Racial and ethnic inequities in paediatric care have received increased research attention over the past two decades, particularly in the past 5 years, alongside an increased societal focus on racism. In this Series paper, the first in a two-part Series focused on racism and child health in the USA, we summarise evidence on racial and ethnic inequities in the quality of paediatric care. We review studies published between Jan 1, 2017 and July 31, 2022, that are adjusted for or stratified by insurance status to account for group differences in access, and we exclude studies in which differences in access are probably driven by patient preferences or the appropriateness of intervention.

Objectives: Racial and ethnic minority children receive less care and inferior care in the United States, but less is known about how these disparities vary by mental health conditions. We examined unmet mental health needs by condition types to identify potentially hidden racial and ethnic inequities.

Methods: We used data from the nationally representative National Survey of Children's Health, from 2016 to 2021 (n = 172 107).

This study explores the family dynamics that are activated during the perinatal period and considers the potential for intervention with adolescent parents and their families in Lima, Peru.

Mammalian sirtuins have emerged in recent years as critical modulators of multiple biological processes, regulating cellular metabolism, DNA repair, gene expression, and mitochondrial biology. As such, they evolved to play key roles in organismal homeostasis, and defects in these proteins have been linked to a plethora of diseases, including cancer, neurodegeneration, and aging. In this review, we describe the multiple roles of SIRT6, a chromatin deacylase with unique and important functions in maintaining cellular homeostasis.

Oncogenic "driver" mutations are theoretically attractive targets for the immunotherapy of lymphoid cancers, yet the proportion that can be recognized by T cells remains poorly defined. To address this issue without any confounding effects of the patient's immune system, we assessed T cells from 19 healthy donors for recognition of three common driver mutations in lymphoma: , and . Donors collectively expressed the 10 most prevalent HLA class I alleles, including HLA-A*02:01.
