ABSTRACT

The severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection can be asymptomatic or cause a disease (COVID-19) characterized by different levels of severity. The main cause of severe COVID-19 and death is represented by acute (or acute on chronic) respiratory failure and acute respiratory distress syndrome (ARDS), often requiring hospital admission and ventilator support.The molecular pathogenesis of COVID-19-related ARDS (by now termed c-ARDS) is still poorly understood. In this review we will discuss the genetic susceptibility to COVID-19, the pathogenesis and the local and systemic biomarkers correlated with c-ARDS and the therapeutic options that target the cell signalling pathways of c-ARDS.

ABSTRACT

Purpose: The COVID-19 pandemic restrictions had negative impact on the psychopathology of people with Eating Disorders (EDs). Factors involved in the vulnerability to stressful events have been under-investigated in this population. We aimed to assess which factors contributed to COVID-19-induced worsening in both general and specific psychopathology. Methods: Three-hundred and twelve people with a clinically defined diagnosis of an ED and undergoing a specialist ED treatment in different Italian ED services before the spreading of COVID-19 pandemic filled in an online survey. ED specific and general psychopathology changes after COVID-19 quarantine were retrospectively evaluated. Factors related to COVID-19 concerns (financial condition, fear of contagion, perceived social isolation/support, satisfaction in peer, family or sentimental relationships), illness duration and treatment-related variables (type of treatment provided, type of access to care, satisfaction with therapeutic relationships) were included as predicting factors in a structural equational model, which included latent variables consisting of general and ED psychopathology items as outcomes. Results: A perceived low quality of therapeutic relationships, fear of contagion and increased isolation were positively associated with psychopathology worsening. Reduced satisfaction with family and with friends' relationships and reduced perceived social support were associated with ED and general symptoms deterioration, respectively. No significant effect emerged for intimate relationships, illness duration, economic condition and type of treatment. Conclusions: This study provides a comprehensive evaluation of clinical variables associated with psychopathological changes during the COVID-19 lockdown period highlighting potential risk and resilience factors and, possibly, informing treatment as well as prevention strategies for EDs. Level of evidence IV: Evidence obtained from multiple time series analysis such as case studies. (PsycInfo Database Record (c) 2022 APA, all rights reserved)

ABSTRACT

Disseminated intravascular coagulation (DIC) is a severe condition characterized by the systemic formation of microthrombi complicated with bleeding tendency and organ dysfunction. In the last years, it represents one of the most frequent consequences of coronavirus disease 2019 (COVID-19). The pathogenesis of DIC is complex, with cross-talk between the coagulant and inflammatory pathways. The objective of this study is to investigate the anti-inflammatory action of ultramicronized palmitoylethanolamide (um-PEA) in a lipopolysaccharide (LPS)-induced DIC model in rats. Experimental DIC was induced by continual infusion of LPS (30 mg/kg) for 4 h through the tail vein. Um-PEA (30 mg/kg) was given orally 30 min before and 1 h after the start of intravenous infusion of LPS. Results showed that um-PEA reduced alteration of coagulation markers, as well as proinflammatory cytokine release in plasma and lung samples, induced by LPS infusion. Furthermore, um-PEA also has the effect of preventing the formation of fibrin deposition and lung damage. Moreover, um-PEA was able to reduce the number of mast cells (MCs) and the release of its serine proteases, which are also necessary for SARS-CoV-2 infection. These results suggest that um-PEA could be considered as a potential therapeutic approach in the management of DIC and in clinical implications associated to coagulopathy and lung dysfunction, such as COVID-19.

ABSTRACT

BACKGROUND: We assessed the impact of the coronavirus disease 2019 (COVID-19) pandemic on specific Eating Disorder (ED) and general psychopathology in people with an ED diagnosis during the lockdown period and after the end of the related containment measures. METHODS: People with clinically defined diagnosis and undergoing treatment for an ED completed an online survey, which included adapted questions from standardized psychometric scales. Data relative to three different time periods (before, during and after the end of lockdown) were collected. Psychopathological changes over these periods were investigated and compared through one-way analysis of variance or covariance with repeated measures. RESULTS: Three hundred twelve people completed the survey (57.4% diagnosed with Anorexia Nervosa (AN) or atypical AN, 20.2% with Bulimia Nervosa, 15.4% with Binge Eating Disorder, 7.05% with Other Specified Feeding or Eating Disorders). The severity of both specific and general psychopathology increased during the lockdown and the rise of general symptoms persisted in the following re-opening phase, except for suicide ideation. Almost all of these findings were not affected by ED diagnosis, participants' age and illness duration. LIMITATIONS: The retrospective nature of data collection is the main limitation of the study. CONCLUSIONS: People with EDs showed a COVID-19 emergency-induced worsening of both general and specific psychopathology. The effect on general psychopathology persisted in the re-opening period. These findings suggest a high stress vulnerability of ED individuals with important effects on internalizing symptoms, which are worth of attention by clinicians.
