BACKGROUND: Although people who use drugs (PWUD) are key populations recommended to receive pre-exposure prophylaxis (PrEP) to prevent HIV, few data are available to guide PrEP delivery in this underserved group. We therefore examined the willingness to initiate PrEP and the anticipation of HIV risk reduction while on PrEP among high-risk PWUD. METHODS: In a cross-sectional study of 400 HIV-negative, opioid dependent persons enrolled in a methadone program and reporting recent risk behaviors, we examined independent correlates of being willing to initiate PrEP...

Since the 1990s, the use of prescription opioids has largely spread, which has brought a real progress in the treatment of pain. The long-term use of prescription opioid is sometimes required, and may lead to pharmacological tolerance and withdrawal symptoms, i.e. pharmacological dependence on prescription opioids. Occasionally, this may also lead to misuse of prescription opioids (MPO). MPO preferentially occurs in vulnerable individuals, i.e., those with a young age, history of other addictive or psychiatric disorders, especially anxious and depressive disorders...

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...

The photochemical transformation of pharmaceutical and personal care products (PPCPs) in wastewater effluents is an emerging concern for environmental scientists. In the current study, the photodegradation of 29 PPCPs was examined in effluents under simulated solar irradiation. Direct photodegradation, triplet state effluent organic matter (3EfOM*)-mediated and hydroxyl radical (HO•)-mediated degradation are three major pathways in the removal process. With the photodegradation of trace levels of PPCPs, the excitation-emission matrix (EEM) fluorescence intensities of the effluents were also gradually reduced...

BACKGROUND: Since 2003, a harm reduction program for injecting drug users has been rolled out countrywide in China. It entails services for condom promotion, a needle and syringe program (NSP), and methadone maintenance treatment (MMT). However, it remains unknown if and to what extent the coverage of these services at city level is related to a reduced risk of HIV infection among drug users. METHODS: We wished to quantify the extent to which city-level characteristics (such as NSP and MMT service coverage) and individual-level determinants (e...

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...

REVIEW
Lori Keough, Heidi Collins Fantasia
Opioid addiction during pregnancy presents a treatment challenge to clinicians and women alike. Untreated addiction can lead to poor maternal and fetal health outcomes. Medication-assisted treatment is the standard of care, and methadone is the current drug of choice for treatment. Emerging evidence also supports the use of buprenorphine during pregnancy. Both methadone and buprenorphine have risks and benefits that should be explored before initiating treatment. Clinicians who work in obstetrics and in addiction treatment can collaborate and coordinate treatment to ensure optimal maternal and fetal outcomes...

BACKGROUND: Methadone (ME) is commonly used in pain and palliative care (PPC) patients with refractory pain or intolerable opioid adverse effects (AEs). A unique ME AE is its corrected QT (QTc) interval prolongation risk, but most evidence exists in methadone maintenance therapy patients. OBJECTIVE: Our goal was to identify QTc interval prolongation risk factors in PPC patients receiving ME and other medications known to prolong the QTc interval and develop a risk stratification tool...

George E Woody
The development of medications for treating persons with opioid use disorders has expanded the number of evidence-based treatment options, particularly for persons with the most severe disorders. It has also improved outcomes compared to psychosocial treatment alone and expanded treatment availability by increasing the number of physicians involved in treatment and the settings where patients can be treated. The medications include methadone, buprenorphine, buprenorphine/naloxone, and extended-release injectable naltrexone...

Chronic use of opioid medications has been reported to cause altered sexual function. It is not known if non-opioid pain medications have similar effects. Assessment of this effect through the measurement of concentrations of free hormones is limited. Positivity of opioid medications (hydrocodone, oxycodone, morphine, methadone, tramadol and fentanyl) and non-opioid pain medications (gabapentin or pregabalin) in human serum and plasma samples from adult men and women were evaluated for association with concentrations of free testosterone (fTe) and free estradiol (fE2) measured using equilibrium dialysis-liquid chromatography-tandem mass spectrometry methods...
