Monosomal karyotype in MDS: explaining the poor prognosis? Leukemia 2013; 27:1988-95.

Abstract
Monosomal karyotype (MK) is associated with an adverse prognosis in patients in acute myeloid leukemia (AML). This study analyzes the prognostic impact of MK in a cohort of primary, untreated patients with myelodysplastic syndromes (MDS). A total of 431 patients were extracted from an international database. To analyze whether MK is an independent prognostic marker in MDS, cytogenetic and clinical data were explored in uni- and multivariate models regarding overall survival (OS) as well as AML-free survival. In all, 204/431 (47.3%) patients with MK were identified. Regarding OS, MK was prognostically significant in patients with ≤ 4 abnormalities only. In highly complex karyotypes (≥ 5 abnormalities), MK did not separate prognostic subgroups (median OS 4.9 months in MK+ vs 5.6 months in patients without MK, P=0.832). Based on the number of abnormalities, MK-positive karyotypes (MK+) split into different prognostic subgroups (MK+ and 2 abnormalities: OS 13.4 months, MK+ and 3 abnormalities: 8.0 months, MK+ and 4 abnormalities: 7.9 months and MK+ and ≥ 5 abnormalities: 4.9 months; P<0.01). In multivariate analyses, MK was not an independent prognostic factor. Our data support the hypothesis that a high number of complex abnormalities, associated with an instable clone, define the subgroup with the worst prognosis in MDS, independent of MK.

Abstract
Twenty-nine patients with brain metastases regardless of the origin were treated with the combination of 1-3-bis-(2-chloroethyl)-1-nitrosourea (BCNU), 120 mg/m2 i.v. every six weeks, and teniposide (VM26), 100 mg/m2 i.v. on the days 1 and 2 of every three-week period. Five objective responses were obtained (17%), four of them being partial and one complete. The latter was observed in a patient suffering from breast cancer, and still remains free of the disease after three years follow-up. The median survival time for the whole group is 14.6 weeks. Twelve more patients (41%) had symptomatic improvement related to chemotherapy. The treatment was well tolerated and only mild and reversible toxicity was observed. A global 58% (17% plus 41%) symptomatic improvement was observed.

Abstract
AIMS Assessment of effectiveness of a plan entitled «Smoke-free hospitals», specifically the reduction in the number of smoking staff and an increase in smoke-free areas. METHOD Interventional, non-controlled, populational study. A baseline study was conducted in 2004 to find out the situation as regards the prevalence of smokers in our hospital and the support of health workers for the smoke-free hospital plan. We used the questionnaire validated for the European smoke free hospital network in a sample of 483 workers randomly selected and stratified by gender, age and establishment. In 2007 we repeated the study with the same methodology to ascertain the progress of the project, in this case a sample of 425 workers was collected. RESULTS The number of smoking workers had decreased from 35.2% to 27.4 (P<.05). This reduction was seen in virtually all sectors, but was less so in nursing staff. In 2007 we had achieved that people only smoke in smoking areas (P<.0001). The plan was supported by smokers and non-smokers. CONCLUSIONS The «Smoke-free hospital» plan has achieved the objectives proposed. The actions carried out helped to enforce the law and respect that hospital areas should not be for smoking, together with strong support to help workers who want to quit smoking are shown to be effective.

Abstract
INTRODUCTION Stroke is one of the main causes of morbidity and mortality in developed countries today. Smoking is a risk factor that is associated with arteriosclerotic disease. AIM To evaluate the risk of having a stroke associated to both active and passive smoking in a case-control study. PATIENTS AND METHODS A case-control study was conducted which included 151 stroke patients who were admitted to hospital in the Neurology Service at the Hospital General Universitario in Alicante over a 12-month period. The control group (302) was obtained from patients who visited the emergency department at the hospital with no history of strokes and who reported clinical signs and symptoms that were not compatible with a stroke. The cases and controls were paired according to age and sex, including two controls of the same sex and whose ages were within a year of that of each case which was obtained. RESULTS The mean age of the patients was 70.6 years (range: 59-81 years). Males predominated in the sample (57.6%). Stroke patients had a significantly higher percentage of hypertension, peripheral arterial disease, heart disease and dyslipidemia than the control group. The most frequently affected vascular territory was the carotid (33.8%). The most frequent presenting symptom of the stroke was motor syndrome together with language disorders (39.4%). The risk of suffering a stroke associated to active smoking was 1.40 (CI 95% = 0.91-2.15) and in the case of passive smoking it was 1.45 (CI 95% = 0.82-2.58). CONCLUSIONS The findings from this study suggest there is a relevant association between environmental exposure to tobacco smoke and increased vascular risk (which confirms other results that have been published in the literature) and stress how important it is for non-smokers to find smoke-free zones.

Abstract
6012 Background: Cetuximab and paclitaxel have shown to be active in SCCHN pts and preclinical data has demonstrated a possible synergy for the combination. In a variety of tumor types, weekly paclitaxel has demonstrated an improved safety profile and activity as compared to every 3 weeks paclitaxel, providing the rationale to study the combination of cetuximab and weekly paclitaxel in metastatic/recurrent SCCHN. Methods: Pts were required to have a y performance status (KPS) = 70%, measurable disease using RECIST criteria, and may have received one regimen of induction and/or concomitant chemotherapy, but not within the recurrent/metastatic setting. Treatment included weekly paclitaxel 80 mg/m2 and cetuximab (initial dose of 400 mg/m2, followed by a weekly infusion of 250 mg/m2). Biopsies of tumors and samples of blood are being analyzed for correlative markers including EGFR gene copy number -FISH-, polymorphisms of intron 1 of the EGFR, and downstream EGFR pathway markers and mutations. Results: 46 planned pts were enrolled from Ap-2006 to Sep-2006. Median age is 60 years (range 42–78). Median KPS is 80% (range 70–100%). 35 pts are evaluable for response. Complete responses have been observed in 7 pts, partial responses in 18 pts, and stable disease in 6 pts for an overall response rate of 71% and disease control rate of 88%. 44 pts are evaluable for safety. Main grade 3/4 toxicities(NCI): 8 pts had acne- like rash; 7 neutropenia but only 1 febrile neutropenia; 6 asthenia; 3 mucositis; 2 infusion related reactions to paclitaxel and 1 to cetuximab; 2 peripheral neuropathies; 1 diarrhea; 1 vomiting; and 1 conjunctivitis. Conclusions: This trial shows that the combination of cetuximab and weekly paclitaxel is well tolerated and provides very encouraging activity in advanced/recurrent SCCHN. The full data, including biomarker results, will be presented at the annual meeting. No significant financial relationships to disclose.

Abstract
5515 Background: we have previously reported that ICT plus CRT is more active than CRT alone in pts with unresectable LAHNC (Hitt et al: ASCO 2005, abstract 5578). Here we present new data of efficacy and time to progression (TTP) in this trial. Methods: Patients: eligible pts included those with unresectable LAHNC, measurable disease, adequate organ function and ECOG 0–1. Pts were stratified according to primary tumor site. Treatment: Induction chemotherapy regimens (3 cycles): PF : P 100 mg/m2 day (d) 1, then F 1000 mg/m2 c.i. d1–5 q 21d; TPF: T 75 mg/m2 d1, P 75 mg/m2 d1, F 750 mg/m2 c.i. d 1–5 q 21 d plus G-CSF and ciprofloxacin. Chemoradiotherapy: conventional RT up to 70 Gy plus P 100 mg/m2 d 1–22–43 Results: Patients: a total of 310 pts have been accrued. Pts/tumor characteristics (ECOG, age, primary site, T/N stage) were well balanced among the three arms. T/N stage: T3–4 (88%); N2–3 (63%); pharynx-oropharynx site (62%). Treatment: Median number of cycles of ICT: 3; median dose of RT: 70 Gy, median number of cycles of P during RT in three arms: 3. Efficacy: Complete Response: 70% (ICT + CRT) vs. 49% (CRT alone) (p = 0.01). The response rate was similar between TPF and PF. Time to progression (TTP) in months: 16 (TPF + CRT); 12 (PF + CRT) vs 8 (CRT alone) (log-Rank= 0.02). G 3/4 toxicity (NCI criteria): Febrile neutropenia: 21% (TPF); mucositis: 10% (PF). Mucositis was observed in 55% (TPF + CRT), 60% (PF + CRT) and 36% (CRT alone) of the pts, respectively Conclusions: The results of the present randomised clinical trial demonstrate that the combination of ICT + CRT significantly increases the complete response rate and prolongs TTP when compared to CRT alone in patients with unresectable LAHNC. No significant financial relationships to disclose.

Abstract
BACKGROUND The International Prognostic Index (IPI), initially designed for aggressive lymphomas, is also used in follicular lymphoma (FL) and other indolent lymphomas. Two new prognostic indexes have recently been proposed for FL [the Italian Lymphoma Intergroup (ILI) Index and the Follicular Lymphoma International Prognostic Index (FLIPI)]. PATIENTS AND METHODS Three indexes, IPI [age >60 years, extranodal involvement two or more sites, elevated lactate dehydrogenase (LDH), Eastern Cooperative Oncology Group performance status > or =2, stage > or =3], ILI (age >60 years, extranodal involvement two or more sites, elevated LDH, male sex, B symptoms, erythrocyte sedimentation rate > or =30 mm first hour) and FLIPI (age >60 years, stage > or =3, elevated LDH, nodal involvement five or more, haemoglobin level < or =12 g/dl) were calculated in 411 patients with FL. RESULTS Overall concordance between the three indexes was 54%. A total of 126 (31%) patients were included in the high-risk group according to IPI, 131 (32%) according to ILI and 157 (38%) after FLIPI application. Ten-year overall survival rates after applying the prognostic indexes (IPI, ILI and FLIPI) were, respectively: 72%, 71% and 72%, in the low-risk group; 51%, 60% and 49% in the intermediate-risk group; and 24%, 16% and 31% in the high-risk group. CONCLUSIONS In this series, all three indexes, IPI, ILI and FLIPI, were useful to classify FL patients into differentiated risk groups, although the FLIPI identified a larger proportion of high-risk patients than the IPI and ILI.

Abstract
MOTIVATION We propose a new class of variable-order Bayesian network (VOBN) models for the identification of transcription factor binding sites (TFBSs). The proposed models generalize the widely used position weight matrix (PWM) models, Markov models and Bayesian network models. In contrast to these models, where for each position a fixed subset of the remaining positions is used to model dependencies, in VOBN models, these subsets may vary based on the specific nucleotides observed, which are called the context. This flexibility turns out to be of advantage for the classification and analysis of TFBSs, as statistical dependencies between nucleotides in different TFBS positions (not necessarily adjacent) may be taken into account efficiently--in a position-specific and context-specific manner. RESULTS We apply the VOBN model to a set of 238 experimentally verified sigma-70 binding sites in Escherichia coli. We find that the VOBN model can distinguish these 238 sites from a set of 472 intergenic 'non-promoter' sequences with a higher accuracy than fixed-order Markov models or Bayesian trees. We use a replicated stratified-holdout experiment having a fixed true-negative rate of 99.9%. We find that for a foreground inhomogeneous VOBN model of order 1 and a background homogeneous variable-order Markov (VOM) model of order 5, the obtained mean true-positive (TP) rate is 47.56%. In comparison, the best TP rate for the conventional models is 44.39%, obtained from a foreground PWM model and a background 2nd-order Markov model. As the standard deviation of the estimated TP rate is approximately 0.01%, this improvement is highly significant.

Abstract
BACKGROUND We report our experience in the study of antiganglioside antibodies and define their clinical value establishing associations between clinical syndromes and immunological findings. METHODS We analysed 275 sera: Guillain-Barré syndrome (GBS) (78), Miller-Fisher syndrome (MFS) (37), chronic inflammatory demyelinating polyneuroapthy (CIDP) (17), multifocal motor neuropathy (NMM) (42), chronic axonal mixed polyneuropathy (PNP) (54), amyotrophic lateral sclerosis (ALS) (28) and lower motor neuron disease (LMND) (17). We have studied the presence of IgG and IgM antibodies to 9 gangliosides using ELISA and TLC. RESULTS We have detected anti-GQ1b antibodies in 36/37 (97,3%) of patients with MFS, being undetectable after 4 weeks in 83%. A 34 % (26/78) of patients with GBS were positive for several antiganglioside specificities being GalGalNAc the most frequent (54%). Two out of three sera positive for GD1a corresponded to axonal Guillain-Barré. IgM class anti-GM1 antibodies were positive in 10/12 patients with MMN, while only a 3-9% of patients with ALS, CIDP, PNP and LMND presented antiganglioside antibodies. CONCLUSIONS Analysis of anti-GQ1b antibodies confirms the diagnosis of MFS, excluding other acute brainstem pathologies and, in this study, detection of anti-GD1a antibodies indicates axonal damage in GBS and suggest a worse prognosis. IgM anti-GM1 antibodies are only found in MMN. These findings confirm a disease specific correlation between specific neuropathies and antiganglioside antibodies clinically useful.

Abstract
BACKGROUND To analyse the etiology, diagnostic methods and response to therapy in 30 episodes of pneumonia diagnosed in 17 patients with chronic lymphocytic leukemia (CLL) between 1995 and 2000. PATIENTS AND METHOD In each episode of pneumonia the following data were analysed: age, gender, treatment of CLL, antiinfectious prophylaxis, granulocytopenia, CD4/CD8 lymphocytes ratio, hipogammaglobulinemia, origin of pneumonia (nosocomial or community-acquired), localisation, respiratory insufficiency, need for mechanical ventilation, antimicrobial therapy and response. Diagnostic methods included blood and sputum cultures, fiberoptic bronchoscopy and search for antigens in urine (Legionella pneumophila serogroup 1, galactomannan, and Streptococcus pneumoniae). RESULTS Median age of the series was 60 yr. (range 50-86) and 12 patients were male. Chlorambucil and prednisone were used in 13 cases and fludarabine in 8. Granulocytopenia was present in 14 episodes, hypogammaglobulinemia was seen in 22 and CD4/CD8 ratio was lower than 1 in 8 out of 14 evaluable cases. Etiology of pneumonia was established in 16 episodes (53%). Fiberoptic bronchoscopy was the most useful technique (83% of positive diagnoses) followed by blood cultures (38%). Two patients were diagnosed of aspergillosis at autopsy. Pneumococcus was the most frequent agent (5 cases) followed by Pseudomonas aeruginosa (4), Pneumocystis carinii (2) and Aspergillus fumigatus (2). One out of the two patients with P. carinii pneumonia had received fludarabin and the remaining was treated with prednisone for long time. Ten patients (30%) had died: P. aeruginosa (3 cases), P. carinii (2), A. fumigatus (2), Mycobacterium xenopi (1), and unknown microorganism (2). CONCLUSIONS In this series of CLL patients the frequency of etiologic diagnosis of pneumonias was good. Pneumococcus was the most frequent microorganism. Pneumonias caused by opportunistic microorganisms were associated to the treatment with fludarabin or prednisone and were associated to a high mortality rate.

Abstract
BACKGROUND To analyse the results of the treatment with 2-chlorodeoxyadenosine (2CdA) in 9 patients with refractory or relapsed Langerhans cell histiocytosis (LCH) tracted in 8 Spanish hospitals between 1993 and 1999. PATIENTS AND METHOD In the 9 patients the following data were recorded: age, sex, organ involvement by LCH, first treatment and response, dose, number of cycles and schedule of administration 2CdA, response to 2CdA treatment, toxicity, disease-free survival (DFS) and overall survival (OS). RESULTS Median age was 25 years (range, 6-63). All patients had multiorganic involvement by LCH, with severe organ dysfunction in 4. 2CdA was administered as second line treatment in 7 cases and as third line in 2. The 2CdA dose was 0.1 mg/kg per day during 5 days in the majority of patients, and interval between cycles was 4 weeks. In 2 cases a complete remission (CR) was achieved and 4 cases attained a partial remission (PR) (overall response rate 66%). The main toxicity was hematologic, with neutropenia grade > 2 in 5 cases and thrombocytopenia > 2 in 5. Four patients had infections, with fatal evolution in one of them. After a median follow-up of 8 months (range 2-17), 2 patients remained in CR (12 months both), 4 in PR (range 2-12 months) and one had active disease (17 months). The other two died due to progressive disease and Aspergillus spp. sepsis, respectively. The actuarial probabilities of DFS and OS were 58% (95% CI, 38-78%) and 71% (95% CI, 54-88%), respectively. CONCLUSIONS 2CdA is an active drug for patients with refractory or relapsed LCH, and its main toxicity is myelosuppression. The usefulness of 2CdA, isolated or in combination with other drugs, in patients with refractory or relapsed LCH must be assessed in controlled studies.

Abstract
The recognition of the fundamental role of the spleen in the immune response has led to greater efforts to preserve the spleen after injury. Whenever possible, splenic preservation is the preferred treatment modality for both blunt and penetrating injuries. The past 2 decades have seen an evolution in the way this goal is accomplished. Operative splenic preservation achieved by splenorrhaphy as the most prevalent method for the management of splenic trauma has progressed to the nonoperative management of these injuries. The factor most responsible for bringing about this change has been the development of more sophisticated and accurate imaging techniques in the evaluation of these patients. Splenectomy should be avoided whenever possible, as the procedure continues to be associated with excessive transfusion requirements and increased postoperative sepsis rates.

Abstract
BACKGROUND In spite of not being considered as an AIDS defining illness, Hodgkin's disease (HD) has specific clinical and biological features in HIV-infected patients. PATIENTS AND METHODS Study of clinicopathologic and analytic characteristics, Epstein-Barr virus (EBV) detection (polymerase chain reaction), and prognosis in 15 patients with HD and HIV infection. RESULTS Thirteen patients had B symptoms, 10 extranodal involvement and 12 advanced HD. The most frequent histologic subtypes were mixed cellularity (6) and lymphocyte depletion (6). The mean (SD) of CD4 lymphocytes was 0.10 (0.08) x 10(9)/l. The presence of EBV in lymph node biopsy was demonstrated in 3 out of 4 patients investigated. Complete remission (CR) was achieved in 7 out of 14 treated cases (50%), the median overall survival was 26 months and the 2 year event-free survival probability was 60%. CONCLUSIONS In HIV-infected patients, HD presents in advanced stages, unfavourable histologic subtypes, frequent extranodal involvement and B symptoms. The prognosis is poor, mainly because of a low CR rate.

Abstract
Jeder Botaniker, der sich mit der Artenvielfalt beschäftigt, träumt davon, neue Arten zu entdecken. Die Meinung, dies sei heute nur noch im Reichtum des tropischen Regenwalds möglich, trügt. Auch die Trockengebiete der Erde bergen noch eine Fülle unentdeckter Schätze, die allerdings nicht zu jeder Zeit sichtbar sind.

Abstract
BACKGROUND The aim of this study was the assessment of the scientific production and impact on academic and/or hospital promotion ob sabbatical leaves of medical staff from a University hospital. POPULATION AND METHODS A matched case-control design was used. The Mantel-Haenszel odds ratio (ORMH) and its 95% confidence intervals were calculated. A total of 52 sabbaticals leaves were analyzed with successful matching for 43 pairs. RESULTS AND CONCLUSIONS Taking a sabbatical leaves is associated with a significant higher chance of hospital promotion (ORMH = 7.5; CI 95%, 1.71-32.78; o = 0.004), but there is not a significantly higher chance of academic promotion (ORMH = 0.66; CI del 95%, 0.23-1.83; p = 0.60).
