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

Dissociative electron attachment to HBr: A temperature effect

The effects of rovibrational temperature on dissociative electron attachment to hydrogen bromide has been investigated from the experimental and theoretical point of view. Theoretical calculations based on the nonlocal resonance model predict a strong temperature effect on the Br⁻ fragment ion yield due to population of higher vibrational and rotational states. A crossed beam experimental setup consisting of a temperature controlled effusive molecular beam and a trochoidal electron monochromator has been used to confirm this prediction. The high degree of agreement between experiment and theory indicates the validity of the theoretical model and its underlying physical picture

Cyclisation oxydative d’hexadiène-1,5.

Cytokinin oxidase/dehydrogenase (CKX) is the only known enzyme involved in cytokinin catabolism. Genes coding for two Arabidopsis CKX isoforms, AtCKX1 and AtCKX2, were introduced separately into a binary cloning vector, immobilized into Agrobacterium tumefaciens strain GV3101, and introduced into root explants of centaury (Centaurium erythraea Rafn.). The integration of each transgene was confirmed by genomic PCR. Of the total transformed explants, 30 and 28.2 % of the transformants carried AtCKX1 and AtCKX2 transgenes, respectively. Of these transformants, 50 % exhibited expression of the AtCKX1 transgene, while 64 % of transformants exhibited expression of the AtCKX2 transgene. For all analysed AtCKX transgenic centaury lines, as well as for untransformed control plants, CKX activity was higher in roots than in shoots. Expression of AtCKX in most transgenic lines contributed to enhanced levels of CKX activity in root tissues; whereas, only a few lines demonstrated increased CKX activity in shoot tissues compared to those of control plants. Moreover, overexpression of AtCKX resulted in reduced morphogenetic potential in transgenic plants, but did not significantly affect biomass production in comparison to untransformed control plants.Ministry of Education, Science and Technological Development of the Republic of Serbia [ON173015]; Czech Science Foundation [P506/11/0774
