ABSTRACT

Due to their geographical isolation and small populations, insular bats may not be able to maintain acute immunising viruses that rely on a large population for viral maintenance. Instead, endemic transmission may rely on viruses establishing persistent infections within hosts or inducing only short-lived neutralizing immunity. Therefore, studies on insular populations are valuable for developing broader understanding of viral maintenance in bats. The Christmas Island flying-fox (CIFF;Pteropus natalis) is endemic on Christmas Island, a remote Australian territory, and is an ideal model species to understand viral maintenance in small, geographically isolated bat populations. Serum or plasma (n = 190), oral swabs (n = 199), faeces (n = 31), urine (n = 32) and urine swabs (n = 25) were collected from 228 CIFFs. Samples were tested using multiplex serological and molecular assays, and attempts at virus isolation to determine the presence of paramyxoviruses, betacoronaviruses, and Australian bat lyssavirus. Analysis of serological data provide evidence that the species is maintaining a pararubulavirus and a betacoronavirus. There was little serological evidence supporting the presence of active circulation of the other viruses assessed in the present study. No viral nucleic acid was detected and no viruses were isolated. Age-seropositivity results support the hypothesis that geographically isolated bat populations can maintain some paramyxoviruses and coronaviruses. Further studies are required to elucidate infection dynamics and characterise viruses in the CIFF. Lastly, apparent absence of some pathogens could have implications for the conservation of the CIFF if a novel disease were introduced into the population through human carriage or an invasive species. Adopting increased biosecurity protocols for ships porting on Christmas Island and for researchers and bat carers working with flying-foxes are recommended to decrease the risk of pathogen introduction and contribute to the health and conservation of the species.

ABSTRACT

Objective: Healthcare professionals taking care of COVID-19 patients are considered to be at high risk for acquiring infection, and the protection of healthcare professionals is one of the top priorities. Inadequate knowledge of the disease by healthcare professionals and their inability to access or use personal protective equipment (PPE) required for protection may cause rapidly spreading of infection. In this study, we aimed to evaluate the knowledge levels of healthcare professionals regarding COVID-19 and PPE use.

ABSTRACT

Bilateral multilobar ground-glass opacities are characteristic features of COVID-19 pneumonia. However, the differential diagnosis of ground-glass opacities is challenging. The aim of this paper was to share our experiences with other colleagues. The first patient presented with anosmia and loss of taste. Legionella antigen in urine was positive. The second patient had bilateral ground-glass opacities, which predominantly involved the upper lung zones and lymphopenia. Radiological findings were the same with the radiological control of 8 months ago, and she had a diagnosis of sarcoidosis. The third patient complained of dyspnoea. The inspection of national health system records showed a histological diagnosis of nonspecific interstitial/organizing pneumonia. The fourth patient had findings suggestive of congestive heart failure such as bilateral pleural effusion, peribronchial cuffing, and interlobular septa thickening. The co-existence of multiple ill-defined centrilobular ground-glass opacities suggested a concomitant disease but lesions disappeared with furosemid infusion within 5 days. The fifth patient presented with only right upper lobe consolidation. The opacities did not exceed the horizontal fissure. The intact fissure suggested a bacterial aetiology, but PCR tests of the nasopharyngeal samples were positive for COVID-19. This finding suggested that pulmonary infiltrate of COVID-19 was inflammatory rather than infective in nature. In conclusion, old imaging studies were more useful in the differential diagnosis.

ABSTRACT

This note examines the impact of the Covid-19 pandemic on food security and indebtedness among rural households in India. Specifically, discusses the impact of the Covid-19 pandemic on food consumption and the public distribution system (PDS), indebtedness and sale of assets, and income support in October 2020. Results show that six months into the pandemic, around 45 per cent of the sample households reported a reduction in their usual food consumption. The impact was different for different socio-economic classes across the villages. The more vulnerable groups, for example, Scheduled Caste households and manual worker households, were worse affected. Around 68 per cent of manual wage workers and 38 per cent of poor peasants reported less food intake in September 2020 than in the pre-Covid period because of reduced employment and earnings and the soaring prices of food commodities. Fifty-six per cent of Scheduled Caste households reported lower food consumption that month than in the pre-pandemic period. The public distribution system (PDS) played a pivotal role in providing food to households. DS functioning was more efficient in Andhra Pradesh, Punjab, and Tamil Nadu than in Bihar and Tripura. Several respondents in West Bengal and Tripura reported that they were unable to get food from the PDS. The reasons cited were bureaucratic delays and shortages of foodgrain stocks. A little over a third (58 out of 164) of study households took loans to manage the livelihood crisis imposed by the pandemic. More than 80 per cent of these households took loans from informal lenders.

ABSTRACT

Covid-19, which affects the whole world and is accepted as a pandemic by the world health organization, caused millions of people to die. The elderly are in the group with the highest risk of losing their lives due to the Covid-19 virus. Stricter restrictive / protective measures have been taken for the elderly in Turkey, as in the whole world. With this research, it is aimed to evaluate the sociological and psychological effects of the "elderly", who are one of the health risk groups of the society, in terms of landscape architecture, during the pandemic days when they had to experience various problems after the outbreak. In the study, face-to-face and online questionnaires were applied to individuals aged 50 and over on a voluntary basis. As a result of the study, it was determined that the implementation of curfews and restrictions for the elderly and the formation of an isolated lifestyle from other age groups caused an increase in loneliness and anxiety levels and negative psychological effects. It has been revealed that the activities that individuals will carry out in the green area, their conversations and socializing with their peers, and walks in the open area have a positive psychological and sociological effect for the elderly. It has been determined that the elderly who become lonely and depressed at home with the restrictions imposed under pandemic conditions want to be in green areas. The sociological and psychological positive effects of being in green areas and spending time, and the changes in the behaviour and emotions of the elderly who have pandemic restrictions paralleled the response of the participants to the questionnaire.

ABSTRACT

In December 2019, the coronavirus disease COVID-19 began in China. Since then, millions of infections and deaths from this cause have been reported worldwide, particularly among health workers who have suffered the harsh onslaught of the pandemic in the context of healthcare systems collapsed by demand. In this sense, the objective of this work was to determine the prevalence, sociodemographic, epidemiological, and clinical characteristics of COVID-19 present in health workers of the "Instituto Aut..nomo Hospital Universitario de Los Andes" in M..rida-Venezuela. An observational, retrospective, single-center, documentary study was carried out, where 297 clinical-epidemiological records corresponding to 285 health workers were analyzed, in a period between March 16 and November 30, 2020. The records were separated into two groups, front-line workers and support workers. The overall positivity of the RT-PCRs performed was 31.6%. The frequency of positive confirmatory results was highest among support workers at 33.9%. Nursing staff had the highest positivity (39.5%). A seroprevalence of 34.3% was found in immunological tests. The prevalence of SARS-CoV-2 infection among health care workers was higher among support workers compared to front-line workers. Therefore, general and work-specific prevention strategies should be strengthened to limit the spread of SARS-CoV-2 among staff to ensure that they perform safely and effectively.

ABSTRACT

Hyperglycemia, with or without diabetes, is associated with complications in hospitalized patients with COVID-19. There is no informa- tion regarding this problem in our region. This study was aimed to compare the characteristics and in-hospital clinical course of patients with a probable diagnosis of COVID-19, with and without hyperglycemia during the hospital- ization. This is a retrospective, observational study of clinical records review of hospitalized patients with COVID-19. The ISARIC-WHO form was used for data collection. Hyperglycemia was defined as a fasting value 140 mg/dL ac- cording to standard glycaemia targets in hospitalized patients. A total of 148 patients were included, 97 (65.5%) men and 51 (34.5%) women, with a mean age of 64.1..16.1 years;of which 42/148 (28.4%) patients reported previous diabetes, 60/148 (40.5%) patients had hyperglycemia during the hospitaliza- tion and 32/60 (53.3%) of these cases did not report previous diabetes. The patients with hyperglycemia were older, received more frequently systemic cor- ticosteroids (96.6 vs 82.6%;p=0.01), and antibiotics (68.3 vs 44.3%;p=0.01), had worse baseline oxygenation parameters (SpO 2 88.1..11.7%;vs 92.8..5.5%;p=0.02, PaO 2 /FiO 2, 194.4..119.7 vs 270.9..118.3;p<0.001), higher total lung severity score in the chest CT (14.9..5.7 vs 11.1..6.3;p<0.001) and higher lev- els of baseline inflammatory markers (CRP 6.73..3.61 vs 5.08..4.21;p<0.01, LDH 342.9..118.4 vs 296.5..161.4;p=0.01 and Ferritin 687.7..373.2 vs 542.6..395.3;p=0.01). Mortality (34.5 vs 10.7%;p<0.001) and admission to ICU (43.3 vs 7.9%;p<0.001) were higher in patients with hyperglycemia. Hyperglycemia in hospitalized patients with COVID-19 is a marker of seve- re disease and poor prognosis.

ABSTRACT

Diseases caused by the coronavirus have become an important concern in early 2020. The coronavirus is a new type of virus that is included in the SARS-CoV-2 group. One of the possible mechanisms of SARS-CoV-2 inhibition involves protease receptors inhibition. This research was aimed to in silico screening of Ziziphus spina-christi (L.) Desf., and Strychnos ligustrine active ingredients as the main protease inhibitors of SARS-CoV-2 by assessing the ligand-binding affinity in the binding pocket of SARS-CoV-2 main protease protein. The molecular docking method is generally used to predict the inhibitory site and bonds formation. In the current study, some generally used antiviral compounds from the PDB (Protein Data Bank) were also used to compare the affinity strength of the test compound against the protease receptor (code of 5R7Y). The inhibitory activity against the main protease receptor proven by the ChemPLP score is more negative than the receptor's native ligand and the comparison compounds. Jubanine B, a compound of Z. spina-christi has the most robust inhibition activity on the SARS-CoV-2 protease receptor. Results of this study can be concluded that this can be used to develop as a candidate for traditional medicine against SARS-CoV-2 but still it required some more in vitro and in vivo studies.

ABSTRACT

What is already known about this topic? Lesbian, gay, bisexual, and transgender (LGBT) persons are at increased risk for severe COVID-19 illness because of a higher prevalence of comorbidities. What is added by this report? COVID-19 vaccination coverage and vaccine confidence were higher among gay or lesbian adults than among heterosexual adults and higher among gay men than gay or lesbian women. There were no significant differences in vaccination coverage among persons based on gender identity. Vaccination coverage was lowest among non-Hispanic Black LGBT persons across all categories of sexual orientation and gender identity. What are the implications for public health practice? To prevent serious illness and death, all persons in the United States, including those in the LGBT community, should stay up to date with recommended COVID-19 vaccinations.

ABSTRACT

Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been a global pandemic. Safe and effective vaccination is critical to ending the epidemic of COVID-19. Although randomized clinical trials are considered the "gold standard" for evaluating intervention effects of vaccines, they have notable limitations. As mass vaccination campaigns against COVID-19 commence worldwide, vaccine effectiveness needs to be assessed for a range of outcomes across diverse populations in a noncontrolled setting. Meanwhile, SARS-CoV-2 variants continue to emerge during the global pandemic and may facilitate escape from current vaccine immune protection. Hence, COVID19 vaccines faced many challenges, such as safety, immunogenicity, and efficacy of the COVID-19 Vaccine in special populations, the duration of protective effectiveness, viral mutations and breakthrough infection, antibody-dependent enhancement effect, and pathogenic autoimmune and so on. This article summarizes th.

ABSTRACT

Comparing the accuracy of antibody detection reagents which based on different principles by the diagnosis of suspected cases of new crown, propose an efficient screening plan for suspected cases, and further provide a scientific basis for establishing a clinical screening path for high-risk populations. For 76 suspected cases of COVID-19 that were transferred to designated hospitals for isolation and observation due to the initial IgM antibody test, nasopharyngeal swab nucleic acid tests, serum trace virus neutralizing antibodies and three commercially available antibody test reagents with different principles were tested, combined with lung CT and the examination and clinical symptoms or other information, comprehensively judge the diagnosis or exclusion of the new crown, and compare the three kinds of serological antibody detection reagents with the clinical judgment results to compare the detection rates of the three detection methods. Through comprehensive judgment, 3 suspected cases are confirmed cases, and 73 suspected cases are excluded cases. Compared with the clinical diagnosis/exclusion results, among the three serological antibody detection methods, the chemiluminescence total antibody kit detect positive for all the 9 serums collected from the 3 confirmed cases in different time points, the detection specificity is 97.26% for 73 excluded cases, it's significantly higher than that of the chemiluminescence method IgM/IgG and the colloidal gold method IgM/IgG Separate testing (the specificity is 73.97% on the first day of admission). The chemiluminescence method for the detection of total antibodies to the 2019-nCoV has high sensitivity and high specificity, and can be used for preliminary screening of antibody detection in suspected cases. For the screening of target populations, the 2019-nCoV nucleic acid test should be performed first. If the nucleic acid test is negative, the screening path with the detection of serum total antibodies as the main indicator should be adopted.
