Low-dose oral prolonged-release oxycodone/naloxone for chronic pain in elderly patients with cognitive impairment: an efficacy-tolerability pilot study.

Objective: This pilot study evaluated the efficacy and safety of prolonged-release oxycodone/naloxone (OXN-PR) in older subjects with chronic pain and mild-to-moderate cognitive impairment.

Methods: This was a prospective, observational, open-label study of 45-day duration. Patients with moderate-to-severe chronic pain and naïve to strong opioids were recruited from nursing homes and Alzheimer's disease centers.

A short low-dose imatinib trial allows rapid identification of responsive patients in hypereosinophilic syndromes.

Although imatinib may be effective in hypereosinophilic syndromes, the exact response kinetics are not known. Imatinib was administered at 100-400 mg/d each week in a 12-week response-oriented schedule, targeting a complete clinical and haematological remission (CR). CR was achieved in 11/23 patients (6/6 with FIP1L1-PDGRFA rearrangement and 5/17 without, P = 0.

Thrombocytosis and leukocytosis interaction in vascular complications of essential thrombocythemia.

To elucidate the role of thrombocytosis, alone or in combination with standard (age, previous cardiovascular events) and novel (leukocytosis, JAK2(V617F) mutational status) risk factors, in the cardiovascular events of essential thrombocythemia (ET), we analyzed a cohort of 1063 patients. We found that a platelet count at diagnosis greater than 1000 x 10(9)/L was associated with significantly lower rate of thrombosis in multivariable analysis and, if combined with leukocytes less than 11 x 10(9)/L, pointed to a "low-risk" category with a rate of thrombosis of 1.59% of patients/year.

Characteristics and clinical correlates of MPL 515W>L/K mutation in essential thrombocythemia.

Among 994 patients with essential thrombocythemia (ET) who were genotyped for the MPLW515L/K mutation, 30 patients carrying the mutation were identified (3.0%), 8 of whom also displayed the JAK2V671F mutation. MPLW515L/K patients presented lower hemoglobin levels and higher platelet counts than did wild type (wt) MPL; these differences were highly significant compared with MPLwt/JAK2V617F-positive patients.

Leukocytosis and risk stratification assessment in essential thrombocythemia.

Purpose: Established risk factors for thrombosis in essential thrombocythemia (ET) include age and previous vascular events. We aimed to refine this risk stratification by adding baseline leukocytosis.

Patients And Methods: We enrolled 657 patients with ET followed for a median of 4.
