Objective: Benefit-finding and growth is an important process across a range of medical populations. However, it has been understudied in the context of lifelong chronic conditions, such as spina bifida (SB). This study aimed to develop a new measure of benefit-finding and growth for youth with SB, confirm its factor structure, and examine its psychometric properties.

Article Synopsis
  • Bladder cancer incidence and mortality rates have remained stable over the past 20 years, with around 40% of high-risk nonmuscle invasive cases recurring or progressing.
  • In 2021, an estimated 83,532 newly diagnosed bladder cancer patients in the USA faced treatment costs totaling approximately $2.6 billion, with costs varying significantly by disease stage.
  • The economic analysis indicates that treating recurrent cases adds about $3.9 billion, leading to a total estimated treatment cost exceeding $6.5 billion for both newly diagnosed and recurrent patients, highlighting the financial impact of the disease.

Epitaxial graphene/ferromagnetic metal (Gr/FM) heterostructures deposited onto heavy metals have been proposed for the realization of spintronic devices because of their perpendicular magnetic anisotropy and sizable Dzyaloshinskii-Moriya interaction (DMI), allowing for both enhanced thermal stability and stabilization of chiral spin textures. However, establishing routes toward this goal requires the fundamental understanding of the microscopic origin of their unusual properties. Here, we elucidate the nature of the induced spin-orbit coupling (SOC) at Gr/Co interfaces on Ir.

Background: The recently discovered glymphatic system may support the removal of neurotoxic proteins, mainly during sleep, that are associated with neurodegenerative diseases such as Alzheimer's and Parkinson's Disease. Diffusion tensor image analysis along the perivascular space (DTI-ALPS) has been suggested as a method to index the health of glymphatic system (with higher values indicating a more intact glymphatic system). Indeed, in small-scale studies the DTI-ALPS index has been shown to correlate with age, cognitive health, and sleep, and is higher in females than males.

Objective: This study aims to characterize the growth in condition-related knowledge in youth with spina bifida (SB), identify neurocognitive predictors of growth, and examine associations between growth in knowledge and subsequent levels of medical self-management skills.

Methods: Participants were recruited from a larger longitudinal study involving 140 youth with SB and caregivers, who completed questionnaires and interviews every 2 years over 8 years. The current study included the youth report of condition-related knowledge and medical self-management skills.

Municipal biosolids are a nitrogen (N)-rich agricultural fertilizer which may emit nitrous oxide (NO) after rainfall events. Due to sparse empirical data, there is a lack of biosolids-specific NO emission factors to determine how land-applied biosolids contribute to the national greenhouse gas inventory. This study estimated NO emissions from biosolids-amended land in Canada using Tier 1, Tier 2 (Canadian), and Tier 3 (Denitrification and Decomposition model [DNDC]) methodologies recommended by the Intergovernmental Panel on Climate Change (IPCC).

To estimate the incidence, prevalence and treated prevalence by line of therapy (LOT) for non-small-cell lung cancer (NSCLC) patients without driver mutations from 2021 to 2026. Country-specific registry data for Western Europe were used to project incidence and prevalence of NSCLC; LOT information was obtained from CancerMPact Treatment Architecture physician surveys. Incidence, prevalence and treated prevalence across LOTs for NSCLC are projected to increase across five WE countries, including for stage IV patients without driver mutations (184,966 cases [2021] to 197,925 [2026]).

Objective: To determine the relationship between constructive adolescent problem solving (positive problem-solving orientation and rational problem-solving style) and caregiver problem solving and collaborative involvement with primary caregiver among adolescents with spinal cord injuries (SCIs). Positive constructive adolescent problem solving was hypothesized to be predicted by more effective caregiver problem solving and higher collaborative involvement.

Methods: Participants in this cross-sectional study were 79 adolescent and primary caregiver dyads recruited from a pediatric rehabilitation care system in North America.

Objective: Cognitive disengagement syndrome (CDS; formally known as sluggish cognitive tempo), difficulties with social engagement, and lower levels of autonomy have been identified as maladaptive comorbidities in youth with spina bifida (SB). This study compared growth curves of CDS for youth with and without SB and examined whether these trajectories were associated with later functioning.

Methods: Longitudinal data spanning 8 years included youth with SB (n = 68, Mage = 8.

Three-dimensional Dirac semimetals are an exotic state of matter that continue to attract increasing attention due to the unique properties of their low-energy excitations. Here, by performing angle-resolved photoemission spectroscopy, we investigate the electronic structure of Au_{2}Pb across a wide temperature range. Our experimental studies on the (111)-cleaved surface unambiguously demonstrate that Au_{2}Pb is a three-dimensional Dirac semimetal characterized by the presence of a bulk Dirac cone projected off-center of the bulk Brillouin zone (BZ), in agreement with our theoretical calculations.

The interplay of nontrivial topology and superconductivity in condensed matter physics gives rise to exotic phenomena. However, materials are extremely rare where it is possible to explore the full details of the superconducting pairing. Here, we investigate the momentum dependence of the superconducting gap distribution in a novel Dirac material PdTe.

Finding stimuli capable of driving an imbalance of spin-polarised electrons within a solid is the central challenge in the development of spintronic devices. However, without the aid of magnetism, routes towards this goal are highly constrained with only a few suitable pairings of compounds and driving mechanisms found to date. Here, through spin- and angle-resolved photoemission along with density functional theory, we establish how the p-derived bulk valence bands of semiconducting 1T-HfSe possess a local, ground-state spin texture spatially confined within each Se-sublayer due to strong sublayer-localised electric dipoles orientated along the c-axis.

Artificial graphene based on molecular networks enables the creation of novel 2D materials with unique electronic and topological properties. Landau quantization has been demonstrated by CO molecules arranged on the two-dimensional electron gas on Cu(111) and the observation of electron quantization may succeed based on the created gauge fields. Recently, it was reported that instead of individual manipulation of CO molecules, simple deposition of nonpolar C molecules on Cu(111) and Au(111) produces artificial graphene as evidenced by Dirac cones in photoemission spectroscopy.

The Fermi surface plays an important role in controlling the electronic, transport and thermodynamic properties of materials. As the Fermi surface consists of closed contours in the momentum space for well-defined energy bands, disconnected sections known as Fermi arcs can be signatures of unusual electronic states, such as a pseudogap. Another way to obtain Fermi arcs is to break either the time-reversal symmetry or the inversion symmetry of a three-dimensional Dirac semimetal, which results in formation of pairs of Weyl nodes that have opposite chirality, and their projections are connected by Fermi arcs at the bulk boundary.
