W. Alan C. Mutch,Randall R. Fransoo,Barry I. Campbell,Dan G. Chateau,Monica Sirski,R. Keith Warrian
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0017457
Abstract: We compared the proportion of ischemic heart disease (IHD) patients newly diagnosed with dementia and depression across three treatment groups: percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG) and medical management alone (IHD-medical).
Correspondence Analysis on a Space-Time Data Set for Multiple Environmental Variables  [PDF]
Palma Monica
International Journal of Geosciences (IJG) , 2015, DOI: 10.4236/ijg.2015.610090
Abstract: Applications of the multivariate technique called correspondence analysis for environmental studies are relatively new and are limited to spatial multivariate data set. In this paper, a procedure of applying correspondence analysis to a large space-time data set for multiple environmental variables is shown. In particular, nitrogen dioxide and carbon monoxide hourly concentrations measured during January 1999 at several monitored stations in a district of Northern Italy are analyzed. The procedure consists in transforming the continuous variables into categorical ones by the means of appropriate indicator variables, generating special contingency tables and applying correspondence analysis. The use of this classical multivariate technique allows the identification of important relationships among pollution levels and monitoring stations and/or relationships among pollution levels and observation times.
Effect of Pixellization on Efficiency and Stability of MEH-PPV Based Polymer Light-Emitting Diodes  [PDF]
Ranbir Singh, Monica Katiyar
Journal of Encapsulation and Adsorption Sciences (JEAS) , 2012, DOI: 10.4236/jeas.2012.21002
Abstract: Organic light-emitting diodes are generally depicted as sequential deposition of active layers and electrodes onto a substrate, but commercial devices are fabricated using pixellization technique, where an insulator layer is introduced between the indium tin oxide and organic layer to define the area of the active device. Here, we have inserted a layer of photoresist (thickness ~ 200 nm) at the edge of patterned anode (indium tin oxide) and between the anode and hole transport layer (Poly 3, 4-ethylenedioxythiophene poly styrenesulfonate) to examine its effect on the leakage current of organic light-emitting diode and on the electron-hole recombination ratio in the emission area, as a result increasing the luminance efficiency. Current leakage causes the loss of charges, which adversely affects the recombination of electrons and holes in the emitting zone and results in poorer luminance efficiency. In this paper, we report the effect of pixellization on current density-voltage, luminescence-voltage and degradation behavior of single layer Poly[2-methoxy-5-(2’-ethylhexyloxy)-1, phenylene vinylene] based organic light-emitting diodes. Devices with isolation layer have 30% higher external electroluminescence quantum efficiency and reduced device degradation in comparison to without isolation layer.
Critical Factors in Managing Relationally Demanding Jobs, in Care for Very Ill and/or Dying Patients: A Phenomenological Study among Public Hospital Nurses  [PDF]
Asgerdur Bjarnadottir, Monica Lillefjell
Open Journal of Nursing (OJN) , 2015, DOI: 10.4236/ojn.2015.51007
Abstract: Background: Workload, interpersonal relationships, professional conflict and the emotional cost of providing care are potential sources of stress and burnout among nurses. Based on experiences of hospital nurses, this paper aims to identify critical factors for nurses in managing relationally demanding situations in care for very ill and/or dying patients. Methods: In-depth interviews were carried out with six nurses, working in a medium-sized hospital in Norway. The interviews were analysed using an interpretative phenomenological analysis. Results: The lack of identification with the core aspect of the job, relational contact with patients and relatives, and external motivation were found as potential barriers for managing relationally demanding jobs. The results also indicate that the nurses’ experiences of symptoms of burnout can be a result of demands that exceeded the nurses’ resources. A match between personal capacity and demands, mutual support among colleagues and leadership support, and contextual factors are critical to prevent the negative process of burnout. Conclusion: The results underscore the importance of an early response to employees who are beginning to struggle at work and the relevance of a true match between personal capacity and job demands. Moreover support among colleagues and leadership seems critical to prevent a negative process of burnout and help to manage relationally demanding jobs.
Thin Film Encapsulation at Low Temperature Using Combination of Inorganic Dyad Layers and Spray Coated Organic Layer  [PDF]
Sandeep Kumar, Monica Katiyar
Journal of Encapsulation and Adsorption Sciences (JEAS) , 2017, DOI: 10.4236/jeas.2017.74011
Abstract: Organic devices have many advantages such as low material consumption and low energy requirements, but they have serious issues regarding long term stability. Hence we need to develop a barrier film which solves this problem. Initially, the organic devices were fabricated on glass and were encapsulated using glass and epoxy (as sealant). Gradually there was a need to shift on to flexible substrates which required encapsulation to be flexible as well. Therefore, the motivation of the work is to develop thin film encapsulation that can be made flexible. The low temperature PECVD grown films of SiOx and SiNxwere used as the barrier film. Alternate inorganic layers (2-dyads) provided barrier of ~10-2 g/m2 day and increasing the number of dyads to five improved the water vapor transmission rate (WVTR) only by one order of magnitude. However, introducing organic layers in this structure resulted in WVTR value of order 10-5 g/m2 day. The organic layers were deposited by spray technique.
Drug-Induced Hemolytic Anemia: A Fatal Complication Further Under-Recognized in Sickle Cell Disease  [PDF]
Monica Khurana, Shekhar S. Raj
Open Journal of Blood Diseases (OJBD) , 2017, DOI: 10.4236/ojbd.2017.73008
Abstract:
Drug-induced immune hemolytic anemia (DIIHA) is commonly attributed to cephalosporins. Ceftriaxone is the most frequently administered cephalosporin in patients with sickle cell disease. We present a pediatric patient with severe DIIHA (hemoglobin < 2 g/dl) who survived. Since DIIHA often goes undiagnosed until late in the course, vigilance of DIIHA minimizes unnecessary diagnostic tests and therapies. DIIHA likely remains under-recognized in all patient subpopulations due to its rarity and overlapping presentations with other conditions. Distinction between exacerbation of chronic hemolysis and new onset of acute hemolysis poses a unique challenge in patients with sickle cell disease. A thorough analysis is warranted to better identify factors within the pediatric sickle cell population that may increase the predisposition for DIIHA, particularly due to ceftriaxone.
Master’s Degree, a New Requirement to Become an RDN by 2024: A Comparison of Nutrition Graduate Programs Offered in the USA  [PDF]
Monica Sanchez, Deanna L. Pucciarelli
Food and Nutrition Sciences (FNS) , 2019, DOI: 10.4236/fns.2019.101001
Abstract: Background: The registered dietetic four-year degree educational structure has been intact since 1926. Master level nutrition programs exist in the U.S., but are not standardized or accredited unlike four-year degrees. Academic requirements for nutrition graduate programs vary regionally across the nation. Objective: To 1) quantify and describe the availability of Master level nutrition programs regionally; and 2) examine the current M.A. and M.S. program requirements for a nutrition graduate degree in the U.S. Methods: Nutrition graduate programs (n = 201) were analyzed and compared by geographical region. Data were collected between August 2017 and May 2018. Inclusion criteria were defined as: nutrition graduate programs listed in the American Society of Nutrition (ASN) database that had a nutrition graduate program website. Descriptive statistical analysis measured evaluated variables. Results: A total of 201 nutrition graduate programs in the U.S. were identified. The title of the programs was categorized into 29 main themes. The most common nutrition graduate program title was a M.S. in Nutrition, 55 institutions (27.4%). A total of 181 institutions offered a M.S. with a required thesis, whereas 95 offered a M.S. with a non-thesis option, and only eight offered a M.A. Region 3-South offered the highest number of nutrition graduate programs (66), followed by region 2-Midwest with 49 programs, region 1-Northeast offered a total of 46 programs, and 37 programs were offered in region 4-West. Conclusion: In 2024, as part of the RD eligibility criteria, it will be required that students possess a master’s degree. To date, only one master’s program in the U.S. is accredited, which assures the student a measure of confidence of program rigor and accountability. Dietitians’ three major professional concerns: respect, recognition and rewards are predicated on rigorous educational programs that meet ACEND standards. It is unlikely that all U.S. master level programs will be accredited by 2024.
A Bayesian Abstract Economy with a Measure Space of Agents
Monica Patriche
Abstract and Applied Analysis , 2009, DOI: 10.1155/2009/523619
Abstract: We define the model of an abstract economy with differential (asymmetric) information and a measure space of agents. We generalize N. C. Yannelis's result (2007), considering that each agent is characterised by a random preference correspondence instead of having a random utility function. We establish two different equilibrium existence results.
Decision making in local therapy for breast cancer
Monica Morrow
Breast Cancer Research , 2007, DOI: 10.1186/bcr1806
Abstract: The mean patient age was 60 years and 70% were white. Less than a high school level of education was reported by 27%; 61% graduated from high school or had some college education, and 13% were college graduates. The mastectomy rate was 30% for patients with both DCIS and invasive cancer. Accepted clinical contraindications to breast-conserving surgery were reported by 11.5% of the study population. In 41% of cases the patient reported that she was the primary decision maker, the decision was shared in 37%, and was made by the surgeon in 22% of cases. The therapy recommended by the surgeon was breast-conserving surgery in 49%, mastectomy in 15%, and patients reported being offered a choice between the two procedures in 37% of cases. Greater patient involvement in the decision-making process was significantly correlated with treatment by mastectomy after adjustment for multiple clinical and demographic variables. Only 5.8% of women whose surgeon made the treatment decision had a mastectomy, as compared with 16.8% who reported a shared decision and 27% of women who reported that they made the decision (P = 0.003).Concern about disease recurrence was the most influential factor in treatment choice, with 40% of women reporting that their treatment choice was greatly influenced by this concern. Concerns about disease recurrence were strongly associated with receipt of mastectomy; 52% of women who were greatly concerned about disease recurrence received a mastectomy, as compared with 19% of those who were not influenced, or only slightly influenced, by this concern (P < 0.001) [1].Patients expressed a high level of confidence in decision making, with more than 80% of women of all ages being very or extremely confident about their treatment choice. However, fewer than 50% were able to answer correctly a true-false question about the lack of a survival difference after treatment by mastectomy or lumpectomy and radiation.We also examined the match between decision control and
Personalized surgical treatment of breast cancer
Monica Morrow
Breast Cancer Research , 2007, DOI: 10.1186/bcr1810
Abstract: During the past decade, substantial strides have been made in the application of personalized surgical therapy, with the majority of women now being offered a choice between mastectomy alone, mastectomy with immediate reconstruction, or breast-conserving therapy (BCT), consisting of lumpectomy and radiation. Multiple prospective randomized trials have shown no difference in survival between patients treated with BCT and those undergoing mastectomy, even after long-term follow up. Selection criteria for BCT have been defined [1] and are related to the extent of disease within the breast and the ability to administer radiotherapy safely. Contraindications to BCT are as follows: first and second trimester of pregnancy; inability to achieve negative margins of resection; multicentric cancer; diffuse suspicious or indeterminate microcalcifications; and history of prior irradiation to breast region. Interestingly, biological factors such as hormone receptor status, HER2 over-expression, tumour grade and other histological features, and node status are not useful criteria for identifying women best treated by mastectomy. Adhering to the BCT contraindications given above, local control rates of greater than 90% at 10 years are now obtained in patients receiving adjuvant systemic therapy [2].The use of gene profiles to predict the risk for systemic recurrence [3] has raised interest in the role of these profiles in identifying patients at high risk for local recurrence when treated with BCT. Mamounas and coworkers [4] examined the ability of the 21-gene recurrence score (Oncotype Dx?; Genomic Health Inc., Redwood City, CA, USA) to identify groups of women with different risks for locoregional recurrence (LRR). The 21-gene recurrence score has been shown to be both prognostic and predictive of the benefit of adding chemotherapy to tamoxifen. In a retrospective study using material from National Surgical Adjuvant Breast and Bowel Project (NSABP) treatment trials, statistically
