Original Research
Exposure Therapy, d-Cycloserine, and Functional Magnetic Resonance Imaging in Patients With Snake Phobia: A Randomized Pilot Study
Andrea M. Nave, David F. Tolin, and Michael C. Stevens
[Abstract] [Full Text] [Audio Summary]
Clinical Points
  • d-Cycloserine may accelerate the effects of exposure-based therapy for anxiety disorders.
  • One week after treatment, phobic patients who received exposure plus d-cycloserine exhibited a qualitatively different neural response to feared stimuli compared to patients who received exposure plus placebo.
  • d-Cycloserine augmentation of exposure therapy may enhance ventromedial prefrontal brain activity during and after exposures to phobic stimuli.

 

CYP2D6 Genotype Information to Guide Pimozide Treatment in Adult and Pediatric Patients: Basis for the US Food and Drug Administration’s New Dosing Recommendations
Hobart L. Rogers, Atul Bhattaram, Issam Zineh, Jogarao Gobburu, Mitchell Mathis, Thomas P. Laughren, and Michael Pacanowski
[Abstract] [Full Text] [Audio Summary]
Clinical Points
  • Cytochrome P450 2D6 (CYP2D6) poor metabolizers are at an increased risk for QT prolongation at standard doses of pimozide because of higher drug concentrations.
  • People who are CYP2D6 poor metabolizers should not receive more than 4 mg of pimozide daily if adults or 0.05 mg/kg daily (up to 4 mg daily) if children.
  • Clinicians can refer to the US Food and Drug Administration pimozide label for new guidance on dosing, titration, and CYP2D6 status testing recommendations.

 

Leptin, Abdominal Obesity, and Onset of Depression in Older Men and Women
Yuri Milaneschi, Eleanor M. Simonsick, Nicole Vogelzangs, Elsa S. Strotmeyer, Kristine Yaffe, Tamara B. Harris, Magdalena I. Tolea, Luigi Ferrucci, and Brenda W. J. H. Penninx, for the Health, Aging, and Body Composition Study
[Abstract] [Full Text] [Audio Summary]

Clinical Points
  • Obesity, in particular abdominal adiposity, is a risk factor for depression.
  • Leptin impaired central action (resistance) may represent a biological mechanism relating abdominal adiposity with depression onset in obese persons.
  • In obese depressed patients, the development of therapeutic interventions on leptin downstream pathways should target leptin central resistance rather than leptin itself.

 

Compensatory Cognitive Training for Psychosis: Effects in a Randomized Controlled Trial
Elizabeth W. Twamley, Lea Vella, Cynthia Z. Burton, Robert K. Heaton, and Dilip V. Jeste
[Abstract] [Full Text] [Supplementary Material] [Audio Summary]
Clinical Points
  • Compensatory cognitive training is a brief, manualized, low-tech intervention aimed at improving cognitive impairment and everyday functioning abilities in people with schizophrenia.
  • Our results showed that compensatory cognitive training led to improvements in attention, memory, functional capacity, negative symptom severity, and patient-rated quality of life.

 

Depressive Symptoms and Suicidal Thoughts Among Former Users of Finasteride With Persistent Sexual Side Effects
Michael S. Irwig
[Abstract] [Full Text] [Audio Summary]
Clinical Points
  • A subset of young men who take finasteride develop persistent sexual side effects accompanied by severe depressive symptoms and suicidal thoughts.
  • Prescribers and potential users of finasteride should be aware of the potential CNS side effects of this medication.

 

Maintenance Treatment With Long-Acting Injectable Risperidone in First-Episode Schizophrenia: A Randomized Effectiveness Study
Peter J. Weiden, Nina R. Schooler, Jeremy C. Weedon, Abdel Elmouchtari, and Ayako Sunakawa-McMillan
[Abstract] [Full Text]
Clinical Points
  • Most recently diagnosed, first-episode schizophrenia patients stop their antipsychotic medication within the first year of outpatient treatment.
  • Early initiation of long-acting antipsychotic therapy seems to delay but not prevent the onset of nonadherence in this patient population.
  • Nonadherence to oral therapy was usually not recognized in “real time” by the treating clinician. Given the likelihood of unrecognized nonadherence in first-episode patients, long-acting therapy offers an “information advantage” regarding efficacy and safety of the prescribed antipsychotic.

 

A 9-Week Randomized Trial Comparing a Chronotherapeutic Intervention (Wake and Light Therapy) to Exercise in Major Depressive Disorder Patients Treated With Duloxetine
Klaus Martiny, Else Refsgaard, Vibeke Lund, Marianne Lunde, Lene Sørensen, Britta Thougaard, Lone Lindberg, and Per Bech
[Abstract] [Full Text] [Supplementary Material] [Audio Summary]
Clinical Points
  • Combining wake therapy, light therapy, and sleep time stabilization with duloxetine treatment induced a very rapid and sustained increase in antidepressant response in patients with treatment resistance; this method offers an alternative to polypharmacy treatment.
  • Exercise in combination with duloxetine also induced a clinically meaningful antidepressant response, but less than the wake therapy, light therapy, and sleep time stabilization combined with duloxetine.
  • We found that the individually tailored exercise program was easy to implement and that patients were highly compliant and had very few side effects. We believe that the weekly assessment and guidance by a physiotherapist was very important in obtaining this high level of compliance.
  • Wake therapy was well tolerated, with a high level of compliance. Patients experienced only a moderate degree of sleepiness during the wake nights. Light therapy was also well tolerated, with a high degree of compliance. The sleep diary was found to be a helpful tool in stabilizing the sleep-wake cycle.

Panic Attacks as a Dimension of Psychopathology: Evidence for Associations With Onset and Course of Mental Disorders and Level of Functioning
Neeltje M. Batelaan, Didi Rhebergen, Ron de Graaf, Jan Spijker, Aartjan T. F. Beekman, and Brenda W. J. H. Penninx
[Abstract] [Full Text] [Audio Summary]
For Clinical Use
  • Panic attacks occur in a wide range of psychiatric disorders; that is, their occurrence is not limited to panic disorders or anxiety disorders.
  • Clinicians should be aware of the risk of onset of psychiatric disorders when patients present with panic attacks.
  • In patients with panic (panic disorders, panic attacks, past panic attacks), both mental functioning and physical functioning are more impaired than in those without panic.
Focus on Alzheimer’s Disease and Related Disorders
A Meta-Analytic Review of Polyunsaturated Fatty Acid Compositions in Dementia [Review Article]
Pao-Yen Lin, Chih-Chiang Chiu, Shih-Yi Huang, and Kuan-Pin Su
[Abstract] [Full Text] [Audio Summary]
Clinical Points
  • Studies have shown an association between peripheral blood levels of polyunsaturated fatty acids (PUFAs) and dementia and predementia syndrome.
  • Intervention with n-3 PUFAs might be beneficial for patients with dementia or predementia syndrome, but the outcomes are not consistent.
  • The results of this meta-analysis suggest that patients with dementia and predementia syndrome have lower levels of n-3 PUFAs, supporting an important role of n-3 PUFAs in cognitive disorders.

 

Efficacy of Nonpharmacologic Interventions for Agitation in Advanced Dementia: A Randomized, Placebo-Controlled Trial
Jiska Cohen-Mansfield, Khin Thein, Marcia S. Marx, Maha Dakheel-Ali, and Laurence Freedman
[Abstract] [Full Text] [Audio Summary]
Clinical Points
  • The study is the first large randomized, placebo-controlled clinical trial to show the impact on agitation of individualized nonpharmacologic interventions based on the unmet need model.
  • The effect size of the intervention was larger than in a previous study, probably due to (1) a rigorous methodology of ascertaining the optimal nonpharmacologic intervention, (2) greater experience in discerning and delivering the interventions, and (3) the accumulation of a wide variety of materials that could be matched to individual backgrounds and needs.
  • Nonpharmacologic interventions not only decreased agitation but also increased pleasure and interest, suggesting that these interventions contribute to improved quality of life for persons with dementia.

Practical Psychopharmacology
Breast Cancer and Antidepressant Use
Chittaranjan Andrade
[Abstract] [Full Text] [Audio Summary]
Clinical Points
  • Tamoxifen, an antiestrogen drug, is used for many indications related to breast cancer. Antidepressants are also often used in breast cancer patients, for states such as depression, anxiety, and hot flashes associated with chemical menopause.
  • Tamoxifen is a prodrug. Some antidepressants (eg, paroxetine, fluoxetine, bupropion, duloxetine) inhibit CYP2D6, the enzyme that converts tamoxifen into endoxifen, its most important active metabolite. This could compromise tamoxifen’s efficacy.
  • Clinicians should avoid CYP2D6 inhibitors in patients receiving tamoxifen in favor of drugs with low or no CYP2D6 inhibitor activity (eg, mirtazapine, escitalopram, fluvoxamine, reboxetine, citalopram, sertraline, venlafaxine, desvenlafaxine).

Wilfred R. Pigeon, Martin Pinquart, and Kenneth Conner
[Abstract] [Full Text]
Clinical Points
  • Sleep disturbances in general, and insomnia and nightmares specifically, are significantly associated with suicidal ideation, suicide attempt, and suicide.
  • Identification and management of sleep disturbance is a potentially useful strategy to alter the clinical course of individuals vulnerable to suicide.
