Impact of Maternal Anxiety on Human Milk Macronutrients Content: A Prospective Observational Study.

The impact of maternal anxiety on the macronutrients content of human milk (HM) is unknown. We hypothesized that maternal stress generated by her infant's hospitalization will affect the mother's breast milk's macronutrients content. HM samples (2-3 mL) were collected from 21 mothers whose infants were hospitalized for 2-3 days between August 2016 and November 2017 due to neonatal fever.

A 4-MicroRNA signature can discriminate primary lymphomas from anaplastic carcinomas in thyroid cytology smears.

Background: Anaplastic thyroid carcinoma (ATC) and primary thyroid lymphoma (PTL) are uncommon tumors of the thyroid gland with several overlapping clinical and pathologic features that may render their differentiation difficult in fine-needle aspiration (FNA) cytology. MicroRNA (miRNA) signatures have been recently reported as useful diagnostic tools applied to cytology specimens.

Methods: Smears of 23 ATCs, 14 PTLs, and 20 non-neoplastic materials with multinodular goiter (MNG) were retrieved and classified based on their cytologic features and flow cytometric profiles.

The miR-17-92 microRNA cluster: a novel diagnostic tool in large B-cell malignancies.

Diffuse large B-cell lymphoma (DLBCL) can present as de novo or can arise through the transformation of many indolent lymphomas, including follicular lymphoma (FL). The morphological differentiation between germinal center-DLBCL (GC-DLBCL) and high-grade (grade 3) FL could be challenging; the accurate sub-classification of large B-cell lymphomas is mandatory in order to select the most appropriate among the new-targeted therapies. Recent expression profiling studies reported microRNAs (miRNAs) (and miR-17-92 cluster, in particular) as useful tools in differentiating DLBCL and FL.
