Real-world data on the clinical features, therapy patterns, and outcomes of older adults with diffuse large B-cell lymphoma in Latin America: A study from the Grupo de Estudio Latinoamericano de Linfoproliferativos (GELL).

Introduction: Diffuse large B-cell lymphoma (DLBCL) is the most common type of B-cell lymphoma, predominantly afflicting older adults. There remains a notable absence of data regarding DLBCL in older adults in Latin America.

Materials And Methods: We conducted a retrospective analysis of 608 newly diagnosed Latin American patients with DLBCL aged ≥65 years.

Retrospective Multicenter Real-Life Study on the First-Line Treatment of Classical Hodgkin Lymphoma in Argentina.

There are no data in Argentina on the response rates to first-line treatment of classical Hodgkin Lymphoma (cHL) outside clinical trials. A total of 498 patients from 7 public and private hospitals in Argentina were retrospectively examined. The median follow-up was 37.

Long-term follow-up of essential thrombocythemia patients treated with anagrelide: subgroup analysis according to JAK2/CALR/MPL mutational status.

Background: Anagrelide represents a treatment option for essential thrombocythemia, although its place in therapy remains controversial.

Aim: To assess the impact of mutational status in response rates and development of adverse events during long-term use of anagrelide.

Methods: We retrospectively evaluated 67 patients with essential thrombocythemia treated with anagrelide during 68 (4-176) months.

Test of an electronic program to query clinicians about nonspecific causes reported for pneumonia deaths, New York City, 2012.

We tested an electronic cause-of-death query system at a hospital in New York City to evaluate clinicians' reporting of cause of death. We used the system to query clinicians about all deaths assigned International Classification of Disease code J189 (pneumonia, unspecified) as the underlying cause of death. Of 29 death certificates that generated queries, 28 were updated with additional information, which led to revisions in the underlying cause of 27 deaths.

Screening for MPL mutations in essential thrombocythemia and primary myelofibrosis: normal Mpl expression and absence of constitutive STAT3 and STAT5 activation in MPLW515L-positive platelets.

Objectives: To evaluate the frequency of MPL W515L, W515K and S505N mutations in essential thrombocythemia (ET) and primary myelofibrosis (PMF) and to determine whether MPLW515L leads to impaired Mpl expression, constitutive STAT3 and STAT5 activation and enhanced response to thrombopoietin (TPO).

Methods: Mutation detection was performed by allele-specific PCR and sequencing. Platelet Mpl expression was evaluated by flow cytometry, immunoblotting and real-time RT-PCR.
