Correlation Of Serum Calcium With Severity Of Acute Ischaemic Stroke, Ainan Arshad, Saad Bin Zafar Mahmood, Ahmed Ayaz, Mehsa Hashim, Eisha Hanan
Section of Internal Medicine
Stroke results in the death of around 6.5 million people annually with a majority of these occurring in developing countries. Serum calcium has been hypothesised to play a significant role in causing ischaemic stroke. This retrospective observational study was conducted to determine the correlation, if any, between serum calcium and the severity of acute ischaemic stroke in our population. Two hundred and seventy-nine patients admitted with acute ischaemic stroke were enrolled in the study. Of the 279 patients 162 (58%) were male and mean age was 62.4 ± 3.8 years. Characteristics of stroke patients were compared with stroke severity. Mean …

This review provides an update on the neurocognitive phenotype of pediatric obstructive sleep apnea (OSA). Pediatric OSA is associated with neurocognitive deficits involving memory, learning, and executive functioning. Adenotonsillectomy (AT) is presently accepted as the first-line surgical treatment for pediatric OSA, but the executive function deficits do not resolve postsurgery, and the timeline for recovery remains unknown. This finding suggests that pediatric OSA potentially causes irreversible damage to multiple areas of the brain. The focus of this review is the hippocampus, 1 of the 2 major sites of postnatal neurogenesis, where new neurons are formed and integrated into existing circuitry …

What Internal Variables Affect Sensorimotor Rhythm Brain-Computer Interface (Smr-Bci) Performance?, Alex J. Horowitz, Christoph Guger, Milena Korostenskaja
What Internal Variables Affect Sensorimotor Rhythm Brain-Computer Interface (Smr-Bci) Performance?, Alex J. Horowitz, Christoph Guger, Milena Korostenskaja
HCA Healthcare Journal of Medicine
In this review article, we aimed to create a summary of the effects of internal variables on the performance of sensorimotor rhythm-based brain computer interfaces (SMR-BCIs). SMR-BCIs can be potentially used for interfacing between the brain and devices, bypassing usual central nervous system output, such as muscle activity. The careful consideration of internal factors, affecting SMR-BCI performance, can maximize BCI application in both healthy and disabled people. Internal variables may be generalized as descriptors of the processes mainly dependent on the BCI user and/or originating within the user. The current review aimed to critically evaluate and summarize the currently accumulated …

What External Variables Affect Sensorimotor Rhythm Brain-Computer Interface (Smr-Bci) Performance?, Alex J. Horowitz, Christoph Guger, Milena Korostenskaja
HCA Healthcare Journal of Medicine
Sensorimotor rhythm-based brain-computer interfaces (SMR-BCIs) are used for the acquisition and translation of motor imagery-related brain signals into machine control commands, bypassing the usual central nervous system output. The selection of optimal external variable configuration can maximize SMR-BCI performance in both healthy and disabled people. This performance is especially important now when the BCI is targeted for everyday use in the environment beyond strictly regulated laboratory settings. In this review article, we summarize and critically evaluate the current body of knowledge pertaining to the effect of the external variables on SMR-BCI performance. When assessing the relationship between SMR-BCI performance and …

Contrasting to the established role of the hypothalamic agouti-related protein (AgRP) neurons in feeding regulation, the neural circuit and signaling mechanisms by which they control energy expenditure remains unclear. Here, we report that energy expenditure is regulated by a subgroup of AgRP neurons that send non-collateral projections to neurons within the dorsal lateral part of dorsal raphe nucleus (dlDRN) expressing the melanocortin 4 receptor (MC4R), which in turn innervate nearby serotonergic (5-HT) neurons. Genetic manipulations reveal a bi-directional control of energy expenditure by this circuit without affecting food intake. Fiber photometry and electrophysiological results indicate that the thermo-sensing MC4RdlDRN neurons …

Upregulation of voltage-gated sodium channels (VGSCs) and Na+/K+-ATPase (sodium pumps) is common across most malignant carcinomas. Targeted osmotic lysis (TOL) is a developing technology in which the concomitant stimulation of VGSCs and pharmacological blockade of sodium pumps causes rapid selective osmotic lysis of carcinoma cells. This treatment of cervical carcinoma is evidence that TOL is a safe, well-tolerated and effective treatment for aggressive advanced carcinomas that has the potential to extend life without compromising its quality. TOL is likely to have broad application for the treatment of advanced-stage carcinomas.

While the median survival in patients with glioblastoma has not improved significantly over the past decade, aggressive attempts have been made on palliation and improving quality of life in these patients. A confluence of two debilitating pathologies which massively distorts the normal day-to-day functioning of the patients who experience it, seizures in glioblastoma patients portends a poor prognosis. There exists a paucity of reported seizure outcomes after glioblastoma treatment in neurosurgical literature. Herein we present a review examining post-operative seizure control in patients with glioblastoma.

It does not come as a surprise that the introduction of an unprecedented treatment for a recently notorious disease will cause concerns and raise some questions. As a race we have become cautious over the centuries about what treatment modalities we accept and reject. With the advent of social media and endless sources of information we find ourselves standing at an intersection of many pathways, thinking meticulously where to go from there? At one point the widely available stats and the complex way in which these vaccines work do not really interest the general population as much as how they …

Dissertations, Theses, and Capstone Projects
Traumatic brain injury (TBI) is one of the most common causes of death and disability worldwide, yet accurate in vivo detection of TBI neuropathology remains challenging due to complexities in the structural and functional changes observed post-injury as well as limitations in conventional neuroimaging modalities. Although advanced neuroimaging techniques such as arterial spin labeling (ASL) can noninvasively assess cerebral blood flow (CBF) changes observed post-injury, this technique is underutilized in TBI research partly due to the low signal-to-noise-ratio (SNR) inherent in ASL imaging. The aim of the current study is to examine the use of machine learning, specifically a Support …

Anti N-methyl-D-aspartate receptor (NMDA)receptor encephalitis is one of the most common type of auto immune encephalitis. Its diagnosis is often delayed due to initial clinical presentation with psychiatric clinical features. Initial clinical features resemble those of acute psychosis or depression which later evolve into frank neurological dysfunction. This was first described in association with ovarian teratoma, but it was later also found to exist without neoplastic association and in men as well. It occurs more frequently in younger age group, mostly below 50 years of age. Diagnosis is established with the help of cerebrospinal fluid (CSF) analysis for oligo clonal …

Determine if hypomagnesemia & hypocalcemia on admission was associated with ICH and outcome.
Magnesium is a vascular smooth muscle relaxant and appears to provide protection against cellular injury in experimental stroke models. The implication of low serum magnesium in primary ICH is not well defined.
All patients with a primary ICH presented to PIMS, Islamabad prospectively analyzed in a pilot study. Demographics, initial lab values, ICH location, Mg+2 level, NIHSS & MRS at presentation were recorded. All patients with INR <= 1.5 were included in this study. We took normal serum magnesium in our study was 1.8 - 2.5 mEq/dL. Statistical significance was determined using linear regression adjusting for admission systolic blood pressure (SBP).
We identified 66 patients who met the inclusion criteria. The mean age was 52.76 years with minimum and maximum age …

Parenting is considered imperative in the development of juvenile's cognitions, and beliefs. The parent-child relationship might significantly influence juvenile’s thought patterns and social communications. Different parenting styles perhaps indicate criminal involvement of juveniles, resultantly turns them into delinquent. The present study was done to discover whether parental authority styles moderate the path that links criminal thinking styles to criminal social identity amongst juvenile delinquents. Participants of the study were 211 juvenile delinquents who responded on Juvenile Criminal Thinking Styles’ Inventory (Sana & Rafiq, 2019), Measure of Criminal Social Identity (Boduszek, et al., 2012), Parental Authority Questionnaire (Babree, 1997) and approached …

Neurological deterioration after acute ischemic stroke (AIS)is a common occurrence, leading to increased mortality, morbidity, and poor quality of life among stroke survivors. Recognition of the individuals at a greater risk for neurological deterioration may contribute to making early decisions and monitoring the therapy. Neurological deterioration arises in up to 40% of subjects after AIS during hospitalization and is followed by neurological and functional debility. Numerous predictors have been devised that predict this progression. This includes preliminary assessment of the severity of stroke, brainstem infarction, hyperglycemia, atrial fibrillation, diabetes mellitus and substantial fluctuations in blood pressure. Sequential observations, in depth …

Migraine is considered as the second leading cause of disability worldwide, most commonly seen in young women. Skipping meals, dehydration and fasting are among many triggering factors which have been described in literature as a cause of increased frequency and severity of migraine attacks. The underlying pathophysiology, prevention and management of fasting induced migraine has been documented, however, there is a lack of randomized controlled trials for the same. This review article discusses these important aspects in the light of published literature and gives directions on future areas of research.
