Relationship Among Sleep Disturbance, Stress, And Suicidal Ideation In Clinical High Risk For Psychosis, Heather M Wastler, Daniel Mamah, Et Al.

2020-Current year OA Pubs

BACKGROUND AND HYPOTHESIS: Sleep disturbance is a well-established risk factor for suicide, though few studies to date have examined whether sleep disturbance contributes to suicide risk among individuals at clinical high risk for psychosis (CHR). The current study addressed this gap in the literature. We hypothesized that sleep disturbance would have a unique relationship with suicidal ideation/attempts when accounting for other variables in the model. We also hypothesized that the interaction between sleep disturbance/attenuated positive symptoms and sleep disturbance/stress would be related to suicidal ideation/attempts in CHR.

STUDY DESIGN: The current study used data generated by the Accelerating Medicines Partnership® …

Immortalization And Characterization Of Schwann Cell Lines Derived From Nf1-Associated Cutaneous Neurofibromas, Hua Li, Angela Hirbe, Et Al.

2020-Current year OA Pubs

Neurofibromatosis type 1 (NF1) is an autosomal dominant condition in which patients are heterozygous for a disruptive pathogenic variant in the NF1 gene. The most characteristic feature of the condition NF1 is the neurofibroma, a benign, multi-cellular tumor which initiates when a cell of the Schwann cell lineage gains a somatic pathogenic variant of the other NF1 allele. Neurofibromas developing at nerve termini in the skin are termed "cutaneous" neurofibromas (cNFs), while those developing within larger nerves are termed "plexiform." Most patients develop cNFs beginning in late childhood or early adulthood, continuing throughout life at variable rates. Some patients may …

2020-Current year OA Pubs

A growing body of literature describes the anti-inflammatory, neuroprotective, and anti-epileptic properties of the cannabis sativa constituent cannabidiol, suggesting that it might play a useful role in the treatment of neurodegenerative diseases. Late infantile neuronal ceroid lipofuscinosis (CLN2 disease) is a rare pediatric neurodegenerative disorder resulting from an inherited dysfunction of the lysosome. CLN2 disease, and its representative animal models, display neuroimmune response, neuroinflammation, neurodegeneration, and epileptic seizures, and these symptoms are all touted as potential targets of cannabidiol therapeutic benefit. Here, we treated a valid model of CLN2 disease with long-term daily cannabidiol (300 mg/kg) from 1 month of …

Does In-Bed Cycling Delivered Within 48 Hours Of Mechanical Ventilation, Reduce The Occurrence Of Delirium In Critically Ill Patients: A Mixed-Methods Feasibility Randomised Controlled Trial Protocol, Jacqueline Bennion, Mark Hudson, Mary Hickson, Victoria Allgar, Bridie Kent, David Mcwilliams, Daniel Martin

Peninsula Medical School

Background: Delirium is a severe neuropsychiatric clinical state presenting as an acute onset of cognitive deficits. Patients receiving invasive mechanical ventilation (IMV), have the highest incidence (50%–80%) of delirium amongst patients admitted to intensive care units. Preliminary data indicates that early mobilisation is associated with reduced delirium in critically ill patients. However, definitive evidence is lacking. Current practice varies due to many barriers to patients, who require IMV, receiving early mobilisation interventions. In-bed cycling may address some of these barriers. This research aims to evaluate the feasibility and acceptability of early in-bed cycling to reduce delirium in critically ill patients. …

Fault Tolerant Adaptive Control Under Actuator Saturation For Robot Manipulators, D. J. López-Araujo, N. Alvarez-Jarquin, P. Borja, A. T. Becker

School of Engineering, Computing and Mathematics

In practice, actuators inherently have natural limitations that are often overlooked by theoretical control strategies, such as bounded output and discrepancies between calculated and actual responses. Consequently, reliable control techniques must be employed to ensure safe and dependable operation. We propose an adaptive control law for global regulation in the case of partial loss of effectiveness due to input faults. The proposed control strategy maintains the system at the desired configuration while accounting for the physical limitations of the actuators. Additionally, it is suitable for dealing with unknown parameters in the vector of gravitational forces, making it robust to these …
