ABSTRACT

BACKGROUND: After emerging in China, the novel coronavirus disease 2019 (COVID-19) quickly spread to all parts of the country and became a global public health emergency. The Chinese government immediately took a series of protective and quarantine measures to prevent the spread of the virus, and these measures may have negative effects on behavior and psychological health. This study aimed to examine the associations between factors related to COVID-19 measures and mental health symptoms among Chinese college students in different pandemic areas. METHODS: An online survey was administered to 14,789 college students from February 4 to 12, 2020. After excluding the participants who did not complete the questionnaire, the quality of the questionnaire was checked. Finally, the sample included 11,787 college students from 16 cities and 21 universities in China. The areas included the city of Wuhan (Area 1), the neighboring province of Hubei (Area 2), first-tier cities (Beijing, Shanghai, and Guangzhou [Area 3]), and other provinces (Area 4). RESULTS: The average age of the participants was 20.51 ± 1.88 years. One-third of the participants were men. In total, 25.9 and 17.8% reported depression and anxiety, respectively. We also explored COVID-19-related factors, such as infection risk, perceived resistance to COVID-19 (or susceptibility to COVID-19 infection), perceived physical symptoms, family or friends, direct or indirect contact with confirmed cases, and having sought psychological counseling, which were significantly associated with anxiety and depression symptoms. Higher screen time, lower physical activity, higher soda and tea beverages (also called sugar sweetened beverages intake), use of alternative medicines or food supplements (including Chinese herbal medicines and vitamins), and decreased meal frequency were all correlated with higher depression and anxiety symptoms (depression: χ2 = 25.57 and anxiety: χ2 = 39.42). Coping with COVID-19 partially mediated the associations between some related lifestyle behaviors, anxiety, and depression. The conditional process model analysis results supported our hypotheses that lifestyle health behaviors and coping style were both predictors of anxiety and depression symptoms, and their direct and indirect effects were moderated by sex. CONCLUSIONS: Compared with the city of Wuhan, other epidemic areas had a lower risk of mental health problems. Lifestyle health behaviors and coping styles alleviated mental health symptoms. COVID-19-related social stressors were positively associated with mental health symptoms.

ABSTRACT

The coronavirus disease 2019 (COVID-19) pandemic poses a serious threat to human life and health. To establish a method for quantitative detection of detection of the spike glycoprotein of severe acute respiratory syndrome coronavirus'Z (SARS-CoV-Z) in vaccines. Goat anti-SARS-CoV-Z polyclonal antibody and mouse anti -SARS -CoV-Z spike glycoprotein monoclonal antibody were prepared to establish a double antibody sandwich enzymerlinked immunosorbent assay (ELISA) for detection of the spike glycoprotein. The ELISA system was optimized and the linear range, sensitivity, specificity, repeatability and coincidence rate were tested. The linear range was 1-64 U and correlation coefficient (R2) > 0.99. There was no reaction with the nucleocapsid protein, Vero-cell debris or influenza Viruses, etc, indicating the high specificity of our method. The sensitivity was 92.1% and the variations in intra- and inter' assay repeatability were 2.5%-11.7% and 1.3% -14.8%, respectively. The samples showed a coincidence rate Of 96.7% with known background. Our method had high specificity, sensitivity, stability and accuracy, and could be used for determination of spike - glycoprotein antigen content in vaccine.

ABSTRACT

OBJECTIVE: To evaluate the effect of 2019 novel coronavirus inactivated vaccine on the disease severity of patients with Delta variant of coronavirus disease 2019. METHODS: A retrospective analysis was performed on 704 patients with coronavirus disease 2019 infected with Delta variant who were older than 18 years old and admitted in the coronavirus disease 2019 designated hospital of Yangzhou (Subei Hospital New Area Branch) from July 2021 to September 2021. They were divided into severe (severe, critical) group and non-severe (light, ordinary) group according to the clinical characteristics of patients. According to the vaccination status, they were divided into 0-dose group, 1-dose group and 2-dose group. We evaluated the effects of vaccination on the severity of the disease and the production of antibodies, and analyzed the influencing factors leading to the severe group of coronavirus disease 2019. RESULTS: The proportion of severe group in the 2-dose vaccinated group was significantly lower than that in the 1-dose vaccinated group and 0-dose vaccinated group [3.02% (7/232) vs. 9.48% (22/232), 15.83% (38/240), P < 0.05]. The time from onset to admission (day: 1.97±1.66 vs. 2.66±2.70), age (years: 45.3±12.2 vs. 63.6±17.0), direct bilirubin [DBil (µmol/L): 3.70±1.83 vs. 5.30±5.13], lactate dehydrogenase [LDH (U/L): 240.69±74.29 vs. 256.30±85.18], creatinine [SCr (µmol/L): 63.38±19.86 vs. 70.23±25.43], interleukin-6 [IL-6 (ng/L): 7.32 (1.54, 17.40) vs. 18.38 (8.83, 33.43)], creatine kinase [CK (U/L): 66.00 (43.00, 99.75) vs. 78.00 (54.50, 144.00)] and D-dimer [mg/L: 0.30 (0.08, 0.49) vs. 0.41 (0.23, 0.69)] of patients in the 2-dose group were significantly lower than those in the 0-dose group (all P < 0.05), while platelet [PLT (×109/L): 176.69±60.25 vs. 149.25±59.07], white blood cell count [WBC (×109/L): 5.43±1.77 vs. 5.03±1.88] and lymphocyte [LYM (×109/L): 1.34±0.88 vs. 1.17±0.50] were significantly higher than those in the 0-dose group (all P < 0.05). The titer of immunoglobulin G (IgG) in the 2-dose group was significantly higher than those in the 1-dose group and 0-dose group on the 10th day after admission [U/L: 130.94 (92.23, 326.31), 113.18 (17.62, 136.20), 117.85 (33.52, 156.73), both P < 0.05], and higher than 0-dose group on the 16th day [U/L: 156.12 (120.32, 167.76) vs. 126.52 (61.34, 149.57), P < 0.05]. The proportion of complete 2-dose vaccination [10.45% (7/67) vs. 35.32% (225/637)], LYM (×109/L: 1.09±0.32 vs. 1.25±0.56) and PLT (×109/L: 138.55±68.03 vs. 166.93±59.70) in the severe group were significantly lower than those in the non-severe group (P < 0.05), while the time from onset to admission (day: 3.01±2.99 vs. 2.25±2.09), the length of hospital stay (day: 28±18 vs. 16±6), male proportion [77.61% (52/67) vs. 34.54% (220/637)], age (years: 69.13±12.63 vs. 52.28±16.53), DBil [µmol/L: 4.20 (3.18, 6.65) vs. 3.60 (2.80, 4.90], LDH (U/L: 310.61±98.33 vs. 238.19±72.14), SCr (µmol/L: 85.67±38.25 vs. 65.98±18.57), C-reactive protein [CRP (µmol/L): 28.12 (11.32, 42.23) vs. 8.49 (2.61, 17.58)], IL-6 [ng/L: 38.38 (24.67, 81.50) vs. 11.40 (4.60, 22.07)], CK [U/L: 140.00 (66.00, 274.00) vs. 72.80 (53.00, 11.00)] and the D-dimer [mg/L: 0.46 (0.29, 0.67) vs. 0.35 (0.19, 0.57)] in the severe group were significantly higher than those in the non-severe group (all P < 0.05). Multivariate regression analysis showed that the odds ratio (OR) of severe group was 0.430 (P = 0.010) in the 1-dose group and the 2-dose group compared with the 0-dose group. However, the risk of severe group was 0.381-fold in the 2-dose group compared with the 0-dose group [OR = 0.381, 95% confidence interval (95%CI) was 0.121-1.199] which was not statistically significant, when the age was included in the regression analysis (P > 0.05). PLT (OR = 0.992, 95%CI was 0.986-0.998) were protective factors, but older than 60 years old (OR = 3.681, 95%CI was 1.637-8.278), CK (OR = 1.001, 95%CI was 1.000-1.001), IL-6 (OR = 1.006, 95%CI was 1.002-1.010), SCr (OR = 1.020, 95%CI was 1.007-1.033) were risk factors for severe group (all P < 0.05). CONCLUSIONS: Compared with the 0-dose vaccinated patients, the coronavirus disease 2019 patients infected with delta variant and fully vaccinated with 2-dose 2019 novel coronavirus inactivated vaccine had lower level of IL-6, SCr, CK and D-dimer, and higher PLT, LYM and IgG titer, who were not easy to develop into the severe condition.

ABSTRACT

Background: Autism spectrum disorders (ASD) are heterogeneous neurodevelopmental conditions that affect people worldwide. Early diagnosis and clinical support help achieve good outcomes. However, medical system structure and restricted resource availability create challenges that increase the risk of poor outcomes. Understanding the research progress of childhood ASD in recent years, based on clinical literature reports, can give relevant researchers and rehabilitation therapists more resonable research guides. Objective: This bibliometric study aimed to summarize themes and trends in research on childhood ASD and to suggest directions for future enquiry. Methods: Citations were downloaded from the Web of Science Core Collection database on childhood ASD published from 1 January 2012, to 31 December 2021. The retrieved information was analyzed using CiteSpace.5.8. R3, and VOS viewer. Results: A total of 7,611 papers were published across 103 areas. The United States was the leading source of publications. The clusters that have continued into 2020 include coronavirus disease 2019, gut microbiota, and physical activity, which represent key research topics. Keywords with frequency spikes during 2018-2021 were "disabilities monitoring network," "United States," and "caregiver." Conclusions: The Autism and Developmental Disabilities Monitoring Network in the United States can be used as a reference for relevant workers worldwide. An intelligent medical assistant system is being developed. Further studies are required to elucidate challenges associated with caring for a child with ASD.

ABSTRACT

Background: The COVID-19 pandemic has changed the social environment of most individuals around the world and has profoundly impacted people's lives, ontological security, and behavior. Among them, the patients are one of the groups most influenced by the pandemic. Objective: The present research aimed to study the relationship of COVID-19 pandemic-induced disruption to patients' daily lives, ontological security, and patients' responses to prevent the spread of COVID-19, and explore the role of ontological security. Methods: This article was based on an online structured questionnaire study conducted among hospitalized patients in Taizhou Hospital of Zhejiang Province, Taizhou, China, from 8 July to 11 August 2021. We analyzed the data using the multivariate regression model and mediation analysis method. Results: The results showed that the higher the pandemic-induced disruption to inpatients' lives, the better behavior would be taken by hospitalized patients to prevent the spread of COVID-19, and the perceived scarcity of ontological security played a mediating role in this process. Higher pandemic-induced disruption to patients' lives increased the ontological insecurity which further, in turn, reduced patients' good practice toward measures to prevent the novel coronavirus. Conclusion: These findings provided direct evidence for the relationship between pandemic-induced disruption, scarcity of ontological security, and patients' prevention behavior. It suggested that there was a need to emphasize patients' ontological security. Overall, these findings suggested that it is important to emphasize the mental health among patients during the COVID-19 pandemic, and implement strategies to offer psychological support when needed.

ABSTRACT

Data regarding the epidemiologic characteristics and clinical features of pediatric hematologic patients are limited in this corona virus disease 2019 (COVID-19) crisis. We investigated the status of 113 pediatric hematologic patients in Wuhan union hospital during the COVID-19 pandemic from January 23 to March 10, 2020. All the patients had routine blood and biochemical examination, as well as chest computed tomography scans, and the nucleic acid, immunoglobulin G-immunoglobulin M combined antibodies tests for SARS-CoV-2. After admission, all patients were single-room isolated for 5 to 7 days. The results showed that only 1 (0.88%) child with leukemia was confirmed to have SARS-CoV-2 infection and 15 (13.2%) children were considered as suspected cases. Comparing to the nonsuspected patients, the suspected cases had lower white blood cell count, hemoglobin level, neutrophil count, serum calcium ion level and serum albumin concentration, as well as higher levels of C-reactive protein. All the suspected cases were ruled out of SARS-CoV-2 infection by twice negative tests for the virus. Therefore, the incidence of SARS-CoV-2 infection in hematologic malignancy children was low during the COVID-19 pandemic in China. COVID-19 got early detected and the virus spread out in the ward was effectively blocked by increasing test frequency and using single-room isolation for 5 to 7 days after admission.

ABSTRACT

BACKGROUND: The 2019 novel coronavirus disease (COVID-19) emerges in China, which spreads rapidly and becomes a public health emergency of international concern. Chinese government has promptly taken quarantine measures to block the transmission of the COVID-19, which may cause deleterious consequences on everyone's behaviors and psychological health. Few studies have examined the associations between behavioral and mental health in different endemic areas. This study aimed to describe screen time (ST), physical activity (PA), and depressive symptoms, as well as their associations among Chinese college students according to different epidemic areas. METHODS: The study design is cross-sectional using online survey, from 4 to 12 February 2020, 14,789 college students accomplished this online study, participants who did not complete the questionnaire were excluded, and finally this study included 11,787 college students from China. RESULTS: The average age of participants was 20.51 ± 1.88 years. 57.1% of the college students were male. In total, 25.9% of college students reported depression symptoms. ST > 4 h/day was positively correlated with depressive symptoms (ß = 0.48, 95%CI 0.37-0.59). COVID-19ST > 1 h/day was positively correlated with depressive symptoms (ß = 0.54, 95%CI 0.43-0.65), compared with COVID-19ST ≤ 0.5 h/day. Compared with PA ≥ 3 day/week, PA < 3 day/week was positively associated with depression symptoms (ß = 0.01, 95%CI 0.008-0.012). Compared with low ST and high PA, there was an interaction association between high ST and low PA on depression (ß = 0.31, 95%CI 0.26-0.36). Compared with low COVID-19ST and high PA, there was an interaction association between high COVID-19ST and low PA on depression (ß = 0.37, 95%CI 0.32-0.43). There were also current residence areas differences. CONCLUSIONS: Our findings identified that high ST or low PA was positively associated with depressive symptoms independently, and there was also an interactive effect between ST and PA on depressive symptoms.

ABSTRACT

Diseases caused by pathogenic bacteria in animals (e.g., bacterial pneumonia, meningitis and sepsis) and plants (e.g., bacterial wilt, angular spot and canker) lead to high prevalence and mortality, and decomposition of plant leaves, respectively. Melatonin, an endogenous molecule, is highly pleiotropic, and accumulating evidence supports the notion that melatonin's actions in bacterial infection deserve particular attention. Here, we summarize the antibacterial effects of melatonin in vitro, in animals as well as plants, and discuss the potential mechanisms. Melatonin exerts antibacterial activities not only on classic gram-negative and -positive bacteria, but also on members of other bacterial groups, such as Mycobacterium tuberculosis. Protective actions against bacterial infections can occur at different levels. Direct actions of melatonin may occur only at very high concentrations, which is at the borderline of practical applicability. However, various indirect functions comprise activation of hosts' defense mechanisms or, in sepsis, attenuation of bacterially induced inflammation. In plants, its antibacterial functions involve the mitogen-activated protein kinase (MAPK) pathway; in animals, protection by melatonin against bacterially induced damage is associated with inhibition or activation of various signaling pathways, including key regulators such as NF-κB, STAT-1, Nrf2, NLRP3 inflammasome, MAPK and TLR-2/4. Moreover, melatonin can reduce formation of reactive oxygen and nitrogen species (ROS, RNS), promote detoxification and protect mitochondrial damage. Altogether, we propose that melatonin could be an effective approach against various pathogenic bacterial infections.

ABSTRACT

Objective: To identify the effectiveness of a personnel protection strategy in protection of healthcare workers from SARS-CoV-2 infection. Design: During the COVID-19 pandemic, 943 healthcare staff sent from Guangzhou to Wuhan to care for patients with suspected/confirmed COVID-19 received infection precaution training before their mission and were equipped with Level 2/3 personal protective equipment (PPE), in accordance with guidelines from the National Health Commission of China. We conducted a serological survey on the cumulative attack rate of SARS-CoV-2 among the healthcare workers sent to Wuhan and compared the seropositive rate to that in local healthcare workers from Wuhan and Jingzhou. Results: Serial tests for SARS-CoV-2 RNA and tests for SARS-CoV-2 immunoglobulin M and G after the 6-8 week mission revealed a zero cumulative attack rate. Among the local healthcare workers in Wuhan and Jingzhou of Hubei Province, 2.5% (113 out of 4495) and 0.32% (10 out of 3091) had RT-PCR confirmed COVID-19, respectively. The seropositivity for SARS-CoV-2 antibodies (IgG, IgM, or both IgG/IgM positive) was 3.4% (53 out of 1571) in local healthcare workers from Wuhan with Level 2/3 PPE working in isolation areas and 5.4% (126 out of 2336) in healthcare staff with Level 1 PPE working in non-isolation medical areas, respectively. Conclusions and relevance: Our study confirmed that adequate training/PPE can protect medical personnel against SARS-CoV-2.

ABSTRACT

OBJECTIVE/BACKGROUND: School closure and home quarantine has been implemented worldwide during the coronavirus disease 2019 (COVID-19) outbreak. The study aims to assess the associations of circadian rhythm abnormalities (CRA) during the COVID-19 outbreak with mental health in Chinese undergraduates. METHODS: A nationwide cross-sectional university-based survey was conducted from 4th February to 12th, 2020. Based on different geographical locations and purposive sampling approach, 19 universities from 16 provinces or municipalities in the mainland of China were selected. A total of 14,789 participants were recruited by using multistage stratified random sampling. The data of CRA were collected by self-reported questionnaires consist of four items involved rest-activity cycle, diet rhythm, wake up rhythm and sleep rhythm. The Patient Health Questionnaire and the Generalized Anxiety Disorder were applied to evaluate the symptoms of depression and anxiety. Chi-square test and ordinal logistic regression models were used to describe the distributions and associations of CRA and mental health. RESULTS: A total of 11,787 students [female: 6731(57.1%)] aged 15-26 years old (M = 20.45, SD = 1.76) were analyzed (response rate: 79.7%). The results showed the percentage of CRA were 17.5-28.7%. The prevalence of depression and anxiety were significantly higher in students with single CRA. Students who reported the coexistence of four CRA were more likely to be with the symptoms of depression (OR: 4.43, 95% CI: 3.91-5.03) and anxiety (OR: 3.11, 95% CI: 2.70-3.60). Dose-response relationships were found between multiple CRA and mental problems. CONCLUSION: Circadian rhythm abnormalities are positively associated with mental health among university studies. Mental health care is needed for college students during the COVID-19 epidemic period.

ABSTRACT

Background: Accumulating evidence has revealed that coronavirus disease 2019 (COVID-19) patients may be complicated with myocardial injury during hospitalization. However, data regarding persistent cardiac involvement in patients who recovered from COVID-19 are limited. Our goal is to further explore the sustained impact of COVID-19 during follow-up, focusing on the cardiac involvement in the recovered patients. Methods: In this prospective observational follow-up study, we enrolled a total of 40 COVID-19 patients (20 with and 20 without cardiac injury during hospitalization) who were discharged from Zhongnan Hospital of Wuhan University for more than 6 months, and 27 patients (13 with and 14 without cardiac injury during hospitalization) were finally included in the analysis. Clinical information including self-reported symptoms, medications, laboratory findings, Short Form 36-item scores, 6-min walk test, clinical events, electrocardiogram assessment, echocardiography measurement, and cardiac magnetic resonance imaging was collected and analyzed. Results: Among 27 patients finally included, none of patients reported any obvious cardiopulmonary symptoms at the 6-month follow-up. There were no statistically significant differences in terms of the quality of life and exercise capacity between the patients with and without cardiac injury. No significant abnormalities were detected in electrocardiogram manifestations in both groups, except for nonspecific ST-T changes, premature beats, sinus tachycardia/bradycardia, PR interval prolongation, and bundle-branch block. All patients showed normal cardiac structure and function, without any statistical differences between patients with and without cardiac injury by echocardiography. Compared with patients without cardiac injury, patients with cardiac injury exhibited a significantly higher positive proportion in late gadolinium enhancement sequences [7/13 (53.8%) vs. 1/14 (7.1%), p = 0.013], accompanied by the elevation of circulating ST2 level [median (interquartile range) = 16.6 (12.1, 22.5) vs. 12.5 (9.5, 16.7); p = 0.044]. Patients with cardiac injury presented higher levels of aspartate aminotransferase, creatinine, high-sensitivity troponin I, lactate dehydrogenase, and N-terminal pro-B-type natriuretic peptide than those without cardiac injury, although these indexes were within the normal range for all recovered patients at the 6-month follow-up. Among patients with cardiac injury, patients with positive late gadolinium enhancement presented higher cardiac biomarker (high-sensitivity troponin I) and inflammatory factor (high-sensitivity C-reactive protein) on admission than the late gadolinium enhancement-negative subgroup. Conclusions: Our preliminary 6-month follow-up study with a limited number of patients revealed persistent cardiac involvement in 29.6% (8/27) of recovered patients from COVID-19 after discharge. Patients with cardiac injury during hospitalization were more prone to develop cardiac fibrosis during their recovery. Among patients with cardiac injury, those with relatively higher cardiac biomarkers and inflammatory factors on admission appeared more likely to have cardiac involvement in the convalescence phase.

ABSTRACT

BACKGROUND: Coronavirus disease 2019 (COVID-19) is an emerging infectious disease that first manifested in humans in Wuhan, Hubei Province, China, in December 2019, and has subsequently spread worldwide. METHODS: We conducted a retrospective, single-center case series of the seven maintenance hemodialysis (HD) patients infected with COVID-19 at Zhongnan Hospital of Wuhan University from 13 January to 7 April 2020 and a proactive search of potential cases by chest computed tomography (CT) scans. RESULTS: Of 202 HD patients, 7 (3.5%) were diagnosed with COVID-19. Five were diagnosed by reverse transcription polymerase chain reaction (RT-PCR) because of compatible symptoms, while two were diagnosed by RT-PCR as a result of screening 197 HD patients without respiratory symptoms by chest CT. Thirteen of 197 patients had positive chest CT features and, of these, 2 (15%) were confirmed to have COVID-19. In COVID-19 patients, the most common features at admission were fatigue, fever and diarrhea [5/7 (71%) had all these]. Common laboratory features included lymphocytopenia [6/7 (86%)], elevated lactate dehydrogenase [3/4 (75%)], D-dimer [5/6 (83%)], high-sensitivity C-reactive protein [4/4 (100%)] and procalcitonin [5/5 (100%)]. Chest CT showed bilateral patchy shadows or ground-glass opacity in the lungs of all patients. Four of seven (57%) received oxygen therapy, one (14%) received noninvasive and invasive mechanical ventilation, five (71%) received antiviral and antibacterial drugs, three (43%) recieved glucocorticoid therapy and one (14%) received continuous renal replacement therapy. As the last follow-up, four of the seven patients (57%) had been discharged and three patients were dead. CONCLUSIONS: Chest CT may identify COVID-19 patients without clear symptoms, but the specificity is low. The mortality of COVID-19 patients on HD was high.

ABSTRACT

BACKGROUND: Since the COVID-19 outbreak was first reported, considerable attention has been drawn to mental health problems among college students. OBJECTIVE: We aimed to estimate the prevalence of anxiety and depressive symptoms among college students in different geographical areas of China during the early stage of the COVID-19 outbreak. METHODS: A nationwide cross-sectional survey was conducted among Chinese college students of 16 provinces or municipalities from February 4 to 12, 2020. A web-based survey was adopted to collect information from these college students, including demographics, perceived risk of infection, attitudes toward the epidemic and its control, and mental health status. Anxiety symptoms were assessed using the Generalized Anxiety Disorder scale, and depressive symptoms were assessed using the Patient Health Questionnaire. Chi-square test was used to compare the percentage of perceived risk of infection and attitude toward COVID-19 among college students in different geographic locations. Binary logistic models were used to identify associations between geographic locations and mental health problems after controlling for covariates. RESULTS: A total of 11,787 participants were analyzed in this study (response rate: 79.7%). The prevalence of anxiety and depressive symptoms among college students was 17.8% (95% CI 17.1%-18.5%) and 25.9% (95% CI 25.1%-26.7%), respectively. After controlling for covariates, current residence area in Wuhan city was found to have a positive association with anxiety symptoms (odds ratio [OR] 1.37, 95% CI 1.11-1.68) and depressive symptoms (OR 1.32, 95% CI 1.09-1.59). Similarly, college location in Wuhan city was found to have a positive association with anxiety symptoms (OR 1.20, 95% CI 1.07-1.35) and depressive symptoms (OR 1.22, 95% CI 1.10-1.36). History of residence in or travel to Wuhan city in the past month was also positively associated with anxiety symptoms (OR 1.62, 95% CI 1.46-1.80) and depressive symptoms (OR 1.48, 95% CI 1.35-1.63). Furthermore, the perceived risk of COVID-19 was higher among students whose college location and current residence area were in Wuhan city, and it was positively associated with anxiety and depressive symptoms. CONCLUSIONS: During the COVID-19 pandemic, mental health problems among Chinese college students were widespread and geographically diverse. Our study results provide further insight for policymakers to develop targeted intervention strategies.

ABSTRACT

Background: Statins have multiple protective effects on inflammation, immunity and coagulation, and may help alleviate pneumonia. However, there was no report focusing on the association of statin use with in-hospital outcomes of patients with coronavirus disease 2019 (COVID-19). We investigated the association between the use of statins and in-hospital outcomes of patients with COVID-19. Methods: In this retrospective case series, consecutive COVID-19 patients admitted at 2 hospitals in Wuhan, China, from March 12, 2020 to April 14, 2020 were analyzed. A 1:1 matched cohort was created by propensity score-matched analysis. Demographic data, laboratory findings, comorbidities, treatments and in-hospital outcomes were collected and compared between COVID-19 patients taking and not taking statins. Result: A total of 2,147 patients with COVID-19 were enrolled in this study. Of which, 250 patients were on statin therapy. The mortality was 2.4% (6/250) for patients taking statins while 3.7% (70/1,897) for those not taking statins. In the multivariate Cox model, after adjusting for age, gender, admitted hospital, comorbidities, in-hospital medications and blood lipids, the risk was lower for mortality (adjusted HR, 0.428; 95% CI, 0.169-0.907; P = 0.029), acute respiratory distress syndrome (ARDS) (adjusted HR, 0.371; 95% CI, 0.180-0.772; P = 0.008) or intensive care unit (ICU) care (adjusted HR, 0.319; 95% CI, 0.270-0.945; P = 0.032) in the statin group vs. the non-statin group. After propensity score-matched analysis based on 18 potential confounders, a 1:1 matched cohort (206:206) was created. In the matched cohort, the Kaplan-Meier survival curves showed that the use of statins was associated with better survival (P = 0.025). In a Cox regression model, the use of statins was associated with lower risk of mortality (unadjusted HR, 0.254; 95% CI, 0.070-0.926; P = 0.038), development of ARDS (unadjusted HR, 0.240; 95% CI, 0.087-0.657; P = 0.006), and admission of ICU (unadjusted HR, 0.349; 95% CI, 0.150-0.813; P = 0.015). The results remained consistent when being adjusted for age, gender, total cholesterol, triglyceride, low density lipoprotein cholesterol, procalcitonin, and brain natriuretic peptide. The favorable outcomes in statin users remained statistically significant in the first sensitivity analysis with comorbid diabetes being excluded in matching and in the second sensitivity analysis with chronic obstructive pulmonary disease being added in matching. Conclusion: In this retrospective analysis, the use of statins in COVID-19 patients was associated with better clinical outcomes and is recommended to be continued in patients with COVID-19.

ABSTRACT

Objective@#To describe the epidemiological characteristics and clinical manifestations of the 2019 coronavirus disease (COVID-19) in pediatric patients, and to provide data support and decision-making basis for the prevention and control of COVID-19.@*Methods@#Cases of children aged 0-17 years reported by provincial health commissions in Anhui, Shandong, Zhejiang and Henan provinces were collected to analyze their spatial, temporal, and demographic distribution.@*Results@#By 24:00 on February 6, 2020, a total of 107 pediatric patients had been reported in the four provinces, accounting for 3.8% (107/2 808) of the total cases reported in the four provinces during the same period. Anhui, Shandong, Zhejiang and Henan provinces had 25, 25, 28 and 29 cases, respectively. Cases ranged in age from 5 days after birth to 17 years, with a median age of 8 years. Boys accounted for 58.9%. Totally 38 cases had a history of sojourn in Wuhan or Hubei, 63 cases had a history of exposure to confirmed cases, and 6 cases with unknown exposure history. A group of 52 family clustering were found in 107 cases. All cases presented mild symptoms, no serious and no death.@*Conclusion@#Children were also susceptible to the COVID-19. Before February 2, the index pediatric cases were mainly the first generation cases, and after February 3, these pediatric cases were mainly the secondary-generation cases and those who had close contact with confirmed cases. The monitoring of children with secondgeneration cases and close contact with COVID-19 cases were valued.
