Demyelination and axonal injury in chronic-progressive Multiple Sclerosis (MS) are presumed to be driven by a neurotoxic bystander effect of meningeal-based myeloid infiltrates. There is an unmet clinical need to attenuate disease progression in such forms of CNS-compartmentalized MS. The failure of systemic immune suppressive treatments has highlighted the need for neuroprotective and repair-inducing strategies. Here, we examined whether direct targeting of CNS myeloid cells and modulating their toxicity may prevent irreversible tissue injury in chronic immune-mediated demyelinating disease. To that end, we utilized the experimental autoimmune encephalomyelitis (EAE) model in Biozzi mice, a clinically relevant MS model. We continuously delivered intracerebroventricularly (ICV) a retinoic acid receptor alpha agonist (RARα), as a potent regulator of myeloid cells, in the chronic phase of EAE. We assessed disease severity and performed pathological evaluations, functional analyses of immune cells, and single-cell RNA sequencing on isolated spinal CD11b+ cells. Although initiating treatment in the chronic phase of the disease, the RARα agonist successfully improved clinical outcomes and prevented axonal loss. ICV RARα agonist treatment inhibited pro-inflammatory pathways and shifted CNS myeloid cells toward neuroprotective phenotypes without affecting peripheral infiltrating myeloid cell phenotypes, or peripheral immunity. The treatment regulated cell-death pathways across multiple myeloid cell populations and suppressed apoptosis, resulting in paradoxically marked increased neuroinflammatory infiltrates, consisting mainly of microglia and CNS / border-associated macrophages. This work establishes the notion of bystander neurotoxicity by CNS immune infiltrates in chronic demyelinating disease. Furthermore, it shows that targeting compartmentalized neuroinflammation by selective regulation of CNS myeloid cell toxicity and survival reduces irreversible tissue injury, and may serve as a novel disease-modifying approach.

INTRODUCTION: Infertility treatment with assisted reproductive technologies (ARTs) has been associated with adverse vascular events in some but not all previous studies. Endothelial damage, prothrombotic factor release, and a higher prevalence of cardiovascular risk factors in those receiving ART have been invoked to explain this association. We sought to explore the relationship between ART and stroke risk using population-level data.
METHODS: We conducted a retrospective cohort study using data from the National Inpatient Sample registry from 2015 to 2020, including all delivery hospitalizations for patients aged 15 to 55 years. The study exposure was use of ART. The primary end point was any stroke defined as ischemic stroke, subarachnoid hemorrhage, intracerebral hemorrhage, or cerebral venous thrombosis during index delivery hospitalization. Individual stroke subtypes (ischemic stroke, subarachnoid hemorrhage, intracerebral hemorrhage, and cerebral venous thrombosis) were evaluated as secondary end points. Standard International Classification of Diseases, Tenth Revision, Clinical Modification algorithms were used to define study exposure, comorbidities, and prespecified end points. In addition to reporting population-level estimates, propensity score adjustment by inverse probability weighting was used to mimic the effects of randomization by balancing baseline clinical characteristics associated with stroke between ART and non-ART users.
RESULTS: Among 19 123 125 delivery hospitalizations identified, patients with prior ART (n=202 815, 1.1%) experienced significantly higher rates of any stroke (27.1/100 000 versus 9.1/100 000), ischemic stroke (9.9/100 000 versus 3.3/100 000), subarachnoid hemorrhage (7.4/100 000 versus 1.6/100 000), intracerebral hemorrhage (7.4/100 000 versus 2.0/100 000), and cerebral venous thrombosis (7.4/100 000 versus 2.7/100 000) in comparison to non-ART users (all P<0.001 for all unadjusted comparisons). Following inverse probability weighting analysis, ART was associated with increased odds of any stroke (adjusted odds ratios, 2.14 (95% CI, 2.02-2.26); P<0.001).
CONCLUSIONS: Using population-level data among patients hospitalized for delivery in the United States, we found an association between ART and stroke after adjustment for measured confounders.

BACKGROUND: The decision to forgo life-sustaining treatment in intensive care units (ICUs) is influenced by ethical, cultural, and medical factors. This study focuses on a population of patients with hospital-acquired bloodstream infections (HABSI) to investigate the association between patient, pathogen, center and country-level factors and these decisions.
METHODS: We analyzed data from the EUROBACT-2 study (June 2019-January 2021) from 265 centers worldwide, focusing on non-COVID-19 patients who died in the hospital or within 28 days after HABSI. We assessed whether death was preceded by a decision to forgo life-sustaining treatment, examining country, center, patient, and pathogen variables. To assess the association of each potentially important variable with the decision to forgo life-sustaining treatment, univariable mixed logistic regression models with a random center effect were performed.
RESULTS: Among 1589 non-COVID-19 patients, 519 (32.7%) died, with 191 (36.8%) following a decision to forgo life-sustaining treatment. Significant geographical differences were observed, with no reported decisions to forgo life-sustaining treatment in African countries and fewer in the Middle East compared to Western Europe, Australia, and Asia. Once a center effect was considered, only health expenditure (Odds ratio 1.79, 95%CI: 1.45-2.21, p < 0.01) and age (Odds ratio 1.02, 95%CI: 1.002-1.05, p = 0.03) were significantly associated with decisions to forgo life-sustaining treatment, while other patient and pathogen factors were not.
CONCLUSION: Economic and regional disparities significantly impact end-of-life decision-making in ICUs. Global policies should consider these disparities to ensure equitable end-of-life care practices.

BACKGROUND & AIMS: Preoperative sarcopenia in gastric cancer is associated with increased postoperative complications and reduced long-term survival. However, the association between postoperative sarcopenia and long-term outcomes remains unclear. Therefore, this study aims to clarify the association between sarcopenia after gastrectomy for gastric cancer and survival outcomes.
METHODS: This retrospective study included 1512 patients aged ≥65 who underwent curative gastric resection for clinical stage I-III primary gastric cancer during 2008-2018. Sarcopenia was assessed preoperatively by measuring arm muscle area and grip strength, which was repeated 1 month after surgery. We compared the clinical characteristics, surgical treatments, and long-term outcomes between the postoperative normal and sarcopenia groups.
RESULTS: Sarcopenia was observed in 173 and 305 patients pre- and postoperatively, respectively. Factors increasing the risk of postoperative sarcopenia included age of ≥75, lower preoperative body mass index, diabetes, and clinical stage II/III gastric cancer. Patients with postoperative sarcopenia after surgery had a significantly lower overall survival rate (hazard ratio [HR] 2.596, p < 0.001). Furthermore, postoperative sarcopenia was linked to decreased overall survival in patients with (HR 2.813, p = 0.002) and without (HR 1.925, p < 0.001) preoperative sarcopenia. Cumulative incidence showed significantly higher rates of deaths due to gastric cancer (HR 1.928, p < 0.001) and other causes (HR 2.736, p < 0.001) in the postoperative sarcopenia group.
CONCLUSIONS: Postoperative sarcopenia in gastric cancer is linked to an increased risk of death due to cancer and other causes, underscoring the importance of perioperative sarcopenia management strategies.
Continuous temperature monitors can be used to collect frequent temperature data over large periods of time. A machine learning system trained with collected temperature data can be used to predict future temperature data for patients. Such predictions can be clinically beneficial for disease states in which fever can be fatal, particularly for those fevers having fast onset. For example, patients undergoing chimeric antigen receptor T-cell (CAR-T) therapy may suffer fevers caused by cytokine release syndrome (CRS). Accordingly, a continuous temperature monitor is used to collect temperature data from CAR-T patients with high risk of CRS (or like patients with high fever risk), and the collected temperature data processed by a machine learning system to predict the patient's future temperature profiles. Results of analysis of the predicted temperature profiles may then be provided to the patient and/or clinician.

Studies reveal that ocular anomalies may also be found in healthy full-term babies. These abnormal ocular findings included subconjunctival haemorrhage, congenital microphthalmos, congenital corneal leukoma, posterior synechia, persistent pupillary membrane, congenital cataract, enlarged C/D ratio, retinal hamartoma versus retinoblastoma, optic nerve defects, macular pigment disorder and non-specific peripheral retinopathy. The highest proportion of these abnormal findings is retinal haemorrhages, accounting for 92% of abnormalities. Most retinal hemorrhages are benign and will finally self-resolve. However, sometimes it takes a long time for the hemorrhage to resolve. Some slow-resolving hemorrhages could obstruct the visual axis and may do great harm to visual development in critical period. Some neonatal eye diseases are time sensitive, such as retinoblastoma, and if found late, the best opportunity for effective treatment is missed, leading to irreversible visual impairment. Newborns are unable to express their discomforts or visual disorders as adults do and only through an examination, the neonatal eye diseases can be detected. Therefore, this screening protocol is designed to screen the otherwise healthy neonates in a multi-center network on neonatal ophthalmopathy and to achieve early diagnosis and timely treatment. All the neonates will undergo eye examination by using RetCam III. The external eye, pupillary light reflex, red reflex, opacity of refractive media, anterior chamber and posterior segments will be examined. The outcomes will be analyzed by a blinded specialist in order to discover serious congenital, hereditary and acquired diseases in the neonatal period of healthy newborns and to improve epidemiological information of neonatal ophthalmopathy. Neonatal ocular examination may play a positive role in promoting paediatric eye health to paediatricians and parents.
A safe and efficacious live-attenuated vaccine is presented, (LAV) VNUA-ASFV-LAVL2, generated by serial passaging of a field isolate (VNUA-ASFV-05L1, genotype II) in porcine alveolar macrophage (PAMs, 65 passages) and an immortalized porcine alveolar macrophage cell line (3D4/21, 55 passages). VNUA-ASFV-LAVL2 can efficiently replicate in both PAMs and 3D4/21 cells. It provides 100% protection, even with the low dose of 102 HAD50, for the vaccinated pigs against the challenge of contemporary pandemic ASFV field isolate. Pigs vaccinated with this LAV at a dose range of 102 to 105 HAD50 remain clinically healthy during both an observation period of immunization and a 28-day observation period of challenge. VNUA-ASFV-LAVL2 is eliminated from blood by 28 days post inoculation (DPI, and from feces or oral fluids by 17 DPI. ASFV-specific IgG antibodies and significant cellular immunity can be detected in vaccinated pigs before an ASFV challenge.
The invention provides a preparation method for a chitosan nanoparticle film spraying agent. Prepared nanoscale chitosan is uniformly dispersed in the chitosan nanoparticle film spraying agent, so that the chitosan nanoparticle film spraying agent can be well applied to skin wounds to perform the effects of stopping bleeding and sterilizing. Two high-polymer film forming materials, namely PVP and HPMC, are taken as film spraying agent matrixes to prepare a film spraying agent; PVP is safe and nontoxic, has strong adhesion on skin and no irritation, is freely soluble in a polar solvent, has certain viscosity, and is good in film forming property; a small amount of HPMC is soluble in cold water, and HPMC is good in film forming property, and generally taken as an adjuvant and other film forming materials for complex use. A certain proportion of ethanol solution is added in a film spraying agent water solution, so that the film forming agent water solution is sprayed out more smoothly, and the film forming is more uniform. A film spraying solution and a nano-chitosan concentrated solution in the step (4) are heated and then mixed and cooled. According to the process, the film forming time and the drying time can be further shortened, and the use performance of the film spraying agent is optimized.
BACKGROUND: The objective of this study was to develop and validate a nomogram for predicting the risk of an acute complicated course in pediatric patients with Acute Hematogenous Osteomyelitis (AHO).
METHODS: A predictive model was developed based on a dataset of 82 pediatric AHO patients. Clinical data, imaging findings, and laboratory results were systematically collected for all patients. Subsequently, biomarker indices were calculated based on the laboratory results to facilitate a comprehensive evaluation. Univariate and multivariate logistic regression analyses were conducted to identify factors influencing early adverse outcomes in AHO. A nomogram model was constructed based on independent factors and validated internally through bootstrap methods. The discriminative ability, calibration, and clinical utility of the nomogram model were assessed using receiver operating characteristic (ROC) curves, calibration plots, and decision curve analysis (DCA), respectively. The developed nomogram model was compared with previously published A-score and Gouveia scoring systems.
RESULTS: Logistic regression analysis identified delayed source control, suppurative arthritis, albumin on admission, and platelet to lymphocyte ratio (PLR) as independent predictors of early adverse outcomes in pediatric AHO patients. The logistic regression model was formulated as: Log(P) = 7. 667-1.752 × delayed source control - 1.956 × suppurative arthritis - 0.154 × albumin on admission + 0.009 × PLR. The nomogram's AUC obtained through Bootstrap validation was 0.829 (95% CI: 0.740-0.918). Calibration plots showed good agreement between predictions and observations. Decision curve analysis demonstrated that the model achieved net benefits across all threshold probabilities. The predictive efficacy of our nomogram model for acute complicated course in pediatric AHO patients surpassed that of the A-score and Gouveia scores.
CONCLUSIONS: A predictive model for the acute complicated course of pediatric AHO was established based on four variables: delayed source control, suppurative arthritis, albumin on admission, and PLR. This model is practical, easy to use for clinicians, and can aid in guiding clinical treatment decisions.
BACKGROUND: The notable decline in the number of Tregs within Necrotizing enterocolitis (NEC) intestinal tissues,contribute to excessive inflammation and necrosis, yet the precise underlying factors remain enigmatic. Ferroptosis, a novel cell death stemming from a disrupted lipid redox metabolism, is the focus of this investigation. Specifically, this study delves into the ferroptosis of Treg cells in the context of NEC and observes the protective effects exerted by vitamin E intervention, which aims to mitigate ferroptosis of Treg cells.
METHODS: To investigate the reduction of Treg cells in NEC intestine, we analyzed its association with ferroptosis from multiple angles. We constructed a mouse with a specific knockout of Gpx4 in Treg cells, aiming to examine the impact of Treg cell ferroptosis on NEC intestinal injury and localized inflammation. Ultimately, we employed vitamin E treatment to mitigate ferroptosis in NEC intestine's Treg cells, monitoring the subsequent amelioration in intestinal inflammatory damage.
RESULTS: The diminution of Treg cells in NEC is attributed to ferroptosis stemming from diminished GPX4 expression. Gpx4-deficient Treg cells exhibit impaired immunosuppressive function and are susceptible to ferroptosis. This ferroptosis of Treg cells exacerbates intestinal damage and inflammatory response in NEC. Notably, Vitamin E can inhibit the ferroptosis of Treg cells, subsequently alleviating intestinal damage and inflammation in NEC. Additionally, Vitamin E bolsters the anti-lipid peroxidation capability of Treg cells by upregulating the expression of GPX4.
CONCLUSION: In the context of NEC, the ferroptosis of Treg cells represents a significant factor contributing to intestinal tissue damage and an exaggerated inflammatory response. GPX4 is pivotal for the viability and functionality of Treg cells. Vitamin E exhibits the capability to mitigate the ferroptosis of Treg cells, thereby enhancing their number and function, which plays a crucial role in mitigating intestinal tissue damage and inflammatory response in NEC.
