    AbstractChildren with single-ventricle disease experience high mortality and complex care. In other life-limiting childhood illnesses, paediatric palliative care may mitigate maternal stress. We hypothesised that early palliative care in the single-ventricle population may have the same benefit for mothers. In this pilot randomised trial of early palliative care, mothers of infants with prenatal single-ventricle diagnoses completed surveys measuring depression, anxiety, coping, and quality of life at a prenatal visit and neonatal discharge. Infants were randomised to receive early palliative care ā€“ structured evaluation, psychosocial/spiritual, and communication support before surgery ā€“ or standard care. Among 56 eligible mothers, 40 enrolled and completed baseline surveys; 38 neonates were randomised, 18 early palliative care and 20 standard care; and 34 postnatal surveys were completed. Baseline Beck Depression Inventory-II and State-Trait Anxiety Index scores exceeded normal pregnant sample scores (mean 13.76Ā±8.46 versus 7.0Ā±5.0 and 46.34Ā±12.59 versus 29.8Ā±6.35, respectively; p=0.0001); there were no significant differences between study groups. The early palliative care group had a decrease in prenatal to postnatal State-Trait Anxiety Index scores (āˆ’7.6 versus 0.3 in standard care, p=0.02), higher postnatal Brief Cope Inventory positive reframing scores (p=0.03), and a positive change in PedsQL Family Impact Module communication and family relationships scores (effect size 0.46 and 0.41, respectively). In conclusion, these data show that mothers of infants with single-ventricle disease experience significant depression and anxiety prenatally. Early palliative care resulted in decreased maternal anxiety, improved maternal positive reframing, and improved communication and family relationships.</jats:p

    Mental health concerns are associated with worse outcomes after adult heart transplant. Illnessā€specific anxiety is associated with worsened psychological wellā€being after other solid organ transplants but has never been characterized after pediatric heart transplant. This singleā€center crossā€sectional study aimed to evaluate illnessā€specific and generalized anxiety after heart transplantation in adolescents. A novel 12ā€item PHTF, GADā€7, and the PedsQL were administered. Univariate associations of demographics, clinical features, and medication adherence as measured by immunosuppression standard deviation with the PHTF and GADā€7 scores were evaluated. Internal consistency and validity of the PHTF were examined. In total, 30 patients participated. The most common illnessā€specific fears were retransplantation, rejection, and more generally postā€transplant complications. The PHTF had good internal consistency (Cronbach Ī±Ā =Ā .88). Construct validity was demonstrated between PHTF and GADā€7 (rĀ =Ā .62) and PedsQL (rĀ =Ā āˆ’.54 to āˆ’.62). 23% endorsed moderate to severe generalized anxiety symptoms. More severe symptoms were associated with older age at survey (PĀ =Ā .03), older age at listing (PĀ =Ā .01) and having postā€transplant complications (PĀ =Ā .004). Patients with moderate or severe symptoms were more likely to report late immunosuppression doses (PĀ =Ā .004). Illnessā€specific and generalized anxiety may be prevalent after pediatric heart transplant. Screening for anxiety in adolescents postā€transplant may identify those at risk for adverse outcomes including nonā€adherence. The PHTF is a brief, valid, and reliable instrument identifying illnessā€specific anxiety in this population.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/153669/1/petr13647.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/153669/2/petr13647_am.pd

    Decreased inappropriate shocks with new generation ICDs in children and patients with congenital heart disease

    Full text link
    ObjectiveInappropriate implantable cardioverter defibrillator (ICD) shocks in children and patients with congenital heart disease (CHD) remain a major complication of device therapy, occurring in as many as 50% of children with ICDs. New generation devices include algorithms designed to minimize inappropriate shocks. This study aimed to evaluate the effect of new generation ICDs on the incidence of inappropriate shocks in the pediatric and CHD population.DesignRetrospective study of patients with CHD or under age 25 receiving ICDs between 2000 and 2015. New generation ICDs were defined as those with Medtronic ā€œSmartShockā€ algorithms.ResultsTwo hundred eight devices were implanted in 146 patients. Rates of inappropriate shocks were similar between diagnoses (P = .71). The rate of inappropriate shock was 15% over median 5.8 years followā€up. In the 36 patients (25%) with new generation ICDs, the rate of inappropriate shock was 6.3% over 4 years. Comparing old to new generation ICDs, freedom from first inappropriate shock was 90.6% versus 97.1% at 1 year and 80.4% versus 97.1% at 3 years (P = .01). Lead fracture was associated with having inappropriate shock (hazard ratio 8.5, Pā€‰<ā€‰.0001), and there was no significant difference between the device groups when lead fractures were excluded. Clinical actions were taken in 69% of patients after initial inappropriate shock (such as medication or program change, system revision, or explant). When an action was taken, subsequent inappropriate shock was reduced (5.3% vs 49.2% at 1 year; P = .002).ConclusionsPediatric and CHD patients are experiencing reduced inappropriate shocks with new generation ICD systems, though reduced lead fracture may account for this improvement. Clinical interventions after inappropriate shock favorably impact the subsequent rate of shocks once an inappropriate shock occurs.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/144309/1/chd12585_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/144309/2/chd12585.pd

    Cellular Basis of Tissue Regeneration by Omentum

    Get PDF
    The omentum is a sheet-like tissue attached to the greater curvature of the stomach and contains secondary lymphoid organs called milky spots. The omentum has been used for its healing potential for over 100 years by transposing the omental pedicle to injured organs (omental transposition), but the mechanism by which omentum helps the healing process of damaged tissues is not well understood. Omental transposition promotes expansion of pancreatic islets, hepatocytes, embryonic kidney, and neurons. Omental cells (OCs) can be activated by foreign bodies in vivo. Once activated, they become a rich source for growth factors and express pluripotent stem cell markers. Moreover, OCs become engrafted in injured tissues suggesting that they might function as stem cells

    Anisotropic nanomaterials: structure, growth, assembly, and functions

    Comprehensive knowledge over the shape of nanomaterials is a critical factor in designing devices with desired functions. Due to this reason, systematic efforts have been made to synthesize materials of diverse shape in the nanoscale regime. Anisotropic nanomaterials are a class of materials in which their properties are direction-dependent and more than one structural parameter is needed to describe them. Their unique and fine-tuned physical and chemical properties make them ideal candidates for devising new applications. In addition, the assembly of ordered one-dimensional (1D), two-dimensional (2D), and three-dimensional (3D) arrays of anisotropic nanoparticles brings novel properties into the resulting system, which would be entirely different from the properties of individual nanoparticles. This review presents an overview of current research in the area of anisotropic nanomaterials in general and noble metal nanoparticles in particular. We begin with an introduction to the advancements in this area followed by general aspects of the growth of anisotropic nanoparticles. Then we describe several important synthetic protocols for making anisotropic nanomaterials, followed by a summary of their assemblies, and conclude with major applications

    Proceedings of the 3rd Biennial Conference of the Society for Implementation Research Collaboration (SIRC) 2015: advancing efficient methodologies through community partnerships and team science

    It is well documented that the majority of adults, children and families in need of evidence-based behavioral health interventionsi do not receive them [1, 2] and that few robust empirically supported methods for implementing evidence-based practices (EBPs) exist. The Society for Implementation Research Collaboration (SIRC) represents a burgeoning effort to advance the innovation and rigor of implementation research and is uniquely focused on bringing together researchers and stakeholders committed to evaluating the implementation of complex evidence-based behavioral health interventions. Through its diverse activities and membership, SIRC aims to foster the promise of implementation research to better serve the behavioral health needs of the population by identifying rigorous, relevant, and efficient strategies that successfully transfer scientific evidence to clinical knowledge for use in real world settings [3]. SIRC began as a National Institute of Mental Health (NIMH)-funded conference series in 2010 (previously titled the ā€œSeattle Implementation Research Conferenceā€; $150,000 USD for 3 conferences in 2011, 2013, and 2015) with the recognition that there were multiple researchers and stakeholdersi working in parallel on innovative implementation science projects in behavioral health, but that formal channels for communicating and collaborating with one another were relatively unavailable. There was a significant need for a forum within which implementation researchers and stakeholders could learn from one another, refine approaches to science and practice, and develop an implementation research agenda using common measures, methods, and research principles to improve both the frequency and quality with which behavioral health treatment implementation is evaluated. SIRCā€™s membership growth is a testament to this identified need with more than 1000 members from 2011 to the present.ii SIRCā€™s primary objectives are to: (1) foster communication and collaboration across diverse groups, including implementation researchers, intermediariesi, as well as community stakeholders (SIRC uses the term ā€œEBP championsā€ for these groups) ā€“ and to do so across multiple career levels (e.g., students, early career faculty, established investigators); and (2) enhance and disseminate rigorous measures and methodologies for implementing EBPs and evaluating EBP implementation efforts. These objectives are well aligned with Glasgow and colleaguesā€™ [4] five core tenets deemed critical for advancing implementation science: collaboration, efficiency and speed, rigor and relevance, improved capacity, and cumulative knowledge. SIRC advances these objectives and tenets through in-person conferences, which bring together multidisciplinary implementation researchers and those implementing evidence-based behavioral health interventions in the community to share their work and create professional connections and collaborations

    Survey of the Air Force P78-2 (SCATHA)--satellite plasma wave data during electron gun operations

    Get PDF
    The Air Force P78-2 satellite, known as SCATHA, was designed to study spacecraft charging processes at geosynchronous orbit. This thesis examines the plasma wave data taken during two periods when active experiments were conducted with the electron gun. Emissions at the electron gyrofrequency were stimulated by the operation of the electron gun on some occasions. These indicate interaction between the electron beam and plasma at local resonant frequencies of the plasma. A major objective of this thesis is to catalogue the characteristics of the plasma wave data common to the modes of operation of the electron gun. The purpose is to provide a baseline for analysis of data not only from SCATHA, but from other spacecraft including the space shuttle orbiter. Stimulated emissions at characteristic frequencies dependent on gun current and voltage were identified. These were consistently observed during the experiment presented here, and other events analyzed but not displayed.http://archive.org/details/surveyofairforce00loweLieutenant Commander, United States NavyApproved for public release; distribution is unlimited
