Meta-transcriptomic profiling of functional variation of freshwater microbial communities induced by an antidepressant sertraline hydrochloride.

Sci Total Environ 2021 Apr 30;786:147434. Epub 2021 Apr 30.

College of Environment, Zhejiang University of Technology, Hangzhou 310014, PR China.

Sertraline hydrochloride (Ser-HCl) is an effective and commonly used antidepressant drug, which is also frequently detected in aquatic environments. Our previous research showed that Ser-HCl changes the community composition of aquatic microbiome, but the understanding of the expression of functional pathways in microbial communities is still incomplete; to address this knowledge gap, we used meta-transcriptomics analysis to evaluate the toxicity of Ser-HCl to natural aquatic microbial communities cultured in laboratory microcosms. Meta-transcriptomic results show that a 15-day exposure to 50 μg/L Ser-HCl significantly changed the functional expression activity of aquatic microbial communities. Read More

Aquat Toxicol 2021 May 12;234:105808. Epub 2021 Mar 12.

NORMANDIE UNIV, UNILEHAVRE, FR CNRS 3730 SCALE, UMR-I02, Environmental Stress and Biomonitoring of Aquatic Environments (SEBIO), 76600 LE HAVRE, France. Electronic address:

Juvenile crabs of Carcinus maenas thrive in coastal waters reputed to be the receptacle of continental pollution. Amongst the many pollutants encountered, antidepressants, such as fluoxetine (FLX) and venlafaxine (VEN), often detected at the ng•L range, are particularly worrying because of their action on the levels of monoamines, such as serotonin, noradrenaline and dopamine. In crustaceans, those monoamines are involved in colour change through their action on neuropeptide hormones. Read More

Hunting the eagle killer: A cyanobacterial neurotoxin causes vacuolar myelinopathy.

Science 2021 03;371(6536)

Warnell School of Forestry and Natural Resources, University of Georgia, Athens, GA, USA.

Vacuolar myelinopathy is a fatal neurological disease that was initially discovered during a mysterious mass mortality of bald eagles in Arkansas in the United States. The cause of this wildlife disease has eluded scientists for decades while its occurrence has continued to spread throughout freshwater reservoirs in the southeastern United States. Recent studies have demonstrated that vacuolar myelinopathy is induced by consumption of the epiphytic cyanobacterial species growing on aquatic vegetation, primarily the invasive Here, we describe the identification, biosynthetic gene cluster, and biological activity of aetokthonotoxin, a pentabrominated biindole alkaloid that is produced by the cyanobacterium We identify this cyanobacterial neurotoxin as the causal agent of vacuolar myelinopathy and discuss environmental factors-especially bromide availability-that promote toxin production.

Effect of a New Lithium Preparation on the Behavior of CBA/CaLac Mice in an Experimental Conflict Model.

Bull Exp Biol Med 2021 Feb 13;170(4):436-439. Epub 2021 Mar 13.

Research Institute of Clinical and Experimental Lymphology - Affiliated Branch of the Federal Research Centre Institute of Cytology and Genetics, Siberian Division of the Russian Academy of Sciences, Novosibirsk, Russia.

The use of lithium drugs in clinical practice requires constant monitoring of lithium plasma concentration, because toxicity is sometimes observed at therapeutic concentrations of lithium. This is often associated with fluctuations of plasma concentration of lithium ions after intake of individual doses. Therefore, the use of a porous carrier providing a stable blood level of the drug is extremely promising and important for clinical practice. Read More

Gene alteration in zebrafish exposed to a mixture of substances of abuse.

Environ Pollut 2021 Jun 24;278:116777. Epub 2021 Feb 24.

Department of Biology, Murray State University, Murray, KY, United States.

A recent surge in the use and abuse of diverse prescribed psychotic and illicit drugs necessitates the surveillance of drug residues in source water and the associated ecological impacts of chronic exposure to the aquatic organism. Thirty-six psychotic and illicit drug residues were determined in discharged wastewater from two centralized municipal wastewater treatment facilities and two wastewater receiving creeks for seven consecutive days in Kentucky. Zebrafish (Danio rerio) larvae were exposed to the environmental relevant mixtures of all drug residues, all illicit drugs, and all prescribed psychotic drugs. Read More

Natural daily patterns in fish behaviour may confound results of ecotoxicological testing.

Environ Pollut 2021 May 13;276:116738. Epub 2021 Feb 13.

Animal Ecology, Global Change and Sustainable Development, KU Leuven, Leuven, Belgium; Centre for Environmental Management, University of the Free State, Bloemfontein, South Africa. Electronic address:

Low doses of neuroactive chemicals end up in the environment and disrupt behaviour of non-target organisms. Although a whole range of studies have documented pollutant-induced changes in behaviour, natural daily variability in behaviour is rarely taken into account. This is surprising because biological rhythms may affect the outcome of experiments, are adaptive and are expected to be sensitive to neurochemical exposure. Read More

New psychoactive substances (NPS) and serotonin syndrome onset: A systematic review.

Exp Neurol 2021 May 8;339:113638. Epub 2021 Feb 8.

Psychopharmacology, Drug Misuse & Novel Psychoactive Substances Research Unit, School of Life and Medical Sciences, University of Hertfordshire, Hatfield, United Kingdom; Swansea University Medical School, Institute of Life Sciences 2, Swansea University, Swansea, United Kingdom.

The use of several new psychoactive substances (NPS) has become very popular and is posing global health risks. Chemically and pharmacologically diverse molecules are constantly emerging and are presenting with a wide range of clinical implications. Serotonin toxicity, and specifically Serotonin Syndrome (SS), might develop as a result of an over-activation of the serotoninergic system caused by several mechanisms resulting in a classic triad of altered mental status, neuromuscular effects, and autonomic hyperactivity.

[Therapeutic drug monitoring of antidepressants: Why venlafaxine is the most monitored drug? A review of literature].

Therapie 2021 Jan 23. Epub 2021 Jan 23.

Service de pharmacologie toxicologie et pharmacovigilance, CHU de Limoges, 87000 Limoges, France.

Venlafaxine is the third most frequently prescribed antidepressant in France the last decade, with about 400,000 daily doses. Therapeutic drug monitoring (TDM) of this medication, by measuring the active moiety venlafaxine (V) and O-desmethylvenlafaxine (ODV), is recommended (level of recommendation 2). However, this antidepressant seems to be the one for which clinicians most often use TDM, much more frequently than escitalopram, which is more prescribed and for which TDM is also recommended.

Zygotic exposure to venlafaxine disrupts cortisol stress axis activity in multiple generations of zebrafish.

Environ Pollut 2021 Apr 20;274:116535. Epub 2021 Jan 20.

Department of Biological Sciences, University of Calgary, 2500 University Drive NW, Calgary, Alberta, T2N 1N4, Canada. Electronic address:

Ubiquitous use of antidepressants has resulted in increased concentrations of these pharmaceuticals in waterways receiving municipal wastewater effluent. Amongst these, venlafaxine, a selective serotonin and norepinephrine reuptake inhibitor, is commonly found at concentrations surpassing 1 ppb in surface waters. We recently showed that the deposition of venlafaxine in zebrafish (Danio rerio) embryos impacts neural development in the hypothalamus, suggesting the possibility of neuroendocrine disruptions due to this antidepressant.
