Key Clinical MessagePulmonary function tests such as flow‐volume loops and reconstructive radiological imaging may aid the detection of large airway obstruction prior to corrective surgery for severe scoliosis. Intraoperative use of halo‐gravity traction may help to reduce the severity of the scoliosis, and thus the extrinsic compression or torsion of the airways.
vitamin K and PIVKAII levels if they consumed a minimum of 200 mls prescribed sip feed or 400-800 mls gastrostomy feed daily.16/16 (100%) patients took a multivitamin/mineral supplement; none contained vitamin K. Summary The prevalence of vitamin K deficiency is 37.5% in this cohort. Patients whom were not consuming gastrostomy/ sip feeds of at least 200 mls daily were at greatest risk of vitamin K deficiency. Patients on a micronutrient supplement remain at risk of vitamin K deficiency, as most contain no vitamin K. Prescribing a vitamin/mineral supplement that contains vitamin K is prudent.12-week supplementation of oral vitamin K (5 mg/day for 1-10 years and 10 mg/day for 12-17 years) adequately improved stores.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
