BACKGROUND AND OBJECTIVE: EEG is a non-invasive tool for neuro-developmental disorder diagnosis and treatment. However, EEG signal is mixed with other biological signals including Ocular and Muscular artifacts making it difficult to extract the diagnostic features. Therefore, the contaminated EEG channels are often discarded by the medical practitioners which may result in less accurate diagnosis. Many existing methods require reference electrodes, which will create discomfort to the patient/children and cause hindrance to the diagnosis of the neuro-developmental disorder and Brain Computer Interface in the pervasive environment...

The prominent advantage of meshfree method, is the way to build the representation of computational domain, based on the nodal points without any explicit meshing connectivity. Therefore, meshfree method can conveniently process the numerical computation inside interested domains with large deformation or inhomogeneity. In this paper, we adopt the idea of meshfree representation into cardiac medical image analysis in order to overcome the difficulties caused by large deformation and inhomogeneous materials of the heart...

In recent years, historians have turned their attention to the emergence of anti-aging medicine, suggesting that this interest group coalesced in the wake of widespread availability of recombinant human growth hormone (HGH) after 1985. We take a longer view of modern anti-aging medicine, unearthing a nexus of scientific, medical, and cultural factors that developed over several decades in the twentieth century to produce circumstances conducive to the emergence of this medical sub-specialty established on the premise of the anti-aging effects of HGH...

Developments in organ preservation techniques, novel immunosuppressants and improved diagnostics have made organ transplantation the success it is today. That does not mean that we are not still striving to perfect techniques, or that there are no more problems to solve. New strategies to address the donor organ shortage, prevent and manage antibody-mediated rejection, lower long-term allograft failure rates and reduce the toxicity of life-long immunosuppressive medication are urgently needed, and are being widely researched...

OBJECTIVE: The field of cognitive science has provided important insights into mental processes underlying the interpretation of imaging examinations. Despite these insights, diagnostic error remains a major obstacle in the goal to improve quality in radiology. In this article, we describe several types of cognitive bias that lead to diagnostic errors in imaging and discuss approaches to mitigate cognitive biases and diagnostic error. CONCLUSION: Radiologists rely on heuristic principles to reduce complex tasks of assessing probabilities and predicting values into simpler judgmental operations...

Competency-based medical education (CBME) has been the subject of heated debate since its inception in medical education. Despite the many challenges and pitfalls of CBME that have been recognized by the medical education community, CBME is now seeing widespread implementation. However, the biggest problems with CBME still have not been solved. Two of these problems, reductionism and loss of authenticity, present major challenges when developing curricula and assessment tools.The authors address these problems by making a call for flexibility in competency definitions and for the use of mixed methods in CBME...

How to image objects that are hidden from a camera's view is a problem of fundamental importance to many fields of research, with applications in robotic vision, defence, remote sensing, medical imaging and autonomous vehicles. Non-line-of-sight (NLOS) imaging at macroscopic scales has been demonstrated by scanning a visible surface with a pulsed laser and a time-resolved detector. Whereas light detection and ranging (LIDAR) systems use such measurements to recover the shape of visible objects from direct reflections, NLOS imaging reconstructs the shape and albedo of hidden objects from multiply scattered light...

Automatic and accurate segmentation of hippocampal structures in medical images is of great importance in neuroscience studies. In multi-atlas based segmentation methods, to alleviate the misalignment when registering atlases to the target image, patch-based methods have been widely studied to improve the performance of label fusion. However, weights assigned to the fused labels are usually computed based on predefined features (e.g. image intensities), thus being not necessarily optimal. Due to the lack of discriminating features, the original feature space defined by image intensities may limit the description accuracy...

BACKGROUND: Very often patients utilize primary care services for health conditions related to social problems. These problems, which are not primarily medical, can severely influence the course of an illness and its treatment. Little is known about the extent to which problems like unemployment or loneliness occur in a general practice setting. OBJECTIVES: What are the most frequent health-related social problems perceived by general practitioners (GPs)? How are these problems associated with GP- or practice characteristics? How do general practitioners deal with the social problems they perceive and what kind of support do they need? MATERIALS AND METHODS: Cross-sectional, postal questionnaire survey with questions derived from "Chapter Z social problems" of the International Classification of Primary Care - 2nd edition...

Organ transplantation is a new issue in medical science. It is an important achievement and a sign of the progression and ability of medical centers around the world. Governments, populations, the medical community and people involved in culture, art, and media all have a decisive role in the culture of organ donation, which is the only way to guarantee that the healthy organs of a brain-dead person can continue to work and save the lives of people in need of organ transplantation. The brain death phenomenon and its possible application in organ transplantation, while offering new hope for the salvation of a number of patients, has led to many ethical, cultural, and legal issues...
