Background: Wider availability of cannabis through medical and recreational legalization (MCL alone and RCL+MCL) has been hypothesized to contribute to reductions in opioid use, misuse, and related harms. We examined whether state adoption of cannabis laws was associated with changes in opioid outcomes overall and stratified by cannabis use.

Methods: Using National Survey on Drug Use and Health (NSDUH) data from 2015 to 2019, we estimated cannabis law associations with opioid (prescription opioid misuse and/or heroin use) misuse and use disorder.

Malignant peripheral nerve sheath tumors (MPNSTs) are aggressive sarcomas and the primary cause of mortality in patients with neurofibromatosis type 1 (NF1). These malignancies develop within preexisting benign lesions called plexiform neurofibromas (PNs). PNs are solely driven by biallelic loss eliciting RAS pathway activation, and they respond favorably to MEK inhibitor therapy.

Unlabelled: One of the most critical intervention strategies when working with individuals with significant language delays associated with autism spectrum disorder and related developmental delays is teaching mands. For mand training to be effective, an establishing operation (EO) must be in effect, yet EOs are often difficult to observe. Before learning to mand, an individual may point to or approach a reinforcer, which likely indicates an EO related to that reinforcer, and may be considered an indicating response (IR).

Human endocrine cell differentiation and islet morphogenesis play critical roles in determining islet cell mass and function, but the events and timeline of these processes are incompletely defined. To better understand early human islet cell development and maturation, we collected 115 pediatric pancreata and mapped morphological and spatiotemporal changes from birth through the first ten years of life. Using quantitative analyses and a combination of complementary tissue imaging approaches, including confocal microscopy and whole-slide imaging, we developed an integrated model for endocrine cell formation and islet architecture, including endocrine cell type heterogeneity and abundance, endocrine cell proliferation, and islet vascularization and innervation.

The MEK inhibitor selumetinib induces objective responses and provides clinical benefit in children with neurofibromatosis type 1 (NF1) and inoperable plexiform neurofibromas (PNs). To evaluate whether similar outcomes were possible in adult patients, in whom PN growth is generally slower than in pediatric patients, we conducted an open-label phase 2 study of selumetinib in adults with NF1 PNs. The study was designed to evaluate objective response rate (primary objective), tumor volumetric responses, patient-reported outcomes and pharmacodynamic effects in PN biopsies.

Background: As air travel and immobility are risk factors for venous thromboembolism, we aimed to test the hypothesis that internationally transferred trauma patients have a high incidence of venous thromboembolism on arrival.

Methods: A prospectively maintained registry of all international transferred trauma patients who presented to our level I trauma center from January 2023 to June 2024 was retrospectively reviewed. Patients with either lower extremity venous duplex ultrasound or computed tomography scan of the chest with contrast on arrival were included.

Metabolically active cells emit volatile organic compounds (VOCs) that can be used in real time to non-invasively monitor the health of cell cultures. We utilized these naturally occurring VOCs in an adapted culture method to detect differences in culturing Chinese hamster ovary (CHO) cells with and without Staphylococcus epidermidis and Aspergillus fumigatus contaminations. The VOC emissions from the cell cultures were extracted and measured from the culture flask headspace using polydimethylsiloxane (PDMS)-coated Twisters, which were subjected to thermal desorption-gas chromatography-mass spectrometry (TD-GC-MS) analysis.

Pyrrolizidine alkaloid N-oxides (PA-N-oxides) are predominant in plants and herbal foods, and are converted to pyrrolizidine alkaloids (PAs) upon consumption, leading to toxicity. The effect of interindividual kinetic differences on the relative potency values of PA-N-oxides compared to their PAs (REP) was studied, with riddelliine N-oxide (RIDO) and riddelliine (RID) as model compounds. In vitro kinetic data measured in incubations with 30 fecal and 25 liver S9 donor samples showed high variation across individuals, where the interindividual variability was captured with Bayesian multilevel regression.

Peyronie's disease (PD) is an underdiagnosed and undertreated fibroproliferative disorder associated with the formation of plaques that results in penile curvature and discourages some men from seeking medical consultation. The PD self-assessment app, a digital application (app), was developed to increase PD awareness, provide men with a self-screening and educational tool for PD, and help eliminate barriers to seeking consultation with a physician. Prior to deployment, 4 board-certified urologists provided qualitative reviews on the app's usability and utility as a screening tool.

Harm reduction programs provide tools that enable people who use drugs to do so more safely in a nonstigmatizing environment without the goal of them necessarily seeking treatment or abstinence. Most harm reduction programs in the United States distribute sterile syringes and naloxone and safely dispose of used syringes and other drug use supplies. Many also provide drug checking services, and other safer use supplies.

Objectives: In response to the escalating overdose crisis there is an urgent need for innovative strategies to reduce overdose death. Emergency Medical Services (EMS) is uniquely poised to reduce mortality and other harms associated with opioid use through prevention, harm reduction, and treatment, yet there is a paucity of nationally recognized best practices or quality measures to guide prehospital quality improvement (QI) efforts related to opioid use disorder (OUD).

Methods: A multidisciplinary team of subject matter experts in addiction medicine, EMS, public health, and QI was convened to develop recommendations for a model QI framework for prehospital OUD prevention, harm reduction, and treatment based on the Model for Improvement framework.

Objective: In the United States, ursodiol is commercially available as solid dosage forms, which represents a problem for children who cannot swallow capsules or tablets. There is a lack of an age-appropriate formulation for ursodiol, and the extemporaneous preparation of an oral suspension with an extended beyond-use-date (BUD) may represent a good therapeutic alternative for the pediatric population. However, all pharmacists need validated stability studies to prepare oral liquids with high quality and safety.

Hematopoietic progenitor kinase 1 (HPK1/MAP4K1) represents a high interest target for the treatment of cancer through an immune-mediated mechanism. Herein we present highlights of the drug discovery campaign within the lactam/azalactam series of inhibitors that yielded a small molecule (, PF-07265028), which was advanced to a phase 1 clinical trial (NCT05233436). Key components of the discovery effort included optimization of potency through mitigation of ligand strain as guided by the use of cocrystal structures, mitigation of ADME liabilities (plasma instability and fraction metabolism by CYP2D6), and optimization of kinase selectivity, particularly over immune-modulating kinases with high homology to HPK1.
