Social Isolation, Loneliness and Generalized Anxiety: Implications and Associations during the COVID-19 Quarantine.

The COVID-19 pandemic has resulted in a predominantly global quarantine response that has been associated with social isolation, loneliness, and anxiety. The foregoing experiences have been amply documented to have profound impacts on health, morbidity, and mortality. This narrative review uses the extant neurobiological and theoretical literature to explore the association between social isolation, loneliness, and anxiety in the context of quarantine during the COVID-19 pandemic.

Trace amine-associated receptor 1 (TAAR1): Potential application in mood disorders: A systematic review.

There is a need for innovation with respect to therapeutics in psychiatry. Available evidence indicates that the trace amine-associated receptor 1 (TAAR1) agonist SEP-363856 is promising, as it improves measures of cognitive and reward function in schizophrenia. Hedonic and cognitive impairments are transdiagnostic and constitute major burdens in mood disorders.

Management of cognitive impairment in bipolar disorder: a systematic review of randomized controlled trials.

Cognitive impairment is common in bipolar disorder and is emerging as a therapeutic target to enhance quality of life and function. A systematic search was conducted on PubMed, PsycInfo, Cochrane, clinicaltrials.gov, and Embase databases for blinded or open-label randomized controlled trials evaluating the pro-cognitive effects of pharmacological, neurostimulation, or psychological interventions for bipolar disorder.

Associations Among Screen Time, Sleep Duration and Depressive Symptoms Among Chinese Adolescents.

Objectives: Relatively few studies have explored the inter-relationship between screen time (ST), sleep duration and depressive symptoms. The study herein sought to determine (1) the relationships between ST, sleep duration and depressive symptoms among Chinese adolescents; (2) whether sleep duration mediates the relationships between ST and depressive symptoms.

Methods: 1 grade students (n=1,976) from ten high schools in Guangzhou, China were invited through cluster sampling between January and April 2019.

The influence of prescriber and patient gender on the prescription of benzodiazepines: results from the Florida Medicaid Dataset.

Background: Benzodiazepine (BZD) prescription rates have increased over the past decade in the United States. Available literature indicates that sociodemographic factors may influence diagnostic patterns and/or prescription behaviour. Herein, the aim of this study is to determine whether the gender of the prescriber and/or patient influences BZD prescription.

The effect of intravenous, intranasal, and oral ketamine in mood disorders: A meta-analysis.

Background: Ketamine is established as a rapid and effective treatment in adults with treatment-resistant depression (TRD). The availability of different formulations and routes of delivery invites the need for evaluating relative effect sizes.

Methods: Effect size with respect to depression symptom reduction for each formulation and route of delivery was compared at discrete time-points (i.

Association of history of adverse childhood experiences with irritable bowel syndrome (IBS) in individuals with mood disorders.

The objective of the current study was to assess the association between adverse childhood experiences (ACEs) and irritable bowel syndrome (IBS) in mood disorder patients. Self-report data from the International Mood Disorders Collaborative Project were cross-sectionally analyzed to compare rates of IBS in participants with confirmed diagnoses of major depressive disorder (MDD; n = 279) or bipolar disorder (BD; n = 219). Data was sub-grouped and compared based on history of ACEs.

Keeping up with the clinical advances: depression.

Major depressive disorder (MDD) is a prevalent and heterogeneous disorder. Although there are many treatment options for MDD, patients with treatment-resistant depression (TRD) remain prevalent, wherein delayed time to response results in inferior chances of achieving remission. Recently, therapeutics have been developed that depart from the traditional monoamine hypothesis of depression and focus instead on the glutamatergic, GABAergic, opioidergic, and inflammatory systems.
