Published: July 2016

AbstractAn experimental work is conducted on counter flow plate fin compact heat exchanger using offset strip fin under different mass flow rates. The training, testing, and validation set of data has been collected by conducting experiments. Next, artificial neural network merged with Genetic Algorithm (GA) utilized to measure the performance of plate-fin compact heat exchanger. The main aim of present research is to measure the performance of plate-fin compact heat exchanger and to provide full explanations. An artificial neural network predicted simulated data, which verified with experimental data under 10–20% error. Then, the authors examined two well-known global search techniques, simulated annealing and the genetic algorithm. The proposed genetic algorithm and Simulated Annealing (SA) results have been summarized. The parameters are impartially important for good results. With the emergence of a new data-driven modeling technique, Neuro-fuzzy based systems are established in academic and practical applications. The neuro-fuzzy interference system (ANFIS) has also been examined to undertake the problem related to plate-fin heat exchanger performance measurement under various parameters. Moreover, Parallel with ANFIS model and Artificial Neural Network (ANN) model has been created with emphasizing the accuracy of the different techniques. A wide range of statistical indicators used to assess the performance of the models. Based on the comparison, it was revealed that technical ANFIS improve the accuracy of estimates in the small pool and tropical ANN.Highlights Performance of compact plate fin heat exchanger has been measured. Predicted data given by ANN has been verified by simulation data and the experimental data. Depicted the applications of optimization methods upon fin heat exchanger.

AbstractIntroduction Diverticular disease of the colon (DDC) is the fifth most common gastrointestinal disease in developed Western countries, with mortality rates of 2.5 per 100,000 inhabitants per year.Objective The objective of this study is to compare the occurrence of complications, conversion rate, use of stoma, deaths and time of hospitalization among patients undergoing rectosigmoidectomy for DDC and patients undergoing the same surgery for other reasons.Method This was an observational retrospective comparative study. This study was approved by the ethics committee of the Hospital Felicio Rocho – Minas Gerais, Brazil – and the data were obtained from the same hospital database.Results The groups were classified according to age, gender, presence of comorbidities, and ASA classification. There was no evidence indicating a significant difference between groups. In this analysis, no perioperative complications were observed and there was no need for a stoma, and no deaths or fistulas occurred.Conclusion Elective laparoscopic surgical treatment of DDC in the analyzed group showed no difference in complications, duration of surgery and hospitalization time versus control group. Therefore, the laparoscopic surgical treatment of diverticular disease translates into an excellent tool for both the surgeon and the patient.

AbstractBackgroundHigh‐dominant frequency (DF) and continuous complex fractionated atrial electrogram (CFAE) sites as surrogates for localized sources maintaining atrial fibrillation (AF) are potential AF ablation targets. This study aimed to evaluate the characteristics of a rotational activation at high‐DF and continuous CFAE sites in AF patients.MethodsThirty‐two consecutive AF patients (5 paroxysmal and 27 non‐paroxysmal) underwent ablation using the NavX system. When AF continued after circumferential pulmonary vein isolation (PVI), high‐DF sites of ≥8 Hz and continuous CFAE sites (fractionated intervals ≤50 ms) in the left (LA) and right (RA) atria were recorded using a high‐density 20‐pole circular mapping catheter for 5 s and ablated.ResultsThe atrial electrogram characteristics during AF were assessed. A total of 2383 AF beats from 89 high‐DF and 19 continuous CFAE sites were investigated. A rotational activation of high‐DF and continuous CFAE sites was also observed at 4% and 3% of LA, and 4% and 4% of RA sites, respectively. However, rotational activation was identified in 29 (91%) of 32 patients (mean 3.0±2.6 beats per patient, 80% in the LA). Procedural endpoints were achieved in 26 (81%) of 32 patients: AF termination (n=2) and AF cycle length slowing of >10% (n=26).ConclusionsRotational activation could be identified in high‐DF and continuous CFAE sites during AF, but the documentation was limited. Therefore, only limited effects of rotational activation ablation at high‐DF and/or continuous CFAE sites following PVI could be concluded.

Published: July 2016

AbstractSocial media have been increasingly adopted for organizational purposes but their operational implications are not well understood. Firms’ social media initiatives might facilitate information flow and knowledge sharing within and across organizations, strengthening firm‐customer interaction, and improving internal and external collaboration. In this research we empirically examine the impact of social media initiatives on firms’ operational efficiency and innovativeness. Taking the resource‐based view of firms’ information capability, we consider firms’ social media initiatives as strategic resources for operational improvement. We posit that firms’ social media initiatives enhance dynamic knowledge‐sharing routines through an information‐rich social network, leading to both operational efficiency and innovativeness. Collecting secondary data in a longitudinal setting from multiple sources, we construct dynamic panel data (DPD) models. Based on system generalized method of moments (GMM) estimation, we show that firms’ social media initiatives improve operational efficiency and innovativeness. We identify the importance of an information‐rich social network to the creation of knowledge‐based advantage through firms’ social media initiatives, and discuss the theoretical and managerial implications from the perspective of operations management.

Published: July 2016

AbstractBackgroundSubstantial numbers of U.S. military veterans who served in recent conflicts experience mild traumatic brain injury. Data suggest that as many as 25% of veterans do not have a comprehensive traumatic brain injury evaluation to determine a diagnosis and develop a plan to treat symptoms. Technologies like clinical video telehealth offer a potential means to overcome travel distance and other barriers that can impact veteran receipt of a comprehensive traumatic brain injury evaluation after a positive screening; however, little is known about implementing clinical video telehealth in this context.ObjectiveTo examine the perspectives of Veterans Health Administration health care providers on implementing clinical video telehealth technology for the assessment and treatment of mild traumatic brain injury among veterans of Operation Enduring Freedom, Operation Iraqi Freedom, and Operation New Dawn.DesignQualitative; semistructured interviews.SettingVeterans Health Administration Polytrauma System of Care.ParticipantsTwenty‐six providers who participated in a Veterans Health Administration Rehabilitation and Prosthetic Services Teleconsultation Pilot Project for administering comprehensive traumatic brain injury evaluations over clinical video telehealth.MethodsSemistructured interviews that used content‐analytic techniques to assess provider experiences implementing clinical video telehealth for veterans with traumatic brain injury, including inhibiting factors and best practices to administer comprehensive traumatic brain injury evaluations.ResultsThe most commonly reported inhibiting factors to implementing clinical video telehealth for traumatic brain injury evaluation and treatment included scheduling, setting up the clinic, and conducting physical examinations over a virtual modality. To enhance clinical video telehealth implementation, participants described best practices including establishing solid communication and relationships with staff, building rapport with patients, and recognizing the unique needs of patients with traumatic brain injury.ConclusionsImplementing clinical video telehealth programs involves coordinating multiple steps with providers at different sites, highlighting the need for effective communication. Provider‐patient communication also emerged as vital to successful clinical video telehealth implementation. These findings suggest that providers would benefit from efforts to build communication competencies.Level of EvidenceNot applicable.
Innovations With 3‐Dimensional Printing in Physical Medicine and Rehabilitation: A Review of the Literature
Authors: Lunsford Christopher , Grindle Garrett , Salatin Benjamin , Dicianno Brad E. 
Published: July 2016

AbstractCreated more than 30 years ago, 3‐dimensional printing (3DP) has recently seen a meteoric rise in interest within medicine, and the field of Physical Medicine and Rehabilitation is no exception. Also called additive manufacturing (AM), the recent increase in the use of 3DP is likely due to lower‐cost printers as well as breakthroughs in techniques and processing. This thematic narrative review serves to introduce the rehabilitation professional to 3DP technology and how it is being applied to orthoses, prostheses, and assistive technology (AT). The basics of the technology, as well as the benefits and challenges of using it within the rehabilitation framework, are described. Proponents of the technology suggest that 3DP offers not only a better way to make devices, but a better way to make improved devices. However, the strength of this claim has not been properly tested by the current literature. This narrative review evaluates the evidence and provides a discussion of possible implications for the rehabilitation professional.

Published: July 2016

AbstractIntroduction:To assess the volume of patients and the composition of their injuries and illnesses that presented to an emergency department (ED) close to the epicenter of an earthquake that occurred in a seismically prepared area.Methods:A retrospective analysis of data abstracted from charts and ED logs for patient census and types of injuries and illnesses of the patients who presented in the ED of a community hospital before and after the earthquake (6.8 Richter scale) that occurred in 1994 in Los Angeles. Illnesses were classified as trauma- and non-trauma related. Data were compared with epidemiological profiles of earthquakes in seismically prepared and unprepared areas.Results:A statistically significant increase in ED patient census over baseline lasted 11 days. There was a large increase in the number of traumatic injuries such as lacerations and orthopedic injuries during the first 48 hours. Beginning on the third day after the event, primary care conditions predominated. When the effects of the LA quake were compared with those of similar Richter magnitude and disruptive capability, the ED epidemiology profile was similar to those in seismically unprepared areas, except for the total number of casualties.Conclusion:The majority of patients with traumatic injuries presented within the first 48 hours. The increase relative to baseline lasted 11 days. Efforts to develop disaster response systems from resources outside the disaster-stricken area should focus on providing mostly primary care assistance. Communities in seismically prepared areas could require external medical assistance for their EDsfor up to two weeks following the event.
Hospital Responses to Acute-Onset Disasters: A Review
Authors: Milsten Andrew 
Published: July 2016

AbstractIntroduction:Hospitals the world over have been involved in disasters, both internal and external. These two types of disasters are independent, but not mutually exclusive. Internal disasters are isolated to the hospital and occur more frequently than do external disasters. External disasters affect the community as well as the hospital. This paper first focuses on common problems encountered during acute-onset disasters, with regards to hospital operations and caring for victims. Specific injury patterns commonly seen during natural disasters are reviewed. Second, lessons learned from these common problems and their application to hospital disaster plans are reviewed.Methods:An extensive review of the available literature was conducted using the computerized databases Medline and Healthstar from 1977 through March 1999. Articles were selected if they contained information pertaining to a hospital response to a disaster situation or data on specific disaster injury patterns. Selected articles were read, abstracted, analyzed, and compiled.Results:Hospitals continually have difficulties and failures in several major areas of operation during a disaster. Common problem areas identified include communication and power failures, water shortage and contamination, physical damage, hazardous material exposure, unorganized evacuations, and resource allocation shortages.Conclusions::Lessons learned from past disaster-related operational failures are compiled and reviewed. The importance and types of disaster planning are reviewed.
Ally or Adversary? Using Media Systems for Public Health
Authors: Ball-Rokeach Sandra J. , Loges William E. 
Published: July 2016

AbstractThe media system controls information resources that public health agencies may wish to use to accomplish their goals, particularly in a crisis. The resources of the public health system sometimes are prized by the media system, and this provides opportunities for public health agencies to gain access to the media. This paper reviews the goals and resources of the media system as they relate to the mission of public health agencies in the periods before, during, and after a public health crisis. The various media are reviewed with attention to the role each can play for different purposes and at different stages of a crisis. The importance of presenting health information in the form of stories is emphasized, with specific advice regarding the attributes of an effective story.
Community Collaboration in Disaster: The Role of Voluntary Agencies
Authors: Bowenkamp Christine Dusty 
Published: July 2016

AbstractAlthough the United States has been impacted by numerous devastating disasters over the last 10 years, there have been only limited efforts between the governmental and non-profit/voluntary organizations to meet the multiple disaster health and mental health needs of the community. Too often, responding organizations compete to provide services, duplicate efforts, and frequently under-estimate the need for services.Recent efforts have been undertaken by The American Red Cross and other groups to resolve this issue. Governmental and community-based organizations have been invited to participate in planning sessions to pre-identify roles and responsibilities, as well as to exchange key information about the services each group can and does provide.These efforts have lead to an increased awareness of the potential problems and the development of cohesive plans to provide medical and emotional support services to impacted communities. This has led to improved care for those with serious injuries or psychological crisis, while those with less critical problems have been managed appropriately without needing to be immediately referred to overcrowded emergency departments or physician's offices.

AbstractIntroduction:The discussions in this theme provided an opportunity to address the unique hazards facing the Pacific Rim.Methods:Details of the methods used are provided in the preceding paper. The chairs moderated all presentations and produced a summary that was presented to an assembly of all of the delegates. Since the findings from the Theme 3 and Theme 7 groups were similar, the chairs of both groups presided over one workshop that resulted in the generation of a set of action plans that then were reported to the collective group of all delegates.Results:The main points developed during the presentations and discussion included: (1) communication, (2) coordination, (3) advance planning and risk assessment, and (4) resources and knowledge.Discussion:Action plans were summarized in the following ideas: (1) plan disaster responses including the different types, identification of hazards, focusing training based on experiences, and provision of public education; (2) improve coordination and control; (3) maintain communications, assuming infrastructure breakdown; (4) maximize mitigation through standardized evaluations, the creation of a legal framework, and recognition of advocacy and public participation; and (5) provide resources and knowledge through access to existing therapies, the media, and increasing and decentralizing hospital inventories.Conclusions:The problems in the Asia-Pacific rim are little different from those encountered elsewhere in the world. They should be addressed in common with the rest of the world.

AbstractIntroduction:Change must begin with education. Theme 8 explored issues that need attention in Disaster Medicine education.Methods:Details of the methods used are provided in the introductory paper. The chairs moderated all presentations and produced a summary that was presented to an assembly of all of the delegates. The chairs then presided over a workshop that resulted in the generation of a set of action plans that then were reported to the collective group of all delegates.Results:Main points developed during the presentations and discussion included: (1) formal education, (2) standardized definitions, (3) integration (4) evaluation of programs and interventions, (5) international cooperation, (6) identifying the psychosocial consequences of disaster, (7) meaningful research, and (8) hazard, impact, risk and vulnerability analysis.Discussion:Three main components of the action plans were identified as evaluation, research, and education. The action plans recommended that: (1) education on disasters should be formalized, (2) evaluation of education and interventions must be improved, and (3) meaningful research should be promulgated and published for use at multiple levels and that applied research techniques be the subject of future conferences.Conclusions:The one unanimous conclusion was that we need more and better education on the disaster phenomenon, both in its impacts and in our response to them. Such education must be increasingly evidence-based.
Toxic Trauma
Authors: Moles T.M. , Baker D.J. 
Published: July 2016

AbstractHazardous materials (HAZMAT) carry many inherent dangers. Such materials are distributed widely in industrial and military sites. Toxic trauma (TT) denotes the complex of systemic and organ injury caused by toxic agents. Often, TT is associated with other injuries that also require the application of life-support techniques. Rapid onset of acute respiratory failure and consequent cardiovascular failure are of primary concern. Management of TT casualties is dependent upon the characteristics of the toxic agents involved and on the demographics surrounding the HAZMAT incident.Agents that can produce TT possess two pairs of salient characteristics: (1) causality (toxicity and latency), and (2) EMS system (persistency and transmissibility). Two characteristics of presentations are important: (1) incident presentation, and (2) casualty presentation. In addition, many of these agents complicate the processes associated with anaesthesia and must be dealt with. Failure of recognition of these factors may result in the development of respiratory distress syndromes and multiorgan system failure, or even death.
