Randomized Controlled Trial
Correlation of Subjective Effects with Systemic Opioid Exposure from Fixed-Dose Combinations of Oxycodone/Acetaminophen in Recreational Users of Prescription Drugs.
To correlate abuse-related pharmacodynamic measures and pharmacokinetic measures after administering immediate-release/extended-release and immediate-release oxycodone/acetaminophen fixed-dose combination analgesicsDesign. Randomized, double-blind, active- and placebo-controlled, 7-way crossover studySetting. Contract research organizationSubjects. Nondependent recreational users of prescription opioids. ⋯ Immediate-release/extended-release oxycodone/acetaminophen produced lower oxycodone Cmax and longer tmax than immediate-release oxycodone/acetaminophen. Lower oxycodone concentrations, particularly at earlier time points, were strongly correlated with lesser positive subjective drug effects.

Randomized Controlled Trial
Local Injection of Methylcobalamin Combined with Lidocaine for Acute Herpetic Neuralgia.
To determine the efficacy of methylcobalamin combined with lidocaine for acute herpetic neuralgia. ⋯ Local methylcobalamin combined with lidocaine, optimally administered within 4-7 days of onset, may be an effective therapeutic option for acute herpetic neuralgia.

Randomized Controlled Trial
The Association Between Parkinson's Disease Motor Impairments and Pain.
This study aimed to: 1) examine the severity and frequency of pain and the extent to which pain interferes with work and 2) explore the contributions of motor impairments to pain in people with Parkinson's disease (PD). ⋯ Most people with PD experience pain at least monthly and pain interferes with daily activities. PD impairments are associated with more frequent pain and pain that interferes with work, with rigidity having the strongest association. Development of Parkinson's disease-specific pain assessments and further investigation into the association between PD impairments and pain is warranted.

Despite unknown risks, prescription opioid use (POU) for nonmalignant chronic pain has grown in the US over the last decade. The objective of this study was to examine associations between POU and coronary heart disease (CHD), stroke, and cardiovascular disease (CVD) death in a large cohort. ⋯ Female but not male POU were at higher risk of CHD and CVD death. POU was not associated with stroke in overall or sex-stratified analyses.

Observational Study
Timeliness of Care Planning upon Initiation of Chronic Opioid Therapy for Chronic Pain.
Chronic opioid therapy (COT) guidelines recommend developing a COT care plan at the initiation of COT. ⋯ Patients initiating COT were unlikely to have timely COT care plans. Many who sustained regular opioid use at 1 year had not anticipated using opioids long term.
