Septic Cavernous Sinus Thrombosis: Clinical Characteristics, Management, and Outcomes.

BACKGROUND: Septic cavernous sinus thrombosis (CST) is a rare condition traditionally associated with high morbidity and mortality. More recent case series report more favorable outcomes, including full functional recovery. A comprehensive assessment of the clinical characteristics and prognostic factors of visual and survival outcomes in septic CST is warranted to contemporize current understanding and help guide management. METHODS: A multicentered retrospective cohort study was conducted at 2 tertiary care centers using an electronic medical record search of the term, "thrombosis of cavernous venous sinus" between January 1, 2000, and December 31, 2021. Inclusion criteria consisted of active infection and radiographic evidence of associated CST. Demographic and clinical data extracted included age at presentation, sex, infection type and extent, and ophthalmic examination findings at presentation-best-corrected visual acuity (BCVA), presence of relative afferent pupillary defect (RAPD), intraocular pressure (IOP), and extraocular motility (EOM) limitation. Management data collected consisted of type and length of antimicrobial therapy, type and length of anticoagulation administration, and surgical intervention. Primary outcomes assessed were ophthalmic examination findings at final evaluation and same-hospitalization mortality. RESULTS: A total of 27 patients with imaging-confirmed septic CST were identified at 2 tertiary care centers. At presentation, 2 (8.7%) patients had no light perception (NLP) vision, 8 (29.6%) patients had RAPD, 17 (73.9%) patients had EOM limitation, and 13 (54.2%) had IOP >21 mm Hg. All patients received antimicrobial therapy, with vancomycin being the most common agent. Fifteen patients (55.6%) received anticoagulation, and 21 (81.5%) patients underwent surgical intervention. Same-hospitalization mortality was 3 (11.1%). Among the 21 patients with ophthalmic data at follow-up, 3 (16.7%) had NLP vision, 5 (23.8%) had a persistent RAPD, 7 (31.8%) had persistent EOM limitation, and no patients had IOP elevated above 21 mm Hg. Patients with RAPD at presentation had significantly worse BCVA at final evaluation (logMAR BCVA 1.43 higher on average, P = 0.01) and a significantly higher mortality rate (37.5% vs. 0.0%, P < 0.01) than non-RAPD patients. Demographic features, BCVA at presentation, EOM limitation at presentation, elevated IOP at presentation, and comorbid orbital cellulitis were not associated with worse visual or mortality outcomes. CONCLUSIONS: Septic CST may result in permanent ophthalmic functional deficit in almost one-third of cases and mortality in approximately 11% of patients under contemporary management. New RAPD at presentation may indicate higher risk of poor visual and survival outcomes.

Older Woman With Proptosis, Ptosis, and Blurred Vision.

A woman in her early 70s with a history of coronary artery disease, hypertension, and colon polyps presented to oculoplastic surgery with 1 week of progressive right-sided proptosis, headache, right eyelid ptosis, and blurry vision. Outside magnetic resonance imaging demonstrated an infiltrative mass involving right greater than left orbital apices, the right optic nerve, and right extraocular muscles. What would you do next?

Subperiosteal and Orbital Abscesses: A Comparison of Clinical Features, Management, and Outcomes.

PURPOSE: To compare the clinical features, management, and outcomes between orbital cellulitis patients with subperiosteal abscess (SPA) and those with orbital abscess (OA). METHODS: A retrospective study was conducted at a tertiary care center through medical record search to identify patients with orbital cellulitis from January 1, 2000 to December 31, 2022. Charts were screened for those with radiographic evidence of SPA or OA. Demographic data and presenting clinical features were compared between the 2 cohorts. Primary outcomes compared included rates of surgical intervention, reoperation, and readmission; and length of hospital stay and final vision. RESULTS: A total of 189 patients, 162 with SPA and 27 with OA, met the criteria. The OA group (mean 46.5 ± 18.6 years) was older than the SPA group (mean 19.1 ± 21.4 years). Comorbid sinusitis was significantly more common in the SPA cohort (95.7% SPA; 70.4% OA; p < 0.001), while OA was more likely to occur with orbital trauma (29.6% vs. 8.0%; p = 0.003), implanted hardware (11.1% vs. 0.6%; p = 0.005), and comorbid diabetes (22.2% vs. 4.3%; p = 0.001). OA patients more often presented with a relative afferent pupillary defect (21.7% vs. 3.9%; p = 0.005), vision worse than 20 of 50 (42.3% vs. 16.2%; p = 0.005), and methicillin-resistant Staphylococcus aureus infection (20.8% vs. 5.8%; p = 0.036). OA was associated with a higher reoperation rate (47.8% vs. 21.3%; p = 0.019), readmission rate (18.5% vs. 5.6%, p = 0.047), and limited extraocular motility at follow-up (4.3% vs. 25%; p = 0.013); while mean length of hospital stay and final visual acuity were similar. CONCLUSION: OA may affect an older population with a divergent risk factor profile compared with SPA. OA may cause more severe functional impairment on presentation, warranting more aggressive management to achieve visual outcomes similar to SPA.

Evaluation of a STAT MRI Protocol for Emergent Ophthalmology Patients.

BACKGROUND: Evaluating patients with potentially sight-threatening conditions frequently involves urgent neuroimaging, and some providers recommend expediting emergency department (ED) evaluation. However, several factors may limit the practicality of ED evaluation. This pilot study assessed the feasibility and safety of a STAT magnetic resonance imaging (MRI) protocol, designed to facilitate outpatient MRI within 48 hours of referral, compared with ED evaluation for patients with optic disc edema. METHODS: A retrospective chart review was performed. Demographics, clinical data, and baseline ophthalmic measures were compared between patients in STAT and ED groups using the t test or Fisher exact test. Multivariate analyses compared changes in visual acuity (VA), visual field mean deviation (VF MD), retinal nerve fiber layer thickness, and edema grade between presentation and follow-up using a mixed-effects model adjusting for age, sex, and baseline measures. RESULTS: A total of 70 patients met the study criteria-24 (34.3%) in the STAT MRI cohort and 46 (65.7%) in the ED cohort. Demographic variables were similar between groups. Patients referred to the ED had worse VA ( P < 0.001), larger VF MD ( P < 0.001), and higher edema grade ( P = 0.002) at presentation. Four patients in the ED group and none in the STAT group were found to have space-occupying lesions. Multivariate analyses showed that follow-up measures were significantly associated with their baseline values (all P < 0.001) but not with referral protocol (all P > 0.099). The STAT MRI protocol was associated with lower average patient charges and hospital costs. CONCLUSIONS: The STAT MRI protocol did not result in inferior visual outcomes or delay in life-threatening diagnoses. Urgent outpatient evaluation, rather than ED referral, seems safe for some patients with optic disc edema. These findings support continued utilization of the protocol and ongoing improvement efforts.

In-Depth Analysis of Preoperative OCT Markers as Prognostic Factors for Lamellar Macular Holes and Epiretinal Membrane Foveoschisis.

OBJECTIVE: To identify preoperative OCT markers that correlate with postoperative visual acuity (VA) changes in eyes with lamellar macular hole (LMH) and epiretinal membrane foveoschisis (ERMF) after pars plana vitrectomy (PPV). DESIGN: Cross-sectional retrospective study. SUBJECTS: Patients seen at the Wilmer Eye Institute between 2011 and 2021 with an International Classification of Diseases, Ninth Revision, or International Classification of Diseases, 10th Revision, code for "macular hole" that underwent PPV, and demonstrated all OCT criteria present for either LMH or ERMF based on the Hubschman et al (2020) classification. METHODS: Optical coherence tomography markers including hole dimensions, retinal layer continuity, and ellipsoid zone (EZ) convexity and pixelated intensity were quantified. Visual acuity immediately before PPV and at the last follow-up date available were both recorded. MAIN OUTCOME MEASURES: Preoperative OCT variables that are correlated with postoperative changes in VA. RESULTS: Forty-two eyes from 42 patients with LMH (n = 11) and ERMF (n = 31) that underwent PPV were identified. Visual acuity in the ERMF cohort significantly improved at last follow-up compared with preoperative VA (P < 0.001), whereas VA in the LMH cohort did not (P = 0.14). In the LMH cohort, retinal layer continuity at the hole edge was positively correlated with change in VA at final follow-up, whereas hole height was negatively correlated with VA. In the ERMF cohort, preoperative VA was negatively correlated with change in VA at final follow-up. CONCLUSIONS: Retinal layer continuity at the hole and hole height are novel preoperative markers that predict postoperative VA change in LMH. After identifying the type of macular lesion, surgeons should consider using these preoperative OCT markers when counseling patients on potential postoperative VA outcomes and when managing patient expectations.

Microbiology and Antibiotic Resistance Profiles of Orbital Subperiosteal Abscesses: A Comparison of Pediatric, Adolescent, and Adult Populations.

PURPOSE: The purpose of this study was to compare the microbiology and antibiotic resistance profiles of orbital subperiosteal abscesses (SPA) among 3 age cohorts. METHODS: A retrospective study was conducted at a tertiary care center through a medical record search to identify patients with orbital cellulitis and SPA on imaging from January 1, 2000 to September 10, 2022. Patients were categorized into pediatric (<9 years old), adolescent (9-18 years old), and adult (>18 years old) cohorts. Primary outcomes included culture and antibiotic susceptibility results. Secondary outcomes included antibiotic therapy and surgical intervention. RESULTS: Of the 153 SPA patients included, 62 (40.5%) were in the pediatric cohort (4 months-8 years, mean 5.0 ± 2.7), 51 (33.3%) were adolescent (9-18 years, 12.7 ± 2.8), and 40 (26.1%) were adult (19-95, 51.8 ± 19.3). Viridians group Streptococci were the most frequent organisms isolated across groups. The anaerobic infection rate was higher in the adult compared to the pediatric group (23.0% vs, 4.0%, p = 0.017), while that of the adolescent did not differ significantly from either. Pediatric patients carried a lower rate of clindamycin resistance than adolescent and adult cohorts, who shared similar rates (0 vs. 27.0% and 28.0%, respectively; p = 0.016). There were progressive increases in duration of intravenous antibiotic therapy ( p < 0.195) and rate of surgical intervention ( p < 0.001) going from younger to older cohorts. CONCLUSION: Organisms isolated from orbital SPA from the past 2 decades demonstrate a predominance of Streptococcal species. Older age may be associated with anaerobic infection, clindamycin resistance, and more aggressive management. Adolescent infections are more similar to adult rather than pediatric counterparts but may require less aggressive management than the former.

The Emotional and Personal Experiences of the COVID-19 Illness During the Early Pandemic: A Qualitative Study.

BACKGROUND: Several studies report the incidence of psychiatric symptoms and disorders among patients who recovered from coronavirus disease 2019 (COVID-19); however, little is known about the emotional impact of acute COVID-19 illness and recovery on these survivors. Qualitative methods are ideal for understanding the psychological impact of a novel illness. OBJECTIVE: To describe the emotional experience of the acute COVID-19 illness and recovery in patients who contracted the virus during the early months of the pandemic. METHODS: Semi-structured interviews conducted by consultation-liaison (C-L) psychiatrists were used to elicit participant responses about the emotional impact of the acute and recovery phases of the COVID-19 illness. Participants recruited from the Maryland, District of Columbia, and Virginia area were interviewed which was audio recorded between June 2020 and December 2020. The research team extracted qualitative themes from the recordings using the principles of thematic analysis. RESULTS: One hundred and one COVID-19 survivors (54 women; mean [SD] age, 50 [14.7] years) were interviewed at a mean of 5.16 months after their acute illness, and their responses were audio-recorded. Most participants were White (77%), non-Hispanic/Latino (86.1%), and not hospitalized for COVID-19 (87.1%). Coders identified 26 themes from participant responses. The most frequently coded themes included anxiety/worry (49), uncertainty (37), supportfrom others (35), alone/isolation (32), and positive reframe/positive emotions (32). CONCLUSIONS: Survivors who contracted severe acute respiratory syndrome coronavirus 2 during the early months of the pandemic described both negative and positive valence emotions. They experienced emotional distress and psychosocial stressors associated with the acute illness and recovery but also drew upon personal resiliency to cope. This report highlights the utility of qualitative research methods in identifying emotional responses to a novel illness that may otherwise go unnoted. Consultation-liaison psychiatrists may be uniquely positioned to work in collaboration with medical colleagues in developing a multidimensional approach to evaluating an emerging illness.

Examining the factor structure of the DSM-5 Level 1 cross-cutting symptom measure.

OBJECTIVES: The DSM-5 Level 1 Cross-Cutting Symptom Measure (DSM-XC) was developed by the American Psychiatric Association as a transdiagnostic mental health symptom survey. Despite its promise as a screening tool, few studies have assessed its latent dimensionality or provided guidance on interpreting responses. We examined the factor structure of the DSM-XC in a convenience sample of participants with varying degrees of psychopathology. METHODS: Participants (n = 3533) were enrolled in an online study on the mental health impact of COVID-19 (NCT04339790). We used a factor analytic framework with exploratory and confirmatory analyses to evaluate candidate factor solutions. Convergent validity analysis with concurrent study measures was also performed. RESULTS: Six-factor and bifactor candidate solutions both had good fit and full measurement invariance across age, sex, and enrollment date. The six-factor solution resulted in constructs labeled as: mood, worry, activation, somatic, thought, and substance use. A general psychopathology factor and two residual factors (mood and anxiety constructs) explained the variance of the bifactor solution. CONCLUSIONS: Our analysis supports that the DSM-XC is a multidimensional instrument spanning many mental health symptoms. We provide scoring solutions for two factor structures that capture broader constructs of psychopathology. Use of a convenience sample may limit generalizability of findings.

The NIMH intramural healthy volunteer dataset: A comprehensive MEG, MRI, and behavioral resource.

The NIMH Healthy Research Volunteer Dataset is a collection of phenotypic data characterizing healthy research volunteers using clinical assessments such as assays of blood and urine, mental health assessments, diagnostic and dimensional measures of mental health, cognitive and neuropsychological functioning, structural and functional magnetic resonance imaging (MRI), along with diffusion tensor imaging (DTI), and a comprehensive magnetoencephalography battery (MEG). In addition, blood samples of healthy volunteers are banked for future analyses. All data collected in this protocol are broadly shared in the OpenNeuro repository, in the Brain Imaging Data Structure (BIDS) format. In addition, task paradigms and basic pre-processing scripts are shared on GitHub. There are currently few open access MEG datasets, and multimodal neuroimaging datasets are even more rare. Due to its depth of characterization of a healthy population in terms of brain health, this dataset may contribute to a wide array of secondary investigations of non-clinical and clinical research questions.

The utility of self-perceived health ratings in screening volunteers for mental health research.

We report on the utility of online self-perceived medical and mental health ratings (SPH) when screening healthy volunteers for mental health research. These one-item ratings were correlated with eligibility decisions and longer clinical surveys. We found correlations between SPH ratings and blinded clinician ratings of volunteer medical and mental health after an in-person evaluation, although additional analysis revealed poor reliability between clinician and volunteer ratings. SPH ratings are a useful addition to screening methods for research studies.

COVID-19 and Mental Health: Predicted Mental Health Status is Associated with Clinical Symptoms and Pandemic-Related Psychological and Behavioral Responses.

BACKGROUND: The COVID-19 pandemic led to dramatic threats to health and social life. Study objectives - develop a prediction model leveraging subsample of known Patient/Controls and evaluate the relationship of predicted mental health status to clinical outcome measures and pandemic-related psychological and behavioral responses during lockdown (spring/summer 2020). METHODS: Online cohort study conducted by National Institute of Mental Health Intramural Research Program. Convenience sample of English-speaking adults (enrolled 4/4-5/16/20; n=1,992). Enrollment measures: demographics, clinical history, functional status, psychiatric and family history, alcohol/drug use. Outcome measures (enrollment and q2 weeks/6 months): distress, loneliness, mental health symptoms, and COVID-19 survey. NIMH IRP Patient/Controls survey responses informed assignment of Patient Probability Scores (PPS) for all participants. Regression models analyzed the relationship between PPS and outcome measures. OUTCOMES: Mean age 46.0 (±14.7), female (82.4%), white (88.9 %). PPS correlated with distress, loneliness, depression, and mental health factors. PPS associated with negative psychological responses to COVID-19. Worry about mental health (OR 1.46) exceeded worry about physical health (OR 1.13). PPS not associated with adherence to social distancing guidelines but was with stress related to social distancing and worries about infection of self/others. INTERPRETATION: Mental health status (PPS) was associated with concurrent clinical ratings and COVID-specific negative responses. A focus on mental health during the pandemic is warranted, especially among those with mental health vulnerabilities. We will include PPS when conducting longitudinal analyses of mental health trajectories and risk and resilience factors that may account for differing clinical outcomes. FUNDING: NIMH (ZIAMH002922); NCCIH (ZIAAT000030).

Examining the Factor Structure of the DSM-5 Level 1 Cross-Cutting Symptom Measure.

OBJECTIVES: The DSM-5 Level 1 Cross-Cutting Symptom Measure (DSM-XC) is a transdiagnostic mental health symptom measure that has shown promise in informing clinical diagnostic evaluations and as a screening tool for research. However, few studies have assessed the latent dimensionality of the DSM-XC. We examined the factor structure of the DSM-XC in a large convenience sample of participants with varying degrees of psychological health. METHODS: Participants (n=3533) enrolled in a protocol conducted at the National Institute of Mental Health (NCT04339790). We used a factor analytic framework to evaluate an existing two-factor solution (Lace & Merz, 2020) and two additional candidate solutions. RESULTS: The Lace and Merz solution had acceptable fit. Exploratory factor analysis yielded two candidate solutions: a six-factor (characterized as mood, worry, activation, somatic, thoughts, and substance use) and a bifactor (general factor of non-specific psychopathology, residual factors characterized as internalizing and thought disorder), which both had good fit and full measurement invariance across age, sex, and enrollment date. CONCLUSIONS: Our findings confirm that the DSM-XC may be conceptualized as a multidimensional instrument and provide a scoring solution for researchers who wish to measure distinct constructs. Future research on the psychometric profile of the DSM-XC is needed, focused on the validity of these candidate solutions and their performance across research populations and settings.

Towards a neurobiology of female aggression.

Although many people think of aggression as a negative or undesirable emotion, it is a normal part of many species' repertoire of social behaviors. Purposeful and controlled aggression can be adaptive in that it warns other individuals of perceived breaches in social contracts with the goal of dispersing conflict before it escalates into violence. Aggression becomes maladaptive, however, when it escalates inappropriately or impulsively into violence. Despite ample data demonstrating that impulsive aggression and violence occurs in both men and women, aggression has historically been considered a uniquely masculine trait. As a result, the vast majority of studies attempting to model social aggression in animals, particularly those aimed at understanding the neural underpinnings of aggression, have been conducted in male rodents. In this review, we summarize the state of the literature on the neurobiology of social aggression in female rodents, including social context, hormonal regulation and neural sites of aggression regulation. Our goal is to put historical research in the context of new research, emphasizing studies using ecologically valid methods and modern sophisticated techniques. This article is part of the Special Issue entitled 'Current status of the neurobiology of aggression and impulsivity'.
