South Asian Youth as Vaccine Agents of Change (SAY-VAC): evaluation of a public health programme to mobilise and empower South Asian youth to foster COVID-19 vaccine-related evidence-based dialogue in the Greater Toronto and Hamilton Area, Canada.

OBJECTIVES: There have been substantial amounts of misinformation surrounding the importance, safety and effectiveness of the COVID-19 vaccine. The impacts of this misinformation may be augmented as they circulate among ethnic communities, who may concurrently face other barriers related to vaccine uptake and access. To combat some of the key sources of COVID-19 vaccine misinformation among the South Asian communities of the Greater Toronto and Hamilton Area (GTHA), an interdisciplinary team of researchers and marketing experts established the South Asian Youth as Vaccine Agents of Change (SAY-VAC) programme to support and empower South Asian youth to disseminate COVID-19 vaccine information. DESIGN: Cross-sectional and one-group pretest-post-test design. SETTING: GTHA. PARTICIPANTS: South Asian youth (18-29 years). INTERVENTION: The team partnered with grass-roots South Asian organisations to collaborate on shared objectives, curate key concerns, create video products regarding the COVID-19 vaccine that would resonate with the community, disseminate the products using established social media channels and evaluate the effectiveness of this effort. OUTCOMES: We assessed the change in self-reported knowledge about the COVID-19 vaccine and participant confidence to facilitate a conversation around the COVID-19 vaccine using pre-post surveys, after the implementation of the SAY-VAC programme. RESULTS: In total, 30 South Asian youth (median age=23.2 years) from the GTHA participated in the programme. After completing the SAY-VAC programme, participants reported an increase in their self-reported knowledge regarding the COVID-19 vaccine from 73.3% to 100.0% (p=0.005), and their self-reported confidence to have a conversation about the vaccine with their unvaccinated community members increased from 63.6% to 100.0% (p=0.002). Overall, 51.9% of the participants reported being able to positively affect an unvaccinated/community member's decision to get vaccinated. CONCLUSIONS: The SAY-VAC programme highlights the importance of community partnerships in developing and disseminating culturally responsive health communication strategies. A constant assessment of the evidence and utilisation of non-traditional avenues to engage the public are essential.

Etiology of Failed Anterior Cruciate Ligament Reconstruction: a Scoping Review.

PURPOSE OF REVIEW: Recent literature was reviewed to identify and summarize the etiology of primary anterior cruciate ligament (ACL) reconstruction (ACLR) failure reported. METHODS: The databases Embase, PubMed, and Medline were searched on March 10, 2022, for English-language, clinical studies that reported on the etiology of failure of primary ACLR. The studies were systematically screened in duplicate and data abstracted. RECENT FINDINGS: Forty-three studies were identified that reported mode of failure in primary ACLR. Trauma (43 studies), technical error (11 studies), and biology (9 studies) remain the most reported etiologies of ACLR failure. A combination of causes was listed in three studies. No reported cause or "other" was listed in 22 studies. Many clinical studies fail to report etiology of ACLR failure. Level of detail provided regarding mode of failure varies widely. Trauma, technical error, and biological failure remain the leading etiologies of ACLR failure reported in recent literature. Technical error is likely underreported and a contributing factor in traumatic failures.

Quadriceps tendon autograft for pediatric anterior cruciate ligament reconstruction results in promising postoperative function and rates of return to sports: A systematic review.

PURPOSE: To assess the performance of the quadriceps tendon (QT) autograft in pediatric anterior cruciate ligament reconstruction (ACLR). METHODS: A systematic search of MEDLINE, PubMed, and EMBASE was conducted on March 1, 2021. Studies of all levels of evidence reporting outcomes and/or complications after QT autograft ACLR in pediatric patients (≤ 18 years old) were eligible for inclusion. Study demographics, patient demographics, reported outcomes, and complications were abstracted. Screening and data abstraction were designed in accordance with PRISMA and R-AMSTAR guidelines. Descriptive statistics were presented when applicable, with data for heterogeneous outcomes presented in narrative summary fashion. RESULTS: A total of 14 studies examining 596 patients (46.3% female), mean age 15.4 years, were included in this systematic review. Mean postoperative Lysholm scores ranged from 94.0 to 99.5. Mean postoperative IKDC subjective scores ranged from 75.9 to 94.0. Limb symmetry index ranged from 96.8 ± 10.4 to 100.4 ± 7.6% across multiple hop tests. Return to sports (RTS) rates ranged from 88.9 to 91.7%. Eleven studies reported postoperative complications, whereby 16 patients (4.8%) experienced contralateral complications and injuries. Forty-six patients (9.4%) experienced ipsilateral complications, including ten graft failures (2.5%) and two growth disturbances (0.6%). CONCLUSIONS: QT autograft ACLR in the pediatric population retains the potential of regaining a preinjury level of knee stability, and yields promising postoperative function and rates of RTS, yielding comparable outcomes relative to HT autograft and the reference-standard BPTB ACLR that have previously been described in the literature. Moreover, use of the QT autograft is associated with low rates of postoperative complications, including graft failure and growth disturbances in this active and high-risk patient population in observational studies to date. Therefore, clinical equipoise exists to further appraise the influence of QT autograft on postoperative outcomes compared to aforementioned autograft options in a randomized control trial fashion. LEVEL OF EVIDENCE: IV.
