Hundreds of new psychoactive substances (NPS) have emerged in the drug market over the last decade. Few drug surveys in the USA, however, ask about use of NPS, so prevalence and correlates of use are largely unknown. A large portion of NPS use is unintentional or unknown as NPS are common adulterants in drugs like ecstasy/Molly, and most NPS are rapidly eliminated from the body, limiting efficacy of urine, blood and saliva testing. We utilized a novel method of examining prevalence of NPS use in a high-risk population utilizing hair-testing...

BACKGROUND: Dabigatran is prescribed to increasing numbers of patients with atrial fibrillation (AF). Although routine monitoring is not considered to be useful, measuring drug concentrations can be clinically relevant in specific situations. The aim of this study was the comparison of different functional and non-functional assays for determination of dabigatran concentrations at different timepoints in a real-life patient population with AF. We focused on the differences between assays in identifying patients with low drug concentrations...

Sleep disturbance contributes to impaired procedural learning in schizophrenia, yet little is known about this relationship prior to psychosis onset. Adolescents at ultra high-risk (UHR; N=62) for psychosis completed the Pittsburgh Sleep Quality Index (PSQI) and a procedural learning task (Pursuit Rotor). Increased self-reported problems with sleep latency, efficiency, and quality were associated with impaired procedural learning rate. Further, within-sample comparisons revealed that UHR youth reporting better sleep displayed a steeper learning curve than those with poorer sleep...

The auditory mismatch negativity (MMN) is a component of event-related potentials, which is being increasingly recognized as a candidate biomarker for early stages of psychosis. Although previous cross-sectional studies have demonstrated small MMN amplitude in early stages of psychosis, it remains unknown whether small MMN amplitude is due to progressive reduction during the early course. In this study, we investigated longitudinal changes of MMN in early stages of psychosis. Participant included 14 patients with first-episode psychosis (FEP), 16 individuals with ultra-high risk (UHR), and 16 healthy control subjects (HC)...

Anabolic and androgenic steroids (AASs) are a class of prohibited substances banned in horseracing at all times. The common approach for controlling the misuse of AASs in equine sports is by detecting the presence of AASs and/or their metabolites in urine and blood samples using gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS). This approach, however, often falls short as the duration of effect for many AASs are longer than their detection time in both urine and blood...

BACKGROUND/OBJECTIVES: Cardiovascular disease (CVD) remains a major cause of death worldwide. Whereas dairy generally is associated with a neutral or a beneficial CVD effect, the consumption of ultra-high temperature (UHT)-treated milk has been reported to increase levels of low-density lipoprotein cholesterol (LDL-C) in an uncontrolled study. Our aim was to examine whether semi-skimmed UHT dairy milk increases the risk of CVD development compared with pasteurized (PAST) dairy milk in overweight healthy adults...

Magnetic resonance imaging (MRI) has become a promising technique in the early diagnosis of cancers, especially the application of contrast agents can further enhance the detection limitation. Compared with the dark signal in "negative" contrast agents (T2), "positive" contrast agents (T1) with bright signal are more desirable for high-resolution imaging. However, the clinical used gadolinium complexes have short circulation time and the risk of nephrogenic system fibrosis. Therefore, to overcome the disadvantage of T2 agents and traditional T1 agents, it is very interesting to develop nano-scaled T1-weighted MRI contrast agents with safer and more precise imaging performance...

Ceftriaxone is a cephalosporin antibiotic with a potent antimicrobial activity and excellent penetration in most body fluids such as pleural, peritoneal, spinal and brain. These facts contribute to the application of ceftriaxone in the treatment of bacterial peritonitis, an abdominal disorder in veterinary medicine, with potential risk of death. The determination of ceftriaxone levels in plasma and peritoneal fluid may be used to assess the pharmacokinetic profile at various instances of administration and allows observing if the concentrations needed are being achieved...

Telomere length attrition has been demonstrated in schizophrenia but not in individuals in ultra high risk (UHR) for psychosis. The present study aimed to compare the leukocyte telomere length (TL) between patients at UHR for psychosis and healthy controls (HC). Twenty-two participants with UHR and 88 HC were enrolled in this study. Telomere lengths were determined using a multiplex qPCR assay. After adjustment for age, sex, ethnicity, and education, patients in UHR, compared with HC groups, had shorter telomere length (RR: 0...

A need for a brief, easy to complete self-report questionnaire to detect people at ultra-high risk for psychosis (UHR) in busy clinical settings has been recognised. Our aim was to explore whether the Community Assessment of Psychic Experiences - Positive 15-items Scale (CAPE-P15) could be used as a screening tool to identify people at UHR in a clinical setting. Our objectives were to confirm the CAPE-P15 factorial structure as well as its reliability and determine cut-off values for the detection of such individuals using the Comprehensive Assessment of At-Risk Mental States (CAARMS), a commonly used clinical interview for the detection of UHR...

Algae dietary supplements are marketed worldwide as natural health products. Although their proprieties have been claimed as beneficial to improve overall health, there have been several previous reports of contamination by cyanotoxins. These products generally contain non-toxic cyanobacteria, but the methods of cultivation in natural waters without appropriate quality controls allow contamination by toxin producer species present in the natural environment. In this study, we investigated the presence of total microcystins, seven individual microcystins (RR, YR, LR, LA, LY, LW, LF), anatoxin-a, dihydroanatoxin-a, epoxyanatoxin-a, cylindrospermopsin, saxitoxin, and β-methylamino-l-alanine in 18 different commercially available products containing Spirulina or Aphanizomenon flos-aquae...

Diffusion parameters of brain tracts (n=18) were studied in 27 men with ultra-high risk of endogenous attack-like psychoses and 27 mentally healthy men of the same age group (fractional anisotropy; and average, radial, and axial diffusion). Correlation analysis was performed between these parameters and severity of mental disorders (SOPS scale). The indexes of radial diffusion and axial diffusion were shown to change in the left anterior thalamic radiation and right posterior cingulum bundle, respectively. Our results are consistent with published data that disturbances in the frontal and temporal lobes play an important role in the pathogenesis of schizophrenia...
