Alsharif Abuadbba, Ibrahim Khalil
Remote points-of-care has recently had a lot of attention for their advantages such as saving lives and cost reduction. The transmitted streams usually contain (1) normal biomedical signals (e.g. ECG) and (2) highly private information (e.g. patient identity). Despite the obvious advantages, the primary concerns are privacy and authenticity of the transferred data. Therefore, this paper introduces a novel steganographic mechanism that ensures (1) strong privacy preservation of private information by random concealing inside the transferred signals employing a key, and (2) evidence of originality for the biomedical signals...

Amanda Grenier, Rachel Barken, Colleen McGrath
The concepts of 'house' and 'home' are compelling and contradictory. They are compelling because they elicit the desired sentiments of permanence, feeling 'at home', and maintaining continuity in one's life. At the same time, they can be experienced as contradictory where organizational practices and the socio-cultural imperatives of individual responsibility, cost containment, and rationed services are concerned. Where 'house' tends to evoke a sense of permanent stability, 'home' is regarded as the ideal living environment and site of care for older people...

Photoacoustic tomography has emerged as a promising non-invasive imaging technique that integrates the merits of high optical contrast with high ultrasound resolution in deep scattering medium. Unfortunately, the blood background in vivo seriously impedes the quality of imaging due to its comparable optical absorption with contrast agents, especially in conventional linear photoacoustic imaging modality. In this study, we demonstrated that two hybrids consisting of gold nanorods (Au NRs) and zinc tetra(4-pyridyl)porphyrin (ZnTPP) exhibited a synergetic effect in improving optical absorption, conversion efficiency from light to heat, and thermoelastic expansion, leading to a notable enhancement in both linear (four times greater) and nonlinear (more than six times) photoacoustic signals as compared with conventional Au NRs...

BACKGROUND: Prospect theory suggests that when faced with an uncertain outcome, people display loss aversion by preferring to risk a greater loss rather than incurring certain, lesser cost. Providing probability information improves decision making towards the economically optimal choice in these situations. Clinicians frequently make decisions when the outcome is uncertain, and loss aversion may influence choices. This study explores the extent to which prospect theory, loss aversion, and probability information in a non-clinical domain explains clinical decision making under uncertainty...

Our experience in cardio-thoracic surgery focuses on thoracic activity. The minimum fare for traumatisms, infectious pathology and tumoral pathology requires, for its improvement, the acquisition of a technical platform and of an adequate medical infrastructure, with a rational organisation of the care sequence. Vascular surgery calls for the training of qualified human resources, and the great demand in heart surgery calls upon the public powers for the construction of infrastructures, and the formation of necessary superstructures...

BACKGROUND: The 'inherited' patient, where a patient switches to a new doctor, is a common and potentially challenging scenario, especially where drugs of dependence are involved. There are few resources to guide general practitioners (GPs) with an approach that ensures compassion and rational clinical decision-making. OBJECTIVE: The aim of this article is to guide GPs in an approach to taking over the care of an inherited patient and focuses on considerations of rational prescribing...

Quality control requirements imposed on assays used in clinical diagnostics and point-of-care-diagnostic testing (POCT), utilizing amplification reactions performed at elevated temperatures of 35 to 95 °C are very stringent. As the temperature of a reaction vessel has a large impact on the specificity and sensitivity of the amplification reaction, simple tools for local in situ temperature sensing and monitoring are required for reaction and assay control. We describe here a platform of stem-and-loop structured DNA hairpins (molecular beacons, MBs), absorbing and emitting in the visible and red spectral region, rationally designed for precise temperature measurements in microfluidic assays for POCT, and their application for temperature measurements in a common DNA-based molecular biological assay utilizing thermophilic helicase-dependent amplification (tHDA)...

Deep desulfurization is a challenging task and global efforts are focused on the development of new approaches for the reduction of sulfur-containing compounds in fuel oils. In this work, we have proposed a new design strategy for the development of deep desulfurization heterogeneous catalysts. Based on the adopted design strategy, a novel composite material of polyoxometalate (POM)-based ionic liquid-grafted layered double hydroxides (LDHs) was synthesized by an exfoliation/grafting/assembly process. The structural properties of the as-prepared catalyst were characterized using FT-IR, XRD, TG, NMR, XPS, BET, SEM and HRTEM...

INTRODUCTION: General practitioners (GP) in Spain do not have access to rapid tests and adherence to guidelines is usually suboptimal. The aim of the study is to evaluate the estimated number of antibiotics that could have been saved if GPs had appropriately used these tests and had followed the guidelines. DESIGN: Observational study. SETTING: Primary care centres from eight Autonomous Communities in Spain. PARTICIPANTS: GPs who had not participated in previous studies on rational use of antibiotics...

We study implications of a change in the payment scheme for radiology providers in Norway that was implemented in 2008. The change implies reduced fee-for-service and increased fixed budget for a contracted volume of services. A consequence of the change is that private providers have less incentive to conduct examinations beyond the contracted volume. Different from the situation observed before the change in 2008, the volume is no longer determined by the demand side, and a rationing of the supply occurs...

In the traditional biomedical model of clinical practice, which assumes a medicine focused on disease, diseases are considered as biological or psycho-physiological universal entities. This explanation, although necessary, is not enough. Several authors have recently become interested in the use of narrative practices in the medical care setting, underlining the increasing importance of "a patient-centered approach", a "relationship -centered care" and "narrative medicine". Even in Nursing, the challenge was to combine two models that seemed incompatible: the Evidence-Based Nursing Model and the Narrative-Based Nursing Model...

INTRODUCTION: Evidence Based Prevention is becoming increasingly important to guide the policy-makers to choose preventive interventions to be offered to the population. Sometimes however the impact of an intervention in real conditions (effectiveness) may be smaller than the efficacy estimated in studies conducted in experimental settings. This can be due for example to suboptimal coverage of the intervention or to poor compliance of the involved subjects. Regrettably, this aspect is rarely taken into account in the planning of preventive interventions...

Central vein cannulation is one of the most commonly performed procedures in intensive care. Traditionally, the jugular and subclavian vein are recommended as the first choice option. Nevertheless, these attempts are not always obtainable for critically ill patients. For this reason, the axillary vein seems to be a rational alternative approach. In this narrative review, we evaluate the usefulness of the infraclavicular access to the axillary vein. The existing evidence suggests that infraclavicular approach to the axillary vein is a reliable method of central vein catheterization, especially when performed with ultrasound guidance...

BACKGROUND: Health professionals must often balance between different rationalities within the hospital organisation. Having adequate time with patients, shorter waiting time and the ability to greater professional autonomy have been shown to help provide a higher quality of care. Empathy and sympathy appear to be crucial components for the health professionals and their relationship to patients. AIM: The aim of this study was to explore health professionals' experiences of relatives to critically ill patients in order to identify aspects that may facilitate a better understanding of this teamwork...

PURPOSE OF REVIEW: As in adults and older children, anemia in newborn infants can be the result of erythropoietic failure, hemorrhage, or hemolysis. When hemolysis is the prime consideration, it can be challenging for physicians caring for neonates to choose from the wide variety of available diagnostic tests. This review describes the authors' opinions regarding rational, consistent, and cost-effective means of making an exact diagnosis of a neonatal hemolytic condition. RECENT FINDINGS: Two recent advances in the diagnosis of neonatal nonimmune hemolytic disorders are highlighted in this review: introduction of flow cytometry-based Eosin-5-maleimide (EMA) uptake as a screening test to identify RBC membrane defects and next-generation sequencing (NGS)-based panels to uncover exact mutations causing hemolysis...

This study aimed to determine whether the label status of a medicine penetrates into the clinical reasoning of Australian medical practitioners and to explore the possible reasons for our findings using semistructured interviews with 14 Australian physicians. The interviews revealed 3 broad catalysts for off-label prescribing. The first of these was lack of awareness or understanding of the regulatory process in general and labels more specifically. The second was the perception that labels are not meaningful guides for clinical practice...

Pruritus (itch) is the most frequent skin symptom. It can be attributed to a skin disease in many cases. Furthermore pruritus may also be a precursing symptom or principal complaint of an internal, neurological or psychiatric disease. It has been observed that elderly patients are increasingly affected. In many cases pruritus has multifactorial causes. This requires careful diagnostics, including a detailed medical history and medical examination of the patient. Previous diseases and comorbidities need to be considered as possible causes, as well as current and previous drug intake...
