NIL10: A New IL10-Receptor Binding Nanoparticle That Induces Cardiac Protection in Mice and Pigs Subjected to Acute Myocardial Infarction through STAT3/NF-kB Activation.

Background: Early response after acute myocardial infarction (AMI) prevents extensive cardiac necrosis, in which inflammation resolution, including expression of anti-inflammatory interleukin-10 (IL-10), may play a key role. (2) Methods: We synthesized NIL10, a micelle-based nanoparticle, to target IL-10 receptor in mice and pigs subjected to AMI. (3) Results: Administration of NIL10 induced cardiac protection of wild-type and IL-10 knockout mice and pigs subjected to AMI. Cardiac protection was not induced in IL-10-receptor null mice, as shown by a significant recovery of cardiac function, in which inflammatory foci and fibrosis were strongly reduced, together with the finding that resolving M2-like macrophage populations were increased after day 3 of reperfusion. In addition, anti-inflammatory cytokines, including IL-4, IL-7, IL-10, IL-13, IL-16, and IL-27 were also elevated. Mechanistically, NIL10 induced activation of the IL-10 receptor/STAT-3 signaling pathway, and STAT3-dependent inhibition of nuclear translocation of pro-inflammatory NF-kB transcription factor. (4) Conclusions: Taken together, we propose using NIL10 as a novel therapeutic tool against AMI-induced cardiac damagepost-print4711 K

Association Between Preexisting Versus Newly Identified Atrial Fibrillation and Outcomes of Patients With Acute Pulmonary Embolism

Background Atrial fibrillation (AF) may exist before or occur early in the course of pulmonary embolism (PE). We determined the PE outcomes based on the presence and timing of AF. Methods and Results Using the data from a multicenter PE registry, we identified 3 groups: (1) those with preexisting AF, (2) patients with new AF within 2 days from acute PE (incident AF), and (3) patients without AF. We assessed the 90-day and 1-year risk of mortality and stroke in patients with AF, compared with those without AF (reference group). Among 16 497 patients with PE, 792 had preexisting AF. These patients had increased odds of 90-day all-cause (odds ratio [OR], 2.81; 95% CI, 2.33-3.38) and PE-related mortality (OR, 2.38; 95% CI, 1.37-4.14) and increased 1-year hazard for ischemic stroke (hazard ratio, 5.48; 95% CI, 3.10-9.69) compared with those without AF. After multivariable adjustment, preexisting AF was associated with significantly increased odds of all-cause mortality (OR, 1.91; 95% CI, 1.57-2.32) but not PE-related mortality (OR, 1.50; 95% CI, 0.85-2.66). Among 16 497 patients with PE, 445 developed new incident AF within 2 days of acute PE. Incident AF was associated with increased odds of 90-day all-cause (OR, 2.28; 95% CI, 1.75-2.97) and PE-related (OR, 3.64; 95% CI, 2.01-6.59) mortality but not stroke. Findings were similar in multivariable analyses. Conclusions In patients with acute symptomatic PE, both preexisting AF and incident AF predict adverse clinical outcomes. The type of adverse outcomes may differ depending on the timing of AF onset.info:eu-repo/semantics/publishedVersio

Treatment with tocilizumab or corticosteroids for COVID-19 patients with hyperinflammatory state: a multicentre cohort study (SAM-COVID-19)

Objectives: The objective of this study was to estimate the association between tocilizumab or corticosteroids and the risk of intubation or death in patients with coronavirus disease 19 (COVID-19) with a hyperinflammatory state according to clinical and laboratory parameters. Methods: A cohort study was performed in 60 Spanish hospitals including 778 patients with COVID-19 and clinical and laboratory data indicative of a hyperinflammatory state. Treatment was mainly with tocilizumab, an intermediate-high dose of corticosteroids (IHDC), a pulse dose of corticosteroids (PDC), combination therapy, or no treatment. Primary outcome was intubation or death; follow-up was 21 days. Propensity score-adjusted estimations using Cox regression (logistic regression if needed) were calculated. Propensity scores were used as confounders, matching variables and for the inverse probability of treatment weights (IPTWs). Results: In all, 88, 117, 78 and 151 patients treated with tocilizumab, IHDC, PDC, and combination therapy, respectively, were compared with 344 untreated patients. The primary endpoint occurred in 10 (11.4%), 27 (23.1%), 12 (15.4%), 40 (25.6%) and 69 (21.1%), respectively. The IPTW-based hazard ratios (odds ratio for combination therapy) for the primary endpoint were 0.32 (95%CI 0.22-0.47; p < 0.001) for tocilizumab, 0.82 (0.71-1.30; p 0.82) for IHDC, 0.61 (0.43-0.86; p 0.006) for PDC, and 1.17 (0.86-1.58; p 0.30) for combination therapy. Other applications of the propensity score provided similar results, but were not significant for PDC. Tocilizumab was also associated with lower hazard of death alone in IPTW analysis (0.07; 0.02-0.17; p < 0.001). Conclusions: Tocilizumab might be useful in COVID-19 patients with a hyperinflammatory state and should be prioritized for randomized trials in this situatio

Induced defenses in olive trees by herbivory mimicry in leaves are modulated by root inoculation with beneficial fungi

1 página - Poster presentado en Iberian Plant Biology 2023. XVIII Portuguese-Spanish Congress on Plant Biology and the XXV Meeting of the Spanish Society of Plant Biology. 9-12 Julio 2023, Braga, Portugal.Plants can activate various defense mechanisms in response to herbivore attack or simulated herbivory such as mechanical wounding. These mechanisms include the expression of resistance related genes and the emission of volatile organic compounds (VOCs). In this study, we investigated the induced defenses in olive (Olea europaea cv. Picual) plants in response to herbivory simulation by mechanical wounding. We confirmed that mechanical stimulation mimicking herbivory wounds efficiently regulated various defense mechanisms and regulatory pathways. Transcriptional analyses by qPCR revealed differential regulation of defense‐related genes. For example, we found a very strong upregulation (+120‐fold change) of the acetone cyanohydrin lyase gene and downregulation of a beta‐1,3‐glucanase gene. Interestingly, root inoculation with the beneficial fungus Trichoderma harzianum modulated the transcriptional regulation of defenses, and increased the expression of HPL gene, coding for a hydroperoxide lyase, involved in VOCs production. Moreover, the herbivory mimic also regulated indirect defences. Phytophagous insects and their natural enemies are attracted to the volatile mixture produced by the plants and use a particular combination of the compounds released for host identification. We detected a change in volatile blends in response to the mechanical wounding. Some compounds known to be involved in the plant defense against chewing insects, such as 1‐heptanol, 2‐nonenal, butanoic acid, hexanoic acid, and pentanoic acid, were only detected in damaged trees. While these compounds contributed in low proportion to the overall blend, it is interesting to note that the main difference was associated to the proportions in which three compounds, belonging to the class known as green leaf volatiles, contributed to global mixes. Thus, hexanal, heptanal and octanal aldehydes, important plant volatiles that contribute to plant defense strategies, had a greater weight in the mixture emitted by the damaged olive trees. Remarkably, inoculation with T. harzianum also had a significant impact on the profiles of the released volatiles, including nonanal aldehyde as a major volatile in the overall blend released after mimicry. Overall, the complex interactions between olive plants, soil microbiota, herbivorous insects, and their natural enemies highlight the importance of studying the role of VOCs and defense genes in orchestrating these interactions, as this information will contribute to developing more sustainable pest management strategies for olive groves.Grant P20‐00139 funded by Consejería de Transformación Económica, Industria, Conocimiento y Universidades, Junta de Andalucía and by “ERDF A way of making Europe

Evaluating IoT-Based Services to Support Patient Empowerment in Digital Home Hospitalization Services

Hospitals need to optimize patient care, as, among other factors, life expectancy has increased due to improvements in sanitation, nutrition, and medicines. Hospitalization-at-home (HaH) could increase admission efficiency, moderate costs, and reduce the demand for beds. This study aimed to provide data on the feasibility, acceptability, and effectiveness of the integration of IoT-based technology to support the remote monitoring and follow-up of patients admitted to HaH units, as well as the acceptability of IoT-based solutions in healthcare processes. The need for a reduction in the number of admission days, the percentage of admissions after discharge, and the actions of the emergency services during admission were the most relevant findings of this study. Furthermore, in terms of patient safety and trust perception, 98% of patients preferred this type of digitally-supported hospitalization model and up to 95% were very satisfied. On the professional side, the results showed a reduction in work overload and an increase in trust when the system was adopted
