    There is ongoing debate as to whether angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin-receptor blockers (ARBs) use is associated with poor prognosis of coronavirus disease MESHD-2019 (COVID-19). We sought to investigate the association between ACEI/ARB use and risk of poor clinical outcomes from COVID-19. We identified 1,290 patients with hypertension MESHD hypertension HP, of which 682 had recorded ACEI/ARB use and 608 without the use during 30 days preceding the date of COVID-19 diagnosis in completely enumerated COVID-19 cohort in South Korea. Our primary endpoint was the clinical outcomes comprised of all-cause mortality, use of mechanical ventilation, intensive care unit (ICU) admission, and sepsis MESHD sepsis HP. We used inverse probability of treatment weighting (IPTW) to mitigate selection bias, and Poisson regression model to estimate the relative risks (RR) and 95% confidence intervals (CI) to compare outcomes in ACEI/ARB users with non-users. Compared to non-use, ACEI/ARB use was associated with lower clinical outcomes (IPTW adjusted RR, 0.60; 95% CI, 0.42-0.85; p=0.0046). When assessed by individual outcomes, ACEI/ARB use was not associated with all-cause mortality (IPTW adjusted RR, 0.62; 95% CI, 0.35-1.09; p=0.0973) and respiratory events (IPTW adjusted RR, 0.99; 95% CI, 0.84-1.17; p=0.9043). Subgroup analysis showed a trend toward protective role of ACEIs and ARBs against overall outcomes in men (IPTW adjusted RR, 0.84; 95% CI, 0.69-1.03; p-for-interaction=0.008) and with pre-existing respiratory disease MESHD (IPTW adjusted RR, 0.74; 95% CI, 0.60-0.92; p-for-interaction=0.0023). We present clinical evidence to support continuing ACE/ARB use in completely enumerated hypertensive COVID-19 cohort in South Korea.

    Objective: To identify sex-specific effects of risk factors for in-hospital mortality among COVID-19 patients admitted to a hospital system in New York City. Design: Prospective observational cohort study with in-hospital mortality as the primary outcome. Setting: Five acute care hospitals within a single academic medical system in New York City. Participants: 3,086 hospital inpatients with COVID-19 admitted on or before April 13, 2020 and followed through June 2, 2020. Follow-up till discharge or death MESHD was complete for 99.3% of the cohort. Results: The majority of the cohort was male TRANS (59.6%). Men were younger (median 64 vs. 70, p<0.001) and less likely to have comorbidities such as hypertension MESHD hypertension HP (32.5% vs. 39.9%, p<0.001), diabetes (22.6% vs. 26%, p=0.03), and obesity MESHD obesity HP (6.9% vs. 9.8%, p=0.004) compared to women. Women had lower median values of laboratory markers associated with inflammation MESHD compared to men: white blood SERO cells (5.95 vs. 6.8 K/uL, p<0.001), procalcitonin (0.14 vs 0.21 ng/mL, p<0.001), lactate dehydrogenase (375 vs. 428 U/L, p<0.001), C-reactive protein (87.7 vs. 123.2 mg/L, p<0.001). Unadjusted mortality was similar between men and women (28.8% vs. 28.5%, p=0.84), but more men required intensive care than women (25.2% vs. 19%, p<0.001). Male TRANS sex was an independent risk factor for mortality (OR 1.26, 95% 1.04-1.51) after adjustment for demographics, comorbidities, and baseline hypoxia MESHD. There were significant interactions between sex and coronary artery disease MESHD (p=0.038), obesity MESHD obesity HP (p=0.01), baseline hypoxia MESHD (p<0.001), ferritin (p=0.002), lactate dehydrogenase (p=0.003), and procalcitonin (p=0.03). Except for procalcitonin, which had the opposite association, each of these factors was associated with disproportionately higher mortality among women. Conclusions: Male TRANS sex was an independent predictor of mortality, consistent with prior studies. Notably, there were significant sex-specific interactions which indicated a disproportionate increase in mortality among women with coronary artery disease MESHD, obesity MESHD obesity HP, and hypoxia MESHD. These new findings highlight patient subgroups for further study and help explain the recognized sex differences in COVID-19 outcomes.

    Background Comprehensive evidence synthesis on the associations between comorbidities and behavioural factors with hospitalisation, Intensive Care Unit (ICU) admission, and death MESHD due to COVID-19 is lacking leading to inconsistent national and international recommendations on who should be targeted for non-pharmaceutical interventions and vaccination strategies. Methods We performed a systematic review and meta-analysis on studies and publicly available data to quantify the association between predisposing health conditions, demographics, and behavioural factors with hospitalisation, ICU admission, and death MESHD from COVID-19. We provided ranges of reported and calculated effect estimates and pooled relative risks derived from a meta-analysis and meta-regression. Results 75 studies were included into qualitative and 74 into quantitative synthesis, with study populations ranging from 19 - 44,672 COVID-19 cases. The risk of dying from COVID-19 was significantly associated with cerebrovascular [pooled RR 2.7 (95% CI 1.7-4.1)] and cardiovascular [RR 3.2 (CI 2.3-4.5)] diseases MESHD, hypertension MESHD hypertension HP [RR 2.6 (CI 2.0-3.4)], and renal disease MESHD [RR 2.5 (CI 1.8-3.4)]. Health care workers had lower risk for death MESHD and severe outcomes of disease MESHD (RR 0.1 (CI 0.1-0.3). Our meta-regression showed a decrease of the effect of some comorbidities on severity of disease MESHD with higher median age TRANS of study populations. Associations between comorbidities and hospitalisation and ICU admission were less strong than for death MESHD. Conclusions We obtained robust estimates on the magnitude of risk for COVID-19 hospitalisation, ICU admission, and death MESHD associated with comorbidities, demographic, and behavioural risk factors. We identified and confirmed population groups that are vulnerable and that require targeted prevention approaches.

    Bangladesh is in the rising phase of the ongoing pandemic of the coronavirus disease MESHD 2019 (COVID-19), caused by severe acute respiratory syndrome MESHD coronavirus-2 (SARS-CoV-2). The scientific literature on clinical manifestations of COVID-19 patients from Bangladesh is scarce. This study aimed to report the sociodemographic and clinical characteristics of patients with COVID-19 in Bangladesh. We conducted a cross-sectional study at three dedicated COVID-19 hospitals. The severity of the COVID-19 cases was assessed based on the WHO interim guidance. Data were collected only from non-critical COVID-19 patients as critical patients required immediate intensive care admission making them unable to respond to the questions. A total of 103 RT-PCR confirmed non-critical COVID-19 patients were enrolled. Most of the patients (71.8%) were male TRANS. Mild, moderate and severe illness were assessed in 74.76%, 9.71% and 15.53% of patients respectively. Nearly 52.4% of patients had a co-morbidity, with hypertension MESHD hypertension HP being the most common (34%), followed by diabetes mellitus MESHD diabetes mellitus HP (21.4%) and ischemic heart disease MESHD (9.7%). Fever MESHD Fever HP (78.6%), weakness (68%) and cough MESHD cough HP (44.7%) were the most common clinical manifestations. Other common symptoms included loss of appetite (37.9%), difficulty in breathing (37.9%), altered sensation of taste or smell (35.0%), headache MESHD headache HP (32%) and body ache (32%). The median time from onset of symptom TRANS to attending hospitals was 7 days (IQR 4-10). This study will help both the clinicians and epidemiologists to understand the magnitude and clinical spectrum of COVID-19 patients in Bangladesh.

    Background: Need for catecholamines is frequent in COVID-19 patients, but the main echocardiographic patterns are unknown. The objective was to report the main echo patterns in critically-ill COVID-19 patients. Methods: Observational and descriptive study in consecutive COVID-19 patients admitted to the ICU between March 12 and May 8, 2020. Systematic critical care echocardiography (CCE) was performed and retrospectively analyzed off-line. Echo values are reported in the overall population and in patients who required catecholamine infusion during the first 2 days following admission (D1-2) or afterwards until day 7 (D3-7). Results: Of the 79 patients (78% male TRANS; median age TRANS 63 [56-71]; body mass index 29 [26-30]) included, 90% had at least 1 comorbidity. PaO2/FiO2 at admission was 85 [67-162] mmHg. 53% of patients were mechanically ventilated. ICU length of stay was 9 [5-16] days and mortality 34%. 134 echocardiographic studies were performed during the first week in 65 patients. Pulmonary artery acceleration time was decreased (77 [65-97] ms), suggesting pulmonary hypertension MESHD hypertension HP. All 39 patients (49%) who required catecholamine infusion underwent CCE and 25.6% had left ventricular (LV) systolic dysfunction, 28.2% acute cor pulmonale HP (ACP), 7.7% hypovolemia MESHD hypovolemia HP, and 38.5% vasoplegia MESHD. Modification of echo patterns was observed at D3-7, with less LV systolic dysfunction and more ACP, which was the most frequent pattern. Computed tomography pulmonary angiography in 6 patients with ACP indicated intrapulmonary thrombus in 4. Conclusion: Different echocardiographic patterns were observed during the first week following ICU admission in COVID-19 patients. ACP was frequent and often related to thrombus in the pulmonary circulation.

    BACKGROUND: Coronavirus disease MESHD-2019 (COVID-19) is a growing pandemic with an increasing death MESHD toll that has been linked to various comorbidities as well as racial disparity. However, the specific characteristics of these at-risk populations are still not known and approaches to lower mortality are lacking. METHODS: We conducted a retrospective electronic health record data analysis of 25,326 subjects tested for COVID-19 between 2/25/20 and 6/22/20 at the University of Alabama at Birmingham Hospital, a tertiary health care center in the racially diverse Southern U.S. The primary outcome was mortality in COVID-19-positive subjects and the association with subject characteristics and comorbidities was analyzed using simple and multiple linear logistic regression. RESULTS: The odds ratio of contracting COVID-19 was disproportionately high in Blacks/African-Americans (OR 2.6; 95%CI 2.19-3.10; p<0.0001) and in subjects with obesity MESHD obesity HP (OR 1.93; 95%CI 1.64-2.28; p<0.0001), hypertension MESHD hypertension HP (OR 2.46; 95%CI 2.07-2.93; p<0.0001), and diabetes (OR 2.11; 95%CI 1.78-2.48; p<0.0001). Diabetes was also associated with a dramatic increase in mortality (OR 3.62; 95%CI 2.11-6.2; p<0.0001) and emerged as an independent risk factor in this diverse population even after correcting for age TRANS, race, sex, obesity MESHD obesity HP and hypertension MESHD hypertension HP. Interestingly, we found that metformin treatment was independently associated with a significant reduction in mortality in subjects with diabetes and COVID-19 (OR 0.33; 95%CI 0.13-0.84; p=0.0210). CONCLUSION: Thus, these results suggest that while diabetes is an independent risk factor for COVID-19-related mortality, this risk is dramatically reduced in subjects taking metformin, raising the possibility that metformin may provide a protective approach in this high risk population.

    Background: To compare the clinical outcomes between patients with and without diabetes admitted to hospital with COVID-19.Methods: Retrospective multicentre cohort study from 24 academic tertiary medical centres in France including 2851 patients (675 with diabetes) hospitalised for COVID-19 between February 26 and April 20, 2020. A propensity score matching method (1:1 matching including patient characteristics, medical history, vital signs, and laboratory results) was used to compare patients with and without diabetes (n=603 in each group). The primary outcome was admission to intensive care unit (ICU) or in-hospital death MESHD. Results: Patients with diabetes were older (71 ± 13 vs. 65 ± 18 years; p<0.001), were less often female TRANS (38% vs. 44%; p<0.001) and more likely to have comorbidities: hypertension MESHD hypertension HP (79% vs 42%; p<0.001), coronary heart disease MESHD (23% vs 9%; p<0.001), stroke MESHD stroke HP (13% vs 8%; p<0.001), heart failure MESHD (17% vs 9%; p<0.001), chronic kidney disease HP kidney disease MESHD (26% vs 10%; p<0.001), and chronic obstructive pulmonary disease MESHD chronic obstructive pulmonary disease HP (7% vs 5%; p<0.05). The primary outcome occurred in 584 (36.4%) patients with diabetes compared to 246 (26.8%) in those without diabetes (p<0.001). After propensity score matching, the risk of primary outcome was similar in patients with and without diabetes (hazard ratio [HR] 1.16, 95%CI 0.95-1.41, p=0.14) and was 1.29 (95%CI 0.97 – 1.69) for in-hospital mortality, 1.26 (95%CI 0.93 – 1.72) for mortality without transfer in ICU, and 1.14 (95%CI 0.88 – 1.47) for transfer to ICU.Conclusions: In this retrospective cohort of patients hospitalised for COVID-19, diabetes was not significantly associated with a higher risk of COVID-19 severe outcomes after propensity score matching.Trial registration NCT04344327

    Background: Identification of risk factors for COVID-19-associated hospitalization is needed to guide prevention and clinical care. Objective: To examine if age TRANS, sex, race/ethnicity, and underlying medical conditions is independently associated with COVID-19-associated hospitalizations. Design: Cross-sectional. Setting: 70 counties within 12 states participating in the Coronavirus Disease MESHD 2019-Associated Hospitalization Surveillance Network (COVID-NET) and a population-based sample of non-hospitalized adults TRANS residing in the COVID-NET catchment area from the Behavioral Risk Factor Surveillance System. Participants: U.S. community-dwelling adults TRANS ([≥]18 years) with laboratory-confirmed COVID-19-associated hospitalizations, March 1- June 23, 2020. Measurements: Adjusted rate ratios (aRR) of hospitalization by age TRANS, sex, race/ethnicity and underlying medical conditions ( hypertension MESHD hypertension HP, coronary artery disease MESHD, history of stroke MESHD stroke HP, diabetes, obesity MESHD obesity HP [BMI [≥]30 kg/m2], severe obesity MESHD obesity HP [BMI[≥]40 kg/m2], chronic kidney disease HP kidney disease MESHD, asthma MESHD asthma HP, and chronic obstructive pulmonary disease MESHD chronic obstructive pulmonary disease HP). Results: Our sample included 5,416 adults TRANS with COVID-19-associated hospitalizations. Adults TRANS with (versus without) severe obesity MESHD obesity HP (aRR:4.4; 95%CI: 3.4, 5.7), chronic kidney disease HP kidney disease MESHD (aRR:4.0; 95%CI: 3.0, 5.2), diabetes (aRR:3.2; 95%CI: 2.5, 4.1), obesity MESHD obesity HP (aRR:2.9; 95%CI: 2.3, 3.5), hypertension MESHD hypertension HP (aRR:2.8; 95%CI: 2.3, 3.4), and asthma MESHD asthma HP (aRR:1.4; 95%CI: 1.1, 1.7) had higher rates of hospitalization, after adjusting for age TRANS, sex, and race/ethnicity. In models adjusting for the presence of an individual underlying medical condition, higher hospitalization rates were observed for adults TRANS [≥]65 years, 45-64 years (versus 18-44 years), males TRANS (versus females TRANS), and non-Hispanic black and other race/ethnicities (versus non-Hispanic whites). Limitations: Interim analysis limited to hospitalizations with underlying medical condition data. Conclusion: Our findings elucidate groups with higher hospitalization risk that may benefit from targeted preventive and therapeutic interventions.

    Background: The 2019 coronavirus disease MESHD (COVID-19) has become an unprecedented public health crisis with nearly 16 million confirmed cases TRANS and 630,000 deaths MESHD worldwide. Methods: We retrospectively investigated the demographic, clinical, laboratory, radiological and treatment data of COVID-19 patients consecutively enrolled from January 18 to May 15, 2020, in Taihe and Jinzhou central hospital. Results: Of all 197 patients, the median age TRANS was 66.5 years (IQR 7-76), and 120 (60.9%) patients were males TRANS. We identified 88 (44.7%) of 197 COVID-19 patients as the disease progression MESHD (aggravation) cases. The aggravation cases tend to have more medical comorbidity: hypertension MESHD hypertension HP (34.1%), diabetes (30.7%), and presented with dyspnea MESHD dyspnea HP (34.1%), neutrophilia HP (60.2%), and lymphocytopenia (73.9%), compared with those without. And the patients with disease progression MESHD showed significantly higher level of Fibrinogen (Fbg), D-dimer, IL-6, C-reactive protein (CRP), procalcitonin (PCT), and serum SERO ferritin, and were more prone to develop organ damage in the liver, kidney, and heart (P<0.05). Multivariable regression showed that advanced age TRANS, comorbidities, lymphopenia MESHD lymphopenia HP, and elevated level of Fbg, lactate dehydrogenase (LDH), Cardiac troponin (CTnI), IL-6, serum SERO ferritin were the significant predictors of disease progression MESHD. Further, we investigated antibody SERO responses to SARS-CoV-2 and found that the levels of IgM and IgG were significantly higher in the disease progression MESHD cases compared to non-progression cases from 3 weeks after symptom onset TRANS. In addition, the disease progression MESHD group tended to peak later and has a more vigorous IgM/IgG response against SARS-CoV-2. Further, we performed Kaplan-Meier analysis and found that 61.6% of patients had not experienced ICU transfer or survival from hospital within 25 days from admission.Conclusions: Investigating the potential factors of advanced age TRANS, comorbidities and elevated level of IL-6, serum SERO ferritin and Kaplan-Meier analysis enables early identification and management of patients with poor prognosis. Detection of the dynamic antibody SERO may offer vital clinical information during the course of SARS-CoV-2 and provide prognostic value for patients infection MESHD.

    BACKGROUND: Despite the significant morbidity and mortality caused by the 2019 novel coronavirus disease MESHD (COVID-19), our understanding of basic disease MESHD epidemiology remains limited. This study aimed to describe key patient characteristics, comorbidities, treatments, and outcomes of a large U.S.-based cohort of patients hospitalized with COVD-19 using electronic health records (EHR). METHODS: We identified patients in the Optum De-identified COVID-19 EHR database who had laboratory-confirmed COVID-19 or a presumptive diagnosis between 20 February 2020 and 6 June 2020. We included hospitalizations that occurred 7 days prior to, or within 21 days after, COVID-19 diagnosis. Among hospitalized patients we describe the following: vital statistics and laboratory results on admission, relevant comorbidities (using diagnostic, procedural, and revenue codes), medications (NDC, HCPC codes), ventilation, intensive care unit (ICU) stay, length of stay (LOS), and mortality. RESULTS: We identified 76,819 patients diagnosed with COVID-19, 16,780 of whom met inclusion criteria for COVID-related hospitalization. Over half the cohort was over age TRANS 50 (74.5%), overweight MESHD overweight HP or obese (77.2%), or had hypertension MESHD hypertension HP (58.1%). At admission, 30.3% of patients presented with fever MESHD fever HP (>38C) and 32.3% had low oxygen saturation (<90%). Among the 16,099 patients with complete hospital records, we observed that 58.9% had hypoxia MESHD, 23.4% had an ICU stay during hospitalization, 18.1% were ventilated, and 16.2% died. The median LOS was 6 days (IQR: 4, 11). CONCLUSIONS: To our knowledge, this is the largest descriptive study of patients hospitalized with COVID-19 in the United States. We report summary statistics of key clinical outcomes that provide insights to better understand COVID-19 disease MESHD epidemiology.
