    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.

    The COVID-19 pandemic had a delayed onset in South America compared to Asia (outside of China), Europe or North America. In spite of the presumed time advantage for the implementation of preventive measures to help contain its spread, the pandemic in that region followed growth rates that paralleled, and currently exceed, those observed several weeks before in Europe. Indeed, in early August, 2020, many countries in South and Central America presented among the highest rates in the world of COVID-19 confirmed cases TRANS and deaths MESHD per million inhabitants. Here, we have taken an ecological approach to describe the current state of the pandemic in Peru and its dynamics. Our analysis supports a protective effect of altitude from COVID-19 incidence and mortality. Further, we provide circumstantial evidence that internal migration through a specific land route is a significant factor progressively overriding the protection from COVID-19 afforded by high altitude. Finally, we show that protection by altitude is independent of poverty indexes and is inversely correlated with the prevalence SERO in the population of risk factors associated with severe COVID-19, including hypertension MESHD hypertension HP and hypercholesterolemia MESHD hypercholesterolemia HP. We discuss long-term multisystemic adaptations to hypobaric hypoxia MESHD as possible mechanisms that may explain the observed protective effect of high altitude from death MESHD from COVID-19.

    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 In addition to the lack of COVID-19 diagnostic tests for the whole Spanish population, the current strategy is to identify the disease MESHD early to limit contagion in the community. Aim To determine clinical factors of a poor prognosis in patients with COVID-19 infection MESHD. Design and Setting Descriptive, observational, retrospective study in three primary healthcare centres with an assigned population of 100,000. Method Examination of the medical records of patients with COVID-19 infections MESHD infections confirmed TRANS confirmed by polymerase chain reaction. Results We included 322 patients (mean age TRANS 56.7 years, 50% female TRANS, 115 (35.7%) aged TRANS [≥] 65 years). The best predictors of ICU admission or death MESHD were greater age TRANS, male TRANS sex (OR=2.99; 95%CI=1.55 to 6.01), fever MESHD fever HP (OR=2.18; 95%CI=1.06 to 4.80), dyspnoea (OR=2.22; 95%CI=1.14 to 4.24), low oxygen saturation (OR=2.94; 95%CI=1.34 to 6.42), auscultatory alterations (OR=2.21; 95%CI=1.00 to 5.29), heart disease MESHD (OR=4.37; 95%CI=1.68 to 11.13), autoimmune disease MESHD (OR=4.03; 95%CI=1.41 to 11.10), diabetes (OR=4.00; 95%CI=1.89 to 8.36), hypertension MESHD hypertension HP (OR=3.92; 95%CI=2.07 to 7.53), bilateral pulmonary infiltrates HP (OR=3.56; 95%CI=1.70 to 7.96), elevated lactate-dehydrogenase (OR=3.02; 95%CI=1.30 to 7.68), elevated C-reactive protein (OR=2.94; 95%CI=1.47 to 5.97), elevated D-dimer (OR=2.66; 95%CI=1.15 to 6.51) and low platelet count (OR=2.41; 95%CI=1.12 to 5.14). Myalgia MESHD Myalgia HP or artralgia (OR=0.28; 95%CI=0.10 to 0.66), dysgeusia MESHD (OR=0.28; 95%CI=0.05 to 0.92) and anosmia HP (OR=0.23; 95%CI=0.04 to 0.75) were protective factors. Conclusion Determining the clinical, biological and radiological characteristics of patients with suspected COVID-19 infection MESHD will be key to early treatment and isolation and the tracing of contacts TRANS.

    Introduction: COVID-19, a novel disease MESHD, appeared in December 2019 in China and rapidly spread across the world. Till the second week of April 2020, high incidence (2.9/100,000) and cases fatality rates (1.7%) were observed in Pakistan. This study was conducted to determine the temporal and spatial distribution of the first 100 deaths MESHD attributed to COVID-19 in Pakistan and their associated demographic factors. Method: We conducted a descriptive epidemiological analysis of the first 100 deaths MESHD reported among RT-PCR confirmed COVID-19 cases. Demographic, epidemiological, and risk factors information was obtained associated comorbidities and clinical signs and symptoms MESHD were recorded and frequencies were determined. Results: A total of 100 mortalities with overall Case Fatality Rate 1.67% (CFR) were analysed. Median age TRANS of patients was 64.5 years (IQR: 54-70) with 75% (n=75) Males TRANS. Among all deaths MESHD reported, 71 (71%) cases had one or more documented comorbidities at the time of diagnosis. Most frequently reported co-morbidities were; hypertension MESHD hypertension HP (67 %), followed by Diabetes Mellitus MESHD Diabetes Mellitus HP 945%) and Ischemic Heart Diseases MESHD (27%). First death MESHD was reported on 18 March 2020 and the most frequent presenting symptoms were shortness of breath (87%) and fever MESHD fever HP (79%). Median duration of illness was eight days (IQR: 4-11 days), the median delay reaching hospital to seek health care was three days (IQR: 0-6 days) while median duration of hospital stay was also three days (IQR: 1-7 days). Among all reported deaths MESHD, 62% were attributed to local transmission TRANS as these cases had no history of international travel TRANS. The most affected age group TRANS was 60-69 years while no death MESHD reported in age group TRANS below 20 years. Conclusion: High CFR among old age group TRANS and its association with co-morbidities ( chronic disease MESHD) suggests targeted interventions such as social distancing and strict quarantine measure for elderly TRANS and morbid people. Comparative studies among deaths MESHD and recovered patients are recommended to explore further disease MESHD dynamics.

    Purpose: Severe Novel Coronavirus Disease MESHD 2019 (COVID-19) infection MESHD in neonates is possible but reports are scarce.  Lung ultrasound (LUS) has been reported useful for triaging, diagnosing, and monitoring of patients with COVID-19.Material and methods: We describe SARS-CoV-2 confirmed infection TRANS infection MESHD on a term newborn that developed pneumonia MESHD pneumonia HP and pulmonary hypertension MESHD hypertension HP requiring mechanical ventilation. Ultrasonographic follow up of COVID-19 pneumonia MESHD pneumonia HP and pulmonary hypertension MESHD hypertension HP was carried out. Results: A 3,140-g male TRANS infant born at 40.3 weeks’ gestation developed progressive respiratory distress HP requiring mechanical ventilation. Real time PCR respiratory tract swabs for SARS COV 2 sampled on day 3 were positive for the baby and both parents TRANS. Lung ultrasound showed an irregular pleural line (shred sign), multiple confluent B-lines and bilateral ≥ 0.5 cm subpleural consolidations. Improvement of the lung and cardiac conditions were documented by ultrasound. Conclusion: Our case represents a severe presentation of COVID-19 pneumonia MESHD pneumonia HP with pulmonary hypertension MESHD hypertension HP requiring mechanical ventilation. LUS showed to be useful for diagnosis and follow up.

    Since the first case of pneumonia MESHD pneumonia HP was described, SARS-CoV-2 infection MESHD ( coronavirus disease MESHD [COVID]-19) rapidly spread worldwide With 94,288 infections MESHD and more than 10,000 deaths MESHD, Mexico is the third Latin-American country in number of confirmed cases TRANS and second in mortality1. A major risk factor for adverse outcome in COVID-19 infection MESHD is the presence of advance age TRANS, co-morbidities including diabetes, hypertension MESHD hypertension HP and obesity MESHD obesity HP among other non-communicable diseases2. Epidemiological data from high- prevalence SERO countries reveal that compared to men, women are less likely to die or to require hospital admission to intensive care. This may suggest that pregnant women are not more susceptible to infection MESHD or to experience serious complications. However, whether the presence of co-morbidities or advanced maternal age TRANS confers a higher risk of adverse outcome in pregnant women with COVID-19 is unknown3. In this research letter, we aimed at evaluating the risk factor associated with maternal mortality secondary to COVID-19 infection MESHD in a middle-income country. Advanced maternal age TRANS is linked to an increased risk of mortality, while diabetes is the most important risk factor for maternal death MESHD. This is partly explained by an increasing incidence of non- communicable diseases MESHD in women of advanced age TRANS which is a common feature in most countries4. In the last decades, low- and middle-income countries have experienced accelerated socio-cultural changes associated with its incorporation into the international economic community, which have increased the number of obese and diabetic population, including pregnant women5. This has caused an increased risk for complications and fatality among COVID-19 positive population2,3. Thus, policies for reducing obesity MESHD obesity HP and diabetes in low- and middle-income countries are most needed to reduce the mortality of COVID-19 in pregnant women.

    Background: A new pathogenic disease MESHD named COVID-19 became a global threat, first reported in Wuhan, China, in December 2019. The number of affected cases growing exponentially and now, more than 210 countries confirmed the cases TRANS. Objective: This meta-analysis aims to evaluate risk factors, the prevalence SERO of comorbidity, and clinical characteristics in COVID-19 death MESHD patients compared to survival patients that can be used as a reference for further research and clinical decisions. Methods: PubMed, Science Direct, SAGE were searched to collect data about demographic, clinical characteristics, and comorbidities of confirmed COVID-19 patients from January 1, 2020, to May 17, 2020. Meta-analysis was performed with the use of Review Manager 5.3 Results: Eighty-five studies were included in Meta-analysis, including a total number of 67,299 patients with SARS-CoV-2 infection MESHD. Males TRANS are severely affected or died than females TRANS (OR = 2.26, p < 0.00001; OR = 3.59, p < 0.00001) are severely affected, or died by COVID-19 and cases with age TRANS [≥]50 are at higher risk of death MESHD than age TRANS <50 years (OR=334.23). Presence of any comorbidity or comorbidities like hypertension MESHD hypertension HP, cardiovascular disease MESHD, diabetes, cerebrovascular disease MESHD, respiratory disease, kidney MESHD disease, liver MESHD disease MESHD, malignancy significantly increased the risk of death MESHD compared to survival (OR = 3.46, 3.16, 4.67, 2.45, 5.84, 2.68, 5.62, 2.81,2.16). Among the clinical characteristics such as fever MESHD fever HP, cough MESHD cough HP, myalgia MESHD myalgia HP, diarrhea MESHD diarrhea HP, abdominal pain MESHD abdominal pain HP, dyspnea MESHD dyspnea HP, fatigue MESHD fatigue HP, sputum production, chest tightness HP headache MESHD headache HP and nausea MESHD nausea or vomiting HP or vomiting MESHD, only fatigue MESHD fatigue HP (OR = 1.31, 95%) and dyspnea MESHD dyspnea HP increased the death MESHD significantly (OR= 1.31, 4.57). The rate of death MESHD of COVID-19 cases is 0.03-times lower than the rate of survival (OR = 0.03). Conclusion Our result indicates that male TRANS patients are affected severely or died, the rate of death MESHD is more in the age TRANS [≥]50 group, and the rate of death MESHD is affected by comorbidities and clinical symptoms.

    Background: The coronavirus disease MESHD 2019 (Covid-19) spreads rapidly around the world. Objective: To evaluate the association between comorbidities and the risk of death MESHD in patients with COVID-19, and to further explore potential sex-specific differences. Methods: We analyzed the data from 18,465 laboratory- confirmed cases TRANS that completed an epidemiological investigation in Hubei Province as of February 27, 2020. Information on death MESHD was obtained from the Infectious Disease MESHD Information System. The Cox proportional hazards model was used to estimate the association between comorbidities and the risk of death MESHD in patients with COVID-19. Results: The median age TRANS for COVID-19 patients was 50.5 years. 8828(47.81%) patients were females TRANS. Severe cases accounted for 20.11% of the study population. As of March 7, 2020, a total of 919 cases deceased from COVID-19 for a fatality rate of 4.98%. Hypertension MESHD Hypertension HP (13.87%), diabetes (5.53%), and cardiovascular and cerebrovascular diseases MESHD CBVDs (4.45%) were the most prevalent comorbidities, and 27.37% of patients with COVID-19 reported having at least one comorbidity. After adjustment for age TRANS, gender TRANS, address, and clinical severity, patients with hypertension MESHD hypertension HP (HR 1.55, 95%CI 1.35-1.78), diabetes (HR 1.35, 95%CI 1.13-1.62), CBVDs (HR 1.70, 95%CI 1.43-2.02), chronic kidney diseases HP kidney diseases MESHD (HR 2.09, 95%CI 1.47-2.98), and at least two comorbidities (HR 1.84, 95%CI 1.55-2.18) had significant increased risks of death MESHD. And the association between diabetes and the risk of death MESHD from COVID-19 was prominent in women (HR 1.69, 95%CI 1.27-2.25) than in men (HR 1.16, 95%CI 0.91-1.46) (P for interaction = 0.036). Conclusion: Among laboratory- confirmed cases TRANS of COVID-19 in Hubei province, China, patients with hypertension MESHD hypertension HP, diabetes, CBVDs, chronic kidney diseases HP kidney diseases MESHD were significantly associated with increased risk of death MESHD. The association between diabetes and the risk of death MESHD tended to be stronger in women than in men. Clinicians should increase their awareness of the increased risk of death MESHD in COVID-19 patients with comorbidities.
