Shortened IV Antibiotic Course for Uncomplicated, Late-Onset Group B Streptococcal Bacteremia
Authors: Coon Eric R. , Srivastava Raj , Stoddard Greg , Wilkes Jacob , Pavia Andrew T. , Shah Samir S.
Published: October 2018

BACKGROUND:

Guidelines recommend a prolonged course (10 days) of intravenous (IV) antibiotic therapy for infants with uncomplicated, late-onset group B Streptococcus (GBS) bacteremia. Our objective was to determine the frequency with which shorter IV antibiotic courses are used and to compare rates of GBS disease recurrence between prolonged and shortened IV antibiotic courses.

METHODS:

We performed a multicenter retrospective cohort study of infants aged 7 days to 4 months who were admitted to children’s hospitals in the Pediatric Health Information System database from 2000 to 2015 with GBS bacteremia. The exposure was shortened IV antibiotic therapy, defined as discharge from the index GBS visit after a length of stay of ≤8 days without a peripherally inserted central catheter charge. The primary outcome was readmission for GBS bacteremia, meningitis, or osteomyelitis in the first year of life. Outcomes were analyzed by using propensity-adjusted, inverse probability–weighted regression models.

RESULTS:

Of 775 infants who were diagnosed with uncomplicated, late-onset GBS bacteremia, 612 (79%) received a prolonged IV course of antibiotic therapy, and 163 (21%) received a shortened course. Rates of treatment with shortened IV courses varied by hospital (range: 0%–67%; SD: 20%). Three patients (1.8%) in the shortened IV duration group experienced GBS recurrence, compared with 14 patients (2.3%) in the prolonged IV duration group (adjusted absolute risk difference: −0.2%; 95% confidence interval: −3.0% to 2.5%).

CONCLUSIONS:

Shortened IV antibiotic courses are prescribed among infants with uncomplicated, late-onset GBS bacteremia, with low rates of disease recurrence and treatment failure.

Published: October 2018

The key technology for the production of aerated concrete, using sedimentary fly ash to replace the new fly ash, is of enormous interest to the concrete industry. The chemical composition, mineral composition and microstructure of the sedimentary fly ash in Qian-Xi, Gui-Yang and Qing-Zhen power plants are presented. The activity of the sedimentary fly-ash-aerated concrete was tested in detail by employing grinding, mineral admixtures and chemical admixtures. The results show that the sedimentary fly ash is essentially low-calcium fly ash. The mineral composition of the sedimentary fly ash is basically the same as that of the new fly ash. The compressive strength and flexural strength of the ground fly ash specimens are larger than that of untreated fly ash. The use of mineral admixtures SH1 and SH2 for sedimentary fly-ash-aerated concrete can increase the compressive and flexural strength. The excitation effects of SIII activator, SIV activator and SV activator are better than those of other activators. The best chemical admixture is calcium oxide (CaO)–SIV activator. These studies are of significance for the use of sedimentary fly ash in aerated concrete. This study provides a new way to eliminate sedimentary fly ash.

Authors: Alekseev Valery I.
Published: October 2018

Based on the new concept of the V. Bolshakov's orbital theory of paleoclimate, as well as the multiscale time-series wavelet decomposition method, and neural network fuzzy inference rules, the paper derives a predicted curve for the so-called orbital-climate diagram (OCD) in the ratio of  (eccentricity, orbit inclination, precession) within the time interval from -1000 kyr in the past to 100 kyr in the future since modern times. This diagram features the Earth climate change caused by an insolation change to be the principal factor of the climate change, driven by Earth's orbital elements changes. Efficiency of the time-series forecast method is proved by the obtained predicted OCD trajectory verification within the past 100 kyr period and other paleoclimate data with a correlation coefficient 0.93.

Authors: Xu Yi , Gao Hong
Published: October 2018

Abstract: This paper introduces FormantPro, a Praat-based tool for large-scale, systematic analysis of formant movements, especially for experimental data. The program generates a rich set of output metrics, including continuous contours like time-normalized formant trajectories and formant velocity profiles suitable for direct graphical comparisons, and discrete measurements suitable for statistical analysis. It also allows users to generate mean trajectories and discrete measurements averaged across repetitions and speakers. As an illustration of its usage, data from a preliminary study of syllable segmentation in Mandarin were presented. The alignment of continuous formant trajectories enabled by FormantPro provides evidence that the temporal scopes of consonants and vowels are very different from those based on conventional views, and that acoustic and articulatory boundaries of segments are fundamentally similar.Keywords: FormantPro; formant trajectories; syllable segmentation.Resumo: Este artigo apresenta o FormantPro, uma ferramenta que roda no Praat, dedicada à análise sistemática e em larga escala dos movimentos de formantes, especialmente para dados de natureza experimental.

Acoustic Correlates of Prosodic Boundaries in French A Review of Corpus Data / Correlatos acústicos de fronteiras prosódicas em francês: uma revisão de dados de corpora
Authors: Christodoulides George
Published: October 2018

Abstract: In this article we investigate the acoustic correlates of prosodic boundaries in French speech. We compare the prosodic structure annotation performed by experts in two multi-genre corpora (Rhapsodie and LOCAS-F). A uniform analysis procedure is applied to both corpora. The results show that the main acoustic correlates of prosodic boundaries are silent pauses and pre-boundary syllable lengthening. Pitch movements contribute to the perception of boundaries but are essentially correlates of boundary function, rather than boundary strength. Two levels of four-level annotation of boundary strength in the Rhapsodie corpus (periods and packages) correspond to the two-levels of strength in the LOCAS-F corpus.Keywords: prosody; speech segmentation; prosodic boundaries; corpus linguistics; French.Resumo: Neste artigo investigamos os correlatos acústicos de fronteiras prosódicas da fala em língua francesa. Comparamos a anotação da estrutura prosódica efetuada por anotadores experts em dois corpora multigêneros (Rhapsodie e LOCAS-F). Um procedimento de análise uniforme é aplicado a ambos os corpora. Os resultados indicam que os principais correlatos acústicos de fronteiras prosódicas são pausa silenciosa e alongamento da sílaba pré-fronteira. Movimentos de pitch contribuem para a percepção de fronteiras mas são essencialmente correlatos de funções de fronteira, e não de força de fronteira. Dois dos níveis de anotação dos quatro níveis de anotação de força de fronteira do corpus Rhapsodie (períodos e pacotes) correspondem aos dois níveis de intensidade do corpus LOCAS-F.Palavras-chave: prosódia; segmentação da fala; fronteiras prosódicas; linguística de corpus; francês.

Many refugees will face unique socio-emotional stressors before, during, and after resettling in their new home country. The program presented herein focuses on the use of para-professionals, peer educators, from within refugee communities to build upon the Center for Torture and Trauma Survivors Clubhouse model. Group leaders seek to provide supports that will: 1) decrease feelings of isolation; 2) build community networks and; 3) increase feelings of empowerment within the community. To accurately represent the fluidity of the refugee population in this metropolitan region, background is presented on an established refugee population from Iraq and a more recent influx of refugees of Bhutan (ethnic Nepali). The juxtaposition of the two groups underscores the importance of presenting a dynamic program that is peer-led to provide the supports necessary to acclimate to their new environment. Program evaluation results from groups run in 2016-2017 indicate that the groups have been successful in helping participants make friends, get information, become more independent, and feel better about life in America. Additionally, participants report a significantly higher number of individuals who they can “talk to about problems or worries” and connect to with a sense of trust within their ethnic community. Finally, the utility of other therapeutic and support processes, such as horticultural and expressive arts therapies, are discussed apropos work with refugee populations.
Environmental Migration: Social Work at the Nexus of Climate Change and Global Migration
Authors: Powers Meredith C. F. , Schmitz Cathryne A. , Nsonwu Christian Z. , Mathew Manju T.
Published: October 2018

Environmental migrants are caught at the nexus of the climate crisis and the global migrant crisis. The problems of the migrant crisis are recognized globally as they are linked to the complex issues being addressed by the United Nations’ Sustainable Development Goals. The complexity of the issues makes it difficult to grasp the breadth and depth of this crisis. As a result, it can be understood as one of the “wicked problems” requiring us to respond through a lens that recognizes the interconnections of humans and the broader ecosystems within the physical surroundings. When approaching the migrant crisis from this perspective, professionals are challenged to create transdisciplinary, community-based response systems which are holistic, multi-pronged, and inclusive of migrants’ voices and strengths. Storytelling provides a venue for highlighting migrants' voices, engaging in change, and creating the space for individual and collective healing. Social workers are increasingly being called upon to become trained in this practice and to engage in complex change systems alongside other disciplines and community members. As they provide prevention, mitigation, resettlement, and relief efforts, social workers become a part of a global community of leaders engaged in transformative change. By working to address these challenges, they are securing a better world not only for environmental migrants, but also for our planet as a whole.

Published: October 2018

The leading sector of the South of Russia is crop production and livestock-raising with a relatively high risk. Animal husbandry in the region is facing a crisis; the structure and size of herds have sharply decreased. The cost of livestock products and the gap in the rate of its growth are constantly growing. There were problems with fodders and their structural and nutritional imbalance. There is a shortage of meat and dairy products. The volume of gross production for the period from 2005 to 2013 is provided by domestic and foreign meat imports which increased 3-fold. Methods. An analytical study on the state of animal husbandry is conducted on the basis of reports and statistical materials. The system "natural resource potential – industry sector" is described. Analysis of the current state of the industry is aimed at determining the methods of making decisions on land use management on the example of the structural and functional model of development of the agricultural enterprises. Results. At the present time, conditions arise when it is necessary to shift to a new scientifically grounded structural and functional model of the spatial organization of the enterprises. This will allow implementing the strategy of ecoadaptive intensification of grassland production, since the value of cultivated pastures is determined by high proportion of forage grasses in the feed balance and their huge ecological function. Conclusion. This structural and functional approach is based on the consolidation of the territory of agrarian enterprises and the phased subsequent replacement of biological species with different life cycle duration. In this case, the result is the rapid achievement of the maximum productivity of species with low competitive ability which will lead to short payback period.

Published: October 2018

This paper presents a peer comparison between the integration and simplification concepts of zero-voltage-transition (ZVT) circuits applied to voltage fed three-phase inverters used in industrial adjustablespeed drives. Initially, both concepts are defined and their main advantages and limitations are identified. Thereafter, a comparison is made between two selected topologies, considering modulation strategies, main and auxiliary circuit losses and the harmonic content of the inverter output voltage. It is demonstrated that when the load demands a voltage with low harmonic content, the simplified ZVT topologies are recommended and when the number of components is the main concern, the integrated ZVT topologies may be the best choice. Finally, experimental results for the selected topologies operating at 1.5 kW and 20 kHz are presented in order to confirm the comparative analysis carried out. The simplified ZVT topology presented an efficiency of 98.1% at nominal operation while the integrated ZVT topology presented an efficiency of 97.2% at the same condition.

Este artigo apresenta a modulação PWM híbrida para conversores fonte-Z. A técnica combina a teoria do PWM vetorial com a fácil implementação do PWM escalar. Esta estratégia reduz o número de operações matemáticas do algoritmo. A introdução da razão de distribuição de roda livre nesta técnica, permite o desenvolvimento de uma abordagem sistemática para a implementação de técnicas convencionais (vetores nulos divididos igualmente entre o início e o final do período de chaveamento) ou de estratégias modificadas (com redução das perdas de chaveamento por grampeamento), ou ainda inclusão do vetor nulo de curto-circuito (shootthrough) inerente ao inversor fonte-Z. Além disso, o artigo propõe um algoritmo simples para geração da modulação híbrida para o inversor fonte-Z. Simulações e resultados experimentais demonstram a validade do método proposto.

Published: October 2018

One hundred twenty-three samples of 13 different concentrate feeds were collected from 45 dairy farms distributed all over the Varanasi municipal Corporation and these concentrate feeds were analyzed for proximate composition, fibre fractions, macro and micro mineral profilesto explore the suitable nutritional intervention for optimum production of dairy animals. It was observed that, mustard cake and linseed cakes were the major protein source for dairy farms. Linseed cake had comparatively high protein content than mustard cake (30.95 vs. 27.58%). Samples of compounded cattle feeds collected from study area had maximum CF (13.95%) and AIA (2.58%) content. Rice Bran had the maximum NDF and hemicelluloses while mustard cake contained highest ADF, cellulose and lignin levels. Wheat bran contained least NDF and hemicelluloses while maize grain contained least ADF, cellulose and lignin among all the concentrates. Maize grain was found to contain minimum concentration of several macro and micro minerals like Mg, Na, K, Cu, Zn, Mn and Co. Among all the concentrate feeds, compounded cattle feeds had maximum concentration of major minerals viz., Ca, P, Mg and Na while K and S and micro minerals like Cu, Zn, Mn, Fe, Co, Mo and Se were in optimum concentration in it. This is attributed to additional supplementation of these minerals while formulating the compounded feeds. Different, concentrate feed contained varying amount of one or the other macro and micro mineral and therefore, individual concentrate ingredient was always deficient in some minerals which always demands additional supplementation of these minerals even when concentrate ration is fed to livestock.

Authors: Garro-Monge Giovanni , Jiménez-Quesada Karol , Pérez-Méndez Raquel
Published: October 2018

Las plantas del género Phyllanthus son actualmente investigadas por su habilidad para producir compuestos fenólicos con alta capacidad antioxidante. Además, diversos estudios han revelado que estas plantas poseen metabolitos (filantósidos y lignanos) que pueden inducir la apoptosis celular, lo que les proporciona un gran potencial para posibles tratamientos de prevención contra el cáncer. En este trabajo, se llevó a cabo la introducción in vitro de semillas de P. acumminatus; se logró el cultivo in vitro del material vegetal, y las vitro-plantas fueron utilizadas en ensayos de inducción de raíces pilosas, mediante transformación genética con Agrobacterium rhizogenes cepa Ar15834. El tratamiento más favorable para la inducción de estos cultivos organogénicos consistió en el uso de estacas de aproximadamente 1-2 cm, a las cuales se les hicieron cortes transversales con un bisturí, para luego ser inoculadas en el cultivo bacteriano (OD600: 0.6-1).  Las estacas fueron colocadas en medio M & S semisólido al 50% de sales y vitaminas, sin reguladores de crecimiento, por un período de 48 h. Transcurrido este tiempo, las estacas fueron micropropagadas en medio M & S al 100% de sales y vitaminas, complementado con 500 µg/l del antibiótico Ceftriaxona® para erradicar la bacteria. Se logró el  cultivo de las raíces pilosas en medio M & S al 100% de sales y vitaminas, sin reguladores de crecimiento. Por medio del uso de microscopía de luz, se logró la caracterización morfológica de las raíces establecidas, las cuales coinciden plenamente con las típicas raíces pilosas o hairy roots obtenidas por medio del sistema de agro-infección, según la literatura consultada.

miR-3687 Overexpression Promotes Bladder Cancer Cell Growth Through Inhibiting the Negative Effect of FOXP1 on Cyclin E2 Transcription
Authors: Xie Qipeng , Chen Caiyi , Li Haiying , Yan Huiying , Xu Jiheng , Rao Dapang , Zhang Huxiang , Jin Honglei , Huang Haishan , Huang Chuanshu
Published: October 2018

Cyclin E2, a member of the cyclin family, is a key cell cycle-related protein. This protein plays essential roles in cancer progression, and as such, an inhibitor of cyclin E2 has been approved to treat several types of cancers. Even so, mechanisms underlying how to regulate cyclin E2 expression in cancer remain largely unknown. The current study found that miR-3687 is up-regulated in clinical bladder cancer (BC) tumor tissues, TCGA database and human BC cell lines. Inhibition of miR-3687 expression significantly reduces human BC cell proliferation in vitro and tumor growth in vivo, which are concurrently with the induction of G0/G1 cell cycle arrest and downregulation of cyclin E2 protein expression. Interestingly, overexpression of cyclin E2 reversed the inhibition of BC proliferation induced by miR-3687. Mechanistic studies suggest that miR-3687 could bind to the 3'-UTR of foxp1 mRNA, downregulates FOXP1 protein expression, and in turn promotes the transcription of cyclin E2, thereby promoting the growth of BC cells. Collectively, the current study not only establishes a novel regulatory axis of miR-3687/FOXP1 in regard to regulation of cyclin E2 expression in BC cells, but also provides strong suggestive evidence that miR-3687 and FOXP1 may be potentially promising targets in therapeutic strategies of human BC.
A Multi-mode SAR Imaging Chip based on a Dynamically Reconfigurable SoC Architecture Consisting of Dual-operation Engines and Multilayer Switching Network

Published: October 2018

With the development of satellite load technology and very-large-scale integrated (VLSI) circuit technology, on-board real-time synthetic aperture radar (SAR) imaging systems have facilitated rapid response to disasters. Limited by severe size, weight, and power consumption constraints, a key challenge of on-board SAR imaging system design is to achieve high real-time processing performance. In addition, with the rise of multi-mode SAR applications, the reconfiguration of the on-board processing system is beginning to receive widespread attention. This paper presents a multi-mode SAR imaging chip with SoC architecture based on the reconfigurable double-operation engines and multilayer switching network. We decompose the commonly used extend chirp scaling (CS) SAR imaging algorithm into 8 types of double-operation engines according to the computing orders, and design a three-level switching network to connect these engines for data transition. The CPU is responsible for engine scheduling based on data flow driven with instructions to implement each part of the CS algorithm. Thus, multi-mode floating-point SAR imaging processing can be integrated into a single Application-Specific Integrated Circuit (ASIC) chip instead of relying on distributed technologies. As a proof of concept, a prototype measurement system with chip-included board is implemented, and the performance of the proposed design is demonstrated on Chinese Gaofen-3 stripmap continuous imaging. A chip requires 9.2 s, 50.6 s and 7.4 s for a stripmap with 16,384×16,384 granularity, multi-channel stripmap with 65.536×8192 granularity and multi-channel scan mode with 32,768×4096 granularity and 6.9 W for the system hardware to process the SAR raw data.
Form-Finding Analysis on the Rail Cable Shifting System of the Long Span Suspension Bridges
Authors: Quan Pan , Donghuang Yan , Zhuangpeng Yi
Published: October 2018

The determination of the non-loading condition of the rail cable shifting (RCS) system, which consists of main cables, hangers and rail cables, is the premise of the girder erection for the long-span suspension bridges. An analytical form-finding analysis model of shifting system is established according to the basic assumptions of flexible cable structures. Herein, the rail cable is discretized into segmental linear cable elements and the main cable is discretized into segmental catenary elements. Moreover, the calculation and analysis equation of each member and their iterative solutions are derived by taking the elastic elongation of the sling into account. In addition, by taking the girder construction of Aizhai suspension bridge as engineering background, a global scale model of the RCS system is designed and manufactured; also the test system and working conditions are established. The comparison between the test results and analytical results shows the presented analytical method is correct and effective. The process is simplified in the analytical method, and the computational results and precision can satisfy the practical engineering requirements. In addition, the proposed method is suitable to apply to the computation analysis of similar structures.

Published: October 2018

Gas-liquid reactors pose transfer difficulties due to diffusion effects. It is necessary to master the aeration and hydrodynamics of the medium to conduct the reaction well and get a good performance. For this purpose, a study in a submerged membrane bioreactor with a useful volume of 30L, consisting of a microfiltration membrane with an average pore size of 0.14 mm having an effective surface area of 0.2 m2 and a PVC cylindrical air diffuser of radius 4 cm has been studied. The saline tracing method associated with a conductimetric follow-up made it possible to determine the residence times and the mixing time in the reactor at 4 different points both in recirculation and in the absence of recirculation. Gas retention was measured by the manometric method. The experiments were carried out at different temperatures of 25 ° C, at 45 ° C, with a variable air flow rate of 0.5 to 16 mL / s and different solutions (osmosis water, ammonium formate solution, solution ammonium formate + salt, synthetic rubber effluent). The results show that the mixing time varies from one point to another and the recirculation of the mixture reduces the mixing time. One of the positions is limiting, the transfer is done most by diffusion with a mixing time of 115 min without circulation and 65 min with circulation. Gas retention increases with aeration rate and temperature. On the other hand, the more the medium becomes rich in organic substances, the more the gaseous retention decreases. The homogeneous fine-bubble regime is obtained for an air flow rate of between 3 and 10 mL / s of aeration. Beyond this flow rate, the regime becomes heterogeneous without a transition phase for ammonium formate and formate ammonium + salt solutions.
Controlling Data Flows in Computer Networks
Authors: AlRababah Ahmad AbdulQadir
Published: October 2018

In computer networks, loss of data packets is inevitable, in particular, because of the buffer memory overflow of at least one of the nodes located on the path from the source to the receiver, including the latter. Such losses associated with overflows are hereinafter referred to as congestion of network nodes. There are many ways to prevent and eliminate overloads; these methods, in the majority, are based on the management of data flows. A special place is taken by the maintenance of packages, taking into account their priorities. The article considers a number of original technical solutions to improve the quality of control and reduce the required amount of buffer memory of network nodes. The ideas of these solutions are quite simple for their implementation in the development of appropriate software and hardware for telecommunication devices.

Self-consciousness can be considered as the internal disposition to direct attention to oneself. This dispositional tendency can be focused on private aspects of the self, but also on public characteristics of the individual. We examine self-consciousness in online consumer behavior. This concept has been poorly investigated in consumer research. The main objective of this paper is to analyze the influence of the dimensions of self-consciousness in consumer adoption of online shopping. This study is based on a sample of 725 Spanish undergraduates. Results indicated that public self-consciousness is a significant predictor of the adoption of online shopping.

Published: October 2018

A fluid power industry powering the agricultural machinery faces big challenges nowadays. An issue of energy saving has become important due to increasing fuel costs and more stringent emissions regulations impacting vehicle development. A recent study conducted by the U.S. Department of Energy shows that the efficiency of fluid power averages 21 percent. This offers a huge opportunity to improve the current state-of-the-art of fluid power machines, in particular to improve the energy consumption of current applications and create innovative solutions. To increase energy efficiency of fluid power systems reduction of throttling losses and potential energy recovery strategies are needed. Aim of this work is to present classification of current energy saving architectures and aid the development of new techniques for mobile fluid power machines.

The aims of this study is to determine the level of correlation between the ability of concept mathematics with the ability of teaching for mathematics students in mathematics education program. Referring to the purpose, this research is a correlational research using quantitative approach on 56 students of mathematics education who are taking courses Kajian Pengembangan Matematika Sekolah 3 (KPMS3). The data obtained using the test, namely the ability of concepts mathematics test and results of teaching practice. The results of data were analyzed using Pearson Product Moment to see correlation level, while hypothesis test of this research using Independent t-test with SPSS program. Results of data processing obtained that the level of correlation is 0.133 with significance 0.173. The result means that in this class, the ability of mathematics concept has a very low level of correlation, with meaning that the ability teaching math of students is not only influenced by the ability of mathematics concept. The result of processing data also supported by a significance level of 0.173, which can be concluded that there is no influence between the ability of mathematics concept with the ability of teaching mathematics on mathematics students. There is a need for further research related to the readiness of prospective teachers before teaching practice in schools.
Approaches to and Treatment Strategies for Playing-Related Pain Problems Among Czech Instrumental Music Students: An Epidemiological Study
Authors: Ioannou Christos I , Altenmuller Eckart
Published: October 2018

The current study examined the severity of playing-related pain (PRP) problems among music students at the Prague State Conservatoire, as well as the various treatment methods used by these students and how they approach and deal with these phenomena while studying. In total, 180 instrumental
students participated and completed a paper questionnaire. Of these, 88.9% reported that they had experienced PRP at least once in their lives, with 12.6% experiencing pain every time they play. The onset of PRP seemed to coincide with the transition period on entry to the conservatoire and
was associated with the increase in hours of practice. Specific body regions associated with playing each particular instrument were most frequently affected, with females being more susceptible than males to the development of PRP. An alarming 35% of the affected students tended not to seek
help at all, whereas those who did tended to seek advice first from their instrument tutor and second from medical doctors. Most students who visited doctors reported that medical treatments only partially helped them to overcome PRP problems. The most frequent treatment methods used were
resting, gel or creams, and physical exercises. Students believed that inappropriate posture played a key role in the development of their PRP problems. Finally, students indicated a willingness to be aware of and educated about PRP issues during their studies. Further exploration of PRP problems
among student musicians is warranted. Better understanding of differing attitudes toward, use of, and efficiency of various treatment methods after the occurrence of PRPs will provide additional insight for prevention and treatment.
Profiles in Performing Arts Medicine Courage—A Tribute to Dr. Alice Brandfonbrener
Authors: Manchester Ralph A
Published: October 2018

I was honored and privileged to join Dr. Robert Sataloff in delivering a tribute to Dr. Alice Brandfonbrener at the 2015 Symposium on the Medical Problems of Performing Artists in Snowmass, Colorado. As virtually everyone who reads this journal knows, Dr. Brandfonbrener organized the
first symposium (then focused on the medical problems of musicians), was the founding editor of Medical Problems of Performing Artists, and was the first president of the Performing Arts Medicine Association. She died in 2014, just prior to last year’s symposium. This year, after Dr.
Sataloff presented a very engaging overview of Alice’s career and impressive accomplishments, I gave a short address that was based on some of the editorials Alice wrote in this journal during her 20 year tenure as editor. I have chosen a few examples of how the courage that she demonstrated
in launching an international medical conference, a peer-reviewed medical journal, and a professional association continued to present itself in her writing.
Conditioning Methodologies for DanceSport: Lessons from Gymnastics, Figure Skating, and Concert Dance Research
Authors: Outevsky David , Martin Blake CW
Published: October 2018

OBJECTIVES: Dancesport, the competitive branch of ballroom dancing, places high physiological and psychological demands on its practitioners, but pedagogical resources in these areas for this dance form are limited. Dancesport competitors could benefit from strategies used in other
aesthetic sports. In this review, we identify conditioning methodologies from gymnastics, figure skating, and contemporary, modern, and ballet dance forms that could have relevance and suitability for dancesport training, and propose several strategies for inclusion in the current dancesport
curriculum. METHODS: We reviewed articles derived from Google Scholar, PubMed, ScienceDirect, Taylor & Francis Online, and Web of Science search engines and databases, with publication dates from 1979 to 2013. The keywords included MeSH terms: dancing, gymnastics, physiology, energy metabolism,
physical endurance, and range of motion. Out of 47 papers examined, 41 papers met the inclusion criteria (validity of scientific methods, topic relevance, transferability to dancesport, publication date). Quality and validity of the data were assessed by examining the methodologies in each
study and comparing studies on similar populations as well as across time using the PRISMA 2009 checklist and flowchart. RESULTS: The relevant research suggests that macro-cycle periodization planning, aerobic and anaerobic conditioning, range of motion and muscular endurance training, and
performance psychology methods have potential for adaptation for dancesport training. CONCLUSIONS: Dancesport coaches may help their students fulfill their ambitions as competitive athletes and dance artists by adapting the relevant performance enhancement strategies from gymnastics, figure
skating, and concert dance forms presented in this paper.
