Abstract
We aimed to determine the impact of pre-operative isolation on postoperative pulmonary complications after elective surgery during the global SARS-CoV-2 pandemic. We performed an international prospective cohort study including patients undergoing elective surgery in October 2020. Isolation was defined as the period before surgery during which patients did not leave their house or receive visitors from outside their household. The primary outcome was postoperative pulmonary complications, adjusted in multivariable models for measured confounders. Pre-defined sub-group analyses were performed for the primary outcome. A total of 96,454 patients from 114 countries were included and overall, 26,948 (27.9%) patients isolated before surgery. Postoperative pulmonary complications were recorded in 1947 (2.0%) patients of which 227 (11.7%) were associated with SARS-CoV-2 infection. Patients who isolated pre-operatively were older, had more respiratory comorbidities and were more commonly from areas of high SARS-CoV-2 incidence and high-income countries. Although the overall rates of postoperative pulmonary complications were similar in those that isolated and those that did not (2.1% vs 2.0%, respectively), isolation was associated with higher rates of postoperative pulmonary complications after adjustment (adjusted OR 1.20, 95%CI 1.05-1.36, p = 0.005). Sensitivity analyses revealed no further differences when patients were categorised by: pre-operative testing; use of COVID-19-free pathways; or community SARS-CoV-2 prevalence. The rate of postoperative pulmonary complications increased with periods of isolation longer than 3 days, with an OR (95%CI) at 4-7 days or ≥ 8 days of 1.25 (1.04-1.48), p = 0.015 and 1.31 (1.11-1.55), p = 0.001, respectively. Isolation before elective surgery might be associated with a small but clinically important increased risk of postoperative pulmonary complications. Longer periods of isolation showed no reduction in the risk of postoperative pulmonary complications. These findings have significant implications for global provision of elective surgical care.

Preoperative lymphopaenia, mortality, and morbidity after elective surgery: systematic review and meta-analysis. Br J Anaesth 2021; 127:32-40. [PMID: 33795133 PMCID: PMC8258977 DOI: 10.1016/j.bja.2021.02.023] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2020] [Revised: 01/16/2021] [Accepted: 02/01/2021] [Indexed: 12/17/2022] Open
Abstract
BACKGROUND In the general adult population, lymphopaenia is associated with an increased risk for hospitalisation with infection and infection-related death. The quality of evidence and strength of association between perioperative lymphopaenia across different surgical procedures and mortality/morbidity has not been examined by systematic review or meta-analysis. METHODS We searched MEDLINE, Embase, Web of Science, Google Scholar, and Cochrane databases from their inception to June 29, 2020 for observational studies reporting lymphocyte count and in-hospital mortality rate in adults. We defined preoperative lymphopaenia as a lymphocyte count 1.0-1.5×109 L-1. Meta-analysis was performed using either fixed or random effects models. Quality was assessed using the Newcastle-Ottawa Scale. The I2 index was used to quantify heterogeneity. The primary outcome was in-hospital mortality rate and mortality rate at 30 days. RESULTS Eight studies met the inclusion criteria for meta-analysis, comprising 4811 patients (age range, 46-91 yr; female, 20-79%). These studies examined preoperative lymphocyte count exclusively. Studies were of moderate to high quality overall, ranking >7 using the Newcastle-Ottawa Scale. Preoperative lymphopaenia was associated with a threefold increase in mortality rate (risk ratio [RR]=3.22; 95% confidence interval [CI], 2.19-4.72; P<0.01, I2=0%) and more frequent major postoperative complications (RR=1.33; 95% CI, 1.21-1.45; P<0.01, I2=6%), including cardiovascular morbidity (RR=1.77; 95% CI, 1.45-2.15; P<0.01, I2=0%), infections (RR=1.45; 95% CI, 1.19-1.76; P<0.01, I2=0%), and acute renal dysfunction (RR=2.66; 95% CI, 1.49-4.77; P<0.01, I2=1%). CONCLUSION Preoperative lymphopaenia is associated with death and complications more frequently, independent of the type of surgery. PROSPERO REGISTRY NUMBER CRD42020190702.

Abstract
IMPORTANCE Low-value care, defined as care offering no net benefit in specific clinical scenarios, is associated with harmful outcomes in patients and wasteful spending. Despite a national education campaign and increasing attention on reducing health care waste, recent trends in low-value care delivery remain unknown. OBJECTIVE To assess national trends in low-value care use and spending. DESIGN, SETTING, AND PARTICIPANTS In this cross-sectional study, analyses of low-value care use and spending from 2014 to 2018 were conducted using 100% Medicare fee-for-service enrollment and claims data. Included individuals were aged 65 years or older and continuously enrolled in Medicare parts A, B, and D during each measurement year and the previous year. Data were analyzed from September 2019 through December 2020. EXPOSURE Being enrolled in fee-for-service Medicare for a period of time, in years. MAIN OUTCOMES AND MEASURES The Milliman MedInsight Health Waste Calculator was used to assess 32 claims-based measures of low-value care associated with Choosing Wisely recommendations and other professional guidelines. The calculator designates services as wasteful, likely wasteful, or not wasteful based on an absence of indication of appropriate use in the claims history; calculator-designated wasteful services were defined as low-value care. Spending was calculated as claim-line level (ie, spending on the low-value service) and claim level (ie, spending on the low-value service plus associated services), adjusting for inflation. RESULTS Among 21 045 759 individuals with fee-for-service Medicare (mean [SD] age, 77.4 [7.9] years; 12 515 915 [59.5%] women), the percentage receiving any of 32 low-value services decreased from 36.3% (95% CI, 36.3%-36.4%) to 33.6% (95% CI, 33.6%-33.6%) from 2014 to 2018. Uses of low-value services per 1000 individuals decreased from 677.8 (95% CI, 676.2-679.5) to 632.7 (95% CI, 632.6-632.8) from 2014 to 2018. Three services comprised approximately two-thirds of uses among 32 low-value services per 1000 individuals: preoperative laboratory testing decreased from 213.8 (95% CI, 213.4-214.2) to 166.2 (95% CI, 166.2-166.2), while opioids for back pain increased from 154.4 (95% CI, 153.6-155.2) to 182.1 (95% CI, 182.1-182.1) and antibiotics for upper respiratory infections increased from 75.0 (95% CI, 75.0-75.1) to 82 (95% CI, 82.0-82.0). Spending per 1000 individuals on low-value care also decreased, from $52 765.5 (95% CI, $51 952.3-$53 578.6) to $46 921.7 (95% CI, $46 593.7-$47 249.7) at the claim-line level and from $160 070.4 (95% CI, $158 999.8-$161 141.0) to $144 741.1 (95% CI, $144 287.5-$145 194.7) at the claim level. CONCLUSIONS AND RELEVANCE This cross-sectional study found that among individuals with fee-for-service Medicare receiving any of 32 measured services, low-value care use and spending decreased marginally from 2014 to 2018, despite a national education campaign in collaboration with clinician specialty societies and increased attention on low-value care. While most use of low-value care came from 3 services, 1 of these was opioid prescriptions, which increased over time despite the harms associated with their use. These findings may represent several opportunities to prevent patient harm and lower spending.

Abstract
STUDY DESIGN Retrospective review. OBJECTIVE The aim of this study was to examine the association between preoperative depression and patient satisfaction in the outpatient spine clinic after lumbar surgery. SUMMARY OF BACKGROUND DATA The Clinician and Group Assessment of Healthcare Providers and Systems (CG-CAHPS) survey is used to measure patient experience in the outpatient setting. CG-CAHPS scores may be used by health systems in physician incentive programs and quality improvement initiatives or by prospective patients when selecting spine surgeons. Although preoperative depression has been shown to predict poor patient-reported outcomes and less satisfaction with the inpatient experience following lumbar surgery, its impact on patient experience with spine surgeons in the outpatient setting remains unclear. METHODS Patients who underwent lumbar surgery and completed the CG-CAHPS survey at postoperative follow-up with their spine surgeon between 2009 and 2017 were included. Data were collected on patient demographics, Patient Health Questionnaire 9 (PHQ-9) scores, and Patient-Reported Outcome Measurement Information System Global Health Physical Health (PROMIS-GPH) subscores. Patients with preoperative PHQ-9 scores ≥10 (moderate-to-severe depression) were included in the depressed cohort. The association between preoperative depression and top-box satisfaction ratings on several dimensions of the CG-CAHPS survey was examined. RESULTS Of the 419 patients included in this study, 72 met criteria for preoperative depression. Depressed patients were less likely to provide top-box satisfaction ratings on CG-CAHPS metrics pertaining to physician communication and overall provider rating (OPR). Even after controlling for patient-level covariates, our multivariate analysis revealed that depressed patients had lower odds of reporting top-box OPR (odds ratio [OR]: 0.19, 95% confidence interval [CI]: 0.06-0.63, P = 0.007), feeling that their spine surgeon provided understandable explanations (OR: 0.32, 95% CI: 0.11-0.91, P = 0.032), and feeling that their spine surgeon provided understandable responses to their questions or concerns (OR: 0.19, 95% CI: 0.06-0.63, P = 0.007). CONCLUSION Preoperative depression is independently associated with lower OPR and satisfaction with spine surgeon communication in the outpatient setting after lumbar surgery.Level of Evidence: 3.

Abstract
STUDY DESIGN This is a retrospective cohort study. OBJECTIVE To evaluate the long-term outcomes after surgery for refractory coccygodynia in patients with normal imaging studies compared with patients where imaging shows an anomaly. SUMMARY OF BACKGROUND DATA Patients with coccydynia who do not respond to conservative treatment will often profit from coccygectomy. Most surgeons employ plain radiographs or magnetic resonance imaging (MRI) in their preoperative work-up. These will often show anomalies, but in some cases they do not. We investigated whether these patients do less well than those with abnormal images. METHODS We operated on 184 patients with coccydynia during a 7-year period and 171 (93%) responded to follow-up questionnaires after 37 (range: 12-85) months. Images of 33 patients were normal and 138 showed some coccygeal pathology. Surgery was considered to have been unsuccessful when respondents stated at review that they were somewhat better, unchanged, or worse. RESULTS There were no clinically or statistically significant differences in outcome between the groups. Surgery was unsuccessful in 24% of patients with normal images and in 32% among those with abnormal images. The median pain scores (0-10) during the week before review were two (interquartile range [IQR]: 0-3) and one (IQR: 1-5) in the two groups respectively. Similar proportions in the two groups stated that they would not have consented to surgery if they had known the outcome in advance. CONCLUSION Patients with severe coccydynia who have not responded to conservative treatment should not be denied surgery only because their radiographs or MRI studies look normal. LEVEL OF EVIDENCE 4.

Abstract
Frailty has been associated with increased morbidity and mortality in a variety of surgical disciplines. Few data exist regarding the relationship of frailty with adverse outcomes in craniotomy for brain tumor resection. We assessed the relationship between frailty and the incidence of major post-operative complication, discharge destination other than home, 30-day readmission, and 30-day mortality after elective craniotomy for brain tumor resection. A retrospective cohort study was conducted on 20,333 adult patients undergoing elective craniotomy for tumor resection in the 2012-2018 ACS-NSQIP Participant Use File. Multivariate logistic regression was performed using all covariates deemed eligible through clinical and statistical significance. 6,249 patients (30.7%) were low-frailty and 2,148 patients (10.6%) were medium-to-high frailty. In multivariate logistic regression adjusting for age, gender, BMI, ASA classification, smoking status, dyspnea, significant pre-operative weight loss, chronic steroid use, bleeding disorder, tumor type, and operative time, low frailty was associated with increased adjusted odds ratio of major complication (1.41, 95% CI: 1.23-1.60, p < 0.001), discharge destination other than home (1.32, 95% CI: 1.20-1.46, p < 0.001), 30-day readmission (1.29, 95% CI: 1.15-1.44, p < 0.001), and 30-day mortality (1.87, 95% CI: 1.41-2.47, p < 0.001). Moderate-to-high frailty was also associated with increased adjusted odds of major complication (1.61, 95% CI: 1.35-1.92, p < 0.001), discharge destination other than home (1.80, 95% CI: 1.58-2.05), 30-day readmission (1.39, 95% CI: 1.19-1.62, p < 0.001), and 30-day mortality (2.42, 95% CI: 1.74-3.38, p < 0.001). CONCLUSIONS: Frailty is associated with increased odds of major post-operative complication, discharge to destination other than home, 30-day readmission, and 30-day mortality.

Effect of change in preoperative depression/anxiety on patient outcomes following lumbar spine surgery. Clin Neurol Neurosurg 2020; 199:106312. [PMID: 33069091 DOI: 10.1016/j.clineuro.2020.106312] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2020] [Revised: 10/10/2020] [Accepted: 10/12/2020] [Indexed: 12/31/2022]
Abstract
OBJECTIVE The purpose of this study was to investigate the association between positive change in depression or anxiety within three months post-operation and clinically meaningful changes in long-term clinical outcomes after lumbar spine surgery. METHODS This study included adults with preoperative diagnosis of depression or anxiety who underwent lumbar spine surgery in the Quality Outcomes Database (QOD) from 2012 to 2018 with either a 12- or 24-month follow-up. Positive change in depression and anxiety was assessed three months after surgery. Clinical outcomes measured included Numeric Rating Scale (NRS) score for back pain (BP) and leg pain (LP), Oswestry Disability Index score (ODI) for disability, EuroQol Visual Analog Scale score (EQ-VAS) for health-related quality of life (HRQOL), and North American Spine Surgery (NASS) index score for patient satiaction measured at 12- and 24 months after surgery. RESULTS Of the 9,656 and 1,393 patients who were included in the 12- and 24-month cohort, respectively, 7,277 patients (75.4 %) and 1,089 (78.2 %) experienced a positive change in depression or anxiety within three months after surgery. At both 12- and 24-month follow-up, patients who had positive change in depression or anxiety were more likely to achieve minimal clinically important changes in NRS-BP/LP, ODI, EQ-VAS, and NASS (all p < 0.01) compared to those who did not experience improvement in depression or anxiety. CONCLUSION Depression and anxiety are important comorbidities to consider in patients undergoing lumbar spine surgery. Positive change in depression and anxiety are associated with improvements in pain, disability, satisfaction, and overall functioning.

Abstract
Stone disease is a unique condition that requires appropriate management in a timely manner as it can result in both emergent conditions and long term effects on kidney functions. In this study it is aimed to identify the up-to-date practice patterns related to preoperative evaluation and anesthesia for stone disease interventions during COVID-19 pandemic. The data of 473 patients from 11 centers in 5 different countries underwent interventions for urinary stones during the Covid-19 pandemic was collected and analyzed retrospectively. Information on the type of the stone related conditions, management strategies, anesthesiologic evaluation, anesthesia methods, and any alterations related to COVID-19 pandemic was collected. During the preoperative anesthesia evaluation thorax CT was performed in 268 (56.7%) and PCR from nasopharyngeal swab was performed in 31 (6.6%) patients. General anesthesia was applied in 337 (71.2%) patients and alteration in the method of anesthesia was recorded in 45 (9.5%) patients. A cut-off value of 21 days was detected for the hospitals to adapt changes related to COVID-19. Rate of preoperative testing, emergency procedures, conservative approaches and topical/regional anesthesia increased after 21 days. The preoperative evaluation for management of urinary stone disease is significantly affected by COVID-19 pandemic. There is significant alteration in anesthesia methods and interventions. The optimal methods for preoperative evaluation are still unknown and there is discordance between different centers. It takes 21 days for hospitals and surgeons to adapt and develop new strategies for preoperative evaluation and management of stones.

Abstract
The standard treatment for locally advanced gastric cancer differs across the world. In western countries, perioperative chemotherapy or postoperative adjuvant chemoradiotherapy are the preferred treatment options, whereas in Asia, D2 gastrectomy followed by postoperative adjuvant chemotherapy is standard. In Japan, adjuvant chemotherapy with S-1 is the standard treatment for pStage II gastric cancer, whereas adjuvant chemotherapy with a doublet regimen is preferred for pStage III gastric cancer. The efficacy of preoperative neoadjuvant chemotherapy using S-1 plus cisplatin, has been investigated in selected patients with expected poor survival outcomes. To expand the indications for neoadjuvant chemotherapy, a clinical trial investigating the efficacy of preoperative S-1 plus oxaliplatin in patients with cStage III (cT3-4N1-3) gastric cancer (JCOG1509) is ongoing in Japan. The addition of immune checkpoint inhibitors to cytotoxic chemotherapy also seems promising and is being investigated in international randomized clinical trials. Although we have to await the final results of these studies, preoperative neoadjuvant chemotherapy is a promising treatment strategy and likely to become standard treatment for locally advanced gastric cancer in Japan.

Abstract
AIMS We studied the purchases of medical therapy recommended for coronary artery disease patients before and after elective revascularisation (percutaneous coronary intervention (PCI) or coronary bypass grafting (CABG)). METHODS All patients who underwent an elective PCI (N = 1557) or CABG (N = 1768) at the Heart Center, Kuopio University hospital between 2007 and 2014 were included. Data were collected from the hospital's coronary register and national registers, and obtained for 3 years before and 1 year after the revascularisation. RESULTS Altogether 85.2% of PCI patients and 88.1% of CABG patients had purchased lipid-modifying agents before the procedure, and 94.9% and 96.8% during the post-procedure follow-up year, respectively. Beta-blocking agents were purchased by 84.9% of PCI patients before and by 87.9% after the procedure and by 86.3% of CABG patients before and 97.1% after the operation. Of PCI patients, 64.3% had purchased organic long-acting nitrates before the procedure and 54.4% also after the procedure. Among CABG patients, the purchase of organic long-acting nitrates fell from 59.7% before to 10.1% after the operation. The use of ADP receptor blocking agents increased in PCI patients (26.3 to 83.9%) and the use of warfarin in CABG patients (9.4 to 21.3%). Medication purchases were more common among those who had greater use of hospital services before and after the procedures. CONCLUSIONS In both PCI and CABG patients, the use of medical therapy before and after revascularisation procedure complied with current guidelines. Purchases of long-acting nitrates were common in the PCI group even after the procedure.

Abstract
BACKGROUND The American Society of Anesthesiologists (ASA) Choosing Wisely Top-5 list of activities to avoid includes "Don't obtain baseline laboratory studies in patients without significant systemic disease (ASA I or II) undergoing low-risk surgery - specifically complete blood count, basic or comprehensive metabolic panel, coagulation studies when blood loss (or fluid shifts) is/are expected to be minimal." Accordingly, we define low-value preoperative tests (LVTs) as those performed before minor surgery in patients without significant systemic disease. The objective of the current study was to examine the extent, variability, drivers, and costs of LVTs before carpal tunnel release (CTR) surgeries in the US Veterans Health Administration (VHA). METHODS Using fiscal year (FY) 2015-2017 data derived from the VHA Corporate Data Warehouse (CDW), we determined the overall national and facility-level rates and associated costs of receiving any of 8 common LVTs in the 30 days before CTR in ASA physical status (PS) I-II patients. We also examined the patient, procedure, and facility factors associated with receiving ≥1 LVT with mixed-effects logistic regression and the number of tests received with mixed-effects negative binomial regression. RESULTS From FY15-17, 10,000 ASA class I-II patients received a CTR by 699 surgeons in 125 VHA facilities. Overall, 47.0% of patients had a CTR that was preceded by ≥1 LVT, with substantial variability between facilities (range = 0%-100%; interquartile range = 36.3%), representing $339,717 in costs. Older age and female sex were associated with higher odds of receiving ≥1 LVT. Local versus other modes of anesthesia were associated with lower odds of receiving ≥1 LVT. Several facilities experienced large (>25%) increases or decreases from FY15 to FY17 in the proportion of patients receiving ≥1 LVT. CONCLUSIONS Counter to guidance from the ASA, we found that almost half of CTRs performed on ASA class I-II VHA patients were preceded by ≥1 LVT. Although the total cost of these tests is relatively modest, CTR is just one of many low-risk procedures (eg, trigger finger release, cataract surgery) that may involve similar preoperative testing practices. These results will inform site selection for qualitative investigation of the drivers of low-value testing and the development of interventions to improve preoperative testing practice, especially in locations where rates of LVT are high.

Abstract
BACKGROUND The recreational and medical use of cannabinoids has been increasing. While most studies and reviews have focused on the role of cannabinoids in the management of acute pain, no study has examined the postoperative outcomes of surgical candidates who are on cannabinoids preoperatively. This retrospective cohort study examined the impact of preoperative cannabinoid use on postoperative pain scores and pain-related outcomes in patients undergoing major orthopedic surgery. METHODS Outcomes of patients who had major orthopedic surgery at our hospital between April 1, 2015 and June 30, 2017 were reviewed. Data were obtained from Networked Online Processing of Acute Pain Information, a locally developed database for our Acute Pain Service. Propensity score matching was used to balance baselines variables including age, sex, type of surgery, history of depression or anxiety, and perioperative use of regional anesthesia between patients who reported use of cannabinoids and those not on this substance. Intensity of pain with movement in the early postoperative period (defined as up to 36 hours after surgery) was the primary outcome of this study. The secondary outcomes (all in early postoperative period) were pain at rest, opioid consumption, incidence of pruritus, nausea and vomiting, sedation, delirium, constipation, impairment of sleep and physical activity, patient satisfaction with analgesia, and the length of Acute Pain Service follow-up. RESULTS A total of 3793 patients were included in the study. Of these, 155 patients were identified as being on cannabinoids for recreational or medical indications in the preoperative period. After propensity score matching, we compared data from 155 patients who were on cannabinoids and 155 patients who were not on cannabinoids. Patients who were on preoperative cannabinoids had higher pain numerical rating score (median [25th, 75th percentiles]) at rest (5.0 [3.0, 6.1] vs 3.0 [2.0, 5.5], P = .010) and with movement (8.0 [6.0, 9.0] vs 7.0 [3.5, 8.5], P = .003), and a higher incidence of moderate-to-severe pain at rest (62.3% vs 45.5%, respectively, P = .004; odds ratio, 1.98; 95% CI, 1.25-3.14) and with movement (85.7% vs 75.2% respectively, P = .021; odds ratio, 1.98; 95% CI, 1.10-3.57) in the early postoperative period compared to patients who were not on cannabinoids. There was also a higher incidence of sleep interruption in the early postoperative period for patients who used cannabinoids. CONCLUSIONS This retrospective study with propensity-matched cohorts showed that cannabinoid use was associated with higher pain scores and a poorer quality of sleep in the early postoperative period in patients undergoing major orthopedic surgery.

Elevated preoperative Galectin-3 is associated with acute kidney injury after cardiac surgery. BMC Nephrol 2018; 19:280. [PMID: 30342486 PMCID: PMC6195960 DOI: 10.1186/s12882-018-1093-0] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2018] [Accepted: 10/09/2018] [Indexed: 01/15/2023] Open
Abstract
BACKGROUND Previous research suggests that novel biomarkers may be used to identify patients at increased risk of acute kidney injury following cardiac surgery. The purpose of this study was to evaluate the relationship between preoperative levels of circulating Galectin-3 (Gal-3) and acute kidney injury after cardiac surgery. METHODS Preoperative serum Gal-3 was measured in 1498 patients who underwent coronary artery bypass graft (CABG) surgery and/or valve surgery as part of the Northern New England Biomarker Study between 2004 and 2007. Preoperative Gal-3 levels were measured using multiplex assays and grouped into terciles. Univariate and multinomial logistic regression was used to assess the predictive ability of Gal-3 terciles and AKI occurrence and severity. RESULTS Before adjustment, patients in the highest tercile of Gal-3 had a 2.86-greater odds of developing postoperative KDIGO Stage 2 or 3 (p < 0.001) and 1.70-greater odds of developing KDIGO Stage 1 (p = < 0.001), compared to the first tercile. After adjustment, patients in the highest tercile had 2.95-greater odds of developing KDIGO Stage 2 or 3 (p < 0.001) and 1.71-increased odds of developing KDIGO Stage 1 (p = 0.001), compared to the first tercile. Compared to the base model, the addition of Gal-3 terciles improved discriminatory power compared to without Gal-3 terciles (test of equality = 0.042). CONCLUSION Elevated preoperative Gal-3 levels significantly improves predictive ability over existing clinical models for postoperative AKI and may be used to augment risk information for patients at the highest risk of developing AKI and AKI severity after cardiac surgery.

Pre-kidney transplant lower extremity impairment and transplant length of stay: a time-to-discharge analysis of a prospective cohort study. BMC Geriatr 2018; 18:246. [PMID: 30340462 PMCID: PMC6194663 DOI: 10.1186/s12877-018-0940-y] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2017] [Accepted: 10/09/2018] [Indexed: 12/21/2022] Open
Abstract
BACKGROUND Few objective tests can be performed at admission for kidney transplantation [KT] to discern risk of increased length of stay [LOS], which is important for patient counseling and is associated with increased costs and mortality. The short physical performance battery [SPPB] is an easily administered, potentially modifiable, 3-part test of lower extremity function. SPPB score is associated with longer hospital LOS in older adults, and may provide similar utility in KT recipients given that ESRD is a disease of accelerated aging. The aim of this study was to characterize the association between SPPB-derived lower extremity function and LOS. METHODS The SPPB was administered at KT admission in a prospective cohort of 595 recipients (8/2009-6/2016). The independent association between SPPB impairment (score ≤ 10) and LOS was tested with an adjusted conventional generalized gamma parametric survival model. RESULTS Impaired recipients experienced longer LOS (median: 10 vs. 8 days; P < 0.001) with the greatest difference in percent discharged on day 10 (impaired: 54.5%, unimpaired: 73.3%). Discharge typically took 13% longer in the impaired group (relative time = 1.13; 95%CI: 1.05, 1.21, P = 0.001). Discharge for impaired recipients compared to unimpaired was least likely at day 5 (hazard ratio = 0.71; 95% CI:0.68, 0.74, P < 0.001). No differences in the SPPB impairment-LOS relationship were found by age (interaction P = 0.74). CONCLUSIONS Pre-KT SPPB impairment was independently associated with longer LOS regardless of age, indicating that it is a useful, objective tool for pre-KT risk assessment in younger and older recipients that may help inform discharge planning.

Abstract
BACKGROUND Biological phenotypes have been identified within several heterogeneous pulmonary diseases, with potential therapeutic consequences. OBJECTIVE To assess whether distinct biological phenotypes exist within surgical patients, and whether development of postoperative pulmonary complications (PPCs) and subsequent dependence of intra-operative positive end-expiratory pressure (PEEP) differ between such phenotypes. SETTING Operating rooms of six hospitals in Europe and USA. DESIGN Secondary analysis of the 'PROtective Ventilation with HIgh or LOw PEEP' trial. PATIENTS Adult patients scheduled for abdominal surgery who are at risk of PPCs. INTERVENTIONS Measurement of pre-operative concentrations of seven plasma biomarkers associated with inflammation and lung injury. MAIN OUTCOME MEASURES We applied unbiased cluster analysis to identify biological phenotypes. We then compared the proportion of patients developing PPCs within each phenotype, and associations between intra-operative PEEP levels and development of PPCs among phenotypes. RESULTS In total, 242 patients were included. Unbiased cluster analysis clustered the patients within two biological phenotypes. Patients with phenotype 1 had lower plasma concentrations of TNF-α (3.8 [2.4 to 5.9] vs. 10.2 [8.0 to 12.1] pg ml; P < 0.001), IL-6 (2.3 [1.5 to 4.0] vs. 4.0 [2.9 to 6.5] pg ml; P < 0.001) and IL-8 (4.7 [3.1 to 8.1] vs. 8.1 [6.0 to 13.9] pg ml; P < 0.001). Phenotype 2 patients had the highest incidence of PPC (69.8 vs. 34.2% in type 1; P < 0.001). There was no interaction between phenotype and PEEP level for the development of PPCs (43.2% in high PEEP vs. 25.6% in low PEEP in phenotype 1, and 73.6% in high PEEP and 65.7% in low PEEP in phenotype 2; P for interaction = 0.503). CONCLUSION Patients at risk of PPCs and undergoing open abdominal surgery can be clustered based on pre-operative plasma biomarker concentrations. The two identified phenotypes have different incidences of PPCs. Biologic phenotyping could be useful in future randomised controlled trials of intra-operative ventilation. TRIAL REGISTRATION The PROtective Ventilation with HIgh or LOw PEEP trial, including the substudy from which data were used for the present analysis, was registered at ClinicalTrials.gov (NCT01441791).

Surgical management of Charcot neuroarthropathy of the ankle and hindfoot in patients with diabetes. Diabetes Metab Res Rev 2016; 32 Suppl 1:292-6.

Abstract
BACKGROUND Charcot neuroarthropathy (CN) of the ankle and hindfoot (Sanders/Frykberg Type IV) is challenging to treat surgically or nonsurgically. The deformities associated with ankle/hindfoot CN are often multiplanar, resulting in sagittal, frontal and rotational malalignment. In addition, shortening of the limb often occurs from collapse of the distal tibia, talus and calcaneus. These deformities also result in significant alterations in the biomechanics of the foot. For example, a varus ankle/hindfoot results in increased lateral column plantar pressure of the foot, predisposing the patient to lateral foot ulceration. Collapse of the talus, secondary to avascular necrosis or neuropathic fracture, further accentuates these deformities and contributes to a limb-length inequality. SURGICAL MANAGEMENT The primary indication for surgical reconstruction is a nonbraceable deformity associated with instability. Other indications include impending ulceration, inability to heal an ulcer, recurrent ulcers, presence of osteomyelitis and/or significant pain. Arthrodesis of the ankle and/or hindfoot is the method of choice when surgically correcting CN deformities in this region. The choice of fixation (i.e. internal or external fixation) depends on largely on the presence or absence of active infection and bone quality. CONCLUSION Surgical reconstruction of ankle and hindfoot CN is associated with a high rate of infectious and noninfectious complications. Despite this high complication rate, surgeons embarking on surgical reconstruction of ankle and hindfoot CN should strive for limb salvage rates approximating 90%. Preoperative measures that can improve outcomes include assessment of vascular status, optimization of glycemic control, correction of vitamin D deficiency and cessation of tobacco use.

Preoperative Planning in Orthopaedic Surgery. Current Practice and Evolving Applications. BULLETIN OF THE HOSPITAL FOR JOINT DISEASE (2013) 2015; 73:257-268.

Abstract
Preoperative planning is an essential prerequisite for the success of orthopaedic procedures. Traditionally, the exercise has involved the written down, step by step "blueprint" of the surgical procedure. Preoperative planning of the technical aspects of the orthopaedic procedure has been performed on hardcopy radiographs using various methods such as copying the radiographic image on tracing papers to practice the planned interventions. This method has become less practical due to variability in radiographic magnification and increasing implementation of digital imaging systems. Advances in technology along with recognition of the importance of surgical safety protocols resulted in widespread changes in orthopaedic preoperative planning approaches. Nowadays, perioperative "briefings" have gained particular importance and novel planning methods have started to integrate into orthopaedic practice. These methods include using software that enables surgeons to perform preoperative planning on digital radiographs and to construct 3D digital models or prototypes of various orthopaedic pathologies from a patient's CT scans to practice preoperatively. Evidence-to-date suggests that preoperative planning and briefings are effective means of favorably influencing the outcomes of orthopaedic procedures.

National trends and complication rates for invasive extraoperative electrocorticography in the USA. J Clin Neurosci 2015; 22:823-7.

Abstract
Invasive electrocorticography (ECoG) is used in patients when it is difficult to localize epileptogenic foci for potential surgical resection. As MR neuroimaging has improved over the past decade, we hypothesized the utilization of ECoG diminishing over time. Using the USA Nationwide Inpatient Sample, we collected demographic and complication data on patients receiving ECoG over the years 1988-2008 and compared this to patients with medically refractory epilepsy during the same time period. A total of 695 cases using extraoperative ECoG were identified, corresponding to 3528 cases nationwide and accounting for 1.1% of patients with refractory epilepsy from 1988-2008. African Americans were less likely to receive ECoG than whites, as were patients with government insurance in comparison to those with private insurance. Large, urban, and academic hospitals were significantly more likely to perform ECoG than smaller, rural, and private practice institutions. The most frequent complication was cerebrospinal fluid leak (11.7%) and only one death was reported from the entire cohort, corresponding to an estimated six patients nationally. Invasive ECoG is a relatively safe procedure offered to a growing number of patients with refractory epilepsy each year. However, these data suggest the presence of demographic disparities in those patients receiving ECoG, possibly reflecting barriers due to race and socioeconomic status. Among patients with nonlocalized seizures, ECoG often represents their only hope for surgical treatment. We therefore must further examine the indications and efficacy of ECoG, and more work must be done to understand if and why ECoG is preferentially performed in select socioeconomic groups.

Abstract
The introduction of laparoscopy in the surgeon's armamentarium was in fact a "revolution in the history of surgery". Since this technique involves insufflation of carbon dioxide it produces several pathophysiological changes which have to be understood by the anaesthesiologist who can modify the anaesthesia technique accordingly. Advantages of laparoscopy include reduced pain, small scars and early return to work. Certain complications specific to laparoscopic surgery are due to carboperitoneum and increased intra-abdominal pressure. Venous air embolism, although very rare, can be lethal if not managed promptly. Other complications include subcutaneous emphysema, haemodynamic compromise and arrhythmias. Although associated with minimal postoperative morbidity, postoperative pain, nausea and vomiting can be quite problematic. The limitations of laparoscopy have been overcome by the introduction of robotic surgery. There are important implications for the anaesthesiologist during robotic surgeries which have to be practiced accordingly. Robotic surgery has a learning curve for both the surgeon and the anaesthesiologist. The robot is bulky, and cannot be disengaged after docking. Therefore it is important that the anaesthetized patient remains immobile throughout surgery and anaesthesia is reversed only after the robot has been disengaged at the end of surgery. Advances in laparoscopy and robotic surgery have modified anaesthetic techniques too.

Abstract
Rectal cancer management improved results in the last thirty-five applying new integrated treatment options. Preoperative radiochemotherapy or radiotherapy alone joined to the modern surgery gaining significant improvement of outcomes. Nevertheless, a definitive conclusion about superiority of one on the other in term of survival and toxicity is still lacking, and further improvement is in general required and seems obtainable. The need for a wide sharing of the accumulated knowledge is represented by the consensus conferences that over the years summarizes the state of the art for the management of rectal cancer. One of the most promising opportunities comes from the attempt of characterization of the tumor heterogeneity. An always-increasing number of new parameters come from different sources including genomic, imaging, pathological features and many others. The need of new informatics technologies able to handle and continuously incorporate new inputs derived from the evidences is also imperative. The combined use of large shared databases and "learning models" could allow generating and rapidly testing new hypotheses, providing further survival improvement in the next years.

Abstract
BACKGROUND Preoperative laboratory testing is commonplace in the clinical setting and is often utilized at surgeon discretion. We searched the American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) data set to determine the impact of preoperative laboratory testing in ambulatory plastic surgery patients. OBJECTIVE The authors assess the utilization and predictive value of preoperative laboratory testing in outpatient plastic surgery procedures. METHODS Patients undergoing ambulatory plastic surgery were identified from the 2005 to 2010 NSQIP databases. Laboratory tests were categorized by group: hematologic, chemistry, coagulation, and liver function tests (LFT). We defined complications in 2 groups: major postoperative and wound complications. Multivariate analyses were used to identify patient characteristics associated with testing and to assess the ability of laboratory testing to predict postoperative complications. RESULTS A total of 5359 (62.0%) patients underwent testing; 881 (16.4%) tests were performed on the day of surgery. In patients with no defined NSQIP comorbidities, 59.4% underwent preoperative testing and had a significantly lower rate of abnormal findings (33.4% vs 25.3%, P < .0001). In multivariate analyses, testing was associated with older age, American Society of Anesthesiologists class >2, Hispanic or African American race, body contouring procedures, epidural or spinal procedures, and with diabetes, hypertension, and cancer. Major complications occurred in 0.34% of patients. Our analysis demonstrated that neither testing nor abnormal results were associated with postoperative complications, either major (P = .178) or wound (P = .150). CONCLUSIONS We found no association between abnormal laboratory testing and postoperative morbidity. Preoperative testing in low-risk ambulatory plastic surgery patients may be costly and has limited direct clinical benefit.

Abstract
OBJECTIVE To analyze trends in utilization of pre-surgical evaluations including video-EEG (VEEG) monitoring, intracranial EEG (IEEG) monitoring, and epilepsy surgery from 1998 to 2009 in the U.S. METHODS Data from the Nationwide Inpatient Sample were used to identify admissions for pre-surgical evaluations and surgery. Surgical treatment of epilepsy was identified by the presence of primary ICD-9-CM procedure codes 01.52 (hemispherectomy), 01.53 (lobectomy), or 01.59 (other excision of the brain, including amygdalohippocampectomy). We calculated annual rates of pre-surgical evaluations and surgery based on published estimates of prevalence of epilepsy in the U.S. In addition, we examined variations by region and hospital characteristics, and conducted multivariable analysis to detect temporal trends, adjusting for changes in the population. Sensitivity analysis was also conducted using different algorithms to identify the study population and outcomes. RESULTS We detected an increase in the rate of hospitalizations related to intractable epilepsy. Similarly, we noted a significant increase in hospitalizations for VEEG monitoring, but not in IEEG monitoring or in surgery. Multivariable analysis and sensitivity analysis confirmed these results. In addition, there was a significant increase in the proportion of pre-surgical evaluations and surgery performed in non-teaching hospitals. CONCLUSIONS Despite the increase in VEEG monitoring, the availability of guideline and evidences demonstrating benefits of epilepsy surgery was not associated with a greater employment of surgery over time. Nevertheless, access to pre-surgical evaluations and epilepsy surgery is no longer limited to large medical centers.

Abstract
Background—
To evaluate indications and results of surgery for primary cardiac tumors in children.
Methods and Results—
Eighty-nine patients aged ≤18 years undergoing surgery for cardiac tumor between 1990 and 2005 from 16 centers were included retrospectively (M/F=41/48; median age 4.3 months, range 1 day to 18 years). Sixty-three patients (68.5%) presented with symptoms. Surgery consisted of complete resection in 62 (69.7%) patients, partial resection in 21 (23.6%), and cardiac transplant in 4 (4.5%). Most frequent histotypes (93.2%) were benign (rhabdomyoma, myxoma, teratoma, fibroma, and hemangioma). Postoperative complications occurred in 29.9%. Early and late mortality were 4.5% each (mean follow-up, 6.3±4.4 years); major adverse events occurred in 28.2% of the patients; 90.7% of patients are in New York Heart Association class I. There were no statistically significant differences in survival, postoperative complications, or adverse events after complete and partial resection in benign tumors other than myxomas. Cardiac transplant was associated significantly with higher mortality rate (
P=
0.006). Overall mortality was associated to malignancy (
P
=0.0008), and adverse events during follow-up (
P
=0.005).
Conclusions—
Surgery for primary cardiac tumors in children has good early and long-term outcomes, with low recurrence rate. Rhabdomyomas are the most frequent surgical histotypes. Malignant tumors negatively affect early and late survival. Heart transplant is indicated when conservative surgery is not feasible. Lack of recurrence after partial resection of benign cardiac tumors indicates that a less risky tumor debulking is effective for a subset of histotypes such as rhabdomyomas and fibromas.

Abstract
OBJECTIVE We sought to examine the evolution of surgical care for early-stage endometrial cancers and factors affecting use of laparoscopy. STUDY DESIGN Women with surgically managed early-stage endometrial cancer were divided into 2 groups corresponding to before and after addition of faculty with formal fellowship training in laparoscopic staging and access to a robotic surgery platform. RESULTS In all, 502 women were identified. Laparoscopic management increased from 24-69% between time periods (P < .0001). Performance of comprehensive surgical staging, and lymph node counts, increased (P < .0001) despite an increase in median body mass index (P = .001). A traditional "straight stick" technique was performed in 72% of laparoscopic cases during the later period. Laparoscopy patients had lower estimated blood losses and shorter hospital stays (each P < .0001) compared to laparotomy patients. CONCLUSION Addition of faculty with formal fellowship training in laparoscopic staging and access to a robotic surgery platform shifted management of early-stage endometrial cancer toward laparoscopy.

Fast-track surgery (FTS) is a set of protocols aimed to reduce the physiological burden of surgery thus improving outcomes. FTS aims to use evidence-based practice to reduce complications, improve post-operative quality of life and decrease hospital length of stay. This review seeks to examine the evidence base for protocols employed in colorectal surgery in the areas of pre-operative preparation, anaesthetic management, intraoperative and surgical factors and post-operative care. Despite the evidence that recovery after colorectal surgery can be enhanced by using these approaches, implementation of FTS protocols has been slow. Acceptance of FTS protocols by all members of the multi-disciplinary team and a change in organisational structure to accommodate structured peri-operative care, are imperative to implementation.

Abstract
Heart transplantation (HTx) started in 1987 at two university hospitals (CHUV, HUG) in the western part of Switzerland, with 223 HTx performed at the CHUV until December 2010. Between 1987 and 2003, 106 HTx were realized at the HUG resulting in a total of 329 HTx in the western part of Switzerland. After the relocation of organ transplantation activity in the western part of Switzerland in 2003, the surgical part and the early postoperative care of HTx remained limited to the CHUV. However, every other HTx activity are pursued at the two university hospitals (CHUV, HUG). This article summarizes the actual protocols for selection and pre-transplant follow-up of HTx candidates in the western part of Switzerland, permitting a uniform structure of pretransplant follow-up in the western part of Switzerland.

Abstract
OBJECTIVES To evaluate whether patients with Cushing's syndrome (CS) had i) changes in coagulative and fibrinolytic parameters associated with CS activity and ii) higher prevalence of venous thromboembolic events (VTE). DESIGN Prospective study conducted on patients with CS evaluated at diagnosis and 12 months after surgery. PATIENTS AND METHODS Forty patients with active CS (36 with Cushing's disease (CD) and 4 with an adrenal adenoma) were evaluated. Forty normal subjects and 70 patients with non-ACTH-secreting pituitary adenomas served as controls. All patients and controls underwent an assessment of coagulation and fibrinolysis indexes before and after surgery. RESULTS CS patients at baseline had a hypercoagulative phenotype when compared with normal subjects (activated partial thromboplastin time (aPTT), fibrinogen, D-Dimer, von Willebrand factor (VWF), plasminogen activator inhibitor 1 (PAI-1 or SERPINE1), antithrombin III (ATIII or SERPINC1), P<0.0001, α(2) antiplasmin, P=0.0004, thrombin-antithrombin complex (TAT), P=0.01, factor IX (F9), P=0.03). Patients with still active disease after surgery had higher coagulative parameters than those in remission (VWF (P<0.0001), PAI-1 (P=0.004), TAT (P=0.0001), ATIII (P=0.0002) and α(2) antiplasmin (or SERPINF2; P=0.006)), whereas aPTT levels (P=0.007) were significantly reduced. VTE occurred in three patients with CD (7.5%): one had a pulmonary embolism and two patients had a deep venous thrombosis; no patients submitted to transsphenoidal surgery for non-Cushing's pituitary adenoma had VTE (P=0.04). CONCLUSIONS Patients with CS have a procoagulative phenotype due to cortisol-associated changes in haemostatic and fibrinolytic markers, leading to increased incidence of VTE. Thromboprophylaxis seems to be appropriated in patients with active disease, particularly in the postoperative period.

Abstract
Endometriosis is a major health problem, because of difficult diagnosis and limited therapies available. The surgical approach is done by very specialised surgeons, doing classical or laparoscopic ablative interventions. This article is an up-to date evaluation of medical treatment, reviewing the hormonal drugs (contraceptives, progestatives, GnRH analogues) and non-hormonal ones (anti-aromatase, anti-progestative, anti-tissular growth factors). The conclusion is that the medical treatment should be used in well selected cases, and adapted regimens, choosing among continuous contraceptives, intrauterine devices with levonorgestrel, or aromatase inhibitors. The main objective in this cases is rarely the complete cure, but more frequently optimal timing before surgery.

Abstract
BACKGROUND Diffusion tensor MRI fiber tractography (DTT) is the first non-invasive in vivo technique for delineating specific white matter (WM) tracts. In cerebral neoplasm, DTT can be used to illustrate the relationship of the tumor with respect to adjacent WM trajectories. METHODS Fiber tractography was used in this study to assess tumor-induced changes in WM trajectories in three cases of cerebral neoplasm: glioblastoma multiforme, meningioma, and anaplastic astrocytoma. RESULTS Three patterns of WM alteration were identified: 1) disruption, 2) displacement, and 3) infiltration. Tumor disruption of WM tracts was observed in glioblastoma multiforme, which terminated fibers crossing the corpus callosum. In meningioma, DTT illustrated bulk displacement of the corticospinal tract in the affected hemisphere as well as preservation of the deviated axons. In anaplastic astrocytoma, fiber tracking demonstrated disruption of WM tracts at the tumor origin as well as intact axons through areas of tumor infiltration. CONCLUSIONS Fiber tracking results correlated with the clinical and histopathological features of the tumor. Larger case series will be required to determine if fiber tracking can add accuracy to existing imaging methods for grading tumors.

Abstract
This chapter is complementary to the others in this volume focusing on preoperative fasting routines. In it we discuss some of the issues in need of more research to define best practice. One of these is the role of fasting in emergency patients. Modern preoperative fasting recommendations almost exclusively deal with elective patients. In emergency patients preoperative fasting cannot secure gastric emptying to reduce the risk of pulmonary aspiration. Hence, surgery should be timed according to the urgency of the situation, and the patient should always be treated as if the stomach was full. More data are needed to better define what is going on in the gastrointestinal tract during the perioperative period in these patients. In certain patient groups--such as patients with diabetes, gastro-oesophageal reflux disease and/or obesity--the data are insufficient to give complete guidance to best practice. Preoperative fasting guidelines also affect fluid balance and perioperative fluid management, a topic of debate in recent years. In addition, carbohydrate-enriched fluids for oral use in the preoperative phase have been shown to have a positive effect on postoperative metabolism. Recent studies also suggest that the immune system would be less affected by surgery with such preparations. Last but not least, new scientific evidence alone is not enough to change daily practice. Active implementation of new evidence is also needed. To improve perioperative care, anaesthesiologists, surgeons and the nursing staff must work together.

Abstract
Eight cases of neurosurgical operations being performed on the wrong side were studied. Safeguards of confidentiality were used. In seven cases side marking was not done and the surgeons felt that had it been done, the mistake would have or may have been prevented. In all but one case the surgeon's normal side check was omitted. Distracting circumstances contributed to the checks being omitted in these seven cases. In the one case where the check was carried out the mistake was made because the patient had been marked on the wrong side. In no case was the mistake made because of ambiguous or absent site data in the imaging or notes. It is concluded that to prevent these mistakes emphasis should be placed on ensuring that the preoperative site check is completed more than on ensuring that unambiguous side information is available in the notes and imaging.

Abstract
Functional MRI (fMRI) has had a major impact in cognitive neuroscience. fMRI now has a small but growing role in clinical neuroimaging, with initial applications to neurosurgical planning. Current clinical research has emphasized novel concepts for clinicians, such as the role of plasticity in recovery and the maintenance of brain functions in a broad range of diseases. There is a wider potential for clinical fMRI in applications ranging from presymptomatic diagnosis, through drug development and individualization of therapies, to understanding functional brain disorders. Realization of this potential will require changes in the way clinical neuroimaging services are planned and delivered.

Abstract
BACKGROUND Aneurysmal subarachnoid hemorrhage is a devastating disease that is followed by a marked stress response affecting other organs besides the brain. The aim in the management of patients with aSAH is not only to prevent rebleedings by treating the aneurysm by either microneurosurgery or endovascular surgery, but also to evacuate acute space-occupying hematomas and to treat hydrocephalus. METHODS This review is based on the experience of the authors in the management of more than 7500 patients with aSAH treated in the Department of Neurosurgery at Helsinki University Central Hospital, Finland. RESULTS The role of the neuroanesthesiologist together with the neurosurgeon may begin in the emergency department to assess and stabilize the general medical and neurologic status of the patients. Early preoperative management of patients in the NICU, prevention of rebleeding, and providing a slack brain during microneurosurgical procedures are further steps. Postoperative management, prevention, and treatment of possible medical complications and cerebrovascular spasm are as necessary as high-quality microsurgery. CONCLUSION Multidisciplinary and professional teamwork is essential in the management of patients with cerebral aneurysms.

Abstract
Pediatric fasting guidelines are intended to reduce the risk of pulmonary aspiration of gastric contents and facilitate the safe and efficient conduct of anesthesia. Recent changes in these guidelines, while assuring appropriate levels of patient safety, have been directed at improving the overall perioperative experience for infants, children, and their parents. Now after nearly 15 years of practice worldwide, the relative safety and benefits of allowing clear liquids up to 2 hr prior to anesthesia for otherwise healthy children are well established. Shortened fasting periods for breast milk (3 hr), formula (4 hr) and light meals (6 hr) are supported by accumulated experience and an evolving literature that includes evidence of minimal gastric fluid volumes (GFVs) at the time of surgery. Ideal fasting intervals for children with disorders that may affect gastrointestinal transit have yet to be determined.

Abstract
In the past few years, major improvements and new technologies have been proposed and applied in esophageal surgery. Its evolution depended not only on a thorough knowledge of surgical anatomy and technique, but also on important developments in pre- and postoperative care. Esophageal resection for cancer is still associated with high morbidity and mortality. Postoperative complications may be either patient or surgeon related. Patient-related factors include age, malnutrition, immunodepression and associated diseases. The surgeon-related factors are surgical experience, hospital volume and multidisciplinary approach. Preoperative evaluation is defined as the process of clinical assessment that precedes the delivery of anesthesia. The principle is to gain information concerning patients that leads to modification of their management, and improves the outcome from surgery.

Abstract
Social work's potential role in preoperative evaluations was generally unheard of only 15 years ago, as it was considered the domain of direct health care professionals such as nurses and surgeons. Social workers have traditionally focused on the peri- and posttransplant phases. However, clinical social workers are playing an increasingly vital role in the care and psychosocial evaluation of potential kidney recipients and donors. Caring for and evaluating potential kidney recipients includes myriad unique clinical and personal challenges. This article's aim is to help clinicians gain a better clinical picture and assessment of people who choose to participate as kidney recipients by using a clinical interview protocol. Using this protocol with potential kidney recipients and their collaterals (family members, peer associates, clergy, and so forth) clarifies internal and external motivations and issues. Furthermore, using such a protocol can help clinicians ascertain potential barriers and obstacles that could interfere with a patient's compliance and can perhaps help clinicians deal with such obstacles in a more comprehensive manner. Finally, this article also attempts to illuminate the ethical complexities involved in choosing to be a potential kidney recipient.

Abstract
OBJECT Biopsy targeting based on MR imaging alone may fail to identify malignant areas in brain gliomas. Considering the differences in relative Cerebral Blood Volume (rCBV) ratios reported among tumour grades, we evaluated whether perfusion-weighted MR imaging (PWI) could usefully implement the routine preoperative imaging by detecting those areas bearing a higher yield for malignancy to guide the stereotactic biopsy or the surgical removal. CLINICAL MATERIAL AND METHODS We studied a series of 55 consecutive patients with newly diagnosed brain glioma using both conventional MR imaging and PWI in the preoperative assessment. The pathological diagnosis was established by stereotactic biopsy in 29 cases and by craniotomy in 24 cases. We evaluated the patient survival to detect undergrading. DISCUSSION Independent from contrast-enhancement, perfusion-weighted MR imaging improved the target selection in stereotactic biopsy guidance and the removal of malignant areas in tumours amenable to surgery. Particularly sensitive to the perfused part of the tumour as to small regional changes, rCBV maps allowed a better detection of malignant areas. The rCBV ratios correlated significantly to the tumour grade and the final outcome (p < 0.01). CONCLUSIONS We found PWI valuable in the preoperative assessment of brain gliomas, discriminating high from low-grade gliomas. PWI can easily be performed on widely available MR imaging systems as part of the routine imaging of gliomas.
