Qualitative Analysis of Initial Palliative Care Consultations in Amyotrophic Lateral Sclerosis.

Background: Palliative care (PC) benefits patients with amyotrophic lateral sclerosis (ALS), however the needs of patients and caregivers and the optimal timing of PC discussions remains unclear. This study reports the analysis of PC consult notes from a larger feasibility trial. The specific aims of this analysis were to i) identify the PC needs of patients with ALS via qualitative analysis and ii) identify characteristics of patients and caregivers that could predict specific PC needs.

Palliative care at any stage of amyotrophic lateral sclerosis: a prospective feasibility study.

Introduction: Many patients with amyotrophic lateral sclerosis (ALS) receive palliative care (PC) very late or not at all. The impact of PC on patients with ALS and caregivers has not been quantified. Study goals included (1) measuring the impact of early PC on quality of life and mood of patients/caregivers and (2) describing patient/caregiver satisfaction with PC.

A review of potential neuropathological changes associated with ketamine.

Introduction: Ketamine is an established intervention for treatment-resistant depression (TRD). However, long-term adverse effects with repeated doses remain insufficiently characterized. Although several animal models have shown N-methyl-D-aspartate glutamate receptor antagonists to produce various neuropathological reactions, attention surrounding the risk of brain lesions has been minimal.

Hallucinogen persisting perceptual disorder: a scoping review covering frequency, risk factors, prevention, and treatment.

Introduction: Hallucinogen persisting perception disorder (HPPD) affects a subset of persons who use hallucinogens and is defined as the repeated experience of hallucinations and other perceptual disturbances as a result of prior intoxications. As select hallucinogens are under development for the treatment of selectmental disorders, there is a need to better characterize this disorder.

Areas Covered: A scoping review of the literature on HPPD was completed from inception to July 2021.

The effect of ketamine on anhedonia: improvements in dimensions of anticipatory, consummatory, and motivation-related reward deficits.

Anhedonia is a common, persistent, and disabling condition. However, available therapeutics primarily focus on the reduction of depressive and negative symptoms rather than amelioration of deficits in positive affect. As such, extant drug treatments remain largely ineffective in treating symptoms of anhedonia.

Examining the association between inflammation and motivational anhedonia in neuropsychiatric disorders: A systematic review.

Background: Inflammation, motivational anhedonia, and neuropsychiatric disorders are associated with significant functional impairment and are a major public health concern. The objective of this systematic review is to examine the relationship between inflammatory activity and motivational anhedonia in neuropsychiatric disorders.

Methods: Preclinical and clinical studies were qualitatively synthesized and summarized.

Association Between Mood Disorders and Risk of COVID-19 Infection, Hospitalization, and Death: A Systematic Review and Meta-analysis.

Importance: Preexisting noncommunicable diseases (eg, diabetes) increase the risk of COVID-19 infection, hospitalization, and death. Mood disorders are associated with impaired immune function and social determinants that increase the risk of COVID-19. Determining whether preexisting mood disorders represent a risk of COVID-19 would inform public health priorities.
