ABSTRACT

Workplace bullying is common among nurses and negatively affects several work-related variables, such as job burnout and job satisfaction. However, no study until now has examined the impact of workplace bullying on quiet quitting among nurses. Thus, our aim was to examine the direct effect of workplace bullying on quiet quitting and to investigate the mediating effect of coping strategies on the relationship between workplace bullying and quiet quitting in nurses. We conducted a cross-sectional study with a convenience sample of 650 nurses in Greece. We collected our data in February 2024. We used the Negative Acts Questionnaire-Revised, the Quiet Quitting Scale, and the Brief COPE to measure workplace bullying, quiet quitting, and coping strategies, respectively. We found that workplace bullying and negative coping strategies were positive predictors of quiet quitting, while positive coping strategies were negative predictors of quiet quitting. Our mediation analysis showed that positive and negative coping strategies partially mediated the relationship between workplace bullying and quiet quitting. In particular, positive coping strategies caused competitive mediation, while negative coping strategies caused complimentary mediation. Nurses' managers and policy makers should improve working conditions by reducing workplace bullying and strengthening positive coping strategies among nurses.

ABSTRACT

The existing 3D printing methods exhibit certain fabrication-dependent limitations for printing curved constructs that are relevant for many tissues. Four-dimensional (4D) printing is an emerging technology that is expected to revolutionize the field of tissue engineering and regenerative medicine (TERM). 4D printing is based on 3D printing, featuring the introduction of time as the fourth dimension, in which there is a transition from a 3D printed scaffold to a new, distinct, and stable state, upon the application of one or more stimuli. Here, we present an overview of the current developments of the 4D printing technology for TERM, with a focus on approaches to achieve temporal changes of the shape of the printed constructs that would enable biofabrication of highly complex structures. To this aim, the printing methods, types of stimuli, shape-shifting mechanisms, and cell-incorporation strategies are critically reviewed. Furthermore, the challenges of this very recent biofabrication technology as well as the future research directions are discussed. Our findings show that the most common printing methods so far are stereolithography (SLA) and extrusion bioprinting, followed by fused deposition modelling, while the shape-shifting mechanisms used for TERM applications are shape-memory and differential swelling for 4D printing and 4D bioprinting, respectively. For shape-memory mechanism, there is a high prevalence of synthetic materials, such as polylactic acid (PLA), poly(glycerol dodecanoate) acrylate (PGDA), or polyurethanes. On the other hand, different acrylate combinations of alginate, hyaluronan, or gelatin have been used for differential swelling-based 4D transformations. TERM applications include bone, vascular, and cardiac tissues as the main target of the 4D (bio)printing technology. The field has great potential for further development by considering the combination of multiple stimuli, the use of a wider range of 4D techniques, and the implementation of computational-assisted strategies.

ABSTRACT

Background: Alexithymia and atypical gut-brain signaling have been linked to the pathophysiology of inflammatory bowel disease (IBD). We herein assessed IBD patients' alexithymia levels and interoceptive abilities, and detected potential correlations with psychological distress, symptom severity and disease activity, and inflammation indices. Methods: Adult IBD outpatients and healthy controls were recruited. Alexithymia was assessed using the Toronto Alexithymia Scale, interoceptive accuracy using the Heartbeat Counting Test (cardiac interoception) and the Water Load Test-II (gastric interoception), and interoceptive sensibility using the Multidimensional Assessment of Interoceptive Awareness (MAIA). Results: Forty-one patients with Crohn's disease (CD), 16 with ulcerative colitis (UC), and 50 healthy controls were included. In CD patients, the level of externally oriented thinking and total alexithymia score were correlated with disease activity (P=0.027 and P=0.047, respectively), while in UC patients difficulties in identifying emotions were linked to disease activity (P=0.007). In CD patients, the Noticing, Not-Worrying and Emotional Awareness MAIA subscale score were correlated with C-reactive protein levels (P=0.005, P=0.048 and P=0.005), the Noticing subscale score with interleukin (IL)-1ß levels (r=-0.350, P=0.039), the Not-Distracting subscale score with IL-6 levels (r=-0.402, P=0.017), and the Emotional Awareness subscale score with IL-1ß (r=-0.367, P=0.030) and IL-6 (r=-0.379, P=0.025) levels. Finally, in UC patients, the Not-Worrying subscale score was significantly associated with IL-6 levels (r=-0.532, P=0.049), while difficulties in identifying emotions were linked to IL-8 levels (r=0.604, P=0.022). Conclusion: Emotional and interoceptive processing is associated with IBD disease activity, suggesting a potential implication for IBD pathophysiology.

ABSTRACT

The National Institute for Clinical Excellence (NICE) now recommends that continuous glucose monitoring (CGM) be offered to adults and children with diabetes who are at risk from hypoglycaemia. Hypoglycaemia is common in the neonatal period, and is a preventable cause of poor neurodevelopmental outcome, but is CGM helpful in the management of neonates at risk of hypoglycaemia? Neonatal studies have shown that CGM can detect clinically silent hypoglycaemia, which has been associated with reduced executive and visual function in early childhood. Intervention trials have further shown CGM can support the targeting of glucose levels in high-risk extremely preterm neonates. In spite of significant advances in technology, including smaller sensors, better accuracy and factory calibration, further progress and adoption into clinical practice has been limited as current devices are not designed nor have regulatory approval for the specific needs of the newborn. The use of CGM has the potential to support clinical management, and prevention of hypoglycaemia but must be set within its current limitations. The data CGM provides however also provides an important opportunity to improve our understanding of potential risks of hypoglycaemia and the impact of clinical interventions to prevent it.

ABSTRACT

OBJECTIVES: Glucose dysregulation is common in infants with hypoxic ischaemic encephalopathy (HIE) and is likely to exacerbate cerebral injury. Infrequent measurement of glucose concentrations makes both identification and prevention of this risk challenging. Continuous glucose monitoring (CGM) has the potential to address both these challenges, but has not been explored in these infants. We aimed to evaluate the feasibility and potential impact of real-time CGM in term infants with HIE being treated with therapeutic hypothermia (TH). DESIGN: Feasibility study. SETTING: Tertiary-level neonatal unit, UK. PATIENTS: Term infants with HIE undergoing TH. INTERVENTION: A CGM sensor was inserted within 48 hours of birth and kept in situ for the first week of life. Clinical staff were blinded to the CGM recordings and clinical decisions were based on blood glucose assays. MAIN OUTCOME MEASURES: (1) Accuracy of CGM values during and post TH, (2) Per cent of time spent outside the clinical range (2.6-10 mmol/L), (3) Episodes of hypoglycaemia and hyperglycaemia, (4) Adverse effects. RESULTS: The accuracy of CGM values during TH were comparable to those when infants were normothermic. There was wide variation in per cent time outside the target range (2.6-10 mmol/L) between infants (median 5%, range 0%-34%). CGM identified 44% of infants with ≥1 episode of hypoglycaemia (<2.6 mmol/L) and 50% with ≥1 episode of hyperglycaemia (>10 mmol/L). No adverse events were observed. CONCLUSIONS: This study demonstrates that CGM could be a useful adjunct for glucose monitoring in babies undergoing TH who are at risk of both hypoglycaemia and hyperglycaemia.

ABSTRACT

3D bioprinting is usually implemented on flat surfaces, posing serious limitations in the fabrication of multilayered curved constructs. 4D bioprinting, combining 3D bioprinting with time-dependent stimuli-induced transformation, enables the fabrication of shape-changing constructs. Here, a 4D biofabrication method is reported for cartilage engineering based on the differential swelling of a smart multi-material system made from two hydrogel-based materials: hyaluronan and alginate. Two ink formulations are used: tyramine-functionalized hyaluronan (HAT, high-swelling) and alginate with HAT (AHAT, low-swelling). Both inks have similar elastic, shear-thinning, and printability behavior. The inks are 3D printed into a bilayered scaffold before triggering the shape-change by using liquid immersion as stimulus. In time (4D), the differential swelling between the two zones leads to the scaffold's self-bending. Different designs are made to tune the radius of curvature and shape. A bioprinted formulation of AHAT and human bone marrow cells demonstrates high cell viability. After 28 days in chondrogenic medium, the curvature is clearly present while cartilage-like matrix production is visible on histology. A proof-of-concept of the recently emerged technology of 4D bioprinting with a specific application for the design of curved structures potentially mimicking the curvature and multilayer cellular nature of native cartilage is demonstrated.

ABSTRACT

Nowadays, prevention, control and treatment of cervical cancer are a worldwide public health priority. Primary objective of this study was to evaluate the level of awareness of female Syrian refugees who have recently settled in Greece regarding the warning signs and the risk factors of cervical cancer. This is a descriptive, cross-sectional study that was conducted in two facilities of the Hellenic Red Cross. The Cervical Cancer Awareness Measure questionnaire was addressed to 176 female Syrian refugees, aged between 18 and 50. Syrian women presented low awareness both for risk factors and warning signs. The most frequently identified warning signs were vaginal bleeding after menopause (44.3%), vaginal bleeding between menstruation (34.1%) and unexplained weight loss (32.4%). Regarding the risk factors' recognition rates, 74.5% considered the existence of many sexual partners as a risk factor and 61.3% the existence of a sexual partner with many previous sexual partners. Older age, a higher level of education and confidence that any potential symptom would be identified were associated with increased awareness. Our findings confirm former published reports that indicate poor awareness regarding cervical cancer among refugee populations. Full compliance with the guidelines of the World Health Organization for a national cervical cancer screening programme is highly advised in Greece and should address the needs of both native and refugee populations. This research is the first one that underlines the need for raising awareness of cervical cancer among female Syrian refugees in Greece by developing health promotion strategies adjusted to their unique cultural needs.

ABSTRACT

BACKGROUND: SARS-CoV-2 has rapidly spread worldwide, threatening public health and financial and social life. AIMS: The current study's aim was to determine the prevalence of psychological distress and post-traumatic stress symptoms in the Greek population during the first COVID-19 lockdown, and to detect potential correlates. METHOD: An anonymous online survey was conducted between 10 April and 4 May 2020, to collect information regarding people's psychological functioning and COVID-19-related perceptions. RESULTS: A total of 1443 individuals completed the survey; 293 (20%) reported clinically significant anxiety symptoms, 188 (12.9%) reported clinically significant depressive symptoms and 506 (36.4%) suffered from definite post-traumatic stress disorder. Anxiety symptoms were independently associated with female gender (ß = 1.281, 95% CI 0.808-1.755, P < 0.001), educational level (ß = -1.570, 95% CI -2.546 to -0.595, P = 0.002), perceived severity (ß = -1.745, 95% CI -3.146 to -0.344, P = 0.015) and COVID-19-related worry (ß = 7.633, 95% CI 6.206-9.060, P < 0.001). Depressive symptoms were strongly correlated with educational level (ß = -1.298, 95% CI -2.220 to -0.377, P = 0.006), perceived severity (ß = -1.331, 95% CI -2.579 to -0.082, P = 0.037) and COVID-19-related worry (ß = 4.102, 95% CI 2.769-5.436, P < 0.001). Finally, post-traumatic stress symptoms were linked to female gender (ß = 6.451, 95% CI 4.602-8.299, P < 0.001), educational level (ß = -5.737, 95% CI -9.479 to -1.996, P = 0.003), psychiatric history (ß = -4.028, 95% CI -6.274 to -1.782, P < 0.001) and COVID-19-related worry (ß = 23.865, 95% CI 18.201-29.530, P < 0.001). CONCLUSIONS: A significant percentage of the population reported clinically important anxiety, depressive and post-traumatic stress symptoms. Women, less-educated individuals and people with a psychiatric history appeared more vulnerable to the pandemic's psychological impact.

ABSTRACT

BACKGROUND: In recent years, the adoption of unhealthy dietary habits and a sedentary lifestyle has led to an alarming increase in the prevalence of non-alcoholic fatty liver disease (NAFLD) in pediatric populations. Hepatic steatosis is now considered the most common cause of chronic liver disease in children and adolescents and may progress to liver fibrosis and even cirrhosis, increasing long-term mortality rates. Apart from its severe medical co-morbidities, pediatric NAFLD is associated with a variety of psychosocial factors which act either as precipitants or consequences of the disease. OBJECTIVE: Studying these parameters might expand our understanding of NAFLD pathogenesis and provide a framework for more effective management. METHOD: In this context, we performed a literature review focusing on the associations of pediatric NAFLD with psychosocial parameters to detect and integrate the most recent data on this topic and provide a scaffold for further conceptualization and research. RESULTS: There are a limited number of studies addressing issues of psychosocial functioning in children with NAFLD. Pediatric NAFLD is frequently accompanied by neuropsychiatric symptoms and poor quality of life and the level of impairment does not correlate with the degree of hepatic damage. In addition, mentally and intellectually-impaired youth appear at greater risk for developing liver steatosis. CONCLUSIONS: Pediatric NAFLD is associated with psychosocial parameters in a bidirectional way. Further research is needed on NAFLD's psychosocial correlates and on the effect of treatment on patients' well-being.

ABSTRACT

BACKGROUND: To conduct a cost-utility analysis of ranibizumab versus aflibercept for the treatment of patients with visual impairment due to diabetic macular edema (DME) in the Greek setting. METHODS: A Markov model was adapted to compare the use of ranibizumab 0.5 mg (pro re nata-PRN and treat and extend-T&E) to aflibercept 2 mg (every 8 weeks after five initial doses) in DME. Patients transitioned at a 3-month cycle among nine specified health states (including death) over a lifetime horizon. Transition probabilities, utilities, as well as DME-related mortality were extracted from relevant clinical trials, a network meta-analysis and other published studies. The analysis was conducted from payer perspective and as such only costs reimbursed by the payer were considered (year 2014). The incremental cost per quality-adjusted life year (QALY) gained and the net monetary benefit was the main outcome measures. RESULTS: Τhe use of PRN and T&E ranibizumab regimens were shown to be cost saving comparing to aflibercept (by €2824 and €22, respectively), and more beneficial in terms of QALYs gained (+0.05) and time without visual impairment (0.031 and 0.034 years), thereby dominating aflibercept. Moreover, ranibizumab used as PRN or T&E resulted in a net monetary benefit of €3984 and €1278, respectively. CONCLUSIONS: Both PRN and T&E ranibizumab regimens were more beneficial and less costly compared to aflibercept for the management of DME. Hence, ranibizumab seems to be a dominant option for the treatment of visual impairment due to DME in the Greek setting.
