Abstract
BACKGROUND Follicular lymphoma (FL) and marginal zone lymphoma (MZL) are indolent non-Hodgkin lymphomas (iNHL). Median survival for iNHL is approximately 20 years. Because standard treatments are not curative, patients often receive multiple lines of therapy with associated toxicity-rationally designed, combination therapies with curative potential are needed. The immunomodulatory drug lenalidomide was evaluated in combination with rituximab for the frontline treatment of FL in the phase 3 RELEVANCE study. Ibrutinib, an oral Bruton tyrosine kinase inhibitor, is active in NHL and was evaluated in combination with lenalidomide, rituximab, and ibrutinib (IRR) in a phase 1 study. METHODS The authors conducted an open-label, phase 2 clinical trial of IRR for previously untreated FL and MZL. The primary end point was progression-free survival (PFS) at 24 months. RESULTS This study included 48 participants with previously untreated FL grade 1-3a (N = 38), or MZL (N = 10). Participants received 12, 28-day cycles of lenalidomide (15 mg, days 1-21 cycle 1; 20 mg, cycles 2-12), rituximab (375 mg/m2 weekly in cycle 1; day 1 cycles 2-12), and ibrutinib 560 mg daily. With a median follow-up of 65.3 months, the estimated PFS at 24 months was 78.8% (95% confidence interval [CI], 68.0%-91.4%) and 60-month PFS was 59.7% (95% CI, 46.6%-76.4%). One death occurred unrelated to disease progression. Grade 3-4 adverse events were observed in 64.6%, including 50% with grade 3-4 rash. CONCLUSIONS IRR is highly active as frontline therapy for FL and MZL. Compared to historical results with lenalidomide and rituximab, PFS is similar with higher grade 3-4 toxicity, particularly rash. The study was registered with ClinicalTrials.gov (NCT02532257).

Abstract
PURPOSE This pilot study of a diet and physical activity intervention (HEALTH4CLL) was conducted to reduce fatigue and improve physical function (PF) in patients with chronic lymphocytic leukemia (CLL). METHODS The HEALTH4CLL study used a randomized factorial design based on the multiphase optimization strategy (MOST). Patients received diet, exercise, and body weight management instructional materials plus a Fitbit and were randomized to undergo one of 16 combinations of 4 evidence-based mHealth intervention strategies over 16 weeks. Patients' fatigue, PF, health-related quality of life, behavior changes, and program satisfaction and retention were assessed. Paired t-tests were used to examine changes in outcomes from baseline to follow-up among patients. Factorial analysis of variance examined effective intervention components and their combinations regarding improvement in fatigue and PF scores. RESULTS Among 31 patients, we observed significant improvements in fatigue (+ 11.8; t = 4.08, p = 0.001) and PF (+ 2.6; t = 2.75, p = 0.01) scores. The combination of resistance and aerobic exercise with daily self-monitoring was associated with improved fatigue scores (β = 3.857, SE = 1.617, p = 0.027). Analysis of the individual components of the MOST design demonstrated greater improvement in the PF score with resistance plus aerobic exercise than with aerobic exercise alone (β = 2.257, SE = 1.071, p = 0.048). CONCLUSIONS Combined aerobic and resistance exercise and daily self-monitoring improved PF and reduced fatigue in patients with CLL. IMPLICATIONS FOR CANCER SURVIVORS This pilot study supported the feasibility of a low-touch mHealth intervention for survivors of CLL and provided preliminary evidence that exercising, particularly resistance exercise, can improve their symptoms and quality of life.

Abstract
We conducted a population-based study of patients >65 years, diagnosed 2008-2017, with peripheral T-cell lymphoma (PTCL) using SEER-Medicare. Associations between PTCL subtype, treatment regimen, comorbidity, and mortality were assessed using the Kaplan-Meier method and multivariable Cox regression. Amongst the 2,546 patients, the median age was 77 years (interquartile range, 71-83). 5-year overall survival (OS) ranged from 22.2% to 37.3% depending on PTCL subtype. The most common frontline regimen was cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP). 5-year OS rate was 47.0% for patients treated with etoposide + CHOP (N = 67; CHOEP), 33.7% for those treated with CHOP (N = 732), and 23.8% for patients treated with non-anthracycline-containing regimens (N = 105; p < 0.001). In patients without comorbidities, CHOEP remained independently associated with improved OS (HR 0.52, 95% CI,0.30-0.91). Median OS was 1.2 years from initiation of second-line therapy (N = 228) independent of treatment regimen. Frontline but not second-line treatment regimen is associated with OS in older patients with PTCL.

Abstract
Chimeric antigen receptor T-cell therapy (CART) has extended survival of patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL). However, limited durability of response and prevalent toxicities remain problematic. Identifying patients who are at high risk of disease progression, toxicity, and death would inform treatment decisions. Although the cumulative illness rating scale (CIRS) has been shown to correlate with survival in B-cell malignancies, no prognostic score has been independently validated in CART recipients. We retrospectively identified 577 patients with relapsed/refractory DLBCL indicated for CART at 9 academic centers to form a learning cohort (LC). Random survival forest modeling of overall survival (OS) and progression-free survival (PFS) was performed to determine the most influential CIRS organ systems and severity grades. The presence of a severe comorbidity (CIRS score ≥ 3) in the respiratory, upper gastrointestinal, hepatic, or renal system, herein termed "Severe4," had the greatest impact on post-CART survival. Controlling for other prognostic factors (number of prior therapies, Eastern Cooperative Oncology Group performance status, BCL6 translocation, and molecular subtype), Severe4 was strongly associated with shorter PFS and OS in the LC and in an independent single-center validation cohort (VC). Severe4 was also a significant predictor of grade ≥3 cytokine release syndrome in the LC, while maintaining this trend in the VC. Thus, our results indicate that adverse outcomes for patients with DLBCL meant to receive CART can be predicted using a simplified CIRS-derived comorbidity index.

Abstract
BACKGROUND Continuous ibrutinib administration is needed to maintain efficacy in patients with chronic lymphocytic leukemia (CLL) and, as such, long-term toxicity is a concern. The authors report the 5-year follow-up of patients with CLL who received treatment with ibrutinib with a focus on hypertension and cardiovascular toxicities. METHODS Patient characteristics were assessed, including blood pressure, cardiovascular disease, disease progression, and death. Univariate logistic regression analysis assessed the relation of patient characteristics and the development of new or worsened hypertension. The incidence of hypertensive outcomes was evaluated using competing risk. Survival was estimated using the Kaplan-Meier method. RESULTS Three hundred patients with CLL who were treated with ibrutinib on clinical trials were included. The median patient age at study enrollment was 65 years (range, 29-83 years). Seventy percent of patients were men, and 88% were Caucasian. Sixty-nine percent of patients had hypertension at baseline, and 47% were on antihypertensive medication. Eighty-eight percent had relapsed or refractory CLL. New-onset and worsening hypertension were common, occurring in 68.5% and 38% of patients, respectively. Systolic blood pressure ≥160 mm Hg or diastolic blood pressure ≥100 mm Hg was observed in 16.9% of patients. Hypertension was reversible after ibrutinib discontinuation. Older age, male sex, tobacco use, and chronic kidney disease were associated with ibrutinib-related hypertension. Baseline hypertension was not associated with major adverse cardiovascular events in ibrutinib-treated patients nor with event-free or overall survival. CONCLUSIONS Hypertension is a common toxicity in patients with CLL who receive ibrutinib but is manageable in most patients. Other than chronic kidney disease, baseline cardiovascular disease did not affect ibrutinib-related hypertension nor was hypertension associated with major adverse cardiovascular events or survival. PLAIN LANGUAGE SUMMARY Ibrutinib is an effective treatment for patients with chronic lymphocytic leukemia. Ibrutinib is a well tolerated therapy, however hypertension can develop or worsen in patients receiving ibrutinib and other cardiovascular events are significant challenges to the use of this drug. This may be particularly true in patients with heart disease. Short-term side effects may worsen heart disease, but the long-term impact is unknown. The long-term results of ibrutinib on heart disease and hypertension are described.

Abstract
For patients with non-Hodgkin lymphoma (NHL), formal comorbidity assessment is recommended but is rarely conducted in routine practice. A simple, validated measure of comorbidities that standardizes their assessment could improve adherence to guidelines. We previously constructed the 3-factor risk estimate scale (TRES) among patients with chronic lymphocytic leukemia (CLL). Here, we investigated TRES in multiple NHL subtypes. In the surveillance, epidemiology, and end results-Medicare database, patients with NHL diagnosed from 2008 to 2017 were included. Upper gastrointestinal, endocrine, and vascular comorbidities were identified using ICD-9/ICD-10 codes to assign TRES scores. Patient characteristic distributions were compared using χ2 or t test. Association of mortality and TRES score was assessed using Kaplan-Meier and multivariable Cox regression model for competing risk. A total of 40 486 patients were included in the study. Median age was 77 years (interquartile range [IQR], 71-83 years). The most frequent NHL subtypes were CLL (28.2%), diffuse large B-cell (27.6%), and follicular lymphoma (12.6%). Median follow-up was 33 months (IQR, 13-60 months). TRES was low, intermediate, and high in 40.8%, 37.0%, and 22.2% of patients, corresponding to median overall survival (OS) of 8.2, 5.3, and 2.9 years (P < .001), respectively. TRES was associated with OS in all NHL subtypes. In multivariable models, TRES was associated with inferior OS and NHL-specific survival. TRES is clinically translatable and associated with OS and lymphoma-specific survival in older adults with NHL.

Abstract
The prognostic relevance of diagnosis to treatment interval (DTI) in patients with newly diagnosed mantle cell lymphoma (MCL) is unknown. Hence, we sought to evaluate the impact of DTI on outcomes in MCL using 3 large datasets (1) the University of Iowa/Mayo Clinic Specialized Program of Research Excellence Molecular Epidemiology Resource, (2) patients enrolled in the ALL Age Asthma Cohort/CALGB 50403, and (3) a multisitecohort of patients with MCL. Patients were a priori divided into 2 groups, 0 to 14 days (short DTI) and 15 to 60 days (long DTI). The patients in whom observation was deemed appropriate were excluded. One thousand ninety-seven patients newly diagnosed with MCL and available DTI were included in the study. The majority (73%) had long DTI (n=797). Patients with short DTI had worse eastern cooperative oncology group performance status (ECOG PS ≥2), higher lactate dehydrogenase, bone marrow involvement, more frequent B symptoms, higher MCL International Prognostic Index (MIPI ≥6.2), and were less likely to receive intensive induction therapy than long DTI group. The median progression-free survival (2.5 years vs 4.8 years, p<0.0001) and overall survival (7.8 years vs. 11.8 years, p<0.0001) were significantly inferior in the short DTI group than the long DTI cohort and remained significant for progression-free survival and overall survival in multivariable analysis. We show that the DTI is an important prognostic factor in patients newly diagnosed with MCL and is strongly associated with adverse clinical factors and poor outcomes. DTI should be reported in all the patients newly diagnosed with MCL who are enrolling in clinical trials and steps must be taken to ensure selection bias is avoided.

Abstract
OBJECTIVE Examine physical function and T-cell phenotype in patients with chronic lymphocytic leukemia (CLL) before and after a physical activity (PA) intervention. METHODS Physical function measures and blood samples were collected from CLL patients (Rai stage 0-4, 50% receiving targeted therapy, N = 24) enrolled in a 16-week intervention of at-home aerobic and/or resistance exercise. Flow cytometry characterized T-cells in cryopreserved peripheral blood cells. Wilcoxon signed-rank test compared physical function and T-cell phenotype at baseline and 16-weeks; Kendall's Tau assessed associations between variables. RESULTS Godin leisure-time PA score increased from baseline to 16-weeks (mean difference: 14.61, p < .01) and fatigue decreased (mean difference: 6.71, p < .001). At baseline, lower fatigue correlated with a lower proportion of CD8+ T-cells (τ = 0.32, p = .03) and cardiorespiratory fitness (CRF) inversely correlated with the percentage of PD-1+CD8+ T-cells (τ -0.31, p = .03). At 16-weeks, CRF inversely correlated with the proportion of PD-1+CD4+ T-cells (τ -0.34, p = .02). Reduced fatigue at 16-weeks correlated with an increased CD4:CD8 ratio (τ = 0.36, p = .02) and lower percentage of HLA-DR+PD-1+CD4+ T-cells (τ = -0.37, p = .01). CONCLUSIONS This intervention increased leisure-time PA and decreased fatigue in CLL patients. These changes correlated with an increased CD4:CD8 T-cell ratio and reduced proportion of T-cells subsets previously associated with poor outcomes in CLL patients. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT02194387.

Abstract
Follicular lymphoma, the most common indolent lymphoma, though highly responsive to therapy is coupled with multiple relapses for the majority of patients. Advances in biologic understanding of molecular events in lymphoma cells and the tumor microenvironment, along with novel cellular and targeted therapies, suggest this may soon change. Here we first review the development of the molecular concepts and classification of follicular lymphoma, along with therapeutic development of treatments based on chemotherapy plus monoclonal antibodies targeting CD20. We then focus on developments over the last decade in further defining follicular lymphoma pathophysiology, leading to targeted therapeutics, as well as novel immunotherapeutic strategies effective against B cell lymphomas including follicular, particularly patients with advanced stage disease. Additional alterations beyond the hallmark t(14;18) translocation are necessary for development of follicular lymphoma. Epigenetic mutations are almost universally identified in follicular lymphoma, most commonly involving histone-lysine N-methyltransferase 2D (KMT2D, the histone acetyltransferases, cAMP response element-binding protein binding protein (CREBBP) and E1A binding protein P300 (EP300) and the histone methyltransferase enhancer of zeste homologue 2 (EZH2). Mutations are also commonly identified in other proliferation/survival pathways such as B-cell receptor, RAS, mTOR and JAK-STAT pathways, as well as immune escape mutations. The host immune response plays a key role as well, based on studies correlating various immune cell subsets and gene expression signatures with outcomes. Over the last decade, many therapeutic options beyond the commonly used bendamustine-rituximab induction regimen have become available or are being investigated. We focus on these newer agents in the relapsed setting. New antibody-based agents include the naked CD19 directed antibody tafasitamab, the CD79b directed antibody drug conjugate (ADC) polatuzumab vedotin and the CD47 directed antibody magrolimab that targets macrophages rather than FL cells directly. Immune modulation by lenalidomide has moved to earlier lines of therapy and in combinations. Several small molecule inhibitors of proliferation signal pathways involving PI3kinase and BTK have activity against FL. Apoptotic pathway modulators also have activity. With increasing recognition of the high rate of epigenetic mutations in FL, HDAC inhibition has a role. More importantly, the EZH2 inhibitor tazemetostat is FDA approved for FL after 2 prior lines of therapy. The most exciting data currently involve immune attack against follicular lymphoma by chimeric antigen receptor T-cells (CART) or bispecific antibody constructs. Given these multiple potentially non-crossreactive mechanisms, studies of rationally designed combination strategies hold the promise of improving outcomes and possibly cure of follicular lymphoma.

Abstract
Chronic lymphocytic leukemia (CLL) is a common, indolent disease that typically presents with a proliferation of mature, immunologically dysfunctional CD5+ B-cells which preferentially occupy the bone marrow, peripheral blood and lymphoid organs. Immune dysfunction leads to an increase in autoimmune diseases which occur in approximately 10% of patients with CLL. Autoimmune cytopenias are the most common, but other organs may be affected as well. The treatment of these conditions typically depends on the extent of CLL and severity of symptoms, but generally consists of CLL-directed therapies, immunosuppression or both. CLL may also infiltrate extranodal sites in the body. Symptomatic extranodal CLL or extranodal disease which threatens normal organ function is an indication for initiation of CLL-directed therapy. The following review summarizes autoimmune and extranodal complications that can occur in patients with CLL and our suggested approach to their treatment.

Abstract
Diffuse large B-cell lymphoma (DLBCL) is the most common type of aggressive non-Hodgkin lymphoma. Combination chemotherapy with immunotherapy can be curative, however, nearly one-third of patients will have a disease that is refractory or will relapse (R/R) after standard first-line therapy. In second-line, the standard treatment strategy for fit patients has been high dose chemotherapy followed by autologous stem cell transplant for a quarter-century, however more than half of patients have chemotherapy-refractory disease with this approach. The patients not cured with current chemotherapy-based approaches may benefit from immunotherapy. Several classes of immunotherapy have been developed including antibody-drug conjugates, bispecific T-cell engaging antibodies, immune checkpoint inhibitors and chimeric antigen receptor T-cells. In the following review, we discuss the currently available immunotherapeutic options for patients with R/R DLBCL.

Abstract
High-grade B-cell lymphoma with MYC and BCL2 and/or BCL6 rearrangements or both, commonly called double-hit lymphoma (DHL), is an aggressive B-cell lymphoma that is molecularly distinct from diffuse large B-cell lymphoma (DLBCL) and is associated with poor outcomes. Recent advances in the molecular classification of DLBCL have identified distinct subsets, including genetic signatures which correlate with DHL and survival. DHL with concomitant TP53 mutation appears to be associated with a very poor prognosis. Standard chemo-immunotherapy is not an effective treatment for these patients and personalized, innovative strategies are needed. In this review, we summarize recent advances in the subclassification of DLBCL, with a focus on DHL. We also incorporate early, promising clinical trial data using CAR T and targeted therapies. Rationally designed clinical trials for DLBCL are needed to advance the care of patients with DHL and other adverse risk DLBCL subgroups.

Abstract
Clinical outcomes and predictors of survival in patients with newly diagnosed mantle cell lymphoma (MCL) treated in the rituximab era (2000-2015) at 12 US academic centers were assessed to identify determinants of survival across age groups. Objectives were to characterize and compare practice patterns, outcomes and prognostic factors for survival in younger patients (age < 65) and older patients (age ≥ 65 years). Among 1162 patients included, 697 were younger and 465 were older. In younger patients, 2-year progression free survival (PFS) and overall survival (OS) rates were 79% and 92% respectively; blastoid histology, ECOG ≥ 2, and lack of maintenance rituximab (MR) remained statistically relevant to poor OS on univariate analysis (UVA) and multivariate analysis (MVA). In older patients, 2-year PFS and OS rates were 67% and 86% respectively; lack of maintenance rituximab remained significantly associated with inferior PFS and OS on UVA and MVA (p < 0.001). Two-year PFS rates were 79%, and 67% and 2-year OS rates were 92% and 86% for ages < 65 and ≥ 65 respectively (p < 0.001). First-line high-dose cytarabine exposure and/or MR lessened the negative impact of age on survival. Taken collectively, survival outcomes for older patients remain inferior to those of younger patients in the rituximab era. However, maintenance rituximab and potentially high-dose cytarabine-based induction can mitigate the negative impact of age on survival.

Abstract
PURPOSE Comorbid medical conditions define a subset of patients with chronic lymphocytic leukemia (CLL) with poor outcomes. However, which comorbidities are most predictive remains understudied. EXPERIMENTAL DESIGN We conducted a retrospective analysis from 10 academic centers to ascertain the relative importance of comorbidities assessed by the cumulative illness rating scale (CIRS). The influence of specific comorbidities on event-free survival (EFS) was assessed in this derivation dataset using random survival forests to construct a CLL-specific comorbidity index (CLL-CI). Cox models were then fit to this dataset and to a single-center, independent validation dataset. RESULTS The derivation and validation sets comprised 570 patients (59% receiving Bruton tyrosine kinase inhibitor, BTKi) and 167 patients (50% receiving BTKi), respectively. Of the 14 CIRS organ systems, three had a strong and stable influence on EFS: any vascular, moderate/severe endocrine, moderate/severe upper gastrointestinal comorbidity. These were combined to create the CLL-CI score, which was categorized into 3 risk groups. In the derivation dataset, the median EFS values were 58, 33, and 20 months in the low, intermediate, and high-risk groups, correspondingly. Two-year overall survival (OS) rates were 96%, 91%, and 82%. In the validation dataset, median EFS values were 81, 40, and 23 months (two-year OS rates 97%/92%/88%), correspondingly. Adjusting for prognostic factors, CLL-CI was significantly associated with EFS in patients treated with either chemo-immunotherapy or with BTKi in each of our 2 datasets. CONCLUSIONS The CLL-CI is a simplified, CLL-specific comorbidity index that can be easily applied in clinical practice and correlates with survival in CLL.

Abstract
Central nervous system (CNS) involvement in Burkitt lymphoma poses a major therapeutic challenge, and the relative ability of contemporary regimens to treat CNS involvement remains uncertain. We describe the prognostic significance of CNS involvement and the incidence of CNS recurrence/progression after contemporary immunochemotherapy using real-world clinicopathological data from adults with Burkitt lymphoma diagnosed between 2009 and 2018 in 30 institutions in the USA. We examined associations between baseline CNS involvement, patients’ characteristics, complete response rates, and survival. We also examined risk factors for CNS recurrence. Of 641 patients (aged 18 to 88 years), 120 (19%) had CNS involvement. CNS involvement was independently associated with human immunodeficiency virus infection, poor performance status, involvement of ≥2 extranodal sites, and bone marrow involvement. Selection of the first-line treatment regimen was unaffected by CNS involvement (P=0.93). Patients with CNS disease had significantly lower rates of complete response (59% vs. 77% for patients with and without CNS involvement, respectively; P<0.001), worse 3-year progression-free survival (adjusted hazard ratio [aHR]=1.53, 95% confidence interval [95% CI]: 1.14-2.06; P=0.004) and overall survival (aHR=1.62, 95% CI: 1.18-2.22; P=0.003). The 3-year cumulative incidence of CNS recurrence was 6% (95% CI: 4-8%) and was significantly lower among patients receiving other regimens (CODOX-M/IVAC, 4%, or hyperCVAD/MA, 3%) compared with DA-EPOCH-R (13%; adjusted sub-distribution HR=4.38, 95% CI:, 2.16-8.87; P<0.001). Baseline CNS involvement in Burkitt lymphoma is relatively common and portends inferior prognosis independently of the first-line treatment regimen selected. In real-world practice, regimens including intravenous systemic agents with pronounced CNS penetrance were associated with a lower risk of CNS recurrence. This finding may be influenced by observed suboptimal adherence to the strict CNS staging and intrathecal therapy procedures incorporated in the DA-EPOCH-R regimen.

Abstract
INTRODUCTION While most patients with mantle cell lymphoma (MCL) receive therapy shortly after diagnosis, a subset of patients with indolent-behaving disease can safely defer treatment. In this subgroup, we evaluated the importance of treatment intensity in patients with MCL who defer initial therapy. METHODS Out of 1134 patients with MCL from 12 academic centers, we analyzed 219 patients who initiated therapy at least 90 days after diagnosis. Patients who received induction with high-dose cytarabine and/or autologous stem cell transplantation (ASCT) in first remission were considered to have received intensive therapy (n = 88) while all other approaches were non-intensive (n = 131). RESULTS There was no difference in progression-free (PFS; P = .224) or overall survival (OS; P = .167) in deferred patients who received non-intensive vs. intensive therapy. Additionally, univariate and multivariate Cox proportional hazards models were performed for PFS and OS. Treatment at an academic center (HR 0.43, P = .015) was associated with improved OS in both univariate and multivariate models, while intensity of treatment was not associated with improved OS in either model. CONCLUSIONS These results indicate that intensified initial treatment is not associated with improved survival after deferring initial therapy, although prospective studies are needed to determine which of these patients with MCL may benefit from intensive therapy.

Abstract
Ibrutinib, the first in class of the oral covalent Bruton tyrosine kinase (BTK) inhibitors, has profoundly changed the treatment landscape of chronic lymphocytic leukemia (CLL). The phase III RESONATE and RESONATE-2 trials first demonstrated the superiority of ibrutinib over ofatumumab in the relapsed/refractory setting and over chlorambucil in older patients with de novo disease. The phase III ECOG–ACRIN trial extended these results to young, fit patients, demonstrating a significant survival advantage to ibrutinib plus rituximab over fludarabine, cyclophosphamide, and rituximab. Similarly, the Alliance trial demonstrated the superiority of ibrutinib over bendamustine with rituximab as frontline in elderly patients. Challenges with ibrutinib include toxicity, development of resistance, and need for indefinite therapy. The second generation BTK inhibitor acalabrutinib may cause less off-target toxicity. The ELEVATE TN trial demonstrated the superiority of acalabrutinib with or without obinutuzumab over chlorambucil and obinutuzumab as frontline therapy for elderly or comorbid patients. Promising early results from the phase II CAPTIVATE and CLARITY trials, which combined ibrutinib with venetoclax, suggest a future role for minimal residual disease (MRD) testing to determine treatment duration. The ongoing phase III GAIA/CLL13, ECOG EA9161, Alliance A041702, CLL17, and [ClinicalTrials.gov identifier: NCT03836261] trials will assess various combinations of ibrutinib/acalabrutinib, venetoclax, and anti-CD20 antibodies. These trials will answer key questions in the treatment of CLL: should novel agents in CLL be used in combination or sequentially? What is the best frontline agent? Can treatment be safely stopped with BTK inhibitors? Can undetectable MRD be used to determine treatment duration? In this review, we will discuss these and other aspects of the evolving role of BTK inhibition in CLL.

Abstract
Comorbidities influence survival in patients with chronic lymphocytic leukaemia (CLL) treated with chemo-immunotherapy or ibrutinib. While idelalisib has been studied in patients with comorbidities, their impact has not been investigated. We analysed 481 patients treated with idelalisib on two randomised trials (NCT01659021 and NCT01539512). Comorbidities were assessed using the Cumulative Illness Risk Scale (CIRS). Patients received idelalisib + anti-CD20 (rituximab or ofatumumab; n = 284) or anti-CD20 alone (n = 197). The median age was 69 years. We found that comorbidities did not significantly affect outcomes of idelalisib therapy. The objective response rate (ORR) was 79·3% versus 85·8%, the median progression-free survival (PFS) was 16·3 versus 19·1 months, and the median overall survival (OS) was 39·8 versus 49·8 months in patients treated with idelalisib who had a CIRS score of >6 versus ≤6, correspondingly. Treatment with idelalisib + anti-CD20 was associated with superior PFS and ORR when compared to anti-CD20 monotherapy in patients who had high comorbidities (CIRS score of >6) or at least one severe comorbidity (median PFS 16·3 vs. 6·9 months and 16·6 vs. 6·5 months; odds ratio 20·1 and 33·2; P < 0·0001). Thus, comorbidities do not portend inferior outcomes in patients with CLL treated with idelalisib in combination with anti-CD20 therapy.

Abstract
BACKGROUND Risk stratification of newly diagnosed patients with mantle cell lymphoma (MCL) primarily is based on the MCL International Prognostic Index (MIPI) and Ki-67 proliferative index. Single-center studies have reported inferior outcomes in patients with a complex karyotype (CK), but this remains an area of controversy. METHODS The authors retrospectively reviewed 483 patients from 5 academic centers in the United States and described the effect of a CK on survival outcomes in individuals with MCL. RESULTS A CK was found to be associated with inferior overall survival (OS) (4.5 vs 11.6 years; P<.01) and progression-free survival (PFS) (1.9 vs 4.4 years; P<.01). In patients who underwent high-intensity induction followed by autologous stem cell transplantation (ASCT) in first remission, a CK was associated with poor OS (5.1 vs 11.6 years; P = .04) and PFS (3.6 vs 7.8 years; P<.01). Among patients with a CK, high-intensity induction had no effect on OS (4.5 vs 3.8 years; P = .77) nor PFS (2.3 vs 1.5 years; P = .46). Similarly, ASCT in first remission did not improve PFS (3.5 vs 1.2 years; P = .12) nor OS (5.1 vs 4.0 years; P = .27). On multivariable analyses with Ki-67 and MIPI, only CK was found to be predictive of OS (hazard ratio [HR], 1.98; 95% confidence interval [95% CI], 1.12-3.49 [P = .02]), whereas both CK (HR, 1.91; 95% CI, 1.17-3.12 [P = .01]) and Ki-67 >30% (HR, 1.86; 95% CI, 1.06-3.28 [P = .03]) were associated with inferior PFS. Multivariable analysis did not identify any specific cytogenetic abnormalities associated with inferior survival. CONCLUSIONS CK appears to be independently associated with inferior outcomes in patients with MCL regardless of the intensity of induction therapy and receipt of ASCT. Cytogenetics should be incorporated into the workup of a new diagnosis of MCL and novel therapeutic approaches should be investigated for patients with CK.

Abstract
INTRODUCTION The majority of patients with non-Hodgkin lymphoma (NHL) and chronic lymphocytic leukemia (CLL) present with comorbidities. Many of them are poor candidates for intensive chemo-immunotherapy regimens, such as FCR (fludarabine, cyclophosphamide, rituximab). Still, most clinical trials aim to enroll 'fit' patients, who poorly represent the community oncology population. Areas covered: In the past decade, bendamustine hydrochloride, a cytotoxic agent with structural similarities to both alkylating agents and purine analogs, has received widespread use in therapy of NHL and CLL, and has demonstrated a relatively favorable toxicity profile. However, bendamustine has not been well studied in patients with hematologic malignancies who have comorbidities. Here we review the clinical data on use of bendamustine in older and unfit patients with NHL and CLL, and analyze whether there is an optimal dose of bendamustine in patients who have significant comorbidities, including renal dysfunction. Expert commentary: Reduced intensity regimens of bendamustine are effective in CLL patients with comorbidities and renal dysfunction. Even with the introduction of targeted therapies, bendamustine will likely continue to be an important therapeutic option in patients with comorbidities because of its tolerability, efficacy and cost.

Abstract
PURPOSE Identify AML patients most likely to respond to CPX-351, a nano-scale liposome formulation containing cytarabine and daunorubicin co-encapsulated at a 5:1 molar ratio. METHODS We examined the ex vivo cytotoxic activity of CPX-351 against leukemic cells isolated from 53 AML patients and an additional 127 samples including acute lymphoblastic leukemia, myelodysplastic syndrome/myeloproliferative neoplasms, or chronic lymphocytic leukemia/lymphoma. We assessed activity with respect to common molecular lesions and used flow cytometry to assess CPX-351 cellular uptake. RESULTS AML specimen sensitivity to CPX-351 was similar across conventional risk groups. FLT3-ITD cases were five-fold more sensitive to CPX-351. CPX-351 was active across other indications with nearly all cases exhibiting IC50 values markedly lower than reported 72-h plasma drug concentration in patients receiving CPX-351. The range and distribution of CPX-351 IC50 values were comparable for AML, CLL, and ALL, whereas MDS/MPN cases were less sensitive. CPX-351 uptake analysis revealed a correlation between uptake of CPX-351 and cytotoxic potency. CONCLUSIONS Our findings are consistent with clinical data, in which CPX-351 activity is retained in high-risk AML patients. Ex vivo analysis of cytotoxic potency may provide a means to identify specific AML subsets, such as FLT3-ITD, that benefit most from CPX-351 and warrant additional clinical evaluation.

Abstract
OBJECTIVES The purpose of this study was to describe the clinical characteristics and outcomes in cardiac non-Hodgkin's lymphoma (NHL). METHODS A retrospective analysis of 94 cases of NHL with biopsy-proven cardiac involvement in PubMed between 1990 and 2015. RESULTS Among cases with cardiac involvement, diffuse large B-cell lymphoma was the most common histologic subtype (58%), followed by T-cell lymphoma (16%), Burkitt's lymphoma (9%), and small lymphocytic lymphoma (6%). Symptomatic heart failure was the most common clinical presentation (34%), and 20% of patients had no cardiac symptoms. Median survival was 3 months (range, 0-72) among all patients. Patients who presented with heart failure had inferior outcomes. Patients with primary, vs. secondary, cardiac involvement had a trend toward superior outcomes. Importantly, chemotherapy treatment was associated with a prolongation in median survival (18 vs. 1 month, HR 0.16, 95% CI, 0.47-0.54, P = 0.0003), and patients diagnosed in the chemo-immunotherapy era demonstrated a trend toward better outcomes. Median survival was not reached among patients with B-cell malignancies who were alive for 1 month after the diagnosis. CONCLUSION Pathologic lymphomatous involvement of cardiac tissue should be considered in the evaluation of patients with NHL. Durable remissions can be achieved in B-cell NHL with cardiac involvement, and thus, therapy should be considered in such cases.

Abstract
INTRODUCTION Enzalutamide (MDV3100) is a second-generation androgen receptor antagonist that improves survival in metastatic, castration-resistant prostate cancer (mCRPC). Alternatives include chemotherapy, radiation, immunotherapy and abiraterone. AREAS COVERED The Phase I/II study showed early evidence of efficacy and determined that fatigue is the dose-limiting toxicity. Two randomized, placebo-controlled trials have demonstrated superiority of enzalutamide 160 mg by mouth daily over placebo in terms of overall survival, radiographic progression-free survival as well as a broad range of secondary and exploratory end points in men who had received previous chemotherapy (AFFIRM) and in those who were chemotherapy naive (PREVAIL). Common side effects include fatigue, arthralgias and constipation. A post hoc analysis from AFFIRM found that enzalutamide is safe and effective in men aged ≥ 75 years. The Phase I/II studies as well as AFFIRM and PREVAIL are described in this review. EXPERT OPINION Enzalutamide extends overall and progression-free survival and is associated with robust response rates and quality of life benefits in men with mCRPC. Enzalutamide has not been proven to be effective in biochemically relapsed disease or in castration-sensitive prostate cancer. It should not be used in men at high risk for seizure, and patients should be counseled about the increased risk of falls.

Abstract
The involvement of glycoprotein (GP) IV (CD36) in arachidonic acid uptake by human platelets was investigated using an anti-CD36 monoclonal antibody (MAB). The binding of [(14)C]arachidonic acid to MAB-treated platelets was significantly reduced compared with untreated platelets. The MAB also inhibited arachidonic acid-induced platelet aggregation and thromboxane A(2) synthesis in a dose-dependent manner. Pre-incubation of gel-filtered platelets with the MAB (10mg/I) inhibited arachidonic acid-induced platelet aggregation by 50% and collagen-induced platelet aggregation by 7-8% and the lag time was increased by 200%. Although the mechanism of platelet aggregation is not fully understood yet, the inhibition of arachidonic acid-induced platelet aggregation by the MAB could be the result of a reduced uptake of exogeneously added arachidonic acid by the MAB-treated platelets. Our data clearly indicate that arachidonic acid uptake by platelets is mediated, at least in part, by CD36.

Abstract
A reflection-mode, confocal, tip-enhanced Raman spectroscopy system for nanoscale chemical imaging of surfaces is presented. The instrument is based on a beam-bounce atomic force microscope with a side-on Raman microscope with true confocal light illumination and collection. Localized vibrational (Raman) spectroscopy is demonstrated at length scales down to 20 nm on opaque samples. The design and validation of the instrument are discussed with quantitative emphasis on confocal microscope operation, plasmonic properties of the tip, point spectroscopy, and Raman imaging of SiGe nanowires.

Abstract
The effect of pure flavonoids and Gingko biloba extract (GBE) on human platelet aggregation was investigated. Most of the flavonoids and vitamin E did not affect platelet aggregation in platelet-rich plasma (PRP); however some of these flavonoids inhibited platelet aggregation in gel-filtered platelets (GFP). GBE inhibited both ADP- and collagen-induced platelet aggregation in PRP, GFP and in whole blood in a dose-dependent manner. GBE at very low concentrations inhibited whole blood aggregation induced by ADP compared with those used for PRP or GFP. Flavonoids and GBE decreased the production of TxA(2) induced by collagen and ADP in PRP. However, no correlation was observed between the inhibition of platelet aggregation and the decrease of TxA(2) synthesis. GBE and flavonoids did not affect platelet membrane fluidity. However, the incubation of PRP with GBE increased cAMP levels in platelets, which is known to inhibit platelet activation by lowering intracellular Ca2+ levels. GBE is a mixture of many compounds, including flavonoids and gingkoglides, which affect metabolism of cAMP, TxA(2) and Ca2+ in platelets. It is effective in the inhibition of platelet aggregation, both in PRP and whole blood, and thus may be potentially used as an effective oral anti-platelet therapeutic agent.

Abstract
We report measurements of the de Haas-van Alphen effect in CeIn(3) in magnetic fields extending to approximately 90 T, well above the Néel critical field of mu(0)H(c) approximately 61 T. The unreconstructed Fermi surface a sheet is observed in the high magnetic field polarized paramagnetic limit, but with its effective mass and Fermi surface volume strongly reduced in size compared to that observed in the low magnetic field paramagnetic regime under pressure. The spheroidal topology of this sheet provides an ideal realization of the transformation from a "large Fermi surface" accommodating f electrons to a "small Fermi surface" when the f-electron moments become polarized.

Abstract
A high-flux beam of mass-filtered F+ at low energy (100-1300 eV) was scattered off Al and Si surfaces to study core-level excitations of F0 and F+. Elastic scattering behavior for F+ was observed at energies <300 (500) eV off Al (Si) for a 90 degrees lab angle. However, above this energy threshold, orbital mixing in the hard collision step results in electronic excitation of F via molecular orbital promotion along the 4f sigma (F-2p), significantly reducing the observed ion exit energy. In addition, despite the electronegativity of F, scattering at energies >450 (700) eV off Al (Si) produces F2+-behavior which is remarkably similar to Ne+ off the same surfaces. Inelasticities measured for single collision events agree well with the energy deficits required to form (doubly excited) F** and F+** states from F0 and F+, respectively; these excited species most likely decay to inelastic F+ and F2+ via autoionization.

Abstract
Among all fruits tested in vitro for their anti-platelet property, tomato had the highest activity followed by grapefruit, melon, and strawberry, whereas pear and apple had little or no activity. Tomato extract (20-50 microl of 100% juice) inhibited both ADP- and collagen-induced aggregation by up to 70% but could not inhibit arachidonic acid-induced platelet aggregation and concomitant thromboxane synthesis under similar experimental conditions. The anti-platelet components (MW <1000 Da) in tomatoes are water soluble, heat stable and are concentrated in the yellow fluid around the seeds. The active fractions were separated using gel filtration and HPLC. The aqueous fraction (110 000 xg supernatant) of tomatoes containing anti-platelet activity was subjected to gel filtration column chromatography (Biogel P2 column). The activity was fractionated into two peaks, peak-3 and peak-4 (major peak). Subsequently, peak-4 was further purified by HPLC using a reversed-phase column. NMR and mass spectroscopy studies indicated that peak F2 (obtained from peak 4) contained adenosine and cytidine. Deamination of peak F2 with adenosine deaminase almost completely abolished its anti-platelet activity, confirming the presence of adenosine in this fraction. In comparison, deamination of peak-4 resulted in only partial loss of inhibitory activity while the activity of peak-3 remained unaffected. These results indicate that tomatoes contain anti-platelet compounds in addition to adenosine. Unlike aspirin, the tomato-derived compounds inhibit thrombin-induced platelet aggregation. All these data indicate that tomato contains very potent anti-platelet components, and consuming tomatoes might be beneficial both as a preventive and therapeutic regime for cardiovascular disease.

Abstract
This systematic review and meta-analysis were undertaken to determine whether reduction mammaplasty improves measurable outcomes in women with breast hypertrophy. A systematic review of the literature in 5 languages from 1985 until March 1999 was performed, and data were compared for meta-analysis. Eligible studies were both experimental and observational and involved women with preoperative physical and/or psychosocial signs and symptoms who underwent reduction mammaplasty for breast hypertrophy. Outcomes assessed were postoperative physical signs and symptoms such as shoulder pain, shoulder (bra strap) grooving, and quality-of-life domains, such as physical and psychological functioning, and were expressed primarily as risk differences (RDs). Twenty-nine studies of 4173 patients met all eligibility criteria. Reduction mammaplasty was associated with a statistically significant improvement in physical signs and symptoms involving shoulder pain (RD, 0.71 [95% confidence interval (CI), 0.62-0.80]); shoulder grooving (RD, 0.69 [95% CI, 0.60-0.78]); upper/lower back pain (RD, 0.59 [95% CI, 0.48-0.70]); neck pain (RD, 0.50 [95% CI, 0.37-0.64]); intertrigo (RD, 0.44 [95% CI, 0.34-0.54]); breast pain (RD, 0.36 [95% CI, 0.17-0.55]); headache (RD, 0.28 [95% CI, 0.11-0.46]); and pain/numbness in the hands (RD, 0.11 [95% CI, 0.04-0.18]). The quality-of-life parameter of physical functioning was also statistically significant (RD, 0.58 [95% CI, 0.44-0.71]), while psychological functioning was not significant (RD, 0.46 [95% CI, 0.00-1.00]). The evidence suggests that women undergoing reduction mammaplasty for breast hypertrophy have significant postoperative improvement in preoperative signs and symptoms, quality of life, or both.

Abstract
We investigated the fatty acid distribution in guinea pig alveolar apical membranes at different developmental stages. Fatty acid composition of the purified membranes isolated from guinea pig fetuses (at 65 day, term=68 day), neonates (day 1) and adult males was determined. The levels of arachidonic acid (AA) and docosahexaenoic acid (DHA) were higher in the adult guinea pig alveolar apical membrane phosphatidylethanolamine (PE) fraction (9. 3+/-2.2 and 2.9+/-1.0%, respectively) while in other phospholipids (PL) fractions their levels were low or absent (P<0.01). Furthermore, levels of AA and DHA in the PE fraction of apical membrane increased significantly from fetal (6.6+/-3.0 and 0.8+/-0.4%, respectively) to neonatal life (10.3+/-1.5 and 3.0+/-0.8%, respectively). Increase in the level of DHA (almost four-fold) was much more pronounced than that of AA (P<0.05). As for guinea pig alveolar membranes, EPA and AA were mostly present in the PE fraction in pulmonary adenocarcinoma derived cells (A549 cells), a parallel model of type II pneumocytes, with the levels of AA around three-fold greater than that of EPA, Binding of radiolabelled fatty acids to A549 cells showed no significant differences between the maximum uptake achieved for different fatty acids (AA, 1.7+/-0.2, EPA, 2.3+/-0.3, LA, 1.7+/-0.2, OA, 2.0+/-0.2nmol/mg protein, P>0.5). Once the fatty acids were taken up by these cells AA was mostly identifiable in the monoacylglycerol (MAG) fraction, whereas EPA was equally distributed between the MAG and PL fractions. Oleic acid was mainly present in the triglyceride (TAG) fraction whereas LA was evenly distributed between the TAG, MAG, and PL fractions. Our data demonstrate a preferential distribution of AA and DHA in PE fractions of alveolar apical membranes during development.

Abstract
OBJECTIVE To replicate and to critique a recently published meta-analysis[1] of the incidence of nonpreventable serious and fatal adverse drug reactions (ADRs) in hospitalized patients, to better understand its results and conclusions. METHODS The published methods described in the meta-analysis of Lazarou and colleagues were followed.[1] This meta-analysis reviewed 30 original publications describing 39 prospective studies. In each study, the numbers of patients with nonpreventable ADRs, probably or definitely related to drugs, were sought to allow calculation of the incidence of "all-severities," serious and fatal, ADRs. In the original meta-analysis, these ADR incidences were then pooled to provide estimates of the incidence in all hospitalized patients. In our analysis, the original studies were examined by 2 investigators for consistency with the study search and inclusion criteria of the meta-analysis by Lazarou and colleagues, as well as accuracy and appropriateness of data extraction, meta-analysis, and conclusions. RESULTS Multiple sources of heterogeneity among studies and data were found and include important differences in populations and hospital wards monitored, surveillance techniques, ADR definitions, determination of preventability of ADRs, distinguishing relationship to drugs, and in formats of reporting ADRs (by numbers of events or by patients). Imputations of event numerators made by the authors of the original meta-analysis were questionable and may overestimate the results of any individual study. With regard to fatal ADRs, the problem of small numbers of events is likely to introduce large errors in incidence estimates. Simple pooling of fatal event frequencies from only those studies specifically reporting the number of fatal ADRs, as was done in the meta-analysis of Lazarou and colleagues, is likely to dramatically overestimate the death rate. CONCLUSION Meta-analysis was invalid because of heterogeneity of the studies. Most of these studies did not report the data needed for incidence calculations. The methodology used was seriously flawed, and no conclusions regarding ADR incidence rates in the hospitalized population in the United States should be made on the basis of the original meta-analysis.

Abstract
Polyvinyl alcohol-cryogel (PVA-C) is a hydrogel that is an excellent tissue mimic. In order to characterize mass transfer in this material, as well as to demonstrate in principle the ability to noninvasively measure solute diffusion in tissue, we measured the diffusion coefficient of the magnetic resonance (MR) contrast agent gadolinium diethylene triaminopentaacetic acid (Gd-DTPA) through PVA-C using a clinical MR imager. The method involved filling thick-walled rectangular PVA-C "cups" with known concentrations of Gd-DTPA solutions. Then by using a fast inversion recovery spin echo MR imaging protocol, a signal "null" contour was created in the MR image that corresponded to a second, known concentration of Gd-DTPA. By collecting a series of MR images through the PVA-C wall as a function of time, the displacement of this second known isoconcentration contour could be tracked. Application of Fick's second law of diffusion yielded the diffusion coefficient. Seven separate experiments were performed using various combinations of initial concentrations of Gd-DTPA within the PVA-C cups (3.2, 25.6, or 125 mM) and tracked isoconcentrations contours (0.096, 0.182, or 0.435 mM Gd-DTPA). The experimental results and the predictions of Fick's law were in excellent agreement. The diffusivity of Gd-DTPA through 10% PVA hydrogel was found to be (2.6 +/- 0.04) x 10(-10) m(2)/s (mean +/- s.e.m.). Separate permeability studies showed that the diffusion coefficient of Gd-DTPA through this hydrogel did not change with an applied pressure of up to 7.1 kPa. Accurate measurements could be made within 30 min if suitable Gd-DTPA concentrations were selected. Due to the excellent repeatability and fast data acquisition time, this technique is very promising for future in vivo studies of species transport in tissue.

Abstract
Electromyography (EMG) was evaluated as a supplement to clinical examination and biomechanical considerations to optimize forearm donor muscle selection before tendon transfers to 4 functionless hands in 3 patients with slowly progressive polyneuropathies. Two patients had unusually severe Charcot-Marie-Tooth disease; the third patient had idiopathic mononeuropathy multiplex. Standard EMG parameters were used to devise an intuitive muscle grading system, including most importantly interference patterns and motor control, plus motor unit morphology and stability. Given our objective of restoring survivable function despite ongoing polyneuropathy, we found that EMG reveals prognostically important differences among partially denervated candidate muscles that cannot be detected by experienced clinical examiners. Opposition transfer was performed on one hand of each patient. After 39-, 39-, and 51-month follow-up durations, restored opposition was graded as good in these 3 hands. We conclude that EMG provides meaningful guidance in selecting optimal forearm muscles for tendon transfers to hands in the setting of slowly progressive polyneuropathies.

Abstract
While the scope of the clinician-patient relationship in rehabilitation includes the opportunity to provide information on sexuality, all too often this does not occur. This article identifies barriers to providing information on sexuality and makes suggestions for overcoming them. At a preconference workshop, "Sexuality After Spinal Cord Injury: Understanding the Effects of Knowledge and Attitude on Dissemination Practices," held during the Association of Rehabilitation Nurses 22nd Annual Educational Conference, participants explored barriers to providing sexuality information to their patients and ways for nurse managers and staff members to ameliorate their own discomfort and that of their patients. The barriers identified included lack of time, lack of knowledge, personal attitudes about sexuality, and patient lack of readiness. Approaches that can improve the comfort levels of nurse managers and staff include using educational films and written materials, conducting role playing to explore typical patient questions, and initiating conversation about sexuality with patients. Participants' suggestions for increasing patient comfort level included adopting an open and nonjudgmental listening mode, distinguishing between the physical and emotional aspects of sexual issues, and promoting peer counseling.

Abstract
To elucidate further the role of placental membrane fatty acid-binding protein (p-FABPpm) in preferential transfer of maternal plasma long chain polyunsaturated fatty acids (LCPUFA) across the human placenta, direct binding of the purified protein with various radiolabelled fatty acids (docosahexaenoic, arachidonic, linoleic and oleic acids) was investigated. Binding of these fatty acids to the protein revealed that p-FABPpm had higher affinities and binding capacities for arachidonic and docosahexaenoic acids compared with linoleic and oleic acids. The apparent binding capacities (Bmax) values for oleic, linoleic, arachidonic and docosahexaenoic acids were 2.0 +/- 0.14, 2.1 +/- 0.17, 3.5 +/- 0.11, 4.0 +/- 0.10 mol per mol of p-FABPpm whereas the apparent dissociation constant (Kd) values were 1.0 +/- .0.07, 0.73 +/- 0.04, 0.45 +/- 0.03 and 0.4 +/- 0.02 microM, respectively (n=3). In the case of human serum albumin, the Kd and Bmax values for all fatty acids were around 1 microM and 5 mol/mol of protein, respectively. These data provide direct evidence for the role of p-FABPpm in preferential sequestration of maternal arachidonic and docosahexaenoic acids by the placenta for transport to the fetus by virtue of its preferential binding of these fatty acids.

Abstract
The time course of incorporation of [14C]arachidonic acid and [3H]docosahexaenoic acid into various lipid fractions in placental choriocarcinoma (BeWo) cells was investigated. BeWo cells were found to rapidly incorporate exogenous [14C]arachidonic acid and [3H] docosahexaenoic acid into the total cellular lipid pool. The extent of docosahexaenoic acid esterification was more rapid than for arachidonic acid, although this difference abated with time to leave only a small percentage of the fatty acids in their unesterified form. Furthermore, uptake was found to be saturable. In the cellular lipids these fatty acids were mainly esterified into the phospholipid (PL) and the triacyglycerol (TAG) fractions. Smaller amounts were also detected in the diacylglycerol and cholesterol ester fractions. Almost 60% of the total amount of [3H]Docosahexaenoic acid taken up by the cells was esterified into TAG whereas 37% was in PL fractions. For arachidonic acid the reverse was true, 60% of the total uptake was incorporated into PL fractions whereas less than 35% was in TAG. Marked differences were also found in the distribution of the fatty acids into individual phospholipid classes. The higher incorporation of docosahexaenoic acid and arachidonic acid was found in PC and PE, respectively. The greater cellular uptake of docosahexaenoic acid and its preferential incorporation in TAG suggests that both uptake and transport modes of this fatty acid by the placenta to fetus is different from that of arachidonic acid.
