Parent-led cognitive behavioral therapy (CBT) is an efficient, promising form of therapy that may be well suited for autistic youth with anxiety disorders. A recent clinical trial found that parent-led CBT - in which parents led their child through a guided CBT workbook with varying degrees of therapist support - was efficacious for reducing anxiety and associated functional impairment. While such findings demonstrate promise for future intervention development and dissemination efforts with this population, more work is needed to elucidate clinical factors that impact response to treatment as well as drop-out.

Background: The body composition of National Collegiate Athletic Association (NCAA) athletes is well documented but no such data exist for university club sports athletes. Additionally, the majority of norms for NCAA athletes were created from individual methods requiring assumptions.

Objective: This study used a four-component (4C) model to measure the body composition of university club sports athletes.

Background: During the COVID-19 pandemic, virtual care was used to deliver primary care services. Nurses contributed to primary care teams' capacity to deliver care virtually. This study explored nurses' roles in virtual care delivery in primary care and the barriers and facilitators that influenced their contributions.

Owing to their rapid cooling rate and hence loss-limited propagation distance, cosmic-ray electrons and positrons (CRe) at very high energies probe local cosmic-ray accelerators and provide constraints on exotic production mechanisms such as annihilation of dark matter particles. We present a high-statistics measurement of the spectrum of CRe candidate events from 0.3 to 40 TeV with the High Energy Stereoscopic System, covering 2 orders of magnitude in energy and reaching a proton rejection power of better than 10^{4}.

While rising global rates of neurodegenerative disease encourage early diagnosis and therapeutic intervention to block clinical expression (secondary prevention), a more powerful approach is to identify and remove environmental factors that trigger long-latencybrain disease (primary prevention) by acting on a susceptible genotype or acting alone. The latter is illustrated by the post-World War II decline and disappearance of Amyotrophic Lateral Sclerosis and Parkinsonism-Dementia Complex (ALS/PDC), a prototypical often-familial neurodegenerative disease formerly present in very high incidence on the island of Guam. Lessons learned from 75 years of investigation on the etiology of ALS/PDC include: the importance of focusing field research on the disease epicenter and patients with early-onset disease; soliciting exposure history from patients, family, and community to guide multidisciplinary biomedical investigation; recognition that disease phenotype may vary with exposure history, and that familial brain disease may have a primarily environmental origin.
