Depression and anxiety symptoms after lower limb amputation: the rise and fall

Objective: To examine the time course of anxiety and depressive symptoms over a three year period after amputation. Design and settings: A prospective study in inpatients admitted to a rehabilitation ward after lower limb amputation. Subjects: Successive admissions over a one-year period of whom 68 were alive at follow-up, 2—3 years later. Interventions: Nil. Main measures: Hospital Anxiety and Depression Scale (HADS) on admission and discharge from inpatient rehabilitation and at a 2.7(SD=0.4) year mean follow-up period with correlation to demographic and patient features. Results: Of the 68 responding patients, 12 (17.6%) and 13 (19.1%) had symptoms of depression and anxiety respectively. This compared to an original incidence of 16 (23.5%) for both on admission and 2 (2.9%) on discharge. This rise in incidence from time of discharge was highly significant for both depression (P<0.001) and anxiety (P<0.001). Depression at follow-up was correlated to depressive symptoms at admission (P=0.03) and to having other significant comorbidities (P=0.02). Anxiety symptoms were commoner in younger patients (P=0.03). There was no association with age, gender, living in isolation, vascular cause for amputation, wearing a limb prosthesis or length of original inpatient stay. Conclusions: Depression and anxiety are common after lower limb amputation but resolve during inpatient rehabilitation. The incidence then rises again after discharge.

Industrial Waste Management with Application of RIAM Environmental Assessment: A Case Study on Toos Industrial State, Mashhad

Systematic industrial waste management is one of an important issue due to high environmental risks caused by improper waste disposal. Hence, present research was conducted to investigate environmental aspects of optimal disposal and management methods of industrial waste of Toos industrial estate in Mashhad. In this work, one of the environmental impact assessment methods called Rapid Impact Assessment Matrix (RIAM) was applied. Thus, various disposal options such as open dumping, sanitary landfill, gasification and incineration from the viewpoint of the physical, chemical, biological, ecological, cultural and social, economical and environmental aspects were evaluated. All of these aspects were compared due to selection of disposal methods through application of RIAM technique. The obtained results showed that sanitary landfill led to more beneficial effects than the other four mentioned options. Therefore, the best method of choice in compare to other options for waste management in the industrial estate of Toos, Mashhad was selected.
Interaction between vascular dysfunction and cardiac mass increases the risk of cardiovascular outcomes in essential hypertension.

AIMS To investigate the additive prognostic impact of both forearm endothelial dysfunction and left ventricular mass (LVM) for future cardiovascular events. METHODS AND RESULTS We enrolled 324 Caucasian, never treated, hypertensive outpatients. Endothelial function, by intra-arterial infusion of acetylcholine (ACh), and echocardiographic LVM were investigated. Patients were divided into tertiles on the basis of their increase in ACh-stimulated forearm blood flow (FBF) and LVM indexed by body surface area (LVMI). Cardiovascular events assessed were: fatal and non-fatal myocardial infarction, fatal and non-fatal stroke, transient cerebral ischaemic attack, unstable angina, coronary revascularization procedures, and symptomatic aorto-iliac occlusive disease. During a mean follow-up of 45.2+/-23.6 months, there were 47 new cardiovascular events (3.8 events/100 patient-years). The event rate was 6.8, 2.8, and 1.6% in the tertiles of ACh-stimulated FBF (log-rank test, P=0.0009), and 1.4, 3.4, and 6.6% in the tertiles of LVMI (log-rank test, P=0.0002), respectively. Besides, a significant interaction was documented between FBF and LVMI. In fact, the cardiovascular risk increases up to 11.4% in patients with low FBF and high LVMI. CONCLUSION For the first time, we demonstrate that the co-existence of LVH and endothelial dysfunction in hypertensive patients increases significantly the risk of subsequent cardiovascular events.
How to Grow Revenues in an uncertain World?

It was Friday afternoon and Rob Hammond, product executive for enterprise products at Syniverse, was sitting at his desk reviewing the draft board presentation that would be delivered next week. The first section of the draft presentation described the current enterprise SMS market--Hyper Competitive; the next section reviewed the company’s positioning--Vulnerable to Commodization; and the final section was blank, titled--Product Investments: Development Prioritization and Sales Training. Should Rob invest in sales efforts to promote Syniverse’ new value added enterprise product, or instead leverage Syniverse’ past success to pursue high growth emerging markets--like India, Southeast Asia, Latin America, and Greater China? These markets continued to grow rapidly and remained robust growth prospects for at least the next five years. To make an impact in the coming fiscal year, Rob had to focus organization efforts now in order to align the product development plans with sales training and distribution.
Ad hoc networks with smart antennas using IEEE 802.11-based protocols

Smart antennas have been studied extensively for use in cellular radio base station applications. Recently however, low cost array technologies have suggested that adaptive antennas may soon be cost effective for mobile ad hoc networks. In this paper we consider the potential use of adaptive antenna arrays in networks using protocols based on the IEEE 802.11 distributed coordination function (DCF). In the system under study, omnidirectional RTS/CTS exchanges are used to initiate array-mode data packet transmissions. Several variations on the basic protocol are considered. When two stations communicate using their antenna arrays, the ensuing gain across the link can be very large. In many cases the transmit power can be significantly reduced while still maintaining a sufficient link margin. We show that this reduction in power is a key factor in improving the capacity of an ad hoc network. Results are presented for various parameters which show how the capacity of the system scales with the size of the system. Significant capacity improvements are possible compared with a network using conventional IEEE 802.11 protocols. In our simulations a relatively inexpensive circular antenna array configuration is used with a fairly modest number of elements.
Financial Health Indicators: An Analysis Of Financial Statement Information To Determine The Financial Health Of DOD Contractors

Abstract : Prior to awarding a contract, government contracting officers must be able to determine the financial health of prospective contractors. In fact, according to the Federal Acquisition Regulation (FAR) 9.104-1(a), the very first general requirement to being considered a responsible prospective contractor is to show adequate financial resources to perform the contract or the ability to obtain financing. The purpose of this research is to identify a financial assessment framework that could assist DOD contracting officers with determining the financial health of potential DOD contractors. This research study may help DOD contracting officers determine the financial health of potential contractors prior to awarding a contract. The findings of this study provide a recommended framework that a contracting officer could follow in order to assess the financial health of a prospective contractor. The framework includes a ratio analysis using selected ratios compiled by this study, as well as a comparative analysis using industry average driven data. The framework also incorporates horizontal and vertical analyses, as well as bankruptcy and fraud analyses. The financial assessment framework created in this study is a comprehensive financial health assessment tool that can be utilized by DOD contracting officers.
Can High-risk Older Drivers be Identified in a DMV Setting with a Brief Battery of Functional Tests?

Recent research has indicated that some laboratory measures of functional ability may discriminate between crash-involved and crash-free older adults. However, the ability of these tests to provide the same level of discriminability in a real-world setting such as a Department of Motor Vehicles remains to be established. Therefore, in conjunction with the Maryland Department of Motor Vehicles and the National Highway Traffic Safety Administration, a brief battery of tests was developed and evaluated. The battery contained a number of cognitive tests (e.g., UFOV subtest 2, the closure subtest of the Motor Free Visual Perception Test [MVPT], Trails A and B, etc.) and physical measures (e.g., Rapid Pace Walk, Head and Neck Rotation, etc.) that prior literature had indicated might be related to crash risk in older adults. Motor Vehicle Administration staff were trained to administer the test battery. Older adults (N=4,173, mean age =69 years) were approached by the staff after license renewal and asked to help evaluate the brief battery. Of the 4,173 older adults approached at the field sites, 2,112 individuals aged 55-96 years of age participated. The primary outcome of interest for this study was the occurrence of an at-fault Motor Vehicle Collision (MVC) following assessment. For members of this sample, the outcome period ranged from 2-3 years. Rate Ratios were determined for each functional variable based upon at-fault crashes adjusted for driving exposure over this period. Univariate analyses revealed that five variables (Age, Walk Time, MVPT, Trails A and UFOV) were significantly related to crash frequency. These significant variables overlapped with one another to a certain degree, indicating that impaired older drivers score poorly on multiple cognitive assessments. The UFOV subtest 2 appears to be the most strongly associated within this analysis (RR=3.78, p<.05). When each variable in the model was adjusted for every other variable, only UFOV (RR=2.41, p < .05) and Rapid Pace Walk (RR=1.96, p < .05) remained uniquely related to the frequency of state-reported, at-fault crashes. The role of such a screening battery in field settings such as a DMV will be discussed.
Influenza virus neuraminidase: Structure, antibodies, and inhibitors

The determination of the 3‐dimensional structure of the influenza virus neuraminidase in 1983 has served as a platform for understanding interactions between antibodies and protein antigens, for investigating antigenic variation in influenza viruses, and for devising new inhibitors of the enzyme. That work is reviewed here, together with more recent developments that have resulted in one of the inhibitors entering clinical trials as an anti‐influenza virus drug.
Adaptive Multichannel Dereverberation for Automatic Speech Recognition

Utilizing an adaptive multichannel technique to mitigate reverberation present in received audio signals, prior to providing corresponding audio data to one or more additional component(s), such as automatic speech recognition (ASR) components. Implementations disclosed herein are “adaptive”, in that they utilize a filter, in the reverberation mitigation, that is online, causal and varies depending on characteristics of the input. Implementations disclosed herein are “multichannel”, in that a corresponding audio signal is received from each of multiple audio transducers (also referred to herein as “microphones”) of a client device, and the multiple audio signals (e.g., frequency domain representations thereof) are utilized in updating of the filter—and dereverberation occurs for audio data corresponding to each of the audio signals (e.g., frequency domain representations thereof) prior to the audio data being provided to ASR component(s) and/or other component(s).
Importance of Strategic Social Media Marketing

Technological innovation has grown at an unprecedented rate over the past couple of decades, creating multiple opportunities for marketing in online settings. The proliferation of social media helps customers become more empowered and engaged in their brand interactions, while also providing them with new tools in their search, evaluation, choice and purchases of marketing offerings. Consequently, these developments are influencing marketing practices, both strategically, and tactically. Nowadays, social media has developed in an essential part of marketing strategy for its ability to generate co-created value, to interactively connect brands to consumers, to monitor brand-related discussions and sentiments, to guide consumers in the decision-making process, to instigate customer-to-customer interactions, and transform consumers into brand advocates. The purpose of this paper is to examine the strategic opportunities of social media marketing for organizations. By providing a comprehensive conceptualization and definition of social media marketing, this research outlines its role in advertising, Customer Relationship Management, and e-Word-of-Mouth.

On communication, humanism, and the brief encounter.

The worlds of emergency medicine and critical care have evolved at a remarkable pace over the past few decades. Advances in the treatment of acutely ill and injured children have led to improved survival rates and overall outcomes in many cases. Yet as science and technology have moved forward, the progress of patient-centered care seems to have been somewhat left behind. A recent study of physician-patient encounters in an academic emergency department (ED) provides credible evidence of an overwhelming problem: the encounters are often brief and fail to include key health information [1]. The pediatric literature offers a similarly unsettling view of this problem. Recent data from a study of common medical terms used during encounters in a pediatric ED substantiate a wide gap in communication between ED physicians and their patients [2]. Though issues of physician-patient communication permeate many areas of medicine, the obstacles to effective physician-patient interactions are magnified in the ED setting: with lack of privacy, noise, frequent interruptions, expectation of rapid patient turnover, long waiting times, physical factors, and lack of an established relationship, the emergency department setting presents unique challenges to effective communication (p. 262) [1]. These barriers should not hinder the care of acutely ill and injured children. In the words of an ED physician, our patients are looking not only for our knowledge and skills, but also for the personal touch and compassion (p. 364) [3]. Despite the constraints of the ED setting, it is still possible for effective and gratifying physician-patient interactions to occur. An increased awareness of the need for more effective communication and humanism in the ED setting is a vital step towards achieving true change in the overall experiences of our patients and their families.
The origin and formation of clay minerals in soils " past , present and future perspectives

It has long been recognized that the minerals in the clay (<2 gm) fractions of soils play a crucial role in determining their major physical and chemical properties, and inevitably, questions concerning the origin and formation of these minerals have assumed some prominence in soil science research. This review considers some important aspects of these questions and is confined to clay minerals in soils as they are generally understood, that is as a medium for plant growth. The occurrence of clay minerals in saprolites or weathered rock is not discussed to any great extent because many studies have shown that saprolites are characterized by physicochemical conditions that are different to those in soils. Intimate grain-tograin contacts promote a special chemical environment on a local scale, bringing about the formation of transient clay mineral phases which quickly disappear in the overlying soil. For the purposes of this review the perspective of the past will be taken to be that of the early 1960s, which is a convenient historical benchmark in that it represents a time when the overall structural characteristics of the layer silicate clay minerals were to a large extent known, even though much detail remained to be filled in, as well as a time that immediately pre-dated the widespread utilization in soil science of analytical techniques such as scanning electron microscopy, electron probe microanalysis, M6ssbauer spectroscopy, electron spin resonance spectroscopy and infrared spectroscopy. This review will therefore attempt to summarize the general conclusions that had been arrived at regarding the origin and formation of certain clay minerals in soils in the early 1960s, the developments since that time and the situation as it currently stands, and to consider the outstanding problems to be addressed in the future. In this context, particular attention will be paid to micas, vermiculites, smectites, chlorites, intcrstratified minerals and kaolin minerals. As in all such reviews, a certain amount of subjectivity and personal preference is perhaps inevitable. P A S T P E R S P E C T I V E S The reviews of Millot (1965) and Jackson (1964) represent a convenient starting point with regard to the origin and formation of soil clays as assessed principally by the X-ray diffraction and microscopic 9 1999 The Mineralogical Society
Broad phenotypic variability in a single pedigree with a novel 1410delC mutation in the PST domain of the PAX6 gene

The PAX6 mutation present in an individual with aniridia was determined and phenotypic features of immediate relatives carrying the same mutation investigated. Mutation analysis revealed a novel single base deletion 1410delC in the PAX6 gene in ten affected individuals. Clinical features ranged from total aniridia to very mild anterior segment findings. Other findings included partial aniridia, iris stromal hypoplasia, keratitis, cataract, glaucoma, optic disc anomalies and foveal hypoplasia. It appears that independent modifying factors may underlie the variability of the different phenotypic features of the PAX6 mutation. © 2002 Wiley‐Liss, Inc.

A unique perspective on the demand for livestock product attributes

Byrd, Elizabeth S. Ph.D., Purdue University, December 2016. A Unique Perspective on the Demand for Livestock Product Attributes. Major Professor: Nicole J. Olynk Widmar. Consumers are increasingly concerned about the social and environmental impacts of the foods they purchase. Both choice experiments and best-worst scaling (BWS) methodology have been used to elicit consumer willingness to pay (WTP) for food attributes and the relative importance of food attributes to consumers. The dissertation consists of four essays. Chapter 2 presents a formal law review article exploring the laws associated with wild game harvest, consumption, and inspections. The remaining three essays (Chapters 3-5) each address an extension or application of choice experiment and/or BWS methodology focused on credence attributes of meat products. Two online surveys were used to collect choice experiment and best-worst data. Two different presentations of a BWS question were implemented. The two presentations yielded statistically different preference shares and rankings of attributes. Next, consumer WTP for local pork chops and chicken breasts was explored. Interestingly, consumers were willing to pay additional amounts for “local” chicken breasts but were unwilling to pay more “local” pork chops. Finally, the results of both BWS and choice experiments between a sample of outdoor enthusiasts and a nationally representative sample were
