Characteristics and rates of infection by HIV in people receiving non-occupational post-exposure prophylaxis (nPEP) against HIV.

INTRODUCTION/OBJECTIVES: The use of non-occupational post-exposure prophylaxis (nPEP) emerges as a strategic intervention to reduce HIV infection risk following sexual encounters in our setting. Notwithstanding, there is a scarcity of contemporary data regarding adherence to this treatment, its effectiveness and tolerance. Our study aims to delve into these factors among individuals who have resorted to nPEP after high-risk sexual encounters. METHODS: We conducted a retrospective observational study of cases administered nPEP for HIV from 1 January 2018 to 31 December 2021 at a tertiary hospital in Madrid. The study included all adults over 18 years who sought care at the emergency department of the Fundación Jiménez Díaz Hospital following a risky sexual encounter and were subsequently recommended HIV nPEP treatment. RESULTS: 878 individuals received nPEP for HIV and underwent initial serological tests. Of these, 621 had comprehensive follow-ups. The prescribed regimen for all was raltegravir (RAL) 1200 mg combined with tenofovir/emtricitabine (TDF/FTC) 245/200 mg daily for 28 days. The study revealed a 1.1% rate (n=10) of previously undetected infection and a 0.16% (n=1) failure rate of nPEP. Regarding regimen tolerability, 5.6% (n=35) experienced symptoms linked to the treatment, yet none necessitated discontinuation of the regimen. On the contrary, six per cent (n=53) reported symptoms consistent with an STI during one of the medical visits; specifically, 4.4% had urethritis, and 1.6% had proctitis. CONCLUSION: nPEP with RAL/TDF/FTC demonstrates high efficacy and safety, contingent on proper adherence. There is an observed increase in STI prevalence in this cohort, with nearly half of the participants not engaging in appropriate follow-up after initiating nPEP.

Miniaturized flexible micro-tube plasma ionization source for the effective ionization of non-easily ionizable pesticides in food with liquid chromatography/mass spectrometry.

In this article, we have studied the potential of flexible microtube plasma (FµTP) as ionization source for the liquid chromatography high-resolution mass spectrometry detection of non-easily ionizable pesticides (viz. nonpolar and non-ionizable by acid/basic moieties). Phthalimide-related compounds such as dicofol, dinocap, o-phenylphenol, captan, captafol, folpet and their metabolites were studied. Dielectric barrier discharge ionization (DBDI) was examined using two electrode configurations, including the miniaturized one based on a single high-voltage (HV) electrode and a virtual ground electrode configuration (FµTP), and also the two-ring electrode DBDI configuration. Different ionization pathways were observed to ionize these challenging, non-easily ionizable nonpolar compounds, involving nucleophilic substitutions and proton abstraction, with subtle differences in the spectra obtained compared with APCI. An average sensitivity increase of 5-fold was attained compared with the standard APCI source. In addition, more tolerance with matrix effects was observed in both DBDI sources. The importance of the data reported is not just limited to the sensitivity enhancement compared to APCI, but, more notably, to the ability to effectively ionize nonpolar, late-eluting (in reverse-phase chromatography) non-ionizable compounds. Besides o-phenylphenol ([M - H]-), all the parent species were efficiently ionized through different mechanisms involving bond cleavages through the effect of plasma reagent species or its combination with thermal degradation and subsequent ionization. This tool can be used to figure out overlooked nonpolar compounds in different environmental samples of societal interest through non-target screening (NTS) strategies.

Discovery of circulating miRNAs as biomarkers of chronic Chagas heart disease via a small RNA-Seq approach.

Chagas disease affects approximately 7 million people worldwide in Latin America and is a neglected tropical disease. Twenty to thirty percent of chronically infected patients develop chronic Chagas cardiomyopathy decades after acute infection. Identifying biomarkers of Chagas disease progression is necessary to develop better therapeutic and preventive strategies. Circulating microRNAs are increasingly reliable biomarkers of disease and therapeutic targets. To identify new circulating microRNAs for Chagas disease, we performed exploratory small RNA sequencing from the plasma of patients and performed de novo miRNA prediction, identifying potential new microRNAs. The levels of the new microRNAs temporarily named miR-Contig-1519 and miR-Contig-3244 and microRNAs that are biomarkers for nonchagasic cardiomyopathies, such as miR-148a-3p and miR-224-5p, were validated by quantitative reverse transcription. We found a specific circulating microRNA signature defined by low miR-Contig-3244, miR-Contig-1519, and miR-148a-3 levels but high miR-224-5p levels for patients with chronic Chagas disease. Finally, we predicted in silico that these altered circulating microRNAs could affect the expression of target genes involved in different cellular pathways and biological processes, which we will explore in the future.

How different countries respond to adverse events whilst patients' rights are protected.

Patient safety is high on the policy agenda internationally. Learning from safety incidents is a core component in achieving the important goal of increasing patient safety. This study explores the legal frameworks in the countries to promote reporting, disclosure, and supporting healthcare professionals (HCPs) involved in safety incidents. A cross-sectional online survey was conducted to ascertain an overview of the legal frameworks at national level, as well as relevant policies. ERNST (The European Researchers' Network Working on Second Victims) group peer-reviewed data collected from countries was performed to validate information. Information from 27 countries was collected and analyzed, giving a response rate of 60%. A reporting system for patient safety incidents was in place in 85.2% (N = 23) of countries surveyed, though few (37%, N = 10) were focused on systems-learning. In about half of the countries (48.1%, N = 13) open disclosure depends on the initiative of HCPs. The tort liability system was common in most countries. No-fault compensation schemes and alternative forms of redress were less common. Support for HCPs involved in patient safety incidents was extremely limited, with just 11.1% (N = 3) of participating countries reporting that supports were available in all healthcare institutions. Despite progress in the patient safety movement worldwide, the findings suggest that there are considerable differences in the approach to the reporting and disclosure of patient safety incidents. Additionally, models of compensation vary limiting patients' access to redress. Finally, the results highlight the need for comprehensive support for HCPs involved in safety incidents.

The Impact of Frailty, Oropharyngeal Dysphagia and Malnutrition on Mortality in Older Patients Hospitalized for Covid-19.

COVID-19 hospital mortality is higher among older patients through as yet little-known factors. We aimed to assess the effect of frailty (FR), oropharyngeal dysphagia (OD) and malnutrition (MN) on mortality in hospitalized COVID-19 older patients. Prospective cohort study of older patients (>70 years) with COVID-19 admitted to a general hospital from April 2020 to January 2021. Patients were evaluated on admission, discharge and at 1- and 3-months follow up. FR was assessed with FRAIL-VIG, OD with Volume-Viscosity Swallowing Test and MN with GLIM criteria. Clinical characteristics and outcomes, including intra-hospital, 1- and 3-month mortality, were analyzed. 258 patients were included (82.5±7.6 years; 58.9% women); 66.7% had FR (mild 28.7%, moderate 27.1% and severe 10.9%); 65.4%, OD and 50.6%, MN. OD prevalence increased from non-FR patients through the severity levels of FR: mild, moderate and severe (29.8%, 71.6%, 90.0%, 96.2%; p<0.0001, respectively), but not that of MN (50.6%, 47.1%, 52.5%, 56.0%). Mortality over the whole study significantly increased across FR categories (9.3% non-FR; 23.0% mild; 35.7% moderate; 75.0% severe; p<.001). Functionality (Barthel pre-admission, HR=0.983, CI-95%:0.973-0.993; p=0.001), OD (HR=2.953, CI-95%:0.970-8.989; p=0.057) and MN (HR=4.279, CI-95%:1.658-11.049; p=0.003) were independent risk factors for intra-hospital mortality. FR, OD and MN are highly prevalent conditions in older patients hospitalized with COVID-19. Functionality, OD and MN were independent risk factors for intra-hospital mortality.

Key factors for effective implementation of healthcare workers support interventions after patient safety incidents in health organisations: a scoping review.

OBJECTIVES: This study aims to map and frame the main factors present in support interventions successfully implemented in health organisations in order to provide timely and adequate response to healthcare workers (HCWs) after patient safety incidents (PSIs). DESIGN: Scoping review guided by the six-stage approach proposed by Arksey and O'Malley and by PRISMA-ScR. DATA SOURCES: CINAHL, Cochrane Library, Embase, Epistemonikos, PsycINFO, PubMed, SciELO Citation Index, Scopus, Web of Science Core Collection, reference lists of the eligible articles, websites and a consultation group. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Empirical studies (original articles) were prioritised. We used the Mixed Methods Appraisal Tool Version 2018 to conduct a quality assessment of the eligible studies. DATA EXTRACTION AND SYNTHESIS: A total of 9766 records were retrieved (last update in November 2022). We assessed 156 articles for eligibility in the full-text screening. Of these, 29 earticles met the eligibility criteria. The articles were independently screened by two authors. In the case of disagreement, a third author was involved. The collected data were organised according to the Organisational factors, People, Environment, Recommendations from other Audies, Attributes of the support interventions. We used EndNote to import articles from the databases and Rayyan to support the screening of titles and abstracts. RESULTS: The existence of an organisational culture based on principles of trust and non-judgement, multidisciplinary action, leadership engagement and strong dissemination of the support programmes' were crucial factors for their effective implementation. Training should be provided for peer supporters and leaders to facilitate the response to HCWs' needs. Regular communication among the implementation team, allocation of protected time, funding and continuous monitoring are useful elements to the sustainability of the programmes. CONCLUSION: HCWs' well-being depends on an adequate implementation of a complex group of interrelated factors to support them after PSIs.

Developing a mobile health app for chronic illness management: Insights from focus groups.

Background: Mobile applications have the potential to assist patients and caregivers in managing chronic diseases, but current offerings are typically limited to a single disease or only focused on patients. A multifaceted app could expand the user base and provide more comprehensive support for patients who usually suffer from diverse chronic conditions at the same time and their caregivers. Objectives: This study aimed to design, develop, and evaluate a mobile application that could aid chronic patients and their caregivers in managing the range of chronic conditions. Methods: Focus group meetings were conducted with patients and caregivers to identify their needs, which were translated into app functionalities. The final version of the app was evaluated through a survey and analysis of the most used features. Results: Five focus group (FG) meetings were held, involving 39 patients and 22 caregivers. The app included medication aids, self-monitoring aids, activation reminders, messages for caregiver shifts, remote monitoring, medicine management, and informative videos. Testing by 65 patients revealed that medication reminders (96.8% positive responses), medicine information (96.8%), messages for caregiver shifts (90.3%), and ease of use (80.6%) were the most valued aspects. The most frequently used feature was the health data record check. Conclusions: A multifaceted mobile application can address the needs of a variety of chronic patients and their caregivers, while still being easy to use. The app's most used functionalities were aligned with the needs expressed in the FG, which reflects the success of this study and suggests that future research could benefit from incorporating similar user-centered design methodologies.

Social support for overcoming fear of contagion at the start of the COVID-19 pandemic. Cross-sectional study in Latin America.

Background: The psychological impact of the COVID-19 pandemic on healthcare professionals has been widely studied, along with different strategies to minimize it. However, professionals' assessment of the social support received and the factors that mitigated their fear of contagion have not been described. This study aimed to assess healthcare professionals' satisfaction with the social support and information received and their efforts to self-isolate to avoid infecting loved ones in Chile, Colombia, and Ecuador. Methods: A cross-sectional online survey, conducted from July to September 2020 in three Latin American countries, elicited healthcare professionals' satisfaction with social support from colleagues, their community, the media, and scientific societies; as well as the information received about the evolution of the pandemic and measures to avoid contagion. The EASE scale was used to measure acute stress. Results: Survey responses were received from 700 professionals. The response rate per country exceeded the estimated sample size except in the case of Colombia, which was 81.4%. In general, peer support was highly valued, though satisfaction was lower in high-risk units (p < 0.001). Those who directly assisted COVID-19 patients perceived the least community support (p = 0.023). Professionals from high-risk units (p = 0.013) and those who experienced greater acute stress (p = 0.05) assigned the lowest rating to the information offered by the centre on the pandemic. Men perceived more support from colleagues and better information from the centre than women (p < 0.05). Just 10.7% of professionals changed their residence during the pandemic, but those who worked in high-risk areas self-isolated more frequently (p = 0.026). Conclusion: In the early stages of the COVID-19 pandemic, healthcare professionals in Chile, Colombia, and Ecuador greatly valued the support received from their peers. Being infected with COVID-19, working in high-risk areas, experiencing higher self-reported acute stress, and having an infected co-worker were predictors for self-isolation to protect their relatives. These results point to the appropriateness of putting in place institutional resources based on peer support and specific communication strategies and action protocols to build resilience and responsiveness to future health crises.

Prevalence of Chagas disease in Latin American pregnant women in Madrid, Spain: A multicentre cross-sectional study from 2011 to 2016.

OBJECTIVE: The aim of this study is to assess Trypanosoma cruzi infection prevalence among pregnant migrants living in Madrid according to the country of origin and to assess screening coverage in this at-risk population. METHODS: Retrospective multicentre cross-sectional study conducted from January 2011 to December 2016 in eight Madrid hospitals. Each hospital reviewed their microbiology data records to assess the screening coverage and serological diagnosis in all pregnant women coming from endemic areas. RESULTS: From 2011 to 2016, 149,470 deliveries were attended at the eight hospitals, and 11,048 pregnant women were screened for Chagas disease. Most cases (93.5%) were in women from Bolivia, who also showed the highest prevalence (12.4%, 95% confidence interval: 9.9-15.0). Pooled prevalence amongst the screened women was 2.9% (95% CI: 1.8-4.1). Chagas disease screening coverage varied greatly between centres, with a pooled mean coverage of 47% (95% CI: 37%-57%; 73% [95% CI: 63%-82%] for those centres with universal screening vs. 10% [95% CI: 6%-15%] for those with a selective screening approach; p < 0.001). CONCLUSION: Our study provides useful data for policy makers and epidemiologists in a non-endemic area without congenital Chagas screening programmes.

Coping Strategies Used by Health Care Workers in Ecuador During the COVID-19 Pandemic: Observational Study to Enhance Resilience and Develop Training Tools.

BACKGROUND: The COVID-19 pandemic has generated immense health care pressure, forcing critical decisions to be made in a socially alarmed environment. Adverse conditions have led to acute stress reactions, affective pathologies, and psychosomatic reactions among health personnel, which have been exacerbated by the successive waves of the pandemic. The recovery of the entire health system and its professionals has been hindered, making it essential to increase their resilience. OBJECTIVE: This study aimed to achieve 2 primary objectives. First, it sought to identify coping strategies, both individual and organizational, used by health care workers in Ecuador to navigate the acute stress during the early waves of the pandemic. Second, it aimed to develop training materials to enhance team leaders' capabilities in effectively managing high-stress situations. METHODS: The study used qualitative research techniques to collect information on institutional and personal coping strategies, as well as consensus-building techniques to develop a multimedia psychological tool that reinforces the resilience of professionals and teams in facing future crises. RESULTS: The findings from the actions taken by health care workers in Ecuador were categorized into 4 types of coping strategies based on Lazarus' theories on coping strategies. As a result of this study, a new audiovisual tool was created, comprising a series of podcasts, designed to disseminate these strategies globally within the Spanish-speaking world. The tool features testimonials from health care professionals in Ecuador, narrating their experiences under the pressures of providing care during the pandemic, with a particular emphasis on the coping strategies used. CONCLUSIONS: Ensuring the preparedness of health professionals for potential future outbreaks is imperative to maintain quality and patient safety. Interventions such as this one offer valuable insights and generate new tools for health professionals, serving as a case study approach to train leaders and improve the resilience capacity and skills of their teams.

Clinical leadership and coping strategies in times of COVID-19: observational study with health managers in Mendoza.

BACKGROUND: The outbreak of the COVID-19 pandemic required an immediate response to the healthcare challenges it posed. This study was conducted to identify actions that helped healthcare professionals to overcome the initial impact in Mendoza (Argentina). METHODS: A cross-sectional study was carried out in a non-random sample of managers and staff of the public health system of Mendoza (Argentina) (n = 134). An ad-hoc and voluntary survey was carried out with 5 multi-response questions that combined questions referring to the management of the pandemic at the organizational level with others referring to coping at the individual level. The survey questions were formulated based on the results of six focus groups that were conducted previously. Descriptive frequency analysis was performed. RESULTS: 60 people agreed to participate and 45 answered the full questionnaire. At both the organizational and individual level, there was consensus with at least 50% of votes. The most outstanding at the organizational level was "Prioritize the need according to risk" and at the individual level it was "Support from family or friends", being also the most voted option in the whole questionnaire. CONCLUSIONS: The responses that emerged for coping with COVID-19 must be seen as an opportunity to identify strategies that could be effective in addressing future crisis situations that jeopardize the system's response capacity. Moreover, it is essential to retain both changes at the organizational level (e.g., new protocols, multidisciplinary work, shift restructuring, etc.) and coping strategies at the individual level (e.g., social support, leisure activities, etc.) that have proven positive outcomes.

Patient safety topics, especially the second victim phenomenon, are neglected in undergraduate medical and nursing curricula in Europe: an online observational study.

This study aims to assess the inclusion of second victims and other patient safety issues in the curricula of undergraduate medical and nursing degrees in the countries participating in the European Researchers' Network Working on Second Victims (The ERSNT Consortium, COST Action 19,113). A review of medical and nursing school curricula in 206 universities was carried out, using their websites to search for subjects addressing "patient safety", "quality of care", "risk management", "safe practices", "interprofessional communication", "adverse events", and "second victims". There was substantial variability in the extent of training for patient safety. Forty-four out of 88 nursing schools and 74 of 118 medical schools did not include any of the patient safety topics studied. The most frequent in both nursing and medicine was "interprofessional communication", followed by "quality of care" and basic aspects on "patient safety". The second victim phenomenon was present in only one curriculum of the total sample. Our study showed that patient safety, especially the second victim phenomenon, is still neglected in medical and nursing curricula in European universities, although positive initiatives were also found. Given the frequency with which adverse events occur in health centres and the need to prepare students to deal with them adequately, additional efforts are needed to introduce patient safety elements into medical and nursing education.

The impact of emotional support on healthcare workers and students coping with COVID-19, and other SARS-CoV pandemics - a mixed-methods systematic review.

BACKGROUND: Pandemics such as COVID-19 pose threats to the physical safety of healthcare workers and students. They can have traumatic experiences affecting their personal and professional life. Increasing rates of burnout, substance abuse, depression, and suicide among healthcare workers have already been identified, thus making mental health and psychological wellbeing of the healthcare workers a major issue. The aim of this systematic review is to synthesize the characteristics of emotional support programs and interventions targeted to healthcare workers and students since the onset of COVID-19 and other SARS-CoV pandemics and to describe the effectiveness and experiences of these programs. METHOD: This was a mixed method systematic review. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed, and the review was registered on PROSPERO [CRD42021262837]. Searches were conducted using Medline, CINAHL, PsycINFO, Cochrane Library, and Scopus databases. The COVIDENCE systematic review management system was used for data selection and extraction by two independent reviewers. The JBI (Joanna Briggs Institute) critical appraisal tools were used to assess the quality of selected studies by two additional reviewers. Finally, data extraction and narrative analysis were conducted. RESULTS: The search retrieved 3161 results including 1061 duplicates. After screening, a total of 19 articles were included in this review. Participants in studies were nurses, physicians, other hospital staff, and undergraduate medical students mostly working on the front-line with COVID-19 patients. Publications included RCTs (n = 4), quasi-experimental studies (n = 2), cross-sectional studies (n = 6), qualitative interview studies (n = 3), and systematic reviews (n = 4). Most (63.4%) of the interventions used online or digital solutions. Interventions mostly showed good effectiveness (support-seeking, positive emotions, reduction of distress symptoms etc.) and acceptance and were experienced as helpful, but there were some conflicting results. CONCLUSION: Healthcare organizations have developed support strategies focusing on providing emotional support for these healthcare workers and students, but it is difficult to conclude whether one program offers distinct benefit compared to the others. More research is needed to evaluate the comparative effectiveness of emotional support interventions for health workers.

Perceptions and attitudes of pediatricians and families with regard to pediatric medication errors at home.

PURPOSE: This study aimed to identify the perceptions and attitudes of pediatricians and parents/caregivers regarding medication errors at home, and to compare the findings from the two populations. METHODS: This was a cross-sectional survey study. We designed a survey for working pediatricians and another one for parents or caregivers of children aged 14 years and younger. The survey's questions were designed to assess provider and parental opinions about the difficulty faced by parents providing medical treatment, specific questions on medication errors, and on a possible intervention program aimed at preventing pediatric medication errors. Pediatrician and parent responses to matching questions in both surveys were compared. RESULTS: The surveys were administered in Spain from 2019 to 2021. In total, 182 pediatricians and 194 families took part. Most pediatricians (62.6%) and families (79.3%) considered that managing medical treatment was not among the main difficulties faced by parents in caring for their children. While 79.1% of pediatricians thought that parents consulted the internet to resolve doubts regarding the health of their children, most families (81.1%) said they consulted healthcare professionals. Lack of knowledge among parents and caregivers was one of the causes of medication errors most frequently mentioned by both pediatricians and parents. Most pediatricians (95.1%) said they would recommend a program designed to prevent errors at home. CONCLUSIONS: Pediatricians and families think that medical treatment is not among the main difficulties faced by parents in caring for their children. Most pediatricians said they would recommend a medication error reporting and learning system designed for families of their patients to prevent medication errors that might occur in the home environment.

Epidemiological study on gender bias and low-value practices in primary care: a study protocol.

INTRODUCTION: Evidence shows that gender has a substantial impact on health behaviours, access to and use of health systems and health system responses. This study aims to assess gender bias in patients subjected to low-value practices in the primary care setting and to develop recommendations for reducing adverse events that women experience for this reason. METHODS AND ANALYSIS: A Delphi study will be performed to reach a consensus on the 'Do Not Do' recommendations with a possible gender bias. A retrospective cohort study in a random selection of medical records will then be carried out to identify the frequency of adverse events that occur when the selected 'Do Not Do' recommendations are ignored. Qualitative research techniques (consensus conference and nominal group) will be carried out to develop recommendations to address any gender bias detected, considering barriers and facilitators in clinical practice. ETHICS AND DISSEMINATION: The study was approved by the ethics committee of San Juan de Alicante Hospital (San Juan de Alicante, Spain) Reference N. 21/061. We will disseminate the research findings via peer-reviewed articles, presentations at national and international scientific forums and webinars. TRIAL REGISTRATION NUMBER: The study was registered at ClinicalTrials.gov (NCT05233852) on 10 February 2022.

Comprehensive and heart-cutting multidimensional liquid chromatography-mass spectrometry and its applications in food analysis.

In food analysis, conventional one-dimensional liquid chromatography methods sometimes lack sufficient separation power due to the complexity and heterogeneity of the analysed matrices. Therefore, the use of two-dimensional liquid chromatography (2D-LC) turns out to be a powerful tool to consider, especially when coupled to mass spectrometry (MS). This review presents the most remarkable 2D-LC-MS food applications reported in the last 10 years, including a critical discussion of the multiple approaches, modulation strategies as well as the importance of the optimisation of the different analytical aspects that will condition the 2D-LC-MS performance. The presence of contaminants in food (food safety), the food quality and authenticity or the relationship between the beneficial effects of food and human health are some of the fields in which most of the 2D-LC-MS applications are mainly focused. Both heart-cutting and comprehensive applications are described and discussed in this review, highlighting the potential of 2D-LC-MS for the analysis of such complex samples.

Gastrointestinal symptoms and complications in patients hospitalized due to COVID-19, an international multicentre prospective cohort study (TIVURON project).

BACKGROUND: Retrospective studies suggest that coronavirus disease (COVID-19) commonly involves gastrointestinal (GI) symptoms and complications. Our aim was to prospectively evaluate GI manifestations in patients hospitalized for COVID-19. METHODS: This international multicentre prospective cohort study recruited COVID-19 patients hospitalized at 31 centres in Spain, Mexico, Chile, and Poland, between May and September 2020. Patients were followed-up until 15 days post-discharge and completed comprehensive questionnaires assessing GI symptoms and complications. A descriptive analysis as well as a bivariate and multivariate analysis were performer using binary logistic regression. p<0.05 was considered significant. RESULTS: Eight hundred twenty-nine patients were enrolled; 129 (15.6%) had severe COVID-19, 113 (13.7%) required ICU admission, and 43 (5.2%) died. Upon admission, the most prevalent GI symptoms were anorexia (n=413; 49.8%), diarrhoea (n=327; 39.4%), nausea/vomiting (n=227; 27.4%), and abdominal pain (n=172; 20.7%), which were mild/moderate throughout the disease and resolved during follow-up. One-third of patients exhibited liver injury. Non-severe COVID-19 was associated with ≥2 GI symptoms upon admission (OR 0.679; 95% CI 0.464-0.995; p=0.046) or diarrhoea during hospitalization (OR 0.531; 95% CI 0.328-0.860; p=0.009). Multivariate analysis revealed that worse hospital outcomes were not independently associated with liver injury or GI symptoms. CONCLUSION: GI symptoms were more common than previously documented, and were mild, rapidly resolved, and not independently associated with COVID-19 severity. Liver injury was a frequent complication in hospitalized patients not independently associated with COVID-19 severity.
