Risperidone-Induced Hypothermia in a Cerebral Palsy Patient: A Case Report and Literature Review.

Cerebral palsy (CP) is a debilitating disorder that can lead to life-long disability, with a high incidence in Saudi Arabia. Secondary epilepsy and cardiac complications are common in CP patients. We present a rare case of a 17-year-old female with CP, attention-deficit hyperactivity disorder (ADHD), secondary epilepsy, and a history of post-cardiac arrest, with home medications carbamazepine, risperidone, and sodium valproate.

Comparison of Temporal Artery and Rectal Temperature Measurement During Cooling and Rewarming in Neonates Treated for Hypoxic Ischemic Encephalopathy.

Background: Finding an accurate and simple method of thermometry in the neonatal intensive care unit is important. The temporal artery thermometer (TAT) has been recommended for all ages by the manufacturer; however, there is insufficient evidence for the use of TAT in infants, especially to detect hypothermia.

Purpose: To assess the accuracy of the TAT in hypothermic neonates in comparison to a rectal thermometer.

Sex Differences in Neurological Outcome at 6 and 12 Months Following Severe Traumatic Brain Injury. An Observational Analysis of the OXY-TC Trial.

The effect of sex in outcomes after severe traumatic brain injury (TBI) remains uncertain. We explored whether outcomes differed between women and men after standardized care management during the first 5 days in the intensive care unit (ICU). This study was an observational analysis of the OXY-TC multicenter randomized clinical trial between June 15, 2016 and April 17, 2021.

Methionine Sulfoximine as a Tool for Studying Temporal Lobe Epilepsy: Initiator, Developer, Attenuator.

Methionine sulfoximine (MSO) is a compound originally discovered as a byproduct of agene-based milled flour maturation. MSO irreversibly inhibits the astrocytic enzyme glutamine synthase (GS) but also interferes with the transport of glutamine (Gln) and of glutamate (Glu), and γ-aminobutyric acid (GABA) synthesized within the Glu/Gln-GABA cycle, in this way dysregulating neurotransmission balance in favor of excitation. No wonder that intraperitoneal administration of MSO has long been known to induce behavioral and/or electrographic seizures.

S100A8-CAMKK2-AMPK axis confers the protective effects of mild hypothermia against cerebral ischemia-reperfusion injury in rats.

To investigate the neuroprotective mechanism of mild hypothermia (MH) in ameliorating cerebral ischemia reperfusion (IR) injury. The Pulsinelli's four-vessel ligation method was utilized to establish a rat model of global cerebral IR injury. To investigate the role of S100A8 in MH treatment of cerebral IR injury, hippocampus-specific S100A8 loss or gain of function was achieved using an adeno-associated virus system.

Identification of hypothermia-inducing neurons in the preoptic area and activation of them by isoflurane anesthesia and central injection of adenosine.

Hibernation and torpor are not passive responses caused by external temperature drops and fasting but are active brain functions that lower body temperature. A population of neurons in the preoptic area was recently identified as such active torpor-regulating neurons. We hypothesized that the other hypothermia-inducing maneuvers would also activate these neurons.

Background: The effect of targeted temperature management (TTM) combined with decompressive craniectomy (DC) on poor-grade aneurysmal subarachnoid hemorrhage (aSAH) has not been previously addressed in the literature. This study aims to investigate the therapeutic outcomes of the combination of TTM and DC in patients with poor-grade aSAH.

Methods: This study represents a secondary analysis of the Multicenter Clinical Research on Targeted Temperature Management of Poor-grade Aneurysmal Subarachnoid Hemorrhage (High-Quality TTM for PaSAH), a multicenter prospective study conducted in China.

Impact of mild hypothermic circulatory arrest on surgical outcomes in acute type a aortic dissection patients: a single-centre study.

Background: As hypothermic circulatory arrest (HCA) is being more frequently induced in patients undergoing aortic arch surgery, its safety at different degrees has become a crucial area of study. The aim of this study was to assess the surgical outcomes of mild hypothermic circulatory arrest (MI-HCA) during aortic arch surgery.

Methods: Acute type A aortic dissection (ATAAD) patients who underwent total arch replacement (TAR) and frozen elephant trunk (FET) surgery between January 2014 and December 2023 were enrolled in this study.

Dexmedetomidine-associated hypothermia in critical trauma: A case report and literature analysis.

Rationale: Hypothermia, defined as a core body temperature below 35°C, is a common and serious complication in severe trauma patients, often worsened by hemorrhage and medical interventions. Dexmedetomidine, an α2-adrenergic agonist used for sedation in intensive care units, has known thermoregulatory effects; however, its association with hypothermia in trauma patients remains insufficiently explored.

Patient Concerns: A 40-year-old male with severe polytrauma from a motor vehicle accident presented in distress, with hypotension, tachycardia, and a baseline temperature of 35.

Physiological and behavioral stability of newborns on therapeutic hypothermia for hypoxic-ischemic encephalopathy during parental holding.

Background: Physical separation contributes to parental trauma and poor bonding in the context of therapeutic hypothermia (TH) for hypoxic-ischemic encephalopathy (HIE). Parental holding (PH) may improve parents' experience. We aim to determine the physiological and behavioral stability of the newborn held by the parents during TH.

Association Between the Timing of Coronary Angiography, Targeted Temperature Management, and Neurological Outcomes After Out-of-Hospital Cardiac Arrest: A Nationwide Population-Based Registry Study in Korea.

Background: Coronary angiography (CAG) and targeted temperature management (TTM) may improve clinical outcomes after out-of-hospital cardiac arrest. This study aimed to assess whether the intervention effects differed according to timing and percutaneous coronary intervention (PCI) performance.

Methods And Results: Adult patients with presumed cardiac cause who underwent CAG and TTM within 24 hours following out-of-hospital cardiac arrest were included from the Korean nationwide out-of-hospital cardiac arrest registry.

Investigation into the influence of mild hypothermia on regulating ferroptosis through the P53-SLC7A11/GPX4 signaling pathway in sepsis-induced acute lung injury.

Background: Sepsis-induced acute lung injury (S-ALI) significantly contributes to unfavorable clinical outcomes. Emerging evidence suggests a novel role for ferroptosis in the pathophysiology of ALI, though the precise mechanisms remain unclear. Mild hypothermia (32-34 °C) has been shown to inhibit inflammatory responses, reduce oxidative stress, and regulate metabolic processes.

Cryogenic, but not hypothermic, preservation disrupts the extracellular matrix of cell sheets.

Cell sheet (CS)-based approaches hold significant potential for tissue regeneration, relying on the extracellular matrix (ECM) for success. Like in native tissues, the ECM provides structural and biochemical support for cellular homeostasis and function. Effective preservation strategies that maintain ECM integrity are critical to enhance the therapeutic potential of CS-based approaches.

Background: Sepsis-associated encephalopathy (SAE) may be worsened by early systemic insults. We aimed to investigate the association of early systemic insults with outcomes of critically ill patients with severe SAE.

Methods: We performed a retrospective analysis using data from the French OUTCOMEREA prospective multicenter database.

Ionised calcium levels during trauma resuscitation in predicting outcomes-a prospective cohort study.

Background: Haemorrhage remains the leading cause of preventable mortality following trauma, often aggravated by the acidosis, hypothermia and coagulopathy-the lethal triad of trauma. However, the impact of trauma-induced hypocalcemia on the haemorrhage remains unclear. It is intuitive to consider perturbations of ionised calcium early during trauma resuscitation in acutely injured patients given its pathophysiological significance for an improved outcome.

Reverse transcriptase inhibitors diminish systemic proinflammatory responses to bacterial pathogens.

Bacterial infections can induce exuberant immune responses that can damage host tissues. Previously, we demonstrated that systemic infection in mice causes tissue damage in the liver. This liver necrosis is associated with the expression of endogenous retroviruses, chromosomally integrated retroviruses that encode a reverse transcriptase.

Impact of hyper- and hypothermia on cellular and whole-body physiology.

The incidence of heat-related illnesses and heatstroke continues to rise amidst global warming. Hyperthermia triggers inflammation, coagulation, and progressive multiorgan dysfunction, and, at levels above 40 °C, can even lead to cell death. Blood cells, particularly granulocytes and platelets, are highly sensitive to heat, which promotes proinflammatory and procoagulant changes.

Association between cerebrospinal fluid levels of neuro-specific enolase after hypothermia alone and in combination with neurodevelopmental outcomes at age six years.

Background: Hypoxic-ischemic encephalopathy (HIE) is still associated with death and sequelae including cerebral palsy and intellectual disability despite induced hypothermia. Biomarkers, as early predictive indicators of adverse outcomes, are lacking.

Aims: To investigate whether post-rewarming cerebrospinal fluid (CSF)-neuro-specific enolase (NSE) levels after hypothermia are associated with neurodevelopmental outcomes at age six years, alone or when combined with amplitude-integrated electroencephalography (aEEG) and brain magnetic resonance imaging (MRI), as neuroimaging and neurophysiological indicators, respectively.
