Triple A Plus (AAA) Survival Prediction Model for Essential Thrombocythemia: Analysis Involving 7308 Patients.

Survival prediction models in essential thrombocythemia (ET) include the International Prognostic Scoring System (IPSET) and the more recently introduced triple-A (AAA) prognostic score. The latter enlists age and absolute neutrophil (ANC) and lymphocyte (ALC) counts as risk variables. In the current study, a Mayo Clinic discovery cohort of 658 patients with ET was used to identify AAA-independent risk variables.

Chronic lymphocytic leukemia and associated chronic lung diseases.

Infections are a significant cause of morbidity and mortality in chronic lymphocytic leukemia (CLL), with respiratory tract infections being predominant. This study evaluated the incidence of chronic lung diseases (asthma, COPD, and bronchiectasis) among 4,532 patients with CLL and their association with infection complications and outcomes. We found that bronchiectasis (5%), asthma (12.

Intake of benzodiazepines in treatment naïve chronic lymphocytic leukemia patients is associate with a shorter time to first treatment.

Patients after diagnosis of leukemia face midlife crisis. In some instances, it may be accompanied by anxiety or depression, which may require pharmacological intervention. In this study, we explored the association between benzodiazepine (BZP) usage and time to first treatment (TTFT) in patients with chronic lymphocytic leukemia (CLL) under a watch-and-wait (W&W) approach.

Intake of Proton Pump Inhibitors Is Associated with a Shorter Time to First Treatment in Early-Stage Chronic Lymphocytic Leukemia.

Introduction: Proton pump inhibitors (PPIs) are one of the most widely used drugs worldwide [Gut Liver. 2017;11(1):27-37]. The use of PPI has become a common practice and is overprescribed for all patients with cancer including patients with hematological malignancies.

Vitamin D supplement for patients with early-stage chronic lymphocytic leukemia is associated with a longer time to first treatment.

Low levels of vitamin D are associated with a shorter time to first treatment (TTFT) and inferior overall survival in patients with chronic lymphocytic leukemia (CLL). But whether vitamin D supplement affects the clinical course of patients with CLL, remains an open question. In this study, we aimed to retrospectively explore the clinical benefit of vitamin D supplement or one of its analogs, on TTFT and treatment-free survival (TFS) in a large cohort of patients with asymptomatic CLL, who were under watch-and-wait approach.

Effectiveness of nirmatrelvir plus ritonavir treatment for patients with chronic lymphocytic leukemia during the Omicron surge.

Patients with chronic lymphoid leukemia (CLL), even in the Omicron era and after vaccination, suffer from persistent COVID-19 infection, higher complications, and mortality compared with the general population. In this study, we evaluated retrospectively the effectiveness of nirmatrelvir + ritonavir among 1080 patients with CLL who were infected with severe acute respiratory syndrome coronavirus 2. Nirmatrelvir administration was associated with a reduction in COVID-19-related hospitalization or death by day 35.

A comprehensive analysis of meloxicam particles produced by nanosecond laser ablation as a wet milling technique.

Recently, the number of water insoluble and poorly soluble drug compounds has increased significantly. Therefore, growing interest has been witnessed in different particle size reduction techniques to improve the dissolution rates, transport characteristics and bioavailability of drugs. Laser ablation has proven to be an alternative method to the production of nano- and micrometre-sized drug particles without considerable chemical damage.

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Naturally Acquired Immunity versus Vaccine-induced Immunity, Reinfections versus Breakthrough Infections: A Retrospective Cohort Study.

Background: Waning of protection against infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) conferred by 2 doses of the BNT162b2 vaccine begins shortly after inoculation and becomes substantial within 4 months. With that, the impact of prior infection on incident SARS-CoV-2 reinfection is unclear. Therefore, we examined the long-term protection of naturally acquired immunity (protection conferred by previous infection) compared to vaccine-induced immunity.
