    Association of Early Beta-Blocker Exposure and Functional Outcomes in Critically Ill Patients With Moderate to Severe Traumatic Brain Injury: A Transforming Clinical Research and Knowledge in Traumatic Brain Injury Study.
    (Critical care explorations, 2023-09) Kelly-Hedrick, Margot; Liu, Sunny Yang; Temkin, Nancy; Barber, Jason; Komisarow, Jordan; Manley, Geoffrey; Ohnuma, Tetsu; Colton, Katharine; Treggiari, Miriam M; Monson, Eric E; Vavilala, Monica S; Grandhi, Ramesh; Laskowitz, Daniel T; Mathew, Joseph P; Hernandez, Adrian; James, Michael L; Raghunathan, Karthik; Goldstein, Ben; Markowitz, Amy J; Krishnamoorthy, Vijay

    Objectives

    We aimed to 1) describe patterns of beta-blocker utilization among critically ill patients following moderate-severe traumatic brain injury (TBI) and 2) examine the association of early beta-blocker exposure with functional and clinical outcomes following injury.

    Design

    Retrospective cohort study.

    Setting

    ICUs at 18 level I, U.S. trauma centers in the Transforming Clinical Research and Knowledge in TBI (TRACK-TBI) study.

    Patients

    Greater than or equal to 17 years enrolled in the TRACK-TBI study with moderate-severe TBI (Glasgow Coma Scale of <13) were admitted to the ICU after a blunt TBI.

    Interventions

    None.

    Measurements

    Primary exposure was a beta blocker during the first 7 days in the ICU, with a primary outcome of 6-month Glasgow Outcome Scale-Extended (GOSE). Secondary outcomes included: length of hospital stay, in-hospital mortality, 6-month and 12-month mortality, 12-month GOSE score, and 6-month and 12-month measures of disability, well-being, quality of life, and life satisfaction.

    Main results

    Of the 450 eligible participants, 57 (13%) received early beta blockers (BB+ group). The BB+ group was on average older, more likely to be on a preinjury beta blocker, and more likely to have a history of hypertension. In the BB+ group, 34 participants (60%) received metoprolol only, 19 participants (33%) received propranolol only, 3 participants (5%) received both, and 1 participant (2%) received atenolol only. In multivariable regression, there was no difference in the odds of a higher GOSE score at 6 months between the BB+ group and BB- group (odds ratio = 0.86; 95% CI, 0.48-1.53). There was no association between BB exposure and secondary outcomes.

    Conclusions

    About one-sixth of subjects in our study received early beta blockers, and within this group, dose, and timing of beta-blocker administration varied substantially. No significant differences in GOSE score at 6 months were demonstrated, although our ability to draw conclusions is limited by overall low total doses administered compared with prior studies.

    Clinical outcomes and proximal junctional failure in adult spinal deformity patients corrected to normative alignment versus functional alignment.
    (Journal of neurosurgery. Spine, 2023-07) Protopsaltis, Themistocles S; Ani, Fares; Soroceanu, Alexandra; Lafage, Renaud; Kim, Han Jo; Balouch, Eaman; Norris, Zoe; Smith, Justin S; Daniels, Alan H; Klineberg, Eric O; Ames, Christopher P; Hart, Robert; Bess, Shay; Shaffrey, Christopher I; Schwab, Frank J; Lenke, Lawrence G; Lafage, Virginie; Gupta, Munish C

    Objective

    The objective of this study was to explore the rate of proximal junctional failure (PJF) and functional outcomes of normative alignment goals compared with alignment targets based on age-appropriate physical function.

    Methods

    Baseline relationships between age, pelvic incidence (PI), and a component of the T1 pelvic angle (TPA) within the fusion were analyzed in adult spinal deformity (ASD) patients and compared with those of asymptomatic patients. Linear regression modeling was used to determine alignment based on PI and age in asymptomatic patients (normative alignment), and in ASD patients, alignment corresponding to age-appropriate functional status (functional alignment). A cohort of 288 ASD patients was split into two groups based on whether the patient was closer to their normative or functional alignment goal at their 6-week postoperative radiographic follow-up. The rates of proximal junctional kyphosis (PJK) and PJF were determined for each cohort.

    Results

    In the 288 ASD patients included in this pre- to postoperative analysis, there was no difference in baseline alignment or health-related quality of life (HRQOL) between the normative alignment and functional alignment groups. At 6 weeks, patients with normative alignment had a smaller TPA (4.45° vs 14.1°) and PI minus lumbar lordosis (-7.24° vs 7.4°) (both p < 0.0001) and higher PJK (40% vs 27.2%, p = 0.03) and PJF (17% vs 6.8%, p = 0.008) rates than patients with functional alignment.

    Conclusions

    Correction in ASD patients to normative alignment resulted in higher rates of PJK and PJF without improvements in HRQOL. Correction in ASD patients to functional alignment that mirrors the physical function of their age-matched asymptomatic peers is recommended.
