ABSTRACT

Objective: To systematically examine the efficacy and safety of antidepressants for the treatment of coronavirus disease 2019 (COVID-19).Methods: A systematic search was performed independently by two researchers based on Chinese Journal Net, WanFang, PsycINFO, Cochrane Library, PubMed, and EMBASE.Results: Seven studies (n = 92,947) including three retrospective studies (n = 91,083), two randomized clinical trials (RCTs, n = 1649), two prospective cohort study (n = 215) involving (n = 92,947) patients with COVID-19 were examined. For RCTs, fluvoxamine outperformed placebo in reducing clinical deterioration and hospitalisation for COVID-19 patients. For retrospective studies, antidepressants (2 studies) and fluoxetine (1 study) possibly reduced the risk of mortality in patients with COVID-19. Results from two remaining studies supported the superiority of fluvoxamine in reducing risk of mortality in COVID-19 patients. The two RCTs that examined the safety of fluvoxamine for COVID-19 patients found inconsistent results but no significant group differences in the dropout rate.Conclusion: This systematic review found emerging evidence for fluvoxamine in reducing the risk of mortality and hospitalisation in COVID-19 patients, but inconsistent evidence for the safety of fluvoxamine in COVID-19 patients. More studies are needed to determine the efficacy and safety of antidepressants for the treatment of COVID-19.

ABSTRACT

The outbreak of the novel coronavirus disease 2019 (COVID-19) has posed a great impact on people's mental health, especially for undergraduate students. This study aimed to compare the mental health conditions and academic burnout between medical and non-medical undergraduates in China when the COVID-19 pandemic is mitigating. A cross-sectional online survey was conducted among 4,972 undergraduates between October 2020 and April 2021, when the pandemic was basically under control. The survey included basic demographics information and standardized scales to evaluate depression, anxiety, perceived stress, daytime sleepiness, alcohol abuse/dependence, quality of life, fatigue, and academic burnout. Compared with medical undergraduates, non-medical undergraduates had higher rates of moderate to severe depression symptoms (29.1% vs. 17.9%, P < 0.001), moderate to severe anxiety symptoms (19.7% vs. 8.9%, P < 0.001), alcohol abuse/dependence (16.3% vs.10.3%, P < 0.001), excessive daytime sleepiness (47.4% vs. 43.4%, P = 0.018), high perceived stress (34.7% vs. 22.2%, P < 0.001), high level of fatigue (51.8% vs. 42.2%, P < 0.001), low QOL (35.8% vs. 21.4%, P < 0.001), and higher academic burnout score (59.4 vs. 57.5, P < 0.001). Being non-medical undergraduates, depression, alcohol abuse/dependence, excessive daytime sleepiness, and high perceived stress were positively associated with academic burnout, while high QOL was negatively associated with the burnout (all P < 0.001). Excessive daytime sleepiness was the strongest predictor for academic burnout.

ABSTRACT

Background: Intravenous thrombolysis is still underutilized in patients with acute ischemic stroke (AIS) in China. A promising strategy for addressing this issue, especially in situations, such as the global pandemic of coronavirus disease 2019 (COVID-19), is the telestroke mode, which remains to be widely implemented in China. The present study aimed to assess the effects of telemedicine for patients with stroke in Western China, as well as the impact of the pandemic on telestroke services in 1 year after the COVID-19 outbreak. Methods: In this 2-year multicenter observational study, we retrospectively collected data from 10 hospitals within the Sichuan Telestroke and Telethrombolysis Network. Demographic and clinical characteristics of patients with IS and those relevant to thrombolysis were compared between the pre-telestroke and post-telestroke phases, and between the periods before and after declaration of the COVID-19 pandemic. Results: A total of 11,449 admissions with a primary diagnosis of IS were recorded during the study period. Prior to telestroke implementation, 6.7% of patients (n = 367) received intravenous thrombolysis, and the proportion increased to 7.4% (n = 443; p = 0.084) in the post-telestroke phase. The thrombolysis rate was 7.4% during the COVID-19 pandemic and in the latter half of the year when the viral spread was better controlled in China. The mean door-to-needle time (DNT) was significantly shorter after implementation of the telestroke network (63.76 ± 13.50 vs. 52.66 ± 25.49 min; p < 0.001). Conclusions: Telemedicine is effective in improving the thrombolysis administration among patients with IS in Western China. Implementation of the telestroke network should be promoted, especially when access to care is affected by public health emergencies, such as the COVID-19 pandemic.

ABSTRACT

To investigate parenting and children’s emotional and lifestyle responses to the COVID-19 epidemic, we conducted an online survey of random, representative sample of residents with children aged 3–17 years in mid-March, 2020 in China. 1655 parents were surveyed with 80.1% response rate. During the epidemic, half (49%) of children had stress symptoms and 10% had emotional problems;children had higher screen time, less exercise and worse sleep than before. Socially disadvantaged children were more vulnerable to the epidemic. Children whose parents communicated about the epidemic more frequently, who had irritable parents and experienced worse parent-child closeness had higher probabilities of emotional problems, stress symptoms and worse lifestyles. Improve parenting skills and communication quality is necessary during the epidemic.

ABSTRACT

Background: Laboratory abnormalities associated with disease severity and mortality in patients with coronavirus disease 2019 (COVID-19) have been reported in many observational studies. However, there are significant heterogeneities in patient characteristics and research methodologies in these studies.ObjectivesWe aimed to provide an updated synthesis of the association between laboratory abnormalities and COVID-19 prognosis.MethodsWe conducted an electronic search of PubMed, Scopus, Ovid, Willey, Web of Science, and the China National Knowledge Infrastructure (CNKI) for studies reporting hematological, coagulation, inflammatory, and immunological results during hospital admission of COVID-19 patients with different severities and outcomes.ResultsA total of 64 studies were included in the current meta-analysis, with 8 hematological, 3 coagulation, 5 inflammatory, and 23 immunological variables reported. Of them, white blood cell (WBC) and neutrophil counts (Neu), D-dimer level, procalcitonin (PCT), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), ferretin, serum amyloid A (SAA), interleukins (ILs)–2R, IL-6, and IL-10 were significantly increased in severely ill patients and non-survivors. Meanwhile, non-severely ill patients and survivors presented significantly higher counts of eosinophils, lymphocytes, and CD4 + and CD8 + T cells. A majority of included variables presented with significant heterogeneity, some of which resulted from differing disease severities and ages of included patients.ConclusionsThe current meta-analysis provides a comprehensive and updated synthesis of the association between admission laboratory abnormalities with severity and mortality of COVID-19. Our results highlight that increases in the levels of PCT, ESR, CRP, ferretin, SAA, IL-2R, IL-6, and IL-10 were associated with disease deterioration, whereas elevated eosinophils, lymphocytes, and T-cell subsets might serve as indicators of favorable outcomes.

ABSTRACT

Background: The COVID-19 pandemic posed tremendous threats to the world. Elderly patients were among the high-risk population, and apt to experience worse outcomes. Methods: : Elderly patients (age ≥60 years old) were enrolled from January 28 to February 29, 2020, in Tongji Hospital, one of designated COVID-19 medical centers in Wuhan, China. A retrospective study was performed to describe clinical characteristics and outcomes of elderly COVID-19 patients. COX regression was used to analyze predictors for 28-day mortality. Linear regression models were constructed to analyze factors associated with length of hospital stay (LOS). Result: A total of 186 elderly patients (aged 70.4 ± 7.1 years, 95 males (51.6%)) were enrolled, 120 patients (64.5%) were severe or critical type, and mortality rate was 16.1%. Patients in non-survival group had a higher smoking rate, more symptoms of dyspnea, lab results indicative of poorer health. Age (HR 1.128, 95% CI 1.066-1.194), lymphocyte count (HR 0.261, 95% CI 0.073-0.930), LDH (HR 1.003, 95% CI 1.002-1.005), procalcitonin (HR 1.061, 95% CI 1.002-1.125), and qSOFA (HR 3.162, 95% CI 1.646-6.072) were independently associated with 28-day mortality. CURB-65 plus LDH on admission were predictors of mortality by ROC analysis (AUROC=0.891). Among surviving patients, consolidation on CTs, elevated ferritin level and neutrophil count were associated with increased LOS. Conclusion: High incidence of comorbidities and mortality were observed in elderly patients. Decreased lymphocyte, older age, higher qSOFA score, procalcitonin and LDH levels were independent factors associated with mortality, CURB-65 plus LDH could be a predictive model of fatal outcome. Consolidation on CTs, elevated ferritin and neutrophil level correlated with increased LOS. Further prospective studies should be performed to test our findings and explore potential treatments.

ABSTRACT

Background: The novel coronavirus disease 2019 (Covid-19) has been a worldwide pandemic with more than 300,000 deaths. Corticosteroids have been used in some patients with severe Covid-19 in order to control the systemic inflammation or cytokine storm, however, their effects and safety have not yet been elucidated. Methods Patients with confirmed Covid-19 were retrospectively included from both the epicentre and out of the epicentre. Patients were classified into two groups according to the use of systemic corticosteroids, and the mortality and the rate of virus clearance were compared between the two groups. In addition, independent factors associated with death after corticosteroids treatment were also identified. Results A total of 775 patients were included in our final analysis, of which 238 (30.7%) patients received systemic corticosteroids treatment. Compared with patients without corticosteroids treatment, patients with corticosteroids treatment had significantly higher mortality (19.3% vs. 3.7%, P < 0.001) and lower rate of virus clearance (43.2% vs. 66.7%, P < 0.001) although along with increase of SpO 2 /FiO 2 and blood lymphocytes in patients with severe Covid-19. Corticosteroids treatment was associated with longer hospital length of stays and delayed virus clearance time. In patients with corticosteroids treatment, blood lymphocytes (odds ratio (OR) 0.792, 95% confidence interval (CI) 0.672–0.932, P = 0.005) and creatine kinase (CK) (OR 1.006, 95%CI 1.000-1.012, P = 0.038) were independent risk factors associated with death, with a sensitivity of 90.91% and 44.44% and a specificity of 70.75% and 94.05%, respectively. Conclusions In patients with Covid-19, corticosteroids treatment is associated with increased mortality and reduced rate of virus clearance.

ABSTRACT

Objective: To investigate the effectiveness of adjunctive corticosteroid therapy in patients with severe COVID-19. Methods: : We conducted a retrospective analysis of the difference in several outcomes between patients with severe COVID-19 who received corticosteroid therapy (the corticosteroid group) and patients with severe COVID-19 who did not receive corticosteroid therapy (the non-corticosteroid group). Results: : Seventy-five patients were included in this study. Of these, 47 patients were in the corticosteroid group and 28 patients were in the non-corticosteroid group. There were no differences between the two groups in the total length of hospital stay (LOS), the length of ICU stay, high-flow oxygen days, non-invasive ventilator days, invasive ventilation days, and mortality rate. Total lesion volume ratio, consolidation volume ratio and GGO volume ratio in the corticosteroid group decreased significantly on day 14, while those in the non-corticosteroid group did not show a significant decrease. Conclusions: : Our results show that adjunctive corticosteroid use did not significantly improve clinical outcomes in severe COVID-19 patients, but might promote the absorption of pulmonary lesions. Larger multicenter randomized controlled studies may be needed to confirm this.

ABSTRACT

Background: The effect of angiotensin-converting enzyme inhibitor/angiotensin receptor blockers (ACEI/ARB) on the COVID-19 remains controversial from clinic evidence. Methods: This is a retrospective, two-center case series of 198 consecutive COVID-19 patients with a history of hypertension. Results: Among 198 patients, 58 (29.3%) and 16 (8.1%) were on were on ARB and ACEI, respectively. Patients who were on ARB or ACEI/ARB had a significantly lower rate of severe illness and ARDS when compared with patients treated with ACEI alone or not receiving and RAAS blocker ( P <0.05). The Kaplan-Meier survival curve showed that patients with ARB in their antihypertensive regimen had a trend towards a higher survival rate when compared with individuals without ARB (adjusted hazard ratio, 0.27;95% CI, 0.07-1.02;P = 0.054). The Cox-regression analysis to compared ACEI vs. ARB groups showed a significantly lower mortality rate in the ARB group (adjusted hazard ratio, 0.03;95% CI, 0.00-0.58;P = 0.02). Conclusions: Using of ARB was associated with a reduced rate of severe illness and ARDS, indicating their potential protective impact in COVID-19.

ABSTRACT

The Coronavirus disease of 2019 (COVID-19) and measures to curb it created population-level changes in male-dominant impulsive and risky behaviors such as violent crimes and gambling. One possible explanation for this is that the pandemic has been stressful, and males, more so than females, tend to respond to stress by altering their focus on immediate versus delayed rewards, as reflected in their delay discounting rates. Delay discounting rates from healthy undergraduate students were collected twice during the pandemic. Discounting rates of males (n=190) but not of females (n=493) increased during the pandemic. Using machine learning, we show that prepandemic functional connectome predict increased discounting rates in males (n=88). Moreover, considering that delay discounting is associated with multiple psychiatric disorders, we found the same neural pattern that predicted increased discounting rates in this study, in secondary datasets of patients with major depression and schizophrenia. The findings point to sex-based differences in maladaptive delay discounting under real-world stress events, and to connectome-based neuromarkers of such effects. They can explain why there was a population-level increase in several impulsive and risky behaviors during the pandemic and point to intriguing questions about the shared underlying mechanisms of stress responses, psychiatric disorders and delay discounting.

ABSTRACT

Abnormal immunological indicators associated with disease severity and mortality in patients with COVID-19 have been reported in several observational studies. However, there are marked heterogeneities in patient characteristics and research methodologies in these studies. We aimed to provide an updated synthesis of the association between immune-related indicators and COVID-19 prognosis. We conducted an electronic search of PubMed, Scopus, Ovid, Willey, Web of Science, Cochrane library, and CNKI for studies reporting immunological and/or immune-related parameters, including hematological, inflammatory, coagulation, and biochemical variables, tested on hospital admission of COVID-19 patients with different severities and outcomes. A total of 145 studies were included in the current meta-analysis, with 26 immunological, 11 hematological, 5 inflammatory, 4 coagulation, and 10 biochemical variables reported. Of them, levels of cytokines, including IL-1ß, IL-1Ra, IL-2R, IL-4, IL-6, IL-8, IL-10, IL-18, TNF-α, IFN-γ, IgA, IgG, and CD4+ T/CD8+ T cell ratio, WBC, neutrophil, platelet, ESR, CRP, ferritin, SAA, D-dimer, FIB, and LDH were significantly increased in severely ill patients or non-survivors. Moreover, non-severely ill patients or survivors presented significantly higher counts of lymphocytes, monocytes, lymphocyte/monocyte ratio, eosinophils, CD3+ T,CD4+T and CD8+T cells, B cells, and NK cells. The currently updated meta-analysis primarily identified a hypercytokinemia profile with the severity and mortality of COVID-19 containing IL-1ß, IL-1Ra, IL-2R, IL-4, IL-6, IL-8, IL-10, IL-18, TNF-α, and IFN-γ. Impaired innate and adaptive immune responses, reflected by decreased eosinophils, lymphocytes, monocytes, B cells, NK cells, T cells, and their subtype CD4+ and CD8+ T cells, and augmented inflammation, coagulation dysfunction, and nonpulmonary organ injury, were marked features of patients with poor prognosis. Therefore, parameters of immune response dysfunction combined with inflammatory, coagulated, or nonpulmonary organ injury indicators may be more sensitive to predict severe patients and those non-survivors.

ABSTRACT

To investigate associations between parent-child relationships, children's externalizing and internalizing symptoms, and lifestyle responses to the COVID-19 epidemic, we conducted an online survey of a random, representative sample of residents with children aged 3-17 years during mid-March 2020 in Wuhan and Shanghai, China. A total of 1655 parents and children were surveyed with a response rate of 80.1% in the survey. During the epidemic, the frequency of children enquiring about the epidemic (AOR = 1.46, 95% CI: 1.04, 2.06), parents explaining the epidemic to them (AOR = 2.87, 95% CI: 1.80, 4.58), parents expressing negative emotions in front of them (AOR = 2.62; 95% CI = 2.08-3.30), and parents with more irritable attitudes (AOR = 1.93; 95% CI = 1.33-2.81) were significantly associated with children's externalizing symptoms. For internalizing symptoms, significant associations were found with worse parent-child closeness (AOR = 2.93; 95% CI = 1.80-4.79), the frequency of parents expressing negative emotions in front of them (AOR = 2.64; 95% CI = 1.68, 4.12), and more irritable attitudes (AOR = 2.24; 95% CI = 1.42-3.55). We also found that each indicator of parent-child relationships had the significantly similar associations with children's lifestyle behaviors. These findings suggest that improving parents' attitudes towards their children and parent-child closeness during the epidemic, especially among parents with lower educational levels, are important to ensure the wellbeing of children.

ABSTRACT

OBJECTIVES: Public health emergencies have caused significant psychological burden on nurse and affect their mental health. After the coronavirus disease 2019 pandemic, the nurse's mental health has been paid much attention. This study aims to investigate status and influencing factors for anxiety, depression, and insomnia in nurses during the normalized epidemic period, and to further compare the risk of anxiety, depression, and insomnia among nurses at different levels of hospitals between front-line epidemic nurses and other nurses so as to provide a basis for mental health work, nursing management, and relevant study in hospital. METHODS: A total of 4 237 nurses from all levels of hospitals in Hunan Province participated in the survey in December 2020. A self-designed anonymous questionnaire was used in this study. Anxiety, depression, and insomnia were assessed using Generalized Anxiety Disorder-7 items (GAD-7), Patient Health Questionnaire-9 items (PHQ-9), and Insomnia Severity Index (ISI), respectively. Descriptive statistical analysis was used to evaluate nurses' anxiety, depression, and insomnia; t-test, analysis of variance, and multiple linear stepwise regression analysis were used to analyze the influencing factors of nurses' anxiety, depression, and insomnia. RESULTS: The scores of GAD-7 among 4 237 nurses were 4.44±4.20, with 10.3% of them experienced moderate to severe level anxiety. The scores of PHQ-9 were 6.03±4.76, with 17.5% of them experienced moderate to severe level depressive symptom. The scores of ISI were 8.37±5.42, with 12.3% of them experienced moderate to severe insomnia. There were significant differences in GAD-7, PHQ-9, and ISI scores among different groups of hospital levels, gender, professional title, position, education level, night shifts, and family monthly income (all P<0.05). Marital status, whether to participate in the front-line, and whether to participate in psychology training groups were not associated with anxiety, depression, and insomnia (all P>0.05). Gender, hospital level, professional title, educational background, more night shifts, and family monthly income were the influencing factors for the GAD-7 and PHQ-9 scores. Gender, length of service, position, hospital level, educational background, night shifts in the last year, and family monthly income were the influencing factors for ISI score. CONCLUSIONS: There is no difference in the scores of the GAD-7, PHQ-9, and ISI between nurses whether to participate in the front-line, indicating that series of measures for front-line medical staff are effective in China.Meanwhile, some nurses experienced anxiety, depression, and insomnia, and attention should be paid to nurses with low position, more night shifts, lower-level hospitals, and families with low income. It is recommended that management policies, psychological support, and human resource protection should be given to relieve the pressure and maintain the mental health of nurses. At the same time, it is necessary to make mental health knowledge training as a routine training when responding to public health emergencies.

ABSTRACT

Among 78 laboratory-confirmed cases, we found two asymptomatic infections. One patient was discharged within 14 days after treatment. Another patient was discharged 25 days after treatment, and his RT-PCR test was still positive on the 15th day. We found that there may be virus carriers in the asymptomatic population with an epidemiological contact history. After 14 days of isolation, those with asymptomatic infection may still carry the virus, which means a risk of transmission, presenting a new challenge for the management of home isolation.

ABSTRACT

BACKGROUND: The novel coronavirus (COVID-19) pandemic has affected humans worldwide and led to unprecedented stress and mortality. Detrimental effects of the pandemic on mental health, including risk of post-traumatic stress disorder (PTSD), have become an increasing concern. The identification of prospective neurobiological vulnerability markers for developing PTSD symptom during the pandemic is thus of high importance. METHODS: Before the COVID-19 outbreak (September 20, 2019-January 11, 2020), some healthy participants underwent resting-state functional connectivity MRI (rs-fcMRI) acquisition. We assessed the PTSD symptomology of these individuals during the peak of COVID-19 pandemic (February 21, 2020-February 28, 2020) in China. This pseudo-prospective cohort design allowed us to test whether the pre-pandemic neural connectome status could predict the risk of developing PTSD symptom during the pandemic. RESULTS: A total of 5.60% of participants (n = 42) were identified as being high-risk to develop PTSD symptom and 12.00% (n = 90) exhibited critical levels of PTSD symptoms during the COVID-19 pandemic. Pre-pandemic measures of functional connectivity (the neural connectome) prospectively classified those with heightened risk to develop PTSD symptom from matched controls (Accuracy = 76.19%, Sensitivity = 80.95%, Specificity = 71.43%). The trained classifier generalized to an independent sample. Continuous prediction models revealed that the same connectome could accurately predict the severity of PTSD symptoms within individuals (r 2 = 0.31p<.0). CONCLUSIONS: This study confirms COVID-19 break as a crucial stressor to bring risks developing PTSD symptom and demonstrates that brain functional markers can prospectively identify individuals at risk to develop PTSD symptom.

ABSTRACT

BACKGROUND: This study was performed to investigate clinical features of patients with severe SARS-CoV-2 pneumonia and identify risk factors for converting to severe cases in those who had mild to moderate diseases at the start of the pandemic in China. METHODS: In this retrospective, multicenter cohort study, patients with mild to moderate SARS-CoV-2 pneumonia were included. Demographic data, symptoms, laboratory values, and clinical outcomes were collected. Data were compared between non-severe and severe patients. RESULTS: 58 patients were included in the final analysis. Compared with non-severe cases, severe patients with SARS-CoV-2 pneumonia had a longer: time to clinical recovery (12·9 ± 4·4 vs 8·3 ± 4·7; P = 0·0011), duration of viral shedding (15·7 ± 6·7 vs 11·8 ± 5·0; P = 0·0183), and hospital stay (20·7 ± 1·2 vs 14·4 ± 4·3; P = 0·0211). Multivariate logistic regression indicated that lymphocyte count was significantly associated with the rate of converting to severe cases (odds ratio 1·28, 95%CI 1·06-1·54, per 0·1 ×  109/L reduced; P = 0·007), while using of low-to-moderate doses of systematic corticosteroids was associated with reduced likelihood of converting to a severe case (odds ratio 0·14, 95%CI 0·02-0·80; P = 0·0275). CONCLUSIONS: The low peripheral blood lymphocyte count was an independent risk factor for SARS-CoV-2 pneumonia patients converting to severe cases. However, this study was carried out right after the start of the pandemic with small sample size. Further prospective studies are warranted to confirm these findings.

ABSTRACT

When a biological public health event breaks out, due to the characteristics of their work, doctors and nurses must face risks directly when the situation is unknown. Their difficulties and psychological pressure are unimaginable. However, few studies have investigated the difficulties encountered by those doctors and nurses and their requirements for psychological interventions. This study aimed to explore the difficulties and psychological intervention needs of doctors and nurses during the new biological public health events in China in 2019. We carried out a qualitative study using a phenomenological approach. We used convenience sampling to identify participants who provided direct care and treatment for patients with biological events such as coronavirus disease 2019 (COVID-19). They participated in semi-structured, in-depth face-to-face interviews. The interviews were transcribed and analyzed using Colaizzi's seven-step method. Analysis of this study was divided into the difficulties encountered by doctors and nurses and their mental health need. The difficulties encountered by doctors and nurses included four themes: being worried about the impact on others, lack of knowledge and skills, difficult patients, being socially isolated, and the feeling of uncertainty. The mental health need was summarized into two parts, needs expressed by doctors and nurses and needs observed by researchers. Doctors and nurses mostly did not feel that they needed any psychological support, but the researchers noticed several signs of stress or potential mental health problems among interviewees. Doctors and nurses faced significant complex and multidimensional difficulties. Many denied needing psychological support, even though the researchers noted signs that it might be helpful. Interventions and support strategies that involve mental health promotion activities should consider individual needs related to doctors and nurses' situation.
