Abstract:
e23319 Background: Current guidelines recommend transfusing at a hemoglobin (Hb) threshold of 7g/dl. There is a lack of evidence to support a specific threshold for transfusion in patients with active malignancy admitted to the Intensive Care Unit (ICU). This study attempts to determine an evidence-based threshold for blood transfusions in cancer. Methods: A retrospective study was done to study 561 patients with an active cancer diagnosis admitted to Northeast Georgia Medical Center ICU between 2017 and 2023 that received at least one unit of blood transfusion.

Abstract Background: Few studies have examined patients’ views, knowledge, and understanding of glycohemoglobin A1c (HbA1c) testing. We explored such issues in patients with type 1 diabetes and used their statements to estimate analytical quality specifications for HbA1c testing. Methods: We recruited 201 patients from a hospital outpatient clinic. A questionnaire was used to collect information on diabetes characteristics, perceived knowledge of HbA1c, last HbA1c value, HbA1c target value, and thresholds for action. Patients were asked to indicate the magnitude of change in HbA1c from 9.4% th

Abstract:
Cardiorespiratory performance is one of the most important determinants of success in sports activities. In order to better prepare for sports challenges, the athletes must be exposed to appropriate training which should be based on individualized physiological parameters during activity. Even though training intensity can be determined in many different ways, the endurance training intensity is often quantified by the lactate thresholds obtained from the blood sampling or the ventilator thresholds obtained from the gas exchange. These data represent delayed indirect indicators of an increased

Abstract:
OBJECT There is limited literature available to guide transfusion practices for patients with severe traumatic brain injury (TBI). Recent studies have shown that maintaining a higher hemoglobin threshold after severe TBI offers no clinical benefit. The present study aimed to determine if a higher transfusion threshold was independently associated with an increased risk of progressive hemorrhagic injury (PHI), thereby contributing to higher rates of morbidity and mortality.

Impact Statement: Patient blood management (PBM) recommendations can help providers manage anemia and assist in transfusion-related decision-making. Introduction: Blood transfusions are often a necessary treatment for operative patients, but they are not without potential complications, including hemolytic reactions, and even death. Establishing parameters and guidelines for transfusions in patients undergoing an operation is imperative in treating them safely and effectively; patient blood management protocols provide these guidelines.

Abstract:
Changes between pre- and postpartum hemoglobin might be useful for optimizing the postpartum diagnosis of postpartum hemorrhage (PPH), defined as a blood loss exceeding 500 mL. This study’s principal objective was to estimate the mean change in hemoglobin (between pre/post-delivery hemoglobin) among women with vaginal deliveries and PPH. The secondary objectives were to analyze: hemoglobin changes according to blood volume loss, the appropriateness of standard thresholds for assessing hemoglobin loss, and the intrinsic and extrinsic performances of these threshold values for identifying PPH.

Abstract:
The oral glucose tolerance test (OGTT) serves as a pivotal diagnostic tool and a measure of glucose metabolism dynamics in diabetes mellitus (DM). In clinical settings, the OGTT involves administering a standardized glucose solution to the patient after an overnight fast, followed by periodic measurements of blood glucose levels over several hours. This test is instrumental in diagnosing impaired glucose tolerance (IGT) and diabetes mellitus by evaluating how effectively the body processes glucose. Diagnostic thresholds are established based on plasma glucose levels measured at specific time p

Abstract:
This case focuses on red cell transfusions in critically ill patients by asking the question: When should patients in the intensive care unit (ICU) with anemia receive red cell transfusions? For most critically ill patients, waiting to transfuse red cells until the hemoglobin (Hgb) drops below 7 g/dL is at least as effective as, and likely preferable to, transfusing at an Hgb less than 10 g/dL. These findings may not apply to patients with chronic anemia, who were excluded from the trial. The results also may not apply to patients with active cardiac ischemia, who were poorly represented in th

Abstract:
Oxygen delivery in normal physiologic states is determined by cardiac output, hemoglobin, oxygen saturation, and to a lesser extent, dissolved oxygen in the blood. Compensatory mechanisms such as an increase in stroke volume, heart rate, and re-distribution of blood flow helps in scenarios with increased oxygen demand. In cases of acute hemodynamic decompensation, this pre-existing physiologic relation between oxygen delivery and oxygen consumption is altered, resulting in tissue hypoxia and resultant anaerobic metabolism. A persistent state of sub-critical O2 delivery correlates with increase

Abstract:
Sickle cell anemia is a blood disorder which is widespread across world with an estimate that about 30% of total population will be affected by the end of 2050. Especially in India, the frequency of sickle cell trait can reach up to 35%, thereby increasing attention over the topic for research. It is necessary to detect the disorder as much as it is for finding a cure to it. Therefore, a system that detect the sickle cells from the blood smear images or erythrocytes images is required.
