#1
Xue Dong, Jianying Bai, Min Bao
A new illusion is described. Randomly positioned dots moved radially within an imaginary annular window. The dots' motion periodically changed the direction, leading to an alternating percept of expanding and contracting motion. Strikingly, the apparent size of the enclosed circular region shrank during the dots' expanding phases and dilated during the contracting phases. We quantitatively measured the illusion, and found that the presence of energy at the local kinetic edge could not account for the illusion...

BACKGROUND: In addition to medical intervention and counseling, patients with cardiovascular disease (CVD) need to manage their disease and its consequences by themselves in daily life. OBJECTIVE: The aim of this paper is to describe the development of "Vascular View," a comprehensive, multi-component, tailored, Web-based, self-management support program for patients with CVD, and how this program will be tested in an early randomized controlled trial (RCT). METHODS: The Vascular View program was systematically developed in collaboration with an expert group of 6 patients, and separately with a group of 6 health professionals (medical, nursing, and allied health care professionals), according to the following steps of the intervention mapping (IM) framework: (1) conducting a needs assessment; (2) creating matrices of change objectives; (3) selecting theory-based intervention methods and practical applications; (4) organizing methods and applications into an intervention program; (5) planning the adaption, implementation, and sustainability of the program, and (6) generating an evaluation plan...

Approaches to ageing that are organised around productivity, success, and active late life have contributed to views of dementia as an unsuccessful, failed or 'frailed' old age. Operating through dominant frameworks, socio-cultural constructs and organisational practices, the 'frailties' of the body and mind are often used to mark the boundaries of health and illness in late life, and shape responses accordingly. Our concern is that both the taken for granted and the 'imagined' can further marginalise persons who occupy the locations of dementia and disablement...

OBJECTIVE: Glioma survival correlated with the extent of resection and the functional status of the patient. We detailed functional results along with oncological results after a functional-based resection of gliomas located within eloquent regions. MATERIAL AND METHODS: Single centre prospective series of adult patients with gliomas located within eloquent regions, treated with maximal resection according to functional boundaries using intraoperative cortico-subcortical monitoring under awake conditions, with available functional outcomes (language and cognitive assessments, neurological status, ability to work) and oncological outcomes (extent of surgical resection, survivals)...

The exploration of frailty as a pre-disability geriatric condition represents one of the most promising research arenas of modern medicine. Frailty is today indicated as a paradigmatic condition around which the traditional healthcare systems might be re-shaped and optimized in order to address the complexities and peculiarities of elders. Unfortunately, the lack of consensus around a single operational definition has limited the clinical implementation of frailty in clinical practice. In these last years, growing attention (even beyond the traditional boundaries of geriatric medicine) has been given to physical performance measures...

Caring nurse-patient relationships in mental health settings are key components in helping patients recover. These professional relationships provide a safe, trustworthy, reliable, and secure foundation for therapeutic interactions; however, nurses face challenges in setting and maintaining relationship boundaries. Although patients ask for special privileges, romantic interactions, and social media befriending, or offer expensive gifts, nurses must recognize that these boundary violations may erode trust and harm patients...

Social networking has become an extremely popular online activity, however like many activities on the internet, there are some privacy risks and concerns associated with its use. In recent years an increasing number of nurses have been censured or asked to appear before regulatory or registering authorities for unprofessional behaviour on social media sites. Problem behaviours identified include: inappropriate content and postings, crossing professional boundaries and breaching patient privacy and confidentiality...

Intermarriage plays a key role in stratification systems. Spousal resemblance reinforces social boundaries within and across generations, and the rules of intermarriage govern the ways that social mobility may occur. We examine intermarriage across social origin and education boundaries in the United States using data from the 1968-2013 Panel Study of Income Dynamics. Our evidence points to a pattern of status exchange-that is, persons with high education from modest backgrounds tend to marry those with lower education from more privileged backgrounds...

PURPOSE: To compute daily dose delivered during radiotherapy, deformable registration needs to be relatively fast, automated, and accurate. The aim of this study was to evaluate the performance of commercial deformable registration software for deforming between two modalities: planning computed tomography (pCT) images acquired for treatment planning and cone beam (CB) CT images acquired prior to each fraction of prostate cancer radiotherapy. METHODS: A workflow was designed using MIM Softwareâ„¢ that aligned and deformed pCT into daily CBCT images in two steps: (1) rigid shifts applied after daily CBCT imaging to align patient anatomy to the pCT and (2) normalized intensity-based deformable registration to account for interfractional anatomical variations...

PURPOSE: In this study, we developed and evaluated a method for predicting lung surface deformation vector fields (SDVFs) based on surrogate signals such as chest and abdomen motion at selected locations and spirometry measurements. METHODS: A Patient-specific 3D triangular surface mesh of the lung region at end-expiration (EE) phase was obtained by threshold-based segmentation method. For each patient, a spirometer recorded the flow volume changes of the lungs; and 192 selected points at a regular spacing of 2cm X 2cm matrix points over a total area of 34cm X 24cm on the surface of chest and abdomen was used to detect chest wall motions...

REVIEW
Thomas Efferth, Mita Banerjee, Norbert W Paul
The cardiac impact of psychological stress historically and socially understood as boundary experiences of human life has long since become an icon. From the aching heart to the sudden death provoked by awe, horror, grief, anger, and humiliation on one side and extreme enchantment, enthusiasm, and excitement on the other, the broken heart has become a globally recognized and powerful metaphor present from folklore to popular culture to high literature and back to everyday communication. In medicine, the "broken heart syndrome" is described as a relatively new nosological entity that has been used synonymously with the term tako-tsubo or stress cardiomyopathy...

The current healthcare system is hampered by a reductionist approach in which diagnostics and interventions focus on a specific target, resulting in medicines that center on generic, static phenomena while excluding inherent dynamic nature of biological processes, let alone psychosocial parameters. In this essay, we present some limitations of the current healthcare system and introduce the novel and potential approach of combining ultra-weak photon emission (UPE) with metabolomics technology in order to provide a dynamic readout of higher organizational systems...
