A Longitudinal Investigation of Trans and Nonbinary Youth Identity: Individual Processes and Family Agreement in the Trans Teen and Family Narratives Project.

Few studies have focused on transgender and nonbinary youths' (TNBY) gender development and even less well understood is how family members understand TNBY identity. The current study investigated: a) how TNBY describe their gender identity over time, and b) how family members understand TNBY gender identity over time. The baseline sample included 96 members of 33 families (33 TNBY, 48 cisgender caregivers, 15 siblings) from the United States; 30 families continued after Wave 1.

Ethnic and racial differences in children and young people with respiratory and neurological post-acute sequelae of SARS-CoV-2: an electronic health record-based cohort study from the RECOVER Initiative.

Background: Children from racial and ethnic minority groups are at greater risk for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, but it is unclear whether they have increased risk for post-acute sequelae of SARS-CoV-2 (PASC). Our objectives were to assess whether the risk of respiratory and neurologic PASC differs by race/ethnicity and social drivers of health.

Methods: We conducted a retrospective cohort study of individuals <21 years seeking care at 24 health systems across the U.

Mixed lipopeptide-based mucosal vaccine candidate induces cross-variant immunity and protects against SARS-CoV-2 infection in hamsters.

The global dissemination of SARS-CoV-2 led to a worldwide pandemic in March 2020. Even after the official downgrading of the COVID-19 pandemic, infection with SARS-CoV-2 variants continues. The rapid development and deployment of SARS-CoV-2 vaccines helped to mitigate the pandemic to a great extent.

Non-invasive quantification of bone (re) modeling dynamics in adults with osteogenesis imperfecta treated with Setrusumab using timelapse HR-pQCT.

Timelapse imaging using high-resolution peripheral quantitative computed tomography (HR-pQCT) has emerged as a noninvasive method to quantify bone (re)modelling. However, there is no consensus on how to perform the procedure. As part of the ASTEROID phase-2b multicenter trial, we used 29 same-day repeated scans from adults with osteogenesis imperfecta (OI) to identify a method that minimized measurement error.

Photoluminescent Properties of Tb-UiO-66 Metal-Organic Framework Analogues.

Three new analogues of Tb-UiO-66 with various functional groups (-F, -Br, -NH) on the terephthalic acid linker of the metal-organic framework (MOF) are synthesized and characterized. The photoluminescent properties of these analogues, as well as Tb-UiO-66 and Tb-UiO-66-(OH), are studied and correlated to the calculated energies for the triplet (T) states of each linker. The results show that the addition of electron withdrawing groups, such as -F and -Br, lead to higher T energies, resulting in quantum yields in the range of 6-31%.

Influence of π-π interactions on organic photocatalytic materials and their performance.

Currently, organic photocatalyst-based photocatalysis has garnered significant attention as an environmentally friendly and sustainable reaction system due to the preferable structural flexibility and adjustable optoelectronic features of organic photocatalysts. In addition, π-π interactions, as one of the common non-bonded interactions, play an important role in the structure and property adjustments of organic photocatalysts due to their unique advantages in modulating the electronic structure, facilitating charge migration, and influencing interfacial reactions. However, studies summarizing the relationship between the π-π interactions of organic photocatalysts and their photocatalytic performance are still rare.

A Sox2 Enhancer Cluster Regulates Region-Specific Neural Fates from Mouse Embryonic Stem Cells.

Sex-determining region Y box 2 (Sox2) is a critical transcription factor for embryogenesis and neural stem and progenitor cell (NSPC) maintenance. While distal enhancers control Sox2 in embryonic stem cells (ESCs), enhancers closer to the gene are implicated in Sox2 transcriptional regulation in neural development. We hypothesize that a downstream enhancer cluster, termed Sox2 regulatory regions 2-18 (SRR2-18), regulates Sox2 transcription in neural stem cells and we investigate this in NSPCs derived from mouse ESCs.

Informal Caregiving: Health System Cost Implications.

Background: Informal caregiving is seen as a low-cost substitute for care provided by health care professionals. However, caregiving is known to negatively impact caregivers' health and, subsequently, their health care use and costs. This could potentially offset the caregivers' contributions to the health care system.

The role of diagnostic modalities in differentiating hypertensive heart disease and hypertrophic cardiomyopathy: strategies in adults for potential application in paediatrics.

Hypertensive heart disease and hypertrophic cardiomyopathy both lead to left ventricular hypertrophy despite differing in aetiology. Elucidating the correct aetiology of the presenting hypertrophy can be a challenge for clinicians, especially in patients with overlapping risk factors. Furthermore, drugs typically used to combat hypertensive heart disease may be contraindicated for the treatment of hypertrophic cardiomyopathy, making the correct diagnosis imperative.

lobal egistry of dverse linical vents (GRACE): A Prospective, Multicenter, Observational Cohort Evaluating Complications Associated with Aesthetic Injectables.

Background: A review of Health Canada's post-market surveillance database has revealed that the reporting of adverse events (AEs) following aesthetic injectable treatments is significantly underreported. To increase reporting, investigators have recently developed a novel Electronic Data Capture system: The Global Registry of Adverse Clinical Events (GRACE).

Objective: To identify the incidence of AEs associated with aesthetic injectable treatments.

EXPRESS: Activation of the Motor System Following Gaze Cues is Determined by Hand Access, Not Hand Proximity.

The influence of gaze cues on target prioritization (reaction times (RTs)) and movement execution (movement trajectories) differs based on the ability of the human gaze cue model to manually interact with the targets. Whereas gaze cues consistently impacted RTs, movement trajectories may only be affected when the hands of the human model had the potential to interact with the target. However, the perceived ability to interact with the targets was confounded by the proximity between the model's hands and the targets.

Assessing the Effects of Immune Checkpoint Inhibitors on Bone Utilizing Machine Learning-assisted Opportunistic Quantitative Computed Tomography.

Immune checkpoint inhibitors (ICI) are widely used in cancer treatment, yet their impact on bone health remains unclear. This study aimed to perform a retrospective cohort study utilizing routine computed tomography (CT) scans from patients with melanoma to perform opportunistic quantitative CT (QCT) analysis to investigate the effects of ICI treatment on skeletal health, including volumetric bone mineral density (vBMD) measurements and osteoarthritis (OA) parameters. A previously established machine-learning assisted opportunistic QCT pipeline was used to estimate lumbar spine vBMD from baseline and 12-month follow-up CT scans in patients with melanoma treated with ICI therapy and those not treated with ICI therapy.

Vancomycin-resistant Enterococcus prevalence and its association along the food chain: a systematic review and meta-analysis.

Background: Vancomycin-resistant Enterococcus (VRE) are present across the One Health continuum and pose a considerable risk for transmission along the food chain. This systematic review and meta-analysis estimates the prevalence of VRE colonization in livestock, food of animal origin, and in human populations.

Methods: Embase, MEDLINE and CAB Abstracts were searched for eligible literature.

Agricultural Landscape Genomics to Increase Crop Resilience.

Populations are continually adapting to their environment. Knowledge of which populations and individuals harbor unique and agriculturally useful variation has the potential to accelerate crop adaptation to the increasingly challenging environments predicted for the coming century. Landscape genomics, which identifies associations between environmental and genomic variation, provides a means for obtaining this knowledge.

Understanding social behaviours across neurodiverse young people: roles of social cognition and self-regulation.

Background: Differences in social behaviours are common in young people with neurodevelopmental conditions (NDCs). Recent research challenges the long-standing hypothesis that difficulties in social cognition explain social behaviour differences.

Aims: We examined how difficulties regulating one's behaviour, emotions and thoughts to adapt to environmental demands (i.

AI-based processing of future prepared foods: Progress and prospects.

The prepared foods sector has grown rapidly in recent years, driven by the fast pace of modern living and increasing consumer demand for convenience. Prepared foods are taking an increasingly important role in the modern catering industry due to their ease of storage, transportation, and operation. However, their processing faces several challenges, including labor shortages, inefficient sorting, inadequate cleaning, unsafe cutting processes, and a lack of industry standards.

High pressure processing at different hydration levels as a tool to enhance rice bran stability and techno-functionality.

High-pressure processing (HPP) enhances food safety and shelf life by inactivating microorganisms and preserving food quality, yet its effectiveness in low-humidity environments has not been evaluated. This study investigated the effects of HPP at 500 MPa for 15 min across varying hydration levels (15, 30, 60, 77 %) on rice bran (RB), aiming to identify microbial effectiveness, besides techno-functional and physicochemical properties. HPP effectively reduced mesophilic bacteria, molds and yeast of RB at > 15 % hydration level, achieving reductions of up to 4 logarithmic cycles in the latter, nearing the detection limit of the method.

Methylmercury in subarctic amphibians: environmental gradients, bioaccumulation, and estimated flux.

Rapid warming in polar regions is causing large changes to ecosystems, including altering environmentally available mercury (Hg). Although subarctic freshwater systems have simple vertebrate communities, Hg in amphibians remains unexplored. We measured total Hg (THg) in wetland sediments and methylmercury (MeHg) in multiple life-stages (eggs to adults) of wood frogs (Rana sylvatica) and larval boreal chorus frogs (Pseudacris maculata) from up to 25 wetlands near Churchill, Manitoba (Canada), during the summers of 2018-2019.

Evolutionary constrained genes associated with autism spectrum disorder across 2,054 nonhuman primate genomes.

Background: Significant progress has been made in elucidating the genetic underpinnings of Autism Spectrum Disorder (ASD). However, there are still significant gaps in our understanding of the link between genomics, neurobiology and clinical phenotype in scientific discovery. New models are therefore needed to address these gaps.

The effect of calcium on acute sodium chloride toxicity in Daphnia species.

Chloride concentrations in freshwater are rising, with toxic effects on aquatic life. In temperate regions with cold winters, road salt used for deicing paved surfaces is a primary cause. There is evidence that water hardness can modify salt toxicity, but data are insufficient to inform policy.

Optimising patient engagement for assessing total joint arthroplasty outcomes - a randomised controlled trial.

Introduction: Patient satisfaction is a critical outcome in total joint arthroplasty (TJA), yet assessing it effectively remains a challenge due to limitations in patient-reported outcome measures (PROMS). While these measures are commonly gathered in clinical settings, additional contact through mail or phone is often needed, and low response rates can affect the validity and reliability of collected data. To improve response rates, this study evaluated various methods of incentivizing patient participation in a randomized trial format, focusing on postal questionnaires.

Association between white blood cell count and coronary artery bypass graft failure: an individual patient data analysis of clinical trials.

Background: Baseline systemic inflammation is associated with worse long-term outcomes after coronary artery bypass grafting [CABG], but the mechanisms of this association are unclear. This study aims to explore the association between pre-operative white blood cell [WBC] count and CABG graft failure.

Methods: We pooled individual patient data from two randomized clinical trials with systematic CABG graft imaging.

Social-structural barriers to primary care among sex workers: findings from a community-based cohort in Vancouver, Canada (2014-2021).

Background: Due to social-structural marginalization, sex workers experience health inequities including a high prevalence of sexually transmitted and blood-borne infections, mental health disorders, trauma, and substance use, alongside a multitude of barriers to HIV and substance use services. Given limited evidence on sex workers' broader primary healthcare access, we aimed to examine social-structural factors associated with primary care use among sex workers over 7 years.

Methods: Data were derived from An Evaluation of Sex Workers Health Access (AESHA), a community-based open prospective cohort of women (cis and trans) sex workers in Metro Vancouver, from 2014 to 2021.
