BACKGROUND: Elevated depression symptoms have been associated with higher insulin resistance in adolescents, and consequently, greater risk for type 2 diabetes (T2D). Mindfulness-based intervention (MBI) may be suited for adolescents at risk for T2D given its potential to decrease depression and improve stress-related behavior/physiology underpinning insulin resistance. To prepare for a future multisite efficacy randomized controlled trial, a rigorous, multisite, pilot and feasibility study is needed to test this approach...

Polycystic ovary syndrome (PCOS) is a lifelong chronic condition that affects one in ten females and can be diagnosed in adolescence. As adolescents with PCOS transition to adulthood, counselling for lifestyle management and mental health concerns often transition from involving the family unit to increasingly individual-focused approaches. PCOS is associated with a large range of comorbidities affecting reproductive, metabolic, dermatological, and psychological health. The diagnosis and comorbidities of PCOS are influenced by pubertal hormones and need to be reassessed continuously to ensure that treatment remains appropriate for age and development...

INTRODUCTION: Adolescence involves significant reorganization within the medial prefrontal cortex (mPFC), including modifications to inhibitory neurotransmission that may be mediated through parvalbumin (PV) interneurons and their surrounding perineuronal nets (PNNs). These developmental changes, which can result in increased PV neuron activity in adulthood, may be disrupted by drug use resulting in lasting changes in mPFC function and behavior. Methamphetamine (METH), which is a readily available drug used by some adolescents, increases PV neuron activity and could influence the activity-dependent maturational process of these neurons...

INTRODUCTION: Recovery support services (RSS), while not yet precisely defined, nevertheless have a longstanding role in managing chronic illnesses including substance use disorders (SUDs). This exploratory study is the first to identify the amounts of money that states invest from Substance Abuse and Mental Health Services Administration (SAMHSA) Block Grants; SAMHSA discretionary grant and state-appropriated sources; the types of organizations from which RSS are purchased; and the non-financial supports states provide for RSS...

BACKGROUND: Bintrafusp alfa, a first-in-class bifunctional fusion protein targeting transforming growth factor-β (TGF-β) and programmed cell death ligand 1, has demonstrated encouraging efficacy as second-line treatment in patients with non-small cell lung cancer (NSCLC) in a dose expansion cohort of the phase 1, open-label clinical trial (NCT02517398). Here, we report the safety, efficacy, and biomarker analysis of bintrafusp alfa in a second expansion cohort of the same trial (biomarker cohort)...

Use of amphetamines during adolescence, a critical period of brain development and reorganization, may lead to particularly adverse outcomes that are long-lasting. Similarly, female users may be uniquely vulnerable to certain aspects of drug use. A recognition of the role of use during adolescence and sex on outcomes of amphetamine and methamphetamine exposure are of critical importance in understanding and treating substance use disorders. This chapter highlights what human research, which has been largely epidemiological, suggests about sex and age differences in drug use patterns and outcomes...

OBJECTIVE: Among adolescents, disinhibited eating and anxiety commonly co-occur. Precision intervention approaches targeting unique mechanistic vulnerabilities that contribute to disinhibited eating and anxiety may therefore be helpful. However, the effectiveness of such interventions hinges on knowledge of between- and within-person associations related to disinhibited eating, anxiety, and related processes. METHOD: A sample of 39 adolescent females (12-17 years) with elevated anxiety and above-average weight (BMI %ile ≥ 75th) completed measures of theoretically driven social and cognitive-behavioral variables, disinhibited eating, and anxiety via ecological momentary assessment over 7 days...

BACKGROUND: We described participant demographics for National Cancer Institute (NCI) clinical trials at the Clinical Center (CC) of the National Institutes of Health (NIH) (NCI-CC participants) to identify enrollment disparities. METHODS: We analyzed NCI-CC data from 2005-2020, calculated enrollment fractions (EF), compared with the U.S. cancer population represented by the Surveillance, Epidemiology, and End Results (SEER) cancer incidence data (2018) and the Cancer in North American (CiNA) database (2018), and with clinical trial disparities data from NCI's Community Oncology Research Program (NCORP) and National Clinical Trials Network (NCTN) (2005-2019), and from ClinicalTrials...

BACKGROUND: The capability of large language models (LLMs) to understand and generate human-readable text has prompted the investigation of their potential as educational and management tools for patients with cancer and healthcare providers. MATERIALS AND METHODS: We conducted a cross-sectional study aimed at evaluating the ability of ChatGPT-4, ChatGPT-3.5, and Google Bard to answer questions related to 4 domains of immuno-oncology (Mechanisms, Indications, Toxicities, and Prognosis)...

RATIONALE AND OBJECTIVES: Efficiently detecting and characterizing metastatic bone lesions on staging CT is crucial for prostate cancer (PCa) care. However, it demands significant expert time and additional imaging such as PET/CT. We aimed to develop an ensemble of two automated deep learning AI models for 1) bone lesion detection and segmentation and 2) benign vs. metastatic lesion classification on staging CTs and to compare its performance with radiologists. MATERIALS AND METHODS: This retrospective study developed two AI models using 297 staging CT scans (81 metastatic) with 4601 benign and 1911 metastatic lesions in PCa patients...

OBJECTIVE: Interpersonal psychotherapy (IPT) has been proposed for prevention of excess weight gain among adolescents with loss-of-control (LOC) eating. Mixed findings from a trial testing this conjecture warrant elucidation of potential outcome predictors. The therapeutic alliance (adolescent-facilitator emotional bond and task collaboration) may be important for IPT but has received little attention in weight-related interventions. This study evaluated associations of adolescent-reported therapeutic alliance during IPT with weight- and eating-related outcomes...

We report single-shot, time-resolved observation of self-steepening and temporal splitting of near-infrared, 50 fs, micro-joule pulses propagating nonlinearly in flint (SF11) glass. A coherent, smooth-profiled, 60-nm-bandwidth probe pulse that propagated obliquely to the main pulse through the Kerr medium recorded a time sequence of longitudinal projections of the main pulse's induced refractive index profile in the form of a phase-shift "streak," in which frequency-domain interferometry recovered with ∼10 fs temporal resolution...

Despite the success of programmed cell death-1 (PD-1) and PD-1 ligand (PD-L1) inhibitors in treating solid tumors, only a proportion of patients respond. Here, we describe a first-in-class bifunctional therapeutic molecule, STAR0602, that comprises an antibody targeting germline Vβ6 and Vβ10 T cell receptors (TCRs) fused to human interleukin-2 (IL-2) and simultaneously engages a nonclonal mode of TCR activation with costimulation to promote activation and expansion of αβ T cell subsets expressing distinct variable β (Vβ) TCR chains...

Older adults with type II diabetes (T2D) are at risk of developing nerve disorders that result in functional impairment. Most work in proprioceptive dysfunction in older adults with T2D has focused on functional deficits of the lower limb. The purpose of this study was to examine proprioceptive effects of T2D on the upper limb in older adults. Kinematic performance of a reach-to-pinch action toward a virtual target was assessed in a T2D group (60+ years old with T2D) and a healthy age- and sex-matched control group...

PURPOSE: Chimeric antigen receptor (CAR) and T-cell receptor (TCR) T-cell therapies are effective in a subset of patients with solid tumors, but new approaches are needed to universally improve patient outcomes. Here, we developed a technology to leverage the cooperative effects of IL-15 and IL-21, two common cytokine-receptor gamma chain family members with distinct, pleiotropic effects on T-cells and other lymphocytes, to enhance the efficacy of adoptive T-cells. EXPERIMENTAL DESIGN: We designed vectors that induce the constitutive expression of either membrane-tethered IL-15, IL-21, or IL-15/IL-21...

Recurrent respiratory papillomatosis (RRP) is a rare, debilitating neoplastic disorder caused by chronic infection with human papillomavirus (HPV) type 6 or 11 and characterized by growth of papillomas in the upper aerodigestive tract. There is no approved medical therapy, and patients require repeated debulking procedures to maintain voice and airway function. PRGN-2012 is a gorilla adenovirus immune-therapeutic capable of enhancing HPV 6/11-specific T cell immunity. This first-in-human, phase 1 study (NCT04724980) of adjuvant PRGN-2012 treatment in adult patients with severe, aggressive RRP demonstrates the overall safety and clinically meaningful benefit observed with PRGN-2012, with a 50% complete response rate in patients treated at the highest dose...

Significant exposure to alcohol or cannabis during adolescence can induce lasting disruptions of neuronal signaling in brain regions that are later to mature, such as the medial prefrontal cortex (mPFC). Considerably less is known about the effects of alcohol and cannabis co-use, despite its common occurrence. Here, we used male and female Long-Evans rats to investigate the effects of early-life exposure to ethanol, delta-9-tetrahydrocannabinol (THC), or their combination on high frequency stimulation (HFS)-induced plasticity in the prelimbic region of the mPFC...

BACKGROUND: The emergence of positron emission tomography (PET) in prostate cancer is impacting clinical practice, but little is known about PET imaging as a tool to determine treatment failure in metastatic castration-resistant prostate cancer (mCRPC). OBJECTIVE: To evaluate PET imaging dynamics in mCRPC patients on enzalutamide with stable computed tomography (CT) and technetium-99m (Tc99) bone scans. DESIGN, SETTING, AND PARTICIPANTS: All patients were on treatment with enzalutamide for first-line mCRPC in a clinical trial at the National Cancer Institute (Bethesda, MD, USA)...
