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 Adequate oxygen in red blood cells carrying through the body to the heart and brain is important to maintain life. For those patients requiring blood, blood transfusion is a common procedure in which donated blood or blood components are given through an intravenous line. However, detecting the need for blood transfusion is time-consuming and sometimes not easily diagnosed, such as internal bleeding. This study considered physiological signals such as electrocardiogram (ECG), photoplethysmogram (PPG), blood pressure, oxygen saturation (SpO2), and respiration, and proposed the machine learning model to detect the need for blood transfusion accurately.

Abstract The present paper proposes a novel system that automatically classifies the eight different blood groups according to the ABO and Rh blood group systems. The proposed system is developed by applying MATLAB’s image processing techniques on the blood sample images. These images are acquired from the laboratory using the slide test. It utilizes a mean filter for removing noise from blood sample images. In addition, the Contrast Limited Adaptive Histogram Equalization (CLAHE) is used for enhancing the image characteristics analysis. The proposed system also utilizes the automated threshold strategy (Otsu’s approach) for obtaining the blood… More >

Abstract Introduction: To assess 30-day morbidity and mortality following partial nephrectomy (PN) and radical nephrectomy (RN) with relation to the administration of perioperative blood transfusions (PBT).
Materials and methods: The National Surgical Quality Improvement Program was queried for patients with malignant renal tumors (International Classification of Diseases Ninth Revision codes 189-189.2) who underwent RN (Current Procedure Terminology codes 50220, 50225, 50230, 50234, 50236, 50545, 50546, 50548) or PN (50240, 50543) between 2005-2013. Patients were stratified by transfusion status and assessed for postoperative outcomes both separately and in composite, including morbidity, mortality, infectious complications, and pulmonary complications. Univariate and… More >

Abstract Introduction: Infectious complications are common after radical cystectomy (RC), and allogeneic blood transfusions may increase infection risk by an immunosuppressive effect. While it has been suggested that perioperative blood transfusion (PBT) may be associated with adverse oncologic outcomes after RC, no large analyses have assessed whether PBT increases the risk of perioperative infection after RC.
Materials and methods: We used the Nationwide Inpatient Sample (1998 to 2011) to study the rate of PBT during RC for bladder cancer and identify infectious complications. We compared rates of infectious complications in patients who did and did not receive PBT… More >

Abstract Introduction: Perioperative blood transfusion (PBT) has been shown to contribute to cancer progression and mortality. This study sought to determine the impact of PBT during radical cystectomy on cancer-specific survival (CSS) and overall survival (OS).
Materials and methods: The Columbia University Urologic Oncology Database was reviewed for patients who underwent a radical cystectomy (RC) from 1989 to 2010 (n = 638). PBT was defined as non-autologous packed red blood cells (PRBC) received during the same hospital stay as the radical cystectomy. Clinical and pathological variables were compared between the cohorts, and survival analysis was performed using the… More >
