    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 HP hypertension MESHD, coronary artery disease MESHD, history of stroke HP stroke MESHD, diabetes MESHD, obesity HP obesity MESHD [BMI [≥]30 kg/m2], severe obesity HP obesity MESHD [BMI[≥]40 kg/m2], chronic kidney disease HP chronic kidney disease MESHD, asthma HP asthma MESHD, and chronic obstructive pulmonary disease HP chronic obstructive pulmonary disease MESHD). Results: Our sample included 5,416 adults TRANS with COVID-19-associated hospitalizations. Adults TRANS with (versus without) severe obesity HP obesity MESHD (aRR:4.4; 95%CI: 3.4, 5.7), chronic kidney disease HP chronic kidney disease MESHD (aRR:4.0; 95%CI: 3.0, 5.2), diabetes MESHD (aRR:3.2; 95%CI: 2.5, 4.1), obesity HP obesity MESHD (aRR:2.9; 95%CI: 2.3, 3.5), hypertension HP hypertension MESHD (aRR:2.8; 95%CI: 2.3, 3.4), and asthma HP asthma MESHD (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 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 (aggravation) cases. The aggravation cases tend to have more medical comorbidity: hypertension HP hypertension MESHD (34.1%), diabetes MESHD (30.7%), and presented with dyspnea HP dyspnea MESHD (34.1%), neutrophilia HP (60.2%), and lymphocytopenia MESHD (73.9%), compared with those without. And the patients with disease progression 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 HP lymphopenia MESHD, and elevated level of Fbg, lactate dehydrogenase (LDH), Cardiac troponin (CTnI), IL-6, serum SERO ferritin were the significant predictors of disease progression. 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 cases compared to non-progression cases from 3 weeks after symptom onset TRANS. In addition, the disease progression 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 Understanding risk factors for death MESHD in Covid 19 is key to providing good quality clinical care. Due to a paucity of robust evidence, we sought to assess the presenting characteristics of patients with Covid 19 and investigate factors associated with death MESHD. Methods Retrospective analysis of adults TRANS admitted with Covid 19 to Royal Oldham Hospital, UK. Logistic regression modelling was utilised to explore factors predicting death. Results 470 patients were admitted, of whom 169 (36%) died. The median age TRANS was 71 years (IQR 57 to 82), and 255 (54.3%) were men. The most common comorbidities were hypertension HP hypertension MESHD (n=218, 46.4%), diabetes MESHD (n=143, 30.4%) and chronic neurological disease MESHD (n=123, 26.1%). The most frequent complications were acute kidney injury HP acute kidney injury MESHD (n=157, 33.4%) and myocardial injury MESHD (n=21, 4.5%). Forty three (9.1%) patients required intubation and ventilation, and 39 (8.3%) received non-invasive ventilation Independent risk factors for death MESHD were increasing age TRANS (OR per 10 year increase above 40 years 1.87, 95% CI 1.57 to 2.27), hypertension HP hypertension MESHD (OR 1.72, 1.10 to 2.70), cancer MESHD (OR 2.20, 1.27 to 3.81), platelets <150x103/microlitre (OR 1.93, 1.13 to 3.30), C-reactive protein >100 micrograms/mL (OR 1.68, 1.05 to 2.68), >50% chest radiograph infiltrates, (OR 2.09, 1.16 to 3.77) and acute kidney injury HP acute kidney injury MESHD (OR 2.60, 1.64 to 4.13). There was no independent association between death MESHD and gender TRANS, ethnicity, deprivation level, fever HP fever MESHD, SpO2/FiO2 (oxygen saturation index), lymphopenia HP lymphopenia MESHD or other comorbidities. Conclusions We characterised the first wave of patients with Covid 19 in one of Englands highest incidence areas, determining which factors predict death. These findings will inform clinical and shared decision making, including the use of respiratory support and therapeutic agents.

    Importance: Assessment of the use of angiotensin receptor blockers (ARBs) in the United States provides insight into prescribing practices, and may inform guidelines, policy measures and research during the COVID-19 pandemic. Objective: To evaluate trends in ARB use among adults TRANS in the United States who have preexisting conditions and sociodemographic risk factors that put them at a higher risk of SARS-CoV-2 infection MESHD and COVID-19-related complications and mortality. Design, setting and participants: This study uses the nationally representative cross-sectional data from the 2005-2018 National Health and Nutrition Examination Survey (NHANES). Participants included 39,749 non-institutionalized U.S. civilian adults TRANS who were 20 years and older and those with the most common preexisting conditions and risk factors reported among patients with COVID-19. Main outcomes and measures: Use of ARBs in the prior 30 days from survey interview. Results: ARB use ranged from 7.4% [95% CI, 6.5%-8.4%] to 26.2% [95% CI, 19.4%-34.4%] among those with one or two metabolic, renal, respiratory, and/or cardiovascular diseases MESHD. Among individuals with the three most common preexisting conditions in patients with COVID-19 including hypertension HP hypertension MESHD, diabetes MESHD and obesity HP obesity MESHD, ARB use was higher among the elderly TRANS, females TRANS, non-Hispanic whites, and those with health insurance coverage. Conclusions and relevance: In this nationally representative survey, ARB use was found to be widespread, but unevenly distributed among individuals with conditions and sociodemographic risk factors that place them at a higher risk of COVID-19 morbidity and mortality.

    Purpose: To determine the risk of invasive mechanical ventilation and death MESHD in obese MESHD individuals with history of bariatric surgery compared to standard ones admitted for Covid-19 infection MESHD.Methods: Nationwide retrospective observational study based on electronic health data. 4 248 253 individuals aged TRANS 15 to 75 years with a diagnosis of obesity HP obesity MESHD were included. All obese MESHD inpatients, undergoing bariatric surgery or not, recorded during a hospital stay by the French National Health Insurance were followed, during a mean observation time of 5.43 ± 2.93 years. This exposition was bariatric surgery (n=389,671) including adjustable gastric banding, sleeve gastrectomy, gastric bypass versus no bariatric surgery (n=3,858,582). The primary outcome was Covid-19 related death MESHD and the secondary outcome was the need for invasive mechanical ventilation.Results: 8 286 (0.2%) obese MESHD individuals were admitted for Covid-19 infection between January 1st and May 15th 2020 with a diagnosis of Covid-19 infection MESHD. 541 (0.14%) had a history of bariatric surgery and 7,745 (0.2%) did not. Invasive mechanical ventilation was necessary in 14.54% of patients and death MESHD occurred in 13.58% of cases. The need for an invasive mechanical ventilation and death MESHD occurred in 7% and 3.5% in the bariatric surgery group versus 15% and 14.2% in the non-bariatric surgery group, respectively (both p<0.0001). After a logistic regression, the risk of invasive mechanical ventilation significantly increased with age TRANS being higher in the age TRANS class 61-75, male TRANS gender TRANS, and hypertension HP hypertension MESHD, whereas bariatric surgery showed an independent protective effect. Mortality was independently associated with increasing age TRANS, male TRANS gender TRANS, known history of heart failure MESHD, cancer MESHD, and diabetes MESHD, whereas BS was in favor with a protective effect. Conclusion: This nationwide administrative study showed that bariatric surgery is independently associated with a reduced risk of death MESHD and invasive mechanical ventilation in obese MESHD individuals with Covid-19 infection MESHD.

    Background: From the onset of the COVID-19 pandemic, an association between the severity of COVID-19 and the presence of certain medical chronic conditions has been suggested. However, unlike influenza and other viruses, the burden of the disease in patients with asthma HP asthma MESHD has been less evident. Objective: This study aims at a better understanding of the burden of COVID-19 in patients with asthma HP asthma MESHD and the impact of asthma HP, its related comorbidities, and treatment on the prognosis of COVID-19. Methods: We analyzed clinical data from patients with asthma HP asthma MESHD from January 1st to May 10th, 2020 using big data analytics and artificial intelligence through the SAVANA Manager clinical platform. Results: Out of 71,192 patients with asthma HP asthma MESHD, 1,006 (1.41%) suffered from COVID-19. Compared to asthmatic individuals without COVID-19, patients with asthma HP asthma MESHD and COVID-19 were significantly older (55 vs. 42 years), predominantly female TRANS (66% vs. 59%), had higher prevalence SERO of hypertension HP hypertension MESHD, dyslipidemias MESHD, diabetes MESHD, and obesity HP obesity MESHD, and smoked more frequently. Contrarily, allergy HP allergy MESHD-related factors such as rhinitis HP rhinitis MESHD and eczema HP eczema MESHD were less frequent in asthmatic patients with COVID-19 (P < .001). Higher prevalence SERO of hypertension HP hypertension MESHD, dyslipidemia MESHD, diabetes MESHD, and obesity HP obesity MESHD was also confirmed in those patients with asthma HP asthma MESHD and COVID-19 who required hospital admission. The percentage of individuals using inhaled corticosteroids ( ICS MESHD) was lower in patients who required hospitalization due to COVID-19, as compared to non-hospitalized patients (48.3% vs. 61.5%; OR: 0.58: 95% CI 0.44-0.77). During the study period, 865 (1.21%) patients with asthma HP asthma MESHD were being treated with biologics. Although these patients showed increased severity and more comorbidities at the ear, nose, and throat (ENT) level, their hospital admission rates due to COVID-19 were relatively low (0.23%). COVID-19 increased inpatient mortality in asthmatic patients (2.29% vs 0.54%; OR 2.29: 95% CI 4.35-6.66). Conclusion: Our results indicate that the number of COVID-19 cases in patients with asthma HP has been low, although higher than the observed in the general population. Patients with asthma HP asthma MESHD and COVID-19 were older and were at increased risk due to comorbidity-related factors. ICS and biologics are generally safe and may be associated with a protective effect against severe COVID-19 infection MESHD.

    Coronaviruses are a family of related viruses that cause diseases in mammals and avians. Guillain-Barre syndrome MESHD is a rare disorder in which the body's immune system attacks peripheral nerves.The case:A 65 years old Sudanese male TRANS with no diabetes mellitus HP diabetes mellitus MESHD or hypertension HP hypertension MESHD present to the clinic; On examination, he has upper and lower limb weakness MESHD ( quadriplegia MESHD). The condition was preceded by upper respiratory tract infection HP respiratory tract infection MESHD. Chest X-ray showed features of pneumonia HP pneumonia MESHD Chest CT scan showed multiple bilateral ground-glass opacities and consolidation typical of COVID-19 pneumonia HP pneumonia MESHD. Brain MRI was normal. The COVID-19 nasal swab test was positive. Nerve conduction study showed evidence of polyradiculopathies MESHD with dominant demyelination MESHD supporting the diagnosis of Guillain-Barre syndrome MESHD. The patients died after seven days; because of progressive respiratory failure HP respiratory failure MESHD.

    Background In December 2019, coronavirus disease MESHD 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 MESHD (SARS-CoV-2) emerged in Wuhan, Hubei, China. And, it has become a global pandemic. Describe the patient's clinical symptoms in detail, finding markers that predict the prognosis of patients with COVID-19 are of great value.MethodsIn this multicenter, retrospective study, 476 patients with COVID-19 were recruited from a consecutive series. After screening, a total of 395 patients were included in this study. All-cause death MESHD was the primary endpoint. All patients were followed up from admission till discharge or death MESHD.ResultsThe dominant symptoms observed in the study included fever HP fever MESHD on admission, cough HP, fatigue HP fatigue MESHD and shortness of breath MESHD. The most frequent comorbidities were hypertension HP hypertension MESHD and diabetes MESHD. Compared with patients with higher CD4+T cells level, patients with lower CD4+T cells level were older and were more frequently male TRANS. In terms of laboratory findings, lymphocyte count, CD4+T cell count, CD8+T cell count were significantly lower in low group than in higher group. The case in-hospital death rate was significant higher in patients with lower CD4+T level. After adjusting for potential confounding factors, CD4+T count below the lower limit of normal showed independent prognostic value for all-cause in-hospital death MESHD in patients with COVID-19. Conclusions: Reductions in lymphocytes and lymphocyte subsets are common in COVID-19 patients, especially in severe cases. It is the CD8+T count, not the CD4+T count, that reflected the severity of the patient’s disease. Lower CD4+T count is independently associated with an increased rate of in-hospital death.

    With almost a third of adults TRANS being obese MESHD, another third hypertense MESHD and almost a tenth affected by diabetes MESHD, Latin American countries could see an elevated number of severe COVID-19 outcomes. We used the Open Dataset of Mexican patients with COVID-19 suspicion who had a definite RT-PCR result to develop a statistical model that evaluated the progression of SARS-CoV-2 infection MESHD in the population. We included patients of all ages TRANS with every risk factor provided by the dataset: asthma HP, chronic obstructive pulmonary disease HP chronic obstructive pulmonary disease MESHD, smoking, diabetes MESHD, obesity HP obesity MESHD, hypertension HP hypertension MESHD, immunodeficiencies HP immunodeficiencies MESHD, chronic kidney disease HP chronic kidney disease MESHD, cardiovascular diseases MESHD, and pregnancy. The dataset also included an unspecified category for other risk factors that were not specified as a single variable. To avoid excluding potential patients at risk, that category was included in our analysis. Due to the nature of the dataset, the calculation of a standardized comorbidity index was not possible. Therefore, we treated risk factors as a categorical variable with two categories: absence of risk factors and the presence of at least one risk factor in accordance with previous epidemiological reports. Multiple logistic regressions were carried out to associate sex, risk factors, and age TRANS as a continuous variable (and the interaction that accounted for increasing diseases with older ages TRANS); and SARS-CoV-2 infection MESHD as the dependent zero-one binomial variable. Post estimation predictive marginal analysis was performed to generate probability trends along 95% confidence bands. This analysis was repeated several times through the course of the pandemic since the first record provided in their repository (April 12, 2020) to one month after the end of the state of sanitary emergency (the last date analyzed: June 27, 2020). After processing, the last measurement included 464,389 patients. The baseline analysis on April 12 revealed that people 35 years and older with at least one risk factor had a lower risk of SARS-CoV-2 infection MESHD in comparison to patients without risk factors (Figure 1). One month before the end of the nationwide state of emergency this age TRANS threshold was found at 50 years (May 2, 2020) and it shifted to 65 years on May 30. Two weeks after the end of the public emergency (June 13, 2020) the trends converged at 80 years and one week later (June 27, 2020) every male TRANS and female TRANS patient with at least one risk factor had a higher risk of SARS-CoV-2 infection MESHD compared to people without risk factors. Through the course of the COVID-19 pandemic, all four probability curves shifted upwards as a result of progressive disease spread TRANS. In conclusion, we found our model could monitor accurately the probability of SARS-CoV-2 infection MESHD in relation to age TRANS, sex, and the presence of at least one risk factor. Also, because the model can be applied to any particular political region within Mexico, it could help evaluate the contagion spread in specific vulnerable populations. Further studies are needed to determine the underlying nature of the mechanisms behind such observations.

    Background: Coronavirus disease 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 has a multitude of clinical presentations, and especially the development of acute kidney injury HP acute kidney injury MESHD has been associated with increased mortality.Case Presentation: A 71-year old Caucasian male TRANS was admitted with fever HP fever MESHD and dyspnea HP dyspnea MESHD to the emergency department. His medical history included type 2 diabetes MESHD and hypertension HP hypertension MESHD. 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 respiratory failures MESHD and transferred to the intensive care ward where he developed acute anuric kidney failure MESHD 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 MESHD 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.
