Binge drinking alcohol and circadian misalignment in night shift nurses is associated with decreased resiliency to COVID-19 infection

Background: Nurses and other first responders are at high risk of exposure to the SARS-CoV2 virus, and many have developed severe COVID-19 infection. A better understanding of the factors that increase the risk of infection after exposure to the virus could help to address this. Although several risk factors such as obesity, diabetes, and hypertension have been associated with an increased risk of infection, many first responders develop severe COVID-19 without established risk factors. As inflammation and cytokine storm are the primary mechanisms in severe COVID-19, other factors that promote an inflammatory state could increase the risk of COVID-19 in exposed individuals. Alcohol misuse and shift work with subsequent misaligned circadian rhythms are known to promote a pro-inflammatory state and thus could increase susceptibility to COVID-19. To test this hypothesis, we conducted a prospective, cross-sectional observational survey-based study in nurses using the American Nursing Association network. Method(s): We used validated structured questionnaires to assess alcohol consumption (the Alcohol Use Disorders Identification Test) and circadian typology or chronotype (the Munich Chronotype Questionnaire Shift -MCTQ-Shift). Result(s): By latent class analysis (LCA), high-risk features of alcohol misuse were associated with a later chronotype, and binge drinking was greater in night shift workers. The night shift was associated with more than double the odds of COVID-19 infection of the standard shift (OR 2.67, 95% CI: 1.18 to 6.07). Binge drinkers had twice the odds of COVID-19 infection of those with low-risk features by LCA (OR: 2.08, 95% CI: 0.75 to 5.79). Conclusion(s): Working night shifts or binge drinking may be risk factors for COVID-19 infection among nurses. Understanding the mechanisms underlying these risk factors could help to mitigate the impact of COVID-19 on our at-risk healthcare workforce.Copyright © 2023 The Authors.

Lipase Elevation in Patients With COVID-19.

INTRODUCTION: Although coronavirus disease (COVID-19) has been associated with gastrointestinal manifestations, its effect on the pancreas remains unclear. We aimed to assess the frequency and characteristics of hyperlipasemia in patients with COVID-19. METHODS: A retrospective cohort study of hospitalized patients across 6 US centers with COVID-19. RESULTS: Of 71 patients, 9 (12.1%) developed hyperlipasemia, with 2 (2.8%) greater than 3 times upper limit of normal. No patient developed acute pancreatitis. Hyperlipasemia was not associated with poor outcomes or symptoms. DISCUSSION: Although a mild elevation in serum lipase was observed in some patients with COVID-19, clinical acute pancreatitis was not seen.

Development of an Online Learning Module on Gastroenterology Issues in Global Health

Introduction: Global health (GH) education is expanding and 23.1% of US medical students acquire international health experience prior to postgraduate training. Digestive diseases carry a high global burden. However, few GH programs and professional societies consider the inclusion of gastroenterology into their standard curriculum. In addition, travel restrictions during the COVID-19 pandemic have brought traditional GH rotations to a halt and spurred new educational approaches. Our goal is to develop a comprehensive online learning module on gastroenterology issues in GH for medical students undertaking GH electives. Method(s): A team of faculty and residents was convened between the Center for Community and Global Health and the Division of Gastroenterology. GH curricula across institutions and core competencies across 2 professional societies were examined via literature review. A survey was conducted among 2nd (MS2) and 3rd year medical students (MS3) interested in GH to assess attitudes toward GI-related issues in GH curriculum. An online learning module was developed consisting of 10, video-based lessons each addressing specific GH competencies (Figure 1). Result(s): In total, 41% (28/69) of MS2 and MS3 interested in GH responded to the survey, with a similar distribution of MS2 (13/28) and MS3 (15/28). Nearly all (92.8%) reported that learning GI conditions in a GH curriculum is moderately or very important (Table 1). A majority (78.5%) also reported feeling at least somewhat anxious or more about managing GI conditions during GH electives. Few medical students reported feeling moderately or extremely prepared to identify risk factors for GI conditions in different settings (21.5%) and to define approaches to therapy in resource-limited settings (14.3%). Interestingly, a majority (71.4%) reported feeling not at all prepared or slightly prepared to deliver cost-effective care to challenging populations. Conclusion(s): Our survey responses demonstrated an unmet need for GI-related training and cost-conscious care in the GH curriculum. Developing an online learning module on GI conditions to supplement GH curriculum may be useful and feasible. A randomized controlled trial is underway to examine the effect of this online learning module on medical student knowledge and preparedness to address GI conditions in GH electives.

Left atrial stiffness and strain are novel indices of left ventricular diastolic function in children: validation followed by application in multisystem inflammatory syndrome in children due to COVID-19.

AIMS: We hypothesized left atrial (LA) stiffness may serve as a surrogate marker in children to differentiate elevated pulmonary capillary wedge pressure (PCWP) from normal and help detect diastolic dysfunction in myocardial injury due to multisystem inflammatory syndrome in children (MIS-C). METHODS AND RESULTS: We validated LA stiffness in 76 patients (median age 10.5 years), 33 had normal PCWP (<12 mmHg) and 43 had elevated PCWP (≥12 mmHg). LA stiffness was applied to 42 MIS-C patients [28 with myocardial injury (+) and 14 without myocardial injury (-)], defined by serum biomarkers. The validation group consisted of a group with and without cardiomyopathies, whose PCWP values ranged from normal to severely elevated. Peak LA strain was measured by speckle-tracking and E/e' from apical four chamber views. Noninvasive LA stiffness was calculated as: LAStiffness=E/e'LAPeakStrain (%-1). Patients with elevated PCWP showed significantly elevated LA stiffness [median 0.71%-1 vs. 0.17%-1, P < 0.001]. Elevated PCWP group showed significantly decreased LA strain (median: 15.0% vs. 38.2%, P < 0.001). Receiver operator characteristic (ROC) curve for LA stiffness yielded an area under the curve (AUC) of 0.88 and cutoff value of 0.27%-1. In MIS-C group, ROC curve yielded an AUC of 0.79 and cutoff value of 0.29%-1 for identifying myocardial injury. CONCLUSION: In children with elevated PCWP, LA stiffness was significantly increased. When applied to children with MIS-C, LA stiffness classified myocardial injury accurately. LA stiffness and strain may serve as noninvasive markers of diastolic function in the pediatric population.

Structure-Based Identification of Naphthoquinones and Derivatives as Novel Inhibitors of Main Protease Mpro and Papain-like Protease PLpro of SARS-CoV-2.

The worldwide COVID-19 pandemic caused by the coronavirus SARS-CoV-2 urgently demands novel direct antiviral treatments. The main protease (Mpro) and papain-like protease (PLpro) are attractive drug targets among coronaviruses due to their essential role in processing the polyproteins translated from the viral RNA. In this study, we virtually screened 688 naphthoquinoidal compounds and derivatives against Mpro of SARS-CoV-2. Twenty-four derivatives were selected and evaluated in biochemical assays against Mpro using a novel fluorogenic substrate. In parallel, these compounds were also assayed with SARS-CoV-2 PLpro. Four compounds inhibited Mpro with half-maximal inhibitory concentration (IC50) values between 0.41 µM and 9.0 µM. In addition, three compounds inhibited PLpro with IC50 ranging from 1.9 µM to 3.3 µM. To verify the specificity of Mpro and PLpro inhibitors, our experiments included an assessment of common causes of false positives such as aggregation, high compound fluorescence, and inhibition by enzyme oxidation. Altogether, we confirmed novel classes of specific Mpro and PLpro inhibitors. Molecular dynamics simulations suggest stable binding modes for Mpro inhibitors with frequent interactions with residues in the S1 and S2 pockets of the active site. For two PLpro inhibitors, interactions occur in the S3 and S4 pockets. In summary, our structure-based computational and biochemical approach identified novel naphthoquinonal scaffolds that can be further explored as SARS-CoV-2 antivirals.

CoVID-19 Vaccine Efficacy in Heart Transplant Recipients, a Single Center Experience

Purpose: Transplant recipients have worse CoVID-19 survival compared to the general population, and thus are recommended to be vaccinated and boosted. Determinants of vaccination efficacy have not been well studied in heart transplant patients. Method(s): This was a prospective study of heart transplant recipients vaccinated against SARS-CoV-2 with one of the 2-dose mRNA vaccine series. Antibodies (Ab) were quantified by anti-Spike ELISA pre- and post-vaccination. Clinical data was extracted from electronic medical records. Differences in Ab detection and timing of Abs were assessed for statistical significance using Fisher's exact tests for categorical variables and t-tests for continuous variables. Result(s): Of the total 54 participants recruited from Jan 2021 to present, 6 patients were Ab positive prior to vaccination and 11 did not provide a pre-vaccination sample but were Ab positive post-vaccination. Almost half of participants (48%, n=26) received a booster 3rd dose. The mean age at vaccination was 58 +/- 11, 20% (n=11) were female, 70% (n=38) were Caucasian, and median time since transplant was 4 years (interquartile range: 2-11 years). Of the 37 Ab-negative individuals enrolled, none developed detectable Abs after a single vaccine dose and only 9 (24%) developed Abs after the 2nd vaccine dose. Interestingly in this small group, 6/9 (66%) of participants had delayed seroconversion of approximately 3 months. Unexpectedly, hyperlipidemia was positively associated with a detectable antibody response (p = 0.05) after the 2nd dose. There was also a trend toward higher age (p=0.06) and BMI (p=0.08) being associated with lack of response to the 2-dose series. Importantly, of the 28 patients who had no Ab response to the 2-dose vaccination regimen, 11/17 (65%) became Ab positive after the booster, increasing the vaccine response rate in this pre-vaccine Ab-negative group to 20/37 (54%). Looking at the total cohort of 54 participants, the overall positivity rate regardless of antigen sources (i.e., including those previously infected or for whom no pre-vaccine sample is available) is 68.5% (37/54) with a trend suggesting that absence of Ab response may be associated with prednisone treatment (p=0.06). Conclusion(s): Heart transplant recipients exhibit a low response rate to the initial 2-dose mRNA vaccines (24%), but the 3rd dose induces a response in the majority of those who failed to respond to the 2-dose series increasing overall response to over 50%. Similar to observations in the general public, non-response tended to be associated with older age and higher BMI. However, further/larger studies are needed to identify key determinants of vaccine efficacy in this population to guide management.

An online survey of UK women's attitudes to having children, the age they want children and the effect of the COVID-19 pandemic.

STUDY QUESTION: What are women's views on having children, including the age they want to have them and other influences such as the coronavirus disease 2019 (COVID-19) pandemic? SUMMARY ANSWER: Women's views on having children, at their preferred age of 30 years, included their maternal urge and concerns about their biological clock and stability, while 19% said COVID-19 had affected their views. WHAT IS KNOWN ALREADY: Women globally are delaying the birth of their first child, with the average age of first birth approaching 32 years in some countries. The average age women have their first child in the UK is 30.7 years and over 50% of women aged 30 years are childless. The fertility rate stands at 1.3 in several European Union countries. Some people are not having their desired family size or are childless by circumstance. It is essential to understand people's attitudes to having children in different countries to identify trends so we can develop educational resources in an age-appropriate manner. STUDY DESIGN, SIZE, DURATION: We conducted an anonymous, online survey of multiple choice and open-ended questions. The survey was live for 32 days from 15 May 2020 to 16 June 2020 and was promoted using social media. PARTICIPANTS/MATERIALS, SETTING, METHODS: A total of 887 women from 44 countries participated in the survey. After filtering out women who did not consent, gave blank or incomplete responses, and those not in the UK, 411 responses remained. From the data, three areas of questioning were analysed: their views on having children, the ideal age they want to have children and the effects of the COVID-19 pandemic. Qualitative data were analysed by thematic analysis. MAIN RESULTS AND THE ROLE OF CHANCE: The average age (±SD) of the women who completed the survey was 32.2 years (±5.9), and they were mainly heterosexual (90.8%) and 84.8% had a university education. One-third of women were married/in a civil partnership (37.7%) and 36.0% were cohabitating. In relation to their views on having children, the main themes identified were: the maternal urge, the ticking of the biological clock, why did no one teach us this?, the need for stability and balance in their life, pressure to start a family and considering other ways to have a family. When asked 'In an ideal world, at what age approximately would you like to have had or have children?' a normal distribution was observed with a mean age of 29.9 (±3.3) years. When asked 'What factors have led you to decide on that particular age?' the most frequent choice was 'I am developing my career'. Three themes emerged from the qualitative question on why they chose that age: the need for stability and balance in their life, the importance of finding the right time and life experiences. The majority of women felt that the COVID-19 pandemic had not affected their decision to have children (72.3%), but 19.1% said it had. The qualitative comments showed they had concerns about instability in their life, such as finances and careers, and delays in fertility treatment. LIMITATIONS, REASONS FOR CAUTION: The survey was promoted on social media only and the women who answered the survey were highly educated. WIDER IMPLICATIONS OF THE FINDINGS: The women surveyed ideally want children at age 30 years but there are obstacles in their way, such as the need to develop their career. Global tailored fertility education is essential to ensure people make informed reproductive choices. In addition, it is essential for supportive working environments and affordable childcare to be in place in every country.

Enzymatic Laser-Induced Graphene Biosensor for Electrochemical Sensing of the Herbicide Glyphosate.

Glyphosate is a globally applied herbicide yet it has been relatively undetectable in-field samples outside of gold-standard techniques. Its presumed nontoxicity toward humans has been contested by the International Agency for Research on Cancer, while it has been detected in farmers' urine, surface waters and crop residues. Rapid, on-site detection of glyphosate is hindered by lack of field-deployable and easy-to-use sensors that circumvent sample transportation to limited laboratories that possess the equipment needed for detection. Herein, the flavoenzyme, glycine oxidase, immobilized on platinum-decorated laser-induced graphene (LIG) is used for selective detection of glyphosate as it is a substrate for GlyOx. The LIG platform provides a scaffold for enzyme attachment while maintaining the electronic and surface properties of graphene. The sensor exhibits a linear range of 10-260 µ m, detection limit of 3.03 µ m, and sensitivity of 0.991 nA µ m -1. The sensor shows minimal interference from the commonly used herbicides and insecticides: atrazine, 2,4-dichlorophenoxyacetic acid, dicamba, parathion-methyl, paraoxon-methyl, malathion, chlorpyrifos, thiamethoxam, clothianidin, and imidacloprid. Sensor function is further tested in complex river water and crop residue fluids, which validate this platform as a scalable, direct-write, and selective method of glyphosate detection for herbicide mapping and food analysis.

Tailoring Our Approach in Response to the SARS-CoV-2 Pandemic and Transcending Science Outreach Modalities for Native American Students in a Cancer Research Education Program.

In response to the SARS-CoV-2 pandemic, a cancer research education program at the University of Nebraska Medical Center designed for Native American middle school, high school and undergraduate students adapted activities to be delivered online. There are considerable challenges to adapting in-person science programming to online delivery that can impact overall effectiveness. These challenges are further exacerbated when the cognate student population also faces significant disparities in health, wealth, and educational outcomes. We encountered both disadvantages and advantages in transitioning programming to online virtual formats. Challenges faced in delivering our programming during the pandemic included varied online accessibility, peripheral stressors, and disconnection to places and people. Despite these challenges, we found several benefits in remote delivery, some of which have alleviated barriers to program participation for Native American students. Some successes achieved by transitioning to fully remote programming included increased program reach, sustainability, and cultural relevancy. In this overview of the implementation of four online programs at the middle school, high school, and undergraduate levels, we highlight the challenges and successes experienced. Through this program description, we aim to provide insight into potential strategies to improve program delivery designed for Native American students during the SARS-CoV-2 pandemic and beyond.

Clinical characteristics and outcomes of COVID-19 patients in a tertiary hospital in Baguio City, Philippines.

OBJECTIVE: Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), primarily targets the respiratory system. This study describes the characteristics associated with mortality among patients infected with SARS-CoV-2 at a single hospital in Baguio City, Philippines. METHODS: We reviewed medical records (including history, laboratory results and treatment regimen) of 280 confirmed COVID-19 patients admitted to a single hospital during March-October 2020. Clinical characteristics and outcomes (frequency and type of complication, recovery rate and mortality) were evaluated. Multiple logistic regression was used to analyse factors associated with mortality. RESULTS: The mean age of COVID-19 patients was 48.4 years and the female-to-male ratio was 1.8:1. Hypertension, cardiovascular disease (CVD) and diabetes were the most frequent comorbidities reported. Common presenting symptoms were respiratory and constitutional, with 41% of patients not reporting symptoms on admission. Patients with moderate, severe and critical disease comprised 45%, 8% and 4%, respectively. A total of 15% had complications, health care-associated pneumonia being the most frequent complication. The recovery rate was 95%; 5% of patients died, with multiorgan failure being the most common cause. The presence of CVD, chronic kidney disease, prolonged prothrombin time and elevated lactate dehydrogenase (LDH) were associated with mortality. DISCUSSION: Most COVID-19 patients in our population had asymptomatic to moderate disease on admission. Mortality from COVID-19 was associated with having CVD, chronic kidney disease, elevated LDH and prolonged prothrombin time. Based on these results, we emphasize that people should take all necessary precautions to avoid infection with SARS-CoV-2.

Structure-based identification of naphthoquinones and derivatives as novel inhibitors of main protease Mpro and papain-like protease PLpro of SARS-CoV-2 (preprint)

The worldwide COVID-19 pandemic caused by the coronavirus SARS-CoV-2 urgently demands novel direct antiviral treatments. The main protease (Mpro) and papain-like protease (PLpro) are attractive drug targets among coronaviruses due to their essential role in processing the polyproteins translated from the viral RNA. In the present work, we virtually screened 688 naphthoquinoidal compounds and derivatives against Mpro of SARS-CoV-2. Twenty-four derivatives were selected and evaluated in biochemical assays against Mpro using a novel fluorogenic substrate. In parallel, these compounds were also assayed with SARS-CoV-2 PLpro. Four compounds inhibited Mpro with half-maximal inhibitory concentration (IC50) values between 0.41 M and 66 M. In addition, eight compounds inhibited PLpro with IC50 ranging from 1.7 M to 46 M. Molecular dynamics simulations suggest stable binding modes for Mpro inhibitors with frequent interactions with residues in the S1 and S2 pockets of the active site. For two PLpro inhibitors, interactions occur in the S3 and S4 pockets. In summary, our structure-based computational and biochemical approach identified novel naphthoquinonal scaffolds that can be further explored as SARS-CoV-2 antivirals.

How Do Presenting Symptoms and Outcomes Differ by Race/Ethnicity Among Hospitalized Patients With Coronavirus Disease 2019 Infection? Experience in Massachusetts.

BACKGROUND: Population-based literature suggests severe acute respiratory syndrome coronavirus 2 infection may disproportionately affect racial/ethnic minorities; however, patient-level observations of hospitalization outcomes by race/ethnicity are limited. Our aim in this study was to characterize coronavirus disease 2019 (COVID-19)-associated morbidity and in-hospital mortality by race/ethnicity. METHODS: This was a retrospective analysis of 9 Massachusetts hospitals including all consecutive adult patients hospitalized with laboratory-confirmed COVID-19. Measured outcomes were assessed and compared by patient-reported race/ethnicity, classified as white, black, Latinx, Asian, or other. Student t test, Fischer exact test, and multivariable regression analyses were performed. RESULTS: A total of 379 patients (aged 62.9 ± 16.5 years; 55.7% men) with confirmed COVID-19 were included (49.9% white, 13.7% black, 29.8% Latinx, 3.7% Asian), of which 376 (99.2%) were insured (34.3% private, 41.2% public, 23.8% public with supplement). Latinx patients were younger, had fewer cardiopulmonary disorders, were more likely to be obese, more frequently reported fever and myalgia, and had lower D-dimer levels compared with white patients (P < .05). On multivariable analysis controlling for age, gender, obesity, cardiopulmonary comorbidities, hypertension, and diabetes, no significant differences in in-hospital mortality, intensive care unit admission, or mechanical ventilation by race/ethnicity were found. Diabetes was a significant predictor for mechanical ventilation (odds ratio [OR], 1.89; 95% confidence interval [CI], 1.11-3.23), while older age was a predictor of in-hospital mortality (OR, 4.18; 95% CI, 1.94-9.04). CONCLUSIONS: In this multicenter cohort of hospitalized COVID-19 patients in the largest health system in Massachusetts, there was no association between race/ethnicity and clinically relevant hospitalization outcomes, including in-hospital mortality, after controlling for key demographic/clinical characteristics. These findings serve to refute suggestions that certain races/ethnicities may be biologically predisposed to poorer COVID-19 outcomes.

Exploring the Temporal Dynamics of County-Level Vulnerability Factors on COVID-19 Outcomes (preprint)

As the outbreak of COVID-19 has become a severe worldwide pandemic, every country fights against the spread of this deadly disease with incredible efforts. There are numerous researches along with every conceivable dimension for COVID-19. Among these researches, different demographic and contextual factors of populations and communities also play an essential role in providing more information for decision-makers. This paper mainly utilizes existing data on county contextual factors at the United States county-level to develop a model that can capture the dynamic trajectory of COVID-19 (i.e., cases) and its impacts across the United States. Moreover, our methods applied to contextual data achieves better results compared with existing measures of vulnerability.

Skewed Cytokine Responses Rather Than the Magnitude of the Cytokine Storm May Drive Cardiac Dysfunction in Multisystem Inflammatory Syndrome in Children.

Background Cardiac dysfunction is a prominent feature of multisystem inflammatory syndrome in children (MIS-C), yet the etiology is poorly understood. We determined whether dysfunction is global or regional, and whether it is associated with the cytokine milieu, microangiopathy, or severity of shock. Methods and Results We analyzed echocardiographic parameters of myocardial deformation and compared global and segmental left ventricular strain between 43 cases with MIS-C ≤18 years old and 40 controls. Primary outcomes included left ventricular global longitudinal strain, right ventricular free wall strain), and left atrial strain. We evaluated relationships between strain and profiles of 10 proinflammatory cytokines, microangiopathic features (soluble C5b9), and vasoactive-inotropic requirements. Compared with controls, cases with MIS-C had significant impairments in all parameters of systolic and diastolic function. 65% of cases with MIS-C had abnormal left ventricular function (|global longitudinal strain|<17%), although elevations of cytokines were modest. All left ventricular segments were involved, without apical or basal dominance to suggest acute stress cardiomyopathy. Worse global longitudinal strain correlated with higher ratios of interleukin-6 (ρ -0.43) and interleukin-8 (ρ -0.43) to total hypercytokinemia, but not absolute levels of interleukin-6 or interleukin-8, or total hypercytokinemia. Similarly, worse right ventricular free wall strain correlated with higher relative interleukin-8 expression (ρ -0.59). There were no significant associations between function and microangiopathy or vasoactive-inotropic requirements. Conclusions Myocardial function is globally decreased in MIS-C and not explained by acute stress cardiomyopathy. Cardiac dysfunction may be driven by the relative skew of the immune response toward interleukin-6 and interleukin-8 pathways, more so than degree of hyperinflammation, refining the current paradigm of myocardial involvement in MIS-C.

[Experiences of (care) professionals during a COVID-19 outbreak and results of serological tests in the staff of a heavily affected nursing home.] / Ervaringen van (zorg)medewerkers tijdens een COVID-19 uitbraak en resultaten van serologische testen bij personeel in een zwaar getroffen verpleeghuis.

Despite compliance with national (RIVM) guidelines, nursing home Mariënburght (the Netherlands) was severely affected during the first COVID-19 wave: 68 (68%) of the residents were infected. This resulted in a large emotional impact on the (nursing) staff. This study aims to describe the experiences of (nursing) staff, as well as the results of serological tests on COVID-19 that have been administered to professionals. All professionals (n=281) were invited for group interviews to share their experiences concerning the COVID-19 outbreak and for a serological test for COVID-19. The 29 professionals participating in the group interviews mentioned negative and positive experiences about their fear and anxiety, the changed care for residents, the team spirit, the use of personal protective equipment and the testing policy. Out of 240 professionals who underwent the serological test and completed a questionnaire, 94 professionals (39%) had COVID-19 antibodies. In this group, 18 professionals (19%) indicated not having experienced any (physical) complaints related to COVID. Insight into the experiences of professionals resulted in essential learning points, in particular the importance of clear communication with and emotional support for staff. This study also reveals that many professionals of nursing home Mariënburght were affected by COVID-19. An important finding is the high percentage of asymptomatic employees (19% of 94 infected). Our results contributed to changed national testing policies and adapted recommendations in the use of personal protective equipment in nursing homes.

High Prevalence of Gastrointestinal Manifestations of COVID-19 Infection in Hospitalized Patients With Cancer.

BACKGROUND AND AIM: Gastrointestinal (GI) symptoms have been reported with SARS-CoV-2 infection, but data on the prevalence and severity of GI symptoms in patients with cancer are limited. We sought to characterize the GI manifestations of coronavirus disease-19 (COVID-19) in oncology patients. MATERIALS AND METHODS: We performed a multicenter cohort study of adult patients hospitalized with COVID-19 in 9 Massachusetts medical centers and identified those with an active malignancy. We evaluated the prevalence and severity of GI symptoms among hospitalized COVID-19 patients with cancer. RESULTS: Of 395 hospitalized patients with COVID-19, 36 (9%) had an active malignancy. Of the 36 cancer patients, 23 (63%) reported ≥1 new GI symptom. The most prevalent symptoms were anorexia (12, 52%), diarrhea (9, 39%), and vomiting (8, 35%). GI symptoms were the initial symptom in 4/36 (11%) patients, were the predominant symptom in 5/36 (14%) patients, and were severe in 4/23 (17%) patients. Four of 5 patients with GI symptoms at presentation reported concurrent fever; notably 1 patient had no fever or respiratory symptoms. Twelve (33%) patients had elevations in liver transaminases at presentation; patients with elevated transaminases were more likely to have associated GI symptoms (83% vs. 54%, P=0.04). CONCLUSIONS: Acute GI symptoms associated with COVID-19 are highly prevalent in hospitalized cancer patients and can occur as a presenting symptom without respiratory symptoms. Symptoms are severe in a small subset of patients.
