BACKGROUND: Although treatment-resistant and nontreatment-resistant depressed patients show structural brain anomalies relative to healthy controls, the difference in regional volumetry between these two groups remains undocumented. METHODS: A whole-brain voxel-based morphometry (VBM) analysis of regional volumes was performed in 125 participants' magnetic resonance images obtained on a 1.5 Tesla scanner; 41 had treatment-resistant depression (TRD), 40 nontreatment-resistant depression (non-TRD), and 44 were healthy controls...

The neurotrophic hypothesis of depression is supported by consistent findings of lower serum BDNF levels in depressed patients. Increasing evidence shows different clinical characteristics of patients with psychotic major depression versus nonpsychotic major depression. However, the possible association between BDNF and psychotic symptoms in depression has not been investigated. We recruited 90 treatment-resistant depression (TRD) patients and 90 gender- and age-matched healthy control subjects and examined serum BDNF in both groups...

BACKGROUND: Deep brain stimulation (DBS) for refractory psychiatric disorders shows promising effects on symptom-reduction, however, little is known regarding the effects of DBS on social outcome. METHODS: A PubMed search based on original studies of DBS for psychiatric disorders [treatment resistant depression (TRD), Gilles de la Tourette's syndrome (GTS), and obsessive compulsive disorder (OCD)] was conducted. Data on social outcome following surgery were extracted and analyzed...

BACKGROUND: Electroconvulsive Therapy (ECT) and Deep Brain Stimulation (DBS) are effective treatments for patients with treatment-resistant depression (TRD). However, a common side effect of ECT is autobiographical memory loss (e.g., personal experiences), whereas the impact of DBS on autobiographical memories has never been established. OBJECTIVE: Comparing autobiographical memories following DBS and ECT. METHODS: In two hospitals in The Netherlands, we interviewed 25 TRD patients treated with DBS of the ventral anterior limb of the internal capsule (vALIC), 14 TRD patients treated with ECT and 22 healthy controls (HC) with the Autobiographical Memory Inventory - Short Form (AMI-SF) in a prospective, longitudinal study between March 2010 and August 2016...

BACKGROUND: There is an urgent need to develop safe and effective treatments for patients with treatment-resistant depression (TRD). Several neurosurgical procedures have been developed to treat the dysfunctional brain circuits implicated in major depression. OBJECTIVES: This review describes the most common ablative procedures used to treat major depressive disorder: anterior cingulotomy, subcaudate tractotomy, limbic leucotomy, and anterior capsulotomy. The efficacy and safety of each are discussed and compared with other current and emerging modalities, including deep brain stimulation (DBS) and MR-guided focused ultrasound (MRgFUS)...

BACKGROUND: Recent studies demonstrating a rapid, robust improvement in treatment resistant depression (TRD) following a single sub-anesthetic infusion of ketamine have generated much excitement. However, these studies are limited in their generalizability to the broader TRD population due to their subject exclusion criteria which typically limit psychiatric comorbidity, concurrent medication, and level of suicide risk. This paper describes the safety and efficacy of sub-anesthetic ketamine infusions in a naturalistic TRD patient sample participating in a real-world TRD treatment program within a major university health system...

BACKGROUND: Changes in hippocampal gray matter volumes are proposed to be involved in pathogenesis, course, and treatment response of major depressive disorder. Converging evidence suggests that reduced neurogenesis may occur in treatment-resistant depression (TRD). Vagus nerve stimulation (VNS) is a well-defined, long-term brain stimulation treatment for TRD. However, its in vivo positive effect on hippocampal modulation as mechanism of action has never been investigated before in clinical studies...

Transmission ratio distortion (TRD) is a phenomenon where parental transmission of disease allele to the child does not follow the Mendelian inheritance ratio. TRD occurs in a sex-of-parent-specific or non-sex-of-parent-specific manner. An offset computed from the transmission probability of the minor allele in control-trios can be added to the loglinear model to adjust for TRD. Adjusting the model removes the inflation in the genotype relative risk (RR) estimate and Type 1 error introduced by non-sex-of-parent-specific TRD...

Previous studies reported that enhanced recovery pathway (ERP) is safe in elderly who did not require a specifically tailored protocol. In previous studies, elderly have been considered as a homogeneous cohort and the cut-off value to identify them was different. The aim of the present study is to assess the compliance to ERP and its impact on postoperative outcome in three subgroups of elderly patients with increasing ages. Prospectively collected data entered in an electronic Italian registry specifically designed for ERP were reviewed...

There are numerous antidepressants for the treatment of major depressive disorder (MDD) on the market. However, inadequate treatment response, therapeutic lag between drug administration and the onset of clinical improvement, and safety/tolerability issues with the use of contemporary antidepressants have accelerated the search for newer antidepressants with novel mechanisms of action. Areas covered: The authors review novel antidepressants with rapid efficacy for diverse MDD symptoms and have fewer adverse effects (AEs)...

REVIEW
Flavia R Carreno, Alan Frazer
Major depressive disorder (MDD) is prevalent. Although standards antidepressants are more effective than placebo, up to 35% of patients do not respond to 4 or more conventional treatments and are considered to have treatment-resistant depression (TRD). Considerable effort has been devoted to trying to find effective treatments for TRD. This review focuses on vagus nerve stimulation (VNS), approved for TRD in 2005 by the Food and Drugs Administration. Stimulation is carried by bipolar electrodes on the left cervical vagus nerve, which are attached to an implanted stimulator generator...

It has been over 50 years since a review has focused exclusively on the monoamine oxidase (MAO) inhibitor tranylcypromine (TCP). A new review has therefore been conducted for TCP in two parts which are written to be read preferably in close conjunction: part I - pharmacodynamics, pharmacokinetics, drug interactions, toxicology; and part II - clinical studies with meta-analysis of controlled studies in depression, practice of TCP treatment, place in therapy. The irreversible and nonselective MAO-A/B inhibitor TCP has been confirmed as an efficacious and safe antidepressant drug...

The αβ T cells are important components of the adaptive immune system and can recognize a vast array of peptides presented by MHC molecules. The ability of these T cells to recognize the complex depends on the diversity of the αβ TR, which is generated by a recombination of specific Variable, Diversity and Joining genes for the β chain, and Variable and Joining genes for the α chain. In this study, we analysed the genomic structure and the gene content of the TRB locus in Camelus dromedarius, which is a species belonging to the Tylopoda suborder...

Major depressive disorder (MDD) affects 3 to 17 % of adults. 15 to 30 % of patients with MDD suffer from treatment resistant depression (TRD). No international consensus defines TRD. The most common definition is " MDD that is not enough improved after two successive and different classes of antidepressant treatments in appropriate dose and duration ". The appropriate dose corresponds to maximal dose accepted by scientific reports and clinical recommendations, while the appropriate duration is around 6 weeks...

Linkage maps are widely used to investigate structure, function, and evolution of genomes. In speciation research, maps facilitate the study of the genetic architecture of reproductive isolation by allowing identification of genomic regions underlying reduced fitness of hybrids. Here we present a linkage map for European newts of the Lissotriton vulgaris species complex, constructed using two families of F2 L. montandoni × L. vulgaris hybrids. The map consists of 1146 protein-coding genes on 12 linkage groups, equal to the haploid chromosome number, with a total length of 1484 cM (1...

BACKGROUND: The present study was conducted to examine the hypothesis based on our previous studies, that the multiple diagnoses of comorbid anxiety disorders (ADs) and higher interpersonal sensitivity predict treatment-resistant depression (TRD). METHODS: The participants were 199 consecutive outpatients with major depressive disorder (MDD), who were comprehensively diagnosed using the Mini International Neuropsychiatric Interview (MINI). TRD was defined as the failure to achieve remission with two or more adequate antidepressant trials...
