Cumulative evidence shows a linkage between gut microbiota pattern and depression through the brain-gut microbiome axis. The aim of this systematic review was to identify the alterations of the gut microbiota patterns in people with depression compared to healthy controls. A comprehensive literature search of human studies, published between January 2000 and June 2019, was… Continue reading Altered Composition of Gut #Microbiota in #Depression: A Systematic Review

Pilot randomized controlled trial of a #hypnosis intervention for women with #bladder pain syndrome
To evaluate the feasibility and acceptability of a randomized controlled trial of a hypnosis intervention for the treatment of bladder pain syndrome/interstitial cystitis (BPS/IC) in women. MethodsWe conducted a parallel arm, non-blinded, pilot randomized controlled trial of standardized hypnosis sessions including a hypnosis web tool versus usual care in adult women with BPS/IC. Pilot study… Continue reading Pilot randomized controlled trial of a #hypnosis intervention for women with #bladder pain syndrome
Reinforcement learning links spontaneous cortical #dopamine impulses to reward
Extrasynaptic levels of dopamine in mouse cortex exhibit spontaneous impulses•Impulses are broadly distributed in amplitude and time, with a rate of about 0.01/s•Feedback was used to train mice to volitionally control their spontaneous impulses•Mice learned to reliably modulate dopamine impulses in order to receive a reward SummaryIn their pioneering study on dopamine release, Romo and… Continue reading Reinforcement learning links spontaneous cortical #dopamine impulses to reward
#Psilocybin induces rapid and persistent growth of dendritic spines in frontal cortex in vivo
Psilocybin ameliorates stress-related behavioral deficit in mice•Psilocybin increases spine density and spine size in frontal cortical pyramidal cells•Psilocybin-evoked structural remodeling is persistent for at least 1 month•The dendritic rewiring is accompanied by elevated excitatory neurotransmission SummaryPsilocybin is a serotonergic psychedelic with untapped therapeutic potential. There are hints that the use of psychedelics can produce neural… Continue reading #Psilocybin induces rapid and persistent growth of dendritic spines in frontal cortex in vivo
The effect of #depression status change on daily #cigarette smoking amount according to sex: an eleven-year follow up study of the Korea Welfare Panel Study
In the past decade, the Korean smoking rate has only decreased by 3%, despite several smoking control policies. There is a need for such policies to take smokers’ psychological characteristics into account. Depression is a well-known contributor to failed smoking cessation. This study aimed to examine the effect of smokers’ depression status changes on their… Continue reading The effect of #depression status change on daily #cigarette smoking amount according to sex: an eleven-year follow up study of the Korea Welfare Panel Study
#Social Health and #Cardiovascular Disease Risk Factors: A cross-sectional study in a healthy older adult population
Poor social health is a risk factor for cardiovascular disease (CVD), however an in-depth exploration of the link through CVD risk factors is lacking. AimTo examine the relationship between social health (social isolation, social support, loneliness) and CVD risk factors among healthy older women and men. MethodsData were from 11,498 healthy community-dwelling Australians aged ≥70… Continue reading #Social Health and #Cardiovascular Disease Risk Factors: A cross-sectional study in a healthy older adult population
The temporal representation of #experience in subjective #mood
Humans refer to their mood state regularly in day-to-day as well as clinical interactions. Theoretical accounts suggest that when reporting on our mood we integrate over the history of our experiences; yet, the temporal structure of this integration remains unexamined. Here, we use a computational approach to quantitatively answer this question and show that early… Continue reading The temporal representation of #experience in subjective #mood
A phase 2 trial of inhaled #nitrous oxide for treatment-resistant major #depression
Laughing gas improves depressionAbout one-third of individuals suffering from depression are at risk for treatment resistance. Whereas inhaled 50% nitrous oxide has early antidepressant effects on individuals with treatment-resistant major depression (TRMD), adverse effects can occur at this concentration. In this phase 2 clinical trial, Nagele et al. studied the effects of a single 1-hour… Continue reading A phase 2 trial of inhaled #nitrous oxide for treatment-resistant major #depression
