The goal of this study was to describe the development of equine drug testing in horses in Switzerland. This was achieved through evaluation of a film made by the Institute of Forensic Medicine at the University of Basel entitled 'Doping von Rennpferden' [Doping of Race Horses], toxicological detection, 1962', the analysis of doping test results of the Swiss Equestrian Federation and by interviewing individuals of various professions who were involved in equine drug testing at the time. The study compares early and modern methods of drug testing and highlights the changes in the attitude of equestrian athletes, horse owners and the general public toward doping in equestrian sports. The high sensitivity of modern analytical methods allows the detection of drugs at levels considerably below therapeutic concentrations. This has resulted in a shift from zero tolerance for Controlled Medication Substances to the establishment of sub-therapeutic threshold concentrations. The lists of performance-enhancing drugs used in doping are updated continually. It became clear from this work that in the early 1960s, Switzerland played a leadership role in anti-doping in equestrian sports, and that the efforts to keep the sport free of performance-enhancing drugs remain exemplary.

We surveyed varsity athletes at a Big East university to assess attitudes toward a mandatory drug education and testing program and examined whether there were differences in drug-related attitudes and behaviors based on gender or varsity sport. We found no statistically significant differences in personal drug use behaviors based on gender or team affiliation. Attitudes about drug use and knowledge of a teammate using drugs did show significant differences based on varsity sport. Tennis players were most likely to agree that drug use by college athletes is socially acceptable. Lacrosse players were most likely to know of atleast one teammate using drugs. Overall, attitudes towards the mandatory drug education and testing program were ambivalent. About half of our responding athletes believed drug testing was necessary and discouraged drug use. Only 17% believed that the program was an invasion of privacy.

A plethora of compounds potentially leading to drug candidates that affect skeletal muscle function and, more specifically, mitochondrial biogenesis, has been under (pre)clinical investigation for rare as well as more common diseases. Some of these compounds could be the object of misuse by athletes aiming at artificial and/or illicit and drug-facilitated performance enhancement, necessitating preventive and proactive anti-doping measures. Early warnings and the continuous retrieval and dissemination of information are crucial for sports drug testing laboratories as well as anti-doping authorities, as they assist in preparation of efficient doping control analytical strategies for potential future threats arising from new therapeutic developments. Scientific literature represents the main source of information, which yielded the herein discussed substances and therapeutic targets, which might become relevant for doping controls in the future. Where available, mass spectrometric data are presented, supporting the development of analytical strategies and characterization of compounds possibly identified in human sports drug testing samples. Focusing on skeletal muscle and mitochondrial biogenesis, numerous substances exhibiting agonistic or antagonistic actions on different cellular 'control centers' resulting in increased skeletal muscle mass, enhanced performance (as determined with laboratory animal models), and/or elevated amounts of mitochondria have been described. Substances of interest include agonists for REV-ERBα (e.g. SR9009, SR9011, SR10067, GSK4112), sirtuin 1 (e.g. SRT1720, SRT2104), adenosine monophosphate-activated protein kinase (AMPK, e.g. AICAR), peroxisome proliferator-activated receptor (PPAR)δ (e.g. GW1516, GW0742, L165041), and inhibitory/antagonistic agents targeting the methionine-folate cycle (MOTS-c), the general control non-derepressible 5 (GCN5) acetyl transferase (e.g. CPTH2, MB-3), myostatin (e.g. MYO-029), the myostatin receptor

Historically, dope-testing methods have been developed to target specific and known threats to the integrity of sport. Traditionally, the source of new analytical targets for which testing was required were derived almost exclusively from the pharmaceutical industry. More recently, the emergence of designer drugs, such as tetrahydrogestrinone that are specifically intended to evade detection, or novel chemicals intended to circumvent laws controlling the sale and distribution of recreational drugs, such as anabolic steroids, stimulants and cannabinoids, have become a significant issue. In this review, we shall consider the emergence of designer drugs and the response of dope-testing laboratories to these new threats, in particular developments in analytical methods, instrumentation and research intended to detect their abuse, and we consider the likely future impact of these approaches.

Recently, pharmaceutical industry developed a new class of therapeutics called Selective Androgen Receptor Modulator (SARM) to substitute the synthetic anabolic drugs used in medical treatments. Since the beginning of the anti-doping testing in sports in the 1970s, steroids have been the most frequently detected drugs mainly used for their anabolic properties. The major advantage of SARMs is the reduced androgenic activities which are the main source of side effects following anabolic agents' administration. In 2010, the Swiss laboratory for doping analyses reported the first case of SARMs abuse during in-competition testing. The analytical steps leading to this finding are described in this paper. Screening and confirmation results were obtained based on liquid chromatography tandem mass spectrometry (LC-MS/MS) analyses. Additional information regarding the SARM S-4 metabolism was investigated by ultra high-pressure liquid chromatography coupled to quadrupole time-of-flight mass spectrometer (UHPLC-QTOF-MS).

Recent proposals to punish athletes for taking drugs or to impose mandatory drug testing cannot be defended in ethical terms. Nor is it possible to distinguish consistently between ethical and unethical uses of restorative drugs, additive drugs, painkillers, and recreational drugs. We oppose drugs in sports because they violate the majority notion of acceptable behavior. But such opposition has more to do with defending the ideals of the community than with creating policies that are ethically sound.

Background Doping attitude is a key variable in predicting athletes’ intention to use forbidden performance enhancing drugs. Indirect reaction-time based attitude tests, such as the implicit association test, conceal the ultimate goal of measurement from the participant better than questionnaires. Indirect tests are especially useful when socially sensitive constructs such as attitudes towards doping need to be described. The present study serves the development and validation of a novel picture-based brief implicit association test (BIAT) for testing athletes’ attitudes towards doping in sport. It shall provide the basis for a transnationally compatible research instrument able to harmonize anti-doping research efforts. Method Following a known-group differences validation strategy, the doping attitudes of 43 athletes from bodybuilding (representative for a highly doping prone sport) and handball (as a contrast group) were compared using the picture-based doping-BIAT. The Performance Enhancement Attitude Scale (PEAS) was employed as a corresponding direct measure in order to additionally validate the results. Results As expected, in the group of bodybuilders, indirectly measured doping attitudes as tested with the picture-based doping-BIAT were significantly less negative (η2 = .11). The doping-BIAT and PEAS scores correlated significantly at r = .50 for bodybuilders, and not significantly at r = .36 for handball players. There was a low error rate (7%) and a satisfactory internal consistency (r tt = .66) for the picture-based doping-BIAT. Conclusions The picture-based doping-BIAT constitutes a psychometrically tested method, ready to be adopted by the international research community. The test can be administered via the internet. All test material is available “open source”. The test might be implemented, for example, as a new effect-measure in the evaluation of prevention programs. PMID:24479865

This editorial draws comparisons between the recent revelations of drug misuse in Russian sport, and the State-sponsored programme of the former German Democratic Republic. While 50 years separates these two regimes, there are commonalities. The history of major incidents involving drug abuse by serious national players in sport suggests a 20-year cycle, with the GDR, China and now Russia employing similar strategies. These events underscore the value placed upon international sporting success by politicians.

Since its release as anti-anemic drug, recombinant erythropoietin (rEPO) gradually entered the illicit way to sports competitions as endurance-enhancing drug. Novel modifications biopharmaceutically introduced into the rEPO molecule in the form of carbohydrate or polyethylene glycol moieties made robust and sensitive test methods vital to doping controls in order to provide the necessary tools enabling the conviction of dishonest athletes. Modern protein analysis by means of gel electrophoretic separation and western blotting represents the status quo in rEPO anti-doping analysis. However, new therapeutically promising erythropoietin receptor activating compounds have been developed that exhibit cytokine hormone-mimicking properties but lack any protein structure. Progression to evade parenteral application and substitute for rEPO by low molecular mass and orally available compounds is still one of the major objectives in pharmaceutical research. In this approach, four promising in-house synthesized nonpeptidic erythropoietin mimetic agents, namely compound 129, compound 163, A1B10C1, and A5B10C4 were thoroughly evaluated by employing high-resolution/high-accuracy liquid chromatography tandem mass spectrometry experiments. Characteristic product ions were determined supporting the identification of these drugs and putative metabolites as well as related compounds in future doping controls. Test methods employing direct urine injection and receptor affinity purification strategies were assessed, which demonstrated that EPO receptor purification is of limited utility for nonpeptidic EPOR agonists while direct urine injection allowed for comprehensive method characterization. Thereby, achieved limits of detection were 1 ng/mL for compounds 129/163 and 5 ng/mL for A1B10C1/A5B10C4.

The misuse of anabolic-androgenic steroids (AAS) in sports aiming at enhancing athletic performance has been a challenging matter for doping control laboratories for decades. While the presence of a xenobiotic AAS or its metabolite(s) in human urine immediately represents an antidoping rule violation, the detection of the misuse of endogenous steroids such as testosterone necessitates comparably complex procedures. Concentration thresholds and diagnostic analyte ratios computed from urinary steroid concentrations of, e.g., testosterone and epitestosterone have aided identifying suspicious doping control samples in the past. These ratios can however also be affected by confounding factors and are therefore not sufficient to prove illicit steroid administrations. Here, carbon and, in rare cases, hydrogen isotope ratio mass spectrometry (IRMS) has become an indispensable tool. Importantly, the isotopic signatures of pharmaceutical steroid preparations commonly differ slightly but significantly from those found with endogenously produced steroids. By comparing the isotope ratios of endogenous reference compounds like pregnanediol to that of testosterone and its metabolites, the unambiguous identification of the urinary steroids' origin is accomplished. Due to the complex urinary matrix, several steps in sample preparation are inevitable as pure analyte peaks are a prerequisite for valid IRMS determinations. The sample cleanup encompasses steps such as solid phase or liquid-liquid extraction that are presumably not accompanied by isotopic fractionation processes, as well as more critical steps like enzymatic hydrolysis, high-performance liquid chromatography fractionation, and derivatization of analytes. In order to exclude any bias of the analytical results, each step of the analytical procedure is optimized and validated to exclude, or at least result in constant, isotopic fractionation. These efforts are explained in detail. © 2017 Elsevier Inc. All rights reserved.

Recent exposes of drug use in sports suggest that doping might be more problematic than doping-control test results reveal. A zero-tolerance (ZT) model, which aims to eliminate the use, has dominated the thinking of sport's policy makers over the last 15 years. In light of the limitations associated with ZT-based policy, we propose an alternative policy, one based on controlled use and harm reduction principles. We argue that substance control policies underpinned by harm reduction (HR) principles of social utility and public value will deliver superior social outcomes. First, a harm reduction approach better accommodates the competitive realities of sports and the impact of elite sports' emphasis on performance at all costs. Second, HR prioritises athlete welfare over sport and brand reputation. Finally, while appreciating the regulatory and risk management responsibilities of sports' governing bodies, the HR model offers greater space to the athlete's right to privacy, and right to personal autonomy.

Drug misuse in elite sport is a world-wide phenomenon. This article explores the culture of contemporary sport, provides estimates of doping prevalence, discusses dietary supplementation and highlights major factors influencing high-performance athletes and their support personnel. The aim is to stimulate discussion, informed by the World Anti-Doping Code (WADC), which is particularly relevant to doctors caring for athletes. Online databases were searched for relevant peer-reviewed research from 2009 to 2015. Comparative New Zealand data have been included. Estimates of the prevalence of sports doping range from less than 1% to as high as 52%, dependent upon the demographics of the identified cohort. The culture of elite sport, personal stressors, competitive demands, financial reward and the influence of an 'entourage' of support personnel were identified as critical determinants of drug misuse. The culture of elite contemporary sport is seductive to many aspiring young athletes. To combat drug misuse, effective education should embody moral, ethical and clinical dangers, recognising the importance of support at times of increased athlete vulnerability. Inadvertent doping from product contamination is a recognised risk of unsupervised dietary supplementation. Doctors responsible for the care of high-performance athletes must be cognisant of these issues and the provisions of the WADC.

Drug abuse occurs in all sports and at most levels of competition. Athletic life may lead to drug abuse for a number of reasons, including for performance enhancement, to self-treat otherwise untreated mental illness, and to deal with stressors, such as pressure to perform, injuries, physical pain, and retirement from sport. This review examines the effects of different classes of substances used for doping, side-effects of doping, and treatment of affected athletes. There is variable evidence for the performance-enhancing effects and side-effects of the various substances that are used for doping. Drug abuse in athletes should be addressed with preventive measures, education, motivational interviewing, and, when indicated, pharmacologic interventions.

Amateau and McCarthy's findings published in Nature Neuroscience (June 2004) are noteworthy for suggesting a role for prostaglandins in sexual development. However, evidence suggests that in manipulating PGE2, they unknowingly implicated 3alpha-hydroxysteroid dehydrogenase [E.C. 188.8.131.52], 3(or 17)alpha-hydroxysteroid dehydrogenase [E.C. 184.108.40.206] and their respective products, androsterone (ADT) and epitestosterone (EpiT), in the developmental masculinization of sex behavior. EpiT is generally regarded as a hormonally inactive 17alpha-epimer of testosterone (T). In rats, the kidney is the primary site of EpiT formation, whereas in humans it originates from the gonads, with only a small contribution secreted by the adrenals. Because the ratio of T to EpiT is nearly constant, it is presently used for assessing steroid abuse in competitive sports, where the World Anti-Doping Agency (WADA) considers a T/EpiT ratio >4 evidence of T doping. Despite its central role in the detection of illict anabolic steroid use, our knowledge of factors effecting EpiT production is poor. Clues in the literature, however, reveal that prostaglandin-mediated processes, such as LHRH release, may influence its production. Antimycotics, NSAIDs, and opioid analgesics used in sports medicine are all known to effect prostaglandin E2 synthesis. Primary PGs are potent inhibitors of ADT oxidation, while indomethacin, a prostaglandin blocker, powerfully inhibits 3alpha-HSD reduction and ADT oxidation. This is significant because ADT inhibits the oxidation of EpiT, and may modulate its antiandrogenic and neuroprotective effects. It is hypothesized that the T/EpiT ratio is increased by COX-2 inhibitors and opiod analgesics, and decreased by antimycotics that do not impair testosterone biosynthesis. Given the devastating personal and career consequences that may result from false positive drug tests, substantive research on the effects of PGE2 manipulations on EpiT is warranted.

Clenbuterol (4-amino-α-[(tert-butylamino)methyl]-3,5-dichlorobenzyl alcohol) is approved for human and veterinary use primarily for the treatment of pulmonary afflictions. Despite the authorized administration in cases of medical indications, the misuse of clenbuterol in animal husbandry as well as elite and amateur sport has frequently been reported, arguably due to growth-promoting properties. Due to various recent incidences of doping control specimens containing clenbuterol, strategies towards the discrimination of a surreptitious application from unintended intake via animal-derived edibles or dietary supplements were required. The enantiomeric compositions of clenbuterol in human urine samples derived from administration studies with therapeutic amounts of the β(2)-agonist and authentic doping control specimens were determined. Due to the facts that therapeutic clenbuterol consists of a racemic mixture of (+)- and (-)-stereoisomers and that the first mentioned (dextrorotatory) stereoisomer is retained to a greater extent in edible animal tissue, the differentiation of a recent administration of therapeutic (and thus racemic) clenbuterol from food contamination (stereoisomerically depleted clenbuterol) was considered. Employing deuterated clenbuterol as internal standard, the target analytes were extracted from human urine by means of concerted liquid-liquid and solid-phase extractions and subjected to chiral liquid chromatography hyphenated to high resolution/high accuracy mass spectrometry with electrospray ionization. Both enantiomers of clenbuterol were baseline separated and relative abundances of corresponding labeled and unlabeled stereoisomers were determined, demonstrating that the therapeutic use of clenbuterol results in racemic mixtures in urine for at least 24 h while adverse analytical findings presumably originating from food contaminations can yield (-)-clenbuterol-depleted pairs of analytes. The determination of relative abundances of

With the growing availability of mature systems and strategies in biotechnology and the continuously expanding knowledge of cellular processes and involved biomolecules, human sports drug testing has become a considerably complex field in the arena of analytical chemistry. Proving the exogenous origin of peptidic drugs and respective analogs at lowest concentration levels in biological specimens (commonly blood, serum and urine) of rather limited volume is required to pursue an action against cheating athletes. Therefore, approaches employing chromatographic-mass spectrometric, electrophoretic, immunological and combined test methods have been required and developed. These allow detecting the misuse of peptidic compounds of lower (such as growth hormone-releasing peptides, ARA-290, TB-500, AOD-9604, CJC-1295, desmopressin, luteinizing hormone-releasing hormones, synacthen, etc.), intermediate (e.g., insulins, IGF-1 and analogs, 'full-length' mechano growth factor, growth hormone, chorionic gonadotropin, erythropoietin, etc.) and higher (e.g., stamulumab) molecular mass with desired specificity and sensitivity. A gap between the technically possible detection and the day-to-day analytical practice, however, still needs to be closed.

The inclusion of the psychophysiological measures in the evaluation process and the validation of the instruments applied to Sport Psychology are discusses.
Full Text Available DESCRIPTION The book explains how the usage of drugs in sport came to be considered in terms of "abuse" contrary to be thought of being ethical and supportive to the athletes in the early days of modern sport. PURPOSE The aim of this book is to question of using and abusing drugs in sport at length from a historical perspective. It proposes to discuss the issue as a dilemma of 'good anti-doping' versus 'evil doping'. FEATURES The issues addressed in this book are as following: 1.Sport, drugs and society; 2.Doping and the rise of modern sport, 1876-1918; 3.The science gets serious, 1920-1945; 4. Amphetamines and post-war sport, 1945-1976; 5.The steroids epidemic, 1945-1976; 6.Dealing with the scandal: anti-doping and the new ethics of sport, 1945-1965; 7. Science, morality and policy: the modernisation of anti-doping, 1965-1976; 8.Doping, anti-doping and the changing values of sport. ASSESSMENT This book will be great interest to the sportsmen as well as students, researchers and practitioners in the sport and exercise disciplines whether they work in the laboratory or in the field since it is about a popular topic in sport. It could also be valued as a reference book, because it targets to avoid easy answers to difficult questions in the controversial subject of drug use in sport
Clarke, K S
The Amateur Sports Act of 1978 reconstituted the U.S. Olympic Committee ( USOC ), giving it new responsibilities and opportunities as a unifying force in amateur sports, including sports medicine. Sports medicine is the sum of attentions that promote and protect the health of the active person. Olympic sports medicine includes attention to the needs of both the elite athlete and the developing athlete. In some instances the attentions are the same; in others they are not. Those in Olympic sports medicine must thereby reduce the increasing array of general concepts and issues to the applicable specifics of the respective occasion, sport, and individual. The USOC Sports Medicine Program is guided by a 15-person volunteer Sports Medicine Council and implemented by a core Sports Medicine Division staff. Services are provided at the Olympic training centers in Colorado Springs and Lake Placid and extended through a budding network of colleagues in the field to clusters of athletes across the nations. Organizationally , the Division is composed of departments of biomechanics, sports physiology, clinical services, and educational services. Special projects are developed as warranted to provide focal attention to sports psychology, nutrition, chronobiology, vision enhancement, and drug control. The USOC Drug Control Program was born at the 1983 Pan American Games in Caracas after a long gestation period. Drug education in sports has been a frequent activity for the past 20 yr. sometimes focusing on illicit drugs (e.g., marijuana and cocaine) and sometimes on sports performance drugs (e.g., amphetamines and anabolic steroids).(ABSTRACT TRUNCATED AT 250 WORDS)
Despite scientific evidence to the contrary, a popular incremental field test for endurance athletes (Conconi Test) has been uncritically accepted as valid by some coaches and sport scientists. The Conconi Test is assumed a non-invasive measure of the anaerobic threshold through the identification of a coincident deflection ...

Two cases illustrate the recent trend toward testing school employees for drugs and suggest the emerging legal limits on such testing. Four questions are answered concerning court interpretations of statutory and constitutional issues related to drug testing for both personnel and students. (PGD)
Full Text Available As the use of illegal drugs has reached epidemic proportions in schools, educational leaders in the United States have turned to drug testing in attempting to maintain learner discipline. To this end, the United States Supreme Court has addressed the issue twice in the past eight years. In 1995, the Court permitted drug testing in Acton v. Vernonia School District 47J. More recently, in Board of Education of Independent School District No. 92 of Pottawatomie v. Earls (2002, the Court upheld suspicionless drug testing of learners who wished to participate in extracurricular activities. Even though drug testing has yet to emerge as an issue in South Africa, Earls is significant for educational leaders and policy makers in South Africa since it involves concerns under the National Policy on Privacy. More specifically, under Items 20 and 21 of the South African National Policy on the Management of Drug Abuse (SA, 1996b searches and drug testing should only be used where there is reasonable suspicion, the same standard applied by American courts. However, unlike the United States, the South African policy prohibits random searches and/or drug testing. Thus, due to constitutional and educational issues that drug testing raises, a timely discussion of this matter should be of interest to educational leaders and policy makers in South Africa.

The regular monitoring of physical fitness and sport-specific performance is important in elite sports to increase the likelihood of success in competition. This study aimed to systematically review and to critically appraise the methodological quality, validation data, and feasibility of the sport-specific performance assessment in Olympic combat sports like amateur boxing, fencing, judo, karate, taekwondo, and wrestling. A systematic search was conducted in the electronic databases PubMed, Google-Scholar, and Science-Direct up to October 2017. Studies in combat sports were included that reported validation data (e.g., reliability, validity, sensitivity) of sport-specific tests. Overall, 39 studies were eligible for inclusion in this review. The majority of studies (74%) contained sample sizes sport-specific tests (intraclass correlation coefficient [ICC] = 0.43-1.00). Content validity was addressed in all included studies, criterion validity (only the concurrent aspect of it) in approximately half of the studies with correlation coefficients ranging from r = -0.41 to 0.90. Construct validity was reported in 31% of the included studies and predictive validity in only one. Test sensitivity was addressed in 13% of the included studies. The majority of studies (64%) ignored and/or provided incomplete information on test feasibility and methodological limitations of the sport-specific test. In 28% of the included studies, insufficient information or a complete lack of information was provided in the respective field of the test application. Several methodological gaps exist in studies that used sport-specific performance tests in Olympic combat sports. Additional research should adopt more rigorous validation procedures in the application and description of sport-specific performance tests in Olympic combat sports.

The aim of the study was to develop and test a methodology in situ, which simulated the consumption of sports drinks. A secondary aim was to assess the acceptability of the method to sedentary participants. To select the sports drink for the study in situ, five commercially available sports drinks were examined for erosive potential in vitro. The study in situ was a single centre, 2-period, 2-treatment crossover study to compare the erosive effect of a commercially available sports drink (Test), with that of mineral water (Control), over 10 day periods on 10 healthy volunteers. Subjects wore upper removable appliances containing two human enamel specimens from 9 a.m. to 5 p.m. The regimen of intake of the drinks was 350 ml in 10, 5-min rest, 650 ml in 25, 5-min rest, 500 ml in 10 and 5-min rest. Measurements of enamel loss were made on samples after 5 and 10 days by profilometry. The in situ study showed a statistically significant difference in erosive potential between the test and control beverages. No specimen exposed to the control beverage displayed appreciable erosion. Erosion occurred with the test drink, but to a variable degree between subjects. The subjects unanimously found the drinking regimen unpleasant. The sports drink caused significantly more erosion in situ than water and as seen in other studies, there was marked variation in susceptibility to erosion between subjects. The new drinking regimen was designed to simulate pre, during and post-exercise intake. Although all the sedentary subjects participating in this study reported that they found the volume of fluids consumed over a short period of time excessive it is unlikely that this would prove problematic in the exercise environment.

This study presents an opportunistic examination of the theoretical tenets outlined in the Sport Drug Control Model(1) using questionnaire items from a survey of 643 elite Australian athletes. Items in the questionnaire that related to the concepts in the model were identified and structural equation modelling was employed to test the hypothesised model. Morality (cheating), benefit appraisal (performance), and threat appraisal (enforcement) evidenced the strongest relationships with attitude to doping, which in turn was positively associated with doping susceptibility. Self-esteem, perceptions of legitimacy and reference group opinions showed small non-significant associations with attitude to doping. The hypothesised model accounted for 30% and 11% of the variance in attitudes to doping and doping susceptibility, respectively. These present findings provide support for the model even though the questionnaire items were not constructed to specifically measure concepts contained in it. Thus, the model appears useful for understanding influences on doping. Nevertheless, there is a need to further explore individual and social factors that may influence athletes' use of performance enhancing drugs. Copyright Â© 2011 Sports Medicine Australia.

Dynamic behaviour of bodies during impact is investigated through impact experiment, the simplest being a normal drop test. Normally, a drop test impact experiment involves measurement of kinematic data; this includes measurement of incident and rebound velocity in order to calculate a coefficient of restitution (COR). A high speed video camera is employed for measuring the kinematic data where speed is calculated from displacement of the bodies. Alternatively, sensors can be employed to measure speeds, especially for a normal impact where there is no spin of the bodies. This paper compares experimental coefficients of restitution (COR) for various sports balls, namely golf, table tennis, hockey and cricket. The energy loss in term of measured COR and effects of target plate are discussed in relation to the material and construction of these sports balls.

There is little data in India on the use of performance enhancing drugs in sports. But personal and incidental information shows that their use is far more extensive than is believed. This use occurs beyond the arena of high-level competitive sports. Even if the guidelines of the national and world anti-doping agencies were to become effective, they would not impact the larger environment where such drug use appears to be extensive. Which ethical guidelines advise the sports medical practitioner in prescribing medicines and training regimes for the athlete? Of particular concern is the role of paediatricians since training for sports or physical fitness is increasingly a youth phenomenon. The following is a discussion note, prompted by personal and anecdotal experience.

Comparisons between reactive agility tests incorporating generic and sport-specific stimuli have been performed only in field-based team sports. The aim of this study was to compare generic (light-based) and sport-specific (live opponent) reactive agility tests in court-based team sport athletes. Twelve semi-professional male basketball players (age: 25.9±6.7 yr; stature: 188.9±7.9 cm; body mass: 97.4±16.1 kg; predicted maximal oxygen uptake: 49.5±5.3 mL/kg 7 min) completed multiple trials of a Reactive Agility Test containing light-based (RAT-Light) and opponent-based stimuli (RAT-Opponent). Multiple outcome measures were collected during the RAT-Light (agility time and total time) and RAT-Opponent (decision time and total time). Mean performance times during the RAT-Light (2.233±0.224 s) were significantly (Pagility time and RAT-Opponent decision time (r10=0.20), while a trivial relationship was apparent between total performance times across tests (r10=0.02). Low commonality was observed between comparable measures across tests (R2=0-4%). Reactive agility tests containing light-based and live opponent stimuli appear to measure different qualities in court-based team sport athletes. Court-based team sport coaches and conditioning professionals should not use generic and sport-specific reactive agility tests interchangeably during athlete assessments.

Agility is an important characteristic of team sports athletes. There is a growing interest in the factors that influence agility performance as well as appropriate testing protocols and training strategies to assess and improve this quality. The objective of this systematic review was to (1) evaluate the reliability and validity of agility tests in team sports, (2) detail factors that may influence agility performance, and (3) identify the effects of different interventions on agility performance. The review was undertaken in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We conducted a search of PubMed, Google Scholar, Science Direct, and SPORTDiscus databases. We assessed the methodological quality of intervention studies using a customized checklist of assessment criteria. Intraclass correlation coefficient values were 0.80-0.91, 0.10-0.81, and 0.81-0.99 for test time using light, video, and human stimuli. A low-level reliability was reported for youth athletes using the video stimulus (0.10-0.30). Higher-level participants were shown to be, on average, 7.5% faster than their lower level counterparts. Reaction time and accuracy, foot placement, and in-line lunge movement have been shown to be related to agility performance. The contribution of strength remains unclear. Efficacy of interventions on agility performance ranged from 1% (vibration training) to 7.5% (small-sided games training). Agility tests generally offer good reliability, although this may be compromised in younger participants responding to various scenarios. A human and/or video stimulus seems the most appropriate method to discriminate between standard of playing ability. Decision-making and perceptual factors are often propositioned as discriminant factors; however, the underlying mechanisms are relatively unknown. Research has focused predominantly on the physical element of agility. Small-sided games and video training may offer effective

Full Text Available The present study was designed to determine which types of specific tests provide an effective evaluation of strength and endurance in highly trained competitive sport climbers. The research process consisted of three basic components: the measurement of selected somatic characteristics of the climbers, the assessment of their physical conditioning, and a search for correlations between the anthropometric and “conditioning” variables on the one hand, and climber’s performance on the other. The sample of subjects consisted of 14 experienced volunteer climbers capable of handling 7a- 8a+/b on-sight rock climbing grades. The strongest correlations (Spearman’s rank were found between climber’s competence and the relative results of the finger strength test (r = 0.7; much lower, but still statistically significant coefficients were found between the level of competence and the results of the muscle endurance tests (r = 0.53 – 0.57. Climbers aspiring to attain an elite level must have strong finger and forearm muscles, but most of all, they must be capable of releasing their potential during specific motor capability tests engaging these parts of the body. The forearm muscles of elite climbers must also be very resistant to fatigue. Since highly trained athletes vary only slightly in body mass, this variable does not have a major effect on their performance during strength and endurance tests.

This paper describes the stages of development of a machine to perform impact tests in sport seats, seats for spectators and multiple seats. This includes reviews and recommendations for testing laboratories that have needs similar to the laboratory where unfolded this process.The machine was originally developed seeking to meet certain impact tests in accordance with the NBR15925 standards; 15878 and 16031. The process initially included the study of the rules and the election of the tests for which the machine could be developed and yet all reports and outcome of interaction with service providers and raw materials.For operating facility, it was necessary to set entirely the machine control, which included the concept of dialogue with operator, the design of the menu screens and the procedures for submission and registration of results. To ensure reliability in the process, the machine has been successfully calibrated according to the requirements of the Brazilian network of calibration.The criticism to this enterprise covers the technical and economic aspects involved and points out the main obstacles that were needed to overcome.

As Australia's peak high-performance sport agency, the Australian Institute of Sport (AIS) has developed this position statement to address the implications of recent advances in the field of genetics and the ramifications for the health and well-being of athletes. Genetic testing has proven of value in the practice of clinical medicine. There are, however, currently no scientific grounds for the use of genetic testing for athletic performance improvement, sport selection or talent identification. Athletes and coaches should be discouraged from using direct-to-consumer genetic testing because of its lack of validation and replicability and the lack of involvement of a medical practitioner in the process. The transfer of genetic material or genetic modification of cells for performance enhancement is gene doping and should not be used on athletes. There are, however, valid roles for genetic research and the AIS supports genetic research which aims to enhance understanding of athlete susceptibility to injury or illness. Genetic research is only to be conducted after careful consideration of a range of ethical concerns which include the provision of adequate informed consent. The AIS is committed to providing leadership in delivering an ethical framework that protects the well-being of athletes and the integrity of sport, in the rapidly changing world of genomic science.

Entrepreneurial marketing of sport increases demands on sport development officers to identify talented individuals for specialist development at the youngest possible age. Talent identification results in the streamlining of resources to produce optimal returns from a sports investment. However, the process of talent identification for team sports is complex and success prediction is imperfect. The aim of this review is to describe existing practices in physiological tests used for talent identification in team sports and discuss the impact of maturity-related differences on the long term outcomes particularly for male participants. Maturation is a major confounding variable in talent identification during adolescence. A myriad of hormonal changes during puberty results in physical and physiological characteristics important for sporting performance. Significant changes during puberty make the prediction of adult performance difficult from adolescent data. Furthermore, for talent identification programs to succeed, valid and reliable testing procedures must be accepted and implemented in a range of performance-related categories. Limited success in scientifically based talent identification is evident in a range of team sports. Genetic advances challenge the ethics of talent identification in adolescent sport. However, the environment remains a significant component of success prediction in sport. Considerations for supporting talented young male athletes are discussed.

This study provides an exhaustive review of 34 peer-reviewed quantitative data-based studies completed on high school and college sports involvement and drug use. The studies reviewed suggest that participation in sport is related to higher levels of alcohol consumption, but lower levels of both cigarette smoking and illegal drug use. Additional research is needed in this domain to further elucidate the relationship between these variables. Copyright (c) 2009 Elsevier Ltd. All rights reserved.

The issue of the expectations of elite athletes, their coaches and non-medically qualified athlete support staff of consultations with sports physicians has not been previously dealt with in the sports medicine literature. As fulfillment of expectations of the content of a consultation may influence patient's satisfaction and clinical outcome, it is important to assess the expectations of athletes and, most importantly, coaches. To assess the expectations and beliefs about fatigue, particularly in relation to blood tests, of athletes, their coaches and support staff in the specific context of tiredness of non-medically qualified sports medicine staff, 22 elite coaches and 62 elite athletes from the Australian Institute of Sport were included in this study. A single questionnaire. The expectation for a blood test at the initial consultation for short-term fatigue was particularly high among athletes (81%) and coaches (91%). This expectation increased in athletes if their performance was worsening. All groups unanimously suggested that a blood test be performed in cases of more prolonged fatigue. Increase in total training load was perceived to be the most important cause of fatigue, but issues relating to sleep were also thought to be highly relevant. All groups suggested that blood tests provide some degree of reassurance, and all groups suggested that the most important blood tests that might be performed related to exclusion of iron deficiency, anaemia and infection. Athletes and their coaches generally expect that blood tests will be performed even when fatigue has been present for athletes, coaches and doctors need to be considered when deciding on whether such testing has to be performed.

Exposure of a drug to irradiation can influence the stability of the formulation, leading to changes in the physicochemical properties of the product. The influence of excipients of frequently used stabilizers is often difficult to predict and, therefore, stability testing of the final preparation is important. The selection of a protective packaging must be based on knowledge about the wavelength causing the instability. Details on drug photoreactivity will also be helpful in order to minimize side-effects and/or optimize drug targeting by developing photoresponsive drug delivery systems. This review focuses on practical problems related to formulation and stability testing of photolabile drugs.
Debate about the ethics of drug control in sport has largely focused on arguing the relative merits of the existing antidoping policy or the adoption of a health-based harm minimisation approach. A number of ethical challenges arising from antidoping have been identified, and a number of, as yet, unanswered questions remain for the maturing ethics of applying harm minimisation principles to drug control for sport. This paper introduces a 'third approach' to the debate, examining some implications of applying a stakeholder theory of corporate social responsibility (CSR) to the issue of doping in sport. The introduction of the stakeholder-CSR model creates an opportunity to challenge the two dominant schools by enabling a different perspective to contribute to the development of an ethically robust drug control for sport.

In France, workplace testing of drugs of abuse and psychotropic drugs is rarely performed; meanwhile it is a major public health problem. Furthermore, France is the European country that has been associated with the highest increase of the use of drugs of abuse, particularly cannabis. So workplace biological screening of drugs of abuse and of psychotropic drugs exposure is of major concern. New analytical techniques have been developed during the last years. The authors will consider analytical screening of drugs of abuse and particularly the comparison of analytical techniques applied to urine and saliva. The advantages and the disadvantages of these two matrices will be considered. Urinary and blood quantification will be reviewed, but also the interest of hair testing to explore chronic exposure. The research of psychotropic drugs in biological fluids is also a part of this paper. New analytical trends are promising and complete analysis of these substances will be soon routinely possible in blood using a single spot test. Copyright © 2012 Elsevier Masson SAS.

In this work, a sensitive nanoflow liquid chromatography high-resolution mass spectrometry screening method has been developed for the determination of multiclass drugs of abuse and sport drugs in human urine. 81 drugs belonging to different multiclass pharmaceuticals were targeted. The method is based on the use of a nanoLC column (75 µm × 150 mm, 3 µm particle size and 100 Å pore) with the nanospray emitter tip integrated so that dead volumes are significantly minimized. Data acquisition method included both full-scan and all ion fragmentation experiments using an Orbitrap analyser (Q-Exactive) operated in the positive ionization mode. To increase laboratory throughput, a dilute-and-shoot methodology has been tested and proposed, based solely on direct urine dilution without further sample workup. Matrix effects were evaluated, showing a negligible effect for all studied compounds when a dilution 1:50 was implemented. Despite this high-dilution factor, limits of quantification were still satisfactory, with values below 5 µg L -1 in most cases, being lower than their minimum required performance limits correspond established by the World Anti-Doping Agency. Therefore, the use of the dilute-and-shoot method with the enhanced sensitivity provided by nanoflow LC setup could be useful tool for the determination of studied compounds in drug testing, thus increasing laboratory performance, because a minimum sample treatment steps are required.

We assessed the potential for harmful messages in online advertisements targeted to youth, using the example of the Canadian "Light It Up" marketing campaign from a large sports corporation. We undertook a cluster randomized controlled trial of 20 secondary school classes in Montreal, Canada. Classes were randomly allocated to view a "Light It Up" advertisement (n = 205) or a neutral comparison advertisement (n = 192). The main outcome measures were self-reports of illicit drug messages in the advertisements. Of the students, 22.9% reported that the "Light It Up" advertisement contained illicit drug messages compared with 1.0% for the comparison advertisement (relative risk, 22.0; 95% confidence interval, 6.5-74.9). Although meant to promote sports, youth in this study believed that the "Light It Up" advertisement was related to illicit drugs. The campaign illustrates how advertisements may inadvertently market unwanted behaviors to children. Copyright © 2015 Society for Adolescent Health and Medicine. Published by Elsevier Inc.

Non-steroidal anti-inflammatory drugs (NSAID) are commonly used in sports medicine. NSAID have known anti-inflammatory, analgesic, antipyretic and antithrombotic effects, although their in-vivo effects in treating musculoskeletal injuries in humans remain largely unknown. NSAID analgesic action is not significantly greater than paracetamol for musculoskeletal injury but they have a higher risk profile, with side-effects including asthma exacerbation, gastrointestinal and renal side-effects, hypertension and other cardiovascular diseases. The authors recommend an approach to NSAID use in sports medicine whereby simple analgesia is preferentially used when analgesia is the primary desired outcome. However, based both on the current pathophysiological understanding of most injury presentations and the frequency that inflammation may actually be a component of the injury complex, it is premature to suppose that NSAID are not useful to the physician managing sports injuries. The prescribing of NSAID should be cautious and both situation and pathology specific. Both dose and duration minimisation should be prioritized and combined with simple principles of protection, rest, ice, compression, elevation (PRICE), which should allow NSAID-sparing. NSAID use should always be coupled with appropriate physical rehabilitation. NSAID are probably most useful for treating nerve and soft-tissue impingements, inflammatory arthropathies and tenosynovitis. They are not generally indicated for isolated chronic tendinopathy, or for fractures. The use of NSAID in treating muscle injury is controversial. Conditions in which NSAID use requires more careful assessment include ligament injury, joint injury, osteoarthritis, haematoma and postoperatively.

A position paper by the European Network for Drug Allergy (ENDA), the European Academy of Allergology and Clinical Immunology (EAACI) interest group on drug hypersensitivity, defines drug provocation tests (DPTs) as "the controlled administration of a drug in order to diagnose drug hypersensitivity reactions". The DPT is widely considered to be the "gold standard" to establish or exclude the diagnosis of hypersensitivity to a certain substance, as it not only reproduces hypersensitivity symptoms, but also any other adverse clinical manifestation, irrespective of the mechanism. The DPT can be harmful and thus should only be considered after balancing the risk-benefit ratio in the individual patient. The ENDA position paper specifies two main indications for DPTs with the suspected compounds: 1. to exclude hypersensitivity in non-suggestive histories of drug hypersensitivity and in patients with non-specific symptoms, such as vagal symptoms under local anesthesia; 2. to establish a firm diagnosis in suggestive histories of drug hypersensitivity with negative, non-conclusive, or non-available allergologic tests. A positive DPT result optimizes allergen avoidance, while a negative one allows a false label of drug hypersensitivity to be removed. For these reasons, DPTs are often carried out to exclude a diagnosis of hypersensitivity to beta-lactams when other allergologic tests are negative. DPTs are also performed when the sensitivity of allergologic tests for evaluating allergic reactions to certain drugs, such as non-beta-lactam antibiotics, heparins, and glucocorticoids, is limited. On the other hand, DPTs are also performed to diagnose hypersensitivity reactions to nonsteroidal anti-inflammatory drugs in subjects with the cross-reactive pattern, because both skin tests and in vitro diagnostic methods are ineffective in such patients.

Cross-sectional. To describe performance and asymmetry on the Star Excursion Balance Test (SEBT) by sex and sport, and to determine if differences exist within a collegiate athlete population. Performance on the SEBT may differ between sexes and levels of competition, though the results of previous studies have been inconsistent. Investigation of performance and asymmetry differences between sports is limited. Sex- and sport-specific reference values likely need to be determined to best assess SEBT performance. Performance on the SEBT was retrospectively reviewed in 393 healthy National Collegiate Athletic Association Division I collegiate athletes from 8 sports. Means, standard deviations, and 95% confidence intervals were calculated for all variables. Normalized reach distance (percent limb length) and asymmetry between limbs were compared for the anterior (ANT), posterolateral (PL), and posteromedial (PM) directions and for the composite (COMP) score using a 2-way analysis of variance (ANOVA) of sex by sport, and a 1-way ANOVA to separately compare sports within each sex. Average normalized reach distance ranged from 62% to 69%, 84% to 97%, and 99% to 113% in the ANT, PL, and PM directions, respectively, and from 82% to 92% in the COMP score. Normalized asymmetry ranged from 3% to 4%, 5% to 8%, and 5% to 6% in the ANT, PL, and PM directions, respectively. A significant sex-by-sport interaction (P = .039) was observed in the ANT direction, with a sex effect for soccer players (Psport.
Systematic comparison of δ13C measurements of testosterone and derivative steroids in a freeze-dried urine candidate reference material for sports drug testing by gas chromatography/combustion/isotope ratio mass spectrometry and uncertainty evaluation using four different metrological approaches.

An alternative calibration procedure for use when performing carbon isotope ratio measurements by gas chromatography/combustion/isotope ratio mass spectrometry (GC/C/IRMS) has been developed. This calibration procedure does not rely on the corrections in-built in the instrument software, as the carbon isotope ratios of a sample are calculated from the measured raw peak areas. The method was developed for the certification of a urine reference material for sports drug testing, as the estimation of measurement uncertainty is greatly simplified. To ensure that the method is free from bias arising from the choice of calibration material and instrument, the carbon isotope ratios of steroids in urine extracts were measured using two different instruments in different laboratories, and three different reference materials (CU/USADA steroid standards from Brenna Laboratory, Cornell University; NIST RM8539 mineral oil; methane calibrated against NIST RM8560 natural gas). The measurements were performed at LGC and the Australian National Measurement Institute (NMI). It was found that there was no significant difference in measurement results when different instruments and reference materials were used to measure the carbon isotope ratio of the major testosterone metabolites androsterone and etiocholanolone, or the endogenous reference compounds pregnanediol, 11- ketoetiocholanolone and 11β-hydroxyandrosterone. Expanded measurement uncertainties at the 95% coverage probability ranged from 0.21‰ to 1.4‰, depending on analyte, instrument and reference material. The measurement results of this comparison were used to estimate a measurement uncertainty of δ(13)C for the certification of the urine reference material being performed on a single instrument using a single reference material at NMI.

To conduct objective assessment of children with balance and vestibular complaints following sports-related concussions and identify the underlying deficits by analyzing laboratory test outcomes. Case series with chart review. Pediatric tertiary care facility. Medical records were reviewed of 42 pediatric patients with balance and/or vestibular complaints following sports-related concussions who underwent comprehensive laboratory testing on their balance and vestibular function. Patients' characteristics were summarized and results analyzed. More than 90% of the children with protracted dizziness or imbalance following sports-related concussion had at least 1 abnormal finding from the comprehensive balance and vestibular evaluation. The most frequent deficit was found in dynamic visual acuity test, followed by Sensory Organization Test and rotational test. Patient's balance problem associated with concussion seemed to be primarily instigated by vestibular dysfunction. Furthermore, semicircular canal dysfunction was involved more often than dysfunction of otolith organs. Yet, sports-related concussion. Vestibular impairment is common among children with protracted dizziness or imbalance following sports-related concussion. Our study demonstrated that proper and thorough evaluation is imperative to identify these underlying deficits and laboratory tests were helpful in the diagnosis and recommendation of following rehabilitations. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

Talent identification for future sport performance is of paramount interest for many groups given the challenges of finding and costs of training potential elite athletes. Because genetic factors have been implicated in many performance- related traits (strength, endurance, etc.), a natural inclination is to consider the addition of genetic testing to talent identification programs. While the importance of genetic factors to sport performance is generally not disputed, whether genetic testing can positively inform talent identification is less certain. The present paper addresses the science behind the genetic tests that are now commercially available (some under patent protection) and aimed at predicting future sport performance potential. Also discussed are the challenging ethical issues that emerge from the availability of these tests. The potential negative consequences associated with genetic testing of young athletes will very likely outweigh any positive benefit for sport performance prediction at least for the next several years. The paper ends by exploring the future possibilities for genetic testing as the science of genomics in sport matures over the coming decade(s).

Workplace drug testing (WDT) was established in Italy on 30 October 2007. Two tiers of survey are required: the first tier concerns drug testing on urine samples, the second involves both urine and hair analysis. Between July 2008 and December 2011, 10 598 workers' urine samples and 72 hair samples for opiates, cocaine, cannabinoids, amphetamines, methylenedioxyamphetamines, methadone, and buprenorphine were tested in our laboratory. Urine analyses were performed by immunological screening (EMIT); hair analysis and confirmation tests in urine were performed by gas chromatography-mass spectrometry (GC-MS). Employees tested positive in urine for drugs of abuse numbered 2.8% in 2008, 2.03% in 2009, 1.62% in 2010, and 1.43% in 2011. As regards the second level of analysis, we observed that only one-third of the workers who had been tested positive for drugs of abuse were referred to an Addiction Treatment Unit in order to verify drug addiction. Our experience shows that, four years after approval of the law on WDT, the percentage of workers positive for drugs of abuse in urine has reduced in comparison to the first year. Moreover, our data show that most of the times employees who tested positive are tardily referred or not referred at all to a Public Addiction Treatment Unit to verify drug addiction. This makes us believe that the legal provisions are widely disregarded not paying the right tribute to the fact that Italy is one of few European countries with legislation on WDT.

Full Text Available Workplace drug testing is less common in Norway than in many other countries. During the period from 2000-2006, 13469 urine or blood samples from employees in the offshore industry, shipping companies and aviation industry were submitted to the Norwegian Institute of Public Health for drug testing. The samples were analysed for benzodiazepines, illicit drugs, muscle relaxants with sedating properties, opioids and z-hypnotics. In total, 2.9% of the samples were positive for one or more substances. During the study period the prevalence decreased for morphine (from 1.9% to 1.1% and increased for amphetamine (from 0.04% to 0.6%, clonazepam (from 0% to 0.1%, methamphetamine (from 0.04% to 0.6%, nitrazepam (from 0% to 0.4% and oxazepam (from 0.5% to 1.3% (p<0.05. There was no significant change in prevalence for the other substances included in the analytical programme. Illicit drugs were significantly associated with lower age (OR: 0.93, p<0.05. This study found low prevalence of drugs among employees in companies with workplace drug testing programmes in Norway.

In response to concerns regarding substance abuse in the workplace, many employers are implementing Drug and Alcohol Testing programs. Various Provincial Human Rights Commissions and the Canadian Human Rights Commission have published position papers on some of the controversial testing policies. The Commissions generally do not support any testing except for reasonable cause and/or post accident testing. Other forms of testing may be acceptable in cases where a genuine occupational requirement can be established. Bill C-45 imposes a legal duty on both employees and employers to take reasonable measure to protect employees and enhance public safety. It was suggested that the industry could take guidance from recent court cases in Alberta, Quebec and British Columbia which have supported Drug and Alcohol Testing.

From an enactive approach to human activity, we suggest that the use of appearance-enhancing drugs is better explained by the sense-making related to body image rather than the cognitive evaluation of social norms about appearance and consequent psychopathology-oriented approach. After reviewing the main psychological disorders thought to link body image issues to the use of appearance-enhancing substances, we sketch a flexible, dynamic and embedded account of body image defined as the individual's propensity to act and experience in specific situations. We show how this enacted body image is a complex process of sense-making that people engage in when they are trying to adapt to specific situations. These adaptations of the enacted body image require effort, perseverance and time, and therefore any substance that accelerates this process appears to be an easy and attractive solution. In this enactive account of body image, we underline that the link between the enacted body image and substance use is also anchored in the history of the body's previous interactions with the world. This emerges during periods of upheaval and hardship, especially in a context where athletes experience weak participatory sense-making in a sport community. We conclude by suggesting prevention and intervention designs that would promote a safe instrumental use of the body in sports and psychological helping procedures for athletes experiencing difficulties with substances use and body image.

Since the late nineties, computerized neurocognitive testing has become a central component of sport-related concussion (SRC) management at all levels of sport. In 2005, a review of the available evidence on the psychometric properties of four computerized neuropsychological test batteries concluded that the tests did not possess the necessary criteria to warrant clinical application. Since the publication of that review, several more computerized neurocognitive tests have entered the market place. The purpose of this review is to summarize the body of published studies on psychometric properties and clinical utility of computerized neurocognitive tests available for use in the assessment of SRC. A review of the literature from 2005 to 2013 was conducted to gather evidence of test-retest reliability and clinical validity of these instruments. Reviewed articles included both prospective and retrospective studies of primarily sport-based adult and pediatric samples. Summaries are provided regarding the available evidence of reliability and validity for the most commonly used computerized neurocognitive tests in sports settings.

This paper addresses practical and ethical considerations regarding genetic tests to predict performance and/or risk of exercise-related injury or illness. Various people might wish to conduct sport-related genetic tests for a variety of reasons. For example, an individual might seek personal genetic information to help guide their own sport participation. A sports coach might wish to test young athletes to aid team selection or individualize training. A physician might want to predict the risk of injury or illness in athletes and advise regarding selection or preventative measures. An insurance company might seek to estimate the risk of career-threatening injury for athletes based partly on genetic information. Whilst this information is, in part, encoded in our DNA sequence, the available tests allow generally only a poor prediction of the aforementioned variables. In other words, the current genetic tests and analysis methods are not powerful enough to inform important decisions in sport to a substantial degree. It is particularly disappointing that more than half of the commercially available genetic tests related to exercise and sport do not appear to identify publicly the genetic variants they assess, making scrutiny by academic scholars and consumers (or their representatives) impossible. There are also challenging ethical issues to consider. For example, the imposition of genetic tests on individuals (especially young people) by third parties is potentially susceptible to abuse. Scientists and practitioners should understand the limitations of the tests currently available, the ethical concerns and the importance of counselling before and after testing so that they are only used in a responsible manner. © 2016 S.

The present study assessed the application of a multidimensional model of motivation and engagement (the Motivation and Engagement Wheel) and its accompanying instrumentation (the Motivation and Engagement Scale) to the music and sport domains. Participants were 463 young classical musicians (N=224) and sportspeople (N=239). In both music and sport samples, the data confirmed the good fit of the four hypothesized higher-order dimensions and their 11 first-order dimensions: adaptive cognitions (self-efficacy, valuing, mastery orientation), adaptive behaviors (planning, task management, persistence), impeding/maladaptive cognitions (uncertain control, anxiety, failure avoidance), and maladaptive behaviors (self-handicapping, disengagement). Multigroup tests of factor invariance showed that in terms of underlying motivational constructs and the composition of and relationships among these constructs, key subsamples are not substantially different. Moreover-and of particular relevance to issues around the generalizability of the framework-the factor structure for music and sport samples was predominantly invariant.

This case report describes the development, implementation, and outcomes of a fitness-related intervention program that addressed the sport-specific goals of an adolescent with cerebral palsy. The participant in this case was a 16-year-old African American male with spastic diplegia. The participant joined his high school wrestling team and asked to focus his physical therapy on interventions that would improve his wrestling performance. An examination was performed using the muscle power sprint test, the 10 x 5-m sprint test, strength tests, the 10-m shuttle run test, and the Gross Motor Function Measure. The intervention consisted of interval training, which focused on the demands of wrestling. Scores on all tests and measures were higher after the intervention. The outcomes of this case report seem to support the use of a fitness-related intervention program for addressing the sport-specific goals of an adolescent with cerebral palsy.

Drug testing with the use of point of care testing (POCT) has been widely used in Japan, especially in the field of drug abuse, poisoning, and anticoagulant therapy with warfarin. For evidence-based medicine of POCT, an interesting report was presented by the National Academy of Clinical Biochemistry in the United States as the guideline in 2006. Users of POCT devices should understand all limitations of the devices. This strength/consensus recommendation is strong and the level of evidence is high. In this field, cyan, arsenic, paraquat, organic phosphate, methanol, acetaminophen, barbiturates, benzodiazepines, antidepressants, and some other drugs were detected by POCT devices such as Triage DOA and a detector tube system and others in Japan. The usefulness of the organophosphorus pesticide detection kit in the accident of GYOZA POISONING from china was noteworthy. In the case of toluene intoxication, the detector tube system was useful as a screening test for the gas phase test of a 2-year-old patient's vomit and excreta without any information from his parents. In warfarin treatment, a POCT device was useful for small hospitals and clinics. Although the cost is not covered by the health insurance system in Japan, the emergency centers of hospitals use these POCT devices for clinical decision-making. This is the most important problem.

Exercise testing is an important tool for determining baseline fitness as well as to diagnose limitations in performance. The Bruce protocol has become the standard for exercise testing protocol in many exercise physiology laboratories, but is rarely a suitable test for athletes who often have complex hemodynamic and metabolic demands during exercise required for practice and competition. We describe the approach for exercise testing beyond the Bruce protocol and focus on strategies to individualize the testing protocol to the metabolic demands of an athlete's sport.

This report provides information about drug testing by American secondary schools, based on results from national surveys. The study provides descriptive information on drug-testing practices by schools from 1998 to 2001, and examines the association between drug testing by schools and reported drug use by students. School-level data on drug testing were obtained through the Youth, Education, and Society study, and student-level survey data were obtained from the same schools participating in the Monitoring the Future study. A relatively small percentage of schools (about 18%) reported testing students for drug use, with more high schools than middle schools reporting drug testing. Drug testing was not associated with students' reported illicit drug use, or with rate of use among experienced marijuana users. Drug testing of athletes was not associated with illicit drug use among male high school athletes. Policy implications are discussed.

In 2012, Duke University initiated a research project, funded by an unrestricted research grant from Millennium Laboratories, a drug testing company. The project focused on assessing the frequency and nature of questionable, unethical, and illegal business practices in the clinical drug testing industry and assessing the potential for establishing a business code of ethics. Laboratory leaders, clinicians, industry attorneys, ethicists, and consultants participated in the survey, were interviewed, and attended two face-to-face meetings to discuss a way forward. The study demonstrated broad acknowledgment of variations in the legal and regulatory environment, resulting in inconsistent enforcement of industry practices. Study participants expressed agreement that overtly illegal practices sometimes exist, particularly when laboratory representatives and clinicians discuss reimbursement, extent of testing, and potential business incentives with medical practitioners. Most respondents reported directly observing probable violations involving marketing materials, contracts, or, in the case of some individuals, directly soliciting people with offers of clinical supplies and other "freebies." While many study respondents were skeptical that voluntary standards alone would eliminate questionable business practices, most viewed ethics codes and credentialing as an important first step that could potentially mitigate uneven enforcement, while improving quality of care and facilitating preferred payment options for credentialed parties. Many were willing to participate in future discussions and industry-wide initiatives to improve the environment.

Although sport for athletes with mental retardation (MR) is achieving an important role, literature concerning basketball test and training is still poor. The aims of this study were to assess basketball ability before (PRE) and after (POST) a 6-month training in athletes with MR across 2 sports seasons (ss) and to analyze the variation of basketball abilities by subjects' MR level. Fifteen trained basketball players with MR participated (11 men and 4 women; age range 19-43 years; MR: 3 Mild, 8 Moderate, 3 Severe, and 1 Profound). Athletes were tested PRE and POST a 6-month training during 2 following sports seasons (ss1 and ss2). The tests assessed 4 ability levels, each one characterized by the analysis of 4 fundamental areas (ball handling, reception, passing, and shooting), divided into 5 specific components. The athletes' global score improved after training in both ss1 (41.5 +/- 12.0 vs. 48.6 +/- 15.4; p training caused a general improvement, especially evident in levels II and III in both ss. Global and level scores were negatively correlated to MR level (p training.

There is consensus that children have questionable decisional capacity and, therefore, in general a parent or a guardian must give permission to enroll a child in a research study. Moreover, freedom from duress and coercion, the cardinal rule in research involving adults, is even more important for children. This principle is embodied prominently in the Nuremberg Code (1947) and is embodied in various federal human research protection regulations. In a program named "SATURN" (Student Athletic Testing Using Random Notification), each school in the Oregon public-school system may implement a mandatory drug-testing program for high school student athletes. A prospective study to identify drug use among student-athletes, SATURN is designed both to evaluate the influence of random drug testing and to validate the survey data through identification of individuals who do not report drug use. The enrollment of students in the drug-testing study is a requirement for playing a school sport. In addition to the coercive nature of this study design, there were ethically questionable practices in recruitment, informed consent, and confidentiality. This article concerns the question of whether research can be conducted with high school students in conjunction with a mandatory drug-testing program, while adhering to prevailing ethical standards regarding human-subjects research and specifically the participation of children in research.

Assessment of the functional capacity of the cardiovascular system is essential in sports medicine. For athletes, the maximal oxygen uptake [Formula: see text] provides valuable information about their aerobic power. In the clinical setting, the (VO(2max)) provides important diagnostic and prognostic information in several clinical populations, such as patients with coronary artery disease or heart failure. Likewise, VO(2max) assessment can be very important to evaluate fitness in asymptomatic adults. Although direct determination of [VO(2max) is the most accurate method, it requires a maximal level of exertion, which brings a higher risk of adverse events in individuals with an intermediate to high risk of cardiovascular problems. Estimation of VO(2max) during submaximal exercise testing can offer a precious alternative. Over the past decades, many protocols have been developed for this purpose. The present review gives an overview of these submaximal protocols and aims to facilitate appropriate test selection in sports, clinical, and home settings. Several factors must be considered when selecting a protocol: (i) The population being tested and its specific needs in terms of safety, supervision, and accuracy and repeatability of the VO(2max) estimation. (ii) The parameters upon which the prediction is based (e.g. heart rate, power output, rating of perceived exertion [RPE]), as well as the need for additional clinically relevant parameters (e.g. blood pressure, ECG). (iii) The appropriate test modality that should meet the above-mentioned requirements should also be in line with the functional mobility of the target population, and depends on the available equipment. In the sports setting, high repeatability is crucial to track training-induced seasonal changes. In the clinical setting, special attention must be paid to the test modality, because multiple physiological parameters often need to be measured during test execution. When estimating VO(2max), one has

To examine the validity and reliability of a sports-specific endurance plank test for the evaluation of global core muscle function. Repeated-measures study. Laboratory environment. Twenty-eight male and eight female young athletes. Surface electromyography (sEMG) of selected trunk flexors and extensors, and an intervention of pre-fatigue core workout were applied for test validation. Intraclass correlation coefficient (ICC), coefficient of variation (CV), and the measurement bias ratio */÷ ratio limits of agreement (LOA) were calculated to assess reliability and measurement error. Test validity was shown by the sEMG of selected core muscles, which indicated >50% increase in muscle activation during the test; and the definite discrimination of the ∼30% reduction in global core muscle endurance subsequent to a pre-fatigue core workout. For test-retest reliability, when the first attempt of three repeated trials was considered as familiarisation, the ICC was 0.99 (95% CI: 0.98-0.99), CV was 2.0 ± 1.56% and the measurement bias ratio */÷ ratio LOA was 0.99 */÷ 1.07. The findings suggest that the sport-specific endurance plank test is a valid, reliable and practical method for assessing global core muscle endurance in athletes given that at least one familiarisation trial takes place prior to measurement.

Full Text Available Children aged 4 and 5 have great motor potential. Testing certain motor skills and measuring morphological characteristics are important steps in examining sport development of children. The subject of this paper is assessing motor skills and measuring morphological characteristics of students of sport school Sportomanija in Belgrade. The sample was made up of 16 male examinees aged 4 and 5. The battery of motor tests was composed of the following : deep reach (standing position, standing long jump, 20 metres running, 4x5 metres running, lying into sitting position in 20 seconds. Statistical analysis of results meant correlating results of motor tests and anthropometric measurment. The results show a statistically relevant negative correlation between body mass index (BMI and long jump results (r=-0,55, p<0,05. On the other hand, there is a high positive correlation (over r=0,70, p<0,05 between the results of motor tests: standing long jump, 20 metres running, 4x5 metres running, lying-sit in 20 seconds. These resultes are in the accordance with the similarity in the ways muscle strength is manifested under different conditions. Considering the correlation between these results provides the basis for testing the nature of this conection. Examining the connection between the anthropometric and motor scope during a targeted influence on a child’s body in sport school Sportomanija allows for gaining insight into some of the characteristics of the examinee’s age. Acquaitance with examinee’s model characteristics as well as structure of motor skills and longterm examining of anthropometric and motor scope are the basis of plan and action of the experts working with children and the young.

After more than 2 yr of operation of a drug testing program at the San Onofre nuclear power plant site, the Southern California Edison Co. has had a number of experiences and lessons considered valuable. The drug testing program at San Onofre, implemented in September of 1984, continues in essentially the same form today. Prior to describing the program, the paper reviews several underlying issues that believed to be simultaneously satisfied by the program: trustworthiness, fitness and safety, public trust, and privacy and search. The overall drug testing program, periodic drug monitoring program, and unannounced drug testing program are described. In addition to the obvious features of a good drug testing program, which are described in the EEI guide, it is essential to consider such issues as the stated program rationale, employee relations, and disciplinary action measures when contemplating or engaging in drug testing at nuclear power plants

Testing for drugs in biologic fluids, especially urine, is a practice that has become widespread. The technology of testing for drugs in urine has greatly improved in recent years. Inexpensive screening techniques are not sufficiently accurate for forensic testing standards, which must be met wihen a person's employment or reputation may be affected by results. This is particularly a concern during screening of a population in which the prevalence of drug use is very low, in which the predictive value of a positive result would be quite low. Physicians should be aware that results from drug testing can yield accurate evidence of prior exposure to drugs, but they do not provide information about patterns of drug use, about abuse of or dependence on drugs, or about mental or physical impairments that may result from drug use

Mild traumatic brain injuries (MTBI) or concussions often result in problems with attention, executive functions, and motor control. For better identification of these diverse problems, novel approaches integrating tests of cognitive and motor functioning are needed. The aim was to characterize minor changes in motor and cognitive performance after sports-related concussions with a novel test battery, including balance tests and a computerized multilimb reaction time test. The cognitive demands of the battery gradually increase from a simple stimulus response to a complex task requiring executive attention. A total of 113 male ice hockey players (mean age = 24.6 years, SD = 5.7) were assessed before a season. During the season, nine concussed players were retested within 36 hours, four to six days after the concussion, and after the season. A control group of seven nonconcussed players from the same pool of players with comparable demographics were retested after the season. Performance was measured using a balance test and the Motor Cognitive Test battery (MotCoTe) with multilimb responses in simple reaction, choice reaction, inhibition, and conflict resolution conditions. The performance of the concussed group declined at the postconcussion assessment compared to both the baseline measurement and the nonconcussed controls. Significant changes were observed in the concussed group for the multilimb choice reaction and inhibition tests. Tapping and balance showed a similar trend, but no statistically significant difference in performance. In sports-related concussions, complex motor tests can be valuable additions in assessing the outcome and recovery. In the current study, using subtasks with varying cognitive demands, it was shown that while simple motor performance was largely unaffected, the more complex tasks induced impaired reaction times for the concussed subjects. The increased reaction times may reflect the disruption of complex and integrative cognitive

In recent decades, urine drug testing in the workplace has become common in many countries in the world. There have been several studies concerning the use of the urine specimen validity test (SVT) for drug abuse testing administered in the workplace. However, very little data exists concerning the urine SVT on drug abuse tests from court specimens, including dilute, substituted, adulterated, and invalid tests. We investigated 21,696 submitted urine drug test samples for SVT from workplace an...

This study evaluated the test-retest reliability of a novel computer-based, portable balance assessment tool, the Equilibrate System (ES), used to diagnose sports-related concussion. Twenty-seven students participated in ES testing consisting of three sessions over 4 weeks. The modified Balance Error Scoring System was performed. For each participant, test-retest reliability was established using the intraclass correlation coefficient (ICC). The ES test-retest reliability from baseline to week 2 produced an ICC value of 0.495 (95% CI, 0.123-0.745). Week 2 testing produced ICC values of 0.602 (95% CI, 0.279-0.803) and 0.610 (95% CI, 0.299-0.804), respectively. All other single measures test-retest reliability values produced poor ICC values. Same-day ES testing showed fair to good test-retest reliability while interweek measures displayed poor to fair test-retest reliability. Testing conditions should be controlled when using computerized balance assessment methods. ES testing should only be used as a part of a comprehensive assessment.

One of the fundamental challenges in anti-doping is identifying athletes who use, or are at risk of using, prohibited performance enhancing substances. The growing trend to employ a forensic approach to doping control aims to integrate information from social sciences (e.g., psychology of doping) into organised intelligence to protect clean sport. Beyond the foreseeable consequences of a positive identification as a doping user, this task is further complicated by the discrepancy between what constitutes a doping offence in the World Anti-Doping Code and operationalized in doping research. Whilst psychology plays an important role in developing our understanding of doping behaviour in order to inform intervention and prevention, its contribution to the array of doping diagnostic tools is still in its infancy. In both research and forensic settings, we must acknowledge that (1) socially desirable responding confounds self-reported psychometric test results and (2) that the cognitive complexity surrounding test performance means that the response-time based measures and the lie detector tests for revealing concealed life-events (e.g., doping use) are prone to produce false or non-interpretable outcomes in field settings. Differences in social-cognitive characteristics of doping behaviour that are tested at group level (doping users vs. non-users) cannot be extrapolated to individuals; nor these psychometric measures used for individual diagnostics. In this paper, we present a position statement calling for policy guidance on appropriate use of psychometric assessments in the pursuit of clean sport. We argue that, to date, both self-reported and response-time based psychometric tests for doping have been designed, tested and validated to explore how athletes feel and think about doping in order to develop a better understanding of doping behaviour, not to establish evidence for doping. A false 'positive' psychological profile for doping affects not only the individual

Drug testing in the workplace has gone from virtual nonexistence to widespread employer acceptance during the past two decades. This growth is particularly significant for the construction industry. High rates of alcohol and other drug use, coupled with the high-risk, safety-sensitive nature of the industry, have prompted the development of a variety of drug surveillance and prevention strategies. Despite this growing vigilance, no scholarly works have examined the impact of drug-related policies in the construction industry. To address this limitation, we investigate the efficacy of workplace drug-testing programs in reducing injury incident rates and workers' compensation experience-rating modification factors (MODs) within the construction industry. Analyses indicate that companies with drug-testing programs experienced a 51 percent reduction in incident rates within two years of implementation. Moreover, companies that drug test their employees experienced a significant reduction in their MODs. Policy implications are discussed in light of the current findings.

There have been increasing national and international calls for the introduction of drug testing as a policy measure to address harmful drug use. Such strategies have been applied in workplaces, sporting arenas, prisons and more latterly school settings. They are predicated on a belief in their efficacy in reducing drug-related harm, a need to 'send the right' message to potential users and to reassure the community at large that 'something is being done.' Rigorous examination is required of purported benefits of drug testing in schools. A comprehensive examination was made of testing efficacy and accuracy. Australian legal and ethical issues, encompassing duty of care, rights of the child and privacy determinations, were juxtaposed with that of the United States of America. Evidence examined indicates no compelling case for the application of drug testing and that caution should be applied when considering drug testing as a drug detection and prevention strategy in the school setting. While this review did not support school drug testing, there are alternative evidence-based strategies that schools can implement to prevent drug-related problems among student populations.

Drug testing is often used as part of an assessment for substance use in children and adolescents. However, the indications for drug testing and guidance on how to use this procedure effectively are not clear. The complexity and invasiveness of the procedure and limitations to the information derived from drug testing all affect its utility. The objective of this clinical report is to provide guidance to pediatricians and other clinicians on the efficacy and efficient use of drug testing on the basis of a review of the nascent scientific literature, policy guidelines, and published clinical recommendations.

Computerized neuropsychological tests are frequently used to assist in return-to-play decisions following sports concussion. However, due to concerns about test reliability, the Centers for Disease Control and Prevention recommends yearly baseline testing. The standard practice that has developed in baseline/postinjury comparisons is to examine the difference between the most recent baseline test and postconcussion performance. Drawing from classical test theory, the present study investigated whether temporal stability could be improved by taking an alternate approach that uses the aggregate of 2 baselines to more accurately estimate baseline cognitive ability. One hundred fifteen English-speaking professional hockey players with 3 consecutive Immediate Postconcussion Assessment and Testing (ImPACT) baseline tests were extracted from a clinical program evaluation database overseen by the National Hockey League and National Hockey League Players' Association. The temporal stability of ImPACT composite scores was significantly increased by aggregating test performance during Sessions 1 and 2 to predict performance during Session 3. Using this approach, the 2-factor Memory (r = .72) and Speed (r = .79) composites of ImPACT showed acceptable long-term reliability. Using the aggregate of 2 baseline scores significantly improves temporal stability and allows for more accurate predictions of cognitive change following concussion. Clinicians are encouraged to estimate baseline abilities by taking into account all of an athlete's previous baseline scores.
Full Text Available Sport-specific motor fitness tests are not often examined in water polo. In this study we examined the reliability, factorial and discriminative validity of 10 water-polo-specific motor-fitness tests, namely: three tests of in-water jumps (thrusts, two characteristic swimming sprints (10 and 20 metres from the water start, three ball-throws (shoots, one test of passing precision (accuracy, and a test of the dynamometric force produced while using the eggbeater kick. The sample of subjects consisted of 54 young male water polo players (15 to 17 years of age; 1.86 ± 0.07 m, and 83.1 ± 9.9 kg. All tests were applied over three testing trials. Reliability analyses included Cronbach Alpha coefficients (CA, inter-item- correlations (IIR and coefficients of the variation (CV, while an analysis of variance was used to define any systematic bias between the testing trials. All tests except the test of accuracy (precision were found to be reliable (CA ranged from 0.83 to 0.97; IIR from 0.62 to 0.91; CV from 2% to 21%; with small and irregular biases between the testing trials. Factor analysis revealed that jumping capacities as well as throwing and sprinting capacities should be observed as a relatively independent latent dimensions among young water polo players. Discriminative validity of the applied tests is partially proven since the playing positions significantly (p < 0.05 differed in some of the applied tests, with the points being superior in their fitness capacities in comparison to their teammates. This study included players from one of the world’s best junior National leagues, and reported values could be used as fitness standards for such an age. Further studies are needed to examine the applicability of the proposed test procedures to older subjects and females.

In this study, we tested some key postulates of Eysenck and Calvo's processing efficiency theory in a team sport. The participants were 12 elite male volleyball players who were followed throughout the course of a competitive season. Self-report measures of pre-match and in-game cognitive anxiety and mental effort were collected in groups of players high and low in dispositional anxiety. Player performance was determined from the statistical analysis of match-play. Sets were classified according to the point spread separating the two teams into one of three levels of criticality. Game momentum was also analysed to determine its influence on in-game state anxiety. Significant differences in in-game cognitive anxiety were apparent between high and low trait anxiety groups. An interaction between anxiety grouping and momentum condition was also evident in cognitive anxiety. Differences in set criticality were reflected in significant elevations in mental effort, an effect more pronounced in dispositionally high anxious performers. Consistent with the predictions of processing efficiency theory, mental effort ratings were higher in high trait-anxious players in settings where their performance was equivalent to that of low trait-anxious performers. The usefulness of processing efficiency theory as an explanatory framework in sport anxiety research is discussed in the light of these findings.

To compare a novel sprint test on a cycle ergometer with a countermovement-jump (CMJ) test for monitoring neuromuscular fatigue after Australian rules football match play. Twelve elite under-18 Australian rules football players (mean ± SD age 17.5 ± 0.6 y, stature 184.7 ± 8.8 cm, body mass 75.3 ± 7.8 kg) from an Australian Football League club's Academy program performed a short sprint test on a cycle ergometer along with a single CMJ test 1 h prematch and 1, 24, and 48 h postmatch. The cycle-ergometer sprint test involved a standardized warm-up, a maximal 6-s sprint, a 1-min active recovery, and a 2nd maximal 6-s sprint, with the highest power output of the 2 sprints recorded as peak power (PP). There were small to moderate differences between postmatch changes in cycle-ergometer PP and CMJ PP at 1 (ES = 0.49), 24 (ES = -0.85), and 48 h postmatch (ES = 0.44). There was a substantial reduction in cycle-ergometer PP at 24 h postmatch (ES = -0.40) compared with 1 h prematch. The cycle-ergometer sprint test described in this study offers a novel method of neuromuscular-fatigue monitoring in team-sport athletes and specifically quantifies the concentric component of the fatigue-induced decrement of force production in muscle, which may be overlooked by a CMJ test.

Three stages of the pathogenic mechanism of drug allergies can be considered: antigen formation, immune reaction and inflammation/disorder reaction. Drugs are thought to form 4 types of antigens: drug only, polymers, drug-carrier conjugates, and metabolite-carrier complexes. Antigens are recognized by B cell receptors and T cell receptors. Helper T cells (Th) are differentiated into four subsets, namely, Th1, Th2, Th17 and regulatory T cells (Treg). Th1 produces interleukin (IL)-2 and interferon (IFN)-γ, and activates macrophages and cytotoxic T cells (Tc). Macrophages induce type IV allergies, and Tc lead to serious type IV allergies. On the other hand, Th2 produces IL-4, IL-5, and IL-6, etc., and activates B cells. B cells produce IgE antibodies, and the IgE antibody affects mast cells and induces type I allergies. Activated eosinophil leads to the chronic state of type I allergy. Diagnostic testing for allergenic drugs is necessary for patients with drug allergies. Because in vivo diagnostic tests for allergenic drugs are associated with a risk and burden to the patient, in vitro allergy tests are recommended to identify allergenic drugs. In allergy tests performed in vitro, cytological tests are more effective than serological tests, and the leukocyte migration test (LMT) presently has the highest efficacy. An LMT-chamber is better than LMT-agarose in terms of usability and sensitivity, and it can detect about 80% of allergenic drugs.

Immunogenicity testing is required for safety assessment of biotherapeutic drugs. Because levels observed during biotherapeutic administration can approach the mg/ml range, establishing drug tolerance is significantly important for assay development. Three assay formats for immunogenicity assessment were tested with respect to drug tolerance: Meso Scale Discovery(®) bridging (MSDB), solid-phase extraction with acid dissociation (SPEAD) and affinity capture elution (ACE). Six biotherapeutic drugs were analyzed by the three methods; four monoclonal antibodies, one Fc fusion protein and one Pegylated protein. Overall, ACE performed best for assays involving therapeutic monoclonal antibodies and also functioned well for therapeutic proteins. Despite several advantages, the MSDB assays displayed a potentially significant hook effect. SPEAD was comparable in performance to ACE for the biotherapeutic drugs tested, but suffers the disadvantage of being reagent-intensive. Novel assay formats offer significant advantages for immunogenicity testing, particularly in the design of assays that are tolerant to circulating levels of the biotherapeutic drug.

Thailand has relied on drug law enforcement in an effort to curb illicit drug use. While anecdotal reports suggest that Thai police frequently use urine toxicology to identify drug users, little is known about the prevalence or impacts of this practice among people who inject drugs (IDU). Therefore, we sought to examine experiences with urine drug testing by police among IDU in Bangkok. Data were derived from a community-recruited sample of IDU in Bangkok participating in the Mitsampan Community Research Project between July and October 2011. We assessed the prevalence and correlates of being subjected to urine toxicology testing by police using multivariate Poisson regression. In total, 438 IDU participated in this study, with 293 (66.9%) participants reporting having been tested for illicit drugs by police. In multivariate analyses, reports of drug testing by police were independently and positively associated with younger age (adjusted prevalence ratio [APR]: 1.28), a history of methamphetamine injection (APR: 1.22), a history of incarceration (APR: 1.21), having been in compulsory drug detention (APR: 1.43), avoiding healthcare (APR: 1.15), and HIV seropositivity (APR: 1.19), and negatively associated with access to voluntary drug treatment (APR: 0.82) (all p<0.05). A high proportion of IDU in Bangkok were subjected to drug testing by police. Young people and methamphetamine injectors were more likely to have been tested. The findings indicate that drug testing by police is associated with the compulsory drug detention system and may be interfering with IDU's access to healthcare and voluntary drug treatment. These findings raise concern about the widespread practice of drug testing by police and its associated impacts. Copyright © 2013 Elsevier B.V. All rights reserved.

We estimated the proportion of the nation's public school districts that have high school grades in which random drug testing is conducted. We collected data in spring 2005 from 1343 drug prevention coordinators in a nationally representative sample of school districts with schools that have high school grades; of these districts, 14% conducted random drug testing. Almost all districts randomly tested athletes, and 65% randomly tested other students engaged in extracurricular activities; 28% randomly tested all students, exceeding the current sanction of the US Supreme Court.

The general consensus among sport and exercise genetics researchers is that genetic tests have no role to play in talent identification or the individualised prescription of training to maximise performance. Despite the lack of evidence, recent years have witnessed the rise of an emerging market of direct-to-consumer marketing (DTC) tests that claim to be able to identify children's athletic talents. Targeted consumers include mainly coaches and parents. There is concern among the scientific community that the current level of knowledge is being misrepresented for commercial purposes. There remains a lack of universally accepted guidelines and legislation for DTC testing in relation to all forms of genetic testing and not just for talent identification. There is concern over the lack of clarity of information over which specific genes or variants are being tested and the almost universal lack of appropriate genetic counselling for the interpretation of the genetic data to consumers. Furthermore independent studies have identified issues relating to quality control by DTC laboratories with different results being reported from samples from the same individual. Consequently, in the current state of knowledge, no child or young athlete should be exposed to DTC genetic testing to define or alter training or for talent identification aimed at selecting gifted children or adolescents. Large scale collaborative projects, may help to develop a stronger scientific foundation on these issues in the future. PMID:26582191

Appropriate dietary intake can have a significant influence on athletic performance. There is a growing consensus on sports nutrition and professionals working with athletes often provide dietary education. However, due to the limitations of existing sports nutrition knowledge questionnaires, previous reports of athletes' nutrition knowledge may be inaccurate. An updated questionnaire has been developed based on a recent review of sports nutrition guidelines. The tool has been validated using a robust methodology that incorporates relevant techniques from classical test theory (CTT) and Item response theory (IRT), namely, Rasch analysis. The final questionnaire has 89 questions and six sub-sections (weight management, macronutrients, micronutrients, sports nutrition, supplements, and alcohol). The content and face validity of the tool have been confirmed based on feedback from expert sports dietitians and university sports students, respectively. The internal reliability of the questionnaire as a whole is high (KR = 0.88), and most sub-sections achieved an acceptable internal reliability. Construct validity has been confirmed, with an independent T-test revealing a significant ( p < 0.001) difference in knowledge scores of nutrition (64 ± 16%) and non-nutrition students (51 ± 19%). Test-retest reliability has been assured, with a strong correlation ( r = 0.92, p < 0.001) between individuals' scores on two attempts of the test, 10 days to 2 weeks apart. Three of the sub-sections fit the Rasch Unidimensional Model. The final version of the questionnaire represents a significant improvement over previous tools. Each nutrition sub-section is unidimensional, and therefore researchers and practitioners can use these individually, as required. Use of the questionnaire will allow researchers to draw conclusions about the effectiveness of nutrition education programs, and differences in knowledge across athletes of varying ages, genders, and athletic

Diurnal variations in wastewater flows are common phenomena related to peak water use periods. However, few studies have examined high-resolution temporal variability in trace organic contaminant (TOrC) concentrations and loadings. Even fewer have assessed the impacts of a special event or holiday. This study characterizes the temporal variability associated with a major sporting event using flow data and corresponding mass loadings of a suite of prescription pharmaceuticals, potential endocrine disrupting compounds (EDCs), and illicit drugs. Wastewater influent and finished effluent samples were collected during the National Football League's Super Bowl, which is a significant weekend for tourism in the study area. Data from a baseline weekend is also provided to illustrate flows and TOrC loadings during "normal" operational conditions. Some compounds exhibited interesting temporal variations (e.g., atenolol), and several compounds demonstrated different loading profiles during the Super Bowl and baseline weekends (e.g., the primary cocaine metabolite benzoylecgonine). Interestingly, the influent mass loadings of prescription pharmaceuticals were generally similar in magnitude to those of the illicit drugs and their metabolites. However, conventional wastewater treatment was more effective in removing the illicit drugs and their metabolites. Total influent and effluent mass loadings are also provided to summarize treatment efficacy and environmental discharges. Copyright © 2011 Elsevier Ltd. All rights reserved.

Diuretics are drugs that increase the rate of urine flow and sodium excretion to adjust the volume and composition of body fluids. There are several major categories of this drug class and the compounds vary greatly in structure, physicochemical properties, effects on urinary composition and renal haemodynamics, and site and mechanism of action. Diuretics are often abused by athletes to excrete water for rapid weight loss and to mask the presence of other banned substances. Because of their abuse by athletes, diuretics have been included on The World Anti-Doping Agency's (WADA) list of prohibited substances; the use of diuretics is banned both in competition and out of competition and diuretics are routinely screened for by anti-doping laboratories. This review provides an overview of the pharmacology and toxicology of diuretics and discusses their application in sports. The most common analytical strategies currently followed by the anti-doping laboratories accredited by the WADA are discussed along with the challenges laboratories face for the analysis of this diverse class of drugs.

Adolescent drug and alcohol use is a major public health problem. Multiple studies indicate that substance use is a risk factor for physical and mental disorders in adolescents. Secondary schools and the communities they serve have been facing a long-standing problem of substance abuse. American adolescents have become quite accustomed to drug prevention being a part of their curriculum. However, some policy decisions made by school administrators have been legally challenged. In 1989, Vernonia School District serving a small community in Oregon, instituted a random drug testing policy of its athletes. In 1991, the parents of a seventh grader refused to give their consent for random drug testing. The seventh grader was denied participation in the sport and sued the School District arguing that the school policy violated the Fourth and Fourteenth Amendments to the United States Constitution, and Article I, Section 9 of the Oregon Constitution. In 1995, on appeal to the Supreme Court of the United States, the School District won the case. The Vernonia School District versus Acton case became a landmark case, but random drug and alcohol testing in secondary schools has been a subject of multiple court cases. The authors discuss three of them. Both Federal and State Courts have recognized that a secondary school environment in itself represents "a special need," for which suspicionless searches are sometimes necessary to maintain order, safety, and discipline. Drug and alcohol testing programs in secondary schools may still be challenged on its legality. Therefore, examining court sanctioned programs and their long-term efficacy statistics is recommended.

To review the diagnostic tests and investigations used in the management of sports concussion, in the adult and paediatric populations, to (a) monitor the severity of symptoms and deficits, (b) track recovery and (c) advance knowledge relating to the natural history and neurobiology of the injury. Qualitative literature review of the neuroimaging, balance testing, electrophysiology, blood marker and concussion literature. PubMed and Medline databases were reviewed for investigations used in the management of adult and paediatric concussion, including structural imaging (computerised tomography, magnetic resonance imaging, diffusion tensor imaging), functional imaging (single photon emission computerised tomography, positron emission tomography, functional magnetic resonance imaging), spectroscopy (magnetic resonance spectroscopy, near infrared spectroscopy), balance testing (Balance Error Scoring System, Sensory Organization Test, gait testing, virtual reality), electrophysiological tests (electroencephalography, evoked potentials, event related potentials, magnetoencephalography, heart rate variability), genetics (apolipoprotein E4, channelopathies) and blood markers (S100, neuron-specific enolase, cleaved Tau protein, glutamate). For the adult and paediatric populations, each test has been classified as being: (1) clinically useful, (2) a research tool only or (3) not useful in sports-related concussion. The current status of the diagnostic tests and investigations is analysed, and potential directions for future research are provided. Currently, all tests and investigations, with the exception of clinical balance testing, remain experimental. There is accumulating research, however, that shows promise for the future clinical application of functional magnetic resonance imaging in sport concussion assessment and management.

This paper explores the question of whether school drug testing is an effective solution to tackle adolescent substance abuse problems. Research studies in major academic databases and Internet websites are reviewed. Several observations are highlighted from the review: (1) there are few research studies in this area, particularly in different Chinese contexts; (2) the quality of the existing studies was generally low; and (3) research findings supporting the effectiveness of school drug testing were mixed. Methodological issues underlying quantitative and qualitative evaluation studies of the effectiveness of school drug testing are also discussed.

These European Guidelines for Workplace Drug Testing in Urine have been prepared and updated by the European Workplace Drug Testing Society (EWDTS). The first version of these urine guidelines was published in 2002. Since then, the guidelines have been followed by many laboratories in different European countries and their role has been essential particularly in countries lacking legislation for workplace drug testing. In 2014, the EWDTS started a guidelines updating project and published a new version of the urine guidelines in 2015. Here we represent this updated version of the urine guidelines. The European Guidelines are designed to establish best practice procedures whilst allowing individual countries to operate within the requirements of national customs and legislation. The EWDTS recommends that all European laboratories that undertake legally defensible workplace drug testing should use these guidelines as a template for accreditation.

The management of sports-related concussions (SRCs) utilizes serial neurocognitive assessments and self-reported symptom inventories to assess recovery and safety for return to play (RTP). Because postconcussive RTP goals include symptom resolution and a return to neurocognitive baseline levels, clinical decisions rest in part on understanding modifiers of this baseline. Several studies have reported age and sex to influence baseline neurocognitive performance, but few have assessed the potential effect of sleep. We chose to investigate the effect of reported sleep duration on baseline Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) performance and the number of patient-reported symptoms. We hypothesized that athletes receiving less sleep before baseline testing would perform worse on neurocognitive metrics and report more symptoms. Cross-sectional study; Level of evidence, 3. We retrospectively reviewed 3686 nonconcussed athletes (2371 male, 1315 female; 3305 high school, 381 college) with baseline symptom and ImPACT neurocognitive scores. Patients were stratified into 3 groups based on self-reported sleep duration the night before testing: (1) short, sleep duration on baseline ImPACT performance. A univariate ANCOVA was performed to investigate the influence of sleep on total self-reported symptoms. When controlling for age and sex as covariates, the MANCOVA revealed significant group differences on ImPACT reaction time, verbal memory, and visual memory scores but not visual-motor (processing) speed scores. An ANCOVA also revealed significant group differences in total reported symptoms. For baseline symptoms and ImPACT scores, subsequent pairwise comparisons revealed these associations to be most significant when comparing the short and intermediate sleep groups. Our results indicate that athletes sleeping fewer than 7 hours before baseline testing perform worse on 3 of 4 ImPACT scores and report more symptoms. Because SRC management and RTP

This study compared low strain rate material properties and impact force attenuation of auxetic foam and the conventional open-cell polyurethane counterpart. This furthers our knowledge with regards to how best to apply these highly conformable and breathable auxetic foams to protective sports equipment. Cubes of auxetic foam measuring 150 × 150 × 150 mm were fabricated using a thermo–mechanical conversion process. Quasi-static compression confirmed the converted foam to be auxetic, prior to being sliced into 20 mm thick cuboid samples for further testing. Density, Poisson’s ratio and the stress–strain curve were all found to be dependent on the position of each cuboid from within the cube. Impact tests with a hemispherical drop hammer were performed for energies up to 6 J, on foams covered with a polypropylene sheet between 1 and 2 mm thick. Auxetic samples reduced peak force by ∼10 times in comparison to the conventional foam. This work has shown further potential for auxetic foam to be applied to protective equipment, while identifying that improved fabrication methods are required. (paper)

Since the introduction of the Orphan Drug Act (ODA) in 1983, orphan drug approvals in the United States have jumped from growth is widely attributed to the financial incentives the ODA gives to companies that develop these medicines, and it is likely to continue for a unique reason: partnerships between pharmaceutical firms and direct-to-consumer (DTC) genetic testing companies. This emerging trend is the subject of this article, which begins by considering how rare-disease drugs are regulated and the rising interest in nonclinical genetic testing. It then outlines how DTC companies analyze DNA and how their techniques benefit researchers and drug developers. Then, after an overview of the current partnerships between DTCs and drug developers, it examines concerns about privacy and cost brought up by these partnerships. The article concludes by contrasting the enormous positive potential of DTC-pharma relationships and their concomitant dangers, especially to consumer privacy and cost to the healthcare system.

Rational drug-testing programs attempt to balance the need for accuracy of the process with the need to preserve the rights and dignity of the people being tested. U.S. Department of Transportation regulations prescribe the specifics of how urine specimens are to be collected, how to inform the specimen donor of the process to which he or she will be subjected, and certification of laboratories by the National Institute of Drug Abuse. These guidelines are an effort to assure that each collection site and each laboratory testing the urine of employees adheres to certain basic standards of quality control.

Full Text Available Abstract Background This study investigates the use of anabolic androgenic steroids (AAS among a national representative sample of high school students in Iceland. We test several hypotheses drawn from three perspectives. The first perspective focuses on the use of AAS as an individual phenomenon motivated by the desire to succeed in sport. The second perspective views the use of AAS as shaped by norms and values embedded in social relationships of formally organized sport. The third perspective suggests that factors outside sport, which have been shown to correlate with the use of other substances, predict the use of AAS. Method We use logistic regression and predicted probabilities to analyze data from a national representative survey of 11031 Icelandic high school students. Results Our results indicated that the use of AAS is not significantly related to participation in formally organized sports. However, it positively relates to fitness and physical training in informal contexts. We found a relatively strong relationship between the use of AAS and the use of illicit substances and a moderate relationship between AAS use and alcohol and tobacco consumption. We also found a significant negative relationship between AAS use and school integration and school achievement, and a significant positive relationship between AAS use and school anomie. The relation between AAS use and family-related variables was weaker. Finally, we found that the relationship between sport participation, physical exercise, and AAS use varies across levels of anomie and integration. Conclusion Our findings suggest that the use of AAS and especially illegal substances should be considered more as a social and a health problem rather than a sport specific issue. We found that high school students participating in fitness and informal training outside of formally organized sport clubs are the main risk group and should be the target of prevention efforts. However, this

An on-site oral fluid drug screen, Oratect, was used to investigate the effects of adulterants and foodstuffs on oral fluid test results. Common foods, beverages, food ingredients, cosmetics and hygienic products were demonstrated not to cause false positive results when tested 30 min after their consumption. Evaluations of two commercial oral fluid adulterants, "Clear Choice Fizzy Flush" and "Test'in Spit n Kleen Mouthwash" suggest their mechanism of action is the clearing of residual drugs of abuse compounds through rinsing of the oral cavity. They do not directly destroy the drug compounds or change the pH of the oral fluid. It is also suggested that a common mouthwash would perform similar action.

Drug susceptibility testing (DST) of clinical isolates of Mycobacterium tuberculosis is critical in treating tuberculosis. We demonstrate the possibility of using a microbial sensor to perform DST of M. tuberculosis and shorten the time required for DST. The sensor is made of an oxygen electrode with M. tuberculosis cells attached to its surface. This sensor monitors the residual oxygen consumption of M. tuberculosis cells after treatment with anti-TB drugs with glycerine as a carbon source. In principle, after drug pretreatment for 4-5 days, the response differences between the sensors made of drug-sensitive isolates are distinguishable from the sensors made of drug-resistant isolates. The susceptibility of the M. tuberculosis H37Ra strain, its mutants and 35 clinical isolates to six common anti-TB drugs: rifampicin, isoniazid, streptomycin, ethambutol, levofloxacin and para-aminosalicylic acid were tested using the proposed method. The results agreed well with the gold standard method (LJ) and were determined in significantly less time. The whole procedure takes approximately 11 days and therefore has the potential to inform clinical decisions. To our knowledge, this is the first study that demonstrates the possible application of a dissolved oxygen electrode-based microbial sensor in M. tuberculosis drug resistance testing. This study used the microbial sensor to perform DST of M. tuberculosis and shorten the time required for DST. The overall detection result of the microbial sensor agreed well with that of the conventional LJ proportion method and takes less time than the existing phenotypic methods. In future studies, we will build an O 2 electrode array microbial sensor reactor to enable a high-throughput drug resistance analysis. © 2017 The Authors.

Drug provocation tests (DPTs) are important in the treatment of patients with drug hypersensitivity (DH), but they carry certain hypersensitivity reaction risks, which lead to procedure-related concerns in patients. To investigate DPT-related anxiety and its effect on long-term use of tested drugs. The study included patients who underwent DPT from July 1, 2009, to July 1, 2012. After recording the patients' history and characteristics, a variety of psychiatric (Hospital Anxiety and Depression Scale, Panic and Agoraphobia Scale, and the Maudsley Obsessive-Compulsive Inventory) and quality-of-life (36-item Short Form Health Survey) tests were performed. DPT-related anxiety was also evaluated using a visual analog scale. The patients were requestioned about whether they had used the tested drug within 1 year. A total of 126 patients were included in the study. According to the Hospital Anxiety and Depression Scale, 23.4% and 30.6% of the patients had depression and anxiety symptoms, respectively. The mean (SD) visual analog scale anxiety scores after a negative DPT result were lower than those before DPTs (2 [2.5] after vs 5.2 [3.4] before; P anxiety related to drug reactions, despite negative DPT results and symptoms indicated for use of the drug. Our findings suggest that DPTs in themselves cause significant anxiety in patients with DH. Importantly, anxiety levels decreased after a negative test result. However, our results also suggested that a negative DPT result is not convincing enough for some patients to use the tested drug when needed in the future. Therefore, supporting strategies appear to be the most effective way to eliminate DH-related anxiety of patients. Copyright © 2016 American College of Allergy, Asthma & Immunology.

In this article, the test implementation of a school-oriented drug prevention program "Study without Drugs" is discussed. The aims of this study were to determine the results of the process evaluation and to determine whether the proposed school-oriented drug prevention program during a pilot project was effective for the participating pupils. Sixty second-grade pupils at a junior high school in Paramaribo, Suriname participated in the test implementation. They were divided into two classes. For the process evaluation the students completed a structured questionnaire focusing on content and teaching method after every lesson. Lessons were qualified with a score from 0-10. The process was also evaluated by the teachers through structured interviews. Attention was paid to reach, dose delivered, dose received, fidelity, connection, achieved effects/observed behaviors, areas for improvement, and lesson strengths. The effect evaluation was conducted by using the General Liniair Model (repeated measure). The research (-design) was a pre-experimental design with pre-and post-test. No class or sex differences were detected among the pupils with regard to the assessment of content, methodology, and qualification of the lessons. Post-testing showed that participating pupils obtained an increased knowledge of drugs, their drug-resisting skills were enhanced, and behavior determinants (attitude, subjective norm, self-efficacy, and intention) became more negative towards drugs. From the results of the test implementation can be cautiously concluded that the program "Study without Drugs" may yield positive results when applied in schools). Thus, this pilot program can be considered a step towards the development and implementation of an evidence-based school-oriented program for pupils in Suriname.

This paper describes the goals and current practice of school-based random student drug testing (RSDT) as part of an overall drug prevention strategy, briefly explores the available literature evaluating its effectiveness and discusses the controversies related to RSDT. The authors describe the rationale for RSDT programs and the prevalence of RSDT and other drug testing programs in schools. Eight major criticisms and controversies in RSDT are discussed, including those related to acceptance of RSDT, program effectiveness, costs, legality and effects of drug testing on students. The limitations of the current literature are explored. Although there is limited empirical evidence to support or refute the efficacy of RSDT in schools, there remains substantial opposition to such programs, which may contribute to the paucity of empirical studies of RSDT. Rigorous long-term evaluations are needed to evaluate the effectiveness of various versions of RSDT programs to prevent drug use and identify students in need of assistance to become and stay drug-free. © 2012 The Authors, Addiction © 2012 Society for the Study of Addiction.
Full Text Available The present review addresses the literature regarding the sensitivity and specificity of the various diagnostic methods for evaluating non-immediate (ie, occurring more than 1 hour after drug administration hypersensitivity reactions associated with β-lactams and other antibiotics, anticonvulsants, heparins, iodinated contrast media, etc. Such reactions include several clinical entities, which range from mild reactions, such as maculopapular rash and delayed-appearing urticaria, to severe ones, such as acute generalized exanthematous pustulosis (AGEP, Stevens-Johnson syndrome, and toxic epidermal necrolysis (TEN. Clinical and laboratory studies indicate that a cell-mediated pathogenic mechanism is often involved in maculopapular rashes. However, this mechanism has also been demonstrated in other non-immediate reactions, such as urticarial and/or angioedematous manifestations, TEN, bullous exanthems, and AGEP. Patch tests, together with delayed-reading intradermal tests, lymphocyte transformation tests, and challenges, are useful tools for evaluating non-immediate drug eruptions. Patch tests can be performed with any form of commercial drugs and are safer than intradermal tests. However, patch tests are less sensitive than intradermal tests, and their sensitivity may vary, depending on the vehicle used.

To assess the deterrent effect of mandatory, random drug testing among high school (HS) athletes in a controlled setting. Two high schools, one with mandatory drug testing (DT) consent before sports participation, and a control school (C), without DT, were assessed during the 1999-2000 school year. Athletes (A) and nonathletes (NA) in each school completed confidential (A) or anonymous (NA) questionnaires developed for this study, respectively, at the beginning and end of the school year. Positive alcohol or drug tests required parent notification and mandatory counseling without team or school suspension. Thirty percent of the DT athletes were tested. Data were analyzed using the end of the school year measure, adjusted for the initial questionnaire results. Demographics of the athlete sample revealed that mean age was 15.5 years with 81.5% white, 9.6% Hispanic, 4.5% Asian, 2.6% American Indian/Native Alaskan, 1.3% African-American, and 1.3% Native Hawaiian/Pacific Islander. A (n = 276) and NA (n = 507) were assessed at the beginning (baseline) and at the end of the school year (A, n = 159; NA, n = 338). The past 30-day index of illicit drugs (4-fold difference) and athletic enhancing substances (3-fold difference) were lower (p drug use risk factors, including norms of use, belief in lower risk of drugs, and poorer attitudes toward the school, increased among DT athletes (p drug use index was present among nonathletes at the DT school, at the end of the school year, it did not achieve statistical significance (p drug prevention approach.

In recent decades, urine drug testing in the workplace has become common in many countries in the world. There have been several studies concerning the use of the urine specimen validity test (SVT) for drug abuse testing administered in the workplace. However, very little data exists concerning the urine SVT on drug abuse tests from court specimens, including dilute, substituted, adulterated, and invalid tests. We investigated 21,696 submitted urine drug test samples for SVT from workplace and court settings in southern Taiwan over 5 years. All immunoassay screen-positive urine specimen drug tests were confirmed by gas chromatography/mass spectrometry. We found that the mean 5-year prevalence of tampering (dilute, substituted, or invalid tests) in urine specimens from the workplace and court settings were 1.09% and 3.81%, respectively. The mean 5-year percentage of dilute, substituted, and invalid urine specimens from the workplace were 89.2%, 6.8%, and 4.1%, respectively. The mean 5-year percentage of dilute, substituted, and invalid urine specimens from the court were 94.8%, 1.4%, and 3.8%, respectively. No adulterated cases were found among the workplace or court samples. The most common drug identified from the workplace specimens was amphetamine, followed by opiates. The most common drug identified from the court specimens was ketamine, followed by amphetamine. We suggest that all urine specimens taken for drug testing from both the workplace and court settings need to be tested for validity. Copyright © 2017. Published by Elsevier B.V.

Full Text Available Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs and anaplastic lymphoma kinase (ALK inhibitors have dramatically changed the strategy of medical treatment of lung cancer. Patients should be screened for the presence of the EGFR mutation or echinoderm microtubule-associated protein-like 4 (EML4-ALK fusion gene prior to chemotherapy to predict their clinical response. The succinate dehydrogenase inhibition (SDI test and collagen gel droplet embedded culture drug sensitivity test (CD-DST are established in vitro drug sensitivity tests, which may predict the sensitivity of patients to cytotoxic anticancer drugs. We applied in vitro drug sensitivity tests for cyclopedic prediction of clinical responses to different molecular targeting drugs.The growth inhibitory effects of erlotinib and crizotinib were confirmed for lung cancer cell lines using SDI and CD-DST. The sensitivity of 35 cases of surgically resected lung cancer to erlotinib was examined using SDI or CD-DST, and compared with EGFR mutation status.HCC827 (Exon19: E746-A750 del and H3122 (EML4-ALK cells were inhibited by lower concentrations of erlotinib and crizotinib, respectively than A549, H460, and H1975 (L858R+T790M cells were. The viability of the surgically resected lung cancer was 60.0 ± 9.8 and 86.8 ± 13.9% in EGFR-mutants vs. wild types in the SDI (p = 0.0003. The cell viability was 33.5 ± 21.2 and 79.0 ± 18.6% in EGFR mutants vs. wild-type cases (p = 0.026 in CD-DST.In vitro drug sensitivity evaluated by either SDI or CD-DST correlated with EGFR gene status. Therefore, SDI and CD-DST may be useful predictors of potential clinical responses to the molecular anticancer drugs, cyclopedically.

Field sport coaches must use reliable and valid tests to assess change-of-direction speed in their athletes. Few tests feature linear sprinting with acute change- of-direction maneuvers. The Change-of-Direction and Acceleration Test (CODAT) was designed to assess field sport change-of-direction speed, and includes a linear 5-meter (m) sprint, 45° and 90° cuts, 3- m sprints to the left and right, and a linear 10-m sprint. This study analyzed the reliability and validity of this test, through comparisons to 20-m sprint (0-5, 0-10, 0-20 m intervals) and Illinois agility run (IAR) performance. Eighteen Australian footballers (age = 23.83 ± 7.04 yrs; height = 1.79 ± 0.06 m; mass = 85.36 ± 13.21 kg) were recruited. Following familiarization, subjects completed the 20-m sprint, CODAT, and IAR in 2 sessions, 48 hours apart. Intra-class correlation coefficients (ICC) assessed relative reliability. Absolute reliability was analyzed through paired samples t-tests (p ≤ 0.05) determining between-session differences. Typical error (TE), coefficient of variation (CV), and differences between the TE and smallest worthwhile change (SWC), also assessed absolute reliability and test usefulness. For the validity analysis, Pearson's correlations (p ≤ 0.05) analyzed between-test relationships. Results showed no between-session differences for any test (p = 0.19-0.86). CODAT time averaged ~6 s, and the ICC and CV equaled 0.84 and 3.0%, respectively. The homogeneous sample of Australian footballers meant that the CODAT's TE (0.19 s) exceeded the usual 0.2 x standard deviation (SD) SWC (0.10 s). However, the CODAT is capable of detecting moderate performance changes (SWC calculated as 0.5 x SD = 0.25 s). There was a near perfect correlation between the CODAT and IAR (r = 0.92), and very large correlations with the 20-m sprint (r = 0.75-0.76), suggesting that the CODAT was a valid change-of-direction speed test. Due to movement specificity, the CODAT has value for field sport

The ICH S8 immunotoxicity testing guideline for human pharmaceuticals was published in 2006 and was intended to provide guidance for assessing the immunotoxicity potential of low-molecular-weight drugs that are not intended to alter the immune system. For drugs intended to modulate the immune system, immunotoxicity testing strategies are generally developed on a case-by-case approach since the targets, intended patient population, and mechanisms of action of the test compound will determine the type of testing needed. Some of the general principles of ICH S8, however, may be applied to immunotoxicity testing strategies for immunomodulatory drugs. A weight-of-evidence approach using factors discussed in ICH S8 in concert with an assessment of the potential value of additional immunotoxicity testing should be considered. For most situations, immunotoxicity studies with immunomodulatory compounds evaluate off-target effects on the immune system and exaggerated pharmacology. The potential use of data from these studies and considerations such as translatability to humans are discussed.
45 subjects were assessed for cognitive anxiety on the Sport Competition Anxiety Test. Two months later they observed a person performing a new motor task which required high cognitive processing to be performed well. After this observation, 22 subjects were randomly assigned to a Mental Practice and 23 to a Control group. The former performed a cognitive rehearsal of the task, whereas the latter did not. None practiced the task physically before being tested. Analysis of variance showed that both errors and performance time interacted significantly with Mental Practice versus Control group scores and scores on the Sport Competition Anxiety Test. Among subjects who practiced mentally, those scoring low on cognitive anxiety performed significantly better than subjects who scored high. Further, the relationship between test scores of cognitive anxiety and performance for the total sample was analysed by different curvilinear regression models. The cubic model fitted the data better and accounted for a greater percent of variance on error performance explained by anxiety test scores (R = .39) than the linear correlation (r = .25). This cubic model formed a polynomial relationship between cognitive anxiety test scores and error in performance.

The terms 'false-positive' and 'false-negative' are widely used in discussions of urine drug test (UDT) results. These terms are inadequate because they are used in different ways by physicians and laboratory professionals and they are too narrow to encompass the larger universe of potentially misleading, inappropriate and unexpected drug test results. This larger universe, while not solely comprised of technically 'true' or 'false' positive or negative test results, presents comparable interpretive challenges with corresponding clinical implications. In this review, we propose the terms 'potentially inappropriate' positive or negative test results in reference to UDT results that are ambiguous or unexpected and subject to misinterpretation. Causes of potentially inappropriate positive UDT results include in vivo metabolic conversions of a drug, exposure to nonillicit sources of a drug and laboratory error. Causes of potentially inappropriate negative UDT results include limited assay specificity, absence of drug in the urine, presence of drug in the urine, but below established assay cutoff, specimen manipulation and laboratory error. Clinical UDT interpretation is a complicated task requiring knowledge of recent prescription, over-the-counter and herbal drug administration, drug metabolism and analytical sensitivities and specificities.

Artemisinin-based combination therapies are the frontline treatment of Plasmodium falciparum malaria. The circulation of falsified and substandard artemisinin-based antimalarials in Southeast Asia has been a major predicament for the malaria elimination campaign. To provide an update of this situation, we purchased 153 artemisinin-containing antimalarials, as convenience samples, in private drug stores from different regions of Myanmar. The quality of these drugs in terms of their artemisinin derivative content was tested using specific dipsticks for these artemisinin derivatives, as point-of-care devices. A subset of these samples was further tested by high-performance liquid chromatography (HPLC). This survey identified that > 35% of the collected drugs were oral artesunate and artemether monotherapies. When tested with the dipsticks, all but one sample passed the assays, indicating that the detected artemisinin derivative content corresponded approximately to the labeled contents. However, one artesunate injection sample was found to contain no active ingredient at all by the dipstick assay and subsequent HPLC analysis. The continued circulation of oral monotherapies and the description, for the first time, of falsified parenteral artesunate provides a worrisome picture of the antimalarial drug quality in Myanmar during the malaria elimination phase, a situation that deserves more oversight from regulatory authorities.

This manuscript reviews data available in the scientific literature relative to drug testing for the five mandated drug classes and circumstances other than abuse of the drug itself that could result in a positive test. For marijuana, passive inhalation, unknowing oral ingestion, and the use of Marinol are discussed. Data are presented on the concentration of delta9-tetrahydrocannabinol (THC) and its precursors, acid-A and acid-B, in illicit marijuana and the extent of extraction of THC in boiled (tea) or cooked products. For cocaine, passive inhalation and passive exposure issues are reviewed. For opiates, poppy seed ingestion and guidelines for exclusion of poppy seeds as a cause for a positive test are discussed. For amphetamines, issues such as the presence of other phenethylamines, l-methamphetamine (Vicks' inhalers), and other prescription drugs are discussed. Although passive inhalation of methamphetamine and phencyclidine is theoretically possible, no data were available on these issues.

Full Text Available An estimated 8 million persons, mainly in Latin America, are infected with Trypanosoma cruzi, the etiologic agent of Chagas disease. Existing antiparasitic drugs for Chagas disease have significant toxicities and suboptimal effectiveness, hence new therapeutic strategies need to be devised to address this neglected tropical disease. Due to the high research and development costs of bringing new chemical entities to the clinic, we and others have investigated the strategy of repurposing existing drugs for Chagas disease. Screens of FDA-approved drugs (described in this paper have revealed a variety of chemical classes that have growth inhibitory activity against mammalian stage Trypanosoma cruzi parasites. Aside from azole antifungal drugs that have low or sub-nanomolar activity, most of the active compounds revealed in these screens have effective concentrations causing 50% inhibition (EC50's in the low micromolar or high nanomolar range. For example, we have identified an antihistamine (clemastine, EC50 of 0.4 µM, a selective serotonin reuptake inhibitor (fluoxetine, EC50 of 4.4 µM, and an antifolate drug (pyrimethamine, EC50 of 3.8 µM and others. When tested alone in the murine model of Trypanosoma cruzi infection, most compounds had insufficient efficacy to lower parasitemia thus we investigated using combinations of compounds for additive or synergistic activity. Twenty-four active compounds were screened in vitro in all possible combinations. Follow up isobologram studies showed at least 8 drug pairs to have synergistic activity on T. cruzi growth. The combination of the calcium channel blocker, amlodipine, plus the antifungal drug, posaconazole, was found to be more effective at lowering parasitemia in mice than either drug alone, as was the combination of clemastine and posaconazole. Using combinations of FDA-approved drugs is a promising strategy for developing new treatments for Chagas disease.

Physicians have struggled with the medical ramifications of athletic competition since ancient Greece, where rational medicine and organized athletics originated. Historically, the relationship between sport and medicine was adversarial because of conflicts between health and sport. However, modern sports medicine has emerged with the goal of improving performance and preventing injury, and the concept of the "team physician" has become an integral part of athletic culture. With this distinction come unique ethical challenges because the customary ethical norms for most forms of clinical practice, such as confidentiality and patient autonomy, cannot be translated easily into sports medicine. The particular areas of medical ethics that present unique challenges in sports medicine are informed consent, third parties, advertising, confidentiality, drug use, and innovative technology. Unfortunately, there is no widely accepted code of sports medicine ethics that adequately addresses these issues.

Skin tests are of paramount importance for the evaluation of drug hypersensitivity reactions. Drug skin tests are often not carried out because of lack of concise information on specific test concentrations. The diagnosis of drug allergy is often based on history alone, which is an unreliable indicator of true hypersensitivity.To promote and standardize reproducible skin testing with safe and nonirritant drug concentrations in the clinical practice, the European Network and European Academy of Allergy and Clinical Immunology (EAACI) Interest Group on Drug Allergy has performed a literature search on skin test drug concentration in MEDLINE and EMBASE, reviewed and evaluated the literature in five languages using the GRADE system for quality of evidence and strength of recommendation. Where the literature is poor, we have taken into consideration the collective experience of the group.We recommend drug concentration for skin testing aiming to achieve a specificity of at least 95%. It has been possible to recommend specific drug concentration for betalactam antibiotics, perioperative drugs, heparins, platinum salts and radiocontrast media. For many other drugs, there is insufficient evidence to recommend appropriate drug concentration. There is urgent need for multicentre studies designed to establish and validate drug skin test concentration using standard protocols. For most drugs, sensitivity of skin testing is higher in immediate hypersensitivity compared to nonimmediate hypersensitivity. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The theory of planned behavior has been applied to sports and exercise behaviors. According to this theory, human intention to take action in a specific context is guided by three antecedents: attitude, subjective norm, and perceived behavioral control. Behavioral intention mediates the relationships between these three considerations and its ultimate performance. However, this theory has seldom been applied to the behaviors of spectators of sporting events. A sample of 269 volleyball spectators in Taiwan was studied to examine whether people's intention mediated their attitudes, subjective norms, and perceived behavioral control toward a given behavior, watching the 2010 Fédération Internationale de Volleyball World Grand Prix in Taipei. Regression analyses did not support behavioral intention as a mediator. This result is discussed in the context of planned behavior.

The thrombin generation test was used to assess the whole coagulation cascade in normal and factor-deficient human blood plasma. Potential therapeutic windows were estimated for coagulation factors, ranking them as targets for anticoagulant drugs. Thrombin and factor Xa have been revealed as the most promising targets, which fully agrees with the current drug development strategy. Inhibitors of factors Va and VIIa are expected to have narrow therapeutic windows. Inhibitors of factors VIIIa and IXa are expected to have a moderate anticoagulant effect. Factors XI and XII are poor targets for anticoagulant drugs. Compared with plasma that is deficient in factor II, the thrombin inhibitors bivalirudin and aptamer HD1 had increased activity. Both inhibitors were tested in deficient plasma providing a model of potential drug combination. The most promising combinations were anti-thrombin with anti-V/Va and also anti-thrombin with anti-IX/IXa. Each combination had an incremental dose-effect dependence that is promising from the standpoint of the therapeutic window.

With the persisting increase of drug-resistant stains of M. Tuberculosis around the world, rapid and sensitive detection of antibiotic of M. Tuberculosis is becoming more and more important. In the present study, drug susceptibility of M. tuberculosis were detected by recombination mycobacteriophage combined with bioluminescence sensor. It is based on the use of recombination mycobacteriophage which can express firefly luciferase when it infects viable mycobacteria, and can effectively produce quantifiable photon. Meanwhile, in mycobacterium cells treated with active antibiotic, no light is observed. The emitted light is recorded by a bioluminscence sensor, so the result of drug-resistant test can be determined by the naked eye. 159 stains of M. tuberculosis were applied to this test on their resistant to rifampin, streptomycin and isoniazid. It is found that the agreement of this assay with Liewenstein- Jensen slat is: rifampin 95.60 percent, isoniazid 91.82 percent, streptomycin 88.68 percent, which showed that it is a fast and practical method to scene and detect drug resistant of mycobacterium stains.
Conclusions: Reliable and timely detection of drug-resistant TB is needed, which is best achieved with molecular assays. In this author's opinion, rapid detection of resistance to isoniazid should be included with rifampicin resistance examination. In MDR, timely detection of the XDR defining agents and PZA is urgently needed. Development and validation of such tests should be a priority, as well as establishing QMS for the implementation and routine use of molecular rapid diagnostics. Each country should develop national diagnostic algorithms for how, when and where rapid molecular assays should be used for early detection of drug-resistant TB.

The Limulus test, which has been adopted as the Test for Bacterial Endotoxins in the JP XII, can detect or quantitate endotoxins of Gram-negative bacterial origin using blood corpuscle extracts (Limulus amebocyte lysate, LAL) of horseshoe crabs (Limulus polyphemus, Tachypleus tridentatus, etc.). It may be conducted by the gel-clot or spectrophotometric (turbidimetric and colorimetric) techniques, the former being based on gel formation due to the activation of LAL by endotoxins. The turbidimetric technique is based on the LAL turbidity change during the gel formation and the colorimetric technique on activation of peptide hydrolytic enzymes in LAL. The Limulus test has been unofficially utilized as a simple and highly sensitive method for the determination of endotoxins in parenteral drugs in lieu of the in vivo Pyrogen Test using rabbits. For the Bacterial Endotoxins Test of the JP XII, the gel-clot technique alone was adopted, the technique being only allowed for Injection. Although most parenteral drugs show inhibition or enhancement in practice, this test can be most easily conducted by eliminating interfering effects through dilution of specimens by a factor not exceeding the maximum valid dilution (MVD) with water. Since MVD is dependent on the sensitivity of applied methodology, the turbidimetric and colorimetric techniques, which are more sensitive than the gel-clot technique, have a distinct advantage. The JP, as the leading Pharmacopoeia for the international harmonization of Bacterial Endotoxins Testing, has presented a "Draft towards International Harmonization of Bacterial Endotoxins Test", whose main purpose is the introduction of supplementary turbidimetric and colorimetric techniques. Under these circumstances the following subjects are discussed: (1) the proposal that, with a view towards international harmonization of the technical requirements of Pharmacopoeias, both the turbidimetric and colorimetic techniques should be included together with

No standardized return-to-activity or sport guidelines currently exist after anterior cruciate ligament (ACL) reconstruction. Isokinetic testing and unilateral hop testing, which have construct validity, are often used to make the determination of when a patient is ready to return to sport. Neither of these measures has been reported to be predictive of subsequent injuries. To compare the performance on 2 functional tests of ACL reconstruction patients released to return to activity versus those who have not been released based on clinical impairment measures. Cohort study; Level of evidence, 3. A total of 98 patients were examined by the treating orthopaedic surgeon 6 months after ACL reconstruction for traditional impairment measures, including swelling, range of motion, strength, and graft stability. After this examination, all subjects completed the functional testing, consisting of the Functional Movement Screen (FMS) and the Lower Quarter Y Balance Test (YBT-LQ), by an experienced tester who was blinded to the results of the clinical examination. On the basis of the clinical examination, all patients were grouped as being ready to return to sport or not being ready. Performance on the functional tests, as measured by overall performance and side-to-side asymmetry, was compared between the 2 groups using independent-samples t tests (P < .05). No difference existed between the groups with regard to the descriptive characteristics, with the exception that the group not cleared was younger (21.0 ± 7.4 years) than the group that was cleared (25.6 ± 13.2 years). Performance on the YBT-LQ revealed that no differences existed between groups when examining reach symmetry for any of the reach directions. In addition, no differences were found between groups when looking at the average reach score normalized to limb length for either the surgical or nonsurgical leg. Patients in the cleared group exhibited a similar score on the FMS (12.7 ± 2.9) compared with the

Valid patient-based outcome instruments are necessary for comprehensive patient care that focuses on all aspects of health, from impairments to participation restrictions. To validate the Slovenian translation of Medical Outcome Survey (MOS) Short Form Health Survey (SF-36) and to assess relations among various knee measurements, activity tested with Oxford Knee Score (OKS) and health-related quality of life as estimated with SF-36 domains. Descriptive validation study. Isokinetic laboratory in outpatient rehabilitation unit. 101 subjects after unilateral sport knee injury. All subjects completed the SF-36 and OKS, and isokinetic knee-muscle strength output at 60°/s was determined in 78 participants. Within a 3-d period, 43 subjects completed the SF-36 and OKS questionnaires again. Reliability testing included internal consistency and test-retest reliability. Correlations between SF-36 subscales and OKS were calculated to assess construct validity, and correlation between SF-36 subscales and muscle strength was calculated to assess concurrent validity. Chronbach α was above .78 for all SF-36 subscales. ICCs ranged from .80 to .93. The correlation between OKS and the physical-functioning subscale, showing convergent construct validity, was higher (r = .83, P social-functioning (r = -.43, P sport knee injury were established.

Workplace Drug Testing (WDT) in Italy includes two levels of monitoring: a first stage concerning drug testing on urine samples and a second involving both urine and hair analysis. The second stage is performed only on workers who tested positive at the first level. We analyzed urine and hair specimens from 120 workers undergoing second-level testing between 2009 and 2012. Eighty percent of them had tested positive for cannabinoids during the first level analysis, and 15.8% for cocaine. Both urine and hair samples were analyzed in order to find the following drugs of abuse: amphetamines, buprenorphine, cannabinoids, cocaine, ecstasy, methadone, and opiates. Urine analyses were performed by immunological screening (EMIT); urine confirmatory tests and hair analyses were performed by gas chromatography-mass spectrometry (GC-MS). As regards second-stage testing on urine samples, 71.2% of workers were always negative, whereas 23.9% tested positive at least once for cannabinoids and 2.5% for cocaine. Hair analyses produced surprising results: 61.9% of hair samples tested negative, only 6.2% tested positive for cannabinoids, whereas 28.8% tested positive for cocaine. These findings confirm that second-level surveillance of WDT, which includes hair analysis, is very effective because it highlights drug intake - sometimes heavy - that cannot be revealed only through urine analyses. The employees for whom drug addiction is proved can begin rehabilitation, while keeping their job. Eventually, our results confirmed the widespread and undeclared use of cocaine in Italy.

This study presents the case of a 4-year-old healthy child admitted to the paediatric ward for suspected accidental intoxication due to ingestion of narcoleptic drugs (methylphenidate, sertraline and quetiapine), taken on a regular basis by his 8-year-old brother affected by Asperger syndrome.Intoxication can be objectively assessed by measurements of drugs and metabolites in biological matrices with short-term (blood and urine) or long-term (hair) detection windows. At the hospital, the child's blood and urine were analysed by immunoassay (confirmed by liquid chromatography-mass spectrometry), and sertraline and quetiapine and their metabolites were identified. The suspicion that the mother administered drugs chronically prompted the analysis of six, consecutive 2-cm segments of the child's hair, using ultra-high performance liquid chromatography-tandem mass spectrometry, thereby accounting for ingestion over the previous 12 months. Quetiapine was found in the first four segments with a mean concentration of 1.00 ng/mg ± 0.94 ng/mg hair while sertraline and its metabolite, desmethyl-sertraline, were found in all segments with a mean concentration of 2.65 ± 0.94 ng/mg and 1.50 ± 0.94 ng/mg hair, respectively. Hair analyses were negative for methylphenidate and its metabolite (ritalinic acid). Biological matrices testing for psychoactive drugs disclosed both acute and chronic intoxication with quetiapine and sertraline administered by the mother.

Additional high-quality prospective studies are needed to better define the objective criteria used in relation to return-to-sport decisions after anterior cruciate ligament (ACL) reconstruction in active populations. To investigate prospectively the relationship between functional performance test results at 24 weeks postoperative and return-to-sport activity (Tegner activity score) at 12 and 24 months, respectively, after synthetic (ligament advanced reinforcement system [LARS]) and autograft (doubled semitendinosus/gracilis [2ST/2GR]) ACL reconstructions. Case series; Level of evidence, 4. A total of 64 patients who underwent ACL reconstruction (32 LARS, 32 2ST/2GR autograft; mean age, 27.9 years; body mass index [BMI], 24.9 kg/m 2 ) were assessed preoperatively and at staged intervals postoperatively up to 24 weeks for isokinetic testing of quadriceps and hamstring average power per repetition at 60 deg/s and 180 deg/s, a battery of hop tests, peak vertical ground-reaction force (vGRF), and time to peak vGRF (in seconds) during a step- and jump-down task onto a force platform and peak speed (m/s) using a global positioning system (GPS unit) during a running task. A cohort of 32 healthy matched participants (mean age, 26.31 years; BMI, 25.7 kg/m 2 ) were also tested to act as reference. Pearson correlation was calculated to assess correlation of each performance measure at 24 weeks postoperative with activity outcomes (Tegner score) at 12 and 24 months. The strongest correlation between physical performance tests and return-to-sport outcomes was observed with peak speed during running. Large correlations were also observed for hamstring isokinetic power and hop test for distance. Moderate correlations were observed for timed hop, peak vGRF during a jump-down task, and quadriceps isokinetic power. No statistical correlations were observed for time to peak vGRF during a step-down and jump-down task as well as peak vGRF during a step-down task. When the performance

The relationships between sport and sexuality in males are of great social and clinical interest, because of sports and motor activities that highly promote social and sexual relationships. Even if few literature exist, two main questions should be taken into account: whether and how physical exercise and sport positively or negatively influence sexual health and behavior and/or whether and how sexual behavior may affect a sub-sequent sport performance. Physical exercise and sport per se can influence, positively or negatively, the hypothalamic-pituitary-testicular axis function and, consequently, the individual's reproductive and/or sexual health. This depends on individual factors such as genetic and epigenetic ones and on different variables involved in the practice of sport activities (type of sport, intensity and duration of training, doping and drug use and abuse, nutrition, supplements, psychological stress, allostatic load, etc.). If well conducted, motor and sport activities could have beneficial effects on sexual health in males. Among different lifestyle changes, influencing sexual health, regular physical activity is fundamental to antagonize the onset of erectile dysfunction (ED). However, competitive sport can lead both reproductive and/or sexual tract damages and dysfunctions, transient (genital pain, hypoesthesia of the genitalia, hypogonadism, DE, altered sexual drive, etc.) or permanent (hypogonadism, DE, etc.), by acting directly (traumas of the external genitalia, saddle-related disorders in cyclists, etc.) or indirectly (exercise-related hypogonadism, drug abuse, doping, stress, etc.). Sexual activities shortly performed before a sport competition could differently influence sport performance. Due to the few existing data, it is advisable to avoid an absolute pre-competition sexual abstinence.

Cross-sectional. Objectives To compare performance on the modified Star Excursion Balance Test (SEBT) between participants with anterior cruciate ligament reconstruction (ACLR) at the time of return to sport and uninjured control participants. The modified SEBT is a clinical tool to assess neuromuscular control deficits. Deficits in dynamic stability and neuromuscular control persist after ACLR, but assessment with the modified SEBT in this population at the time of return to sport has not been reported. Sixty-six participants (mean age, 17.6 years) at the time of return to sport following unilateral primary ACLR (ACLR group) and 47 uninjured participants (mean age, 17.0 years) serving as a control group participated. For the modified SEBT, the anterior, posteromedial, and posterolateral reach distances were recorded. Lower extremity muscle strength was quantified with isokinetic dynamometry. Independent-sample t tests were used to evaluate performance differences between the ACLR group and the control group and between the ACLR subgroups. In the ACLR group, bivariate correlations determined the association of modified SEBT performance with time since surgery and lower extremity muscle strength. The ACLR group had lower anterior reach distances on the involved and uninvolved limbs compared to the control group. There were no differences observed between groups in reach distances for the posteromedial and posterolateral directions or in limb symmetry indices for any of the reach directions. In the ACLR group, time from surgery and meniscal status at the time of ACLR did not influence modified SEBT performance, whereas participants with patellar bone-tendon-bone grafts had a lower posterolateral reach distance compared to those with hamstring grafts. In the ACLR group, involved-limb hip abduction strength positively correlated with all reach distances, and quadriceps strength positively correlated with posterolateral reach. At the time of return to sport

Prion diseases belong to a group of fatal infectious diseases with no effective therapies available. Throughout the last 35 years, less than 50 different drugs have been tested in different experimental animal models without hopeful results. An important limitation when searching for new drugs is the existence of appropriate models of the disease. The three different possible origins of prion diseases require the existence of different animal models for testing anti-prion compounds. Wild type, over-expressing transgenic mice and other more sophisticated animal models have been used to evaluate a diversity of compounds which some of them were previously tested in different in vitro experimental models. The complexity of prion diseases will require more pre-screening studies, reliable sporadic (or spontaneous) animal models and accurate chemical modifications of the selected compounds before having an effective therapy against human prion diseases. This review is intended to put on display the more relevant animal models that have been used in the search of new antiprion therapies and describe some possible procedures when handling chemical compounds presumed to have anti-prion activity prior to testing them in animal models.

Medial patellofemoral ligament (MPFL) reconstruction and tibial tubercle osteotomy are commonly used to treat recurrent lateral patellar instability, yet there are limited available data on return to sport (RTS) following these procedures. The purpose of this study is to evaluate patient factors associated with excellent functional outcomes, including successful RTS, following surgical stabilization including MPFL reconstruction in competitive athletes with recurrent lateral patellar instability. Athletes undergoing primary MPFL reconstruction for recurrent lateral instability from 2005 to 2013 were identified at a single institution. Concomitant procedures, such as tibial tubercle osteotomy (TTO), were included. Patient demographic information, including BMI, gender, age, and pre-injury Tegner score, was recorded. In addition, radiographs were reviewed for pre-operative patellar height (Caton-Deschamps index) and trochlear dysplasia (Dejour classification). All patients underwent a standardized rehabilitation/post-operative protocol, with isokinetic strength and functional testing being performed at 6 months post-operatively. Final Tegner scores, RTS status, subjective instability ratings, and Kujala scores were collected at a minimum of 2 years. Chi-squared analysis for categorical variables and Wilcoxon rank-sum analysis for continuous variables were used to determine the relationship between the previously mentioned patient and knee characteristics with isokinetic data, RTS status, or Kujala scores. Thirty-nine athletes (23 male, 16 female) at a mean age of 17.5 ± 2.9 years (range, 13-26) underwent primary MPFL reconstruction (32 autografts, seven allografts) for recurrent patellar instability with a mean follow-up of 47.0 ± 16.4 months. Sixteen patients (41%) underwent concomitant tibial tubercle osteotomies. Isokinetic data collected at 6 months post-operatively demonstrated mean knee flexion and extension strength deficits of 15.8 ± 10.1% and

Full Text Available El objetivo de este estudio fue el desarrollo y evaluación métrica del Test Motor SportComp, instrumento diseñado para ayudar a los profesores de educación física en la evaluación de la coordinación motriz global de sus alumnos de Educación Secundaria. En la actualidad no existen tests que evalúen la coordinación motriz de forma válida y fiable y que puedan ser empleados por el profesorado de educación física en el contexto de sus clases de manera rápida y económica. El presente test se construyó a partir de una revisión de la literatura científica sobre medición motriz entre los 12 y 17 años. La validez de contenido de las pruebas empleadas fue evaluada por expertos y las pruebas seleccionadas fueron aplicadas a 5732 escolares de estas edades. Se analizaron los resultados mediante la técnica de componentes principales que permitió la extracción de un solo factor formado por 5 tareas motrices relacionadas con la coordinación motriz global. El Coeficiente de Correlación Intraclase (CCI permitió obtener una fiabilidad test-retest de (CCI=0,91. Asimismo, mostró una satisfactoria validez criterial con la batería MABC-2 uno de los más reconocidos para la detección de problemas de coordinación motriz. Las propiedades métricas del presente test son muy satisfactorias y ofrecen buenas posibilidades para ser empleado por los profesores de educación física en sus clases por su bajo coste económico, poco tiempo de aplicación reclamado y poseer normas ajustadas por edad y sexo.

High-profile sportspeople are posited as role models for others. We examine whether university sportspeople and non-sportspeople's perceptions of high-profile sportspeople's (sports stars) and friends perceived drinking behaviours are related to their own drinking behaviours. Further, we examine the importance of drinking with competitors after sports events. A convenience sample of 1028 participants (58% females, n=652 sportspeople) from two Australian universities were approached at sporting and university venues. Participants completed a survey booklet containing demographic questions, the Alcohol Use Disorders Identification Test (AUDIT, alcohol measure), perceived drinking of high-profile sportspeople and friends (social norms), and for sportspeople only, items assessing the importance of drinking with competitors. Bivariate and multivariate analyses were used to assess relationships. Both sporting and non-sporting participants perceived high-profile sportspeople to drink less than themselves and their friends. Small significant bivariate relationships were found between high-profile sportspeople's perceived drinking and self-reported drinking for sportspeople (r=0.20, P Friends' and normative drinking practices were predictors of drinking.[O'Brien KS, Kolt GS, Webber A, Hunter JA.

In its seventh report, published in 1960, the WHO Expert Committee on Tuberculosis “noted the need for international standards for the definition and determination of drug resistance which will permit comparisons to be made from one area to another, and recommended that the World Health Organization take appropriate steps to establish such standards”.10 Acting on this recommendation, WHO took the first step towards standardization by convening in Geneva, in December 1961, an informal international meeting of specialists in the bacteriology of tuberculosis. At this meeting an attempt was made to formulate prerequisites for reliable sensitivity tests and to specify the technical procedures for them. The first part of the present paper is a joint contribution by the participants in the meeting, summarizing the general conclusions reached and recommendations made with regard to tests of sensitivity to the three main antituberculosis drugs—isoniazid, streptomycin and p-aminosalicylic acid. The other three parts describe, in turn, three different tests for determining drug sensitivity—the absolute-concentration method, the resistance-ratio method and the proportion method—that are generally considered to give reasonably accurate results.

Aniracetam, 1-p-anisoyl-2-pyrrolidinone, is known to be a nootropic or cognitive activator. Aniracetam protects against memory and learning deficits without causing effects on motor function and the autonomic nervous system. A drug dependence study on aniracetam utilizing the intragastric route of administration was performed in male cynomolgus monkeys. The behavioral observation test after acute administration revealed that aniracetam at the dose of 25-400 mg/kg did not change the gross behavior. In the self-administration initiation test, animals were exposed to two or three unit doses of aniracetam and references for a total available period of 7 weeks. Aniracetam at the dose of 25, 50 and 75 mg/kg/injection did not initiate self-administration in the respective group of 4, 4 and 2 animals. In the study with d-methamphetamine hydrochloride at the dose of 0.1 mg/kg/injection, 1 out of 4 animals started to consistently self-administer the drug. Self-administration of cocaine hydrochloride at the dose of 10 mg/kg/injection was confirmed in 3 out of 5 animals, and these 3 animals died from overdosing later. In the physical dependence direct induction test, animals received aniracetam (50 mg/kg) and sodium pentobarbital (25 mg/kg: the dose inducing intermediate CNS depression) intragastrically twice a day for 31 consecutive days. Abrupt withdrawal of aniracetam did not elicit abstinent signs (including changes in appetite and body weight) in all 6 animals, whereas withdrawal of pentobarbital produced typical abstinent behavioral signs and decreases in appetite and body weight. In conclusion, aniracetam was confirmed to develop neither physical dependence nor psychic dependence in cynomolgus monkeys.

Doping testing is a key component enforced by anti-doping authorities to detect and deter doping in sport. Policy is developed to protect athletes' right to participate in doping-free sport; and testing is a key tool to secure this right. Accordingly, athletes' responses to anti-doping efforts.......e., the efforts of stakeholders involved in testing) in their own sport both nationally and worldwide. Moreover, it seeks to identify whether specific factors such as previous experience of testing and perceived proximity of doping have an impact on athletes' perceptions of the testing system. The study comprises...... a web-based questionnaire (N = 645; response rate 43%) and uses qualitative findings to elaborate on and explain quantitative results. Results showed that two-thirds of the athletes reported the national testing programme in their sport to be appropriate. A majority of the athletes who had an opinion...
Full Text Available Claudia L Reardon, Shane Creado Department of Psychiatry, University of Wisconsin School of Medicine and Public Health, Madison, WI, USA Abstract: Drug abuse occurs in all sports and at most levels of competition. Athletic life may lead to drug abuse for a number of reasons, including for performance enhancement, to self-treat otherwise untreated mental illness, and to deal with stressors, such as pressure to perform, injuries, physical pain, and retirement from sport. This review examines the history of doping in athletes, the effects of different classes of substances used for doping, side effects of doping, the role of anti-doping organizations, and treatment of affected athletes. Doping goes back to ancient times, prior to the development of organized sports. Performance-enhancing drugs have continued to evolve, with “advances” in doping strategies driven by improved drug testing detection methods and advances in scientific research that can lead to the discovery and use of substances that may later be banned. Many sports organizations have come to ban the use of performance-enhancing drugs and have very strict consequences for people caught using them. There is variable evidence for the performance-enhancing effects and side effects of the various substances that are used for doping. Drug abuse in athletes should be addressed with preventive measures, education, motivational interviewing, and, when indicated, pharmacologic interventions. Keywords: doping, athletes, steroids, drug abuse, mental illness

The use of performance enhancing drugs among elite athletes has been in the headlines recently, particularly with Lance Armstrong's fall from grace and his admission about widespread doping. Many argue that the use of drugs confers an unfair advantage and is ultimately dangerous to the health of the athletes. Others, like Professor Shuster, argue that the use of drugs is no different from other techniques employed by athletes to boost their performance: swimmers shaving their body hair; skiers wearing sleek body armour; archers and shooters having laser eye surgery to improve their accuracy. Professor Shuster puts forward the provocative argument that since 'there is no acceptable proof (that) drugs improve competitive performance and their use is no different from accepted sports practice, banning them is wrong and immoral.' JW Devine argues the other side, that the use of performance enhancing drugs poses a 'significant risk to the health of athletes' and perhaps more importantly, 'threatens to undermine the very purpose of sport' by disrupting the 'balance of excellences'.
Full Text Available Realisation of sport activities always demanded certain conditions. Among those, sports facilities are certainly necessary. Since there were important changes in the process of training itself and successful performance, as well as, the results achieved by the sportsmen; there is a need for adequate sports facilities, that include whole variety of systems,equipment and necessities. Nowadays, Sport facilities are not only “the place of event”, but also a condition/necessity in achieving best sport results. It is demanded that these facilities are comfortable, absolutely secure and that they can accommodate transmissions: an opening, the course of sports activities and the announcement of the winner. The kind of sport activity, age, sex; so the “sports level” of the competitors is emphasising the specific demands to wards sports facilities.

There is growing concern about the poor quality and lack of repeatability of many pre-clinical experiments involving laboratory animals. According to one estimate as much as $28 billion is wasted annually in the USA alone in such studies. A decade ago the FDA's "Critical path" white paper noted that "The traditional tools used to assess product safety-animal toxicology and outcomes from human studies-have changed little over many decades and have largely not benefited from recent gains in scientific knowledge. The inability to better assess and predict product safety leads to failures during clinical development and, occasionally, after marketing." Repeat-dose 28-days and 90-days toxicity tests in rodents have been widely used as part of a strategy to assess the safety of drugs and chemicals but their repeatability and power to detect adverse effects have not been formally evaluated.The guidelines (OECD TG 407 and 408) for these tests specify the dose levels and number of animals per dose but do not specify the strain of animals which should be used. In practice, almost all the tests are done using genetically undefined "albino" rats or mice in which the genetic variation, a major cause of inter-individual and strain variability, is unknown and uncontrolled. This chapter suggests that a better strategy would be to use small numbers of animals of several genetically defined strains of mice or rats instead of the undefined animals used at present. Inbred strains are more stable providing more repeatable data than outbred stocks. Importantly their greater phenotypic uniformity should lead to more powerful and repeatable tests. Any observed strain differences would indicate genetic variation in response to the test substance, providing key data. We suggest that the FDA and other regulators and funding organizations should support research to evaluate this alternative.
Full Text Available The purpose of the study was to develop an aerobic fitness assessment test for competitive Karate practitioners and describe the preliminary findings. Five well-trained, competitive Karate practitioners participated in this study. A protocol simulating common attack strikes used in competition Karate sparring was developed from video analysis. In addition, pilot testing established a specific sequence of strikes and timings to be used in the test. The time to perform the strike sequence remained the same, whilst the time between strike sequence performances was progressively reduced. The aim of the test was to increase intensity of exercise through a decrease in recovery. On two separate occasions, absolute and relative peak oxygen uptake (VO2peak, peak ventilation (VEpeak, maximum heart rate (HRM, and time to exhaustion (TE obtained during the test were recorded. Subjective feedback provided by the participants was positive in that participants felt the test accurately simulated actions of a competitive sparring situation, and as a result athletes felt more motivated to perform well on this test. There was no significant between test difference in absolute VO2peak, relative VO2peak, HRM and TE (p > 0.05, indicating a potentially high reproducibility with the new test for these variables (test 1-test 2 difference of 0.04 L·min-1, 1 ml·kg-1·min-1, -3 beats·min-1, and 28 s; respectively. However, VEpeak displayed potentially less reproducibility due to a significant difference observed between tests (test 1- test 2 difference of -2.8 L·min-1, p < 0.05. There was a significant relationship between TE and relative VO2peak (R2 = 0.77, p < 0.001. Further developments to the test will need to address issues with work rate/force output assessment/monitoring. The new test accurately simulates the actions of competitive Karate sparring

Driving following illicit drug consumption ('drug-driving') is a potential road safety risk. Roadside drug testing (RDT) is conducted across Australia with the dual aims of prosecuting drivers with drugs in their system and deterring drug-driving. We examined trends over time in self-reported past six-month drug-driving among sentinel samples of regular drug users and assessed the impact of experiences of RDT on drug-driving among these participants. Data from 1913 people who inject drugs (PWID) and 3140 regular psychostimulant users (RPU) who were first-time participants in a series of repeat cross-sectional sentinel studies conducted in Australian capital cities from 2007 to 2013 and reported driving in the past six months were analysed. Trends over time were assessed using the χ 2 test for trend. Multivariable logistic regressions assessed the relationship between experiences of RDT and recent drug-driving, adjusting for survey year, jurisdiction of residence and socio-demographic and drug use characteristics. The percentage of participants reporting recent (past six months) drug-driving decreased significantly over time among both samples (PWID: 83%  vs. 74% , p<0.001; RPU: 72% vs. 56%, p<0.001), but drug-driving remained prevalent. Lifetime experience of RDT increased significantly over time (PWID: 6%  vs. 32% , p<0.001; RPU: 2% vs. 11%, p<0.001). There were no significant associations between experiencing RDT and drug-driving among either PWID or RPU. Although there is some evidence that drug-driving among key risk groups of regular drug users is declining in Australia, possibly reflecting a general deterrent effect of RDT, experiencing RDT appears to have no specific deterrent effect on drug-driving. Further intervention, with a particular focus on changing attitudes towards drug-driving, may be needed to further reduce this practice among these groups. Copyright © 2017 Elsevier Ltd.

To review home drug-testing products and the Internet-based recommendations intended for parents. A qualitative review of drug-testing products and structured analysis of information presented on company Internet sites were conducted. Eight Internet sites that sold home drug-testing products and contained a "parent's section" were identified by Ixquick using the search term "home drug testing." Description and prices of products sold by each Internet site and recommended indications for testing, consent, collection procedures, and follow-up of positive and negative test results were researched. A variety of drug-testing products were available, including breath and saliva tests for alcohol, a multidrug panel hair test, and a variety of laboratory and instant urine tests. Prices ranged from 2.75 dollars for a single alcohol test to 89.00 dollars for a multidrug combination urine/hair package. A total of 14 indications for home drug-testing were cited; all sites claimed that drug testing was a way to know with certainty whether a child has used drugs. Only 1 web site made a clear statement against testing an adolescent against his or her will. Little information was presented on valid specimen collection procedures and the risks of false-positive and false-negative tests. Only half of the sites recommended that parents consult a professional if a test is positive. Pediatricians should advise parents of the limitations and potential risks associated with home drug-testing products.

The liver is an important target for drug-induced toxicities. Early detection of hepatotoxic drugs requires use of well-characterized test systems, yet current knowledge, gaps and limitations of tests employed remains an important issue for drug development. Areas Covered: The current state of the science, understanding and application of test systems in use for the detection of drug-induced cytotoxicity, mitochondrial toxicity, cholestasis and inflammation is summarized. The test systems highlighted herein cover mostly in vitro and some in vivo models and endpoint measurements used in the assessment of small molecule toxic liabilities. Opportunities for research efforts in areas necessitating the development of specific tests and improved mechanistic understanding are highlighted. Expert Opinion: Use of in vitro test systems for safety optimization will remain a core activity in drug discovery. Substantial inroads have been made with a number of assays established for human Drug-induced Liver Injury. There nevertheless remain significant gaps with a need for improved in vitro tools and novel tests to address specific mechanisms of human Drug-Induced Liver Injury. Progress in these areas will necessitate not only models fit for application, but also mechanistic understanding of how chemical insult on the liver occurs in order to identify translational and quantifiable readouts for decision-making.

To conduct a systematic review of published literature on advanced neuroimaging, fluid biomarkers and genetic testing in the assessment of sport-related concussion (SRC). Computerised searches of Medline, PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycINFO, Scopus and Cochrane Library from 1 January 2000 to 31 December 2016 were done. There were 3222 articles identified. In addition to medical subject heading terms, a study was included if (1) published in English, (2) represented original research, (3) involved human research, (4) pertained to SRC and (5) involved data from neuroimaging, fluid biomarkers or genetic testing collected within 6 months of injury. Ninety-eight studies qualified for review (76 neuroimaging, 16 biomarkers and 6 genetic testing). Separate reviews were conducted for neuroimaging, biomarkers and genetic testing. A standardised data extraction tool was used to document study design, population, tests employed and key findings. Reviewers used a modified quality assessment of studies of diagnostic accuracy studies (QUADAS-2) tool to rate the risk of bias, and a modified Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system to rate the overall level of evidence for each search. Results from the three respective reviews are compiled in separate tables and an interpretive summary of the findings is provided. Advanced neuroimaging, fluid biomarkers and genetic testing are important research tools, but require further validation to determine their ultimate clinical utility in the evaluation of SRC. Future research efforts should address current gaps that limit clinical translation. Ultimately, research on neurobiological and genetic aspects of SRC is predicted to have major translational significance to evidence-based approaches to clinical management of SRC, much like applied clinical research has had over the past 20 years. © Article author(s) (or their employer(s) unless otherwise

Given the importance of ensuring athletes train and compete in a nonfatigued state, reliable tests are required to regularly monitor fatigue. The purpose of this study was to investigate the reliability of a cycle ergometer to measure peak power during short maximal sprint cycle efforts in running-based team sport athletes. Fourteen professional male Australian rules footballers performed a sprint cycle protocol during 3 separate trials, with each trial separated by 7 days. The protocol consisted of a standardized warm-up, a maximal 6-second sprint cycle effort, a 1-minute active recovery, and a second maximal 6-second sprint cycle effort. Peak power was recorded as the highest power output of the 2 sprint cycle efforts. Absolute peak power (mean ± SD) was 1502 ± 202, 1498 ± 191, and 1495 ± 210 W for trials 1, 2, and 3, respectively. The mean coefficient of variation, intraclass correlation coefficient, and SE of measurement for peak power between trials was 3.0% (90% confidence intervals [CIs] = 2.5-3.8%), 0.96 (90% CIs = 0.91-0.98), and 39 W, respectively. The smallest worthwhile change for relative peak power was 6.0%, which equated to 1.03 W·kg⁻¹. The cycle ergometer sprint test protocol described in this study is highly reliable in elite Australian rules footballers and can be used to track meaningful changes in performance over time, making it a potentially useful fatigue-monitoring tool.

Estimated base rates of invalid performance on baseline testing (base rates of failure) for the management of sport-related concussion range from 6.1% to 40.0%, depending on the validity indicator used. The instability of this key measure represents a challenge in the clinical interpretation of test results that could undermine the utility of baseline testing. To determine the prevalence of invalid performance on baseline testing and to assess whether the prevalence varies as a function of age and validity indicator. This retrospective, cross-sectional study included data collected between January 1, 2012, and December 31, 2016, from a clinical referral center in the Midwestern United States. Participants included 7897 consecutively tested, equivalently proportioned male and female athletes aged 10 to 21 years, who completed baseline neurocognitive testing for the purpose of concussion management. Baseline assessment was conducted with the Immediate Postconcussion Assessment and Cognitive Testing (ImPACT), a computerized neurocognitive test designed for assessment of concussion. Base rates of failure on published ImPACT validity indicators were compared within and across age groups. Hypotheses were developed after data collection but prior to analyses. Of the 7897 study participants, 4086 (51.7%) were male, mean (SD) age was 14.71 (1.78) years, 7820 (99.0%) were primarily English speaking, and the mean (SD) educational level was 8.79 (1.68) years. The base rate of failure ranged from 6.4% to 47.6% across individual indicators. Most of the sample (55.7%) failed at least 1 of 4 validity indicators. The base rate of failure varied considerably across age groups (117 of 140 [83.6%] for those aged 10 years to 14 of 48 [29.2%] for those aged 21 years), representing a risk ratio of 2.86 (95% CI, 2.60-3.16; P validity indicator and the age of the examinee. The strong age association, with 3 of 4 participants aged 10 to 12 years failing validity indicators, suggests that

Full Text Available One important tool for producing specifi c and individualized training intensities is to determine ventilatory threshold (VT, respiratory compensation point (RCP and maximal oxygen uptake (VO2max by means of maximum effort testing. However, in order to be able to interpret these data in a wide-ranging manner, it is also important to understand the metabolic responses that occur during the test as the systems transporting and utilizing O2 and producing CO2 adjust. This review article presents an overview of the metabolic responses that take place during a hypothetical maximum effort test, and the applicability of the fi gures thus obtained to the training of athletes. ABSTRACT A determinação das velocidades atingidas no limiar ventilatório (LV, ponto de compensação respiratório (PCR e consumo máximo de O2 (VO2max através de um teste de esforço máximo, é uma ferramenta importante para a aplicação de intensidades de treinamento específicas e individualizadas. Mas para poder interpretar os dados de uma forma abrangente, também é importante o entendimento das respostas metabólicas presentes no ajuste dos sistemas de transporte e utilização de O2 e produção de CO2 durante a realização do teste. Esta revisão apresenta um panorama das respostas metabólicas que acontecem durante a realização de um teste de esforço máximo hipotético, e a aplicabilidade dos valores obtidos no treinamento de atletas.

To explore women's attitudes and perceptions regarding legal requirements for prenatal drug testing. Web-based survey of 500 US women (age 18-45) recruited from a market research survey panel. A 24-item questionnaire assessed their opinion of laws requiring doctors to routinely verbal screen and urine drug test patients during pregnancy; recommendations for consequences for positive drug tests during pregnancy; and opinion of laws requiring routine drug testing of newborns. Additional questions asked participants about the influence of such laws on their own care-seeking behaviors. Data were analyzed for associations between participant characteristics and survey responses using Pearson's chi-squared test. The majority of respondents (86%) stated they would support a law requiring verbal screening of all pregnant patients and 73% would support a law requiring universal urine drug testing in pregnancy. Fewer respondents were willing to support laws that required verbal screening or urine drug testing (68% and 61%, respectively) targeting only Medicaid recipients. Twenty-one percent of respondents indicated they would be offended if their doctors asked them about drug use and 14% indicated that mandatory drug testing would discourage prenatal care attendance. Women would be more supportive of policies requiring universal rather than targeted screening and testing for prenatal drug use. However, a noteworthy proportion of women would be discouraged from attending prenatal care - a reminder that drug testing policies may have detrimental effects on maternal child health.

The aim of this study was to examine the neuropsychological test results of non-concussed high school athletes playing at three different levels of contact sports. Based on the concussion risk data of 12 different sports, a High Contact group (n=2819; wrestling/martial arts, cheerleading, track and field, football), a Moderate Contact group (n=2323; softball, basketball, soccer), and a Low Contact group (n=1580; baseball, volleyball, water polo, tennis, cross-country) were formed and compared in terms of their scores on the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT). The results revealed that the High Contact group obtained small but statistically poorer performances in ImPACT Visual Memory, Visual Motor Speed, Impulse Control, and Total Symptom scores compared to the Moderate and Low Contact groups. The High Contact group also had poorer Reaction Time scores compared to the Low Contact group. No differences between the Moderate and Low Contact groups were noted. The findings, along with prior similar results, tentatively raise concerns that participant in high contact sports, exposed to repetitive subconcussive head trauma, may be at greater risk for lowered neuropsychological functioning and increased symptoms, compared to other high school athletes. In view of the preliminary nature of this investigation, more research into the effects of frequent head impacts in high school sports is strongly recommended.

Caffeine is the most widely ingested psychoactive drug in the world. As many know, chronic use of caffeine leads to dependence, tolerance, drug craving, and upon abrupt cessation unpleasant withdrawal symptoms. Thus, caffeine fulfills pharmacological criteria by which agents are classified as drugs of abuse. Nevertheless, its use is legal and only at high, but readily attainable, levels is it banned from sport. Its use is widespread by athletes as young as 11 years of age who are seeking athletic advantage over fellow competitors. It is likely that its use will not decline any time soon because it is inexpensive, readily available, medically quite safe, socially acceptable, and by most measures legal. However, at levels allowed in sport, caffeine through its wide-ranging physiological and psychological effects increases endurance in well-trained athletes. If the goal of drug-testing and education programs in sport is to protect the health of athletes, prevent unfair advantage (cheating) and encourage ethical behavior then it seems obvious that the allowable levels of caffeine ingestion should be decreased. The alternative is to continue with policies designed largely to punish only those that get caught.

Full Text Available Over the past few years the analysis of drug residues in sewage has been promoted as a means of estimating the level of drug use in communities. Measured drug residue concentrations in the sewage are used to determine the load (total mass of the drug being used by the entire community. Knowledge of the size or population of the community then allows for the calculation of drug-use relative to population (typically drug-mass/day/1000 inhabitants which facilitates comparisons between differing communities or populations. Studies have been performed in many European countries, including Norway, as well as in the US and Australia. The approach has successfully estimated the use of cocaine, amphetamine, methamphetamine, MDMA, cannabis, nicotine and alcohol. The analysis of biomarkers of drug use in sewage has great potential to support and complement existing techniques for estimating levels of drug use, and as such has been identified as a promising development by the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA; www.emcdda.europa.eu/wastewater-analysis. The approach is not without its challenges, and ongoing collaboration across Europe aims at agreeing upon best-practice and harmonising the methods being used. In Norway development is being performed through the NFR RUSMIDDEL funded DrugMon (www.niva.no/drugmon project that has led to the development of many new techniques, significantly improved our understanding of the uncertainties associated with the approach and allowed the coordination of Europe wide collaboration which has included all important intercalibration exercises. Application of the technique can provide evidence-based and real-time estimates of collective drug use with the resulting data used to improve the much needed estimates of drug use and dependency.

Many patients with multiple medical problems who are receiving a variety of drugs are investigated with imaging techniques which require intravascular contrast media. The Contrast Media Safety Committee of the European Society of Urogenital Radiology therefore decided to review the literature and to draw up simple guidelines on interactions between contrast media and other drugs. An extensive literature search was carried out and summarized in a report. Based on the available information, simple guidelines have been drawn up. The report and guidelines were discussed at the 11th European Symposium on Urogenital Radiology in Santiago de Compostela. Contrast media may interact with other drugs, and may interfere with isotope studies and biochemical measurements. Awareness of the patient drug history is important to avoid potential hazards. Simple guidelines are presented. (orig.)

Rodríguez-Rosell, D, Mora-Custodio, R, Franco-Márquez, F, Yáñez-García, JM, González-Badillo, JJ. Traditional vs. sport-specific vertical jump tests: reliability, validity, and relationship with the legs strength and sprint performance in adult and teen soccer and basketball players. J Strength Cond Res 31(1): 196-206, 2017-The vertical jump is considered an essential motor skill in many team sports. Many protocols have been used to assess vertical jump ability. However, controversy regarding test selection still exists based on the reliability and specificity of the tests. The main aim of this study was to analyze the reliability and validity of 2 standardized (countermovement jump [CMJ] and Abalakov jump [AJ]) and 2 sport-specific (run-up with 2 [2-LEGS] or 1 leg [1-LEG] take-off jump) vertical jump tests, and their usefulness as predictors of sprint and strength performance for soccer (n = 127) and basketball (n = 59) players in 3 different categories (Under-15, Under-18, and Adults). Three attempts for each of the 4 jump tests were recorded. Twenty-meter sprint time and estimated 1 repetition maximum in full squat were also evaluated. All jump tests showed high intraclass correlation coefficients (0.969-0.995) and low coefficients of variation (1.54-4.82%), although 1-LEG was the jump test with the lowest absolute and relative reliability. All selected jump tests were significantly correlated (r = 0.580-0.983). Factor analysis resulted in the extraction of one principal component, which explained 82.90-95.79% of the variance of all jump tests. The 1-LEG test showed the lowest associations with sprint and strength performance. The results of this study suggest that CMJ and AJ are the most reliable tests for the estimation of explosive force in soccer and basketball players in different age categories.

This paper provides an overview of the ethical issues pertaining to the use of genetic insights and techniques in sport. Initially, it considers a range of scientific findings that have stimulated debate about the ethical issues associated with genetics applied to sport. It also outlines some of the early policy responses to these discoveries from world leading sports organizations, along with knowledge about actual use of gene technologies in sport. Subsequently, it considers the challenges with distinguishing between therapeutic use and human enhancement within genetic science, which is a particularly important issue for the world of sport. Next, particular attention is given to the use of genetic information, which raises questions about the legitimacy and reliability of genetic tests, along with the potential public value of having DNA databanks to economize in health care. Finally, the ethics of gene transfer are considered, inviting questions into the values of sport and humanity. It argues that, while gene modification may seem conceptually similar to other forms of doping, the requirements upon athletes are such that new forms of enhancement become increasingly necessary to discover. Insofar as genetic science is able to create safer, more effective techniques of human modification, then it may be an appealing route through which to modify athletes to safeguard the future of elite sports as enterprises of human excellence.

Some patients have adverse reactions to anti-tuberculosis drugs. We have reported that drug lymphocyte stimulation testing (DLST), which we performed at Week 1 of adverse reactions, provides little useful information (14.9% sensitivity). However, it remains unclear whether the time of performance of the DLST contributed to these results. Patients with adverse reactions to anti-tuberculosis drugs, including rash, hepatitis and fever, underwent DLST in the first week of the adverse reaction and were then randomly assigned to Group A (among whom a second DLST was performed 2 months after the reaction) or Group B (among whom a second DLST was performed >12 months after the reaction). We compared Group A with Group B to determine the optimal timing for the performance of DLST. The causative drug was identified by an oral drug provocation test. Consistent with the previous study, the sensitivity of DLST performed in the first week was low (14.3%). For DLST performed later, the sensitivity in Group A and Group B was respectively 5.0% and 6.7%. DLST is not useful for determining the causative drug in patients with rash, hepatitis or fever reactions to anti-tuberculosis drugs, regardless of when it is performed.

Sport-confidence is considered a critical success factor for sport performers at all levels. Researchers have suggested that sport-confidence is a multidimensional rather than a unidimensional construct, and the sport-confidence model identified three types of sport-confidence (i.e., physical skills and training, cognitive efficiency, and resilience) that are important for success in sport. However, such multidimensionality of sport-confidence and its measurement have not been fully examined. On a large sample of sport performers with varied skill levels and characteristics, the purpose of the present study was to examine the three-factor model of sport-confidence. We tested the measurement invariance of the Sport-Confidence Inventory across 512 athletes and 1170 non-athlete sport performers. Results from the multiple group model analysis showed that the three-factor model of sport-confidence fit better for the athlete sample than for the non-athlete sample. The results implicate that the three-factor model of sport-confidence model is suitable to athletes, though sport-confidence may appear more unidimensional for non-athletes. The use of the Sport-Confidence Inventory for non-athlete sport performers demands further consideration; however, the findings implicate that it could be a useful tool to assess sport-confidence of sport performers at any levels.

Fostering positive school climates and student drug testing have been separately proposed as strategies to reduce student drug use in high schools. To assess the promise of these strategies, the present research examined whether positive school climates and/or student drug testing successfully predicted changes in youth substance use over a 1-year follow-up. Two waves of panel data from a sample of 361 high school students, assessed 1 year apart, were analyzed. Changes in reported initiation and escalation in frequency of alcohol, cigarette, and marijuana use as a function of perceived student drug testing and positive school climates were analyzed, while we held constant prior substance use. Perceived student drug testing was not associated with changes in substance use, whereas perceived positive school climates were associated with a reduction in cigarette and marijuana initiation and a reduction in escalation of frequency of cigarette use at 1-year follow-up. However, perceived positive school climates were not associated with a reduction in alcohol use. Student drug testing appears to be less associated with substance use than positive school climates. Nevertheless, even favorable school climates may not be able to influence the use of alcohol, which appears to be quite normative in this age group.

The purpose of this investigation was to assess the number of test-retest trials required to familiarize participants in order to provide acceptable reliability for the measurement of an eye-hand coordination task using the Sport Vision Trainer (SVT). Two schedules were conducted (S1 and S2). For S1, 64 participants (male n = 51, age 20.8 ± 4.9 years; female n = 13, age 20.1 ± 2.1 years) attended four sessions each 1 week apart, and undertook four trials using the SVT. For S2, 60 participants (male n = 46, age 20.8 ± 4.9 years; female n = 14, age 20.1 ± 2.1 years) attended one 20-minute schedule consisting of four consecutive trials using the SVT. Limits of agreement (LoA) analyses showed that absolute reliability was increased in both studies. The LoA for S2 indicate that error decreased between trial 1-2, 2-3, and 3-4; ± 0.95 (CI, -1.16, +2.56sec), ± 0.97 (CI, -1.66, +2.14sec), ± 0.69 (CI, -1.08, +1.62sec). It was concluded that reliable measurements of eye-hand coordination can be obtained using the SVT in one session.

The purpose of this study was to identify if sport-specific and cardiopulmonary exercise testing differentiated professional from amateur soccer players. Thirty six men comprising 18 professional (mean±s: age 23.2±2.4 years) and 18 amateur (mean±SD: age 21.1±1.6 years) soccer players participated and performed four tests on separate occasions: 1) a graded exercise test to determine VO2max; 2) four exercise transients from walking to 80%Δ for the determination of VO2 kinetics; 3) the Yo-Yo Intermittent Recovery Test level 2 (Yo-Yo IR2) and 4) a repeated sprint test (RST). The players did not differ in VO2max (professional 56.5±2.9 mL.kg-1.min-1; amateur 55.7±3.5 mL.kg-1.min-1: P=0.484) or VO2 kinetic fundamental measures (τ1 onset, professional 24.5±3.2 s; amateur 24.0±1.8 s: τ1 cessation, professional 28.7±2.8 s; amateur 29.3±3.5 s: P=0.923). However, the amateurs were outperformed in the Yo-Yo IR2 (Professional 966±153 m; Amateur 840±156 m) (P=0.034) and RST (best time, professional 6.46±0.27 s; amateur 6.84±0.24 s, P=0.012). Performance indices derived from field-based sport-specific performance tests identified significant differences between professional and amateur players (P<0.05). However, neither tests of VO2 kinetics nor VO2max differentiated between groups, suggesting laboratory tests of cardiorespiratory parameters are probably less consequential to soccer than sport-specific field-based observations.

Recent guidelines advocate sports medicine professionals to use balance tests to assess sensorimotor status in the management of concussions. The present study sought to determine whether a low-cost balance board could provide a valid, reliable, and objective means of performing this balance testing. Criterion validity testing relative to a gold standard and 7 day test-retest reliability. University biomechanics laboratory. Thirty healthy young adults. Balance ability was assessed on 2 days separated by 1 week using (1) a gold standard measure (ie, scientific grade force plate), (2) a low-cost Nintendo Wii Balance Board (WBB), and (3) the Balance Error Scoring System (BESS). Validity of the WBB center of pressure path length and BESS scores were determined relative to the force plate data. Test-retest reliability was established based on intraclass correlation coefficients. Composite scores for the WBB had excellent validity (r = 0.99) and test-retest reliability (R = 0.88). Both the validity (r = 0.10-0.52) and test-retest reliability (r = 0.61-0.78) were lower for the BESS. These findings demonstrate that a low-cost balance board can provide improved balance testing accuracy/reliability compared with the BESS. This approach provides a potentially more valid/reliable, yet affordable, means of assessing sports-related concussion compared with current methods.
Full Text Available Introduction: During the last decade, the incidence of fungal infection has been increased in many countries. Because of the advent of resistant to antifungal agents, determination of an efficient strategic plan for treatment of fungal disease is an important issue in clinical mycology. Many methods have been introduced and developed for determination of invitro susceptibility tests. During the recent years, flow cytometry has developed to solving the problem and many papers have documented the usefulness of this technique. Materials and methods: As the first step, the invitro susceptibility of standard PTCC (Persian Type of Culture Collection strain and some clinical isolates of Candida consisting of Candida albicans, C. dubliniensis, C. glabrata, C. kefyer and C. parapsilosis were evaluated by macrodilution broth method according to NCCLS (National Committee for Clinical Laboratory Standards guidelines and flow cytometry susceptibility test. Results: The data indicated that macro dilution broth methods and flow cytometry have the same results in determination of MIC (Minimum Inhibitory Concentration for amphotericin B, clotrimazole, fluconazole, ketoconazole and miconazole in C. albicans PTCC 5027 as well as clinical Candida isolates, such as C.albicans, C.dubliniensis, C.glabrata C.kefyr, and C.parapsilosis. Discussion: Comparing the results obtained by macrodilution broth and flow cytometry methods revealed that flow cytometry was faster. It is suggested that flow cytometry susceptibility test can be used as a powerful tool for determination of MIC and administration of the best antifungal drug in treatment of patients with Candida infections.

In recent years, the abuse of opioid drugs has resulted in greater prevalence of addiction, overdose, and deaths attributable to opioid abuse. The epidemic of opioid abuse has prompted professional and government agencies to issue practice guidelines for prescribing opioids to manage chronic pain. An important tool available to providers is the drug test for use in the initial assessment of patients for possible opioid therapy, subsequent monitoring of compliance, and documentation of suspected aberrant drug behaviors. This review discusses the issues that most affect the clinical utility of drug testing in chronic pain management with opioid therapy. It focuses on the two most commonly used specimen matrices in drug testing: urine and oral fluid. The advantages and disadvantages of urine and oral fluid in the entire testing process, from specimen collection and analytical methodologies to result interpretation are reviewed. The analytical sensitivity and specificity limitations of immunoassays used for testing are examined in detail to draw attention to how these shortcomings can affect result interpretation and influence clinical decision-making in pain management. The need for specific identification and quantitative measurement of the drugs and metabolites present to investigate suspected aberrant drug behavior or unexpected positive results is analyzed. Also presented are recent developments in optimization of test menus and testing strategies, such as the modification of the standard screen and reflexed-confirmation testing model by eliminating some of the initial immunoassay-based tests and proceeding directly to definitive testing by mass spectrometry assays.

To present an overview and models of the potential causes and implications of sport-related hematuria in an athletic population as provided by a literature review. A total of 64 published scientific articles have been utilized to provide a review of sport-related hematuria. Reviewed studies were selected on the basis that they provided informative findings about the possible mechanisms of sport-related hematuria attributed to exercise duration and intensity. These studies used both normal adult and athletic populations. A review of the literature on the potential mechanisms of sport-related hematuria led to the classification of these mechanisms as either exercise duration related or exercise intensity related. Research has revealed an increased prevalence of hematuria in athletes. The mechanisms responsible may be traced to different sources or a combination thereof. Many explanations have been directed toward a potential cause; foot-strike hemolysis, renal ischemia, hypoxic damage to the kidney, the release of a hemolyzing factor, bladder and/or kidney trauma, nonsteroidal anti-inflammatory drugs, dehydration, increased circulation rate, myoglobinuria release, and the peroxidation of red blood cells. These mechanisms are presented in two models depicting the influence of either exercise intensity or exercise duration on sport-related hematuria. Athletes, coaches, and sports medicine professionals should be aware of this condition because frequent high-intensity and/or long-duration workouts and competitions may promote the symptoms. Repeated red blood cell loss through the urine may be a contributing factor toward promoting anemic conditions in competitive athletes. Recognition of the potential mechanisms can spare the time and expense of invasive testing.

To test an explanatory model of nurses' intention to report adverse drug reactions in hospital settings, based on the theory of planned behaviour. Under-reporting of adverse drug reactions is an important problem among nurses. A cross-sectional design was used. Data were collected with the adverse drug reporting nurses' questionnaire. Confirmatory factor analysis was performed to test the factor validity of the adverse drug reporting nurses' questionnaire, and structural equation modelling was used to test the explanatory model. The convenience sample comprised 500 Italian hospital nurses (mean age = 43.52). Confirmatory factor analysis supported the factor validity of the adverse drug reporting nurses' questionnaire. The structural equation modelling showed a good fit with the data. Nurses' intention to report adverse drug reactions was significantly predicted by attitudes, subjective norms and perceived behavioural control (R² = 0.16). The theory of planned behaviour effectively explained the mechanisms behind nurses' intention to report adverse drug reactions, showing how several factors come into play. In a scenario of organisational empowerment towards adverse drug reaction reporting, the major predictors of the intention to report are support for the decision to report adverse drug reactions from other health care practitioners, perceptions about the value of adverse drug reaction reporting and nurses' favourable self-assessment of their adverse drug reaction reporting skills. © 2017 John Wiley & Sons Ltd.

Full Text Available The control of the yield inside the process of sport training is one of the instruments that guarantee that it is made on the base of solid arguments as for the correspondence among the loads or preparation stimuli that must receive the sportsman and its condition to assimilate it. Due to the deficiencies, detected during a preliminary diagnosis based on the content analysis, measurement and mathematical statistical methods that corroborate the necessity to perfect elements of the sportsmen preparation management, a study begins with the in o rde r to give solution to the scientific problem: How to improve the pedagogic control of the legs force on Long and Middle distance, as well as Sport Walk athletes at 12 - 15 yeas school categories from “Ormani Arenado” Initial Sport School of Pinar del Río? It has the objective to select tests and indicators that improve this pedagogic control. There were used different methods and investigation instruments such as, analysis and synthesis, the measurement, as well as the descriptive and inferential statistic, which allowed the selection of the test of the ten jumps to include it in the protocol of evaluation of the physical performance set for the school categories, with procedures that brings forth four indicators on the sportsman's state. Its feasibility is being evaluating at present in an extended study certified by the provincial commission of Athletics. The contributions of this research, favor to the results of the investigative project “The evaluation and planning of the training in Long and Middle distance, as well as Sport Walk athletes in Pinar del Río”, answering, at the same time, to the fourth technological demand of the Athletics in this western county of Cuba.

Background Brazil recently approved synthetic phosphoetanolamine, a popularly dubbed 'cancer pill', a substance that has been shown to kill cancer cells in lab animal models but was not yet formally accessed in humans, and thus despite the existence of any evidence of its efficacy and safety. Methods The authors describe the recent decision of Brazil to aprove phosphoetanolamine in the context of growing 'judicialization' to promote access to medicines and thus reinforcing a growing sense of legal uncertainty. Results The approval of phosphoetanolamine despite the existence of any evidence of its efficacy and safety represents to the authors one of the saddest and surrealistic episodes in Brazil's recent public health history. Brazil's current economic crisis is fueling the 'judicialization' to promote access to medicines and thus reinforcing a growing sense of legal uncertainty in the context of rising economic constrains and a progressive failing state. The authors state that the Phosphoetanolamine's approval bill violates current legal prohibition of commercialisation of drugs without the Brazilian national drug regulatory agency's approval and thus may represent a potential menace to Brazil's pharmacogovernance and the country's governance to health technology assessment at the Brazilian national health systems. Conclusion Phosphoetanolamine's approval illustrates that the combination of flawed decision making, economic crisis and political interference may threaten weak governance mechanisms for drug regulation and health technology assessment and thus representing an extra burden in the sustainability of universal access-based national health systems.
To combat the rising use of drugs in the workplace many American companies have implemented drug testing programs and are testing employees and job applicants for use of illegal drugs. In addition, on September 15, 1986, Executive Order No.12564 was issued by President Reagan, which requires all federal agencies to develop programs and policies, one of the goals of which is to achieve a drug-free federal workplace. Included in this Executive Order is the requirement that federal agencies implement drug testing has become a prevalent practice as a means to detect and deter drug use in the workplace. Before a drug testing program is implemented, it is imperative that policies and procedures are developed that (1) ensure the accuracy of test results, (2) protect the validity and integrity of the specimen, (3) guarantee due process, and (4) maintain confidentiality. To make certain that these prerequisites were met in the government drug testing programs, the US Department of Health and Human Services (HHS) was directed to develop technical and scientific guidelines for conducting such programs. 15 refs., 1 fig., 2 tabs.

There are a lot of publications on the physical fitness of patients with haemophilia (PWH), however, most studies only reflect individual sport-specific motor capacities or focus on a single fitness ability. They involve small patient populations. In this respect principal objective of this study was to compare the physical fitness in all respects and the body composition of young PWH to healthy peers based on the most valid data we could get. Twenty-one German haemophilia treatment centres were visited from 2002 to 2009. PWH between 8 and 25 years were included. They performed a five-stage fitness test covering the sport-specific motor capacities for coordination, measured by one leg stand, strength, aerobic fitness and mobility as well as body composition. The patients' results were compared with age- and gender-specific reference values of healthy subjects. Two hundred and eighty-five PWH (mean age 13.2 ± 4.5 years, 164 PWH with severe disease) were included prospectively in the study. PWH are significantly below the reference values of healthy subjects in the one-leg stand test, the mobility of the lower extremity, the strength ratio of chest and back muscles and the endurance test. In body composition, the back strength and the mobility of the upper extremity PWH are significantly above the reference values. There are no significant differences in abdominal strength. In conclusion we found specific differences in different fitness abilities between PWH and healthy subjects. Knowing this, we are able to work out exercise programmes to compensate the diminished fitness abilities for our PWH. © 2015 John Wiley & Sons Ltd.

The impact of drug testing on the morale of mandatory participants was assessed through interviews and questionnaire responses of 500 intercollegiate athletes required to participate in a urine testing program. Subjects varied widely in their experiences. Most were not greatly affected, but some were embarrassed, humiliated, upset, and anxious about being inaccurately identified as drug users. Others experienced positive benefits: new information, a novel and interesting conversation piece, and a socially acceptable way to refuse drugs offered in friendship. Some said that testing benefited their athletic performance and school work. A number of recommendations were made to humanize and improve the experience: a better orientation about what to expect, more effective educational sessions, a warmer, more comfortable testing setting, more reasonable drug testing objectives, and more rigorous testing standards.

Recreational or regular physical and sport activities may be responsible for a wide range of cutaneous complications. Among them, "sports purpura" is a peculiar symptom that can occur during a large number of sports. "Effort purpura" defines any purpura occurring within the context of physical exercise irrespective of its cause. Therefore this clinical diagnosis includes various aetiologies. Diagnosis of traumatic purpura is often easy if the sport is mentioned in the anamnesis; cutaneous exercise - induced vasculitis must be also noted. Purpura can reveal systemic diseases or internal haemorrhage, such as spleen rupture, thrombopathies or systemic vasculitis, and other effort purpuras must be taken into account, including those related to the environment (cold, sun exposure...). Knowledge of a physical activity before the occurrence of purpura should be known by practitioner to avoid unnecessary and costly explorations in most of the cases.

The aim of this study is to estimate risky-drug use patterns of consumption of primary care patients. Multicentric descriptive cross-sectional study. five primary health care centers of the South of Madrid. all patients between 16-100 year-old consulting with their family physician. Spanish-validated World Health Organization ASSIST test was use to screen risky drug use in primary care. Total points scored at the test were obtained. A sum of 441 screening test were collected. Mean age was 51,3 years and 51.6% of patients presented a moderate-severe risky drug use out of the nine drugs tested. The more frequent drug use screened were tobacco (41.7%) followed by alcohol (15.4%), hypnotics (13.7%) and cannabis (5.7%). Differences were found between genders in the patterns: men had higher risky drug uses compared to women regarding alcohol and cannabis. Women had higher sedatives/hypnotics consumption prevalence. A 16% of patients presented with polyconsumption drug use patterns. There is risk derived from drug misuse in primary care for tobacco, alcohol, hypnotics and cannabis as detected by the ASSIST test. There is a higher rate of hypnotics than expected. Copyright © 2018 The Authors. Publicado por Elsevier España, S.L.U. All rights reserved.

The aim of this study was to evaluate psychometric properties of the Drug Use Disorders Identification Test (DUDIT) and the Drug Abuse Screening Test (DAST-10) in prisoners with (n = 124) or without (n = 78) drug use disorder. Participants were evaluated with the DUDIT, the DAST-10, and the Addiction Profile Index-Short (API-S). The DUDIT and the DAST-10 were found to be psychometrically sound drug abuse screening measures with high convergent validity when compared with each other (r = 0.86), and API-S (r = 0.88 and r = 0.84, respectively), and to have a Cronbach's α of 0.93 and 0.87, respectively. In addition, a single component accounted for 58.28% of total variance for DUDIT, whereas this was 47.10% for DAST-10. The DUDIT had sensitivity and specificity scores of 0.95 and 0.79, respectively, when using the optimal cut-off score of 10, whereas these scores were 0.88 and 0.74 for the DAST-10 when using the optimal cut-off score of 4. Additionally, both the DUDIT and the DAST-10 showed good discriminant validity as they differentiated prisoners with drug use disorder from those without. Findings support the Turkish versions of both the DUDIT and the DAST-10 as reliable and valid drug abuse screening instruments that measure unidimensional constructs.

Scientific focus on rugby has increased over the recent years, providing evidence of the physical or physiological characteristics and game-specific skills needed in the sport. Identification of tests commonly used to measure these characteristics is important for the development of test batteries, which in turn may be used for talent identification and injury prevention programmes. Although there are a number of tests available in the literature to measure physical or physiological variables and game-specific skills, there is limited information available on the psychometric properties of the tests. Therefore, the purpose of this study is to systematically review the literature for tests commonly used in rugby to measure physical or physiological characteristics and rugby-specific skills, documenting evidence of reliability and validity of the identified tests. A systematic review will be conducted. Electronic databases such as Scopus, MEDLINE via EBSCOhost and PubMed, Academic Search Premier, CINAHL and Africa-Wide Information via EBSCOhost will be searched for original research articles published in English from January 1, 1995, to December 31, 2015, using a pre-defined search strategy. The principal investigator will select potentially relevant articles from titles and abstracts. To minimise bias, full text of titles and abstracts deemed potentially relevant will be retrieved and reviewed by two independent reviewers based on the inclusion criteria. Data extraction will be conducted by the principal investigator and verified by two independent reviewers. The Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) checklist will be used to assess the methodological quality of the selected studies. Choosing an appropriate test to be included in the screening test battery should be based on sound psychometric properties of the test available. This systematic review will provide an overview of the tests commonly used in rugby union

Grounded in self-determination theory (Deci & Ryan, 1985) and the self-concordance model (Sheldon & Elliot, 1999), this study examined the motivational processes underlying goal striving in sport as well as the role of perceived coach autonomy support in the goal process. Structural equation modeling with a sample of 210 British athletes showed that autonomous goal motives positively predicted effort, which, in turn, predicted goal attainment. Goal attainment was positively linked to need satisfaction, which, in turn, predicted psychological well-being. Effort and need satisfaction were found to mediate the associations between autonomous motives and goal attainment and between attainment and well-being, respectively. Controlled motives negatively predicted well-being, and coach autonomy support positively predicted both autonomous motives and need satisfaction. Associations of autonomous motives with effort were not reducible to goal difficulty, goal specificity, or goal efficacy. These findings support the self-concordance model as a framework for further research on goal setting in sport.

Research adopting self-determination theory (SDT) supports a mediation model whereby coach motivational styles (autonomy support and interpersonal control) predict athletes' engagement and disaffection in youth sport via the satisfaction and frustration of psychological needs (autonomy, competence, and relatedness). Our study extends this research by examining SDT's mediation model longitudinally with three waves of data. Two hundred fifty-two youth sports participants (Mage = 12.98; SD = 1.84; range = 11-17; female n = 67) completed measures of study variables at the start, middle, and end of a competitive soccer season. Cross-lagged path analyses revealed that associations between the two coach motivational styles and athletes' engagement were mediated by psychological need satisfaction. Furthermore, a positive reciprocal association between psychological need satisfaction and engagement emerged over time. This study therefore supports the temporal assumptions underpinning SDT's mediation model but, importantly, evidences a mutually reinforcing interplay between athletes' psychological needs and their engaged behavior.

Full Text Available The papers deals with the application of the jump ergometer in the evaluation of neuromuscular performance. Altogether 288 athletes of different sport specializations (mean age 18.9 ± 6.4 years, height 172.2 ± 4.3 cm, and weight 62.4 ± 4.9 kg underwent various tests on the jump ergometer, such as 10-, 60-, and 90-second repeated jumps, squat and countermovement jumps without and with an additional load, and drop jumps from different heights with and without bending the knees. The diagnostic system FiTRO Jumper consisting of a special contact switch mattress connected by means of an interface to a computer was used. Jump parameters (power in the active phase of take off and height of the jump were calculated from the flight and contact times. Results showed that the system may be applied for the assessment of explosive power of the lower extremities, strength endurance of the lower extremities, utilization of the stretch shortening cycle, distribution of fast twitch fibers, optimal drop jump height for plyometric training, and training effects, namely in sports such as basketball, volleyball, soccer, tennis, gymnastics, rock and roll, figure skating, track and field, ski jumping, weight lifting, etc. Práce poukazuje na možnosti uplatnění výskokového ergometru při posuzovaní odrazových schopností dolních končetin.

The societal impact of drug use is well known. An example is when drug-intoxicated drivers increase the burden on policing and healthcare services. This work presents the correlation of wastewater analysis (using UHPLC-MS/MS) and positive roadside drug testing results for methamphetamine, 3,4-methylenedioxymethamphetamine (MDMA) and cannabis from December 2011-December 2016 in South Australia. Methamphetamine and MDMA showed similar trends between the data sources with matching increases and decreases, respectively. Cannabis was relatively steady based on wastewater analysis, but the roadside drug testing data started to diverge in the final part of the measurement period. The ability to triangulate data as shown here validates both wastewater analysis and roadside drug testing. This suggests that changes in overall population drug use revealed by WWA is consistent and proportional with changes in drug-driving behaviours. The results show that, at higher levels of drug use as measured by wastewater analysis, there is an increase in drug driving in the community and therefore more strain on health services and police.

To assess the effects of random drug and alcohol testing (DAT) among high school athletes. This was a 2-year prospective randomized controlled study of a single cohort among five intervention high schools with a DAT policy and six schools with a deferred policy, serially assessed by voluntary, confidential questionnaires. DAT school athletes were at risk for random testing during the full academic year. Positive test results were reported to parents or guardians, with mandatory counseling. Indices of illicit drug use, with and without alcohol use, were assessed at the beginning and end of each school year for the past month and prior year. Potential mediating variables were evaluated. Student-athletes from intervention and control schools did not differ in past 1-month use of illicit drug or a combination of drug and alcohol use at any of the four follow-up periods. At the end of the initial school year and after 2 full school years, student-athletes at DAT schools reported less drug use during the past year (p < .01) compared to athletes at the deferred policy schools. Combining past year drug and alcohol use together, student-athletes at DAT schools reported less use at the second and third follow-up assessments (p < .05). Paradoxically, DAT athletes across all assessments reported less athletic competence (p < .001), less belief authorities were opposed to drug use (p < .01), and indicated greater risk-taking (p < .05). At the final assessment, DAT athletes believed less in testing benefits (p < .05) and less that testing was a reason not to use drugs (p < .01). No DAT deterrent effects were evident for past month use during any of four follow-up periods. Prior-year drug use was reduced in two of four follow-up self-reports, and a combination of drug and alcohol use was reduced at two assessments as well. Overall, drug testing was accompanied by an increase in some risk factors for future substance use. More research is needed before DAT is considered an

Whenever athletes willfully or accidentally ingest performance-enhancing drugs or other banned substances (such as drugs of abuse), markers of those drugs can be detected in biological samples (e.g., biofluids: urine, saliva, blood); in the case of some drugs, that evidence can be apparent for many weeks following the last exposure to the drug. In addition to the willful use of prohibited drugs, athletes can accidentally ingest banned substances in contaminated dietary supplements or foods and inadvertently fail a drug test that could mean the end of an athletic career and the loss of a good reputation. The proliferation of performance-enhancing drugs and methods has required a corresponding increase in the analytical tools and methods required to identify the presence of banned substances in biofluids. Even though extraordinary steps have been taken by organizations such as the World Anti-Doping Agency to limit the use of prohibited substances and methods by athletes willing to cheat, it is apparent that some athletes continue to avoid detection by using alternative doping regimens or taking advantage of the limitations in testing methodologies. This article reviews the testing standards and analytical techniques underlying the procedures used to identify banned substances in biological samples, setting the stage for future summaries of the testing required to establish the use of steroids, stimulants, diuretics, and other prohibited substances.

Besides pathology endpoints, additional immune function endpoints have been included in the Note for Guidance on Repeated Dose Toxicity by the European Union (July 2001), which concern the analysis of antibody responses to a T-cell-dependent antigen. Guidance papers of other regulatory authorities are published as well. The main issue is the need for functional immunotoxicity testing to detect unintended immunosuppression. The International Conference on Harmonization (ICH) has surveyed studies from the files of the pharmaceutical industry to find the proportion of compounds that can be detected by additional immunotoxicity testing. Preliminary analysis shows that 10-15% of the compounds in the survey only react positively to the additional tests. More data are requested from the pharmaceutical industry. The Expert Working Group of the ICH has decided to choose a cause-for-concern approach to immmunotoxicity rather than a routine-screening approach.

In 2008 a Workplace Drug Testing (WDT) law became effective in Italy for workers involved in public/private transportation, oil/gas companies, and explosives/fireworks industry with the aim to ensure public safety for the community. To examine and elaborate WDT data collected on a large group of workers (over 43,500) during March 2009-February 2010 in order to highlight pros and cons and to draw suggestions for policies in the field. Northern Italy. After ≤ 24 h notification, workers provided a urine sample screened for opiates, methadone, buprenorphine, cocaine, amphetamines, ecstasy, and cannabinoids (THC) by immunoassay. Positives were confirmed by GC-MS. The positive rate was 2.0%, THC being most frequent drug (1.3%; cocaine, 0.4%; opioids, 0.3%). 6.9% of the positive workers tested positive for ≥ 2 classes (most often THC+cocaine). Gender ratio and mean age were significantly lower in positives (F/M=0.007; 35.5 ± 8.3 years) than negatives (0.016 and 40.7 ± 9.5, respectively). No decline in rates of positives and an increase of diluted samples over time were observed. The highest rates of positives were detected when sampling was performed just before/after week-end and during morning hours. Possible correlation between job type and drugs used were observed (e.g. more cocaine positives among road vehicle-drivers than among lift truck-drivers). Declared use of medicine/illicit drugs during the preceding week showed that illicit drug use was likely not always detected in urine and that almost 4% workers declared use of medicine drugs possibly affecting performance. This survey enabled to evidence relevant pitfalls of the law and to define strategies to improve the outcomes of WDT policies. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

Nurses and nursing students need good mathematics skills to do drug calculations correctly. As part of their undergraduate education, Norwegian nursing students must take a drug calculation test, obtaining no errors in the results. In spite of drug calculation tests, many adverse events occur, leading to a focus on drug administration skills both during students' courses and afterwards. Adverse events in drug administration can be related to poor mathematics skills education. The purpose of this study was to investigate the relationship between students' mathematics experiences in school (primary, secondary and high school) and their beliefs about being able to master the drug calculation test. A questionnaire was given to 116 first-year Bachelor of Nursing students. Those students who assessed their mathematics knowledge as poor found the requirement to obtain no errors in the drug calculation test more stressful than students who judged their mathematics knowledge as good. The youngest students were most likely to find the test requirement stressful. Teachers in high school had the most positive influence on mathematics interest, followed by teachers in secondary and primary school. Copyright © 2010 Elsevier Ltd. All rights reserved.

To evaluate practices in initial drug susceptibility testing (DST) in Moldova, anti-tuberculosis drug resistance and the implications for tuberculosis control. Retrospective record review in the national reference laboratory. Of 3463 cases, 57.1% were recorded as 'new' and 24.6% as 'retreatment' cases; previous treatment status was not recorded for 18.3%. Of the 'new' cases, 1655 were correctly classified according to international recommendations and 322 were misclassified. The number of cases increased from 443 in 1995 to 939 in 1999; the proportion of 'retreatment' increased from 17.4% to 35.5%, 'any drug resistance' from 20.3% to 41.6%, and 'multidrug resistance' from 2.7% to 11.2%. In 1998-1999, 'any drug resistance' and 'multidrug resistance' in 800 previously untreated cases were respectively 29.1% and 5.3%, and respectively 61.0% and 21.9% in 521 'retreatment' cases. Of a total of 216 'multidrug-resistant' cases in 1998-1999, 21.8% were reported resistant to ethambutol and 81.5% to streptomycin. Initial specimens for culture are frequently taken late, after the start of treatment, compromising their usefulness for case management or surveillance. Inadequate treatment has led to an increase in the number of cases, the proportion of previously treated cases and the prevalence of drug resistance. In 1998-1999, a high proportion of cases with 'multidrug resistance' were susceptible to ethambutol.

In order to ensure the quality of biomedical products, an experimental test for every single manufactured batch is required for many products. Especially in vaccine testing, animal experiments are traditionally used for this purpose. For example, efficacy is often determined via challenge experiments in laboratory animals. Safety tests of vaccine batches are also mostly performed using laboratory animals. However, many animal experiments have clear inherent disadvantages (low accuracy, questionable transferability to humans, unclear significance). Furthermore, for ethical reasons and animal welfare aspects animal experiments are also seen very critical by the public. Therefore, there is a strong trend towards replacing animal experiments with methods in which no animals are used ("replacement"). If a replacement is not possible, the required animal experiments should be improved in order to minimize the number of animals necessary ("reduction") and to reduce pain and suffering caused by the experiment to a minimum ("refinement"). This "3R concept" is meanwhile firmly established in legislature. In recent years many mandatory animal experiments have been replaced by alternative in vitro methods or improved according to the 3R principles; numerous alternative methods are currently under development. Nevertheless, the process from the development of a new method to its legal implementation takes a long time. Therefore, supplementary regulatory measures to facilitate validation and acceptance of new alternative methods could contribute to a faster and more consequent implementation of the 3R concept in the testing of biomedical products.

Purpose This study uses 14 years of data from nationally representative samples of US middle and high school students in the Monitoring the Future study to examine associations between school student drug testing (SDT), substance use, and participation in extracurricular activities. Methods Analyses use questionnaire data collected from 1998–2011 from 89,575 students in 883 middle schools and 157,400 students in 1,463 high schools to examine: (1) the current prevalence of SDT; (2) SDT trends over time; (3) associations between substance use and SDT type, volume, or duration among the general student population or students participating in activities subject to testing; (4) associations between students’ beliefs/attitudes about marijuana use and SDT; and (5) associations between extracurricular participation rates and SDT. Results Moderately lower marijuana use was associated with any random testing of the general high school student population and for SDT of middle and high school sub-populations specifically subject to testing (athletes or participants in non-athletic extracurricular activities). However, SDT generally was associated with increased use of illicit drugs other than marijuana. Conclusions Because the study design is observational and the data are cross-sectional, no strong causal conclusions can be drawn. However, there is evidence of lower marijuana use in the presence of SDT, and evidence of higher use of illicit drugs other than marijuana. Until further research can clarify the apparent opposing associations, schools should approach SDT with caution. PMID:23406889

The American Academy of Pediatrics continues to believe that adolescents should not be drug tested without their knowledge and consent. Recent US Supreme Court decisions and market forces have resulted in recommendations for drug testing of adolescents at school and products for parents to use to test adolescents at home. The American Academy of Pediatrics has strong reservations about testing adolescents at school or at home and believes that more research is needed on both safety and efficacy before school-based testing programs are implemented. The American Academy of Pediatrics also believes that more adolescent-specific substance abuse treatment resources are needed to ensure that testing leads to early rehabilitation rather than to punitive measures only.

Drug abuse has become a subject of concern to the oil and gas industry, where mistakes in the operation of large machines can result in injury, death and the loss of millions of dollars. Pre-employment urine tests are becoming standard procedure in the oil field. Many supervisors refuse to let employees start work without a clear test. Urine samples are tested for the presence of cannabis, cocaine, opiates, amphetamines and phencyclidine. When a worker is injured or killed on the job, or after an uncommon error that causes significant damage, all parties involved are tested as soon as possible and a receipt of the results are expedited. The Alberta Human Rights and Citizenship Commission is now addressing the issue of drug testing, and has ascertained that drug and alcohol testing are only allowable in certain circumstances, and that it is discriminatory to test potential or existing employees for drug and alcohol use if the testing is not reasonable or justifiable. They have also suggested that there is a duty to accommodate persons with disabilities in the workplace. Drug and alcohol dependency fall within the meaning of disabled. Under the Construction Owner's Association of Alberta's Canadian Model for a Safe Workplace, testing must work in concert with treatment. Current employees are directed to seek help via an employee assistant plan. Workers and supervisors report that drug use is rampant in work camps. Industry-wide, fail rates for those who take part in drug testing are quoted by experts as ranging from between 2 to 14 per cent. 2 figs.

Drug patch tests (DPTs) with medicaments suspected of causing an allergic reaction represent a method of diagnostic testing that is low risk; DPTs can reproduce delayed hypersensitivity to drugs, and entail only a moderate re-exposure of patients to potential offending drugs. We assessed the non-irritating concentrations of DPTs and determined the amounts of active ingredient (AI) contained in the drugs used in the tests. The objectives were to assess the non-irritating concentration of DPTs and determine the amounts of active ingredient (AI) contained in the drugs used in the tests. From a retrospective, single-centre study of all patients investigated during a 6-year period with a drug eruption, each potentially responsible drug was tested with the commercially available preparation diluted to 30% in water, petrolatum, or alcohol. Data collection was performed with a customized computer database. For each type of DPT studied, the numbers of positive and negative test results were recorded. The amount of AI contained in the DPT (as a percentage) was then calculated after weighing of each tablet. Of the 5558 DPTs studied, all were non-irritant. The average concentration of AI was 9.8%; 25% of DPTs had an AI concentration of concentration of > 16%. The AI concentration ranged from 0.05% (digoxin) to 30% (paracetamol lyophilisate). These data provide thresholds for the non-irritating concentration of AI of 68 different drugs, and thresholds for the non-irritating dilution for 82 drugs, and will help to standardize DPT methods. © 2014 John Wiley & Sons A/S.

Full Text Available The discovery of new drugs requires the development of improved animal models for drug testing. The Chinese tree shrew is considered to be a realistic candidate model. To assess the potential of the Chinese tree shrew for pharmacological testing, we performed drug target prediction and analysis on genomic and transcriptomic scales. Using our pipeline, 3,482 proteins were predicted to be drug targets. Of these predicted targets, 446 and 1,049 proteins with the highest rank and total scores, respectively, included homologs of targets for cancer chemotherapy, depression, age-related decline and cardiovascular disease. Based on comparative analyses, more than half of drug target proteins identified from the tree shrew genome were shown to be higher similarity to human targets than in the mouse. Target validation also demonstrated that the constitutive expression of the proteinase-activated receptors of tree shrew platelets is similar to that of human platelets but differs from that of mouse platelets. We developed an effective pipeline and search strategy for drug target prediction and the evaluation of model-based target identification for drug testing. This work provides useful information for future studies of the Chinese tree shrew as a source of novel targets for drug discovery research.

If the drugs are intended for delivery to humans, the most appropriate setting in which to do the assessment is the in vivo human. However, this may not be possible for ethical, practical, or economic reasons, particularly in the early phases of development. It is thus necessary to find alternative methods using accessible and reproducible surrogates for in vivo human skin. A range of models has been developed, including ex vivo human skin, usually obtained from cadavers or plastic surgery patients, ex vivo animal skin, and artificial or reconstructed skin models. Increasingly, largely driven by regulatory authorities and industry, there is a focus on developing standardized techniques and protocols. With this comes the need to demonstrate that the surrogate models produce results that correlate with those from in vivo human studies and that they can be used to show bioequivalence of different topical products. This review discusses the alternative skin models that have been developed as surrogates for normal and diseased skin and examines the concepts of using model systems for in vitro–in vivo correlation and the demonstration of bioequivalence. Keywords: percutaneous permeation, dermal delivery, transdermal, bioequivalence, ex vivo skin models, reconstructed skin

Bisphosphonates are a commonly used class of drugs with known efficacy in the prevention and treatment of postmenopausal and steroid-induced osteoporosis, Paget's disease of bone, hypercaelcemia of malignancy, osteolytic lesions of multiple myeloma, and bone metastases. Nitrogen-containing bisphosphonates have a favourable tolerability and safety profile, cutaneous reactions have been reported. This is a retrospective case series study, based on the analysis of data from 1429 patients admitted to the Allergy and Clinical Immunology Division of the University of Messina between January 2011 and December 2012. Most patients had previous adverse drug reactions (ADRs) and referred to us for a challenge test with an alternative drug. We observed six patients with a past history of adverse drug reaction who needed to be tested for bisphosphonates: three patients for risedronate, two for clodronate and one for alendronate. In two years only two patients were referred to us for an adverse reaction to bisphosphonates: one to alendronate and one to risedronate. Another patient presented a previous reaction to strontium ranelate. The other three patients reported previous hypersensitivity reactions to at least two different classes of drugs. All the patients experienced no reaction using the tested drugs. In our experience drug challenge tests for bisphosphonates are safe and reliable. Copyright © 2013 SEICAP.

Full Text Available It was the purpose of this preliminary project to measure how individuals perceive the impacts of sport in such areas as the economy, the environment, culture, community image and the quality of life, among other areas. The instrument was initially field tested in 1999 with a sample of 702 residents in the North eastern part of the United States. Their views suggest that they perceive sports to make a generally positive contribution to their communities and the local region. Some negative impacts were also identified, mostly of an environmental nature. However, the findings suggest that sports for the most part are perceived to play a major role in the lives of people and contribute in significant ways to the economy, and community pride.

A total of 106 isolates of Mycobacterium tuberculosis were tested for drug susceptibility by the conventional 7H11 plate method and by a new rapid radiometric method using special 7H12 liquid medium with 14 C-labeled substrate. Results obtained by the two methods were compared for rapidity, sensitivity, and specificity of the new test method. There was 98% overall agreement between the results obtained by the two methods. Of a total of 424 drug tests, only 8 drug results did not agree, mostly in the case of streptomycin. This new procedure was found to be rapid, with 87% of the tests results reportable within 4 days and 98% reportable within 5 days as compared to the usual 3 weeks required with the conventional indirect susceptibility test method. The results of this preliminary study indicate that the rapid radiometric method seems to have the potential for routine laboratory use and merits further investigations

Full Text Available As participation in both amateur and professional sports increases, so does the importance of sports performance and the factors influencing it. Determinants of success in sports can be classified as training, genetic, epigenetic, dietary, motivational, equipment and other environmental factors. The effect of genetics on sports performance and skill has been examined for many years. Autosomal genes, mitochondrial DNA and various genes located in the Y chromosome have all been associated with sports performance. It is not possible to link physical performance to a single genetic polymorphism. Genes that have been most extensively studied in their relation to performance include ACE, ACTN3, ADRA2A, ADRB2, PPARA, PPARGC1A, AMPD1, HIF1A, NOS3, BDKRB2, VEGFR2 and VEGFA. For the time being, genetic screening tests may be useful in determining the weaknesses and strengths of a sportsperson, but not in predicting athletic success.
Full Text Available Drug and alcohol abuse in the workplace represents a great risk to employee’s health and safety. More than 50% of the employees worldwide are related to easily accessible drug abuse, while 70% of the employees are related to alcohol abuse in the workplace. Tests for detecting drug and alcohol abuse in the workplace should be part of a new regulation, compulsory for all employees in the Republic of Macedonia. Implementing this sort of testing program should at the same time be a step towards devising particular solutions that shall bring about greater safety in the working environment. A key element in the implementation is to devise and establish an adequate policy that shall determine the risk factors within a working establishment which shall clearly express its position regarding drug and alcohol abuse during working hours. Along with the risk factors, the policy may also include the program for testing both, employees and the ones who are about to be employed, for drug and alcohol abuse. In order to implement this sort of test, it must be in accordance with the Occupational Safety and Health Act (Official gazette of the Republic of Macedonia, No 92/07, 2007 and a legal framework has to be defined, that shall regulate and solve numerous aspects of this issue, in order to fully implement the program for drug free working environment pursuant to the Declaration and the decrees of the United Nations General Assembly in 1998.

Pharmaceutical products are rigorously tested for safety and efficacy prior to being licensed for use. During this testing process the archetypal research subject is a young male; women and older people are less frequently invited to participate. This is especially true at the early stages, but can also occur in the later phases of drug testing. This paper considers the reasons for the relative under-representation of these groups, and the legal implications of failing to include as research subjects the very types of people who will ultimately consume these drugs.

Caster Semenya won the eight-hundred-meter title in the Berlin World Athletics Championships in 2009. Few hours after, Caster was at the center of a harsh contestation on gender. The International Association of Athletics Federations started an investigation, which was not respectful of her privacy. Caster's case highlights the need for an improvement in the awareness of genetic counseling principles amongst professionals, the public and various stakeholders. We critically examine the historical steps of gender verification in the Olympics, the violation of genetic counseling principles in Caster's case and outline some reflections on the complexity of the genetics of Disorders of sex development (DSD). Variability in both genotypes and phenotypes in DSD may not allow any etiological or functional classification at this point in time that could permit uncontroversial gender verification for fairer sport participation. We strongly suggest revisiting the pertinence of gender verification, and the process whereby this is done.

Since early 2000, intensive policing, wide scale street drug testing, and actions aimed at limiting the availability of specific drugs have been implemented in Georgia. Supporters of this approach argue that fear of drug testing and resulting punishment compels drug users to stop using and prevents youth from initiating drug use. It has been also stated that reduction in the availability of specific drugs should be seen as an indication of the overall success of counter-drug efforts. The aim of the current review is to describe the drug-related law enforcement response in Georgia and its impact on illicit drug consumption and drug-related harm. We reviewed relevant literature that included peer-reviewed scientific articles, stand-alone research reports, annual drug situation reports, technical reports and program data. This was also supplemented by the review of relevant legislation and judicial practices for the twelve year period between 2002 and 2014. Every episode of reduced availability of any "traditional" injection drug was followed by the discovery/introduction of a new injection preparation. The pattern of drug consumption was normally driven by users' attempts to substitute their drug of choice through mixing together available alternative substances. Chaotic poly-substance use and extensive utilization of home-made injection drugs, prepared from toxic precursors, became common. Massive random street drug testing had little or no effect on the prevalence of problem drug use. Intensive harassment of drug users and exclusive focus on reducing the availability of specific drugs did not result in reduction of the prevalence of injecting drug use. Repressive response of Georgian anti-drug authorities relied heavily on consumer sanctions, which led to shifts in drug users' behavior. In most cases, these shifts were associated with the introduction and use of new toxic preparations and subsequent harm to the physical and mental health of drug consumers.

The study tested utility of self-determination and sport commitment theories to understanding young athletes' sport commitment. 343 young athletes (M= 13.5 yr., SD= +/- 1.1) from soccer, basketball, volleyball, handball, and water polo teams volunteered to participate. All completed the Sport Motivation Scale and the Sport Commitment Questionnaire. Pearson correlations showed a strong relationship between commitment and intrinsic motivation scores. In contrast, extrinsic motivation scores were not significantly correlated to commitment, whereas amotivation scores showed a negative correlation to commitment. Path analysis resulted in strong positive association of intrinsic motivation and commitment. Amotivation had small negative relation to commitment. According to the model tested, social constraints and involvement opportunities were not significant contributors to sport commitment. An alternative model supported the mediating role of enjoyment to psychological commitment. The results showed that high self-determination is supportive of sport commitment, whereas low self-determination reduces sport commitment.

Hundreds of new psychoactive substances (NPS) have emerged in the drug market over the last decade. Few drug surveys in the USA, however, ask about use of NPS, so prevalence and correlates of use are largely unknown. A large portion of NPS use is unintentional or unknown as NPS are common adulterants in drugs like ecstasy/Molly, and most NPS are rapidly eliminated from the body, limiting efficacy of urine, blood and saliva testing. We utilized a novel method of examining prevalence of NPS use in a high-risk population utilizing hair-testing. Hair samples from high-risk nightclub and dance music attendees were tested for 82 drugs and metabolites (including NPS) using ultra-high performance liquid chromatography-tandem mass spectrometry. Eighty samples collected from different parts of the body were analyzed, 57 of which detected positive for at least one substance-either a traditional or new drug. Among these, 26 samples tested positive for at least one NPS-the most common being butylone (25 samples). Other new drugs detected include methylone, methoxetamine, 5/6-APB, α-PVP and 4-FA. Hair analysis proved a powerful tool to gain objective biological drug-prevalence information, free from possible biases of unintentional or unknown intake and untruthful reporting of use. Such testing can be used actively or retrospectively to validate survey responses and inform research on consumption patterns, including intentional and unknown use, polydrug-use, occasional NPS intake and frequent or heavy use. © The Author 2017.

In a paper arising out of an informal international consultation of specialists in the bacteriology of tuberculosis held in 1961, an attempt was made to formulate criteria, and specify technical procedures, for reliable tests of sensitivity (the absolute-concentration method, the resistance-ratio method and the proportion method) to the 3 main antituberculosis drugs (isoniazid, streptomycin and p-aminosalicylic acid). Seven years later, a further consultation was held to review the latest developments in the field and to suggest how sensitivity tests might be put to practical use in tuberculosis control programmes. The participants reached agreement on how to define drug sensitivity and resistance, and stressed the importance of using a discrimination approach to the calibration of sensitivity tests. Their views are contained in the present paper, which also includes descriptions of the sensitivity tests used by the Medical Research Council of Great Britain for first- and second-line drugs (minimal inhibitory concentration and resistance-ratio methods), the two main variants of the proportion method developed by the Institut Pasteur, Paris, and a method for calibrating sensitivity tests.

This study aimed to determine design features of a drug-checking service that would be feasible, attractive and likely to be used by Australian festival and nightlife attendees. Web survey of 851 Australians reporting use of psychostimulants and/or hallucinogens and attendance at licensed venues past midnight and/or festivals in the past year (70% male; median age 23 years). A drug-checking service located at festivals or clubs would be used by 94%; a fixed-site service external to such events by 85%. Most (80%) were willing to wait an hour for their result. Almost all (94%) would not use a service if there was a possibility of arrest, and a majority (64%) would not use a service that did not provide individual feedback of results. Drug-checking results were only slightly more attractive if they provided comprehensive quantitative results compared with qualitative results of key ingredients. Most (93%) were willing to pay up to $5, and 68% up to $10, per test. One-third (33%) reported willingness to donate a whole dose for testing: they were more likely to be male, younger, less experienced, use drugs more frequently and attend venues/festivals less frequently. In this sample, festival- or club-based drug-checking services with low wait times and low cost appear broadly attractive under conditions of legal amnesty and individualised feedback. Quantitative analysis of ecstasy pills requiring surrender of a whole pill may appeal to a minority in Australia where pills are more expensive than elsewhere.

Non-disclosure of drug use on surveys is common and many drug users unknowingly ingest adulterant or replacement drugs, which leads to underreporting of use of these drugs. Biological testing can complement survey research, and hair-testing is an appealing method as many drugs are detectable for months post-use. We examined willingness to donate a hair sample to be tested among those surveyed in a population at high risk for consuming adulterated drugs-electronic dance music (EDM) party attendees. We surveyed 933 adults entering EDM parties in New York City in 2017. Hair donation response rates and reasons for refusal were examined from this cross-sectional study. A third (n = 312; 33.4%) provided a hair sample. Lack of interest (21.0%), lack of time (19.8%), not wanting a lock of hair cut (17.7%), and disinterest in having hair cut in public (13.8%) were the main reported reasons for refusal. 4.7% refused because they could not receive results. Past-year drug users were more likely to fear identification than non-users (p<.001). Asian participants were at lower odds of providing a hair sample (aOR = 0.53, 95% CI = 0.32-0.87), and those reporting past-year use of LSD (aOR = 1.62, 95% CI = 1.11-2.35), opioids (nonmedical; aOR = 1.93, 95% CI = 1.25-2.99), and/or methamphetamine (aOR = 3.43, 95% CI = 1.36-8.62) were at higher odds of providing a sample than non-users of these drugs. Only a third of participants provided a hair sample and we found individual-level differences regarding willingness to provide a sample. Factors contributing to refusal should be considered to increase response rates and generalizability of results.

This study examined General Practitioner's (GP) knowledge, practice and training requirements in relation to doping in sport in Ireland. All 2083 GPs on the Irish College of General Practitioners (ICGP) register received a postal questionnaire, yielding a 37% response rate (N=771, 63% male, average age 46.2 +/- 9SD, range 28-74 years). Results revealed that 14% (112) deemed their knowledge of doping agents to be good or very good, 12% (94) had completed specific training modules in doping or sport, and 24% (183) were connected with a specific sport as a team doctor/advisor. Over one in four (28%: 217) had been consulted for advice on doping in Sport, 33% (256) possessed the current list of prohibited substances, and 25% (190) knew of the Irish Sports Council's drug-testing procedures. The current initiatives to discourage doping in sport were felt to be ineffective, and although 92% (716) indicated that GPs had a role to play in the prevention of doping in sport, only 9% (66) felt adequately trained for such a role. There was overwhelming support for further training among GPs, although the most appropriate method of providing training is complex and requires strategic planning.
Conclusion: We suggest drug susceptibility testing for more nontuberculous mycobateria, particularly M. avium complex isolated from infected birds and humans, as well as molecular basics of drug sensitivity in order to detect resistance genes of pathogenic M. avium subsp. avium.

Drug abuse is highly correlated with criminal behavior. The typical drug-using criminal commits hundreds of crimes per year. The crime rate cannot be significantly reduced without a reduction in the percentage of the population abusing drugs and alcohol. Accurate and timely estimation of that percentage is important for policy decisions concerning crime control, public health measures, allocation of intervention resources for prevention and treatment, projections of criminal justice needs, and the evaluation of policy effectiveness. Such estimation is particularly difficult because self reporting is unreliable; and physical testing has to date required blood or urine analysis which is expensive and invasive, with the result that too few people are tested. MIKOS Ltd. has developed a non-contact, passive technique with the potential for automatic, real- time screening for drug and alcohol use. The system utilizes thermal radiation which is spontaneously and continuously emitted by the human body. Facial thermal patterns and changes in patterns are correlated with standardized effects of specific drugs and alcohol. A portable system incorporating the collection and analysis technique can be used episodically to collect data for estimating drug and alcohol use by general unknown populations such as crowds at airports, or it can be used for repetitive routine screening of specific known groups such as airline pilots, military personnel, school children, or persons on probation or parole.

Even the finest state-of-the art preclinical drug testing, usually in primary hepatocytes, remains an imperfect science. Drugs continue to be withdrawn from the market due to unforeseen toxicity, side effects, and drug interactions. The space program may be able to provide a lifeline. Best known for rockets, space shuttles, astronauts and engineering, the space program has also delivered some serious medical science. Optimized suspension culture in NASA's specialized suspension culture devices, known as rotating wall vessels, uniquely maintains Phase I and Phase II drug metabolizing pathways in hepatocytes for weeks in cell culture. Previously prohibitively expensive, new materials and 3D printing techniques have the potential to make the NASA rotating wall vessel available inexpensively on an industrial scale. Here we address the tradeoffs inherent in the rotating wall vessel, limitations of alternative approaches for drug metabolism studies, and the market to be addressed. Better pre-clinical drug testing has the potential to significantly reduce the morbidity and mortality of one of the most common problems in modern medicine: adverse events related to pharmaceuticals.
Full Text Available Many laboratories validate DST of the second-line drugs by BACTEC MGIT 960 system. The objective of this study is to evaluate the critical concentration and perform DST for the 2nd line drugs. We evaluated 193 clinical strains of M. tuberculosis isolated from patients in South Korea. Testing the critical concentration of six second-line drugs was performed by MGIT 960 and compared with L-J proportion method. The critical concentration was determined to establish the most one that gave the difference between drug resistance and susceptibility in MGIT960 system. Good agreement of the following concentrations was found: Concordance was 95% for 0.5 μg/mL of moxifloxacin; 93.6%, 1.0 μg/mL of levofloxacin; 97.5%, 2.5 μg/mL of kanamycin; 90.6%, 2.5 μg/mL of capreomycin; 86.2%, 5.0 μg/mL of ethionamide; and 90.8%, 2.0 μg/mL of ρ-aminosalicylic acid. The critical concentrations of the four drugs, moxifloxacin, levofloxacin, kanamycin, and capreomycin, were concordant and reliable for testing 2nd line drug resistance. Further study of ethionamide and ρ-aminosalicylic acid is required.

Antimicrobial susceptibility testing (AST) is commonly used for determining microbial drug resistance, but routine testing, which can significantly reduce the spread of multi-drug resistant organisms, is not regularly performed in resource-limited and field-settings due to technological challenges and lack of trained diagnosticians. We developed a portable cost-effective smartphone-based colorimetric 96-well microtiter plate (MTP) reader capable of automated AST without the need for a trained diagnostician. This system is composed of a smartphone used in conjunction with a 3D-printed opto-mechanical attachment, which holds a set of inexpensive light-emitting-diodes and fiber-optic cables coupled to the 96-well MTP for enabling the capture of the transmitted light through each well by the smartphone camera. Images of the MTP plate are captured at multiple exposures and uploaded to a local or remote server (e.g., a laptop) for automated processing/analysis of the results using a custom-designed smartphone application. Each set of images are combined to generate a high dynamic-range image and analyzed for well turbidity (indicative of bacterial growth), followed by interpretative analysis per plate to determine minimum inhibitory concentration (MIC) and drug susceptibility for the specific bacterium. Results are returned to the originating device within 1 minute and shown to the user in tabular form. We demonstrated the capability of this platform using MTPs prepared with 17 antibiotic drugs targeting Gram-negative bacteria and tested 82 patient isolate MTPs of Klebsiella pneumoniae, achieving well turbidity accuracy of 98.19%, MIC accuracy of 95.15%, and drug susceptibility interpretation accuracy of 99.06%, meeting the FDA defined criteria for AST.

The drug provocation test (DPT) is the gold standard to rule out drug hypersensitivity. There are standardized DPT protocols to diagnose immediate reactions to drugs, but not for nonimmediate reactions. The aim of this study was to show the sensitivity and specificity of an allergy work-up that included a 5-day DPT in children with histories of nonimmediate reactions to amoxicillin through focusing on a pediatric population with histories of immediate and nonimmediate reactions to amoxicillin. Two hundred consecutive patients with histories of amoxicillin reactions referred to the Allergy Unit of Anna Meyer Children's Hospital for suspected drug allergy from 2008 to 2011 underwent in vivo tests with the culprit drug according to European Academy of Allergy and Clinical Immunology guidelines. Moreover, most of those children, regardless of the skin tests results, were challenged with amoxicillin for a total of 5 days. In 4 years, 200 patients were evaluated for a history of drug hypersensitivity to amoxicillin. The majority of patients (76%) had a history of mild nonimmediate reactions. All 200 patients underwent skin tests, and 9 of 200 tested positive. A total of 177 DPTs were performed with amoxicillin for 5 days in each child. Diagnosis of amoxicillin allergy was confirmed by a DPT in 17 patients (9.6%); 14/17 had history of nonimmediate reactions; 4/14 (26.6%) reacted on day 5. According to our results, a long-term DPT protocol increases the sensitivity of the allergy work-up, and it should be recommended for patients with a history of amoxicillin nonimmediate reaction.
