RESUMEN

Monkeypox, a zoonotic infection caused by an orthopoxvirus, is endemic in parts of Africa. On August 4, 2022, the U.S. Department of Health and Human Services declared the U.S. monkeypox outbreak, which began on May 17, to be a public health emergency (1,2). After detection of the first U.S. monkeypox case), CDC and health departments implemented enhanced monkeypox case detection and reporting. Among 2,891 cases reported in the United States through July 22 by 43 states, Puerto Rico, and the District of Columbia (DC), CDC received case report forms for 1,195 (41%) cases by July 27. Among these, 99% of cases were among men; among men with available information, 94% reported male-to-male sexual or close intimate contact during the 3 weeks before symptom onset. Among the 88% of cases with available data, 41% were among non-Hispanic White (White) persons, 28% among Hispanic or Latino (Hispanic) persons, and 26% among non-Hispanic Black or African American (Black) persons. Forty-two percent of persons with monkeypox with available data did not report the typical prodrome as their first symptom, and 46% reported one or more genital lesions during their illness; 41% had HIV infection. Data suggest that widespread community transmission of monkeypox has disproportionately affected gay, bisexual, and other men who have sex with men and racial and ethnic minority groups. Compared with historical reports of monkeypox in areas with endemic disease, currently reported outbreak-associated cases are less likely to have a prodrome and more likely to have genital involvement. CDC and other federal, state, and local agencies have implemented response efforts to expand testing, treatment, and vaccination. Public health efforts should prioritize gay, bisexual, and other men who have sex with men, who are currently disproportionately affected, for prevention and testing, while addressing equity, minimizing stigma, and maintaining vigilance for transmission in other populations. Clinicians should test patients with rash consistent with monkeypox,† regardless of whether the rash is disseminated or was preceded by prodrome. Likewise, although most cases to date have occurred among gay, bisexual, and other men who have sex with men, any patient with rash consistent with monkeypox should be considered for testing. CDC is continually evaluating new evidence and tailoring response strategies as information on changing case demographics, clinical characteristics, transmission, and vaccine effectiveness become available.§.

RESUMEN

Houses have often been used as comparison stimuli in face-processing studies because of the many attributes they share with faces (e.g., distinct members of a basic category, consistent internal features, mono-orientation, and relative familiarity). Despite this, no large, well-controlled databases of photographs of houses that have been developed for research use currently exist. To address this gap, we photographed 100 houses and carefully edited these images. We then asked 41 undergraduate students (18 to 31 years of age) to rate each house on three dimensions: typicality, likeability, and face-likeness. The ratings had a high degree of face validity, and analyses revealed a significant positive correlation between typicality and likeability. We anticipate that this stimulus set (i.e., the DalHouses) and the associated ratings will prove useful to face-processing researchers by minimizing the effort required to acquire stimuli and allowing for easier replication and extension of studies. The photographs of all 100 houses and their ratings data can be obtained at http://dx.doi.org/10.6084/m9.figshare.1279430.

RESUMEN

Math difficulties (MDs) occur in about 3-7 % of children and have been associated with academic, health, and occupational challenges. To date, findings about the role of working memory in MDs have been conflicting. The Automated Working Memory Assessment Battery (AWMA), which assesses all components of Baddeley and Hitch's model of working memory, was used to investigate which component of the model was most related to math calculation skills in elementary-school children. Participants were 94 (52 male) children (M age = 9 years 1 month; Range = 6 years 0 months to 11 years 8 months). As hypothesized, math calculation scores were correlated with all four working memory components (phonological loop, visuospatial sketchpad, verbal and visuospatial central executive). After accounting for age, phonological processing, and attention, the visuospatial sketchpad was the only memory component that contributed to the prediction of math calculation scores, explaining an additional 10.2 % of unique variance. Short-term visuospatial memory should be assessed in children having difficulty with math and children could benefit from interventions that include attention to the development of both visuospatial memory and math calculation skills. This study did not use a longitudinal design and so we cannot conclude that weak visuospatial memory impedes the development of math calculation skills. Future research should use longitudinal designs and investigate other types of math skills.

RESUMEN

Gaze direction plays a central role in face recognition. Previous research suggests that faces with direct gaze are better remembered than faces with averted gaze. We compared recognition of faces with direct versus averted gaze in male versus female participants. A total of 52 adults (23 females, 29 males) and 46 children (25 females, 21 males) completed a computerised task that assessed their recognition of faces with direct gaze and faces with averted gaze. Adult male participants showed superior recognition of faces with direct gaze compared to faces with averted gaze. There was no difference between recognition of direct and averted gaze faces for the adult female participants. Children did not demonstrate this sex difference; rather, both male and female youth participants showed better recognition of faces with direct gaze compared to averted gaze. A large body of previous research has revealed superior recognition of faces with direct, compared to averted gaze. However, relatively few studies have examined sex differences. Our findings suggest that gaze direction has differential effects on face recognition for adult males and females, but not for children. These findings have implications for previous explanations of better recognition for direct versus averted gaze.

RESUMEN

Objective: This paper lends a critical eye to six common assumptions/biases about autism that may influence neuropsychologists in their clinical work. These biases are based on research as well as the historical roots of the study of autism. Our goal is to encourage curiosity and reflection on these biases in order to improve neuropsychological service delivery for people on the autism spectrum. Methods: We argue that psychologists should strive to understand the function of behaviours observed with autism in order to offer helpful supports. We explore the assertions that autism is not a dichotomous or linear construct and that the use of high and low functioning descriptors are not useful nor appreciated by the autism community. We discuss the widely held beliefs that individuals on the autism spectrum lack theory of mind, empathy and social motivation. Importantly, people on the autism spectrum are telling us that the dialogue about them around theory of mind and empathy is a human rights issue. Finally, we discuss the role of standardized testing. Conclusions: Through an exploration of research literature, the writings of scholars and advocates on the autism spectrum, and personal, clinical and research experience we encourage our profession to take a leadership role in examining biases and changing the clinical and research landscape so that it better reflects respectful discourse for individuals on the autism spectrum. This is critical to reduce the stigma that continues to be associated with autism and has a negative affect on mental health and quality of life.

RESUMEN

Morality can help guide behavior and facilitate relationships. Although moral judgments by autistic people are similar to neurotypical individuals, many researchers argue that subtle differences signify deficits in autistic individuals. Moral foundation theory describes moral judgments in terms of differences rather than deficits. The current research, aimed at assessing autistic individuals' moral inclinations using Haidt's framework, was co-designed with autistic community members. Our aim was to describe autistic moral thinking from a strengths-based perspective while acknowledging differences that may pose interpersonal challenges among autistic youth. We assessed 25 autistic and 23 neurotypical children's moral judgments using the Moral Foundations Questionnaire for Kids. We used semi-structured interviews and qualitative analysis with a subset of participants to describe children's moral reasoning. Analyses suggested that autistic and neurotypical children make similar judgments about moral transgressions across all five moral foundations. General linear mixed modeling showed that the greatest predictor of recommending punishment was how bad children deemed moral transgressions to be. We also found a trend that autistic children were more likely to recommend punishment for harmless norms violations than were neurotypical children. Future research could use longitudinal methods to understand the development of moral judgments among autistic and neurotypical children.

RESUMEN

BACKGROUND: Sleep problems, particularly insomnia, are highly prevalent in children with neurodevelopmental disorders (NDD) and can negatively affect health and development. eHealth interventions may increase access to evidence-based care for insomnia for children with NDD, as programs are rare in most communities. Better Nights, Better Days (BNBD) is an online, parent-implemented intervention for pediatric insomnia in typically developing 1- to 10-year-olds. AIMS: The present study examined whether parents of children with NDD perceived the original BNBD to be usable, acceptable, and feasible, and what modifications might be necessary to adapt it for children with NDD. METHODS AND PROCEDURES: Twenty Canadian parents/caregivers of children aged 4-10 years with NDD and insomnia implemented the BNBD intervention with their children, and completed usability questionnaires. Questionnaire data were analyzed quantitatively (descriptive statistics) and qualitatively (thematic analysis). OUTCOMES AND RESULTS: Participants reported the intervention to be usable, useful, acceptable, and feasible. Several modifications were suggested to make the intervention more appropriate and acceptable for use with children with NDD. CONCLUSIONS AND IMPLICATIONS: Results support a largely transdiagnostic approach to treating sleep in children with NDD, and will inform the development of BNBD for Children with Neurodevelopmental Disorders (BNBD-NDD).

RESUMEN

Children today spend less time in nature than previous generations and there is concern that this shift negatively impacts children's cognitive abilities, particularly their ability to direct their attention. Theories, such as the Attention Restoration Theory (ART), suggest that contact with nature may replenish endogenous attention (e.g., directed, voluntary attention). There is a lack of rigorous research on how contact with nature is associated with attentional performance in children. This study employed a quasi-experimental design and included a sample of typically developing children to investigate performance on computerized endogenous and exogenous attention tasks before and after exposure to one of two interventions - a 30-min walk in either an urban (n = 30) or natural (forested, n = 30) environment. The two experimental groups were equivalent with regard to sex ratio, age, IQ, and connectedness to nature. Attention was assessed using the Combined Attention Systems Test (CAST), a state-of-the-art assessment tool designed to evaluate exogenous and endogenous attention characteristics. Bayesian hierarchical modeling of both response time (RT) and error rate (ER) was employed to evaluate the fixed effect of attentional measures and interactions with session and group. Consistent with predictions of ART, results support credible effects of the nature intervention on two measures of endogenous attention: Alerting RT: d = 0.85 (95% CI: 0.21-1.8), Orienting ER: d = 1.45 (95% CI: 0.17-7.18), but not on any of the measures of exogenous attention.

RESUMEN

Previous studies of emotion recognition suggest that detection of disgust relies on processing within the basal ganglia and insula. Research involving individuals with symptomatic and pre-diagnostic Huntington's disease (HD), a disease with known basal ganglia atrophy, has generally indicated a relative impairment in recognizing disgust. However, some data have suggested that recognition of other emotions (particularly fear and anger) may also be affected in HD, and a recent study found fear recognition deficits in the absence of other emotion-recognition impairments, including disgust. To further examine emotion recognition in HD, we administered a computerized facial emotion recognition task to 475 individuals with the HD CAG expansion and 57 individuals without. Logistic regression was used to examine associations of emotion recognition performance with estimated proximity to clinical diagnosis (based on CAG repeat length and current age) and striatal volumes. Recognition of anger, disgust, fear, sadness and surprise (but not happiness) was associated with estimated years to clinical diagnosis; performance was unrelated to striatal volumes. Compared to a CAG-normal control group, the CAG-expanded group demonstrated significantly less accurate recognition of all negative emotions (anger, disgust, fear, sadness). Additionally, participants with more pronounced motor signs of HD were significantly less accurate at recognizing negative emotions than were individuals with fewer motor signs. Findings indicate that recognition of all negative emotions declines early in the disease process, and poorer performance is associated with closer proximity to clinical diagnosis. In contrast to previous results, we found no evidence of relative impairments in recognizing disgust or fear, and no evidence to support a link between the striatum and disgust recognition.

RESUMEN

BACKGROUND: Despite the need for significant clinical intervention owing to the psychiatric manifestations of Huntington disease (HD), there has been a paucity of studies specifically designed to evaluate these symptoms prior to disease diagnosis. OBJECTIVES: To investigate whether the Symptom Checklist 90-Revised (SCL-90-R) and the Center for Epidemiological Studies Depression Scale can be used to detect psychiatric manifestations among preclinical mutation carriers with absent or minimal motor signs of HD. DESIGN, SETTING, AND PARTICIPANTS: Individuals at risk for or recently diagnosed with HD were recruited and then evaluated at Indiana University School of Medicine, Indianapolis. All of the subjects completed a uniform clinical evaluation that included the Unified Huntington's Disease Rating Scale-99, molecular testing to determine HD mutation status, the SCL-90-R, and the Center for Epidemiological Studies Depression Scale. The sample was divided into 4 study groups: 171 individuals in the nonmutation carrier group; 29 with minimal, if any, motor signs of HD in the preclinical mutation carrier group 1; 20 with motor abnormalities suggestive of HD in the preclinical mutation carrier group 2; and 34 in the manifest HD group. MAIN OUTCOME MEASURES: Scores on the SCL-90-R and Center for Epidemiological Studies Depression Scale were compared. RESULTS: Five SCL-90-R symptom dimensions (obsessive-compulsive, interpersonal sensitivity, anxiety, paranoid ideation, and psychoticism) demonstrated a significant group effect (P < or = .04). The preclinical mutation carrier group 2 and the manifest HD group scored significantly higher on all 5 dimensions as compared with the nonmutation carrier group. The preclinical mutation carrier group 2 scored significantly higher than the nonmutation carrier group for 3 of the SCL-90-R symptom dimensions (anxiety, paranoid ideation, and psychoticism). A significant group effect was found on the Center for Epidemiological Studies Depression Scale (P = .04). The frequency of depressive symptoms was significantly higher in the manifest HD group and the preclinical mutation carrier group 2 as compared with the nonmutation carrier group. CONCLUSION: This study identified specific psychiatric symptom dimensions that differentiate nonmutation carriers from individuals in the early preclinical stages of HD who are either symptom free or have minor nonspecific motor abnormalities.

RESUMEN

Previous studies of verbal episodic memory in pre-diagnostic Huntington's disease (HD) have yielded mixed results; some evidence suggests that memory decline is evident prior to the onset of pronounced neurological signs of HD, whereas other data indicate that memory function remains normal throughout the pre-diagnostic period. This study examines verbal episodic memory in a sample of CAG expanded individuals who have not yet been clinically diagnosed, and who represent a wide range of points along the continuum from health to disease. The Hopkins Verbal Learning Test-Revised (HVLT-R) was administered to 479 participants (428 with the HD CAG expansion and 51 without), and performance was compared to neurobiological indices of disease progression, including a DNA-based estimate of proximity to clinical diagnosis, magnetic resonance imaging (MRI) measures of striatal volume, and neurologist ratings of motor signs. Lower HVLT-R scores were associated with closer proximity to clinical diagnosis and smaller striatal volumes; these relationships were found even in groups with no neurological signs of HD. The CAG expanded groups, including those with only minimal neurological signs, had significantly lower HVLT-R scores than the control group, and performance was worse in sub-groups that had more neurological signs consistent with HD. These findings indicate that verbal episodic memory is affected in early pre-diagnostic HD and may decline as striatal volumes decrease and individuals approach the motor diagnostic threshold.

RESUMEN

OBJECTIVE: To characterize neurocognitive signs of disease progression in prediagnosis and early Huntington disease (HD) and compare the sensitivity of 2 disease staging classification schemes for detecting these signs. METHODS: Three hundred and six individuals at-risk for or recently diagnosed with HD completed the Unified Huntington's Disease Rating Scale, genetic testing, and a neurocognitive battery. Two schemes were used to estimate latency to onset of disease. One was based on genetic information (CAG repeat length) and the other was based on the extent of motor signs. Effect sizes were compared to assess the relative sensitivity of the 2 schemes for detecting signs of disease progression. RESULTS: CAG-expanded participants far from estimated diagnosis performed similarly to controls, whereas those near to estimated diagnosis were impaired relative to controls. Overall, the method employing genetic information yielded larger effect sizes than the motor scheme, particularly for strategic and executive function measures; the motor scheme resulted in a larger effect size for a measure of motor/psychomotor function. CONCLUSIONS: Neurocognitive function is not uniformly affected in prediagnosis and early HD; individuals near to their estimated age of diagnosis have cognitive signs similar to HD, whereas individuals far from estimated diagnosis appear cognitively normal. Classification schemes that incorporate both genetic and phenotypic information may be more sensitive for tracking neurocognitive signs of disease progression.

RESUMEN

Remote memory was assessed in persons with HIV-associated dementia (HIV-D), probable Alzheimer's disease (AD), and Huntington's disease (HD) and in healthy controls. The clinical groups were similar in overall dementia severity. Each clinical group exhibited impairments on remote memory tests relative to controls; however, temporally graded memory loss with selective preservation of older information was observed in the AD group but not the HD or HIV-D group. Analysis of cued retrieval indicated a preferential cuing benefit for the HIV-D and HD groups relative to the AD group. The similar pattern of remote memory performance demonstrated by the HIV-D and HD groups is a novel finding and suggests a subcortically mediated retrograde amnesia in HIV-D. The temporally graded pattern and the abnormal cued retrieval performance in the AD group are consistent with a consolidation deficit associated with extrahippocampal (cortical) and hippocampal damage.

RESUMEN

We tested the hypothesis that the direction of gaze of target faces may play a role in reported face recognition deficits in those with an autism spectrum disorder (ASD). In previous studies, typically developing children and adults better remembered faces in which the eyes were gazing directly at them compared with faces in which the eyes were averted. In the current study, high-functioning children and adolescents with an ASD and age- and IQ-matched typically developing controls were shown a series of pictures of faces in a study phase. These pictures were of individuals whose gaze was either directed straight ahead or whose gaze was averted to one side. We tested the memory for these study faces in a recognition task in which the faces were shown with their eyes closed. The typically developing group better remembered the direct-gaze faces, whereas the ASD participants did not show this effect. These results imply that there may be an important link between gaze direction and face recognition abilities in ASD.

RESUMEN

OBJECTIVES: Previous research suggests that children with autism spectrum disorders (ASD) are at a higher risk for painful experiences, but there is limited research examining pain in children with ASD. METHODS: The current study examined self-reported and parent-reported pain in 20 high-functioning youth with ASD (17 boys; 3 girls) and 20 typically developing controls (16 boys; 4 girls) ranging in age from 9 to 18 years and matched on age and IQ. Participants with and without ASD rated their hypothetical pain in a series of pictures depicting common childhood situations. They also rated the amount of pain they would expect to feel (using the Faces Pain Scale-Revised and a Numeric Rating Scale) in a series of validated hypothetical pain situations depicted in cartooned images (eg, scraping knee on sidewalk). Parents rated the amount of pain they would expect their child to show in each of the same cartoon stimuli. RESULTS: There were no significant differences between pain vignette ratings of youth with ASD and their non-ASD peers or in the ratings provided by their parents. High-functioning youth with ASD were able to successfully use both of the self-report scales to rate pain. DISCUSSION: This is the first study to successfully obtain self-report of pain from youth with ASD. Implications for the understanding of pain and pain assessment in high-functioning youth with ASD are discussed.

RESUMEN

According to the Task Support Hypothesis (TSH; Bowler et al. in Neuropsychologia 35:65-70, 1997) individuals with autism spectrum disorder (ASD) perform more similarly to their typically developing peers on learning and memory tasks when provided with external support at retrieval. We administered the California Verbal Learning Test-Children's Version to 15 high-functioning youths with ASD and 15 matched comparison participants. Although ASD and comparison participants had comparable levels of overall performance, the ASD group, but not the comparison group, improved significantly from free to cued recall, providing support for the TSH. These results indicate that verbal memory performance in youths with ASD is relatively intact, but may be facilitated by external supports.

RESUMEN

OBJECTIVE: PREDICT-HD is a large-scale international study of people with the Huntington disease (HD) CAG-repeat expansion who are not yet diagnosed with HD. The objective of this study was to determine the stage in the HD prodrome at which cognitive differences from CAG-normal controls can be reliably detected. METHOD: For each of 738 HD CAG-expanded participants, we computed estimated years to clinical diagnosis and probability of diagnosis in 5 years based on age and CAG-repeat expansion number (Langbehn, Brinkman, Falush, Paulsen, & Hayden, 2004). We then stratified the sample into groups: NEAR, estimated to be ≤9 years; MID, between 9 and 15 years; and FAR, ≥15 years. The control sample included 168 CAG-normal participants. Nineteen cognitive tasks were used to assess attention, working memory, psychomotor functions, episodic memory, language, recognition of facial emotion, sensory-perceptual functions, and executive functions. RESULTS: Compared with the controls, the NEAR group showed significantly poorer performance on nearly all of the cognitive tests and the MID group on about half of the cognitive tests (p = .05, Cohen's d NEAR as large as -1.17, MID as large as -0.61). One test even revealed significantly poorer performance in the FAR group (Cohen's d = -0.26). Individual tasks accounted for 0.2% to 9.7% of the variance in estimated proximity to diagnosis. Overall, the cognitive battery accounted for 34% of the variance; in comparison, the Unified Huntington's Disease Rating Scale motor score accounted for 11.7%. CONCLUSIONS: Neurocognitive tests are robust clinical indicators of the disease process prior to reaching criteria for motor diagnosis of HD.

RESUMEN

Estimates of premorbid intellect are often used in neuropsychological assessment to make inferences about cognitive decline. To optimize the method of controlling for premorbid intellect in assessments of prodromal neurodegenerative disease, we examined performance on the American National Adult Reading Test (ANART; administered during Years 1 and 3) and the two-subtest version of the Wechsler Abbreviated Scale of Intelligence (WASI; administered in Years 2 and 4) in an ongoing prospective longitudinal study of 371 participants with prodromal Huntington disease and 51 participants with normal CAG repeats. Although both measures performed similarly, the ANART demonstrated slightly lower variability in performance over a 2-year period and had slightly higher test-retest reliability than the WASI.

RESUMEN

Previous studies of global-local processing in autism spectrum disorders (ASDs) have indicated mixed findings, with some evidence of a local processing bias, or preference for detail-level information, and other results suggesting typical global advantage, or preference for the whole or gestalt. Findings resulting from this paradigm have been used to argue for or against a detail focused processing bias in ASDs, and thus have important theoretical implications. We applied Systems Factorial Technology, and the associated Double Factorial Paradigm (both defined in the text), to examine information processing characteristics during a divided attention global-local task in high-functioning individuals with an ASD and typically developing controls. Group data revealed global advantage for both groups, contrary to some current theories of ASDs. Information processing models applied to each participant revealed that task performance, although showing no differences at the group level, was supported by different cognitive mechanisms in ASD participants compared to controls. All control participants demonstrated inhibitory parallel processing and the majority demonstrated a minimum-time stopping rule. In contrast, ASD participants showed exhaustive parallel processing with mild facilitatory interactions between global and local information. Thus our results indicate fundamental differences in the stopping rules and channel dependencies in individuals with an ASD.

RESUMEN

Self-perception in high-functioning children and adolescents with Autism Spectrum Disorder (ASD) was examined by comparing parent- and self-reports on the Autism Spectrum, Empathy, and Systemizing Quotients (AQ, EQ and SQ). Participants were 20 youths with ASD and 22 typically developing controls. Both parents and participants in the ASD group reported more autistic traits (higher AQ) and less empathy (lower EQ) than the control group. SQ ratings did not differ between groups. Comparisons of self- and parent-reports indicated that youths with ASD reported significantly fewer autistic traits and more empathic features than their parents attributed to them. There were no discrepancies between parent- and self-reports in the control group. Implications regarding the use of self-report in ASD are discussed.
