Incidence, patterns, risk factors, and histopathological findings of liver injury in coronavirus disease 2019 (COVID-19): a scoping review

BACKGROUND

Coronavirus disease 2019 (COVID-19) exhibits many extrapulmonary manifestations, including liver injury. This scoping review aimed to provide insight into the incidence, patterns, risk factors, histopathological findings, and relationship with disease severity of COVID-19-associated liver injury. Furthermore, we identified existing gaps in the research on the hepatic manifestations of COVID-19 and highlighted areas for future investigations.

METHODS

A scoping review was conducted following the methodological framework suggested by Arksey and O'Mallay. Five online databases, along with grey literature, were searched for articles published until 22 May 2020, and we included 62 articles in the review. The research domains, methodological characteristics, and key conclusions were included in the analysis.

RESULTS

Retrospective observational studies comprised more than one third (41.9%) of the included publications, and 77.8% were conducted on living patients. The incidence of liver injury varied widely across the studies (4.8%-78%), and liver injury was frequently associated with severe COVID-19. We identified the following risk factors for liver injury: male sex, lymphopoenia, gastrointestinal involvement, old age, increased neutrophil count, and the use of hepatotoxic drugs. Histopathological findings indicate that COVID-19 has direct cytopathic effects and causes liver function test derangements secondary to inflammation, hypoxia, and vascular insult.

CONCLUSIONS

Liver injury following COVID-19 infection is common and primarily hepatocellular, with a greater elevation of aspartate aminotransferase tahn of alanine aminotransferase. However, the evidence regarding hepatic failure secondary to COVID-19 is insufficient. Standardised criteria to diagnose liver injury need to be devised. Current use of hepatotoxic drugs necessitates close monitoring of liver function.

Heat, heatwaves and cardiorespiratory hospital admissions in Helsinki, Finland

Background

There is a lack of knowledge concerning the effects of heat on morbidity in Northern Europe. Therefore, this study aimed to evaluate the relationships of daily summer-time temperature and heatwaves with cardiorespiratory hospital admissions in Helsinki, Finland.

Methods

Time-series models adjusted for potential confounders such as air pollution were used to investigate the associations of daily temperature and heatwaves with cause-specific cardiorespiratory hospital admissions, during the summer months of 2000-2017. Daily number of hospitalizations was obtained from the national hospital discharge register, weather information from the Finnish meteorological institute.

Results

Heatwave-days were associated with an increased risk of pneumonia (RR: 1.17, 95%CI: 1.04-1.31), any respiratory disease in some age groups, and myocardial infarction (RR: 1.54, 95% CI: 1.12-2.12) among person 65-74 years of age. In addition, high effect estimates were observed for many types of cardiorespiratory diseases in association with heatwaves in some age-groups. In contrast, risk of arrhythmia was decreased during heatwaves (RR: 0.81, 95% CI: 0.70-0.93).

Conclusions

We found no associations and even protective associations between daily mean temperature and cardiorespiratory hospital admissions. However, our results suggest that heatwaves are a serious health threat affecting the morbidity even in the Northern climate

Key messages

Heatwaves are associated with increased risk of cardio-respiratory hospital admissions. There is a need to adapt to climate change in the public health sector also in Northern Europe to protect vulnerable population groups.

Interpersonal sensitivity in the at-risk mental state for psychosis in Karachi, Pakistan

Introduction

Interpersonal sensitivity can be explained as a personality trait in which there is an excessive and expanded awareness of the behavior and emotions of others. Individuals having high interpersonal sensitivity are sensitive to interpersonal relationships and self-deficiencies in comparison to others. Studies report that high interpersonal sensitivity can cause low self-esteem and feelings of insecurity.

Objectives

The objective of this study was to examine the level of interpersonal sensitivity in individuals with an at-risk mental state (ARMS) for psychosis compared to the individuals not at risk for psychosis.

Methods

A total sample of 50 individuals was recruited from Bahria University, Karwan-e-Hayat and Karachi Psychiatric Hospital: 25 with ARMS for psychosis and 25 participants who were not ARMS, according to scores on Schizophrenia Proneness Inventory-Adult (SPI-A). All of the participants then responded to self-report questionnaire on Interpersonal Sensitivity Measure.

Results

Results showed that the group with ARMS had a significantly higher interpersonal sensitivity on average (112.5) as compared to healthy individuals (91.8). Results show significant difference in both of the groups (t = –5.049; P < .0001) indicating that interpersonal sensitivity in people with ARMS was relatively high compared to those who were not at risk.

Conclusion

This study suggests that being ‘hypersensitive’ to interpersonal interactions is a psychological feature of the potentially prodromal phase of psychosis. Addressing difficulties in interpersonal relationships and offering early psychotherapeutic interventions can be beneficial, not only in averting serious illness, but preventing loss to individual and national productivity.
