INTRODUCTION: Neonatal respiratory disorders are a leading cause of perinatal mortality due to complications resulting from premature births and prenatal exposure to drugs of abuse, but optimal treatments for these symptoms are still unclear due to a variety of confounds and risk factors. Mouse models present an opportunity to study the underlying mechanisms and efficacy of potential treatments of these conditions with controlled variables. However, measuring respiration in newborn mice is difficult and commercial components are expensive and often require modification, creating a barrier and limiting our understanding of the short and long-term effects of birth complications on respiratory function...

Though commonly used as a treatment for ADHD, the psychostimulant methylphenidate (MPH) is also misused and abused in adolescence in both clinical and general populations. Although MPH acts via pathways activated by other drugs of abuse, the short- and long-term effects of MPH on reward processing in learning and decision-making are not clearly understood. We examined the effect of adolescent MPH treatment on a battery of reward-directed behaviors both in adolescence during its administration and in adulthood after its discontinuation...

The rise in popularity of substituted methcathinones (aka "bath salts") has increased the focus on their neurotoxic effects. Two commonly abused methcathinones, 3,4-methylenedioxymethcathinone (methylone, MDMC) and 3,4-methylenedioxypyrovalerone (MDPV), are often concomitantly ingested with the illicit drug 3,4-methylenedioxymethamphetamine (MDMA). To examine potential neurotoxic effects of these drug combinations, C57BL/6J mice were administered 4 i.p. injection of the drugs, at 2h intervals, either singularly: MDMA 15 or 30mg/kg, methylone 20mg/kg, MDPV 1mg/kg; or in combination: methylone/MDMA 20/15mg/kg, MDPV/MDMA 1/15mg/kg...

BACKGROUND: Estimates of economic and social costs related to alcohol and other drug (AOD) use and abuse are usually made at state and national levels. Ecological analyses demonstrate, however, that substantial variations exist in the incidence and prevalence of AOD use and problems including impaired driving, violence, and chronic disease between smaller geopolitical units like counties and cities. This study examines the ranges of these costs across counties and cities in California...

The concept of binge drinking (BD) refers to patterns of heavy episodic alcohol consumption, with BD primarily occurring among adolescents and young adults. Several official definitions of BD have been proposed, in particular by the World Health Organization, the National Institute on Alcoholism and Alcohol Abuse, and the Substance Abuse and Mental Health Services Administration. Nevertheless, none of these definitions address the psychosocial and medical consequences of the type of alcohol use seen in BD. In practice, BD can thus correspond to either hazardous or harmful use of alcohol (HUA), while the episodic nature of heavy drinking in BD means that it does not meet the criteria for 'alcohol dependence'...

The prevalence of opioid abuse in the United States has been steadily increasing over the last several years among many major demographics, including pregnant women. Rise in prenatal opioid abuse has resulted in subsequent escalation of neonatal abstinence syndrome incidence, prompting the US Congress to pass the Protecting Our Infants Act of 2015. This act specifically calls for a critical review of current treatment options for prenatal opioid abuse which may ultimately lead to the development of better therapies and a decreased incidence of neonatal abstinence syndrome...

OBJECTIVE: To evaluate exercise as a treatment for stimulant use disorders. METHODS: The STimulant Reduction Intervention using Dosed Exercise (STRIDE) study was a randomized clinical trial conducted in 9 residential addiction treatment programs across the United States from July 2010 to February 2013. Of 497 adults referred to the study, 302 met all eligibility criteria, including DSM-IV criteria for stimulant abuse and/or dependence, and were randomized to either a dosed exercise intervention (Exercise) or a health education intervention (Health Education) control, both augmenting treatment as usual and conducted thrice weekly for 12 weeks...

BACKGROUND: Preliminary studies show psychedelic compounds administered with psychotherapy are potentially effective and durable substance misuse interventions. However, little is known about the association between psychedelic use and substance misuse in the general population. This study investigated the association between psychedelic use and past year opioid use disorders within illicit opioid users. METHODS: While controlling for socio-demographic covariates and the use of other substances, the relationship between classic psychedelic use and past year opioid use disorders was analyzed within 44,000 illicit opioid users who completed the National Survey on Drug Use and Health from 2008 to 2013...

Hepatocellular carcinoma is an antecedent of liver illnesses, including viral hepatitis, alcohol abuse, or metabolic disease. Transforming growth factor-Beta (TGF-b) plays an important role in creating a favorable microenvironment for tumor cell growth via two major mechanisms: an intrinsic activity as an autocrine growth factor and an extrinsic activity by inducing microenvironment changes. Recently stem cell therapy as also been a promising and potential treatment for liver cancer and in addition signaling pathways like GF/GFR systems, SDF-1α/CXC4 ligand receptor interaction and PI3K/Akt signaling, and cytokines has been identified to regulate cell fate decisions, and can be utilized to positively influence cell therapy outcomes...

BACKGROUND AND OBJECTIVES: Methadone maintenance treatment (MMT) is the gold standard for pregnant women with opioid use disorders. Still, low birth-weights were reported, in particular of mothers who became pregnant before admission to MMT. We studied whether an escalating incentive contingency-management approach may contribute to better newborn birth-weights. METHODS: A nationwide controlled randomized trial among all Israeli methadone/buprenorphine maintenance treatment (MBMT), newly or already in treatment pregnant women was performed...

Many substances can affect the central nervous system, and may cause patients to become critically ill. Acute central neurotoxicologic syndromes associated with drugs of abuse are usually caused by an overdose of sedative-hypnotic agents (including alcohol) or opioids, withdrawal from sedative-hypnotic agents, or an overdose of anticholinergic or sympathomimetic agents. Clinical findings are often syndromic, making physical examination the most important diagnostic tool in the approach to the patient with an unknown ingestion...

Reward-related learning, including that associated with drugs of abuse, is largely mediated by the dopaminergic mesolimbic pathway. Mesolimbic neurophysiology and motivated behavior, in turn, are modulated by the circadian timing system which generates ∼24-h rhythms in cellular activity. Both drug taking and seeking and mesolimbic dopaminergic neurotransmission can vary widely over the day. Moreover, circadian clock genes are expressed in ventral tegmental area dopaminergic cells and in mesolimbic target regions where they can directly modulate reward-related neurophysiology and behavior...

BACKGROUND: With the "Baby Boomer" generation reaching older adulthood, substance abuse treatment providers find themselves needing to address the unique needs of this population. Heavy drinking in adults ages 65 and over is strongly correlated with depression, anxiety, decreased social support, and poor health. However, while alcohol misuse has been shown to be predictive of a lower quality of life in older adults, the generalizability of these findings to urban dwelling, lower socioeconomic status individuals remains unclear...

Women exhibit more rapid escalation from casual drug taking to addiction, exhibit a greater withdrawal response with abstinence, and tend to exhibit greater vulnerability than men in terms of treatment outcome. In rodents, short-term estradiol intake in female rats enhances acquisition and escalation of drug taking, motivation for drugs of abuse, and relapse-like behaviors. There is also a sex difference in the dopamine response in the nucleus accumbens. Ovariectomized female rats exhibit a smaller initial dopamine increase after cocaine treatment than castrated males...

BACKGROUND: Polyarteritis nodosa (PAN) is a systemic vasculitis involving mainly medium-sized arteries and, rarely, small-sized arteries. The diagnosis is principally based on clinical exams, biopsy of an affected organ, and/or arteriography of renal or mesenteric arteries. Once diagnosed, immunosuppressive agents, such as glucocorticoids and cyclophosphamide, are generally introduced as soon as possible. Whether spontaneous remission of PAN occurs is therefore largely unknown. PRESENTATION: We describe the case of a 51-year-old woman who presented with a 4-day-history of intense pain in her left flank, hypertension, fever, microscopic hematuria, and acute renal failure...

Chronic severe pain is treated most successfully with opioid analgesics, although the clinical use of these drugs is constrained by unwanted side effects, including the potential for abuse. GABAergic neurons are located in spinal nociceptive circuits suggesting that drugs with affinity at these receptors, including benzodiazepine-like drugs, may provide an alternative to opioids for the treatment of pain. However, systemically administered conventional benzodiazepines fail to produce antihyperalgesic effects, likely due to their concurrent sedative properties...

The VI European Guidelines for Cardiovascular Prevention recommend combining population and high-risk strategies with lifestyle changes as a cornerstone of prevention, and propose the SCORE function to quantify cardiovascular risk. The guidelines highlight disease specific interventions, and conditions as women, young people and ethnic minorities. Screening for subclinical atherosclerosis with noninvasive imaging techniques is not recommended. The guidelines distinguish four risk levels (very high, high, moderate and low) with therapeutic objectives for lipid control according to risk...
