Determination of prognosis in oncology practice is a major challenge and many histological prognosticators have been applied because of the ease and simplicity of using them in day-to-day practice. Our histopathologic observation on 96 oral squamous cell carcinoma (OSCC) specimens revealed 34 cases associated with frank hemorrhagic areas, which were close to tumor cells. Hence, we propose that there could be a cross-talk between tumor cells and RBCs which can modulate the biological behavior of the tumor and prognosis of the patient. In the present paper, a scientific foundation is provided for this proposition. Furthermore, an experimental approach is recommended which will facilitate the identification of extracellular metabolites within the tumor microenvironment near RBCs. Such studies may pave the way for a better understanding of the clinical heterogeneity of oral cancer due to differential heme content of red blood cells (RBCs) in the tumor microenvironment (TME).

Background: Primary hypertension (PH) poses significant risks to children and adolescents. Few prediction models for the risk of PH in children and adolescents currently exist, posing a challenge for doctors in making informed clinical decisions.
Objective: This study aimed to investigate the incidence and risk factors of PH in Chinese children and adolescents.

Introduction: Solid pseudopapillary neoplasm (SPN) is a rare pancreatic tumor typically occurring in young females. This case presents an instance of SPN in a 54-year-old Caucasian female, highlighting atypical age of onset and providing new insights into the tumor's clinical and histopathological diversity.
Case Report: A 54-year-old female with no significant past medical history presented with upper abdominal discomfort and weakness.
Context: Anemia is a medical condition resulting from a reduction in the number of red blood cells below the reference range. It is a major public health problem, particularly among adolescents, as it can have negative effects on cognitive performance, growth and reproduction. This study aims to assess the determinants of anemia among adolescents in schools in the city of Douala.

Purpose: In Aotearoa New Zealand, there are inequitable outcomes for Pacific peoples who experience higher rates of preventable cancers and poorer survival compared with other ethnicities. The aim of this study was to explore Pacific peoples lived experience of cancer and its treatment in the Auckland setting.
Methods: Data were collected through semistructured interviews (talanoa) with Pacific patients under the Auckland Regional Cancer and Blood Service.
Improving the reliability and accuracy of population receptive field measures using a logarithmically warped stimulus.

The population receptive field (pRF) method, which measures the region in visual space that elicits a blood-oxygen-level-dependent (BOLD) signal in a voxel in retinotopic cortex, is a powerful tool for investigating the functional organization of human visual cortex with fMRI (Dumoulin & Wandell, 2008). However, recent work has shown that pRF estimates for early retinotopic visual areas can be biased and unreliable, especially for voxels representing the fovea. Here, we show that a log-bar stimulus that is logarithmically warped along the eccentricity dimension produces more reliable estimates of pRF size and location than the traditional moving bar stimulus.
