RESUMO
Over 17.7 million gastrointestinal (GI) endoscopic procedures are performed annually, contributing to 68% of all endoscopic procedures in the United States. Usually, endoscopic procedures are low risk, but adverse events may occur, including cardiopulmonary complications, bleeding, perforation, pancreatitis, cholangitis, and infection. Infections after the GI endoscopies most commonly result from the patient's endogenous gut flora. Although many studies have reported infection after GI endoscopic procedures, a true estimate of the incidence rate of post-endoscopy infection is lacking. In addition, the infection profile and causative organisms have evolved over time. In recent times, multi-drug-resistant microorganisms have emerged as a cause of outbreaks of endoscope-associated infections (EAI). In addition, lapses in endoscope reprocessing have been reported, with some but not all outbreaks in recent times. This systematic review summarizes the demographical, clinical, and management data of EAI events reported in the literature. A total of 117 articles were included in the systematic review, with the majority reported from North America and Western Europe. The composite infection rate was calculated to be 0.2% following GI endoscopic procedures, 0.8% following ERCP, 0.123% following non-ERCP upper GI endoscopic procedures, and 0.073% following lower GI endoscopic procedures. Pseudomonas aeruginosa was the most common culprit organism, followed by other Enterobacteriaceae groups of organisms and Gram-positive cocci. We have also elaborated different prevention methods such as antimicrobial prophylaxis, adequate sterilization methods for reprocessing endoscopes, periodic surveillance, and current evidence supporting their utilization. Finally, we discuss disposable endoscopes, which could be an alternative to reprocessing to minimize the chances of EAIs with their effects on the environmental and financial situation.

BACKGROUND/OBJECTIVES: SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), first described in December 2019, has infected more than 33 million people and claimed more than 1 million deaths worldwide. Rheumatic diseases are chronic inflammatory diseases, the prevalence and impact of which in COVID-19 patients are poorly known. We performed a pooled analysis of published data intending to summarize clinical presentation and patient outcomes in those with established rheumatic disease diagnosis and concurrent COVID-19. METHODS: PubMed and Google Scholar were searched to identify studies reporting data about rheumatic disease patients who were diagnosed with SARS-CoV-2 infection and published until July 22, 2020. Random-effects models were used to estimate the pooled incidence and rates of hospitalization, intensive care unit admission, and mortality among these patients, and interstudy heterogeneity was identified using I2 statistics with greater than 75% value indicating substantial interstudy variation. RESULTS: Twenty studies were included, giving a total sample size of 49,099 patients positive for SARS-CoV-2. Of 49,099 COVID-19 patients, a total of 1382 were also diagnosed with a rheumatic disease in the past. The random-effects pooled prevalence of COVID-19 among rheumatic disease patients was found to be 0.9%. The rates of hospitalization, intensive care unit admission, and mortality were 70.7%, 11.6%, and 10.2%, respectively. CONCLUSIONS: Although the prevalence of SARS-CoV-2 infection is not dramatically high in rheumatic disease patients, concurrent COVID-19 does seem to play a role in determining disease severity and outcomes to some extent. Further studies are needed to give conclusive evidence about whether this subset of the population is at a higher risk of COVID-19 and related outcomes compared with the population at large.

BACKGROUND: Aortic valve myxoma is the rarest location of the most common primary tumour of cardiac origin. Because of the paucity of data, there is little known about their clinical presentation, diagnosis and complications. METHODS: PUBMED, EMBASE, SCOPUS and WEB OF SCIENCE were systematically searched to identify all published cases of aortic valve myxoma through October 2020. Descriptive statistics were used to report the data. RESULTS: Aortic valve myxomas were more prevalent in young (mean age 41 years) male (75%) patients. It most commonly involved the right coronary cusp (50%). Cerebrovascular events (25%), dyspnoea (18.8%), and distal embolisation (18.8%) were found to be the most frequent complications. Echocardiography remains the diagnostic modality of choice in all cases, histopathology is used for confirmation. Most cases were treated with surgical excision (94%); concomitant aortic valve repair and mechanical aortic valve replacement were performed in 25% and 37.5% cases respectively. Sudden cardiac death was noted in one patient. CONCLUSION: Aortic valve myxomas are more often than not discovered in the context of embolic phenomenon or dyspnoea. The most feared complication is stroke, although mortality remains low in surgically managed cases.

Coronavirus disease 2019 (COVID-19), causes serious respiratory illness manifesting as pneumonia, adult respiratory distress syndrome and respiratory failure. Amidst the rising number of cases and deaths, it is imperative to not forget Tuberculosis (TB) which is another pandemic existing since centuries. There could be dire consequences for tuberculosis patients globally especially in low and middle income countries with a high burden of disease and overwhelmed health care systems. Tuberculosis is still the leading infectious killer worldwide, and therefore, it is crucial to reflect on the interaction between the two diseases. Evidence suggests that both COVID-19 and tuberculosis have a synergistic relationship, boosting detrimental effect of each other, disrupting existing health care models, and also worsening the clinical outcomes in terms of morbidity and mortality. This review aims to draw attention towards this pertinent clinical issue, and tries to unravel the intricate relationship between COVID-19 and tuberculosis, as also the role of BCG vaccination to combat the COVID-19 pandemic.

RESUMO
BACKGROUND: Comparison of the real-world cohort on the relative safety of alcohol septal ablation (ASA) vs. septal myectomy (SM) for the management of hypertrophic cardiomyopathy (HCM) has been lacking. METHODS: The National Inpatient Sample (NIS) (2012-2019) was used to select all cases of HCM. The safety of ASA vs. SM was compared using a one:many propensity score matched (PSM) analysis. Adjusted odds ratios (aOR) for mortality and other in-hospital complications were computed. RESULTS: A total of 6208 HCM patients (ASA 3106 vs. SM 3102) were included using a PSM analysis. Post-procedural bleeding (aOR 0.18, 95 % CI 0.11-0.32, p < 0.0001) and the need for an intra-aortic balloon pump (aOR 0.51, 95 % CI, 0.28-0.96, p = 0.037) were significantly lower while permanent pacemaker (PPM) implantation was significantly higher in ASA group as compared with SM group (aOR 1.72, 95 % CI, 1.43-2.06, p < 0.0001). The total in-hospital mean adjusted cost and length of stay were also significantly lower in the ASA group. However, there were no significant differences in adjusted odds of all-cause mortality (aOR 0.91, 95 % CI 0.62-1.33, p = 0.61), stroke (aOR 0.91, 95 % CI, 0.59-1.4, p = 0.66), and major bleeding (aOR 1.0, 95 % CI 7.8-1.29, p = 0.99) between the two comparison groups. CONCLUSION: In patients with hypertrophic cardiomyopathy, alcohol septal ablation appears to be an acceptable alternative to septal myectomy due to a lower risk of post-procedural bleeding and the need for an intra-aortic balloon pump. However, ASA confers a higher risk of PPM placement.

Background and study aims Post-ERCP pancreatitis (PEP) is the most common complication attributed to the procedure, its incidence being approximately 9.7â%. Numerous studies have evaluated the predictive efficacy of post-procedure serum amylase and lipase levels but with varied procedure-to-test time intervals and cut-off values. The aim of this meta-analysis was to present pooled data from available studies to compare the predictive accuracies of serum amylase and lipase for PEP. Patients and methods A total of 18 studies were identified after a comprehensive search of various databases until June 2021 that reported the use of pancreatic enzymes for PEP. Results The sample size consisted of 11,790 ERCPs, of which PEP occurred in 764 (6.48â%). Subgroups for serum lipase and amylase were created based on the cut-off used for diagnosing PEP, and meta-analysis was done for each subgroup. Results showed that serum lipase more than three to four times the upper limit of normal (ULN) performed within 2 to 4 hours of ERCP had the highest pooled sensitivity (92â%) for PEP. Amylase level more than five to six times the ULN was the most specific serum marker with a pooled specificity of 93â%. Conclusions Our analysis indicates that a lipase level less than three times the ULN within 2 to 4 hours of ERCP can be used as a good predictor to rule out PEP when used as an adjunct to patient clinical presentation. Multicenter randomized controlled trials using lipase and amylase are warranted to further evaluate their PEP predictive accuracy, especially in high-risk patients.
RESUMO
Background Obstructive sleep apnea (OSA) is often present in coronary artery disease patients and confers a high risk of complications following percutaneous coronary interventions (PCI). The impact of two commonly associated comorbid conditions, chronic obstructive pulmonary disease (COPD) and obesity hypoventilation syndrome (OHS, Pickwickian syndrome) in OSA patients undergoing PCI has never been studied. Methods The National Inpatient Sample (NIS; 2007-2014) was queried using the International Classification of Diseases, Clinical Modification 9 (ICD-9-CM) codes to compare baseline characteristics, comorbidities, and outcomes in adults undergoing PCI with OSA, COPD-overlap syndrome, and OSA+OHS. Results Of a total of 4,792,177 PCI-related inpatient encounters, OSA, OSA-COPD overlap syndrome, and OSA+OHS were found to be present in 153,706 (median age 62 years, 79.4% male), 65135 (median age 65 years, 66.0% male), and 2291 (median age 63 years, 58.2% males) patients, respectively. The OHS+OSA cohort, when compared to the COPD-OSA and OSA cohorts, was found to have the worst outcomes in terms of all-cause mortality (2.8% vs. 1.5% vs. 1.1%), hospital stay (median 6 vs. 3 vs. 2 days), hospital charges ($147, 209 vs. $101,416 vs. $87,983). Complications, including cardiogenic shock (7.3% vs. 3.4% vs. 2.6%), post-procedural myocardial infarction (11.2% vs. 7.1% vs. 6.0%), iatrogenic cardiac complications (6.1% vs. 3.5% vs. 3.7%), respiratory failure, acute kidney injury, infections, and pulmonary embolism, were also significantly higher in patients with OHS+OSA. Adjusted multivariable analysis revealed equivalent results with OHS+OSA having worse outcomes than OSA-COPD and OSA. Conclusion Concomitant OHS and COPD were linked to worse clinical outcomes in patients with OSA undergoing PCI. Future prospective studies are warranted to fully understand related pathophysiology, evaluate and validate long-term outcomes, and formulate effective preventive and management strategies.
RESUMO
Despite the lack of direct evidence that hypertension increases the likelihood of new infections, hypertension is known to be the most common comorbid condition in COVID-19 patients and also a major risk factor for severe COVID-19 infection. The literature review suggests that data is heterogeneous in terms of the association of hypertension with mortality. Hence, it remains a topic of interest whether hypertension is associated with COVID-19 disease severity and mortality. Herein, we perform a multicenter retrospective analysis to study hypertension as an independent risk for in-hospital mortality in hospitalized COVID-19 patients. This multicenter retrospective analysis included 515 COVID-19 patients hospitalized from March 1, 2020 to May 31, 2020. Patients were divided into two groups: hypertensive and normotensive. Demographic characteristics and laboratory data were collected, and in-hospital mortality was calculated in both groups. The overall mortality of the study population was 25.3% (130 of 514 patients) with 96 (73.8%) being hypertensive and 34 (26.2%) being normotensive (p-value of 0.01, statistically non-significant association). The mortality rate among the hypertensive was higher as compared to non-hypertensive; however, hypertensive patients were more likely to be old and have underlying comorbidities including obesity, diabetes mellitus, coronary artery disease, congestive heart failure, stroke, chronic kidney disease (CKD), chronic obstructive pulmonary disease (COPD), and cancer. Therefore, multivariable logistic regression failed to show any significant association between hypertension and COVID-19 mortality. To our knowledge, few studies have shown an association between hypertension and COVID-19 mortality after adjusting confounding variables. Our study provides further evidence that hypertension is not an independent risk factor for in-hospital mortality when adjusted for other comorbidities in hospitalized COVID-19 patients.
RESUMO
Gastrointestinal (GI) cancers, including esophageal, gastric, colorectal, liver, and pancreatic cancers, remain as one of the leading causes of death worldwide, with a large proportion accounting for fatalities related to metastatic disease. Invasion of primary cancer occurs by the actin cytoskeleton remodeling, including the formation of the filopodia, stereocilia, and other finger-like membrane protrusions. The crucial step of actin remodeling in the malignant cells is mediated by the fascin protein family, with fascin-1 being the most active. Fascin-1 is an actin-binding protein that cross-links filamentous actin into tightly packed parallel bundles, giving rise to finger-like cell protrusions, thus equipping the cell with the machinery necessary for adhesion, motility, and invasion. Thus, fascin-1 has been noted to be a key component for determining patient diagnosis and treatment plan. Indeed, the overexpression of fascin-1 in GI tract cancers has been associated with a poor clinical prognosis and metastatic progression. Moreover, fascin-1 has received attention as a potential therapeutic target for metastatic GI tract cancers. In this review, we provide an up-to-date literature review of the role of fascin-1 in the initiation of GI tract cancers, metastatic progression, and patients' clinical outcomes.
RESUMO
Sodium-glucose cotransporter-2 (SGLT2) inhibitors assert their role as an anti-diabetic medication by reversibly inhibiting sodium-glucose cotransporters in the renal proximal tubules and resulting in enhanced glucose excretion. Due to their reversible effect on the transporters in the proximal tubule, it is expected that all their metabolic effects, including glucose excretion, should also cease in two to three days, as per their half-life of 10-15 hours. However, it is increasingly being observed that the glycosuric effect of SGLT2 inhibitors persists beyond this duration and, in many cases, exceeds their other known metabolic effects, which resolve sooner. We present a case report of a 53-year-old diabetic male who developed SGLT2 inhibitor-related euglycemic diabetic ketoacidosis (EuDKA) two days after being discharged post a laparoscopic appendectomy procedure. The patient was treated as per the recommended protocols, after which ongoing metabolic acidosis abated, but the patient's urinary glucose remained on the higher end. We present an up-to-date review of existing evidence on this rare but serious side effect of SGLT2 inhibitors.
RESUMO
The earliest evidence from China suggested that COVID-19 patients are even more vulnerable to succumbing from complications in the presence of a multimorbid status, including metabolic syndrome. Due to ongoing metabolic abnormalities, non-alcoholic fatty liver disease (NAFLD) appears to be a potential risk factor for contracting SARS-CoV-2 infection and developing related complications. This is because of the interplay of chronically active inflammatory pathways in NAFLD- and COVID-19-associated acute cytokine storm. The risk of severe disease could also be attributed to compromised liver function as a result of NAFLD. We systematically reviewed current literature to ascertain the relationship between NAFLD and severe COVID-19, independent of obesity, which is considered the major factor risk factor for both NAFLD and COVID-19. We found that NAFLD is a predictor of severe COVID-19, even after adjusting for the presence of obesity (OR 2.358; 95% CI: 1.902-2.923, p < 0.001).
RESUMO
In the latter part of 2019, a cluster of unexplained pneumonia cases were reported in Wuhan, China. In less than a year, SARS-CoV-2 has infected over 27 million people and claimed more than 800,000 deaths worldwide. Diabetes is a highly prevalent chronic metabolic disease, and recent reports have suggested a possible existence of COVID-19 related new-onset diabetes. Hyperglycemia induces an inflammatory state in the body, which coupled with coronavirus associated immune response is a possible explanation for clinical worsening of patients. We present a summary and pooled analysis of available evidence to ascertain the relationship between hyperglycemia in undiagnosed diabetics and outcomes of COVID-19 disease. Our results showed that hyperglycemia in non-diabetics was associated with higher risk of severe/critical illness (OR 1.837 (95% CI 1.368-2.465, P < 0.001) and mortality (2.822, 95% CI 1.587-5.019, P < 0.001) compared with those with normal values of blood glucose. The management of hyperglycemia in COVID-19 poses significant challenges in clinical practice, and the need to develop strategies for optimal glucose control in these patients cannot be overlooked.
RESUMO
OBJECTIVE: The objective of this study was to evaluate the pooled estimate of diabetes prevalence in young (<50 years) versus elderly (>50 years) COVID-19 cohorts. METHODS: Studies published between December-2019 and March-2020 reporting demographic and clinical characteristics of COVID-19 cases were identified. A total of 11 studies included accounting for 2084 COVID-19 patients. RESULTS: The overall prevalence of diabetes in COVID-19 patients with a mean age>50 years was 13.2%, whereas studies with relatively younger patients (mean age <50 years) had a pooled prevalence of 9.0% CONCLUSION: The overall prevalence of diabetes in COVID-19 patients was found to be 13.2% with studies including relatively elderly patients showing higher rates of diabetes. The intermingled effects of diabetes with other cardiovascular comorbidities warrant age-specific outcomes data including the impact of ongoing antidiabetic treatment.

Introduction The current coronavirus disease 19 (COVID-19) outbreak has been declared to be a pandemic by the World Health Organization (WHO). It is evolving daily and has jeopardized life globally across social and economic fronts. One of the six key strategic objectives identified by the WHO to manage COVID-19 is to communicate critical information to all communities and prevent the spread of misinformation. We analyzed content on YouTube.com, a widely used web-based platform for medical and epidemiological information. Methods YouTube search results using two keywords were analyzed each in six languages - English, Arabic, Bengali, Dutch, Hindi, and Nigerian Pidgin on April 8, 2020. Forty videos in each of the six languages (i.e., a total of 240 videos) were included for analysis in the study. Two reviewers conducted independent analyses for each language. The inter-observer agreement was evaluated with the kappa coefficient (κ). Modified DISCERN index and Medical Information and Content Index (MICI) scores were used for the reliability of content presented in the videos and information quality assessment, respectively. Analysis of variance, Kruskal-Wallis, Mann-Whitney test, and chi-square tests were done appropriately for data analysis. A p-value of less than 0.05 was considered statistically significant. All calculations were performed using SPSS Statistics for Windows, Version 21.0 (IBM Corp, Armonk, NY). Results The videos cumulatively attracted 364,080,193 views. Altogether, 52.5% of videos were Informative, 23.75% were News Updates, and 8.33% were Personal Experiences. Ten percent of videos were found to present medically misleading information. Independent Users contributed 75% of the misleading content. The overall Mean DISCERN score, an index of content reliability, was 2.62/5. The overall Mean MICI Score was 5.68/25. Videos had better scores in the Transmission component of the MICI scale and scored low on the Screening/Testing component. Conclusion The reliability and quality of the content of most videos about COVID-19 and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) were found to be unsatisfactory. Videos with misleading content were found across all six languages, and sometimes garnered a higher percentage of views than those from credible sources. The share of videos contributed by Government and Health Agencies was low. Medical institutions and health agencies should produce content on widely used platforms like YouTube for quality medical and epidemiological information dissemination.
RESUMO
There remains a high risk of thrombosis in patients affected by the SARS-CoV-2 virus and recent reports have shown pulmonary embolism (PE) as a cause of sudden death in these patients. However, the pooled rate of this deadly and frequently underdiagnosed condition among COVID-19 patients remains largely unknown. Given the frequency with which pulmonary embolism has been reported as a fatal complication of severe coronavirus disease, we sought to ascertain the actual prevalence of this event in COVID-19 patients. Using PubMed/Medline, EMBASE, and SCOPUS, a thorough literature search was performed to identify the studies reporting rate of PE among COVID-19. Random effects models were obtained to perform a meta-analysis, and I 2 statistics were used to measure inter-study heterogeneity. Among 3066 COVID-19 patients included from 9 studies, the pooled prevalence of PE was 15.8% (95% CI (6.0-28.8%), I 2 = 98%). The pooled rate in younger cohort (age < 65 years) showed a higher prevalence of 20.5% (95% CI (17.6-24.8%)) as compared to studies including relatively older cohort (age > 65 years) showing 14.3% (95% CI (2.9-30.1%)) (p < 0.05). Single-center studies showed a prevalence of 12.9% (95% CI 1.0-30.2%), while that of multicenter studies was 19.5% (95% CI 14.9-25.2%) (p < 0.05). Pulmonary embolism is a common complication of severe coronavirus disease and a high degree of clinical suspicion for its diagnosis should be maintained in critically ill patients.
RESUMO
The severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2), the causative agent of the novel coronavirus disease 2019 (COVID 19), was reported to the World Health Organization in late 2019. This disease quickly evolved into a public health concern and was declared a pandemic on March 11, 2020. COVID-19's high transmission rate and potential to cause a spectrum of systemic diseases makes it imperative for researchers and clinicians worldwide to collaborate and develop a strategy to manage and contain this disease. Studies have shown a wide range of hematological abnormalities and virus-related coagulopathies in affected patients, resulting in an increased propensity to develop serious thrombotic complications or disseminated intravascular coagulation (DIC) in severe cases. The fatal implications of coagulopathy in the form of pulmonary embolism (PE), myocardial infarction (MI), and cerebral infarction compelled us to study in-depth the pathophysiology and treatment options related to COVID-19. This analysis reviews published reports on patients with confirmed SARS-COV-2 infection and associated coagulopathy, defined as abnormalities in the coagulation parameters prothrombin time (PT), activated partial thromboplastin time (aPTT), antithrombin time, fibrinogen, fibrin degradation products, and D-dimer. In this review, we present the hematological manifestations of COVID-19, focusing on virus-associated coagulopathy and relevant pathophysiology, clinical outcomes, and treatment.
