ABSTRACT
BACKGROUND AND OBJECTIVES: Over the past few years in Québec, Canada, exclusion criteria for blood donation and plasma donation for fractionation have been modified. Héma-Québec, the institution responsible for blood products, has made changes to allow more inclusive access to blood and plasma donation, in accordance with evolving scientific data concerning donation safety. The study, conducted before those changes were implemented, aimed to assess acceptability of recipients and parents of recipients of plasma-derived products for men who have sex with men (MSM) to become eligible to donate plasma for fractionation. MATERIALS AND METHODS: Eight qualitative interviews (4 focus groups, 4 individual) were conducted with a total of 17 plasma product recipients and parents of children needing plasma-derived products. Data were analysed using thematic analysis. RESULTS: Participants were rather favourable regarding acceptability of MSM as potential donors. Participants viewed this change as necessary and beneficial. They also felt they must rely on trust in Héma-Québec, conferred automatically or by default. However, some participants raised concerns about donation safety and reported feeling helpless regarding inclusion of MSM. The importance of being informed and that recipients' safety be prioritized first and foremost were also mentioned. CONCLUSION: Despite their nuanced attitudes, recipients showed high levels of acceptability of including MSM in plasma donation for fractionation. Actions can be taken to reduce concerns regarding the safety of products received.
ABSTRACT
AIM: To develop and validate an algorithm to rapidly distinguish transient synovitis (TS) of the hip from differential diagnoses without additional tests. METHODS: This retrospective cohort study included all children admitted for non-traumatic limping in the emergency department at Lille University-Hospital between 2016 and 2020. The gold standard was a definitive diagnosis at follow-up visit. All variables associated with acute limping in children were analysed in univariate and multivariable analyses. An algorithm was then developed using recursive partitioning and validated internally on a subset of patients. RESULTS: There were 995 patients included (mean age 5.3 years; males 63%); 337 had a TS including 210 confirmed at follow-up visit and 354 another diagnosis. After multivariable analysis, the relevant variables for distinguishing between TS and differential diagnoses were: age 3-10 years, absence of fever, absence of local inflammation, sudden onset of limping on awakening. An algorithm combining these variables was developed (n = 297) and validated internally (n = 175) for children >12 months with limping for ≤10 days, with a specificity of 98.2% and a positive likelihood ratio of 19.6. No serious differential diagnoses were missed. CONCLUSION: Use of this algorithm enables the diagnosis of TS without additional tests and without missing serious differential diagnoses.
