Healthcare workers face greater risks for mental health conditions and chronic stress due to the demanding nature of their roles. The COVID-19 pandemic exacerbated these challenges and increased vulnerabilities to long-term mental health conditions. The present study adapts an existing resilience-based educational workshop program to address the time constraints and unique needs of the healthcare workforce in a post-COVID-19 world.

Article Synopsis
  • The article discusses the creation and validation of a new self-report resilience scale called the Mount Sinai Resilience Scale (MSRS), which focuses on thoughts and behaviors that enhance resilience rather than just personality traits.
  • An online study involving 1,864 U.S. adults was conducted to develop and confirm the scale's effectiveness, revealing a seven-factor structure through exploratory and confirmatory analyses.
  • The revised 24-item scale showed strong correlations with other recognized measures of resilience, supporting its validity and suggesting it could be a useful tool in the mental health field.

Objective: Posttraumatic stress disorder (PTSD) is a chronic and disabling disorder, for which available pharmacotherapies have limited efficacy. The authors' previous proof-of-concept randomized controlled trial of single-dose intravenous ketamine infusion in individuals with PTSD showed significant and rapid PTSD symptom reduction 24 hours postinfusion. The present study is the first randomized controlled trial to test the efficacy and safety of repeated intravenous ketamine infusions for the treatment of chronic PTSD.

Background: Though there is a growing body of research establishing a broad negative psychological impact of COVID-19 among healthcare workers (HCWs), there are comparably fewer studies evaluating symptom presentation and clinical diagnoses among treatment-seeking HCWs. The present report seeks to fill this gap in the literature by establishing the prevalence of anxiety, depression, post-traumatic stress, alcohol misuse, and well-being among treatment-seeking HCWs.

Method: Data were collected from 421 treatment-seeking HCWs in an outpatient hospital-based mental health setting.

This study investigated third year medical students' psychological well-being during clinical rotations at Mount Sinai hospitals in New York City during the COVID-19 pandemic. All students (n = 147) starting rotations (psychiatry, surgery, obstetrics-gynecology, neurology, pediatrics, and medicine) could participate in quarterly, online, anonymous surveys comprised of validated screeners for: psychological symptoms, risk, coping, and protective factors, demographics, COVID-19 worries, and stressful clerkship-related events. Associations between variables were examined with Chi-squared, Fisher's exact, t-, Wilcoxon Rank Sum, one-way ANOVA, and McNemar tests.

Background: Stress exposure is a key risk factor for the development of major depressive disorder and posttraumatic stress disorder. Enhancing stress resilience in at-risk populations could potentially protect against stress-induced disorders. The administration of ketamine one week prior to an acute stressor prevents the development of stress-induced depressive-like behavior in rodents.

Poor psychological health is associated with Takotsubo cardiomyopathy, cardiac syndrome X, coronary microcirculatory dysfunction, peripheral artery disease, or spontaneous coronary artery dissection. Data regarding pessimism, cardiovascular disease (CVD) events and mortality and all-cause mortality remained inconclusive. This systematic review and meta-analysis aim to provide an overview of the association between pessimism, CVD outcomes and mortality.

Some research suggests that distress, secondary to isolation and fear following COVID-19 infection, can negatively affect the long-term more than the COVID-19 infection itself. This narrative review aims to provide a global view on the neuropsychiatric consequences of COVID-19 that can be ascribed to several factors, ranging from the direct effect of infection, to the body's responses against the infection, or to the psychological sequelae of social isolation, unemployment, and fear for one's health and livelihood. Current findings show that the more severe the respiratory infection, the more likely are central nervous system (CNS) complications regarding the infection itself.

Depression is disabling and highly prevalent. Intravenous (IV) ketamine displays rapid-onset antidepressant properties, but little is known regarding which patients are most likely to benefit, limiting personalized prescriptions. We identified randomized controlled trials of IV ketamine that recruited individuals with a relevant psychiatric diagnosis (e.

Stress exposure is one of the greatest risk factors for psychiatric illnesses, including major depressive disorder (MDD) and posttraumatic stress disorder (PTSD). Enhancing stress resilience could potentially protect against the development of stress-induced psychiatric disorders, yet no resilience-enhancing pharmaceuticals have been developed to date. This review serves to consider the existing evidence for a potential pro-resilience effect of ketamine in rodents as well as the preliminary evidence of ketamine as a prophylactic treatment for postpartum depression (PPD) in humans.

Objective: Frontline healthcare workers (FHCWs) responding to the COVID-19 pandemic develop posttraumatic stress disorder (PTSD), major depressive disorder (MDD) and generalized anxiety disorder (GAD) symptoms. Such symptoms are associated with burnout, occupational and relational difficulties. In the current study, we examined the prospective association between acute transdiagnostic COVID-19-related PTSD, MDD, and GAD symptoms at pandemic outset, and burnout and functional difficulties several months later in FHCWs in New York City.

Despite experiencing a significant trauma, only a subset of World Trade Center (WTC) rescue and recovery workers developed posttraumatic stress disorder (PTSD). Identification of biomarkers is critical to the development of targeted interventions for treating disaster responders and potentially preventing the development of PTSD in this population. Analysis of gene expression from these individuals can help in identifying biomarkers of PTSD.

Article Synopsis
  • - Ketamine shows quick and lasting antidepressant effects in treatment-resistant depression (TRD) patients, but how it works is still unclear.
  • - The study compared blood samples from TRD patients and healthy controls to analyze gene expression before and after ketamine treatment, finding an interferon signaling pathway activation in TRD patients at baseline.
  • - Responders to ketamine exhibited specific gene upregulation, but the study didn't find changes indicating an anti-inflammatory effect, suggesting more research is needed to understand the immune system's role in ketamine's effects.
