ABSTRACT

Longitudinal alterations of mental health problems still lack clarity among frontline medical staff treating patients with coronavirus disease 2019 (COVID-19). Mental health surveys were conducted from February 19 to 23 (n = 222), from March 3 to 10 (n = 364), from March 15 to 22 (n = 446), and from March 25 to April 3 (n = 174), 2020, of medical staff working at medical staff at a specializ ed hospital to admit patients with COVID-19 in China. The rate of reporting anxiety remained unchanged within 6 weeks, but the rate of reporting depression increased at week 3 and remained unchanged afterwards. Age was an independent risk factor for symptoms of anxiety and depression, and working days were independent risk factors for symptoms of depression. These results highlight the importance of dynamic assessment. Copyright © 2022, Universidade de Sao Paulo. Museu de Zoologia. All rights reserved.

ABSTRACT

The coronavirus disease 2019 (COVID-19) pandemic has brought severe challenges to global public health. Many studies have shown that obesity plays a vital role in the occurrence and development of COVID-19. Obesity exacerbates COVID-19, leading to increased intensive care unit hospitalization rate, high demand for invasive mechanical ventilation, and high mortality. The mechanisms of interaction between obesity and COVID-19 involve inflammation, immune response, changes in pulmonary dynamics, disruptions of receptor ligands, and dysfunction of endothelial cells. Therefore, for obese patients with COVID-19, the degree of obesity and related comorbidities should be evaluated. Treatment methods such as administration of anticoagulants and anti-inflammatory drugs like glucocorticoids and airway management should be actively initiated. We should also pay attention to long-Term prognosis and vaccine immunity and actively address the physical and psychological problems caused by longterm staying-At-home during the pandemic. The present study summarized the research to investigate the role of obesity in the incidence and progression of COVID-19 and the psychosocial impact and treatment options for obese patients with COVID-19, to guide the understanding and management of the disease.

ABSTRACT

The danmaku text is a popular interactive mode of instantaneous video comment. Websites with danmaku texts have been widely used recently, and this vast number of texts can be regarded as a short text mining resource. This paper uses Perplexity and Renyi entropy to evaluate the BTM (Biterm Topic Model), by extracting the topic from the danmaku texts to explore the evolution of danmaku text topics in videos relevant to COVID-19. The results show that Renyi entropy is an effective way to decide the optimal number of topics, and the topics captured by BTM indicate that video viewers showed positive attitudes in the face of this public health emergency. © 2022 IEEE.

ABSTRACT

The outbreak of COVID-19 has led to a sharp increase in the demand for disposable medical protective clothing in the short term. In order to shorten the marketing cycle, a large number of domestic disposable medical protective clothing products have been sterilized by electron beam irradiation, which is more efficient than ethylene oxide sterilization. However, the performance of such clothing must adhere to strict requirements and the process parameters of this sterilization method still lack systematic data support. In order to ensure the reliability of electron beam sterilization of disposable medical protective clothing, research on a corresponding process was carried out. Typical disposable medical protective clothing available on the market made of polypropylene (PP) and coated with polyethylene (PE) was selected as the material studied. An appropriate method was selected to establish the corresponding sterilization dose with reference to the standard methods—“Disposable medical protective clothing irradiation sterilization emergency specification (temporary)”and“ISO 11137-2:2013 Sterilization of health care products—Radiation—Part 2: Establishing the sterilization dose.”The change in material properties after irradiation sterilization with different absorbed doses was studied. Based on the obtained parameters, an algorithm for the average absorbed dose on irradiation by an irradiation electron linac was proposed. Results showed that absorbed doses of 20.3 kGy and 31.5 kGy allowed the products to achieve sterility assurance levels of 10−3 and 10−6, respectively. The material performance of the products after irradiation at 25.0 kGy, 30.0 kGy and 35.0 kGy were able to meet national standard requirements such as elongation at break, breaking strength, impermeability, and filtration efficiency. Thus, a satisfactory electron beam irradiation sterilization process for medical disposable protective clothing has been established. © 2021 The authors.

ABSTRACT

Objective: To compare the clinical features of Omicron and Delta cases, so as to provide scientific basis for the prevention and treatment of COVID-19. Methods: The case-control study method was used to retrospectively analyze the clinical data of the Omicron cases admitted to the designated hospital for the treatment of COVID-19 in Xi'an from December 2021 to January 2022. and the Delta cases admitted during the same period were used as the control group. The demographic data, epidemiological history, vaccination status, clinical characteristics, laboratory tests, nucleic acid and antibody levels, and outcomes of patients in the two groups were collected and compared. Results: A total of 21 patients were included in the study, 5 were Omicron patients and 16 were Delta cases. The mean age of the patients in the two groups were (38.20±15.07) and (37.69±10.39) years, respectively.The time interval between the last vaccination and the diagnosis was (145.40±77.92) days and (159.00±99.74) days, respectively. For the initial symptoms, the patients with Omicron were mainly characterized by throat discomfort (3, 60%), cough and sputum (2, 40%), and the patients with Delta were mainly characterized by throat discomfort (5, 31.25%), fatigue (5, 31.25%), cough and sputum (4, 25%). On admission, laboratory tests showed that 60% of Omicron patients had low lymphocytes and elevated erythrocyte sedimentation rate, and 50% of patients in the delta group had elevated hemoglobin. The Ct values of ORFlab gene, N gene and E gene with Omicron were lower than those with Delta. And the difference of E gene between the two groups was statistically significant (t=-2.711, P=0.024). IgG antibody levels increased in both groups.The time for nucleic acid to turn negative with Omicron was (28.20±5.89) days, and it was (18.50±7.73) days with Delta, and the difference between the groups was statistically significant (t=2.565, P=0.019). The length of hospitalization with Omicron was (30.60±4.88) days, and that with Delta was (22.13±7.81) days, and the difference was statistically significant (t=2.270, P =0.035). Conclusions: The initial symptoms of Omicron patients are mainly throat discomfort, cough and sputum. The clinical manifestations are generally mild. The nucleic acid test Ct value is lower. The time for nucleic acid to turn negative and the time for hospitalization are longer, and the potential infectiousness is stronger. Those eligible for vaccination should complete the full course of vaccination and booster vaccination as soon as possible. At the same time, the management of "early detection, early reporting, early isolation, and early treatment" should be implemented.

ABSTRACT

There are two general challenges for social planners in combating a pandemic: how to increase antipandemic consumptions that exhibit widespread externality, and how to trade-off between efficiency and equality. We show that these conventional concerns need not always be valid. We consider a market for antipandemic resources, where two groups of people can be either high or low in their (diminishing) marginal private returns and the suppliers are price takers with increasing marginal costs. Our basic result is that the socially efficient consumption is higher for the low type but can be lower for the high type, relative to the competitive equilibrium. This is because the high type's consumption is crowded out by that of low type who turns out to be marginally more productive in generating social benefits. Therefore, more equal consumptions can be efficient. Discriminatory subsidies in favor of the low type can maximize social welfare while yielding more equal consumptions. Quantity forcing or rationing can increase both social welfare and equality. In addition, policy portfolios combining uniform subsidy with quantity forcing or rationing can achieve full efficiency. Moreover, the main results are robust to alternative demand-side specifications, as long as the groups are sufficiently heterogenous in their overall consumption incentives.

ABSTRACT

Background: Eight pm on April 13, 2022,a10:1 mixed test tube was found to be positive in the COVID-19 nucleic acid test site set up outside the hospital. In order to identify the infected case and control the spread of COVID-19 rapidly, we conducted this emergency investigation. Methods: According to the National COVID-19 Control and Prevention Protocol (8th edition), Guideline on Emergency Response to COVID-19 Case Found in Hospital in Shandong Province, and the Emergency Response Plan for COVID-19 in our hospital, information reporting, hospitalblockading, potential COVID- 19 cases tracing, close contact screening, environmental sampling and disinfecting, COVID-19 nucleic acid testing and risk assessment were carried out by our team. Results: A female COVID-19 case aged 50 years was identified. She is aodd-jobber who works in the labour market near the hospital. The virus strain was sequenced as Omicron BA.2. A total of 65 close contacts was controlled in a hotel. The COVID-19 nucleic acid test results for all the staff of hospital, environmental samples were negative. The risk of COVID-19 spread was controlled and the hospital restarted of clinical activities as normal at 8 am on April 14 after blockaded for 12 hours. Inthe following 7 days, the staff of the hospital were tested for COVID-19 nucleic acid twice a day, and the results were negative. Then the testing frequency changed to once a day. Conclusion: Formulating detailed and feasible COVID-19 emergency response plans based on the requirements of the public documents and the actual conditions of the hospital, is useful to improve the efficiency of emergency response to COVID-19 cases and save time for control of COVID-19 spread and restart the clinical activities of hospital. © 2022 Shandong Yinbao Technology Co.

ABSTRACT

Rationale Difficult to treat asthma (DTTA) is asthma that is uncontrolled despite medium/high ICSLABA treatment and/or maintenance oral corticosteroids (OCS);severe asthma is a subset. Previous research suggests that anxiety and depression are common among patients with severe asthma;these may impact asthma control and quality of life. Screening for anxiety and depression has been recommended, followed by appropriate psychiatrist/psychologist referral. However, little is known about whether the mental health support needs of people with DTTA are being met, and any attributable health service utilisation. The aims of this study were to explore mental health issues, and healthcare utilization, in people with DTTA within a nationally-representative population of people with a diagnosis of asthma.Methods The DTTA Survey was a cross-sectional survey in February-March 2021 of 5457 participants aged ≥18 years with current asthma, randomly selected from a large web-based survey panel of adult Australians. All survey participants answered demographic questions and questions regarding asthma symptoms, medications and health service use, with additional questions for those with DTTA. DTTA was identified based on ERS/ATS criteria.Mental status was assessed via reported comorbidities, mental health referrals and treatment, and the Hospital Anxiety and Depression Scale (HADS) which assesses feelings in the previous week. The Consultation and Relational Empathy (CARE) measure was also used to gauge participants' perceptions about the consultation process with their general practitioner.Results 1170 (21.4%) of participants had DTTA. Of these 56.8% (664/1170) were female (Table). The proportions of DTTA participants who reported being told by a doctor/nurse that they had anxiety or depression, and selected “have at present” for these diagnoses, were 35.9% and 28.9% respectively;21.8% indicated both. However, by HADS, 63.4% self-reported current anxiety symptoms and 39.9% current depression symptoms. 50% reported feeling more anxious about their asthma due to COVID19. Overall, 47.9% of those with DTTA (561/1170) reported treatment for anxiety or depression in the previous year. Treatments included medication (72.7%);Cognitive Behavioural Therapy (42.8%);and mindfulness training (23.9%). Concerning mental health support, 611 participants (52.2%) had consulted with a psychologist or counsellor in last 5 years;38.8% of those visits were within the previous 3 months. Over half these consultations (52.5%) were initiated by the participant, and 33.6% by the GP. Conclusion The findings from this representative population survey provide insights regarding prevalence and management of anxiety and depression among people with DTTA, and may assist clinicians in supporting their mental health needs.

ABSTRACT

Methods: Veterans completed the 8-week MBSR incorporated with Integrative Health interventions, including health coaching and other wellbeing services at a VA Medical center. Participants received objective assessments at baseline and after the 8-week course for PHQ-9,GAD-7, PSS, and SF-36. At the end of the program, participants completed a qualitative survey to evaluate their motivation and program experiences. Results: Among the fifty-seven participants who completed the MBSR between 2019 and 2020, thirty-nine participants completed the course in traditional face-to-face format, and seventeen enrolled throughWebEx platformduring pandemic. Across all MBSR participants, statistically significant changes were found at completion, including lower levels of perceived stress (d = 1.018 [0.672, 1.357]), improvements to anxiety (d = 1.161 [0.818, 1.498]), and depression (d = 0.926, [0.609, 1.237]) symptoms. Similarly, perceptions of health also showed meaningful improvements in the categories of SF-General Health (d = -0.692, [-1.015, -0.363]), SF-Vitality (d = -0.549, [-0.860, -0.233]), SF-Social Functioning (d = -0.766, [-1.095, -0.429]), SF-Role Emotional (d = -0.657, [-0.976, -0.331]), SFMental Health (d = -1.740, [-1.067, -0.406]). There was no statistical difference between outcomes for participants who utilized telehealth and face-to-face format, suggesting that Telehealth MBSR within an IHC setting is plausible. Four major clusters of themes were identified: improve isolation and loneliness, improve stress from pandemic, endorse course content and structure, and technical challenging of telehealth. Background: Determine if mindfulness-based stress reduction (MBSR) in an integrative healthcare (IHC) clinical setting can improve patients' depression, stress, anxiety, quality of life, and other wellbeing during COVID 19 pandemic. Conclusion: Participating in the MBSR within an integrative healthcare setting can be successfully delivered through telehealth and in person, resulting in clinical improvements of depression, anxiety, perceptions of stress, and quality-of-life. Face-to-face and Telehealth MBSR with IHC focus have promising potential to improve Veterans' mental health burden and overall wellbeing.

ABSTRACT

There are currently 449,368,894 confirmed cases and 6,033,022 deaths from the coronavirus COVID- 19 outbreak as of March 08, 2022, leaving 443,335,872 survivors. The actual number of global COVID- 19 cases is likely to be two to three times higher than reported. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the novel virus responsible for the coronavirus disease 2019 (COVID-19) pandemic, resulting in unprecedented global health and economic crises with massive social impacts and massively strained health resources globally. COVID-19 is well recognized as a multi-organ disease with a broad spectrum of manifestations. During the early phases of the pandemic, patient advocacy groups, many members of which identify themselves as long COVID, have helped contribute to the recognition of post-acute COVID-19 Neurological Syndrome (PCNS), a syndrome characterized by persistent symptoms and delayed or long-term complications beyond four weeks from the onset of symptoms. This paper provides a comprehensive review of the current literature on post-acute COVID- 19 Neurological Syndrome, its pathophysiology, and its organ-specific sequelae. We explore the shared pathobiological profiles of stroke and COVID-19 involvement in the brain with a significant impact on the long-term care of both groups of survivors. The paper will discuss the role of universal biomarker, serial systemic immune-inflammatory indices (SSIIi) in the context of PCNS and potential implications in post-stroke neurological complications to introduce a systems biology approach to promote brain health for all globally.

ABSTRACT

The outbreak of SARS-CoV-2 continues to pose a serious threat to human health and social and economic stability. In this study, we established an anti-coronavirus drug screening platform based on the Homogeneous Time Resolved Fluorescence (HTRF) technology and the interaction between the coronavirus S protein and its host receptor ACE2. This platform is a rapid, sensitive, specific, and high throughput system. With this platform, we screened two compound libraries of 2,864 molecules and identified three potential anti-coronavirus compounds: tannic acid (TA), TS-1276 (anthraquinone), and TS-984 (9-Methoxycanthin-6-one). Our in vitro validation experiments indicated that TS-984 strongly inhibits the interaction of the coronavirus S-protein and the human cell ACE2 receptor. This data suggests that TS-984 is a potent blocker of the interaction between the S-protein and ACE2, which might have the potential to be developed into an effective anti-coronavirus drug.

ABSTRACT

Macroeconomic stability is the core concept of sustainable development. However, the coronavirus disease (COVID-19) pandemic has caused government debt problems worldwide. In this context, it is of practical significance to study the impact of government debt on economic growth and fluctuations. Based on panel data of 30 provinces in China from 2012 to 2019, we used the Mann–Kendall method and Kernel Density estimation to analyze the temporal and spatial evolution of China’s provincial government debt ratio and adopted a panel model and HP filtering method to study the impact of provincial government debt on economic growth and fluctuation. Our findings indicate that, during the sample period, China’s provincial government debt promoted economic growth and the regression coefficient (0.024) was significant. From different regional perspectives, the promotion effect of the central region (0.027) is higher than that of the eastern (0.020) and western regions (0.023). There is a nonlinear relationship between China’s provincial government debt and economic growth, showing an inverted “U-shaped” curve. Fluctuations in government debt aggravate economic volatility, with a coefficient of 0.009;tax burden fluctuation and population growth rate aggravate economic changes. In contrast, the optimization of the province’s industrial structure and the improvement of the opening level of provinces slow down economic fluctuations. © 2022 by the authors.

ABSTRACT

Objective: To investigate the clinical characteristics, treatment and outcome of elderly patients with COVID-19. Methods: We made a retrospective analysis of the clinical data of elderly patients with COVID-19 admitted by the National Anti-epidemic Medical Team of The First Affiliated Hospital of Xi'an Jiaotong University in Department of the seventh ward of Renmin Hospital of Wuhan University between February 9 and March 15, 2020. We fully extracted the patients' demographics, epidemiological characteristics, clinical manifestations, laboratory examination, imaging performance, treatment and outcomes. Results: In this study we included a total of 30 patients(18 males and 12 females), with an average age of(71.1±14.4) years. Their underlying diseases included cardiovascular and cerebrovascular diseases(23 patients), chronic pulmonary disease(3 patients), digestive disease(2 patients), diabetes mellitus(3 patients), and chronic kidney disease(1 patients). Before admission, 22 patients received oral medication. The initial symptoms were fever and cough. The peak body temperature averaged(38.4±0.6)℃ The mean time from symptom onset to hospitalization was 15.0±7.7 days. The clinical classification was mainly severe type in 26 patients(87%). Laboratory examination revealed lower lymphocyte count(0.7±0.2)×109/L, and higher blood D-D dimer lever(6.9±13)μg/L. Serum lactate dehydrogenase(LDH) significantly increased(310±136)U/L. Serum C-reactive protein(61±52)mg/L and erythrocyte sedimentation rate(ESR)(66±38)mmol/L slightly increased. Imaging performance revealed that diffuse lesions were located in bilateral pulmonary parenchyma(22 patients) and in single pulmonary parenchyma(7 patients). Ground-glass opacity was found in all the patients, and the average number of CT examination during hospitalization was 3.5±1.3. Viral load revealed that nucleic acid in nasopharyngeal swabs of 30 patients was all positive, nucleic acid in the feces of 6 patients was positive, and nucleic acid in nasopharyngeal swab of 1 patient was positive, whose nucleic acid in alveolar lavage fluid was negative. Serum IgG antibody level was(157.5±29.2)AU/mL and IgM antibody level was(69.0±148.7)AU/mL. Complications included ARDS in 5 patients, AKI in 5 patients, cardiac injury in 3 patients, shock in 2 patients, nosocomial infection in 3 patients, coagulation disorder in 3 patients, and gastrointestinal bleeding in 3 patients. Finally, 5 patients received non-invasive mechanical ventilation and 2 patients received invasive mechanical ventilation. Another 2 patients underwent CRRT and 1 patient received CRRT plus ECMO. Of the 3 patients with critical type, 2 died and 1 survived. There were 25 patients who turned from severe type into normal type/light type, and 1 patient finally died(turned from severe type into critical type). In the end, 15 patients were cured and discharged. The average time of viral nucleic acid from positive to negative was 12.4±5.6 and the average time of lesion absorption in computer tomography was 16.9±5.8 days. The total hospital stay was 22.9±8.1 days, and the 28-day mortality rate was 6.7%. Conclusion: COVID-19 in elderly patients is mostly severe and its initial symptoms are still fever and cough. Patients should be immediately hospitalized when symptoms develop. The time of viral nucleic acid transformation and imaging improvement is longer than that of others. The mortality in critically ill patients is higher than that of others. Clinicians should pay more attention to the elderly people. © 2021, Editorial Board of Journal of Xi'an Jiaotong University (Medical Sciences). All right reserved.

ABSTRACT

Since the outbreak of COVID-19, the detection of wearing masks has become a necessary measure for epidemic prevention and control. To solve the problem about low accuracy of mask wearing detection under dim lighting conditions, a method of mask wearing detection combining attention mechanism with YOLOv5 network model is proposed, which uses image enhancement algorithm to pre-process the training set pictures, and then put these pictures to YOLOv5 network with attention mechanism for iterative training. After training, the optimal weight is saved and the best model is used to test the accuracy on the test set. The experimental results show that the YOLOv5 network model with attention mechanism can effectively enhance the extraction of key points such as face and mask and improve the robustness of the model. The accuracy of mask wearing can reach 92% under dim lighting conditions, which can effectively meet the actual needs.

ABSTRACT

China has made remarkable progress in reducing tuberculosis cases and deaths during the past three decades;however, it is still far from achieving the targets set out in the WHO End TB Strategy Since the 2000s, China has tried to transform its vertical tuberculosis control programme led by the Chinese Center for Disease Control and Prevention (CDC) into an integrated system under the collaboration of CDC, tuberculosis-designated hospitals, and primary health centres. Such a transition has faced many challenges. Profit-driven practices in hospitals designated to tuberculosis and an absence of adequate tuberculosis-related training for health professionals are partially jeopardising the quality of tuberculosis care. In addition, primary health-care providers are not incentivised to make referrals and manage cases effectively. The CDC does not have the administrative power to influence hospital practices or deploy resources to support community-based tuberculosis control activities. Furthermore, an absence of policy coherence and effective coordination causes challenges for quality tuberculosis care that is affordable and accessible. Improving policy dialogues and multi-level coordination within the government is fundamental to successfully ending tuberculosis in China and other countries facing similar challenges.

ABSTRACT

As the coronavirus 2019 (COVID-19) pandemic continues to be a global public health emergency, many individuals are facing mental health issues due to the many challenges that accompany this pandemic. Previous studies report that many people around the world are experiencing high levels of stress and therefore struggling to manage their emotions and mental well-being. While there are numerous different factors that influence how an individual may be dealing with the pandemic related stressors, one factor that does seem to influence their stress level is their coping mechanisms. In this study, we aim to understand people's perceived stress level during the COVID-19 pandemic, their coping mechanisms, and whether these constructs were influenced by their personality and other individual differences. To investigate these questions, we conducted an online survey in the summer of 2020 where study participants were asked to report on their mental well-being. Study results obtained from statistical models, including Pearson Correlation Test, Regression models, and Random Forest model, show that there is a significant difference between individuals' stress level and their coping mechanisms. In addition, we found that individuals' personality traits seem to influence their stress level as well as what type of coping mechanism they may be using during the pandemic. These findings can provide awareness to individuals as well as for public and mental health professionals who may be working or providing support to different populations during the COVID-19 pandemic. © 2021 ACM.

ABSTRACT

Environmental factors such as temperature and relative humidity can affect the inactivation and transmission of coronaviruses. By reviewing medical experiments on virus survival and virus transmission between infected and susceptible species in different temperature and humidity conditions, this study explores the influence of temperature and relative humidity on the survival and transmission of viruses, and provides suggestions, with experimental evidence, for the environmental control measures of Coronavirus Disease 2019. The results indicated that (1) virus viability and infectivity is increased at a low temperature of 5 â„ƒ and reduced at higher temperatures. (2) Virus survival and transmission is highly efficient in a dry environment with low relative humidity, and also in a wet environment with high relative humidity, and it is minimal at intermediate relative humidity. Therefore, in indoor environments, the lack of heating in winter or overventilation, leading to low indoor temperature, can help virus survival and help susceptible people being infected. On the contrary, modulating the indoor relative humidity at an intermediate level is conducive to curb epidemic outbreaks.

ABSTRACT

Due to line-of-sight communication links and distributed deployment, Unmanned Aerial Vehicles (UAVs) have attracted substantial interest in agile Mobile Edge Computing (MEC) service provision. In this paper, by clustering multiple users into independent communities based on their geographic locations, we design a 5G-enabled UAV-to-community offloading system. A system throughput maximization problem is formulated, subjected to the transmission rate, atomicity of tasks and speed of UAVs. By relaxing the transmission rate constraint, the mixed integer non-linear program is transformed into two subproblems. We first develop an average throughput maximization-based auction algorithm to determine the trajectory of UAVs, where a community-based latency approximation algorithm is developed to regulate the designed auction bidding. Then, a dynamic task admission algorithm is proposed to solve the task scheduling subproblem within one community. Performance analyses demonstrate that our designed auction bidding can guarantee user truthfulness, and can be fulfilled in polynomial time. Extensive simulations based on real-world data in health monitoring and online YouTube video services show that our proposed algorithm is able to maximize the system throughput while guaranteeing the fraction of served users.
