ABSTRACT

As the histories of psychiatry, neurology, and neuroimaging interweave through time, psychiatry has only recently started to recognize the need to embrace neuroimaging like its sibling specialty. While imaging in psychiatric research is well accepted, there is current clinical utility as well. Standards for psychiatry residency and board certification in the USA and abroad have carved out a place for neuroimaging, but the implementation is variable and sparse in the USA. The few publications that describe neuroimaging teaching to psychiatrists have barriers to widespread adoption, and no comprehensive curricular solution has been developed. In this context, we describe some of the barriers and propose solutions to shape the future of neuroimaging education for psychiatrists.

ABSTRACT

Q fever is frequently associated with the development of antiphospholipid antibodies though rarely causes thromboses. A 44-year-old man presented with diarrhea and fevers and was found to have a splenic infarct. Infectious work-up revealed acute Q fever as well as high anticardiolipin antibody titers. He was treated with doxycycline and hydroxychloroquine and suffered no further thromboembolic complications. The optimal management of thromboembolic complications is uncertain given the rarity of documented cases. However, the presence of these antibodies has been associated with increased risk of complications. Further investigation into the management of patients with Q fever associated hypercoagulability is needed.

ABSTRACT

Opioid use disorder (OUD) and overdose deaths are a public health crisis. One contributing factor is stigma towards people who use opioids. We developed and conducted a public-facing, half-day educational event designed to challenge misperceptions about OUD from a contemporary neuroscience perspective. Participants engaged with three different resources on the neurobiology of addiction, and, at the end of the event, they rated its effectiveness. We also collected and compared pre- and post-event composite OUD stigma scales. Participants rated our approach and the overall event as highly effective. Additionally, OUD stigma scores were lower immediately following the event, and this decrease was primarily driven by decreased internalized stigma. Here, we demonstrate an effective proof-of-concept that an accessible, public-facing, neuroscience education event may reduce OUD stigma in the community.

ABSTRACT

BACKGROUND: Neurocysticercosis is a parasitic infection of the central nervous system. Cysts located in the ventricles, intraventricular neurocysticercosis (IVNCC), can cause symptoms of increased intracranial pressure and, if untreated, can be fatal. Neuroendoscopic removal of IVNCC is recommended as the first-line treatment. OBSERVATIONS: The authors present the case of a healthy 30-year-old male originally from Mexico who presented with headaches and vomiting. He was found to have a cyst in the third ventricle on imaging, consistent with IVNCC. The authors successfully performed neuroendoscopic surgery with removal of the cyst en bloc. LESSONS: A multidisciplinary team of neurosurgery and infectious disease specialists is recommended for successful management of patients with IVNCC. These patients typically require neuroendoscopic surgical removal for definitive treatment. In this case, the authors show surgery resulted in an effective cure without the need for antiparasitic medication and excellent long-term outcomes.

ABSTRACT

The absolute photoabsorption cross sections of norbornadiene (NBD) and quadricyclane (QC), two isomers with chemical formula C7H8 that are attracting much interest for solar energy storage applications, have been measured from threshold up to 10.8 eV using the Fourier transform spectrometer at the SOLEIL synchrotron radiation facility. The absorption spectrum of NBD exhibits some sharp structure associated with transitions into Rydberg states, superimposed on several broad bands attributable to valence excitations. Sharp structure, although less pronounced, also appears in the absorption spectrum of QC. Assignments have been proposed for some of the absorption bands using calculated vertical transition energies and oscillator strengths for the electronically excited states of NBD and QC. Natural transition orbitals indicate that some of the electronically excited states in NBD have a mixed Rydberg/valence character, whereas the first ten excited singlet states in QC are all predominantly Rydberg in the vertical region. In NBD, a comparison between the vibrational structure observed in the experimental 11B1-11A1 (3sa1 ← 5b1) band and that predicted by Franck-Condon and Herzberg-Teller modeling has necessitated a revision of the band origin and of the vibrational assignments proposed previously. Similar comparisons have encouraged a revision of the adiabatic first ionization energy of NBD. Simulations of the vibrational structure due to excitation from the 5b2 orbital in QC into 3p and 3d Rydberg states have allowed tentative assignments to be proposed for the complex structure observed in the absorption bands between ∼5.4 and 7.0 eV.

ABSTRACT

The light-induced ultrafast switching between molecular isomers norbornadiene and quadricyclane can reversibly store and release a substantial amount of chemical energy. Prior work observed signatures of ultrafast molecular dynamics in both isomers upon ultraviolet excitation but could not follow the electronic relaxation all the way back to the ground state experimentally. Here we study the electronic relaxation of quadricyclane after exciting in the ultraviolet (201 nanometres) using time-resolved gas-phase extreme ultraviolet photoelectron spectroscopy combined with non-adiabatic molecular dynamics simulations. We identify two competing pathways by which electronically excited quadricyclane molecules relax to the electronic ground state. The fast pathway (<100 femtoseconds) is distinguished by effective coupling to valence electronic states, while the slow pathway involves initial motions across Rydberg states and takes several hundred femtoseconds. Both pathways facilitate interconversion between the two isomers, albeit on different timescales, and we predict that the branching ratio of norbornadiene/quadricyclane products immediately after returning to the electronic ground state is approximately 3:2.

ABSTRACT

Reports of tecovirimat-resistant mpox have emerged after widespread use of antiviral therapy during the 2022 mpox outbreak. Optimal management of patients with persistent infection with or without suspected resistance is yet to be established. We report a successfully treated case of severe mpox in California, USA, that had suspected tecovirimat resistance.

ABSTRACT

Research on emotional intelligence has provided robust support for its importance for job performance and leadership success. More recently, research is turning to understand the impact emotional intelligence has on personal success and physical and mental well-being. Thus, the current study examines emotional intelligence from a Work-Home Resources perspective, exploring what components within the Emotional Quotient model of emotional intelligence can serve as a buffer for work-family conflict. Additionally, this study examines if the contextual resource of EI executive coaching can serve as a method of modifying the personal resource of emotional intelligence. As leaders and practitioners are increasingly focusing attention on employee development of emotional intelligence competencies, our study examines EI executive coaching as a method to increase emotional intelligence, not only for performance improvement, but also for personal well-being. Using a diverse sample of employees and leaders measured at two time points, the current study found that emotional intelligence is negatively related to work-family conflict. Further, an increase in specific dimensions of emotional intelligence through EI executive coaching is related to a decrease in work-family conflict. Implications for theory and practice are discussed.

ABSTRACT

Alzheimer's Disease (AD) represents the most common type of dementia and is becoming a steadily increasing challenge for health systems globally. Inflammation is developing as the main focus of research into Alzheimer's disease and has been demonstrated to be a major driver of the pathologies associated with AD. This evidence introduces an interesting research question, whether chronic inflammation due to pathologies such as inflammatory bowel disease (IBD) and rheumatoid arthritis (RA) could lead to a higher risk of developing dementia. In both IBD and RA, increased levels of the inflammatory biomarker C-reactive protein (CRP) can be highlighted, the latter being directly implicated in neuroinflammation and AD. In this meta-analysis both the association between chronic inflammatory diseases and elevated levels of CRP during midlife were investigated to examine if they correlated with an augmented risk of dementia. Moreover, the association between increased CRP and modifications in the permeability of the Blood Brain Barrier (BBB) in the presence of CRP is explored. The results displayed that the odds ratio for IBD and dementia was 1.91 [1.15-3.15], for RA it was 1.90 [1.09-3.32] following sensitivity analysis and for CRP it was 1.62 [1.22-2.15]. These results demonstrate a higher risk of dementia in patients presenting chronic inflammation and that exists an independent association with high CRP in midlife. This paper builds on published research that suggest a critical role for CRP both in stroke and AD and provides an analysis on currently published research on multiple diseases (IBD and RA) in which CRP is raised as well as chronically elevated. CRP and the associated risk of dementia and further research indicated that the monomeric form of CRP can infiltrate the BBB/be released from damaged micro-vessels to access the brain. This meta-analysis provides first-time evidence that chronic elevation of CRP in autoimmune diseases is directly associated with an increased risk of later development of Alzheimer's disease. Therefore, greater priority should be provided to the effective control of inflammation in patients with chronic inflammatory or autoimmune conditions and further long-term assessment of circulating CRP might inform of an individual's relative risk of developing dementia.

ABSTRACT

BACKGROUND: The emerging 2022 human mpox virus outbreak has presented with unique disease manifestations challenging prior case definitions. CASE REPORT: We present a case of a 42-year-old transgender woman with human immunodeficiency virus controlled on antiretroviral therapy, presenting with sore throat, who, after three emergency department visits, was found to have acute tonsillitis complicated by airway obstruction secondary to mpox. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Sore throat is a common presentation to the emergency department. mpox should be placed on the list of differential diagnoses when evaluating patients who present with pharyngitis to avoid complications or a missed diagnosis.

ABSTRACT

Mpox (formally monkeypox) is an Orthopoxvirus associated with both zoonotic and person-to-person spread. Human mpox classically presents with rash and systemic symptoms. Although sporadic outbreaks of mpox have occurred worldwide, the 2022 outbreak is the first of pandemic significance. Thousands of geographically dispersed cases were reported beginning in May 2022. The clinical presentations and outcomes of mpox infection have varied greatly based on viral clade. Further guidance is needed for clinicians to diagnose and treat this emerging infection. We present five clinical vignettes of confirmed cases diagnosed in June and July 2022 in northern California to demonstrate the range of mpox disease, including myocarditis, pharyngitis, epididymitis, and proctitis. We note a significant overlap with HIV infection and a high rate of concurrent sexually transmitted infection. Given the heterogenous presentations of mpox disease, clinicians should maintain a high degree of suspicion in patients with oropharyngeal or genital lesions, proctitis, or new rash.

ABSTRACT

Neurologic clinical care requires that clinicians gather and synthesize complex information, including a thorough, precise history and a detailed physical examination that maximizes the patient's cooperation. Yet, for patients who do not speak the dominant language in the country or region where they live, effective communication with their clinician may not always occur. In this article, we discuss the impact of language on neurologic care, focusing on access to care and on the diagnosis and treatment of two common and potentially life-threatening conditions: stroke and epilepsy. We then review implications for clinical neurologic care as well as medical education and present evidence-based recommendations for improving neurologic health equity for linguistically diverse populations. Strategies should integrate professional medical interpreters (for oral communication) and translators (for written materials) into the neurologic team, account for families and caregivers in a culturally humble manner, and teach learners to apply clinical neurologic skills in both language-concordant and discordant situations.
