Four Endoscopic Predictors of Carcinoma as a Final Diagnosis after Endoscopic Resection of Forceps Biopsy-proven Gastric Adenomas

Background/Aims: Previous studies have reported that the frequency of re-diagnosing as carcinoma after endoscopic resection of gastric adenoma ranges between 6% and 47%. Therefore, specific endoscopic findings have been used to predict re-diagnosing as carcinoma after endoscopic resection of gastric adenoma at our center. We evaluated whether there is a use for these indicators for predicting carcinoma as a final diagnosis in forceps biopsy-proven adenomas. Materials and Methods: We investigated 378 tissue samples from 308 patients. Classification of specimens as adenoma and carcinoma was based on postresection specimen. Endoscopic findings were reviewed for tumor location, size, gross appearance, surface nodularity, central concavity, surface color, and presence of ulcers. These variables were analyzed and compared between the adenoma group (275 cases) and the carcinoma group (103 cases), assigned based on post-resection diagnosis. Results: The mean patient age was 61, and 227 of the patients were male. The mean lesion diameter was 14.9±8.1 mm in the adenoma group and 17.9±9.3 mm in the carcinoma group. A lesion size of 15 mm or greater, depressed appearance, surface nodularity, central concavity, and presence of high-grade dysplasia were all independently associated with re-diagnosing as carcinoma after endoscopic resection. Conclusions: Lesion size of 15 mm or greater, depressed-type appearance, central concavity, and nodular surface are feasible predictors of carcinoma as a final diagnosis in forceps biopsy-proven adenomas. Physicians need to recommend immediate endoscopic resection for forceps biopsy-proven adenomas with these four independent features so as not to miss the optimal window for treatment.

National Survey of Stop Smoking Service Provision in Hospitals in Great Britain: Current Practice, Barriers and Facilitators

Aim: The UK National Health Service (NHS) funds the Specialist Stop Smoking Service (SSS) that provides help to smokers across various settings. While community services are extensively monitored, little data exist on hospital services. We set out to review current practice and identify barriers and facilitators associated with implementing smoking cessation services in UK hospitals. Methods: Hospital service leads were identified from a national online forum and invited, via email, to take part in a survey that assessed service characteristics, referral pathways, interventions used, service throughput and outcome, barriers, facilitators and suggestions for service improvement. Results: Data from 39 services were included in analyses. There was considerable variation in how services were staffed and run. Services employed on average two full time equivalent staff (FTES) and covered two hospitals. The majority (85%) were funded via local public health budget rather than by the hospitals themselves. Most referrals were received from ward nurses over the telephone and services received on average 9 referrals a week per 1 FTES. The majority provided behavioural support on wards and referred patients to community SSS on discharge. All inpatient services were able to provide nicotine replacement treatment, 57% additionally offered varenicline and 35% bupropion. Conclusions: Smoking cessation provision in UK hospitals is currently highly variable. Ensuring that smokers are referred to treatment is the main challenge. Guidance is needed to help services optimise referral routes and unify data collection. Research is needed into what service models produce the best outcomes.
An improved reverse converter for the moduli set {2n-1, 2n, 2n+1, 2n+1-1}

In this paper, a new reverse converter for the moduli set {2n−1, 2n, 2n+1, 2n+1−1} is presented. We improved a previously introduced reverse converter architecture for deriving a high-speed hardware design. Hardware architecture of the proposed converter is based on adders, without the need for ROM or Multiplier. The presented design resulted in a significant reduction in conversion delay in comparison to the last reverse converter for the moduli set {2n − 1, 2n, 2n + 1, 2n+1 − 1}.
An Empirical Examination of the Concern for Information Privacy Instrument

The arrival of the ? information age? holds great promise in terms of providing organizations with access to a wealth of information stores. However, the free exchange of electronic information also brings the threat of providing easy, and many times unwanted, access to personal information. Given the potential backlash of consumers, it is imperative that both researchers and practitioners understand the nature of consumers' concern for information privacy and accurately model the construct within evolving research and business contexts. Drawing upon a sample of 355 consumers and working within the framework of confirmatory factor analysis, this study examines the factor structure of the concern for information privacy (CFIP) instrument posited by Smith et al. (1996). Consistent with prior findings, the results suggest that each dimension of this instrument is reliable and distinct. However, the results also suggest that CFIP may be more parsimoniously represented as a higher-order factor structure rather than a correlated set of first-order factors. The implication of these results is that each dimension of CFIP as well as the supra dimension derived from the associations among dimensions are important in capturing CFIP and associating the construct to other important antecedents and consequences.
Nitrate and Nitrite Intake and the Risk for Type 1 Diabetes in Finnish Children

The intakes of nitrate and nitrite of children and their parents from food and drinking water were estimated in a Finnish nation‐wide case‐control study on the epidemiology of Type 1 diabetes. The study population consisted of 684 case and 595 control children; 548 case‐control pairs of fathers; and 620 case‐control pairs of mothers. The consumption frequencies of foods which are important sources of nitrate and nitrite were assessed by structured questionnaire. Nitrate and nitrite concentration data were collected from Finnish water works. Diabetic children's and their mothers' daily dietary intake of nitrite was greater compared with that of control children and mothers (for case and control children 0.9 mg vs 0.8 mg, for case and control mothers 0.9 mg vs 0.8 mg, p<0.001). Case mothers compared with control mothers received less (p<0.05) nitrate from their diet. No differences were observed in the intake of nitrate or nitrite from drinking water. Dietary nitrite intake of children (odds ratios and 95% confidence intervals for the second, third, and fourth quartile 1.16, 0.82–1.65; 1.49, 1.06–2.10; 2.32, 1.67–3.24, respectively) and mothers (odds ratios and 95% confidence intervals for the second, third, and fourth quartile 1.15, 0.76–1.74; 1.29, 0.87–1.91; 1.98, 1.35–2.90, respectively) was positively associated with the risk for Type 1 diabetes independently from length of mother's education, child's or mother's age, place of residence or mother's smoking status. The present study gives supporting evidence that dietary nitrites, from which N‐nitroso compounds can be formed in foods and in the human body, are associated with the development of Type 1 diabetes in man.
Prediction in Economic Networks

We define an economic network as a linked set of entities, where links are created by actual realizations of shared economic outcomes between entities. We analyze the predictive information contained in a specific type of economic network, namely, a product network, where the links between products reflect aggregated information on the preferences of large numbers of individuals to co-purchase pairs of products. The product network therefore reflects a simple “smoothed” model of demand for related products. Using a data set containing more than 70 million observations of a nonstatic co-purchase network over a period of two years, we predict network entities' future demand by augmenting data on their historical demand with data on the demand for their immediate neighbors, in addition to network properties, specifically, local clustering and PageRank. To our knowledge, this is the first study of a large-scale dynamic network that shows that a product network contains useful distributed information for demand prediction. The economic implications of algorithmically predicting demand for large numbers of products are significant.
Investigation of the relationship between the duration of postoperative mechanical ventilation and complication incidence following coronary arterybypass graft

BACKGROUND The relationship between prolonged intubation period and postoperative complication incidence following cardiac surgery was investigated. MATERIAL/METHOD Evaluated were 237 adult patients who underwent coronary artery bypass graft operation, of whom 115 (group I) had intubation periods of more than 24 hrs (mean: 56.1+/-39.1 hrs) and 122 (group II) less than 24 hrs (mean: 16.25+/-14.6 hrs). Preoperative and postoperative pulmonary function test values as well as postoperative changes in the two groups were compared. RESULTS Mean hospital stay for group I and II patients were determined as 24.6+/-2.04 and 10.61+/-3.04 days, respectively (p<0.0001). The preoperative pulmonary function test results compared with the predicted values for both groups were similar. A significant decrease was determined in the postoperative pulmonary function test values in both groups, but the decrease in group I was significantly higher than in group II. Pulmonary complications developing in groups I and II were 26.09% (30 patients) and 7.38% (9 patients), respectively (p<0.0001). Also, total general complications were 39.14% (45 patients) and 13.12% (16 patients), respectively. CONCLUSION Under similar conditions, the patients whose partial bypass time and aortic clamp period were significantly longer needed to be ventilated for more than 24 hours, being related to late complications following bypass operation, and the complication risk of this group was 3.5 times higher than for those who remained intubated less than 24 hours.
Central and peripheral nervous system infection, immunity, and inflammation in the nonhuman primate model of lyme borreliosis

The relationship between chronic infection, antispirochetal immunity, and inflammation is unknown in Lyme neuroborreliosis. In the nonhuman primate (NHP) model of Lyme neuroborreliosis, we measured spirochetal density in the nervous system and other tissues by polymerase chain reaction and correlated these values to anti‐B. burgdorferi antibody in the serum and cerebrospinal fluid, and to inflammation in tissues. Despite substantial presence of B. burgdorferi, the causative agent of Lyme borreliosis, in the central nervous system, only minor inflammation was present there, though skeletal and cardiac muscle, which contained similar levels of spirochete, were highly inflamed. Anti‐B. burgdorferi antibody was present in the cerebrospinal fluid but was not selectively concentrated. All infected animals developed anti‐B. burgdorferi antibody in the serum, but increased amplitude of antibody was not predictive of higher levels of infection. These data demonstrate that Lyme neuroborreliosis is a persistent infection, that spirochetal presence is a necessary but not sufficient condition for inflammation, and that antibody measured in serum may not predict the severity of infection.
Predictive Analytics for Readmission of Patients with Congestive Heart Failure

Mitigating preventable readmissions, where patients are readmitted for the same primary diagnosis within 30 days, poses a significant challenge to the delivery of high-quality healthcare. Toward this end, we develop a novel, predictive analytics model, termed as the beta geometric Erlang-2 BG/EG hurdle model, which predicts the propensity, frequency, and timing of readmissions of patients diagnosed with congestive heart failure CHF. This unified model enables us to answer three key questions related to the use of predictive analytics methods for patient readmissions: whether a readmission will occur, how often readmissions will occur, and when a readmission will occur. We test our model using a unique data set that tracks patient demographic, clinical, and administrative data across 67 hospitals in North Texas over a four-year period. We show that our model provides superior predictive performance compared to extant models such as the logit, BG/NBD hurdle, and EG hurdle models. Our model also allows us to study the association between hospital usage of health information technologies IT and readmission risk. We find that health IT usage, patient demographics, visit characteristics, payer type, and hospital characteristics, are significantly associated with patient readmission risk. We also observe that implementation of cardiology information systems is associated with a reduction in the propensity and frequency of future readmissions, whereas administrative IT systems are correlated with a lower frequency of future readmissions. Our results indicate that patient profiles derived from our model can serve as building blocks for a predictive analytics system to identify CHF patients with high readmission risk.
Allocation of Virtual Machines in Cloud Data Centers—A Survey of Problem Models and Optimization Algorithms

Data centers in public, private, and hybrid cloud settings make it possible to provision virtual machines (VMs) with unprecedented flexibility. However, purchasing, operating, and maintaining the underlying physical resources incurs significant monetary costs and environmental impact. Therefore, cloud providers must optimize the use of physical resources by a careful allocation of VMs to hosts, continuously balancing between the conflicting requirements on performance and operational costs. In recent years, several algorithms have been proposed for this important optimization problem. Unfortunately, the proposed approaches are hardly comparable because of subtle differences in the used problem models. This article surveys the used problem formulations and optimization algorithms, highlighting their strengths and limitations, and pointing out areas that need further research.

OBJETIVO: relacionar o tipo de parto e as caracteristicas do perineo com valores da pressao muscular perineal (PMP) mensurada em primiparas nas posicoes deitada e sentada com a musculatura perineal em repouso e em contracao maxima. METODOS: estudo quantitativo do tipo transversal, realizado em maternidade conveniada ao Sistema Unico de Saude (SUS) do municipio de Sao Paulo. A casuistica, obtida por conveniencia, foi de 95 primiparas de termo. A avaliacao ocorreu entre o 40o e o 45o dia. Realizaram-se entrevista, exame fisico e mensuracao da PMP por meio do perineometro de Kegel. A mensuracao foi realizada nas posicoes deitada e sentada, com a musculatura em repouso e em contracao maxima, sendo considerada a media de tres afericoes para cada posicao e estado muscular. RESULTADOS: 76,8% (73) das primiparas tiveram parto vaginal e 23,2% (22) cesarea. No pos-parto vaginal, observou-se perineo integro em 18,9% (18), com rotura perineal em 24,2% (23) e com episiotomia em 33,7% (32). Os valores obtidos da PMP foram em: posicao deitada/musculatura em repouso, 18,9 mmHg; deitada/musculatura em contracao maxima, 30,7 mmHg; sentada/musculatura em repouso, 34,5 mmHg; sentada/musculatura em contracao maxima, 46,5 mmHg. CONCLUSAO: nao houve associacao entre o tipo de parto e as condicoes perineais e a pressao muscular perineal.
Light my way: visualizing shared gaze in the car

In demanding driving situations, the front-seat passenger can become a supporter of the driver by, e.g., monitoring the scene or providing hints about upcoming hazards or turning points. A fast and efficient communication of such spatial information can help the driver to react properly, with more foresight. As shown in previous research, this spatial referencing can be facilitated by providing the driver a visualization of the front-seat passenger's gaze. In this paper, we focus on the question how the gaze should be visualized for the driver, taking into account the feasibility of implementation in a real car. We present the results from a driving simulator study, where we compared an LED visualization (glowing LEDs on an LED stripe mounted at the bottom of the windshield, indicating the horizontal position of the gaze) with a visualization of the gaze as a dot in the simulated environment. Our results show that LED visualization comes with benefits with regard to driver distraction but also bears disadvantages with regard to accuracy and control for the front-seat passenger.
Managing Citizens' Uncertainty in E-Government Services: The Mediating and Moderating Roles of Transparency and Trust

This paper investigates how citizens’ uncertainty in e-government services can be managed. First, we draw from uncertainty reduction theory, and propose that transparency and trust are two key means of reducing citizens’ uncertainty in e-government services. Second, we identify two key sets of relevant drivers of e-government service use: (1) information quality characteristics, i.e., accuracy and completeness; and (2) channel characteristics, i.e., convenience and personalization. We propose that the means of uncertainty reduction, information quality characteristics, and channel characteristics are interrelated factors that jointly influence citizens’ intentions to use e-government. We tested our model with 4,430 Hong Kong citizens’ reactions to two e-government services: government websites and online appointment booking. Our results show that the information quality and channel characteristics predict citizens’ intentions to use e-government. Furthermore, transparency and trust mediate as well as moderate the effects of information quality and channel characteristics on intentions. A follow-up survey found that citizens’ intentions predict use and ultimately, citizens’ satisfaction.
Research Note - Leader Influence on Sustained Participation in Online Collaborative Work Communities: A Simulation-Based Approach

From the perspective of leader-member exchange theory, we investigate how two forms of leadership style (uniform leader-member exchange (ULMX) and differential leader-member exchange (DLMX)) impact member participation in online collaborative work communities (OCWC). Furthermore, based on computer simulations, we also examine the moderating impact of key contextual factors on the relationship between leadership style and member contributions. Efficacy of leadership style in OCWCs is greatly influenced by environmental conditions. DLMX is more effective in sustaining member commitment under high environmental uncertainty, regardless of network size and structure. ULMX is more effective in decentralized structures and during the early stage of community growth. The simulation-based insights suggest that supervisory behavior does matter to member retention and sustained participation in OCWCs, but its impact is significantly moderated by many contextual factors, such as community size, structure, maturity, a.
Telerehabilitacja dorosłych pacjentów korzystających z aparatów słuchowych i/lub implantów ślimakowych

Telemedicine is the newest form of healthcare combining elements of telecommunications, informatics and medicine. Technical progress in connection with expert experience imply the rise of the remote programs of care for patients from different age groups and with different types of health problems. Telerehabilitation enables the delivery of rehabilitation services to a user through telecommunications network and the Internet. In relation to persons with hearing loss, including users of hearing aids and/or hearing implants, rehabilitation activities are also included in programs categorized as teleaudiology or telehealth. This paper presents the overview of the most important reports from literature (papers, doctoral theses, preliminary reports, abstracts and presentations) as well as reports of implementation of EU programs, which summarize research and practical actions addressed to adult users of auditory prostheses within broadly understood telerehabilitation. It discusses implemented management models, recipients and providers of programs, forms of service delivery and impressions of the participants of therapy programs organized in a ‘tele’ format. The utilization of technology to organize and provide care for persons with hearing loss brings about significant benefits, especially in places were lack of specialists or limited access to them determine the efficiency of specific medical management programs.

On Direct vs. Indirect Peer Influence in Large Social Networks

With the availability of large-scale network data, peer influence in social networks can be more rigorously examined and understood than before. Peer influence can arise from immediate neighbors in the network (formally defined as cohesion or direct ties with one-hop neighbors) and from indirect peers who share common neighbors (formally defined as structural equivalence or indirect ties with two-hop neighbors). While the literature examined the role of each peer influence (direct or indirect) separately, the study of both peer network effects acting simultaneously was ignored, largely because of methodological constraints. This paper attempts to fill this gap by evaluating the simultaneous effect of both direct and indirect peer influences in technology adoption in the context of caller ringback tone (CRBT) in a cellular telephone network, using data from 200 million calls by 1.4 million users. Given that such a large-scale network makes traditional social network analysis intractable, we extract many de.
The results at nine to twelve years of the use of a hydroxyapatite-coated femoral stem

We describe the clinical and radiological outcome of 100 consecutive total hip replacements in 86 patients using the JRI Furlong hydroxyapatite-coated femoral component. The follow-up was 100% at a mean of ten years (9.0 to 12.0). All 54 living patients (62 hips) were examined annually. Their mean Merle d'Aubigne score was 5.8/5.6/4.6. A total of 32 patients had died. Their notes at the last annual assessment recorded a similar outcome to that of the living patients. Radiographs showed no radiolucent lines around any femoral component and there were no signs of impending failure. One patient required excision arthroplasty, but the femoral component had been bonded satisfactorily. There have been no other revisions of femoral components. Our findings suggest that the hydroxyapatite coating gives a satisfactory prosthesis-bone interface which is preferable to any other system.
