Oxygen post seizure

People with epilepsy (PWE) are less fit and have an increased risk of sudden cardiac death. Imbalances within the autonomic nervous system (ANS) are believed to mediate some of those effects. However, results are mostly derived from patients whose seizures are refractory to medical therapy. In this study, an exhaustive bicycle ergometer test was delivered to 25 PWE (19 seizure free in the last 6 months) recruited in a community-based setting and 25 age-, sex-, and BMI-matched healthy controls. During the exercise test a 12-channel ECG was recorded and spirometry was carried out to determine the maximal oxygen uptake (VO2 peak) as the gold standard to assess fitness...

BACKGROUND: Neonatal seizures remain a significant cause of morbidity and mortality worldwide. The past decade has resulted in substantial progress in seizure detection and understanding the impact seizures have on the developing brain. Optical monitoring such as cerebral near-infrared spectroscopy (NIRS) and broadband NIRS can provide non-invasive continuous real-time monitoring of the changes in brain metabolism and haemodynamics. AIM: To perform a systematic review of optical biomarkers to identify changes in cerebral haemodynamics and metabolism during the pre-ictal, ictal, and post-ictal phases of neonatal seizures...

Repetitive mild traumatic brain injuries (RmTBIs) are increasingly recognized to have long-term neurological sequelae in a significant proportion of patients. Individuals that have had RmTBIs exhibit a variety of sensory, cognitive, or behavioral consequences that can negatively impact quality of life. Brain tissue oxygen levels ([Formula: see text]) are normally maintained through exquisite regulation of blood supply to stay within the normoxic zone (18-30 mmHg in the rat hippocampus). However, during neurological events in which brain tissue oxygen levels leave the normoxic zone, neuronal dysfunction and behavioral deficits have been observed, and are frequently related to poorer prognoses...

BACKGROUND: We report the first case of COVID-19 associated acute necrotizing encephalopathy (ANE) without pulmonary disease in a patient with an extremely high interleukin-6 (IL-6) level and Ran Binding Protein 2 (RANBP2) mutation. CASE PRESENTATION: A 29-year-old woman recently immunized with inactivated viral vaccine-BBIBP32-CorV (Sinopharm) presented with alteration of consciousness. Her body temperature was 37° Celsius, blood pressure 42/31 mmHg, heart rate 130 bpm, respiratory rate 20 per minute, and oxygen saturation 98%...

BACKGROUND: Posterior reversible encephalopathy syndrome (PRES) is a disorder of reversible vasogenic brain oedema with acute neurologic symptoms. It is a rare but serious disease that affects the central nervous system. PRES is a rare complication of acute post-streptococcal glomerulonephritis (APSGN). High altitude can accelerate vasogenic brain oedema by increasing cerebral blood flow (CBF), impairing cerebral autoregulation and promoting vascular inflammation. We report a case of PRES induced by acute post-streptococcal glomerulonephritis in a high-altitude environment...

Improvements in teamwork and resuscitation science have considerably increased the success rate of cardiopulmonary resuscitation. Cerebral injury, myocardial dysfunction, systemic ischemia and reperfusion response, and precipitating pathology after the return of spontaneous circulation (ROSC) constitute post-cardiac arrest syndrome. Because the entire body is involved in cardiac arrest and the early post-arrest period, protocolized post-arrest care consisting of cardiovascular optimization, ventilation and oxygenation adjustment, coronary revascularization, targeted temperature management (TTM), and control of seizures and blood sugar would benefit survival and neurological outcomes...

Acute brain injury (ABI) occurs frequently in patients receiving venoarterial extracorporeal membrane oxygenation (VA-ECMO). We examined the association between peri-cannulation arterial carbon dioxide tension (PaCO2) and ABI with granular blood gas data. We retrospectively analyzed adult patients who underwent VA-ECMO at a tertiary care center with standardized neuromonitoring. Pre- and post-cannulation PaCO2 were defined as the mean of all PaCO2 values in the 12 hours before and after cannulation, respectively...

BACKGROUND: Though primarily a pulmonary disease, Coronavirus disease 2019 (COVID-19) caused by the SARS-CoV-2 virus can generate devastating disease states that affect multiple organ systems including the central nervous system (CNS). The various neurological disorders associated with COVID-19 range in severity from mild symptoms such as headache, or myalgias to more severe symptoms such as stroke, psychosis, and anosmia. While some of the COVID-19 associated neurological complications are mild and reversible, a significant number of patients suffer from stroke...

BACKGROUND: Pediatric benign laryngeal tumors can often be treated as same-day surgeries. This study identified factors associated with prolonged hospital stay in children undergoing laryngeal surgery for benign tumors. METHODS: A retrospective analysis of records of pediatric patients who underwent laryngeal surgery with a post-op diagnosis of benign tumor was performed with the American College of Surgeons Pediatric National Surgery Quality Improvement Program (ACS-NSQIP-P) database (2014-2018)...

Rett syndrome (RTT) is a severe X-linked progressive neurodevelopmental disorder affecting ~1 in 10,000 females. It is the second most common genetic cause of cognitive disability in girls, after Down syndrome. Girls with this devastating disorder develop relatively normally for 6-18 months, after which they undergo a period of rapid regression. They lose many motor skills, the growth of their brain slows, and they develop repetitive, autistic behaviors and seizures. Autonomic disruptions are a leading cause of early death in RTT, and rescue of breathing deficits is considered a primary goal in the development of therapeutic interventions...

Vaccination has proven effective against infection with SARS-CoV-2, as well as death and hospitalisation following COVID-19 illness. However, little is known about the effect of vaccination on other acute and post-acute outcomes of COVID-19. Data were obtained from the TriNetX electronic health records network (over 81 million patients mostly in the USA). Using a retrospective cohort study and time-to-event analysis, we compared the incidences of COVID-19 outcomes between individuals who received a COVID-19 vaccine (approved for use in the USA) at least 2 weeks before SARS-CoV-2 infection and propensity score-matched individuals unvaccinated for COVID-19 but who had received an influenza vaccine...

OBJECTIVE: Levetiracetam (LEV) efficacy for neonatal seizures is debated. We evaluated LEV as a first line anti-seizure medicine (ASM) in neonates following neonatal congenital heart defect (CHD) repair who did not require extracorporeal membrane oxygenation (ECMO) vs neonates who required ECMO. METHODS: A single center retrospective review of neonates with CHD from 2015 to 2020 was conducted. Neonates were included if seizures were present on continuous EEG after CHD repair either on or off ECMO, and they received LEV as a first line ASM...

Drug-resistant epilepsy (DRE) is a global public health problem. This category includes patients who continue to experience seizures despite long-term anti-epileptic medications. DRE can lead to severe disability and morbidity in older children and adults and is associated with increased risk of mortality than the general population. This report describes the case of a 15-year-old male patient with DRE successfully managed with autologous cell-based and hyperbaric oxygen therapy. The patient underwent two sessions of cell-based therapy consisting of cells derived from the bone marrow, adipose tissue, and peripheral blood followed by neuro-physiotherapy and oxygen therapy...

Hyperbaric oxygen therapy (HBOT) is commonly utilized for various human conditions with a low incidence of major adverse effects (0.002-0.035%). Despite growing use in veterinary patients, there remains a paucity of literature describing its use and associated complications. The purpose of this study was to report clinical use of HBOT in small animals and identify the rate of major adverse events at a university teaching hospital. Electronic medical records were searched for small animals receiving HBOT between November 2012 and February 2020...

BACKGROUND: Respiratory Syncytial Virus (RSV) infection is a significant cause of bronchiolitis and pneumonia, mostly responsible for hospitalization and infant death worldwide. However, in recent years the importance of extrapulmonary RSV manifestations, especially at neurological level, have become evident. Seizures, lethargy, ataxia and status epilepticus are suggestive of brain involvement, but also in their absence a direct neurological damage RSV-related need to be evaluated. CASE PRESENTATION: A 40-day old male infant was admitted to the Emergency Department with severe bronchiolitis and dyspnea...

Background: Potentially curative epilepsy surgery can be offered if a single, discrete epileptogenic zone (EZ) can be identified. For individuals in whom there is no clear concordance between clinical localization, scalp EEG, and imaging data, intracranial EEG (icEEG) may be needed to confirm a predefined hypothesis regarding irritative zone (IZ), seizure onset zone (SOZ), and EZ prior to surgery. However, icEEG has limited spatial sampling and may fail to reveal the full extent of epileptogenic network if predefined hypothesis is not correct...

BACKGROUND: Severe venlafaxine intoxication may cause arrhythmias, cardiac failure, and even cardiac arrest. CASE PRESENTATION: A 48-year-old caucasian male with an extensive psychiatric history ingested a high dose of venlafaxine causing a serum venlafaxine concentration of 12.6 mg/L 24 hours after ingestion. Seven hours post-ingestion, he experienced tonic-clonic seizures, and 8 hours later, takotsubo cardiomyopathy was recognized followed by cardiac arrest...

INTRODUCTION: Rasmussen encephalitis (RE) is a rare inflammatory disease, characterized by unilateral hemispheric atrophy, focal intractable seizures, progressive hemiparesis, and neurological deficits. CASE REPORT: The patient is a young man under pharmacotherapy for epilepsy, exhibiting classical abnormal movements, which are consider typical hallmarks of RE. During clinical care sessions, he presented many episodes of tonic-clonic seizures involving sudden loss of consciousness followed by a post-ictal phase with weakness and interaction difficulty...

Background: This study aims to describe the prevalence of neurologic complications and hospital outcome in adult post-cardiotomy cardiogenic shock (PCS) patients receiving veno-arterial extracorporeal membrane oxygenation (V-A ECMO) support and factors associated with such adverse events. Methods: Four hundred and fifteen adult patients underwent cardiac surgery and received V-A ECMO for more than 24 h because of PCS. Patients were divided into two groups: those who developed a neurological complication and those who did not (control group)...

Neuronal dysfunction due to iron accumulation in conjunction with reactive oxygen species (ROS) could represent an important, yet underappreciated, component of the epileptogenic process. However, to date, alterations in iron metabolism in the epileptogenic brain have not been addressed in detail. Iron-related neuropathology and antioxidant metabolic processes were investigated in resected brain tissue from patients with temporal lobe epilepsy and hippocampal sclerosis (TLE-HS), post-mortem brain tissue from patients who died after status epilepticus (SE) as well as brain tissue from the electrically induced SE rat model of TLE...
