The brain's sensitivity to sensory error can be modulated by altering perceived variability.

When individuals make a movement that produces an unexpected outcome, they learn from the resulting error. This process, essential in both acquiring new motor skills and adapting to changing environments, critically relies on error sensitivity, which governs how much behavioral change results from a given error. Although behavioral and computational evidence suggests error sensitivity can change in response to task demands, neural evidence regarding the flexibility of error sensitivity in the human brain is lacking.

Fecal microbial transplants as investigative tools in cancer.

The gut microbiome plays a critical role in the development, progression, and treatment of cancer. As interest in microbiome-immune-cancer interactions expands, the prevalence of fecal microbial transplant (FMT) models has increased proportionally. However, current literature does not provide adequate details or consistent approaches to allow for necessary rigor and experimental reproducibility.

Standardized Temporary Atrial Epicardial Wire Locations Lead to Enhanced Atrial Signal Identification.

Arrhythmias, common after pediatric cardiac surgery, are associated with increased morbidity and mortality. Atrial epicardial wires (AEW) improve diagnostic accuracy but have variable pacing and sensing properties based on their location. Even so, there are no longitudinal prospective pediatric studies examining ideal placement of AEW.

Twice-Yearly Depemokimab in Severe Asthma with an Eosinophilic Phenotype.

Background: Depemokimab is an ultra-long-acting biologic therapy with enhanced binding affinity for interleukin-5 that may enable effective 6-month dosing intervals.

Methods: In these phase 3A, randomized, placebo-controlled replicate trials, we evaluated the efficacy and safety of depemokimab in patients with severe asthma and an eosinophilic phenotype characterized by a high eosinophil count (≥300 cells per microliter in the previous 12 months or ≥150 cells per microliter at screening) and a history of exacerbations despite the receipt of medium- or high-dose inhaled glucocorticoids. Patients were randomly assigned in a 2:1 ratio to receive either depemokimab (at a dose of 100 mg subcutaneously) or placebo at weeks 0 and 26, plus standard care.

Preoperative Hypoalbuminemia is Associated With Higher 30-day Mortality and Complications After Esophagectomy.

Background: Serum albumin level is routinely screened during preoperative assessments as a biomarker for poor nutritional status and/or concurrent inflammation. In esophagectomy, while early postoperative hypoalbuminemia is associated with a higher risk of adverse surgical outcomes, the effects of preoperative hypoalbuminemia on esophagectomy outcomes were conflicting. This study aimed to examine the effect of preoperative hypoalbuminemia on 30-day outcomes following esophagectomy.

The Ruminant Telomere-to-Telomere (RT2T) Consortium.

Telomere-to-telomere (T2T) assemblies reveal new insights into the structure and function of the previously 'invisible' parts of the genome and allow comparative analyses of complete genomes across entire clades. We present here an open collaborative effort, termed the 'Ruminant T2T Consortium' (RT2T), that aims to generate complete diploid assemblies for numerous species of the Artiodactyla suborder Ruminantia to examine chromosomal evolution in the context of natural selection and domestication of species used as livestock.

Feasibility and acceptability of studying full-time nurse faculty salaries.

Background: The nursing shortage is driven, in part, by the critical shortage of nursing faculty. Consequently, qualified potential nursing students are being turned away from nursing schools each year. The preeminent issue influencing the United States nurse faculty workforce shortage is salary; financial compensation is higher in clinical and private-sector settings than educational settings.

How Should Harm Reduction Be Included in Care Continua for Patients With Opioid Use Disorder?

Practices and interventions that aim to slow progression or reduce negative consequences of substance use are harm reduction strategies. Often described as a form of tertiary prevention, harm reduction is key to caring well for people who use drugs. Evidence-based harm reduction interventions include naloxone and syringe service programs.

Theta-burst stimulation over primary somatosensory cortex modulates tactile acuity of tongue.

Background: Emerging studies in humans have established the modulatory effects of repetitive transcranial magnetic stimulation (rTMS) over primary somatosensory cortex (S1) on somatosensory cortex activity and perception. However, to date, research in this area has primarily focused on the hand and fingers, leaving a gap in our understanding of the modulatory effects of rTMS on somatosensory perception of the orofacial system and speech articulators.

Objective: The present study aimed to examine the effects of different types of theta-burst stimulation-continuous TBS (cTBS), intermittent TBS (iTBS), or sham-over the tongue representation of left S1 on tactile acuity of the tongue.

Pars Opercularis Underlies Efferent Predictions and Successful Auditory Feedback Processing in Speech: Evidence From Left-Hemisphere Stroke.

Hearing one's own speech allows for acoustic self-monitoring in real time. Left-hemisphere motor planning regions are thought to give rise to efferent predictions that can be compared to true feedback in sensory cortices, resulting in neural suppression commensurate with the degree of overlap between predicted and actual sensations. Sensory prediction errors thus serve as a possible mechanism of detection of deviant speech sounds, which can then feed back into corrective action, allowing for online control of speech acoustics.

Attitudes towards surgical safety checklists among American College of Veterinary Surgeons diplomates.

Objective: To examine attitudes towards surgical safety checklists (SSCs) among American College of Veterinary Surgeons (ACVS) diplomates and to identify barriers to implementation.

Study Design: Qualitative online research survey.

Sample Population: A total of 1282 current ACVS diplomates.

Heterogeneous Graph Convolutional Neural Network via Hodge-Laplacian for Brain Functional Data.

This study proposes a novel heterogeneous graph convolutional neural network (HGCNN) to handle complex brain fMRI data at regional and across-region levels. We introduce a generic formulation of spectral filters on heterogeneous graphs by introducing the - Hodge-Laplacian (HL) operator. In particular, we propose Laguerre polynomial approximations of HL spectral filters and prove that their spatial localization on graphs is related to the polynomial order.

Judgment by nursing leaders is the wrong response.

Exploring the Impact of Active Site Structure on the Conversion of Methane to Methanol in Cu-Exchanged Zeolites.

In the past, Cu-oxo or -hydroxy clusters hosted in zeolites have been suggested to enable the selective conversion of methane to methanol, but the impact of the active site's stoichiometry and structure on methanol production is still poorly understood. Herein, we apply theoretical modeling in conjunction with experiments to study the impact of these two factors on partial methane oxidation in the Cu-exchanged zeolite SSZ-13. Phase diagrams developed from first-principles suggest that Cu-hydroxy or Cu-oxo dimers are stabilized when O or NO are used to activate the catalyst, respectively.
