The association between sport-related concussion and musculoskeletal injury in university rugby athletes

ObjectivesThe study aimed to analyse the association between Sports-Related Concussion (SRC) and Subsequent Musculoskeletal Injury (MSK) in United Kingdom university-aged rugby union players whilst considering the effects of sex, athlete playing position and injury location.DesignRetrospective cohort study. A period of 365 days with 0–90, 91–180 and 181–365 days sub-periods was analysed for the following variables; MSK injury incidence, occurrence, severity, injury location, playing position and sex.SettingInjury data was collected from the Sports Development Centre database at Loughborough University.ParticipantsA total of 408 injuries in 181 athletes (55 females and 126 males) were included.ResultsThe MSK injury incidence of SRC group was significantly higher than control and higher post-SRC than pre-SRC period over a 365-day period (p=0.012 and p=0.034, respectively). The odds ratios of MSK injury incidence between groups and between periods were 1.62 (95% CI, 1.10–2.25) and 1.57 (95% CI ,1.08–2.29). A SRC was not associated with a greater time loss from a subsequent MSK injury or a specific MSK injury location.ConclusionsAthletes with a second recorded injury were more likely to sustain a MSK injury if they had experienced SRC, however, there was no indication a SRC resulted in greater time loss from a MSK injury.     

Building immunization decision-making capacity within the World Health Organization European Region

A National Immunization Technical Advisory Group (NITAG) is a multi-disciplinary body of national experts that provides evidence-based recommendations to policy-makers, assisting them in making sound immunization policy and programme decisions. The World Health Organization (WHO) Regional Office for Europe is working to strengthen the capacity of newly-established NITAGs and has targeted efforts on low- and middle-income countries. The Regional Office, in collaboration with WHO Headquarters and USA Centers for Disease Control and Prevention (CDC), developed a new training strategy and held training workshops to improve NITAGs’ functioning and ability to make evidence-based recommendations. Feedback from countries that participated in trainings indicated that the updated training materials and interactive approach with follow-up technical support enabled them to align their NITAG charters and processes with WHO recommendations. To ensure continued progress, global and regional partners such as WHO and CDC should continue providing technical support to recently established NITAGs.     

Burn mass casualty incidents in Europe: A European response plan within the European Union Civil Protection Mechanism

BackgroundBurn care is centralized in highly specialized burn centers in Europe. These centers are of limited capacity and may be overwhelmed by a sudden surge in case of a burn mass casualty incident. Prior incidents in Europe and abroad have sustained high standards of care through well-orchestrated responses to share the burden of care in several burn centers. A burn mass casualty incident in Romania in 2015 sparked an initiative to strengthen the existing EU mechanisms. This paper aims to provide insight into developing a response plan for burn mass casualties within the EU Civil Protection Mechanism.MethodsThe European Burns Association drafted medical guidelines for burn mass casualty incidents based on a literature review and an in-depth analysis of the Romanian incident. An online questionnaire surveyed European burn centers and EU States for burn mass casualty preparedness.ResultsThe Romanian burn mass casualty in 2015 highlighted the lack of a burn-specific mechanism, leading to the late onset of international transfers. In Europe, 71% of respondents had existing mass casualty response plans, though only 35% reported having a burn-specific plan. A burns response plan for burn mass casualties was developed and adopted as a Commission staff working document in preparation for further implementation. The plan builds on the existing Union Civil Protection Mechanism framework and the standards of the WHO Emergency Medical Teams initiative to provide 1) burn assessment teams for specialized in-hospital triage of patients, 2) specialized burn care across European burn centers, and 3) medevac capacities from participating states.ConclusionThe European burn mass casualty response plan could enable the delivery of high-level burn care in the face of an overwhelming incident in an affected European country. Further steps for integration and implementation of the plan within the Union Civil Protection Mechanism framework are needed.     

Impact of ultra-low dose CT acquisition on semi-automated RECIST tool in the evaluation of malignant focal liver lesions

PurposeTo compare the evaluation of malignant focal liver lesions (FLLs) using a semi-automated RECIST tool with a standard and an ultra-low dose (ULD) computed tomography (CT) protocol.Materials and methodsThirty-four patients with malignant FLLs underwent two abdominal-pelvic CT examinations one using a standard protocol and one using an ULD protocol. There were 23 men and 11 women with a mean age 64.3 ± 14.4 (SD) years (range: 22–91 years). Dosimetric indicators were recorded, and effective dose was calculated for both examinations. Mean malignant FLL attenuation, image noise and contrast-to-noise-ratio (CNR) were compared. The largest malignant FLL per patient was evaluated using the semi-automated RECIST tool to determine longest axis length, longest orthogonal axis length, volume and World Health Organisation area.ResultsDosimetric values were significantly reduced by −56% with ULD compared to standard protocol. No differences in mean malignant FLL attenuation values were found between the two protocols. Image noise was significantly increased for all locations (P < 0.05) with ULD compared to standard protocol, and CNR was significantly reduced (P < 0.05). On the 34 malignant FLLs analyzed, six semi-automated shapes non-concordant with radiologist's visual impression were highlighted with the software, including one FLL (1/34; 3%) with standard CT acquisition only, three FLLs (3/34; 9%) with ULD CT acquisition only and two FLLs (2/34; 6%) with both CT acquisitions. After manual editing, the concordance of the values of the studied criteria between both acquisitions was good and no significant difference was reported.ConclusionSemi-automated RECIST tool demonstrates good performances using ULD CT protocol. It could be used in routine clinical practice with a ULD protocol for follow-up studies in patients with known malignant FLL.     

Improving knowledge and trust in vaccines: A survey-based assessment of the potential of the European Union Clinical Trial Regulation No 536/2014 plain language summary to increase health literacy

The European Clinical Trial Regulation No 536/2014 is the first mandate for a non-technical, publicly disclosed, plain language summary (PLS) of clinical trial results. This easy-to-understand summary has the potential to inform the public about clinical trial results and thereby improve health literacy in vaccines.To investigate the utility of the PLS, we undertook 2 online surveys (July/October 2020) in the United Kingdom, the United States and India. Participants were selected by quota sampling to ensure representation of gender, age and parental status. Those lacking interest in vaccine clinical research were excluded. In survey 1, participants were questioned about their interest in and expectations of vaccine trial results. In survey 2, the perceptions of participants to a range of written communication styles used in publicly available PLSs were evaluated.A total of 66 (13%) and 122 (29%) individuals were excluded solely due to lack of interest in vaccine clinical research in surveys 1 and 2, respectively; 450 respondents (150/country) completed survey 1 and 300 (100/country) completed survey 2. In survey 1, there was a correlation (p < 0.01) between claimed knowledge of and trust in vaccines. Healthcare professionals were the most trusted source for vaccine information, while vaccine companies were ranked relatively low. In survey 2, infographic PLS formats were considered easiest to understand, most engaging and the strongest communicators. Emphasizing the main points of the infographics in the text did not improve comprehension or recall. Most respondents (86%) indicated that they would like to see this type of communication in the future.Overall, this research suggests that the PLS, by optimizing content and format, has a potential to increase health literacy, and thereby, as part of a wider integrated communication strategy, build vaccine knowledge and confidence.
