Update on Pulmonary Toxicity Induced by New Breast Cancer Treatments.

In recent years, new anticancer drugs have been investigated and approved for the treatment of breast cancer based on improved survival outcomes. However, these new treatments have specific class-related side effects. Pulmonary toxicity has been identified as an adverse event of special interest with everolimus, and is becoming an increasingly significant clinical challenge with the recent approval of trastuzumab deruxtecan.

CohortDiagnostics: Phenotype evaluation across a network of observational data sources using population-level characterization.

Objective: This paper introduces a novel framework for evaluating phenotype algorithms (PAs) using the open-source tool, Cohort Diagnostics.

Materials And Methods: The method is based on several diagnostic criteria to evaluate a patient cohort returned by a PA. Diagnostics include estimates of incidence rate, index date entry code breakdown, and prevalence of all observed clinical events prior to, on, and after index date.

Ablation of PI3Kγ in neurons protects mice from diet-induced obesity MASLD and insulin resistance.

Mice with genetic ablation of PI3Kγ are protected from diet-induced obesity. However, the cell type responsible for PI3Kγ action in obesity remains unknown. We generated mice with conditional deletion of PI3Kγ in neurons using the nestin promoter to drive the expression of the Cre recombinase (PI3Kγ mice) and investigated their metabolic phenotype in a model of diet-induced obesity.

Genetic predisposition to altered blood cell homeostasis is associated with glioma risk and survival.

Glioma is a highly fatal and heterogeneous brain tumor with few known risk factors. Our study examines genetically predicted variability in blood cell indices in relation to glioma risk and survival in 3418 cases and 8156 controls. We find that increased platelet to lymphocyte ratio (PLR) confers an increased risk of glioma (odds ratio (OR) = 1.

Isolation and characterisation of a heparosan capsular polysaccharide and a core oligosaccharide from Moraxella lincolnii strain CCUG 52988.

Moraxella lincolnii is a Gram-negative bacterium that resides in the upper respiratory tract (URT) of humans and may have a role as a member of a protective microbial community. Structural characterisation studies of its outer membrane glycan structures are very limited. We report here the isolation and structural characterisation (NMR, GLC-MS) of a capsular polysaccharide (CPS) and an oligosaccharide (OS) (lipooligosaccharide (LOS)-derived) isolated from strain CCUG 52988.
