Spatial Profiling Reveals Equivalence-Derived Molecular Signatures of Brain Mimicry and Adaptation in Breast Cancer Brain Metastases.

Brain metastases (BrMets), common for advanced-stage breast cancer patients, are associated with poor median survival and accompanied by severe neurologic decline. Halting the progression of breast cancer brain metastases (BCBMs) may require modulation of the tumor microenvironment (TME), yet little is known about the impact of the primary breast TME on brain tropism, or how, once there, metastatic breast cancer cells coexist with brain-resident cells (e.g.

Hospital discharges (MBDS) for Takotsubo syndrome in Spain. Regional differences (2008-2021).

Background And Objectives: Takotsubo syndrome (TTS) is an infrequent cause of acute coronary syndrome much better diagnosed in recent years. This study sought to assess the clinical profile of patients admitted with TTS in Spain and to elucidate potential regional differences in admissions and in-hospital mortality between the years 2008 and 2021.

Methods: Retrospective observational study of patients admitted to acute general hospitals of the Spanish National Health System with a main or secondary diagnosis of STT, using the minimum basic data set.

Exposure to environmentally relevant levels of DEHP during development modifies the distribution and expression patterns of androgen receptors in the anterior pituitary in a sex-specific manner.

DEHP is a prevalent phthalate with wide industrial applications and well-documented endocrine-disrupting effects, including the potential disruption of AR signaling in different tissues. The present study aimed to investigate the effects of gestational and lactational exposure to environmentally relevant DEHP concentrations on AR expression and subcellular localization in the pituitary gland, the master endocrine organ, with a focus on gonadotroph cells by in vivo and in vitro approaches. After DEHP exposure during gestation and lactation, a sex-specific modulation was detected in AR-positive pituitary cells and AR protein expression as assessed through flow cytometry and western blot.

A hidden enemy: Understanding the hemophagocytic syndrome in children under five years of age in a high-complexity institution in southwestern Colombia.

Introduction. Hemophagocytic syndrome is an under-recognized condition with high mortality in the pediatric population. It is characterized by excessive activation of immune cells and cytokine release, leading to persistent inflammation.

Non-cystic fibrosis bronchiectasis in pediatrics: A cohort profile of patients with inborn errors of immunity at a referral center in Cali, Colombia.

Introduction. Inborn errors of immunity are frequently associated with bronchiectasis. The diagnostic performance of these inborn errors has improved because the association of some of these entities with progressive airway damage is better known.
