Exploration of rotational thromboelastometry (ROTEM) to characterize the coagulation profiles of newly diagnosed pediatric leukemia patients.

Background: Viscoelastic testing has been used in adult hematologic malignancies in conjunction with conventional coagulation tests (CCTs) to predict coagulopathies and tailor blood product replacement. However, there is a paucity of similar pediatric studies.

Objectives: Analyze and correlate leukemia-associated coagulopathy in newly diagnosed pediatric leukemia patients using CCT's and Rotational Thromboelastometry (ROTEM).

Increased frequency of false-positive bacterial detection after implementation of new guidelines for large-volume delayed sampling of platelets.

Background: The updated guidance for improving bacterial detection (BD) of platelets has included the implementation of large-volume delayed sampling (LVDS) with the addition of anaerobic culture bottles (BPNs) and sampling of each platelet split product.

Methods: The frequency of BD was reviewed during this LVDS time period in comparison with pre-LVDS and the Post-Approval Surveillance Study of Platelet Outcomes, Release Tested (PASSPORT) study (when BPNs were last used).

Results: There was more than a twofold increase in bottles inoculated per collection during LVDS, with an almost fivefold increase in sample volume collected.

Prolonged prothrombin time does not correlate with clinical bleeding symptoms in newly diagnosed paediatric leukaemia patients.

Prolonged prothrombin time (PT) and/or activated partial thromboplastin time (aPTT) are frequently seen in newly diagnosed paediatric leukaemia patients (NDPLP), which can lead to delayed diagnostic and therapeutic procedures due to concern for bleeding. A single-centre retrospective chart review of NDPLP between 2015 and 2018 aged 1-21 years. We analysed 93 NDPLP of whom 33.

Direct oral anticoagulants in pediatric venous thromboembolism: Review of approved products rivaroxaban and dabigatran.

Venous thromboembolism is a major hospital acquired complication in the pediatric population over the last two-decades, with a 130% increase in the past decade. Direct oral anticoagulants (DOACs) are a newer class of anticoagulant medication for the treatment and prophylaxis of VTEs that provide the primary advantages of an oral route of administration without a requirement to adjust dosing to achieve a therapeutic level. It is anticipated that these medications will quickly replace parenteral anticoagulants and clinicians should familiarize themselves with DOACs.

Hemophagocytic Lymphohistiocytosis Gene Variants in Multisystem Inflammatory Syndrome in Children.

Multisystem inflammatory syndrome in children (MIS-C) affects few children previously infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). In 2020, 45 children admitted to our hospital for MIS-C underwent genetic screening with a commercial 109-immune-gene panel. Thirty-nine children were diagnosed with MIS-C, and 25.

The safety of COVID-19 convalescent plasma donation: A multi-institutional donor hemovigilance study.

Background: Although the safety and therapeutic efficacy of COVID-19 convalescent plasma (CCP) has been extensively evaluated, the safety of CCP donation has not been explored in a multi-institutional context.

Study Design And Methods: Nine blood collection organizations (BCOs) participated in a multi-institutional donor hemovigilance effort to assess the safety of CCP donation. Donor adverse events (DAEs) were defined according to the Standard for Surveillance of Complications Related to Blood Donation, and severity was assessed using the severity grading tool.

Multisystem inflammatory syndrome in children (MIS-C) and the prothrombotic state: Coagulation profiles and rotational thromboelastometry in a MIS-C cohort.

Background: Adults infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have had high rates of thrombosis. A novel condition in children infected with SARS-CoV-2, multisystem inflammatory syndrome in children (MIS-C), has limited data on their prothrombotic state or need for thromboprophylaxis.

Objectives: We aimed to analyze the prothrombotic state using coagulation profiles, rotational thromboelastometry (ROTEM) parameters and clinical outcomes, to determine if this could aid in risk stratification for thromboprophylaxis.

Are children with SARS-CoV-2 infection at high risk for thrombosis? Viscoelastic testing and coagulation profiles in a case series of pediatric patients.

The coagulopathy of the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is well documented in adults, with increases in D-dimer and prothrombin time found to be strong predictors of mortality, and anticoagulation shown to decrease this mortality. Viscoelastic parameters such as elevations in maximum clot firmness (MCF) on rotational thromboelastometry (ROTEM) have correlated with a hypercoagulable state in adults with SARS-CoV-2. We report our experience in children infected with SARS-CoV-2, with noted elevations in D-dimer and MCF on ROTEM (indicating hypercoagulability).

Mental health issues among migrant workers in Gulf Cooperation Council countries: literature review and case illustrations.

More than 15 million non-nationals are currently living and working in Gulf Cooperation Council (GCC) states. The majority are blue-collar or domestic workers coming from the Indian Subcontinent or South East Asia. They often work under very harsh conditions.
