Fear of COVID-19 scale: Psychometric properties,reliability and validity in Egyptian population

Background and aimsThe primary purpose of this study is to examine the psychometric qualities of the Fear of COVID-19 Scale (FCV–19S) in a sample of Egyptian college students. The researchers also aim at exploring the construct validity further through examining the relationship between FCV-19S, wellbeing and life satisfaction in Egyptian universities context. The current study aims to evaluate the psychometric properties of the Arabic version of the Fear of COVID-19 scale among Egyptian population.MethodsThe FCV-19S is translated and validated in Egyptian context. The forward backward translation method is used to translate the English version of the survey into Arabic. The sample is comprised of 1832 Egyptian participants, who have conducted an online survey based on the Arabic versions of FCV-19S.ResultsThe Cronbach α value for the Egyptian FCV-19S is 0.87, indicating a good internal reliability. The results of the confirmatory factor analysis show that the unidimensional factor structure of the FCV-19S has fitted well with the data. The FCV-19S is significantly correlated with the seven-item survey. Moreover, the results show a significant negative relationship between Fear of COVID-19 and both wellbeing and life satisfaction (r = -0.42, p < 0.001; r = -0.24, p < 0.01.), respectively.ConclusionThe study supports the one factor model of FCV-19S scale in Egyptian context. The Arabic scale version in the Egyptian context shows excellent reliability and validity. This ensures a good measure that can be accepted for both academia and practitioners for analyzing ill-effects of pandemic impacts and, thereby, reducing them.     

Investigation of COVID-19 fear,treatment compliance,and metabolic control of patients with type 2 diabetes mellitus during the pandemic

AimsThis study was carried out to investigate fear levels, treatment compliance, and metabolic control of type II Diabetes Mellitus patients during the COVID-19 pandemic.MethodsThe study employed a single-center, observational design and was conducted between January and April 2021. The study consisted of 303 patients who attended the internal medicine outpatient clinic of a university hospital in Turkey. For data collection, the Patient Identification Form, COVID-19 Fear Scale, and the Type II Diabetes Treatment Compliance Scale were used. The study complied with the Helsinki Declaration criteria. IBM SPSS v25.0 statistics package program was used for data analysis.ResultsThe mean age of the patients was 45.8 ± 7.5 years, the mean duration of illness was 8.2 ± 3.6 years. Moreover, 40.6% of patients presented with poor levels of treatment compliance. In addition, the mean FCV-19S score of the patients was 29.1 ± 3.05. It was noticeable that those with high mean scores of FCV-19S had poor compliance with treatment and metabolic control during the pandemic (p < 0.05).Practice implicationsFear of COVID-19 negatively affects treatment compliance and metabolic control of type II diabetes patients. The patients avoided attending their regular follow-ups at the hospital due to fear of contracting COVID-19. In order to reduce the fear of COVID-19 it is paramount to maintain optimum metabolic control and treatment compliance.     

Impact of COVID-19 on Cardiovascular Testing in the United States Versus the Rest of the World

ObjectivesThis study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-U.S. institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic.BackgroundThe COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality.MethodsData were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States.ResultsReductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis.ConclusionsWe observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection.     

Initial Findings From the North American COVID-19 Myocardial Infarction Registry

BackgroundThe coronavirus disease 2019 (COVID-19) pandemic has impacted many aspects of ST-segment elevation myocardial infarction (STEMI) care, including timely access to primary percutaneous coronary intervention (PPCI).ObjectivesThe goal of the NACMI (North American COVID-19 and STEMI) registry is to describe demographic characteristics, management strategies, and outcomes of COVID-19 patients with STEMI.MethodsA prospective, ongoing observational registry was created under the guidance of 3 cardiology societies. STEMI patients with confirmed COVID+ (group 1) or suspected (person under investigation [PUI]) (group 2) COVID-19 infection were included. A group of age- and sex-matched STEMI patients (matched to COVID+ patients in a 2:1 ratio) treated in the pre-COVID era (2015 to 2019) serves as the control group for comparison of treatment strategies and outcomes (group 3). The primary outcome was a composite of in-hospital death, stroke, recurrent myocardial infarction, or repeat unplanned revascularization.ResultsAs of December 6, 2020, 1,185 patients were included in the NACMI registry (230 COVID+ patients, 495 PUIs, and 460 control patients). COVID+ patients were more likely to have minority ethnicity (Hispanic 23%, Black 24%) and had a higher prevalence of diabetes mellitus (46%) (all p < 0.001 relative to PUIs). COVID+ patients were more likely to present with cardiogenic shock (18%) but were less likely to receive invasive angiography (78%) (all p < 0.001 relative to control patients). Among COVID+ patients who received angiography, 71% received PPCI and 20% received medical therapy (both p < 0.001 relative to control patients). The primary outcome occurred in 36% of COVID+ patients, 13% of PUIs, and 5% of control patients (p < 0.001 relative to control patients).ConclusionsCOVID+ patients with STEMI represent a high-risk group of patients with unique demographic and clinical characteristics. PPCI is feasible and remains the predominant reperfusion strategy, supporting current recommendations.     

Side effects and antibody titer transition of the BNT162b2 messenger ribonucleic acid coronavirus disease 2019 vaccine in Japan

BackgroundThe coronavirus disease (COVID-19) has afflicted large populations worldwide. Although vaccines aroused great expectations, their side effects on Japanese people and the antibody titer transition after vaccination are unclear.MethodsThe side effects of the BNT162b2 mRNA COVID-19 vaccine in participants who received vaccination at our center were investigated. Some participants were also surveyed for the antibody titer transition.ResultsIn this study, 983 and 798 Japanese participants responded to the first and second doses, respectively. Side effects occurred in 757 (77.0%) and 715 participants (90.0%) after the first and second doses, respectively. No Grade 4 side effects occurred. The second dose had significantly more side effects than the first dose (p < 0.001). Side effects occurred after the second dose in 571 female (92.1%) and 178 male participants (80.1%). Female participants had a higher incidence of side effects than the male participants (p < 0.001). A comparison among the age groups showed significant differences (p = 0.018), and the frequency of side effects decreased with age. Twenty-three individuals participated in the survey of antibody titer transition. After the second vaccine dose, the median antibody titers for IgG and IgM were 3.76 and 0.07 AU/mL, respectively. Both IgG and IgM titers showed a significant increase over the study period (p < 0.001).ConclusionsThe BNT162b2 mRNA COVID-19 vaccine might be safe for Japanese people, and the antibody titer increased with two doses of vaccination. Larger nationwide studies are warranted to verify these findings.     

Fasting Ramadan in patients with T1DM – Saudi Arabia versus other countries during the COVID-19 pandemic

Background and aimsTo compare Saudi Arabia with other countries regarding patient attitudes towards fasting Ramadan and complications related to fasting during the COVID-19 pandemic.MethodsData collected from Saudi Arabia and 12 other mostly Muslim majority countries, via physician administered questionnaire within post Ramadan 2020.Results1485 Type1 diabetes (T1DM) patients analyzed; 705 (47.5%) from Saudi Arabia vs. 780 (52.5%) from other countries. 1056 (71.1%) fasted Ramadan; 636 (90.2%) of Saudi patients vs. 420 (53.8%) of other countries. Experiencing Ramadan during the COVID-19 pandemic did not affect the Saudi T1DM patients’ decision to fast while it significantly influenced their decision in other countries (1.4 vs 9.9%, P < 0.001). More Saudi patients needed to break the fast due to a diabetes related complication compared to other countries (67.4% vs. 46.8%, p=<0.001). The mean number of days fasted in Saudi and other countries was 24 ± 7 and 23 ± 8 days respectively. Hypoglycemic events were more common among Saudi patients during Ramadan compared to other countries 72% and 43.6% (p < 0.001) respectively. There was a significant difference in timing; the largest peak for Saudi Arabia patients was after dawn (35% vs 7%, p < 0.001), while it was pre-sunset for the other countries (23 vs 54%, p = 0.595). Day time-hyperglycemia was also more common among Saudi patients (48.6% vs. 39%, p < 0.001), however it was a less likely cause to break the fast (25.6% vs 38.3%, p < 0.001).ConclusionObserving the fast of Ramadan is extremely common among Saudi T1DM patients compared to other Muslim countries and was not affected by the COVID-19 pandemic. However, it was associated with higher frequency of hypoglycemic and hyperglycemic episodes.     

International Prospective Registry of Acute Coronary Syndromes in Patients With COVID-19

BackgroundPublished data suggest worse outcomes in acute coronary syndrome (ACS) patients and concurrent coronavirus disease 2019 (COVID-19) infection. Mechanisms remain unclear.ObjectivesThe purpose of this study was to report the demographics, angiographic findings, and in-hospital outcomes of COVID-19 ACS patients and compare these with pre–COVID-19 cohorts.MethodsFrom March 1, 2020 to July 31, 2020, data from 55 international centers were entered into a prospective, COVID-ACS Registry. Patients were COVID-19 positive (or had a high index of clinical suspicion) and underwent invasive coronary angiography for suspected ACS. Outcomes were in-hospital major cardiovascular events (all-cause mortality, re–myocardial infarction, heart failure, stroke, unplanned revascularization, or stent thrombosis). Results were compared with national pre–COVID-19 databases (MINAP [Myocardial Ischaemia National Audit Project] 2019 and BCIS [British Cardiovascular Intervention Society] 2018 to 2019).ResultsIn 144 ST-segment elevation myocardial infarction (STEMI) and 121 non–ST-segment elevation acute coronary syndrome (NSTE-ACS) patients, symptom-to-admission times were significantly prolonged (COVID-STEMI vs. BCIS: median 339.0 min vs. 173.0 min; p < 0.001; COVID NSTE-ACS vs. MINAP: 417.0 min vs. 295.0 min; p = 0.012). Mortality in COVID-ACS patients was significantly higher than BCIS/MINAP control subjects in both subgroups (COVID-STEMI: 22.9% vs. 5.7%; p < 0.001; COVID NSTE-ACS: 6.6% vs. 1.2%; p < 0.001), which remained following multivariate propensity analysis adjusting for comorbidities (STEMI subgroup odds ratio: 3.33 [95% confidence interval: 2.04 to 5.42]). Cardiogenic shock occurred in 20.1% of COVID-STEMI patients versus 8.7% of BCIS patients (p < 0.001).ConclusionsIn this multicenter international registry, COVID-19–positive ACS patients presented later and had increased in-hospital mortality compared with a pre–COVID-19 ACS population. Excessive rates of and mortality from cardiogenic shock were major contributors to the worse outcomes in COVID-19 positive STEMI patients.     

Elevated interleukin levels are associated with higher severity and mortality in COVID 19 – A systematic review,meta-analysis,and meta-regression

Background and aimsCOVID 19 pneumonia commonly leads to ARDS. The occurrence of ARDS in COVID 19 patients is thought to occur secondary to an exaggerated immunologic response. In this meta-analysis, we aim to comprehensively study the various levels of immunological parameters in patients with COVID 19.Materials and methodsWe performed a systematic literature search from PubMed, EuropePMC, SCOPUS, Cochrane Central Database, and medRxiv with the search terms, “COVID-19” and “Interleukin”. The outcome of interest was prognosis in COVID 19 patients.ResultsWe performed meta analysis of 16 studies. Higher counts of CD4 and CD8 with Lower Levels of TNF-a, IL2R, IL6, IL8 were observed on patients with good prognosis compared to patients with poor prognosis; −0.57 (pg/mL) (−1.10, −0.04, p = 0.04), (I² 91%, p < 0.001); −579.84 (U/mL) (−930.11, −229.57, p < 0.001), (I² 96%, p < 0.001); −1.49 (pg/mL) (−1.97, −1.01, p < 0.001), (I² 94%, p < 0.001); −0.80 (pg/mL) (−1.21, −0.40, p < 0.001), (I2 79%, p < 0.001); −2.51 (pg/mL) (−3.64, −1.38, p < 0.00001), (I² 98%, p < 0.001) respectively. Meta-regression showed age and hypertension (coefficient: 1.99, and −1.57, p = 0.005, and 0.006) significantly influenced association between IL-6 and poor outcome.ConclusionElevated immune response to coronavirus occurs in COVID 19 patients. Higher counts of CD4 and CD8 were seen in patients with good prognosis compared to patients with poor prognosis, with Lower levels of TNF-a, IL2R, IL6, IL8, were observed in patients with good prognosis compared to patients with poor prognosis.     

Comparison of clinical characteristics and outcomes of COVID-19 patients undergoing early versus late intubation from initial hospital admission: A systematic review and meta-analysis

BackgroundThe true impact of intubation and mechanical ventilation in coronavirus disease 2019 (COVID-19) patients remains controversial.MethodsWe searched Pubmed, Cochrane Library, Embase, and Web of Science databases from inception to October 30th, 2021 for studies containing comparative data of COVID-19 patients undergoing early versus late intubation from initial hospital admission. Early intubation was defined as intubation within 48 h of hospital admission. The primary outcomes assessed were all-cause in-hospital mortality, renal replacement therapy (RRT), and invasive mechanical ventilation (IMV) duration.ResultsFour cohort studies with 498 COVID-19 patients were included between February to August 2020, in which 28.6% had early intubation, and 36.0% underwent late intubation. Although the pooled hospital mortality rate was 32.1%, no significant difference in mortality rate was observed (odds ratio [OR] 0.81; 95% confidence interval 0.32–2.00; P = 0.64) among those undergoing early and late intubation. IMV duration (mean 9.62 vs. 11.77 days; P = 0.25) and RRT requirement (18.3% vs. 14.6%; OR 1.19; P = 0.59) were similar regardless of intubation timing. While age, sex, diabetes, and body mass index were comparable, patients undergoing early intubation had higher sequential organ failure assessment (SOFA) scores (mean 7.00 vs. 5.17; P < 0.001).ConclusionsThe timing of intubation from initial hospital admission did not significantly alter clinical outcomes during the early phase of the COVID-19 pandemic. Higher SOFA scores could explain early intubation. With the advancements in COVID-19 therapies, more research is required to determine optimal intubation time beyond the first wave of the pandemic.     

Cardiac Involvement in Patients Recovered From COVID-2019 Identified Using Magnetic Resonance Imaging

ObjectivesThis study evaluated cardiac involvement in patients recovered from coronavirus disease-2019 (COVID-19) using cardiac magnetic resonance (CMR).BackgroundMyocardial injury caused by COVID-19 was previously reported in hospitalized patients. It is unknown if there is sustained cardiac involvement after patients’ recovery from COVID-19.MethodsTwenty-six patients recovered from COVID-19 who reported cardiac symptoms and underwent CMR examinations were retrospectively included. CMR protocols consisted of conventional sequences (cine, T2-weighted imaging, and late gadolinium enhancement [LGE]) and quantitative mapping sequences (T1, T2, and extracellular volume [ECV] mapping). Edema ratio and LGE were assessed in post–COVID-19 patients. Cardiac function, native T1/T2, and ECV were quantitatively evaluated and compared with controls.ResultsFifteen patients (58%) had abnormal CMR findings on conventional CMR sequences: myocardial edema was found in 14 (54%) patients and LGE was found in 8 (31%) patients. Decreased right ventricle functional parameters including ejection fraction, cardiac index, and stroke volume/body surface area were found in patients with positive conventional CMR findings. Using quantitative mapping, global native T1, T2, and ECV were all found to be significantly elevated in patients with positive conventional CMR findings, compared with patients without positive findings and controls (median [interquartile range]: native T1 1,271 ms [1,243 to 1,298 ms] vs. 1,237 ms [1,216 to 1,262 ms] vs. 1,224 ms [1,217 to 1,245 ms]; mean ± SD: T2 42.7 ± 3.1 ms vs. 38.1 ms ± 2.4 vs. 39.1 ms ± 3.1; median [interquartile range]: 28.2% [24.8% to 36.2%] vs. 24.8% [23.1% to 25.4%] vs. 23.7% [22.2% to 25.2%]; p = 0.002; p < 0.001, and p = 0.002, respectively).ConclusionsCardiac involvement was found in a proportion of patients recovered from COVID-19. CMR manifestation included myocardial edema, fibrosis, and impaired right ventricle function. Attention should be paid to the possible myocardial involvement in patients recovered from COVID-19 with cardiac symptoms.     

Diagnostic prediction of COVID-19 based on clinical and radiological findings in a relatively low COVID-19 prevalence area

BackgroundDistinguishing coronavirus disease 2019 (COVID-19) pneumonia from other lung diseases is often difficult, especially in a highly comorbid patient population in a low prevalence region. We aimed to distinguish clinical data and computed tomography (CT) images between COVID-19 and other lung diseases in an advanced care hospital.MethodsWe assessed clinical characteristics, laboratory data, and chest CT images of patients with COVID-19 and non-COVID-19 patients who were suspected of having COVID-19 between February 20 and May 21, 2020, at the University of Tokyo Hospital.ResultsTypical appearance for COVID-19 on CT images were found in 24 of 29 COVID-19 cases and 21 of 168 non-COVID-19 cases, according to the Radiological Society of North America Expert Consensus Statement (for predicting COVID-19, sensitivity 0.828, specificity 0.875, positive predictive value 0.533, negative predictive value 0.967). When we focused on cases with typical CT images, loss of taste or smell, and close contact with COVID-19 patients were exclusive characteristics for the COVID-19 cases. Among laboratory data, high fibrinogen (P < 0.01) and low white blood cell count (P < 0.01) were good predictors for COVID-19 with typical CT images in multivariate analysis.ConclusionsIn a relatively low prevalence region, CT screening has high sensitivity to COVID-19 in patients with suspected symptoms. When chest CT findings are typical for COVID-19, close contact, loss of taste or smell, lower white blood cell count, and higher fibrinogen are good predictors for COVID-19.     

International Impact of COVID-19 on the Diagnosis of Heart Disease

BackgroundThe coronavirus disease 2019 (COVID-19) pandemic has adversely affected diagnosis and treatment of noncommunicable diseases. Its effects on delivery of diagnostic care for cardiovascular disease, which remains the leading cause of death worldwide, have not been quantified.ObjectivesThe study sought to assess COVID-19’s impact on global cardiovascular diagnostic procedural volumes and safety practices.MethodsThe International Atomic Energy Agency conducted a worldwide survey assessing alterations in cardiovascular procedure volumes and safety practices resulting from COVID-19. Noninvasive and invasive cardiac testing volumes were obtained from participating sites for March and April 2020 and compared with those from March 2019. Availability of personal protective equipment and pandemic-related testing practice changes were ascertained.ResultsSurveys were submitted from 909 inpatient and outpatient centers performing cardiac diagnostic procedures, in 108 countries. Procedure volumes decreased 42% from March 2019 to March 2020, and 64% from March 2019 to April 2020. Transthoracic echocardiography decreased by 59%, transesophageal echocardiography 76%, and stress tests 78%, which varied between stress modalities. Coronary angiography (invasive or computed tomography) decreased 55% (p < 0.001 for each procedure). In multivariable regression, significantly greater reduction in procedures occurred for centers in countries with lower gross domestic product. Location in a low-income and lower–middle-income country was associated with an additional 22% reduction in cardiac procedures and less availability of personal protective equipment and telehealth.ConclusionsCOVID-19 was associated with a significant and abrupt reduction in cardiovascular diagnostic testing across the globe, especially affecting the world’s economically challenged. Further study of cardiovascular outcomes and COVID-19–related changes in care delivery is warranted.     

Prognostic Value of Right Ventricular Longitudinal Strain in Patients With COVID-19

ObjectivesThe aim of this study was to investigate whether right ventricular longitudinal strain (RVLS) was independently predictive of higher mortality in patients with coronavirus disease-2019 (COVID-19).BackgroundRVLS obtained from 2-dimensional speckle-tracking echocardiography has been recently demonstrated to be a more accurate and sensitive tool to estimate right ventricular (RV) function. The prognostic value of RVLS in patients with COVID-19 remains unknown.MethodsOne hundred twenty consecutive patients with COVID-19 who underwent echocardiographic examinations were enrolled in our study. Conventional RV functional parameters, including RV fractional area change, tricuspid annular plane systolic excursion, and tricuspid tissue Doppler annular velocity, were obtained. RVLS was determined using 2-dimensional speckle-tracking echocardiography. RV function was categorized in tertiles of RVLS.ResultsCompared with patients in the highest RVLS tertile, those in the lowest tertile were more likely to have higher heart rate; elevated levels of D-dimer and C-reactive protein; more high-flow oxygen and invasive mechanical ventilation therapy; higher incidence of acute heart injury, acute respiratory distress syndrome, and deep vein thrombosis; and higher mortality. After a median follow-up period of 51 days, 18 patients died. Compared with survivors, nonsurvivors displayed enlarged right heart chambers, diminished RV function, and elevated pulmonary artery systolic pressure. Male sex, acute respiratory distress syndrome, RVLS, RV fractional area change, and tricuspid annular plane systolic excursion were significant univariate predictors of higher risk for mortality (p < 0.05 for all). A Cox model using RVLS (hazard ratio: 1.33; 95% confidence interval [CI]: 1.15 to 1.53; p < 0.001; Akaike information criterion = 129; C-index = 0.89) was found to predict higher mortality more accurately than a model with RV fractional area change (Akaike information criterion = 142, C-index = 0.84) and tricuspid annular plane systolic excursion (Akaike information criterion = 144, C-index = 0.83). The best cutoff value of RVLS for prediction of outcome was −23% (AUC: 0.87; p < 0.001; sensitivity, 94.4%; specificity, 64.7%).ConclusionsRVLS is a powerful predictor of higher mortality in patients with COVID-19. These results support the application of RVLS to identify higher risk patients with COVID-19.     

Hypocalcemia is associated with severe COVID-19: A systematic review and meta-analysis

Background and aimsHypocalcemia is commonly in critically ill patients and studies have shown that hypocalcemia is prevalent in patients with COVID-19. This meta-analysis aimed to evaluate the prognostic performance of hypocalcemia in patients with coronavirus disease 2019 (COVID-19).MethodsWe performed a systematic literature search on PubMed, Scopus, and Embase with keywords “SARS-CoV-2″ OR″COVID-19″ OR ″2019-nCoV” AND “hypocalcemia” up until 10 December 2020. The key exposure was hypocalcemia, defined as serum calcium below study-defined cut-off points. The main outcome was poor outcome, which was a composite of mortality and severity. The effect estimate of the main outcome was reported as odds ratio (OR) and its 95% confidence interval (95% CI). We also generate sensitivity, specificity, positive and negative likelihood ratio (PLR & NLR), diagnostic odds ratio (DOR), and area under curve (AUC).ResultsThere are 2032 patients from 7 studies included in this systematic review and meta-analysis. The incidence of poor outcome in this study was 26%. Serum calcium was lower in patients with poor outcome (mean difference ?0.173 mmol/L [-0.259, ?0.087], p < 0.001; I²: 31.3%). Hypocalcemia was associated with poor outcome (OR 3.19 [2.02, 5.06], p < 0.001; I²: 32.86%); with sensitivity of 0.74 [0.53, 0.88], specificity of 0.54 [0.29, 0.77], PLR of 1.6 [1.1, 2.3], NLR of 0.49 [0.35, 0.66], DOR of 3 [2, 5], and AUC of 0.70 [0.66, 0.74]. In this pooled analysis, the post-test probability was 36% in patients with hypocalcemia and 15% in patients without hypocalcemia.ConclusionHypocalcemia was associated with poor outcome in COVID-19 patients.PROSPERO ID: CRD42020225506.     

Cardiopulmonary Hemodynamic Profile Predicts Mortality After Transcatheter Tricuspid Valve Repair in Chronic Heart Failure

ObjectivesThis study was designed to assess hemodynamic changes in response to transcatheter tricuspid valve edge-to-edge repair (TTVR) and to identify hemodynamic predictors associated with mortality.BackgroundSevere tricuspid regurgitation (TR) is associated with high mortality. TTVR effectively alleviates heart failure symptoms, but comprehensive hemodynamic characterization of patients undergoing TTVR is currently lacking.MethodsThis international, multicenter study included 236 patients undergoing TTVR. Data from clinical assessment, echocardiography, intraprocedural right heart catheterization, and noninvasive cardiac output measurement were analyzed. Hemodynamic predictors for mortality were identified using linear Cox regression analysis and were used for stratification of patients with subsequent analysis of survival time.ResultsPatients (median age 78 years, 53% women) were symptomatic (89% in New York Heart Association functional class III or IV) because of severe TR (grade ≥3+ in 100%). TTVR significantly reduced TR at discharge (grade ≥3+ in 16%; p < 0.001), with a corresponding 19% reduction of the right atrial v wave (21 mm Hg vs. 16 mm Hg; p < 0.001) and an improvement in cardiac output (from 3.5 to 4.0 l/min; p < 0.01). Invasive mean pulmonary artery pressure, transpulmonary gradient, pulmonary vascular resistance, and right ventricular stroke work were significant predictors of 1-year mortality (p < 0.05 for all). Hemodynamic stratification by mean pulmonary artery pressure and transpulmonary gradient best predicted 1-year survival (p < 0.001). Although patients with pre-capillary dominant pulmonary hypertension showed an unfavorable prognosis (1-year survival 38%), patients without or with post-capillary pulmonary hypertension had favorable outcome (1-year survival 92% or 78%, respectively).ConclusionsInvasive assessment of cardiopulmonary hemodynamic status predicts survival after TTVR. Invasive hemodynamic characterization may help identify patients profiting most from TTVR.     

Glycemic control metrics using flash glucose monitoring and hospital complications in patients with COVID-19

Background and aimsFew studies have reported on the use of continuous glucose monitoring (CGM) during the Covid-19 pandemic. We aimed to examine glycemic control metrics using flash glucose monitoring during insulin treatment and the clinical outcome in hospitalized patients with COVID-19.MethodsProspective, single-center cohort of adult patients diagnosed with type 2 diabetes or hyperglycemia and COVID-19 infection treated with basal bolus insulin regimen. Glycemic control was assessed with the use of intermittent Freestyle Libre flash glucose monitoring during the hospital stay. Outcome of interest were time in range [TIR], time above [TAR] and below [TBR] range, glycemic variability [coefficient of variation [% CV]), and differences in a composite of complications including ICU admission, acute respiratory distress syndrome (ARDS) and acute kidney injury.ResultsA total of 60 patients were included (44 known diabetes and 16 new onset hyperglycemia). In total 190,080 data points of CGM were available, of which 72.5% of values were within the target area [TIR (70–180 mg/dL)], 22% TAR (>180 mg/dL), and 3% were TBR (<70 mg/dL). During treatment, the coefficient of variation (% CV) was 30%. There were no association with TIR, but patients with TAR >180 mg/dl had higher rates of a composite of complications (22.5% vs 16%, p = 0.04).ConclusionsBasal bolus insulin regimen was safe and effective in achieving inpatient glycemic control in most patients with COVID-19.

Serum gasdermin D levels are associated with the chest computed tomography findings and severity of COVID-19

BackgroundThe role of programmed cell death, especially pyroptosis and apoptosis, in unfavorable immune responses in COVID-19 remains to be elucidated.MethodsWe conducted a cross-sectional analysis to investigate the association between the serum gasdermin D (GSDMD) levels, a pyroptotic marker, and caspase-cleaved cytokeratin 18 fragment (M30), an apoptotic marker, and the clinical status and abnormal chest computed tomography (CT) findings in patients with COVID-19.ResultsIn this study, 46 patients diagnosed with COVID-19 were divided into the following three groups according to the disease severity: mild to moderate group (n = 10), severe group (n = 14), and critical group (n = 22). The serum GSDMD levels were higher in the critical group than in the mild to moderate group (P = 0.016). In contrast, serum M30 levels were lower in the critical group than in the severe group (P = 0.048). Patients who required mechanical ventilation or died had higher serum GSDMD levels than those who did not (P = 0.007). Area of consolidation only and of ground glass opacity plus consolidation positively correlated with serum GSDMD levels (r = 0.56, P < 0.001 and r = 0.53, P < 0.001, respectively).ConclusionHigher serum GSDMD levels are associated with critical respiratory status and the consolidation area on chest CT in patients with COVID-19, suggesting that excessive activation of pyroptosis may affect the clinical manifestations in patients with COVID-19.     

Combination of F-ASO and Targeted Medical Therapy in Patients With Secundum ASD and Severe PAH

ObjectivesThis study was conducted to investigate the combined use of fenestrated atrial septal occluder (F-ASO) and targeted medical therapy (TMT) in patients with secundum atrial septal defect (ASD) and severe pulmonary arterial hypertension (PAH).BackgroundTreatment of patients with ASD and severe PAH is still challenging.MethodsAfter ethical approval was obtained, 56 consecutive patients with ASD with severe PAH were included (7 men, 49 women; median age 50.5 years; mean ASD size 26.9 ± 4.6 mm). After 3 months of TMT, transcatheter closure was performed using F-ASO in patients with ratios of pulmonary to systemic blood flow ≥1.5. TMT was continued post-operatively together with 6 months of dual-antiplatelet therapy. The hemodynamic variables during baseline, TMT alone, and combined treatment with F-ASO were compared.ResultsAfter only TMT, systolic pulmonary arterial pressure (−14.5 mm Hg; p < 0.001), pulmonary vascular resistance (−3.9 Wood units; p < 0.001), and exercise capacity (+72.0 m; p < 0.001) improved. Ratio of pulmonary to systemic blood flow increased by 0.9 (p < 0.001), with adverse cardiac remodeling (right ventricular dimension +3.5 mm; p < 0.001). Closure with F-ASO (median size 34.0 mm) led to further decrease in systolic pulmonary artery pressure (−6.0 mm Hg; p < 0.001). Follow-up (median duration 10 months) revealed further improvement in exercise capacity (+60.5 m; p < 0.001), with favorable cardiac remodeling (right ventricular dimension −9.9 mm; p < 0.001). In addition, all fenestrations were stable (p = 0.699), with negligible shunt (median ratio of pulmonary to systemic blood flow 1.1) and no complications. One year later, pulmonary artery pressure was normalized in 8 of 19 patients, and PAH recurred in 5 patients after discontinuation of TMT.ConclusionsIn patients with ASD and severe PAH, combination of F-ASO and TMT was a safe and effective procedure. Compared with TMT alone, the combined treatment further improved exercise capacity, with favorable cardiac remodeling.     

Differential white blood cell count in the COVID-19: A cross-sectional study of 148 patients

BackgroundSARS-CoV-2 infection alters various blood parameters, which may indicate disease severity and thus help in better clinical management.AimTo study the association between various hematological parameters and disease severity of COVID-19. To analyze the effects of hypertension and diabetes on neutrophil-lymphocyte ratio and neutrophil-monocyte ratio in patients suffering from COVID-19.Materials and methodsThe study was a cross-sectional study involving 148 laboratory-confirmed cases of SARS-CoV-2 infection. The patients were divided into three groups on the basis of disease severity. Various hematological parameters were analyzed. The effects of hypertension and diabetes on NLR and NMR in COVID-19 patients were evaluated.ResultsOf the 148 patients, 78.4%, 8.1% and 13.5% cases were in the mild, moderate and severe groups, respectively. Mean age was 42.63 ± 16.04 years (IQR: 29, 54.75; Range: 7–74). 58.8% patients were male while the rest (42.2%) were female. Mean TLC (cells/mm³), neutrophil (%), lymphocyte (%), monocyte (%), eosinophil (%), neutrophil-lymphocyte ratio (NLR) and neutrophil-monocyte ratio (NMR) among mild, moderate and severe COVID-19 was statistically significant (p < 0.05). Basophil (%) and lymphocyte-monocyte ratio (LMR) was statistically insignificant among the three groups. Lymphocyte (%), monocyte (%) and eosinophil (%) were negatively correlated to disease severity. Among diabetics, both NLR and NMR were statistically significant (p < 0.05). However, among hypertensive cases, only the NLR was statistically significant.ConclusionOlder age, higher TLC, neutrophilia, lymphopenia, eosinopenia, high NLR and high NMR are associated with severe COVID-19. High NLR and high NMR are indicative of severe disease among diabetic patients. High NLR also indicates severe disease among hypertensive patients.     

Pattern of liver function and clinical profile in COVID-19: A cross-sectional study of 91 patients

Background– COVID-19 caused by SARS-CoV-2 leads to myriad range of organ involvement including liver dysfunction.AimTo analyse the liver function in patients with COVID-19 and their association with respect to age, sex, severity of disease and clinical features.Materials and methodsThis study was a cross-sectional study done at Rajendra Institute of Medical Sciences, Ranchi. 91 patients admitted with confirmed SARS-CoV-2 infection were included in this study and divided into asymptomatic, mild, moderate and severe groups. Liver function tests were compared among different severity groups.ResultsOf 91 patients with COVID-19, 70 (76.9%) had abnormal liver function. Aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), total bilirubin levels was 1–2 × ULN in 33(36.3%), 34(37.3%), 12(13.2%), 6(6.6%) cases and >2 × ULN in 20(22%), 18(19.8%), 7(7.7%) and 2 (2.2%) cases respectively. Mean AST and ALP levels among different severity groups of COVID-19 was statistically significant (p < 0.05) whereas mean ALT and total bilirubin levels was statistically non-significant (p > 0.05). There was no statistical difference between males and females with regard to abnormal liver function. Liver injury was seen in 64.3% cases of hypertension and 73.3% cases of diabetes. Fever, myalgia, headache and breathlessness were found to be correlated significantly with severity of disease.ConclusionLiver injury is common in SARS-CoV-2 infection and is more prevalent in the severe disease group. Aspartate transaminase and alkaline phosphatase are better indicators of covid-19 induced liver injury than alanine transaminase and total bilirubin.
