Castillo, D, Castagna, C, Cámara, J, Iturricastillo, A, and Yanci, J. Influence of team's rank on soccer referees' external and internal match loads during official matches. J Strength Cond Res 32(6): 1715-1722, 2018-The aim was to examine the external and the internal match loads (ML) of field referees (FRs) attending teams of different ranking during championship matches. Twenty FR who officiated in 30 official soccer matches (30 observations) participated in our study. The criteria for allocating the soccer referees' ML results were based on the teams' final league positions as follows: matches performed by Top 10 teams (TOP10), matches performed by bottom 10 teams (BOT10), and matches played among TOP10 and BOT10 teams (MIXED)...

AIM: We review clinical evidence of therapeutic efficacy and effectiveness of omega-3 fatty acids (omega-3s) in keratoconjunctivitis sicca, colloquially known as dry eye disease. In doing so, we identify relevant literature to address the following questions: 1) What definitive guidance can clinical evidence offer eye physicians and their patients? 2) What aspects of omega-3 supplementation lack definitive evidence, and how might economic assessments help? METHODS: A targeted and systematic search strategy based on PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) was designed in this study for refereed clinical trials of omega-3s in dry eye treatment...

These comments focus on the thermoluminescence aspect of the paper by Siti Rozaila et al, in particular the poor calibration of the TL dosimeters; not taking account of dark current signal; an incorrect method of measuring the fading factor and an incorrect method of correcting for fading of the TL signal. 
 An opinion is expressed that the paper has not been refereed adequately.

BACKGROUND: Elite athletes need to optimise their body composition to deliver world class performances and this argument could be extended to elite referees as well. Unfortunately, there is a scarcity of body composition information among football referees. AIM: The aim of the study was to determine and compare the body composition and somatotypes of male football referees and assistant referees who officiated in the 2013 Zimbabwe Premier Football League. METHODS: Forty-one participants (21 referees, 20 assistant referees; 8 FIFA, 33 ZIFA licenced referees) with a mean age of 34...

PURPOSE: To examine the movement and physiological demands of rugby union officiating within elite competition. METHODS: Movement demands of 9 elite officials across 12 Super Rugby matches were calculated, using global positioning system devices. Total distance (m), relative distance (m·min-1 ), percentage time spent within various speed zones were calculated across a match. Heart rate responses were also recorded throughout each match. Cohen d effect sizes were reported to examine the within match variations...

1. Mice that were heterozygous dominant for the enu1 and enu2 mutation in PAH resulted in hepatic PAH assays for SCMC that had significantly increased calculated Km (wt/enu1, 1.84-2.12 fold increase and wt/enu2 a 2.75 fold increase in PAH assays). The heterozygous dominant phenotypes showed a significantly reduced catalytic turnover of SCMC (wt/enu1, 6.11 fold decrease and wt/enu2 an 11.25 fold decrease in calculated Vmax ). Finally, these phenotypes also had a significantly reduced clearance, CLE (wt/enu1, 13...

Peer-review is an essential activity for the vast majority of credited scientific journals and represents the cornerstone for assessing the quality of potential publications, since it is substantially aimed to identify drawbacks or inaccuracies that may flaw the outcome or the presentation of scientific research. Since the importance of this activity is seldom underestimated by some referees, the purpose of this article is to present a personal and arbitrary perspective on how a scientific article should be peer-reviewed, offering a tentative checklist aimed to describe the most important criteria that should be considered...

Statistical analyses are an integral component of scientific research, and for decades, biologists have applied transformations to data to meet the normal error assumptions for F and t tests. Over the years, there has been a movement from data transformation toward model reformation-the use of non-normal error structures within the framework of the generalized linear model (GLM). The principal advantage of model reformation is that parameters are estimated on the original, rather than the transformed scale...

Neural spike rate data are more restricted in range than related psychophysical data. For example, several studies suggest a compressive (roughly cube root) nonlinear relationship between wavelength-opponent spike rates in primate midbrain and color appearance in humans, two rather widely separated domains. This presents an opportunity to partially bridge a chasm between these two domains and to probe the putative nonlinearity with other psychophysical data. Here neural wavelength-opponent data are used to create cortical competition models for hue opponency...

Although handball is a contact sport with a high risk of acute match injuries, their mechanisms have not yet been investigated. We aimed to describe the mechanisms of acute match injuries in elite male handball and evaluate referee performance in injury situations. Based on injury surveillance from the 24th Men's Handball World Championship 2015 in Qatar, injury situations and the referee decisions were identified on video footage. A total of 55 injury situations and 37 referee decisions were included for analysis...

The evaluation of match officials' neuromuscular performance is now an important consideration and the vertical jump test is considered suitable for assessing lower limb power, partly because it is directly related to refereeing. The aim of this study, therefore, was to determine the effect of soccer matches on match officials' vertical jump performance by assessing various biomechanical variables. Eighteen field referees (FRs) and 36 assistant referees (ARs) who officiated in 18 official matches participated in this study...

BACKGROUND: Cardiovascular disease (CVD) is the primary cause of morbidity and mortality in Ireland and worldwide. Male sporting referees registered with the Gaelic Athletic Association (G.A.A.) represent the Irish male population due to the wide range of ages and CVD risk factors. Although G.A.A. referees, a predominately male population, play a pivotal part in the success of the game, there is a paucity of epidemiological evidence relating to their CVD health status. AIMS: The purpose of this study was to assess the CVD risk factor profile of male G...

INTRODUCTION AND HYPOTHESIS: The terminology in current use for sexual function and dysfunction in women with pelvic floor disorders lacks uniformity, which leads to uncertainty, confusion, and unintended ambiguity. The terminology for the sexual health of women with pelvic floor dysfunction needs to be collated in a clinically-based consensus report. METHODS: This report combines the input of members of the Standardization and Terminology Committees of two International Organizations, the International Urogynecological Association (IUGA), and the International Continence Society (ICS), assisted at intervals by many external referees...
