Factors Influencing Publication Rates of Abstracts Presented at the ADEA Annual Session & Exhibition

Factors related to the path of abstracts from presentation at a conference to publication as a full article have been analyzed in the medical field, but only a few studies have been performed in dentistry. This study investigated the rate of publication of articles based on abstracts presented at the American Dental Education Association (ADEA) Annual Session & Exhibition in 2002 and 2003 and the time lag to publication. This study also aimed to characterize the abstracts and subsequent articles and determine if there were any significant factors related to expansion of an abstract into a full manuscript. A total of 370 abstracts met the inclusion criteria and were examined for this study. Subsequent published articles were located using a standard PubMed search. Descriptive statistics and bivariate analyses were used to analyze the data collected (alpha=0.05). Results suggest that there was a low (19 percent) publication rate for articles based on abstracts presented at the meetings studied. The median time between abstract presentation and article publication was ten months. Factors that showed significant correlation to likelihood of article publication were multiple affiliations, presence of analytical statistics, and, to a lesser extent, funding. We suggest that presenters at these meetings should expand their abstracts into full manuscripts and seek to publish them in peer-reviewed journals for the benefit of the profession.

Wax Teeth and Metallic Superstructure Trials at the Same Session: Simplified Technique for Implant-Supported Prosthesis

This clinical report describes a method to reduce the number of clinical sessions for the rehabilitation of implant-supported fixed dentures through a simplified and versatile procedure indicated mainly for immediate loading. According to this method, the immediate implant-supported fixed dentures for edentulous patients can be safely fabricated within 2 days. In this technique, the teeth in the wax are prepared on a base of light-polymerized resin, and both wax teeth and metallic superstructure trials are accomplished at the same session.

PHYSIOLOGICAL and NEUROMUSCULAR PROFILE DURING A BODYPUMP SESSION: ACUTE RESPONSES DURING A HIGH-RESISTANCE TRAINING SESSION

Oliveira, AS, Greco, CC, Pereira, MP, Figueira, TR, de Araujo Ruas, VD, Goncalves, M, and Denadai, BS. Physiological and neuromuscular profile during a Bodypump session: acute responses during a high-resistance training session. J Strength Cond Res 23(2): 579-586, 2009-The main purposes of this study were 1) to describe and to compare blood lactate ([La]), heart rate (HR), and electromyographic (EMG) parameters during high-repetition training sessions (HRTSs), 2) to analyze the influence of physical fitness levels in these parameters, and, 3) to analyze the relationship between metabolic ([La]) and neuromuscular (EMG) responses during the HRTS. Fifteen healthy untrained women (21.7 +/- 2.1 years) performed an HRTS called Bodypump for 1 hour, which incorporated the use of variable free weights and high repetitions in a group setting. This session involved 10 music selections (M1-M10) containing resistive exercises for different muscle groups. After music selections 2 (M2), 4 (M4), 6 (M6), 7 (M7), and 9 (M9), [La], HR, and EMG (vastus medialis [VM], vastus lateralis [VL], iliocostalis lumborum [IC], and longissimus thoracis <) were determined. The [La] (M2, 4.00 +/- 1.45 mM; M7, 5.02 +/- 1.73 mM) and HR (M2, 153.64 +/- 18.89 bpm; M7, 16.14 +/- 20.14 bpm) obtained at M2 and M7 were similar but were significantly higher than the other moments of the session. However, EMG (root mean square [RMS]) at M2 (VL, VM, and LT) was lower than at M7. There was no significant correlation of strength and aerobic physical fitness with [La], RMS. In the same way, there was no significant correlation of [La] with RMS at M2 and M7. on the basis of our data, we can conclude that metabolic, cardiovascular, and EMG variables present different and independent behavior during an HRTS. Accordingly, for neuromuscular conditions during HRTS, it seems to be enough to induce improvement in the muscular strength of inferior limbs in untrained subjects.

Correlates of session-rate of perceived exertion (RPE) in a karate training session

Objective. The aim of this study was to analyze the relationships between the rate of perceived exertion (RPE) of a whole exercise session (RPE-S) and objective measures of exercise intensity during a karate training session.Methods. Eight well-trained karate athletes performed a single training session involving basic karate techniques and sparring. Heart rate (HR) was continuously monitored, while blood lactate ([lac]13) and rating of perceived exertion using the Borg's 6-20 scale were taken each 10-min during exercise. Athletes were also asked to rate their RPE-S using a modified CR-10 scale 30-min after exercise.Results. Significant relationships (P<0.05) were found between RPE-S and mean values of %HRmax (r(p) = 0.91), %HR reserve (r(p) = 0.87), [lac]b(r(p) = 0.96), and RPE (r(p) = 0.78) during the session, but not between RPE-S and the duration of exercise bout (r(s) = 0.28; P > 0.05). RPE-S was also significantly related (P < 0.05) to percentage of time sustained under ventilatory thresold (VT) (r(p) = 0.96), between VT and respiratory compensation point (RCP) (r(p) = 0.93) and above RCP (r(p) = 0.96).Conclusion. These results suggest RPE-S to be a valid tool for assessing interindividual variations in global exercise intensity during karate training. (C) 2010 Elsevier Masson SAS. All rights reserved.

Global citizens or faraway viewers? São Paulo residents talk about the 2006 Lebanon conflict

As the emergence of a global public sphere becomes a possibility, growing out of denser economic, political and communicative networks as well as demanded by increasingly complex international problems, questions arise about the capacity and willingness of various national publics to engage in the global debate. This paper shows the results of a news reception analysis with the public of the city of São Paulo, Brazil during the months of July-November 2006, when the Lebanon conflict was broadly covered by the Brazilian media. The paper identifies the modes of engagement with the news about the international conflict, the types of reasoning used by these publics in interpreting the news, and the types of debates and conversations they have or don't have about the conflict. Special attention is given to the personal experience of learning about conflicts abroad and to the relationship between this experience and the construction of a new civic identity where participation in global affairs is an important element. The research shows that São Paulo residents are informed and care about international events, but to a large extent lack the resources and the spaces where they could reflect upon them. It also shows that young people tend to experience global events more intensely as part of their world than the general population. © 2008 Springer Science+Business Media, LLC.

Differences between ADEA annual session poster abstracts and their corresponding full published articles

The purpose of this study was to investigate differences between abstracts of posters presented at the 79th (2002) and 80th (2003) Annual Session & Exhibition of the American Dental Education Association (ADEA) and the published full-length articles resulting from the same studies. The abstracts for poster presentation sessions were downloaded, and basic characteristics of the abstracts and their authors were determined. A PubMed search was then performed to identify the publication of full-length articles based on those abstracts in a peer-reviewed journal. The differences between the abstract and the article were examined and categorized as major and minor differences. Differences identified included authorship, title, materials and methods, results, conclusions, and funding. Data were analyzed with both descriptive and analytic statistics. Overall, 89 percent of the abstracts had at least one variation from its corresponding article, and 65 percent and 76 percent of the abstracts had at least one major and minor variation, respectively, from its corresponding article. The most prevalent major variation was in study results, and the most prevalent minor variation was change in the number of authors. The discussion speculates on some possible reasons for these differences.

Biomechanical effect of one session of low-level laser on the bone-titanium implant interface

Low-level laser (LLL) has been used on peri-implant tissues for accelerating bone formation. However, the effect of one session of LLL in the strength of bone-implant interface during early healing process remains unclear. The present study aims to evaluate the removal torque of titanium implants irradiated with LLL during surgical preparation of implant bed, in comparison to non-irradiation. Sixty-four Wistar rats were used. Half of the animals were included in LLL group, while the other half remained as control. All animals had the tibia prepared with a 2 mm drill, and a titanium implant (2.2 × 4 mm) was inserted. Animals from LLL group were irradiated with laser (gallium aluminum arsenide), with a wavelength of 808 nm, a measured power output of 50 mW, to emit radiation in collimated beams (0.4 cm2), for 1 min and 23 s, and an energy density of 11 J/cm2. Two applications (22 J/cm 2) were performed immediately after bed preparation for implant installation. Flaps were sutured, and animals from both groups were sacrificed 7, 15, 30, and 45 days after implant installation, when load necessary for removing implant from bone was evaluated by using a torquimeter. In both groups, torque values tended to increase overtime; and at 30 and 45 days periods, values were statistically higher for LLL group in comparison to control (ANOVA test, p < 0.0001). Thus, it could be suggested that a single session of irradiation with LLL was beneficial to improve bone-implant interface strength, contributing to the osseointegration process. © 2012 Springer-Verlag London Ltd.

Overall and differentiated session ratings of perceived exertion at different time points following a circuit weight training workout

Session ratings of perceived exertion (SRPE) have been considered to provide a quantitative evaluation of the entire exercise session in different types of resistance training. In this study we investigated the ability of SRPE to assess exercise strain in a circuit weight training (CWT) workout and the influence of time lag to report SRPE. Ten healthy male volunteers (22.3±2.8 years, 72.5±6.5kg, and 175±5cm) completed a CWT session involving three circuits of five multiple joint exercises with single sets of 20 repetitions at 30% one repetition maximum (1-RM). Heart rate [63.7-75.0% maximum heart rate (%HRmax)], blood lactate (5.6-7.6mM) as well as overall, chest, and active muscle RPE increased significantly (p<0.05) throughout the CWT, but no significant differences were found between ratings of perceived exertion (RPE) types. Overall, chest and active muscle SRPE were accessed 10 minutes, 20 minutes, and 30 minutes after the workout, with no significant main effects or SRPE type×time interaction being found (p>0.05). Finally, no significant differences (p>0.05) were observed between averaged SRPE and RPE responses (overall: 3.7±0.6 vs. 3.5±0.9; chest: 3.8±0.7 vs. 3.6±0.8; active muscle; 3.7±0.7 vs. 3.5±0.7). These results suggest SRPE, irrespective of the moment at which it is taken, to be a useful tool for assessing global exercise strain in a CWT workout, providing coaches, physicians, and exercisers a practical way for monitoring this type of resistance training. © 2013.
