Current Opinion in Pediatrics was launched in 1989. It is one of a successful series of review journals whose unique format is designed to provide a systematic and critical assessment of the literature as presented in the many primary journals. The field of pediatrics is divided into 18 sections that are reviewed once a year. Each section is assigned a Section Editor, a leading authority in the area, who identifies the most important topics at that time. In addition to this, Henry H. Bernstein also invites a prominent authority in the field of Office Pediatrics to write on the subject for each issue. Here we are pleased to introduce the Section Editors for this issue.

Sally RadovickSally RadovickSally Radovick, MD, is the Henry Rutgers Term Chair and Professor of Pediatrics and Senior Associate Dean for Clinical and Translational Research at Rutgers-Robert Wood Johnson Medical School, USA. Prior to this position, she was the Division Director of Pediatric Endocrinology and the Vice-Chair for Research in the Department of Pediatrics at Johns Hopkins University School of Medicine, USA. She received her medical degree from Northeastern Ohio Universities College of Medicine, USA, completed her residency in pediatrics at Case Western Reserve University, USA, and her fellowship in pediatric endocrinology at the National Institutes of Health (NIH). Dr Radovick is a specialist in growth and development and pubertal disorders in children. Her research is focused on determining the regulation of the gonadotropin-releasing hormone (GnRH) gene, which has a central role in controlling the onset of puberty. Her group was the first to generate GnRH-expressing neuronal cell lines and in vitro map the cellular regulation of this critical gene by growth factors that have increased knowledge of the relationship between growth, puberty, and nutrition. She has developed genetically modified mouse models to elucidate mechanisms of in vivo regulation of GnRH secretion in response to neuroendocrine and growth factor stimulation and sex steroid feedback regulation. She has been particularly interested in determining the roles of neurotransmitter/hormone receptors in mediating the increase in GnRH secretion to adult levels at puberty, which results in the attainment of fertility. These studies will provide insights into pubertal disorders and PCOS, as well as provide future therapies for infertility. With recent evidence implicating the neuroendocrine protein kisspeptin, responsible for the pubertal onset and reproductive cycling with obesity and metabolism, Dr Radovick has begun exploring novel roles for peripheral kisspeptins in the control of metabolic homeostasis. The other major research area has been to characterize the transcription factors important for normal pituitary development. Her initial studies provided the first genetic mechanism of a child with short stature due to hypopituitarism; this involved a mutation in the Pit-1 gene necessary for pituitary cell lineage determination and differentiation. She has described the mechanisms by which novel mutations in other pituitary-specific transcription factors are responsible for pituitary hormone deficiencies. She is the curator of a tissue repository for patients with hypopituitarism. The NIH has continuously supported these studies since 1992, currently including an R01 to determine the role of sex steroids in puberty and reproductive cycling and a U01 collaborative agreement with investigators at the NIH Clinical Center to determine the genetics of short stature. Dr Radovick has authored or co-authored more than 100 peer-reviewed scientific publications and has been invited to write a dozen book chapters in her field. She is an author of “Puberty in the female and its disorders” in Sperling's textbook, Pediatric Endocrinology, and “Normal and aberrant growth” in Williams Textbook of Endocrinology. She serves as the Associate Editor of Pediatric Endocrinology and as Editor of Pituitary, while also serving as Section Editor for Current Opinion in Pediatrics. Dr Radovick served as the President of the Pediatric Endocrine Society, the Chair of the Research Council, a Council member, and Chair of the Drug and Therapeutics Committee. She was also a member of the Endocrine Society Guidelines Committee and Finance Committee and a co-author of the AACE Growth Hormone Guidelines. She was the recipient of the Human Growth Foundation (HGF) inaugural Blizzard Award in 2022. She is currently the Chair of the Integrative and Clinical Endocrinology and Reproduction (ICER) NIH study section. Dr Radovick has trained over 75 predoctoral students, postdoctoral fellows, and junior faculty in scientific research and is the PI of the Rutgers CTSA KL2 program. She has remained clinically active during her career, focusing on children with disorders of growth and puberty and precepting teaching clinics in Pediatric Endocrinology. Henry H. BernsteinHenry H. BernsteinDr Bernstein is a Professor of Pediatrics at Zucker School of Medicine at Hofstra/Northwell in New York, USA. He taps into his extensive 36–year experience as a general pediatrician in private practice, the National Health Service Corps, and as Chief of General Academic Pediatrics at urban, suburban, and rural children's hospitals to promote the health and well-being of children, their families, and their communities. His private, community-based primary care (generalist) experiences in combination with academic leadership responsibilities have provided him with a value-added, translational science perspective, unique from many others in academia. This tacit knowledge enables him to fulfil a lifelong passion of communicating, educating, and translating science into clinical settings, educational venues, policy-making, and media interactions to advance the health of children. Research is consistently woven into the fabric of Dr Bernstein's clinical practice, which has served as a “laboratory” for his active studies. His research and quality improvement initiatives focus on issues important to Academic General Pediatrics and community-based practice, including immunizations, infectious diseases, postpartum newborn discharge, childhood obesity, breastfeeding, health promotion, preventive health screening in primary care, technology and medical education. His commitment, innovative spirit, and enthusiasm also encompass many facets of medical education along the continuum from training and mentoring future physicians to fostering lifelong learning and supporting the continuous professional development of practicing pediatricians. Dr Bernstein is Associate Editor of the American Academy of Pediatrics’ (AAP) Red Book Online (www.aapredbook.org) and a former voting member of the Centers for Disease Control and Prevention's (CDC) Advisory Committee on Immunization Practice (ACIP). He serves as a consultant on the ACIP COVID-19, Influenza, and Immunization Schedules for Adults and Children workgroups. He is also an ex-officio member of the AAP's Committee on Infectious Diseases (Red Book Committee). In addition, he is Editor-in-Chief Emeritus of PediaLink (www.pedialink.aap.org), the AAP's online home for lifelong learning, and Chair of the interdisciplinary Bright Futures Health Promotion Workgroup, which created a distinctive health promotion curriculum, videos, and a companion educational website (www.pediatricsinpractice.org). Dr Bernstein has been Editor of the Office Pediatrics Series in Current Opinion in Pediatrics since 1995 and was Senior Editor of Pediatrics on the public website of Harvard Medical School's Health Publications Division for 17 years. He regularly shares his knowledge and expertise by educating the public, writing for health information websites and often participating in media interviews on a variety of pediatric health care issues including immunizations, diagnosis and treatment of common childhood infectious diseases and conditions, as well as practical information for parents, teachers and caregivers. In the spirit of lifelong learning, Dr Bernstein earned a masters in healthcare management (MHCM) at Harvard T. H. Chan School of Public Health, USA in 2013 and has been a faculty member in this Executive Education Masters degree program since. He actively maintains his certification by the American Board of Pediatrics. He completed his residency training in pediatrics at St. Christopher's Hospital for Children in Philadelphia, USA after earning his medical degree from the University of Medicine and Dentistry of New Jersey - School of Osteopathic Medicine, USA.
