News at a glance: A win for obesity drugs, NIH unionization roadblocks, and Mexican fireflies under threat
CONSERVATION Researchers raise alarm over threat to Mexican fireflies Scientists from the International Union for Conservation of Nature (IUCN) last week delivered a letter to the Mexican government requesting it regulate tourism centered on the threatened firefly species Photinus palaciosi . Endemic to Mexico’s Tlaxcala forests, P. palaciosi is one of the few species that glow in synchrony, offering an annual spectacle that attracts thousands of visitors during summer mating season. The letter describes how littering, artificial light, and noise interfere with the insects’ courtship and eg...

Effects of Normothermic Machine Perfusion Conditions on Mesenchymal Stromal Cells
In this study the effect of NMP perfusion fluid on survival, metabolism and function of thawed cryopreserved human (h)MSC and porcine (p)MSC in suspension conditions was studied. Suspension conditions reduced the viability of pMSC by 40% in both perfusion fluid and culture medium. Viability of hMSC was reduced by suspension conditions by 15% in perfusion fluid, whilst no differences were found in survival in culture medium. Under adherent conditions, survival of the cells was not affected by perfusion fluid. The perfusion fluid did not affect survival of fresh MSC in suspension compared to the control culture medium. The f...

Ibrutinib, lenalidomide, and rituximab in relapsed or refractory mantle cell lymphoma (PHILEMON): a multicentre, open-label, single-arm, phase 2 trial
Publication date: Available online 29 January 2018 Source:The Lancet Haematology Author(s): Mats Jerkeman, Christian Winther Eskelund, Martin Hutchings, Riikka Räty, Karin Fahl Wader, Anna Laurell, Helle Toldbod, Lone Bredo Pedersen, Carsten Utoft Niemann, Christina Dahl, Hanne Kuitunen, Christian H Geisler, Kirsten Grønbæk, Arne Kolstad Background Regimens based on ibrutinib alone and lenalidomide and rituximab in combination show high activity in patients with relapsed or refractory mantle cell lymphoma. We hypothesised that the combination of all three drugs would improve efficacy compared with previously published ...

The effect of physical activity on mortality and cardiovascular disease in 130  000 people from 17 high-income, middle-income, and low-income countries: the PURE study
We examined whether different amounts and types of physical activity are associated with lower mortality and CVD in countries at different economic levels. Methods In this prospective cohort study, we recruited participants from 17 countries (Canada, Sweden, United Arab Emirates, Argentina, Brazil, Chile, Poland, Turkey, Malaysia, South Africa, China, Colombia, Iran, Bangladesh, India, Pakistan, and Zimbabwe). Within each country, urban and rural areas in and around selected cities and towns were identified to reflect the geographical diversity. Within these communities, we invited individuals aged between 35 and 70 years ...

Cardiovascular mortality and morbidity in patients with type 2 diabetes following initiation of sodium-glucose co-transporter-2 inhibitors versus other glucose-lowering drugs (CVD-REAL Nordic): a multinational observational analysis
Publication date: Available online 3 August 2017 Source:The Lancet Diabetes & Endocrinology Author(s): Kåre I Birkeland, Marit E Jørgensen, Bendix Carstensen, Frederik Persson, Hanne L Gulseth, Marcus Thuresson, Peter Fenici, David Nathanson, Thomas Nyström, Jan W Eriksson, Johan Bodegård, Anna Norhammar Background In patients with type 2 diabetes and a high cardiovascular risk profile, the sodium-glucose co-transporter-2 (SGLT2) inhibitors empagliflozin and canagliflozin have been shown to lower cardiovascular morbidity and mortality. Using real-world data from clinical practice, we aimed to compare cardiovas...
