BACKGROUND Hydrocephalus requiring external ventricular drainage is common following aneurysmal subarachnoid hemorrhage (aSAH). Timing and strategy for the discontinuation of the external ventricular drain (EVD) are, however, controversial as guidelines are based on limited scientific evidence. A recent similar survey showed that guidelines and recommendations are not being followed. We conducted a questionnaire survey regarding the management of EVD treatment in patients with aSAH and investigated current treatment practice, consensus, and adherence to guidelines within the neurosurgical departments in Scandinavia. METHODS A questionnaire concerning the management of EVD discontinuation in patients with hydrocephalus following aSAH was distributed to all 14 neurosurgical departments in Scandinavia (Norway, Sweden, and Denmark). Neurosurgeons and neurosurgical trainees at all levels were asked to complete the questionnaire individually. A total of 175 completed questionnaires were received between May 2018 anensus at department level was absent. Initiation of the discontinuation process appeared to be case dependent and mainly influenced by the patients' clinical condition and drainage volume. GCS was the clinical variable considered most important when deciding on the initiation of EVD discontinuation.AIMS AND OBJECTIVES To review the available literature regarding the use of prostate cancer-related mobile phone applications (PCA). MATERIALS AND METHODS The search was for English language articles between inceptions of databases to June 2019. Medline, EMBASE, Cochrane Library, CINAHL and Web of Science were searched. Full-text articles were reviewed, and the following data were extracted to aid with app analysis name of application, developer, platform (Apple App Store or Google Play Store) and factors assessed by the article. RESULTS The search yielded 1825 results of which 13 studies were included in the final review. 44 PCAs were identified from the data collected of which 59% of the PCAs had an educational focus. 11 apps were inactive and 5 weren't updated within the last year. Five studies focused on the development and testing of apps (MyHealthAvatar, CPC, Rotterdam, Interaktor, NED). Two studies evaluated the readability of PCAs. Most PCAs had a reading level greater than that of the average patient. Two studies evaluated the quality and accuracy of apps. Majority of PCAs were accurate with a wide range of information. The study reported most PCAs to have deficient or insufficient scores for data protection. Two studies evaluated the accuracy of Rotterdam, CORAL and CPC risk calculators. Rotterdam was the best performer. CONCLUSIONS PCAs are currently in its infancy and do require further development before widespread integration into existing clinical practise. There are concerns with data protection, high readability standards and lack of information update in current PCAs. If developed appropriately with responsible governance, they do have the potential to play important roles in modern-day prostate cancer management.STUDY DESIGN Retrospective cohort study. OBJECTIVES To investigate the effects of 200-unit onabotulinumtoxin A detrusor injections on neurogenic detrusor overactivity (NDO) in patients who have previously been treated with 300-unit injections. SETTING Tertiary urologic referral center in Switzerland. METHODS The patient database was screened for patients with NDO as a result of chronic (≥ 12 months) spinal cord injury (SCI), who had been treated with 300- followed by 200-unit onabotulinumtoxin A detrusor injections. Patient characteristics, bladder management data and concurrent bladder medication as well as urodynamic data were collected. The percent changes in the urodynamic parameters from the 300- to the 200-unit treatment phase were calculated to test for non-inferiority of the 200-unit treatment. RESULTS The data of 61 individuals with a mean age of 44 ± 15 years (range 18-73 years) and a mean 13.2 ± 9.5 years (range 2-43 years) since SCI were analyzed. The 200-unit treatment was not inferior regarding the urodynamic parameters compared to the 300-unit treatment. Furthermore, the proportion of patients with urinary incontinence was similar for both doses. There was no significant difference in the number of daily bladder evacuations (p = 0.13) or used incontinence pads (p = 0.43) between the two dosage phases. Moreover, there was no significant (p = 0.19) increase in the use of concurrent NDO medication (antimuscarinics or mirabegron) during the 200-unit treatment. CONCLUSIONS The treatment of NDO with 200 units of onabotulinumtoxin A was not inferior to a 300-unit treatment regarding urodynamic parameters in patients with chronic SCI.A competitive immunochromatographic assay (ICA) is presented and used for on-site determination of ractopamine (RAC). Ultramarine blue nanoparticles were directly separated from ultramarine blue industrial products by centrifugation ( 4000 rpm) and used as visible labels in ICAs. The ultramarine blue nanoparticles were coated by polyacrylic acid (PAA), which provides carboxyl groups on the surface of ultramarine blue nanoparticles. An anti-RAC monoclonal antibody (mAb) was covalently immobilized on the carboxyl-modified ultramarine blue nanoparticle surface via diimide-activated conjugation between the carboxyl groups on the ultramarine blue nanoparticle surface and the amino groups of the antibodies. RAC and BSA-modified RAC competitively bind to the anti-RAC mAb on the ultramarine blue nanoparticles. The blue band in the test line is generated by the accumulation of ultramarine blue nanoparticles and is negatively associated with the RAC content. Under optimal conditions, the visual limit of detection (vLOD) of this ICA for RAC is 2.0 ng mL-1, 2.0 ng mL-1, and 1.0 ng mL-1 in phosphate-buffered saline (PBS), feed samples, and pork samples, respectively. The ultramarine blue nanoparticle-based ICA also shows no cross activity with salbutamol, clorprenaline, clenbuterol, or terbutaline. Graphical abstract Schematic representation of the ultramarine blue nanoparticles immunochromatographic assay for detection of ractopamine (RAC) based on competitive method. The ultramarine blue nanoparticles were screened from commercial ultramarine pigments for the first time and used to detect ractopamine.At the beginning of the 21st century, a new deadly infectious disease known as severe acute respiratory syndrome (SARS) was recognized as a global public health threat. Subsequently, ten years after the initial SARS cases occurred in 2002, new cases of another atypical respiratory disease caused worldwide concern. This disease became known as Middle East respiratory syndrome (MERS) and was even more lethal than SARS. Currently, history has repeated itself with the emergence of a new Chinese epidemic at the end of 2019. For this respiratory disease, called COVID-19, a novel coronavirus (SARS-CoV-2) was identified as the etiologic agent. In sum, SARS, MERS and COVID-19 are caused by recently discovered coronaviruses that cause flu-like illnesses, but with a clinical outcome that tends to be more severe. As a result of the current importance of coronaviruses in global public health, we conducted a review to summarize and update, above all, the epidemiological historical aspects of the three major diseases in humans caused by coronaviral infection.During bioleaching of Cobalt from waste lithium-ion batteries, the biooxidation activity of acidophilic bacteria is inhibited by a high concentration of Co ion in the liquid phase. However, the mechanism for Co2+ toxicity to acidophilic bacteria has not been fully elucidated. In this study, the effects of Co2+ concentration on the biooxidation activity for Fe2+, intracellular reactive oxygen species (ROS) level and antioxidant defense systems in a mixed-culture of acidophilic bacteria (MCAB) were investigated. The results showed that the biooxidation activity of the MCAB was inhibited by Co2+. Furthermore, it was indicated that the intracellular ROS contents of the MCAB under conditions of 0.4 M and 0.6 M Co2+ were 2.60 and 3.34 times higher than that under the condition of 0 M Co2+. The increase in intracellular malondialdehyde content indicated that the oxidative damage was induced by Co2+. Selleckchem DDR1-IN-1 Moreover, the antioxidant systems in MCAB were affected by Co2+. It was observed that the Co2+ exposure increased the catalase and glutathione peroxidase activities while reducing the superoxide dismutase activity and the intracellular glutathione (GSH) content. It was found that an exogenous GSH supplementation eliminated excess intracellular ROS and improved the biooxidation activity of the MCAB.Multiple factors including natural and human-induced ones lead to land cover change in the landscape. Therefore, identifying the pattern of land cover change can help inform land-use management and prevent associated issues which can affect the natural resources of the landscape. The aim of this study is to assess land cover change in the Qeshm Island in southern Iran by combining the resulting outputs of multiple modeling methods, cellular automata (CA), Markov chains, and artificial neural networks (ANN) based on land cover maps for the years 1996, 2006, and 2016 that have been extracted from satellite imagery (Landsat 5, 7, and 8). In order to evaluate the accuracy of modeling, the Kappa coefficient was calculated to be 0.8. Then, land cover changes for 2025 were predicted by a hybrid model (CA-Markov-ANN). The results indicate that the classes of built-up areas, vegetation, and mangrove forests have changed more significantly from 1996 to 2016 compared with other classes. Land cover maps generated in this study showed that built-up areas have grown significantly in recent decades due to the region's growing population and development of ports, commercial, and industrial areas. Due to the climate change, the land area covering vegetation has decreased dramatically. The size of the mangrove forests has increased over the time period of the study (1996-2025). The findings of this study can inform land-use planning decisions by providing them with a comprehensive overview of land cover conditions in the future.Ponds, as landscape features, are known to regulate climate. Since ponds proliferate or recede due to natural or anthropogenic factors, a variation of pond numbers implies a variation of their climatic effect. Accordingly, this study investigates the impact of ponds on the local climate of the French Claise watershed. The latter was chosen because it contains a pond dense zone and a pondless zone. This repartition makes the Claise an adequate context to reveal the climatic impact of ponds even in the same landscape. To study the pond-climate effect, the parallel evolution of pond numbers variation and subsequent climatic impact must be tracked. Therefore, the remote sensing-derived Normalized Difference Water Index (NDWI) was extracted from LANDSAT images with different acquisition dates to track changes in pond numbers with time. When compared with a pond map established from aerial photography interpretation, the LANDSAT NDWI map revealed an accuracy of 85.74% for pond count and 75% for pond spatial allocation.
