RESUMO

We retrospectively evaluated the role of rituximab (R) in maintenance treatment after autologous stem cell transplantation performed in patients with relapsed follicular lymphoma. We compared the outcome of 67 follicular lymphoma (FL) patients according to the use of rituximab maintenance (RM) or not. All patients received rituximab plus chemotherapy before autologous stem-cell transplantation (ASCT). Patients received median of two lines of prior therapy. The RM schedule was one injection of rituximab every 3 months for 2 years. Median follow-up is 4.6 years. The 3-year progression-free survival (PFS) after ASCT was 86 % with RM vs. 46 % without (p = 0.0045). Median is not reached in the RM arm vs. 31 months in non-RM arm. The 3-year OS was 96 % with RM vs. 78 % without (p = 0.059). The present monocentric study shows that 2 years of RM after ASCT significantly increases response duration for non-naive rituximab relapsed FL patients compared with observation.

RESUMO

BACKGROUND: Peripheral T-cell lymphomas (PTCLs) are rare and heterogeneous diseases with dismal outcome when treated with chemotherapy alone. Because allogeneic stem-cell transplantation (allo-SCT) can cure relapse/refractory patients, we hypothesized that upfront allo-SCT may provide a better outcome. Therefore, all patients that presented with advanced PTCL in our institution at diagnosis were scheduled to undergo upfront allo-SCT after induction chemotherapy. PATIENTS AND METHODS: The aim of the present work was to assess the feasibility and toxicity of upfront allo-SCT. From 2004 to 2012, 49 newly diagnosed PTCL patients were scheduled to receive upfront allo-SCT. A human leukocyte antigen-matched donor was found for 42 patients: related to the patient in 15 cases, unrelated in 20 cases, and suitable cord blood units were used in 7 cases. RESULTS: After induction chemotherapy, 17 patients reached complete remission and 29 (60%) proceeded to upfront allo-SCT. For all patients, the 1 and 2-year overall survival (OS) rates were 59% [95% confidence interval (CI) 47-75] and 55% (95% CI 43-71), respectively. The most frequent reason we did not proceed to allo-SCT was disease progression or insufficient response after induction. For transplanted patients, the 1- and 2-year OS were 76% (95% CI 62-93) and 72.5% (95% CI 58-91), respectively. Toxicity-related mortality (TRM) 1 year after allo-SCT was only 8.2% (95% CI 0-18.5). The 2-year progression-free survival (PFS) rate of patients who did not proceed to allo-SCT (n = 20) was below 30%. The disease status at the time of transplantation was a strong predictive marker for both PFS and OS in transplant patients. CONCLUSIONS: Upfront allo-SCT in PTCLs is feasible with low TRM, and it provides long-term disease control. However, one-third of patients remain chemo-refractory and, thus, new therapeutic approaches are warranted. The role of upfront allo-SCT compared with other therapeutic approaches in PTCLs requires investigation in randomized studies.

RESUMO

BACKGROUND: Medline/PubMed is the most frequently used medical bibliographic research database. The aim of this study was to propose a new generic method to limit any Medline/PubMed query based on the relative impact factor and the A & B categories of the SIGAPS score. MATERIAL AND METHODS: The entire PubMed corpus was used for the feasibility study, then ten frequent diseases in terms of PubMed indexing and the citations of four Nobel prize winners. The relative impact factor (RIF) was calculated by medical specialty defined in Journal Citation Reports. The two queries, which included all the journals in category A (or A OR B), were added to any Medline/PubMed query as a central point of the feasibility study. RESULTS: Limitation using the SIGAPS category A was larger than the when using the Core Clinical Journals (CCJ): 15.65% of PubMed corpus vs 8.64% for CCJ. The response time of this limit applied to the entire PubMed corpus was less than two seconds. For five diseases out of ten, limiting the citations with the RIF was more effective than with the CCJ. For the four Nobel prize winners, limiting the citations with the RIF was more effective than the CCJ. CONCLUSION: The feasibility study to apply a new filter based on the relative impact factor on any Medline/PubMed query was positive.

RESUMO

INTRODUCTION: Conflict of interests (COIs) adversely affect the integrity of science and public health. The role of medical schools in the teaching and management of COIs has been highlighted by the publication of an annual evaluation of American medical schools based on their COIs policies by the American Medical Student Association (AMSA). A deontological charter was adopted by French medical schools in 2018 but its impact on COI comprehension by students and its effects on COI prevention were not evaluated. METHODS: A 10-item direct survey was conducted among about 1000 students in Paris-Cité University in order to investigate the respect of the charter regarding COIs both in the medical school and in affiliated teaching hospitals. RESULTS: Cumulative results show a satisfying respect of prevention policies regarding COIs in the medical school and hospitals despite the fact that the existence of the charter and its major aspects were insufficiently known. Disclosure of COIs by teachers was insufficient. CONCLUSION: This first direct study among students shows better results than expected according to current non-academic surveys. Moreover, this study demonstrates the feasibility of this kind of survey whose repetition should be an appropriate tool to improve the implementation of the charter within medical schools and teaching hospitals, in particular mandatory disclosure of COIs by teachers.

RESUMO

BACKGROUND: There is no consensual first-line chemotherapy for elderly patients with mantle cell lymphoma (MCL). The GOELAMS (Groupe Ouest-Est des Leucémies Aiguës et Maladies du Sang) group previously developed the (R)VAD+C regimen (rituximab, vincristine, doxorubicin, dexamethasone and chlorambucil), which appeared as efficient as R-CHOP (rituximab, cyclophosphamide, doxorubicine, vincristine, prednisone) while less toxic. Based on this protocol, we now added bortezomib (RiPAD+C: rituximab, bortezomib, doxorubicin, dexamethasone and chlorambucil) given its efficacy in relapsed/refractory MCL patients. The goal of the current phase II trial was to evaluate the feasibility and efficacy of the RiPAD+C regimen as frontline therapy for elderly patients with MCL. PATIENTS AND METHODS: Patients between 65 and 80 years of age with newly diagnosed MCL received up to six cycles of RiPAD+C. RESULTS: Thirty-nine patients were enrolled. Median age was 72 years (65-80). After four cycles of RiPAD+C, the overall response rate was 79%, including 51% complete responses (CRs). After six cycles, CR rate increased up to 59%. After a 27-month follow-up, median progression-free survival (PFS) is 26 months and median overall survival has not been reached. Four patients (10%) discontinued the treatment because of a severe toxicity and seven patients (18%) experienced grade 3 neurotoxicity. CONCLUSION: The bortezomib-containing RiPAD+C regimen results in high CR rates and prolonged PFS with predictable and manageable toxic effects in elderly patients with MCL.

RESUMO

BACKGROUND: In non-cutaneous T-cell/natural killer (T/NK) lymphomas, the prognostic value of (18)F-fluorodeoxyglucose-positron emission tomography (FDG-PET) during or after therapy is unknown. PATIENTS AND METHODS: In this retrospective study, 54 T/NK lymphoma patients were assessed using FDG-PET before (n = 40), during (n = 44) and/or after therapy (n = 31). RESULTS: FDG-PET showed an abnormal FDG uptake in all cases. Interim FDG-PET was negative in 25 of 44 cases. After completion of therapy, 19 of 31 patients reached complete remission with negative FDG-PET. In ALK+ anaplastic large cell lymphomas, the 4-year progression-free survival (PFS) was 80% and the negative predictive value of post-therapy FDG-PET was 83% (n = 9). In ALK- T/NK lymphomas, the 4-year PFS was 59% for patients with a negative interim FDG-PET versus 46% for patients with a positive interim FDG-PET (P = 0.28, n = 35). Similarly, there was no statistical difference in 4-year PFS between negative and positive post-therapy FDG-PET in these lymphomas (51% and 67%, respectively, P = 0.96). The 4-year cumulative incidence of relapse from a negative post-therapy FDG-PET was 53% in ALK- T/NK lymphomas. CONCLUSIONS: Although T/NK lymphomas are FDG-avid at diagnosis, a negative interim or post-therapy FDG-PET does not translate into an improved PFS in ALK- T/NK lymphomas.

RESUMO

The deleterious consequences of "predatory" journals are numerous, whether the researcher submitted his work to them naively or knowingly: work little or not read by the international community in the absence of indexing and disappearance of any digital trace in the absence of archiving. The reputation of researchers but also of universities and research organizations and the credit of science for citizens can be sustainably damaged. These open access journals, with the author who pays as model, represent as many resources unavailable for legitimate journals. A joint mobilization of all the actors involved is necessary: researchers, universities and faculties of medicine, sections of the national university council, publishers of legitimate journals, research organizations, learned societies, ethics committees, funders, media and political decision-makers. Publishing in a predatory journal is now a scientific misconduct.

RESUMO

The "author-pay" model of open access publication, which appeared in 2002, allocates to the author or his institution the costs of processing articles due to the journal after acceptance, for an amount of a few hundred to several thousand euros. New publishers emerged towards the end of the 2000s, which used this model but with purely commercial objectives, offering naive authors and/or wishing to quickly expand their curriculum vitae by publications in "predatory journals". They are characterized by aggressive e-mail solicitations, lack of ethics, lack of details about the publisher and the editorial board, poor peer review, unspecified and low fees for processing articles, a lack of indexing and the promise of rapid publication.

RESUMO

Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) is a recessively inherited monogenic disease caused by a mutation in the autoimmune regulator (AIRE) gene. AIRE plays a major role in central (thymic) immune tolerance. In the absence of AIRE, autoimmunity develops that is especially targeted at endocrine tissues. T-cell large granular lymphocyte (T-LGL) leukemia is a monoclonal lymphoproliferative disease characterized by persistent and indolent lymphocytosis. Autoimmune manifestations, such as rheumatoid arthritis or autoimmune cytopenia, are also common. We report the case of a patient with APECED, who presented with pure red cell aplasia associated with T-LGL leukemia. The association of T-LGL leukemia and APECED is very rare and may not be fortuitous. The immunological mechanisms of this association are discussed.

RESUMO

The present review article details developments in medical writing and the ongoing transformation of the scientific medical press. With these twin revolutions, French-language scientific medical journals are at a crossroads: are they going to become vehicles of teaching, of popularization, of liaison between members of medical societies, of general public information contributing to decision-making in the field of public health? Or will they maintain their scientific status? Under certain conditions, a move toward French/English bilingualism could be the solution to maintain and advertise their scientific level, while contributing to the quality of medical teaching in French and to the worldwide influence of the French language.

RESUMO

In this report, the authors analyze the revolutions (journal indexing, structuring of medical writing and reviewing, impact of information technology and transformation of the medical press's business model) that, in a very short space of time, have profoundly affected the world of medical writing, which has now come under the fire of "predatory" journals.

RESUMO

We evaluated the way in which medical students interacted with a surgical education Website. Ten medical students on their paediatric surgery rotation were asked to study online a chapter on intussusception in young children, for a period of 1 h. The computer was connected by video link to a video-recorder that recorded their navigation movements, i.e. navigation time, time spent in front of each page, stepwise, progressive exploration of the surgical contents, and use of interactive links. The students were asked to complete a questionnaire to identify their overall competency in computers and Internet navigation capabilities. The mean time spent viewing the entire Website was 48 min (range 31-63) and the mean time spent on the assigned chapter was 38 min (range 8-53). Each page out of 14 within the chapter was visited a mean of 1.8 times (range 0-10). Access to video selections occurred after a mean of 10 min after beginning the session. A connection was made to the video a mean of 2.3 times per session. The mean time spent viewing video footage was 9 min (24% of the time spent viewing the chapter). The questionnaire results showed that few students regularly accessed the Internet for educational purposes.

RESUMO

INTRODUCTION: To study how competence is described and perceived by organizations of healthcare professionals in France and propose approaches toward implementing a policy to monitor and assess competence throughout medical professionals' careers. METHODS: After a literature search, we sent 160 letters to organizations representing 16 healthcare professions (listed in the French healthcare code) describing our objectives and proposing interviews. Semi-structured interviews (45-90 minutes) were conducted. The principle questions asked were: What is your organization's definition of competence? What are the principal elements that define competence in healthcare activities? How can a system for assessing competence be implemented? Which methods for such a system are most appropriate, based on experience in other countries? Who are the players in the field of competence? How can organizations participate in monitoring competence? RESULTS: 265 people representing 148 French organizations were interviewed. Analysis of the interviews showed that the principal points mentioned included: need for recognition; lack of training on new developments; need to anticipate changes; need for better health security in the healthcare system. There was a general consensus on the basic elements of competence, the responsibility of public institutions and professional organizations, and the need to work together. DISCUSSION: We suggest that competence in health care should be defined as follows: "professional competence is based on an initial diploma, participation in effective continuing medical education, a minimum amount of professional activity, and a regular peer review process". Healthcare professionals in France would like to have a better system that allows them to exchange more information on the principal issues in health care.
