Pregnancy-specific responses to COVID-19 revealed by high-throughput proteomics of human plasma.

BACKGROUND: Pregnant women are at greater risk of adverse outcomes, including mortality, as well as obstetrical complications resulting from COVID-19. However, pregnancy-specific changes that underlie such worsened outcomes remain unclear. METHODS: Plasma samples were collected from pregnant women and non-pregnant individuals (male and female) with (n = 72 pregnant, 52 non-pregnant) and without (n = 29 pregnant, 41 non-pregnant) COVID-19. COVID-19 patients were grouped as asymptomatic, mild, moderate, severe, or critically ill according to NIH classifications. Proteomic profiling of 7,288 analytes corresponding to 6,596 unique protein targets was performed using the SOMAmer platform. RESULTS: Herein, we profile the plasma proteome of pregnant and non-pregnant COVID-19 patients and controls and show alterations that display a dose-response relationship with disease severity; yet, such proteomic perturbations are dampened during pregnancy. In both pregnant and non-pregnant state, the proteome response induced by COVID-19 shows enrichment of mediators implicated in cytokine storm, endothelial dysfunction, and angiogenesis. Shared and pregnancy-specific proteomic changes are identified: pregnant women display a tailored response that may protect the conceptus from heightened inflammation, while non-pregnant individuals display a stronger response to repel infection. Furthermore, the plasma proteome can accurately identify COVID-19 patients, even when asymptomatic or with mild symptoms. CONCLUSION: This study represents the most comprehensive characterization of the plasma proteome of pregnant and non-pregnant COVID-19 patients. Our findings emphasize the distinct immune modulation between the non-pregnant and pregnant states, providing insight into the pathogenesis of COVID-19 as well as a potential explanation for the more severe outcomes observed in pregnant women.

Pregnant COVID-19 patients are at increased risk of experiencing complications and severe outcomes compared to the general population. However, the reasons for this heightened risk are still unclear. We measured the proteins present in the blood of pregnant and non-pregnant patients with COVID-19 and compared these to healthy individuals. We found that some COVID-19-associated proteins were present at lower levels in pregnant women, which could help to protect the fetus from harmful inflammation, the body's natural response to infection. While some proteins affected by COVID-19 are shared between pregnant and non-pregnant patients, others were distinctly affected only in pregnant women, providing a potential explanation for the more severe outcomes in this group.

Risk perception and affective state on work exhaustion in obstetrics during the COVID-19 pandemic

A multicenter cross-sectional survey study involving four Italian University Hospitals was performed to test the hypothesis that negative affect and positive affect (affective dimensions) mediate the association between risk perception (perceived risk of infection and death;cognitive dimensions) and the feeling of work exhaustion (WE) among obstetrics healthcare providers (HCPs) during the Coronavirus Disease 2019 (COVID-19) pandemic. Totally, 570 obstetrics HCPs were invited to complete the 104-item IPSICO survey in May 2020. A theoretical model built on the tested hypothesis was investigated by structural equation modelling. The model explained 32.2% of the WE variance. Only negative affect mediated the association between cognitive dimensions and WE and also the association between WE and psychological well-being before the pandemic, experiences of stressful events, female gender, and dysfunctional coping. Non-mediated associations with WE were observed for work perceived as a duty, experience of stressful events, support received by colleagues, and the shift strategy. Only previous psychological well-being, support by colleagues, and shift strategies were inversely associated with WE. Based on study results, monitoring negative than positive affect appears superior in predicting WE, with practical implications for planning psychological interventions in HCPs at the individual, interpersonal, and organizational levels.

Practice changes in Italian Gynaecologic Units during the COVID-19 pandemic: a survey study.

The impact of Coronavirus disease 2019 pandemic on Italian Gynaecological Units practice and the compliance and satisfaction with available guidelines/recommendations is unknown. Therefore, a survey was conducted among all Italian Gynaecological Units Directors in April 2020. The response rate was 90% (135/150). 77.8% of centres performed surgery only for oncologic or not deferrable pathologies, and 9.6% was closed. 68.7% of directors were at least moderately satisfied by published guidelines/recommendations, but 94.8% of respondents identified limitations, mainly (83%) the absent definition of benign non-deferrable pathology. Responders considered as non-deferrable severe endometriosis (69.6%), endometriosis with organ failure/dysfunction (74.1%), and unresponsive symptomatic fibroids (89.6%). Despite guidelines/recommendations, respondents treated ovarian (77%) and endometrial (71.6%) cancer as usual. Only a minority of respondents reduced the laparoscopic approach (11.2%) and adopted all recommended surgical precautions (9.6%). Compliance with available guidelines/recommendations appears incomplete. Reconsidering guidelines/recommendations regarding oncological cases and specify non-deferrable benign pathologies would improve guidelines/recommendations compliance.Impact statementWhat is already known on this subject? The SARS-CoV-2 pandemic has profoundly influenced medical routine practice worldwide. Surgery units have been forced to reduce or even completely restrict their activity to re-allocate human resources. Many major international gynaecological societies have released statements and guidelines, providing various recommendations to guide practice changes. However, the impact of the SARS-CoV-2 pandemic on Italian Gynaecological Units practice and the compliance and satisfaction with available guidelines/recommendations is unknown.What do the results of this study add? Study results provide evidence showing how the SARS-CoV-2 pandemic has changed surgical activity in the Italian Gynaecological Units. Most centres reduced surgical activity, limiting surgery only for oncologic or not deferrable pathologies. Moreover, our research shows the level of compliance and satisfaction with available guidelines/recommendations and where they need to be improved. Most directors were at least moderately satisfied but identified different limitations. Guidelines/recommendations do not provide enough details, such as the absent definition of benign non-deferrable pathologies.What are the implications of these findings for clinical practice and/or further research? The limited compliance with available guidelines/recommendations and identified limitations suggest reconsidering guidelines/recommendations focussing on identified gaps. Provide more details, such as specifying non-deferrable benign pathologies, would improve guidelines/recommendations compliance.
