BACKGROUND: Many chronic fatigue syndrome (CFS) and fibromyalgia syndrome (FMS) patients (35-68%) use nutritional supplements, while it is unclear whether deficiencies in vitamins and minerals contribute to symptoms in these patients. Objectives were (1) to determine vitamin and mineral status in CFS and FMS patients as compared to healthy controls; (2) to investigate the association between vitamin and mineral status and clinical parameters, including symptom severity and quality of life; and (3) to determine the effect of supplementation on clinical parameters...

BACKGROUND: Quantitative sonographic methods are used to assess pleural fluid's volume but no validated method exists for the measurement of the fluids' density and other qualitative values. We suggest a quantitative method, based on the pixel density of the pleural effusion's image, in order to evaluate the echogenicity of pleural effusion. METHODS: Pleural ultrasound (US) was performed in 62 patients with pleural effusion. Five consequent images of the pleural effusion were retrieved through axial view between the 9(th) and the 10(th) rib and one from the 10(th) rib through coronal view and converted into the high-resolution tagged image file format...

Calmodulin (CaM) functions depend on interactions with CaM-binding proteins, regulated by Ca2+. Induced structural changes influence the affinity, kinetics, and specificities of the interactions. The dynamics of CaM interactions with neurogranin (Ng) and the CaM-binding region of Ca2+/calmodulin-dependent kinase II (CaMKII290-309 ) have been studied using biophysical methods. These proteins have opposite Ca2+ dependencies for CaM binding. Surface plasmon resonance biosensor analysis confirmed that Ca2+ and CaM interact very rapidly, and with moderate affinity ( KDSPR=3μM)...

BACKGROUND: Making diagnostic and therapeutic decisions is a critical activity among physicians. It relies on the ability of physicians to use cognitive processes and specific knowledge in the context of a clinical reasoning. This ability is a core competency in physicians, especially in the field of emergency medicine where the rate of diagnostic errors is high. Studies that explore medical decision-making in an authentic setting are increasing significantly. They are based on the use of qualitative methods which are applied at two separate times: 1) a video recording of the subject's actual activity in an authentic setting and 2) an interview with the subject, supported by the video recording...

Species within the genus Centaurium readily hybridize and polyploid complexes are often seen in natural populations. We describe phytochemical profiles of newly discovered allohexaploid hybrid, here named Centaurium pannonicum, and its parental tetraploid species C. erythraea and rare C. littorale ssp. compressum. Our aim was to examine chemodiversity of these taxa in the area of Vojvodina (North Serbia) and to perform metabolomics search for chemical classifiers which would provide high resolution discrimination of parental and hybrid individuals...

Complementary and alternative medicine (CAM) is widely used among the breast cancer patients in Malaysia. Delays in presentation, diagnosis and treatment have been shown to impact the disease prognosis. There is considerable use of CAM amongst breast cancer patients. CAM use has been cited as a cause of delay in diagnosis and treatments in qualitative studies, however there had not been any confirmatory study that confirms its impact on delays. The purpose of this study was to evaluate whether the use of CAM among newly diagnosed breast cancer patients was associated with delays in presentation, diagnosis or treatment of breast cancer...

BACKGROUND: The Edmonton Symptom Assessment System-revised (ESAS-r) is a nine-item self-report symptom intensity tool developed for palliative care patients, with the option of adding a 10th patient-specific symptom. Due to growing international uptake, the ESAS-r has been translated into different languages. There has not been agreement, however, regarding a standard process for translation into multiple languages, which also includes patients' perspectives. OBJECTIVE: The purpose of this study was to develop a French version of the ESAS-r, using a standardized translation protocol, and to obtain palliative care patients' perspectives regarding this translated tool...

Density Functional Theory(DFT) is widely applied in chemistry and Physics. Still it fails to predict correctly quantitatively or even qualitatively for systems with significant nondynamic correlations. Several DFT functionals were proposed in recently years to treat nondynamic correlation, most of which added the exact exchange energy density as a new variable, which becomes the computational bottleneck for calculations with these new functionals We present an implementation of an efficient seminumerical algorithm in this paper as a solution for this computational bottleneck...

Interest in the study of brain connectivity is growing, particularly in understanding the dynamics of the structural/functional connectivity relation. Structural and functional connectivity are most often analysed independently of each other. Track-weighted functional connectivity (TW-FC) was recently proposed as a means to combine structural/functional connectivity information into a single image. We extend here TW-FC in two important ways: first, all the functional data are used without having to define a prior functional network (cf...

INTRODUCTION: In North America, drug overdose deaths are reaching unprecedented levels, largely driven by increasing prescription opioid-related deaths. Despite the development of several opioid guidelines, prescribing behaviours still contribute to poor patient outcomes and societal harm. Factors at the provider and system level may hinder or facilitate the application of evidence-based guidelines; interventions designed to address such factors are needed. METHODS AND ANALYSIS: Using implementation science and behaviour change theory, we have planned the development and evaluation of a comprehensive Opioid Self-Assessment Package, designed to increase adherence to the Canadian Opioid Guideline among family physicians...

BACKGROUND: Consent remains a crucial, yet challenging, cornerstone of clinical practice. The ethical, legal and professional understandings of this construct have evolved away from a doctor-centred act to a patient-centred process that encompasses the patient's values, beliefs and goals. This alignment of consent with the philosophy of shared decision-making was affirmed in a recent high-profile Supreme Court ruling in England. The communication of information is central to this model of health care delivery but it can be difficult for doctors to gauge the information needs of the individual patient...

Aim The aim of this qualitative study was to explore band 5 nurses' perceptions and experiences of professional development in an acute care provider to identify what, if any, effect these have on their job satisfaction and intention to stay in post. Method An adapted grounded theory approach was used. Theoretical sampling identified band 5 nurses in their first 24 months of employment in the trust. Data were collected through focus groups and analysed using the constant comparative method. Results Findings suggest that the provision of, and support for, development opportunities affect nurses' job satisfaction, and investment in these opportunities is likely to improve staff retention...

Immunocapture-based bottom-up LC-MS is a promising technique for the quantification of low abundant proteins. Magnetic immunocapture beads provide efficient enrichment from complex samples through the highly specific interaction between the target protein and its antibody. In this article, we have performed the first thorough comparison between digestion of proteins while bound to antibody coated beads versus after elution from the beads. Two previously validated immunocapture based MS methods for the quantification of pro-gastrin releasing peptide (ProGRP) and human chorionic gonadotropin (hCG) were used as model systems...

AIMS AND OBJECTIVES: This paper describes undergraduate student nurse responses to a simulated role-play experience focussing on managing interruptions during medication administration. BACKGROUND: Improving patient safety requires that we find creative and innovative methods of teaching medication administration to undergraduate nurses in real-world conditions. Nurses are responsible for the majority of medication administrations in health care. Incidents and errors associated with medications are a significant patient safety issue and often occur as a result of interruptions...
