NIRS Measurements with Elite Speed Skaters: Comparison Between the Ice Rink and the Laboratory

Wearable, wireless near-infrared (NIR) spectrometers were used to compare changes in on-ice short-track skating race simulations over 1,500 m with a 3-min cycle ergometry test at constant power output (400 W). The subjects were six male elite short-track speed skaters. Both protocols elicited a rapid desaturation (∆TSI%) in the muscle during early stages (initial 20 s); however, asymmetry between right and left legs was seen in ΔTSI% for the skating protocol, but not for cycling. Individual differences between skaters were present in both protocols. Notably, one individual who showed a relatively small TSI% change (-10.7%, group mean = -26.1%) showed a similarly small change during the cycling protocol (-5.8%, group mean = -14.3%). We conclude that NIRS-detected leg asymmetry is due to the specific demands of short-track speed skating. However, heterogeneity between individuals is not specific to the mode of exercise. Whether this is a result of genuine differences in physiology or a reflection of differences in the optical properties of the leg remains to be determined

Efficacy of Coronavirus Disease (COVID-19) Safety Protocol at the 2021 Wrestling European Olympic Games Qualifier Organized in Budapest = A koronavírus-járvány (COVID-19) biztonsági protokolljának hatékonysága a 2021-es olimpiai játékok európai kvalifikációs birkózóversenyén, Budapesten

Bevezetés és cél: A COVID-19 világjárvány számos nehézséget okoz a többnapos nemzetközi sportesemények szervezésében. Ennek oka - részben - a sportolók közötti szoros fizikai kapcsolat, amely köztudottan elősegíti a vírus terjedését, még az egyéni sportágakban, például a birkózásban is. Ezért a birkózóselejtezőn rendkívül fontos volt a betegség szűrésének bevezetése, és a fertőzött résztvevők kizárása (majd elkülönítése). Az orvosi csapat és a COVID-marsallok együtt dolgoztak egy szűrési protokoll kidolgozásán, és céljuk volt, hogy a verseny során teszteljék annak hatékonyságát. Anyag és módszerek: A versenyen 37 ország 281 versenyzője vett részt. A Magyarországra való belépés kritériuma a polimeráz láncreakció (PCR) negatív tesztje, járványügyi és tüneti negativitás volt 72 órán belül. Antigén gyorsteszteket (ART) és szükség esetén újratesztelést is végeztünk. Kiutazáskor negatív PCR-teszt, vagy a karanténidőszak lejárta után kiállított igazolás volt szükséges. Eredmények: Összesen 1287 PCR-tesztet és 1250 gyorstesztet végeztünk. Érkezéskor 21 PCR-pozitív (1,4%) személy volt, akiket karanténba helyeztek. Az induláskor 6 PCR-teszt volt pozitív (0,47%). Az akkreditációkor elvégzett ART tesztek közül egy volt pozitív. Következtetés: Az egészségügyi személyzet sikeres protokollt dolgozott ki a COVID-19 szűrésére és a résztvevők izolálására, amit az induláskor tapasztalt nagyon alacsony pozitivitás is jelez. Így ez a protokoll alkalmazható többnapos nemzetközi sportesemények szervezésénél. Introduction and Aim: The pandemic Covid-19 imposes several difficulties to organize multi-day international sports events. This is - in part - due to the close physical contact among the athletes, known to promote the spread of virus, even in individual sports, such as wrestling. Thus, at the Wrestling Qualifier it was of utmost importance to introduce screening for the disease and exclude infected participants (and then isolate them). The medical team and the COVID Marshals worked together on developing a screening protocol and aimed to test the efficacy during this competition. Material and Methods: The event was attended by 281 competitors from 37 countries. The criteria to enter Hungary were a negative polymerase chain reaction (PCR) test, epidemiological and symptomatic negativity within 72 hours. We also performed Antigen rapid tests (ART, chromatographic immunoassay) and retesting if necessary. Upon departure a negative PCR test or a certificate issued after the end of the quarantine period was required. Results: In total, 1,287 PCR tests and 1,250 rapid tests were performed. At arrival, there were 21 PCR positive (1.4%) individuals, and they were quarantined. At the departure 6 PCR tests were positive (0.47%). One of the ARTs performed at the accreditation was positive. Conclusion: The medical staff has developed a successful protocol to screen for Covid-19 and isolate participants as indicated by the very low positivity for Covid-19 at departure. Thus such protocol can be used for organizing multi-day international sports events

Avoiding, diagnosing and treating well leg compartment syndrome after pelvic surgery

Background Patients undergoing prolonged pelvic surgery may develop compartment syndrome of one or both lower limbs in the absence of direct trauma or pre‐existing vascular disease (well leg compartment syndrome). This condition may have devastating consequences for postoperative recovery, including loss of life or limb, and irreversible disability. Methods These guidelines represent the collaboration of a multidisciplinary group of colorectal, vascular and orthopaedic surgeons, acting on behalf of their specialty associations in the UK and Ireland. A systematic analysis of the available peer‐reviewed literature was undertaken to provide an evidence base from which these guidelines were developed. Results These guidelines encompass the risk factors (both patient‐ and procedure‐related), diagnosis and management of the condition. Key recommendations for the adoption of perioperative strategies to facilitate prevention and effective treatment of well leg compartment syndrome are presented. Conclusion All surgeons who carry out abdominopelvic surgical procedures should be aware of well leg compartment syndrome, and instigate policies within their own institution to reduce the risk of this potentially life‐changing complication
