15 mmol/L, low-density lipoprotein cholesterol by 0.12 mmol/L, and high-density lipoprotein cholesterol by 0.07 mmol/L while they can significantly decrease triglycerides by -0.12 mmol/L compared to controls. CONCLUSIONS SGLT2 inhibitors were not associated with increased risk of dyslipidemia. Further trials with longitudinal assessment are needed to assess the effect of SGLT2 inhibitors on trajectories of changes of lipid metabolism. © 2020 John Wiley & Sons Ltd.Discriminative detection of invasive and noninvasive breast cancers is crucial for their effective treatment and prognosis. However, activatable probes able to do so in vivo are rare. Herein, we report an activatable polymeric reporter (P-Dex) that specifically turns on near-infrared (NIR) fluorescent and photoacoustic (PA) signals in response to the urokinase-type plasminogen activator (uPA) overexpressed in invasive breast cancer. P-Dex has a renal-clearable dextran backbone that is linked with a NIR dye caged with an uPA-cleavable peptide substrate. Such a molecular design allows P-Dex to passively target tumors, activate NIR fluorescence and PA signals to effectively distinguish invasive MDA-MB-231 breast cancer from noninvasive MCF-7 breast cancer, and ultimately undergo renal clearance to minimize the toxicity potential. Thus, this polymeric reporter holds great promise for the early detection of malignant breast cancer. © 2020 Wiley-VCH Verlag GmbH & Co.

PATIENTS AND METHODS Men diagnosed with prostate cancer between 1st April 2014 and 2017 in England were identified by the National Prostate Cancer Audit. Administrative hospital data were then used to categorise the type of prostate biopsy and subsequent complications requiring hospital admission. Administrative hospital data were used to identify patients staying overnight immediately after biopsy and those readmitted separately for hospital admissions because of sepsis, urinary retention or haematuria. Procedure related mortality and total length of hospital stay within 30 days was also recorded. Generalised linear models were used to calculate adjusted risk differences (aRD). RESULTS 73,630 men undergoing prostate biopsy were identified. Those having TP biopsy (n=13,723) were more likely to have an overnight hospital stay (12.3% vs 2.4%; aRD 9.7% 95% CI 7.1% to 12.3%), were less likely to be readmitted because of sepsis (1.0% vs 1.4%; aRD -0.4% CI -0.6% to -0.2%), and were more likely to be readmitted with urinary retention (1.9% vs 1.0%; aRD 1.1% CI 0.7% to 1.4%) than those undergoing a TR biopsy (n=59,907). There were no significant differences in the risk of haematuria or mortality. CONCLUSIONS TP biopsy has a lower risk of readmission for sepsis but a higher risk of readmission for urinary retention than TR biopsy. Use of the TP route would prevent one readmission for sepsis in 278 men at the cost of three additional men readmitted for urinary retention. This article is protected by copyright.

The catalytically generated enamine radical cation serves as a carbon radical electrophile that can stereoselectively add to the alkene of an allylic alcohol and initiate ensuing ring-expansion of cyclopropanol or cyclobutanol. This tandem reaction enables the production of a wide range of nonracemic functionalizable α-quaternary-δ-carbonyl cycloketones in high yields and excellent enantioselectivity from simple aldehydes and allylic alcohols. As a key step, the intramolecular reaction was also successfully applied in the asymmetric total synthesis of (+)-cerapicol. © 2020 Wiley-VCH Verlag GmbH & Co.

The underlying assumption is a stationary (time-stable), quasi-linear relationship between tree growth and environment, which however conflicts with basic ecological and evolutionary theory. buy CP-673451 Indeed, our global assessment of the relevant tree-ring literature demonstrates non-stationarity in the majority of tested cases, not limited to specific proxies, environmental parameters, regions or species. Non-stationarity likely represents the general nature of the relationship between tree-growth proxies and environment. Studies assuming stationarity however score 2 times more citations influencing other fields of science and the science-policy interface. To reconcile ecological reality with the application of tree-ring proxies for climate or environmental estimates, we provide a clarification of the stationarity concept, propose a simple confidence framework for the re-evaluation of existing studies and recommend the use of a new statistical tool to detect non-stationarity in tree-ring proxies. Our contribution is meant to stimulate and facilitate discussion in light of our results to help increase confidence in tree-ring based climate and environmental estimates for science, the public and policymakers.

Ecological connectivity is one factor that might influence community structure and ecosystem functioning post drought, by facilitating the recovery of sensitive species via dispersal at both local (e.g. a nearby habitat patch) and regional (from other systems within the same region) scales. In an outdoor mesocosm experiment, we investigated how impacts of drought on boreal stream ecosystems are altered by the spatial arrangement of local habitat patches within stream channels, and variation in ecological connectivity with a regional species pool. We measured basal ecosystem processes underlying carbon and nutrient cycling (i) algal biomass accrual, (ii) microbial respiration and (iii) decomposition of organic matter, and sampled communities of aquatic fungi and benthic invertebrates. An eight-day drought event had strong impacts on both community structure and ecosystem functioning, including algal accrual, leaf decomposition and microbial respiration, with many of these impacts persisting even after water levels had been restored for 3.
