The genomic revolution has fundamentally changed how we survey biodiversity on earth. High-throughput sequencing ('HTS') platforms now enable the rapid sequencing of DNA from diverse kinds of environmental samples (termed 'environmental DNA' or 'eDNA'). Coupling HTS with our ability to associate sequences from eDNA with a taxonomic name is called 'eDNA metabarcoding' and offers a powerful molecular tool capable of non-invasively surveying species richness from many ecosystems. Here, we review the use of eDNA metabarcoding for surveying animal and plant richness, and the challenges in using eDNA approaches to estimate relative abundance...

Datura stramonium (DS) is a widespread annual plant, containing atropine, hyoscyamine, and scopolamine, which can produce poisoning with a severe anticholinergic syndrome. Teenagers ingest the roots, seeds or the entire plant to obtain its hallucinogenic and euphoric effects. We presented the case of a 22 year old male who was admitted to the Emergency Room in a coma after consuming Datura stramonium, 2 hours earlier. The patient presented with fever, tachycardia with right bundle branch block, and urinary retention...

BACKGROUND: An approach utilizing the long-read capability of the Oxford Nanopore MinION to rapidly sequence bacterial ribosomal operons of complex natural communities was developed. Microbial fingerprinting employs domain-specific forward primers (16S rRNA subunit), reverse primers (23S rRNA subunit), and a high-fidelity Taq polymerase with proofreading capabilities. Amplicons contained both ribosomal subunits for broad-based phylogenetic assignment (~ 3900 bp of sequence), plus the intergenic spacer (ITS) region (~ 300 bp) for potential strain-specific identification...

We investigated the incidence of post-intubation hypotension (PIH) in hemodynamically stable patients with STEMI requiring rapid sequences intubation (RSI) and medicated with ketamine or midazolam as induction agent. STEMI patients admitted between 1st January 2009 and 1st January 2017 who did not receive any type of inotropic support before the endotracheal intubation (ETI) was reviewed. PIH was defined as a reduction greater than 20% or a drop of systolic blood pressure (SBP) below 90 mmHg within 10 min from the administration of the induction agent [ketamine (1 mg/kg) or midazolam (0...

Rapid sequence intubation (RSI) is the most common method of airway control in the emergency department (ED).(1,2) Administration of an anesthetic agent and a neuromuscular blocking agent (NMBA) optimizes conditions for tracheal intubation and is thought to minimize the risk of aspiration.(3-10) Evidence suggests that RSI improves first pass success and reduces complications in the critically ill.(11-14) This article is protected by copyright.

OBJECTIVES: Desaturation leading to hypoxemia may occur during rapid sequence intubation (RSI). Apneic oxygenation (AO) was developed to prevent the occurrence of oxygen desaturation during the apnea period. The purpose of this study was to determine if the application of AO increases the average lowest oxygen saturation during RSI when compared to usual care (UC) in the emergency setting. METHODS: A randomized controlled trial was conducted at an academic, urban, level 1 trauma center...

BACKGROUND: The development of liver failure is a major problem in critically ill patients. The hepatotoxicity of many drugs, as one important reason for liver failure, is poorly screened for in human models. Rocuronium and succinylcholine are neuromuscular blocking agents used for tracheal intubation and for rapid-sequence induction. OBJECTIVE: We used an in-vitro test with a permanent cell line and compared rocuronium and succinylcholine for hepatotoxicity. DESIGN: In-vitro study...

BACKGROUND: A critical safety component of emergency anesthesia is the avoidance of hypoxemia during the apneic phase of a rapid sequence intubation. Preoxygenation with a bag valve mask (BVM) or anesthetic circuit may be improved with supplemental oxygen by nasal cannula (NC) if there is a mask leak. In addition, NC is recommended for apneic oxygenation after induction and may be placed before preoxygenation. However, the optimum NC flow rate for preoxygenation or whether the presence of NC alone creates a mask leak remains unclear...

We developed a portable system for 16S rDNA analyses consisting of a nanopore technology-based sequencer, the MinION, and laptop computers, and assessed its potential ability to determine bacterial compositions rapidly. We tested our protocols using a mock bacterial community that contained equimolar 16S rDNA and a pleural effusion from a patient with empyema, for time effectiveness and accuracy. MinION sequencing targeting 16S rDNA detected all 20 of the bacterial species present in the mock bacterial community...

Today's short-read sequencing instruments can generate read lengths between 50 bp and 700 bp depending on the specific instrument. These high-throughput sequencing approaches have revolutionized genomic science, allowing hundreds of thousands of full genomes to be sequenced, and have become indispensable tools for many researchers. With greater insight has come the revelation that many genomes are much more complicated than originally thought and include many rearrangements and copy-number variations. Unfortunately, short-read sequencing technologies are not well suited for identifying many of these types of events...

This systemic review was performed to determine whether rocuronium creates intubating conditions comparable to those of succinylcholine during rapid sequence intubation of the trachea. We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2015, Issue 2), MEDLINE (1966 to February Week 2 2015), and EMBASE (1988 to February 14 2015) for any randomised controlled trials or controlled clinical trials that reported intubating conditions comparing rocuronium and succinylcholine for rapid or modified rapid sequence intubation...

BACKGROUND: Convulsive status epilepticus (CSE) is the most common life-threatening childhood neurological emergency. Despite this, there is a lack of high quality evidence supporting medication use after first line benzodiazepines, with current treatment protocols based solely on non-experimental evidence and expert opinion. The current standard of care, phenytoin, is only 60% effective, and associated with considerable adverse effects. A newer anti-convulsant, levetiracetam, can be given faster, is potentially more efficacious, with a more tolerable side effect profile...

BACKGROUND: Convulsive status epilepticus (CSE) is the most common life-threatening neurological emergency in childhood. These children are also at risk of significant morbidity, with acute and chronic impact on the family and the health and social care systems. The current recommended first-choice, second-line treatment in children aged 6 months and above is intravenous phenytoin (fosphenytoin in the USA), although there is a lack of evidence for its use and it is associated with significant side effects...

INTRODUCTION: Rapid sequence intubation (RSI) is not only used in traumatic brain injuries in the out-of-hospital setting, but also for non-traumatic brain pathologies (NTBP) such as brain tumors, meningitis, encephalitis, hypoxic/anoxic brain injury, stroke, arteriovenous malformations, tumors, aneurysms, brain hemorrhage, as well as brain injury due to diabetes, seizures and toxicity, metabolic conditions, and alcohol and drug overdose. Previous research suggests that RSI is common in non-traumatic coma, but with an unknown prevalence of NTBP in those that receive RSI...

BACKGROUND: In a previous study we compared rocuronium and suxamethonium for rapid-sequence induction of general anaesthesia for caesarean section and found no difference in maternal outcome. There was however, a significant difference in Apgar scores. As this was a secondary outcome, we extended the study to explore this finding on a larger sample. METHODS: We included 488 parturients of whom 240 were women from the original study. Women were randomly assigned to receive either rocuronium 1mg/kg (ROC n=245) or suxamethonium 1mg/kg (SUX n=243) after propofol 2mg/kg...
