Characterizing medical decision-making in sickle cell disease during childhood: Qualitative perspectives of caregivers.

Introduction: Sickle cell disease (SCD) is the most common genetic disorder among children. As the most common type of SCD, sickle cell anemia (SCA) is associated with severe complications across the lifespan. As parents/caregivers hold primary disease management responsibility during childhood, their involvement in disease management activities, including medical decision-making, is critical to successful and timely management of pediatric SCD.

Understanding barriers to well-child visit attendance among racial and ethnic minority parents.

Objectives: To assess racial and ethnic minority parents' perceptions about barriers to well-child visit attendance.

Methods: For this cross-sectional qualitative study, we recruited parents of pediatric primary care patients who were overdue for a well-child visit from the largest safety net healthcare organization in central Massachusetts to participate in semi-structured interviews. The interviews focused on understanding potential knowledge, structural, and experiential barriers for well-child visit attendance.

A Qualitative Study of Maternal Perceptions of Stress and Parenting During Early Childhood.

Objective: Exposure to maternal stress in early childhood can increase risk for learning and behavior challenges. We sought to gain in-depth understanding of how mothers perceive stressors to impact child wellbeing and identify mothers' strategies for navigating stressors with their young children.

Methods: We recruited English- and Spanish-speaking mothers from a primary care clinic serving predominantly publicly insured children.

Addressing adverse social determinants of health in pediatric primary care: Study protocol for a hybrid type 2 effectiveness-implementation randomized controlled trial in two national pediatric practice-based research networks.

Background: Growing evidence linking social determinants of health (SDOH) to child health outcomes has prompted widespread recommendations for pediatricians to screen and refer for adverse SDOH at primary care visits. Yet there is little evidence to date demonstrating the effectiveness of practice-based SDOH screening and referral interventions on increasing family engagement with resources. This hybrid type 2 effectiveness-implementation trial aims to demonstrate the non-inferiority of a low-touch implementation strategy in order to facilitate dissemination of an existing SDOH screening and referral system (WE CARE) and demonstrate its effectiveness and sustainability in various pediatric practices.

Immunosuppressive low-density neutrophils in the blood of cancer patients display a mature phenotype.

The presence of human neutrophils in the tumor microenvironment is strongly correlated to poor overall survival. Most previous studies have focused on the immunosuppressive capacities of low-density neutrophils (LDN), also referred to as granulocytic myeloid-derived suppressor cells, which are elevated in number in the blood of many cancer patients. We observed two types of LDN in the blood of lung cancer and ovarian carcinoma patients: CD45 LDN, which suppressed T-cell proliferation and displayed mature morphology, and CD45 LDN, which were immature and non-suppressive.
