Phase II study of dose-attenuated bortezomib, cyclophosphamide and dexamethasone ("VCD-Lite") in very old or otherwise toxicity-vulnerable adults with newly diagnosed multiple myeloma.

Objectives: Multiple myeloma (MM) primarily strikes older adults, but full-dose chemotherapy such as bortezomib (Velcade), cyclophosphamide and dexamethasone (VCD) is often excessively toxic to very old or frail adults and those with substantial comorbidities. We piloted dose-attenuated VCD ("VCD-Lite") in such vulnerable adults with newly diagnosed MM (NDMM).

Materials And Methods: Subjects with NDMM and a high risk of therapy-related toxicity due to factors above received bortezomib 1.

Reducing opioid analgesic deaths in America: what health providers can do.

Background: Available data have shown steady increases of drug overdose deaths between 1992 and 2011. We review evidenced-based recommendations provided by a few prominent North American pain societies and suggest ways on how health providers might help reduce opioid analgesic deaths by implementing these practices.

Objective: To identify health care providers' roles in reducing opioid analgesic deaths.

Postbariatric surgery neuropathic pain (PBSNP): case report, literature review, and treatment options.

Objective: This study is aimed at facilitating clinician understanding of factors associated with postbariatric surgery neuropathic pain (PBSNP) and discussing the evidence base for management options.

Design: A case report and systematic literature review.

Methods: A search was conducted of PubMed, MEDLINE, Google Scholar, EMBASE, Psych Info, and Cochrane Database of Reviews for articles published between 1985 and 2013 on neuropathy, pain, and pharmacokinetics associated with postbariatric surgery.

Phase II open label study of the oral vascular endothelial growth factor-receptor inhibitor PTK787/ZK222584 (vatalanib) in adult patients with refractory or relapsed diffuse large B-cell lymphoma.

PTK787/ZK222584 (vatalanib), an orally active inhibitor of vascular endothelial growth factor receptors (VEGFRs), was evaluated in this phase II study of 20 patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL). Patients received once-daily PTK787/ZK222584 at a target dose of 1250 mg. Eighteen patients were evaluable for response: one patient had a complete response (CR), six patients had stable disease but subsequently progressed, 10 patients had progressive disease by three cycles and one subject withdrew before response evaluation.

Re-induction therapy decisions based on day 14 bone marrow biopsy in acute myeloid leukemia.

Purpose: The decision to re-induce patients with acute myeloid leukemia (AML) based on results of the day 14 bone marrow (BM) biopsy is variable and lacks evidence based data. The aim of our review was to evaluate the accuracy of a day 14 BM biopsy in determining the need for re-induction chemotherapy.

Methods: Seventy-four patients with newly diagnosed de novo AML treated with induction chemotherapy were retrospectively reviewed for the purpose of evaluating treatment decisions and outcomes based on their day 14 BM biopsy.

Phase II study of cenersen, an antisense inhibitor of p53, in combination with fludarabine, cyclophosphamide and rituximab for high-risk chronic lymphocytic leukemia.

Patients with chronic lymphocytic leukemia (CLL) with deletion or mutation of TP53 have exceedingly poor clinical outcomes. Cenersen, an oligonucleotide targeting TP53, has been shown to abrogate the activity of TP53 gain-of-function mutants and to increase sensitivity of lymphoma cells to cytotoxic chemotherapy in vitro. We combined cenersen with fludarabine, cyclophosphamide and rituximab (FCR) as treatment for patients with high-risk CLL.

Overcoming drug resistance in mantle cell lymphoma using a combination of dose-dense and intense therapy.

We present a study of the prevalence of genetic polymorphisms and expression of genes encoding the drug-resistance proteins glutathione S-transferases (GSTs) in order to gain insights into the pattern of failure evident in mantle cell lymphoma. We note a high preponderance of genetic alterations conferring resistance to standard chemotherapy in this illness. Concurrent with this investigation, we present a series of patients who were provided dose-dense and intense chemotherapy to circumvent these drug-resistance mechanisms.

A genomic approach to improve prognosis and predict therapeutic response in chronic lymphocytic leukemia.

Purpose: Chronic lymphocytic leukemia (CLL) is a B-cell malignancy characterized by a variable clinical course. Several parameters have prognostic capabilities but are associated with altered response to therapy in only a small subset of patients.

Experimental Design: We used gene expression profiling methods to generate predictors of therapy response and prognosis.

Outcomes of patients who undergo aggressive induction therapy for secondary acute myeloid leukemia.

Background: Response and survival in 96 patients with secondary acute myeloid leukemia (sAML) who received aggressive induction chemotherapy was reviewed.

Methods: The median follow-up of survivors was 2.3 years.

Perinatal malnutrition programs sustained alterations in nitric oxide released by activated macrophages in response to fluoxetine in adult rats.

Objective: Nutritional restriction during lactation has long-term consequences on the functioning of neuroimmune systems. Receptors and transporter serotonin (5-HT) are present in macrophages and may influence their role. This study evaluated nitric oxide release by alveolar macrophages (AMs) in adult control rats and rats malnourished during lactation in response to different fluoxetine (FLX) concentrations and 5-HT(1A) and 5-HT(1B) agonists at different times.

Phase I evaluation of gemcitabine, mitoxantrone, and their effect on plasma disposition of fludarabine in patients with relapsed or refractory acute myeloid leukemia.

Our aim was to estimate the duration of maximum tolerated dose (MTD) duration for gemcitabine given as a continuous infusion in combination with fludarabine and mitoxantrone and to evaluate potential pharmacokinetic (PK) interactions in 17 patients with refractory or relapsed acute myeloid leukaemia (AML). Gemcitabine was administered at 10 mg/m(2)/min for 3-15 h, fludarabine at 25 mg/m(2) daily for days 1-5 and mitoxantrone at 10 mg/m(2) daily on days 1-3. PK studies revealed that fludarabine clearance was not affected by gemcitabine but mean terminal half-life and volume of distribution of fludarabine were slightly increased.

A program of moderate physical training for Wistar rats based on maximal oxygen consumption.

Moderate physical training is often associated with improved cardiorespiratory fitness in athletes and the general population. In animals, studies are designed to investigate basic physiology that could be invasive and uncomfortable for humans. The standardization of an exercise training protocol for rats based on maximal consumption of oxygen (VO(2)max) is needed.

Clinical and molecular predictors of disease severity and survival in chronic lymphocytic leukemia.

Several parameters may predict disease severity and overall survival in chronic lymphocytic leukemia (CLL). The purpose of our study of 190 CLL patients was to compare immunoglobulin heavy chain variable region (IgV(H)) mutation status, cytogenetic abnormalities, and leukemia cell CD38 and Zap-70 to older, traditional parameters. We also wanted to construct a simple, inexpensive prognosis score that would significantly predict TTT and survival in patients at the time of diagnosis and help practicing clinicians.

Partially matched, nonmyeloablative allogeneic transplantation: clinical outcomes and immune reconstitution.

Purpose: Allogeneic transplantation is typically limited to younger patients having a matched donor. To allow a donor to be found for nearly all patients, we have used a nonmyeloablative conditioning regimen in conjunction with stem cells from a related donor with one fully mismatched HLA haplotype.

Patients And Methods: Fludarabine, cyclophosphamide, and alemtuzumab were used as the preparatory regimen.

Thie expression of an intraspecific aggressive reaction in the face of a stressor agent alters the immune response in rats.

The repercussion on the immune response of the expression of intraspecific aggressiveness in the face of a stressor agent was investigated in rats. Ninety-day-old animals were divided into three groups: the control group (only immunological measurements were performed), the foot-shock (FS) (animals individually receiving FS), and the intraspecific aggressive response (IAR) group (animals receiving FS and presenting IAR). For immunological measurements, blood samples were collected promptly at 7 and 15 days after FS or IAR.

Dose-intense cyclophosphamide and etoposide for patients with refractory or high-risk non-Hodgkin's lymphoma.

A retrospective review was performed on the toxicity and response to one cycle of dose-intense cyclophosphamide/etoposide, followed by consolidation in patients with refractory or previously untreated, high-risk non-Hodgkin's lymphoma (NHL). Fifty-five patients with refractory NHL and 13 with untreated, high-risk NHL were administered one cycle of daily cyclophosphamide 1.5 g/m2 intravenously on days 1-4 and etoposide 300 mg/m2 intravenously every 12 hours on days 1-3.

Low-dose weekly paclitaxel for recurrent or refractory aggressive non-Hodgkin lymphoma.

Background: Many patients with recurrent, intermediate or high-grade non-Hodgkin lymphoma (NHL) may not respond to or are not candidates for aggressive salvage chemotherapy. Effective, less toxic regimens are needed. Although high-dose taxanes have not been reported to be very effective for the treatment of lymphoma, different delivery rates may allow for different mechanisms of action to be manifest and result in a different toxicity profile and response rate.

Clinical course and flow cytometric analysis of paroxysmal nocturnal hemoglobinuria in the United States and Japan.

: To determine and directly compare the clinical course of white and Asian patients with paroxysmal nocturnal hemoglobinuria (PNH), data were collected for epidemiologic analysis on 176 patients from Duke University and 209 patients from Japan. White patients were younger with significantly more classical symptoms of PNH including thrombosis, hemoglobinuria, and infection, while Asian patients were older with more marrow aplasia. The mean fraction of CD59-negative polymorphonuclear cells (PMN) at initial analysis was higher among Duke patients than Japanese patients.

Phase 1 trial study of 131I-labeled chimeric 81C6 monoclonal antibody for the treatment of patients with non-Hodgkin lymphoma.

We report a phase 1 study of pharmacokinetics, dosimetry, toxicity, and response of (131)I anti-tenascin chimeric 81C6 for the treatment of lymphoma. Nine patients received a dosimetric dose of 370 MBq (10 mCi). Three patients received an administered activity of 1480 MBq (40 mCi), and 2 developed hematologic toxicity that required stem cell infusion.

Malnutrition during brain growth spurt alters the effect of fluoxetine on aggressive behavior in adult rats.

Malnutrition effect during the suckling period on aggressive behavior was investigated in adult rats treated and not treated with fluoxetine, a selective serotonin reuptake inhibitor. Sixty-four Wistar male rats were allocated in two groups, according to their mothers' diet during lactation. The well-nourished group was fed by mothers receiving a 23% protein diet; the malnourished one by mothers receiving a 8% protein diet.

Rituximab in lymphocyte predominance Hodgkin's disease: a case series.

Rituximab in combination with chlorambucil or radiation therapy may be an effective and less-toxic therapeutic alternative for patients with lymphocyte predominance Hodgkin's disease (LPHD). We treated 6 patients with LPHD with weekly rituximab at 375 mg/m2 for 4 weeks, followed by either radiation therapy or chlorambucil. Four patients had previously untreated disease and 2 had relapsed LPHD.

Increased expression of anti-apoptosis genes in peripheral blood cells from patients with paroxysmal nocturnal hemoglobinuria.

Resistance to apoptosis has been described in neutrophils from patients with PNH and related hematologic disorders (aplastic anemia, myelodysplastic syndrome), but its molecular basis is not understood. Using gene expression analysis, PNH granulocytes had relative overexpression of four anti-apoptosis genes (human A1, hHR23B, Mcl-1, and RhoA) compared to normal controls. These findings were confirmed by RT-PCR analysis and observed in both peripheral blood granulocytes and mononuclear cells of patients with PNH.
