COVID-19 status quo: Emphasis on gastrointestinal and liver manifestations.

The coronavirus disease 2019 (COVID-19) has caused one of the worst public health crises in modern history. Even though severe acute respiratory syndrome coronavirus 2 primarily affects the respiratory tract, gastrointestinal manifestations are well described in literature. This review will discuss the epidemiology, virology, manifestations, immunosuppressant states, and lessons learned from COVID-19. Observations: At the time of writing, COVID-19 had infected more than 111 million people and caused over 2.5 million deaths worldwide. Multiple medical comorbidities including obesity, pre-existing liver condition and the use of proton pump inhibitor have been described as risk factor for severe COVID-19. COVID-19 most frequently causes diarrhea (12.4%), nausea/vomiting (9%) and elevation in liver enzymes (15%-20%). The current data does not suggest that patients on immunomodulators have a significantly increased risk of mortality from COVID-19. The current guidelines from American Gastroenterological Association and American Association for the Study of Liver Diseases do not recommend pre-emptive changes in patients on immunosuppression if the patients have not been infected with COVID-19. Conclusions and relevance: The COVID-19 pandemic has prompted a change in structure and shape of gastroenterology departmental activities. Endoscopy should be performed only when necessary and with strict protective measures. Online consultations in the form of telehealth services and home drug deliveries have revolutionized the field.

Combining International Survey Datasets to Identify Indicators of Stress during the COVID-19 Pandemic: A Machine Learning Approach to Improve Generalization

The scale and duration of the worldwide SARS-COVID-2 virus-related quarantine measures presented the global scientific community with a unique opportunity to study the accompanying psychological stress. Since March 2020, numerous publications have reported similar findings from diverse international studies on psychological stress, depression, and anxiety, which have increased during this pandemic. However, there remains a gap in interpreting the results from one country to another despite the global rise in mental health problems. The objective of our study was to identify global indicators of pandemic-related stress that traverse geographic and cultural boundaries. We amalgamated data from two independent global surveys across twelve countries and spanning four continents collected during the first wave of the mandated public health measures aimed at mitigating COVID-19. We applied machine learning (ML) modelling to these data, and the results revealed a significant positive correlation between PSS-10 scores and gender, relationship status, and groups. Confinement, fear of contagion, social isolation, financial hardship, etc., may be some reasons reported being the cause of the drastic increase in mental health problems worldwide. The decline of the typical protective factors (e.g., sleep, exercise, meditation) may have amplified existing vulnerabilities/co-morbidities (e.g., psychiatric history, age, gender). Our results further show that ML is an apropos tool to elucidate the underlying predictive factors in large, complex, heterogeneous datasets without invalidating the model assumptions. We believe our model provides clinicians, researchers, and decision-makers with evidence to investigate the moderators and mediators of stress and introduce novel interventions to mitigate the long-term effects of the COVID-19 pandemic.

Impact of the SARS-CoV-2 pandemic on turnover time and revenue in the endoscopy unit: single-center experience.

Background and study aims The SARS-CoV-2 pandemic heavily impacted the New York metro area causing most institutions to either reduce case volume or fully close remaining open units incorporated specific guidelines for procedures lockdown potentially leading to a greater turn-over time. We analyzed the quantitative and financial impact of this lost time on our tertiary care center's endoscopy unit. Patients and methods This single-center, retrospective study included demographics, procedure details and turn-over times (TOT) from all endoscopic procedures between December 1, 2019 to June 30, 2020. Cases were categorized as pre-COVID-19 group from December 1, 2019 to March 15, 2020 and during COVID-19 (lockdown) group from March 16, 2020 to June 30, 2020. The financial impact was assessed using national averages for reimbursement of outpatient endoscopic procedures provided by Center for Medicare and Medicaid Services. Results A total of 3622 procedures were performed during the study period: 2297 in the pre-COVID-19 period, 1325 in the COVID-19 period, representing a 42.32 % decrease. In the COVID-19 lockdown group, there was a significant increase in TOT in both the general endoscopy cases (18.11 minutes, P  = 0.000) and advanced endoscopy cases (17.7 minutes, P  = 0.000). The 42.3 % decrease in volume equated to at least $1.6 million USD in lost revenue during the lockdown. Conclusions COVID-19 pandemic led to an increase in TOT with overall reduced procedure volume and a negative effect on revenue. Providing continued endoscopic management during a pandemic avoids delays in reopening the endoscopy unit and hampers the post-pandemic surge of delayed cases and its financial impact.
