Abstract
A novel coronavirus discovered in late 2019 (COVID-19) quickly spread into a global epidemic and, thankfully, was brought under control by 2022. Because of the virus's unknown mutations and the vaccine's waning potency, forecasting is still essential for resurgence prevention and medical resource management. Computational efficiency and long-term accuracy are two bottlenecks for national-level forecasting. This study develops a novel multivariate time series forecasting model, the densely connected highly flexible dendritic neuron model (DFDNM) to predict daily and weekly positive COVID-19 cases. DFDNM's high flexibility mechanism improves its capacity to deal with nonlinear challenges. The dense introduction of shortcut connections alleviates the vanishing and exploding gradient problems, encourages feature reuse, and improves feature extraction. To deal with the rapidly growing parameters, an improved variation of the adaptive moment estimation (AdamW) algorithm is employed as the learning algorithm for the DFDNM because of its strong optimization ability. The experimental results and statistical analysis conducted across three Japanese prefectures confirm the efficacy and feasibility of the DFDNM while outperforming various state-of-the-art machine learning models. To the best of our knowledge, the proposed DFDNM is the first to restructure the dendritic neuron model's neural architecture, demonstrating promising use in multivariate time series prediction. Because of its optimal performance, the DFDNM may serve as an important reference for national and regional government decision-makers aiming to optimize pandemic prevention and medical resource management. We also verify that DFDMN is efficiently applicable not only to COVID-19 transmission prediction, but also to more general multivariate prediction tasks. It leads us to believe that it might be applied as a promising prediction model in other fields.

Abstract
This work reports the virucidal properties of nonwoven fibers developed via electrospinning with polycaprolactone (PCL) and chitosan quaternized with phosphonium salt (NPCS), emphasizing the influence of NPCS concentration on the structure of fibers and their performance against the MHV-3 coronavirus. The addition of NPCS enhances solutions conductivity and viscosity, leading to fibers containing a finer porous structure with a more hydrophilic and smoother surface, thereby making them a potent barrier against respiratory particles, which is a key factor for protective face masks. In terms of degradation, NPCS paced-up the process, suggesting potential environmental benefits. PCL/NPCS (90/10) fibers exhibit a 99 % coronavirus inhibition within a five-minute exposure without cellular toxicity, while also meeting breathability standards for medical masks. These findings suggest the use of NPCS as a promising strategy to design materials with remarkable virucidal performance and physical characteristics that reinforce their use in the field of biomaterials engineering.

Abstract
INTRODUCTION AND AIM SARS-CoV-2 emerged in 2019 and had a huge impact on the world. The area of endoscopy suffered great changes, causing a reduction in the number of procedures and its indications. The aim of our study was to compare the quantity, indication, and type of procedures in 2019 with those in 2020. METHOD A retrospective, observational, analytic, and cross-sectional study was conducted, obtaining information from the endoscopy registry. The STROBE checklist was employed. STATISTICAL ANALYSIS The quantitative variables were analyzed with descriptive statistics (measures of central tendency and dispersion) and the categorical variables with frequencies and percentages. The quantitative variables were compared, using the Student's t test/Mann-Whitney U test, and the categorical variables with contingency tables, using the Fisher's exact test. RESULTS In 2019, a total of 277 procedures were performed, compared with 139 in 2020. Mean patient age was 98.53 months (61.46 SD) in 2019 and 77.02 months (59.81 SD) in 2020; 352 diagnostic procedures and 136 therapeutic procedures were carried out in 2019, compared with 51 diagnostic procedures and 88 therapeutic procedures in 2020. The number of diagnostic and therapeutic procedures were inverted (72.1%-36.7% and 27.9%-63.3%, respectively) (p<0.0001). Esophageal varices, upper gastrointestinal bleeding (UGIB), and foreign body extraction were the indications, in order of predominance in 2019, compared with foreign body extraction (p<0.05), UGIB, and esophageal varices in 2020. There were no differences regarding colonoscopy. CONCLUSION There was a clear difference in indication and type of procedure, with an increase in foreign body extraction in preschoolers.

Abstract
Introduction Gastrointestinal bleeding in COVID-19-infection poses unique challenges to patients owing to the high risk of concomitant respiratory failure. However, endoscopic care providers are prone to transmission. This study aimed to understand the risk and management outcomes of gastrointestinal bleeding in COVID-19-infected patients. Methods Data were abstracted from electronic patient medical records, using ICD 10 codes, and demographic and clinical data were collected, for COVID-19-infected patients who developed gastrointestinal (GI) bleeding. Complications related to COVID-19 infection and management outcomes of GI bleeding were studied. Statistically, descriptive analysis was used because of the small sample size. Results Eighteen COVID-19-infected patients developed episodes of GI bleeding, yielding a prevalence of 0.45%. Their mean age was 74.8 years, 55.5% were female, and 66.6% of patients (n=12) had upper GI bleeding symptoms, predominantly melena (55.5%), followed by coffee ground nasogastric aspirates (n=2). Only two patients (11.11%) had episodes of lower GI bleeding, and the remaining four patients (22.2%) had recurrent acute anemia requiring blood transfusion. The Glasgow-Blatchford score (GBS) at presentation ranged between 6 to 16 (mean 8.8) and seven patients (38.8%) underwent endoscopic evaluation for GI bleeding. The predominant comorbid conditions included hypertension (22.2%), diabetes mellitus (27.7%), chronic kidney disease (50%), ischemic heart disease (33%), atrial fibrillation (11.1%), and peripheral vascular disease (11.1%). The median hospitalization was 24.6 days (range: 3-54 days). The 30-day mortality rate in our cohort was 22.2%, (4/18) mainly noted in older patients aged> 60 years with comorbid conditions and severe COVID-19 infection. Conclusion The prevalence of GI bleeding observed in our cohort was approximately 0.45%, significantly lower than the global prevalence observed, majority (66%) had upper GI bleeding. The exact reasons for the observed low prevalence of GI bleeding cannot be explained and will be the subject of future research.

Abstract
INTRODUCTION The coronavirus disease 19 (COVID-19) pandemic disrupted endoscopy practices, creating unprecedented decreases in cancer screening and surveillance services. We aimed to assess the impact of the pandemic on the proportion of patients diagnosed with Barrett's esophagus (BE) and BE-related dysplasia and adherence to established quality indicators. METHODS Data from all esophagogastroduodenoscopies in the GI Quality Improvement Consortium, a national repository of matched endoscopy and pathology data, were analyzed from January 2018 to December 2022. Four cohorts were created based on procedure date and COVID-19 data: pre-pandemic (January 2018 to February 2020), pandemic-phase I (March 2020 to July 2020), pandemic-phase II (August 2020 to May 2021), and pandemic-phase III (June 2021 to December 2022). Observed and expected number of BE and BE-related dysplasia cases per month and adherence to the Seattle biopsy protocol and recommended surveillance intervals for nondysplastic BE (NDBE) were evaluated. RESULTS Among 2,446,857 esophagogastroduodenoscopies performed during the study period, 104,124 (4.3%) had pathology-confirmed BE. The histologic distribution was 87.4% NDBE, 1.8% low-grade dysplasia, 2.4% indefinite for dysplasia, and 1.4% high-grade dysplasia. The number of monthly BE (-47.9% pandemic-phase I, -21.5% pandemic-phase II, and -19.0% pandemic-phase III) and BE-related dysplasia (high-grade dysplasia: 41.2%, -27.7%, and -19.0%; low-grade dysplasia: 49.1%, -35.3%, and -26.5%; any dysplasia: 46.7%, -32.3%, and -27.9%) diagnoses were significantly reduced during the pandemic phases compared with pre-pandemic data. Adherence rates to the Seattle protocol and recommended surveillance intervals for NDBE did not decline during the pandemic. DISCUSSION There was a significant decline in the number of BE and BE-related dysplasia diagnoses during the COVID-19 pandemic, with an approximately 50% reduction in the number of cases of dysplasia diagnosed in the early pandemic. The absence of a compensatory increase in diagnoses in the pandemic-phase II and III periods may result in deleterious downstream effects on esophageal adenocarcinoma morbidity and mortality.

Abstract
Background/Aims Non-time-sensitive gastrointestinal endoscopy was deferred because of the risk of exposure to coronavirus disease 2019 (COVID-19), but no population-based studies have quantified the adverse impact on gastrointestinal procedures. This study examined the impact of the COVID-19 pandemic on the performance of esophagogastroduodenoscopy (EGD), colonoscopy, ERCP, and abdominal ultrasonography (US) in South Korea. Methods This nationwide, population-based study compared the claim data of EGD, colonoscopy, ERCP, and abdominal US in 2020 and 2021 (COVID-19 era) with those in 2019 (before the COVID-19 era). Results During the first year (2020) of the COVID-19 pandemic, the annual claim data of EGD and colonoscopy were reduced by 6.3% and 6.9%, respectively, but those of ERCP and abdominal US were increased by 1.0% and 2.9%, compared to those in 2019. During the first surge (March and April 2020) of COVID-19, the monthly claim data of EGD, colonoscopy, ERCP, and abdominal US were reduced by 28.8%, 43.8%, 5.1%, and 21.6%, respectively, in March 2020, and also reduced by 17.2%, 32.8%, 4.4%, and 9.5%, respectively, in April 2020, compared to those in March and April 2019. During March and April 2020, the monthly claims of ERCP, compared with those in 2019, declined less significantly than those of EGD and colonoscopy (both p<0.001). Conclusions The claims of EGD and colonoscopy were reduced more significantly than those of ERCP and abdominal US during the COVID-19 pandemic because ERCPs are time-sensitive procedures and abdominal USs are non-aerosolized procedures.

Abstract
Introduction The COVID-19 pandemic drastically changed the daily routine of all healthcare systems worldwide, and endoscopy units were no exception. Endoscopic exams were considered to have a high risk of transmission, and therefore, the safety of endoscopy units and the consequent need for pre-endoscopy SARS-CoV-2 screening were questioned early on. The aim of our study was to assess the safety of endoscopy units during the COVID-19 pandemic, as well as the effectiveness/necessity for SARS-CoV-2 screening prior to endoscopies. Material and Methods This is a retrospective and single-center study carried out in a Portuguese tertiary hospital. All patients who underwent endoscopic procedures between September 1, 2020 and February 28, 2021 were included. The pre-endoscopy screening consisted of a specific questionnaire or a RT-PCR test for SARS-CoV-2 (nasal and oropharyngeal swab). Data were obtained through patient's clinical records and the Trace COVID platform. Results A total of 2,166 patients were included. Patients had a mean age of 61.8 years and were predominantly male (56.2%, n = 1,218). Eighty-one (3.7%) patients had previous SARS-CoV-2 infection, with a median difference of 74 days (IQ 40.5:160.5) between infection and endoscopy. Most patients (70.2%, n = 1,521) underwent PCR screening for SARS-CoV-2 up to 72 h before the procedure, with the remaining patients (29.8%, n = 645) answering a questionnaire of symptoms and risk contacts up to 3 days before endoscopy. Of the patients who underwent RT-PCR screening for SARS-CoV-2, 21 (1.4%) tested positive, and all were asymptomatic at the time of the screening. The evaluation for SARS-CoV-2 infection up to 14 days after the endoscopic exams identified 9 positive patients (0.42%) for SARS-CoV-2. The median difference in days between endoscopy and the diagnosis of infection was 10 days. Discussion/Conclusion Pre-endoscopy screening with RT-PCR test for SARS-CoV-2 identified a very small number of patients with COVID-19 infection as well as patients with COVID-19 infection in the following 14 days. Therefore, the risk of infection in endoscopy units is negligible if screening of symptoms and risk contacts is applied and individual protective equipment is used.

Abstract
Background Postponing elective surgeries during the COVID-19 pandemic has also affected the approach to both malignant and benign breast diseases. This paper aims to share how the COVID-19 pandemic affects our approach to breast cancer, benign breast cases, and the procedures' results. Methodology A cross-sectional study was conducted in a tertiary-level public hospital in Istanbul, Turkey. We retrospectively analyzed our treatment options for patients diagnosed with breast cancer and benign breast disease in the general surgery clinic of a tertiary hospital that declared a pandemic status between March 11, 2020, and June 1, 2020. Results The number of patients who visited the breast outpatient clinic and received a diagnosis of breast cancer was 23. Among the benign diseases, no intervention was made except for abscess (eight patients, 40%) and mastitis (12 patients, 60%). Conclusions Patients with acute abscesses and mastitis were treated for both diagnostic and therapeutic purposes. Chemotherapy and hormone therapy were chosen for those diagnosed with cancer. Priority was given to oncology protocols rather than surgical approaches during the pandemic. We think that different approaches will be defined as the pandemic continues.

Abstract
Since its emergence in early 2020, the SARS-CoV-2 infection has had a significant impact on the entire eye care system. Ophthalmologists have been categorized as a high-risk group for contracting the virus due to the belief that the eye may be a site of inoculation and transmission of the SARS-CoV-2 infection. As a result, clinical ophthalmologists, optometrists, and eyecare professionals have had to familiarize themselves with the ocular manifestations of COVID-19, as well as its treatments and vaccines. The implementation of measures to prevent the transmission of the virus, such as restrictions, lockdowns, telemedicine, and artificial intelligence (AI), have led to substantial and potentially irreversible changes in routine clinical practice, education, and research. This has resulted in the emergence of a new mode of managing patients in a routine clinical setting. This brief review aims to provide an overview of various aspects of COVID-19 in ophthalmology, including the ocular manifestations related to the disease, the modes of transmission of SARS-CoV-2 infection, precautions taken in ophthalmic practice to prevent the spread of the virus, drugs, and vaccines used in the treatment of COVID-19, the impact of the pandemic on patients, clinicians, and the eye care system as a whole, and the future of ophthalmology conditioned by this global pandemic experience.

Abstract
Despite the worldwide vaccination effort against COVID-19, the demand for biocidal materials has increased. One promising solution is the chemical modification of polysaccharides, such as chitosan, which can provide antiviral activity through the insertion of cationic terminals. In this study, chitosan was modified with (4-carboxybutyl) triphenylphosphonium bromide to create N-phosphonium chitosan (NPCS), a quaternized derivative. The resulting NPCS samples with three degrees of substitution (15.6 %, 19.8 % and 24.2 %) were characterized and found to have improved solubility in water and alkaline solutions but reduced thermal stability. The particles zeta potential exhibits positive charges and is directly correlated with the degree of substitution of the derivative. In virucidal assays, all NPCS samples were able to inhibit 99.999 % of the MHV-3 coronavirus within 5 min at low concentrations of 0.1 mg/mL, while maintaining low cytotoxicity to L929 cells. In addition to its potential application against current coronavirus strains, NPCS could also be valuable in combating future pandemics caused by other viral pathogens. The antiviral properties of NPCS make it a promising material for use in coating surface and personal protective equipment to limit the spread of disease-causing viruses.

Abstract
BACKGROUND Healthcare workers (HCWs) are at a high risk of SARS-CoV-2 infection due to exposure to potentially infectious material, especially during aerosol-generating procedures (AGP). We aimed to investigate risk factors for SARS-CoV-2 infection among HCWs in medical disciplines with AGP. METHODS A nationwide questionnaire-based study in private practices and hospital settings was conducted between 12/16/2020 and 01/24/2021. Data on SARS-CoV-2 infections among HCWs and potential risk factors of infection were investigated. RESULTS 2070 healthcare facilities with 25113 employees were included in the study. The overall infection rate among HCWs was 4.7%. Multivariate analysis showed that regions with higher incidence rates had a significantly increased risk of infection. Furthermore, hospital setting and HCWs in gastrointestinal endoscopy (GIE) had more than double the risk of infection (OR 2.63; 95% CI 2.50-2.82, p<0.01 and OR 2.35; 95% CI 2.25-2.50, p<0.01). For medical facilities who treated confirmed SARS-CoV-2 cases, there was a tendency towards higher risk of infection (OR 1.39; 95% CI 1.11-1.63, p=0.068). CONCLUSION Both factors within and outside medical facilities appear to be associated with an increased risk of infection among HCWs. Therefore, GIE and healthcare delivery setting were related to increased infection rates. Regions with higher SARS-CoV-2 incidence rates were also significantly associated with increased risk of infection.

THE IMPACT OF THE COVID-19 PANDEMIC ON ENDOSCOPIC ULTRASOUND PROCEDURES IN A HIGH-VOLUME ENDOSCOPY UNIT IN BRAZIL. ARQUIVOS DE GASTROENTEROLOGIA 2023; 60:364-372. [PMID: 37792767 DOI: 10.1590/s0004-2803.230302023-75] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/19/2023] [Accepted: 07/27/2023] [Indexed: 10/06/2023]
Abstract
•In pancreatic neoplasms the EUS plays a key role in the management. •During the pandemic period, lockdown measures prevented patients with comorbidities from performing EUS. •The D-EUS decreased during COVID-19, while I-EUS increased and EUS-TA was the most commonly I-EUS procedure performed, with no increase in adverse events. •Despite the moderate impact of the pandemic period in endoscopic services around the world, EUS-TA of solid and cystic tumors of the pancreas was the main indication. Background - Reports of the impact of the 2020 COVID-19 pandemic period/2020 on endoscopic ultrasound (EUS) are scarce. Objective - We analyzed the impact of the pandemic period/2020 on the demographics, indications, and number of diagnostic EUS (D-EUS) and interventional EUS (I-EUS) procedures performed in a high-volume endoscopy unit compared with the previous non-pandemic period/2019. Methods - We retrospectively reviewed the medical records of all patients undergoing D-EUS or I-EUS from March 1, 2019, to February 29, 2020 (non-pandemic period/2019) and from March 1, 2020, to February 28, 2021 (pandemic period/2020). Data compared between the study periods included sex, age, comorbidities, EUS findings and diagnosis, need for interventional procedures during EUS, and adverse events (AEs). Results were significant at P<0.05. Results - EUS procedures decreased from 475 in the non-pandemic period/2019 to 289 in the pandemic period/2020, accounting for a 39% reduction. In non-pandemic period/2019, 388 (81.7%) D-EUS and 88 (18.5%) I-EUS were performed, against 206 (71.3%) D-EUS and 83 (28.7%) I-EUS in pandemic period/2020 (P=0.001). Only 5/289 (1.7%) patients had COVID-19. Fewer patients with comorbidities underwent EUS during pandemic period/2020 due to lockdown measures (P<0.001). D-EUS decreased, whereas I-EUS increased (P<0.001). EUS-guided tissue acquisition (EUS-TA) was the most common I-EUS, performed in 83/289 (28.7%) patients in pandemic period/2020, against 88/475 (18.5%) in non-pandemic period/2019 (P=0.001). AEs did not differ significantly between the study periods. Conclusion - Pandemic Period/2020 had a moderate impact on reducing EUS procedures due to the risks involved. Although I-EUS increased, EUS-related AEs did not. Solid and cystic pancreatic tumors remained a major indication for EUS-TA even during the pandemic period/2020.

Abstract
Background To contain the spread of infection and reduce the burden on healthcare infrastructure, many countries globally adopted a lockdown strategy during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. Hospitals were converted to dedicated coronavirus disease 2019 (COVID-19) centers, and non-COVID-19 patients were intervened on a triage basis. During this time, only emergency procedures were performed. The impact of this lockdown strategy during the first wave of the SARS-CoV-2 pandemic on various gastrointestinal endoscopy interventions remains unknown. Methodology In this retrospective, observational study conducted in the Department of Gastroenterology, Indira Gandhi Institute of Medical Sciences, Patna, Bihar from March 25 to September 30, 2020, data related to clinical profile, indication, and endoscopic interventions performed in reverse transcriptase-polymerase chain reaction (RT-PCR)-negative patients with the use of personal protective kits were analyzed and compared with the historical controls. Results A total of 2,282 patients were admitted and 422 endoscopic procedures were performed during the six-month study period with an intervention rate of 18.49%. The most common procedure was upper gastrointestinal endoscopy (228, 58.13%), followed by endoscopic retrograde cholangiopancreatography (ERCP) (88, 22.50%). Chronic liver disease (CLD) (144 patients) followed by malignancy (111 patients) were the most common diagnosis. During the first phase of the lockdown (March to May), only 52 procedures were performed (52 vs. 506). None of the patients underwent endoscopic ultrasound. In 2019, 4,501 patients were admitted and 1,224 procedures were performed with an intervention rate of 27.19 (p < 0.0001). None of the staff of the Department of Gastroenterology developed symptomatic SARS-CoV-2 infection during this period. Conclusions There was a significant drop in endoscopic procedures during the lockdown and most of the esophagoduodenoscopy procedures were done for CLD and ERCP for biliary tract malignancy. Endoscopic procedures done on RT-PCR for COVID-19-negative patients were safe using personal protective kits.

Abstract
BACKGROUND Colorectal cancer (CRC) is a common neoplasm in Western countries. Prioritizing access to colonoscopy appears of critical relevance. Alarm features are considered to increase the likelihood of CRC. Our aim was to assess the diagnostic performance of alarm features for CRC diagnosis. METHODS We performed a systematic review and meta-analysis of studies reporting the diagnostic accuracy of alarm features (rectal bleeding, anemia, change in bowel habit, and weight loss) for CRC, published up to September 2021. Colonoscopy was required as the reference diagnostic test. Diagnostic accuracy measures were pooled by a bivariate mixed-effects regression model. The number needed to scope (NNS; i. e. the number of patients who need to undergo colonoscopy to diagnose one CRC) according to each alarm feature was calculated. RESULTS 31 studies with 45 100 patients (mean age 31-88 years; men 36 %-63 %) were included. The prevalence of CRC ranged from 0.2 % to 22 %. Sensitivity was suboptimal, ranging from 12.4 % for weight loss to 49 % for rectal bleeding, whereas specificity ranged from 69.8 % for rectal bleeding to 91.9 % for weight loss. Taken individually, rectal bleeding and anemia would be the only practical alarm features mandating colonoscopy (NNS 5.3 and 6.7, respectively). CONCLUSIONS When considered independently, alarm features have variable accuracy for CRC, given the high heterogeneity of study populations reflected by wide variability in CRC prevalence. Rectal bleeding and anemia are the most practical to select patients for colonoscopy. Integration of alarm features in a comprehensive evaluation of patients should be considered.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a novel coronavirus, causes coronavirus disease 2019 (COVID-19) which led to neurological damage and increased mortality worldwide in its second and third waves. It is associated with systemic inflammation, myocardial infarction, neurological illness including ischemic strokes (e.g., cardiac and cerebral ischemia), and even death through multi-organ failure. At the early stage, the virus infects the lung epithelial cells and is slowly transmitted to the other organs including the gastrointestinal tract, blood vessels, kidneys, heart, and brain. The neurological effect of the virus is mainly due to hypoxia-driven reactive oxygen species (ROS) and generated cytokine storm. Internalization of SARS-CoV-2 triggers ROS production and modulation of the immunological cascade which ultimately initiates the hypercoagulable state and vascular thrombosis. Suppression of immunological machinery and inhibition of ROS play an important role in neurological disturbances. So, COVID-19 associated damage to the central nervous system, patients need special care to prevent multi-organ failure at later stages of disease progression. Here in this review, we are selectively discussing these issues and possible antioxidant-based prevention therapies for COVID-19-associated neurological damage that leads to multi-organ failure.

Abstract
Background During the COVID-19 pandemic, many nonurgent oncologic services were postponed. The aim of the present study was to estimate the impact of the pandemic on visits and hospital admissions for cancer patients worldwide. Methods In our systematic review and meta-analysis, databases such as Pubmed, Proquest, and Scopus were searched comprehensively for articles published between January 1, 2020, and December 12, 2021. We included articles reporting data comparing the number of visits and hospital admissions for oncologic patients performed before and during the pandemic. Two pairs of independent reviewers extracted data from the selected studies. The weighted average of the percentage change was calculated and compared between pandemic and pre-pandemic periods. Stratified analysis was performed by geographic area, time interval, and study setting. Findings We found a mean relative change throughout January-October 2020 of -37.8% (95% CI -42.6; -32.9) and -26.3% (95% CI -31.4; -21.1) compared to pre-pandemic periods for oncologic visits and hospital admission, respectively. The temporal trend showed a U-shaped curve with nadir in April for cancer visits and in May 2020 for hospital admissions. All geographic areas showed a similar pattern and the same was observed when stratifying the studies as clinic-based and population-based. Interpretation Our results showed a decrease in the number of visits and hospital admission during the January-October 2020 period after the outbreak of the COVID-19 pandemic. The postponement or cancellation of these oncologic services may negatively affect the patient's outcome and the future burden of disease.

Abstract
PurposeDuring the coronavirus disease 2019 (COVID-19) pandemic, ubiquitous social media has become a primary channel for information dissemination, social interactions and recreational activities. However, it remains unclear how social media usage influences nonpharmaceutical preventive behavior of individuals in response to the pandemic. This paper aims to explore the impacts of social media on COVID-19 preventive behaviors based on the theoretical lens of empowerment.Design/methodology/approachIn this paper, survey data has been collected from 739 social media users in China to conduct structural equation modeling (SEM) analysis.FindingsThe results indicate that social media empowers individuals in terms of knowledge seeking, knowledge sharing, socializing and entertainment to promote preventive behaviors at the individual level by increasing each person's perception of collective efficacy and social cohesion. Meanwhile, social cohesion negatively impacts the relationship between collective efficacy and individual preventive behavior.Originality/valueThis study provides insights regarding the role of social media in crisis response and examines the role of collective beliefs in the influencing mechanism of social media. The results presented herein can be used to guide government agencies seeking to control the COVID-19 pandemic.

Abstract
Coronavirus (COVID-19) infection usually causes mild symptoms in children. However, serious complications may occur as a result of both acute infection or in association with the multisystem inflammatory syndrome (MIS-C). Dysphagia may develop as a sequela of COVID-19. We review the limited data on dysphagia associated with COVID-19 infection in children. Children can develop acute respiratory distress syndrome (ARDS) due to severe COVID-19 infection leading to endotracheal intubation and mechanical ventilation. These children can possibly develop post-intubation dysphagia. Screening for the presence of dysphagia, in an effort to minimize aspiration, in children with active COVID-19 infection must be done carefully to reduce the risk of transmission of the virus. Those children diagnosed with persistent dysphagia after COVID-19 infection has resolved will need further evaluation and management by pediatric subspecialists experienced in treating children with this condition. We recommend, this evaluation and treatment be done by a pediatric aerodigestive team.

Lockdown period during SARS COVID-19 endemic outbreak in Taiwan did not cause an increase of the complications nor mortality of patients received endoscopic retrograde cholangiopancreatography: A single-center retrospective study.

Abstract
BACKGROUND Coronavirus disease 2019, known as a widespread, aerosol spreading disease, has affected >549 000 000 people since 2019. During the lockdown period, dramatic reduction of elective endoscopic procedures, including endoscopic retrograde cholangiopancreatography, had been reported worldwide, leading to delayed diagnosis and treatment. Nevertheless, whether patients' hospital stays and complication rate of endoscopic retrograde cholangiopancreatography (ERCP) during the lockdown period were influenced by the pandemic still remains controversial. METHODS Patients who diagnosed with obstructive jaundice and acute cholangitis in the lockdown period, May 16 to July 26, 2021, were compared to the same prepandemic period in 2019. RESULTS A total of 204 patients in 2019 and 168 patients in 2021 were diagnosed with acute biliary cholangitis or obstructive jaundice, and 82 of the patients in 2019 and 77 patients in 2021 underwent ERCP ( p = 0.274). Patients whose quick Sequential Organ Failure Assessment (qSOFA) score was ≥ 2 occurred more during the lockdown period than during the normal period (24/77, 31.1% vs 12/82, 14.6%; p = 0.013). The initial laboratory data, including, total bilirubin (4.12 in 2021 vs 3.08 mg/dL in 2019; p = 0.014), gamma-glutamyl transferase (378 in 2021 vs 261 U/L in 2019; p = 0.009), and alkaline phosphatase (254 in 2021 vs 174 U/L in 2019; p = 0.002) were higher during the lockdown period compared to 2019. Hospital stay was statistically significant longer in the lockdown period (11 days [7.00-22.00] in 2021 vs 8 days in 2019 [6.00-12.00]; p value = 0.02). Multivariate analysis showed that qSOFA ≥ 2 (hazard ratio [HR] = 3.837, 95% confidence interval [CI] = 1.471-10.003; p = 0.006), and malignant etiology (HR = 2.932, 95% CI = 1.271-6.765; p = 0.012) were the statistically significant factors for a prolonged hospital stay, which was defined as hospital stay >21 days. ERCP-related complications and mortality rate were not statistically different between the two periods. CONCLUSION Patients from May 16 to July 26, 2021, the lockdown period, had longer hospital stays and higher biliary tract enzyme levels, which indicated more severe disease. Nevertheless, ERCP could be safely and successfully performed even during the medical level 3 alert lockdown period without causing an increase in procedure-related complications and mortality.

Abstract
With the development and generalization of endoscopic technology and screening, clinical application of magnetically controlled capsule gastroscopy (MCCG) has been increasing. In recent years, various types of MCCG are used globally. Therefore, establishing relevant guidelines on MCCG is of great significance. The current guidelines containing 23 statements were established based on clinical evidence and expert opinions, mainly focus on aspects including definition and diagnostic accuracy, application population, technical optimization, inspection process, and quality control of MCCG. The level of evidence and strength of recommendations were evaluated. The guidelines are expected to guide the standardized application and scientific innovation of MCCG for the reference of clinicians.

Abstract
BACKGROUND The rapid spread of coronavirus disease 2019 (COVID-19) has attracted worldwide attention. There were also reported gastrointestinal symptoms in patients with COVID-19. This work aims to analyze the global research trends in COVID-19 and digestive disease. METHODS The related papers on COVID-19 and digestive disease were identified with Pubmed and web of science core collection on September 3, 2021. Bibliometric visualization was conducted through VOSviewer and CiteSpace. RESULTS The analytic research was based on original articles and reviews. There were 997 articles found, with citations ranging from 0 to 878. These articles were distributed among 86 countries and 355 journals. The USA mainly contributed (288 articles), where 3 of the top 10 institutions were located. Followed by China (215 articles) and Italy (160 articles). The highest level of scientific collaboration has been formed between the USA to China. The World Journal of Gastroenterology (39 papers) published the most significant number of articles. Concerning the research topic, the colon/small bowel had the largest number of articles, followed by the liver and pancreaticobiliary. "Liver injury," "inflammatory bowel disease," "management," and "endoscopy" were the hotspot keywords. The largest cluster of liver transplantation had offered hints regarding research frontiers. CONCLUSION The analytic results showed that the liver, especially liver transplantation, and inflammatory bowel disease were the 2 most influential research topics in COVID-19 and digestive disease.

Abstract
The COVID-19 pandemic is ongoing and places a substantial burden on healthcare systems worldwide. As we further shed light on different disease characteristics, we identify more and more groups of people at higher risk of poor COVID-19 outcomes. Metabolic-associated fatty liver disease (MAFLD) (previously non-alcoholic fatty liver disease or NAFLD) is a common metabolic disorder characterized by fat accumulation and liver fibrosis. Given its close correlation with metabolic syndrome, an established risk factor for severe COVID-19, it is necessary to investigate its interplay with the novel coronavirus. In this study, we review the available data on COVID-19 prognosis, treatment and prevention options in patients with MAFLD, and the effect that the disease and the pandemic have on MAFLD care. Furthermore, we point out the gaps in the current literature to accentuate the work that needs to be done to improve MAFLD care during the pandemic and beyond.

Abstract
BACKGROUND This study aims to examine the clinical characteristics and prognosis of patients with chest trauma who were infected with COVID-19 and underwent emergency surgery. OBJECTIVE In light of the COVID-19 pandemic, this research investigates the impact of COVID-19 on patients with chest trauma who underwent emergency surgery. METHODS This retrospective cohort study was conducted on 56 patients with chest trauma in two groups with COVID-19, and no covid who underwent surgery in Shahid Madani Hospital. RESULTS Among the trauma patients, 21 were infected with COVID-19, and 35 were not. The predominant causes of trauma were car and motorcycle accidents. Among COVID-19 patients, 3.3% exhibited symptoms of fever, chills, cough, shortness of breath, and gastrointestinal symptoms, while 5.9% had severe lung involvement confirmed by CT scan. Following surgery, 1.57% (12 individuals) of COVID-19 patients were transferred to the ICU, with an average hospitalization duration of 1.11 days. In contrast, the average hospitalization duration for non-COVID-19 chest trauma patients was 1.9 days (p =0.015). CONCLUSION Patients with chest trauma who underwent surgery and were infected with COVID-19 demonstrated significant differences in average length of stay, ICU admissions, and pneumonia incidence. However, there was no significant distinction in the mortality rate between the two groups.

Abstract
January 2020 marked the very early period of SARS-CoV-2's arrival in Japan. At the time, we immediately and strictly adopted the use of enhanced PPE, including a N95, gown, gloves, eye protection, and an apron, during every endoscopic procedure for every patient, with or without COVID-19. One reason why we use enhanced PPE for every patient is because all endoscopic procedures should be considered aerosol-generating procedures, and another reason is that asymptomatic patients with COVID-19 cannot be identified during a pandemic. The volume of endoscopic screening/surveillance endoscopies decreased markedly, but therapeutic endoscopies did not decrease. In contrast, urgent endoscopic hemostasis has increased more than ever. The most common reason for the increase might be that the lack of protective equipment and the need for medical staff to deal with an unknown virus, creating a pandemic panic in emergency medicine.

Abstract
BACKGROUND There are difficulties in diagnosing nosocomial transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in hospital settings. Furthermore, mortality of cases of nosocomial infection (NI) with SARS-CoV-2 is higher than that of the general infected population. In the early stage of the pandemic in Taiwan, as patients were not tested for SARS-CoV-2 at admission, NIs often go undetected. Strictly applying the systematic polymerase chain reaction (PCR) screening, as a standard infection control measure was subsequently implemented to reduce NI incidence. However, evidence on risk factors for SARS-CoV-2 NIs among healthcare workers (HCWs) and caregivers is limited. AIM To assess NI incidence of SARS-CoV-2 among hospital staff, hospitalized patients, and caregivers, and the transmission routes of clusters of infection. METHODS This descriptive retrospective analysis at our hospital from May 15 to August 15, 2021 included data on 132 SARS-CoV-2 NIs cases among hospital staff, inpatients, and caregivers who previously tested negative but subsequently identified with a positive SARS-CoV-2 reverse transcriptase-PCR (RT-PCR) test results, or a hospital staff who tested positive following routine SARS-CoV-2 RT-PCR test. Chi-square tests were performed to compare the differences between hospital staff and private caregivers, and between clusters and sporadic infections. RESULTS Overall, 9149 patients and 2005 hospital staff members underwent routine SARS-CoV-2 RT-PCR testing, resulting in 12 confirmed cluster and 23 sporadic infections. Among the index cases of the clusters, three (25%) cases were among hospital staff and nine (75%) cases were among other contacts. Among sporadic infections, 21 (91%) cases were among hospital staff and two (9%) cases were among other contacts (P < 0.001). There was an average of 8.08 infections per cluster. The secondary cases of cluster infection were inpatients (45%), hospital staff (30%), and caregivers (25%). Private caregivers constituted 27% and 4% of the clusters and sporadic infections, respectively (P = 0.024); 92.3% of them were infected in the clusters. The mortality rate was 0.0%. CONCLUSION The incidence of SARS-CoV-2 infection was relatively high among private caregivers, indicating a need for infection control education in this group, such as social distancing, frequent hand-washing, and wearing PPE.

Abstract
Background The management of inflammatory bowel disease (IBD) requires frequent endoscopic assessment. It is unknown if measures put in place to reduce the spread of the virus SARS-CoV-2, including the delay of non-urgent patient assessments, resulted in deleterious outcomes for patients with IBD. Therefore, we aimed to determine if delays in endoscopy during the COVID-19 pandemic were associated with an increased risk of adverse IBD outcomes (emergency room, ER presentation, hospitalization, surgery, or escalation of drug therapy). Methods A retrospective cohort study was performed in patients with IBD scheduled for outpatient endoscopies between March and August 2019 and 2020 at two tertiary care centers affiliated with Western University, London, Canada. Data pertaining to endoscopy timing, IBD drug prescription, ER attendance, hospitalization, and surgery were collected. Results A total of 1160 endoscopies (2019, n = 718; 2020, n = 442) occurred during the study periods in 669 (2019) and 414 (2020) patients with IBD, respectively. More endoscopies were delayed in 2020 than 2019 (26.7% vs. 9.7%, respectively, P < 0.0001). Endoscopy delay was not associated with an increased risk of an adverse IBD outcome (OR = 1.23, 95%CI = 0.89-1.34, P = 0.20). Fewer adverse IBD outcomes were seen in the 2020 cohort who had endoscopy delays (n = 33/115, 28.7%) versus those without delay (n = 176/299, 58.9%, P < 0.0001). Conclusion More endoscopy delays occurred during the COVID-19 pandemic; however, delays in general were not associated with adverse IBD outcomes, and in particular, endoscopy delays during the COVID-19 pandemic were associated with fewer deleterious IBD outcomes, suggesting that patients with IBD in need of urgent endoscopy were appropriately identified.

Abstract
Coronavirus refers to a group of widespread viruses. The name refers to the specific morphology of these viruses because their spikes look like a crown under an electron microscope. The outbreak of coronavirus disease 2019 (COVID-19) that has been reported in Wuhan, China, in December 2019, was proclaimed an international public health emergency (PHEIC) on 30 January 2020, and on 11 March 2020, it was declared as a pandemic (World Health Organization 2020). The official name of the virus was declared by the WHO as "COVID-19 virus", formerly known as "2019-nCoV", or "Wuhan Coronavirus". The International Committee on Virus Taxonomy's Coronavirus Research Group has identified that this virus is a form of coronavirus that caused a severe outbreak of acute respiratory syndrome in 2002-2003 (SARS). As a result, the latest severe acute respiratory syndrome has been classified as a corona virus 2 (SARS-CoV-2) pathogen by this committee. This disease spread quickly across the country and the world within the first 3 months of the outbreak and became a global pandemic. To stop COVID-19 from spreading, the governing agencies used various chemicals to disinfect different commercial spaces, streets and highways. However, people used it aggressively because of panic conditions, anxiety and unconsciousness, which can have a detrimental impact on human health and the environment. Our water bodies, soil and air have been polluted by disinfectants, forming secondary products that can be poisonous and mutagenic. In the prevention and spread of COVID-19, disinfection is crucial, but disinfection should be carried out with sufficient precautions to minimize exposure to harmful by-products. In addition, to prevent inhalation, adequate personal protective equipment should be worn and chemical usage, concentrations, ventilation in the room and application techniques should be carefully considered. In the USA, 60% of respondents said they cleaned or disinfected their homes more often than they had in the previous months. In addition to the robust use of disinfection approaches to combat COVID-19, we will explore safe preventative solutions here.

Abstract
BACKGROUND Portal hypertension is considered as a major complication of liver cirrhosis. Endoscopy plays a main role in managing of gastrointestinal complications of portal hypertension. Endoscopists are at increased risk for COVID-19 infection because upper gastrointestinal (GI) endoscopy is a high-risk aerosol-generating procedure and may be a potential route for COVID-19. OBJECTIVES To compare the outcome between cirrhotic patients who underwent classic regular endoscopic variceal ligation after primary bleeding episode every 2-4 weeks, and those presented during the era of COVID-19 and their follow-up were postponed 2 months later. METHODS This retrospective study included cross-matched 238 cirrhotic patients with portal hypertension presented with upper GI bleeding, 112 cirrhotic patients presented during the era of COVID19 (group A) underwent endoscopic variceal ligation, another session after 2 weeks and their subsequent follow-up was postponed 2 months later, and 126 cirrhotic patients as control (group B) underwent regular endoscopic variceal band ligation after primary bleeding episode every 2-4 weeks. RESULTS Eradication of varices was achieved in 32% of cases in group A, and 46% in group was not any statistically significant (p > 0.05); also, there was no any statistical significant difference between both groups regarding occurrence of rebleeding, post endoscopic symptoms, and mortality rate (p > 0.05). CONCLUSION Band ligation and injection of esophageal and gastric vary every 2 months were as effective and safe as doing it every 2 to 4 weeks after primary bleeding episode for further studies and validation.

Abstract
Abstract
Background
Gastrointestinal (GI) bleeding is one of the most impactful complications in patients hospitalized from COVID-19 infection. Limited study has focused on patients with upper GI bleeding (UGIB). This study aimed to identify the risk factors of patients who were hospitalized from COVID-19 infection and developed UGIB as well as the effectiveness of proton pump inhibitor (PPI) prophylaxis in those patients.
Methods
This study was comprised of two phases. The first phase was the retrospective enrollment of patients who were admitted due to COVID-19 infection and developed UGIB between April and August 2021 to evaluate the associated factors of active UGIB. The second phase was a retrospective analysis after PPI prophylaxis protocol from September – October 2021 to assess the benefit of PPI use in those patients.
Results
Of 6,373 patients hospitalized, 43 patients (0.7%) had evidence of UGIB. The majority were male 28 (65.1%) with a mean age of 69.1 ± 11.8 years. Twenty-four of 43 patients (55.8%) needed mechanical ventilation, 35 patients (81.4%) received systemic corticosteroids, and 10 patients (23.3%) were taking anticoagulants for venous thromboembolic prophylaxis. Seven of 43 patients (16%) had active UGIB. There was no significant difference in the number of patients taking antiplatelets, anticoagulants, or steroids and the severity of COVID-19 infection between the two groups. An emergency endoscopy or endoscopic hemostasis were performed in 6/7 (85.7%) patients. The multivariate logistic regression analysis revealed two significant factors associated with active UGIB including higher of Glasgow-Blatchford score (GBS) per point (OR = 7.89; 95%CI 1.03–72.87; p = 0.04) and an absence of PPI use (OR 4.29; 95%CI 1.04–19.51; p = 0.04). After prescribing PPI as a prophylaxis, there was a slightly lower incidence of UGIB (0.6% vs 0.7%) in addition to an absence of active UGIB (0% vs 16%).
Conclusion
Our study demonstrated that the absence of PPI and higher GBS were significant risk factors for active UGIB which required therapeutic endoscopy in patients with COVID-19 infection. We suggest that short-term PPI prophylaxis should be prescribed in those patients once they need hospitalization regardless of the severity of COVID-19 infection to minimize the severity of UGIB.

Abstract
The impact of the COVID-19 pandemic caused a decrease in healthcare services, the intervention of non-surgical procedures, and endoscopy. This study examined the volume of endoscopy at Dr. Cipto Mangukusumo Hospital, the highest referral hospital in Indonesia. A cross-sectional mixed method was used to assess the relationship between endoscopy volume, age, gender, number of COVID-19 cases, type of patient's case, the origin of treatment, and the kind of endoscopic procedure before and during the pandemic. The secondary data were collected through the hospital's Electronic Health Record (EHR) System and "Kawal COVID-19" Websites, while the primary data were collected through observation, document reviews, and in-depth online interviews with doctors at endoscopic units. This study period was divided into six intervals of three months, respectively, from January 2020 to September 2021, and 5030 endoscopic procedures were collected. The data were analyzed both quantitatively through the SPSS statistics and qualitatively. The quantitative data presented as descriptive and bivariate results in an Independent T-Test and a Chi-Square test. The results showed there was a significant difference (p = 0.004) in the volume of endoscopes before (the highest volume) and during the pandemic (the lowest volume during April-June 2020 period). The mean age of the patients was higher before the pandemic. There was a significant difference between patient admissions from outpatient and emergency procedures before and during the pandemic. There are changes in the flow of outpatient to do endoscopies which were different from the flow of emergency patients during the pandemic, which focused on the long waiting list for inward entry queues, the mandatory COVID-19 PCR swab, and the criteria of emergency cases for fast-track procedures, the reduced bed capacity, and the expired date of laboratory examinations. The decreased volume was also caused by the limitation of patient intervention by the doctors. However, the duration of the action procedure was accelerated without reducing its quality. Furthermore, there was a high wave of Delta Variant cases from May to July 2021. In addition, the factors of age, type of patient's case, origin, and treatment showed significant differences before and during the COVID-19 pandemic. Finally, changes in the flow of services also influenced various impacts on endoscopy and service costs. Therefore, further study is required to calculate the unit costs.

Abstract
The primary aim was to assess the role of mental and physical health of COVID-19 and its psychological impact in the general population of Pakistan during the first wave of COVID-19. It was hypothesized that there would be a significant predictive association among socio-demographic variables, psychological impact and mental health status resulting from COVID-19, and poor self-reported physical health would be significantly associated with adverse psychological impact and poor mental health status because of COVID-19. A cross-sectional survey research design was used in which 1,361 respondents were sampled online during lockdown imposed in the country. The Impact of Events Scale-Revised (IES-R) was used to assess the psychological impact of COVID-19, and the Depression Anxiety Stress Scales (DASS-21) was used to assess participants’ mental health status. 18% of the respondents reported moderate to severe event-specific distress, 22.6% reported moderate to severely extreme depression, 29% reported moderate to extreme anxiety, and 12.1% reported moderate to extreme stress. Female gender, having graduate-level education, currently studying, and self-reported physical symptoms (persistent fever, chills, headache, cough, breathing difficulty, dizziness, and sore throat) were significantly associated with higher levels of psychological impact exhibited through higher scores on the IES-R and poorer mental health status exhibited through higher scores on the DASS-21 (Depression, Anxiety, and Stress Subscales).

Abstract
Although the coronavirus disease 2019 (COVID-19) pandemic has reached all over the world population, it has demonstrated a heterogeneous impact on different populations. The most vulnerable communities which coexist daily with the social inequalities like low access to hygiene and personal protection products, crowded residences, and higher levels of chronic diseases have a higher risk of contact and the spread of infection, beyond unfavorable clinical outcomes. The elevation of the risk of infection exposure can be related to gender due to the presence of a larger contingent of women in essential services, as well as frontline and cleaning professionals who regardless of gender have the greatest exposure to the virus. Such exposures can contribute to the development of fear of contaminating themselves or their family members associated also with the work stress, both of which are related to the emergence of mental disturbances in these populations. Furthermore, conditions of unsanitary living and low socioeconomic status, populations at war, pre-existing social barriers, and ethnicity have contributed to more impact of the pandemic both in the exposure to the virus and access to health services, COVID-19 management, and management of other pathologies. At the same time, factors such as the closing of non-essential services, the loss of jobs, and the increase in household spending aggravated the social vulnerabilities and impacted the family economy. Lastly, the COVID-19 pandemic contributed still more to the impact on women's health since it propitiated a favorable environment for increasing domestic violence rates, through the segregation of women from social life, and increasing the time of the victims with their aggressors.

Abstract
Background and objectives Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is a complex treatment used in selected patients with peritoneal surface malignancies. HIPEC procedures are time and resource intensive. The primary aim of this analysis was to compare the experience of treating advanced abdominal tumors with CRS‐HIPEC before and during the coronavirus disease 2019 (COVID‐19) pandemic. Methods Patients included in this analysis received CRS‐HIPEC at a single center during either a prepandemic (March 18, 2019–March 17, 2020) or pandemic (March 18, 2020–February 5, 2021) interval. A retrospective chart review was performed. Results Our analysis included 67 patients: 30 (45%) treated prepandemic and 37 (55%) treated during the pandemic. Median age at the time of operation was 58 years (interquartile range: [49–65]); 53% of patients were women. Patients treated during the pandemic presented with higher peritoneal cancer index (PCI) scores with 32% (n = 12) having a PCI > 20 at the time of surgery (p = 0.01). Five patients had delays in surgery due to the pandemic. Rates of overall postoperative morbidity, reoperation, and readmission were not different between the cohorts. Conclusions Despite presenting with more extensive disease, patients treated with CRS‐HIPEC during the height of the COVID‐19 pandemic had comparable perioperative outcomes to patients treated prepandemic.

Abstract
PURPOSE OF REVIEW Upper gastrointestinal bleeding (UGIB) has significant morbidity and UGIB cases have been described in coronavirus disease 2019 (COVID-19) patients. Management of this condition can be challenging considering both the possible severe COVID-19-related pneumonia as well as the risk of the virus spreading from patients to health operators. The aim of this paper is to review the most recent studies available in the literature in order to evaluate the actual incidence of UGIB, its clinical and endoscopic manifestations and its optimal management. RECENT FINDINGS UGIB has an incidence between 0.5% and 1.9% among COVID-19 patients, and it typically presents with melena or hematemesis. Peptic ulcers are the most common endoscopic findings. High Charlson Comorbidity Index (CCI), dialysis, acute kidney injury and advanced oncological disease increase the risk for UGIB. Although anticoagulants are commonly used in COVID-19 patients they are not associated with an increased incidence of UGIB. Conservative management is a common approach that results in similar outcomes compared to upper GI endoscopic treatment. Apparently, UGIB in COVID-19 seems not have a detrimental effect and only one study showed an increased mortality in those who developed UGIB during hospitalization. SUMMARY Incidence of UGIB in COVID-19 patients is similar to that of the general population. Despite the widespread use of anticoagulants in these patients, they are not associated with an increased risk of UGIB. Conservative management could be an effective option, especially for patients that are at risk of intubation.

Global prevalence of polypharmacy among the COVID-19 patients: a comprehensive systematic review and meta-analysis of observational studies. Trop Med Health 2022; 50:60. [PMID: 36042531 PMCID: PMC9427437 DOI: 10.1186/s41182-022-00456-x] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2022] [Accepted: 08/24/2022] [Indexed: 11/17/2022] Open
Abstract
Background Polypharmacy has traditionally been defined in various texts as the use of 5 or more chronic drugs, the use of inappropriate drugs, or drugs that are not clinically authorized. The aim of this study was to evaluate the prevalence of polypharmacy among the COVID-19 patients, and the side effects, by systematic review and meta-analysis. Methods This study was performed by systematic review method and in accordance with PRISMA 2020 criteria. The protocol in this work is registered in PROSPERO (CRD42021281552). Particular databases and repositories have been searched to identify and select relevant studies. The quality of articles was assessed based on the Newcastle–Ottawa Scale checklist. Heterogeneity of the studies was measured using the I2 test. Results The results of meta-analysis showed that the prevalence of polypharmacy in 14 studies with a sample size of 189,870 patients with COVID-19 is 34.6% (95% CI: 29.6–40). Studies have shown that polypharmacy is associated with side effects, increased morbidity and mortality among patients with COVID-19. The results of meta-regression analysis reported that with increasing age of COVID-19 patients, the prevalence of polypharmacy increases (p < 0.05). Discussion The most important strength of this study is the updated search to June 2022 and the use of all databases to increase the accuracy and sensitivity of the study. The most important limitation of this study is the lack of proper definition of polypharmacy in some studies and not mentioning the number of drugs used for patients in these studies. Conclusion Polypharmacy is seen in many patients with COVID-19. Since there is no definitive cure for COVID-19, the multiplicity of drugs used to treat this disease can affect the severity of the disease and its side effects as a result of drug interactions. This highlights the importance of controlling and managing prescription drugs for patients with COVID-19.

[PMID: 35472540 PMCID: PMC9020843 DOI: 10.1016/j.jhazmat.2022.128978] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/26/2022] [Revised: 04/09/2022] [Accepted: 04/18/2022] [Indexed: 05/07/2023]
Abstract
It has been frequently emphasized that highly contagious respiratory disease pathogens (such as SARS-CoV-2) are transmitted to the other hosts in the form of micro-sized aerosols (< 5 μm) in the air without physical contacts. Hospital environments such as negative-pressure unit are considered being consistently exposed to pathogens, so it is essential to quickly discharge them through the effective ventilation system. To achieve that, in the present study, we propose the optimized ventilation mechanism and design for the fastest removal of pathogen-laden aerosol using numerical simulations. We quantitatively evaluated the aerosol removal performance of various ventilation configurations (combinations of air exhaust and supply ducts), and found that the key mechanism is to form the coherent (preferentially upward) airflow structure to surround the respiratory flow containing the aerosol cluster. We believe that the present findings will play a critical role in developing the high-efficiency negative-pressure facility irrespective of its size and environments.

Abstract
BACKGROUND the COVID-19 pandemic has impacted on several aspects of health care services worldwide. The aim of the study was to determine its influence on the case volume, success rate and complication rate of endoscopic retrograde cholangiopancreatography (ERCP). METHOD all patients who underwent ERCP one-year before and after applying COVID-19 safety measures at the Qena University Hospital were included. Data were collected from the patients' records, analyzed and compared. RESULTS a total of 250 patients underwent ERCP between April 1st, 2019 and March 31st, 2021, and the mean age of participants was 52 ± 18 years. There was a 5 % increase in case volume after applying COVID-19 safety measures (128 vs 122) and the total procedure time was significantly shorter (42 vs 46 minutes, p = 0.04). There was no significant difference in the overall success rate and complication rate. Procedure success significantly correlated with cannulation attempts and total procedure time in both groups, and serum bilirubin and cannulation time in the pre-COVID-19 patients and alkaline phosphatase (ALP) in post-COVID patients. ERCP-related complications significantly correlated with cannulation attempts in both groups, and ALP, international normalized ratio (INR), cannulation time and total procedure time in pre-COVID-19 patients, and platelet count and amylase in post-COVID patients. Two patients were confirmed COVID-19 cases at the time of ERCP; therapeutic targets were achieved in both with a smooth post-ERCP recovery. Three out of nine ERCP team members caught a mild to moderate COVID-19 infection and recovered after receiving proper management. CONCLUSION our result show that there was no negative impact of using COVID-19 safety measures and precautions on the case-volume, indications, overall outcome or complication rate of ERCP.

Abstract
From many decades, emerging infections have threatened humanity. The pandemics caused by different CoVs have already claimed and will continue to claim millions of lives. The SARS, Ebola, MERS epidemics and the most recent emergence of COVID-19 pandemic have threatened populations across borders. Since a highly pathogenic CoV has been evolved into the human population in the twenty-first century known as SARS, scientific advancements and innovative methods to tackle these viruses have increased in order to improve response preparedness towards the unpredictable threat posed by these rapidly emerging pathogens. Recently published review articles on SARS-CoV-2 have mainly focused on its pathogenesis, epidemiology and available treatments. However, in this review, we have done a systematic comparison of all three CoVs i.e., SARS, MERS and SARS-CoV-2 along with Ebola and Zika in terms of their epidemiology, virology, clinical features and current treatment strategies. This review focuses on important emerging RNA viruses starting from Zika, Ebola and the CoVs which include SARS, MERS and SARS-CoV-2. Each of these viruses has been elaborated on the basis of their epidemiology, virulence, transmission and treatment. However, special attention has been given to SARS-CoV-2 and the disease caused by it i.e., COVID-19 due to current havoc caused worldwide. At the end, insights into the current understanding of the lessons learned from previous epidemics to combat emerging CoVs have been described. The travel-related viral spread, the unprecedented nosocomial outbreaks and the high case-fatality rates associated with these highly transmissible and pathogenic viruses highlight the need for new prophylactic and therapeutic actions which include but are not limited to clinical indicators, contact tracing, and laboratory investigations as important factors that need to be taken into account in order to arrive at the final conclusion.

The Effect of Covid-19 Pandemic on Current and Future Endoscopic Personal Protective Equipment Practices: A National Survey of 77 Endoscopists. J Can Assoc Gastroenterol 2022; 5:143-149. [PMID: 35669846 PMCID: PMC9157297 DOI: 10.1093/jcag/gwab045] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/08/2021] [Accepted: 12/09/2021] [Indexed: 11/16/2022] Open
Abstract
Introduction The COVID-19 pandemic has raised awareness about the importance of personal protective equipment (PPE). We aimed to study and compare PPE practices among Canadian endoscopists before and after the COVID-19 pandemic. Methods A 74-item questionnaire was emailed from June 2020 to September 2020 to practicing endoscopists in Canada. Survey questions collected basic demographics and differences between PPE practices pre- and post-COVID-19. PPE practices were categorized into four endoscopic procedure types including upper or lower endoscopy and diagnostic or interventional. Outcomes for specific procedures were reported as rates, with ranges shown when evaluating all procedure types together. Results A total of 77 respondents completed the survey with the majority of respondents aged 40 to 49 (44%) and identifying as Gastroenterologists (70%). Gender was evenly split (49% females versus 51% males). In the pre-pandemic era, the majority of endoscopists wore gowns (91 to 94%) and all endoscopists wore gloves (100%). However, the majority of endoscopists did not wear surgical masks (21 to 31%), face shields (13 to 34%), eye protection (13 to 21%), hair protection (11 to 13%), or N95 respirators (2 to 3%). In the post-pandemic era, more surgeons plan on wearing face shields (33 to 47%, P = 0.001 to 0.045), goggles (38.5 to 58.7%, P < 0.001), hair protection (33 to 36%, P = 0.011 to 0.024), and a trend suggests more surgeons will wear surgical masks (51 to 61%, P = 0.163 to 0.333). More endoscopists also plan on wearing N95 respirators during lower endoscopy (6 to 7%, P < 0.005). Conclusion The COVID-19 pandemic has changed the attitudes of many endoscopists regarding future PPE use in routine endoscopy. Ongoing studies are needed to inform new post-pandemic PPE consensus guidelines.

Abstract
Background and study aim: During the COVID-19 pandemic, the use of standard personal protective equipment (SPPE) reduces transmission risks during endoscopic procedures. Our aim was to assess the effect of enhanced personal protective equipment (EPPE) on colonoscopy performance and pain linked to the procedure compared with SPPE.
Patients and methods: During two similar periods with three- month duration (in 2019 and in 2020 during the COVID-19 pandemic), electronic medical records and colonoscopy reports were investigated for sequential patients undergoing colonoscopy. SPPE was used in 2019 and EPPE in 2020. The patients’ clinical data and information related to the procedure were collected and analyzed. Primary outcomes were the duration to intubate the cecum, total procedure duration and patient pain score at the end of the procedure. Secondary outcomes were adenoma detection rate (ADR), polyp detection rate (PDR) and cecal intubation rate (CIR).
Results: A total of 426 patients with colonoscopy performed were analyzed. The demographic features and indications for colonoscopy were similar for patients in both groups. The EPPE group had higher values for the parameters assessed as primary endpoints of cecal intubation time, withdrawal time, total procedure time and pain at the end of the procedure compared to the SPPE group and the differences were statistically significant. Conclusion: Our findings show that though the use of EPPE negatively affected colonoscopy performance and patient pain at the end of the procedure, it had no effect on the colonoscopy quality indices such as ADR, PDR and CIR.

Abstract
Nutritional support is essential in patients who have a limited capability to maintain their body weight. Therefore, oral feeding is the main approach for such patients. When physiological nutrition is not possible, positioning of a nasogastric, nasojejunal tube, or other percutaneous devices may be feasible alternatives. Creating a percutaneous endoscopic gastrostomy (PEG) is a suitable option to be evaluated for patients that need nutritional support for more than 4 wk. Many diseases require nutritional support by PEG, with neurological, oncological, and catabolic diseases being the most common. PEG can be performed endoscopically by various techniques, radiologically or surgically, with different outcomes and related adverse events (AEs). Moreover, some patients that need a PEG placement are fragile and are unable to express their will or sign a written informed consent. These conditions highlight many ethical problems that become difficult to manage as treatment progresses. The aim of this manuscript is to review all current endoscopic techniques for percutaneous access, their indications, postprocedural follow-up, and AEs.

Abstract
BACKGROUND Aim of the present report was to investigate the repercussions of COVID-19 pandemic on the procedural volumes and on the main indications of pediatric digestive endoscopy in Italy. METHODS An online survey was distributed at the beginning of December 2020 to Italian digestive endoscopy centers. Data were collected comparing two selected time intervals: the first from 1st of February 2019 to 30th June 2019 and the second from 1st February 2020 to 30th June 2020. RESULTS Responses to the survey came from 24 pediatric endoscopy Units. Globally, a reduction of 37.2% was observed between 2019 and 2020 periods with a significant decrease in median number of procedures (111 vs 57, p < 0.001). Both the median number of procedures performed for new diagnoses and those for follow-up purposes significantly decreased in 2020 (63 vs 36, p < 0.001 and 42 vs 21, p< 0.001, respectively). We reported a drastic reduction of procedures performed for suspected Celiac Disease and Functional Gastrointestinal Disorders (55.1% and 58.0%, respectively). Diagnostic endoscopies for suspected IBD decreased of 15.5%, whereas procedures for Mucosal Healing (MH) assessment reduced of 48.3%. CONCLUSIONS Our study provides real-world data outlining the meaningful impact of COVID-19 on pediatric endoscopy practice in Italy.

Abstract
The COVID-19 pandemic and infection control measures had an unavoidable impact on surgical services. During the first wave of the pandemic, elective surgery, endoscopy, and 'face-to-face' clinics were discontinued after recommendations from professional bodies. In addition, training courses, examinations, conferences, and training rotations were postponed or cancelled. Inadvertently, infection control and prevention measures, both within and outside hospitals, have caused a significant negative impact on training. At the same time, they have given space to new technologies, like telemedicine and platforms for webinars, to blossom. While the recovery phase is well underway in some parts of the world, most surgical services are not operating at full capacity. Unfortunately, some countries are still battling a second or third wave of the pandemic with severely negative consequences on surgical services. Several studies have looked into the impact of COVID-19 on surgical training. Here, an objective overview of studies from different parts of the world is presented. Also, evidence-based solutions are suggested for future surgical training interventions.

Abstract
The coronavirus disease 2019 (COVID-19) epidemic, which is caused by novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has continued to spread around the world since December 2019. Healthcare workers and other medical first responders in particular need personal protective equipment to protect their respiratory system from airborne particulates, in addition to liquid splashes to the face. N95 respirator have become a critical component for reducing SARS-CoV-2 transmission and controlling the scale of the COVID-19 pandemic. However, a major dispute concerning the protective performance of N95 respirators has erupted, with a myriad of healthcare workers affected despite wearing N95 masks. This article reviews the most recent updates about the performance of N95 respirators in protecting against the SARS-CoV-2 virus in the present pandemic situation. A brief overview of the manufacturing methods, air filtration mechanisms, stability, and reusability of the mask is provided. A detailed performance evaluation of the mask is studied from an engineering point of view. This Review also reports on a comparative study about the protective performance of all commercially available surgical and respiratory masks used to combat the spread of COVID-19. With the aim of protecting healthcare providers more efficiently, we suggest some potential directions for the development of this respiratory mask that improve the performance efficiency of the mask.

[PMID: 35303954 PMCID: PMC8931568 DOI: 10.1186/s40001-022-00672-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2020] [Accepted: 03/07/2022] [Indexed: 11/24/2022] Open
Abstract
BACKGROUND In response to the COVID-19 pandemic, endoscopic societies initially recommended reduction of endoscopic procedures. In particular non-urgent endoscopies should be postponed. However, this might lead to unnecessary delay in diagnosing gastrointestinal conditions. METHODS Retrospectively we analysed the gastrointestinal endoscopies performed at the Central Endoscopy Unit of Saarland University Medical Center during seven weeks from 23 March to 10 May 2020 and present our real-world single-centre experience with an individualized rtPCR-based pre-endoscopy SARS-CoV-2 testing strategy. We also present our experience with this strategy in 2021. RESULTS Altogether 359 gastrointestinal endoscopies were performed in the initial period. The testing strategy enabled us to conservatively handle endoscopy programme reduction (44% reduction as compared 2019) during the first wave of the COVID-19 pandemic. The results of COVID-19 rtPCR from nasopharyngeal swabs were available in 89% of patients prior to endoscopies. Apart from six patients with known COVID-19, all other tested patients were negative. The frequencies of endoscopic therapies and clinically significant findings did not differ between patients with or without SARS-CoV-2 tests. In 2021 we were able to unrestrictedly perform all requested endoscopic procedures (> 5000 procedures) by applying the rtPCR-based pre-endoscopy SARS-CoV-2 testing strategy, regardless of next waves of COVID-19. Only two out-patients (1893 out-patient procedures) were tested positive in the year 2021. CONCLUSION A structured pre-endoscopy SARS-CoV-2 testing strategy is feasible in the clinical routine of an endoscopy unit. rtPCR-based pre-endoscopy SARS-CoV-2 testing safely allowed unrestricted continuation of endoscopic procedures even in the presence of high incidence rates of COVID-19. Given the low frequency of positive tests, the absolute effect of pre-endoscopy testing on viral transmission may be low when FFP-2 masks are regularly used.

Abstract
Background: The COVID-19 outbreak has led IBD clinics to adopt a remote monitoring approach in order to guarantee an adequate follow-up of patients with inflammatory bowel disease (IBD) and ensure the rules of social distancing. Aim: The aim of the study was to perform a survey on IBD patients who underwent remote monitoring in our tertiary referral center, to assess adherence, patients’ perceptions and satisfaction, and finally their opinions for future monitoring. Furthermore, we evaluated changes in disease activity and Quality of Life (QoL) using validated questionnaires. Methods: Consecutive patients with IBD scheduled for follow-up visits were switched to remote monitoring through e-mail from March 2020 to February 2021. Patients were asked to complete a questionnaire focusing on the following elements of the intervention: (1) self-assessment questions, (2) action plans, and (3) educational messages. Results: Four hundred and twenty four Caucasian patients completed the survey. 233 (55.1%) were male, 220 (52.0%) had Crohn’s Disease (CD). Median baseline Mayo Score and Harvey Bradshaw Index were 3 and 4, respectively. 9 (2.1%) patients were referred to the emergency department because of disease flares. 410 (96.9%) patients were satisfied with telemedicine, and 320 (76.5%) patients reported that they would maintain this approach also after COVID-19 pandemic. Overall, on univariate logistic regression analysis, none of the variables were related to patients’ satisfaction or to an improved QoL. The presence of ulcerative colitis was associated with the need for treatment change. Conclusions: Our results suggest that a telemedicine approach is well accepted by patients with IBD and could represent an effective tool in monitoring disease activity. Further controlled studies are warranted to properly assess if telemedicine can replace face-to-face consultations in IBD.

Abstract
BACKGROUND/AIMS The Thai Association for Gastrointestinal Endoscopy published recommendations on safe endoscopy during the coronavirus disease 2019 (COVID-19) pandemic. This study aimed to assess the practicality and applicability of the recommendations and the perceptions of endoscopy personnel on them. METHODS A validated questionnaire was sent to 1290 endoscopy personnel globally. Of these, the data of all 330 responders (25.6%) from 15 countries, related to the current recommendations on proper personal protective equipment (PPE), case selection, scope cleaning, and safety perception, were analyzed. Ordinal logistic regression was used to determine the relationships between the variables. RESULTS Despite an overwhelming agreement with the recommendations on PPE (94.5%) and case selection (95.5%), their practicality and applicability on PPE recommendations and case selection were significantly lower (p=0.001, p=0.047, p<0.001, and p=0.032, respectively). Factors that were associated with lower sense of safety in endoscopy units were younger age (p=0.004), less working experience (p=0.008), in-training status (p=0.04), and higher national prevalence of COVID-19 (p=0.003). High prevalent countries also had more difficulty implementing the guidelines (p<0.001) and they considered the PPE recommendations less practical and showed lower agreement with them (p<0.001 and p=0.008, respectively). A higher number of in-hospital COVID-19 patients was associated with less agreement with PPE recommendations (p=0.039). CONCLUSION Using appropriate PPE and case selection in endoscopic practice during a pandemic remains a challenge. Resource availability and local prevalence are critical factors influencing the adoption of the current guidelines.
