OBJECTIVE: Mechanical ventilation (MV) in preterm infants (PTI) causes discomfort. Whether it causes pain is controversial. Meta analysis reviews of published work on PTI during MV have shown no clinically significant impact of opioids on pain scales, and hence not recommended for routine use in neonatal intensive care units (NICUs). Similarly regular use of sedative midazolam is also not recommended. Therefore we hypothesized a downward trend in narcotics and sedatives used in MV of PTI in NICUs...

The heterogeneous insular cortex plays an interoceptive role in drug addiction by signaling the availability of drugs of abuse. Here, we tested whether the caudal part of the multisensory posterior insula (PI) stores somatosensory-associated rewarding memories. Using Sprague Dawley rats as subjects, we first established a morphine-induced conditioned place preference (CPP) paradigm, mainly based on somatic cues. Secondly, an electrolytic lesion of the caudal portion of the PI was carried out before and after the establishment of CPP, respectively...

Keratinous matrices - hair and nails - accumulate substances over time and allow retrospective investigation of past consumption. Analysis of these matrices can provide information complementary to blood and urine analysis or can be used as standalone. So far, research has primarily focused on the detection of substances in hair, while studies in nails are scarce. In this study, we assessed concentrations of drugs of abuse and their metabolites in hair, finger- and toenails collected from the same individuals to evaluate differences and correlations between matrices...

Toxicological investigations are often required by clinicians in comatose patients with suspected poisoning. However, the usefulness of toxicological analyses to support a diagnosis of acute poisoning is debated among clinicians and the interpretation of laboratory tests is challenging given the wide diversity of analytical techniques available. We report the case of an 8-year-old boy who was admitted to an intensive care unit with severe respiratory depression and neurological impairment. In order to formulate appropriate hypothesizes about the diagnosis and circumstances of intoxication, clinicians consulted toxicologists for a comprehensive toxicological screening...

Background: The amygdala is one of the nerve centers involved in drug reward. It is suggested that the central nucleus of the amygdala (CeA) is involved in morphine dependency. The CeA gamma-aminobutyric acid-ergic (GABAergic) system is a mediator of morphine rewarding effects. In this research, the effects of stimulation or inhibition of CeA GABA type B (GABAB) receptors on sensitization acquisition to morphine-induced reward was evaluated in Wistar female rats using conditioned place preferential (CPP) method...

Accumulating evidence support the growing non-medical use of morphine during adolescence. Despite this concern which has recently been addressed in some studies, cellular mechanisms underlying the long-term neurobiological and behavioral effects of opiate exposure during this critical period have still remained largely unexplored. Several reports have proposed that subtle long-lasting neurobiological alterations might be triggered by exposure to opiate derivatives or drugs of abuse particularly when this occurs during a critical phase of brain maturation such as adolescence...

The quantification of drugs of abuse in keratinized matrices is becoming of special relevance for monitoring consumption and for post-mortem investigations. We aimed to implement an analytical method for the simultaneous detection of morphine (MORF), 6-monoacetylmorphine (6-MAM), methadone (MET), 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP) and 2-ethyl-5-methyl-3,3-diphenylpyrrolidine (EMDP) in nails. After decontamination, the nail samples (30 mg) were submitted to an alkaline digestion followed by a two-step liquid-liquid and SPE extraction using mixed-mode cation exchange cartridges...

BACKGROUND: It has been long recognized that ensuring analyte stability is of crucial importance in the use of any quantitative bioanalytical method. As analyses are usually not performed directly after collection of the biological samples, but after these have been processed and stored, it is essential that analyte stability be maintained over the relevant storage conditions in order to ensure that the obtained concentration results adequately reflect those directly after sampling. The conservation of urine samples in refrigerated/frozen conditions is strongly recommended; but not always feasible...

Tapentadol, a Schedule II opioid with a combination of µ-opioid activity and norepinephrine reuptake inhibition, is used for the management of moderate to severe acute and chronic pain. Its dual-mechanism of action is thought to reduce opioid-related side effects that can complicate pain management. Since approval, tapentadol has been tracked across multiple outcomes suggesting abuse liability, and a pattern of relatively low, although not absent, abuse liability has been found. This retrospective cohort study further details the abuse liability of tapentadol as an Active Pharmaceutical Ingredient (API) when both immediate-release and extended-release formulations were on the market together (4Q2011 to 2Q2016)...

Hair analysis has been established as a prevalent tool for retrospective drug monitoring. In this study, different extraction solvents for the determination of drugs of abuse and pharmaceuticals in hair were evaluated for their efficiency. A pool of authentic hair from drug users was used for extraction experiments. Hair was pulverized and extracted in triplicate with seven different solvents in a one- or two-step extraction. Three one- (methanol, acetonitrile, and acetonitrile/water) and four two-step extractions (methanol two-fold, methanol and methanol/acetonitrile/formate buffer, methanol and methanol/formate buffer, and methanol and methanol/hydrochloric acid) were tested under accurately equal experimental conditions...
