Paediatric renal tumours: an update on challenges and recent developments.

Paediatric renal tumours include a broad range of neoplasms which largely differ, but also overlap to a smaller extent, with adult kidney cancer. These include the embryonal tumour nephroblastoma, which accounts for the majority of cases of kidney cancer in the first decade of life and, despite boasting a cure in ~ 90% cases, still presents clinical challenges in a small proportion of cases. A variety of less common mesenchymal tumours, including the mostly indolent congenital mesoblastic nephroma, clear cell sarcoma of kidney which continues to be associated with poor outcomes for higher stage disease, and the typically lethal malignant rhabdoid tumour, form the bulk of the remaining presentations in the first decade.

Lessons learned from the COVID-19 pandemic: identifying hesitant groups and exploring reasons for vaccination hesitancy, from adolescence to late adulthood.

Introduction: The COVID-19 (COronaVIrus Disease-2019) pandemic highlighted the importance of assessing the rationales behind vaccine hesitancy for the containment of pandemics. In this nationwide study, representative of the Luxembourgish population, we identified hesitant groups from adolescence to late adulthood and explored motivations both for and against vaccination.

Methods: We combined data collected via online surveys for the CON-VINCE (COvid-19 National survey for assessing VIral spread by Non-affected CarriErs) study, 1865 respondents aged 18-84, and for the YAC (Young people And Covid-19) study, 3740 respondents aged 12-29.

Heterostructure growth, electrical transport and electronic structure of crystalline Dirac nodal arc semimetal PtSn.

Topological semimetals have recently garnered widespread interest in the quantum materials research community due to their symmetry-protected surface states with dissipationless transport which have potential applications in next-generation low-power electronic devices. One such material, [Formula: see text], exhibits Dirac nodal arcs and although the topological properties of single crystals have been investigated, there have been no reports in crystalline thin film geometry. We examined the growth of [Formula: see text] heterostructures on a range of single crystals by optimizing the electron beam evaporation of Pt and Sn and studied the effect of vacuum thermal annealing on phase and crystallinity.

Allergen Specific IgE is a Stronger Predictor of Remission Following Peanut Oral Immunotherapy Than Age in Children Aged 1-10 Years.

Background: Remission is the desired outcome following OIT as it allows individuals to discontinue treatment and eat the allergen freely. Early initiation of OIT in infants and toddlers has been embraced as an approach to increase the likelihood of remission. However, there is no high-quality evidence supporting younger age as an independent factor driving remission; available studies are limited by small samples of younger subjects and lack of adjustment for confounding covariates, particularly peanut-specific IgE (sIgE) levels which is closely correlated with age.

Low latency carbon budget analysis reveals a large decline of the land carbon sink in 2023.

In 2023, the CO growth rate was 3.37 ± 0.11 ppm at Mauna Loa, which was 86% above that of the previous year and hit a record high since observations began in 1958, while global fossil fuel CO emissions only increased by 0.
