- Reduced-intensity conditioning (RIC) allogeneic haematopoietic cell transplantation (allo-HCT) is a curative option for select relapsed/refractory Hodgkin lymphoma (HL) patients; however, there are sparse data to support superiority of any particular conditioning regimen. We analyzed 492 adult patients undergoing human leucocyte antigen (HLA)-matched sibling or unrelated donor allo-HCT for HL between 2008 and 2016, utilizing RIC with either fludarabine/busulfan (Flu/Bu), fludarabine/melphalan (Flu/Mel140) or fludarabine/cyclophosphamide (Flu/Cy). Multivariable regression analysis was performed using a significance level of <0 center dot 01. There were no significant differences between regimens in risk for non-relapse mortality (NRM) (P = 0 center dot 54), relapse/progression (P = 0 center dot 02) or progression-free survival (PFS) (P = 0 center dot 14). Flu/Cy conditioning was associated with decreased risk of mortality in the first 11 months after allo-HCT (HR = 0 center dot 28; 95% CI = 0 center dot 10-0 center dot 73; P = 0 center dot 009), but beyond 11 months post allo-HCT it was associated with a significantly higher risk of mortality, (HR = 2 center dot 46; 95% CI = 0 center dot 1.32-4 center dot 61; P = 0 center dot 005). Four-year adjusted overall survival (OS) was similar across regimens at 62% for Flu/Bu, 59% for Flu/Mel140 and 55% for Flu/Cy (P = 0 center dot 64), respectively. These data confirm the choice of RIC for allo-HCT in HL does not influence risk of relapse, NRM or PFS. Although no OS benefit was seen between Flu/Bu and Flu/Mel 140; Flu/Cy was associated with a significantly higher risk of mortality beyond 11 months from allo-HCT (possibly due to late NRM events).

- This article tests the hypothesis on whether tourism is an important institutional factor in reconciling the conflicting goals of conservation and development. The study entails data from field surveys across protected areas including the Serengeti National Park and the Ngorongoro Conservation Area in northern Tanzania, and the Corbett National Park in northern India. With human development defined in terms of stages of progress (SOP) delineated by the respondents themselves, the study finds indicative evidences of the validity of the posed hypothesis in the two nations, in varying proportions. Factors not related to tourism, like incomes from livestock, have affected development in Tanzania, though not in India.

- Chronic lymphocytic leukemia (CLL) is a common hematologic malignancy with many highly effective therapies. Chemorefractory disease, often characterized by deletion of chromosome 17p, has historically been associated with very poor outcomes, leading to the application of allogeneic hematopoietic stem cell transplantation (allo-HCT) for medically fit patients. Although the use of allo-HCT has declined since the introduction of novel targeted therapy for the treatment of CLL, there remains significant interest in understanding factors that may influence the efficacy of allo-HCT, the only known curative treatment for CLL. The potential benefit of transplantation is most likely due to the presence of alloreactive donor T cells that mediate the graft-versus-leukemia (GVL) effect. The recognition of potentially tumor-specific antigens in the context of class I and II major histocompatibility complex on malignant B lymphocytes by donor T cells may be influenced by subtle differences in the highly polymorphic HLA locus. Given previous reports of specific HLA alleles impacting the incidence of CLL and the clinical outcomes of allo-HCT for CLL, we sought to study the overall survival and progression-free survival of a large cohort of patients with CLL who underwent allo-HCT from fully HLA-matched related and unrelated donors at Center for International Blood and Marrow Transplant Research transplantation centers. We found no statistically significant association of allo-HCT outcomes in CLL based on previously reported HLA combinations. Additional study is needed to further define the immunologic features that portend a more favorable GVL effect after allo-HCT for CLL.

- Introduction: The use of medications in the general population has increased over time. Information on active metabolite concentrations for common drugs in the general population is limited. Recent advances in metabolomic technologies have made high-throughput profiling of many active metabolites in large epidemiological cohorts increasingly feasible.Aim: 1. Prospective assessment of the proportion of measurable active metabolite levels of major drugs in the general population using mass spectrometry. 2. Relation of cardiovascular (CV) drugs with inadequate risk factor control and CV disease.Methods: Assessment of CV risk factors by coronary CT angiography and carotid ultrasound imaging in a large prospective cohort of 6,251 individuals randomly selected from the general population in Malmö, Sweden (age 50-64 years). Untargeted metabolomic profiling of fasting plasma was performed by Metabolon, USA in a random subset of 3,986 subjects.Results: Intake of at least one prescribed drug was reported in 1840 subjects (46%). Combination drugs were reported in 249 subjects (6%). The most common drug classes reported were lipid-lowering (n=369, 9% of which most were statins), beta blockers (n=307, 8%), ARB (n=272, 7%), and ACE inhibitors (268, 7%), followed by levothyroxine, CCB, antidepressants, glucocorticoids, PPI, antidiabetic, bronchodilators and diuretics. For major CV drugs, detectable active metabolite levels ranged from 54% (atorvastatin and enalapril) to 96% (metoprolol and metformin). Non-detectable levels of lipid-lowering, antihypertensive, and antidiabetic drugs were associated with higher LDL, cholesterol, BP and glucose, although only antidiabetic drugs were significant (p<0.05). Non-detectable levels of lipid-lowering and antihypertensive drugs were also non-significantly associated with increased coronary calcium and carotid plaque.Conclusion: Our study provides an overview of the distribution of common drugs with detectable levels in a contemporary Swedish population. Pharmacometabolomic profiling revealed that non-measurable levels of common CV drugs were associated with lower risk factor control and non-significant trends towards more atherosclerotic disease by imaging in a substantial number of subjects.

- Purpose: To develop a prognostic model and cytogenetic risk classification for previously treated patients with chronic lymphocytic leukemia (CLL) undergoing reduced intensity conditioning (RIC) allogeneic hematopoietic cell transplantation (HCT).Experimental Design: We performed a retrospective analysis of outcomes of 606 patients with CLL who underwent RIC allogeneic HCT between 2008 and 2014 reported to the Center for International Blood and Marrow Transplant Research.Results: On the basis of multivariable models, disease status, comorbidity index, lymphocyte count, and white blood cell count at HCT were selected for the development of prognostic model. Using the prognostic score, we stratified patients into low-, intermediate-, high-, and very-high-risk [4-year progression-free survival (PFS) 58%, 42%, 33%, and 25%, respectively, P < 0.0001; 4-year overall survival (OS) 70%, 57%, 54%, and 38%, respectively, P < 0.0001]. We also evaluated karyotypic abnormalities together with del(17p) and found that del(17p) or >= 5 abnormalities showed inferior PFS. Using a multivariable model, we classified cytogenetic risk into low, intermediate, and high (P < 0.0001). When the prognostic score and cytogenetic risk were combined, patients with low prognostic score and low cytogenetic risk had prolonged PFS (61% at 4 years) and OS (75% at 4 years).Conclusions: In this large cohort of patients with previously treated CLL who underwent RIC HCT, we developed a robust prognostic scoring system of HCT outcomes and a novel cytogenetic-based risk stratification system. These prognostic models can be used for counseling patients, comparing data across studies, and providing a benchmark for future interventions. For future study, we will further validate these models for patients receiving targeted therapies prior to HCT.

- Autologous (auto-) and allogeneic (allo-) hematopoietic cell transplantation (HCT) are accepted treatment modalities in contemporary treatment algorithms for mantle cell lymphoma (MCL). Chimeric antigen receptor (CAR) T cell therapy recently received approval for MCL; however, its exact place and sequence in relation to HCT remain unclear. The American Society of Transplantation and Cellular Therapy, Center of International Blood and Marrow Transplant Research, and the European Society for Blood and Marrow Transplantation jointly convened an expert panel to formulate consensus recommendations for role, timing, and sequencing of auto-HCT, allo-HCT, and CAR T cell therapy for patients with newly diagnosed and relapsed/refractory (R/R) MCL. The RAND-modified Delphi method was used to generate consensus statements. Seventeen consensus statements were generated, with a few key statements as follows: in the first line setting, auto-HCT consolidation represents standard of care in eligible patients, whereas there is no clear role of allo-HCT or CAR T cell therapy outside of clinical trials. In the R/R setting, the preferential option is CAR T cell therapy, especially in patients with MCL failing or intolerant to at least one Bruton's tyrosine kinase inhibitor, while allo-HCT is recommended if CAR T cell therapy fails or is infeasible. Several recommendations were based on expert opinion, where the panel developed consensus statements for important real-world clinical scenarios to guide clinical practice. In the absence of contemporary evidence-based data, the panel found RAND-modified Delphi methodology effective in providing a formal framework for developing consensus recommendations for the timing and sequence of cellular therapies for MCL.
