The goal of this clinical trial is to explore the effect of FDA-approved antiseizure drugs in the brain connectivity patterns of severe and moderate acute brain injury patients with suppression of consciousness. The main questions it aims to answer are:
* Does the antiseizure medication reduce the functional connectivity of seizure networks, as identified by resting state functional MRI (rs-fMRI), within this specific target population?
* What is the prevalence of seizure networks in patients from the target population, both with EEG suggestive and not suggestive of epileptogenic activity?
Participants will have a rs-fMRI and those with seizure networks will receive treatment with two antiseizure medications and a post-treatment rs-fMRI. Researchers will compare the pretreatment and post-treatment rs-fMRIs to see if there are changes in the participant's functional connectivity including seizure networks and typical resting state networks.

PHENObarbital for the MANagement of Severe Acute ALcohol Withdrawal Syndrome (PHENOMANAL): a Prospective Randomized Feasibility Study.

Severe acute alcohol withdrawal syndrome is a potentially life-threatening condition characterized by agitation, confusion, abnormal heart rhythms and seizures. Typically, clinicians treat the symptoms of alcohol withdrawal with a class of medications known as benzodiazepines (e.g., Valium). These medications have a short duration of activity and require repeated administration, often every hour or less, to reduce the symptoms of alcohol withdrawal. Many patients suffer complications related to inadequate treatment of alcohol withdrawal (e.g., abnormal heart rhythms, aspiration, seizures) resulting in admission to an intensive care unit and prolonged hospital stay, all of which increase healthcare costs. Although alcohol withdrawal is common, especially among disadvantaged (e.g., homeless) patients, limited funding is available to advance the care of patients suffering from alcohol withdrawal. A safe and effective treatment for severe alcohol withdrawal would benefit patients and our healthcare system.
Phenobarbital is an inexpensive, commonly available medication that is typically used to treat seizures. A key advantage of phenobarbital is that its calming effect lasts for a long period of time and it can be given as a 'one-time-dose' intravenously, so that it both prevents and treats withdrawal symptoms and reduces the need for repeated benzodiazepines. Through better symptom control, phenobarbital is expected to reduce the costs and complications of alcohol withdrawal. At present, physicians rarely use phenobarbital for this purpose, and additional research is needed for this medication to become part of routine care in clinical practice.
The PHENOMANAL pilot trial will assess safety and whether clinicians can administer a single dose of phenobarbital intravenously, in addition to benzodiazepines, compared to benzodiazepines alone for treating patients with severe alcohol withdrawal. This information will inform the design of a larger clinical trial. For patients, the PHENOMANAL trial has the potential to revolutionize how patients suffering from severe alcohol withdrawal are treated. For society and the healthcare system, phenobarbital is expected to reduce the complications and costs associated with severe alcohol withdrawal.

NCT04320940 / TerminatedPhase 3

A Randomized, Double-Blind, Controlled Study to Assess the Efficacy and Safety of Intravenous Phenobarbital in Neonatal Seizures

This is a randomized, double-blind, parallel-group, Phase 3 study to evaluate the efficacy of the administration of phenobarbital sodium injection in neonates who have suffered from electrographic or electroclinical seizure. As neonatal seizures can have long-term adverse effects, including death, placebo-controlled studies are not appropriate for this population. This study is designed to show intravenous phenobarbital is effective at preventing subsequent seizures by demonstrating greater efficacy at a higher dose compared to a lower dose.

Hepatic enzyme induction and its potential effect on thyroid hormone metabolism in the metamorphosing tadpole of Xenopus laevis (African clawed frog)

Article

Author: Fujisawa, Takuo ; Tanaka, Hitoshi ; Wada, Kohei ; Yamaguchi, Takafumi

Abstract:

Hepatic enzyme induction, an inherent defense system against xenobiotics, is known to simultaneously affect endocrine system functions in mammals under specific conditions, particularly thyroid hormone (TH) regulation. While this phenomenon has been studied extensively, the pathway leading to this indirect thyroid effect in mammals has unclear applicability to amphibians, despite the importance of amphibian species in assessing thyroid‐disruptive chemicals. Here, we investigated the effects of three well‐known mammalian enzyme inducers—β‐naphthoflavone (BNF), pregnenolone carbonitrile (PCN), and sodium phenobarbital (NaPB)—on the gene expression of phase‐I and phase‐II metabolizing enzymes in Xenopus laevis tadpoles. Waterborne exposure to BNF and PCN significantly induced the expression of both phase‐I (cytochrome P450, CYP) and phase‐II enzymes (UDP‐glucuronosyltransferase, UGT and sulfotransferase, SULT), but in different patterns, while NaPB exposure induced CYP2B expression without affecting phase‐II enzymes in tadpoles, in contrast to mammals. Furthermore, an ex vivo hepatic enzyme activity assay confirmed that BNF treatment significantly increased phase‐II metabolic activity (glucuronidation and sulfation) toward TH. These results suggest the potential for certain mammalian enzyme inducers to influence TH clearance in X. laevis tadpoles. Our findings provide insights into the profiles of xenosensing activity and enzyme induction in amphibians, which can facilitate a better understanding of the mechanisms of indirect effects on the thyroid system via hepatic enzyme induction in nonmammalian species.

[A case of recurrent convulsions caused by acute sulfuryl fluoride gas poisoning].

Article

Author: Su, C H ; Zhang, Q B ; Li, Z H ; Zhang, Y G ; Wang, R

Sulfuryl fluoride is a kind of pesticide with strong permeability, convenient use at low temperature, non-corrosive and other characteristics, which can kill food pests and has strong lethality to termites. In acute sulfuryl fluoride poisoning, patients can see recurrent convulsions, epileptic electroencephalogram abnormalities such as matrix spikes or high amplitude spikes. In this paper, a patient with sulfuryl fluoride poisoning with convulsion-based mental system symptoms was reported, and after clinical treatment with dexamethasone and phenobarbital sodium, the patient was cured and discharged.

Optical controlled and nuclear targeted CECR2 competitor to downregulate CSF-1 for metastatic breast cancer immunotherapy

Article

Author: Chen, Ying ; Yan, Mengyi ; Cheng, Hong ; Cen, Yi ; Li, Shiying ; Yan, Ni ; Chen, Xiayun ; Li, Xinxuan ; Yu, Baixue

The crosstalk between breast cancer cells and tumor associated macrophages (TAMs) greatly contributes to tumor progression and immunosuppression. In this work, cat eye syndrome chromosome region candidate 2 (CECR2) is identified to overexpress in breast cancer patients, which can recognize v-rel avian reticuloendotheliosis viral oncogene homolog A (RelA) and activate nuclear factor κB (NF-κB) to release colony stimulating factor-1 (CSF-1). Pharmacological inhibition of CECR2 by the bromodomain competitor (Bromosporine, Bro) can downregulate CSF-1 to inhibit M2 type TAMs. To amplify the immunotherapeutic effect, a chimeric peptide-based and optical controlled CECR2 competitor (designated as N-PB) is constructed to enhance the nuclear targeted delivery of Bro and initiate an immunogenic cell death (ICD). In vivo results indicate a favorable breast cancer targeting ability and primary tumor suppression effect of N-PB under optical irradiation. Importantly, N-PB downregulates CSF-1 by competitive inhibition of CECR2 and NF-κB(RelA) interactions, thus inhibiting immunosuppressive M2-like TAMs while improving the antitumorigenic M1-like phenotype. Ultimately, the systemic anti-tumor immunity is activated to suppress the metastatic breast cancer in an optical controlled manner. This study provides a promising therapeutic target and reliable strategy for metastatic breast cancer treatment by interrupting immunosuppressive crosstalk between tumor cells and macrophages.
