Background: The association between skeletal muscle and adipose tissue (body composition) and early response using positron emission tomography (PET) in pediatric Hodgkin lymphoma (HL) remains unstudied.

Methods: Patients enrolled on Children's Oncology Group studies AHOD0031 (intermediate-risk HL) and AHOD0831 (high-risk HL) with digital abdominal computed tomography (CT) scans at diagnosis and PET scans after 2 cycles (PET2) were included. Two consecutive slices at the third lumbar vertebra were identified and skeletal muscle index (SMI, in cm2/m2) and total adipose tissue index (TATI, in cm2/m2) were calculated using sliceOmatic (Magog, Canada) and height at diagnosis.

Background: Recovery management checkups done in primary care settings (RMC-PCs) can be an effective intervention to link individuals with substance use disorders (SUD) to treatment and help them stay engaged with treatment. There is reason to question, however, whether RMC-PCs are as effective for those who have been recently incarcerated or for those holding a minoritized, racial identity.

Methods: We examined data from a randomized controlled trial of RMC-PCs compared to a control condition ( = 266).

Approximately 20%-40% of individuals with Tourette syndrome (TS) have rage attacks (RAs), which are recurrent, explosive behavioral outbursts that can cause significant functional impairment. Despite the impact of RA in TS, there has been limited research on treatment, and most studies have focused on pharmacologic interventions. Nonpharmacologic interventions have the potential to improve symptoms with fewer side effects.

Background: Hypereosinophilic syndromes (HES) are a heterogenous group of eosinophilic disorders. To date, only retrospective studies of limited sample-size and/or follow-up duration are available.

Methods: The COHESion study is a national prospective multicenter multidisciplinary cohort recruiting both adults or children with the spectrum of eosinophilic disorders (including reactive HE/HES [HE/HES-R], idiopathic HES [HES-I], lymphocytic HES [HES-L], neoplastic HE/HES [HE/HES-N], HE of unknown significance [HE-US], as well as IgG4-related disease [IgG4RD] or ANCA-negative eosinophilic granulomatosis with polyangiitis [EGPA] overlaps).
