6551 | Side effects of BNT162b2 mRNA COVID-19 vaccine: A randomized, cross-sectional study with detailed self-reported symptoms from healthcare workers INTRODUCTION: Concerns are prevailing about the safety and side effects from BNT162b2 mRNA COVID-19 vaccine. METHODS: A randomized, cross-sectional study was performed to investigate the side effects of BNT162b2 vaccine using an independent online questionnaire gathering responses from healthcare workers (HCWs) with detailed review of organ systems. RESULTS: Of all HCWs, 87.98% (1245/1415) completed the survey. Of them, 64.5 % (803/1245) received BNT162b2 mRNA vaccine and reported at-least one or more symptoms (classified based on organ systems and occurrence rate) post-vaccination. Of these, 640/803 (79.7%) were able to continue activities of daily living (ADL), 103/803 (12.83%) were temporarily unable to perform ADL, 99/803 (12.33%) temporarily took off from work, only 20/803 (2.49%) required help from an outpatient provider, 5/803 (0.62%) required help from emergency department, and 2/803 (0.25%) required hospitalization. Despite, 97.61% had no intention to skip the second dose and 92.9% had already received it. CONCLUSIONS: The commonly reported symptoms (occurrence in the descending order) include soreness, fatigue, myalgia, headache, chills, fever, joint pain, nausea, muscle spasm, sweating, dizziness, flushing, feelings of relief, brain fogging, anorexia, localized swelling, decreased sleep quality, itching, tingling, diarrhea, nasal stuffiness, and palpitations. Despite, there is remarkable acceptance for the second dose among HCWs. | Int J Infect Dis | 2021 | | LitCov and CORD-19 |
6552 | Diabetes management and specific considerations for patients with diabetes during coronavirus diseases pandemic: A scoping review BACKGROUND AND AIMS: The global pandemic of coronavirus (COVID-19) affects almost all countries in the world, which potentially alter diabetes management. Many diabetes patients are experiencing barrier of care due to the policy related to COVID-19. This article aims to review the current evidence on diabetes management and specific consideration during the COVID-19 pandemic for people living with diabetes. METHODS: We conducted a scoping review in PubMed, Science Direct, DOAJ and Microsoft Academics databases from January 1 to April 17, 2020. Searching terms included “COVID-19, “severe acute respiratory syndrome coronavirus 2, and “Diabetes Mellitus” were used. Only scientific articles discussing diabetes management and specific considerations were selected and extracted. RESULTS: A total of 7 articles was selected in the analysis. Most were published in diabetes journals (85.71%). All articles (100%) discussed diabetes management and 71.43% of them provided diabetes care in specific considerations. We discussed issue of diabetes management in glycemic control and monitoring, dietary intake, physical activity, medication, education and prevention of COVID-19 infection that applicable for diabetes patients. In addition, specific considerations explored caring for diabetes in children and adolescents, pregnancy, elderly, emergency or critical care, to offer certain concern for raising the awareness. CONCLUSIONS: This review specifies a summary of diabetes management as well as the particular considerations to care people living with diabetes during COVID-19 pandemic. Patients, health care providers, and policy makers could take advantage of the review to assist diabetic people passing through COVID-19 pandemic session with optimum glycemic outcome. | Diabetes Metab Syndr | 2020 | | LitCov and CORD-19 |
6553 | Optimization of primer sets and detection protocols for SARS-CoV-2 of COVID-19 using PCR and real-time PCR SARS-CoV-2 is very contagious and has rapidly spread globally. Due to various symptomatic and asymptomatic cases and the possibility of asymptomatic transmission, there is a pressing need for a fast and sensitive detection protocol to diagnose asymptomatic people. Various SARS-CoV-2 diagnostic kits are already available from many companies and national health agencies. However, publicly available information on these diagnostic kits is lacking. In response to the growing need and the lack of information, we developed and made available a low-cost, easy-access, real-time PCR-based protocol for the early detection of the virus in a previous study. During the development of the detection protocol, we found that unoptimized primer sets could inadvertently show false-positive results, raising the possibility that commercially available diagnostic kits might also contain primer sets that produce false-positive results. Here, we provide three-step guidelines for the design and optimization of specific primer sets. The three steps include (1) the selection of primer sets for target genes (RdRP, N, E, and S) in the genome of interest (SARS-CoV-2), (2) the in silico validation of primer and amplicon sequences, and (3) the optimization of PCR conditions (i.e., primer concentrations and annealing temperatures) for specific hybridization between the primers and target genes, and the elimination of spurious primer dimers. Furthermore, we have expanded the previously developed real-time PCR-based protocol to more conventional PCR-based protocols and applied a multiplex PCR-based protocol that allows the simultaneous testing of primer sets for RdRP, N, E, and S all in one reaction. Our newly optimized protocol should be helpful for the large-scale, high-fidelity screening of asymptomatic people, even without any high-specification equipment, for the further prevention of transmission, and to achieve early intervention and treatment for the rapidly propagating virus. | Exp Mol Med | 2020 | | LitCov and CORD-19 |

6556 | Food Insecurity, the Home Food Environment and Parent Feeding Practices in the Era of COVID-19 OBJECTIVE: To describe changes in families’ home food environment and parent feeding practices, from before to during COVID‐19, and examine if changes differed by food security status. METHODS: Parents (N=584) in the US completed a single online survey, reporting on food security, home food availability, and feeding practices both retrospectively (considering before COVID‐19) and currently (during COVID‐19). Chi‐squares and univariate regressions examined associations by food security status. RESULTS: The percent of families reporting very low food security increased by 20% from before to during COVID‐19 (p<0.01). About one‐third of families increased the amount of high‐calorie snack foods, desserts/sweets, and fresh foods in their home; 47% increased non‐perishable processed foods. Concern about child overweight increased during COVID‐19, with a greater increase for food insecure vs. secure parents (p<0.01). Use of restriction, pressure to eat, and monitoring increased, with a greater increase in pressure to eat for parents with food insecurity compared to food secure parents (p<0.05). CONCLUSION: During COVID‐19, increases in very low food security and changes in the home food environment and parent feeding practices were observed. Results highlight the need to address negative impacts of COVID‐19 on children’s obesity risk, particularly among those facing health disparities. | Obesity (Silver Spring) | 2020 | | LitCov and CORD-19 |

6558 | Correlates of Protection Against SARS-CoV-2 in Rhesus Macaques Recent studies have reported protective efficacy of both natural immunity1 and vaccine-induced immunity(2–7) against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) challenge in rhesus macaques. However, the importance of humoral and cellular immunity for protection against SARS-CoV-2 infection remains to be determined. Here we show that adoptive transfer of purified IgG from convalescent macaques protects naïve recipient rhesus macaques against SARS-CoV-2 challenge in a dose dependent fashion. Depletion of CD8+ T cells in convalescent animals partially abrogated the protective efficacy of natural immunity against SARS-CoV-2 re-challenge, suggesting the importance of cellular immunity in the context of waning or subprotective antibody titers. These data demonstrate that relatively low antibody titers are sufficient for protection against SARS-CoV-2 in rhesus macaques, and that cellular immune responses may also contribute to protection if antibody responses are suboptimal. We also show that higher antibody titers are required for therapy of SARS-CoV-2 infection in macaques. These findings have important implications for the development of SARS-CoV-2 vaccines and immune-based therapeutics. | Nature | 2020 | | LitCov and CORD-19 |

6562 | Psychological resilience, depression, anxiety and somatization symptoms in response to COVID-19: A study of the general population in China at the peak of its epidemic RATIONALE: Psychological resilience is characterized as the ability to respond to extreme stress or trauma or adverse experience successfully. While the relation between public emergencies and psychological distress is well known, research on therelationship between psychological resilience and mental health is very limited during the outbreak of public health emergencies. OBJECTIVE: This research investigated the relationship between psychological resilience and mental health (depression, anxiety, somatization symptoms) among the general population in China. METHOD: Psychological resilience, depression, anxiety, and somatization symptoms of 1,770 Chinese citizens were investigated during the epidemic peak of coronavirus disease 2019 (COVID-19) (23rd February 2020 to 2nd March 2020). The analyses were done through the Connor-Davidson Resilience Scale (CD-RISC), the Patient Health Questionnaire-9 (PHQ-9), the Generalized Anxiety Disorder-7 (GAD-7) scale, and the Patient Health Questionnaire-15 (PHQ-15) scale. RESULTS: The prevalence of depression, anxiety, somatization symptoms was found to be 47.1%, 31.9%, 45.9%, respectively, among all participants. From them, 18.2% showed moderate to severe symptoms of depression, 8.8% showed moderate to severe symptoms of anxiety, and 16.6% showed moderate to severe symptoms of somatization. Psychological resilience was negatively correlated with depression (standardized B = -0.490, P<0.001), anxiety (standardized B = -0.443, P<0.001), and somatization symptom scores (standardized B = -0.358, P<0.001), while controlling for confounding factors. Analysis of the three-factor resilience structure showed that strength and tenacity were correlated with depression (standardized B = -0.256, P<0.001; standardized B = -0.217, P<0.001), anxiety (standardized B = -0.268, P<0.001; standardized B = -0.147, P<0.001), and somatization symptoms (standardized B = -0.236, P<0.001, standardized B = -0.126, P<0.01). CONCLUSIONS: Our results suggest that there is a high prevalence of psychological distresses among the general population at the peak of the COVID-19 epidemic in China, which is negatively correlated with resilience. Psychological resilience represents an essential target for psychological intervention in a public health emergency. | Soc Sci Med | 2020 | | LitCov and CORD-19 |
6563 | Challenges to the Poultry Industry: Current Perspectives and Strategic Future After the COVID-19 Outbreak Poultry immunity, health, and production are several factors that challenge the future growth of the poultry industry. Consumer confidence, product quality and safety, types of products, and the emergence and re-emergence of diseases will continue to be major challenges to the current situation and the strategic future of the industry. Foodborne and zoonotic diseases are strictly linked with poultry. Eradication, elimination, and/or control of foodborne and zoonotic pathogens present a major challenge to the poultry industry. In addition, the public health hazards from consuming foods with high antibiotic residues will remain a critical issue. The theory of poultry production described in this review will not be limited to considering disease control. Rather, it will also incorporate the interconnection of the animals' health, welfare, and immunity. It is essential to know that chickens are not susceptible to intranasal infection by the SARS-CoV-2 (COVID-19) virus. Nevertheless, the COVID-19 pandemic will affect poultry consumption, transport, and the economics of poultry farming. It will also take into consideration economic, ethical, social dimensions, and the sustenance of the accomplishment of high environmental security. Stockholders, veterinarians, farmers, and all the partners of the chain of poultry production need to be more involved in the current situation and the strategic future of the industry to fulfill human demands and ensure sustainable agriculture. Thus, the present review explores these important tasks. | Front Vet Sci | 2020 | | LitCov and CORD-19 |

6566 | Systematic Review of Changes and Recovery in Physical Function and Fitness After Severe Acute Respiratory Syndrome-Related Coronavirus Infection: Implications for COVID-19 Rehabilitation OBJECTIVES: 1) Compare physical function and fitness outcomes in people infected with SARS-CoV to healthy controls; 2) quantify the recovery of physical function and fitness following SARS-CoV infection; 3) determine the effects of exercise following SARS-CoV infection. METHODS: Four databases (CINAHL, MEDLINE, ProQuest, and Web of Science Core Collections) were searched in April 2020 using keywords relating to SARS-CoV, physical function, fitness, and exercise. Observational studies or randomised controlled trials were included if they involved people following SARS-CoV infection and either assessed the change or recovery in physical function/fitness or evaluated the effects exercise postinfection. RESULTS: 10 articles were included in this review. Evidence from nine articles demonstrated that SARS-CoV patients had reduced levels of physical function and fitness postinfection in comparison to healthy controls. Furthermore, patients demonstrated incomplete recovery of physical function, with some experiencing residual impairments 1 to 2 years postinfection. Evidence from one randomised controlled trial found that a combined aerobic and resistance training intervention significantly improved physical function and fitness postinfection in comparison to a control group. CONCLUSIONS: Physical function and fitness are impaired following SARS-CoV infection, and impairments may persist up to 1 to 2 years postinfection. Researchers and clinicians can use these findings to understand the potential impairments and rehabilitation needs of people recovering from the current COVID-19 outbreak. While one study demonstrated that exercise can improve physical function and fitness postinfection, further research is required to determine the effectiveness of exercise in people recovering from similar infections (eg, COVID-19). IMPACT STATEMENT: Considering the similarities in pathology and clinical presentation of SARS-CoV and COVID-19, it is likely that COVID-19 patients will present with similar impairments to physical function. Accordingly, research is required to measure the extent of functional impairments in COVID-19 cohorts. In addition, research should evaluate whether rehabilitation interventions such as exercise can promote postinfection recovery. | Phys Ther | 2020 | | LitCov and CORD-19 |
6567 | SARS-CoV-2 infection of the liver directly contributes to hepatic impairment in patients with COVID-19 BACKGROUND: Liver enzyme abnormality is common in patients with coronavirus disease 2019 (COVID-19). Whether or not SARS-CoV-2 infection can lead to liver damage per se remains unknown. Here we reported the clinical characteristics and liver pathological manifestations of COVID-19 patients with liver enzyme abnormality. METHODS: We received 156 patients diagnosed of COVID-19 from two designated centers in China, and compared clinical features between patients with elevated aminotransferase or not. Postmortem liver biopsies were obtained from two cases who had elevated aminotransferase. We investigated the patterns of liver impairment by electron microscopy, immunohistochemistry, TUNEL assay, and pathological studies. RESULTS: 64 of 156 (41.0%) COVID-19 patients had elevated aminotransferase. The median levels of ALT were 50 U/L vs. 19 U/L, respectively, AST were 45.5 U/L vs. 24 U/L, respectively in abnormal and normal aminotransferase groups. The liver enzyme abnormality was associated with disease severity, as well as a series of laboratory tests including higher A-aDO2, higher GGT, lower albumin, decreased CD4+ T cells and B lymphocytes. Ultrastructural examination identified typical coronavirus particles characterized by spike structure in cytoplasm of hepatocytes in two COVID-19 cases. SARS-CoV-2 infected hepatocytes displayed conspicuous mitochondrial swelling, endoplasmic reticulum dilatation, and glycogen granule decrease. Histologically, massive hepatic apoptosis and a certain binuclear hepatocytes were observed. Taken together, both ultrastructural and histological evidence indicated a typical lesion of viral infection. Immunohistochemical results showed scanty CD4+ and CD8+ lymphocytes. No obvious eosinophil infiltration, cholestasis, fibrin deposition, granuloma, massive central necrosis, or interface hepatitis were observed. CONCLUSIONS: SARS-CoV-2 infection in liver is a crucial cause of hepatic impairment in COVID-19 patients. Hence, a surveillance of viral clearance in liver and long outcome of COVID-19 is required. | J Hepatol | 2020 | | LitCov and CORD-19 |
6568 | SARS-CoV-2 binds platelet ACE2 to enhance thrombosis in COVID-19 BACKGROUND: Critically ill patients diagnosed with COVID-19 may develop a pro-thrombotic state that places them at a dramatically increased lethal risk. Although platelet activation is critical for thrombosis and is responsible for the thrombotic events and cardiovascular complications, the role of platelets in the pathogenesis of COVID-19 remains unclear. METHODS: Using platelets from healthy volunteers, non-COVID-19 and COVID-19 patients, as well as wild-type and hACE2 transgenic mice, we evaluated the changes in platelet and coagulation parameters in COVID-19 patients. We investigated ACE2 expression and direct effect of SARS-CoV-2 virus on platelets by RT-PCR, flow cytometry, Western blot, immunofluorescence, and platelet functional studies in vitro, FeCl(3)-induced thrombus formation in vivo, and thrombus formation under flow conditions ex vivo. RESULTS: We demonstrated that COVID-19 patients present with increased mean platelet volume (MPV) and platelet hyperactivity, which correlated with a decrease in overall platelet count. Detectable SARS-CoV-2 RNA in the blood stream was associated with platelet hyperactivity in critically ill patients. Platelets expressed ACE2, a host cell receptor for SARS-CoV-2, and TMPRSS2, a serine protease for Spike protein priming. SARS-CoV-2 and its Spike protein directly enhanced platelet activation such as platelet aggregation, PAC-1 binding, CD62P expression, α granule secretion, dense granule release, platelet spreading, and clot retraction in vitro, and thereby Spike protein enhanced thrombosis formation in wild-type mice transfused with hACE2 transgenic platelets, but this was not observed in animals transfused with wild-type platelets in vivo. Further, we provided evidence suggesting that the MAPK pathway, downstream of ACE2, mediates the potentiating role of SARS-CoV-2 on platelet activation, and that platelet ACE2 expression decreases following SARS-COV-2 stimulation. SARS-CoV-2 and its Spike protein directly stimulated platelets to facilitate the release of coagulation factors, the secretion of inflammatory factors, and the formation of leukocyte–platelet aggregates. Recombinant human ACE2 protein and anti-Spike monoclonal antibody could inhibit SARS-CoV-2 Spike protein-induced platelet activation. CONCLUSIONS: Our findings uncovered a novel function of SARS-CoV-2 on platelet activation via binding of Spike to ACE2. SARS-CoV-2-induced platelet activation may participate in thrombus formation and inflammatory responses in COVID-19 patients. | J Hematol Oncol | 2020 | | LitCov and CORD-19 |

6570 | Achievements and new knowledge unraveled by metagenomic approaches Metagenomics has paved the way for cultivation-independent assessment and exploitation of microbial communities present in complex ecosystems. In recent years, significant progress has been made in this research area. A major breakthrough was the improvement and development of high-throughput next-generation sequencing technologies. The application of these technologies resulted in the generation of large datasets derived from various environments such as soil and ocean water. The analyses of these datasets opened a window into the enormous phylogenetic and metabolic diversity of microbial communities living in a variety of ecosystems. In this way, structure, functions, and interactions of microbial communities were elucidated. Metagenomics has proven to be a powerful tool for the recovery of novel biomolecules. In most cases, functional metagenomics comprising construction and screening of complex metagenomic DNA libraries has been applied to isolate new enzymes and drugs of industrial importance. For this purpose, several novel and improved screening strategies that allow efficient screening of large collections of clones harboring metagenomes have been introduced. | Appl Microbiol Biotechnol | 2009 | | CORD-19 |

6574 | Metropolitan wastewater analysis for COVID-19 epidemiological surveillance The COVID-19 disease, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a rapidly emerging pandemic which has enforced extreme containment measures worldwide. In the absence of a vaccine or efficient treatment, cost-effective epidemiological surveillance strategies are urgently needed. Here, we have used RT-qPCR for SARS-CoV-2 detection in a series of longitudinal metropolitan wastewaters samples collected from February to April 2020, during the earliest stages of the epidemic in the Region of Valencia, Spain. We were able to consistently detect SARS-CoV-2 RNA in samples taken in late February, when communicated cases in that region were only incipient. We also find that the wastewater viral RNA context increased rapidly and anticipated the subsequent ascent in the number of declared cases. Our results strongly suggest that the virus was undergoing community transmission earlier than previously believed, and suggest that wastewater analysis could be sensitive and cost-effective strategy for COVID-19 epidemiological surveillance. Routine implementation of this surveillance tool would significantly improve our preparedness against new or re-occurring viral outbreaks. | Int J Hyg Environ Health | 2020 | | LitCov and CORD-19 |
6575 | Psychiatric face of COVID-19 The Coronavirus Disease 2019 (COVID-19) represents a severe multiorgan pathology which, besides cardio-respiratory manifestations, affects the function of the central nervous system (CNS). The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), similarly to other coronaviruses demonstrate neurotropism; the viral infection of the brain stem may complicate the course of the disease through damaging central cardio-respiratory control. The systemic inflammation as well as neuroinflammatory changes are associated with massive increase of the brain pro-inflammatory molecules, neuroglial reactivity, altered neurochemical landscape and pathological remodelling of neuronal networks. These organic changes, emerging in concert with environmental stress caused by experiences of intensive therapy wards, pandemic fears and social restrictions, promote neuropsychiatric pathologies including major depressive disorder, bipolar disorder (BD), various psychoses, obsessive-compulsive disorder and post-traumatic stress disorder. The neuropsychiatric sequelae of COVID-19 represent serious clinical challenge that has to be considered for future complex therapies. | Transl Psychiatry | 2020 | | LitCov and CORD-19 |

6577 | Stroke in COVID-19: A systematic review and meta-analysis BACKGROUND: Coronavirus disease 2019 (COVID-19) has become a global pandemic, affecting millions of people. However, the relationship between COVID-19 and acute cerebrovascular diseases is unclear. AIMS: We aimed to characterize the incidence, risk factors, clinical–radiological manifestations, and outcome of COVID-19-associated stroke. METHODS: Three medical databases were systematically reviewed for published articles on acute cerebrovascular diseases in COVID-19 (December 2019–September 2020). The review protocol was previously registered (PROSPERO ID = CRD42020185476). Data were extracted from articles reporting ≥5 stroke cases in COVID-19. We complied with the PRISMA guidelines and used the Newcastle–Ottawa Scale to assess data quality. Data were pooled using a random-effect model. SUMMARY OF REVIEW: Of 2277 initially identified articles, 61 (2.7%) were entered in the meta-analysis. Out of 108,571 patients with COVID-19, acute CVD occurred in 1.4% (95%CI: 1.0–1.9). The most common manifestation was acute ischemic stroke (87.4%); intracerebral hemorrhage was less common (11.6%). Patients with COVID-19 developing acute cerebrovascular diseases, compared to those who did not, were older (pooled median difference = 4.8 years; 95%CI: 1.7–22.4), more likely to have hypertension (OR = 7.35; 95%CI: 1.94–27.87), diabetes mellitus (OR = 5.56; 95%CI: 3.34–9.24), coronary artery disease (OR = 3.12; 95%CI: 1.61–6.02), and severe infection (OR = 5.10; 95%CI: 2.72–9.54). Compared to individuals who experienced a stroke without the infection, patients with COVID-19 and stroke were younger (pooled median difference = −6.0 years; 95%CI: −12.3 to −1.4), had higher NIHSS (pooled median difference = 5; 95%CI: 3–9), higher frequency of large vessel occlusion (OR = 2.73; 95%CI: 1.63–4.57), and higher in-hospital mortality rate (OR = 5.21; 95%CI: 3.43–7.90). CONCLUSIONS: Acute cerebrovascular diseases are not uncommon in patients with COVID-19, especially in those whom are severely infected and have pre-existing vascular risk factors. The pattern of large vessel occlusion and multi-territory infarcts suggests that cerebral thrombosis and/or thromboembolism could be possible causative pathways for the disease. | Int J Stroke | 2020 | | LitCov and CORD-19 |
6578 | COVID-19 and Liver Dysfunction: Current Insights and Emergent Therapeutic Strategies The outbreak of coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has attracted increasing worldwide attention. Cases of liver damage or dysfunction (mainly characterized by moderately elevated serum aspartate aminotransferase levels) have been reported among patients with COVID-19. However, it is currently uncertain whether the COVID-19-related liver damage/dysfunction is due mainly to the viral infection per se or other coexisting conditions, such as the use of potentially hepatotoxic drugs and the coexistence of systemic inflammatory response, respiratory distress syndrome-induced hypoxia, and multiple organ dysfunction. Based on the current evidence from case reports and case series, this review article focuses on the demographic and clinical characteristics, potential mechanisms, and treatment options for COVID-19-related liver dysfunction. This review also describes the geographical and demographic distribution of COVID-19-related liver dysfunction, as well as possible underlying mechanisms linking COVID-19 to liver dysfunction, in order to facilitate future drug development, prevention, and control measures for COVID-19. | J Clin Transl Hepatol | 2020 | | LitCov and CORD-19 |
6579 | Cluster of COVID-19 in the French Alps, 2020 BACKGROUND: On 07/02/2020, French Health authorities were informed of a confirmed case of SARS-CoV-2 coronavirus in an Englishman infected in Singapore who had recently stayed in a chalet in the French Alps. We conducted an investigation to identify secondary cases and interrupt transmission. METHODS: We defined as a confirmed case a person linked to the chalet with a positive RT-PCR sample for SARS-CoV-2. RESULTS: The index case stayed 4 days in the chalet with 10 English tourists and a family of 5 French residents; SARS-CoV-2 was detected in 5 individuals in France, 6 in England (including the index case), and 1 in Spain (overall attack rate in the chalet: 75%). One pediatric case, with picornavirus and influenza A coinfection, visited 3 different schools while symptomatic. One case was asymptomatic, with similar viral load as that of a symptomatic case. Seven days after the first cases were diagnosed, one tertiary case was detected in a symptomatic patient with a positive endotracheal aspirate; all previous and concurrent nasopharyngeal specimens were negative. Additionally, 172 contacts were monitored, including 73 tested negative for SARS-CoV-2. CONCLUSIONS: The occurrence in this cluster of one asymptomatic case with similar viral load as a symptomatic patient, suggests transmission potential of asymptomatic individuals. The fact that an infected child did not transmit the disease despite close interactions within schools suggests potential different transmission dynamics in children. Finally, the dissociation between upper and lower respiratory tract results underscores the need for close monitoring of the clinical evolution of suspect Covid-19 cases. | Clin Infect Dis | 2020 | | LitCov and CORD-19 |
6580 | COVID-19 in otolaryngologist practice: a review of current knowledge PURPOSE: Otorhinolaryngological manifestations are common symptoms of COVID-19. This study provides a brief and precise review of the current knowledge regarding COVID-19, including disease transmission, clinical characteristics, diagnosis, and potential treatment. The article focused on COVID-19-related information useful in otolaryngologist practice. METHODS: The Medline and Web of Science databases were searched without a time limit using terms “COVID-19”, “SARS-CoV-2” in conjunction with “otorhinolaryngological manifestation”, “ENT”, and “olfaction”. RESULTS: The most common otolaryngological dysfunctions of COVID-19 were cough, sore throat, and dyspnea. Rhinorrhea, nasal congestion and dizziness were also present. COVID-19 could manifest as an isolated sudden hyposmia/anosmia. Upper respiratory tract (URT) symptoms were commonly observed in younger patients and usually appeared initially. They could be present even before the molecular confirmation of SARS-CoV-2. Otolaryngologists are of great risk of becoming infected with SARS-CoV-2 as they cope with URT. ENT surgeons could be easily infected by SARS-CoV-2 during performing surgery in COVID-19 patients. CONCLUSION: Ear, nose and throat (ENT) symptoms may precede the development of severe COVID-19. During COVID-19 pandemic, patients with cough, sore throat, dyspnea, hyposmia/anosmia and a history of travel to the region with confirmed COVID-19 patients, should be considered as potential COVID-19 cases. An otolaryngologist should wear FFP3/N95 mask, glasses, disposable and fluid resistant gloves and gown while examining such individuals. Not urgent ENT surgeries should be postponed. Additional studies analyzing why some patients develop ENT symptoms during COVID-19 and others do not are needed. Further research is needed to determine the mechanism leading to anosmia. | Eur Arch Otorhinolaryngol | 2020 | | LitCov and CORD-19 |
6581 | Neuropathology of COVID-19: a spectrum of vascular and acute disseminated encephalomyelitis (ADEM)-like pathology We report the neuropathological findings of a patient who died from complications of COVID-19. The decedent was initially hospitalized for surgical management of underlying coronary artery disease. He developed post-operative complications and was evaluated with chest imaging studies. The chest computed tomography (CT) imaging results were indicative of COVID-19 and he was subsequently tested for SARS-CoV-2, which was positive. His condition worsened and he died after more than 2 weeks of hospitalization and aggressive treatment. The autopsy revealed a range of neuropathological lesions, with features resembling both vascular and demyelinating etiologies. Hemorrhagic white matter lesions were present throughout the cerebral hemispheres with surrounding axonal injury and macrophages. The subcortical white matter had scattered clusters of macrophages, a range of associated axonal injury, and a perivascular acute disseminated encephalomyelitis (ADEM)-like appearance. Additional white matter lesions included focal microscopic areas of necrosis with central loss of white matter and marked axonal injury. Rare neocortical organizing microscopic infarcts were also identified. Imaging and clinical reports have demonstrated central nervous system complications in patients’ with COVID-19, but there is a gap in our understanding of the neuropathology. The lesions described in this case provide insight into the potential parainfectious processes affecting COVID-19 patients, which may direct clinical management and ongoing research into the disease. The clinical course of the patient also illustrates that during prolonged hospitalizations neurological complications of COVID may develop, which are particularly difficult to evaluate and appreciate in the critically ill. | Acta Neuropathol | 2020 | | LitCov and CORD-19 |
6582 | AGA Institute Rapid Review of the Gastrointestinal and Liver Manifestations of COVID-19, Meta-Analysis of International Data and Recommendations for the Consultative Management of Patients with COVID-19 Abstract Background Multiple gastrointestinal (GI) symptoms including diarrhea, nausea/vomiting, and abdominal pain, as well liver enzyme abnormalities have been variably reported in patients with COVID-19. The AGA) Institute Clinical Guideline Committee and Clinical Practice Updates Committee performed a systematic review and meta-analysis of international data on GI and liver manifestations of COVID-19. Methods We performed a systematic literature search to identify published and unpublished studies using OVID Medline and pre-print servers (medRxiv, LitCovid, and SSRN) up until April 5 2020; major journal sites were monitored for US publications until April 19 2020. We analyzed the prevalence of diarrhea, nausea, vomiting, and abdominal pain as well as LFT abnormalities using a fixed effect model and assessed the certainty of evidence using GRADE. Results We identified 118 studies and used a hierarchal study selection process to identify unique cohorts. We performed a meta-analysis of 47 studies including 10,890 unique patients. Pooled prevalence estimates of GI symptoms was diarrhea 7.7% (95% CI 7.2-8.2), nausea/vomiting 7.8% (95% CI 7.1-8.5), abdominal pain 2.7% (95% CI 2.0-3.4). Most studies reported on hospitalized patients. The pooled prevalence of elevated liver abnormalities was: AST 15.0% (13.6 to 16.5) and ALT 15.0% (13.6 to 16.4). When analyzed comparing data from China to studies from countries other than China, diarrhea, nausea/vomiting, liver abnormalities were more prevalent outside of China with diarrhea reported in 18.3% (16.6 to 20.1). Isolated GI symptoms were rarely reported. We also summarized of the Gl and liver adverse effects of the most commonly utilized medications for COVID19 Conclusions GI symptoms are associated with COVID-19 in less than 10% of patients. In studies outside of China, estimates are higher. Further studies are needed with standardized GI symptoms questionnaires and LFT checks on admission to better quantify and qualify the association of these symptoms with COVID-19. Based on findings from our meta-anlaysis, we make several Best Practice Statements for the consultative management of COVID-19. | Gastroenterology | 2020 | | LitCov and CORD-19 |

6584 | Recommendations for Keeping Parks and Green Space Accessible for Mental and Physical Health During COVID-19 and Other Pandemics The importance of engaging in any type of physical activity regularly, for both physical and mental health, is well established, and may be particularly beneficial in protecting the body and limiting the damage caused by the coronavirus disease 2019 (COVID-19). Exposure to nature or green space also has positive physical and mental health benefits. Closures of parks and green spaces during the COVID-19 pandemic has limited the options for physical activity and may affect vulnerable populations more than others. We provide both short-term and long-term recommendations to encourage access to green space for people while allowing for physical distancing. | Prev Chronic Dis | 2020 | | LitCov and CORD-19 |
6585 | Characteristics and outcomes of patients hospitalized for COVID-19 and cardiac disease in Northern Italy AIMS: To compare demographic characteristics, clinical presentation, and outcomes of patients with and without concomitant cardiac disease, hospitalized for COVID-19 in Brescia, Lombardy, Italy. METHODS AND RESULTS: The study population includes 99 consecutive patients with COVID-19 pneumonia admitted to our hospital between 4 March and 25 March 2020. Fifty-three patients with a history of cardiac disease were compared with 46 without cardiac disease. Among cardiac patients, 40% had a history of heart failure, 36% had atrial fibrillation, and 30% had coronary artery disease. Mean age was 67 ± 12 years, and 80 (81%) patients were males. No differences were found between cardiac and non-cardiac patients except for higher values of serum creatinine, N-terminal probrain natriuretic peptide, and high sensitivity troponin T in cardiac patients. During hospitalization, 26% patients died, 15% developed thrombo-embolic events, 19% had acute respiratory distress syndrome, and 6% had septic shock. Mortality was higher in patients with cardiac disease compared with the others (36% vs. 15%, log-rank P = 0.019; relative risk 2.35; 95% confidence interval 1.08–5.09). The rate of thrombo-embolic events and septic shock during the hospitalization was also higher in cardiac patients (23% vs. 6% and 11% vs. 0%, respectively). CONCLUSIONS: Hospitalized patients with concomitant cardiac disease and COVID-19 have an extremely poor prognosis compared with subjects without a history of cardiac disease, with higher mortality, thrombo-embolic events, and septic shock rates. | Eur Heart J | 2020 | | LitCov and CORD-19 |
6586 | Treatment With Lopinavir/Ritonavir or Interferon beta1b Improves Outcome of MERS-CoV Infection in a Nonhuman Primate Model of Common Marmoset Middle East respiratory syndrome coronavirus (MERS-CoV) causes severe disease in human with an overall case-fatality rate of >35%. Effective antivirals are crucial for improving the clinical outcome of MERS. Although a number of repurposed drugs, convalescent-phase plasma, antiviral peptides, and neutralizing antibodies exhibit anti-MERS-CoV activity in vitro, most are not readily available or have not been evaluated in nonhuman primates. We assessed 3 repurposed drugs with potent in vitro anti-MERS-CoV activity (mycophenolate mofetil [MMF], lopinavir/ritonavir, and interferon-β1b) in common marmosets with severe disease resembling MERS in humans. The lopinavir/ritonavir-treated and interferon-β1b-treated animals had better outcome than the untreated animals, with improved clinical (mean clinical scores ↓50.9%–95.0% and ↓weight loss than the untreated animals), radiological (minimal pulmonary infiltrates), and pathological (mild bronchointerstitial pneumonia) findings, and lower mean viral loads in necropsied lung (↓0.59–1.06 log(10) copies/glyceraldehyde 3-phosphate dehydrogenase [GAPDH]; P < .050) and extrapulmonary (↓0.11–1.29 log(10) copies/GAPDH; P < .050 in kidney) tissues. In contrast, all MMF-treated animals developed severe and/or fatal disease with higher mean viral loads (↑0.15–0.54 log(10) copies/GAPDH) than the untreated animals. The mortality rate at 36 hours postinoculation was 67% (untreated and MMF-treated) versus 0–33% (lopinavir/ritonavir-treated and interferon-β1b-treated). Lopinavir/ritonavir and interferon-β1b alone or in combination should be evaluated in clinical trials. MMF alone may worsen MERS and should not be used. | J Infect Dis | 2015 | | CORD-19 |
6587 | Impact of the COVID-19 Pandemic on Partner Relationships and Sexual and Reproductive Health: Cross-Sectional, Online Survey Study BACKGROUND: In the past few months, the coronavirus disease (COVID-19) pandemic has caused extensive economic and social damage. OBJECTIVE: The purpose of this study was to assess the impact of COVID-19–related measures on partner relationships and sexual and reproductive health in China. METHODS: From May 1 to 5, 2020, 3500 young Chinese individuals were recruited through WeChat or Weibo to participate in a survey to obtain information on sexual and reproductive health (eg, sexual desire, frequency of sexual intercourse, sexual satisfaction, etc). The questionnaire also collected demographic data (eg, age, race, education, current financial status, sexual orientation, relationship status, etc). RESULTS: In total, 967 participants were included in the sexual health analysis. Due to the COVID-19 pandemic and related containment measures, 22% of participants (n=212) reported a decrease in sexual desire; 41% (n=396) experienced a decrease in the sexual intercourse frequency; 30% (n=291) reported an increase in the frequency of masturbation; 20% (n=192) reported a decrease in alcohol consumption before or during sexual activities, and 31% (n=298) reported a deterioration in partner relationships during the pandemic. The logistic regression analysis indicated that the following influenced partner relationships: accommodations during the pandemic (P=.046; odds ratio [OR] 0.59; 95% CI 0.30-0.86); exclusive relationship status (yes or no) (P<.001; OR 0.44; 95 % CI 0.27-0.73); sexual desire (P=.02; OR 2.01; 95% CI 1.38-2.97); and sexual satisfaction (P<.001; OR 1.92; 95% CI 1.54-2.50). COVID-19 also caused disruptions in reproductive health services such as prenatal and postnatal care, childbirth and abortion services, contraception availability, and the management of sexually transmitted infections. CONCLUSIONS: Our results show that many young people have wide-ranging issues affecting their sexual and reproductive health due to the COVID-19 pandemic and related containment measures. Strategies and guidelines are needed to safeguard the sexual and reproductive health of young people during this pandemic. | J Med Internet Res | 2020 | | LitCov and CORD-19 |

6591 | A Review of Vat Photopolymerization Technology: Materials, Applications, Challenges and Future Trends of 3D Printing Additive manufacturing (3D printing) has significantly changed the prototyping process in terms of technology, construction, materials, and their multiphysical properties. Among the most popular 3D printing techniques is vat photopolymerization, in which ultraviolet (UV) light is deployed to form chains between molecules of liquid light-curable resin, crosslink them, and as a result, solidify the resin. In this manuscript, three photopolymerization technologies, namely, stereolithography (SLA), digital light processing (DLP), and continuous digital light processing (CDLP), are reviewed. Additionally, the after-cured mechanical properties of light-curable resin materials are listed, along with a number of case studies showing their applications in practice. The manuscript aims at providing an overview and future trend of the photopolymerization technology to inspire the readers to engage in further research in this field, especially regarding developing new materials and mathematical models for microrods and bionic structures. | Polymers (Basel) | 2021 | | CORD-19 |

6593 | Airborne bioaerosols and their impact on human health Bioaerosols consist of aerosols originated biologically such as metabolites, toxins, or fragments of microorganisms that are present ubiquitously in the environment. International interests in bioaerosols have increased rapidly to broaden the pool of knowledge on their identification, quantification, distribution, and health impacts (e.g., infectious and respiratory diseases, allergies, and cancer). However, risk assessment of bioaerosols based on conventional culture methods has been hampered further by several factors such as: (1) the complexity of microorganisms or derivatives to be investigated; (2) the purpose, techniques, and locations of sampling; and (3) the lack of valid quantitative criteria (e.g., exposure standards and dose/effect relationships). Although exposure to some microbes is considered to be beneficial for health, more research is needed to properly assess their potential health hazards including inter-individual susceptibility, interactions with non-biological agents, and many proven/unproven health effects (e.g., atopy and atopic diseases). | J Environ Sci (China) | 2017 | | CORD-19 |

6596 | Applications of gold nanoparticles in virus detection Viruses are the smallest known microbes, yet they cause the most significant losses in human health. Most of the time, the best-known cure for viruses is the innate immunological defense system of the host; otherwise, the initial prevention of viral infection is the only alternative. Therefore, diagnosis is the primary strategy toward the overarching goal of virus control and elimination. The introduction of a new class of nanoscale materials with multiple unique properties and functions has sparked a series of breakthrough applications. Gold nanoparticles (AuNPs) are widely reported to guide an impressive resurgence in biomedical and diagnostic applications. Here, we review the applications of AuNPs in virus testing and detection. The developed AuNP-based detection techniques are reported for various groups of clinically relevant viruses with a special focus on the applied types of bio-AuNP hybrid structures, virus detection targets, and assay modalities and formats. We pay particular attention to highlighting the functional role and activity of each core Au nanostructure and the resultant detection improvements in terms of sensitivity, detection range, and time. In addition, we provide a general summary of the contributions of AuNPs to the mainstream methods of virus detection, technical measures, and recommendations required in guidance toward commercial in-field applications. | Theranostics | 2018 | | CORD-19 |
6597 | Epidemiologic surveillance for controlling Covid-19 pandemic: types, challenges and implications The objectives of the study was to determine the types, challenges and implications of surveillance methods for controlling Covid-19 pandemic. An integrative article review was done. The source of data were documents from WHO, Euro-surveillance, CDC, Saudi CDC, MOH, and journals from PubMed, Medline, etc. The inclusion searching criteria were surveillance, Covid-19, types, benefits and challenges, during the period 2005−2020. Published studies, reviews and guidelines that determined these criteria were collected. Data extraction and analysis were completed for all included articles. A critical appraisal was done based on the University of Michigan Practice Guideline’s levels of evidence. The final sample for the integrative review comprised 30 studies. Results revealed that types of Covid-9 surveillance includes routine surveillance (comprehensive, case-based, and aggregated weakly methods), active, wildlife, syndromic, sentinel and sentinel-syndromic methods. Laboratory and hospital-based surveillance are another important types. Help-lines, surveys, participatory electronic, digital and event-based surveillance are relatively new cost-effective methods. Many surveillance indicators can be calculated. Timely and accurate of surveillance data is an essential element for effective Covid-19 interventions. Regarding challenges, the quality of surveillance in developing countries is constrained by resources and training. The main limitations of surveillance are under-ascertainment/under-reporting, lack of timeliness and completeness of surveillance data. In conclusion, surveillance is a cornerstones for controlling Covid-19 pandemic. Enhancing Covid-19 surveillance is vital for rapid cases detection, containing spread & ending pandemic. | J Infect Public Health | 2020 | | LitCov and CORD-19 |
6598 | Effects of Covid-19 outbreak on environment and renewable energy sector Many articles have been written in the medical field related to the Covid-19 outbreak that has surrounded the World and killed many people. However, its environmental and energy impacts have not been sufficiently studied. Some sources argue that Covid-19 outbreak reduces pollution environmentally, while others say that environmentally significant damages await us. On the other hand, it is wondered how the global flexible renewable energy sector will react to Covid-19 outbreak. In this study, the effects of Covid-19 outbreak in terms of the environment and renewable energy sector in the literature were examined in detail and the findings obtained were discussed. The main aim of this study is to shed light on the future studies of environmental and renewable energy researchers. | Environ Dev Sustain | 2020 | | LitCov and CORD-19 |
6599 | SARS-CoV-2 and the COVID-19 disease: a mini review on diagnostic methods Coronavirus disease 2019 (COVID-19) is an infectious disease initially reported in China and currently worldwide dispersed caused by a new coronavirus (SARS-CoV-2 or 2019-nCoV) affecting more than seven million people around the world causing more than 400 thousand deaths (on June 8(th), 2020). The diagnosis of COVID-19 is based on the clinical and epidemiological history of the patient. However, the gold standard for COVID-19 diagnosis is the viral detection through the amplification of nucleic acids. Although the quantitative Reverse-Transcription Polymerase Chain Reaction (RT-PCR) has been described as the gold standard for diagnosing COVID-19, there are several difficulties involving its use. Here we comment on RT-PCR and describe alternative tests developed for the diagnosis of COVID-19. | Rev Inst Med Trop Sao Paulo | 2020 | | LitCov and CORD-19 |
6600 | COVID-19: a meta-analysis of diagnostic test accuracy of commercial assays registered in Brazil Abstract The accuracy of commercially available tests for COVID-19 in Brazil remains unclear. We aimed to perform a meta-analysis to describe the accuracy of available tests to detect COVID-19 in Brazil. We searched at the Brazilian Health Regulatory Agency (ANVISA) online platform to describe the pooled sensitivity (Se), specificity (Sp), diagnostic odds ratio (DOR) and summary receiver operating characteristic curves (SROC) for detection of IgM/IgG antibodies and for tests using naso/oropharyngeal swabs in the random-effects models. We identified 16 tests registered, mostly rapid-tests. Pooled diagnostic accuracy measures [95%CI] were: (i) for IgM antibodies Se=82% [76-87]; Sp=97% [96-98]; DOR=168 [92-305] and SROC=0.98 [0.96-0.99]; (ii) for IgG antibodies Se=97% [90-99]; Sp=98% [97-99]; DOR=1994 [385-10334] and SROC=0.99 [0.98-1.00]; and (iii) for detection of SARS-CoV-2 by antigen or molecular assays in naso/oropharyngeal swabs Se=97% [85-99]; Sp=99% [77-100]; DOR=2649 [30-233056] and SROC=0.99 [0.98-1.00]. These tests can be helpful for emergency testing during the COVID-19 pandemic in Brazil. However, it is important to highlight the high rate of false negative results from tests which detect SARS-CoV-2 IgM antibodies in the initial course of the disease and the scarce evidence-based validation results published in Brazil. Future studies addressing the diagnostic performance of tests for COVID-19 in the Brazilian population are urgently needed. | Braz J Infect Dis | 2020 | | LitCov and CORD-19 |
