The aim of this study was to investigate transitions between factory-made (FM) cigarettes and RYO in a longitudinal sample of European smokers, and their perceptions of relative harmfulness and knowledge of health effects. METHODS We used data collected from the EUREST-PLUS ITC 6 European Country (6E) Surveys in 2016 (n = 6011 smokers) and in 2018 (n = 6027) in Germany, Greece, Hungary, Poland, Romania and Spain. A total of 3195 cohort respondents were interviewed in both years. Use of RYO and FM, knowledge of health effects of smoking as well as perceptions about RYO were assessed. We used logistic regression models to explore sociodemographic correlates of transitions from one product to the other, of perceptions and knowledge related to smoking health effects. RESULTS Approximately 7.4% of exclusive FM smokers transitioned to RYO and 29.5% of exclusive RYO smokers transitioned to FM cigarettes from 2016 to 2018. RYO use in 2018 was more frequent among smokers of low education and income, but none of these factors were associated with transitions. Most RYO smokers perceived RYO as cheaper than FM and 21.7% of them considered RYO to be less harmful than FM. Knowledge of the health effects of smoking was not associated with type of product smoked. CONCLUSIONS RYO is popular among European smokers; its lower cost seems to be a major factor for RYO users; reasons for transitions to and from RYO are less clear and need to be further investigated. © The Author(s) 2020.

The impact of LAG3 digital gene expression was tested in 309 patients with DLBCL treated with standard chemoimmunotherapy. Cellular distribution of LAG3 protein was determined by immunohistochemistry and flow cytometry. In tumor-infiltrating lymphocytes (TILs), LAG3 expression was highest on CD4+ regulatory T cells (Tregs) and was also highly expressed on CD8+ T cells compared with CD4+ non-Tregs (both P = .008). LAG3high TILs were enriched in PD-1 and TIM-3. LAG3 was also expressed on a proportion of malignant B cells, and these patients had significantly higher LAG3 messenger RNA in their biopsies (P = .03). LAG3high gene expression was associated with inferior survival in discovery/validation cohorts, independent of cell of origin and the international prognostic index. Patients who were PD-L1high were fivefold more likely to be LAG3high (P less then .0001). Patients who were LAG3high/PD-L1high had an inferior progression-free survival (P = .011) and overall survival (P = .005) compared with patients who were LAG3low/PD-L1high. Digital spatial protein analysis confirms LAG3 expression on T cells and, surprisingly, tumor-associated macrophages (TAMs) at higher levels than found on CD20+ B cells in the tumor microenvironment. LAG3 is frequently expressed on CD4+ Tregs and CD8+ TILs, typically with other immune checkpoints, and is also present in a proportion of malignant B cells in DLBCL and in areas enriched for TAMs. LAG3high expression is associated with poor outcome independent of conventional prognosticators. © 2020 by The American Society of Hematology.Primary vitreoretinal lymphoma (PVRL) is a high-grade lymphoma affecting the vitreous and/or the retina. The vast majority of cases are histopathologically classified as diffuse large B-cell lymphoma (DLBCL) and considered a subtype of primary central nervous system lymphoma (PCNSL). To obtain more insight into the ontogenetic relationship between PVRL and PCNSL, we adopted an immunogenetic perspective and explored the respective immunoglobulin gene repertoire profiles from 55 PVRL cases and 48 PCNSL cases. In addition, considering that both entities are predominantly related to activated B-cell (ABC) DLBCL, we compared their repertoire with that of publicly available 262 immunoglobulin heavy variable domain gene rearrangement sequences from systemic ABC-type DLBCLs. PVRL displayed a strikingly biased repertoire, with the IGHV4-34 gene being used in 63.6% of cases, which was significantly higher than in PCNSL (34.7%) or in DLBCL (30.2%). LY3009120 inhibitor Further repertoire bias was evident by (1) restricted associations of IGHV4-34 expressing heavy chains, with κ light chains utilizing the IGKV3-20/IGKJ1 gene pair, including 5 cases with quasi-identical sequences, and (2) the presence of a subset of stereotyped IGHV3-7 rearrangements. All PVRL IGHV sequences were highly mutated, with evidence of antigen selection and ongoing mutations. Finally, half of PVRL and PCNSL cases carried the MYD88 L265P mutation, which was present in all 4 PVRL cases with stereotyped IGHV3-7 rearrangements. In conclusion, the massive bias in the immunoglobulin gene repertoire of PVRL delineates it from PCNSL and points to antigen selection as a major driving force in their development. © 2020 by The American Society of Hematology.Multiple models of donor killer immunoglobulin receptor (KIR) alloreactivity or KIR genotype have been reported to be protective against leukemia relapse after allogeneic transplantation. However, few studies have addressed this topic in the pediatric population. Here, we assessed the outcomes of allogeneic transplantation in children with acute lymphoblastic leukemia (ALL; n = 372) or acute myeloid leukemia (AML; n = 344) who received unrelated donor (URD) transplantation and were reported to the Center for International Blood and Marrow Transplant Research (CIBMTR) from 2005 to 2016. As expected in this pediatric population, most patients underwent myeloablative conditioning while in remission and with bone marrow as a stem cell source. We tested KIR ligand mismatch, KIR gene content (centromeric [Cen] B), KIR2DS1 mismatching, and Cen B/telomeric A using Cox regression models and found that none were significantly associated with either relapse or disease-free survival when considering the entire cohort of patients (ALL and AML), AML, or ALL separately.
