The high variation of BWL in class III obesity might reflect different states of motivation such as the attitude towards bariatric surgery. © 2020 The Authors.

Here, a tailored superhygroscopic hydrogel, a catalyst, and a solar cell are integrated into a humidity digester that can break down ambient moisture into hydrogen and oxygen, creating an efficient electrochemical cell. The function of the hydrogel is to harvest moisture from ambient humidity and transfer the collected water to the catalyst. Barium titanate and vertical 2D MoS2 nanosheets are integrated as the catalyst the negatively polarized cathode can enhance the electron transport and attract H+ to the MoS2 surface for water reduction, while water oxidation takes place at the positively polarized anode. By employing this mechanism, it is possible to maintain the relative humidity in a medium-sized room at less then 60% without any additional energy input, and a stable current of 12.5 mA cm-2 is generated by the humidity digester when exposed to ambient light. © 2020 WILEY-VCH Verlag GmbH & Co.

Interventions developed in the field have still not been sufficient to prevent and relieve children's fear and pain. More knowledge, from children's own perspectives, is needed about how they deal with their experiences. AIM To explore child-identified strategies that children use to manage fear and pain during needle-related medical procedures in hospital. METHODS Interviews with children, age 4-12 years, with experience of hospital care were analysed qualitatively using content analysis. this website RESULTS Children have self-identified strategies for dealing with fear and pain during hospital care and treatment. The strategies vary depending on examination or treatment and on how the child felt at that particular day. Children describe what they can do themselves, how adults can empower them and support from surroundings as strategies that give them a choice and a voice. Children wished to have influence, decide when and how information should be given, scream out loud or squeeze something hard, to deal with fear and pain. The results also show that children tried to be brave, gain control and think positively. Something nice to look at and opportunities to play with others also contributed. CONCLUSIONS Strategies vary between children and are used differently on different occasions. Healthcare professionals pose a threat to the child's needs and ability to use their strategies due to lack of knowledge of the child's chosen strategies. © 2020 The Authors.

The field has quickly expanded in recent years, and several new technologies have been developed that all aim to combine gene expression data with spatial information. The vast array of methodologies displays fundamental differences in their approach to obtain this information, and thus, demonstrate method-specific advantages and shortcomings. While the field is moving forward at a rapid pace, there are still multiple challenges presented to be addressed, including sensitivity, labor extensiveness, tissue-type dependence, and limited capacity to obtain detailed single-cell information. No single method can currently address all these key parameters. In this review, available spatial transcriptomics methods are described and their applications as well as their strengths and weaknesses are discussed. Future developments are explored and where the field is heading to is deliberated upon. © 2020 WILEY Periodicals, Inc.BACKGROUND Upper gastrointestinal bleeding is a common medical emergency associated with substantial mortality. Tranexamic acid may be effective for reducing mortality in upper gastrointestinal bleeding. AIM To examine the effects of tranexamic acid in upper gastrointestinal bleeding by systematic review and meta-analysis. METHODS We searched PubMed, EMBASE, CINAHL, the Cochrane Central Register of Controlled Trials (CENTRAL) and other relevant websites for randomised controlled trials investigating the effect of tranexamic acid published from inception to December 10, 2019. The primary outcome of interest was mortality. Estimates of effect were pooled with a random effects model. Quality of evidence was assessed using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach. RESULTS The search identified 1572 citations. Eleven trials comprising 2076 patients were eligible for inclusion. Of these, 10 trials (2013 patients) compared tranexamic acid with placebo. Risk of death was significantly reduced in patients who received tranexamic acid compared with those who received placebo (RR 0.59, 95% CI 0.43-0.82, P = 0.001) with no significant heterogeneity noted among studies (I2  = 0%, P = 0.81). The GRADE assessment rated the quality of the evidence for mortality as moderate due to risk of bias. There were no statistically significant differences between tranexamic acid and placebo for the prevention of re-bleeding, need for surgical interventions, need for blood transfusions or frequency of thromboembolic events. CONCLUSIONS Moderate-quality evidence shows that tranexamic acid is superior to placebo for the reduction in mortality in patients with upper gastrointestinal bleeding. While our findings lend further support to the use of tranexamic acid for treating patients with upper gastrointestinal bleeding, additional higher-quality trials are needed. © 2020 John Wiley & Sons Ltd.BACKGROUND There have been many single cross-sectional studies on nurse or patient outcomes. However, long-term evidence on improving nurse and patient outcomes is still limited. The High-Quality Care Project is a national project in China for improving nurse and patient outcomes by implementing primary nursing. AIM (1) To assess the long-term changes in nurse and patient outcomes in the context of the High-Quality Care Project. (2) To explore the potential influences of primary nursing on nurse and patient outcomes based on this study and broader existing evidence. METHODS The data of two cross-sectional studies were used for analysis. The two cross-sectional studies were conducted before (2009) and after (2016) the High-Quality Care Project. A total of 1376 nurses and 904 patients from 40 units of 10 tertiary hospitals were surveyed. Reliable and validated instruments were used to measure nurse and patient outcomes. Multilevel modelling was the main method for data analysis. RESULTS Nurses in 2016 were more satisfied than nurses in 2009 with most dimensions of nurse work environment and job satisfaction.
