Non-Linear Catching-up and Long-Run Convergence in the Agricultural Productivity of US States

This note investigates convergence of agricultural total factor productivity (TFP) for 48 contiguous states in the US. This is carried out using a recently developed methodology which allows for a clear delineation between catching-up and long-run convergence as well as for the presence of non-linearity in TFP differentials. According to the empirical results, the state TFP dynamics are predominantly long-run converging.Productivity

<p>Abstract</p> <p>Purpose</p> <p>To evaluate the efficacy and the toxicity of front line FOLFOX4 combined with bevacizumab in patients with metastatsic CRC (mCRC).</p> <p>Patients and Methods</p> <p>Chemotherapy-naïve patients with mCRC, received bevacizumab (5 mg/kg every 2 weeks d₁), oxaliplatin (85 mg/m²on d₁), leucovorin (200 mg/m²) on days 1 and 2 and 5-Fluorouracil (400 mg/m²as i.v. bolus and 600 mg/m²as 22 h i.v. continuous infusion on days 1 and 2) every 2 weeks.</p> <p>Results</p> <p>Fifty three patients (46 with a PS 0–1) were enrolled. Complete and partial response was achieved in eight (15.1%) and 28 (52.8%) patients, respectively (ORR: 67.9%; 95% C.I.: 53.8%–92%); 11 (20.7%) patients had stable disease and six (11.3%) progressive disease. With a median follow up period of 13.5 months, time to tumor progression was 11 months while the median survival has not yet been reached; the probability of 1-, 2- and 3- year survival was 79.8%, 63.8% and 58.3%, respectively; Two patients relapsed during the follow up period. Eight (15%) patients underwent metastasectomy with R0 resections. Grade 3–4 neutropenia occurred in 15.1% of patients and one (1.9%) of them presented febrile neutropenia. Non-hematologic toxicity included grade 3 diarrhea (7.6%) and grade 2 and 3 neurotoxicity in 16.9 and 15.1% of patients, respectively. One (1.9%) patient presented pulmonary embolism and one (1.9%) cardiac ischaemia. There was one (1.9%) sudden death after the first cycle.</p> <p>Conclusion</p> <p>The combination of FOLFOX4/bevacizumab appears to be highly effective, well tolerated and merits further evaluation in patients with mCRC.</p

Pharmacokinetics of Ganciclovir after Oral Valganciclovir versus Intravenous Ganciclovir in Allogeneic Stem Cell Transplant Patients with Graft-versus-Host Disease of the Gastrointestinal Tract

AbstractThe pharmacokinetics of ganciclovir after oral valganciclovir versus intravenous ganciclovir were compared in allogeneic stem cell transplant recipients with stable graft-versus-host disease of the gastrointestinal tract. Twenty-two evaluable adult patients were randomized to receive a single dose of open-label study drug (900 mg of oral valganciclovir or 5 mg/kg of intravenous ganciclovir). After a washout period of 2 to 7 days, patients were crossed over to receive the alternate study drug. Ganciclovir and valganciclovir concentrations in plasma were measured over 24 hours after dosing. Noninferiority of 900 mg of valganciclovir relative to intravenous ganciclovir was concluded if the lower limit of the 1-sided 95% confidence interval of the ratio of least-square means of the ganciclovir area under the curve (AUC) for the 2 study drugs was >80%. Valganciclovir was found to be rapidly absorbed and converted into ganciclovir. The ganciclovir exposure after 900 mg of valganciclovir noninferior to that of intravenous ganciclovir (AUC0-∞, 52.1 and 53.8 μg·h/mL, respectively; 95% confidence interval of the ratio of least square means of AUC0-∞, 82.48%-118.02%). Oral valganciclovir could be a useful alternative to intravenous ganciclovir in certain stable stem cell transplant patients who require prophylaxis or preemptive therapy for cytomegalovirus infection

Palifermin for oral mucositis after intensive therapy for hematologic cancers

BACKGROUND: Oral mucositis is a complication of intensive chemotherapy and radiotherapy with no effective treatment. We tested the ability of palifermin (recombinant human keratinocyte growth factor) to decrease oral mucosal injury induced by cytotoxic therapy. METHODS: This double-blind study compared the effect of palifermin with that of a placebo on the development of oral mucositis in 212 patients with hematologic cancers; 106 patients received palifermin (60 microg per kilogram of body weight per day) and 106 received a placebo intravenously for three consecutive days immediately before the initiation of conditioning therapy (fractionated total-body irradiation plus high-dose chemotherapy) and after autologous hematopoietic stem-cell transplantation. Oral mucositis was evaluated daily for 28 days after transplantation. RESULTS: The incidence of oral mucositis of World Health Organization (WHO) grade 3 or 4 was 63 percent in the palifermin group and 98 percent in the placebo group (P\u3c0.001). Among patients with this degree of mucositis, the median duration of mucositis was 6 days (range, 1 to 22) in the palifermin group and 9 days (range, 1 to 27) in the placebo group. Among all patients, regardless of the occurrence of mucositis, the median duration of oral mucositis of WHO grade 3 or 4 was 3 days (range, 0 to 22) in the palifermin group and 9 days (range, 0 to 27) in the placebo group (P\u3c0.001). As compared with placebo, palifermin was associated with significant reductions in the incidence of grade 4 oral mucositis (20 percent vs. 62 percent, P\u3c0.001), patient-reported soreness of the mouth and throat (area-under-the-curve score, 29.0 [range, 0 to 98] vs. 46.8 [range, 0 to 110]; P\u3c0.001), the use of opioid analgesics (median, 212 mg of morphine equivalents [range, 0 to 9418] vs. 535 mg of morphine equivalents [range, 0 to 9418], P\u3c0.001), and the incidence of use of total parenteral nutrition (31 percent vs. 55 percent, P\u3c0.001). Adverse events, mainly rash, pruritus, erythema, mouth and tongue disorders, and taste alteration, were mild to moderate in severity and were transient. CONCLUSIONS: Palifermin reduced the duration and severity of oral mucositis after intensive chemotherapy and radiotherapy for hematologic cancers

Reorganisation of Oncologic Care in Greece: A Proposal

Cancer is becoming a major public health issue as patients enjoy longer survivals than ever before due to the introduction innovative but expensive drugs in the clinic. In addition, the ageing of the population in Greece is expected to increase the absolute incidence of cancer. The National Health System should rapidly and efficiently adapt to the new challenges, including increased pharmaceutical costs. Resources ought to be allocated rationally and efficiently while maintaining adequate coverage for the insured population. Economising due to large-scale operations should be pursued by the governmental single payor (EOPYY), so that affordable coverage remains feasible. Establishment of mechanisms to deal with new and very costly drugs should be put in place. The major changes in anchor oncologic hospitals are needed in order to play a role as regional leaders in oncologic care, including merging of similar divisions, subspecialisation of services and promotion of clinical research. These major centres could coordinate a host of satellite oncology services in other urban hospitals and in the provinces. In addition, joint operations in training and patient care should be pursued with major private centres, without mutual mistrust or obsolete inflexibilities. The current financial crisis represents an excellent opportunity for revisioning and restructuring oncologic care in Greece, taking into account the societal needs and based on flexibility and efficiency

Review of (90)Y-ibritumomab tiuxetan as first-line consolidation radio-immunotherapy for B-cell follicular non-Hodgkin&amp;rsquo;s lymphoma

Christos EmmanouilidesDepartment of Medical Oncology, Interbalkan Hospital, Thessaloniki, GreeceAbstract: Several studies have indicated that radioimmunotherapy is an effective and clinically relevant complementary therapeutic approach for patients with B-cell non-Hodgkin&amp;rsquo;s lymphoma (NHL) and may convert partial to complete response when given as consolidation after induction chemotherapy. Yttrium-90(90Y)-ibritumomab tiuxetan (90&amp;Upsilon;-&amp;Iota;&amp;Tau;, Zevalin&amp;reg;, Y2B8) has documented efficacy for both indolent and aggressive NHL. Patients considered eligible for 90Y-IT treatment should satisfy several screening criteria. A recently completed randomized study for patients with follicular lymphoma has demonstrated that 90Y-ibritumomab consolidation also produced a marked prolongation of the median time to progression from 13.5 to 37 months, while partial responders seem to derive relatively more benefit. Other published and ongoing studies explore a similar use for patients with aggressive lymphoma. Studies are comparing the use of 90Y-IT consolidation with the anti-CD20 antibody rituximab maintenance, which is also gaining acceptance. In conclusion, the documented benefit of radioimmunotherapy should be viewed in the context of the goals of treatment and the changing standards of care for lymphoma.
