Comparing Generational Differences In Job Satisfaction And Retention (Anticipated Turnover) Among Nurses Working In Magnet Versus Non-Magnet Designated Hospitals, Laura E. Cima Sep 2014

Comparing Generational Differences In Job Satisfaction And Retention (Anticipated Turnover) Among Nurses Working In Magnet Versus Non-Magnet Designated Hospitals, Laura E. Cima

Seton Hall University Dissertations and Theses (ETDs)

Background and Purpose of the Study: Experts in the nursing profession predict a catastrophic nursing shortage by 2025. Nursing shortages have devastating effects on hospitals from a quality of care, patient and family satisfaction and financial perspectives. Given these issues, the most logical approach to this shortage is retention of nurses rather than recruitment. The Magnet designation is one mechanism to retain nursing staff.

Another phenomenon exists within the work environment that makes this shortage different from others. Currently, there are four generations of nurses working in the healthcare environment. Each of these generational cohorts has different values and …

Background. Lack of human immunodeficiency virus (HIV) infection awareness may be a driver of racial disparities in HIV infection among men who have sex with men (MSM). Lack of awareness is typically measured by comparing HIV test result to self-reported HIV status. This measure may be subject to reporting bias and alternatives are needed.Methods. The InvolveMENt study examined HIV disparities between black and white MSM from Atlanta. Among HIV-positive participants who did not report knowing they were positive, we examined other measures of awareness: … See full text for complete abstract.


Quantitative Assessment Of Blood Coagulation By Cold Atmospheric Plasma, Caitlin Heslin, Daniela Boehm, Vladimir Milosavljevic, Michelle Laycock, Patrick J. Cullen, Paula Bourke Sep 2014

Quantitative Assessment Of Blood Coagulation By Cold Atmospheric Plasma, Caitlin Heslin, Daniela Boehm, Vladimir Milosavljevic, Michelle Laycock, Patrick J. Cullen, Paula Bourke

Articles

Cold atmospheric plasma (CAP) is produced by ionizing a chosen gas, thereby creating charged and reactive species. The reactive species generated are capable of inducing a range of biomedically relevant interactions including blood coagulation. However, the underlying biochemical processes of plasma-assisted blood coagulation are largely unknown, and data quantifying blood clot formation or the impact of system parameters on the intensity of the blood clot are scarce. In this study, blood coagulation was quantified by measuring hemoglobin absorbance. System parameters of the kINPen plasma jet were investigated and compared, including treatment time, distance from the plasma source and gas flow …

Cardiac Fibroblasts Contribute To Myocardial Dysfunction In Mice With Sepsis: The Role Of Nlrp3 Inflammasome Activation, Wenbo Zhang, Xuemei Xu, Raymond Kao, Tina Mele, Peter Kvietys, Claudio M. Martin, Tao Rui

Anatomy and Cell Biology Publications

Myocardial contractile dysfunction in sepsis is associated with the increased morbidity and mortality. Although the underlying mechanisms of the cardiac depression have not been fully elucidated, an exaggerated inflammatory response is believed to be responsible. Nucleotide-binding oligomerization domain-like receptor containing pyrin domain 3 (NLRP3) inflammasome is an intracellular platform that is involved in the maturation and release of interleukin (IL)-1 beta. The aim of the present study is to evaluate whether sepsis activates NLRP3 inflammasome/caspase-1/IL-1 beta pathway in cardiac fibroblasts (CFs) and whether this cytokine can subsequently impact the function of cardiomyocytes (cardiac fibroblast-myocyte crosstalk). We show that treatment of …


Con: Are We Ready To Translate Alzheimer's Disease-Modifying Therapies To People With Down Syndrome?, Elizabeth Head, Frederick A. Schmitt Sep 2014

Con: Are We Ready To Translate Alzheimer's Disease-Modifying Therapies To People With Down Syndrome?, Elizabeth Head, Frederick A. Schmitt

Sanders-Brown Center on Aging Faculty Publications

BACKGROUND: Adults with Down syndrome develop Alzheimer's disease neuropathology in an age-dependent manner. This unique feature provides an opportunity to test interventions targeted for prevention of Alzheimer's disease neuropathology and dementia in Down syndrome.

DISCUSSION: In considering clinical trial designs, however, there are several challenges that we believe will be critical to examine further. These include: accuracy in dementia, mild cognitive impairment and preclinical Alzheimer's disease diagnoses in Down syndrome; clinical trial outcome measures appropriate for individuals with Down syndrome; in vivo imaging outcome measures (and practical considerations); and contributions of medical co-morbidities to disease progression. Also, when studies are …

Virus Sharing, Genetic Sequencing, And Global Health Security, Lawrence O. Gostin, Alexandra Phelan, Michael A. Stoto, John D. Kraemer, K. Srinath Reddy

Georgetown Law Faculty Publications and Other Works

The WHO’s Pandemic Influenza Preparedness (PIP) Framework was a milestone global agreement designed to promote the international sharing of biological samples to develop vaccines, while that ensuring poorer countries would have access to those vaccines. Since the PIP Framework was negotiated, scientists have developed the capacity to use genetic sequencing data (GSD) to develop synthetic viruses rapidly for product development of life-saving technologies in a time-sensitive global emergency—threatening to unravel the Framework. Access to GSD may also have major implications for biosecurity, biosafety, and intellectual property (IP).

By rendering the physical transfer of viruses antiquated, GSD may also undermine the …

School of Medicine Publications

Polycyclic aromatic hydrocarbons (PAH), like Benzo[alpha]Pyrene (BaP) are known to cause a number of toxic manifestations including lung cancer. As Titanium dioxide Nanoparticles (TiO2 NPs) have recently been shown to adsorb a number of PAHs from soil and water, we investigated whether TiO2 NPs could provide protection against the BaP induced toxicity in biological system. A549 cells when co-exposed with BaP (25 mM, 50 mM and 75 mM) along with 0.1 mg/ml,0.5 mg/ml and 1 mg/ml of TiO2 NPs, showed significant reduction in the toxic effects of BaP, as measured by Micronucleus Assay, MTT Assay and ROS Assay. In order …

Birth Centre Management And Business Skill Training For Community Midwives Of Pakistan, Laila Lalji, Laila Akbar Ali, Marina Baig, Rozina Sewani, Arusa Lakhani, Karyn Kaufman, Rafat Jan

Journal of Asian Midwives (JAM)

The Community Midwifery program was introduced in 2007 across Pakistan with the idea that the trained Community Midwives (CMWs) will be deployed back to their ‘native’ rural communities. Hence, they are not employed by government rather they must earn their income by charging fees for their services. It is expected from them to attract clients, establish birth clinics and operate as a small business to support and sustain them financially. However, the CMW training program only teaches students about antenatal, intranatal, postnatal and newborn care, family planning services and awareness of community dynamics and does not include content about setting …


Midwifery In India And Its Roadmap, Manju Chhugani Sep 2014

Midwifery In India And Its Roadmap, Manju Chhugani

Journal of Asian Midwives (JAM)

Healthy women are the key to the health of any nation. Midwifery in India has climbed up the ladder of progression from before independence till the present day. In the pre-independence era, maternal and newborn care was given by indigenous dais who not only helped during childbirth but also acted as consultants for any condition of the mother related to birth. They were midwives in the literal sense. Over the time, midwifery in India has broadened to the presence of a skilled birth attendant during childbirth. The maternal health status of women and maternal mortality are closely related to the …

Exploring Adolescent Reproductive Health Knowledge, Perceptions, And Behavior, Among Students Of Non-Government Secondary Schools Supported By Brac Mentoring Program In Rural Bangladesh, Bachera Aktar, Malabika Sarker, Andrew Jenkins

Journal of Asian Midwives (JAM)

Adolescence is the transition period from childhood to adulthood. Since Bangladesh is such a conservative society, reproductive health education for adolescents has not been widely introduced. Very small adolescent health components are included in the secondary and higher secondary school curricula. The BRAC Mentoring Program provides mentorship training to secondary school pupils to develop them as peer leaders. However, this program does not provide adolescent reproductive health education. Therefore, a study, supported by BRAC Education Program in rural Bangladesh, was conducted to explore the current status of reproductive health knowledge, perceptions and practice among the students of secondary schools. This …

Differential Spatial Repositioning Of Activated Genes In Biomphalaria Glabrata Snails Infected With Schistosoma Mansoni, Halime D. Arican-Goktas, Wannaporn Ittiprasert, Joanna M. Bridger, Matty Knight

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Schistosomiasis is an infectious disease infecting mammals as the definitive host and fresh water snails as the intermediate host. Understanding the molecular and biochemical relationship between the causative schistosome parasite and its hosts will be key to understanding and ultimately treating and/or eradicating the disease. There is increasing evidence that pathogens that have co-evolved with their hosts can manipulate their hosts' behaviour at various levels to augment an infection. Bacteria, for example, can induce beneficial chromatin remodelling of the host genome. We have previously shown in vitro thatBiomphalaria glabrata embryonic cells co-cultured with schistosome miracidia display genes changing their …

Integrating Stages Of Change Models To Cast New Vision On Interventions To Improve Global Retinoblastoma And Childhood Cancer Outcomes, Meaghann S. Weaver, Christina L. Heminger, Catherine G. Lam Sep 2014

Integrating Stages Of Change Models To Cast New Vision On Interventions To Improve Global Retinoblastoma And Childhood Cancer Outcomes, Meaghann S. Weaver, Christina L. Heminger, Catherine G. Lam

Prevention and Community Health Faculty Publications

Background: Retinoblastoma, the most common intraocular tumor globally, represents a curable cancer when diagnosed early and treated promptly. Delay to diagnosis, lag time prior to treatment initiation, and abandonment of treatment including upfront treatment refusal, represent stark causes of high retinoblastoma mortality rates in low- and middle- income settings, particularly regions in Africa. While a health delivery-based approach has been a historic focus of retinoblastoma treatments globally and is essential to quality care, this is necessary but not adequate. Retinoblastoma is a compelling disease model to illustrate the potential insights afforded in theory-informed approaches to improve outcomes that integrate public …

NYMC Faculty Publications

BACKGROUND: Adaptation to stress is critical for survival. The adrenal medulla, the major source of epinephrine, plays an important role in the development of the hyperadenergic state and increased risk for stress associated disorders, such as hypertension and myocardial infarction. The transcription factor Egr1 plays a central role in acute and repeated stress, however the complexity of the response suggests that other transcription factor pathways might be playing equally important roles during acute and repeated stress. Therefore, we sought to discover such factors by applying a systems approach. RESULTS: Using microarrays and network analysis we show here for the first …

Calcineurin And Glial Signaling: Neuroinflammation And Beyond, Jennifer L. Furman, Christopher M. Norris Sep 2014

Calcineurin And Glial Signaling: Neuroinflammation And Beyond, Jennifer L. Furman, Christopher M. Norris

Sanders-Brown Center on Aging Faculty Publications

Similar to peripheral immune/inflammatory cells, neuroglial cells appear to rely on calcineurin (CN) signaling pathways to regulate cytokine production and cellular activation. Several studies suggest that harmful immune/inflammatory responses may be the most impactful consequence of aberrant CN activity in glial cells. However, newly identified roles for CN in glutamate uptake, gap junction regulation, Ca2+ dyshomeostasis, and amyloid production suggest that CN's influence in glia may extend well beyond neuroinflammation. The following review will discuss the various actions of CN in glial cells, with particular emphasis on astrocytes, and consider the implications for neurologic dysfunction arising with aging, injury, …

Gene Expression Profiling Identifies Irf4-Associated Molecular Signatures In Hematological Malignancies, Ling Wang, Zhi Q. Yao, Jonathan P. Moorman, Yanji Xu, Shunbin Ning

ETSU Faculty Works

The lymphocyte-specific transcription factor Interferon (IFN) Regulatory Factor 4 (IRF4) is implicated in certain types of lymphoid and myeloid malignancies. However, the molecular mechanisms underlying its interactions with these malignancies are largely unknown. In this study, we have first profiled molecular signatures associated with IRF4 expression in associated cancers, by analyzing existing gene expression profiling datasets. Our results show that IRF4 is overexpressed in melanoma, in addition to previously reported contexts including leukemia, myeloma, and lymphoma, and that IRF4 is associated with a unique gene expression pattern in each context. A pool of important genes involved in B-cell development, oncogenesis, …

Size Dependent Translocation And Fetal Accumulation Of Gold Nanoparticles From Maternal Blood In The Rat., Manuela Semmler-Behnke, Jens Lipka, Alexander Wenk, Martin Schäffler, Furong Tian, Günter Schmid, Günter Oberdörster, Wolfgang G. Kreyling

Articles

Background

There is evidence that nanoparticles (NP) cross epithelial and endothelial body barriers. We hypothesized that gold (Au) NP, once in the blood circulation of pregnant rats, will cross the placental barrier during pregnancy size-dependently and accumulate in the fetal organism by 1. transcellular transport across the hemochorial placenta, 2. transcellular transport across amniotic membranes 3. transport through ~20 nm wide transtrophoblastic channels in a size dependent manner. The three AuNP sizes used to test this hypothesis are either well below, or of similar size or well above the diameters of the transtrophoblastic channels.

Methods

We intravenously injected monodisperse, negatively …
