    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: Acute respiratory distress HP syndrome MESHD (ARDS) was the most common complication of coronavirus disease MESHD-2019(COVID-19), leading to poor clinical outcomes. However, the model to predict the in-hospital incidence of ARDS in patients with COVID-19 is limited. Therefore, we aimed to develop a predictive nomogram for the in-hospital incidence of ARDS in COVID-19 patients.Methods: Patients with COVID-19 admitted to Changsha Public Health Centre between Jan 30, 2020, and Feb 22, 2020, were enrolled. Clinical characteristics and laboratory variables were analyzed in patients with ARDS. Risk factors for ARDS were selected by LASSO binary logistic regression. Nomogram was established based on risk factors and validated by the dataset.Results: A total of 113 patients, involving 99 in the non-ARDS group and 14 in the ARDS group were included in the study. 8 variables including hypertension MESHD hypertension HP, chronic obstructive pulmonary disease MESHD chronic obstructive pulmonary disease HP (COPD), cough MESHD cough HP, lactate dehydrogenase (LDH), creatine kinase (CK), white blood SERO count (WBC), body temperature, and heart rate were identified to be included in the model. The specificity, sensitivity SERO, and accuracy of the full model were 100%, 85.7%, and 87.5% respectively. The calibration curve also showed good agreement between the predicted and observed values in the model.Conclusions: The nomogram can predict the in-hospital incidence of ARDS in COVID-19 patients. It helps physicians to make an individualized treatment plan for each patient.

    BackgroundSARS-CoV-2 virus infection MESHD leads to a severe and dysbalanced inflammatory response with hypercytokinemia and immunodepression. Systemic inflammation MESHD due to viral infections MESHD can potentially cause vascular damage including disruption of blood SERO-brain barrier (BBB) and alterations in coagulation system that may also lead to cardiovascular and neurovascular events. Here, we report the first case of COVID-19 infection MESHD leading to aneurysmal subarachnoid haemorrhage (aSAH). Case DescriptionA 61-year-old woman presented with dyspnea MESHD dyspnea HP, cough MESHD cough HP and fever MESHD fever HP. She was over weight with Body MESHD mass-index of 34 and history of hypertension MESHD hypertension HP. No history of subarachnoid hemorrhage MESHD subarachnoid hemorrhage HP in the family. She was admitted in ICU due to low oxygen saturation (89%). A chest CT showed typical picture of COVID-19 pneumonia MESHD pneumonia HP. Oropharyngeal swab with a PCR-based testing was COVID-19 positive. She was prescribed with favipiravir and hydroxychloroquine in Addition to oxygen support. On second day she experienced sudden headache MESHD headache HP and losst conciousness. A computer tomography (CT) with CT-angiography revealed subarachnoid haemorrhage in basal cisterns from a ruptured MESHD anterior communicating artery aneurysm MESHD. The aneurysm MESHD was clipped microsurgically through a standard pterional approach and the patient was admitted again to intensive care unit for further intensive medical treatment. Post-operative the patient showed slight motor dysphasia HP. No other neurological deficits.ConclusionAneurysmal subarachnoid haemorrhage secondary to COVID-19 infection MESHD might be triggered by systemic inflammation MESHD. COVID-19 infection MESHD could be one of the risk factors leading to instability and rupture MESHD of intracranial aneurysm MESHD.

    Background: Coronavirus disease MESHD 2019 also known as COVID-19 has been recognized by WHO as a global pandemic and has spread to most of the world. The disease MESHD has a multitude of clinical presentations, and especially the development of acute kidney injury MESHD acute kidney injury HP has been associated with increased mortality.Case Presentation: A 71-year old Caucasian male TRANS was admitted with fever MESHD fever HP and dyspnea MESHD dyspnea HP to the emergency MESHD department. His medical history included type 2 diabetes and hypertension MESHD hypertension HP. Blood SERO tests showed a normal kidney function before admission with a creatinine of 0,8 mg/dL. Clinical examination, blood SERO tests and Chest X-ray suggested COVID-19. At admission the diagnose COVID-19 was confirmed, fluid therapy was commenced and Angiotensin-converting enzyme therapy discontinued. The patients was intubated due to respiratory failures HP and transferred to the intensive care ward where he developed acute anuric kidney failure and was started in continuous renal replacement therapy. After 6 days of dialysis treatment his kidney function slowly started to improve, and he was discharged after 26 days of admission. 42 days after admission his creatinine was measured to 1.3 mg/dLConclusion: We present the rare case of a Caucasian male TRANS, who not only survived COVID-19 induced kidney failure that required continuous renal replacement therapy, but returned to almost baseline creatinine. We discuss the role of Angiotensin-converting enzyme inhibitor treatment in COVID-19 and the potential pathophysiological mechanism surrounding AKI in COVID-19 patients in literature, and connect it to our case report.

    Background: Dyslipidemia plays an important role in the pathogenesis and evolution of critical illness MESHD, but limited information exists regarding the lipid metabolism of severe coronavirus disease MESHD 2019 (COVID-19) patients. The aim of this study was to investigate role of dyslipidemia in patients with severe COVID-19Methods: We retrospectively reviewed 216 severe COVID-19 patients with clarified outcomes (discharged or deceased), admitted to the West Court of Union Hospital in Wuhan, China, between February 1 and March 31, 2020. The dynamic changes of lipid profiles and their relationships with disease MESHD severity and clinical outcomes were analyzed.Results: A total of 216 severe COVID-19 patients, including 24 non-survivors and 192 survivors, were included in the final analyses. The levels of high-density lipoprotein cholesterol (HDL-C) and apolipoprotein AI (Apo-AI) on admission were significantly lower in non-survivors compared to survivors. During hospitalization, low-density lipoprotein cholesterol (LDL-C), total cholesterol(TC), HDL-C and Apo-AI were shown an increasing trend in survivors, but maintained lower levels or shown downward trend in non-survivors. The serum SERO levels of HDL-C and Apo-AI were inversely correlated with C-reactive protein (CRP), length of hospital stay of survivors and disease MESHD severity. The receiver operating characteristic (ROC) curve analysis identified a CRP/ HDL-C ratio cut-off value of 62.54 as the predictor for in-hospital mortality (AUC=0.823, Sensitivity=83.3%, Specificity=70.8%). Logistic regression analysis demonstrated that hypertension MESHD hypertension HP, neutrophils-to-lymphocytes ratio(NLR), platelet count and high CRP/ HDL-C ratio (>62.54) were independent factors to predict in-hospital mortality.Conclusions: The results demonstrated that dyslipidemia was associated with the inflammatory response, disease MESHD severity and poor prognosis of COVID-19. High CRP/ HDL-C ratio may serve as an independently potential predictor for hospital mortality among patients with severe COVID-19.

    The COVID-19 pandemic has affected more than 10 million people worldwide with mortality exceeding3 half a million patients. Risk factors associated with severe disease MESHD and mortality include advanced age TRANS,4 hypertension MESHD hypertension HP, diabetes, and obesity MESHD obesity HP.1 Clear mechanistic understanding of how these comorbidities5 converge to enable severe infection HP infection MESHD is lacking. Notably each of these risk factors pathologically disrupts6 the lipidome and this disruption may be a unifying feature of severe COVID-19.1-7 Here we provide the first in depth interrogation of lipidomic changes, including structural-lipids as well as the eicosanoids and docosanoids lipid mediators (LMs), that mark COVID-19 disease MESHD severity. Our data reveal that progression from moderate to severe disease MESHD is marked by a loss of specific immune regulatory LMs and increased pro-inflammatory species. Given the important immune regulatory role of LMs, these data provide mechanistic insight into the immune balance in COVID-19 and potential targets for therapy with currently approved pharmaceuticals.8

    Background In-hospital death MESHD risks vary in COVID-19 patients with comorbidities. Kidney function decline is prevalent in this course. Methods To explore the exact role of deteriorated kidney function, we applied a retrospective cohort study including 1266 participants in Wuhan Tongren Hospital between January 27 and March 3, 2020. Demographic characteristics, preexisting comorbidities history, organ function data and outcomes were extracted. Deteriorated kidney function was identified as the decline percentage, assessed by an increase in peak serum SERO creatinine from the baseline. Mediating effect was calculated by mediation analysis. Key Results 1266 hospitalized COVID-19 patients (60±15 years, 47.8% are male TRANS) were included, with an overall in-hospital death MESHD rate of 4.42% (56/1266). For critical cases, 77.02% had at least one preexisting comorbidity. Patients with comorbidities suffered higher in-hospital death MESHD and more severe decline of kidney function. Compared to patients with minor function decline (<10%), significant risk increase was found in those with more severe one (OR 3.57; 95%CI 1.70 to 7.52; P=.001 for moderate with 10-50% decline, and 37.45; 95%CI 18.71 to 74.55; P<.001 for severe with>50%). More interestingly, the mediation analysis found deteriorated kidney function played as an important mediator between different comorbidities and COVID-19 patients’ in-hospital death MESHD, with the mediation effect of 11%, 12%, 16% and 32% respectively for hypertension MESHD hypertension HP, COPD, CVD and CKD.Conclusions Deteriorated kidney function is strongly associated with increase of in-hospital death MESHD in COVID-19 and partially mediates the facilitating effect of preexisting comorbidities on in-hospital death MESHD. Thus, dynamic monitoring kidney function, preventing the deterioration of kidney function might be helpful to improve survival in COVID-19 patients, especially those with preexisting comorbidities.

    Objective: To examine the clinical characteristics and identify independent risk factors for in-hospital mortality of 2019 novel coronavirus (COVID-19) pneumonia MESHD pneumonia HP.Methods: A total of 156 patients diagnosed with COVID-19 pneumonia MESHD pneumonia HP at the central Hospital of Wuhan from January 29, 2020, to March 20, 2020 were enrolled in this single-centered retrospective study. Their epidemiological parameters, clinical presentations, underlying diseases MESHD, laboratory test results and disease MESHD outcomes were collected and analyzed. Results: The median age TRANS of enrolled patients was 66. Underlying diseases MESHD were identified in 101 patients, with hypertension MESHD hypertension HP being the most common one, followed by cardiovascular disease MESHD and diabetes. The most common symptoms identified upon admission were fever MESHD fever HP, cough MESHD cough HP, dyspnea MESHD dyspnea HP and fatigue MESHD fatigue HP. Compared to survival cases, patients who dead during hospitalization had higher plasma SERO levels of D-dimer, creatinine, creatine kinase, lactate dehydrogenase, lactate and lower percentage of lymphocytes (LYM [%]), platelet count and albumin levels. Most enrolled patients received anti-biotics and anti-viral treatment. In addition, 60 patients received corticosteroid and 51 received intravenous immunoglobulin infusion. 44 patients received noninvasive ventilation, 19 received invasive ventilation. Respiratory failure HP was the most frequently observed complication (106 [67.9%]), followed by sepsis MESHD sepsis HP (103 [66.0%]), acute respiratory distress HP syndrome MESHD (ARDS) (67 [42.9%]) and septic shock MESHD shock HP (50 [32.1%]). Multivariable regression suggested that advanced age TRANS (OR [odds ratio]= 1.059, 95% CI [confidence interval]: 1.011-1.110, P= 0.016) and elevated lactate level upon admission (OR= 2.411, 95% CI: 1.177-4.941, P= 0.016) were independent risk factors for in-hospital mortality for COVID-19 infection MESHD. Meanwhile, increased LYM (%) at admission (OR= 0.798, 95% CI: 0.728-0.876, P< 0.001) indicated a better prognosis. Conclusions: In this study, we discovered that age TRANS, LYM (%) and lactate level upon admission were independent factors that could influence in-hospital mortality rate.

    Introduction: Coronavirus disease MESHD-2019 (COVID-19), caused by severe acute respiratory syndrome MESHD coronavirus-2 (SARS-CoV-2), is causing dramatic morbidity and mortality worldwide. The Red Blood SERO Cell Distribution Width (RDW) has been strongly associated with increased morbidity and mortality in multiple diseases MESHD. Objective: To assess if elevated RDW is associated with unfavorable outcomes in hospitalized COVID-19. Methods: We retrospectively studied clinical outcomes of hospitalized COVID-19 patients for their RDW values. In-hospital mortality was defined as primary outcome, while septic shock MESHD shock HP, need for mechanical ventilation, and length of stay (LOS) were secondary outcomes. Results- A total of 294 COVID-19 patients were finally studied. Overall prevalence SERO of increased RDW was 49.7% (146/294). RDW was associated with increased risk of in-hospital mortality (aOR, 4.5; 95%CI, 1.4-14.3) and septic shock MESHD shock HP (aOR, 4.6; 95%CI, 1.4-15.1) after adjusting for anemia MESHD anemia HP, ferritin, and lactate. The association remained unchanged even after adjusting for other clinical confounders such as age TRANS, sex, body mass index, coronary artery disease MESHD, hypertension MESHD hypertension HP, diabetes mellitus MESHD diabetes mellitus HP, and chronic obstructive pulmonary disease MESHD chronic obstructive pulmonary disease HP. No association was found instead with mechanical ventilation and median LOS. Conclusion: Elevated RDW in hospitalized COVID-19 patients is associated with a significantly increased risk of mortality and septic shock MESHD shock HP.
