Can Brain Imaging Help Predict Bipolar Disorder in High Risk Children?
 Can Brain Imaging Help Predict Bipolar Disorder in High Risk Children? 150 150 Mary Bates, PhD
By:

Patterns in connectivity in a portion of the frontal lobe called the inferior frontal gyrus appears to be an early biomarker in children of parents with bipolar disorder. Researchers report a potential neural marker of individual risk in those with a family history of bipolar disorder. The study, published in the journal Neuropsychopharmacology, points to particular…

Acid Suppression Should Not Be the First Treatment for Infants With Reflux
 Acid Suppression Should Not Be the First Treatment for Infants With Reflux 150 150 Mary Bates, PhD
By:

Gastroesophageal reflux (GER) is common in infants. Many show no symptoms more serious than agitation and frequent regurgitation, and most cases resolve on their own by the time the child is 1 year old.

Despite a paucity of well-controlled clinical trials, acid suppression medications are commonly prescribed for infants with GER. In a paper published in Pediatric Drugs, physician researchers from Nationwide Children’s Hospital review the data regarding acid suppressants for infants as well as clinical practice guidelines for how and when to use these medications.

Targeted interventions result in improved feeding efficiency and growth in infants with cleft lip and/or palate. Cleft lip and/or palate is a relatively common birth defect that occurs when certain parts of the face and mouth fail to fuse during development. Infants with the condition can struggle to suck or extract liquid from the breast…

Femoral Nerve Blockade May Reduce Need for Intravenous Opioids
 Femoral Nerve Blockade May Reduce Need for Intravenous Opioids 150 150 Mary Bates, PhD
By:

Researchers find no differences in postoperative pain measures for patients receiving intravenous opioids and those receiving regional anesthetic. Femur fractures often require surgical fixes and can be quite painful. Although traditionally treated with intravenous opioids, regional anesthesia may offer an alternative option. In a new study, published in the Journal of Pain Research, researchers evaluated the…

New guidelines will help doctors recognize and treat children at risk of venous thromboembolism. Prevention of blood clots is well described in adult cancer patients, but data on the problem in pediatric cancer patients is limited. In a new publication initiated at the request of the International Society of Thrombosis and Hemostasis, researchers provide guidance for…

A new study looks at outcomes for children with leukemia when two tests of remission disagree. In both clinical practice and clinical trials, remission in leukemia is determined by morphological assessment — a person counting cancer cells in a bone marrow sample under a microscope. But more sophisticated technologies, such as flow cytometry or polymerase…

How Genes and Environment Interact to Raise Risk of Congenital Heart Defects
 How Genes and Environment Interact to Raise Risk of Congenital Heart Defects 150 150 Mary Bates, PhD
By:

Genetic susceptibility plus maternal hyperglycemia interact to contribute to heart defects during fetal development. Infants of mothers with diabetes have a three- to five-fold increased risk of congenital heart defects. Such developmental defects are likely caused by a combination of genetic and environmental factors. However, the molecular mechanisms by which maternal diabetes disrupts normal heart…

Different Patterns of Executive Function Deficits in Different Pediatric Brain Disorders
 Different Patterns of Executive Function Deficits in Different Pediatric Brain Disorders 150 150 Mary Bates, PhD
By:

Clinical implications include specialized testing for deficits in executive function as these may not be apparent at a routine exam. A large group of researchers, including many from Nationwide Children’s Hospital, recently looked at whether children with different brain disorders show diverse patterns of strengths and weaknesses in executive functions. Children with traumatic brain injuries…

Combining Immunotherapies Effective Against Mouse Model of Cancer
 Combining Immunotherapies Effective Against Mouse Model of Cancer 150 150 Mary Bates, PhD
By:

Recent study results suggest that combining virotherapy and PD-1 blockades may be more effective than either approach alone. Rhabdomyosarcoma, a cancer made up of cells that normally develop into skeletal muscles, is the most common soft tissue cancer in children. If it is detected early and localized in certain areas, rhabdomyosarcoma is usually curable with…

Balancing Immune Activation and Suppression After Cardiopulmonary Bypass
 Balancing Immune Activation and Suppression After Cardiopulmonary Bypass 150 150 Mary Bates, PhD
By:

Understanding how the immune system responds to CPB could dramatically impact postsurgical outcomes. Cardiopulmonary bypass (CPB) is a relatively routine procedure, generally with favorable outcomes. However, among the risks posed to patients is the over- or under-activation of the immune system following the surgery.

By:

A psychological intervention improves kids’ function and quality of life even years after a concussion. For most children and adolescents that experience concussions, symptoms resolve after a week or two. However, a small subset of kids has persistent symptoms lasting for months or even years after the injury. These symptoms can be disruptive and stressful,…

By:

Insulin regulates an antimicrobial peptide that is suppressed in patients with diabetes. A recent study led by clinicians and researchers at Nationwide Children’s Hospital reports a potential explanation for why urinary tract infections (UTIs) are so common in patients with diabetes – insulin regulates an antimicrobial peptide (AMP) that is suppressed in those patients. Patients…
