The purpose of this study was to evaluate factors influencing the use of propofol-based total intravenous anaesthesia (TIVA)since despite TIVA being a well-established technique, it is used far less frequently than volatile anaesthesia. Questions were formulated after reviewing the literature for perceived disadvantages of TIVA and meeting with a focus group consisting of both senior and junior anaesthestists from our department. Once the survey had been formulated, specialist anaesthetists from professional colleges and societies from several countries were invited to complete the survey on an electronic web-based platform to allow evaluation of the respondent's rating of the importance of a range of factors in their decision not to use TIVA for a particular case...

Societal risks increase as Earth warms, but also for emissions trajectories accepting relatively high levels of near-term emissions while assuming future negative emissions will compensate even if they lead to identical warming [1]. Accelerating carbon dioxide (CO2 ) emissions reductions, including as a substitute for negative emissions, hence reduces long-term risks but requires dramatic near-term societal transformations [2]. A major barrier to emissions reductions is the difficulty of reconciling immediate, localized costs with global, long-term benefits [3, 4]...

Most climate mitigation scenarios involve negative emissions, especially those that aim to limit global temperature increase to 2°C or less. However, the carbon uptake potential in land-based climate change mitigation efforts is highly uncertain. Here, we address this uncertainty by using two land-based mitigation scenarios from two land-use models (IMAGE and MAgPIE) as input to four dynamic global vegetation models (DGVMs; LPJ-GUESS, ORCHIDEE, JULES, LPJmL). Each of the four combinations of land-use models and mitigation scenarios aimed for a cumulative carbon uptake of ~130 GtC by the end of the century, achieved either via the cultivation of bioenergy crops combined with carbon capture and storage (BECCS) or avoided deforestation and afforestation (ADAFF)...

Dysregulations in serotonin neurotransmission can be a strong contributing factor in suicide and impulsive-aggressive personality traits. Victims of suicide form a heterogeneous group in terms of planning, lethality and number of used methods. In this study, we tested single nucleotide polymorphisms (SNPs) of the monoamine oxidase (MAO) A and B genes on the Slovenian population, which has one of the highest suicide rates in the world. Genotyping was performed on 77 victims of complex suicide, 406 victims of simple suicide and 289 controls...

The cell and extracellular matrix (ECM) interactions play a very important role during angiogenesis. Remodeling of the extracellular matrix along with pro-angiogenic/anti-angiogenic factors, and matrix-degrading proteases, accounts for endothelial cell growth, migration, and tube formation. However, for studying angiogenesis, only limited and expensive biomaterials are available. Despite being biocompatible, inexpensive, and easy availability; the potential of goat tendon collagen (GTC) has never been explored for vascular tissue engineering applications...

National forest inventories in tropical regions are sparse and have large uncertainty in capturing the physiographical variations of forest carbon across landscapes. Here, we produce for the first time the spatial patterns of carbon stored in forests of Democratic Republic of Congo (DRC) by using airborne LiDAR inventory of more than 432,000 ha of forests based on a designed probability sampling methodology. The LiDAR mean top canopy height measurements were trained to develop an unbiased carbon estimator by using 92 1-ha ground plots distributed across key forest types in DRC...

Importance: Digital pathology represents a transformative technology that impacts dermatologists and dermatopathologists from residency to academic and private practice. Two concerns are accuracy of interpretation from whole-slide images (WSI) and effect on workflow. Studies of considerably large series involving single-organ systems are lacking. Objective: To evaluate whether diagnosis from WSI on a digital microscope is inferior to diagnosis of glass slides from traditional microscopy (TM) in a large cohort of dermatopathology cases with attention on image resolution, specifically eosinophils in inflammatory cases and mitotic figures in melanomas, and to measure the workflow efficiency of WSI compared with TM...

BACKGROUND: Sudden unexpected death in epilepsy (SUDEP) is rare in well-controlled epilepsy. However, SUDEP is a common cause of death in drug-resistant epilepsy. Over the last 30 years, multiple cohort and population studies have identified clinical risk factors associated with an increased risk for SUDEP. OBJECTIVE: To identify and rank the leading SUDEP risk factors from major cohort and population-based studies. The incidence of SUDEP is also evaluated in special clinical situations, including antiepileptic drug treatment, epilepsy surgery, devices, and assignment to placebo in clinical trials...

Recent studies demonstrated that aberrant activation of Toll-like receptor (TLR) 4 was involved in the pathogenesis of Henoch-Schönlein purpura (HSP). In this study, we evaluated the association between TLR4 gene polymorphisms and the risk of childhood HSP in a Chinese population. A total of 175 HSP patients and 186 controls were recruited in this case-control study. Three single-nucleotide polymorphisms of the TLR4 gene (rs1927914, rs10759932 and rs1927907) were genotyped using the matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) and Sequenom MassARRAY system...
