Unveiling the Mechanisms of a Remission in Major Depressive Disorder (MDD)-like Syndrome: The Role of Hippocampal Palmitoyltransferase Expression and Stress Susceptibility by Careen A. Schroeter, Anna Gorlova, Michael Sicker, Aleksei Umriukhin, Alisa Burova, Boris Shulgin, Sergey Morozov, Joao P. Costa-Nunes, Tatyana Strekalova

“…However, recent studies suggested a role for the downregulation of palmitoyl acetyltransferase (DHHC) 21 gene expression in the development of Major Depressive Disorder (MDD)-like syndrome. Here, we sought to investigate how susceptibility (sucrose preference below 65%) or resilience (sucrose preference > 65%) to stress-induced anhedonia affects DHHC gene expression in the hippocampus of C57BL/6J mice during the phase of spontaneous recovery from anhedonia. …”

Relationship between pharmacotherapy for major depressive disorder and healthcare utilisation in British Columbia, Canada: a retrospective population-based cohort by Sonya Cressman, Louisa Edwards, Kimberlyn McGrail, Stirling Bryan, Alison Hoens, Rohit Vijh, Sandra Peterson, Zeina Waheed, Mary Bunka, Nick Pang, Shahzad Ghanbarian, Gavin Wong, Linda Riches, Jehannine Austin

“…Objectives To describe the population that meets the criteria for major depressive disorder (MDD) in British Columbia (BC), compare patterns of healthcare utilisation between those with MDD who are and are not prescribed pharmacotherapy, and assess these relationships in models that control for potential confounding variables.Design We used a population cross-sectional study design among a cohort of individuals living with MDD and examined the relationship between pharmacotherapy and healthcare utilisation between 2019 and 2020 using linked billing and administrative data.Setting This study identified individuals with MDD using a validated case definition of International Classification of Diseases (ICD) codes in BC, Canada.Participants The final study cohort included 549 029 adult participants who met the MDD case definition.Explanatory variable Explanatory variable was the use of prescription antidepressant medication during the study period, based on BC PharmaNet data.Covariates Covariates include sociodemographic characteristics (age, sex, urban/rural residence, neighbourhood income quintile and comorbidities).Primary outcome measure Primary outcome measure was healthcare utilisation (outpatient physician visits, emergency department (ED) visits and hospitalisations).Results We stratified our analysis based on whether study participants were classified as ‘recently incident’ or ‘actively prevalent’. …”

Brain-wide activation involved in 15 mA transcranial alternating current stimulation in patients with first-episode major depressive disorder by Jie Wang, Qing Xue, Wenfeng Zhao, Huang Wang, Haixia Leng, Mao Peng, Xiukun Jin, Liucen Tan, Keming Gao, Hongxing Wang, Baoquan Min

“…Background Although 15 mA transcranial alternating current stimulation (tACS) has a therapeutic effect on depression, the activations of brain structures in humans accounting for this tACS configuration remain largely unknown.Aims To investigate which intracranial brain structures are engaged in the tACS at 77.5 Hz and 15 mA, delivered via the forehead and the mastoid electrodes in the human brain.Methods Actual human head models were built using the magnetic resonance imagings of eight outpatient volunteers with drug-naïve, first-episode major depressive disorder and then used to perform the electric field distributions with SimNIBS software.Results The electric field distributions of the sagittal, coronal and axial planes showed that the bilateral frontal lobes, bilateral temporal lobes, hippocampus, cingulate, hypothalamus, thalamus, amygdala, cerebellum and brainstem were visibly stimulated by the 15 mA tACS procedure.Conclusions Brain-wide activation, including the cortex, subcortical structures, cerebellum and brainstem, is involved in the 15 mA tACS intervention for first-episode major depressive disorder. …”
