ABSTRACT
Objective: To analyze and compare the effects of different clinical characteristics on the negative conversion time of nucleic acid detection after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant infection, and to provide a scientific basis for the isolation and treatment of coronavirus disease 2019 (COVID-19). Methods: The epidemiological and clinical data of 228 mild SARS-CoV-2 Omicron variant infected patients diagnosed in Shanghai were retrospectively collected from April 27, 2022 to June 8, 2022 in Wujiaochang designated Hospital, Yangpu District, Shanghai. The negative conversion time of nucleic acid detection was used as the outcome variable, and the patients were divided into A (18 days) and B (>18 days). Univariate and multivariate logistic regression analysis were used to analyze the influencing factors of the negative conversion time of nucleic acid detection. Results: The mean nucleic acid conversion time of 228 patients was (18.7+or-12.1) d, with the median time of 18 (2-46) d. Among them, 120 patients in group A had an average nucleic acid conversion time of (13.2+or-2.0) d, and 108 cases in group B had an average nucleic acid conversion time of (20.8+or-1.3) d. Univariate analysis showed that there were no statistically significant differences in the effects of hypertension, coronary heart disease, diabetes, hypokalemia, malignant tumors, neuropsychiatric diseases, chronic digestive diseases on the negative nucleic acid conversion time (P > 0.05);however, there were significant differences in the effects of combined cerebrovascular disease, leukopenia, chronic respiratory system diseases and vaccination on the negative nucleic acid conversion time (P < 0.05). Further multivariate logistic regression analysis revealed that the combination of chronic respiratory diseases and non-vaccination were significant risk factors for prolongation of negative nucleic acid conversion time (P < 0.05). Conclusions: The results of this study show that gender, age and whether hypertension, coronary heart disease, diabetes mellitus, hypokalemia, malignant tumor, neuropsychiatric disease and chronic digestive disease have no significant effect on the nucleic acid conversion time, whereas chronic respiratory disease and no vaccination are significantly correlated with the prolongation of nucleic acid conversion time in SARS-CoV-2 Omicron-infected patients.
ABSTRACT
Non-invasive ventilation (NIV) might be successful if carefully selected in adult patients with cardiac dysfunction presenting with community-acquired pneumonia. The main objective of this study was to identify the early predictors of NIV failure. Adult patients with left ventricle ejection fraction (LV EF) <50% admitted to the intensive care unit (ICU) with community-acquired pneumonia and acute respiratory failure were enrolled in this multicenter prospective study after obtaining informed consents (study registrationID: ISRCTN14641518). Non-invasive ventilation failure was defined as the requirement of intubation after initiation of NIV. All patients were assessed using the Acute Physiology and Chronic Health Evaluation II (APACHE II) and sequential organ failure assessment (SOFA) scores at admission, while their Heart rate Acidosis Consciousness Oxygenation and Respiratory rate (HACOR) and lung ultrasound (LUS) scores in addition to blood lactate were assessed at NIV initiation and 12 and 24 hours later. A total of 177 patients were prospectively enrolled from February 2019 to July 2020. Of them, 53 (29.9%) had failed NIV. The mean age of the study cohort was 64.1+or- 12.6 years, with a male predominance (73.4%) and a mean LV EF of 36.4 +or- 7.8%. Almost 55.9% of the studied patients had diabetes mellitus, 45.8% had chronic systemic hypertension, 73.4% had ischemic heart disease, 20.3% had chronic kidney disease, and 9.6% had liver cirrhosis. No significant differences were observed between the NIV success and NIV failure groups regarding underlying morbidities or inflammatory markers. Patients who failed NIV were significantly older and had higher mean SOFA and APACHE II scores than those with successful NIV. We also found that NIV failure was associated with longer ICU stay (p < 0.001), higher SOFA scores at 48 hours (p < 0.001) and higher mortality (p < 0.001) compared with the NIV success group. In addition, SOFA (Odds Ratio (OR): 4.52, 95% Confidence Interval (CI): 2.59-7.88, p < 0.001), HACOR (OR: 2.01, 95% CI: 0.97-4.18, p = 0.036) and LUS (OR: 1.33, 95% CI: 1.014-1.106, p = 0.027) scores and blood lactate levels (OR: 9.35, 95% CI: 5.32-43.26, p < 0.001) were independent factors for NIV failure. High initial HACOR and SOFA scores, persistent hyperlactatemia and non-decrementing LUS score were associated with early NIV failure in patients with cardiac dysfunction presenting with community-acquired pneumonia, and could be used as clinical and paraclinical variables for early decision making regarding invasive ventilation.

ABSTRACT
The article is devoted to the global problems of modern medicine - HIV infection and the COVID-19 pandemic. The review of the literature highlights current ideas about the pathogenesis and course of COVID-19 in patients with HIV infection, and also touches upon the problems of concomitant pathology and mental health of patients with HIV in the setting of the COVID-19 pandemic. It has been shown that HIV-positive patients are a risk group for the severe course of COVID-19, in particular, individuals with severe immunodeficiency (CD4+ T lymphocytes 200 cells/l) due to the development of synergetic lung damage by SARS-CoV-2 and secondary infectious agents such as cytomegalovirus and Pneumocystis carinii. It has been proven that one of the targets of the SARS-CoV-2 virus is CD4+ T cells, which in COVID-19 leads to a more rapid progression of immunodeficiency in patients with HIV infection and, thus, significantly increases the risk of secondary diseases and death. Particular attention should be paid to middle-aged and elderly people living with HIV, who, compared with HIV-negative patients, are more likely to have concomitant pathology - arterial hypertension, cardiomyopathy and diabetes mellitus, which are the risk factors for severe COVID-19. The results of studies on the effect of antiretroviral drugs on the course of COVID-19 showed that HIV-infected patients receiving tenofovir + emtricitabine have a lower risk of severe COVID-19 and associated hospitalization than patients receiving other HIV treatment regimens. Clinical and preclinical data support the potential use of tenofovir in the treatment of novel coronavirus infection.
ABSTRACT
Objective: To analyze the viral shedding time and its influencing factors in different site samples of patients infected with severe acute respiratory syndrome coronavirus 2 (SARA-CoV-2) omicron BA.2 variant. Methods: Real-time fluorescence polymerase chain reaction was used to detect SARS-CoV-2 nucleic acid in nasopharyngeal swab, sputum and anal swab from 217 patients with coronavirus disease 2019 (COVID-19) who were infected with severe acute respiratory syndrome coronavirus 2 omicron BA.2 variant confirmed by gene sequencing in The First Affiliated Hospital of Naval Medical University (Second Military Medical University). The differences of viral shedding time of different site samples were compared. Stratified analysis and multiple linear regression analysis were used to explore the influencing factors of viral shedding time in different site samples. Results: The age of the 217 COVID-19 patients was 32.0 (24.0, 50.5) years old, 59.0% of them were males (n=128), and 41.0% were females (n=89). Eight (3.7%) cases were diagnosed with asymptomatic infection, 184 (84.8%) cases were mild type, 21 (9.7%) cases were moderate type, 3 (1.4%) cases were severe type, and 1 (0.5%) case was critical type. A total of 70 (32.3%) patients were treated with molnupiravir. The viral shedding time of SARS-CoV-2 nucleic acid in nasopharyngeal swab, sputum and anal swab was 13.0 (11.0, 17.0) d, 16.5 (13.0, 21.0) d and 10.0 (5.3, 11.0) d, respectively, with the differences being significant between them (all P<0.001). Age 60 years old, underlying diseases (especially hypertension, coronary artery diseases, or neurological diseases), and clinical classification of moderate type were risk factors for prolonged viral shedding time in nasopharyngeal swab;male sex and underlying diseases were risk factors for prolonged viral shedding time in sputum;and male sex was a risk factor for prolonged viral shedding time in anal swab. Multiple linear regression analysis showed that critical type was an independent risk factor for prolonged viral shedding time in nasopharyngeal swab (P<0.05), and male sex and underlying diseases were independent risk factors for prolonged viral shedding time in sputum (both P<0.05). Conclusion: Among patients infected with omicron BA.2 variant, the viral shedding time in sputum is the longest and that in anal swab is the shortest. Male patients and/or patients with underlying diseases have longer viral shedding time in sputum.
ABSTRACT
Introduction: Considering that the new corona virus (COVID -19) is still prevalent, one of the important concerns is the variables affecting the severity of the corona disease in the health of society. In this study, the CART algorithm was fitted to predict and determine the status of patients infected with COVID-19 in Mashhad University of Medical Sciences. Methods: This paper is a cross sectional-analytical study. Datasets were obtained from all of the people referred for the disease of COVID -19 collected at the Sinai system during the second peak and the fourth peak of the disease in Mashhad University of Medical Sciences. Data analysis was performed using JMP statistical software version 13. Then for modeling, data mining methods and CART algorithm are used. Results: The descriptive findings of our study showed that 6% of patients with positive PCR suffer from severe disease of COVID-19. The age variable was very important in the severity of the disease. The age of 60 years old is the cut-off point for the severity of the disease, which increases COVID-19 severe from about 3% under the age of 60 to about 18% over the age of 60. The diseases of heart, kidney, respiratory, blood fat, and diabetes were other important variables. Conclusion: The results of the CART model showed that for the age under 60 years the variables of heart disease, age, diabetes, respiratory disease, fat, gender, and kidney, and for the age over 60 years the variables of age, heart disease, kidney, respiratory and diabetes were respectively the most critical risk factors. According to the ROC curve, the fitted model has a good performance for COVID-19 severe disease, so it increases up to 6 times the prediction of the COVID-19 severe disease.
ABSTRACT
The data of the modern literature describing the long-term consequences of infection of the body with SARS-CoV-2 on the cardiovascular system in the framework of postcovid syndrome are analyzed. To date, postcovid syndrome refers to a condition in which symptoms continue to persist for more than 12 weeks from the moment of diagnosis of COVID-19. Various complaints of patients after undergoing a new coronavirus infection are described, the distinguishing feature of which is their versatility, where cardiovascular manifestations are assigned one of the leading roles. Postural orthostatic tachycardia syndrome, cardiac arrhythmia and conduction disorders are considered. The role of SARS-CoV-2 in the formation of de novo and decompensation of pre-existing cardiovascular diseases has been demonstrated. The possibility of developing heart failure in patients with COVID-19 as an outcome of inflammation of the heart muscle is shown. Particular attention is paid to the analysis of the incidence of myocarditis after 3 months or more from the diagnosis of COVID-19, as well as thrombotic complications, in the genesis of which the main role belongs to the formation of endothelial dysfunction resulting from the interaction of SARS-CoV-2 with vascular endothelial cells. The autoimmune component of the pathogenesis of damage to the cardiovascular system as a result of the formation of endothelial dysfunction in COVID-19 is also considered. The authors present a laboratory-instrumental algorithm for determining cardiovascular complications in people who have undergone COVID-19, including the determination of the N-terminal fragment of the brain natriuretic peptide B-type prohormone, the level of anticardial antibodies, electrocardiography, echocardiography, as well as magnetic resonance imaging of the heart with contrast.
ABSTRACT
Introduction: Acute recurrent purulent pericarditis is an uncommon pericardium infection that can be life-threatening due to pus production, leading to cardiac tamponade. Case presentation: We report a 36-year-old man referring to our hospital with impending cardiac tamponade who needed urgent pericardiocentesis. The patient's complaints were worsening dyspnea and palpitations in the last two days. The patient had been hospitalized for the same complaint and had pericardiocentesis due to cardiac tamponade approximately three weeks earlier. Physical exam, ECG, and CXR suggest impending cardiac tamponade. Echocardiography indicated massive right and left pericardial effusion and right atrial collapse. The Covid-19 screening test was positive;however, RT-PCR revealed a negative result. The patient was diagnosed with recurrent acute purulent pericarditis with impending cardiac tamponade requiring urgent pericardiocentesis. After the procedure, 1.5 million units of intrapericardial fibrinolytic were administered to patients. His improved hemodynamic and clinical symptoms indicate a successful procedure. Conclusion: This case highlights the challenges of managing an acute recurrent purulent pericarditis patient due to Staphylococcus A. infection in the current pandemic era, including distinguishing it from other contagious diseases due to nonspecific dyspnea, limited therapeutic options, and the effectiveness of intrapericardial fibrinolytic in improving the overall patient conditions, and reducing the mortality rate.
ABSTRACT
The provision of cardiac surgery services nationwide has been affected by the COVID-19 pandemic. We noticed a high COVID-19 mortality rate in unvaccinated patients who were diagnosed with COVID-19 after recent cardiac surgery. All the patients were tested negative for COVID-19 before surgery. We conducted a review of our hospital data and reported our findings. We identified 15 patients and reported 7 deaths (46.7%). All the patients died from COVID-19 or its complications. We recommend that cardiac centres actively promote vaccination before cardiac surgery and also enhance infection control measures to prevent nosocomial infections.
ABSTRACT
Background: Severe acute respiratory illness due to SARS-CoV-2 represents great global public health concern. The spectrum of disease ranges from mild to life-threatening. Surveillance of hospitalized patients with severe acute respiratory infections (SARI) is an important public health tool used to identify etiologies to understand the disease, track changes in circulating viruses and as an alert mechanism for potential pandemic viruses. We aim to find out the rate of SARS-CoV-2 positivity in SARI cases and further study the epidemiological and clinical characteristics of patients. Material & Methods: A Prospective study was conducted on 200 Severe Acute Respiratory Illness patients admitted at tertiary care hospital. The clinical, demographic, epidemiological, risk factors / co-morbidities of all the patients were recorded. Oropharyngeal and nasopharyngeal samples were collected and tested for SARS-CoV-2 by real time reverse transcriptase (RT-PCR) test. Results: Out of 200 SARI patients, 51 (25.5%) were tested positive for SARS-CoV-2. Maximum cases (54.90%) were in the age group of 41-60 years;males were infected predominantly (52.94%). The most common symptoms of presentation were fever (100%), cough (86.27%), dyspnoea (82.35%) and sore throat (56.86%). Comorbidities associated with COVID-19 were Hypertension (56.86%), Diabetes Mellitus (33.33%), Chronic Obstructive Pulmonary Disease (13.72%) and Coronary Artery disease (9.8%). More than 30% of the patients were admitted in ICU and 9.80% received mechanical ventilation. Conclusions: Evaluation of clinical and epidemiological profiles of SARI patients can help in understanding and managing the outbreak more efficiently. Close monitoring and quarantine will be required to prevent extensive transmission within the community.
ABSTRACT
Objective: To investigate the clinical significance of serum interleukin 6 (IL-6) in elderly patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) omicron variant and its correlation with underlying diseases. Methods: A total of 22 elderly patients (> 80 years old) infected with omicron variant, who were admitted to Department of Infectious Diseases, The First Affiliated Hospital of Naval Medical University (Second Military Medical University) from Apr. to Jun. 2022 and tested positive for SARS-CoV-2 RNA, were included. The level of serum IL-6 was measured by flow cytometry, and the level of serum C reactive protein (CRP) was measured by immunonephelometry. Patients were divided into pneumonia group (16 cases) and non-pneumonia group (6 cases) according to the imaging examination results, and were divided into severe group (severe and critical type, 5 cases) and non-severe group (mild and normal type, 17 cases) according to the condition. Binary logistic regression model and receiver operating characteristic (ROC) curve were used to analyze the correlation between serum IL-6 and CRP levels and the severity of the disease and whether it would progress to pneumonia. Meanwhile, the relationships between underlying diseases and serum IL-6 level were explored. Results: Among the 22 patients, 6 were mild, 11 were normal, 3 were severe, and 2 were critical. The baseline serum IL-6 level in the pneumonia group was significantly higher than that in the non-pneumonia group ([20.16+or-12.36] pg/mL vs [5.42+or-1.57] pg/mL, P=0.009), and there was no significant difference in baseline serum CRP level between the 2 groups (P > 0.05). There were no significant differences in baseline serum IL-6 or CRP levels between the severe group and the non-severe group (both P > 0.05). Logistic regression analysis showed that the baseline serum IL-6 and CRP might be related to pneumonia after infection with omicron variant (odds ratio [OR]=2.407, 95% confidence interval [CI] 0.915-6.328;OR=1.030, 95% CI 0.952-1.114). ROC curve analysis showed that the area under curve values of serum IL-6 and CRP in predicting the progression to pneumonia were 0.969 (95% CI 0.900-1.000) and 0.656 (95% CI 0.380-0.932), respectively, with statistical significance (Z=2.154, P=0.030). There were no significant differences in the baseline serum IL-6 level or proportions of severe patients or pneumonia patients among patients with or without hypertension, diabetes mellitus, coronary heart disease, chronic kidney disease or chronic obstructive pulmonary disease (all P > 0.05). The baseline serum IL-6 levels of the omicron variant infected elderly patients with 1, 2, and 3 or more underlying diseases were 12.50 (9.15, 21.75), 23.55 (9.63, 50.10), and 10.90 (5.20, 18.88) pg/mL, respectively, with no statistical significance (P > 0.05). Conclusion: For omicron variant infected patients, serum IL-6 level is significantly increased in patients with pneumonia manifestations and is correlated with disease progression. Serum IL-6 level is of great guiding significance to judge disease progression and evaluate efficacy and prognosis of elderly coronavirus disease 2019 patients.
ABSTRACT
Objective: To summarize and analyze the epidemiological and clinical characteristics of COVID-19 Omicron variant cases in makeshift hospital, and the influence of age, sex and vaccination status on the disease duration, so as to provide reference for the prevention and control of the COVID-19 epidemic. Methods: The epidemiological and clinical characteristics of COVID-19 cases admitted to makeshift hospital of National Convention and Exhibition Center (Shanghai) from April 9 to May 31, 2022 were retrospectively described and analyzed, and further cohort analysis was conducted to determine the influence of age, sex and vaccination status on the disease duration of COVID-19 cases in the author's branch hospital. Results: Among the 174 466 COVID-19 cases in makeshift hospital, most of them were male, accounting for 59.38%. The infected cases were mainly young and middle-aged people aged 18-59 years old, accounting for 83.50%, followed by 12.30% of the elderly group over 60 years old;the average hospital stay was 7.40 days;the proportion of patients with fever was less than 27.79%;15.37% (26 817/174 466) of the patients complicated with underlying diseases, and the top three were hypertension, diabetes and coronary heart disease. The proportion of people who received COVID-19 vaccine accounted for 79.56% (13 799/17 956), of which the highest proportion of three doses was 44.09%. The disease duration of 17 956 COVID-19 cases in the author's branch of makeshift hospital was 10.18 (7.34, 13.05) days. The disease duration in the elderly group was the longest with 11.34 (8.35, 14.37) days, followed by 11.17 (9.07, 14.33) days in the preschool group, 10.37 (8.14, 13.34) days in the middle-aged group, 10.07 (7.37, 12.37) days in the school-age group, and 9.34 (7.05, 12.16) days in the young group. There was significant difference in the overall distribution of disease duration among the five groups (H=550.479 P < 0.01). The disease duration in each age group basically showed a V-shaped distribution. The disease duration was 10.27 (7.34, 12.57) days in males and 10.10 (7.25, 13.09) days in females, and there was no significant difference (Z=-1.505 P > 0.05). The disease duration of vaccinated patients was 10.24 (7.35, 13.05) days, and that of unvaccinated patients was 9.47 (7.09, 12.47) days. There was significant difference between the two groups (Z=-4.338 P < 0.01). Conclusions: COVID-19 Omicron variant cases have a high proportion of males, mainly young and middle-aged, and the proportion of fever patients is less than 30%. The disease duration is significantly lower than that of the original strain in Wuhan, and shows "V" distribution with each age group. Sex had no effect on the disease duration. COVID-19 vaccination did not have a clinical effect on the disease duration.
ABSTRACT
Objective: To analyze the nucleic acid shedding time of Omicron variant of novel coronavirus in the elderly patients with non-severe infection, and to explore the related factors affecting the nucleic acid shedding time. Methods: A total of 104 elderly patients with non-severe COVID-19 were divided into early negative group (<10 days) and late negative group ( 10 d) by the nucleic acid shedding time. The population information, vaccination, previous diseases, blood biochemical and inflammatory indicators, nucleic acid ORFIab gene and N gene Ct values were collected and compared between the two groups. The Spearman rank correlation and multiple linear regression were conducted to explore the influencing factors of the nucleic acid shedding time. Results: The mean time of nucleic acid shedding of Omicron variant in the early negative group was 7.26: 1.54 d, compared with 12.96: 2.44 d in the late negative group. There were significant differences in age, the ratio of chronic heart failure, chronic pulmonary disease and booster vaccination for COVID-19 and the first nucleic acid Ct value between the two groups (P < 0.05). Spearman correlation analysis showed that the nucleic acid shedding time of Omicron was positively correlated with age, chronic heart failure and serum level of procalcitonin, but negatively correlated with the vaccination booster and the first tested nucleic acid Ct value. Multiple linear regression analysis showed that age, vaccination booster and the first tested nucleic acid Ct value were the independent influencing factors of the nucleic acid shedding time. Conclusions: Age, vaccination booster for COVID-19 and the first tested nucleic acid Ct value were the independent influencing factors of nucleic acid shedding in [the elderly non-severe patients infected by SARS-CoV-2 Omicron. Vaccination booster for COVID-19 in the elderly vulnerable groups can shorten the time of nucleic acid shedding.
ABSTRACT

ABSTRACT
Background and Objective: Coronavirus (COVID-19) is a life-threatening factor worldwide. Identifying the characteristics of the affected population helps to identify risk factors and determine more effective treatment goals. Therefore, the aim of this study was to investigate the demographic characteristics and clinical symptoms of COVID-19 patients hospitalized in West Mazandaran hospitals. Methods: This cross-sectional descriptive study was conducted on 758 patients admitted to the COVID care unit using the census method. The research population was all COVID-19 patients hospitalized in the internal wards, intensive care unit, and ward 550 (for COVID-19 patients) of hospitals from February 13 to May 20, 2021. Data were collected from the care monitoring center and using a demographic questionnaire. Data were analyzed using descriptive and inferential statistical tests through SPSS 22. Findings: Totally, 52.1% and 47.9% of COVID-19 patients were men and women, respectively. The mean and standard deviation of patients' age were 59.77 ..18.22 years. The most common clinical signs were fever (53.7%) and cough (46.3%). There was a statistically significant relationship between contracting COVID-19 and presence of immune-mediated diseases associated with cancer (p=0.0001), diabetes (p=0.008), immune system diseases (p=0.001), heart disease (p=0.0001) and hypertension (p=0.0001) in the studied patients based on treatment outcome (discharge and death). Conclusion: Old age and underlying diseases put people at higher risk for COVID-19. It is recommended that these people should be given more attention.
ABSTRACT
Background: Most common cardio vascular disease events after COVID-19 were hypertension, pulmonary embolism, acute coronary syndrome, myocarditis, stress-Cardiomyopathy, arrhythmias, carcinogenic shock, and cardiac arrest. Aim: To evaluate cardio vascular disease events in patients recovered from COVID-19 in central Indian population Methods: This retrospective observational study was carried out in the department of medicine in a tertiary care hospital, central India. Asses all the participants for post covid cardio vascular events, detailed history, clinical examination and all necessary investigation was done Results: in our study Post COVID 19 cardio vascular events was occur in 17.6%. Majority of the patient was male (69.3%), most common age group were 51-60 years. Higher incidence of cardio vascular disease was reported in obese person. Common cardio vascular diseases found after COVID 19 infection were, hypertension (35.3%), pulmonary embolism (23.5%), Myocarditis (20.6%), myocardial infection (11.8%) and Arrhythmias were in 8.8% cases. Conclusion: Overall observations indicate an increased incidence of hypertension and CVDs post recovery from COVID-19. A dual therapy of ARBs was the preferred choice for management of hypertension. Regular follow-up and close monitoring of symptoms to prevent further CV complications in COVID-19 recovered patients is recommended.
ABSTRACT
Background: There has been a tremendous increase in number of cases of rhino-orbitocerebral involvement with mucor in the COVID era, as reported from India. It is well established that management of ROCM involves early clinical and radiological diagnosis, reversal of underlying risk factors, prompt antifungal therapy and surgical debridement when indicated. Materials &Methods: Multiplanar MR imaging and CT scan were performed for brain, orbit and paranasal sinuses. All the cases were assessed for involvement of the paranasal sinuses, nasal cavities, orbits and brain. Results: 25 cases with ROCM were identified over 8 months. The mean age of the cases was 56.1 years. 18 of the 25 cases had a positive RT-PCR test result at the time of diagnosis with ROCM. 20 cases had poorly controlled diabetes mellitus, 2 had a hematological malignancy, 2 had chronic kidney disease and 1 had ischemic heart disease. There was involvement of the paranasal sinuses, nasal cavities, orbits and brain inclusing necrosis in most of the cases. The number of cases identified during the interval is much higher than the numbers presenting in the prior 2 years during equivalent intervals than those reported in the literature in different settings in the pre-pandemic era. Conclusions: Rhino-orbito mucormycosis can have aggressive necrosis of the involved paranasal sinuses and orbits with or without cerebral extension. Hence, the correct diagnosis is imperative as prompt antifungal drugs and surgical debridement can significantly reduce mortality and morbidity.
ABSTRACT
Objective: This report describes emergency department (ED) visits made by adults with selected chronic conditions associated with severe COVID-19 illness. Methods-Estimates in this report are based on data collected in the 2017-2019 National Hospital Ambulatory Medical Care Survey. Sample data were weighted to produce annual national estimates. Patient characteristics, including age, sex, expected source of payment, medication prescriptions, and hospital admission status, are presented by number of chronic conditions. Selected chronic conditions associated with severe COVID-19 illness include Alzheimer disease or dementia, asthma, cancer, cerebrovascular disease, chronic kidney disease, chronic obstructive pulmonary disease, depression, diabetes, heart disease, HIV, hypertension, obesity, pulmonary embolism, and substance use disorders. Results-For 2017-2019, 59.5% of ED visits made by adults were among those with one or more chronic conditions. The percentage of ED visits made by adults with three or more chronic conditions was highest among those aged 45-64. Medicare was the most frequently observed expected source of payment among adults with three or more chronic conditions. The percentage of ED visits that resulted in a hospital admission increased with the number of chronic conditions. Overall, hypertension was the most frequently observed chronic condition (33.8% of ED visits by adults) and hypertension and diabetes was the most frequently observed dyad, or pair (33.2% of ED visits by adults with at least two chronic conditions). Conclusion-Patients with at least one chronic condition made up 59.5% of adult ED visits. These data provide national estimates of ED visits by the number and type of chronic conditions in the adult population pre-COVID-19. Given that the presence of chronic conditions increases the risk of hospital admission among patients with COVID-19, these data may represent a useful baseline to quantify prevalence and association of chronic conditions associated with COVID-19 with hospitalization experience and outcomes.
ABSTRACT
Objective: To retrospectively analyze the clinical characteristics of 95 patients with severe coronavirus disease 2019 (COVID-19) admitted to Hankou Hospital of Wuhan, and provide evidence for clinical diagnosis and treatment of severe cases. Methods: From January to March 2020, 95 patients with severe COVID-19 were admitted to a designated Hankou Hospital of Wuhan. The clinical manifestations, laboratory examinations, chest CT, respiratory support, drug treatment, and outcomes were collected and analyzed. Results: Among the 95 patients, there were 76(80.0%) severe cases (severe group) and 19 (20.0%) critically ill cases (critically ill group);the average ages of the two groups were (56.9 .. 14.0) and (66.2 .. 14.1) years old, respectively. The main symptoms included fever [85 (89.5%)], cough [73 (76.8%)] dyspnea [57 (60.0%)], sputum expectoration [32 (33.7%)], diarrhea [20 (21.1%)], etc. The initial symptom was fever [64 (67.4%)], followed by cough [17 (17.9%)]. The main comorbidities were hypertension [29 (30.5%)], diabetes [18 (18.9%), coronary heart disease [12 (12.6%)], etc. Liver injury was the most frequently seen complication which occurred in 35 patients (36.8%), while myocardial damage in 20 patients (21.1%), heart failure in 10 patients (10.5%), and renal damage in 8 patients (8.4%). The level of urea nitrogen [7.5 (3.1-36.6) mmol/L], creatinine [88.0 (46.0-681.0) mol/L], aspartate aminotransferase (AST) [49.0 (8.0-2 290.0) U/L], total bilirubin [12.4 (6.8-112.4) mol/L], white blood cells [8.7 (2.7-16.3) .. 109], neutrophil count [7.9 (1.0-14.6) .. 109/L], high-sensitivity C-reactive protein (hsCRP) [35.6 (0.1-37.9) mg/L] and procalcitonin (PCT) [0.3 (0.1-9.6) ng/mL] in the critically ill group were higher than the severe group [4.5 (1.5-14.6) mmol/L, 70.0 (34.0-149.0) mol/L, 30.5 (10.0-184.0) U/L, 7.8 (1.4-24.5) mol/L, 4.5 (1.7- 10.7) .. 109/L 3.1 (0.6-9.1) .. 109/L, 31.8 (0.1- 40.4) mg/L, 0.1 (0.0- 1.2) ng/mL], and the difference were statistically significant (P all < 0.05);the albumin level reflecting nutritional status [30.2 (24.6-36.4) g/L] was lower than the severe group [35.2(23.5-44.5)g/L], and the difference was statistically significant (P < 0.001). Chest computed tomographic scans showed bilateral ground glass opacity or patchy shadows in the lungs of all patients. A total of 77 patients (82.1%) were discharged, and 13 patients (13.7%) died;of which, the mortality of the critically ill group was 68.4% (13 out of 19). Conclusions: The majority of patients with severe COVID- 19 were elderly. The main clinical manifestations were fever, cough, and dyspnea. Most patients had underlying diseases such as hypertension, diabetes and coronary heart disease. The occurrence of organ dysfunctions such as liver injury, cardiac damage, heart failure and kidney injury might be an important cause of death. The mortality of severe patients with COVID-19 was high, and treatment was even tough.
ABSTRACT
The COVID-19 pandemic due to SARS-CoV-2 has proven to be a tremendous challenge to the medical community. The greatest challenge since the turn of the century. The authors summarized the main cardiovascular (CV) complications and mechanisms of COVID-19 and its vaccines. COVID-19 has lung tropism, but it has been reported to affect the CV system as well. The presence of comorbidities such as hypertension, CV disease, diabetes, and chronic obstructive pulmonary disease increased the risk of developing serious complications and in turn mortality significantly. The common CV complications include cardiac arrhythmia, myocardial infarction, myocarditis, and cardiac failure, which occurred in around 20% of all COVID-19 patients. The present difficulty in the diagnosis of CV complications were that COVID-19 symptoms often mimic CV events. Furthermore, the rapid diagnosis and management of serious CV events are sometimes overlooked due to COVID-19. Access to medical treatments were sometimes restricted due to the limited healthcare resources during the pandemic. The advent of various covid vaccines have reduced the number of these complications. However, CV events following mRNA vaccines or adenoviral vector vaccines are recognized as well as myocarditis and vaccine-induced immune thrombotic thrombocytopenia. With increasing experience in managing covid patients with CV complications, physicians are becoming better equipped in preventing, detecting, and treating these complications.
