Venous thromboembolism (VTE) risk is increased in patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). A key question was whether increased intensity of anticoagulation would help prevent VTE and improve patient outcomes, including transfer to the intensive care unit (ICU) and mortality. At the start of the coronavirus disease-19 (COVID-19) pandemic, our institution, Boston Medical Center, instituted a VTE risk stratification protocol based on patients' initial D-dimer levels, medical history, and presence of thrombosis to determine whether they should receive standard-dose prophylaxis, high-dose prophylaxis, or therapeutic anticoagulation.

We investigated the safety and efficacy of propylene glycol-free melphalan (PGF-Mel) during HDM/SCT in patients with AL amyloidosis (ClinicalTrials.gov identifier NCT02994784).

This condition is known as neutropenia. Neutropenia accompanied by a fever is referred to as febrile neutropenia, a common side effect of chemotherapy with a high mortality rate.

HTLV-1 may lead to complications, including adult T cell leukemia-lymphoma (ATLL) and HTLV-1-associated myelopathy. Immunosuppression may result in progression from an asymptomatic carrier state to ATLL.

We herein report the case of a 59-year-old male who presented with stable exertional dyspnoea and persistent lung infiltrates who was referred to our hospital for further assessment. A computed tomography (CT)-guided core biopsy was performed showing a dense lymphoid infiltrate, with further testing revealing the diagnosis of pulmonary MALT lymphoma.

A history of malignancy is often considered a contraindication for kidney transplantation. While the desire to transplant a 'cancer-free' patient is understandable, the current approach neglects the heterogeneity in the natural history of cancers, even within a given tumor type. The information used to formulate current guidelines are dated and fail to reflect the vast resource of modern oncology clinical trials data that should more accurately predict the expected overall survival and recurrence risk of cancer patients.
View Article and Find Full Text PDFAL amyloidosis and transthyretin (ATTR) amyloidosis are the most frequent forms of systemic amyloidosis diagnosed in the United States. Macroglossia is considered to be a pathognomonic feature of AL amyloidosis. We report on two cases of systemic amyloidosis with macroglossia that defied routine clinical diagnosis, in which the deposits were typed as ATTR in one case and AL in the other using immunoelectron microscopy.
