Role of uterine and umbilical artery doppler assessment of the uteroplacental circulation in predicting pre-eclampsia: comparison between different doppler parameters

Background: Hypertensive disorders are the common cause of maternal death which affecting nearly 5-10% of pregnancies all over the world. Pre-eclampsia develop from inadequate trophoblast invasion of the maternal spiral arteries and Doppler values permits non-invasive evaluation of uteroplacental circulation and is of great importance in the management of high risk pregnancies. The aim of the study was to assess the findings of Doppler data in predicting pre-eclampsia and comparison of the efficacy of uterine artery Doppler and umbilical artery Doppler.Methods: The study comprises of 100 women with high risk pregnancy attending antenatal clinic at Geetanjali Medical College and Hospital, Udaipur were subjected to uterine and umbilical artery Doppler Study. Women with high risk pregnancy between 26-32 weeks of gestation were studied with colour Doppler. This was a prospective study over a period of 1 year from 2015-2016.Results: The results of the study revealed that 5 out of 100 participants developed pre-eclampsia. Out of different parameters, notch is the best predictor of pre-eclampsia with high sensitivity and highest PPV for uterine artery Doppler and S/D ratio is considered to be best indicator for umbilical artery Doppler. Regarding efficacy, umbilical artery Doppler is more predictive than uterine Doppler.Conclusions: Doppler study can be used for the prediction of pre-eclampsia to reduce maternal morbidity and mortality

The value of colour doppler assessment of the uteroplacental circulation in predicting intrauterine growth restriction

Background: Intrauterine growth restriction is a complication that arises due to decrease in uteroplacental blood flow during pregnancy. This decrease is associated with a pathological condition of spiral arteries thought to arise during placentation in first trimester of pregnancy. Thus, it might be possible to predict the development of these conditions by assessing uteroplacental blood flow in pregnancy with colour Doppler. The aim of the study was to assess the findings of Doppler data in predicting IUGR and finding the best predictors of IUGR in uterine and umbilical artery Doppler.Methods: In this prospective study, total of 100 women with high risk pregnancy attending Department of Obstetrics and Gynecology at Geetanjali Medical College and Hospital, Udaipur were subjected to uterine and umbilical artery Doppler Study. Women with high risk pregnancy between 26-32 weeks of gestation were studied with colour Doppler. This study was carried over a period of 1 year from 2015-2016.Results: Out of total 100 patients, 8 were found to have IUGR. Out of different parameters, Notch is the best indicator with high sensitivity and highest positive predictive value (PPV) of 50% followed by combination of parameter as it had the highest sensitivity of 62.5% for uterine artery Doppler. S/D Ratio is the best indicator with high sensitivity and highest positive predictive value (PPV) of 25% and 40% respectively followed by RI with highest sensitivity of 42.86% for umbilical artery Doppler.Conclusions: Value of Doppler assessment of uteroplacental circulation in predicting IUGR and is very useful in improving pregnancy outcome

"A Study For prediction of Water Quality of Non-Reserved Ponds of Bhilai-Durg Regions for Various Purpose"

Water supports life on earth and around which the entire fabric of life is woven. Ponds, as sources of water, are of fundamental importance to man. However pond may have been natural water sources exploited by man at different time to meet different needs or may have been created for a multitude of different purposes. The increased demand for water as a consequence of population growth, agriculture and industrial development has usurped environmentalists to determine the chemical, physical and biological characteristics of natural water resources. In present study the physicochemical (taste, odor, color, pH, temperature, electrical conductivity, alkalinity, total dissolved solids, chemical oxygen demand, biological oxygen demand, chloride, total hardness, calcium, magnesium) and microbial parameters of collecting sample from non-reserved ponds water samples. Studies of physiological parameters were done by APHA standard methods (1975) and microbiological analysis were done by isolation of bacteria through serial dilution of water samples than collected isolates were identified by morphological studies and biochemical tests. Results of physiochemical parameters were compared with limits prescribed by WHO standard (1984) and analyzedhigher than the give standard value of the WHO whereas dissolved oxygen for both ponds, chloride and total hardness for NR1pond were under range of standard value of WHO. Studies of microbial flora of non-reserved ponds were observed NR1-five and NR2-four colonies. The Morphological characteristics of the isolates obtained completed coliform test showed a positively completely confirmed test for all the water samples. The Biochemical characteristics of the isolates obtained from these water samples were shown some specific test for Salmonella Typhii (Salmonella agar), S. aureus (Enrich media) and coli form (MPN, EMB agar) were performed given positive results. The isolated bacteria species were identified to with reference to Bergey's Manual of Determinative Bacteriology (Buchanan and Gibbon, 1974).These identified isolates include Staphylococcus aureus,Salmonella species, Escherchia coli, Pseudomonasaerugionosa, Bacillus species, Proteus species, Klebsiellaspecies. In this present investigation it was found that the maximum parameters were exceed at the level of pollution except few parameters. So both ponds water not satisfy the requirement for the use in various purposes like domestic, agricultural, industrial etc. But the study of nonresrved pond water indicated that the community ponds are highly polluted and unsafe for human use

Benchmark criticality calculations for one speed neutron transport

The entire dissertation/thesis text is included in the research.pdf file; the official abstract appears in the short.pdf file (which also appears in the research.pdf); a non-technical general description, or public abstract, appears in the public.pdf file.Title from title screen of research.pdf file (viewed on October 17, 2007)Vita.Thesis (Ph. D.) University of Missouri-Columbia 2007.[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Benchmark criticality calculations for the two canonical problems of a critical slab and a sphere with isotropic scattering have been carried out using three different computational techniques. These approaches include the X-function and Neumann iteration, F[N subscript] method, and discrete ordinate methods. It is found that to the orders of the approximations considered here, the critical half thickness and critical radius values obtained through the three approaches are consistently accurate from 9 to 12 significant figures, and agree amongst themselves. The accuracy for the corresponding values for neutron density using X-function, and discrete ordinate method (the only two explored for the density computations) is 9 to 10 figures. In several instances, the results constitute an improvement on the previously reported benchmark results in literature. Our computational techniques have yielded highly accurate benchmark results for the critical half thickness of the slab and the critical radius of a sphere and also for neutron density. These results could be used as new benchmark values for future criticality analysis. In addition to the calculations described above, the standard Monte Carlo code, (MCNP5) has been verified against our results for the case of a critical sphere. Converged keff [eff is subscripted] and neutron density values using MCNP5 are compared with our suggested benchmark values from DO method. It is found that the neutron density values obtained by MCNP5 show a significant deviation from our suggested benchmark values using the above three methods at lower c values (or for larger spheres).Includes bibliographical reference

Series Compensated Transmission Line Protection based on Mutual Impedance Scheme

In conventional distance protection scheme, positive sequence impedance is used to protect a transmission line against short circuit faults. The presence of series compensation increases the load-ability of transmission line and it helps in improving the power system stability. It provides a better voltage profile along the transmission line. The presence of series compensator in the fault path affects reach and directionality of distance relays. Due to the presence of series-compensation, the positive-sequence impedance of the fault path is affected, due to this the distance relay mal-operate. In order to overcome this drawback of distance relay, the concept of mutual impedance-based relaying is proposed as a new protection scheme. Since mutual impedance does not get affected by presence of seriescompensation.In this study, mutual impedance-based distance protection scheme is presented for series-compensated transmission lines. The values of current and voltage at both the ends of the line are used for computing the mutual impedance between the relay and fault point. The proposed scheme can protect the line against single line to ground and double line to ground faults. The protection scheme gives reliable results when it is tested against single- line-to-ground faults and double-line-to-ground faults. The performance of the proposed scheme is studied by computer simulations using MATLAB and its results are compared with conventional distance protection scheme

The objective of this work is to propose and design a pregnancy care network for pregnant women and healthcare providers. The network model, an eHealth application based on smartphone-based devices and communication systems, is designed to strengthen communication links between health professionals and pregnant women and increase education, awareness and quality of care during pregnancy and childbirth

The Use of Networking in Nursing Practice —An Integrative Review

Networking provides access to countless opportunities for nurses and patients and allows them to communicate, interact and collaborate with each other in order to enhance nursing care practice and improve health. The ubiquity of information and communication technologies have the potential to improve access to both health information and services in health care. The authors aim for this study is to investigate the role of networking tools in shaping and improving nursing care practices. An integrative review was conducted and electronic databases of PubMed, Cochrane, Science Direct and ACM Digital Library were searched for studies published between 1985 and 2015. Sixteen articles, based on the use of networking tools in nursing care practice, were included in the review. Data synthesis consists of writing descriptive summaries and thematic analysis of the key findings in the included articles. Different networking tools are currently used by nursing professionals for patient’s safety and well-being. These include information technology, telehealth nursing, IT and networking applications, social media networks, miscellaneous interaction networks, internet as a source of information and communication networks. Networking assist healthcare professionals with completing their daily tasks such as teaching patients, monitoring their health, tracking their blood pressure and much more. A variety of networking tools are available for managing chronic disease, diet, and lifestyle choices of patients. However, privacy, security and reliability of exchanged information is extremely important in improving the quality of patient care

Women’s Views on Handling and Managing Their Breast Cancer in Pakistan: A Qualitative Study

In this study, we examine and analyze the experiences of women and their perceptions on handling and managing their breast cancer. Seven women from Peshawar, Pakistan who had breast cancer and have been cured, were interviewed. Qualitative content analysis of their life stories was performed using a computerized software Atlas.ti. In the coding process, 128 codes were initially developed. These codes were then grouped into 12 categories, which were then further refined into 8 theoretically grounded categories: awareness and education about breast cancer, cultural barriers, early detection, quality of care and treatment, support, side effects, courage and learned to face challenges. The early views of participant’s feelings about breast cancer are mostly similar to the general population in Pakistan. Before starting treatment, all participant were unaware of the treatment process and had fear in their mind. They were hesitant in starting their treatment and were worried. However, when they were cured, their attitudes toward breast cancer and even to their whole lives were changed. Comprehensive awareness programs in a culturally acceptable language and facilities for routine breast examinations should be easily accessible to all women in Pakistan in order to promote early detection. In order to eradicate cultural barriers, female staff who are trained to perform routine breast examinations, should be available in all facilities and treatment centers
