    Clinical guidelines for the management of rotator cuff disease are not clear. Surgeon surveys in the USA and UK lack agreement regarding surgical indications. Physical examination tests aid surgical decision-making but also lack robust evidence. Study aims were to evaluate: Western Australian orthopaedic surgeons' perceptions about surgical indications; utility of physical examination tests; findings at surgery predictive of outcome and surgeon opinion of a successful surgical outcome. An anonymous rotator cuff survey, previously reported by the American Academy of Orthopaedic Surgeons, was emailed to all surgeons listed with the Australian Orthopaedic Association in Western Australian. Surgeons who treated patients for rotator cuff disease during the previous 12 months were invited to complete the rotator cuff survey and five additional questions were included to capture the above criteria of interest. Within a close community of surgeons based in Western Australia (n = 23) considerable heterogeneity exists in surgical decision-making criteria. A successful surgical outcome was considered to include reduced pain levels, restoration of movement and function and gains in muscle strength. Research is required to inform robust clinical practice guidelines for rotator cuff surgery. Identification of prognostic factors for successful surgical outcome is imperative. © 2017 Royal Australasian College of Surgeons.

    The effect of public opinion on future space programs is discussed in terms of direct support, apathy, or opposition, and concern about the tax burden, budgetary pressures, and national priorities. Factors considered include: the salience and visibility of NASA as compared with other issues, the sources of general pressure on the federal budget which could affect NASA, the public's opinions regarding the size and priority of NASA'S budget, the degree to which the executive can exercise leverage over NASA's budget through influencing or disregarding public opinion, the effects of linkages to other issues on space programs, and the public's general attitudes toward the progress of science.

    Full Text Available Introduction. Hypospadias is a male congenital condition where the opening of the urethral meatus is not located in the typical anatomical position. It has been a challenge for empirical studies to ascertain the level of concordance of opinion among parents and urologists with regard to surgical outcomes according to hypospadias severity. Materials and Methods. Parents of children who had undergone hypospadias repair were recruited for this study (n=104. A set of questionnaires that included some items with Likert scale were created to evaluate postsurgical satisfaction by parents and urologists. SAHLSA-50, a validated instrument for adult Spanish-speaking adults, was used to assess health literacy. Cohen’s Kappa (k coefficient was used to assess inter-observer agreement and Chi Square Goodness of Fit Test was used to determine probability of satisfaction. Findings. Concordance on the level of satisfaction with surgical outcomes for Type cases I was slight (k=0.20; CI 95% 0-0.60, for Type II cases was moderate (k= 0.54; CI 95% 0.13-0.94, and for Type III cases was substantial (k=0.62; CI 95% 0-0.56. However, the probability of satisfaction did not change according to severity (Chi Square Goodness of Fit Test; parents, p=0.84; pediatric urologists, p=0.92. These results cannot be explained by parental health literacy according to SAHLSA-50 test scores. Conclusions. The level of concordance of opinion among parents and urologists with regard to their level of satisfaction with surgical outcomes is related to hypospadias severity, whereby the greatest level of concordance of opinion was achieved among most severe cases. This study underscores the need for longer follow-up to properly assess satisfaction with hypospadias repair, especially for the less severe forms of the condition.

Study Design: Cross-sectional, observational. Place and Duration of Study: Department of Histopathology, Armed Forces Institute of Pathology, Rawalpindi, from April 2006 to May 2007. Materials and Methods: All the cases of soft tissue as well as bone lesions, irrespective of age and gender, which were referred for second opinion or review after being reported elsewhere, were included in the study. A panel of antibodies of soft tissue, epithelial and lymphoid markers was applied according to the requirements of each case. The cases were categorized as category A where there was concurrence between initial diagnosis and diagnosis at review. Category B included cases where there was disagreement in the specific diagnostic entity as per WHO classifications without therapeutic implications. Category C was cases where the category of benign or malignant diagnosis remained the same but there was disagreement in the specific diagnosis with definite therapeutic implications. Category D had diagnosis of benign changed to malignant while category E had cases where diagnosis of malignancy was changed to a benign lesion. Results: During the study period, 34 cases of soft tissue lesions were received for review and second opinion. The mean age of the patients was 39 ΁ 22 years and immunohistochemistry was performed in 21 (62% of 34 cases.

    The purpose of this study was to determine the opinions and expectations of patients and nurses about privacy during a hospital admission for surgery. The study explored what enables and maintains privacy from the perspective of Turkish surgical patients and nurses. The study included 102 adult patients having surgery and 47 nurses caring for them. Data were collected via semistructured questionnaire by face-to-face interviews. The results showed that patients were mostly satisfied by the respect shown to their privacy by the nurses but were less confident of the confidentiality of their personal data. It was found that patients have expectations regarding nursing approaches and attitudes about acknowledging and respecting patient autonomy and confidentiality. It is remarkable that while nurses focused on the physical dimension of privacy, patients focused on informational and psychosocial dimensions of privacy, as well as its physical dimension.

    To analyze the major impact variables in the opinion of nursing staff about the Quality Program of a teaching hospital. An exploratory-descriptive study was performed with 72 nursing staff. Data were collected through self-administered questionnaire containing 24 statements about the Quality Program; and the degree of agreement of the participants was expressed in a Likert scale. The collected data were analyzed by factor analysis and Pearson's correlation coefficient. The analysis grouped the statements in six factors. The Pearson's correlation coefficient defined a scale of influence of the variables within each factor, whose variable with the greatest impact in each factor is the priority issue for improving worker opinion about the Quality Program. The priority variables were to believe the Quality Program contributes to the hospital; to understand the program orientations; interest in hospital quality direction; and do not feel exhausted due to the program. These variables must be focused during the implementation and execution of Quality Program, as they have greater impact on improving opinion regarding the Quality Program and thus helping to increase compliance of the nursing staff to the program.

    Full Text Available Introduction: Orthopaedic surgery is one of the first seven specialties that began collecting Milestone data as part of the Accreditation Council for Graduate Medical Education's Next Accreditation System (NAS rollout. This transition from process-based advancement to outcome-based education is an opportunity to assess resident and faculty understanding of changing paradigms, and opinions about technical skill evaluation. Methods: In a large academic orthopaedic surgery residency program, residents and faculty were anonymously surveyed. A total of 31/32 (97% residents and 29/53 (55% faculty responded to Likert scale assessments and provided open-ended responses. An internal end-of-rotation audit was conducted to assess timeliness of evaluations. A mixed-method analysis was utilized, with nonparametric statistical testing and a constant-comparative qualitative method. Results: There was greater familiarity with the six core competencies than with Milestones or the NAS (p<0.05. A majority of faculty and residents felt that end-of-rotation evaluations were not adequate for surgical skills feedback. Fifty-eight per cent of residents reported that end-of-rotation evaluations were rarely or never filled out in a timely fashion. An internal audit demonstrated that more than 30% of evaluations were completed over a month after rotation end. Qualitative analysis included themes of resident desire for more face-to-face feedback on technical skills after operative cases, and several barriers to more frequent feedback. Discussion: The NAS and outcome-based education have arrived. Residents and faculty need to be educated on this changing paradigm. This transition period is also a window of opportunity to address methods of evaluation and feedback. In our orthopaedic residency, trainees were significantly less satisfied than faculty with the amount of technical and surgical skills feedback being provided to trainees.

    The number of young surgeons in Japan has significantly decreased in recent years, which may lead to future problems in the medical field. Therefore, comprehensive training programs for young surgeons are needed. Retrospective study We developed a specific education program called the "Recruitment of Young Medical Apprentices" (RYOMA) project. We performed this project between January 2008 and August 2013 on fourth- to sixth-year medical students and internship doctors. The RYOMA project included step-by-step surgical education programs on open and scopic procedures as dry, wet, and animal laboratory training. Our goal was to increase the number of young and specialist surgeons. Based on an interview questionnaire answered by 90 medical students, most young students were interested in surgical training and several chose to become surgeons in the future. The most positive opinions regarding the field of surgery were the impressive results achieved with surgery, whereas negative opinions included the difficulty of the surgical skill, physical concerns related to difficult work environments, and the severity of surgical procedures. The present program has begun to resolve negative opinions through adequate training or simulations. Of the 19 medical students and internship doctors who attended the RYOMA project in 2008, 17 trainees (90%) were satisfied with this special surgical program and 16 (88%) showed interest in becoming surgeons. The number of participants considering the field of surgery increased between 2008 and 2013. Of 23 participants, 19 (83%) had a positive opinion of the program after the training. Gaining experience in surgical training from an early stage in medical school and step-by-step authorized education by teaching staff are important for recruiting students and increasing the number of young surgeons.

    Opioid abuse and misuse is a public health crisis. A national effort to reduce this phenomenon is ongoing. Residents represent a large pool of opioid prescribers but, are often not the target for opioid prescribing education (OPE). We developed a survey to assess current opioid prescribing practices and education among surgical residents. An Institutional Review Board and Association of Program Directors in Surgery approved survey was electronically mailed to surgical program directors (PDs). The survey included questions regarding residency type, location, number of graduates per year, perceived value of OPE, residency policy on prescribing outpatients controlled substances, presence of OPE, and preferred method of OPE. A total of 248 PDs were e-mailed the survey with 110 complete responses (44.4%). Of all 104 (94.5%) allow residents to prescribe outpatient opioids with 24 (23.1%) limiting the opioid class prescribed. A total of 29 (27.9%) programs require residents to obtain their own Drug Enforcement Administration registration. Only 22 (20.0%) programs had in place mandatory OPE, 7 (6.4%) PDs were unsure if OPE was a mandatory educational requirement. Furthermore, 70 (79.5%) of programs currently without OPE are considering adding it. Didactic lecture (18, 81.8%) is the most common modality for OPE. The mode time dedicated to OPE was 1 hour. When PDs were asked about which method would be best to deliver OPE, the most common response was case-based scenarios (39, 35.5%). Bivariate statistics were performed and no association was found between OPE and program characteristics'. Most surgical residency programs allow residents to prescribe outpatient opioids, very few require OPE. The most common method of OPE was didactic lectures. To enhance a resident's knowledge in prescribing opioids, programs should incorporate OPE into their curriculum. Copyright © 2017 Association of Program Directors in Surgery.

    The objective of this study was to evaluate whether the Surgical Care Improvement Project (SCIP) improved surgical site infection (SSI) rates using national data at the patient level for both SCIP adherence and SSI occurrence. The SCIP was established in 2006 with the goal of reducing surgical complications by 25% in 2010. National Veterans' Affairs (VA) data from 2005 to 2009 on adherence to 5 SCIP SSI prevention measures were linked to Veterans' Affairs Surgical Quality Improvement Program SSI outcome data. Effect of SCIP adherence and year of surgery on SSI outcome were assessed with logistic regression using generalized estimating equations, adjusting for procedure type and variables known to predict SSI. Correlation between hospital SCIP adherence and SSI rate was assessed using linear regression. There were 60,853 surgeries at 112 VA hospitals analyzed. SCIP adherence ranged from 75% for normothermia to 99% for hair removal and all significantly improved over the study period (P Surgical site infection occurred after 6.2% of surgeries (1.6% for orthopedic surgeries to 11.3% for colorectal surgeries). None of the 5 SCIP measures were significantly associated with lower odds of SSI after adjusting for variables known to predict SSI and procedure type. Year was not associated with SSI (P = 0.71). Hospital SCIP performance was not correlated with hospital SSI rates (r = -0.06, P = 0.54). Adherence to SCIP measures improved whereas risk-adjusted SSI rates remained stable. SCIP adherence was neither associated with a lower SSI rate at the patient level, nor associated with hospital SSI rates. Policies regarding continued SCIP measurement and reporting should be reassessed.

    Computer-assisted surgery (CAS) may allow surgeons to be more precise and minimally invasive, in addition to being an excellent research tool. Medical imaging, such as magnetic resonance and computed tomography is not only an important diagnostic tool, but also a necessary planning tool. In orthopaedic sports medicine, precision is needed when placing tunnels for soft tissue fixation of replacement grafts. Two types of CAS systems -- passive and active -- have been developed. Passive systems, or surgical navigation systems, provide the surgeon with additional information prior to and during the surgical procedure (in real time). Active systems have the ability of performing certain surgical steps autonomously. Both active and passive CAS systems are currently a subject of basic science and clinical investigations and will be discussed and commented on in this article. In summary, passive navigation systems can provide additional information to the surgeon and can therefore lead to more precise tunnel placement. Active robotic technology seems to be accurate and feasible with promising initial results from Europe. However, active and passive CAS can only be as precise as the surgeon who plans the procedure. Therefore, future studies have to focus on integrating, arthroscopy, 3-D image-enhanced computer navigation, and virtual kinematics, as well as to increase precision in surgical techniques.

    Despite increases in medical school enrolment, applications to surgical residency programs in Canada have been in decline over the past decade, with an increasing number of unmatched surgical residency positions. We examined the current status of surgical residency in Canada and analyzed application trends (2002–2013) for surgical training programs across Canada. Our findings suggest that most undergraduate medical schools across Canada are having difficulty fostering interest in surgical careers. We propose that a lack of adequate early exposure to the surgical specialties during undergraduate training is a critical factor. Moving forward, we must examine how the best-performing institutions and surgical programs have maintained interest in pursuing surgical careers and adapt our recruitment methods to both maintain and grow future interest. As Mary Engelbreit said, "If you don't like something, change it; if you can't change it, change the way you think about it."

  10. Aspect-object alignment with Integer Linear Programming in opinion mining.

    Directory of Open Access Journals (Sweden)

    Yanyan Zhao

    Full Text Available Target extraction is an important task in opinion mining. In this task, a complete target consists of an aspect and its corresponding object. However, previous work has always simply regarded the aspect as the target itself and has ignored the important "object" element. Thus, these studies have addressed incomplete targets, which are of limited use for practical applications. This paper proposes a novel and important sentiment analysis task, termed aspect-object alignment, to solve the "object neglect" problem. The objective of this task is to obtain the correct corresponding object for each aspect. We design a two-step framework for this task. We first provide an aspect-object alignment classifier that incorporates three sets of features, namely, the basic, relational, and special target features. However, the objects that are assigned to aspects in a sentence often contradict each other and possess many complicated features that are difficult to incorporate into a classifier. To resolve these conflicts, we impose two types of constraints in the second step: intra-sentence constraints and inter-sentence constraints. These constraints are encoded as linear formulations, and Integer Linear Programming (ILP is used as an inference procedure to obtain a final global decision that is consistent with the constraints. Experiments on a corpus in the camera domain demonstrate that the three feature sets used in the aspect-object alignment classifier are effective in improving its performance. Moreover, the classifier with ILP inference performs better than the classifier without it, thereby illustrating that the two types of constraints that we impose are beneficial.

    Objective To examine the opinions of stakeholders on strategies to improve dietary quality of Supplemental Nutrition Assistance Program (SNAP) participants. Design Participants answered a 38-item web-based survey assessing opinions and perceptions of SNAP and program policy changes. Setting U.S.A. Subjects Survey of 522 individuals with stakeholder interest in the Supplemental Nutrition Assistance Program (SNAP) conducted in October through December 2011. Results The top three barriers to improving dietary quality identified were: 1) unhealthy foods marketed in low-income communities; 2) the high cost of healthy foods; and 3) lifestyle challenges faced by low-income individuals. Many respondents (70%) also disagreed that current SNAP benefit levels were adequate to maintain a healthy diet. Stakeholders believed that vouchers, coupons, or monetary incentives for purchasing healthful foods might have the greatest potential for improving the diets of SNAP participants. Many respondents (78%) agreed that sodas should not be eligible for purchases with SNAP benefits. More than half (55%) believed retailers could easily implement such restrictions. A majority of respondents (58%) agreed that stores should stock a minimum quantity of healthful foods in order to be certified as a SNAP retailer, and most respondents (83%) believed that the USDA should collect data on the foods purchased with SNAP benefits. Conclusions Results suggest that there is broad stakeholder support for policies that align SNAP purchase eligibility with national public health goals of reducing food insecurity, improving nutrition and preventing obesity.

    2011-09-01

    Changing realities in surgery and surgical technique have heightened the need for agile adaptation in training programs. Current guidelines reflect the growing acceptance and adoption of the use of minimally invasive surgery (MIS) in oncology. North American general surgery residents are often not adequately skilled in advanced laparoscopic surgery skills at the completion of their residency. Presently, advanced laparoscopic surgery training during surgical oncology fellowship training occurs on an ad-hoc basis in many surgical oncology programs. We present a rational and template for a structured training in advanced minimally invasive surgical techniques during surgical oncology fellowship training. The structure of the program seeks to incorporate evidence-based strategies in MIS training from a comprehensive review of the literature, while maintaining essential elements of rigorous surgical oncology training. Fellows in this stream will train and certify in the Fundamentals of Laparoscopic Surgery (FLS) course. Fellows will participate in the didactic oncology seminar series continuously throughout the 27 months training period. Fellows will complete one full year of dedicated MIS training, followed by 15 months of surgical oncology training. Minimal standards for case volume will be expected for MIS cases and training will be tailored to meet the career goals of the fellows. We propose that a formalized MIS-Surgical Oncology Fellowship will allow trainees to benefit from an effective training curriculum and furthermore, that will allow for graduates to lead in a cancer surgery milieu increasingly focused on minimally invasive approaches.

    The aim of this study was to evaluate the awareness and perception of general educated Indian individuals about Doctor of Pharmacy course. A cross-sectional structured Pharm.D questionnaire survey was conducted at educational institutions of India mainly through e-mails. Pharm.D questionnaire survey was conducted over a period of six months. The questionnaire was classified into four major categories, including course-related questions, roles-related questions, critical comparative questions, and opinion-based questions. The responses were collected and analyzed to assess the opinions and attitudes of the study population regarding the course Pharm.D. Out of 2819 responses, 66.01% agreed that Indian syllabus, teaching procedure, and hospital training in institutions are enough to prepare an ideally graduated Pharm.D. Respondents of about 70.59% agreed that Pharm.Ds should take care of complete responsibility of drug therapy rather than physicians prescribing the medications and Pharm.Ds fixing the dose. The statement "Pharm.Ds play a vital role in improving medication adherence through patient counseling" was accepted by 47.80%, whereas 41.40% did not accept it as they felt that the Pharm.D's role in this regard is not more than the physician's role, and 10.80% suggested that other healthcare professionals would play a better role. Among all the respondents, 73.64% of the study population was found to be ready for giving equal credit and respect to Pharm.Ds as physicians. Our survey emphasizes on the opinion of educated people of having Pharm.Ds in both government and private hospitals to take care of complete therapy and for improving medication adherence.

    Methods used to select opinion leaders for informal behavior change interventions vary, affecting the role they adopt and the outcomes of interventions. The development of successful identification methods requires evidence that these methods achieve their aims. This study explored whether the "whole community" nomination process used in the ASSIST smoking prevention program successfully identified "peer supporters" who were well placed within their school social networks to diffuse an antismoking message to their peers. Data were collected in the United Kingdom during A Stop Smoking in Schools Trial. Behavioral data were provided at baseline and post intervention by all students. Social network data were provided post intervention by students in four control and six intervention schools. Centrality measures calculated using UCINET demonstrate that the ASSIST nomination process successfully identified peer supporters who were more socially connected than others in their year and who had social connections across the entire year group including the program's target group. The results indicate that three simple questions can identify individuals who are held in high esteem by their year group and who also have the interpersonal networks required of opinion leaders to successfully disseminate smoke-free messages through their social networks. This approach could be used in other informal health promotion initiatives.

    There is pressure for surgical departments to introduce new and innovative health technologies in an evidence-based manner while ensuring that they are safe and effective and can be managed with available resources. A local health technology assessment (HTA) program was developed to systematically integrate research evidence with local operational management information and to make recommendations for subsequent decision by the departmental executive committee about whether and under what conditions the technology will be used. The authors present a retrospective analysis of the outcomes of this program as used by the Department of Surgery & Surgical Services in the Calgary Health Region over a 5-year period from December 2005 to December 2010. Of the 68 technologies requested, 15 applications were incomplete and dropped, 12 were approved, 3 were approved for a single case on an urgent/emergent basis, 21 were approved for "clinical audit" for a restricted number of cases with outcomes review, 14 were approved for research use only, and 3 were referred to additional review bodies. Subsequent outcome reports resulted in at least 5 technologies being dropped for failure to perform. Decisions based on local HTA program recommendations were rarely "yes" or "no." Rather, many technologies were given restricted approval with full approval contingent on satisfying certain conditions such as clinical outcomes review, training protocol development, or funding. Thus, innovation could be supported while ensuring safety and effectiveness. This local HTA program can be adapted to a variety of settings and can help bridge the gap between evidence and practice.

    Background: Arts in medicine programs have significant impacts on patients and staff in long-term care environments, but the literature lacks evidence of effectiveness on hospital units with shorter average lengths of stay. Methods: The qualitative study used individual structured interviews to assess the impacts of arts programming on job satisfaction, stress, unit culture, support, quality of care, and patient outcomes on a short-term medical-surgical unit, and used a qualitative cross comparison grounded theory methodology to analyze data. Results: The study confirmed that arts programming can positively affect unit culture, nursing practice, and quality of care on short-stay medical-surgical units. Significant insights related to nursing practice and the art program were found, including that music can cause negative distraction for staff. Conclusions: While positive impacts of arts programming on the medical-surgical environment are clear, potential negative effects also need to be considered in the development of practice protocols for artists.

    This project aimed at documenting the surgical training curricula offered by North American graduate periodontics programs. A survey consisting of questions on teaching methods employed and the content of the surgical training program was mailed to directors of all fifty-eight graduate periodontics programs in Canada and the United States. The chi-square test was used to assess whether the residents' clinical experience was significantly (Pperiodontal plastic procedures, hard tissue grafts, and implants. Furthermore, residents in programs offering a structured preclinical component performed significantly more procedures (P=0.012) using lasers than those in programs not offering a structured preclinical program. Devising new and innovative teaching methods is a clear avenue for future development in North American graduate periodontics programs.

    Principal Recipients (PRs) receive money from the Global Fund to fight AIDS, Tuberculosis and Malaria (Global Fund) to manage and implement programs. However, little research has gone into understanding their opinions and experiences. This survey set out to describe these, thereby providing a baseline against which changes in PR opinions and experiences can be assessed as the recently introduced new funding model is rolled out. An internet based questionnaire was administered to 315 PRs. A total of 115 responded from 69 countries in Africa, Asia, Eastern Europe and Latin America. The study was conducted between September and December 2012. Three quarters of PRs thought the progress update and disbursement request (PU/DR) system was a useful method of reporting grant progress. However, most felt that the grant negotiation processes were complicated, and that the grant rating system did not reflect performance.While nearly all PRs were happy with the work being done by sub-Recipients (92%) and Fund Portfolio Managers (86%), fewer were happy with the Office of the Inspector General (OIG). Non-government PRs were generally less happy with the OIG's work compared to government PRs.Most PRs thought the Global Fund's Voluntary Pooled Procurement system made procurement easier. However, only 29% said the system should be made compulsory.When asked which aspects of the Global Fund's operations needed improvement, most PRs said that the Fund should re-define and clarify the roles of different actors, minimize staff turnover at its Secretariat, and shorten the grant application and approval processes. All these are currently being addressed, either directly or indirectly, under a new funding model. Vigorous assessments should nonetheless follow the roll-out of the new model to ensure the areas that are most likely to affect PR performance realize sustained improvement. Opinions and experiences with the Global Fund were varied, with PRs having good communication with Fund

    Full Text Available Background. Humanitarian medical missions may be an effective way to temporarily overcome limitations and promote long-term solutions in the local health care system. Operation Smile, an international medical not-for-profit organization that provides surgery for patients with cleft lip and palate, not only provides surgery through short-term international missions but also focuses on developing local capacity. Methods. The history of Operation Smile was evaluated globally, and then on a local level in 3 countries: Colombia, Bolivia, and Ethiopia. Historical data was assessed by two-pronged success of (1 treating the surgical need presented by cleft patients and (2 advancing the local capacity to provide primary and ongoing care to patients. Results. The number of patients treated by Operation Smile has continually increased. Though it began by using only international teams to provide care, by 2012, this had shifted to 33% of patients being treated by international teams, while the other 67% received treatment from local models of care. The highest level of sustainability was achieved in Columbia, where two permanent centers have been established, followed by Bolivia and lastly Ethiopia. Conclusions. International missions have value because of the patients that receive surgery and the local sustainable models of care that they promote.

    Full Text Available In real life, information available for certain situations is vague and such uncertainty is unavoidable. One possible solution is to consider the knowledge of experts on the parameters involved as intuitionistic fuzzy data. We examine a linear programming problem in which all the coefficients are intuitionistic in nature. An approach is presented to solve an intuitionistic fuzzy linear programming problem. In this proposed approach, a procedure for allocating limited resources effectively among competing demands is developed. An example is given to highlight the illustrated study.

    Material and Method: A total of 170 family physicians working in Kahramanmaras were included in the study. After obtaining informed consent a questionnaire comprising questions regarding socio-demographic properties, conveying contracted family physicians as family medicine specialists and organization of the training program was applied to participants. Results: Among physicians participating in the study 130 (76.5% were male and 40 (23.5% were female, with a mean age of 40.7±7.1 (min = 26 years, max = 64 years. The mean duration of professional experience of physicians was 15.3±7.0 (min = 2 years, max = 40 years years. Of all, 91 (53.5% participants had already read the decree on family medicine specialist training program for contracted family physicians. A hundred and fifteen (67.6% family physicians supported that Family Medicine Specialty program should be taken part-time without interrupting routine medical tasks. Only 51 (30.0% participants stated the requirement of an entrance examination (TUS for family medicine specialty training. Conclusion: Family medicine specialty training program towards family physicians should be considered in the light of scientific criteria. In family medicine, an area exhibited a holistic approach to the patient; specialty training should be through residency training instead of an education program. For this purpose, family medicine departments in medical faculties should play an active role in this process. Additionally further rotations in needed branches should be implemented with a revision of area should be performed. In medicine practical training is of high importance and distant or part-time education is not appropriate, and specialist training shall be planned in accordance with the medical specialty training regulations.

    The objective is to establish the duration of our interventions, intermediate times and surgical performance. This will create a virtual waiting list to apply a mathematical programme that performs programming with maximum performance. Retrospective review of 49 surgical sessions obtaining the delay in start time, intermediate time and surgical performance. Retrospective review of 4,045 interventions performed in the last 3 years to obtain the average duration of each type of surgery. Creation of a virtual waiting list of 700 patients in order to perform virtual programming through the MIQCP-P until achieving optimal performance. Our surgical performance with manual programming was 75.9%, ending 22.4% later than 3pm. The performance in the days without suspensions was 78.4%. The delay at start time was 9.7min. The optimum performance was 77.5% with a confidence of finishing before 15h of 80.6%. The waiting list has been scheduled in 254 sessions. Our manual surgical performance without suspensions (78.4%) was superior to the optimal (77.5%), generating days finished later than 3pm and suspensions. The possibilities for improvement are to achieve punctuality at the start time and adjust the schedule to the ideal performance. The virtual programming has allowed us to obtain our ideal performance and to establish the number of operating rooms necessary to solve the waiting list created. The data obtained in virtual mathematical programming are reliable enough to implement this model with guarantees. Copyright © 2017 SECOT. Publicado por Elsevier España, S.L.U. All rights reserved.

    Operating room (OR) efficiency continues to be a high priority for hospitals. In this context the concept of benchmarking has gained increasing importance as a means to improve OR performance. The aim of this study was to investigate whether and how participation in a benchmarking and reporting program for surgical process data was associated with a change in OR efficiency, measured through raw utilization, turnover times, and first-case tardiness. The main analysis is based on panel data from 202 surgical departments in German hospitals, which were derived from the largest database for surgical process data in Germany. Panel regression modelling was applied. Results revealed no clear and univocal trend of participation in a benchmarking and reporting program for surgical process data. The largest trend was observed for first-case tardiness. In contrast to expectations, turnover times showed a generally increasing trend during participation. For raw utilization no clear and statistically significant trend could be evidenced. Subgroup analyses revealed differences in effects across different hospital types and department specialties. Participation in a benchmarking and reporting program and thus the availability of reliable, timely and detailed analysis tools to support the OR management seemed to be correlated especially with an increase in the timeliness of staff members regarding first-case starts. The increasing trend in turnover time revealed the absence of effective strategies to improve this aspect of OR efficiency in German hospitals and could have meaningful consequences for the medium- and long-run capacity planning in the OR.

    The purpose of this study was to assess residents' perspectives on their implant surgical training in Advanced Education in Prosthodontic programs in the United States. Questionnaires were distributed to all prosthodontic residents (N = 442). The 27 questions assessed the subjective and objective aspects of implant surgical training from the view of prosthodontic residents. The data were compiled and reported as frequencies. Descriptive statistics were used to analyze the data. One hundred and ninety-eight responses (44.8%) were received and analyzed. Forty-seven percent (94) of the respondents felt that the philosophy of their programs regarding implant placement in prosthodontics was "optional but encouraged," whereas 30% (60) felt that it was "mandatory." The majority of the respondents (73%, 144) stated that their programs allowed them to place implants for their own patients. For those respondents who placed their own implants, 40% (58) of them indicated that the level of their clinical training was "competent." Almost half of the respondents expressed that they would like to have a proficient level of clinical training in implant surgery by the completion of their residency programs. Forty-four percent (87) of the respondents felt their residency training adequately prepared them for implant surgery, whereas the other 37% (73) did not. For those who did not, 74% (55) felt their residency programs should have prepared them for implant surgical training. The current generation of prosthodontic residents has an opportunity to place implants in their programs and would like to be trained in surgical aspects of implant dentistry at the level of competency or higher. © 2010 by The American College of Prosthodontists.

    2010-08-01

    This cross-sectional study was designed to document the methods utilized by North American graduate periodontics programs in assessing their residents' surgical skills. A survey of clinical skills assessment was mailed to directors of all fifty-eight graduate periodontics programs in Canada and the United States. Thirty-four programs (59 percent) responded. The data collected were analyzed using SPSS version 15.0. The results demonstrate that the most common practice for providing feedback and documenting residents' surgical skills in the programs surveyed was daily one-on-one verbal feedback given by an instructor. The next two most commonly reported methods were a standard checklist developed at program level and a combination of a checklist and verbal comments. The majority of the programs reported that the instructors met collectively once per term to evaluate the residents' progress. The results suggest that graduate periodontics programs provide their residents frequent opportunities for daily practice with verbal feedback from instructors. However, assessment strategies identified in other health professions as beneficial in fostering the integration of clinical skills practices are not employed.

    The purpose of this study was to determine the incidence and predictors of nonverifiable research publications among applicants to a trauma and surgical critical care fellowship program. All complete applications submitted to our trauma and surgical critical care fellowship program were prospectively collected for 4 application cycles (2009 to 2012). All publications listed by applicants were tabulated and underwent verification using MEDLINE and direct journal search with verification by a team of professional health sciences librarians. Demographics and academic criteria were compared between applicants with nonverifiable and verifiable publications. A total of 100 applicants reported 301 publications. Of those, 20 applicants (20%) listed 32 papers (11%) that could not be verified. These applicants comprised 30% of those with 1 or more peer-reviewed publications. There were no significant differences in sex (male, 55% nonverifiable vs 60% verifiable, p = 0.684) or age (34.3 ± 6.6 years vs 34.2 ± 5.0 years, p = 0.963). There were no differences with regard to citizenship status (foreign medical graduates, 20% nonverifiable vs 28% verifiable, p = 0.495). Applicants with nonverified publications were less likely to be in the military (0% vs 14%, p = 0.079), more likely to have presented their work at surgical meetings (80% vs 58%, p = 0.064), and to be individuals with 3 or more peer-reviewed publications (55% vs 25%, p = 0.009). In this analysis of academic integrity, one-fifth of all applicants applying to a trauma and surgical critical care fellowship program and 30% of those with 1 or more peer-reviewed publications had nonverifiable publications listed in their curricula vitae. These applicants were less likely to be in the military, more likely to have presented their work at surgical meetings and to have 3 or more peer-reviewed publications.

    Surveillance of surgical site infections (SSI) is a priority. One of the fundamental principles for the surveillance of SSI is based on receiving effective field feedback (retro-information). The aim of this study was to report the results of a program of SSI surveillance and validate the hypothesis that there is a correlation between creating a SSI surveillance program and a reduction in SSI. The protocol was based on the weekly collection of surveillance data obtained directly from the different information systems in different departments. A delay of 3 months was established before extraction and analysis of data and information from the surgical teams. The NNIS index (National Nosocomial Infections Surveillance System) developed by the American surveillance system and the reduction of length of hospital stay index Journées d'hospitalisation évitées (JHE). Since the end of 2009, 7156 surgical procedures were evaluated (rate of inclusion 97.3%), and 84 SSI were registered with a significant decrease over time from 1.86% to 0.66%. A total of 418 days of hospitalization have been saved since the beginning of the surveillance system. Our surveillance system has three strong points: follow-up is continuous, specifically adapted to orthopedic traumatology and nearly exhaustive. The extraction of data directly from hospital information systems effectively improves the collection of data on surgical procedures. The implementation of a SSI surveillance protocol reduces SSI.

    This special article provides an introduction to the World Health Organization (WHO) Emergency and Essential Surgical Care (EESC) program. The program was launched by the WHO in December of 2005 to address the lack of adequate surgical capacity as a global public health issue. The overall objective is to reduce death and disability from trauma, burns, pregnancy-related complications, domestic violence, disasters, and other surgically treatable conditions. The program and materials have spread to over 35 countries and focus on providing (1) basic education and training materials; (2) enhancement of surgical infrastructure at the governmental and health facility level; and (3) resources for monitoring and evaluating surgical, obstetrical, and anesthetic capacity. Additionally, a global forum for program members was established that collaborates with ministries of health, WHO country offices, nongovernmental organizations, and academia. The results of the third biennial meeting of global EESC members in Mongolia are outlined as well as future challenges.

    There has been a long-standing desire to implement a multi-institutional, multispecialty program to address surgical quality improvement for children. This report documents results of the initial phase of the American College of Surgeons National Surgical Quality Improvement Program Pediatric. From October 2008 to December 2009, patients from 4 pediatric referral centers were sampled using American College of Surgeons National Surgical Quality Improvement Program methodology tailored to children. A total of 7,287 patients were sampled, representing general/thoracic surgery (n = 2,237; 30.7%), otolaryngology (n = 1,687; 23.2%), orthopaedic surgery (n = 1,367; 18.8%), urology (n = 893; 12.3%), neurosurgery (n = 697; 9.6%), and plastic surgery (n = 406; 5.6%). Overall mortality rate detected was 0.3% and 287 (3.9%) patients had postoperative occurrences. After accounting for demographic, preoperative, and operative factors, occurrences were 4 times more likely in those undergoing inpatient versus outpatient procedures (odds ratio [OR] = 4.71; 95% CI, 3.01-7.35). Other factors associated with higher likelihood of postoperative occurrences included nutritional/immune history, such as preoperative weight loss/chronic steroid use (OR = 1.49; 95% CI, 1.03-2.15), as well as physiologic compromise, such as sepsis/inotrope use before surgery (OR = 1.68; 95% CI, 1.10-1.95). Operative factors associated with occurrences included multiple procedures under the same anesthetic (OR = 1.58; 95% CI, 1.21-2.06) and American Society of Anesthesiologists classification category 4/5 versus 1 (OR = 5.74; 95% CI, 2.94-11.24). Specialty complication rates varied from 1.5% for otolaryngology to 9.0% for neurosurgery (p Pediatric has the potential to identify outcomes of children's surgical care that can be targeted for quality improvement efforts.

    The goal of simulation-based medical education and training is to help trainees acquire and refine the technical and cognitive skills necessary to perform clinical procedures. When designers incorporate simulation into programs, their efforts should be in line with training needs, rather than technology. Designers of simulation-augmented surgical training programs, however, face particular problems related to identifying a framework that guides the curricular design activity to fulfill the particular requirements of such training programs. These problems include the lack of (1) an objective identification of training needs, (2) a systematic design methodology to match training objectives with simulation resources, (3) structured assessments of performance, and (4) a research-centered view to evaluate and validate systematically the educational effectiveness of the program. In this report, we present a process called "Aim - FineTune - FollowThrough" to enable the connection of the identified problems to solutions, using frameworks from psychology, motor learning, education and experimental design.

    The impact of early medical school mentorship in students' clerkships performance and career selection is unknown. We administered Introduction to Surgery, a resident-directed, semester-long, preclinical elective to junior medical students who answered a Likert-type survey after residency application. Elective participants (EPs) were compared with nonparticipant applicants (EAs), medical school class (MS), and national match outcomes (USA). All 18 EPs (7 M1's, 11 M2's) completed the elective and survey. EP reported more confidence and improved surgical skills, especially attributed to resident mentorship (F(13,237) = 2.3, P = 8*10(-3)). EP "honored" the clerkship more than MS (P = .05); 55.6% of EP, 37.5% of EA, and 27.7% of MS chose surgical fields, yielding a relative risk of 2.0 for EP vs MS (95% confidence interval: 1.3 to 3.2, P = 4*10(-3)). EP "strongly agree" with future mentorship programs (4.6/5), and 1 EP reported the course to be the "main reason" for applying to general surgery. Introduction to Surgery provides a model for a multifaceted junior medical student mentorship program, which has the potential to retain interested students for surgical career selection.

    Background Robotic-assisted surgery has potential benefits over laparoscopy yet little has been published on the integration of this platform into complex surgical oncology. We describe the outcomes associated with integration of robotics into a large surgical oncology program, focusing on metrics of safety and efficiency. Methods A retrospective review of a prospectively maintained database of robotic procedures from July 2009 to October 2014 identifying trends in volume, operative time, complications, conversion to open, and 90-day mortality. Results Fourteen surgeons performed 1236 cases during the study period: thyroid (246), pancreas/duodenum (458), liver (157), stomach (56), colorectal (129), adrenal (38), cholecystectomy (102), and other (48). There were 38 conversions to open (3.1%), 230 complications (18.6%), and 13 mortalities (1.1%). From 2009 to 2014, operative volume increased (7 cases/month vs 24 cases/month; P robotic surgical oncology program utilizing multiple surgeons is safe and feasible. As operative volume increased, operative time, complications, and conversions to open decreased and plateaued at approximately 3 years. No unanticipated adverse events attributable to the introduction of this platform were observed.

  2. The impact on hospitals of reducing surgical complications suggests many will need shared savings programs with payers.

    Reducing the complications that patients experience following surgery has garnered renewed attention from the medical and policy community. Reducing surgical complications is, foremost, critically important for patients. Moreover, in a competitive environment increasingly characterized by transparency of outcomes, the surgical complication rate is an important measure of hospital performance that could strongly influence choices of care and care sites made by patients and payers. However, programs to achieve such improvements can reduce hospital revenues, as reimbursements to treat patients for complications decrease. In this article we examine the business case for hospitals' consideration of programs to reduce surgical complications. We found that if a hospital's surgical inpatient volume is not growing, such a program results in negative cash flow. We also found that if a hospital's surgical volume is growing, and if the hospital can sufficiently reduce the average length-of-stay for surgical patients without complications, the cash flow could be positive. We recommend that hospitals with limited growth prospects that are nonetheless contemplating a surgical complication reduction program establish agreements with payers to share in any savings generated by the program.

    The National Surgical Quality Improvement Program (NSQIP) of the American College of Surgeons provides risk-adjusted surgical outcome measures for participating hospitals that can be used for performance improvement of surgical mortality and morbidity. A surgical clinical nurse reviewer collects 135 clinical variables including preoperative risk factors, intraoperative variables, and 30-day postoperative mortality and morbidity outcomes for patients undergoing major surgical procedures. A report on mortality and complications is prepared twice a year. This article summarizes briefly the history of NSQIP and how its report on surgical outcomes can be used for performance improvement within a hospital system. In particular, it describes how to drive performance improvement with NSQIP data using the example of postoperative respiratory complications--a major factor of postoperative mortality. In addition, this article explains the benefit of a collaborative of several participating NSQIP hospitals and describes how to develop a "playbook" on the basis of an outcome improvement project.

    Wolfe, Elizabeth S; Bryant, Elizabeth A

    The American College of Surgeons (ACS) mandates that each verified trauma center must have an injury prevention coordinator (IPC); however, Chapter 18 in the Resources for Optimal Care of the Injured Patient (2014) provides minimal information on how to effectively lead or manage an injury prevention (IP) program. This opinion article addresses 3 fundamental components of an effective IP program: (1) construction of an innovative vision of IP programming using current technology; (2) intentional investment and involvement; and (3) stakeholder leadership, engagement, and sustainability. This article also provides leadership and management methods from other professions both within and outside of the health care field that can be translated into sustainable IP program planning, implementation, and longevity.

    Continuous body growth and rigidity of scars in children are significant contributors to burn scar contractures (BSCs). BSCs decrease a patient's range of motion and their ability to perform activities of daily living. A benefit of exercise is an increase the patient's ability to perform and sustain activities of daily living. Therefore, we investigated whether patients who were involved in a supervised, hospital-based exercise program, in addition to physical and occupational therapy (PTEX), would have fewer surgical interventions than a nonexercise group receiving home-delivered physical and occupational therapy (PT) alone. We examined 53 patients at 6, 9, 12, 18, and 24 months postburn. The PTEX group (n = 27) completed a 12-week supervised exercise program starting at 6 months postburn. Exercise sessions were held three times per week, with duration of 60 to 90 minutes per session. Resistance and aerobic exercises were performed at 70 to 85% of the patient's maximal effort. In contrast, the PT group (n = 26) received a home rehabilitation program with no supervised exercise. Patients were evaluated at 3-month intervals for scar formation, range of motion, and need for surgery. At 12, 18, 24 months postburn, the number of patients in the PTEX group needing release of BSC was significantly lower than the number of patients in the PT group. The results indicate that patients would receive a significant benefit if enrolled in a supervised exercise and physiotherapy program with the exercise portion consisting of an aerobic and resistance-training component. This type of program is beneficial in decreasing the number of surgical interventions and should be incorporated as part of a postburn outpatient rehabilitation.

    Researchers conducted an evaluation of participants' perceptions of a dropout prevention program - the NBA High School program - involving a National Basketball Association (NBA) team, a high school located in downtown [City], and the College of Education (COE) at the local State University (SU). The program targeted "at-risk" high school students while utilizing student-teachers as tutors and mentors. Researchers utilized mixed methods to assess student, student-teacher, and high school teacher participants' experiences with and opinions of the program. Researchers found (1) students enjoyed the program, especially given the involvement of the student-teachers; (2) students believed the program helped improve their grades; (3) student-teachers enjoyed working with their students, although student-teachers found some of the expectations surrounding their positions and roles as tutors/mentors within the high school to be unclear and frustrating; (4) high school teachers felt significantly better about the program than the student-teachers; and (5) overall, all sets of respondents categorically supported the program and its benefits. Findings indicated that the involvement of mentors or role models matters to students, and clear and organized logistics, planning, and communication are integral for program success.

National data on the assessment of technical skills during surgical training are lacking. We conducted this study to document the assessment tools for technical skills currently used in different surgical specialties, their relationship with remediation, the recommended tools from the program directors’ perspective, and program directors’ attitudes toward the available objective tools to assess technical skills.Methods: This study was a cross-sectional survey of surgical program directors (PDs. The survey was initially developed using a focus group and was then sent to 116 PDs. The survey contains demographic information about the program, the objective assessment tools used, and the reason for not using assessment tools. The last section discusses the recommended tools to be used from the PDs’ perspective and the PDs’ attitude and motivation to apply these tools in each program.

    Full Text Available Abstract Background Despite conflicting results after surgically treated ankle fractures few studies have evaluated the effects of different types of training programs performed after plaster removal. The aim of this study was to evaluate the effects of a 12-week standardised but individually suited training program (training group versus usual care (control group after plaster removal in adults with surgically treated ankle fractures. Methods In total, 110 men and women, 18-64 years of age, with surgically treated ankle fracture were included and randomised to either a 12-week training program or to a control group. Six and twelve months after the injury the subjects were examined by the same physiotherapist who was blinded to the treatment group. The main outcome measure was the Olerud-Molander Ankle Score (OMAS which rates symptoms and subjectively scored function. Secondary outcome measures were: quality of life (SF-36, timed walking tests, ankle mobility tests, muscle strength tests and radiological status. Results 52 patients were randomised to the training group and 58 to the control group. Five patients dropped out before the six-month follow-up resulting in 50 patients in the training group and 55 in the control group. Nine patients dropped out between the six- and twelve-month follow-up resulting in 48 patients in both groups. When analysing the results in a mixed model analysis on repeated measures including interaction between age-group and treatment effect the training group demonstrated significantly improved results compared to the control group in subjects younger than 40 years of age regarding OMAS (p = 0.028, muscle strength in the plantar flexors (p = 0.029 and dorsiflexors (p = 0.030. Conclusion The results of this study suggest that when adjusting for interaction between age-group and treatment effect the training model employed in this study was superior to usual care in patients under the age of 40.

The objectives of this study are to assess the opinions of the surgical residents of the likely effects of the advent of MAS on their surgical training, and to record any solutions that they may propose. Material and Methods: A survey of 17 questions (13 closed, 2 open and 1 mixed was administered to 72 residents training in seven of the surgical specialties that participate at the MAS Unit at the Hospital San Carlos, Madrid. Results: The survey was completed by 36.1% of residents. All those that responded considered that: 1 familiarity with, and training in, this type of surgery is important . 2 the surgical techniques performed at the Hospital’s MAS Unit are fundamental for the surgical training of the resident. 3 Major Ambulatory Surgery should be included in the training of surgical residents. 80.8% consider that receiving MAS training will improve their employment prospects on finishing their residence period. Conclusions: Residents consider that their participation in the activity of MAS Units is important and that well-structured, well-coordinated programs are required. All parties involved should participate in the preparation of the programs, which should be adapted to the characteristics of each specialty.

    The U.S. Department of Energy (DOE) Hydrogen Program focuses on overcoming critical barriers to the widespread use of hydrogen fuel cell technology. The transition to a new, hydrogen-based energy economy requires an educated human infrastructure. With this in mind, the DOE Hydrogen Program conducted statistical surveys to measure and establish baselines for understanding and awareness about hydrogen, fuel cells, and a hydrogen economy. The baseline data will serve as a reference in designing an education program, and it will be used in comparisons with future survey results (2008 and 2011) to measure changes in understanding and awareness. Scientific sampling was used to survey four populations: (1) the general public, ages 18 and over; (2) students, ages 12-17; (3) state and local government officials; and (4) potential large-scale hydrogen users. It was decided that the survey design should include about 1,000 individuals in each of the general public and student categories, about 250 state and local officials, and almost 100 large-scale end users. The survey questions were designed to accomplish specific objectives. Technical questions measured technical understanding and awareness of hydrogen technology. Opinion questions measured attitudes about safety, cost, the environment, and convenience, as well as the likelihood of future applications of hydrogen technology. For most of the questions, "I don't know" or "I have no opinion" were acceptable answers. Questions about information sources assessed how energy technology information is received. The General Public and Student Survey samples were selected by random digit dialing. Potential large-scale end users were selected by random sampling. The State and Local Government Survey was of the entire targeted population of government officials (not a random sample). All four surveys were administered by computer-assisted telephone interviewing (CATI). For each population, the length of the survey was less than

    Colorectal surgery is associated with high rates of surgical site infection (SSI). The National Surgery Quality Improvement Program is a validated, risk-adjusted quality-improvement program for surgical patients. Patient stratification and risk adjustment are associated with Current Procedural Terminology codes and primary disease diagnosis is not considered. Our aim was to determine the association between disease diagnosis and SSI rates. Data from all 2009 National Surgery Quality Improvement Program institutions were analyzed. ICD-9 codes were used to differentiate patients into cancer (colon or rectal), ulcerative colitis, regional enteritis, diverticular disease, and others. Diagnosis-specific SSI rates were compared with benign neoplasm, which had the lowest rate (8.9%). Logistic regression was performed adjusting for age, body mass index, American Society of Anesthesiologists classification, wound type, and relative value unit. There were 24,673 colorectal procedures, with 1,956 superficial incisional (SSSI), 398 deep incisional (DSSI), and 1,096 organ/space (O/SSSI) infections. Odds ratio (OR) and 95% confidence intervals compared with benign neoplasm diagnosis were computed after adjustment for each diagnosis category. In rectal cancer patients, significantly more SSSI (OR = 1.6; 95% CI, 1.3-2.1; p SSI type is associated with the underlying disease diagnosis. To facilitate colorectal SSI-reduction efforts, the disease process must be considered to design appropriate interventions. In addition, institutional comparisons based on aggregate or stratified SSI rates can be misleading if the colorectal disease mix is not considered. Copyright © 2012 American College of Surgeons.

    This opinion-based article aims to highlight the worrying decline in support for dental public health as a specialty. Not only is this specialty important for its role in commissioning services, it is crucial for the identification of vulnerable groups in society and ensuring dental services are acceptable and assessable for these populations. Dental public health also addresses the social determinants of health in its approach, acknowledging the impact of these in perpetuating inequalities and looking for multisectoral approaches to their management. This article also looks at the lack of appreciation for these determinants in dental foundation training and how a change in the structure of the programme could both address this and the current shortage of places.

    The medical record not only stores information on actions taken regarding patient care but it is also a source of education for those who read it. Nurses, residents, interns, students and consulting clinicians look to the medical record to gain an understanding of clinical disease and the diagnostic studies and treatment regimens used to affect the disease. We have presented our initial findings and our framework for developing and evaluating The Surgical Illustrator, a software program that will enable clinicians to include in EMRs information that is usually hand drawn in traditional medical records. The future of the EMR will be a direct result of research and development devoted to creating innovative means of conveying clinically pertinent data. Our goal is to make a major contribution to this effort.

    Background The Hospital Value-Based Purchasing Program measures value of care provided by participating Medicare hospitals while creating financial incentives for quality improvement and fostering increased transparency. Limited information is available comparing hospital performance across healthcare business models. Study Design 2015 hospital Value-Based Purchasing Program results were used to examine hospital performance by business model. General linear modeling assessed differences in mean total performance score, hospital case mix index, and differences after adjustment for differences in hospital case mix index. Results Of 3089 hospitals with Total Performance Scores (TPS), categories of representative healthcare business models included 104 Physician-owned Surgical Hospitals (POSH), 111 University HealthSystem Consortium (UHC), 14 US News & World Report Honor Roll (USNWR) Hospitals, 33 Kaiser Permanente, and 124 Pioneer Accountable Care Organization affiliated hospitals. Estimated mean TPS for POSH (64.4, 95% CI 61.83, 66.38) and Kaiser (60.79, 95% CI 56.56, 65.03) were significantly higher compared to all remaining hospitals while UHC members (36.8, 95% CI 34.51, 39.17) performed below the mean (p UHC members (mean =1.99, p<0.0001) while Kaiser Permanente hospitals had lower case mix value (mean =1.54, p<0.0001). Re-estimation of TPS did not change the original results after adjustment for differences in hospital case mix index.

    Graduating military preliminary interns are often required to fill flight surgeon billets. General surgery preliminary interns get experience evaluating surgical and trauma patients, but receive very little training in primary care and flight medicine. At a joint military and civilian training program, we developed a supplemental curriculum to help transition our interns into flight medicine. From 2013 to 2016, we developed a lecture series focused on aerospace medicine, primary care, and specialty topics including dermatology, ophthalmology, orthopedics, pediatrics, psychiatry, and women's health. During the 2016 iteration attended by 10 interns, pre- and post-participation 10-item Likert scale surveys were administered. Questions focused on perceived preparedness for primary care role and overall enthusiasm for flight medicine. Open-ended surveys from 2013 to 2016 were also used to gauge the effect of the curriculum. The composite number of agreement responses (indicating increased comfort with presented material) increased 63% after course completion. Disagreement responses and neutral responses decreased 78% and 30%, respectively. Open-ended surveys from 14 participants showed an overall positive impression of the curriculum with all indicating it aided their transition to flight medicine. Survey responses indicate an overall perceived benefit from participation in the curriculum with more confidence in primary care topics and improved transition to a flight medicine tour. This model for supplemental aerospace medicine and primary care didactics should be integrated into any residency program responsible for training military preliminary interns who may serve as flight surgeons.

    Langenfeld, Sean J; Vargo, Daniel J; Schenarts, Paul J

    Unprofessional behavior is common among surgical residents and faculty surgeons on Facebook. Usage of social media outlets such as Facebook and Twitter is growing at exponential rates, so it is imperative that surgery program directors (PDs) focus on professionalism within social media, and develop guidelines for their trainees and surgical colleagues. Our study focuses on the surgery PDs current approach to online professionalism within surgical education. An online survey of general surgery PDs was conducted in October 2015 through the Association for Program Directors in Surgery listserv. Baseline PD demographics, usage and approach to popular social media outlets, existing institutional policies, and formal curricula were assessed. A total of 110 PDs responded to the survey (110/259, 42.5% response rate). Social media usage was high among PDs (Facebook 68% and Twitter 40%). PDs frequently viewed the social media profiles of students, residents, and faculty. Overall, 11% of PDs reported lowering the rank or completely removing a residency applicant from the rank order list because of online behavior, and 10% reported formal disciplinary action against a surgical resident because of online behavior. Overall, 68% of respondents agreed that online professionalism is important, and that residents should receive instruction on the safe use of social media. However, most programs did not have formal didactics or known institutional policies in place. Use of social media is high among PDs, and they often view the online behavior of residency applicants, surgical residents, and faculty surgeons. Within surgical education, there needs to be an increased focus on institutional policies and standardized curricula to help educate physicians on social media and online professionalism.

    A large national surgical registry was used to establish national benchmarks and associated predictors of major neurologic complications (i.e., coma and stroke) after surgical clipping of unruptured intracranial aneurysms. The American College of Surgeons National Surgical Quality Improvement Program data set between 2007 and 2013 was used for this retrospective cohort analysis. Demographic, comorbidity, and operative characteristics associated with the development of a major neurologic complication (i.e., coma or stroke) were elucidated using a backward selection stepwise logistic regression analysis. This model was subsequently used to fit a predictive score for major neurologic complications. Inclusion criteria were met by 662 patients. Of these patients, 57 (8.61%) developed a major neurologic complication (i.e., coma or stroke) within the 30-day postoperative period. On multivariable analysis, operative time (log odds 0.004 per minute; 95% confidence interval [CI], 0.002-0.007), age (log odds 0.05 per year; 95% CI, 0.02-0.08), history of chronic obstructive pulmonary disease (log odds 1.26; 95% CI, 0.43-2.08), and diabetes (log odds 1.15; 95% CI, 0.38-1.91) were associated with an increased odds of major neurologic complications. When patients were categorized according to quartile of a predictive score generated from the multivariable analysis, rates of major neurologic complications were 1.8%, 4.3%, 6.7%, and 21.2%. Using a large, national multi-institutional cohort, this study established representative national benchmarks and a predictive scoring system for major neurologic complications following operative management of unruptured intracranial aneurysms. The model may assist with risk stratification and tailoring of decision making in surgical candidates. Copyright © 2016 Elsevier Inc. All rights reserved.

    The primary goal of a residency program is to prepare trainees for unsupervised care. Duty hour restrictions imposed throughout the prior decade require that residents work significantly fewer hours. Moreover, various stakeholders (e.g. the hospital, mentors, other residents, educators, and patients) require them to prioritize very different activities, often conflicting with their learning goals. Surgical residents' learning goals include providing continuity throughout a patient's pre-, peri-, and post-operative care as well as achieving sufficient surgical experience levels in various procedure types and participating in various formal educational activities, among other things. To complicate matters, senior residents often compete with other residents for surgical experience. This paper features experiments using an optimization model and a real dataset. The experiments test the viability of achieving the above goals at a major academic center using existing models of delivering medical education and training to surgical residents. It develops a detailed multi-objective, two-stage stochastic optimization model with anticipatory capabilities solved over a rolling time horizon. A novel feature of the models is the incorporation of learning curve theory in the objection function. Using a deterministic version of the model, we identify bounds on the achievement of learning goals under existing training paradigms. The computational results highlight the structural problems in the current surgical resident educational system. These results further corroborate earlier findings and suggest an educational system redesign is necessary for surgical medical residents.

    OBJECTIVE Existing studies have shown a high overall rate of adverse events (AEs) following pediatric neurosurgical procedures. However, little is known regarding the morbidity of specific procedures or the association with risk factors to help guide quality improvement (QI) initiatives. The goal of this study was to describe the 30-day mortality and AE rates for pediatric neurosurgical procedures by using the American College of Surgeons (ACS) National Surgical Quality Improvement Program-Pediatrics (NSQIP-Peds) database platform. METHODS Data on 9996 pediatric neurosurgical patients were acquired from the 2012-2014 NSQIP-Peds participant user file. Neurosurgical cases were analyzed by the NSQIP-Peds targeted procedure categories, including craniotomy/craniectomy, defect repair, laminectomy, shunts, and implants. The primary outcome measure was 30-day mortality, with secondary outcomes including individual AEs, composite morbidity (all AEs excluding mortality and unplanned reoperation), surgical-site infection, and unplanned reoperation. Univariate analysis was performed between individual AEs and patient characteristics using Fischer's exact test. Associations between individual AEs and continuous variables (duration from admission to operation, work relative value unit, and operation time) were examined using the Student t-test. Patient characteristics and continuous variables associated with any AE by univariate analysis were used to develop category-specific multivariable models through backward stepwise logistic regression. RESULTS The authors analyzed 3383 craniotomy/craniectomy, 242 defect repair, 1811 laminectomy, and 4560 shunt and implant cases and found a composite overall morbidity of 30.2%, 38.8%, 10.2%, and 10.7%, respectively. Unplanned reoperation rates were highest for defect repair (29.8%). The mortality rate ranged from 0.1% to 1.2%. Preoperative ventilator dependence was a significant predictor of any AE for all procedure groups, whereas

    The objective of this study was to identify risk factors for free flap failure among various anatomically based free flap subgroups. The 2005 to 2012 American College of Surgeons National Surgical Quality Improvement Program database was queried for patients undergoing microvascular free tissue transfer based on current procedural terminology codes. Univariate analysis was performed to identify any association between flap failure and the following factors: age, gender, race, body mass index (BMI), diabetes, smoking, alcohol use, hypertension, intraoperative transfusion, functional health status, American Society of Anesthesiologists class, operative time, and flap location. Factors yielding a significance of P free flap reconstruction met inclusion criteria. Multivariate logistic regression identified BMI (adjusted odds ratio [AOR] = 1.07, P = 0.004) and male gender (AOR = 2.16, P = 0.033) as independent risk factors for flap failure. Among the "breast flaps" subgroup, BMI (AOR = 1.075, P = 0.012) and smoking (AOR = 3.35, P = 0.02) were independent variables associated with flap failure. In "head and neck flaps," operative time (AOR = 1.003, P = 0.018) was an independent risk factor for flap failure. No independent risk factors were identified for the "extremity flaps" or "trunk flaps" subtypes. BMI, smoking, and operative time were identified as independent risk factors for free flap failure among all flaps or within flap subsets.

    To determine whether concurrently performed operations are associated with an increased risk for adverse events. Concurrent operations occur when a surgeon is simultaneously responsible for critical portions of 2 or more operations. How this practice affects patient outcomes is unknown. Using American College of Surgeons' National Surgical Quality Improvement Program data from 2014 to 2015, operations were considered concurrent if they overlapped by ≥60 minutes or in their entirety. Propensity-score-matched cohorts were constructed to compare death or serious morbidity (DSM), unplanned reoperation, and unplanned readmission in concurrent versus non-concurrent operations. Multilevel hierarchical regression was used to account for the clustered nature of the data while controlling for procedure and case mix. There were 1430 (32.3%) surgeons from 390 (77.7%) hospitals who performed 12,010 (2.3%) concurrent operations. Plastic surgery (n = 393 [13.7%]), otolaryngology (n = 470 [11.2%]), and neurosurgery (n = 2067 [8.4%]) were specialties with the highest proportion of concurrent operations. Spine procedures were the most frequent concurrent procedures overall (n = 2059/12,010 [17.1%]). Unadjusted rates of DSM (9.0% vs 7.1%; P continuous self-regulation and proactive disclosure to patients.

    Full Text Available Abstract Background Limited resources, whether public or private, demand prioritisation among competing needs to maximise productivity. With a substantial increase in the number of reported HIV cases, little work has been done to understand how resources have been distributed and what factors may have influenced allocation within the newly introduced Enhanced National AIDS Control Program of Pakistan. The objective of this study was to identify perceptions of decision makers about the process of resource allocation within Pakistan's Enhanced National AIDS Control Program. Methods A qualitative study was undertaken and in-depth interviews of decision makers at provincial and federal levels responsible to allocate resources within the program were conducted. Results HIV was not considered a priority issue by all study participants and external funding for the program was thought to have been accepted because of poor foreign currency reserves and donor agency influence rather than local need. Political influences from the federal government and donor agencies were thought to manipulate distribution of funds within the program. These influences were thought to occur despite the existence of a well-laid out procedure to determine allocation of public resources. Lack of collaboration among departments involved in decision making, a pervasive lack of technical expertise, paucity of information and an atmosphere of ad hoc decision making were thought to reduce resistance to external pressures. Conclusion Development of a unified program vision through a consultative process and advocacy is necessary to understand goals to be achieved, to enhance program ownership and develop consensus about how money and effort should be directed. Enhancing public sector expertise in planning and budgeting is essential not just for the program, but also to reduce reliance on external agencies for technical support.

    We aimed to develop an effective system for surgical site infection (SSI) surveillance and examine the current domestic state of SSIs for common abdominal surgeries in Korea. The Korean Surgical Site Infection Surveillance (KOSSIS) program was developed as an SSI surveillance system. A prospective multicenter study in nine university-affiliated or general hospitals was conducted for patients who underwent gastrectomy, cholecystectomy, appendectomy, colectomy, or proctectomy between August 16 and September 30 in 2012. Patients were monitored for up to 30 days by combining direct observation and a postdischarge surgeon survey. Data on SSIs were prospectively collected with KOSSIS secretarial support according to a common protocol. Operation-specific SSI rates were stratified according to risk factors and compared with data from the Korean Nosocomial Infections Surveillance System (KONIS) and National Healthcare Safety Network. A focus group interview was conducted with participating hospitals for feedback. A total of 1,088 operations were monitored: 207 gastrectomies, 318 cholecystectomies, 270 appendectomies, 197 colectomies, and 96 proctectomies. Operation-specific SSI rates determined by the KOSSIS program were substantially higher than those found in KONIS (7.73% [95% confidence interval, 4.5%-12.3%] vs. 3.4% for gastrectomies, 10.15% [95% confidence interval, 6.1%-15.2%] vs. 4.0% for colectomy, and 13.5% [95% confidence interval, 7.4%-22.0%] vs. 4.2% for proctectomy). Despite a short surveillance period and heterogenous group of hospitals, our results suggest that KOSSIS could be a useful program to enhance SSI surveillance in Korea.

    2015-06-01

    Innovation in surgical techniques, technology, and care processes are essential for improving the care and outcomes of surgical patients, including children. The time and cost associated with surgical innovation can be significant, and unless it leads to improvements in outcome at equivalent or lower costs, it adds little or no value from the perspective of the patients, and decreases the overall resources available to our already financially constrained healthcare system. The emergence of a safety and quality mandate in surgery, and the development of the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) allow needs-based surgical care innovation which leads to value-based improvement in care. In addition to general and procedure-specific clinical outcomes, surgeons should consider the measurement of quality from the patients' perspective. To this end, the integration of validated Patient Reported Outcome Measures (PROMs) into actionable, benchmarked institutional outcomes reporting has the potential to facilitate quality improvement in process, treatment and technology that optimizes value for our patients and health system.

    Surgical competency requires sound clinical judgment, a systematic diagnostic approach, and integration of a wide variety of nontechnical skills. This more complex aspect of clinician development has traditionally been difficult to measure through standard assessment methods. This study was conducted to use the Clinical Practice Instrument (CPI) to measure nontechnical diagnostic and management skills during otolaryngology residency training; to determine whether there is demonstrable change in these skills between residents who are in postgraduate years (PGYs) 2, 4, and 5; and to evaluate whether results vary according to subspecialty topic or method of administration. Prospective study using the CPI, an instrument with previously established internal consistency, reproducibility, interrater reliability, discriminant validity, and responsiveness to change, in an otolaryngology residency training program. The CPI was used to evaluate progression in residents' ability to evaluate, diagnose, and manage case-based clinical scenarios. A total of 248 evaluations were performed in 45 otolaryngology resident trainees at regular intervals. Analysis of variance with nesting and postestimation pairwise comparisons were used to evaluate total and domain scores according to training level, subspecialty topic, and method of administration. Longitudinal residency educational initiative. Assessment with the CPI during PGYs 2, 4, and 5 of residency. Among the 45 otolaryngology residents (248 CPI administrations), there were a mean (SD) of 5 (3) administrations (range, 1-4) during their training. Total scores were significantly different among PGY levels of training, with lower scores seen in the PGY-2 level (44 [16]) compared with the PGY-4 (64 [13]) or PGY-5 level (69 [13]) (P otolaryngology (mean [SD], 72 [14]) than in subspecialties (range, 55 [12], P = .003, to 56 [19], P < .001).

    Mammogram screening is the most effective method for the early detection of breast cancer. The objective of this study is to evaluate the degree of knowledge, the opinion and the participation in the early breast cancer detection program on the part of the family physicians of the Autonomous Community of Madrid. The population studied was comprised of family physicians from Madrid Health District Seven. An anonymous, self-administered questionnaire comprised of 30 questions grouped into physicians characteristics and opinion concerning the early breast cancer detection programs. A total of 46% of the physicians replied. A total of 94% of the physicians believed that it is their duty to inform their patients concerning preventive activities, including breast cancer screening, and 95% believed their advice to be useful for convincing women to have a mammogram. A total of 72% believed information to be lacking on this program. During the time when mammograms are being taken at their centres, 24% of the physicians surveyed always or almost always ask the women if they have any doubts or would like further information, 43% having set up appointments for them and 95% advising them to have a mammogram taken. The family physicians have a good opinion of the early breast cancer detection program and feel their advice to be effective for improving the participation in the program. They report lack of information and inform women about the program to only a small degree.

    Full Text Available The American College of Surgeons' National Surgical Quality Improvement Program (NSQIP is the first nationally validated, risk-adjusted, outcomes-based program to measure and compare the quality of surgical care across North America. Participation in this program may provide an opportunity to reduce the incidence of adverse events related to surgery.A systematic review of the literature was performed. MedLine, EMBASE and PubMed were searched for studies relevant to NSQIP. Patient characteristics, intervention, and primary outcome measures were abstracted. The intervention was participation in NSQIP and monitoring of Individual Site Summary Reports with or without implementation of a quality improvement program. The outcomes of interest were change in peri-operative adverse events and mortality represented by pooled risk ratios (pRR and 95% confidence intervals (CI.Eleven articles reporting on 35 health care institutions were included. Nine (82% of the eleven studies implemented a quality improvement program. Minimal improvements in superficial (pRR 0.81; 95% CI 0.72-0.91, deep (pRR 0.82; 95% CI0.64-1.05 and organ space (pRR 1.15; 95% CI 0.96-1.37 infections were observed at centers that did not institute a quality improvement program. However, centers that reported formal interventions for the prevention and treatment of infections observed substantial improvements (superficial pRR 0.55, 95% CI 0.39-0.77; deep pRR 0.61, 95% CI 0.50-0.75, and organ space pRR 0.60, 95% CI 0.50-0.71. Studies evaluating other adverse events noted decreased incidence following NSQIP participation and implementation of a formal quality improvement program.These data suggest that NSQIP is effective in reducing surgical morbidity. Improvement in surgical quality appears to be more marked at centers that implemented a formal quality improvement program directed at the reduction of specific morbidities.

    Umbilical hernias present commonly during pregnancy secondary to increased intra-abdominal pressure. As a result, umbilical hernia incarceration or strangulation may affect pregnant females. The purpose of this study is to detail the operative management and 30-day outcomes of umbilical hernias in pregnant patients using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP). All female patients undergoing umbilical hernia repair during pregnancy were identified within the ACS-NSQIP. Preoperative patient variables, intraoperative variables, and 30-day patient morbidity and mortality outcomes were investigated using a variety of statistical tests. A total of 126 pregnant patients underwent umbilical hernia repair from 2005 to 2014; 73 (58%) had incarceration or strangulation at the time of surgical intervention. The majority of patients (95%) underwent open umbilical hernia repair. Superficial surgical site infection was the most common morbidity in patients undergoing open umbilical hernia repair. Based on review of the ACS-NSQIP database, the incidence of umbilical hernia repair during pregnancy is very low; however, the majority of patients required repair for incarceration of strangulation. When symptoms develop, these hernias can be repaired with minimal 30-day morbidity to the mother. Additional studies are needed to determine the long-term recurrence rate of umbilical hernia repairs performed in pregnant patients and the effects of surgical intervention and approach on the fetus.

Retrospective cohort study (Canadian Task Force classification II-2). National Surgical Quality Improvement Program data. Women who underwent abdominal or laparoscopic hysterectomy performed for benign indications from 2005 to 2011. Univariable and multivariable logistic regression analyses were used to identify predictors of SSI and its association with other postoperative complications. Odds ratios were adjusted for patient demographic data, comorbidities, preoperative laboratory values, and operative factors. Of 28 366 patients, 758 (3%) were diagnosed with SSI. SSI occurred more often after abdominal than laparoscopic hysterectomy (4% vs 2%; p hysterectomy, predictors of SSI included diabetes, smoking, respiratory comorbidities, overweight or obesity, American Society of Anesthesiologists class ≥ 3, perioperative blood transfusion, and operative time >180 minutes. Among those who underwent laparoscopic hysterectomy, predictors of SSI included perioperative blood transfusion, operative time >180 minutes, serum creatinine concentration ≥ 2 mg/dL, and platelet count ≥ 350 000 cells/mL(3). For patients with deep or organ/space SSI, significant predictors included perioperative blood transfusion and American Society of Anesthesiologists class ≥ 3 for abdominal hysterectomy, and non-white race, renal comorbidities, preoperative or perioperative blood transfusion, and operative time >180 minutes for laparoscopic hysterectomy. SSI was associated with longer hospital stay and higher rates of repeat operation, sepsis, renal failure, and wound dehiscence. SSI was not associated with increased 30-day mortality. SSI occurred more often after abdominal hysterectomy than laparoscopic hysterectomy performed to treat benign gynecologic disease. SSI was associated with

This study determined a single institution's 30-day SSI rate and benchmarked it against that among national institutions participating in the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP.MethodsWomen who underwent ITEBR with/without acellular dermal matrix (ADM were identified using the ACS-NSQIP database between 2005 and 2011. Patient characteristics associated with the 30-day SSI rate were determined, and differences in rates between our institution and the national database were assessed.Results12,163 patients underwent ITEBR, including 263 at our institution. SSIs occurred in 416 (3.4% patients nationwide excluding our institution, with lower rates observed at our institution (1.9%. Nationwide, SSIs were significantly more common in ITEBR patients with ADM (4.5% compared to non-ADM patients (3.2%, P=0.005, and this trend was observed at our institution (2.1% vs. 1.6%, P=1.00.

    With the increasing acuity levels of hospitalized patients, faculty members struggle with accessing clinical sites for undergraduate students. Teaching students how to interact with patients and their families can often take second place to attending to the many needs and safety issues in caring for acutely ill individuals, particularly in medical-surgical settings. Over the past several years, the psychiatric and medical-surgical faculty members in the nursing department of a college in Boston have struggled with how best to prepare students for both the physical and psychosocial aspects of care. In this article, the evolution of our psychiatric consultation-liaison model is discussed.

    The U.S. Department of Energy (DOE) Fuel Cell Technologies Program (FCT) conducts comprehensive efforts to enable the widespread commercialization of fuel cells in diverse sectors of the economy - with emphasis on applications that will most effectively strengthen our nation's energy security and improve our stewardship of the environment. Expanding the use of fuel cells requires a sustained education effort to lay the foundation for future commercial market introduction. The FCT education subprogram seeks to facilitate fuel cell demonstrations and support future commercialization by providing technically accurate and objective information to key target audiences both directly and indirectly involved in the use of fuel cells today. These key target audiences include a public that is familiar and comfortable with using a new fuel, state and local government officials who understand the near-term realities and long-term potential of the technology, an educated business and industry component, and trained safety and codes officials. With this in mind, the DOE FCT program established an education key activity to address the training and informational needs of target audiences that have a role in the near-term transition and the long-term development of a hydrogen economy. Whether or not changes can be attributed to the program, designing and maintaining an effective education program entails measuring baseline awareness and periodically measuring what has been learned. The purpose of this report is to document the data and results of statistical surveys undertaken in 2008 and 2009 to measure and establish changes in understanding and awareness about hydrogen and fuel cell technologies since a baseline survey was conducted in 2004. This report is essentially a data book, a digest of the survey data and an exposition of changes in knowledge of and opinions about hydrogen and fuel cell technology since 2004. Many conclusions can be made from the survey data. However

    Full Text Available Background: Because of ethical and medico-legal aspects involved in the training of cutaneous surgical skills on living patients, human cadavers and living animals, it is necessary the search for alternative and effective forms of training simulation. Aims: To propose and describe an alternative methodology for teaching and learning the principles of cutaneous surgery in a medical undergraduate program by using a chicken-skin bench model. Materials and Methods: One instructor for every four students, teaching materials on cutaneous surgical skills, chicken trunks, wings, or thighs, a rigid platform support, needled threads, needle holders, surgical blades with scalpel handles, rat-tooth tweezers, scissors, and marking pens were necessary for training simulation. Results: A proposal for simulation-based training on incision, suture, biopsy, and on reconstruction techniques using a chicken-skin bench model distributed in several sessions and with increasing levels of difficultywas structured. Both feedback and objective evaluations always directed to individual students were also outlined. Conclusion: The teaching of a methodology for the principles of cutaneous surgery using a chicken-skin bench model versatile, portable, easy to assemble, and inexpensive is an alternative and complementary option to the armamentarium of methods based on other bench models described.

  9. Is Teaching Simple Surgical Skills Using an Operant Learning Program More Effective Than Teaching by Demonstration?

    2016-04-01

    A surgical procedure is a complex behavior that can be constructed from foundation or component behaviors. Both the component and the composite behaviors built from them are much more likely to recur if it they are reinforced (operant learning). Behaviors in humans have been successfully reinforced using the acoustic stimulus from a mechanical clicker, where the clicker serves as a conditioned reinforcer that communicates in a way that is language- and judgment-free; however, to our knowledge, the use of operant-learning principles has not been formally evaluated for acquisition of surgical skills. Two surgical tasks were taught and compared using two teaching strategies: (1) an operant learning methodology using a conditioned, acoustic reinforcer (a clicker) for positive reinforcement; and (2) a more classical approach using demonstration alone. Our goal was to determine whether a group that is taught a surgical skill using an operant learning procedure would more precisely perform that skill than a group that is taught by demonstration alone. Two specific behaviors, "tying the locking, sliding knot" and "making a low-angle drill hole," were taught to the 2014 Postgraduate Year (PGY)-1 class and first- and second-year medical students, using an operant learning procedure incorporating precise scripts along with acoustic feedback. The control groups, composed of PGY-1 and -2 nonorthopaedic surgical residents and first- and second-year medical students, were taught using demonstration alone. The precision and speed of each behavior was recorded for each individual by a single experienced surgeon, skilled in operant learning. The groups were then compared. The operant learning group achieved better precision tying the locking, sliding knot than did the control group. Twelve of the 12 test group learners tied the knot and precisely performed all six component steps, whereas only four of the 12 control group learners tied the knot and correctly performed all six

    OBJECTIVE The goal of this study was to use a large national registry to evaluate the 30-day cumulative incidence and predictors of adverse events, readmissions, and reoperations after surgery for primary and secondary spinal tumors. METHODS Data from adult patients who underwent surgery for spinal tumors (2011-2014) were extracted from the prospective National Surgical Quality Improvement Program (NSQIP) registry. Multivariable logistic regression was used to evaluate predictors of reoperation, readmission, and major complications (death, neurological, cardiopulmonary, venous thromboembolism [VTE], surgical site infection [SSI], and sepsis). Variables screened included patient age, sex, tumor location, American Society of Anesthesiologists (ASA) physical classification, preoperative functional status, comorbidities, preoperative laboratory values, case urgency, and operative time. Additional variables that were evaluated when analyzing readmission included complications during the surgical hospitalization, hospital length of stay (LOS), and discharge disposition. RESULTS Among the 2207 patients evaluated, 51.4% had extradural tumors, 36.4% had intradural extramedullary tumors, and 12.3% had intramedullary tumors. By spinal level, 20.7% were cervical lesions, 47.4% were thoracic lesions, 29.1% were lumbar lesions, and 2.8% were sacral lesions. Readmission occurred in 10.2% of patients at a median of 18 days (interquartile range [IQR] 12-23 days); the most common reasons for readmission were SSIs (23.7%), systemic infections (17.8%), VTE (12.7%), and CNS complications (11.9%). Predictors of readmission were comorbidities (dyspnea, hypertension, and anemia), disseminated cancer, preoperative steroid use, and an extended hospitalization. Reoperation occurred in 5.3% of patients at a median of 13 days (IQR 8-20 days) postoperatively and was associated with preoperative steroid use and ASA Class 4-5 designation. Major complications occurred in 14.4% of patients: the

    An increasing number of patients with congenital heart disease survive to adulthood. Expert opinion suggests that noncardiac surgery is a high-risk event, but few data describe perioperative outcomes in this population. Using the National Surgical Quality Improvement Program database, we identified a cohort of patients aged 18 to 39 years with prior heart surgery who underwent noncardiac surgery between 2005 and 2010. A comparison cohort with no prior cardiovascular surgery was matched on age, sex, race/ethnicity, operation year, American Society of Anesthesiologists physical status, and Current Procedural Terminology code. A study cohort consisting of 1191 patients was compared with a cohort of 5127 patients. Baseline dyspnea, inpatient status at the time of surgery, and a prior operation within 30 days were more common in the study cohort. Postoperative outcomes were less favorable in the study cohort. Observed rates of death, perioperative cardiac arrest, myocardial infarction, stroke, respiratory complications, renal failure, sepsis, venous thromboembolism, perioperative transfusion, and reoperation were significantly higher in the study cohort (P heart disease are at risk for adverse outcomes and support the need for further registry-based investigations.

    Objective In a single-center cohort of surgical patients we assessed the association between postoperative change in serum creatinine (sCr) and adverse outcomes and compared the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP)’s definition for acute kidney injury (NSQIP-AKI) with consensus RIFLE (Risk, Injury, Failure, Loss, and End-stage Kidney) and KDIGO (Kidney Disease: Improving Global Outcomes) definitions. Design Retrospective single center cohort. Setting Academic tertiary medical center. Patients 27,841 adult patients with no previous history of chronic kidney disease undergoing major surgery. Intervention RIFLE defines AKI as change in sCr greater than or equal to 50% while KDIGO uses 0.3 mg/dl change from the reference sCr. Since NSQIP defines AKI as sCr change > 2mg/dl, it may underestimate the risk associated with less severe AKI. Measurements The optimal discrimination limits (ODL) for both percent and absolute sCr changes were calculated by maximizing sensitivity and specificity along the receiver operating characteristic (ROC) curves for postoperative complications and mortality. Main Results Although prevalence of RIFLE-AKI was 37%, only 7% of RIFLE-AKI patients would be diagnosed with AKI using the NSQIP definition. In multivariable logistic models patients with RIFLE or KDIGO-AKI had a 10 times higher odds of dying compared to patients without AKI. The ODLs for change in sCr associated with adverse postoperative outcomes were as low as 0.2 mg/dl while the NSQIP discrimination limit of 2.0 mg/dl had low sensitivity (0.05 – 0.28). Conclusion Current ACS NSQIP definition underestimates the risk associated with mild and moderate AKI otherwise captured by the consensus RIFLE and KDIGO criteria. PMID:23928835

  17. A Consensual Linear Opinion Pool

    CERN Document Server

    Carvalho, Arthur

    2012-01-01

    We propose a pooling method to aggregate expert opinions. Intuitively, it works as if the experts were continuously updating their opinions in order to accommodate the expertise of others. Each updated opinion takes the form of a linear opinion pool, where the weight that an expert assigns to a peer's opinion is inversely related to the distance between their opinions. In other words, experts are assumed to prefer opinions that are close to their own opinions. We prove that such an updating process leads to consensus, i.e., the experts all converge towards the same opinion. Further, we show that if experts are rewarded using the quadratic scoring rule, then the above mentioned assumption follows naturally. We empirically demonstrate the efficacy of our method using real-world data.

    2016-07-01

    We consider the process of opinion formation in a society of interacting agents, where there is a set B of socially accepted rules. In this scenario, we observed that agents, represented by simple feed-forward, adaptive neural networks, may have a conservative attitude (mostly in agreement with B ) or liberal attitude (mostly in agreement with neighboring agents) depending on how much their opinions are influenced by their peers. The topology of the network representing the interaction of the society's members is determined by a graph, where the agents' properties are defined over the vertexes and the interagent interactions are defined over the bonds. The adaptability of the agents allows us to model the formation of opinions as an online learning process, where agents learn continuously as new information becomes available to the whole society (online learning). Through the application of statistical mechanics techniques we deduced a set of differential equations describing the dynamics of the system. We observed that by slowly varying the average peer influence in such a way that the agents attitude changes from conservative to liberal and back, the average social opinion develops a hysteresis cycle. Such hysteretic behavior disappears when the variance of the social influence distribution is large enough. In all the cases studied, the change from conservative to liberal behavior is characterized by the emergence of conservative clusters, i.e., a closed knitted set of society members that follow a leader who agrees with the social status quo when the rule B is challenged.

    Single-suture craniosynostosis (SSC) is a common craniofacial condition with potential neurocognitive sequelae. To quantify any long-term functional academic and behavioural difficulties of children with SSC as indicated by the need for individualized education programs (IEPs), despite having undergone surgical treatment. Records of all school-age patients from 1992 to 2011 who underwent operative intervention for SSC were identified. Fifty-nine patients' guardians were contacted by telephone to provide informed consent for completion of a mailed standardized questionnaire querying demographic information as well as information regarding the patient's health, family and educational history; specifically whether the patient had ever been provided educational support as delineated in an IEP. The primary outcome measure was the history of the patient being assigned educational support as delineated in an IEP. Thirty-seven consenting guardians completed and returned the standardized questionnaire (response rate 62.7%). Twenty-one patients were male and 16 were female, with an age range of five to 14 years (mean age 10.2 years). Eleven (29.7%) patients had a previous history of or currently were receiving educational support delineated in an IEP. A higher proportion of school-age patients with a history of SSC (status postsurgical intervention) in the present study received educational support delineated in an IEP than the proportion of IEPs in the general student population of the United States (11.3%).

    Determining predictors of surgical site infection (SSI) in a large cohort is important for the design of accurate SSI surveillance programs. We hypothesized that additional organ resection and pelvic exenterative procedures are associated independently with a higher risk of SSI. Patients in the American College of Surgeons National Surgical Quality Improvement Program® (ACS NSQIP®; American College of Surgeons, Chicago, IL) database (2005-2012) were identified (n=112,282). Surgical site infection (superficial or deep SSI) at 30 d was the primary outcome. Using primary and secondary CPT® codes (American Medical Association, Chicago, IL) pelvic exenteration was defined and additional organ resection was defined as: bladder resection/repair, hysterectomy, partial vaginectomy, additional segmental colectomy, small bowel, gastric, or diaphragm resection. Univariable analysis of patient and procedure factors identified significant (p40 (OR: 2.51), pulmonary comorbidities (OR: 1.22), smoking (OR: 1.24), bowel obstruction (OR: 1.40), wound classification 3 or 4 (OR: 1.18), and abdominoperineal resection (OR: 1.58). Laparoscopic or laparoscopically assisted procedures offered a protective effect against incision infection (OR: 0.55). Additional organ resection (OR: 1.08) was also associated independently with SSI, but the magnitude of the effect was decreased after accounting for operative duration. In the analysis that excludes operative duration, pelvic exenteration is associated with SSI (OR: 1.38), but incorporating operative duration into the model results in this variable becoming non-significant. In addition to other factors, obesity, surgery for bowel obstruction, abdominoperineal resection, and additional organ resection are independently associated with a higher risk of SSI. Surgical site infection risk in pelvic exenteration and multiple organ resection cases appears to be mediated by prolonged operative duration. In these established high-risk sub-groups of

    This paper studies the evolution of the distribution of opinions in a population of individuals in which there exist two distinct subgroups of highly-committed, well-connected opinion leaders endowed with a strong convincing power. Each individual, located at a vertex of a directed graph, is characterized by her name, the list of people she is interacting with, her level of awareness, and her opinion. Various temporal evolutions according to different local rules are compared in order to find under which conditions the formation of strongly polarized subgroups, each adopting the opinion of one of the two groups of opinion leaders, is favored.

    Obesity has increased dramatically in the American population during the past 2 decades. Approximately 35% of adults are obese. Although obesity represents a major health issue, the association between obesity and operative outcomes has been a subject of controversy. We queried the National Surgical Quality Improvement Program (NSQIP) database to determine whether an increased body mass index (BMI) affects the outcomes of pulmonary resection for lung cancer. We identified 6,567 patients with a diagnosis of lung cancer who underwent pulmonary resection from 2005 to 2012 in the NSQIP database. We stratified this population into 6 BMI groups according to the World Health Organization classification. The primary outcome measured was 30-day mortality; secondary outcomes included length of stay (LOS), operative time, and NSQIP-measured postoperative complications. We performed both unadjusted analysis and adjusted multivariable analysis, controlling for statistically significant variables. Adjusted multivariable logistic regression showed no increase in 30-day mortality, overall morbidity, and serious morbidity among obese patients. Adjusted Poisson regression revealed greater operative times for both obese and underweight patients compared with normal weight patients. Overall, obese patients were younger and had a greater percentage of preoperative comorbidities, including diabetes, hypertension, dyspnea, renal disease, and history of previous cardiac surgery. The prevalence of active smokers was greater among patients with low and normal BMI. Underweight patients had a greater risk-adjusted LOS relative to normal weight patients, whereas overweight and mildly obese patients had lesser risk-adjusted LOS. The results of our analysis suggest that obesity does not confer greater mortality and morbidity after lung resection. Copyright © 2015 Elsevier Inc. All rights reserved.

    The use and usefulness of Advance Directives has led to a lot of controversy about their validity and effectiveness. Those areas are unexplored in our country from the perspective of representatives. To determine the opinion of the representatives appointed in a registered Statement of Advance Directives (SAD) on the use of this document. Telephone survey of representatives of 146 already dead people and who, since February 2012, had registered a SAD document. More the two-thirds (98) of respondents recalled that the SAD was consulted, with 86 (58.9%) saying that their opinion as representative was consulted, and 120 (82.1%) believe that the patient's will was respected. Of those interviewed, 102 (69.9%) believe that patients who had previously planned their care using a SAD had a good death, with 33 (22.4%) saying it could have been better, and 10 (6.9%) believe they suffered greatly. The SAD were mostly respected and consulted, and possibly this is related to the fact that most of the representatives declare that the death of those they represented was perceived as comfortable. It would be desirable to conduct further studies addressed at health personnel in order to know their perceptions regarding the use of Advance Directives in the process of dying.

  17. Expert opinion vs. empirical evidence

    Herman, Rod A; Raybould, Alan

    2014-01-01

    Expert opinion is often sought by government regulatory agencies when there is insufficient empirical evidence to judge the safety implications of a course of action. However, it can be reckless to continue following expert opinion when a preponderance of evidence is amassed that conflicts with this opinion. Factual evidence should always trump opinion in prioritizing the information that is used to guide regulatory policy. Evidence-based medicine has seen a dramatic upturn in recent years spurred by examples where evidence indicated that certain treatments recommended by expert opinions increased death rates. We suggest that scientific evidence should also take priority over expert opinion in the regulation of genetically modified crops (GM). Examples of regulatory data requirements that are not justified based on the mass of evidence are described, and it is suggested that expertise in risk assessment should guide evidence-based regulation of GM crops.

  18. Arms and alliance in Japanese public opinion

    Energy Technology Data Exchange (ETDEWEB)

    Umemoto, T.

    1985-01-01

    This thesis analyzes the transformation of Japanese public opinion concerning the nation's security posture during the past decade. Until the early 1970s, the peculiar strength of a neutralist-pacifist outlook among the Japanese people, which arose in large part from the absence of a serious external threat severely encumbered Tokyo's defense efforts in the context of the alliance with the United States. In particular, such state of domestic opinion gave rise to what the author has elected to call the institutionalized constraints - limitations deriving from constitutional interpretation, the Three Non-Nuclear Principles, and the Three Principles on Weapons Exports - on the scope of such endeavors. It moreover prepared the condition for the Government's adoption of restrictive military buildup policies in the National Defense Program Outline. Over the past decade, however, as Japan's security environment has deteriorated with the growth of the putative Soviet threat, and as the United States and China have come to expect greater Japanese defense efforts, the climate of opinion within Japan has gradually shifted in favor of a security posture based on the Mutual Security Treaty (MST) and the Self-Defense Forces (SDFs). Opinion polls have come to indicate solid popular approval of maintenance of armament and participation in alliance.

Linking the wellness and health sectors could increase program availability. We evaluated if people with OA were willing to participate in programs delivered by trainers in community centers/gyms. Methods: We conducted an online survey of the general public in Canada over a period of 2 months. Participants included those aged ≥30 years with self-reported chronic OA-like knee or hip pain. We evaluated access to community/fitness centers, exercise frequency, interest in attending an evidence-based program twice a week for 6 weeks, and willingness to pay. Analyses included descriptive statistics with 95% confidence intervals and chi-square tests to evaluate factors associated with willingness to attend the program. Results: After removing duplicate records, 751 respondents completed the survey with 408 likely having hip and/or knee OA and never having received a joint replacement. These 408 respondents had an age range of 30 to ≥75 years and 86% were female. Of the 408, (63.7% were between 45 and 64 years of age. Only two respondents reported that a community center was >1 hour away. One hundred and fifty-six (38% reported a current membership, and 203 (50.4% reported exercise 3 days/wk, 120 (29.8% <3 days, and 80 (19.9% reported no exercise. Two

    Surgical site infections (SSI) continue to be a significant problem in surgery. The American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) Best Practices Initiative compared process and structural characteristics among 117 private sector hospitals in an effort to define best practices aimed at preventing SSI. Using standard NSQIP methodologies, we identified 20 low outlier and 13 high outlier hospitals for SSI using data from the ACS-NSQIP in 2006. Each hospital was administered a process of care survey, and site visits were conducted to five hospitals. Comparisons between the low and high outlier hospitals were made with regard to patient characteristics, operative variables, structural variables, and processes of care. Hospitals that were high outliers for SSI had higher trainee-to-bed ratios (0.61 versus 0.25, p site visitors. Overall, low outlier hospitals were smaller, efficient in the delivery of care, and experienced little operative staff turnover. Our findings suggest that evidence-based SSI prevention practices do not easily distinguish well from poorly performing hospitals. But structural and process of care characteristics of hospitals were found to have a significant association with good results.

    Residents in our country have achieved a homogenous surgical training by following a structured residency program. This is due to the existence of specific training programs for each specialty. The current program, approved in 2007, has a detailed list of procedures that a surgeon should have performed in order to complete training. The aim of this study is to analyze the applicability of the program with regard to the number of procedures performed during the residency period. A data collection form was designed that included the list of procedures from the program of the specialty; it was sent in April 2014 to all hospitals with accredited residency programs. In September 2014 the forms were analysed, and a general descriptive study was performed; a subanalysis according to the resident's sex and Autonomous region was also performed. The number of procedures performed according to the number of residents in the different centers was also analyzed. The survey was sent to 117 hospitals with accredited programs, which included 190 resident places. A total of 91 hospitals responded (53%). The training offered adapts in general to the specialty program. The total number of procedures performed in the different sub-areas, in laparoscopic and emergency surgery is correct or above the number recommended by the program, with the exception of esophageal-gastric and hepatobiliary surgery. The sub-analysis according to Autonomous region did not show any significant differences in the total number of procedures, however, there were significant differences in endocrine surgery (P=.001) and breast surgery (P=.042). A total of 55% of residents are female, with no significant differences in distribution in Autonomous regions. However, female surgeons operate more than their male counterparts during the residency period (512±226 vs. 625±244; P<.01). The number of residents in the hospital correlates with the number of procedures performed; the residents with more procedures

    Risk models to predict 30-day mortality following isolated coronary artery bypass graft is an active area of research. Simple risk predictors are particularly important for cardiothoracic surgeons who are coming under increased scrutiny since these physicians typically care for higher risk patients and thus expect worse outcomes. The objective of this study was to develop a 30-day postoperative mortality risk model for patients undergoing CABG using the American College of Surgeons National Surgical Quality Improvement Program database. Data was extracted and analyzed from the American College of Surgeons National Surgical Quality Improvement Program Participant Use Files (2005-2010). Patients that had ischemic heart disease (ICD9 410-414) undergoing one to four vessel CABG (CPT 33533-33536) were selected. To select for acquired heart disease, only patients age 40 and older were included. Multivariate logistic regression analysis was used to create a risk model. The C-statistic and the Hosmer-Lemeshow goodness-of-fit test were used to evaluate the model. Bootstrap-validated C-statistic was calculated. A total of 2254 cases met selection criteria. Forty-nine patients (2.2%) died within 30 days. Six independent risk factors predictive of short-term mortality were identified including age, preoperative sodium, preoperative blood urea nitrogen, previous percutaneous coronary intervention, dyspnea at rest, and history of prior myocardial infarction. The C-statistic for this model was 0.773 while the bootstrap-validated C-statistic was 0.750. The Hosmer-Lemeshow test had a p-value of 0.675, suggesting the model does not overfit the data. The American College of Surgeons National Surgical Quality Improvement Program risk model has good discrimination for 30-day mortality following coronary artery bypass graft surgery. The model employs six independent variables, making it easy to use in the clinical setting.

    "What other people think" has always been an important piece of information during various decision-making processes. Today people frequently make their opinions available via the Internet, and as a result, the Web has become an excellent source for gathering consumer opinions. There are now numerous Web resources containing such opinions, e.g., product reviews forums, discussion groups, and Blogs. But, due to the large amount of information and the wide range of sources, it is essentially impossible for a customer to read all of the reviews and make an informed decision on whether to purchase the product. It is also difficult for the manufacturer or seller of a product to accurately monitor customer opinions. For this reason, mining customer reviews, or opinion mining, has become an important issue for research in Web information extraction. One of the important topics in this research area is the identification of opinion polarity. The opinion polarity of a review is usually expressed with values 'positive'...

  8. Opinion dynamics with confirmation bias.

    Allahverdyan, Armen E; Galstyan, Aram

    2014-01-01

    Confirmation bias is the tendency to acquire or evaluate new information in a way that is consistent with one's preexisting beliefs. It is omnipresent in psychology, economics, and even scientific practices. Prior theoretical research of this phenomenon has mainly focused on its economic implications possibly missing its potential connections with broader notions of cognitive science. We formulate a (non-Bayesian) model for revising subjective probabilistic opinion of a confirmationally-biased agent in the light of a persuasive opinion. The revision rule ensures that the agent does not react to persuasion that is either far from his current opinion or coincides with it. We demonstrate that the model accounts for the basic phenomenology of the social judgment theory, and allows to study various phenomena such as cognitive dissonance and boomerang effect. The model also displays the order of presentation effect-when consecutively exposed to two opinions, the preference is given to the last opinion (recency) or the first opinion (primacy) -and relates recency to confirmation bias. Finally, we study the model in the case of repeated persuasion and analyze its convergence properties. The standard Bayesian approach to probabilistic opinion revision is inadequate for describing the observed phenomenology of persuasion process. The simple non-Bayesian model proposed here does agree with this phenomenology and is capable of reproducing a spectrum of effects observed in psychology: primacy-recency phenomenon, boomerang effect and cognitive dissonance. We point out several limitations of the model that should motivate its future development.

    Chondroblastoma of bone is rare bone tumor, representing around 1% of benign bone lesions. It is considered a benign lesion, although primary malignant form as well as malignant alteration in the form of chondrosarcoma has been documented. It occurs predominantly in the second decade, more commonly in males. Predilection sites include proximal humeral epiphysis, femoral and tibial condyles, but it can be found in other bones, too (skull, pelvis, posterior vertebral structures, tarsal bones). Radiographically, it appears as an ovoid lesion with thin sclerotic margin, located centrally in the epiphysis. Pathohistologically, it is described as highly cellular tissue, variably differentiated and with discrete granulated to meshy calcification of the matrix and large multinuclear cells present in 20% of cases. Secondary formation of aneurysmal bone cyst has been documented. Tumor is presented with a few nonspecific local symptoms, which makes diagnostic procedure more difficult. Definitive diagnosis is made only by pathohistological verification. A pathological fracture of weakened epiphysis is possible. The treatment of chondroblastoma is strictly surgical, with a view to counteract the propagation into the joint or adjacent soft tissue, and diminish the recurrence rate. Chemotherapy is not indicated for treatment of this tumor, and radiotherapy is contraindicated as it stimulates malignant alteration. If malignant chondroblastoma of bone is verified pathohistologically, radical treatment by surgical resection is indicated, also avoiding any adjuvant therapy.

    Aiming at the weight of trust someone given to participate in the interaction in Hegselmann-Krause's type consensus model is the same and virtual social networks among individuals with different level of education, personal influence, etc. For differences between agents, a novelty bounded confidence model was proposed with leader's opinion considered priority. Interaction neighbors can be divided into two kinds. The first kind is made up of "opinion leaders" group, another kind is made up of ordinary people. For different groups to give different weights of trust. We also analyzed the related characteristics of the new model under the symmetrical bounded confidence parameters and combined with the classical HK model were analyzed. Simulation experiment results show that no matter the network size and initial view is subject to uniform distribution or discrete distribution. We can control the "opinion-leader" good change the number of views and values, and even improve the convergence speed. Experiment also found that the choice of "opinion leaders" is not the more the better, the model well explain how the "opinion leader" in the process of the evolution of the public opinion play the role of the leader.

    Inter-professional collaboration is an integral component of a successful healthcare team. We sought to evaluate the impact of nursing student participation in a one-day intensive inter-professional education (IPE) training session with surgical interns on participant attitudes toward inter-professional collaboration. Following IRB approval, pre and post IPE session survey responses were compared to determine the impact on participant attitudes toward inter-professional collaboration. Pre and post session semi-structured interviews were transcribed and analyzed to identify relevant themes. Surgical interns (n = 38) more than nursing students (n = 11), demonstrated a measurable improvement in attitude towards 'collaboration and shared education' (interns: median score pre = 26, post = 28, p = 0.0004; nursing student: median score pre = 27, post = 28, p = 0.02). Qualitative analysis of interviews identified major themes that supplemented this finding. An eight hour, one day IPE session has a positive impact on collaborative attitudes and supports the case for increased inter-professional education amongst interns and nursing students.

    We introduce a novel type of contrarian agent, the balancer, to Galam model of opinion dynamics, in order to account for the skepticism over one-sidedness and for the sense of fairness. We find that the inclusion of balancers along with floaters and inflexibles brings about a critical point on parametric plane of the dynamical system, which results in the new kind of stable final states of the opinion dynamics, that seem to capture several intriguing features found often in mature democracies.

    The purpose of this study was to assess for compounded risk of postoperative morbidity with the addition of a simultaneous contralateral breast matching procedure at the time of mastectomy and immediate breast reconstruction. 2005 to 2012 American College of Surgeons National Surgical Quality Improvement Program databases were used to identify cases of mastectomy and immediate breast reconstruction with and without simultaneous contralateral breast matching procedures. Matching procedures included mastopexy, reduction mammaplasty, and augmentation mammaplasty. Thirty-day postoperative morbidity was assessed using univariable and multivariable logistic regression. Of 59,766 mastectomy patients, 24,191 (40 percent) underwent immediate breast reconstruction: 903 (3.7 percent) underwent matching procedures and 23,288 (96.3 percent) did not. Univariable logistic regression demonstrated that the matching procedure group had statistically significantly higher overall morbidity (OR, 1.288; 95 percent CI, 1.022 to 1.623; p = 0.032). Although surgical and systemic morbidity did not differ significantly, the matching procedure group demonstrated higher risk for superficial surgical-site infection (OR, 1.57; 95 percent CI, 1.066 to 2.31; p = 0.022), reconstruction failure (OR, 1.69; 95 percent CI, 1.014 to 2.814; p = 0.044), and pulmonary embolism (OR, 2.54; 95 percent CI, 1.01 to 6.37; p = 0.048). Controlling for possible confounders, multivariable logistic regression rendered the relationship between matching procedure and complications insignificant (OR, 1.17; 95 percent CI, 0.92 to 1.48; p = 0.2). These data suggest that preoperative comorbidities and other patient-related factors may have a larger influence on postoperative morbidity than the addition of a contralateral matching procedure alone.

  19. Opinion Dynamics with Confirmation Bias

    Allahverdyan, Armen E.; Galstyan, Aram

    2014-01-01

    Background Confirmation bias is the tendency to acquire or evaluate new information in a way that is consistent with one's preexisting beliefs. It is omnipresent in psychology, economics, and even scientific practices. Prior theoretical research of this phenomenon has mainly focused on its economic implications possibly missing its potential connections with broader notions of cognitive science. Methodology/Principal Findings We formulate a (non-Bayesian) model for revising subjective probabilistic opinion of a confirmationally-biased agent in the light of a persuasive opinion. The revision rule ensures that the agent does not react to persuasion that is either far from his current opinion or coincides with it. We demonstrate that the model accounts for the basic phenomenology of the social judgment theory, and allows to study various phenomena such as cognitive dissonance and boomerang effect. The model also displays the order of presentation effect–when consecutively exposed to two opinions, the preference is given to the last opinion (recency) or the first opinion (primacy) –and relates recency to confirmation bias. Finally, we study the model in the case of repeated persuasion and analyze its convergence properties. Conclusions The standard Bayesian approach to probabilistic opinion revision is inadequate for describing the observed phenomenology of persuasion process. The simple non-Bayesian model proposed here does agree with this phenomenology and is capable of reproducing a spectrum of effects observed in psychology: primacy-recency phenomenon, boomerang effect and cognitive dissonance. We point out several limitations of the model that should motivate its future development. PMID:25007078

    Superficial surgical site infection (sSSI) is one of the most common complications after colorectal resection. The goal of this study was to determine the comorbidities and operative characteristics that place patients at risk for sSSI in patients who underwent rectal cancer resection. The American College of Surgeons National Surgical Quality Improvement Program database was queried (via diagnosis and Current Procedural Terminology codes) for patients with rectal cancer who underwent elective resection between 2005 and 2012. Patients for whom data concerning 27 demographic factors, comorbidities, and operative characteristics were available were eligible. A univariate and multivariate analysis was performed to identify possible risk factors for sSSI. A total of 8880 patients met the entry criteria and were included. sSSIs were diagnosed in 861 (9.7%) patients. Univariate analysis found 14 patients statistically significant risk factors for sSSI. Multivariate analysis revealed the following risk factors: male gender, body mass index (BMI) >30, current smoking, history of chronic obstructive pulmonary disease (COPD), American Society of Anesthesiologists III/IV, abdominoperineal resection (APR), stoma formation, open surgery (versus laparoscopic), and operative time >217 min. The greatest difference in sSSI rates was noted in patients with COPD (18.9 versus 9.5%). Of note, 54.2% of sSSIs was noted after hospital discharge. With regard to the timing of presentation, univariate analysis revealed a statistically significant delay in sSSI presentation in patients with the following factors and/or characteristics: BMI Multivariate analysis suggested that only laparoscopic surgery (versus open) and preoperative RT were risk factors for delay. Rectal cancer resections are associated with a high incidence of sSSIs, over half of which are noted after discharge. Nine patient and operative characteristics, including smoking, BMI, COPD, APR, and open surgery were found to be

    Full Text Available The essay analyzes the conflict which opened after the French Revolution between public opinion and ideology. In this space of reflection the second seemed sometimes as the hidden face of the first one. Public opinion historically represented the institutionalization of the possibility of a disagreement on the legitimacy of the body politic. It has thus made possible a speech on the political detached from religion. As is clear from the controversy of Napoleon against the ideologues and the Marxian critique, ideology does not get to be the science of social discourse and its alienation, to become a set of sophistry on social conditions. Discussing the arguments of Tocqueville, Bourdieu and Reynié about the deficit of reflexivity of public opinion, the author affirms its distance from the ideology, because it requires anyway an investment for religious believe his propositions.

    To design and implement a teaching skills curriculum that addressed the needs of an ophthalmology residency training program, to assess the effect of the curriculum, and to present important lessons learned. A teaching skills curriculum was designed for the Harvard Medical School (HMS) Residency Training Program in Ophthalmology. Results of a needs assessment survey were used to guide curriculum objectives. Overall, 3 teaching workshops were conducted between October 2012 and March 2013 that addressed areas of need, including procedural teaching. A postcurriculum survey was used to assess the effect of the curriculum. Massachusetts Eye and Ear Infirmary, a tertiary care institution in Boston, MA. Overall, 24 residents in the HMS Residency Training Program in Ophthalmology were included. The needs assessment survey demonstrated that although most residents anticipated that teaching would be important in their future career, only one-third had prior formal training in teaching. All residents reported they found the teaching workshops to be either very or extremely useful. All residents reported they would like further training in teaching, with most residents requesting additional training in best procedural teaching practices for future sessions. The pilot year of the resident-as-teacher curriculum for the HMS Residency Training Program in Ophthalmology demonstrated a need for this curriculum and was perceived as beneficial by the residents, who reported increased comfort in their teaching skills after attending the workshops.

    Fan, Kangqi; Pedrycz, Witold

    2016-11-01

    Guiding public opinions toward a pre-set target by informed agents can be a strategy adopted in some practical applications. The informed agents are common agents who are employed or chosen to spread the pre-set opinion. In this work, we propose a social judgment based opinion (SJBO) dynamics model to explore the opinion evolution under the influence of informed agents. The SJBO model distinguishes between inner opinions and observable choices, and incorporates both the compromise between similar opinions and the repulsion between dissimilar opinions. Three choices (support, opposition, and remaining undecided) are considered in the SJBO model. Using the SJBO model, both the inner opinions and the observable choices can be tracked during the opinion evolution process. The simulation results indicate that if the exchanges of inner opinions among agents are not available, the effect of informed agents is mainly dependent on the characteristics of regular agents, including the assimilation threshold, decay threshold, and initial opinions. Increasing the assimilation threshold and decay threshold can improve the guiding effectiveness of informed agents. Moreover, if the initial opinions of regular agents are close to null, the full and unanimous consensus at the pre-set opinion can be realized, indicating that, to maximize the influence of informed agents, the guidance should be started when regular agents have little knowledge about a subject under consideration. If the regular agents have had clear opinions, the full and unanimous consensus at the pre-set opinion cannot be achieved. However, the introduction of informed agents can make the majority of agents choose the pre-set opinion.

    2016-01-01

    Solicited public opinion surveys reach a limited subpopulation of willing participants and are expensive to conduct, leading to poor time resolution and a restricted pool of expert-chosen survey topics. In this study, we demonstrate that unsolicited public opinion polling through sentiment analysis applied to Twitter correlates well with a range of traditional measures, and has predictive power for issues of global importance. We also examine Twitter's potential to canvas topics seldom surveyed, including ideas, personal feelings, and perceptions of commercial enterprises. Two of our major observations are that appropriately filtered Twitter sentiment (1) predicts President Obama's job approval three months in advance, and (2) correlates well with surveyed consumer sentiment. To make possible a full examination of our work and to enable others' research, we make public over 10,000 data sets, each a seven-year series of daily word counts for tweets containing a frequently used search term.

    To evaluate pregnancy rates with letrozole and clomiphene citrate (CC) alone for superovulation in an intrauterine insemination program for women with recently surgically treated minimal to mild endometriosis. A randomized controlled trial following the CONSORT criteria. University teaching hospital and a private practice setting. 136 women with primary infertility due to minimal to mild endometriosis who did not achieve pregnancy after six to 12 months following laparoscopic treatment. Superovulation using 5 mg letrozole/day (69 women, 220 cycles) or 100 mg CC/day (67 women, 213 cycles) for five days combined with intrauterine insemination up to four cycles. Clinical pregnancy rate per cycle, cumulative pregnancy rate after four cycles, number of follicles, serum estradiol, endometrial thickness on the day of human chorionic gonadotropin administration, serum progesterone, miscarriage and live birth rates. The clinical pregnancy rate per cycle and the cumulative pregnancy rate after four cycles were comparable (15.9 vs. 14.5% and 64.7 vs. 57.2%; p=0.82, p=0.71 in letrozole and CC groups, respectively). Two twin pregnancies occurred in the CC/intrauterine insemination group. Miscarriage and live birth rates were comparable (11.4 vs. 12.9% and 44.9 vs. 40.3%; p=0.47, p=0.62 in letrozole and CC groups, respectively). The total number of follicles and serum estradiol on the day of human chorionic gonadotropin administration were significantly increased in the CC group. Superovulation with letrozole is not more effective than clomiphene citrate alone in an intrauterine insemination program for women with minimal to mild endometriosis who did not achieve pregnancy after six to 12 months following laparoscopic treatment.

    2014-08-01

    Full Text Available In this paper, we describe a set of reusable text processing components for extracting opinionated information from social media, rating it for interestingness, and for detecting opinion events. We have developed applications in GATE to extract named entities, terms and events and to detect opinions about them, which are then used as the starting point for opinion event detection. The opinions are then aggregated over larger sections of text, to give some overall sentiment about topics and documents, and also some degree of information about interestingness based on opinion diversity. We go beyond traditional opinion mining techniques in a number of ways: by focusing on specific opinion-target extraction related to key terms and events, by examining and dealing with a number of specific linguistic phenomena, by analysing and visualising opinion dynamics over time, and by aggregating the opinions in different ways for a more flexible view of the information contained in the documents.

A new philosophy, relationship marketing, is taking over the position of the old transaction marketing philosophy. The greatest challenge for marketing professionals at the beginning of the 21st century is this third dimension of relationships - relations between consumers, their mutual impact on preferences and purchase decisions, and, most notably, the possibility of involving consumers in companies marketing mix programs.

    OBJECTIVE Hospital readmission rate is increasingly used as a quality outcome measure after surgery. The purpose of this study was to establish, using a national database, the baseline readmission rates and risk factors for patient readmission after pediatric neurosurgical procedures. METHODS The American College of Surgeons National Surgical Quality Improvement Program-Pediatric database was queried for pediatric patients treated by a neurosurgeon between 2012 and 2013. Procedures were categorized by current procedural terminology (CPT) code. Patient demographics, comorbidities, preoperative laboratory values, operative variables, and postoperative complications were analyzed via univariate and multivariate techniques to find associations with unplanned readmissions within 30 days of the primary procedure. RESULTS A total of 9799 cases met the inclusion criteria, 1098 (11.2%) of which had an unplanned readmission within 30 days. Readmission occurred 14.0 ± 7.7 days postoperatively (mean ± standard deviation). The 4 procedures with the highest unplanned readmission rates were CSF shunt revision (17.3%; CPT codes 62225 and 62230), repair of myelomeningocele > 5 cm in diameter (15.4%), CSF shunt creation (14.1%), and craniectomy for infratentorial tumor excision (13.9%). The lowest unplanned readmission rates were for spine (6.5%), craniotomy for craniosynostosis (2.1%), and skin lesion (1.0%) procedures. On multivariate regression analysis, the odds of readmission were greatest in patients experiencing postoperative surgical site infection (SSI; deep, organ/space, superficial SSI, and wound disruption: OR > 12 and p 10 days (OR 1.411, p = 0.010), oxygen supplementation (OR 1.645, p = 0.010), nutritional support (OR 1.403, p = 0.009), seizure disorder (OR 1.250, p = 0.021), and longer operative time (per hour increase, OR 1.059, p = 0.029). CONCLUSIONS This study may aid in identifying patients at risk for unplanned readmission following pediatric neurosurgery

However,another factor that is enlarging the inter-industry gap is always missed,that is,the income disparity within the industry.

    Credit Cards Not Candy Nowadays, colleges and universities have become a big market for many banks and competition is fierce. At the start of every new semester, numerous banks will send their staff to promote credit cards among college students and some students even havetwo or three credit cards.As long as they are able to pay off theiroverdraft, it’s acceptable to give college stu-dents credit cards. However, students don’have stable incomes. By targeting this group banks have to lower the threshold for cardapplications. Sometimes, they even do nocheck student applicants’ repayment capa-bilities. An important reason for this practiceis that banks know behind the students aretheir parents. If students can’t pay back thecredit, banks will turn to the parents to make good the outstanding amounts.

    2015-01-01

    We propose and investigate different kinetic models for opinion formation, when the opinion formation process depends on an additional independent variable, e.g. a leadership or a spatial variable. More specifically, we consider:(i) opinion dynamics under the effect of opinion leadership, where each individual is characterised not only by its opinion, but also by another independent variable which quantifies leadership qualities; (ii) opinion dynamics modelling political segregation in the `The Big Sort', a phenomenon that US citizens increasingly prefer to live in neighbourhoods with politically like-minded individuals. Based on microscopic opinion consensus dynamics such models lead to inhomogeneous Boltzmann-type equations for the opinion distribution. We derive macroscopic Fokker-Planck-type equations in a quasi-invariant opinion limit and present results of numerical experiments.

    Background Red blood cell transfusions (RBCT) carry risk of transfusion-related immunodulation that may impact postoperative recovery. This study examined the association between perioperative RBCT and short-term postoperative outcomes following gastrectomy for gastric cancer. Methods Using the American College of Surgeons National Surgical Quality Improvement Program database, we compared outcomes of patients (transfused v. nontransfused) undergoing elective gastrectomy for gastric cancer (2007–2012). Outcomes were 30-day major morbidity, mortality and length of stay. The association between perioperative RBCT and outcomes was estimated using modified Poisson, logistic, or negative binomial regression. Results Of the 3243 patients in the entire cohort, we included 2884 patients with nonmissing data, of whom 535 (18.6%) received RBCT. Overall 30-day major morbidity and mortality were 20% and 3.5%, respectively. After adjustment for baseline and clinical characteristics, RBCT was independently associated with increased 30-day mortality (relative risk [RR] 3.1, 95% confidence interval [CI] 1.9–5.0), major morbidity (RR 1.4, 95% CI 1.2–1.8), length of stay (RR 1.2, 95% CI 1.1–1.2), infections (RR 1.4, 95% CI 1.1–1.6), cardiac complications (RR 1.8, 95% CI 1.0–3.2) and respiratory failure (RR 2.3, 95% CI 1.6–3.3). Conclusion Red blood cell transfusions are associated with worse postoperative short-term outcomes in patients with gastric cancer. Blood management strategies are needed to reduce the use of RBCT after gastrectomy for gastric cancer. PMID:27668330

    There has been an increasing use of national databases to conduct orthopaedic research. Questions regarding the validity and consistency of these studies have not been fully addressed. The purpose of this study was to test for similarity in reported measures between two national databases commonly used for orthopaedic research. A retrospective cohort study of patients undergoing lumbar spinal fusion procedures during 2009 to 2011 was performed in two national databases: the Nationwide Inpatient Sample and the National Surgical Quality Improvement Program. Demographic characteristics, comorbidities, and inpatient adverse events were directly compared between databases. The total numbers of patients included were 144,098 from the Nationwide Inpatient Sample and 8434 from the National Surgical Quality Improvement Program. There were only small differences in demographic characteristics between the two databases. There were large differences between databases in the rates at which specific comorbidities were documented. Non-morbid obesity was documented at rates of 9.33% in the Nationwide Inpatient Sample and 36.93% in the National Surgical Quality Improvement Program (relative risk, 0.25; p databases in the rates at which specific inpatient adverse events were documented. Sepsis was documented at rates of 0.38% in the Nationwide Inpatient Sample and 0.81% in the National Surgical Quality Improvement Program (relative risk, 0.47; p database studies become more prevalent in orthopaedic surgery, authors, reviewers, and readers should view these studies with caution. This study shows that two commonly used databases can identify demographically similar patients undergoing a common orthopaedic procedure; however, the databases document markedly different rates of comorbidities and inpatient adverse events. The differences are likely the result of the very different mechanisms through which the databases collect their comorbidity and adverse event data. Findings highlight

    Ease of handling and control in zero gravity and minimizing the quantity of water required were prime considerations. The program tasks include the selection of biocidal agent from among the variety used for surgical scrub, formulation of a dispensing system, test, and delivery of flight dispensers. The choice of an iodophore was based on effectiveness on single applications, general familiarity among surgeons, and previous qualification for space use. The delivery system was a choice between the squeeze foamer system and impregnated polyurethane foam pads. The impregnated foam pad was recommended because it is a simpler system since the squeeze foamer requires some applicator to effectively clean the skin surfaces, whereas the form pad is the applicator and agent combined. Testing demonstrated that both systems are effective for use as surgical scrubs.

  1. Opinion dynamics with disagreement and modulated information

    2012-01-01

    Opinion dynamics concerns social processes through which populations or groups of individuals agree or disagree on specific issues. As such, modelling opinion dynamics represents an important research area that has been progressively acquiring relevance in many different domains. Existing approaches have mostly represented opinions through discrete binary or continuous variables by exploring a whole panoply of cases: e.g. independence, noise, external effects, multiple issues. In most of these cases the crucial ingredient is an attractive dynamics through which similar or similar enough agents get closer. Only rarely the possibility of explicit disagreement has been taken into account (i.e., the possibility for a repulsive interaction among individuals' opinions), and mostly for discrete or 1-dimensional opinions, through the introduction of additional model parameters. Here we introduce a new model of opinion formation, which focuses on the interplay between the possibility of explicit disagreement, modulate...

    Breast cancer pathology reports contain valuable information about the histologic diagnosis, prognostic factors and predictive indicators of therapeutic response. A second opinion may be requested by medical oncologists and surgeons, when a patient is referred from another institution for treatment. We report the experience with pathology second opinion in selected patients referred to the Breast Oncology Unit. 205 cases referred to the Breast Oncology Unit were selected for second opinion after clinical evaluation, between 2002 and 2012. The cases reviewed included 102 core needle biopsies, 88 surgical specimens from the breast and 18 lymphadenopathies, 14 from the axillary region. Pathology second opinion was based on a review of hematoxylin-eosin preparations, recuts of submitted paraffin blocks and written external pathology reports. Immunohistochemical studies for hormone receptors, HER2, myoepithelial cells, and other markers were performed in selected cases. A case was reclassified as showing major change when second opinion showed a potential for significant change in prognosis or treatment. Otherwise, it was considered to represent minor change or to be concordant. In 52 cases (25.4%), the pathology review showed changes. Thirty-three (16%) patients were reclassified for major changes and 19 (9.2%) as minor changes. In six patients, more than one major change was identified. The major discrepancies identified were related to the histologic classification (12 cases), the presence or absence of invasion in ductal carcinoma (15 cases), the results of hormone receptors (5 cases), and HER2 (7 cases). Major changes in histologic classification included two cases diagnosed as invasive ductal carcinoma and reclassified as benign, four cases with diagnosis of breast cancer reclassified as metastatic lung cancer, one case diagnosed as small cell carcinoma of lung metastatic in the breast, reclassified as primary carcinoma of the breast, and three cases with

    Full Text Available The purpose of this study is to evaluate a pedagogical formation program based on the opinions of the pre-service teachers taking it. The study group consists of 36 pre-service teachers from the departments of Turkish Language and Literature, German Language, Philosophy, Mathematics, History and Physics who are participating in the Pedagogical Formation Certificate Program of Muğla Sıtkı Koçman University, Turkey. The study was conducted by using the qualitative research method. A semi-structured interview form was developed by the researchers to collect the data. The pre-service teachers’ opinions about the pedagogical formation program were elicited through the focus group interview method. The collected data were analyzed through content analysis, one of the qualitative research techniques. The results of the analysis revealed that although the pre-service teachers think that giving formation education to the graduates of the Faculty of Science and Letters is positive, this education would be best given at the same time with their undergraduate education in an applied way. The most significant problems experienced by the pre-service teachers throughout the program were stated to be that the program is given over a very short timeframe, that traditional lecturing is adopted as the primary means of instruction and that a lot of information is tried to be given in a short time. Moreover, the pre-service teachers stated that the classrooms are very crowded and the education faculty does not have the required tools and equipment, which adversely affects the quality of the educational process. Finally, they stressed that the Public Personnel Selection Examination (KPSS is quite inadequate to evaluate teachers’ competencies and that an application-based evaluation would be better suited.

    Pluchino, Alessandro; Latora, Vito; Rapisarda, Andrea

    We propose a new model of opinion formation, the Opinion Changing Rate (OCR) model. Instead of investigating the conditions that allow consensus in a world of agents with different opinions, we study the conditions under which a group of agents with different natural tendency (rate) to change opinion can find agreement. The OCR is a modified version of the Kuramoto model, one of the simplest models for synchronization in biological systems, adapted here to a social context. By means of several numerical simulations, we illustrate the richness of the OCR model dynamics and its social implications.

    Full Text Available Hepatocellular carcinoma (HCC is an epithelial tumor derived from hepatocytes; it accounts for 80% of all primary liver cancers and ranks globally as the fourth leading cause of cancer-related deaths. HCC treatment is a multidisciplinary and a multimodal task, with surgery in the form of liver resection and liver transplantation (LT representing the only potentially curative modality. However, there are variable opinions and discussions about applying these surgical options and using other supporting treatments. This article is a narrative review that includes articles published from 1984 to 2013 located by searching scientific databases such as PubMed, SCOPUS, and Elsevier, with the main keyword of hepatocellular carcinoma in addition to other keywords such as liver transplantation, liver resection, transarterial chemoembolization, portal vein embolization, bridging therapy, and downstaging. In this review, we focus mainly on the surgical treatment options offered for HCC, in order to illustrate the current relevant data available in the literature to help in applying these surgical options and to use other supporting treatment modalities when appropriate.

A lesson from social psychology gives reason to believe that people, with negligible exceptions, assess and navigate socially on the basis of what other people express to believe or know. This is in line...... with the principle of social proof (Cialdini 2009) – referring to the group dynamics that are created when people make decisions upon what they believe other people believe or know.

    Wybaillie, E; Broos, P L O

    2010-01-01

    An accident and emergency (A&E) training has been suggested as an essential part of the basic surgical training. The A&E curriculum should be divided into three sections: a critical curriculum, a core curriculum and a comprehensive curriculum. For instance, the critical curriculum contains topics that provide the opportunity to translate the ABCDE principles of trauma management into practice. Furthermore, a post in the A&E department provides the surgical trainee with significant exposure to the management of the polytrauma patient and to the management of other acute general surgical, urological and orthopaedic conditions. By presenting better educational programs and by reducing the non-medical tasks a trainee has to deal with, the education of surgical trainees during A&E attachment can be improved.

    BACKGROUND: On the 1 August 2009, the implementation of European Working Time Directive became European law and was implemented in Galway University Hospital (GUH). AIMS: The aim of the study is to ascertain the opinion of the 25 surgical SHOs in GUH on the effect of the implementation of an EWTD compliant roster had on the quality of their training. METHODS: A questionnaire was circulated to all 25 surgical SHOs. RESULTS: Twenty-two (88%) SHOs report a reduction in the quality of their training. 18 (72%) report a reduction in the development of their operative skills. The SHOs believed the EWTD Rotas would encourage Irish graduates to train abroad. CONCLUSIONS: Surgical training faces a challenge with the implementation of EWTD Rotas. Major changes need to be made to the surgical training structure to train surgeons to the highest standard and to retain Irish-trained surgeons in the Irish healthcare system.

    Full Text Available Abstract Background Second opinion is a treatment ratification tool that may critically influence diagnosis, treatment, and prognosis. Second opinions constitute one of the largest expenditures of the supplementary health insurance programs provided by the Israeli health funds. The scarcity of data on physicians’ attitudes toward second opinion motivated this study to explore those attitudes within the Israeli healthcare system. Methods We interviewed 35 orthopedic surgeons and neurologists in Israel and qualitatively analyzed the data using the Grounded Theory approach. Results As a common tool, second opinion reflects the broader context of the Israeli healthcare system, specifically tensions associated with health inequalities. We identified four issues: (1 inequalities between central and peripheral regions of Israel; (2 inequalities between private and public settings; (3 implementation gap between the right to a second opinion and whether it is covered by the National Health Insurance Law; and (4 tension between the authorities of physicians and religious leaders. The physicians mentioned that better mechanisms should be implemented for guiding patients to an appropriate consultant for a second opinion and for making an informed choice between the two opinions. Conclusions While all the physicians agreed on the importance of the second opinion as a tool, they raised concerns about the way it is provided and utilized. To be optimally implemented, second opinion should be institutionalized and regulated. The National Health Insurance Law should strive to provide the mechanisms to access second opinion as stipulated in the Patient’s Rights Law. Further studies are needed to assess the patients' perspectives.

    Michael T Gastner

    Full Text Available Statistical physicists have become interested in models of collective social behavior such as opinion formation, where individuals change their inherently preferred opinion if their friends disagree. Real preferences often depend on regional cultural differences, which we model here as a spatial gradient g in the initial opinion. The gradient does not only add reality to the model. It can also reveal that opinion clusters in two dimensions are typically in the standard (i.e., independent percolation universality class, thus settling a recent controversy about a non-consensus model. However, using analytical and numerical tools, we also present a model where the width of the transition between opinions scales proportional g(-1/4, not proportional g(-4/7 as in independent percolation, and the cluster size distribution is consistent with first-order percolation.

    Full Text Available Opinion Mining is related to detect the opinion of the author expressed in the document. The primary task in the field of opinion Mining is Subjectivity Analysis which finds whether the document is subjective or objective. Subjectivity shows that the document contains some opinionated part, while the objectivity shows thatthe document is far behind from the opinionated part i.e. it has no sentiments containing. The next task is Sentiment Polarity Analysis which differentiates the documents according to positivity and negativity. But presently there is no automated system which can perform this task. We are developing a system which can findthe degree of polarity of each document and according to it assign a human like rating to that document. At last it generates the summary of review which contains only the highly subjective and feature related part of the document.

    We describe the development of a medical student surgical interest group, its initial evaluation, and future plans. The Surgical Students Society of Melbourne was formed in August 2008 by a group of senior medical students from the University of Melbourne. The Surgical Students Society of Melbourne seeks to provide additional surgical teaching and professional development for students interested in a career in surgery. It also aims to provide junior doctors with leadership and teaching opportunities to meet the requirements of the Royal Australasian College of Surgeons for application to the Surgical Education and Training program. Its program also addresses contemporary workforce issues, such as women in surgery and rural surgery. The society runs a weekly teaching program during the semester and procedural and careers workshops throughout the year. A survey of students attending the teaching program was conducted by means of written and online questionnaires. The results suggest that the society has been successful in augmenting surgical education and providing opportunities to improve procedural skills, but also highlighted areas of the program that may be improved, including aspects of surgical professional development and role modeling. The Surgical Students Society initiative was generally very well received by students and shows great potential as a means for augmenting surgical education at the medical student level.

    -length studies of Swedish mass attitudes toward nuclear power appeared already in the late 1970-ies. Since then all SNES surveys have included measurements of Swedish opinions on various energy issues. A special election study was done in 1980 covering the nuclear power referendum. Beginning in 1986, SNES's election year measurements were supplemented by annual studies done by the newly founded SOM Institute at Univ. of Gothenburg. These annual measurements were from the start designed and coordinated by the research project Energy Opinion in Sweden, originally financially supported by the now non-existent National Board for Spent Fuel, but since 1999 financed by The Swedish Energy Agency. The analyses in the chapters in this English language book compendium have all been done and published under the auspices of the research project Energy Opinion in Sweden. The time span is quite long, over twenty years. The writing in Chapter 1 appeared already in 1991, while the results in Chapters 7 and 8 are from 2011.

  6. Choice Shift in Opinion Network Dynamics

    Science.gov (United States)

    Gabbay, Michael

    Choice shift is a phenomenon associated with small group dynamics whereby group discussion causes group members to shift their opinions in a more extreme direction so that the mean post-discussion opinion exceeds the mean pre-discussion opinion. Also known as group polarization, choice shift is a robust experimental phenomenon and has been well-studied within social psychology. In opinion network models, shifts toward extremism are typically produced by the presence of stubborn agents at the extremes of the opinion axis, whose opinions are much more resistant to change than moderate agents. However, we present a model in which choice shift can arise without the assumption of stubborn agents; the model evolves member opinions and uncertainties using coupled nonlinear differential equations. In addition, we briefly describe the results of a recent experiment conducted involving online group discussion concerning the outcome of National Football League games are described. The model predictions concerning the effects of network structure, disagreement level, and team choice (favorite or underdog) are in accord with the experimental results. This research was funded by the Office of Naval Research and the Defense Threat Reduction Agency.

  7. Dynamics of discrete opinions without compromise

    CERN Document Server

    Öztürk, M Kaan

    2011-01-01

    A new agent-based, bounded-confidence model for discrete one-dimensional opinion dynamics is presented. The agents interact if their opinions do not differ more than a tolerance parameter. In pairwise interactions, one of the pair, randomly selected, converts to the opinion of the other. The model can be used to simulate cases where no compromise is possible, such as exclusive choices or competing brands. The fully-mixed case with maximum tolerance is equivalent to the Gambler's Ruin problem. A fully-mixed system always ends up in an absorbing state, which can have one or more surviving opinions. An upper bound for the final number of opinions is given. The distribution of absorption times fits the generalized extreme value distribution. The diffusion coefficient of an opinion increases linearly with the number of opinions within the tolerance parameter. A general master equation and specific Markov matrices are given. The software code developed for this study is provided as a supplement.

Some opinion leaders could be part of the brand community. Thus, companies can enhance positive word of mouth toward the brand by identifying these opinion leaders. However, the company needs to know whether the opinion leader is loyal to the brand in order to avoid negative word of mouth. Twitter offers information about community members that can be useful to identify these opinion leaders. This study analyzes both, the answers to an online questionnaire and the Twitter profile of 265 followers of three camera brands on Twitter. The results show that analyzing the information written by members in their Twitter profile, how many followers they have and how many people or brands they follow is key to identify loyal opinion leaders in brand communities developed in Twitter. Loyal opinion leaders have many followers; however, they do not follow many accounts in this social network site.

    2011-01-01

    The study of opinions, their formation and change, is one of the defining topics addressed by social psychology, but in recent years other disciplines, as computer science and complexity, have addressed this challenge. Despite the flourishing of different models and theories in both fields, several key questions still remain unanswered. The aim of this paper is to challenge the current theories on opinion by putting forward a cognitively grounded model where opinions are described as specific mental representations whose main properties are put forward. A comparison with reputation will be also presented.

    Study Design Retrospective cohort study. Objective To identify predictive factors for blood transfusion and associated complications in lumbar and thoracic fusion surgeries. Methods The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was used to identify patients who underwent lumbar or thoracic fusion from 2010 to 2013. Multivariate analysis was used to determine predictive factors and postoperative complications associated with transfusion. Results Out of 13,695 patients, 13,170 had lumbar fusion and 525 had thoracic fusion. The prevalence of transfusion was 31.8% for thoracic and 17.0% for lumbar fusion. The multivariate analysis showed that age between 50 and 60, age between 61 and 70, age > 70, dyspnea, American Society of Anesthesiologists class 3, bleeding disease, multilevel surgery, extended surgical time, return to operation room, and higher preoperative blood urea nitrogen (BUN) were predictors of blood transfusion for lumbar fusion. Multilevel surgery, preoperative BUN, and extended surgical time were predictors of transfusion for thoracic fusion. Patients receiving transfusions who underwent lumbar fusion were more likely to develop wound infection, venous thromboembolism, pulmonary embolism, and myocardial infarction and had longer hospital stay. Patients receiving transfusions who underwent thoracic fusion were more likely to have extended hospital stay. Conclusion This study characterizes incidence, predictors, and postoperative complications associated with blood transfusion in thoracic and lumbar fusion. Pre- and postoperative planning for patients deemed to be at high risk of requiring blood transfusion might reduce postoperative complications in this population.

    2015-09-01

    Minimally invasive surgery for nephroureterectomy (MINU) in patients with upper tract urothelial carcinoma (UTUC) is increasingly used among urologists with reported equivalent oncologic outcomes compared with open nephroureterectomy (ONU). Population-level data comparing perioperative outcomes between these approaches remain limited, however. We sought to compare perioperative outcomes between MINU and ONU in a prospectively collected national cohort of patients. Between 2006 and 2012, patients who underwent nephroureterectomy for UTUC within the American College of Surgeons-National Surgical Quality Improvement Program database were categorized into MINU or ONU. Our primary outcome of interest was 30-day perioperative complications. Secondary outcomes included use of lymph node dissection (LND), transfusion, reintervention and readmission rate, operative time, length of stay (LOS), and perioperative mortality. Multivariable logistic regression analyses were used to examine the association between outcomes and surgical approach. A total of 599 (66.9%) and 297 (33.1%) patients underwent MINU and ONU, respectively. Overall, 12.7% of patients experienced a complication within 30 days postoperatively, and the rate did not differ among surgical approaches. Patients in the MINU group, however, had a decreased LOS (PONU. MINU, however, was associated with a decreased risk of blood transfusions, thromboembolic events, reintervention, and overall LOS compared with ONU. MINU should be considered as a primary approach in select groups of patients with UTUC.

  16. Social opinion dynamics is not chaotic

    Lim, Chjan; Zhang, Weituo

    2016-08-01

    Motivated by the research on social opinion dynamics over large and dense networks, a general framework for verifying the monotonicity property of multi-agent dynamics is introduced. This allows a derivation of sociologically meaningful sufficient conditions for monotonicity that are tailor-made for social opinion dynamics, which typically have high nonlinearity. A direct consequence of monotonicity is that social opinion dynamics is nonchaotic. A key part of this framework is the definition of a partial order relation that is suitable for a large class of social opinion dynamics such as the generalized naming games. Comparisons are made to previous techniques to verify monotonicity. Using the results obtained, we extend many of the consequences of monotonicity to this class of social dynamics, including several corollaries on their asymptotic behavior, such as global convergence to consensus and tipping points of a minority fraction of zealots or leaders.

    Full Text Available Firms should manage their customer feedback so they can adapt to rapid changes in the environment. They have to interact with their customers to understand them and to turn their opinions into useful knowledge. Understanding customers' feelings about a product gives firmS competitive advantage through continuous market monitoring. They can thus generate improving strategies about the system to change perceptions that drive the behaviours of the customers. Firms can view their customers' happiness as a key tool for decision-making. This study calculates online product happiness by using the average emotional valence values of customer opinions. We analyse Turkish opinions about a product over a period of 3 months. We find the averages of the online emotional valence values of the product per month. We also determined the increase in happiness over time. According to the opinion valence values, we found the relations between the documents.

    Keloglu-Isler, Esra; Erdogan, Irfan

    Cigarette smoking among college students is a critical public health problem with serious personal and social consequences. This study examined college student opinions about smoking in the student cafeteria, hallways and offices, considering smoking as freedom of choice, complying with the cigarette law and policy of universities on smoking. A sample of 1527 students (53.9% female, 46.1% male) attending to the six prestigious universities in Ankara, Turkey, completed a ten-item questionnaire. Results of the study showed that nonsmoking students reported the most favorable opinions toward the issues questioned, whereas occasional smokers and regular smokers reported the least favorable opinions. The highest level of disagreement by smokers and nonsmokers was provided for banning cigarette smoking in the cafeteria. Students generally agreed on that teachers should not smoke in the classrooms and in their offices with doors open. Recommended actions include campus-wide no-smoking policies embracing indoors and outdoors and identification and use of new ways of providing smoking prevention and cessation programs and services.

    2014-02-01

    Non-surgical endodontic retreatment is the treatment of choice for endodontically treated teeth with recurrent or residual disease in the majority of cases. In some cases, surgical endodontic treatment is indicated. Successful micro-surgical endodontic treatment depends on the accuracy of diagnosis, appropriate case selection, the quality of the surgical skills, and the application of the most appropriate haemostatic agents and biomaterials. This article describes the armamentarium and technical procedures involved in performing micro-surgical endodontics to a high standard.

  2. Surgical innovation as sui generis surgical research.

    Lotz, Mianna

    2013-12-01

    Successful innovative 'leaps' in surgical technique have the potential to contribute exponentially to surgical advancement, and thereby to improved health outcomes for patients. Such innovative leaps often occur relatively spontaneously, without substantial forethought, planning, or preparation. This feature of surgical innovation raises special challenges for ensuring sufficient evaluation and regulatory oversight of new interventions that have not been the subject of controlled investigatory exploration and review. It is this feature in particular that makes early-stage surgical innovation especially resistant to classification as 'research', with all of the attendant methodological and ethical obligations--of planning, regulation, monitoring, reporting, and publication--associated with such a classification. This paper proposes conceptual and ethical grounds for a restricted definition according to which innovation in surgical technique is classified as a form of sui generis surgical 'research', where the explicit goal of adopting such a definition is to bring about needed improvements in knowledge transfer and thereby benefit current and future patients.

  3. Discrete Opinion Dynamics on Online Social Networks

    HU Yan-Li; BAI Liang; ZHANG Wei-Ming

    2013-01-01

    This paper focuses on the dynamics of binary opinions {+1,-1} on online social networks consisting of heterogeneous actors.In our model,actors update their opinions under the interplay of social influence and selfaffirmation,which leads to rich dynamical behaviors on online social networks.We find that the opinion leading to the consensus features an advantage of the initially weighted fraction based on actors' strength over the other,instead of the population.For the role of specific actors,the consensus converges towards the opinion that a small fraction of high-strength actors hold,and individual diversity of self-affirmation slows down the ordering process of consensus.These indicate that high-strength actors play an essential role in opinion formation with strong social influence as well as high persistence.Further investigations show that the initial fraction of high-strength actors to dominate the evolution depends on the heterogeneity of the strength distribution,and less high-strength actors are needed in the case of a smaller exponent of power-law distribution of actors' strength.Our study provides deep insights into the role of social influence and self-affirmation on opinion formation on online social networks.

  4. A dynamical model for competing opinions

    CERN Document Server

    Souza, S R

    2012-01-01

    We propose an opinion model based on agents located at the vertices of a regular lattice. Each agent has an independent opinion (among an arbitrary, but fixed, number of choices) and its own degree of conviction. The latter changes every time it interacts with another agent who has a different opinion. The dynamics leads to size distributions of clusters (made up of agents which have the same opinion and are located at contiguous spatial positions) which follow a power law, as long as the range of the interaction between the agents is not too short, i.e. the system self-organizes into a critical state. Short range interactions lead to an exponential cut off in the size distribution and to spatial correlations which cause agents which have the same opinion to be closely grouped. When the diversity of opinions is restricted to two, non-consensus dynamic is observed, with unequal population fractions, whereas consensus is reached if the agents are also allowed to interact with those which are located far from th...

    Following a request from the European Commission, the EFSA Panel on Dietetic Products, Nutrition and Allergies (NDA was asked to carry out the additional assessment for ‘lactoferrin’ as a food ingredient in the context of Regulation (EC No 258/97 taking into account the comments and objections of a scientific nature raised by Member States. Bovine lactoferrin (bLF is a protein that occurs naturally in cow’s milk. The applicant intends to market bLF that is isolated from cheese whey and skimmed milk, and purified. The applicant intends to add bLF to foods for particular nutritional uses, i.e. infant and follow-on formulae, dietary food for special medical purposes, dairy products, yoghurts and yoghurt drinks, and chewing gums. According to the applicant, the high intake estimate for infants would be 1.1 g bLF per day. For adults, the applicant’s calculation estimates a mean and 97.5th percentile intake of 0.6 and 2.1 mg/kg bodyweight per day, respectively, and a mean and 97.5th percentile daily intake of about 45 mg and 150 mg, respectively. The Panel notes that the safety of bLF as a novel food ingredient has already been assessed with a favourable outcome. That evaluation was to a significant extent based on safety data on bLF produced by Morinaga. The Panel also notes that the applicant intends maximum use levels of bLF in foods which are equivalent or lower than those intended by the applicant of the previous Opinion, and that the range of foods to which it is intended to add bLF is smaller. Consequently, the estimated intake levels described for the present application are comparable for infants and lower for all other population groups. The Panel concludes that the novel food ingredient, bLF, is safe under the proposed uses and use levels.

    Surgical education in Mexico basically follows the same model as in the United States, with a selection process resembling the matching program. There is a 4-year training period during which residents in their third year spend 4 months as the sole surgeon in a rural community. During the senior year they are entitled to an elective period in a place of their choosing. After completion of the 4 years, residents have to present a thesis and undergo an oral examination before getting a university diploma. They are then encouraged to pass the written and oral examination of the Mexican Board of Surgery before they are fully certified to enter practice in a public or private hospital.

  8. Can we measure surgical resilience?

    Science.gov (United States)

    Graham, David; Becerril-Martinez, Guillermo; Quinto, Lena; Zhao, Dong Fang

    2016-01-01

    Surgical resilience describes psychological resilience within a surgical setting. Within a surgical setting, psychologically resilient patients have improved recovery and wound-healing. The search for biological correlates in resilient patients has led to the hypothesis that certain endogenous biomarkers (namely neuropeptide Y (NPY), testosterone, and dehydroepiandrosterone (DHEA)) are altered in resilient patients. The concept of surgical resilience raises the question of whether enhanced recovery following surgery can be demonstrated in patients with high titres of resilience biomarkers as compared to patients with low titres of resilience biomarkers. To determine the prognostic value of resilience biomarkers in surgical recovery, a cohort of patients undergoing major surgery should initially be psychometrically tested for their resilience levels before and after surgery so that biomarker levels of NPY, testosterone and DHEA can be compared to a validated psychometric test of resilience. The primary outcome would be length of hospital stay with and without an enhanced recovery program. Secondary outcome measures such as complications, time in rehabilitation and readmission could also be included. If the hypothesis is upheld, resilience biomarkers could be used to support more individualised perioperative management and lead to more efficient and effective allocation of healthcare resources.

  10. Practical problems in aggregating expert opinions

    Energy Technology Data Exchange (ETDEWEB)

    Booker, J.M.; Picard, R.R.; Meyer, M.A.

    1993-11-01

    Expert opinion is data given by a qualified person in response to a technical question. In these analyses, expert opinion provides information where other data are either sparse or non-existent. Improvements in forecasting result from the advantageous addition of expert opinion to observed data in many areas, such as meteorology and econometrics. More generally, analyses of large, complex systems often involve experts on various components of the system supplying input to a decision process; applications include such wide-ranging areas as nuclear reactor safety, management science, and seismology. For large or complex applications, no single expert may be knowledgeable enough about the entire application. In other problems, decision makers may find it comforting that a consensus or aggregation of opinions is usually better than a single opinion. Many risk and reliability studies require a single estimate for modeling, analysis, reporting, and decision making purposes. For problems with large uncertainties, the strategy of combining as diverse a set of experts as possible hedges against underestimation of that uncertainty. Decision makers are frequently faced with the task of selecting the experts and combining their opinions. However, the aggregation is often the responsibility of an analyst. Whether the decision maker or the analyst does the aggregation, the input for it, such as providing weights for experts or estimating other parameters, is imperfect owing to a lack of omniscience. Aggregation methods for expert opinions have existed for over thirty years; yet many of the difficulties with their use remain unresolved. The bulk of these problem areas are summarized in the sections that follow: sensitivities of results to assumptions, weights for experts, correlation of experts, and handling uncertainties. The purpose of this paper is to discuss the sources of these problems and describe their effects on aggregation.

    Consumers increasingly rate, review and research products online. Consequently, websites containing consumer reviews are becoming targets of opinion spam. While recent work has focused primarily on manually identifiable instances of opinion spam, in this work we study deceptive opinion spam---fictitious opinions that have been deliberately written to sound authentic. Integrating work from psychology and computational linguistics, we develop and compare three approaches to detecting deceptive opinion spam, and ultimately develop a classifier that is nearly 90% accurate on our gold-standard opinion spam dataset. Based on feature analysis of our learned models, we additionally make several theoretical contributions, including revealing a relationship between deceptive opinions and imaginative writing.

    Public opinion emergencies have important effect on social activities. Recognition of special communities like opinion leaders can contribute to a comprehensive understanding of the development trend of public opinion. In this paper, a network opinion leader recognition method based on relational data was put forward, and an opinion leader recognition system integrating public opinion data acquisition module, data characteristic selection, and fusion module as well as opinion leader discovery module based on Markov Logic Networks was designed. The designed opinion leader recognition system not only can overcome the incomplete data acquisition and isolated task of traditional methods, but also can recognize opinion leaders comprehensively with considerations to multiple problems by using the relational model. Experimental results demonstrated that, compared with the traditional methods, the proposed method can provide a more accurate opinion leader recognition and has good noise immunity.

    The Authors report on their experience with debulking surgery, based on 46 patients affected by advanced cancers and treated between January 2001 and May 2003 to reduce the tumour mass. Thirty-eight out of 46 (82%) were women. The Authors performed 23 pelvic peritonectomies, 16 multicompartmental peritonectomies according to the Sugarbaker technique, 8 hysterectomies with bilateral ovariectomy, 4 ureteral resections with end-to-end reconstruction, 4 pelvic lymphectomies and 2 resections of the bladder. No perioperative mortality is reported, and major morbidity amounted to less than 5%. The Authors stress the problems encountered while performing debulking surgery and are of the opinion that the majority of the problems could be overcome by precise organization in dedicated surgical centres specifically or mainly devoted to surgical debulking.

    The process of heat conduction (HC) has recently found application in the information filtering [Zhang et al., Phys. Rev. Lett.99, 154301 (2007)], which is of high diversity but low accuracy. The classical HC model predicts users' potential interested objects based on their interesting objects regardless to the negative opinions. In terms of the users' rating scores, we present an improved user-based HC (UHC) information model by taking into account users' positive and negative opinions. Firstly, the objects rated by users are divided into positive and negative categories, then the predicted interesting and dislike object lists are generated by the UHC model. Finally, the recommendation lists are constructed by filtering out the dislike objects from the interesting lists. By implementing the new model based on nine similarity measures, the experimental results for MovieLens and Netflix datasets show that the new model considering negative opinions could greatly enhance the accuracy, measured by the average ranking score, from 0.049 to 0.036 for Netflix and from 0.1025 to 0.0570 for Movielens dataset, reduced by 26.53% and 44.39%, respectively. Since users prefer to give positive ratings rather than negative ones, the negative opinions contain much more information than the positive ones, the negative opinions, therefore, are very important for understanding users' online collective behaviors and improving the performance of HC model.

    2014-01-01

    Although forms of address are widely used in textual and other types of disclosure,empirical evidence of their effects is rare.China provides a unique setting in which to test the economic consequences of the forms of address used in audit reports.From 2003 to 2011,about 60%of auditors surveyed addressed their clients by their real names in audit opinions,while the others used honorifics.Based on a sample of Chinese audit opinions,I report the following findings.First,the announcement of an audit opinion that uses the client’s real name elicits a greater market response than the announcement of an opinion featuring an honorific form of address.Second,the effects of real-name forms of address are stronger in firms with weak board governance.Third,the association between audit fees and audit risk factors,such as loss-making,is stronger in firms that are addressed by their real names in audit reports.I conclude from these findings that the forms of address used in audit opinions may reveal private information on audit quality.The results of this study are consistent with the power-solidarity effect described by sociolinguists.

  16. How opinion dynamics generates group hierarchies

    CERN Document Server

    Gargiulo, F

    2010-01-01

    We recently proposed a model coupling the evolution of the opinions of the individual with the local network topology. The opinion dynamics is based on the Bounded Confidence model. The social networks is based on a group concept where each individual is totally connected to the members of its group and is linked to the individuals of the other groups with a given probability. During a time step, the individual has to decide between discussing with a member of its own network and applying the opinion dynamics, or moving groups because it has an opinion far from the average opinion of its own group. One of the main results we obtained is that the group sizes, starting from an homogeneous situation can be strongly heterogeneous at the equilibrium state. This kind of heterogeneity can be identified in many real networks. In this paper we present the complete set of behaviours that this complex model can exhibit, at group level. In particular we will focus on the mechanisms that lead to the stability of the group...

    As efforts to reduce the overpopulation and euthanasia of unwanted and unowned dogs and cats have increased, greater attention has been focused on spay-neuter programs throughout the United States. Because of the wide range of geographic and demographic needs, a wide variety of programs have been developed to increase delivery of spay-neuter services to targeted populations of animals, including stationary and mobile clinics, MASH-style operations, shelter services, feral cat programs, and services provided through private practitioners. In an effort to ensure a consistent level of care, the Association of Shelter Veterinarians convened a task force of veterinarians to develop veterinary medical care guidelines for spay-neuter programs. The guidelines consist of recommendations for preoperative care (eg, patient transport and housing, patient selection, client communication, record keeping, and medical considerations), anesthetic management (eg, equipment, monitoring, perioperative considerations, anesthetic protocols, and emergency preparedness), surgical care (eg, operating-area environment; surgical-pack preparation; patient preparation; surgeon preparation; surgical procedures for pediatric, juvenile, and adult patients; and identification of neutered animals), and postoperative care (eg, analgesia, recovery, and release). These guidelines are based on current principles of anesthesiology, critical care medicine, microbiology, and surgical practice, as determined from published evidence and expert opinion. They represent acceptable practices that are attainable in spay-neuter programs.

    When individuals in social groups communicate with one another and are under the influence of neighbors’ opinions, they typically revise their own opinions to adapt to such peer opinions. The individual threshold of bounded confidence will thus be affected by both a change in individual confidence and by neighbor influence. Individuals thus update their own opinions with new bounded confidence, while their updated opinions also influence their neighbors’ opinions. Based on this reasoned factual assumption, we propose an opinion dynamics model with time-varying bounded confidence. A directed network is formed by the rule of the individual bounded confidence threshold. The threshold of individual bounded confidence involves both confidence variation and the in/out degree of the individual node. When the confidence variation is greater, an individual’s confidence in persisting in his own opinion in interactions is weaker, and the individual is more likely to adopt neighbors’ opinions. In networks, the in/out degree is determined by individual neighbors. Our main research involves the process of opinion evolution and the basic laws of opinion cluster formation. Group opinions converge exponentially to consensus with stable neighbors. An individual opinion evolution is determined by the average neighbor opinion effect strength. We also explore the conditions involved in forming a stable neighbor relationship and the influence of the confidence variation in the convergence of the threshold of bounded confidence. The results show that the influence on opinion evolution is greater with increased confidence variation. PMID:28264038

    workers in subscribing to treatability of childhood autism, while working experience of less than 6 years among the healthcare workers significantly influenced the opinion of the healthcare workers in admitting to believing in the preventability of childhood autism. Conclusion In designing policies and programs to change negative opinions or beliefs of healthcare workers about childhood autism, there is a need for baseline information such as this survey. Changing the negative opinions or beliefs of the healthcare workers about childhood autism should encourage appropriate help-seeking behavior among parents of children with ASD who may be seeking advice or information from the healthcare workers. This would encourage early interventions, which are essential to prognosis of childhood autism.

    Recently, social phenomena have received a lot of attention not only from social scientists, but also from physicists, mathematicians and computer scientists, in the emerging interdisciplinary field of complex system science. Opinion dynamics is one of the processes studied, since opinions are the drivers of human behaviour, and play a crucial role in many global challenges that our complex world and societies are facing: global financial crises, global pandemics, growth of cities, urbanisation and migration patterns, and last but not least important, climate change and environmental sustainability and protection. Opinion formation is a complex process affected by the interplay of different elements, including the individual predisposition, the influence of positive and negative peer interaction (social networks playing a crucial role in this respect), the information each individual is exposed to, and many others. Several models inspired from those in use in physics have been developed to encompass many of t...

    In clinical practice performing any surgical procedure is inconsistent because all surgical procedures carry definitely some degree of risk. Worldwide every year millions of patients go under knife, but many of them are enduring great pain and shelling out thousands and dollars for surgeries they don't really need. This review work was planned with an intention to focus attention towards it with reporting cited evidences of unnecessary surgical operations and discuss ethical issues concern with it. In present review the references search included standard citations Google scholar, MEDLINE and PUBMED. We also used Google search engine for screening various news concern with highlighting this topic in community and online media. For articles we go through more than 60 articles from worldwide and 12 news media views from Google search in last one year. We used following quotes for their search-unnecessary surgeries, second opinion, ethical issues in unnecessary surgeries. Geographical variations were also kept in view. Our intension was highlighting ethical issues concern with unnecessary surgical operations. Henceforth we excluded such work that does not concern with ethical issues. Unnecessary surgery is that which is medically unjustifiable when the risks and costs are more than the likely therapeutic benefits or relief to the patient based on the patient's lifestyle requirements. To avoid or minimize such interventions basic seeding of ethics in curriculum and strict laws will definitely helpful in clinical practice. In conclusion, our aim was to highlight this major issue and underline need of competency based medical bioethics education in Indian scenario.

    2013-01-01

    In the model for continuous opinion dynamics introduced by Hegselmann and Krause, each individual moves to the average opinion of all individuals within an area of confidence. In this work we study the effects of noise in this system. With certain probability, individuals are given the opportunity to change spontaneously their opinion to another one selected randomly inside the opinion space with different rules. If the random jump does not occur, individuals interact through the Hegselmann-Krause's rule. We analyze two cases, one where individuals can carry out opinion random jumps inside the whole opinion space, and other where they are allowed to perform jumps just inside a small interval centered around the current opinion. We found that these opinion random jumps change the model behavior inducing interesting phenomena. Using pattern formation techniques, we obtain approximate analytical results for critical conditions of opinion cluster formation. Finally, we compare the results of this work with the no...

    Access to safe abortion hinges upon the availability of trained abortion providers. The American College of Obstetricians and Gynecologists supports education for students in health care fields as well as clinical training for residents and advanced practice clinicians in abortion care in order to increase the availability of trained abortion providers. The American College of Obstetricians and Gynecologists supports the expansion of abortion education and an increase in the number and types of trained abortion providers in order to ensure women's access to safe abortions. Integrated medical education and universal opt-out training policies help to lessen the stigma of abortion provision and improve access by increasing the number of abortion providers. This Committee Opinion reviews the current status of abortion education, describes initiatives to ensure the availability of appropriate and up-to-date abortion training, and recommends efforts for integrating and improving abortion education in medical schools, residency programs, and advanced practice clinician training programs.

    2016-11-01

    Mucormycosis as a consequence of trauma is a devastating complication; these infections are challenging to control, with a fatality rate approaching 96% in immunocompromised patients. We present a case where a proactive approach was successfully employed to treat mucormycosis following complex polytrauma. Aggressive repeated surgical debridement, in combination with appropriate antifungal therapy, proved successful in this instance. In our opinion, mucormycosis in trauma mandates an aggressive surgical approach. This prevents ascending dissemination of mucormycosis and certainly reduces the risk of patient mortality as a direct result. Anti-fungal therapy should be used secondarily as an adjunct together with surgical debridement, or as an alternative when surgical intervention is not feasible.

  14. Political opinion formation: Initial opinion distribution and individual heterogeneity of tolerance

    Jin, Cheng; Li, Yifu; Jin, Xiaogang

    2017-02-01

    Opinion dynamics on networks have received serious attention for its profound prospects in social behaviours and self-organized systems. However, political opinion formation, as one typical and significant case, remains lacking in discussion. Previous agent-based simulations propose various models that are based on different mechanisms like the coevolution between network topology and status transition. Nonetheless, even under the same network topology and with the same simple mechanism, forming opinions can still be uncertain. In this work, we propose two features, the initial distribution of opinions and the individual heterogeneity of tolerances on opinion changing, in political opinion formation. These two features are imbedded in the network construction phase of a classical model. By comparing multi simple-party systems, along with a detailed analysis on the two-party system, we capture the critical phenomenon of fragmentation, polarization and consensus both in the persistent stable stage and in-process. We further introduce the average ratio of nearest neighbours to characterize the stage of opinion formation. The results show that the initial distribution of opinions leads to different evolution results on similar random networks. In addition, the existence of stubborn nodes plays a special role: only nodes that are extremely stubborn can cause the change of final opinion distribution while in other cases they only delay the time to reach stability. If stubborn nodes are small in number, their effects are confined within a small range. This theoretical work goes deeper on an existing model, it is an early exploration on qualitative and quantitative simulation of party competition.

    2011-06-01

    Visceral artery aneurysm (VAA) is a rare entity but increased use of abdominal imaging has led to an increased prevalence. Rupture is related to a high mortality rate. Open repair, endovascular treatment and laparoscopic techniques have been described as treatment options. In this systematic review we describe the surgical options for treating VAA. A literature search identified articles focussing on the key issues of visceral artery aneurysms and surgical options using the Pubmed and Cochrane databases. Case reports dominate the literature about VAA. Twenty-seven small case series and ten review articles have been published in the last 20 years concerning the surgical options for VAA. The evidence does not exceed level 3. Surgical treatment is dictated by both patient and aneurysm characteristics. Whether VAA should be treated largely depends upon age, gender, presence of hypertension (e.g. in renal aneurysm), aneurysm size and presentation. Aneurysm size and characteristics, anatomical location and presence of collateral circulation dictate the surgical option to be chosen. The mortality and morbidity rates after elective open repair are low. Literature about surgical options for treating VAA remains scarce. Only a few clinical trials have shown the possibilities and results of open surgical repair. In general, there is no consensus on the surgical treatment of VAA and the highest level of evidence is based upon expert opinions.

Despite the important work done on simulators, simulator model development, and simulator assessment methodologies, there is a need for development of integrated simulators in the curriculum. In this paper, we describe the design of our evidence-based preclinical training program for medical students applying for a surgical career at the Centre for Surgical Technologies. Methods: Twenty-two students participated in this training program. During their final months as medical students, they received structured, proficiency-based endoscopy training. The total amount of mentored training was 18 hours and the training was organized into three training blocks. The first block focused on psychomotor training, the second block focused on laparoscopic stitching and suturing, and the third block on laparoscopic dissection techniques and hemostasis. Deliberate practice was allowed and students had to show proficiency before proceeding to the next training block. Students’ psychomotor abilities were tested before the course and after each training block. At the beginning of their careers as surgical registrars, their performance on a laparoscopic suturing task was compared with that of registrars from the previous year who did not have this training course. Student opinions about this course were evaluated using a visual analog scale. Results: All students rated the training course as useful and their psychomotor abilities improved markedly. All students performed deliberate practice, and those who participated in this course scored significantly (P < 0.0001 better on the laparoscopic suturing task than first year

    Schellhas, Helmut F.; Barnes, Alfonso E.

    1982-12-01

    Multipurpose surgical CO2 lasers marketed in the USA have been developed to be applicable to a variety of surgical procedures in many surgical fields. They are all suited for endoscopic surgical procedures and can be fitted to all standard surgical microscopes. They all can adjust the focal length of the laser beam to the different standard focal lengths of the surgical microscope which for instance in laryngoscopy is 400 mm and in colposcopy 300 mm. One laser instrument can even change the spot size in a given focal distance which is very advantageous for some microsurgical procedures (Merrimack Laboratories 820). All multipurpose surgical CO2 laser systems provide a multi-articulated surgical arm for free-hand surgery. The surgical arms are cumbersome to use but they are adapted to the surgeons needs with ingenuity. The practicality of the multi-articulated surgical arms depends mostly on the distance of the handpiece from the surgical console which now is also overbridged by the laser tube in most surgical laser system. The spot size of the beam is variable in most handpieces by interchangeable lenses which modify the focal distance of the beam and the power density. Another common feature in all systems is a coaxial He-Ne pilot light which provides a red spot which unfortunately becomes invisible in a bleeding surgical field. Most surgical laser systems have a spacial mode of TEM 00 which is essential for incisional surgery. The continuous mode of beam delivery is used for incisional surgery and also for most endoscopic procedures.

    This paper is an effort to identify, as comprehensively as possible, public concerns about nuclear power, and to assess, where possible, the relative importance of these concerns as they relate to government regulation of and policy towards nuclear power. It is based on some two dozen in-depth interviews with key communicators representing the nuclear power industry, the environmental community, and government, as well as on the parallel efforts in our research project: (1) review of federal court case law, (2) a selective examination of the Nuclear Regulatory Commission (NRC) administrative process, and (3) the preceding George Mason University research project in this series. The paper synthesizes our findings about public attitudes towards nuclear power as expressed through federal court case law, NRC administrative law, public opinion surveys, and direct personal interviews. In so doing, we describe the public opinion environment in which the nuclear regulatory process must operate. Our premise is that public opinion ultimately underlies the approaches government agencies take towards regulating nuclear power, and that, to the degree that the nuclear power industry's practices are aligned with public opinion, a more favorable regulatory climate is possible.

    We found cesarean section (C-section) surgical site infection (SSI) at our institution was significantly higher than the national benchmark. A retrospective cohort study was conducted under 4 phases from January 2008-December 2014. The hospital infection control (IC) policies and a presurgical checklist were bundled and implemented. The study was conducted with 3,334 cesarean deliveries: phase A (January 1, 2008-January 31,2010): 1,250 patients without intervention (baseline SSI rate), phase B (February 1, 2010-July 31, 2011): 682 patients were intervened with IC policies, phase C (August 1, 2011-December 31, 2012): 591 patients with an SSI reduction bundle, and phase D (January 1, 2013-December 31, 2014): 811 patients were monitored for C-section SSI sustainability. Patients not following strict protocols because of emergency C-section deliveries were excluded. The χ(2) test, Fisher exact test, and standard Z test were used for statistical analyses. C-section SSI rates were 6.2% (77/1,250) in phase A, 3.7% (25/682) in phase B, 1.7% (10/591) in phase C, and 0.1% (1/811) in phase D, respectively. By implementing the IC policies and bundle, the C-section SSI rate was reduced 40.3% (phase B vs phase A), 72.6% (phase C vs phase A), and 98.4% (phase D vs phase A). All statistics were significantly different. We conclude that implementing a C-section SSI reduction bundle was associated with reduced C-section SSI rate down toward zero. A future prospectively randomized controlled trial is warranted. Copyright © 2016 Association for Professionals in Infection Control and Epidemiology, Inc. Published by Elsevier Inc.

A two-level random effects regression model assessed the influence of Organizational Readiness for Change (ORC) and organizational attributes on opinions toward the use of four evidence-based practices (manualized treatments, medication, integrated mental health services, and motivational incentives) and practices with less empirical support (confrontation and noncompliance discharge). The ORC Scales suggested greater support for evidence-based practices in programs where staff perceived more program need for improvement, better Internet access, higher levels of peer influence, more opportunities for professional growth, a stronger sense of organizational mission and more organizational stress. Support for confrontation and noncompliance discharge, in contrast, was strong when staff saw less opportunity for professional growth, weaker peer influence, less Internet access, and perceived less organizational stress. The analysis provides evidence of the ORC’s utility in assessing agency strengths and needs during the implementation of evidence-based practices. PMID:17434708

    Full Text Available Nurses play a functional role in preventing drug related problems. They need to be aware of the dangers of polypharmacy while reviewing patient medications. We studied the nurses' opinion on the diverse effects of polypharmacy in the hospital setting. Nurses working in a tertiary care teaching hospital participated in this cross-sectional study, conducted over 3 months, by responding to a self-administered questionnaire. Chi-square test was used to analyze association between socio-demographic characteristics and items in the study. A value of P<0.05 was considered statistically significant. Increased drug interactions scored the highest (98.1%, followed by increased adverse drug effects (81.9%, and increase in financial burden (69.5% among the negative effects of polypharmacy. 61% of the respondents felt that polypharmacy increased therapeutic effect in polypathology. No difference was observed in the opinion between male and female nurses or among varying nursing experience. Nurses with 5-10 years of experience opined increase in non-compliance to prescribed medication regimen and increase in financial burden also as negative attributes. Nurses pointed out both positive and negative implications of polypharmacy. Training programs such as continuing nursing education and workshops can be planned to translate this knowledge into practice in their routine nursing practice.

    Full Text Available Abstract Background Continuing Education (CE for chiropractors is mandatory for licensure in most North American jurisdictions. Numerous chiropractic colleges have begun collaborating with universities to offer master's degree programs. Distance education master's degree programs may be desirable to allow full-time practicing doctors to further their post-graduate education. The present survey sought to answer three questions. First, what is the level of satisfaction of chiropractors with their continuing education? Second, what is the level of interest of chiropractors in online master's degree programs? Lastly, what is the response rate of chiropractors to an online survey? Methods An online survey consisting of 22 multiple choice questions was e-mailed to 1000 chiropractors randomly selected from the mailing list of an online chiropractic newsletter. Upon completion of the questionnaire, participants' answers were saved on a secure site. Data analysis included evaluation of the demographic characteristics of the respondents, their opinions of and patterns of taking CE including online education, preferred learning formats, and their interest in proposed online master's degree programs. A survey response rate was determined. Results Nearly 86% of respondents felt their previously completed CE courses were either somewhat or extremely satisfactory. Over ninety percent of respondents who had completed online or distance CE coursesfound them to be somewhat or extremelysatisfactory. Almost half the respondents indicated that they most preferred online distance learning, while 34.08% most preferred face-to-face interaction. Fifty-three percent of respondents indicated an interest in starting a master's degree program; however 70.46% of respondents were interested in an online master's degree program that would offer CE credit. A response rate of 35.8% was obtained. Conclusion Satisfaction among chiropractors with CE programs is high. The notion of

    Various nonpharmacological strategies to relieve hospitalized children's pain propose play as a central element. Play is considered an essential resource to improve the negative psychosocial effects of the disease and the hospitalization itself. However, the empirical research of play in health settings has not received much attention. The goal of this study was to determine the effect of a program to promote play in the hospital on postsurgical pain in pediatric patients. The research hypothesis was that children will manifest less pain if they are distracted through play during the postsurgical period. We carried out a randomized parallel trial with two groups, an experimental group and a control group. The control group did not receive any specific treatment, only the standard attention contemplated in the hospital. The parents of the children from the experimental group received instructions to play with their children in the postsurgical period and specific play material with which to play. The results obtained support the research hypothesis. On average, the children from the experimental group scored lower on a pain scale than the children from the control group. This occurred in the three postsurgical measurements of pain. It is concluded that the program to promote play can decrease children's perception of pain.

    We survey some recent developments on the mathematical modeling of opinion dynamics. After an introduction on opinion modeling through interacting multi-agent systems described by partial differential equations of kinetic type, we focus our attention on two major advancements: optimal control of opinion formation and influence of additional social aspects, like conviction and number of connections in social networks, which modify the agents' role in the opinion exchange process.

  3. Chaotic Modes in Scale Free Opinion Networks

    In this paper, we investigate processes associated with formation of public opinion in varies directed random, scale free and small-world social networks. The important factor of the opinion formation is the existence of contrarians which were discovered by Granovetter in various social psychology experiments1,2,3 long ago and later introduced in sociophysics by Galam.4 When the density of contrarians increases the system behavior drastically changes at some critical value. At high density of contrarians the system can never arrive to a consensus state and periodically oscillates with different periods depending on specific structure of the network. At small density of the contrarians the behavior is manifold. It depends primary on the initial state of the system. If initially the majority of the population agrees with each other a state of stable majority may be easily reached. However when originally the population is divided in nearly equal parts consensus can never be reached. We model the emergence of collective decision making by considering N interacting agents, whose opinions are described by two state Ising spin variable associated with YES and NO. We show that the dynamical behaviors are very sensitive not only to the density of the contrarians but also to the network topology. We find that a phase of social chaos may arise in various dynamical processes of opinion formation in many realistic models. We compare the prediction of the theory with data describing the dynamics of the average opinion of the USA population collected on a day-by-day basis by varies media sources during the last six month before the final Obama-McCain election. The qualitative ouctome is in reasonable agreement with the prediction of our theory. In fact, the analyses of these data made within the paradigm of our theory indicates that even in this campaign there were chaotic elements where the public opinion migrated in an unpredictable chaotic way. The existence of such a phase

    2012-01-01

    We focus on non-consensus opinion models in which above a certain threshold two opinions coexist in a stable relationship. We revisit and extend the non-consensus opinion (NCO) model introduced by Shao. We generalize the NCO model by adding a weight factor W to individual's own opinion when determining its future opinion (NCOW model). We find that as W increases the minority opinion holders tend to form stable clusters with a smaller initial minority fraction compared to the NCO model. We also revisit another non-consensus opinion, the inflexible contrarian opinion (ICO) model, which introduces inflexible contrarians to model a competition between two opinions in the steady state. In the ICO model, the inflexible contrarians effectively decrease the size of the largest cluster of the rival opinion. All of the above models have previously been explored in terms of a single network. However opinions propagate not only within single networks but also between networks, we study here the opinion dynamics in couple...

    2016-01-01

    Background There exists a lack of comparison between large national healthcare databases reporting surgical morbidity and mortality. Prior authors have expressed concern that the Scoliosis Research Society (SRS) membership may have underreported complications in spinal surgery. Thus, the purpose of the present study was to compare the incidence of morbidity between the SRS and National Surgical Quality Improvement Program (NSQIP) databases. Methods We reviewed patients enrolled between 2012 and 2013, with a total of 96,875 patients identified in the SRS dataset and 15,909 in the combined adult and pediatric NSQIP dataset. Patients were matched based on diagnostic category,and a univariate analysis was used to compare reported complication rates in the categories of perioperative infection, neurologic injury, and mortality. The SRS database only requires detailed demographic data reporting on patients that have had a complication event. We compared the demographics and comorbidities of this subgroup, and used this as a surrogate to assess the potential magnitude of confounders. Results Small differences existed between the SRS and NSQIP databases in terms of mortality (0.1% v. 0.2%), infection (1.2% v. 2%), and neurologic injury (0.8% v. 0.1%) (p<0.001 for each comparison). Infection rates were consistently lower across multiple diagnostic sub-categories in the SRS database, whereas neurologic injury rates were consistently lower in the NSQIP database. These differences reached statistical significance across several diagnostic subcategories, but the clinical magnitude of the differences was small. Amongst the patients with a complication, modest differences in comorbidities existed between the two cohorts. Conclusion Overall, the incidence of short-term morbidity and mortality was similar between the two databases. There were modest differences in comorbidities, which may explain the small differences observed in morbidity. Concerns regarding possible under

    Pinotti, Roberto

    During the last three decades the general public's initial opinions about ETI and SETI changed, turning ignorance, fear and superficiality into a gradual understanding of the importance of these concepts. After a brief analysis of this changing psycho-sociological attitude, the paper provides an "estimate of the situation" about general interest for ETI and SETI, suggesting a growing awareness in today's public opinion. Science fiction movies like Close Encounters of the Third Kind and E.T. the Extra-Terrestrial and popular interest in UFOs as visitors from outer space played a major role in the average man's acceptance of the reality of extra-terrestrial life and its meaning for mankind.

    2014-01-01

    We investigate the emergence of extreme opinion trends in society by employing statistical physics modeling and analysis on polls that inquire about a wide range of issues such as religion, economics, politics, abortion, extramarital sex, books, movies, and electoral vote. The surveys lay out a clear indicator of the rise of extreme views. The precursor is a nonlinear relation between the fraction of individuals holding a certain extreme view and the fraction of individuals that includes also moderates, e.g., in politics, those who are "very conservative" versus "moderate to very conservative" ones. We propose an activation model of opinion dynamics with interaction rules based on the existence of individual "stubbornness" that mimics empirical observations. According to our modeling, the onset of nonlinearity can be associated to an abrupt bootstrap-percolation transition with cascades of extreme views through society. Therefore, it represents an early-warning signal to forecast the transition from moderate ...

Considering the upwards trend and the increasing number of online restrictions in Turkey,the opinions of university students (n=138 are thought to give significant findings. The questionnaire aimed to collect dataon some chosen aspects of censorship which are internet access regulation by legal authorities, online pornographiccontent, websites distributing illegal and crime related information and the political and religious aspects of the internetcensorship. The findings about these four basic aspects toward the online censorship revealed that despite the highproportion of approval, participants have a confused and inconsistent attitude towards the issue especially within theapplication and the idea of censorship. In a broader aspect, the findings can be interpreted as a sign of university students’insufficient knowledge and understanding towards the current situation and the possible future of online censorship inTurkey

    Surgical ethics as a specific discipline is relatively new to many. Surgical ethics focuses on the ethical issues that are particularly important to the care of surgical patients. Informed consent for surgical procedures, the level of responsibility that surgeons feel for their patients' outcomes, and the management of surgical innovation are specific issues that are important in surgical ethics and are different from other areas of medicine. The future of surgical progress is dependent on surgical innovation, yet the nature of surgical innovation raises specific concerns that challenge the professionalism of surgeons. These concerns will be considered in the following pages.

    This article describes a new implant placement surgical guide that gives both implant location and trajectory to the surgeon. Radiopaque markers are placed on diagnostic dentures and a lateral cephalometric radiograph is made that shows the osseous anatomy at the symphysis and the anterior tooth location. The ideal implant location and trajectory data are transferred to a surgical stent that programs the angle and location of the fixtures at time of surgery. The stent has the additional benefit of acting as an occlusion rim, a mouth prop, and tongue retractor. Use of this stent has resulted in consistently programming the placement of implant fixtures that are prosthodontically ideal.

    This paper presents a framework to analyze the controllability of opinion dynamics in social networks using DeGroot model (DeGroot, 1974). We show how the opinion, or attitude about some common questions of interest in a population can be controlled by a committed node who consistently proselytizes the opposing opinion and is immune to influence. Some criteria are established to guarantee that opinion dynamics of networks can be perfectly or partially controlled. We also find that the opinion fluctuation is determined by the smallest negative eigenvalue of an influence matrix.

    Many studies have demonstrated the efficacy and the medical/economic value of epidural spinal cord stimulation for the treatment of "failed back surgery syndrome" (FBSS). However, the back pain component of FBSS has been recalcitrant. Recent clinical trials have suggested that multicolumn surgically implanted leads combined with enhanced programming capabilities in the newer implantable pulse generators demonstrate the ability to treat the back pain component of FBSS. The objective of our present international multicentre study is to prospectively evaluate these findings in a larger population. We conducted a prospective, nonrandomized, observational study on 76 patients with refractory FBSS, consecutively implanted with multicolumn spinal cord stimulation (SCS) between 2008 and 2011 in three neurosurgical pain management centers (Poitiers, France; Montréal, Canada; and Regina, Canada). The primary objective of this study was to prospectively analyze the effect of multicolumn lead programming on paresthesia coverage for the back pain region in these patients. The secondary objective was to assess the analgesic efficacy of this technique on the global and back pain components. Paresthesia could be induced in the lower extremities in the majority of patients with at least one of the configurations tested. Bilateral low back paresthesia was induced in 53.5% of patients, while unilateral low back paresthesia was induced in 78.9% of patients. Multicolumn configurations were statistically more effective than monocolumn configurations for all anatomic regions studied. At 6 months, 75.4% of patients receiving multicolumn stimulation (n = 57) obtained at least a 30% improvement of the back pain VAS score, while 42.1% of patients obtained at least a 50% improvement of the back pain VAS score. This study confirms the hypothesis that multicolumn SCS should be considered as an important tool in the treatment of radicular and axial pain in FBSS patients. The efficacy of this

    Full Text Available The success of an epilepsy surgery program depends upon the early identification of potential surgical candidates and selecting from them, ideal candidates for surgery, who are destined to have a post-operative seizure-free outcome without any unacceptable neurological deficits. Since epilepsy surgery centers in resource-poor countries will lack the full range of state-of-the-art technologies usually available in resource-rich countries to perform pre-surgical evaluation, cost-effectively utilization of the locally available investigative facilities to select the surgical candidates becomes challenging. In the present era of rapid electronic communications and telemedicine, it has become possible for epilepsy surgery centers to pool their technological and human resources and to partner with centers nationally and internationally in implementing pre-surgical evaluation strategies.

    The rapid development of Web technology has resulted in an increasing number of hotel customers sharing their opinions on the hotel services. Effective visual analysis of online customer opinions is needed, as it has a significant impact on building a successful business. In this paper, we present OpinionSeer, an interactive visualization system that could visually analyze a large collection of online hotel customer reviews. The system is built on a new visualization-centric opinion mining technique that considers uncertainty for faithfully modeling and analyzing customer opinions. A new visual representation is developed to convey customer opinions by augmenting well-established scatterplots and radial visualization. To provide multiple-level exploration, we introduce subjective logic to handle and organize subjective opinions with degrees of uncertainty. Several case studies illustrate the effectiveness and usefulness of OpinionSeer on analyzing relationships among multiple data dimensions and comparing opinions of different groups. Aside from data on hotel customer feedback, OpinionSeer could also be applied to visually analyze customer opinions on other products or services.

    Social dynamic opinion models have been widely studied to understand how interactions among individuals cause opinions to evolve. Most opinion models that utilize spin interaction models usually produce a consensus steady state in which only one opinion exists. Because in reality different opinions usually coexist, we focus on non-consensus opinion models in which above a certain threshold two opinions coexist in a stable relationship. We revisit and extend the non-consensus opinion (NCO) model introduced by Shao et al. (Phys. Rev. Lett. 103:01870, 2009). The NCO model in random networks displays a second order phase transition that belongs to regular mean field percolation and is characterized by the appearance (above a certain threshold) of a large spanning cluster of the minority opinion. We generalize the NCO model by adding a weight factor W to each individual's original opinion when determining their future opinion (NCO W model). We find that as W increases the minority opinion holders tend to form stable clusters with a smaller initial minority fraction than in the NCO model. We also revisit another non-consensus opinion model based on the NCO model, the inflexible contrarian opinion (ICO) model (Li et al. in Phys. Rev. E 84:066101, 2011), which introduces inflexible contrarians to model the competition between two opinions in a steady state. Inflexible contrarians are individuals that never change their original opinion but may influence the opinions of others. To place the inflexible contrarians in the ICO model we use two different strategies, random placement and one in which high-degree nodes are targeted. The inflexible contrarians effectively decrease the size of the largest rival-opinion cluster in both strategies, but the effect is more pronounced under the targeted method. All of the above models have previously been explored in terms of a single network, but human communities are usually interconnected, not isolated. Because opinions propagate not

    We propose the PageRank model of opinion formation and investigate its rich properties on real directed networks of the Universities of Cambridge and Oxford, LiveJournal, and Twitter. In this model, the opinion formation of linked electors is weighted with their PageRank probability. Such a probability is used by the Google search engine for ranking of web pages. We find that the society elite, corresponding to the top PageRank nodes, can impose its opinion on a significant fraction of the society. However, for a homogeneous distribution of two opinions, there exists a bistability range of opinions which depends on a conformist parameter characterizing the opinion formation. We find that the LiveJournal and Twitter networks have a stronger tendency to a totalitarian opinion formation than the university networks. We also analyze the Sznajd model generalized for scale-free networks with the weighted PageRank vote of electors.

    We investigate opinion formation in a kinetic exchange opinion model, where opinions are represented by numbers in the real interval $[-1,1]$ and agents are typified by the individual degree of conviction about the opinion that they support. Opinions evolve through pairwise interactions governed by competitive positive and negative couplings, that promote imitation and dissent, respectively. The model contemplates also another type of nonconformity such that agents can occasionally choose their opinions independently of the interactions with other agents. The steady states of the model as a function of the parameters that describe conviction, dissent and independence are analyzed, with particular emphasis on the emergence of extreme opinions. Then, we characterize the possible ordered and disordered phases and the occurrence or suppression of phase transitions that arise spontaneously due to the disorder introduced by the heterogeneity of the agents and/or their interactions.

    Full Text Available This study investigates the effect of auditor-management alignment on audit opinion over the period 2003- 2011 on 81 firms listed on the Tehran Stock Exchange using logistic regression analysis. Results indicate that in companies with auditor-management alignment, auditor change level is low. In addition, the results indicate there is no relationship between auditor-management alignment, debt ratio, ownership percentage, firm size and auditor change with unqualified audit opinion. However, research evidences show that auditor's opinion type at previous year, audit fees, auditor type and return on assets ratio influence unqualified audit opinion. Among above variables, auditor's opinion types at previous year, audit fees and return on assets ratio have direct relationship with unqualified audit opinion but auditor type has a negative and inverse relationship with unqualified audit opinion.

Métodos: Encuesta postal a los pediatras de atención primaria de Castilla y León, explorando la necesidad de acción frente a la obesidad, la utilidad de medidas terapéuticas y estrategias preventivas, las barreras que obstaculizan el tratamiento, las herramientas útiles para el pediatra, la eficacia propia en el tratamiento de la obesidad y la utilidad de incorporar la obesidad a la cartera de servicios. Resultados: Se consideró la obesidad como un problema de salud importante que necesita una actuación por parte de los pediatras. Esta disposición a la acción era menor entre quienes manifestaron más barreras personales. Las barreras más frecuentes procedían del medio social: disponibilidad y publicidad de determinados alimentos y bebidas, dificultades en involucrar a los padres en el tratamiento, ausencia de percepción del problema por el niño y los padres. La herramienta mejor considerada fue la formación del personal sanitario. Los pediatras se consideraban algo o poco eficaces en el tratamiento de la obesidad. La efectividad de un servicio de atención a la obesidad en atención primaria pareció ligeramente superada por la carga de trabajo que requeriría. Conclusiones: Pese a su alta disposición a la acción frente a la obesidad, los pediatras se sienten limitados debido a las barreras que encuentran, sobre todo de tipo social o cultural, y demandan más formación como una herramienta frente a la epidemia de obesidad infantil.Objectives: To identify the Spanish pediatricians' opinions and attitudes towards obesity, in relation with its treatment, prevention, and care organization, barriers they find in its treatment

    This study aims to explore the views of members of theater teams regarding the proposed introduction of a workplace-based assessment of nontechnical skills of surgeons (NOTSS) into the Intercollegiate Surgical Curriculum Programme in the United Kingdom. In addition, the previous training and familiarity of the members of the surgical theater team with the concept and assessment of NOTSS would be evaluated. A regional survey of members of theater teams (consultant surgeons, anesthetists, scrub nurses, and trainees) was performed at 1 teaching and 2 district general hospitals in South Yorkshire. There were 160 respondents corresponding to a response rate of 81%. The majority (77%) were not aware of the NOTSS assessment tool with only 9% of respondents reporting to have previously used the NOTSS tool and just 3% having received training in NOTSS assessment. Overall, 81% stated that assessing NOTSS was as important as assessing technical skills. Trainees attributed less importance to nontechnical skills than the other groups (p ≤ 0.016). Although opinion appears divided as to whether the presence of a consultant surgeon in theater could potentially make it difficult to assess a trainee's leadership skills and decision-making capabilities, overall 60% agree that the routine use of NOTSS assessment would enhance safety in the operating theater and 80% agree that the NOTSS tool should be introduced to assess the nontechnical skills of trainees in theater. However, a significantly lower proportion of trainees (45%) agreed on the latter compared with the other groups (p = 0.001). Our survey demonstrates acceptability among the theater team for the introduction of the NOTSS tool into the surgical curriculum. However, lack of familiarity highlights the importance of faculty training for assessors before such an introduction. Copyright © 2015 Association of Program Directors in Surgery.

    Vercler, Christian J

    2015-01-01

    The encounter between a patient and her surgeon is unique for several reasons. The surgeon inflicts pain upon a patient for the patient's own good. An operative intervention is irreducibly personal, such that the decisions about and performance of operations are inseparable from the idiosyncrasies of the individual surgeon. Furthermore, there is a chasm of knowledge between the patient and surgeon that is difficult to cross. Hence, training in the discipline of surgery includes the inculcation of certain virtues and practices to safeguard against abuses of this relationship and to make sure that the best interests of the patient are prioritized. The stories in this issue are evidence that in contemporary practice this is not quite enough, as surgeons reflect on instances they felt were ethically challenging. Common themes include the difficulty in communicating surgical uncertainty, patient-surgeon relationships, ethical issues in surgical training, and the impact of the technological imperative on caring for dying patients.

    A project was undertaken to improve robotic surgical tools for telerobotic minimally invasive surgery. The major objectives were to reduce the size of the tools to permit new surgical procedures in confined spaces such as the heart and to improve control of surgical tools by locating positional sensors and actuators at the end effector rather than external to the patient as is currently the state of the technology. A new compact end-effector with wrist-like flexibility was designed. Positional sensors based on MEMS microfabrication techniques were designed.

    Surgical education has undergone radical changes in the past decade. The introductions of laparoscopic surgery and endovascular techniques have required program directors to alter surgical training. The 6 competencies are now in place. One issue that still needs to be addressed is the business aspect of surgical practice. Often residents complete their training with minimal or no knowledge on coding of charges or basic aspects on how to set up a practice. We present our program, which has been in place over the past 2 years and is designed to teach the residents practice management. The program begins with a series of 10 lectures given monthly beginning in August. Topics include an introduction to types of practices available, negotiating a contract, managed care, and marketing the practice. Both medical and surgical residents attend these conferences. In addition, the surgical residents meet monthly with the business office to discuss billing and coding issues. These are didactic sessions combined with in-house chart reviews of surgical coding. The third phase of the practice management plan has the coding team along with the program director attend the outpatient clinic to review in real time the evaluation and management coding of clinic visits. Resident evaluations were completed for each of the practice management lectures. The responses were recorded on a Likert scale. The scores ranged from 4.1 to 4.8 (average, 4.3). Highest scores were given to lectures concerning negotiating employee agreements, recruiting contracts, malpractice insurance, and risk management. The medical education department has tracked resident coding compliance over the past 2 years. Surgical coding compliance increased from 36% to 88% over a 12-month period. The program director who participated in the educational process increased his accuracy from 50% to 90% over the same time period. When residents finish their surgical training they need to be ready to enter the world of business

    Full Text Available Social media constitutes a major component of Web 2.0 and includes social networks, blogs, forum discussions, micro-blogs, etc. Users of social media generate a huge volume of reviews and comments on daily basis. These reviews and comments reflect the opinions of users about different issues, such as: products, news, entertainments, or sports. Therefore different establishments may need to analyze these reviews and comments. For examples: It is essential for companies to know the pros and cons of their products or services in the eyes of customers. Governments may want In addition to know the attitude of people towards certain decisions, services, etc. Although the manual analysis of textual reviews and comments can be more accurate than the automatic methods, nonetheless, it is time consuming, expensive, and can be In addition subjective. In addition, the huge amount of data contained in social networks can make it impractical to perform analysis manually. This paper focuses on evaluating social content in Arabic language and contexts. Currently, Middle East is an area rich of major political and social reforms. The social media can be a rich source of information to evaluate such contexts. In this research we developed an opinion mining and analysis tool to collect different forms of Arabic language (i.e. Standard or MSA, and colloquial. The tool accepts comments or opinions as input and generates polarity based outputs related to the comments. For example the output can be whether the comment or review is: (subjective or objective, (positive or negative, and (strong or weak. The evaluation of the performance of the developed tool showed that it yields more accurate results when it is applied on domain-based Arabic reviews relative to general-based Arabic reviews.

The interview form included these questions; (i Which characteristics do you think a conscious consumer has? (ii As a consumer what do you pay attention to when you are shopping? Results i.\tThe result of the research showed that the students have knowledge about the characteristics of a conscious consumer. The students stated that the conscious consumer should have consumer responsibility consciousness, quality consciousness, budget-cost consciousness. ii.\tWhen the opinions of the students, who took part in the research, regarding their own consumer responsibility consciousness, quality consciousness, budget-cost consciousness were analyzed, it was found out that the students have enough knowledge about the subject and regard themselves as conscious consumers. Discussion and Conclusion: The students stated that the conscious consumer should have consumer responsibility consciousness, quality consciousness, budget-cost consciousness. This finding was regarded as significant in the sense that “From Production to Consume” unit in Social Science Programs of primary school 4th grade raises the students’ awareness of conscious consumerism. This result shows parallelism with the study conducted by Sağlam (2010. The researcher in question states in his study of conscious consumerism that the students got high scores from the scale. Besides, in their study Makela and Peters (2004 indicate that consumer education has a positive impact on students’ awareness of consumer rights and responsibilities.

    2014-12-01

    A dynamical model with continuous opinion is proposed to study how the speech order and the topology of directed social network affect the opinion formation of free speech. In the model, agents express their opinions one by one with random order (RO) or probability order (PO), other agents paying attentions to the speaking agent, receive provider's opinion, update their opinions and then express their new opinions in their turns. It is proved that with the same agent j repeats its opinion more, other agents who pay their attentions to j and include j's opinion in their confidence level at initial time, will continue approaching j's opinion. Simulation results reveal that on directed scale-free network: (1) the model for PO forms fewer opinion clusters, larger maximum cluster (MC), smaller standard deviation (SD), and needs less waiting time to reach a middle level of consensus than RO; (2) as the parameter of scale-free degree distribution decreases or the confidence level increases, the results often get better for both speech orders; (3) the differences between PO and RO get smaller as the size of network decreases.

    2017-08-01

    To reveal heterogeneous behaviors of opinion evolution in different scenarios, we propose an opinion model with topic interactions. Individual opinions and topic features are represented by a multidimensional vector. We measure an agent's action towards a specific topic by the product of opinion and topic feature. When pairs of agents interact for a topic, their actions are introduced to opinion updates with bounded confidence. Simulation results show that a transition from a disordered state to a consensus state occurs at a critical point of the tolerance threshold, which depends on the opinion dimension. The critical point increases as the dimension of opinions increases. Multiple topics promote opinion interactions and lead to the formation of macroscopic opinion clusters. In addition, more topics accelerate the evolutionary process and weaken the effect of network topology. We use two sets of large-scale real data to evaluate the model, and the results prove its effectiveness in characterizing a real evolutionary process. Our model achieves high performance in individual action prediction and even outperforms state-of-the-art methods. Meanwhile, our model has much smaller computational complexity. This paper provides a demonstration for possible practical applications of theoretical opinion dynamics.

    We investigate the emergence of extreme opinion trends in society by employing statistical physics modeling and analysis on polls that inquire about a wide range of issues such as religion, economics, politics, abortion, extramarital sex, books, movies, and electoral vote. The surveys lay out a clear indicator of the rise of extreme views. The precursor is a nonlinear relation between the fraction of individuals holding a certain extreme view and the fraction of individuals that includes also moderates, e.g., in politics, those who are “very conservative” versus “moderate to very conservative” ones. We propose an activation model of opinion dynamics with interaction rules based on the existence of individual “stubbornness” that mimics empirical observations. According to our modeling, the onset of nonlinearity can be associated to an abrupt bootstrap-percolation transition with cascades of extreme views through society. Therefore, it represents an early-warning signal to forecast the transition from moderate to extreme views. Moreover, by means of a phase diagram we can classify societies according to the percolative regime they belong to, in terms of critical fractions of extremists and people’s ties.

    Full Text Available Listening skill has an important place in people’s life, but is often neglected. This skill is obtained before birth, and should be developed systematically at school. People with developed listening skill are successful at education and in their social lives. To achieve this skill teachers are very important. First of all teachers should have enough knowledge about listening and listening problems. Especially Turkish teachers should try to improve listening skill. The aim of this study is to show the problems of Turkish teachers about listening and develop opinions and approaches to solve these problems. For this reason 97 Turkish-teacher candidates of Çukurova University were questioned in 2012-2013 academic year and these opinions were investigated according to gender factor. The question “What are the problems you face when listening to someone?” was asked, and so answered according to willingness. Data obtained from participants were investigated with content analyze technique, and classified into categories, sub-categories and themes. Participants indicated that listening problems happen % 58 because of senders, and % 22 because of receivers and % 21 because of other problems. It was observed that there is no great different on the base of gender. Some evaluations were made about listening problems and some suggestions were made.

Here, we show that active network maintenance exposes agents to confirmation bias, the tendency to confirm one's beliefs, and we explore how this affects collective opinion formation. We introduce a model of binary opinion dynamics on a complex network with fast, stochastic rewiring and show that confirmation bias induces a segregation of individuals with different opinions. We use the dynamics of global opinion to generally categorize opinion update rules and find that confirmation bias always stabilizes the consensus state. Finally, we show that the time to reach consensus has a non-monotonic dependence on the magnitude of the bias, suggesting a novel avenue for large-scale opinion engineering.

    Feng, Chen-Jie; Huo, Jie; Hao, Rui; Wang, Xu-Ming

    2016-01-01

    A physical description of an opinion evolution is conducted based on the Hamilton-Jacobi equation derived from a generalized potential and the corresponding Langevin equation. The investigation mainly focuses on the heterogeneities such as age, connection circle and overall quality of the participants involved in the opinion exchange process. The evolutionary patterns of opinion can be described by solution of the Hamilton-Jacobi equation, information entropy. The results show that the overall qualities of the participants play critical roles in forming an opinion. The higher the overall quality is, the easier the consensus can reach. The solution also demonstrates that the age and the connection circle of the agents play equally important roles in forming an opinion. The essence of the age, overall quality, and connection circle corresponds to the maturity of thought (opinion inertia), reason and intelligence, influence strength of the environment, respectively. So the information entropy distributes in the ...

    2012-01-01

    We present the result of a dual modeling of opinion network. The model complements the agent-based opinion models by attaching to the social agent (voters) network a political opinion (party) network having its own intrinsic mechanisms of evolution. These two sub-networks form a global network which can be either isolated from or dependent on the external influence. Basically, the evolution of the agent network includes link adding and deleting, the opinion changes influenced by social validation, the political climate, the attractivity of the parties and the interaction between them. The opinion network is initially composed of numerous nodes representing opinions or parties which are located on a one dimensional axis according to their political positions. The mechanism of evolution includes union, splitting, change of position and of attractivity, taken into account the pairwise node interaction decaying with node distance in power law. The global evolution ends in a stable distribution of the social agent...

    Surgeon-industry conflict of interest (COI) has become a source of considerable interest. Professional medical societies, industry, and policy makers have attempted to regulate potential COI without consideration for public opinion. The objective of this study was to report on the opinions of individuals representing the general public regarding surgeon-industry consulting relationships. Web-based survey. Survey was administered using a "spine Web site," and opinions are collected on surgeon-industry consulting and regulation. Associations among responses to similar questions were assessed to ensure validity and subgroup analysis performed for respondent age, sex, education, insurance, employment, and patient status. Six hundred ten of 642 surveys had complete data. The sample population comprised more females and was older and more educated than the American population. About 80% of respondents felt it was ethical and either beneficial or of no influence to the quality of health care if surgeons were consultants for surgical device companies. Most felt disclosure of an industry relationship was important and paying surgeons royalties for devices, other than those they directly implant, would not affect quality of care. Respondents support multidisciplinary surgeon-industry COI regulation and trust doctors and their professional societies to head this effort. Despite the known potential negative impact of surgeon-industry COI on patient care, this study revealed that this does not seem to be reflected in the opinion of the general public. The respondents felt that disclosure is deemed one of the most important means of self-regulation and COI management, which is in agreement with current trends of most spine societies and journals that are increasing the stringency of disclosure policies.

    Full Text Available In this study, Dewey’s opinions of education have been considered establishing relation with Turkish education. He adapted pragmatist philosophy to fit education. According to him, education is an action keeping on during the life. For this reason, performing and living have obtained the most effective learning. The child’s naturalcharacter and, his individual specialties should be taken into consideration and, the focus of education should bebeen child, also lessons should be prepared according to his interest and abilities. The child should never be forcedfor a passive and without comprehending education. The education program should be prepared for concentrating on practice instead of theory. The knowledge should never be presented the child with a simple way to be able to provide his thinking and discovery.Consequently, Dewey’s opinions suggested important approaches about education and, also they were the initiator of another new opinion. Thinking again his opinions is important because of serving us a chance to be able to evaluate our education system on a critical way.

    2014-10-01

    The aim of this study was to evaluate dental students' opinions regarding the utilization of a new grading software program for student self-assessment and a faculty-grading tool in a preclinical course. Using surface mapping technology, this program, called E4D Compare, yields a digital model of a student's preparation that is color-coded to show deficient areas. The program has now been used for two years at the James B. Edwards College of Dental Medicine at the Medical University of South Carolina, and the students previously assessed with E4D Compare have now entered into the dental clinics. For this study, students were asked to complete an anonymous survey for the investigators to evaluate students' attitudes and opinions on the effectiveness of this software in their preclinical courses to determine if this type of feedback helped them develop clinical skills. The survey also sought to collect students' opinions on the traditional objective criteria-based grading system. The survey was distributed to all members of the Classes of 2014 and 2015; it yielded a 59 percent response rate for the two classes, with a total of eighty-one students responding. Overall, the majority of students preferred the E4D Compare grading system over traditional hand-grading methods. The grading system provided instant, objective, and visual feedback that allowed students to easily see where their deficiencies were and encouraged them to work towards an ideal final product.

    2009-01-01

    Politicians use public opinion polling data if the data are available to them. Most of these data are from national polls and do not allow for state-level analysis. One promising strategy for informing elected state officials about health issues is to administer public opinion polls at the state level. Combined with health assessment surveys, public opinion data provide a powerful tool for health policy development. This Report reviews one regional foundation's efforts at providing public opinion poll data at the state level and the results of these efforts.

    Chakhmakhchyan, L

    2013-01-01

    We consider a PageRank model of opinion formation on Ulam networks, generated by the intermittency map and the typical Chirikov map. The Ulam networks generated by these maps have certain similarities with such scale-free networks as the World Wide Web (WWW), showing an algebraic decay of the PageRank probability. We find that the opinion formation process on Ulam networks have certain similarities but also distinct features comparing to the WWW. We attribute these distinctions to internal differences in network structure of the Ulam and WWW networks. We also analyze the process of opinion formation in the frame of generalized Sznajd model which protects opinion of small communities.

    This paper discusses the development of methods for computer-aided jaw surgery. Computer-aided jaw surgery allows us to incorporate the high level of precision necessary for transferring virtual plans into the operating room. We also present a complete computer-aided surgery (CAS) system developed in close collaboration with surgeons. Surgery planning and simulation include construction of 3D surface models from Cone-beam CT (CBCT), dynamic cephalometry, semi-automatic mirroring, interactive cutting of bone and bony segment repositioning. A virtual setup can be used to manufacture positioning splints for intra-operative guidance. The system provides further intra-operative assistance with the help of a computer display showing jaw positions and 3D positioning guides updated in real-time during the surgical procedure. The CAS system aids in dealing with complex cases with benefits for the patient, with surgical practice, and for orthodontic finishing. Advanced software tools for diagnosis and treatment planning allow preparation of detailed operative plans, osteotomy repositioning, bone reconstructions, surgical resident training and assessing the difficulties of the surgical procedures prior to the surgery. CAS has the potential to make the elaboration of the surgical plan a more flexible process, increase the level of detail and accuracy of the plan, yield higher operative precision and control, and enhance documentation of cases.

    Campbell, M. R.; Billica, R. D.; Johnston, S. L. 3rd

    1993-01-01

    A surgical procedure performed during space flight would occur in a unique microgravity environment. Several experiments performed during weightlessness in parabolic flight were reviewed to ascertain the behavior of surgical bleeding in microgravity. Simulations of bleeding using dyed fluid and citrated bovine blood, as well as actual arterial and venous bleeding in rabbits, were examined. The high surface tension property of blood promotes the formation of large fluid domes, which have a tendency to adhere to the wound. The use of sponges and suction will be adequate to prevent cabin atmosphere contamination with all bleeding, with the exception of temporary arterial droplet streams. The control of the bleeding with standard surgical techniques should not be difficult.

    Full Text Available André AM Torricelli, Jackson B Junior, Marcony R Santhiago, Samir J BecharaDivision of Ophthalmology, University of São Paulo Medical School, São Paulo, BrazilAbstract: Presbyopia, the gradual loss of accommodation that becomes clinically significant during the fifth decade of life, is a physiologic inevitability. Different technologies are being pursued to achieve surgical correction of this disability; however, a number of limitations have prevented widespread acceptance of surgical presbyopia correction, such as optical and visual distortion, induced corneal ectasia, haze, anisometropy with monovision, regression of effect, decline in uncorrected distance vision, and the inherent risks with invasive techniques, limiting the development of an ideal solution. The correction of the presbyopia and the restoration of accommodation are considered the final frontier of refractive surgery. The purpose of this paper is to provide an update about current procedures available for presbyopia correction, their advantages, and disadvantages.Keywords: presbyopia, surgical correction, treatment

    Humans, like many other animal species, often make choices under social influence. Experiments in ants and fishes have shown that individuals choose according to estimations of which option to take given private and social information. Principled approaches based on probabilistic estimations by agents give mathematical formulas explaining experiments in these species. Here we test whether the same principled approaches can explain social influence in humans. We conduct a large online field experiment in which we measure opinion influenced by public comments about short movies in the most popular video-sharing website. We show that the basic principles of social influence in other species also apply to humans, with the added complexity that humans are heterogenous. We infer influenceability of each participant of the experiment, finding that individuals prone to social influence tend to agree with social feedback, read less comments, and are less educated than the persons who resist influence. We believe that ...

    2007-09-01

    This study was conducted to gain opinions about euthanasia from nurses who work in intensive care units. The research was planned as a descriptive study and conducted with 186 nurses who worked in intensive care units in a university hospital, a public hospital, and a private not-for-profit hospital in Adana, Turkey, and who agreed to complete a questionnaire. Euthanasia is not legal in Turkey. One third (33.9%) of the nurses supported the legalization of euthanasia, whereas 39.8% did not. In some specific circumstances, 44.1% of the nurses thought that euthanasia was being practiced in our country. The most significant finding was that these Turkish intensive care unit nurses did not overwhelmingly support the legalization of euthanasia. Those who did support it were inclined to agree with passive rather than active euthanasia (P = 0.011).

    As community efforts to reduce the overpopulation and euthanasia of unwanted and unowned cats and dogs have increased, many veterinarians have increasingly focused their clinical efforts on the provision of spay-neuter services. Because of the wide range of geographic and demographic needs, a wide variety of spay-neuter programs have been developed to increase delivery of services to targeted populations of animals, including stationary and mobile clinics, MASH-style operations, shelter services, community cat programs, and services provided through private practitioners. In an effort to promote consistent, high-quality care across the broad range of these programs, the Association of Shelter Veterinarians convened a task force of veterinarians to develop veterinary medical care guidelines for spay-neuter programs. These guidelines consist of recommendations for general patient care and clinical procedures, preoperative care, anesthetic management, surgical procedures, postoperative care, and operations management. They were based on current principles of anesthesiology, critical care medicine, infection control, and surgical practice, as determined from published evidence and expert opinion. They represent acceptable practices that are attainable in spay-neuter programs regardless of location, facility, or type of program. The Association of Shelter Veterinarians envisions that these guidelines will be used by the profession to maintain consistent veterinary medical care in all settings where spay-neuter services are provided and to promote these services as a means of reducing sheltering and euthanasia of cats and dogs.

    Full Text Available The purpose of the current study is to determine the communication competence of school directors working in various secondary schools in the city of Usak, Turkey, in relation to variables on the basis of teachers’ opinions. The population of the study, which employs the descriptive survey model, is comprised of 820 teachers working in 18 secondary schools located in the city of Usak during the 2014-2015 school year. All the schools included in the study were visited and the questionnaire given to teachers who were willing to participate in the study. Of the distributed questionnaires, only 301 were subjected to analysis. The research data were collected by using “Communication Competence Scale for Elementary School Directors” developed by Topluer (2008. The statistical analyses of the collected data were conducted using the SPSS (Statistical Package for Social Sciences 17.0 program by means of descriptive statistics, t-test, one-way variance analysis (ANOVA and Tukey significance test. Findings revealed that in general the teachers think that the school directors’ communication competence is high. The school directors’ communication competence for the dimensions of understanding, empathy, social comfort, and support was found to be “mostly” positive. Moreover, it was also concluded that the gender variable has no significant effect on teachers’ opinions about any of the sub-dimensions of directors’ communication competence. However, the teachers’ opinions about the sub-dimension of support were found to vary on the age variable. Older teachers are of the opinion that school directors demonstrate more supportive communication patterns. The number of teachers in a school was also found to significantly affect teachers’ opinions. In terms of the sub-dimensions of understanding empathy and social comfort, with increasing numbers of teachers, the school director’s communication competence in general is evaluated more

  6. Influence of opinion dynamics on the evolution of games.

    Directory of Open Access Journals (Sweden)

    Floriana Gargiulo

    Full Text Available Under certain circumstances such as lack of information or bounded rationality, human players can take decisions on which strategy to choose in a game on the basis of simple opinions. These opinions can be modified after each round by observing own or others payoff results but can be also modified after interchanging impressions with other players. In this way, the update of the strategies can become a question that goes beyond simple evolutionary rules based on fitness and become a social issue. In this work, we explore this scenario by coupling a game with an opinion dynamics model. The opinion is represented by a continuous variable that corresponds to the certainty of the agents respect to which strategy is best. The opinions transform into actions by making the selection of an strategy a stochastic event with a probability regulated by the opinion. A certain regard for the previous round payoff is included but the main update rules of the opinion are given by a model inspired in social interchanges. We find that the fixed points of the dynamics of the coupled model are different from those of the evolutionary game or the opinion models alone. Furthermore, new features emerge such as the independence of the fraction of cooperators with respect to the topology of the social interaction network or the presence of a small fraction of extremist players.

    Zhou, Xin; Chen, Bin; Liu, Liang; Ma, Liang; Qiu, Xiaogang

    2015-01-01

    In order to study the formation process of group opinion in real life, we put forward a new opinion interactive model based on Deffuant model and its improved models in this paper because current models of opinion dynamics lack considering individual persuasiveness. Our model has following advantages: firstly persuasiveness is added to individual's attributes reflecting the importance of persuasiveness, which means that all the individuals are different from others; secondly probability is introduced in the course of interaction which simulates the uncertainty of interaction. In Monte Carlo simulation experiments, sensitivity analysis including the influence of randomness, initial persuasiveness distribution, and number of individuals is studied at first; what comes next is that the range of common opinion based on the initial persuasiveness distribution can be predicted. Simulation experiment results show that when the initial values of agents are fixed, no matter how many times independently replicated experiments, the common opinion will converge at a certain point; however the number of iterations will not always be the same; the range of common opinion can be predicted when initial distribution of opinion and persuasiveness are given. As a result, this model can reflect and interpret some phenomena of opinion interaction in realistic society.

  2. Influence of Opinion Dynamics on the Evolution of Games

    Under certain circumstances such as lack of information or bounded rationality, human players can take decisions on which strategy to choose in a game on the basis of simple opinions. These opinions can be modified after each round by observing own or others payoff results but can be also modified after interchanging impressions with other players. In this way, the update of the strategies can become a question that goes beyond simple evolutionary rules based on fitness and become a social issue. In this work, we explore this scenario by coupling a game with an opinion dynamics model. The opinion is represented by a continuous variable that corresponds to the certainty of the agents respect to which strategy is best. The opinions transform into actions by making the selection of an strategy a stochastic event with a probability regulated by the opinion. A certain regard for the previous round payoff is included but the main update rules of the opinion are given by a model inspired in social interchanges. We find that the fixed points of the dynamics of the coupled model are different from those of the evolutionary game or the opinion models alone. Furthermore, new features emerge such as the independence of the fraction of cooperators with respect to the topology of the social interaction network or the presence of a small fraction of extremist players.

  5. Fuzzy Aspect Based Opinion Classification System for Mining Tourist Reviews

    Directory of Open Access Journals (Sweden)

    Muhammad Afzaal

    2016-01-01

    Full Text Available Due to the large amount of opinions available on the websites, tourists are often overwhelmed with information and find it extremely difficult to use the available information to make a decision about the tourist places to visit. A number of opinion mining methods have been proposed in the past to identify and classify an opinion into positive or negative. Recently, aspect based opinion mining has been introduced which targets the various aspects present in the opinion text. A number of existing aspect based opinion classification methods are available in the literature but very limited research work has targeted the automatic aspect identification and extraction of implicit, infrequent, and coreferential aspects. Aspect based classification suffers from the presence of irrelevant sentences in a typical user review. Such sentences make the data noisy and degrade the classification accuracy of the machine learning algorithms. This paper presents a fuzzy aspect based opinion classification system which efficiently extracts aspects from user opinions and perform near to accurate classification. We conducted experiments on real world datasets to evaluate the effectiveness of our proposed system. Experimental results prove that the proposed system not only is effective in aspect extraction but also improves the classification accuracy.

  6. The interplay of self-reflection, social interaction and random events in the dynamics of opinion flow in two-party democracies

    Lichtenegger, Klaus; Hadzibeganovic, Tarik

    2016-01-01

    We propose a continuous process opinion formation model to study the dynamics of a multi-level relationship between voters, political parties, and facts in two-party democratic elections. In our model, opinions can take any real value between two extremes and an unaligned, moderate opinion state without a preference. Starting with a random opinion configuration, individual voter opinions evolve and change over time due to self-reflection, inter-personal communication, external media influence, and noise. Parties are influenced by their own ideologies, facts, and voters’ opinions. Elections are held periodically and the party that is closer in opinion to the majority of voters forms the new government. The government policy is then expected to be in proximity to the voter opinions and the policies of the currently ruling political party. We analyze the tension of opinions as a measure of how dramatically opinions can disagree within a given sample of voters and the success of the government and parties as the degree of coincidence between the policies and facts. Our model generates realistic quasi-periodic alternations between incumbents and challengers that are typical for two-party systems. Moreover, our model shows that relative to other voters’ strategies, conscious voting can lead to more successful governments of not only fact-oriented but also pragmatic and balanced political parties, irrespective of the strategies of the competing opposition parties. In addition, our simulations uncover several interesting features including less victories for strictly ideological or fact-oriented parties unless they include some aspects of populism or pragmatism. In this sense, our model can also describe situations where election outcomes are not necessarily based on votes for the current programs of competing parties and their placement on relevant issues, but instead result from voters’ dissatisfaction with the previous government and the votes against it.

    2006-08-01

    For more than 110 years hands of surgeons have been treated before a surgical procedure in order to reduce the bacterial density. The kind and duration of treatment, however, has changed significantly over time. Recent scientific evidence suggests a few changes with the aim to optimize both the efficacy and the dermal tolerance. Aim of this article is the presentation and discussion of new insights in surgical hand disinfection. A hand wash should be performed before the first disinfection of a day, ideally at least 10 min before the beginning of the disinfection as it has been shown that a 1 min hand wash significantly increases skin hydration for up to 10 min. The application time may be as short as 1.5 min depending on the type of hand rub. Hands and forearms should be kept wet with the hand rub for the recommended application time in any case. A specific rub-in procedure according to EN 12791 has been found to be suitable in order to avoid untreated skin areas. The alcohol-based hand rub should have a proven excellent dermal tolerance in order to ensure appropriate compliance. Considering these elements in clinical practice can have a significant impact to optimize the high quality of surgical hand disinfection for prevention of surgical site infections.

  8. Social Influence and the Collective Dynamics of Opinion Formation

    2013-01-01

    Social influence is the process by which individuals adapt their opinion, revise their beliefs, or change their behavior as a result of social interactions with other people. In our strongly interconnected society, social influence plays a prominent role in many self-organized phenomena such as herding in cultural markets, the spread of ideas and innovations, and the amplification of fears during epidemics. Yet, the mechanisms of opinion formation remain poorly understood, and existing physics-based models lack systematic empirical validation. Here, we report two controlled experiments showing how participants answering factual questions revise their initial judgments after being exposed to the opinion and confidence level of others. Based on the observation of 59 experimental subjects exposed to peer-opinion for 15 different items, we draw an influence map that describes the strength of peer influence during interactions. A simple process model derived from our observations demonstrates how opinions in a gro...

  9. Rise of an alternative majority against opinion leaders

    2016-01-01

    We investigate the role of opinion leaders or influentials in the collective behavior of a social system. Opinion leaders are characterized by their unidirectional influence on other agents. We employ a model based in Axelrod's dynamics for cultural interaction among social agents that allows for non-interacting states. We find three collective phases in the space of parameters of the system, given by the fraction of opinion leaders and a quantity representing the number of available states: one ordered phase having the state imposed by the leaders; another nontrivial ordered phase consisting of a majority group in a state orthogonal or alternative to that of the opinion leaders, and a disordered phase, where many small groups coexist. We show that the spontaneous rise of an alternative group in the presence of opinion leaders depends on the existence of a minimum number of long-range connections in the underlying network. This phenomenon challenges the common idea that influentials are important to spreading...

  10. Ranking System for Opinion Mining of Features from Review Documents

    Full Text Available With the exponential growth of the web there has been explosive increase in the user generated contents in the form of customer reviews, blogs, discussion forums, social networks etc. Most of the contents are stored in the form of unstructured or semi structured data from where distillation of knowledge is a challenging task. In this paper we propose a feature wise opinion mining system which first extracts features from user generated contents, then determines the intensity of the opinions by giving emphasis to the modifier of the words, which expresses opinions. It finds the numeric score of all the features using Senti-WordNet and then calculates the overall orientation of the feature to determine how intense the opinion is for both the positive and negative features. The positive and negative features are identified by extracting the associated modifiers and opinions. The summary is presented by specifying the features in descending order of importance.

    2014-07-01

    The da Vinci surgical system was developed by Intuitive Surgical Inc. in the United States as an endoscopic surgical device to assist remote control surgeries. In 1998, the Da Vinci system was first used for cardiothoracic procedures. Currently a combination of robot-assisted internal thoracic artery harvest together with coronary artery bypass grafting (CABG) through a mini-incision (ThoraCAB) or totally endoscopic procedures including anastomoses under robotic assistance (TECAB) are being conducted for the treatment of coronary artery diseases. With the recent advances in catheter interventions, hybrid procedures combining catheter intervention with ThoraCAB or TECAB are anticipated in the future.On the other hand, with the decrease in number of coronary artery bypass surgeries, the share of valvular surgeries is expected to increase in the future. Among them, mitral valvuloplasty for mitral regurgitation is anticipated to be conducted mainly by low-invasive procedures, represented by minimally invasive cardiac surgery( MICS) and robot-assisted surgery. Apart from the intrinsic good surgical view, robotic-assisted systems offer additional advantages of the availability of an amplified view and the easy to observe the mitral valve in the physiological position. Thus, robotic surgical surgeries that make complicated procedures easier are expected to accomplish further developments in the future. Furthermore, while the number of surgeries for atrial septal defects has decreased dramatically following the widespread use of Amplatzer septal occluder, robotic surgery may become a good indication for cases in which the Amplatzer device is not indicated. In Japan, clinical trial of the da Vinci robotic system for heart surgeries has been completed. Statutory approval of the da Vinci system for mitral regurgitation and atrial septal defects is anticipated in the next few years.

    2009-04-01

    Scholars suspect that public policies affect public opinion, but the empirical evidence is mixed, and contemporary theories advance offsetting predictions. This study examines two allegedly similar private investment account programs that differ in politically relevant ways. Statistical analyses show that owners of Individual Retirement Accounts (IRAs) and Health Savings Accounts (HSAs) experience policy feedback effects, but in opposite directions. More specifically, matched comparisons of respondents in a national survey indicate that IRA participants are more likely to favor Social Security privatization than individuals without IRAs. In contrast, HSA participants are less likely to prefer consumer-driven health coverage in which individuals are empowered to make choices. Overall, the findings suggest that policies alter public opinion preferences but that the effects depend on programmatic design and performance.

    Management of intrauterine synechiae in a context of infertility remains a challenge, in spite of hysteroscopic microsurgery progress. There is no published prospective study to be used as a guideline. Anatomic, but most of all functional prognosis are directly correlated to the severity of adhesions and the number of surgical procedures required to complete treatment. Complications during surgery are not infrequent, but are well known and often benign. Obstetrical complications are much less frequent but often severe (abnormal placentation, uterine rupture). Recurrences are common enough to impose a systematic second-look diagnostic hysteroscopy. However, the benefit gained by the recovery of fertility (either spontaneous or not) remains superior, in my opinion, to the risks of the surgical management.

    Pakistan is a patriarchal society in which male opinion leaders play an important role in determining health-seeking behaviors pertaining to family planning (FP) among their respective communities. This research focuses on cataloguing the perceptions of opinion leaders (clergymen, health professionals, and social workers) about the barriers for using services and practical solutions for promoting FP in the slums of Karachi, Pakistan. A qualitative study using an open-ended, semistructured interview schedule with hypothetical scenarios and in-depth interviews with a purposive sample of 45 opinion leaders (25 mosque imams/clergymen, 12 nonallopathic health professionals, and eight social workers/activists) was conducted in 2006-2007 in Karachi, Pakistan. Transcripts were coded thematically utilizing NVivo by using an adapted constant comparison analysis process as described by Strauss and Corbin. Seven key themes were derived from the in-depth interviews. Five themes provide insight into the opinion leaders' perceptions of barriers to FP and modern contraception methods. Among the barriers religious taboos and cultural pressures were particularly note-worthy. Two themes offered opportunities for more effective development and implementation of FP programs. It is evident from the study that opinion leaders in the community and the clergy lack the understanding of the importance of birth spacing. However, because they have a great deal of influence on the community at large, it is imperative to interact with them to build their capacity in order to propagate the messages of FP and improve maternal health and reproductive health in general.

    Surgical skills training varies greatly between institutions and is often left to students to approach independently. Although many studies have examined single interventions of skills training, no data currently exists about the implementation of surgical skills assessment as a component of the medical student surgical curriculum. We created a technical skills competition and evaluated its effect on student surgical skill development. Second-year medical students enrolled in the surgery clerkship voluntarily participated in a surgical skills competition consisting of knot tying, laparoscopic peg transfer, and laparoscopic pattern cut. Winning students were awarded dinner with the chair of surgery and a resident of their choice. Individual event times and combined times were recorded and compared for students who completed without disqualification. Disqualification included compromising cutting pattern, dropping a peg out of the field of vision, and incorrect knot tying technique. Timed performance was compared for 2 subsequent academic years using Mann-Whitney U test. Overall, 175 students competed and 71 students met qualification criteria. When compared by academic year, 2015 to 2016 students (n = 34) performed better than 2014 to 2015 students (n = 37) in pattern cut (133s vs 167s, p = 0.040), peg transfer (66s vs 101s, p skills competition improves student technical performance. Further research is needed regarding long-term benefits of surgical competitions for medical students. Copyright © 2017 Association of Program Directors in Surgery. Published by Elsevier Inc.

    The Ising or Potts models of ferromagnetism have been widely used to describe locally interacting social or economic systems. We consider a related model, introduced by Sznajd to describe the evolution of consensus in the scale-free networks with the tunable strength (noted by Q) of community structure. In the Sznajd model, the opinion or state of any spins can only be changed by the influence of neighbouring pairs of similar connection spins. Such pairs can polarize their neighbours. Using asynchronous updating, it is found that the smaller the community strength Q, the larger the slope of the exponential relaxation time distribution. Then the effect of the initial up- spin concentration p as a function of the final all up probability E is investigated by taking different initialization strategies, the random node-chosen initialization strategy has no difference under different community strengths, while the strategies of community node-chosen initialization and hub node-chosen initialization are different in final probability under different Q, and the latter one is more effective in reaching final state.

    Full Text Available Objective : The Delhi State Drug Policy was adopted in 1994 following which the first Essential Medicines List (EML was developed in 1996. The Delhi State Essential Medicines Formulary was brought out in 1997. A need was felt to revise the formulary to match with the EML as the EML is renewed every 2 years. Materials and Methods : A survey was undertaken to elicit the opinions of the doctors practicing in the state on the usefulness of the formulary before revising and printing the updated version. The survey covered dispensaries, 10-20 bedded hospitals, 100-bedded hospitals and two tertiary care hospitals. Discussions were focused on questionnaires on attitudes toward adopting Essential Medicines Formulary using a 10-point scale. Results : Of the 200 doctors approached, only 90 doctors completed the questionnaire. Sixty-nine respondents (76.6% had received the copy of the formulary. Most practitioners welcomed the formulary and were satisfied with the coverage and selection of the medicines. Most respondents (76.9% agreed that a well-developed formulary would improve the quality of the public health care system, although they had reservations about the authority, relevance and effect on professional autonomy. Conclusion : About 74% of the respondents used the formulary in clinical practice as a source of medicine information, which makes its regular revision necessary.

Participants were asked about beliefs about purchasing assault weapons, beliefs about bringing handguns to college campuses and beliefs about contributing factors that lead to gun violence. Participants completed surveys online. The findings showed that overall 54 % of respondents believed that military assault weapons should be banned and 53 % agree that teachers should be allowed to carry a registered handgun on campus. There were statistically significant differences between males and females on these issues. For instance, females believed military assault weapons and high capacity magazines should be banned more than 1.9 times (p = .004) p gun violence were decline in parenting and family values (17 %), gang involvement (14 %), bullying (13.8 %) and guns being easy to obtain (13.8 %).

    Full Text Available Objectives: Our aim is to describe the current clinical practice related to the management of septic shock (SS. Methods: Review of medical literature using the MEDLINE database. Articles were selected according to their relevancy to the objective and according to the author’s opinion. Summary of the findings: The outcome from SS is dependent on an early recognition and a sequential implementation of time-sensitive goal-directed therapies. The goals of the resuscitation are rapid restoration of micro circulation and improved organ tissue perfusion. Clinical and laboratory markers are needed to assess the adequacy of the treatments. Initial resuscitation involves the use of isotonic solutions (>60ml/kg either crystalloid (normal saline or colloid infusion often followed by vasoactive medications. Altered pharmacokinetics and pharmacodynamics responses dictate that vasoactive agents should be adjusted to achieve predetermined goals. An assessment of central venous pressure complements clinical and serological findings to tailor therapies. Elective airway instrumentation and mechanical ventilation as well as adjunctive therapy with stress dose of corticosteroid are indicated in selected populations. In neonates, a special attention to the presence of electrolyte imbalance and increase pulmonary vascular resistance needs to be considered early. Conclusions: Septic shock hemodynamic is a changing process that requires frequent assessment and therapeutic adjustments.

  1. Adherence to surgical care improvement project measures and post-operative surgical site infections.

    2012-08-01

    Surgical site infection (SSI) is unequivocally morbid and costly. The estimated 300,000 SSIs annually in the United States represent the second most common infection among surgical patients, prolong hospitalization by 7-10 days, and have an estimated annual incremental cost of $1 billion. The mortality rate associated with SSI is 3%, with about three quarters of deaths being attributable directly to the infection. Prevention is possible for the most part, and concerted effort has been made to limit these infections, arguably to little effect. Review of pertinent English-language literature. Numerous risk factors for SSI and tactics for prevention have been described, but efforts to bundle these tactics into an effective, comprehensive prevention program have been disappointing. Numerous studies now demonstrate that the Surgical Care Improvement Program (SCIP), which focused on process improvement rather than outcomes, has been ineffective despite governmental support, financial penalties for non-compliance, and consequent widespread implementation. Required reporting has increased awareness of the problem of SSI, but just as the complexity of SSI risk, pathogenesis, and preventions reflects the complexity of the disease, many other factors must be taken into account, including the skill and knowledge of the surgical team and promulgation of a culture of quality and safety in surgical patient care.

    We present a model of interacting multiple choices of opinions. At each step of the process, a listener is persuaded by his/her neighbour, the lobbyist, to modify his/her opinion on two different choices of event. Whether or not the listener will be convinced by the lobbyist depends on the difference between his/her opinion with that of the lobbyist, and with that of the revealed social opinion (the social pressure). If the listener is convinced, he/she will modify his/her opinion and update his/her revealed preference, and proceed to persuade his/her next neighbour. If the listener is not convinced by the lobbyist, he/she will retain his/her revealed preference, and try to persuade the lobbyist to change his/her opinion. In this case, the direction of opinion propagation is reversed. A consensus is reached when all the revealed preference is the same. Our numerical results show that consensus can always be attained in this model. However, the time needed to achieve consensus, or the so-called convergence tim...

  3. Continuous Opinion Dynamics Under Bounded Confidence:. a Survey

    Science.gov (United States)

    Lorenz, Jan

    Models of continuous opinion dynamics under bounded confidence have been presented independently by Krause and Hegselmann and by Deffuant et al. in 2000. They have raised a fair amount of attention in the communities of social simulation, sociophysics and complexity science. The researchers working on it come from disciplines such as physics, mathematics, computer science, social psychology and philosophy. In these models agents hold continuous opinions which they can gradually adjust if they hear the opinions of others. The idea of bounded confidence is that agents only interact if they are close in opinion to each other. Usually, the models are analyzed with agent-based simulations in a Monte Carlo style, but they can also be reformulated on the agent's density in the opinion space in a master equation style. The contribution of this survey is fourfold. First, it will present the agent-based and density-based modeling frameworks including the cases of multidimensional opinions and heterogeneous bounds of confidence. Second, it will give the bifurcation diagrams of cluster configuration in the homogeneous model with uniformly distributed initial opinions. Third, it will review the several extensions and the evolving phenomena which have been studied so far, and fourth it will state some open questions.

    Under certain circumstances such as lack of information or bounded rationality, human players can take decisions on which strategy to choose in a game on the basis of simple opinions. These opinions can be modified after each round by observing own or others payoff results but can be also modified after interchanging impressions with other players. In this way, the update of the strategies can become a question that goes beyond simple evolutionary rules based on fitness and become a social issue. In this work, we explore this scenario by coupling a game with an opinion dynamics model. The opinion is represented by a continuous variable that corresponds to the certainty of the agents respect to which strategy is best. The opinions transform into actions by making the selection of an strategy a stochastic event with a probability regulated by the opinion.

    Current sexuality education programs vary widely in the accuracy of content, emphasis, and effectiveness. Data have shown that not all programs are equally effective for all ages, races and ethnicities, socioeconomic groups, and geographic areas. Studies have demonstrated that comprehensive sexuality education programs reduce the rates of sexual activity, sexual risk behaviors (eg, number of partners and unprotected intercourse), sexually transmitted infections, and adolescent pregnancy. One key component of an effective program is encouraging community-centered efforts. In addition to counseling and service provision to individual adolescent patients, obstetrician-gynecologists can serve parents and communities by supporting and assisting sexuality education. Because of their knowledge, experience, and awareness of a community's unique challenges, obstetrician-gynecologists can be an important resource for sexuality education programs.

    2015-04-01

    Networks were successfully applied to describe complex systems, such as brain, climate, processes in society. Recently a socio-physical problem of opinion-dynamics was studied using network techniques. We present the toy-model of opinion-formation based on the physical model of advection-diffusion. We consider spreading of the opinion on the fixed subject, assuming that opinion on society is binary: if person has opinion then the state of the node in the society-network equals 1, if the person doesn't have opinion state of the node equals 0. Opinion can be spread from one person to another if they know each other, or in the network-terminology, if the nodes are connected. We include into the system governed by advection-diffusion equation the external field to model such effects as for instance influence from media. The assumptions for our model can be formulated as the following: 1.the node-states are influenced by the network structure in such a way, that opinion can be spread only between adjacent nodes (the advective term of the opinion-dynamics), 2.the network evolution can have two scenarios: -network topology is not changing with time; -additional links can appear or disappear each time-step with fixed probability which requires adaptive networks properties. Considering these assumptions for our system we obtain the system of equations describing our model-dynamics which corresponds well to other socio-physics models, for instance, the model of the social cohesion and the famous voter-model. We investigate the behavior of the suggested model studying "waiting time" of the system, time to get to the stable state, stability of the model regimes for different values of model parameters and network topology.

  11. Louis Pasteur surgical revolution.

    Toledo-Pereyra, Luis H

    2009-01-01

    Louis Pasteur (1822-1895) is considered the most notable medical scientist of his time and perhaps one of the most distinguished of all times in the history of medicine. From Dole in France to Paris, from a student of crystals to "living ferments," and from chemistry to biology and medicine, Pasteur changed the world for the benefit of humanity. The genius of Pasteur dealt with the most pressing issues of his time, basing the germ theory on the effects that microorganisms had on fermentation and putrefaction of organic matter, which gave birth to the science of bacteriology. Many other difficult problems in medicine and biology were tackled by Pasteur, culminating in the spectacular results seen with the treatment of rabies. Surgery was no exception to the scientific conquests of Pasteur. The transformation of the surgical world arose from the antiseptic concepts of Lister that were based on the germ theory of the disease, which had been derived from the germ theory of fermentation and putrefaction discovered by Pasteur. The acceptance of these principles represented the surgical revolution brought on by the science of Pasteur, a revolution that is now accepted in our daily care of surgical patients.

    Surgical attire helps protect patients from microorganisms that may be shed from the hair and skin of perioperative personnel. The updated AORN "Guideline for surgical attire" provides guidance on scrub attire, shoes, head coverings, and masks worn in the semirestricted and restricted areas of the perioperative setting, as well as how to handle personal items (eg, jewelry, backpacks, cell phones) that may be taken into the perioperative suite. This article focuses on key points of the guideline to help perioperative personnel adhere to facility policies and regulatory requirements for attire. The key points address the potential benefits of wearing scrub attire made of antimicrobial fabric, covering the arms when in the restricted area of the surgical suite, removing or confining jewelry when wearing scrub attire, disinfecting personal items that will be taken into the perioperative suite, and sending reusable attire to a health care-accredited laundry facility after use. Perioperative RNs should review the complete guideline for additional information and for guidance when writing and updating policies and procedures.

  18. A Silent Safety Program

    Science.gov (United States)

    Goodin, James Ronald

    2006-01-01

    NASA's Columbia Accident Investigation Board (CAIB) referred 8 times to the NASA "Silent Safety Program." This term, "Silent Safety Program" was not an original observation but first appeared in the Rogers Commission's Investigation of the Challenger Mishap. The CAIB on page 183 of its report in the paragraph titled 'Encouraging Minority Opinion,' stated "The Naval Reactor Program encourages minority opinions and "bad news." Leaders continually emphasize that when no minority opinions are present, the responsibility for a thorough and critical examination falls to management. . . Board interviews revealed that it is difficult for minority and dissenting opinions to percolate up through the agency's hierarchy. . ." The first question and perhaps the only question is - what is a silent safety program? Well, a silent safety program may be the same as the dog that didn't bark in Sherlock Holmes' "Adventure of the Silver Blaze" because system safety should behave as a devil's advocate for the program barking on every occasion to insure a critical review inclusion. This paper evaluates the NASA safety program and provides suggestions to prevent the recurrence of the silent safety program alluded to in the Challenger Mishap Investigation. Specifically targeted in the CAM report, "The checks and balances the safety system was meant to provide were not working." A silent system safety program is not unique to NASA but could emerge in any and every organization. Principles developed by Irving Janis in his book, Groupthink, listed criteria used to evaluate an organization's cultural attributes that allows a silent safety program to evolve. If evidence validates Jams's criteria, then Jams's recommendations for preventing groupthink can also be used to improve a critical evaluation and thus prevent the development of a silent safety program.

    One of the solutions aimed at improving the functioning of the healthcare system in Poland is to introduce patients' co-payment for public healthcare services. In all countries where the healthcare system is at a high level there already exists a co-payment system and it is regarded by many specialists as a necessary and indispensable condition for the proper functioning of healthcare. The aim of this study was to show respondents' attitudes and opinions regarding the proposal of introduction co-payments as and additional form of financing medical care. The questionnaire survey covered a group of 2,409 persons (50.7% men and 49.3% women). Most respondents, despite the overall rising dissatisfaction with the quality and availability of medical services do not see the need for co-payments. The opinion about the implementation of co-payments. The opinion about the implementation of co-payments depends on many factors, to the most important belong age, education, place of residence and income. More often, the co-payments is in favour of young people in good health condition, who live in big cities, having a university degree and determining their financial situation as good. Before the introduction of co-payment - certain social groups, which would be exempt from additional fees, should be specified. To the highest costs that patients are able to carry belong: paying for a home visit of family doctor or specialist, for surgical procedures, and for complex tests performed during the hospital stay (including computed tomography, magnetic resonance imaging).

    Surgical wounds that become infected are often debrided because clinicians believe that removal of this necrotic or infected tissue will expedite wound healing. There are numerous methods available but no consensus on which one is most effective for surgical wounds. The aim of this review is to determine the effect of different methods of debridement on the rate of debridement and healing of surgical wounds. We developed a search strategy to search the following electronic databases: Wounds Group Specialised Trials Register (searched 3/3/08) , Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library, 2008, issue 1), MEDLINE (1950 to February Week 3 2008 ), EMBASE (1980 to 2008 Week 09) and CINHAL (1982 to February Week 4 2008). We checked the citations within obtained studies to identify additional papers and also relevant conference proceedings. We contacted manufactures of wound debridement agents to ascertain the existence of published, unpublished and ongoing trials. Our search was not limited by language or publication status. We included relevant randomised controlled trials (RCT) with outcomes including at least one of the following: time to complete debridement, or time to complete healing. Two authors independently reviewed the abstracts and titles obtained from the search, two extracted data independently using a standardised extraction sheet, and two independently assessed methodological quality. One author was involved in all stages of the data collection and extraction process, thus ensuring continuity. Five RCTs were eligible for inclusion; all compared treatments for infected surgical wounds and reported time required to achieve a clean wound bed (complete debridement). One trial compared an enzymatic agent (Streptokinase/streptodornase) with saline-soaked dressings and reported the time to complete debridement. Four of the trials compared the effectiveness of dextranomer beads or paste with other products (different comparator

    The landscape of surgical training is changing. The anticipated increase in the numbers of surgical trainees and the shift to competency-based surgical training places pressures on an already stretched health service. With these pressures in mind, we explored trainers' and trainees' experiences of surgical training in a less traditional rotation, an outer metropolitan hospital. We considered practice-based learning theories to make meaning of surgical training in this setting, in particular Actor-network theory. We adopted a qualitative approach and purposively sampled surgical trainers and trainees to participate in individual interviews and focus groups respectively. Transcripts were made and thematically analysed. Institutional human research ethics approval was obtained. Four surgical trainers and fourteen trainees participated. Almost without exception, participants' report training needs to be well met. Emergent inter-related themes were: learning as social activity; learning and programmatic factors; learning and physical infrastructure; and, learning and organizational structure. This outer metropolitan hospital is suited to the provision of surgical training with the current rotational system for trainees. The setting offers experiences that enable consolidation of learning providing a rich and varied overall surgical training program. Although relational elements of learning were paramount they occurred within a complex environment. Actor-network theory was used to give meaning to emergent themes acknowledging that actors (both people and objects) and their interactions combine to influence training quality, shifting the focus of responsibility for learning away from individuals to the complex interactions in which they work and learn.

  4. Scientific Opinion on infectious salmon anaemia (ISA

    2012-11-01

    Full Text Available Atlantic salmon is the only species in which the disease infectious salmon anaemia (ISA has been observed naturally. Initial reports of findings of infectious salmon anaemia virus (ISAV before 2002, did not distinguish between non virulent HPR0 and virulent HPRΔ viruses, thus making interpretation of older findings difficult in the light of current knowledge. Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the relationship between HPR0 and HPRΔ, the risk of HPRΔ ISAV emerging from HPR0 ISAV, and possible risk factors for such an emergence. HPR0 ISAV does not cause clinical disease in Atlantic salmon; however, it causes a transient subclinical infection and replicates mainly in gills. There is no evidence for HPR0 ISAV leading to natural infection and replication in fish species other than Atlantic salmon. Virulent ISAV have deletions in the HPR region of the HE gene and they have either an insertion or the Q266L mutation in the F gene. The most plausible hypothesis is that virulent ISAV (HPRΔ is derived from HPR0 ISAV. This is further supported by the close association between the genetic relatedness and spatio-temporal distances of virus strains in solitary outbreaks. Epidemiological and historical data from solitary disease outbreaks indicates that the risk of HPRΔ ISAV emerging from HPR0 is low, but not negligible. The risk factors for HPRΔ emergence from HPR0 are unknown. Nevertheless, any factor that affects virus replication or host susceptibility could possibly influence the risk of emergence. More research is needed on the drivers for transition from HPR0 to HPRΔ and factors affecting host susceptibility and thereby emergence of clinical disease. A quantitative assessment of the different evolutionary forces for ISA would be useful, as well as the prevalence of ISAV HPR0 in farmed and wild Atlantic salmon.

    Full Text Available Following a request from the European Commission, the EFSA Panel on Dietetic Products, Nutrition and Allergies (NDA was asked to carry out the additional assessment for ‘Rooster Combs Extract’ (RCE as a food ingredient in the context of Regulation (EC No 258/97, taking into account the comments and objections of a scientific nature raised by Member States. Rooster combs extract results from a production process involving enzymatic hydrolysis of rooster combs and subsequent filtration, concentration and precipitation steps. The principle constituents of RCE are the glycosaminoglycans hyaluronic acid, chondroitin sulphate A and dermatan sulphate. The applicant intends to add RCE to a number of dairy products with a recommended maximum intake of 80 mg RCE per portion and per day. The target population is the general population, with the exception of pregnant women, children and people with adverse reactions to sodium hyaluronate and/or avian protein. In the high intake scenario for “consumers only”, the highest daily intake would occur in adults in Belgium (0.788 g. The highest intake scenario for “all subjects” was estimated for adolescents in Denmark (0.427 g/day. The Panel notes that no adverse effects were observed at the highest tested dose of 600 mg/kg bw per day in a 90-day oral toxicity study in rats. Considering the nature, the natural occurrence and previous consumption of RCE constituents, the Panel is of the opinion that the margin between the intended as well as the estimated maximum possible intake of RCE in relation to the highest dose administered to rats without adverse effects in a subchronic oral toxicity study is sufficient. The Panel concludes that the novel food ingredient, Rooster Comb Extract, is safe under the proposed uses and use levels.

    2016-11-01

    With the advent of online networks, societies have become substantially more interconnected with individual members able to easily both maintain and modify their own social links. Here, we show that active network maintenance exposes agents to confirmation bias, the tendency to confirm one's beliefs, and we explore how this bias affects collective opinion formation. We introduce a model of binary opinion dynamics on a complex, fluctuating network with stochastic rewiring and we analyze these dynamics in the mean-field limit of large networks and fast link rewiring. We show that confirmation bias induces a segregation of individuals with different opinions and stabilizes the consensus state. We further show that bias can have an unusual, nonmonotonic effect on the time to consensus and this suggests a novel avenue for large-scale opinion manipulation.

    Opinion evolution mechanism can be captured by physics modeling approaches. In this context, a kinetic equation is established by defining a generalized displace (cognitive-level), a driving force and the related generalized potential, information quantity, altitude. It has been shown that the details of opinion evolution depends the type of the driving force, self-dominated driving or environment- dominated driving. In the former case, the participants can have their altitudes changed in the process of competition between the self-driving force and environment-driving force. In the latter case, all of the participants are pulled by the environment. Some regularity behind the dynamics of opinion is also revealed, for instance, the information entropy decays with time in a special way, etc. the results may help us to get some deep understandings to formation of a public opinion.

    Many models have been proposed to analyze the evolution of opinion structure due to the interaction of individuals in their social environment. Such models analyze the spreading of ideas both in completely interacting backgrounds and on social networks, where each person has a finite set of interlocutors.Moreover also the investigation on the topological structure of social networks has been object of several analysis, both from the theoretical and the empirical point of view. In this framework a particularly important area of study regards the community structure inside social networks.In this paper we analyze the reciprocal feedback between the opinions of the individuals and the structure of the interpersonal relationships at the level of community structures. For this purpose we define a group based random network and we study how this structure co-evolve with opinion dynamics processes. We observe that the adaptive network structure affects the opinion dynamics process helping the consensus formation. Th...

    Huet, Sylvie

    2014-01-01

    We propose a new opinion dynamic model based on the experiments and results of Wood et al (1996). We consider pairs of individuals discussing on two attitudinal dimensions, and we suppose that one dimension is important, the other secondary. The dynamics are mainly ruled by the level of agreement on the main dimension. If two individuals are close on the main dimension, then they attract each other on the main and on the secondary dimensions, whatever their disagreement on the secondary dimension. If they are far from each other on the main dimension, then too much proximity on the secondary dimension is uncomfortable, and generates rejection on this dimension. The proximity is defined by comparing the opinion distance with a threshold called attraction threshold on the main dimension and rejection threshold on the secondary dimension. With such dynamics, a population with opinions initially uniformly drawn evolves to a set of clusters, inside which secondary opinions fluctuate more or less depending on thres...

    2014-01-01

    In this work we study the critical behavior of a three-state ($+1$, $-1$, $0$) opinion model with independence. Each agent has a probability $q$ to act as independent, i.e., he/she can choose his/her opinion independently of the opinions of the other agents. On the other hand, with the complementary probability $1-q$ the agent interacts with a randomly chosen individual through a kinetic exchange. Our analytical and numerical results show that the independence mechanism acts as a noise that induce an order-disorder transition at critical points $q_{c}$ that depend on the individuals' flexibility. For a special value of this flexibility the system undergoes a transition to an absorbing state with all opinions $0$.

    2016-05-01

    Full Text Available with the increase of opinionated reviews on the web, automatically analyzing and extracting knowledge from those reviews is very important. However, it is a challenging task to be done manually. Opinion mining is a text mining discipline that automatically performs such a task. Most researches done in this field were focused on English texts with very limited researches on Arabic language. This scarcity is because there are a lot of obstacles in Arabic. The aim of this paper is to develop a novel semantic feature-based opinion mining framework for Arabic reviews. This framework utilizes the semantic of ontologies and lexicons in the identification of opinion features and their polarity. Experiments showed that the proposed framework achieved a good level of performance compared with manually collected test data.

    Full Text Available The authors prove the necessity of carrying out opinion polls for the assessment of town-planning decisions and the effectiveness of municipal authorities’ activity in the field of creating a comfortable environment. The authors come up with an idea that no decision can be made without preliminary studying public opinion as it is a question of public health and subjective perception of life and environmental space. In case, the inhabitants do not trust the authorities and each other, it is impossible to create modern living standards, to solve important social problems and to realize significant for the population town-planning projects. Therefore, opinions, interests, offers and preferences of citizens concerning developed town-planning projects taking into account the balance of the main indexes, evaluation test of realized state programs of housing construction, social, cultural and household facilities and the degree of satisfaction of the population with the actions of the local authorities are to become the main subject of further research of the sociologists.

    2007-01-01

    Surgical innovations are often introduced for their expected long-term benefits, but the decision to abandon the existing treatment must be based on the available short-term data and rational judgment. We present a framework for monitoring the introduction of a surgical intervention with long......-term consequences and failure-time endpoints. The framework is based on Bayesian methods, and formally combines study data, clinical opinion, and external evidence to construct a posterior survival function from which intuitive summary statistics can be extracted to aid decision making.

    The present study was oriented to the leadership theme focussing nurses inside surgical ward unities. As a theoretical reference, the authors used the Situational Leadership Model proposed by Hersey and Blanchard. This study aimed at analysing the correspondence between the opinions of nurses and auxiliary personnel about the leadership style exerted by nurses in the surgical ward unit regarding the six categories of the assistance activity that were studied. Authors noticed that nurses, from the two studied hospitals, adopted the directive leadership styles (E2/selling or E1/telling) with the auxiliary personnel.

  3. Referral for a bariatric surgical consultation: it is time to set a standard of care.

    2009-05-01

    Indications for bariatric surgery have been clear for some time and many would say that they are conservative. Unfortunately few eligible candidates seek or are referred for bariatric surgery, with less than 1% currently treated annually. In recent years, the evidence base supporting surgical therapy has strengthened with demonstrable improvements in both safety and efficacy. We now have evidence of remarkable improvements in health, quality of life, and increased life expectancy. There is continued frustration with the poor efficacy of non-surgical therapies and no indication that this is about to change. A caring physician should, as best care, refer the seriously ill morbidly obese patient for a surgical opinion. It is no different from their obligation to adequately manage type-2 diabetes, depression or unstable angina. Currently, even discussion of a surgical referral is optional. It is time we articulated and defined a group of patients where referral for a surgical opinion is no longer merely an option but a physician's responsibility as best care for the patient. It is time to provide leadership towards the delivery of better care for these patients.

    2014-05-01

    Surgical wound irrigation has long been debated as a potentially critical intraoperative measure taken to prevent the development of surgical site infection (SSI). Unlike many other SSI prevention efforts, there are no official practice guidelines or recommendations from any major medical group for the practice of surgical irrigation. As a result, practitioner implementation of the 3 major irrigation variables (delivery method, volume, and solution additives) can differ significantly. A focus group of key thought leaders in infection prevention and epidemiology convened recently to address the implications of different surgical irrigation practices. They identified an urgent need for well-designed clinical trials investigating surgical irrigation practices, improved collaboration between surgical personnel and infection preventionists, and examination of existing evidence to standardize irrigation practices. The group agreed that current published data are sufficient to support the elimination of antibiotic solutions for surgical irrigation; the avoidance of surfactants for surgical irrigation; and the use of sterile normal saline, sterile water, and 1 medical device containing a sterile 0.05% chlorhexidine gluconate solution followed by sterile saline. Given the current lack of sufficient evidence identifying ideal delivery method and volume choices, expert opinion must be relied on to guide best practice.

    According to differences in patient characteristics, surgical performance, or used surgical technological resources, surgical interventions have high variability. No methods for the generation and comparison of statistical 'mean' surgical procedures are available. The convenience of these models is to provide increased evidence for clinical, technical, and administrative decision-making. Based on several measurements of patient individual surgical treatments, we present a method of how to calculate a statistical 'mean' intervention model, called generic Surgical Process Model (gSPM), from a number of interventions. In a proof-of-concept study, we show how statistical 'mean' procedure courses can be computed and how differences between several of these models can be quantified. Patient individual surgical treatments of 102 cataract interventions from eye surgery were allocated to an ambulatory or inpatient sample, and the gSPMs for each of the samples were computed. Both treatment strategies are exemplary compared for the interventional phase Capsulorhexis. Statistical differences between the gSPMs of ambulatory and inpatient procedures of performance times for surgical activities and activity sequences were identified. Furthermore, the work flow that corresponds to the general recommended clinical treatment was recovered out of the individual Surgical Process Models. The computation of gSPMs is a new approach in medical engineering and medical informatics. It supports increased evidence, e.g. for the application of alternative surgical strategies, investments for surgical technology, optimization protocols, or surgical education. Furthermore, this may be applicable in more technical research fields, as well, such as the development of surgical workflow management systems for the operating room of the future.

    An anonymous questionnaire-based survey was used to determine current practices and opinions of senior health professionals working in Western Australian (WA) hospitals performing gynaecological procedures, regarding the routine use of histopathology for products of conception (POC) obtained either from the surgical management of miscarriage or termination of pregnancy. Sixty-one senior health professionals completed the survey. Tissue histopathology on POC was routinely requested for miscarriage and termination of pregnancy (TOP) by 87 and 59% of respondents, respectively. Respondents listed the main reasons for requesting routine histopathology as avoidance of misdiagnosis, medico-legal and quality assurance. There were inconsistent practices among WA health professionals regarding sending POC for histopathology; 63% of gynaecology head of departments recommend the introduction of state or national guidelines for the use of histopathology in the surgical management of miscarriages or terminations of pregnancy.

    We report 3 cases with a vertical incomitance in upgaze, narrowing of palpebral fissure, and pseudo-overaction of both inferior oblique muscles. Surgery consisted of an elevation of both lateral rectus muscles with an asymmetrical weakening. A satisfactory result was achieved in 2 cases, whereas a Lambda syndrome appeared in the other case. The surgical technique of upper-insertion with a recession of both lateral rectus muscles improved vertical incomitance in 2 of the 3 patients; however, a residual deviation remains in the majority of cases.

    The surgical treatment of complications of diverticulitis remains most challenging. A review of twenty years' experience with one hundred fifteen cases is presented with one proved anastomotic leak and no deaths. Interval primary resection with anastomosis for chronic recurrent disease including colovesical fistula and mesocolic abscess was proved sate with low morbidity. The three-stage procedure for perforated diverticulitis with spreading peritonitis or pericolic abscess was associated with a high rate of complications and morbidity. An aggressive approach with resection without anastomosis in two stages is indicated.

  14. A consensus opinion model based on the evolutionary game

    Yang, Han-Xin

    2016-08-01

    We propose a consensus opinion model based on the evolutionary game. In our model, both of the two connected agents receive a benefit if they have the same opinion, otherwise they both pay a cost. Agents update their opinions by comparing payoffs with neighbors. The opinion of an agent with higher payoff is more likely to be imitated. We apply this model in scale-free networks with tunable degree distribution. Interestingly, we find that there exists an optimal ratio of cost to benefit, leading to the shortest consensus time. Qualitative analysis is obtained by examining the evolution of the opinion clusters. Moreover, we find that the consensus time decreases as the average degree of the network increases, but increases with the noise introduced to permit irrational choices. The dependence of the consensus time on the network size is found to be a power-law form. For small or larger ratio of cost to benefit, the consensus time decreases as the degree exponent increases. However, for moderate ratio of cost to benefit, the consensus time increases with the degree exponent. Our results may provide new insights into opinion dynamics driven by the evolutionary game theory.

  15. Rise of an alternative majority against opinion leaders

    2016-03-01

    We investigate the role of opinion leaders or influentials in the collective behavior of a social system. Opinion leaders are characterized by their unidirectional influence on other agents. We employ a model based on Axelrod's dynamics for cultural interaction among social agents that allows for non-interacting states. We find three collective phases in the space of parameters of the system, given by the fraction of opinion leaders and a quantity representing the number of available states: one ordered phase having the state imposed by the leaders; another nontrivial ordered phase consisting of a majority group in a state orthogonal or alternative to that of the opinion leaders, and a disordered phase, where many small groups coexist. We show that the spontaneous rise of an alternative group in the presence of opinion leaders depends on the existence of a minimum number of long-range connections in the underlying network. This phenomenon challenges the common idea that influentials are fundamental to propagation processes in society, such as the formation of public opinion.

    This paper addresses the need to deal with and control public opinion and rumors. Existing strategies to control public opinion include degree, random, and adaptive bridge control strategies. In this paper, we use the HK model to present a public opinion control strategy based on public authority (PA). This means utilizing the influence of expert or high authority individuals whose opinions we control to obtain the optimum effect in the shortest time possible and thus reach a consensus of public opinion. Public authority (PA) is only influenced by individuals' attributes (age, economic status, and education level) and not their degree distribution; hence, in this paper, we assume that PA complies with two types of public authority distribution (normal and power-law). According to the proposed control strategy, our experiment is based on random, degree, and public authority control strategies in three different social networks (small-world, scale-free, and random) and we compare and analyze the strategies in terms of convergence time (T), final number of controlled agents (C), and comprehensive efficiency (E). We find that different network topologies and the distribution of the PA in the network can influence the final controlling effect. While the effect of PA strategy differs in different network topology structures, all structures achieve comprehensive efficiency with any kind of public authority distribution in any network. Our findings are consistent with several current sociological phenomena and show that in the process of public opinion/rumor control, considerable attention should be paid to high authority individuals.

    In general, university-based global health initiatives have tended to focus on expanding access to primary care. In the past, surgical programs may have been characterized by sporadic participation with little educational focus. However, there have been some notable exceptions with plastic surgery volunteer missions. We offer another model of regularly scheduled surgical trips to rural Haiti in plastic and general surgery. The goal of these trips is to reduce the burden of surgical disease and ultimately repair every cleft lip/palate in Haiti. Another principal objective is to accelerate the training of American residents through increased case load and personal interaction with attending surgeons in a concentrated period. Diversity of the case load and the overall number of surgeries performed by residents in a typical surgical trip outpaces the experiences available during a typical week in an American hospital setting. More importantly, we continue to provide ongoing training to Haitian nurses and surgeons in surgical techniques and postoperative care. Our postoperative complication rate has been relatively low. Our follow-up rates have been lower than 70% despite intensive attempts to maintain continued communication with our patients. Through our experiences in surgical care in rural Haiti, we were able to quickly ramp up our trauma and orthopedic surgical care immediately after the earthquake. Project Medishare and the University of Miami continue to operate a trauma and acute care hospital in Port au Prince. The hospital provides ongoing orthopedic, trauma, and neurosurgical expertise from the rotating teams of American surgeons and training of Haitian surgeons in modern surgical techniques. We believe that surgical residencies in the United States can improve their training programs and reduce global surgical burden of disease through consistent trips and working closely with country partners.

    Urology training programs seek to identify ideal candidates with the potential to become competent urologic surgeons. It is unclear whether innate technical ability has a role in this selection process. We aimed to determine whether there are any innate differences in baseline urologic technical skills among medical students. Second-year medical students from the University of Toronto were recruited for this study and stratified into surgical and non-surgical cohorts based on their reported career aspirations. After a pre-test questionnaire, subjects were tested on several urologic surgical skills: laparoscopy, cystoscopy and robotic surgery. Statistical analysis was performed using chi-squared test, student t-tests and Spearman's correlation where appropriate. A total of 29 students participated in the study and no significant baseline differences were found between cohorts with respect to demographics and prior surgical experience. For laparoscopic skills, the surgical cohort outperformed the non-surgical cohort on several exercises: Lap Beans Missed (4.9 vs. 9.3, p robotic surgery performance metrics: Task Time (50.6 vs. 76.3, p robotics, may differ between early trainees interested in a surgical career compared to those interested in a non-surgical career. Further studies are required to illicit what impact such differences have on future performance and competence.

    The objectives of this study were to describe the rate and predictors of surgical site infection (SSI) after gynecologic cancer surgery and identify any association between SSI and postoperative outcome. Patients with endometrial, cervical, or ovarian cancers from 2005 to 2011 were identified from the American College of Surgeons National Surgical Quality Improvement Program. The extent of surgical intervention was categorized into modified surgical complexity scoring (MSCS) system. Univariate and multivariate logistic regression analyses were used. Odds ratios were adjusted for patient demographics, comorbidities, preoperative laboratory values, and operative factors. Of 6854 patients, 369 (5.4%) were diagnosed with SSI. Surgical site infection after laparotomy was 3.5 times higher compared with minimally invasive surgery (7% vs 2%; P Surgical site infection was associated with longer mean hospital stay and higher rate of reoperation, sepsis, and wound dehiscence. Surgical site infection was not associated with increased risk of acute renal failure or 30-day mortality. These findings were consistent in subset of patients with deep or organ space SSI. Seven percent of patients undergoing laparotomy for gynecologic malignancy developed SSI. Surgical site infection is associated with longer hospital stay and more than 5-fold increased risk of reoperation. In this study, we identified several risk factors for developing SSI among gynecologic cancer patients. These findings may contribute toward identification of patients at risk for SSI and the development of strategies to reduce SSI rate and potentially reduce the cost of care in gynecologic cancer surgery.

    2016-06-01

    The aim of the present article was to systematically review the ethics of surgical innovation and introduce the components of the learning health care system to guide future research and debate on surgical innovation.Although the call for evidence-based practice in surgery is increasingly high on the agenda, most surgeons feel that the format of the randomized controlled trial is not suitable for surgery. Innovation in surgery has aspects of, but should be distinguished from both research and clinical care and raises its own ethical challenges.To answer the question "What are the main ethical aspects of surgical innovation?", we systematically searched PubMed and Embase. Papers expressing an opinion, point of view, or position were included, that is, normative ethical papers.We included 59 studies discussing ethical aspects of surgical innovation. These studies discussed 4 major themes: oversight, informed consent, learning curve, and vulnerable patient groups. Although all papers addressed the ethical challenges raised by surgical innovation, surgeons hold no uniform view of surgical innovation, and there is no agreement on the distinction between innovation and research. Even though most agree to some sort of oversight, they offer different alternatives ranging from the formation of new surgical innovation committees to establishing national registries. Most agree that informed consent is necessary for innovative procedures and that surgeons should be adequately trained to assure their competence to tackle the learning curve problem. All papers agree that in case of vulnerable patients, alternatives must be found for the informed consent procedure.We suggest that the concept of the learning health care system might provide guidance for thinking about surgical innovation. The underlying rationale of the learning health care system is to improve the quality of health care by embedding research within clinical care. Two aspects of a learning health care system might

    Full Text Available Background: The case triage practice workflow model was used to manage incoming cases on a telepathology-enabled surgical pathology quality assurance (QA service. Maximizing efficiency of workflow and the use of pathologist time requires detailed information on factors that influence telepathologists′ decision-making on a surgical pathology QA service, which was gathered and analyzed in this study. Materials and Methods: Surgical pathology report reviews and telepathology service logs were audited, for 1862 consecutive telepathology QA cases accrued from a single Arizona rural hospital over a 51 month period. Ten university faculty telepathologists served as the case readers. Each telepathologist had an area of subspecialty surgical pathology expertise (i.e. gastrointestinal pathology, dermatopathology, etc. but functioned largely as a general surgical pathologist while on this telepathology-enabled QA service. They handled all incoming cases during their individual 1-h telepathology sessions, regardless of the nature of the organ systems represented in the real-time incoming stream of outside surgical pathology cases. Results: The 10 participating telepathologists′ postAmerican Board of pathology examination experience ranged from 3 to 36 years. This is a surrogate for age. About 91% of incoming cases were immediately signed out regardless of the subspecialty surgical pathologists′ area of surgical pathology expertise. One hundred and seventy cases (9.13% were deferred. Case concurrence rates with the provisional surgical pathology diagnosis of the referring pathologist, for incoming cases, averaged 94.3%, but ranged from 88.46% to 100% for individual telepathologists. Telepathology case deferral rates, for second opinions or immunohistochemistry, ranged from 4.79% to 21.26%. Differences in concordance rates and deferral rates among telepathologists, for incoming cases, were significant but did not correlate with years of experience as a

  5. Does the weather influence public opinion about climate change?

    Donner, S. D.; McDaniel, J.

    2010-12-01

    Public opinion in North America about the science of anthropogenic climate change and the motivation for policy action has been variable over the past twenty years. The trends in public opinion over time have been attributed the general lack of pressing public concern about climate change to a range of political, economic and psychological factors. One driving force behind the variability in polling data from year to year may be the weather itself. The difference between what we “expect” - the climate - and what we “get” - the weather - can be a major source of confusion and obfuscation in the public discourse about climate change. For example, reaction to moderate global temperatures in 2007 and 2008 may have helped prompt the spread of a “global cooling” meme in the public and the news media. At the same time, a decrease in the belief in the science of climate change and the need for action has been noted in opinion polls. This study analyzes the relationship between public opinion about climate change and the weather in the U.S. since the mid-1980s using historical polling data from several major organizations (e.g. Gallup, Pew, Harris Interactive, ABC News), historical monthly air temperature (NCDC) and a survey of opinion articles from major U.S. newspapers (Washington Post, New York Times, Wall Street Journal, Houston Chronicle, USA Today). Seasonal and annual monthly temperature anomalies for the northeastern U.S and the continental U.S are compared with available national opinion data for three general categories of questions: i) Is the climate warming?, ii) Is the observed warming due to human activity?, and iii) Are you concerned about climate change? The variability in temperature and public opinion over time is also compared with the variability in the fraction of opinion articles in the newspapers (n ~ 7000) which express general agreement or disagreement with IPCC Summary for Policymakers consensus statements on climate change (“most of

    Full Text Available A feared complication of temporary surgical drain placement is from the technical error of accidentally suturing the surgical drain into the wound. Postoperative discovery of a tethered drain can frequently necessitate return to the operating room if it cannot be successfully removed with nonoperative techniques. Formal wound exploration increases anesthesia and infection risk as well as cost and is best avoided if possible. We present a minimally invasive surgical technique that can avoid the morbidity associated with a full surgical wound exploration to remove a tethered drain when other nonoperative techniques fail.

    Full Text Available Scar formation is an inevitable consequence of wound healing from either a traumatic or a surgical intervention. The aesthetic appearance of a scar is the most important criteria to judge the surgical outcome. An understanding of the anatomy and wound healing along with experience, meticulous planning and technique can reduce complications and improve the surgical outcome. Scar revision does not erase a scar but helps to make it less noticeable and more acceptable. Both surgical and non-surgical techniques, used either alone or in combination can be used for revising a scar. In planning a scar revision surgeon should decide on when to act and the type of technique to use for scar revision to get an aesthetically pleasing outcome. This review article provides overview of methods applied for facial scar revision. This predominantly covers surgical methods.

    Gout is an inflammatory joint disease associated with deposition of monosodium urate crystals in the bones forming the joints, in periarticular tissues and in other organs. The disease is one of the most frequent causes of disability. This paper presents the case of a 57-year-old male patient treated for generalised gout. A "clinical mask" suggesting another disease was the cause of making the correct diagnosis only six years after the occurrence of the first manifestations. The patient, with high values of inflammatory markers, severe pain and advanced joint destruction, was given an aggressive anti-inflammatory treatment. The unsatisfactory effect of the conservative treatment forced the authors to perform surgical resection of the gouty nodules in the hands. After several operations the function of the hand joints operated on, appearance of the hands and the quality of the patient's life improved significantly.

    2009-01-01

    Neuronavigation and stereotaxy are techniques designed to help neurosurgeons precisely localize different intracerebral pathological processes by using a set of preoperative images (CT, MRI, fMRI, PET, SPECT etc.). The development of computer assisted surgery was possible only after a significant technological progress, especially in the area of informatics and imagistics. The main indications of neuronavigation are represented by the targeting of small and deep intracerebral lesions and choosing the best way to treat them, in order to preserve the neurological function. Stereotaxis also allows lesioning or stimulation of basal ganglia for the treatment of movement disorders. These techniques can bring an important amount of confort both to the patient and to the neurosurgeon. Neuronavigation was introduced in Romania around 2003, in four neurosurgical centers. We present our five-years experience in neuronavigation and describe the main principles and surgical techniques.

  14. Key opinion leaders: used as a marketing tool by drug companies.

    Science.gov (United States)

    2012-06-01

    In marketing, "key opinion leaders" are used to influence purchasing behaviour through their perceived position of authority. In drug marketing, key opinion leaders are renowned physicians and other healthcare professionals on whom the medical profession rely when forming an opinion on a drug or practice. Pharmaceutical companies use key opinion leaders as marketing tools to promote their drugs or influence the decisions of regulatory agencies and other institutions. Opinion leaders are carefully handled and their management is often outsourced to specialised marketing agencies.

    This report has been developed as an integral part of the PVMapper project, funded by the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy’s SunShot program. The objective of the SunShot program is to reduce the total costs of solar energy systems. The scope of PVMapper is to develop a geographic information system (GIS) based project planning tool to identify optimal utility-scale solar facility sites. The specific objectives of the project are to 1) develop the software on an open-source platform; 2) integrate the appropriate data sets and GIS layers; 3) include a measure of social risk and public acceptance; 4) enable customization of variable weights; 5) provide a free and accessible platform for software download; and 6) provide a sustainability plan to ensure future relevance of the software. When completed, PVMapper is intended to be used by solar developers, Authorities Having Jurisdiction (AHJs), and other interested parties. This project supports SunShot’s objective by reducing the non-hardware balance of system costs (“soft costs”) for utility-scale solar project development. In order to accomplish the third project objective – including a measure of social risk and public acceptance within PVMapper – the project team has developed a time-series public opinion survey, administered yearly over the course of the three-year project. This report highlights the results and preliminary analyses from the second survey in this series. While the results of this survey are valuable to both PVMapper and future utility-scale solar development, the time-series design is extremely important. The completion of the series enables the extension of the dataset to much richer information. For example, the research team altered this iteration to sharpen the focus on specific topics (those posing potentially higher risks) and target specific locations in the oversample (such as communities near existing facilities). Using similar

  16. The Dynamics of Public Opinion Regarding SETI: A Mathematical Model

    History abounds with examples of extreme fluctuations in attitude towards the idea of extraterrestrial life. Presently, the understanding of the public's opinion is more important than ever because the Search is dependent on such support, both morally and financially. It has been recognized that the dynamics of public opinion can be described by stochastic equations. We present the results of a mathematical simulation of the dynamics of public opinion regarding SETI based on the stochastic model of Weidlich and Haag . Critical discussion of the basic parameters of the model will precede the discussion of the results. The crucial role of the ``parameter of adaptation'' ,a, describing the readiness of the average individual to adhere to the current opinion of the majority is pointed out. The danger of high values of this parameter (a ``dogmatic'' society), is demonstrated for both a smooth and a shocked (e.g. by discovery of an ET signal) evolution of reality. In both regimes, the reaction of a high a society is less conformant with reality and less predictable. It is argued that a reasonable policy can decrease the a parameter of society and maintain optimal evolution of public opinion. This project was supported by the NSF/REU grant AST-9820555.

  17. Boltzmann-type control of opinion consensus through leaders.

    The study of formations and dynamics of opinions leading to the so-called opinion consensus is one of the most important areas in mathematical modelling of social sciences. Following the Boltzmann-type control approach recently introduced by the first two authors, we consider a group of opinion leaders who modify their strategy accordingly to an objective functional with the aim of achieving opinion consensus. The main feature of the Boltzmann-type control is that, owing to an instantaneous binary control formulation, it permits the minimization of the cost functional to be embedded into the microscopic leaders' interactions of the corresponding Boltzmann equation. The related Fokker-Planck asymptotic limits are also derived, which allow one to give explicit expressions of stationary solutions. The results demonstrate the validity of the Boltzmann-type control approach and the capability of the leaders' control to strategically lead the followers' opinion. © 2014 The Author(s) Published by the Royal Society.

  18. Are public opinion polls self-fulfilling prophecies?

    Full Text Available Psychologists have long observed that people conform to majority opinion, a phenomenon sometimes referred to as the ‘bandwagon effect’. In the political domain people learn about prevailing public opinion via ubiquitous polls, which may produce a bandwagon effect. Newer types of information – published probabilities derived from prediction market contract prices and aggregated polling summaries – may have similar effects. Consequently, polls can become self-fulfilling prophecies whereby majorities, whether in support of candidates or policies, grow in a cascading manner. Despite increased attention to whether the measurement of public opinion can itself affect public opinion, the existing empirical literature is surprisingly limited on the bandwagon effects of polls. To address this gap, we conducted an experiment on a diverse national sample in which we randomly assigned people to receive information about different levels of support for three public policies. We find that public opinion as expressed through polls affects individual-level attitudes, although the size of the effect depends on issue characteristics.

    While climate scientists have developed high resolution data sets on the distribution of climate risks, we still lack comparable data on the local distribution of public climate change opinions. This paper provides the first effort to estimate local climate and energy opinion variability outside the United States. Using a multi-level regression and post-stratification (MRP) approach, we estimate opinion in federal electoral districts and provinces. We demonstrate that a majority of the Canadian public consistently believes that climate change is happening. Belief in climate change's causes varies geographically, with more people attributing it to human activity in urban as opposed to rural areas. Most prominently, we find majority support for carbon cap and trade policy in every province and district. By contrast, support for carbon taxation is more heterogeneous. Compared to the distribution of US climate opinions, Canadians believe climate change is happening at higher levels. This new opinion data set will support climate policy analysis and climate policy decision making at national, provincial and local levels.

    In July 1994, the Executive Director for Operations of the US Nuclear Regulatory Commission (NRC) appointed a Special Review Panel to assess the Differing Professional View or Opinion (DPV/DPO) process, including its effectiveness, how well it is understood by employees, and the organizational climate for having such views aired and properly decided. An additional area within this review was to address the effectiveness of the DPO procedures as they pertain to public access and confidentiality. Further, the Panel was charged with the review of the submittals completed since the last review to identify employees who made significant contributions to the agency or to the public health and safety but had not been adequately recognized for this contribution. The report presents the Special Review Panel`s evaluation of the NRC`s current process for dealing with Differing Professional Views or Opinions. Provided in this report are the results of an employee opinion survey on the process; highlights and suggestions from interviews with individuals who had submitted a Differing Professional View or Opinion, as well as with agency managers directly involved with the Differing Professional Views or Opinions process; and the Special Review Panel`s recommendations for improving the DPV/DPO process.
