Improving Equity, Diversity, and Inclusion in Plastic, Reconstructive, and Aesthetic Surgery in Canada: A Call to Action

The global COVID-19 pandemic has brought to light the significant inequities in the delivery of healthcare, vaccine inequity, and differential access to life-saving treatments, which have disproportionately impacted marginalized and racialized populations. In this article, we acknowledge and recognize the centuries-old legacies perpetuating inequity, injustice, and oppression, we discuss the principles of Equity, Diversity, and Inclusion (EDI) and we call our Canadian plastic surgery colleagues and trainees to action. We propose a plan for (1) Education, (2) Mitigating Disparities in the Clinical Setting, and (3) Policy, Societies, and Leadership Education.

Accelerometry as an objective measure of upper-extremity activity

Most studies evaluating the effectiveness of treatments targeting shoulder pathologies use subjective outcome measures such as self-administered questionnaires. To date, there are no validated tools that objectively measure shoulder-specific functional activity. The purpose of this study was to validate wearable accelerometers as an objective proxy for shoulder activity. Ten healthy volunteers wore accelerometers placed at both wrists, the dominant upper arm and the chest while performing standardised shoulder and non-shoulder activities. Recorded tridimensional acceleration was computed into activity counts for epochs of 10 s. Receiver operating characteristics (ROC) curves were built to determine the optimal configuration to classify shoulder-type activities. For single accelerometer placement, the area under the ROC curve (AUC) was optimal for the 10-s epoch (AUC = 0.779) using the wrist placement, with a sensitivity of 94.1% and specificity of 67.5%. The combined upper arm and chest placement had an AUC of 0.985 (94.8% sensitivity, 94.8% specificity). Dual-accelerometer placement (upper arm and chest) is the optimal configuration to classify shoulder activity. However, a sole wrist-based accelerometer can be used as an objective proxy for shoulder activity in long-term unsupervised monitoring with excellent sensitivity and acceptable specificity.

Atlas vertebra realignment and achievement of arterial pressure goal in hypertensive patients: a pilot study

Anatomical abnormalities of the cervical spine at the level of the Atlas vertebra are associated with relative ischaemia of the brainstem circulation and increased blood pressure (BP). Manual correction of this mal-alignment has been associated with reduced arterial pressure. This pilot study tests the hypothesis that correcting mal-alignment of the Atlas vertebra reduces and maintains a lower BP. Using a double blind, placebo-controlled design at a single center, 50 drug naïve (n=26) or washed out (n=24) patients with Stage 1 hypertension were randomized to receive a National Upper Cervical Chiropractic (NUCCA) procedure or a sham procedure. Patients received no antihypertensive meds during the 8-week study duration. The primary end point was changed in systolic and diastolic BP comparing baseline and week 8, with a 90% power to detect an 8/5 mm Hg difference at week 8 over the placebo group. The study cohort had a mean age 52.7+/-9.6 years, consisted of 70% males. At week 8, there were differences in systolic BP (-17+/-9 mm Hg, NUCCA versus -3+/-11 mm Hg, placebo; P<0.0001) and diastolic BP (-10+/-11 mm Hg, NUCCA versus -2+/-7 mm Hg; P=0.002). Lateral displacement of Atlas vertebra (1.0, baseline versus 0.04 degrees week 8, NUCCA versus 0.6, baseline versus 0.5 degrees , placebo; P=0.002). Heart rate was not reduced in the NUCCA group (-0.3 beats per minute, NUCCA, versus 0.5 beats per minute, placebo). No adverse effects were recorded. We conclude that restoration of Atlas alignment is associated with marked and sustained reductions in BP similar to the use of two-drug combination therapy.

Asthma management by preschool children and their families: a developmental framework

Sixty-one low-income, African-American mothers of preschool children with asthma were interviewed about asthma management. Additionally, 15 nurses provided information for a developmental schedule of asthma self-management activities. Most children had been diagnosed with asthma prior to age 18 months. Children participated in asthma management by 20 months, yet their mothers did not expect them to be able to manage their asthma by school age. Mothers expended considerable effort in coordinating asthma management with others. We suggest that asthma education with this population promote developmentally appropriate parent-child partnerships and effective involvement of family members and secondary settings.
