The associations between risk factors and pituitary neuroendocrine tumors: A bidirectional Mendelian randomization study.
Medicine (Baltimore)
November 2024
The Second Affiliated Hospital of Harbin Medical University, Harbin, People's Republic of China.
The etiological basis of pituitary neuroendocrine tumors is uncertain. We used Mendelian randomization technique to investigate the potential influence of several risk factors on the likelihood of developing pituitary neuroendocrine tumors. We admitted 8 risk factors, divided into 3 lifestyle factors and 5 chronic diseases as exposure factors.

Department of Radiation Oncology (Maastro), GROW Research Institute for Oncology and Reproduction, Maastricht University Medical Centre+, Maastricht, the Netherlands.
Background And Purpose: Radiotherapy for brain, head & neck (HN), and skull base (SB) tumors may deliver significant radiation dose to the hypothalamic-pituitary axis (HPA), leading to impaired functioning of this region and hence, to endocrine disorders. The purpose of this systematic review and -analysis is to investigate literature on HP dysfunction after radiation for non-pituitary brain, HN, or SB tumors at adult age, aiming to give insight in the prevalence of HP dysfunction related to radiation dose.
Materials And Methods: Literature search of the PubMed database was performed for HP dysfunction after radiotherapy in adult patients.
A hybrid explainable model based on advanced machine learning and deep learning models for classifying brain tumors using MRI images.

Brain tumors present a significant global health challenge, and their early detection and accurate classification are crucial for effective treatment strategies. This study presents a novel approach combining a lightweight parallel depthwise separable convolutional neural network (PDSCNN) and a hybrid ridge regression extreme learning machine (RRELM) for accurately classifying four types of brain tumors (glioma, meningioma, no tumor, and pituitary) based on MRI images. The proposed approach enhances the visibility and clarity of tumor features in MRI images by employing contrast-limited adaptive histogram equalization (CLAHE).

The dynamics of focal adhesions (FAs) are essential physiological processes involved in cell spreading, metastasis, and regulation of the actin cytoskeleton. FAs are complex structures comprising proteins, such as paxillin and zyxin, which interact with extracellular membranes and influence cell motility and morphology. Although related studies have been reported in various cancers, the function and molecular mechanisms of oral squamous cell carcinoma (OSCC) remain unknown.

Department of Endocrinology and Metabolism, Affiliated Hospital of Jining Medical University, Jining, Shandong, P.R. China.
Pituitary stalk lesions are uncommon and are typically identified through pituitary magnetic resonance imaging and screening for causes of diabetes insipidus. Recent literature indicates that pituitary stalk lesions primarily manifest as pituitary stalk interruption syndrome and thickening of the pituitary stalk. The etiology of these lesions is complex and can be divided into major categories: congenital disorders, inflammatory or infectious diseases, and tumors.
