A Real-World Prospective Multiple Sclerosis Pregnancy Registry in the United States: PREG-MS.

Background And Objectives: Multiple sclerosis (MS) affects more than 1 million people in the United States, including reproductive-age women. There has been a paucity of prospective, pregnancy registries based on MS disease rather than medication exposures. A prospective MS pregnancy registry (PREG-MS) was established in 2017 as a prospective, single-cohort, real-world MS pregnancy registry in New England States of the United States, with goals to evaluate (1) course of MS and disease-modifying therapies (DMT) use during conception attempts and in the peripartum period, (2) pregnancy outcomes in women with MS (WwMS), and (3) longer-term developmental outcomes in offspring of WwMS.

Genomic virulence markers are associated with severe outcomes in patients with Pseudomonas aeruginosa bloodstream infection.

Background: Pseudomonas aeruginosa (PA) bloodstream infection (BSI) is a common healthcare-associated complication linked to antimicrobial resistance and high mortality. Ongoing clinical trials are exploring novel anti-virulence agents, yet studies on how bacterial virulence affects PA infection outcomes is conflicting and data from real-world clinical populations is limited.

Methods: We studied a multicentre cohort of 773 adult patients with PA BSI consecutively collected during 7-years from sites in Europe and Australia.

On the profinite rigidity of free and surface groups.

Let be either a free group or the fundamental group of a closed hyperbolic surface. We show that if is a finitely generated residually- group with the same pro- completion as , then two-generated subgroups of are free. This generalises (and gives a new proof of) the analogous result of Baumslag for parafree groups.

Native arbuscular mycorrhizal fungi drive ecophysiology through phenotypic integration and functional plasticity under the Sonoran desert conditions.

Knowledge is scarce to what extent environmental drivers and native symbiotic fungi in soil induce abrupt (short-term), systemic (multiple traits), or specific (a subset of traits) shifts in C plants' ecophysiological/mycorrhizal responses. We cultivated an emblematic native C species (Capsicum annuum var. glabriusculum, "Chiltepín") to look at how the extreme heat of the Sonoran desert, sunlight regimes (low = 2, intermediate = 15, high = 46 mol m d) and density of native arbuscular mycorrhizal fungi in soil (low AMF = 1% v/v, high AMF = 100% v/v), drive shifts on mycorrhizal responses through multiple functional traits (106 traits).

Optogenetic hedonic hotspots in orbitofrontal cortex and insula: causing enhancement of sweetness 'liking'.

Hedonic hotspots are brain subregions that causally amplify the hedonic impact of palatable tastes, measured as increases in affective orofacial 'liking' reactions to sweetness. Previously, two cortical hedonic hotspots in orbitofrontal cortex and insula were identified by neurochemical stimulation using opioid or orexin microinjections. Here we used optogenetic stimulation in rats as an independent neurobiological technique for activating cortical hedonic hotspots to identify hedonic functions and map boundaries.

Risk management during times of health uncertainty in Spain: A qualitative analysis of ethical challenges.

The study examines the reflections of various experts in risk management when asked about uncertainty generated by a health threat and the response to such a threat: what criteria should guide action when potential harm is anticipated, but not known with certainty? The objective of the research is to obtain a holistic perspective of ethical conflicts in risk management, based on experts' accounts within the Spanish territory. A qualitative study was conducted through semi-structured interviews with 27 experts from various fields related to health risk management and its ethical implications, following the grounded theory method. The method includes theory generation through an inductive approach, based on the identified categories.

High-resolution mapping of urban Aedes aegypti immature abundance through breeding site detection based on satellite and street view imagery.

Identification of Aedes aegypti breeding hotspots is essential for the implementation of targeted vector control strategies and thus the prevention of several mosquito-borne diseases worldwide. Training computer vision models on satellite and street view imagery in the municipality of Rio de Janeiro, we analyzed the correlation between the density of common breeding grounds and Aedes aegypti infestation measured by ovitraps on a monthly basis between 2019 and 2022. Our findings emphasized the significance (p ≤ 0.

ATP-P2X7R pathway activation limits the Tfh cell compartment during pediatric RSV infection.

Background: Follicular helper T cells (Tfh) are pivotal in B cell responses. Activation of the purinergic receptor P2X7 on Tfh cells regulates their activity. We investigated the ATP-P2X7R axis in circulating Tfh (cTfh) cells during Respiratory Syncytial Virus (RSV) infection.

Associations Between Neighborhood Resources and Youths' Response to Reward Omission in a Task Modeling Negatively Biased Environments.

Objective: Neighborhoods provide essential resources (eg, education, safe housing, green space) that influence neurodevelopment and mental health. However, we need a clearer understanding of the mechanisms mediating these relationships. Limited access to neighborhood resources may hinder youths from achieving their goals and, over time, shape their behavioral and neurobiological response to negatively biased environments blocking goals and rewards.

Multivariate Assessment of Inhibitory Control in Youth: Links With Psychopathology and Brain Function.

Inhibitory control is central to many theories of cognitive and brain development, and impairments in inhibitory control are posited to underlie developmental psychopathology. In this study, we tested the possibility of shared versus unique associations between inhibitory control and three common symptom dimensions in youth psychopathology: attention-deficit/hyperactivity disorder (ADHD), anxiety, and irritability. We quantified inhibitory control using four different experimental tasks to estimate a latent variable in 246 youth (8-18 years old) with varying symptom types and levels.

Comparing anti-tumor and anti-self immunity in a patient with melanoma receiving immune checkpoint blockade.

Background: Tumor regression following immune checkpoint blockade (ICB) is often associated with immune-related adverse events (irAEs), marked by inflammation in non-cancerous tissues. This study was undertaken to investigate the functional relationship between anti-tumor and anti-self immunity, to facilitate irAE management while promoting anti-tumor immunity.

Methods: Multiple biopsies from tumor and inflamed tissues were collected from a patient with melanoma experiencing both tumor regression and irAEs on ICB, who underwent rapid autopsy.

Magnetic aerogels from FePt and CoPt directly from organic solution.

Here the synthesis of magnetic aerogels from iron platinum and cobalt platinum nanoparticles is presented. The use of hydrazine monohydrate as destabilizing agent triggers the gelation directly from organic solution, and therefore a phase transfer to aqueous media prior to the gelation is not necessary. The aerogels were characterized through Transmission Electron Microscopy, Scanning Electron Microscopy, Powder X-Ray Diffraction Analysis and Argon Physisorption measurements to prove the formation of a porous network and define their compositions.

Ketamine in the treatment of refractory and super-refractory status epilepticus: Experience from two centres.

Purpose: There is insufficient evidence on the management of refractory status epilepticus (RSE) and super-RSE (SRSE). Ketamine is a N-methyl-d-aspartate receptor antagonist in the treatment of these entities. Our objectives were to study the effectiveness and safety of ketamine in the treatment of adult patients with RSE and SRSE, to determine the factors that can influence the response to ketamine, and to explore its use in patients without mechanical ventilation.

A new species and updates on the Rhagovelia angustipes complex (Hemiptera, Heteroptera, Veliidae) in Colombia.

Rhagovelia Mayr, 1865 (Hemiptera, Heteroptera, Veliidae) is a diverse genus of small to medium-sized true bugs that live on the surface of the water, preferentially in lotic environments with moderate to strong current. The Rhagovelia angustipes species complex is particularly speciose in Colombia, and has recently been the subject of a revision. Nonetheless, new species of the complex are still being discovered in the country.
