Physicians' shared decision-making behaviors in attention-deficit/hyperactivity disorder care.

OBJECTIVES
To describe the amount of shared decision-making (SDM) behavior exhibited during treatment-planning encounters for children newly diagnosed as having attention-deficit/hyperactivity disorder and to explore relationships between participant characteristics and the amount of SDM.


DESIGN
Prospective cohort study.


SETTING
Seven community-based primary care pediatric practices in the Cincinnati, Ohio; northern Kentucky; and southeast Indiana regions from October 5, 2009, through August 9, 2010.


PARTICIPANTS
Ten pediatricians and 26 families with a 6- to 10-year-old child newly diagnosed as having attention-deficit/hyperactivity disorder.


OUTCOME MEASURE
The amount of SDM behavior exhibited during videorecorded encounters, as coded by 2 independent raters using the validated Observing Patient Involvement (OPTION) scale, which was adapted for use in pediatric settings and produces a score ranging from 0 (no parental involvement) to 100 (maximal parental involvement).


RESULTS
Treatment decisions focused on initiation of medication treatment. The mean (SD) total OPTION score was 28.5 (11.7). More SDM was observed during encounters involving families with white vs nonwhite children (adjusted mean difference score, 14.9; 95% confidence interval [CI], 10.2-19.6; P < .001), private vs public health insurance coverage (adjusted mean difference score, 15.1; 11.2-19.0; P < .001), mothers with at least some college education vs high school graduate or less (adjusted mean difference score, 12.3; 7.2-17.4; P < .001), and parents who did not screen positive for serious mental illness vs those who did (adjusted mean difference score, 15.0; 11.9-18.1; P < .001).


CONCLUSIONS
Low levels of SDM were observed. Exploratory analyses identified potential disparities and barriers. Interventions may be needed to foster SDM with all parents, especially those of nonwhite race, of lower socioeconomic status, of lower educational level, and with serious mental illness.
A novel therapeutic strategy for turban tumor: scalp excision and combined reconstruction with artificial dermis and split skin graft.

BACKGROUND
Brooke-Spiegler syndrome is a hereditary tumor predisposition disorder characterized by the development of cylindromas, trichoepitheliomas, and spiradenomas. Predilection sites of the disease are hair follicles and sweat glands of the head and neck. In some patients, the tumors can coalesce to so-called turban tumors, which then usually cause cosmetic, psychological, and functional impairment. A curative therapy is not yet available, and thus total scalp excision followed by split skin graft is evolving as a frequently applied therapy. However, this treatment can lead to the formation of a thin and vulnerable skin, which hampers wearing a wig. Therefore, a more robust and functional solution is preferable. Here, we report on a woman with a turban tumor who suffered enormously from the disease and had secluded herself from social life.


METHODS
We treated her with a total scalp excision down to the periosteum, followed by sequential combined reconstruction with an artificial dermal template and split skin grafts.


RESULTS
The treatment resulted in formation of a robust and flexible skin.


CONCLUSION
Treatment of turban tumor is a challenge considering the localization and extensiveness of the tumor masses. This novel therapy for turban tumor leads to a very good cosmetic and functional outcome.
A multimethod, multichannel assessment of affective flattening in schizophrenia

Flat affect was examined across multiple contexts (during interviews and emotional films), multiple channels of expression (facial and vocal), and different assessment techniques (clinical ratings, observational ratings of facial expression, and acoustic analyses) in 23 medication-free schizophrenic patients. Patients participated in three different interviews during which either clinical ratings were made or their voices were audiotaped for later acoustic analyses. Patients were also videotaped while they viewed positive and negative emotional films. The videotapes were then coded for the frequency, intensity, and duration of positive and negative facial expressions. Results indicated that general clinical ratings were related across different interviews. However, only those items specific to affective flattening bore significant relationships to vocal and facial expressiveness. Vocal expressiveness and negative facial expressiveness were related, but vocal expressiveness was not related to positive facial expressiveness.
Generalizing Agile Software Development Life Cycle

In last decade, various agile methods have been introduced and used by software industry. It has been observed that many practitioners are using hybrid of agile methods and traditional methods. The knowledge of agile software development process about the theoretical grounds, applicability in large development settings and connections to establish software engineering disciplines remain mostly in dark. It has been reported that it is difficult for average manager to implement agile method in the organization. Further, every agile method has its own development cycle that brings technological, managerial and environmental changes in organization. A proper roadmap of agile software development in the form of agile software development life cycle can be developed to address the aforesaid issues of agile software development process. Thus, there is strong need of agile software development life cycle that clearly defines the phases included in any agile method and also describes the artifacts of each phase. This generalization of agile software development life cycle provides the guideline for average developers about usability, suitability, applicability of agile methods.

Speech recognition: A model and a program for research

A speech recognition model is proposed in which the transformation from an input speech signal into a sequence of phonemes is carried out largely through an active or feedback process. In this process, patterns are generated internally in the analyzer according to an adaptable sequence of instructions until a best match with the input signal is obtained. Details of the process are given, and the areas where further research is needed are indicated.
Forecasting Stock Market Trend using Prototype Generation Classifiers

Currently, stock price forecasting is carried out using either time series prediction methods or trend classifiers. The trend classifiers are designed to predict the behaviour of stock price’s movement. Recently, soft computing methods, like support vector machines, have shown promising results in the realization of this particular problem. In this paper, we apply several prototype generation classifiers to predict the trend of the NASDAQ Composite index. We demonstrate that prototype generation classifiers outperform support vector machines and neural networks considering the hit ratio of correctly predicted trend directions. Key-Words: Stock price, stock market index, forecasting, prediction, learning vector quantization, prototype generation, support vector machines, neural networks, particle swarm optimization.
Meditation practices for health: state of the research.

OBJECTIVES
To review and synthesize the state of research on a variety of meditation practices, including: the specific meditation practices examined; the research designs employed and the conditions and outcomes examined; the efficacy and effectiveness of different meditation practices for the three most studied conditions; the role of effect modifiers on outcomes; and the effects of meditation on physiological and neuropsychological outcomes.


DATA SOURCES
Comprehensive searches were conducted in 17 electronic databases of medical and psychological literature up to September 2005. Other sources of potentially relevant studies included hand searches, reference tracking, contact with experts, and gray literature searches.


REVIEW METHODS
A Delphi method was used to develop a set of parameters to describe meditation practices. Included studies were comparative, on any meditation practice, had more than 10 adult participants, provided quantitative data on health-related outcomes, and published in English. Two independent reviewers assessed study relevance, extracted the data and assessed the methodological quality of the studies.


RESULTS
Five broad categories of meditation practices were identified (Mantra meditation, Mindfulness meditation, Yoga, Tai Chi, and Qi Gong). Characterization of the universal or supplemental components of meditation practices was precluded by the theoretical and terminological heterogeneity among practices. Evidence on the state of research in meditation practices was provided in 813 predominantly poor-quality studies. The three most studied conditions were hypertension, other cardiovascular diseases, and substance abuse. Sixty-five intervention studies examined the therapeutic effect of meditation practices for these conditions. Meta-analyses based on low-quality studies and small numbers of hypertensive participants showed that TM(R), Qi Gong and Zen Buddhist meditation significantly reduced blood pressure. Yoga helped reduce stress. Yoga was no better than Mindfulness-based Stress Reduction at reducing anxiety in patients with cardiovascular diseases. No results from substance abuse studies could be combined. The role of effect modifiers in meditation practices has been neglected in the scientific literature. The physiological and neuropsychological effects of meditation practices have been evaluated in 312 poor-quality studies. Meta-analyses of results from 55 studies indicated that some meditation practices produced significant changes in healthy participants.


CONCLUSIONS
Many uncertainties surround the practice of meditation. Scientific research on meditation practices does not appear to have a common theoretical perspective and is characterized by poor methodological quality. Firm conclusions on the effects of meditation practices in healthcare cannot be drawn based on the available evidence. Future research on meditation practices must be more rigorous in the design and execution of studies and in the analysis and reporting of results.
OSNR monitoring by deep neural networks trained with asynchronously sampled data

We demonstrate a use of deep neural networks (DNN) for OSNR monitoring with minimum prior knowledge. By using 5-layers DNN trained with 400,000 samples, the DNN successfully estimates OSNR in a 16-GBd DP-QPSK system.
The Relationship between Housing and Health: Children at Risk

In November 2002, the National Center for Healthy Housing convened a 2-day workshop to review the state of knowledge in the field of healthy housing. The workshop, supported with funds from the U.S. Centers for Disease Control and Prevention's National Center for Injury Prevention and Control and National Center for Environmental Health, was unique in that it focused solely on the effect of housing on children's health and the translation of research findings into practical activities in home construction, rehabilitation, and maintenance. Participants included experts and practitioners representing the health, housing, and environmental arenas. Presentations by subject-matter experts covered four key areas: asthma, neurotoxicants, injury, and translational research. Panel discussions followed the presentations, which generated robust dialogue on potential future research opportunities and overall policy gaps. Lack of consensus on standard measurements, incomplete understanding about the interaction of home hazards, inadequate research on the effectiveness of interventions, and insufficient political support limit current efforts to achieve healthy housing. However, change is forthcoming and achievable. Key words: asthma, childhood exposure, environmental toxicants, healthy housing, lead poisoning.
Observer error in grading performance status in cancer patients

 To assess the Karnofsky Performance Status (KPS) scale and the Eastern Cooperative Oncology Group (ECOG) scale with respect to interobserver reliability and interobserver difference between the two scales, 100 consecutive patients in a medical oncology unit were assessed using both scales, which were then given to three independent raters and also to the patients themselves. There was a high level of agreement between most paired assessors. There were three exceptions, which were the RMO/patient and nurse/patient pairs on the KPS scale and the RMO/patient pair on the ECOG scale. The level of agreement was better on the ECOG scale. For individual raters there is no statistical difference between the ECOG and Karnofsky scales. There was good agreement between all raters for both scales. Interobserver variability was less using the ECOG scale. We conclude that either scale could be used with good interobserver reliability. The ECOG scale minimises differences between observers.
Dissemination patterns in non-gastric MALT lymphoma.

BACKGROUND
In contrast to gastric extranodal marginal zone mucosa associated lymphoid tissue (MALT) lymphomas, there is little consensus on the value and clinical consequences of extensive staging at diagnosis and during follow-up in non-gastric MALT lymphomas.


DESIGN AND METHODS
Complete clinical information at presentation and during follow-up was collected for 72 patients with non-gastric MALT lymphoma treated at the Netherlands Cancer Institute between 1977 and 2005. Dissemination patterns at presentation were studied for nine primary dominant organ groups in our series of 72 patients and in a similar cohort treated at Vienna University (for a total of 106 patients).


RESULTS
Twenty-three of our patients (32%) had more than one site of extranodal MALT lymphomatous disease, 13 patients (18%) had regional nodal involvement and 7 (10%) had bone marrow involvement. Site-specific dissemination was seen in paired organs (orbit, lung) and in the gastrointestinal tract (stomach, colon) and primary pulmonary MALT lymphoma was specifically related to gastric involvement (p<0.0001). These patterns of dissemination were retained during relapsed disease.


CONCLUSIONS
Primary extranodal non-gastric marginal zone MALT lymphoma frequently presents as stage IV disease (26%) and multifocal disease (32%) and with a site-specific dissemination pattern. After an extensive staging procedure at presentation, we recommend primary site-directed protocols during follow-up focused on the primary involved tract/organ system, regional lymph nodes and pulmonary and gastric relapses.
What Constitutes Good ICTD Research

The emerging aeld of research that examines the link between information and communication technology and socioeconomic development (ICTD) has been carried forward by researchers mapping methods from their home disciplines onto this new terrain. With this journal logging six years of history (Best & Bar, 2003) and with the third International Conference on Information and Communication Technologies and Development (Dias et al., 2009) behind us, we have arrived at a point where it is worth taking stock of the distinctive challenges we have encountered as a research community. This article intends to propose some common criteria for identifying high-quality and promising research in the aeld, a signiacant challenge in itself, given the diverse range of disciplines involved—from engineering to public policy, from the social sciences to development theory. The seeds of this article were planted in an exchange on a mailing list between its two authors over what standards were truly applicable across disciplinary and methodological distinctions (Toyama & Burrell, 2008). Despite our initial disagreements, we believe that an understanding of interdisciplinary commonalities and differences will inform how ICTD researchers conduct research, how authors write research papers, how they are reviewed, and how conferences and journals select those for publication. Some of these activities require collaboration or evaluation of work across disciplines, and an explicit recognition of their paradigmatic differences could help build bridges between disciplines by allowing disagreements to remain as such. Given the nature of the topic, some disclaimers are in order. First, we emphasize that the ideas put forth in this article will naturally reoect its authors’ particular educational backgrounds, research experiences, and personal perspectives. Burrell’s formal background is in computer science and sociology; Toyama’s in physics and computer science. Thus, our comments apply primarily to what we believe can be said about the disciplines of engineering (including computer science and the various engineering disciplines), the qualitative social sciences (including some, but not all, of anthropology, sociology, etc.), the quantitative social sciences (including some, but not all, of economics, public health, etc.), and aelds with mixed methodologies drawn from the above (including information science, communications research, etc.). Although we have made an attempt to think through what is important in other disciplines (e.g., social theory, public policy), we refrain from claiming to speak for them. With this in mind, we hope that readers will be persuaded by the arguments we present. As with any aeld of study, what work constitutes ICTD and how quality is judged remain open questions to be determined by the community as a whole. It’s a cause for celebration, on the one hand, that such a varied group of people should unite in the quest to understand how technology inter-
Impact of the control of symptomatic paroxysmal atrial fibrillation on health-related quality of life

AIMS
Patients with atrial fibrillation (AF) consider the related symptoms disruptive to their quality of life (QoL). This study aimed to evaluate the impact of the control of symptomatic paroxysmal AF (PAF) on QoL.


METHODS AND RESULTS
Patients with symptomatic PAF were treated for 48 weeks with open-label flecainide acetate controlled release (Flec CR). Quality of life was assessed by SF-36 and Atrial Fibrillation Severity Scale scores at baseline, Week 12 (W12), W24, and W48. Of the 229 treated patients, 217 were analysed for QoL (123 with controlled and 94 with uncontrolled symptomatic PAF at inclusion). The controlled group had a similar or better QoL (SF-36) at baseline compared with a reference population (significantly better for: physical functioning, bodily pain, and physical component). The uncontrolled group had an inferior QoL (significantly worse for: role physical, general health, vitality, role emotional, social functioning, mental health, and mental component). When treated with Flec CR, the controlled group baseline QoL scores were maintained and the uncontrolled group scores were improved to a level comparable to the controlled group scores. Safety findings reflect the known clinical safety profile of flecainide acetate.


CONCLUSION
In this study, patients with uncontrolled symptomatic PAF at baseline had an inferior QoL to those with controlled symptomatic PAF. Following treatment with controlled-release flecainide acetate, their QoL improved to a level comparable to controlled patients.
From the wisdom of crowds to my own judgment in microfinance through online peer-to-peer lending platforms

Information asymmetry is one of the fundamental problems that online peer-to-peer (P2P) lending platforms face. This problem becomes more acute when platforms are used for microfinance, where the targeted customers are mostly economically under-privileged people. Most of the prior empirical studies have been based on data from Prosper.com or similar sites that compete in traditional consumer loan markets. Our study examines P2P lending in microfinance for which borrowers are unbankable so that signals on creditworthiness of new borrowers are very limited. In addition, microfinance customers have more incentive to repeatedly seek loans from the market. Under this microfinance setting, we examine how lenders change their decisions as creditworthiness inference becomes increasingly possible through the accumulation of transaction history. Our findings confirm that lenders seek the wisdom of crowds when information on creditworthiness is extremely limited but switch to their own judgment when more signals are transmitted through the market. Different information sets are utilized according to the structures of decisions. Due to the possibility of a repeated game, it is also shown that borrowers try to maintain a good reputation, and direct communication with lenders may adjust incorrect inference from hard data when their creditworthiness is questioned. 2012 Elsevier B.V.

What Is the Range of Surface Reconstructions from a Gradient Field?

We propose a new technique for edge-suppressing operations on images. We introduce cross projection tensors to achieve affine transformations of gradient fields. We use these tensors, for example, to remove edges in one image based on the edge-information in a second image. Traditionally, edge suppression is acieved by setting image gradients to zero based on thresholds. A common application is in the Retinex problem, where the illumination map is recovered by suppressing the reflectance edges, assuming it is slowly varying. We present a class of problems where edge-suppression can be a useful tool. These problems involve analyzing images of the same scene under variable illumination. Instead of resetting gradients, the key idea in our approach is to derive local tensors using one image and to transform the gradient field of another image using them. Reconstructed image from the modified gradient field shows suppressed edges or textures at the corresponding locations. All operations are local and our approach does not require any global analysis. We demonstrate the algorithm in the context of several applications such as (a) recovering the foreground layer undervarying illumination, (b) estimating intrinsic images in non-Lambertian scenes, (c) removing shadows from color images and obtaining the illumination map, and (d) removing glass relections.
