Hyperpolarization-activated cyclic nucleotide-gated (HCN) channels are expressed ubiquitously throughout the brain, where they function to regulate the excitability of neurons. The subcellular distribution of these channels in pyramidal neurons of hippocampal area CA1 is regulated by tetratricopeptide repeat-containing Rab8b interacting protein (TRIP8b), an auxiliary subunit. Genetic knockout of HCN pore forming subunits or TRIP8b, both lead to an increase in antidepressant-like behavior, suggesting that limiting the function of HCN channels may be useful as a treatment for Major Depressive Disorder (MDD)...

Use of stimulants to treat Attention-deficit/hyperactivity disorder (ADHD) has increased over the past two decades and varies substantially between countries. The objective of this multinational population-based study was to examine utilization of ADHD drugs (stimulants and atomoxetine) including co-medication with other psychothropic drugs in the entire child population in the five Nordic countries. We included longitudinal data on dispensed ADHD drugs from five Nordic prescription registers during 2008-2012; which in 2012 comprised 48,296 individuals among 5...

Magnesium is one of the most important elements in the human body and is involved in a number of biochemical processes crucial for the proper functioning of the cardiovascular, alimentary, endocrine, and osteoarticular systems. It also plays a vital modulatory role in brain biochemistry, influencing several neurotransmission pathways associated with the development of depression. Personality changes, including apathy, depression, agitation, confusion, anxiety, and delirium are observed when there is a deficiency of this element...

A higher magnesium intake may reduce the risk of depression. We analyzed this association in the SUN Mediterranean cohort with an expanded sample size (n = 15,836) and a long follow-up (median = 10.2 y). We followed 9,289 women (age = 34.8, SD = 10.4) and 6,547 men (age = 42.8, SD = 13.1) initially free of any history of depression for a new-onset of medically diagnosed depression (maximum follow-up = 15.9 y). All participants in this cohort were university educated. We systematically reviewed previous studies relating magnesium to depression...

OBJECTIVE: Cytokines have been reported to have key roles in major depressive disorder (MDD). However, much less is known about cytokines in MDD and antidepressant treatment due to the diversity of cytokines and the heterogeneity of depression. We investigated the levels of cytokines in patients with MDD compared with healthy subjects and their associations with antidepressant response. METHODS: We investigated the changes of several cytokines (eotaxin, sCD40L, IL-8, MCP-1alpha, TNF-alpha, INF-gamma and MIP-1alpha) by Luminex assay in 66 patients with MDD and 22 healthy controls...

Depression is a devastating disorder which has a high impact on the wellbeing of overall society. As such, need for innovative therapeutic agents are always there. Most of the researchers focused on N-methyl-d-aspartate receptor to explore the antidepressant like activity of new therapeutic agents. Dextromethorphan is a cough suppressant agent with potential antidepressant activity reported in mouse force swimming test. Considering N-methyl-d-aspartate as a forefront in exploring antidepressant agents, here we focused to unpin the antidepressant mechanism of dextromethorphan targeting N-methyl-d-aspartate receptor induced nitric oxide-cyclic guanosine monophosphate signaling...

Add-on ketamine anesthesia in electroconvulsive therapy (ECT) has been studied in depressive patients in several clinical trials with inconclusive findings. Two most recent meta-analyses reported insignificant findings with regards to the treatment effect of add-on ketamine anesthesia in ECT in depressive patients. The aim of this study is to update the current evidence and investigate the role of add-on ketamine anesthesia in ECT in depressive patients via a systematic review and meta-analysis. We performed a thorough literature search of the PubMed and ScienceDirect databases, and extracted all relevant clinical variables to compare the antidepressive outcomes between add-on ketamine anesthesia and other anesthetics in ECT...

BACKGROUND: Dementia, with Alzheimer's disease (AD) being the most common form, is a major hip fracture risk factor, but currently it is not known whether the same factors predict hip fracture among persons with and without dementia/AD. We compared the predictors of hip fracture and mortality after hip fracture in persons with and without AD. METHODS: An exposure-matched cohort of all community-dwellers of Finland who received a new clinically verified AD diagnosis in 2005-2011 and had no history of previous hip fracture (N = 67,072) and an age, sex, and region-matched cohort of persons without AD (N = 67,072)...

Prevalence of tricyclic antidepressants (TCAs) has not been explored in pilots. The National Transportation Safety Board (NTSB) aviation accident and the Federal Aviation Administration's Civil Aerospace Medical Institute (CAMI) toxicology and medical certification databases were searched for pilots fatally injured in aviation accidents. During 1990-2012, CAMI received bio-samples of pilots from 7037 aviation accidents. Of these, 2644 cases were positive for drugs. TCAs were present in 31. TCA blood concentrations ranged from therapeutic to toxic levels...

BACKGROUND: Hypothesised associations between in utero exposure to selective serotonin reuptake inhibitors (SSRIs) and congenital anomalies, particularly congenital heart defects (CHD), remain controversial. We investigated the putative teratogenicity of SSRI prescription in the 91 days either side of first day of last menstrual period (LMP). METHODS AND FINDINGS: Three population-based EUROCAT congenital anomaly registries- Norway (2004-2010), Wales (2000-2010) and Funen, Denmark (2000-2010)-were linked to the electronic healthcare databases holding prospectively collected prescription information for all pregnancies in the timeframes available...

This review presents the results of studies investigating the effects of transcranial magnetic stimulation (TKMS) on motor and non-motor symptoms of Parkinson's disease (PD). It has been found that TKMS reduces the severity of both motor and non-motor disorders without causing serious side-effects. Magnetic field therapy can be combined with pharmacological and non-drug therapies, including the use of dopaminergic therapy, antidepressants and anti-dementia drugs, as well as stereotactic operations. It is necessary to continue the study of the influence of TKMS on the severity of PD symptoms using different electromagnetic characteristics...

Electroacupuncture improves depressive behavior faster and with fewer adverse effects than antidepressant medication. However, the antidepressant mechanism of electroacupuncture remains poorly understood. Here, we established a rat model of chronic unpredicted mild stress, and then treated these rats with electroacupuncture at Yintang (EX-HN3) and Baihui (DU20) with sparse waves at 2 Hz and 0.6 mA for 30 minutes, once a day. We found increased horizontal and vertical activity, and decreased immobility time, at 2 and 4 weeks after treatment...

OBJECTIVE: Research has consistently shown that incarcerated women experience mental illness at disproportionate rates and heavily use psychiatric medication. This study examined factors related to incarcerated women's experiences and beliefs about psychotropic medications. METHODS: The researchers conducted a survey with 274 women incarcerated at a medium-security correctional institution in a Mid-Atlantic state. A 35-item questionnaire was created that solicited data on, among other things, experiences with and perceptions of psychotropic medication use and locus of control...

REVIEW
Eberhard Schlicker, Thomas Feuerstein
Presynaptic receptors are sites at which transmitters, locally formed mediators or hormones inhibit or facilitate the release of a given transmitter from its axon terminals. The interest in the identification of presynaptic receptors has faded in recent years and it may therefore be justified to give an overview of their occurrence in the autonomic and central nervous system; this review will focus on presynaptic receptors in human tissues. Autoreceptors are presynaptic receptors at which a given transmitter restrains its further release, though in some instances may also increase its release...

OBJECTIVE: Mitochondrial dysfunction and energy metabolism impairment are key components in the pathophysiology of bipolar disorder (BD) and may involve a shift from aerobic to anaerobic metabolism. Measurement of brain lactate in vivo using proton magnetic resonance spectroscopy (H-MRS) represents an important tool to evaluate mitochondrial and metabolic dysfunction during mood episodes, as well as to monitor treatment response. To date, very few studies have quantified brain lactate in BD...

Because of increased attention to the issue of trustworthiness of clinical practice guidelines, it may be that both transparency and management of industry associations of guideline development groups (GDGs) have improved. The purpose of the present study was to assess a) the disclosure requirements of GDGs in a cross-section of guidelines for major depression; and, b) the extent and type of conflicts of panel members. Treatment guidelines for major depression were identified and searched for conflict of interest policies and disclosure statements...
