Engineered cytokine/antibody fusion proteins improve IL-2 delivery to pro-inflammatory cells and promote antitumor activity.

Progress in cytokine engineering is driving therapeutic translation by overcoming these proteins' limitations as drugs. The IL-2 cytokine is a promising immune stimulant for cancer treatment but is limited by its concurrent activation of both pro-inflammatory immune effector cells and antiinflammatory regulatory T cells, toxicity at high doses, and short serum half-life. One approach to improve the selectivity, safety, and longevity of IL-2 is complexing with anti-IL-2 antibodies that bias the cytokine toward immune effector cell activation.

Application of Statistical Analysis and Machine Learning to Identify Infants' Abnormal Suckling Behavior.

Objective: Identify infants with abnormal suckling behavior from simple non-nutritive suckling devices.

Background: While it is well known breastfeeding is beneficial to the health of both mothers and infants, breastfeeding ceases in 75 percent of mother-child dyads by 6 months. The current standard of care lacks objective measurements to screen infant suckling abnormalities within the first few days of life, a critical time to establish milk supply and successful breastfeeding practices.

An Unusual Case of an ALK-Negative Epithelioid Fibrous Histiocytoma in the External Auditory Canal.

This article represents the first reported case in the external auditory canal of epithelioid fibrous histiocytoma (EFH), a rare benign cutaneous epithelioid neoplasm. Immunostaining revealed uncommon negative staining for anaplastic lymphoma kinase (ALK) expression. This case and literature review outline the diagnostic strategy for this highly unusual neoplasm.
