Next-generation vaccines are essential to address the evolving nature of SARS-CoV-2 and to protect against emerging pandemic threats from other coronaviruses. These vaccines should elicit broad protection, provide long-lasting immunity and ensure equitable access for all populations. In this study, we developed a panel of chimeric, full-length spike antigens incorporating mutations from previous, circulating and predicted SARS-CoV-2 variants.

School climate represents a potentially critical but understudied influence on sleep difficulties, given growing evidence supporting its association with health outcomes. The present study is the first to utilize a multimethod, multi-informant approach, including adolescent-report, parent-report, and actigraphy, to examine associations between school climate and different aspects of sleep functioning among adolescents with and without attention-deficit/hyperactivity disorder.

Mobile health interventions offer a promising approach to providing education and psychosocial support, yet their effectiveness in this context remains underexplored.
Objective: This study aimed to develop and evaluate the effectiveness of an innovative, mobile-based, perioperative care program for women undergoing breast cancer surgery (iCareBreast).
Background: The study of ADHD has predominantly focused on individual-level risk-factors, and less is known about contextual factors that promote adaptive functioning.
Aims: The present study is the first to evaluate the longitudinal association between five dimensions of school climate (academic expectations, student engagement, disciplinary structure, respect for students, willingness to seek help) and student outcomes, and whether ADHD symptom severity moderates those associations.
Methods And Procedures: Participants included 274 adolescents (45 % female) who completed assessments in 8th (T1) and 10th (T2) grades.
Purpose: The present study adds to the literature by evaluating the differential risk of ADHD symptom dimensions and executive functioning (EF; time management, organization, motivation) to key occupational outcomes.
Methods: Participants were adults (N = 100; 51% male) with ADHD working full-time between the ages of 19-30 (M = 26.61, SD = 2.
Background: Guidelines recommend annual anal cytology-based squamous cell carcinoma of anus (SCCA) screening for men who have sex with men with HIV aged ≥35 years (eligible population). The recommended threshold for high-resolution anoscopy (HRA) depends on its availability: low-threshold (any abnormal cytology) if availability is high and high-threshold (high-grade squamous intraepithelial lesion [HSIL] on cytology) if availability is low.
Methods: This was a retrospective chart review (2018-2022) at academic HIV clinics.
Objective: Children with attention-deficit/hyperactivity disorder (ADHD) exhibit difficulties with organizational skills such as task planning, managing materials, and organizing activities that have downstream consequences on academic functioning. At the same time, deficits in working memory have been linked with both the organizational skills difficulties and academic underachievement and underperformance observed in children with ADHD and have been hypothesized to account for the link between organizational and academic functioning. However, the extent to which working memory and organizational skills independently versus jointly contribute to ADHD-related academic difficulties remains unclear.

However, it remains unclear whether this pattern reflects a large number of distinct deficits or a small number of deficit(s) that broadly impact test performance. The current study is among the first experiments to systematically manipulate demands on both working memory and inhibition, with implications for competing conceptual models of ADHD pathogenesis.
View Article and Find Full Text PDFAttention-deficit/hyperactivity disorder (ADHD) has primarily been studied from a deficit-focused perspective. However, there are individuals with ADHD who exhibit resilience or a pattern of positive adaptation despite the risks associated with their diagnosis. The present study evaluated whether peer acceptance predicted resilience for adolescents with ADHD and if self-efficacy or a stress-is-enhancing mindset served as mechanisms of those relations.
View Article and Find Full Text PDFWe evaluated the sensitivity of estimated PM and NO health impacts to varying key input parameters and assumptions including: 1) the spatial scale at which impacts are estimated, 2) using either a single concentration-response function (CRF) or using racial/ethnic group specific CRFs from the same epidemiologic study, 3) assigning exposure to residents based on home, instead of home and work locations for the state of Colorado. We found that the spatial scale of the analysis influences the magnitude of NO, but not PM, attributable deaths. Using county-level predictions instead of 1 km predictions of NO resulted in a lower estimate of mortality attributable to NO by ∼ 50 % for all of Colorado for each year between 2000 and 2020.

Ample evidence suggests that one method used by some members of stigmatized groups to manage the stigma they face-concealing their stigmatized identities-may contribute to these health and wellbeing disparities. However, precisely why concealment may contribute to these disparities is less clear.

Epidemiologic studies have consistently observed associations between fine particulate matter (PM) exposure and premature mortality. These studies use air quality concentration information from a combination of sources to estimate pollutant exposures and then assess how mortality varies as a result of differing exposures. Health impact assessments then typically use a single log-linear hazard ratio (HR) per health outcome to estimate counts of avoided human health effects resulting from air quality improvements.

Growing evidence suggests that childhood ADHD is associated with larger impairments in working memory relative to inhibition. However, most studies have not considered the role of co-occurring anxiety on these estimates - a potentially significant confound given prior evidence that anxiety may increase working memory difficulties but decrease inhibition difficulties for these children. The current study extends prior work to examine the extent to which co-occurring anxiety may be systematically affecting recent estimates of the magnitude of working memory/inhibitory control deficits in ADHD.
View Article and Find Full Text PDFObjective: 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.

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, M=10.

These approaches reduce computation time by making simplifying assumptions about pollutant source characteristics, transport and chemistry. Two reduced form tools used by the Environmental Protection Agency in recent assessments are source apportionment-based benefit per ton (SA BPT) and source apportionment-based air quality surfaces (SABAQS).

Aims: The current study sought to provide a preliminary 'shortlist' of key individual, family, and social-community assets among children with ADHD.
Methods And Procedures: The study included well-characterized, clinically-evaluated samples of children with (n=108) and without ADHD (n=98) ages 8-13 years (M=10.
Objective: The current randomized controlled trial (RCT) was the first to examine the benefits of central executive training (CET, which trains the components of working memory [WM]) for reducing organizational skills difficulties relative to a carefully matched neurocognitive training intervention (inhibitory control training [ICT]).
Method: A carefully phenotyped sample of 73 children with attention-deficit/hyperactivity-impulsivity disorder (ADHD; ages 8-13, = 10.15, = 1.
Objective: Our objective was to characterize the incidence, associated clinical factors, timing of infection, microbiology, and incidence of concordant blood culture of urinary tract infections (UTIs) in very low birth weight (VLBW <1,500g) infants.
Study Design: Multicenter observational cohort study of VLBW infants with gestational age (GA) ≤32 weeks, still hospitalized on postnatal day 7, and discharged 2010 to 2018 from Pediatrix Medical Group neonatal intensive care units. Demographic and clinical characteristics of infants with and without UTI were compared.
Circadian clock and chromatin-remodeling complexes are tightly intertwined systems that regulate rhythmic gene expression. The circadian clock promotes rhythmic expression, timely recruitment, and/or activation of chromatin remodelers, while chromatin remodelers regulate accessibility of clock transcription factors to the DNA to influence expression of clock genes. We previously reported that the BRAHMA (BRM) chromatin-remodeling complex promotes the repression of circadian gene expression in Drosophila.

Working memory and inhibitory control represent promising intervention targets given their functional, if not causal, links with ADHD-related emotion dysregulation.
Methods: This preregistered randomized controlled trial tested whether two digital therapeutic training protocols that have been previously shown to improve working memory (Central Executive Training [CET]) and inhibitory control (Inhibitory Control Training [ICT]) can improve emotion regulation in a sample of 94 children with ADHD aged 8-13 years ( = 10.

Introduction: Stent under-expansion due to calcification is associated with a less durable result. The development of intravascular lithotripsy (IVL) has provided clinicians with a readily available, simple-to-use treatment option for coronary calcification, but the use of IVL within a previously stented segment is currently off-license. There are, however, developing data suggesting that the use of IVL can be an effective treatment option for patients with calcific stent under-expansion.

Here, we report the identification of netrin-1 as an endogenous allosteric modulator of GABARs. Following increased neuronal excitability, netrin-1 is secreted and binds to the extracellular domains of GABAR subunits, thereby inducing homeostatic upscaling of GABAR-mediated synaptic efficacy and currents.
