Cognitive Deficits Following Coronary Artery Bypass Grafting: Prevalence, Prognosis, and Therapeutic Strategies
Authors: Raja Pushpa V. , Blumenthal James A. , Doraiswamy P. Murali 
Published: August 2016

AbstractThere is increasing recognition that coronory artery bypass grafting (CABG) may be a risk factor for subtle cognitive decline although the presence and pattern of such decline has varied across studies. Cognitive deficits may present as short-term memory loss, executive dysfunction and psychomotor slowing. Although they are usually are not severe enough to meet criteria for mild cognitive impairment or vascular dementia, they lower quality of life and add to hospitalization and out-of-hospital costs. Proposed mechanisms include surgical-related trauma, genetic susceptibility (eg, apolipoprotein E4 allele), microembolization, other vascular or ischemic changes, and temperature during surgery. Depression and anxiety levels predict subjective perception of these deficits more than objective cognitive performance. Both nonpharmacologic (eg, emboli reduction, temperature, or glucose management) and pharmacologic (eg, dexanabinol, glypromate, nootropics) strategies to prevent post-CABG cognitive deficits are under investigation. Given the large numbers of subjects who may already have CABG associated cognitive deficits, clinical trials of agents being tested for Alzheimer's disease (eg, donepezil, rivastigmine, memantine, neramexane, ginkgo) may also be informative. The results of multicenter long-term outcome studies (with matched control groups) as well as ongoing treatment trials will more conclusively address some of these issues. These data emphasize the need for clinicians to monitor cognitive function before and after coronary bypass surgery, and to educate patients.
Perimenopausal Mental Disorders: Epidemiology and Phenomenology
Authors: Rasgon Natalie , Shelton Stephanie , Halbreich Uriel 
Published: August 2016

AbstractPerimenopause, the interval of irregular menstrual activity which directly precedes menopause, is characterized by widely fluctuating hormone levels amidst a large-scale decline in circulating estrogen. This phase in a woman's life is typically accompanied by physical discomforts including vasomotor symptoms, such as headaches, insomnia, and hot flushes, as well as genital atrophy. Not surprisingly, studies suggest a significant increase in mood lability for women during this time. While some evidence points toward an exacerbation of bipolar mood symptoms and an increase in schizophrenic psychosis during perimenopause, the majority of research conducted on perimenopausal mental disorders has focused on unipolar depression. Studies vary widely in methodology, definitions of menopausal status, and degrees of depression among subjects; however, the majority of findings indicate an increased susceptibility to depression during the perimenopausal transition. This greater susceptibility may be due to neuroendocrine effects of declining estrogen levels, the subjective experience of somatic symptoms resulting from this hormonal decline, and/or the more frequent occurrence of “exit” or “loss” events for women during this stage of life. At this time, more research is needed to address questions of prevalence, risk, and etiology for depression and other major mental disorders as related to the physiological and psychosocial changes associated with perimenopause.
Suicide: Risk, Impact, and Prevention
Authors: Goodwin Frederick K. , Ghaemi S. Nassir , Hollander Eric 
Published: August 2016

The power of the life force is striking—in even among the most abominable conditions, like concentration camps, suicide remains relatively uncommon. Yet some human beings appear to harbor a powerful destructive force, which can under certain conditions manifest itself in violence, homicide, or suicide. Suicide has been with us since the beginning of history; it has often been romanticized, or viewed as an understandable escape from an intolerable situation. Philosophers and writers from William James to Albert Camus to Goethe have tended to view suicide as a window into the human condition, perhaps extreme but nevertheless a reflection of our shared humanity. However, highly reliable research has shown that suicide is, by and large, not a window into the human condition, but rather a manifestation of a disturbance—an abnormality of the human condition—a mental disorder.Physicians know that the primary goal of medical treatment (after first doing no harm) is to prevent death. Death is the ultimate enemy in medical illness. In psychiatric illness, this enemy usually appears in the guise of suicide; the illness uses the hands of patients to wreak its havoc. To reduce mortality in psychiatric conditions, then, means to reduce suicide. It is indeed striking how little this matter has been analyzed. Little data are available on mortality with medications that are researched and approved for psychiatric illness. This would not be acceptable for medical illnesses outside of psychiatry today; it should not be the case in psychiatric illnesses either.

Published: August 2016

AbstractCan psychological factors, such as depression, affect human immunodeficiency virus progession? HIV infection is viewed as a chronic illness in which those infected often confront a number of emotional challenges and physical health and disease-related issues. Over the past 20 years, there has been increasing evidence that depression and other mood-related disturbances are commonly observed among HIV-positive individuals. There is also mounting data showing that depressive symptoms might further impact upon specific elements of immune system functioning and influence quality of life and health status. This paper will highlight studies examining the prevalence of depression during HIV infection and review some of the evidence examining the impact of depressive symptoms on immune function and HIV disease progression.

Published: August 2016

ABSTRACTBackground: Exposure-based therapy for anxiety disorders is believed to operate on the basis of fear extinction. Studies have shown acute administration of D-cycloserine (DCS) enhances fear extinction in animals and facilitates exposure therapy in humans, but the neural mechanisms are not completely understood. To date, no study has examined neural effects of acute DCS in anxiety-disordered populations.Methods: Two hours prior to functional magnetic resonance imaging scanning, 23 spider-phobic and 23 non-phobic participants were randomized to receive DCS 100 mg or placebo. During scanning, participants viewed spider, butterfly, and Gaussian-blurred baseline images in a block-design paradigm. Diagnostic and treatment groups were compared regarding differential activations to spider versus butterfly stimuli.Results: In the phobic group, DCS enhanced prefrontal (PFC), dorsal anterior cingulate (ACC), and insula activations. For controls, DCS enhanced ventral ACC and caudate activations. There was a positive correlation between lateral PFC and amygdala activation for the placebo-phobic group. Reported distress during symptom provocation was correlated with amygdala activation in the placebo-phobic group and orbitofrontal cortex activation in the DCS-phobic group.Conclusions: Results suggest that during initial phobic symptom provocation DCS enhances activation in regions involved in cognitive control and interoceptive integration, including the PFC, ACC, and insular cortices for phobic participants.
Selective Phosphodiesterase Type-5 Inhibitor Treatment of Serotonergic Reuptake Inhibitor Antidepressant-Associated Sexual Dysfunction: A Review of Diagnosis, Treatment, and Relevance
Authors: Nurnberg H. George , Hensley Paula L. 
Published: August 2016

AbstractSexual dysfunction related to antidepressants, particularly serotonin reuptake inhibitors is a major cause of premature treatment discontinuation. This places patients at increased risk for recurrence, relapse, chronicity, and mortality (eg, suicide). The clinical assessment requires a comprehensive evaluation of sexual function, including libido, arousal, orgasm, and resolution prior to affective disorder, disturbances associated with the emergence of depression, and changes or dysfunctions associated with antidepressant treatment. Other factors to be included for evaluating sexual dysfunction include inquiry for concurrent medical conditions, somatic treatments, lifestyle risk factors, and response to antidepressants. Current treatment approaches to antidepressant-associated sexual dysfunction have relied on open-label reports, literature reviews, and clinical wisdom. Without double-blind, placebo-controlled studies to support them, too much non-evidence-based treatment may be offered to patients. Advances into nonadrenergic-noncholinergic novel signal transduction, specifically phosphodiesterase type-5 inhibitors, offer new opportunities for developing evidence-based treatments for this side effect and improving depression disease management outcomes.
What Is the Rationale for New Treatment Strategies in Alzheimer's Disease?
Authors: Rogawski Michael A. 
Published: August 2016

AbstractAlzheimer's disease (AD) is characterized by the abnormal extracellular accumulation of amyloid β-peptide (Aβ) into neuritic plaques and the intraneuronal aggregation of the microtubule-associated protein tau to form neurofibrillary tangles. These molecular events are implicated in the selective damage to neural systems critical for the brain functions that are impaired in AD. Impairment of cholinergic neurotransmission may be an important factor underlying the defects in cognition and memory that characterize AD. Cholinesterase (ChE) inhibitors, such as donepezil, rivastigmine, and galantamine, cause symptomatic improvement by inhibiting the breakdown of the neurotransmitter acetylcholine to increase its synaptic availability and, in the case of galantamine, by also allosterically potentiating nicotinic cholinergic receptors. Other agents, including vitamin E, monoamine oxidase inhibitors, and statins, have shown some benefit in epidemiological studies and clinical trials although compelling evidence of their efficacy is lacking. Memantine, shown to cause cognitive and functional improvement, is not an ChE inhibitor and does not interact with marketed ChE inhibitors. While the mechanism of action of memantine in AD is not known, the principal pharmacologic actions at therapeutic dose are inhibition of ionotropic neurotransmitter receptors, specifically N-methyl-D-aspartate (NMDA), 5-HT3, and nicotinic receptors. Like other NMDA antagonists, memantine causes behavioral activation associated with enhanced cerebral glucose utilization. Studies have shown that memantine can reverse the decreased metabolic activity associated with AD, possibly accounting for its beneficial effects on cognition and global functioning. Memantine also has neuroprotective properties and can inhibit Aβ-induced neurodegeneration.
What Are the Challenges Faced by Psychiatrists in the Management of Alzheimer's Disease?
Authors: Mintzer Jacobo E. 
Published: August 2016

AbstractAlzheimer's disease (AD) is a debilitating condition affecting millions of elderly citizens. The quality of life for AD patients significantly deteriorates in the face of worsening cognitive deficits and disabling functional declines, both contributing to manifestations of difficult behaviors. Of the estimated 4 million individuals with AD, only 60% of probable AD cases are diagnosed, with little more than half of those receiving treatment. One of the possible reasons for this problem is the large role primary care physicians (PCPs) have in diagnosing and treating AD. The barriers that PCPs confront to adequately manage these patients will be discussed. Finally, the specific challenges that geriatric psychiatrists will face in addressing these issues in an environment where there is only a limited number of trained geriatric psychiatrists will be discussed, as well as the possible role that new technology could have in finding the solution to this difficult problem.
Obsessive-Compulsive Disorder and Its Potential Subtypes
Authors: Black Donald W. 
Published: August 2016

AbstractThis manuscript summarizes presentations by an international panel of experts, representing Brazil, Israel, Italy, Mexico, Portugal, Spain, and the United States, at a symposium on obsessive-compulsive disorder (OCD) and its possible subtypes. Presentations concerned both OCD proper, as well as putative obsessive-compulsive-spectrum disorders (autistic disorders, eating disorders, pathological gambling, and schizo-obsessive disorder). Projects discussed included a study assessing impulsive temperament in eating disorder patients, a study on serotonin receptor sensitivity in autism, a study of sleep EEG abnormalities in OCD, a study of dissociation in pathological gamblers, papers on aspects of schizo-obsessive patients, a study addressing biological alterations in OCD, data from a new family study on OCD, data from a molecular genetic study of OCD, a factor analytic study of Tourette disorder, a study hypothesizing the existence of an OCD continuum, and, finally, a paper on early- vs late-onset OCD. General discussion followed leading to a consensus that 1) OCD is likely heterogeneous with multiple subtypes; 2) division of patients by age-at-onset probably represents a robust and valid subtyping scheme; 3) the presence of schizophrenic features probably identifies a valid subtype; 4) the validation of subtypes in the future will be informed by both family-genetic studies, as well as studies of biological alterations in OCD; and 5) the study of obsessive-compulsive spectrum disorders adds to our understanding of the OCD phenomenon, and helps in our search to identify valid subtypes.
Treating the Mind and Body in Schizophrenia: Risks and Prevention
Authors: Meyer Jonathan M. 
Published: August 2016

AbstractPatients with schizophrenia have increased mortality due to higher rates of suicide. However, natural causes of death, such as cardiovascular disease, also contribute greatly to excess mortality. Significant sources of cardiovascular risk in this patient population include high smoking prevalence, inactive lifestyles, poor dietary habits, and the metabolic effects of atypical antipsychotics. These sources of risk interact with underrecognition of common medical conditions by mental health providers, limited access to primary care services, and undertreatment of health conditions in the general medical setting. For many patient with severe mental illness, the mental health setting represents the sole source of medical care, making the psychiatrist the de facto primary care provider for these individuals. With the recent focus on medical consequences of antipsychotic treatment, psychiatrist have an obligation to minimize these adverse effects by choosing antipsychotics with lower risk for metabolic side effects, and becoming familiar with the screening and management of common medical conditions.
Making Advances Where It Matters: Improving Outcomes in Mood and Anxiety Disorders
Authors: Golden Robert N. 
Published: August 2016

AbstractMood and anxiety disorders are among the most prevalent psychiatric illnesses and are associated with considerable morbidity and mortality. Selective serotonin reuptake inhibitors (SSRIs) are safe and effective treatments for major depression and anxiety disorders, and have become the most widely prescribed antidepressants worldwide. However, several issues limit SSRI treatment outcomes. Although SSRIs have a wider therapeutic margin and a milder side-effect profile compared to earlier antidepressants, even minor SSRI side effects can have a major impact on treatment outcomes by interfering with patient compliance. Nausea is one of the most common early SSRI side effects, and advances in SSRI delivery systems can diminish this. A controlled-release formulation of paroxetine targets the site of absorption for a more distal region of the small intestine, thereby avoiding the stimulation of upper gastrointestinal serotonin receptors that mediate nausea. The sustained-release characteristics also reduce the amplitude in blood level peaks and troughs, which may lead to diminished side effects and enhanced efficacy. Sexual side effects and weight gain are important sustained SSRI side effects, which affect compliance during continuation and maintenance phases of treatment. Several strategies address SSRI sexual side effects, including the use of adjunctive medication and/or manipulations in the scheduling of drug administration. Depression negatively impacts the management of many medical illnesses, including cardiovascular disease, cancer, and infectious diseases. The recognition and treatment of depression leads to improved outcomes in the management of breast cancer. Prophylactic SSRI treatment significantly reduces the incidence of interferon-associated depression and enhances completion rates in malignant melanoma.
Metabolic and Endocrine Disturbances in Psychiatric Disorders: A Multidisciplinary Approach to Appropriate Atypical Antipsychotic Utilization

Published: August 2016

AbstractPatients with psychiatric disorders have an increased rate of cardiovascular morbidity and mortality compared with the general population. Metabolic issues such as weight gain, dyslipidemia, diabetes mellitus, diabetic ketoacidosis, and pancreatitis have been reported with the use of antipsychotic agents. Although atypical antipsychotics have not been linked directly to the development of metabolic syndrome, these medications have been shown to increase risk factors that can lead to metabolic and endocrine disturbances. Therefore, clinicians should provide ongoing monitoring for patients who are being treated for psychiatric disorders with these agents. According to the 2004 Consensus Report on Antipsychotics, screening measures should include baseline and follow-up monitoring of personal/family histories, weight (body mass index), waist circumference, blood pressure, fasting plasma glucose, and fasting lipid profile.
Treatment of Bipolar Disorder During the Postpartum Period
Authors: Viguera Adele C. 
Published: August 2016

AbstractThe presentations and clinical courses of patients with bipolar disorder differ greatly by gender. In addition, medical therapy must be tailored differently for men and women because of emerging safety concerns unique to the female reproductive system. In November 2005, these topics were explored by a panel of experts in psychiatry, neurology, and reproductive health at a closed roundtable meeting in Dallas, Texas. This clinical information monograph summarizes the highlights of that meeting.Compared to men with bipolar disorder, women have more pervasive depressive symptoms and experience more major depressive episodes. They are also at higher risk for obesity and certain other medical and psychiatric comorbidities. Mood changes across the menstrual cycle are common, although the severity, timing, and type of changes are variable. Bipolar disorder is frequently associated with menstrual abnormalities and ovarian dysfunction, including polycystic ovarian syndrome. Although some cases of menstrual disturbance precede the treatment of bipolar disorder, it is possible that valproate and/or antipsychotic treatment may play a contributory role in young women.Pregnancy does not protect against mood episodes in untreated women. Maintenance of euthymia during pregnancy is critical because relapse during this period strongly predicts a difficult postpartum course. Suspending therapy in the first months of pregnancy may be an option for some women with mild-to-moderate illness, or those with a long history of euthymia during pre-pregnancy treatment. However, a mood stabilizer should be reintroduced either in the later stages of pregnancy or in the immediate postpartum period. Preliminary data suggest that fetal exposure to some mood stabilizers may raise the risk of major congenital malformations and neurodevelopmental delays. For women planning to become pregnant, clinicians may consider switching to other drugs before conception. The value and drawbacks of breastfeeding during treatment must be considered in partnership with the patient, with close monitoring of nursing infants thereafter. The risks and benefits of medical treatment for women with bipolar disorder should be carefully reconsidered at each stage of their reproductive lives, with a flexible approach that is responsive to the changing needs of patients and their families.
Recent Advances in the Understanding and Treatment of Anxiety Disorders
Authors: Stein Dan J. 
Published: August 2016

Anxiety disorders are the most prevalent of the psychiatric disorders, account for a significant proportion of mental illness costs, and include some of the most disabling medical disorders. Anxiety disorders, which currently include the obsessive-compulsive disorders, continue to be poorly diagnosed and undertreated across a broad range of countries. It is possible that the universal experience of anxiety as an adaptive emotion makes it more difficult for patients and clinicians to conceptualize symptoms in terms of psychopathology.Nonetheless, there have been significant advances in our understanding of anxiety and obsessive-compulsive disorders, and in our ability to manage these conditions successfully. Research on anxiety and obsessive-compulsive disorders exemplifies the goals of translational investigation; preclinical work has not only allowed an exploration of known clinical phenomena, but has also led directly to novel clinical interventions. Investigators around the globe are continuing to contribute to research on anxiety and obsessive-compulsive disorders.
Evidence-based Guidelines for Anxiety Disorders: Can They Improve Clinical Outcomes?
Authors: Baldwin David S. 
Published: August 2016

AbstractEvidence-based medicine (EBM) enables clinicians to justify decision making, enhances the quality of medical practice, identifies unanswered research questions, and ensures the efficient practice of medicine. Implementation of evidence-based mental health programs requires education, time, and improved effort by administration, regulatory, and clinical professionals. Essential to these efforts are consistent incentives for change, effective training materials, and clear clinical guidelines. Guidelines exist within the framework of EBM. Good guidelines are simple, specific, and user friendly, focus on key clinical decisions, are based on research evidence, and present evidence and recommendations in a concise and accessible format. Potential limitations of guidelines to improve clinical outcomes in anxiety disorders are the widespread distribution of anxiety symptoms in primary care, health inequalities across patient groups, persistent misconceptions regarding psychotropic drugs, and low confidence in using simple psychological treatments. Clinical guidelines generally specify therapeutic areas covered and not covered, but often there is no mention of cost or cost effectiveness of treatment. Guidelines can inform clinical decision making, but administrators of drug formularies may regard themselves as being primarily responsible for limiting costs and access to certain medications, even if these decisions are at odds with guideline recommendations.
