Wound cleansing for pressure ulcers.

BACKGROUND Pressure ulcers (also called pressure sores, bed sores and decubitus ulcers) are areas of tissue damage that occur in the very old, malnourished or acutely ill, who cannot reposition themselves. Pressure ulcers impose a significant financial burden on health care systems and negatively affect quality of life. Wound cleansing is considered an important component of pressure ulcer care. OBJECTIVES This systematic review seeks to answer the following question:What is the effect of wound cleansing solutions and wound cleansing techniques on the rate of healing of pressure ulcers? SEARCH STRATEGY We searched the Specialised Trials Register of the Cochrane Wounds Group (up to August 2005), and the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 3, 2005). We searched bibliographies of relevant publications retrieved. We contacted drug companies and experts in the field to identify studies missed by the primary search. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing wound cleansing with no wound cleansing, or different wound cleansing solutions, or different cleansing techniques, were eligible for inclusion if they reported an objective measure of pressure ulcer healing. DATA COLLECTION AND ANALYSIS Two authors extracted data independently and resolved disagreements through discussion and reference to the Cochrane Wounds Group editorial base. A structured narrative summary of the included studies was conducted. For dichotomous outcomes, relative risk (RR), plus 95% confidence intervals (CI) were calculated; for continuous outcomes, weighted mean difference (WMD), plus 95% CI were calculated. Meta analysis was not conducted, because of the small number of diverse RCTs identified. MAIN RESULTS No studies compared cleansing with no cleansing. Two studies compared different wound cleansing solutions: a statistically significant improvement in Pressure Sore Status Tool scores occurred for wounds cleansed with saline spray containing Aloe vera, silver chloride and decyl glucoside (Vulnopur) compared to isotonic saline (P value = 0.025), but no statistically significant change in healing was seen when water was compared to saline (RR 3.00, 95% CI 0.21, 41.89). One study compared cleansing techniques, but no statistically significant change in healing was seen for ulcers cleansed with, or without, a whirlpool (RR 2.10, 95% CI 0.93 to 4.76). AUTHORS' CONCLUSIONS We identified only three studies addressing cleansing of pressure ulcers. One noted a statistically significant improvement in pressure ulcer healing for wounds cleansed with saline spray containing Aloe vera, silver chloride and decyl glucoside (Vulnopur) when compared with isotonic saline solution. Overall, there is no good trial evidence to support use of any particular wound cleansing solution or technique for pressure ulcers.
An English Neural Network that Learns Texts, Finds Hidden Knowledge, and Answers Questions

Abstract In this paper, a novel neural network is proposed, which can automatically learn and recall contents from texts, and answer questions about the contents in either a large corpus or a short piece of text. The proposed neural network combines parse trees, semantic networks, and inference models. It contains layers corresponding to sentences, clauses, phrases, words and synonym sets. The neurons in the phrase-layer and the word-layer are labeled with their part-of-speeches and their semantic roles. The proposed neural network is automatically organized to represent the contents in a given text. Its carefully designed structure and algorithms make it able to take advantage of the labels and neurons of synonym sets to build the relationship between the sentences about similar things. The experiments show that the proposed neural network with the labels and the synonym sets has the better performance than the others that do not have the labels or the synonym sets while the other parts and the algorithms are the same. The proposed neural network also shows its ability to tolerate noise, to answer factoid questions, and to solve single-choice questions in an exercise book for non-native English learners in the experiments.
Reduced Plasma Thyrotropin Response to Thyrotropin Releasing Hormone After Dexamethasone Administration in Normal Subjects

Summary In order to elucidate at which level glucocorticoids act in inhibiting thyrotropin (HTSH) secretion in man, 200 wm of synthetic thyrotropin releasing hormone (TRH) were in jected intravenously in 8 normal subjects before and after oral administration of dexamethasone, 1.0 mg every 8 hr for 5 consecutive days. After dexamethasone, the mean basal plasma HTSH levels were significantly reduced, as was the plasma HTSH response to TRH: this reduced increase occurred in all subjects. The glucocorticoid did not alter significantly the serum thyroxine and trüodothyronine u~ take. The data obtained are compatible with a direct in hibiting action of dexamethasone at pituitary level
Primary Orbital Leiomyoma and Leiomyosarcoma

A case of an extremely rare primary orbital leiomyoma in a 25-year-old male patient is presented who had a lifelong history of deviation of the left eye globe with slight enophthalmos and reduced motility. Because of pain and increasing deviation of the eye the tumor was totally resected. On histologic examination the tumor showed ossification which is extremely rare so that a calcifying fibroma had to be ruled out. In immunohistochemistry, however, this tumor stained with smooth muscle antigen. Less than 2% of cells stained positive for Ki-S1, a proliferation marker. The second case is a rare primary orbital leiomyosarcoma in an 84-year-old female patient that showed massive growth. After exenteration histologic examination showed a dedifferentiated highly malignant soft tissue tumor which expressed desmin and smooth muscle actin but was negative for myoglobin, S-100 and HMB-45.
Evaluation of a pediatric palliative care educational workshop for oncology fellows

Recent efforts have focused on improving pediatric palliative care to relieve physical and psychological suffering throughout the course of illness, as well as to improve care at the end‐of‐life (EOL). One area of attention has been medical training, as healthcare providers have often reported feeling ill‐equipped to manage EOL issues. As a pilot study, we developed and evaluated a daylong educational workshop on pediatric palliative care for oncology fellows.
A relational perspective on spatial data mining

Remote sensing and mobile devices nowadays collect a huge amount of spatial data, which have to be analysed in order to discover interesting information about economic, social and scientific problems. However, the presence of a spatial dimension adds some problems to data mining tasks. The geometrical representation and relative positioning of spatial objects implicitly define spatial relationships, whose efficient computation requires a tight integration of the data mining system with the spatial DBMS. The interaction between spatially close objects causes different forms of autocorrelation, whose effect should be considered to improve the predictive accuracy of induced models and patterns. Units of analysis are typically composed of several spatial objects with different properties and their structure cannot be easily accommodated by classical double entry tabular data. In the paper, a way is shown to face these problems when a (multi-)relational data mining approach is considered for spatial data analysis. Moreover, the challenges that spatial data mining poses on current relational data mining methods are presented.
Reliability of a Greek Translation of the Life Satisfaction Index

Scores on a Greek translation of the Life Satisfaction Index were correlated . 95 with scores on the English version for a sample of 36 bilingual Greek university women. The internal reliability of the Greek translation was estimated by a coefficient alpha of . 78. Scores were significantly correlated −. 51 with those on a previously published Greek translation of the Revised UCLA Loneliness Scale and −. 37 with Social loneliness and −. 40 with Emotional loneliness. This same pattern of correlations was found when the English version of these two tests was completed by university men and women in the USA. We concluded, therefore, the Greek translation of the Life Satisfaction Index is sufficiently reliable to warrant further use in research in Greece.
Benign vascular tumors of female genital tract

Vascular tumors are rare in female genital tract (FGT). The aim of this study was to analyze the distribution of vascular tumors in FGT and to highlight their clinicopathologic features. As a retrospective study, clinical features including imaging studies, gross findings, and microscopic features of cases (ten) diagnosed as having vascular tumors of FGT over 4 years were reviewed. The age range of our cases was 12–52 years. The presenting complaint was abdominal pain/mass, postcoital bleeding, and vaginal and vulval mass. In most cases, duration of symptoms was 6 months to 2 years. Only one case had a long-standing history of 8 years. The vascular tumors occurred most commonly in ovary (six), followed by vulva (two), and one each in cervix and vagina. Clinical diagnoses ranged from cystadenoma in ovarian tumors to endocervical polyp in cervical tumor. Histologically, all were benign vascular neoplasms, ranging from hemangioma (five), lymphangioma (one), lymphangioma circumscriptum (one) to angiomatosis (two) and arteriovenous malformation (one). Thus, we conclude that vascular lesions in FGT can present with symptoms similar to epithelial malignancies and may lead to unwarranted radical surgery. Vascular lesions of cervix and vulvovaginal region pose special problem during pregnancy. Risk of Kasabach–Merritt coagulopathy has to be considered in larger vascular tumors. Most of these cases can be treated by surgery.
Thoracic ultrasound prior to medical thoracoscopy improves pleural access and predicts fibrous septation

Background and objective: Medical thoracoscopy (MT) is indicated for the investigation of unexplained pleural exudates. Not all MT units create artificial pneumothoraces because of time. Difficult pleural space access and thick fibrous adhesions may prevent MT and pleurodesis, respectively. The potential role of thoracic ultrasound (TUS) pre‐MT has not been fully evaluated. We hypothesized TUS would reduce failure to access the pleural space and enable detection of thick fibrous adhesions.
Open Source Alternatives for Business Intelligence: Critical Success Factors for Adoption

The purpose of this research is to identify critical factors that affect the adoption of Open Source Business Intelligence (OPBI) tools and to compare the differences between OPBI and Proprietary Business Intelligence (PBI) tools. Based on the Technology Acceptance Model, an organizational adoption model was designed to analyze four cases of organizations that have adopted Business Intelligence (BI) tools. The cases were documented using a tested protocol and a set of interviews. The analysis of the cases shows that organizations with fewer resources and simpler IT selection processes tend to adopt OPBI. The most cited reason for using OPBI software is cost savings. The results also reveal that for most users OPBI does not require sophisticated BI specialists and offers as many useful features as PBI tools. These findings are important to BI vendors, users, developers, and organizations interested in adopting BI technologies.
Improved hybrid leapfrog ADI-FDTD method for simulating complex electromagnetic environment effects (E3) on a warship with multi-wire antennas

An improved hybrid leapfrog ADI-FDTD method is developed for accurately characterizing complex electromagnetic environment effects (E3) on a warship with multi-wire antennas in this paper. It has the capabilities for fast extracting mutual couplings (S-parameters) among different wire antennas as well as capturing induced current and electric field distributions on such an electrically large platform. All these information will be very important for controlling and suppressing (non) intentional electromagnetic interference (IEMI) on most high-speed data-link communication systems operating at UHF/VHF bands or even higher frequencies.
Towards an information-flow model of human behaviour.

This paper is concerned with behaviour possible in an information-flow system intended explicitly as a hypothetical model for comparison with human information-handling system. A statistically self-organizing system is described in which not only normal homeostatic behaviour but also such activities as invention of fruitful hypotheses, imagination of fictitious situations, and like would find a natural place. Discussion is confined mainly to manner of concept-formation and concept-handling in such a system. It has been suggested that correlate of perception (as distinct from reception) is activity which organizes an outwardly directed internal matching response to signals from receptors. This organizing activity amounts logically to an internal representation of feature in incoming signals to which it is adaptive, i.e. feature which is thus ‘perceived’. A hierarchic structure is postulated wherein much of organizing activity is concerned with modifying probabilities of other activity. Abstract concepts and hypotheses are represented by ‘sub-routines’ of such organizing activity. These can in principle be evolved as a result of experience in a manner analogous to-or at least fruitfully comparable with-process of learning and discovery; and it is not necessary for designer to predetermine, nor possible for him to foresee, all conceptual categories in terms of which information received by system may be structured. Particular attention is directed to conditions under which such a process of concept-formation could take place with sufficient rapidity. Some of symptoms of psychopathology find apparent correlates in possible modes of malfunction of such a system. But in this, as in other respects, it is not intended to press resemblances; intention is rather to stimulate critical comparisons, in order that differences between information-flow model and real thing may continually lead to progressive refinement and enlarged understanding.
Long-term orbital propagation through differential algebra transfer maps and averaging semi-analytical approaches

Orbit perturbations are fundamental when analyzing the long-term evolution and stability of natural or artificial satellites. We propose the computation of transfer maps for repetitive dynamical systems as a novel approach to study the long-term evolution of satellite and space debris motion. We provide two examples of this technique, the evolution of high area-to-mass ratio spacecraft under solar radiation pressure and J 2 , and a sun-synchronous groundtrack repeating orbit with drag and J 2 . The results presented demonstrate the potentiality of the transfer maps for these problems. We furthermore compare this approach with averaging methods for the propagation of the orbital dynamics on the long-term, and suggest possibilities to combine differential algebra based methods with orbital elements averaging.
A grid voltage sensor-less operational approach of interconnecting distributed generating source based inverter to unbalanced generalized three-phase grid together with local load at PCC

In this paper, a novel grid voltage sensor-less operation of the generalized three-phase grid connected distributed generating source based inverter operation is proposed. The method also takes into consideration the presence of a local load at the point of common coupling (PCC). In the proposed method, the same inverter current controller is used to estimate the grid voltages and to control the inverter to achieve the control on grid active and reactive power flow along with the sinusoidal grid currents. The proposed system is implemented directly in the a-b-c frame and Spatial Repetitive Controller (SRC) is used as the main control algorithm of the proposed scheme. Experimental results are provided to show the efficacy of the proposed sensorless control methodology.
Network coding performance: An emulation experiment

This paper compares the performance of network coding to a baseline protocol that uses OLSR, SPF and NORM. The performance of each protocol suite is characterized in a three-hour militarily-relevant network topology using five (emulated) applications: video, voice, file transfer, situation awareness and messaging. Network coding provides comparable performance while using substantially less bandwidth. Simplified example scenarios are presented to provide insight into the reasons for network codingpsilas improved performance.
Pasteurization of milk containing the organism of Q fever.

acute or chronic in course and mild or severe in reaction. Explosive outbreaks of the disease occur in man and may often be traced to a common source of exposure. On the other hand, individual cases may occur sporadically in a community in which it is difficult to determine the origin of the infection. In the United States investigation of various outbreaks of Q fever have revealed that cows, sheep, or goats are the important sources of infection for man.2-5 The rickettsiae are shed in the milk of the infected animal6-9 and this vehicle provides one method whereby the organism may be transported to man's immediate environment. Early in the studies of Q fever in California it was discovered that C. burnetii could be recovered from milk pasteurized according to the recommended minimum standards.10' 11 The hazard
A Pressure Distribution Imaging Technique with a Conductive Membrane using Electrical Impedance Tomography

This paper presents a mathematical framework for a flexible pressure sensor model using electrical impedance tomography (EIT). When pressure is applied to a conductive membrane patch with clamped boundary, the pressure-induced surface deformation results in a change in the conductivity distribution. This change can be detected in the current-voltage data (i.e., EIT data) measured on the boundary of the membrane patch. Hence, the corresponding inverse problem is to reconstruct the pressure distribution from the data. Assuming that the material's conductivity distribution is constant, we derive a two-dimensional (2D) apparent conductivity (in terms of EIT data) corresponding to the surface deformation. Since the 2D apparent conductivity is found to be anisotropic, we consider a constrained inverse problem by restricting the coefficient tensor to the range of the map from pressure to the 2D apparent conductivity. This paper provides theoretical grounds for mathematically modeling the inverse problem. We deve.
Magnetotransport in AlxGax-1As quantum wells with different potential shapes

We compare the transport properties for triangular, parabolic and cubic quantum wells. We calculate the transport mobility for electrons belonging to the different subbands. We obtain the energy spacing between first and second subbands from the electron sheet density and compare results for different potential profiles. We find that experimental results are in quantitative agreements with our calculations.
Physics-aware Simulation for Object Detection and Pose Estimation

This work proposes a fully autonomous process to train Convolutional Neural Networks (CNNs) for object detection and pose estimation in setups for robotic manipulation. The application involves detection of objects placed in a clutter and in tight environments, such as a shelf. In particular, given access to 3D object models, several aspects of the environment are simulated and the models are placed in physically realistic poses with respect to their environment to generate a labeled synthetic dataset. To further improve object detection, the network selftrains over real images that are labeled using a multi-view pose estimation process. Results show that the proposed process outperforms popular training processes relying on synthetic data generation and manual annotation.
Estimating coastal wetland gain and losses in Galveston County and Cameron County, Texas, USA

Coastal wetlands serve many important ecological services. One of these important ecological services is their use as storm buffers. Coastal wetlands provide habitat for migratory birds and aquatic species and can improve water quality. In the late 1990s, the US Fish and Wildlife Service (USFWS) published a study outlining the trends of coastal wetlands from the 1950s to early 1990s. In the present study, wetland gains and losses were calculated for Galveston County and Cameron County, Texas, USA, between 2001 and 2011. Maps from the National Land Cover Database were used to determine wetland areas for the years 2001, 2006, and 2011. ArcGIS was used to compare land cover between the study periods to determine overall wetland losses and gains. A statistical analysis was performed between wetland loss and population data to determine whether increased population density led to a higher loss of wetlands. Our analysis indicates that wetland loss is still occurring, however at a lower rate of loss (0.14%–0.18% annually) than the USFWS study predicted earlier (2.7%). In addition, the majority of wetland losses were due to conversion to upland areas. We found a positive correlation between increased population density and decreased wetland area; however, the trend was not significant. The present study shows how the majority of wetland loss in Galveston and Cameron counties is occurring as a result of increased upland areas. In addition, the present study shows that the use of online mapping systems can be used as a low‐cost alternative to assess land changes when field tests are not feasible.

The role of osmoregulation in the pathophysiology and management of Severe Ovarian Hyperstimulation Syndrome

Abstract Severe Ovarian Hyperstimulation Syndrome (OHSS), with an incidence of 1–2% of superovulation cycles, remains one of the most important complications of gonadotrophin use in assisted reproductive technologies because of its associated morbidity and rarely, mortality. Despite the wealth of scientific and clinical interest that this iatrogenic complication has generated, its pathophysiology is still not adequately elucidated and its management has thus remained empirical. Disorders of salt and water balance are two very important features that have been reported during severe OHSS. Some of the clinical and biochemical changes resulting from this disorder of salt and water balance are similar to those previously reported in pregnancy and liver cirrhosis. The pathophysiology of these clinical changes has been explained in part in pregnancy and liver cirrhosis by changes in osmoregulation function. It is this similarity in the clinical and biochemical changes in OHSS, pregnancy and liver cirrhosis that has prompted the investigation of the role of osmoregulation function in the pathophysiology of OHSS. The current article has been written to provide further details in support of recent excellent articles and guidelines, highlighting the physiological basis and rationale governing some aspects of, and the role of osmoregulation in the management of the OHSS syndrome.
