Rationale: There is increasing interest in establishing psychedelic research programs at academic medical centers. However, psychedelics are intensely psychoactive, carry considerable sociopolitical baggage, and most are Schedule I drugs, creating significant potential impediments to implementation. There is little formal guidance for investigators on navigating the complex on-the-ground obstacles associated with establishing psychedelic research programs.

Article Synopsis
  • The ELEKT-D trial explored whether intravenous ketamine is as effective as ECT for patients with treatment-resistant depression (TRD), finding that ketamine is noninferior to ECT in this group.
  • This secondary analysis aimed to identify which clinical features might predict better outcomes with either ketamine or ECT in treating TRD.
  • The study involved 365 participants from five U.S. medical centers, comparing treatment responses based on various baseline factors, such as depression severity and cognitive function, using advanced statistical methods.

Data on medication interactions with psychedelics are limited. Here we present what may be the first published report of a hypertensive emergency following the combination of psilocybin mushrooms with a monoamine oxidase inhibitor (MAOI). A 42-year-old man with treatment-resistant major depressive disorder took 1 g of mushrooms, while prescribed tranylcypromine, extended-release dextroamphetamine-amphetamine, and other medications.

For more than 2 decades, intravenous ketamine has been demonstrated to have rapid antidepressant effects. However, access to this generic drug is limited due to insurers claiming it is "experimental" because ketamine does not have a Food and Drug Administration indication for depression. In contrast, intranasal esketamine, an enantiomer of ketamine, is approved by the Food and Drug Administration for depression and is still under patent.

Objective: This study aimed to investigate the frequency of long COVID diagnosis among patients infected with severe acute respiratory syndrome coronavirus 2 with preexisting psychiatric conditions versus those without preexisting psychiatric conditions.

Methods: The TriNetX Analytics platform, an aggregated electronic health record research network containing the deidentified electronic health record data of more than 90 million patients, was queried for patients who were diagnosed with COVID-19 infection based on International Classifications of Disease, Tenth Revision codes. Patients were stratified based on their preexisting psychiatric conditions, and new diagnoses of long COVID were recorded and reported as the primary outcome.

Article Synopsis
  • The study aimed to improve the clinical diagnosis of Alexander disease (AxD) by using neurite orientation dispersion and density imaging (NODDI) in a rat model, hoping to uncover new quantitative biomarkers for the disease.
  • Researchers performed advanced multi-shell diffusion-weighted imaging (DWI) on both AxD-affected and healthy rats, analyzing brain microstructure differences across various brain regions with due consideration to genotype and biological sex factors.
  • Results revealed significant differences in brain microstructure between AxD and normal rats, with notable variations linked to biological sex, indicating that sex may influence the disease’s neuropathogenesis.

Objectives: Little contemporary research has explored phencyclidine (PCP) use in people with alcohol use disorder. Therefore, we sought to determine the prevalence of PCP positivity on urine toxicology screening among patients admitted for alcohol withdrawal, identify correlates of PCP positivity, and investigate PCP positivity's relationship to length of stay (LOS) and risk of facility readmission.

Methods: This was a retrospective study of patients admitted to a dual-diagnosis medically assisted withdrawal unit for alcohol withdrawal from 2014 to 2019.

Objective: To evaluate the relationship between race, economic status, and patient characteristics with benzodiazepine prescribing in an urban and suburban primary care context.

Method: This retrospective study used data from a previously described cohort of patients seen in a large Ohio healthcare system's primary care clinics from 2019 to 2020. Associations and interactions between race, economic status (using median income of patient ZIP code as a proxy), patient characteristics, and prescription of benzodiazepines were assessed using multivariable logistic regression.

Cultural awareness of anosmia and microsmia has recently increased due to their association with COVID-19, though treatment for these conditions is limited. A growing body of online media claims that individuals have noticed improvement in anosmia and microsmia following classic psychedelic use. We report what we believe to be the first three cases recorded in the academic literature of improvement in olfactory impairment after psychedelic use.

Background: Catatonia due to a general medical condition may result from a variety of causes, including substance intoxication and withdrawal. Stimulants are occasionally associated with catatonia, though there has been little investigation of methamphetamine's relationship to catatonia. Here we present 5 cases of catatonia associated with methamphetamine use and a systematic review of the associated literature from 1943 to 2020.

Introduction: Geroscience studies of low-dose rapamycin in laboratory species have identified numerous benefits, including reversing age-related cardiac dysfunction. Cardiovascular benefits have been observed in dogs with 10 weeks of treatment, raising questions about possible benefits and adverse effects of long-term use of low-dose rapamycin. The objectives of this study were to assess the impact of 6 months of low-dose rapamycin on echocardiographic indices of cardiac function in healthy dogs and to document the occurrence of adverse events.

Background: Patients with cerebral palsy, a group of movement disorders with motor, and possibly communication and behavioral features that mimic catatonic signs, may benefit from efforts to improve the detection and treatment of comorbid catatonia. Given that cerebral palsy frequently co-occurs with conditions associated with catatonia, such as autism spectrum disorder, epilepsy, intellectual disability, and mood and psychotic disorders, lifetime prevalence of catatonia in this population may be high.

Objective: This study aimed to systematically review the literature on catatonia and the related condition of neuroleptic malignant syndrome (NMS) in patients with cerebral palsy while presenting 2 additional cases of catatonia.

Objectives: A resurgence of research investigating the administration of psychedelic compounds alongside psychotherapy suggests that this treatment is a promising intervention for anxiety, depression, and existential distress in people with cancer. However, psychedelic treatment that induces a mind-altering experience potentially poses barriers to vulnerable cancer patients, and health-care practitioners may have concerns about referring their patients to trials investigating this approach. The aim of the current study was to investigate the perceptions of cancer health-care practitioners based in New Zealand and the USA related to psychedelic-assisted therapy.
