Abstract
BACKGROUND Previous literature supports exercise as a preventative agent for prenatal depression; however, treatment effects for women at risk for prenatal depression remain unexplored. The purpose of the study was to examine whether exercise can lower depressive symptoms among women who began pregnancy at risk for depression using both a statistical significance and reliable and clinically significant change criteria. METHODS This study is a secondary analysis of two randomized controlled trials that followed the same exercise protocol. Pregnant women were allocated to an exercise intervention group (IG) or control group (CG). All participants completed the Center for Epidemiological Depression (CES-D) scale at gestational week 9-16 and 36-38. Women with a baseline score ⩾16 were included. A clinically reliable cut-off was calculated as a 7-point change in scores from pre- to post-intervention. RESULTS Thirty-six women in the IG and 25 women in the CG scored ⩾16 on the CES-D at baseline. At week 36-38 the IG had a statistically significant lower CES-D score (14.4 ± 8.6) than the CG (19.4 ± 11.1; p < 0.05). Twenty-two women in the IG (61%) had a clinically reliable decrease in their post-intervention score compared to eight women in the CG (32%; p < 0.05). Among the women who met the reliable change criteria, 18 (81%) in the IG and 7 (88%) in the CG had a score <16 post-intervention, with no difference between groups (p > 0.05). CONCLUSIONS A structured exercise program might be a useful treatment option for women at risk for prenatal depression.

Abstract
OBJECTIVES To identify if maternal educational attainment is a prognostic factor for gestational weight gain (GWG), and to determine the differential effects of lifestyle interventions (diet based, physical activity based or mixed approach) on GWG, stratified by educational attainment. DESIGN Individual participant data meta-analysis using the previously established International Weight Management in Pregnancy (i-WIP) Collaborative Group database (https://iwipgroup.wixsite.com/collaboration). Preferred Reporting Items for Systematic reviews and Meta-Analysis of Individual Participant Data Statement guidelines were followed. DATA SOURCES Major electronic databases, from inception to February 2017. ELIGIBILITY CRITERIA Randomised controlled trials on diet and physical activity-based interventions in pregnancy. Maternal educational attainment was required for inclusion and was categorised as higher education (≥tertiary) or lower education (≤secondary). RISK OF BIAS Cochrane risk of bias tool was used. DATA SYNTHESIS Principle measures of effect were OR and regression coefficient. RESULTS Of the 36 randomised controlled trials in the i-WIP database, 21 trials and 5183 pregnant women were included. Women with lower educational attainment had an increased risk of excessive (OR 1.182; 95% CI 1.008 to 1.385, p =0.039) and inadequate weight gain (OR 1.284; 95% CI 1.045 to 1.577, p =0.017). Among women with lower education, diet basedinterventions reduced risk of excessive weight gain (OR 0.515; 95% CI 0.339 to 0.785, p = 0.002) and inadequate weight gain (OR 0.504; 95% CI 0.288 to 0.884, p=0.017), and reduced kg/week gain (B -0.055; 95% CI -0.098 to -0.012, p=0.012). Mixed interventions reduced risk of excessive weight gain for women with lower education (OR 0.735; 95% CI 0.561 to 0.963, p=0.026). Among women with high education, diet based interventions reduced risk of excessive weight gain (OR 0.609; 95% CI 0.437 to 0.849, p=0.003), and mixed interventions reduced kg/week gain (B -0.053; 95% CI -0.069 to -0.037,p<0.001). Physical activity based interventions did not impact GWG when stratified by education. CONCLUSIONS Pregnant women with lower education are at an increased risk of excessive and inadequate GWG. Diet based interventions seem the most appropriate choice for these women, and additional support through mixed interventions may also be beneficial.

Abstract
BACKGROUND Diet- and physical activity-based interventions in pregnancy have the potential to alter maternal and child outcomes. OBJECTIVES To assess whether or not the effects of diet and lifestyle interventions vary in subgroups of women, based on maternal body mass index (BMI), age, parity, Caucasian ethnicity and underlying medical condition(s), by undertaking an individual patient data (IPD) meta-analysis. We also evaluated the association of gestational weight gain (GWG) with adverse pregnancy outcomes and assessed the cost-effectiveness of the interventions. DATA SOURCES MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Database of Abstracts of Reviews of Effects and Health Technology Assessment database were searched from October 2013 to March 2015 (to update a previous search). REVIEW METHODS Researchers from the International Weight Management in Pregnancy Collaborative Network shared the primary data. For each intervention type and outcome, we performed a two-step IPD random-effects meta-analysis, for all women (except underweight) combined and for each subgroup of interest, to obtain summary estimates of effects and 95% confidence intervals (CIs), and synthesised the differences in effects between subgroups. In the first stage, we fitted a linear regression adjusted for baseline (for continuous outcomes) or a logistic regression model (for binary outcomes) in each study separately; estimates were combined across studies using random-effects meta-analysis models. We quantified the relationship between weight gain and complications, and undertook a decision-analytic model-based economic evaluation to assess the cost-effectiveness of the interventions. RESULTS Diet and lifestyle interventions reduced GWG by an average of 0.70 kg (95% CI -0.92 to -0.48 kg; 33 studies, 9320 women). The effects on composite maternal outcome [summary odds ratio (OR) 0.90, 95% CI 0.79 to 1.03; 24 studies, 8852 women] and composite fetal/neonatal outcome (summary OR 0.94, 95% CI 0.83 to 1.08; 18 studies, 7981 women) were not significant. The effect did not vary with baseline BMI, age, ethnicity, parity or underlying medical conditions for GWG, and composite maternal and fetal outcomes. Lifestyle interventions reduce Caesarean sections (OR 0.91, 95% CI 0.83 to 0.99), but not other individual maternal outcomes such as gestational diabetes mellitus (OR 0.89, 95% CI 0.72 to 1.10), pre-eclampsia or pregnancy-induced hypertension (OR 0.95, 95% CI 0.78 to 1.16) and preterm birth (OR 0.94, 95% CI 0.78 to 1.13). There was no significant effect on fetal outcomes. The interventions were not cost-effective. GWG, including adherence to the Institute of Medicine-recommended targets, was not associated with a reduction in complications. Predictors of GWG were maternal age (summary estimate -0.10 kg, 95% CI -0.14 to -0.06 kg) and multiparity (summary estimate -0.73 kg, 95% CI -1.24 to -0.23 kg). LIMITATIONS The findings were limited by the lack of standardisation in the components of intervention, residual heterogeneity in effects across studies for most analyses and the unavailability of IPD in some studies. CONCLUSION Diet and lifestyle interventions in pregnancy are clinically effective in reducing GWG irrespective of risk factors, with no effects on composite maternal and fetal outcomes. FUTURE WORK The differential effects of lifestyle interventions on individual pregnancy outcomes need evaluation. STUDY REGISTRATION This study is registered as PROSPERO CRD42013003804.

Abstract
PURPOSE This study aimed to compare the cross-sectional results from three experimental studies conducted on land, in water, and in mixed form (land + water) during pregnancy on maternal and newborn outcomes. METHODS A cross-sectional design was used to analyze the results of three randomized clinical trials in healthy pregnant women from Madrid (Spain) and Buenos Aires (Argentina). Five hundred and sixty-eight pregnant women were recruited. For each of the studies, the number of women in the exercise group totaled 107 for study 1 (land), 49 women for study 2 (water), and 101 women for study 3 (land + water). A total of 311 women represented the control group (CG) (pooled together from all three studies). RESULTS Total maternal weight gain was different between study 1 and CG (11.7 vs 13.4 kg, P = 0.001, Cohen's d = 0.38) as well as the percentage of pregnant women with excessive weight gain (20.6%, n = 22, vs 37.9%, n = 118, respectively, P = 0.005, χ = 16.6, OR = 0.42, 95% confidence interval = 0.25-0.71). The number of pregnant women with gestational diabetes in CG was significantly higher than that in studies 2 and 3 (CG n = 22/7.1%; study 2, n = 0/0%; and study 3, n = 1/1%; P = 0.03, χ = 8.9). CONCLUSION Exercise performed on land is more effective than aquatic activities in preventing excessive maternal weight gain, whereas combined programs (land + aquatic) or water exercise programs may be more effective in preventing gestational diabetes.

Abstract
PURPOSE The aim of the present study was to examine the influence of a supervised and regular program of aquatic activities throughout gestation on maternal weight gain and birth weight. DESIGN A randomized clinical trial. SETTING Instituto de Obstetricia, Ginecología y Fertilidad Ghisoni (Buenos Aires, Argentina). PARTICIPANTS One hundred eleven pregnant women were analyzed (31.6 ± 3.8 years). All women had uncomplicated and singleton pregnancies; 49 were allocated to the exercise group (EG) and 62 to the control group (CG). INTERVENTION The intervention program consisted of 3 weekly sessions of aerobic and resistance aquatic activities from weeks 10 to 12 until weeks 38 to 39 of gestation. MEASURES Maternal weight gain, birth weight, and other maternal and fetal outcomes were obtained by hospital records. ANALYSIS Student unpaired t test and χ2 test were used; P values ≤.05 indicated statistical significance. Cohen's d was used to determinate the effect size. RESULTS There was a higher percentage of women with excessive maternal weight gain in the CG (45.2%; n = 28) than in the EG (24.5%; n = 12; odds ratio = 0.39; 95% confidence interval: 0.17-0.89; P = .02). Birth weight and other pregnancy outcomes showed no differences between groups. CONCLUSION Three weekly sessions of water activities throughout pregnancy prevents excessive maternal weight gain and preserves birth weight.

Abstract
CONTEXT Interventions targeting maternal obesity are a healthcare and public health priority. OBJECTIVE The objective of this review was to evaluate the adequacy and effectiveness of the methodological designs implemented in dietary intervention trials for obesity in pregnancy. DATA SOURCES A systematic review of the literature, consistent with PRISMA guidelines, was performed as part of the International Weight Management in Pregnancy collaboration. STUDY SELECTION Thirteen randomized controlled trials, which aimed to modify diet and physical activity in overweight and obese pregnant women, were identified. DATA SYNTHESIS There was significant variability in the content, delivery, and dietary assessment methods of the dietary interventions examined. A number of studies demonstrated improved dietary behavior in response to diet and/or lifestyle interventions. Nine studies reduced gestational weight gain. CONCLUSION This review reveals large methodological variability in dietary interventions to control gestational weight gain and improve clinical outcomes in overweight and obese pregnant women. This lack of consensus limits the ability to develop clinical guidelines and apply the evidence in clinical practice.

Abstract
BACKGROUND The prevalence of all pregnancies with some form of hypertension can be up to 10%, with the rates of diagnosis varying according to the country and population studied and the criteria used to establish the diagnosis. Prepregnancy obesity and excessive gestational weight gain (GWG) of all body mass index (BMI) categories have been associated with maternal hypertensive disorders and linked to macrosomia (>4000 g) and low birthweight (<2500 g). No large randomized controlled trial with high adherence to an exercise program has examined pregnancy-induced hypertension and these associated issues. We investigated whether women adherent (≥80% attendance) to an exercise program initiated early showed a reduction in pregnancy-induced hypertension and excessive GWG in all prepregnancy BMI categories, and determined if maternal exercise protected against macrosomia and low birthweight. OBJECTIVE We sought to examine the impact of a program of supervised exercise throughout pregnancy on the incidence of pregnancy-induced hypertension. STUDY DESIGN A randomized controlled trial was used. Women were randomized into an exercise group (N = 382) or a control group (N = 383) receiving standard care. The exercise group trained 3 d/wk (50-55 min/session) from gestational weeks 9-11 until weeks 38-39. The 85 training sessions involved aerobic exercise, muscular strength, and flexibility. RESULTS High attendance to the exercise program regardless of BMI showed that pregnant women who did not exercise are 3 times more likely to develop hypertension (odds ratio [OR], 2.96; 95% confidence interval [CI], 1.29-6.81, P = .01) and are 1.5 times more likely to gain excessive weight if they do not exercise (OR, 1.47; 95% CI, 1.06-2.03, P = .02). Pregnant women who do not exercise are also 2.5 times more likely to give birth to a macrosomic infant (OR, 2.53; 95% CI, 1.03-6.20, P = .04). CONCLUSION Maternal exercise may be a preventative tool for hypertension and excessive GWG, and may control offspring size at birth while reducing comorbidities related to chronic disease risk.

Abstract
OBJECTIVE To understand what evidence exists with regard to maternal and offspring benefits of aerobic and/or resistance training during pregnancy. METHODS Systematic review of RCTs (published until May 2015) with healthy pregnant women and focusing on the benefits of exercise interventions on maternal health or perinatal outcomes. Studies were ranked as high/low quality, and a level of evidence was established according to the number of high-quality studies and consistency of the results. RESULTS 61 RCTs were analyzed. The evidence for a benefit of combined exercise [aerobic+resistance (muscle strength)] interventions on maternal cardiorespiratory fitness and prevention of urinary incontinence was strong. A weak or insufficient level of evidence was found for the rest of interventions and outcomes CONCLUSION The exercise modality that seems to induce a more favorable effect on maternal health is the combination of aerobic and resistance exercises during pregnancy.

Abstract
Purpose. The aim of the present study was to examine the influence of moderate physical exercise throughout pregnancy on the duration of labor stages. Design. Study was a randomized controlled trial. Setting. The study took place at Hospital Puerta de Hierro and Hospital Severo Ochoa in Madrid, Spain. Subjects. We examined 166 pregnant women (31.6 ± 3.8 years), and all had uncomplicated and singleton gestation. Of these 83 were allocated to the exercise group (EG) and 83 to the control group (CG). Intervention. Women from the EG participated in a physical conditioning program throughout pregnancy, which included 55- to 60-minute sessions, 3 days per week. Measures. Pregnancy outcomes were measured: duration of labor stages, gestational age, weight gain, type of delivery, birth weight, birth size, head circumference, Apgar score, pH of umbilical cord. Analysis. Student's unpaired t-tests and χ2 tests were used; p values of < .05 indicated statistical significance. Cohen's d was used to determine the effect size. Results. Significant differences were found in the duration of the first stage of labor (EG = 389.6 ± 347.64 minutes vs. CG = 515.72 ± 353.36 minutes; p = .02, effect size Cohen's d = .36). The second and third stages did not differ between the study groups. Conclusion. A physical exercise program during pregnancy is associated with a shorter first stage of labor. These results may have important relevance to public health.

Abstract
Pregnancy is a time in women’s lives that is associated with considerable physiological and psychological changes. From a scientific point of view, practically all the female body is changing for nine months, sometimes discontinuously, which can cause generate alterations, including psychological. The addition of exercise can generate, in theory, conflicts due to the requirements and reactions of the physical activity itself. Both pregnancy and exercise are biological process which involve striking many adaptations, such adaptations may be in the same or in opposite direction. Depending on the specific variable being studied. The scientific literature has not been totally conclusive regarding the coexistence of two processes: exercise and pregnancy. However there is currently sufficient empirical evidence to support the promotion of moderate prenatal physical activity for maternal health benefits. Most of the studied consulted in this review show that in the absence of obstetric contraindication during pregnancy adding physical exercise should not pose a risk to maternal and fetal well-being.

Abstract
Purpose. The aim of the present study was to examine the influence of a program of moderate physical exercise throughout pregnancy on maternal and fetal parameters. Design. The study design was a randomized controlled trial. Setting. The study took place at the Hospital of Fuenlabrada in Madrid, Spain. Sample. Analyzed were 200 pregnant women (31.54 ± 3.86 years), all of whom had uncomplicated and singleton gestation. Of these subjects, 107 were allocated to the exercise group (EG) and 93 to the control group (CG). Intervention. Women from EG participated in a physical conditioning program throughout pregnancy, which included a total of 55- to 60-minute weekly sessions, 3 days per week. Measures. Pregnancy outcomes. Maternal: gestational age, weight gain, type of delivery, blood pressure during pregnancy, gestational diabetes (n/%). Fetal: birth weight, birth size, head circumference, Apgar score, pH of umbilical cord. Analysis. Student's unpaired t-test and χ2 test were used; p values of ≤ .05 indicated statistical significance. Cohen's d was used to determine the effect size. Results. There were significantly more pregnant women in the CG who gained excessive weight during their pregnancies than in the EG group (CG: N = 31, 35.6% versus N = 22, 21.2%; χ2 = 4.95; p =.02). The effect size was small (Phi value =.16). Other pregnancy outcome showed no differences between groups. Conclusion. A regular and moderate physical exercise program throughout pregnancy is not a risk to maternal and fetal well-being, and it helps to control excessive weight gain.

Abstract
Recent studies have estimated the prevalence of depression during pregnancy to be between 10% and 30%, which is higher than that in the postpartum period. Pharmacological treatment during pregnancy is difficult because of the possible side effects of antidepressants on the mother and the fetus. The aim of this study was to examine whether a supervised exercise program (EP) reduces depressive symptoms in pregnant women. A randomized controlled trial was designed. One hundred eighty four healthy pregnant women from Fuenlabrada Hospital were included (31.37 ± 3.62 years). Women from the exercise group (EG) participated in a supervised EP consisting of three, 55- to 60-min sessions per week throughout pregnancy. The main outcome measure was the patients’ depression level assessed by means of the Center for Epidemiologic Studies Depression Scale (CES-D). A total of 167 pregnant women were analyzed; 90 were allocated to the EG and 77 to the control group (CG). Significant differences were found between groups at the end of the study in CES-D scores (EG: 7.67 ± 6.30 vs. CG: 11.34 ± 9.74, p = .005) and in percentages of pregnant women depressed (EG: n = 11/12.2% vs. CG: n = 19/24.7%, p = .04). Our results show that supervised physical exercise during pregnancy reduces the level of depression and its incidence in pregnant women.

Abstract
OBJECTIVE To study the effect on maternal weight gain of a supervised light- to moderate-intensity exercise-based intervention performed from the ninth week of pregnancy. PARTICIPANTS AND METHODS A total of 962 healthy pregnant women were randomly assigned to a standard care or exercise intervention group conducted between September 1, 2007, and January 31, 2011. The intervention included light- to moderate-intensity aerobic and resistance exercises performed 3 days a week (50-55 minutes per session). Excessive gestational weight gain was calculated on the basis of the 2009 Institute of Medicine (IOM) recommendations. Gestational body weight gain was calculated on the basis of the weight measured at the first prenatal visit (fifth to sixth weeks of gestation) and weight measured at the last visit to the clinic before delivery. Women were categorized into normal weight or overweight or obese. RESULTS Women in the intervention group gained less weight (adjusted mean difference, 1.039 kg; 95% CI, 0.534-1.545 kg; P<.001) and were less likely to gain weight above the IOM recommendations (odds ratio, 0.625; 95% CI, 0.461-0.847) compared with those in the standard care group. The main treatment effects according to body mass index category were that normal weight women in the intervention group gained less weight (adjusted mean difference, 1.393 kg; 95% CI, 0.813-1.972 kg; P<.001) and were less likely to gain weight above the IOM recommendations (odds ratio, 0.508; 95% CI, 0.334-0.774) than normal weight women who received standard care. No significant treatment effect was observed in overweight or obese women. CONCLUSION Supervised exercise of light to moderate intensity can be used to prevent excessive gestational weight gain, especially in normal weight women.

Abstract
The ALICE Collaboration has studied J/ψ production in pp collisions at √s=7 TeV at the LHC through its muon pair decay. The polar and azimuthal angle distributions of the decay muons were measured, and results on the J/ψ polarization parameters λ(θ) and λ(φ) were obtained. The study was performed in the kinematic region 2.5<y<4, 2<p(t)<8 GeV/c, in the helicity and Collins-Soper reference frames. In both frames, the polarization parameters are compatible with zero, within uncertainties.

Abstract
3005 Background: T-cell and antibody responses to self antigens on cancer are usually constrained by immunologic tolerance and ignorance. We found that DNA vaccines encoding xenogeneic differentiation antigens, such as tyrosinase (TYR), can mediate tumor protection and regression in implantable mouse models and dogs with spontaneously arising melanoma. Based on this, we conducted a trial of DNA vaccines encoding mouse and human TYR in patients with AJCC stage III/IV melanoma. Methods: HLA-A*0201+ melanoma patients were randomized to 2 different schedules: one group received 3 injections of mouse TYR DNA followed by 3 injections of human TYR DNA while the other group received 3 injections of human TYR DNA followed by 3 injections with the mouse gene. The study was conducted a three different dose levels: 100, 500 and 1,500 mcg DNA/injection, administered IM every 3 weeks. A total of 18 patients were treated, 6 at each dose level being randomized to one of the two schedules. Anti-TYR antibodies and CD8+ T cells recognizing the native human tyrosinase369-377 (YMDGTMSQV) peptide were measured at fixed time points. T-cell responses were monitored with MHC tetramer and intracytoplasmic IFN-γ staining assays using 10-day in vitro stimulation. Multiparametric flow cytometry was performed to further define the phenotype of responding cells. Results: Most toxicities were transient grade I injection site reactions. Seven patients had CD8+ T cell responses, defined as a >3 standard deviation increase in baseline reactivity to the TYR peptide in either the tetramer or intracellular IFN-γ assay. There was no relationship between dose level or assigned schedule and occurrence of T-cell response. Phenotypic characterization of responding T cells showed that most were consistent with an effector memory phenotype including the expression of granzyme B and surface expression of CD107a. No antibody responses were observed. At a median of 42 months of follow-up, median survival has not been reached and 6/18 patients have died from melanoma (1 in the group of patients who had a T cell response and 5 in the non-responders). Conclusions: Mouse and human TYR DNA vaccines were safe and induced CD8+ T cell responses in 7/18 patients. T cells recognizing a native TYR peptide had a phenotype consistent with that of effector memory cells. No significant financial relationships to disclose.

Abstract
Patients with multiple myeloma (MM) refractory to chemotherapy can only benefit from supportive measures and have a very short survival. Thalidomide has recently shown antitumor activity in patients with refractory myeloma. Twenty-three patients (12 men and 11 women; median age, 72 years) with advanced MM were treated with thalidomide. Sixteen patients had refractory disease and seven had untested relapse. The median dose of thalidomide was 400 mg d (range, 200 to 800 mg/d). The drug was generally administered in two divided doses. Five patients required treatment discontinuation because of toxicity. Twelve of 23 patients (52%) responded. Three (13%) achieved a partial response, with greater than 50% reduction in serum monoclonal (M)-protein levels, and nine (39%) attained a minimal response, with a greater than 25% decrease in serum M-protein levels. No decrease in the size of soft tissue plasmacytomas was observed in six patients with extramedullary involvement.

Abstract
Thalidomide is active in patients with refractory myeloma. Seventeen patients (nine men/eight women, median age 73 years) with multiple myeloma (MM) were treated with thalidomide. Fifteen patients had refractory disease and two untested relapse. The median dose of thalidomide was 500 mg (range, 200-800 mg). Nine of the 17 patients (53%) responded. The response rate was significantly higher in patients with no extramedullary disease than in those with soft tissue masses (75% CI: 43-95% versus 0%; P = 0.01)). Of note, no decrease in the size of soft tissue plasmacytomas was observed in all the five patients who had extramedullary involvement. This data suggests that the mechanism of action and effectiveness of thalidomide might depend on the site of the tumour cells.

Abstract
The prognosis of patients relapsing after an autologous transplant (autoSCT) is very poor. Allogenic stem cell transplantation (alloSCT) offers the possibility of curing some of these patients, at the cost, however, of a high transplant related mortality (TRM). The aim of this study was to analyze the outcome of 14 consecutive patients with hematologic malignancies, from a single institution, who underwent alloSCT for progressive disease after autoSCT. Patients had relapsed at a median of 11.5 months (range 2-72) after autoSCT and they underwent alloSCT at a median of 25.5 months (range 7-73) from the first transplant. Ten patients received HLA-identical related peripheral blood progenitor cells, three patients underwent matched-unrelated donor marrow transplants, and one patient received a mismatched related transplant. Conditioning regimens consisted of total body irradiation plus cyclophosphamide (n=5) or melphalan (n=1), or high-dose combination chemotherapy (n=8). Cyclosporin A and methotrexate were administered as graft-versus-host disease (GVHD) prophylaxis. Eight patients (57%) developed grade II-IV acute GVHD. All evaluable patients (n=6) presented extensive chronic GVHD. Overall survival at 1 year was 16% (median 3.5 months, 95% CI 0.7-10.3). Ten patients (71%) died from transplant related complications at a median of 3.5 months (range 0.7-11). Only one patient died of recurrent disease. Three patients remain alive and in complete remission at the time of this report (4, 20 and 20 months, respectively). In conclusion, alloSCT offers the possibility of a sustained control of the disease in some patients who relapse after an autoSCT. However, the procedure is associated with a high transplant-related mortality. Better results might be obtained by carefully selecting patients and by reducing the intensity of the preparative regimen.

Abstract
BACKGROUND The current study was conducted to analyze the outcome and prognostic factors of patients with diffuse large B-cell lymphoma (DLCL) who did not achieve a complete response (CR) to first-line treatment. METHODS The current study was comprised of 83 patients (43 males and 40 females with a median age of 62 years) who did not achieve a CR (58 of whom had primary refractory disease and 25 of whom achieved a partial response) with initial treatment (doxorubicin-containing regimens in 87% of cases) from a series of 239 patients consecutively diagnosed with DLCL at a single institution. Initial variables, response to therapy, and salvage treatment were analyzed to predict survival. RESULTS Compared with patients who achieved a CR, nonresponders or partial responders more frequently were of advanced age and had a poor performance status (PS), B-symptoms, advanced stage of disease, bone marrow infiltration, increased serum lactate dehydrogenase, and a high-risk International Prognostic Index. Among the 58 patients with primary refractory disease, 18 died during initial treatment due to toxicity (14 patients) or disease progression (4 patients). The main variables predicting early death were a poor PS, age > 60 years, and an immunoblastic DLCL subtype. Twenty-five of these 58 patients were able to receive salvage regimens, with only 1 of them achieving a CR. The median survival for this group of patients was 10 months. With regard to those patients achieving a partial response, 18 of the 25 patients received further therapy with 28% of them achieving a CR. The median survival was 23 months. The degree of the response was found to be the only significant variable with which to predict survival, with 2-year survival rates of 4% and 40%, respectively, for patients with primary refractory disease and patients who achieved a partial response. CONCLUSIONS The prognosis of patients with primarily refractory DLCL is extremely unfavorable, whereas that of patients who achieve a partial response is slightly better. The inclusion of these patients in experimental trials is limited due to their tendency to be of an older age and to have a poor general status.

Abstract
Two patients with disseminated mantle-cell lymphoma relapsed 24 and 13 months, respectively, after high-dose chemotherapy and autologous stem cell transplantation (autoSCT). Both patients had an HLA-identical sibling and received an allogeneic stem cell transplant (alloSCT) 32 and 18 months after autologous transplant, after conditioning with fractionated 12 Gy total body irradiation plus cyclophosphamide 120 mg/kg. They are both alive and in complete remission 24 months after transplant. Both patients have developed chronic graft-versus-host disease and their Karnofsky performance status is 90%. AlloSCT may offer a useful approach in a subgroup of patients with mantle-cell lymphoma who have relapsed after autologous transplantation.

Abstract
BACKGROUND Autologous stem cell transplantation (ASCT) is increasingly performed on an outpatient basis. Preliminary results show a significant financial saving without modifying the therapeutic results. The aim of this study has been to evaluate the feasibility of this procedure in our the Hospital Clínic of Barcelona, Spain. PATIENTS AND METHODS All patients in whom an ASCT due to a hematological malignancy, having a good performance status, a caregiver 24 h per day, a lodging near to the hospital and an appropriate cultural and social environment, were offered an outpatient management starting the day after stem cell administration (day +1). RESULTS During the study period (April, 1997-June, 1998) 64 ASCT were performed. Fifteen patients (23%) were managed on an outpatient basis. The remaining patients were not included in the study due to patient preference (26%), medical reasons (22%), distant home (18%) and social problems (9%). Seven patients (47%) had to be readmitted in the hospital due to fever (n = 4), nausea (n = 2) or respiratory distress (n = 1). Patients receiving total body radiation (TBI) in the conditioning regimen did not have a higher readmission rate than those conditioned without TBI. The median hospital stay (since day +1) was 6 (range: 0-22) and 17 (13-117) days for outpatient and inpatients respectively (p = 0.0016). This reduction would imply a saving of 65% in hospitalization charges and of 12% in total charges. All patients having elected the outpatient management were very satisfied by having made that choice. CONCLUSION With an appropriate patient selection, outpatient ASCT is a feasible method that may improve the quality of life of the patients and can reduce the costs of the procedure.

Abstract
Gaucher's disease is an uncommon disorder which has been reported to be associated with an increased risk of lymphoproliferative disorders, including Non-Hodgkin's lymphoma (NHL). A new instance of such an association is described here. This was a 58 year-old-patient with adult type I Gaucher's disease who, one and a half year after the above diagnosis, presented with supraclavicular lymphadenopathy, massive splenomegaly, prominent retroperitoneal lymphadenopathy and increased serum LDH levels. This led to the diagnosis of large-cell NHL of B-cell type, successfully treated with chemotherapy. The previously published cases of Gaucher's disease associated with NHL as well as the possible mechanisms leading to this association are reviewed here.

Abstract
BACKGROUND Several studies have shown the potential advantages laparoscopic splenectomy (LS) over open surgery. The aim of this study has been to evaluate the advantages of LS over open surgery in the treatment of autoimmune thrombocytopenia. PATIENTS AND METHODS 54 consecutive patients splenectomized for the treatment of idiopathic thrombocytopenic purpura (ITP) or HIV-related thrombocytopenia were analyzed. Operative features (operative time, conversion to open surgery, accessory spleens), immediate (stay, analgesia and blood transfusion requirements) and late postoperative features (platelet count), as well as splenectomy-related complications in both surgical procedures were compared. RESULTS Between February 1990 and February 1997, 54 splenctomies were performed for the treatment of autoimmune thrombocytopenia (ITP, n = 47, and HIV-related thrombocytopenia, n = 7). Eighteen were performed through an open approach, and 36 by laparoscopy. Both groups were comparable with regard to age, sex, platelet count, disease duration and body mass index. LS was completed in 34 cases (conversion to open surgery: 5.5%). The incidence of accessory spleens was 11% in the LS group and 5.5% in the open surgery group. Postoperative morbidity (16% vs 28%) and blood requirements (25% vs 33%) were lower after LS, but the differences did not reach statistical significance. Analgesia requirements (7 [SD 3] vs 11 [6]; p < 0.01) and postoperative stay (3.8 [2.6] vs 7.4 [3] days; p < 0.01) were significantly shorter after LS. Following splenectomy, the platelet counts became normal in 72% of patients submitted to LS and 78% of patients in the open surgery group. After 20 and 63 months mean follow-up, one patient in each group developed late complications. CONCLUSION As compared to open surgery, LS offers a better immediate clinical outcome, with similar long-term results.

Abstract
Patients with diffuse large-cell lymphoma (DLCL) achieve a complete response (CR) in most cases, but at least one-third of them eventually relapse. Such an event occurs most frequently within 2 yr from CR achievement. The aim of the present study was to analyse the risk and pattern of relapse of patients with DLCL in CR. One hundred and three patients with DLCL (53 male/50 female; median age: 55 yr) in CR after doxorubicin-containing first-line treatments were included in the study. Main clinicobiological characteristics at diagnosis and at relapse were analysed. Uni- and multivariate studies were performed. Forty-one patients (40%) eventually relapsed, in 27 cases within 2 yr from CR and 14 thereafter. Histological subtype was the same at diagnosis and at relapse in all the early relapsing patients and in 8 of 10 late relapsing patients with available biopsy. The most important variables at diagnosis for predicting relapse were advanced stage (p<0.01) and bone marrow infiltration (p=0.05), with stage (I-II vs. III-IV) (p=0.009; relative risk=2.28) being the only predictive variable in the multivariate analysis. No differences were found according to the treatment given. The second CR rate obtained in the late relapsing patients after salvage therapies was higher that in early relapsing (50% vs. 37%). Median survival from relapse was 1.4 yr for patients early relapsing and it was not achieved for those with late relapses (p=0.09). Late relapse is a quite common event in DLCL lymphomas, with those patients achieving more frequently a second CR and having better survival than early relapsed patients.
