A 76-year-old man with a history of frequent syncope in youth and in the last 5 years was referred for a head-up tilt test. During the head-up tilt test, he developed a classical vasovagal reflex syncope. On immediate return to the supine position, the patient regained consciousness. Shortly afterward, the heart rate slowed distinctly and the patient became unresponsive with undetectable blood pre
Assessment of respiratory tract deposition of nanoparticles is a key link to understanding their health impacts. An instrument was developed to measure respiratory tract deposition of nanoparticles in a single breath. Monodisperse nanoparticles are generated, inhaled and sampled from a determined volumetric lung depth after a controlled residence time in the lung. The instrument was characterized
Background: Hemodynamic instability responsive to fluid resuscitation is common after a traumatic brain injury (TBI), also in the absence of systemic hemorrhage. The present study tests if an isolated severe TBI induces a decrease in plasma volume (PV). Methods: The study was performed in three groups of anesthetized and tracheostomized male cats (n = 21). In one group (n = 8), the cats were prepa
Summary: Osteoporotic fractures may pose a challenge for skeletal regeneration. This study investigates if pharmaceutical interventions such as bone morphogenetic protein 7 (BMP-7) alone or in combination with Zoledronate have equivalent efficacy in osteoporotic bone? Our findings suggest they do and that an osteoporotic bone environment may increase sensitivity to BMP-7. Introduction: Osteoporosi
Axonal white matter injury is believed to be a major determinant of adverse outcomes following traumatic brain injury (TBI). We hypothesized that measurement of neurofilament light protein (NF-L), a protein found in long white-matter axons, in blood samples, may serve as a suitable biomarker for neuronal damage in TBI patients. To test our hypotheses, we designed a study in two parts: i) we develo
Background: There are several indications that the composition of the tumor stroma can contribute to the malignancy of a tumor. Here we utilized expression data sets to identify metagenes that may serve as surrogate marker for the extent of matrix production and vascularization of a tumor and to characterize prognostic molecular components of the stroma. Methods: TCGA data sets from six cancer for
The evolution and maintenance of conspicuous phenotypic polymorphisms has challenged evolutionary ecologists for centuries. Polymorphisms in pleiotropic cascades or genetic linkage may lead to correlations of life history traits such as immunity, parasite infection levels, pigmentation and lifetime reproductive success. The common buzzard Buteo buteo is a bird of prey occurring in several plumage
The interaction of the ionic liquid [C4C1Im][BF4] with anatase TiO2, a model photoanode material, has been studied using a combination of synchrotron radiation photoelectron spectroscopy and near-edge X-ray absorption fine structure spectroscopy. The system is of interest as a model for fundamental electrolyte–electrode and dye-sensitized solar cells. The initial interaction involves degradation o
Purpose: The aim of this study was to describe experiences of attitudes in the society of Sierra Leone from the perspective of individuals with poliomyelitis and people with amputations using orthotic or prosthetic devices. Methods: Individual interviews were conducted using open-ended questions. Twelve participants with amputations or polio were included. Content analysis was applied to the data.
This study investigates how, and to what extent, citizens use Twitter as a platform for political mobilization in an electoral context. Conceptualizing political participation as a process, we develop a typology of political participation designed to isolate mobilizing calls for action from the rest of the political discussion online. Based on Twitter data collected one week prior to the 2015 Brit
Purpose: The aims of this study were to assess the short- and long-term complication rates after video-assisted gastrostomy (VAG), the effects of age and gender on long-term complications and the effect of duration of gastrostomy tube retention on the need for gastroraphy when the gastrostomy device was removed. Methods: This was a retrospective study of children undergoing VAG at a single institu
The role of the skin microbiota in human health is poorly understood. Here, we identified and characterized a novel antioxidant enzyme produced by the skin microbiota, designated RoxP for radical oxygenase of Propionibacterium acnes. RoxP is uniquely produced by the predominant skin bacterium P. acnes, with no homologs in other bacteria; it is highly expressed and strongly secreted into culture su
Introduction: Identifying factors that influence individuals' smoking behavior remains a huge public health concern. This study aimed to investigate changes in individuals' cigarette smoking while considering well-known smoking determinants, including social capital, its presence being postulated to reduce smoking. Methods: From British Household Panel Survey data, two baseline smoking cohorts wer
Background Response to disease modifying antirheumatic drugs (DMARDs) in rheumatoid arthritis (RA) is often heterogeneous. We aimed to identify types of disease activity trajectories following the initiation of a new biologic DMARD (bDMARD). Methods Pooled analysis of nine national registries of patients with diagnosis of RA, who initiated Abatacept and had at least two measures of disease activit
IntroductionInterprofessional teamwork is associated with improved patient safety and job satisfaction. Previous research indicates that issues often appear when different professions’ perspectives don’t match up and it also shows that the use of the concept of teamwork within the healthcare literature is not as clear as could be expected. Therefore it is of interest to study how healthcare profes
IntroductionGovernment and public agencies in Sweden have promoted the expansion of eHealth. The strategy behind many of the eHealth services is to increase quality of care, enhance efficiency, patient empowerment and patient safety. Patient online access to their electronic health record (EHR) is one of the most important civic eHealth services. By 2017, all patients in Sweden will be able to acc
Recently a lot has been written on the topic of value incomparability. While there is disagreement on how we are to understand incomparability, most seem to accept Ruth Chang's claim that all comparisons must proceed in some specific respect. Call this the Requirement for Specification. Interestingly, even though most seem to accept this requirement, next to nothing has been written on it. In this
