BACKGROUND: Sickle cell disease (SCD) is a devastating, multisystemic disorder that affects millions of people worldwide. The earliest clinical manifestations of SCD can affect infants as young as 6 months of age, and pediatric patients are at risk for acute and life-threatening complications. Early intervention with treatments that target the underlying pathophysiological mechanism of SCD, sickle hemoglobin (HbS) polymerization, are expected to slow disease progression and circumvent disease-associated morbidity and mortality.
PROCEDURE: The HOPE-KIDS 1 trial (NCT02850406) is an ongoing four-part, phase 2a, open-label, single- and multiple-dose study to evaluate the pharmacokinetics, efficacy, and safety of voxelotor-a first-in-class HbS polymerization ...

Cancer patients are at a higher risk of complications such as venous thromboembolism (VTE). This risk increases in patients who receive chemotherapy. Despite the increased risk, common locations for VTE are similar to those in patients without cancer. Chemotherapy-port-related thrombosis represents a rare complication due to the location and frequent use of access (with Heparin flushes) as part of the standard care. Attention should be made to this rare complication, which may progress to superior vena cava (SVC) syndrome. SVC syndrome typically presents in females around the age of 57 years old. Management of this syndrome can be difficult and ...

The first descriptions of haemophilia A were reported in the second century AD, with the first modern description by John Conrad Otto in 1803. Historically, the natural history of haemophilia A was associated with very high rates morbidity and mortality, often following trivial accidents. Although treatment options for haemophilia A have been revolutionised in recent decades, haemophilia A remains a hereditary disease of concern and factor replacement products remain the mainstay of treatment.
As such, patients with haemophilia can carry huge burdens, particularly when a complication such as a FVIII inhibitor is present. A recently approved novel therapeutic, Emicizumab-kxwh, has ...

IgM multiple myeloma is a rare disease that shares many common features with Waldenström macroglobulinemia and lymphoplasmacytic lymphoma. It has been described in the literature as having unique diagnostic findings that separate it from the more common IgG and IgA myelomas. It is important for physicians to be able to differentiate between IgM multiple myeloma, Waldenström macroglobulinemia and lymphoplasmacytic lymphoma as their treatments vastly differ. This case report describes the clinical presentation of a patient with IgM lambda multiple myeloma and highlights the pathologic and clinical findings that are specific to this rare entity. We aim to provide further evidence ...

It is also essential to identify novel causative genetic variants of bone marrow failure to direct treatment in these patients.
Objectives: To describe the diagnosis and management of siblings who presented two weeks apart with severe pancytopenia and were diagnosed with severe aplastic anemia.
Methods: The first patient is a 13-year-old non-binary female who presented with severe pancytopenia on routine labs. Bone marrow biopsy revealed marked hypocellularity (0-10%) with hypoplasia. The second ...
Primary Venous Thromboprophylaxis In Pediatric Oncology Patients, 2022 Children's Mercy Hospital
Primary Venous Thromboprophylaxis In Pediatric Oncology Patients, Kyra Mccarty
Background: The Virchow’s Triad principles of venous stasis, endothelial damage, and hypercoagulability are all features of malignancy and contribute to the increased risk venous thromboembolism (VTE) seen in oncology patients. Additionally, certain chemotherapy treatments, presence of a central venous catheter and immobility are also intrinsically associated with malignancy diagnoses and exacerbate this risk. However, much debate exists over the use of thromboprophylaxis in the pediatric population, primarily due to lack of evidence regarding safety and efficacy, primarily the risk of major bleeding. Multiple retrospective studies have attempted to identify the primary risk factors for VTE in this pediatric oncology ...
A Novel Approach To Triosephosphate Isomerase Deficiency, 2022 Children's Mercy Hospital
A Novel Approach To Triosephosphate Isomerase Deficiency, Kyra Mccarty
Background: Triosephosphate isomerase deficiency (TPID) is a glycolytic pathway enzymopathy causing hemolytic anemia and neurologic dysfunction. TPID is caused by mutations in the TPI1 gene. These patients experience severe hemolytic anemia in infancy followed by progressive neurodegeneration. Diagnosis of TPID is made by measuring decreased TPI enzyme activity elevated dihydroxyacetone phosphate (DHAP) levels in the blood. The diagnosis is confirmed by molecular genetic testing. Neurological involvement typically manifests between 6 and 24 months of age, causing progressive motor dysfunction. Chronic axonal neuropathy is often present on nerve biopsy, and peripheral neuropathy is evident on electrophysiologic studies. Splenectomy and blood transfusions ...

Role Of Extracellular Vesicles In Glia-Neuron Intercellular Communication, 2022 Jamia Hamdard University
Role Of Extracellular Vesicles In Glia-Neuron Intercellular Communication, Shahzad Ahmad, Rohit K Srivastava, Pratibha Singh, Ulhas P. Naik, Amit K Srivastava
Department of Medicine Faculty Papers
Cross talk between glia and neurons is crucial for a variety of biological functions, ranging from nervous system development, axonal conduction, synaptic transmission, neural circuit maturation, to homeostasis maintenance. Extracellular vesicles (EVs), which were initially described as cellular debris and were devoid of biological function, are now recognized as key components in cell-cell communication and play a critical role in glia-neuron communication. EVs transport the proteins, lipids, and nucleic acid cargo in intercellular communication, which alters target cells structurally and functionally. A better understanding of the roles of EVs in glia-neuron communication, both in physiological and pathological conditions, can aid ...

The interindividual variation in the functional response of platelets to activation by agonists is heritable. Genome-wide association studies (GWASs) of quantitative measures of platelet function have identified fewer than 20 distinctly associated variants, some with unknown mechanisms. Here, we report GWASs of pathway-specific functional responses to agonism by adenosine 5'-diphosphate, a glycoprotein VI-specific collagen mimetic, and thrombin receptor-agonist peptides, each specific to 1 of the G protein-coupled receptors PAR-1 and PAR-4, in subsets of 1562 individuals. We identified an association (P = 2.75 × 10-40) between a common intronic variant, rs10886430, in the G protein-coupled receptor kinase 5 gene (GRK5 ...

The Involvement Of Oxidative Stress In Non-Hodgkin’S Lymphomas; A Review Of The Literature, Ramona Ingrid Corbeanu, Amelia Maria Găman
Journal of Mind and Medical Sciences
Non-Hodgkin’s malignant lymphomas are a heterogeneous group of hematological malignancies, characterized by a variety of clinical, morphological, histopathological, immuno-histochemical, molecular and evolutionary features. They represent a form of cancer that develops from the lymphatic tissue, as a result of the malignant transformation of B (85%) or T (15%) lymphocytes. Lymphomagenesis is described as a multi-stage process involving the mutation and proliferation of cell clones. Oxidative stress is defined as an imbalance of cellular redox status caused by the production of reactive oxygen species (ROS) and/ or by decreasing antioxidant systems that allows their accumulation in the cell. Small quantities ...

Transformative Medicine (T-Med)
Malingering can be a difficult diagnosis to discern, especially in patients with well-crafted stories presenting with signs and symptoms that align directly with the literature. This can further become a challenge when a patient is malingering in the setting of a rare disease, where many complaints can be subjective in nature and not entirely testable by physical exam alone. Malingering is responsible for billions of dollars of healthcare waste every single year, and this report can serve as a guide of history elements, signs and symptoms to look out for with patients malingering in the setting of the porphyrias. It ...
