- Motivation: The BioTIME database contains raw data on species identities and abundances in ecological assemblages through time. These data enable users to calculate temporal trends in biodiversity within and amongst assemblages using a broad range of metrics. BioTIME is being developed as a community-led open-source database of biodiversity time series. Our goal is to accelerate and facilitate quantitative analysis of temporal patterns of biodiversity in the Anthropocene. Main types of variables included: The database contains 8,777,413 species abundance records, from assemblages consistently sampled for a minimum of 2 years, which need not necessarily be consecutive. In addition, the database contains metadata relating to sampling methodology and contextual information about each record. Spatial location and grain: BioTIME is a global database of 547,161 unique sampling locations spanning the marine, freshwater and terrestrial realms. Grain size varies across datasets from 0.0000000158 km(2) (158 cm(2)) to 100 km(2) (1,000,000,000,000 cm(2)). Time period and grainBio: TIME records span from 1874 to 2016. The minimal temporal grain across all datasets in BioTIME is a year. Major taxa and level of measurement: BioTIME includes data from 44,440 species across the plant and animal kingdoms, ranging from plants, plankton and terrestrial invertebrates to small and large vertebrates.

- After subarachnoid haemorrhage, prolonged exposure to toxic extracellular haemoglobin occurs in the brain. Here, we investigate the role of haemoglobin neurotoxicity in vivo and its prevention. In humans after subarachnoid haemorrhage, haemoglobin in cerebrospinal fluid was associated with neurofilament light chain, a marker of neuronal damage. Most haemoglobin was not complexed with haptoglobin, an endogenous haemoglobin scavenger present at very low concentration in the brain. Exogenously added haptoglobin bound most uncomplexed haemoglobin, in the first 2 weeks after human subarachnoid haemorrhage, indicating a wide therapeutic window. In mice, the behavioural, vascular, cellular and molecular changes seen after human subarachnoid haemorrhage were recapitulated by modelling a single aspect of subarachnoid haemorrhage: prolonged intrathecal exposure to haemoglobin. Haemoglobin-induced behavioural deficits and astrocytic, microglial and synaptic changes were attenuated by haptoglobin. Haptoglobin treatment did not attenuate large-vessel vasospasm, yet improved clinical outcome by restricting diffusion of haemoglobin into the parenchyma and reducing small-vessel vasospasm. In summary, haemoglobin toxicity is of clinical importance and preventable by haptoglobin, independent of large-vessel vasospasm.

- This is a plain language summary of an article originally published in The New England Journal of Medicine. It is about initial results (collected in October 2019) from the JAVELIN Bladder 100 study (a clinical trial), which looked at avelumab maintenance treatment in people with advanced urothelial cancer. Urothelial cancer is the most common type of bladder cancer. People with advanced urothelial cancer often receive chemotherapy. If this is the first treatment people with advanced disease are given, it is called first-line treatment. If the cancer stops growing or shrinks with first-line chemotherapy, people can be given different treatment to try to prevent the cancer from growing again. This is called maintenance treatment. It may help people live longer. What happened in the JAVELIN Bladder 100 study? In the JAVELIN Bladder 100 study, researchers wanted to find out if maintenance treatment with avelumab would help people with advanced urothelial cancer live longer. Avelumab is a type of medicine called immunotherapy. Immunotherapy helps the body's immune system fight cancer. 700 people took part in the study. To take part, they must have already been treated with first-line chemotherapy. Also, their cancer must have shrunk or not grown with this treatment. They were then treated with either avelumab maintenance treatment plus best supportive care or best supportive care alone. Best supportive care means treatments that help improve symptoms and quality of life. These treatments do not affect the cancer directly and can include medicines to relieve pain. What were the results? Researchers found that people treated with avelumab maintenance treatment plus best supportive care lived, on average, 7 months longer than people who received best supportive care alone. People treated with avelumab had more side effects than those not treated with avelumab, but most were not severe. Common side effects with avelumab included persistent tiredness, itchy skin, urinary tract infection, and diarrhea. What do the results of the study mean? Results from the JAVELIN Bladder 100 study support the use of avelumab as maintenance treatment for people with advanced urothelial cancer whose cancer has shrunk or not grown with first-line chemotherapy.
