Risky, non-dependent alcohol use is prevalent in the United States, affecting 25% of adults (Centers for Disease Control and Prevention, 2014b). Massachusetts has higher rates of alcohol use and binge drinking than most states (Substance Abuse and Mental Health Services Administration, 2015). Serious physical, social, and economic consequences result. Excessive alcohol use contributes to cancer, cardiovascular disease, sleep disorders, birth defects, motor vehicle injuries, and suicide, and it complicates management of chronic illnesses (Green, McKnight-Eily, Tan, Mejia, & Denny, 2016; Laramee et al...

Animal models of drug self-administration are currently the gold standard for making predictions regarding the relative likelihood that a recreational drug substance will lead to continued use and addiction. Such models have been found to have high predictive accuracy and discriminative validity for a number of drug classes including ethanol, nicotine, opioids, and psychostimulants such as cocaine and methamphetamine. Members of the entactogen class of psychostimulants (drugs that produce an "open mind state" including feelings of interpersonal closeness, intimacy and empathy) have been less frequently studied in self-administration models...

BACKGROUND: The treatment of methamphetamine dependence is a continuing global health problem. Agonist type pharmacotherapies have been used successfully to treat opioid and nicotine dependence and are being studied for the treatment of methamphetamine dependence. One potential candidate is lisdexamfetamine, a pro-drug for dexamphetamine, which has a longer lasting therapeutic action with a lowered abuse potential. The purpose of this study is to determine the safety of lisdexamfetamine in this population at doses higher than those currently approved for attention deficit hyperactivity disorder or binge eating disorder...

BACKGROUND: Opioids are recently recommended for those who do not gain adequate pain relief from the use of acetaminophen or nonsteroidal anti-inflammatory drugs. Medical opioids are administered in various routes, and transdermal opioid products that can make up for the weaknesses of the oral or intravenous products have been developed. This study is to evaluate the clinical usefulness of fentanyl matrix in terms of the long-term improvement in pain and physical and mental functions...

Pain is a significant clinical problem and there is a need for more effective treatments with reduced adverse effects that currently limit the use of mu opioid receptor agonists. Synthetic kappa opioid receptor agonists have no abuse liability and well-documented antinociceptive effects; however, adverse effects (diuresis, dysphoria) preclude their use in the clinic. Combining kappa opioids with non-opioid drugs (cannabinoid receptor agonists) allows for smaller doses of each drug to produce antinociception...

In order to describe experiences of living with opioid dependence, thirteen interviews were conducted with people participating in medication-assisted treatment. The results showed that living with opioid dependence is about the two-faced drug. The participant's past was a constant burden in life, and the drug filled a spiritual emptiness. The participant's described a life in chaos and pain, and furthermore, a life without dignity and in alienation. Opioid dependence means great suffering. Having a holistic view and by gaining an understanding of the complexities of opioid dependence, healthcare professionals can provide nonjudgmental and respectful treatment...

Herein we report the synthesis of tripodal C3-symmetric opioid scaffolds as high-affinity condensation agents of duplex DNA. Condensation was achieved on both supercoiled and canonical B-DNA structures and identified by agarose electrophoresis, viscosity, turbidity and atomic force microscopy (AFM) measurements. Structurally, the requirement of a tris-opioid scaffold for condensation is demonstrated as both di- (C2-symmetric) and mono-substituted (C1-symmetric) mesitylene-linked opioid derivatives poorly coordinate dsDNA...

OBJECTIVES: Smokers on chronic opioid therapy for non-cancer pain use prescription opioids at higher dosages and are at increased risk for opioid misuse and dependence relative to non-smokers. The current study aims to assess whether smoking is associated with problems and concerns with chronic opioid therapy from the perspective of the patient. METHODS: In a large sample (N=972) of adult patients prescribed opioids for chronic noncancer pain, we examined sex-specific associations between smoking status and patient perceptions of problems and concerns with chronic opioid therapy using regression analyses, adjusting for covariates...

Although opioids are highly efficacious analgesics, their abuse potential and other untoward side effects diminish their therapeutic utility. The addition of non-opioid analgesics offers a promising strategy to reduce required antinociceptive opioid doses that concomitantly reduce opioid-related side effects. Inhibitors of the primary endocannabinoid catabolic enzymes fatty acid amide hydrolase (FAAH) and monoacylglycerol lipase (MAGL) show opioid-sparing effects in preclinical models of pain. As simultaneous inhibition of these enzymes elicits enhanced antinociceptive effects compared with single enzyme inhibition, the present study tested whether the dual FAAH-MAGL inhibitor SA-57 [4-[2-(4-chlorophenyl)ethyl]-1-piperidinecarboxylic acid 2-(methylamino)-2-oxoethyl ester] produces morphine-sparing antinociceptive effects, without major side effects associated with either drug class...

BACKGROUND AND AIMS: Screening, brief intervention and 'referral to treatment' programs have been widely promoted as US federal policy. Little is known about the efficacy of the RT component (referral to treatment) of brief intervention for motivating patients with unhealthy drug use identified by screening to use addiction treatment. This study aimed to compare receipt of addiction treatment following two types of brief intervention for drug use vs a no-intervention control group among primary care patients screening positive for drug use...

BACKGROUND AND AIMS: The relationship between gestational age at delivery and the severity of neonatal abstinence syndrome (NAS) is poorly understood. Our objective was to compare the length of pharmacotherapy and hospital stay among opioid exposed infants born during the late preterm, early term, full term, and late term periods. DESIGN: Retrospective cohort study of infants affected by NAS SETTING: MetroHealth Medical Center in Cleveland, Ohio, USA: an urban tertiary care hospital serving as the referral center for opioid dependency in pregnancy with a level III neonatal intensive care unit PARTICIPANTS: All deliveries complicated by maternal opioid exposure from January 2000 to October 2014; 403 were eligible to be included (n = 102 Late Preterm, 34-36weeks (LP), n = 158 Early Term, 37-38weeks (ET), n = 122 Full Term, 39-40weeks (FT), n = 21 Late Term, ≥41 weeks (LT))...

In addition to dopamine neuron firing, cholinergic interneurons (ChIs) regulate dopamine release in the striatum via presynaptic nicotinic receptors (nAChRs) on dopamine axon terminals. Synchronous activity of ChIs is necessary to evoke dopamine release through this pathway. The frequency-dependence of disynaptic nicotinic modulation has led to the hypothesis that nAChRs act as a high-pass filter in the dopaminergic microcircuit. Here, we used optogenetics to selectively stimulate either ChIs or dopamine terminals directly in the striatum...

Despite recent advances in perioperative patient care, postsurgical pain continues to be undermanaged. There is increasing acceptance of the concept that effective postsurgical pain management is best achieved through combined use of more than one analgesic agent or technique, and overreliance on opioids produces unwanted side effects limiting their utility. Accordingly, a balanced, multimodal approach to pain management within the larger framework of an Enhanced Recovery After Surgery (ERAS) pathway has become standard at many institutions for perioperative care, to control postsurgical pain, reduce opioid-related adverse events, hasten postsurgical recovery, and shorten length of hospital stay...

Due to combined antiretroviral therapy (cART), human immunodeficiency virus type 1 (HIV-1) is considered a chronic disease with high prevalence of mild forms of neurocognitive impairments, also referred to as HIV-associated neurocognitive disorders (HAND). Although opiate drug use can exacerbate HIV-1 Tat-induced neuronal damage, it remains unknown how and to what extent opioids interact with Tat on the GABAergic system. We conducted whole-cell recordings in mouse striatal slices and examined the effects of HIV-1 Tat in the presence and absence of morphine (1 μM) and damgo (1 μM) on GABAergic neurotransmission...

Leishmaniasis is caused by intracellular parasites of Leishmania species, which are transmitted by the bite of the sandfly. Recovery and protection against the infection depends on the induction of a strong Th1 type of immune response. Vaccination of mice with the opioid antagonist naloxone can promote the activation of the Th1 responses. We studied the efficacy of the mixture of naloxone and alum, as an adjuvant, to enhance immune responses and induce protection against Leishmania major infection in BALB/c as a susceptible mouse model...

INTRODUCTION: A growing area of research suggests that neuroimmunity may impact the pharmacology of opioids. Microglia is a key component of the brain immunity. Preclinical and clinical studies have demonstrated that microglial modulators may improve morphine-induced analgesia and prevent the development of tolerance and dependence. Positron emission tomography (PET) using translocator protein 18kDa (TSPO) radioligand is a clinically validated strategy for the non-invasive detection of microglial activation...

The catastrophic effects of opioids use on public health and the economy are documented clearly in numerous studies. Repeated morphine administration can lead to either a decrease (tolerance) or an increase (sensitization) in its behavioral and rewarding effects. Morphine-induced sensitization is a major problem and plays an important role in abuse of the opioid drugs. Studies reported that morphine may exert its effects by the release of nitric oxide (NO). NO is a potent neuromodulator, which is produced by nitric oxide synthase (NOS)...
