To evaluate the impact of receptive vocabulary versus years of education on neuropsychological performance of Black and White older adults.

A community-based prospectively enrolled cohort (n = 1,007; 130 Black, 877 White) in the Emory Healthy Brain Study were administered the NIH Toolbox Picture Vocabulary Test and neuropsychological measures. Group differences were evaluated with age, sex, and education or age, sex, and Toolbox Vocabulary scores as covariates to determine whether performance differences between Black versus White participants were attenuated or eliminated.

With vocabulary as a covariate, the main effect of race was no longer significant for the MoCA, Phonemic Fluency, Rey Auditory Verbal Learning Test, and Rey Complex Figure Test immediate and delayed recall. Although still significantly different between groups, the effect sizes for Animal Fluency, Trails B-A, Symbol Digit Modalities Test, and Rey Copy were attenuated, with the greatest reductions occurring for the Multilingual Naming Test and Judgment of Line Orientation.

Findings support the value of using receptive vocabulary as a proxy for premorbid ability level when comparing the cognitive performance of Black and White older adults. The results extend investigations using measures of single word reading to encompass measures assessing word meaning.

To introduce the Emory 10-element Complex Figure (CF) scoring system and recognition task. We evaluated the relationship between Emory CF scoring and traditional Osterrieth CF scoring approach in cognitively healthy volunteers. Additionally, a cohort of patients undergoing deep brain stimulation (DBS) evaluation was assessed to compare the scoring methods in a clinical population.

The study included 315 volunteers from the Emory Healthy Brain Study (EHBS) with Montreal Cognitive Assessment (MoCA) scores of 24/30 or higher. The clinical group consisted of 84 DBS candidates. Scoring time differences were analyzed in a subset of 48 DBS candidates.

High correlations between scoring methods were present for non-recognition components in both cohorts (EHBS: Copy r = 0.76, Immediate r = 0.86, Delayed r = 0.85, Recognition r = 47; DBS: Copy r = 0.80, Immediate r = 0.84, Delayed Recall r = 0.85, Recognition r = 0.37). Emory CF scoring times were significantly shorter than Osterrieth times across non-recognition conditions (all p < 0.00001, individual Cohen’s d: 1.4–2.4), resulting in an average time savings of 57%. DBS patients scored lower than EHBS participants across CF memory measures, with larger effect sizes for Emory CF scoring (Cohen’s d range = 1.0–1.2). Emory CF scoring demonstrated better group classification in logistic regression models, improving DBS candidate classification from 16.7% to 32.1% compared to Osterrieth scoring.

Emory CF scoring yields results that are highly correlated with traditional Osterrieth scoring, significantly reduces scoring time burden, and demonstrates greater sensitivity to memory decline in DBS candidates. Its efficiency and sensitivity make Emory CF scoring well-suited for broader implementation in clinical research.

Understanding characteristics of healthcare personnel (HCP) with SARS-CoV-2 infection supports the development and prioritization of interventions to protect this important workforce. We report detailed characteristics of HCP who tested positive for SARS-CoV-2 from April 20, 2020 through December 31, 2021.

CDC collaborated with Emerging Infections Program sites in 10 states to interview HCP with SARS-CoV-2 infection (case-HCP) about their demographics, underlying medical conditions, healthcare roles, exposures, personal protective equipment (PPE) use, and COVID-19 vaccination status. We grouped case-HCP by healthcare role. To describe residential social vulnerability, we merged geocoded HCP residential addresses with CDC/ATSDR Social Vulnerability Index (SVI) values at the census tract level. We defined highest and lowest SVI quartiles as high and low social vulnerability, respectively.

Our analysis included 7,531 case-HCP. Most case-HCP with roles as certified nursing assistant (CNA) (444, 61.3%), medical assistant (252, 65.3%), or home healthcare worker (HHW) (225, 59.5%) reported their race and ethnicity as either non-Hispanic Black or Hispanic. More than one third of HHWs (166, 45.2%), CNAs (283, 41.7%), and medical assistants (138, 37.9%) reported a residential address in the high social vulnerability category. The proportion of case-HCP who reported using recommended PPE at all times when caring for patients with COVID-19 was lowest among HHWs compared with other roles.

To mitigate SARS-CoV-2 infection risk in healthcare settings, infection prevention, and control interventions should be specific to HCP roles and educational backgrounds. Additional interventions are needed to address high social vulnerability among HHWs, CNAs, and medical assistants.

The Rey Complex Figure (CF) is a popular test to assess visuospatial construction and visual memory, but its broader use in clinical research is limited by scoring complexity. To widen its application, we developed a new CF scoring system similar to the Benson Figure in which 10 primary CF elements are scored according to presence and location. A novel recognition task was also created for each of these 10 items consisting of a 4-choice recognition condition containing the primary rectangle and major interior lines with qualitative variations of target elements as distractors. The current investigation was designed to characterize the relationship between scoring methods and establish whether comparable results are obtained across both traditional and new CF scoring approaches.

Participants from the Emory Health Brain Study (EHBS) who had completed the Rey CF copy during their cognitive study visit were studied. All participants were self-identified as normal, and administered the CF according to our previously published procedure that included the Copy, Immediate Recall (∼ 30 seconds), and 30-minute Delayed Recall (Loring et al., 1990). Following delayed recall, CF recognition was assessed using the Meyers and Myers (1995) recognition followed by the newly developed forced choice recognition. The final sample included 155 participants ranging in age from 51.6 years to 80.0 years (M=64.9, SD=6.6). The average MoCA score was 26.8/30 (SD=6.6).

Mean performance levels across conditions and scoring approaches are included in the table. Correlations between Copy, Immediate Recall, Delayed Recall, and Recognition were calculated to evaluate the relationship between the traditional 18 item/36 point Osterrieth criteria and newly developed CF scoring criteria using both parametric and non-parametric approaches. Pearson correlations demonstrated high agreement between approaches when characterizing performance levels across all CF conditions (Copy r=.72, Immediate Recall r=.87, Delayed Recall r=.90, and Recognition r=.52). Similar correlations were present using non-parametric analyses (Copy ρ=.46, Immediate Recall ρ=.83, Delayed Recall ρ=.91, and Recognition ρ=.42). Table. Mean performance levels across conditions and scoring approaches

The high correlations, particularly for Immediate and Delayed Recall conditions, suggest that the modified simpler scoring system is comparable to the traditional approach, thereby suggesting potential equivalence between scoring methods. When comparing Rey’s original 47 point scoring approach to his 36 point scoring system, Osterrieth (1944) reported a correlation in fifty adults of ρ=.95 and a correlation in twenty 6-year-olds of ρ=.92. In this investigation, lower correlations were observed for copy and recognition conditions, in part representing smaller response distribution across participants. Although these preliminary results are encouraging, to implement the new EHBS scoring method in clinical evaluation, we are developing normative data in participants across the entire EHBS series, many of whom were not administered the new CF Recognition. We are also examining performances in patients undergoing DBS evaluation for Parkinson Disease to explore its clinical sensitivity. Simpler scoring will permit greater CF clinical and research application.

Arachnoid cysts are fluid-filled sacs thought to be a developmental abnormality which form as a result of splitting or duplication of the arachnoid membrane. In most cases, arachnoid cysts are congenital and asymptomatic throughout an individual’s life. Rarely, arachnoid cysts develop because of head injury, intraventricular hemorrhage of prematurity, presence of a tumor, infection or surgery on the brain. Intracranial cysts are typically incidental brain imaging findings and most commonly located in the middle fossa, the suprasellar region, and the posterior fossa. In cases where the cyst enlarges significantly individuals may experience symptoms of increased intracranial pressure, mass effects, seizures, nausea and vomiting, focal neurological deficits, or hydrocephalus. This presentation compares the differing symptom presentation of two individuals with medically confirmed arachnoid cysts -- one in the middle cranial fossa region (Patient A) and the other in the posterior cranial fossa region (Patient B).

The 2 patients were referred to a private practice neuropsychological clinic for neuropsychological assessment. Patient A was a 39-year-old, right-handed, married Syrian male with 12 years if education, unemployed at the time of testing. Changes in cognition, behavior and personality were reported for Patient A approximately two years after a known cerebrovascular accident. Patient B was a 48-year-old, left-handed married Caucasian male with 16 years of education, on disability due to his medical condition. Patient B reported severe memory impairment, speech and language deficits, variable attention, executive dysfunction, impaired gait with falls, emotional dysregulation, and sleep difficulties. He was diagnosed with bipolar disorder and alcohol use disorder in remission for 9 years.

Neuropsychological testing results for Patient A were not valid, due to initiation difficulties, paranoia about the testing and consequent limited engagement in the process. Predominant symptoms were consistent with negative symptoms of schizophrenia, (i.e., avolition, abulia, and diminished emotional expression); no positive symptoms were observed or reported. His speech was limited -he lacked spontaneous speech and only responded to direct questions. His informant completed a measure assessing pre/post changes in frontal systems and there were significant increases in apathy and executive dysfunction reported. Neuropsychological results collected from Patient B revealed mild to severe impairment of aspects of executive functioning, memory, processing speed, visual attention, expressive language, and manual dexterity bilaterally and manual motor strength - more consistent with subcortical neurological disease. Self-report and informant data revealed significant difficulties with functional abilities, pre/post changes in frontal systems (apathy, disinhibition, and executive dysfunction), sleep efficiency and daytime fatigue, and psychological distress (anxiety and depressive symptoms).

The presenting case analysis illustrates the importance of neuropsychology in identifying and tracking the nature of symptoms associated with neuroimaging confirmed arachnoid cysts. This case analysis is unique as it highlights the complexities of differing symptom phenotypes of the same condition due to location of the cyst. Surgical intervention usually through draining the cyst directly or implantation of a shunt is typically recommended for symptomatic patients and that course of treatment was suggested to both patients. Treatment recommendations geared to target psychosocial and functional difficulties should also be considered.

Several hypotheses may explain the association between substance use, posttraumatic stress disorder (PTSD), and depression. However, few studies have utilized a large multisite dataset to understand this complex relationship. Our study assessed the relationship between alcohol and cannabis use trajectories and PTSD and depression symptoms across 3 months in recently trauma-exposed civilians.

In total, 1618 (1037 female) participants provided self-report data on past 30-day alcohol and cannabis use and PTSD and depression symptoms during their emergency department (baseline) visit. We reassessed participant's substance use and clinical symptoms 2, 8, and 12 weeks posttrauma. Latent class mixture modeling determined alcohol and cannabis use trajectories in the sample. Changes in PTSD and depression symptoms were assessed across alcohol and cannabis use trajectories via a mixed-model repeated-measures analysis of variance.

Three trajectory classes (low, high, increasing use) provided the best model fit for alcohol and cannabis use. The low alcohol use class exhibited lower PTSD symptoms at baseline than the high use class; the low cannabis use class exhibited lower PTSD and depression symptoms at baseline than the high and increasing use classes; these symptoms greatly increased at week 8 and declined at week 12. Participants who already use alcohol and cannabis exhibited greater PTSD and depression symptoms at baseline that increased at week 8 with a decrease in symptoms at week 12.

Our findings suggest that alcohol and cannabis use trajectories are associated with the intensity of posttrauma psychopathology. These findings could potentially inform the timing of therapeutic strategies.

Among patients with a history of ESBL infection, uncertainty remains regarding whether all of these patients require ESBL-targeted therapy when presenting with a subsequent infection. We sought to determine the risks associated with a subsequent ESBL infection to help inform empiric antibiotic decisions.

A retrospective cohort study of adult patients with positive index culture for Escherichia coli or Klebsiella pneumoniae (EC/KP) receiving medical care during 2017 was conducted. Risk assessments were performed to identify factors associated with subsequent infection caused by ESBL-producing EC/KP.

In total, 200 patients were included in the cohort, 100 with ESBL-producing EC/KP and 100 with ESBL-negative EC/KP. Of 100 patients (50%) who developed a subsequent infection, 22 infections were ESBL-producing EC/KP, 43 were other bacteria, and 35 had no or negative cultures. Subsequent infection caused by ESBL-producing EC/KP only occurred when the index culture was also ESBL-producing (22 vs 0). Among those with ESBL-producing index culture, the incidences of subsequent infection caused by ESBL-producing EC/KP versus other bacterial subsequent infection were similar (22 vs 18; P = .428). Factors associated with subsequent infection caused by ESBL-producing EC/KP include history of ESBL-producing index culture, time ≤180 days between index culture and subsequent infection, male sex, and Charlson comorbidity index score >3.

History of ESBL-producing EC/KP culture is associated with subsequent infection caused by ESBL-producing EC/KP, particularly within 180 days after the historical culture. Among patients presenting with infection and a history of ESBL-producing EC/KP, other factors should be considered in making empiric antibiotic decisions, and ESBL-targeted therapy may not always be warranted.

The Residual Lesion Score is a novel tool for assessing the achievement of surgical objectives in congenital heart surgery based on widely available clinical and echocardiographic characteristics. This article describes the methodology used to develop the Residual Lesion Score from the previously developed Technical Performance Score for five common congenital cardiac procedures using the RAND Delphi methodology.

A panel of 11 experts from the field of paediatric and congenital cardiology and cardiac surgery, 2 co-chairs, and a consultant were assembled to review and comment on validity and feasibility of measuring the sub-components of intraoperative and discharge Residual Lesion Score for five congenital cardiac procedures. In the first email round, the panel reviewed and commented on the Residual Lesion Score and provided validity and feasibility scores for sub-components of each of the five procedures. In the second in-person round, email comments and scores were reviewed and the Residual Lesion Score revised. The modified Residual Lesion Score was scored independently by each panellist for validity and feasibility and used to develop the “final” Residual Lesion Score.

The Residual Lesion Score sub-components with a median validity score of ≥7 and median feasibility score of ≥4 that were scored without disagreement and with low absolute deviation from the median were included in the “final” Residual Lesion Score.

Using the RAND Delphi methodology, we were able to develop Residual Lesion Score modules for five important congenital cardiac procedures for the Pediatric Heart Network’s Residual Lesion Score study.

The optimal timing of surgical repair for infants with complete atrioventricular canal defect remains controversial, as there are risks to both early and late repair. We address this debate by investigating the association of various risk factors, including age and weight at surgery, markers of failure to thrive, and pulmonary vascular disease, with postoperative length of stay following complete atrioventricular canal repair.

Infants who underwent repair of complete atrioventricular canal were identified from our institutional Society of Thoracic Surgeons Congenital Heart Surgery Database. Additional clinical data were collected from the electronic medical record. Descriptive statistics were computed. Associations between postoperative length of stay and covariates of interest were evaluated using linear regression with bootstrap aggregation.

From 2001 to 2020, 150 infants underwent isolated complete atrioventricular canal repair at our institution. Pre-operative failure to thrive and evidence of pulmonary disease were common. Surgical mortality was 2%. In univariable analysis, neither weight nor age at surgery were associated with mortality, postoperative length of stay, duration of mechanical ventilation, or post-operative severe valvular regurgitation. In multivariable analysis of demographic and preoperative clinical factors using bootstrap aggregation, increased postoperative length of stay was only significantly associated with previous pulmonary artery banding (33.9 day increase, p = 0.03) and preoperative use of supplemental oxygen (19.9 day increase, p = 0.03).

Our analysis shows that previous pulmonary artery banding and preoperative use of supplemental oxygen were associated with increased postoperative length of stay after complete atrioventricular canal repair, whereas age and weight were not. These findings suggest operation prior to the onset of pulmonary involvement may be more important than reaching age or weight thresholds.
