Abstract
INTRODUCTION This study aims to assess the association of operative time with the postoperative length of stay and unplanned return to the operating room in patients undergoing femoral to below knee popliteal bypasses, stratified by autologous vein graft or polytetrafluoroethylene (PTFE). MATERIALS AND METHODS A retrospective analysis of vascular quality initiative database (2003-2021). The selected patients were grouped into the following: vein bypass (group I) and PTFE (group II) patients. Each group was further stratified by a median split of operative time (i.e., 210 min for autologous vein and 155 min for PTFE) to study the outcomes. The outcomes were assessed by univariate and multivariate approach. RESULTS Of the 10,902 patients studied, 3570 (32.7%) were in the autologous vein group, while 7332 (67.3%) were in the PTFE group. Univariate analysis revealed autologous vein and PTFE graft recipients that had increased operative times were associated with a longer mean postoperative length of stay and a higher incidence of all-cause return to the operating room. In PTFE group, patients with prolonged operative times were also found to be associated with higher incidence of major amputation, surgical site infection, and cardiovascular events, along with loss of primary patency within a year. CONCLUSIONS For patients undergoing femoral to below knee popliteal bypasses using an autologous vein or PTFE, longer operative times were associated with inferior outcomes. Mortality was not found to be associated with prolonged operative time.

Abstract
Background Surgical treatment of symptomatic extracranial carotid stenosis is well established for preventing neurological events and should adhere to optimal quality standards. However, there is growing concern as to whether results of controlled trials are replicable in real-world settings. Objectives To assess a symptomatic carotid stenosis population that underwent surgery and its short-term outcomes in a real-world context at a professional training center. Methods Observational study using data collected from medical records from January 2012 to January 2023. Patients undergoing operations for other carotid diseases and with concomitant heart surgery were excluded. Results A total of 70 patients undergoing angioplasty or carotid endarterectomy were included. Population subsets undergoing angioplasty or endarterectomy were similar. Differences in anesthetic modality and a longer operative time in the carotid endarterectomy subgroup were statistically significant. There were 4 cases of stroke, only 3 of which (2 minor and 1 major) were related to the index lesion. Thus, the rate of major operation-related stroke was 1.43% and the rate of any lesion-related stroke was 4.29%. There was 1 case of AMI in the angioplasty group and there were no deaths in the sample. The overall rate of major adverse cardiovascular events was 5.71%. There were no statistical differences between the endarterectomy and angioplasty groups regarding the main outcomes. Conclusions The rates of outcomes of ischemic stroke, acute myocardial infarction, death, and major adverse cardiovascular events at this center are in line with the rates reported by randomized controlled trials, demonstrating the feasibility of carotid surgery in centers with teaching programs.

Abstract
BACKGROUND Metabolic syndrome (MetS) is a constellation of hypertension, insulin resistance, obesity, and dyslipidemia and is known to increase the risk of postoperative morbidity. This study aimed to assess the impact of MetS on stroke, myocardial infarction, mortality, and other complications following carotid endarterectomy (CEA). METHODS We analyzed data from the National Surgical Quality Improvement Program. Patients undergoing elective CEA between 2011 and 2020 were included. Patients with American Society of Anesthesiologists status 5, preoperative length of stay (LOS) > 1 day, ventilator dependence, admission from nonhome location, and ipsilateral internal carotid artery stenosis of < 50% or 100% were excluded. A composite cardiovascular outcome for postoperative stroke, myocardial infarction, and mortality was generated. Multivariable binary logistic regression analyses were used to assess the association of MetS with the composite outcome and other perioperative complications. RESULTS We included 25,226 patients (3,613, 14.3% with MetS). MetS was associated with postoperative stroke, unplanned readmission, and prolonged LOS on bivariate analysis. On multivariable analysis, MetS was significantly associated with the composite cardiovascular outcome (1.320 [1.061-1.642]), stroke (1.387 [1.039-1.852]), unplanned readmission (1.399 [1.210-1.619]), and prolonged LOS (1.378 [1.024-1.853]). Other clinico-demographic factors associated with the cardiovascular outcome included Black race, smoking status, anemia, leukocytosis, physiologic risk factors, symptomatic disease, preoperative beta-blocker use, and operative time ≥ 150 min. CONCLUSIONS MetS is associated with cardiovascular complications, stroke, prolonged LOS, and unplanned readmissions following CEA. Surgeons should provide optimized care to this high-risk population and strive to reduce operative durations. LEVEL OF EVIDENCE: 3

Influence of Operative Time in the Results of Elective Endovascular Repair of Abdominal Aortic Aneurysms. Ann Vasc Surg 2022; 92:195-200. [PMID: 36566912 DOI: 10.1016/j.avsg.2022.12.077] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2022] [Revised: 11/21/2022] [Accepted: 12/14/2022] [Indexed: 12/24/2022]
Abstract
BACKGROUND A prolonged operative time (OT) is a well-recognized risk factor of postoperative complications after many open surgical procedures, although little is known about its impact in less-invasive endovascular procedures. We aimed to define the characteristics related to a prolonged OT in the endovascular treatment of aorto-iliac aneurysms (EVAR) and to evaluate the influence of OT on postoperative outcomes. METHODS Retrospective analysis of 284 consecutive patients (mean age 75 years, 95% male) who underwent an elective EVAR between 2000 and 2019. Operative characteristics related to OT and the impact of OT in postoperative results was studied using multiple lineal and logistic regression analyses, respectively. RESULTS The mean surgical time was 200 min. OT was associated (regression model) with the implantation of straight endografts (-38 min, P = 0.007), femoral artery surgery (+80 min, P < 0.001), hypogastric preservation procedures (+70 min, P < 0.001), associated peripheral arterial disease (+22 min, P = 0.013), general anesthesia (+34 min, P < 0.001), and aneurysm diameter (+9 min/cm, P = 0.002). During the postoperative period (<30 days or at discharge), 21% presented a complication and 2.8% died. OT was independently associated with a higher incidence of postoperative complications (odds ratio [OR] for each additional 30' of surgery = 1.34, P < 0.001), such as immediate (OR = 1.48, P = 0.003) and 6-month mortality (OR = 1.28, P = 0.025). CONCLUSIONS A prolonged OT is an independent risk factor for complications and mortality after EVAR. Surgeons must take this factor into consideration when defining the best therapeutic strategy for abdominal aortic aneurysms.

Abstract
Objective To analyze the risk factors associated with adverse events after carotid endarterectomy (CEA) in patients with unilateral severe carotid stenosis and contralateral occlusion. Methods Patients were recruited for CEA between August 2014 and February 2020. CEA was performed under general anesthesia. The carotid clamp time (CCT; long CCT: >20 min) is defined as the period between clamp-on and clamp-off for the stenotic carotid artery. The perioperative factors and postoperative adverse events were recorded. All patients were followed up for 1 year after CEA. Results Sixty subjects (65.8 ± 7.2 years; 54 males) were included. Patients with adverse events had significantly longer CCT than those without adverse events (60% vs. 40%, P = 0.013). Univariate logistic regression analysis showed that a history of diabetes was significantly associated with adverse events (OR, 0.190; 95% CI, 0.045–0.814; P = 0.025); long CCT was significantly associated with adverse events (OR, 8.500; 95% CI, 1.617–44.682; P = 0.011). After adjusting for confounding factors, including age, sex, BMI, diabetes, PSV, long CCT, non–use of shunt, and history of stroke or TIA, the associations between diabetes and adverse events (OR, 0.113; 95% CI, 0.013–0.959; P = 0.046) were statistically significant; the associations between long CCT and adverse events (OR, 1.301; 95% CI, 1.049–1.613; P = 0.017) were statistically significant. Conclusions A longer carotid clamp time (>20 min) and a history of diabetes may increase the risk of adverse events in patients with unilateral severe carotid stenosis and contralateral occlusion after CEA. With good preoperative evaluation and intraoperative monitoring, the use of shunts may not be needed intraoperatively in patients with unilateral severe carotid stenosis and contralateral occlusion.

Abstract
BACKGROUND An increased operative time (OT) has been associated with a higher rate of adverse outcomes after several surgical procedures although scarce evidence exists for infrainguinal bypass surgery (IBS) and its impact beyond the postoperative period. The aim of this study was to define surgical characteristics related to a prolonged OT in IBS for chronic limb threatening ischemia and its influence on postoperative and 1-year outcomes. MATERIALS AND METHODS Retrospective study of 249 consecutive patients (mean age 72.4 years, 73.1% male) undergoing IBS for CLI between 2008 and 2018. The characteristics related to the duration of surgery and its impact on outcome were assessed with a multiple linear regression and a multivariate logistic regression, respectively. RESULTS Interventions associated with a prolonged OT included the bypass to a below-the-knee artery (additional 36 min, p = 0.002), the need for an alternative vein or a hybrid PTFE-vein graft (additional 37 min, p = 0.02) and inflow associated procedures (additional 47 min, p < 0.001). OT was associated with a higher rate of postoperative complications (OR for each additional 30 min 1.123, 95% CI 1.021-1.234) and need for a sociosanitary facility at discharge (OR 1.143, 95% CI 1.033-1.265). At 1-year of follow-up, OT was related to a higher major amputation rate (OR 1.201, 95% CI 1.036-1.393) and non-significantly to mortality (OR 1.125, 95% CI 0.999-1.268). CONCLUSIONS A prolonged OT is a risk factor for adverse outcomes after IBS that extends beyond the immediate postoperative period. Further research is needed to evaluate how an expected high OT might influence decision-making.

Carotid endarterectomy with concomitant distal endovascular intervention is associated with increased rates of stroke and death. J Vasc Surg 2020; 73:960-967.e1. [PMID: 32707384 DOI: 10.1016/j.jvs.2020.07.062] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2020] [Accepted: 07/08/2020] [Indexed: 11/20/2022]
Abstract
OBJECTIVE Carotid endarterectomy (CEA) with concomitant distal endovascular intervention (CEA+D) is infrequently necessary but has often been used as a salvage maneuver when complications occur during CEA. The present study aimed to determine whether preoperative risk factors associated with CEA requiring CEA+D exist and to evaluate the outcomes compared with isolated CEA. METHODS The Vascular Quality Initiative CEA registry was used to identify patients who had undergone CEA or CEA+D for asymptomatic or symptomatic carotid stenosis from 2013 to 2019. Data regarding distal intervention included whether angioplasty or stenting of the distal internal carotid artery (ICA) and/or bifurcation had been required. However, information regarding the indication or whether the intervention had been planned was not included. The χ2 test and analysis of variance were used to evaluate the categorical and continuous perioperative variables. Variables with P < .20 on univariate analysis were included in the multivariable analysis to assess for preoperative predictors of the need for CEA+D and the association with perioperative stroke. RESULTS From 2013 to 2019, 327 CEA+D cases were identified and compared with 105,192 isolated CEA cases. The CEA+D patients were more likely to have undergone previous ipsilateral CEA (CEA, 1.8%; CEA+D, 4.9%; P < .01) and contralateral ICA occlusion (CEA, 4.6%; CEA+D, 11.0%; P < .01) but were less likely to have had ipsilateral stenosis ≥70% (CEA, 88.3%; CEA+D, 80.6%; P < .01). The preoperative factors associated with the need for CEA+D on multivariable analysis included previous peripheral vascular intervention, American Society of Anesthesiologists class ≥4, contralateral ICA occlusion, low-volume surgeon, and previous ipsilateral CEA. CEA+D was associated with significantly increased rates of stroke in both asymptomatic (CEA+D, 3.9%; CEA, 0.9%; P < .01) and symptomatic (CEA+D, 9.4%; CEA, 1.9%; P < .01) patients. CEA+D was associated with decreased rates of 30-day survival in both asymptomatic (CEA+D, 98.3%; CEA, 99.4%; P = .02) and symptomatic (CEA+D, 94.8%; CEA, 99.1%; P < .01) cohorts. On multivariable analysis, CEA+D remained significantly associated with stroke (odds ratio, 3.17; 95% confidence interval, 1.80-5.60; P < .01). Other factors significantly associated with perioperative stroke included procedure length >135 minutes, diabetes, hypertension, shunt for indication, symptomatic status, previous ipsilateral CEA, contralateral ICA occlusion, urgent or emergent procedure, intravenous medications for hemodynamic instability, and re-exploration at the initial operation. CONCLUSIONS Although markers of more significant cardiovascular disease burden were associated with the use of CEA+D, their power to predict CEA+D use was limited. In cases in which CEA+D was used, CEA+D was associated with significantly greater rates of perioperative stroke and mortality compared with isolated CEA for both asymptomatic and symptomatic patients, which could be useful for framing the expected outcomes after these procedures.

Abstract
Aims Previous studies have reported an increased risk for postoperative complications in the Medicaid population undergoing total hip arthroplasty (THA). These studies have not controlled for the surgeon’s practice or patient care setting. This study aims to evaluate whether patient point of entry and Medicaid status plays a role in quality outcomes and discharge disposition following THA. Methods The electronic medical record at our institution was retrospectively reviewed for all primary, unilateral THA between January 2016 and January 2018. THA recipients were categorized as either Medicaid or non-Medicaid patients based on a visit to our institution’s Hospital Ambulatory Care Center (HACC) within the six months prior to surgery. Only patients who had been operated on by surgeons (CML, JV, JDS, RS) with at least ten Medicaid and ten non-Medicaid patients were included in the study. The patients included in this study were 56.33% female, had a mean age of 60.85 years, and had a mean BMI of 29.14. The average length of follow-up was 343.73 days. Results A total of 426 hips in 403 patients were included in this study, with 114 Medicaid patients and 312 non-Medicaid patients. Medicaid patients had a significantly lower mean age (54.68 years (SD 12.33) vs 63.10 years (SD 12.38); p < 0.001), more likely to be black or ‘other’ race (27.19% vs 13.46% black; 26.32% vs 12.82% other; p < 0.001), and more likely to be a current smoker (19.30% vs 9.29%; p = 0.001). After adjusting for patient risk factors, there was a significant Medicaid effect on length of stay (LOS) (rate ratio 1.129, 95% confidence interval (CI) 1.048 to 1.216; p = 0.001) and facility discharge (odds ratio 2.010, 95% CI 1.398 to 2.890; p < 0.001). There was no Medicaid effect on surgical time (exponentiated β coefficient 1.015, 95% CI 0.995 to 1.036; p = 0.136). There was no difference in 30-day readmission, 90-day readmission, 30-day infections, 90-day infections, and 90-day mortality between the two groups. Conclusion After controlling for patient variables, there was a statistically significant Medicaid effect on LOS and facility discharge. These results indicate that clinically similar outcomes can be achieved for Medicaid patients; however, further work is needed on maximizing social support and preoperative patient education with a focus on successful home discharge.

Abstract
OBJECTIVE Smoking is a significant modifiable risk factor in the pathogenesis of carotid artery disease and has been shown to be a predictor of worse outcomes after vascular surgery. However, the effect of active smoking on outcomes of patients undergoing carotid endarterectomy is unknown. This study analyzed the outcomes of carotid endarterectomy by smoking status in a large national database. METHODS The American College of Surgeons National Surgical Quality Improvement Program targeted carotid endarterectomy files (2011-2017) were reviewed. Patients were stratified according to smoking status, and outcomes were compared using propensity score matching (1:1) based on preoperative characteristics. RESULTS During the study period, 26,293 patients underwent carotid endarterectomy, with 19,282 (73.34%) nonsmokers and 7011 (26.66%) smokers. Smokers were more likely to be younger, to have chronic obstructive pulmonary disease, to have a symptomatic presentation, and to have higher anatomic risk (P < .05). Smokers were also more likely to have emergent surgery, to have general anesthesia, and to be reintubated (P < .05). After propensity matching, 5354 nonsmokers were matched with 5354 smokers who underwent carotid endarterectomy. Smokers were at significantly higher risk for death, with an odds ratio of 1.93 (confidence interval, 1.18-3.13). CONCLUSIONS Smokers are at increased risk for death after carotid endarterectomy compared with matched counterparts. Smoking should be considered an important risk factor for worse outcomes, and patients should be strongly counseled on the importance of smoking cessation before undergoing carotid endarterectomy.

Abstract
The advance of therapies to reduce the stroke impact of asymptomatic carotid artery stenosis has proved difficult over the last decade. Disagreement concerning the underlying randomized control trials has limited entry into the care arena of endovascular therapies. Recently, advances in percutaneous therapies for carotid artery disease have been reported and provide a substantial database supporting the further incorporation of endovascular-based therapies in patients who need revascularization and meet selection criteria. With a second randomized control trial now published, it is time for a re-evaluation of endovascular therapy as a component of carotid artery care. This review describes the advances in the field in the last 5 years, clarifying the current position of these therapies in the care of the patient with asymptomatic carotid artery disease.

[PMID: 31917229 DOI: 10.1016/j.avsg.2019.12.033] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2019] [Revised: 09/30/2019] [Accepted: 12/19/2019] [Indexed: 01/30/2023]
Abstract
BACKGROUND Anesthesia modalities for carotid endarterectomy continue to vary nationally. We evaluated and compared short-term outcomes after carotid endarterectomy with general anesthesia (GA) and regional anesthesia (RA) in both symptomatic and asymptomatic patients. METHODS The 2011-2015 American College of Surgeons National Surgical Quality Improvement Program Participant Use Data Files (PUFs) with merged Vascular Procedure-Targeted PUFs for carotid endarterectomy were queried for patients undergoing carotid endarterectomy. Postoperative complications, mortality, and hospital length of stay in patients undergoing GA or RA were compared. RESULTS A total of 14,447 patients were evaluated: 12,389 (85.7%) with GA and 2,058 (14.3%) with RA. The use of GA was inversely associated with patients' age (88.0% in patients aged 22-64 years vs. 83.4% in patients aged ≥80 years, P < 0.0001) and with symptomatic presentation (odds ratio [OR] = 1.25; 95% confidence interval [CI]: 1.13-1.38). There were no differences between GA and RA for in-hospital mortality, 30-day mortality, or postoperative complications of transient ischemic attack, stroke, bleeding, acute renal failure, or restenosis. However, rates of cranial nerve injury were significantly higher in GA than in RA (2.9% vs. 1.7%, respectively; P < 0.002) and confirmed by multivariable analysis (OR = 1.68; 95% CI: 1.19-2.39). Total operative time was also longer for GA than for RA (median: 115 minutes; Interquartile range (IQR): 89-145 versus median: 93 minutes; IQR: 76-119, respectively; P < 0.0001). Hospital length of stay was greater in GA than in RA (median: 1 day; IQR 1-2 vs. median: 1 day; IQR 1-1, respectively; P < 0.0001), as were 30-day readmission rates (6.7% vs. 5.4%, respectively; P = 0.02). CONCLUSIONS Iatrogenic nerve injury is a feared complication of carotid endarterectomy, especially in elective asymptomatic patients. RA reduces the rate of cranial nerve injury compared with GA. RA is also not inferior to GA for postoperative complications with the benefit of shorter operative times, lengths of hospital stay, and decreased 30-day readmission rates. Consideration should be given to more widespread adoption of this underused anesthesia modality.

Abstract
BACKGROUND Anastomotic leak is the most common major complication after esophagectomy. We investigated the 2016 American College of Surgeons National Surgical Quality Improvement Program esophagectomy targeted database to identify risk factors for anastomotic leak. METHODS Patients who underwent esophagectomy for cancer were included. Patients experiencing an anstomotic leak were identified, and univariate and multivariable logistic regression was performed to identify variables independently associated with anastomotic leak. RESULTS Of 915 patients included, 83% were male and the median age was 64 years. Patients with anastomotic leak more frequently had additional complications (87% vs 36%, P < .001). Rates of reoperation (64% vs 11%, P < .001) and mortality (8% vs 2%, P = .001) were higher in patients with anastomotic leak. After adjusting for patient and procedure characteristics, prolonged operative time (for each additional 30-minutes; adjusted odds ratios (AOR) 1.068, 95% CI, 1.022-1.115, P = .003), increased preoperative WBC count (for each 3000/µL increase; AOR 1.323, 95% CI, 1.048-1.670, P = .019), pre-existing diabetes (AOR 1.601, 95% CI, 1.012-2.534, P = .045), and perioperative transfusion (AOR 1.777, 95% CI, 1.064-2.965, P = .028) were independently associated with anastomotic leak. CONCLUSION Both patient and procedure-related factors are associated with anastomotic leak. Though frequently non-modifiable, these findings could facilitate risk stratification and early detection of anastomotic leak to reduce associated morbidity.

Fertil Steril 2019; 111:1252-1258.e1. [PMID: 30982607 DOI: 10.1016/j.fertnstert.2019.02.020] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2018] [Revised: 02/19/2019] [Accepted: 02/19/2019] [Indexed: 11/29/2022]
Abstract
OBJECTIVE(S) To determine the association of operative time (ORT) with perioperative morbidity and whether there is an ORT at which minimally invasive myomectomy becomes inferior to laparotomy. DESIGN Retrospective cohort study. SETTING Not applicable. PATIENT(S) Myomectomy cases identified by CPT code from 2005 to 2016. INTERVENTION(S) Cases were stratified and analyzed by surgical approach and 90-minute intervals. MAIN OUTCOME MEASURE(S) Thirty-day postoperative morbidity. RESULT(S) A total of 11,709 myomectomies were identified; 4,673 (39.9%) were minimally invasive, 6,997 (59.8%) were abdominal, and 39 (0.3%) were conversions. The incidence of complications significantly increased with ORT. After adjusting for confounders, mean ORT in minutes (95% confidence interval) was 113 (111-115) for abdominal, 156 (153-159) for minimally invasive, and 172 (148-200) for conversions. Despite shorter ORT, morbidity was greater in abdominal cases (16% vs. 5.7%), with the highest rates in converted cases (20.5%). The minimally invasive approach in general had lower odds of complications (odds ratio, 0.23; 95% confidence interval, 0.19-0.26). However, when minimally invasive surgery ORT reached ≥ 270 minutes, the odds of a composite complication variable increased compared with abdominal cases <90 minutes (odds ratio, 2.30; 95% confidence interval, 1.69-3.13). Of minimally invasive cases, 88% were completed in <270 minutes. CONCLUSION(S) ORT was predictive of complications for both minimally invasive and abdominal myomectomies. Despite longer ORTs, minimally invasive procedures generally had superior 30-day outcomes up to 270 minutes. Careful patient counseling and preparation to increase surgical efficiency should be prioritized for either approach.

Abstract
Carotid endarterectomy (CEA) is a surgical intervention that may prevent stroke in asymptomatic and symptomatic patients. Our aim was to examine the microsurgical anatomy of carotid artery and other related neurovascular structures to summarize the CEA that is currently applied in ideal conditions. The upper necks of 2 adult cadavers (4 sides) were dissected using ×3 to ×40 magnification. The common carotid artery, external carotid artery (ECA), and internal carotid artery were exposed and examined. The surgical steps of CEA were described using 3-D cadaveric photos and computed tomography angiographic pictures obtained with help of OsiriX imaging software program. Segregating certain neurovascular and muscular structures in the course of CEA significantly increased the exposure. The division of facial vein allowed for internal jugular vein to be mobilized more laterally and dividing the posterior belly of digastric muscle resulted in an additional dorsal exposure of almost 2 cm. Isolating the ansa cervicalis that pulls hypoglossal nerve inferiorly allowed hypoglossal nerve to be released safely medially. The locations of the ECA branches alter depending on their anatomical variations. The hypoglossal nerve, glossopharyngeal nerve, and accessory nerve pierce the fascia of the upper part of the carotid sheath and they are vulnerable to injury because of their distinct courses along the surgical route. Surgical exposure in CEA requires meticulous dissection and detailed knowledge of microsurgical anatomy of the neck region to avoid neurovascular injuries and to determine the necessary surgical maneuvers in cases with neurovascular variations.

Reframing the Biological Basis of Neuroprotection Using Functional Genomics: Differentially Weighted, Time-Dependent Multifactor Pathogenesis of Human Ischemic Brain Damage. Front Neurol 2018; 9:497. [PMID: 29997569 PMCID: PMC6028620 DOI: 10.3389/fneur.2018.00497] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2017] [Accepted: 06/07/2018] [Indexed: 12/18/2022] Open
Abstract
Background: Neuroprotection studies are generally unable to demonstrate efficacy in humans. Our specific hypothesis is that multiple pathophysiologic pathways, of variable importance, contribute to ischemic brain damage. As a corollary to this, we discuss the broad hypothesis that a multifaceted approach will improve the probability of efficacious neuroprotection. But to properly test this hypothesis the nature and importance of the multiple contributing pathways needs elucidation. Our aim is to demonstrate, using functional genomics, in human cardiac surgery procedures associated with cerebral ischemia, that the pathogenesis of perioperative human ischemic brain damage involves the function of multiple variably weighted proteins involving several pathways. We then use these data and literature to develop a proposal for rational design of human neuroprotection protocols. Methods: Ninety-four patients undergoing deep hypothermic circulatory arrest (DHCA) and/or aortic valve replacement surgery had brain damage biomarkers, S100β and neurofilament H (NFH), assessed at baseline, 1 and 24 h post-cardiopulmonary bypass (CPB) with analysis for association with 92 single nucleotide polymorphisms (SNPs) (selected by co-author WAK) related to important proteins involved in pathogenesis of cerebral ischemia. Results: At the nominal significance level of 0.05, changes in S100β and in NFH at 1 and 24 h post-CPB were associated with multiple SNPs involving several prospectively determined pathophysiologic pathways, but were not individually significant after multiple comparison adjustments. Variable weights for the several evaluated SNPs are apparent on regression analysis and, notably, are dissimilar related to the two biomarkers and over time post CPB. Based on our step-wise regression model, at 1 h post-CPB, SOD2, SUMO4, and GP6 are related to relative change of NFH while TNF, CAPN10, NPPB, and SERPINE1 are related to the relative change of S100B. At 24 h post-CPB, ADRA2A, SELE, and BAX are related to the relative change of NFH while SLC4A7, HSPA1B, and FGA are related to S100B. Conclusions: In support of the proposed hypothesis, association SNP data suggest function of specific disparate proteins, as reflected by genetic variation, may be more important than others with variation at different post-insult times after human brain ischemia. Such information may support rational design of post-insult time-sensitive multifaceted neuroprotective therapies.

Abstract
Quality improvement is at the heart of practice of anesthesiology. Objective data are critical for any quality improvement initiative; when possible, a combination of process, outcome, and balancing metrics should be evaluated to gauge the value of an intervention. Quality improvement is an ongoing process; iterative reevaluation of data is required to maintain interventions, ensure continued effectiveness, and continually improve. Dashboards can facilitate rapid analysis of data and drive decision making. Large data sets can be useful to establish benchmarks and compare performance against other providers, practices, or institutions. Audit and feedback strategies are effective in facilitating positive change.
