Laboratory-induced cue reactivity among individuals with prescription opioid dependence.
Addict Behav. 2014 Aug;39(8):1217-23.
Back SE, Gros DF, McCauley JL, Flanagan JC, Cox E, Barth KS, Brady KT.

Prescription opioid (PO) dependence is a critical health problem. Although examination of drug cue reactivity paradigms has advanced the understanding of risk factors for relapse for a variety of substances (e.g., cocaine, alcohol, nicotine), no PO specific drug cue paradigm has been developed. The current study addressed this gap in the literature and evaluated the ability of a newly developed PO drug cue paradigm to elicit subjective, physiological, and neuroendocrine changes among PO-dependent participants (n=20) as compared to controls (n=17). The drug cue paradigm included an induction script, viewing and handling paraphernalia (e.g., bottle of oxycontin pills, pill crusher) and watching a video depicting people using POs as well as places related to POs (e.g., pharmacies). Consistent with hypotheses, the PO group demonstrated significant pre- to post-cue increases on subjective ratings of craving, difficulty resisting POs, stress, and anger. The control group did not demonstrate significant changes on any of the subjective measures. Both the PO group and the control group evidenced significant pre- to post-cue increases in physiological responses (e.g., blood pressure, skin conductance), as expected given the arousing nature of the drug cue stimuli. The PO group, but not the control group, evidenced a significant pre- to post-cue increase in heart rate and salivary cortisol levels. The development and validation of a drug cue paradigm for POs may help inform future research and treatment development efforts for patients with PO dependence.


Management of postpartum depression.
J Midwifery Womens Health. 2013 Nov-Dec;58(6):643-53.

The mainstays of treatment for peripartum depression are psychotherapy and antidepressant medications. More research is needed to understand which treatments are safe, preferable, and effective. Postpartum depression, now termed peripartum depression by the DSM-V, is one of the most common complications in the postpartum period and has potentially significant negative consequences for mothers and their families. This article highlights common clinical challenges in the treatment of peripartum depression and reviews the evidence for currently available treatment options. Psychotherapy is the first-line treatment option for women with mild to moderate peripartum depression. Antidepressant medication in combination with therapy is recommended for women with moderate to severe depression. Although pooled case reports and small controlled studies have demonstrated undetectable infant serum levels and no short-term adverse events in infants of mothers breastfeeding while taking sertraline (Zoloft) and paroxetine (Paxil), further research is needed including larger samples and long-term follow-up of infants exposed to antidepressants via breastfeeding controlling for maternal depression. Pharmacologic treatment recommendations for women who are lactating must include discussion with the patient regarding the benefits of breastfeeding, risks of antidepressant use during lactation, and risks of untreated illness. There is a growing evidence base for nonpharmacologic interventions including repetitive transcranial magnetic stimulation, which may offer an attractive option for women who wish to continue to breastfeed and are concerned about their infants being exposed to medication. Among severe cases of peripartum depression with psychosis, referral to a psychiatrist or psychiatric advanced practice registered nurse is warranted. Suicidal or homicidal ideation with a desire, intent, or plan to harm oneself or anyone else, including the infant, is a psychiatric emergency, and an evaluation by a mental health professional should be conducted immediately. Peripartum depression treatment research is limited by small sample sizes and few controlled studies. Much work is still needed to better understand which treatments women prefer and are the most effective in ameliorating the symptoms and disease burden associated with peripartum depression.


Yohimbine administration and cocaine cue-reactivity in cocaine-dependent individuals.
Moran-Santa Maria MM, McRae-Clark A, Baker NL, Ramakrishnan, Brady KT. (2014. In press).
Psychopharmacology. NIHMSID: NIHMS583711

RATIONALE: Preclinical studies suggest that stress potentiates cue-induced cocaine seeking and that this effect is more pronounced in females. These findings have not been characterized in clinical populations. OBJECTIVES: The objectives of this study were to examine the impact a pharmacological stressor, alpha-2 adrenergic receptor antagonist yohimbine, on the subjective, endocrine, and physiologic responses to drug-paired cues cocaine-dependent men and women. METHODS: In a double-blind placebo-controlled cross-over study, cocaine-dependent men (n = 32), cocaine-dependent women (n = 30), control men (n = 32), and control women (n = 25) received either yohimbine or placebo prior to two cocaine cue exposure sessions. RESULTS: Yohimbine increased ratings of anxiety both before (p < 0.001) and after (p = 0.035) cues, and the post-cue increase in anxiety was more pronounced in women (p = 0.001). Yohimbine also significantly increased craving, compared with placebo (p < 0.05), following the cue presentation, and this effect was greater in women than men (gender by treatment interaction; p = 0.006). Yohimbine also increased salivary cortisol (p < 0.001) and dehydroepiandrosterone (p = 0.003) levels, regardless of diagnostic group. Women had a significantly greater heart rate response following yohimbine as compared with men (p < 0.001). CONCLUSIONS: Stress may increase the salience of cocaine cues for cocaine-dependent women as compared with men. This suggests gender differences in vulnerability to craving and relapse under stressful conditions.
