[Effect of Plasmafiltration and Adsorption in Cocaine Abuse: A Case Report].

Rhabdomyolysis is one of the principal causes of acute kidney disease. Multiple endogenous and exogenous causes could start this process: cocaine addiction, a social phenomenon present in our Country among young adults, is one exogenous causes. Natural stimulating alkaloid cocaine has toxic action on multiple systems, principally central nervous system and cardiovascular system. Etiopathogenesis is related either to changes in local and systemic hemodynamics, or to direct damage caused by myofibril accumulation, or to immunological events leading to vasculitis or thrombotic microangiopathies. Scientific evidences describe different therapeutic approaches: supportive therapy, extracorporeal treatments and possible removal of the pathogenic noxa, and the therapeutic apheresis plays a role yet to be confirmed in this field. We describe the case of a 52-year-old man, hospitalized in the Cardiological Intensive Care Unit of our hospital, due to serious alterations in the indices of myocardiocytonecrosis and liver function, following cocaine abuse. During hospitalization, renal function indices worsened associated to diuresis contraction and onset of metabolic acidosis, not responsive to medical therapy. Also in consideration of myoglobin high circulating levels, related to rhabdomyolysis, the patient went under a cycle of selective apheresis using adsorption with a TR350 cartridge associated to hemodialysis: after two adsorption sessions, the patient resumed spontaneous diuresis with progressive normalization of the blood indices.

Autism and sexual and gender minority identity in college students: Examination of self-reported rates, functional outcomes, and treatment engagement.

LAY ABSTRACT: Autistic individuals and those who identify with a sexual and/or gender minority are both at risk for various mental health concerns and related impairments. However, the connection between autism and sexual and/or gender minorities and mental health and functional outcomes is not clear. Here, we provide evidence of these connections by analyzing data from a large nationally representative dataset from the American College Health Association-National College Health Assessment III. We found that autistic college students who identify with both sexual and gender minorities reported the highest rates of stress, academic, and mental health concerns including suicidality when compared with autistic college students with or without a sexual and/or gender minority. In addition, college students with at least two identities, such as autism and a sexual minority identity or both a sexual and gender minority identity, reported the next highest rates of concern. These findings affirm the need for mental healthcare providers to consider the intersections of a sexual and gender minority identities in non-autistic and, especially, in autistic college students to develop and provide better support and resources.

Triarchic traits as risk versus protective factors for ADHD symptomatology: A prospective longitudinal investigation.

Attention-deficit/hyperactivity disorder (ADHD) symptoms are associated with myriad adverse outcomes, including interpersonal difficulties, but factors that moderate the developmental course and functional impact of ADHD over time are not well understood. The present study evaluated developmental contributions of the triarchic neurobehavioral traits (boldness, meanness, and disinhibition) to ADHD symptomatology and its subdimensions from adolescence to young adulthood. Participants were twins and triplets assessed at ages 14, 17, and 19 (initial N = 1,185, 51.2% female). Path analyses using negative binomial regression revealed that boldness at age 14 was associated with more ADHD symptoms cross-sectionally (especially hyperactivity/impulsivity), but fewer symptoms (especially inattention) at age 19 in the prospective analysis. Notably, inclusion of interpersonal problems at ages 14 and 17 as covariates reduced the latter effect to nonsignificant. Disinhibition concurrently and prospectively predicted higher levels of ADHD symptoms, including both subdimensions, and the prospective effects were partially mediated by greater social impairment at age 17. Meanness prospectively (but not concurrently) predicted higher levels of hyperactivity/impulsivity symptoms. Sex moderated certain associations of meanness and disinhibition with ADHD symptoms. These findings highlight how fundamental neurobehavioral traits shape both psychopathology and adaptive outcomes in the developmental course of ADHD.

Working memory and math skills in children with and without ADHD.

OBJECTIVE: Children with attention-deficit/hyperactivity disorder (ADHD) frequently demonstrate deficits in working memory and in multiple domains of math skills, including underdeveloped problem-solving and computation skills. The Baddeley model of working memory posits a multicomponent system, including a domain-general central executive and two domain-specific subsystems-phonological short-term memory and visuospatial short-term memory. Extant literature indicates a strong link between neurocognitive deficits in working/short-term memory and math skills; however, the extent to which each component of working/short-term memory may account for this relation is unclear. METHOD: The present study was the first to use bifactor (S·I-1) modeling to examine relations between each working/short-term memory subcomponent (i.e., central executive, phonological short-term memory, and visuospatial short-term memory), ADHD symptoms, and math skills in a clinically evaluated sample of 186 children ages 8-13 (Myears = 10.40, SD = 1.49; 62 girls; 69% White/non-Hispanic). RESULTS: Structural equation modeling indicated that all three working/short-term memory components exert a significant and approximately equal effect on latent math skills (ß = .29-.50, all p < .05) and together explain 56% of the variance in children's math achievement (R² = .56). Exploratory analyses indicated that teacher-reported ADHD inattentive symptoms provided a small but significant contribution to predicting latent math skills (ΔR² = .07) and accounted for 24% of the central executive/math association. CONCLUSIONS: These findings suggest that math difficulties in children with ADHD and clinically evaluated children without ADHD are associated, in large part, with their neurocognitive vulnerabilities in working/short-term memory and, to a lesser extent, overt ADHD symptoms.

Evaluating the Simple View of Reading for Children With Attention-Deficit/Hyperactivity Disorder.

The 'simple view of reading' is an influential model of reading comprehension which asserts that children's reading comprehension performance can be explained entirely by their decoding and language comprehension skills. Children with ADHD often exhibit difficulty across all three of these reading domains on standardized achievement tests, yet it is unclear whether the simple view of reading is sufficient to explain reading comprehension performance for these children. The current study was the first to use multiple indicators and latent estimates to examine the veracity of key predictions from the simple view of reading in a clinically-evaluated sample of 250 children with and without ADHD (ages 8-13, Mage=10.29, SD=1.47; 93 girls; 70% White/Non-Hispanic). Results of the full-sample structural equation model revealed that decoding and language comprehension explained all (R2=.99) of the variance in reading comprehension for children with and without ADHD. Further, multigroup modeling (ADHD, Non-ADHD) indicated that there was no difference in the quantity of variance explained for children with ADHD versus clinically-evaluated children without ADHD, and that the quantity of explained variance did not differ from 100% for either group. Sensitivity analyses indicated that these effects were generally robust to control for monomethod bias, time sampling error, and IQ. These findings are consistent with 'simple view' predictions that decoding and language comprehension are both necessary and together sufficient for explaining children's reading comprehension skills. The findings extend prior work by indicating that the 'simple view' holds for both children with ADHD and clinically-evaluated children without ADHD.

[Chronic Inflammatory Polyradiculopathy Post-Covid-19 and the Role of Therapeutic Apheresis: A Clinical Case].

There is a strong correlation between SARS-CoV-2 and the onset of autoimmune neurological disease with atypical clinical presentation, characterized by limited response to medical therapy, likely caused by the underlying mechanism of the virus itself. In situations like these, after the failure of pharmacological therapy, therapeutic apheresis, including immunoadsorption, can be pursued. Treatments with IMMUSORBA TR-350 columns have proven to be particularly effective in managing refractory forms of post-Covid-19 nephropathies, leading to complete recovery of disability and elimination of neurological signs and symptoms. We discuss the case of a patient with chronic inflammatory polyradiculopathy post-Covid-19, resistant to medical therapy, effectively treated with immunoadsorption.

Assessing general versus specific liability for externalizing problems in adolescence: Concurrent and prospective prediction of symptoms of conduct disorder, ADHD, and substance use.

This study explored the generality versus specificity of two trait-liability factors for externalizing problems-disinhibition and callousness-in the concurrent and prospective prediction of symptoms of conduct disorder, attention-deficit/hyperactivity disorder (ADHD), and substance use (i.e., alcohol use disorder and history of illicit substance use). Disinhibition involves an impulsive, unrestrained cognitive-behavioral style; callousness entails a dispositional lack of social-emotional sensitivity. Participants were European adolescents from the multisite IMAGEN project who completed questionnaires and clinical interviews at ages 14 (N = 1,504, Mage = 14.41, 51.13% female) and 16 (N = 1,407, Mage = 16.46, 51.88% female). Disinhibition was related concurrently and prospectively to greater symptoms of conduct disorder, ADHD, and alcohol use disorder; higher scores on a general externalizing factor; and greater likelihood of having tried an illicit substance. Callousness was selectively related to greater conduct disorder symptoms. These findings indicate disinhibition confers broad liability for externalizing spectrum disorders, perhaps due to its affiliated deficits in executive function. In contrast, callousness appears to represent more specific liability for antagonistic (aggressive/exploitative) forms of externalizing, as exemplified by antisocial behavior. Results support the utility of developmental-ontogenetic and hierarchical-dimensional models of psychopathology and have important implications for early assessment of risk for externalizing problems.

Executive Functioning and Emotion Regulation in Children with and without ADHD.

Difficulties with emotion regulation affect the majority of youth with attention-deficit/hyperactivity disorder (ADHD) and predict greater functional impairment than ADHD symptoms alone. Deficits in executive functioning are also present for most children with ADHD, and have been linked with emotion regulation difficulties in both clinical and neurotypical populations throughout development. The current study was the first to assess all three core executive functions (working memory, inhibitory control, set shifting) simultaneously in a clinically-diverse sample of children with and without ADHD and common comorbidities and investigate the extent to which they uniquely predict emotion dysregulation. A sample of 151 children ages 8-13 years (M = 10.36, SD = 1.52; 52 girls; 70.2% White/Non-Hispanic) were assessed using a criterion battery of executive functioning tasks, teacher-reported ADHD symptoms, and parent-reported emotion regulation. Results of the bias-corrected, bootstrapped conditional effects path model revealed that better-developed working memory predicted better emotion regulation (ß = 0.23) and fewer ADHD symptoms (ß = -0.21 to -0.37), that ADHD symptoms (ß = -0.18 to -0.20) independently predicted emotion dysregulation, and that working memory exerted indirect effects on emotion regulation through both inattention and hyperactivity/impulsivity (ß = 0.04-0.07). Sensitivity analyses indicated that these effects were generally robust to control for age, sex, executive function interrelations, and inclusion/exclusion of children with co-occurring ASD. These findings underscore the importance of working memory (relative to inhibitory control and set shifting) and its relations with ADHD symptoms for understanding children's emotion regulation skills, and may help explain the limited efficacy of first-line ADHD treatments, which do not target working memory, for improving emotion regulation skills.

Executive functions and writing skills in children with and without ADHD.

OBJECTIVE: Pediatric attention-deficit/hyperactivity disorder (ADHD) has been associated with impairments in executive functioning and academic writing skills. However, our understanding of the extent to which these children's writing difficulties are related to their underdeveloped executive functions-and whether this relation is attributable to specific executive functions-is limited. METHOD: A clinically-evaluated and carefully-phenotyped sample of 91 children ages 8-13 (M = 10.60, SD = 1.25; 37 girls) were administered multiple, counterbalanced tests of the three core executive functions (working memory, inhibitory control, set shifting), assessed for ADHD symptoms via multiple-informant reports, and completed standardized, norm-referenced testing of three core writing skills (written expression, spelling, writing fluency). RESULTS: Bias-corrected, bootstrapped conditional effects modeling indicated that underdeveloped working memory exerted significant direct effects on all three writing skills, as well as indirect effects on written expression and spelling via the ADHD symptoms pathway (all 95% CIs exclude 0.0). In contrast, inhibitory control uniquely predicted spelling difficulties only, set shifting was not associated directly or indirectly with any assessed writing skill, and ADHD symptoms failed to uniquely predict writing skills after controlling for working memory. This pattern of results replicated across informants (parent vs. teacher ADHD symptom ratings), and was robust to control for age, sex, socioeconomic status (SES), majority/minority race/ethnicity status, intellectual functioning (IQ), decoding skills, language skills, and learning disability status. CONCLUSION: These findings suggest multiple pathways to writing skill difficulties in children with ADHD, while suggesting that their overt behavioral symptoms may be less involved in their writing difficulties than their underlying neurocognitive vulnerabilities.

Activities of daily living and working memory in pediatric attention-deficit/hyperactivity disorder (ADHD).

Most children with ADHD have impaired working memory abilities. These working memory deficits predict impairments in activities of daily living (ADLs) for adults with ADHD. However, our understanding of the relation between pediatric ADHD and ADLs is limited. Thus, this study aimed to examine (1) the extent to which pediatric ADHD is associated with ADL difficulties; and if so (2) the extent to which these difficulties are related to their well-documented working memory difficulties and/or core ADHD inattentive and hyperactive/impulsive symptom domains. A well-characterized, clinically evaluated sample of 141 children ages 8-13 years (M = 10.36, SD = 1.46; 51 girls; 70% White/non-Hispanic) were administered a battery of well-validated working memory tests and assessed for ADHD symptoms (teacher-ratings) and ADL difficulties (parent-ratings); cross-informant reports were used to control for mono-informant bias. Children with ADHD exhibited medium magnitude difficulties with ADLs (d = 0.61, p < .005, 38% impaired). Results of the bias-corrected, bootstrapped conditional effects model indicated that lower working memory predicted reduced performance of age-expected ADLs (ß =0.28) and greater ADHD inattentive (ß = -0.40) and hyperactive/impulsive symptoms (ß = -0.16). Greater inattentive, but not hyperactive/impulsive, symptoms predicted greater ADL difficulties (ß = -0.36) even after controlling for working memory. Interestingly, working memory exerted a significant indirect effect on ADLs via inattentive (indirect effect: ß = 0.15, effect ratio = .54) but not hyperactive/impulsive symptoms. These findings implicate ADHD inattentive symptoms as a potential mechanism underlying ADL difficulties for children with ADHD, both independently and via working memory's role in regulating attention.
