High-Resolution Electron Microscopy of Semiconductor Heterostructures and Nanostructures

This chapter briefly describes the fundamentals of high-resolution electron microscopy techniques. In particular, the Peak Pairs approach for strain mapping with atomic column resolution, and a quantitative procedure to extract atomic column compositional information from Z-contrast high-resolution images are presented. It also reviews the structural, compositional, and strain results obtained by conventional and advanced transmission electron microscopy methods on a number of III–V semiconductor nanostructures and heterostructures

Compassion: a scoping review of the healthcare literature

BACKGROUND: Recent concerns about suboptimal patient care and a lack of compassion have prompted policymakers to question the preparedness of clinicians for the challenging environment in which they practice. Compassionate care is expected by patients and is a professional obligation of clinicians; however, little is known about the state of research on clinical compassion. The purpose of this scoping review was to map the literature on compassion in clinical healthcare. METHODS: Searches of eight electronic databases and the grey literature were conducted to identify empirical studies published over the last 25 years. Eligible studies explored perceptions or interventions of compassionate care in clinical populations, healthcare professionals, and healthcare students. Following the title and abstract review, two reviewers independently screened full-texts articles, and extracted study data. A narrative approach to synthesizing and mapping the literature was used. RESULTS AND DISCUSSION: Of 36,637 records, 648 studies were retrieved and 44 studies were included in the review. Less than one third of studies included patients. Six themes emerged from studies that explored perceptions of compassionate care: nature of compassion, development of compassion, interpersonal factors related to compassion, action and practical compassion, barriers and enablers of compassion, and outcomes of compassion. Intervention studies included two compassionate care trials with patients and eight educational programs that aimed to improve compassionate care in clinicians and students. CONCLUSIONS: This review identifies the limited empirical understanding of compassion in healthcare, highlighting the lack of patient and family voices in compassion research. A deeper understanding of the key behaviors and attitudes that lead to improved patient-reported outcomes through compassionate care is necessary

How does it really feel to be in my shoes?: patients' experiences of compassion within nursing care and their perceptions of developing compassionate nurses

Aims and objectives To understand how patients experience compassion within nursing care and explore their perceptions of developing compassionate nurses. Background Compassion is a fundamental part of nursing care. Individually, nurses have a duty of care to show compassion; an absence can lead to patients feeling devalued and lacking in emotional support. Despite recent media attention, primary research around patients' experiences and perceptions of compassion in practice and its development in nursing care remains in short supply. Design A qualitative exploratory descriptive approach. Methods In-depth, semi-structured interviews were conducted with a purposive sample of 10 patients in a large teaching hospital in the United Kingdom. Interviews were digitally recorded and transcribed verbatim. Thematic networks were used in analysis. Results Three overarching themes emerged from the data: (1) what is compassion: knowing me and giving me your time, (2) understanding the impact of compassion: how it feels in my shoes and (3) being more compassionate: communication and the essence of nursing. Conclusion Compassion from nursing staff is broadly aligned with actions of care, which can often take time. However, for some, this element of time needs only be fleeting to establish a compassionate connection. Despite recent calls for the increased focus compassion at all levels in nurse education and training, patient opinion was divided on whether it can be taught or remains a moral virtue. Gaining understanding of the impact of uncompassionate actions presents an opportunity to change both individual and cultural behaviours. Relevance to clinical practice It comes as a timely reminder that the smallest of nursing actions can convey compassion. Introducing vignettes of real-life situations from the lens of the patient to engage practitioners in collaborative learning in the context of compassionate nursing could offer opportunities for valuable and legitimate professional development

Personality traits predict brain activation and connectivity when witnessing a violent conflict

As observers we excel in decoding the emotional signals telling us that a social interaction is turning violent. The neural substrate and its modulation by personality traits remain ill understood. We performed an fMRI experiment in which participants watched videos displaying a violent conflict between two people. Observers' attention was directed to either the aggressor or the victim. Focusing on the aggressor (vs. focusing on the victim) activated the superior temporal sulcus (STS), extra-striate body area (EBA), occipital poles and centro-medial amygdala (CMA). Stronger instantaneous connectivity occurred between these and the EBA, insula, and the red nucleus. When focusing on the victim, basolateral amygdala (BLA) activation was related to trait empathy and showed increased connectivity with the insula and red nucleus. STS activation was associated with trait aggression and increased connectivity with the hypothalamus. The findings reveal that focusing on the aggressor of a violent conflict triggers more activation in categorical (EBA) and emotion (CMA, STS) areas. This is associated with increased instantaneous connectivity among emotion areas (CMA-insula) and between categorical and emotion (EBA-STS) areas. When the focus is on the victim, personality traits (aggression/empathy) modulate activity in emotion areas (respectively STS and postcentral gyrus/ BLA), along with connectivity in the emotional diencephalon (hypothalamus) and early visual areas (occipital pole)

Spontaneous Resolution Of Syringomyelia Without Chiari Malformation - Case Report

A 30-year-old woman presented with a cervical syrinx manifesting as hemihypesthesia. Neuroimaging found no evidence of Chiari malformation or tight cisterna magna. Serial magnetic resonance imaging studies over a 6-year period demonstrated spontaneous and complete resolution of the syrinx accompanied by an asymptomatic clinical course. The natural history of syringomyelia is highly unpredictable. The outcome of surgical treatment for patients with syringomyelia is not always satisfactory, so the indications for surgery are controversial. Spontaneous resolution of syringomyelia unrelated with foramen magnum lesion has various causes. Close follow up of the patient is necessary to monitor for recurrence.WoSScopu
