The magnitude of Asthma COPD Overlap Syndrome (ACOS) among patients diagnosed as Asthma and COPD: A single center cross-sectional study

BACKGROUND: Differentiating Asthma with fixed airway from COPD is hard, due to similar symptom profile. Our attempts to understand the pathogenesis of these diseases started with Dutch hypothesis, which considers both Asthma/COPD as same spectrum, unlike the British hypothesis where Asthma and COPD are considered unique with no similarity. However, 'ACOS' Asthma COPD overlap Syndrome is even complicated. It has both Asthma, COPD features. ACOS has higher morbidity, more economic burden and poorer QOL recent studies say. METHODS: A prospective observational study done among diagnosed cases of Asthma and COPD in Pulmonary OPD review patients (> 6 months). Possible subjects were short listed prior to OPD. 60% patients were selected by simple randomization. Questionnaire was filled, X ray, spirometry, 6 MWT and other relevant investigations were reviewed. SPSS software was used for data analysis. RESULTS: Of 877 patients included in the study (M = 445, F = 432), 714 were diagnosed as Asthma, 156 as COPD and 7 patients as ACOS. Using the GINA Tool, 48 (5.4%) were truly ACOS. Of all asthma patients, 95.5% truly had asthma, 2.8% of them had ACOS and 1.7% had COPD. Of all COPD patients, 58% were truly COPD, 17.2% was ACOS and 24.8% was asthma. ACOS patients had more recurrent exacerbations than Asthma/COPD patients. ACOS had more exacerbations, admissions and NIV use than asthma but lesser than COPD. CONCLUSION: ACOS is widely prevalent in India as well. Gina tool is a wonderful instrument to differentiate Asthma, COPD and ACOS.
Antioxidant and Biological Activities of Three Morphotypes of Murraya koenigii L. from Uttarakhand

The antioxidant activities of three morphotypes of Murraya koenigii L were evaluated by ABTS and phosphomolybdenum assays along with plant polyphenolic constituents and reference antioxidants. All examined methanolic extracts showed significant activity to scavenge ABTS and hydroxyl free radicals, reducing power, iron chelating ability and total antioxidant capacity in the order: Brown>Dwarf>Regular. Total polyphenol content (111-532 mg/g), flavonoid (0.01-0.09%) contents in dried plant samples was determined spectrophotometrically. The present study indicates the value of Murraya koenigii L as good source of antioxidants especially brown type.

UWB Pulse Propagation into Layered Model of Human Body

The biomedical applications of Ultra-Wide Band (UWB) radar system promise a very important means to remotely monitor physiological signal. Researchers have shown great interest in proposing analytical techniques to accurately predict the propagation of UWB pulse in tissues layers. This paper focuses the study of the propagation of a UWB pulse into a human body to characterize the absorption and reflection of UWB signal due to different layers. Several time behaviors for the reflected pulse were used and compared with the transmitted pulse to the feasibility of movement and heartbeat activity monitoring. Results from the simulation showed that if the UWB transmit antenna is placed far from the human body, the reflection from the interface between the air and the fat can be used to detect the movements of the activity. Therefore, we proposed designing an analytic model of tissue layers, considering some parameters. Furthermore, the frequency dependency of the different layers, tissues dielectric properties and the continuous motion of intra thoracic tissue layers were incorporated. The present work illustrates an application of UWB system for contactless detection and analysis of the human vital signal. This paper focuses on the design of a propagation UWB pulse into a layered model of the human body using the tool of modeling Agilent Advanced Design System.
Recuperación de imágenes basadas en contenido mediante descriptores híbridos

The present work aims to analyze di erent existing image descriptors for contentbased image retrieval (CBIR) and combine in such a way as to obtain a hybrid descriptor that allows a better accuracy in feature extraction and automatic image grouping, than their predecessors. To achieve this it is studied, analyzed and evaluated the di erent color descriptors, texture and form to verify its usefulness in this work. Subsequently focused on the color descriptor CLD (Color Layout Descriptor) and the Tamura texture descriptor for feature extraction; for clustering was used classi er K-means partition and SOM (Self-Organizing Map) classi er, with a database of 1000 images grouped en 10 classes. The results showed a better performance against the metrics of precision and recall for Hybrid descriptor (CLD-Tamura) with K-means in the extraction, clustering and image retrieval by similarity. Finally, we can conclude that hybrids are more e ective descriptors in the feature extraction performance by increasing the recovery process by increasing the percentage of its precision and recall in the ruling class groups

Intelligent spectrum management techniques for wireless cognitive radio networks

This thesis addresses many of the unique spectrum management challenges in CR networks for the first time. These challenges have a vital effect on the network performance and are particularly difficult to solve due to the unique characteristics of CR networks. Specifically, this thesis proposes and investigates three intelligent spectrum management techniques for CR networks. The issues investigated in this thesis have a fundamental impact on the establishment, functionality and security of CR networks. First, an intelligent primary receiver-aware message exchange protocol for CR ad hoc networks is proposed. It considers the problem of alleviating the interference collision risk to primary user communication, explicitly to protect primary receivers that are not detected during spectrum sensing. The proposed protocol achieves a higher measure of safeguarding. A practical scenario is considered where no global network topology is known and no common control channel is assumed to exist. Second, a novel CR broadcast protocol (CRBP) to reliably disseminate the broadcast messages to all or most of the possible CR nodes in the network is proposed. The CRBP formulates the broadcast problem as a bipartite-graph problem. Thus, CRBP achieves a significant successful delivery ratio by connecting different local topologies, which is a unique feature in CR ad hoc networks. Finally, a new defence strategy to defend against spectrum sensing data falsification attacks in CR networks is proposed. In order to identify malicious users, the proposed scheme performs multiple verifications of sensory data with the assistance of trusted nodes.
Influencia de la edad como factor pronóstico en la decisión terapéutica y de supervivencia en el cáncer de mama

El aumento de la esperanza de vida en los paises desarrollados y la circunstancia de que casi la mitad de los canceres de mama suceden en las pacientes de 65 o mas anos, augura un incremento en la prevalencia de esta enfermedad en los proximos anos. A pesar de que los canceres de mama en las pacientes de > 70 anos suelen de histologia mas indolente, en su mayoria tumores hormonosensibles tipo luminal A, la mortalidad especifica de edad es alta. Entre los factores que pueden determinar el aumento de la mortalidad especifica de enfermedad se encuentran: una menor adherencia al tratamiento, incluyendo terapias poco toxicas como la hormonoterapia, la realizacion de un abordaje local menos radical, seleccion de terapias menos eficaces y toxicas, y el presentimiento de una mayor toxicidad en estas pacientes de las terapias estandar. La escasez de ensayos clinicos donde se incluyan este tipo de pacientes de edad avanzada hace que no se tenga informacion sobre la eficacia y la toxicidad real de los tratamientos en estas pacientes. OBJETIVOS: Se ha realizado un estudio retrospectivo de seguimiento ( cohortes ) de 2126 pacientes con cancer de mama desde el 1 de Enero del ano 2006 al 1 de Enero del ano 2011 obtenido en el registro de cancer de mama en el Hospital General Universitario Gregorio Maranon de Madrid. El objetivo es analizar la influencia de la edad en el pronostico, en la decision terapeutica y en la supervivencia de la enfermedad.
Distribution and Movements of Belugas, Delphinapterus leucas, in the Canadian High Arctic

Belugas, Delphinapterus leucas, move into the coastal waters of Somerset Island as soon as the annual land-fast ice breaks up in late June – early July. Six bays or inlets which receive the outflow of rivers are the major areas of summer aggregation. Belugas captured and equipped with satellite-linked UHF transmitters in Cunningham Inlet (Barrow Strait), Elwin Bay (Prince Regent Inlet), and Creswell Bay moved west into Peel Sound where they frequented two other estuaries. Rapid and directed movement out of Peel Sound occurred in late August. All of the animals which transmitted locations into September or October moved to eastern Devon Island and Jones Sound. The longest period of transmission was 75 d, lasting until mid-October. Belugas tagged in three different locations around Somerset Island in the summers of 1988–93 showed a well-defined and consistent pattern of behaviour. Aerial surveys done during this period confirm that the vast majority of belugas in this region are involved in these seasonal m.
Carbon balance of young birch trees grown in ambient and elevated atmospheric CO2 concentrations

We constructed a carbon budget for young birch trees grown in ambient and elevated CO2 concentrations over their fourth year of growth. The annual total of net leaf photosynthesis was 110% more in elevated CO2 than in ambient CO2. However, the trees in elevated CO2 grew only 59% more biomass than the trees in ambient CO2 over the year. Modelling studies showed that larger loss of carbon from fine‐root production and growth of the root‐associated mycorrhiza by the trees in elevated CO2 probably accounted for all the remaining difference in net photosynthesis between the two treatments. Our modelling also showed that the fraction of net photosynthate consumed by respiration of nonleaf tissue was similar in the two CO2 treatments, and was 26% and 24% for trees in ambient and elevated CO2, respectively.
Mechanical behaviour of corrugated laminates

The present research work intends to perform a wide set of structural analyses upon corrugated composite laminated panels and based on these analyses, to assess their mechanical response in correspondence to the constructive solutions, which may range from the composite materials selection to the geometrical features and other modelling parameters. To improve the mechanical performance of those panels one may consider enhancing their geometrical characteristics, their corrugation shape configuration and the materials used to build them. In this latter case, when considering materials selection, laminated composites may also constitute an important alternative. In any case it is considered necessary to assess the impact that each of these parameters may have in the static and in the free vibration behaviour of the structures, in a comprehensive and detailed way. To achieve the main objective of this research work, a comprehensive and diversified set of case studies is considered in order to characterize the influence that each of the modelling, material and geometrical parameters and characteristics may have in the mechanical response of a corrugated panel. This study allowed concluding that for the wide set of design parameters considered, the fibre orientation and corrugation parameters are the ones responsible for the majority of the significantly improved performances.
Homöopathie und evidenzbasierte Medizin

ZUSAMMENFASSUNG Das gesellschaftliche Interesse und die Diskussionen um die Homöopathie sind groß. Aber seit Erfindung der Homöopathie bleibt uns dieses Verfahren einen nachhaltigen und reproduzierbaren Nachweis einer Wirksamkeit schuldig. Es existiert keine hochwertige Evidenz, dass die Homöopathie bei irgendeinem Krankheitsbild über Kontexteffekte hinaus effektiv wäre. Die Homöopathie birgt darüber hinaus potenzielle direkte, indirekte und intangible Risiken.
Manipulation of the n -3 polyunsaturated fatty acid composition of avian eggs and meat

An imbalance in the human dietary intake of various types of fatty acids has become apparent. Results of fundamental studies have shown specific and beneficial effects on human health and well-being through the consumption of the long chain n-3 polyunsaturated fatty acids, in particular eicosapentaenoic acid and docosahexaenoic acid, which play an important role in rectifying this imbalance. As a result of these observations, recent recommendations pertaining to the consumption of dietary fat have stressed the importance of consuming higher levels of these fatty acids. In addition to increasing oily fish consumption, intake of the n-3 polyunsaturates can be enhanced through the consumption of commonly occurring non-fish foods containing elevated levels of these fatty acids. The fatty acid composition of the lipids of avian egg yolk and muscle tissues may be modified to match human nutritional guidelines better by appropriately manipulating the fatty acid composition of the diet; for example, modifications of the avian diet have raised total n-3 fatty acid content in egg yolk to over 200mg. Beneficial effects on blood lipoprotein characteristics in humans who consumed eggs with such modified fatty acid contents have been recorded. As in the case of eggs, meaningful quantities of n-3 polyunsaturates have been incorporated into major poultry muscle tissues. Concerns have been expressed over the development of unacceptable odours in eggs and meat from birds fed diets with increased polyunsaturation. However, by using only high quality materials, limiting the amount of fish oil or fishmeal within the diet and optimising the provision of supplemental dietary antioxidants, the production of eggs and meat with increased n-3 polyunsaturates is practicable.
Baseline hemoglobin and creatinine clearance as independent risk factors for 30-day event rate in patients of acute ST-elevation myocardial infarction undergoing primary percutaneous coronary intervention

Background: Primary percutaneous coronary intervention (PCI) is the most effective therapy for managing acute ST-segment elevation myocardial infarction (STEMI). Studies have shown baseline low hemoglobin (Hb) and reduced creatinine clearance (CrCl) as risk factors for adverse outcomes in patients with heart failure, in patients undergoing PCI, and in acute coronary syndrome. However, their similar role in patients of acute STEMI undergoing primary PCI is not known. Objective: The main objective is to study whether baseline Hb and CrCl are the independent risk factors for the 30 days event rate in patients of acute STEMI undergoing primary PCI. Methods: We prospectively studied 500 patients of acute STEMI undergoing primary PCI. Hb and CrCl were measured at baseline and then at 15th and 30th day after the event. Patients were divided into four groups based on whether they have normal or abnormal baseline Hb and CrCl. Patients were followed for 30-day postdischarge for incidence of major adverse events in the form of death, reinfarction, reintervention, and hemodynamically unstable ventricular tachyarrhythmias. We assessed correlation between baseline Hb, CrC, l and 30-day event rate among four groups using Chi-square test. Results: On comparison among groups, compared to Group 1, Group 2, 3, and 4 had significantly higher adverse events ([6.48% vs. 19.44%] [P = 0.021]), ([6.48% vs. 30%] [P = 0.0003]), ([6.48% vs. 51.66%] [P ≤ 0.0001]), respectively, at 30 days after primary PCI. Conclusion: In patients of acute STEMI undergoing primary PCI, both baseline impaired CrCl and low Hb behaved independently as risk factors for increased 30-day event rates.
Unusual Case of Stroke in Fracture Supracondylar Femur in Hypertensive AdultMale

Stroke is a major health problem in India. 80% strokes are ischemic strokes and remaining 20% are hemorrhagic. In hypertensive patient, cause of ischemic stroke is mostly due to atheroma formation in the arteries. Uncontrolled high blood pressure increases a person's stroke risk by four to six times. The risk of stroke is directly related to how high the blood pressure is. Stroke patients may have an increased risk of fractures because of weak bones or an increased risk of falling. Females, older age, low abbreviated mental test score and pre-stroke dependence are associated with an increased fracture rate. In animal model bone fracture increases alarmins and proinflammatory cytokines in the blood, and provokes macrophage infiltration and proinflammatory cytokine expression in the hippocampus. In murine experiment Bone fracture, shortly after stroke, enhances stroke-related injuries in brain by augmenting the neuro-inflammatory response. Many studies state cause of fractures after stroke but it is uncommon for ischemic stroke to occur after traumatic fracture. We present an uncommon occurrence of ischemic stroke on third day post traumatic fracture supracondylar femur in a 45-year-old known hypertensive patient.
Haemodynamics of Large Vessels by Phase Contrast MRI

The cardiovascular system is the network of blood vessels in the body with the major role in the transportation of oxygen and nutrition to the organs and the waste products from the organs. The diseases of the cardiovascular system, either acquired or congenital, may result in ischemia or undersupply of major organs, which is a threat to the overall health of an individual. Events caused by cardiovascular diseases are the leading cause of morbidity and mortality worldwide. Despite improvements in the treatment and the prevention strategies of cardiovascular diseases, the social and economic burdens due to these diseases continue to grow. Further efforts, therefore, are required to find underlying mechanisms of these diseases and to find effective risk predicting markers for prevention and treatment. This thesis focuses on two diseases which are examples of acquired and congenital cardiovascular diseases: carotid atherosclerosis and univentricular heart (repaired with Fontan operation).
Shrinkage, pretest and LASSO estimators in parametric and semiparametric linear models

The theory of pretest (Bancroft (1944)) and James-Stein(James and Stein (1961)) type shrinkage estimation has been quite well known for the last five decades though its application remains limited. In this dissertation, some contributions to different types of parametric and semiparametric linear models based on shrinkage and preliminary test estimation methods are made which improve on the maximum likelihood estimation method. The objective of this dissertation is to study the properties of improved estimators of the parameter of interest in parametric and semiparametric linear models and compare these estimators with the least absolute shrinkage and selection operator (Tibshirani (1996)) estimator. Chapter two contains a study of the properties of the shrinkage estimators of the parameters of interest in a Weibull regression model where the survival time may be subject to fixed censoring and the regression parameters are under linear restrictions. Asymptotic properties of the suggested estimators are established using the notion of asymptotic distributional risk. Bootstrapping procedures are used to develop confidence intervals. An extensive simulation study is conducted to assess the performance of the suggested estimators for moderate and large samples. In chapter three, we consider generalized linear models for binary and count data. Here, we propose James-Stein type shrinkage estimators, a pretest estimator and a Park and Hastie estimator. We demonstrate the relative performances of shrinkage and pretest estimators based on the asymptotic analysis of quadratic risk functions and it is found that the shrinkage estimators outperform the maximum likelihood estimator uniformly. On the other hand, the pretest estimator dominates the maximum likelihood estimator only in a small part of the parameter space, which is consistent with the theory. A Monte Carlo simulation study has been conducted to compare shrinkage, pretest and Park and Hastie type estimators with respect to the maximum
Who deserves a chance? Identifying talent that might otherwise be lost in university admissions processes

The ENTER represents an efficient, cost-effective way of selecting school leavers for admission to university courses. Nonetheless, there are many reasons why a student’s true potential may not be represented by a single summary score of achievement. The philosophy underlying the development of a selection instrument for students seeking admission to alternative entry programs is outlined. Dispositional characteristics such as confidence to achieve in an academic setting, ability to enact strategies for success, and enjoyment of cognitively challenging tasks should survive in spite of negative academic outcomes like a lower than expected ENTER score. The utility of measuring these is discussed. Preliminary findings relating to these variables are compared to results reported in the literature for students selected through normal competitive processes. The instrument has yet to be validated, but more appropriate selection procedures for students who have talent but who would otherwise be lost to the system are justified.
