Growth and yield of turmeric (Curcuma longa L.) intercropped in poplar (Populus deltoides Bartram ex Marshall) plantation at Punjab

The effect of planting dates and methods of planting of turmeric (Curcuma longa) intercroppedin poplar (clone Udai) (Poplulus deltoides) plantation was studied at Ludhiana (Punjab,India). The treatments consisted of three planting dates namely, 20th March, 20th April and20th May and two methods of planting, namely, ridge and flat method (60 cm x 10 cm) inpoplar plantation. The study revealed that in first year of plantation (2004-05), a fresh rhizomeyield of 9.96 t ha-1 was obtained in 20th April planting which was  significantly more thanthat of 20th May planting (9.45 t ha-1). During 2005-06, a fresh rhizome yield of 8.15, 11.61and 13.95 t ha-1 was produced in 20th March, 20th April and 20th May planting dates, respectively.During 2006-07, the yields were lower and the differences in fresh rhizome yield due to 20thMay (6.33 t ha-1) and 20th April (6.43 t ha-1) planting  were not significant but both theplanting dates were significantly better than 20th March (5.6 t ha-1) planting. The ridge methodof planting produced 8.0%, 11.0% and 9.8% more yield which was significantly higher thanflat method of planting during 2004-05, 2005-06 and 2006-07, respectively. &nbsp

Plasma protein C levels in immunocompromised septic patients are significantly lower than immunocompetent septic patients: a prospective cohort study

Introduction: Activated Protein C [APC] improves outcome in immunocompetent patients with severe sepsis particularly in those who are perceived to have high mortality risk. Before embarking on a trial of APC administration in immunocompromised septic patients, a preliminary study on plasma levels of protein C in this cohort is essential

Ibrutinib as initial therapy for patients with chronic lymphocytic leukemia

Background: chronic lymphocytic leukemia (CLL) primarily affects older persons who often have coexisting conditions in addition to disease-related immunosuppression and myelosuppression. We conducted an international, open-label, randomized phase 3 trial to compare two oral agents, ibrutinib and chlorambucil, in previously untreated older patients with CLL or small lymphocytic lymphoma. Methods: we randomly assigned 269 previously untreated patients who were 65 years of age or older and had CLL or small lymphocytic lymphoma to receive ibrutinib or chlorambucil. The primary end point was progression-free survival as assessed by an independent review committee. Results: the median age of the patients was 73 years. During a median follow-up period of 18.4 months, ibrutinib resulted in significantly longer progression-free survival than did chlorambucil (median, not reached vs. 18.9 months), with a risk of progression or death that was 84% lower with ibrutinib than that with chlorambucil (hazard ratio, 0.16; P<0.001). Ibrutinib significantly prolonged overall survival; the estimated survival rate at 24 months was 98% with ibrutinib versus 85% with chlorambucil, with a relative risk of death that was 84% lower in the ibrutinib group than in the chlorambucil group (hazard ratio, 0.16; P=0.001). The overall response rate was higher with ibrutinib than with chlorambucil (86% vs. 35%, P<0.001). The rates of sustained increases from baseline values in the hemoglobin and platelet levels were higher with ibrutinib. Adverse events of any grade that occurred in at least 20% of the patients receiving ibrutinib included diarrhea, fatigue, cough, and nausea; adverse events occurring in at least 20% of those receiving chlorambucil included nausea, fatigue, neutropenia, anemia, and vomiting. In the ibrutinib group, four patients had a grade 3 hemorrhage and one had a grade 4 hemorrhage. A total of 87% of the patients in the ibrutinib group are continuing to take ibrutinib. Conclusions: ibrutinib was superior to chlorambucil in previously untreated patients with CLL or small lymphocytic lymphoma, as assessed by progression-free survival, overall survival, response rate, and improvement in hematologic variables.

Idarubicin dose escalation during consolidation therapy for adult acute myeloid leukemia

Purpose Higher doses of the anthracycline daunorubicin during induction therapy for acute myeloid leukemia (AML) have been shown to improve remission rates and survival. We hypothesized that improvements in outcomes in adult AML may be further achieved by increased anthracycline dose during consolidation therapy. Patients and Methods Patients with AML in complete remission after induction therapy were randomly assigned to receive two cycles of consolidation therapy with cytarabine 100 mg/m daily for 5 days, etoposide 75 mg/m daily for 5 days, and idarubicin 9 mg/m daily for either 2 or 3 days (standard and intensive arms, respectively). The primary end point was leukemia-free survival (LFS). Results Two hundred ninety-three patients 16 to 60 years of age, excluding those with core binding factor AML and acute promyelocytic leukemia, were randomly assigned to treatment groups (146 to the standard arm and 147 to the intensive arm). Both groups were balanced for age, karyotypic risk, and FLT3–internal tandem duplication and NPM1 gene mutations. One hundred twenty patients in the standard arm (82%) and 95 patients in the intensive arm (65%) completed planned consolidation (P, .001). Durations of severe neutropenia and thrombocytopenia were prolonged in the intensive arm, but there were no differences in serious nonhematological toxicities. With a median follow-up of 5.3 years (range, 0.6 to 9.9 years), there was a statistically significant improvement in LFS in the intensive arm compared with the standard arm (3-year LFS, 47% [95% CI, 40% to 56%] v 35% [95% CI, 28% to 44%]; P = .045). At 5 years, the overall survival rate was 57% in the intensive arm and 47% in the standard arm (P = .092). There was no evidence of selective benefit of intensive consolidation within the cytogenetic or FLT3–internal tandem duplication and NPM1 gene mutation subgroups. Conclusion An increased cumulative dose of idarubicin during consolidation therapy for adult AML resulted in improved LFS, without increased nonhematologic toxicity

Significance of Abnormal Protein Bands in Patients with Multiple Myeloma following Autologous Stem Cell Transplantation

Aim: We studied the characteristics of small abnormal protein bands (APB) (including oligoclonal bands and new apparent monoclonal bands) that are frequently detected by serum protein electrophoresis (SPEP) and isoelectric focusing (IEF) in the post-autologous stem cell transplant setting. Methods: In a retrospective analysis of patients with multiple myeloma undergoing transplantation, paraprotein identity and quantification were performed using standard immunofixation electrophoresis. The nature of any new bands was determined by IEF which distinguished between oligoclonal bands and apparent monoclonal bands. Results: Of 49 myeloma cases, the median follow-up was 33.7 months (range, 5.6-97.5 months) and 24 patients had relapsed. Thirty six (73%) developed APB. 22 patients had more than one episode of APB and 6 patients had more than 2 episodes resulting in a total of 69 episodes of APB observed post-transplant. IEF demonstrated 54 of these APB were oligoclonal bands and 15 appeared to be monoclonal. Of the 15 episodes of apparent monoclonal bands, 10 had differing heavy or light chain restriction compared to the original myeloma paraprotein and 5 had the same heavy and light chain restriction but different band location in the SPEP lane. Ten of these apparent monoclonal bands resolved, 5 persisted, and only one represented true disease progression. The presence of APB impacted favourably on event-free survival (p=0.05). Conclusion: Small APB are very frequent post-transplant for myeloma, and IEF can identify these APB as oligoclonal or monoclonal. Apparent monoclonal bands may represent relapsed disease, but in the vast majority of cases it does not, and most likely represents a transient phenomenon representing regeneration of a limited immune response
