SummaryMRI technology has profoundly transformed current healthcare and research systems globally. The rapidly growing burden of non-communicable diseases in Africa has underscored the importance of improving access to MRI equipment as well as training and research opportunities on the continent. The Consortium for Advancement of MRI Education & Research in Africa (CAMERA) is a network of African experts, global partners, and ISMRM/ESMRMB members implementing novel strategies to advance MRI access and research in Africa. To identify challenges to MRI usage and provide a framework for addressing MRI needs in the region, CAMERA conducted a Needs Assessment Survey (NAS) and a series of symposia at international MRI society meetings over a 2-year period. The 68-question NAS was distributed to MRI users in Africa and completed by 157 clinicians and scientists from across Sub-Saharan Africa (SSA). On average, the number of MRI scanners per million people remained at Graphical AbstractAfrica has a massive population with few infrastructural resources and an untapped potential to effect transformative change in healthcare. To advance MRI access across all African countries and meet the sustainable development goals of improving health and wellbeing in low-resource settings over the next decade, the MRI community is called to partner with CAMERA to create enabling clinical and research MRI environments that will utilize the rich intellectual resources in Africa to realize lasting and equitable MRI for all Africans and the world at large.

Radiofrequency ablation (RFA) has gained significant recent global interest in the treatment of benign thyroid nodules and thyroid cancer. It is a relatively new, minimally invasive, thermal ablation technique that is an alternative to surgery. Several clinical practice guidelines (CPGs), consensus statements, and recommendations currently exist for the use of RFA in the treatment of benign thyroid nodules and thyroid cancers. These documents have considerable variability amongst them, and to date, their quality and methodologic rigor have not been appraised.To identify and perform a quality appraisal of clinical practice guidelines for RFA in the treatment of benign thyroid nodules and thyroid cancer using the Appraisal of Guidelines for Research and Evaluation (AGREE II) tool.A comprehensive literature search was performed in MEDLINE (via PubMed), EMBASE, and SCOPUS databases from inception to November 1, 2021. Four reviewers independently evaluated each guideline using the AGREE II instrument. Scaled domain scores were generated and the threshold used for satisfactory quality was60%. Additionally, intraclass correlation coefficients (ICCs) were calculated to determine level of agreement between reviewers.Seven guidelines were selected for final evaluation based on inclusion/exclusion criteria. Two guidelines were classified "high" quality, one "average" quality, and the rest "low" quality. The "Clarity and Presentation" (65.68 ± 26.1) and "Editorial Independence" (61.32 ± 25.8) domains received the highest mean scores, while the "Applicability" (32.14 ± 22.8) and "Rigor of Development" (45.02 ± 29.8) domains received the lowest mean scores. ICC statistical analysis showed high magnitude of agreement between reviewers with a range of (0.722-0.944).Reflecting upon our quality appraisal, it is evident that the quality and methodologic rigor of RFA guidelines can be improved upon in the future. Our findings also elucidate the existing variability/discrepancies amongst guidelines in the indications and use of RFA.

This study assesses the diagnostic reliability of a novel photogrammetric measurement to distinguish sagittal craniosynostosis (SS) from control and false positive cases (SNS).Head CTs from 2014-2020 were reviewed for patients with sagittal synostosis (SS, n = 177), presumed sagittal synostosis with normal imaging (SNS, n = 30), and controls (n = 100). Using preoperative clinical photographs and CTs, a measurement reflecting the anterior-posterior location of the vertex was measured using an angle drawn between the cranial vertex, nasion, and opisthocranion (VNO) in profile view, with the head in a neutral position.Mean age at pre-operative head CT was 9.5 months for the SS cohort, 4.2 months for the SNS cohort, and 8.9 months for controls (p = .327). Mean age at pre-operative clinical photograph was 9.5 months for the SS cohort and 4.2 months for the SNS cohort (p = .149). Pearson correlations revealed no significant association between age and VNO angle. The average VNO angle measured on clinical photographs was 54.7° ± 3.8° for the SS group, 43.1° ± 2.2° for the SNS group, and 41.1° ± 3.7° for controls (p .001). Receiver operating characteristic (ROC) analysis yielded a cut-off of ≥ 50° to identify SS. Diagnostic sensitivity and specificity were 96.6% and 99.2%, respectively. Three-rater analysis yielded an average ICC of 0.742 (p = .004).Measurement of the VNO angle is a reliable screening tool to diagnose sagittal craniosynostosis, with an angle of 50° or more suggesting suture synostosis. This method relies on the relationship between the anterior displacement of the vertex and occipital bulleting to approach the diagnostic accuracy of CT imaging.

The authors' group characterized the cranio-maxillo-facial workforce 10 years ago, revealing high levels of career satisfaction but significant gender disparity. This study provides an updated profile of the international cranio-maxillo-facial workforce.A 30-question electronic survey was distributed to 387 cranio-maxillo-facial surgeons with membership in the American Society of Craniofacial Surgeons, American Society of Maxillofacial Surgeons, and international Society of Craniofacial Surgery. Questions related to demographics, training background, practice setting, surgical volume, career satisfaction, and perceived discrimination. Independent samples t test was used to compare continuous variables.The authors received 91 responses (response rate = 23.5%). The majority of respondents were White (n = 73, 80.2%), non-Hispanic (n = 85, 93.4%), heterosexual (n = 72, 79.1%), cisgender males (n = 74, 81.3%). Practice setting was primarily academic, 65.9% (n = 60) and group/hospital-based 88.3% (n = 68), with two-thirds of respondents practicing in the United States. Female surgeons reported earlier planned retirement (66 versus 70 years, P = 0.012) and more personal encounters with discrimination of any kind (69% versus 29%, P = 0.033). US craniofacial surgeons reported more racial and sexual orientation-based discrimination compared with non-US surgeons ( P = 0.049 and P = 0.048, respectively). Older surgeons (55 years old) reported less perceived gender discrimination ( P = 0.041). There was no difference between subgroups in career satisfaction or likelihood of repeating/recommending a cranio-maxillo-facial fellowship.Female representation in cranio-maxillo-facial surgery on an international scale has increased over the past decade, but this study demonstrates persistent, disparate perception of workplace discrimination by gender, practice region, and age.
