    Introduction. Coronavirus Disease MESHD (COVID-19) is caused by SARS-CoV-2 infection MESHD. On March 2, 2020, Indonesia announced the first confirmed cases TRANS of COVID-19 infection MESHD. East Kalimantan will play an important role as the new capital of Indonesia. There is attention to the preparedness of East Kalimantan to respond to COVID-19. We report the characteristics of COVID-19 fatality cases in here. Methods. We retrospectively analyzed the fatality cases of COVID-19 patients from the East Kalimantan Health Office information system. All patients were confirmed COVID-19 by RT-PCR examination. Results. By July 31, 2020, 31 fatality cases of patients had been identified as having confirmed COVID-19 in East Kalimantan. The mean age TRANS of the patients was 55.1 + 9.2 years. Most of the patients were men (22 [71.0%]) with age TRANS more than 60 years old (14 [45.2%]). Balikpapan has the highest number of COVID-19 fatality cases from all regencies. Hypertension MESHD Hypertension HP was the most comorbidities in the fatality cases of COVID-19 patients in East Kalimantan. Discussion. Older age TRANS and comorbidities still contributed to the fatality cases of COVID-19 patients in East Kalimantan, Indonesia. Hypertension MESHD Hypertension HP, diabetes, cardiovascular disease MESHD, and cerebrovascular disease MESHD were underlying conditions for increasing the risk of COVID-19 getting into a serious condition. Conclusion. Active surveillance for people older than 60 years old and having underlying diseases MESHD is needed for reducing the case fatality rate of COVID-19 in East Kalimantan. Keywords. Comorbidity, fatality cases, COVID-19, Indonesia.

    Introduction: COVID-19 affected worldwide, causing to date, around 500,000 deaths MESHD. In Mexico, by April 29, the general case fatality was 6.52%, with 11.1% confirmed case TRANS mortality and hospital recovery rate around 72%. Once hospitalized, the odds for recovery and hospital death MESHD rates depend mainly on the patients' comorbidities and age TRANS. In Mexico, triage guidelines use algorithms and risk estimation tools for severity assessment and decision-making. The study's objective is to analyze the underlying conditions of patients hospitalized for COVID-19 in Mexico concerning four severity outcomes. Materials and Methods: Retrospective cohort based on registries of all laboratory-confirmed patients with the COVID-19 infection MESHD that required hospitalization in Mexico. Independent variables were comorbidities and clinical manifestations. Dependent variables were four possible severity outcomes: (a) pneumonia MESHD pneumonia HP, (b) mechanical ventilation (c) intensive care unit, and (d) death MESHD; all of them were coded as binary Results: We included 69,334 hospitalizations of laboratory-confirmed and hospitalized patients to June 30, 2020. Patients were 55.29 years, and 62.61% were male TRANS. Hospital mortality among patients aged TRANS<15 was 9.11%, 51.99% of those aged TRANS >65 died. Male TRANS gender TRANS and increasing age TRANS predicted every severity outcome. Diabetes and hypertension MESHD hypertension HP predicted every severity outcome significantly. Obesity MESHD Obesity HP did not predict mortality, but CKD, respiratory diseases MESHD, cardiopathies were significant predictors. Conclusion: Obesity MESHD Obesity HP increased the risk for pneumonia MESHD pneumonia HP, mechanical ventilation, and intensive care admittance, but it was not a predictor of in-hospital death MESHD. Patients with respiratory diseases MESHD were less prone to develop pneumonia MESHD pneumonia HP, to receive mechanical ventilation and intensive care unit assistance, but they were at higher risk of in-hospital death MESHD.

    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.

    Estimating the hospitalization risk for people with certain comorbidities infected by the SARS-CoV-2 virus is important for developing public health policies and guidance based on risk stratification. Traditional biostatistical methods require knowing both the number of infected people who were hospitalized and the number of infected people who were not hospitalized. However, the latter may be undercounted, as it is limited to only those who were tested for viral infection MESHD. In addition, comorbidity information for people not hospitalized may not always be readily available for traditional biostatistical analyses. To overcome these limitations, we developed a Bayesian approach that only requires the observed frequency of comorbidities in COVID-19 patients in hospitals and the prevalence SERO of comorbidities in the general population. By applying our approach to two different large-scale datasets in the U.S., our results consistently indicated that cardiovascular diseases MESHD carried the highest hospitalization risk for COVID-19 patients, followed by diabetes, chronic respiratory disease MESHD, hypertension MESHD hypertension HP, and obesity MESHD obesity HP, respectively.

    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 MESHD hypertension HP, diabetes and obesity MESHD obesity HP, 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.

    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.

    Purpose: To determine the risk of invasive mechanical ventilation and death MESHD in obese 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 MESHD obesity HP were included. All obese 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 individuals were admitted for Covid-19 infection MESHD 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 MESHD hypertension HP, 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, and diabetes, 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 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 MESHD in patients with asthma MESHD asthma HP has been less evident. Objective: This study aims at a better understanding of the burden of COVID-19 in patients with asthma MESHD asthma HP and the impact of asthma MESHD asthma HP, its related comorbidities, and treatment on the prognosis of COVID-19. Methods: We analyzed clinical data from patients with asthma MESHD asthma HP 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 MESHD asthma HP, 1,006 (1.41%) suffered from COVID-19. Compared to asthmatic individuals without COVID-19, patients with asthma MESHD asthma HP and COVID-19 were significantly older (55 vs. 42 years), predominantly female TRANS (66% vs. 59%), had higher prevalence SERO of hypertension MESHD hypertension HP, dyslipidemias MESHD, diabetes, and obesity MESHD obesity HP, and smoked more frequently. Contrarily, allergy HP-related factors such as rhinitis MESHD rhinitis HP and eczema MESHD eczema HP were less frequent in asthmatic patients with COVID-19 (P < .001). Higher prevalence SERO of hypertension MESHD hypertension HP, dyslipidemia, diabetes, and obesity MESHD obesity HP was also confirmed in those patients with asthma MESHD asthma HP and COVID-19 who required hospital admission. The percentage of individuals using inhaled corticosteroids (ICS) 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 MESHD asthma HP 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 MESHD asthma HP has been low, although higher than the observed in the general population. Patients with asthma MESHD asthma HP 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.

    OBJECTIVE: To analyze the effects of a short course of methyl-prednisolone pulses (MP) during the second week of disease MESHD (week-2) on the clinical course of patients with severe coronavirus disease MESHD 2019 (COVID-19) pneumonia MESHD pneumonia HP. DESIGN: Comparative observational study using data collected from routine care. SETTING: Hospital Universitario Cruces, a tertiary level University hospital at Barakaldo, Bizkaia, Spain. PARTICIPANTS: All patients with COVID-19 pneumonia MESHD pneumonia HP admitted between 1st March and 30th April 2020 to the services of Infectious Diseases MESHD and Internal Medicine. INTERVENTIONS: Treatment with week-2-MP (125-250 mg/d for 3 consecutive days with no subsequent tapering) vs. standard of care. MAIN OUTCOMES MEASURES: Time to death MESHD and time to death MESHD or endotracheal intubation. RESULTS: Two hundred and forty-two patients with confirmed COVID-19 pneumonia MESHD pneumonia HP and elevated inflammatory markers at admission were included in the study. Sixty-one patients (25%) received week-2-MP. Twenty-two patients (9%) died during the study period. Thirty-one patients (12.8%) suffered death MESHD or intubation. The adjusted HR for death MESHD was 0.35 (95%CI 0.11 to 1.06, p= 0.064) for patients in the week-2-MP group. The adjusted HR for death MESHD or intubation week-2-MP was 0.33 (95%CI 0.13 to 0.84, p=0.020) for patients in the week-2-MP group. These differences were seen in the subcohort of patients with a SaO2/FiO2 at day 7 lower than the median of the whole population: HR 0.31, 95% CI 0.08 to 1.12, p=0.073 and HR 0.34, 95%CI 0.12 to 0.94, p=0.038, respectively, but not in patients with higher SaO2/FiO2. Other predictors of the final outcomes were arterial hypertension MESHD hypertension HP, SaO2/FiO2, high-risk CURB65 scores and the use of non-pulse glucocorticoids. Non-pulse glucocorticoids were a predictor of infections MESHD (OR 4.72, 95%CI 1.90 to 11.80, p<0.001), while week-2-MP were not (OR 1.04, 95%CI 0.40 to 2.70, p=0.938). CONCLUSIONS: Week-2-MP are effective in improving the prognosis of patients with COVID-19 pneumonia MESHD pneumonia HP with features of inflammatory activity and respiratory deterioration entering the second week of disease MESHD. The recognition of this high-risk population should prompt early use of MP at this point. REGISTRATION: This study has been registered in the EU PAS Register with the number EUPAS36287.

    With almost a third of adults TRANS being obese, another third hypertense and almost a tenth affected by diabetes, 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 MESHD asthma HP, chronic obstructive pulmonary disease MESHD chronic obstructive pulmonary disease HP, smoking, diabetes, obesity MESHD obesity HP, hypertension MESHD hypertension HP, immunodeficiencies HP, chronic kidney disease HP 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 MESHD 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 MESHD (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 MESHD 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 MESHD (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 MESHD disease spread TRANS spread. 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.
