Risk Factors Associated With Intracranial Hemorrhage In Neonates With Persistent Pulmonary Hypertension On Ecmo, S. Doymaz, M. Zinger, T. Sweberg

Journal Articles

BACKGROUND: Up to 40% of infants with persistent pulmonary hypertension (PPHN) remains refractory to conventional therapies, and extracorporeal membrane oxygenation (ECMO) is offered as an effective support for this group. However, ECMO is a highly invasive and risky procedure with devastating complications such as intracranial hemorrhage (ICH). In this study, we aimed to determine the risk factors for ICH in infants with PPHN. METHODS: A case-control study of patients admitted to the pediatric intensive care unit (PICU) with PPHN requiring ECMO support was conducted. The study was carried out at a 25-bed PICU in large urban tertiary care children's hospital. …

Many Mendelian traits are likely unrecognized owing to absence of traditional segregation patterns in families due to causation by de novo mutations, incomplete penetrance, and/or variable expressivity. Genome-level sequencing can overcome these complications. Extreme childhood phenotypes are promising candidates for new Mendelian traits. One example is early onset hypertension, a rare form of a global cause of morbidity and mortality. We performed exome sequencing of 40 unrelated subjects with hypertension due to primary aldosteronism by age 10. Five subjects (12.5%) shared the identical, previously unidentified, heterozygous CACNA1H(M1549V) mutation. Two mutations were demonstrated to be de novo events, and all mutations …

Tat-Hsp70 Attenuates Experimental Lung Injury, M. M. Lyons, N. N. Raj, J. L. Chittams, L. Kilpatrick, C. S. Deutschman

Journal Articles

Sepsis, a poorly understood syndrome of disordered inflammation, is the leading cause of death in critically ill patients. Lung injury, in the form of acute respiratory distress syndrome (ARDS), is the most common form of organ injury in sepsis. The heat shock response, during which heat shock proteins (HSPs) are expressed, is an endogenous mechanism to protect cells from injury. We have found that the abundance of pulmonary HSP70 is not increased after cecal ligation and double puncture (CLP) in a rat model of sepsis-induced ARDS. Using the HIV-1 trans-activator of transcription (TAT) cell-penetrating protein, we enhanced HSP70 protein abundance …


A Self-Paced Oral Feeding System That Enhances Preterm Infants' Oral Feeding Skills, C. Lau, S. Fucile, R. J. Schanler Jan 2015

A Self-Paced Oral Feeding System That Enhances Preterm Infants' Oral Feeding Skills, C. Lau, S. Fucile, R. J. Schanler

Journal Articles

AIM: Very low birth weight (VLBW) infants have difficulty transitioning to independent oral feeding, be they breast- or bottle-feeding. We developed a 'self-paced' feeding system that eliminates the natural presence of the positive hydrostatic pressure and internal vacuum build-up within a bottle during feeding. Such system enhanced these infants' oral feeding performance as monitored by overall transfer (OT; % ml taken/ml prescribed), rate of transfer (RT; ml/min over an entire feeding). This study hypothesizes that the improvements observed in these infants resulted from their ability to use more mature oral feeding skills (OFS). METHODS: 'Feeders and growers' born between 26-29 …

Journal Articles

BACKGROUND: Therapeutic hypothermia is recommended for comatose adults after witnessed out-of-hospital cardiac arrest, but data about this intervention in children are limited. METHODS: We conducted this trial of two targeted temperature interventions at 38 children's hospitals involving children who remained unconscious after out-of-hospital cardiac arrest. Within 6 hours after the return of circulation, comatose patients who were older than 2 days and younger than 18 years of age were randomly assigned to therapeutic hypothermia (target temperature, 33.0 degrees C) or therapeutic normothermia (target temperature, 36.8 degrees C). The primary efficacy outcome, survival at 12 months after cardiac arrest with a …

Journal Articles

At its June 2015 meeting, the Advisory Committee on Immunization Practices (ACIP) recommended that adolescents and young adults aged 16-23 years may be vaccinated with a serogroup B meningococcal (MenB) vaccine to provide short-term protection against most strains of serogroup B meningococcal disease. This report summarizes the deliberations of ACIP, the rationale for its decision, and recommendations for use of MenB vaccines in adolescents and young adults. Two MenB vaccines have recently been licensed by the Food and Drug Administration (FDA) for use in the United States and approved for use in persons aged 10-25 years: MenB-FHbp (Trumenba, Wyeth Pharmaceuticals, …

Choledochal Cyst Mimicking Gallbladder With Stones In A Six-Year-Old With Right-Sided Abdominal Pain, R. Subramony, N. Kittisarapong, I. Barata, M. Nelson

Journal Articles

Choledochal cysts are rare but serious bile duct abnormalities are found in young children, usually during the first year of life.1 They require urgent surgical intervention due to the risk of developing cholangiocarcinoma.2 Clinicians should consider this diagnosis and perform a point-of-care ultrasound (POCUS) when a child presents to the emergency department (ED) with findings of jaundice, abdominal pain, and the presence of an abdominal mass. We present the case of a six-year-old child presenting only with abdominal pain upon arrival to our ED and was ultimately diagnosed by POCUS to have a choledochal cyst.


Immune Dysregulation In Patients Persistently Infected With Human Papillomaviruses 6 And 11, A. V. Lucs, J. A. Devoti, L. Hatam, A. Afzal, A. L. Abramson, B. M. Steinberg, V. R. Bonagura Jan 2015

Immune Dysregulation In Patients Persistently Infected With Human Papillomaviruses 6 And 11, A. V. Lucs, J. A. Devoti, L. Hatam, A. Afzal, A. L. Abramson, B. M. Steinberg, V. R. Bonagura

Journal Articles

Human Papillomaviruses (HPVs) 6 and 11 are part of a large family of small DNA viruses, some of which are commensal. Although much of the population can contain or clear infection with these viruses, there is a subset of individuals who develop persistent infection that can cause significant morbidity and on occasion mortality. Depending on the site of infection, patients chronically infected with these viruses develop either recurrent, and on occasion, severe genital warts or recurrent respiratory papillomas that can obstruct the upper airway. The HPV-induced diseases described are likely the result of a complex and localized immune suppressive milieu …

Journal Articles

BACKGROUND: Mesenchymal stem cells (MSCs) have been proposed as autologous therapy for inflammatory diseases in neonates. MSCs from umbilical cord Wharton's jelly (WJ-MSCs) are accessible, with high proliferative capacity. The effects of WJ-MSCs on neutrophil activity in neonates are not known. We compared the effects of WJ-MSCs on apoptosis and the expression of inflammatory, oxidant, and antioxidant mediators in adult and neonatal neutrophils. METHODS: WJ-MSCs were isolated, and their purity and function were confirmed by flow cytometry. Neutrophils were isolated from cord and adult blood by density centrifugation. The effects of neutrophil/WJ-MSC co-culture on apoptosis and gene and protein expression …

Judging Quality Of Current Septic Shock Definitions And Criteria, M. Shankar-Hari, G. Bertolini, F. M. Brunkhorst, R. Bellomo, D. Annane, C. S. Deutschman, M. Singer

Journal Articles

Septic shock definitions are being revisited. We assess the feasibility, reliability, and validity characteristics of the current definitions and criteria of septic shock. Septic shock is conceptualised as cardiovascular dysfunction, tissue perfusion and cellular abnormalities caused by infection. Currently, for feasibility, septic shock is identified at the bedside by using either hypotension or a proxy for tissue perfusion/cellular abnormalities (e.g., hyperlactatemia). We propose that concurrent presence of cardiovascular dysfunction and perfusion/cellular abnormalities could improve validity of septic shock diagnosis, as we are more likely to identify a patient population with all elements of the illness concept. This epidemiological refinement should …

Mitochondrial Dysfunction In Peripheral Blood Mononuclear Cells In Pediatric Septic Shock, S. L. Weiss, M. A. Selak, F. Tuluc, J. Perales Villarroel, V. M. Nadkarni, C. S. Deutschman, L. B. Becker

Journal Articles

OBJECTIVES: Mitochondrial dysfunction in peripheral blood mononuclear cells has been linked to immune dysregulation and organ failure in adult sepsis, but pediatric data are limited. We hypothesized that pediatric septic shock patients exhibit mitochondrial dysfunction within peripheral blood mononuclear cells which in turn correlates with global organ injury. DESIGN: Prospective observational study. SETTING: Academic PICU. PATIENTS: Thirteen pediatric patients with septic shock and greater than or equal to two organ failures and 11 PICU controls without sepsis or organ failure. INTERVENTIONS: Ex vivo measurements of mitochondrial oxygen consumption and membrane potential (DeltaPsim) were performed in intact peripheral blood mononuclear cells …

Intellectual disability (ID) affects approximately 1%-3% of humans with a gender bias toward males. Previous studies have identified mutations in more than 100 genes on the X chromosome in males with ID, but there is less evidence for de novo mutations on the X chromosome causing ID in females. In this study we present 35 unique deleterious de novo mutations in DDX3X identified by whole exome sequencing in 38 females with ID and various other features including hypotonia, movement disorders, behavior problems, corpus callosum hypoplasia, and epilepsy. Based on our findings, mutations in DDX3X are one of the more common …


Antigen-Based Immunotherapy For Autoimmune Disease: Current Status, D. L. Hirsch, P. Ponda Jan 2015

Antigen-Based Immunotherapy For Autoimmune Disease: Current Status, D. L. Hirsch, P. Ponda

Journal Articles

Autoimmune diseases are common chronic disorders that not only have a major impact on the quality of life but are also potentially life-threatening. Treatment modalities that are currently favored have conferred signifcant clinical benefts, but they may have considerable side effects. An optimal treatment strategy for autoimmune disease would specifcally target disease-associated antigens and limit systemic side effects. Similar to allergen-specifc immunotherapy for allergic rhinitis, antigen-specifc immunotherapy for autoimmune disease aims to induce immune deviation and promote tolerance to specifc antigens. In this review, we present the current status of studies and clinical trials in both human and animal hosts …
