- We report on an exploratory study where the first 60 seconds of the video recording of a user interaction are used to predict the user’s experienced task difficulty. This approach builds on previous work on “thin slices” of human-human behavior, and applies it to human- computer interaction. In the scenario of interacting with a photocopy machine, automated video coding showed that the Activity and Emphasis predicted 46.6% of the variance of task difficulty. This result closely follows reported results on predicting negotiation outcomes from conversational dynamics using similar variables on the speech signal.

- Saltatorial locomotion is a type of hopping gait that in mammals can be found in rabbits, hares, kangaroos, and some species of rodents. The molecular mechanisms that control and fine-tune the formation of this type of gait are unknown. Here, we take advantage of one strain of domesticated rabbits, the sauteur d’Alfort, that exhibits an abnormal locomotion behavior defined by the loss of the typical jumping that characterizes wild-type rabbits. Strikingly, individuals from this strain frequently adopt a bipedal gait using their front legs. Using a combination of experimental crosses and whole genome sequencing, we show that a single locus containing the RAR related orphan receptor B gene (RORB) explains the atypical gait of these rabbits. We found that a splice-site mutation in an evolutionary conserved site of RORB results in several aberrant transcript isoforms incorporating intronic sequence. This mutation leads to a drastic reduction of RORB-positive neurons in the spinal cord, as well as defects in differentiation of populations of spinal cord interneurons. Our results show that RORB function is required for the performance of saltatorial locomotion in rabbits.Author summaryRabbits and hares have a characteristic jumping gait composed of an alternate rhythmical movement of the forelimbs and a synchronous bilateral movement of the hindlimbs. We have now characterized a recessive mutation present in a specific strain of domestic rabbits (sauteur d’Alfort) that disrupts the jumping gait. The mutation causing this defect in locomotion pattern occurs in the gene coding for the transcription factor RORB that is normally expressed in many regions of the nervous system especially in the spinal cord dorsal horn. Our results show that expression of RORB is drastically reduced in the spinal cord of affected rabbits which results in a developmental defect. This study is an advance in our understanding how locomotion is controlled in vertebrates.

- Objectives: To explore the performance of retrospective health data collected from athletes before Athletics championships for the analysis of risk factors for in-competition injury and illness (IandI). Methods: For the 2013 European Athletics Indoor Championships, a self-report questionnaire (PHQ) was developed to record the health status of 127 athletes during the 4 weeks prior to the championship. Physician-based surveillance of in-competition IandI among all 577 athletes registered to compete was pursued during the championships. Results: 74 athletes (58.3%) from the sample submitted a complete PHQ, 21 (28%) of these athletes sustained at least one injury and/or illness during the championships. Training more than 12 h/week predisposed for sustaining an in-competition injury, and a recent health problem for in-competition illness. Among the 577 registered athletes, 60 injuries (104/1000 registered athletes) were reported. 31% of injuries were caused by the track, and 29% by overuse. 29 illnesses were reported (50/1000 registered athletes); upper respiratory tract infection and gastro-enteritis/diarrhoea were the most reported diagnoses. Conclusions: Pre-participation screening using athletes self-report PHQ showed promising results with regard to identification of individuals at risk. Indoor injury types could be attributed to extrinsic factors, such as small track size, track inclination, and race tactics. (C) 2014 Elsevier Ltd. All rights reserved.

- Objectives: To analyse the association between pre-participation health status and in-championships injuries in a large dataset from seven international athletics championships, and to determine the health status of athletes during the four weeks before the start of international athletics championships. Design: Prospective cohort study.Methods: We used data collected from athletes of national teams with medical staff who participated i) in a pre -participation health survey (retrospective data collection) and ii) in an in-championships injury surveillance (prospective data collection) during seven international athletics championships (2013-2018). We performed a binomial logistic regression with in-championship injury (yes/no) as the dependent variable and sex, age, discipline (explosive/endurance), type of championships (outdoor/indoor) and pre-participation injury com-plaint (yes/no) and pre-participation illness complaint (yes/no) as independent variables, with odds ratios (OR) and 95% confidence intervals (95% CI).Results: Out of the 1095 athletes included 31.2% reported an injury complaint during the 4 weeks before the championships and 21.6% an illness complaint. The univariate model showed that discipline, type of champion-ships and pre-participation injury complaints (OR = 2.57, 95%CI: 1.66 to 3.97) were significantly associated with in-championships injuries, and the multivariable model showed that type of championships and pre -participation injury complaints (OR = 2.64, 95%CI: 1.60 to 4.36) remained significantly associated with in -championships injuries.Conclusions: Our present study shows that an injury complaint during the four weeks before an international ath-letics championship significantly increased risk of sustaining an injury during the following championship, which was reported by about one third of athletes with differences between sex and disciplines.

- Background Illnesses impair athletes’ participation and performance. The epidemiology of illness in athletics is limited.Objective To describe the occurrence and characteristics of illnesses during international athletics championships (indoor and outdoor), and to analyse differences with regards to athletes’ sex and participation in explosive and endurance disciplines.Methods During 11 international championships held between 2009 and 2017, physicians from both national medical teams and the local organising committees reported daily on all athlete illnesses using a standardised report form. Illness frequencies, incidence proportions (IPs) and rates (IRs), and relative risks (RR) with 95% CIs were calculated.Results During the 59 days of the 11 athletics championships, 546 illnesses were recorded in the 12 594 registered athletes equivalent to IP of 43.4 illnesses per 1000 registered athletes (95% CI 39.8 to 46.9) or IR of 1.2 per 1000 registered athlete days (95% CI 1.1 to 1.2). The most frequently reported illnesses were upper respiratory tract infections (18.7%), exercise-induced fatigue/hypotension/collapse (15.4%) and gastroenteritis (13.2%). No myocardial infarction was recorded. A total of 28.8% of illnesses were expected to lead to time loss from sport. The illness IP was similar in male and female athletes, with few differences in illness characteristics. During outdoor championships, the illness IP was higher in endurance than explosive disciplines (RR=1.87; 95% CI 1.58 to 2.23), with a considerably higher IP of exercise-induced illness in endurance disciplines, but a similar upper respiratory tract infection IP in both discipline groups.Conclusions Illness prevention strategies during international athletics championships should be focused on the most frequent diagnoses in each discipline group.

- Objective To analyse differences between athletic disciplines in the frequency and characteristics of injuries during international athletics championships. Methods Study design, injury definition and data collection procedures were similar during the 14 international championships (2007-2018). National medical teams and local organising committee physicians reported all newly incurred injuries daily on a standardised injury report form. Results were presented as number of injuries and number of injuries per 1000 registered athletes, separately for male and female athletes, and for each discipline. Results From a total of 8925 male and 7614 female registered athletes, 928 injuries were reported in male and 597 in female athletes. The discipline accounting for the highest proportion of injuries was sprints, for both men (24%) and women (26%). The number of injuries per 1000 registered athletes varied between disciplines for men and women: highest in combined events for male athletes (235 (95% CI 189 to 281)) and female athletes (212 (95% CI 166 to 257)), and lowest for male throwers (47 (95% CI 35 to 59)) and female throwers (32 (95% CI 21 to 43)) and for female race walkers (42 (95% CI 19 to 66)). Injury characteristics varied significantly between disciplines for location, type, cause and severity in male and female athletes. Thigh muscle injuries were the main diagnoses in the disciplines sprints, hurdles, jumps, combined events and race walking, lower leg muscle injuries in marathon running, lower leg skin injury in middle and long distance running, and trunk muscle and lower leg muscle injuries in throws. Conclusions Injury characteristics differed substantially between disciplines during international athletics championships. Strategies for medical service provision (eg, staff, facilities) during athletics championships should be discipline specific and be prepared for targeting the main injuries in each discipline.

- Objectives: The quality of epidemiological injury data depends on the reliability of reporting to an injury surveillance system. Ascertaining whether all physicians/physiotherapists report the same information for the same injury case is of major interest to determine data validity. The aim of this study was therefore to analyse the data collection reliability through the analysis of the interrater reliability. Design: Cross-sectional survey. Methods: During the 2016 European Athletics Advanced Athletics Medicine Course in Amsterdam, all national medical teams were asked to complete seven virtual case reports on a standardised injury report form using the same definitions and classifications of injuries as the international athletics championships injury surveillance protocol. The completeness of data and the Fleiss kappa coefficients for the inter-rater reliability were calculated for: sex, age, event, circumstance, location, type, assumed cause and estimated time-loss. Results: Forty-one team physicians and physiotherapists of national medical teams participated in the study (response rate 89.1%). Data completeness was 96.9%. The Fleiss kappa coefficients were: almost perfect for sex (k = 1), injury location (k = 0.991), event (k = 0.953), circumstance (k = 0,942), and age = 0.870), moderate for type (k = 0.507), fair for assumed cause (k = 0.394), and poor for estimated time loss (k = 0.155). Conclusions: The injury surveillance system used during international athletics championships provided reliable data for "sex", "location", "event", "circumstance", and "age". More caution should be taken for "assumed cause" and "type", and even more for "estimated time-loss". This injury surveillance system displays satisfactory data quality (reliable data and high data completeness), and thus, can be recommended as tool to collect epidemiology information on injuries during international athletics championships.

- As the third wave of the COVID-19 pandemic hit Portugal, it forced the country to reintroduce lockdown measures due to hospitals reaching their full capacities. Under these circumstances, environmental contamination by SARS-CoV-2 in different areas of one of Portugal’s major Hospitals was assessed between 21 January and 11 February 2021. Air samples (n = 44) were collected from eleven different areas of the Hospital (four COVID-19 and seven non-COVID-19 areas) using Coriolis® μ and Coriolis® Compact cyclone air sampling devices. Surface sampling was also performed (n = 17) on four areas (one COVID-19 and three non-COVID-19 areas). RNA extraction followed by a one-step RT-qPCR adapted for quantitative purposes were performed. Of the 44 air samples, two were positive for SARS-CoV-2 RNA (6575 copies/m3 and 6662.5 copies/m3, respectively). Of the 17 surface samples, three were positive for SARS-CoV-2 RNA (200.6 copies/cm2, 179.2 copies/cm2, and 201.7 copies/cm2, respectively). SARS-CoV-2 environmental contamination was found both in air and on surfaces in both COVID-19 and non-COVID-19 areas. Moreover, our results suggest that longer collection sessions are needed to detect point contaminations. This reinforces the need to remain cautious at all times, not only when in close contact with infected individuals. Hand hygiene and other standard transmission-prevention guidelines should be continuously followed to avoid nosocomial COVID-19.
