BACKGROUND: The validity and concordance of two main measures of drug use behavior, self-report and urinalysis, has long been discussed. More understanding is needed about the underlying factors associated with discordance between these two methods. OBJECTIVES: Describe the pattern and associated factors of discordance between self-reported heroin use and the urinalysis results of opiate use among methadone maintenance therapy (MMT) patients in China. METHODS: A total of 2,448 MMT patients from 68 clinics in five provinces of China participated in a survey, which collected information on demographics, drug use and MMT-related factors, depressive symptoms, and drug avoidance self-efficacy...

In Vietnam's concentrated HIV epidemic, female sex workers (FSWs) are at increased risk for acquiring and transmitting HIV, largely through their male clients. A high proportion of males in Vietnam report being clients of FSWs. Studying HIV-related risk factors and prevalence among male clients is important, particularly given the potential for male clients to be a 'bridge' of HIV transmission to the more general population or to sex workers. Time-location sampling was used to identify FSW in Hanoi and Ho Chi Minh City, Vietnam's largest cities, in 2013-2014...

Stressful events and exposure to opiates during gestation have important effects on the later mental health of the offspring. Anxiety is among the most common mental disorders. The present study aimed to identify effects of prenatal restraint stress and morphine co-administration on plasma vasopressin concentration (PVC) and anxiety behaviors in rats. Pregnant rats were divided into four groups (n = 6, each): saline, morphine, stress+saline and stress+morphine treatment. The stress procedure consisted of restraint twice per day, two hours per session, for three consecutive days starting on day 15 of pregnancy...

BACKGROUND: For most physicians, quantification of drug-specific immunoglobulin E (drug-sIgE) antibodies constitutes the primary in vitro measure to document immediate drug hypersensitivity reactions (IDHR). Unfortunately, this is often insufficient to correctly identify patients with IgE-mediated IDHR and impossible for non-IgE-mediated IDHR that result from alternative routes of basophil and mast cell activation. In these difficult cases, diagnosis might benefit from cellular tests such as basophil activation tests (BAT)...

The evaluation of drug and alcohol abuse is a major subject of forensic toxicology. Assessment of drug abstinence currently requires the analysis of urine or hair. In the present study cerumen, a mixture of sebum and sweat, was tested as an alternative. Postmortem samples (blood, urine, hair and cerumen from 38 corpses) were analyzed using liquid chromatography and gas chromatography, each coupled to mass spectrometry (LC-MS, GC-MS). The results were compared. In all cases of recent drug use (i.e. detection of opiates, amphetamine and derivatives, cocaine, methadone and diazepam or their metabolites in blood) the corresponding cerumen was positive...

The primary functions of adrenal medullary chromaffin cells are the synthesis and storage in their chromaffin vesicles of the catecholamines noradrenaline (NA) and adrenaline (AD), and their subsequent release into the bloodstream by Ca(2+) -dependent exocytosis under conditions of fear or stress (fight or flight response). Several monoamines, nucleotides and opiates, such as leucine-enkephalin (LENK) and methionine-enkephalin (MENK), are also co-stored and co-released with the catecholamines. However, other neurotransmitters have not been studied in depth...

BACKGROUND & AIMS: Sleep disturbances are common in patients with cirrhosis, but their determinants and effects on health-related quality of life are not well understood. We investigated the prevalence of disturbed sleep in these patients, factors associated with sleep disruption, and effects on quality of life. METHODS: We performed a prospective, cross-sectional study of 193 stable ambulatory patients with cirrhosis (154 with decompensated cirrhosis). Participants completed the Pittsburgh sleep questionnaire index (to assess sleep quality), the chronic liver disease questionnaire (CLDQ), muscle cramp questionnaires, and underwent neurocognitive testing...

Prolactin secreting pituitary adenomas (prolactinomas) is the most common pituitary tumors in humans. Animal studies have identified aggressive prolactinoma development in fetal alcohol exposed rats. We have recently identified a combination treatment of a μ opioid receptor antagonist naltrexone and a δ opioid receptor agonist D-Ala2-,N-Me-Phe4,Gly-ol Enkephalin (DPDPE) increases innate immune function. In this study, we tested whether naltrexone and DPDPE combination therapy is useful to control pituitary tumor growth...

Background Interference from opiates in the Microgenics CEDIA(®) Buprenorphine assay is known to produce false positive buprenorphine screening immunoassay results necessitating confirmatory buprenorphine testing by chromatography/mass spectrometry methods. Method We reviewed data on falsely positive buprenorphine immunoassay screen (cut-off ≥ 5µg/L) but negative for buprenorphine by GCMS (cut-off ≥ 5µg/L) and had a positive opiate immunoassay result (cut-off ≥ 300µg/L). Results were collected over 3 months and the data were evaluated to determine whether there is an opiate immunoassay screen concentration below which a false positive buprenorphine result will not occur...

Currently, hair can be reliably tested for the presence of drugs. However, one major drawback to the use of parent drugs is the question of potential external or environmental contamination. The analysis of metabolites to confirm the use of the parent drugs was proposed in this short review. The development of hair as a test matrix and the incorporation of xenobiotics, in general, into the hair matrix were discussed. What constitutes an appropriate metabolite for drug testing to mirror the use of a parent drug was proposed and discussed...

OBJECTIVE: HIV type-1 (HIV-1) causes a spectrum of central nervous system (CNS) complications; many are worsened by opiate co-exposure. Human neural progenitor cells (hNPCs) give rise to all CNS neurons and macroglia. We tested the hypothesis that hNPC maturation and fate are altered by HIV and opiates, contributing to HIV-1-related neuropathology. Reports of hNPC infection remain controversial. We rigorously examined this question, testing whether hNPCs propogated infection, and whether HIV affected hNPCs absent their infection...

BACKGROUND: Postoperative pain after total knee arthroplasty (TKA) can be burdensome. Multiple methods of pain control have been used, including adductor canal block (ACB) and multimodal periarticular analgesia (MPA). These two techniques have been studied have proven to be efficacious separately. The purpose of this study was to compare: (1) lengths of stay (LOS), (2) pain level, (3) discharge status, and (4) opioid use in TKA patients who received ACB alone vs patients who received ACB and MPA...

Based on structure activity analysis of morphine related opiates, we have synthesized some novel benzopyran fused isoxazolidines (2a-e) and derived conformationally constrained β(2,3,3)-amino alcohols (3a-e), which were evaluated in vivo for their anti-nociceptive activity through acetic acid induced writhing test (peripheral) and formalin induced algesia (central). Results showed that, compound 2a possesses significant opioid agonist activity. Further, molecular docking analysis reveals that compound 2a binds to δ-opioid receptor (DOR) with comparatively better D-score than to μ (MOR) and κ (KOR) receptors...
