The "Silent" Threat: Group G Streptococcus Peritonitis in Peritoneal Dialysis.

Peritoneal dialysis (PD) is a therapy for patients with end-stage renal disease (ESRD). PD carries an increased risk of peritonitis, often secondary to poor technique. A small subset of patients may present with "silent" peritonitis, or peritonitis in the absence of fever and abdominal pain, making diagnosis and treatment challenging.

Integrating the Teaching and Assessment of Moral Reasoning into Undergraduate Medical Education to Advance Health Equity.

Moral reasoning skills among medical students have regressed despite the implementation of ethics teachings in medical education curricula. This inability to retain moral reasoning capability is attributed to difficulty transitioning to the principled thinking stage of moral reasoning as well as worsening of ethical decision-making skills during clerkship education due to the "hidden curriculum." Prior studies have examined the efficacy of individual strategies for moral education, but there is insufficient analysis comparing multiple educational interventions and moral reasoning assessment tools.

Cellular and Humoral Immune Responses after Immunisation with Low Virulent African Swine Fever Virus in the Large White Inbred Babraham Line and Outbred Domestic Pigs.

African swine fever virus is currently present in all of the world's continents apart from Antarctica, and efforts to control the disease are hampered by the lack of a commercially available vaccine. The Babraham large white pig is a highly inbred line that could represent a powerful tool to improve our understanding of the protective immune responses to this complex pathogen; however, previous studies indicated differential vaccine responses after the African swine fever virus challenge of inbred minipigs with different swine leukocyte antigen haplotypes. Lymphocyte numbers and African swine fever virus-specific antibody and T-cell responses were measured in inbred and outbred animals after inoculation with a low virulent African swine fever virus isolate and subsequent challenge with a related virulent virus.

Primary Macrophage Culture from Porcine Blood and Lungs.

Primary cultures represent the most reliable method to isolate and propagate field isolates of African swine fever virus (ASFV ). Within the pig ASFV predominantly targets the reticuloendothelial system for replication; therefore, primary macrophage cell cultures are commonly used to isolate, propagate, and study the virus life cycle in the laboratory. In this chapter we will describe methods for the direct isolation of pulmonary alveolar macrophages by lung lavage and the culture of monocyte-derived macrophages from pig blood.

Attention control in a trial of an online psychoeducational intervention for caregivers.

In reports of randomized controlled trials, thorough description of the attention control condition has been recommended, yet is frequently lacking. The Tele-Savvy Caregiver program for informal caregivers of persons living with dementia was tested in a randomized controlled trial with an attention control condition. The purpose of this trial was to test Tele-Savvy's efficacy in reducing the negative effects of caregiving on caregivers, promoting quality of life for persons living with dementia, and improving caregiver mastery.

Results of a Randomized Trial Testing the Efficacy of Tele-Savvy, an Online Synchronous/Asynchronous Psychoeducation Program for Family Caregivers of Persons Living with Dementia.

Background And Objectives: Family caregivers will grow in number as dementia prevalence increases, underscoring the continued importance of equipping these individuals for their new roles and ameliorating the adverse effects of caregiving.

Research Design And Methods: A three-armed, waitlist, randomized trial design tested Tele-Savvy, an online adaptation of a successful in-person psychoeducation program, the Savvy Caregiver. Tele-Savvy is delivered over 43 days to groups of 6-8 caregivers in 7 weekly synchronous sessions accompanied by 36 brief asynchronous video lessons.

Using a Warm Hand-Off Approach to Enroll African American Caregivers in a Multi-Site Clinical Trial: The Handshake Protocol.

"Testing Tele-Savvy" was a three-arm randomized controlled trial that recruited participants from four National Institute on Aging (NIA)-funded Alzheimer's Disease Centers with Emory University serving as the coordinating center. The enrollment process involved each center providing a list of eligible caregivers to the coordinating center to consent. Initially, the site proposed to recruit primarily African American caregivers generated a significant amount of referrals to the coordinating center, but a gap occurred in translating them into enrolled participants.

Identification and Immunogenicity of African Swine Fever Virus Antigens.

African swine fever (ASF) is a lethal haemorrhagic disease of domestic pigs for which there is no vaccine. Strains of the virus with reduced virulence can provide protection against related virulent strains of ASFV, but protection is not 100% and there are concerns about the safety profile of such viruses. However, they provide a useful tool for understanding the immune response to ASFV and previous studies using the low virulent isolate OUR T88/3 have shown that CD8+ cells are crucial for protection.

Curve Characteristics and Foraminal Dimensions in Patients With Adult Scoliosis and Radiculopathy.

Study Design: Retrospective cohort study.

Objective: To demonstrate a correlation between radiculopathy symptoms, foraminal morphology, and curve types.

Summary Of Background Data: Patients with degenerative scoliosis frequently present with foraminal stenosis and radiculopathy, the origin of which is not well understood.

A randomised controlled trial to assess the clinical effectiveness and cost-effectiveness of alternative treatments to Inhibit VEGF in Age-related choroidal Neovascularisation (IVAN).

Background: Bevacizumab (Avastin®, Roche), which is used in cancer therapy, is the 'parent' molecule from which ranibizumab (Lucentis®, Novartis) was derived for the treatment of neovascular age-related macular degeneration (nAMD). There were reports in the literature on the effectiveness of bevacizumab in treating nAMD, but no trials. The cost per dose of bevacizumab is about 5-10% that of ranibizumab.

Pediatric Spine Trauma in the United States--Analysis of the HCUP Kid'S Inpatient Database (KID) 1997-2009.

Background: Few references are available describing the epidemiology of pediatric spine injuries. The purpose of this study is to examine the prevalence, risk factors and trends during the period from 1997 to 2009 of pediatric spine injuries in the United States using a large national database.

Methods: Data was obtained from the Kid's Inpatient Database (KID) developed by the Healthcare Cost and Utilization Project (HCUP), for the years 1997-2009.

High levels of polo-like kinase 1 and phosphorylated translationally controlled tumor protein indicate poor prognosis in neuroblastomas.

Despite multimodality treatment, the long-term survival of high-risk patients with neuroblastomas is below 50%. New anti-mitotic drugs against targets, such as polo-like kinase 1 (PLK1), are being evaluated in early phase clinical trials. PLK1 phosphorylates the translationally controlled tumor protein (TCTP).

Propofol cardioplegia: A single-center, placebo-controlled, randomized controlled trial.

Objectives: Cardiac surgery with cardiopulmonary bypass and cardioplegic arrest is an effective treatment for coronary artery and aortic valve diseases. However, the myocardium sustains reperfusion injury after ischemic cardioplegic arrest. Our objective was to assess the benefits of supplementing cardioplegia solution with the general anesthetic propofol in patients undergoing either coronary artery bypass grafting (CABG) or aortic valve replacement (AVR).

Transfusion Indication Threshold Reduction (TITRe2) randomized controlled trial in cardiac surgery: statistical analysis plan.

Background: The Transfusion Indication Threshold Reduction (TITRe2) trial is the largest randomized controlled trial to date to compare red blood cell transfusion strategies following cardiac surgery. This update presents the statistical analysis plan, detailing how the study will be analyzed and presented. The statistical analysis plan has been written following recommendations from the International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use, prior to database lock and the final analysis of trial data.

Aurora kinase A is superior to Ki67 as a prognostic indicator of survival in neuroblastoma.

Aims: To compare the expression and prognostic value of the cell cycle markers Aurora kinase A (AURKA) and Ki67 in neuroblastoma, because AURKA expression levels have greater prognostic significance than those of Ki67 in some cancers.

Methods And Results: Eighty-eight neuroblastomas were immunostained with anti-AURKA and Ki67 antibodies. Digitally scanned slides were scored using imaging analysis software.

Ethanol alters proliferation and differentiation of normal and chromosomally abnormal human embryonic stem cell-derived neurospheres.

Ethanol is a powerful substance and, when consumed during pregnancy, has significant psychoactive and developmental effects on the developing fetus. These abnormalities include growth retardation, neurological deficits, and behavioral and cognitive deficiencies, commonly referred to as fetal alcohol spectrum disorder. The effect of ethanol has been reported to affect cellular development on the embryonic level, however, not much is known about mutations contributing to the influence of ethanol.

VEGF-C, VEGF-D and VEGFR-3 expression in peripheral neuroblastic tumours.

Aims: More than 50% of neuroblastomas (NBs) present with haematogenous and/or lymphatic metastasis; however, little is known about the clinicopathological significance in NBs of the key lymphangiogenesis growth factors vascular endothelial growth factor (VEGF)-C and VEGF-D and the receptor VEGFR-3.

Methods And Results: Ninety-three NBs and nine ganglioneuromas (GNs) were immunostained for VEGF-C, VEGF-D and VEGFR-3. VEGF-C and VEGF-D were present in 76% and 82% of the NBs, respectively.

Study Objectives: To examine sleep health knowledge and beliefs and their relationship to sleep practices in a community sample of caregivers of young children.

Methods: A convenience sample of caregivers visiting a museum on one of 2 consecutive weekend days completed a brief parent-report survey on child sleep habits and parental basic sleep knowledge and beliefs and attitudes regarding sleep as a health behavior.

Results: Of the 253 analyzable surveys (response rate 80%; mean age of index child 3.

GABRB3 gene expression increases upon ethanol exposure in human embryonic stem cells.

Ionotropic receptors are the target for most mood-defining compounds. Chronic exposure to ethanol (EtOH) alters receptor-mediated responses and the numbers of these channels and specific subunits; as well as induces anxiolytic, sedative, and anesthetic activity in the human brain. However, very little is known regarding the effects of EtOH on ionotropic receptor transcription during early human development (preimplantation).

Low ethanol concentration alters CHRNA5 RNA levels during early human development.

Alcohol use is common and consumption during pregnancy has been shown to lead to a myriad of physical and neurologic abnormalities commonly referred to as fetal alcohol spectrum disorder. Substance addiction, which includes alcohol, has been shown to involve the major nicotinic acetylcholine receptor subunit CHRNA5. Using human embryonic stem cells as a model of early human development, we show that low concentrations of ethanol (20mM) can alter the expression of CHRNA5.

Heparin binding epidermal growth factor-like growth factor reduces ethanol-induced apoptosis and differentiation in human embryonic stem cells.

Alcohol affects approximately 1% (40,000) of new born infants each year and is the main preventable cause of mental retardation in the US. Ethanol alters cell signaling and promotes apoptosis and differentiation. Heparin-binding epidermal growth factor-like growth factor (HB-EGF), a member of the EGF family of growth factors, has been reported to prevent apoptosis and differentiation.
