Measurement of novel biomarkers of neuronal injury and cerebral oxygenation after routine vaginal delivery versus cesarean section in term infants.

AIMS
It remains unclear if mode of delivery can have any impact on the neonatal brain. Our aim was to determine in term newborns any differences based on mode of delivery in either neuronal injury biomarkers, phosphorylated axonal neurofilament heavy chain (pNF-H) and ubiquitin C-terminal hydrolase (UCHL1), or brain oxygenation values, regional cerebral tissue oxygen saturation (CrSO2) and cerebral fractional tissue oxygen extraction (CFOE).


METHODS
An Institutional Review Board approved prospective observational pilot study of well newborns. Serum pNF-H and UCHL1 levels were measured on the day following delivery. CrSO2 values along with CFOE values were also measured using near-infrared spectroscopy (NIRS) and pulse oximetry.


RESULTS
There were 22 subjects, 15 born vaginally and seven born by cesarean section. No difference was found in mean pNF-H (107.9±54.3 pg/mL vs. 120.2±43.3 pg/mL, P=0.66) or mean UCHL1 (4.0±3.5 pg/mL vs. 3.0±2.2 pg/mL, P=0.68). No difference was found in mean CrSO2 (80.8±5.3% vs. 80.8±5.6%, P=0.99) or mean CFOE (0.17±0.06 vs. 0.15±0.08, P=0.51).


CONCLUSIONS
We found no difference in neuronal injury markers between term neonates born vaginally compared to those born by cesarean section. From a neurologic standpoint, this supports current obstetric practice guidelines that emphasize vaginal birth as the preferred delivery method whenever possible.
Initial outcome and efficacy of "kyphoplasty" in the treatment of painful osteoporotic vertebral compression fractures.

STUDY DESIGN
An Institutional Review Board-approved Phase I efficacy study of inflatable bone tamp usage in the treatment of symptomatic osteoporotic compression fractures.


OBJECTIVES
To evaluate the safety and efficacy of inflatable bone tamp reduction and cement augmentation, "kyphoplasty," in the treatment of painful osteoporotic vertebral compression fractures.


SUMMARY OF BACKGROUND DATA
Osteoporotic compression fractures can result in progressive kyphosis and chronic pain. Traditional treatment for these patients includes bed rest, analgesics, and bracing. Augmentation of vertebral compression fractures with polymethylmethacrylate, "vertebroplasty," has been used to treat pain. This technique, however, makes no attempt to restore the height of the collapsed vertebral body. Kyphoplasty is a new technique that involves the introduction of inflatable bone tamps into the vertebral body. Once inflated, the bone tamps restore the vertebral body back toward its original height while creating a cavity that can be filled with bone cement.


PATIENTS AND METHODS
Seventy consecutive kyphoplasty procedures were performed in 30 patients. The indications included painful primary or secondary osteoporotic vertebral compression fractures. Mean duration of symptoms was 5.9 months. Symptomatic levels were identified by correlating the clinical data with MRI findings. Perioperative variables and bone tamp complications or issues were recorded and analyzed. Preoperative and postoperative radiographs were compared to calculate the percentage height restored. Outcome data were obtained by comparing preoperative and latest postoperative SF-36 data.


RESULTS
At the completion of the Phase I study there were no major complications related directly to use of this technique or use of the inflatable bone tamp. In 70% of the vertebral bodies kyphoplasty restored 47% of the lost height. Cement leakage occurred at six levels (8.6%).SF-36 scores for Bodily Pain 11.6-58.7, (P = 0.0001) and Physical Function 11.7-47.4, (P = 0.002) were among those that showed significant improvement.


CONCLUSIONS
The inflatable bone tamp was efficacious in the treatment of osteoporotic vertebral compression fractures. Kyphoplasty is associated with early clinical improvement of pain and function as well as restoration of vertebral body height in the treatment of painful osteoporotic compression fractures.
Ontology-based data integration in EPNet: Production and distribution of food during the Roman Empire

Semantic technologies are rapidly changing the historical research. Over the last decades, an immense amount of new quantifiable data have been accumulated, and made available in interchangeable formats, in social sciences and humanities, opening up new possibilities for solving old questions and posing new ones. This paper introduces a framework that eases the access of scholars to historical and cultural data about food production and commercial trade system during the Roman Empire, distributed across different data sources. The proposed approach relies on the Ontology-Based Data Access (OBDA) paradigm, where the different datasets are virtually integrated by a conceptual layer (an ontology) that provides to the user a clear point of access and a unified and unambiguous conceptual view. & 2016 Published by Elsevier Ltd. 2 http://www.europeana.eu. 3 http://www.kulttuurisampo.fi. 4 http://www.cs.vu.nl/STITCH. 5 http://e-culture.multimedian.nl. 6 http://chip.win.tue.nl. 7 http://http://www.eagle-network.eu. 8 http://www.cidoc-crm.org.
Compliance of pharmacological treatment for non-ST-elevation acute coronary syndromes with contemporary guidelines: influence on outcomes.

BACKGROUND
Although the proven efficacy of evidence-based therapy in patients with cardiovascular diseases, the recommendations are not always instituted. We aimed to analyse the compliance of non-ST-elevation acute coronary syndrome (NSTE-ACS) patients with treatment guidelines and to assess the impact of these measures in hospital death during the index hospitalization.


POPULATION AND METHODS
All consecutive patients (pts) included in the Portuguese Registry on Acute Coronary Syndromes (ProACS) between January 1, 2002 and August 31, 2011 were analysed. Compliance with Guidelines for the management of NSTE-ACS was evaluated with a 6-point therapeutic score (ThSc), comprising the treatment with: aspirin, clopidogrel, heparin, beta-blocker, angiotensin-converting enzyme inhibitor and statin. One point was assigned for each drug prescribed and zero if not given. The total therapeutic compliance was defined as ThSc =6 points.


RESULTS
The final analysis comprised 14,276 pts (67.1% male; mean age 67.6±12.3 years), most of them admitted with non-ST elevation myocardial infarction (77.4%). The mean value of ThSc was 4.9±1.1 and total compliance occurred in 36.7% pts. Centres with percutaneous coronary intervention (PCI) capacity had a statistically significant higher ThSc (5.0±1.0 vs. 4.8±1.1, P<0.001) and were associated with higher total compliance [OR 1.53, 95% confidence intervals (CI), 1.42-1.65, P<0.001]. In-hospital mortality was 2.4% (354 deaths). Compared to pts who died, the survivors had a higher ThSc (4.9±1.1 vs. 4.2±1.3, P<0.001) and this score was independently associated with lower risk of in-hospital mortality (OR 0.70, 95% CI, 0.64-0.77, P<0.001). Receiver operating characteristics curve analysis showed a good accuracy of ThSc for the occurrence of in-hospital mortality with the area under the curve (AUC) 0.82 (95% CI, 0.80-0.84, P<0.001), sensitivity 71.6% and specificity 78.0%. Age, peripheral artery disease, Killip-Kimball class >I, electrocardiogram (ECG) with ST-segment depression and positive troponin were other independent predictors of in-hospital mortality.


CONCLUSIONS
In the present study, patients with NSTE-ACS who received medications recommended by guidelines had better in-hospital outcomes. These findings highlight the need to clarify the clinical recommendations and to develop approaches for quality improvement in this subset of patients.
Contamination of commonly consumed raw vegetables with soil transmitted helminth eggs in Mazandaran province, northern Iran.

Soil-transmitted helminth (STH) infections are responsible for significant burden of morbidity and mortality worldwide. Consumption of raw vegetables without proper washing is one of the major routes of such infections. We evaluate the prevalence of STH contamination in commonly used vegetables in Mazandaran province, northern Iran. A total of 772 fresh raw vegetables were obtained from retail markets. Each sample was divided into two groups. One group was used as the unwashed sample and the second group was washed with standard washing procedures. Then, samples were examined for helminth eggs by using standard methods. Data analysis was performed using SPSS20. The overall prevalence of STHs was 14.89% (115/772). The rate of STH contamination was significantly higher in warm seasons (20.5%, 79/386) than in cold seasons (9.32%, 36/386) among the unwashed vegetables (OR=2.50; CI 95%=1.64-3.8; P<0.001). No parasites were observed in standard washed samples (OR=271.40; CI 95%=16.84-4373.64; P<0.001). Prevalence of STH contamination was significantly higher in leafy vegetables than root vegetables (OR=1.67; CI 95%=1.09-2.55; P<0.05). The prevalence of STHs species in all the vegetables were as follows: Ascaris lumbricoides (3.36%), Trichuris trichiura (2.2%), hookworms (2.9%), Toxocara spp. (1.68%), Trichostrongylus spp. (1.55), Taenia sp. (0.9%) and Hymenolepis nana (2.2%). The results of the present study emphasized that vegetables are potential risk factor for transmission of helminth infection to human in northern Iran. It is necessary that health authorities trained the consumers to proper and standard washing of vegetables before consumption.
An Interactive Game Approach for Improving Students’ Learning Performance in Multi-Touch Game-Based Learning

This study, based on Taiwanese geographical concepts, develops a multi-touch interactive jigsaw puzzle (MIJP) to assist primary school students in solving geographical puzzles. The MIJP, which has multi-touch operating characteristics and provides two kinds of scaffolding tools, each with a different level of difficulty, can assist students in solving problems in the games and prevent them from feeling stuck and frustrated. In addition, it explores the influence of the interactive game approach (three levels of difficulty) on learning performance and satisfaction. The results indicated that the learning performance of each group, significantly improved after the experiment. In particular, moderate gaming difficulty led to the best learning performance for learners. A comparison of learners who did not use scaffolding to solve problems and those who did shows the level of the zone of proximal development (ZPD). Moreover, the analysis of satisfaction evaluations by learners with/without scaffolding showed there were statistically significant differences in the measures of learning satisfaction. Finally, this study revealed that the students tended to be over-reliant on the scaffolding tools during the game, which prevented them from internalizing knowledge through the interactive learning process.
Association of emergency department opioid initiation with recurrent opioid use.

STUDY OBJECTIVE
Acute pain complaints are commonly treated in the emergency department (ED). Short courses of opioids are presumed to be safe for acute pain; however, the risk of recurrent opioid use after receipt of an ED opioid prescription is unknown. We describe the risk of recurrent opioid use in patients receiving an opioid prescription from the ED for an acute painful condition.


METHODS
This is a retrospective cohort study of all patients discharged from an urban academic ED with an acute painful condition during a 5-month period. Clinical information was linked to data from Colorado's prescription drug monitoring program. We compared opioid-naive patients (no opioid prescription during the year before the visit) who filled an opioid prescription or received a prescription but did not fill it to those who did not receive a prescription. The primary outcome was the rate of recurrent opioid use, defined as filling an opioid prescription within 60 days before or after the first anniversary of the ED visit.


RESULTS
Four thousand eight hundred one patients were treated for an acute painful condition; of these, 52% were opioid naive and 48% received an opioid prescription. Among all opioid-naive patients, 775 (31%) received and filled an opioid prescription, and 299 (12%) went on to recurrent use. For opioid-naive patients who filled a prescription compared with those who did not receive a prescription, the adjusted odds ratio for recurrent use was 1.8 (95% confidence interval 1.3 to 2.3). For opioid-naive patients who received a prescription but did not fill it compared with those who did not receive a prescription, the adjusted odds ratio for recurrent use was 0.8 (95% confidence interval 0.5 to 1.3).


CONCLUSION
Opioid-naive ED patients prescribed opioids for acute pain are at increased risk for additional opioid use at 1 year.
MathFind: a math-aware search engine

1. SYSTEM OVERVIEW Researchers working in technical disciplines wishing to search for information related to a particular mathematical expression cannot effectively do so with a text-based search engine unless they know appropriate text keywords. To overcome this difficulty, we demonstrate a math-aware search engine, which extends the capability of existing text search engines to search mathematical content.
Aggravated fragmentation : A case study of SME behaviour in two emerging heritage tourism regions

This paper investigates the behaviour of small and medium sized enterprises (SMEs) within the heritage tourism supply chain (HTSC), in two emerging heritage regions. SMEs are conceptualised as implementers, working within the constraints of government level tourism structures and the heritage tourism supply chain. The research employs a case study approach, focusing on two emerging regions in Northern Ireland. In-depth interviews were carried out with small business owners and community associations operating within the regions. The research identifies SME dissatisfaction with the supply chain and the processes in place for the delivery of the tourism product. To overcome the perceived inadequacies of the heritage tourism supply chain SMEs engage in entrepreneurial behaviour by attempting to deliver specific products and services to meet the need of tourists. The challenge for tourism organisations is how they can integrate the entrepreneurial, innovative activities of SMEs into the heritage tourism system. © 2016 Published by Elsevier Ltd.
Lowness Properties of Reals and Hyper-Immunity

Abstract Ambos-Spies and Kucera [1, Problem 4.5] asked if there is a non-computable set A which is low for the computably random reals. We show that no such A is of hyper-immune degree. Thus, each g ≤ T A is dominated by a computable function. Ambos-Spies and Kucera [1, problem 4.8] also asked if every S-low set is S 0 -low. We give a partial solution to this problem, showing that no S -low set is of hyper-immune degree.
Review of failures and condition monitoring in wind turbine generators

Increasing wind power generation quantity in power systems needs obviously reliable operation. Therefore, accurate condition monitoring and fault diagnosis are almost mandatory. This paper aims to report recent works on condition monitoring and fault diagnosis for wind turbine generators. Wind turbines are subjected to different sort of failures, thus before stating condition monitoring and fault diagnosis methods it is necessary to identify what kind of failures can be found in the real world. As a result, the gearbox is one of the most critical components of the wind turbine in which failures could stop generation for a long time. Recently, several condition monitoring and fault diagnosis techniques have been introduced in order to minimize downtime and maintenance cost while increasing energy availability and life time service of the wind farms. Vibration sensors have been used for long time in wind turbine condition monitoring systems to collect data of the generator health. Actually, using such sensors is expensive, difficult to install and sometimes impossible to be implemented in already installed wind turbines. Therefore, researchers have been focused on using electrical signature analysis from sensors in order to detect wind turbines faults and generator health in a cheap, easy to install and accessible way.
Purchasing Consortia and Electronic Markets - A Procurement Direction in Integrated Supply Chain Management

structured along the lines of: background, aim, method, results, conclusion – 150 – 200 words): In supply chain management literature, there has been little empirical research investigation on purchasing consortium issues focusing on a detailed analysis of information and communication (ICT) based procurement strategies. Based on the exploration of academic literature and two surveys among purchasing organisations as well as e-Marketplaces / procurement service providers (PSPs) in the automotive and electronics industry sectors, the research methodology follows a positivistic approach in order to assess the overall statement: ‘Effective participation in electronic purchasing consortia (EPC) can have the potential to enhance competitive advantage. Implementation therefore requires a clear and detailed understanding of the major process structures and drivers, based upon the technology-organisation-environment framework.’ Key factors and structures that affect the adoption and diffusion of EPC and the performance impact of adoption are investigated. The empirically derived model for EPC can be a valuable starting point to EPC research. 242845-text.native.1300707444.doc Page 1
Fast food for family meals: relationships with parent and adolescent food intake, home food availability and weight status.

OBJECTIVE
The purpose of the present study was to examine the prevalence of fast-food purchases for family meals and the associations with sociodemographic variables, dietary intake, home food environment, and weight status in adolescents and their parents.


DESIGN
This study is a cross-sectional evaluation of parent interviews and adolescent surveys from Project EAT (Eating Among Teens).


SUBJECTS
Subjects included 902 middle-school and high-school adolescents (53% female, 47% male) and their parents (89% female, 11% male). The adolescent population was ethnically diverse: 29% white, 24% black, 21% Asian American, 14% Hispanic and 12% other.


RESULTS
Results showed that parents who reported purchasing fast food for family meals at least 3 times per week were significantly more likely than parents who reported purchasing fewer fast-food family meals to report the availability of soda pop and chips in the home. Adolescents in homes with fewer than 3 fast-food family meals per week were significantly more likely than adolescents in homes with more fast-food family meals to report having vegetables and milk served with meals at home. Fast-food purchases for family meals were positively associated with the intake of fast foods and salty snack foods for both parents and adolescents; and weight status among parents. Fast-food purchases for family meals were negatively associated with parental vegetable intake.


CONCLUSIONS
Fast-food purchases may be helpful for busy families, but families need to be educated on the effects of fast food for family meals and how to choose healthier, convenient family meals.
Quasi-metric relativity

This is a survey of a new type of relativistic space-time framework; the "quasi-metric" framework. See the abstract of gr-qc/0111110 to get some idea of its geometrical basis. A theory of gravity consistent with the quasi-metric framework is presented. It is not yet clear whether or not this theory is viable, but in its non-metric sector it makes successful predictions from first principles where metric theories fail.
One Way Hash Functions and DES

One way hash functions are a major tool in cryptography. DES is the best known and most widely used encryption function in the commercial world today. Generating a one-way hash function which is secure if DES is a “good” block cipher would therefore be useful. We show three such functions which are secure if DES is a good random block cipher.
A theory of sequential reciprocity

Many experimental studies indicate that people are motivated by reciprocity. Rabin [Amer. Rev. 83 (1993) 1281] develops techniques for incorporating such concerns into game theo economics. His theory is developed for normal form games, and he abstracts from information the sequential structure of a strategic situation. We develop a theory of reciprocity for ext games in which the sequential structure of a strategic situation is made explicit, and propose solution concept—sequential reciprocity equilibrium—for which we prove an equilibrium exis result. The model is applied in several examples, and it is shown that it captures very well the in meaning of reciprocity as well as certain qualitative features of experimental evidence.  2003 Elsevier Inc.

Combining Challenge-Based Learning and Scrum Framework for Mobile Application Development

The market for mobile applications has been growing dramatically, as has the complexity of the applications and the speed of the development process. These changes require a rethinking of the development process and of how developers are trained. In order to better prepare faculty and students for the emerging mobile application market, this study presents a new learning and software development framework that combines Agile methodologies with the Challenge-Based Learning (CBL) framework. CBL provides a student-centered learning framework that mirrors the modern workplace. Agile methodologies address the changing landscape of mobile development environments. A combination of the CBL learning framework and Agile methodologies can better prepare students for the development market. This paper presents an empirical study applying CBL and Scrum in a mobile application development course evaluated through a series of post surveys. The results indicate that a teaching and learning environment based on practical experience combining the CBL framework with the Scrum process is an eective model to promptly teach undergraduates how to be successful mobile application developers.
