Abstract
BACKGROUND Cardiopulmonary bypass (CPB) is associated with systemic inflammation, featuring increased levels of circulating pro-inflammatory cytokines. Intra-operative ultrafiltration extracts fluid and inflammatory factors potentially dampening inflammation-related organ dysfunction and enhancing post-operative recovery. This study aimed to define the impact of continuous subzero-balance ultrafiltration (SBUF) on circulating levels of major inflammatory mediators. METHODS Twenty pediatric patients undergoing cardiac surgery, CPB and SBUF were prospectively enrolled. Blood samples were collected prior to CPB initiation (Pre-CPB Plasma) and immediately before weaning off CPB (End-CPB Plasma). Ultrafiltrate effluent samples were also collected at the End-CPB time-point (End-CPB Effluent). The concentrations of thirty-nine inflammatory factors were assessed and sieving coefficients were calculated. RESULTS A profound increase in inflammatory cytokines and activated complement products were noted in plasma following CBP. Twenty-two inflammatory mediators were detected in the ultrafiltrate effluent. Novel mediators removed by ultrafiltration included cytokines IL1-Ra, IL-2, IL-12, IL-17A, IL-33, TRAIL, GM-CSF, ET-1, and the chemokines CCL2, CCL3, CCL4, CXCL1, CXCL2 and CXCL10. Mediator extraction by SBUF was significantly associated with molecular mass < 66 kDa (Chi2 statistic = 18.8, Chi2 with Yates' correction = 16.0, p < 0.0001). There was a moderate negative linear correlation between molecular mass and sieving coefficient (Spearman R = - 0.45 and p = 0.02). Notably, the anti-inflammatory cytokine IL-10 was not efficiently extracted by SBUF. CONCLUSIONS CPB is associated with a burden of circulating inflammatory mediators, and SBUF selectively extracts twenty of these pro-inflammatory factors while preserving the key anti-inflammatory regulator IL-10. Ultrafiltration could potentially function as an immunomodulatory therapy during pediatric cardiac surgery. Trial registration ClinicalTrials.gov, NCT05154864.

Abstract
Background Cardiac surgery with cardiopulmonary bypass is associated with systemic inflammation. Ultrafiltration used throughout the cardiopulmonary bypass time, continuously, is hypothesized to be an immunomodulatory therapy. Methods A systematic review and meta-analysis of randomized trials investigating continuous forms of ultrafiltration during adult cardiac surgery (CRD42020219309) was conducted and is reported following PRISMA guidelines. MEDLINE, Embase, CENTRAL, and Scopus were searched on November 3, 2021. The primary endpoint was operative mortality, and secondary outcomes included intensive care unit length of stay (ICU LOS), ventilation time, acute kidney injury or renal failure, and pneumonia. Each study was assessed for risk of bias using the Cochrane Risk-of Bias-Tool for Randomized Trials (RoB2) instrument. Outcomes were analyzed with inverse variance random-effects models and assessed for GRADE quality of evidence. Results Twelve randomized trials consisting of 989 adult patients undergoing coronary, valvular, or concomitant cardiac procedures were included. Compared to controls, patients receiving continuous ultrafiltration had no statistical difference in operative mortality; risk ratio of 0.32 (95% confidence interval [CI]: 0.10-1.03; P = 0.06). Reductions occurred in ICU LOS, by 7.01 hours (95% CI: 1.86-12.15; P = 0.008); ventilation time, by 2.11 hours (95% CI: 0.71-3.51; P = 0.003); and incidence of pneumonia, with a risk ratio of 0.33 (95% CI: 0.15-0.75; P = 0.008). There wasno difference in renal injury. The GRADE quality of evidence for these outcomes ranged from very low to low. Conclusions Continuous forms of ultrafiltration enhance recovery after adult cardiac surgery by reducing ICU LOS, ventilation time, and incidence of pneumonia. A multicentre randomized trial could confirm and generalize these findings.

Abstract
Background Our aim was to establish if presence of circulating tumor cells (CTCs) predicted worse outcome in patients with non-metastatic esophageal cancer undergoing tri-modality therapy. Methods We prospectively collected CTC data from patients with operable non-metastatic esophageal cancer from April 2009 to November 2016 enrolled in our QUINTETT esophageal cancer randomized trial (NCT00907543). Patients were randomized to receive either neoadjuvant cisplatin and 5-fluorouracil (5-FU) plus radiotherapy followed by surgical resection (Neoadjuvant) or adjuvant cisplatin, 5-FU, and epirubicin chemotherapy with concurrent extended volume radiotherapy following surgical resection (Adjuvant). CTCs were identified with the CellSearch® system before the initiation of any treatment (surgery or chemoradiotherapy) as well as at 6-, 12-, and 24-months post-treatment. The threshold for CTC positivity was one and the findings were correlated with patient prognosis. Results CTC data were available for 74 of 96 patients and identified in 27 patients (36.5%) at a median follow-up of 13.1months (interquartile range:6.8-24.1 months). Detection of CTCs at any follow-up visit was significantly predictive of worse disease-free survival (DFS;hazard ratio [HR]: 2.44; 95% confidence interval [CI]: 1.41-4.24; p=0.002), regional control (HR: 6.18; 95% CI: 1.18-32.35; p=0.031), distant control (HR: 2.93; 95% CI: 1.52-5.65;p=0.001) and overall survival (OS;HR: 2.02; 95% CI: 1.16-3.51; p=0.013). After adjusting for receiving neoadjuvant vs. adjuvant chemoradiotherapy, the presence of CTCs at any follow-up visit remained significantly predictive of worse OS ([HR]:2.02;95% [Cl]:1.16-3.51; p=0.013) and DFS (HR: 2.49;95% Cl: 1.43-4.33; p=0.001). Similarly, any observed increase in CTCs was significantly predictive of worse OS (HR: 3.14; 95% CI: 1.56-6.34; p=0.001) and DFS (HR: 3.34; 95% CI: 1.67-6.69; p<0.001). Conclusion The presence of CTCs in patients during follow-up after tri-modality therapy was associated with significantly poorer DFS and OS regardless of timing of chemoradiotherapy.

Abstract
Background We compared the health‐related quality of life (HRQOL) in patients undergoing trimodality therapy for resectable stage I‐III esophageal cancer. Methods A total of 96 patients were randomized to standard neoadjuvant cisplatin and 5‐fluorouracil chemotherapy plus radiotherapy (neoadjuvant) followed by surgical resection or adjuvant cisplatin, 5‐fluorouracil, and epirubicin chemotherapy with concurrent extended volume radiotherapy (adjuvant) following surgical resection. Results There was no significant difference in the functional assessment of cancer therapy‐esophageal (FACT‐E) total scores between arms at 1 year (p = 0.759) with 36% versus 41% (neoadjuvant vs. adjuvant), respectively, showing an increase of ≥15 points compared to pre‐treatment (p = 0.638). The HRQOL was significantly inferior at 2 months in the neoadjuvant arm for FACT‐E, European Organization for Research and Treatment of Cancer quality of life questionnaire (EORTC QLQ‐OG25), and EuroQol 5‐D‐3 L in the dysphagia, reflux, pain, taste, and coughing domains (p < 0.05). Half of patients were able to complete the prescribed neoadjuvant arm chemotherapy without modification compared to only 14% in the adjuvant arm (p < 0.001). Chemotherapy related adverse events of grade ≥2 occurred significantly more frequently in the neoadjuvant arm (100% vs. 69%, p < 0.001). Surgery related adverse events of grade ≥2 were similar in both arms (72% vs. 86%, p = 0.107). There were no 30‐day mortalities and 2% vs. 10% 90‐day mortalities (p = 0.204). There were no significant differences in either overall survival (OS) (5‐year: 35% vs. 32%, p = 0.409) or disease‐free survival (DFS) (5‐year: 31% vs. 30%, p = 0.710). Conclusion Trimodality therapy is challenging for patients with resectable esophageal cancer regardless of whether it is given before or after surgery. Newer and less toxic protocols are needed.

Abstract
BACKGROUND Cardiac surgery with cardiopulmonary bypass (CPB) is associated with a systemic inflammatory syndrome that adversely impacts cardiopulmonary function and can contribute to prolonged postoperative recovery. Intra-operative ultrafiltration during CPB is a strategy developed by pediatric cardiac specialists, aiming to dampen the inflammatory syndrome by removing circulating cytokines and improving coagulation profiles during the cardiac operation. Although ultrafiltration is commonly used in the pediatric population, it is not routinely used in the adult population. This study aims to evaluate if randomized evidence supports the use of continuous intra-operative ultrafiltration to enhance recovery for adults undergoing cardiac surgery with CPB. METHODS This systematic review and meta-analysis will include randomized controlled trials (RCT) that feature continuous forms of ultrafiltration during adult cardiac surgery with CPB, specifically assessing for benefit in mortality rates, invasive ventilation time and intensive care unit length of stay (ICU LOS). Relevant RCTs will be retrieved from databases, including MEDLINE, Embase, CENTRAL and Scopus, by a pre-defined search strategy. Search results will be screened for inclusion and exclusion criteria by two independent persons with consensus. Selected RCTs will have study demographics and outcome data extracted by two independent persons and transferred into RevMan. Risk of bias will be independently assessed by the Revised Cochrane Risk-of-Bias (RoB2) tool and studies rated as low-, some-, or high- risk of bias. Meta-analyses will compare the intervention of continuous ultrafiltration against comparators in terms of mortality, ventilation time, ICU LOS, and renal failure. Heterogeneity will be measured by the χ2 test and described by the I2 statistic. A sensitivity analysis will be completed by excluding included studies judged to have a high risk of bias. Summary of findings and certainty of the evidence, determined by the GRADE approach, will display the analysis findings. DISCUSSION The findings of this systematic review and meta-analysis will summarize the evidence to date of continuous forms of ultrafiltration in adult cardiac surgery with CPB, to both inform adult cardiac specialists about this technique and identify critical questions for future research in this subject area. SYSTEMATIC REVIEW REGISTRATION This systematic review and meta-analysis is registered in PROSPERO CRD42020219309 ( https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42020219309 ).

Abstract
The use of cardiopulmonary bypass (CPB) can be associated with significant hemodilution, coagulopathy and a systemic inflammatory response for infants and children undergoing cardiac surgery. Intra-operative ultrafiltration has been used for decades to ameliorate these harmful effects. The novel combination of a continuous and non-continuous form of ultrafiltration, Subzero Balance Simple Modified Ultrafiltration (SBUF-SMUF) here described, seeks to enhance recovery from pediatric cardiac surgery and CPB.

Abstract
BACKGROUND AND AIM The P2Y12 platelet receptor inhibitor ticagrelor is widely used in patients following acute coronary syndromes or in those who have received coronary stents. Bentracimab is a monoclonal antibody-based reversal agent that is being formally evaluated in a Phase 3 clinical trial. Here, we probe the knowledge, attitudes, and practice patterns of cardiac surgeons regarding their perioperative management of ticagrelor and potential application of a ticagrelor reversal agent. METHODS A questionnaire was developed by a working group of cardiac surgeons to inquire into participants' practices and beliefs regarding ticagrelor and disseminated to practicing, Canadian-trained cardiac surgeons. RESULTS A total of 70 Canadian-trained cardiac surgeons participated. Bleeding risk was identified as the most significant consideration when surgically revascularizing ticagrelor-treated patients (90%). There is variability in the duration of withholding ticagrelor before coronary artery bypass graft procedure in a stable patient; 44.3% wait 3 days and 32.9% wait 4 days or longer. Currently, 15.7% of cardiac surgeons prophylactically give platelet transfusions and fresh frozen plasma intraoperatively following protamine infusion in patients who have recently received ticagrelor. Interestingly, 47.1% of surveyed surgeons were aware of a reversal agent for ticagrelor, 91.4% of cardiac surgeons would consider utilizing a ticagrelor reversal agent if available, and 51.4% acknowledged that the introduction of such an agent would be a major advance in clinical practice. CONCLUSIONS The present survey identified ticagrelor-related bleeding as a major concern for cardiac surgeons. Surgeons recognized the significant unmet need that a ticagrelor reversal agent would address.

Abstract
Fetal compressive intrapericardial teratoma is a rare and life-threatening condition, qualifying as a high-acuity low-occurrence (HALO) event. To prepare for delivery and immediate neonatal management, specialists from pediatric cardiology, cardiac surgery, maternal-fetal-medicine, neonatology, cardiac anesthesia, critical care, clinical perfusion, obstetrical nursing, and operating room nursing convened. An in situ operating room simulation was used to identify and introduce key team members, derive and practice the anticipated clinical management algorithm, position human and equipment resources strategically, and ensure that each specialist team was familiar with the environment and available equipment. As rehearsed in the simulation, the cesarean delivery of the patient and neonatal cardiac surgery was uncomplicated and yielded a favourable clinical outcome. A patient-specific HALO simulation preparation (PSHSP) can facilitate positive clinical outcomes and improve health care team confidence in HALO scenarios such as the birth of newborns anticipated to have cardiorespiratory instabilty.

The objective of this survey was to identify the beliefs and practice patterns of Canadian cardiac surgeons regarding surgical management of IDU-IE. METHODS A 30-question survey was developed by a working group and distributed to all practicing adult cardiac surgeons in Canada. Data were analyzed using descriptive statistics. RESULTS Of 146 surgeons, 94 completed the survey (64%). Half of surgeons (49%) would be less likely to operate on patients with IE if associated with IDU. In the case of prosthetic valve IE owing to continued IDU, 36% were willing to reoperate once and 14% were willing to reoperate twice or more. Most surgeons required commitments from patients before surgery (73%), and most referred patients to addiction services (81%). Some surgeons would offer a Ross procedure (10%) or homograft (8%) for aortic valve IE, and 47% would consider temporary mechanical circulatory support. Whereas only 17% of surgeons worked at an institution with an endocarditis team, 71% agreed that there was a need for one at each institution. Most surgeons supported the development of IDU-IE-specific guidelines (80%). CONCLUSIONS Practice patterns and surgical management of IDU-IE vary considerably across Canada. Areas of clinical unmet needs include the development of a formal addiction services referral protocol for patients, the development of an interdisciplinary endocarditis team, as well as the creation of IDU-IE clinical practice guidelines.

Abstract
Introduction: The use of cardiopulmonary bypass in pediatric cardiac surgery is associated with significant inflammation, fluid overload, and end-organ dysfunction yielding morbidity and mortality. For decades, various intraoperative ultrafiltration techniques such as conventional ultrafiltration, modified ultrafiltration (MUF), zero-balance ultrafiltration (ZBUF), and combination techniques (ZBUF-MUF) have been used to mitigate these toxicities and promote improved postoperative outcomes. However, there is currently no consensus on the ultrafiltration technique or strategy that yields the most benefit for infants and children undergoing open heart surgery. Methods: A librarian-conducted PubMed literature search from 1990 to 2018 yielded 90 clinical studies or publications on the various forms of ultrafiltration and the impact on physiologic markers and clinical outcomes. All publications were reviewed, summarized, and conclusions synthesized. The data sets were not combined for systematic or meta-analysis due to significant heterogeneity in study protocols and patient populations. Results: Modified ultrafiltration significantly promotes improved myocardial function, reduction in fluid overload, and reduced bleeding and transfusion complications. Furthermore, ZBUF has shown a consistent reduction in inflammatory cytokines and improved pulmonary function and compliance. There is conflicting evidence that MUF, ZBUF, and ZBUF-MUF culminate in reduced ventilation time and intensive care unit stay. Conclusion: Various modes of ultrafiltration have been shown to be associated with improved physiologic function or clinical outcomes in pediatric cardiac surgery. There are some inconsistent trial results that can be explained by heterogeneity in ultrafiltration, clinical staff preferences, and institution protocols. Ultrafiltration has some essential benefit as it is ubiquitously used at pediatric heart centers; however, the optimal protocol could be yet identified.

Abstract
4052 Background: We compared the health-related quality-of-life (HRQOL) of standard neoadjuvant cisplatin and 5-FU chemotherapy plus radiotherapy (N) followed by surgical resection to adjuvant cisplatin, 5-FU, and epirubicin chemotherapy with concurrent extended volume radiotherapy (A) following surgical resection for resectable esophageal carcinoma. Methods: 96 patients with stage I to III resectable cancer of the esophagus were enrolled into a prospective randomized trial (NCT00907543) from April 2009 to November 2016. Patients were randomized into 2 groups: N (47 cases) and A (49 cases). The primary end point was HRQOL using the FACT-E at one year. The secondary endpoints included other HRQOL measures, overall survival (OS), disease-free survival (DFS), and adverse events. Results: The median follow-up was 5.0 years [95% CI :4.6 to 5.5]. The majority of patients had adenocarcinomas of the distal esophagus/gastroesophageal junction (80.9% vs 87.8%). The stage distribution was: I 9%; II 22%; III 58%; TxN0-1 10%. Using an intention-to-treat analysis there was no significant difference in the FACT-E total scores between arms at one year (p = 0.759), with 35.5% vs. 41.2% respectively showing an increase of ≥ 15 points ( a priori minimal clinical difference) compared to pre-treatment (p = 0.638). The HRQOL was temporarily significantly inferior at 2 months in the N arm for FACT-E, EORTC OG25, and EQ-5D-3L in the dysphagia, reflux, pain, taste, and coughing domains (p < 0.05). There were no 30-day mortalities but 2.1% vs. 10.2% 90-day mortalities (p = 0.204). There were no significant differences in either 5-year OS (37.9% vs 28.9%, p = 0.321) or DFS (34.0% vs 25.5%, p = 0.551. 48.9% of patients required chemotherapy to be modified or stopped in the N arm compared to 57.1% in the A arm (p = 0.421). 51.1% of patients were able to complete the prescribed N arm chemotherapy without modification compared to only 14.3% in the A arm (p < 0.001). Chemotherapy related adverse events significantly more frequent in the neoadjuvant arm (p < 0.05). Surgery related adverse events were significantly more frequent in the neoadjuvant arm (p < 0.05). Conclusions: Trimodality therapy is challenging for patients with resectable esophageal cancer regardless if it is given before or after surgery. Less toxic protocols are needed. Clinical trial information: 00907543.

Abstract
In no other branch of medicine have doctors appeared so nihilistic or so defeatist as in the domain of psychiatry. It seems to me questionable whether this is due to the disparity in the therapeutic results between psychiatry on the one hand and general medicine on the other. In general medicine it is frequently forgotten that the really specific remedies at our disposal are so few that they can be counted on the fingers of one hand. If, on the other hand, we remember that as late as the time of the French Revolution mental patients were kept in chains, and that to-day in modern hospitals we see impressive results with such specific treatments as malarial therapy, then it must be admitted that the psychiatrist is not the only nihilist; but that this also applies to representatives of other branches of general medicine.

Abstract
Background: We present a rare complication of bilateral caudate infarcts and necrosed nasoseptal flaps after endoscopic transsphenoidal resection of tuberculum sellae meningioma. This case highlights the importance of early and accurate diagnosis and treatment of a postoperative cerebrospinal fluid (CSF) leak and associated bacterial meningitis, and reviews any existing guidelines regarding its management. Case Description: A 54-year-old otherwise healthy man presented with progressive bitemporal hemianopsia. Magnetic resonance imaging of the head revealed a large, homogeneously enhancing sellar and suprasellar mass consistent with a meningioma. An endoscopic endonasal transsphenoidal approach was performed to resect the tuberculum sellae meningioma. The patient developed basal bacterial meningitis secondary to a CSF leak, requiring repair on two separate occasions. At the time of both repairs, there was evidence of necrosis of the nasoseptal flaps used for the repairs. Soon after the diagnosis of meningitis, the patient developed bilateral caudate infarcts. Conclusion: This report discusses the possible underlying etiologies for the bilateral caudate infarcts and necrosed flaps including bacterial meningitis with associated local vasospasm of nearby vessels resulting in infarction. This case emphasizes the importance of concise management of postendoscopic CSF leak and discusses the guidelines regarding antimicrobial therapy and the management of lumbar drains.

Abstract
OBJECTIVE Endoscopic resection of pituitary adenomas has been reported to improve vision function in up to 80%-90% of patients with visual impairment due to these adenomas. It is unclear how these reported rates translate into improvement in visual outcomes and general health as perceived by the patients. The authors evaluated self-assessed health-related quality of life (HR-QOL) and vision-related QOL (VR-QOL) in patients before and after endoscopic resection of pituitary adenomas. METHODS The authors prospectively collected data from 50 patients who underwent endoscopic resection of pituitary adenomas. This cohort included 32 patients (64%) with visual impairment preoperatively. Twenty-seven patients (54%) had pituitary dysfunction, including 17 (34%) with hormone-producing tumors. Patients completed the National Eye Institute Visual Functioning Questionnaire and the 36-Item Short Form Health Survey preoperatively and 6 weeks and 6 months after surgery. RESULTS Patients with preoperative visual impairment reported a significant impact of this condition on VR-QOL preoperatively, including general vision, near activities, and peripheral vision; they also noted vision-specific impacts on mental health, role difficulties, dependency, and driving. After endoscopic resection of adenomas, patients reported improvement across all these categories 6 weeks postoperatively, and this improvement was maintained by 6 months postoperatively. Patients with preoperative pituitary dysfunction, including hormone-producing tumors, perceived their general health and physical function as poorer, with some of these patients reporting improvement in perceived general health after the endoscopic surgery. All patients noted that their ability to work or perform activities of daily living was transiently reduced 6 weeks postoperatively, followed by significant improvement by 6 months after the surgery. CONCLUSIONS Both VR-QOL and patient's perceptions of their ability to do work and perform other daily activities as a result of their physical health significantly improved by 6 months after endoscopic resection of pituitary adenoma. The use of multidimensional QOL questionnaires provides a precise assessment of perceived outcomes after endoscopic surgery.

Abstract
A BIGAMIST is a man who is "legally" married to two women. A "TRIGAMIST" (according to my definition) is a PERSON who is "married" (in the sense of being deeply attached) three times over to such an extent that there is little or no room left for a "permanent" commitment. The three "marriages" are to: a) a parent b) an occupation c) an ideal figure which exists only in the mind of the beholder. Parts of this syndrome have been described separately in scientific and literary form innumerable times but the syndrome as a WHOLE has never been recognised or described in spite of the fact that it is responsible for influencing millions of human relationships and destroying the life of countless people.
