The study aimed to assess the efficacy of erbium laser technology compared with traditional drilling for caries removal. A systematic search was conducted through Medline via PubMed, Embase, Cochrane databases, CNKI till December 2016. Randomised controlled trials, quasi-randomized controlled trials, or controlled clinical trials with data comparing the efficacy of erbium laser technology versus traditional drilling for caries removal were included. Fourteen studies were selected in our meta-analysis. Erbium laser technology showed an increased time when removing caries compared with drilling (mean difference: 3.48, 95% confidence interval: 1.90-5.06, P < .0001). However, erbium laser technology reduced the requirement for local anesthesia (risk ratio: 0.28, 95% confidence interval: 0.13-0.62, P = .002). Erbium laser technology was also not significantly different to traditional drilling with regard to restoration loss, pulpal vitality, and postoperative sensitivity. Erbium laser technology showed an increased time for cavity preparation compared with traditional drilling. However, erbium laser technology reduced the requirement for local anesthesia. There was no significant difference between erbium laser technology and traditional drilling regarding restoration loss, pulpal vitality, and postoperative sensitivity. Copyright © 2017 Elsevier Inc.

A study of the effects of an experimental spiral physics curriculum taught to sixth grade girls and boys

NASA Astrophysics Data System (ADS)

Davis, Edith G.

The pilot study compared the effectiveness of using an experimental spiral physics curriculum to a traditional linear physics curriculum for sixth through eighth grades. The study also surveyed students' parents and principals about students' academic history and background as well as identified resilient children's attributes for academic success. The pilot study was used to help validate the testing instrument as well as help refine the complete study. The purpose of the complete study was to compare the effectiveness of using an experimental spiral physics curriculum and a traditional linear curriculum with sixth graders only; seventh and eighth graders were dropped in the complete study. The study also surveyed students' parents, teachers, and principals about students' academic history and background as well as identified resilient children's attributes for academic success. Both the experimental spiral physics curriculum and the traditional linear physics curriculum increased physics achievement; however, there was no statistically significant difference in effectiveness of teaching experimental spiral physics curriculum in the aggregated sixth grade group compared to the traditional linear physics curriculum. It is important to note that the majority of the subgroups studied did show statistically significant differences in effectiveness for the experimental spiral physics curriculum compared to the traditional linear physics curriculum. The Grounded Theory analysis of resilient student characteristics resulted in categories for future studies including the empathy factor ("E" factor), the tenacity factor ("T" factor), the relational factor ("R" factor), and the spiritual factor ("S" factor).

Recently, a traditional remedy (Joshanda) has been replaced largely by modern ready-to-use dosage forms, which have not been compared to the original remedy. Therefore, the present study aimed to compare a number of modern dosage forms with traditional remedy. Seven brands, 3 batches each, were compared with a Lab-made formulation with reference to analytical (proximate analyses, spectroscopic and chromatographic metabolomes) and pharmacological profiles (anti-inflammatory and antibacterial activities). Chemical and pharmacological differences were found between Lab-made Joshanda and modern dosage forms. Such variations were also found within the brands and batches of modern formulations (p < 0.05). The Lab-made Joshanda showed significantly higher pharmacological activities as compared to modern brands (p ). The results of the present study indicate that modern dosage forms are unstandardised and less effective than the traditional remedy. Characteristic profiles obtained from Lab-made Joshanda may be used as reference to produce comparable dosage forms.

Chapa, Hector O; Venegas, Gonzalo

2015-01-01

To compare vaginoscopic hysteroscopic sterilization with traditional hysteroscopic approach for differences in pain, bilateral microinsert placement rates, and procedure time. We performed a prospective, randomized, single-blinded study of hysteroscopic sterilization using the Essure System. The study setting was an inner city ObGyn clinic. Ninety patients were randomized to either vaginoscopy or traditional approach. The traditional approach was speculum insertion, paracervical analgesia, and tenaculum. All procedures were done with a 5 mm, 30 degree rigid hysteroscope. Main outcome measures were pain scores (10-point visual analog scale), bilateral placement rates, and procedure times. Vaginoscopy was successful in 42/45 patients (93%). There was no statistically significant difference in pain-scores for microinsert placement between the groups (p = 0.71). First attempt, bilateral microinsert placement rate was 95% (40/42) with vaginoscopy and 95% (43/45) with traditional (p = 0.89). Time for treatment completion was 16 minutes (mean) (range, 13-21) in the traditional group versus vaginoscopy time of 9 minutes (mean) (range, 7-11) (p = 0.03). Hysteroscopic sterilization via vaginoscopy is feasible with bilateral microinsert rates comparable to those of traditional hysteroscopy. Vaginoscopy is associated with less overall discomfort and is faster to perform.

Herbal medicines formulated as oils were believed to possess more powerful effects than their original plants in Iranian Traditional Medicine (ITM). One of the popular oils suggested for treatment of various indications was ginger oil. In the present study, to suggest a more convenient method of oil preparation (compared to the traditional method), ginger oil has been prepared according to both the traditional and conventional maceration methods and the volatile oil constituents have been compared. Ginger oil was obtained in sesame oil according to both the traditional way and the conventional (maceration) methods. The volatile oil of dried ginger and both oils were obtained by hydro-distillation and analyzed by gas chromatography/mass spectroscopy. Fifty five, fifty nine and fifty one components consisting 94 %, 94 % and 98 % of the total compounds were identified in the volatile oil of ginger, traditional and conventional oils, respectively. The most dominant compounds of the traditional and conventional oils were almost similar; however they were different from ginger essential oil which has also been to possess limited amounts of anti-inflammatory components. It was concluded that ginger oil could be prepared through maceration method and used for indications mentioned in ITM.

2010-10-01

The availability and quality of irrigation water have become a serious concern because of global climate change and an increased competition for water by industry, domestic users and the environment. Therefore, exploring environmentally friendly water-saving irrigation strategies is essential for achieving food and environmental security. In northern Ethiopia, where traditional furrow irrigation is widely practiced, water mismanagement and its undesirable environmental impact are rampant. A 2-year field study was undertaken to compare the traditional irrigation management with surge and deficit irrigation practices on a Vertisol plot. Results have shown that surge and deficit irrigation practices increase water productivity by 62% and 58%, respectively, when compared to traditional management. The study also found out that these practices reduce the adverse environmental impacts (waterlogging and salinity) of traditional management by minimizing deep percolation and tail water losses. Total irrigation depth was reduced by 12% (for surge) and 27% (for deficit) when compared to traditional management. Based on the results, the study concluded that surge and deficit irrigation technologies not only improve water productivity but also enhance environmental sustainability.

To evaluate and compare students' perceptions about teaching and learning, knowledge and skills, outcomes of course materials and their satisfaction in traditional Lecture Based learning versus Problem-Based Learning curricula in two different medical schools. The comparative cross-sectional questionnaire-based study was conducted in the Department of Physiology, College of Medicine, King Saud University, Riyadh, Saudi Arabia, from July 2009 to January 2011. Two different undergraduate medical schools were selected; one followed the traditional curriculum, while the other followed the problem-based learning curriculum. Two equal groups of first year medical students were selected. They were taught in respiratory physiology and lung function lab according to their curriculum for a period of two weeks. At the completion of the study period, a five-point Likert scale was used to assess students' perceptions on satisfaction, academic environment, teaching and learning, knowledge and skills and outcomes of course materials about effectiveness of problem-based learning compared to traditional methods. SPSS 19 was used for statistical analysis. Students used to problem-based learning curriculum obtained marginally higher scores in their perceptions (24.10 +/- 3.63) compared to ones following the traditional curriculum (22.67 +/- 3.74). However, the difference in perceptions did not achieve a level of statistical significance. Students following problem-based learning curriculum have more positive perceptions on teaching and learning, knowledge and skills, outcomes of their course materials and satisfaction compared to the students belonging to the traditional style of medical school. However, the difference between the two groups was not statistically significant.

Ginger drink is one of the traditional beverage that became one of the products of interest by consumers in Indonesia. This drink is believed to have excellent properties for the health of the body. In this study, we have compared the moisture content, ash content, metal content and the identified compound of product which processed with traditional technique and using an evaporator machine. The results show that both of products fulfilled some parameters of the Indonesian National Standard for the traditional powdered drink. GC-MS analysis data showed the identified compound of both product. The major of hydrocarbon groups that influenced the flavor such as zingiberene, camphene, beta-phelladrine, beta-sesquepelladrine, curcumene, and beta-bisabolene were found higher in ginger drink powder treated with a machine than those processed traditionally.

Alternative and traditional assessments: Their comparative impact on students' attitudes and science learning outcomes. An exploratory study

NASA Astrophysics Data System (ADS)

Century, Daisy Nelson

This probing study focused on alternative and traditional assessments, their comparative impacts on students' attitudes and science learning outcomes. Four basic questions were asked: What type of science learning stemming from the instruction can best be assessed by the use of traditional paper-and pencil test? What type of science learning stemming from the instruction can best be assessed by the use of alternative assessment? What are the differences in the types of learning outcomes that can be assessed by the use of paper-pencil test and alternative assessment test? Is there a difference in students' attitude towards learning science when assessment of outcomes is by alternative assessment means compared to traditional means compared to traditional means? A mixed methodology involving quantitative and qualitative techniques was utilized. However, the study was essentially a case study. Quantitative data analysis included content achievement and attitude results, to which non-parametric statistics were applied. Analysis of qualitative data was done as a case study utilizing pre-set protocols resulting in a narrative summary style of report. These outcomes were combined in order to produce conclusions. This study revealed that the traditional method yielded more concrete cognitive content learning than did the alternative assessment. The alternative assessment yielded more psychomotor, cooperative learning and critical thinking skills. In both the alternative and the traditional methods the student's attitudes toward science were positive. There was no significant differences favoring either group. The quantitative findings of no statistically significant differences suggest that at a minimum there is no loss in the use of alternative assessment methods, in this instance, performance testing. Adding the results from the qualitative analysis to this suggests (1) that class groups were more satisfied when alternative methods were employed, and (2) that the two assessment methodologies are complementary to each other, and thus should probably be used together to produce maximum benefit.

Blended Learning Versus Traditional Lecture in Introductory Nursing Pathophysiology Courses.

PubMed

Blissitt, Andrea Marie

2016-04-01

Currently, many undergraduate nursing courses use blended-learning course formats with success; however, little evidence exists that supports the use of blended formats in introductory pathophysiology courses. The purpose of this study was to compare the scores on pre- and posttests and course satisfaction between traditional and blended course formats in an introductory nursing pathophysiology course. This study used a quantitative, quasi-experimental, nonrandomized control group, pretest-posttest design. Analysis of covariance compared pre- and posttest scores, and a t test for independent samples compared students' reported course satisfaction of the traditional and blended course formats. Results indicated that the differences in posttest scores were not statistically significant between groups. Students in the traditional group reported statistically significantly higher satisfaction ratings than students in the blended group. The results of this study support the need for further research of using blended learning in introductory pathophysiology courses in undergraduate baccalaureate nursing programs. Further investigation into how satisfaction is affected by course formats is needed. Copyright 2016, SLACK Incorporated.

The objective of this study was to compare leadership and academic performance among students admitted by traditional pathways vs. a dual acceptance program (DAP). A list of students admitted to the Midwestern University Chicago College of Pharmacy (MWUCCP) DAP was cross-checked with students elected to serve in leadership positions and students on the MWUCCP Dean's List for their first professional year from 2010 to 2015. The proportion of students serving in leadership positions and those on the Dean's List were compared to students that matriculated via the traditional route. In total, 1069 students were analyzed (n = 937 traditional; n = 132 DAP). DAP students were more likely to have an elected leadership role (n = 61, 46.2% vs. n = 314, 33.5%, p < 0.01) and achieve Dean's List for their first professional year (n = 64, 48.5% vs. n = 292, 31.2%, p < 0.01) compared to traditional students. DAP students were more likely to hold an elected leadership position than traditional students. Further study of DAP student motivation is needed to potentially assist in the success of other students. Copyright © 2017 Elsevier Inc. All rights reserved.

Information on the profitability and productivity of box hives is important to encourage beekeepers to adopt the technology. However, comparative analysis of profitability and productivity of box and traditional hives is not adequately available. The study was carried out on 182 beekeepers using cross sectional survey and employing a random sampling technique. The data were analyzed using descriptive statistics, analysis of variance (ANOVA), the Cobb-Douglas (CD) production function and partial budgeting. The CD production function revealed that supplementary bee feeds, labor and medication were statistically significant for both box and traditional hives. Generally, labor for bee management, supplementary feeding, and medication led to productivity differences of approximately 42.83%, 7.52%, and 5.34%, respectively, between box and traditional hives. The study indicated that productivity of box hives were 72% higher than traditional hives. The average net incomes of beekeepers using box and traditional hives were 33,699.7 SR/annum and 16,461.4 SR/annum respectively. The incremental net benefit of box hives over traditional hives was nearly double. Our study results clearly showed the importance of adoption of box hives for better productivity of the beekeeping subsector.

We explored factors associated with traditional maternity/herbal homes (TMHs) run by traditional birth attendants (TBAs) compared with hospital or home delivery in Lagos, Nigeria, and found that infants delivered at TMHs were less likely to have severe hyperbilirubinemia compared with infants delivered in hospitals or residential homes. These infants were also less likely to be preterm compared with those delivered in hospitals or undernourished compared with infants delivered in residential homes. We concluded that infants delivered at TMHs who survive are unlikely to be at greater risks of some adverse perinatal outcomes than those delivered in hospitals or family homes.

Introduction There is a demand for more attractive and efficient training programmes in postgraduate health care training. This retrospective study aims to show the effectiveness of a blended versus traditional face-to-face training design. For nurses in postgraduate Acute and Intensive Care training, the effectiveness of a blended course design was compared with a traditional design. Methods In a first pilot study 57 students took a traditional course (2-h lecture and 2-h workshop) and 46 students took a blended course (2-h lecture and 2-h online self-study material). Test results were compared for both groups. After positive results in the pilot study, the design was replicated for the complete programme in Acute and Intensive Care. Now 16 students followed the traditional programme (11 days face-to-face education) and 31 students did the blended programme (7 days face-to-face and 40 h online self-study). An evaluation was done after the pilot and course costs were calculated. Results Results show that the traditional and blended groups were similar regarding the main characteristics and did not differ in learning results for both the pilot and the complete programme. Student evaluations of both designs were positive; however, the blended group were more confident that they had achieved the learning objectives. Training costs were reduced substantially. Conclusion The blended training design offers an effective and attractive training solution, leading to a significant reduction in costs.

López Martín, M Beatriz; Erice Calvo-Sotelo, Alejo

To compare presurgical hand hygiene with hydroalcoholic solution following the WHO protocol with traditional presurgical hand hygiene. Cultures of the hands of surgeons and surgical nurses were performed before and after presurgical hand hygiene and after removing gloves at the end of surgery. Cultures were done in 2different days: the first day after traditional presurgical hand hygiene, and the second day after presurgical hand hygiene with hydroalcoholic solution following the WHO protocol. The duration of the traditional hand hygiene was measured and compared with the duration (3min) of the WHO protocol. The cost of the products used in the traditional technique was compared with the cost of the hydroalcoholic solution used. The variability of the traditional technique was determined by observation. Following presurgical hand hygiene with hydroalcoholic solution, colony-forming units (CFU) were detected in 5 (7.3%) subjects, whereas after traditional presurgical hand hygiene CFU were detected in 14 subjects (20.5%) (p < 0.05). After glove removal, the numbers of CFU were similar. The time employed in hand hygiene with hydroalcoholic solution (3min) was inferior to the time employed in the traditional technique (p < 0.05), its cost was less than half, and there was no variability. Compared with other techniques, presurgical hand hygiene with hydroalcoholic solution significantly decreases CFU, has similar latency time, a lower cost, and saves time.

Zhao, Yan; Qu, Hui-Hua; Wang, Qing-Guo

2013-09-01

Study on pharmacodynamic material basis of traditional Chinese medicines is one of the key issues for the modernization of traditional Chinese medicine. Having introduced the monoclonal antibody technology into the study on pharmacodynamic material basis of traditional Chinese medicines, the author prepared the immunoaffinity chromatography column by using monoclonal antibodies in active components of traditional Chinese medicines, so as to selectively knock out the component from herbs or traditional Chinese medicine compounds, while preserving all of the other components and keeping their amount and ratio unchanged. A comparative study on pharmacokinetics and pharmacodynamics was made to explicitly reveal the correlation between the component and the main purpose of traditional Chinese medicines and compounds. The analysis on pharmacodynamic material basis of traditional Chinese medicines by using specific knockout technology with monoclonal antibodies is a new method for study pharmacodynamic material basis in line with the characteristics of traditional Chinese medicines. Its results can not only help study material basis from a new perspective, but also help find the modern scientific significance in single herb or among compounds of traditional Chinese medicines.

Objective to determine the effectiveness of HIT on cardiopulmonary fitness and body composition in adults with obesity compared to traditional (high volume continuous) exercise. Methods A systematic search of the main health science databases was conducted for randomized controlled trials comparing HIT with traditional forms of exercise in people with obesity. Eighteen studies were included in the meta‐analysis. The (unstandardized) mean difference of each outcome parameters was calculated and pooled with the random effects model. Results HIT resulted in greater improvement of cardiopulmonary fitness (VO2max) (MD 1.83, 95% CI 0.70, 2.96, p<0.005; I2=31%) and a greater reduction of %body fat (MD ‐1.69, 95% CI ‐3.10, ‐0.27, p=0.02, I2=30%) compared to traditional exercise. Overall effect for BMI was not different between HIT and traditional exercise. Conclusion Training at high intensity is superior to improve cardiopulmonary fitness and to reduce %body fat in adults with obesity compared to traditional exercise. Future studies are needed to design specific HIT programs for the obese with regard to optimal effect and long‐term adherence. PMID:29071102

Abdelaal, Mohammed Mahmoud; Aboelatta, Yasser Abdallah

2014-08-01

Laser-assisted liposuction has been associated with reduced blood loss. However, this clinical finding has not been evaluated objectively. In this study, the authors objectively estimated the blood loss volume associated with laser lipolysis vs traditional liposuction in various anatomic regions. In this prospective study, 56 patients underwent equal amounts of traditional and laser-assisted liposuction at 2 contralateral anatomic sites. Blood loss volumes were calculated from the lipoaspirates by measuring hemoglobin and red blood cell content. The data were analyzed statistically with repeated-measures analysis of variance and the Mann-Whitney U test. Laser lipolysis can reduce blood loss by more than 50% compared with traditional liposuction. Laser lipolysis resulted in significant reductions in mean blood loss volumes in the abdomen, flanks, back, and breast. The authors provide objective evidence that laser lipolysis significantly reduces blood loss compared with traditional liposuction. 3. © 2014 The American Society for Aesthetic Plastic Surgery, Inc.

In Australia trampolines contribute one quarter of all childhood play equipment injuries. The objective of this study was to gather and evaluate injury data from a non-traditional, 'soft-edged', consumer trampoline, where the design aimed to minimise injuries from the equipment and from falling off. The manufacturer of the non-traditional trampoline provided the University of Technology Sydney with their Australian customer database. The study involved surveys in Queensland and New South Wales, between May 2007 and March 2010. Initially injury data was gathered by a phone interview pilot study, then in the full study, through an email survey. The 3817 respondents were the carers of child users of the 'soft-edge' trampolines. Responses were compared with Australian and US emergency department data. In both countries the proportion of injuries caused by the equipment and falling off was compared with the proportion caused by the jumpers to themselves or each other. The comparisons showed a significantly lower proportion resulted from falling-off or hitting the equipment for this design when compared to traditional trampolines, both in Australia and the US. This research concludes that equipment-induced and falling-off injuries, the more severe injuries on traditional trampolines, can be significantly reduced with appropriate trampoline design.

The present study was conducted to investigate whether the calming effect induced by viewing traditional Chinese landscape paintings would make disengagement from that mental state more difficult, as measured by performance on a cognitive control task. In Experiment 1 we examined the subjective experience of viewing traditional Chinese landscape paintings vs. realistic oil landscape paintings in a behavioral study. Our results confirmed that, as predicted, traditional Chinese landscape paintings induce greater levels of relaxation and mind wandering and lower levels of object-oriented absorption and recognition, compared to realistic oil landscape paintings. In Experiment 2 we used functional Magnetic Resonance Imaging to explore the behavioral and neural effects of viewing traditional Chinese landscape paintings on a task requiring cognitive control (i.e., the flanker task)-administered immediately following exposure to paintings. Contrary to our prediction, the behavioral data demonstrated that compared to realistic oil landscape paintings, exposure to traditional Chinese landscape paintings had no effect on performance on the flanker task. However, the neural data demonstrated an interaction effect such that there was greater activation in the inferior parietal cortex and the superior frontal gyrus on incongruent compared with congruent flanker trials when participants switched from viewing traditional Chinese landscape paintings to the flanker task than when they switched from realistic oil landscape paintings. These results suggest that switching from traditional Chinese landscape paintings placed greater demands on the brain's attention and working memory networks during the flanker task than did switching from realistic oil landscape paintings.

Traditional cigarette advertising has existed in the US for over 200 years. Studies suggest that advertising has an impact on the initiation and maintenance of smoking behaviors. In recent years, electronic cigarettes (e-cigarettes) emerged on the market as an alternative to the traditional tobacco cigarette. The purpose of this study was to describe advertisements in popular US magazines marketed to women for cigarettes and e-cigarettes. This study involved analyzing 99 issues of 14 popular US magazines marketed to women. Compared to advertisements for traditional cigarettes, advertisements for e-cigarettes were more often found in magazines geared toward the 31-40-year-old audience (76.5% vs. 53.1%, P = 0.011) whereas traditional cigarette advertisements were nearly equally distributed among women 31-40 and ≥40 years. More than three-quarters of the e-cigarette advertisements presented in magazines aimed at the higher median income households compared to a balanced distribution by income for traditional cigarettes (P = 0.033). Future studies should focus on specific marketing tactics used to promote e-cigarette use as this product increases in popularity, especially among young women smokers.

2015-06-01

Despite the benefits of the objective structured assessment of technical skills (OSATS) and it appropriateness for evaluating clinical abilities of nursing students , few studies are available on the application of this method in nursing education. The purpose of this study was to compare the effect of using OSATS and traditional methods on the students' learning. We also aimed to signify students' views about these two methods and their views about the scores they received in these methods in a medical emergency course. A quasi-experimental study was performed on 45 first semester students in nursing and medical emergencies passing a course on fundamentals of practice. The students were selected by a census method and evaluated by both the OSATS and traditional methods. Data collection was performed using checklists prepared based on the 'text book of nursing procedures checklists' published by Iranian nursing organization and a questionnaire containing learning rate and students' estimation of their received scores. Descriptive statistics as well as paired t-test and independent samples t-test were used in data analysis. The mean of students' score in OSATS was significantly higher than their mean score in traditional method (P = 0.01). Moreover, the mean of self-evaluation score after the traditional method was relatively the same as the score the students received in the exam. However, the mean of self-evaluation score after the OSATS was relatively lower than the scores the students received in the OSATS exam. Most students believed that OSATS can evaluate a wide range of students' knowledge and skills compared to traditional method. Results of this study indicated the better effect of OSATS on learning and its relative superiority in precise assessment of clinical skills compared with the traditional evaluation method. Therefore, we recommend using this method in evaluation of students in practical courses.

The flipped classroom allows for more class time devoted to critical thinking.

PubMed

DeRuisseau, Lara R

2016-12-01

The flipped classroom was utilized in a two-semester, high-content science course that enrolled between 50 and 80 students at a small liberal arts college. With the flipped model, students watched ~20-min lectures 2 days/wk outside of class. These videos were recorded via screen capture and included a detailed note outline, PowerPoint slides, and review questions. The traditional format included the same materials, except that lectures were delivered in class each week and spanned the entire period. During the flipped course, the instructor reviewed common misconceptions and asked questions requiring higher-order thinking, and five graded case studies were performed each semester. To determine whether assessments included additional higher-order thinking skills in the flipped vs. traditional model, questions across course formats were compared via Blooms Taxonomy. Application-level questions that required prediction of an outcome in a new scenario comprised 38 ± 3 vs. 12 ± 1% of summative assessment questions (<0.01): flipped vs. traditional. Final letter grades in both formats of the course were compared with major GPA. Students in the flipped model performed better than their GPA predicted, as 85.5% earned a higher grade (vs. 42.2% in the traditional classroom) compared with their major GPA. These data demonstrate that assessments transitioned to more application-level compared with factual knowledge-based questions with this particular flipped model, and students performed better in their final letter grade compared with the traditional lecture format. Although the benefits to a flipped classroom are highlighted, student evaluations did suffer. More detailed studies comparing the traditional and flipped formats are warranted.

Transdisciplinary (TD) approaches are increasingly used to address complex public health problems such as childhood obesity. Compared to traditional grant-funded scientific projects among established scientists, those designed around a TD, team-based approach yielded greater publication output after three to five years. However, little is known about how a TD focus throughout graduate school training may affect students' publication-related productivity, impact, and collaboration. The objective of this study was to compare the publication patterns of students in traditional versus TD doctoral training programs. Productivity, impact, and collaboration of peer-reviewed publications were compared between traditional (n = 25) and TD (n = 11) students during the first five years of the TD program. Statistical differences were determined by t-test or chi square test at p < 0.05. The publication rate for TD students was 5.2 ± 10.1 (n = 56) compared to 3.6 ± 4.5 per traditional student (n = 82). Publication impact indicators were significantly higher for TD students vs. traditional students: 5.7 times more citations in Google Scholar, 6.1 times more citations in Scopus, 1.3 times higher journal impact factors, and a 1.4 times higher journal h-index. Collaboration indicators showed that publications by TD students had significantly more co-authors (1.3 times), and significantly more disciplines represented among co-authors (1.3 times), but not significantly more organizations represented per publication compared to traditional students. In conclusion, compared to doctoral students in traditional programs, TD students published works that were accepted into higher impact journals, were more frequently cited, and had more cross-disciplinary collaborations.

According to several studies from around the globe, the modified Misgav Ladach technique simplifies the surgical procedure for cesarean section, reduces operation time, costs, and complications, and optimizes obstetric and perinatal outcomes. Compare obstetric outcomes between patients operated on using traditional cesarean section technique and those operated on using modified Misgav Ladach technique. The study included 49 patients operated on using traditional cesarean section technique and 47 patients operated on using modified Misgav Ladach technique to compare the outcomes in both surgical techniques. The modified Misgav Ladach technique was associated with more benefits than those of the traditional technique: less surgical bleeding, less operation time, less analgesic total doses, less rescue analgesic doses and less need of more than one analgesic drug. The modified Misgav Ladach surgical technique was associated with better obstetric results than those of the traditional surgical technique; this concurs with the results reported by other national and international studies.

2014-01-01

The study compared the perceptions of nurses who participated in the clinical education of students using traditional and dedicated education unit (DEU) models. In the traditional model, faculty are the primary clinical instructors for students. In a DEU, nurses provide clinical instruction with faculty support. This mixed-methods study used surveys and interviews. Compared to nurses on traditional units, DEU nurses were more likely to agree that their unit welcomed students, had a strong commitment to teaching, and received professional development from clinical faculty. The nurses rated the learning gains of students as greater on DEUs than traditional units and viewed the leadership of the nurse manager and the quality of patient care as similar. The study provides evidence that, from the nurses' perspective, the DEU faculty-nurse partnership provides students with superior clinical education experiences and may improve nurse work satisfaction.

Current Advanced Cardiac Life Support (ACLS) course instruction involves a 2-day course with traditional lectures and limited team interaction. We wish to explore the advantages of a scenario-based performance-oriented team instruction (SPOTI) method to implement core ACLS skills for non-English-speaking international paramedic students. The objective of this study was to determine if scenario-based, performance-oriented team instruction (SPOTI) improves educational outcomes for the ACLS instruction of Korean paramedic students. Thirty Korean paramedic students were randomly selected into two groups. One group of 15 students was taught the traditional ACLS course. The other 15 students were instructed using a SPOTI method. Each group was tested using ACLS megacode examinations endorsed by the American Heart Association. All 30 students passed the ACLS megacode examination. In the traditional ACLS study group an average of 85% of the core skills were met. In the SPOTI study group an average of 93% of the core skills were met. In particular, the SPOTI study group excelled at physical examination skills such as airway opening, assessment of breathing, signs of circulation, and compression rates. In addition, the SPOTI group performed with higher marks on rhythm recognition compared to the traditional group. The traditional group performed with higher marks at providing proper drug dosages compared to the SPOTI students. However, the students enrolled in the SPOTI method resulted in higher megacode core compliance scores compared to students trained in traditional ACLS course instruction. These differences did not achieve statistical significance due to the small sample size. Copyright 2010 Elsevier Inc. All rights reserved.

In traditional Persian medicine, milk oversupply and its management have been described. The aim of this study was to investigate milk oversupply from the perspective of medieval Persian practitioners. In this study, some main medical resources of traditional Persian medicine such as Al-Havi and the Canon of Medicine were studied to extract valuable information about milk oversupply. Etiology of milk overproduction according to traditional Persian medicine is based on humors theory and cannot be easily compared with current medical concepts. Diet modifications and natural remedies have been applied for managing this condition but the majority of traditional Persian medicine interventions for reducing milk oversupply have not been scientifically investigated in modern medicine. The knowledge of milk oversupply in traditional Persian medicine may be helpful to conduct further related studies.

Comparison of student achievement among two science laboratory types: traditional and virtual

NASA Astrophysics Data System (ADS)

Reese, Mary Celeste

Technology has changed almost every aspect of our daily lives. It is not surprising then that technology has made its way into the classroom. More and more educators are utilizing technological resources in creative ways with the intent to enhance learning, including using virtual laboratories in the sciences in place of the "traditional" science laboratories. This has generated much discussion as to the influence on student achievement when online learning replaces the face-to-face contact between instructor and student. The purpose of this study was to discern differences in achievement of two laboratory instruction types: virtual laboratory and a traditional laboratory. Results of this study indicate statistical significant differences in student achievement defined by averages on quiz scores in virtual labs compared with traditional face-to-face laboratories and traditional laboratories result in greater student learning gains than virtual labs. Lecture exam averages were also greater for students enrolled in the traditional laboratories compared to students enrolled in the virtual laboratories. To account for possible differences in ability among students, a potential extraneous variable, GPA and ACT scores were used as covariates.

The purpose of this research study was to determine the overall effectiveness of computer-based laboratory compared with the traditional hands-on laboratory for improving students' science academic achievement and attitudes towards science subjects at the college and pre-college levels of education in the United States. Meta-analysis was used to synthesis the findings from 38 primary research studies conducted and/or reported in the United States between 1996 and 2006 that compared the effectiveness of computer-based laboratory with the traditional hands-on laboratory on measures related to science academic achievements and attitudes towards science subjects. The 38 primary research studies, with total subjects of 3,824 generated a total of 67 weighted individual effect sizes that were used in this meta-analysis. The study found that computer-based laboratory had small positive effect sizes over the traditional hands-on laboratory (ES = +0.26) on measures related to students' science academic achievements and attitudes towards science subjects (ES = +0.22). It was also found that computer-based laboratory produced more significant effects on physical science subjects compared to biological sciences (ES = +0.34, +0.17).

Bovine milk contains hundreds of diverse components, including proteins, peptides, amino acids, lipids, lactose, vitamins and minerals. Specifically, the lipid composition is influenced by different variables such as breed, feed and technological process. In this study the fatty acid and phospholipid compositions of different samples of butter and its by-products from the Parmigiano Reggiano cheese area, produced by industrial and traditional churning processes, were determined. The fatty acid composition of samples manufactured by the traditional method showed higher levels of monounsaturated and polyunsaturated fatty acids compared with industrial samples. In particular, the contents of n-3 fatty acids and conjugated linoleic acids were higher in samples produced by the traditional method than in samples produced industrially. Sample phospholipid composition also varied between the two technological processes. Phosphatidylethanolamine was the major phospholipid in cream, butter and buttermilk samples obtained by the industrial process as well as in cream and buttermilk samples from the traditional process, while phosphatidylcholine was the major phospholipid in traditionally produced butter. This result may be explained by the different churning processes causing different types of membrane disruption. Generally, samples produced traditionally had higher contents of total phospholipids; in particular, butter produced by the traditional method had a total phospholipid content 33% higher than that of industrially produced butter. The samples studied represent the two types of products present in the Parmigiano Reggiano cheese area, where the industrial churning process is widespread compared with the traditional processing of Reggiana cow's milk. This is because Reggiana cow's milk production is lower than that of other breeds and the traditional churning process is time-consuming and economically disadvantageous. However, its products have been demonstrated to contain more bioactive lipids compared with products obtained from other breeds and by the industrial process. © 2013 Society of Chemical Industry.

The effects of sex and gender role identity on perceived stress and coping among traditional and nontraditional students.

Jones, Kayla; Mendenhall, Sarah; Myers, Charlsie A

2016-01-01

This study examined differences in perceived stress and coping strategies based on gender role identity (GRI) and sex among traditional and nontraditional college students. Online surveys that assessed demographic information, GRI, and perceived stress were completed between October 2013 and March 2014 by 197 students. Nontraditional masculine male students reported higher levels of perceived stress compared with nontraditional androgynous male students. Traditional androgynous female students showed significantly lower levels of perceived stress compared with their masculine counterparts. Nontraditional female students reported using more approach coping strategies than their traditional male students, but there were no differences in coping strategies among traditional students. These results suggest traditional and nontraditional students have different levels of perceived stress based on sex and GRI. Thus, colleges and universities should consider designing workshops, programs, and seminars to address the needs of students based on their sex, GRI, and student type.

The participants in this study were preschool children aged 4 years old who were enrolled in Montessori and traditional preschools. The preschool children wore ActiGraph accelerometers. Accelerometers were initialized using 15-second intervals and sedentary behavior was defined as <200 counts/15-second. The accelerometry data were summarized into the average minutes per hour spent in sedentary behavior during the in-school, the after-school, and the total-day period. Mixed linear regression models were used to determine differences in the average time spent in sedentary behavior between children attending traditional and Montessori preschools, after adjusting for selected potential correlates of preschoolers' sedentary behavior. Children attending Montessori preschools spent less time in sedentary behavior than those attending traditional preschools during the in-school (44.4. min/hr vs. 47.1 min/hr, P = 0.03), after-school (42.8. min/hr vs. 44.7 min/hr, P = 0.04), and total-day (43.7 min/hr vs. 45.5 min/hr, P = 0. 009) periods. School type (Montessori or traditional), preschool setting (private or public), socio-demographic factors (age, gender, and socioeconomic status) were found to be significant predictors of preschoolers' sedentary behavior. Levels of objectively-measured sedentary behavior were significantly lower among children attending Montessori preschools compared to children attending traditional preschools. Future research should examine the specific characteristics of Montessori preschools that predict the lower levels of sedentary behavior among children attending these preschools compared to children attending traditional preschools.

The present study was conducted to investigate whether the calming effect induced by viewing traditional Chinese landscape paintings would make disengagement from that mental state more difficult, as measured by performance on a cognitive control task. In Experiment 1 we examined the subjective experience of viewing traditional Chinese landscape paintings vs. realistic oil landscape paintings in a behavioral study. Our results confirmed that, as predicted, traditional Chinese landscape paintings induce greater levels of relaxation and mind wandering and lower levels of object-oriented absorption and recognition, compared to realistic oil landscape paintings. In Experiment 2 we used functional Magnetic Resonance Imaging to explore the behavioral and neural effects of viewing traditional Chinese landscape paintings on a task requiring cognitive control (i.e., the flanker task)—administered immediately following exposure to paintings. Contrary to our prediction, the behavioral data demonstrated that compared to realistic oil landscape paintings, exposure to traditional Chinese landscape paintings had no effect on performance on the flanker task. However, the neural data demonstrated an interaction effect such that there was greater activation in the inferior parietal cortex and the superior frontal gyrus on incongruent compared with congruent flanker trials when participants switched from viewing traditional Chinese landscape paintings to the flanker task than when they switched from realistic oil landscape paintings. These results suggest that switching from traditional Chinese landscape paintings placed greater demands on the brain’s attention and working memory networks during the flanker task than did switching from realistic oil landscape paintings.

Surgical site infections (SSIs) are a significant complications in total knee arthroplasty (TKA). The purpose of this study was to evaluate if traditional vs. single-use instrumentation had an effect on SSI's. We compared SSI rates and costs of TKAs performed with single-use (449) and traditional (169) TKA instrumentation trays. Total OR Time was, on average, 30 min less when single-use instrumentation was used. SSIs decreased in the single-use group (n=1) compared to the traditional group (n=5) (P=0.006). Single-use instrumentation added $490 in initial costs; however it saved between $480 and $600. Single-use instrumentation may provide a benefit to the patient by potentially decreasing the risk of infection and reducing the overall hospital costs. Copyright © 2015 Elsevier Inc.

Historically, knee arthroplasties have been designed using average patient anatomy. Recent advances in imaging and manufacturing have facilitated the development of customized prostheses designed to fit the unique shape of individual patients. The purpose of this study is to determine if improving implant design through customized total knee arthroplasty (TKA) improves kinematic function. Using state-of-the-art mobile fluoroscopy, tibiofemoral kinematics were analyzed for 24 subjects with a customized individually made (CIM), cruciate-retaining TKA, and 14 subjects having an asymmetric condylar cruciate-retaining TKA. Subjects performed a weight-bearing deep knee bend and a rise from a seated position. Each patient was evaluated for weight-bearing range of motion, femorotibial translation, femorotibial axial rotation, and condylar liftoff occurrence. Subjects having a CIM TKA experienced greater weight-bearing knee flexion compared with the traditional posterior cruciate-retaining (PCR) TKA design. During flexion, the CIM TKA subjects consistently exhibited more posterior femoral rollback than the traditional PCR TKA subjects. The CIM TKA was found to have statistically greater axial rotation compared with the traditional PCR TKA (P = .05). Of note, only the CIM TKA patients experienced femoral internal rotation at full extension, as exhibited in a normal knee. Compared with the traditional PCR TKA, the CIM TKAs demonstrated minimal occurrences of paradoxical sliding and reverse rotation during flexion and extension. The CIM TKA subjects showed minimal liftoff and hence better stability in earlyflexion to midflexion compared with the traditional PCR subjects. The CIM TKA demonstrated kinematics more similar to a normal knee. Therefore, using customized implant technology through CIM TKA designs affords benefits including more normal motion compared with a traditional PCR TKA. Copyright © 2016 Elsevier Inc.

'Massive' transfusion is a poorly defined inclusion criteria for studies examining the blood and blood product that are used during trauma resuscitation. We aimed to compare the traditional definition of massive transfusion (≥10 units in 24 h) to a more acute definition of at least 5 units in 4 h. Multitrauma patients were subgrouped according to the traditional definition and compared with the acute definition. Demographics, presenting vital signs and blood results, management including transfusion practice and outcomes were retrospectively studied. Associations of transfused fresh frozen plasma:packed red blood cells (PRBC) ratios with mortality were studied. There were 927 patients who received PRBCs in the first 24 h, with 314 patients identified using the traditional definition and 303 patients using the acute definition. The patients identified using the traditional definition received 18 (12-29) units of PRBC in 24 h, significantly higher than those identified using the acute definition [15 (9-29) units, P<0.001]. The traditional definition excluded a significant proportion of patients who died in the emergency department. By using the acute definition to select a study sample, there seems to be an increase in mortality with fresh frozen plasma:PRBC ratio of 1 : 1 ratio compared with a 1 : 2 ratio. The traditional 'massive' transfusion definition not only 'dilutes' the potential study samples with a less acute group of patients, but also further excludes patients who die early. This latter group is most likely to be benefitted from any change to resuscitation practice. An acute definition of massive transfusion should be adopted when examining clinical practice during initial trauma resuscitation.

The Effectiveness Of Social Media (Facebook) Compared With More Traditional Advertising Methods for Recruiting Eligible Participants To Health Research Studies: A Randomized, Controlled Clinical Trial.

Recruiting participants for research studies can be difficult and costly. The popularity of social media platforms (eg, Facebook) has seen corresponding growth in the number of researchers turning to social networking sites and their embedded advertising frameworks to locate eligible participants for studies. Compared with traditional recruitment strategies such as print media, social media advertising has been shown to be favorable in terms of its reach (especially with hard-to-reach populations), cost effectiveness, and usability. However, to date, no studies have examined how participants recruited via social media progress through a study compared with those recruited using more traditional recruitment strategies. (1) Examine whether visiting the study website prior to being contacted by researchers creates self-screened participants who are more likely to progress through all study phases (eligible, enrolled, completed); (2) compare conversion percentages and cost effectiveness of each recruitment method at each study phase; and, (3) compare demographic and smoking characteristics of participants recruited through each strategy to determine if they attract similar samples. Participants recruited to a smoking cessation clinical trial were grouped by how they had become aware of the study: via social media (Facebook) or traditional media (eg, newspaper, flyers, radio, word of mouth). Groups were compared based on throughput data (conversion percentages and cost) as well as demographic and smoking characteristics. Visiting the study website did not result in individuals who were more likely to be eligible for (P=.24), enroll in (P=.20), or complete (P=.25) the study. While using social media was more cost effective than traditional methods when we examined earlier endpoints of the recruitment process (cost to obtain a screened respondent: AUD $22.73 vs $29.35; cost to obtain an eligible respondent: $37.56 vs $44.77), it was less cost effective in later endpoints (cost per enrolled participant: $56.34 vs $52.33; cost per completed participant: $103.66 vs $80.43). Participants recruited via social media were more likely to be younger (P=.001) and less confident in their quit attempts (P=.004) compared to those recruited via traditional methods. Our study suggests that while social media advertising may be effective in generating interest from potential participants, this strategy's ability to attract conscientious recruits is more questionable. Researchers considering using online resources (eg, social media advertising, matrix codes) should consider including prescreening questions to promote conversion percentages. Ultimately, researchers seeking to maximize their recruitment budget should consider using a combination of advertising strategies.

This study examined whether undergraduate college students' immediate recall and longer-term retention of introductory voice disorder concepts improved by using mini quiz games (MQGs; interactive knowledge tests in game format) compared with (a) traditional study alone, (b) MQGs and traditional study together, or (c) a no-study control condition. Ninety-three college students participated in proctored sessions in which they were given a pretest, viewed an online lecture on introductory voice disorder concepts, and then engaged in either no intervention or interventions including traditional study, MQG play, or both MQG play and traditional study, followed by an immediate recall posttest and longer-term retention follow-up test. Analyses suggested that the effects of all interventions (traditional study, MQG play, and the combination of the 2) were equivalent and resulted in significantly greater improvements from pretest to immediate recall posttest performance than the control condition. In contrast, MQGs and MQGs with traditional study, but not traditional study alone, showed better results for long-term retention than no study. Results provide preliminary support for the idea that there may be multiple effective learning modes, beyond traditional study, that enhance recall and retention of knowledge foundational to speech-language pathology clinical training and practice.

The present study was conducted to analyze the chemical composition, total phenolics content and antioxidant capacity of two whole corn (Zea mays) based meals traditional from Mexico: "traditional pinole" and "seven grain pinole"; and compare it with information available from ready to eat cereal products based on refined corn and whole grain cereals. Proximate analyses (moisture, ash, fat, protein and fiber) were carried out according to the procedures of AOAC, sugars content was determined by HPLC method; calcium and iron were quantified using atomic absorption spectroscopy. Total phenolic compounds were determined by Folin-Ciocalteu spectrophotometric method; the antiradical capacity was determined by DPPH colorimetric method and total antioxidant capacity was determined by FRAP method. Traditional and seven grain pinole presented higher energy content and nutrient density (protein and fat) than processed cereals. Calcium content was higher in processed cereals than pinole; seven grain pinole presented the highest conentration of iron. Polyphenolic concentration was higher in both kinds of pinole compared to processed cereals; traditional pinole presented the highest antioxidant activity measured by DPPH and FRAP methods. The results provide evidence about the important nutrient and antioxidant content of traditional and seven grain pinole compared to processed cereals based on corn and other grains. It is recommended their incorporation in to regular diet as a healthy food, with a good protein level, low sugar content and good antioxidant capacity.

Silicon photomultipliers (SiPMs) are a new generation of semiconductor-based photon counting devices with the merits of low weight, low power consumption and low voltage operation, promising to meet the needs of space particle physics experiments. In this paper, comparative studies of SiPMs and traditional vacuum photomultiplier tubes (PMTs) have been performed regarding the basic properties of dark currents, dark counts and excess noise factors. The intrinsic optical crosstalk effect of SiPMs was evaluated.

Puzzle based teaching versus traditional instruction in electrocardiogram interpretation for medical students--a pilot study.

2009-01-13

Most medical professionals are expected to possess basic electrocardiogram (EKG) interpretation skills. But, published data suggests that residents' and physicians' EKG interpretation skills are suboptimal. Learning styles differ among medical students; individualization of teaching methods has been shown to be viable and may result in improved learning. Puzzles have been shown to facilitate learning in a relaxed environment. The objective of this study was to assess efficacy of teaching puzzle in EKG interpretation skills among medical students. This is a reader blinded crossover trial. Third year medical students from College of Human Medicine, Michigan State University participated in this study. Two groups (n = 9) received two traditional EKG interpretation skills lectures followed by a standardized exam and two extra sessions with the teaching puzzle and a different exam. Two other groups (n = 6) received identical courses and exams with the puzzle session first followed by the traditional teaching. EKG interpretation scores on final test were used as main outcome measure. The average score after only traditional teaching was 4.07 +/- 2.08 while after only the puzzle session was 4.04 +/- 2.36 (p = 0.97). The average improvement after the traditional session was followed up with a puzzle session was 2.53 +/- 1.94 while the average improvement after the puzzle session was followed with the traditional session was 2.08 +/- 1.73 (p = 0.67). The final EKG exam score for this cohort (n = 15) was 84.1 compared to 86.6 (p = 0.22) for a comparable sample of medical students (n = 15) at a different campus. Teaching EKG interpretation with puzzles is comparable to traditional teaching and may be particularly useful for certain subgroups of students. Puzzle session are more interactive and relaxing, and warrant further investigations on larger scale.

MINI: Fourteen hundred consecutive patients were investigated for evaluating the utility of waterless hand rub before orthopaedic surgery. The risk in the surgical site infection incidence was the same, but costs of liquids used for hand hygiene were cheaper and the hand hygiene time was shorter for waterless protocol, compared with traditional hand scrub. A retrospective cohort study with prospectively collected data. The aim of this study was to compare SSI incidences, the cost of hand hygiene agents, and hand hygiene time between the traditional hand scrub and the waterless hand rub protocols before orthopedic surgery. Surgical site infections (SSI) prolong hospitalization and are a leading nosocomial cause of morbidity and a source of excess cost. Recently, a waterless hand rub protocol comprising alcohol based chlorhexidine gluconate for use before surgery was developed, but no studies have yet examined its utility in orthopedic surgery. Fourteen hundred consecutive patients who underwent orthopedic surgery (spine, joint replacement, hand, and trauma surgeries) in our hospital since April 1, 2012 were included. A total of 712 cases underwent following traditional hand scrub between April 1, 2012 and April 30, 2013 and 688 cases underwent following waterless hand rub between June 1, 2013 and April 30, 2014. We compared SSI incidences within all and each subcategory between two hand hygiene protocols. All patients were screened for SSI within 1 year after surgery. We compared the cost of hand hygiene agents and hand hygiene time between two groups. The SSI incidences were 1.3% (9 of 712) following the traditional protocol (2 deep and 7 superficial infections) and 1.1% (8 of 688) following the waterless protocol (all superficial infections). There were no significant differences between the two groups. The costs of liquids used for one hand hygiene were about $2 for traditional hand scrub and less than $1 for waterless hand rub. The mean hand hygiene time was 264 seconds with the traditional protocol and 160 seconds with the waterless protocol. Waterless hand rub with an alcohol based chlorhexidine gluconate solution can be a safe, quick, and cost-effective alternative to traditional hand scrub. 3.

Kortemeyer, Gerd

2016-10-01

The study compares the work habits of two student groups in an introductory physics course, one in traditional and one in online sections. Both groups shared the same online materials and online homework, as well as the same discussion boards and examinations, but one group in addition had traditional lectures. The groups were compared with respect to amount and frequency of access to different online course resources. It was found that with few exceptions, both groups exhibited very similar work habits. Students in the online sections more frequently accessed content pages and more frequently contributed to course discussions. It was also found that regular access of the materials throughout the week, rather than only on homework deadline nights, is a predictor of success on examinations, and that this indicator is more reliable for students in the online sections. Overall, though, the effect of traditional lectures is minimal.

The rapid improvements in medical sciences and the ever-increasing related data, however, require novel methods of instruction. One such method, which has been given less than due attention in Iran, is problem-based learning (PBL). In this study, we aimed to evaluate the impact of study skills and the PBL methods on short and long-term retention of information provided for medical students in the course of respiratory physiology and compare it with traditional learning method. In this study, 39 medical students from Medical School of Kerman University of Medical Sciences, Kerman, Iran (2006-2010) were enrolled in the study and allocated randomly in three equal groups (13 in each group). All groups underwent a pre-test to be assessed for their basic information regarding respiratory physiology. Two groups were instructed using the traditional method, and one group used PBL. Among the two groups of the traditional method, one was instructed about study skills and the other was not. Once the PBL group took the study skill workshop, they were aided by tutors for their education. In the final term test, those students who had learned study skills and were instructed with the traditional method scored higher compared to other groups (p < 0.05). However, in the 1 year (p < 0.05) and 4 year (p < 0.01) interval examinations, the PBL group achieved significantly higher scores. Despite the fact that PBL had no positive effect on the final term exam of our students, it yielded a more profound and retained understanding of the subject course. Moreover, considering the positive effect of study skills on long-term student scores, we recommend students to receive instructions regarding the appropriate study skills when initiated into universities.

Comparative study on stiffness properties of WOODCAST and conventional casting materials.

Pirhonen, Eija; Pärssinen, Antti; Pelto, Mika

2013-08-01

Plaster-of-Paris and synthetic materials (e.g. fibreglass) have been in clinical use as casting materials for decades. An innovative casting material, WOODCAST, brings interesting alternatives to the traditional materials. The aim of this study was to compare the stiffness properties of the WOODCAST material to traditional casting materials. In immobilization by casting, materials with variable stiffness properties are required. Ring stiffness of cylindrical samples correlates well with cast rigidity. For load-bearing structures, the use of the WOODCAST Splint is recommended as equally high stiffness was obtained with the WOODCAST Splint as was with fibreglass. The WOODCAST 2 mm product is optimal for structures where some elasticity is required, and WOODCAST Ribbon can be used in any WOODCAST structure where further reinforcement is needed. The results show that WOODCAST material can be used in replacing traditional casting materials used in extremity immobilization. The mechanical properties of casting material play an important role in safe and effective fracture immobilization. Stiffness properties of the WOODCAST casting material and conventional materials - fibreglass and plaster-of-Paris - were analysed in this study. The WOODCAST Splint appears to compare favorably with traditional materials such as Scotchcast.

Objectively measured sedentary behavior in preschool children: comparison between Montessori and traditional preschools

PubMed Central

2013-01-01

Background This study aimed to compare the levels of objectively-measured sedentary behavior in children attending Montessori preschools with those attending traditional preschools. Methods The participants in this study were preschool children aged 4 years old who were enrolled in Montessori and traditional preschools. The preschool children wore ActiGraph accelerometers. Accelerometers were initialized using 15-second intervals and sedentary behavior was defined as <200 counts/15-second. The accelerometry data were summarized into the average minutes per hour spent in sedentary behavior during the in-school, the after-school, and the total-day period. Mixed linear regression models were used to determine differences in the average time spent in sedentary behavior between children attending traditional and Montessori preschools, after adjusting for selected potential correlates of preschoolers’ sedentary behavior. Results Children attending Montessori preschools spent less time in sedentary behavior than those attending traditional preschools during the in-school (44.4. min/hr vs. 47.1 min/hr, P = 0.03), after-school (42.8. min/hr vs. 44.7 min/hr, P = 0.04), and total-day (43.7 min/hr vs. 45.5 min/hr, P = 0. 009) periods. School type (Montessori or traditional), preschool setting (private or public), socio-demographic factors (age, gender, and socioeconomic status) were found to be significant predictors of preschoolers’ sedentary behavior. Conclusions Levels of objectively-measured sedentary behavior were significantly lower among children attending Montessori preschools compared to children attending traditional preschools. Future research should examine the specific characteristics of Montessori preschools that predict the lower levels of sedentary behavior among children attending these preschools compared to children attending traditional preschools.

Draganova, Vanya Y.; Matsumoto, Hiroshi; Tsuzuki, Kazuyo

2017-10-01

Notwithstanding apparent differences, Japanese and Bulgarian traditional residential houses share a lot of common features - building materials, building techniques, even layout design. Despite the similarities, these two types of houses have not been compared so far. The study initiates such comparison. The focus is on houses in areas with similar climate in both countries. Current legislation requirements are compared, as well as the criteria for thermal comfort of people. Achieving high energy performance results from a dynamic system of 4 main key factors - thermal comfort range, heating/cooling source, building envelope and climatic conditions. A change in any single one of them can affect the final energy performance. However, it can be expected that a combination of changes in more than one factor usually occurs. The aim of this study is to evaluate the correlation between the thermal performance of building envelope designed under current regulations and a traditional one, having in mind the different thermal comfort range in the two countries. A sample building model is calculated in Scenario 1 - Japanese traditional building fabric, Scenario 2 - Bulgarian traditional building fabric and Scenario 3 - meeting the requirements of the more demanding current regulations. The energy modelling is conducted using EnergyPlus through OpenStudio cross-platform of software tools. The 3D geometry for the simulation is created using OpenStudio SketchUp Plug-in. Equal number of inhabitants, electricity consumption and natural ventilation is assumed. The results show that overall low energy consumption can be achieved using traditional building fabric as well, when paired with a wider thermal comfort range. Under these conditions traditional building design is still viable today. This knowledge can reestablish the use of traditional building fabric in contemporary design, stimulate preservation of local culture, building traditions and community identity.

The aim of this study was to compare the postoperative complications during genioplasty using piezosurgery devices or traditional rotating drills. Forty patients underwent genioplasty to solve their chin anomalies. This study showed that, using piezosurgery, pain and swelling were reduced compared to the traditional technique in the immediate postoperative period of healing (within 15 days). Paresthesia was observed in all patients up to 15th postoperative day, independently of the used surgical technique, but at the sixth postoperative month it was completely absent.

In 2011, Macquarie University moved to a three-session academic year which included two 13-week sessions (traditional mode) and one seven-week session (intensive mode). This study was designed to compare the intensive and traditional modes of delivery in a unit of undergraduate neuroanatomy. The new intensive mode neuroanatomy unit provided the same quantity and quality of material to the same standard, delivered by the same teachers and over the same total hours, but in a shorter timeframe. All students enrolled in session 2 (traditional mode) and session 3 (intensive mode) were invited to participate in this study. The main outcome measures were the final course grades and level of satisfaction with the course. Although there was no significant difference between the two cohorts in self-rated level of knowledge (P = 0.148), the traditional mode cohort achieved significantly higher final grades compared to the intensive mode cohort (P = 0.001). Similarly, the distribution of final grades was also different between the two cohorts. The two cohorts were equally satisfied with the unit overall, and with the lectures and tutorials. However, the intensive mode cohort was more satisfied with the laboratory practical classes compared to the traditional mode cohort (P < 0.001). Thus this study demonstrates that in the case of neuroanatomy, which is high in content, when the course is taught to the same standards as exist in the traditional mode of delivery, the students do not do as well even though they enjoy the course equally.

The "4-stage approach" has been widely accepted for practical skill training replacing the traditional 2 stages ("see one, do one"). However, the superior effectiveness of the 4-stage approach was never proved. To evaluate whether skill training with the 4-stage approach results in shorter performance time needed for a successful percutaneous needle-puncture cricothyroidotomy, and consequently in a reduced number of attempts needed to perform the skill in <60s compared to traditional teaching. Randomized controlled single-blinded parallel group study at the University Hospital Bern. With IRB approval and informed consent 128 undergraduate medical students were randomized in four groups: traditional teaching, no stage 2, no stage 3, and 4-stage approach for the training of cricothyroidotomy. Everyone watched a video of the cricothyroidotomy as stage 1 followed by skill training in the respective teaching group. Participants had to perform the cricothyroidotomy 10 times on skin-covered pig larynxes. Performance time was measured from skin palpation to trachea ventilation. Study participants filled out a self-rating on competency during the training. Performance time for each attempt was comparable in all groups and improved similarly to reach a performance time of <60 s. Self-rating revealed that all groups felt equally competent throughout. Even if the 4-stage approach is widely accepted and used as a didactic method for skill teaching we could not find evidence that its use or omitting stage 2 or 3 results in superior learning of an emergency skill compared to traditional teaching.

Cat dissection and human cadaver prosection versus sculpting human structures from clay: A comparison of alternate approaches to human anatomy laboratory education

NASA Astrophysics Data System (ADS)

Waters, John R.

Dissection and vivisection are traditional approaches to biology laboratory education. In the case of human anatomy teaching laboratories, there is a long tradition of using human and animal cadaver specimens in the classroom. In a review of the literature comparing traditional dissection and vivisection lessons to alternative lessons designed to reduce the time spent dissecting or the numbers of animals used, we conclude that it is difficult to come to any conclusion regarding the efficacy of different approaches. An analysis of the literature is confounded because many studies have very low statistical power or other methodological weaknesses, and investigators rely on a wide variety of testing instruments to measure an equally varied number of course objectives. Additional well designed studies are necessary before educators can reach any informed conclusions about the efficacy of traditional versus alternative approaches to laboratory education. In our experiments, we compared a traditional cat dissection based undergraduate human anatomy lesson to an alternative where students sculpted human muscles onto plastic human skeletons. Students in the alternative treatment performed significantly better than their peers in the traditional treatment when answering both lower and higher order human anatomy questions. In a subsequent experiment with a similar design, we concluded that the superior performance of the students in the alternative treatment on anatomy exams was likely due to the similarity between the human anatomy representation studied in lab, and the human anatomy questions asked on the exams. When the anatomy questions were presented in the context of a cat specimen, students in the traditional cat dissection treatment outperformed their peers in the alternative treatment. In a final experiment where student performance on a human anatomy exam was compared between a traditional prosected human cadaver treatment and the alternative clay sculpting treatment, no significant difference were detected, suggesting that the complexity or simplicity of the anatomy representation is less important than the similarity between the learning experience and the testing experience.

Comparing Costs of Traditional and Specialty Probation for People With Serious Mental Illness.

Specialty mental health probation reduces the likelihood of rearrest for people with mental illness, who are overrepresented in the justice system. This study tested whether specialty probation was associated with lower costs than traditional probation during the two years after placement in probation. A longitudinal, matched study compared costs of behavioral health care and criminal justice contacts among 359 probationers with mental illness at prototypic specialty or traditional agencies. Compared with traditional officers, specialty officers supervised smaller caseloads, established better relationships with supervisees, and participated more in treatment. Participants and officers were interviewed, and administrative databases were integrated to capture service use and criminal justice contacts. Unit costs were attached to these data to estimate costs incurred by each participant over two years. Cost differences were estimated by using machine-learning algorithms combined with targeted maximum-likelihood estimation (TMLE), a double-robust estimator that accounts for associations between confounders and both treatment assignment and outcomes. Specialty probation cost $11,826 (p<.001) less per participant than traditional probation, with overall savings of about 51%. Specialty and traditional probation did not differ in criminal justice costs because the additional costs for supervision of specialty caseloads were offset by reduced recidivism. However, for behavioral health care, specialty probation cost an estimated $14,049 (p<.001) less per client than traditional probation. Greater outpatient costs were more than offset by reduced emergency, inpatient, and residential costs. Well-implemented specialty probation yielded substantial savings-and should be considered in justice reform efforts for people with mental illness.

A comparison of online versus face-to-face teaching delivery in statistics instruction for undergraduate health science students.

PubMed

Lu, Fletcher; Lemonde, Manon

2013-12-01

The objective of this study was to assess if online teaching delivery produces comparable student test performance as the traditional face-to-face approach irrespective of academic aptitude. This study involves a quasi-experimental comparison of student performance in an undergraduate health science statistics course partitioned in two ways. The first partition involves one group of students taught with a traditional face-to-face classroom approach and the other through a completely online instructional approach. The second partition of the subjects categorized the academic aptitude of the students into groups of higher and lower academically performing based on their assignment grades during the course. Controls that were placed on the study to reduce the possibility of confounding variables were: the same instructor taught both groups covering the same subject information, using the same assessment methods and delivered over the same period of time. The results of this study indicate that online teaching delivery is as effective as a traditional face-to-face approach in terms of producing comparable student test performance but only if the student is academically higher performing. For academically lower performing students, the online delivery method produced significantly poorer student test results compared to those lower performing students taught in a traditional face-to-face environment.

For immobile patients, a body wash in bed is sometimes the only bathing option. Traditionally, the bed bath is performed with water and soap. However, alternatives are increasingly used in health care. Washing without water is one such alternative that has been claimed to offer several advantages, such as improved hygiene and skin condition. This systematic review aims to provide a comprehensive overview of the evidence on outcomes of the washing without water concept compared to the traditional bed bath. Controlled trials about washing without water outcomes published after 1994 were collected by means of a systematic literature search in CINAHL, Embase, MEDLINE, and PUBMED at the 25th of February, 2016. Additionally, references and citations were searched and experts contacted. Studies were eligible if (1) the study designs included outcomes of washing without water products developed for the full body wash compared to the traditional bed bath, and (2) they were controlled trials. Two researchers independently used a standardized quality checklist to assess the methodological quality of the eligible studies. Finally, outcomes were categorized in (1) physiological outcomes related to hygiene and skin condition, (2) stakeholder-related outcomes, and (3) organizational outcomes in the data synthesis. Out of 33 potentially relevant articles subjected to full text screening, six studies met the eligibility criteria. Only two studies (of the same research group) were considered of high quality. The results of these high quality studies show that washing without water performed better than the traditional bed bath regarding skin abnormalities and bathing completeness. No differences between washing without water and the traditional bed bath were found for outcomes related to significant skin lesions, resistance during bathing and costs in the studies of high quality. There is limited moderate to high quality evidence that washing without water is not inferior to the traditional bed bath. Future research on washing without water is needed and should pay special attention to costs, hygiene, and to stakeholder-related outcomes, such as experiences and value perceptions of patients, nursing staff and family.

Fundamentals of nursing course are prerequisite to providing comprehensive nursing care. Despite development of technology on nursing education, effectiveness of using e-learning methods in fundamentals of nursing course is unclear in clinical skills laboratory for nursing students. The aim of this study was to compare the effect of blended learning (combining e-learning with traditional learning methods) with traditional learning alone on nursing students' scores. A two-group post-test experimental study was administered from February 2014 to February 2015. Two groups of nursing students who were taking the fundamentals of nursing course in Iran were compared. Sixty nursing students were selected as control group (just traditional learning methods) and experimental group (combining e-learning with traditional learning methods) for two consecutive semesters. Both groups participated in Objective Structured Clinical Examination (OSCE) and were evaluated in the same way using a prepared checklist and questionnaire of satisfaction. Statistical analysis was conducted through SPSS software version 16. Findings of this study reflected that mean of midterm (t = 2.00, p = 0.04) and final score (t = 2.50, p = 0.01) of the intervention group (combining e-learning with traditional learning methods) were significantly higher than the control group (traditional learning methods). The satisfaction of male students in intervention group was higher than in females (t = 2.60, p = 0.01). Based on the findings, this study suggests that the use of combining traditional learning methods with e-learning methods such as applying educational website and interactive online resources for fundamentals of nursing course instruction can be an effective supplement for improving nursing students' clinical skills.

To establish a method for studying efficacious materials of traditional Chinese medicines from an overall perspective. Carthamus tinctorius was taken the example. Its major components were depleted by preparing liquid chromatography. Afterwards, the samples with major components depleted were evaluated for their antioxidant effect, so as to compare and analyze the major efficacious materials of C. tinctorius with antioxidant activity and the contributions. Seven major components were depleted from C. tinctorius samples, and six of them were identified with MS data and control comparison. After all of the samples including depleted materials are compared and evaluated for their antioxidant effect, the findings showed that hydroxysafflor yellow A, anhydrosafflor yellow B and 6-hydroxykaempferol-3, 6-di-O-glucoside-7-O-glucuronide were the major efficacious materials. This study explored a novel and effective method for studying efficacious materials of traditional Chinese medicines. Through this method, we could explain the direct and indirect contributions of different components to the efficacy of traditional Chinese medicines, and make the efficacious material expression of traditional Chinese medicines clearer.

To determine if patients using human immunodeficiency virus (HIV)-specialized pharmacies have greater adherence to drugs used to treat comorbid conditions and HIV compared with patients who use traditional pharmacies. Retrospective cohort study, with patients' propensity matched based on pharmacy use: HIV-specialized versus traditional. Nationwide pharmacy chain. Adult patients who filled at least two prescriptions for an antiretroviral therapy (ART). Patients also needed to have at least two prescriptions for an angiotensin-converting enzyme (ACE) inhibitor/angiotensin receptor blocker (ARB) or a statin for analyses examining comorbid conditions. Proportion of days covered (PDC). The adherence analyses for ART, ACE inhibitors/ARBs, and statins included 14,278, 1,484, and 1,372 pairs, respectively. The mean PDC for ART patients using HIV-specialized pharmacies was higher than that for patients using traditional pharmacies (86.20% vs. 81.87%; P <0.0001). Patients taking ACE inhibitors/ARBs in the specialized group also had a higher mean PDC compared with patients in the traditional group (82.61 vs. 79.66; P = 0.0002), as did specialized pharmacy users in the statin group (83.77 vs. 81.29; P = 0.0009). HIV patients managed by an HIV-specialized pharmacy have significantly higher adherence to medication for comorbid conditions compared with patients using traditional pharmacies. Patients of HIV-specialized pharmacies also have significantly higher adherence to ART compared with peers using traditional pharmacies.

Liposuction is the most performed surgical procedure in Brazil and the second in the world. In recent years, new technologies have been developed in an attempt to improve liposuction, such as laser. The objective of this study is to evaluate the efficacy and safety of laser-assisted liposuction (LAL) compared to traditional liposuction through a systematic review of the literature. The search strategy used was the combination of the descriptors [lasers (MeSH Terms)] and (lipectomy [MeSH Terms]) in the PubMed database. Two independent researchers carried out the reading of the abstracts and selection of the studies according to the eligibility criteria. The risks of study bias were evaluated using an instrument similar to that used by the Cochrane Collaboration. Initially, 80 studies were obtained and, after evaluating the eligibility criteria, seven remained. Five of them observed that LAL has benefits when compared to traditional liposuction, and the main outcomes were compared with regard to histological analysis (2 products), further reduction of subcutaneous fat (2), better retraction of the skin (3), and higher personal satisfaction of the patient (2). The qualitative assessment identified high risks of bias in various areas in the studies. Although studies have concluded that LAL promotes greater fat reduction, better skin retraction, and greater patient satisfaction compared to traditional liposuction, the high bias impedes a more reliable conclusion.

1995-05-01

Reflex therapy is one of numerous applications of low-energy laser radiation in medical treatment. The advantages of this therapy in comparison with traditional acupuncture include technical simplicity, absence of pain, and, as a consequence of the complete noninvasiveness of the procedure, the absence of risk of contracting AIDS or other infectious diseases. However, no definitive results have been published regarding the comparative effectiveness of the two approaches to reflex therapy. In view of the neurohumoral role in the curative effects of reflex therapy, we compared laser acupuncture and the traditional needle technique in relation to changes in the serum concentrations of the principal sexual and gonadotropic hormones in hypofertile men.

Disease management's (DM's) value largely depends on achieving and maintaining participation. Simply being enrolled in a program does not guarantee engaged participation by enrollees, a necessary factor to achieve the improved health outcomes and subsequent reduced health care costs that are the ultimate objective of DM. The objective of this study is to test the hypothesis that an integrated disease management (IDM) protocol (patent-pending), which combines telephonic-delivered disease management (TDM) with a worksite-based primary care center and pharmacy delivery, yields higher patient retention rates than traditional remote DM alone. An earlier study of the IDM protocol found that integrating a worksite-based primary care and pharmacy delivery system with traditional telephonic-based DM substantially increased contact, enrollment, and engagement rates compared to traditional stand-alone telephonic DM. This prospective cohort study tracks contact and enrollment rates for persons assigned to either IDM or traditional TDM protocols and compares participation rates at 6- and 12-month intervals as well as measures of continued retention in the DM program. The IDM protocol showed a significant improvement in participation persistence over traditional TDM. Integrating a worksite-based primary care and pharmacy delivery system led by "trusted clinicians at the workplace"trade mark with traditional telephonic-based DM not only increases contact and enrollment rates, but also results in higher patient engagement and retention. These improvements in participation are expected to result in improved outcomes for a larger proportion of the target population than traditional telephonic DM.

A comparative study on the traditional Indian Shodhana and Chinese processing methods for aconite roots by characterization and determination of the major components

PubMed Central

2013-01-01

Background Aconitum is an indispensable entity of the traditional medicine therapy in Ayurveda and Traditional Chinese medicine (TCM), in spite of its known fatal toxicity characteristics. The prolonged use of this drug, irrespective of its known lethal effects, is governed by the practice of effective detoxification processes that have been used for decades. However, the processing methods of Ayurveda and TCM are different, and no comparative study has been carried out to evaluate their differences. The objective of the present study was to carry out comparative chemical profiling of the roots of Aconitum heterophyllum Wall, A. carmichaelii Debx., and A. kusnezoffii Reichb. after application of two detoxification methods used in Ayurveda and one method used in TCM . Results Analysis of the processed samples was carried out by ultra-high performance liquid chromatography combined with quadrupole time-of-flight mass spectrometry (UHPLC-QTOF/MS). The results obtained in the study demonstrate that all three processing methods used in Ayurveda and TCM effectively extract the diester diterpenoid alkaloids and led to their conversion into monoester diterpenoid alkaloids. The efficiency of the processes in reduction of toxic alkaloid contents can be stated as: Processing with water > Shodhana with cow milk > Shodhana with cow urine. The analysis method was validated as per ICH-Q2R1 guidelines and all the parameters were found to comply with the recommendations stated in the guidelines. Conclusions There have been no reports till date, to compare the processing methods used in Ayurveda with the methods used in TCM for detoxification of aconite roots. Our study demonstrates that, these methods used in both the traditional systems of medicine, efficiently detoxify the aconite roots. Amongst the three selected procedures, the TCM method of decoction with water is the most efficient. Through experimental evidences, we prove the conversion of toxic diester diterpenoid alkaloids to relatively safer monoester diterpenoid alkaloids. Thus, this study demonstrates that comparative study on the traditional experiences accumulated in different medical systems is useful for expanding their respective applications. PMID:24156713

A comparative analysis of traditional and online lab science transfer courses in the rural community college

NASA Astrophysics Data System (ADS)

Scott, Andrea

Through distance learning, the community college system has moved beyond geographical boundaries to serve all students and provide educational opportunities at a distance to individuals previously out of reach of the college community. With the inception of the Mississippi Virtual Community College (MSVCC) in January 2000, Mississippi's public community colleges have experienced unprecedented growth in online enrollments and online course offerings to include the laboratory sciences; however, transfer of online lab science courses are problematic for individuals who wish to gain admittance to Medical, Dental, and Pharmacy schools in Mississippi. Currently online lab science courses are not accepted for transfer for students seeking admission to Mississippi Medical, Dental, or Pharmacy schools. The need for this study, the statement of the problem, and the purpose of the study address transfer issues related to the transfer of online lab science courses in Mississippi and the impact of such on the student and community college. The study also addresses existing doubts regarding online course delivery as a viable method of lab science delivery. The purpose of the study was to investigate differences between online instructional delivery as compared to traditional face-to-face delivery with the following research questions to: (1) Investigate the perception of quality of online courses as compared to traditional face-to-face courses. (2) Investigate the difference in student performance in online transfer lab science courses as compared to student performance in traditional face-to-face lab science courses. The results of this 13 semester study show significant differences in both perception of quality and student performance between online instructional delivery as compared to traditional face-to-face delivery. The findings demonstrate a need for Mississippi Dental, Medical, and Pharmacy schools to reexamine the articulation agreement between IHL and Community and Junior Colleges and consider accepting online lab sciences courses taken at the community college as transfer for admission to Medical, Dental, and Pharmacy schools. Conclusions are included in the study; however, additional studies are needed to address the issue of student performance in the online lab science classroom.

2016-07-01

This systematic review was conducted to evaluate the effect of Olympic weightlifting (OW) on vertical jump (VJ) height compared to a control condition, traditional resistance training and plyometric training. Five electronic databases were searched using terms related to OW and VJ. Studies needed to include at least one OW exercise, an intervention lasting ≥6 weeks; a comparison group of control, traditional resistance training or plyometric training; and to have measured VJ height. The methodological quality of studies was assessed using the Downs and Black Checklist. Random and fixed effects meta-analyses were performed to pool the results of the included studies and generate a weighted mean effect size (ES). Six studies (seven articles) were included in the meta-analyses and described a total of 232 participants (175 athletes and 57 physical education students) with resistance training experience, aged 19.5±2.2 years. Three studies compared OW versus control; four studies compared OW versus traditional resistance training; and three studies compared OW versus plyometric training. Meta-analyses indicated OW improved VJ height by 7.7% (95% CI 3.4 to 5.4 cm) compared to control (ES=0.62, p=0.03) and by 5.1% (95% CI 2.2 to 3.0 cm) compared to traditional resistance training (ES=0.64 p=0.00004). Change in VJ height was not different for OW versus plyometric training. OW is an effective training method to improve VJ height. The similar effects observed for OW and plyometric training on VJ height suggests that either of these methods would be beneficial when devising training programmes to improve VJ height.

The Effectiveness Of Social Media (Facebook) Compared With More Traditional Advertising Methods for Recruiting Eligible Participants To Health Research Studies: A Randomized, Controlled Clinical Trial

PubMed Central

Thow, Megan; Ferguson, Stuart G

2016-01-01

Background Recruiting participants for research studies can be difficult and costly. The popularity of social media platforms (eg, Facebook) has seen corresponding growth in the number of researchers turning to social networking sites and their embedded advertising frameworks to locate eligible participants for studies. Compared with traditional recruitment strategies such as print media, social media advertising has been shown to be favorable in terms of its reach (especially with hard-to-reach populations), cost effectiveness, and usability. However, to date, no studies have examined how participants recruited via social media progress through a study compared with those recruited using more traditional recruitment strategies. Objectives (1) Examine whether visiting the study website prior to being contacted by researchers creates self-screened participants who are more likely to progress through all study phases (eligible, enrolled, completed); (2) compare conversion percentages and cost effectiveness of each recruitment method at each study phase; and, (3) compare demographic and smoking characteristics of participants recruited through each strategy to determine if they attract similar samples. Methods Participants recruited to a smoking cessation clinical trial were grouped by how they had become aware of the study: via social media (Facebook) or traditional media (eg, newspaper, flyers, radio, word of mouth). Groups were compared based on throughput data (conversion percentages and cost) as well as demographic and smoking characteristics. Results Visiting the study website did not result in individuals who were more likely to be eligible for (P=.24), enroll in (P=.20), or complete (P=.25) the study. While using social media was more cost effective than traditional methods when we examined earlier endpoints of the recruitment process (cost to obtain a screened respondent: AUD $22.73 vs $29.35; cost to obtain an eligible respondent: $37.56 vs $44.77), it was less cost effective in later endpoints (cost per enrolled participant: $56.34 vs $52.33; cost per completed participant: $103.66 vs $80.43). Participants recruited via social media were more likely to be younger (P=.001) and less confident in their quit attempts (P=.004) compared to those recruited via traditional methods. Conclusions Our study suggests that while social media advertising may be effective in generating interest from potential participants, this strategy’s ability to attract conscientious recruits is more questionable. Researchers considering using online resources (eg, social media advertising, matrix codes) should consider including prescreening questions to promote conversion percentages. Ultimately, researchers seeking to maximize their recruitment budget should consider using a combination of advertising strategies.

Analyzing Flash Flood Data in an Ultra-Urban Region

NASA Astrophysics Data System (ADS)

Smith, B. K.; Rodriguez, S.

2016-12-01

New York City is an ultra-urban region, with combined sewers and buried stream channels. Traditional flood studies rely on the presence of stream gages to detect flood stage and discharge, but ultra-urban regions frequently lack the surface stream channels and gages necessary for this approach. In this study we aggregate multiple non-traditional data for detecting flash flood events. These data including phone call reports, city records, and, for one particular flood event, news reports and social media reports. These data are compared with high-resolution bias-corrected radar rainfall fields to study flash flood events in New York City. We seek to determine if these non-traditional data will allow for a comprehensive study of rainfall-runoff relationships in New York City. We also seek to map warm season rainfall heterogeneities in the city and to compare them to spatial distribution of reported flood occurrence.

2017-12-01

Few studies have examined differences in emotional problems and personality of traditional bullies and cyberbullies. The present study aimed to determine whether those engaged in cyberbullying differ in emotional problems, and personality from those engage in traditional bullying perpetration. An Argentinean sample of 898 high school students was recruited (56% female; mean age = 15.2 SD = 1.6). Adolescents completed measures of traditional bullying, cyberbullying, self-esteem, anxiety, depression, and personality. A 6% were traditional bullies; 8%, cyberbullies; and 4% were involved in both forms; the remainders were non involved. Results indicated that cyberbullies showed less depression and anxiety than traditional bullies. Also, cyberbullies scored low in neuroticism and high in agreeableness compared to traditional bullies. The results suggest that cyberbullies are characterized by an emotional and personality profile different from traditional bullies. In the discussion we analyze the implications of these results.

The importance of using technologies such as e-learning in different disciplines is discussed in the literature. Researchers have measured the effectiveness of e-learning in a number of fields.Considering the lack of research on the effectiveness of online learning in dental education particularly in Iran, the advantages of these learning methods and the positive university atmosphere regarding the use of online learning. This study, therefore, aims to compare the effects of two methods of teaching (virtual versus traditional) on student learning. This post-test only design study approached 40, fifth year dental students of Shiraz University of Medical Sciences. From this group, 35 students agreed to participate. These students were randomly allocated into two groups, experimental (virtual learning) and comparison (traditional learning). To ensure similarity between groups, we compared GPAs of all participants by the Mann-Whitney U test (P > 0.05). The experimental group received a virtual learning environment courseware package specifically designed for this study, whereas the control group received the same module structured in a traditional lecture form. The virtual learning environment consisted of online and offline materials. Two identical valid, reliable post-tests that consisted of 40 multiple choice questions (MCQs) and 4 essay questions were administered immediately (15 min) after the last session and two months later to assess for knowledge retention. Data were analyzed by SPSS version 20. A comparison of the mean knowledge score of both groups showed that virtual learning was more effective than traditional learning (effect size = 0.69). The newly designed virtual learning package is feasible and will result in more effective learning in comparison with lecture-based training. However further studies are needed to generalize the findings of this study.

Research examining long-term outcomes after childbirth performed with different techniques of caesarean section have been limited and do not provide information on morbidity and neuropathic pain. The study compares two groups of patients submitted to the 'Traditional' method using Pfannenstiel incision and patients submitted to the 'Misgav Ladach' method ≥ 5 years after the operation. We find better long-term postoperative results in the patients that were treated with the Misgav Ladach method compared with the Traditional method. The results were statistically better regarding the intensity of pain, presence of neuropathic and chronic pain and the level of satisfaction about cosmetic appearance of the scar.

2017-04-01

Electronic cigarettes (e-cigarettes) are increasingly used by US adolescents and may be a gateway to traditional cigarette use. We examine rates of both products by age and examine differences in age-varying rates by sex and race/ethnicity. Data are from the 2014 National Youth Tobacco Survey, a national sample of US middle and high school students (n=22.007); students ages 11-19 were included. Past 30-day e-cigarette and traditional cigarette use were examined as a function of age; sex and race/ethnicity were included as moderators. The age-varying association between e-cigarette and traditional cigarette use was also examined. Rates of e-cigarette use increase faster than traditional cigarette use from ages 13-16. Compared to females, males had higher rates of e-cigarette use from ages 14-17.5 and traditional cigarette use from ages 15-18. Between ages 12-14, more Hispanic adolescents used e-cigarettes compared to White or Black adolescents; after age 14 Hispanics and Whites reported similar rates, peaking at twice the rate for Blacks. Hispanic adolescents report greater traditional cigarette use versus Whites between ages 12-13, but lower rates between ages 15-18. E-cigarette use was strongly associated with traditional cigarette use, particularly during early adolescence [OR>40 before age 12]. Young Hispanic adolescents are at elevated risk for use of e-cigarettes and traditional cigarettes during early adolescence. During early adolescence, youth using e-cigarettes are more likely to smoke traditional cigarettes compared to youth not using e-cigarettes. The study of age-varying effects holds promise for advancing understanding of disparities in health risk behaviors. Copyright © 2016 Elsevier Ltd. All rights reserved.

Aims: To compare the performance of traditional methods to quantitative polymerase chain reaction (qPCR) for detecting five biological agents in large-volume drinking-water samples concentrated by ultrafiltration (UF). Methods and Results: Drinking-water samples (100 l) were seeded with Bacillus anthracis, Cryptospordium parvum, Francisella tularensis, Salmonella Typhi, and Vibrio cholerae and concentrated by UF. Recoveries by traditional methods were variable between samples and between some replicates; recoveries were not determined by qPCR. Francisella tularensis and V. cholerae were detected in all 14 samples after UF, B. anthracis was detected in 13, and C. parvum was detected in 9 out of 14 samples. Numbers found by qPCR after UF were significantly or nearly related to those found by traditional methods for all organisms except for C. parvum. A qPCR assay for S. Typhi was not available. Conclusions: qPCR can be used to rapidly detect biological agents after UF as well as traditional methods, but additional work is needed to improve qPCR assays for several biological agents, determine recoveries by qPCR, and expand the study to other areas. Significance and Impact of the Study: To our knowledge, this is the first study to compare the use of traditional and qPCR methods to detect biological agents in large-volume drinking-water samples. ?? 2009 The Society for Applied Microbiology.

2014-01-01

This study compared physiological, physical and technical demands of Battlezone, traditional cricket training and one-day matches. Data were initially collected from 11 amateur, male cricket players (age: 22.2 ± 3.3 year, height: 1.82 ± 0.06 m body mass: 80.4 ± 9.8 kg) during four Battlezone and four traditional cricket training sessions encompassing different playing positions. Heart rate, blood lactate concentration, rating of perceived exertion and movement patterns of players were measured. Retrospective video analysis was performed to code for technical outcomes. Similar data were collected from 42 amateur, male cricket players (23.5 ± 4.7 year, 1.81 ± 0.07 m, 81.4 ± 11.4 kg) during one-day matches. Significant differences were found between Battlezone, traditional cricket training and one-day matches within each playing position. Specifically, Battlezone invoked the greatest physiological and physical demands from batsmen in comparison to traditional cricket training and one-day matches. However, the greatest technical demand for batsmen was observed during traditional cricket training. In regards to the other playing positions, a greater physiological, physical and technical demand was observed during Battlezone and traditional training than during one-day matches. These results suggest that the use of Battlezone and traditional cricket training provides players with a suitable training stimulus for replicating the physiological, physical and technical demands of one-day cricket.

The aim of this study was to evaluate the capacity of a traditional stethoscope versus an electronically amplified one (expected to reduce background and ambient noise) to assess heart and respiratory sounds during medical transport. It was a prospective, double-blinded, randomized performed study. One traditional stethoscope (Littmann Cardiology III; 3M, St Paul, MN) and 1 electronically amplified stethoscope (Littmann 3200, 3M) were used for our tests. Heart and lung auscultation during real medical evacuations aboard a medically configured Falcon 50 aircrafts were studied. The quality of auscultation was ranged using a numeric rating scale from 0 to 10 (0 corresponding to "I hear nothing" and 10 to "I hear perfectly"). Data collected were compared using a t-test for paired values. A total of 40 comparative evaluations were performed. For cardiac auscultation, the value of the rating scale was 4.53 ± 1.91 and 7.18 ± 1.88 for the traditional and amplified stethoscope, respectively (paired t-test: P < .0001). For respiratory sounds, quality of auscultation was estimated at 3.1 ± 1.95 for a traditional stethoscope and 5.10 ± 2.13 for the amplified one (paired t-test: P < .0001). This study showed that practitioners would be better helped in hearing cardiac and respiratory sounds with an electronically amplified stethoscope than with a traditional one during air medical transport in a medically configured Falcon 50 aircraft.

This study assessed the potential therapeutic benefi t of using HandTutor™ in combination with traditional rehabilitation in a post-stroke sub-acute population. The study compares an experimental group receiving traditional therapy combined with HandTutorTM treatment, against a control group receiving only traditional therapy. An assessor-blinded, randomized controlled pilot trial, was conducted in the Reuth rehabilitation unit in Israel. Thirty-one stroke patients in the sub-acute phase, were randomly assigned to one of the two groups (experimental or control) in sets of three. The experimental group (n = 16) underwent a hand rehabilitation programme using the HandTutorTM combined with traditional therapy. The control group (n = 15) received only traditional therapy. The treatment schedules for both groups were of similar duration and frequency. Improvements were evaluated using three indicators: 1) The Brunnström-Fugl-Meyer (FM) test, 2) the Box and Blocks (B&B) test and 3) improvement parameters as determined by the HandTutorTM software. Following 15 consecutive treatment sessions, a signifi cant improvement was observed within the experimental group (95% confi dence intervals) compared with the control group: B&B p = 0.015; FM p = 0.041, HandTutor™ performance accuracy on x axis and performance accuracy on y axis p < 0.0003. The results from this pilot study support further investigation of the use of the HandTutorTM in combination with traditional occupational therapy and physiotherapy during post stroke hand function rehabilitation.

Liposomal bupivacaine is a novel method for pain control after total knee arthroplasty (TKA), but recent studies showed no advantage for patients undergoing TKA compared with traditional periarticular injection (PAI). The purpose of this analysis was to compare the clinical outcomes between liposomal bupivacaine treatment and traditional PAI. We retrospectively reviewed data from 16 clinical trials in published databases from their inception to June 2017. The primary outcome was postoperative Visual Analogue Scale (VAS) score and secondary outcomes included opiate usage, narcotic consumption, range of motion, and length of stay. Nine randomized controlled trials and seven nonrandomized controlled trials involving 924 liposomal bupivacaine cases and 1,293 traditional PAI cases were eligible for inclusion in the meta-analysis. No differences were detected in most of the clinical outcomes, except for postoperative VAS within 12 hours and length of stay. This analysis showed that liposomal bupivacaine is not associated with significant improvement in postoperative pain control or other outcomes in TKA compared with PAI.

Palappallil, Dhanya Sasidharan; Sushama, Jitha; Ramnath, Sai Nathan

2016-01-01

Context: Student-led seminars (SLS) are adopted as a teaching-learning (T-L) method in pharmacology. Previous studies assessing the feedback on T-L methods in pharmacology points out that the traditional seminars consistently received poor feedbacks as they were not favorite among the students. Aims: This study aimed to obtain feedback on traditional SLS, introduce modified SLS and compare the modified seminars with the traditional ones. Settings and Design: This was a prospective interventional study done for 2 months in medical undergraduates of fifth semester attending Pharmacology seminars at a Government Medical College in South India. Subjects and Methods: Structured questionnaire was used to elicit feedback from participants. The responses were coded on 5-point Likert scale. Modifications in seminar sessions such as role plays, quiz, tests, group discussion, and patient-oriented problem-solving exercises were introduced along with SLS. Statistical Analysis Used: The data were analyzed using SPSS version 16. The descriptive data were expressed using frequencies and percentages. Wilcoxon signed rank test, and Friedman tests were used to compare traditional with modified seminars. Results: The participants identified interaction as the most important component of a seminar. Majority opined that the teacher should summarize at the end of SLS. Student feedback shows that modified seminars created more interest, enthusiasm, and inspiration to learn the topic when compared to traditional SLS. They also increased peer coordination and group dynamics. Students opined that communication skills and teacher-student interactions were not improved with modified seminars. Conclusions: Interventions in the form of modified SLS may be adopted to break the monotony of traditional seminars through active participation, peer interaction, and teamwork. PMID:27563587

Walk-in counselling has been used to reduce wait times but there are few controlled studies to compare outcomes between walk-in and the traditional model of service delivery. To compare change in psychological distress by clients receiving services from two models of service delivery, a walk-in counselling model and a traditional counselling model involving a wait list. Mixed-methods sequential explanatory design including quantitative comparison of groups with one pre-test and two follow-ups, and qualitative analysis of interviews with a sub-sample. Five-hundred and twenty-four participants ≥16 years were recruited from two Family Counselling Agencies; the General Health Questionnaire-12 assessed change in psychological distress. Hierarchical linear modelling revealed clients of the walk-in model improved faster and were less distressed at the four-week follow-up compared to the traditional service delivery model. Ten weeks later, both groups had improved and were similar. Participants receiving instrumental services prior to baseline improved more slowly. The qualitative data confirmed participants highly valued the accessibility of the walk-in model, and were frustrated by the lengthy waits associated with the traditional model. This study improves methodologically on previous studies of walk-in counselling, an approach to service delivery not conducive to randomized controlled trials.

The primary purpose of this study was to compare two, shorter, self-directed methods of cardiopulmonary resuscitation (CPR) education for healthcare professionals (HCP) to traditional training with a focus on the trainee's ability to perform two-person CPR. First-year medical students with either no prior CPR for HCP experience or prior training greater than 5 years were randomized to complete one of three courses: 1) HeartCode BLS System, 2) BLS Anytime, or 3) Traditional training. Only data from the adult CPR skills testing station was reviewed via video recording by certified CPR instructors and the Laerdal PC Skill Reporter software program (Laerdal Medical, Stavanger, Norway). There were 180 first-year medical students who met inclusion criteria: 68 were HeartCode BLS System, 53 BLS Anytime group, and 59 traditional group Regarding two-person CPR, 57 (84%) of Heartcode BLS students and 43 (81%) of BLS Anytime students were able to initiate the switch compared to 39 (66%) of traditional course students (p = 0.04). There were no significant differences in the quality of chest compressions or ventilations between the three groups. There was a trend for a much higher CPR skills testing pass rate for the traditional course students. However, failure to "clear to analyze or shock" while using the AED was the most common reason for failure in all groups. The self-directed learning groups not only had a high level of success in initiating the "switch" to two-person CPR, but were not significantly different from students who completed traditional training.

The use of point-of-care (POC) devices within the home for routine INR monitoring has demonstrated reliability, safety and effectiveness in the management of infants and children requiring long-term warfarin therapy. However, a comprehensive cost-analysis of using this method of management, compared to attending anticoagulation clinics has not been reported. The aim of this study was to compare the estimated societal costs of attending anticoagulation clinics for routine INR monitoring to using a POC test in the home. This study used a comparative before-and-after design that included 60 infants and children managed via the Haematology department at a tertiary paediatric centre. Each participant was exposed to both modes of management at various times for a period of ≥3 months. A questionnaire, consisting of 25 questions was sent to families to complete and return. Data collected included: the frequency of monitoring, mode of travel to and from clinics, total time consumed, and primary carer's income level. The home monitoring cohort saved a total of 1 hour 19 minutes per INR test compared to attending anticoagulation clinics and had a cost saving to society of $66.83 (AUD) per INR test compared to traditional care; incorporating health sector costs, travel expenses and lost time. The traditional model of care requires a considerable investment of time per test from both child and carer. Home INR monitoring in infants and children provides greater societal economic benefits compared to traditional models. Copyright © 2013 Elsevier Ltd. All rights reserved.

Comparative studies evaluating traditional versus newer antianginal (AA) medications in chronic stable angina pectoris (CSA) on cardiovascular (CV) outcomes and utilization are limited, particularly in patients with diabetes mellitus (DM). Claims data (2008 to 2012) were analyzed using a commercial database. Patients with CSA receiving a β blocker (BB), calcium channel blocker (CCB), long-acting nitrate (LAN), or ranolazine were identified and followed for 12 months after a change in AA therapy. Patients on traditional AA medications were required to have concurrent sublingual nitroglycerin. Therapy change was defined as adding or switching to another traditional AA medication or ranolazine to identify patients whose angina was inadequately controlled with previous therapy. Four groups were identified (BB, CCB, LAN, or ranolazine users) and matched on relevant characteristics. A DM subset was identified. Logistic regression compared revascularization at 30, 60, 90, 180, and 360 days. Negative binomial regression compared all-cause, CV-, and DM-related (in the DM cohort) health care utilization. A total of 8,008 patients were identified with 2,002 patients in each matched group. Majority were men (mean age 66 years). A subset of 3,724 patients with DM (BB, n = 933; CCB, n = 940; LAN, n = 937; and ranolazine, n = 914) resulted from this cohort. Compared to ranolazine in the overall cohort, traditional AA medication exhibited greater odds for revascularization and higher rates in all-cause outpatient, emergency room visits, inpatient length of stay, and CV-related emergency room visits. In the DM cohort, ranolazine demonstrated similar benefits over traditional AA medication. In conclusion, ranolazine use in patients with inadequately controlled chronic angina is associated with less revascularization and all-cause and CV-related health care utilization compared to traditional AA medication.

Fusion of the lumbosacral spine is a common surgical procedure to address a range of spinal pathologies. Fixation in lumbar fusion has traditionally been performed using pedicle screw (PS) augmentation. However, an alternative method of screw insertion via cortical bone trajectory (CBT) has been advocated as a less invasive approach which improves initial fixation and reduces neurovascular injury. There is a paucity of robust clinical evidence to support these claims, particularly in comparison to traditional pedicle screws. This study aims to review the available evidence to assess the merits of the CBT approach. Six electronic databases were searched for original published studies which compared CBT with traditional PS and their findings reviewed. Nine comparative studies were identified through a comprehensive literature search. Studies were classified as retrospective cohort, prospective cohort or case control studies with medium quality as assessed by the GRADE criteria. The available literature is not cohesive regarding outcomes and complications of CBT versus PT procedures. Most studies found no difference in operative time, but reported less blood loss during CBT. Radiological outcomes show no difference in slippage at one year although CBT is associated with greater bone-density compared to PT. Results for post-operative pain are inconclusive.

The cognitive load (CL) theoretical framework suggests that working memory is limited, which has implications for learning and skills acquisition. Complex learning situations such as surgical skills training can potentially induce a cognitive overload, inhibiting learning. This study aims to compare CL in traditional cadaveric dissection training and virtual reality (VR) simulation training of mastoidectomy. A prospective, crossover study. Participants performed cadaveric dissection before VR simulation of the procedure or vice versa. CL was estimated by secondary-task reaction time testing at baseline and during the procedure in both training modalities. The national Danish temporal bone course. A total of 40 novice otorhinolaryngology residents. Reaction time was increased by 20% in VR simulation training and 55% in cadaveric dissection training of mastoidectomy compared with baseline measurements. Traditional dissection training increased CL significantly more than VR simulation training (p < 0.001). VR simulation training imposed a lower CL than traditional cadaveric dissection training of mastoidectomy. Learning complex surgical skills can be a challenge for the novice and mastoidectomy skills training could potentially be optimized by employing VR simulation training first because of the lower CL. Traditional dissection training could then be used to supplement skills training after basic competencies have been acquired in the VR simulation.

Rubinstein, Jack; Dhoble, Abhijeet; Ferenchick, Gary

2009-01-01

Background Most medical professionals are expected to possess basic electrocardiogram (EKG) interpretation skills. But, published data suggests that residents' and physicians' EKG interpretation skills are suboptimal. Learning styles differ among medical students; individualization of teaching methods has been shown to be viable and may result in improved learning. Puzzles have been shown to facilitate learning in a relaxed environment. The objective of this study was to assess efficacy of teaching puzzle in EKG interpretation skills among medical students. Methods This is a reader blinded crossover trial. Third year medical students from College of Human Medicine, Michigan State University participated in this study. Two groups (n = 9) received two traditional EKG interpretation skills lectures followed by a standardized exam and two extra sessions with the teaching puzzle and a different exam. Two other groups (n = 6) received identical courses and exams with the puzzle session first followed by the traditional teaching. EKG interpretation scores on final test were used as main outcome measure. Results The average score after only traditional teaching was 4.07 ± 2.08 while after only the puzzle session was 4.04 ± 2.36 (p = 0.97). The average improvement after the traditional session was followed up with a puzzle session was 2.53 ± 1.94 while the average improvement after the puzzle session was followed with the traditional session was 2.08 ± 1.73 (p = 0.67). The final EKG exam score for this cohort (n = 15) was 84.1 compared to 86.6 (p = 0.22) for a comparable sample of medical students (n = 15) at a different campus. Conclusion Teaching EKG interpretation with puzzles is comparable to traditional teaching and may be particularly useful for certain subgroups of students. Puzzle session are more interactive and relaxing, and warrant further investigations on larger scale. PMID:19144134

YOON, Ju Young; BROWN, Roger L.; BOWERS, Barbara J.; SHARKEY, Siobhan S.; HORN, Susan D.

2015-01-01

Background Growing attention in the past few decades has focused on improving care quality and quality of life for nursing home residents. Many traditional nursing homes have attempted to transform themselves to become more homelike emphasizing individualized care. This trend is referred to as nursing home culture change in the U.S. A promising culture change nursing home model, the Green House (GH) nursing home model, has shown positive psychological outcomes. However, little is known about whether the GH nursing home model has positive effects on physical function compared to traditional nursing homes. Objectives To examine the longitudinal effects of the GH nursing home model by comparing change patterns of ADL function over time between GH home residents and traditional nursing home residents. Design A retrospective longitudinal study. Settings Four GH organizations (nine GH units and four traditional units). Participants A total of 242 residents (93 GH residents and 149 traditional home residents) who had stayed in the nursing home at least six months from admission. Methods The outcome was ADL function, and the main independent variable was the facility type in which the resident stayed: a GH or traditional unit. Age, gender, comorbidity score, cognitive function, and depressive symptoms at baseline were controlled. All of these measures were from a minimum dataset. Growth curve modeling and growth mixture modeling were employed in this study for longitudinal analyses. Results The mean ADL function showed deterioration over time, and the rates of deterioration between GH and traditional home residents were not different over time. Four different ADL function trajectories were identified for 18 months, but there was no statistical difference in the likelihood of being in one of the four trajectory classes between the two groups. Conclusions Although GH nursing homes are considered to represent an innovative model changing the nursing home environment into more person-centered, this study did not demonstrate significant differences in ADL function changes for residents in the GH nursing homes compared to traditional nursing homes. Given that the GH model continues to evolve as it is being implemented and variations within and across GH homes are identified, large-scale longitudinal studies are needed to provide further relevant information on the effects of the GH model.

We study cardiovascular responses to emotional stresses in humans and rats using traditional physiological parameters and methods of nonlinear dynamics. We found that emotional stress results in significant changes of chaos degree of ECG and blood pressure signals, estimated using a normalized entropy. We demonstrate that the normalized entropy is a more sensitive indicator of the stress-induced changes in cardiovascular systems compared with traditional physiological parameters Using the normalized entropy we discovered the significant individual differences in cardiovascular stress-reactivity that was impossible to obtain by traditional physiological methods.

Currently, there are three algorithms for screening of syphilis: traditional algorithm, reverse algorithm and European Centre for Disease Prevention and Control (ECDC) algorithm. To date, there is not a generally recognized diagnostic algorithm. When syphilis meets HIV, the situation is even more complex. To evaluate their screening performance and impact on the seroprevalence of syphilis in HIV-infected individuals, we conducted a cross-sectional study included 865 serum samples from HIV-infected patients in a tertiary hospital. Every sample (one per patient) was tested with toluidine red unheated serum test (TRUST), T. pallidum particle agglutination assay (TPPA), and Treponema pallidum enzyme immunoassay (TP-EIA) according to the manufacturer's instructions. The results of syphilis serological testing were interpreted following different algorithms respectively. We directly compared the traditional syphilis screening algorithm with the reverse syphilis screening algorithm in this unique population. The reverse algorithm achieved remarkable higher seroprevalence of syphilis than the traditional algorithm (24.9% vs. 14.2%, p < 0.0001). Compared to the reverse algorithm, the traditional algorithm also had a missed serodiagnosis rate of 42.8%. The total percentages of agreement and corresponding kappa values of tradition and ECDC algorithm compared with those of reverse algorithm were as follows: 89.4%,0.668; 99.8%, 0.994. There was a very good strength of agreement between the reverse and the ECDC algorithm. Our results supported the reverse (or ECDC) algorithm in screening of syphilis in HIV-infected populations. In addition, our study demonstrated that screening of HIV-populations using different algorithms may result in a statistically different seroprevalence of syphilis.

Investigators have hypothesised that piezoelectric surgical device could permanently replace traditional saws in conventional orthognathic surgery. Twelve consecutive patients who underwent bimaxillary procedures were involved in the study. In six patients the right maxillary and mandible osteotomies were performed using traditional saw, whilst the left osteotomies by piezoosteotomy; in the remaining six patients, the surgical procedures were reversed. Intraoperative blood loss, procedure duration time, incision precision, postoperative swelling and haematoma, and nerve impairment were evaluated to compare the outcomes and costs of these two procedures. Compare to traditional mechanical surgery, piezoosteotomy showed a significant intraoperative blood loss reduction of 25% (p = 0.0367), but the mean surgical procedure duration was longer by 35% (p = 0.0018). Moreover, the use of piezoosteotomy for mandible procedure required more time than for the maxillary surgery (p = 0.0003). There was a lower incidence of postoperative haematoma and swelling following piezoosteotomy, and a statistically significant reduction in postoperative nerve impairment (p = 0.003). We believe that piezoelectric device allows surgeons to achieve better results compared to a traditional surgical saw, especially in terms of intraoperative blood loss, postoperative swelling and nerve impairment. This device represents a less aggressive and safer method to perform invasive surgical procedures such as a Le Fort I osteotomy. However, we recommend the use of traditional saw in mandible surgery because it provides more foreseeable outcomes and well-controlled osteotomy. Further studies are needed to analyse whether piezoosteotomy could prevent relapse and promote bony union in larger advancements.

Circumferential finger measurements utilizing a torque meter to increase reliability.

PubMed

King, T I

1993-01-01

The purpose of this study was to compare the reliabilities of two methods of measuring finger circumference. Traditionally, finger circumference is determined clinically by the use of a tape measure. In this study, a tape-measure device for recording finger circumference utilizing a torque meter was compared with the traditional method to determine reliability differences. Ninety-two occupational therapists and occupational therapy students obtained circumferential measurements of the author's left index finger at the middle of the proximal phalanx utilizing the two methods. The readings obtained for each method were analyzed to determine the coefficient of variation and to compare their variances. The coefficient of variation for the traditional method was 2.92 and for the device utilizing the torque meter was 0.75. The F ratio was 15.63, which is significant at the 0.01 level. The results of this study indicate greater interrater reliability using a device that can accurately measure torque and allow the therapist to control the amount of tension applied when obtaining circumferential measurements using a tape measure.

The purpose of this study was to compare the acute effects of static stretching; dynamic exercises and high volume upper extremity plyometric activity on tennis serve performance. Twenty-six elite young tennis players (15.1 ± 4.2 years, 167.9 ± 5.8 cm and 61.6 ± 8.1 kg) performed 4 different warm-up (WU) routines in a random order on non-consecutive days. The WU methods consisted of traditional WU (jogging, rally and serve practice) (TRAD); traditional WU and static stretching (TRSS); traditional WU and dynamic exercise (TRDE); and traditional WU and high volume upper extremity plyometric activity (TRPLYP). Following each WU session, subjects were tested on a tennis serve ball speed test. TRAD, TRSS, TRDE and TRPLYO were compared by repeated measurement analyses of variance and post-hoc comparisons. In this study a 1 to 3 percent increase in tennis serve ball speed was recorded in TRDE and TRPLYO when compared to TRAD (p< 0.05). However, no significant change in ball speed performance between TRSS and TRAD. (p> 0.05). ICCs for ball speed showed strong reliability (0.82 to 0.93) for the ball speed measurements.The results of this study indicate that dynamic and high volume upper extremity plyometric WU activities are likely beneficial to serve speed of elite junior tennis players. Key points After the traditional warm up in tennis, static stretching has no effect on serve speed. Tennis players should perform dynamic exercises and/or high volume upper extremity plyometric activities to improve their athletic performance. PMID:24150068

Recent developments in computer and video technology, multimedia resources enter quickest way possible into medical education and have started to gain popularity. The aim of this study is to evaluate the impact of video-supported lectures on leaning, with comparison to traditional lectures. According to lecture techniques, two separate groups; one is the traditional lectures group (TLG) and the other is video-supported lectures group (VSLG), are formed. While the TLG is offered a traditional lecture the VSLG is offered a video-supported lecture with imbedded videos which are related to the topics in the traditional lecture. Both study groups take pretest and posttest with MCQs (multiple choice questions) and OSCEs (objective structured clinical examination). The study includes 30 volunteer residents in Dokuz Eylul University School of Medicine Department of Emergency Medicine. No difference is observed between TGL and VSLG in pretest and posttest scores (p = 0.949, p = 0.580). And additionally, comparing the scores of both groups, we cannot observe any difference between the pretest OSCE scores of each group (p = 0.300), however posttest OSCE scores shows a dramatic odd in-between (p = 0.010). When pretest MCQs and posttest MCQs mean scores are compared, both tests (TLG, VSLG) has not any significant difference (p=0.949, p = 0.580). Nevertheless, after comparing OSCEs pretest and posttest mean scores, we can see significant difference in mean scores of both (TLG, VSLG), (p = 0.011, p = 0.001). Taken into consideration, the findings of this study shows possibility of improving educational techniques to acquire clinical skills by using local resources and low-cost technology.

Robotic bariatric surgery: a systematic review.

PubMed

Fourman, Matthew M; Saber, Alan A

2012-01-01

Obesity is a nationwide epidemic, and the only evidence-based, durable treatment of this disease is bariatric surgery. This field has evolved drastically during the past decade. One of the latest advances has been the increased use of robotics within this field. The goal of our study was to perform a systematic review of the recent data to determine the safety and efficacy of robotic bariatric surgery. The setting was the University Hospitals Case Medical Center (Cleveland, OH). A PubMed search was performed for robotic bariatric surgery from 2005 to 2011. The inclusion criteria were English language, original research, human, and bariatric surgical procedures. Perioperative data were then collected from each study and recorded. A total of 18 studies were included in our review. The results of our systematic review showed that bariatric surgery, when performed with the use of robotics, had similar or lower complication rates compared with traditional laparoscopy. Two studies showed shorter operative times using the robot for Roux-en-Y gastric bypass, but 4 studies showed longer operative times in the robotic arm. In addition, the learning curve appears to be shorter when robotic gastric bypass is compared with the traditional laparoscopic approach. Most investigators agreed that robotic laparoscopic surgery provides superior imaging and freedom of movement compared with traditional laparoscopy. The application of robotics appears to be a safe option within the realm of bariatric surgery. Prospective randomized trials comparing robotic and laparoscopic outcomes are needed to further define the role of robotics within the field of bariatric surgery. Longer follow-up times would also help elucidate any long-term outcomes differences with the use of robotics versus traditional laparoscopy.

Hew, Khe Foon; Lo, Chung Kwan

2018-03-15

The use of flipped classroom approach has become increasingly popular in health professions education. However, no meta-analysis has been published that specifically examines the effect of flipped classroom versus traditional classroom on student learning. This study examined the findings of comparative articles through a meta-analysis in order to summarize the overall effects of teaching with the flipped classroom approach. We focused specifically on a set of flipped classroom studies in which pre-recorded videos were provided before face-to-face class meetings. These comparative articles focused on health care professionals including medical students, residents, doctors, nurses, or learners in other health care professions and disciplines (e.g., dental, pharmacy, environmental or occupational health). Using predefined study eligibility criteria, seven electronic databases were searched in mid-April 2017 for relevant articles. Methodological quality was graded using the Medical Education Research Study Quality Instrument (MERSQI). Effect sizes, heterogeneity estimates, analysis of possible moderators, and publication bias were computed using the COMPREHENSIVE META-ANALYSIS software. A meta-analysis of 28 eligible comparative studies (between-subject design) showed an overall significant effect in favor of flipped classrooms over traditional classrooms for health professions education (standardized mean difference, SMD = 0.33, 95% confidence interval, CI = 0.21-0.46, p < 0.001), with no evidence of publication bias. In addition, the flipped classroom approach was more effective when instructors used quizzes at the start of each in-class session. More respondents reported they preferred flipped to traditional classrooms. Current evidence suggests that the flipped classroom approach in health professions education yields a significant improvement in student learning compared with traditional teaching methods.

A comparative study of traditional lecture methods and interactive lecture methods in introductory geology courses for non-science majors at the college level

NASA Astrophysics Data System (ADS)

Hundley, Stacey A.

In recent years there has been a national call for reform in undergraduate science education. The goal of this reform movement in science education is to develop ways to improve undergraduate student learning with an emphasis on developing more effective teaching practices. Introductory science courses at the college level are generally taught using a traditional lecture format. Recent studies have shown incorporating active learning strategies within the traditional lecture classroom has positive effects on student outcomes. This study focuses on incorporating interactive teaching methods into the traditional lecture classroom to enhance student learning for non-science majors enrolled in introductory geology courses at a private university. Students' experience and instructional preferences regarding introductory geology courses were identified from survey data analysis. The information gained from responses to the questionnaire was utilized to develop an interactive lecture introductory geology course for non-science majors. Student outcomes were examined in introductory geology courses based on two teaching methods: interactive lecture and traditional lecture. There were no significant statistical differences between the groups based on the student outcomes and teaching methods. Incorporating interactive lecture methods did not statistically improve student outcomes when compared to traditional lecture teaching methods. However, the responses to the survey revealed students have a preference for introductory geology courses taught with lecture and instructor-led discussions and students prefer to work independently or in small groups. The results of this study are useful to individuals who teach introductory geology courses and individuals who teach introductory science courses for non-science majors at the college level.

In this article, we examine how American Indian students in Montana performed on standardized state science assessments when a small number of test items based upon traditional science knowledge from a cultural curriculum, "Indian Education for All", were included. Montana is the first state in the US to mandate the use of a culturally relevant curriculum in all schools and to incorporate this curriculum into a portion of the standardized assessment items. This study compares White and American Indian student test scores on these particular test items to determine how White and American Indian students perform on culturally relevant test items compared to traditional standard science test items. The connections between student achievement on adapted culturally relevant science test items versus traditional items brings valuable insights to the fields of science education, research on student assessments, and Indigenous studies.

NeuroQuant® is a recently developed, FDA-approved software program for measuring brain MRI volume in clinical settings. The purpose of this study was to compare NeuroQuant with the radiologist's traditional approach, based on visual inspection, in 20 outpatients with mild or moderate traumatic brain injury (TBI). Each MRI was analyzed with NeuroQuant, and the resulting volumetric analyses were compared with the attending radiologist's interpretation. The radiologist's traditional approach found atrophy in 10.0% of patients; NeuroQuant found atrophy in 50.0% of patients. NeuroQuant was more sensitive for detecting brain atrophy than the traditional radiologist's approach.

Despite the proven efficacy of cardiopulmonary resuscitation (CPR), only a small fraction of the population knows how to perform it. As a result, rates of bystander CPR and rates of survival from cardiac arrest are low. Bystander CPR is particularly uncommon in the African American community. Successful development of a simplified approach to CPR training could boost rates of bystander CPR and save lives. We conducted the following randomized, controlled study to determine whether video self-instruction (VSI) in CPR results in comparable or better performance than traditional CPR training. This randomized, controlled trial was conducted among congregational volunteers in an African American church in Atlanta, GA. Subjects were randomly assigned to receive either 34 minutes of VSI or the 4-hour American Heart Association "Heartsaver" CPR course. Two months after training, blinded observers used explicit criteria to assess CPR performance in a simulated cardiac arrest setting. A recording manikin was used to measure ventilation and chest compression characteristics. Participants also completed a written test of CPR-related knowledge and attitudes. VSI trainees displayed a comparable level of performance to that achieved by traditional trainees. Observers scored 40% of VSI trainees competent or better in performing CPR, compared with only 16% of traditional trainees (absolute difference 24%, 95% confidence interval 8% to 40%). Data from the recording manikin confirmed these observations. VSI trainees and traditional trainees achieved comparable scores on tests of CPR-related knowledge and attitudes. Thirty-four minutes of VSI can produce CPR of comparable quality to that achieved by traditional training methods. VSI provides a simple, quick, consistent, and inexpensive alternative to traditional CPR instruction, and may be used to extend CPR training to historically underserved populations.

Effect of Minimalist Footwear on Running Efficiency

Gillinov, Stephen M.; Laux, Sara; Kuivila, Thomas; Hass, Daniel; Joy, Susan M.

2015-01-01

Background: Although minimalist footwear is increasingly popular among runners, claims that minimalist footwear enhances running biomechanics and efficiency are controversial. Hypothesis: Minimalist and barefoot conditions improve running efficiency when compared with traditional running shoes. Study Design: Randomized crossover trial. Level of Evidence: Level 3. Methods: Fifteen experienced runners each completed three 90-second running trials on a treadmill, each trial performed in a different type of footwear: traditional running shoes with a heavily cushioned heel, minimalist running shoes with minimal heel cushioning, and barefoot (socked). High-speed photography was used to determine foot strike, ground contact time, knee angle, and stride cadence with each footwear type. Results: Runners had more rearfoot strikes in traditional shoes (87%) compared with minimalist shoes (67%) and socked (40%) (P = 0.03). Ground contact time was longest in traditional shoes (265.9 ± 10.9 ms) when compared with minimalist shoes (253.4 ± 11.2 ms) and socked (250.6 ± 16.2 ms) (P = 0.005). There was no difference between groups with respect to knee angle (P = 0.37) or stride cadence (P = 0.20). When comparing running socked to running with minimalist running shoes, there were no differences in measures of running efficiency. Conclusion: When compared with running in traditional, cushioned shoes, both barefoot (socked) running and minimalist running shoes produce greater running efficiency in some experienced runners, with a greater tendency toward a midfoot or forefoot strike and a shorter ground contact time. Minimalist shoes closely approximate socked running in the 4 measurements performed. Clinical Relevance: With regard to running efficiency and biomechanics, in some runners, barefoot (socked) and minimalist footwear are preferable to traditional running shoes. PMID:26131304

Healing in the Sámi North

Stabbursvik, Ellen Anne Buljo

2010-01-01

There is a special emphasis today on integrating traditional healing within health services. However, most areas in which there is a system of traditional healing have undergone colonization and a number of pressures suppressing tradition for hundreds of years. The question arises as to how one can understand today’s tradition in light of earlier traditions. This article is based on material collected in Sámi areas of Finnmark and Nord-Troms Norway; it compares local healing traditions with what is known of earlier shamanic traditions in the area. The study is based on 27 interviews among healers and their patients. The findings suggest that although local healing traditions among the Sámi in northern Norway have undergone major transformations during the last several hundred years, they may be considered an extension of a long-standing tradition with deep roots in the region. Of special interest are also the new forms tradition may take in today’s changing global society. PMID:20862528

Portillo, María Priscilla; Rojas, Sandra; Guzman, Marco; Quezada, Camilo

2018-03-01

The present study aimed to observe whether physiological warm-up and traditional singing warm-up differently affect aerodynamic, electroglottographic, acoustic, and self-perceived parameters of voice in Contemporary Commercial Music singers. Thirty subjects were asked to perform a 15-minute session of vocal warm-up. They were randomly assigned to one of two types of vocal warm-up: physiological (based on semi-occluded exercises) or traditional (singing warm-up based on open vowel [a:]). Aerodynamic, electroglottographic, acoustic, and self-perceived voice quality assessments were carried out before (pre) and after (post) warm-up. No significant differences were found when comparing both types of vocal warm-up methods, either in subjective or in objective measures. Furthermore, the main positive effect observed in both groups when comparing pre and post conditions was a better self-reported quality of voice. Additionally, significant differences were observed for sound pressure level (decrease), glottal airflow (increase), and aerodynamic efficiency (decrease) in the traditional warm-up group. Both traditional and physiological warm-ups produce favorable voice sensations. Moreover, there are no evident differences in aerodynamic and electroglottographic variables when comparing both types of vocal warm-ups. Some changes after traditional warm-up (decreased intensity, increased airflow, and decreased aerodynamic efficiency) could imply an early stage of vocal fatigue.

To the software design community, the concern over the costs associated with a program's execution time and implementation is great. It is always desirable, and sometimes imperative, that the proper programming technique is chosen which minimizes all costs for a given application or type of application. A study is described that compared cost-related factors associated with traditional programming techniques to rule-based programming techniques for a specific application. The results of this study favored the traditional approach regarding execution efficiency, but favored the rule-based approach regarding programmer productivity (implementation ease). Although this study examined a specific application, the results should be widely applicable.

Any curriculum change is essentially an environmental change; therefore there is a need to assess the impact of any change in the curriculum on the students' perception of the Educational Environment (EE) and psychological well-being. The objectives of the current study are to (i) compare the EE perceptions of medical students studying in a System Based Curriculum (SBC) with those studying in a traditional curriculum (ii) compare the rate of depressive symptoms among the same students studying in both types of curricula (iii) determine whether there is a difference in the EE perception and depressive symptoms based on gender and year of study. A cross sectional survey was conducted in a Saudi Medical School from 2007-2011, a period in which the school transitioned from a traditional to a SBC. A bilingual version of the Dundee Ready Educational Environment Measure (DREEM) inventory was used for measuring the EE; the Beck Depression Inventory (BDI II) was used for screening of depressive symptoms. A separate demographic questionnaire was also used. Mean scores and percentages were calculated. Continuous variables were summarized as means and standard deviation. For comparison of means, the effect size and student t test (with significance level of <0.05) were used. The percentages of the categorical data were compared using chi square test. The mean total DREEM score of positive perception of the EE in the SBC students was significantly higher (better) than the traditional curriculum students (p < 0.01) with an effect size of 0.472. The mean total score on the BDI-II inventory for depressive symptoms was higher (sicker) 21.3 among the female traditional curriculum students than 16.7 among the male traditional curriculum students and the difference was statistically significant (p = 0.001). The BDI score of the female SBC students (14.7) was significantly lower (healthier) than the female traditional curriculum students (21.3). No similar change was noted for the male students. The current study adds to the advantages of the SBC indicating not only healthier EE for both genders but also healthier emotional well-being for female students only.

Men die by suicide three to four times more often than women in Western countries. The adverse impact of the traditional male gender role as well as men's reluctance to seek help are possible explanations of this gender gap, but these hypotheses have not been well documented empirically. This study compares two groups of men who experienced comparable severely stressful life events during the preceding 12 months: 40 men admitted to hospital emergency following suicide attempts, and 40 men with no history of suicide attempts. Structured interviews were conducted to measure adherence to the traditional male gender role, help seeking behaviour, social support, suicide acceptability and mental health. ANOVAS indicated that attempters are more likely to adhere to the traditional masculine gender role and regression analysis revealed that this relationship persists even when the presence of mental disorders is statistically controlled. Sequential regression analysis support the mediation model and show that the effects of the traditional male gender role on suicidal behavior are mediated through protective and risk factors for suicide, namely mental state, help seeking and social support. The traditional male gender role appears to increase the risk of suicidal behavior in men by undermining their mental state and by inhibiting the protective factors of help seeking and social support. This study underscores the importance of encouraging men to seek help.

Traditional Chinese medicine is one of the popular alternative treatments for cancer, mainly enhancing host immune response and reducing adverse effect of chemotherapy. This study first explored traditional Chinese medicine treatment effect on long-term survival of lung cancer patients. This study evaluated whether traditional Chinese medicine combined with conventional cancer treatment improved overall survival of lung cancer patients. We had conducted a retrospective cohort study on 111,564 newly diagnosed lung cancer patients in 2000-2009 from National Health Insurance Program database. A total of 23,803 (21.31%) patients used traditional Chinese medicine for lung cancer care. Eligible participants were followed up until 2011 with a mean follow-up period of 1.96 years (standard deviation 2.55) for non-TCM users and 3.04 years (2.85) for traditional Chinese medicine users. Patients with traditional Chinese medicine utilization were significantly more likely to have a 32% decreased risk of death [hazard ratio = 0.62; 95% confidence interval = 0.61-0.63], compared with patients without traditional Chinese medicine utilization after multivariate adjustment. We also observed a similar significant reduction risk across various subgroups of chronic lung diseases. Qing Zao Jiu Fei Tang was the most effective traditional Chinese medicine agent for mortality reduction both in the entire lung cancer (0.81; 0.72-0.91) and matched populations (0.86; 0.78-0.95). This study demonstrated adjunctive therapy with traditional Chinese medicine may improve overall survival of lung cancer patients. This study also suggested traditional Chinese medicine may be used as an adjunctive therapy for cancer treatment. These observational findings need being validated by future randomized controlled trials to rule out the possibility of effect due to holistic care.

ABSTRACT Objective: to identify and synthesize the evidence from randomized clinical trials that tested the effectiveness of traditional Chinese acupuncture in relation to sham acupuncture for the treatment of hot flashes in menopausal women with breast cancer. Method: systematic review guided by the recommendations of the Cochrane Collaboration. Citations were searched in the following databases: MEDLINE via PubMed, Web of Science, CENTRAL, CINAHL, and LILACS. A combination of the following keywords was used: breast neoplasm, acupuncture, acupuncture therapy, acupuncture points, placebos, sham treatment, hot flashes, hot flushes, menopause, climacteric, and vasomotor symptoms. Results: a total of 272 studies were identified, five of which were selected and analyzed. Slight superiority of traditional acupuncture compared with sham acupuncture was observed; however, there were no strong statistical associations. Conclusions: the evidence gathered was not sufficient to affirm the effectiveness of traditional acupuncture compared with sham acupuncture. PMID:27533271

Background: Alzheimer’s disease (AD) is a progressive neurodegenerative disease with a high prevalence in recent years. Dramatic growth in AD prevalence has increased the importance of more researches on AD treatment. History has shown that traditional medicine can be a source of inspiration to find new therapies. Objectives: This study tried to codify the recommendations of Iranian traditional medicine (ITM) by studying the main medical manuscripts. The second purpose was to compare these findings with new medical information. Materials and Methods: Cardinal traditional medical and pharmacological texts from 10th to 18th century were searched for traditional terms of dementia (Nesyan, Fisad-uz-Zekr, Faramooshkari) focused on treatment methods. The findings were classified into three groups: lifestyle recommendations, dietary approaches, and drug therapies. These findings were compared with new medical findings. Results: ITM has dietary recommendations for dementia such as increasing consumption of nuts, poultry and eggs, milk, and grape products (like raisin and currant). These compounds are full of unsaturated fatty acids, cholesterol, and polyphenolic compounds. New findings suggest that these substances can help in prevention and treatment of AD. ITM has some lifestyle considerations like increasing physical and mental activities, listening to music, attending musical feasts, and smelling specific perfumes. New medical findings confirm nearly all of these recommendations. Along with the aforementioned items, treatment with natural medicines is in the first line of traditional treatment of dementia. New investigations show that many of these herbs have antioxidant, anti-inflammatory factors and acetylcholine esterase inhibitory effects. A few of them also have N-methyl-D-aspartate (NMDA) blocking activity. When these herbs are put together in traditional formulations, they can comprehensively fight against the disease. Conclusions: More ethnopharmacological and ethnomedical studies on ITM antidementia therapy can be followed by fruitful results. PMID:25763264

This study investigated the use of a Web-based community health simulation as a problem-based learning (PBL) experience for undergraduate students majoring in public health. The study sought to determine whether students who participated in the online simulation achieved differences in academic and attitudinal outcomes compared with students who participated in a traditional PBL exercise. Using a nonexperimental comparative design, 21 undergraduate students enrolled in a health-behavior course were each randomly assigned to one of four workgroups. Each workgroup was randomly assigned the semester-long simulation project or the traditional PBL exercise. Survey instruments were used to measure students' attitudes toward the course, their perceptions of the learning community, and perceptions of their own cognitive learning. Content analysis of final essay exams and group reports was used to identify differences in academic outcomes and students' level of conceptual understanding of health-behavior theory. Findings indicated that students participating in the simulation produced higher mean final exam scores compared with students participating in the traditional PBL (p=0.03). Students in the simulation group also outperformed students in the traditional group with respect to their understanding of health-behavior theory (p=0.04). Students in the simulation group, however, rated their own level of cognitive learning lower than did students in the traditional group (p=0.03). By bridging time and distance constraints of the traditional classroom setting, an online simulation may be an effective PBL approach for public health students. Recommendations include further research using a larger sample to explore students' perceptions of learning when participating in simulated real-world activities. Additional research focusing on possible differences between actual and perceived learning relative to PBL methods and student workgroup dynamics is also recommended.

To compare ophthalmology teaching delivered by eLearning with traditional lectures, in terms of undergraduate performance and satisfaction. Randomised controlled crossover study at King's College London Medical School with 245 third year medical students. The ophthalmology syllabus was divided into ten topics. Five topics were randomised to be taught by traditional lectures and five by electronic learning (eLearning). For the second rotation of students the topics were crossed over, so that those topics taught by traditional lectures were taught by eLearning and vice versa. At the end of each rotation the students sat an optional online mock examination containing 100 questions (ten on each topic). Students' examination performance was compared between the two teaching methods. Student satisfaction was assessed using an online satisfaction survey. Outcome measures were the mean percentage of correct answers across all ten topics, student satisfaction and self-assessed knowledge. The mean examination score for questions taught by eLearning was 58% (95% CI, 55.7-59.6), versus 55% (95% CI 53.1-56.8) for traditional lectures (P = 0.047). Across all topics students were more satisfied with eLearning than traditional lectures, with 87% (95% CI 84.5-88.4) rating eLearning as 'excellent' or 'good' versus 65% (95% CI 62.0-67.4) for lectures (p < 0.0001). Overall 180 (75.6%) preferred eLearning compared to traditional lectures, with 166 (69.7%) rating eLearning 'much better' or 'better,' 61 (25.6%) 'neutral' and 11 (4.6%) 'worse' or 'much worse.' Student satisfaction and examination performance are both enhanced by ophthalmology eLearning. Similar eLearning modules may be suitable for other specialties and postgraduate learning.

Traditional monitoring of blood pressure in hypertensive pregnant women requires frequent visits to the maternity outpatient services. Home blood-pressure monitoring (HBPM) could offer a cost-saving alternative that is acceptable to patients. The main objective of this study was to undertake a health economic analysis of HBPM compared with traditional monitoring in hypertensive pregnant women. This was a case-control study. Cases were pregnant women with hypertension who had HBPM with or without the adjunct of a smartphone app, via a specially designed pathway. The control group were managed as per existing hospital guidelines. Specific outcome measures were the number of outpatient visits, inpatient bed stays and investigations performed. Maternal, fetal and neonatal adverse outcomes were also recorded. Health economic analysis was performed using two methods: direct cost comparison of the study dataset and process scenario modelling. There were 108 women in the HBPM group, of whom 29 recorded their results on the smartphone app (App-HBPM) and 79 in their notes (Non-app HBPM). The control group comprised of 58 patients. There were significantly more women with chronic hypertension in the HBPM group (49.1% vs 25.9%, P = 0.004). The HBPM group had significantly longer duration of monitoring (9 weeks vs 5 weeks P = 0.004) and started monitoring from an earlier gestation (30 weeks vs 33.6 weeks, P = 0.001). Despite these differences, the mean saving per week for HBPM compared with the control group was £200.69. For the App-HBPM cohort, the saving per week compared with the control group was £286.53. The process modelling method predicted savings of between £98.32 and £245.80 per week using HBPM compared to the traditional monitoring. HBPM in hypertensive pregnancies appears to be cost-saving compared with traditional monitoring, without compromising maternal, fetal or neonatal safety. Larger studies are required to confirm these findings. This article is protected by copyright. All rights reserved.

The comparative study of the chemical composition and biological values of beef produced by hybrids of Angus cattle with wild yaks (hybrid beef) and pure-bred Angus cattle (traditional beef) has been carried out. Longissimus muscle samples were used for analysis. It was observed, that the hybrid beef samples had the practically equal protein content comparing to traditional beef (21.1 vs. 21.6 per cent) but were characterized by the lower fat content (1.2 vs. 2.5 per cent). The higher biological value of hybrid beef comparing to traditional beef has been shown. The value of protein-quality index, calculated as the ratio of tryptophan amino acid to oxyprolin and characterizing the ratio of high biological value proteins to low biological value proteins was 8.1 vs. 5.7. The values of amino acid indexes [ratio of essential amino acids (EAA) to non-essential amino acids (NAA) and ratio of EAA to the total amount of amino acids (TAA)] were EAA/NAA = 0.77 vs. 0.65 and EAA/TAA = 0.43 vs. 0.39. The protein of hybrid beef was characterized by the higher content of a number of the essential amino acids: by a factor of 1, 77 for threonin, 1.23--for valin, 1.09--for lysin, 1.17--for leucine and 1.19--for tryptophan. The amount of the essential amino acids in 1 gram of protein of the hybrid beef was 434.7 mg against 393.1 mg for traditional beef It has been shown, that the protein of the hybrid beef comparing to traditional beef is characterized by the higher values of the amino acid scores calculated for EAA.

Comparing two methods of education (virtual versus traditional) on learning of Iranian dental students: a post-test only design study

PubMed Central

2014-01-01

Background The importance of using technologies such as e-learning in different disciplines is discussed in the literature. Researchers have measured the effectiveness of e-learning in a number of fields. Considering the lack of research on the effectiveness of online learning in dental education particularly in Iran, the advantages of these learning methods and the positive university atmosphere regarding the use of online learning. This study, therefore, aims to compare the effects of two methods of teaching (virtual versus traditional) on student learning. Methods This post-test only design study approached 40, fifth year dental students of Shiraz University of Medical Sciences. From this group, 35 students agreed to participate. These students were randomly allocated into two groups, experimental (virtual learning) and comparison (traditional learning). To ensure similarity between groups, we compared GPAs of all participants by the Mann–Whitney U test (P > 0.05). The experimental group received a virtual learning environment courseware package specifically designed for this study, whereas the control group received the same module structured in a traditional lecture form. The virtual learning environment consisted of online and offline materials. Two identical valid, reliable post-tests that consisted of 40 multiple choice questions (MCQs) and 4 essay questions were administered immediately (15 min) after the last session and two months later to assess for knowledge retention. Data were analyzed by SPSS version 20. Results A comparison of the mean knowledge score of both groups showed that virtual learning was more effective than traditional learning (effect size = 0.69). Conclusion The newly designed virtual learning package is feasible and will result in more effective learning in comparison with lecture-based training. However further studies are needed to generalize the findings of this study. PMID:24597923

The purpose of this study was to compare the costs of traditional laparoscopy and robotic-assisted laparoscopy in the treatment of endometrial cancer. A total of 101 patients with endometrial cancer were randomized to the study and operated on starting from 2010 until 2013, at the Department of Obstetrics and Gynecology of Tampere University Hospital, Tampere, Finland. Costs were calculated based on internal accounting, hospital database, and purchase prices and were compared using intention-to-treat analysis. Main outcome measures were item costs and total costs related to the operation, including a 6-month postoperative follow-up. The total costs including late complications were 2160 &OV0556; higher in the robotic group (median for traditional 5823 &OV0556;, vs robot median 7983 &OV0556;, P < 0.001). The difference was due to higher costs for instruments and equipment as well as to more expensive operating room and postanesthesia care unit time. Traditional laparoscopy involved higher costs for operation personnel, general costs, medication used in the operation, and surgeon, although these costs were not substantial. There was no significant difference in in-patient stay, laboratory, radiology, blood products, or costs related to complications. According to this study, robotic-assisted laparoscopy is 37% more expensive than traditional laparoscopy in the treatment of endometrial cancer. The cost difference is mainly explained by amortization of the robot and its instrumentation.

This study aimed to assess knowledge and skills in a respiratory physiology course in traditional versus problem-based learning (PBL) groups in two different medical schools. Two different undergraduate medical schools were selected for this study. The first medical school followed the traditional [lecture-based learning (LBL)] curriculum, and the second medical school followed the PBL curriculum. Sixty first-year male medical students (30 students from each medical school) volunteered; they were apparently healthy and of the same age, sex, nationality, and regional and cultural background. Students were taught respiratory physiology according to their curriculum for a period of 2 wk. At the completion of the study period, knowledge was measured based on a single best multiple-choice question examination, and skill was measured based on the objective structured practical examination in the lung function laboratory (respiratory physiology). A Student's t-test was applied for the analysis of the data, and the level of significance was set at P < 0.05. Students belonging to the PBL curriculum obtained a higher score in the multiple-choice question examination (P = 0.001) and objective structured practical examination (P = 0.0001) compared with traditional (LBL) students. Students in the PBL group obtained significantly higher knowledge and skill scores in the respiratory physiology course compared with students in the traditional (LBL) style of medical schools.

Gallagher, Judith E; Dobrosielski-Vergona, Kathleen A; Wingard, Robin G; Williams, Theresa M

2005-01-01

Numerous studies have documented comparable outcomes from Web-based and traditional classroom instruction. However, there is a paucity of literature comparing these two delivery formats for gerontology courses in dental hygiene curricula. This study examines the effectiveness of alternative methods of course delivery by comparing student profiles and instructional outcomes from a dental hygiene gerontology course offered both on the Web and in a traditional classroom setting. Questionnaires were sent to both groups of students completing the course. The instrument was designed to establish profiles of the participating students. The data collected included familiarity with Web-based instruction, extent of prior computer training, previous interaction with the elderly, and student evaluations of course effectiveness. Traditional instructional outcomes from evaluated course work were compared, as were post-course exam outcomes that assessed retention of course information six months after course completion. The statistical significance of these data was determined using Statistical Package for Social Scientists software (SPSS, Inc., version 12.0, Chicago, IL). A comparison of student characteristics enrolled in the two course formats revealed marked differences. The Web-based group (n=12) included dental hygiene students (67%) and other health care providers (25%). All participants in the traditional classroom format (n=32) were dental hygiene students. Half of the Web-based respondents were over 25 years of age, and the majority (n=8) had previously taken an online course. The majority of traditional classroom students were 25 years of age or younger (n=21) and had never taken a Web-based course (n=20). Statistically significant differences in instructional outcomes were observed between students enrolled in these two formats. Student retention of course material six months after completion of the course was greater in the Web-based format. Students selecting a Web-based course format demonstrated greater motivation and learning success based on final course grades, completion of assignments, and knowledge retention over time. Age, previous experience with online courses, and selection of teaching mode are factors that may confound course delivery method to influence instructional outcomes in a gerontology course within a dental hygiene curriculum.

The present study examined the comparative effects of a prediction/discussion-based learning cycle, conceptual change text (CCT), and traditional instructions on students' understanding of genetics concepts. A quasi-experimental research design of the pre-test-post-test non-equivalent control group was adopted. The three intact classes, taught by the same science teacher, were randomly assigned as prediction/discussion-based learning cycle class (N = 30), CCT class (N = 25), and traditional class (N = 26). Participants completed the genetics concept test as pre-test, post-test, and delayed post-test to examine the effects of instructional strategies on their genetics understanding and retention. While the dependent variable of this study was students' understanding of genetics, the independent variables were time (Time 1, Time 2, and Time 3) and mode of instruction. The mixed between-within subjects analysis of variance revealed that students in both prediction/discussion-based learning cycle and CCT groups understood the genetics concepts and retained their knowledge significantly better than students in the traditional instruction group.

Background: Advances in minimally invasive surgery have led to the emergence of single-incision laparoscopic surgery (SILS). The purpose of this study is to assess the feasibility of SILS Nissen fundoplication and compare its outcomes with traditional laparoscopic Nissen fundoplication. Methods: This is a retrospective study of 33 patients who underwent Nissen fundoplication between January 2009 and September 2010. Results: There were 15 SILS and 18 traditional laparoscopic Nissen fundoplication procedures performed. The mean operative time was 129 and 182 minutes in the traditional laparoscopic and single-incision groups, respectively (P = .019). There were no conversions in the traditional laparoscopic group, whereas 6 of the 15 patients in the SILS group required conversion by insertion of 2 to 4 additional ports (P = .0004). At short-term follow-up, recurrence rates were similar between both groups. To date, there have been no reoperations. Conclusions: SILS Nissen fundoplication is both safe and feasible. Short-term outcomes are comparable with standard laparoscopic Nissen fundoplication. Challenges related to the single-incision Nissen fundoplication include overcoming the lengthy learning curve and decreasing the need for additional trocars. PMID:25392613

Bejanyan, Kathrine; Marshall, Tara C.; Ferenczi, Nelli

2014-01-01

Previous studies have established that Indians tend to be greater in collectivism and gender role traditionalism than Americans. The purpose of the present study was to examine whether these differences explained further cultural differences in romantic beliefs, traditional mate preferences, and anticipation of future difficulties in marital life. Results revealed that Indians reported greater collectivism than Americans and, in turn, held stronger romantic beliefs. Additionally, Indians' greater collectivism and endorsement of more traditional gender roles in part predicted their preferences for a marital partner possessing traditional characteristics, and fully accounted for their heightened concerns about encountering future difficulties in marital life. These results shed light on the processes underlying cultural differences in relationship attitudes and preferences, and point to culture-specific therapies to enhance marital functioning.

To examine the influence of traditional tobacco use on smoking cessation among American Indian adult smokers. A cross-sectional survey of self-identified American Indians was conducted from 2008 to 2009. A total of 998 American Indian adults (18 years and older) from the Midwest participated in the study. Traditional tobacco use and method of traditional use were both assessed. Commercial tobacco use (current smoking) was obtained through self-reported information as well as the length of their most recent quit attempt. We also assessed knowledge and awareness of pharmacotherapy for current smokers. Among participants in our study, 33.3% were current smokers and they reported smoking an average of 10 cigarettes per day. American Indian current smokers who used traditional tobacco reported a greater number of days abstinent during their last quit attempt compared to those who do not use traditional tobacco (P = 0.01). However, it appears that this protective effect of traditional tobacco use is diminished if the person smokes traditional tobacco. Finally, very few (fewer than 20% of current smokers) were aware of more recent forms of pharmacotherapy such as Chantix or bupropion. American Indians appear to show low levels of awareness of effective pharmacotherapies to aid smoking cessation, but those who use 'traditional tobacco' report somewhat longer periods of abstinence from past quit attempts. © 2011 The Authors, Addiction © 2011 Society for the Study of Addiction.

Evaluation of Team-Based Learning and Traditional Instruction in Teaching Removable Partial Denture Concepts.

PubMed

Echeto, Luisa F; Sposetti, Venita; Childs, Gail; Aguilar, Maria L; Behar-Horenstein, Linda S; Rueda, Luis; Nimmo, Arthur

2015-09-01

The aim of this study was to evaluate the effectiveness of team-based learning (TBL) methodology on dental students' retention of knowledge regarding removable partial denture (RPD) treatment. The process of learning RPD treatment requires that students first acquire foundational knowledge and then use critical thinking skills to apply that knowledge to a variety of clinical situations. The traditional approach to teaching, characterized by a reliance on lectures, is not the most effective method for learning clinical applications. To address the limitations of that approach, the teaching methodology of the RPD preclinical course at the University of Florida was changed to TBL, which has been shown to motivate student learning and improve clinical performance. A written examination was constructed to compare the impact of TBL with that of traditional teaching regarding students' retention of knowledge and their ability to evaluate, diagnose, and treatment plan a partially edentulous patient with an RPD prosthesis. Students taught using traditional and TBL methods took the same examination. The response rate (those who completed the examination) for the class of 2013 (traditional method) was 94% (79 students of 84); for the class of 2014 (TBL method), it was 95% (78 students of 82). The results showed that students who learned RPD with TBL scored higher on the examination than those who learned RPD with traditional methods. Compared to the students taught with the traditional method, the TBL students' proportion of passing grades was statistically significantly higher (p=0.002), and 23.7% more TBL students passed the examination. The mean score for the TBL class (0.758) compared to the conventional class (0.700) was statistically significant with a large effect size, also demonstrating the practical significance of the findings. The results of the study suggest that TBL methodology is a promising approach to teaching RPD with successful outcomes.

Clinical education is vital to both the development of clinical self-efficacy and the integration of future nurses into health care teams. The dedicated education unit clinical teaching model is an innovative clinical partnership, which promotes skill development, professional growth, clinical self-efficacy, and integration as a team member. Blended clinical teaching models are combining features of the dedicated education unit and traditional clinical model. The aims of this study are to explore how each of three clinical teaching models (dedicated education unit, blended, traditional) affects clinical self-efficacy and attitude toward team process, and to compare the dedicated education unit model and blended model to traditional clinical. A nonequivalent control-group quasi-experimental design was utilized. The convenience sample of 272 entry-level baccalaureate nursing students included 84 students participating in a dedicated education unit model treatment group, 66 students participating in a blended model treatment group, and 122 students participating in a traditional model control group. Perceived clinical self-efficacy was evaluated by the pretest/posttest scores obtained on the General Self-Efficacy scale. Attitude toward team process was evaluated by the pretest/posttest scores obtained on the TeamSTEPPS® Teamwork Attitude Questionnaire. All three clinical teaching models resulted in significant increases in both clinical self-efficacy (p=0.04) and attitude toward team process (p=0.003). Students participating in the dedicated education unit model (p=0.016) and students participating in the blended model (p<0.001) had significantly larger increases in clinical self-efficacy compared to students participating in the traditional model. These findings support the use of dedicated education unit and blended clinical partnerships as effective alternatives to the traditional model to promote both clinical self-efficacy and team process among entry-level baccalaureate nursing students.

2016-01-01

Growing attention in the past few decades has focused on improving care quality and quality of life for nursing home residents. Many traditional nursing homes have attempted to transform themselves to become more homelike emphasizing individualized care. This trend is referred to as nursing home culture change in the U.S. A promising culture change nursing home model, the Green House nursing home model, has shown positive psychological outcomes. However, little is known about whether the Green House nursing home model has positive effects on physical function compared to traditional nursing homes. To examine the longitudinal effects of the Green House nursing home model by comparing change patterns of activities of daily living function over time between Green House home residents and traditional nursing home residents. A retrospective longitudinal study. Four Green House organizations (nine Green House units and four traditional units). A total of 242 residents (93 Green House residents and 149 traditional home residents) who had stayed in the nursing home at least 6 months from admission. The outcome was activities of daily living function, and the main independent variable was the facility type in which the resident stayed: a Green House or traditional unit. Age, gender, comorbidity score, cognitive function, and depressive symptoms at baseline were controlled. All of these measures were from a minimum dataset. Growth curve modeling and growth mixture modeling were employed in this study for longitudinal analyses. The mean activities of daily living function showed deterioration over time, and the rates of deterioration between Green House and traditional home residents were not different over time. Four different activities of daily living function trajectories were identified for 18 months, but there was no statistical difference in the likelihood of being in one of the four trajectory classes between the two groups. Although Green House nursing homes are considered to represent an innovative model changing the nursing home environment into more person-centered, this study did not demonstrate significant differences in activities of daily living function changes for residents in the Green House nursing homes compared to traditional nursing homes. Given that the Green House model continues to evolve as it is being implemented and variations within and across Green House homes are identified, large-scale longitudinal studies are needed to provide further relevant information on the effects of the Green House model.

2016-08-01

This is the first study to measure the 'sense of community' reportedly offered by the CrossFit gym model. A cross-sectional study adapted Social Capital and General Belongingness scales to compare perceptions of a CrossFit gym and a traditional gym. CrossFit gym members reported significantly higher levels of social capital (both bridging and bonding) and community belongingness compared with traditional gym members. However, regression analysis showed neither social capital, community belongingness, nor gym type was an independent predictor of gym attendance. Exercise and health professionals may benefit from evaluating further the 'sense of community' offered by gym-based exercise programmes.

A method to determine agro-climatic zones based on correlation and cluster analyses

NASA Astrophysics Data System (ADS)

Borges Valeriano, Taynara Tuany; de Souza Rolim, Glauco; de Oliveira Aparecido, Lucas Eduardo

2017-12-01

Determining agro-climatic zones (ACZs) is traditionally made by cross-comparing meteorological elements such as air temperature, rainfall, and water deficit (DEF). This study proposes a new method based on correlations between monthly DEFs during the crop cycle and annual yield and performs a multivariate cluster analysis on these correlations. This `correlation method' was applied to all municipalities in the state of São Paulo to determine ACZs for coffee plantations. A traditional ACZ method for coffee, which is based on temperature and DEF ranges (Evangelista et al.; RBEAA, 6:445-452, 2002), was applied to the study area to compare against the correlation method. The traditional ACZ classified the "Alta Mogina," "Média Mogiana," and "Garça and Marília" regions as traditional coffee regions that were either suitable or even restricted for coffee plantations. These traditional regions have produced coffee since 1800 and should not be classified as restricted. The correlation method classified those areas as high-producing regions and expanded them into other areas. The proposed method is innovative, because it is more detailed than common ACZ methods. Each developmental crop phase was analyzed based on correlations between the monthly DEF and yield, improving the importance of crop physiology in relation to climate.

In this study, I compared the physical elements of two Indonesian traditional houses between a Kaili tribe (Central Sulawesi) and a Bugis-Makassar tribe (South Sulawesi). If we viewed of the name, meaning and function from both traditional houses have similarities, namely the Souraja/Saoraja house (House of the King), however, observed more detail the physical elements of architecture also show the differences. The spatial, physical and stylistic systems (N. John Habraken’s theory) were applied to analyze their differences and the similarities of the physical elements of architecture on those two traditional houses. The results of the analysis identified that the physical elements of architecture such as the orientation, the function and distribution of rooms (the spatial system), the constructions and materials of floor, wall and roof (the physical system) and the opening types of the door and window as well as ornaments used showed similarities. Meanwhile the physical elements of architecture such as the arrangement of columns, form and spatial pattern as well as the placement of the stairs (the spatial system), the constructions and materials of foundation, column and beam (the physical system) as well as the form of the roof and façade found differences of both traditional houses.

This study involves revealing the spatial organization typology differences between pre and post disaster houses through core house project in Kasongan, Yogyakarta, Indonesia. The goal is to gain understanding of the way of traditional cultured people re-shaping their space and environment after disaster reconstruction through the core house and find the factors that determine the form. The study has been done by comparing and analyzing the spatial properties and functions between both objects using justified graph technique which is one of the basic methodology that able to identify how people are organized in space. Upon the comparison and analysis of these aspects, it appears that the old house size has impact toward significant changes of the spatial properties also the dwellers put physical factor over culture when evaluating the present house. Through these findings, this study highlights that spatial organization of traditional house has temporal spatial value and the core house concept had influenced the changes of the local spatial behaviour and their perception of their house standard.

A meta-analysis on the effectiveness of computer-assisted instruction in science education

Bayraktar, Sule

2000-10-01

The purposes of this study were to determine whether Computer-Assisted Instruction (CAI) had an overall positive effect on student achievement in secondary and college level science education when compared with traditional forms of instruction and to determine whether specific study or program characteristics were related to CAI effectiveness. This study employed a meta analytic research approach. First, the research studies comparing student achievement between CAI and traditional instruction in science were located by using electronic search databases. The search resulted in 42 studies producing 108 effect sizes. Second, the study features and effect sizes for each study were coded. Finally, the effect sizes provided from each study were combined to provide an overall effect size, and relationships between effect sizes and study features were then examined. The overall effect size was found to be 0.273 standard deviations, suggesting that CAI has a small positive effect on student achievement in science education at the college and secondary levels when compared with traditional forms of instruction. An effect size of 0.273 standard deviations indicates that an average student exposed to CAI exceeded the performance of 62% of the students who were taught by using traditional instructional methods. In other words, the typical student moved from the 50th percentile to the 62 nd percentile in science when CAI was used. All variables excluding school level and publication status were found to be related to effect sizes. According to the results of the analysis, CAI was most effective in physics education and had little effect on chemistry and biology achievement. Simulation and tutorial programs had significant effects on student achievement in science education but drill and practice was not found effective. The results also indicated that individual utilization of CAI was preferable. Another finding from the study is that experimenter-developed software was more effective than commercial, and that CAI was more effective than traditional instruction when the duration of treatment was shorter than 4 weeks. Furthermore, the results also indicated that the effectiveness of CAI in science subject areas decreased over the decades.

Student perceptions of digital versus traditional slide use in undergraduate education.

Solberg, Brooke L

2012-01-01

Digitized slides provide a number of intriguing benefits for educators. Before their implementation, however, educators should consider student opinion related to their use. This mixed-methods study directly compared Medical Laboratory Science (MLS) student perceptions of learning experiences in both digital and traditional slide laboratory settings. Results suggested that the majority of students preferred learning with digital slides, and numerous reasons for this preference were identified. Survey responses indicated that students using digital slides tended to view their performances, instructor feedback, and their learning environment more positively than students using traditional slides. Apprehensions about digital slide use were also detected from students preferring traditional slides. These findings provide a guide on how best to exploit both digital and traditional slides in an educational setting.

2015-12-01

The work presented in this paper compares traditional Chinese medicine and traditional Thai medicine, expounding on origins, academic thinking, theoretical system, diagnostic method and modern development. Based on a secondary analysis of available literature, the paper concentrates on two crucial historical developments: (1) the response to, and consequences of, the impact of the Western medicine; and (2) the revival of traditional medicine in these two countries and its prospects. From a comparative perspective, the analysis has led to the conclusion that the rise and fall of traditional medicine is an issue closely related with social and political issues; and the development of traditional medicines requires national policy and financial support from governments, human resource development, the improvement of service quality, and the dissemination of traditional medicine knowledge to the public. In addition, this paper also suggests deepening exchanges and cooperation between China and Thailand, strengthening cooperation between traditional medicine and medical tourism.

2001-11-01

To delineate with computed tomography (CT) the anatomic regions containing the supraclavicular (SCV) and infraclavicular (IFV) nodal groups, to define the course of the brachial plexus, to estimate the actual radiation dose received by these regions in a series of patients treated in the traditional manner, and to compare these doses to those received with an optimized dosimetric technique. Twenty patients underwent contrast material-enhanced CT for the purpose of radiation therapy planning. CT scans were used to study the location of the SCV and IFV nodal regions by using outlining of readily identifiable anatomic structures that define the nodal groups. The brachial plexus was also outlined by using similar methods. Radiation therapy doses to the SCV and IFV were then estimated by using traditional dose calculations and optimized planning. A repeated measures analysis of covariance was used to compare the SCV and IFV depths and to compare the doses achieved with the traditional and optimized methods. Coverage by the 90% isodose surface was significantly decreased with traditional planning versus conformal planning as the depth to the SCV nodes increased (P < .001). Significantly decreased coverage by using the 90% isodose surface was demonstrated for traditional planning versus conformal planning with increasing IFV depth (P = .015). A linear correlation was found between brachial plexus depth and SCV depth up to 7 cm. Conformal optimized planning provided improved dosimetric coverage compared with standard techniques.

Aurorae in Australian Aboriginal Traditions

Hamacher, Duane W.

2013-07-01

Transient celestial phenomena feature prominently in the astronomical knowledge and traditions of Aboriginal Australians. In this paper, I collect accounts of the Aurora Australis from the literature regarding Aboriginal culture. Using previous studies of meteors, eclipses, and comets in Aboriginal traditions, I anticipate that the physical properties of aurora, such as their generally red colour as seen from southern Australia, will be associated with fire, death, blood, and evil spirits. The survey reveals this to be the case and also explores historical auroral events in Aboriginal cultures, aurorae in rock art, and briefly compares Aboriginal auroral traditions with other global indigenous groups, including the Maori of New Zealand.

Traditional medicine is widely used in East Asia, and studies that demonstrate its usefulness have recently become more common. However, formulation-based studies are not globally understood because these studies are country-specific. There are many types of formulations that have been introduced to Japan and Korea from China. Establishing whether a same-origin formulation has equivalent effects in other countries is important for the development of studies that span multiple countries. The present study compared the effects of same-origin traditional medicine used in Japan and Korea in an in vivo experiment. We prepared drugs that had the same origin and the same components. The drugs are called kamikihito (KKT) in Japan and kami-guibi-tang (KGT) in Korea. KKT (500 mg extract/kg/day) and KGT (500 mg extract/kg/day) were administered to ddY mice, and object recognition and location memory tests were performed. KKT and KGT administration yielded equivalent normal memory enhancement effects. 3D-HPLC showed similar, but not identical, patterns of the detected compounds between KKT and KGT. This comparative research approach enables future global clinical studies of traditional medicine to be conducted through the use of the formulations prescribed in each country.

Background The aim of this study was to investigate the feasibility of the application of high-intensity focused ultrasound (HIFU) hat-type ablation mode in in vitro and in vivo models, and to compare the ablation effects of different parameter combinations. Material/Methods HIFU hat-type ablation was performed in isolated bovine liver tissue and in the liver tissue in living rabbits, and the coagulative necrosis for different parameter combinations (plane angles and irradiation order) was investigated. We also analyzed and compared the ablation effects of traditional ablation and hat-type ablation modes. Coagulative necrosis morphology was detected with TTC staining, and the coagulative necrosis volume and energy efficiency factor (EEF) were calculated and compared. Results Coagulative necrosis was observed in all the ablated groups, and the coagulative necrosis volume was much larger than the irradiation area. The coagulative necrosis induced by the hat-type ablation was more regular and controllable than the traditional ablation. The angles between the ablation planes determined the coagulative necrosis morphology, but did not affect the coagulative necrosis volume. Moreover, the irradiation order significantly influenced the coagulative necrosis. Importantly, under certain conditions, hat-type ablation achieved higher efficiency compared with the traditional ablation mode. Conclusions Compared with the traditional ablation mode, HIFU hat-type ablation effectively shortened the irradiation time, reduced the over-accumulation of energy, and increased the HIFU ablation efficiency.

To compare the hydro-surgical technique to traditional techniques for removal of subcutaneous tissue in the preparation of full-thickness skin grafts. Ex vivo experimental study and a single clinical case report. Four canine cadavers and a single clinical case. Four sections of skin were harvested from the lateral flank of recently euthanatized dogs. Traditional preparation methods used included both a blade or scissors technique, each of which were compared to the hydro-surgical technique individually. Preparation methods were compared based on length of time for removal of the subcutaneous tissue from the graft, histologic grading, and measurable thickness as compared to an untreated sample. The hydro-surgical technique had the shortest skin graft preparation time as compared to traditional techniques (p = 0.002). There was no significant difference in the histological grading or measurable subcutaneous thickness between skin specimens. The hydro-surgical technique provides a rapid, effective debridement of subcutaneous tissue in the preparation of full-thickness skin grafts. There were not any significant changes in histological grade and subcutaneous tissue remaining among all treatment types. Additionally the hydro-surgical technique was successfully used to prepare a full-thickness meshed free skin graft in the reconstruction of a traumatic medial tarsal wound in a dog.

Traditional and complementary medicine (T&CM) plays an integral role in providing health care worldwide. It is based on sound fundamental principles and centuries of practices. This study compared traditional Indian medicine (TIM) and traditional Korean medicine (TKM) basing on data obtained from peer reviewed articles, respective government institutional reports and World Health Organization reports. Despite the fact that TIM and TKM have individual qualities that are unique from each other including different histories of origin, they share a lot in common. Apart from Homeopathy in TIM, both systems are hinged on similar principle of body constitutional-based concept and similar disease diagnosis methods of mainly auscultation, palpation, visual inspection, and interrogation. Similarly, the treatment methods of TIM and TKM follow similar patterns involving use of medicinal herbs, moxibustion, acupuncture, cupping, and manual therapy. Both T&CM are majorly practiced in well-established hospitals by T&CM doctors who have undergone an average of 6-7 years of specialized trainings. However, unlike TIM which has less insurance coverage, the popularity of TKM is majorly due to its wide national insurance coverage. These two medical traditions occupy increasingly greater portion of the global market. However, TIM especially Ayurveda has gained more global recognition than TKM although the emergence of Sasang Constitutional Medicine in TKM is beginning to become more popular. This comparative analysis between TIM and TKM may provide vital and insightful contribution towards constitutional-based concept for further development and future studies in T&CM.

Traditional Advanced Cardiac Life Support (ACLS) courses are evaluated using written multiple-choice tests. High-fidelity simulation is a widely used adjunct to didactic content, and has been used in many specialties as a training resource as well as an evaluative tool. There are no data to our knowledge that compare simulation examination scores with written test scores for ACLS courses. To compare and correlate a novel high-fidelity simulation-based evaluation with traditional written testing for senior medical students in an ACLS course. We performed a prospective cohort study to determine the correlation between simulation-based evaluation and traditional written testing in a medical school simulation center. Students were tested on a standard acute coronary syndrome/ventricular fibrillation cardiac arrest scenario. Our primary outcome measure was correlation of exam results for 19 volunteer fourth-year medical students after a 32-hour ACLS-based Resuscitation Boot Camp course. Our secondary outcome was comparison of simulation-based vs. written outcome scores. The composite average score on the written evaluation was substantially higher (93.6%) than the simulation performance score (81.3%, absolute difference 12.3%, 95% CI [10.6-14.0%], p<0.00005). We found a statistically significant moderate correlation between simulation scenario test performance and traditional written testing (Pearson r=0.48, p=0.04), validating the new evaluation method. Simulation-based ACLS evaluation methods correlate with traditional written testing and demonstrate resuscitation knowledge and skills. Simulation may be a more discriminating and challenging testing method, as students scored higher on written evaluation methods compared to simulation.

To examine the influence of meal decision-making and preparation on Hispanic women's dietary practices. One-on-one structured interviews were conducted, assessing meal decision-making and preparation practices, barriers, and behavioral strategies to eating low-fat and high-fiber diets, fat and fiber intake, demographic, and other psychosocial factors. The study population included 357 Hispanic women living in the southern or central regions of San Diego County. Participants were recruited via random-digit dialing to a tailored nutrition communication intervention. Household decision-making style (alone vs with family) by household activity (decides meals, prepares meals, and decides snacks). Multiple logistic regressions were used to evaluate associations between the predictors and dependent variable. All models included adjustments for potential confounders, such as marital status, education, employment, age, and acculturation. A positive statistical association between Hispanic women's acculturation level and shared decision-making style was found. Also, Hispanic women in shared decision-making households faced greater psychosocial barriers to healthful eating and reported less healthful eating compared with Hispanic women in traditional households. Women in shared decision-making households were more likely to eat at fast-food restaurants, less likely to engage in behavioral strategies promoting fiber consumption, eat more saturated fat, and encounter more barriers to reduce dietary fat as compared with Hispanic women in traditional households. Acculturation did not attenuate differences in psychosocial and dietary practices between shared decision-making and traditional households. Study findings suggest intervention efforts should focus on different aspects of healthful eating among Hispanic women in shared-decision, compared with traditional, households.

Accurate recording of the nursing care indicates the care performance and its quality, so that, any failure in documentation can be a reason for inadequate patient care. Therefore, improving nurses' skills in this field using effective educational methods is of high importance. Since traditional teaching methods are not suitable for communities with rapid knowledge expansion and constant changes, e-learning methods can be a viable alternative. To show the importance of e-learning methods on nurses' care reporting skills, this study was performed to compare the e-learning methods with the traditional instructor-led methods. This was a quasi-experimental study aimed to compare the effect of two teaching methods (e-learning and lecture) on nursing documentation and examine the differences in acquiring competency on documentation between nurses who participated in the e-learning (n = 30) and nurses in a lecture group (n = 31). The results of the present study indicated that statistically there was no significant difference between the two groups. The findings also revealed that statistically there was no significant correlation between the two groups toward demographic variables. However, we believe that due to benefits of e-learning against traditional instructor-led method, and according to their equal effect on nurses' documentation competency, it can be a qualified substitute for traditional instructor-led method. E-learning as a student-centered method as well as lecture method equally promote competency of the nurses on documentation. Therefore, e-learning can be used to facilitate the implementation of nursing educational programs.

High-quality cardiopulmonary resuscitation contributes to cardiac arrest survival. The traditional chest compression (CC) standard, which neglects individual differences, uses unified standards for compression depth and compression rate in practice. In this study, an effective and personalized CC method for automatic mechanical compression devices is provided. We rebuild Charles F. Babbs' human circulation model with a coronary perfusion pressure (CPP) simulation module and propose a closed-loop controller based on a fuzzy control algorithm for CCs, which adjusts the CC depth according to the CPP. Compared with a traditional proportion-integration-differentiation (PID) controller, the performance of the fuzzy controller is evaluated in computer simulation studies. The simulation results demonstrate that the fuzzy closed-loop controller results in shorter regulation time, fewer oscillations and smaller overshoot than traditional PID controllers and outperforms the traditional PID controller for CPP regulation and maintenance.

Shoulder pain is common in society, with high prevalence in the general population. Shoulder impingement syndrome (SIS) is the most frequent cause. Patients suffer pain, muscle weakness and loss of movement in the affected joint. Initial treatment is predominantly conservative. The surgical option has high success rates and is often used when conservative strategy fails. Traditional physiotherapy and post-operative exercises are needed for the recovery of joint range, muscle strength, stability and functionality. Telerehabilitation programmes have shown positive results in some orthopaedic conditions after surgery. Customized telerehabilitation intervention programmes should be developed to recover shoulder function after SIS surgery. The objective of this study is to evaluate the feasibility and effectiveness of a telerehabilitation intervention compared with usual care in patients after subacromial decompression surgery. We will compare an intervention group receiving videoconferences and a telerehabilitation programme to a control group receiving traditional physiotherapy intervention in a single-blind, randomized controlled non-inferiority trial study design. Through this study, we will further develop our preliminary data set and practical experience with the telerehabilitation programmes to evaluate their effectiveness and compare this with traditional intervention. We will also explore patient satisfaction and cost-effectiveness. Patient enrolment is ongoing. ClinicalTrials.gov, NCT02909920 . 14 September 2016.

Geologic mapping involves interpreting relationships between identifiable units and landforms to understand the formative history of a region. Traditional field techniques are used to accomplish this on Earth. Mapping proves more challenging for other planets, which are studied primarily by orbital remote sensing and, less frequently, by robotic and human surface exploration. Systematic comparative assessments of geologic maps created by traditional mapping versus photogeology together with data from planned traverses are limited. The objective of this project is to produce a geologic map from data collected on the Desert Research and Technology Studies (RATS) 2010 analog mission using Apollo-style traverses in conjunction with remote sensing data. This map is compared with a geologic map produced using standard field techniques.

The objective of this study was to determine the feasibility of developing and using a voice recognition computerized charting system to record dental clinical examination data. More specifically, the study was designed to analyze the time and error differential between the traditional examiner/recorder method (ASSISTANT) and computerized voice recognition method (VOICE). DMFS examinations were performed twice on 20 patients using the traditional ASSISTANT and the VOICE charting system. A statistically significant difference was found when comparing the mean ASSISTANT time of 2.69 min to the VOICE time of 3.72 min (P less than 0.001). No statistically significant difference was found when comparing the mean ASSISTANT recording errors of 0.1 to VOICE recording errors of 0.6 (P = 0.059). 90% of the patients indicated they felt comfortable with the dentist talking to a computer and only 5% of the sample indicated they opposed VOICE. Results from this pilot study indicate that a charting system utilizing voice recognition technology could be considered a viable alternative to traditional examiner/recorder methods of clinical charting.

Goniometers are commonly used by physical therapists to measure range-of-motion (ROM) in the musculoskeletal system. These measurements are used to assist in diagnosis and to help monitor treatment efficacy. With newly emerging technologies, smartphone-based applications are being explored for measuring joint angles and movement. This pilot study investigates the intra- and inter-rater reliability as well as concurrent validity of a newly-developed smartphone magnetometer-based goniometer (MG) application for measuring passive shoulder abduction in both sitting and supine positions, and compare against the traditional universal goniometer (UG). This is a comparative study with repeated measurement design. Three physical therapists utilized both the smartphone MG and a traditional UG to measure various angles of passive shoulder abduction in a healthy subject, whose shoulder was positioned in eight different positions with pre-determined degree of abduction while seated or supine. Each therapist was blinded to the measured angles. Concordance correlation coefficients (CCCs), Bland-Altman plotting methods, and Analysis of Variance (ANOVA) were used for statistical analyses. Both traditional UG and smartphone MG were reliable in repeated measures of standardized joint angle positions (average CCC > 0.997) with similar variability in both measurement tools (standard deviation (SD) ± 4°). Agreement between the UG and MG measurements was greater than 0.99 in all positions. Our results show that the smartphone MG has equivalent reliability compared to the traditional UG when measuring passive shoulder abduction ROM. With concordant measures and comparable reliability to the UG, the newly developed MG application shows potential as a useful tool to assess joint angles. Published by Elsevier Ltd.

Individual placement and support (IPS) is a vocational rehabilitation programme that was developed in the USA to improve employment outcomes for people with severe mental illness. Its ability to be generalised to other countries and its effectiveness in varying economic conditions remains to be ascertained. To investigate whether IPS is effective across international settings and in different economic conditions. A systematic review and meta-analysis of randomised controlled trials comparing IPS with traditional vocational services was undertaken; 17 studies, as well as 2 follow-up studies, were included. Meta-regressions were carried out to examine whether IPS effectiveness varied according to geographic location, unemployment rates or gross domestic product (GDP) growth. The overall pooled risk ratio for competitive employment using IPS compared with traditional vocational rehabilitation was 2.40 (95% CI 1.99-2.90). Meta-regressions indicated that neither geographic area nor unemployment rates affected the overall effectiveness of IPS. Even when a country's GDP growth was less than 2% IPS was significantly more effective than traditional vocational training, and its benefits remained evident over 2 years. Individual placement and support is an effective intervention across a variety of settings and economic conditions and is more than twice as likely to lead to competitive employment when compared with traditional vocational rehabilitation. © The Royal College of Psychiatrists 2016.

2017-09-22

Digital technologies in health care are expected to increase in scope and to affect ever more parts of the health care system. It is important to enhance the knowledge of whether new digital methods and innovations provide value for money compared with traditional models of care. The objective of the study was to evaluate whether a digital health care model for primary care is a less costly alternative compared with traditional in-office primary care in Sweden. Cost data for the two care models were collected and analyzed to obtain a measure in local currency per care contact. The comparison showed that the total economic cost of a digital consultation is 1960 Swedish krona (SEK) (SEK100 = US$11.29; February 2017) compared with SEK3348 for a traditional consultation at a health care clinic. Cost differences arose on both the provider side and on the user side. The digital health care model may be a less costly alternative to the traditional health care model. Depending on the rate of digital substitution, gross economic cost savings of between SEK1 billion and SEK10 billion per year could be realized if more digital consultations were made. Further studies are needed to validate the findings, assess the types of care most suitable for digital care, and also to obtain various quality-adjusted outcome measures.

The uses of anti-diabetic plants are well anchored in the traditional health care system of Pakistan. To the best of our knowledge, this is the first ethno-botanical study about the uses of plants for the treatment of diabetes. The aim of the study is to record indigenous knowledge on anti-diabetic plants from Traditional Health Practitioners (THPs) and diabetic patients. In addition, it is aimed to ascertain and validate the traditional uses of anti-diabetic plants by citing pharmacological activities and phytochemical constitutes from previously published literature. The ethno-medicinal data was documented during 14 field surveys, each comprising of 10 days, from 3 regions of Pakistan (Islamabad, Khyber Pukhtoonkhwa and Deserts of Sindh). In total, 113 THPs and 44 diabetic patients were interviewed using open-ended and semi-structured questionnaires. Quantitative indices, including Relative Frequency of Citation percentage (RFC %) and Disease Consensus Index (DCI) were calculated. The documented data is authenticated by comparing with 28 published articles on ethno-botanical aspects and many pharmacological studies. In total, 120 plant species belonging to 50 families were reported. The ethno-botanical results indicated that Moraceae (11 species); herb (56 reports) is dominant life form; the leaves (56 reports) are the most used plant part and decoction (24%) is the preferred mode of preparation. The quantitative analysis shows that RFC% ranges from 14 to 42 and DCI varies from 0.15 to 0.74. By comparing to previous studies, 64 species are reported new in traditional treatment of DM; 40 species are new to pharmacological evidence and 3 species are new to phytochemical studies. This study recoded the significant indigenous knowledge about anti-diabetic plants among the THPs and diabetic patients in Pakistan. This type of ethno-botanical knowledge on traditional use of anti-diabetic plants is an important step in designing detailed pharmacological and clinical trials for Diabetes Miletus treatment. It is recommended that further pharmacological and phytochemical analysis should be conducted on those species which lack previous references in literature and have highest Frequency of Citation (FC), Disease Consensus Index (DCI) and Relative Frequency of Citation percentage (RFC%).

The aim of this study was to compare the effects of 6-week cluster versus traditional plyometric training sets on jumping ability, sprint and agility performance. Thirteen college students were assigned to a cluster sets group (N=6) or traditional sets group (N=7). Both training groups completed the same training program. The traditional group completed five sets of 20 repetitions with 2min of rest between sets each session, while the cluster group completed five sets of 20 [2×10] repetitions with 30/90-s rest each session. Subjects were evaluated for countermovement jump (CMJ), standing long jump (SLJ), t test, 20-m and 40-m sprint test performance before and after the intervention. Both groups had similar improvements (P<0.05) in CMJ, SLJ, t test, 20-m, and 40-m sprint. However, the magnitude of improvement in CMJ, SLJ and t test was greater for the cluster group (effect size [ES]=1.24, 0.81 and 1.38, respectively) compared to the traditional group (ES=0.84, 0.60 and 0.55). Conversely, the magnitude of improvement in 20-m and 40-m sprint test was greater for the traditional group (ES=1.59 and 0.96, respectively) compared to the cluster group (ES=0.94 and 0.75, respectively). Although both plyometric training methods improved lower body maximal-intensity exercise performance, the traditional sets methods resulted in greater adaptations in sprint performance, while the cluster sets method resulted in greater jump and agility adaptations.

The purpose of this study was to evaluate the impact of group prenatal care on rates of preterm birth. We conducted a retrospective cohort study of 316 women in group prenatal care that was compared with 3767 women in traditional prenatal care. Women self-selected participation in group care. Risk factors for preterm birth were similar for group prenatal care vs traditional prenatal care: smoking (16.9% vs 20%; P = .17), sexually transmitted diseases (15.8% vs 13.7%; P = .29), and previous preterm birth (3.2% vs 5.4%; P = .08). Preterm delivery (<37 weeks' gestation) was lower in group care than traditional care (7.9% vs 12.7%; P = .01), as was delivery at <32 weeks' gestation (1.3% vs 3.1%; P = .03). Adjusted odds ratio for preterm birth for participants in group care was 0.53 (95% confidence interval, 0.34-0.81). The racial disparity in preterm birth for black women, relative to white and Hispanic women, was diminished for the women in group care. Among low-risk women, participation in group care improves the rate of preterm birth compared with traditional care, especially among black women. Randomized studies are needed to eliminate selection bias. Copyright © 2012 Mosby, Inc. All rights reserved.

It has been proposed that a new sling exercise therapy may promote neuromuscular control of the neck. To compare the effects of traditional physiotherapy vs traditional physiotherapy combined with a new sling exercise therapy on discomfort and function in patients with chronic whiplash-associated disorders who have unsettled compensation claims; and to investigate possible additional effects of guided, long-term home training. A randomized multi-centre trial with 4 parallel groups. A total of 214 patients were assigned randomly to 4 treatment groups, and received either traditional physiotherapy with or without home training, or new sling exercise therapy with or without home training. Outcome measures were pain, disability, psychological distress, sick leave and physical tests. A total of 171 patients (80%) completed the study. There were no important statistical or clinical differences between the groups after 4 months of treatment. There was a small statistically significant effect at 12-month follow-up in both groups with home training regarding pain during rest (p = 0.05) and reported fatigue in the final week (p = 0.02). No statistically significant differences were found between the traditional physiotherapy group and the new sling exercise group, with or without home training. Since the groups were not compared with a control group without treatment, we cannot conclude that the studied treatments are effective for patients with whiplash-associated disorder, only that they did not differ in our study.

Arcury, Thomas A; Sandberg, Joanne C; Mora, Dana C; Talton, Jennifer W; Quandt, Sara A

2016-01-01

Farmworkers in the United States experience high rates of injury and illness but have limited access to conventional health care. Farmworkers are often from countries that have active traditional healers, so understanding the use of traditional healers among farmworkers is important. This pilot study (1) describes the use of traditional healers among farmworkers and (2) compares the use of traditional healers by farmworkers with other Latino immigrants. Interviews were conducted in 2015 with 100 Mexican farmworkers (80 men, 20 women) and 100 Mexican immigrant non-farmworkers (50 men, 50 women) in North Carolina. Most farmworkers (78%) had H-2A visas. More farmworkers (64%) than non-farmworkers (41%) had ever used traditional healers. Among farmworkers, 21% (vs. 11% of non-farmworkers) had used curanderos, 54% (vs. 32%) sobadores, 43% (vs. 21%) hueseros, 11% (vs. 13%) yerberos, and 4% (vs. 6%) espiritualistas. More farmworkers had used a traditional healer in the past year (16% vs. 8%), but fewer had used this healer in the United States (4% vs. 8%). Among all participants, males (58.5%) more than females (41.4%) (P = .0214), and returning to Mexico annually (64.1%) more than who do not (45.1%) (P = .0086) had ever used any traditional healer. This pilot study indicates the need for further research that documents the use of traditional healers by Latino farmworkers with diverse visa statuses, from countries in addition to Mexico, and in other regions in the United States. This research should also delineate the specific illnesses and injuries for which Latino farmworkers use traditional healers.

Learning outcomes after traditional teaching methods were compared with problem-based learning (PBL) among fifth year medical students. Six students participated each in traditional teaching and PBL methods, respectively. Traditional teaching method involved PowerPoint (PPT) presentation and PBL included study on case scenario and discussion. Both methods were effective in improving performance of students. Postteaching, we did not find significant differences in learning outcomes between these two teaching methods. (1) Study was conducted with an intention to find out which method of learning is more effective; traditional or PBL. (2) To assess the level of knowledge and understanding in anemia/zoonotic diseases as against diabetes/hypertension. All the students posted from February 3, 2014, to March 14, 2014, participated in this study. Six students were asked to prepare and present a lecture (PPT) and subsequent week other six students were asked to present PBL. Both groups presented different topics. Since it was a pre- and post-test, same students were taken as control. To maintain uniformity and to avoid bias due cultural diversity, language etc., same questions were administered. After taking verbal consent, all 34 students were given pretest on anemia and zoonotic diseases. Then lecture (PPT) by six students on the same topic was given it followed by posttest questionnaire. Subsequent week pretest was conducted on hypertension and diabetes. Then case scenario presentation and discussion (PBL) was done by different six students followed by posttest. Both the methods were compared. Analysis was done manually and standard error of means and students t -test was used to find out statistical significance. We found statistically significant improvement in performance of students after PPT presentation as well as PBL. Both methods are equally effective. However, Pretest results of students in anemia and zoonotic diseases (Group A) were poor compared to pretest results of students in hypertension and diabetes (Group B). The students who participated in presentation did not influence their performance as they were covering a small part of the topic and there were no differences in their marks compared to other students. We did not find significant differences in outcome after teaching between PBL and traditional methods. Performances of students were poor in anemia and zoonotic diseases which need remedial teaching. Assessment may influence retention ability and performance.

Lelli, Vanessa R; Hickman, Ronald L; Savrin, Carol L; Peterson, Rachel A

2015-09-01

To examine if differences exist in the levels of autonomy and job satisfaction among primary care nurse practitioners (NPs) employed in retail clinics versus traditional primary care settings. Data were collected from 310 primary care NPs who attended the American Association of NP's 28th Annual Conference in June 2013. Participants completed a demographic form, the Misener NP Job Satisfaction Scale, and the Dempster Practice Behavior Scale. Overall, there were no differences in job satisfaction or autonomy among NPs by practice setting. Retail NPs felt less valued and were less satisfied with social interaction, but more satisfied with benefits compared to NPs in traditional settings. NPs working in retail clinics were less likely to have intentions to leave current position compared to NPs in traditional practice settings. The results of this study enhance our current understanding of the linkages between levels of autonomy, job satisfaction, and practice setting among primary care NPs. The findings of this descriptive study offer valuable insights for stakeholders devoted to the development of the primary care workforce and identify modifiable factors that may influence retention and turnover rates among NPs. ©2015 American Association of Nurse Practitioners.

Abstract Background Dietary notifications have been introduced recently for Alzheimer Disease (AD). In Iranian old medical manuscripts, there are some nutritional recommendations related to Nesyan (AD equivalent). The aim of this article was to compare dietary recommendations of Iranian traditional medicine (ITM) with novel medical outcomes. Methods 1) Searching for dietary recommendations and abstinences described in ITM credible manuscripts; 2) Extracting fatty components of ITM diet according to the database of the Department of Agriculture of the USA; 3) Statistical analysis of fatty elements of traditionally recommended foods via Mann-Whitney Test in comparison with elements of the abstinent ones; 4) Searching for AD dietary recommendations and abstinences which currently published in medical journals; 5) Comparing traditional and new dietary suggestions with each other. Results 1) Traditionally recommended foods are fattier than abstinent ones (P<0.001). There are meaningful differences between unsaturated fatty acids (UFAs) (P<0.001), saturated fatty acids (P<0.001), and cholesterol (P<0.05) of recommended foods and abstinent ones. 2) Traditionally recommended diet is also fattier than the abstinent diet (4.5 times); UFAs of the recommended diet is 11 times more than that of the abstinent one; it is the same story for cholesterol (1.4 times); 3) Recent studies show that diets with high amounts of UFAs have positive effects on AD; a considerable number of papers emphasizes on probable positive role of cholesterol on AD; 4) Traditional recommended diet is in agreement with recent studies. Conclusion ITM recommended diet which is full of unsaturated fatty acids and cholesterol can be utilized for complementary treatment of AD. PMID:26060643

This study explores consumers' acceptance of innovations in traditional cheese in France (n=120) and Norway (n=119). The respondents were presented with 16 photographs of a traditional cheese from their respective countries, varying according to six factors: pasteurisation, organic production, omega-3, packaging, price and appropriateness. For each of the scenarios the consumers indicated their willingness to buy the cheese on a nine-point scale. Results show that consumers' willingness to buy traditional cheese is highly driven by price, appropriateness and pasteurisation in both countries. However, on average consumers in the French sample prefer buying raw milk cheese, while consumers in the Norwegian sample prefer buying pasteurised cheese. These general trends are led by a pro-raw milk segment in France and a pro-pasteurised milk segment in Norway. Several interaction effects involving appropriateness are detected, indicating the importance of the consumption context on the acceptance of innovations in traditional cheese. On a general level, the results indicate that well-accepted innovations in traditional cheese are those that reinforce the traditional and authentic character of the product.

The embryo in ancient Rabbinic literature: between religious law and didactic narratives. An interpretive essay.

PubMed

Lepicard, Etienne

2010-01-01

At a time when bioethical issues are at the top of public and political agendas, there is a renewed interest in representations of the embryo in various religious traditions. One of the major traditions that has contributed to Western representations of the embryo is the Jewish tradition. This tradition poses some difficulties that may deter scholars, but also presents some invaluable advantages. These derive from two components, the search for limits and narrativity, both of which are directly connected with the manner in which Jewish tradition was constructed in Antiquity. The article accomplishes three goals: To introduce some central elements in ancient Rabbinic literature on the subject of the embryo and its representation; To present this body of literature as clearly as possible, noting some of the difficulties encountered by scholars who engage in its study; To explain how the literature's textuality came about, examining the particular sociopolitical circumstances of Judaism at that time, including the reasons for the delay in the production of scientific texts, transmitted as such, as compared to other philosophical or religious traditions. The article claims that these circumstances engendered a tradition peculiarly relevant for the study and teaching of medical ethics today.

In this study, the origin and causes of cooked traditional Chinese medicine powder were reviewed, and a comprehensive analysis was made for the time background of modern traditional Chinese medicine formula granules and the future development trend, in order to provide reference for application and promotion of traditional Chinese medicine formula granules. By reference to ancient medical books of previous dynasties, a system review was conducted for infancy, formation, maturity and transition of cooked traditional Chinese medicine powder, and a comprehensive analysis was made for the six factors of cooked traditional Chinese medicine powder's maturity in the Song Dynasty. Efforts were made to collect domestic and foreign research literatures of modern formula granules, understand the detailed development, and conduct an objective analysis of the current clinical application of modern formula granules. According to the comparative analysis for the application characteristics of cooked traditional Chinese medicine powder and modern formula granules, ①the popularity of cooked traditional Chinese medicine powder in the Song Dynasty has six factors: soaring numbers of medical students and medical practitioners, high medical expenses due to huge army, rapid population growth, frequent epidemics and increasing diseases, and insufficient finances of central and local governments. ②On the basis of clinical application characteristics of traditional Chinese medicine formula granules, traditional Chinese medicine formula granules contain extracted and concentrated effective components, which guarantee the curative effect, meet modern people's demands for "quick, simple and convenience" traditional Chinese medicine decoctions, show a relatively high cost performance; however, formula granules are restricted by their varieties and lack unified quality control standards, and single-extract formula granules have not synergy and attenuation effects of combined traditional Chinese medicine decoctions, which also restricts its clinical application and promotion. ③Both have advantages in the process of clinical application, and shall be used based on syndromes. In conclusion, traditional Chinese medicine formula granules do not have disadvantages of "difficult, complicated, turbid and disorderly" cooked traditional Chinese medicine powder, and solve such problems as "inflexibility, expensiveness, restriction, disorder and inefficacy", which is the important basis for promoting traditional Chinese medicine formula granules.

Objectives To compare traditional nurse triage (TNT) in a Pediatric Emergency Department (PED) to physician tele-presence (PTP). Methods Prospective, 2×2 crossover study with random assignment using a sample of walk-in patients seeking care in a PED at a large, tertiary care children’s hospital, from May 2012 to January 2013. Outcomes of triage times, documentation errors, triage scores, and survey responses were compared between TNT and PTP. Comparison between PTP to actual treating PED physicians regarding the accuracy of ordering blood and urine tests, throat cultures, and radiologic imaging was also studied. Results Paired samples t-tests showed a statistically significant difference in triage time between TNT and PTP (p=0.03), but no significant difference in documentation errors (p=0.10). Triage scores of TNT were 71% accurate, compared to PTP, which were 95% accurate. Both parents and children had favorable scores regarding PTP and the majority indicated they would prefer PTP again at their next PED visit. PTP diagnostic ordering was comparable to the actual PED physician ordering, showing no statistical differences. Conclusions Utilizing physician tele-presence technology to remotely perform triage is a feasible alternative to traditional nurse triage, with no clinically significant differences in time, triage scores, errors and patient and parent satisfaction.

2017-05-28

In this study, a total of 58 different kinds of nuruk (a traditional Korean fermentation starter) were prepared, including 46 kinds of restored nuruk from ancient documents. Each nuruk was evaluated by analysis of its saccharification power, and the enzyme activities of glucoamylase, α-amylase, β-amylase, protease, and β-glucanase. The range of saccharification power (sp) of the restored nuruk ranged between 85 and 565 sp. The diastatic enzymes, α-amylase, β-amylase, and glucoamylase, were significantly correlated to the saccharification power value; conversely, β-glucanase and protease did not have a correlative relationship with saccarification power. In addition, their brewing properties on chemical and organoleptic aspects of traditional alcoholic beverage production were compared. Each raw and supplementary material contained in nuruk showed its own unique characteristics on Korean alcoholic beverage brewing. For the first time, in this study, the traditional Korean nuruk types mentioned in ancient documents were restored using modernized production methods, and also characterized based on their brewing properties. Our results could be utilized as a basis for further study of traditional alcoholic beverages and their valuable microorganisms.

To compare time to ovulation, ovulation rates, and side effect profile of traditional and the stair-step protocol for ovulation induction using clomiphene citrate in women with polycystic ovary syndrome (PCOS). We performed a retrospective study of women seeking care for infertility with a diagnosis of PCOS at a university-based infertility clinic from July 2012 to July 2014. We included patients who were resistant to the initial starting dose of 50 mg clomiphene. The primary outcome was time to ovulation. Secondary outcomes included ovulation rates, clinical pregnancy rates, and mild and moderate-to-severe side effects based on dose. For the traditional protocol, higher doses of clomiphene were used each subsequent month if no ovulation occurred. For the stair-step protocol, higher doses of clomiphene were given 7 days after the last dose if no dominant follicles were seen on ultrasonography. Our study had 80% power to detect a 20% difference in ovulation. One hundred nine patients were included in the analysis with 66 (60.6%) in the traditional and 43 (39.4%) in the stair-step protocol. Age and body mass index were similar between groups. The time to ovulation was decreased in the stair-step protocol group compared with the traditional protocol group (23.1±0.9 days vs 47.5±6.3 days). Ovulation rates were increased in the stair-step group compared with the traditional group at 150 mg (16 [37%] vs 8 [12%], P=.004) and at 200 mg (9 [21%] vs 3 [5%], P=.01). Pregnancy rates were similar between groups once ovulation was achieved (12 [18.1%] vs 7 [16.3%], P=.08). The stair-step protocol had an increased incidence of mild side effects (vasomotor flushes, headaches, gastrointestinal disturbance, mastalgia, changes in mood; 18 [41%] vs 8 [12%]), but there was no difference in the incidence of severe side effects (headaches, visual disturbances). For women with PCOS, the stair-step clomiphene protocol is associated with decreased time to ovulation and increased ovulation rates at higher doses when compared with the traditional protocol.

The discovery of moist environment dressings as alternatives to the traditional treatments based on exposing wounds to air, opened new expectations for the care and treatment of chronic wounds. Over the years, these expectations have led to the availability of new moist environment dressings which have made it possible to improve the care provided to patients suffering this kind of wounds, as well as providing important reasons to weigh in terms of cost-benefit-effectiveness at the time of selecting which type of treatment should be employed. The lack of comparative analysis among traditional treatments and moist environment treatments for chronic wounds among patients receiving primary health care led the authors to perform an analysis comparing these aforementioned options of treatment on patients suffering venous leg ulcers or pressure ulcers. The authors designed a Randomized Clinical Trial involving patients receiving ambulatory care in order to compare the effectiveness and cost-benefit of traditional versus moist environment dressing during the treatment of patients suffering stage II or III pressure ulcers or venous leg ulcers. In this trial, variables related to effectiveness of both treatments, as well as their costs were analyzed. 70 wounds were included in this Randomized Clinical Trial, 41 were venous leg ulcers of which 21 received a moist environment treatment while 20 received traditional cure, the other 29 wounds were pressure ulcers of which 15 received moist environment dressings treatment and 14 received traditional dressings. No statistically significant differences were found among the defining variables for these lesions in either group under treatment. In the venous leg ulcer study group, the authors conclusions were an average of 18.13 days, 16.33 treatment sessions and a cost of 10,616 pesetas to heal one square centimeter of the initial surface area of a wound on patients treated with traditional treatment compared to an average of 18.22 days, 4.54 treatment sessions and a cost of 2409 pesetas to heal one square centimeter of the initial surface area of a wound on patients treated with moist environment dressings. In the pressure ulcers study group, the authors conclusions were an average of 12.18 days, 12.1 treatment sessions and a cost of 15,490 pesetas to heal one square centimeter of the initial surface area of a wound on patients treated with traditional treatment compared to an average of 7.12 days, 1.86 treatment sessions and a cost of 2610 pesetas to heal one square centimeter of the initial surface area of a wound on patients treated with moist environment dressings. The results of this randomized clinical trial demosntrated that the moist environment treatment group was more effective and had a better cost-benefit ratio than the traditional treatment group in the treatment of pressure ulcers and venous leg ulcers on patients cared for by nursing personnel in primary health care centers all of which agrees with publications consulted by authors.

A cesarean section rate of up to 19.4% is reported worldwide. Surgical site infection occurs with rates of up to 13.5%. Plastic-sheath wound retractors show reduced rates of surgical site infections in abdominal surgery. There is limited evidence in women having cesarean sections. This study evaluates the use of the Alexis(®) O C-Section Retractor in the prevention of surgical site infection in patients undergoing their first planned cesarean section compared to the traditional Collins self-retaining metal retractor. A single center, prospective, randomized, controlled, observational trial. The primary outcome is surgical site infection as defined by the Centers for Disease Control and Prevention. The secondary outcomes included intraoperative surgical parameters, postoperative pain scores and the short and long-term satisfaction with wound healing. From October 2013 to December 2015 at the Charité University Hospital, Berlin. 98 patients to the Alexis(®) O C-Section Retractor group and 100 to the traditional Collins self-retaining metal retractor group. A statistically significant reduction in the rate of surgical site infections, when the Alexis(®) O C-Section Retractor was used for wound retraction compared to the traditional Collins metal self-retaining wound retractor, 1% vs. 8% (RR 7.84, 95% CI (2.45-70.71) p=0.035). The use of plastic-sheath wound retractors compared to the traditional self-retaining metal retractor in low risk women, having the first cesarean section is associated with a significantly reduced risk of surgical site infection.

In an era of mandatory bundled payments for total joint replacement, accurate analysis of the cost of procedures is essential for orthopaedic surgeons and their institutions to maintain viable practices. The purpose of this study was to compare traditional accounting and time-driven activity-based costing (TDABC) methods for estimating the total costs of total hip and knee arthroplasty care cycles. We calculated the overall costs of elective primary total hip and total knee replacement care cycles at our academic medical center using traditional and TDABC accounting methods. We compared the methods with respect to the overall costs of hip and knee replacement and the costs for each major cost category. The traditional accounting method resulted in higher cost estimates. The total cost per hip replacement was $22,076 (2014 USD) using traditional accounting and was $12,957 using TDABC. The total cost per knee replacement was $29,488 using traditional accounting and was $16,981 using TDABC. With respect to cost categories, estimates using traditional accounting were greater for hip and knee replacement, respectively, by $3,432 and $5,486 for personnel, by $3,398 and $3,664 for space and equipment, and by $2,289 and $3,357 for indirect costs. Implants and consumables were derived from the actual hospital purchase price; accordingly, both methods produced equivalent results. Substantial cost differences exist between accounting methods. The focus of TDABC only on resources used directly by the patient contrasts with the allocation of all operating costs, including all indirect costs and unused capacity, with traditional accounting. We expect that the true costs of hip and knee replacement care cycles are likely somewhere between estimates derived from traditional accounting methods and TDABC. TDABC offers patient-level granular cost information that better serves in the redesign of care pathways and may lead to more strategic resource-allocation decisions to optimize actual operating margins.

The application and development of traditional percutaneous microwave coagulation therapy (PMCT) has been limited by high shaft temperature. The "air-cooled" PMCT is the newest advancement. This study was to compare shaft temperature related treatment efficacy between "air-cooled" PMCT and traditional PMCT. Two pigs underwent traditional PMCT, and "air-cooled" PMCT at 80 W for 10 min separately. Skin injury, surface temperature of guide-needle, charring tissue sticking to the shaft, and lesion shape in 2 pigs were compared. Five patients with liver tumor received traditional PMCT, and 8 patients with liver tumor received "air-cooled" PMCT. Feeling of pain, skin injury, charring tissue sticking to the shaft, local therapeutic efficacy, and recurrence of these 2 groups of patients were compared. In the pig underwent traditional PMCT, surface temperature of guide-needle reached 119-160 Centigrade; skin burn around puncture points was serious; charring tissue stuck to the front of electrodes; a trail sign was observed in coagulated lesion. In the pig underwent "air-cooled" PMCT, surface temperature of guide-needle was 28.8-39.9 Centigrade; no skin injury was found around puncture points; no charring tissue stuck to the front of electrodes; no obvious trail sign was observed in coagulated lesion. In 5 patients received traditional PMCT, 3 had skin injury; 2 had charring tissue stuck to the front of electrode; all felt moderate or serious epigastric pain lasted for 1-8 weeks; 4 had complete coagulation; 1 had local recurrence. In 8 patients received "air-cooled" PMCT, no one had skin injury, and charring tissue stuck to "air-cooled" electrode; 4 felt slight epigastric pain within 1 week; all had complete coagulation; no local recurrence was found. The technique of "air-cooled" electrode may decrease temperature of shaft safely and reliably, and eliminate side effects arose from high temperature of shaft. Treatment efficacy of "air-cooled" PMCT is better than that of traditional PMCT.

In recent times, the changes occurring in the social role of women and men have been observed. Traditionally, the dominating social role of the woman was as housewife, and that of the man was focused on work and family maintenance. Nowadays, the social role of women is evolving in the direction of taking a profession, while increasingly men are taking care of the household. The main goal of the studies presented here was to verify how the activation of different social roles (traditional or non-traditional) may be reflected in women's financial and consumer choices. Three experimental studies were conducted. In the first study (n = 195 females), three different social roles of women - professional (non-traditional), housewife (traditional) and neutral (control) - were activated. The results showed that activating women's non-traditional social role increased their tendency to invest and decreased their propensity to save money compared to the activation of the traditional or neutral social role. The goal of the second study (n = 196 females) was to check whether, despite there being no differences in the level of consumption in the first study, can any differences be observed in the preference for the type of products chosen for consumption. The results showed that activating the non-traditional social role raised the propensity to spend funds on products and services for individual use and reduced the willingness to buy goods for collective use (shared with other members of the household). The purpose of the third study (n = 90 females) was to examine how different images of women appearing in advertisements may affect women's judgments of the advertised product. Women who watched the ad with woman in the non-traditional social role estimated the product quality, look, color and price higher that participants exposed to the advertisement presenting the woman in traditional or neutral social role. The present studies give some evidence that the new, non-traditional social role of women that is often presented in the media may affect women's everyday financial choices and judgments of products.

The Economic Botany Data Collection Standard (EBDCS) has been successfully followed by ethnobotanists investigating plant uses in many parts of the world. However, we have encountered some cases in our study of traditional medicine where the standard seems incomplete and inaccurate when it is applied to plant uses of rural or indigenous societies in developing countries. We propose two categories to be added to the EBDCS: Cultural Diseases and Disorders, and Ritual/Magical Uses. Adding these categories, we believe will give a more accurate insight into traditional medicine and will contribute to developing an integrative ethnomedicinal data collection protocol, which will make ethnomedicinal studies more comparable.

This quasi-experimental study, with a control group and experimental group, compares the effectiveness of virtual reality simulators on developing phlebotomy skills of nursing students with the effectiveness of traditional methods of teaching. Performance of actual phlebotomy on a live client was assessed after training, using a standardized form. Findings showed that students who were exposed to the virtual reality simulator performed better in the following performance metrics: pain factor, hematoma formation, and number of reinsertions. This study confirms that the use of the virtual reality-based system to supplement the traditional method may be the optimal program for training.

2012-12-01

The main problem in the industrial production process of thick EPM/EPDM elements is constituted by the different temperatures which undergo internal (cooler) and external regions. Indeed, while internal layers remain essentially under-vulcanized, external coating is always over-vulcanized, resulting in an overall average tensile strength insufficient to permit the utilization of the items in several applications where it is required a certain level of performance. Possible ways to improve rubber output mechanical properties include a careful calibration of exposition time and curing temperature in traditional heating or a vulcanization through innovative techniques, such as microwaves. In the present paper, a comprehensive numerical model able to give predictions on the optimized final mechanical properties of vulcanized 2D and 3D thick rubber items is presented and applied to a meaningful example of engineering interest. A detailed comparative numerical study is finally presented in order to establish pros and cons of traditional vulcanization vs microwaves curing.

Objective. To compare learning outcomes achieved from a pharmaceutical calculations course taught in a traditional lecture (lecture model) and a flipped classroom (flipped model). Methods. Students were randomly assigned to the lecture model and the flipped model. Course instructors, content, assessments, and instructional time for both models were equivalent. Overall group performance and pass rates on a standardized assessment (Pcalc OSCE) were compared at six weeks and at six months post-course completion. Results. Student mean exam scores in the flipped model were higher than those in the lecture model at six weeks and six months later. Significantly more students passed the OSCE the first time in the flipped model at six weeks; however, this effect was not maintained at six months. Conclusion. Within a 6 week course of study, use of a flipped classroom improves student pharmacy calculation skill achievement relative to a traditional lecture andragogy. Further study is needed to determine if the effect is maintained over time.

Is the relationship between pattern recall and decision-making influenced by anticipatory recall?

PubMed

Gorman, Adam D; Abernethy, Bruce; Farrow, Damian

2013-01-01

The present study compared traditional measures of pattern recall to measures of anticipatory recall and decision-making to examine the underlying mechanisms of expert pattern perception and to address methodological limitations in previous studies where anticipatory recall has generally been overlooked. Recall performance in expert and novice basketball players was measured by examining the spatial error in recalling player positions both for a target image (traditional recall) and at 40-ms increments following the target image (anticipatory recall). Decision-making performance was measured by comparing the participant's response to those identified by a panel of expert coaches. Anticipatory recall was observed in the recall task and was significantly more pronounced for the experts, suggesting that traditional methods of spatial recall analysis may not have provided a completely accurate determination of the full magnitude of the experts' superiority. Accounting for anticipatory recall also increased the relative contribution of recall skill to decision-making accuracy although the gains in explained variance were modest and of debatable functional significance.

Traditional birth attendants (TBAs) are likely to deliver lower quality maternity care compared to professional health workers. It is important to characterize women who are assisted by TBAs in order to design interventions specific to such groups. We thus conducted a study to assess if socio-economic status and demographic factors are associated with having childbirth supervised by traditional birth attendants in Iraq. Iraqi Multiple Indicator Cluster Survey (MICS) data for 2000 were used. We estimated frequencies and proportions of having been delivered by a traditional birth attendant and other social characteristics. Logistic regression analysis was used to assess the association between having been delivered by a TBA and wealth, area of residence (urban versus rural), parity, maternal education and age. Altogether 22,980 women participated in the survey, and of these women, 2873 had delivery information and whether they were assisted by traditional birth attendants (TBAs) or not during delivery. About 1 in 5 women (26.9%) had been assisted by TBAs. Compared to women of age 35 years or more, women of age 25-34 years were 22% (AOR = 1.22, 95%CI [1.08, 1.39]) more likely to be assisted by TBAs during delivery. Women who had no formal education were 42% (AOR = 1.42, 95%CI [1.22, 1.65]) more likely to be delivered by TBAs compared to those who had attained secondary or higher level of education. Women in the poorest wealth quintile were 2.52 (AOR = 2.52, 95%CI [2.14, 2.98]) more likely to be delivered by TBAs compared to those in the richest quintile. Compared to women who had 7 or more children, those who had 1 or 2 were 28% (AOR = 0.72, 95%CI [0.59, 0.87]) less likely to be delivered by TBAs. Findings from this study indicate that having delivery supervised by traditional birth attendants was associated with young maternal age, low education, and being poor. Meanwhile women having 1 or 2 children were less likely to be delivered by TBAs. These factors should be considered in the design of interventions to reduce the rate of deliveries assisted by TBAs in favour of professional midwives, and consequently reduce maternal and neonatal mortality rates and other adverse events.

Non-radioisotopic local lymph node assay (LLNA) employing 5-bromo-2'-deoxyuridine (BrdU) with flow cytometry (FACS) or immunohistochemistry (IHC) is gaining attention due to a regulatory issue of using radioisotope, (3)H-thymidine, in vivo in traditional LLNA. In this study, to compare the performance of these non-radioisotopic endpoints, 7 chemicals with known sensitizing potencies were examined in LLNA. Mice were topically treated with chemicals or vehicle on both ears for 3 days. After intraperitoneal injection of BrdU, bilateral lymph nodes were isolated separately and undergone respectively, FACS or IHC to determine BrdU incorporated lymph node cells (LNCs). Weight and histology of treated ears were also examined to evaluate chemical-induced edema and irritation. Both FACS and IHC could successively identify the skin sensitizers from non-sensitizers. Comparison of FACS and IHC with traditional LLNA revealed that FACS has a higher sensitivity although both assays produced comparable sensitivity and performance to traditional LLNA. In conclusion, non-radioisotopic LLNA using FACS and IHC can successfully detect sensitizers with a good correlation to traditional LLNA. Notably, FACS showed almost equivalent sensitivity and accuracy to traditional LLNA. 2009 Elsevier Ireland Ltd. All rights reserved.

The aim of this study was to compare the effectiveness of oral health counseling sessions with traditional oral hygiene education in orthodontic patients with fixed appliances. randomised control trial with experimental and control group. A group of 99 adolescents with fixed orthodontic appliances were randomly assigned to oral health counseling (experimental) or traditional health education (control) group. Subjects in the control group received verbal instructions and a demonstration of the modified Bass brushing technique on a model. The experimental group also received the verbal information with demonstration on the model and in addition a personalised 40-minutes counseling session on oral hygiene. Plaque Index (PI) and gingivitis (G) were recorded before, 1 and 6 months after the counseling session/traditional education. Oral health counseling and traditional education improved the oral hygiene of orthodontic patients. PI values were significantly lower after 6 months compared to the baseline in both groups, but the prevalence of gingival inflammation remained significantly lower only in the experimental group. Oral health counseling increased plaque removal efficacy and control of gingival inflammation. The efficiency of counseling and traditional education was similar. Counseling is a promising approach that warrants further attention in a variety of dental contexts.

Virtual reality simulators allow trainees to practice techniques without consequences, reduce potential risk associated with training, minimize animal use, and help to develop standards and optimize procedures. Current intravenous (IV) catheter placement training methods utilize plastic arms, however, the lack of variability can diminish the educational stimulus for the student. This study compares the effectiveness of an interactive, multimedia, virtual reality computer IV catheter simulator with a traditional laboratory experience of teaching IV venipuncture skills to both nursing and medical students. A randomized, pretest-posttest experimental design was employed. A total of 163 participants, 70 baccalaureate nursing students and 93 third-year medical students beginning their fundamental skills training were recruited. The students ranged in age from 20 to 55 years (mean 25). Fifty-eight percent were female and 68% percent perceived themselves as having average computer skills (25% declaring excellence). The methods of IV catheter education compared included a traditional method of instruction involving a scripted self-study module which involved a 10-minute videotape, instructor demonstration, and hands-on-experience using plastic mannequin arms. The second method involved an interactive multimedia, commercially made computer catheter simulator program utilizing virtual reality (CathSim). The pretest scores were similar between the computer and the traditional laboratory group. There was a significant improvement in cognitive gains, student satisfaction, and documentation of the procedure with the traditional laboratory group compared with the computer catheter simulator group. Both groups were similar in their ability to demonstrate the skill correctly. CONCLUSIONS; This evaluation and assessment was an initial effort to assess new teaching methodologies related to intravenous catheter placement and their effects on student learning outcomes and behaviors. Technology alone is not a solution for stand alone IV catheter placement education. A traditional learning method was preferred by students. The combination of these two methods of education may further enhance the trainee's satisfaction and skill acquisition level.

Telecommuniciation technologies, including audio and videoconferencing facilities, afford geographically dispersed health professionals the opportunity to connect and collaborate with others. Recognised for enabling tele-consultations and tele-collaborations between teams of health care professionals and their patients, these technologies are also well suited to the delivery of distance learning programs, known as tele-learning. To determine whether tele-learning delivery methods achieve equivalent learning outcomes when compared with traditional face-to-face education delivery methods. A systematic literature review was commissioned by the NSW Ministry of Health to identify results relevant to programs applying tele-learning delivery methods in the provision of education to health professionals. The review found few studies that rigorously compared tele-learning with traditional formats. There was some evidence, however, to support the premise that tele-learning models achieve comparable learning outcomes and that participants are generally satisfied with and accepting of this delivery method. The review illustrated that tele-learning technologies not only enable distance learning opportunities, but achieve comparable learning outcomes to traditional face-to-face models. More rigorous evidence is required to strengthen these findings and should be the focus of future tele-learning research.

Context-based curriculum reforms in chemistry education are thought to bring greater diversity to the ways in which chemistry teachers organize their teaching. First and foremost, students are expected to perceive this diversity. However, empirical research on how students perceive their teacher's teaching in context-based chemistry classrooms, and whether this teaching differs from traditional chemistry lessons, is scarce. This study aims to develop our understanding of what teaching looks like, according to students, in context-based chemistry classrooms compared with traditional chemistry classrooms. As such, it might also provide a better understanding of whether teachers implement and attain the intentions of curriculum developers. To study teacher behaviour we used three theoretical perspectives deemed to be important for student learning: a content perspective, a learning activities perspective, and an interpersonal perspective. Data were collected from 480 students in 24 secondary chemistry classes in the Netherlands. Our findings suggest that, according to the students, the changes in teaching in context-based chemistry classrooms imply a lessening of the emphasis on fundamental chemistry and the use of a teacher-centred approach, compared with traditional chemistry classrooms. However, teachers in context-based chemistry classrooms seem not to display more 'context-based' teaching behaviour, such as emphasizing the relation between chemistry, technology, and society and using a student-centred approach. Furthermore, students in context-based chemistry classrooms perceive their teachers as having less interpersonal control and showing less affiliation than teachers in traditional chemistry classrooms. Our findings should be interpreted in the context of former and daily experiences of both teachers and students. As only chemistry is reformed in the schools in which context-based chemistry is implemented, it is challenging for both students and teachers to deal with these reforms.

Automated Cellient(™) cytoblocks: better, stronger, faster?

Cytoblocks (CBs), or cell blocks, provide additional morphological detail and a platform for immunocytochemistry (ICC) in cytopathology. The Cellient(™) system produces CBs in 45 minutes using methanol fixation, compared with traditional CBs, which require overnight formalin fixation. This study compares Cellient and traditional CB methods in terms of cellularity, morphology and immunoreactivity, evaluates the potential to add formalin fixation to the Cellient method for ICC studies and determines the optimal sectioning depth for maximal cellularity in Cellient CBs. One hundred and sixty CBs were prepared from 40 cytology samples (32 malignant, eight benign) using four processing methods: (A) traditional; (B) Cellient (methanol fixation); (C) Cellient using additional formalin fixation for 30 minutes; (D) Cellient using additional formalin fixation for 60 minutes. Haematoxylin and eosin-stained sections were assessed for cellularity and morphology. ICC was assessed on 14 cases with a panel of antibodies. Three additional Cellient samples were serially sectioned to determine the optimal sectioning depth. Scoring was performed by two independent, blinded reviewers. For malignant cases, morphology was superior with Cellient relative to traditional CBs (P < 0.001). Cellularity was comparable across all methods. ICC was excellent in all groups and the addition of formalin at any stage during the Cellient process did not influence the staining quality. Serial sectioning through Cellient CBs showed optimum cellularity at 30-40 μm with at least 27 sections obtainable. Cellient CBs provide superior morphology to traditional CBs and, if required, formalin fixation may be added to the Cellient process for ICC. Optimal Cellient CB cellularity is achieved at 30-40 μm, which will impact on the handling of cases in daily practice. © 2014 John Wiley & Sons Ltd.

Traditional and gestational surrogate mothers assist infertile couples by carrying their children. In 2005, a meta-analysis on surrogacy was conducted but no study had examined empathy and maternal-foetal attachment of surrogate mothers. Assessments of surrogate mothers show no sign of psychopathology, but one study showed differences on several MMPI-2 scales compared to a normative sample: surrogate mothers identified with stereotypically masculine traits such as assertiveness and competition. They had a higher self-esteem and lower levels of anxiety and depression. To determine if there is a difference in empathy and maternal-foetal attachment of surrogate mothers compared to a comparison group of mothers. Three groups of European traditional and gestational surrogate mothers (n=10), Anglo-Saxon traditional and gestational surrogate mothers (n=34) and a European normative sample of mothers (n=32) completed four published psychometric instruments: the Interpersonal Reactivity Index (empathy index), the Hospital Anxiety and Depressions Scale and the MC20, a social desirability scale. Pregnant surrogate mothers filled the Maternal Antenatal Attachment Scale (n=11). Statistical non-parametric analyses of variance were conducted. Depending on cultural background, surrogate mothers present differences in terms of empathy, anxiety and depression, social desirability and quality of attachment to the foetus compared to a normative sample. Environment plays a role for traditional and gestational surrogacy. Surrogate mothers of both groups are less anxious and depressed than normative samples. Maternal-foetal attachment is strong with a slightly lower quality of attachment. Surrogate mother's empathy indexes are similar to normative samples, sometimes higher.

2015-01-01

Local anesthetic injection is one of the most anxiety- provoking procedure for both children and adult patients in dentistry. A computerized system for slow delivery of local anesthetic has been developed as a possible solution to reduce the pain related to the local anesthetic injection. The present study was conducted to evaluate and compare pain perception rates in pediatric patients with computerized system and traditional methods, both objectively and subjectively. It was a randomized controlled study in one hundred children aged 8-12 years in healthy physical and mental state, assessed as being cooperative, requiring extraction of maxillary primary molars. Children were divided into two groups by random sampling - Group A received buccal and palatal infiltration injection using Wand, while Group B received buccal and palatal infiltration using traditional syringe. Visual Analog scale (VAS) was used for subjective evaluation of pain perception by patient. Sound, Eye, Motor (SEM) scale was used as an objective method where sound, eye and motor reactions of patient were observed and heart rate measurement using pulse oximeter was used as the physiological parameter for objective evaluation. Patients experienced significantly less pain of injection with the computerized method during palatal infiltration, while less pain was not statistically significant during buccal infiltration. Heart rate increased during both buccal and palatal infiltration in traditional and computerized local anesthesia, but difference between traditional and computerized method was not statistically significant. It was concluded that pain perception was significantly more during traditional palatal infiltration injection as compared to computerized palatal infiltration, while there was no difference in pain perception during buccal infiltration in both the groups.

Programming PHREEQC calculations with C++ and Python a comparative study

2011-01-01

The new IPhreeqc module provides an application programming interface (API) to facilitate coupling of other codes with the U.S. Geological Survey geochemical model PHREEQC. Traditionally, loose coupling of PHREEQC with other applications required methods to create PHREEQC input files, start external PHREEQC processes, and process PHREEQC output files. IPhreeqc eliminates most of this effort by providing direct access to PHREEQC capabilities through a component object model (COM), a library, or a dynamically linked library (DLL). Input and calculations can be specified through internally programmed strings, and all data exchange between an application and the module can occur in computer memory. This study compares simulations programmed in C++ and Python that are tightly coupled with IPhreeqc modules to the traditional simulations that are loosely coupled to PHREEQC. The study compares performance, quantifies effort, and evaluates lines of code and the complexity of the design. The comparisons show that IPhreeqc offers a more powerful and simpler approach for incorporating PHREEQC calculations into transport models and other applications that need to perform PHREEQC calculations. The IPhreeqc module facilitates the design of coupled applications and significantly reduces run times. Even a moderate knowledge of one of the supported programming languages allows more efficient use of PHREEQC than the traditional loosely coupled approach.

Virtual reality (VR) training, a virtual environment commonly generated by computer systems, may enhance the therapeutic efficacy of functional rehabilitation programmes. The aim of this study was to investigate the efficacy of a VR assisted intervention (VRAI) versus traditional rehabilitation intervention (TRI) on functional ankle instability (FAI). A single-blind randomized controlled study was conducted with 10 subjects for each group. The VRAI was conducted with the Nintendo Wii Fit Plus, whilst the TRI was conducted with a series of exercises with theraband. The muscle strength change of the two groups and the difference between pre and post interventions for each group were compared. The VRAI group had less improvement in the muscle strength of all ankle motions than did the TRI group (p > .05). The VRAI group had a greater improvement in muscle strength of plantar flexion than other motions, whilst the TRI group had an improvement in muscle strength of all ankle motions (p < .05). The effects of VR training for the condition of FAI were not comparable to conventional training. However, VR training may be added to the conventional training programme as an optional for the condition of FAI. Implications for Rehabilitation Functional ankle instability (FAI) is subjective feelings of ankle instability resulting from proprioceptive and neuromuscular deficits in which individuals may experience "giving way" condition of the ankle. Therapeutic applications of virtual reality (VR) may be comparable to traditional rehabilitation interventions (TRI) in the rehabilitation of individuals with FAI. However, there is no definitive evidence for the issue. Integrating low-cost VR into functional rehabilitation programme can provide insight into an issue of whether it can be replaced with traditional therapeutic approaches. Although, the efficacy of VR application on strengthening muscles is unable to compare to traditional strengthening programmes, it may be considered an optional treatment based on the proprioceptive improvements.

Aim In Australia, trampolines contribute approximately one-quarter of all childhood play-equipment injuries. The purpose of this study was to gather and evaluate injury data from a nontraditional, ‘soft-edged’, consumer trampoline in which the equipment injury sources have been designed out. Methods A survey was undertaken in Queensland and New South Wales. The manufacturer of the nontraditional trampoline provided the University of Technology, Sydney, with their Australian customer database. Injury data were gathered in a pilot study by phone interview, then in a full study through an email survey. Results from 3817 respondents were compared with earlier Australian and US data from traditional trampolines gathered from emergency departments. Results A significantly lower proportion of the injuries caused by falling off or striking the equipment was found for this new design when compared with traditional trampolines both in Australia and in the USA. The age of children being injured on trampolines in Australia was found to be markedly lower than in North America. Conclusions This research indicates that with appropriate design the more severe injuries on traditional trampolines can be significantly reduced. PMID:22404557

The use of e-learning, defined as any educational intervention mediated electronically via the Internet, has steadily increased among health professionals worldwide. Several studies have attempted to measure the effects of e-learning in medical practice, which has often been associated with large positive effects when compared to no intervention and with small positive effects when compared with traditional learning (without access to e-learning). However, results are not conclusive. To assess the effects of e-learning programmes versus traditional learning in licensed health professionals for improving patient outcomes or health professionals' behaviours, skills and knowledge. We searched CENTRAL, MEDLINE, Embase, five other databases and three trial registers up to July 2016, without any restrictions based on language or status of publication. We examined the reference lists of the included studies and other relevant reviews. If necessary, we contacted the study authors to collect additional information on studies. Randomised trials assessing the effectiveness of e-learning versus traditional learning for health professionals. We excluded non-randomised trials and trials involving undergraduate health professionals. Two authors independently selected studies, extracted data and assessed risk of bias. We graded the certainty of evidence for each outcome using the GRADE approach and standardised the outcome effects using relative risks (risk ratio (RR) or odds ratio (OR)) or standardised mean difference (SMD) when possible. We included 16 randomised trials involving 5679 licensed health professionals (4759 mixed health professionals, 587 nurses, 300 doctors and 33 childcare health consultants).When compared with traditional learning at 12-month follow-up, low-certainty evidence suggests that e-learning may make little or no difference for the following patient outcomes: the proportion of patients with low-density lipoprotein (LDL) cholesterol of less than 100 mg/dL (adjusted difference 4.0%, 95% confidence interval (CI) -0.3 to 7.9, N = 6399 patients, 1 study) and the proportion with glycated haemoglobin level of less than 8% (adjusted difference 4.6%, 95% CI -1.5 to 9.8, 3114 patients, 1 study). At 3- to 12-month follow-up, low-certainty evidence indicates that e-learning may make little or no difference on the following behaviours in health professionals: screening for dyslipidaemia (OR 0.90, 95% CI 0.77 to 1.06, 6027 patients, 2 studies) and treatment for dyslipidaemia (OR 1.15, 95% CI 0.89 to 1.48, 5491 patients, 2 studies). It is uncertain whether e-learning improves or reduces health professionals' skills (2912 health professionals; 6 studies; very low-certainty evidence), and it may make little or no difference in health professionals' knowledge (3236 participants; 11 studies; low-certainty evidence).Due to the paucity of studies and data, we were unable to explore differences in effects across different subgroups. Owing to poor reporting, we were unable to collect sufficient information to complete a meaningful 'Risk of bias' assessment for most of the quality criteria. We evaluated the risk of bias as unclear for most studies, but we classified the largest trial as being at low risk of bias. Missing data represented a potential source of bias in several studies. When compared to traditional learning, e-learning may make little or no difference in patient outcomes or health professionals' behaviours, skills or knowledge. Even if e-learning could be more successful than traditional learning in particular medical education settings, general claims of it as inherently more effective than traditional learning may be misleading.

Periodontal profile class is associated with prevalent diabetes, coronary heart disease, stroke, and systemic markers of C-reactive protein and interleukin-6.

This paper focuses on the Periodontal Profile Class (PPC) System that may be more informative and representative of periodontitis phenotypes than current case definitions of periodontitis. This study illustrates the unique aspects of the PPC compared with other periodontal indices for studying associations between periodontal disease and prevalent systemic conditions. We computed odds ratios and 95% confidence intervals to compare associations between periodontal disease and prevalent systemic conditions using our new PPC and two traditional indices. We used the Bayesian Information Criterion (BIC) to determine the fit of the model and the magnitude of the contribution attributable to periodontal disease beyond traditional risk factors. The Atherosclerosis Risk in Communities (ARIC) Study (1996-1998) results were compared with results from the combined National Health and Nutrition Examination Survey 2009-2014 datasets. In the ARIC Study, high gingival inflammation, tooth loss, severe tooth loss, and severe disease PPC components were significantly associated with diabetes, coronary heart disease (CHD), high-sensitivity C-reactive protein, and interleukin (IL)-6, while only severe disease was associated with stroke. Severe disease was associated with CHD using the Centers for Disease Control/American Academy of Periodontology index, and the European Periodontal index was associated with CHD and IL-6. The addition of the PPC to traditional variables associated with prevalent diabetes, stroke, CHD, and systemic measures of inflammation resulted in very strong improvement of the overall models, while the traditional indices were less likely to be associated and, if present, the associations were weaker. The PPC system provides specific insight into the individuals and periodontal characteristics of the phenotype that are associated with systemic conditions that may be useful in designing treatment interventions. © 2018 American Academy of Periodontology.

Critical thinking and self-confidence are imperative to success in clinical practice. Educators should use teaching strategies that will help students enhance their critical thinking and self-confidence in complex content such as electrocardiogram interpretation. Therefore, teaching electrocardiogram interpretation to students is important for nurse educators. This study compares the effect of simulation-based and traditional teaching methods on the critical thinking and self-confidence of students during electrocardiogram interpretation sessions. Thirty undergraduate nursing students volunteered to participate in this study. The participants were divided into intervention and control groups, which were taught respectively using the simulation-based and traditional teaching programs. All of the participants were asked to complete the study instrumentpretest and posttest to measure their critical thinking and self-confidence. Improvement was observed in the control and experimental groups with respect to critical thinking and self-confidence, as evidenced by the results of the paired samples t test and the Wilcoxon signed-rank test (p < .05). However, the independent t test and Mann-Whitney U test indicate that the difference between the two groups was not significant (p > .05). This study evaluated an innovative simulation-based teaching method for nurses. No significant differences in outcomes were identified between the simulator-based and traditional teaching methods, indicating that well-implemented educational programs that use either teaching method effectively promote critical thinking and self-confidence in nursing students. Nurse educators are encouraged to design educational plans with clear objectives to improve the critical thinking and self-confidence of their students. Future research should compare the effects of several teaching sessions using each method in a larger sample.

The traditional lecturing method is still one of the most common forms of delivering content to students in dental education, but innovative learning technologies have the potential to improve the effectiveness and quality of teaching dental students. What challenges instructors is the extent to which these learning tools have a direct impact on student learning outcomes. The aim of this study was to assess the impact of a voice-over screen-captured learning tool by identifying a positive, nil, or negative impact on student learning as well as student engagement (affective, behavioral, and cognitive) when compared to the traditional face-to-face lecture. Extraneous variables thought to impact student learning were controlled by the use of baseline measures as well as random assignment of second-year dental students to one of two teaching conditions: voice-over screen-captured presentation delivered online and the traditional classroom lecture. A total of 28 students enrolled in the preclinical course in endodontics at a Canadian dental school participated in the study, 14 in each of the two teaching conditions. The results showed that, in most cases, the students who experienced the online lecture had somewhat higher posttest scores and perceived satisfaction levels than those in the face-to-face lecture group, but the differences did not achieve statistical significance except for their long-term recognition test scores. This study found that the students had comparable learning outcomes whether they experienced the face-to-face or the online lecture, but that the online lecture had a more positive impact on their long-term learning. The controls for extraneous variables used in this study suggest ways to improve research into the comparative impact of traditional and innovative teaching methods on student learning outcomes.

The nested case-control study design (or the case-control in a cohort study) is described here as a new study design used in safe evaluation of post-marketing traditional Chinese medicine injection. In the nested case-control study, cases of a disease that occur in a defined cohort are identified and, for each, a specified number of matched controls is selected from among those in the cohort who have not developed the disease by the time of disease occurrence in the case. For many research questions, the nested case-control design potentially offers impressive reductions in costs and efforts of data collection and analysis compared with the full cohort approach, with relatively minor loss in statistical efficiency. The nested case-control design is particularly advantageous for studies in safe evaluation of post-marketing traditional Chinese medicine injection. Some examples of the application of nested case-control study were given.

In this paper, physico-chemical and structural properties of cut and cooked purple-flesh potato, green bean pods, and carrots have been studied. Three different cooking methods have been applied: traditional cooking (boiling water at 100 °C), cook-vide (at 80 and 90 °C) and sous-vide (at 80 °C and 90 °C). Similar firmness was obtained in potato applying the same cooking time using traditional cooking (100 °C), and cook-vide and sous-vide at 90 °C, while in green beans and carrots the application of the sous-vide (90 °C) required longer cooking times than cook-vide (90 °C) and traditional cooking (100 °C). Losses in anthocyanins (for purple-flesh potatoes) and ascorbic acid (for green beans) were higher applying traditional cooking. β-Carotene extraction increased in carrots with traditional cooking and cook-vide (P < 0.05). Cryo-SEM micrographs suggested higher swelling pressure of starch in potatoes cells cooked in contact with water, such as traditional cooking and cook-vide. Traditional cooking was the most aggressive treatment in green beans because the secondary walls were reduced compared with sous-vide and cook-vide. Sous-vide preserved organelles in the carrot cells, which could explain the lower extraction of β-carotene compared with cook-vide and traditional cooking. Sous-vide cooking of purple-flesh potato is recommended to maintain its high anthocyanin content. Traditional boiling could be recommended for carrots because increase β-carotenes availability. For green beans, cook-vide, and sous-vide provided products with higher ascorbic acid content. © 2015 Institute of Food Technologists®

The round window membrane (RWM)-intentioned approach is superior to the traditional bony cochleostomy (BC) approach in obtaining electrode placement within the scala tympani (ST). Cochlear implant outcome is influenced by several factors, including optimal placement and retention of the electrode array within the ST. The present study aimed to assess whether the RWM route is superior to a traditional BC for placement and retention of the electrode array in the ST. This was a prospective consecutive non-randomized comparison study. All patients were implanted with the Advanced Bionics 1J electrode array. The RWM approach (n = 32) was compared with a traditional BC group (n = 33). The outcome measure was the electrode position as judged within the scalar chambers at four points along the basal turn using postoperative computed tomography (CT). When the mean position scores were compared, the RWM-intentioned group had significantly more electrodes directed towards the ST compartment than the BC group (p < 0.001). The RWM electrodes achieved 94% ST retention compared with 64% for the BC group (p < 0.05). All electrodes stayed in the ST in the RWM group, whereas in the BC group 9% crossed from the ST to the scala vestibuli.

OBJECTIVE: To evaluate the incremental cost-effectiveness of a system-based approach for the management of neonatal jaundice and the prevention of kernicterus in term and late-preterm (≥35 weeks) infants, compared with the traditional practice based on visual inspection and selected bilirubin testing. STUDY DESIGN: Two hypothetical cohorts of 150,000 term and late-preterm neonates were used to compare the costs and outcomes associated with the use of a system-based or traditional practice approach. Data for the evaluation were obtained from the case costing centre at a large teaching hospital in Ontario, supplemented by data from the literature. RESULTS: The per child cost for the system-based approach cohort was $176, compared with $173 in the traditional practice cohort. The higher cost associated with the system-based cohort reflects increased costs for predischarge screening and treatment and increased postdischarge follow-up visits. These costs are partially offset by reduced costs from fewer emergency room visits, hospital readmissions and kernicterus cases. Compared with the traditional approach, the cost to prevent one kernicterus case using the system-based approach was $570,496, the cost per life year gained was $26,279, and the cost per quality-adjusted life year gained was $65,698. CONCLUSION: The cost to prevent one kernicterus case using the system-based approach is much lower than previously reported in the literature. PMID:23277747

The adoption of disposable bioreactor technology as an alternate to traditional nondisposable technology is gaining momentum in the biotechnology industry. Evaluation of current disposable bioreactors systems to sustain high intensity fed-batch mammalian cell culture processes needs to be explored. In this study, an assessment was performed comparing single-use bioreactors (SUBs) systems of 50-, 250-, and 1,000-L operating scales with traditional stainless steel (SS) and glass vessels using four distinct mammalian cell culture processes. This comparison focuses on expansion and production stage performance. The SUB performance was evaluated based on three main areas: operability, process scalability, and process performance. The process performance and operability aspects were assessed over time and product quality performance was compared at the day of harvest. Expansion stage results showed disposable bioreactors mirror traditional bioreactors in terms of cellular growth and metabolism. Set-up and disposal times were dramatically reduced using the SUB systems when compared with traditional systems. Production stage runs for both Chinese hamster ovary and NS0 cell lines in the SUB system were able to model SS bioreactors runs at 100-, 200-, 2,000-, and 15,000-L scales. A single 1,000-L SUB run applying a high intensity fed-batch process was able to generate 7.5 kg of antibody with comparable product quality.

2006-01-01

Waste from traditional markets in Indonesia is the second largest stream of municipal solid waste after household waste. It has a higher organic fraction and may have greater potential to be managed on a business scale compared to household wastes. The attributed reason is that in general the wastes generated from traditional markets are more uniform, more concentrated and less hazardous than waste from other sources. This paper presents the results of environmental and economic assessments to compare the options available for traditional market waste disposal in Indonesia. The options compared were composting in labour intensive plants, composting in a centralised plant that utilised a simple wheel loader, centralised biogas production and landfill for electricity production. The current open dumping practice was included as the baseline case. A life cycle assessment (LCA) was used for environmental analysis. All options compared have lower environmental impacts than the current practice of open dumping. The biogas production option has the lowest environmental impacts. A cost-benefit analysis, which considered greenhouse gas savings, was used for the economic assessment. It was found that composting at a centralised plant is the most economically feasible option under the present Indonesian conditions. The approach reported in this study could be applied for 'a pre-feasibility first cut comparison' that includes environmental aspects in a decision-making framework for developing countries even though European emission factors were used.

This study is designed to address the need for evidence-based HIV/STI prevention approaches for drug-involved women under criminal justice community supervision. We tested the efficacy of a group-based traditional and multimedia HIV/STI prevention intervention (Project WORTH: Women on the Road to Health) among drug-involved women under community supervision. We randomized 306 women recruited from community supervision settings to receive either: (1) a four-session traditional group-based HIV/STI prevention intervention (traditional WORTH); (2) a four-session multimedia group-based HIV/STI prevention intervention that covered the same content as traditional WORTH but was delivered in a computerized format; or (3) a four-session group-based Wellness Promotion intervention that served as an attention control condition. The study examined whether the traditional or multimedia WORTH intervention was more efficacious in reducing risks when compared to Wellness Promotion; and whether multimedia WORTH was more efficacious in reducing risks when compared to traditional WORTH. Primary outcomes were assessed over the 12-month post-intervention period and included the number of unprotected sex acts, the proportion of protected sex acts, and consistent condom use. At baseline, 77% of participants reported unprotected vaginal or anal sex (n = 237) and 63% (n = 194) had multiple sex partners. Women assigned to traditional or multimedia WORTH were significantly more likely than women assigned to the control condition to report an increase in the proportion of protected sex acts (β = 0.10; 95% CI = 0.02-0.18) and a decrease in the number of unprotected sex acts (IRR = 0.72; 95% CI = 0.57-0.90). The promising effects of traditional and multimedia WORTH on increasing condom use and high participation rates suggest that WORTH may be scaled up to redress the concentrated epidemics of HIV/STIs among drug-involved women in the criminal justice system.

The present study aimed at determining if the addition of spaced education to traditional face-to-face lectures increased the time students kept busy with the learning content of a theoretical radiological science course. The study comprised two groups of 21 third-year dental students. The students were randomly assigned to a "traditional group" and a "spaced education group". Both groups followed a traditional face-to-face course. The intervention in the spaced education group was performed in way that these students received e-mails with a delay of 14 days to each face-to-face lecture. These e-mails contained multiple choice questions on the learning content of the lectures. The students returned their answers to the questions also by e-mail. On return they received an additional e-mail that included the correct answers and additional explanatory material.All students of both groups documented the time they worked on the learning content of the different lectures before a multiple choice exam was held after the completion of the course. All students of both groups completed the TRIL questionnaire (Trierer Inventar zur Lehrevaluation) for the evaluation of courses at university after the completion of the course. The results for the time invested in the learning content and the results of the questionnaire for the two groups were compared using the Mann-Whitney-U test. The spaced education group spent significantly more time (216.2 ± 123.9 min) on keeping busy with the learning content compared to the traditional group (58.4 ± 94.8 min, p < .0005). The spaced education group rated the didactics of the course significantly better than the traditional group (p = .034). The students of the spaced education group also felt that their needs were fulfilled significantly better compared to the traditional group as far as communication with the teacher was concerned (p = .022). Adding spaced education to a face-to-face theoretical radiological science course activates students in a way that they spend significantly more time on keeping busy with the learning content.

Most of the solid waste generation sources come from housing activities. The types of house buildings located in the Palembang is a traditional building which made from wood construction and a permanent house which made from concrete construction. The aim of this study is to calculate the amount of waste generation and to study the community behavior in waste management. The research used an observation and questionnaires that took place in 3 location of the traditional housing and 3 location of the permanent housing with 20 respondents for each location. The results showed that the waste generation in the traditional housing was 1.51 liters/person/day and the permanent housing was 1.63 liters/person/day. The collecting system in traditional housing was taken by the garbage cart every 1 days, while in permanent housing was taken by motorcycle, pick-up car, or dump truck every 1 or 2 days. The questionnaire results showed that 96,67% of the traditional housing and 91,67% of the permanent housing disposed of the waste in a mix condition. Amount of 6,67 % from the traditional housing and 0% of permanent housing managed their waste into compost. Amount of 15 % from traditional housing and 3,33% of permanent housing sold their waste. Based on the results, it can be concluded that the permanent housing has the largest number of waste generation and the people in traditional housing had a tendency to manage the waste better than the permanent housing.

Beta vulgaris (family: Chenopodiacea) is now much used in the food industry as a rich source of sugar but it is much less considered in medicine. Beet has been used in traditional medicine for hundreds of years to treat a variety of diseases such as constipation, decreased libido, gut and joint pain and dandruff. This study introduced the benefits of Beta vulgaris by reviewing of Iranian traditional documents from 10th century until now and also compared modern phytotherapy of plant beet from the electronic data banks such as ISI, Pub Med and Scopus with findings that extracted from traditional literature. This plant is known in Iranian traditional medicine (ITM) as Selgh (Arabic) or Choghondar (Farsi) and its leaves are used to develop treatments. Results confirmed that the plant referred to as Selgh in traditional books is that the plant Beta vulgaris in contemporary studies. Treatments that have not been evaluated in modern phytotherapy but do appear in traditional treatments include fever, as well as psychological and psychiatric issues. This article tells the history of beet in ITM and can confirm use of plant Beta vulgaris in medicinal practice. The report can be applied for certification of plant Beta vulgaris for researchers and experts. The findings of this study can help the researchers in producing therapeutic products and new application.

Technology and its applications are the most happening things in the world. So, is it in the field of medical education. This study was an evaluation of whether the conventional methods can compete with the test of technology. A comparative study of traditional method of teaching osteology in human anatomy with an innovative visual aided method. The study was conducted on 94 students admitted to MBBS 2014 to 2015 batch of Travancore Medical College. The students were divided into two academically validated groups. They were taught using conventional and video demonstrational techniques in a systematic manner. Post evaluation tests were conducted. Analysis of the mark pattern revealed that the group taught using traditional method scored better when compared to the visual aided method. Feedback analysis showed that, the students were able to identify bony features better with clear visualisation and three dimensional view when taught using the video demonstration method. The students identified visual aided method as the more interesting one for learning which helped them in applying the knowledge gained. In most of the questions asked, the two methods of teaching were found to be comparable on the same scale. As the study ends, we discover that, no new technique can be substituted for time tested techniques of teaching and learning. The ideal method would be incorporating newer multimedia techniques into traditional classes.

Study objective Examine the relation between aspects of gender equality and population health based on the premise that sex differences in health are mainly caused by the gender system. Setting/participants All Swedish couples (98 240 people) who had their first child together in 1978. Design The exposure of gender equality is shown by the parents' division of income and occupational position (public sphere), and parental leave and temporary child care (domestic sphere). People were classified by these indicators during 1978–1980 into different categories; those on an equal footing with their partner and those who were traditionally or untraditionally unequal. Health is measured by the outcomes of death during 1981–2001 and sickness absence during 1986–2000. Data are obtained by linking individual information from various national sources. The statistical method used is multiple logistic regressions with odds ratios as estimates of relative risks. Main results From the public sphere is shown that traditionally unequal women have decreased health risks compared with equal women, while traditionally unequal men tend to have increased health risks compared with equal men. From the domestic sphere is indicated that both women and men run higher risks of death and sickness when being traditionally unequal compared with equal. Conclusions Understanding the relation between gender equality and health, which was found to depend on sex, life sphere, and inequality type, seems to require a combination of the hypotheses of convergence, stress and expansion.

Field-portable detectors have been frequently used in routine monitoring and hazard assessment studies. However, there have been few thorough attempts to evaluate their potential as an alternative to the traditional procedure of collecting samples and analysing them in the laboratory. Thus, in this study the two approaches were compared in terms of their utility for monitoring (137)Cs activity in the Nyänget catchment in northern Sweden. The objectives were: (i) to determine the (137)Cs activity in soils associated with three types of vegetation, (ii) to map the geographical distribution of (137)Cs using the portable NaI detector connected to a GPS system (GDM-40), (iii) to identify (137)Cs anomalies in the catchment, and (iv) to compare the measurements obtained with the NaI detector and traditional sampling followed by laboratory analysis. Our results demonstrate that the GDM-40 has very good potential for making (137)Cs inventories and for detecting (137)Cs anomalies within large areas. The GDM-40 measurements identified differences between different hydrological areas that were not determined with the soil sampling method. The GDM-40 method is much faster than a traditional soil sampling method. However, soil sampling cannot be totally excluded because it is needed to calibrate the GDM-40. The agreement between the (137)Cs activity values obtained by the two approaches was 20% which is good in the field where so many factors vary.

Recruiting adolescent participants for research is challenging. The purpose of this study was to compare traditional in-person recruitment methods to social media recruitment. We recruited adolescents aged 14-18 years for a pilot physical activity intervention study, including a wearable physical activity tracking device and a Facebook group. Participants were recruited (a) in person from a local high school and an adolescent medicine clinic and (b) through social media, including Facebook targeted ads, sponsored tweets on Twitter, and a blog post. Data collected included total exposure (i.e., reach), engagement (i.e., interaction), and effectiveness. Effectiveness included screening and enrollment for each recruitment method, as well as time and resources spent on each recruitment method. In-person recruitment reached a total of 297 potential participants of which 37 enrolled in the study. Social media recruitment reached a total of 34,272 potential participants of which 8 enrolled in the study. Social media recruitment methods utilized an average of 1.6 hours of staff time and cost an average of $40.99 per participant enrolled, while in-person recruitment methods utilized an average of 0.75 hours of staff time and cost an average of $19.09 per participant enrolled. Social media recruitment reached more potential participants, but the cost per participant enrolled was higher compared to traditional methods. Studies need to consider benefits and downsides of traditional and social media recruitment methods based on study goals and population.

Distance education: The Introduction to College Chemistry course

NASA Astrophysics Data System (ADS)

Rice, Lisa A.

The purpose of this study was to compare a group of students in a traditional introductory college chemistry course to their distance learning counterparts. Both of the groups were required to have videotaped lessons and workbooks, but the traditional group met for two and one half hours each week with the instructor, whereas the distance students were not obligated to attend classroom meetings. The same instructor taught both of the groups and both were given equal access opportunities to the instructor beyond class meetings. The literature review included in this study indicated that distance learning has changed from a less popular alternative method for study to the forefront in modern academic institutions. The two target populations for this study were students enrolled in the Edison Community College Introduction to College Chemistry videotaped course and students taking the same course in a traditional setting. The study was conducted over a two consecutive semester interval, from August 2002 through May 2003. These two groups were compared on a number of items including gender, student attitudes about their own learning style, ethnicity, and final course grade. Information regarding attrition and reasons for choosing to take the course was collected. The results of this study found a significant difference in the number of students who withdrew from each course, with the distance students having the greater attrition rate. Gender and ethnicity were not significant in terms of student success when comparing the two groups. The self-reported behavior types showed no significant correlation to success for either the traditional or the distance students. However, many of the distance students felt that meeting occasionally for a face-to-face laboratory course would have been beneficial. Suggested applications of this study include strategies for a more successful distance learning experience for students. Also, laboratory courses such as chemistry have some inherent concerns that institutions must consider before offering such a course in a distance modality.

Ayurvedic preparations contain toxic elements like heavy metals and other chemicals exceeding their permissible limits. Ayurvedic method of detoxification of such products involves Shodhana. Hence, in present paper it has been decided to replace Ayurvedic Shodhana process by chemical purification method and to study the benefits and/or drawbacks of the traditional Ayurvedic Shodhana process. Crude aconite root, Ayurvedic Shodhana treated aconite root and chemical Shodhana treated aconite root samples were evaluated for toxicity and changes by animal studies and thin layer chromatography (TLC) respectively. The results of the toxicity study suggest that the modified method of Shodhana is less efficient as compared to the traditional Ayurvedic Shodhana process. TLC studies have shown that pseudoaconitine and aconitine were converted into far less toxic substances like veratroyl pseudoaconine and benzoylaconine respectively only in traditional Ayurvedic Shodhana.

Participation of adult cancer patients in US based clinical trials has remained near 3% for decades. Traditional research methodology reaches a small fraction of the target population with a fixed number of predetermined sites. Solutions are needed to ethically increase patient participation and accelerate cancer trial completion. We compared enrollment outcomes of traditional and patient focused research methodologies. A patient prioritized method (Just-In-Time, JIT) was implemented in parallel with traditionally managed sites in three cancer trials. JIT research sites were initiated after candidate patients presented, while traditional sites were initiated in advance. JIT sites enrolled with mean rates no less than, and up to 2.75 fold greater than, traditional sites. Mean patients enrolled per site was comparable (JIT-1.82, traditional-1.78). There were fewer non-enrolling JIT sites (2/28, 7%) compared to traditional sites 19/52, 37%). This retrospective analysis supports JIT as a prospective solution to increase cancer clinical trial enrollment and the efficiency of clinical trial administrative activities. PMID:23990689

Medical students’ attitudes and perspectives regarding novel computer-based practical spot tests compared to traditional practical spot tests

2013-01-01

Background Most universities currently practice traditional practical spot tests to evaluate students. However, traditional methods have several disadvantages. Computer-based examination techniques are becoming more popular among medical educators worldwide. Therefore incorporating the computer interface in practical spot testing is a novel concept that may minimize the shortcomings of traditional methods. Assessing students’ attitudes and perspectives is vital in understanding how students perceive the novel method. Methods One hundred and sixty medical students were randomly allocated to either a computer-based spot test (n=80) or a traditional spot test (n=80). The students rated their attitudes and perspectives regarding the spot test method soon after the test. The results were described comparatively. Results Students had higher positive attitudes towards the computer-based practical spot test compared to the traditional spot test. Their recommendations to introduce the novel practical spot test method for future exams and to other universities were statistically significantly higher. Conclusions The computer-based practical spot test is viewed as more acceptable to students than the traditional spot test. PMID:26451213

The pharmacologic activity of compounds isolated from Physalis peruviana has been demonstrated. The use of this fruit juice for treating pterygium has been reported in Colombian traditional medicine. However, studies demonstrating the fruit juice's pharmacologic activity when used in this disease have not been published to date. In the present study the anti-inflammatory and cytostatic activities of P. peruviana fruit juice in a rabbit eye inflammatory model were investigated. A novel rabbit eye inflammation model was developed for studying the juice's anti-inflammatory activity (based on an adaptation of the Draize test). Cytostatic activity was evaluated by measuring and comparing growth rates of cultured fibroblasts exposed and not exposed to various fruit juice concentrations. P. peruviana fruit juice exhibited a mild anti-inflammatory activity compared with methylprednisolone, a known anti-inflammatory drug. An interesting dose-dependent cytostatic effect on cultured fibroblasts was also established. The data found suggest that the P. peruviana fruit juice anti-pterygium effect described in traditional medicine may be related to its inhibiting fibroblast growth. The present study contributes to the pharmacologic knowledge regarding a remedy commonly used in Colombian traditional medicine.

This study was designed to determine if three-dimensional (3D) laser scanning techniques could be used to collect accurate anthropometric measurements, compared with traditional methods. The use of an alternative 3D method would allow for quick collection of data that could be used to change the parameters used for facepiece design, improving fit and protection for a wider variety of faces. In our study, 10 facial dimensions were collected using both the traditional calipers and tape method and a Konica-Minolta Vivid9i laser scanner. Scans were combined using RapidForm XOR software to create a single complete facial geometry of the subject as a triangulated surface with an associated texture image from which to obtain measurements. A paired t-test was performed on subject means in each measurement by method. Nine subjects were used in this study: five males (one African-American and four Caucasian females) and four females displaying a range of facial dimensions. Five measurements showed significant differences (p<0.05), with most accounted for by subject movements or amended by scanning technique modifications. Laser scanning measurements showed high precision and accuracy when compared with traditional methods. Significant differences found can be very small changes in measurements and are unlikely to present a practical difference. The laser scanning technique demonstrated reliable and quick anthropometric data collection for use in future projects in redesigning respirators.

Who applies and who gets admitted to UK graduate entry medicine? - an analysis of UK admission statistics

2011-01-01

Background Graduate-entry medicine is a recent development in the UK, intended to expand and broaden access to medical training. After eight years, it is time to evaluate its success in recruitment. Objectives This study aimed to compare the applications and admissions profiles of graduate-entry programmes in the UK to traditional 5 and 6-year courses. Methods Aggregate data on applications and admissions were obtained from the Universities and Colleges Admission Service covering 2003 to 2009. Data were extracted, grouped as appropriate and analysed with the Statistical Package for the Social Sciences. Results Graduate-entry attracts 10,000 applications a year. Women form the majority of applicants and admissions to graduate-entry and traditional medicine programmes. Graduate-entry age profile is older, typically 20's or 30's compared to 18 or 19 years in traditional programmes. Graduate-entry applications and admissions were higher from white and black UK ethnic communities than traditional programmes, and lower from southern and Chinese Asian groups. Graduate-entry has few applications or admissions from Scotland or Northern Ireland. Secondary educational achievement is poorer amongst graduate-entry applicants and admissions than traditional programmes. Conclusions Graduate-entry has succeeded in recruiting substantial additional numbers of older applicants to medicine, in which white and black groups are better represented and Asian groups more poorly represented than in traditional undergraduate programmes.

To study the clinical value of the colour-M-mode slope of the early diastolic left ventricular filling phase (Vp) and the early diastolic downward M-mode slope of the left atrioventricular plane displacement (EDS), compared with diastolic function assessed by traditional Doppler evaluation. In 65 consecutive patients EDS and Vp were compared with a four-degree traditional diastolic function classification, based on pulsed Doppler assessment of the early to atrial transmitral flow ratio (E/A), the E-wave deceleration time (Edt), and the systolic to diastolic (S/D) pulmonary venous inflow ratio. Vp (P=0.006) and EDS (P=0.045) were related to traditional diastolic function (Kruskal--Wallis analysis). EDS showed a trend brake between the moderate and severe diastolic dysfunction groups by traditional Doppler evaluation. Vp and EDS correlated weakly in simple linear regression analysis (r=0.33). Vp and EDS discriminated poorly between normal and highly abnormal diastolic function. Vp and EDS were significantly related to diastolic function by traditional Doppler evaluation. They were, however, not useful as single parameters of left ventricular diastolic function due to a small difference between normal and highly abnormal values, allowing for little between-measurement variability. Consequently, these methods for the evaluation of left ventricular diastolic function do not add significantly to traditional Doppler evaluation.

To compare collaborative and traditional childbirth care models. Cross-sectional study with 655 primiparous women in four public health system hospitals in Belo Horizonte, MG, Southeastern Brazil, in 2011 (333 women for the collaborative model and 322 for the traditional model, including those with induced or premature labor). Data were collected using interviews and medical records. The Chi-square test was used to compare the outcomes and multivariate logistic regression to determine the association between the model and the interventions used. Paid work and schooling showed significant differences in distribution between the models. Oxytocin (50.2% collaborative model and 65.5% traditional model; p < 0.001), amniotomy (54.3% collaborative model and 65.9% traditional model; p = 0.012) and episiotomy (collaborative model 16.1% and traditional model 85.2%; p < 0.001) were less used in the collaborative model with increased application of non-pharmacological pain relief (85.0% collaborative model and 78.9% traditional model; p = 0.042). The association between the collaborative model and the reduction in the use of oxytocin, artificial rupture of membranes and episiotomy remained after adjustment for confounding. The care model was not associated with complications in newborns or mothers neither with the use of spinal or epidural analgesia. The results suggest that collaborative model may reduce interventions performed in labor care with similar perinatal outcomes.

As traditional overnight on-call was shown to contribute to fatigue, Singapore moved to implement a shift system in 2014. We aimed to compare activity levels, sleep (using a wrist actigraph), fatigue and professional quality-of-life between residents working on night-float and those working on traditional overnight on-call. All postgraduate year 1 (PGY1) residents at our institution were invited to participate. Participants were required to wear a wrist actigraph for four months, and complete two validated surveys (Epworth Sleepiness Scale [ESS] and Professional Quality of Life Scale [ProQOL]) once each at the start and at the end of study. 49 residents were recruited. Residents on night-float and on-call showed comparable median (range) number of steps (10,061 [1,195-15,923] vs. 10,649 [308-21,910]; p = 0.429), amount of sleep logged (361 [149-630] minutes vs. 380 [175-484] minutes; p = 0.369) and time taken to fall asleep (6 [0-14] minutes vs. 6 [range 0-45] minutes; p = 0.726) respectively. Residents on night-float had less efficient sleep, with 90.5% participants having over 85% sleep efficiency compared to 100% of residents on on-call (p = 0.127). More residents on night-float reported ESS > 10 (73.8% vs. 38.5%) and higher burnout scores on ProQOL (41.4% vs. 21.4%) at the start of the study. However, this was similar to the end of the study and was not statistically significant. The physical activity and amount of sleep of residents on night-float and on-call rota were not significantly different. Residents on night-float reported comparatively higher fatigue and burnout.

The dean of the nursing college has an initiative to reform the BSN program in the college to minimize the use of lecturing and maximize interactive and lifelong learning. Appropriate assessment of how our students are prepared to be self-directed learners is crucial. To compare traditional and bridging students in regard to their SDLR scores in the nursing college in Saudi Arabia. This was a comparative study to compare traditional and bridging students in regard to their self-directed learning readiness scores (SDLR). The data was collected at the Nursing College, King Saud University, Riyadh, Saudi Arabia. A convenient sample of undergraduate nursing students at the sixth and eighth levels in both regular and bridging programs were recruited in this study to indicate their SDLR scores. The study used Fisher et al.'s (2001) Self-Directed Learning Readiness Scale to measure the self-directed learning readiness among undergraduate nursing students. The total mean score of SDLR was 144 out of 200, which indicated a low level of readiness for SDL. There were significant variations between the included academic levels among participants. Students in the sixth academic level scored higher in the total SDLR scores compared to eighth-level students. There were no significant variations with gender and program types in the total SDLR scores. A comprehensive plan is needed to prepare both faculty members and students to improve the SDL skills.

The objective of this study is to compare the effectiveness of a "cartoon-style" handout with a "traditional-style" handout in a self-study assignment for preclinical medical students. Third-year medical students (n = 93) at the Faculty of Medicine Ramathibodi Hospital, Mahidol University, took a pre-learning assessment of their knowledge of intercostal chest drainage. They were then randomly allocated to receive either a "cartoon-style" or a "traditional-style" handout on the same topic. After studying these over a 2-week period, students completed a post-learning assessment and estimated their levels of reading completion. Of the 79 participants completing the post-learning test, those in the cartoon-style group achieved a score 13.8% higher than the traditional-style group (p = 0.018). A higher proportion of students in the cartoon-style group reported reading ≥75% of the handout content (70.7% versus 42.1%). In post-hoc analyses, students whose cumulative grade point averages (GPA) from previous academic assessments were in the middle and lower range achieved higher scores with the cartoon-style handout than with the traditional one. In the lower-GPA group, the use of a cartoon-style handout was independently associated with a higher score. Students given a cartoon-style handout reported reading more of the material and achieved higher post-learning test scores than students given a traditional handout.

The application of nanotechnology in drinking water treatment and pollution cleanup is promising, as demonstrated by a number of field-based (pilot and full scale) and bench scale studies. A number of reviews exist for these nanotechnology-based applications; but to better illustrate its importance and guide its development, a direct comparison between traditional treatment technologies and emerging approaches using nanotechnology is needed. In this review, the performances of traditional technologies and nanotechnology for water treatment and environmental remediation were compared with the goal of providing an up-to-date reference on the state of treatment techniques for researchers, industry, and policy makers. Pollutants were categorized into broad classes, and the most cost-effective techniques (traditional and nanotechnology-based) in each category reported in the literature were compared. Where information was available, cost and environmental implications of both technologies were also compared. Traditional treatment technologies were found to currently offer the most cost-effective choices for removal of several common pollutants from drinking water and polluted sites. Nano-based techniques may however become important in complicated remediation conditions and meeting increasingly stringent water quality standards, especially in removal of emerging pollutants and low levels of contaminants. We also discuss challenges facing environmental application of nanotechnology were also discussed and potential solutions.

Educational computer games are examples of computer-assisted learning objects, representing an educational strategy of growing interest. Given the changes in the digital world over the last decades, students of the current generation expect technology to be used in advancing their learning requiring a need to change traditional passive learning methodologies to an active multisensory experimental learning methodology. The objective of this study was to compare a computer game-based learning method with a traditional learning method, regarding learning gains and knowledge retention, as means of teaching head and neck Anatomy and Physiology to Speech-Language and Hearing pathology undergraduate students. Students were randomized to participate to one of the learning methods and the data analyst was blinded to which method of learning the students had received. Students' prior knowledge (i.e. before undergoing the learning method), short-term knowledge retention and long-term knowledge retention (i.e. six months after undergoing the learning method) were assessed with a multiple choice questionnaire. Students' performance was compared considering the three moments of assessment for both for the mean total score and for separated mean scores for Anatomy questions and for Physiology questions. Students that received the game-based method performed better in the pos-test assessment only when considering the Anatomy questions section. Students that received the traditional lecture performed better in both post-test and long-term post-test when considering the Anatomy and Physiology questions. The game-based learning method is comparable to the traditional learning method in general and in short-term gains, while the traditional lecture still seems to be more effective to improve students' short and long-term knowledge retention.

To compare electrode array position, and depth of insertion of the Cochlear Hybrid-L24 electrode array following traditional cochleostomy and round window (RW) insertion. Prospective cadaveric temporal bone study. Ten cadaveric temporal bones were implanted with the Hybrid-L24 electrode array; half were introduced through a RW approach, whereas the other half were inserted through a traditional scala tympani cochleostomy. A micro-CT scanner was then used to evaluate electrode position, intracochlear trauma, and depth of insertion. All electrodes were inserted into the scala tympani without significant resistance. No electrodes demonstrated tip fold-over or through-fracturing of the osseous spiral lamina, basilar membrane, or spiral ligament. The average angular depth of insertion for all 10 electrodes was 252.4°. Compared to cochleostomy insertions, electrodes inserted through the RW more commonly acquired a proximal perimodiolar orientation, followed a more predictable course, and less commonly contacted critical soft tissue structures. The results of this study demonstrate that the Hybrid-L24 electrode can be successfully inserted using a RW or traditional cochleostomy technique with minimal intracochlear trauma. Our data also suggests that with this model, RW insertions may provide particular advantages with respect to hearing preservation over the traditional cochleostomy approach.

Considering the positive effects of certain nutrients on depression, increasingly prevalent in the contemporary societies, we investigated the nutritional content of prescribed and prohibited foodstuffs for depressed patients in Iranian Traditional Medicine resources. In order to conduct the study, credible sources of Iranian Traditional Medicine were primarily reviewed for the prescribed and prohibited foodstuffs for depressed patients. USDA database, as a well-known and valuable source, was then visited to determine the amount of effective nutrients in each foodstuff. Finally, the obtained amounts were compared with each other in three food groups, namely vegetables, fruits and nuts and also high protein products. In Iranian Traditional Medicine texts, the following are prescribed for depression management: basil, coriander, spinach, lettuce, squash, peppermint, dill, chicory, celery, chard, quince, cucumber, watermelon, grape, peach, pomegranate, banana, apple, currant, pistachio, dried fig, almond, egg, chicken, lamb, and trout; cabbage, eggplant, onion, garlic, broad beans, lentils, and beef, meanwhile, are prohibited. In this regard, the effective nutritional content of these foodstuffs was obtained and then compared in the three food groups. This study revealed that spinach, lettuce, chicory, and squash (vegetables), pomegranate and almond (fruits and nuts) and ultimately trout (high protein products) are the best effective foodstuffs on depressed patients from nutritional content aspect.

Dental students require a basic ability to explain and apply general principles of pathology to systemic, dental, and oral pathology. Although there have been recent advances in electronic and online resources, the academic effectiveness of using self-directed e-learning tools in pathology courses for dental students is unclear. The aim of this study was to determine if blended learning combining e-learning with traditional learning methods of lectures and tutorials would improve students' scores and satisfaction over those who experienced traditional learning alone. Two consecutive cohorts of Bachelor of Dentistry and Oral Health students taking the general pathology course at Griffith University in Australia were compared. The control cohort experienced traditional methods only, while members of the study cohort were also offered self-directed learning materials including online resources and online microscopy classes. Final assessments for the course were used to compare the differences in effectiveness of the intervention, and students' satisfaction with the teaching format was evaluated using questionnaires. On the final course assessments, students in the study cohort had significantly higher scores than students in the control cohort (p<0.01). Analysis of questionnaire results showed improved student satisfaction with the course in the study cohort. These findings suggest that the use of e-learning tools such as virtual microscopy and interactive online resources for delivering pathology instruction can be an effective supplement for developing dental students' competence, confidence, and satisfaction.

This study compares the traditional live lecture to a web-based approach in the teaching of bronchoscopy and evaluates the positive and negative aspects of both methods. We developed a web-based bronchoscopy curriculum, which integrates texts, images and animations. It was applied to first-year interns, who were later administered a multiple-choice test. Another group of eight first-year interns received the traditional teaching method and the same test. The two groups were compared using the Student's t-test. The mean scores (± SD) of students who used the website were 14.63 ± 1.41 (range 13-17). The test scores of the other group had the same range, with a mean score of 14.75 ± 1. The Student's t-test showed no difference between the test results. The common positive point noted was the presence of multimedia content. The web group cited as positive the ability to review the pages, and the other one the role of the teacher. Web-based bronchoscopy education showed results similar to the traditional live lecture in effectiveness.

In Mexico, six of every twenty Mexicans suffer psychiatric disorders at some time in their lives. This disease ranks fifth in the country. The objective was to determine and compare the cost-effectiveness of two models for hospital care (partial and traditional) at a psychiatric hospital of Instituto Mexicano del Seguro Social (IMSS). a multicenter study with a prospective cohort of 374 patients was performed. We made a cost-effectiveness analysis from an institutional viewpoint with a six-month follow-up. Direct medical costs were analyzed, with quality of life gains as outcome measurement. A decision tree and a probabilistic sensitivity analysis were used. patient care in the partial model had a cost 50 % lower than the traditional one, with similar results in quality of life. The cost per successful unit in partial hospitalization was 3359 Mexican pesos while in the traditional it increased to 5470 Mexican pesos. treating patients in the partial hospitalization model is a cost-effective alternative compared with the traditional model. Therefore, the IMSS should promote the infrastructure that delivers the psychiatric services to the patient attending to who requires it.

Effects of health-oriented descriptors on combustible cigarette and electronic cigarette packaging: an experiment among adult smokers in the United States.

Certain tobacco companies use health-oriented descriptors (eg, 100% organic) on product packaging and advertising of combustible cigarettes or electronic cigarettes (e-cigarettes) that create a 'health halo' around smoking and vaping. Previous observational research suggests that such language may be associated with more favourable attitudes and reduced risk perceptions toward these brands compared with others. This study aimed to determine the effects of health-oriented descriptors on smokers' attitude toward the brand, perception of packaging information, comparative harm versus other brands and intention to purchase either combustible cigarettes or e-cigarettes. US adult smokers were randomly assigned to view either a health-oriented language package ('100% organic,' 'all natural' or 'no additives'), traditional marketing language package ('fine quality,' 'premium blend' or '100% original') or a no-language package of a combustible cigarette brand (Study 1, n=405) or an e-cigarette brand (Study 2, n=396) in an experimental design. Study 1: Participants in the health-oriented condition reported more favourable perceptions toward the package information, lower comparative harm and higher intention to purchase combustible cigarettes versus the no language control. In addition, participants in the health-oriented condition reported more positive attitude toward the brand and lower comparative harm versus the traditional marketing condition. Study 2: Compared with the traditional marketing condition, participants in the health-oriented condition reported greater intention to purchase Absolute e-cigarettes. There were no significant differences in attitude toward the brand, perception of packaging information and comparative harm versus other brands across conditions. The effect of health-oriented language was significant for combustible cigarettesand e-cigarette packages. Policies to restrict health-oriented language on cigarette and e-cigarette packaging are recommended. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

2014-01-01

Pathways’ Housing First represents a radical departure from traditional programs that serve individuals experiencing homelessness and co-occurring psychiatric and substance use disorders. This paper considered two federally funded comparison studies of Pathways’ Housing First and traditional programs to examine whether differences were reflected in the perspectives of frontline providers. Both quantitative analysis of responses to structured questions with close-ended responses and qualitative analysis of open-ended responses to semistructured questions showed that Pathways providers had greater endorsement of consumer values, lesser endorsement of systems values, and greater tolerance for abnormal behavior that did not result in harm to others than their counterparts in traditional programs. Comparing provider perspectives also revealed an “implementation paradox”; traditional providers were inhibited from engaging consumers in treatment and services without housing, whereas HF providers could focus on issues other than securing housing. As programs increasingly adopt a Housing First approach, implementation challenges remain due to an existing workforce habituated to traditional services. PMID:24659925

Though traditional Korean medicine plays an important role in the Korean parallel health care system, there is limited information about the preference and usage of traditional Korean medicine compared to Western medicine because they have different disease classification systems. The aim of this study is to determine the relative preference for traditional Korean medicine using data acquired nationwide. Data from the 2008 Korea Health Panel were analyzed to determine the preference of medical services by disease. The use of traditional Korean medicine use is defined by the type of medical institution they used. Disease types, number of visits and out of pocket expenditures were analyzed. Traditional Korean medicine was used in only a small number of cases that were emergencies or hospitalization. However, in terms of outpatient services, traditional Korean medicine was used in 7.8% of all cases and represented 9.9% of total medical costs. Among disease groups, traditional Korean medicine use was higher in patients with nervous system and musculoskeletal system diseases. And patients with musculoskeletal and nervous system diseases such as arthrosis were the most likely to use traditional Korean medicine particularly in an outpatient setting. Korean characteristics of service use resemble the complementary and alternative medicine use in other countries in terms of disease group, and the complementary and alternative medicine should be considered to estimate the burden of disease in countries with parallel health care systems, such as Korea. This is the first study determined the actual preference of traditional Korean medicine for specific chronic diseases.

The feasibility and potential of using drones for providing flotation devices in cases of drowning have not yet been assessed. We hypothesize that a drone carrying an inflatable life buoy is a faster way to provide flotation compared with traditional methods. The purpose of this study is to explore the feasibility and efficiency of using a drone for delivering and providing flotation support to conscious simulated drowning victims. A simulation study was performed with a simulated drowning victim 100 m from the shore. A drone (DJI Phantom 4; dji, Shenzhen, China) equipped with an inflatable life buoy of 60 N was compared with traditional surf rescue swimming for providing flotation. The primary outcome was delay (minutes:seconds). A total number of 30 rescues were performed with a median time to delivery of the floating device of 30 seconds (interquartile range [IQR] = 24-32 seconds) for the drone compared with 65 seconds (IQR = 60-77 seconds) with traditional rescue swimming (P < .001). The drone had an accuracy of 100% in dropping the inflatable life buoy < 5 m from the victim, with a median of 1 m (IQR = 1-2 m). Using drones to deliver inflatable life buoys is safe and may be a faster method to provide early flotation devices to conscious drowning victims compared with rescue swimming.

There is a growing use of mobile devices to access the Internet. We examined whether participants who used a mobile device to access a brief online survey were quicker to respond to the survey but also, less likely to complete it than participants using a traditional web browser. Using data from a recently completed online intervention trial, we found that participants using mobile devices were quicker to access the survey but less likely to complete it compared to participants using a traditional web browser. More concerning, mobile device users were also less likely to respond to a request to complete a six week follow-up survey compared to those using traditional web browsers. With roughly a third of participants using mobile devices to answer an online survey in this study, the impact of mobile device usage on survey completion rates is a concern.

Moradi, Sara; Fazlali, Alireza; Hamedi, Hamid

Background: Hydro-distillation (HD) method is a traditional technique which is used in most industrial companies. Microwave-assisted Hydro-distillation (MAHD) is an advanced HD technique utilizing a microwave oven in the extraction process. Methods: In this research, MAHD of essential oils from the aerial parts (leaves) of rosemary (Rosmarinus officinalis L.) was studied and the results were compared with those of the conventional HD in terms of extraction time, extraction efficiency, chemical composition, quality of the essential oils and cost of the operation. Results: Microwave hydro-distillation was superior in terms of saving energy and extraction time (30 min, compared to 90 min in HD). Chromatography was used for quantity analysis of the essential oils composition. Quality of essential oil improved in MAHD method due to an increase of 17% in oxygenated compounds. Conclusion: Consequently, microwave hydro-distillation can be used as a substitute of traditional hydro-distillation. PMID:29296263

Nybo, Lars; May, Michael

2015-06-01

The present study was conducted to investigate the effects of changing a laboratory physiology course for undergraduate students from a traditional step-by-step guided structure to an inquiry-based approach. With this aim in mind, quantitative and qualitative evaluations of learning outcomes (individual subject-specific tests and group interviews) were performed for a laboratory course in cardiorespiratory exercise physiology that was conducted in one year with a traditional step-by-step guided manual (traditional course) and the next year completed with an inquiry-based structure (I-based course). The I-based course was a guided inquiry course where students had to design the experimental protocol and conduct their own study on the basis of certain predefined criteria (i.e., they should evaluate respiratory responses to submaximal and maximal exercise and provide indirect and direct measures of aerobic exercise capacity). The results indicated that the overall time spent on the experimental course as well as self-evaluated learning outcomes were similar across groups. However, students in the I-based course used more time in preparation (102 ± 5 min) than students in the traditional course (42 ± 3 min, P < 0.05), and 65 ± 5% students in the I-based course searched for additional literature before experimentation compared with only 2 ± 1% students in the traditional course. Furthermore, students in the I-based course achieved a higher (P < 0.05) average score on the quantitative test (45 ± 3%) compared with students in the traditional course (31 ± 4%). Although students were unfamiliar with cardiorespiratory exercise physiology and the experimental methods before the course, it appears that an inquiry-based approach rather than one that provides students with step-by-step instructions may benefit learning outcomes in a laboratory physiology course.

Green roofs and cool roofs are alternative roofing strategies that mitigate urban heat island effects and improve building energy performance. Green roofs consist of soil and vegetation layers that provide runoff reduction, thermal insulation, and potential natural habitat, but can require regular maintenance. Cool roofs involve a reflective layer that reflects more sunlight than traditional roofing materials, but require additional insulation during winter months. This study evaluates several roofing strategies in terms of energy performance, urban heat island mitigation, water consumption, and economic cost. We use MLCan, a multi-layer canopy model, to simulate irrigated and non-irrigated green roof cases with shallow and deep soil depths during the spring and early summer of 2012, a drought period in central Illinois. Due to the dry conditions studied, periodic irrigation is implemented in the model to evaluate its effect on evapotranspiration. We simulate traditional and cool roof scenarios by altering surface albedo and omitting vegetation and soil layers. We find that both green roofs and cool roofs significantly reduce surface temperature compared to the traditional roof simulation. Cool roof temperatures always remain below air temperature and, similar to traditional roofs, require low maintenance. Green roofs remain close to air temperature and also provide thermal insulation, runoff reduction, and carbon uptake, but might require irrigation during dry periods. Due to the longer lifetime of a green roof compared to cool and traditional roofs, we find that green roofs realize the highest long term cost savings under simulated conditions. However, using longer-life traditional roof materials (which have a higher upfront cost) can help decrease this price differential, making cool roofs the most affordable option due to the higher maintenance costs associated with green roofs

China, Japan, Korea, and Taiwan have developed modernized education systems in traditional medicine. This study aims to provide an overview of the education systems in these countries and compare them. Data were collected through the websites of government agencies, universities, and relevant organizations. These countries have systemically developed basic medical education (BME), postgraduate medical education (PGME), and continuing medical education (CME) in traditional medicine. BME is provided at colleges of traditional medicine at the undergraduate level and graduate levels. The length of education at the undergraduate level is five, six, and seven years in China, Korea, and Taiwan, respectively; the length at the graduate level is four years in Korea and five years in Taiwan. A seven- or eight-year program combining undergraduate and graduate courses is unique to China. In Japan, unlike in other countries, there are two distinct education systems-one is comprised of courses on traditional medicine included in the curriculum for Western medical doctors, and the other is a three- or four-year undergraduate program for practitioners including acupuncturists and moxibustionists. PGME in Korea consists of one-year internship and three-year residency programs which are optional; however, in China and Taiwan, internship is required for the national licensing examination and further training is in the process of standardization. The required credits for maintenance of CME are eight per year in Korea, 25 per year in China, and 180 over six years in Taiwan. The design of the educational systems in these countries can provide useful information for the development of education in traditional medicine around the world. Copyright © 2016.

This study of 598 7th grade students of Mexican origin examined the role of traditional cultural values as a mediator of the effects of immigrant status, Mexican cultural orientation and Anglo cultural orientation on adolescent externalizing behavior and academic engagement. Immigrant status of adolescents and their maternal caregivers uniquely predicted increased Mexican cultural orientation and decreased Anglo cultural orientation, and both Mexican and Anglo cultural orientation related positively to adolescents' endorsement of traditional cultural values. Endorsement of traditional cultural values related, in turn, to decreased externalizing behaviors and increased academic engagement and these findings were replicated across adolescent and teacher report of these two outcomes. Tests of mediation provided further evidence to support these pathways. Findings support the central importance of traditional cultural values as a protective resource that explains why immigrant youth exhibit fewer externalizing problems and increased academic engagement when compared to their second and third generation peers.

Coronary artery disease (CAD) is multifactorial disease, in which thrombotic occlusion and calcification occur usually. New strategies have been made for diagnosis and treatment of CAD, such as transradial catheterization. Hemostasis could be done in two approaches: traditional and patent. Our aim is to find the best approach with lowest complication. In a comparative study, 120 patients were recruited and divided randomly into two subgroups, including traditional group (60 patients; 24 females, 36 males; mean age: 64.35 ± 10.56 years) and patent group (60 patients; 28 females, 32 males; mean age: 60.15 ± 8.92 years). All demographic data including age, gender, body mass index, and CAD-related risk factors (smoking, diabetes, hypertension) and technical data including the number of catheters, procedure duration, and hemostatic compression time and clinical outcomes (radial artery occlusion [RAO], hematoma, bleeding) were collected. Data were analyzed by SPSS version 16. Our findings revealed that the incidence of RAO was significantly lower in patent groups compared with traditional group ( P = 0.041). Furthermore, the difference incidence of RAO was higher in early occlusion compare with late one ( P = 0.041). Moreover, there were significant relationship between some factors in patients of traditional group with occlusion (gender [ P = 0.038], age [ P = 0.031], diabetes mellitus [ P = 0.043], hemostatic compression time [ P = 0.036]) as well as in patent group (age [ P = 0.009], hypertension [ P = 0.035]). Our findings showed that RAO, especially type early is significantly lower in patent method compared classic method; and patent hemostasis is the safest method and good alternative for classical method.

Traditional biomass has been the major source of cooking energy for major segment of Ethiopian population for thousands of years. Cognizant of this energy poverty, the Government of Ethiopia has been spending huge sum of money to increase hydroelectric power generating stations. To assess current levels and correlates of traditional cooking energy sources utilization. A community based cross-sectional study was conducted employing both quantitative and qualitative approaches on systematically selected 423 households for quantitative and purposively selected 20 people for qualitative parts. SPSS version 16 for windows was used to analyze the quantitative data. Logistic regression was fitted to assess possible associations and its strength was measured using odds ratio at 95% CI. Qualitative data were analyzed thematically. The study indicated that 95% of households still use traditional biomass for cooking. Those who were less knowledgeable about negative health and environmental effects of traditional cooking energy sources were seven and six times more likely to utilize them compared with those who were knowledgeable (AOR (95% CI) = 7.56 (1.635, 34.926), AOR (95% CI) = 6.68 (1.80, 24.385), resp.). The most outstanding finding of this study was that people use traditional energy for cooking mainly due to lack of the knowledge and their beliefs about food prepared using traditional energy. That means "...people still believe that food cooked with charcoal is believed to taste delicious than cooked with other means."  The majority of households use traditional biomass for cooking due to lack of knowledge and belief. Therefore, mechanisms should be designed to promote electric energy and to teach the public about health effects of traditional cooking energy source.

Digital and traditional slides for teaching cellular morphology: a comparative analysis of learning outcomes.

2012-01-01

Recent advances in technology have brought forth an intriguing new tool for teaching hematopoietic cellular identification skills: the digital slide. Although digitized slides offer a number of appealing options for educators, little research has been done to examine how their utilization would impact learning outcomes. To fill that void, this study was designed to examine student performance, skill retention and transferability, and self-efficacy beliefs amongst undergraduate MLS students learning cellular morphology with digital versus traditional slides. Results showed that students learning with digital slides performed better on assessments containing only traditional slide specimens than students learning with traditional slides, both immediately following the learning activity and after a considerable duration of time. Students learning with digital slides also reported slightly higher levels of self-efficacy related to cellular identification. The findings of this study suggest that students learning cellular identification skills with digital slides are able to transfer that skill directly to traditional slides, and that their ability to identify cells is not negatively affected in present or future settings.

Aim. To evaluate the pain experience and behavior during dental injection, using the Wand computerized delivery system versus conventional local anesthesia in children and adolescents. Methods. An observational crossover split mouth study was performed on 67 patients (aged 7 to 15 years), requiring local anesthesia for dental treatments in both sides of the dental arch. Patients received both types of injections in two separate appointments, one with the use of a Computer Delivery System (the Wand STA system) and one with the traditional syringe. The following data were recorded: pain rating; changes in heart rate; level of collaboration; patient satisfaction. The data were analyzed using ANOVA for quantitative outcomes and nonparametric analysis (Kruskal-Wallis) for qualitative parameters. Results. The use of the Wand system determined significantly lower pain ratings and lower increase of heart rate than the traditional syringe. During injection, the number of patients showing a relaxed behavior was higher with the Wand than with the traditional local anesthesia. The patient level of satisfaction was higher with the Wand compared to the conventional local anesthesia. Conclusions. The Wand system may provide a less painful injection when compared to the conventional local anesthesia and it seemed to be better tolerated with respect to a traditional syringe.

Cyberbullying: a storm in a teacup?

Cyberbullying has been portrayed as a rising 'epidemic' amongst children and adolescents. But does it create many new victims beyond those already bullied with traditional means (physical, relational)? Our aim was to determine whether cyberbullying creates uniquely new victims, and whether it has similar impact upon psychological and behavioral outcomes for adolescents, beyond those experienced by traditional victims. This study assessed 2745 pupils, aged 11-16, from UK secondary schools. Pupils completed an electronic survey that measured bullying involvement, self-esteem and behavioral problems. Twenty-nine percent reported being bullied but only 1% of adolescents were pure cyber-victims (i.e., not also bullied traditionally). Compared to direct or relational victims, cyber-victimization had similar negative effects on behavior (z = -0.41) and self-esteem (z = -0.22) compared to those not involved in bullying. However, those bullied by multiple means (poly-victims) had the most difficulties with behavior (z = -0.94) and lowest self-esteem (z = -0.78). Cyberbullying creates few new victims, but is mainly a new tool to harm victims already bullied by traditional means. Cyberbullying extends the reach of bullying beyond the school gate. Intervention strategies against cyberbullying may need to include approaches against traditional bullying and its root causes to be successful.

During injection, the number of patients showing a relaxed behavior was higher with the Wand than with the traditional local anesthesia. The patient level of satisfaction was higher with the Wand compared to the conventional local anesthesia. Conclusions. The Wand system may provide a less painful injection when compared to the conventional local anesthesia and it seemed to be better tolerated with respect to a traditional syringe. PMID:28293129

The Dunfermline Eastern Expansion (DEX) is a 350 ha mixed development which commenced in 1996. Downstream water quality and flooding issues necessitated a holistic approach to drainage planning and the site has become a European showcase for the application of Sustainable Urban Drainage Systems (SUDS). However, there is minimal data available regarding the real costs of operating and maintaining SUDS to ensure they continue to perform as per their design function. This remains one of the primary barriers to the uptake and adoption of SUDS. This paper reports on what is understood to be the only study in the UK where actual costs of constructing and maintaining SUDS have been compared to an equivalent traditional drainage solution. To compare SUDS costs with traditional drainage, capital and maintenance costs of underground storage chambers of analogous storage volumes were estimated. A whole life costing methodology was then applied to data gathered. The main objective was to produce a reliable and robust cost comparison between SUDS and traditional drainage. The cost analysis is supportive of SUDS and indicates that well designed and maintained SUDS are more cost effective to construct, and cost less to maintain than traditional drainage solutions which are unable to meet the environmental requirements of current legislation.

Fluoroscopy-based frameless stereotactic systems provide feedback to the surgeon using virtual fluoroscopic images. The real-life accuracy of these virtual images has not been compared with traditional fluoroscopy in a clinical setting. We prospectively studied 23 consecutive cases. In two cases, registration errors precluded the use of virtual fluoroscopy. Pedicle probes placed with virtual fluoroscopic imaging were imaged with traditional fluoroscopy in the remaining 21 cases. Position of the probes was judged to be ideal, acceptable but not ideal, or not acceptable based on the traditional fluoroscopic images. Virtual fluoroscopy was used to place probes in for 97 pedicles from L1 to the sacrum. Eighty-eight probes were judged to be in ideal position, eight were judged to be acceptable but not ideal, and one probe was judged to be in an unacceptable position. This probe was angled toward an adjacent disc space. Therefore, 96 of 97 probes placed using virtual fluoroscopy were found to be in an acceptable position. The positive predictive value for acceptable screw placement with virtual fluoroscopy compared with traditional fluoroscopy was 99%. A probe placed with virtual fluoroscopic guidance will be judged to be in an acceptable position when imaged with traditional fluoroscopy 99% of the time.

Conservation of the evolutionary diversity among organisms should be included in the selection of priority regions for preservation of Earth's biodiversity. Traditionally, biodiversity has been determined from an assessment of species richness (S), abundance, evenness, rarity, etc. of organisms but not from variation in species' evolutionary histories. Phylogenetic diversity (PD) measures evolutionary differences between taxa in a community and is gaining acceptance as a biodiversity assessment tool. However, with the increase in the number of ways to calculate PD, end-users and decision-makers are left wondering how metrics compare and what data are needed to calculate various metrics. In this study, we used massively parallel sequencing to generate over 65,000 DNA characters from three cellular compartments for over 60 species in the asterid clade of flowering plants. We estimated asterid phylogenies from character datasets of varying nucleotide quantities, and then assessed the effect of varying character datasets on resulting PD metric values. We also compared multiple PD metrics with traditional diversity indices (including S) among two endangered grassland prairies in Nebraska (U.S.A.). Our results revealed that PD metrics varied based on the quantity of genes used to infer the phylogenies; therefore, when comparing PD metrics between sites, it is vital to use comparable datasets. Additionally, various PD metrics and traditional diversity indices characterize biodiversity differently and should be chosen depending on the research question. Our study provides empirical results that reveal the value of measuring PD when considering sites for conservation, and it highlights the usefulness of using PD metrics in combination with other diversity indices when studying community assembly and ecosystem functioning. Ours is just one example of the types of investigations that need to be conducted across the tree of life and across varying ecosystems in order to build a database of phylogenetic diversity assessments that lead to a pool of results upon which a guide through the plethora of PD metrics may be prepared for use by ecologists and conservation planners.

Therapy for moderate to severe acute food protein-induced enterocolitis syndrome (FPIES) typically consists of intravenous fluids and corticosteroids (traditional therapy). Ondansetron has been suggested as an adjunctive treatment. We aimed to evaluate the efficacy of the parenteral (intravenous or intramuscular) ondansetron vs traditional therapy to resolve the symptoms of acute FPIES. Cases of FPIES who had a positive oral food challenge (OFC) were retrospectively examined at two major hospitals over a two-year period (Rome, Italy; and Sydney, Australia). The efficacy of therapy, based on the percentage of cases who stopped vomiting, was compared in cases who received parenteral ondansetron and in cases who received traditional therapy or no pharmacological therapy. A total of 66 patients were included: 37 had parenteral ondansetron, 14 were treated with traditional therapy, and 15 did not receive any pharmacological therapy. Nineteen percentage of children treated with ondansetron continued vomiting after the administration of the therapy vs 93% of children who received traditional therapy (P < 0.05, relative risk = 0.2). Children who received ondansetron or no therapy were less likely to require an admission overnight compared with those who received traditional therapy (P < 0.05). Parenteral ondansetron is significantly more effective than traditional therapy in resolving acute symptoms of FPIES. The relative risk = 0.2 greatly reduces the bias linked to the lack of randomization. These findings suggest an effective treatment for vomiting in positive FPIES OFCs and allow for more confidence in performing OFCs. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Waste from traditional markets in Indonesia is the second largest stream of municipal solid waste after household waste. It has a higher organic fraction and may have greater potential to be managed on a business scale compared to household wastes. The attributed reason is that in general the wastes generated from traditional markets are more uniform, more concentrated and less hazardous than waste from other sources. This paper presents the results of environmental and economic assessments to compare the options available for traditional market waste disposal in Indonesia. The options compared were composting in labour intensive plants, composting in amore » centralised plant that utilised a simple wheel loader, centralised biogas production and landfill for electricity production. The current open dumping practice was included as the baseline case. A life cycle assessment (LCA) was used for environmental analysis. All options compared have lower environmental impacts than the current practice of open dumping. The biogas production option has the lowest environmental impacts. A cost-benefit analysis, which considered greenhouse gas savings, was used for the economic assessment. It was found that composting at a centralised plant is the most economically feasible option under the present Indonesian conditions. The approach reported in this study could be applied for 'a pre-feasibility first cut comparison' that includes environmental aspects in a decision-making framework for developing countries even though European emission factors were used.« less

Fast-track surgery after gynaecological oncological surgery: study protocol for a prospective randomised controlled trial.

PubMed

Cui, Ling; Shi, Yu; Zhang, G N

2016-12-15

Fast-track surgery (FTS), also known as enhanced recovery after surgery, is a multidisciplinary approach to accelerate recovery, reduce complications, minimise hospital stay without increasing readmission rates, and reduce health care costs, all without compromising patient safety. The advantages of FTS in abdominal surgery most likely extend to gynaecological surgery, but this is an assumption, as FTS in elective gynaecological surgery has not been well studied. No consensus guidelines have been developed for gynaecological oncological surgery although surgeons have attempted to introduce slightly modified FTS programmes for patients undergoing such surgery. To our knowledge, there are no published randomised controlled trials; however, some studies have shown that FTS in gynaecological oncological surgery leads to early hospital discharge with high levels of patient satisfaction. The aim of this study is whether FTS reduces the length of stay in hospital compared to traditional management. The secondary aim is whether FTS is associated with any increase in post-surgical complications compared to traditional management (for both open and laparoscopic surgery). This trial will prospectively compare FTS and traditional management protocols. The primary endpoint is the length of post-operative hospitalisation (days, mean ± standard deviation), defined as the number of days between the date of discharge and the date of surgery. The secondary endpoints are complications in both groups (FTS versus traditional protocol) occurring during the first 3 months post-operatively including infection (wound infection, lung infection, intraperitoneal infection), post-operative nausea and vomiting, ileus, post-operative haemorrhage, post-operative thrombosis, and the Acute Physiology and Chronic Health Enquiry II score. The advantages of FTS most likely extend to gynaecology, although, to our knowledge, there are no randomised controlled trials. The aim of this study is to compare the post-operative length of hospitalisation after major gynaecological or gynaecological oncological surgery and to analyse patients' post-operative complications. This trial may reveal whether FTS leads to early hospital discharge with few complications after gynaecological surgery. NCT02687412 . Approval Number: SCCHEC20160001.

The aim of this study was to document the types of diseases treated by the use of medicinal plants, their main applications and also to have a report of the major diseases treated at the Hospital of San Pablo de Huacareta (Chuquisaca Bolivia). We conducted semi-structured interviews on the use medicinal plants with 10 local informants, and categorized the kinds of diseases treated by traditional medicine. We obtained reports of cases treated at the Hospital of Huacareta in order to compare the use frequency of traditional medicine and allopathic medicine for the treatment of recurrent diseases in the area. Our survey identified 258 traditional medicine uses, spanning a total of 13 diseases categories and including 91 native and exotic plant species and one unidentified sample plant type. Gastrointestinal disorders (55%) were most frequently treated with medicinal plants, followed by afflictions of the musculoskeletal system (25%) and dermatological disorders (24%). Hospital information indicates that the most common diseases are acute respiratory infections (47%) and acute diarrheal diseases (37%). The herbal remedies were mostly used in the form of teas and decoctions. The informants used mainly native plant species, although exotic species has been introduced to the pharmacopoeia. The treatment of gastrointestinal disorders is the primary objective of the medical ethnobotany of the inhabitants of Huacareta, while respiratory system diseases are mostly treated in the hospital. Looking at the data from the Hospital records we can infer that gastrointestinal disorders are among the most common diseases in the study area. For most respondents, traditional medicine is a reliable choice for the care of their illnesses. However, the preference of the population for either traditional medicine or allopathic medicine needs to be clarified in future comparative studies to obtain more convincing results. The results presented can be used as a base for subsequent work related to traditional medicine and its contribution to allopathic medicine in San Pablo de Huacareta.

This analytical cross-sectional study examined the nutrient intakes, dietary compliance, dietary supplementation and traditional remedy usage in type 2 diabetes mellitus (T2DM) patients from selected tertiary hospitals in multi-racial Malaysia. We compared the different characteristics of T2DM patients with and without cardiovascular disease (CVD). Socio-demographic status, dietary intakes, dietary supplementation, traditional remedy use, medical history, anthropometric measurements and clinical characteristics were obtained from face-to-face interviews. A total of 313 patients who were treated for T2DM participated in this study, in which 36.1% of them had CVD. The mean age of study subjects was 55.7 ± 9.2 years; mean diabetes duration was 10.1 ± 8.1 years; 52.1% were females; and 47.0% were Malays. The mean total energy intake of the subjects was 1674 ± 694 kcal/day, and patients with CVD consumed higher total calories (p = 0.001). Likewise, the mean carbohydrate, protein and total fat intake of CVD patients were significantly higher than non-CVD patients (p < 0.05), while mean intakes of cholesterol, fibre, minerals and all vitamins were comparable between CVD and non-CVD patients. Regardless of CVD status, a notably high proportion of the subjects did not meet the recommendations of the Medical Nutrition Therapy Guidelines for Type 2 Diabetes for total energy, carbohydrate, protein, total fat, and fibre intakes. Meanwhile, 52.4% used at least one dietary supplement and 12.1% took single traditional remedy or in various combinations. Traditional remedies and supplement intake did not differ between CVD and non-CVD subjects. It is suggested that T2DM patients should be educated based on their personalized dietary intake, dietary supplementation and traditional remedy usage. The recommendations for T2DM patients shall be met to achieve the optimal metabolic goals and minimize the potential diabetic complications. PMID:25713789

Compliance by residents in pediatrics to pediatric resuscitation guidelines is low. In many French faculties, a 1-h traditional lecture is still used to educate medical students about pediatric cardiopulmonary arrest (CPA). We developed an innovative pedagogic course combining a 23-min video and 3-h simulation exercises to improve knowledge and skills of medical students. A prospective controlled study was conducted. Medical student knowledge was tested before, just after, and 6-12 months after the innovative course and compared to that of a cohort who attended the traditional lecture. A high-fidelity mannequin simulator simulating cardiopulmonary arrest was used to assess and compare the skills of the study and control groups. Costs of the courses were evaluated; 809 of 860 (94 %) medical students were assessed for knowledge. Six to 12 months after the courses, the median score was significantly higher for the innovative group than that for the traditional lecture group (p < 0.001). In terms of skills, student in the innovative group scored higher on the performance score than the control group (p < 0.01). The innovative course was 24 times more expensive. Combination of video and simulation allows better retention of knowledge than a traditional lecture and leads to better compliance to resuscitation guidelines. • Compliance by residents to pediatric resuscitation guidelines is low. • We developed an innovative pedagogic course combining an educational video and simulation. What is new: • Knowledge retention after the innovative course was better than after a traditional lecture. • Sixty-six students tested on their skills demonstrated better compliance to resuscitation guidelines.

Hydrologic time series forecasting is an essential task in water resources management and it becomes more difficult due to the complexity of runoff process. Traditional stochastic models such as ARIMA family has been used as a standard approach in time series modeling and forecasting of hydrological variables. Due to the nonlinearity in hydrologic time series data, machine learning approaches has been studied with the advantage of discovering relevant features in a nonlinear relation among variables. This study aims to compare the predictability between the traditional stochastic model and the machine learning approach. Seasonal ARIMA model was used as the traditional time series model, and Random Forest model which consists of decision tree and ensemble method using multiple predictor approach was applied as the machine learning approach. In the application, monthly inflow data from 1986 to 2015 of Chungju dam in South Korea were used for modeling and forecasting. In order to evaluate the performances of the used models, one step ahead and multi-step ahead forecasting was applied. Root mean squared error and mean absolute error of two models were compared.

The aim of this study was to compare new knotless single-row and double-row suture anchor techniques with traditional transosseous suture techniques for different sized rotator cuff tears in an animal model. The study included 56 cadaveric sheep shoulders. Supraspinatus cuff tears of 1 cm repaired with new knotless single-row suture anchor technique and supraspinatus and infraspinatus rotator cuff tears of 3 cm repaired with double-row suture anchor technique were compared to traditional transosseous suture techniques and control groups. The repaired tendons were loaded with 5 mm/min static velocity with 2.5 kgN load cell in Instron 8874 machine until the repair failure. The 1 cm transosseous group was statistically superior to 1 cm control group (p=0.021, p<0.05) and the 3 cm SpeedBridge group was statistically superior to the 1 cm SpeedFix group (p=0.012, p<0.05). The differences between the other groups were not statistically significant. No significant difference was found between the new knotless suture anchor techniques and traditional transosseous suture techniques.

The development of e-cigarettes was initially hailed as a resource in facilitating a reduction in or cessation of cigarette smoking. Many users of e-cigarettes are ‘dual users’, smoking traditional cigarettes and e-cigarettes. The present qualitative study examines the factors that a group of 20 dual users considered to have been influential in their decisions to use e-cigarettes and their comparative evaluations of e-cigarettes and traditional cigarettes. Health concerns were not found to be sole motivators. Participants pointed to financial and contextual considerations, particularly peer influence on uptake and continued usage of e-cigarettes. E-cigarettes were evaluated as comparable to cigarettes in some ways but not in other important respects such as sensation and satisfaction. Different social evaluations of cigarette and e-cigarette usage were discerned which influenced how participants identified as smokers, ‘vapers’ or neither. Findings are discussed in relation to social representations, identity and implications for continued e-cigarette usage among dual users. PMID:28680694

Although many higher education programs are using the Internet to teach classes, there are few published reports on the effectiveness of this method on test scores or student satisfaction. The purpose of this study was to compare test and student satisfaction scores of graduate nursing students who take a nursing research course via the Internet with those of students who take the same course via traditional lecture instruction. In addition, student technical support use and Internet student lecture attendance also were examined. A total of 97 students (Internet, 44; lectures, 53) participated. There were no significant differences in test scores and overall course student satisfaction (P > .05). However, the Internet students reported significantly higher (P = .04) stimulation of learning compared with the traditional lecture students. Technical support use by the Internet students was high initially and was related to software problems. Of interest were the large proportion of Internet students (73 percent) who attended at least 3 of the 10 lectures. Use of the Internet to teach graduate-level nursing research can provide comparable learning and student satisfaction to traditional lecture instructional methods.

To evaluate the clinical efficacy and cost-effectiveness of ultrasonic shears and the electrothermal bipolar vessel sealing system, in comparison to the traditional cold knife and bipolar forceps, in oral and oropharyngeal cancer surgery. Patients who underwent oral or oropharyngeal cancer resection and neck dissection with either ultrasonic shears (n = 36) or electrothermal bipolar vessel sealing (n = 32) were enrolled. Surgical time, intra-operative bleeding, blood drainage, post-operative pain, neck oedema, complications and hospitalisation duration were compared to those of an historical cohort of 36 patients treated using a cold knife and bipolar forceps. Additionally, a cost-effectiveness evaluation was performed. Ultrasonic shears and, in particular, electrothermal bipolar vessel sealing, were advantageous compared to the traditional techniques. The cost of ultrasonic shears and electrothermal bipolar vessel sealing was completely offset by declining time-driven costs for the surgical team and operating theatre. Ultrasonic shears and, in particular, electrothermal bipolar vessel sealing, are more advantageous compared to the traditional techniques, from both a clinical and economic point of view.

Diabetes mellitus is the most common endocrine disorder due to carbohydrate metabolism. Also, zinc and its supplements have been used in Indian traditional medicines for treating urinary tract infections. In this work, an attempt has been made to compare the properties of ‘Yashadha Bhasma’ a traditional ayurvedic ZnO supplement for diabetic treatment with the laboratory-synthesized ZnO nanoparticles. The nano-sized ZnO particles are synthesized using co-precipitation method and calcined at 400 °C for further purification. Confirmation of ZnO and presence of Ca and K elements additional to Zn in Yashadha Bhasma is confirmed from XPS. The morphology of ZnO is found to be spherical with average diameter of 15 nm. TEM results show that ZnO rods of Yashadha Bhasma are porous and non-uniform. Glucose degradation studies revealed good performance with ZnO nanoparticles with 80% degradation occurring within 15 min itself. Antibacterial studies also performed well establishing efficacy of ZnO nanoparticles against both gram-positive and gram-negative bacterial strains, thereby establishing suitable material for treating diabetes mellitus and also curing bacterial wound infections arising due to diabetes mellitus.

In Australia, trampolines contribute approximately one-quarter of all childhood play-equipment injuries. The purpose of this study was to gather and evaluate injury data from a nontraditional, 'soft-edged', consumer trampoline in which the equipment injury sources have been designed out. A survey was undertaken in Queensland and New South Wales. The manufacturer of the nontraditional trampoline provided the University of Technology, Sydney, with their Australian customer database. Injury data were gathered in a pilot study by phone interview, then in a full study through an email survey. Results from 3817 respondents were compared with earlier Australian and US data from traditional trampolines gathered from emergency departments.   A significantly lower proportion of the injuries caused by falling off or striking the equipment was found for this new design when compared with traditional trampolines both in Australia and in the USA. The age of children being injured on trampolines in Australia was found to be markedly lower than in North America. This research indicates that with appropriate design the more severe injuries on traditional trampolines can be significantly reduced. © 2012 The Authors.

2007-01-01

Our Introduction to Biology course (BIOL 1010) changed in 2004 from a standard instructor-centered, lecture-homework-exam format to a student-centered format that used Web-enhanced, interactive pedagogy. To measure and compare conceptual learning gains in the traditional course in fall 2003 with a section of the interactive course in fall 2004, we created concept inventories for both evolution and ecology. Both classes were taught by the same instructor who had taught BIOL 1010 since 1976, and each had a similar student composition with comparable biological knowledge. A significant increase in learning gain was observed with the Web-enhanced, interactive pedagogy in evolution (traditional, 0.10; interactive, 0.19; p = 0.024) and ecology (traditional, −0.05; interactive, 0.14; p = 0.000009) when assessment was made unannounced and for no credit in the last week of classes. These results strengthen the case for augmenting or replacing instructor-centered teaching with Web-enhanced, interactive, student-centered teaching. When assessment was made using the final exam in the interactive course, for credit and after studying, significantly greater learning gains were made in evolution (95%, 0.37, p = 0.0001) and ecology (143%, 0.34, p = 0.000003) when compared with learning gains measured without credit or study in the last week of classes.

Studies have shown that households using sludge from human excreta for agriculture are at an increased risk of soil transmitted helminths. However, while use of ecological sanitation (EcoSan) latrines is increasing in most African countries including Malawi, few studies have been done to check whether use of such sludge could potentially increase the prevalence of helminthic infections among household members as a results of exposure to faecal sludge/compared to use of traditional latrines. A cross sectional study was done targeting households using EcoSan and traditional pit latrines. Samples were collected from both types of latrines in Chikwawa (rural) and Blantyre (urban) districts. These two districts have a high number of EcoSan latrines in southern region of Malawi. 156 latrines were sampled (n = 95 traditional; n = 61 EcoSan), and processed following standard guidelines using modified triple floatation method. Identification of helminth ova (Ascaris lumbricoides, hookworms, Trichuris trichiura, Taenia spp. and Diphyllobothrium latum) was done using standard microscopy methods. The difference between the prevalence and mean concentration of helminths between the two types of latrines was tested using Chi Square and t test respectively. Of the total latrines tested, 85.9% (n = 134) had at least one species of helminth while 84.6% (n = 132) had at least a STH, with 82.0% (n = 50) in EcoSan and 86.3% (n = 82) in traditional pit latrines. There was no significant difference between the prevalence of helminths in EcoSan and traditional pit latrines [χ 2  = 0.43 (1), P = 0.5]. The prevalence of Ascaris lumbricoides was significantly higher in EcoSan than in traditional pit latrines [χ 2  = 5.44 (1) p = 0.02] while prevalence of hookworms was significantly higher in traditional pit latrines than in EcoSan latrines [χ 2  = 13.98 (1) p < 0.001]. The highest concentration of helminths per gram of faecal sludge was in traditional pit latrines [31.2 (95% CI 19.1-43.2)] than in EcoSan latrines [26.4 (95% CI 16.5-36.3)]. There was no significant difference between overall prevalence of helminths between households using EcoSan and those using traditional pit latrines. However, Ascaris lumbricoides was significantly higher in households using EcoSan latrines. EcoSan users need awareness on safe ways of handling faecal sludge in order to reduce chances of reinfection from Ascaris lumbricoides. Further research should be undertaken on household members to identify those infected and potential routes of infection to enable preventive targeting.

Hispanic Concentrated Poverty in Traditional and New Destinations, 2010-2014.

Ludwig-Dehm, Sarah; Iceland, John

2017-12-01

This paper examines patterns of Hispanic concentrated poverty in traditional, new, and minor destinations. Using data from 2010 to 2014 from the American Community Survey, we find that without controlling for group characteristics, Hispanics experience a lower level of concentrated poverty in new destinations compared to traditional gateways. Metropolitan level factors explain this difference, including ethnic residential segregation, the Hispanic poverty rate, and the percentage of Hispanics who are foreign born. Overall, this study sheds new light on the Hispanic geographic dispersal in the United States and offers support for the argument that the Hispanic settlement into new destinations is associated with lower levels of concentrated poverty.

The primary objective of this study was to investigate how to incorporate human activity information in spatial analysis of crashes in urban areas using Twitter check-in data. This study used the data collected from the City of Los Angeles in the United States to illustrate the procedure. The following five types of data were collected: crash data, human activity data, traditional traffic exposure variables, road network attributes and social-demographic data. A web crawler by Python was developed to collect the venue type information from the Twitter check-in data automatically. The human activities were classified into seven categories by the obtained venue types. The collected data were aggregated into 896 Traffic Analysis Zones (TAZ). Geographically weighted regression (GWR) models were developed to establish a relationship between the crash counts reported in a TAZ and various contributing factors. Comparative analyses were conducted to compare the performance of GWR models which considered traditional traffic exposure variables only, Twitter-based human activity variables only, and both traditional traffic exposure and Twitter-based human activity variables. The model specification results suggested that human activity variables significantly affected the crash counts in a TAZ. The results of comparative analyses suggested that the models which considered both traditional traffic exposure and human activity variables had the best goodness-of-fit in terms of the highest R 2 and lowest AICc values. The finding seems to confirm the benefits of incorporating human activity information in spatial analysis of crashes using Twitter check-in data. Copyright © 2017 Elsevier Ltd. All rights reserved.

2016-01-01

Summary: Traditional microsurgery can lead surgeons to use postures that cause musculoskeletal fatigue, leaving them more prone to work-related injuries. A new technology from TrueVision transmits the microscopic image onto a 3-dimensional (3D) monitor, allowing surgeons to operate while sitting/standing in a heads-up position. The purpose of this study was to evaluate the feasibility of performing heads-up 3D microscopy as a more ergonomic alternative to traditional microsurgery. A feasibility study was conducted comparing heads-up 3D microscopy and traditional microscopy by performing femoral artery anastomoses on 8 Sprague-Dawley rats. Operative times and patency rates for each technology were compared. The 8 microsurgeons completed a questionnaire comparing image quality, comfort, technical feasibility, and educational value of the 2 technologies. Rat femoral artery anastomoses were successfully carried out by all 8 microsurgeons with each technology. There was no significant difference in anastomosis time between heads-up 3D and traditional microscopy (average times, 34.5 and 33.8 minutes, respectively; P = 0.66). Heads-up 3D microscopy was rated superior in neck and back comfort by 75% of participants. Image resolution, field of view, and technical feasibility were found to be superior or equivalent in 75% of participants, whereas 63% evaluated depth perception to be superior or equivalent. Heads-up 3D microscopy is a new technology that improves comfort for the microsurgeon without compromising image quality or technical feasibility. Its use has become prevalent in the field of ophthalmology and may also have utility in plastic and reconstructive surgery. PMID:27579241

The purpose of the present article is to compare the individual, peer, family, and school risk and protective factors for both traditional and cyber-bullying victimization. This article draws on data from 673 students from Victoria, Australia, to examine Grade 7 (aged 12-13 years) predictors of traditional and cyber-bullying victimization in Grade 9 (aged 14-15 years). Participants completed a modified version of the Communities That Care youth survey. There were few similarities and important differences in the predictors of traditional and cyber-bullying victimization. For Grade 9 cyber-bullying victimization, in the fully adjusted model, having been a victim of traditional bullying in Grade 7 and emotional control in Grade 7 were predictors. For Grade 9 traditional bullying victimization, predictors were Grade 7 traditional bullying victimization, association with antisocial peers, and family conflict, with family attachment and emotional control marginally statistically significant. The use of evidence-based bullying prevention programs is supported to reduce experiences of both traditional and cyber-bullying victimization, as is the implementation of programs to assist students to regulate their emotions effectively. In addition, traditional bullying victimization may be reduced by addressing association with antisocial friends, family conflict, and bonding to families. © The Author(s) 2014.

The guinea pig as an animal model for developmental and reproductive toxicology studies.

Rocca, Meredith S; Wehner, Nancy G

2009-04-01

Regulatory guidelines for developmental and reproductive toxicology (DART) studies require selection of "relevant" animal models as determined by kinetic, pharmacological, and toxicological data. Traditionally, rats, mice, and rabbits are the preferred animal models for these studies. However, for test articles that are pharmacologically inactive in the traditional animal models, the guinea pig may be a viable option. This choice should not be made lightly, as guinea pigs have many disadvantages compared to the traditional species, including limited historical control data, variability in pregnancy rates, small and variable litter size, long gestation, relative maturity at birth, and difficulty in dosing and breeding. This report describes methods for using guinea pigs in DART studies and provides results of positive and negative controls. Standard study designs and animal husbandry methods were modified to allow mating on the postpartum estrus in fertility studies and were used for producing cohorts of pregnant females for developmental studies. A positive control study with the pregnancy-disrupting agent mifepristone resulted in the anticipated failure of embryo implantation and supported the use of the guinea pig model. Control data for reproductive endpoints collected from 5 studies are presented. In cases where the traditional animal models are not relevant, the guinea pig can be used successfully for DART studies. (c) 2009 Wiley-Liss, Inc.

Engaging and retaining adolescents in research studies is challenging. Social media offers utility for expanding the sphere of research recruitment. This study examined and compared traditional and Facebook-based recruitment strategies on reach, enrollment, cost, and retention. Substance users aged 13-17 years were recruited through several methods, including social media, a study website, fliers, talks in schools, bus ads, and referrals. Study involvement included a one-time visit and semiannual follow-up surveys. 1265 individuals contacted study personnel; 629 were ineligible; 129 declined; and 200 participants enrolled. Facebook drew the greatest volume but had a high rate of ineligibles. Referrals were the most successful and cost-effective ($7 per enrolled participant); school talks were the least. Recruitment source was unrelated to retention success. Facebook may expand recruitment reach, but had greater financial costs and more ineligible contacts, resulting in fewer enrollees relative to traditional interpersonal recruitment methods. Referrals, though useful for study engagement, did not provide a differential benefit in terms of long-term retention.

Breast reduction has traditionally been performed under general anesthesia with adjunct opioid use. However, opioids are associated with a wide variety of adverse effects, including nausea, vomiting, constipation, postoperative sedation, dizziness, and addiction. This study compares bilateral breast reduction using a multimodal opioid-free pain management regimen vs traditional general anesthesia with adjunct opioids. A total of 83 female patients were enrolled in this study. Group 1 includes a retrospective series of 39 patients that underwent breast reduction via general anesthesia with adjunct opioid use. This series was compared to 2 prospective groups of patients who did not receive opioids either preoperatively or intraoperatively. In group 2, twenty-six patients underwent surgery under intravenous sedation and local anesthesia. In group 3, eighteen patients underwent surgery with general anesthesia. All patients in groups 2 and 3 received preoperative gabapentin and celecoxib along with infiltration of local anesthetics during the operation and prior to discharge to the Post-Anesthesia Care Unit (PACU). Primary outcome measures included the duration of surgery, time from end of operation to discharge home, postoperative opioid and antiemetic use, and unplanned postoperative hospitalizations. When compared to group 1, groups 2 and 3 experienced a shorter time from end of operation to discharge home (P < 0.05), fewer unplanned hospital admissions (P < 0.05), and highly significant decrease in postoperative opioid use (P < 0.001). This multimodal approach allows patients to safely undergo opioid-free bilateral breast reduction either under local or general anesthesia as an outpatient. This method resulted in significantly less morbidity, use of opioids postoperatively, as well as unplanned hospital admissions compared to "traditional" breast reduction under general anesthesia with the use of opioids. 3. © 2017 The American Society for Aesthetic Plastic Surgery, Inc.

Fine-resolution repeat topographic surveying of dryland landscapes using UAS-based structure-from-motion photogrammetry: Assessing accuracy and precision against traditional ground-based erosion measurements

Gillian, Jeffrey K.; Karl, Jason W.; Elaksher, Ahmed; Duniway, Michael C.

2017-01-01

Structure-from-motion (SfM) photogrammetry from unmanned aerial system (UAS) imagery is an emerging tool for repeat topographic surveying of dryland erosion. These methods are particularly appealing due to the ability to cover large landscapes compared to field methods and at reduced costs and finer spatial resolution compared to airborne laser scanning. Accuracy and precision of high-resolution digital terrain models (DTMs) derived from UAS imagery have been explored in many studies, typically by comparing image coordinates to surveyed check points or LiDAR datasets. In addition to traditional check points, this study compared 5 cm resolution DTMs derived from fixed-wing UAS imagery with a traditional ground-based method of measuring soil surface change called erosion bridges. We assessed accuracy by comparing the elevation values between DTMs and erosion bridges along thirty topographic transects each 6.1 m long. Comparisons occurred at two points in time (June 2014, February 2015) which enabled us to assess vertical accuracy with 3314 data points and vertical precision (i.e., repeatability) with 1657 data points. We found strong vertical agreement (accuracy) between the methods (RMSE 2.9 and 3.2 cm in June 2014 and February 2015, respectively) and high vertical precision for the DTMs (RMSE 2.8 cm). Our results from comparing SfM-generated DTMs to check points, and strong agreement with erosion bridge measurements suggests repeat UAS imagery and SfM processing could replace erosion bridges for a more synoptic landscape assessment of shifting soil surfaces for some studies. However, while collecting the UAS imagery and generating the SfM DTMs for this study was faster than collecting erosion bridge measurements, technical challenges related to the need for ground control networks and image processing requirements must be addressed before this technique could be applied effectively to large landscapes.

Integrating Internal Standards into Disposable Capillary Electrophoresis Devices To Improve Quantification

PubMed Central

2017-01-01

To improve point-of-care quantification using microchip capillary electrophoresis (MCE), the chip-to-chip variabilities inherent in disposable, single-use devices must be addressed. This work proposes to integrate an internal standard (ISTD) into the microchip by adding it to the background electrolyte (BGE) instead of the sample—thus eliminating the need for additional sample manipulation, microchip redesigns, and/or system expansions required for traditional ISTD usage. Cs and Li ions were added as integrated ISTDs to the BGE, and their effects on the reproducibility of Na quantification were explored. Results were then compared to the conclusions of our previous publication which used Cs and Li as traditional ISTDs. The in-house fabricated microchips, electrophoretic protocols, and solution matrixes were kept constant, allowing the proposed method to be reliably compared to the traditional method. Using the integrated ISTDs, both Cs and Li improved the Na peak area reproducibility approximately 2-fold, to final RSD values of 2.2–4.7% (n = 900). In contrast (to previous work), Cs as a traditional ISTD resulted in final RSDs of 2.5–8.8%, while the traditional Li ISTD performed poorly with RSDs of 6.3–14.2%. These findings suggest integrated ISTDs are a viable method to improve the precision of disposable MCE devices—giving matched or superior results to the traditional method in this study while neither increasing system cost nor complexity.

Food insecurity is steadily increasing in developed countries. Traditional interventions adopted to tackle food insecurity, like food banks, address the urgent need for food. By contrast, alternative interventions, such as community gardens and kitchens, are oriented towards social integration and the development of mutual aid networks. The objective of this paper is to examine whether the populations served by traditional and alternative interventions in food security differ according to measures of vulnerability. We studied newly registered participants to food security interventions. Participants were selected from a random sample of food security community organizations in a two-stage cluster sampling frame. The categorizing variable was participation in a community organization providing either traditional interventions or alternative interventions. Seven measures of vulnerability were used: food security; perceived health; civic participation; perceived social support of the primary network, social isolation, income and education. Regression multilevel models were used to assess associations. 711 participants in traditional interventions and 113 in alternative interventions were enrolled in the study. Between group differences were found with respect to food insecurity, health status perception, civic participation, education and income, but not with respect to social isolation or perceived social support from primary social network. Traditional and alternative food security interventions seem to reach different populations. Participants in traditional interventions were found to have less access to resources, compared to those in alternative interventions. Thus, new participants in traditional interventions may have higher levers of vulnerability than those in alternative interventions.

To evaluate the academic satisfaction and importance among traditional learning (TL) and problem based learning (PBL) medical students, and to further evaluate the areas of concern in the academic education from the student's point of view. A cross sectional study was conducted at the College of Medicine, King Saud University, Riyadh, Kingdom of Saudi Arabia from May to June 2012. The survey questionnaires were self-administered and consisted of mainly 6 sections: teaching, learning, supervision, course organization, information technology (IT) facilities, and development of skills. A total of 92 TL (males: 66 [71.7%]; females: 26 [28.3%]), and 108 PBL (males: 84 [77.8%]; females: 24 [22.1%]), with a mean age of 21.3 +/- 1.3 (TL), and 20.7 +/- 1.0 (PBL) were included in the study. The overall satisfaction rate was higher in the PBL students when compared with TL students in: teaching (84.7%/60.3%); learning (81.4%/64.5%); supervision (80%/51.5%); course organization (69.3%/46.9%); IT facilities (74.0%/58.9%); and development of skills (79.1%/53.9%).

Technology-enhanced learning (TEL) gives a view to improved education. However, there is a need to clarify how TEL can be used effectively. The study compared students' attitudes and opinions towards a traditional face-to-face course on theoretical radiological science and a TEL course where students could combine face-to-face lectures and e-learning modules at their best convenience. 42 third-year dental students were randomly assigned to the traditional face-to-face group and the TEL group. Both groups completed questionnaires before the beginning and after completion of the course on attitudes and opinions towards a traditional face-to-face lectures and technology-enhanced learning. After completion of the course both groups also filled in the validated German-language TRIL (Trierer Inventar zur Lehrevaluation) questionnaire for the evaluation of courses given at universities. Both groups had a positive attitude towards e-learning that did not change over time. The TEL group attended significantly less face-to-face lectures than the traditional group. However, both groups stated that face-to-face lectures were the basis for education in a theoretical radiological science course. The members of the TEL group rated e-mail reminders significantly more important when they filled in the questionnaire on attitudes and opinions towards a traditional face-to-face lectures and technology-enhanced learning for the second time after completion of the course. The members of the technology-enhanced learning group were significantly less confident in passing the exam compared to the members of the traditional group. However, examination results did not differ significantly for traditional and the TEL group. It seems that technology-enhanced learning in a theoretical radiological science course has the potential to reduce the need for face-to-face lectures. At the same time examination results are not impaired. However, technology-enhanced learning cannot completely replace traditional face-to-face lectures, because students indicate that they consider traditional teaching as the basis of their education.

Importance This study is designed to address the need for evidence-based HIV/STI prevention approaches for drug-involved women under criminal justice community supervision. Objective We tested the efficacy of a group-based traditional and multimedia HIV/STI prevention intervention (Project WORTH: Women on the Road to Health) among drug-involved women under community supervision. Design, Setting, Participants, and Intervention We randomized 306 women recruited from community supervision settings to receive either: (1) a four-session traditional group-based HIV/STI prevention intervention (traditional WORTH); (2) a four-session multimedia group-based HIV/STI prevention intervention that covered the same content as traditional WORTH but was delivered in a computerized format; or (3) a four-session group-based Wellness Promotion intervention that served as an attention control condition. The study examined whether the traditional or multimedia WORTH intervention was more efficacious in reducing risks when compared to Wellness Promotion; and whether multimedia WORTH was more efficacious in reducing risks when compared to traditional WORTH. Main Outcomes and Measures Primary outcomes were assessed over the 12-month post-intervention period and included the number of unprotected sex acts, the proportion of protected sex acts, and consistent condom use. At baseline, 77% of participants reported unprotected vaginal or anal sex (n = 237) and 63% (n = 194) had multiple sex partners. Results Women assigned to traditional or multimedia WORTH were significantly more likely than women assigned to the control condition to report an increase in the proportion of protected sex acts (β = 0.10; 95% CI = 0.02–0.18) and a decrease in the number of unprotected sex acts (IRR = 0.72; 95% CI = 0.57–0.90). Conclusion and Relevance The promising effects of traditional and multimedia WORTH on increasing condom use and high participation rates suggest that WORTH may be scaled up to redress the concentrated epidemics of HIV/STIs among drug-involved women in the criminal justice system.

In the 1990s, the Indonesian government launched programmes to train traditional birth attendants (TBAs) and increase the number of midwives. To identify and compare the factors that influence women's choice of a midwife or a TBA for maternal healthcare in Indonesia. This study used a descriptive design for comparing women's choice of maternal healthcare. The participants were (1) married women, (2) experienced birth within two years, (3) living in a rural or urban village, and (4) capable of communicating in the Indonesia language. Three instruments were used: (1) traditional belief questionnaire, (2) preference for caregiver questionnaire, and (3) women-centered care (WCC) questionnaire which measured women's perceptions of care that they received during pregnancy. A total of 371 women participated in this study. All these subjects answered based on their most recent birth within the last two years. Of the 371 women, 207 (55.8%) chose a midwife and 164 (44.2%) chose a TBA for giving birth. Women choosing midwives were generally satisfied and perceived receiving WCC. Factors determining choice were (1) women's background, (2) perception of WCC, (3) satisfaction, (4) choice of antenatal care (ANC), (5) family encouragement, and (6) traditional beliefs. The choice of caregivers was determined by not only education, parity, usual source of healthcare payment, and family encouragement but also traditional beliefs. Indonesian women's choice of a midwife instead of a TBA for their maternal healthcare resulted in a higher satisfaction of care and more ANC visits. Copyright © 2018 Australian College of Midwives.

Academic activity during internship is essentially practical and ward rounds are traditionally considered the cornerstone of clinical education. However, the efficacy and effectiveness of ward rounds for learning purposes have been under-investigated and it is necessary to assess alternative educational paradigms for this activity. This study aimed to compare the educational effectiveness of ward rounds conducted with two different learning methodologies. Student subjects were first tested on 30 true/false questions to assess their initial degree of knowledge on pneumonia and diarrhoea. Afterwards, they attended ward rounds conducted using an active and a traditional learning methodology. The participants were submitted to a second test 48hours later in order to assess knowledge acquisition and were asked to answer two questions about self-directed learning and their opinions on the two learning methodologies used. Seventy-two medical students taking part in a paediatric clinic rotation were enrolled. The active methodology proved to be more effective than the traditional methodology for the three outcomes considered: knowledge acquisition (33 students [45.8%] versus 21 students [29.2%]; p=0.03); self-directed learning (38 students [52.8%] versus 11 students [15.3%]; p<0.001), and student opinion on the methods (61 students [84.7%] versus 38 students [52.8%]; p<0.001). The active methodology produced better results than the traditional methodology in a ward-based context. This study seems to be valuable in terms of the new evidence it demonstrates on learning methodologies in the context of the ward round. © Blackwell Publishing Ltd 2011.

The Representation of Cultural Heritage from Traditional Drawing to 3d Survey: the Case Study of Casamary's Abbey

In 3D survey the aspects most discussed in the scientific community are those related to the acquisition of data from integrated survey (laser scanner, photogrammetric, topographic and traditional direct), rather than those relating to the interpretation of the data. Yet in the methods of traditional representation, the data interpretation, such as that of the philological reconstruction, constitutes the most important aspect. It is therefore essential in modern systems of survey and representation, filter the information acquired. In the system, based on the integrated survey that we have adopted, the 3D object, characterized by a cloud of georeferenced points, defined but their color values, defines the core of the elaboration. It allows to carry out targeted analysis, using section planes as a tool of selection and filtering data, comparable with those of traditional drawings. In the case study of the Abbey of Casamari (Veroli), one of the most important Cistercian Settlement in Italy, the survey made for an Agreement with the Ministry of Cultural Heritage and Activities and Tourism (MiBACT) and University of RomaTre, within the project "Accessment of the sismic safety of the state museum", the reference 3D model, consisting of the superposition and geo-references data from various surveys, is the tool with which yo develop representative models comparable to traditional ones. It provides the necessary spatial environment for drawing up plans and sections with a definition such as to develop thematic analysis related to phases of construction, state of deterioration and structural features.

Problem-based learning (PBL) has been extensively applied as an experimental educational method in Chinese medical schools over the past decade. A meta-analysis was performed to assess the effectiveness of PBL on students’ learning outcomes in physical diagnostics education. Related databases were searched for eligible studies evaluating the effects of PBL compared to traditional teaching on students’ knowledge and/or skill scores of physical diagnostics. Standardized mean difference (SMD) with 95% confidence interval (CI) was estimated. Thirteen studies with a total of 2086 medical students were included in this meta-analysis. All of these studies provided usable data on knowledge scores, and the pooled analysis showed a significant difference in favor of PBL compared to the traditional teaching (SMD = 0.76, 95%CI = 0.33–1.19). Ten studies provided usable data on skill scores, and a significant difference in favor of PBL was also observed (SMD = 1.46, 95%CI = 0.89–2.02). Statistically similar results were obtained in the sensitivity analysis, and there was no significant evidence of publication bias. These results suggested that PBL in physical diagnostics education in China appeared to be more effective than traditional teaching method in improving knowledge and skills. PMID:27808158

Scientific framework is important in designing curricula and evaluating students in the field of education and clinical practice. The purpose of this study was to examine the effectiveness of non-traditional educational methods on critical thinking skills. A systematic review approach was applied. Studies published in peer-reviewed journals from January 2001 to December 2014 were searched using electronic databases and major education journals. A meta-analysis was performed using Review Manager 5.2. Reviewing the included studies, the California Critical Thinking Dispositions Inventory (CCTDI) and California Critical Thinking Skills Test (CCTST) were used to assess the effectiveness of critical thinking in the meta-analysis. The eight CCTDI datasets showed that non- traditional teaching methods (i.e., no lectures) were more effective compared to control groups (standardized mean difference [SMD]: 0.42, 95 % confidence interval [CI]: 0.26-0.57, p < .00001). And six CCTST datasets showed the teaching and learning methods in these studies were also had significantly more effects when compared to the control groups (SMD: 0.29, 95 % CI: 0.10-0.48, p = 0.003). This research showed that new teaching and learning methods designed to improve critical thinking were generally effective at enhancing critical thinking dispositions.

The objective of this study was to test the hypothesis that an integrated disease management (IDM) protocol (patent-pending), which combines telephonic-delivered disease management (TDM) with a worksite-based primary care center and pharmacy delivery, would yield higher contact and enrollment rates than traditional remote disease management alone. IDM is characterized by the combination of standard TDM with a worksite-based primary care and pharmacy delivery protocol led by trusted clinicians. This prospective cohort study tracks contact and enrollment rates for persons assigned to either IDM or traditional TDM protocols, and compares them on contact and enrollment efficiency. The IDM protocol showed a significant improvement in contact and enrollment rates over traditional TDM. Integrating a worksite-based primary care and pharmacy delivery system led by trusted clinicians with traditional TDM increases contact and enrollment rates, resulting in higher patient engagement. The IDM protocol should be adopted by employers seeking higher returns on their investment in disease management programming.

The effects of 3 types of set configurations (cluster, traditional, and undulating) on barbell kinematics were investigated in the present study. Thirteen men (track and field = 8; Olympic weightlifters = 5) (mean +/- SEM age, 23.4 +/- 1.1 years; height, 181.3 +/- 2.1 cm; body mass, 89.8 +/- 4.2 kg) performed 1 set of 5 repetitions in a cluster, traditional, and undulating fashion at 90 and 120% of their 1 repetition maximum (1RM) power clean (119.0 +/- 4.3 kg). All data were collected at 50 Hz and analyzed with a V-Scope Weightlifting Analysis System. Peak velocity (PV) and peak displacement (PD) were analyzed for each repetition and averaged for each set type. Results indicated that a significantly (p < 0.016) higher PV occurred during the cluster set when compared with the traditional sets at both intensities. PD was significantly higher than traditional sets at the 120% intensity. The present study suggests set configuration can affect PV and PD during clean pulls.

Examine the relation between aspects of gender equality and population health based on the premise that sex differences in health are mainly caused by the gender system. All Swedish couples (98 240 people) who had their first child together in 1978. The exposure of gender equality is shown by the parents' division of income and occupational position (public sphere), and parental leave and temporary child care (domestic sphere). People were classified by these indicators during 1978-1980 into different categories; those on an equal footing with their partner and those who were traditionally or untraditionally unequal. Health is measured by the outcomes of death during 1981-2001 and sickness absence during 1986-2000. Data are obtained by linking individual information from various national sources. The statistical method used is multiple logistic regressions with odds ratios as estimates of relative risks. From the public sphere is shown that traditionally unequal women have decreased health risks compared with equal women, while traditionally unequal men tend to have increased health risks compared with equal men. From the domestic sphere is indicated that both women and men run higher risks of death and sickness when being traditionally unequal compared with equal. Understanding the relation between gender equality and health, which was found to depend on sex, life sphere, and inequality type, seems to require a combination of the hypotheses of convergence, stress and expansion.

The application of nanotechnology in drinking water treatment and pollution cleanup is promising, as demonstrated by a number of field-based (pilot and full scale) and bench scale studies. A number of reviews exist for these nanotechnology-based applications; but to better illustrate its importance and guide its development, a direct comparison between traditional treatment technologies and emerging approaches using nanotechnology is needed. In this review, the performances of traditional technologies and nanotechnology for water treatment and environmental remediation were compared with the goal of providing an up-to-date reference on the state of treatment techniques for researchers, industry, and policy makers. Pollutants were categorized into broad classes, and the most cost-effective techniques (traditional and nanotechnology-based) in each category reported in the literature were compared. Where information was available, cost and environmental implications of both technologies were also compared. Traditional treatment technologies were found to currently offer the most cost-effective choices for removal of several common pollutants from drinking water and polluted sites. Nano-based techniques may however become important in complicated remediation conditions and meeting increasingly stringent water quality standards, especially in removal of emerging pollutants and low levels of contaminants. We also discuss challenges facing environmental application of nanotechnology were also discussed and potential solutions.

Stormwater runoff and associated pollutants from urban areas in the greater Chesapeake Bay Watershed (CBW) impair local streams and downstream ecosystems, despite urbanized land comprising only 7% of the CBW area. More recently, stormwater best management practices (BMPs) have been implemented in a low impact development (LID) manner to treat stormwater runoff closer to its source. This approach included the development of a novel BMP model to compare traditional and LID design, pioneering the use of comprehensively digitized storm sewer infrastructure and BMP design connectivity with spatial patterns in a geographic information system at the watershed scale. The goal was to compare total watershed pollutant removal efficiency in two study watersheds with differing spatial patterns of BMP design (traditional and LID), by quantifying the improved water quality benefit of LID BMP design. An estimate of uncertainty was included in the modeling framework by using ranges for BMP pollutant removal efficiencies that were based on the literature. Our model, using Monte Carlo analysis, predicted that the LID watershed removed approximately 78 kg more nitrogen, 3 kg more phosphorus, and 1,592 kg more sediment per square kilometer as compared with the traditional watershed on an annual basis. Our research provides planners a valuable model to prioritize watersheds for BMP design based on model results or in optimizing BMP selection.

The aim of this study is to build a digital dental model with cone beam computed tomography (CBCT), to fabricate a virtual model via 3D printing, and to determine the accuracy of 3D printing dental model by comparing the result with a traditional dental cast. CBCT of orthodontic patients was obtained to build a digital dental model by using Mimics 10.01 and Geomagic studio software. The 3D virtual models were fabricated via fused deposition modeling technique (FDM). The 3D virtual models were compared with the traditional cast models by using a Vernier caliper. The measurements used for comparison included the width of each tooth, the length and width of the maxillary and mandibular arches, and the length of the posterior dental crest. 3D printing models had higher accuracy compared with the traditional cast models. The results of the paired t-test of all data showed that no statistically significant difference was observed between the two groups (P>0.05). Dental digital models built with CBCT realize the digital storage of patients' dental condition. The virtual dental model fabricated via 3D printing avoids traditional impression and simplifies the clinical examination process. The 3D printing dental models produced via FDM show a high degree of accuracy. Thus, these models are appropriate for clinical practice.

Background Seizure control doesn't represent the only challenging goal in patients with brain tumor-related epilepsy. Side effects have often taken precedence for patients' quality of life. Methods We performed an observational retrospective study on patients with brain tumor-related epilepsy: 35 who had assumed oxcarbazepine monotherapy and 35 patients who had undergone treatment with traditional antiepileptic drugs. Primary variable of efficacy was the mean seizure frequency per month and safety variables were the drop-out for side effects and total incidence of side effects. We applied the Propensity Score technique to minimize selection bias. Results Our results showed a similar efficacy of oxcarbazepine and traditional antiepileptic drugs over time, but the difference in safety and tolerability between the two groups was significant: traditional AEDs caused more side effects, both serious and non serious. Conclusion This study highlights the importance of taking into consideration not only seizure control but also the appearance of side effects when choosing antiepileptic drugs in this patients population.

The present study focuses on the fate of polycyclic aromatic hydrocarbons (PAHs) in soils amended with oil shale ash (OSA). Leachability studies to assess the release of PAHs to the environment are essential before the application of OSA in agriculture. A quantitative estimation of the leaching of PAHs from two types of soil and two types of OSA was undertaken in this study. Two leaching approaches were chosen: (1) a traditional one step leaching scheme and (2) a leaching scheme with pretreatment, i.e.., incubation of the material in wet conditions imitating the field conditions, followed by a traditional leaching procedure keeping the total amount of water constant. The total amount of PAHs leached from soil/OSA mixtures was in the range of 15 to 48 μg/kg. The amount of total PAHs leached was higher for the incubation method, compared to the traditional leaching method, particularly for Podzolic Gleysols soil. This suggests that for the incubation method, the content of organic matter and clay minerals of the soil influence the fate of PAHs more strongly compared to the traditional leaching scheme. The amount of PAHs leached from OSA samples is higher than from soil/OSA mixtures, which suggests soils to inhibit the release of PAHs. Calculated amount of PAHs from experimental soil and OSA leaching experiments differed considerably from real values. Thus, it is not possible to estimate the amount of PAHs leached from soil/OSA mixtures based on the knowledge of the amount of PAHs leached from soil and OSA samples separately.
