The Spatial Distribution of Brain Metastasis Is Determined by the Heterogeneity of the Brain Microenvironment.
Hum Brain Mapp

It is now understood that brain metastases do not occur randomly but have distinct spatial patterns depending on the origin of the cancer. According to the "seed and soil" hypothesis, the final colonization of metastatic cells is the result of their adaptation to the altered environment. To investigate the most favorable microenvironment for brain metastasis, we analyzed neuroimaging data from 177 patients with breast cancer brain metastasis and 548 patients with lung cancer brain metastasis to create a replicable probabilistic map of metastatic locations.

Division of Cardiology, Baylor Scott & White Medical Center, Temple, TX.
Undifferentiated pleomorphic sarcoma, an exceedingly rare and aggressive primary cardiac tumor arising from mesenchymal stem cells, is associated with poor prognosis and high mortality despite adequate treatment. A 52-year-old female presented with a 2-month history of angina and dyspnea on exertion. Her clinical history included severe acute respiratory syndrome coronavirus 2 myocarditis and iron deficiency anemia.

Background: Chronic Obstructive Pulmonary Disease (COPD), mainly caused by cigarette smoking, is one of the leading causes of death in the United States (US) and frequent asthma attacks are often exacerbated by cigarette use. Electronic cigarettes (e-cigarettes) are often used to quit cigarette smoking. Prevalence of COPD, asthma, cigarette use, and e-cigarette use differs between racial/ethnic groups.

National Lung Hospital, 463 Hoang Hoa Tham, Ba Dinh, Hanoi, Viet Nam.
Introduction: Carnitine Palmitoyltransferase II (CPT II) deficiency encompasses a spectrum of disorders, with the lethal neonatal form (LNF) representing the rarest and most severe. While there are numerous gene variants that can cause CPT II deficiency, only 16 variants of these are known to be associated with LNF. This report presents the case of a neonatal male diagnosed with lethal CPT II deficiency, characterized by the presence of two heterogeneous variants.

Front Immunol
December 2024
State Key Laboratory of Trauma and Chemical Poisoning, Department of Stem Cell and Regenerative Medicine, Daping Hospital, Army Medical University, Chongqing, China.
Background: To determine the role of N-methyladenosine (mA) modification in the tumor immune microenvironment (TIME), as well as their association with lung adenocarcinoma (LUAD).
Methods: Consensus clustering was performed to identify the subgroups with distinct immune or mA modification patterns using profiles from TCGA. A risk score model was constructed using least absolute shrinkage and selection operator regression and validated in two independent cohorts and LUAD tissue microarrays.
