. Follow-up proposals addressed periodicity, recommended tests and required visits to CCCs. For referrals, experts proposed criteria and situations considered urgent for a transfer to a CCC for haemophilia patients., Conclusion: The proposals agreed upon by this expert panel can contribute to update and optimize the management of people with MHA, delaying joint deterioration, pain and disabilities, and improving their quality of life., (© 2024 John Wiley & Sons Ltd.)

Introduction: Nitrogen (N) and iron (Fe) are involved in several biochemical processes in living organisms, and their limited bioavailability is a strong constraint for plant growth and yield. This work investigated the interplay between Fe and N nutritional pathways in tomato plants kept under N and Fe deficiency and then resupplied with Fe and N (as nitrate, ammonium, or urea) through a physiological, metabolomics and gene expression study., Results: After 24 hours of Fe resupply, the Fe concentration in Fe-deficient roots was dependent on the applied N form (following the pattern: nitrate > urea > ammonium > Fe-deficient control), and whereas in leaves of urea treated plants the Fe concentration was lower in comparison to the other N forms. Untargeted metabolomics pointed out distinctive modulations of plant metabolism in a treatment-dependent manner. Overall, N-containing metabolites were affected by the treatments in both leaves and roots, while N form significantly shaped the phytohormone profile. Moreover, the simultaneous application of Fe with N to Fe-deficient plants elicited secondary metabolites' accumulation, such as phenylpropanoids, depending on the applied N form (mainly by urea, followed by nitrate and ammonium). After 4 hours of treatment, ammonium- and urea-treated roots showed a reduction of enzymatic activity of Fe(III)-chelate reductase (FCR), compared to nitrate or N-depleted plants (maintained in Fe deficiency, where FCR was maintained at high levels). The response of nitrate-treated plants leads to the improvement of Fe concentration in tomato roots and the increase of Fe(II) transporter (IRT1) gene expression in tomato roots., Conclusions: Our results strengthen and improve the understanding about the interaction between N and Fe nutritional pathways, thinning the current knowledge gap., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

Objectives: The aim of the present study was to evaluate the impact of chronic treatment with angiotensin-converting enzyme inhibitors (ACEI) or angiotensin receptor blockers (ARB) on short-term clinical outcomes after an episode of AHF., Methods: A secondary analysis of patients included in the EAHFE (Epidemiology of Acute Heart Failure in Emergency Departments) cohort, which includes patients diagnosed with AHF in 45 Spanish Emergency Departments (EDs). The primary outcome was all-cause in-hospital mortality. The secondary outcomes were all-cause death within 7 days, need for hospital admission and prolonged hospitalisation defined as a stay longer than or equal to 7 days. Multiple regression and propensity-matching was used for multivariate adjustment., Results: Of the 17,920 patients, 10,041 (56 %) were receiving chronic treatment with ACEI/ARB. The mean age was 80.4 years and 55.7 % were women. Adjusted odds ratios (aOR) were 0.76 (95 % CI 0.71-0.82) for in-hospital mortality witch multiple regression and 0.74 (95 %CI 0.63-0.88) with propensity-matching. aOR were 0.72; (95 %CI 0.65-0.79) and 0.70 (95 %CI 0.57-0.87) for mortality at the 7-day follow-up, respectively. The sensitivity analysis ACEI/ARB were associated with few all-cause deaths in patients with elevated natriuretic peptides in the EDs (aOR 0.74; 95 % CI 0.68-0.80), patients requiring hospital admission (aOR 0.78; 95 % CI 0.73-0.84) and patients with a history of HF (aOR 0.72; 95 % CI 0.66-0.78)., Conclusions: Chronic use of ACEI/ARB was associated with better short-term outcomes in terms of all-cause in-hospital mortality in patients with AHF who attend an EDs., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

Species life history and anthropogenic influence are important drivers of population performance and viability in human-dominated ecosystems. How these factors affect habitat selection and occupancy in long-lived species is an important topic for their conservation. Long-term datasets are needed for establishing the underlying drivers of this process. In this 22 year-long study, we conducted annual surveys of Bonelli's eagle in the east of the Iberian Peninsula. During this period, 42.8% of the known territories remained unoccupied. Territories with a higher likelihood of raising two chicks over time were stable, evidenced by a lower coefficient of variation in productivity, and were more likely to remain occupied. Moreover, territories with lower habitat diversity, dominated by coniferous forest or agricultural fields, and those located further away from the coast and at higher altitudes showed lower rates of occupancy (i.e., unoccupied >3 consecutive years). To validate these associations, we monitored space use of 22 individuals equipped with Global Positioning System/Global System for Mobile (GPS/GSM) transmitters, which confirmed that eagles selected for open habitats (mainly scrublands and transitional woodland-scrubs) intermixed with forest areas within their home ranges. In contrast, individuals avoided areas dominated by agricultural, urban, and continuous forests for breeding in line with the observations for unoccupied territories. Our results highlight the important interplay between natural and anthropogenic factors, which also have important implications for other raptor species. Preservation of the most productive territories and the re-occupancy of unoccupied territories along with reducing threats in the preferred habitats are fundamental actions that should be taken immediately to sustain viable populations. Potential management actions include enhancing natural prey density through habitat restoration and conservation, mitigating threats and reducing mortality risks due to power lines, fences, poisoning, and maintaining habitat heterogeneity important to eagles' hunting activities., (© 2024 The Author(s).

The genetic basis of severe COVID-19 has been thoroughly studied, and many genetic risk factors shared between populations have been identified. However, reduced sample sizes from non-European groups have limited the discovery of population-specific common risk loci. In this second study nested in the SCOURGE consortium, we conducted a genome-wide association study (GWAS) for COVID-19 hospitalization in admixed Americans, comprising a total of 4702 hospitalized cases recruited by SCOURGE and seven other participating studies in the COVID-19 Host Genetic Initiative. We identified four genome-wide significant associations, two of which constitute novel loci and were first discovered in Latin American populations ( BAZ2B and DDIAS ). A trans-ethnic meta-analysis revealed another novel cross-population risk locus in CREBBP . Finally, we assessed the performance of a cross-ancestry polygenic risk score in the SCOURGE admixed American cohort. This study constitutes the largest GWAS for COVID-19 hospitalization in admixed Latin Americans conducted to date. This allowed to reveal novel risk loci and emphasize the need of considering the diversity of populations in genomic research., Competing Interests: SD, RC, AL, JL, Md, IQ, RG, VN, MP, JT, JN, JA, CA, SA, VA, BA, NA, ÁA, EA, CA, MA, MA, RB, MB, MB, JB, MB, LB, MB, RB, MB, EC, CC, LC, JC, RC, MC, JC, MC, MD, AD, Vd, Ad, ED, RE, MF, MF, UF, AF, TF, MG, BG, JG, BÁ, FB, AG, JG, JG, MH, AH, MJ, ML, AB, RL, EM, CM, VM, OM, IM, MM, AM, JM, EM, PM, VC, SO, EO, MP, EP, NS, PP, PP, MP, TP, MP, GP, EP, GP, AP, SL, SR, MF, ER, FR, JR, FR, JR, PR, JS, JS, ET, AT, JT, AT, LT, MU, JV, ZY, RZ, Id, AR, PS, LR, EG, CA, EP, JR, AR, CF, PL, ÁC No competing interests declared, (© 2024, Diz-de Almeida, Cruz et al.)

Importance: Poststroke cognitive impairment is common, but the cognitive trajectory following a first stroke, relative to prestroke cognitive function, remains unclear., Objective: To map the trajectory of cognitive function before any stroke and after stroke in global cognition and in 4 cognitive domains, as well as to compare the cognitive trajectory prestroke in stroke survivors with the trajectory of individuals without incident stroke over follow-up., Design, Setting, and Participants: The study used harmonized and pooled data from 14 population-based cohort studies included in the Cohort Studies of Memory in an International Consortium collaboration. These studies were conducted from 1993 to 2019 across 11 countries among community-dwelling older adults without a history of stroke or dementia. For this study, linear mixed-effects models were used to estimate trajectories of cognitive function poststroke relative to a stroke-free cognitive trajectory. The full model adjusted for demographic and vascular risk factors. Data were analyzed from July 2022 to March 2024., Exposure: Incident stroke., Main Outcomes and Measures: The primary outcome was global cognition, defined as the standardized average of 4 cognitive domains (language, memory, processing speed, and executive function). Cognitive domain scores were formed by selecting the most commonly administered test within each domain and standardizing the scores., Results: The study included 20 860 participants (12 261 [58.8%] female) with a mean (SD) age of 72.9 (8.0) years and follow-up of 7.51 (4.2) years. Incident stroke was associated with a substantial acute decline in global cognition (-0.25 SD; 95% CI, -0.33 to -0.17 SD), the Mini-Mental State Examination, and all cognitive domains (ranging from -0.17 SD to -0.22 SD), as well as accelerated decline in global cognition (-0.038 SD per year; 95% CI, -0.057 to -0.019 SD per year) and all domains except memory (ranging from -0.020 to -0.055 SD per year), relative to a stroke-free cognitive trajectory. There was no significant difference in prestroke slope in stroke survivors compared with the rate of decline in individuals without stroke in all cognitive measures. The mean rate of decline without a previous stroke was -0.049 SD per year (95% CI, -0.051 to -0.047 SD) in global cognition., Conclusions and Relevance: In this cohort study using pooled data from 14 cohorts, incident stroke was associated with acute and accelerated long-term cognitive decline in older stroke survivors.

Plant long noncoding RNAs (lncRNAs) exhibit features such as tissue-specific expression, spatiotemporal regulation, and stress responsiveness. Although diverse studies support the regulatory role of lncRNAs in model plants, our knowledge about lncRNAs in crops is limited. We employ a custom pipeline on a dataset of over 1000 RNA-seq samples across nine representative species of the family Cucurbitaceae to predict 91 209 nonredundant lncRNAs. The lncRNAs were characterized according to three confidence levels and classified by their genomic context into intergenic, natural antisense, intronic, and sense-overlapping. Compared with protein-coding genes, lncRNAs were, on average, expressed at low levels and displayed significantly higher specificity when considering tissue, developmental stages, and stress responsiveness. The evolutionary analysis indicates higher positional conservation than sequence conservation, probably linked to the conserved modular motifs within syntenic lncRNAs. Moreover, a positive correlation between the expression of intergenic/natural antisense lncRNAs and their closest/parental gene was observed. For those intergenic, the correlation decreases with the distance to the neighboring gene, supporting that their potential cis-regulatory effect is within a short-range. Furthermore, the analysis of developmental studies showed that a conserved NAT-lncRNA family is differentially expressed in a coordinated way with their cognate sense protein-coding genes. These genes code for proteins associated with phloem development, thus providing insights about the potential involvement of some of the identified lncRNAs in a developmental process. We expect that this extensive inventory will constitute a valuable resource for further research lines focused on elucidating the regulatory mechanisms mediated by lncRNAs in cucurbits., (© 2024 The Author(s).

Aims: To investigate whether seasonal influenza and COVID-19 vaccinations influence the severity of decompensations and long-term outcomes of patients with acute heart failure (AHF)., Methods and Results: We included consecutive AHF patients attended at 40 Spanish emergency departments during November and December 2022. They were grouped according to whether they had received seasonal influenza and COVID-19 vaccination. The severity of heart failure (HF) decompensation was assessed with the MEESSI scale, need for hospitalization, intensive care unit (ICU) admission, and in-hospital mortality. Long-term outcomes were 90-day and 1-year all-cause mortality. Associations between vaccination, HF decompensation severity, and long-term outcomes were investigated. Subgroup analyses were executed for 16 patient characteristics and their relationship with vaccination and 1-year mortality. We analysed 4243 patients (median age 85 years; interquartile range 77-90; 57% female): 1841 (43%) had received influenza vaccination, 3139 (74%) COVID-19 vaccination, 1773 (41.8%) received both vaccines (full vaccination) and 1036 (24.4%) none. Previous episodes of AHF, chronic obstructive pulmonary disease and chronic treatment with diuretics were associated with vaccination (either influenza, COVID-19 and full vaccination). High or very-high risk decompensation occurred in 18.6%; hospitalization in 72.3%, ICU admission in 1.1%, and in-hospital mortality in 8.4%. Influenza vaccination was associated with lower hospitalization rates (adjusted odds ratio [OR] 0.746, 95% confidence interval [CI] 0.636-0.876) and in-hospital mortality (OR 0.761, 95% CI 0.583-0.992), while COVID-19 vaccination was associated with increased hospitalizations (OR 1.215, 95% CI 1.016-1.454). Overall, 90-day and 1-year mortality were 20.3% and 34.4%. Both were decreased in influenza-vaccinated patients (adjusted hazard ratio [HR] 0.831, 95% CI 0.709-0.973; and HR 0.885, 95% CI 0.785-0.999, respectively) but only at 90 days in COVID-19 vaccinated patients (HR 0.829, 95% CI 0.702-0.980). Full vaccination achieved even greater reductions in in-hospital, 90-day, and 1-year mortality (HR 0.638, 95% CI 0.479-0.851; HR 0.702, 95% CI 0.592-0.833; and HR 0.815, 95% CI 0.713-0.931, respectively). Subgroup analysis based on patient-related characteristics demonstrated the consistence of vaccination with long-term survival., Conclusion: In HF patients, seasonal influenza vaccination appears to be associated with less severe decompensation and lower 1-year mortality, while no firm conclusions can be drawn from the results of the present study regarding the benefits of COVID-19 vaccination. Full vaccination is associated with the greatest reduction in short- and long-term mortality., (© 2024 European Society of Cardiology.)

Amyotrophic lateral sclerosis (ALS) is an adult-onset motor neuron disease with a mean survival time of three years. The 97% of the cases have TDP-43 nuclear depletion and cytoplasmic aggregation in motor neurons. TDP-43 prevents non-conserved cryptic exon splicing in certain genes, maintaining transcript stability, including ATG4B, which is crucial for autophagosome maturation and Microtubule-associated proteins 1A/1B light chain 3B (LC3B) homeostasis. In ALS mice (G93A), Atg4b depletion worsens survival rates and autophagy function. For the first time, we observed an elevation of LC3ylation in the CNS of both ALS patients and atg4b -/- mouse spinal cords. Furthermore, LC3ylation modulates the distribution of ATG3 across membrane compartments. Antisense oligonucleotides (ASOs) targeting cryptic exon restore ATG4B mRNA in TARDBP knockdown cells. We further developed multi-target ASOs targeting TDP-43 binding sequences for a broader effect. Importantly, our ASO based in peptide-PMO conjugates show brain distribution post-IV administration, offering a non-invasive ASO-based treatment avenue for neurodegenerative diseases., (© 2024.

Lafora disease (LD; OMIM#254780) is a rare form of progressive myoclonus epilepsy characterized by the accumulation of insoluble deposits of aberrant glycogen (polyglucosans), named Lafora bodies (LBs), in the brain but also in peripheral tissues. It is assumed that the accumulation of LBs is related to the appearance of the characteristic pathological features of the disease. In mouse models of LD, we and others have reported an increase in the levels of reactive astrocytes and activated microglia, which triggers the expression of the different pro-inflammatory mediators. Recently, we have demonstrated that the TNF and IL-6 inflammatory signaling pathways are the main mediators of the neuroinflammatory phenotype associated with the disease. In this work, we present evidence that the activation of these pathways produces a dysregulation in the levels of different subunits of the excitatory ionotropic glutamatergic receptors (phopho-GluN2B, phospho-GluA2, GluK2) and also an increase in the levels of the GABA transporter GAT1 in the hippocampus of the Epm2b-/- mice. In addition, we present evidence of the presence of activated forms of the Src and Lyn protein kinases in this area. These effects may increase the excitatory glutamatergic signaling and decrease the inhibitory GABAergic tone, leading to hyper-excitability. More importantly, the enhanced production of these subunits occurs in non-neuronal cells such as activated microglia and reactive astrocytes, pointing out a key role of glia in the pathophysiology of LD.

Microgreens constitute natural-based foods with health-promoting properties mediated by the accumulation of glucosinolates (GLs) and phenolic compounds (PCs), although their bioaccessibility may limit their nutritional potential. This work subjected eight Brassicaceae microgreens to in vitro gastrointestinal digestion and large intestine fermentation before the metabolomics profiling of PCs and GLs. The application of multivariate statistics effectively discriminated among species and their interaction with in vitro digestion phases. The flavonoids associated with arugula and the aliphatic GLs related to red cabbage and cauliflower were identified as discriminant markers among microgreen species. The multi-omics integration along in vitro digestion and fermentation predicted bioaccessible markers, featuring potential candidates that may eventually be responsible for these functional foods' nutritional properties. This combined analytical and computational framework provided a promising platform to predict the nutritional metabolome-wide outcome of functional food consumption, as in the case of microgreens., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023.

This multicenter study investigates the incidence and predictors of cardiac events (CE) following allo-HCT with PTCY in 453 AML patients. CE occurred in 57 (12.3%) patients within a median of 52 days (IQR: 13-289), with day 100 and 5-year cumulative incidences of 7.7% and 13.5%. Early (first 100 days) and late CE occurred at rates of 7.7% and 4.8%. The most prevalent CE were heart failure (n = 18, 31.6%), pericardial complications (n = 16, 28.1%), and arrhythmia (n = 14, 24.6%). The proportions of patients older than 55 years (64.9% vs. 46.1%, P = 0.010), with hypertension (36.8% vs. 18.4%, P = 0.001) and dyslipidemia (28.1% vs. 11.1%, P = 0.001) were higher in patients with CE. Patients undergoing haplo-HCT trend to have more CE (68.4% vs. 56.8%, P = 0.083). The multivariate regression analysis revealed that only hypertension (HR 1.88, P = 0.036) and dyslipidemia (HR 2.20, P = 0.018) were predictors for CE, with no differences according to donor type (haplo-HCT vs. others: HR 1.33, P = 0.323). Among the 57 patients with CE, the mortality rate was 12.2%. Notably, the diagnosis of CE negatively impacted NRM (HR 2.57, P = 0.011) and OS (HR 1.80, P = 0.009), underscoring necessity of aggressively treating cardiovascular risk factors, and implementing post-transplant cardiac monitoring protocols to prevent these complications., (© 2024.

Metal phosphonate-carboxylate compounds represent a promising class of materials for proton conduction applications. This study investigates the structural, thermal, and proton conduction properties of three groups of lanthanide-based compounds derived from 5-(dihydroxyphosphoryl)isophthalic acid (PiPhtA). The crystal structures, solved ab initio from X-ray powder diffraction data, reveal that groups Ln-I , Ln[O 3 P-C 6 H 3 (COO)(COOH)(H 2 O) 2 ] (Ln = La, Pr), and Ln-II , Ln 2 {[O 3 P-C 6 H 3 (COO)(COOH)] 2 (H 2 O) 4 }·2H 2 O (Ln = La, Pr, Eu), exhibit three-dimensional frameworks, while group Ln-III , Ln[O 3 P-C 6 H 3 (COO)(COOH)(H 2 O)] (Ln = Yb), adopts a layered structure with unbonded carboxylic groups oriented toward the interlayer region. All compounds feature carboxylic groups and coordinating water molecules. Impedance measurements demonstrate that these materials exhibit water-mediated proton conductivity, initially following a vehicle-type proton-transfer mechanism. Upon exposure to ammonia vapors from a 14 or 28% aqueous solution, compounds from groups II and III adsorb ammonia and water, leading to an enhancement in proton conductivity consistent with a Grotthuss-type proton-transfer mechanism. Notably, group II of the studied compounds undergoes the formation of a new expanded phase through the internal reaction of carboxylic groups with ammonia, coexisting with the as-synthesized phase. This postsynthetic modification results in a significant increase in proton conductivity, from approximately ∼5 × 10 -6 to ∼10 -4 S·cm -1 at 80 °C and 95% relative humidity (RH), attributed to a mixed intrinsic/extrinsic contribution. Remarkably, the NH 3 (28%)-exposed Yb-III compound achieves an enhancement in proton conductivity, reaching ∼ 5 × 10 -3 S·cm -1 at 80 °C and 95% RH, primarily through an extrinsic contribution., Competing Interests: The authors declare no competing financial interest., (© 2024 The Authors.

Over the past decade, our research group has found that plant responses to combined abiotic stresses are unique and cannot be inferred from studying plants exposed to individual stresses. Understanding how adaptative plant mechanisms integrate from stress perception to biochemical and physiological adjustments is a major challenge in abiotic stress signaling studies. Considering abscisic acid (ABA) as a key regulator in plant abiotic stress responses, in our study, ABA-deficient plants (flc) exposed to single or combined salinity and heat stresses were evaluated and different -omics analyses were conducted. Significant changes in biomass, photosynthesis, ions, transcripts, and metabolites occurred in mutant plants under single or combined stresses. Exogenous ABA application in flc mutants did not fully recover plant phenotypes or metabolic levels but induced cellular reprogramming with changes in specific markers. Multi-omics analysis aimed to identify ABA-dependent, ABA-independent, or stress-dependent markers in plant responses to single or combined stresses. We demonstrated that studying different -omics as a whole led to the identification of specific markers for each stress condition that were not detectable when each -omic was studied individually. This resource article provides an important and novel reference for scientists working in the field of plant abiotic stress. Future exploration of the transcriptomic, ionomic and metabolomic data presented in this study could lead to the identification of new pathways and genes associated with ABA signaling processes. These findings may be utilized to enhance crop resilience to heat waves, salinity, and their combination, contributing to addressing food security challenges in a climate change scenario., (© The Author(s) 2024.

Viroids are pathogenic noncoding RNAs that completely rely on their host molecular machinery to accomplish their life cycle. Several interactions between viroids and their host molecular machinery have been identified, including interference with epigenetic mechanisms such as DNA methylation. Despite this, whether viroids influence changes in other epigenetic marks such as histone modifications remained unknown. Epigenetic regulation is particularly important during pathogenesis processes because it might be a key regulator of the dynamism of the defense response. Here we have analyzed the changes taking place in Cucumis sativus (cucumber) facultative and constitutive heterochromatin during hop stunt viroid (HSVd) infection using chromatin immunoprecipitation (ChIP) of the two main heterochromatic marks: H3K9me2 and H3K27me3. We find that HSVd infection is associated with changes in both H3K27me3 and H3K9me2, with a tendency to decrease the levels of repressive epigenetic marks through infection progression. These epigenetic changes are connected to the transcriptional regulation of their expected targets, genes, and transposable elements. Indeed, several genes related to the defense response are targets of both epigenetic marks. Our results highlight another host regulatory mechanism affected by viroid infection, providing further information about the complexity of the multiple layers of interactions between pathogens/viroids and hosts/plants., (© 2024 The Author(s).

The dysfunction of TAR DNA-binding protein 43 (TDP-43) is implicated in various neurodegenerative diseases, though the specific contributions of its toxic gain-of-function versus loss-of-function effects remain unclear. This study investigates the impact of TARDBP loss on cellular metabolism and viability using human-induced pluripotent stem cell-derived motor neurons and HeLa cells. TARDBP silencing led to reduced metabolic activity and cell growth, accompanied by neurite degeneration and decreased oxygen consumption rates in both cell types. Notably, TARDBP depletion induced a metabolic shift, impairing ATP production, increasing metabolic inflexibility, and elevating free radical production, indicating a critical role for TDP-43 in maintaining cellular bioenergetics. Furthermore, TARDBP loss triggered non-apoptotic cell death, increased ACSL4 expression, and reprogrammed lipid metabolism towards lipid droplet accumulation, while paradoxically enhancing resilience to ferroptosis inducers. Overall, our findings highlight those essential cellular traits such as ATP production, metabolic activity, oxygen consumption, and cell survival are highly dependent on TARDBP function., Competing Interests: Declaration of competing interest To whom it may be of interest.

Simpson-Golabi-Behmel syndrome (SGBS) is a rare congenital overgrowth condition characterized by macrosomia, macroglossia, coarse facial features, and development delays. It is caused by pathogenic variants in the GPC3 gene on chromosome Xq26.2. Here, we performed a comprehensive literature review and phenotyping of known patients with molecularly confirmed SGBS and reviewed a novel cohort of 22 patients. Using these data, we characterized the tumor risk for Wilms tumor and hepatoblastoma to suggest appropriate screening for this patient population. In addition, we discuss the phenotypic overlap between SGBS and Beckwith-Wiedemann Spectrum., (© 2024 The Author(s). American Journal of Medical Genetics Part A published by Wiley Periodicals LLC.)

Non-immune hydrops fetalis (NIHF) is a rare entity characterized by excessive accumulation of fluid within the fetal extravascular compartments and body cavities. Here we present two intrauterine fetal demises with NIHF presenting with oligohydramnios, cystic hygroma, pleural effusion, and generalized hydrops with predominance of subcutaneous edema. The fetuses also presented with ascites, severe and precocious IUGR and skeletal anomalies. Whole exome sequencing was applied in order to screen for a possible genetic cause. The results identified biallelic variants in MYBBP1A in both fetuses. A previous report described another case with a similar phenotype having compound heterozygous variants in the same gene. The protein encoded by MYBBP1A is involved in several cellular processes including the synthesis of ribosomal DNA, the response to nucleolar stress, and tumor suppression. Our functional protein analysis through immunohistochemistry indicates that MYBBP1A is a gene expressed during fetal stages. Altogether, we concluded that MYBBP1A is associated with the development of hydrops fetalis. More cases and further studies are necessary to understand the role of this gene and the mechanism associated with NIHF., (© 2024 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Carotenoids, known for their antioxidant properties, have garnered significant attention for their potential antitumour activities. This comprehensive review aims to elucidate the diverse mechanisms by which carotenoids exert antitumour effects, focusing on both well-established and novel findings. We explore their role in inducing apoptosis, inhibiting cell cycle progression and preventing metastasis by affecting oncogenic and tumour suppressor proteins. The review also explores the pro-oxidant function of carotenoids within cancer cells. In fact, although their overall contribution to cellular antioxidant defences is well known and significant, some carotenoids can exhibit pro-oxidant effects under certain conditions and are able to elevate reactive oxygen species (ROS) levels in tumoural cells, triggering mitochondrial pathways that would lead to cell death. The final balance between their antioxidant and pro-oxidant activities depends on several factors, including the specific carotenoid, its concentration and the redox environment of the cell. Clinical trials are discussed, highlighting the conflicting results of carotenoids in cancer treatment and the importance of personalized approaches. Emerging research on rare carotenoids like bacterioruberin showcases their superior antioxidant capacity and selective cytotoxicity against aggressive cancer subtypes, such as triple-negative breast cancer. Future directions include innovative delivery systems, novel combinations and personalized treatments, aiming to enhance the therapeutic potential of carotenoids. This review highlights the promising yet complex landscape of carotenoid-based cancer therapies, calling for continued research and clinical exploration.

Background/Objectives: Immune effector cell-associated hematotoxicity (ICAHT) is a frequent adverse event after chimeric antigen receptor (CAR)-T cell therapy. Grade ≥ 3 thrombocytopenia occurs in around one-third of patients, and many of them become platelet transfusion-dependent. Eltrombopag is a thrombopoietin receptor agonist (TPO-RA) able to accelerate megakaryopoiesis, which has been used successfully in patients with bone marrow failure and immune thrombocytopenia (ITP). Its role in managing thrombocytopenia and other cytopenias in CAR-T cell-treated patients has been scarcely addressed. Our aim was to report the safety and efficacy of this approach in patients included in the Spanish Group for Hematopoietic Transplantation and Cellular Therapy (GETH-TC) registry. Methods: This is a retrospective, multicenter, observational study. Patients who developed platelet transfusion dependence subsequently to CAR-T cells and received eltrombopag to improve platelet counts were recruited in 10 Spanish hospitals. Results: Thirty-eight patients were enrolled and followed up for a median (interquartile range [IQR]) of 175 (99, 489) days since CAR-T cell infusion. At the moment eltrombopag was indicated, 18 patients had thrombocytopenia and another severe cytopenia, while 8 patients had severe pancytopenia. After 32 (14, 38) days on eltrombopag, 29 (76.3%) patients recovered platelet transfusion independence. The number of platelet units transfused correlated with the time needed to restore platelet counts higher than 20 × 10 9 /L (Rho = 0.639, p < 0.001). Non-responders to eltrombopag required more platelet units (58 [29, 69] vs. 12 [6, 26] in responders, p = 0.002). Nineteen out of twenty-three (82.6%) patients recovered from severe neutropenia after 22 (11, 31) days on eltrombopag. Twenty-nine out of thirty-five (82.9%) patients recovered red blood cell (RBC) transfusion independence after 29 (17, 44) days. Seven patients recovered all cell lineages while on treatment. No thromboembolic events were reported. Only two transient toxicities (cholestasis, hyperbilirubinemia) were reported during eltrombopag treatment, none of which compelled permanent drug withdrawal. Conclusions: Eltrombopag could be safely used to manage thrombocytopenia and accelerate transfusion independence in CAR-T cell-treated patients.

Introduction and Objectives: Impact of gender on long-term outcomes after transcatheter aortic valve implantation (TAVI) remains uncertain. We aimed to investigate gender-specific differences in TAVI and its impact on outcomes., Methods: This analysis used data from the prospective Spanish TAVI registry, which included consecutive TAVI patients treated in 46 Spanish centers from 2009 to 2021. The primary endpoint was all-cause mortality at 12 months. Secondary endpoints included in-hospital and 30-day mortality and TAVI-related complications. Adjusted logistic and Cox regression analyses were performed., Results: The study included 12 253 consecutive TAVI patients with a mean age of 81.2±6.4 years. Women (53.9%) were older, and had a higher STS-PROM score (7.0±7.0 vs 6.2±6.7; P < .001) than men. Overall, the TAVI-related complication rate was similar between women and men, with specific gender-related complications. While women more frequently developed in-hospital vascular complications (13.6% vs 9.8%; P <.001) and cardiac tamponade (1.5% vs 0.6%; P=.009), men showed a higher incidence of permanent pacemaker implantation (14.5% vs 17.4%; P=.009). There was no difference in all-cause mortality either in hospital (3.6% vs 3.6%, adjusted OR, 1.01; 95%CI, 0.83-1.23; P=.902), at 30 days (4.2% vs 4.2%, adjusted OR, 0.90; 95%CI, 0.65-1.25; P=.564) or at 1 year (11% vs 13%, adjusted HR, 0.94; 95%CI, 0.80-1.11; P=.60)., Conclusions: Women treated with TAVI are older and have more comorbidities than men, leading to distinct complications between genders. Nevertheless, all-cause mortality in the short-term and at 1-year was similar between men and women., (Copyright © 2024 Sociedad Española de Cardiología. Published by Elsevier España, S.L.U.

Background: The selection of patients who are going to be admitted to an emergency department observation unit (EDOU) is essential for the good management of these units, intended fundamentally to avoid unnecessary hospitalization of patients. This is especially important when dealing with older patients. It would be important to know what factors are associated with discharge home and to have a clinical predictive scale that appropriately selects older patients who are going to be admitted to an EDOU., Methods: A retrospective cross-sectional study was conducted of all patients ≥65 years of age assisted in 48 Spanish Emergency Departments for 7 consecutive days and were admitted to the EDOU. Demographics-functional, vital signs data and initial laboratory results were analyzed to investigate its association with discharge home and develop and validate a prediction model for discharge home from EDOU. Multivariable logistic regression was performed to develop a prediction model, and a scoring system was created., Results: Among 5457 patients admitted to the EDOU from the emergency room, 2508 (46%) patients were discharged home, and 2949 (54%) were admitted to the hospital. Five variables were strongly associated with discharge home: the absence of fever (adjusted OR: 3.61, 95% CI:1.53-8.54), Glasgow Coma Scale score of 15 points (2.80, 1.63-4.82), absence of tachypnea (2.51, 1.74-3.64) or leukocytosis (2.07, 1.70-2.52) and oxygen saturation >94% (2.00, 1.64-2.43). The final model achieved an area under the receiver operating characteristic curve of 0.648 (IC95% = 0.627-0.668) in the development cohort and 0.635 (0.614-0.656) in the validation cohort., Conclusions: There are factors associated with a greater probability of discharge home of older patients admitted to EDOUs. Prediction at the individual level remains elusive, as the best model obtained in this study did not have sufficient validity to be applied in the clinical setting., (© 2024 John Wiley & Sons Ltd.)

Background: SmartAction-VR uses virtual reality to simulate daily life tasks and assess cognitive performance based on the multi-errand paradigm. This study explored whether this new task could provide insights into the executive functioning of children and adolescents with ADHD in their everyday activities., Methods: A cross-sectional study was conducted between November 2021 and December 2022. It consisted of one session and was divided into two parts (cognitive tests; and SmartAction-VR). The sample comprised 76 children and adolescents with a median age (IQR) of 13 (11-14) years and an age range of 9-17 years. Of these participants, 60.50% ( n = 46) were males. Out of this sample, 40 participants were in the ADHD group and 36 were in the neurotypical group. The following instruments were used: Waisman Activities of Daily Living Scale, Assessment of Sensory Processing and Executive Functioning, Pediatric Simulator Disease Questionnaire, Digit span subtest, Stroop test, NEPSY-II Subtest of Auditory Attention and Cognitive Flexibility, Trail Making Test, Zoo Map Test, and SmartAction-VR., Results: The ADHD group demonstrated lower accuracy (U = 406, p = 0.010), higher values for total errors (U = 292, p = 0.001), more commissions (U = 417, p = 0.003), new actions (U = 470, p = 0.014), and forgetting actions (U = 406, p = 0.010), as well as fewer perseverations compared to the neurotypical group (U = 540.5, p = 0.029). Additionally, participants who forgot more actions were found to have lower independence in daily life (r = -0.281, p = 0.024)., Conclusions: The correlations between the results of SmartAction-VR and activities of daily living, as well as cognitive tests, suggest that this new task could be useful for evaluating executive functioning in daily life.

Molecular cavities that mimic natural metalloenzymes have shown the potential to trap elusive reaction intermediates. Here, we demonstrate the formation of a rare yet stable Fe(IV)-superoxo intermediate at room temperature subsequent to dioxygen binding at the Fe(III) site of a (Et 4 N) 2 [Fe III (Cl)(bTAML)] complex confined inside the hydrophobic interior of a water-soluble Pd 6 L 4 12+ nanocage. Using a combination of electron paramagnetic resonance, Mössbauer, Raman/IR vibrational, X-ray absorption, and emission spectroscopies, we demonstrate that the cage-encapsulated complex has a Fe(IV) oxidation state characterized by a stable S = 1/2 spin state and a short Fe-O bond distance of ∼1.70 Å. We find that the O 2 reaction in confinement is reversible, while the formed Fe(IV)-superoxo complex readily reacts when presented with substrates having weak C-H bonds, highlighting the lability of the O-O bond. We envision that such optimally trapped high-valent superoxos can show new classes of reactivities catalyzing both oxygen atom transfer and C-H bond activation reactions.

Objectives: To assess whether dementia is an independent predictor of death after a hospital emergency department (ED) visit by older adults with or without a COVID-19 diagnosis during the first pandemic wave., Method: We used data from the EDEN-Covid (Emergency Department and Elderly Needs during Covid) cohort formed by all patients ≥65 years seen in 52 Spanish EDs from March 30 to April 5, 2020. The association of prior history of dementia with mortality at 30, 180 and 365 d was evaluated in the overall sample and according to a COVID-19 or non COVID diagnosis., Results: We included 9,770 patients aged 78.7 ± 8.3 years, 51.1% men, 1513 (15.5%) subjects with prior history of dementia and 3055 (31.3%) with COVID-19 diagnosis. 1399 patients (14.3%) died at 30 d, 2008 (20.6%) at 180 days and 2456 (25.1%) at 365 d. The adjusted Hazard Ratio (aHR) for age, sex, comorbidity, disability and diagnosis for death associated with dementia were 1.16 (95% CI 1.01-1.34) at 30 d; 1.15 at 180 d (95% CI 1.03-1.30) and 1.19 at 365 d (95% CI 1.07-1.32), p  < .001. In patients with COVID-19, the aHR were 1.26 (95% CI: 1.04-1.52) at 30 days; 1.29 at 180 d (95% CI: 1.09-1.53) and 1.35 at 365 d (95% CI: 1.15-1.58)., Conclusion: Dementia in older adults attending Spanish EDs during the first pandemic wave was independently associated with 30-, 180- and 365-day mortality. This impact was lower when adjusted for age, sex, comorbidity and disability, and was greater in patients diagnosed with COVID-19.

Objective:  Surgical intervention in pediatric patients can cause variable degrees of psychological stress with potential consequences in the perioperative period and even in the long term, after hospital discharge in the form of behavioral changes days and months later. The aim of our study was to determine which preoperative preparation strategy reduces postoperative maladaptive behavioral changes in children undergoing ambulatory pediatric surgery., Materials and Methods:  This prospective observational study included 638 pediatric American Society of Anesthesiologists physical status I or II patients who underwent ambulatory pediatric surgery. They were grouped into four preoperative preparation groups: not premedicated (NADA), premedicated with midazolam (MDZ), parental presence during induction of anesthesia (PPIA), and parental presence during induction of anesthesia and premedicated with midazolam (PPIA + MDZ). All patients included in the study were contacted by telephone during 1 year posthospital discharge to assess the postoperative maladaptive behavioral changes using the Posthospitalization Behavior Questionnaire (PHBQ). We performed a multivariate analysis to evaluate the influence of type of preparation and behavioral changes., Results:  Patients in the PPIA and PPIA + MDZ preparation groups presented less postoperative maladaptive behavioral changes compared to patients in the NADA and MDZ groups (odds ratio [OR]: 1.8 [1.1-2.8] and OR 2.2 [1.03-4.49]) during the first week and first month. The intensity of emergence delirium measured by the Pediatric Anesthesia Emergence Delirium (PAED) scale increases the probability of postoperative maladaptive behavioral changes (OR: 1.05 [1.006-1.103])., Conclusion:  The presence of parents during induction of anesthesia (PPIA and PPIA + MDZ) is a very effective strategy in reducing postoperative behavioral changes. These benefits are more significant in children under 5 years of age., Competing Interests: None declared., (Thieme. All rights reserved.)

Sargassum muticum (SM) poses a serious environmental issue since it is a fast-expanding invasive species occupying key areas of the European shoreline, disrupting the autochthonous algae species, and disturbing the ecosystem. This problem has concerned the general population and the scientific community. Nevertheless, as macroalgae are recognized as a source of bioactive molecules, the abundance of SM presents an opportunity as a raw material. In this work, response surface methodology (RSM) was applied as a tool for the optimization of the extraction of bioactive compounds from SM by microwave-assisted extraction (MAE). Five different parameters were used as target functions: yield, total phenolic content (TPC); and the antioxidant measurements of 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity (DPPH), 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS), and β-carotene bleaching (BC). After the optimal extraction conditions were determined (time = 14.00 min; pressure = 11.03 bar; ethanol = 33.31%), the chemical composition and bioactivity of the optimum extract was evaluated to appraise its antioxidant capability to scavenge reactive species and as a potential antibacterial, antidiabetic, antiproliferation, and neuroprotective agent. The results lead to the conclusion that MAE crude extract has bioactive properties, being especially active as an antiproliferation agent and as a nitric oxide and superoxide radical scavenger.

The chemical composition of Parmigiano Reggiano (PR) hard cheese can be significantly affected by different factors across the dairy supply chain, including ripening, altimetric zone, and rind inclusion levels in grated hard cheeses. The present study proposes an untargeted metabolomics approach combined with machine learning chemometrics to evaluate the combined effect of these three critical parameters. Specifically, ripening was found to exert a pivotal role in defining the signature of PR cheeses, with amino acids and lipid derivatives that exhibited their role as key discriminant compounds. In parallel, a random forest classifier was used to predict the rind inclusion levels (> 18%) in grated cheeses and to authenticate the specific effect of altimetry dairy production, achieving a high prediction ability in both model performances (i.e., ∼60% and > 90%, respectively). Overall, these results open a novel perspective to identifying quality and authenticity markers metabolites in cheese., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author(s).

Purpose: Ocular ischemic syndrome can be the first and only hint of life-threatening carotid artery disease. The early recognition of carotid stenosis-related retinal signs, as well as the comprehension of the pathophysiology behind retinal changes could become relevant for physicians to predict the risk of stroke. The aim of this study is to assess the carotid artery disease-induced early structural retinochoroidal changes by means of swept-source optical coherence tomography (SS-OCT)., Methods: A prospective observational study was conducted in 72 eyes with carotid stenosis. According to the degree of stenosis, the participants were divided into a normal group (34 eyes), a mild-moderate stenosis group (22 eyes), a severe stenosis group (16 eyes). SS-OCT and OCTA were performed to scan macular fovea. Central macular thickness (CMT), subfoveal choroidal thickness (SCT) and foveal avascular zona (FAZ) area were the major measurements for our study., Results: CMT was significantly thicker in group 3 when compared to group 2 and 1. SCT was significantly thinner in group 3 vs group 1, being thicker in group 2 when compared to group 1. No significant differences were obtained when comparing FAZ in the superficial and middle capillary plexus although it was significant when comparing the FAZ in the deep capillary plexus between group 1 and 3., Conclusion: internal carotid artery stenosis greater than 70% leads to a significant increase in CMT and a decrease in SCT prior the development of clinical findings of ocular ischemia syndrome., Competing Interests: Declaration of conflicting interestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Human prion diseases are rare, transmissible and often rapidly progressive dementias. The most common type, sporadic Creutzfeldt-Jakob disease (sCJD), is highly variable in clinical duration and age at onset. Genetic determinants of late onset or slower progression might suggest new targets for research and therapeutics. We assembled and array genotyped sCJD cases diagnosed in life or at autopsy. Clinical duration (median:4, interquartile range (IQR):2.5-9 (months)) was available in 3,773 and age at onset (median:67, IQR:61-73 (years)) in 3,767 cases. Phenotypes were successfully transformed to approximate normal distributions allowing genome-wide analysis without statistical inflation. 53 SNPs achieved genome-wide significance for the clinical duration phenotype; all of which were located at chromosome 20 (top SNP rs1799990, pvalue = 3.45x10-36, beta = 0.34 for an additive model; rs1799990, pvalue = 9.92x10-67, beta = 0.84 for a heterozygous model). Fine mapping, conditional and expression analysis suggests that the well-known non-synonymous variant at codon 129 is the obvious outstanding genome-wide determinant of clinical duration. Pathway analysis and suggestive loci are described. No genome-wide significant SNP determinants of age at onset were found, but the HS6ST3 gene was significant (pvalue = 1.93 x 10-6) in a gene-based test. We found no evidence of genome-wide genetic correlation between case-control (disease risk factors) and case-only (determinants of phenotypes) studies. Relative to other common genetic variants, PRNP codon 129 is by far the outstanding modifier of CJD survival suggesting only modest or rare variant effects at other genetic loci., Competing Interests: Stéphane Haik reports grants from Santé Publique France, during the conduct of the study; grants from LFB Biomedicaments, grants from Institut de Recherche Servier, grants from MedDay Pharmaceuticals, outside the submitted work; In addition, Stéphane Haik has a patent Method for treating prion diseases (PCT/EP2019/070457) pending.

Combined thrombophilia represents 7.8-8.3% of the patients with thrombophilia and confers a higher risk for thrombosis development and recurrence. Here, we present a 17-year-old boy carrier of three congenital thrombophilias, two severe (type I antithrombin deficiency and type I protein S deficiency) and one prothrombotic polymorphism (prothrombin G20210A), all in heterozygosis. He developed an extensive deep venous thrombosis in lower left limb, reaching proximal inferior vena cava and contralateral iliac vein, in the setting of prolonged rest. Endovascular therapy with local thrombolytic agent infusion followed by mechanical thrombectomy was performed, achieving a favorable clinical and radiological evolution. Antithrombin replacement to achieve levels between 80% and 120% with heparin administration was used during the endovascular procedure. The patient is currently asymptomatic and maintains indefinite anticoagulation with warfarin, keeping an appropriate anticoagulation range (international normalized range between 2.5 and 3.5)., Competing Interests: The authors declare no conflicts of interest in this work., (© 2024 Marco-Rico et al.)

Background: Incomplete revascularization (ICR) has been associated with a worse prognosis after a percutaneous coronary intervention (PCI). In NSTEMI patients with multivessel disease (MVD) however, the benefit of a complete revascularization (CR) remains unclear., Methods: Patients presenting with an NSTEMI and MVD were selected from the global e-ULTIMASTER registry and grouped according to completeness of revascularization at index hospitalization discharge. The primary endpoint was the patient oriented composite endpoint (POCE) defined as all death, any myocardial infarction, and any revascularization at 1 year. Target lesion failure (TLF) was defined as the composite of cardiac death, target vessel related myocardial infarction and clinically driven target lesion revascularization. Inverse propensity score weighting (IPSW) was performed to harmonize the patient's baseline characteristics between the groups., Results: CR was achieved in 1800 patients (47.0 %) and ICR in 2032 patients (53.0 %). The incidence of POCE at 1 year was lower in the CR group compared to the ICR group: 7.0 % vs. 12.9 %, p < 0.0001. Similarly for TLF at 1 year: 3.6 % vs. 5.5 %, p < 0.01. After IPSW, the incidence of POCE was 7.7 % vs. 12.0 %, p < 0.0001, due to a lower all-cause mortality: 2.7 % vs. 4.2 %, p = 0.02 and less revascularizations: 4.9 % vs. 7.9 %, p < 0.001. The incidence of TLF was no longer statistically significant: CR 3.9 % vs. IR 5.0 %, p = 0.10., Conclusions: Patients with a NSTEMI and multi vessel disease undergoing a percutaneous coronary revascularization with a complete revascularization during index hospitalization have better 1-year clinical outcomes. Randomized studies are warranted to confirm these results., Competing Interests: Declaration of competing interest None of the authors reported a conflict of interest related to this manuscript., (Copyright © 2024 Elsevier Ltd.

In recent years, the search for novel natural-based ingredients by food and related industries has sparked extensive research aimed at discovering new sources of functional molecules. Camellia japonica , traditionally known as an ornamental plant, has gained attention due to its diverse array of bioactive compounds with potential industrial applications. Although C. japonica flowers are edible, their phytochemical profile has not been thoroughly investigated. In this study, a phenolic profile screening through an HPLC-ESI-QQQ-MS/MS approach was applied to C. japonica flower extracts, revealing a total of 36 compounds, including anthocyanins, curcuminoids, dihydrochalcones, dihydroflavonols, flavonols, flavones, hydroxybenzoic acids, hydroxycinnamic acids, isoflavonoids, stilbenes, and tyrosols. Following extract profiling, their bioactivity was assessed by means of in vitro antioxidant, antimicrobial, cytotoxic, and neuroprotective activities. The results showed a multifaceted high correlation of phenolic compounds with all the tested bioactivities according to Pearson's correlation analysis, unraveling the potential of C. japonica flowers as promising sources of nutraceuticals. Overall, these findings provide insight into the valorization of C. japonica flowers from different unexplored cultivars thus diversifying their industrial outcome.

Objective: Analyse the association between the use of diagnostic tests and the characteristics of older patients 65 years of age or more who consult the emergency department (ED)., Methods: We performed an analysis of the EDEN cohort that includes patients who consulted 52 Spanish EDs. The association of age, sex, and ageing characteristics with the use of diagnostic tests (blood tests, electrocardiogram (ECG), microbiological cultures, X-ray, computed tomography, ultrasound, invasive techniques) was studied. The association was analysed by calculating the adjusted odds ratios (aOR) and their 95 % confidence intervals (CI) using a logistic regression model., Results: A total of 25,557 patients were analysed. There was an increase in the use of diagnostic tests based on age, with an aOR for blood test of 1.805 (95 %CI 1.671 - 1.950), ECG 1.793 (95 %CI 1.664 - 1.932) and X-ray 1.707 (95 %CI 1.583 - 1.840) in the group of 85 years or more. The use of diagnostic tests is lower in the female population. Most ageing characteristics (cognitive impairment, previous falls, polypharmacy, dependence, and comorbidity) were independently associated with increased use of diagnostic tests., Conclusions: Age, and the characteristics of ageing itself are generally associated with a greater use of diagnostic tests in the ED., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 College of Emergency Nursing Australasia.

Multiple system atrophy (MSA) is an adult-onset, sporadic synucleinopathy characterized by parkinsonism, cerebellar ataxia, and dysautonomia. The genetic architecture of MSA is poorly understood, and treatments are limited to supportive measures. Here, we performed a comprehensive analysis of whole genome sequence data from 888 European-ancestry MSA cases and 7,128 controls to systematically investigate the genetic underpinnings of this understudied neurodegenerative disease. We identified four significantly associated risk loci using a genome-wide association study approach. Transcriptome-wide association analyses prioritized USP38-DT, KCTD7, and lnc-KCTD7-2 as novel susceptibility genes for MSA within these loci, and single-nucleus RNA sequence analysis found that the associated variants acted as cis-expression quantitative trait loci for multiple genes across neuronal and glial cell types. In conclusion, this study highlights the role of genetic determinants in the pathogenesis of MSA, and the publicly available data from this study represent a valuable resource for investigating synucleinopathies., Competing Interests: Declaration of interests T.G.B. is a consultant for Aprinoia Therapeutics, Vivid Genomics, and Avid Radiopharmaceutical and is a scientific advisory board member for Vivid Genomics.

The increasing trend regarding the use of plastics has arisen an exponential concern on the fate of their derived products to the environment. Among these derivatives, microplastics and nanoplastics (MNPs) have been featured for their associated environmental impact due to their low molecular size and high surface area, which has prompted their ubiquitous transference among all environmental interfaces. Due to the heterogenous chemical composition of MNPs, the study of these particles has focused a high number of studies, as a result of the myriad of associated physicochemical properties that contribute to the co-transference of a wide range of contaminants, thus becoming a major challenge for the scientific community. In this sense, both primary and secondary MNPs are well-known to be adscribed to industrial and urbanized areas, from which they are massively released to the environment through a multiscale level, involving the atmosphere, hydrosphere, and lithosphere. Consequently, much research has been conducted on the understanding of the interconnection between those interfaces, that motivate the spread of these contaminants to biological systems, being mostly represented by the biosphere, especially phytosphere and, finally, the anthroposphere. These findings have highlighted the potential hazardous risk for human health through different mechanisms from the environment, requiring a much deeper approach to define the real risk of MNPs exposure. As a result, there is a gap of knowledge regarding the environmental impact of MNPs from a high-throughput perspective. In this review, a metabolomics-based overview on the impact of MNPs to all environmental interfaces was proposed, considering this technology a highly valuable tool to decipher the real impact of MNPs on biological systems, thus opening a novel perspective on the study of these contaminants., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author(s).

The elderly population frequently consults the emergency department (ED). This population could have greater use of EDs and hospital health resources. The EDEN cohort of patients aged 65 years or older visiting the ED allowed this association to be investigated. To analyse the association between healthcare resource use and the characteristics of patients over 65 years of age who consult hospital EDs. We performed an analysis of the EDEN cohort, a retrospective, analytical, and multipurpose registry that includes patients over 65 years of age who consulted in 52 Spanish EDs. The impact of age, sex, and characteristics of ageing on the following outcomes was studied: need for hospital admission (primary outcome) and need for observation, stay in the ED > 12 h, prolonged hospital stay > 7 days, need for intensive care unit (ICU) and return to the ED at 30 days related to the index visit (secondary outcomes). The association was analysed by calculating the adjusted odds ratios (aOR) and their 95% confidence intervals (CI), using a logistic regression model. A total of 25,557 patients with a mean age of 78.3 years were analysed, 45% were males. Of note was the presence of comorbidity, a Charlson index ≥ 3 (33%), and polypharmacy (66%). Observation in the ED was required by 26%, 25.4% were admitted to the hospital, and 0.9% were admitted to the ICU. The ED stay was > 12 h in 12.5% and hospital stay > 7 days in 13.5% of cases. There was a progressive increase in healthcare resource use based on age, with an aOR for the need for observation of 2.189 (95% CI 2.038-2.352), ED stay > 12 h 2.136 (95% CI 1.942-2.349) and hospital admission 2.579 (95% CI 2.399-2.772) in the group ≥ 85 years old. Most of the characteristics inherent to ageing (cognitive impairment, falls in the previous 6 months, polypharmacy, functional dependence, and comorbidity) were associated with significant increases in the use of healthcare resources, except for ICU admission, which was less in all the variables studied. Age and the characteristics inherent to ageing are associated with greater use of structural healthcare resources., (© 2024.

Objective: To study factors associated with hospitalization in an unselected population of patients aged 65 years or older treated for syncope in Spanish hospital emergency departments (EDs). To determine the prevalence of adverse events at 30 days in patients discharged home and the factors associated with such events., Methods: We included all patients aged 65 years or older who were diagnosed with syncope during a single week in 52 Spanish EDs, recording patient clinical and ED case management data. We compared the findings between hospitalized patients and those discharged home, following the latter for 30 days. In discharged patients, we explored predictors of a composite adverse-event outcome (occurrence of any of the following: ED revisits, hospitalization related to the index visit, or any-cause death)., Results: A total of 477 patients with syncope were identified; 67 (14%) were admitted, and 5 (7.5%) died. The median (interquartile range) length of hospital stay was 6 days (3-11 days). Comorbidity increased the probability of hospitalization (odds ratio, 2.172; 95% CI, 1.013-4.655). Among the 410 patients (86%) discharged home from the ED, 9.2% experienced an adverse event within 30 days (ED revisits, 8.,1%; hospitalization, 2.2%; death, 1.5%). No factors were associated with the 30-day composite outcome., Conclusions: The majority of patients aged 65 years or older are discharged home from EDs, and 30-day adverse events, while infrequent, are difficult to predict. Hospitalization was related to comorbidity and an absence of cognitive decline.

Nitrogen (N) is the nutrient most applied in agriculture as fertilizer (as nitrate, Nit; ammonium, A; and/or urea, U, forms) and its availability strongly constrains the crop growth and yield. To investigate the early response (24 h) of N-deficient tomato plants to these three N forms, a physiological and molecular study was performed. In comparison to N-deficient plants, significant changes in the transcriptional, metabolomic and ionomic profiles were observed. As a probable consequence of N mobility in plants, a wide metabolic modulation occurred in old leaves rather than in young leaves. The metabolic profile of U and A-treated plants was more similar than Nit-treated plant profile, which in turn presented the lowest metabolic modulation with respect to N-deficient condition. Urea and A forms induced some changes at the biosynthesis of secondary metabolites, amino acids and phytohormones. Interestingly, a specific up-regulation by U and down-regulation by A of carbon synthesis occurred in roots. Along with the gene expression, data suggest that the specific N form influences the activation of metabolic pathways for its assimilation (cytosolic GS/AS and/or plastidial GS/GOGAT cycle). Urea induced an up-concentration of Cu and Mn in leaves and Zn in whole plant. This study highlights a metabolic reprogramming depending on the N form applied, and it also provide evidence of a direct relationship between urea nutrition and Zn concentration. The understanding of the metabolic pathways activated by the different N forms represents a milestone in improving the efficiency of urea fertilization in crops., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Lafora disease (LD; OMIM#254780) is a rare, devastating, and fatal form of progressive myoclonus epilepsy that affects young adolescents and has no treatment yet. One of the hallmarks of the disease is the accumulation of aberrant poorly branched forms of glycogen (polyglucosans, PGs) in the brain and peripheral tissues. The current hypothesis is that this accumulation is causative of the pathophysiology of the disease. Another hallmark of LD is the presence of neuroinflammation. We have recently reported the presence of reactive glia-derived neuroinflammation in LD mouse models and defined the main inflammatory pathways that operate in these mice, mainly TNF and IL-6 signaling pathways. In addition, we described the presence of infiltration of peripheral immune cells in the brain parenchyma, which could cooperate and aggravate the neuroinflammatory landscape of LD. In this work, we have checked the beneficial effect of two compounds with the capacity to ameliorate neuroinflammation and reduce leukocyte infiltration into the brain, namely fingolimod and dimethyl fumarate. Our results indicate a beneficial effect of fingolimod in reducing reactive astrogliosis-derived neuroinflammation and T-lymphocyte infiltration, which correlated with the improved behavioral performance of the treated Epm2b-/- mice. On the contrary, dimethyl fumarate, although it was able to reduce reactive astrogliosis, was less effective in preventing neuroinflammation and T-lymphocyte infiltration and in modifying behavioral tests., (© 2023.
