Post-intensive care syndrome (PICS) encompasses persistent physical, psychological, and cognitive impairments. The coronavirus disease of 2019 (COVID-19) pandemic highlighted parallels between PICS and "long COVID". There is an overlap between the 2 in risk factors, symptoms, and pathophysiology. Physical impairments in both include weakness and fatigue. Cognitive impairments include executive dysfunction in PICS and "brain fog" in long COVID. Mental health issues consist of depression, anxiety, and posttraumatic stress disorder in both disease states. Long COVID and PICS impact families, with multifaceted effects on physical health, mental well-being, and socioeconomic stability. Understanding these syndromes is crucial for comprehensive patient care and family support., Competing Interests: Disclosure No conflicts of interest disclosed by the authors., (Copyright © 2024 Elsevier Inc.

Introduction: Post intensive care syndrome (PICS) affects an increasing number of critical illness survivors and their families, with serious physical and psychological sequelae. Since little is known about the burden of critical illness on ICU survivor families, we conducted a prospective observational study aiming to assess this, and investigate correlations of the patients' psychometric and health-related quality of life (HRQOL) scores with family burden., Materials and Methods: Twenty-nine patients were evaluated in the presence of a family member. Participants were assessed with the use of validated scales for anxiety, depression, post-traumatic stress disorder, cognitive decline, and the family burden scale (FBS)., Results: High burden was present in 27.6% of family members. Statistically significant correlations were observed between the FBS score and trait anxiety, depression, and the physical and psychological components of HRQOL., Conclusions: Our results suggest that family burden following critical illness is common, suggesting that its assessment should be incorporated in the evaluation of PICS-family in large observational studies., Competing Interests: Conflict of interest None to declare., (© 2022 Vassiliki Mantziou, Charikleia S.

Current achievements in medical science and technological advancements in intensive care medicine have allowed better support of critically ill patients in intensive care units (ICUs) and have increased survival probability. Post-intensive care syndrome (PICS) is a relatively new term introduced almost 10 years ago, defined as "new or worsening impairments in physical, cognitive, or mental health status arising after critical illness and persisting beyond acute care hospitalization". A significant percentage of critically ill patients suffer from PICS for a prolonged period of time, with physical problems being the most common. The exact prevalence of PICS is unknown, and many risk factors have been described well. Coronavirus disease 2019 (COVID-19) survivors seem to be at especially high risk for developing PICS. The families of ICU survivors can also be affected as a response to the stress suffered during the critical illness of their kin. This separate entity is described as PICS family (PICS-F). A multidisciplinary approach is warranted for the treatment of PICS, involving healthcare professionals, clinicians, and scientists from different areas. Improving outcomes is both challenging and imperative for the critical care community. The review of the relevant literature and the study of the physical, cognitive, and mental sequelae could lead to the prevention and timely management of PICS and the subsequent improvement of the quality of life for ICU survivors.

Pharmaceuticals intended for use in patients of childbearing potential need to be tested for teratogenicity before marketing. Several pharmaceutical companies use animal-free in vitro models which allow a more rapid selection of lead compounds and contribute to 3Rs principles ('replace, reduce and refine') by streamlining the selection of promising compounds submitted to further regulatory studies in animals. Currently available in vitro models typically rely on adherent monolayer cultures or disorganized 3D structures, both of which lack the spatiotemporal and morphological context of the developing embryo. A newly developed 3D 'gastruloid' model has the potential to achieve a more reliable prediction of teratogenicity by providing a robust recapitulation of gastrulation-like events alongside morphological coordination at relatively high-throughput. In this first proof-of-concept study, we used both mouse and human gastruloids to examine a panel of seven reference compounds, with associated in vivo data and known teratogenic risk, to quantitatively assess in vitro teratogenicity. We observed several gross morphological effects, including significantly reduced elongation or decreased size of the gastruloids, upon exposure to several of the reference compounds. We also observed aberrant gene expression using fluorescent reporters, including SOX2, BRA, and SOX17, suggestive of multi-lineage differentiation defects and disrupted axial patterning. Finally, we saw that gastruloids recapitulated some of the known in vivo species-specific susceptibilities between their mouse and human counterparts. We therefore suggest that gastruloids represent a powerful tool for teratogenicity assessment by enabling relevant physiological recapitulation of early embryonic development, demonstrating their use as a novel in vitro teratogenic model system., (Copyright © 2021.

The physical and psychological consequences of critical illness may affect intensive care unit survivors for up to five years, and hence, health-related quality of life has emerged as an important measure of outcome in this population. We aimed at investigating the quality of life, the presence of anxiety and depression symptoms, and the correlations of clinical and psychological parameters with the quality of life scores in survivors of critical illness one year after discharge from intensive care. Widely used scales that have been validated for the Greek population were used. One thousand two hundred and seventy (1270) patients were assessed for eligibility. Inclusion criteria were age between 18 and 68 years and the presence of critical illness requiring endotracheal intubation and mechanical ventilation for more than three days. One hundred and four (104) patients were included in the final analysis; forty-nine age and sex-matched healthy volunteers were included for comparison. One year following intensive care unit discharge, survivors of critical illness had impaired quality of life scores, as measured with the WHOQOL-Bref, compared to healthy subjects ( p < 0.001 for the physical and psychological domains, and p = 0.006 for the domain of social relationships). In addition, we found that quality of life scores were significantly lower in patients with comorbidities ( p < 0.01), and correlated with the duration of ICU stay (r = -0.19, p = 0.04) and with the presence of symptoms suggestive of depression (r = -0.66, p < 0.0001) and post-traumatic stress disorder (r = -0.61, p < 0.0001). Approximately one-third of our patients scored high in the CES-D scale for depression, while the majority of them scored high in the STAI scale for anxiety symptoms.

Technical and ethical limitations create a challenge to study early human development, especially following the first 3 weeks of development after fertilization, when the fundamental aspects of the body plan are established through the process called gastrulation. As a consequence, our current understanding of human development is mostly based on the anatomical and histological studies on Carnegie Collection of human embryos, which were carried out more than half a century ago. Due to the 14-day rule on human embryo research, there have been no experimental studies beyond the fourteenth day of human development. Mutagenesis studies on animal models, mostly in mouse, are often extrapolated to human embryos to understand the transcriptional regulation of human development. However, due to the existence of significant differences in their morphological and molecular features as well as the time scale of their development, it is obvious that complete knowledge of human development can be achieved only by studying the human embryo. These studies require a cellular framework. Here we summarize the cellular, molecular, and temporal aspects associated with human gastrulation and discuss how they relate to existing human PSCs based models of early development., (Copyright © 2021 Elsevier Inc.

Introduction: Healthcare professionals who are directly involved in the diagnosis, treatment, and general care of patients with SARS-CoV-2 are at risk of developing adverse psychological reactions. A cross-sectional study of healthcare professionals aimed to determine the impact of the SARS-CoV-2 pandemic on the mental health of healthcare professionals in two of the largest referral hospitals in Athens, Greece., Methods: The study was conducted in the two largest SARS-CoV-2 referral hospitals in Athens, Greece. An assessment and the interrelationship of post-traumatic stress disorder, using the Impact of Event Scale-Revised [IES-R]) and burnout, using the Maslach Burnout Inventory [MBI]) was carried out., Results: A total of 162 subjects were enrolled in the study. Fifty-six (35%) had an IES-R score > 33, suggesting post-traumatic stress disorder. Forty-nine (30%) had an MBI score > 27. Seventy-five (46%) had a personal accomplishment score of < 33 and 46 (28%) had a depersonalization score >10. Stepwise backward logistic regression revealed that the only independent variable that was retained regarding the presence of post-traumatic stress disorder was the emotional exhaustion score of the MBI (at a cut-off of 24 in this scale, the 95% CI of the odds ratio for the presence of post-traumatic stress disorder was 1.077-1.173)., Conclusions: In this sample of first-line Greek healthcare professionals against SARS-CoV-2, most of them were proven to be quite resilient to this challenge. One-third of them had post-traumatic stress disorder, which depended on their degree of emotional exhaustion. Healthcare professionals, as represented by this study, performed their duties without feeling helpless and developing adverse psychological reactions., Competing Interests: Conflict of interest None to declare., (© 2021 Ioannis Ilias, Vassiliki Mantziou, Efstratios Vamvakas, Efstathia Kampisiouli, Maria Theodorakopoulou, Chariklia Vrettou, Evangelia Douka, Alice G.

Childhood exposure to secondhand smoke (SHS) is a serious threat to public health and can be influenced by parental lifestyle habits and beliefs. Taking the above into account we aimed at locating predictors of parental induced exposure to SHS in the house and family car among 614 children who visited the emergency department of two large pediatric hospitals in Athens, Greece. The multivariate analysis revealed that the factors found to mediate household exposure to paternal SHS were the number of cigarettes smoked per day (O.R 1.13, p<0.001) while, having a non-smoking spouse had a protective effect (O.R 0.44, p=0.026). Maternally induced household SHS exposure was related to cigarette consumption. For both parents, child exposure to SHS in the family car was related to higher numbers of cigarettes smoked (p<0.001), and for fathers was also more often found in larger families. Additionally, lower educated fathers were more likely to have a spouse that exposes their children to SHS inside the family car (O.R 1.38 95%C.I: 1.04-1.84, p=0.026). Conclusively, efforts must be made to educate parents on the effects of home and household car exposure to SHS, where smoke free legislation may be difficult to apply.

In a population-based longitudinal cohort study, we tested the hypothesis that children growing up in a high-traffic polluted urban area (UA) in the Athens' basin have higher prevalence of allergies and sensitization when compared with those growing up in a Greek provincial rural area (RA). We recruited 478 and 342 children aged 8-10 living in the UA and the RA, respectively. Respiratory health was assessed by a parent-completed questionnaire in three phases: 1995-96 (phase 1), 1999-2000 (phase 2), 2003-04 (phase 3) and skin-prick testing to common indoor and outdoor aeroallergens was performed at phases 1 and 2. Reported asthma and eczema did not differ between the two areas, whereas reported hay fever was persistently more prevalent in the UA than in the RA (16.5%, 17.0%, 18.2% vs. 7.0%, 8.3%, 9.6%, respectively). Sensitization was more prevalent in the UA at both phases (19.0% vs. 12.1% in phase 1, 20.0% vs. 14.1% in phase 2). Residential area contributed independently to sensitization to >or=1 aeroallergens (OR: 0.29; 95% CI: 0.13-0.66; p = 0.003) and to polysensitization (OR: 0.28; 95% CI: 0.10-0.82; p = 0.020) in phase 1. These associations were independent of farming practices. No significant contributions were found in phase 2. Our results suggest that long-term exposure to urban environment is associated with a higher prevalence of hay fever but not of asthma or eczema. The negative association between rural living and the risk of atopy during childhood, which is independent of farming practices, implies that it is mainly driven by an urban living effect.

The purpose of this study was to examine and compare the attitudes of registered nurses and student nurses towards disabled children. A convenience sample consisting of 99 registered nurses employed in paediatric hospitals and 189 student nurses was selected. The instrument used for data collection was the 'Attitudes Towards Disabled Persons' (ATDP) scale. Descriptive statistics and one-way analysis of variance were performed to test for significant differences. On the whole subjects' attitudes appeared to be poor. Student nurses had more positive attitudes in comparison to registered nurses; however, the difference was not statistically significant. There were significant differences between the different age groups and between student groups within different education settings. There were no significant differences in gender. Actions to improve subjects' attitudes towards disabled children are discussed and suggested.
