REVIEW
Wendy M Bosker, Irene Neuner, N Jon Shah
Drug addiction is a debilitating disorder and its pivotal problem is the high relapse rate. To solve this problem, the aim is to prevent people from becoming addicted in the first place. One of the key questions that is still unanswered is why some people become addicted to drugs and others, who take drugs regularly, do not. In recent years extensive research has been done to untangle the many factors involved in this disorder. Here, we review some of the factors that are related to dopamine, i.e., impulsivity and stress (hormones), and aim to integrate this into a neurobiological model...

Purpose Blockade of the programmed cell death 1 (PDCD1, PD-1) immune checkpoint pathway can improve clinical outcomes in various malignancies. Evidence suggests that aspirin (a widely used nonsteroidal anti-inflammatory drug) not only prolongs colorectal cancer survival, but can also activate T cell-mediated antitumor immunity and synergize with immunotherapy through inhibition of prostaglandin E2 production. We hypothesized that the survival benefit associated with aspirin might be stronger in colorectal carcinoma with a lower CD274 (PDCD1 ligand 1, PD-L1) expression level that resulted in lower signaling of the immune checkpoint pathway...

Background: Recent data suggest that the use of nonsteroidal anti-inflammatory drugs (NSAIDs) may be associated with reductions in endometrial cancer risk, yet very few have examined whether their use is related to prognosis among endometrial cancer patients. Methods: Study subjects comprised 4374 participants of the NRG Oncology/Gynecology Oncology Group 210 Study with endometrial carcinoma who completed a presurgical questionnaire that assessed history of regular prediagnostic NSAID use and endometrial cancer risk factors...

BACKGROUND: Nonsteroidal anti-inflammatory drugs (NSAIDs) have been associated with improved survival in some cancers, but evidence for ovarian cancer is limited. METHODS: Pooling individual-level data from 12 Ovarian Cancer Association Consortium studies, we evaluated the association between self-reported, pre-diagnosis use of common analgesics and overall/progression-free/disease-specific survival among 7694 women with invasive epithelial ovarian cancer (4273 deaths)...

BACKGROUND: Previous studies demonstrated increased risk of cataract development among users of selective serotonin reuptake inhibitors (SSRIs). However, it remains unknown whether this risk also prevails with the use of other types of antidepressants. The aim of this study was to investigate whether use of antidepressants is associated with an increased risk of cataract development. Moreover, the relationship between binding affinities of serotonin transporter (SERT) of antidepressant and the risk of cataracts is examined...

Objective There are contrasting positions concerning the benefit-risk ratio of acetaminophen use for osteoarthritis (OA)-related pain. To clarify the effectiveness of acetaminophen or acetaminophen-codeine combinations according to their regimen of use, we evaluated whether being a regular user (adherent) of these medications decreased the occurrence of rescue therapy with non-steroidal anti-inflammatory drugs (NSAIDs). Methods Using the Health Search IMS Health Longitudinal Patient Database, we formed a cohort of patients aged ≥18 years and newly treated with acetaminophen or acetaminophen-codeine combinations for OA between January 1, 2001 and December 31, 2013...

INTRODUCTION AND AIMS: The extent to which young adult former cannabis users fare better than infrequent users is unclear. We investigated the association between cannabis use status at age 23 and substance use and mental health outcomes at age 27. DESIGN AND METHODS: Data were from the 20+ year cohort of the PATH Through Life Study. Lifetime cannabis users (n = 1410) at age 23 were classified as former/occasional/regular users. Multivariable logistic regression was used to estimate the association between cannabis use status at age 23 and six outcomes assessed at age 27...

People who use drugs (PWUDs) are at increased risk for several medical conditions, yet they delay seeking medical care and utilize emergency departments (EDs) as their primary source of care. Limited research regarding perceived discrimination and PWUDs' use of health care services exists. This study explores the association between interpersonal and institutional racial/ethnic and drug use discrimination in health care settings and health care utilization among respondents (N = 192) recruited from methadone maintenance treatment programs (36%), HIV primary care clinics (35%), and syringe exchange programs (29%) in New York City (n = 88) and San Francisco (n = 104)...

PURPOSE: The aim of this observational cohort study was to investigate blood pressure level and the possibility to reach target blood pressure during concomitant use of NSAID in hypertensive patients. MATERIALS AND METHODS: From the Swedish primary care cardiovascular database (SPCCD) a cohort of 5463 patients (2007 to 2008) with at least one prescription of NSAID dispensed 6 months prior to the last blood pressure measurement were included. Clinical data were extracted from computerized medical records and linked to the Prescribed Drug Register...

With several states allowing medicinal use of marijuana and a growing number decriminalizing recreational use, many of our patients are using this herbal drug. Approximately 43% of US adults have tried marijuana, with 13% using it regularly. These users are seeking help from integrative medicine practitioners regarding safety. They are looking for advice based on research and clinical experience, not politics or philosophical bias. The major health problems caused by marijuana appear to be bronchial irritation, decreased motivation, learning difficulties, and injuries...

BACKGROUND: Examine the motivations for new psychoactive substance (NPS) use amongst a sample of regular psychostimulant users (RPU) in Australia, and determine whether motivations differ across substances. METHOD: Data were obtained from 419 RPU interviewed for the 2014 Ecstasy and related Drugs Reporting System who reported lifetime NPS use. Based on the most recent NPS used, motivations for use were rated on an 11-point scale (0 'no influence'-10 'maximum influence')...

To investigate the prevalence and the associated risk factors of human immunodeficiency virus (HIV), hepatitis B virus (HBV) and sexually transmitted infections (STIs) among men who have sex with men (MSM) in Kunming, 300 MSM were recruited through community-based organizations between September 2014 and January 2015. The prevalence of HIV, HBsAg, syphilis, Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) were 17.0%, 7.7%, 11.3%, 18.2% and 13.2%, respectively. In the three different anatomic sites (urethra, rectum and pharynx), the prevalence of rectal CT was the highest (15...

OBJECTIVE: This analysis examined alcohol and drug use over a 6-year follow-up of children in the Longitudinal Assessment of Manic Symptoms (LAMS) study. METHOD: LAMS screened 6- to 12.9-year-old children visiting 9 child outpatient mental health (MH) clinics, using the Parent General Behavior Inventory 10-item mania scale. All children with scores ≥12 and a matched group with scores ≤12 were invited to enroll. Children were assessed every 6 months. Assessments included demographics, family, MH history, child diagnoses, child stress, and alcohol and drug use...

OBJECTIVE: Assess willingness to use HIV pre-exposure prophylaxis (PrEP), support for others using it and willingness to have sex with partners using PrEP among Australian gay and bisexual men (GBM). METHODS: National, online cross-sectional surveys of Australian GBM were conducted in 2011, 2013 and 2015. Scales measuring support for and willingness to have sex with men using PrEP were developed in 2015 using factor analysis. Trends and associations with key measures were analysed using multivariate logistic regression...

The Chinese government has come under attack by international critics for forcing drug users to labor in the name of treatment. While joining these activists in criticizing conditions in compulsory labor centers, former detainees who congregated at a drop-in center in southern Yunnan also defended the therapeutic potential of socialist legacies of laboring. Shuttling between laboring in state compulsory centers and idling in a market economy, long-term heroin users saw their difficulties in recovering from addiction as inextricably linked to their inability to find suitable work opportunities...
