The Effect of Bilateral, Two-Level Cervical Sympathetic Chain Blocks on Specific Symptom Clusters for Traumatic Brain Injury, Independent of Concomitant PTSD Symptoms.

: The aim of this study was to determine if performing ultrasound-guided, bilateral, two-level cervical sympathetic chain blocks (2LCSBs) (performed on subsequent days) improves symptoms associated with traumatic brain injury (TBI) that do not overlap with posttraumatic stress disorder (PTSD). : A retrospective chart review was conducted between August 2022 and February 2023. We identified twenty patients who received bilateral 2LCSBs for PTSD and anxiety symptoms and who also had a history of TBI.

Localized molecular chaperone synthesis maintains neuronal dendrite proteostasis.

Proteostasis is maintained through regulated protein synthesis and degradation and chaperone-assisted protein folding. However, this is challenging in neuronal projections because of their polarized morphology and constant synaptic proteome remodeling. Using high-resolution fluorescence microscopy, we discover that hippocampal and spinal cord motor neurons of mouse and human origin localize a subset of chaperone mRNAs to their dendrites and use microtubule-based transport to increase this asymmetric localization following proteotoxic stress.

Stability and agility trade-offs in spring-wing systems.

Flying insects are thought to achieve energy-efficient flapping flight by storing and releasing elastic energy in their muscles, tendons, and thorax. However, 'spring-wing' flight systems consisting of elastic elements coupled to nonlinear, unsteady aerodynamic forces present possible challenges to generating stable and responsive wing motion. The energetic efficiency from resonance in insect flight is tied to the Weis-Fogh number (), which is the ratio of peak inertial force to aerodynamic force.

Lisdexamfetamine's Efficacy in Treating Attention Deficit Hyperactivity Disorder (ADHD): A Meta-Analysis and Review.

Lisdexamfetamine dimesylate, a prodrug stimulant, appears to effectively treat Attention-Deficit/Hyperactivity Disorder (ADHD) in children and adults. However, an analysis of the treatment effects of the two subscales (inattentiveness and hyperactivity) within the ADHD Rating Scale-IV (ADHD-RS-IV) has not yet been done to determine if clinical significance may be attributed to either one. Nor has there been a meta-analysis of the individual doses of lisdexamfetamine dimesylate.

Discovery and Efficacy of AZ-PRMT5i-1, a Novel PRMT5 Inhibitor with High MTA Cooperativity.

PRMT5, a type 2 arginine methyltransferase, has a critical role in regulating cell growth and survival in cancer. With the aim of developing MTA-cooperative PRMT5 inhibitors suitable for MTAP-deficient cancers, herein we report our efforts to develop novel "MTA-cooperative" compounds identified through a high-throughput biochemical screening approach. Optimization of hits was achieved through structure-based design with a focus on improvement of oral drug-like properties.

Reversible Increased Anxiety Following Left-Sided Stellate Ganglion Block to Treat Posttraumatic Stress Disorder: A Case Report.

Describe a 2-patient case report of a rare occurrence of significantly increased anxiety after a left-sided stellate ganglion block (SGB) and the subsequent improvement of that anxiety through a right-sided SGB. Right-sided SGB to treat post-traumatic stress disorder (PTSD) has over 23 supporting publications in the peer-reviewed medical literature, including level 1 evidence. A published case series of 285 patients showed that two-level SGB may improve anxiety-related symptoms in patients.

Moth resonant mechanics are tuned to wingbeat frequency and energetic demands.

An insect's wingbeat frequency is a critical determinant of its flight performance and varies by multiple orders of magnitude across Insecta. Despite potential energetic benefits for an insect that matches its wingbeat frequency to its resonant frequency, recent work has shown that moths may operate off their resonant peak. We hypothesized that across species, wingbeat frequency scales with resonance frequency to maintain favourable energetics, but with an offset in species that use frequency modulation as a means of flight control.

The Successful Use of Bilateral 2-Level Ultrasound-Guided Stellate Ganglion Block to Improve Traumatic Brain Injury Symptoms: A Retrospective Analysis of 23 Patients.

Purpose: The purpose of the study was to determine whether performing ultrasound-guided, bilateral stellate ganglion blocks (SGBs; performed on subsequent days) improved traumatic brain injury (TBI) symptoms.

Methods: A retrospective chart review was conducted for the time period between August 2022 and February 2023 to identify patients who received bilateral, 2-level (C6 and C4) SGBs for PTSD symptoms but who also had a history of TBI. Neurobehavioral Symptoms Inventory (NSI) scores were collected at baseline, 1 week, and 1 month post-treatment in 14 males and 9 females.

Development of a Series of Pyrrolopyridone MAT2A Inhibitors.

The optimization of an allosteric fragment, discovered by differential scanning fluorimetry, to an in vivo MAT2a tool inhibitor is discussed. The structure-based drug discovery approach, aided by relative binding free energy calculations, resulted in AZ'9567 (), a potent inhibitor in vitro with excellent preclinical pharmacokinetic properties. This tool showed a selective antiproliferative effect on methylthioadenosine phosphorylase (MTAP) KO cells, both in vitro and in vivo, providing further evidence to support the utility of MAT2a inhibitors as potential anticancer therapies for MTAP-deficient tumors.

[Formula: see text] Differences between parent- and teacher-reported executive functioning behaviors after traumatic injuries.

Deficits in executive functioning (EF) behaviors are very common following pediatric traumatic brain injury (TBI) and can linger well after acute injury recovery. Raters from multiple settings provide information that may not be appreciated otherwise. We examined differences between parent and teacher ratings of EF using data examining longitudinal outcomes following pediatric TBI in comparison to orthopedic injury (OI).

Differences Between Black and White Caregivers in the Association Between Autism Diagnostic Process Satisfaction and Service Use.

Background: Black families of children with autism spectrum disorder have less access to high quality, culturally responsive care for their children.

Method: We assessed satisfaction and service utilization among fifty (29%) Black caregivers and 124 (71%) White caregivers of children with autism spectrum disorder. We also examined whether race moderated the association between satisfaction and service utilization.

Diagnostic suspicion bias and machine learning: Breaking the awareness deadlock for sepsis detection.

Many early warning algorithms are downstream of clinical evaluation and diagnostic testing, which means that they may not be useful when clinicians fail to suspect illness and fail to order appropriate tests. Depending on how such algorithms handle missing data, they could even indicate "low risk" simply because the testing data were never ordered. We considered predictive methodologies to identify sepsis at triage, before diagnostic tests are ordered, in a busy Emergency Department (ED).

Localized synthesis of molecular chaperones sustains neuronal proteostasis.

Neurons are challenged to maintain proteostasis in neuronal projections, particularly with the physiological stress at synapses to support intercellular communication underlying important functions such as memory and movement control. Proteostasis is maintained through regulated protein synthesis and degradation and chaperone-assisted protein folding. Using high-resolution fluorescent microscopy, we discovered that neurons localize a subset of chaperone mRNAs to their dendrites, particularly more proximal regions, and increase this asymmetric localization following proteotoxic stress through microtubule-based transport from the soma.

Examining bidirectional associations between sleep and behavior among children with attention-deficit/hyperactivity disorder.

Background: Children with attention-deficit/hyperactivity disorder (ADHD) have more sleep problems than their peers which contribute to behavioral and functional impairments. This study examines the bidirectional relationship between nightly sleep (i.e.
