Inhibition of Retinal Neovascularization by BEZ235: Targeting the Akt/4EBP1/Cyclin D1 Pathway in Endothelial Cells.
Invest Ophthalmol Vis Sci
January 2025
Institute of Ophthalmology, School of Medicine, Jinan University, Guangzhou, China.
Purpose: To investigate the therapeutic efficacy of BEZ235, a dual PI3K/mTOR inhibitor, in suppressing pathological neovascularization in an oxygen-induced retinopathy (OIR) mouse model and explore the role of cyclin D1 in endothelial cell cycle regulation.
Methods: Single-cell RNA sequencing was performed to analyze gene expression and cell-cycle alterations in retinal endothelial cells under normoxic and OIR conditions. The effects of BEZ235 on human umbilical vein endothelial cells (HUVECs) and human retinal microvascular endothelial cells (HRMECs) were evaluated by assessing cell viability, cell-cycle progression, proliferation, migration, and tube formation.
Survival Among Patients With ERBB2-Positive Metastatic Breast Cancer and Central Nervous System Disease.
JAMA Netw Open
January 2025
Department of Neurosurgery and Brain Metastasis Center, Memorial Sloan Kettering Cancer Center, New York, New York.
Importance: Approximately one-third of patients with ERBB2 (formerly HER2 or HER2/neu)-positive (ERBB2+) metastatic breast cancer (MBC) develop brain metastasis. It is unclear whether patients with disease limited to the central nervous system (CNS) have different outcomes and causes of death compared with those with concomitant extracranial metastasis.
Objective: To assess overall survival (OS) and CNS-related mortality among patients with ERBB2+ breast cancer and a diagnosis of CNS disease by disease distribution (CNS only vs CNS plus extracranial metastasis).
Behavioural and psychological symptoms of people with dementia in acute hospital settings: a systematic review and meta-analysis.
Age Ageing
January 2025
Centre for Psychiatry and Mental Health, Wolfson Institute of Population Health, Queen Mary University of London, London, E13 8SP, United Kingdom of Great Britain and Northern Ireland.
Background: Behavioural and psychological symptoms of dementia (BPSD) can complicate acute hospital care, but evidence on BPSD in this setting is heterogeneous.
Objective: To determine the prevalence of BPSD in acute hospitals and explore related risk factors, treatments, and outcomes (PROSPERO: CRD42023406294).
Methods: We conducted a systematic review and meta-analysis by searching Cochrane Library, MEDLINE, and PsycINFO for studies on BPSD prevalence among older people with dementia during their acute hospital admissions (up to 5 March 2024).
Application of artificial intelligence to ultrasound imaging for benign gynecological disorders: systematic review.
Ultrasound Obstet Gynecol
January 2025
Dipartimento Scienze della Salute della Donna, del Bambino e di Sanità Pubblica, Fondazione Policlinico Universitario Agostino Gemelli, IRCCS, Rome, Italy.
Objective: Although artificial intelligence (AI) is increasingly being applied to ultrasound imaging in gynecology, efforts to synthesize the available evidence have been inadequate. The aim of this systematic review was to summarize and evaluate the literature on the role of AI applied to ultrasound imaging in benign gynecological disorders.
Methods: Web of Science, PubMed and Scopus databases were searched from inception until August 2024.
Novel insights into estimating the postmortem interval: red cell distribution width - standard deviation.
Forensic Sci Med Pathol
January 2025
Department of Forensic Medicine, Graduate School of Medicine, Kyoto Prefectural University of Medicine, 465 Kajiicho, Kawaramachi-dori Hirokoji-agaru, Kamigyo-ku, Kyoto, 602-8566, Japan.
Estimation of the postmortem interval (PMI) is highly significant, and many estimation methods have been developed. However, as no estimation method is determinate, several methods must be combined to achieve an accurate estimation. Therefore, the more methods available, the more accurate the estimation.
