Do inhibitory interneurons encode information or just keep the rhythm?

Inhibitory interneurons may help encode the brain's internal representation of space.

Shared and distinct alterations in brain structure of youth with internalizing or externalizing disorders: Findings from the ENIGMA Antisocial Behavior, ADHD, MDD, and Anxiety Working Groups.

Background: Externalizing and internalizing disorders are common in youth but are often studied separately, preventing researchers from identifying shared (i.e., transdiagnostic) alterations in brain structure.

Multidimensional biocircuitry of exercise adaptation: integrating in vivo and ex vivo phenomics with miRNA mapping.

In a randomized, dose-response trial, we used molecular and phenomic profiling to compare responses with traditional moderate-intensity endurance and resistance training (TRAD) versus high-intensity tactical training (HITT) that encompassed explosive whole-body interval training and high-intensity resistance training. Ninety-four participants (18-27 yr) completed 12 wk of TRAD or HITT followed by 4 wk of detraining. Although similar performance and body composition improvements were observed in response to HITT and TRAD, some dose-dependent differences were observed for: ) ex vivo muscle tissue changes in myofiber size, capillarization, satellite cell frequency, and mitochondrial function and ) differential gene expression (DGE) of muscle and serum exosomal miRNAs (miRs).

Cross-Continental Analysis Shows That Disturbance Effects on Reptile Body Condition Do Not Predict Abundance Responses.

Ecological disturbances are discrete events that alter or transform the physical, chemical, or biological characteristics of ecosystems. Disturbance can cause animal populations to decline and, according to the risk-disturbance hypothesis and population collapse framework, these declines can be predicted by declines in animal body condition. However, no research has empirically examined the general relationship between body condition and abundance, nor their relationship in response to disturbance.

Cross-sectoral trade-offs in a changing climate: Surrogate models to balance home energy bills, occupant comfort, and power system externalities.

Electrifying buildings using heat pumps may exacerbate the trade-offs between the sometimes-conflicting objectives of building occupants, power systems, and society. To navigate these, we develop a modeling framework that rapidly co-optimizes home energy bills, indoor temperatures, power system air pollution externalities, and peak demand costs. We demonstrate this framework for 17,000 representative single-family homes across 54 U.

Successful Evidence-Based Parenting Programs are Associated With Brain Changes and Improved Reward Processing in Boys With Conduct Problems.

Background: Early parenting interventions are the gold standard treatment for reducing antisocial behaviour (ASB) in children with conduct problems (CP), but the neurocognitive mechanisms underpinning treatment response are unknown.

Methods: We assessed fMRI and performance data from a reward learning task in boys with CP (aged 5-10 years old) before and after gold-standard group parenting intervention. Matched controls were assessed concurrently at two equally spaced time points.

Assessing the effect of musical experience on cognitive function in older age: a coordinated analysis.

Current evidence suggests that older adults with musical experience demonstrate better cognitive functioning than those without. However, this difference is poorly characterized, and findings are mixed, possibly due to variations in definitions of musical experience, cognitive measurements, and analytical approaches. To address this, the current study used a coordinated analysis approach to investigate whether there were differences in performance in certain cognitive domains between older adults with musical experience and those without.

Penetrance of Neurodevelopmental Copy Number Variants Is Associated With Variations in Cortical Morphology.

Background: Copy number variants (CNVs) may increase the risk for neurodevelopmental conditions. The neurobiological mechanisms that link these high-risk genetic variants to clinical phenotypes are largely unknown. An important question is whether brain abnormalities in individuals who carry CNVs are associated with their degree of penetrance.

Intranasal oxytocin modulates brain activity during emotional processing in children with treatment resistant conduct problems.

One of the most highly replicated neural correlates of Conduct Problems (CP) is amygdala hypoactivity to another person's fear. We recently reported that this correlate was only observed in boys with persistent CP (i.e.

Antimicrobial-Resistant Infections in Hospitalized Patients.

Importance: Antimicrobial resistance is a major public health problem in the US. Estimating national rates of antimicrobial-resistant infections commonly associated with health care can aid in targeted public health efforts.

Objective: To determine the national incidence rates of 6 pathogens over time: methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus spp (VRE), extended-spectrum cephalosporin-resistant Escherichia coli and Klebsiella spp (excluding Klebsiella aerogenes) (ESCR-EK), carbapenem-resistant Enterobacterales (CRE), carbapenem-resistant Acinetobacter spp (CRAsp), and multidrug-resistant (MDR) Pseudomonas aeruginosa.

Spinal cord demyelination predicts neurological deterioration in patients with mild degenerative cervical myelopathy.

Background: Degenerative cervical myelopathy (DCM) is the most common form of atraumatic spinal cord injury globally. Clinical guidelines regarding surgery for patients with mild DCM and minimal symptoms remain uncertain. This study aims to identify imaging and clinical predictors of neurological deterioration in mild DCM and explore pathophysiological correlates to guide clinical decision-making.

Disentangling the neural underpinnings of response inhibition in disruptive behavior and co-occurring ADHD.

While impaired response inhibition has been reported in attention-deficit/hyperactivity disorder (ADHD), findings in disruptive behavior disorders (DBDs) have been inconsistent, probably due to unaccounted effects of co-occurring ADHD in DBD. This study investigated the associations of behavioral and neural correlates of response inhibition with DBD and ADHD symptom severity, covarying for each other in a dimensional approach. Functional magnetic resonance imaging data were available for 35 children and adolescents with DBDs (8-18 years old, 19 males), and 31 age-matched unaffected controls (18 males) while performing a performance-adjusted stop-signal task.

Long-term effectiveness and feasibility of CT-guided cryoablation as a novel treatment option for symptomatic lumbar synovial cysts.

Objective: To present a case series with a long-term follow-up of CT-guided cryoablation procedure for the minimally invasive treatment of symptomatic lumbar facet synovial cyst with a mean follow-up of 38 months (range, 15-55).

Materials And Methods: We present a retrospective, uncontrolled clinical case series in a single institution on patients treated with CT-guided cryoablation for symptomatic lumbar facet joint synovial cyst refractory to or not suitable for imaging-guided rupture procedure. In two cases, patients underwent cryoablation and cyst rupture within a 2-week period.

Higher intensity exercise after encoding is more conducive to episodic memory retention than lower intensity exercise: A field study in endurance runners.

An acute bout of exercise in the moments after learning benefits the retention of new memories. This finding can be explained, at least partly, through a consolidation account: exercise provides a physiological state that is conducive to the early stabilisation of labile new memories, which supports their retention and subsequent retrieval. The modification of consolidation through non-invasive exercise interventions offers great applied potential.

Neuropsychological performance in women at risk of postpartum depression and postpartum psychosis.

Purpose: While neuropsychological deficits are commonly observed in affective and psychotic disorders, this remains unexplored in these disorders when they occur during pregnancy and the postpartum period.

Methods: A neuropsychological test battery was administered to women defined at risk of postpartum depression (PD, N = 53) because having either a current or past diagnosis of major depressive disorder, women at risk of postpartum psychosis (PP, N = 43) because of a diagnosis of bipolar disorder or schizoaffective disorder and/or a previous episode of PP and women not at risk (NR, N = 48) in the third trimester of pregnancy. Generalized and specific cognitive abilities were compared between groups.

Animations to communicate public health prevention messages: a realist review protocol.

Introduction: With digital and social media advances, animated health communications (health animations) are highly prevalent globally, yet the evidence base underpinning them remains unclear and limited. While individual studies have attempted to explore the effectiveness, acceptability and usability of specific features of health animations, there is substantial heterogeneity in study design, comparators and the animation design and content. Consequently, there is a need to synthesise evidence of health animations using an approach that recognises this contextual complexity, which may affect their impact.

A synergistic workspace for human consciousness revealed by Integrated Information Decomposition.

How is the information-processing architecture of the human brain organised, and how does its organisation support consciousness? Here, we combine network science and a rigorous information-theoretic notion of synergy to delineate a 'synergistic global workspace', comprising gateway regions that gather synergistic information from specialised modules across the human brain. This information is then integrated within the workspace and widely distributed via broadcaster regions. Through functional MRI analysis, we show that gateway regions of the synergistic workspace correspond to the human brain's default mode network, whereas broadcasters coincide with the executive control network.

Muscle-derived microRNAs correlated with thigh lean mass gains during progressive resistance training in older adults.

Resistance training (RT) remains the most effective treatment for age-related declines in muscle mass. However, many older adults experience attenuated muscle hypertrophy in response to RT when compared with younger adults. This may be attributed to underlying molecular processes that are dysregulated by aging and exacerbated by improperly prescribed RT weekly volume, intensity, and/or frequency doses.

Mechanisms and implications of gamma oscillation plasticity.

A recent study by Hadler and colleagues uncovered a novel form of plasticity of gamma oscillations in an ex vivo hippocampal slice preparation which they term 'gamma potentiation'. We discuss the potential cellular mechanisms of this form of plasticity and its functional and translational implications.

Weight Loss Success With Repeat Intragastric Balloon Placement After Hyperinflation and Removal of the Index Balloon.

Intragastric balloons are an increasingly common endoscopic alternative to bariatric surgery for the treatment of obesity. Hyperinflation is a rare complication that presents as acute-onset epigastric pain, nausea, vomiting, early satiety, abdominal distention or bloating, and rapid weight loss. Hyperinflation requires prompt diagnosis and removal of the balloon to prevent complications including gastric outlet obstruction or gastric perforation.

Post-encoding task engagement not attentional load is detrimental to awake consolidation.

The fate of new memories depends partly on the cognitive state experienced immediately following encoding. Wakeful rest, relative to task engagement, benefits retention and this effect is typically explained through a consolidation account: rest is theorised to provide a state of minimal interference, which would otherwise disrupt consolidation. Yet, the determinants of consolidation interference, notably the contribution of attention, remain poorly characterised.

Real-World Molecular Out-Of-Distribution: Specification and Investigation.

This study presents a rigorous framework for investigating molecular out-of-distribution (MOOD) generalization in drug discovery. The concept of MOOD is first clarified through a that demonstrates how the covariate shifts encountered during real-world deployment can be characterized by the distribution of sample distances to the training set. We find that these shifts can cause performance to drop by up to 60% and uncertainty calibration by up to 40%.
