Cannabis use frequency and pain interference among people with HIV.

Cannabis is often used by people with HIV (PWH) for pain, yet study results are inconsistent regarding whether and how it affects pain. This study examines whether greater cannabis use frequency is associated with lower pain interference and whether cannabis use modifies the association of pain severity and pain interference among 134 PWH with substance dependence or a lifetime history of injection drug use. Multi-variable linear regression models examined the association between past 30-day cannabis use frequency and pain interference.

Genome-wide association study of phenotypes measuring progression from first cocaine or opioid use to dependence reveals novel risk genes.

Aim: Substance use disorders (SUD) result in substantial morbidity and mortality worldwide. Opioids, and to a lesser extent cocaine, contribute to a large percentage of this health burden. Despite their high heritability, few genetic risk loci have been identified for either opioid or cocaine dependence (OD or CD, respectively).

Alcohol and Bone Turnover Markers among People Living with HIV and Substance Use Disorder.

Background: Although unhealthy alcohol use and low bone density are prevalent among people living with HIV (PLWH), it is not clear whether alcohol use is associated with bone turnover markers (BTMs), and if so, at what quantity and frequency. The study objective was to examine the association between alcohol and BTMs in PLWH with substance use disorder.

Methods: We studied a prospective cohort recruited from 2 HIV clinics who met criteria for DSM-IV substance dependence or reported ever injection drug use.

Polypharmacy and risk of falls and fractures for patients with HIV infection and substance dependence.

Although people with HIV infection (PLWH) are at higher risk of polypharmacy and substance use, there is limited knowledge about potential harms associated with polypharmacy such as falls and fractures in this population. The study objective was to determine whether polypharmacy, as measured by the number and type of medication, is associated with falls and fractures among PLWH and DSM-IV substance dependence in the past year or ever injection drug use (IDU). We identified the number of medications by electronic medical record review in the following categories: (i) systemically active, (ii) non-antiretroviral (non-ARV), (iii) sedating, (iv) non-sedating as well as any opioid medication and any non-opioid sedating medication.

Polypharmacy and risk of non-fatal overdose for patients with HIV infection and substance dependence.

Introduction: People living with HIV (PLWH) are at risk of both polypharmacy and unintentional overdose yet there are few data on whether polypharmacy increases risk of overdose. The study objective was to determine if the number and type of medication (e.g.

Influence of statin therapy at time of stroke onset on functional outcome among patients with atrial fibrillation.

Background: Statin pretreatment has been associated with reduced infarct volume in nonlacunar strokes. The effect of statins on functional outcomes of strokes related to atrial fibrillation (AF) is unknown. We aimed to define the influence of prestroke statin use on functional outcome in AF.

Receipt of addiction treatment as a consequence of a brief intervention for drug use in primary care: a randomized trial.

Background And Aims: Screening, brief intervention and 'referral to treatment' programs have been promoted widely 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 versus a no-intervention control group among primary care patients screening positive for drug use.
