Several bee species are experiencing significant population declines. As bees exclusively rely on pollen for development and survival, such declines could be partly related to changes in their host plant abundance and quality. Here, we investigate whether generalist bumblebee species, with stable population trends over the past years, adapted their diets in response to changes in the distribution and chemical quality of their pollen resources. We selected five common species of bumblebee in NW Europe for which we had a precise description of their pollen diet through two time periods (‘prior to 1950’ and ‘2004–2005’). For each species, we assessed whether the shift in their pollen diet was related with the changes in the suitable area of their pollen resources. Concurrently, we evaluated whether the chemical composition of pollen resources changed over time and experimentally tested the impact of new major pollen species on the development of B. terrestris microcolonies. Only one species (i.e. B. lapidarius) significantly included more pollen from resources whose suitable area expanded. This opportunist pattern could partly explain the expansion of B. lapidarius in Europe. Regarding the temporal variation in the chemical composition of the pollen diet, total and essential amino acid contents did not differ significantly between the two time periods while we found significant differences among plant species. This result is driven by the great diversity of resources used by bumblebee species in both periods. Our bioassay revealed that the shift to new major pollen resources allowed microcolonies to develop, bringing new evidence on the opportunist feature of bumblebee in their diets. Overall, this study shows that the response to pollen resource drift varies among closely related pollinators, and a species-rich plant community ensures generalist species to select a nutrient-rich pollen diet. © 2016 John Wiley & Sons Ltd [less ▲]

Objective: Although cancer patients frequently experience self-perceived burden to others, this perception has not been enough studied. The aim of this study was to investigate the prevalence of selfperceived burden to the primary caregiver (SPB-PC) and associated factors in an older patient population with hematologic malignancies at the time of chemotherapy initiation. Methods: In total, 166 consecutive patients with hematologic malignancies aged ≥65 years were recruited at the time of chemotherapy initiation. Patients’ SPB-PC was assessed using a 100-mm visual analogue scale (VAS). Characteristics potentially associated with SPB-PC, including sociodemographic and medical characteristics, physical functioning status (Karnofsky performance score, activities of daily living (ADL)/instrumental ADL), symptoms (fatigue, pain, nausea, quality of life), psychological distress (Hospital Anxiety and Depression Scale (HADS)), perceived cognitive function (Functional Assessment of Cancer Therapy Cognitive (FACT-Cog) Scale), and patients’/primary caregivers’ personal relationship characteristics (family tie, support), were assessed. Results: Thirty-five percent of patients reported moderate to severe SPB-PC (VAS ≥ 50 mm). Patients’ SPB-PC was associated with lower Karnofsky performance (β = 0.135, p = 0.058) and ADL (β = 0.148, p = 0.037) scores, and higher HADS (β = 0.283, p<0.001) and FACT-Cog perceived cognitive impairments subscale (β = 0.211, p = 0.004) scores. The proportion of explained variance was 23.5%. Conclusions: Health care professionals should be aware that about one third of older cancer patients experience moderate to severe SPB-PC at the time of chemotherapy initiation. They should adapt their support of patients who report such a feeling. [less ▲]

The genomic profile of multiple myeloma (MM) has prognostic value by dividing patients into a good prognosis hyperdiploid group and a bad prognosis non-hyperdiploid group with a higher incidence of IgH translocations. This classification, however, is inadequate and many other parameters like mutations, epigenetic modifications and genomic heterogeneity may influence the prognosis. We performed a genomic study by array-based comparative genomic hybridization (aCGH) on a cohort of 162 patients to evaluate the frequency of genomic gains and losses. We identified a high frequency of X chromosome alterations leading to partial Xq duplication, often associated with Xi deletion in female patients. This partial X duplication could be a cytogenetic marker of aneuploidy as it is correlated with a high number of chromosomal breakages. Patient with high level of chromosomal breakage had reduced survival regardless the region implicated. A higher transcriptional level was shown for genes with potential implication in cancer and located in this altered region. Among these genes, IKBKG and IRAK1 are members of the NFKB pathway which plays an important role in MM and is a target for specific treatments. [less ▲]

In this retrospective analysis we evaluated the outcome of 313 patients aged ≥ 70 years in the registry of the European Group for Blood and Marrow Transplantation with myelodysplastic syndrome (MDS; n = 221) and secondary acute myeloid leukemia (n = 92) who underwent allogeneic hematopoietic stem cell transplantation (HSCT) from related (n = 79) or unrelated (n = 234) donors. Median age at HSCT was 72 years (range, 70 to 78). Conditioning regimen was nonmyeloablative (n = 54), reduced intensity (n = 207), or standard intensity (n = 52). Allogeneic HSCT for MDS patients ≥ 70 years was increasingly performed over time. Although during 2000 to 2004 only 16 patients received HSCT, during 2011 to 2013 the number of transplantations increased to 181. The cumulative incidence of nonrelapse mortality at 1 year and relapse at 3 years was 32% and 28%, respectively, with a 3-year overall survival rate of 34%. Good performance, determined by Karnofsky performance status, and recipients’ seronegativity for cytomegalovirus was associated with 3-year estimated overall survival rates of 43% (P = .01) and 46% (P = .002), respectively. Conditioning intensity did not impact survival. After careful patient selection, allogeneic HSCT can be offered to patients older than 70 years with MDS. [less ▲]

Background Inflammatory bowel diseases (IBD) are chronic relapsing diseases in which pro-inflammatory immune cells and cytokines induce intestinal tissue damage and disability. Mesenchymal stromal cells (MSCs) exert powerful immunomodulatory effects and stimulate tissue repair. Aim To review the current data on mesenchymal stromal cell therapy in IBD. Method We searched PubMed and ‘ClinicalTrials.gov’ databases using the terms ‘mesenchymal stromal cells’, ‘mesenchymal stem cell transplantation’, ‘inflammatory bowel diseases’, ‘Crohn disease’ and ‘colitis, ulcerative’. Additional publications were identified from individual article reference lists. Results MSCs include inhibition of Th1/Th17 lymphocytes and recruitment of regulatory T lymphocytes, induction of antigen-presenting cells into a regulatorylike profile, and stimulation of epithelial cell differentiation and proliferation. More than 200 patients with refractory fistulas have been treated with local injections of MSCs, resulting in complete response in more than half, and in overall response in approximately two thirds of patients. In refractory luminal Crohn’s disease, 49 cases of systemic MSC infusions have been reported, while trials with autologous MSCs resulted in mitigated responses, studies using allogeneic MSCs were promising, with around 60% of patients experiencing a response and around 40% achieving clinical remission. Conclusions Mesenchymal stromal cells might represent a promising therapy for IBD, especially for Crohn’s disease. There remain many unsolved questions concerning the optimal origin and source of mesenchymal stromal cells, dosage and modalities of administration. Moreover, mesenchymal stromal cells still need to prove their effectiveness compared with conventional treatments in randomised controlled trials. [less ▲]

It has been postulated that memories of neardeath experiences (NDEs) could be (at least in part) reconstructions based on experiencers’ (NDErs) previous knowledge and could be built as a result of the individual’s attempt to interpret the confusing experience. From the point of view of the experiencer, NDE memories are perceived as being unrivalled memories due to its associated rich phenomenology. However, the scientific literature devoted to the cognitive functioning of NDErs in general, and their memory performance in particular, is rather limited. This study examined NDErs’ susceptibility to false memories using the Deese–Roediger–McDermott (DRM) paradigm. We included 20 NDErs who reported having had their experience in the context of a life-threatening event (Greyson NDE scale total score ≥7/32) and 20 volunteers (matched for age, gender, education level, and time since brain insult) who reported a life-threatening event but without a NDE. Both groups were presented with DRM lists for a recall task during which they were asked to assign “Remember/Know/Guess” judgements to any recalled response. In addition, they were later asked to complete a post-recall test designed to obtain estimates of activation and monitoring of critical lures. Results demonstrated that NDErs and volunteers were equally likely to produce false memories, but that NDErs recalled them more frequently associated with compelling illusory recollection. Of particular interest, analyses of activation and monitoring estimates suggest that NDErs and volunteers groups were equally likely to think of critical lures, but source monitoring was less successful in NDErs compared to volunteers.

The induction of alcohol craving and the cognitive processing of alcohol-related stimuli in alcohol-dependent patients have been reported to compete with inhibitory control and contribute to alcohol relapse. The aim of the present study is to investigate whether the induction of a craving state, using an alcohol cue exposure paradigm, influences response inhibition towards both neutral stimuli and alcohol-related stimuli in alcohol-dependent patients. Thirty-one detoxified alcohol-dependent patients were exposed to either their preferred alcoholic beverage or to a glass of water. They then performed a modified stop signal task, which used alcohol-related words, neutral words and non-words, and a lexical decision as the Go response. The alcohol-cue exposure group reported significantly higher alcohol craving and showed higher percentages of commission errors towards alcohol-related words than the control group. All participants, but especially those of the alcohol-cue exposure group, showed also shorter reaction times when alcohol words were used as targets in go trials. The induction of alcohol craving in detoxified alcohol-dependent patients increases the motivational salience value of alcohol stimuli, leading them to automatically approach alcohol-related cues and therefore impairing response inhibition towards those stimuli.
