Fluorescence Enhancement by Metal- Core/Silica-Shell Nanoparticles**

Abstract: Fluorescent nanoparticles have been synthesized with a metal core, silica-spacer shell, and a dye-labeled silica shell. Cascade-yellow-labeled, silver-core and carboxyfluorescein-labeled, gold-core nanoparticles with dye–metal distances of 24–25 nm exhibit fluorescence enhancement factors as high as 12.5 and 6.8, respectively. Cascade-yellow-labeled, gold-core particles with a dye–metal distance of ∼15 nm show significant fluorescence quenching.

Safety and activity of ibrutinib plus rituximab for patients with high-risk chronic lymphocytic leukaemia: a single-arm, phase 2 study

Abstract: Summary Background Ibrutinib, an orally administered covalent inhibitor of Bruton's tyrosine kinase (BTK), is an effective treatment for relapsed chronic lymphocytic leukaemia (CLL). We investigated the activity and safety of the combination of ibrutinib with the monoclonal antibody rituximab in patients with high-risk CLL. Methods In this single-arm phase 2 study, we enrolled adult patients with high-risk CLL at the MD Anderson Cancer Center (Houston, TX, USA). All enrolled participants had high-risk cytogenetic abnormalities (deletion 17p, TP53 mutation, or deletion 11q) or a short progression-free survival (PFS 2 , intravenously, every week during cycle 1, then once per cycle until cycle 6), followed by continuous daily single-agent ibrutinib 420 mg until disease progression or until toxicities or complications precluded further treatment. The primary endpoint was progression-free survival in the intention-to-treat population. This study is registered with ClinicalTrials.gov number NCT01520519, and is no longer accruing patients. Findings Between Feb 28, 2012, and Sept 11, 2012, we enrolled 40 patients with CLL with high-risk disease features, 20 of whom had deletion 17p (del[17p]) or TP53 mutations (16 previously treated, four untreated), 13 had relapsed CLL with deletion 11q (del[11q]), and seven a PFS less than 36 months after first-line chemoimmunotherapy. 18-month PFS in all patients was 78·0% (95% CI 60·6–88·5), whereas in those with a del(17p) or TP53 mutation it was 72·4% (45·6–87·6) Toxicity was mainly mild to moderate in severity (grade 1–2). Diarrhoea occurred in ten (25%) patients (grade 1 in nine patients and grade 2 in one), bleeding events in 14 (33%) patients (eight grade 1 and five grade 2), nausea or vomiting in 15 patients (38%) (ten grade 1 and five grade 2), and fatigue in seven (18%) patients (four grade 1 and three grade 2). Five patients (13%) had grade 3 infections (two lung infections, one upper respiratory tract infection, one sepsis, and one mucositis), and no grade 4 or 5 infections occurred. One patient had grade 4 neutropenia. Interpretation The encouraging safety and activity of ibrutinib and rituximab in this population of patients with high-risk CLL merits further investigation of this combination.

Empagliflozin and Clinical Outcomes in Patients With Type 2 Diabetes Mellitus, Established Cardiovascular Disease, and Chronic Kidney Disease

Abstract: Background: Empagliflozin, a sodium-glucose cotransporter 2 inhibitor, reduced cardiovascular morbidity and mortality in patients with type 2 diabetes mellitus and established cardiovascular disease in the EMPA-REG OUTCOME trial (Empagliflozin Cardiovascular Outcome Event Trial in Type 2 Diabetes Mellitus Patients). Urinary glucose excretion with empagliflozin decreases with declining renal function, resulting in less potency for glucose lowering in patients with kidney disease. We investigated the effects of empagliflozin on clinical outcomes in patients with type 2 diabetes mellitus, established cardiovascular disease, and chronic kidney disease. Methods: Patients with type 2 diabetes mellitus, established cardiovascular disease, and estimated glomerular filtration rate (eGFR) ≥30 mL·min −1 ·1.73 m −2 at screening were randomized to receive empagliflozin 10 mg, empagliflozin 25 mg, or placebo once daily in addition to standard of care. We analyzed cardiovascular death, hospitalization for heart failure, all-cause hospitalization, and all-cause mortality in patients with prevalent kidney disease (defined as eGFR −1 ·1.73 m −2 and/or urine albumin-creatinine ratio >300 mg/g) at baseline. Additional analyses were performed in subgroups by baseline eGFR ( −1 ·1.73 m −2 ) and baseline urine albumin-creatinine ratio (>300, 30–≤300, Results: Of 7020 patients treated, 2250 patients had prevalent kidney disease at baseline, of whom 67% had a diagnosis of type 2 diabetes mellitus for >10 years, 58% were receiving insulin, and 84% were taking angiotensin-converting enzyme inhibitors or angiotensin receptor blockers. In patients with prevalent kidney disease at baseline, empagliflozin reduced the risk of cardiovascular death by 29% compared with placebo (hazard ratio [HR], 0.71; 95% confidence interval [CI], 0.52–0.98), the risk of all-cause mortality by 24% (HR, 0.76; 95% CI, 0.59–0.99), the risk of hospitalization for heart failure by 39% (HR, 0.61; 95% CI, 0.42–0.87), and the risk of all-cause hospitalization by 19% (HR, 0.81; 95% CI, 0.72–0.92). Effects of empagliflozin on these outcomes were consistent across categories of eGFR and urine albumin-creatinine ratio at baseline and across the 2 doses studied. The adverse event profile of empagliflozin in patients with eGFR −1 ·1.73 m −2 was consistent with the overall trial population. Conclusions: Empagliflozin improved clinical outcomes and reduced mortality in vulnerable patients with type 2 diabetes mellitus, established cardiovascular disease, and chronic kidney disease.
