Paternal De Novo Variant of TAOK1 in a Fetus With Structural Brain Abnormalities.

A dilated lateral ventricle is a relatively common finding on prenatal ultrasound, and the causes are complex. We aimed to explore the etiology of a fetus with a dilated lateral ventricle. Trio whole-exome sequencing was performed to detect causative variants. A de novo variant of TAOK1 (NM_020791.2: c.227A>G) was detected in the proband and evaluated for potential functional impacts using a variety of prediction tools. Droplet digital polymerase chain reaction was used to exclude the parental mosaicism and to verify the phasing of the de novo variant. Based on peripheral blood analysis, the parents did not exhibit mosaicism at this site, and the de novo variant was paternally derived. Here, we describe a fetus with a de novo likely pathogenic variant of TAOK1 who had a dilated lateral ventricle and a series of particular phenotypes. This case expands the clinical spectrum of TAOK1-associated disorders. We propose a method for solving genetic disorders in which the responsible genes have not yet gone through ClinGen curation, particularly for prenatal cases.

Clinical practice guidelines and expert consensus statements on rehabilitation for patients with COVID-19: protocol for a systematic review.

INTRODUCTION: COVID-19 is a highly infectious disease, characterised by respiratory, physical and psychological dysfunctions. Rehabilitation could effectively alleviate the symptoms and promote recovery of the physical and mental health of patients with COVID-19. Recently, rehabilitation medical institutions have issued clinical practice guidelines (CPGs) and expert consensus statements involving recommendations for rehabilitation assessments and rehabilitation therapies for COVID-19. This systematic review aims to assess the methodological quality and reporting quality of the guidance documents, evaluate the heterogeneity of the recommendations and summarise the recommendations with respect to rehabilitation assessments and rehabilitation therapies for COVID-19 to provide a quick reference for front-line clinicians, therapists and patients as well as reasonable suggestions for future guidelines. METHODS AND ANALYSIS: The electronic databases including PubMed, Embase, Chinese Biomedical Literature Database (CBM), Chinese Science and Technology Periodical Database (VIP), Wanfang Database and China National Knowledge Infrastructure (CNKI) and websites of governments or organisations (eg, National Guideline Clearinghouse, Guidelines International Network, National Institute for Health and Clinical Excellence, Scottish Intercollegiate Guidelines Network and WHO) will be searched for eligible CPGs and expert consensus statements from inception to August 2022. CPGs and expert consensus statements published in Chinese or English and presenting recommendations for modern functional rehabilitation techniques and/or traditional Chinese medicine rehabilitation techniques for COVID-19 will be included. Reviews, interpretations, old versions of CPGs and expert consensus statements and those for the management of other diseases during the pandemic will be excluded. Two reviewers will independently review each article, extract data, appraise the methodological quality following the Appraisal of Guidelines for Research & Evaluation II tool and assess the reporting quality with the Reporting Items for Practice Guidelines in Healthcare statement. The Measurement Scale of Rate of Agreement will be used to evaluate the heterogeneity of the recommendations in different CPGs and expert consensus statements. Agreement between reviewers will be calculated using the intraclass correlation coefficient. We will also summarise the recommendations for rehabilitation in patients with COVID-19. The results will be narratively described and presented as tables or figures. ETHICS AND DISSEMINATION: Ethics approval is not needed for this systematic review because information from published documents will be used. The findings will be submitted for publication in a peer-reviewed journal and reported in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. PROSPERO REGISTRATION NUMBER: CRD42020190761.

Research on the Differences in the Value Correlation of Accounting Data Under the Background of COVID-19: Comparative Evidence From China and Thailand

In today's highly developed world of financial globalization, international capital flows in my country and the entire Asia-Pacific region are gradually increasing. The stock market is an important part of the capital market. The stock market has gradually improved its capital liquidity. With the improvement of the investment environment in the international capital market and the gradual relaxation of capital controls, with the development of the "Belt and Road" development concept, Thailand has gradually chosen to buy and sell shares of Chinese investors. What investors need to consider is how to achieve capital appreciation. Investors need to consider how to achieve capital appreciation. However, a sudden new crown pneumonia epidemic broke the peace and excitement that the New Year should have, and also brought a great impact on the stock market. Of course, the stock market is affected by many factors. There are some problems here, such as the experience of the Chinese stock market.

The Impact of Digital Technology on the Optimization of Higher Education Teaching Models in an Epidemic Environment

The Corona Virus Disease 2019 epidemic broke out in 2020, and digital technologies pervaded all aspects of people’s lives, resulting in a significant shift in how education is delivered. The importance and role of digital technologies and online learning are highlighted in this paper, which examines the challenges posed by the sudden epidemic crisis to higher education institutions, analyses the factors that universities must consider in order to effectively create flexible learning pathways, and examines the challenges posed by the sudden epidemic crisis to higher education institutions. In the postepidemic era, the use of the Internet and online teaching platforms by university faculty to integrate online and offline teaching has not only facilitated the construction of “golden courses” but also added impetus to teaching reform, and digital technology-based teaching models have provided higher education practitioners with the opportunity to rethink scholarship and innovative teaching. In this paper, we propose a personalized learning resource recommendation system that includes user profiles to fully explore and analyze users’ learning behaviors and cognitive characteristics and enhance the depth and breadth of personalized education with the help of the Internet and artificial intelligence technologies in order to provide meaningful information and thoughts for higher education institutions to discuss and adapt to the education model in the postepidemic era. The goal is to provide useful information and ideas for higher education institutions to discuss and adapt to the postepidemic education paradigm.

Longitudinal associations between multiple mental health problems and suicidal ideation among university students during the COVID-19 pandemic.

BACKGROUND: Recent research suggested that COVID-19-related multiple mental health problems were associated with an increased risk for suicidal ideations (SIs), but population-based data demonstrating these associations are scarce. This study aimed to estimate the cumulative effects of psychological risk factors on SIs during the outbreak and remission periods of COVID-19 using a cumulative risk model, as well as sex differences. METHODS: A total of 68,685 college students in China participated in the survey during two phases of the pandemic (T1 and T2). Mental health risks (acute stress, depression, anxiety, insomnia, and obsessive-compulsive symptoms) and sociodemographic characteristics were measured at T1, and SIs were assessed at T1 and T2. Hierarchical regression analysis was used to determine the combined effect of multiple mental health problems on SIs at T1 and T2. RESULTS: The prevalence of SIs increased from the early periods of the COVID-19 pandemic (7.6%) to the later periods (10.0%). Depression was a powerful risk factor for SIs during the COVID-19 pandemic. Individuals with >3 mental risks would be most likely to experience rapidly increasing SIs during the early periods of the COVID-19 pandemic. Sex exerted different effects on the cumulative risk model of SIs. CONCLUSIONS: Interventions, such as mental health education and improving utilization of student support services, should be implemented. There is a crucial need for early intervention and prevention efforts aimed at males with greater than three mental health problems.

COVID-19 induces new-onset insulin resistance and lipid metabolic dysregulation via regulation of secreted metabolic factors.

Abnormal glucose and lipid metabolism in COVID-19 patients were recently reported with unclear mechanism. In this study, we retrospectively investigated a cohort of COVID-19 patients without pre-existing metabolic-related diseases, and found new-onset insulin resistance, hyperglycemia, and decreased HDL-C in these patients. Mechanistically, SARS-CoV-2 infection increased the expression of RE1-silencing transcription factor (REST), which modulated the expression of secreted metabolic factors including myeloperoxidase, apelin, and myostatin at the transcriptional level, resulting in the perturbation of glucose and lipid metabolism. Furthermore, several lipids, including (±)5-HETE, (±)12-HETE, propionic acid, and isobutyric acid were identified as the potential biomarkers of COVID-19-induced metabolic dysregulation, especially in insulin resistance. Taken together, our study revealed insulin resistance as the direct cause of hyperglycemia upon COVID-19, and further illustrated the underlying mechanisms, providing potential therapeutic targets for COVID-19-induced metabolic complications.

Imatinib and methazolamide ameliorate COVID-19-induced metabolic complications via elevating ACE2 enzymatic activity and inhibiting viral entry.

Coronavirus disease 2019 (COVID-19) represents a systemic disease that may cause severe metabolic complications in multiple tissues including liver, kidney, and cardiovascular system. However, the underlying mechanisms and optimal treatment remain elusive. Our study shows that impairment of ACE2 pathway is a key factor linking virus infection to its secondary metabolic sequelae. By using structure-based high-throughput virtual screening and connectivity map database, followed with experimental validations, we identify imatinib, methazolamide, and harpagoside as direct enzymatic activators of ACE2. Imatinib and methazolamide remarkably improve metabolic perturbations in vivo in an ACE2-dependent manner under the insulin-resistant state and SARS-CoV-2-infected state. Moreover, viral entry is directly inhibited by these three compounds due to allosteric inhibition of ACE2 binding to spike protein on SARS-CoV-2. Taken together, our study shows that enzymatic activation of ACE2 via imatinib, methazolamide, or harpagoside may be a conceptually new strategy to treat metabolic sequelae of COVID-19.

Impact of non-pharmaceutical interventions on the incidences of vaccine-preventable diseases during the COVID-19 pandemic in the eastern of China.

BACKGROUND: In response to the coronavirus disease 2019 (COVID-19) pandemic, many countries have implemented mitigating non-pharmaceutical interventions. We investigated the impact of these interventions and changes in public behavior on the incidences of selected vaccine-preventable diseases (VPDs) during the COVID-19 pandemic in the eastern of China. METHODS: From routine monitoring data collected in the capital of eastern China's Jiangsu Province, we extracted and analyzed the incidences of influenza; hand, foot and mouth disease (HFMD); varicella; mumps; pertussis; and hepatitis B. We also investigated the changes in public behavior during the COVID-19 pandemic through telephone interviews and questionnaire surveys. RESULTS: Compared with the baseline (2017-2019), the incidences of all VPDs except influenza declined significantly in 2020 (HFMD decreased by 79.92%, varicella decreased by 7.71%, mumps decreased by 2.03%, pertussis decreased by 78.91%, and hepatitis B decreased by 0.31%). The reduction in reported cases in children (0-14 years) was greater than that in adults, and pertussis had the largest reduction (approximately 80%) in children. Influenza peaks in winter; in the three years before the COVID-19 pandemic, Influenza rates took an average of 10 weeks to recede to their lowest levels after the Spring Festival, while in 2020, this took only 1 week. A total of 366 outbreaks with 20,205 cases were reported during the COVID-19 pandemic. Among the participants in the study, 94.2% of the interviewees avoided going to high-risk areas, 82.4% avoided going to crowded places, 92.9% wore masks when going out,88.4% washed their hands frequently, and 67.9% maintained social distance. CONCLUSIONS: Our study showed significant reductions in the incidences of VPDs after the implementation of a series of non-pharmaceutical interventions during the COVID-19 pandemic.

Residual olfactory dysfunction in coronavirus disease 2019 patients after long term recovery.

INTRODUCTION: Hyposmia is among the most common symptoms of COVID-19 patients. Previous research has mainly described this issue at the disease's early stages. Because olfactory impairment can indicate neurological degeneration, we investigated the possibility of permanent olfactory damage by assessing hyposmia during the late recovery stage of COVID-19 patients. METHODS: Ninety-five patients were assessed with the Brief Smell Identification Test for Chinese (B-SITC) and Hyposmia Rating Scale (HRS) after 16 weeks from disease onset. Five weeks later, 41 patients were retested with B-SITC. RESULTS: At the first visit, hyposmia was identified in 26/82 (31.7%) and 22/95 (23.2%) of participants by HRS (HRS score ≤22) and B-SITC (B-SITC score <8), respectively. The rates of hyposmia in patients who performed B-SITC after 14-15 weeks, 16-17 weeks, and ≥18 weeks from disease onset were 7/25 (28%), 8/35 (23%) and 7/35 (20%), respectively, which demonstrated a trend of olfaction improvement as recovery time prolonging. Hyposmia percentages decreased from the first visit (34.1%) to the second visit (24.4%) for the 41 patients who completed 2 visits. B-SITC scores of the first-visit hyposmia participants increased significantly at the second visit (5.29 ± 2.02 to 8.29 ± 2.40; n = 14, P = 0.001). Severe cases tended to recover less than common cases. CONCLUSIONS: Hyposmia was present in up to one-third of COVID-19 patients after about 3 months from disease onset. Notable recovery of olfactory function was observed at a next 5-weeks follow-up. Clinical severity had little influence on olfactory impairment and recovery.

Assessment of emission reduction effect in Beijing, Tianjin and surrounding 26 cities from January to March in 2020 during the epidemic of COVID-19

In order to evaluate the effect of air pollutions emission reduction in Beijing, Tianjin, Hebei and its surrounding 26 cities（"2 + 26" cities） from January to March in 2020 during the epidemic of COVID-19, the air quality model of nested air quality prediction modeling system（NAQPMS） was applied to conduct a few scenarios. The characteristics of air quality from January to March 2020, and during the periods before and after the epidemic of COVID-19 were investigated. The influences of meteorology, emergency emission reduction measures and social economic activities on ambient air quality as well as the uncertainties were elucidated and discussed. The results showed that the number of days achieving good and moderate air quality standard in "2+26" cities accounted for 59.6%, on average of 10.9% increase relative to the same period last year. The mean concentration of PM10、PM2.5、SO2、NO2、O3-8 h-90 per and CO-95 per in "2 + 26" cities from January to March in 2020 were 108, 76, 14, 109, 36μg/m3, and 2.3 mg/m3, respectively. During the epidemic period from January 24 to March 31, the concentrations of PM10, NO2, PM2.5, and CO decreased significantly compared with the period prior to the epidemic from January 1 to 23. In contrast to January to March in 2019, the PM2.5 concentrations of the cities along the Yan mountain and Taihang mountain increased by 1%～8% in 2020. However, the model simulations revealed that the emergency emission reduction measures potentially avoided twice of the regional heavy air pollution events, resulting in the quarterly mean PM2.5 concentration in "2 + 26" cities reduced by 6 to 26μg/m3. Due to the influence of the Spring Festival holiday and epidemic, the traffic emissions were reduced substantially. In contrast, the emissions from the industry such as coking and thermal power did not show large variations, and the negative impact of loose coal combustion on ambient air quality may become even more severe.

An evaluation of mental health and emotion regulation experienced by undergraduate nursing students in China during the COVID-19 pandemic: A cross-sectional study.

The COVID-19 outbreak negatively impacted the mental health and emotions of many individuals. The study presented here explores the mental health and emotion regulation experienced by undergraduate nursing students in China during the pandemic. Potential risk factors related to negative mental health symptoms were identified in this study. An online cross-sectional study including 342 respondents was performed from March 6, 2020, to April 1, 2020, at a University in China. A Generalized Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-9 (PHQ-9), and Emotion Regulation Questionnaire (ERQ) were used to evaluate mental health and emotions. The statistical analysis was performed using the Statistical Package for Social Sciences (SPSS) version 22. The prevalence of anxiety, depression, or comorbid anxiety and depression were 55.0%, 56.4%, and 31.6%, respectively. The mean score of cognitive reappraisal and expressive suppression was 29.36 ± 8.00 and 15.55 ± 5.14. Lower scores for cognitive reappraisal and higher scores for expressive suppression were susceptible to symptoms of anxiety, depression, or comorbid anxiety and depression. Issues with mental health occurred in nursing students during the COVID-19 pandemic. Findings from this study provide a better understanding of the association between mental health and emotion regulation, which will help direct psychological intervention that relieves these issues during the pandemic.
