Association Between Modified Frailty Index and Postoperative Outcomes of Tracheostomies.

OBJECTIVE: The 5-item modified frailty index (mFI-5) has been used to stratify patients based on the risk of postoperative complications in several surgical procedures but has not yet been done in tracheostomies. This study investigates the association between the mFI-5 score and tracheostomy complications. STUDY DESIGN: Retrospective database review. SETTING: United States hospitals. METHODS: The National Surgical Quality Improvement Program database was queried for tracheostomy patients between 2005 and 2018. The mFI-5 was calculated for each patient by assigning 1 point for each of the following comorbidities: diabetes mellitus, hypertension, congestive heart failure, chronic obstructive pulmonary disease, and functionally dependent health status. Univariate and multivariable analyses were conducted to determine associations between the mFI-5 score and postoperative complications. RESULTS: A total of 4438 patients undergoing tracheostomies were queried and stratified into the following groups: mFI = 0 (N = 1741 [39.2%], mFI = 1 (N = 1720 [38.8%]), mFI = 2 (N = 726 [16.4%]), and mFI of 3 or higher (N = 251 [5.7%]). Univariate analysis showed that patients with higher mFI-5 scores had a greater proportion of smoking, dyspnea, obesity, steroid use, emergency cases, complications, reoperations, and mortality (P < .001). Multivariable analyses found associations between mFI-5 score and any complication (odds ratio [OR]: 1.49, 95% confidence interval [CI]: 1.03-2.16, P = .035), mortality (OR: 2.32, 95% CI: 1.15-4.68, P = .019), and any medical complication (OR: 2.75, 95% CI: 1.88-4.02, P < .001). CONCLUSION: This study suggests an association between the mFI-5 score and postoperative complications in tracheostomies. mFI-5 score can be used to stratify tracheostomy patients by operative risk.

Outcomes of humeral osteotomies versus soft-tissue procedures in secondary surgical procedures for neonatal brachial plexus palsy: a meta-analysis.

Secondary surgical procedures can be used in brachial plexus birth injury to correct shoulder movement imbalances. This study compares outcomes of the two secondary surgical procedure types: humeral osteotomies and soft tissue procedures. Outcome measures assessed included active and passive internal and external rotation, active and passive abduction and adduction, active and passive flexion and extension, percentage of the humeral head anterior to the middle glenoid fossa, glenoid version, and Mallet Score. Nineteen full-text articles were included in the analysis. Humeral osteotomies resulted in a loss of internal rotation postoperatively (-15.94°). Active internal rotation was not evaluated for soft tissue procedures. All other assessed outcomes were improved postoperatively for bony and soft tissue procedures. Bony procedures exhibited a greater degree of active external rotation postoperatively when compared to soft tissue procedures (+67° vs. +40°). Both bony and soft tissue procedures Improve shoulder function in children with neonatal brachial plexus palsy, however, soft tissue procedures showed greater consistency in outcomes. Level of Evidence: IV.

Does a Modified Frailty Index Predict 30-day Complications After Long-Bone Nonunion or Malunion Surgery?

OBJECTIVE: To assess the ability of a modified frailty index (mFI-5) score, which includes the presence of congestive heart failure, hypertension, chronic obstructive pulmonary disease, diabetes, and nonindependent functional status, and to identify patients at increased risk of complications after surgical treatment of long-bone nonunions/malunions. DESIGN: Retrospective. SETTING: Hospitals participating in the 2005-2018 American College of Surgeons National Surgical Quality Improvement Program. PATIENTS/PARTICIPANTS: Patients in the American College of Surgeons National Surgical Quality Improvement Program database with upper extremity and lower extremity fractures were enrolled. INTERVENTION: Surgical repair of nonunions/malunions of upper and lower extremity long bones. MAIN OUTCOME MEASURE: Postoperative complications after long-bone nonunion/malunion surgery. RESULTS: Respective univariate analysis of the 2964 UE [1786 (60.3%) with mFI-5 of 0 and 386 (13.0%) with mFI-5 ≥2] and 3305 LE [1837 (55.6%) with mFI-5 of 0 and 498 (15.1%) with mFI-5 ≥2] showed that increasing mFI-5 score was associated with medical complications, extended longer length of stay, adverse discharge, and readmission. Binomial logistic regression showed that UE patients with mFI-5 ≥2 had increased risk of wound complications [odds ratio (OR) 2.512, 95% (confidence interval) CI: 1.037-6.086, P = 0.041), adverse discharge (OR 1.735, 95% CI: 1.204-2.499, P = 0.003), and unplanned readmission (OR 2.102, 95% CI: 1.038-4.255, P = 0.039), while LE patients with mFI-5 ≥2 had an increased risk of medical complications (OR 1.847, 95% CI: 1.307-2.610, P = 0.001), cumulative morbidity (OR 1.835, 95% CI: 1.342-2.510, P < 0.001), extended longer length of stay (OR 1.809, 95% CI: 1.233-2.654, P = 0.002), and adverse discharge (OR 1.841, 95% CI: 1.394-2.432, P < 0.001). CONCLUSIONS: mFI-5 score ≥2 is associated with significant increase in postoperative complications after surgical repair of long-bone nonunions/malunions. LEVEL OF EVIDENCE: Prognostic Level III.

An analysis of lactate dehydrogenase (LDH) levels in advanced stage IV melanoma of the skin: prognostic capabilities and demographic variability.

Despite its limitations, in part due to decreased specificity in advanced disease, serum lactate dehydrogenase (LDH) is one of few serum factors used in cancer staging. This study quantifies the predictive capabilities of LDH in stage IV melanoma of the skin and explores the validity of suggested demographic discrepancies which may exist in its use. The 1975-2017 Surveillance Epidemiology and End Results (SEER) database was queried for stage IV cutaneous melanoma cases. Demographic characteristics were compared between LDH groups using chi-square and t tests. Subsequent Cox multivariable regression was performed to assess survival differences. 334 cases of stage IV cutaneous melanoma (average age: 63.0 years) with measured serum LDH levels were identified. Of these patients, 150 (44.9%) had normal LDH, 112 (33.5%) had LDH < 1.5 × upper limit of normal (ULN), 57 (17.1%) had LDH 1.5-10 × ULN, and 15 (4.5%) had LDH > 10 × ULN. Lower incomes were associated with higher LDH; individuals with incomes < $50,000 had the greatest proportion of LDH 10 × ULN (19.2%; p = 0.0031). LDH > 10 × ULN also had the lowest proportion of White patients (p = 0.04). On Cox multivariable survival analysis, increasing LDH levels showed increased risk of death (LDH < 1.5 × ULN: HR = 2.05, p = 0.01; LDH 1.5-10 × ULN: HR = 1.46, p < 0.001; LDH > 10 × ULN: HR = 5.91, p < 0.001). This study reaffirms the utility of LDH as a significant predictor of mortality with incremental severity, suggesting possible use for mortality projections. We note that Black patients and those with lower incomes may be more likely to have an elevated LDH. Older age groups and presence of ulceration among patients with stage IV melanoma were also associated with a greater risk of mortality.

Association between atherosclerotic cardiovascular disease risk score estimated by pooled cohort equation and coronary plaque burden as assessed by NaF-PET/CT.

Pooled Cohort Equations (PCE) combines metabolic and non-metabolic parameters to predict the 10-year risk of atherosclerotic cardiovascular disease (ASCVD). Therefore, we hypothesize that ASCVD risk score is correlated to global cardiac microcalcification, as assessed by 18F-sodium fluoride-positron emission tomography/computed tomography (NaF-PET/CT). Sixty-one individuals (53.4±8.9 years, 32 females, 100% Caucasian) without known ASCVD underwent NaF-PET/CT imaging. Global cardiac average SUVmean (aSUVmean), also known as the Alavi-Carlsen Calcification Score, was calculated across manually defined regions of interest on each axial slice for each individual. The 10-year ASCVD risk score was determined for each individual using the PCE as per ACC/AHA guidelines, and then individuals were categorized into low-, borderline-, intermediate-, and high-risk groups based on their score. Linear regression analysis was applied to compare each individual's ASCVD score and aSUVmean. Global cardiac aSUVmean stratified by groups estimated by 10-year ASCVD risk score were 0.67±0.09 for low risk (n=32), 0.70±0.11 for borderline risk (n=10), 0.72±0.10 for intermediate risk (n=17), and 0.78±0.10 for high risk (n=2). ASCVD risk score was significantly correlated to aSUVmean (r=0.27, P=0.03). This is among the first studies to compare ASCVD risk scores to cardiac plaque burden as assessed by NaF-PET/CT. Large, prospective studies are needed to further investigate the potential of NaF uptake in ASCVD.
