Ustekinumab as induction and maintenance therapy for ulcerative colitis - national extended follow-up and a review of the literature. Expert Opin Drug Saf 2024; 23:449-456. [PMID: 37909484 DOI: 10.1080/14740338.2023.2278686] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2023] [Accepted: 09/15/2023] [Indexed: 11/03/2023]
Abstract
INTRODUCTION Ustekinumab use in ulcerative colitis had shown low adverse event and high persistence rates to 3 years via the UNIFI long-term extension study. Outcomes beyond 3 years have not been previously described. We describe the safety signals of the entire UNIFI Australian population beyond 3 years. METHODS This retrospective multicenter observational cohort study recruited from all Australian UNIFI centers. The primary outcome was safety via adverse events. Secondary outcomes included the clinical relapse rate on ustekinumab, and the need to switch from ustekinumab to an alternate agent. RESULTS There were 14 patients [11 male, mean age 47 (±14) years], with a median diagnosis of 10.8 (±4.5) years prior to UNIFI enrollment. Median follow-up was 298 weeks (5.7 years) (Interquartile range (IQR): 220-311 weeks). Within the long-term extension, there were three serious adverse events and one minor event. 42.9% (6/14) patients had clinical relapses, of which clinical remission was recaptured in 83.3% (5/6). 85.7% (12/14) persisted on ustekinumab in the long-term, with 7.1% (1/14) electively ceasing ustekinumab and 7.1% (1/14) changed from ustekinumab due to clinical relapse. CONCLUSION For moderate-to-severe UC in Australia, ustekinumab maintained efficacy beyond 3 years with a high persistence rate and no new safety signals. TRIAL REGISTRATION The trial is registered at ANZCTR (identifier: ACTRN12622001332718).

The Clinical Significance of Unplanned Coronary Artery Bypass Grafting in Aortic Root Replacement. J Cardiothorac Vasc Anesth 2024; 38:918-923. [PMID: 38307738 DOI: 10.1053/j.jvca.2024.01.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/11/2023] [Revised: 12/24/2023] [Accepted: 01/01/2024] [Indexed: 02/04/2024]
Abstract
OBJECTIVES Unexpected coronary artery bypass grafting (CABG) is occasionally required during aortic root replacement (ARR). However, the impact of unplanned CABG remains unknown. DESIGN A single-center, retrospective observational study. SETTING At university-affiliated tertiary hospital. PARTICIPANTS All patients who underwent ARR from 2011 through 2022. INTERVENTIONS Aortic root replacement with or without unplanned CABG. MEASUREMENTS AND MAIN RESULTS A total of 795 patients underwent ARR. Among them, 131 (16.5%) underwent planned concomitant CABG, and 34 (4.3%) required unplanned CABG. The most common indication of unplanned CABG was ventricular dysfunction (33.3%), followed by disease pathology (25.6%), anatomy (15.4%), and surgical complications (10.3%). A vein graft to the right coronary artery was the most commonly performed bypass. Infective endocarditis and aortic dissection were observed in 27.8% and 12.8%, respectively. Prior cardiac surgery was seen in 40.3%. The median follow-up period was 4.3 years. Unplanned CABG was not associated with operative mortality (odds ratio [OR] 1.54, 95% CI 0.33-7.16, p = 0.58) or long-term mortality (hazard ratio 0.91, 95% CI 0.44-1.89, p = 0.81). Body surface area smaller than 1.7 was independently associated with an increased risk of unplanned CABG (OR 4.51, 95% CI 1.85-11.0, p < 0.001). CONCLUSIONS Unplanned CABG occurred in 4.3% of patients during ARR, but was not associated with operative mortality or long-term mortality. A small body surface area was a factor associated with unplanned CABG.

Abstract
BACKGROUND The utility of perioperative intravenous lidocaine in improving postoperative pain control remains unclear. We aimed to compare postoperative pain outcomes in ERP abdominal surgery patients who did vs did not receive intravenous lidocaine. We hypothesized that patients receiving lidocaine would have lower postoperative pain scores and consume fewer opioids. METHODS We performed a retrospective cohort study of patients undergoing elective abdominal surgery at a single institution via an ERP from 2017 to 2018. Patients who received lidocaine in the 6 months prior to a lidocaine shortage were compared to those who did not receive lidocaine for 6 months following the shortage. The primary outcome measures were pain scores as measured on the visual analogue scale and opioid consumption as measured by oral morphine equivalents (OME). RESULTS We identified 1227 consecutive ERP abdominal surgery patients for inclusion (519 patients receiving lidocaine and 708 patients not receiving lidocaine). Demographics between the two cohorts were similar, with the following exceptions: more females, and more patients with a history of psychiatric diagnoses in the group that did not receive lidocaine. Adjusted, mixed linear models for both OME (P = .23) and pain scores (P = .51) found no difference between the lidocaine and no lidocaine groups. DISCUSSION In our study of ERP abdominal surgery patients, perioperative intravenous lidocaine did not offer improvement in postoperative pain scores or OME consumed. We therefore do not recommend the use of intravenous lidocaine as part of an ERP multimodal pain management strategy in abdominal surgery patients.

Role of Intraoperative Neuromonitoring to Predict Postoperative Delirium in Cardiovascular Surgery. J Cardiothorac Vasc Anesth 2024; 38:526-533. [PMID: 37838509 DOI: 10.1053/j.jvca.2023.09.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/22/2023] [Revised: 08/20/2023] [Accepted: 09/09/2023] [Indexed: 10/16/2023]
Abstract
OBJECTIVE Postoperative delirium (POD) can occur in up to 50% of older patients undergoing cardiovascular surgery, resulting in hospitalization and significant morbidity and mortality. This study aimed to determine whether intraoperative neurophysiologic monitoring (IONM) modalities can be used to predict delirium in patients undergoing cardiovascular surgery. DESIGN Adult patients undergoing cardiovascular surgery with IONM between 2019 and 2021 were reviewed retrospectively. Delirium was assessed multiple times using the Intensive Care Delirium Screening Checklist (ICDSC). Patients with an ICDSC score ≥4 were considered to have POD. Significant IONM changes were evaluated based on a visual review of electroencephalography (EEG) and somatosensory evoked potentials data and documentation of significant changes during surgery. SETTING University of Pittsburgh Medical Center hospitals. PARTICIPANTS Patients 18 years old and older undergoing cardiovascular surgery with IONM monitoring. MEASUREMENTS AND MAIN RESULTS Of the 578 patients undergoing cardiovascular surgery with IONM, 126 had POD (21.8%). Significant IONM changes were noted in 134 patients, of whom 49 patients had delirium (36.6%). In contrast, 444 patients had no IONM changes during surgery, of whom 77 (17.3%) patients had POD. Upon multivariate analysis, IONM changes were associated with POD (odds ratio 2.12; 95% CI 1.31-3.44; p < 0.001). Additionally, baseline EEG abnormalities were associated with POD (p = 0.002). CONCLUSION Significant IONM changes are associated with an increased risk of POD in patients undergoing cardiovascular surgery. These findings offer a basis for future research and analysis of EEG and somatosensory evoked potential monitoring to predict, detect, and prevent POD.

Outcomes after Perioperative Transient Ischemic Attack Following Cardiac Surgery. J Cardiovasc Dev Dis 2024; 11:27. [PMID: 38248897 PMCID: PMC10816235 DOI: 10.3390/jcdd11010027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2023] [Revised: 01/14/2024] [Accepted: 01/15/2024] [Indexed: 01/23/2024] Open
Abstract
Perioperative transient ischemic attacks (PTIAs) are associated with significantly increased rates of postoperative complications such as low cardiac output, atrial fibrillation, and significantly higher mortality in cardiac procedures. The current literature on PTIAs is sparse and understudied. Therefore, we aim to understand the effects of PTIA on hospital utilization, readmission, and morbidity. Using data on all the cardiac procedures at the University of Pittsburgh Medical Center from 2011 to 2019, fine and gray analysis was performed to identify whether PTIAs and covariables correlate with increased hospital utilization, stroke, all-cause readmission, Major Adverse Cardiac and Cerebrovascular Events (MACCE), MI, and all-cause mortality. Logistic regression for longer hospitalization showed that PTIA (HR: 2.199 [95% CI: 1.416-3.416] increased utilization rates. Fine and gray modeling indicated that PTIA (HR: 1.444 [95% CI: 1.096-1.902], p < 0.01) increased the rates of follow-up all-cause readmission. However, PTIA (HR: 1.643 [95% CI: 0.913-2.956] was not statistically significant for stroke readmission modeling. Multivariate modeling for MACCE events within 30 days of surgery (HR: 0.524 [95% CI: 0.171-1.605], p > 0.25) and anytime during the follow-up period (HR: 1.116 [95% CI: 0.825-1.509], p > 0.45) showed no significant correlation with PTIA. As a result of PTIA's significant burden on the healthcare system due to increased utilization, it is critical to better define and recognize PTIA for timely management to improve perioperative outcomes.

Digital Gangrene as a Paraneoplastic Manifestation of Peripheral T-cell Lymphoma Not Otherwise Specified Type. THE JOURNAL OF THE ASSOCIATION OF PHYSICIANS OF INDIA 2024; 72:99-102. [PMID: 38736082 DOI: 10.59556/japi.71.0370] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 05/14/2024]
Abstract
BACKGROUND Peripheral T cell lymphoma (PTCL), not otherwise specified (NOS) is a heterogenous group of predominantly nodal T cell lymphomas that generally presents with lymphadenopathy with or without extra nodal involvement. Acral vascular syndrome clinically presents as digital ischemia with Raynaud's phenomenon and acral cyanosis. Although, this condition is commonly associated with connective tissue disorder, smoking and vasculitis, its association with lymphoid malignancy is very rare. Here, we present a case report of a patient with digital gangrene of all toes and fingers as a presenting symptom of PTCL-NOS. CASE DESCRIPTION A 62 year old male presented with digital ischemia associated with pain, low grade fever, loss of appetite and significant weight loss of 6 kilograms over a period of 3 months. On examination, he was found to have bilateral inguinal and axillary lymph nodes with gangrenous changes over toes and fingers but peripheral pulses were palpable. On evaluation he had anemia, elevated ESR and CRP. CT angiogram revealed thinned out digital arteries with multifocal areas of narrowing. Patient was screened for other causes of digital gangrene and was tested negative for ANCA, ANA, cryoglobulins and viral markers. Lymph node biopsy with IHC was suggestive of peripheral T-cell lymphoma-NOS and was started on CHOP regimen. Lymph nodes size decreased and gangrenous changes resolved. CONCLUSION Though digital ischemia is a rare paraneoplastic presentation of lymphoma, it should be considered if there is a rapid progression of gangrene. Early initiation of chemotherapy may result in the reduction of further progression of digital gangrene and thus prevent permanent disability. In our patient, progression of gangrene was prevented even though it was an aggressive variant of T cell lymphoma.

REMAP Periop: a randomised, embedded, multifactorial adaptive platform trial protocol for perioperative medicine to determine the optimal enhanced recovery pathway components in complex abdominal surgery patients within a US healthcare system. BMJ Open 2023; 13:e078711. [PMID: 38154902 PMCID: PMC10759097 DOI: 10.1136/bmjopen-2023-078711] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Accepted: 11/23/2023] [Indexed: 12/30/2023] Open
Abstract
INTRODUCTION Implementation of enhanced recovery pathways (ERPs) has resulted in improved patient-centred outcomes and decreased costs. However, there is a lack of high-level evidence for many ERP elements. We have designed a randomised, embedded, multifactorial, adaptive platform perioperative medicine (REMAP Periop) trial to evaluate the effectiveness of several perioperative therapies for patients undergoing complex abdominal surgery as part of an ERP. This trial will begin with two domains: postoperative nausea/vomiting (PONV) prophylaxis and regional/neuraxial analgesia. Patients enrolled in the trial will be randomised to arms within both domains, with the possibility of adding additional domains in the future. METHODS AND ANALYSIS In the PONV domain, patients are randomised to optimal versus supraoptimal prophylactic regimens. In the regional/neuraxial domain, patients are randomised to one of five different single-injection techniques/combination of techniques. The primary study endpoint is hospital-free days at 30 days, with additional domain-specific secondary endpoints of PONV incidence and postoperative opioid consumption. The efficacy of an intervention arm within a given domain will be evaluated at regular interim analyses using Bayesian statistical analysis. At the beginning of the trial, participants will have an equal probability of being allocated to any given intervention within a domain (ie, simple 1:1 randomisation), with response adaptive randomisation guiding changes to allocation ratios after interim analyses when applicable based on prespecified statistical triggers. Triggers met at interim analysis may also result in intervention dropping. ETHICS AND DISSEMINATION The core protocol and domain-specific appendices were approved by the University of Pittsburgh Institutional Review Board. A waiver of informed consent was obtained for this trial. Trial results will be announced to the public and healthcare providers once prespecified statistical triggers of interest are reached as described in the core protocol, and the most favourable interventions will then be implemented as a standardised institutional protocol. TRIAL REGISTRATION NUMBER NCT04606264.

Evaluating a unique enhanced recovery protocol in laparoscopic donor nephrectomy: A single center experience. Clin Transplant 2023; 37:e15051. [PMID: 37335310 DOI: 10.1111/ctr.15051] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2022] [Revised: 05/24/2023] [Accepted: 06/07/2023] [Indexed: 06/21/2023]
Abstract
INTRODUCTION Enhanced recovery after surgery (ERAS) protocols have been associated with a reduction in opioid consumption and a hastening in recovery in abdominal surgery. However, their impact on laparoscopic donor nephrectomy (LDN) has not been fully elucidated. The aim of this study is to evaluate opioid consumption and other relevant outcome measures before and after implementation of a unique LDN ERAS protocol. METHODS 244 LDN patients were included in this retrospective cohort study. Forty-six underwent LDN prior to implementation of ERAS, whereas 198 patients received ERAS perioperative care. The primary outcome was daily oral morphine equivalent (OME) consumption averaged over the entire postoperative stay. Due to removal of preoperative oral morphine from the protocol partway through the study period, the ERAS group was further subdivided into morphine recipients and non-recipients for subgroup analysis. Secondary outcomes included the incidence of postoperative nausea and vomiting (PONV), length of stay, pain scores, and other relevant measures. RESULTS ERAS donors consumed significantly fewer average daily OMEs than Pre-ERAS donors (21.5 vs. 37.6, respectively; p < .0001). There were no statistically significant differences in OME consumption between morphine recipients and non-recipients. The ERAS group experienced less PONV (44.4% requiring one or more rescue antiemetic postoperatively, vs. 60.9% of Pre-ERAS donors; p = .008). CONCLUSIONS A protocol pairing lidocaine and ketamine with a comprehensive approach to preoperative PO intake, premedication, intraoperative fluid management and postoperative pain control is associated with reduced opioid consumption in LDN.

Abstract
BACKGROUND Perioperative stroke after cardiac surgical procedures carries significant morbidity. Dual intraoperative neurophysiological monitoring with electroencephalography (EEG) and somatosensory-evoked potentials detects cerebral hypoperfusion and predicts postoperative stroke in noncardiac procedures. We further evaluated preoperative risk factors and intraoperative neuromonitoring ability to predict postoperative stroke after cardiac operations. METHODS All patients who underwent cardiac operations with intraoperative neurophysiological monitoring from 2009 to 2020 at a single academic medical center were retrospectively analyzed. Patients with circulatory arrest were excluded. Risks factors analyzed were sex, age, tobacco use, hypertension, diabetes mellitus, dyslipidemia, atrial fibrillation, prior cerebrovascular accident, cerebrovascular disease, antiplatelet/anticoagulant use, abnormal somatosensory-evoked potentials and EEG baselines, and significant somatosensory-evoked potentials and EEG change as well as their permanence. Patients were divided into 2 groups by 30-day postoperative stroke occurrence. Univariate and multivariate logistical regressions were used for postoperative stroke significant predictors, and Kaplan-Meier curves estimated survival. RESULTS The study included 620 patients (67.6% men), mean age 65.1 ± 14.1 years, with stroke in 5.32%. In univariate analysis, diabetes (odds ratio [OR], 2.62) and permanence of EEG change (OR, 5.35) were each associated with increased postoperative stroke odds. In multivariate analysis, diabetes (OR, 2.64) and permanent EEG change (OR, 4.22) were independently significantly associated with postoperative stroke. Overall survival was significantly better for patients with no intraoperative neurophysiological monitoring changes (P < .005). CONCLUSIONS Permanent EEG change and diabetes were significant postoperative stroke predictors in cardiac operations. Furthermore, overall survival out to 10 years postoperatively was significantly higher in the group without intraoperative neurophysiological monitoring changes, emphasizing its important predictive role.

Abstract
BACKGROUND In this international, multicenter study of patients undergoing lung transplantation (LT), we explored the association between the amount of intraoperative packed red blood cell (PRBC) transfusion and occurrence of primary graft dysfunction (PGD) and associated outcomes. METHODS The Extracorporeal Life Support in LT Registry includes data on LT recipients from 9 high-volume (>40 transplants/y) transplant centers (2 from Europe, 7 from the United States). Adult patients who underwent bilateral orthotopic lung transplant from January 2016 to January 2020 were included. The primary outcome of interest was the occurrence of grade 3 PGD in the first 72 h after LT. RESULTS We included 729 patients who underwent bilateral orthotopic lung transplant between January 2016 and November 2020. LT recipient population tertiles based on the amount of intraoperative PRBC transfusion (0, 1-4, and >4 units) were significantly different in terms of diagnosis, age, gender, body mass index, mean pulmonary artery pressure, lung allocation score, hemoglobin, prior chest surgery, preoperative hospitalization, and extracorporeal membrane oxygenation requirement. Inverse probability treatment weighting logistic regression showed that intraoperative PRBC transfusion of >4 units was significantly ( P < 0.001) associated with grade 3 PGD within 72 h (odds ratio [95% confidence interval], 2.2 [1.6-3.1]). Inverse probability treatment weighting analysis excluding patients with extracorporeal membrane oxygenation support produced similar findings (odds ratio [95% confidence interval], 2.4 [1.7-3.4], P < 0.001). CONCLUSIONS In this multicenter, international registry study of LT patients, intraoperative transfusion of >4 units of PRBCs was associated with an increased risk of grade 3 PGD within 72 h. Efforts to improve post-LT outcomes should include perioperative blood conservation measures.

Abstract
The objective of this study was to identify the relationship between blood product transfusion and short-term morbidity and mortality following lung transplantation utilizing machine learning. Preoperative recipient characterstics, procedural variables, perioperative blood product transfusions, and donor charactersitics were included in the model. The primary composite outcome was occurrence on any of the following six endpoints: mortality during index hospitalization; primary graft dysfunction at 72 h post-transplant or the need for postoperative circulatory support; neurological complications (seizure, stroke, or major encephalopathy); perioperative acute coronary syndrome or cardiac arrest; and renal dysfunction requiring renal replacement therapy. The cohort included 369 patients, with the composite outcome occurring in 125 cases (33.9%). Elastic net regression analysis identified 11 significant predictors of composite morbidity: higher packed red blood cell, platelet, cryoprecipitate and plasma volume from the critical period, preoperative functional dependence, any preoperative blood transfusion, VV ECMO bridge to transplant, and antifibrinolytic therapy were associated with higher risk of morbidity. Preoperative steroids, taller height, and primary chest closure were protective against composite morbidity.

Abstract
BACKGROUND Single-center studies support benefits of venoarterial extracorporeal membrane oxygenation (VA-ECMO) as a method of intraoperative support. Propensity-matched data from a large cohort, however, are currently lacking. Therefore, our goal was to compare outcomes of intraoperative VA-ECMO and cardiopulmonary bypass (CPB) during bilateral lung transplantation (LTx) with a propensity analysis. METHODS We performed a retrospective analysis of 795 consecutive primary adult LTx patients (June 1, 2011-December 26, 2020) using no intraoperative support (n = 210), VA-ECMO (n = 150), or CPB (n = 197). Exclusion criteria included LTx on venovenous-ECMO, single/redo LTx, ex vivo lung perfusion, and concomitant solid-organ transplantation or cardiac procedure. Propensity analysis was performed comparing patients who underwent intraoperative CPB or VA-ECMO. RESULTS The propensity CPB group required more blood products at 72 hours (P = .02) and longer intensive care unit length of stay (P < .001) and ventilator dependence days (P < .001). There were no differences in cerebrovascular accident (P = 1), reintubation (P = .4), dialysis (P = .068), in-hospital mortality (P = .33), and 1-year (P = .67) and 3-year (P = .32) survival. The CPB group had a higher incidence of grade 3 primary graft dysfunction at 72 hours (P < .001). Neither support strategy was a predictor of 1- and 3-year mortality in our multivariable model (VA-ECMO, P = .72 and P = .57; CPB, P = .45 and P = .91, respectively). CONCLUSIONS Intraoperative VA-ECMO during lung transplantation was associated with fewer postoperative blood transfusions, shorter length of mechanical ventilation, and lower incidence of a grade 3 primary graft dysfunction at 72 hours. Although there were some differences in the postoperative course between the VA-ECMO and CPB groups, support type was not associated with differences in survival.

Abstract
OBJECTIVE To determine the impact of diastolic dysfunction (DD) on survival after routine cardiac surgery. DESIGN This was an observational study of consecutive cardiac surgeries from 2010 to 2021. SETTING At a single institution. PARTICIPANTS Patients undergoing isolated coronary, isolated valvular, and concomitant coronary and valvular surgery were included. Patients with a transthoracic echocardiogram (TTE) longer than 6 months prior to their index surgery were excluded from the analysis. INTERVENTIONS Patients were categorized via preoperative TTE as having no DD, grade I DD, grade II DD, or grade III DD. MEASUREMENTS AND MAIN RESULTS A total of 8,682 patients undergoing a coronary and/or valvular surgery were identified, of whom 4,375 (50.4%) had no DD, 3,034 (34.9%) had grade I DD, 1,066 (12.3%) had grade II DD, and 207 (2.4%) had grade III DD. The median (IQR) time of the TTE prior to the index surgery was 6 (2-29) days. Operative mortality was 5.8% in the grade III DD group v 2.4% for grade II DD, 1.9% for grade I DD, and 2.1% for no DD (p = 0.001). Atrial fibrillation, prolonged mechanical ventilation (>24 hours), acute kidney injury, any packed red blood cell transfusion, reexploration for bleeding, and length of stay were higher in the grade III DD group compared to the rest of the cohort. The median follow-up was 4.0 (IQR: 1.7-6.5) years. Kaplan-Meier survival estimates were lower in the grade III DD group than in the rest of the cohort. CONCLUSIONS These findings suggested that DD may be associated with poor short-term and long-term outcomes.

[PMID: 36347730 DOI: 10.1053/j.jvca.2022.10.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/16/2022] [Revised: 09/24/2022] [Accepted: 10/05/2022] [Indexed: 11/06/2022]
Abstract
OBJECTIVES Poor pain control after cardiac surgery can be associated with postoperative complications, longer recovery, and development of chronic pain. The authors hypothesized that adding liposomal bupivacaine (LB) to plain bupivacaine (PB) will provide better and long-lasting analgesia when used for wound infiltration in median sternotomy. STUDY DESIGN Prospective, randomized, and double-blinded clinical trial. SETTING Single institution, tertiary care university hospital. PARTICIPANTS Adult patients who underwent elective cardiac surgery through median sternotomy. INTERVENTIONS A single surgeon performed wound infiltration of LB plus PB or PB into the sternotomy wound, chest, and mediastinal tube sites. MEASUREMENTS AND MAIN RESULTS Patients were followed up for 72 hours for pain scores, opioid consumption, and adverse events. Sixty patients completed the study for analysis (LB group [n = 29], PB group [n = 31]). Patient characteristics, procedural variables, and pain scores measured at specific intervals from 4 hours until 72 hours postoperatively did not reveal any significant differences between the groups. Mixed-model regression showed that the trend of mean pain scores at movement in the LB group was significantly (p = 0.01) lower compared with the PB group. Opioid consumption over 72 hours was not significantly different between the 2 groups (oral morphine equivalents; median [interquartile range], 139 [73, 212] mg in LB v 105 [54, 188] mg in PB, p = 0.29). Recovery characteristics and adverse events were comparable. CONCLUSIONS LB added to PB for sternotomy wound infiltration during elective cardiac surgery did not significantly improve the quality of postoperative analgesia.

Abstract
Carotid revascularization is performed to prevent cerebrovascular events in patients with symptomatic (>50%) and asymptomatic high degree (>70%) carotid stenosis. As this operation carries significant risks for perioperative stroke, careful selection of patients who will benefit from the procedure is essential. Certain plaque characteristics, including texture, are associated with increased tendency for rupture and can be used to identify high-risk patients. Medical therapy, carotid endarterectomy, and carotid stenting are the mainstays for patient management. With careful selection of patients, all anesthesia techniques (general anesthesia, monitored anesthesia care, and regional anesthesia) can be used safely for these revascularization procedures.

Abstract
The concept of "pre-habilitation" comprises screening for and identification of pre-existing disorders followed by medical optimization. This is performed for many types of surgeries, but may have profound impacts on outcomes, particularly in cardiac surgery given the multiple comorbidities typically carried by these patients. Components of pre-habilitation include direct medical intervention by preoperative specialists as well as significant care coordination and shared decision-making. In this second part of a two-part review, the authors describe existing evidence to support the optimization of various preoperative problems and present a few institutional protocols utilized at out center for cardiac presurgical care. This second installment will focus on alcohol and smoking cessation and the management of frailty, malnutrition, respiratory disease, and depression.

O-027 Small extracellular vesicle (sEV) protein cargo as potential biomarker for endometriosis. Hum Reprod 2022.

Abstract
Abstract
Study question
Can an endometriosis-specific protein signature in small extracellular vesicles (sEV) from peritoneal fluid (PF) be utilised as a non-invasive biomarker of the condition?
Summary answer
Yes, potentially. We found differences in the concentrations and protein cargo of PF-derived sEV between controls and endometriosis samples, most notably in CD44 expression.
What is known already
Endometriosis, defined as endometrial-like tissue outside the uterus, causes pain and/or subfertility in 10% of reproductive age women. The cause is unknown, resulting in inadequate diagnostic methods and treatment options. There is no clinically relevant biomarker for endometriosis yet. Small extracellular vesicles (sEV), produced by virtually every cell, have been described in diseases such as cancer, diabetes, and pre-eclampsia, and could similarly be important in endometriosis. We previously identified sEV in PF of women with endometriosis, and here investigated the protein cargo of PF sEV as biomarker of the disease.
Study design, size, duration
PF samples were obtained from participants in the ENDOX study, Endometriosis CaRe Centre, Nuffield Department of Women’s and Reproductive Health, University of Oxford (REC ref. 09/H0604/58) according to WERF EPHect standards. Women between 18-49 years of age (n = 63) who had undergone diagnostic laparoscopy were classified according to cycle phase (proliferative/secretory/menstrual) and severity of endometriosis (ASRM stages I+II or stages III+IV). Exclusion criteria were hormonal treatment, malignancy, pregnancy, breastfeeding, and inability to understand the consent form.
Participants/materials, setting, methods
The participant groups were control proliferative, n = 7; control secretory, n = 9; control menstrual, n = 3; StI+II proliferative, n = 8; StI+II secretory, n = 10; St1+II menstrual, n = 7; StIII+IV proliferative, n = 5; StIII+IV secretory, n = 11; StIII+IV menstrual, n = 3. 1 mL PF was centrifuged to remove cells, debris, and microvesicles. sEV were isolated using size exclusion chromatography (SEC) and analysed by nanoparticle tracking analysis (NTA), immunoblotting, and mass spectrometry (LC-MS/MS).
Main results and the role of chance
We confirmed the presence of exosomes in PF from women at different stages of endometriosis and from disease-free patients at different menstrual cycle phases by NTA, immunoblotting and mass spectrometry. Enriched sEV were positive for ALIX, CD9, and syntenin. The mode size of PF particles from women with endometriosis was 115 ± 15.5 nm, whereas in non-endometriotic women it was 95 ± 17.3 nm (n.s.). sEV concentrations were higher in endometriosis compared to controls, and highest in stage III-IV endometriosis, followed by stage I-II endometriosis and controls, irrespective of menstrual cycle phase (P = 0.0210). sEV concentration in stage III-IV endometriosis decreased consistent with a transition from proliferative to secretory phase. Likewise, PF-derived sEV numbers within stage I-II endometriosis samples increased, as these samples transitioned from proliferative to secretory cycle phases. Proteomic analysis showed distinct distribution patterns of proteins within endometriosis PF-derived sEVs compared to controls. Consistent with earlier studies, we found CD44 as an sEV protein uniquely within the endometriosis population and contributing significantly to the separation of endometriosis and control samples by the highest variable importance projection (VIP) score in our data set.
Limitations, reasons for caution
The main limitation of this study is the small number of samples across the different groups, and the limited amount of PF per sample.
Wider implications of the findings
PF-derived sEV differ between endometriosis and control patients. Concentrations vary regardless of cycle phase and disease stage, and this difference appears to be reflected in the proteomics analysis. The presence of CD44 within sEV could help diagnose endometriosis.

Abstract
BACKGROUND Acute kidney injury (AKI) is a common postoperative complication in bilateral orthotopic lung transplant (BOLTx) recipients, but the contribution of intraoperative variables is not well defined. The authors hypothesized that intraoperative hypotension as well as hypoxia and vasopressor use would be associated with the development of postoperative AKI after BOLTx in patients without pre-existing renal dysfunction. METHODS The authors performed a retrospective analysis of patients undergoing BOLTx at a single center between 2013 and 2017. Intraoperative variables of hemodynamics included duration of mean arterial pressure <55, <60, and <65 mm Hg; duration of oxygen saturation <90%; and vasoactive-inotropic score (VIS). Associations between the occurrence of AKI and intraoperative hypotension, hypoxemia, and VIS were evaluated while controlling for significant confounding variables. RESULTS AKI occurred in 177 (72%) of 245 patients in postoperative days 1-7. Notable significant differences in univariate analyses included cumulative mechanical support time, maximum VIS, peripheral oxygen saturation <90% for >15 min, total minutes oxygen saturation <90%, and surgery duration in minutes. There was no significant difference in intraoperative hypotension measured as a duration >15 min for mean arterial pressure <55, <60, or <65 mm Hg. Multivariate logistic regression revealed preoperative creatinine (Odds ratio [OR], 7.77; confidence interval [CI], 1.96-30.83; P = 0.004), surgery duration (OR, 1.004; CI, 1.002-1.007; P = 0.002), and oxygen saturation (OR, 2.06; CI, 1.01-4.24; P = 0.049) <90% for >15 min to be independently associated with AKI. CONCLUSIONS This study revealed that >15 min of intraoperative hypoxia was independently associated with postoperative AKI after BOLTx.

Abstract
The use of intraoperative transesophageal echocardiography (TEE) has become the standard of care for most cardiac surgical procedures. There are guidelines established for training, practice, and quality improvement in perioperative TEE by the joint efforts of the American Society of Echocardiography and Society of Cardiovascular Anesthesiologists. Cardiac point-of-care ultrasound (POCUS) increasingly is being incorporated into anesthesiologists' training and practice. While a special "certification in Critical Care Echocardiography" was created by the National Board of Echocardiography in 2019, there currently exist no guidelines for training, certification, and practice of perioperative TTE by anesthesiologists. In this review, the authors describe the categories, indications and applications of perioperative TTE and provide a recommended sequence for performing an examination tailored to the evaluation of perioperative patients. Although the authors describe a protocol utilized at their institution, there are no standards described in the literature for PTTE. Cardiac anesthesiologists and cardiac anesthesia societies (Society of Cardiovascular Anesthesiologists, European Association of Cardiothoracic Anesthesiologists) must come forward to establish standards working in collaboration with echocardiography societies (American Society of Echocardiography, European Society of Cardiology).

Abstract
OBJECTIVE Enhanced recovery protocols (ERPs) utilize multi-modal analgesia regimens. Individual regimen components should be evaluated for their analgesic efficacy. We evaluated the effect of scheduled intravenous (IV) acetaminophen within an ERP on analgesia and recovery after a major abdominal surgery. DESIGN This study is a prospective, randomized, double-blinded clinical trial. SETTING The study setting was a tertiary care, academic medical center. SUBJECTS Adult patients scheduled for elective major abdominal surgical procedures. METHODS Patients in group A received 1g IV acetaminophen, while patients in group P received IV placebo every six hours for 48 hours postoperatively within an ERP. Pain scores, opioid requirements, nausea and vomiting, time to oral intake and mobilization, length of stay, and patient satisfaction scores were measured and compared. RESULTS From 412 patients screened, 154 patients completed the study (Group A: 76, Group P: 78). Primary outcome was the number of patients with unsatisfactory pain relief, defined as a composite of average Numeric Rating Scale (NRS) scores above 5 and requirement of IV patient-controlled analgesia for pain relief during the first 48 hours postoperatively, and was not significantly different between the two groups (33 (43.4%) in group A versus 42 (53.8%) patients in group P, p=0.20). Opioid consumption was comparable between two groups. Group A utilized significantly less postoperative rescue antiemetics compared to group P (41% vs. 58%, p= 0.02). CONCLUSIONS Scheduled administration of IV acetaminophen did not improve postoperative analgesia or characteristics of postoperative recovery in patients undergoing major abdominal surgery within an ERP pathway.

Abstract
OBJECTIVE The use of basic transesophageal echocardiography (TEE) in critically ill and older surgical patients can change patient management and improve outcomes after noncardiac surgery. The authors hypothesized that educating the future generation on basic TEE skills by an intense two-month rotation will help them achieve basic TEE certification by the National Board of Echocardiography (NBE) and facilitate good use of their skills for patient care during their practice. DESIGN This is a descriptive report of graduating anesthesiology residents who completed two months basic TEE rotation at the authors' residency program between 2013 and 2019. The authors report the clinical training goals, NBE testamur and certification status, and a survey report on the use of basic TEE skills in their practice SETTINGS: University medical center. PARTICIPANTS Residents who completed two months basic TEE rotation during their Clinical Anesthesia (CA)-3 year. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Of a total of 115 residents, 67 (58%) elected basic TEE rotation. The NBE basic TEE certification and testamur status were achieved by 12 (21%) and 14 (24%) eligible residents, respectively. Residents (n = 43) personally performed 73 ± 21 (mean ± standard deviation) and reviewed 72 ± 28 (mean ± standard deviation basic TEE studies before graduation. The survey indicated that 63.4% of residents trained in basic TEE did not use their skills in their practice. CONCLUSIONS Two months' basic TEE rotation was able to fulfill its educational goals (testamur status and clinical training) but fell short on achieving NBE certification rate and its ultimate impact on practice and patient care.

Targets for Intervention? Preoperative Predictors of Postoperative Ileus After Colorectal Surgery in an Enhanced Recovery Protocol. J Gastrointest Surg 2021; 25:2065-2075.

Abstract
BACKGROUND Postoperative ileus occurs in up to 30% of colorectal surgery patients and is associated with increased length of stay, costs, and morbidity. While Enhanced Recovery Protocols seek to accelerate postoperative recovery, data on modifiable preoperative factors associated with postoperative ileus in this setting are limited. We aimed to identify preoperative predictors of postoperative ileus following colorectal surgery in Enhanced Recovery Protocols, to determine new intervention targets. METHODS We performed a retrospective single-center cohort study of patients ≥ 18 years old who underwent colorectal surgery via Enhanced Recovery Protocols (7/2015-7/2017). Postoperative ileus was defined as nasogastric tube insertion postoperatively or nil-per-os by postoperative day 4. Preoperative risk factors including comorbidities and medication use were identified using multivariable stepwise logistic regression. RESULTS Of 530 patients, 14.9% developed postoperative ileus. On univariate analysis of perioperative and postoperative factors, postoperative ileus patients had increased psychiatric illness, antidepressant and antipsychotic use, American Society of Anesthesiologists classification, ileostomy creation, postoperative opioid use, complications, surgery duration, and length of stay (p < 0.05). Multivariable logistic regression model for preoperative factors identified psychiatric illness, preoperative antipsychotic use, and American Society of Anesthesiologists classification ≥ 3 as significant predictors of postoperative ileus (p < 0.05). DISCUSSION Postoperative ileus remains a common complication following colorectal surgery under Enhanced Recovery Protocols. Patients with pre-existing psychiatric comorbidities and preoperative antipsychotic use may be a previously overlooked cohort at increased risk for postoperative ileus. Additional research and preoperative interventions within Enhanced Recovery Protocols to reduce postoperative ileus for this higher-risk population are needed.

Abstract
BACKGROUND Bloodstream infection (BSI) is a major cause of morbidity and mortality. The classification of infection into community-acquired, hospital-acquired, and healthcare-associated infection provides an educated guess on the possible aetiological agents and appropriate empirical antimicrobial therapy to be instituted. This study aims to determine the aetiological agents, the antimicrobial susceptibility patterns, and the classification of infections among the paediatric population. MATERIALS & METHODS This study was conducted in Hospital Kuala Lumpur, Malaysia from January 2016 to December 2017. A total of 303 isolates were included in this study which was obtained from 238 patients. The patients' microbiological worksheets and medical notes were reviewed to determine the antimicrobial susceptibility patterns, demographic data, classification of infection, and outcome (survival versus death). RESULTS Most of the patients were in the age group of one to less than five years old (41%) with 58% male and 85% Malay patients. Common causes of BSI were Staphylococcus aureus (17%), followed by Klebsiella pneumoniae (15%), Acinetobacter baumanii (10%), Pseudomonas aeruginosa (10%), and Escherichia coli (6%). Sixty percent of BSI episodes were caused by gram-negative bacteria, 34% by gram-positive bacteria, and 6% by fungi. Most of the infections were classified as hospital-acquired infections (72%), followed by healthcareassociated (20%) and community-acquired infections (8%). There were 33% of methicillin-resistant Staphylococcus aureus, 53% of extended-spectrum beta-lactamase (ESBL) producing Klebsiella pneumoniae, and 33% ESBL producing Escherichia coli. The overall case fatality rate (CFR) was 27% with the highest CFR caused by Serratia marcescens (53.3%). CONCLUSIONS The majority of paediatric bloodstream infections are hospital-acquired. Improvement in prevention strategies and revisions in antibiotic policies are important to overcome it.

Abstract
Congenital hypothyroidism (CH) occurs due to thyroid dysgenesis, thyroid ectopy, and dyshormonogenesis. A proportion of CH is transient which might be due to iodine deficiency/excess or maternal antibody-mediated. Certain forms of dyshormonogenetic defects may cause transient hypothyroidism. Here is a report of a neonate with overt clinical and biochemical hypothyroidism, who on evaluation was found to have dyshormonogenesis with a homozygous mutation in dual oxidase 2 (DUOX2) gene. During infancy, she became euthyroid. Severe in utero deficiency of thyroid hormone, very short duration of hypothyroidism and first-reported mutation of the DUOX2 gene in the Indian subcontinent were interesting features in this infant.

Abstract
Cardiac surgeries are known to produce moderate to severe pain. Pain management has traditionally been based on intravenous opioids. Poorly controlled pain can result in increased incidence of respiratory complications such as atelectasis and pneumonia leading to prolonged intubation and intensive care unit length of stay and subsequent prolonged hospital stay. Adequate perioperative analgesia improves hemodynamics and immunologic responses, which would result in better outcomes after cardiac surgery. Opioid sparing "Enhanced Recovery After Surgery" protocols are increasingly being incorporated into cardiac surgeries. This will reduce opioid requirements and opioid-related side effects and facilitate fast-tracking of patients. Regional analgesia can be provided by neuraxial blocks, fascial plane blocks, peripheral nerve blocks, or simply by the infiltration of the wound with local anesthetics for cardiac surgery. Neuraxial analgesia is provided through epidural, spinal, and paravertebral routes. Though they are being replaced by peripheral fascial plane blocks, epidural and spinal analgesia are still being used in some centers. In this article, neuraxial forms of analgesia are focused. We sought to review epidural analgesia and its impact in suppressing hemodynamic stress response, reducing pulmonary complications, and development of chronic pain. The relationship between intraoperative heparinization and potential neuraxial hematoma is discussed. Other neuraxial options such as spinal and paravertebral analgesia and their usefulness, benefits, and limitations are also reviewed.

Abstract
Opioid analgesia is still considered the standard of practice for cardiac surgery. In recent years, combinations of several nonnarcotic analgesics and regional analgesia have shown promise in restricting opioid use during and after cardiac surgery. Ketamine infusion, dexmedetomidine infusion, acetaminophen, ketorolac, and gabapentin are useful adjuvants in cardiac anesthesia practice and have opioid-sparing properties. The beneficial effects of nonnarcotic multimodal analgesia on intraoperative stress response, recovery profile, postoperative pain, and persistent opioid use after cardiac surgery are yet to be established, and further randomized clinical trials are required.

Coronary heart disease (CHD) is the most important cause of cardiovascular death and when premature, it affects the most productive population of the community. Premature CHD usually has a specific etiology, which on diagnosis, might help in the secondary prevention in that individual. We report a case of young adult with recurrent myocardial infarction, who on evaluation had mildly reduced HDL and Protein C levels with elevated serum homocysteine. Clinical exome identified a possibly pathogenic variant of ABCA1 gene, associated with Tangier disease.

[PMID: 33215723 DOI: 10.1111/vox.13016] [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: 06/17/2020] [Revised: 09/18/2020] [Accepted: 09/21/2020] [Indexed: 12/22/2022]
Abstract
BACKGROUND Studies examining one-year mortality respecting component blood transfusion are sparse. We hypothesize that component blood product transfusions are negatively associated with 90-day and 1-year survival for all patients requiring veno-arterial (VA) or veno-venous (VV) ECMO. STUDY DESIGN AND METHODS This was an IRB-approved retrospective cohort analysis of 676 consecutive patients requiring ECMO at the University of Pittsburgh between 2005 and 2016. Patients were analysed both as an entire cohort and as two subsets with respect to ECMO modality (VA vs. VV). Additional data collected and analysed included patient characteristics, laboratory values and blood product transfusion. RESULTS Multivariable analysis revealed that platelet transfusion was associated with 90-day mortality (OR: 1·05, P = 0·037) and one-year mortality for the entire cohort (OR = 1·05, P = 0·046,). Platelet transfusion volume was also associated with mortality in the VA-ECMO subset of patients at both 90 days (OR = 1·08, P = 0·03) and one year (OR: 1·11, P = 0·014). Age, peak International Normalized Raton ECMO, nadir haemoglobin (on ECMO) and final haemoglobin (after ECMO) were significantly associated with mortality for patients requiring VA-ECMO. For VV-ECMO patients, age, INR and peak creatinine on ECMO were associated with mortality. No individual component blood product was associated with one-year mortality for patients requiring VV-ECMO. CONCLUSION Platelet transfusion was associated with increased 90-day and 1-year mortality for patients requiring VA-ECMO.

Abstract
OBJECTIVE(S) The objective of this study was to identify transfusion-related in-hospital outcomes in orthotopic heart transplantation (OHT) recipients. DESIGN Retrospective chart review. SETTING Tertiary care hospital. PARTICIPANTS Adult OHT recipients undergoing transplantation between January 2010 and December 2016. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS The primary composite outcome was occurrence of any of the following events during admission for OHT: (1) graft dysfunction requiring mechanical circulatory support (MCS); (2) respiratory failure requiring tracheostomy; (3) renal failure requiring hemodialysis; (4) 30-day mortality; (5) complication requiring readmission to intensive care unit; (6) sepsis; and (7) stroke. The authors evaluated these outcomes in relation to all blood component transfusions received intraoperatively and in the first 24 hours postoperatively. The study included 197 patients and the primary composite outcome was present in 72 (36.6%). After adjusting for propensity score, red blood cell (RBC) transfusion was associated with composite outcomes (odds ratio [OR] 1.17, 95% confidence interval [CI] 1.05-1.31, p = 0.004), postoperative MCS use (OR 1.36, 95% CI 1.18-1.58, p < 0.001), acute renal failure requiring hemodialysis (OR 1.21, 5% CI 1.06-1.38, p = 0.004), and 30-day mortality (OR 1.29, 95% CI 1.05-1.59, p = 0.02). Fresh frozen plasma was associated with composite outcome (OR 1.07, 95% CI [1.003-1.15], p = 0.042) and renal failure (OR 1.08, 95% CI 1.08 [1.002-1.17], p = 0.04). CONCLUSIONS Intra- and postoperative transfusions (first 24 hours) of RBC and FFP were associated with adverse postoperative composite outcomes in patients undergoing OHT.

Intraoperative Remifentanil Infusion and Postoperative Pain Outcomes After Cardiac Surgery-Results from Secondary Analysis of a Randomized, Open-Label Clinical Trial. J Cardiothorac Vasc Anesth 2020; 35:458-466. [PMID: 32962934 DOI: 10.1053/j.jvca.2020.08.064] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/13/2020] [Revised: 08/26/2020] [Accepted: 08/28/2020] [Indexed: 11/11/2022]
Abstract
DESIGN Report of secondary pain outcomes from a prospective, randomized, open-label clinical trial that compared remifentanil and fentanyl on perioperative hyperglycemic response in cardiac surgery. SETTING Single institution, tertiary university hospital. PARTICIPANTS The study comprised 116 adult elective cardiac surgical patients. INTERVENTIONS Participants were randomly assigned to receive either intermittent fentanyl boluses (F) or continuous remifentanil infusion (R) intraoperatively. MEASUREMENTS AND MAIN RESULTS Postoperative pain was evaluated with pain scores every 6 hours for 48 hours. Pain threshold to mechanical stimuli was measured around the sternotomy incision at 48 and 96 hours. The development of chronic pain was assessed using the numeric rating scale at 1, 3, 6, and 12 months after discharge. The final analysis included 106 patients. Pain scores and wound hyperalgesia were not significantly different postoperatively between the groups. The incidence of chronic pain at 3 months was comparable in both groups (61% in group F v 58% in group R; p = 0.79). Pain of more-than-mild degree was seen in 13 (32%) patients in group F and 8 (19%) in group R (p = 0.25) at 3 months. Median pain scores were not significantly different between the groups at 1, 3, 6, and 12 months after discharge from the hospital. CONCLUSIONS The present study's findings suggested that intraoperative remifentanil infusion does not significantly worsen pain outcomes in patients undergoing elective cardiac surgery.

Conferring root-knot nematode resistance via host-delivered RNAi-mediated silencing of four Mi-msp genes in Arabidopsis. PLANT SCIENCE : AN INTERNATIONAL JOURNAL OF EXPERIMENTAL PLANT BIOLOGY 2020; 298:110592. [PMID: 32771150 DOI: 10.1016/j.plantsci.2020.110592] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/10/2020] [Revised: 06/27/2020] [Accepted: 07/01/2020] [Indexed: 05/27/2023]
Abstract
The root-knot nematode (RKN) Meloidogyne incognita is considered one of the most damaging pests among phytonematodes. The majority of nematode oesophageal gland effector genes are indispensable in facilitating M. incognita parasitization of host plants. We report the effect of host-delivered RNAi (HD-RNAi) silencing of four selected M. incognita effector genes, namely, Mi-msp3, Mi-msp5, Mi-msp18 and Mi-msp24, in Arabidopsis thaliana. Mi-msp5, Mi-msp18 and Mi-msp24, which are dorsal gland genes, were found to be maximally expressed in the adult female stage, whereas Mi-msp3, which is a sub-ventral gland gene, was maximally expressed in an earlier stage. In transgenic plants expressing dsRNA, the reduction in the number of galls on roots was 89 %, 78 %, 86 % and 89 % for the Mi-msp3, Mi-msp5, Mi-msp18 and Mi-msp24 RNAi events, respectively. Moreover, gene transcript abundance was significantly reduced in RKN females feeding on dsRNA-expressing lines by up to 60 %, 84 %, 31 % and 61 % for Mi-msp3, Mi-msp5, Mi-msp18 and Mi-msp24, respectively. Furthermore, the M. incognita reproduction factor was reduced up to 71-, 344-, 107- and 114-fold in Arabidopsis plants expressing Mi-msp3, Mi-msp5, Mi-msp18 and Mi-msp24 dsRNA constructs, respectively. This study provides a set of potential target genes to curb nematode infestation in economically important crops via the HD-RNAi approach.

Safety and Benefit of Transesophageal Echocardiography in Liver Transplant Surgery: A Position Paper From the Society for the Advancement of Transplant Anesthesia (SATA). Liver Transpl 2020; 26:1019-1029. [PMID: 32427417 DOI: 10.1002/lt.25800] [Citation(s) in RCA: 33] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/12/2020] [Revised: 04/11/2020] [Accepted: 05/03/2020] [Indexed: 02/07/2023]
Abstract
More anesthesiologists are routinely using transesophageal echocardiography (TEE) during liver transplant surgery, but the effects on patient outcome are unknown. Transplant anesthesiologists are therefore uncertain if they should undergo additional training and adopt TEE. In response to these clinical questions, the Society for the Advancement of Transplant Anesthesia appointed experts in liver transplantation and who are certified in TEE to evaluate all available published evidence on the topic. The aim was to produce a summary with greater explanatory power than individual reports to guide transplant anesthesiologists in their decision to use TEE. An exhaustive search recovered 51 articles of uncontrolled clinical observations. Topics chosen for this study were effectiveness and safety because they were a major or minor topic in all articles. The pattern of clinical use was a common topic and was included to provide contextual information. Summarized observations showed effectiveness as the ability to make a new and unexpected diagnosis and to direct the choice of clinical management. These were reported in each stage of liver transplant surgery. There were observations that TEE facilitated rapid diagnosis of life-threatening conditions difficult to identify with other types of monitoring commonly used in the operating room. Real-time diagnosis by TEE images made anesthesiologists confident in their choice of interventions, especially those with a high risk of complications such as use of anticoagulants for intracardiac thrombosis. The summarized observations in this systematic review suggest that TEE is an effective form of monitoring with a safety profile similar to that in cardiac surgery patients.

Anesthetic management of lung transplantation: Results from a multicenter, cross-sectional survey by the society for advancement of transplant anesthesia. Clin Transplant 2020; 34:e13996. [PMID: 32484978 DOI: 10.1111/ctr.13996] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2019] [Revised: 04/27/2020] [Accepted: 05/22/2020] [Indexed: 12/24/2022]
Abstract
BACKGROUND Current protocols for the perioperative care of lung transplant (LTX) recipients lack rigorous evidence and are often empiric, based upon institutional preferences. We surveyed LTX anesthesiologists to determine the most common practices. METHODS We developed a survey of 40 questions regarding perioperative care of LTX recipients using Qualtrics software. The survey was sent out to members of the Society of Cardiovascular Anesthesiologists performing LTX at geographically diverse sites to facilitate data collection for as many practices as possible. RESULTS The responses were center-weighed (127 responses, 85% from academic settings). The clamshell approach was commonly used (70%). Cardiopulmonary bypass was preferred by 56%, ex vivo lung perfusion utilized by 43%, and 49.4% indicated they use lungs from donation after circulatory determination of death. Most (69%) used oximetric pulmonary artery catheters, 60% used tissue oximetry, and 89.3% utilized transesophageal echocardiography. Inhaled nitric oxide was preferred by 48%, restrictive fluid management by 48%, and systemic analgesia advocated by 49% of participants. Inspired oxygen concentration <30% was applied to the new lung on reperfusion by 28% of the respondents. CONCLUSION Variations in healthcare delivery and utilization for LTX recipients indicate gaps in knowledge and potential opportunities to improve the quality of care.

Perioperative Transthoracic Echocardiography Practice By Cardiac Anesthesiologists-Report of a "Start-Up" Experience. J Cardiothorac Vasc Anesth 2020; 35:222-232. [PMID: 32888802 DOI: 10.1053/j.jvca.2020.06.046] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/28/2020] [Revised: 06/10/2020] [Accepted: 06/12/2020] [Indexed: 01/09/2023]
Abstract
OBJECTIVE In this paper, the authors report their experience of perioperative transthoracic echocardiography (TTE) practice and its impact on perioperative patient management. DESIGN Retrospective case series. SETTING Single institution, tertiary university hospital. PARTICIPANTS A total of 101 adult ASA II-V male and female patients >18 years old who were scheduled for or having surgery were included in this retrospective case series. INTERVENTIONS All patients underwent a focused perioperative TTE exam performed by cardiac anesthesiologists with significant TTE experience, and further clinical management was based on echocardiography findings discussed with the anesthesia care team. MEASUREMENTS Significant echocardiographic findings and changes in patient management were reported. Step-up management was a new intervention that was executed based on echocardiographic findings (volume infusion, inotropic therapy, cardiology consultation, and other interventions), and step-down management was avoidance of an unnecessary intervention based on echocardiographic findings (proceeding to surgery without cancellation, delay, cardiology consultation, and additional investigations/interventions). MAIN RESULTS Fifty-three percent of TTEs were performed in the preoperative setting, 34% were intra-operative, and 13% were postoperative. No significant findings were detected in 38 patients, leading to step-down management in all of them. Among patients with positive findings, left ventricular dysfunction (12.8%), hypovolemia (10.8%), and right ventricular dysfunction (7.9%) were the most common. Step-up therapy included inotropic/vasopressor therapy (24.8%), intensive care admission after surgery for further management (13.8%), volume infusion (12.8%), and other interventions (additional monitoring, surgical delay, cardiology consultation, and modification of surgical technique). CONCLUSION Perioperative focused TTE examination is useful in the diagnosis of new cardiac conditions for anesthesia management (intraoperative monitoring and hemodynamic therapy) and postoperative care (intensive care unit admissions). Perioperative TTE performed by anesthesiologists can also help avoid procedural delays and unnecessary consults.

Sex Comparisons in Opioid Use and Pain After Colorectal Surgery Using Enhanced Recovery Protocols. J Surg Res 2020; 253:105-114.

Abstract
BACKGROUND Differences in nociception and use of opioids between sexes are of particular interest, considering higher rates of persistent opioid use among women after surgery. Although enhanced recovery protocols (ERPs) have improved postoperative pain control in colorectal surgery, sex-based comparisons of inpatient opioid use after surgery in an ERP remain understudied. METHODS This retrospective study analyzed data from adults after colorectal surgery using an ERP at a single hospital between 2015 and 2017. The main outcome was the rate of opioid consumption measured as oral morphine equivalents per inpatient day. Poisson regression determined association between sex and opioid consumption, accounting for early discharge, using inverse probability weighting and adjusting for covariates that retained significance on univariate analysis. Linear regression assessed the association between sex and pain scores on postoperative days 0-5 adjusting for covariates. RESULTS Of 588 patients included, 43% were men and 57% were women. In the unadjusted model, malignancy, prehospital psychiatric medication and analgesic use, tobacco, ileostomy creation, operative time, and postoperative complications were associated with increased opioid consumption. In multivariate analyses, prehospital opioid and nonopioid analgesic use, operative time, anastomotic leak, and postoperative ileus remained significantly associated with increased inpatient opioid consumption. However, there was no significant association between sex and opioid use in crude or adjusted analysis (incidence rate ratio: 1.09; 95% confidence interval: 0.90, 1.32). Women reported higher average daily pain scores (coefficient: 0.29; 95% confidence interval: 0.04, 0.55) in adjusted analyses. CONCLUSIONS Among patients undergoing colorectal surgery using an ERP, sex-based differences exist in pain scores but not early postoperative opioid consumption. Identification of intragroup differences in postoperative pain and opioid use among patients managed with an ERP serves as targets for customization and enhancement of current protocols. Furthermore, incongruence between reported pain and analgesic administration may have important implications for sex-related differences in persistent opioid use.

Abstract
End-stage lung disease is ultimately treated with lung transplantation. However, there is a paucity of organs with an increasing number of patients being diagnosed with end-stage lung disease. Ex vivo lung perfusion has emerged as a potential tool to assess the quality and to recondition marginal donor lungs prior to transplantation with the goal of increasing the donor pool. This technology has shown promise with similar results compared with the conventional technique of cold static preservation in terms of primary graft dysfunction and overall outcomes. This review provides an update on the results and uses of this technology. The review will also summarize clinical studies and techniques in reconditioning and assessing lungs on ex vivo lung perfusion. Last, we discuss how this technology can be applied to fields outside of transplantation such as thoracic oncology and bioengineering.
