ItemBiathlon Injury and Illness Surveillance project (BIIS): development of biathlon-specific surveillance forms in English, Russian, French and German.(BMJ Publishing Group, 2019)Objective: The aim of this project was to adapt the English, French, German and Russian versions of the International Olympic Committee (IOC) injury and illness surveillance form to be sport-specific for use in biathlon. Methods: 23 medical representatives from 16 of the 55 biathlon federations participated in this project to adapt the form and create disease coding relevant to biathlon. The English version of the IOC injury and illness surveillance form was used as the primary template. Four review rounds were used to develop electronic fillable PDF forms. The changes were then forward translated onto the Russian, French and German forms. Results: Changes were made to event type to biathlon-specific events. A weekly reporting format was adopted in line with the race week format of World Cup events. Wherever possible, coding replaced free-text format to avoid translation issues. New codes were created to describe the time of injury/illness. A new symptom code was added to reflect the prevalence of respiratory infection: sore throat/cold symptoms. As the number of athletes in a team differs between weeks in the season, an additional question was added to ask for the 'number of athletes in the team for the week' and for the season. Conclusion: This project provides a biathlon-specific injury and illness surveillance form in English, French, German and Russian. This forms the basis for surveillance that will contribute to a greater understanding of the illness and injury rate in elite biathletes and ultimately to enhanced athlete well-being and success in biathlon, and winter sports more generally.

ItemOsteoarthritis- a systematic review of long-term safety implications for osteoarthritis of the knee(BMC, 2019-04-09)There is no cure for knee osteoarthritis (KOA) and typically patients live approximately 30-years with the disease. Most common medical treatments result in short-term palliation of symptoms with little consideration of long-term risk. This systematic review aims to appraise the current evidence for the long-term (≥12 months) safety of common treatments for knee osteoarthritis (KOA).

ItemSystematic clinical evidence review of NASHA (Durolane hyaluronic acid) for the treatment of knee osteoarthritis(DOVE MEDICAL PRESS LTD, 2018)BACKGROUND: Pain and limitations in joint mobility associated with knee osteoarthritis (OA) are clinically challenging to manage, and advanced progression of disease can often lead to total knee arthroplasty. Intra-articular injection of hyaluronic acid (HA), also referred to as viscosupplementation, is a non-surgical treatment approach for OA, the effectiveness of which may depend on the HA composition, and the length of time over which it resides in the joint. One of the available options for such therapies includes NASHA (Durolane HA), a non-animal, biofermentation-derived product, which is manufactured using a process that stabilizes the HA molecules to slow down their rate of degradation and produce a unique formulation with a terminal half-life of ~1 month. The objectives of the current review were to assess, in patients with OA of the knee, the efficacy and safety of intra-articular treatment with NASHA relative to control (saline) injections, other HA products, and other injectables (corticosteroids, platelet-rich plasma, mesenchymal stem cells). METHODS: This systematic evidence review examines patient outcomes following NASHA treatment as described in published data from studies conducted in subjects with knee OA. A Preferred Reporting Items for Systematic Reviews and Meta-analyses-compliant literature search strategy yielded 11 eligible clinical studies with a variety of comparator arms. Outcomes assessed at various time points following intra-articular treatment included measures of pain, function, quality of life, and incidence of treatment-related adverse events (AEs). RESULTS: The available evidence reported for the clinical studies assessed demonstrates sustained and effective relief of knee OA symptoms following a single injection of NASHA. In addition, an excellent biocompatibility profile is observed for NASHA as an intra-articular therapy for OA, as reflected by the low rate of AEs associated with treatment. CONCLUSION: Treatment with NASHA is an effective and safe single-injection procedure, which can be beneficial in the clinical management of knee OA.

Iteme Analysis of Platelet-Rich Plasma Extraction Variations in Platelet and Blood Components Between 4 Common Commercial Kits(SAGE PUBLICATIONS INC, 2017-01)BACKGROUND: Platelet-rich plasma (PRP) has been extensively used as a treatment in tissue healing in tendinopathy, muscle injury, and osteoarthritis. However, there is variation in methods of extraction, and this produces different types of PRP. PURPOSE: To determine the composition of PRP obtained from 4 commercial separation kits, which would allow assessment of current classification systems used in cross-study comparisons. STUDY DESIGN: Controlled laboratory study. METHODS: Three normal adults each donated 181 mL of whole blood, some of which served as a control and the remainder of which was processed through 4 PRP separation kits: GPS III (Biomet Biologics), Smart-Prep2 (Harvest Terumo), Magellan (Arteriocyte Medical Systems), and ACP (Device Technologies). The resultant PRP was tested for platelet count, red blood cell count, and white blood cell count, including differential in a commercial pathology laboratory. Glucose and pH measurements were obtained from a blood gas autoanalyzer machine. RESULTS: Three kits taking samples from the "buffy coat layer" were found to have greater concentrations of platelets (3-6 times baseline), while 1 kit taking samples from plasma was found to have platelet concentrations of only 1.5 times baseline. The same 3 kits produced an increased concentration of white blood cells (3-6 times baseline); these consisted of neutrophils, leukocytes, and monocytes. This represents high concentrations of platelets and white blood cells. A small drop in pH was thought to relate to the citrate used in the sample preparation. Interestingly, an unexpected increase in glucose concentrations, with 3 to 6 times greater than baseline levels, was found in all samples. CONCLUSION: This study reveals the variation of blood components, including platelets, red blood cells, leukocytes, pH, and glucose in PRP extractions. The high concentrations of cells are important, as the white blood cell count in PRP samples has frequently been ignored, being considered insignificant. The lack of standardization of PRP preparation for clinical use has contributed at least in part to the varying clinical efficacy in PRP use. CLINICAL RELEVANCE: The variation of platelet and other blood component concentrations between commercial PRP kits may affect clinical treatment outcomes. There is a need for standardization of PRP for clinical use.
