CONTEXT: Intraosseous (IO) access is an established route of administration in resuscitation situations. Patients with serious poisoning presenting to the emergency department may require urgent antidote therapy. However, intravenous (IV) access is not always readily available. OBJECTIVE: This study reviews the current evidence for IO administration of antidotes that could be used in poisoning. The primary outcome was mortality as a surrogate of efficacy. Secondary outcomes included hemodynamic variables, electrocardiographic variables, neurological status, pharmacokinetics outcomes, and adverse effects as defined by each article...

Meiotic drivers are selfish genes that bias their transmission into gametes, defying Mendelian inheritance. Despite the significant impact of these genomic parasites on evolution and infertility, few meiotic drive loci have been identified or mechanistically characterized. Here, we demonstrate a complex landscape of meiotic drive genes on chromosome 3 of the fission yeasts Schizosaccharomyces kambucha and S. pombe. We identify S. kambucha wtf4 as one of these genes that acts to kill gametes (known as spores in yeast) that do not inherit the gene from heterozygotes...

BACKGROUND/AIM: Aluminum phosphide (AlP) is commonly used as a fumigant in developing countries. Induction of oxidative stress is one of the most important mechanisms of its toxicity. In this regard, and considering that there is no specific antidote for its treatment, the aim of this study was to evaluate the effect of vitamin E in the treatment of acute AlP poisoning. MATERIALS AND METHODS: This was a clinical trial on acute AlP poisoned patients. All patients received supportive treatment...

PURPOSE: Elderly patients with multimorbidity are especially vulnerable to adverse drug events (ADEs) and had high prevalence rates. Identifying ADEs is essential for enabling timely interventions that can mitigate the adverse events detected and for developing targeted strategies to prevent their occurrence as well as to monitor implementation. The aim of this study was to develop a set with appropriate triggers for detecting potential ADEs in elderly patients with multimorbidity. METHODS: A modified Delphi methodology was used to reach consensus...

STUDY OBJECTIVE: Acetaminophen (APAP) overdose is the leading cause of acute liver injury in the United States. Patients with elevated plasma acetaminophen concentrations (PAC) require hepatoprotective treatment with N-acetylcysteine (NAC). These patients have been primarily risk-stratified using the Rumack-Matthew nomogram. Previous studies of acute APAP overdoses found that the nomogram failed to accurately predict the need for the antidote. The objectives of this study were to develop a population pharmacokinetic (PK) model for APAP following acute overdose and evaluate the utility of population PK model-based Bayesian forecasting in NAC administration decisions...

The modification of an idealized infinite bulk system by dimensional reduction or structural distortion results in quantum confinement effects (QCEs). For example, dimensional reduction of a black phosphorus structure leads to the realization of few-layer systems, creation of edges and surfaces, nanoribbons, quantum dots, and antidot lattices while structural distortion involves simple bending (including nanotubes) and rippling. Black phosphorus ('phosphorene' in the single-layer limit) has been of recent interest due to its relatively large charge carrier mobility and moderate semiconducting band gap, which remains direct irrespective of the number of layers...

Nucleic acid ligands, aptamers, harbor the unique characteristics of small molecules and antibodies. The specificity and high affinity of aptamers enable their binding to different targets, such as small molecules, proteins, or cells. Chemical modifications of aptamers allow increased bioavailability. A further great benefit of aptamers is the antidote (AD)-mediated controllability of their effect. In this study, the AD-mediated complexation and neutralization of the thrombin binding aptamer NU172 and Toll-like receptor 9 (TLR9) binding R10-60 aptamer were determined...

Armando Tripodi
The patient reported by Simon et al. [1] was on dabigatran and received idarucizumab for immediate reversal of anticoagulation. Measurement of dabigatran concentration showed that the antidote administration was successful, but after a few hours, there was a rebound in the plasma levels of dabigatran that was greater than expected based on previous reports [2, 3]. The authors correctly pointed out two relevant issues that emerged from this case report. First, the administration of the recommended dose of idarucizumab (though effective in neutralizing dabigatran) might not be sufficient to secure sustained reversal of the drug effect in all situations...

Thrombosis is a leading cause of morbidity and mortality in the United States. Arterial and venous thromboses are implicated in the pathogenesis of major disorders, including myocardial infarction, ischemic stroke, and venous thromboembolism. Over the past decade, direct oral anticoagulants (DOACs) (eg, direct thrombin inhibitor and factor Xa [FXa] inhibitors) have been adopted as alternatives to warfarin due to their clinical advantages and efficacy for the treatment of thrombosis. As with all anticoagulants, treatment with DOACs is associated with a risk of major bleeding, including life-threatening gastrointestinal bleeds and intracranial hemorrhages (ICHs)...

Drug-induced injury has attracted increasing attention in public health issues. Among them, hepatotoxicity has been regarded as the leading clinical problem caused by drug toxicity. However, owing to the complexity of the involved pathophysiological mechanisms and the lack of noninvasive, straightforward, and real-time tools, drug-induced hepatotoxicity has rarely been predicted satisfactorily. In this paper, by utilizing the reactive species peroxynitrite (ONOO(-)) as a biomarker, we present a two-photon fluorescent probe, TP-KA, holding rapid response, high specificity and sensitivity towards ONOO(-), to investigate drug (acetaminophen and tolcapone)-related liver injury and the remediate effect of N-acetyl cysteine (NAC)...

organophosphorus compounds act as irreversible inhibitors of the vital enzyme acetylcholinesterase (AChE). this leads in the accumulation of acetylcholine (ACh) leading to cholinergic crisis and death. The main therapeutic approach is based on immediate administration of an ache reactivator as an antidote enabling recovery of the ache function. Areas covered: This review covers the development of AChE reactivators in order to introduce a new efficient drug that will overcome significant failures of common antidotes...

Antithrombotic and antiplatelet therapy is widely used for primary and secondary prevention of venous and arterial diseases. Hemorrhage is a frequent complication in patients taking these drugs, especially during and post invasive procedures. There are several oral anticoagulants and antiplatelet drugs that differ from each other in the mechanism of action and metabolism, the need for drug monitoring, antidote, and the peri-procedural management of the drug. The risk of bleeding in gastrointestinal endoscopic procedures can be high (≥ 1...

Aluminum phosphide (AlP), one of the most commonly used pesticides worldwide, has been the leading cause of self-poisoning mortalities among many Asian countries. The heart is the main organ affected in AlP poisoning. Melatonin has been previously shown to be beneficial in reversing toxic changes in the heart. The present study reveals evidence on the probable protective effects of melatonin on AlP-induced cardiotoxicity in rats. The study groups included a control (almond oil only), ethanol 5% (solvent), sole melatonin (50 mg/kg), AlP (16...

Dabigatran, a direct thrombin inhibitor and one of the new class of direct oral anticoagulants, is increasingly used in preference to warfarin because of its efficacy and ease of administration. However, because the drug is cleared by the kidneys, it can accumulate in plasma and increase the risk for bleeding in patients with decreased kidney function. We report a patient with end-stage liver disease who developed life-threatening hemorrhage and acute kidney injury while taking dabigatran, 150mg, twice daily...

BACKGROUND: Run Rat® is a rodenticide widely used against small mammals. It comprises of a minimum of 32% zinc phosphide which is highly toxic in acute exposures to humans. It may be consumed accidentally or intentionally. It enters the body via skin, respiratory and gastrointestinal tracts. Zinc phosphide is hydrolyzed by the gastric acid and is transformed into phosphine gas. Phosphine is a respiratory toxin that inhibits cytochrome C oxidase system resulting in renal failure and liver failure...

Since direct oral anticoagulants (DOAC) have become available, use of anticoagulant treatment has become easier and safer-for patients suffering from thromboembolic diseases as well as for patients with atrial fibrillation: Because of constant bioavailability, fixed dose regimen treatment is possible, monitoring not necessary and severe bleeding complications-particularly intracranial hemorrhages-rare in comparison to vitamin K anticoagulants. To gain all these advantages, it is essential to give DOAC in the correct dosage...

It has been demonstrated that peripheral infections accompanied by neuroinflammation may modify brain development or affect normal brain aging and represent major risk factors for the development of neurological disorders. A wide range of synthetic and natural compounds with anti-inflammatory properties have been evaluated in animal models of neuroinflammation and neurodegeneration as an adjuvant therapeutic strategy. In the present study we have demonstrated for the first time that sodium thiosulphate (STS), a known antidote approved for treatment of certain medical conditions, is capable of reducing brain inflammation caused by systemic LPS administration...
