Driving under the influence of drugs (DUID) is a worldwide problem. Several countries adopted DUID legislations which prove their deterrent effect and impact on road safety. However, use of new psychoactive substances (NPS) and prescription drugs is not known as the applied roadside screening tests are not yet adapted for these compounds. In this study, 558 blood samples obtained during roadside controls in Belgium (January to August 2015) after a positive Drugwipe 5S® test and 199 oral fluid (OF) samples obtained from negatively screened test pads were analyzed...

There are various theories to explain the pathophysiology of depression and support its diagnosis and treatment. The roles of monoamines, brain-derived neurotrophic factor (BDNF), and Wnt signaling are well researched, but sonic hedgehog (Shh) signaling and its downstream transcription factor Gli1 are not well studied in depression. Shh signaling plays a fundamental role in embryonic development and adult hippocampal neurogenesis and also involved in the growth of cancer. In this article, we summarize the evidence for the Shh signaling pathway in depression and the potential crosstalk of Shh with Wnt and BDNF...

Major depressive disorder (MDD) is a common neuropsychiatric disorder characterized by diverse symptoms. Although several antidepressants can influence dopamine system in the medial prefrontal cortex (mPFC), but the role of D1R or D2R subtypes of dopamine receptor during anti-depression process is still vague in PFC region. To address this question, we investigate the antidepressant effect of levo-stepholidine (l-SPD), an antipsychotic medication with unique pharmacological profile of D1R agonism and D2R antagonism, and clarified its molecular mechanisms in the mPFC...

The aim of this research was to study the role and trend of antidepressant use as a method of suicide in completed self-poisoning suicides in patients with affective disorders during a 23-year follow up period. The data consisted of 483 completed self-poisoning suicides from 1988 to 2011 in the province of Oulu in Northern Finland (286 men and 197 women). Of the self-poisoning victims, 26.9% (n=130) had hospital-treated unipolar depression and 3.1% (n=15) hospital-treated bipolar disorder. Further, 53.8% (n=70) of those with unipolar depression and 53...

Mounting evidence suggests that aberrations in immune-inflammatory pathways contribute to the pathophysiology of major depressive disorder (MDD), and individuals with MDD may have elevated levels of predominantly pro-inflammatory cytokines and C-reactive protein. In addition, previous meta-analyses suggest that antidepressant drug treatment may decrease peripheral levels of interleukin-1 beta (IL-1β) and IL-6. Recently, several new studies examining the effect of antidepressants on these cytokines have been published, and so we performed an updated meta-analysis of studies that measured peripheral levels of cytokines and chemokines during antidepressant treatment in patients with MDD...

BACKGROUND: Managing expenditures on pharmaceuticals is important for health systems to sustain universal access to necessary medicines. We sought to estimate the size and sources of differences in expenditures on primary care medications among high-income countries with universal health care systems. METHODS: We compared data on the 2015 volume and cost per day of primary care prescription drug therapies purchased in 10 high-income countries with various systems of universal health care coverage (7 from Europe, in addition to Australia, Canada and New Zealand)...

The work presented here explores the grafting of molecularly imprinted nanoparticles (MIN) on silica beads for the development of new chiral stationary phases (CSP). Both solid-phase imprinting and precipitation polymerisation were tested for MIN synthesis though the latter approach was the only one that provided efficient chiral selectors. MIN particles were prepared by iniferter polymerisation initiated by UV radiation, using itaconic acid as functional monomer and ethylene dimethacrylate as cross-linker...

Depression, together with suicide is an important contributor to the burden of disease in Thailand. Until recently, depression has been significantly under-recognized in the country. The lack of response to this health challenge has been compounded by a low level of access to standard care, constraints on mental health personnel and inadequate dissemination of knowledge in caring for people with these disorders. In the past decade, significant work has been undertaken to establish a new evidence-based surveillance and care system for depression and suicide in Thailand that operates at all levels of health-care provision nationwide...

Importance: Benzodiazepines have been prescribed for short periods to patients with depression who are beginning antidepressant therapy to improve depressive symptoms more quickly, mitigate concomitant anxiety, and improve antidepressant treatment continuation. However, benzodiazepine therapy is associated with risks, including dependency, which may take only a few weeks to develop. Objectives: To examine trends in simultaneous benzodiazepine and antidepressant new use among adults with depression initiating an antidepressant, assess antidepressant treatment length by simultaneous new use status, estimate subsequent long-term benzodiazepine use in those with simultaneous antidepressant and benzodiazepine new use, and identify determinants of simultaneous new use and long-term benzodiazepine use...

Vilazodone hydrochloride is the first member in a new class of antidepressants called indolealkylamines and was approved for use in the United States in 2011 for major depressive disorder. It has a combined mechanism of action of a selective serotonin reuptake inhibitor and a partial agonist of serotonin 5-HT1A receptors. It has not been approved for use in the pediatric population, and toxicity from exploratory vilazodone ingestion has been rarely described to date. We describe 2 children with laboratory-confirmed vilazodone ingestions that led to significant toxicity including refractory status epilepticus in 1 patient and likely transient seizure activity in the other...

AIMS: Sedation, as it is often required in critical care, is associated with immobilization, prolonged ventilation, and increased morbidity. Most sedation protocols are based on benzodiazepines. The presented study analyzes the benefit of benzodiazepine-free sedation. METHODS: In 2008, 134 patients were treated according to a protocol using benzodiazepine and propofol (Group 1). In 2009, we introduced a new sedation strategy based on sufentanil, nonsteroidal anti-inflammatory drugs, neuroleptics, and antidepressants, which was applied in 140 consecutive patients (Group 2)...

Genetic research in Psychiatry is viewed by clinicians with both hope and curiosity sometimes mixed with disillusionment. Indeed, in the last 30 years many results have not been confirmed and clinical applications are still missing. However recent findings suggest that we are at the beginning of a new era. A set of variants within neuroplasticity and inflammation genes have been identified as a valid basis for both bipolar disorder and major depression. Similarly, a set of genes has been identified as a liability factor for response and tolerability to antidepressants and the first clinical applications are already in the market...

It has been over 50 years since a review has focused exclusively on the monoamine oxidase (MAO) inhibitor tranylcypromine (TCP). A new review has therefore been conducted for TCP in two parts which are written to be read preferably in close conjunction: part I - pharmacodynamics, pharmacokinetics, drug interactions, toxicology; and part II - clinical studies with meta-analysis of controlled studies in depression, practice of TCP treatment, place in therapy. The irreversible and nonselective MAO-A/B inhibitor TCP has been confirmed as an efficacious and safe antidepressant drug...

OBJECTIVE: Conventional antidepressant treatments result in symptom remission in 30% of those treated for major depressive disorder, raising the need for effective adjunctive therapies. Inflammation has an established role in the pathophysiology of major depressive disorder, and minocycline has been shown to modify the immune-inflammatory processes and also reduce oxidative stress and promote neuronal growth. This double-blind, randomised, placebo-controlled trial examined adjunctive minocycline (200 mg/day, in addition to treatment as usual) for major depressive disorder...

We synthesized a series of aryl/heteroarylpiperazinyl derivatives of 8-acetyl-7-hydroxy-4-methylcoumarin and evaluated their antidepressant-like activity. We used a fast, microwave-assisted synthesis protocol and (1)H, (13)C NMR and HRMS spectrometry to confirm the structure of all compounds. We also used radioligand binding assays to determine the affinities towards 5-HT1A and 5-HT2A receptors and performed molecular docking studies to rationalize obtained results. Among the evaluated compounds seven displayed high affinity to the 5-HT1A (3a-1...

Antidepressant drugs such as selective serotonin reuptake inhibitors (SSRIs) specifically increase serotonin (5-HT) levels in the synaptic cleft and are widely used to treat mood and anxiety disorders. There are 14 established subtypes of 5-HT receptors in rodents, each of which has regionally different expression patterns. Many preclinical studies have suggested that the hippocampus, which contains abundant 5-HT1A and 5-HT4 receptor subtypes in the dentate gyrus (DG), is critically involved in the mechanisms of action of antidepressants...

Emerging evidence implicates impaired self-regulation of the hypothalamic-pituitary-adrenal (HPA) axis and inflammation as important and closely related components of the pathophysiology of major depression. Antidepressants show anti-inflammatory effects and are suggested to enhance glucocorticoid feedback inhibition of the HPA axis. HPA axis activity is also negatively self-regulated by the adrenocorticotropic hormone (ACTH), a potent anti-inflammatory peptide activating five subtypes of melanocortin receptors (MCRs)...

Background: Cariprazine, a D3-preferring dopamine D2/D3 receptor partial agonist, is a new antipsychotic drug recently approved in the US for the treatment of schizophrenia and bipolar mania. We recently demonstrated that cariprazine also has significant anti-anhedonic-like effects in rats subjected to chronic stress; however, the exact mechanism of action for cariprazine's antidepressant-like properties is not known. Thus, in this study we examined whether the effects of cariprazine are mediated by dopamine D3 receptors...
