Abstract Background: the 2019 novel coronavirus (COVID-19) is an emerging pandemic, with a disease course varying from asymptomatic infection to critical disease resulting to death. Recognition of prognostic factors is essential because of its growing prevalence and high clinical costs. This meta-analysis aimed to evaluate the global prevalence of obesity in COVID-19 patients and to investigate whether obesity is a risk factor for the COVID-19, COVID-19 severity, and its poor clinical outcomes including hospitalization, intensive care unit (ICU) admission, need for mechanical ventilation, and mortality.Methods: The study protocol was registered on to PROSPERO (CRD42020203386). A systematic search of Scopus, Medline, and Web of Sciences was conducted on June 2020, to find pertinent studies. After selection, 54 studies from 10 different countries were included in the quantitative analyses. Pooled odds ratios (OR) with 95% confidence intervals (CIs) were calculated to assess the associations. Results: The prevalence of obesity was 33% (95% CI, 30.0%–35.0%) among patients with COVID-19. Obesity was significantly associated with susceptibility to COVID-19 (OR=2.42, 95% CI: 1.58 to 3.70; moderate certainty) and COVID-19 severity (OR=1.62, 95% CI: 1.48 to 1.76; low certainty). Furthermore, obesity was a significant risk factor for hospitalization (OR=1.75, 95% CI: 1.47 to 2.09; very low certainty), mechanical ventilation (OR=2.24, 95% CI: 1.70 to 2.94; low certainty), intensive care unit (ICU) admission (OR=1.75, 95% CI: 1.38 to 2.22; low certainty), and death (OR=1.23, 95% CI: 1.06 to 1.41; low certainty) in COVID-19 patients. In the subgroup analyses, these associations were supported by the majority of subgroups. Conclusions: Obesity is associated with COVID-19 and its poor clinical outcomes. Thus, it is highly recommended to consider obesity status in prognostic scores and improvement of guidelines for the clinical care of patients with COVID-19.

Abstract Background: COVID-19 pneumonia seems to affect the regulation of pulmonary perfusion. In this study, through iodine distribution maps obtained with subtraction CT angiography, we quantified and analyzed perfusion abnormalities in patients with COVID-19 pneumonia and correlated them with clinical outcomes.Methods: 205 patients were included in this cohort, from two different tertiary-care hospitals in Chile. All patients had RT-PCR confirmed SARS-CoV-2 infection. CT scans were performed within 24 h of admission, in supine position. Airspace compromise was assessed with CT severity score, and the extension of hypoperfusion in apparently healthy lung parenchyma with perfusion score. CT severity and perfusion scores were then correlated with clinical outcomes. Multivariable analyses using Cox Proportional Hazards regression were used to control for clinical confounders.Results: Fourteen patients were excluded due to uninterpretable images. This left 191 patients, 112 males and 79 females. The mean age was 60.8±16.0 years. The median SOFA score on admission was 2 and average PaFi ratio was 250±118. Patients with severe perfusion abnormalities showed significantly higher SOFA scores and lower Pa/Fi ratios when compared to individuals with mild or moderate anomalies. Severe perfusion abnormalities were associated with an increased risk of intensive care unit (ICU) admission and the requirement of invasive mechanical ventilation (IMV).Conclusion: Patients with severe perfusion anomalies have a higher risk of admission to the ICU and IMV. Perfusion alterations could be considered as an independent risk factor in patients with COVID-19 pneumonia.Summary Statement: Lung perfusion abnormalities in patients with COVID-19 pneumonia were associated with admission to Intensive Care Unit and requirement of invasive mechanical ventilation. Perfusion abnormalities could be considered as an independent risk factor in patients with COVID-19 pneumonia.

Abstract Background Although several international guidelines recommend early over late intubation of patients with severe coronavirus disease 2019 (COVID-19), this issue is still controversial. We aimed to investigate the effect (if any) of timing of intubation on clinical outcomes of critically ill patients with COVID-19 by carrying out a systematic review and meta-analysis. Methods PubMed and Scopus were systematically searched, while references and preprint servers were explored, for relevant articles up to December 26, 2020, to identify studies which reported on mortality and/or morbidity of patients with COVID-19 undergoing early versus late intubation. “Early” was defined as intubation within 24 h from intensive care unit (ICU) admission, while “late” as intubation at any time after 24 h of ICU admission. All-cause mortality and duration of mechanical ventilation (MV) were the primary outcomes of the meta-analysis. Pooled risk ratio (RR), pooled mean difference (MD) and 95% confidence intervals (CI) were calculated using a random effects model. The meta-analysis was registered with PROSPERO (CRD42020222147). Results A total of 12 studies, involving 8944 critically ill patients with COVID-19, were included. There was no statistically detectable difference on all-cause mortality between patients undergoing early versus late intubation (3981 deaths; 45.4% versus 39.1%; RR 1.07, 95% CI 0.99–1.15, p = 0.08). This was also the case for duration of MV (1892 patients; MD − 0.58 days, 95% CI − 3.06 to 1.89 days, p = 0.65). In a sensitivity analysis using an alternate definition of early/late intubation, intubation without versus with a prior trial of high-flow nasal cannula or noninvasive mechanical ventilation was still not associated with a statistically detectable difference on all-cause mortality (1128 deaths; 48.9% versus 42.5%; RR 1.11, 95% CI 0.99–1.25, p = 0.08). Conclusions The synthesized evidence suggests that timing of intubation may have no effect on mortality and morbidity of critically ill patients with COVID-19. These results might justify a wait-and-see approach, which may lead to fewer intubations. Relevant guidelines may therefore need to be updated.

Candidemia is becoming more actual because of better survival of even critically ill patients, wide use of antimicrobials, and increased numbers of invasive procedures and manipulations. Diagnosis of candidemia remains complicated, and costs of treatment and mortality rates are increasing. Objective. To evaluate the pathogens of candidemia, risk factors and their influence on outcome. Material and methods. Data of 41 patients with positive blood culture for Candida spp., who were treated in the intensive care units at the Hospital of Kaunas University of Medicine, were analyzed retrospectively. Results. Candidemia was caused by Candida albicans (C. albicans) in 48.8% (n=20) of patients and by non-albicans Candida in 51.2% (n=21) of patients. The main cause of candidemia was C. albicans in 2004 (83.3%, n=5), but in 2005 (63.6%, n=7), in 2006 (57.1%, n=4), and in 2007 (52.9%, n=9), the main cause was non-albicans Candida spp. The number of candidemia cases caused by C. albicans was decreased in 2005, 2006, and 2007 as compared with 2004, and the number of candidemia caused by non-albicans Candida spp. was decreased, respectively (P<0.05). More than 65% (n=34) of patients had severe disease (P<0.05). Lethal outcome was recorded in 58.5% of patients with candidemia. Mechanical ventilation was used in 76.9% (n=20) and urinary bladder catheter in 72.1% (n=19) of non-survivors and in 23.1% (n=6) and 26.9% (n=7) of survivors, respectively (P<0.05). Conclusions. There is an increase in the prevalence of candidemia in the intensive care units during the 4-year period; half of candidemia cases were caused by non-albicans Candida spp., and patients with candidemia caused by non-albicans Candida spp. are at higher risk of mortality. Therefore, for the empirical treatment of septic conditions in an intensive care unit, when invasive fungal infection is suspected, we recommend using an antifungal agent of non-azole class until a pathogen of candidemia is determined. Severe disease is evaluated as a risk factor for candidemia. Patients with oncological diseases are at significantly higher risk for candidemia caused by non-albicans Candida spp. Use of mechanical ventilation and urinary bladder catheter is a risk factor for lethal outcome.

AbstractImportanceOn 11th March, the World Health Organization declared a pandemic of COVID-19. There are over 1 million cases around the world with this disease and it continues to raise. Studies on COVID-19 patients have reported high rate of cardiovascular disease (CVD) among them and patients with CVD had higher mortality rate.ObjectivesSince there were controversies between different studies about CVD burden in COVID-19 patients, we aimed to study cardiovascular disease burden among COVID-19 patients using a systematic review and meta-analysis.Data SourcesWe have systematically searched databases including PubMed, Embase, Cochrane Library, Scopus, Web of Science as well as medRxiv pre-print database. Hand searched was also conducted in journal websites and Google Scholar.Study SelectionStudies reported cardiovascular disease among hospitalized adult COVID-19 patients with mortality or ICU admission (primary outcomes) were included into meta-analysis. In addition, all of studies which reported any cardiovascular implication were included for descriptive meta-analysis. Cohort studies, case-control, cross-sectional, case-cohort and case series studies included into the study. Finally, 16 studies met the inclusion criteria for primary outcome and 59 studies for descriptive outcome.Data Extraction and SynthesisTwo investigators have independently evaluated quality of publications and extracted data from included papers. In case of disagreement a supervisor solved the issue and made the final decision. Quality assessment of studies was done using Newcastle-Ottawa Scale tool. Heterogeneity was assessed using I-squared test and in case of high heterogeneity (>%50) random effect model was used.Main Outcomes and MeasuresMeta-analyses were carried out for Odds Ratio (OR) of mortality and Intensive Care Unit (ICU) admission for different CVDs and Standardized Mean Difference (SMD) was calculated for Cardiac Troponin I. We have also performed a descriptive meta-analysis on different CVDs.ResultsSixteen papers including 3473 patients entered into meta-analysis for ICU admission and mortality outcome and fifty-nine papers including 9509 patients for descriptive outcomes. Results of meta-analysis indicated that acute cardiac injury, (OR: 15.94, 95% CI 2.31-110.14), hypertension (OR: 1.92, 95% CI 1.92-2.74), heart Failure (OR: 11.73, 95% CI 5.17-26.60), other cardiovascular disease (OR: 1.95, 95% CI 1.17-3.24) and overall CVDs (OR: 3.37, 95% CI 2.06-5.52) were significantly associated with mortality in COVID-19 patients. Arrhythmia (OR: 22.17, 95%CI 4.47-110.04), acute cardiac injury (OR: 19.83, 95%CI 7.85-50.13), coronary heart disease (OR: 4.19, 95%CI 1.27-13.80), cardiovascular disease (OR: 4.17, 95%CI 2.52-6.88) and hypertension (OR: 2.69, 95%CI 1.55-4.67) were also significantly associated with ICU admission in COVID-19 patients.ConclusionOur findings showed a high burden of CVDs among COVID-19 patients which was significantly associated with mortality and ICU admission. Proper management of CVD patients with COVID-19 and monitoring COVID-19 patients for acute cardiac conditions is highly recommended to prevent mortality and critical situations.Key PointsQuestionAre cardiovascular disease associated with mortality and Intensive Care Unit admission (ICU) of COVID-19 patients?FindingsIn this systematic review and meta-analysis, acute cardiac injury, hypertension, heart failure and overall cardiovascular diseases were significantly associated with mortality in COVID-19 patients. Arrhythmia, coronary heart disease, hypertension, acute cardiac injury and other cardiovascular disease were significantly associated with ICU admission of COVID-19 patients.MeaningCardiovascular diseases have significant role in mortality and disease severity of COVID-19 patients. COVID-19 patients need to be carefully monitored for cardiovascular diseases and managed properly in case of acute cardiac conditions.

Abstract Since the outbreak of COVID-19 several studies conducted to identify predictive factors which are associated with prognosis of COVID-19. In this study we aimed to determine whether the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) could help the clinicians to predict intensive care unit (ICU) admission and mortality of COVID-19 patients. This retrospective cohort study involved examining the medical records of 311 Iranian COVID-19 patients from 22 July 2020 to 22 August 2020. All characteristic data and laboratory results were recorded. The receiver operating characteristic (ROC) curve was used to identify the predictive value of studied parameters for ICU admission and death. Comparison of data revealed that some factors were jointly higher in non-survivors and ICU admitted patients than survivors and non-ICU admitted patients, such as: age, hemoglobin (HB), NLR, derived neutrophil-to-lymphocyte ratio (dNLR), PLR, systemic inflammatory index (SII), lactate dehydrogenase (LDH), Respiratory diseases, ischemic heart disease (IHD). Multivariate logistic regression analysis showed that only hypertension (OR 3.18, P=0.02) is an independent risk factor of death in COVID-19 patients, and also PLR (OR 1.02, P=0.05), hypertension (OR 4.00, P=0.002) and IHD (OR 5.15, P=0.008) were independent risk factor of ICU admission in COVID-19 patients. This study revealed that the NLR, PLR, platelet-to-white blood Cell ratio (PWR), dNLR and SII are valuable factors for predicting ICU admission and mortality of COVID-19 patients.

Emerging evidence shows that the recent pandemic of coronavirus disease 19 (COVID-19) is characterized by coagulation activation and endothelial dysfunction. This increases the risk of morbidity, mortality and economic loss among COVID-19 patients. Therefore, there was an urgent need to investigate the extent and risk factors of thromboembolism among COVID-19 patients. English-language based databases (PubMed, Cumulative Index to Nursing and Allied Health Literature, EMBASE, and Cochrane library) were exhaustively searched to identify studies related to prevalence of thromboembolism among hospitalized COVID-19 patients. A random-effects model was employed to estimate the pooled prevalence of thromboembolism. The pooled prevalence of thrombotic events was computed using STATA 16.0 software. Heterogeneity analysis was reported using I2. A total of 19 studies with 2,520 patients with COVID-19 were included. The pooled prevalence of thrombotic events of hospitalized patients with COVID-19 was 33% (95% CI: 25-41%, I2 = 97.30%, p < 0.001) with a high degree of heterogeneity across studies. Elevated D-dimer hospitalized in the intensive care unit and being under mechanical ventilation were the most frequently associated factors for the development of thrombotic events. The pooled prevalence of thrombotic events in COVID-19 patients was 33%. The prevalence of thrombotic event is variables on the basis of study design and study centers. Several risk factors such as, elevated D-dimer, hospitalized in the intensive care unit and being under mechanical ventilation, were the most frequently reported risk factors identified. Therefore, healthcare professionals should consider these risk factors to optimally manage thromboembolism in COVID-19 patients.

Background: Redo coronary artery bypass grafting (redo CABG) is associated with increased mortality and morbidity. The aim of this study was to systematically evaluate the evidence comparing the outcomes of off-pump with on-pump redo CABG. Methods: Studies were systematically searched and identified using PubMed, EMBASE, the Cochrane Library, and the International Clinical Trials Registry Platform (ICTRP) by two researchers independently. The primary outcome was 30-day mortality, and the secondary outcomes were in-hospital mortality, post-operative complications, completeness of revascularization, blood transfusion rate, duration of mechanical ventilation, intensive care unit and hospital stays. Results: The 21 studies including 4,889 patients were enrolled in our meta-analysis. Compared with on-pump, the off-pump technique was associated with significantly reduced 30-day mortality (odds ratio [OR] = 0.43, 95% confidence interval [CI] = 0.26-0.72, p = 0.001). Moreover, a notably decreased in-hospital mortality (OR = 0.55, 95% CI = 0.39-0.76, p = 0.0004) and incidence of post-operative new-onset atrial fibrillation, myocardial infarction, acute kidney injury, low cardiac output state, blood transfusion rate (OR = 0.46, 95% CI = 0.35-0.60, p < 0.00001; OR = 0.54, 95% CI = 0.38-0.78, p = 0.0007; OR = 0.51, 95% CI = 0.37-0.70, p < 0.0001; OR = 0.31, 95% CI = 0.20-0.47, p < 0.00001; OR = 0.29, 95% CI = 0.14-0.61, p = 0.001) and significantly shortened duration of mechanical ventilation, intensive care unit and hospital stays (mean difference [MD] = −8.21 h, 95% CI = −11.74 to −4.68, p < 0.00001; MD = −0.77 d, 95% CI = −0.81 to −0.73, p < 0.00001; MD = −2.24 d, 95% CI = −3.17 to −1.32, p < 0.00001) could be observed when comparing the outcomes of off-pump with on-pump redo CABG. There was nonsignificant difference between off-pump and on-pump redo CABG in completeness of revascularization. Conclusion: In patients undergoing redo CABG surgery, the off-pump technique was associated with decreased mortality, less post-operative complications when compared to on-pump.
