Unlabelled: Spontaneous bacterial meningitis (BM) is more common among patients with underlying conditions, but its characteristics in previously healthy patients are not well described. We analyzed the time trends of BM in terms of characteristics, and outcomes in patients without comorbidities.
Patients And Methods: Single-center, prospective observational cohort study of 328 adults with BM hospitalized in a tertiary university hospital in Barcelona (Spain). We compared the features of infections diagnosed in 1982-2000 and 2001-2019. The main outcome measure was in-hospital mortality.
Results: The median age of the patients increased from 37 to 45 years. Meningococcal meningitis significantly diminished (56% versus 31%, < 0.000) whereas listerial meningitis increased (1.2% versus 8%, = 0.004). Systemic complications were more common in the second period, although mortality did not vary significantly between periods (10.4% versus 9.2%). However, after adjusting for relevant variables, infection in the second period was associated with lower risk death.
Conclusions: Adult patients without underlying comorbidities that developed BM in recent years were older and more likely to have pneumococcal or listerial infections and systemic complications. In-hospital death was less likely in the second period, after adjusting for risk factors of mortality.

Background: Opioids are still being prescribed to manage acute postsurgical pain. Unnecessary opioid prescriptions can lead to addiction and death, as unused tablets are easily diverted.
Methods: To determine whether combination nonopioid analgesics are at least as good as opioid analgesics, a multisite, double-blind, randomized, stratified, noninferiority comparative effectiveness trial was conducted, which examined patient-centered outcomes after impacted mandibular third-molar extraction surgery.
Adjunctive PCSK9 Inhibitor Evolocumab in the Prevention of Early Neurological Deterioration in Non-cardiogenic Acute Ischemic Stroke: A Multicenter, Prospective, Randomized, Open-Label, Clinical Trial.

Background: Early neurological deterioration (END) is associated with a poor prognosis in acute ischemic stroke (AIS). Effectively lowering low-density lipoprotein cholesterol (LDL-C) can improve the stability of atherosclerotic plaque and reduce post-stroke inflammation, which may be an effective means to lower the incidence of END. The objective of this study was to determine the preventive effects of evolocumab on END in patients with non-cardiogenic AIS.

Cognitive load stimulates neural activity, essential for understanding the brain's response to stress-inducing stimuli or mental strain. This study examines the feasibility of evaluating cognitive load by extracting, selection, and classifying features from electroencephalogram (EEG) signals. We employed robust local mean decomposition (R-LMD) to decompose EEG data from each channel, recorded over a four-second period, into five modes.

Introduction: The emergence of high-efficacy disease-modifying therapies (HE DMT) for multiple sclerosis (MS) may pose challenges to the administration and monitoring burden of the therapies. This article presents the results of the Delphi consensus method to generate insights from experts on the administration and monitoring burden of HE DMT in Saudi Arabia with a special focus on cladribine.
Methods: Between January and March 2023, a two-round modified Delphi method was used to establish consensus regarding the administration and monitoring burden of HE DMTs used for MS.
Effect of intramuscular treatment with different iron dextran dosages and non-inferiority study to gleptoferron.

Background: Prevention of iron deficiency in suckling piglets by intramuscular injection of a standardized amount of iron dextran or gleptoferron in the first days of life can lead to over- or underdosage with respective health risks. Currently, combined iron products containing an active substance against coccidia are also used on farms. When using a combination product targeting two diseases, an adjustment of the necessary amount of iron to prevent anaemia in the frame of a farm-specific treatment protocol is not possible.
