Abstract
do Nascimento Salvador, PC, Dal Pupo, J, De Lucas, RD, de Aguiar, RA, Arins, FB, and Guglielmo, LGA. The V̇o
2 kinetics of maximal and supramaximal running exercises in sprinters and middle-distance runners. J Strength Cond Res 30(10): 2857–2863, 2016—The aim of this study was to compare the V̇o
2 kinetics parameters during maximal and supramaximal running exercises in sprinters (SPR) and middle-distance runners (MDR). Twelve SPR (age 20.6 ± 3.4 years; and body mass 74.9 ± 6.2 kg) and 10 MDR (age 17.6 ± 1.4 years; and body mass 70.1 ± 11.8 kg) performed, on different days, a maximal incremental running test for determination of the velocity at maximum oxygen uptake (vV̇o
2max) and 2 constant-speed tests for analysis of V̇o
2 kinetics at 100 and 120% of vV̇o
2max. The MDR presented significantly higher values for the critical speed (18.0 ± 1.0 vs. 14.2 ± 1.0 km·h−1), vV̇o
2max (19.4 ± 0.7 vs. 17.2 ± 0.8 km·h−1), and time to exhaustion at 100% (437 ± 53 vs. 366 ± 49 seconds) than the SPR (p ≤ 0.05). However, the SPR demonstrated greater values for the anaerobic distance capacity (281.3 ± 66.1 vs. 208.0 ± 43.4 m). Although the mean response time and the time to attain the V̇o
2max of the V̇o
2 kinetics was higher in the maximal than supramaximal running speed (p ≤ 0.05), no difference was found in these parameters as well for V̇o
2 slow component (p > 0.05) between the groups. This study showed that different aerobic and anaerobic characteristics in MDR and SPR did not affect the V̇o
2 kinetics in maximal and supramaximal intensities within the severe-intensity domain. From a practical perspective, parameters of V̇o
2 response may provide helpful information for training control as the duration of stimulus close to V̇o
2max.

Abstract
Dhahbi, W, Chamari, K, Chèze, L, Behm, DG, and Chaouachi, A. External responsiveness and intrasession reliability of the rope-climbing test. J Strength Cond Res 30(10): 2952–2958, 2016—Although the rope-climbing test (RCT) has been validated for upper-body power assessment of Commando soldiers, the external responsiveness and intrasession reliability of the RCT have not been reported. To examine RCT external responsiveness and intrasession reliability, this study consisted of 2 separate phases. Forty male soldiers belonging to the special units of the National Guard, selected on the basis of their training and specialty operations levels, participated in the first phase of the study to identify the discriminant ability of RCT. This group was then divided into anti-terrorism Commandos (21 soldiers) and Intervention-Brigade (19 soldiers). Only the anti-terrorism Commandos participated in the intrasession reliability study. The Commandos were significantly better than the Intervention-Brigade soldiers on execution time (ET), absolute power output (APO), and relative power output (RPO; p < 0.001). The areas under the receiver operator characteristics curves were all higher than 0.70: 0.91, 0.85, and 0.90 for ET, APO, and RPO, respectively. The RCT provided good external responsiveness; thus, RCT was considered to indicate “good” discriminative ability. No significant difference was found between groups in posttest rating of perceived exertion. The intrasession reliability coefficients were excellent for ET, APO, and RPO (intraclass correlation coefficient [3,1] > 0.90). The standard errors of measurement values for the ET, APO, and RPO were all less than 5% (range: 1.29–1.47%). The main findings of this study suggest that RCT is a tool with both high sensitivity and intrasession reliability, allowing the consistent detection of differences in upper-limb power performance between the 2 military groups of different operational capacity levels.

Abstract
Dalamitros, AA, Zafeiridis, AS, Toubekis, AG, Tsalis, GA, Pelarigo, JG, Manou, V, and Kellis, S. Effects of short-interval and long-interval swimming protocols on performance, aerobic adaptations, and technical parameters: A training study. J Strength Cond Res 30(10): 2871–2879, 2016—This study compared 2-interval swimming training programs of different work interval durations, matched for total distance and exercise intensity, on swimming performance, aerobic adaptations, and technical parameters. Twenty-four former swimmers were equally divided to short-interval training group (INT50, 12–16 × 50 m with 15 seconds rest), long-interval training group (INT100, 6–8 × 100 m with 30 seconds rest), and a control group (CON). The 2 experimental groups followed the specified swimming training program for 8 weeks. Before and after training, swimming performance, technical parameters, and indices of aerobic adaptations were assessed. ΙΝΤ50 and ΙΝΤ100 improved swimming performance in 100 and 400-m tests and the maximal aerobic speed (p ≤ 0.05); the performance in the 50-m swim did not change. Posttraining V̇o
2max values were higher compared with pretraining values in both training groups (p ≤ 0.05), whereas peak aerobic power output increased only in INT100 (p ≤ 0.05). The 1-minute heart rate and blood lactate recovery values decreased after training in both groups (p < 0.01). Stroke length increased in 100 and 400-m swimming tests after training in both groups (p ≤ 0.05); no changes were observed in stroke rate after training. Comparisons between groups on posttraining mean values, after adjusting for pretraining values, revealed no significant differences between ΙΝΤ50 and ΙΝΤ100 for all variables; however, all measures were improved vs. the respective values in the CON (p < 0.001–0.05). In conclusion, when matched for distance and exercise intensity, the short-interval (50 m) and long-interval (100 m) protocols confer analogous improvements in swimming performance, in stroke cycle parameters, and in indices of aerobic adaptations after 8 weeks of training.
Sudden cardiac arrest and coexisting mitral valve prolapse: a case report and literature review
Authors: Ahmed Mohamed , Roshdy Ashraf , Sharma Rajan , Fletcher Nick 
Published: February 2016

Abstract
The aetiology of sudden cardiac arrest can often be identified to underlying cardiac pathology. Mitral valve prolapse is a relatively common valvular pathology with symptoms manifesting with increasing severity of mitral regurgitation (MR). It is unusual for severe MR to be present without symptoms, and there is growing evidence that this subset of patients may be at increased risk of sudden cardiac arrest or death. The difficulty lies in identifying those patients at risk and applying measures that are appropriate to halting progression to cardiac arrest. This article examines the association of mitral valve prolapse with cardiac arrests, the underlying pathophysiological process and the strategies for identifying those at risk.
Long standing healed tubercular kyphosis and overlying skin infection with localized collection: an underreported complication
Authors: Dharmshaktu Ganesh S. 
Published: February 2016

The sequelae of healed post-tubercular spine infection often results in ankylosed and fused vertebrae producing kyphosis of varied presentation. The natural bony ankylosis thus helps stabilization of the diseased segment while the infection heals and is the end result of a successful treatment. The complications related to the residual deformity depend on the site, magnitude and associated degree of damage during the course of disease.

Published: February 2016

Issues in teaching various types of information through web-based instruction are explored. The questions of distinctions between content and process courses are evaluated. Some ways in which the resistance to web based learning as a medium of communication can be broken down are covered. Interdisciplinary thinking offers new solutions and hybrid approaches to emerging challenges of educating over the net. Pulling from the seemingly disparate fields of Accounting &amp; Finance, Chemistry, and Rhetoric &amp; Composition new vectors of thinking can be forged. The authors teach online courses in their disciplines. They have drawn on their experiences and the experiences of others to find solutions to problems encountered with distance education. The medium of education over the Internet blurs traditional distinctions of forms and methods of learning.

Workplace privacy is a growing area of concern for employees, companies, legislatures, and the courts. With increasing pressures to improve productivity and profitability, employers are taking advantage of various methods to monitor and control the activities of their employees – both on and off the job. In addition, improved technology is affecting not only the manner in which employers gather such information, but also the location, time, and way in which employees perform their jobs. A survey was conducted to gather perceptions about whether or not employers should be able to take certain actions or gather certain information in ten specific areas. The results provide insights into the three practices deemed most objectionable as well as the three areas of least concern. Court opinions and the professional literature relating to these topics are reviewed. Finally, the law, literature, and survey results are synthesized to produce a series of practical recommendations to help employers and employees deal with workplace privacy in a legal, practical and constructive manner.

Nuestro país posee una alta prevalencia e incidencia de casos de tuberculosis (para el año 2012 se registró una morbilidad de 105,2 casos por 100 000 habitantes). En el tratamiento de esta patología pueden desencadenarse numerosas reacciones adversas de índole heterogénea, siendo preponderantes las neuropsiquiátricas, por la polifarmacia antibiótica requerida y otros posibles factores de riesgo del usuario. A partir de un caso de psicosis desencadenada por cicloserina en un paciente con tuberculosis multidrogorresistente, revisamos la literatura pertinente y recomendamos la ponderación individualizada del retiro de la medicación desencadenante del efecto adverso, respecto a la necesidad de mantener la cobertura antibiótica imprescindible y adecuada.

Authors: Nizama Valladolid Martín 
Published: February 2016

El presente trabajo busca integrar conceptos actuales acerca de las adicciones y complementar los correspondientes conocimientos convencionales vigentes. Se propone una definición holística de las adicciones, ya que se describe a la adicción como una enfermedad familiar. Entre sus principales características clínicas encontramos diversos conceptos tales como: “maletín de doble fondo”, “paternidad maligna”, “infierno familiar” y disfunción familiar. En tal sentido, se propone una definición familiar para las adicciones describiendo su etiología multicausal: causasecológicas, socioeconómicas, culturales, familiares, psíquicas, biogenéticas, farmacológicas y neurobiológicas,bajo el concepto general de modelo holístico centrado en la familia.

An Improved Method for Determination of Fumigant Degradation Half‐Life in Soil
Authors: Ashworth Daniel J. , Yates Scott R. 
Published: February 2016

Core Ideas
Degradation of fumigants is an important component of their fate and transport.
Traditional measurement of half‐life is limited by the large headspace in an incubation vial.
A novel approach is presented that eliminates the incubation vial headspace.
This novel approach yields shorter fumigant half‐lives due to greater contact with soil.
Using the current approach, measurement of fumigant degradation half‐lives under realistic soil conditions is problematic due to the large headspace that is necessary above the soil during incubation. This results in a poor degree of contact between the fumigant and the soil's degrading surfaces, which differs markedly from field conditions. We report a simple, novel approach for determining fumigant degradation half‐lives in which the fumigant is in complete contact with the soil during incubation (no headspace) and which uses gastight, nonsorbing equipment commonly found in pesticide research laboratories. The approach was tested on a sandy loam soil. At both 23 and 50°C, the novel approach yielded much lower degradation half‐lives for cis‐ and trans‐1,3‐dichloropropene (1,3‐D) isomers and chloropicrin (CP) than the traditional approach. Percentage reductions ranged from 22 to 64% and were greater at the higher temperature. The results suggest that literature‐reported half‐lives of soil fumigants, and consequently their modeled soil–air emission rates, may be overestimated. The novel approach could potentially be applied to determining the degradation kinetics of other classes of volatile chemicals in soil.

Core Ideas
The SMAF efficiently detected soil quality changes under Brazilian tropical conditions.
Soil Quality Index was 0.87 (native vegetation), 0.70 (pasture), and 0.74 (sugarcane).
Sugarcane expansion improves soil quality, mainly due to increasing soil chemical quality.
The SMAF–Soil Quality Index was significantly correlated with soil organic C stocks.
The SMAF is useful for monitoring soil quality changes in Brazilian sugarcane production.
The Soil Management Assessment Framework (SMAF) was developed to evaluate impacts of land use and management practices on soil quality (SQ), but its suitability for Brazilian tropical soils was unknown. We hypothesized that SMAF would be sensitive enough to detect SQ changes associated with sugarcane (Saccharum officinarum L.) expansion for ethanol production. Field studies were performed at three sites across the south‐central region of Brazil, aiming to quantify the impacts of a land use change sequence (i.e., native vegetation–pasture–sugarcane) on SQ. Eight soil indicators were individually scored using SMAF curves developed primarily for North American soils and integrated into an overall Soil Quality Index (SQI) and its chemical, physical, and biological sectors. The SMAF scores were correlated with two other approaches used to assess SQ changes, soil organic C (SOC) stocks and Visual Evaluation of Soil Structure (VESS) scores. Our findings showed that the SMAF was an efficient tool for assessing land use change effects on the SQ of Brazilian tropical soils. The SMAF scoring curves developed using robust algorithms allowed proper assignment of scores for the soil chemical, physical, and biological indicators assessed. The SQI scores were significantly correlated with SOC stocks and VESS scores. Long‐term transition from native vegetation to extensive pasture promoted significant decreases in soil chemical, physical, and biological indicators. Overall SQI suggested that soils under native vegetation were functioning at 87% of their potential capacity, while pasture soils were functioning at 70%. Conversions of pasture to sugarcane induced slight improvements in SQ, primarily because of improved soil fertility. Sugarcane soils are functioning at 74% of their potential capacity. Based on this study, management strategies were developed to improve SQ and the sustainability of sugarcane production in Brazil.
