    Abstract Background: To investigate the impact of preoperative extracorporeal membrane oxygenation (ECMO) on clinical outcomes in pediatric heart transplantation (PHT). Methods: This retrospective cohort analysis was conducted on 19 pediatric heart transplant recipients, divided into two groups: ECMO and non-ECMO, based on whether preoperative ECMO was utilized. We evaluated the patients’ surgical conditions, postoperative complications, and survival rates. Additionally, the analysis focused on the differences and correlations in clinical characteristics, inflammatory markers, and long-term survival outcomes. Results: There was no statistically significant difference in perioperative survival rates between the ECMO group (85.7%) and the non-ECMO group (83.3%). However,… More >

    Immune landscape of neoadjuvant chemoradiotherapy: involvement of MAL, a T-cell differentiation protein

    KOSEI NAKAJIMA1,2,3,*, YOSHINORI INO1

    Oncology Research, Vol.33, No.7, pp. 1769-1779, 2025, DOI:10.32604/or.2025.063419 - 26 June 2025

    Abstract Background: Neoadjuvant/preoperative therapy (NAT) involves the administration of chemotherapy, with or without radiation, prior to surgical resection. This approach is commonly used for locally advanced tumors to reduce tumor volume, improve resectability, and minimize the need for extensive surgical procedures. While NAT has been shown to be effective in inducing local anti-tumor immunity in potentially resectable solid tumors, the underlying molecular mechanisms remain poorly understood. Methods: Cohort samples from pancreatic cancer patients who underwent NAT (n = 26) and those who did not (n = 20) were analyzed. Changes in the immune microenvironment induced by… More >

    Muqsit Buchh1, Courtney Yong2, Fezaan Kazi1, Ali Sualeh1, James Slaven3, Ronald S. Boris2, Chandru P. Sundaram2

    Canadian Journal of Urology, Vol.31, No.2, pp. 11834-11839, 2024

    Abstract Introduction: Studies have reached mixed conclusions on the role of antiplatelet and anticoagulant agents on postoperative complications of partial nephrectomies. This study examines whether preoperative anticoagulation use affected the risk of hemorrhagic complications after partial nephrectomy.
    Materials and methods: This is a retrospective chart review of all partial nephrectomies performed between 2017 and 2022 at a single institution. For each operation, preoperative data was gathered on whether the patient was on anticoagulation, the type and dose of anticoagulation, and how many days the anticoagulation was held preoperatively. Bivariate analyses for continuous measures were performed using Student’s t-tests… More >

    Abstract Background: The pTNM staging system is widely recognized as the most effective prognostic indicator for cancer. The latest update of this staging system introduced a new pathological staging system (ypTNM) for patients receiving neoadjuvant chemoradiotherapy (NACRT). However, whether the prognostic value of the ypTNM staging system for rectal cancer is similar to that of the pTNM staging system remains unclear. This study was conducted to compare the ypTNM and pTNM staging systems in terms of their prognostic value for patients with nonmetastatic rectal cancer undergoing proctectomy. Material and Methods: This study was conducted at a large teaching… More >

    Preoperative Fasting of More Than 14 Hours Increases the Risk of Time-to-Death after Cardiothoracic Surgery in Children: A Retrospective Cohort Study

    Laortip Rattanapittayaporn, Maliwan Oofuvong*, Jutarat Tanasansuttiporn, Thavat Chanchayanon

    Congenital Heart Disease, Vol.18, No.1, pp. 23-39, 2023, DOI:10.32604/chd.2023.026026 - 09 January 2023

    Abstract Background: Prolonged preoperative fasting can cause hypoglycemia, hyperglycemia, and intravascular volume depletion in children. We aimed to examine whether prolonged preoperative fasting is associated with in-hospital mortality and other morbidities in pediatric cardiothoracic surgery. Methods: This retrospective cohort study included children aged 0–3 years who underwent cardiac surgery between July 2014 and October 2020. The patient demographic data, surgery-related and anesthesia-related factors, and postoperative outcomes, including hypoglycemia, hyperglycemia, sepsis, length of intensive care unit stay, and in-hospital mortality, were recorded. The main exposure and outcome variables were prolonged fasting and time-to-death after surgery, respectively. The associations between… More > Graphic Abstract

    Preoperative Feeding in Single Ventricle Neonates is Predictive of Shorter Time to Goal Feed

    Alyssia Venna1, Kathleen Reid2, Sarah Davis2, Jiaxiang Gai3, Yves d’Udekem1, Sarah Clauss2,*

    Congenital Heart Disease, Vol.17, No.5, pp. 505-518, 2022, DOI:10.32604/chd.2022.021571 - 06 September 2022

    Abstract Background: Patients with single ventricle anatomy are at increased risk of growth failure and malnutrition. Amongst cardiac centers, there is little standardization of feeding practices in this complex population. We hypothesized that initiation of our center’s preoperative feeding protocol would result in decreased gastrostomy tube (G-tube) use, decreased length of stay and would not result in increased Necrotizing Enterocolitis (NEC) rates. Methods: A single institution review of 52 patients who had undergone stage I single ventricle palliative repair was performed. Patient diagnoses were hypoplastic left heart syndrome (39%), atrioventricular canal (15%), and other (46%). Postoperative parameters such… More > Graphic Abstract

    Gregory P. Murphy1, Kushan D. Radadia1, Jonathan Weese1, Cooper R. Benson2, Niraj Badhiwala1, Alethea Paradis1, Joel Vetter1, Steven B. Brandes2

    Canadian Journal of Urology, Vol.27, No.3, pp. 10228-10232, 2020

    Abstract Introduction: To evaluate flexible pediatric cystoscopy (FPC) as an adjunctive procedure to retrograde urethrography (RUG) and voiding cystourethrography (VCUG) in the preoperative setting for male urethral strictures. Since imaging interpretation of stricture length and caliber can be difficult at times, we sought to evaluate diagnostic utility of FPC to predict reconstructive surgery.
    Materials and methods: Reconstructive urology databases at Washington University and Columbia University were queried from 2010-2017. A total of 185 anterior urethroplasty patients met inclusion criteria. All surgeries were performed by a single surgeon. There were 102 patients that underwent preoperative FPC (7.5 Fr in… More >

    Preoperative Risk Assessment and Perioperative Management of Adults with Congenital Heart Disease Undergoing Non-Cardiac Surgery

    Michela Palma, Giancarlo Scognamiglio*, Flavia Fusco, Assunta Merola, Anna Correra, Diego Colonna, Emanuele Romeo, Berardo Sarubbi

    Congenital Heart Disease, Vol.15, No.1, pp. 33-49, 2020, DOI:10.32604/CHD.2020.011523 - 17 June 2020

    Abstract Adults with congenital heart disease (ACHD) constitute a growing population with complex cardiac physiopathology and frequent extra-cardiac involvement. The recent dramatic improvement of their life expectancy has resulted in an increasing proportion of ACHD patients requiring non-cardiac surgery. While a large body of evidence demonstrated the importance of an accurate risk assessment in patients with acquired heart disease before noncardiac surgery in order to reduce perioperative morbidity and mortality and detailed algorithms have been released by international societies, no specific guidelines are available for the perioperative management in this population. Nonetheless, understanding the complex anatomy… More >
