a b s t r a c tBackground: With the shift of our healthcare system toward a value-based system of reimbursement, complications such as surgical site infections (SSI) may not be reimbursed.The purpose of our study was to investigate the costs and risk factors of SSI for orthopedic trauma patients.Methods: Through retrospective analysis, 1819 patients with isolated fractures were identified. Of those, 78 patients who developed SSIs were compared to 78 uninfected control patients. Patients were matched by fracture location, type of fracture, duration of surgery, and as close as possible to age, year of surgery, and type of procedure. Costs for treatment during primary hospitalization and initial readmission were determined and potential risk factors were collected from patient charts. A Wilcoxon test was used to compare the overall costs of treatment for case and control patients. Costs were further broken down into professional fees and technical charges for analysis. Risk factors for SSIs were analyzed through a chi-squared analysis.Results: Median cost for treatment for patients with SSIs was $108,782 compared to $57,418 for uninfected patients ( p < 0.001). Professional fees and technical charges were found to be significantly higher for infected patients. No significant risk factors for SSIs were determined.Conclusions: Our findings indicate the potential for financial losses in our new healthcare system due to uncompensated care. SSIs nearly double the cost of treatment for orthopedic trauma patients. There is no single driver of these costs. Reducing postoperative stay may be one method for reducing the cost of treating SSIs, whereas quality management programs may decrease risk of infection.
The incidence of VTE after cosmetic procedures is relatively low. However, the risk increases with combined procedures as well as with particular body areas, most notably trunk and extremities. Equally, significant patient risk factors exist, including BMI and age.
Rhytidectomy is a very safe procedure in the hands of board-certified plastic surgeons. Hematoma and infection are the most common major complications. Male gender, BMI ≥ 25, and combined procedures are independent risk factors. LEVEL OF EVIDENCE 2: Risk.
Background
Specific details about cardiovascular complications, especially arrhythmias, related to the coronavirus disease of 2019 (COVID‐19) are not well described.
Objective
We sought to evaluate the incidence and predictive factors of cardiovascular complications and new‐onset arrhythmias in Black and White hospitalized COVID‐19 patients and determine the impact of new‐onset arrhythmia on outcomes.
Methods
We collected and analyzed baseline demographic and clinical data from COVID‐19 patients hospitalized at the Tulane Medical Center in New Orleans, Louisiana, between March 1 and May 1, 2020.
Results
Among 310 hospitalized COVID‐19 patients, the mean age was 61.4 ± 16.5 years, with 58,7% females, and 67% Black patients. Black patients were more likely to be younger, have diabetes and obesity. The incidence of cardiac complications was 20%, with 9% of patients having new‐onset arrhythmia. There was no significant difference in cardiovascular outcomes between Black and White patients. A multivariate analysis determined age ≥60 years to be a predictor of new‐onset arrhythmia (OR = 7.36, 95% CI [1.95;27.76], p = .003). D‐dimer levels positively correlated with cardiac and new‐onset arrhythmic event. New onset atrial arrhythmias predicted in‐hospital mortality (OR = 2.99 95% CI [1.35;6.63], p = .007), a longer intensive care unit length of stay (mean of 6.14 days, 95% CI [2.51;9.77], p = .001) and mechanical ventilation duration(mean of 9.08 days, 95% CI [3.75;14.40], p = .001).
Conclusion
Our results indicate that new onset atrial arrhythmias are commonly encountered in COVID‐19 patients and can predict in‐hospital mortality. Early elevation in D‐dimer in COVID‐19 patients is a significant predictor of new onset arrhythmias. Our finding suggest continuous rhythm monitoring should be adopted in this patient population during hospitalization to better risk stratify hospitalized patients and prompt earlier intervention.
NAD(+) plays essential roles in cellular energy homoeostasis and redox state, functioning as a cofactor along the glycolysis and citric acid cycle pathways. Recent discoveries indicated that, through the NAD(+)-consuming enzymes, this molecule may also be involved in many other cellular and biological outcomes such as chromatin remodelling, gene transcription, genomic integrity, cell division, calcium signalling, circadian clock and pluripotency. Poly(ADP-ribose) polymerase 1 (PARP1) is such an enzyme and dysfunctional PARP1 has been linked with the onset and development of various human diseases, including cancer, aging, traumatic brain injury, atherosclerosis, diabetes and inflammation. In the present study, we showed that overexpressed acyl-CoA-binding domain containing 3 (ACBD3), a Golgi-bound protein, significantly reduced cellular NAD(+) content via enhancing PARP1's polymerase activity and enhancing auto-modification of the enzyme in a DNA damage-independent manner. We identified that extracellular signal-regulated kinase (ERK)1/2 as well as de novo fatty acid biosynthesis pathways are involved in ACBD3-mediated activation of PARP1. Importantly, oxidative stress-induced PARP1 activation is greatly attenuated by knocking down the ACBD3 gene. Taken together, these findings suggest that ACBD3 has prominent impacts on cellular NAD(+) metabolism via regulating PARP1 activation-dependent auto-modification and thus cell metabolism and function.
There is a significant difference in LOS based on operative approach for sacral fracture patients. Given similar complications and readmission rates, we recommend a percutaneous approach.
