[PMID: 38317783 PMCID: PMC10840019 DOI: 10.1002/oto2.114] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Revised: 12/21/2023] [Accepted: 01/07/2024] [Indexed: 02/07/2024] Open
Abstract
Objective Albumin is considered to be a surrogate marker for inflammation and nutritional status. Levels usually decrease after surgery but little is known about the predictive value of preoperative albumin levels in patients undergoing thyroidectomy. This study aimed to investigate the 30-day incidence of postoperative outcomes in thyroidectomy patients with and without preoperative hypoalbuminemia. Study Design Retrospective cohort study. Setting TriNetX Database. Methods TriNetX, a federated deidentified database, was retrospectively queried to identify patients who underwent thyroidectomy. Postoperative outcomes within 30 days of thyroidectomy, based on International Classification of Disease, 10th Revision and Current Procedural Terminology codes, in patients with preoperative hypoalbuminemia (≤3.4 g/dL) (cohort 1) were analyzed and compared to patients without hypoalbuminemia (cohort 2). Results After propensity score matching, 2398 patients were identified in each cohort. Hypoalbuminemia patients were more likely to have postoperative pneumonia (odds ratio, OR: 3.472, 95% confidence interval, CI [2.016-5.978]), acute renal failure (OR: 3.872, 95% CI [2.412-6.217]), venous thromboembolism (OR: 1.766, 95% CI [1.016-2.819]), and surgical site infection (OR: 2.353, 95% CI [1.282-4.32]). Rates of recurrent laryngeal nerve injury were comparable between cohorts. Conclusion Patients undergoing thyroidectomy with preoperative hypoalbuminemia have a higher prevalence of postoperative complications compared to patients without preoperative hypoalbuminemia. While not routinely assessed, preoperative evaluation of serum albumin levels may help guide expectations and optimal management of thyroidectomy patients.

Obesity Paradox for Postoperative Mortality in Young Chinese Patients Undergoing Craniotomy for Brain Tumor Resection. J Neurosurg Anesthesiol 2023:00008506-990000000-00076. [PMID: 37550895 DOI: 10.1097/ana.0000000000000932] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2022] [Accepted: 06/29/2023] [Indexed: 08/09/2023]
Abstract
BACKGROUND There is little evidence regarding the association of body mass index (BMI) with postoperative mortality after craniotomy, especially in the Asian population. Our study aimed to explore the association between BMI and postoperative 30-day mortality in Chinese patients undergoing craniotomy for brain tumor resection. METHODS This large retrospective cohort study, Supplemental Digital Content 9, http://links.lww.com/JNA/A634 collected data from 7519 patients who underwent craniotomy for brain tumor resection. On the basis of the World Health Organization obesity criteria for Asians, included patients were categorized as underweight (<18.5 kg/m2), normal weight (18.5 to 22.9 kg/m2), overweight (23to 24.9 kg/m2), obese I (25 to 29.9 kg/m2), and obese II (≥30 kg/m2). We used a multivariable logistic regression model to explore the association between different BMI categories and 30-day postoperative mortality. In addition, we also conducted stratified analyses based on age and sex. RESULTS Overweight (adjusted odds ratio 0.63, 95% CI 0.40-0.99) and obese I (adjusted odds ratio 0.44, 95% CI 0.28-0.72) were associated with decreased 30-day postoperative mortality compared with normal-weight counterparts. Such associations were prominent among younger (age younger than 65 y) patients but not older patients, and there was an interaction between age and overweight versus normal weight on mortality (P for interaction=0.04). CONCLUSIONS We found that among Chinese patients undergoing craniotomy for brain tumors, there was a J-shaped association between BMI and postoperative 30-day mortality, with lowest mortality at 27 kg/m². Moreover, in young patients, overweight and obese I were both associated with decreased risk of 30-day mortality.

Abstract
Background Postoperative prophylactic antibiotic usage for endoscopic skull base surgery varies based on the institution as evidence-based guidelines are lacking. The purpose of this study is to determine whether discontinuing postoperative prophylactic antibiotics in endoscopic endonasal cases led to a difference in central nervous system (CNS) infections, multi-drug resistant organism (MDRO) infections, or other postoperative infections. Methods This quality improvement study compared outcomes between a retrospective cohort (from September 2013 to March 2019) and a prospective cohort (April 2019 to June 2019) after adopting a protocol to discontinue prophylactic postoperative antibiotics in patients who underwent endoscopic endonasal approaches (EEAs). Our primary end points of the study included the presence of postoperative CNS infection, Clostridium difficile ( C. diff ), and MDRO infections. Results A total of 388 patients were analyzed, 313 in the pre-protocol group and 75 in the post-protocol group. There were similar rates of intraoperative cerebrospinal fluid leak (56.9 vs. 61.3%, p = 0.946). There was a statistically significant decrease in the proportion of patients receiving IV antibiotics during their postoperative course ( p = 0.001) and those discharged on antibiotics ( p = 0.001). There was no significant increase in the rate of CNS infections in the post-protocol group despite the discontinuation of postoperative antibiotics (3.5 vs. 2.7%, p = 0.714). There was no statistically significant difference in postoperative C. diff (0 vs. 0%, p = 0.488) or development of MDRO infections (0.3 vs 0%, p = 0.624). Conclusion Discontinuation of postoperative antibiotics after EEA at our institution did not change the frequency of CNS infections. It appears that discontinuation of antibiotics after EEA is safe.

Abstract
PURPOSE This study was performed to assess the effect of baseline Preoperative Laboratory Values (PLV) on post-operative Brain Tumor Resection (BTR) outcomes in a large national registry. METHODS We extracted data from the National Surgical Quality Improvement Program (NSQIP) database for BTR patients 2015-2019 (n = 3 0,951). Uni- and multivariate analyses were performed for PLV and key surgical outcomes. RESULTS The most significant PLV predictors of 30-day mortality after BTR included hypernatremia (odds ratio, OR 4.184, 95% CI, 2.384-7.343, p < 0.001), high serum creatinine (OR 2.244, 95% CI 1.502-3.352, p < 0.001), thrombocytopenia (OR 1.997, 95% CI 1.438, 2.772, p < 0.001), and leukocytosis (OR 1.635, 95% CI 1.264, 2.116, p < 0.001). The most significant predictors of Clavien IV complications were increased INR (OR 2.653, 95% CI 1.444, 4.875, p < 0.01), thrombocytopenia (OR 1.514, 95% CI 1.280, 1.792, p < 0.001), hypoalbuminemia (OR 1.480, 95% CI 1.274, 1.719, p < 0.001), and leukocytosis (OR 1.467, 95% CI 1.306, 1.647, p < 0.001). The most robust predictors of eLOS were increased INR (OR 1.941, 95% CI 1.231, 3.060, p < 0.01) and hypoalbuminemia (OR 1.993, 95% CI 1.823, 2.179, p < 0.001), and those for non-routine discharge included increased INR (OR 1.897, 95% CI 1.196, 3.008, p < 0.01) and hypernatremia (OR 1.565, 95% CI 1.217, 2.012, p < 0.001). CONCLUSIONS Several PLV independently predicted worse outcomes in BTR patients. Baseline labs should be routinely used for the pre-operative risk stratification of these patients.

The necessity for routine intensive care unit admission following elective craniotomy for epilepsy surgery: a retrospective single-center observational study. J Neurosurg 2022; 137:1203-1209.

Abstract
OBJECTIVE Traditionally, patients who underwent elective craniotomy for epilepsy surgery are monitored postoperatively in an intensive care unit (ICU) overnight in order to sufficiently respond to potential early postoperative complications. In the present study, the authors investigated the frequency of early postoperative events that entailed ICU monitoring in patients who had undergone elective craniotomy for epilepsy surgery. In a second step, they aimed at identifying pre- and intraoperative risk factors for the development of unfavorable events to distinguish those patients with the need for postoperative ICU monitoring at the earliest possible stage. METHODS The authors performed a retrospective observational cohort study assessing patients with medically intractable epilepsy (n = 266) who had undergone elective craniotomy for epilepsy surgery between 2012 and 2019 at a tertiary care epilepsy center, excluding those patients who had undergone invasive diagnostic approaches and functional hemispherectomy. Postoperative complications were defined as any unfavorable postoperative surgical and/or anesthesiological event that required further ICU therapy within 48 hours following surgery. A multivariate analysis was performed to reveal preoperatively identifiable risk factors for postoperative adverse events requiring an ICU setting. RESULTS Thirteen (4.9%) of 266 patients developed early postoperative adverse events that required further postoperative ICU care. The most prevalent event was a return to the operating room because of relevant postoperative intracranial hematoma (5 of 266 patients). Multivariate analysis revealed intraoperative blood loss ≥ 325 ml (OR 6.2, p = 0.012) and diabetes mellitus (OR 9.2, p = 0.029) as risk factors for unfavorable postoperative events requiring ICU therapy. CONCLUSIONS The present study revealed routinely collectable risk factors that would allow the identification of patients with an elevated risk of postsurgical complications requiring a postoperative ICU stay following epilepsy surgery. These findings may offer guidance for a stepdown unit admission policy following epilepsy surgical interventions after an external validation of the results.

Abstract
BACKGROUND Chronic subdural hematoma (cSDH) has a number of risk factors for recurrence, and some studies suggest obesity is one of them. Yet obesity has been shown to have a positive survival benefit in many diseases such as ischemic stroke, chronic obstructive pulmonary disease, percutaneous coronary intervention, and mechanical thrombectomy. Therefore, we sought to determine if obesity provided a mortality benefit in patients with cSDH undergoing burr hole drainage or craniotomy. METHODS We performed a retrospective database analysis using a multi-institutional (TriNetX) database looking at obese versus non-obese patients with cSDH undergoing surgical drainage. Our primary endpoint was mortality. Secondary endpoints included seizure, pulmonary embolism (PE), myocardial infarction (MI), cerebral infarction, deep vein thrombosis (DVT), tracheostomy, and percutaneous endoscopic gastrostomy (PEG). These were looked at to obtain a better idea of prognosis. Cohorts were propensity score-matched for confounders, using the greedy-nearest neighbor algorithm with a caliper of 0.1 pooled standard deviations. Kaplan-Meier survival curves were also developed, and hazard ratios were calculated. Chi-square analysis was performed on categorical variables. RESULTS A total of 1,849 patients were identified as obese with a drainage procedure, while 12,371 were identified as non-obese. Some 1,746 patients remained in each group after propensity score matching. Thirty-day survival rates were 88.08% in the obese vs. 83.82% in the non-obese cohorts, 90-day survival 85.15% vs. 79.35%, 365-day survival at 80.89% vs. 71.90%, and five-year survival at 64.75% vs. 54.84% (p < 0.0001). The risk difference was -8.02% (95% confidence interval, Cl -11.02, -5.021%); relative risk, RR 0.757, 95% Cl (0.67, 0.841); odds ratio, OR 0.676 (0.583, 0.783); p < 0.0001). Seizures, ventilator dependence, MI, cerebral infarction, tracheostomy, and PEG rates were all non-significant. Obese patients had a higher rate of PE (7.90% vs. 4.47%, p < 0.0001) and DVTs (12.37% vs. 10.02%, p = 0.0278). CONCLUSIONS Obesity in patients with cSDH undergoing surgical evacuation is associated with decreased mortality but higher rates of DVT and PE.

Abstract
Hypoalbuminemia is associated with poor outcome in patients undergoing surgery intervention. The main aim for this study was to investigate the incidence and the risk factors of postoperative hypoalbuminemia and assessed the impact of postoperative hypoalbuminemia on complications in patients undergoing brain tumor surgery. This retrospective study included 372 consecutive patients who underwent brain tumors surgery from January 2017 to December 2019. The patients were divided into hypoalbuminemia (< 35 g/L) and non-hypoalbuminemia group (≥ 35 g/L) based on postoperative albumin levels. Logistic regression analyses were used to determine risk factors. Of the total 372 patients, 333 (89.5%) developed hypoalbuminemia after surgery. Hypoalbuminemia was associated with operation time (OR 1.011, P < 0.001), preoperative albumin (OR 0.864, P = 0.015) and peroperative globulin (OR 1.192, P = 0.004). Postoperative pulmonary imaging abnormalities had a higher incidence in patients with than without hypoalbuminemia (41.1% vs 23.1%, P = 0.029). The independent predictors of postoperative pulmonary imaging abnormalities were age (OR 1.053, P < 0.001), operation time (OR 1.003, P = 0.013) and lower postoperative albumin (OR 0.946, P = 0.018). Pulmonary imaging abnormalities [OR 19.862 (95% CI 2.546–154.936, P = 0.004)] was a novel independent predictors of postoperative pneumonia. Postoperative hypoalbuminemia has a higher incidence with the increase of operation time, and may be associated with postoperative complications in patients undergoing brain tumor surgery.

Abstract
OBJECTIVE Sarcopenia is an important prognostic consideration in surgical oncology that has received relatively little attention in brain tumor patients. Temporal muscle thickness (TMT) has recently been proposed as a novel radiographic marker of sarcopenia that can be efficiently obtained within existing workflows. We investigated the prognostic value of TMT in primary and progressive glioblastoma. METHODS TMT measurements were performed on magnetic resonance images of 384 patients undergoing 541 surgeries for glioblastoma. Relationships between TMT and clinical characteristics were examined on bivariate analysis. Optimal TMT cutpoints were established using maximally selected rank statistics. Predictive value of TMT upon postoperative survival (PS) was assessed using Cox proportional hazards regression adjusted for age, sex, Karnofsky performance status (KPS), Stupp protocol completion, extent of resection, and tumor molecular markers. RESULTS Average TMT for the primary and progressive glioblastoma cohorts was 9.55 mm and 9.40 mm, respectively. TMT was associated with age (r = -0.14, p = 0.0008), BMI (r = 0.29, p < 0.0001), albumin (r = 0.11, p = 0.0239), and KPS (r = 0.11, p = 0.0101). Optimal TMT cutpoints for the primary and progressive cohorts were ≤ 7.15 mm and ≤ 7.10 mm, respectively. High TMT was associated with increased Stupp protocol completion (p = 0.001). On Cox proportional hazards regression, high TMT predicted increased PS in progressive [HR 0.47 (95% confidence interval (CI)) 0.25-0.90), p = 0.023] but not primary [HR 0.99 (95% CI 0.64-1.51), p = 0.949] glioblastoma. CONCLUSIONS TMT correlates with important prognostic variables in glioblastoma and predicts PS in patients with progressive, but not primary, disease. TMT may represent a pragmatic neurosurgical biomarker in glioblastoma that could inform treatment planning and perioperative optimization.

Abstract
OBJECTIVES Several factors are commonly associated with the occurrence of post-operative infection after craniotomy. However, the risk factors associated with tumor surgery have been less intensively investigated. The aim of the present study was to analyze the risk factors for infection and categorize patients according to risk rate. METHODS In this study, we retrospectively evaluated 987 adult patients consecutively submitted to craniotomy for tumor resection. The primary outcome was the occurrence of infection within 30 days after surgery. The following independent variables were assessed: age, gender, surgery duration, length of hospital stay prior to surgery, reoperation, body mass index, serum albumin, hemoglobin, lactic dehydrogenase, smoking, diabetes, corticoid use, preoperative chemotherapy, previous irradiation, elective or urgent indication for surgery, supra or infratentorial lesion location, and tumor histology. We performed a recursive partitioning analysis to assess the relative importance of these variables in predicting infection. RESULTS The model returned a 3-level classification: 1. CSF-leakage (relative contribution 70%), 2. Emergency surgery indication (18%), and 3. Tumor histology (8%). Additionally, partitioning clustered together 3 risk groups: 1. CSF-leakage group (probability of infection 72.5%), 2. No CSF-leakage and urgent surgery (mean probability 18.1%); and 3. no CSF-leakage and no urgent surgery (3.4%). The misclassification rate was 4.5%, the overall specificity and sensitivity were 99.6% and 75.5%, respectively, and the area under the ROC-curve was 0.6908. CONCLUSION Our analysis indicates that technical and treatment-related factors are significantly more relevant than patient- or disease-related factors in determining the risk of postoperative infection.

Garcia CM, Pertsch NJ, Leary OP, Rivera Perla KM, Tang O, Toms SA, Weil RJ. Early outcomes of supratentorial cranial surgery for tumor resection in older patients. J Clin Neurosci 2020; 83:88-95. [PMID: 33342625 DOI: 10.1016/j.jocn.2020.11.022] [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: 07/26/2020] [Revised: 09/15/2020] [Accepted: 11/23/2020] [Indexed: 01/12/2023]
Abstract
With longevity increasing in the United States, more older individuals are presenting with supratentorial brain tumors. Despite improved perioperative management, there is persistent disparity in surgical resection rates among patients aged 65 years or older. We aim to assess the effects of advanced age (≥65 years) on 30-day outcomes in patients with supratentorial tumors who underwent craniotomy for supratentorial tumor resection. Data obtained in adults who underwent supratentorial tumor resections was extracted from the prospectively-collected American College of Surgeons: National Surgical Quality Improvement Program (NSQIP; 2012-2018) database. Using multivariate regression, we compared odds of major and minor complications; prolonged length-of-stay (LOS); discharge anywhere other than home; and 30-day readmission, reoperation, and mortality rates between patients aged 18-64 years (the control cohort) and those 65-74 years or ≥75 years of age. Of the 14,234 patients who underwent craniotomy for supratentorial tumors and met inclusion criteria, 30.7% were ≥65 years of age; 71.4% of these were 65-74 years and 28.6% were ≥75 years old. Compared to the control group, both older subpopulations had more medical comorbidities. Both older subgroups had increased odds of major complications and prolonged LOS relative to the control group. Older patients had greater odds of mortality at 30 days. Advanced age, defined as ≥65 years, was significantly associated with higher odds of complications, prolonged LOS, and mortality within the 30-day post- operative period after adjusting for potential confounders. Age is one important consideration when prospectively risk-stratifying patients to minimize and mitigate suboptimal perioperative outcomes.

Abstract
BACKGROUND Multiple nationwide outcome registries are utilized for quality benchmarking between institutions and individual surgeons. OBJECTIVE To evaluate whether nationwide quality of care programs in the United Kingdom and United States can measure differences in neurosurgical quality. METHODS This prospective observational study comprised 418 consecutive adult patients undergoing elective craniotomy at Helsinki University Hospital between December 7, 2011 and December 31, 2012.We recorded outcome event rates and categorized them according to British Neurosurgical National Audit Programme (NNAP), American National Surgical Quality Improvement Program (NSQIP), and American National Neurosurgery Quality and Outcomes Database (N2QOD) to assess the applicability of these programs for quality benchmarking and estimated sample sizes required for reliable quality comparisons. RESULTS The rate of in-hospital major and minor morbidity was 18.7% and 38.0%, respectively, and 30-d mortality rate was 2.4%. The NSQIP criteria identified 96.2% of major but only 38.4% of minor complications. N2QOD performed better, but almost one-fourth (23.2%) of all patients with adverse outcomes, mostly minor, went unnoticed. For NNAP, a sample size of over 4200 patients per surgeon is required to detect a 50.0% increase in mortality rates between surgeons. The sample size required for reliable comparisons between the rates of complications exceeds 600 patients per center per year. CONCLUSION The implemented benchmarking programs in the United Kingdom and United States fail to identify a considerable number of complications in a high-volume center. Health care policy makers should be cautious as outcome comparisons between most centers and individual surgeons are questionable if based on the programs.

Abstract
We aimed to investigate the correlations between biochemical and hematological markers and the clinical conditions of brain tumor patients before and after craniotomy. A retrospective study was conducted in 90 brain tumor patients. Age, gender, underlying diseases, tumor size and intraoperative blood loss were recorded. Red blood cell counts and hepatic and renal markers were analyzed preoperatively and postoperatively. Albumin decreased by 5.6 g/L after surgery (p < 0.001). Older patients (>52 years) and females had lower albumin levels than younger patients and males did. Red blood cell counts and hemoglobin levels decreased significantly on the 1st and increased on the 3rd postoperative day. The blood glucose level increased on the 1st postoperative day and then decreased. Older patients had higher blood glucose levels than younger patients did (p < 0.05). The postoperative serum sodium, potassium and calcium levels were within the normal ranges; 37 patients had hypocalcemia (41.1%) and patients with hypokalemia and hyponatremia increased postoperatively. Albumin and hemoglobin levels were linearly correlated (correlation coefficient 0.559, p < 0.001). Intraoperative blood loss was correlated with tumor size (p < 0.05) but did not affect the decrease in hematological markers. In brain tumor patients, red blood cell counts and hemoglobin and serum albumin levels were significantly decreased after craniotomy; these effects were influenced by gender and age instead of intraoperative blood loss. The postoperative blood glucose level peaked and then decreased; it was affected by age and diabetes mellitus. Electrolytes remained relatively stable. These findings have implications for patient management and postoperative complication prevention.

Abstract
AbstractBACKGROUNDUse of large databases such as the American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) has become increasingly common in neurosurgical research.OBJECTIVETo perform a critical appraisal and evaluation of the methodological reporting for studies in neurosurgical literature that utilize the ACS-NSQIP database.METHODSWe queried Ovid MEDLINE, EMBASE, and PubMed databases for all neurosurgical studies utilizing the ACS-NSQIP. We assessed each study according to number of criteria fulfilled with respect to Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) Statement, REporting of studies Conducted using Observational Routinely-collected Health Data (RECORD) Statement, and Journal of American Medical Association–Surgical Section (JAMA-Surgery) Checklist. A separate analysis was conducted among papers published in core and noncore journals in neurosurgery according to Bradford's law.RESULTSA total of 117 studies were included. Median (interquartile range [IQR]) scores for number of fulfilled criteria for STROBE Statement, RECORD Statement, and JAMA-Surgery Checklist were 20 (IQR:19-21), 9 (IQR:8-9), and 6 (IQR:5-6), respectively. For STROBE Statement, RECORD Statement, and JAMA-Surgery Checklist, item 9 (potential sources of bias), item 13 (supplemental information), and item 9 (missing data/sensitivity analysis) had the highest number of studies with no fulfillment among all studies (56, 68, 50%), respectively. When comparing core journals vs noncore journals, no significant difference was found (STROBE, P = .94; RECORD, P = .24; JAMA-Surgery checklist, P = .60).CONCLUSIONWhile we observed an overall satisfactory reporting of methodology, most studies lacked mention of potential sources of bias, data cleaning methods, supplemental information, and external validity. Given the pervasive role of national databases and registries for research and health care policy, the surgical community needs to ensure the credibility and quality of such studies that ultimately aim to improve the value of surgical care delivery to patients.

Abstract
Background Thirty-day readmission has become a significant health care metric reflecting the quality of care and on the cost of service delivery. There is little data on the impact of complications following skull base surgery (SBS) on emergency readmission. Identifying modifiable risk factors for readmission may improve care and reduce cost. Design The study was designed as a single-center retrospective cohort study. Methods Records for a consecutive series of 165 patients who underwent open or endoscopic SBS by a single surgeon reviewed. Patients with pituitary adenoma were excluded. The diagnosis, procedure, complications, length of stay (LOS), body mass index (BMI), and smoking status were recorded. Readmission to the neurosurgical department or regional hospitals was either noted prospectively or the patient contacted. Cause and length of readmission was documented. Results Of the 165 cases, 14 (8.5%) were readmitted within 30 days. Causes for readmission included cerebrospinal fluid (CSF) leak in 5/14 or 35.7% (overall rate for readmission for this complication in the series is 3.1%), infection in 4/14 (28.6%), hyponatraemia in 2/14 (14.3%), vascular: sinus thrombosis in 1/14 (7.1%), seizures in 1/14 (7.1%), and epistaxis in 1/14 (7.1%). Initial and readmission LOS was 6 and 14 days, respectively. BMI was higher in those readmitted within 30 days (33.2 kg/m 2 ) versus no readmission (27.1 kg/m 2 ). In addition, of those readmitted within 30 days, 35.7% were smokers compared with 20.8% in those not readmitted. Conclusion In this series, smoking and raised BMI may be indicators for within 30-day readmission and complications in this population, raising the question of risk factor modification prior to elective intervention.

GLP1 Receptor Agonist Liraglutide Is an Effective Therapeutic Option for Perioperative Glycemic Control in Type 2 Diabetes within Enhanced Recovery After Surgery (ERAS) Protocols. Eur Surg Res 2018; 59:349-360. [PMID: 30537714 DOI: 10.1159/000494768] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2018] [Accepted: 10/23/2018] [Indexed: 11/19/2022]
Abstract
BACKGROUND Enhanced Recovery After Surgery (ERAS) protocols are multimodal perioperative care pathways designed to achieve early recovery after surgical procedures by maintaining preoperative organ function and reducing profound stress responses following surgery [Wilmore and Kehlet: BMJ 2001; 322(7284): 473-6]. Glucagon-like peptide-1 receptor agonists (GLP-1RAgs), such as liraglutide, have recently been widely used as antidiabetic agents in patients with type 2 diabetes (T2D) because they maintain blood glucose at an ideal level throughout the day, including during postprandial periods, thereby improving hypoglycemia and body weight more than insulin therapies. Additionally, the administration of liraglutide may exert cardiovascular, renal, and cerebral protective effects in T2D patients. The use of GLP-1RAgs for perioperative glycemic control is sometimes considered to be controversial. METHODS The efficacy and safety of liraglutide therapy during perioperative glycemic control in elective surgery patients within ERAS protocols were compared with those of insulin therapy. Ninety adult T2D patients scheduled to undergo elective surgery within ERAS protocols were randomized and analyzed. Forty-nine subjects were prescribed liraglutide and 41 insulin therapy. Procedures comprised orthopedic, thoracic, urological, otolaryngological, hepatic resection, and gynecological breast surgeries. RESULTS Liraglutide was shown to be a more effective option than insulin therapy because (1) glycemic levels were more stable; (2) the number of patients requiring additional insulin according to the insulin sliding scale was significantly smaller (Fisher's exact test, p = 0.005); (3) the insulin dosage required on the day of surgery was significantly smaller (Fisher's exact, p = 0.004); (4) the additional insulin volume required was significantly less for patients throughout the perioperative period (Fisher's exact test, p = 0.001); and (5) while lean body mass remained the same, body fat measurements, particularly visceral fat, tended to decrease. CONCLUSIONS Based on the results of the present study and a recent large-scale clinical study showing cardiovascular and renal protective effects in T2D patients, we consider the administration of liraglutide within ERAS protocols for T2D patients to represent a more comprehensive suite of patient protection measures as a perioperative non-insulin agent, particularly in patients with limited exercise ability and those at risk of hypoglycemia.

Abstract
BACKGROUND Reoperation has been increasingly utilized as a metric evaluating quality of care. OBJECTIVE To evaluate the rate of, reasons for, and predictors of unplanned reoperation after craniotomy for tumor in a nationally accrued population. METHODS Patients who underwent cranial tumor resection were extracted from the prospective National Surgical Quality Improvement Program registry (2012-2014). Multivariate logistic regression examined predictors of unplanned cranial reoperation. Predictors screened included patient age, sex, tumor location and histology, functional status, comorbidities, preoperative laboratory values, operative urgency, and time. RESULTS Of the 11 462 patients included, 3.1% (n = 350) underwent an unplanned cranial reoperation. The most common reasons for cranial reoperation were intracranial hematoma evacuation (22.5%), superficial or intracranial surgical site infections (11.9%), re-resection of tumor (8.4%), decompressive craniectomy (6.1%), and repair of cerebrospinal fluid leakage (5.6%). The strongest predictor of any cranial reoperation was preoperative thrombocytopenia (less than 100 000/μL, odds ratio [OR] = 2.51, 95% confidence interval [CI]: 1.23-5.10, P = .01). Thrombocytopenia, hypertension, emergent surgery, and longer operative time were predictors of reoperation for hematoma (P ≤ .004), while dependent functional status, morbid obesity, leukocytosis, and longer operative time were predictors of reoperation for infection (P < .05). Although any unplanned cranial reoperation was not associated with differential odds of mortality (OR = 1.68, 95% CI: 0.94-3.00, P = .08), hematoma evacuation was significantly associated with thirty-day death (P = .04). CONCLUSION In this national analysis, unplanned cranial reoperation was primarily associated with operative indices, rather than preoperative characteristics, suggesting that reoperation may have some utility as a quality indicator. However, hypertension and thrombocytopenia were potentially modifiable predictors of reoperation.

Abstract
Venous thromboembolism (VTE), including deep venous thrombosis (DVT) and pulmonary embolism (PE), frequently complicates the postoperative course of primary malignant brain tumor patients. Thromboprophylactic anticoagulation is commonly used to prevent VTE at the risk of intracranial hemorrhage (ICH). We extracted all patients who underwent craniotomy for a primary malignant brain tumor from the National Surgical Quality Improvement Program (NSQIP) registry (2005-2015) to perform a time-to-event analysis and identify relevant predictors of DVT, PE, and ICH within 30 days after surgery. Among the 7376 identified patients, the complication rates were 2.6, 1.5, and 1.3% for DVT, PE, and ICH, respectively. VTE was the second-most common major complication and third-most common reason for readmission. ICH was the most common reason for reoperation. The increased risk of VTE extends beyond the period of hospitalization, especially for PE, whereas ICH occurred predominantly within the first days after surgery. Older age and higher BMI were overall predictors of VTE. Dependent functional status and longer operative times were predictive for VTE during hospitalization, but not for post-discharge events. Admission two or more days before surgery was predictive for DVT, but not for PE. Preoperative steroid usage and male gender were predictive for post-discharge DVT and PE, respectively. ICH was associated with various comorbidities and longer operative times. This multicenter study demonstrates distinct critical time periods for the development of thrombotic and hemorrhagic events after craniotomy. Furthermore, the VTE risk profile depends on the type of VTE (DVT vs. PE) and clinical setting (hospitalized vs. post-discharge patients).
