ABSTRACT

BACKGROUND: As Artificial Intelligence and social robots are increasingly used in health and social care, it is imperative to explore the training needs of the workforce, factoring in their cultural background. OBJECTIVES: Explore views on perceived training needs among professionals around the world and how these related to country cultures. DESIGN: Cross-sectional, descriptive, mixed-methods international online survey. METHODS: Descriptive statistical analysis explored the ranking across countries and relationships with three Hofstede cultural dimensions. Thematic analysis was conducted on the open-ended text responses. RESULTS: A sample of N = 1284 participants from eighteen countries. Knowing the capabilities of the robots was ranked as the top training need across all participating countries and this was also reflected in the thematic analysis. Participants' culture, expressed through three Hofstede's dimensions, revealed statistically significant ranking differences. CONCLUSIONS: Future research should further explore other factors such as the level of digital maturity of the workplace. IMPACT STATEMENT: Training needs of health and social care staff to use robotics are fast growing and preparation should factor in patient safety and be based on the principles of person- and culture-centred care.

ABSTRACT

The absolute intensity for the 803-keV γ ray of 210Po was evaluated by α-γ coincidence technique. A liquid sample with a known amount of 210Po embedded in scintillation fluid was measured in a coincidence-based system that comprises a Liquid Scintillator (LS) detector and a High-Purity Germanium (HPGe) detector. A photo-reflector assembly that contains the 210Po sample provides 100% efficiency for detecting the α particles. The combination between the HPGe and the LS detectors allows to reject non-coincident α-γ events while maintaining high resolution γ spectroscopy. Consequently, the faint 803-keV photopeak from 210Po could be observed in a background-free environment, and its intensity could be evaluated with good accuracy. Sample measurements were carried out over nine months to gather statistics and verify the reliability of the experimental procedure. The absolute intensity of the 803-keV line was found to be (1.22 ± 0.03) × 10-5, in excellent agreement with the adopted value in a recent data compilation and consistent with previous experimental works.

ABSTRACT

A ground-level prototype system for low-background measurements was developed and tested. The system consists of a high-purity germanium (HPGe) detector used for detecting γ rays and coupled to a liquid scintillator (LS) used for detecting α and ß particles. Both detectors are surrounded by shielding materials and anti-cosmic detectors ("veto") used to suppress background events. The energy and timestamp of detected α, ß and γ emissions are recorded event-by-event and analyzed offline. By requiring timing coincidence between the HPGe and LS detectors, background events originating from outside the volume of the measured sample can be effectively rejected. The system performance was evaluated using liquid samples containing known activities of an α emitter (241Am) or a ß emitter (60Co) whose decays are accompanied by γ rays. The LS detector was found to provide a solid angle of almost 4π for α and ß particles. Compared to the traditional γ-singles mode, operating the system in coincidence mode (i.e., α-γ or ß-γ) reduced the background counts by a factor of ∼100. Consequently, the minimal detectable activity for 241Am and 60Co was improved by a factor of 9, being 4 mBq and 1 mBq for an 11-d measurement, respectively. Furthermore, by applying a spectrometric cut in the LS spectrum that corresponds to α emission from 241Am, a background reduction factor of ∼2400 (compared to γ-singles mode) was achieved. Beyond low-background measurements, this prototype exhibits additional compelling features, such as the ability to focus on certain decay channels and study their properties. This concept for a measurement system may be of interest to laboratories that monitor environmental radioactivity, studies involving environmental measurements and/or trace-level radioactivity.

ABSTRACT

The absolute intensity for the 'prompt' 140.5 keV gamma-ray of 99Mo was evaluated using the ß-γ coincidence technique. A liquid sample of 99Mo was prepared from a99Mo/99mTc generator and measured in a 4παß(LS)-γ(HPGe) system that comprises a Liquid Scintillator (LS) detector and a High-Purity Germanium (HPGe) detector. The sample was introduced into scintillation fluid embedded in a photo-reflector assembly that provides almost 100% efficiency for detecting ß particles (in the energy range of intreset). The combination of the HPGe and the LS detectors provided a highly effective rejection mechanism for non-coincident events. Thereby, the distinction between the detected 140.5 keV events originating from decays of 99mTc (IT) and those from transitions bypassing the metastable state could be obtained and the 'prompt' intensity was evaluated directly. The system was calibrated for detecting ß particles and γ-rays using radioactive sources of known activities and having identical geometry as the sample containing 99Mo. The absolute intensity of the 'prompt' 140.5 keV was found to be (5.21 ± 0.02stat±0.16sys)%, in good agreement with results from more recently reported works.

ABSTRACT

AIM: To explore nursing and midwifery managers' views regarding obstacles to compassion-giving across country cultures. BACKGROUND: The benefit of compassionate leadership is being advocated, but despite the fact that health care is invariably conducted within culturally diverse workplaces, the interconnection of culture, compassion and leadership is rarely addressed. Furthermore, evidence on how cultural factors hinder the expression of compassion among nursing and midwifery managers is lacking. METHODS: Cross-sectional, exploratory, international online survey involving 1 217 participants from 17 countries. Managers' responses on open-ended questions related to barriers for providing compassion were entered and thematically analysed through NVivo. RESULTS: Three key themes related to compassion-giving obstacles emerged across countries: 1. related to the managers' personal characteristics and experiences; 2. system-related; and 3. staff-related. CONCLUSIONS: Obstacles to compassion-giving among managers vary across countries. An understanding of the variations across countries and cultures of what impedes compassion to flourish in health care is important. IMPLICATIONS FOR NURSING PRACTICE AND POLICY: Nursing mangers should wisely use their power by adopting leadership styles that promote culturally competent and compassionate workplaces with respect for human rights. Policymakers should identify training and mentoring needs to enable the development of managers' practical wisdom. Appropriate national and international policies should facilitate the establishment of standards and guidelines for compassionate leadership, in the face of distorted organizational cultures and system-related obstacles to compassion-giving.

ABSTRACT

BACKGROUND: Compassion is considered the cornerstone of nursing practice. However, the recent failures in delivering high-quality compassionate nursing care in the UK's National Health Service have brought the topic of compassion to the attention of the public, service providers, policy makers and academics. AIM: The aim of this study was to explore the nurses' views and experiences of a number of compassion-related issues in nursing and describe similarities and differences at an international level as well as from the different nursing roles of the participating nurses. METHODS: An exploratory, cross-sectional descriptive study, using the International Online Compassion Questionnaire. A total of 1323 nurses from 15 countries completed the questionnaire. RESULTS: The majority of participants (59.5%) defined compassion as "Deep awareness of the suffering of others and wish to alleviate it" but definitions of compassion varied by country. Of participants, 69.6% thought compassion was very important in nursing and more than half (59.6%) of them argued that compassion could be taught. However, only 26.8% reported that the correct amount and level of teaching is provided. The majority of the participants (82.6%) stated that their patients prefer knowledgeable nurses with good interpersonal skills. Only 4.3% noted that they are receiving compassion from their managers. A significant relationship was found between nurses' experiences of compassion and their views about teaching of compassion. CONCLUSION: Our study is unique in identifying the views and experiences of nurses from 15 different countries worldwide. The findings reveal that compassion is neither addressed adequately in nursing education nor supported in the practice environment by managers. LIMITATIONS: Self-report bias was inherent to our survey study design. Furthermore, the individual cultural differences and similarities in the findings are difficult to extrapolate owing to the fact that our analysis was at country level, as well as at the level of the participating nurses. IMPLICATIONS FOR NURSING POLICY: Understanding the influence of culture on nurses' views about compassion is critical in the current multicultural healthcare environment and merits further research. This will potentially drive changes in nursing education (ensuring that compassion is taught to nurses) and in the way healthcare leaders and managers foster a compassionate culture within their organizations (e.g. by leading by example and compassionate to their staff).

ABSTRACT

We examined the relationship between occupation and clinical characteristics during pregnancy and medical recommendations to stop working. Using a case-control design, we compared 58 working women who had preterm births, with 126 who had delivered at term. All women were interviewed postpartum while still in hospital. There were no differences between the groups with regard to physical activity outside the home, weekly work hours, nor duration of work. Only a small proportion had been exposed to unusually difficult working conditions, to hazardous agents or to a very uncomfortable working environment. Women who had had preterm births were advised more often to leave their jobs or modify their working patterns. Multivariate analysis revealed that the physician's decision to recommend cessation of work was influenced primarily by complications during the current pregnancy. It appears that our patients at risk for preterm birth are probably correctly identified, and receive appropriate guidelines as to working patterns. It is possible that a poor obstetric history or previous abortions may paradoxically have a protective effect, as they influence the physician to recommend cessation of work.

ABSTRACT

The relationship between physical activity at home and at work during pregnancy and preterm birth was studied. Using a case-control design, 99 women who delivered preterm were compared with 189 women who had term deliveries. The risk of preterm birth was tested in relation to characteristics of work in and outside the home. All women were interviewed post-partum before discharge. There were no statistically significant differences between the groups in relation to sociodemographic and obstetrical factors, but level of education was significantly lower in the study group versus the control group (p = 0.001). Women who delivered preterm had devoted less time 3 months prior to delivery to household chores (mean of 3.7 hours vs. 4.8 hours in the control group, p = 0.002). They also had spent less time walking around the home than the controls (1.2 vs. 1.5 hours, p = 0.02). There were no differences between the groups in relation to physical activity outside the home, not during working hours, nor in duration of work. Significantly fewer women who delivered preterm were active in sports (odds ratio 0.22; 95% confidence interval 0.50-0.65; p = 0.002). A low level of education was significantly related to the risk of preterm birth, which may have resulted from lesser compliance with their physician's recommendations. It appears that in women not used to significant physical activity but who had access to adequate prenatal care, physical effort during pregnancy was not related to a higher risk of preterm birth.

ABSTRACT

Multipotent neural progenitors and stem cells may integrate appropriately into the developing and degenerating central nervous system. They may also be effective in the replacement of genes, cells, and nondiffusible factors in either a widespread or a more circumscribed manner, depending on the therapeutic demands of the clinical situation. In addition, they may be uniquely responsive to some types of neurodegenerative conditions. We believe that these various appealing capabilities are the normal expression of basic biologic properties and attributes of a stem cell. The therapeutic utility of some of those properties is illustrated in this review of ongoing work in our laboratory, particularly with regard to spinal dysfunction. In these examples, we believe we have tapped into a mechanism that underlies a remarkable degree of natural plasticity programmed into the nervous system at the cellular level, and we have now exploited those properties for therapeutic ends.

ABSTRACT

Plasma levels of beta-thromboglobin (beta-TH) and of thromboxane B2 (TXB2) and 6-keto-prostaglandin F1-alpha, the stable metabolites of thromboxane A2 and prostacyclin, were determined by radioimmunoassay methods in eight patients with noninsulin-dependent diabetes before and after dietary treatment and after administration of the sulfonylurea drug glibenclamide. Blood examinations were performed when hyperglycemia was detected for the first time, four weeks after a dietary regimen was started, and four and eight weeks after glibenclamide treatment was begun. Drug treatment was instituted because, despite a suitable diet, patients' postprandial blood sugar was higher than 8 mmol/L (145 mg/dl). At the initial examination, elevated TXB2 and beta-TH levels indicating platelet hyperactivity and hyperglycemia were found. TXB2 and beta-TH levels decreased significantly after glibenclamide treatment was started, as did the blood glucose level. There was no change in 6-keto-PGF1-alpha. We interpret these results to indicate that diabetes is associated with hyperactivity of platelet aggregation and that control of blood glucose is important because a lower blood glucose level attenuates platelet hyperactivity. Whether the decrease in platelet hyperactivity is a direct result of the lowered blood sugar or reflects the influence of the drug treatment requires clarification.

ABSTRACT

A case of traumatic complete avulsion of the optic nerve is reported together with fluorescein angiography and electrodiagnostic findings. Despite the disappearance of the central vessels, circulation remained in the branch retinal vessels and angiography demonstrated communication between peripapillary choroidal vessels and the superior temporal artery. The visually-evoked cortical response was abolished. Electroretinography showed a normal a-wave but reduced amplitude b-wave, not supporting the theory of the existence of centrifugal retino-suppressive fibres in the optic nerve of man.

ABSTRACT

A technique for producing steady state visual evoked responses (VERs) to pattern reversal stimulation of retinal areas corresponding to discrete field quadrants is described. Patients examined included 10 normal individuals, 11 patients with ocular hypertension, and 21 with glaucomatous field defects (unilateral except in two cases with bilateral defects). The VERs relating to normal homonymous field quadrants were in phase in all three groups, excluding patients with cataracts. The VERs corresponding to quadrants with small field defects showed a phase shift compared with responses from normal homonymous quadrants in all cases, but were not detectable if the defect filled more than three quarters of the quadrant tested in most cases. The method offers a means for the objective assessment of visual fields in patients with unilateral optic nerve lesions, provided that central visual acuity is 20/80 or better
