Video modelling to educate patients.

BACKGROUND Changes in health care delivery in the United States of America due to economic pressures have required nurses to develop innovative instructional materials for educating patients and families. Educational materials such as videotapes, specifically designed to provide information and promote active participation in treatment decisions, can be effective tools for empowering patients. A comprehensive analysis in 1988 concluded that the concept of 'video modelling' or 'behavioural modelling' offered the greatest benefit of videotaped presentations. AIM OF THE STUDY The purpose of this integrative literature review was to examine the concept of video modelling and its applications in clinical practice. METHODS A computer search of the electronic databases of Medline and CINHAL between 1990 and 1999 produced a total of 40 research studies on video instruction for patients. Based on criteria for inclusion, 18 research studies involving video modelling were reviewed and three major uses were identified: (1) assisting decision making regarding treatment options; (2) reducing pre-procedural anxiety and improving coping skills; and (3) teaching self-care practices. RESULTS The studies reviewed included a variety of research designs, clinical settings, and patient populations. Despite these differences, several benefits to the use of video modelling were found. Patients who viewed videotapes regarding treatment options had a greater understanding of the risks and benefits of those choices and were more apt to be active participants in decision making. Collective results of the studies focusing on stress and coping revealed that preparatory videotapes using video modelling could have a positive effect on reducing anxiety and physiological arousal during stressful procedures. With self-care practices, several of the studies found that there was an increase in desired behaviours in people whose educational programmes included video modelling. CONCLUSIONS The use of video modelling has potential benefits for clinical practice in facilitating knowledge acquisition, reducing preparatory anxiety, and improving self-care. Nurses must become more actively involved in evaluating various teaching approaches used with patients to enhance practice and outcomes.
Prevalence of abdominal obesity in adolescents: a systematic review

The objectives of this study were to (i) review extant literature on the prevalence of abdominal obesity (AO) in adolescents of both sex (10–19 years old); (ii) analyse the cut‐off points used for the diagnosis of AO and (iii) compare its prevalence between developed and developing countries. The search was carried out using online databases (MEDLINE, Web of Science, EMBASE, SPORTDiscus, SCIELO and BioMed Central), references cited by retrieved articles and by contact with the authors, considering articles published from the establishment of the databanks until 19 October 2009. Only original articles and those using waist circumference in the diagnosis were considered. Twenty‐nine studies met the inclusion criteria. Fourteen of these studies were performed in developed countries. The prevalence of AO varied from 3.8% to 51.7% in adolescents from developing countries. The range of results was smaller among developed countries; with values from 8.7% to 33.2%. Eighteen different cut‐off points were used. It was concluded the AO prevalence is high among adolescents, but is not clear what sex has a higher proportion and it is greater in adolescents from developing countries; however, there is no consensus in the literature about the criteria to be used.
Stochastic Geometry Analysis for Mean Interference Power and Outage Probability in THz Networks

Mean interference power and probability of outage in the THz band (0.1–10 THz) networks are studied. The frequency band has potential for enabling future short range communication systems because of the large available spectrum resources. This can enable huge data rates, or on the other hand, large numbers of users sharing the resources. The latter case is closely related to the subject of this paper on interference modeling for dense THz networks with stochastic geometry. We use it to estimate the average behavior of random networks. The literature has shown convenient closed form solutions for the mean interference power in ultrahigh frequency band (UHF, 300 MHz – 3 GHz). Those are not always readily applicable for the THz band. This is especially the case when THz band is modeled with the molecular absorption and free space path loss. Still, the mean interference power does have closed form solutions in all cases, but in some, numerical approximations have to be used. We provide the derivation and analysis of the mean interference power and the outage probability. The results are verified with computer simulations.
La politique étrangère des Etats baltes

Au debut de la periode postcommuniste, la politique etrangere des pays Baltes s'orientait presque singulierement vers une securite accrue. Cela signifiait surtout une normalisation des relations avec la Russie et une integration dans les structures de l'Europe de l'Ouest. Les efforts baltiques ont ete compliques par la necessite d'institutionnaliser la politique des nationalites et par un environnement externe extremement fluide. Ce dernier fut domine par un accroissement du chaos en Russie et par une incertitude a l'Ouest quant a la forme d'une Europe postcommuniste. Les premiers resultats en matiere de politique etrangere ont abouti, paradoxalement, a une intensification du dilemme de securite des pays Baltes vis-a-vis de la Russie ainsi qu'a une diminution de la pertinence du concept de « pays Baltes » en tant que categorie politiquement honorable.

Heart failure in young adults: 20-year trends in hospitalization, aetiology, and case fatality in Sweden

Aims To describe trends in incidence and case fatality among younger (18–54 years) and older (55–84 years) Swedish patients with heart failure (HF). Methods and results Through linking the Swedish national hospital discharge and the cause-specific death registries, we identified patients aged 18–84 years that were discharged 1987–2006 with a diagnosis of HF. Age-specific mean incidence rates per 100 000 person-years were calculated in four 5-year periods. Kaplan–Meier survival curves were plotted up to 3 years. From 1987 to 2006, there were 443 995 HF hospitalizations among adults 18–84 years. Of these, 4660 (1.0%) and 13 507 (3.0%) occurred in people aged 18–44 and 45–54 years (31.6% women), respectively. From the first to the last 5-year period, HF incidence increased by 50 and 43%, among people aged 18–34 and 35–44 years, respectively. Among people ≥45 years, incidence peaked in the mid-1990s and then decreased. Heart failure in the presence of cardiomyopathy increased more than two-fold among all age groups. Case fatality decreased for all age groups until 2001, after which no further significant decrease <55 years was observed. Conclusion Increasing HF hospitalization in young adults in Sweden opposes the general trend seen in older patients, a finding which may reflect true epidemiological changes. Cardiomyopathy accounted for a substantial part of this increase. High case fatality and lack of further case fatality reduction after 2001 are causes for concern.
Aggregated Signatures for Chaining: A Secure Provenance Scheme

With the explosion of information in daily life, determining the trustworthiness of data has become inevitable. As data from different sources can be used in critical applications such as health-care and military for decision making, data provenance plays an important role to gauge the trustworthiness of data. Although, lots of research has been conducted out on provenance generation, provenance management/storage and provenance dissemination in various fields of computing such as: databases, scientific workflows, file systems, distributed cloud computing, and wireless sensor networks. However, security of data provenance has gained limited attention from research community. Since provenance generates a Directed Acyclic Graph (DAG) and chain structure, traditional security solutions are not directly applicable. In this paper, a novel aggregated signature based chaining scheme is presented. The proposed scheme ensures confidentiality, integrity, non-repudiation and availability in a distributed environment to achieve secure provenance. Differentfrom existing work, we assume a stronger attacker model inwhich more than two consecutive colluding users can launchattacks on provenance chain. Security analysis shows that ourscheme can detect such attacks. We have evaluated our proposed scheme empirically and analytically to validate its effectiveness. Our results show that our scheme outperforms existing schemes in term of computation and security.
The importance of importance: adolescents' perceptions of parental communication about sexuality.

High-schoolers (n=298) completed surveys describing the frequency and importance of mother and father communication about 20 different sex-related topics. There were four domains of sex-related topics: Development and Societal Concerns, Sexual Safety, Experiencing Sex, and Solitary Sexual Activity. Adolescents reported infrequent communication which varied by domain and gender of parent and teen. When communication occurred, it was most frequently about the first two domains. Mothers were reported as more frequent communicators about sexuality than fathers and girls received more communication than boys. Young people rated parental communication about sexuality as unimportant, with findings that paralleled those for frequency. Examination of the match between frequency and perceived importance of parental communication revealed more matches than mismatches. Almost all matches resulted from responses indicating low frequency and little importance. Most mismatches reflected a perception of insufficient rather than excessive parental communication about sexuality. It is argued that we need to consider the relative importance given to parental communication, as well as its frequency, if parents are to be effective communicators.

Spontaneous and experimentally induced uptake of radioactive iodine in metastases from thyroid carcinoma; a preliminary report.

METASTATIC carcinoma of the thyroid can be successfully treated with radioiodine when the lesions concentrate this isotope (1). The usefulness of this method depends upon the percentage of cases in which such concentration can be demonstrated. A technique of inducing uptake of radioiodine in metastases that previously showed none would increase the usefulness of the method. Clinically we have been successful in inducing such uptake in several cases with subsequent amelioration of the disease. In a recent publication by Marinelli et at. (2), it is reported that “approximately 15 per cent of thyroid cancers may be expected to accumulate radioactive iodine in some degree. ” This conclusion is based on findings in a selected group of 19 cases modified by an estimation of relative frequency of various types of thyroid carcinoma. The present paper is a report on 14 unselected cases of metastatic thyroid carcinoma studied at Montefiore Hospital up to June 1947.
ERDT: Energy-Efficient Reliable Decision Transmission for Intelligent Cooperative Spectrum Sensing in Industrial IoT

Due to harsh environment, large number of sensors, limited energy, and spectrum scarcity, intelligent sensing becomes a key issue to enable many practical applications in industrial Internet of Things (IoT). In such an industrial environment with noise and interference, an efficient cooperative spectrum sensing (CSS) scheme can achieve spectrum sharing between primary users (PUs) and secondary users (SUs), and effectively solve the spectrum scarcity and reduce energy consumption to make the IoT smarter. As a vital part of CSS, decision transmission (DT) between SUs and fusion center (FC) plays a crucial role. In traditional DT, each SU will transmit its local decision to FC with orthogonal channel in each sensing, which does not consider the packet error and packet loss due to noise during transmission, and aggravates spectrum scarcity and energy consumption. An energy-efficient reliable DT (ERDT) scheme is proposed to enhance CSS in industrial IoT, which considers both packet error and packet loss. First, the CSS mathematical model based on DT is formulated. Second, with rigorous mathematical deduction, the correct decision probability and the energy consumption are analyzed for both ERDT and DT based on logic OR-rule and AND-rule under three cases, respectively: 1) bit error only; 2) packet loss only; and 3) both bit error and packet loss. Detailed simulation results show that, compared with DT, the proposed ERDT can increase correct decision probability and reduce energy consumption for CSS under three different cases. When the existence probability of PU is 50%, the energy consumption of ERDT is only half of that of DT in CSS. Furthermore, when there are 30 SUs in CSS, the existence probability of PU is 50%, both pocket loss rate and bit error rate are 0.05, and the correct decision probability of ERDT is approaching to 1 for CSS in industrial IoT.
Delineation of the cis-acting element mediating EBNA-2 transactivation of latent infection membrane protein expression

To delineate the cis-acting element through which EBNA-2 transactivates latent membrane protein 1 (LMP1), we assayed the effect of EBNA-2 on the activity of LMP1 promoter upstream deletion mutants in the context of the LMP1 or heterologous promoters controlling chloramphenicol acetyltransferase (CAT) reporter gene expression in Epstein-Barr virus-negative Burkitt lymphoma cells. Assays of progressive 5' deletions of the LMP1 promoter revealed low constitutive and at least eightfold EBNA-2-stimulated activity from -512 to +40 (-512/+40), -334/+40, and -234/+40 LMP1CAT plasmids. More extensive 5'-deleted -205/+40, -155/+40, and -147/+40 LMP1CAT plasmids also had low constitutive activity but were not EBNA-2 responsive. The most 5'-deleted -55/+40 LMP1CAT plasmid had moderate constitutive activity and was not EBNA-2 inducible. Either orientation of the -334/+40 LMP1 sequence conferred EBNA-2 responsiveness when positioned upstream of an enhancerless simian virus 40 or herpes simplex virus thymidine kinase (TK) promoter. EBNA-2 and the cis-acting LMP1 DNA were both required to increase TK promoter-initiated mRNA, indicating that the EBNA-2 effect is at the transcriptional level. Further deletion analysis of the EBNA-2-responsive cis-acting element defined a -234/-92 LMP1 DNA fragment which conveyed EBNA-2 responsiveness to the herpes simplex virus TK promoter. The 5' 30 bp between -234 and -205 were essential for EBNA-2 responsiveness. Thus, these experiments define a 142-bp cis-acting element which is sufficient for conveying EBNA-2 responsiveness and an essential 30-bp component of that element. The role of this element in LMP1 and LMP2B expression and its possible role in LMP2A expression are discussed.
Helicobacter pylori infections and gastric cancer: The West African experience

The prevalence of Helicobacter Pylori (Hp) in West Africa is high and infection occurs early in childhood but there are very few studies on association of Hp with GC. Despite the high prevalence of Hp, gastric cancer incidence is low and precancerous lesions are rare. Although most strains of Hp are positive for the virulent factor cagA gene as well as vacA s1, m1 or s1, m2; there is no consistent association with GC. Some studies have attributed the low incidence of GC to low prevalence of strains with multiple EPIYA-C segments of CagA gene and mixed infection by cagA positive and cagA negative strains which may be protective. Studies have also suggested that diets rich in anti-oxidants such as fresh fruits and vegetables decrease risk of GC while high salt diet increases the higher expression of CagA. More studies are therefore required to explain the dissociation between prevalence of Hp infection and gastric cancer in WA.
TOA estimation with dynamic-threshold for IR-UWB system based on quantized compressed sensing

Compressed sensing (CS) theory provides a new solution for the possibility of using impulse radio ultra-wideband (IR-UWB) for high-precision time of arrival (TOA) estimation. Because of the sparsity of IR-UWB signals, the CS theory enables the reconstruction of signals from a small set of random measurements at a sub-Nyquist rate. In current studies involving CS-based sampling architectures, the quantization process is usually idealized and the TOA estimation threshold is fixed. In this paper, the influence of quantization noise is fully considered, and a TOA estimation method for IR-UWB system with overloading quantization is proposed. Further, a dynamic-threshold setting model is proposed for the TOA estimation method based on the analysis of both thermal noise and quantization noise. Simulation results show that the proposed method can achieve sub-nanosecond TOA estimation accuracy under the quantized CS framework, and the effectiveness of the proposed dynamic-threshold setting model is verified.
Discretization Process Impact on Compressed LFM Signal Parameters

Digital signal processing is a backbone of a modern radar receiver. Signal discretization and its side effects have significant influence on radar performance. It makes crucial the awareness of the effects, as well as its qualitative and quantitative evaluation. The paper presents the problem of random displacement effect of pulse beginning in accordance to the closest discrete time value. This effect has strong impact on characteristics of pulse compression filter. Characteristics evaluation of the discretization process has been performed on the base of proposed discrete time generation algorithm. The testing results are shown, as well as its discussion and some practical conclusions.

Areas covered in this review: This review focuses on the recent strategies and outcomes that have been developed around the use of liposomes in nasal vaccination. What the reader will gain: The various formulation parameters, including lipid composition, size, charge and mucoadhesiveness, that have been investigated in the design of liposomal vaccine candidates dedicated to nasal vaccination are outlined. Also, an overview of the immunological and protective responses obtained with the developed formulations is presented. Take home message: This review illustrates the high potential of liposomes as nasal vaccine delivery systems.
Modulating NAD+ metabolism, from bench to bedside

Discovered in the beginning of the 20th century, nicotinamide adenine dinucleotide (NAD+) has evolved from a simple oxidoreductase cofactor to being an essential cosubstrate for a wide range of regulatory proteins that include the sirtuin family of NAD+‐dependent protein deacylases, widely recognized regulators of metabolic function and longevity. Altered NAD+ metabolism is associated with aging and many pathological conditions, such as metabolic diseases and disorders of the muscular and neuronal systems. Conversely, increased NAD+ levels have shown to be beneficial in a broad spectrum of diseases. Here, we review the fundamental aspects of NAD+ biochemistry and metabolism and discuss how boosting NAD+ content can help ameliorate mitochondrial homeostasis and as such improve healthspan and lifespan.
Design and implementation of an FTIR camera-based multi-touch display

The personal computer is quickly becoming the center of an all-encompassing multimedia environment. An environment that spans information creation and exchange, entertainment, and near real-life experiential environment manipulation. With such a deluge of media experiences, a new Human-Computer Interface is needed to allow the user better direct manipulation of presented information. In this paper, we present the design and implementation of a camera-based direct interaction multi-touch display. This display replaces the limited interaction afforded by the outdated display monitor and mouse with interactive hands-on manipulation. The paper discusses the different techniques possible for implementing such a display and documents the implementation based on the Frustrated Total Internal Reflection (FTIR) technology.
Endosomal Trafficking and Proprotein Convertase Cleavage of cis Golgi Protein GP73 Produces Marker for Hepatocellular Carcinoma

Serum GP73 levels are significantly increased in patients with hepatocellular carcinoma (HCC), potentially providing a marker for early detection. However, GP73 is an integral membrane protein localized to the cis Golgi and is not known to be secreted. Based on its presence in sera, we sought to determine whether GP73 might normally be released from cells and to elucidate the mechanism of this release. Indeed, a soluble form of GP73 was released from cultured cells and compared with the Golgi‐localized full‐length protein, the molecular weight was slightly reduced, suggesting that cleavage releases the GP73 ectodomain. Sequence analysis revealed a proprotein convertase (PC) consensus site, and, indeed, the ubiquitous PC furin was capable of cleaving purified GP73. Further, alanine substitutions in the PC site blocked both the in vitro and the in vivo cleavage of GP73. Using a cleavage‐specific antibody, cleaved GP73 was found in the trans Golgi network and endosomes, suggesting that GP73 cleavage occurs as GP73 cycles distal to the early Golgi. We conclude that the endosomal trafficking of GP73 allows for PC‐mediated cleavage, resulting in GP73 secretion, and provides a molecular mechanism for its presence as a serum biomarker for HCC.
Johnson homomorphisms and actions of higher‐rank lattices on right‐angled Artin groups

Let G be a real semisimple Lie group with no compact factors and finite centre, and let Λ be an irreducible lattice in G. Suppose that there exists a homomorphism from Λ to the outer automorphism group of a right‐angled Artin group AΓ with infinite image. We give a strict upper bound to the real rank of G that is determined by the structure of cliques in Γ. An essential tool is the Andreadakis–Johnson filtration of the Torelli subgroup 𝒯(AΓ) of Aut(AΓ). We answer a question of Day relating to the abelianization of 𝒯(AΓ), and show that 𝒯(AΓ) and its image in Out(AΓ) are residually torsion‐free nilpotent.
