Late Campylobacter jejuni mastitis after augmentation mammoplasty
Breast implant-associated infections (BIAI) occur in approximately 2% of patients after augmentation mammoplasty. In some cases, BIAI can be treated conservatively, whereas others need implant removal. Knowledge of uncommon potential pathogens in BIAI is important to ensure optimal treatment of BIAI. In the present case report, we describe a case of bilateral late Campylobacter jejuni mastitis in
On heat transfer and flow characteristics of jets impingement on a concave surface with varying pin-fin arrangements
Numerical simulations have been conducted to investigate the effects of pin-fin arrangement and jet Reynolds number on heat transfer enhancement and flow characteristics of a concave confined jet impingement cooled surface conjugated with pin-fins. The results without a pin-fin are used as a baseline. Vortices and different sections of streamlines in the channel are employed to understand the flow
Antileukotrienes for the prevention and treatment of chronic lung disease in very preterm newborns : a systematic review
Background: Very preterm infants are at high risk of developing chronic lung disease, which requires respiratory support and might have long-term sequelae. As lung inflammation plays an important role in pathogenesis, antileukotrienes have been explored in both clinical and animal studies. We aimed to assess the benefits and harms of antileukotrienes for the prevention and treatment of respiratory
Combustion sensitivity to the nozzle hole size in an active pre-chamber ultra-lean heavy-duty natural gas engine
Active pre-chamber configurations are considered a valuable solution for improving the operation of the internal combustion engine, in the view to overcome the many challenges it has been made to face. Combining this technology with the use of natural gas, a fuel that has increasing availability and interest in the market share, it is possible to burn ultra-lean mixtures (with air-to-fuel ratios,
Efficient and timely downstream passage solutions for European silver eels at hydropower dams
The European eel population is critically endangered due to a multitude of human-induced factors such as habitat fragmentation, parasites, fishing, and climate change. In freshwater, downstream migrating silver eels encountering hydroelectric plants often suffer substantial delays and increased mortality from trash-rack impingement and turbine-induced mortality. Downstream passage problems can be
A spatiotemporal ensemble model to predict gross beta particulate radioactivity across the contiguous United States
Particulate radioactivity, a characteristic of particulate matter, is primarily determined by the abundance of radionuclides that are bound to airborne particulates. Exposure to high levels of particulate radioactivity has been associated with negative health outcomes. However, there are currently no spatially and temporally resolved particulate radioactivity data for exposure assessment purposes.
Nasopharyngeal cultures in children with AOM – A retrospective study on bacteriological findings and impact on management
Background: Despite a far from perfect correlation with middle ear growth, nasopharyngeal cultures are sometimes used in children with acute otitis media (AOM) in order to have some idea of the causative pathogen. How these cultures are used in clinical practice and to what extent they influence clinical management has not previously been studied. The objective with this study was to investigate i
Numerical modelling of wood under combined loading of compression perpendicular to the grain and rolling shear
Numerical modeling is an efficient tool for experimental validation and for gaining a deeper understanding of complex material phenomena, especially when causal relationships are overlaid by material variability. Wood is such a highly orthotropic and complex material, which in engineering problems however is considered as macro-homogeneous. The aim of this study is to numerically investigate stres
Direct Cannula Implantation in the Cisterna Magna of Pigs
The glymphatic system is a waste clearance system in the brain that relies on the flow of cerebrospinal fluid (CSF) in astrocyte-bound perivascular spaces and has been implicated in the clearance of neurotoxic peptides such as amyloid-beta. Impaired glymphatic function exacerbates disease pathology in animal models of neurodegenerative diseases, such as Alzheimer's, which highlights the importance
Demonstration and pantomime in the evolution of teaching and communication
The article begins with a presentation of the role of demonstration and pantomime in the evolution of teaching building on Gärdenfors and Högberg (2017). In comparison to different forms of animal communication, demonstration is voluntary, intentional, honest, and directed to one or a few individuals. Then the differences between demonstration and pantomime is analyzed. An important factor is that
Bayesian Network Applications for Sustainable Holistic Water Resources Management : Modeling Opportunities for South Africa
Anthropogenic transformation of land globally is threatening water resources in terms of quality and availability. Managing water resources to ensure sustainable utilization is important for a semiarid country such as South Africa. Bayesian networks (BNs) are probabilistic graphical models that have been applied globally to a range of water resources management studies; however, there has been ver
Correlates of intended COVID-19 vaccine acceptance across time and countries : Results from a series of cross-sectional surveys
Objective Describe demographical, social and psychological correlates of willingness to receive a COVID-19 vaccine. Setting Series of online surveys undertaken between March and October 2020. Participants A total of 25 separate national samples (matched to country population by age and sex) in 12 different countries were recruited through online panel providers (n=25 334). Primary outcome measures
A Systematic review of individual Placement and Support, Employment, and Personal and Clinical recovery
Objective:The objective of this review was to assess associations between Individual Placement and Support (IPS), employment, and personal and clinical recovery among persons with severe mental illness at 18-month follow-up.Methods:A systematic literature search identified randomized controlled trials (RCTs) comparing IPS with services as usual. Outcomes were self-esteem, empowerment, quality of l
Differential regulation of oxidative stress, microbiota-derived, and energy metabolites in the mouse brain during sleep
Sleep has evolved as a universal core function to allow for restorative biological processes. Detailed knowledge of metabolic changes necessary for the sleep state in the brain is missing. Herein, we have performed an in-depth metabolic analysis of four mouse brain regions and uncovered region-specific circadian variations. Metabolites linked to oxidative stress were altered during sleep including
Changes in rehabilitation actors´mental health literacy and support to employers: An evaluation of the SEAM intervention
BACKGROUND:Lack of mental health literacy among rehabilitation professionals and employers in the return-to-work of persons with mental health problems resulted in the development of a three-day group training program, the Support to Employers from rehabilitation Actors about Mental health (SEAM) intervention.OBJECTIVE:To evaluate the impact of SEAM on rehabilitation professionals’ knowledge and b
Hot topics in agricultural and environmental economics – a large-scale bibliometric analysis
Land use is at the core of today’s complex sustainability challenges. Agricultural and environmental economics share a focus land and resource use but evolved in their own domains. Their specialized competencies can be complementary and thus strengthen policy analysis. We use structural topic modelling on more than 24,000 articles in the top agricultural economics and environmental economics journ
Host-parasites transfert of micropollutants and eco-physiological consequences on a freshwater fish: Case study of chub-acanthocephalan model
Exposure to complex mixtures of environmental contaminants may have severe consequences in free-living animals through the disruption of physiological mechanisms, reduced reproductive outputs and survival, thereby leading to population collapse. Contaminant analyses in fish have been used as a routine approach in studies of aquatic pollution. Located at the upper levels of the food webs, fish are
Changing land cover as a driver of surface water browning
Streams, rivers and lakes across wide areas of the Northern hemisphere have been subject to an increase in water color over the last decades. This increase, also known as browning, is a result of rising dissolved organic matter (DOM) and iron (Fe) concentrations in the water. Over the years, browning has received ample attention due to its impact on the structure and function of freshwater ecosyst
