Introduction: Down Syndrome Regression Disorder (DSRD) is a neuropsychiatric condition causing insomnia, catatonia, encephalopathy, and obsessive-compulsive behavior in otherwise healthy individuals with Down syndrome (DS). Smaller cohorts have identified heterogenous diagnostic abnormalities which have predicted immunotherapy responsiveness although pattern analysis in a large cohort has never been performed.
Methods: A multi-center, retrospective study of individuals with DSRD was performed.

Stable isotopes of carbon (δC) and nitrogen (δN) are commonly employed to reconstruct past change in marine ecosystems and nutrient cycling. However, multiple biogeochemical and physical drivers govern spatiotemporal variability of these isotopic signals, particularly in dynamic coastal systems, complicating interpretation. Here, we coupled a modern multi-year (2010-2019) δC and δN isoscape record from intertidal mussels (Mytilus californianus) with high-resolution ocean model output and satellite chlorophyll-a observations in the California Current System (32°-43° N) to identify major drivers of isotopic variability.

Background: Trauma and pregnancy are both risk factors for venous thromboembolism (VTE). We hypothesized that pregnant blunt trauma patients would have a higher incidence of VTE complications compared with matched nonpregnant females.
Methods: We conducted a retrospective cohort study using National Trauma Data Bank data from 2017 to 2022.

The MINDSPACE framework has made it easier to incorporate insights from behavioral science into policy, including health policy, but lacks granularity. Difficult policy problems such as adherence to psychiatric medication can benefit from judicious selection of nudges. We present a MINDSPACE Expanded Framework including 34 insights from behavioral science in the 9 MINDSPACE principles to support a more detailed integration of behavioral science into policy.

Trends in diagnostic biopsy sample collection approaches for primary bone sarcomas have shifted in the past 2 decades. Although open/incisional biopsies used to be the predominant approach to obtain diagnostic material for Ewing sarcoma and osteosarcoma, image-guided core needle biopsies have increased in frequency and are safe for patients. These procedures are less invasive and reduce recovery times but have potential limitations.

Background: Tramadol is an adulterant of illicit opioids. As it is a serotonin-norepinephrine reuptake inhibitor as well as a μ-opioid agonist, tramadol adulteration may worsen overdose signs and symptoms or affect the amount of naloxone patients receive.
Methods: This is a multicenter, prospective cohort of adult patients with suspected opioid overdoses who presented to one of eight United States emergency departments and were included in the Toxicology Investigators Consortium's Fentalog Study.

Background: Adults living with head and neck burn injuries experience psychosocial consequences due to scarring as well as functional disabilities. However, the impact of head and neck burns on long-term self-reported psychosocial outcomes, return to work, and need for reconstructive surgery has not been well described. This study investigates the unique longitudinal problems in psychosocial and functional recovery faced by adults with head and neck burn injuries.

The development of photoswitches that absorb low energy light is of notable interest due to the growing demand for smart materials and therapeutics necessitating benign stimuli. Donor-acceptor Stenhouse adducts (DASAs) are molecular photoswitches that respond to light in the visible to near-infrared spectrum. As a result of their modular assembly, DASAs can be modified at the donor, acceptor, triene, and backbone heteroatom molecular compartments for the tuning of optical and photoswitching properties.

Conventional artificial intelligence (AI) systems are facing bottlenecks due to the fundamental mismatches between AI models, which rely on parallel, in-memory, and dynamic computation, and traditional transistors, which have been designed and optimized for sequential logic operations. This calls for the development of novel computing units beyond transistors. Inspired by the high efficiency and adaptability of biological neural networks, computing systems mimicking the capabilities of biological structures are gaining more attention.

As rates of obesity rise worldwide, incidence of metabolic dysfunction-associated steatotic liver disease (MASLD), formerly referred to as nonalcoholic fatty liver disease, is increasing, worsening the burden of healthcare systems. The council of the Federation of International Societies for Pediatric Gastroenterology, Hepatology, and Nutrition (FISPGHAN) identified the topic of MASLD epidemiology, treatment, and prevention as a global priority issue to be addressed by an expert team, with the goal to describe feasible and evidence-based actions that may contribute to reducing MASLD risk. The FISPGHAN member societies nominated experts in the field.

Freshwater fishes are increasingly facing extinction. Some species will require conservation intervention such as habitat restoration and/or population supplementation through mass-release of hatchery fish. In California, USA, a number of conservation strategies are underway to increase abundance of the endangered Delta Smelt (); however, it is unclear how different estuarine conditions influence hatchery fish.

Juxtaglomerular cell tumor (JxGCT) is a rare type of renal neoplasm demonstrating morphologic overlap with some mesenchymal tumors such as glomus tumor (GT) and solitary fibrous tumor (SFT). Its oncogenic drivers remain elusive, and only a few cases have been analyzed with modern molecular techniques. In prior studies, loss of chromosomes 9 and 11 appeared to be recurrent.

Antiangiogenic drugs may cause vascular normalization and correct hypoxia in tumors, shifting cells to mitochondrial respiration as the primary source of energy. In turn, the addition of an inhibitor of mitochondrial respiration to antiangiogenic therapy holds potential to induce synthetic lethality. This study evaluated the mitochondrial inhibitor ME-344 in combination with bevacizumab in patients with refractory metastatic colorectal cancer (mCRC).

Objective: Obsessive-compulsive disorder (OCD) is associated with altered brain function related to processing of negative emotions. To investigate neural correlates of negative valence in OCD, we pooled fMRI data of 633 individuals with OCD and 453 healthy controls from 16 studies using different negatively-valenced tasks across the ENIGMA-OCD Working-Group.
Methods: Participant data were processed uniformly using HALFpipe, to extract voxelwise participant-level statistical images of one common first-level contrast: negative vs.

Objectives: Outpatient follow-up visits are often recommended for children with ambulatory care-sensitive conditions (ACSCs) who are discharged from emergency departments or urgent care centers (acute care settings). We sought to assess whether attending a follow-up visit within 7 days is associated with seeking initial office-based care rather than acute care during a subsequent ACSC illness. Understanding this association is crucial to guide recommendations for routine short-term follow-up visits in children who seek acute care for these common conditions.

Enhanced recovery after surgery (ERAS) protocols have informed perioperative care across multiple surgical specialties, optimizing patient outcomes through surgical stress management and accelerated recovery. This study evaluates the familiarity and adoption of ERAS elements among craniofacial and oral and maxillofacial surgeons in pediatric orthognathic surgery, a field where a formal ERAS protocol has not been established. A closed-ended survey of 102 surgeons was conducted to assess familiarity with and utilization of 14 ERAS elements.

Background: Traumatic rib fractures are associated with pain lasting weeks to months and a decreased ability to inspire deeply or cough to clear secretions. Ultrasound-guided percutaneous cryoneurolysis involves reversibly ablating peripheral nerve(s) using exceptionally low temperature with a transdermal probe, resulting in a prolonged nerve block with a duration measured in months. We hypothesized that cryoneurolysis would improve analgesia and inspired volume following rib fracture.

Transfer RNA (tRNA) is one of the most abundant RNA types in cells, acting as an adaptor to bridge the genetic information in mRNAs with the amino acid sequence in proteins. Both tRNAs and small fragments processed from them play many nonconventional roles in addition to translation. tRNA molecules undergo various types of chemical modifications to ensure the accuracy and efficiency of translation and regulate their diverse functions beyond translation.
