Kearns-Sayre syndrome (KSS) is a mitochondrial encephalopathic disorder. Because mitochondria are ubiquitous organelles that are present in almost every human tissue, their dysfunction can affect nearly any organ system and give rise to a wide range of clinical characteristics. 1: As is the case with most diseases associated with mitochondrial DNA (mtDNA) mutations, the clinical features of KSS were defined before modern molecular genetic classifications emerged. 2: The exact prevalence of KSS is unknown; however, estimates place it at about 1:100,000 people. Although it is a rather rare syndrome, the ability to recognize or consider KSS as part of a …

Acute Necrotizing Encephalopathy In An Infant: A Case Report, Elisamia Ngowi, Zeenat Juneja, Jacqueline Gabone, Maria Bulimba, Mohamedraza Ebrahim, Yaser Abdallah
Paediatrics and Child Health, East Africa
Background: Acute necrotizing encephalopathy is a rare, severe neurological condition, characterized by symmetrical necrotic brain lesions affecting the thalamus, cerebral white matter, brain stem, and cerebellum. Diagnosis relies on characteristic clinical and radiological features.
Methodology: We describe a 10-month-old female infant presenting with multiple seizures following a brief febrile upper respiratory illness.
Findings: MRI of the brain showed bilateral symmetrical abnormal signal intensities involving both thalami and caudate nucleus, consistent with ANE. Management of ANE is symptom-related but high-dose steroids and IVIG have been used.
Conclusion: This case highlights the importance of recognizing ANE beyond its …

Unfractionated heparin (UFH) and low molecular weight heparin (LMWH) are often administered to prevent venous thromboembolism (VTE) in critically ill patients. However, the preferred prophylactic agent (UFH or LMWH) is not known. We compared the all-cause mortality rate in patients receiving UFH to LMWH for VTE prophylaxis. We conducted a retrospective propensity score adjusted analysis of patients admitted to neuro-critical, surgical, or medical intensive care units. Patients were included if they were screened with venous duplex ultrasonography or computed tomography angiography for detection of VTE. The primary outcome was all-cause mortality. Secondary outcomes included the prevalence of VTE, deep vein …

Temporal lobe epilepsy (TLE) often courses with cognitive deficits, but its underlying neuronal basis remains unclear. Confluent data suggest that epilepsy share pathophysiological mechanisms with neurodegenerative diseases. However, as most studies analyze subjects 60 years old and older, it is challenging to rule out that neurodegenerative changes arise from age-related mechanisms rather than epilepsy in these individuals. To fill this gap, we conducted a neuropathological investigation of the hippocampal formation of 22 adults with mesial TLE and 20 age- and sex-matched controls (both younger than 60 years). Moreover, we interrogated the relationship between these neuropathological metrics and cognitive performance. Hippocampal …
Regeneration Of Neurons In Human Brain Tissue; A Revolutionary Concept With Therapeutic Potential, Mackenzie R. Dunn
Regeneration Of Neurons In Human Brain Tissue; A Revolutionary Concept With Therapeutic Potential, Mackenzie R. Dunn
Biomedical Sciences Undergraduate Research
There is current research to suggest that endogenous neuronal regeneration, exogenous neuronal stem cell transplantation and glial cell reprogramming could be prospective therapeutic treatments for neurodegeneration and traumatic injury. With these conditions, there is significant brain atrophy, loss of neurons and loss of synaptic connections which can have devastating effects on executive functioning, cognition, learning and memory. This review will examine these modern approaches to adult neurogenesis, and assess the viable mechanisms and future outlook of these three therapies for neurological regenerative medicine.

BACKGROUND: Peripheral nerve stimulation (PNS) is an effective neuromodulation therapy for chronic neuropathic and nociceptive pain. Although the total number of PNS implantations has increased over the last decade, no curriculum exists to guide training and learning of this therapy. The goal of the North American Neuromodulation Society (NANS) education committee is to develop a series of competency-based curriculums for neuromodulation therapies. The PNS curriculum is the latest part of such series, following the curriculums for spinal cord stimulation and intrathecal drug delivery system.
MATERIALS AND METHODS: A multidisciplinary task force (anesthesiology, physical medicine and rehabilitation, neurosurgery, preventive medicine and …

Ambulatory and Primary Care Articles
Ethyl chloride is a common topical anesthetic. However, when abused as an inhalant, effects can range from headaches and dizziness to debilitating neurotoxicity requiring intubation. While previous case reports describe the short-term reversible neurotoxicity of ethyl chloride, ours show chronic morbidity and mortality outcome. During the initial evaluation, it is essential to consider the rising trend of commercially available inhalants being used as recreational drugs. We present a case of a middle-aged man presenting with subacute neurotoxicity due to repeated abuse of ethyl chloride.
Refugees Living With Dementia: Assessing The Barriers To Healthcare Access In Crisis-Affected Populations In Lebanon And Switzerland, And The Role Humanitarian Actors Have On Addressing Them, Pedro Gomez
Independent Study Project (ISP) Collection
As life expectancies increase in many places around the world, the prevalence of aging populations has increased. Consequently, increased numbers of people globally, especially in developing countries, have been diagnosed with conditions associated with old age. Dementia, a group of conditions associated with impaired cognitive functions, is among these. Notwithstanding, many developing countries have done poorly with regards to diagnosing and treating dementia, with some cultures not even having a word to describe the condition. (ADI 2022). The lack of a diagnosis and knowledge about dementia for some refugee communities has led to healthcare challenges in their host countries (Corfield …

Medical imaging deep learning models are often large and complex, requiring specialized hardware to train and evaluate these models. To address such issues, we propose the PocketNet paradigm to reduce the size of deep learning models by throttling the growth of the number of channels in convolutional neural networks. We demonstrate that, for a range of segmentation and classification tasks, PocketNet architectures produce results comparable to that of conventional neural networks while reducing the number of parameters by multiple orders of magnitude, using up to 90% less GPU memory, and speeding up training times by up to 40%, thereby allowing …

Misfolded alpha-synuclein (αSyn) aggregates are a hallmark event in Parkinson’s disease (PD) and other synucleinopathies. Recently, αSyn seed amplification assays (αSyn-SAAs) have shown promise as a test for biochemical diagnosis of synucleinopathies. αSyn-SAAs use the intrinsic self-replicative nature of misfolded αSyn aggregates (seeds) to multiply them in vitro. In these assays, αSyn seeds circulating in biological fluids are amplified by a cyclical process that includes aggregate fragmentation into smaller self-propagating seeds, followed by elongation at the expense of recombinant αSyn (rec-αSyn). Amplification of the seeds allows detection by fluorescent dyes specific for amyloids, such as thioflavin T. Several αSyn-SAA reports …

The emergence of a novel class of infectious agent composed exclusively of a misfolded protein (termed prions) has been a challenge in modern biomedicine. Despite similarities on the behavior of prions with respect to conventional pathogens, the many uncertainties regarding the biology and virulence of prions make them a worrisome paradigm. Since prions do not contain nucleic acids and rely on a very different way of replication and spreading, it was necessary to invent a novel technology to study them. In this article, we provide an overview of such a technology, termed protein misfolding cyclic amplification (PMCA), and summarize its …

Traditional deep brain stimulation (DBS) treatment for Parkinson's disease (PD) targets the placement of DBS leads into subthalamic nucleus (STN). Extraction of neurobiomarkers from STN local field potential activity can be used for the optimization of DBS. Beta (12-30 Hz) and high frequency oscillations (200-450 Hz, HFO) of STN and their phase-amplitude coupling have been previously correlated with symptom severity in PD. The typical approach is to take bipolar derivations of electrode contacts in order to enhance recordings of local brain activity and suppress noise levels. This approach can often cancel the signals in correlated neighboring contacts and create ambiguity …

INTRODUCTION: Deep brain stimulation (DBS) is an effective treatment for Parkinson's disease (PD), but its efficacy is tied to DBS programming, which is often time consuming and burdensome for patients, caregivers, and clinicians. Our aim is to test whether the Mobile Application for PD DBS (MAP DBS), a clinical decision support system, can improve programming.
METHODS: We conducted an open-label, 1:1 randomized, controlled, multicenter clinical trial comparing six months of SOC standard of care (SOC) to six months of MAP DBS-aided programming. We enrolled patients between 30 and 80 years old who received DBS to treat idiopathic PD at six …

The processing of visual information for collision avoidance has been investigated at the biophysical level in several model systems. In grasshoppers, the (so-called) [Formula: see text] model captures reasonably well the visual processing performed by an identified neuron called the lobular giant movement detector as it tracks approaching objects. Similar phenomenological models have been used to describe either the firing rate or the membrane potential of neurons responsible for visually guided collision avoidance in other animals. Specifically, in goldfish, the [Formula: see text] model has been proposed to describe the Mauthner cell, an identified neuron involved in startle escape responses. …

Phage Peptide Technology To Characterize Extracellular Vesicles In The Brain Tumors, Jadelynn Rudolf
Undergraduate Research Conference
Extracellular vesicles (EV) are lipid-bound containers derived from the endosomal membrane network or from the extracellular membrane of cells. They can carry proteins, lipids, miRNAs, and other molecules, and may be involved in intercellular communication via membrane-associated proteins. Glioblastomas (GBM) are aggressive cancers of the brain and spinal cord derived from astrocytes. Extracellular vesicles derived from glioblastomas can make their way through the blood brain barrier and find their way to different bodily fluids, and so could serve as biomarkers for this cancer. We have isolated phage-display peptides from a commercial library of random phage-displayed peptides that will bind glioblastoma …

Fifty years ago, Clark and Euler published a model of the neural control of respiration that stimulated modern studies on the central generator of the rate and depth of breathing. These studies led to new discoveries concerning both anatomical localization and functional characteristics of respiratory central pattern generator (CPG), and as a result our knowledge has greatly changed. This article describes the history of respiratory CPG research and, more specifically, explains how studies concerning the regulation of breathing parameters affect the creation of new hypotheses and theoretical models of the neural control of respiration. Comparing studies on the generators of …

A growing body of evidence suggests that dysbiosis of the human gut microbiota is associated with neurodegenerative diseases like Alzheimer's disease (AD) via neuroinflammatory processes across the microbiota-gut-brain axis. The gut microbiota affects brain health through the secretion of toxins and short-chain fatty acids, which modulates gut permeability and numerous immune functions. Observational studies indicate that AD patients have reduced microbiome diversity, which could contribute to the pathogenesis of the disease. Uncovering the genetic basis of microbial abundance and its effect on AD could suggest lifestyle changes that may reduce an individual's risk for the disease. Using the largest genome-wide …

Distinct lines of research in both humans and animals point to a specific role of the hippocampus in both spatial and episodic memory function. The discovery of concept cells in the hippocampus and surrounding medial temporal lobe (MTL) regions suggests that the MTL maps physical and semantic spaces with a similar neural architecture. Here, we studied the emergence of such maps using MTL microwire recordings from 20 patients (9 female, 11 male) navigating a virtual environment featuring salient landmarks with established semantic meaning. We present several key findings. The array of local field potentials in the MTL contains sufficient information …

Despite the effectiveness of surgical interventions for the treatment of intractable focal temporal lobe epilepsy (TLE), the substrates that support good outcomes are poorly understood. While algorithms have been developed for the prediction of either seizure or cognitive/psychiatric outcomes alone, no study has reported on the functional and structural architecture that supports joint outcomes. We measured key aspects of pre-surgical whole brain functional/structural network architecture and evaluated their ability to predict post-operative seizure control in combination with cognitive/psychiatric outcomes. Pre-surgically, we identified the intrinsic connectivity networks (ICNs) unique to each person through independent component analysis (ICA), and computed: (1) the …
