Low-grade inflammation is a risk factor for depression, psychosis and other major psychiatric disorders. It is associated with poor response to antidepressant and antipsychotics, and could potentially be a treatment target. However, there is limited data on the prevalence of low-grade inflammation in major psychiatric disorders, and on the characteristics of patients who show evidence of inflammation. We examined the prevalence of low-grade inflammation and associated socio-demographic and clinical factors in acute psychiatric inpatients...

BACKGROUND: Prolonged treatment with benzodiazepines is common practice despite clinical recommendations of short-term use. Benzodiazepines are used by approximately 4% of the general population, with increased prevalence in psychiatric populations and the elderly. After long-term use it is often difficult to discontinue benzodiazepines due to psychological and physiological dependence. This review investigated if pharmacological interventions can facilitate benzodiazepine tapering. OBJECTIVES: To assess the benefits and harms of pharmacological interventions to facilitate discontinuation of chronic benzodiazepine use...

Nitrazolam and clonazolam are two designer benzodiazepines that are available from internet retailers and there is growing evidence suggesting that such compounds have the potential to cause severe adverse events. Information about tolerability in humans is scarce but typically, low doses can be difficult to administer for users when handling bulk material and variability of the active ingredient in tablet formulations can also be of a concern. Customs, toxicology and forensic laboratories are increasingly encountering designer benzodiazepines, both in tablet and powdered forms, and the unavailability of reference standards can impact on the ability to identify these compounds...

OBJECTIVES: propofol is a rapid acting hypnotic that is becoming the drug of choice for sedation in digestive endoscopy worldwide. There is some controversy with regard to the use of propofol by physicians who are not anesthesiologists. We present our experience of the administration of propofol by endoscopist and nursing personnel. METHODS: this was a retrospective study of sedation in endoscopy. Propofol was exclusively used and administered by the endoscopist who performed the procedure and the nursing staff...

PURPOSE: Whereas SPECT images obtained 180 minutes after administration of I-iomazenil (IMZ) (late images) are proportional to the distribution of central benzodiazepine receptor-binding potential, SPECT images obtained within 30 minutes after I-IMZ administration (early images) correlate with regional brain perfusion. The aim of the present study was to determine whether crossed cerebellar tracer uptake on acute-stage I-IMZ SPECT imaging predicts 3-month functional outcome in patients with nonfatal hypertensive putaminal or thalamic hemorrhage...

Gabapentin has become increasingly used in psychiatric practice specifically for anxiety disorders. Even though gabapentin is not approved by the US Food and Drug Administration to treat anxiety, physicians sometimes use it as an alternative to benzodiazepines in patients with a history of substance abuse. Gabapentin is also prescribed when individuals are at risk of thrombocytopenia which is not considered a side effect. Among patients at risk of thrombocytopenia are those positive for human immunodeficiency virus (HIV)...

The benzodiazepine benzomalvin A/D is a fungal-derived specialized metabolite and inhibitor of the substance P receptor NK1, biosynthesized by a three-gene non-ribosomal peptide synthetase cluster. Here, we utilize <u>f</u>ungal <u>a</u>rtificial <u>c</u>hromosomes with <u>m</u>etabolomic <u>s</u>coring (FAC-MS) to carry out molecular genetic pathway dissection and targeted metabolomics analysis to assign the in vivo role of each domain in the benzomalvin biosynthetic pathway...

The U.S. Environmental Protection Agency's ToxCast program has screened thousands of chemicals for biological activity, primarily using high-throughput in vitro bioassays. Adverse outcome pathways (AOPs) offer a means to link pathway-specific biological activities with potential apical effects relevant to risk assessors. Thus, efforts are underway to develop AOPs relevant to pathway-specific perturbations detected in ToxCast assays. Previous work identified a 'cytotoxic burst' (CTB) phenomenon wherein large numbers of the ToxCast assays begin to respond at or near test chemical concentrations that elicit cytotoxicity, and a statistical approach to defining the bounds of the CTB was developed...

OBJECTIVES: The occurrence of depression in people with epilepsy is almost twice as common as in the general population. Furthermore, depression is the first cause of lower quality of life among those patients. Which is why the main goal of this study was to assess the epidemiology of depression and its associated factors among the patients from the tertiary department of epileptology in Rennes. METHODS/RESULTS: The subjects were included prospectively and consecutively at the moment of their consultation or hospitalisation in the department...

BACKGROUND: Higher levels of drug use have been reported in lesbian, gay, bisexual and transgender (LGBT) communities, some of which can be explained by sexualised drug use, including 'chemsex'; the use of drugs before or during planned sexual activity to sustain, enhance, disinhibit or facilitate sex. We explored injecting and non-injecting drug use by sexual behaviour among people who inject drugs (PWID) in England, Wales and Northern Ireland. METHODS: Data were used from an unlinked-anonymous survey of PWID (2013-2016), where participants recruited through services self-completed a questionnaire...

Toxic exposures with serious outcomes have increased over the last decade. Limited data exists on the pattern and outcomes of overdose-exposure patients requiring intensive care unit (ICU) admission. The primary objective of this study was to characterize the causes, treatments, and outcomes of toxic exposures in a mid-sized Midwestern health system. The secondary objective was to report cumulative economic costs associated with these patients. Data were obtained from medical records of patients 18 years or older with a diagnosis code of overdose admitted to the ICU at 2 teaching hospitals between August 1, 2012, and July 31, 2014...

BACKGROUND AND PURPOSE: The pathophysiological role of α6 subunit-containing GABAA receptors (α6GABAA Rs), which are mainly expressed in cerebellar granule cells, remains unclear. Recently, we demonstrated that hispidulin, a flavonoid isolated from a local herb that remitted a patient's intractable motor tics, attenuated methamphetamine-induced hyperlocomotion in mice as a positive allosteric modulator (PAM) of cerebellar α6GABAA Rs. Here, using hispidulin and a selective α6GABAA R PAM, the pyrazoloquinolinone Compound 6, we revealed an unprecedented role of cerebellar α6GABAA Rs in disrupted prepulse inhibition (PPI), which reflects sensorimotor gating deficits manifested in several neuropsychiatric disorders...

Midazolam, a benzodiazepine derivative, is widely used for sedation and surgery. However, previous studies have demonstrated that Midazolam is associated with increased risks of congenital malformations, such as dwarfism, when used during early pregnancy. Recent studies have also demonstrated that Midazolam suppresses osteogenesis of mesenchymal stem cells (MSCs). Given that hypertrophic chondrocytes can differentiate into osteoblast and osteocytes and contribute to endochondral bone formation, the effect of Midazolam on chondrogenesis remains unclear...
