Decoding Acute Myeloid Leukemia: A Clinician's Guide to Functional Profiling.

Acute myeloid leukemia (AML) is a complex clonal disorder characterized by clinical, genetic, metabolomic, and epigenetic heterogeneity resulting in the uncontrolled proliferation of aberrant blood-forming precursor cells. Despite advancements in the understanding of the genetic, metabolic, and epigenetic landscape of AML, it remains a significant therapeutic challenge. Functional profiling techniques, such as BH3 profiling (BP), gene expression profiling (GEP), proteomics, metabolomics, drug sensitivity/resistance testing (DSRT), CRISPR/Cas9, and RNAi screens offer valuable insights into the functional behavior of leukemia cells.

Improving the accuracy of reporting Ki-67 IHC by using an AI tool.

Ki-67 proliferative index (PI) scoring is measured by estimating the proportion of the number of active cell nuclei in hotspot regions within immunohistochemical (IHC) stained slides. It provides valuable information about the rate of proliferation in a tumour. Manual scoring of Ki-67 PI is laborious, time-consuming and often the victim of interobserver variability between pathologists.

Branched-chain amino acids promote hepatic Cyp7a1 expression and bile acid synthesis via suppressing FGF21-ERK pathway.

Branched-chain amino acids (BCAAs) including leucine, isoleucine and valine have been linked with metabolic and cardiovascular diseases. BCAAs homeostasis is tightly controlled by their catabolic pathway. BCKA dehydrogenase (BCKD) complex is the rate-limiting step for BCAA catabolism.

Delphi definition of general practice/family medicine specialty for a post-COVID world: in-person and remote care delivery.

Introduction: The evolving landscape of general practice (GP)/family medicine (FM) in the post-COVID-19 era, focussing on integrating telemedicine and remote consultations requires a new definition for this specialty. Hence, a broader consensus-based definition of post-COVID-19 GP/FM is warranted.

Methods: This study involved a modified electronic Delphi technique involving 27 specialists working in primary care recruited via convenient and snowball sampling.

Rediscovering publicly available single-cell data with the DISCO platform.

Single-cell RNA sequencing (scRNA-seq) has emerged as the key technique for studying transcriptomics at the single-cell level. In our previous work, we presented the DISCO database (https://www.immunesinglecell.

Differential contributions of fetal mononuclear phagocytes to Zika virus neuroinvasion versus neuroprotection during congenital infection.

Fetal immune cell functions during congenital infections are poorly understood. Zika virus (ZIKV) can vertically transmit from mother to fetus, causing nervous system infection and congenital ZIKV syndrome (CZS). We identified differential functional roles for fetal monocyte/macrophage cell types and microglia in ZIKV dissemination versus clearance using mouse models.

Neurodegenerative Diseases: Molecular Mechanisms and Therapies 2nd Edition.

Neurodegenerative disorders are multiple chronic neurological diseases that pose a serious public health risk to our society, especially among the aging population [...

Clinical Outcomes of Tube Feeding vs. Hand Feeding in Advanced Dementia.

Dementia is a growing public health issue, with the number of cases projected to triple by 2050 as society ages. Although the American Geriatrics Society recommends careful hand feeding over tube feeding for patients with advanced dementia, an increasing proportion of patients are receiving tube feeding. Although decisions regarding tube feeding are often based on the physician, recent studies have shown that tube feeding has significant implications for clinical outcomes and quality of life.

Real-World Outcomes for Localised Gastro-Oesophageal Adenocarcinoma Cancer Treated with Perioperative FLOT and Prophylactic GCSF Support in a Single Asian Centre.

Background: Perioperative FLOT (5-fluorouracil, oxaliplatin and docetaxel) is a standard of care for patients with locally advanced gastro-oesophageal adenocarcinoma (GEA) in Western guidelines, but its use is limited in Asian patients. We report outcomes from a single Asian centre of perioperative FLOT with concomitant granulocyte colony-stimulating factor (GCSF) prophylaxis.

Methods: A retrospective analysis of all 56 stage II to III GEA patients treated with perioperative FLOT at the National Cancer Centre Singapore between June 2017 and February 2024 was performed.

Therapeutic vulnerabilities and pan-cancer landscape of BRAF class III mutations in epithelial solid tumors.

Background: Kinase-impaired class III BRAF mutations have recently received attention as a possible prognostic factor and therapeutic target. Class III BRAF variants differ from class I and class II mutations in terms of mechanism of pathway activation and therapeutic vulnerabilities. Genomic landscape analyses of tumors in large real-world cohorts represent a great opportunity to further characterize tumor-related molecular events and treatment vulnerabilities, however, such data is not yet available for tumors with BRAF class III mutations.
