Natural volatile oils derived from herbal medicines: A promising therapy way for treating depressive disorder.

Depression is a common global mental disorder that seriously harms human physical and mental health. With the development of society, the increase of pressure and the role of various other factors make the incidence of depression increase year by year. However, there is a lack of drugs that have a fast onset, significant effects, and few side effects. Some volatile oils from traditional natural herbal medicines are usually used to relieve depression and calm emotions, such as Lavender essential oil and Acorus tatarinowii essential oil. It was reported that these volatile oils, are easy to enter the brain through the blood-brain barrier and have good antidepressant effects with little toxicity and side effects. In this review, we summarized the classification of depression, and listed the history of using volatile oils to fight depression in some countries. Importantly, we summarized the anti-depressant natural volatile oils and their monomers from herbal medicine, discussed the anti-depressive mechanisms of the volatile oils from natural medicine. The volatile oils of natural medicine and antidepressant drugs were compared and analyzed, and the application of volatile oils was explained from the clinical use and administration routes. This review would be helpful for the development of potential anti-depressant medicine and provide new alternative treatments for depressive disorders.

Indices of Change, Expectations, and Popularity of Biological Treatments for Major Depressive Disorder between 1988 and 2017: A Scientometric Analysis.

BACKGROUND: Major Depressive Disorder (MDD) is the most common psychiatric disorder with high prevalence and disease burden. Biological treatments of MDD over the last several decades include a wide range of antidepressants and neurostimulation therapies. While recent meta-analyses have explored the efficacy and tolerability of antidepressants, the changing trends of biological treatments have not been evaluated. Our study measured the indices of change, expectations, and popularity of biological treatments of MDD between 1988 and 2017. METHODS: We performed a scientometric analysis to identify all relevant publications related to biological treatments of MDD from 1988 to 2017. We searched the Web of Science websites for publications from 1 January 1988 to 31 December 2017. We included publications of fluoxetine, paroxetine, citalopram, sertraline, amitriptyline, fluvoxamine, escitalopram, venlafaxine, duloxetine, milnacipran, desvenlafaxine, levomilnacipran, clomipramine, nortriptyline, bupropion, trazodone, nefazodone, mirtazapine, agomelatine, vortioxetine, vilazodone, electroconvulsive therapy (ECT), repetitive transcranial magnetic stimulation (rTMS), vagus nerve stimulation (VNS), deep brain stimulation (DBS), and transcranial direct current stimulation (tDCS). We excluded grey literature, conference proceedings, books/book chapters, and publications with low quality as well as publications not related to medicine or human health. The primary outcomes assessed were indices of change, expectations, and popularity. RESULTS: Of 489,496 publications identified, we included 355,116 publications in this scientometric analysis. For the index of change, fluoxetine, sertraline and ECT demonstrated a positive index of change in 6 consecutive periods. Other neurostimulation therapies including rTMS, VNS, DBS and tDCS had shown a positive index of change since 1998. We calculated the index of change of popularity index (PI), which indicates that from 2013 to 2017, the number of publications on tricyclic antidepressants (TCAs) and monoamine oxidase inhibitors (MAOIs) were reduced by 85.0% and 81.3% respectively, as compared with the period 2008-2012. For the index of expectation, fluoxetine and ECT showed the highest index of expectations in six consecutive periods and remained the highest in 2013-2017. For popularity, the three antidepressants with highest PI were fluoxetine (4.01), paroxetine (2.09), and sertraline (1.66); the three antidepressants with lowest PI were desvenlafaxine (0.08), vilazodone (0.04) and levomilnacipran (0.03). Among neurostimulation therapies, ECT has the highest PI (2.55), and tDCS the lowest PI (0.14). The PI of SSRI remained the highest among all biological treatments of MDD in 2013-2017. In contrast, the PI of ECT was reduced by approximately 50% during the period 2008 to2012 than that in the period 2013 to 2017. CONCLUSIONS: This scientometric analysis represents comprehensive evidence on the popularity and change in prospects of biological treatments for MDD from 1988 to 2017. The popularity of SSRI peaked between 1998 and 2002, when their efficacy, tolerability and safety profile allowed them to replace the TCAs and MAOIs. While the newer neurostimulation therapies are gaining momentum, the popularity of ECT has sustained.

The effect of sildenafil on quality of life.

BACKGROUND: Antidepressant-induced sexual dysfunction affects approximately 50% of patients taking antidepressants. Previous research has explored sildenafil's effectiveness in treating various forms of erectile dysfunction, but there is no research supporting sildenafil's use for improving the quality of life for patients with sexual dysfunction linked to antidepressant use. The authors of this article aimed to assess the improvements in quality of life in patients taking sildenafil to treat antidepressant-induced sexual dysfunction. METHODS: One hundred and two out of 2,239 male and female patients in the follow-up phase of the Sequenced Treatment Alternatives to Relieve Depression antidepressant trials who complained of sexual dysfunction were given sildenafil, 50 to 100 mg, as needed. After 12 months, we measured patients' change in libido, sexual drive, family relationships, overall well-being, satisfaction with treatment, and overall contentment with items on the 17-item Hamilton Depression Rating Scale, Quality of Life Enjoyment and Satisfaction Questionnaire, 30-item Inventory of Depressive Symptoms, and 12-item Short Form Health Survey. RESULTS: There was a significant association between sildenafil use and improvement in libido and sexual drive by month 6. There was no significant improvement in the quality-of-life scores we examined, but treatment satisfaction and overall contentment increased over time. CONCLUSIONS: Despite no direct association with sildenafil use and quality-of-life scores, sildenafil may be a beneficial treatment for antidepressant-induced sexual dysfunction. A double-blind, placebo-controlled study of sildenafil in antidepressant-induced sexual dysfunction is needed to further explore its potential benefits.

[Treatment of insomnia]. / Therapie der Insomnie.

The prevalence of insomnia is high in the population of western industrial countries (up to 35 %). Sleep disturbance may consequently lead to an impairment of cognitive functions, mood disturbance and metabolic alterations. Therefore, the confirmation of insomnia and its diagnostic characterization is of great importance. Treatment of insomnia is based on its aetiology and intensity. For secondary insomnia treatment of the basic disorder is mandatory. Before the initiation of a symptomatic pharmacological treatment the application of non-pharmacological interventions should be considered. Efficacious pharmacological interventions are non-benzodiazepine hypnotics for a limited time span. If a longer treatment of insomnia is necessary, hypnotic antidepressants and hypnotic neuroleptics (without anti-cholinergic action) can be applied taking the specific side effects into account. Classical benzodiazepines and substances with anti-cholinergic properties should be avoided in particular in long-term treatment and in elderly subjects due to its side effect profile.

World Federation of Societies of Biological Psychiatry (WFSBP) Guidelines for Biological Treatment of Unipolar Depressive Disorders in Primary Care.

These practical guidelines for the biological treatment of unipolar depressive disorders in primary care settings were developed by an international Task Force of the World Federation of Societies of Biological Psychiatry (WFSBP). They embody the results of a systematic review of all available clinical and scientific evidence pertaining to the treatment of unipolar depressive disorders and offer practical recommendations for general practitioners encountering patients with these conditions. The guidelines cover disease definition, classification, epidemiology and course of unipolar depressive disorders, and the principles of management in the acute, continuation and maintenance phase. They deal primarily with biological treatment (including antidepressants, other psychopharmacological and hormonal medications, electroconvulsive therapy, light therapy).

New developments in antidepressant therapy.

Depression is an overwhelmingly common problem in the United States. It is not only life threatening, but also costly, both personally and financially. Following a brief overview of depression, this article presents a variety of treatment modalities. Advantages and dis-advantages of each intervention are explored along with suggestions for evaluating current and future advances in treatment options.

Opportunities to discover genes regulating depression and antidepressant response from rodent behavioral genetics.

Over the past several years, research has indicated that an individual's genetic makeup strongly influences not only their likelihood of developing depression, but also whether or not they will respond well to a particular antidepressant treatment. Identifying those genes regulating susceptibility to depression will increase our understanding of disease pathophysiology and direct the development of treatments that correct underlying neurobiological pathology related to stress-related psychiatric illnesses. Pharmacologically, the identification of genes regulating treatment response can lead to the design of novel pharmacological treatments and allow for more individualized, rational and successful drug treatments. Unfortunately, complex environmental and genetic mechanisms at play in depression and drug response make the discovery of susceptibility genes in humans quite difficult. Animal models may provide a more desirable system in which to discover susceptibility genes because environmental factors and tests can be regulated and more informative genetic methods can be used. Furthermore, a unique genetic opportunity exists with animal models of depression and antidepressant response because several rodent strains have been identified, or selectively bred, that display exaggerated depressive phenotypes on stress-related behavioral tests or divergent responses to antidepressant drugs. This paper reviews several of these rodent strains and illustrates the genetic strategies available to discover the long-sought susceptibility genes regulating these phenotypes.

Antidepressant medication use and non-Hodgkin's lymphoma risk: no association.

Animal and human studies have suggested that antidepressant medications may be associated with several cancers. The authors evaluated the association between antidepressant medication use and the risk of non-Hodgkin's lymphoma using a Canadian population-based case-control study, the National Enhanced Cancer Surveillance Study. Non-Hodgkin's lymphoma cases (n=638) diagnosed in 1995-1996 were identified using the Ontario Cancer Registry, and controls (n=1,930) were identified from the Ontario Ministry of Finance Property Assessment Database. Antidepressant medication use was ascertained using a self-administered questionnaire. Multivariate logistic regression was used to estimate odds ratios. "Ever" use of antidepressant medications was not associated with non-Hodgkin's lymphoma risk. The odds ratio for non-Hodgkin's lymphoma with 25 or more months of tricyclic antidepressant medication use was 1.6; however, this was nonsignificant. Duration or history of use or individual types of antidepressant medications were not associated with non-Hodgkin's lymphoma risk. These findings do not support an increased risk of non-Hodgkin's lymphoma with antidepressant medication use.

Use of antidepressant drugs in transplant recipients.

Depression is the most prevalent psychiatric disorder in transplant recipients and may lead to noncompliance and negative outcomes without psychosocial and pharmacologic interventions. The pharmacologic treatment of depression in this patient population is complicated by complex immunosuppressant drug regimens and multiple potential drug interactions that can adversely affect the newly transplanted organs. This review provides a brief overview of the currently available antidepressant medications and highlights the clinically important features each class of agents in transplant recipients. Newer agents selective serotonin reuptake inhibitors, venlafaxine, bupropion, nefazodone, and mirtazapine are discussed as well as tricyclic antidepressants and monoamine oxidase inhibitors. A brief discussion of St. John's wort and its impact on posttransplant drug therapy is also included.

Somatic treatment for depressive illnesses in children and adolescents.

Numerous somatic interventions have been studied as potential treatments of depressive disorders in children and adolescents. These include antidepressant medications, light therapy, electro-convulsive therapy, and alternative therapies. The available evidence suggests that several somatic interventions hold promise as potentially safe and effective treatments for depressed youths; however, there is still much to be learned about these interventions. This article reviews what is known and what needs to be learned about the somatic treatment of pediatric depression.

World Federation of Societies of Biological Psychiatry (WFSBP) Guidelines for Biological Treatment of Unipolar Depressive Disorders, Part 1: Acute and continuation treatment of major depressive disorder.

These practice guidelines for the biological treatment of unipolar depressive disorders were developed by an international Task Force of the World Federation of Societies of Biological Psychiatry (WFSBP). The goal for developing these guidelines was to systematically review all available evidence pertaining to the treatment of unipolar depressive disorders, and to produce a series of practice recommendations that are clinically and scientifically meaningful based on the available evidence. These guidelines are intended for use by all physicians seeing and treating patients with these conditions. The data used for developing these guidelines have been extracted primarily from various national treatment guidelines and panels for depressive disorders, as well as from meta-analyses and reviews on the efficacy of antidepressant medications and other biological treatment interventions identified by a search of the MEDLINE database and Cochrane Library. The identified literature was evaluated with respect to the strength of evidence for its efficacy and was then categorized into four levels of evidence (A-D). This first part of the guidelines covers disease definition, classification, epidemiology and course of unipolar depressive disorders, as well as the management of the acute and continuation-phase treatment. These guidelines are primarily concerned with the biological treatment (including antidepressants, other psychopharmacological and hormonal medications, electroconvulsive therapy, light therapy, adjunctive and novel therapeutic strategies) of young adults and also, albeit to a lesser extent, children, adolescents and older adults.

Clinical guidelines for the treatment of depressive disorders. IV. Medications and other biological treatments.

BACKGROUND: The Canadian Psychiatric Association and the Canadian Network for Mood and Anxiety Treatments partnered to produce clinical guidelines for psychiatrists for the treatment of depressive disorders. METHODS: A standard guidelines development process was followed. Relevant literature was identified using a computerized Medline search supplemented by review of bibliographies. Operational criteria were used to rate the quality of scientific evidence, and the line of treatment recommendations included consensus clinical opinion. This section, "Medications and Other Biological Treatments," is 1 of 7 articles that were drafted and reviewed by clinicians. Revised drafts underwent national and international expert peer review. RESULTS: Evidence-based recommendations are presented for 1) choosing an antidepressant, based on efficacy, tolerability, and safety; 2) the optimal use of antidepressants, including augmentation, combination, and switching strategies; 3) maintenance treatment; and 4) electroconvulsive therapy (ECT), light therapy, and additional somatic treatments. Evidence from metaanalyses is presented first, followed by conclusions from randomized controlled trials (RCTs) and, if appropriate, open-label data. CONCLUSIONS: There is significant evidence to support the role of selective serotonin reuptake inhibitors (SSRIs), novel agents, and classic agents in the treatment of major depressive disorder (MDD). There is also evidence to support the use of somatic treatments, including ECT and light therapy, for some patients with MDD. There is limited evidence for the use of specific medications to treat subtypes of MDD. There is emerging evidence to support augmentation and combination strategies for patients previously nonresponsive to medication.

Clinical and physiological consequences of rapid tryptophan depletion.

We review here the rapid tryptophan depletion (RTD) methodology and its controversial association with depressive relapse. RTD has been used over the past decade to deplete serotonin (5-hydroxy-tryptamine, or 5-HT) in humans and to probe the role of the central serotonin system in a variety of psychiatric conditions. Its current popularity was stimulated by reports that RTD reversed the antidepressant effects of selective serotonin reuptake inhibitors (SSRIs) and monoamine oxidase inhibitors (MAOIs) in remitted patients with a history of depression but not in patients treated with antidepressants which promote catecholaminergic rather than serotonergic neurotransmission (such as tricyclic antidepressants or buproprion). However, RTD has inconsistent effects in terms of full clinical relapse in depressed patients. Pooling the data from all published reports, patients who are either unmedicated and/or fully remitted are much less likely to experience relapse (7 of 61, or approximately 9%) than patients who are recently medicated and partially remitted (63 of 133, or approximately 47%; although, the numbers here may reflect patient overlap between reports). Recently remitted patients who have been treated with non-pharmacological therapies such as total sleep deprivation, electroconvulsive therapy, or bright light therapy also do not commonly show full clinical relapse with RTD. We briefly review RTD effects in other psychiatric disorders, many of which are treated with SSRIs. There is accumulating evidence to suggest that RTD affects central serotonergic neurotransmission. Nevertheless, many questions remain about the ability of RTD to reverse the beneficial effects of SSRIs or MAOIs, or to induce symptoms in unmedicated symptomatic or asymptomatic patients.

The circadian system and the therapeutics of the affective disorders.

Establishing that a circadian rhythm is abnormal tells us little about the cause, which can arise from changes in the patient's lifestyle, irregularities of the body clock or a malfunction in the process of entrainment of the clock. In a clinical context, such a range of possible explanations implies differences in the most appropriate mode of treatment. Against this background, the conventional view that the underlying abnormality in endogenous depression is due to a disorder of the body clock is challenged. The challenge is based on difficulties of interpretation of the clinical data and the results of studies on circadian rhythms in patients. It is suggested that the state of the circadian system in depression resembles its state in healthy individuals after time-zone transitions or in shift work maladaptation syndrome and that this disturbance should be seen as resulting from changes in the phasing of external zeitgebers rather than from an abnormality in the clock itself.
