Psychometric evaluation of the Polish adaptation of the Body Appreciation Scale-2 for Children (BAS-2C).

Positive body image is crucial in fostering self-esteem, mental well-being, and positive social functioning. However, our understanding of its development and role in school-aged children remains limited due to a scarcity of measures available for this age group across various countries and cultures. To bridge this gap, the aim of this study was to adapt the Body Appreciation Scale-2 for Children (BAS-2C) for Polish children aged 8-13 years.

Tumor location matters, next generation sequencing mutation profiling of left-sided, rectal, and right-sided colorectal tumors in 552 patients.

Despite the introduction of new molecular classifications, advanced colorectal cancer (CRC) is treated with chemotherapy supplemented with anti-EGFR and anti-VEGF targeted therapy. In this study, 552 CRC cases with different primary tumor locations (250 left side, 190 rectum, and 112 right side) were retrospectively analyzed by next generation sequencing for mutations in 50 genes. The most frequently mutated genes were TP53 in left-sided tumors compared to right-sided tumors and BRAF in right-sided tumors compared to left-sided tumors.

Depressive and anxiety symptom trajectories in Polish adolescents during the COVID-19 pandemic and the outbreak of war in Ukraine: uncovering the role of family relations.

Introduction: The aim of the study was to investigate longitudinal trajectories of change in anxiety and depression symptoms in Polish adolescents during the second year of the COVID-19 pandemic and after the outbreak of the war in Ukraine. Additionally, we aimed to identify risk/protective factors and outcomes associated with these trajectories.

Method: We collected data in three waves between November 2021 and May 2022.

The construction and preliminary validation of a new Pictorial Materialism Test for 4-6-year-old children.

Materialistic tendencies may originate in early childhood, and previous research shows that even preschoolers differ in the degree of their materialism. The goal of this project was to develop and validate a new instrument that reliably measures materialism in preschool children (4-6 years old). A simple and universal Pictorial Materialism Test (PMT) was created and its psychometric properties were evaluated.

Alterations in key signaling pathways in sinonasal tract melanoma. A molecular genetics and immunohistochemical study of 90 cases and comprehensive review of the literature.

Sinonasal mucosal melanoma is a rare tumor arising within the nasal cavity, paranasal sinuses, or nasopharynx (sinonasal tract). This study evaluated 90 cases diagnosed in 29 males and 61 females with median age 68 years. Most tumors involved the nasal cavity and had an epithelioid morphology.
